III.     Pioneer Portfolio:

As of the date of this filing, the Company has determined that it is probable 
that the Operating Partnership will acquire a portfolio of 11 office 
properties and one industrial property (the "Pioneer Portfolio") located in 
Northern New York state containing 804,344 leasable square feet. The Company 
anticipates closing on the Pioneer Portfolio in August 1998. As part of this 
transaction, the Company and the Operating Partnership have also agreed to 
acquire three additional office properties (One Park Place, Waterfront I and 
Waterfront II) which aggregate an additional 530,636 square feet. The closing 
of the acquisitions of One Park Place and Waterfront I are expected to occur 
in September 1998. Waterfront II is to be acquired upon the completion of its 
construction, which is expected in December 1998. The Company and its 
Operating Partnership also have the option to acquire two additional 
properties located in Rochester, New York. As of June 30, 1998, the Pioneer 
Portfolio was leased to 67 tenants. Niagara Mohawk, Inc. occupies more than 
10% of the total leasable area of the Pioneer Portfolio. No assurance can be 
given that this transaction will be consummated as it is subject to various 
closing conditions. This transaction is subject to customary closing 
conditions and therefore can be no assurances the transaction will close or 
that if the transaction closes the Pioneer Portfolio will perform as expected.

The purchase price of the Pioneer Portfolio, including closing costs and the
purchase price of One Park Place, and Waterfront I and II totals approximately
$131,401,000, including closing costs, and will be funded through from 
the Company's Credit Facility, $16,325,000 of assumed indebtedness and the 
issuance of 1,626,794 units of limited partnership interest in the Operating 
Partnership. In addition, the Company may issue up to approximately 720,000 
shares of its Common Stock to a lender as partial repayment of certain of the 
indebtedness encumbering certain of the properties. The price at which the 
shares will be issued has not yet been determined.

The sellers of the Pioneer Portfolio consist of various entities affiliated 
with Pioneer Development Company, LLC, and Michael J. Falcone, both parties 
unaffiliated with the Company and the Operating Partnership. The Company 
based its determination of the purchase price of the Pioneer Portfolio on the 
expected cash flow, physical condition, location, competitive advantage, 
existing tenancies and opportunities to retain and attract additional 
tenants. The purchase price was determined by arm's length negotiation 
between the Company and the sellers. After the consummation of this 
transaction, Michael J. Falcone will become a director of the Company.

The following sets forth the unaudited pro forma condensed consolidating balance

statements of operations for American Real Estate Investment Corporation (the
"Company") for the three months ended March 31, 1998 and the year ended December
31, 1997.

The pro forma condensed consolidating financial information should be read in
conjunction with the historical financial statements of the Company and those
acquisitions deemed significant pursuant to the rules and regulations of the
Securities and Exchange Commission.

The unaudited pro forma consolidating financial information is presented as if
the following events occurred on March 31, 1998 for balance sheet purposes, on
January 1, 1997 for purposes of the statement of operations:

- -    The Company acquired the properties described in Note 1 to these pro forma
     financial statements

- -    The Quadrangles Village Apartments, Americana Lakewood Apartments and Other
     Property Dispositions. On June 24, 1998, the Company sold Quadrangles
     Village Apartments, a 510-unit apartment building located in Tempe, Arizona
     for approximately $26,500,000. On January 9, 1998, the Company consummated
     the sale of a 300-unit multi-family residential property known as Americana
     Lakewood Apartments located in the metropolitan Denver area for a gross
     sales price of $15,066,000. During 1997, the Company also sold three other
     directly owned and one indirectly owned multi-family residential properties
     (Timberleaf, Sedona, International and Emerald Point).

- -    The Szeles Portfolio. On July 30, 1998, the Operating Partnership acquired
     a portfolio consisting of five Class A office buildings located in
     Pennsylvania totaling approximately 385,000 square feet for a purchase
     price of $40,528,000, including closing costs.

- -    The ASW Property. On August 7, 1998, the Operating Partnership acquired an
     industrial building which totals 255,000 square feet, located in Green,
     Ohio for a purchase price of $7,858,000, including closing costs.

- -    The Pioneer Portfolio. In August 1998, the Operating Partnership will
     acquire 11 office buildings and one industrial facility located in Northern
     New York. The portfolio has aggregate rental space of approximately
     1,334,980 square feet including three office buildings (One Park Place and
     Waterfront I and II) which will be acquired by the Company in September
     1998 (One Park Place and Waterfront I) and December 1998 (Waterfront II).

All of the above acquisition transactions were accounted for in the proforma
financial statements using the purchase method of accounting.

This unaudited pro forma condensed consolidating financial information should be
read in conjunction with the historical financial statements of the Company for
the year ended December 31, 1997 and the Company's Quarterly Report on Form 10-Q
for the three months ended March 31, 1998 which are incorporated by reference.

To American Real Estate Investment Corporation:

We have audited the accompanying combined statement of revenue and certain
expenses of the Szeles Portfolio for the year ended December 31, 1997. This
financial statement is the responsibility of the Portfolios' management. Our
responsibility is to express an opinion on this financial statement based on our
audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the 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
purpose of complying with the rules and regulations of the Securities and
Exchange Commission for inclusion in a Current Report on Form 8-K of American
Real Estate Investment Corporation as described in Note 1, and is not intended
to be a complete presentation of the Portfolios' revenue and expenses.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenue and certain expenses of the Szeles Portfolio
for the year ended December 31, 1997 in conformity with generally accepted

                                SZELES PORTFOLIO

          NOTES TO COMBINED STATEMENTS OF REVENUE AND CERTAIN EXPENSES

                                DECEMBER 31, 1997

1.   BASIS OF PRESENTATION:

The combined statement of revenue and certain expenses reflects the operations
of the Szeles Portfolio (the "Portfolio"), which includes five office buildings:
two located in Wyomissing, Pennsylvania, two located in Mechanicsburg,
Pennsylvania, and one located in Allentown, Pennsylvania. The Portfolio is
expected to be acquired by American Real Estate Investment Corporation (the
"Company") from Szeles Real Estate Development Co. (four buildings) and Szeles
Investment Company (one building) (the "Sellers") in August of 1998. The
Properties have an aggregate net rentable area of approximately 385,457 square
feet (94% leased as of December 31, 1997). This combined statement of revenue
and certain expenses is to be included in the Company's current report on Form
8-K, 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 a 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 of revenue and expenses during the reporting period.
The ultimate results could differ from those estimates.

The combined 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 period 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 recognition in accordance with
generally accepted accounting principles. The aggregate rental revenue decrease
resulting from the straight-line adjustments for the year ended December 31,
1997, was $24,000 and for the three months ended March 31, 1998 was $11,630.

          Thereafter                        474,000


</TABLE>


Certain leases also include provisions requiring tenants to reimburse the
Portfolio for operating expenses, taxes and utilities when the current year
expenses exceed either a base year or the previous year's expense.

3.   RELATED PARTY TRANSACTIONS:

The Portfolio paid $29,000 for the year ended December 31, 1997 in lawn care 
services to an affiliate of the Sellers. No amounts were paid in the three 
month period ended March 31, 1998. These lawn care services are included in 
maintenance and other operating expenses in the accompanying statements.

The Portfolio paid $45,000 for the year ended December 31, 1997 in repairs 
and maintenance expenses to an affiliate of the Sellers. No amounts were paid 
in the three month period ended March 31, 1998. These repairs and maintenance 
expenses are included in maintenance and other operating expenses in the 
accompanying statements.

The Portfolio paid $32,000 in rent in 1997 to a related party as 
reimbursements for its costs to lease space in a building the affiliate 
owned. This rent expense in included in maintenance and other operating 
expenses in the accompanying statements.

 4.   SUBSEQUENT EVENTS:

American Real Estate Investment Corporation entered into a letter of intent 
on May 21, 1998 to purchase the Properties for a purchase price of 
approximately $40,528,000, including closing costs. This purchase price will 
be funded by the Company's revolving credit facility and cash proceeds 
received by the Company from the sale of Quadrangles Village Apartments, in 
June 1998.

rentable area of approximately 255,000 square feet (100% leased as of December

The accounting records of the Property are maintained on a modified cash basis.
Adjusting entries have been made to present the accompanying financial

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 Property.

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions

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

The results of the interim periods are not necessarily indicative of the results
for the full year.

consists of 11 properties in Syracuse, NY, one property in Buffalo, NY, one 
property in Greece, NY and one industrial property in Glenn Falls, NY. The 
Portfolio has an aggregate net rentable area of approximately 1,335,000 
square feet (93% leased as of December 31, 1997). The expected purchase price 
is approximately $132 million, including closing costs. This combined 
statement of revenue and certain expenses is to be included in the Company's 
Current Report on Form 8-K, as the above described transaction has been 
deemed significant pursuant to the rules and regulations of the Securities

The accounting records of the Portfolio are maintained on a 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, 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 of revenue and expenses during the reporting period.
The ultimate results could differ from those estimates.

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.

agrees to purchase from Seller, subject to the terms and conditions of this
Agreement, certain property consisting of the following:

                                          (i)  Improvements. All improvements

"Improvements") together with all appurtenances thereto including, without
limitation, all easements, rights-of-way, and other rights and benefits
belonging to, running with the owner of, or relating to the Improvements.

                                         (ii)  Personal Property. All fixtures,
equipment, all furniture, supplies, and other unattached items of personal
property located in or on, or used in connection with, the Improvements which
are listed on Exhibit A-2 to this Agreement; and all intangible personal
property listed in items 1, 2 and 3 to Exhibit B to the form of Bill of Sale
attached to this Agreement as Exhibit B-2 and used in the ownership, operation
or maintenance of the Improvements and the Land which is owned by Seller (all of
the foregoing items of property being collectively called "Personal Property").

                           (b)      Leasehold Estate. Seller agrees to sublease
to Buyer the Land in accordance with the terms and upon the conditions of a
Sublease Agreement to be negotiated by Seller and Buyer during the Inspection
Period (the "Sublease") or, at Buyer's option, by entry of a new ground lease
for the Land with the Ground Lessor. The estate to be created by the Sublease is
referred to in this Agreement as the "Leasehold Estate". Buyer shall advise
Seller whether Buyer shall elect to enter a new ground lease for the Land within
fifteen (15) days after the date of this Agreement.

                           (c)      Property. The Leasehold Estate and
Improvements are sometimes collectively called the "Real Property". The
Leasehold Estate, the Improvements and the Personal Property are sometimes
collectively called the "Property".

2.                Purchase Price. The purchase price (the "Purchase Price") 
for the Property, subject to adjustments as provided in this Agreement, shall be
Seven Million Six Hundred Thirty Thousand Dollars ($7,630,000), and shall be
paid as follows:

                           (a)      Upon expiration of the Inspection Period (as
defined below), One Hundred Thousand Dollars ($100,000) (such sum, plus all
interest which accrues thereon, is referred to in this Agreement as the
"Deposit") shall be paid by Buyer to First American Title Insurance Company
("Title Company"). 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 


                                       2

short-term United States Government obligations having a maturity date which
is not later than the Closing Date (as defined below).

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

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

4.                Closing. The closing of this transaction ("Closing") shall 
take place at the offices of Wolf, Block, Schorr and Solis-Cohen LLP, Twelfth
Floor Packard Building, 111 South Chestnut Street, Philadelphia, Pennsylvania

                           (a)      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 the Tenant Leases (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"). The premium for the Owner's Policy of
Title Insurance will be paid by Buyer.

Property to Buyer at Closing in accordance with the requirements of Section
5(a), Buyer shall have the right (i) of taking such title as Seller is able to
convey with abatement of the Purchase Price in the amount (fixed or
ascertainable) of any Monetary Liens (as defined below) on the Property, or (ii)
of terminating this Agreement.

                           (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. Prior to the
expiration of the Inspection Period, 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 ten business (10) days after 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. 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 ten (10) business days after 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.

                           (d) If Seller, without the right to do so and in the
default of its obligations under this Agreement fails to complete Closing, or
otherwise defaults under or breaches this Agreement, Buyer shall have the right,
at Buyer's sole election, either (A) to be returned the Deposit plus Buyer's
reimbursable costs as hereinafter defined or (B) to specific performance and
injunctive relief without monetary damages against Seller. Reimbursable costs
are defined to include the cost of all charges incurred by Buyer for searching
title, the cost of any plans, surveys and environmental studies ordered by
Buyer, all loan commitment fees paid by Buyer and all the fees, costs and
expenses reasonably incurred by Buyer in connection with the property and
Buyer's intended acquisition thereof, which in no event may exceed $35,000 in
the aggregate.

6.                Possession. Possession of the Property shall be given to 
Buyer at Closing, subject only to the Permitted Encumbrances and rights of
occupancy of the Tenants (as defined below) under the Tenant Leases by delivery

Buyer does not elect to terminate this Agreement pursuant to the provisions of
Section 10(b), and in such event, Buyer shall accept the Property at Closing as
damaged or destroyed by the Casualty and Buyer shall have the right to enter the
Real Property prior to Closing for the purpose of performing such repairs

                           (j)      Buyer's Exercise of Right to Terminate. If
Buyer desires to terminate this Agreement pursuant to any of the provisions of
this Agreement, Buyer shall do so by giving written notice of termination to
Seller. Upon any such termination, the Deposit shall be paid to Buyer (and each

shall have any further rights or obligations under this Agreement.

                           (k)      Survival. The representations, warranties
and agreements of Seller set forth in Sections 8 and 9 of this Agreement shall
survive Closing for a period of 12 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, 18, 19 and
20(j) this Agreement shall survive Closing. Except as otherwise provided in the

Buyer set forth in this Agreement shall not survive Closing and shall merge into

21.               Right of First Offer.

                           (a)      For the purpose of this Paragraph 21: the
term "Right of First Offer Parcel" shall mean all that certain tract of land
which is described by metes and bounds on Exhibit K hereto, situate in the City
of Green, Summit County, State of Ohio containing 23.557 acres; and the term
"Right of First Offer Term" shall mean the period of time commencing as of the
Closing Date, and terminating two (2) years after the Closing Date.

                           (b)     At Closing, Seller shall execute, acknowledge
and deliver to Buyer for recording, a separate right of first offer agreement,
prepared by Buyer, acceptable to Seller (and Seller agrees that the right of
first offer agreement shall be acceptable to it to the extent that its
provisions are substantially the same as those set forth below; and Seller
further agrees to be reasonable in granting or withholding its acceptance to the
right of first offer agreement), setting forth the following terms and
provisions but subject in all events to the qualifications set forth in Section
21(c) of this Agreement (the "Right of First Offer Agreement"):

                                  (i)        Seller shall not at any time during
the Right of First Offer Term sell or convey or agree to sell or convey all or
any portion of the Right of First Offer Parcel without first having complied
with the requirements of the Right of First Offer Agreement.

                                 (ii)        If Seller shall during the Right of
First Offer Term desire to sell or convey all or part of the Right of First
Offer Parcel, Seller shall deliver to Buyer written notice (the "First Offer
Notice") setting forth the price and other material terms on which Seller would
be willing to sell the Right of First Offer Parcel. Buyer shall have fifteen
(15) days from receipt of the First Offer Notice in which to elect to purchase
the Right of First Offer Parcel pursuant to the terms of the First Offer Notice.
If Buyer elects to purchase the Right of First Offer Parcel pursuant to the
terms of the First Offer Notice, Buyer shall give to Seller written notice
thereof ("Acceptance Notice") within said fifteen (15) day period and closing
shall be held 


                                       19
<PAGE>


within 90 days after the date of the Acceptance Notice, whereupon Seller shall
convey the Right of First Offer Parcel to Buyer. At closing, Seller shall
deliver to Buyer a special warranty deed, sufficient to convey to Buyer fee
simple title to the Right of First Offer Parcel free and clear of all liens,
restrictions and encumbrances, except for those subject to which the Right of
First Offer Parcel was to have been conveyed in accordance with the terms of the
First Offer Notice.

                                (iii)      In the event Buyer shall elect not to
purchase all or part of the Right of First Offer Parcel pursuant to a First
Offer Notice, Seller may thereafter sell the property which was the subject of
the First Offer Notice in accordance with the terms of the First Offer Notice.
If Seller has not sold that portion of the Right of First Offer Parcel which was
the subject of the First Offer Notice within six (6) months after the giving of
the First Offer Notice for a purchase price not less than 97% of the purchase
price specified in the First Offer Notice, Seller may not again seek to sell or
convey or agree to sell or convey such portion of the Right of First Offer
Parcel which was the subject of the First Offer Notice without again complying
with the terms of the Right of First Offer Agreement.

                                (iv)        To prevent Seller from defeating the
rights of Buyer pursuant to this Agreement, Seller agrees that Seller will not
during the Right of First Offer Term accept an offer to purchase all or any
portion of the Right of First Offer Parcel together with any other property.

                                (v)         The rights and obligations of Seller
and Buyer pursuant to this Agreement shall be binding upon Seller and its
successors and assigns, and shall inure to the benefit of Buyer and Buyer's
successors and assigns.

                           (c)      Notwithstanding anything contained in this
Section 21, Buyer's Right of First Offer shall not be applicable to and Seller
shall have no obligation under the Right of First Offer Agreement with respect
to the sale of improvements to be constructed on the Right of First Offer Parcel
to a third party user who intends to own such improvements and to occupy
substantially all of the floor area to be constructed within such improvements,
and which are to be constructed by Seller pursuant to a contract with such third
party user for the development and sale of such improvements.

this Agreement and continuing through the first anniversary of the Closing Date,

Seller hereunder, Seller shall, from time to time, upon reasonable advance
written notice from Buyer, provide to Buyer and its representatives: (i) access

statements in compliance with any and all of (a) Rule 3-05 or Rule 3-14 of

to Buyer; and (c) any registration statement, report or disclosure statement

letter, in form specified by, or otherwise satisfactory to the Accountants,
signed by the individual(s) responsible for Seller's financial reporting, as
prescribed by generally accepted auditing standards promulgated by the Auditing
Standards 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.

                  IN WITNESS WHEREOF, intending to be legally bound, the parties
have executed this Agreement as a sealed instrument as of the day and year first
above written.

         2.4      Purchase Price Supplement .

                  (a) In the event the principal tenant of Winchester Plaza 
                  Corporate Center, Aetna Life Insurance Company ("Aetna") 
                  timely exercises its option ("Renewal Option") to renew the 
                  term of its Existing Lease dated June 1, 1987 ("Aetna 
                  Existing Lease") for a term of 5 years (pursuant to the 
                  renewal option set forth in Section __ of the Aetna 
                  Existing Lease), Buyer shall pay to Seller, upon the 
                  commencement of the renewal term under the Aetna Existing 
                  Lease), the sum of $1,500,000 in immediately available U.S. 
                  funds by wire transfer ("Purchase Price Supplement").

                  (b) If Aetna does not timely exercise the Renewal Option 
                  and if Buyer and Aetna enter into a written agreement 
                  ("Aetna Lease Extension Agreement") pursuant to which, 
                  inter alia, Aetna and Buyer agree that Aetna shall continue 
                  in continuous possession of the demised premises it now 
                  occupies in Winchester Plaza after the expiration date of 
                  the current term of the Aetna Existing Lease, then Buyer 
                  shall pay to Seller, on the date on which Aetna commences 
                  to pay rent to Seller pursuant to the Aetna Lease Extension 
                  Agreement, a supplement to the Purchase Price ("Alternate 
                  Purchase Price Supplement").

                  (c) The Alternate Purchase Price Supplement shall be an 
                  amount equal to (i) the product of $300,000 times the 
                  lesser of (I) the number of years (full or fractional) in 
                  the fixed term of the Aetna Lease Extension Agreement and 
                  (II) five (5) less (ii) Seller's Share of Landlord 
                  Expenses. For the purpose of the calculation of the 
                  Alternate Purchase Price Supplement pursuant to the 
                  provisions of this subparagraph (c), if the premises 
                  demised to Aetna pursuant to the Aetna Lease Extension 
                  Agreement contains an area which is greater than or lesser 
                  than the premises demised to Aetna pursuant to the Aetna 
                  Existing Lease, then the figure of "$300,000" shall be 
                  adjusted to be the product of $300,000 multiplied by a 
                  fraction, the numerator of which fraction is the number of 
                  square feet demised to Aetna pursuant to the Aetna Lease 
                  Extension 

                                       3
<PAGE>

                  Agreement, and the denominator of which is the number of 
                  square feet leased to Aetna pursuant to the Aetna Existing 
                  Lease. If the Aetna Lease Extension Agreement provides for 
                  a fixed term of less than 5 years and grants to Aetna the 
                  option to renew the term of the Aetna Lease Extension 
                  Agreement and if Aetna exercises the renewal option, then 
                  on the date on which Aetna commences to pay rent for the 
                  option term, the Alternate Purchase Price Supplement shall 
                  be recomputed as if the renewal term had been included in 
                  the initial fixed term of the Aetna Lease Extension 
                  Agreement and any additional Alternate Purchase Price 
                  Supplements due by reason of such recomputation shall be 
                  paid by Buyer to Seller.

                  (d) The term "Landlord Expenses" shall mean the aggregate 
                  of all costs and expenses incurred by Buyer in connection 
                  with the Aetna Lease Extension Agreement for: brokerage 
                  fees and commissions; renovations and improvements to the 
                  premises demised to Aetna; and sums and contributions paid 
                  by Buyer to Aetna for leasehold improvements.

                  (e) The term "Seller's Share of Landlord Expenses" shall 
                  mean 50% of the amount by which the Landlord Expenses 
                  exceed an amount equal to the product of $1.00 times the 
                  area of the premises demised to Aetna pursuant to the Aetna 
                  Lease Extension Agreement, times the number of full and 
                  fractional years in the fixed term of the Aetna Lease 
                  Extension Agreement.

3.       CONDITION OF TITLE.

         3.1      Marketable Title.  Title to the Real Property shall be (i) 
                  good and marketable and free and clear of all liens, 
                  restrictions, easements, claims or liens by contractors, 
                  subcontractors, mechanics and materialmen, leases and 
                  tenancies and other title objections except for (a) the 
                  leases set forth on Exhibit "C" (the "Existing Leases"),(b) 
                  the lien of real estate taxes for 1998 not yet due and 
                  payable, and (c) such exceptions as are agreed to by Buyer 
                  in writing (the "Permitted Exceptions"); and (ii) insurable 
                  as aforesaid at 

                                       4
<PAGE>

                  ordinary rates by the Title Company pursuant to an ALTA 
                  Owner's Policy of Title Insurance (Form B -1970).

