The total value of the consideration (the "Aggregate Consideration") to be received by the Members from the Partnership, in exchange for the First Commercial Partnership Interests, shall be Forty Eight Million Five Hundred Thousand Dollars ($48,500,000), as adjusted pursuant to Paragraph 7 of this Agreement. The amount of the Aggregate Consideration which is payable to the Members shall be reduced by the amount of principal and accrued interest secured by the Mortgage Debt on the Real Property as of the Closing Date which is paid off under Paragraph 3(b) below or which is assumed by the Partnership. Such reduced Consideration shall be called the "Net Consideration."

In the event that the Members elect, pursuant to subparagraph (d) below, to receive all of the Consideration in Units in exchange for the contribution of the Partnership Interests, the Escrow Agent shall release the Deposit to the Partnership at the Closing. (b) At the Closing, the Partnership shall deliver in cash sufficient funds to payoff all of the debt on the Real Property which is listed on Exhibit "G" attached hereto (the "Mortgage Debt") provided, however, that amount of such funds shall not exceed an amount equal to 93% of the Aggregate Consideration. -7- (c) (i) The balance of the Initial Consideration shall be paid to the Members at the Closing and the making of the Initial Contribution by wire transfer of immediately available funds to an account designated by the Members. (ii) The Subsequent Consideration shall be paid to the Initial Members upon the making of the Subsequent Contribution, by wire transfer of immediately available funds to an account designated by the Initial Members. (d) In lieu of receiving the cash Consideration pursuant to subparagraphs (a) and (c)(i) and (ii) above, the Members may elect, at their option, to receive all or a portion of the cash Consideration in the form of Class A Units of Limited Partnership Interest ("Units") in the Partnership in exchange for the contribution to the Partnership of all or a portion, as the case may be, of the First Commercial Partnership Interests. The Members may make such election by providing the Partnership written notice not later than twenty (20) days prior to the applicable Closing Date. Such election notice shall state the dollar amount of the Consideration to be received in Units. The number of Units issuable in satisfaction of the applicable portion of the Consideration that the Members elect to be so received shall be computed by dividing the aggregate dollar amount of such applicable portion of the Consideration by the Computed Market Price. The term "Computed Market Price" shall mean the average closing price for the Common Shares as reported by the New York Stock Exchange (the "NYSE") for the ten (10) trading day period immediately preceding the Due Diligence Termination Date. The distributions declared by the Partnership in respect of the Class A Units issuable pursuant to this Agreement during the initial calendar quarter in which the Closing occurs shall be pro-rated by the Partnership based on the number of days the Class A Units are outstanding during such quarter. For example, if the Class A Units issuable pursuant to this Agreement are issued on May 1, 1998, each of such Class A Units shall be entitled to receive an amount equal to two-thirds of the amount of the distributions payable to a Class A Unit that was outstanding during the full quarter.

(b) (i) The Partnership has applied for a title insurance commitment (1992 ALTA Form with Creditor's Rights Exclusion Deleted) to be issued by the Title Insurer ("Commitment"), agreeing to issue to the Partnership, upon the Closing, an owner's policy of title insurance as above specified ("Title Policy"). Said Commitments shall agree to insure the proposed title of the Partnership to each of the Real Property subject only to the Permitted Exceptions and such other title exceptions as the Partnership has agreed to accept or is deemed to have accepted pursuant to this Paragraph.

The Partnership's notice of any Title Defects shall be given in writing to the Members no later than the date which is five (5) business days prior to the Due Diligence Termination Date, together with the Commitments and copies of all matters of record raised therein as exceptions thereto, after which -9- the Partnership shall be deemed to have waived any and all Title Defects not so raised, except for Title Defects which are first disclosed to the Partnership in continuations of title issued subsequent to the issuance of the Commitments, unless the Partnership fails to object to same in writing within three (3) business days after the Partnership's receipt of the continuation of title in which the same is disclosed, in which case the Partnership will be deemed to have waived such additional Title Defects. The Members shall have the right, but not the obligation (except as otherwise specifically provided), to cure such Title Defects and, if the Members elect to attempt to cure the Title Defects but have not cured same on or before the Closing Date, then the Closing Date may be extended by the Members at their sole option for up to thirty (30) days to enable the Members to effect such cure. (ii) In the event that either (a) title is not in accordance with the terms of this Agreement, (b) the Members elect not to cure or cause the removal of any exception to title, except as required in subparagraph (iii) below, or (c) if the Members are unable to satisfy any other conditions to the Partnership's obligations under this Agreement, then (except as otherwise specifically provided in subparagraph (iii) below) the sole liability of the Members shall be to (A) direct the Escrow Agent to return the Deposit to the Partnership and (B) reimburse the Partnership for the reasonable charges imposed by the Title Company for preparation of the Commitments (without the issuance of a policy) and for the reasonable fees paid by the Partnership to update the existing surveys and in respect of the Partnership's actual, documented out-of-pocket costs of due diligence, the sum of which shall in no event exceed in the aggregate $45,000 (collectively the "Partnership's Reasonable Costs"), and upon such payments being made, this Agreement shall be deemed canceled and the parties hereto shall be released of all obligations and liabilities hereunder, except as to any provisions which expressly survive a termination of this Agreement; and the Partnership shall have no rights of action against the Members in law or in equity, for damages or, except for the purpose of enforcing the Members's contractual obligations under subparagraph (iii) below, for specific performance. Notwithstanding the foregoing, the Partnership shall have the right to waive any conditions to the Partnership's obligations hereunder, in which event the Members shall make the deliveries provided for herein to the Partnership to the extent that the Members are able so to do, and there shall be no reduction in the Consideration in such event. (iii) Notwithstanding the provisions of the foregoing paragraph, if the condition of title to the Real Property at the Closing is other than that which the Partnership is required or agrees to accept hereunder solely by reason of any mortgages or other monetary liens (hereinafter referred to as "Liens") which can be satisfied or remedied by the payment of a liquidated amount of money, the Members shall not have the right to cancel this Agreement and the Members shall either (aa) discharge, satisfy, or bond the same or (bb) deliver such funds to be held in escrow required by the Title Company, in either event so that the Title Company shall affirmatively insure the full and complete discharge of the foregoing and shall agree to omit the same as an exception to its title insurance policy. -10- (iv) Notwithstanding anything to the contrary contained in this Agreement, the Members shall have no duty nor be required to take any action, to institute any proceedings or to incur any expense (other than as may be expressly required in subparagraph (iii) above) in order to remedy or remove any objections to title or otherwise to render title in accordance with the terms called for in this Agreement. 6.

