ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On December 15, 1999, Keystone Property Trust ("Keystone"), through Keystone
Operating Partnership, L.P. (the "Operating Partnership"), a limited partnership
of which Keystone is the sole general partner and in which Keystone owns an
interest of approximately 55.5% after the consummation of the transaction
discussed herein, announced in a press release attached hereto as Exhibit 99.1
and incorporated herein by reference, the acquisition on December 15, 1999 of
407,100 square foot bulk distribution warehouse located in Carlisle, PA for
approximately $16.0 million (the "Roadway Property"). The purchase price was
funded through the issuance of $1.4 million in Operating Units from the
Operating Partnership valued at $15.26 per unit, a $12.0 million 6-year term
loan from the Prudential Insurance Company of America and cash payments of
approximately $2.5 million. The Roadway Property was constructed in 1988 and is
fully leased to Dana Corporation under a lease that expires in February, 2009.
The Roadway Property has an 8-acre pad site which is fully entitled for a
150,000 square foot expansion.

The Roadway Property was purchased from a private investment partnership
controlled by Jeffrey E. Kelter, Keystone's President and Chief Executive
Officer and certain other employees of the Company. An affiliate of Keystone has
managed the building since its purchase in January 1997. The terms of the
acquisition were approved by a special subcommittee of Keystone Property Trust's
Board of Directors formed specifically to review this related-party transaction.
The Company based its determination of the purchase price of these properties on
the expected cash flow, physical condition, location, competitive advantages,
existing tenancies, and opportunities to retain and attract tenants.

                               (xv)  The current zoning classification of the
Real Property under the Zoning Code of the Township of Middlesex and to Owners'
knowledge, the use of the buildings and other improvements constituting the Real
Property do not violate the Zoning Code.

                               (xvi)  Seller has no knowledge of any defective
condition, structural or otherwise, with respect to the Improvements.

                               (xvii) To Owners' knowledge, all real estate
taxes currently due and payable with respect to the Real Property have been
paid; the Real Property constitutes separate tax parcels and are separately
assessed for real estate tax purposes; and there is no proceeding pending for
the adjustment of the assessed valuation of all or any portion of the Property.

                               (xviii) Owners have not received any notice of
any condemnation proceeding or other proceedings in the nature of eminent domain
("Taking") in connection with the Property, and to Seller's knowledge no Taking
has been threatened.

                               (xix)   Except as otherwise set forth in that
certain Environmental Survey dated December 1, 1998 from EMG to the Partnership,
Owners represent and warrant to Assignee that to the best of Owners' knowledge:

                                            (A) No notice has been issued to the

                                            (B) The Partnership has not
generated, stored, treated, disposed of, discharged, released, emitted or
otherwise handled any Contaminant on, over, under, from or in any manner
affecting the Real Property. For the purposes of this subsection (B) only,

customarily used or stored incidental to and are reasonably necessary for the

Laws or Contaminants on, over, under, from or affecting the Real Property.

                               (xx) To the extent that any broker engaged by
Owners is entitled to any commission for the transactions contemplated by this
Agreement, Owners shall pay all such commissions and shall indemnify, defend and
save and hold harmless Assignee of and from the obligation to pay any such
commissions.

                               As used in this Section 7.A, "knowledge" shall
mean the "actual" knowledge of Kelter or Butte; provided, however, that such
parties shall be deemed to have "actual" knowledge of an occurrence or event to
the extent the Partnership, or any of such parties, has received written
notification of such an occurrence or event.

                               At Closing, Owners shall deliver to Assignee a
Certificate signed by Owners updating to the Closing Date the foregoing
representations and warranties, and disclosing in such Certificate any changes
of circumstance or variations or exceptions to the foregoing representations and
warranties existing as of the Closing Date.