         3.2      Failure of Title.  Prior to the expiration of the 
                  Inspection Period, Buyer shall notify Seller as to the 
                  existence and nature of any matters which Buyer asserts 
                  constitute a failure of title as described in Section 3.1 
                  of this Agreement.  Any covenant, agreement, restriction, 
                  easement or other matter of record as of the date of this 
                  Agreement which is not the subject of a notice from Buyer 
                  to Seller pursuant to the preceding sentence shall be a 
                  Permitted Exception.  If title to the Real Property cannot 
                  be conveyed to Buyer at Closing in accordance with the 
                  requirements of this Agreement, then Buyer shall have the 
                  option of (i) taking such title as Seller can convey, the 
                  unfulfilled condition shall be deemed waived and there 
                  shall be no abatement of the Purchase Price, except that 
                  Buyer may apply so much of the Purchase Price as is 
                  necessary to the payment of monetary liens against the Real 
                  Property in an ascertainable amount which Seller has not 
                  otherwise paid or provided for; or (ii) terminating Buyer's 
                  obligations under this Agreement, at which time Seller 
                  shall cause Escrow Agent to return the Earnest Money 
                  Deposit to Buyer.  In the event Buyer terminates its 
                  obligations pursuant to subsection (ii) above, there shall 
                  be no further liability or obligation on the part of either 
                  of the parties hereto except for Seller's obligation to 
                  cause the Earnest Money Deposit to be returned to Buyer 
                  whereupon this Agreement shall become null and void.

         3.3      Seller is aware of an existing cross-easement agreement, as 
                  amended ("Cross-Easement"), which benefits and burdens 
                  Corporate Center 15 and the real property adjoining it at 
                  4910 Ritter Road ("Shelley's Point") owned by Szeles 
                  Building and Leasing Company. Notwithstanding Section 3.1 
                  and so long as doing so does not cause a violation of any 
                  land development ordinance or regulation at Corporate 
                  Center 15, Seller shall have the right to modify the 
                  provisions of the Cross-Easement prior to Closing so that 
                  (i) the total number of existing parking spaces available 
                  to Shelley's Point on the property of Corporate Center 15 
                  shall be reduced from twenty-three (23) to fourteen (14) to 
                  be chosen by Seller from among the existing parking spaces 
                  under the Cross-Easement and (ii) such parking spaces shall 
                  be dedicated to the exclusive use of Shelley's Point.

4.       INSPECTION MATTERS.

         4.1      Seller's Documents.  To the extent Seller has not 
                  previously done so, Seller shall, within five (5) days 
                  following the execution of this Agreement by both parties, 
                  make available to Buyer for inspection, true, correct and 
                  complete copies in all material respects of the documents 
                  relating to the 

                                       5

                  operation and approvals of the Properties in Seller's 
                  possession as set forth in Exhibit "E" (the "Seller's 
                  Documents"). Buyer acknowledges that, as of the date of 
                  Buyer's execution of this Agreement, Seller has complied 
                  with the requirements of this Section 4.1 except for those 
                  Seller's Documents set forth in Exhibit "E-1".

         4.2      Inspection of the Properties.

                  4.2.1    Buyer, its representatives, agents, and consultants
                           shall have the right to conduct such engineering,
                           environmental and other studies and inspections of
                           the physical condition of the Properties as Buyer, in
                           its absolute discretion, deems necessary or
                           appropriate through July 7, 1998, or such earlier
                           date as selected by the Buyer (the "Inspection
                           Period"). Such studies and inspections shall be at
                           Buyer's sole cost and expense. Buyer's investigations
                           during the Inspection Period are subject to the
                           provisions of Section 4.2.3 hereof.

                  4.2.2    During the Inspection Period, Buyer, at its sole cost
                           and expense, shall have the right to inspect, at the
                           address of Seller, all of Seller's books and records
                           which pertain to the maintenance and operation of the
                           Properties for calendar years 1997 and 1998,
                           provided, however, Buyer shall not have access to
                           books and records of Seller which are of a
                           proprietary nature and which do not pertain in a
                           material way to the maintenance or operation of the
                           Properties.

                  4.2.3    In conducting its inspections and studies of the
                           Properties as authorized by this Agreement, Buyer
                           shall (i) not materially disturb or interfere with
                           the operation, management or use of the Properties by
                           Seller, Seller's agents, any tenant of the Properties
                           or by any of such tenant's customers, invitees or
                           guests and (ii) not materially damage or affect the
                           physical structure of the Properties. Buyer covenants
                           and agrees to return the Properties to the same
                           condition as existed prior to such inspections and
                           studies.

                  4.2.4    At any time at or prior to the expiration of the
                           Inspection Period, Buyer may terminate this Agreement

                           shall be prorated as of the Closing Date. Uncollected

                           due landlord under the Existing Leases shall not be
                           prorated at the time of Closing, but Buyer shall
                           collect the same on Seller's behalf and tender the
                           same to Seller upon receipt. Notwithstanding the
                           foregoing, if the Closing Date occurs after the tenth
                           day of a calendar month and if as of the Closing Date

                           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 and Buyer shall use its best efforts to
                           collect the Delinquent Installment from the Tenant.

                           the Closing Date shall be retained by Buyer and
                           applied first on account of sums then currently due
                           and payable, and the balance shall be divided between
                           Seller and Buyer on a prorated basis reflecting the
                           respective periods of ownership of the Properties by
                           Seller and Buyer. Notwithstanding the foregoing,

                           operating expenses incurred by Seller prior to the
                           Closing Date, shall be applied by Buyer on account of
                           such operating expenses and reimbursed to Seller upon
                           receipt by Buyer. In the event any Existing Lease has
                           been terminated, or the tenant thereunder has vacated
                           and abandoned the demised premises and sums remain
                           payable to Seller under the Existing Lease for
                           periods up to and including the Closing Date, Seller
                           shall have the right to pursue such tenant for any
                           sums due Seller by all lawful means. Seller shall
                           transfer to Buyer at Closing all tenant security
                           deposits and all interest accrued thereon and all
                           pre-paid rentals held by Seller under the Existing
                           Leases.

                  5.3.2    Real Estate Taxes. Real Estate Taxes shall be 
                           prorated as of the Closing Date in accordance with 
                           the fiscal year of the taxing authority. Seller 
                           shall pay all real estate taxes attributable to the 
                           Properties to (but not including) the Closing Date. 
                           If the real estate tax rate and assessments have not 
                           been set for the year in which the

                           Closing occurs, then the proration of such taxes
                           shall be based upon the rate and assessments for the
                           preceding tax year, and such proration shall be
                           adjusted in cash between Seller and Buyer upon
                           presentation of written evidence that the actual
                           taxes paid for the year in which the Closing occurs
                           differ from the amounts used at Closing and in
                           accordance with the provisions of Section 5.3.9

                           of Buyer under this Agreement, at law or in equity,
                           including, without limitation, the right to specific
                           performance and injunctive relief.


                  9.2      Seller. If Buyer, in default of its obligations under
                           this Agreement fails to consummate the Transaction
                           pursuant to the terms and conditions of this
                           Agreement, then Seller may elect as Seller's sole
                           option hereunder to terminate this Agreement and to
                           receive the Earnest Money Deposit as liquidated
                           damages and thereafter Seller and Buyer shall have no
                           further obligations or liabilities one to the other

                           Money Deposit as "liquidated damages" is agreed to,
                           due to the difficulty, inconvenience and uncertainty
                           of ascertaining actual damages for such breach by
                           Buyer and the parties agree that the same is a
                           reasonable and fair estimate of damages. Seller and
                           Buyer agree that the liquidated damages clause
                           contained herein is reasonable and enforceable and
                           neither party shall challenge the liquidated damages
                           provision hereof as unenforceable. 

10.               RISK OF LOSS.

                  10.1     Casualty. If any Building or any part thereof is
                           damaged by any casualty prior to Closing, Seller
                           shall immediately notify Buyer in writing of the same
                           ("Casualty Notice") and if the cost of repairing such
                           damage is:

                                    ($125,000.00), then Seller shall notify
                                    Buyer as to such damage, and Buyer shall
                                    elect whether the Seller shall repair such
                                    damage, and if so, Seller shall restore the
                                    damaged Building as promptly as is
                                    reasonably possible to as good condition as
                                    existed immediately prior to such casualty
                                    and in such event Closing shall be deferred

                           the other, and the Earnest Money Deposit shall be

                  12.14    Waiver of Tender of Deed and Purchase Monies. The
                           tender of executed deeds by Seller and the tender by

                           nothing in this Agreement shall be construed as a
                           waiver of Seller's obligation to deliver the deeds
                           and/or of the concurrent obligation of Buyer to pay

                           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.

                           thereafter shall survive to the extent that Buyer
                           shall have given to Seller written notice of a breach
                           thereof. The obligations of Seller and Buyer pursuant

                           refusal]; and the term "Term" shall mean the period
                           of time commencing as of the date of this Agreement
                           and ending eighteen months after the date of this
                           Agreement.

                                    (ii) Seller agrees not to sell the Subject
                           Property during the Term except in strict compliance

                           contemplated by this Paragraph 15.

                                    (iii) If, at any time during the Term,
                           Seller desires to sell the Property, Seller shall
                           give to Buyer written notice ("Sale Notice")
                           specifying the terms and conditions pursuant to which
                           Seller desires to sell the Subject Property. The Sale
                           Notice shall contain, at a minimum, the purchase
                           price, the terms on which the purchase price is
                           payable, the condition pursuant to which title to the

                           date (which closing date shall be not less than sixty
                           (60) days after the date on which Seller delivers the
                           Sale Notice to Buyer). Buyer shall have the right to
                           purchase the Subject Property pursuant to the terms
                           and provisions of the Sale Notice by giving to Seller
                           written notice ("Acceptance Notice") that Buyer
                           intends to purchase the Subject Property pursuant to
                           the terms and provisions of the Sale Notice. If Buyer
                           gives the Acceptance Notice to Seller, Buyer shall
                           thereafter purchase the Subject Property from Seller
                           upon the terms set forth in the Sale Notice. If Buyer
                           has not given to Seller an Acceptance Notice within
                           ten days after delivery to Buyer of the Sale Notice,
                           then Seller shall have the right (for a period not
                           exceeding 180 days) to sell the Subject Property to
                           any purchaser pursuant to the terms and provisions of
                           the Sale Notice including a purchase price variance
                           of up to three percent of the purchase price set
                           forth in the Sale Notice (or pursuant to terms and
                           provisions which are, in the aggregate, more
                           favorable to Seller than the terms and provisions
                           contained in the Sale Notice). If Seller gives to
                           Buyer a Sale Notice and Buyer does not timely give to
                           Seller an Acceptance Notice, and if Seller does not
                           thereafter (within 180 days) sell the Subject
                           Property in accordance with the terms and provisions
                           of the Sale Notice, then the rights of Buyer pursuant
                           to this Paragraph shall continue in full force and
                           effect.

                                    (iv) If, during the Term, Seller receives a
                           written offer ("Unsolicited Offer") from an unrelated
                           third party ("Offeror") setting forth the terms and
                           provisions pursuant to which such Offeror desires to
                           purchase the Subject Property (such terms and
                           provisions to contain, at a minimum, the terms and
                           provisions set forth above to be contained in a Sale
                           Notice) and if Seller desires to accept the
                           Unsolicited Offer, Seller shall give to Buyer a copy
                           of the Unsolicited Offer. Buyer shall have the right
                           to purchase the Subject Property pursuant to the
                           terms and provisions of the Unsolicited Offer by
                           giving to Seller written notice ("Acceptance Notice")
                           that Buyer intends to purchase the Subject Property
                           pursuant to the provisions of the Unsolicited Offer.
                           If Buyer gives the Acceptance Notice to Seller, Buyer
                           shall thereafter purchase the Subject Property from
                           Seller upon the terms set forth in the Unsolicited
                           Offer. If Buyer has not given to Seller an Acceptance
                           Notice within ten days after delivery to Buyer of the
                           Unsolicited Offer, then Seller shall have the right
                           (for a period not exceeding 180 days) to sell the
                           Subject Property to the Offeror pursuant to the terms
                           and provisions of the Unsolicited Offer (or pursuant
                           to the terms and provisions which are, in the
                           aggregate, more favorable to Seller than the terms
                           and provisions contained in the Unsolicited Offer).
                           If Seller gives to Buyer an Unsolicited Offer and
                           Buyer does not timely give to Seller an Acceptance
                           Notice, and if Seller does not thereafter (within 180
                           days) sell the Subject Property to the Offeror in
                           accordance with the terms and provisions of the Sale
                           Notice, then the rights of Buyer pursuant to this
                           Paragraph shall continue in full force and effect.

                                    (v) Anything to the contrary notwithstanding
                           in this subparagraph 15(a), Seller shall have the
                           right to grant to any tenant or prospective tenant
                           (unrelated to Seller) of the Subject Property, as a
                           material inducement to remain as a tenant at the
                           Subject Property or to enter into a lease with Seller
                           for space in the Subject Property a right of first
                           offer/right of first refusal upon the same terms and
                           provisions as those granted to Buyer herein ("Tenant
                           Right"). Such Tenant Right shall be superior to the
                           Right of First Offer/Right of First Refusal granted
                           herein to Buyer, but if such Tenant Right is not
                           exercised by the tenant, Buyer's Right of First
                           Offer/Right of First Refusal shall not be
                           extinguished.

                           (b)      Noncompetition.

                           Property is occupied by tenants pursuant to
                           arm's-length leases with Seller.
                            For the purposes of this subparagraph (b), the term

                                    (ii) Seller agrees that during the
                           Noncompetition Term, Seller will not negotiate to

                           Notwithstanding the foregoing, during the
                           Noncompetition Term, Seller shall be able to

                  3B(iii)(a) and Section 3B(iv)(a), respectively, equal to the
                  Additional Cash Amount allocable to each Property and
                  Additional Property (pursuant to a revised Schedule 3B(i) to
                  be delivered by Contributor concurrently with the Cash
                  Notice), divided by $16.50. Whether or not a Cash Notice is

                           later than 15 business days prior to the Second
                           Closing Date electing to increase the Waterfront II

                           II and the Option Increase allocable to One City
                           Centre and/or Three City Centre (pursuant to a
                           revised Schedule 3B(i) to be delivered by Contributor
                           concurrently with an Increase Notice), divided by
                           $16.50; provided, however, that the sum of the Second
                           Increase and the Option Increase may not exceed
                           $500,000 in the aggregate, and the sum of the
                           Additional Cash Amount, the Second Increase and the
                           Option Increase may not exceed $19,289,780 in the
                           aggregate.

         The Waterfront II Consideration, One City Centre Consideration, if any,
         and Three City Centre Consideration, if any, are hereinafter sometimes
         referred to individually and collectively as the "Additional
         Consideration." If the calculation of the Contribution Consideration,
         or the Additional Consideration, as the case may be, in accordance with
         the foregoing provisions would result in a fraction of an OP Unit being
         delivered to a Contributor, then such fraction shall be rounded to the
         nearest whole number. The Properties are to be contributed to Acquiror
         (directly or indirectly) subject to all Existing Indebtedness, which is
         not to exceed the Cash Amount; minus the amount reimbursed to
         Contributor pursuant to Section 3M relating to the Properties; minus
         the amount of Existing Indebtedness which any Properties which become
         Deleted Properties (as defined below), Contributor Deleted Properties
         (as defined below) or Eliminated Properties (as defined below) are
         subject to. Waterfront II is to be contributed to Acquiror (directly or
         indirectly) subject to the Waterfront II Indebtedness, which is not to
         exceed the Waterfront II Cash Amount minus the amount reimbursed to
         Contributor pursuant to Section 3M relating to Waterfront II. One City
         Centre is to be contributed to Acquiror (directly or indirectly)
         subject to the One City Centre Indebtedness, which is not to exceed the
         One City Centre Cash Amount; minus the amount reimbursed to Contributor
         pursuant to Section 3M relating to One City Centre. Three City Centre
         is to be contributed to Acquiror (directly or indirectly) subject to
         the Three City Centre Indebtedness, which is not to exceed the Three
         City Centre Cash Amount; minus the amount reimbursed to Contributor
         pursuant to Section 3M relating to Three City Centre. The Contribution
         Consideration and Additional Consideration are allocated amongst (i)
         the Properties and Additional Properties in proportion to each
         Property's and Additional Property's aggregate value, as set forth in
         Schedule 3B(i), and (ii) the Management Contracts in proportion to each
         Management Contract's aggregate value, as set forth in Schedule 3B(ii).

                  C. Issuance of OP Units. Units of limited partnership interest
in Acquiror (the "OP Units") shall be issued at the Closing (with respect to the
Properties), the Second Closing (with respect to Waterfront II) or the Option
Closing (with respect to One City Centre and Three City Centre) in the names of
and delivered to those recipients identified by Contributor to Acquiror who have
executed and delivered to Acquiror at Closing, the Second Closing or the Option
Closing, as the case may be, the OP Unit Recipient Agreement (as defined below)
(the "OP Unit Recipients"). At least 10 business days prior to the Closing, the
Second Closing or the Option Closing, as the case may be, Contributor shall
deliver to Acquiror Exhibit G to be attached hereto, listing such OP Unit
Recipients and the number of OP Units allocated to each of them. With respect to
the first Partnership Record Date (as defined below) on or after the Closing,
the Second Closing and the Option Closing, as the case may be, for distributions
by Acquiror as contemplated by the Partnership Agreement (as defined below),
distributions payable with respect to the OP Units issued pursuant to this
Agreement shall be made to the OP Unit Recipients on a pro rata basis based upon
the number of days during the calendar quarter preceding such Partnership Record
Date that the OP Unit Recipients held such OP Units. "Partnership Record Date"
shall mean the record date established by the REIT, as general partner of
Acquiror, for any particular distribution of Net Operating Cash Flow (as defined
in and pursuant to the Partnership Agreement). The REIT hereby covenants and
agrees that the first Partnership Record Date on or after the Closing, the
Second Closing and the Option Closing, as the case 

                                       8


<PAGE>

may be, will be the same as the record date for distributions to the
stockholders of the REIT.

                  After the applicable Lock-up Period (as defined below) the OP
Units issued at the Closing, the Second Closing and the Option Closing, as the
case may be, 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 (subject to the anti-dilution provisions
set forth in the Partnership Agreement), 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 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. The REIT agrees that it will use its
commercially reasonable efforts to obtain such stockholder approval, including
presenting such matter, with management's endorsement, to the REIT's
stockholders at the next annual or special meeting of stockholders following the
Closing, and to present such matter at each subsequent meeting for at least
three years from the Closing Date if the necessary stockholder approval is not
obtained. If such stockholder approval is not obtained by the end of the Lock-Up
Period (as defined below), each OP Unit Recipient may exercise its Conversion
Right (as defined in the Partnership Agreement) for those OP Units which are no
longer restricted pursuant to Section 3E, and shall be entitled to receive cash,
but not Conversion Shares, pursuant to the Partnership Agreement (without regard
to the second sentence in Section 12.6 of the Partnership Agreement).

                  D. Transfer Restrictions. Each OP Unit Recipient, by his
execution and delivery of the OP Unit Recipient Agreement, agrees that he may
only offer, sell, offer or contract to sell, transfer, assign, grant any option
for the sale of, 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 OP Unit Recipient
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. The OP
Unit Recipient Agreement shall reflect the foregoing.

                  E. Lock-Up Period. Each OP Unit Recipient agrees by his
execution of the OP Unit Recipient Agreement that for a period of twelve (12)
months following the Closing (the "First Anniversary") with respect to OP Units
issued at the Closing, and for a period of six (6) months following the Second
Closing or Option Closing (or until the First Anniversary, whichever is later)
with respect to OP Units issued at the Second Closing or Option Closing (each as
applicable, 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), or effect or seek to effect a Transfer of
any or all of the OP Units delivered to the OP Unit Recipient at the Closing,
the Second Closing or the Option Closing, respectively; provided that the
foregoing transfer restrictions shall not apply to (i) pledges of, or
encumbrances on, OP Units in favor of institutional lenders or other financial
institutions with assets in excess of Five Billion Dollars, provided that such
OP Unit Recipient shall promptly notify Acquiror of such pledge of, or
encumbrance on, such OP Units, stating the details thereof, or (ii) Transfers
made, subject to the restrictions hereof, 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 


                                       9

<PAGE>

more than twenty-five percent (25%) of the OP Units delivered to such OP Unit
Recipient at the Closing, the Second Closing or the Option Closing, as the case
may be, 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 (plus any OP Units or
Conversion Shares which could have previously been sold pursuant to the
provisions hereof but were not) may be sold in each three-month period
thereafter (so that all OP Units and Conversion Shares may be sold after the
ninth (9th) month after the Lock-Up Period following, as applicable, the Closing
Date, with respect to OP Units issued at the Closing, the Second Closing Date,
with respect to OP Units issued at the Second Closing, or the Option Closing
Date, with respect to OP Units issued at the Option Closing). Notwithstanding
the foregoing, if all of the OP Units received by an OP Unit Recipient, directly
or indirectly, at the Closing, Second Closing and Option Closing is less than
30,000 OP Units, then such OP Unit Recipient shall be entitled to sell all of
his remaining OP Units at any time following the expiration of the Lock-Up
Period. The term "Permitted Transferee" with respect to any OP Unit Recipient
shall mean such recipient's spouse; a parent or lineal descendant (including an
adopted child) of a parent, or the parent or 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; 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; other OP Unit Recipients or Permitted Transferees thereof;
any direct or indirect equity owners of an OP Unit Recipient; and any public
charity, private foundation or charitable institution as defined in Section
501(c)(3) of the Internal Revenue Code of 1986, as amended (the "Code"), but
only in each case, 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. The OP Unit Recipient
Agreement shall reflect the foregoing. Notwithstanding the provisions of Section
9.3(a) of the Partnership Agreement, by its execution and delivery of this
Agreement, the REIT, as general partner of Acquiror, hereby consents to
Transfers of OP Units during and after the Lock-Up Period as permitted in this
Agreement during the Lock-Up Period, subject to the provisions of Section
9.3(b)-(d) and Section 9.6 of the Partnership Agreement.

                  F. Right of First Refusal/First Offer on Sale of OP Units.
Each OP Unit Recipient will agree that Acquiror shall have a right of first
refusal with respect to unsolicited offers to purchase OP Units from such OP
Unit Recipient and a right of first offer with respect to OP Units that such OP
Unit Recipient seeks to sell (other than Transfers to Permitted Transferees), as
provided in an agreement to be delivered by each OP Unit Recipient at Closing,
the Second Closing or the Option Closing, as the case may be, substantially in
the form of Exhibit H attached hereto (the "OP Unit Recipient Agreement"). Any
Permitted Transferee will be required to agree to be bound by the provisions of
this Section 3F.