In addition, any security deposits held by First Commercial for any Lease, together with the interest due thereon, if any and if required under the terms of the Lease or as required by applicable law, shall be credited to or transferred to the Partnership at Closing. If any tenant is in arrears in the payment of rent or additional rent on the Closing Date, rents received from such tenant within ninety (90) days after the Closing Date shall be applied in the following order of priority: (a) to the Partnership, for current unpaid rents and for so long as current rent is due and payable and such tenant is in arrears for current or prior rent arising after Closing, then (b) to the Members for all rent in arrears prior to the Closing Date; and then (c) to the Partnership with no further claim by the Members thereto. (i) Except as herein provided, after Closing, First Commercial and the Partnership are not under any obligation to collect rents in arrears for the benefit of the -15- Members. Any rents which are delinquent or otherwise not paid at the time of Closing, and collected by the Partnership or First Commercial or the Members within ninety (90) days after Closing shall be apportioned as aforesaid and the portion to which the Members are entitled shall be promptly remitted by the Partnership to the Members. Except as provided in Paragraph 7(d)(ii) below, the Members shall have no claim to rents collected ninety (90) days after the Closing Date. The Members retain the right to pursue their remedies against Tenants after Closing for any delinquent rents or other amounts owed to First Commercial which relate to the period prior to the Closing Date (other than proceedings to evict a Tenant or terminate its lease). The Partnership shall not enter into any agreement pursuant to which any sums owed to the Members in respect of any Lease for periods prior to the Closing are reduced, modified or waived. The obligations of the Partnership and First Commercial to collect arrearages shall be limited to commercially reasonable efforts, and First Commercial and the Partnership shall under no circumstance be required to commence litigation against any Tenant to collect the same. (ii) Notwithstanding the foregoing provisions of Paragraph 7(d): at least five (5) days prior to Closing, the Members shall deliver to the Partnership a reasonably detailed statement setting forth, as of the date of Closing (1) the sums collected from Tenants under Leases on account of or in reimbursement of landlord's operating expenses and/or any other payments made by Tenants to landlord on account of sums which are attributable to expenses paid or incurred by the landlord ("Escalation Payments") for the current fiscal year under each such Lease (whether a lease year or calendar or other year); and (2) the amounts paid or incurred by First Commercial during the appropriate fiscal year as aforesaid which First Commercial expects will be paid or reimbursed by Escalation Payments made by Tenants. If First Commercial shall have collected Escalation Payments for periods prior to Closing, whether pursuant to estimates which were in excess of the amounts actually required to be paid, or otherwise, there shall be an adjustment and credit to the Partnership at Closing for such excess. If the charges were not billed or have not been collected as of the date of Closing, then, when the amount of such Escalation Payments is determined and collected by First Commercial from Tenants after Closing, First Commercial will, upon collection, remit to the Members the portion thereof to which the Members are entitled to the date of Closing. After Closing, First Commercial shall have the right, in good faith, to settle or adjust any amount of such Escalation Payments due from any Tenant without the Members' prior consent, provided that such settlement or adjustment applies ratably to all amounts of Escalation Payments due from such Tenant. (e) All leasing commissions due or to become due prior to the Closing Date for any Leases entered into before the date hereof and all amendments, renewals and modifications thereof entered into before the date hereof, shall be paid by First Commercial prior to Closing without contribution by, or reimbursement from, the Partnership. At Closing, the Partnership shall pay or reimburse the Members for any leasing commissions due or to become due prior to Closing for any Leases and for any amendments, modifications or renewals of any Leases entered into after the date hereof which are entered into in accordance with the provisions of Paragraph 15(e) hereof. Except with respect to the commissions for the prospective Lease -16- renewals set forth on Exhibit "M" , the Members shall be solely obligated to pay all leasing commissions payable under all Leases entered into prior to the date hereof (including all amendments, renewals and modifications thereof) which are first due or payable on or after the Closing Date, regardless of the date on which such Leases (including all amendments, renewals and modifications thereof) were executed or any of the leasing commissions therefor earned, subject only to the right of the Partnership to approve any new Leases or amendments, discretionary renewals or modifications of any Leases which are not otherwise permitted pursuant to Paragraph 15(e), below. First Commercial shall be responsible for the costs of, and shall pay or perform prior to Closing any tenant improvements and allowances for work performed or required to be performed (or paid, as applicable) prior to the Closing Date by or on behalf of First Commercial for all Leases (including all amendments, renewals and modifications thereof) entered into on or before the date of this Agreement for any of the Real Property. The Partnership shall assume, pay or reimburse (as applicable) the Members on the Closing Date for the costs of any tenant improvements and allowances for work to first be performed after the Closing Date pursuant to Leases (including all amendments, renewals and modifications thereof) entered into prior to the date of this Agreement and all costs of tenant improvements and allowances incurred by or on behalf of First Commercial in connection with any Leases (including all amendments, renewals and modifications thereof) entered into after the date of this Agreement for any of the Real Property, provided (i) the same were approved by the Partnership or (ii) are permitted under Paragraph 15(e) hereof or (iii) such costs are set forth on Exhibit "C" hereto. (f) Amounts paid or payable as fees or expenses under any of the Licenses shall be prorated as of the Closing Date but all amounts refundable under Licenses shall belong to the Members. (g) The Initial Members shall be solely responsible for the payment of any "roll back taxes" assessed or imposed upon any of the Real Property under the Pennsylvania Farmland and Forest Land Assessment Act of 1974, or Act 515, as amended, or otherwise, which relate to any period prior to the Closing Date, and the Initial Members agree to indemnify, defend and save First Commercial and the Partnership harmless (including attorneys' fees) from and against any claim for such taxes. (h) Miscellaneous income including, without limitation, telephone and vending machine income, if any, shall be prorated as of the Closing Date. (i) All of the provisions of this Paragraph 7 and First Commercial's, the Members' and the Partnership's respective rights and obligations hereunder shall survive the Closing. -17- 8. Possession Of Property. (a) Possession to the Real Property shall be delivered on the Closing Date, subject only to the Permitted Exceptions. (b) All of the provisions of this Paragraph 8 and First Commercial's, the Member's and the Partnership's respective rights and obligations hereunder shall survive the Closing. (c) The Property is being acquired without any employees of First Commercial. An affiliate of the Partnership, however, intends to hire or retain (but is not obligated to hire or retain) for First Commercial three individuals currently employed by First Commercial (and its affiliates) at salary levels consistent with those currently provided by First Commercial, with benefits consistent with that provided by such affiliate to other employees at a location in the Harrisburg area. The salary levels of such employees are as follows: Bookkeeper/Secretary - $640.85/week; Receptionist/Secretary - $556.14/week; and Property Supervisor - $717.79/week. It is anticipated that the responsibilities currently borne by the employees will be subject to modification to insure consistency with the Partnership's existing Asset Management/Tenant Services Program. Closing of the transactions under this Agreement is not conditioned upon any or all of such First Commercial employees accepting employment with an affiliate of the Partnership or continuing with First Commercial after Closing. (d) The Partnership shall cooperate with the Members and First Commercial to insure good tenant retention at the Property and to utilize the expertise of the Members in establishing a market presence and deal flow. However, no