Under all other circumstances, wherever under this Agreement and the Other Agreements the Deposit is to be returned to Purchaser, $150,000 out of the Deposit shall be paid to Seller, to be retained by Seller as fully earned. 3. Review of the Property. 3.1 From and after the "Effective Date" (as defined in Paragraph 9.23), Seller agrees to provide Purchaser and its agents or consultants with access to the Property to inspect each and every part thereof to determine its present condition and to conduct such physical and environmental studies (including a mechanical and roof study and Phase I environmental assessment) as it deems appropriate. 3.2 Within three (3) business days after the Effective Date Seller will make available to Purchaser for inspection and copying, all to the extent in the possession of Seller or its managing agent, a copy of each existing Lease and equipment lease, service contract and maintenance or other contract pertaining to the operations of the Property that will survive Closing, a copy of each real estate tax bills for 1994-1996, both inclusive, and unaudited financial statements for the Property for the years 1994-1996, both inclusive. 3.3 Within three (3) business days after the Effective Date Seller will make available to Purchaser for inspection and copying at the office of Seller's managing agent, all to the extent in the possession of Seller or its managing agent: 3.3.1 a copy of each environmental reports relating to the Property prepared by third party consultants since January 1, 1995. 3.3.2 a copy of each current franchises, business or other licenses, bonds, permits, certificates, authorizations and other evidences of consent, approval, authorization or permission relating to or affecting the Project of or from any person, including any governmental authority, held by Seller, including any pending applications. 3.3.3 a copy of each material third party warranties and guaranties, if any, which are in effect with respect to the Property. 3.4 Purchaser has until 5:00 p.m. CST on February 2, 1998 (the "Review Period"), to determine in its sole discretion whether all matters relating to the Property (except title and survey, which are governed by Paragraph 4), are acceptable, and to obtain the approval of the transaction contemplated herein by Seller's Board of Directors. If Purchaser concludes that any matter relating to the Property is not acceptable or that its Board has disapproved the 2 transaction, Purchaser will so notify Seller (the "Termination Notice") prior to the expiration of the Review Period (which notice shall contain a copy of Purchaser's roof/structural report and other reports or studies, other than environmental reports, obtained in connection with Purchaser's due diligence). Upon timely delivery of the Termination Notice, this Agreement will terminate without liability on the part of Seller or Purchaser, other than Purchaser's indemnity contained in Paragraph 9.15 hereof and the obligation to deliver to Seller a copy of any environmental report obtained by Purchaser if requested by Seller within ten (10) days after receipt of the Termination Notice. In the event that Purchaser does not timely so notify Seller, Purchaser will be deemed to have concluded that all matters relating to the Property are acceptable and to have elected to proceed with the transaction upon the terms and conditions contained in this Agreement (including the obligation to increase the amount of the Deposit by an additional $500,000) without regard to this Paragraph 3.4. 3.4.1 If this Agreement is terminated pursuant to Paragraph 3.4, the Deposit, less $150,000, will be returned to Purchaser as provided in the Escrow Instructions. This $150,000 shall be paid to Seller, unless Purchaser's termination resulted from (i) Seller's default, (ii) a material deviation from the economics of the Property as presented in Seller's offering memorandum (it being understood and agreed that Seller makes no warranty or representation as to said offering memorandum), or (iii) any material structural or environmental defect in the Property not known or disclosed to Purchaser before December 22, 1997. 3.5 Purchaser agrees that any information obtained by Purchaser or its authorized agents in the conduct of its due diligence will be treated as confidential pursuant to Paragraph 9.17. 4. Title and Survey. Purchaser has ordered, at its expense (and upon receipt, Purchaser shall promptly deliver copies to Seller): (i) a commitment for a 1992 form ALTA Owner's title insurance policy with respect to the Property from Commonwealth Land Title Insurance Company (the "Title Insurer") in the amount of the Purchase Price, and (ii) copies of all documents relating to title exceptions referred to therein. Seller has already ordered, and Purchaser has received, at Purchaser's sole expense, a plat of survey of the Property made in accordance with Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys (1992) pursuant to the accuracy standards of an Urban Survey. On or before January 30, 1998, Purchaser agrees to notify Seller of any objection Purchaser may have to any exceptions reported in the commitment or any matter shown on the plat of survey (the "Unacceptable Exceptions"). Seller will be responsible for satisfaction of the Title Insurer's Schedule B-1 seller requirements. All other exceptions and survey matters will be deemed acceptable to Purchaser. If Purchaser fails to give such notice to Seller, the survey and all of the exceptions in the title commitment will be deemed acceptable to Purchaser. Seller will have ten (10) days after receipt of Purchaser's notice within which to notify Purchaser whether Seller elects to either (a) eliminate or induce the Title Insurer to insure over (subject