                  G. Right of First Offer/First Refusal on Development, 
Sale and Acquisition of Buildings.

                        (i) Development Projects. During the period from and
         after the Closing Date through and continuing up to and including the
         fifth (5th) anniversary thereof (the "Option Period"), Acquiror shall
         have a continuing right of first offer on development opportunities of
         the Falcone Group (as defined below) in the Standard Metropolitan
         Statistical Areas of Albany, Buffalo, Rochester and Syracuse in the
         State of New York (the "SMSAs") for the construction of office or
         industrial buildings (excluding medical 


                                       10


<PAGE>

         office buildings) on undeveloped land or the demolition of existing
         improvements and the construction of office or industrial buildings
         (excluding medical office buildings) on a parcel of land (each, a
         "Development Project") in accordance with the following procedures: If
         during the Option Period the Falcone Group desires to develop a
         Development Project in any of the SMSAs and desires to use a
         third-party equity capital partner (other than key executives or
         employees of Pioneer Development Company, LLC making minority
         investments)(a "Development Partner"), the Falcone Group shall provide
         written notice (a "Development Offer Notice") to Acquiror (i)
         specifying the terms and conditions upon which the Falcone Group would
         be willing to develop such Development Project with a Development
         Partner including the terms of payment or capital contributions, as the
         case may be, the identity of the Development Project and other material
         terms and conditions (collectively, the "Development Offer Terms"); and
         (ii) offering Acquiror the opportunity to become the Development
         Partner for such Development Project upon the Development Offer Terms.
         Acquiror or its nominee shall be entitled, for a period of fifteen (15)
         days after the date of receipt of a Development Offer Notice (the
         "Development Exercise Period"), to exercise its rights hereunder by
         written notice to the Falcone Group (a "Development Acceptance Notice")
         to become a Development Partner for the Development Project, in
         accordance with the Development Offer Terms. If during the Development
         Exercise Period Acquiror delivers a Development Acceptance Notice to
         the Falcone Group, Acquiror and the Falcone Group shall use
         commercially reasonable efforts to enter into appropriate documentation
         for Acquiror to become a Development Partner upon the Development Offer
         Terms with regard to the Development Project within sixty (60) days
         after the date of receipt of the Development Offer Notice by Acquiror.
         If (i) Acquiror fails to timely deliver a Development Acceptance Notice
         to the Falcone Group, (ii) Acquiror notifies the Falcone Group that it
         does not desire to become a Development Partner, or (iii) a Development
         Acceptance Notice is timely given but after all commercially reasonable
         efforts have been made by the Falcone Group, appropriate documentation
         is not entered into within the sixty (60) day period noted above, then
         the Falcone Group shall have the right to seek and enter into an
         agreement with another Development Partner for the Development Project
         upon terms which would not be materially more favorable to Acquiror
         than the Development Offer Terms; provided, however, that if the
         Falcone Group does not enter into a binding contract for a third-party
         to become a Development Partner for such Development Project within 180
         days of the later of (x) the expiration of the Development Exercise
         Period (e.g. if Acquiror failed to timely exercise, or declined its
         right to exercise, its option hereunder) or (y) the end of the
         applicable time period relating to clause (iii) above, or the Falcone
         Group desires to offer a third-party the right to become a Development
         Partner for such Development Project on terms which would be materially
         more favorable to Acquiror than the Development Offer Terms, then
         Acquiror shall again have its right of first offer to become a
         Development Partner for the development of the Development Project as
         set forth in this paragraph, and the Falcone Group and Acquiror shall
         again comply with the requirements hereof; provided, however, that if
         the Falcone Group desires to enter into an agreement with another
         Development Partner on terms which would be materially more favorable
         to Acquiror than the Development Offer Terms, Acquiror shall only have
         five (5) calendar days after receipt of the revised Development Offer
         Terms to deliver the Development Acceptance Notice. Notwithstanding the
         foregoing, this subsection (i) shall not apply to third-party
         financing.

                       (ii)         Sale Projects.
                                    --------------

                           (a) During the Option Period, if the Falcone Group
                  shall decide to sell (whether by transfer of fee simple
                  interest or a leasehold interest, sale of an interest in an
                  entity which owns an interest in, an installment sale, or
                  otherwise) one or more office or industrial buildings and
                  related land and facilities (excluding medical office
                  buildings)

                  Group and located in any of the SMSAs (each, an "Offer
                  Project"), then prior to offering any Offer Project to a
                  third-party purchaser, the Falcone Group shall provide written
                  notice (an "Offer Project Notice") to Acquiror (i) specifying
                  the purchase price, terms of payment, identity of the Offer
                  Project and other material terms and conditions which the
                  Falcone Group proposes for the sale of the Offer Project
                  (collectively, the "Offer Project Terms") and (ii) offering to
                  sell to Acquiror the Offer Project on the Offer Project Terms.
                  Acquiror or its nominee will have the option, to be exercised
                  by written notice (an "Offer Project Acceptance Notice") to
                  the Falcone Group within fifteen (15) days after Acquiror's
                  receipt of the Offer Project Notice (the "Offer Exercise
                  Period") to accept the Offer Project Terms. The Falcone Group
                  and Acquiror shall use commercially reasonable efforts to
                  enter into a purchase and sale agreement relating to the Offer
                  Project upon the Offer Project Terms within sixty (60) days
                  after receipt by Acquiror of the Offer Project Notice and the
                  Falcone Group and Acquiror shall consummate the transaction
                  contemplated by the Offer Project Notice within the time
                  period specified in such agreement. If (i) Acquiror fails to
                  timely deliver the Offer Project Acceptance Notice to the
                  Falcone Group, (ii) Acquiror notifies the Falcone Group that
                  it does not desire to accept the Offer Project Terms, (iii) an
                  Offer Project Acceptance Notice is timely given but after all
                  commercially reasonable efforts have been made by the Falcone
                  Group, a purchase and sale agreement is not entered into
                  within the sixty (60) day period noted above, or (iv) the
                  transaction contemplated by the Offer Project Notice is not
                  consummated within time period set forth in the purchase and
                  sale agreement, unless such consummation is delayed for
                  reasons beyond the reasonable control of Acquiror, then the
                  Falcone Group shall have the right to sell the Offer Project
                  to a third-party purchaser upon terms which would not be
                  materially more favorable to Acquiror than the Offer Project
                  Terms; provided, however, if a binding agreement with regard
                  to the Offer Project is not entered into by the Falcone Group
                  and a third-party purchaser within 180 days of the later of
                  (x) the expiration of the Offer Exercise Period (if Acquiror
                  failed to timely exercise, or declined its right to exercise,
                  its option hereunder) or (y) the end of the applicable time
                  period relating to clauses (iii) or (iv) above, or the Falcone
                  Group desires to offer to sell the Offer Project to a
                  third-party purchaser on terms which would be materially more
                  favorable to Acquiror than the Offer Project Terms, then the
                  Falcone Group shall, prior to offering the Offer Project to a
                  third-party, again be obligated to offer to sell to Acquiror
                  the Offer Project by delivering a revised Offer Project Notice
                  to Acquiror reflecting the revised Offer Project Terms the
                  Falcone Group would be willing to accept for the Offer Project
                  and the Falcone Group and Acquiror shall again comply with the
                  requirements hereof; provided, however, that if the Falcone
                  Group desires to offer to sell the Offer Project to a
                  third-party purchaser on terms which would be materially more
                  favorable to Acquiror than the Offer Project Terms, Acquiror
                  shall only have five (5) calendar days after receipt of the
                  revised Offer Project Terms to deliver the Offer Project
                  Acceptance.

                           (b) During the Option Period, if the Falcone Group
                  receives from a third-party an unsolicited offer to purchase
                  (whether by transfer of fee simple interest or a leasehold
                  interest, an interest in an entity which owns an interest in,
                  an installment sale, or otherwise) one or more office or
                  industrial buildings and/or related land and facilities
                  (excluding medical office buildings) directly or indirectly
                  owned or controlled by the Falcone Group and located in any of
                  the SMSAs (each, a "Refusal Project"), then prior to accepting
                  such unsolicited offer, the Falcone Group shall provide
                  written notice (a "Refusal Project Notice") to Acquiror
                  specifying (i) the purchase price, terms of payment, identity
                  of the

                  offered to the Falcone Group relating to the sale of the
                  Refusal Project (collectively, the "Refusal Project Terms")
                  and (ii) offering to sell to Acquiror the Refusal Project on
                  the Refusal Project Terms. Acquiror or its nominee will have
                  the option, to be exercised by written notice (a "Refusal
                  Project Acceptance Notice") to the Falcone Group within
                  fifteen (15) days after Acquiror's receipt of the Refusal
                  Project Notice (the "Refusal Exercise Period") to accept the
                  Refusal Project Terms. The Falcone Group and Acquiror shall
                  use commercially reasonable efforts to enter into a purchase
                  and sale agreement relating to the Refusal Project upon the
                  Refusal Project Terms within sixty (60) days after receipt by
                  Acquiror of the Refusal Project Notice and the Falcone Group
                  and Acquiror shall consummate the transaction contemplated by
                  the Refusal Project Notice within the time period specified in
                  such agreement. If (i) Acquiror fails to timely deliver the
                  Refusal Project Acceptance Notice to the Falcone Group, (ii)
                  Acquiror notifies the Falcone Group that it does not desire to
                  accept the Refusal Project Terms, (iii) a Refusal Project
                  Acceptance Notice is timely given but after all commercially
                  reasonable efforts have been made by the Falcone Group, a
                  purchase and sale agreement is not entered into within the
                  sixty (60) day period noted above, or (iv) the transaction
                  contemplated by the Refusal Project Notice is not consummated
                  within the time period set forth in the purchase and sale
                  agreement, unless such consummation is delayed for reasons
                  beyond the reasonable control of Acquiror, then the Falcone
                  Group shall have the right to sell the Refusal Project on
                  terms which would not be materially more favorable to Acquiror
                  than the Refusal Project Terms to the third-party purchaser
                  which offered to buy the Refusal Project; provided, however,
                  if a binding agreement with regard to the Refusal Project is
                  not entered into by the Falcone Group and such third-party
                  purchaser within 180 days of the later of (x) the expiration
                  of the Refusal Exercise Period (if Acquiror failed to timely
                  exercise, or declined its right to exercise, its option
                  hereunder) or (y) the end of the applicable time period
                  relating to clauses (iii) or (iv) above, or the Falcone Group
                  desires to sell the Refusal Project to such third-party
                  offeror on terms which would be materially more favorable to
                  Acquiror than the Refusal Project Terms, then the Falcone
                  Group shall, prior to selling the Refusal Project to such
                  third-party, again be obligated to offer to sell to Acquiror
                  the Refusal Project by delivering a revised Refusal Project
                  Notice to Acquiror reflecting the revised Refusal Project
                  Terms the Falcone Group would be willing to accept for the
                  Refusal Project and the Falcone Group and Acquiror shall again
                  comply with the requirements hereof; provided, however, that
                  if the Falcone Group desires to offer to sell the Refusal
                  Project to a third-party purchaser on terms which would be
                  materially more favorable to Acquiror than the Refusal Project
                  Terms, Acquiror shall only have five (5) calendar days after
                  receipt of the revised Refusal Project Terms to deliver the
                  Refusal Project Acceptance.

                  This subsection (ii) of Section 3G shall not apply to any
                  Deleted Properties and shall apply to any Contributor Deleted
                  Properties. With respect to any Contributor Deleted
                  Properties, the rights of Acquiror in this subsection (ii) of
                  Section 3G shall be subject to the existing rights of partners
                  or required offerees of the Falcone Group which are contained
                  in the partnership agreement of the relevant Owner, and shall
                  not apply if the Falcone Group is a minority partner in an
                  Owner of a Contributor Deleted Property on the date of this
                  Agreement and the other partners in such Owner elect to sell
                  or otherwise dispose of such Contributor Deleted Property to a
                  third party.

                      (iii) Notwithstanding the foregoing right of first offer
         and right of first refusal,

         such rights shall not apply to Development Projects, Offer Projects or
         Refusal Projects in instances where the Falcone Group either receives
         bona fide offers from, or proposes to develop or acquire with,
         potential purchasers or potential developers who would also be, or
         whose affiliate would be, the sole tenant in the existing building(s)
         or the building(s) proposed to be built pursuant to such projects.

                           (a) During the Option Period, the Falcone Group shall
                  not, directly or indirectly, acquire, solicit, seek to acquire
                  or solicit, or otherwise pursue any opportunities to acquire
                  (whether by transfer of fee simple interest, a leasehold
                  interest or an interest in any entity owning any such
                  interest, an installment sale, or otherwise) any office or

                  medical office buildings) located in any of the SMSAs other
                  than for or on behalf of Acquiror.

                           (b) During the Option Period, if the Falcone Group
                  receives from a third-party an unsolicited offer to sell to
                  the Falcone Group (whether by transfer of fee simple interest,
                  a ground lease, an installment sale, or otherwise) one or more
                  office or industrial buildings and related land and facilities
                  (excluding medical office buildings) located in any of the
                  SMSAs, then the Falcone Group shall promptly provide written
                  notice to Acquiror of such offer and shall refer such
                  third-party offeror to Acquiror.

                        (v) The Falcone Group. The "Falcone Group" shall mean
         Michael J. Falcone and his spouse, Michael P. Falcone and his spouse,
         and lineal descendants of Michael J. Falcone and Michael P. Falcone
         (the "Falcone Family") and each entity that directly or indirectly,
         through one or more intermediaries, is controlled by the Falcone
         Family. For purposes of this definition, control of an entity means the
         power, direct or indirect, to direct or cause the direction of
         management and policies of such person or entity whether by contract or
         otherwise.

                       (vi) Confidentiality. Acquiror agrees to keep strictly
         confidential the terms and existence of any Development Project, Offer
         Project or Refusal Project unless and until it has been accepted by
         Acquiror.

                  H.       Tax Matters.
                           ------------
                        (i) No Property Disposition. (a) In the case of those
         Properties or Additional Properties set forth on Schedule 3H attached
         hereto, 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 (with respect to the Properties), the Second Closing (with
         respect to Waterfront II) or the Option Closing Date (with respect to
         One City Centre and Three City Centre), or (II) the sale or disposition
         in a taxable transaction, or conversion by each OP Unit Recipient who
         received OP Units in respect of such Property (or Additional Property,
         as the case may be) of OP Units representing 70% of the OP Units
         delivered to such OP Unit Recipient at the Closing, the Second Closing
         and the Option Closing in respect of such Property (or Additional 
         Property, as the case may be) (the "70% Condition"); and (b) in the 
         case of the remaining Properties, 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 (including, without limitation, by way of a deed in lieu of
         foreclosure, a foreclosure action, or an act of eminent domain) of any
         of the Properties or


                                       14
<PAGE>

         Additional Properties in a transaction that causes Contributor to 
         recognize taxable income in excess of "book" income under Section 
         704(c) of the Code with respect to such sale or other disposition 
         without the consent of the affected Contributor. Thereafter, 
         Acquiror shall use all commercially reasonable efforts in disposing
         of any of the Properties or Additional Properties during the period
         expiring on the earlier to occur of (x) the tenth (10th) anniversary 
         of the Closing Date (with respect to the Properties), the Second 
         Closing Date (with respect to Waterfront II) or the Option Closing
         Date (with respect to One City Centre and Three City Centre), or (y)
         the achievement of the 70% Condition, to structure such disposition
         as a transaction that will not result in a material gain to the 
         Contributors, whether by means of an exchange contemplated under
         Code Sections 351, 354, 355, 368, 721, 1031, 1033 or otherwise,
         provided that if such disposition were not so structured the affected
         Contributor would recognize taxable income in excess of "book" income
         with respect to such disposition.

                       (ii) Debt Maintenance and Guaranty Requirements. At
         Closing, or at any time subsequent thereto in accordance with the terms
         hereof, Acquiror will permit Contributor at Contributor's option to
         guarantee the "bottom" portion (i.e., the least risky portion) of
         available indebtedness of Acquiror or indemnify the REIT, Acquiror or
         any of their subsidiaries for liabilities in respect thereof. Subject
         to this Section 3H(ii), Acquiror agrees to maintain at all times an
         amount of indebtedness equal to $57,000,000 (reduced by the amount of
         indebtedness Contributor no longer requires due to the Additional Cash
         Amount) (the "Debt Amount") for only Contributor (as allocated by
         Contributor among Contributor) to guarantee (or indemnify the REIT,
         Acquiror or any of their subsidiaries for such indebtedness). The
         provisions of this Section 3H(ii) shall apply until the earlier to
         occur of (a) the seventh (7th) anniversary of the Closing Date or (b)
         the achievement of the 70% Condition. Notwithstanding the foregoing, if
         any OP Unit Recipient (i) obtains a tax-free step-up in the basis of
         their OP Units for federal income tax purposes; (ii) sells, transfers
         or otherwise disposes of their OP Units in a taxable transaction; or
         (iii) receives an allocation under Treasury Reg. Section 1.704-3(b)
         using the traditional method without curative allocations that reduces
         the amount of Built-in-Gain (as defined below), then the Debt Amount
         shall be commensurately reduced. For purposes of this Agreement,
         "Built-in-Gain" shall mean, with respect to each Property or Additional
         Property, the amount of taxable income in excess of "book" income that
         would be allocated to Contributor if such Property or Additional
         Property, as the case may be, were disposed of in a fully taxable
         transaction. After the seventh (7th) anniversary of the Closing Date
         and until the achievement of the 70% Condition, Acquiror will use
         commercially reasonable efforts to permit Contributor to guarantee
         available indebtedness of Acquiror or indemnify the REIT, Acquiror or
         any of their subsidiaries for liabilities in respect thereof, up to an
         amount equal to what the reduced Debt Amount would have been under this
         Section 3H(ii) if it were still applicable.

                      (iii) Allocation Method. Pursuant to Section 5.4 of the
         Partnership Agreement, Acquiror shall elect to use the "traditional
         method" without curative allocations set forth in Regulation Section
         1.704-3(b) with respect to the Properties.

                  I. Board Seat. The REIT shall take all actions necessary to
appoint Michael J. Falcone to the Board of Directors of the REIT at Closing,
with an initial term to last until the next annual meeting of the REIT's
stockholders. At such annual meeting, Michael J. Falcone shall be nominated to
serve as a Class I director of the REIT (i.e., with an initial term of three (3)
years).

                  J. Allocation of Contribution Consideration. Prior to the
Closing, the Second 


                                       15

<PAGE>


Closing and the Option Closing, as the case may be, and if requested by
Acquiror, Acquiror and Contributor shall use commercially reasonable efforts to
agree in writing upon the allocation of the Contribution Consideration and the
Additional Consideration, as the case may be, among the Land and the
Improvements. Acquiror and Contributor agree that the Personal Property has no
separate value except in connection with the Properties and Additional
Properties. No part of the Contribution Consideration is attributable to the
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, Additional Properties, the Partnership Interests and the
Management Contracts or to effect the other purposes of this Agreement.

                  L. Assumption of Debt; Deletion of Property. Contributor shall
use all commercially reasonable efforts to renegotiate the prepayment penalties
payable in respect of that portion of the Existing Indebtedness encumbering, or
related to, those Properties known as One Park Place, Syracuse, New York, and
1045 James Street, Syracuse, New York, and the Additional Property known as One
City Centre. If Contributor is unable to renegotiate such prepayment penalties
to Contributor's reasonable satisfaction, Contributor shall have the following
options:

                        (i) If Contributor is unable to renegotiate the
         prepayment penalties payable (and to renegotiate with the lender to
         allow for prepayment) in respect of that portion of the Existing
         Indebtedness encumbering, or related to, One Park Place, Syracuse, New
         York (the "Park Place Indebtedness"), Contributor shall have the
         option, exercisable upon written notice to Acquiror not less than five
         (5) business days prior to the Closing Date, to (i) delete and
         eliminate One Park Place, Syracuse, New York from this Agreement or
         (ii) contribute such Property to Acquiror subject to the Park Place
         Indebtedness and Acquiror shall assume the Park Place Indebtedness (the
         "Assumed Park Place Indebtedness"); provided, however, that on the
         Closing Date the Park Place Indebtedness shall not exceed the aggregate
         principal sum of $11,200,000 plus current interest. If Acquiror assumes
         the Park Place Indebtedness pursuant to this Section 3L(i), the
         Contribution Consideration shall be adjusted pursuant to the formula
         set forth in Schedule 3L.

                       (ii) If Contributor is unable to renegotiate the
         prepayment penalties payable in respect of that portion of the Existing
         Indebtedness encumbering, or related to, 1045 James Street, Syracuse,
         New York (the "James Street Indebtedness"), Contributor shall have the
         option, exercisable upon written notice to Acquiror not less than five
         (5) business days prior to the Closing Date, to (i) delete and
         eliminate 1045 James Street, Syracuse, New York from this Agreement or
         (ii) to contribute such Property to Acquiror subject to the James
         Street Indebtedness and Acquiror shall assume the James Street
         Indebtedness (the "Assumed James Street Indebtedness" and together with
         the Assumed Park Place Indebtedness, the "Assumed Indebtedness");
         provided, however, that on the Closing Date the James Street
         Indebtedness shall not exceed the aggregate principal sum of $3,427,259
         plus current interest. If Acquiror assumes the James Street
         Indebtedness pursuant to this Section 3L(ii), the Contribution
         Consideration shall be adjusted pursuant to the formula set forth in
         Schedule 3L.

                      (iii) If Contributor is unable to renegotiate the
         prepayment penalties payable in respect of that portion of the Existing
         Indebtedness encumbering, or related to, One City Centre, Contributor
         shall have the option, exercisable upon written notice to Acquiror on
         or prior to the date 


                                       16

<PAGE>

         which is five (5) business days prior to the Option Closing Date, to
         delete and eliminate One City Centre from this Agreement.

If Contributor exercises its option pursuant to this Section 3L to delete one or
more of the properties set forth in this Section 3L (each a "Contributor Deleted
Property," and together the "Contributor Deleted Properties"), this Agreement
shall, without further action of the parties, be deemed to have been
automatically and ipso facto amended to eliminate each Contributor Deleted
Property herefrom. Upon such amendment of this Agreement, (a) all references to
the Properties or Additional Properties, as the case may be, shall automatically
exclude the Contributor Deleted Properties and no obligations of Contributor (or
Acquiror's Conditions Precedent) set forth herein shall apply to the Contributor
Deleted Properties, (b) all references to Contributor and Owner shall
automatically exclude the Contributor(s) and Owner(s) appurtenant to the
Contributor Deleted Properties, (c) the Contribution Consideration or Additional
Consideration shall be reduced by the amount allocated to the Contributor
Deleted Properties and their related Management Contracts pursuant to Schedule
3B(i) and Schedule 3B(ii), and (d) Acquiror shall promptly return to Contributor
all documents, records and studies relating to the Contributor Deleted
Properties. Notwithstanding the foregoing, no such amendment shall modify any
indemnity or other obligation of a party regarding the Contributor Deleted
Properties which expressly survives the deletion of the Property or Additional
Property, or the termination of this Agreement.

                  In addition, if Frontier Corporation (a tenant at Three City
Centre) timely exercises its right of first refusal to purchase Three City
Centre, then Three City Centre shall be deemed a Contributor Deleted Property
for all purposes under this Agreement.

                  M. Reimbursement for Capital Expenditures. At the Closing, the
Second Closing and the Option Closing, Acquiror shall reimburse or pay
Contributor for those capital expenditures made or incurred by Contributor with
respect to the Properties (in the case of the Closing), Waterfront II (in the
case of the Second Closing) or One City Centre and Three City Centre (in the
case of the Option Closing) during the twenty four (24) month period preceding
the Closing Date, the Second Closing Date or the Option Closing Date, as the
case may be, (which capital expenditures shall be identified in writing by
Contributor at least three (3) business days prior to the Closing Date, the
Second Closing Date or the Option Closing Date, as the case may be); provided,
however, that the amount reimbursed under this Section 3M shall not exceed the
amount of cash payable to Contributor pursuant to Section 3B(i), Section 3B(ii),
Section 3B(iii) or Section 3B(iv), respectively (including the Additional Cash
Amount), in each case prior to any adjustment for this Section 3M. Acquiror
shall disburse the amounts payable pursuant to this Section 3M at the Closing,
the Second Closing and the Option Closing, as the case may be, to those people
specified by Contributor in writing at least three (3) business days prior to
the Closing Date, the Second Closing Date or the Option Closing Date,
respectively.