restrictions whatsoever will be placed upon the Members after Closing; rather, it is acknowledged that the Members will continue to develop and lease real estate in the Central Pennsylvania market after the Closing, even though such activities may directly or indirectly compete with the Partnership or First Commercial. In no event, however, for a period of three (3) years after Closing will the Members or any affiliate, employee, representative, or agent of any of them, directly or indirectly approach, canvas or solicit any existing tenant of the Property, without specific written authorization from the Partnership (specifically excluding the ability of the Members to respond to tenant initiated request for proposals). First Commercial is currently responding to a request for proposal of Conrad M. Siegel, Inc. for new office space in a building to be constructed by the Members or certain of them. The Members, or certain of them, would be entitled to brokerage commissions in amounts determined in accordance with local practice for all leasing transactions secured by the Members or their affiliates for the benefit of the Partnership after Closing, including current renewals being negotiated by First Commercial or its affiliates (as detailed in Exhibit "N" to this Agreement). -18- 9. Representations Of The Initial Members and The Partnership. (a) The Initial Members hereby represent and warrant, as follows, all of which shall be true and correct at, and as of, the Effective Date: (1) First Commercial is a limited partnership duly organized and validly existing under the laws of the Commonwealth of Pennsylvania, and is in good standing in such state. (2) First Commercial has all necessary power and authority to enter into this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby, without the consent or authorization of, or notice to, any third party, except those third parties to whom such consents or authorizations have been or will be obtained, or to whom notices have been or will be given, prior to the Closing. (3) Except as set forth in Exhibit "O" attached hereto and made a part hereof, there is no litigation, proceeding or action pending or, to the best of First Commercial's knowledge, threatened against or relating to First Commercial or the Property which might materially and adversely affect First Commercial or the Property or which questions the validity of this Agreement or any action taken or to be taken by First Commercial pursuant hereto. (4) Neither the execution of this Agreement nor the consummation of the transactions contemplated hereby will constitute a violation or be in conflict with or constitute a default under any term or provision of First Commercial's limited partnership agreement or any other material agreement, instrument or lease to which First Commercial is a party, subject to any required consents or authorizations of, or notices to, third parties from whom such consents or authorizations will be obtained or to whom notices will be given prior to Closing. (5) True, correct and complete copies of all of the following, together with any modifications or amendments thereof, but only if and to the extent the same are in First Commercial's possession or control, have been or will be delivered, or made available, to the Partnership within five (5) days following the execution of this Agreement: (i) Leases and rent rolls; (ii) Contracts; (iii) leases of equipment, vehicles and other tangible personal property used by First Commercial in connection with the ownership and operation of the Property (the "Personal Property Leases"); (iv) Licenses; (v) surveys; (vi) title reports; (vii) engineering reports; and (viii) environmental reports. (6) To the best of First Commercial's knowledge, (i) all of the Leases, Contracts and Personal Property Leases and Licenses, are in full force and effect, (ii) there has been no action or failure to act by First Commercial or any other party to any Lease, Contract or Personal Property Lease or License which, with the giving of notice or the passage of -19- time or both, would constitute a default in any material respect or a right to terminate; and (iii) First Commercial has not received from any other party written notice with respect to the condition of the Property or the use or repair of the same or of any alleged default by First Commercial under any such Lease, or Personal Property Lease or License. Except as set forth on Exhibit "P", each of the Contracts is terminable at will without penalty or cancellation fee upon no more than thirty (30) days prior written notice but, except as hereinafter expressly provided, unless otherwise directed by the Partnership, the Contracts shall not be terminated by First Commercial as of Closing. Anything in this Agreement to the contrary notwithstanding, any and all existing management agreements and brokerage or leasing agreements shall be terminated as of Closing. First Commercial shall retain or the Partnership shall assume all Contracts which are not terminated at Closing. (7) As of the Closing, there are and shall be no liens against the Real Property arising under the Employee Retirement Income Security Act of 1974, as amended, nor any other compensation or employment related lien or liability or obligation that could become the responsibility of the Partnership or continue to be the responsibility of First Commercial on or after the Closing. The Partnership shall be under no obligation to assume any of First Commercial's employees, it being the sole responsibility and obligation of the Members to provide severance arrangements, if any, for all such employees so that at Closing, there are no employees of First Commercial. (8) To the best of First Commercial's knowledge, there are no public improvements in the nature of off-site improvements or otherwise, which have been ordered to be made and/or which have not heretofore been assessed and, to First Commercial's actual knowledge, there are no special or general assessments currently affecting or pending against the Real Property or any portion thereof. (9) Except as set forth on Exhibit "Q", First Commercial has not been served with written notice that it has been named as a party in any litigation, administrative proceeding or investigation naming First Commercial as a responsible party or potentially responsible party for any liability for clean-up costs, natural resource damages or other damages or liability for prior disposal or release of Hazardous Substances, Hazardous Wastes or other environmental pollutants or contaminants affecting the Real Property. For purposes of this Agreement, "Hazardous Substances" means those elements and compounds which are designated as such in Section 101(14) of the Comprehensive Response, Compensation and Liability Act (CERCLA), 42 U.S.C. Section 9601 (14), as amended, all petroleum products and by-products, and any other hazardous substances as that term may be further defined in any and all applicable federal, state and local laws; and "Hazardous Wastes" means any hazardous waste, residential or household waste, solid waste, or other waste as defined in applicable federal, state and local laws. First Commercial has not received any summons, citation, directive, letter or other written communication, from any governmental or quasi-governmental authority concerning any intentional or unintentional action or omission on First Commercial's part which either (a) resulted in the releasing, spilling, leaking, pumping, pouring, emitting, emptying or -20- dumping of Hazardous Substances or Hazardous Wastes at the Real Property, or (b) related in any way to the generation, storage, transport, treatment or disposal of Hazardous Substances or Hazardous Wastes at the Real Property. (10) The income and expense statements for the Property and the current rent roll which have been delivered by the Members to the Partnership are true, correct and complete in all material respects. (11) First Commercial has received no written notice of any violation of any of the licenses, permits, consents, authorizations, approvals, and certificates of any regulatory, administrative or other governmental agency or body, if any, issued to or held by the First Commercial and related to the ownership or operation of the Property (collectively, the "Permits"), and there is no pending or, to the best of First Commercial's knowledge, threatened proceeding which could result in the revocation or cancellation of, or inability of First Commercial to renew, any Permit. (12) To the best of First Commercial's knowledge, except as set forth in Exhibit "R" attached hereto and made a part hereof: (a) all management fees, leasing commissions and tenant improvement allowances are fully paid, (b) there are no brokerage commissions owing by First Commercial with respect to any of the Leases or otherwise related to the Property which have not been paid, and (c) there are no ongoing or prospective commission or leasing fee obligations. (13) First Commercial has received no written notice from any insurance company which has issued a policy with respect to the Property or by