                           title matters that appear on the Title Commitment or

                           by Buyer or any Buyer Representatives, and (ii) such
                           Title Objections are either (A) liens evidencing
                           monetary encumbrances (other than liens for
                           non-delinquent general real estate taxes for the
                           current year which are to be apportioned between
                           Buyer and Seller), or (B) liens created or suffered
                           to exist by Seller or its agents and affiliates but
                           only to the extent such liens are created after the
                           date of this Agreement in violation of Section 4.2.3
                           (collectively, the "Required Exceptions"). In
                           addition, Seller shall remove such Title Objections
                           as Seller may elect to remove, or elect to cause to
                           be removed at its expense, as set forth in subsection
                           (c) below.

                  (c)      To the extent that the same do not constitute
                           Required Exceptions, Seller shall notify Buyer in
                           writing within fifteen (15) business days after
                           receipt of Buyer's notice of Title Objections (but in
                           any event, prior to the Closing Date) whether Seller
                           elects to remove the same. If Seller elects not to
                           remove one or more of such Title Objections, then
                           within five (5) business days after Seller's election
                           (but in any event, prior to the Closing Date) , Buyer
                           may elect in writing to either (i) terminate this
                           Agreement, in which event the Deposit shall be paid
                           to Buyer, and thereafter, the parties shall have no
                           further rights or obligations hereunder except for
                           obligations that expressly survive the termination of
                           this Agreement, or (ii) waive the Title Objections
                           which Seller has elected not to remove, in which
                           event the Closing shall occur as herein provided
                           without any reduction of or credit against the
                           Purchase Price on account of such Title Objections.
                           Any such Title Objection so waived (or deemed waived)
                           by Buyer shall be deemed to constitute an additional
                           Permitted Exception.

                                       7


                  (d)      If Seller is unable, after using good faith,
                           commercially reasonable efforts, to remove any
                           Required Exceptions or other Title Objections (other
                           than monetary liens or encumbrances, which Seller
                           shall in all events be obligated to remove) that it
                           has previously elected to remove prior to the
                           Closing, Buyer may at Closing elect either to (a)
                           terminate this Agreement, in which event the Deposit
                           shall be paid to Buyer together with all of Buyer's
                           reasonable and verified costs and expenses, including
                           without limitation legal, environmental, title and
                           other fees incurred in connection with this Agreement
                           and proceeding with the transactions covered by this
                           Agreement, but not more than $50,000 (the
                           "Termination Expenses") and thereafter, the parties
                           shall have no further rights or obligations hereunder
                           except for obligations which expressly survive the
                           termination of this Agreement, or (b) waive such
                           Title Objections, in which event the Closing shall
                           occur as herein provided without any reduction of or
                           credit against the Purchase Price (except that Buyer
                           shall be entitled to a credit against the Purchase
                           Price for any monetary liens plus any additional sums
                           required by the Title Company to be escrowed for
                           satisfaction of same). Upon notice to Buyer at least
                           ten (10) days prior to the scheduled Closing, Seller
                           shall be entitled to a reasonable adjournment of the
                           Closing (not to exceed thirty (30) days) for the
                           purpose of the removal of any Required Exceptions or
                           other Title Objections (other than monetary liens),
                           which removal may be effected by the issuance of
                           title insurance eliminating or insuring against the
                           effect of the Title Objections as provided in Section
                           4.2.2.

         4.2.2    Discharge of Title Objections. If on the Closing Date there
                  are any Required Exceptions or any other Title Objections
                  which Seller has elected to pay and discharge, Seller may use
                  any portion of the Purchase Price to satisfy the same,
                  provided Seller shall either (a) deliver to Buyer at the
                  Closing instruments in recordable form and sufficient to cause
                  such Title Objections to be released of record, together with
                  the cost of recording or filing such instruments, or (b) cause
                  the Title Company to insure over the same, without any
                  additional cost to Buyer, whether such insurance is made
                  available in consideration of payment, bonding, indemnity of
                  Seller or otherwise, provided that any such insurance over any
                  matter other than a monetary lien shall be subject to Buyer's
                  approval, which shall not be unreasonably withheld,
                  conditioned or delayed, and which shall be subject to the
                  other requirements for insuring over as provided in the
                  definition of "Permitted Exceptions" in Article 1 above.

                                       8


         4.2.3    No New Exceptions. From and after the date hereof, Seller
                  shall not execute any deed, easement, restriction, covenant or
                  other matter affecting title to the Property unless Buyer has
                  received a copy thereof and has approved the same in writing.
                  If Buyer fails to object in writing to any such proposed
                  instrument within ten (10) business days after receipt of such
                  instrument together with all applicable information and data
                  as is reasonably appropriate to the evaluation of Seller's
                  request, Buyer shall be deemed to have approved the proposed
                  instrument. Buyer shall not unreasonably withhold, condition
                  or delay its approval with respect to any such instrument;
                  provided that such instrument involves no financial burden to
                  Buyer.

4.3      Title Insurance. At Closing, the Title Company shall issue to Buyer the
         Owner's Policy insuring that fee simple title to the Real Property is
         vested in Buyer, subject only to the Permitted Exceptions, and with
         extended coverage over the standard general exceptions. Buyer shall be
         entitled to request that the Title Company provide such endorsements
         (or amendments) to the Owner's Title Policy as Buyer may reasonably
         require, provided that (a) such endorsements (or amendments) shall be
         at no cost to, and shall impose no additional liability on, Seller, (b)
         Buyer's obligations under this Agreement shall not be conditioned upon
         Buyer's ability to obtain such endorsements and, if Buyer is unable to
         obtain such endorsements, Buyer shall nevertheless be obligated to
         proceed to close the Transaction without reduction of or set off
         against the Purchase Price and (c) the Closing shall not be delayed as
         a result of Buyer's request for endorsements.

         tenants and relationships with tenants (but specifically excluding
         Confidential Materials), including without limitation all existing
         physical and environmental reports, plans and specifications in
         Seller's possession or control. Seller shall also provide Buyer and
         Buyer's representatives access to financial records of the Property
         (excluding Confidential Materials) to the extent reasonably necessary
         for Buyer to confirm that the income from the Property meets the REIT
         tests for federal income tax purposes. Buyer shall complete its Due
         Diligence at its sole cost and expense. Buyer shall independently
         inspect and investigate the Property and verify such information with

         or desirable to evaluate fully the Transaction and the physical
         condition and economic status of the Property. Such Due Diligence may
         include, without limitation, Buyer's review and approval, in its sole
         and absolute discretion, of all title matters, applicable land use and
         zoning laws and regulations, the physical condition of the Property,
         leases and contracts affecting the Property and such other items
         related to the Property as Buyer may deem relevant. Seller agrees to
         make employees of Seller's property manager available to Buyer and
         Buyer's Representatives during the Due Diligence Period as reasonably
         requested by Buyer. Buyer shall immediately return the Property to its
         condition existing prior to any tests and inspections performed by
         Buyer's Representatives or consultants. By Buyer's execution of this
         Agreement, Buyer hereby confirms its agreement to indemnify, defend and
         hold each of the Seller Parties free and harmless from and against any
         and all Liabilities (including reasonable attorneys' fees and expenses)
         arising out of or resulting from the entry on the Property and/or the
         conduct of any Due Diligence by Buyer's Representatives or consultants
         at any time prior to Closing, to the extent caused by Buyer, Buyer's
         Representatives or consultants; provided, however, that Buyer's
         obligations under the foregoing indemnity shall not apply to the mere
         discovery or non-negligent disturbance of a pre-existing environmental
         or physical condition at the Property; and provided, further, that
         Seller and Buyer waive against each other any loss or damage to the
         extent covered by casualty or liability insurance maintained by the
         other. Buyer's investigatory rights shall continue beyond the Due
         Diligence Period until Closing or any earlier termination of this
         Agreement, but without the contingency applicable to the Due Diligence
         Period.

                                       9


5.2      As-Is Sale. Buyer acknowledges and agrees that during the Due Diligence
         Period, Buyer shall conduct such Due Diligence as Buyer deems necessary
         or appropriate. In addition, Buyer acknowledges and agrees that (a)
         except for Seller's Warranties and except as otherwise expressly set
         forth in this Agreement, the Property shall be sold, and Buyer shall
         accept possession of the Property on the Closing Date, "AS IS, WHERE
         IS, WITH ALL FAULTS," with no right of setoff or reduction in the
         Purchase Price; (b) except for Seller's Warranties or as otherwise
         expressly set forth in this Agreement, none of the Seller Parties have
         or shall be deemed to have made any verbal or written representations,
         warranties, promises or guarantees (whether express, implied, statutory
         or otherwise) to Buyer with respect to the Property, any matter set
         forth, contained or addressed in the Documents (including without
         limitation the accuracy and completeness thereof) or the results of
         Buyer's Due Diligence; and (c) Buyer shall independently confirm to its
         satisfaction all information that it considers material to its purchase
         of the Property or the Transaction. Buyer expressly understands and
         acknowledges that it is possible that unknown Liabilities may exist
         with respect to the Property, and that Buyer explicitly took such
         possibility into account in determining and agreeing to the Purchase
         Price.

5.3      Termination of Agreement During Due Diligence Period. If Buyer, in its
         sole and absolute discretion, is not satisfied with the results of its

         obligations which expressly survive the termination of this Agreement,
         and Buyer shall be entitled to the return of the Deposit. In the event
         Buyer fails to terminate this Agreement prior to 5:00 p.m. Eastern Time
         on the first business day following the expiration of the Due Diligence
         Period, Buyer shall be deemed to have waived its rights to terminate
         this Agreement in accordance with this Article 5.

                                       10


5.4      Buyer's Certificate. Buyer shall deliver to Seller, at the Closing, a
         certificate in the form of Exhibit C attached hereto and incorporated
         herein by this reference.

                     ARTICLE 6. - ADJUSTMENTS AND PRORATIONS

The following adjustments and prorations shall be made at Closing:

6.1      Lease Rentals.

         6.1.1    Definition of "Rent". For purposes of this Article 6, the term
                  "Rent" shall mean all base rents, percentage rents, additional
                  rent, common area maintenance charges and any tax and
                  operating expense reimbursements and escalations due from the
                  tenants under the Leases.