to Purchaser's consent, not to be unreasonably withheld) the Unacceptable Exceptions or (b) terminate this Agreement. If Seller agrees to eliminate or induce to the Title Insurer to insure over (with Purchaser's consent) the 3 Unacceptable Exceptions, Seller will be obligated to do so at its cost on or prior to Closing. If Seller elects to terminate this Agreement, neither party will have any further rights or obligations hereunder, except as provided in Paragraph 9.15. If Seller fails to give any timely notice, Seller will be deemed to have elected to terminate this Agreement. If any other recorded exception to title is discovered after the commitment is delivered to Purchaser, and Purchaser does not elect to waive such exception upon the first to occur of (a) the Closing or (b) seven (7) days after being notified of such exception and to proceed with the consummation of the Closing, Seller will have fifteen (15) days after the expiration of said seven (7) day period (and Closing will be delayed if necessary, so that it occurs not earlier than twenty-two (22) days after Purchaser is notified of such exception) after notifying Purchaser of such discovery in which to use commercially reasonable efforts to eliminate or to induce the Title Insurer to insure over (subject to Purchaser's approval, not to be unreasonably withheld) such exception, and if such exception is not eliminated or insured over as aforesaid within said 15-day period, Purchaser may terminate this Agreement, in which event the Deposit will be returned to Purchaser and neither party will have any further rights or obligations hereunder except as provided in Paragraph 9.15, or close the sale subject to such exception. Seller agrees that it will pay off at Closing (and not induce the Title Insurer to insure over) title exceptions representing monetary liens of a definite or ascertainable amount voluntarily granted by Seller. In using commercially reasonable efforts to eliminate or to induce the Title Insurer to insure over Unacceptable Exceptions, Seller will not be required to litigate or to expend more than $10,000 in the aggregate. Ad valorem real estate taxes not yet due and payable and all title and survey matters which are not Unacceptable Exceptions are hereinafter referred to as Acceptable Exceptions. 5.

Each of the representations and warranties of Seller contained in Paragraph 5.1: (i) is made as of the date of this Agreement; (ii) will be deemed to be remade by Seller, and to be true in all material respects, as of Closing, subject to other matters expressly permitted in this Agreement or otherwise specifically approved in writing by Purchaser; and (iii) will survive for a period of one (1) year after the Closing Date, as defined in Paragraph 8.1. Any claim that Purchaser may have at any time against Seller for a breach of any such representation or warranty, whether known or unknown, which is not asserted by notice from Purchaser to Seller within such six (6) month period will not be valid or effective, and Seller will have no liability with respect thereto. Nor will Seller have any liability to Purchaser for a breach of any representation or warranty unless the valid claims for all such breaches collectively aggregate more than One Hundred Thousand Dollars ($100,000.00), in which event the full amount of such valid claims shall be actionable, subject to the limitation in Section 9.10. The continued accuracy in all material respects of the aforesaid representations and warranties is a condition precedent to Purchaser's obligation to close. If any of said representations and warranties is not correct in all material respects at the time the same is made or as of Closing, and Seller had no knowledge of such inaccuracy when the representation or warranty was made, or when remade at Closing, or if such warranty or representation becomes inaccurate on or prior to Closing other than by reason of Seller's default hereunder, Purchaser may, upon being notified of such occurrence on or prior to Closing either (a) terminate this Agreement without liability on the part of Seller or Purchaser, other than Purchaser's indemnity contained in Paragraph 9.15 and the Deposit will be returned to Purchaser, or (b) waive such matter and proceed to Closing, by notice to Seller given within ten (10) days after Purchaser is notified of such occurrence, but in no event later than Closing. If Purchaser fails to give any notice within the required time period, Purchaser will be deemed to have elected to waive such matter and to proceed to Closing. If any of said representations and warranties are not correct in all material respects at the time the same is made or as of Closing, and Seller had knowledge of such inaccuracy when the representation or warranty was made, or, by its default hereunder caused the representation or warranty to be inaccurate when remade at Closing, Purchaser may either (x) terminate this Agreement subject to its obligations under Paragraph 9.15, receive a return of the Deposit and recover from Seller all of Purchaser's actual, reasonable out-of-pocket costs incurred in connection with its review of 7 the Property or (y) waive the breach and its rights under clause (x) and proceed to Closing, by notice to Seller given within ten (10) days after Purchaser is notified of such occurrence, but in no event later than Closing. If Purchaser fails to give any notice within the required time period, Purchaser will be deemed to have elected to waive such matter and to proceed to Closing. 