any board of fire underwriters (or other body exercising similar functions) claiming any defects or deficiencies or requesting the performance of any repairs, alterations or other work, and First Commercial will promptly notify the Partnership of any such notice or requirement if such notice is received prior to the Closing. (14) First Commercial is not a "foreign person" and will deliver to the Partnership, at the Closing, a statement certifying that it is not a "foreign person" within the meaning of the Internal Revenue Code of 1986, as amended. (15) First Commercial has not received written notice from any governmental agency or authority of outstanding material violations issued by governmental authorities having jurisdiction over the Real Property. (16) Except as may be set forth in a Lease as specifically noted on Exhibit "C", there are no options, rights of first refusal or conditional sales agreements regarding the purchase and sale of the Real Property. -21- (17) There are no oral or written leases or rights of occupancy or grants or claims of right, title or interest in any portion of the Property other than the leases (the "Leases") listed on the rent roll attached hereto as Exhibit "C". No tenant has advised First Commercial that First Commercial is in default under any of the Leases, or asserted any claim or basis for any claim for free or reduced rent or right of setoff against the landlord or the rent under the Leases, and First Commercial has no actual knowledge of any default or any event which has taken place which, with the passage of time, or the delivery of notice, or both, could become an event of default. First Commercial has the sole right to collect rents under the Leases, and neither such right nor any of the Leases has been assigned, pledged, hypothecated or otherwise encumbered by First Commercial except as additional collateral for the Mortgage Debt. No holder of any such collateral assignment has asserted or exercised any of its right to collect such rents. Each of the Leases is valid and subsisting and in full force and effect, the tenant is in actual possession in the normal course, and the rents set forth in Exhibit "C" are the actual rents, income and charges being collected by First Commercial under the Leases. Any tenant improvements which First Commercial is obligated to complete pursuant to any Lease (or any unsigned lease proposal or lease amendment) have been completed as of this date or shall be completed as of Closing, and all costs therefore have been or shall be paid by First Commercial, prior to Closing and all of First Commercial's work has or shall have been accepted by the Tenant without exception on or before Closing, other than routine punch list items, which items shall remain the responsibility of First Commercial following Closing, and which obligation shall expressly survive Closing. The amount of each security deposit contains, where required by law or otherwise applicable, interest which has accrued in accordance with law. No tenant of the Property under any of the Leases has, and shall not at Closing have, prepaid any rent under any of the Leases for more than one (1) month. Except as otherwise set forth on Exhibit "C", no security deposits by tenants have heretofore been returned or applied to charges against the tenants. (18) To the best of First Commercial's knowledge: (i) the Property and the continued operation and use thereof comply with all applicable requirements of federal, state and local law, and all applicable requirements of governmental bodies or agencies having jurisdiction thereof, and (ii) except as disclosed on Exhibit "S", no portion of the Property lies within a flood hazard area, flood plain or wetland. (19) Except as specifically set forth on the environmental reports attached hereto as Exhibit "T" to the best of First Commercial's knowledge, (i) no Hazardous Substances (defined below) and no Hazardous Wastes (defined below) are present on the Property including, without limitation, asbestos, flammable substances, explosives, radioactive materials, hazardous wastes, toxic substances, pollutants, pollution, contaminant, polychlorinated byphenyls ("PCBs"), urea formaldehyde foam insulation, radon, corrosive, irritant, biologically infectious materials, petroleum product, garbage, refuse, sludge, hazardous or waste materials, and (ii) there has been no use of the Property that may, under any federal, state or local environmental statute, ordinance or regulation, require, at any time, any closure or cessation of the use or occupancy of the Property and/or impose, at any time, upon the owner of -22- the Property any clean-up or other monetary obligation. To the best of First Commercial's knowledge, neither the Property nor any portion thereof, have been identified on the federal CERLIS, the National Priorities List (40 C.F.R. Part 300, App. B) or any state or local list of potential hazardous waste disposal sites or as an industrial establishment. There are no underground storage tanks located on the Property. (20) To the best of First Commercial's knowledge, all adequate utilities, useable public sanitary and storm sewers, public water facilities, electric facilities and, if any, gas facilities (collectively, the "Utilities"), are installed in, and are duly connected to, the Real Property, and can be used without charge except the normal and usual metered utility charges and water and sewer charges. To the best of First Commercial's knowledge, all Utilities required for the operation of the Property either enter the Property through adjoining public streets or, if they pass through adjoining public land, do so in accordance with valid public easements or private easements which will inure to the benefit of the Partnership at no cost to the owner of the Property. All of said Utilities are installed and operating and all installation, connection and "tap-in" charges have been paid for in full. (21) No work has been performed or is in progress at, and no materials have been furnished to the Property which, though not presently the subject of, might give rise to construction, mechanic's, materialmen's, municipal or other liens against the Property or any portion thereof, except that for which full and complete releases have been obtained. If any lien for any such work is filed before Closing, First Commercial shall promptly discharge the same prior to Closing. (22) To the best of First Commercial's knowledge, none of the artwork being a part of the Personal Property was prepared on a "work for hire" basis and none of the artwork was commissioned after 1991. (23) To the best of First Commercial's knowledge, all applicable charges, fees and assessments (including condominium fees, to the extent applicable) and any and all other sums due under declarations, cross-easements and like agreements to which the Property or any portion thereof may be subject, have been paid, and no special assessments thereunder are pending, and all consents and approvals required to be obtained under any such declarations, cross-easements and like agreements have been obtained pursuant to the requirements of such documentation. (24) To the best of First Commercial's knowledge, all debts, liabilities, and obligations of First Commercial arising out of the construction, ownership, and operation of the Property including, but not limited to, construction costs, salaries, taxes, accounts payable and the like, have been paid as they became due and payable and shall continue to be so paid from the date hereof until the Closing Date. -23- (25) There are no equity, revenue, cash flow, profit or other participations or similar rights of lenders, Tenants or other third parties, which apply to the Real Property. (b) Each of the Members who is acquiring Units, on its own behalf, hereby represents and warrants as follows, all of which shall be true and correct on, and as of, the Effective Date: (1) That it has received a copy of the Trust's Annual Reports on Form 10-K, as amended, for the fiscal years ended December 31, 1997 and 1996 (together, the "10-Ks"), the Trust's Quarterly Reports on Form 10-Q, as amended, for the fiscal quarters ended March 31, 1997, June 30, 1997 and September 30, 1997 (collectively, the "10-Qs"), and all Current Reports on Form 8-K filed by the Trust during the period between January 1, 1997 and the date hereof (collectively, the "8-Ks"), the Trust's proxy statement for its annual meeting of shareholders held on May 12, 1997 and a copy of the Partnership Agreement;