         6.1.2    Rents. All collected Rents shall be prorated between Seller
                  and Buyer as of 12:01 a.m. on the Closing Date. Seller shall
                  be entitled to all Rents attributable to the period up to but
                  not including the Closing Date. Buyer shall be entitled to all
                  Rents attributable to any period on and after the Closing
                  Date. Rents not collected as of the Closing Date (including
                  percentage rents) shall not be prorated at the time of
                  Closing. After Closing, Buyer shall make a good faith effort
                  for a period not less than twelve (12) months to collect any
                  Rents not collected as of the Closing Date on Seller's behalf
                  and to tender the same (or Seller's share thereof computed in
                  accordance with the provisions of this Agreement) to Seller
                  upon receipt, net of any adjustments due to Buyer (which
                  obligation of Buyer shall survive the Closing and not be
                  merged therein); provided, however, that all Rents collected
                  by Buyer on or after the Closing Date shall first be applied
                  to all amounts due under the Leases at the time of collection
                  (i.e., current Rents and sums due Buyer as the current owner
                  and landlord) with the balance (if any) payable to Seller, but
                  only to the extent of amounts delinquent and actually due
                  Seller. Seller agrees that the invoicing of delinquent tenants
                  on a monthly basis shall constitute a good faith effort and
                  Buyer shall not be obligated to enforce its rights under the
                  Leases, or threaten such enforcement, or to bring any
                  proceedings in a court of law or equity. Buyer shall not have
                  an exclusive right to collect the sums due Seller under the
                  Leases, and Seller hereby retains its rights to pursue any
                  tenant under the Leases for sums due Seller for periods
                  attributable to Seller's ownership of the Property (including,
                  without limitation, any percentage rent that may be due with
                  respect to any period of time prior to Closing, regardless of
                  when the same is to be paid to the owner of the Property
                  pursuant to the terms of the applicable Lease); provided,
                  however, that Seller (i) shall be required to notify Buyer in
                  writing of its intention to commence or pursue such legal
                  proceedings; (ii) shall only be permitted to commence or
                  pursue any legal proceedings after the date which is three (3)
                  months after Closing and shall commence such proceeding, if at
                  all, prior to the 1st anniversary of the Closing Date; and
                  (iii) shall not be permitted to commence or pursue any legal
                  proceedings against any tenant seeking eviction of such tenant
                  or the termination of the underlying lease. The terms of the
                  immediately preceding sentence shall survive the Closing and
                  not be merged therein.

                                       11


         6.1.3    Other Revenues. Revenues from Property operations other than
                  Rents (which shall be prorated as provided in Subsection
                  6.1.2), and security deposits (which will be apportioned as
                  provided in Section 6.7), that are actually collected, shall
                  be prorated between Buyer and Seller as of 12:01 a.m. on the
                  Closing Date. Seller shall be entitled to all such revenues
                  attributable to any period to but not including the Closing
                  Date, and Buyer shall be entitled to all such revenues
                  attributable to any period on and after the Closing Date.
                  After Closing, Buyer shall make a good faith effort for a
                  period not less than six (6) months to collect any such
                  revenues not collected as of the Closing Date on Seller's
                  behalf and to tender the same to Seller upon receipt, net of
                  any adjustments due to Buyer (which obligation of Buyer shall
                  survive the Closing and not be merged therein); provided,
                  however, that all such other revenues collected by Buyer on or
                  after the Closing Date shall first be applied to all amounts
                  that may be due from such payor to Buyer at the time of
                  collection with the balance (if any) payable to Seller, but
                  only to the extent of amounts delinquent and actually due to
                  Seller. Seller agrees that the invoicing of delinquent payors
                  on a monthly basis shall constitute a good faith effort and
                  Buyer shall not be obligated to enforce its rights under the
                  agreements pursuant to which such revenues are due, or
                  threaten such enforcement, or to bring any proceedings in a
                  court of law or in equity. Buyer shall not have an exclusive
                  right to collect such revenues, and Seller hereby retains its
                  rights to pursue any parties for sums due Seller for periods
                  attributable to Seller's ownership of the Property; provided,
                  however, that Seller (i) shall be required to notify Buyer in
                  writing of its intention to commence or pursue such legal
                  proceedings; (ii) shall only be permitted to commence or
                  pursue any legal proceedings after the date which is three (3)
                  months after Closing and shall commence such proceeding, if at
                  all, prior to the 1st anniversary of the Closing Date; and
                  (iii) to the extent any such delinquent payor is a tenant at
                  the Property, shall not be permitted to commence or pursue any
                  legal proceedings against such tenant seeking eviction of such
                  tenant or the termination of the underlying lease. The terms
                  of the immediately preceding sentence shall survive the
                  Closing and not be merged therein. Notwithstanding anything
                  contained herein to the contrary, Buyer and Seller acknowledge
                  and agree that Seller shall be entitled to bill and collect
                  all reconciliations for 2004 common area maintenance charges
                  and taxes owed by tenants to Seller.

         6.1.4    Marketing Funds. Advertising and marketing funds collected by
                  Seller prior to Closing and not expended will be credited
                  against the Purchase Price.

6.2      Reimbursable Lease Expenses. At Closing, Buyer shall reimburse Seller
         for the Reimbursable Lease Expenses to the extent required by the terms
         of Section 10.2.5.

                                       12


6.3      Real Estate and Personal Property Taxes. 6.3.1 Proration of Ad Valorem
         Taxes. Subject to the terms of Section 6.3.4 below, Buyer and Seller
         shall only prorate ad valorem real estate and personal property taxes
         for the Property that are assessed for the Tax Year in which Closing
         occurs. There shall be no proration of ad valorem real estate or
         personal property taxes other than as set forth hereinabove, and, as
         between Buyer and Seller, Buyer agrees that it shall be solely
         responsible for all such ad valorem real estate and personal property
         taxes due and payable after the Closing and Seller shall be solely
         responsible for all such ad valorem real estate and personal property
         taxes attributable to periods prior to the Closing. The proration of
         the ad valorem real estate and personal property taxes assessed for the
         Tax Year in which Closing occurs shall be calculated as follows:

         (a)      Seller shall be responsible for that portion of such taxes
                  equal to (i) the total such taxes assessed for the Tax Year in
                  which Closing occurs, multiplied by (ii) a fraction, the
                  numerator of which shall be the number of days in such Tax
                  Year prior to the Closing Date, and the denominator of which
                  shall be 365; and

         (b)      Buyer shall be responsible for that portion of such taxes
                  equal to (i) the total such taxes assessed for the Tax Year in
                  which Closing occurs, multiplied by (ii) a fraction, numerator
                  of which shall be the number of days in such Tax Year
                  subsequent to and including the Closing Date, and the
                  denominator of which shall be 365.

         Notwithstanding anything herein to the contrary, Seller agrees to
         collect and remit to the appropriate taxing authority all sales and use
         taxes, if any, required by Law to be collected by Seller prior to the
         Closing Date, and Buyer agrees to collect and remit to the property
         taxing authorities all sales and use taxes, if any, required by Law to
         be collected by Buyer on or after the Closing Date. Each party hereby
         agrees to indemnify and hold the other party harmless from and against
         any and all liability such party may incur, including interest,
         penalties and costs, by reason of the failure of the other party to
         collect and remit to the appropriate taxing authorities all sales and
         use taxes required to be collected by such party during its period of
         ownership. The provisions of this paragraph shall survive Closing and
         shall not be merged therein. Seller's indemnity obligation under this
         Section 6.3.1 shall not be subject to, and shall be in addition to, the
         cap on Seller's liability provided for in Section 16.15 of this
         Agreement.

         6.3.2    Insufficient Information. If, at Closing, the real estate
                  and/or personal property tax rate and assessments have not
                  been set for the taxes assessed for the Tax Year in which
                  Closing occurs, then the proration of such taxes shall be
                  based upon the rate and assessments for the preceding Tax
                  Year, and such proration shall be adjusted between Seller and
                  Buyer after Closing upon presentation of written evidence that
                  the actual taxes assessed for the Tax Year in which Closing
                  occurs differ from the amounts used at Closing and in
                  accordance with the provisions of Section 6.8.

                                       13


         6.3.3    Special Assessments. Seller shall pay all installments of
                  special assessments due and payable prior to the Closing Date,
                  and Buyer shall pay all installments of special assessments
                  due and payable on and after the Closing Date. Special
                  assessments, if any, for the month of Closing will be
                  prorated.

         6.3.4    Tenant Reimbursements. Seller and Buyer acknowledge that real
                  estate taxes are due without penalty on December 31 for the
                  preceding October 1 - September 30 fiscal period and in that
                  regard they agree that, notwithstanding any provision in any
                  of the Leases to the contrary, the tax reimbursement payments
                  to be paid by tenants of the Property during the Tax Year in
                  which Closing occurs are to be applied to pay the real estate
                  taxes assessed for such Tax Year and, therefore, Buyer shall
                  not receive a credit at Closing for any amounts due and
                  payable by tenants of the Property prior to the Closing as
                  real estate tax reimbursements (other than real estate tax
                  reimbursements actually received by Seller prior to Closing
                  which are applicable to the month in which Closing occurs or
                  to periods thereafter, which reimbursements shall be prorated
                  between Buyer and Seller.)

6.4      Other Property Operating Expenses. Operating expenses for the Property
         shall be prorated as of 12:01 a.m. on the Closing Date. Seller shall
         pay all utility charges and other operating expenses attributable to
         the Property to, but not including the Closing Date (except for those
         utility charges and operating expenses payable by tenants in accordance
         with the Leases), and Buyer shall pay all utility charges and other
         operating expenses attributable to the Property on or after the Closing
         Date. To the extent that the amount of actual consumption of any
         utility services is not determined prior to the Closing Date, a
         proration shall be made at Closing based on the last available reading,
         and post-closing adjustments between Buyer and Seller shall be made
         within twenty (20) days of the date that actual consumption for such
         pre-closing period is determined, which obligation shall survive the
         Closing and not be merged therein. Seller shall endeavor to obtain
         final meter readings as of the date prior to Closing. If any utility
         charges are paid in advance or in arrears, appropriate prorations shall
         be made as of the Closing Date. Seller shall not assign to Buyer any
         deposits which Seller has with any of the utility services or companies
         servicing the Property. Buyer shall arrange with such services and
         companies to have accounts opened in Buyer's name beginning at 12:01
         a.m. on the Closing Date. Notwithstanding the foregoing terms of this
         section, Seller shall have no obligation to pay (and Buyer shall not
         receive a credit at Closing for) any operating expenses to the extent
         that (x) Buyer is entitled after Closing to reimbursement of operating
         expenses from tenants, or the recovery of any increase in operating
         expenses, from the tenants under the Leases (including payments due
         from tenants for the month in which Closing occurs but which are not
         actually received by Seller prior to Closing), (y) the tenants from
         whom reimbursement is due are not at Closing in default under their
         Leases, and such reimbursements from tenants under the Leases are not
         more than thirty (30) days past due as of the Closing Date, and (z) the
         amount of such reimbursement from the tenants is capable of reasonably
         precise determination as of the Closing, regardless of whether Buyer
         actually collects such reimbursement or increased operating expenses
         from such tenants after Closing, it being understood and agreed by
         Buyer and Seller that (a) as between Buyer and Seller, Buyer shall be
         responsible for payment of all of such operating expenses to the extent
         of the reimbursements due from tenants as aforesaid, and (b) the burden
         of collection such reimbursements shall be solely on Buyer.