                  N. Notification if Representations and Warranties Untrue.
Prior to the Closing Date (with respect to the Properties), the Second Closing
Date (with respect to Waterfront II) or the Option Closing Date (with respect to
One City Centre and Three City Centre), 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. Contributor shall have thirty (30) days from
the date it receives such notification from Acquiror to cure such inaccuracy. If
the expiration of such thirty (30) day period occurs after the applicable
closing date and if Contributor is unable to cure such inaccuracy prior to the
closing date with respect to any property, then the applicable closing shall
occur for all unaffected properties and an additional closing shall occur for
the affected properties as soon as practicable thereafter, but in no event later
than the end of such thirty (30) day period. If an additional closing occurs,
the properties acquired at such additional closing shall be treated as if they
were acquired at the applicable closing for purposes of determining applicable
post-closing time periods under this Agreement.

                  O. Excepted Holder Limit. If at the time any OP Unit Recipient
exercises its Conversion Right the REIT elects to deliver Conversion Shares, and
the delivery of such Conversion Shares would violate the Ownership Limit (as
defined in the REIT's charter), then the REIT hereby covenants and agrees that
it will (i) create an Excepted Holder Limit (as defined in the REIT's charter)
for such OP Unit Recipient; or (ii) pay cash in lieu of Conversion Shares for
such OP Units (the cash amount to be determined as provided in the Partnership
Agreement).

                  P. Certain Partner Consents. With respect to the properties
known as 50-60 Lakefront Boulevard (Waterfront I), One City Centre, Three City
Centre and One Park Place, Contributor shall use its best efforts to obtain,
within 20 days of the date of this Agreement, all consents and approvals as may
be required to consummate the transactions contemplated by this Agreement from
each partner of the respective Contributed Entity. If, after using such best
efforts, Contributor is unable to obtain such consents and approvals within such
period of time with respect to any one or more of the properties known as 50-60
Lakefront Boulevard (Waterfront I) or One Park Place, then Contributor shall
promptly notify Acquiror, and Acquiror shall have the option either to terminate
this Agreement upon delivery to Contributor of a Termination Notice (in which
case, Section 14 shall not apply) or to consummate the transactions contemplated
by this Agreement; provided, however, that Contributor may delete One Park Place
and Acquiror may not then deliver a Termination Notice due to the failure to
obtain such consents and approvals with respect to One Park Place, and One Park
Place will thereafter be treated as a Contributor Deleted Property under this
Agreement. If, after using such best efforts, Contributor is unable to obtain
such consents and approvals within such period of time with respect to any one
or more of the properties known as One City Centre or Three City Centre, then
Contributor shall promptly notify Acquiror. If Acquiror elects to consummate the
transactions with respect to the Properties or does not elect to terminate its
option with respect to One City Centre and Three City Centre, then Contributor
will continue to use its best efforts to obtain such consents and approvals
until the Closing Date or the end of the Additional Property Option Period with
respect to One City Centre and Three City Centre, respectively. If, at such
time, Contributor is still unable to obtain such consents and approvals, then
this Agreement shall, without further action of the parties, be deemed to have
been automatically and ipso facto amended to eliminate each such property
herefrom (together, the "Eliminated Properties"). Upon such amendment of this
Agreement, (a) all references to the Properties or Additional Properties shall
automatically exclude the Eliminated Properties and no obligations of
Contributor (or Acquiror's Conditions Precedent) set forth herein shall apply to
the Eliminated Properties, (b) all references to Contributor and Owner shall
automatically exclude the Contributor(s) and Owner(s) appurtenant to the
Eliminated Properties, (c) the Contribution Consideration or Additional
Consideration shall be reduced by the amount allocated to the Eliminated
Properties and their related Management Contracts pursuant to Schedule 3B(i) and
Schedule 3B(ii), and (d) Acquiror shall promptly return to Contributor all
documents, records and studies relating to the Eliminated Properties.
Notwithstanding the foregoing, no such amendment shall modify any indemnity or
other obligation of a party regarding the Eliminated Properties which expressly
survives the deletion of the Property or Additional Property, or the termination
of this Agreement.

                  Q. Falcone Net Worth. Michael J. Falcone and Michael P.
Falcone hereby agree that, (i) at all times from and after the Closing Date and
up to and including the date which is the 18 month anniversary of the Closing
Date (or such later date as a claim for indemnification made by Acquiror is
resolved, provided that Acquiror made such claim in a timely manner as provided
in Sections 8E and 15), they will maintain a combined personal net worth of at
least $50,000,000; and (ii) at all times from and after the date which is the 18
month anniversary of the Closing Date and up to and including the date which is
the 18 month anniversary of the later of the Second Closing Date or the Option
Closing Date (or such later date as a claim for indemnification made by Acquiror
is resolved, provided that Acquiror made such claim in a timely manner as
provided in Sections 8E and 15), they will maintain a combined personal net
worth of at least $9,000,000 plus the amount of all timely claims for
indemnification made by Acquiror; provided, however, that in no event will they
be required to maintain a combined personal net worth exceeding $50,000,000.

                  R. Employees. Attached hereto as Exhibit N is a list of
employees who Acquiror will hire at Closing, the Second Closing or the Option
Closing, as applicable.

                  S. Industrial Development Authorities. To the extent required
by the terms of an IDA Lease Agreement, Acquiror and Contributor shall each use
their commercially reasonable efforts to obtain the consent of each applicable
IDA (the "IDA Consents") to the, direct or indirect, transfer of the leasehold
estate to Acquiror. Acquiror and Contributor shall each bear its own costs of
obtaining the IDA Consents. If Acquiror and Contributor are unable to obtain the
IDA Consent for any Property or Additional Property which is subject to an IDA
Lease Agreement by the Closing Date, the Second Closing Date or the Option
Closing Date, as the case may be, then Contributor shall take all necessary
steps to terminate the applicable IDA Lease Agreement and related IDA documents
and obtain the reconveyance of the applicable Property or Additional Property to
Contributor and Contributor shall transfer such Property or Additional Property
to Acquiror at the Closing, the Second Closing or the Option Closing, as the
case may be, pursuant to the terms and conditions of this Agreement applicable
to those properties to be transferred to Acquiror by deed transfer or
partnership assignment, without any reduction of the Contribution Consideration
or the Additional Consideration.

                  T. Additional Property Option. Acquiror shall have the option,
exercisable upon written notice to Contributor (the "Additional Property
Notice") during the period (the "Additional Property Option Period") beginning
on the date of this Agreement and ending on the date which is ninety (90) days
from the date of this Agreement, to purchase both One City Centre and Three City
Centre at the Option Closing as follows:

                        (i) If Acquiror delivers the Additional Property Notice,
         subject to the terms and conditions contained in this Agreement
         (including Contributor's right under Section 3L(iii) to delete One City
         Centre from this Agreement), ownership in and to One City Centre and
         Three City Centre shall be, directly or indirectly, transferred by
         Contributor to Acquiror at the Option Closing.

                       (ii) If Acquiror delivers the Additional Property Notice
         and Contributor has exercised its option to delete One City Centre from
         this Agreement pursuant to Section 3L(iii), subject to the terms and
         conditions contained in this Agreement, ownership in and to Three City
         Centre shall be, directly or indirectly, transferred by Contributor to
         Acquiror at the Option Closing.

                  U. Graphic Controls Corporation Lease. If Graphic Controls
Corporation is entitled to an initial abatement of fixed rent on the date
Acquiror acquires Waterfront II, Contributor will pay to Acquiror (on the first
of each month until Graphic Controls Corporation's initial obligation to pay
rent commences), an amount equal to (i) the monthly fixed rent Graphic Controls
Corporation would have paid on such first of the month but for the abatement
(each, a "Monthly Rent Payment"), minus (ii) the present value (calculated on
the date each Monthly Rent Payment is made) of an amount equal to the Monthly
Rent Payment twenty years into the future discounted at the rate of 10% per
annum.

                  V. Management Contracts. Acquiror hereby covenants and agrees
that neither it nor its Permitted Designees (as defined below) will sell or
otherwise dispose of the Management Contracts; provided, however, that Acquiror
or its Permitted Designees may cancel or otherwise terminate the Management
Contracts. Acquiror hereby covenants and agrees that, if the Management
Contracts are cancelled or otherwise terminated, neither it nor its Permitted
Designees will take the position that such cancellation or termination results
in an allocation of income to the Management Contributor.

                  W. One Park Place Lobby Renovations. Contributor and Acquiror
agree that certain renovation work (the "Renovation") to the building lobby of
One Park Place is necessary. Contributor has delivered to Acquiror the budget
for the Renovation and plans therefore (totaling $475,000). Contributor agrees
to perform (or cause to be performed) the Renovation promptly, in a good and
workmanlike manner, consistent with the budget and plans for the Renovation,
whether completed prior to or subsequent to the Closing. Acquiror agrees to pay
Contributor for the Renovation in accordance with the budget. Prior to Closing,
costs incurred in performing the Renovation shall be paid by Contributor but
shall be reimbursed by Acquiror at Closing in cash and in addition to all other
amounts which may be owed to Contributor at Closing. Subsequent to Closing,
costs incurred in performing the Renovation shall be paid by Contributor and
reimbursed by Acquiror within ten (10) business days of submission by
Contributor (not more frequently than monthly) to Acquiror of a reimbursement
request. Any request made by Contributor for reimbursement of costs incurred in
performing the Renovation, whether at Closing or pursuant to a reimbursement
request thereafter, shall be accompanied by invoices, receipts or other evidence
reasonably substantiating that such costs were incurred by Contributor or are
then due and owing in connection with the Renovation. If the Renovation is not
completed by the Closing, Acquiror shall allow Contributor access to One Park
Place as shall be necessary for Contributor to complete the Renovation. If Marsh
& McLennan, Inc. ("M&M") is entitled to receive free parking at One Park Place
pursuant to the terms of that certain letter agreement from Pioneer Development
Company, LLC to M&M regarding the Renovation, then Contributor shall pay to
Acquiror, on or prior to the date such amount would otherwise have been due and
payable by M&M, the amount which would have been paid by M&M but for M&M's right
to receive such free parking; provided, however, that Contributor shall not be
obligated to pay such amounts to the extent, but only the extent, the Renovation
would have been completed but for the fault of Acquiror. The provisions of this
Section 3W shall be deemed null and void if One Park Place is, or the
partnership interests of the owners thereof are, not conveyed to Acquiror at
Closing in accordance with the terms of this Agreement.

         4.       OPERATION OF PROPERTIES AND CONDUCT THROUGH CLOSING

                  A. Through the Closing Date (with respect to the Properties)
and through the Option Closing Date (with respect to One City Centre and Three
City Centre), each Owner shall:

                        (i) Except as otherwise provided for in this Agreement,
         manage and operate the Properties and One City Centre and Three City
         Centre, as the case may be, only in and shall not take any actions
         except in accordance with each Owner'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.

                       (ii) Not enter into any new lease, service contract or
         management contract or extend, modify, amend or renew any Lease,
         Service Contract or Management Contract without the prior written
         consent of Acquiror, which consent shall not be unreasonably withheld,
         conditioned or delayed; provided, however, each Owner may enter into
         new leases which pertain to less than 5,000 rentable square feet, or
         new service contracts with a duration of less than one year, or
         extensions, modifications, amendments or renewals of Leases which
         pertain to less than 5,000 rentable square feet or Service Contracts
         with a duration of less than one year, upon prior notice to, but
         without the consent of, Acquiror so long as such new lease or service
         contract or extension, modification, amendment or renewal of a Lease or
         Service Contract is on market terms with bona fide third

                                       22

         parties and is the type of transaction which each Owner currently
         enters into in the normal course of its business.

                      (iii) Not cancel any Lease, Service Contract or Management
         Contract without the prior written consent of Acquiror, which consent
         shall not be unreasonably withheld, conditioned or delayed.

                       (iv) Pursuant to the provisions of Section 9, provide
         Acquiror with access to the Properties for it to inspect same to assure
         that each Owner is complying with the requirements of this Section 4.

                        (v) Have the right to commence or continue to assert,
         whether before or after Closing, any proceedings or applications for
         reduction in the real estate tax assessment of any of the Properties or
         Additional Properties set forth in Schedule 4A(v) (a "Tax Reduction
         Proceeding") for any real estate tax year during which Acquiror or its
         Permitted Designee was not the fee or leasehold title holder of any of
         such Properties or Additional Properties, as the case may be. Have the
         right to commence, whether before or after Closing, a Tax Reduction
         Proceeding for any of the Properties or the Additional Properties for a
         real estate tax year in which both Owner and Acquiror or its Permitted
         Designee each held fee or leasehold title to any such Property, but
         only if (i) Acquiror notifies Contributor that Acquiror will not
         commence a Tax Reduction Proceeding for such real estate tax year or
         (ii) there remains thirty (30) days or less in which to institute a Tax
         Reduction Proceeding for such real estate tax year and Acquiror has not
         commenced a Tax Reduction Proceeding for such real estate tax year. To
         the extent Contributor commences any Tax Reduction Proceeding pursuant
         to this Section 4A(v), Contributor will notify Acquiror in writing of
         such commencement and provide copies of all documentation in connection
         therewith to Acquiror, and Contributor will use counsel it customarily
         uses (at their customary fee arrangement) with regard to Tax Reduction
         Proceedings. To the extent any Tax Reduction Proceeding is required to
         be brought in the name of Acquiror and Contributor has the right to
         commence such a proceeding hereunder, then Contributor shall have the
         right to commence such proceeding in the name of Acquiror. Acquiror
         agrees to cooperate with Contributor at no expense to Acquiror,
         including without limitation, executing any required documents, in
         connection with Contributor's commencement of a Tax Reduction
         Proceeding. To the extent any award or refund is paid to Contributor or
         Acquiror for any real estate tax year during which both parties owned
         fee or leasehold title to a Property, such party receiving such award
         or refund shall promptly deliver to the other party such party's
         allocable share of the award or refund after subtracting any required
         reimbursement to tenants and the out-of-pocket costs of obtaining such
         award or refund therefrom, including without limitation, the fees owed
         to certiorari counsel (which fees shall be paid by the party receiving
         the award or refund). To the extent any award or refund is paid to
         Acquiror for any real estate tax year during which only Contributor
         owned fee or leasehold title to a Property, Acquiror shall promptly
         deliver to Contributor the award or refund after subtracting any
         required reimbursement to tenants and the out-of-pocket costs of
         obtaining such award or refund therefrom, if any.

                       (vi) 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 and for One City Centre and
         Three City Centre that come into the possession or control of
         Contributor for any period(s) including the period between the date of
         this Agreement and the Option Closing Date.

                      (vii) Not sell, 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, conditioned or
         delayed, except that the loan with respect to Three City Centre may be
         modified pursuant to the terms Contributor previously disclosed to
         Acquiror.

                     (viii) Not sell, assign, grant any security interest in,
         pledge, encumber, dispose of, or otherwise transfer all or any part of
         any of the Partnership Interests with respect to the Properties except
         to another Contributor or its affiliate.

If Acquiror does not timely deliver the Additional Property Notice, the above
shall not apply to One City Centre and Three City Centre from and after
expiration of the Additional Property Option Period.

                  B.       Through the Second Closing Date the Owner of 
Waterfront II shall:

                        (i) Complete the expansion of Waterfront II in
         accordance with the construction plans relating thereto and keep the
         Land, the Improvements and the tangible Personal Property at Waterfront
         II in their current condition and repair, ordinary wear and tear
         excepted, other than in connection with such expansion.

                       (ii) Not enter into any new lease, service contract or
         management contract or extend, modify, amend or cancel the Lease with
         Graphic Controls Corporation or the IDA Lease Agreements relating to
         Waterfront II (except that the IDA Lease Agreement may be amended
         pursuant to the terms Contributor previously disclosed to Acquiror or
         is consistent with the Graphic Controls Corporation lease and the new
         financing described in Section 4B(vi)), or extend, modify, amend or
         renew any Service Contract or Management Contract relating to
         Waterfront II, without the prior written consent of Acquiror.

                      (iii) Not cancel any Lease, Service Contract or Management
         Contract pertaining to Waterfront II without the prior written consent
         of Acquiror.

                       (iv) Pursuant to the provisions of Section 9, provide
         Acquiror with access to Waterfront II for it to inspect same.

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

                       (vi) Not sell, grant any security interest in, pledge,
         encumber, dispose of, finance or refinance any indebtedness in respect
         of Waterfront II without the prior written consent of Acquiror, which
         consent shall not be unreasonably withheld, conditioned or delayed,
         except that the current financing may be replaced with the new
         financing which Contributor previously disclosed to Acquiror.

                      (vii) Not sell, assign, grant any security interest in,
         pledge, encumber, dispose of, or otherwise transfer all or any part of
         any of the Partnership Interests with respect to Waterfront II, except
         to another Contributor or its affiliate.

         5.       STATUS OF TITLE TO PROPERTIES

                  A. State of Title. The Deed Contributors shall convey the Deed
Properties to Acquiror or Acquiror's Permitted Designee by bargain and sale
deeds with covenants against grantor's acts in recordable form (the "Deeds"),
the Interest Contributors shall contribute their Partnership Interests to
Acquiror or Acquiror's Permitted Designee by the Partnership Interest
Assignments (as defined below) and the Management Contributor shall contribute
its interest in the Management Contracts to Acquiror or Acquiror's Permitted
Designee by an Assignment of Management Contracts (as defined below); provided,
however, that in the case of the Properties and Additional Properties that are
subject to lease agreements ("IDA Lease Agreements") with an Industrial
Development Authority ("IDA"), the Deed Contributor which holds the leasehold
interest in such Property or Additional Properties shall (subject to Section 3S
above) convey to Acquiror (in lieu of the foregoing) all leasehold right, title
and interest of such Deed Contributor in and to such Properties or Additional
Properties. Title to the Properties and Additional Properties shall be good,
marketable and insurable fee simple title, free and clear of all liens and
encumbrances and shall be subject only to: (i) those covenants, conditions,
liens, encumbrances, easements, assessments, restrictions, water and sewer
charges, related payment in lieu of taxes agreements ("PILOT Agreements") and
other title exceptions of record which are disclosed on each Title Commitment,
UCC Search and Survey (each as defined below) and are not objected to by
Acquiror within the Inspection Period (as defined below), (ii) rights of tenants
under the Leases, as tenants only (except with respect to tenants having a
purchase option or similar rights as disclosed in this Agreement), (iii) the
lien of the Existing Indebtedness, if any, on those Properties encumbered by the
Existing Indebtedness as of the date hereof and (iv) general real estate taxes
for the year in which the Closing, Second Closing or Option Closing, as the case
may be, occurs and subsequent years, not yet due and payable (the above
enumerated exceptions being hereinafter collectively referred to as the
"Permitted Exceptions"); provided, however, that in the case of the Properties
and Additional Properties that are subject to IDA Lease Agreements, the Deed
Contributor which holds the leasehold interest in such Property or Additional
Properties shall (subject to Section 3S above) convey to Acquiror all leasehold
right, title and interest of such Deed Contributor in and to such Properties and
Additional Properties, free and clear of all liens and encumbrances and subject
only to the Permitted Exceptions. The Partnership Interests shall be contributed
to Acquiror free and clear of all liens, claims and encumbrances.

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

                        (i) Acquiror shall obtain for each of the Properties and
         Additional 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 Permitted Designee and committing to
         insure title to the Properties and Additional 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. Acquiror shall direct the Title Insurer to
         deliver to Contributor and to Contributor's counsel copies of each
         Title Commitment at the same time the Title Insurer delivers each Title
         Commitment to Acquiror. The Title Commitment shall show fee simple
         title to the Properties and Additional Properties vested in Owner or
         the IDA, as the case may be. The Owner's Title Insurance Policy
         (collectively, the "Title Policies") to be issued to Acquiror at the
         Closing, the Second Closing or the Option Closing, as the case may be,
         pursuant to the 


                                       24

<PAGE>

         corresponding Title Commitment shall 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 or Additional Properties that do not connect to the
         Properties or Additional Properties, as the case may be, from a public
         street, and such other endorsements as counsel for Acquiror shall
         reasonably deem appropriate, all at Acquiror's sole cost and expense.

                       (ii) Acquiror, at its sole option and expense, may order
         and obtain 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 and Additional Properties are located for
         Uniform Commercial Code Financing Statements, tax liens and the like in
         the name of Contributor, the Properties, Additional Properties and any
         other name or location reasonably requested by Acquiror.

                      (iii) Acquiror may obtain, at its sole option and expense,
         a current "as-built" plat of survey (the "Survey") for each of the
         Properties and Additional 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 and Additional
         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, neither the
         Properties nor Additional Properties are 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 or Additional
         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 to any of the Properties (including Additional Properties), other than
Permitted Exceptions, or any other title or survey matter which does not conform
to the requirements of this Agreement with respect to any of the Properties or
Additional Properties, Acquiror shall so notify Contributor and Contributor may,
at its election, undertake to eliminate such unacceptable defects, objections or
exceptions, it being agreed that other than (i) final, unappealable judgments
against an Owner, (ii) mortgages or other liens which can be satisfied by
payment of a liquidated amount, other than the mortgages securing the Existing
Indebtedness, (iii) defects, objections or exceptions which can be removed by
payments not to exceed $25,000 for each Property including each Additional
Property and not to exceed $100,000 in the aggregate for all title defects, and
(iv) payments to the mortgagees which are currently required pursuant to
existing loan documents in order to cause the mortgagees to consent to Acquiror
assuming the Assumed Indebtedness, and except as provided below, Contributor
shall have no obligation to incur any expense or bring any action in connection
with curing such defects, objections or exceptions. Other than the items
described in (i) through (iv) above, which Contributor agrees to cure at its
sole cost and expense without regard to the cost thereof (other than as
expressly set forth in item (iii)), if after complying with the foregoing
requirements, Contributor is unable to or elects not to eliminate all
unacceptable defects, objections or exceptions in accordance with the terms of
this Agreement on or before the date which is at least two (2) business days
prior to the Closing Date, the Second Closing Date or the Option Closing Date,
as the case may be, Acquiror may elect either to (x) terminate this Agreement by
giving written notice to Contributor (a "Termination Notice") and, upon such
election, Acquiror shall immediately receive from Escrowee the Earnest Money, in
which event this Agreement, without further action of the parties hereto, 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 Section 9B (the "Surviving Indemnities"); (y) accept title subject
to such unacceptable defects, objections or exceptions and receive no credit
against or reduction of the consideration to be given to Contributor hereunder;
or (z) pursuant and subject to Section 10, delete and eliminate from this
Agreement any or all of the affected Properties or Additional Properties, at
Acquiror's sole election, and with respect to such Properties or Additional
Properties not so deleted, elect to accept title subject to such unacceptable
defects, objections or exceptions and receive no credit against or reduction of
the consideration to be given to Contributor hereunder. If Acquiror fails to
make any such election, and elects not to pursue its other rights and remedies
as aforesaid, Acquiror shall be deemed to have elected option (x) above.