(4) That it understands that the certificates evidencing the Securities shall bear a legend indicating that such Securities have not been registered under the Securities Act or any applicable state securities laws and the transferability thereof is subject to compliance with the Securities Act and applicable state securities laws; (5) That it will not sell or otherwise transfer or dispose of any Securities or any portion thereof unless the Securities are registered under the Securities Act and any applicable state securities laws or it obtains an opinion of counsel which is reasonably satisfactory to the Partnership or the Trust, as appropriate, that the Securities may be sold in reliance on an exemption from such registration requirements, and that the Securities and certificates evidencing the same will bear a legend reflecting such restrictions; (6) That it understands that (i) except as expressly set forth in the Registration Rights Agreement attached hereto as Exhibit "K", neither the Partnership nor the Trust has any obligation or intention to register the Securities for resale under any federal or state securities laws and (ii) it therefore may be precluded from selling or -24- otherwise transferring or disposing of any Securities or any portion thereof for an indefinite period of time or at any particular time; (7) That in determining to acquire the Securities, it has relied solely upon its independent investigation, including the advice of its legal counsel and accountants or other financial and tax advisers and has, during the course of discussions concerning the acquisition of the Securities, been offered the opportunity to ask such questions and inspect such documents concerning the Partnership and the Trust and their respective businesses and affairs as it has requested so as to more fully understand the nature of the investment and to verify the accuracy of the information supplied; (8) THAT IT UNDERSTANDS THAT THE ACQUISITION OF THE SECURITIES INVOLVES CERTAIN RISKS, and that it can bear the economic risk of the acquisition of the Securities, including the total loss of its investment; (9) That (i) it has adequate means of providing for its current needs and financial contingencies, (ii) it has no need for liquidity in this investment, (iii) it has no debts or other obligations, and cannot reasonably foresee any other circumstances, that are likely in the future to require it to dispose of the Securities, (iv) all its investments in and commitments to non-liquid investments are, and after its acquisition of the Securities will be, reasonable in relation to its net worth and current needs, and (v) it was not formed for the specific purpose of making an investment in the Securities; (10) That it understands that no federal or state agency has approved or disapproved the Securities, passed upon or endorsed the merits of the offering of the Securities hereunder, or made any finding or determination as to the fairness of the Securities for investment; (11) That it is making an investment without the influence of any general advertising or general solicitation by the Partnership or the Trust; (12) That it understands that the Securities are being offered and distributed in reliance on specific exemptions from the registration requirements of federal and state securities laws and that each of the Partnership and the Trust is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings set forth herein in order to determine the applicability of such exemption and the suitability of First Commercial and the Members to acquire the Securities. In this regard, it understands that Common Shares may only be issued upon the redemption of the Units, if an exception from the registration requirements of the Securities Act is then available for such issuance; (13) It is an accredited investor, as defined in Rule 501(a) of Regulation D adopted under the Securities Act; and -25- (14) The number of Common Shares which are owned by such Member on the date hereof do not exceed that number that is equal to 1% of the number of outstanding Common Shares of the Trust.

Accordingly, in the event that the Partnership has now or hereafter acquires prior to the Due Diligence Termination Date actual knowledge that one or more of the representations and warranties of the Members are not true, no such fact or circumstance known to the Partnership shall be made the basis of a claim by the Partnership of a breach of representation or warranty by a Member, as the case may be. (e) Notwithstanding anything to the contrary contained in this Agreement, in the event any representation, agreement or undertaking made by the Members in this Agreement shall prove to be false and the cost or expense incurred or likely to be incurred by the Partnership as a result thereof shall not exceed $100,000 in the aggregate, such misrepresentation, agreement or undertaking shall be deemed "immaterial" and shall not give rise to any right of the Partnership to terminate or refuse to close under this Agreement or give rise to any right of action for money damages or specific performance and the Partnership hereby waives all its rights, claims and remedies relating thereto. The Partnership's sole remedy in the event any representation, agreement or undertaking of the Members which is discovered by the Partnership at or prior to the Closing herein shall prove to be false and the cost or expense incurred or likely to be incurred by the Partnership as a result thereof exceeds $100,000 shall be to terminate this Agreement by written notice given at or prior to Closing, which notice shall specify in detail the nature of the misrepresentation and identify in detail the costs incurred or likely to be incurred by the Partnership, and thereupon the Partnership shall receive a refund of the Deposit, and First Commercial shall reimburse the Partnership for the Partnership's Reasonable Costs and Due Diligence Costs. To the extent the Partnership has actual knowledge that any representation, agreement or undertaking is false at or prior to the Closing, and does not or is not permitted to terminate this Agreement, the Partnership hereby waives all of its rights, claims and remedies relating thereto. (f) The Partnership hereby represents and warrants as follows, all of which shall be true and correct at, and as of, the Effective Date: (1) The Partnership is a limited Partnership duly formed and validly existing under the laws of the State of Delaware, and is in good standing with the State of Delaware.

This Agreement constitutes, and the other documents and instruments to be -28- delivered by the Partnership and the Trust pursuant hereto when delivered will constitute, the legal, valid and binding obligations of the Partnership and the Trust, as the case may be, enforceable against the Partnership and the Trust in accordance with their respective terms. (3) Neither the execution of this Agreement nor the consummation of the transactions contemplated hereby will (a) violate any provision of any organizational document of the Partnership or the Trust, or (b) constitute a violation of or be in conflict with or constitute a default under any term or provision of any material agreement, instrument or lease to which the Partnership or the Trust is a party. (4) There is no litigation, proceeding or action pending, or, to the best of the Partnership's knowledge, threatened against or relating to the Partnership or the Trust which might materially and adversely affect the ability of the Partnership or the Trust to consummate the transactions contemplated hereby or which questions the validity of this Agreement or any action taken or to be taken by the Partnership or the Trust pursuant hereto. (5) The execution and delivery of this Agreement shall have been approved by the Board of Trustees of the Trust on or prior to the Due Diligence Termination Date and no further action shall thereupon be required on the part of the Partnership or the Trust to consummate the transaction contemplated hereby. The signatories for the Partnership are authorized and empowered to bind the Partnership to this Agreement. (6) Except as otherwise set forth in Paragraph 9(f)(5) above, in connection with the listing application with the NYSE pursuant to Paragraph 17(d) and the registration of the Underlying Shares pursuant to the Registration Rights Agreement attached hereto as Exhibit "K" and as required by any applicable state securities or "blue sky laws", no consent, approval or authorization of, or declaration, filing or registration with, any governmental agency is required in connection with the execution, delivery and performance of this Agreement or the consummation of the transactions contemplated hereunder by the Trust or the Partnership. (7) The Partnership has sufficient funds available to consummate the transactions contemplated by this Agreement, without the necessity of third-party financing other than the Partnership's existing revolving credit facility administered by NationsBank, N.A. The Partnership acknowledges that its obligations hereunder are not conditioned upon any third party financing or capital infusion by another party.

(9) The information contained in the 10-Ks, 10-Qs and 8-Ks were prepared in all material respects in accordance with and complied in all material respects with the requirements of the rules of the Securities and Exchange Commission, and did -29- not at the time that they were filed contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. (10) Since September 30, 1997, there has been no event or development that has had a material adverse effect on the business, assets or financial condition of the Trust and its subsidiaries taken as a whole.