                  B. REPRESENTATIONS, WARRANTIES AND COVENANTS OF OWNERS WITH
RESPECT TO PARTNERSHIP INTERESTS. Each Owner represents, warrants and covenants
to Assignee, for itself only and not on behalf of any other Owner, that the
following are true, complete and correct as of the date of this Agreement:

                               (i) Such Owner's Partnership Interest is owned by
such Owner free and clear of all liens, encumbrances and rights of every kind,
and such Owner has the right to assign and transfer such Partnership Interest to
GP Assignee and Assignee. To such Owner's knowledge, no person has asserted any
claims in respect of, or claimed any interest in, such


                                      -19-

<PAGE>

Owner's Partnership Interest, and no consent of any third party is needed in
order for such Owner to consummate this transaction.

                               (ii) Such Owner has not received any notice from
any governmental authority of any ongoing or proposed audit or investigation
relating to the Tax Returns.

                               (iii) There are no contracts, agreements or
commitments, written or oral, to which such Owner is a party affecting such
Owner's Partnership Interest which would be binding upon Assignee or the
Partnership subsequent to Closing.

                               (iv) Such Owner has not received any written
notice which remains outstanding of any action, proceeding or investigation
pending or threatened against such Owner before any court or governmental
department, commission, board, agency or instrumentality that can materially
affect the consummation of the transactions contemplated hereby.

                               (v)  Such Owner has full power and authority to
enter into and fully perform and comply with the terms of this Agreement and,
other than with respect to any Owner who is an individual, such Owner is duly
organized, validly existing and qualified and empowered to conduct its business.
Neither the execution and delivery of this Agreement nor its performance by such
Owner will conflict with or result in the breach of any contract, agreement,
law, rule or regulation to which such Owner is a party or by which such Owner is
bound. This Agreement is valid and enforceable against such Owner in accordance
with its terms and each instrument to be executed by such Owner pursuant to this
Agreement or in connection herewith will, when executed and delivered, be valid
and enforceable against such Owner in accordance with its terms.

                               (vi) Such Owner is not and is not acting on
behalf of an "employee benefit plan" within the meaning of Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), a "plan"
within the meaning of Section 4975 of the Internal Revenue Code of 1986, as
amended (the "CODE"), or an entity deemed to hold "plan assets" within the
meaning of 29 C.F.R. Section 2510.3-101 of any such employee benefit plan or
plans; neither the Partnership Interest of such Owner, nor the Property,
constitute "plan assets" within the meaning of 29 C.F.R. Section 2510.3-101; and
the transfer of such Owner's Partnership Interests, and the consummation of the
transactions contemplated by this Agreement, shall not constitute a prohibited
transaction under Section 406(a)(1) of ERISA or 4975(c)(1)(A) - (c)(1)(D) of the
Code that is not exempt by operation of statute or by operation of a class-wide
prohibited transaction exemption issued by the U.S. Department of Labor.

                               (vii) Except as otherwise provided herein for the
benefit of Assignee, such Owner shall not, until expiration of the Put Option
provided the Remaining Partnership Interests have not theretofore been
transferred and conveyed to Assignee, sell,


                                      -20-

<PAGE>

transfer, contribute, convey, pledge or encumber its/his Remaining Partnership
Interests, or any portion thereof.

                               As used in this Section 7.B, "knowledge" shall
mean the "actual" (and not constructive) knowledge of such Owner; provided,
however, that such Owner shall be deemed to have "actual" knowledge of an
occurrence or event to the extent such Owner has received written notification
of such an occurrence or event.

                  C. REPRESENTATIONS AND WARRANTIES OF ASSIGNEE. Assignee
represents and warrants to Owners that the following are true, complete and
correct as of the date of this Agreement and as of the Closing:

                               (i) Assignee is duly organized, validly existing,
in good standing and qualified and empowered to conduct its business, and has
full power and authority to enter into and fully perform and comply with the
terms of this Agreement. Neither the execution and delivery of this Agreement
nor its performance by Assignee, will conflict with or result in the breach of
any material contract, agreement, law, rule or regulation to which Assignee is a
party or by which Assignee is bound.