5.4 Condition of Property. Except as expressly set forth in this Agreement, Seller has not made and does not hereby make any representations, warranties or other statements as to the condition of the Property and Purchaser acknowledges that at Closing it is purchasing the Property on an "AS IS, WHERE IS" basis and without relying on any representations and warranties of any kind whatsoever, express or implied, from Seller, its agents or brokers as to any matters concerning the Property. Except as expressly set forth in this Agreement, no representations or warranties have been made or are made and no responsibility has been or is assumed by Seller or by any partner, officer, person, firm, agent or representative acting or purporting to act on behalf of Seller as to the condition or repair of the Property or the value, expense of operation, or income potential thereof or as to any other fact or condition which has or might affect the Property or the condition, repair, value, expense of operation or income potential of the Property or any portion thereof. The parties agree that all understandings and agreements heretofore made between them or their respective agents or representatives are merged in this Agreement and the Schedules and Exhibits hereto annexed, which alone fully and completely express their agreement, and that this Agreement has been entered into after full investigation, or with the parties satisfied with the opportunity afforded for investigation, neither party relying upon any statement or representation by the other unless such statement or representation is specifically embodied in this Agreement or the Exhibits annexed hereto. Purchaser acknowledges that Seller has requested Purchaser to inspect fully the Property and investigate all matters relevant thereto and, with respect to the condition of the Property, to rely solely upon the results of Purchaser's own inspections or other information obtained or otherwise available to Purchaser, rather than any information that may have been provided by Seller to Purchaser. 6. Closing Conditions. Purchaser's obligation to proceed to Closing is conditioned upon Seller's performance of the following obligations and satisfaction of the following conditions, in addition to all of its other obligations and conditions contained in this Agreement, provided that Purchaser may in its sole discretion elect to waive failure by Seller to perform any particular obligation. 6.1 Title Insurance. The Title Insurer is prepared to issue a policy of title insurance insuring Purchaser's interest in the Property being conveyed, subject only to Acceptable Exceptions. 6.2 Estoppel Letters. Seller has delivered to Purchaser not later than the date of Closing, estoppel letters substantially in the form of Schedule 6.2 ("Required Estoppel Form") or in form otherwise reasonably acceptable to Purchaser, prepared by Seller and 8 addressed to Purchaser, from tenants occupying in the aggregate at least 75% of the Property, measured by square footage. All estoppel letters must be dated not more than forty-five (45) days prior to the date of Closing. An estoppel letter form, even though not in the Required Estoppel Form, will be deemed reasonably acceptable to Purchaser if said letter contains the following information: confirming rent, security deposit, square footage and termination date; that no rent has been paid more than one month in advance; that the lease is in full force and effect and that a true and correct copy of the lease with all amendments and modifications is attached; and that all work to be performed by Landlord has been performed and that the tenant has no knowledge of any Landlord default. 6.2.1 If Seller is unable to obtain the requisite estoppel letters as described above, Seller may (but is not required to) substitute for any unsigned estoppel letter from a tenant other than a Major Tenant an estoppel letter in the Required Estoppel Form, which may be completed, executed and delivered by Seller and warranted and represented by Seller, provided that such substituted estoppel letters will not collectively represent in excess of 10% of all of the tenants, measured by square footage. Seller's representations and warranties in the certificates will survive the Closing subject to the limitations of Paragraph 5.3. In the event that, following the Closing Date, Seller or Purchaser obtains an estoppel letter complying with the requirements of Paragraph 6.2 with respect to any lease for which Seller delivered a substituted estoppel letter, Seller will deliver such estoppel letter to Purchaser and, upon such delivery, Seller will be automatically released from any liability or obligation under the substituted estoppel letter previously delivered by Seller with respect to such lease. Purchaser may (but shall not be required to) accept a substituted estoppel letter as to a Major Tenant as well. 6.2.2 If Seller is unable to obtain and deliver sufficient tenant estoppel certificates as required under Paragraph 6.2, or if the letters received under Paragraph 6.2 or substituted estoppels permitted under Paragraph 6.2.1 contain information or omissions unacceptable to Purchaser in its reasonable discretion, then Seller will not be in default by reason thereof, but Purchaser may, by notice given to Seller before the Closing, elect (i) to waive said conditions and proceed with the Closing or (ii) to terminate this Agreement, and receive a refund of the Deposit. If Purchaser elects to terminate this Agreement, neither party will have any further rights or obligations hereunder except as provided in Paragraph 9.15. 6.3 Representations and Warranties. All of Seller's representations and warranties made pursuant to Paragraph 5.1 remain true and correct in all material respects. 6.4 Seller Performance. Seller has delivered all of the documents and other items required pursuant to Paragraph 8.6 and has performed all other covenants, undertakings and obligations required by this Agreement, to be performed or complied with by Seller at or prior to Closing. 