(g) The Initial Members hereby represent and warrant, as follows, all of which shall be true and correct at, and as of, the Effective Date: (1) There is no litigation, proceeding or action pending or, to the best of First Commercial's knowledge, threatened against or relating to the Excluded Assets or the Other Properties (collectively "Other Assets") which might materially and adversely affect First Commercial; (2) First Commercial has not been served with written notice that it has been named as a party in any litigation, administrative proceeding or investigation naming First Commercial as a responsible party or potentially responsible party for any liability for clean-up costs, natural resource damages or other damages or liability for prior disposal or release of Hazardous Substances, Hazardous Wastes or other environmental pollutants or contaminants affecting the Other Assets. First Commercial has not received any summons, citation, directive, letter or other written communication, from any governmental or quasi-governmental authority concerning any intentional or unintentional action or omission on First Commercial's part which either (a) resulted in the releasing, spilling, leaking, pumping, pouring, emitting, emptying or dumping of Hazardous Substances or Hazardous Wastes at the Other Assets, or (b) related in any way to the generation, storage, transport, treatment or disposal of Hazardous Substances or Hazardous Wastes at the Other Assets. -30- (3) First Commercial has not received written notice from any governmental agency or authority of outstanding material violations issued by governmental authorities having jurisdiction over the Other Assets. (4) To the best of First Commercial's knowledge, the Other Assets and the continued operation and use thereof comply with all other applicable requirements of federal, state and local law, and all applicable requirements of governmental bodies or agencies having jurisdiction thereof. (5) (i) To the best of First Commercial's knowledge, no Hazardous Substances and no Hazardous Wastes are present on the Other Assets including, without limitation, asbestos, flammable substances, explosives, radioactive materials, hazardous wastes, toxic substances, pollutants, pollution, contaminant, PCBs, urea formaldehyde foam insulation, radon, corrosive, irritant, biologically infectious materials, petroleum product, garbage, refuse, sludge, hazardous or waste materials, and (ii) there has been no use of the Other Assets that may, under any federal, state or local environmental statute, ordinance or regulation, require, at any time, any closure or cessation of the use or occupancy of the Other Assets and/or impose, at any time, upon the owner of the Other Assets any clean-up or other monetary obligation. To the best of First Commercial's knowledge, neither the Other Assets nor any portion thereof, have been identified on the federal CERLIS, the National Priorities List (40 C.F.R. Part 300, App. B) or any state or local list of potential hazardous waste disposal sites or as an industrial establishment.

(7) First Commercial is not and will not, at Closing, be subject to liabilities of any nature, with respect to the Other Assets, whether matured or unmatured, fixed or contingent, which could reasonably be expected to have, individually or in the aggregate, a material adverse effect upon First Commercial. (8) For the purpose of Paragraph 9(g), all representations and warranties with respect to the Other Properties for the period after First Commercial sold to third parties such Other Property shall be limited such that knowledge shall be based solely on written notice received by First Commercial from third parties. (h) As to any representation or warranty made in this Agreement which is qualified as being to the best knowledge of the Partnership, the Members or First -31- Commercial, it is agreed and understood that such party shall be under no obligation to conduct any independent investigation or inquiry regarding the matters covered by such representation and warranty. (i) All of the representations and warranties set forth in this Paragraph 9 shall be deemed renewed by the applicable Members and the Partnership on the Closing Date of the Initial Contribution, but not on the Closing Date of the Subsequent Contribution (except that the representation and warranties set forth in Paragraphs 9(b) and 9(c)(1) and (2), insofar as such Paragraphs relate to the Members making the Subsequent Contribution, shall be deemed renewed on the Closing Date of the Subsequent Contribution), and shall, as a condition to each party's obligation to close on such date, be recertified by each party as being true and correct in all material respects as of the Closing Date as if made at such time (it being understood that specific, numbered representations and warranties that speak of a specified date shall only continue to speak as of the date so specified). 10. Access To The Property. (a) The Partnership and/or its agents and representatives, during normal business hours and after reasonable advance notice to First Commercial, may enter into the office of First Commercial where its books and records are located and enter upon any of the Real Property from time to time prior to the Closing Date, accompanied by an agent of First Commercial, for purposes of conducting such inspections, investigations and/or studies as the Partnership deems necessary, including, without limitation, financial, operational and historical reviews of the Real Property and First Commercial, physical inspections, lease reviews and environmental reviews and testing, which activities may include test borings and soil samplings (the "Partnership's Due Diligence Activities"). The Partnership's access to the Real Property shall be subject to the rights of the Tenants of any of the Real Property, who shall not be unreasonably disturbed during any such inspection by the Partnership. The Partnership shall not engage in any activity in or about the Real Property which directly or indirectly violates the terms of any governmental or quasi-governmental statute, rule, regulation, order or practice. The Partnership shall not make any physical changes to any of the Real Property, except for test borings and soil samplings which shall be performed only by licensed engineers reasonably acceptable to First Commercial and only after three (3) business days' prior notice to First Commercial. The Partnership may contact any governmental or quasi-governmental authorities concerning the Property without the prior written approval of First Commercial. First Commercial shall have the opportunity to observe any and all action taken by the Partnership or its representatives, consultants, agents, etc. pursuant to this Paragraph 10. All information set forth in any document which First Commercial has granted to the Partnership the express right to review, if any, shall be held in strict confidence until Closing and thereafter in the event Closing does not occur. If the Partnership violates its obligations under this Paragraph 10(a) or in the event of any physical damage to any of the Real Property or any Personal Property resulting, directly or indirectly, from the exercise by the Partnership of its rights under this Paragraph 10(a), the Partnership hereby agrees to restore the Real Property and Personal Property to their -32- respective conditions prior to incurring such damage. The Partnership hereby agrees to indemnify, defend and hold harmless First Commercial from and against all physical damage to any of the Real Property and Personal Property, personal injury and/or any other claims or liability which may occur as a result of the Partnership's (or the Partnership's agents, employees, invitees or licensees) entry or activities upon any of the Real Property. The provisions of this Paragraph 10(a) shall survive Closing or other termination of this Agreement. (b) The Partnership, or any of the Partnership's consultants performing physical tests on the Real Property shall maintain public liability insurance policies (naming First Commercial as an additional named insured with respect to any liability occurring on the Real Property), with combined single limit coverage of at least $1,000,000, insuring against claims arising as a result of the inspections of the Partnership, its agents, employees or such contractors at any of the Real Property. A certificate of insurance evidencing the foregoing coverage shall be delivered to First Commercial prior to the Partnership's or any of the Partnership's consultants' entry on to any of the Real Property. (c) In the event Closing does not occur or this Agreement is terminated, the Partnership shall promptly return to First Commercial any documents obtained from First Commercial or First Commercial's agents and deliver to First Commercial upon request by First Commercial, without charge, copies of all written test results, studies, reports and similar materials obtained by or on behalf of the Partnership relating to any of the Real Property. 