                               (ii) This Agreement is valid and enforceable
against Assignee in accordance with its terms and each instrument to be executed
by Assignee pursuant to this Agreement or the Registration Rights Agreement, or
in connection herewith or therewith, will, when executed and delivered, be valid
and enforceable against Assignee in accordance with its terms.

                               (iii) Upon Closing, Assignee shall deliver to the
respective OP Unit Sellers good and marketable title to the Initial OP Units
free and clear of all liens, claims, encumbrances, and restrictions, except as
contained in this Agreement, the Registration Rights Agreement and the
Assignee's Partnership Agreement.

                               (iv) The capitalization of the Assignee is as set
forth in the Assignee's Partnership Agreement. There are no restrictions on the
transfer of the OP Units to be issued hereunder other than those contained
herein and in the Assignee's Partnership Agreement and the Registration Rights
Agreement, and those arising from federal and applicable state securities laws.
All OP Units issued and outstanding in accordance with the terms of this
Agreement are or will be duly authorized and validly issued in accordance with
the terms of the Assignee's Partnership Agreement and in compliance with
applicable laws and are exchangeable into cash or Common Shares of AREIC as
provided in the Assignee's Partnership Agreement. If and when issued, the Common
Shares issuable upon exchange of the OP Units will be duly authorized, validly
issued, fully paid and non-assessable. At the Closing, upon receipt of the
Initial Partnership Interests, the Assignee will have transferred the Initial OP
Units free and clear of all


                                      -21-

<PAGE>

liens and the OP Unit Sellers will be admitted as limited partners of Assignee.
The issuance of the Initial OP Units to the OP Unit Sellers at Closing will not
require any approval or consent of any person or entity except any such approval
that shall have been obtained on or prior to Closing.

                  D. REPRESENTATIONS AND WARRANTIES OF AREIC. By signing this
Agreement as General Partner of Assignee, AREIC represents and warrants to
Owners that the following are true, complete and correct as of the date of this
Agreement and as of the Closing:

                               (i) AREIC is duly organized, validly existing, in
good standing and qualified and empowered to conduct its business, and has full
power and authority to enter into and fully perform under this Agreement and the
Registration Rights Agreement. Neither the execution and delivery of this
Agreement and the Registration Rights Agreement, nor the performance of AREIC's
obligations hereunder and thereunder, will conflict with or result in the breach
of any material contract, agreement, law, rule or regulation to which AREIC is a
party or by which AREIC is bound.

                               (ii) In the limited capacity in which this
Agreement is executed by AREIC, this Agreement is valid and enforceable against
AREIC in accordance with its terms and each instrument to be executed by AREIC
pursuant to this Agreement or the Registration Rights Agreement, or in
connection herewith or therewith, will, when executed and delivered, be valid
and enforceable against AREIC in accordance with its terms.

                               (iii) AREIC will elect to be taxed as a real
estate investment trust for its taxable year ending December 31, 1998 and AREIC
is organized and will be operated in such a manner as to qualify for taxation as
a "real estate investment trust" as defined in Section 856 of the Code for at
least the taxable years ending December 31, 1998 and December 31, 1999.

                               (iv) To AREIC's knowledge, there are no pending
or threatened actions, suits or proceedings against or affecting AREIC at law or
in equity or before or by any governmental entity which would prevent or impair
the transactions contemplated hereby.

                  (E) CONDITIONS OF ASSIGNEE'S OBLIGATIONS.