7. Other Agreements. The obligations of Purchaser and Seller to close hereunder shall also be conditioned upon the simultaneous closing of (a) the purchase by Purchaser or an 9 affiliate of Purchaser, of twelve industrial and office buildings and a parcel of vacant land in King of Prussia Business Park, King of Prussia, Pennsylvania, pursuant to that certain Agreement of Purchase and Sale of even date herewith ("KOP Agreement") between Purchaser, as purchaser, and RREEF USA Fund-I ("KOP Owner"), as seller, and (b) the purchase by Purchaser or an affiliate of Purchaser, of the industrial building commonly known as 180 Wheeler Court, Bucks County, Pennsylvania, pursuant to that certain Agreement of Purchase and Sale of even date herewith (the "Wheeler Court Agreement"; the KOP Agreement and the Wheeler Court Agreement collectively the "Other Agreements") between Purchaser, as purchaser, and RREEF MidAmerica East-V Six, Inc. ("Wheeler Court Owner"; the KOP Owner and the Wheeler Court Owner are collectively referred to as the "Other Owners"), as seller. This condition may be waived by the parties. Without limiting the generality of the foregoing, if Purchaser terminates this Agreement pursuant to Section 3 or Section 4, the Other Owners shall have the right to terminate the Other Agreements as well; or, if Purchaser terminates one or more of the Other Agreements pursuant to Section 3 or Section 4 of the Other Agreements, Seller shall have the right to terminate this Agreement as well. A default by Purchaser under one or more of the Other Agreements shall be deemed a Purchaser default hereunder, and a default by an Other Owner under one or more of the Other Agreements shall be deemed a Seller default hereunder. 8. Closing. 8.1 Closing of Sale. The purchase and sale contemplated herein shall close (herein referred to as the "Closing") at the office of the Title Insurer, or as otherwise mutually agreed, on a date selected by Seller, which date (the "Closing Date") shall not be earlier than the date which is fifteen (15) days after the expiration of the Review Period nor more than thirty (30) days after expiration of the Review Period, time being of the essence. At Closing, Seller will deliver to Purchaser a Special Warranty Deed ("Deed") in the form of Schedule 8.6.1 and other closing documents required hereunder and Purchaser will cause payment of the Purchase Price to be made to Seller by wire transfer. The sale (payment of the Purchase Price and delivery of the Deed) may, at Purchaser's option to be exercised by notice to Seller at least five (5) days prior to the Closing Date, be closed through escrow with the Title Insurer in accordance with the general provisions of the usual form of escrow agreement used in similar transactions by such Title Insurer with special provisions inserted (i) as may be required to conform with this Agreement and (ii) to close on a so-called "New York Style" basis. 8.2 Prorations; Adjustments. The parties will prorate taxes, rental, and other income, and operating or other expenses of the Property as of 12:01 a.m. on the date after Closing (i.e., Seller is entitled to the income and responsible for the expenses of the day of Closing). All income will be prorated on the basis of income actually received by Seller, as opposed to income which is due or for which Seller has rendered invoices but which has not been paid (i.e., Seller will not be entitled to any credit for receivables, and there will be no proration as to such receivables). Any taxes or other expenses of the Property for any period prior to Closing which are payable by tenants of the Property subsequent to Closing (e.g., real estate taxes paid in arrears and not yet billed to tenants), will reduce the credit to Purchaser for such items (i.e., no 10 credit from Seller for pass-through items for which Purchaser will later collect from the tenants). To the extent that the taxes to be prorated are not known with certainty, such proration will be based upon the most recent tax bill or county estimate, to be re-prorated upon issuance of final bills. Seller also agrees to give Purchaser a credit against the Purchase Price for all cash security deposits required to be held pursuant to the Leases (less portions thereof applied by Seller to tenant defaults and not subsequently restored by the tenant in question) and all interest due thereon and shall assign to Purchaser any other tenant deposits held by Seller. Purchaser will pay amounts subsequently received by it from tenants constituting base rent, capital reimbursements or other income due from tenants and attributable to Seller's period of ownership, but not collected as of the date of Closing, to Seller promptly upon receipt; provided that amounts received from tenants by Purchaser will be first applied to current charges, and the balance will be applied to payments due to Seller. Notwithstanding the foregoing, Seller shall expressly reserve the right to seek to collect, directly from the tenants after Closing and with Purchaser's cooperation, any delinquencies and other amounts attributable to Seller's period of ownership, but not collected as of the date of Closing. To the extent Seller has received amounts from tenants for real estate taxes and 1997 and 1998 operating expenses in excess of amounts paid by Seller with respect to such expenses, Seller will credit such excess to Purchaser at Closing, and Seller will provide adequate backup information in connection with such credit. On or after the Closing, Seller will have no further obligations with respect to any Leases or other agreements affecting the Property, including, without limitation, tenant improvement work, leasing commissions