                                       14


6.5      Closing Costs. Buyer shall pay the following costs: (a) one-half of all
         premiums and charges in connection with the Owner's Title Policy
         (provided any endorsements shall be solely the responsibility of Buyer)
         issued to Buyer, (b) the cost of preparing the Survey, (c) all
         recording and filing charges in connection with the instrument by which
         Seller conveys the Property, (d) one-half of the Title Company escrow
         and closing charges, (e) one-half of all documentary stamp taxes,
         transfer taxes, deed taxes, sales taxes and similar charges applicable
         to the transfer of the Property to Buyer ("Transfer Taxes"), (f) all
         costs of Buyer's Due Diligence, including fees due its consultants and
         attorneys, and (g) all lenders' fees related to any financing to be
         obtained by Buyer. Seller shall pay the following costs: (a) one-half
         of the Title Company escrow and closing charges, (b) all fees due its
         attorneys, (c) one-half of the premiums for the Owner's Title Policy,
         excluding Buyer's endorsements, and (d) one-half of the Transfer Taxes.
         The obligations of the parties under this Section 6.5 shall survive the
         Closing (and not be merged therein) or any earlier termination of this
         Agreement.

6.6      Apportionment Credit. In the event the apportionments to be made at the
         Closing result in a credit balance (a) to Buyer, such sum shall be paid
         (at Seller's option) at the Closing by giving Buyer a credit against
         the Purchase Price in the amount of such credit balance, or (b) to
         Seller, Buyer shall pay the amount thereof to Seller at the Closing by
         wire transfer of immediately available funds to the account or accounts
         to be designated by Seller for the payment of the Purchase Price.

6.7      Cash Security Deposits. At Closing, Seller shall give Buyer a credit
         against the Purchase Price in the aggregate amount of any unapplied
         cash security deposits then held by Seller under the Leases less any
         administrative or similar charges to which Seller may be entitled under
         applicable Law.

6.8      Gift Certificate Program. Buyer acknowledges that Seller's gift
         certificate program is a company-wide plan. Therefore, no credit will
         be given at Closing for issued and unused gift certificates. Seller
         hereby agrees to honor all gift certificates as they are redeemed,
         however, no transfer of the gift certificate program shall be made.
         Included in this sale is all gift certificate equipment (check-issuing
         equipment) presently used for the gift certificate program.

6.9      Improvement Allowance Credit. At Closing, Seller shall give Buyer a
         credit against the Purchase Price in an amount equal to the aggregate
         tenant improvement allowances provided for in the Tenant Leases that
         have not been paid to tenants, to the extent that such allowances arise
         under Tenant Leases other than New Leases (which are the responsibility
         of Buyer). In calculating the undisbursed allowances, Seller shall be
         entitled to rely upon the statements made by the tenants with respect
         thereto in their respective tenant estoppel certificates.

                                       15


6.10     Delayed Adjustment; Delivery of Operating and Other Financial
         Statements. If at any time following the Closing Date, the amount of an
         item listed in any section of this Article 6 shall prove to be
         incorrect (whether as a result in an error in calculation or a lack of
         complete and accurate information as of the Closing), the party in
         whose favor the error was made shall promptly pay to the other party
         the sum necessary to correct such error upon receipt of proof of such
         error, provided that such proof is delivered to the party from whom
         payment is requested on or before one (1) year after Closing (such
         period being referred to herein as the "Post Closing Adjustment
         Period"). In order to enable Seller to determine whether any such
         delayed adjustment is necessary, Buyer shall provide to Seller the
         relevant operating and financial statements for the Property no later
         than the date one (1) month prior to the expiration of the Post-Closing
         Adjustment Period or as soon thereafter as practicable, but in such
         case the Post Closing Adjustment Period shall be extended until 1 month
         after delivery of such statements. The provisions of this Section 6.11
         shall survive the Closing and not be merged therein.

                              ARTICLE 7. - CLOSING

Buyer and Seller hereby agree that the Transaction shall be consummated as
follows:

7.1      Closing Date. Subject to Seller's right to extend the Closing as
         provided in this Agreement, Closing shall occur on the Closing Date.
         Time is of the essence with respect to the Closing Date.

7.2      Title Transfer and Payment of Purchase Price. Provided all conditions
         precedent to Seller's obligations hereunder have been satisfied, Seller
         agrees to convey the Property to Buyer upon confirmation of receipt of
         the Purchase Price by the Escrow Agent as set forth below. Provided all
         conditions precedent to Buyer's obligations hereunder have been
         satisfied, Buyer agrees to pay the amount specified in Article 3 by

                           is contrary to the representations herein) is
                           referred to as an "Adverse Claim."

                           efforts to have the same satisfied before Closing. If

                           Closing, Seller shall remain responsible for such
                           Adverse Claim(s), such responsibility to survive
                           Closing, and Seller shall have the reasonable right
                           to control any contest and/or negotiations relating
                           thereto, in cooperation with Buyer. Seller's
                           responsibility for such Adverse Claim(s) shall be in
                           addition to, and shall not be included in, Seller's
                           maximum liability as established under Section 14.15
                           below.

                  documents contemplated hereunder to be executed by Buyer have

                  the violation of any Law or any provision of the
                  organizational documents of Buyer or will conflict with any
                  order or decree of any court or governmental instrumentality

                  Board of Trustees of Pennsylvania Real Estate Investment Trust

                  if such approval is not obtained Buyer may terminate this
                  Agreement as in the case of a termination on account of
                  Buyer's Due Diligence reviews, by notice given not later than
                  the expiration of the Due Diligence Period.

                           as expressly set forth in a Lease). Except as set
                           forth on said Exhibit L, to Seller's knowledge, there

                  Buyer or the contents of files maintained by the Designated
                  Employees. There shall be no personal liability on the part of
                  the Designated Employees arising out of any representations or
                  warranties made herein. Seller represents that the Designated
                  Employees are the senior management personnel for the Property
                  (Mr. Moss being the Senior Vice President for the overall
                  Retail Division, and Mr. Light being the Executive Vice
                  President, Retail Division, with responsibility for the Mall
                  Property.)

                                       26


         9.3.3    Seller's Representations Deemed Modified. To the extent that
                  Buyer knows or is deemed to know prior to the expiration of
                  the Due Diligence Period that Seller's representations and
                  warranties are inaccurate, untrue or incorrect in any way,
                  such representations and warranties shall be deemed modified
                  to reflect Buyer's knowledge or deemed knowledge, as the case
                  may be. In addition, the representation and warranty set forth
                  in clause (d) of Section 9.2.2 shall be null and void and of
                  no further force or effect if and to the extent that Buyer
                  receives estoppel certificates from tenants under the Leases
                  that confirm the truth of said representation and warranty.

         9.3.4    Notice of Breach; Seller's Right to Cure. If after the
                  expiration of the Due Diligence Period but prior to the
                  Closing, Buyer or any Buyer's Representative obtains actual
                  knowledge that any of Seller's Warranties are untrue,
                  inaccurate or incorrect in any material respect, Buyer shall
                  give Seller written notice thereof within ten (10) business
                  days of obtaining such knowledge that the same, individually
                  or collectively, are material (as defined below) (but, in any
                  event, prior to the Closing). If at or prior to the Closing,
                  Seller obtains actual knowledge that any of Seller's
                  Warranties are untrue, inaccurate or incorrect in any material
                  respect, Seller shall give Buyer written notice thereof within
                  ten (10) business days of obtaining such knowledge the same,
                  individually or collectively, are material (as defined below)
                  (but, in any event, prior to the Closing). In either such
                  event, Seller shall have the right to cure such
                  misrepresentation or breach and shall be entitled to a
                  reasonable adjournment of the Closing (not to exceed thirty
                  (30) days) for the purpose of such cure. If Seller is unable
                  to so cure any misrepresentation or breach, then Buyer, as its
                  sole remedy for any and all such materially untrue, inaccurate
                  or incorrect material representations or warranties, shall
                  elect either (a) to waive such misrepresentations or breaches
                  of representations and warranties and consummate the
                  Transaction without any reduction of or credit against the
                  Purchase Price (except for the deduction from the Purchase
                  Price of monetary liens as elsewhere provided herein, and for
                  the deduction from the Purchase Price of any other
                  ascertainable damages resulting from the breach of Seller's
                  Warranties in an amount not to exceed $75,000), or (b) to
                  terminate this Agreement by written notice given to Seller on
                  the Closing Date, in which event this Agreement shall be
                  terminated, the Deposit shall be returned to Buyer, and,
                  thereafter, neither party shall have any further rights or
                  obligations hereunder except as provided in the immediately
                  following sentence and in any section hereof that by its terms
                  expressly provides that it survives any termination of this
                  Agreement. If any such Seller's Warranty was, to Seller's
                  knowledge, materially untrue, inaccurate or incorrect at the
                  time such Seller's Warranty was made, and as a result thereof,
                  Buyer elects to terminate this Agreement, then Seller shall
                  reimburse Buyer for its Termination Expenses as defined in
                  Section 4.2.1 (d) above. The untruth, inaccuracy or
                  incorrectness of a Seller's Warranty shall be deemed material
                  only if Buyer's aggregate damages resulting from the untruth,
                  inaccuracy or incorrectness of the representations or
                  warranties, individually or collectively, are reasonably
                  estimated to exceed $75,000.00.

                                       27


         9.3.5    Survival; Limitation on Seller's Liability. Seller's
                  Warranties in Section 9.2 shall survive the Closing and not be
                  merged therein for a period of twelve (12) months, and Seller
                  shall only be liable to Buyer hereunder for a breach of a
                  Seller's Warranty made herein or in any of the documents
                  executed by Seller at the Closing with respect to which a
                  written claim is made by Buyer against Seller on or before the
                  expiration of twelve (12) months after the date of the
                  Closing. Anything in this Agreement to the contrary
                  notwithstanding, the maximum aggregate liability of Seller for
                  breaches of Seller's Warranties herein or in any documents
                  executed by Seller at Closing shall be limited as set forth in
                  Section 14.14 hereof. Notwithstanding the foregoing, however,
                  if the Closing occurs, Buyer hereby expressly waives,
                  relinquishes and releases any right or remedy available to it
                  at law, in equity, under this Agreement or otherwise to make a
                  claim against Seller for damages that Buyer may incur, or to
                  rescind this Agreement and the Transaction, as the result of
                  any of Seller's Warranties being untrue, inaccurate or
                  incorrect if (a) Buyer knew or is deemed to know that such
                  representation or warranty was untrue, inaccurate or incorrect
                  at the time of the Closing, or (b) Buyer receives a confirming
                  estoppel certificate as set forth in Section 9.3.3, or (c)
                  Buyer's damages as a result of such representations or
                  warranties being untrue, inaccurate or incorrect are
                  reasonably estimated to aggregate less than $100,000.00.