11. Due Diligence Period; Additional Provisions. (a) During the period commencing on the Effective Date and ending at 5:00 p.m. E.S.T. on the Due Diligence Termination Date, the Partnership may, subject to the provisions set forth in Paragraph 10 above, review the matters described in Paragraph 10 and all plans and specifications, condition of title (including without limitation the Permitted Exceptions), agreements relating to and the availability of utilities, environmental conditions, the physical condition of the existing Improvements, compliance by the Property with zoning, licensing and all other governmental requirements, Leases for any of the Real Property, operating statements, service contacts, other contracts, loan documentation, and janitorial company operations pertaining to the Property and all other aspects and conditions of the Property and pertaining to First Commercial and First Commercial's past and present activities and operations, which the Partnership may decide to review (collectively also, the "Partnership's Due Diligence Activities"), all as the Partnership shall deem appropriate). The Partnership's Due Diligence Activities may include environmental, mechanical and engineering inspections deemed appropriate by the Partnership, including complete inspection of all roofs and all mechanical systems. All inspections will be conducted by the Partnership only when accompanied by a representative of First Commercial. All such inspections will be scheduled so as to minimize tenant disruption. During the due diligence period the Partnership plans on conducting tenant interviews and agrees to obtain First Commercial's authorization prior to conducting such -33- interviews. In connection with the Partnership's Due Diligence Activities, First Commercial has delivered or will deliver to the Partnership various documents, reports and materials (collectively, the "First Commercial Due Diligence Materials"). THE PARTNERSHIP UNDERSTANDS AND HEREBY ACKNOWLEDGES AND AGREES THAT THE FIRST COMMERCIAL DUE DILIGENCE MATERIALS ARE BEING DELIVERED TO THE PARTNERSHIP WITHOUT ANY REPRESENTATION OR WARRANTY WHATSOEVER BY FIRST COMMERCIAL, THE MEMBERS OR BY THE PREPARER OF SUCH FIRST COMMERCIAL DUE DILIGENCE MATERIALS, WITH THE SOLE EXCEPTION OF ANY REPRESENTATION OR WARRANTY AS TO THE CORRECTNESS, ACCURACY OR COMPLETENESS THEREOF WHICH IS EXPRESSLY SET FORTH IN THIS AGREEMENT. (b) If, as a result of the Partnership's Due Diligence Activities or otherwise, the Partnership shall conclude, for any reason or for no reason, that it does not wish to proceed with the transaction contemplated by this Agreement, it may terminate this Agreement by written notice delivered to and received by the Members on or before 5:00 P.M. E.S.T. on the Due Diligence Termination Date (as to which date time shall be of the essence), with a simultaneous copy thereof to the Escrow Agent. In the event of such timely termination of this Agreement by the Partnership, the Escrow Agent shall make the delivery of funds contemplated under Paragraph 1 of the Escrow Terms, and this Agreement shall thereupon be null and void and of no further force or effect, except as to those matters which expressly survive such termination. (c) First Commercial shall prepare certificates (the "Estoppel Certificates") for execution by the Tenants which shall be either in the form annexed hereto as Exhibit "W" or the form which the Tenants are required to execute and deliver under their Leases. The Initial Members agree to send to all Tenants initially certificates based on the form annexed hereto as Exhibit "W". The Initial Members agree to deliver the Estoppel Certificates to the Tenants promptly after the Effective Date and to use all reasonable and diligent efforts to obtain executed copies of same from such Tenants prior to the Closing. It shall be a condition to the Partnership's obligations hereunder that, at or prior to Closing, Estoppel Certificates shall have been obtained from at least 75% of the Tenants at each Property, including those identified on Exhibit "X" annexed hereto and made a part hereof (the "Identified Tenants"). (d) The Members shall deliver to the Partnership on or before March 31, 1998, the balance sheets and related combined statement of operations, owner's deficit and cash flows of First Commercial for the year ending December 31, 1997 and on or before ten (10) days after the Effective Date, the statement of operations for the period ending February 28, 1998. -34- 12. Condemnation. The Members covenant and warrant that First Commercial has not received any written notice of any condemnation proceeding or other proceeding in the nature of eminent domain in connection with the Real Property, and First Commercial has no knowledge of any threatened condemnation. As used herein, a "material taking" shall mean a taking of either an entire Real Property, more than ten percent (10%) of a building or more than 10% of the parking area of a single Real Property. If, prior to the Closing, any such proceeding is commenced, First Commercial shall promptly notify the Partnership thereof. In the event of a material taking or commencement of proceedings in connection with such a taking, the Partnership may, at its sole option exercised by delivery of written notice thereof within ten (10) days after receipt of such written notice thereof, (x) proceed to Closing as provided in this Paragraph 12 without an abatement of the Consideration and at Closing, First Commercial shall assign to the Partnership, without recourse, all condemnation proceeds paid or payable with respect thereto; or (y) terminate this Agreement with respect to the Property as to which a material taking has occurred, whereupon this Agreement shall terminate with respect to such Real Property and this Agreement shall continue in full force and effect with respect to all of the remaining Real Property, and at Closing, the Partnership shall pay to the Members the Consideration with respect to the remaining Real Property as the parties shall mutually agree upon. Provided the Partnership shall have waived its right to terminate this Agreement with respect to the Real Property so taken, as provided above, First Commercial shall not, from and after the Due Diligence Termination Date, settle or adjust any claims relating to a condemnation without the Partnership's prior approval, which shall not be unreasonably withheld or delayed. 13. Damage By Fire Or Other Casualty. (a) First Commercial shall promptly notify the Partnership of material damage to the Improvements occurring by reason of casualty during the period between the Effective Date and the Closing Date. First Commercial shall timely notify any insurance companies with respect to any damage and shall promptly submit claims for such damage. Provided the Partnership shall have waived its right to terminate this Agreement with respect to the Real Property so damaged, as provided below, First Commercial shall not, from and after the Due Diligence Termination Date, settle or adjust any claims relating to a casualty without the Partnership's prior approval, which shall not be unreasonably withheld or delayed. (b) If (i) less than 10% of a building or less than 10% of a parking area of a single Real Property is damaged by fire or casualty after the Execution Date and the Improvements so damaged are not repaired or restored on or before Closing to substantially the condition existing prior to the damage, and (ii) at the time of Closing, there shall be no abatement or adjustment in the Consideration and, provided the loss or damage is a covered loss under First Commercial's insurance policy, the Partnership shall be required to purchase all of the Real Property in accordance with the terms of this Agreement and, at Closing, First Commercial shall assign to the Partnership, without recourse, all insurance claims and proceeds with respect thereto (less sums theretofore expended, if any, by First Commercial for emergency repairs or barricades) and the Members shall credit the Partnership at Closing with the amount of any -35- applicable deductible. The Members shall have no liability or obligation with respect to the condition of any of the Real Property as a result of any such fire or casualty. If more than 10% of a building or 10% of a parking area of a single Real Property is so damaged and the Improvements so damaged have not been completed as aforesaid, the Partnership may, at its sole option, (x) proceed to Closing as provided in this Paragraph 13(b) without an abatement of the Consideration and at Closing the Members shall assign to the Partnership, without recourse, all insurance claims and proceeds with respect thereto (less sums theretofore expended, if any, by First Commercial for emergency repairs or barricades) and the Members shall credit the Partnership at Closing with the amount of any applicable deductible; or (y) terminate this Agreement with respect to the Property which suffered such damage whereupon this Agreement shall terminate with respect to such damaged Real Property(s) and this Agreement shall continue in full force and effect with respect to all of the remaining Real Property, and at Closing, the Partnership shall pay to the Members the Consideration with respect to the remaining Real Property as the parties shall mutually agree upon. The Partnership shall assign, without recourse, all of its right, title and interest in and to any and all insurance policies and insurance proceeds relating to such of the Real Property for which this Agreement has been terminated. 