                               (i) The obligations of Assignee under this
Agreement are subject to the satisfaction at the time of Closing of each of the
following conditions (any one of which may be waived in whole or in part in
writing by Assignee at or prior to Closing):

                                    (A) all of the representations and
warranties by Owners set forth in this Agreement shall be true and correct;


                                      -22-

<PAGE>

                                    (B) no representation or warranty by Owners
contained in this Agreement shall contain any untrue statement or shall omit a
material fact necessary to make the statement of fact therein recited not
misleading;

                                    (C) Owners shall have performed all
covenants, agreements and conditions required by this Agreement to be performed
by Owners prior to or as of the Closing Date;

                                    (D) Buyer shall have received the executed

                                    (E) There shall have been no material
adverse change in the condition of the Real Property, except to the extent
otherwise provided in Section 6 above.

                               (ii) In the event any of the conditions set forth
in Section 8(E) are not satisfied as of the Closing Date, Assignee shall have
the right (in addition to all other rights and remedies available to Assignee
under this Agreement, at law or equity), at Assignee's sole option (by written
notice to Owners) to (i) terminate Assignee's obligations under this Agreement,
or (ii) complete Closing notwithstanding the unsatisfied condition.

         8.       SURVIVAL.

                  The warranties, representations and covenants of Owners,
Assignee and AREIC set forth in this Agreement shall survive the execution and
delivery of this Agreement and the Closing.

         9.       LENDER RELEASE

                  Assignee shall use its best efforts to obtain the Release from
the holders of the Existing Mortgages and to deliver the Release to Owners at
Closing. In the event that Assignee does not cause the Existing Mortgage Debt to
be repaid on the Closing Date and Assignee has not delivered the Release to
Owners, Assignee shall deliver to Owners an Indemnity Agreement in form and
content reasonably acceptable to Owners and Assignee and their respective
counsel, pursuant to which AREIC and Assignee shall agree to indemnify, defend
and save and hold harmless Owners with respect to any loss, liability, cost or
expense (including counsel fees and court costs) which Owners may incur from and
after the Closing Date by reason of any liability for the Existing Mortgage Debt
and/or pursuant to the terms and provisions of any of the Existing Mortgages.


                                      -23-

<PAGE>

         10.      TERMINATION. To the extent that either Owners or Assignee
exercises its right to terminate this Agreement as expressly set forth above in
this Agreement, such party or parties shall exercise such right of termination
by giving written notice of such exercise to the other party or parties and,
upon the giving of such notice of termination, this Agreement shall terminate
and neither party shall have any further rights or obligations under this
Agreement.

         11.      DEFAULTS AND REMEDIES

                  Subject to the limitations contained elsewhere in this
Agreement, (a) Assignee may proceed directly against each Owner in order to
satisfy a claim or judgment made or obtained by Assignee due to the breach of
any representation, warranty, covenant or agreement made by such Owner in this
Agreement or any document, agreement, instrument or certificate delivered
pursuant to the terms of this Agreement; (b) Owners may proceed directly against
Assignee in order to satisfy a claim or judgment made or obtained by Owners due
to the breach of any representation, warranty, covenant or agreement made by
Assignee in this Agreement, or in order to satisfy any claim for indemnification
made by Assignee pursuant to any indemnification obligation of Assignee provided
for in this Agreement or any document, agreement, instrument or certificate
delivered pursuant to the terms of this Agreement; and (c) Owners may proceed
directly against AREIC in order to satisfy a claim or judgment made or obtained
by Owners due to the breach of any representation or warranty made by AREIC in
this Agreement or any document, agreement instrument or certificate delivered

         12.      TAX PROTECTION PROVISIONS

                  A. Assignee agrees that, following the Closing: (i) the
Partnership will not sell or otherwise dispose of the Property in a transaction
in which taxable gain is recognized for a period of two years after the Closing
Date (such period following the Closing Date being referred to herein as the
"TAX PROTECTION PERIOD"), except that the Partnership may sell the Property in
connection with a tax deferred exchange transaction entered into pursuant to
Section 1031 of the Code pursuant to which no taxable gain is recognized by any
Owner; and (ii) if the Partnership intends to sell or otherwise dispose of the
Property in a transaction in which taxable gain is recognized during a period of
five years after the expiration of the Tax Protection Period, the Partnership
shall use its diligent best efforts to effect such sale pursuant to a tax
deferred exchange transaction entered into pursuant to Section 1031 of the Code
pursuant to which no taxable gain is recognized by any Owner. In the event the
Partnership enters into any such tax deferred exchange transaction during the
Tax Protection Period, the provisions of this Section 12 shall apply to the
property received by the Partnership in such transaction for the remainder of
the Tax Protection Period. Notwithstanding the foregoing, the Partnership may
dispose of personal property and fixtures in the ordinary course of business or
in connection with any rehabilitation or remodeling of the Premises.