                            ARTICLE 10. - COVENANTS

10.1     Buyer's Covenants.  Buyer hereby covenants as follows:

         10.1.1   Buyer's Indemnity; Delivery of Reports. To the extent provided
                  in Section 5.1 above, Buyer hereby agrees to indemnify,
                  defend, and hold Seller and each of the other Seller Parties
                  free and harmless from and against any and all Liabilities
                  (including reasonable attorneys' fees and expenses) arising
                  out of or resulting from the entry on the Real Property and/or
                  the conduct of any Due Diligence by Buyer or any of Buyer's
                  Representatives or consultants at any time prior to the
                  Closing, which indemnity shall survive the Closing (and not be
                  merged therein) or any earlier termination of this Agreement.
                  If this Agreement is terminated for any reason other than
                  Seller's default, Buyer shall deliver promptly to Seller
                  copies of all third party reports commissioned by or on behalf
                  of Buyer or Buyer's Representatives evidencing the results of
                  its Due Diligence and which do not contain confidential or
                  proprietary information relating to Buyer or Buyer's
                  affiliates.

                                       28


         10.1.2   Limit on Government Contacts. Notwithstanding any provision in
                  this Agreement to the contrary, except in connection with the
                  preparation of a so-called "Phase I" environmental report with
                  respect to the Property, or as otherwise mandated by
                  applicable law, Buyer shall not contact any governmental
                  official or representative regarding Hazardous Materials or
                  the environmental condition of the Property without Seller's
                  prior written consent thereto, which consent shall not be
                  unreasonably withheld, conditioned or delayed. In addition, if
                  Seller's consent is obtained by Buyer, Seller shall be
                  entitled to receive at least five (5) days' prior written
                  notice of the intended contact and to have a representative
                  present when Buyer has any such contact with any governmental
                  official or representative; provided that if such five (5) day
                  notice is given, Buyer shall have the right to extend the Due
                  Diligence Period by five (5) additional days.

10.2     Seller's Covenants.  Seller hereby covenants as follows:

         10.2.1   Contracts.

                  (a)      Without Buyer's prior consent, which consent shall
                           not be unreasonably withheld, between the date hereof
                           and the Closing Date, Seller shall not extend, renew,
                           replace or modify any Contract or enter into any new
                           service contract or agreement unless such contract or
                           agreement (as so extended, renewed, replaced or
                           modified) can be terminated by the owner of the
                           Property without penalty on not more than thirty (30)
                           days' notice. Seller shall provide Buyer not less
                           than five (5) business days' prior written notice to
                           provide its consent to any such contract, extension,
                           renewal, replacement or modification. If Buyer fails
                           to object in writing to any such proposed action
                           within such five (5) business day period, Buyer shall
                           be deemed to have approved the proposed action.
                           Buyer's consent shall not be unreasonably withheld,
                           conditioned or delayed.

                  (b)      On or before the Closing, Seller shall terminate any
                           management and exclusive leasing agreements currently
                           in effect with respect to the Property at the sole
                           cost and expense of Seller.

         10.2.2   Maintenance of Property. Except to the extent Seller is
                  relieved of such obligations by Article 12 hereof, between the
                  date hereof and the Closing Date, Seller shall maintain and
                  keep the Property in a manner consistent with Seller's past
                  practices with respect to the Property; provided, however,
                  that subject to Buyer's right to terminate this Agreement
                  prior to the expiration of the Due Diligence Period in
                  accordance with the terms of Article 5 hereof, and subject to
                  Buyer's right of termination respecting a breach of Seller's
                  warranties in Article 9 hereof, Buyer hereby agrees that
                  Seller shall have no obligation to cure any violations of
                  Laws, and any physical conditions which would give rise to
                  violations (collectively, a "Violation"), (a) if the aggregate
                  cost of such cure is estimated to exceed $500,000 or (b) if
                  and to the extent that the cost of curing such Violation is
                  definitively chargeable to the tenants at the Property
                  pursuant to the terms of their respective leases. Between the
                  date hereof and the Closing Date, Seller will advise Buyer of
                  any written notice Seller receives from any governmental
                  authority of the violation of any Laws regulating the
                  condition or use of the Property and if the aggregate cost of
                  such cure is estimated to be $500,000 or less, then to the
                  extent such cost cannot be charged to tenants as aforesaid,
                  Seller agrees to grant Buyer a credit at Closing in the amount
                  of such cost. If (A) Seller does not cure any such Violation,
                  (B) Seller received notice of such Violation after the
                  expiration of the Due Diligence Period, (C) the aggregate cost
                  to cure such Violation is estimated to exceed $500,000, and
                  (D) the cost of curing such Violation may not be charged to
                  the tenants at the Property pursuant to the terms of their
                  respective leases, then Buyer shall have the right, by written
                  notice given to Seller, to terminate this Agreement on or
                  before the Closing Date. If Buyer terminates this Agreement
                  pursuant to this Section 10.2.2, then the Deposit shall be
                  returned to Buyer and this Agreement shall terminate.
                  Following such termination, neither party to this Agreement
                  shall have any further rights or obligations hereunder other
                  than any arising under the immediately preceding sentence or
                  in any section herein which expressly provides that it
                  survives the termination of this Agreement.

                                       29


         10.2.3   Access to Property. Between the date hereof and the Closing
                  Date Seller shall allow Buyer or Buyer's Representatives
                  access to the Property upon reasonable prior notice at
                  reasonable times provided (a) such access does not interfere
                  with the operation of the Property or the rights of tenants;
                  (b) Buyer shall coordinate with Seller and Seller's property
                  manager prior to and during each visit (c/o Mr. John Moss,
                  Telephone (205) 250-8761 Fax: (205) 250-8890, Email:
                  jmoss@colonialprop.com); (d) Seller or its designated
                  representative shall have the right to pre-approve and be
                  present during any physical testing of the Property; and (e)
                  Buyer shall return the Property to the condition existing
                  prior to such tests and inspections. Prior to such time as
                  Buyer or any of Buyer's Representatives or consultants enter
                  the Property, Buyer shall (i) obtain policies of general
                  liability insurance which insure Buyer and Buyer's
                  Representatives and consultants with liability insurance
                  limits of not less than $1,000,000 combined single limit for
                  personal injury and property damage and name Seller and
                  Seller's property manager as additional insureds and which are
                  with such insurance companies, provide such coverages and
                  carry such other limits as Seller shall reasonably require,
                  and (ii) provide Seller with certificates of insurance
                  evidencing that Buyer has obtained the aforementioned policies
                  of insurance. Notwithstanding the foregoing, no consent from
                  or coordination with Seller or Seller's property manager shall
                  be required for contact or communications with tenants of the
                  Property by Buyer or Buyer's representatives.

         10.2.4   Termination of Certain Contracts. If Buyer notifies Seller in
                  writing prior to the Closing Date that Buyer elects to have
                  any Contracts terminated prior to Closing, Seller shall use
                  good faith and reasonable efforts to terminate the Contracts
                  so designated by Buyer effective as of the Closing Date;
                  provided, however, that in no event shall Seller be required
                  by the foregoing to pay any sums (or incur any other
                  liability) to the other parties to said Contracts on account
                  of such termination (but Buyer may at its option advance such
                  sums as may be required for such purpose). If Seller is unable
                  to so terminate the aforementioned Contracts effective as of
                  the Closing Date, then Seller shall assign and Buyer shall
                  assume the same at Closing in accordance with the terms of
                  this Agreement and the Assignment of Intangible Property.

                                       30


         10.2.5   New Leases; Lease Modifications.

                  (a)      Subject to the terms of this Section 10.2.5, Seller
                           shall continue to lease the Property in accordance
                           with Seller's past practices with respect to the
                           Property. From and after the expiration of the Due
                           Diligence Period, Seller shall not, without Buyer's
                           prior written consent (which shall not be
                           unreasonably withheld, conditioned or delayed), (a)
                           enter into a New Lease; (b) modify or amend any Lease
                           (except pursuant to the exercise by a tenant of a
                           renewal, extension or expansion option or other right
                           contained in such tenant's Lease); or (c) consent to
                           any assignment or sublease in connection with any
                           Lease. (Prior to the expiration of the Due Diligence
                           Period, Seller shall consult in good faith with Buyer
                           on any proposed transaction as mentioned in
                           subclauses (a), (b) or (c) immediately preceding).
                           Seller shall furnish Buyer with a written notice of
                           the proposed action, which shall contain information
                           regarding the proposed action that Seller believes is
                           reasonably necessary to enable Buyer to make informed
                           decisions with respect to the advisability of the
                           proposed action. If Buyer fails to object in writing
                           to any such proposed action within five (5) business
                           days after receipt of the aforementioned information,
                           Buyer shall be deemed to have approved the proposed
                           action. If any Lease requires that the landlord's
                           consent be given under the applicable circumstances
                           (or not be unreasonably withheld), then if Seller
                           certifies in good faith that it is required to give
                           consent, Buyer shall be deemed ipso facto to have
                           approved such action. Any notice from Buyer rejecting
                           the proposed action shall include a description of
                           the reasons for Buyer's rejecting the proposed action
                           shall include a description of the reasons for
                           Buyer's rejection. If Buyer rejects the proposed
                           action, Seller nevertheless retains full right, power
                           and authority to execute such documents as are
                           necessary to effect such action, and Seller shall
                           promptly advise Buyer of the same. The foregoing
                           notwithstanding, in the event that Buyer has rejected
                           the proposed action but Seller nonetheless proceeds
                           to carry out such action, Buyer shall have the right,
                           within five (5) business days after receipt of
                           Seller's notice that Seller has taken such action, to
                           elect to terminate this Agreement by the delivery to
                           Seller of a written notice of termination, in which
                           case the Deposit shall be paid to Buyer, Seller shall
                           reimburse Buyer for its Termination Expenses and
                           thereafter, the parties shall have no further rights
                           or obligations hereunder other than any arising under
                           this sentence and any section of this Agreement that
                           expressly provides that it shall survive the
                           termination of this Agreement. If Buyer fails to
                           notify Seller within such time period, Buyer shall be
                           deemed to have fully waived any rights to terminate
                           this Agreement pursuant to this Section 10.2.5 with
                           respect to such action. Seller shall deliver to Buyer
                           a true and complete copy of each such New Lease,
                           renewal or extension agreement, modification or
                           amendment, as the case may be, promptly after the
                           execution and delivery thereof.

                                       31


                  (b)      Lease Enforcement. Seller shall have the right, but
                           not the obligation (except to the extent that
                           Seller's failure to act shall constitute a waiver of
                           such rights or remedies), to enforce the rights and
                           remedies of the landlord under any Lease by summary
                           proceedings or otherwise (including, without
                           limitation, the right to remove any tenant), and to
                           apply all or any portion of any security deposits
                           then held by Seller toward any loss or damage
                           incurred by Seller by reasons of any defaults by
                           tenants, and the exercise of any such rights or
                           remedies shall not affect the obligations of Buyer
                           under this Agreement in any manner or entitle Buyer
                           to a reduction in, or credit or allowance against,
                           the Purchase Price or give rise to any other claim on
                           the part of Buyer. Notwithstanding the foregoing
                           after the expiration of the Due Diligence Period, and
                           prior thereto if Seller has not notified Buyer of the
                           matter in question, (a) Seller shall take no action
                           against any Tenant which leases more than 10,000
                           square feet without the prior written consent of
                           Buyer which may be withheld in its sole discretion
                           (but which shall be given or denied within five (5)
                           business days after request therefor), (b) Seller can
                           so apply security deposits only if a lease is
                           terminated, and (c) to the extent any security
                           deposits are so applied, Seller shall pay over to
                           Buyer any excess between (x) the amounts so applied,
                           and (y) rents and other charges which had accrued and
                           would have been due and payable up to the Closing
                           Date.