         6.       CLOSING

                  A. Closing Date. The closing with respect to the Properties
contemplated by this Agreement (the "Closing") shall occur at the offices of
Rogers & Wells LLP, 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 fifteenth (15th) day after the
expiration of the Inspection Period or (ii) such other time and at such other
place as Contributor and Acquiror shall agree upon in writing. The "Closing
Date" shall be the date of the Closing.

                  B.       Closing Documents.
                           ------------------

                  Policy for each of the Properties (or marked-up commitment
                  therefor) in the form and condition required by this Agreement
                  (it being understood that Contributor will provide any
                  customary certificates or undertakings required in order to
                  induce the Title Insurer to insure over any "gap" period
                  resulting from any delay in recording of documents or
                  later-dating the title insurance file);

                  the Closing Date as being true, accurate and complete in all
                  material respects and all security deposits thereunder), an
                  assignment of those Service Contracts that Acquiror elects to

                  Section 3S above, an assignment and assumption of the
                  leasehold estates granted to a Deed Contributor under the IDA

                        (i) A statement of prorations and adjustments shall be
         prepared by Acquiror 

                                       34

         in conformity with the provisions of this Agreement and submitted to
         Contributor for review not less than three (3) business days prior to
         each of the Closing Date (with respect to the Properties), the Second
         Closing Date (with respect to Waterfront II) and the Option Closing
         Date (with respect to One City Centre and Three City Centre). For
         purposes of prorations, Acquiror shall be deemed the owner of the
         Properties on the Closing Date, the owner of Waterfront II on the
         Second Closing Date and the owner of One City Centre and Three City
         Centre on the Option 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)
         with respect to the Properties and Additional Properties, as of the
         Closing Date, the Second Closing Date or the Option Closing Date, as
         the case may be:

                           (a) The full amount of the cash security and other
                  cash deposits paid under the Leases, together with interest
                  thereon if required by law or under the Leases, shall be
                  credited to Acquiror, except to the extent any security
                  deposits have been applied, after the date of this Agreement,
                  to the curing of a default under the Lease and have not been
                  replenished. No such security deposits have been applied to
                  the curing of a default under the Lease and have not been
                  replenished as of the date of this Agreement;

                           (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, if 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, if final
                  invoices are not available, based on the most currently
                  available billing information, and reprorated upon issuance of
                  final invoices;

                           (d) For Properties which are not subject to IDA Lease
                  Agreements, all real estate, personal property and ad valorem
                  taxes applicable to the Properties or Additional Properties
                  and levied with respect to calendar year 1998 or the
                  appropriate fiscal year shall be prorated on an accrual basis,
                  as of the Closing Date, the Second Closing Date or the Option
                  Closing Date, as the case may be, utilizing the actual final
                  Tax Bills for the properties for 1997 (or 1998 if available)
                  adjusted for any announced changes in rates of taxation or
                  assessed valuation of the properties. Prior to or at the
                  Closing, Second Closing or Option Closing, as the case may be,
                  Contributor shall pay or have paid all Tax Bills that are due
                  and payable prior to or on the Closing Date, Second Closing
                  Date or Option Closing Date, as the case may be, and shall
                  furnish evidence of such payment to Acquiror and the Title
                  Insurer. For the Properties and Additional Properties, which
                  are subject to IDA Lease Agreements, taxes will be adjusted
                  pursuant to the applicable PILOT Agreement;

                           (e) All assessments, general or special, shall be
                  prorated as of the Closing Date, the Second Closing Date and
                  the Option Closing Date, as the case may be, 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, the Second Closing Date and the
                  Option Closing Date, respectively, and Acquiror shall be
                  responsible for any

                                       35

<PAGE>

                  installments of assessments which are first due or payable on
                  or after the Closing Date, the Second Closing Date and the
                  Option Closing Date, as the case may be;

                           (f) Except as set forth in Section 6(E)(i)(h),
                  commissions of leasing and rental agents for any Lease entered
                  into as of or prior to the Closing Date with respect to the
                  Properties, the Second Closing Date with respect to Waterfront
                  II or the Option Closing Date with respect to One City Centre
                  and Three City Centre, as the case may be, that are due and
                  payable at or prior to the Closing Date, the Second Closing
                  Date or the Option Closing Date, as the case may be, whether
                  with respect to base lease term, future expansions, renewals,
                  or otherwise, shall be paid in full at or prior to the
                  Closing, the Second Closing or the Option Closing, as the case
                  may be, 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 with respect to the Properties, the Second Closing
                  Date with respect to Waterfront II or the Option Closing Date
                  with respect to One City Centre and Three City Centre. At the
                  time(s) of final calculation and collection from tenants of
                  Additional Rent for 1998 (or for 1999 with respect to
                  Additional Properties, if applicable), 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, the Second Closing and the Option
                  Closing, as the case may be, and shall not merge into any
                  instrument of conveyance delivered at the Closing, the Second
                  Closing or the Option Closing, as the case may be. At the
                  Closing, the Second Closing and the Option Closing, as the
                  case may be, no "Delinquent Rents" (rents or other charges
                  which are due and owing as of the Closing, the Second Closing
                  or the Option Closing, as the case may be) shall be prorated
                  in favor of the Contributor. Notwithstanding the foregoing,
                  Acquiror shall use reasonable efforts after the Closing Date
                  with respect to the Properties, the Second Closing Date with
                  respect to Waterfront II and the Option Closing Date with
                  respect to One City Centre and Three City Centre, to collect
                  any Delinquent Rents due to the Contributor from tenants.
                  Further, after the Closing Date with respect to the
                  Properties, the Second Closing Date with respect to Waterfront
                  II or the Option Closing Date with respect to One City Centre
                  and Three City Centre, the Contributor shall continue to have
                  the right, enforceable at its sole expense, to pursue legal
                  action against any tenant (and any guarantors) who owe any
                  Base Rent or additional rent to Contributor for the period
                  prior to the Closing Date, the Second Closing Date or the
                  Option Closing Date, as the case may be, 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, the Second Closing or the Option Closing, as the case
                  may be, 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,
                  the Second Closing Date or the Option Closing Date, as the
                  case may be (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, the Second Closing Date or the Option

                  Closing Date, as the case may be, that the Contributor does
                  not pay or for which Acquiror does not receive a credit at the
                  Closing, the Second Closing or the Option Closing, as the case
                  may be, 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, the Second Closing or the Option
                  Closing Date, as the case may be (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 Leases set forth in Schedule 6E(i)(h)
                  attached to this Agreement are referred to herein as "New
                  Leases." 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"). For any new lease for any
                  such Vacancy ("Vacancy Lease") that is executed prior to
                  Closing, if the terms of such Vacancy Lease have been approved
                  by Acquiror (or were not approved, but approval is not
                  required pursuant to this Agreement), and for any New Leases,
                  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 and the New
                  Leases (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 or New Lease's term
                  that elapses after the rent commencement date and prior to
                  Closing and Acquiror's proportionate share shall be the
                  balance of the Vacancy Lease Costs. If this Agreement is
                  terminated prior to Closing, then Acquiror shall have no
                  liability or obligation with respect to any Vacancy Lease, any
                  New Lease or any Vacancy Lease Costs;

                           (i) Award or refunds in connection with a Tax
                  Reduction Proceeding pursuant to Section 4(A)(v); and

                           (j) 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 Additional
         Properties, as the case may be, and therefore entitled to the income
         therefrom and responsible for the expenses thereof, for the entire
         Closing Date, the Second Closing Date or the Option Closing Date, as
         the case may be, Second Closing Date and Option Closing Date, as the
         case may be. 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, the Second Closing or
         the Option Closing, as the case may be, shall be reprorated and finally
         adjusted within ninety (90) days after the Closing Date, the Second
         Closing Date or the Option Closing Date, as the case may be, otherwise
         all prorations shall be final.

                      (iii) Any errors in calculations or adjustments shall be
         corrected or adjusted as soon as practicable after the Closing, the
         Second Closing or the Option Closing, as the case may be; such
         adjustments shall be made in cash or OP Units at the election of
         Acquiror.

                       (iv) To the extent Acquiror receives a credit at the
         Closing, the Second Closing or the Option Closing, as the case may be,
         for any of the items set forth in this Section 6E, then such 

                                       37

<PAGE>

         item shall be the post-closing obligation of Acquiror.

                  F. Closing Costs. All transfer taxes, documentary stamps,
intangible taxes and similar taxes or charges 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, if any. Each party shall pay its own
attorney's fees and all of its other expenses, except as otherwise expressly set
forth herein.

                  G. Possession. Upon consummation of the Closing, the Second
Closing and the Option Closing, Contributor shall deliver to Acquiror full and
complete possession of the Properties and Additional Properties, as the case may
be, subject only to the Permitted Exceptions and other matters accepted by
Acquiror.

         7.  CASUALTY, LOSS AND CONDEMNATION

                  A. If, prior to the Closing, any single Property 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 Two Hundred Fifty Thousand
and 00/100 Dollars ($250,000.00) to a Property), Contributor shall immediately
so notify Acquiror and Acquiror shall be entitled to (i) pursuant and subject to
Section 10, delete and eliminate from this Agreement such Property affected by
such damage or destruction, at Acquiror's sole discretion, or (ii) subject to
the rights of holders of the Existing Indebtedness related to such Property,
receive the condemnation proceeds at Closing or settle the loss under all
policies of insurance applicable to the destruction or damage to such Property
if not deleted pursuant to Section 10, and receive the proceeds of insurance
applicable thereto at Closing, 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, prior to the Closing,
two or more 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 Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00) to a
Property), Contributor shall immediately so notify Acquiror and Acquiror shall
have the option either to terminate this Agreement upon delivery to Contributor
of a Termination Notice 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 (i) pursuant and subject to Section 10, delete and
eliminate from this Agreement any one Property affected by such damage or
destruction, at Acquiror's sole discretion, and (ii) with respect to the
Properties not so deleted, subject to the rights of holders of the Existing
Indebtedness related to such Property, receive the condemnation proceeds or
settle the loss under all policies of insurance applicable to the destruction or
damage to such Properties, 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 Two
Hundred Fifty Thousand and 00/100 Dollars ($250,000.00) or less) to a Property
or any part thereof, Acquiror shall have the right to (i) require Contributor to
repair such damage prior to the Closing, or (ii) require Contributor to assign
(subject to the rights of holders of the Existing Indebtedness related to such
Property) 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 


                                       38

<PAGE>

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.

                  B. If, prior to the Second Closing (with respect to Waterfront
II) or the Option Closing (with respect to One City Centre and Three City
Centre), any such property 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 Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00)),
Contributor shall immediately so notify Acquiror and Acquiror shall have the
option either to terminate this Agreement with respect to such Additional
Property upon delivery to Contributor of a Termination Notice or to consummate
the transaction contemplated by this Agreement with respect to such Additional
Property 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 to
the Additional Property, and receive the proceeds of insurance applicable
thereto, and Contributor shall, at the Second Closing, the Option 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 with respect to the Additional Property, this Agreement
shall, without further action of the parties, be deemed to have been
automatically and ipso facto amended to eliminate the Additional Property
herefrom. If there is any other damage or destruction (that is, damage or
destruction of Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00) or
less) to an Additional Property or any part thereof, Acquiror shall have the
right to (i) require Contributor to repair such damage prior to the Second
Closing or Option Closing, as the case may be, or (ii) subject to the rights of
holders of the Existing Indebtedness related to such Additional Property,
require Contributor to assign all insurance claims pertaining to such damage or
destruction to Acquiror by executing and delivering to Acquiror at the Second
Closing and Option Closing, as the case may be, 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 Second Closing or Option Closing, as the case may
be, a credit against the Additional Consideration in an amount equal to any
deductible(s) applicable thereto.

         8.  REPRESENTATIONS AND WARRANTIES

                  A. Michael J. Falcone and no other signatory hereto represents
and warrants to Acquiror that the following are true, complete and correct as of
the date of this Agreement:

                        (i) Each Owner is a general partnership duly organized
         and validly existing under the laws of the State of New York 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. Each Owner is duly qualified, licensed or admitted to do
         business 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 that individually or
         in the aggregate for all Owners would not materially adversely affect
         the Properties, Management Contracts, assets, business, operations or
         condition (financial or otherwise) of an Owner, individually or taken
         together with all Owners as a whole, or the ability of an Owner,
         individually or taken together with all Owners as a whole, to perform
         its obligations under this Agreement (an "Owner Material Adverse
         Effect"). Such jurisdictions are listed on Schedule 8A(i).


                                       39

<PAGE>

                       (ii) No Contributor or Owner has made a general
         assignment for the benefit of creditors, filed any voluntary petition
         in bankruptcy or suffered the filing of any involuntary petition by its
         creditors, suffered the appointment of a receiver to take possession of
         all, or substantially all, of its assets (except as disclosed on
         Schedule 8A(xxii)(1)), suffered the attachment or other judicial
         seizure of all, or substantially all, of its assets, admitted in
         writing its inability to pay its debts as they come due or made an
         offer of settlement, extension or composition to its creditors
         generally.

                      (iii) Each person or entity (other than Acquiror or the
         REIT) listed on the signature pages hereto (each, a "Signatory") has
         full requisite power and authority to enter into, execute and deliver
         this Agreement and to perform fully its obligations hereunder. The
         execution, delivery and performance by each Signatory of this Agreement
         and the execution, delivery and performance of the other documents to
         be delivered by each Signatory or other Contributor at Closing, the
         Second Closing, and the Option Closing, and the consummation by each
         Signatory and other Contributor of the transactions contemplated hereby
         and thereby have been (or will be with respect to documents to be
         delivered at the Closing, the Second Closing or the Option Closing)
         duly and validly authorized by all necessary action on the part of such
         Signatory or other Contributor and no other proceedings on the part of
         any Signatory, including of its partners, members or otherwise are
         necessary to authorize the execution, delivery and performance by such
         Signatory of this Agreement and the other documents to be delivered by
         such Signatory at the Closing, the Second Closing or the Option
         Closing, as the case may be, and the consummation by such Signatory of
         the transactions contemplated hereby and thereby, and no other
         proceedings on the part of any other Contributor, including of its
         partners, members or otherwise will be necessary (at the Closing, the
         Second Closing or the Option Closing, as the case may be) to authorize
         the execution, delivery and performance by such Contributor of the
         other documents to be delivered by such Contributor at the Closing, the
         Second Closing or the Option Closing, as the case may be, and the
         consummation by such Contributor of the transactions contemplated
         hereby and thereby. This Agreement has been duly executed and delivered
         by each Signatory and is a valid and binding obligation of each
         Signatory, enforceable against each Signatory in accordance with its
         terms.

                       (iv) Except as set forth in Schedule 8A(iv), neither the
         execution and delivery of this Agreement by any Signatory nor the
         performance by any Signatory or other Contributor or Contributed Entity
         of the transactions contemplated hereby will: (a) violate or conflict
         with any of the provisions of the partnership agreement or certificates
         of limited partnership, if any, (or similar organizational and
         governing documents) of any Contributor or Contributed Entity; (b)
         except as would not have an Owner 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, encumbrance, pledge, claim, security interest,
         demand, easement, covenant, condition, restriction and encroachment of
         any kind or nature (collectively, "Liens") in or upon any of the
         Properties or Additional Properties or assets of any Contributor or
         Contributed Entity 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 any Contributor or Contributed Entity is a
         party or by which it or any of its assets may be bound or affected; or
         (c) except as would not have an Owner 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 any Contributor,
         Contributed Entity, the Properties, Additional 




                                       40
<PAGE>


         Properties or the assets of any Contributor or Contributed Entity.
         Other than those which have been obtained or made prior to the date
         hereof, or as set forth in Schedule 8A(iv) 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, member, partner, shareholder, or tenant-in-common of any
         Contributor, Contributed Entity or other party is necessary or required
         for the execution, delivery and performance by each 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 an Owner Material Adverse Effect.

                        (v) To the best of each Owner's knowledge, it is not (a)
         in violation of its partnership agreement (or similar organizational
         and governing documents), (b) except as set forth in Schedules
         8A(xxii)(1) and 8A(vi) 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 it or its properties or 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 Owner Material Adverse Effect. To the best of each
         Owner'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 or Additional Properties, and (y) no Owner or any of the
         Properties or Additional 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 any Owner or its
         assets, the Properties or Additional Properties, occupancy of the
         Properties or Additional 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 an Owner
         Material Adverse Effect.

                       (vi) The Owners are the sole owners of fee simple title
         to the Properties that are not subject to IDA Lease Agreements. With
         respect to each of the Properties and Additional Properties subject to
         IDA Lease Agreements disclosed on Schedule B, such IDA is the sole
         lessor under the applicable IDA Lease Agreement for such Property or
         Additional Properties, as the case may be, and the respective Owner is
         the sole owner of the leasehold estate in and to such Property or
         Additional Property, as the case may be. Except as set forth in
         Schedule 8A(vi), each of the IDA Lease Agreements and the related PILOT
         Agreements are in full force and effect, and has not been modified,
         amended, or altered, in writing or otherwise and no Owner has received
         any notice of a default thereunder that remains outstanding. Each Owner
         has complied with (and, prior to the Closing, the Second Closing or the
         Option Closing, as the case may be, shall continue to comply with) in
         all material respects the terms of all IDA Lease Agreements, and all
         notices or correspondence received from the IDA. Except as set forth in
         Schedule 8A(vi), each Owner has paid (and, at all times prior to the
         Closing, the Second Closing or the Option Closing, as the case may be,
         shall pay), when and as due, all sums due under the IDA Lease
         Agreements. Each Owner has delivered to Acquiror true, complete and
         accurate copies of all IDA Lease Agreements. No Owner has 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 


                                       41

<PAGE>

         one or more of the Permitted Exceptions. To the best of each Owner's
         knowledge, there are no development or other rights associated with any
         Property or Additional Property which are not being transferred to
         Acquiror under this Agreement or the documents contemplated by this
         Agreement other than the Vacant Land.

                      (vii) Each Interest Contributor has or will have at the
         Closing, the Second Closing or the Option Closing, as the case may be,
         legal and beneficial title to one-hundred (100%) percent of their
         respective interest in the Contributed Entities to be contributed
         hereunder, free and clear of all Liens. The Partnership Interests
         represent all of the equity interests in the Contributed Entities. Each
         Interest Contributor has the power and authority to own its respective
         Partnership Interests, and the contribution of such Partnership
         Interests pursuant to this Agreement is or will be, to the extent
         necessary, authorized and within the power of each Interest Contributor
         on or prior to the Closing, the Second Closing or the Option Closing,
         as the case may be. At the Closing, the Second Closing or the Option
         Closing, as the case may be, Acquiror will receive legal and beneficial
         title to one-hundred (100%) percent of the Partnership Interests, free
         and clear of all Liens. Each partnership agreement of the Contributed
         Entities has been duly authorized, executed and delivered by each party
         thereto and constitutes a valid and binding obligation of those
         parties, enforceable in accordance with its terms. True and complete
         copies of such partnership agreements have been delivered to Acquiror,
         and have not been amended since their respective dates.

                     (viii) Each Owner has obtained and paid for (or caused to
         be 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
         Additional Properties, and all of the same are in good standing. To the
         best of each Owner's knowledge, the Properties and Additional
         Properties and each part thereof contain not less than the minimum
         number of parking spaces required under applicable law.

                       (ix) The schedule of insurance policies to be furnished
         to Acquiror pursuant to Section 11(iii) below will be true, complete
         and correct in all material respects, all such policies are in full
         force and effect and no Owner is in default with respect to any
         material provisions contained in any such policy. Neither any Owner
         nor, to the best of each Owner's knowledge, any agent of any Owner, has
         received from any insurer any notice with respect to any defects or
         inadequacies affecting all or any part of the Properties 
         or Additional 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.

                        (x) Except as set forth in Schedule 8A(x) attached to
         this Agreement, there is no judicial, municipal or administrative
         action, suit, arbitration, proceeding or investigation pending or, to
         the best of each Owner's knowledge, threatened against, relating to or
         affecting any Owner, its assets, the Properties, Additional 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

                                       42

         or Additional 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 each Owner's
         knowledge, threatened against any Owner.

                       (xi) Except as set forth in Schedule 8A(xi) attached to
         this Agreement, no Owner has received from any Governmental or
         Regulatory Authority any written notice of, nor is any Owner aware of,
         zoning, building, fire, health code, environmental or other violations
         of applicable laws, rules, ordinances codes and regulations with
         respect to the Properties, Additional Properties, or any part thereof.

                      (xii) The Service Contracts (which include the agreements
         set forth on Schedule 8A(xii)) and the Management Contracts comprise
         every contract, agreement, relationship and commitment, oral or
         written, other than the Leases, the IDA Lease Agreements, the Existing
         Indebtedness, the Waterfront II Indebtedness, the One City Centre
         Indebtedness and the Three City Centre Indebtedness, that affect the
         Properties or Additional Properties and to which any Owner 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 or Additional 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 any Owner nor, to the best of
         each Owner'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 Owner (or its assignees or successors)
         without payment of any penalty upon not more than thirty (30) days
         prior notice. Except as otherwise noted on Exhibit C or on Schedule
         8A(xii), no Service Contract is with an affiliate of Contributor.

                     (xiii) No Contributor or Contributed Entity has any
         patents, trademarks, servicemarks or trade names used in connection
         with the Properties or Additional Properties, except for the names
         "Pioneer Development Company, LLC" and "Pioneer Management Services
         Company, LLC." To the best of each such person'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 each such
         person's knowledge, threatened against any Contributor or any
         Contributed Entity with respect to alleged infringement of any patent,
         trademark, servicemark or trade name related to the Properties or
         Additional Properties.

                      (xiv) (a) Except as set forth on Schedule 8A(xiv), there
         is no proceeding, plan, study or effort by any governmental authority
         or agency pending, or to the best of each Owner's knowledge,
         threatened, which in any way affects or would affect the present use,
         improvements on, size or zoning of any of the Properties or Additional
         Properties (and no Owner has received any notice from any governmental
         authority of any such plan, study or effort), and there is no existing,
         or to the best of each Owner's knowledge, proposed or contemplated plan
         to widen, modify or realign any street or highway or any existing, or
         to the best of each Owner's knowledge, proposed or contemplated eminent
         domain proceedings that would affect any of the Properties or
         Additional Properties in any way whatsoever (and no Owner has received
         any notice from any governmental authority of any such existing,
         proposed or contemplated plan or proceedings); and

                           (b) To the best of each Owner's knowledge, all laws,
         ordinances, codes, rules 

                                       43
<PAGE>


         and regulations of any Governmental and Regulatory Authority, bearing
         on the construction, maintenance, repair or operation of each of the
         Properties and Additional Properties have been complied with by each
         Owner, except the non-compliance with which would not reasonably be
         expected to have an Owner Material Adverse Effect.