                                      -24-

<PAGE>

                  B. Unless otherwise agreed to by all of the Owners who receive
OP Units pursuant to this Agreement (such Owners for the purpose of this Section
12B only being herein called "Investors"), the Property Debt (as hereinafter
defined) shall, on the last day of each calendar year during the Tax Protection
Period, equal or exceed the Required Minimum Amount (as hereinafter defined).
All Property Debt shall be allocated among the partners in Purchaser in
accordance with Section 752 of the Code. As used herein, "PROPERTY DEBT" shall
mean, as to each Investor, the aggregate amount of indebtedness guaranteed by
such Investor pursuant to any Debt Guaranties (as hereinafter defined). If, at
any time during the Tax Protection Period, any Investors agree to execute
guaranties and/or other instruments (each, a "DEBT GUARANTY" and together with
any other outstanding Replacement Debt Guaranty, the "DEBT GUARANTIES") directly
guarantying an amount of indebtedness (which may be recourse or nonrecourse and
may be owing to Purchaser or other entities related thereto), in such form as
may be reasonably satisfactory to such Investor, Purchaser and AREIC, by which
such Investors agree to bear the economic risk of loss for an amount of
indebtedness, Purchaser agrees to deliver such Debt Guaranties (upon receipt
thereof from Investors) to the holder of such indebtedness and use reasonable
efforts to cause the holder to acknowledge such Debt Guaranties prior to the
close of the taxable year in which the Debt Guaranties are presented to
Purchaser. As used herein, "REQUIRED MINIMUM AMOUNT" means, as to each Investor,
the amount set forth on Exhibit F attached hereto. Anything to the contrary
notwithstanding, any Investor, upon written notice to the Assignee, may reduce
the Required Minimum Amount as to such Investor to the amount set forth in such
notice. Any such reduction shall be effective as of the first day of the
calendar month following the month in which such notice was given in accordance
with the terms of this Agreement.

                  C. Notwithstanding anything to the contrary contained herein
or in any document executed in connection herewith, no representations or
warranties are made with respect to the ability of the Owners to maintain their
respective tax bases in the Partnership or the Property, or to avoid the
recognition of gain and the incurrence of tax liability, in connection with the
structure or completion of any of the transactions contemplated hereby, and
Assignee shall have no liability or obligations in connection with any such
occurrences. In amplification of, and not in limitation to, the foregoing, each
Owner hereby acknowledges and agrees that (i) it has sufficient knowledge and
experience in financial, tax and business matters to enable it to evaluate the
merits and risks of investment in the OP Units, and, as to each Investor, such
Investor has the ability to bear the economic risk of acquiring the OP Units;
(ii) the transactions contemplated by this Agreement involve complex tax
consequences for such Owner, and such Owner is relying solely on the advice of
its own tax advisors in evaluating such consequences; (iii) neither Assignee nor
AREIC has made (or shall be deemed to have made) any representations or
warranties as to the tax consequences of such transaction to any Owner; (iv)
references in this Agreement to the intended tax effect of the acquisition of
the Partnership Interests and the other matters described herein shall not be
deemed to imply any representation


                                      -25-

<PAGE>

by Assignee as to a particular tax effect that may be obtained by the
Partnership or any Owner; and (v) such Owner remains solely responsible for all
tax matters relating to such Owner.