                  (c)      Lease Expenses. At Closing, Buyer shall reimburse
                           Seller for any and all Reimbursable Lease Expenses to
                           the extent that the same have been paid by Seller
                           prior to Closing. In addition, at Closing, Buyer
                           shall assume Seller's obligations to pay, when due
                           (whether on a stated due date or accelerated) any
                           Reimbursable Lease Expenses unpaid as of the Closing,
                           and Buyer hereby agrees to indemnify and hold Seller
                           harmless from and against any and all Liabilities
                           (including reasonable attorneys' fees and expenses)
                           with respect to such Reimbursable Lease Expenses
                           which remain unpaid for any reason at the time of
                           Closing, which obligations of Buyer shall survive the
                           Closing and shall not be merged therein. Each party
                           shall make available to the other all records, bills,
                           vouchers and other data in such party's control
                           verifying Reimbursable Lease Expenses and the payment
                           thereof. Notwithstanding anything contained herein to
                           the contrary, Seller shall be responsible for a
                           portion of the Reimbursable Lease Expenses calculated
                           by multiplying the aggregate Reimbursable Lease
                           Expenses for any tenant by a fraction, the numerator
                           of which is the total base rents actually collected
                           by Seller under the New Leasing Document giving rise
                           to the Reimbursable Lease Expenses, the denominator
                           of which is the aggregate base rent due under such
                           New Leasing Document; provided, however, that if
                           Seller's share of the Reimbursable Lease Expenses
                           with respect to any such New Leasing Document exceeds
                           the base rent actually received by Seller pursuant to
                           such New Leasing Document, then Seller's
                           responsibility for such Reimbursable Lease Expenses
                           shall be limited to the base rents actually received
                           by Seller.

                                       32


10.3     Mutual Covenants.

         10.3.1   Publicity. Seller and Buyer each hereby covenant and agree
                  that (a) prior to the Closing neither Seller nor Buyer shall
                  issue any Release (as hereinafter defined) with respect to the
                  Transaction without the prior consent of the other, except to
                  the extent required by applicable Law or the rules or
                  regulations of any governmental agency or securities exchange,
                  and (b) after the Closing, any Release issued by either Seller
                  or Buyer shall be subject to the review and approval of both
                  parties (which approval shall not be unreasonably withheld),
                  except to the extent required by applicable Law or the rules
                  or regulations of any governmental agency or securities
                  exchange. If either Seller or Buyer is required by applicable
                  Law or the rules or regulations of any governmental agency or
                  securities exchange to issue a Release, such party shall, at
                  least one (1) business day prior to the issuance of the same,
                  deliver a copy of the proposed Release to the other party for
                  its review. As used herein, the term "Release" shall mean any
                  press release or public statement with respect to the
                  Transaction or this Agreement.

         10.3.2   Broker. Seller and Buyer expressly acknowledge that Broker has
                  acted as the exclusive broker with respect to the Transaction
                  and with respect to this Agreement, and that Seller shall pay
                  any brokerage commission due to Broker in accordance with the
                  separate agreement between Seller and Broker. Seller agrees to
                  hold Buyer harmless and indemnify Buyer from and against any
                  and all Liabilities (including reasonable attorneys' fees and
                  expenses) suffered or incurred by Buyer as a result of any
                  claims by Broker or any other party claiming to have
                  represented Seller as broker in connection with the
                  Transaction. Buyer agrees to hold Seller harmless and
                  indemnify Seller from and against any and all Liabilities
                  (including reasonable attorneys' fees and expenses) suffered
                  or incurred by Seller as a result of any claims by any party
                  (other than Broker) claiming to have represented Buyer as
                  broker in connection with the Transaction.

                                       33


         10.3.3   Tax Protests; Tax Refunds and Credits. Seller shall have the
                  right to continue and to control the progress of and to make
                  all decisions with respect to any contest of the real estate
                  taxes and personal property taxes for the Property assessed
                  for the Tax Year in which the Closing occurs and all prior Tax
                  Years. Buyer shall have the right to control the progress of
                  and to make all decisions with respect to any tax contest of
                  the real estate taxes and personal property taxes for the
                  Property assessed for all Tax Years subsequent to the Tax Year
                  in which the Closing occurs. All real estate and personal
                  property tax refunds an credits received after Closing with
                  respect to the Property shall be applied in the following
                  order of priority: first, to pay the costs and expenses
                  (including reasonable attorneys' fees and expenses) incurred
                  in connection with obtaining such tax refund or credit;
                  second, to pay any amounts due to any past or present tenant
                  of the Property as a result of such tax refund or credit to
                  the extent required pursuant to the terms of the Leases; and
                  third, apportioned between Buyer and Seller as follows:

                  (a)      with respect to any refunds or credits attributable
                           to real estate and personal property taxes assessed
                           for the Tax Year in which the Closing occurs, such
                           refunds and credits shall be apportioned between
                           Buyer and Seller in the manner provided for in
                           Section 6.3;

                  (b)      with respect to any refunds or credits attributable
                           to real estate and personal property taxes assessed
                           for any period prior to the Tax Year in which the
                           Closing occurs, Seller shall be entitled to the
                           entire refunds and credits: and

                  (c)      with respect to any refunds or credits attributable
                           to real estate and personal property taxes assessed
                           for any period after the Tax Year in which the
                           Closing occurs, Buyer shall be entitled to the entire
                           refunds and credits.

10.4     Survival. The provisions of this Article 10 shall survive the Closing
         (and not be merged therein) or earlier termination of this Agreement.

                  ARTICLE 11. - FAILURE OF CONDITIONS; DEFAULT

11.1     To Seller's Obligations. If, on or before the Closing Date, (i) Buyer
         is in default of any of its obligations hereunder, or (ii) the Closing
         otherwise fails to occur by reason of Buyer's failure or refusal to
         perform its obligations hereunder in a prompt and timely manner, then
         Seller may elect to (a) terminate this Agreement by written notice to
         Buyer; or (b) waive the condition and proceed to close the Transaction.
         If this Agreement is so terminated, then Seller shall be entitled to
         retain, as its sole and exclusive remedy, the Deposit as agreed upon
         and liquidated damages for all loss, damages and expenses suffered by
         Seller, it being agreed that Seller's damages are impractical or
         extremely difficult to ascertain and the amount of the Deposit
         represents a reasonable estimate of the damages which Seller will
         sustain in the event of a default hereunder by Buyer, and thereafter
         neither party to this Agreement shall have any further rights or
         obligations hereunder other than any arising under any section herein
         which expressly provides that it survives the termination of this
         Agreement.

                                       34


11.2     To Buyer's Obligations. If, at the Closing, (i) Seller is in default of
         any of its obligations hereunder, or (ii) the Closing otherwise fails
         to occur by reason of Seller's failure or refusal to perform its
         obligations hereunder in a prompt and timely manner, Buyer shall have
         the right to elect, as its sole and exclusive remedy, to (a) terminate
         this Agreement by written notice to Seller, promptly after which the
         Deposit shall be returned to Buyer, or (b) waive the condition and
         proceed to close the Transaction, or (c) seek specific performance of
         this Agreement by Seller; provided that in case (a) above Buyer shall
         be entitled to reimbursement of its Termination Expenses if and only to
         the extent elsewhere specifically provided in this Agreement, and in
         cases (b) or (c), Buyer shall be entitled to a credit against the
         Purchase Price if and to the extent elsewhere specifically provided in
         this Agreement. As a condition precedent to Buyer's exercise of any
         right it may have to bring an action for specific performance
         hereunder, Buyer must commence such an action within ninety (90) days
         after the scheduled Closing. Buyer agrees that its failure timely to
         commence such an action for specific performance within such ninety
         (90) day period shall be deemed a waiver by Buyer of its right to
         commence an action for specific performance, as well as a waiver by it
         of any right it may have to file or record a notice of lis pendens or
         notice of pendency of action or similar notice against any portion of
         the Property.

                       ARTICLE 12. - CONDEMNATION/CASUALTY

12.1     Condemnation.

         12.1.1   Right to Terminate. If, prior to the Closing Date, all or any
                  significant portion (as hereinafter defined) of the Property
                  is taken by eminent domain (or is the subject of a pending
                  taking which has not yet been consummated), Seller shall
                  notify Buyer in writing of such fact promptly after obtaining
                  knowledge thereof, and, thereafter, either Buyer or Seller
                  shall have the right to terminate this Agreement by giving
                  written notice to the other no later than ten (10) days after
                  the giving of Seller's notice, and the Closing Date shall be
                  extended, if necessary, to provide sufficient time for Buyer
                  or Seller to make such election. The failure by Buyer and
                  Seller to so elect in writing to terminate this Agreement
                  within such ten (10) day period shall be deemed an election
                  not to terminate this Agreement. For purposes hereof, a
                  "significant portion" of the Property shall mean such a
                  portion as shall have a value, as reasonably determined by
                  Seller, in excess of Three Million Dollars ($3,000,000.00), or
                  a condemnation by which an Adverse Lease Condition shall
                  occur. An "Adverse Lease Condition" means a right on the part
                  of one or more Tenants, as a result of casualty or
                  condemnation, to terminate its or their Lease, if more than
                  10,000 square feet or more of space in the aggregate would be
                  affected, or if as a result of a condemnation there was a
                  failure of the Property to comply with the parking or other
                  zoning requirements of applicable law or the requirements of
                  any of the Leases. If either party elects to terminate this
                  Agreement as aforesaid, the provisions of Section 12.4 shall
                  apply.

                                       35


         12.1.2   Assignment of Proceeds. If (a) neither Seller nor Buyer elects
                  to terminate this Agreement as aforesaid if all or any
                  significant portion of the Property is taken, or (b) a portion
                  of the Property not constituting a significant portion of the
                  Property is taken or becomes subject to a pending taking, by
                  eminent domain, there shall be no abatement of the Purchase
                  Price; provided, however, that, at the Closing, Seller shall
                  pay to Buyer the amount of any award for or other proceeds on
                  account of such taking which have been actually paid to Seller
                  prior to the Closing Date as a result of such taking (less all
                  costs and expenses, including attorneys' fees and expenses,
                  incurred by Seller as of the Closing Date in obtaining payment
                  of such award or proceeds) and, to the extent such award or
                  proceeds have not been paid, Seller shall assign to Buyer at
                  the Closing (without recourse to Seller) the rights of Seller
                  to, and Buyer shall be entitled to receive and retain, all
                  awards for the taking of the Property or such portion thereof.