                       (xv) The Rent Roll is true, complete and correct in all
         material respects. 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. No Owner has
                  received any notice of any material claim of any sort that has
                  been asserted by anyone adverse to the rights of any Owner
                  under any of the Leases, or affecting or questioning the
                  rights of any Owner of the continued possession of the leased
                  or subleased premises under any such Lease;

                           (b) Except as set forth on the Rent Roll, all
                  obligations of the lessor under the Leases that accrue to the
                  date hereof 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 (with respect to the Properties), the
                  Second Closing (with respect to Waterfront II) or the Option
                  Closing (with respect to One City Centre and Three City
                  Centre) or subject to proration hereunder in all cases), and,
                  to the best of each Owner's knowledge, no tenant has
                  conditionally accepted lessor's performance of such
                  obligations. Except as set forth on the Rent Roll, no tenant
                  has asserted in writing 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
                  no Owner has any 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, on two or more occasions, 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 in writing that any Owner provide that tenant with
                  any reduction in the tenant's monetary obligations under its
                  Lease; (iii) no tenant has requested that any Owner, in its
                  capacity as landlord, permit the tenant to terminate its Lease
                  on an accelerated basis; (iv) no Owner has "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) no Owner
                  has 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, no Owner
                  has received any written notice from any tenant stating that,
                  or has knowledge that, a petition in bankruptcy has been 



                                       44

                  filed or is threatened to be filed by or against such tenant;

                           (f) Except with respect to security deposits and as
                  set forth on the Rent Roll, 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 each Owner'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 on the Rent Roll, there are
                  no brokers' commissions, finders' fees, or other charges
                  payable or to become payable to any third party on behalf of
                  any Owner in connection with any Lease, including, but not
                  limited to, any exercised option(s) to expand or renew;

                           (i) The Rent Roll sets forth all security deposits
                  paid by tenants under the Leases. (i) No tenant or any other
                  party has asserted any claim in writing (other than for
                  customary refund at the expiration of a Lease) to all or any
                  part of any security deposit and (ii) no Owner has applied any
                  portion of any security deposit to the payment of any sums due
                  from any tenant under a Lease, which sums have not been
                  reimbursed by such tenant;

                           (j) 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 Additional Properties, or any portion thereof,
                  or any right of first refusal to purchase any of the
                  Properties or Additional 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
                  Additional Properties or a portion thereof. Except as set
                  forth on the Rent Roll or due to a default by landlord or in
                  connection with a casualty or condemnation, 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 or
                  Additional Properties that such tenant is currently occupying;
                  and

                           (k) Except as set forth on the Rent Roll: (i) to the
                  best of each Owner's knowledge, no tenant has sublet its
                  leased premises; and (ii) there are no outstanding written
                  requests from any tenant to any Owner, 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.

                      (xvi) Except as set forth in Schedule 8A(xvi) attached to
         this Agreement, to the best of each Owner's knowledge, there are no
         general or special assessments applicable to the Properties or
         Additional Properties or any part thereof. The bill or bills issued for
         the years 1995, 1996, 1997 and 1998, 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 and
         Additional

         Properties (the "Tax Bills") (and to each Owner's knowledge, the only
         real estate tax bills applicable to the Properties or Additional
         Properties) have been delivered to Acquiror. Except as set forth in
         Schedule 8A(xvi) attached to this Agreement, no Owner has 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 or Additional
         Properties from that reflected in the most recent Tax Bills or PILOT
         Agreements. Except as set forth in Schedule 8A(xvi) attached to this
         Agreement, there is not now pending 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 each Owner's
         knowledge, will be, assessed against the Properties, or Additional
         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 Additional
         Properties, or any portion thereof, that are outstanding or unpaid,
         and, to each Owner's knowledge, none will be levied prior to the
         Closing, the Second Closing or the Option Closing, as the case may be.
         No Owner has 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, the
         Second Closing or the Option Closing, as the case may be, other than
         agreements entered into in connection with a Tax Reduction Proceeding
         permitted pursuant to Section 4(A)(v).

                     (xvii) Each Owner has prepared and timely filed all tax
         returns required to be filed on or before the date hereof with respect
         to its Properties and Additional Properties, which tax returns are
         true, correct and complete in all material respects. Except as set
         forth on Schedule 8A(xvii), each Owner has paid or made provision for
         the payment of all taxes with respect to its Properties and Additional
         Properties that are due or claimed to be due from it on or before the
         date hereof by any governmental taxing authority. Other than as set
         forth on Schedule 8A(xvii), no federal, state, local or foreign taxing
         authority has given written notice to any Owner of any tax deficiency,
         lien, interest or penalty or other assessment against the Properties or
         Additional Properties or any Owner which has not been paid and no audit
         or written inquiry has been commenced or, to the best of each Owner's
         knowledge, threatened by any federal, state, local or foreign tax
         authority relating to the Properties or Additional Properties or any
         Owner that may be expected to result in a tax deficiency, lien interest
         or other assessment against the Properties or Additional Properties.

                    (xviii) To the best of each Owner's knowledge, the Personal
         Property and the Excluded Personal Property is substantially all of the
         personal property owned by such Owner and used in the operation of its
         Properties and Additional Properties. Each Owner has good title to its
         Personal Property, free and clear of any Liens.

                      (xix) The financial information regarding the Properties
         and Additional Properties furnished by the Owners to Acquiror is true,
         complete and correct in all material respects and accurately set forth
         in all material respects the results of the operations of the
         Properties and Additional Properties for the periods covered.

                       (xx) The Management Contracts are the only management
         contracts pertaining to the Properties or Additional Properties and may
         be terminated by Acquiror following the advance notice specified in
         Schedule A, at no cost or expense to Acquiror.

                      (xxi) All utilities (including, without limitation, gas,
         electricity, telephone, water 


                                       46

         and sanitary and storm sewers) are connected to the Improvements as
         necessary, and all connection, hook-up, tap fees and the like have been
         paid.

                     (xxii) Except for the Existing Indebtedness, the Waterfront
         II Indebtedness, the One City Centre Indebtedness and the Three City
         Centre Indebtedness, there are no mortgages or deeds of trust presently
         encumbering the Properties or Additional Properties or any portion
         thereof. Except as set forth on Schedule 8A(xxii)(1), each Owner is in
         compliance with (and, prior to the Closing, the Second Closing or the
         Option Closing, as the case may be, 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 Indebtedness, the Waterfront II Indebtedness,
         the One City Centre Indebtedness and the Three City Centre Indebtedness
         (the "Existing Notes"). Except as set forth on Schedule 8A(xxii)(1),
         each Owner is current in the payment of (and, at all times prior to the
         Closing, the Second Closing or the Option Closing, as the case may be,
         shall pay, when and as due), all sums due under the Existing
         Indebtedness, the Waterfront II Indebtedness, the One City Centre
         Indebtedness or the Three City Centre Indebtedness, the Existing Notes
         and all other loan documents securing the Existing Notes (the "Other
         Loan Documents"). The Existing Notes, the Existing Indebtedness, the
         Waterfront II Indebtedness, the One City Centre Indebtedness and the
         Three City Centre Indebtedness and the Other Loan Documents are in full
         force and effect, and no Owner has received any notice of a default
         thereunder that remains outstanding except as may be related to a
         non-compliance set forth in Schedule 8A(xxii)(1) attached to this
         Agreement. Each Owner has delivered to Acquiror true, complete and
         accurate copies of the Existing Notes, the Existing Indebtedness, the
         Waterfront II Indebtedness, the One City Centre Indebtedness and the
         Three City Centre Indebtedness and the Other Loan Documents. Except as

         indebtedness evidenced by the Existing Notes may be prepaid, in full,
         on the Closing Date.

                    (xxiii) No representation or warranty made by any
         Contributor or Contributed Entity 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 (taking into account any
         knowledge, materiality or other similar qualifier contained therein).
         All items delivered by or on behalf of any Owner 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 any Owner
         to Acquiror pursuant to this Agreement constitute all of and the only
         Leases and other agreements to which any Owner is presently a party
         relating to or affecting the ownership, leasing, management and
         operation of the Properties and Additional Properties, there being no
         "side" or other agreements, written or oral, in force or effect, to
         which any Owner is a party or to which any Property or Additional
         Property is subject.

         attached to this Agreement; (y) any environmental report delivered to
         Acquiror by Contributor prior to the date of this Agreement; or (z) any
         environmental report procured by Acquiror regarding any of the
         Properties or the Additional Properties:

                           (a) The Properties and Additional Properties are
                  owned and operated by each Owner in compliance with all
                  Environmental Laws, except for instances of non-compliance as
                  would not individually or in the aggregate reasonably be
                  expected to have an Owner

                  Material Adverse Effect.

                           (b) No Owner has received in the past and there are
                  no pending or, to the knowledge of each Owner, threatened (in
                  writing) claims, complaints, notices, correspondence or
                  requests for information 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 Additional Properties or
                  any portion thereof.

                           (c) To the best of each Owner's knowledge, there have
                  been no Releases of a Hazardous Material at, on, under, in or
                  about any of the Properties or Additional Properties or any
                  portion thereof during any period that any Owner owned or
                  leased such Property or Additional Property or prior thereto.
                  None of the Properties or Additional Properties is listed, or
                  to the best of each Owner'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 each Owner's knowledge, no
                  conditions exist at, on, under, in or about the Properties or
                  Additional 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, except for those
                  which would not individually or in the aggregate have an Owner
                  Material Adverse Effect.

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

                           (f) No Owner has transported, disposed of or treated,
                  or arranged for the transportation, disposal or treatment of,
                  any Hazardous Material from the Properties or Additional
                  Properties or any portion thereof to any location that is: (i)
                  listed, or to the best of each Owner'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 each
                  Owner's knowledge, threatened, Federal, state or local
                  enforcement action or other investigation under any
                  Environmental Law.

                           (g) There are no underground storage tanks at, on or
                  under the Properties or Additional Properties or any portion
                  thereof. No Owner has removed, closed or abandoned any
                  underground storage tanks at any of the Properties or
                  Additional Properties, and no Owner has any knowledge of the
                  existence, abandonment, closure or removal of underground
                  storage tanks at any of the Properties or Additional
                  Properties.

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

         For purposes of this item (xxiv), the following terms shall have the

         limitation, the meaning of Release as defined under CERCLA.

                      (xxv) At the Closing Date, the Second Closing Date and the
         Option Closing Date, as the case may be, the only assets of the
         Contributed Entities will be the Partnership Properties listed on
         Schedule B and the related Personal Property, and the only liabilities
         of the 



                                     49

<PAGE>

         Contributed Entities will be the Assumed Indebtedness, if any, and
         liabilities incurred in the ordinary course of business with respect to
         the operation of the Partnership Properties prior to the Closing Date,
         the Second Closing Date or the Option Closing Date, as the case may be.

                     (xxvi) (a) Except as set forth in Schedule 8A(xxvi), at
         Closing (with respect to the Properties), the Second Closing (with
         respect to Waterfront II) and the Option Closing (with respect to One
         City Centre and Three City Centre), all gross income of the Contributed
         Entities and all gross income generated by the Deed Properties will be
         derived pursuant to the Leases and from no other sources, and (b) other
         than the Personal Property, the Service Contracts and the items
         specified in Section 1A(v) and (vi), all of the assets held by the
         Contributed Entities and all of the Deed Properties, at the Closing
         (with respect to the Properties), the Second Closing (with respect to
         Waterfront II) and the Option Closing (with respect to One City Centre
         and Three City Centre), will be assets described in Section
         856(c)(4)(A) of the Code.

                    (xxvii) Each Partnership Interest contributed by the
         Interest Contributors is an interest in a partnership that has been
         organized and at all times classified as a partnership for federal
         income tax purposes and for the applicable state income tax purposes
         and not as a corporation or an association taxable as a corporation.

                   (xxviii) Attached to this Agreement as Exhibit C and Schedule
         8A(xii) is a true and complete list of all the Service Contracts. There
         are no currently effective employment and union agreements affecting or
         pertaining in any way to the Properties, Additional Properties or any
         part thereof.

                  B. Michael J. Falcone represents and warrants to Acquiror
that, as of the Closing (with respect to the Properties), the Second Closing
(with respect to Waterfront II) and the Option Closing (with respect to One City
Centre and Three City Centre), each of the representations and warranties set
forth in Section 8A above shall be true, complete and correct in all material
respects except for changes in the operation of the Properties or Additional
Properties occurring prior to the Closing, the Second Closing or the Option
Closing, as the case may be, that are specifically permitted by or pursuant to
this Agreement.

                  C. Acquiror and the REIT represent and warrant 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 full partnership power and authority to
         enter into, execute and deliver this Agreement and to perform fully its
         obligations hereunder. The execution, delivery 


                                       50

         and performance by Acquiror of this Agreement and the other documents
         to be delivered by Acquiror at Closing, the Second Closing and the
         Option Closing, as the case may be, and the consummation by Acquiror of
         the transactions contemplated hereby and thereby are permitted under
         the Partnership Agreement, and at Closing, the Second Closing and the
         Option Closing, as the case may be, will have been duly and validly
         authorized by all necessary partnership action on the part of Acquiror,
         and no other partnership proceedings on the part of Acquiror, including
         of its partners, are necessary to authorize the execution, delivery and
         performance by Acquiror of this Agreement and the other documents to be
         delivered by Acquiror at Closing, the Second Closing and the Option
         Closing, as the case may be, and the consummation by Acquiror of the
         transactions contemplated hereby and thereby. 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) Neither the execution and delivery of this Agreement
         by Acquiror and the REIT nor the performance by Acquiror and the REIT
         of the transactions contemplated hereby will: (a) violate or conflict
         with any of the provisions of the Partnership Agreement or the REIT's
         Certificate of Incorporation or bylaws; or (b) except as would not have
         an Acquiror Material Adverse Effect or a REIT Material Adverse Effect
         (as defined below), violate or conflict with any Laws or Orders
         applicable to Acquiror, the REIT or their assets.

                       (iv) 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
         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.

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

                       (vi) 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,
         fully-paid and free of all Liens.

                      (vii) 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.

                     (viii) 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 

                                       51

<PAGE>

         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
         and its subsidiaries taken together as a whole (a "REIT Material
         Adverse Effect"). The REIT is the sole general partner of Acquiror.

                       (ix) The REIT has all requisite corporate power and
         authority to enter into, execute and deliver this Agreement,
         individually and in its capacity as general partner of Acquiror and to
         perform fully its obligations hereunder individually and 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, the Second Closing and the Option
         Closing, as the case may be, and the consummation by the REIT of the
         transactions contemplated hereby and thereby at Closing, the Second
         Closing and the Option Closing, as the case may be, 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.

                        (x) 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.

                       (xi) 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, free of all Liens and upon official notice of issuance
         will be listed on the AMEX (or such other exchange or national
         quotation system as the Common Stock is then traded on).

                      (xii) The REIT, beginning with its taxable year ended
         December 31, 1993 and through December 31, 1997 (i) has been subject to
         taxation as a "real estate investment trust" (a "REIT Entity") within
        d the meaning of the Code and has complied with all requirements
         contained in the Code to qualify as a REIT Entity for such years, and
         (ii) has operated, and currently intends to continue to operate, in
         such a manner as to qualify as a REIT Entity for the tax year ending
         December 31, 1998 and thereafter.

                     (xiii) 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 REIT Material Adverse Effect.

                      (xiv) The REIT has filed all forms, reports, schedules,
         proxy materials, 


                                       52

         registration statements and related prospectuses and supplements and
         other documents required to be filed by the REIT with the Securities
         and Exchange Commission (the "SEC") pursuant to the Securities Act or
         the Securities Exchange Act of 1934, as amended, for the year ended
         December 31, 1997 and from December 31, 1997 up to the date hereof
         (collectively, the "SEC Documents") and will cause to be delivered to
         Contributor copies of such additional documents as may be filed with
         the SEC by the REIT between the date hereof and the Closing Date. The
         SEC Documents were, and those additional documents filed between the
         date hereof and the Closing will be, prepared and filed in all material
         respects in compliance with the rules and regulations promulgated by
         the SEC, and do not contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein in order
         to make the statements contained therein, in light of the circumstances
         under which they were made, not misleading. Except as set forth on
         Schedule 8C(xiv), no material event has occurred between the date of
         the REIT's most recent report filed with the SEC and the date of this
         Agreement which would be required to be disclosed in a document filed
         with the SEC.

                       (xv) The consolidated financial statements included in
         the SEC Documents have been prepared in accordance with generally
         accepted accounting principles applied on a consistent basis during the
         period involved (except as may be indicated in the notes thereto or, in
         the case of the unaudited statements, as permitted by Form 10-QSB) and
         present fairly (subject, in the case of the unaudited statements, to
         normal, recurring year-end audit adjustments) the consolidated
         financial position of Acquiror or the REIT, as applicable, and their
         respective Subsidiaries (as defined below) at the dates thereof and the
         consolidated results of operations and cash flows for the periods then
         ended. "Subsidiaries" means (i) any entity of which Acquiror or the
         REIT (or other specified entity), as applicable, shall own directly or
         indirectly through a subsidiary, a nominee arrangement or otherwise (x)
         at least a majority of the outstanding capital stock (or other shares
         of beneficial interest) or (y) at least a majority of the partnership,
         joint venture or similar interests, and (ii) any entity in which
         Acquiror or the REIT (or other specified entity), as applicable, is a
         general partner or joint partner, including without limitation in the
         case of the REIT, Acquiror.

                      (xvi) As of April 27, 1998, (A) the authorized shares of
         stock of all classes of the REIT consists of 65,000,000 shares of
         capital stock, par value $.001 per share, and all of such shares are
         initially classified as "Common Stock"; (B) the issued and outstanding
         shares of the REIT consists of 5,487,386 shares of Stock; and (C) no
         shares of preferred stock of the REIT are outstanding.

                    (xvii) As of April 27, 1998, 9,459,743 OP Units are issued 
         and outstanding.

                    (xviii) Neither the REIT nor Acquiror has made a general
         assignment for the benefit of creditors, filed any voluntary petition
         in bankruptcy or suffered the filing of any involuntary petition by
         either of the REIT's or Acquiror's creditors, suffered the appointment
         of a receiver to take possession of all, or substantially all, of the
         REIT's or Acquiror's assets, suffered the attachment or other judicial
         seizure of all, or substantially all, of the REIT's or Acquiror's
         assets, admitted in writing its inability to pay its debts as they
         come due or made an offer of settlement, extension or composition to
         its creditors generally.

                      (xix) Attached hereto as Schedule 8C(xix) is a listing
         (the "REIT Rent Roll") of the following as of March 31, 1998, which is
         true, complete and correct in all material respects for all properties
         in which the REIT holds an interest (collectively, the "REIT
         Property"): (i) the name 


                                       53

<PAGE>


         of each tenant; (ii) the fixed rent required to be paid; (iii) the
         expiration date of each lease; and (iv) any arrearages of any tenant
         beyond thirty (30) days.

                       (xx) Acquiror was not and is not a publicly traded
         partnership within the meaning of Section 7704 of the Code and the
         regulations promulgated thereunder. In addition, no subsidiary of
         Acquiror or the REIT has taken the position, for federal income tax
         purposes, that it is a publicly traded partnership within the meaning
         of Section 7704 of the Code or the regulations promulgated thereunder.

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

                  E. Except as hereinafter provided, all representations and
warranties made in this Section 8 by Michael J. Falcone and by Acquiror and the
REIT (i) which pertain to the Properties or the ownership, operation or status
of the Properties or the Owners thereof, shall survive the Closing until the
eighteen (18) month anniversary of the Closing Date, (ii) which pertain to
Waterfront II or the ownership, operation or status of Waterfront II or the
Owner thereof, shall survive the Second Closing Date until the eighteen (18)
month anniversary of the Second Closing Date, and (iii) which pertain to One
City Centre or Three City Centre or the ownership, operation or status of One
City Centre or Three City Centre or the Owners thereof, shall survive the Option
Closing Date until the eighteen (18) month anniversary of the Option Closing
Date, and shall not merge into any instrument of conveyance delivered at the
Closing, the Second Closing or the Option Closing, as the case may be; 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 15 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 15. 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, the Second
Closing Date or the Option Closing Date, as the case may be, which shall survive
for the respective periods set forth herein. Notwithstanding the foregoing, the
representations and warranties contained in Section 8A (xxv) shall survive until
the seventh (7th) anniversary of (i) the Closing Date with respect to the
Contributed Entities relating to the Properties; (ii) the Second Closing Date
with respect to the Contributed Entity relating to Waterfront II; and the Option
Closing Date with respect to the Contributed Entities relating to One City
Centre and Three City Centre.

                  F. Contributor shall provide to Acquiror and its auditors (i)
during the Inspection Period and following the Closing, the Second Closing or
the Option Closing, as the case may be, access at all reasonable times to all
financial and other information relating to the Properties and Additional
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 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, the Second Closing or the Option
Closing, as the case may be, (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, the Second Closing or the Option Closing, as the case may
be, for a period of eighteen (18) months.

         9.       ACQUIROR'S INSPECTION OF THE PROPERTIES

                  A. Subject to the provisions of Section 9B, during the period
extending to and including the 60th day from the date of this Agreement (the
"Inspection Period"), Acquiror and Acquiror's employees, agents, engineers,
surveyors, consultants, appraisers, auditors and other representatives
(collectively, "Representatives") will, upon reasonable advance notice to and
approval from Contributor, be given the right to enter upon the Properties and
Additional 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 Additional 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 or Additional Properties), as Acquiror or Acquiror's Representatives
may reasonably request. Subject to Section 8F, 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, plans
and specifications, surveys, appraisals, engineering and architect reports, real
estate tax bills and receipts, operating statements and related documents.
Acquiror shall have the right, at its sole cost and expense, to perform a Phase
One environmental assessment of each of the Properties and Additional
Properties. Upon Acquiror's receipt of any such Phase One assessment, it shall
promptly 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 or Additional 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; any such further inspections or testings shall be conducted
at the sole cost and expense of Acquiror. 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 or Additional
Properties (the "Inspection Condition"). If the Inspection Condition is not so
satisfied, Acquiror, prior to the expiration of the Inspection Period, in its
sole discretion, may deliver to Contributor a Termination Notice; provided that
if the Inspection Condition is not satisfied with respect to the results of any
environmental, survey or engineering investigation and evaluation, then, at
Acquiror's sole election (pursuant to and subject to the terms of Section 10),
rather than delivering to Contributor a Termination Notice, Acquiror may delete
and eliminate from this Agreement any or all of the Properties, or Additional
Properties, for which the results of such environmental, survey or engineering
investigation and evaluation does not meet Acquiror's satisfaction. 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
9B. If Acquiror does not give the Termination Notice or the Property Deletion
Notice (as defined below) 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 or to delete and
eliminate properties, pursuant to and subject to the terms of this Section 9 and
Section 10, shall be deemed deleted from this Agreement and, subject to all
other conditions and provisions contained in this Agreement, the parties shall
proceed to Closing without any credit against or reduction of the Contribution
Consideration.


                                       56

<PAGE>


                  B. Acquiror acknowledges and agrees that all physical damage
resulting from any test, survey inspection and/or examination done by Acquiror
or its Representatives at any of the Properties or Additional Properties shall
be repaired by Acquiror at its sole cost and expense. Acquiror shall hold
Contributor harmless and indemnify Contributor for any Losses (as defined below)
resulting from Acquiror's inspection of the Properties or Additional Properties
described in Section 9A and which would not have been incurred but for the acts
or omissions of Acquiror or its Representatives, provided that if any claim
relating thereto is asserted against Contributor, Contributor shall promptly
give written notice thereof to Acquiror and allow Acquiror a reasonable
opportunity to defend same, and provided further that Acquiror shall have no
liability to Contributor for any Losses for which Contributor receives proceeds
from its existing insurance, and Contributor waives any right of recovery
against Acquiror for the amount of such insurance proceeds (it being agreed that
Contributor shall have no obligation to make a claim with its insurance carrier
as a condition to proceeding against Acquiror).