                  D. In order to account for the book-tax disparity with respect
to the assets contributed (or deemed contributed) to Assignee by Owners,
Assignee will elect to use the "traditional method" in accordance with Treasury
Regulation Section 1.704-3(b) and shall not use the traditional method with
curative allocations or the remedial method. Assignee shall also cause the
Partnership to elect to use the traditional method in accounting for the
book-tax disparity with respect to the assets treated as contributed to the
Partnership by Owner upon "termination" of the Partnership under Section
708(b)(1) of the Code.

         13.      INDEMNIFICATIONS

                  A. BY OWNERS. Each Owner, severally and not jointly and
severally, agrees to indemnify, defend and hold harmless GP Assignee and
Assignee from and against any and all losses, damages, claims, liabilities,
actions, suits, proceedings and costs and expenses of defense thereof, including
reasonable attorneys' fees, suffered or incurred by reason of or arising out of
the breach of such Owner's obligations, representations, warranties and
covenants contained in this Agreement. The liability of each Owner pursuant to
the provisions of this Section 13.A shall be limited, as to each demand, loss,
damage, claim or liability, to the portion thereof which is derived by
multiplying the amount of such item times the percentage interest of such Owner
designated on Exhibit A hereto under the column "Total Partnership Interest".
This indemnity shall survive the Closing and delivery of the Initial Interest
Assignments and shall not be merged therein; PROVIDED, HOWEVER, that each
Owner's liability shall not extend to those liabilities typically assumed by an
assignee in connection with the direct acquisition of a property (as opposed to
the acquisition of partnership interests in a partnership that retains ownership
of a property) nor to liabilities resulting from the physical condition of the
Property (by reason of the fact that Assignee is concluding this transaction
with the Property being in its "as is" "where as" condition as of the Closing
Date and in the context of the disclaimers set forth in Section 14.D below); and
PROVIDED FURTHER that Owners shall have no liability except to the extent the
loss suffered by GP Assignee and Assignee as a result of such claims exceeds
$10,000 in any one instance or $25,000 in the aggregate.

                  B. BY ASSIGNEE. Assignee agrees to indemnify, defend and hold
harmless Owners from and against all losses, damages, claims, liabilities,
actions, suits, proceedings and expenses of defense thereof, including
reasonable attorneys' fees, suffered or incurred by Owners by reason of or
arising out of the breach of Assignee's or AREIC's obligations, representations,
warranties and covenants contained in this Agreement; provided that Assignee
shall have no liability except to the extent the loss suffered by Owners as a
result of such claims exceeds $10,000 in any one instance or $25,000 in the
aggregate.


                                      -26-

<PAGE>

                  C. GENERALLY. Each indemnification under this Agreement shall
be subject to the following provisions: The indemnitee shall notify indemnitor
of any such claim against indemnitee within a reasonable time after it has
written notice of such claim, but failure to notify indemnitor shall in no case
prejudice the rights of indemnitee under this Agreement unless indemnitor shall
be prejudiced by such failure and then only to the extent of such prejudice.
Should indemnitor fail to discharge or undertake to defend indemnitee against
such liability within fifteen (15) business days after the indemnitee gives the
indemnitor written notice of the same, then indemnitee may settle such
liability, and indemnitor's liability to indemnitee shall be conclusively
established by such settlement, the amount of such liability to include both the
settlement consideration and the reasonable costs and expenses, including
attorneys' fees, incurred by indemnitee in effecting such settlement.

         14.      MISCELLANEOUS

                  A. Between the date of this Agreement and Closing Date,
Assignee and its agents or representatives shall have the right to enter upon
the Property for the purpose of examining, inspecting and testing the Property,
all subject to the terms and provisions of the Lease.