12.2     Destruction or Damage. In the event any of the Property is damaged or
         destroyed prior to the Closing Date, Seller shall notify Buyer in
         writing of such fact promptly after obtaining knowledge thereof. If any
         such damage or destruction (a) is an insured casualty, (b) would cost
         less than Three Million Dollars ($3,000,000.00) to repair or restore,
         and (c) does not involve an Adverse Lease Condition, then this
         Agreement shall remain in full force and effect, and Buyer shall
         acquire the Property upon the terms and conditions set forth herein. In
         such event, Buyer shall receive a credit against the Purchase Price
         equal to the deductible amount applicable under Seller's casualty
         policy less all costs and expenses, including attorneys' fees and
         expenses, incurred by Seller as of the Closing Date in connection with
         the negotiation and/or settlement of the casualty claim with the
         insurer (the "Realization Costs"), and Seller shall assign to Buyer all
         of Seller's right, title and interest in and to all proceeds of
         insurance on account of such damage or destruction. In the event the
         Property is damaged or destroyed prior to the Closing Date and the cost
         of repair would equal or exceed Three Million Dollars ($3,000,000.00)
         or the casualty is an uninsured casualty or involves an Adverse Lease
         Condition, then, notwithstanding anything to the contrary set forth
         above in this section, Buyer shall have the right, at its election, to
         terminate this Agreement. Buyer shall have thirty (30) days after
         Seller notifies Buyer that a casualty has occurred to make such
         election by delivery to Seller of a written election notice (the
         "Election Notice") and the Closing Date shall be extended, if
         necessary, to provide sufficient time for Buyer to make such election.
         The failure by Buyer to deliver the Election Notice within such thirty
         (30) day period shall be deemed an election not to terminate this
         Agreement. In the event Buyer does not elect to terminate this
         Agreement as set forth above, this Agreement shall remain in full force
         and effect, Seller shall assign to Buyer all of Seller's right, title
         and interest in and to any and all proceeds of insurance on account of
         such damage or destruction, if any, and, if the casualty was an insured
         casualty, Buyer shall receive a credit against the Purchase Price equal
         to the deductible amount (less the Realization Costs) under Seller's
         casualty insurance policy.

                                       36


12.3     Insurance. Seller shall maintain the property insurance coverage
         currently in effect for the Property through the Closing Date.

12.4     Effect of Termination. If this Agreement is terminated pursuant to
         Section 12.1 or Section 12.2, the Deposit shall be returned to Buyer.
         Upon such refund, this Agreement shall terminate and neither party to
         this Agreement shall have any further rights or obligations hereunder
         other than any arising under any section herein which expressly
         provides that it shall survive the termination of this Agreement.

12.5     Waiver. The provisions of this Article 12 supersede the provisions of
         any applicable Laws with respect to the subject matter of this
         Article 12.

                              ARTICLE 13. - ESCROW

The Deposit (if any) and any other sums which the parties agree shall be held in
escrow, and any interest earned thereon (herein collectively called the "Escrow
Deposits"), shall be held by the Escrow Agent, in trust, and disposed of only in
accordance with the following provisions:

         (a)      The Escrow Agent shall invest the Escrow Deposits, if in cash,
                  in government insured interest-bearing instruments reasonably
                  satisfactory to both Buyer and Seller or in a mutual fund with
                  assets in excess of One Billion Dollars which invests in
                  government-issued interest bearing instruments reasonably
                  satisfactory as aforesaid, shall not commingle the Escrow
                  Deposits with any funds of the Escrow Agent or others, and
                  shall promptly provide Buyer and Seller with confirmation of
                  the investments made.

         (b)      If the Closing occurs, the Escrow Agent shall deliver the
                  Escrow Deposits to, or upon the instructions of, Seller on the
                  Closing Date and the Escrow Deposits shall be credited on
                  account of the Purchase Price. If in the form of a letter of
                  credit, such letter of credit shall be surrendered to Buyer.

         (c)      If for any reason the Closing does not occur, the Escrow Agent
                  shall deliver the Escrow Deposits to Seller or Buyer only upon
                  receipt of a written demand therefor from such party, subject
                  to the following provisions of this Subsection (c). If for any
                  reason the Closing does not occur and either party makes a
                  written demand upon the Escrow Agent for payment of the Escrow
                  Deposits, the Escrow Agent shall give written notice to the
                  other party of such demand. If the Escrow Agent does not
                  receive a written objection from the other party to the
                  proposed payment within ten (10) days after the giving of such
                  notice, the Escrow Agent is hereby authorized to make such
                  payment. If the Escrow Agent does receive such written
                  objection within such period, the Escrow Agent shall continue
                  to hold such amount until otherwise directed by written
                  instructions signed by Seller and Buyer or a final judgment of
                  a court.

                                       37


         (d)      The parties acknowledge that the Escrow Agent is acting solely
                  as a stakeholder at their request and for their convenience,
                  that the Escrow Agent shall not be deemed to be the agent of
                  either of the parties, and that the Escrow Agent shall not be
                  liable to either of the parties for any action or omission on
                  its part taken or made in good faith, and not in disregard of
                  this Agreement, but shall be liable for its negligent acts and
                  for any Liabilities (including reasonable attorneys' fees and
                  expenses) incurred by Seller or Buyer resulting from the
                  Escrow Agent's mistake of law respecting the Escrow Agent's
                  scope or nature of its duties. Seller and Buyer shall jointly
                  and severally indemnify and hold the Escrow Agent harmless
                  from and against all Liabilities, including reasonable
                  attorneys' fees and expenses, incurred in connection with the
                  performance of the Escrow Agent's duties hereunder, except
                  with respect to actions or omissions taken or made by the
                  Escrow Agent in bad faith, in disregard of this Agreement or
                  involving negligence on the part of the Escrow Agent.

         (e)      Buyer shall pay any income taxes on any interest earned on the
                  Escrow Deposits. Buyer represents and warrants to the Escrow
                  Agent that its taxpayer identification number is
                  ______________________.

         (f)      The Escrow Agent has executed this Agreement in the place
                  indicated on the signature page hereof in order to confirm
                  that the Escrow Agent shall hold the Escrow Deposits, in
                  escrow, and shall disburse the Escrow Deposits, pursuant to
                  the provisions of this Article 13.

                           ARTICLE 14. - MISCELLANEOUS

14.1     Buyer's Assignment. Buyer shall not assign this Agreement or its rights
         hereunder to any individual or entity without the prior written consent
         of Seller, which consent Seller may grant or withhold in its sole
         discretion, and any such assignment shall be null and void ab initio.
         In the event of any permitted assignment by Buyer, any assignee shall
         assume any and all obligations and liabilities of Buyer under this
         Agreement but, notwithstanding such assumption, Buyer shall thereupon
         be released from any further liability hereunder except for indemnity
         liability relating to its access onto the Property as theretofore
         incurred. Seller hereby consents to the assignment by Buyer of this
         contract to any partnership, limited partnership or limited liability
         company directly or indirectly controlled by Buyer or by Pennsylvania
         Real Estate Investment Trust.

14.2     Designation Agreement. Section 6045(e) of the United States Internal
         Revenue Code and the regulations promulgated thereunder (herein
         collectively called the "Reporting Requirements") require an
         information return to be made to the United States Internal Revenue
         Service, and a statement to be furnished to Seller, in connection with
         the Transaction. Escrow Agent is either (x) the person responsible for
         closing the Transaction (as described in the Reporting Requirements) or
         (y) the disbursing title or escrow company that is most significant in
         terms of gross proceeds disbursed in connection with the Transaction
         (as described in the Reporting Requirements). Accordingly:

                                       38


         (a)      Escrow Agent is hereby designated as the "Reporting Person"
                  (as defined in the Reporting Requirements) for the
                  Transaction. Escrow Agent shall perform all duties that are
                  required by the Reporting Requirements to be performed by the
                  Reporting Person for the Transaction.

                  (b)      Seller and Buyer shall furnish to Escrow Agent, in a
                           timely manner, any information requested by Escrow
                           Agent and necessary for Escrow Agent to perform its
                           duties as Reporting Person for the Transaction.

                  (c)      Escrow Agent hereby requests Seller to furnish to
                           Escrow Agent Seller's correct taxpayer identification
                           number. Seller acknowledges that any failure by
                           Seller to provide Escrow Agent with Seller's correct
                           taxpayer identification number may subject Seller to
                           civil or criminal penalties imposed by law.
                           Accordingly, Seller hereby certifies to Escrow Agent,
                           under penalties of perjury, that Seller's correct
                           taxpayer identification number is
                           _________________________________.

                  (d)      Each of the parties hereto shall retain this
                           Agreement for a period of four (4) years following
                           the calendar year during which Closing occurs.

14.3     Survival/Merger. Except for the provisions of this Agreement which are
         explicitly stated to survive the Closing, (a) none of the terms of this
         Agreement shall survive the Closing, and (b) the delivery of the
         Special Warranty Deed, and other Closing documents and instruments by
         Seller and the acceptance thereof by Buyer shall effect a merger, and
         be deemed the full performance and discharge of every obligation on the
         part of Buyer and Seller to be performed hereunder.

14.4     Integration; Waiver. This Agreement, together with the Exhibits hereto,
         embodies and constitutes the entire understanding between the parties
         with respect to the Transaction and all prior agreements,
         understandings, representations and statements, oral or written, are
         merged into this Agreement. Neither this Agreement nor any provision
         hereof may be waived, modified, amended, discharged or terminated
         except by an instrument signed by the party against whom the
         enforcement of such waiver, modification, amendment, discharge or
         termination is sought, and then only to the extent set forth in such
         instrument. No waiver by either party hereto of any failure or refusal
         by the other party to comply with its obligations hereunder shall be
         deemed a waiver of any other or subsequent failure or refusal to so
         comply.

14.5     Governing Law. This Agreement shall be governed by, and construed in
         accordance with, the law of the State of Alabama.

                                       39


14.6     Captions Not Binding; Exhibits. The captions in this Agreement are
         inserted for reference only and in no way define, describe or limit the
         scope or intent of this Agreement or of any of the provisions hereof.
         All Exhibits attached hereto shall be incorporated by reference as if
         set out herein in full.

14.7     Binding Effect. This Agreement shall be binding upon and shall inure to
         the benefit of the parties hereto and their respective successors and
         permitted assigns.

14.8     Severability. If any term or provision of this Agreement or the
         application thereof to any persons or circumstances shall, to any
         extent, be invalid or unenforceable, the remainder of this Agreement or
         the application of such term or provision to persons or circumstances
         other than those as to which it is held invalid or unenforceable shall
         not be affected thereby, and each term and provision of this Agreement
         shall be valid and enforced to the fullest extent permitted by law.