14. Default. (a) If the Partnership shall default in its obligations to pay the Consideration and complete Closing in accordance with the terms of this Agreement, then, as the Members' sole and exclusive remedy therefor, the Members shall be entitled to retain the Deposit as liquidated and agreed upon damages for the losses and injuries which the Members shall have sustained and suffered as a result of the Partnership's default, and thereupon this Agreement and the Partnership's obligations hereunder shall be terminated except as expressly provided in this Agreement. It is agreed that the provisions of this Paragraph 14(a) for liquidated and agreed upon damages are a bona fide provision for such and are not a penalty, the parties understanding that by reason of the withdrawal of the Real Property from sale to the general public at a time when other parties would be interested in purchasing such Real Property, that the Members shall have sustained damages which will be substantial, but will not be capable of determination with mathematical precision. Therefore, this provision for liquidated and agreed upon damages has been incorporated as part of this Agreement as a provision beneficial to both parties. (b) If the Members shall default in their obligation to deliver any of items described in Paragraph 5 hereof, upon the Partnership's (i) tender of the Initial Consideration and (ii) compliance with all of the material terms and conditions of this Agreement, the Partnership shall have the sole options of (x) terminating this Agreement and receiving the return of the Deposit, together with payment by the Initial Members of the Partnership Reasonable Costs, not to exceed in the aggregate Forty-Five Thousand ($45,000) or (Y) to seek specific performance of the obligations of the Members and First Commercial under this Agreement with no reduction of the Consideration which is to be paid to the Members. If the Partnership elects to terminate this Agreement, upon payment of the sums described above, -36- First Commercial and the Members shall be released and relieved of any further liability and this Agreement shall thereupon be null and void. 15. Operations Between the Effective Date and the Closing. Between the Effective Date and the Closing: (a) First Commercial shall operate the Property in the same general manner as First Commercial has operated the Property during the immediately preceding six (6) month period, paying all costs and expenses as they come due, and in any event prior to Closing, and maintaining all insurance coverage currently in force. (b) First Commercial shall comply with all of the obligations of landlord under the Leases and all other agreements and contractual arrangements affecting the Real Property by which First Commercial is bound or to which the Real Property, or any of them, are subject. (c) First Commercial shall notify the Partnership promptly of First Commercial's receipt of any notice from any party alleging that First Commercial is in default of its obligations under any of the Leases or any Permit or agreement affecting the Real Property, or any portion or portions thereof. (d) No contract for or on behalf of or affecting the Real Property shall be negotiated or entered into which cannot be terminated by First Commercial upon the Closing without the payment of a specific charge, cost, penalty or premium for such termination. (e) Except with the prior written consent of the Partnership, which the Partnership agrees it shall not unreasonably withhold, condition or delay, First Commercial shall not enter into any new leases for any portion of the Real Property. Any new lease shall be on the Partnership's customary form (which may vary to reflect customary negotiated revisions thereto), or such other form which is reasonably acceptable to the Partnership. Further, except with the prior written consent of the Partnership, which the Partnership agrees it shall not unreasonably withhold, condition or delay, or as set forth above, First Commercial shall not amend, extend (except where required under the terms of the Lease in question), terminate (except by reason of a tenant's default), accept surrender of, or permit any assignments or subleases of, any of the Leases (except as may be required under such Lease), nor accept any rental more than one (1) month in advance (exclusive of any security deposit). (f) First Commercial shall not make or permit to be made any capital improvements or additions to the Real Property, or any portion thereof, without the prior written consent of the Partnership, except those made by First Commercial pursuant to the express requirements of this Agreement, those made by tenants pursuant to the right to do so under their Leases, or by First Commercial if required by applicable law or ordinance, or as required under any Lease. -37- (g) First Commercial shall timely bill all tenants for all rent billable under Leases, and use commercially reasonable efforts to collect any rent in arrears. (h) First Commercial shall notify the Partnership of any tax assessment disputes (pending or threatened) prior to Closing, and from and after the Due Diligence Expiration Date, First Commercial agrees not to seek any changes in the real estate tax assessment, nor settle, withdraw or otherwise compromise any pending claims with respect to tax assessments relating to the current or any subsequent year, without the Partnership's prior written consent, which shall not be unreasonably withheld, delayed or conditioned. If any proceedings shall result in any reduction of assessment and/or tax for the tax year in which the Closing occurs, it is agreed that the amount of tax savings or refund for such tax year, less the reasonable fees and disbursements in connection with such proceedings, shall be apportioned between the parties as of the date real estate taxes are apportioned under this Agreement. All refunds relating to any tax year prior to the Closing shall be the sole property of First Commercial, and all refunds relating to any year subsequent to the year in which Closing occurs shall be the sole property of the Partnership. Each party agrees to promptly remit to the other any refund received by it which is the property of the other. (i) First Commercial shall notify the Partnership promptly of the occurrence of any of the following: (i) Receipt of notice from any governmental or quasi- governmental agency or authority or insurance underwriter relating to the condition, use or occupancy of the Real Property, or any portion thereof; (ii) Receipt of any notice of default from any tenant or from the holder of any lien or security interest in or encumbering the Real Property, or any portion thereof; (iii) Notice of any actual or threatened litigation against First Commercial or affecting or relating to the Real Property, or any portion thereof which may materially and adversely affect the Real Property or First Commercial's ability to consummate the transactions contemplated by this Agreement; or (iv) Vacancy of any demised Property by a tenant, other than in accordance with a scheduled lease termination. -38- 16.

In any circumstances in which the Indemnified Party undertakes to control the Third Party Action as provided in this paragraph, it shall (i) not enter into any resolution or other compromise involving monetary damages without obtaining the prior written consent of the Indemnifying Party provided, however that in the case of the Partnership or the Trust as the Indemnified Party, such written consent may not be withheld if it would interfere with the Partnership's or the Trust's, business operation and (ii) keep the Indemnifying Party informed on an ongoing basis of the status of such Third Party Action and shall deliver to the Indemnifying Party, copies of all documents related to the Third Party Action reasonably requested by the Indemnifying Party.