         10.      DELETION OF PROPERTIES

                  A. Deletion of Properties. If Acquiror does not exercise its
unilateral right to deliver a Termination Notice pursuant to Sections 5C, 7, or
9, Acquiror may nevertheless elect to proceed with the acquisition of less than
all of the Properties or the Additional Properties, and to delete and eliminate
from this Agreement those certain Properties (or Additional Properties) that
Acquiror, in its sole discretion (but subject to the limitations set forth in
this Agreement with respect to acceptable reasons for Acquiror to so delete a
Property or Additional Property), elects not to acquire (the "Deleted
Properties"), pursuant to the delivery to Contributor, not later than fifteen
(15) days prior to the Closing Date (unless otherwise provided for in this
Agreement), of written notice describing the Deleted Properties and the reasons
for such deletion (the "Property Deletion Notice"), under which Acquiror may
exercise the foregoing partial termination option and designate those specific
Properties (or Additional Properties), that shall constitute Deleted Properties
under this Agreement. Upon the delivery by Purchaser of a Property Deletion
Notice, this Agreement shall, without further action of the parties, be deemed
to have been automatically and ipso facto amended to eliminate the Deleted
Properties herefrom. Upon such amendment of this Agreement, (a) all references
to the Properties or Additional Properties, as the case may be, shall
automatically exclude the Deleted Properties and no obligations of Contributor
(or Acquiror's Conditions Precedent) set forth herein shall apply to the Deleted
Properties, (b) all references to Contributor and Owner shall automatically
exclude the Contributor(s) and Owner(s) appurtenant to the Deleted Properties
with respect to such Properties, (c) the Contribution Consideration or
Additional Consideration shall be reduced by the amount allocated to the Deleted
Properties and their related Management Contracts pursuant to Schedule 3B(i) and
Schedule 3B(ii), and (d) Acquiror shall promptly return to Contributor all
documents, records and studies relating to the Deleted Properties.
Notwithstanding the foregoing, no such amendment shall modify any indemnity or
other obligation of a party regarding the Deleted Properties which expressly
survives the deletion of the Property or Additional Property, or the termination
of this Agreement. In all events, however, Acquiror's rights under this Section
10A are expressly subject to the specific limitations imposed under Section 10B
below.

                  B. Maximum Deletion. In the aggregate with respect to Sections
5C and 9, Acquiror may deliver Property Deletion Notices pursuant to Section 10A
with respect to either (i) any single Property or Additional Property; or (ii)
one or more Deleted Properties which, in the aggregate, represent no more than
$15,000,000 of the total aggregate Contribution Consideration. In addition, in
connection with Section 7, Acquiror may deliver a Property Deletion Notice
pursuant to Section 10A with respect to any single Property or Additional
Property.

         coverage amounts thereunder;

                       (iv) copies of all audited, where available, or unaudited
         financial statements for 1995, 1996 and 1997, and all available
         financial statements for 1998; and

                        (v) copies of the most recent survey of and title policy

         12.      CONDITIONS PRECEDENT

                  A. Acquiror's obligation to acquire the Properties shall be
subject to and contingent upon the following conditions precedent with respect
to the Properties, any or all of which Acquiror may waive only by a notice
delivered in accordance with Section 16G:

                        (i) The willingness of the Title Insurer to issue to

         premiums.

                       (ii) Contributor shall have obtained and delivered to
         Acquiror original executed tenant estoppel certificates (the "Tenant
         Estoppel Certificates") in substantially the form of Exhibit O attached

         executed by tenants under Leases leasing not less than eighty-five
         percent (85%) of the total aggregate gross rental income for all of the
         Properties, including, without limitation, those particular tenants of
         the Properties listed in Exhibit P attached hereto ("Required Estoppel
         Tenants"). Contributor shall use its reasonable, good faith and
         diligent efforts to obtain the Tenant Estoppel Certificates from all
         tenants under the Leases. 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 delivery of a notice of termination, on or
         before the Closing Date, which notice is sufficient to terminate all of
         the Service Contracts that Acquiror has a right to and has elected to
         terminate by written notice given to Contributor prior to the
         expiration of the Inspection Period.

         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 by Contributor of all consents and

                     (viii) Contributor not being otherwise in default of any of
         its material obligations under this Agreement.

                       (ix) Contributor shall have delivered pay-off letters

                        (x) Michael J. Falcone and Michael P. Falcone shall have
         delivered to Acquiror a net worth statement, in form and substance
         reasonably satisfactory to Acquiror, stating a combined personal net
         worth of at least $50,000,000.

                  Notwithstanding anything contained in Section 14B herein to
the contrary, if the condition precedent set forth in Section 12A(i) is not
satisfied or waived on or prior to the Closing Date, Acquiror shall only have
the rights and remedies set forth in Section 5C. Notwithstanding anything
contained in Section 14B herein to the contrary, if the condition precedent set
forth in Sections 12A(ii) is not satisfied or waived on or prior to the Closing
Date, Acquiror shall only 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
12A(iii), (iv), (v), (vi), (vii), (viii), (ix) and (x) is not satisfied or
waived on or prior to the Closing Date, then Acquiror shall have the rights and
remedies provided in Section 14B.

                  B. Contributor's obligation to contribute and convey the
Properties shall be subject to and contingent upon the following conditions
precedent with respect to the Properties, any or all of which Contributor may
waive by a notice delivered in accordance with Section 16G:

                        (i) The representations and warranties made by Acquiror
         in this Agreement shall be true and correct in all material respects on

         by Acquiror, where required) required under Section 6B(ii).

                      (iii) Between the date of this Agreement and the Closing
         Date, Acquiror and the REIT shall not have entered into a line of
         business substantially different from its current business.

                       (iv) Acquiror not being otherwise in default of any of
         its material obligations under this Agreement.

                        (v) The delivery by Acquiror of all consents and
         approvals as may be required for Acquiror to consummate the
         transactions contemplated by this Agreement.

                  If any of the conditions precedent set forth in Section 12B is
not satisfied or waived on or prior to the Closing Date, then Contributor shall
have the rights and remedies provided in Section 14A.

                  C. Acquiror's obligation to acquire the Additional Properties
shall be subject to and contingent upon the following conditions precedent at
the Second Closing or the Option Closing, as the case may be, with respect to
the applicable Additional Property, any or all of which Acquiror may waive only

         be, the Title Policies in accordance with Section 5B(i), upon the sole
         condition of the payment of the applicable premiums.

                       (ii) With respect to Waterfront II, Contributor shall
         have obtained and delivered to Acquiror an original executed Tenant
         Estoppel Certificate, dated not more than thirty (30) days before the
         Second Closing, and executed by Graphic Controls Corporation, the sole
         tenant under the Lease related to Waterfront II. Such Tenant Estoppel
         Certificate shall appropriately identify the full and complete Lease
         but will omit certifications that are inappropriate. With respect to
         One City Centre and Three City Centre (if Acquiror has delivered the
         Additional Property Notice), Contributor shall have obtained and
         delivered to Acquiror original executed Tenant Estoppel Certificates in
         substantially the form of Exhibit O attached hereto, dated not more
         than thirty (30) days before the Option Closing, and executed by
         tenants under Leases leasing not less than eighty-five percent (85%) of
         the total aggregate gross rental income for all of each such property,
         including, without limitation, the Required Estoppel Tenants listed in
         Exhibit P attached hereto with respect to One City Centre and Three
         City Centre. Contributor shall use its reasonable, good faith and
         diligent efforts to obtain the Tenant Estoppel Certificates from all
         tenants under the Leases with respect to the Additional Properties.
         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 delivery of a notice of termination, on or
         before the Second Closing Date or the Option Closing, as the case may
         be, which notice is sufficient to terminate all of the Service
         Contracts with respect to Additional Properties that Acquiror has a
         right to and has elected to terminate by written notice given to
         Contributor.

                       (iv) The representations and warranties made by Michael
         J. Falcone in this Agreement (as they relate to the transactions to be
         consummated at the Second Closing or the Option Closing, as the case
         may be) shall be true and correct in all material respects on the
         Second Closing Date or the Option Closing, as the case may be, as if
         made on the Second Closing Date or the Option Closing, as the case may
         be.

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

         approvals as may be required to consummate the transactions
         contemplated by this Agreement with respect to the Second Closing or
         the Option Closing, as the case may be.

                      (vii) The delivery of all consents and approvals set forth
         on Schedule 8A(iv) to this Agreement other than the IDA Consents with
         respect to Additional Properties.

                     (viii) Contributor not being otherwise in default of any of
         its material obligations under this Agreement.

         with respect to the Waterfront II Indebtedness, the One City Centre
         Indebtedness and the Three City Centre Indebtedness.

                        (x) With respect to Waterfront II, Graphic Controls
         Corporation has taken possession of Waterfront II and Contributor has
         obtained a permanent certificate of occupancy for the space covered by,
         and the use contemplated by, the related Lease.

                       (xi) Michael J. Falcone and Michael P. Falcone shall have
         delivered to Acquiror a net worth statement, in form and substance
         reasonably satisfactory to Acquiror, stating a combined personal net
         worth of at least $9,000,000 plus the amount of all timely claims for
         indemnification made by Acquiror; provided, however, that in no event
         will such statement be required to state a combined personal net worth
         exceeding $50,000,000.

                  Notwithstanding anything contained in Sections 14D or 14F
herein to the contrary, if any of the conditions precedent set forth in Sections
12C(i) or (ii) is not satisfied or waived on or prior to the Second Closing Date
or the Option Closing, as the case may be, Acquiror shall only have the right to
terminate this Agreement with respect to the applicable Additional Properties
upon written notice to Contributor, and this Agreement, without further action
of the parties, shall become null and void with respect to such Additional
Properties and neither party shall have any further rights or obligations under
this Agreement with respect to Additional Properties except with respect to the
Surviving Indemnities. If any of the conditions precedent set forth in Section
12C (iii), (iv), (v), (vi), (vii), (viii), (ix), (x) and (xi) is not satisfied
or waived on or prior to the Second Closing Date or the Option Closing, as the
case may be, then Acquiror shall have the rights and remedies provided in
Section 14D.

                  D. Contributor's obligation to contribute and convey
Additional Properties shall be subject to and contingent upon the following
conditions precedent with respect to Additional Properties, any or all of which
Contributor may waive by a notice delivered in accordance with Section 16G:

                        (i) The representations and warranties made by Acquiror

         the Second Closing Date or the Option Closing Date, as the case may be,
         as if made on the Second Closing Date or the Option Closing Date, as
         the case may be.

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

                                       61

<PAGE>


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

                       (iv) The delivery by Acquiror of all consents and
         approvals as may be required for Acquiror to consummate the
         transactions contemplated by this Agreement with respect to the Second

                  If any of the conditions precedent set forth in Section 12D is
not satisfied or waived on or prior to the Second Closing Date or the Option
Closing, as the case may be, then Contributor shall have the rights and remedies
provided in Section 14C.

         13.      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.

         14.      DEFAULT AND REMEDIES

                  A. If, prior to the Closing, Acquiror is in default with
respect to, or breaches, or fails to perform one or more of the representations,
warranties, covenants or other terms of this Agreement, and such default, breach
or failure is not cured or remedied within five (5) business days prior to the
Closing Date, 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 Surviving
Indemnities. 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 five (5) business days prior to the
Closing Date, 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 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. If
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; provided, however, that in no event shall Contributor be required to

                                       62

<PAGE>

reimburse Acquiror for any such expenses in excess of (i) if prior to the end of
the Inspection Period, $500,000; and (ii) if after the Inspection Period,
$1,000,000.

                  C. If, after the Closing has occurred, but prior to the Second
Closing, Acquiror is in default with respect to, or breaches, or fails to
perform one or more of the representations, warranties, covenants or other terms
of this Agreement related to Waterfront II, and such default, breach or failure
is not cured or remedied within five (5) business days prior to the Second
Closing Date or otherwise waived by Contributor, Contributor may terminate this
Agreement with respect to Waterfront II and, as its sole remedy, receive
$100,000 from Acquiror, as liquidated damages, and, upon such payment, the
parties shall be released from all further obligations and liabilities under
this Agreement with respect to Waterfront II, except with respect to the
Surviving Indemnities. 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
payment stated above has been determined by the parties as a reasonable sum for
damages and is intended not as a penalty, but as full liquidated damages.

                  D. If, after the Closing has occurred, but prior to the Second
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 related to Waterfront II, and such default, breach or failure
is not cured or remedied within five (5) business days prior to the Second
Closing Date or otherwise waived by Acquiror, Acquiror as its sole remedy may
either (a) terminate this Agreement with respect to Waterfront II, in which
event Contributor shall pay Acquiror $100,000 and, upon such payment, the
parties shall be released from all further obligations and liabilities under
this Agreement with respect to Waterfront II, except with respect to the
Surviving Indemnities, or (b) sue for specific performance. If Acquiror elects
the remedy set forth in (a) above, Contributor shall make such payment within
fifteen (15) days after Contributor's receipt of written notice from Acquiror.
It is recognized by Contributor and Acquiror that the damages Acquiror will
sustain by reason of Contributor's default, breach or failure will be
substantial, but difficult, if not impossible, to ascertain. The payment stated
above has been determined by the parties as a reasonable sum for damages and is
intended not as a penalty, but as full liquidated damages. It is understood and
agreed that if, due to no fault of Contributor, Graphic Controls Corporation
terminates its Lease, then notwithstanding the provisions of this Section 14D,
Acquiror shall not be entitled to receive liquidated damages from Contributor.

                  E. If, after the Closing has occurred, but prior to the Option
Closing, Acquiror is in default with respect to, or breaches, or fails to
perform one or more of the representations, warranties, covenants or other terms
of this Agreement related to One City Centre and Three City Centre, and such
default, breach or failure is not cured or remedied within five (5) business
days prior to the Option Closing Date or otherwise waived by Contributor,
Contributor may terminate this Agreement with respect to One City Centre and
Three City Centre and, as its sole remedy, receive $100,000 from Acquiror, as
liquidated damages, and, upon such payment, the parties shall be released from
all further obligations and liabilities under this Agreement with respect to One
City Centre and Three City Centre, except with respect to the Surviving
Indemnities. 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 payment
stated above has been determined by the parties as a reasonable sum for damages
and is intended not as a penalty, but as full liquidated damages.

                  F. If, after the Closing has occurred, but prior to the Option
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 related to One City Centre and Three City Centre, and such


                                       63

<PAGE>

default, breach or failure is not cured or remedied within five (5) business
days prior to the Option Closing Date or otherwise waived by Acquiror, Acquiror
as its sole remedy may either (a) terminate this Agreement with respect to One
City Centre and Three City Centre, in which event Contributor shall pay Acquiror
$100,000 and, upon such payment, the parties shall be released from all further
obligations and liabilities under this Agreement with respect to One City Centre
and Three City Centre, except with respect to the Surviving Indemnities, or (b)
sue for specific performance. If Acquiror elects the remedy set forth in (a)
above, Contributor shall make such payment within fifteen (15) days after
Contributor's receipt of written notice from Acquiror. It is recognized by
Contributor and Acquiror that the damages Acquiror will sustain by reason of
Contributor's default, breach or failure will be substantial, but difficult, if
not impossible, to ascertain. The payment stated above has been determined by
the parties as a reasonable sum for damages and is intended not as a penalty,
but as full liquidated damages.

         15.      INDEMNIFICATION

                  A. Indemnification by Contributor. Subject to Section 15D of
this Agreement, after Closing (with respect to the Properties), the Second
Closing (with respect to Waterfront II), or the Option Closing (with respect to
One City Centre and Three City Centre), Michael J. Falcone and Michael P.
Falcone, jointly and severally, agree 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 reasonable 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 of Michael J. Falcone or any other Contributor contained in this
Agreement, or failure to perform or breach of any covenant or agreement on the
part of any Contributor contained in this Agreement, (ii) any dispute set forth
in Schedule 8A(x) attached to this Agreement, and (iii) any matters disclosed on
Schedules 8A(vi), (xvii), and (xxii)(1) attached to this Agreement in respect of
Waterfront II.

                  B. Indemnification by Acquiror. Subject to Section 15D of this
Agreement, after Closing, Acquiror agrees to indemnify the Contributor and its
partners, members, 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 failure to perform or breach of
any 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 15 will be asserted and resolved as
follows:

                        (i) If any claim or demand in respect of which an
         Indemnified Party might seek indemnity under this Section 15 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. 

                                       64

<PAGE>


         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 15 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
                  15C(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 15). 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
                  15 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 15C(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 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 

                                       65

<PAGE>

                  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 15 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 15 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 15C.

                       (ii) If any Indemnified Party should have a claim under
         this Section 15C 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 15 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 15C.

                      (iii) Any dispute submitted to arbitration pursuant to
         this Section 15C 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 

                                       66

<PAGE>

         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.

For purposes of this Section 15, the following terms shall have the meanings
ascribed to them below:

                  (1) "Claim Notice" shall mean written notification of a Third
Party Claim, pursuant to Section 15C(i), as to which indemnity under Section 15
is sought by an Indemnified Party, enclosing a copy of all papers served, if
any; and specifying the nature of and basis for such Third Party Claim and for
the Indemnified Party's claim against the Indemnifying Party under Section 15,
together with the amount or, if not then reasonably ascertainable, the estimated
amount, determined in good faith, of such Third Party Claim.

                  (2) "Dispute Period" shall mean the period ending thirty (30)
calendar days following receipt by an Indemnifying Party of either a Claim
Notice or Indemnity Notice.

                  (3) "Indemnified Party" shall mean any person or entity
claiming indemnification under any provision of Section 15.

                  (4) "Indemnifying Party" shall mean any person or entity
providing indemnification under any provision of Section 15.

                  (5) "Indemnity Notice" shall mean written notification
pursuant to Section 15C(ii) of a claim for indemnity under Section 15 by an
Indemnified party, specifying the nature of and basis for such claim, together
with the amount or, if not then reasonably ascertainable, the estimated amount,
determined in good faith, of such claim.

                  D. Except as otherwise provided in this Agreement, (i) neither
Contributor, on the one hand, nor Acquiror and the REIT, on the other hand,
shall have the right to bring a claim against the other by virtue of any of the
representations or warranties set forth herein being false or misleading unless
(a) such claim is brought on or prior to the date through which such
representation or warranty survives, (b) 

                                       67


<PAGE>

until notice of the false or misleading representation or warranty has been
given to the other party and such other party has had a reasonable period of
time to cure such false or misleading representation or warranty and (c) the
aggregate damages to the party bringing the claim for such false or misleading
representation or warranty are expected to exceed $750,000, but thereafter such
party may bring a claim against the other for the entire amount of its aggregate
damages not to exceed the Damages Cap (as defined below); and (ii) in no event
shall either Contributor, on the one hand, or Acquiror and the REIT, on the
other hand, have a liability to the other for any breach, inaccuracy,
incompleteness or non-fulfillment of any of the representations, warranties,
covenants or agreements set forth in this Agreement relating to such party in
excess of $50,000,000 in the aggregate (the "Damages Cap"). Notwithstanding the
foregoing, neither the limitation set forth in Section 15D(i)(c) nor the Damages
Cap shall apply to any liability arising from a breach of the representation and
warranty contained in Section 8A(xxv) and any such liability shall not be
aggregated with any other liabilities for the purpose of determining whether the
Damages Cap has been reached.

                  E. The indemnification provisions of this Section 15 shall,
notwithstanding anything contained herein to the contrary, be the sole and
exclusive remedy of Acquiror and Contributor, as against each other, with
respect to all matters or Losses arising under or relating to this Agreement,
including, without limitation, all Losses incurred under or relating to
Environmental Laws, under any form or theory of action whatsoever, whether in
contract, tort, statute or otherwise, including without limitation CERCLA and
comparable state and local statutes.

         16.      MISCELLANEOUS

                  A. Except as otherwise expressly set forth herein, this
Agreement shall not be cancelled or merged upon consummation of the Closing, the
Second Closing or the Option Closing, as the case may be. Each and every
representation and warranty of Contributor contained in this Agreement shall be
deemed to have been relied upon by Acquiror notwithstanding any investigation
Acquiror or its Representatives may have made with respect thereto or any
information developed by or made available to Acquiror prior to the Closing, the
Second Closing or the Option Closing, as the case may be. Each and every
representation and warranty of Acquiror and the REIT contained in this Agreement
shall be deemed to have been relied upon by Contributor notwithstanding any
investigation Contributor or its Representatives may have made with respect
thereto or any information developed by or made available to Contributor prior
to the Closing, the Second Closing or the Option Closing, as the case may be.

                  B. Neither this Agreement nor any interest hereunder shall be
assigned or transferred by Contributor. Acquiror may direct Contributor to
convey the Properties, Additional Properties or any part thereof to any party
designated by Acquiror, provided notice of such designation is given to
Contributor in writing at least ten (10) business days prior to Closing, the
Second Closing or the Option Closing, as the case may be, and that any such
designee is a directly or indirectly wholly-owned partnership subsidiary of
Acquiror or the REIT (a "Permitted Designee"). Subject to the foregoing, this
Agreement shall inure to the benefit of and shall be binding upon Contributor
and Acquiror and their respective successors and assigns.

                  C. This Agreement constitutes the entire agreement between
Contributor and Acquiror with respect to the Properties and Additional
Properties and shall not be modified or amended except in a written document
signed by Contributor and Acquiror. Any prior agreement or understanding between
Contributor and Acquiror concerning the Properties or Additional Properties is
hereby rendered null and void.

                  D. This Agreement constitutes an offer by Acquiror to
Contributor and shall not be 

                                       68

<PAGE>

effective until executed by each of Acquiror and Contributor. The date of this
Agreement shall be the date on which Acquiror signs this Agreement as indicated
below the signature line for Acquiror.

                  E. In the computation of any period of time provided for in
this Agreement or by law, the day of the act or event from which the period of
time runs shall be excluded, and the last day of such period shall be included,
unless it is a Saturday, Sunday or legal holiday, in which case the period shall
be deemed to run until the end of the next day which is not a Saturday, Sunday
or legal holiday.

                  F. This Agreement shall be governed and interpreted in
accordance with the laws of the State of New York, without giving effect to the
conflicts of laws principles thereof.

                  G. All notices, requests, demands or other communications
required or permitted under this Agreement shall be in writing and delivered

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
third day after the same is deposited with the United States Postal Service.
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 16G.

                  H. 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 Additional 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 December 31, 1997 for each Property and each Additional
Property; and (ii) prior to the expiration of the Inspection Period, Contributor
shall provide Acquiror with all data in their possession or control required to
perform depreciation allocations (as contemplated by Section 704(c) of the Code)
with respect to each Property, each Additional Property and each OP Unit
Recipient. Such data shall include the tax basis allocable to each OP Unit
Recipient for each Property and each Additional Property. In addition,
Contributor acknowledges that, if repayment of any of the Existing Indebtedness
other than 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.

                  I. 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, neither Acquiror nor Contributor will, and will not
permit any of their respective 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 the other, 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.