and free rent. 8.2.1 Seller and Purchaser hereby agree to use their reasonable efforts to calculate prorations (including real estate tax prorations) so as to permit settlement thereof on the Closing Date, provided, however, that if any of such prorations cannot be calculated accurately on the Closing Date, then the same will be calculated as soon as reasonably practicable after the Closing Date, but in no event later than the later to occur of (i) thirty (30) days after Seller receives its final cost certification for the year in which Closing occurs, or (ii) March 31 of the year following the year in which Closing occurs, and either party owing the other party a sum of money based on such subsequent proration(s) shall promptly pay said sum to the other party, together with interest thereon at the rate of two percent (2%) per annum over the "prime rate" (as announced from time to time in the Wall Street Journal) from the Closing Date to the date of payment if payment is not made within thirty (30) days after delivery of a bill therefor together with reasonable back-up documentation. This obligation of the parties will survive Closing. 8.3 Proration of Service Charges. To the extent Seller, as opposed to tenants, is responsible for payment of utility charges, Seller will attempt to have utility meters read as of the Closing Date. To the extent that this is not possible and to the extent that any other obligation for continuing services is incurred, and statements are rendered for such services covering periods both before and after the Closing Date, the amount will be adjusted between the parties as of the Closing Date on a per-diem basis. Seller will forward any such statements which it receives to Purchaser and Purchaser will pay the same. Seller will remit to Purchaser its proportionate share immediately upon demand. 11 8.4 Closing Costs. Purchaser agrees to pay (i) the Title Insurer's escrow and/or closing fees (including any payment to the closing officer of the Title Insurer as may be the local custom at the Closing), (ii) the cost of the title commitment and basic policy and endorsements, if any, required to meet Seller's obligations hereunder and the cost of any endorsements to the title policy required by Purchaser, including extended coverage, (iii) all recording fees and taxes with respect to the Deed, (iv) all costs of Purchaser's physical inspections of the Property (environmental, engineering) and other due diligence activities; (v) all costs of survey, including fees and charges of Gannett Fleming Associates (originally engaged by Seller); (vi) cancellation charges, if applicable, to Coventry Abstract (originally engaged by Seller); and (vii) one-half (1/2) of applicable transfer taxes. Seller agrees to pay (i) all recording fees with respect to clearing Seller's title, and (ii) one-half (1/2) of applicable transfer taxes. Except as otherwise provided in Paragraph 9.9, each party is responsible for its own attorneys' and other professional fees. All other closing costs shall be allocated in accordance with the prevailing local custom. 8.5 Possession. Subject to the rights of tenants pursuant to Leases delivered to Purchaser, Seller will deliver possession of the Property and of any conveyed personal property to the Purchaser on the date of Closing and Seller will thereupon deliver to Purchaser the originals of all Leases, all correspondence with tenants, tenant/lease files, operating statements, plans and specifications, supplies and advertising materials, booklets, keys, and other items used in connection with operation of the Property. 8.6 Seller's Closing Documents. As part of the Closing, Seller will deliver to Purchaser: 8.6.1 the Deed, in the form of Schedule 8.6.1 8.6.2 an affidavit in customary form that Seller is not a foreign person within the meaning of Section 1445(e) of the Internal Revenue Code of 1986, in the form of Schedule 8.6.2; 8.6.3 such affidavits as are customarily required by Title Insurer in connection with issuance of the owner's basic title insurance policy, including a mechanics' lien and judgment affidavit; 8.6.4 an assignment of the Leases in the form of Schedule 8.6.4 ("Lease Assignment"); 8.6.5 an assignment of contracts and warranties in the form of Schedule 8.6.5 ("Contracts Assignment"), assigning to Purchaser all contracts listed on Schedule 5.1.5, other than those designated by Purchaser for termination by notice to Seller not less than thirty (30) days prior to Closing; 12 8.6.6 an assignment of intangibles in the form of Schedule 8.6.6 ("Intangibles Assignment"); 8.6.7 letters, in form to be supplied by Purchaser, to the tenants at the Property, instructing the tenants to pay rent to Purchaser and to recognize Purchaser as landlord under their Leases; 8.6.8 a bill of sale conveying all personal property of Seller, if any, located at the Property and used in connection with the maintenance or operation thereof (specifically excluding furniture, fixtures and equipment owned by RREEF Management Company and located in the RREEF Management Company office), in the form of Schedule 8.6.8; 8.6.9 a rent roll, certified by Seller as being true and correct, to Seller's knowledge, as of the Closing Date, in the form previously delivered to Purchaser; 8.6.10 a "bring down certificate" stating that Seller's representations and warranties are true and correct as of the Closing Date, in the form of Schedule 8.6.10; 8.6.11 estoppel certificates as required by Paragraph 6.2 herein; and 8.6.12 all other documents, instruments or writings which may be reasonably required to consummate the transactions contemplated herein. 