                  B. Neither this Agreement nor any interest hereunder shall be
assigned or transferred by the Owners. Assignee may assign or otherwise transfer
its interest under this Agreement to an affiliate of Assignee. Except as
provided in the preceding sentence, neither this Agreement nor any interest
hereunder shall be assigned or transferred by Assignee. Subject to the
foregoing, this Agreement shall inure to the benefit of and shall be binding
upon Owners and Assignee and their respective successors and assigns.

                  C. This Agreement constitutes the entire agreement between
Owner and Assignee with respect to the Partnership Interests, the Lease and the
Property and shall not be modified or amended except in a written document
signed by Owners and Assignee. Any prior agreement or understanding between
Owners and Assignee concerning the Partnership Interests, the Lease or the
Property is hereby rendered null and void.

                  D. Assignee acknowledges that (i) it and its representatives
have inspected the Property and the Lease and are familiar with the conditions
and terms thereof, and (ii) at Closing, the Initial Partnership Interests will
have been acquired by GP Assignee and Assignee with the Property and the Lease
in an "as is" and "where is" condition, and not in reliance on any agreement,
understanding, condition, warranty or representation made by Owners or any agent

                             KEYSTONE PROPERTY TRUST
                    200 FOUR FALLS CORPORATE CENTER, STE. 208

Keystone Property Trust Acquires 407,100 sf Bulk Warehouse For $16
Million in Central PA

   Increases Eastern/Central Industrial Ownership to 4.6 msf, Strengthening
   Keystone's Leadership Position in the Northeast Distribution Corridor

   WEST CONSHOHOCKEN, Pa., Dec. 15 /PRNewswire/ -- Keystone Property Trust
   (Amex: KTR) ("Keystone") announced today that it had acquired a 407,100 sf
   bulk distribution warehouse in Carlisle, PA for approximately $16 million
   from 21 Roadway Limited Partnership. The facility was built in 1988 and is
   100% leased for ten years to Dana Corporation, one of the world's largest
   independent suppliers to vehicle and engine manufacturers.

   21 Roadway Limited Partnership ("21 Roadway") is a private investment
   partnership controlled by Jeffrey E. Kelter, Keystone's President and Chief
   Executive Officer and certain other employees of the Company. Keystone has
   leased and managed the building since its purchase in January 1997. The terms
   of the acquisition were approved by a special subcommittee of Keystone
   Property Trust's Board of Directors formed specifically to review this
   related-party transaction. The purchase was funded with approximately $1.4
   million in Keystone Operating Units valued at $15.26 per unit (the average
   closing price for the 20 days preceding closing), $2.5 million in cash and
   the balance in mortgage financing. 21 Roadway used the cash to pay off
   existing encumbrances, with all partners taking OP units for their interest.

   Located at the intersection of Interstates 81 and 76, the 407,100 sf
   distribution facility has 35' clear ceiling heights, extensive frontage on
   the PA Turnpike, on-site parking for 250 trucks and rail service capability.
   Commenting on the acquisition, David McBride, Chairman of the Company,
   stated, "This property strengthens our distribution platform in the Northeast
   Distribution Corridor and further establishes our position as a leading
   provider of bulk warehouse space in Pennsylvania. It increases our ownership
   in Eastern/Central Pennsylvania, one of our core markets, to 4.6 million
   square feet. Furthermore, the facility has substantial development upside
   with an eight acre pad site that is fully entitled for 150,000 sf of
   expansion space, which we intend to begin developing in the second quarter of
   2000."

   Keystone Property Trust, with headquarters in West Conshohocken,
   Pennsylvania, is a fully-integrated, self-administered and self-managed real
   estate investment trust which currently owns 133 industrial and office
   properties aggregating 18.7 million square feet in the Eastern United States.
   Keystone's industrial portfolio, pro forma for all acquisitions under
   contract, will contain approximately 19.0 msf "big box" distribution assets,
   with 16.2 msf in-place assets located in the Northeast Distribution Corridor,
   which encompasses New Jersey, Central Pennsylvania, Central Ohio, New York
   State and Indianapolis. For more information, contact Timothy A. Peterson at