                  J. 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 

                                       70

<PAGE>

together as a single instrument. Execution copies of this Agreement may also be
exchanged by facsimile, and facsimile signatures shall be treated as originals.

                  K. 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.

                  L. 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.

                  M. 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.

                  N. The Properties and Additional 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 the
Closing, the Second Closing or the Option Closing, as the case may be. Except as
expressly set forth in this Agreement or in any document delivered by
Contributor at the Closing, the Second Closing or the Option Closing, as the
case may be, 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 and Additional
Properties.

other than to the Company, and shall take all such actions, consent to all such
arrangements and execute all such documents, as may be required by the Company
to ensure that the requirements of this sentence are met; provided, however,
that such Shares may be held jointly by Executive and Executive's wife if
Executive's wife agrees in a manner satisfactory to the Company (i) that the
terms of this sentence shall be applicable to her and (ii) to be bound by such
requirements. In addition to the Annual Bonus, Executive shall receive on each
of the first three anniversaries of the date hereof an additional bonus, for so
long as he continues to be employed hereunder, each in an amount equal to
$33,333.33 (or, if lower, the then-remaining amount of principal outstanding, if
any); provided that (i) the Company may retain each such additional bonus in
satisfaction of and as an offset to Executive's obligations under the loan and
(ii) without limiting the generality of Section D, Paragraph 5 hereof, the
Company may require Executive to pay to the Company at the time of the payment
of any such additional bonus the amount the Company in good faith deems
necessary to satisfy the Company's obligation to withhold federal, state or
local income or other taxes incurred by reason of such additional bonus (it
being expressly agreed that, notwithstanding the foregoing, Executive's
satisfaction of any tax-withholding requirements so imposed by the Company is a
condition precedent to the Company's obligation to pay each such additional
bonus). Notwithstanding the foregoing, the outstanding balance of the above
loan, if not earlier due, shall become due and payable 120 days after
Executive's Employment Term has terminated for any reason, other than an
Involuntary Termination or a Termination Without Cause. If the outstanding loan
balance becomes due and payable under the preceding sentence, and is not timely
repaid, then the outstanding loan balance shall thereupon begin to accrue
interest at The Wall Street Journal prime rate as used by First Union
Corporation (including its subsidiaries) in connection with mortgage loans made
thereby (or such other rate as is used thereby for such purposes), plus three
percentage points, compounded monthly.

                  (d) Executive shall be entitled to full and complete
participation in the Company's Salary Reduction and Other Elective Simplified
Employee Pension-Individual Retirement Account Contribution Agreement as
documented on Form 5305A-SEP, to the extent in effect from time to time.

                  (e) In addition, the Company may from time to time pay
Executive such compensation or benefits as the Compensation Committee of the
Board may, in its discretion, award to Executive under any compensation, bonus,
stock purchase, stock option, profit sharing or other employee benefit plan that
may hereafter be adopted (any such compensation is referred to as "Incentive
Compensation"). Executive's Incentive Compensation will be consistent with the
Incentive Compensation available to other similarly situated senior executives
of the Company.


<PAGE>


                  (f) Without limiting the generality of Paragraph 3(e),
effective as of the date hereof, Executive shall be granted an option (the
"Option") to purchase 50,000 shares of common stock of the Company at an
exercise price equal to the fair market value at such time. To the extent that
there has been no termination of Executive's employment and the Option has not
otherwise expired, one third of the shares subject to the Option shall vest
immediately upon grant, with an additional one third of the shares subject to
the Option to vest on each of the following two anniversaries of the date of
grant. The Option shall be subject to a definitive option award agreement
containing such other terms and conditions (including without limitation
provisions relating to termination of employment, method of exercise and
payment, withholding and nontransferability) as the Board determines in its sole
discretion which are not inconsistent with the foregoing provisions of this
Paragraph 3(f).

                  4. Benefits. The Company agrees to provide Executive with the
following benefits during the Employment Term:

                           (a) Vacation. Executive shall be entitled each year
to a paid vacation in accordance with the practices of the Company as
constituted by the Board.

                           (b) Employee Benefits. Executive shall be entitled to
all rights, benefits and privileges to which other management level employees of
the Company are entitled, including, but not limited to, any retirement,
pension, profit sharing, insurance, hospital or other plans which may now be in
effect or which may hereafter be adopted by the Company.

                  5. Expenses. The Company recognizes that Executive will have
to incur certain out-of-pocket expenses, including, but not limited to, travel
expenses, related to his services and the Company's business, and the Company
agrees to reimburse Executive for all reasonable expenses necessarily incurred
by him in the performance of his duties upon presentation of a voucher or
documentation reasonably acceptable to the Company indicating the amount and
business purposes of any such expenses. In addition, the Company shall reimburse
Executive, upon Executive's submission of proof of such expenses, for the
following costs of relocating from Smyrna, Georgia to the Villanova,
Pennsylvania area: direct costs associated with (i) the sale of Executive's
current residence, located in Smyrna, Georgia (excluding any loss that may have
been incurred in connection therewith), (ii) the purchase of a new residence
within the Villanova, Pennsylvania area (excluding the actual price of the
residence), (iii) the provision of temporary housing, for up to three months,
(iv) searching for a new residence, (v) the actual moving from Smyrna, Georgia
to the Villanova, Pennsylvania area and (vi) obtaining a new mortgage loan
(excluding any interest-related costs, but including "points" up to three
points). In the event Executive incurs federal, state or local income taxes
attributable to the Company's bearing such moving expenses, the Company shall
pay Executive an additional payment sufficient to offset any such income taxes
(excluding any interest or penalties) and any such income taxes imposed by
reason of such payment.

                  6. Termination in Case of Death or Disability. In case of
Executive's death or permanent disability (defined as physical or mental
inability, confirmed by a licensed physician, to 


<PAGE>


perform substantially all of the services described herein that continues for a
period of 180 consecutive or non-consecutive days in any 365-day period), the
Company may elect to terminate Executive pursuant to the terms of Section B,
Paragraph 8 hereof.

                  7. Termination With Cause; Voluntary Termination. The Company
may terminate this Agreement upon a determination that an event has occurred
within the definition of Termination With Cause; provided, however, in the case
of a Termination With Cause based upon clauses (a) or (b) of such definition,
the Company shall provide Executive written notice of such grounds for
termination. If Executive shall suffer Termination With Cause or shall cease
being an employee of the Company on account of a Voluntary Termination, then (i)
Executive shall not be entitled to any compensation after the effective date of
such Voluntary Termination or Termination With Cause (except compensation
accrued but unpaid on the date of such event); (ii) any continued rights and
benefits Executive may have under employee benefit plans and programs of the
Company upon such a termination, if any, shall be determined in accordance with
the terms of such plans and programs; and (iii) Executive shall have no further
rights to any other compensation or benefits hereunder or granted hereunder on
or after the termination of employment, or any other rights hereunder.

                  8. Termination Upon Death or Disability. Upon death or other
termination of employment by virtue of disability, then (i) Executive shall not
be entitled to any compensation after the effective date of such termination
(except compensation accrued but unpaid on the date of such event); (ii) all
outstanding unvested Options granted under Paragraph 3(f) shall vest and shall
otherwise be exercisable in accordance with their terms; and (iii) Executive
shall have no further rights to any other compensation or benefits hereunder or
granted hereunder on or after the termination of employment, or any other rights
hereunder. Any continued rights and benefits that Executive, or Executive's
estate or other legal representatives, may have under employee benefit plans and
programs of the Company upon such death or disability shall be determined in
accordance with the terms and provisions of such plans and programs.

                  9. Involuntary Termination or Termination Without Cause. (a)
If Executive shall suffer an Involuntary Termination or a Termination Without
Cause, then (i) the Company shall pay Executive cash compensation in a lump sum
equal to (A) Executive's base salary (based on Executive's base salary at the
time of such termination) plus (B) the prior year's Annual Bonus under Paragraph
3(b) or, if greater, $100,000 (except as set forth in Section B, Paragraph 10
hereof); (ii) the Company shall continue to provide, for the longer of one year
or the remainder of the Employment Term, Executive with the level of
health/medical insurance or coverage provided to Executive at the time of such
termination; it being expressly understood and agreed that nothing in this
clause (ii) shall restrict the ability of the Company to amend or terminate such
plans and programs from time to time in its sole discretion; provided, however,
that the Company shall in no event be required to provide any coverage after
such time as Executive becomes entitled to receive benefits of the same type
from another employer or recipient of Executive's services (and provided,
further, that such entitlement shall be determined without regard to any
individual waivers or other similar arrangements); (iii) all outstanding
unvested Options granted under Paragraph 3(f) shall vest and shall otherwise be
exercisable in accordance with their terms; (iv) subject to Executive's
satisfaction of any tax-withholding obligations as contemplated by Section B,
Paragraph 3(c) hereof, the Company shall forgive $300,000 of the loan made by
the Company to Executive under 


<PAGE>


Section B, Paragraph 3(c) hereof (or, if lower, the outstanding balance
thereof); and (v) except as provided in Section B, Paragraph 10, Executive shall
have no further rights to any other compensation or benefits hereunder or
granted hereunder on or after the termination of employment, or any other rights
hereunder. Any continued rights and benefits that Executive may have under
employee benefit plans and programs of the Company upon such termination shall
be determined in accordance with the terms and provisions of such plans and
programs.

                  (b) Notwithstanding the foregoing, (i) neither Good Reason nor
grounds for Involuntary Termination shall be deemed to exist unless written
notice of termination on account thereof (specifying a termination date no less
than 14 days and no more than 21 days from the date of such notice) is given no
later than 90 days after the time at which the event or condition purportedly
giving rise to Good Reason or the Involuntary Termination first occurs or
arises; and (ii) if there exists (without regard to this clause (ii)) an event
or condition that constitutes Good Reason or grounds for Involuntary
Termination, the Company shall have 14 days from the date notice of such a
termination is given to remedy or cure such event or condition and, if the
Company does so, such event or condition shall not constitute Good Reason or
grounds for Involuntary Termination, respectively, hereunder.

                  10. Termination Upon a Change in Control. If, within the
one-year period to follow a Change in Control, Executive shall suffer a
termination other than by reason of death or disability or a Termination With
Cause, then, in lieu of the amount provided for under clause (i) of the first
sentence of Section B, Paragraph 9 hereof, Executive shall receive two times
such amount, and, in addition to such other payments and benefits as may be
provided for under Section B, Paragraph 9 hereof, (i) any and all outstanding
unvested options held by Executive shall vest and become immediately exercisable
otherwise in accordance with their terms and (ii) subject to Executive's
satisfaction of any tax-withholding obligations as contemplated by Section B,
Paragraph 3(c) hereof, the Company shall forgive the outstanding balance on the
loan made by the Company to Executive under Section B, Paragraph 3(c) hereof.

                  11. Indemnification. The Company agrees that for the
Employment Term, provisions of the Company's bylaws regarding indemnification
and advancement of expenses of officers and directors shall not be amended to
adversely effect Executive nor shall the Company's articles of incorporation be
amended to adversely effect Executive's rights with respect to limitation of
liability, indemnification or advancement of expenses.

                  C.       AGREEMENT NOT TO COMPETE

                  Except as explicitly provided herein, Executive agrees, for
the entire Employment Term and Noncompetition Period, to the following
covenants, effective within the United States:

                  1. Competitive Activity Restriction. Executive, personally or
through any Affiliate of Executive, shall not conduct any Competitive Activity
other than through the Company, unless a majority of the Board, which majority
must include a majority of the Independent Directors, have determined that such
Competitive Activity will not have a material adverse effect on the business or
operations of the Company. Notwithstanding any other provision of this
Agreement, and without limiting any obligations to the Company that Executive
may have without 


<PAGE>


regard hereto, Executive agrees that, during the time he is employed by the
Company, Executive shall present to the Company all opportunities that arise to
engage in Competitive Activities unless Executive reasonably determines that
such opportunities are not appropriate for the Company.

                  2. No Beneficial Ownership. Executive shall not beneficially
own directly or indirectly any beneficial interest in any entity engaged in any
Competitive Activity other than the Company, except for any interest in a
company traded on a nationally recognized public securities exchange (including
The Nasdaq National Market), provided such interest does not exceed 5% of the
outstanding capital stock of such company.

                  3. Loans. Executive shall not directly or indirectly make any
loan to, or hold any note evidencing a loan from, any entity engaged in any
Competitive Activity.

                  4. Competitive Entity. Executive shall not be a director or
trustee, partner, officer, principal, agent or employee of, or consultant to
(whether for compensation or not), or work in any other capacity for, any entity
engaged in any Competitive Activity.

                  5. Notification to Independent Directors. If Executive or any
Affiliate of Executive desires to engage in any Competitive Activity, Executive
shall describe fully the proposed activity in a written notice (the "Disclosure
Notice") to the Company and the Independent Directors. A Disclosure Notice shall
only pertain to a specific proposed project and the referenced proposed project
shall be described therein with specificity as to timing, location, scope and
the extent of Executive's involvement, financially and in terms of his time
commitment. A Disclosure Notice may not request approval for any conceptual or
non-project specific activity or for any activity that is prohibited by this
Agreement.

                  6. Confidential Information. Executive shall keep secret and
retain in strictest confidence, and shall not use for his benefit or the benefit
of others, except in connection with the business and affairs of the Company and
its Affiliates, all confidential matters relating to the Company's business and
the business of any of its Affiliates, learned by Executive heretofore or
hereafter directly or indirectly from the Company or any of its Affiliates (the
"Confidential Company Information"), including, without limitation, information
with respect to (i) sales figures (whether per property or otherwise), (ii)
profit or loss figures (whether per property or otherwise), and (iii) customers,
clients, tenants, and customer lists; and shall not disclose such Confidential
Company Information to anyone outside of the Company except with the Company's
express written consent and except for Confidential Company Information which is
at the time of receipt or thereafter becomes publicly known through no wrongful
act of Executive's or is received from a third party not under an obligation to
keep such information confidential and without breach of this Agreement.

                  7. No Interference or Solicitation. Notwithstanding any other
provision of this Agreement, during the Noncompetition Period, Executive shall
not directly or indirectly (i) solicit or endeavor to entice away any existing
client of the Company or any potential client of the Company whom the Company
was actively soliciting during the time of Executive's directorship, or any
person who during the Employment Term or the one-year period which follows the
expiration of the Employment Term was or is a client of the Company, (ii) hire,
solicit or otherwise 


<PAGE>


encourage any employee or independent contractor of the Company to leave the
employment of, or terminate any contractual relationship with, the Company, or
(iii) hire any employee or independent contractor who has left the employment or
other service of the Company or any of its Affiliates within the six-month
period which follows the termination of such employee's or independent
contractor's employment or other service with the Company and its Affiliates, or
(iv) otherwise interfere with, disrupt or attempt to disrupt the relationships,
contractual or otherwise, between the Company and its employees or independent
contractors or solicit or encourage any employee or independent contractor of
the Company to engage in any Competitive Activity.

                  8. Return of Property. All memoranda, notes, lists, records,
property and any other tangible product and documents (and all copies thereof),
whether visually perceptible, machine-readable or otherwise, made, produced or
compiled by Executive or made available to Executive concerning the business of
the Company or its Affiliates, (i) shall at all times be the property of the
Company (and, as applicable, any Affiliates) and shall be delivered to the
Company at any time upon its request, and (ii) upon Executive's termination of
employment, shall be immediately returned to the Company; provided, however,
that Executive may retain a copy of his "rolodex" (or other similar record of
names and addresses) maintained from time to time in the ordinary course.

                  D.       MISCELLANEOUS PROVISIONS.

                  1. Notices. All notices or deliveries authorized or required
pursuant to this Agreement shall be deemed to have been given when in writing
and when (i) deposited in the U.S. mail, certified, return receipt requested,
postage prepaid, or (ii) otherwise delivered by hand or by overnight delivery,
against written receipt, by a common carrier or commercial courier or delivery
service addressed to the parties at the following addresses or to such other
addresses as either may designate in writing to the other party:

                  To Executive:      Timothy A. Peterson,

                  2. Entire Agreement. This Agreement contains the entire
understanding between the parties hereto with respect to the subject matter
hereof and shall not be modified in any manner except by written instrument
signed by or on behalf of the parties hereto. This Agreement shall be binding
upon and inure to the benefit of the heirs, successors and assigns of the
parties hereto.

                  3. Applicable Law. THIS AGREEMENT SHALL BE GOVERNED AND


<PAGE>


CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA.

                  4. Assignment. Executive acknowledges that his services are
unique and personal. Executive may not assign his rights or delegate his duties
or obligations under this Agreement except (a) his rights to compensation and
benefits hereunder may be transferred by will or operation of law and (b) his
rights under employee benefit plans or programs described in Section B,
Paragraph 4(b) may be assigned or transferred in accordance with the terms of
such plans or programs, or regular practices thereunder. Executive's rights and
obligations under this Agreement shall inure to the benefit of and shall be
binding upon Executive's heirs and personal representatives.

                  5. Withholding. The Company shall be entitled to withhold from
any payments or deemed payments any amount of tax withholding required by law.

                  6. Titles and Headings. Titles and headings to sections and
paragraphs in this Agreement are inserted for the convenience of reference only
and are not intended to be a part of or to affect the meaning or interpretation
of this Agreement.

                  7. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

                  8. Amendments. No amendment, modification, waiver or
supplement to this Agreement shall be binding on any of the parties hereto
unless it is in writing and signed by the parties in interest at the time of the
modification, and further provided any such modification is approved by a
majority of the Independent Directors. No delay on the part of any party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party of any such right, power
or privilege nor any single or partial exercise of any such right, power or
privilege, preclude any other or further exercise thereof or the exercise of any
other such right, power or privilege.

                  9. No Third-Party Beneficiaries. This Agreement is solely for
the benefit of the parties to this Agreement and should not be deemed to confer
upon third parties any remedy, claim, liability, reimbursement, claims or action
or other right in excess of those existing without reference to this Agreement.

                  10. Maximum Legal Enforceability; Time of Essence. Any
provision of this Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof. Any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other
jurisdiction. Without prejudice to any rights or remedies otherwise available to
any party to this Agreement, each party hereto acknowledges that damages would
not be an adequate remedy for any breach of the provisions of this Agreement and
agrees that the obligations of the parties hereunder shall be specifically
enforceable. Time shall be of the essence as to each and every provision of this
Agreement.


<PAGE>


                  11. Specific Performance. (a) Executive acknowledges that the
obligations undertaken by him pursuant to this Agreement are unique and that the
Company will not have an adequate remedy at law if he shall fail to perform any
of his obligations hereunder, and Executive therefore confirms that the
Company's right to specific performance of the terms of Section C of this
Agreement is essential to protect the rights, interest and goodwill of the
Company. Accordingly, in addition to any other remedies that the Company may
have at law or in equity, the Company shall have the right to have all
obligations, covenants, agreements and other provisions of Section C of this
Agreement specifically performed by Executive, and the Company shall have the
right to obtain preliminary and permanent injunctive relief to secure specific
performance and to prevent a breach or contemplated breach of Section C of this
Agreement by Executive. Executive acknowledges that the Company will have the
right to have the provisions of Section C of this Agreement enforced in any
court of competent jurisdiction, it being agreed that any breach or threatened
breach of Section C of this Agreement would cause irreparable injury to the
Company and its business and that money damages would not provide an adequate
remedy to the Company.

                  (b) Any controversy or claim arising out of or relating to
this Agreement or the breach of this Agreement that is not resolved by Executive
and the Company (or its Affiliates, where applicable), other than controversies
or claims arising under Section C, to the extent necessary for the Company (or
its Affiliates, where applicable) to avail itself of the rights and remedies
provided under Section D, Paragraph 11(a) hereof, shall be submitted to
arbitration in Philadelphia, Pennsylvania in accordance with Pennsylvania law
and the procedures of the American Arbitration Association. The determination of
the arbitrator(s) shall be conclusive and binding on the Company (or its
Affiliates, where applicable) and Executive and judgment may be entered on the
arbitrator(s)' award in any court having jurisdiction.

                  12. Survival. Anything contained in this Agreement to the
contrary notwithstanding, the provisions of Section C hereof, Section D,
Paragraphs 5 and 11 hereof, and the other provisions of this Section D (to the
extent necessary to effectuate the survival of Section C and Section D,
Paragraphs 5 and 11), shall survive termination of this Agreement and any
termination of Executive's employment hereunder.

                  13. Operations of Affiliated Parties. Executive agrees that he
will refrain from authorizing any Affiliate to perform any activities that would
be prohibited by the terms of this Agreement if they were performed by him.
Notwithstanding anything to the contrary contained in this Agreement, Executive
shall not be required by the terms of this Agreement to violate any fiduciary
duty existing on the date hereof that he owes to a third party.

                  14. Existing Agreements. Executive represents to the Company
that he is not subject or a party to any employment or consulting agreement,
non-competition covenant or other agreement, covenant or understanding which
might prohibit him from executing this Agreement or limit his ability to fulfill
his responsibilities hereunder.

                  15. Parachutes. If all, or any portion, of the payments
provided under this Agreement, either alone or together with other payments and
benefits which Executive receives or is entitled to receive from the Company or
an affiliate, would constitute an excess "parachute 


<PAGE>


payment" within the meaning of Section 280G of the Code (whether or not under an
existing plan, arrangement or other agreement) (each such parachute payment, a
"Parachute Payment"), and would result in the imposition on Executive of an
excise tax under Section 4999 of the Code, then, in addition to any other
benefits to which Executive is entitled under this Agreement, Executive shall be
paid by the Company an amount in cash equal to the sum of the excise taxes
payable by Executive by reason of receiving Parachute Payments plus the amount
necessary to put Executive in the same after-tax position (taking into account
any and all applicable federal, state and local excise, income or other taxes at
the highest possible applicable rates on such Parachute Payments (including
without limitation any payments under this Paragraph 15) as if no excise taxes
had been imposed with respect to Parachute Payments (the "Parachute Gross-up")).
Except as may otherwise be agreed to by the Company and Executive, the amount or
amounts (if any) payable under this Paragraph 15 shall be as conclusively
determined by the Company's independent auditors (who served in such capacity
immediately prior to a Change in Control (or, if applicable, a change in control
which is not a Change in Control)). If such independent auditors refuse to make
the required determinations, then such determinations shall be made by a
comparable independent accounting firm of national reputation selected by the
Company and reasonably acceptable to Executive.

                  16. Further Assurances. The parties to this Agreement will
execute and deliver or cause the execution and delivery of such further
instruments and documents and will take such other actions as any other party to
the Agreement may reasonably request in order to effectuate the purpose of this
Agreement and to carry out the terms hereof.


                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed as of the day and year first written above.

FOR IMMEDIATE RELEASE

American Real Estate Investment Corporation Hires Chief Financial Officer

PLYMOUTH MEETING, Penn., August 10 /PRNewswire/ -- American Real Estate
Investment Corporation (the "Company") (AMEX: REA) announced today that Timothy
A. Peterson will join the firm as its Senior Vice President and Chief Financial
Officer. In his role as the Company's Chief Financial Officer, Mr. Peterson will
report directly to Jeff Kelter, American Real Estate's President, and will

reporting, budgeting and systems functions.

Prior to joining the Company, Mr. Peterson was employed by Post Properties,
Inc., where he has held a variety of positions since 1989, including his current