8.7 Purchaser's Closing Documents. As part of the Closing, Purchaser will deliver to Seller: 8.7.1 good federal funds in an amount equal to the Purchase Price, less the Deposit and interest thereon and plus or minus prorations as provided herein and plus funds sufficient to pay Purchaser's closing costs hereunder; 8.7.2 such affidavits as are customarily required by Title Insurer in connection with issuance of the owner's title insurance policy; 8.7.3 executed counterpart of the Lease Assignment; 8.7.4 executed counterpart of the Contracts Assignment; 8.7.5 executed counterpart of the Intangibles Assignment; 8.7.6 all other documents, instruments or writings which may be reasonably required to consummate the transactions contemplated herein. 13 8.8 Joint Deliveries. At the Closing, Seller and Purchaser will execute and deliver to each other the following documents in proper form: 8.8.1 Closing Statement; 8.8.2 City, county and state transfer tax declarations or similar instruments; and 8.8.3 All other documents, instruments or writings which may be reasonably required to consummate the transactions contemplated herein. 9. Miscellaneous. 9.1 Modifications. This Agreement can be amended only in writing signed by both of the parties. 9.2 Casualty and Condemnation. Seller agrees to keep its customary replacement cost insurance covering the Property in effect until the Closing. If between the Effective Date and the Closing the improvements on the Property are destroyed or damaged to the extent that repairs cost in excess of $250,000 in the estimate of an architect or contractor selected by Seller and reasonably acceptable to Purchaser, or if condemnation proceedings are commenced against the Property, Purchaser may (i) terminate this Agreement or (ii) elect to accept the Property in its then condition, in which event Seller will pay or assign to Purchase at Closing all proceeds of insurance (plus the applicable deductible) or condemnation awards payable to Seller by reason of such damage or condemnation. In the event Purchaser makes neither election by the earlier of (a) Closing or (b) ten (10) days after being advised of such casualty or condemnation, Purchaser will be deemed to have elected to accept the Property in its then condition. In the event of any other damage to the Property, Seller may either repair the damage or give Purchaser a reduction in the Purchase Price equal to the cost of repairing such damage, as certified by an architect or contractor selected by Seller and reasonably acceptable to Purchaser. In the event of any damage where Purchaser does not have the right to terminate and Seller elects to repair such damage, the Closing Date shall be delayed for the number of days required to repair the damage, which Seller agrees to do in accordance with all Laws and in a good and workmanlike manner. 9.3 Time of Essence. Time (including, without limitation, the date specified as the Closing Date) is of the essence of this Agreement. 9.4 Notices. All notices required or permitted hereunder must be in writing and shall be served on the parties at the following address: If to Purchaser: Brandywine Realty Trust 14 Newtown Square Corporate Campus 16 Campus Blvd. Suite 150 Newtown Square, PA 19073 Attn: Gerard H.

Neither party may assign this Agreement without the prior written consent of the other, and any such prohibited assignment shall be void; provided that Purchaser may assign this Agreement without Seller's consent to an Affiliate; provided that the assignee is not a party-in-interest as described in Paragraph 9.14. Subject to the foregoing, this Agreement is binding upon and inure to the benefit of the respective legal representatives, successors, assigns, heirs, and devisees of the parties. For the purposes of this Paragraph, the term "Affiliate" means (a) an entity that directly or indirectly controls, is controlled by or is under common control with the Purchaser or (b) an entity at least a majority of whose economic interest is owned by Purchaser; and the term "control" means the power to direct the management of such entity through voting rights, ownership or contractual obligations. 9.6 Governing Law. The performance and interpretation of this Agreement is controlled by the law of the Commonwealth of Pennsylvania. 9.7 Continuation Until Closing; Leasing. 9.7.1 Between the Effective Date and the Closing, Seller agrees to keep and perform all of the obligations to be performed by landlord under any Leases and Laws. Seller agrees to operate the Property in the same manner as before the making of this Agreement, the same as though Seller were retaining the Property. Seller agrees not to convey the Property, nor to grant any liens or easements with respect thereto. 9.7.2 Seller shall not permit or consent to any new leases, amendments, extensions, renewals (other than pursuant to tenant renewal options, if any) or subleases without first submitting them to Purchaser for Purchaser's approval on an approval form in the form attached hereto as Schedule 9.7.2, which approval shall not be unreasonably withheld. Purchaser shall have three (3) business days to notify Seller of its approval of such leases, amendments, extensions, renewals or subleases, and in the event that Purchaser does not so notify Seller, the leases, amendments, extensions, renewals or subleases, as the case may be, shall be deemed approved. 9.7.3 With respect to any new lease or lease modification entered into by Seller after December 18, 1997 and approved by Purchaser, by the terms of which Seller obligates itself to perform or performs or pays or contracts for any tenant improvement work or additional landlord work required pursuant to such lease, or pays or contracts for any leasing commissions or grants any free rent period or other financial concessions, then such expenses and/or free rent or other concessions, and all other third-party costs incurred (including attorneys' fees) in connection with such lease, will be a credit to Seller at Closing to the extent Seller paid such amounts prior to Closing; otherwise Purchaser agrees to assume liability for the payment and performance of such obligations in accordance with the terms thereof. 