14.9     Notices. Any notice, request, demand, consent, approval and other
         communications under this Agreement shall be in writing, and shall be
         deemed duly given or made at the time and on the date when received by
         facsimile if such date is a business day (provided that the sender of
         such communication shall orally confirm receipt thereof by the
         appropriate parties and send a copy of such communication to the
         appropriate parties within one (1) business day of such facsimile) or
         when personally delivered if such date is a business day as shown on a
         receipt therefor (which shall include delivery by a nationally
         recognized overnight delivery service) or three (3) business days after
         being mailed by prepaid registered or certified mail, return receipt
         requested, to the address for each party set forth below. Any party, by

14.14    Special Provisions. The following special provisions shall be
         applicable to this Agreement and shall supersede any other provisions
         of this Agreement which are inconsistent herewith:

         14.14.1  Assignment to Affiliates. Buyer intends to assign this
                  Agreement, with respect to the Mall Property, to PREIT Gadsden
                  Mall LLC, and with respect to the Office Property to PREIT
                  Gadsden Office LLC, both Delaware limited partnerships; and
                  (without limiting any other provisions applicable to
                  assignments) from and after such assignment the provisions of
                  this Agreement shall be binding upon and shall inure to the
                  benefit of said assignees and their respective successors and
                  assigns. Seller intends to assign certain rights under this
                  Agreement to an intermediary in connection with a tax-free
                  exchange, and no such assignment shall relieve Seller of any
                  obligation under this Agreement.

         14.14.2  Certain Vacant Land.

                  (a)      Seller or its affiliates owns three vacant pieces of
                           land in the immediate vicinity of the Mall Property,
                           one of which is an easement parcel, as generally
                           described or outlined on Exhibit "P" hereto
                           (collectively, the "Vacant Land"). Seller desires
                           that Buyer acquire the Vacant Land as part of its
                           acquisition of the Mall Property and, subject to
                           Buyer's satisfaction with due diligence reviews for
                           the Vacant Land, Buyer desires to acquire same at a
                           date subsequent to the Closing Date. Buyer shall
                           proceed with its due diligence reviews of the Vacant
                           Land promptly following the Closing Date, and in such
                           connection Seller shall promptly deliver to Buyer any
                           plans, descriptions, title documents and other
                           materials relating to the Vacant Land which are in
                           Seller's possession.

                  (b)      Buyer shall acquire the Vacant Land following the
                           completion of Buyer's due diligence and upon at least
                           ten (10) days advance notice to Seller, but in any
                           event within ninety (90) days following the Closing
                           Date, for a price of ONE DOLLAR ($1.00) for each
                           parcel acquired; provided, however, that Buyer shall
                           have the absolute right, in its sole discretion, to
                           decline to acquire any one or more of the parcels
                           comprising the Vacant Land if Buyer is unsatisfied
                           for any reason with the results of its due diligence
                           investigations. Buyer will have the right to acquire
                           one or more of the parcels comprising the vacant land
                           in the name of affiliated entities.

                  (c)      As a further condition of Buyer's obligation to
                           acquire the Vacant Land, the state of title to the
                           Vacant Land shall be good and marketable and
                           insurable as such, subject only to such title
                           exceptions as Buyer may reasonably approve (it being
                           understood that exceptions in the general nature of
                           those applicable to the Mall Property, other than
                           leases, would be deemed acceptable), and the Vacant
                           Land shall be free of all leases, occupancy rights
                           and contracts, brokerage commissions, and the like
                           (other than recorded easement and utility
                           agreements); and, generally, the provisions of the
                           this Agreement shall apply to the Vacant Land
                           (including without limitation applicable closing
                           apportionments), and the closing documents will be
                           the same as set forth herein, in all cases limited
                           accordingly due to the fact that the property
                           conveyed is vacant land and except as applicable the
                           Vacant Land will be sold to Buyer in its "as is"
                           condition.

                                       42


         14.14.3  Arby's Parcel.

                  (a)      A portion of the Mall Property is an Arby's
                           Restaurant on an outlot located across the street
                           from the Mall Property. Adjacent to the Arby's parcel
                           is a twenty (20) foot section of road which serves as
                           access to the Arby's parcel, and immediately
                           adjoining that, to the south, is a thirty (30) foot
                           section of road which is owned by Seller and which
                           adjoins a McDonald's parcel. Seller believes that the
                           twenty (20) foot section of the road was intended to
                           be conveyed to Seller but, through, inadvertence, was
                           retained by a predecessor affiliate of Seller. Buyer
                           has not yet obtained title and survey review of the
                           Arby's parcel and the adjoining twenty (20) foot
                           easement. Further, Arby's has a first right of
                           refusal in its lease to purchase the Arby's parcel.
                           The aforesaid 20 feet and 30 feet widths are
                           approximate.

                  (b)      Arby's has not waived its first right of refusal
                           prior to the date hereof. Accordingly, Buyer and
                           Seller acknowledge and agree that a portion of the
                           purchase price attributable to the Mall Property
                           equal to One Million One Hundred Fifty Three Thousand
                           Seventy Three Dollars ($1,153,073), shall be withheld
                           from the Purchase Price at Closing. In the event
                           Arby's exercises first right of refusal, Seller shall
                           be permitted to convey the Arby's parcel and any
                           rights to the adjoining road easement areas to Arby's
                           for the purchase price of $1,153,073 in accordance
                           with the terms and provisions of the Arby's Lease and
                           such amount shall constitute a permanent reduction of
                           the purchase price for the Mall Property as between
                           Buyer and Seller.

                  (c)      If, following Closing, Arby's fails to exercise its
                           first right of refusal or such right of first refusal
                           lapses (in either case such that the Title Company
                           issues to Buyer an affirmative endorsement to such
                           effect), then upon ten (10) days notice thereof to
                           Buyer, Buyer shall purchase the Arby's parcel,
                           together with the twenty (20) foot easement adjacent
                           thereto and the 30 foot portion of the road owned by
                           Seller, for the purchase price of $1,153,073. Seller
                           has heretofore initiated the necessary notice to
                           Arby's. The conveyance documents will be the same as
                           attached to this Agreement and the provisions of this
                           Agreement shall continue to apply to the Arby's
                           parcel. Buyer shall have the right to acquire title
                           to the Arby's parcel in the name of an affiliate.
                           Notwithstanding the foregoing, Buyer's obligation to
                           acquire the Arby's parcel is contingent upon (i)
                           there having occurred no material adverse change in
                           circumstances applicable to the Arby's parcel from
                           the circumstances in effect as of the date hereof,
                           and (ii) the Title Company issuing affirmative
                           coverage reasonably satisfactory to Buyer for
                           irrevocable and perpetual easement rights over and
                           across the aforesaid 20 foot portion of the roadway
                           for the use of the Arby's parcel, at no additional
                           premium charge to Buyer, and (iii) Buyer being
                           reasonably satisfied with the results of its title
                           and survey review of the Arby's parcel (and in such
                           connection Buyer agrees to register any objections
                           with Seller within ten (10) days after Buyer's
                           receipt of the relevant title and survey
                           information).

                                       43


                  (d)      The thirty (30) foot parcel referenced in Paragraph 3
                           above is currently owned by Seller. The aforesaid
                           twenty (20) feet of this access road, which
                           immediately adjoins the Arby's parcel and over which
                           Seller currently claims easement rights, is currently
                           the subject to a quiet title action filed in Etowah
                           County, Alabama. Seller agrees to proceed with the
                           defense and counterclaims under the quiet title
                           action at Seller's sole cost through conclusion in
                           order to obtain title to the twenty (20) foot portion
                           and Seller shall indemnify and hold Buyer harmless
                           from any liability relating thereto. In the event
                           Seller obtains title to the twenty (20) foot portion
                           of the road and if Buyer acquires the Arby's parcel,
                           Seller agrees to convey the same to Buyer for One and
                           No/100 Dollars ($1.00). Otherwise, the property
                           comprised in the approximately twenty (20) feet of
                           the easement parcel shall be conveyed or owned
                           pursuant to the court order under the quiet title
                           action but (if Buyer acquires the Arby's parcel)
                           Buyer does not thereby agree to any limitation on its
                           easement rights to said portion of the easement
                           parcel.

         14.14.4  P & S Building Fund. On the Closing Date, $400,000.00 of the
                  purchase price for the Office Property (sometimes also
                  referred to herein as the "P & S Building" and such fund being
                  referred to herein as the "P & S Environmental Cost Fund)
                  shall be held and retained by Buyer, without interest, and
                  shall be disbursed to Seller on a monthly basis (or with such
                  other reasonable frequency as Seller desires) as Seller incurs
                  charges for the completion of the environmental work on the P
                  & S Building as set forth below (the "P & S Building
                  Obligations", it being understood that such fund shall not
                  stand as security for Seller's obligations relating to the
                  other portions of the Property); provided that such
                  disbursements shall be made only upon the furnishing from
                  Seller to Buyer of reasonable evidence of the incurring of
                  charges and of performance of the work to which the charges
                  properly apply. As Seller has agreed to be responsible for the
                  P & S Building Obligations, Buyer and Seller acknowledge and
                  agree that the retention of this P & S Environmental Cost Fund
                  is being established in order to provide additional assurance
                  to Buyer that Seller will complete the P & S Building
                  Obligations and also for any indemnification obligations of
                  Seller that may arise prior to Seller's completion of the P &
                  S Building Obligations. To the extent that the charges for
                  completion of the P & S Building Obligations, and any other
                  obligations or liabilities of Seller under this Agreement, are
                  in excess of the P & S Environmental Cost Fund, Seller
                  acknowledges and agrees that it shall be fully responsible for
                  such costs and charges; it being the understanding that the
                  P&S Environmental Cost Fund is security only and is not
                  intended to limit any liability of Seller. Upon the completion
                  by Seller of the P & S Building Obligations in accordance with
                  the requirements of this Agreement, any then remaining balance
                  of the P&S Environmental Cost Fund shall be disbursed to
                  Seller.

                                       44


         14.14.5  Environmental Obligations. Buyer has concerns with respect to
                  certain environmental conditions (collectively referred to as
                  the "Environmental Conditions") existing on the Mall Property
                  and the P & S Building (as set forth in subsections (a)
                  through (e) in this Paragraph). The following sets forth the
                  agreement of both Buyer and Seller regarding Seller's
                  obligation to investigate and remediate the Environmental
                  Conditions, and further sets forth Seller's obligations
                  regarding third-party claims related to or arising from the
                  Environmental Conditions, and Seller's obligation to be
                  legally responsible for any and all penalties, supplemental
                  environmental projects, or similar financial obligations
                  prepared for, imposed by, ordered or issued by a local, state
                  or federal regulatory agency for any and all existing
                  violations of law existing on the Mall Property and/or the P &
                  S Building prior to Closing. All investigative and remedial
                  actions to be taken by Seller as set forth herein shall be
                  known as "Seller's Work".

                  (a)      The Mall Property contains a Lease with McRae's
                           Department Stores. Effective on or about March 18,
                           2005, Seller removed an underground storage tank
                           ("UST") from the McRae's parcel. Upon such removal,

                           releases of fuel from the tank into the environment.
                           A portion of the soil was excavated upon the tank
                           removal, and Seller's consultant is undertaking an
                           investigation of the Mall Property to determine the
                           scope and extent of the contamination from the tank
                           in order to determine what remedial actions are
                           required in accordance with the: applicable Alabama
                           Department of Environmental Management's ("ADEM")
                           statutes and regulations; applicable ADEM guidance
                           documents and directives; applicable federal

                  (b)      A portion of the Mall Property contains a Sears TBA
                           store, and Sears has rented a portion of the Mall
                           Property to conduct all operations related to the TBA
                           store ("the Sears TBA Site"). The Sears TBA Site was
                           the location of a prior release from five USTs which
                           occurred in approximately 1988. In approximately
                           1998, Seller received a NFA letter from ADEM although
                           the NFA letter did not specifically identify the
                           tanks that were covered. Moreover, Seller has been
                           unable to provide Buyer with all documentation that
                           was submitted to ADEM to support ADEM's issuance of
                           the NFA letter. Buyer has conducted environmental due
                           diligence at the Sears TBA Site and has discovered
                           residual contamination from a prior release is
                           located on the Mall Property. Buyer has further
                           determined that there are two in-service and five
                           out-of-service/former hydraulic vehicle lifts with
                           subsurface reservoirs inside the Sears TBA Building
                           and Seller's Consultant has previously identified a
                           release from one of the in-service lifts. Seller
                           shall be solely obligated to undertake and implement
                           all investigative and remedial actions with respect
                           to the Environmental Conditions at the Sears TBA Site
                           referred to in this Paragraph in accordance with
                           Applicable Standards which shall be conducted by an
                           Alabama Registered Professional Engineer ("Seller's
                           Consultant") experienced in soil and groundwater
                           investigations. Seller shall conduct all Work
                           required to obtain a NFA letter from ADEM and Seller
                           will use its best efforts to have ADEM issue a NFA
                           which will be to the benefit of both Seller and
                           Buyer.

                  (c)      Buyer's Consultant has conducted a dye test at the
                           Sears TBA Site and has determined that the floor
                           drains may not be connected to a sanitary sewer
                           system notwithstanding that they are connected to a
                           storm water system. Seller shall conduct an
                           investigation to determine the status of the
                           connection and whether any remediation is required
                           under the Applicable Standards should Seller
                           determine that the floor-drain system is not
                           connected to a sanitary sewer system. If required in
                           accordance with Applicable Standards, Seller shall
                           either properly close and seal all floor drains
                           located in the Sears TBA building or shall cause
                           connection to be made to a sanitary system with all
                           applicable permits and approvals. Seller shall also
                           ensure that any remedial actions, if required under
                           the Applicable Standards, are conducted in order to
                           obtain an unconditional "Letter of Concurrence" from
                           ADEM and Seller shall use its best efforts to obtain
                           such which will be to the benefit of Seller and
                           Buyer.

                                       46


                  (d)      During the conduct of Buyer's Environmental Due
                           Diligence activities at the P & S Building, Buyer
                           discovered certain Environmental Conditions which
                           Seller has agreed to investigate and remediate in
                           accordance with all Applicable Standards. Buyer and
                           Seller further acknowledge and agree that Seller will
                           prepare an operation and maintenance plan ("O& M
                           Plan") in connection with the presence of
                           asbestos-containing materials ("ACM") and lead-based
                           paint at the P & S Building, at Seller's cost and
                           expense, although Buyer will be responsible for the
                           implementation of all activities required under such
                           O & M Plans.

                  (e)      Seller's Work at the P & S building shall include the
                           following actions:

                           (i)      Fuel Oil Storage Tank. There is currently a
                                    heating oil UST located on the east end of
                                    the parking lot. Seller's Environmental
                                    Consultant is currently in the process of
                                    closing the UST in accordance with the
                                    Applicable Standards. Seller shall obtain an
                                    NFA letter for this UST from ADEM and Seller
                                    will use its best efforts to have ADEM issue
                                    a NFA which will be to the benefit of both
                                    Seller and Buyer.

                           (ii)     ACM. Seller's Environmental Consultant has
                                    identified ACM located within the three
                                    levels of the P & S Building. ACM sampling
                                    and analytical results are provided in a
                                    reported dated February 14, 2005, which has
                                    been provided to Buyer's Environmental
                                    Consultant for its review. Seller's
                                    Environmental Consultant will conduct an
                                    additional investigation and sampling events
                                    to document the presence of ACM insulation
                                    on piping or other items in the plenum space
                                    between the suspended ceiling and the
                                    upper-floor decking or roof. Samples will be
                                    taken to assess the materials through
                                    appropriate laboratory analysis. Seller
                                    agrees to conduct all investigative,
                                    abatement and/or remedial activities in
                                    accordance with the Applicable Standards.
                                    Seller will conduct all activities required
                                    by the Applicable Standards during
                                    non-business hours to avoid disruption to
                                    Buyer's business.

                           (iii)    Lead-Based Paint. Seller's Environmental
                                    Consultant has identified lead-based paint
                                    within the P & S Building and sampling and
                                    analytical results are provided in a report
                                    dated February 14, 2005, which has been
                                    provided to Buyer's Environmental Consultant
                                    for its review. Seller's Environmental
                                    Consultant will conduct an additional
                                    investigation and sampling events to
                                    document the presence of lead-based paint or
                                    dust in the P & S Building to determine
                                    whether Seller is obligated to conduct
                                    abatement activities, including removal or
                                    encapsulation, of lead-based paint coated
                                    surfaces pursuant to the Applicable
                                    Standards. Seller agrees to conduct all
                                    investigative, abatement and/or remedial
                                    activities in accordance with the Applicable
                                    Standards. Seller will conduct all
                                    activities required by the Applicable
                                    Standards during non-business hours to avoid
                                    disruption to Buyer's business.

                                       47


                           (iv)     Interior Elevator Pit. Seller's
                                    Environmental Consultant conducted sampling
                                    of the elevator pit and provided a report to
                                    the Buyer dated February 14, 2005. Seller's
                                    Environmental Consultant has determined that
                                    there is a high groundwater table beneath
                                    the P & S Building and that there is
                                    groundwater seepage into the pit. A sump
                                    pump removes the collected groundwater from
                                    the pit which is discharged to the sewer
                                    system. The hydraulic cylinder associated
                                    with the elevator leaks hydraulic fluid that
                                    mixes with the water in the pit. Seller
                                    shall be required to conduct sampling around
                                    the elevator pit to determine whether there
                                    has been a release that requires remediation
                                    pursuant to the Applicable Standards and
                                    shall conduct such remedial action pursuant
                                    to the Applicable Standards to obtain an
                                    unconditional "Letter of Concurrence" from
                                    ADEM and Seller shall use its best efforts
                                    to obtain such which will be to the benefit
                                    of Seller and Buyer. Moreover, Seller shall
                                    obtain any applicable permits that are
                                    required to discharge the oil-contaminated
                                    groundwater into the sewer system from the
                                    applicable regulatory authority.

                           (v)      Former TBA Floor/Drain System. Seller shall
                                    conduct a dye test of the floor-drain system
                                    associated with the former auto repair area
                                    of the P & S Building to determine the
                                    location of the discharge of the floor-drain
                                    system. Seller shall conduct an
                                    investigation to determine the status of the
                                    connection and whether any remediation is
                                    required under the Applicable Standards
                                    should Seller determine, as a result of the
                                    dye test, that the floor-drain system is not
                                    connected to a sanitary sewer system. If
                                    required in accordance with Applicable
                                    Standards, Seller shall either properly

                  (b)      Seller's Work shall be performed with all due haste
                           and in a diligent and professional manner in order to
                           provide the least possible disruption to Buyer's, and
                           its tenants', operations and business conducted at
                           the Mall Property and the P & S Building. Seller
                           understands that it may be necessary to obtain
                           authorization from Buyer's tenants to conduct
                           Seller's Work and, upon notice from Seller, Buyer
                           shall notify any tenant that may be affected by
                           Seller's Work of the schedule and the scope of all
                           activities to be undertaken by Seller. Further,
                           Seller's Work shall be conducted during non-business
                           hours, with respect to the Work set forth in
                           subsections (e)(ii) and (iii), and for any other
                           Seller's Work if reasonably requested by Buyer or an
                           affected tenant to avoid disruption, and Seller shall
                           maintain sufficient liability insurance with respect
                           to all Work with limits of no less than Ten Million
                           Dollars ($10,000,000), and Buyer and its managing
                           agent shall be named as additional insureds on all
                           insurance policies. All contractors contracted by
                           Seller or its Environmental Consultant shall be
                           required to maintain liability insurance with limits
                           of no less than One Million Dollars ($1,000,000) and
                           all contractors shall rely solely upon Seller for
                           payment for all services performed and shall, to the
                           fullest extent permitted, waive the right to file any
                           mechanic's liens against Buyer. Seller shall further
                           defend, indemnify and hold harmless Buyer from any
                           and all claims related to Seller's Work that may be
                           filed by any contractor or third party, and any
                           claims or liability for personal injury or property
                           damage. In the event that Seller fails and refuses,
                           after reasonable notice, to conduct any required
                           Seller's Work, and Buyer provides a reasonable
                           opportunity to cure and complete any such Work, Buyer
                           shall have the option, but not the obligation, to
                           complete such Work and Seller shall indemnify and
                           properly reimburse Buyer for all reasonable costs and
                           expenses incurred in completing such Work.

         14.14.7  Disagreement Relating to Sears TBA Site. Should Seller's
                  Consultant and Buyer's Consultant disagree as to whether
                  Seller's Work at the Sears TBA Site was conducted in
                  accordance with the Applicable Standards, then Seller and
                  Buyer agree to select a neutral Alabama Registered
                  Professional Engineer ("Independent Engineer") with relevant
                  environmental experience, such selection to occur no later
                  than ten (10) days following written notification by either
                  Party as to the disagreement, and the Independent Engineer
                  will be responsible for reviewing all relevant documentation
                  related to Seller's Work to reach an independent decision,
                  which shall be binding upon both Seller and Buyer, as to
                  whether Seller's Work was conducted in accordance with the
                  Applicable Standards. If the Independent Engineer decides that
                  additional or different Work must be conducted by the Seller
                  in order to comply with the Applicable Standards, Seller
                  agrees to conduct all such required Work, and if the
                  Independent Engineer decides that no additional or different
                  Work is required, then Seller shall be entitled to abide by
                  such decision.

         14.14.8  Indemnification. Seller agrees to defend, hold harmless, and
                  indemnify Buyer and its managing agent and their respective
                  principals, officers and directors (with counsel reasonably
                  satisfactory to Buyer) from any and all Environmental Claims

                  Standards, Buyer acknowledges and agrees that Buyer shall
                  thereupon be deemed to release Seller, its principals,

                  be confirmed by supplemental written documentation.