9.8 Brokers. Seller and Purchaser each (i) represents and warrants to the other that it has not dealt with any broker or finder in connection with the transaction contemplated by 16 this Agreement other than the parties, if any, to be paid a commission as specified in Paragraph 9.11, and (ii) agrees to defend, indemnify and hold the other harmless from and against any losses, damages, costs, or expenses (including attorneys' fees) incurred by such other party due to a breach of the foregoing warranty by the indemnifying party. 9.9 Attorneys' Fees. Notwithstanding any limitation on remedies or amounts recoverable set forth elsewhere herein, if any action is brought by either party against the other party, the party in whose favor final judgment is entered will be entitled to recover court costs incurred and reasonable attorneys' fees at trial, upon appeal and on any petition for review. 9.10 Remedies for Non-Performance. Purchaser's remedies regarding breach of warranty or representation by Seller are governed by Paragraph 5.3. In the event of any other default by Seller hereunder, Purchaser may, as its sole and exclusive remedy, either (i) terminate this Agreement and seek damages, subject to performance of Purchaser's indemnities set forth in Paragraph 9.15, and receive back the Deposit or (ii) seek specific performance. If said sale is not consummated because of a default under this Agreement on the part of Purchaser, the Deposit will be paid to and retained by Seller as Seller's sole and exclusive remedy. Seller and Purchaser acknowledge that the Deposit is a reasonable forecast of just compensation for the harm that could be caused by Purchaser's default and that the harm suffered by Seller is difficult or impossible to accurately ascertain or predict. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, SELLER'S TOTAL LIABILITY FOR DAMAGES FOR BREACH OF THE COVENANTS, AGREEMENTS, WARRANTIES AND REPRESENTATIONS UNDER THIS AGREEMENT AND THE OTHER AGREEMENTS, COLLECTIVELY, SHALL NEVER EXCEED TWO MILLION DOLLARS ($2,000,000.00), AND IN NO EVENT SHALL SELLER BE LIABLE FOR SPECIAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES. 9.11 Brokers Commission. Seller agrees to pay the brokerage commission due The Flynn Company pursuant to a separate agreement. 9.12 Survival of Covenants. All covenants hereunder which, by their terms, are intended to survive Closing will survive Closing hereunder. 9.13 Seller's Investment Committee Approval. This condition has been satisfied. 9.14 ERISA. Purchaser represents and warrants to Seller that none of Purchaser's assets are "plan assets," (as that term is defined by 29 CFR Section 2510.3-101) because all plans that are subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended, and which have invested in Purchaser hold only "equity interests," (as that term is defined by 29 CFR Section 2510.3-101(b)(1)) that are "publicly-offered securities," (as that term is defined by 29 CFR Section 2510.3-101(b)(2)). Purchaser further represents and warrants to Seller that 17 it is not any one of the types of entities listed in 29 CFR Section 2510.3-101(h), the character of which would identify its assets as "plan assets." 9.15 Entry and Indemnity. In connection with any entry by Purchaser, or its agents, employees or contractors onto the Property, Purchaser shall give Seller reasonable advance notice of such entry and shall conduct such entry and any inspections in connection therewith so as to minimize, to the greatest extent possible, interference with Seller's business and the business of Seller's tenants and otherwise in a manner reasonably acceptable to Seller. Without limiting the foregoing, prior to any entry to perform any on-site testing, Purchaser shall give Seller notice thereof, including the identity of the company or persons who will perform such testing and the proposed scope of the testing. Seller shall approve or disapprove the scope and methodology of such proposed testing within three (3) business days after receipt of such notice, such approval to be within the sole and unfettered discretion of Seller; Seller's failure to notify Purchaser of its approval or disapproval shall be deemed to be Seller's disapproval thereof. If Purchaser or its agents, employees or contractors take any sample from the Property in connection with any such approved testing, upon Seller's request, Purchaser shall provide to Seller a portion of such sample being tested to allow Seller, if it so chooses, to perform its own testing. Seller or its representative may be present to observe any testing or other inspection performed on the Property. Upon Seller's request, Purchaser shall promptly deliver to Seller copies of any reports relating to any testing or other inspection of the Property performed by Purchaser or its agents, employees or contractors. Purchaser shall maintain, and shall assure that its contractors maintain, public liability and property damage insurance in amounts and in form and substance adequate to insure against all liability of Purchaser, its agents, employees or contractors, arising out of any entry or inspections of the Property pursuant to the provisions hereof, and Purchaser shall provide Seller with evidence of such insurance coverage upon request by Seller. Purchaser shall indemnify, defend and hold Seller harmless from and against any costs, damages, liabilities, losses, expenses, liens or claims (including, without limitation, reasonable attorney's fees) arising out of or relating to any entry on the Property by Purchaser, its agents, employees or contractors in the course of performing the inspections, testings or inquiries provided for in this Agreement, including without limitation damage to the Property or release of hazardous substances or materials onto the Property, excluding, however, any costs incurred by Seller in supervising Purchaser's testing. The foregoing indemnity shall survive beyond the Closing, or if the sale is not consummated, beyond the termination of this Agreement. 9.16 Release. Except to the extent of the representations and warranties of Seller expressly set forth in this Agreement, and except to the extent of a breach by Seller of applicable laws, but otherwise notwithstanding any other provision of this Agreement to the contrary, Purchaser, on behalf of itself and its successors and assigns, waives its right to recover from, and forever releases and discharges, Seller, Seller's affiliates, Seller's investment manager, the partners, trustees, shareholders, directors, officers, employees and agents of each of them, and their respective heirs, successors, personal representatives and assigns (collectively, the "Seller Related Parties"), from any and all demands, claims, legal or administrative proceedings, losses, liabilities, damages, penalties, fines, liens, judgments, costs or expenses whatsoever (including, 18 without limitation, attorneys' fees and costs), whether direct or indirect, known or unknown, foreseen or unforeseen, which may arise on account of or in any way be connected with the physical condition of the Property or any law or regulation applicable thereto, including, without limitation, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (42 U.S.C. Sections 9601 et seq.), the Resources Conservation and Recovery Act of 1976 (42 U.S.C. Section 6901 et seq.), the Clean Water Act (33 U.S.C. Section 466 et seq.), the Safe Drinking Water Act (14 U.S.C. Sections 1401-1450), the Hazardous Materials Transportation Act (49 U.S.C. Section 1801 et seq.), and the Toxic Substance Control Act (15 U.S.C. Sections 2601-2629) 9.17 Confidential Information. The parties acknowledge that the transaction described herein is of a confidential nature and shall not be disclosed except to consultants, investors, advisors, and affiliates, or as required by law. No party will make any public disclosure of the specific terms of this Agreement, except as required by law. Without limiting the generality of the foregoing, any press release or other public disclosure regarding this Agreement or the transactions contemplated herein, and the wording of same, must be approved in advance by both parties. In connection with the negotiation of this Agreement and the preparation for the consummation of the transactions contemplated hereby, each party acknowledges that it will have access to confidential information relating to the other party. Each party shall treat such information as confidential, preserve the confidentiality thereof, and not duplicate or use such information, except to advisors, consultants, investors and affiliates in connection with the transactions contemplated hereby. In the event of the termination of this Agreement for any reason whatsoever, Purchaser will return to Seller, at Seller's request, all documents, work papers, and other material (including all copies thereof) obtained from Seller in connection with the transactions contemplated hereby, and each party shall use its best efforts, including instructing its employees and others who have had access to such information, to keep confidential and not to use any such information. The provisions of this Paragraph 9.17 will survive the Closing or, if the purchase and sale is not consummated, any termination of this Agreement. 9.18 Calculation of Time Periods. Unless otherwise specified, in computing any period of time described herein, the day of the act or event, after which the designated period of time begins to run, is not to be included and the last day of the period so computed is to be included, unless such last day is a Saturday, Sunday or legal holiday, in which event the period shall run until the end of the next day which is neither a Saturday, Sunday, or legal holiday (i.e., a day on which federally chartered banks are not open for business in Chicago, Illinois).

This Agreement and such documents supersede all prior agreements and understandings among the parties with respect to the subject matter hereof 9.20 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement, or affecting the validity or enforceability of any of the terms or provisions of this Agreement. 9.21 Facsimile Signatures. Executed facsimile copies of this Agreement or any amendments hereto shall be binding upon the parties, and facsimile signatures appearing hereon or on any amendments hereto shall be deemed to be original signatures. 9.22 Further Assurances.

The date on which Seller delivers a fully executed copy of this Agreement to Purchaser, or delivers a copy by facsimile transmission followed by a manually signed copy as provided in the preceding sentence is referred to herein as the "Effective Date." 9.24 Seller Exculpation Clause. The obligations of Seller contained herein are intended to be binding only on the property of the trust party to this Agreement of Purchase and Sale and shall not be personally binding upon, nor shall any resort be had to the private properties of, any of the trustees, investment managers, any general partners thereof, or any employees or agents of the trustees or investment managers. All documents to be executed by Seller shall also contain the foregoing exculpation. 20 9.25 Purchaser Exculpation Clause.
