Item 2. Acquisition or Disposition of Assets.

On April 28, 2003, Pennsylvania Real Estate Investment Trust (together with its affiliated entities, "PREIT") acquired Moorestown Mall, The Gallery at Market East and Exton Square Mall from affiliated companies of The Rouse Company ("Rouse"), and these transactions were conducted by PREIT through an exchange accommodation title holder in accordance with the provisions of Section 1031 of the Internal Revenue Code. On the same date, PREIT deferred the acquisition of Plymouth Meeting Mall and Echelon Mall from Rouse in accordance with the terms of the amended agreements of sale for those malls. Also on April 28, 2003, New Castle Associates acquired Cherry Hill Mall from Rouse in exchange for its interest in Christiana Mall, cash and the assumption by New Castle Associates of mortgage debt on Cherry Hill Mall. As further described below, on that same date, PREIT also acquired an ownership interest in New Castle Associates and an option to acquire the remaining ownership interests.

The aggregate purchase price for PREIT's acquisition of the three malls from Rouse and for its interest in New Castle Associates (including the additional purchase price payable upon exercise of PREIT's option to acquire the remaining interests in New Castle Associates) was $469 million, including approximately $157 million in cash, the assumption of $277 million in non-recourse mortgage debt and $35 million in units of limited partnership interest in PREIT's operating partnership ("OP Units"). All of the OP Units were or will be issued as part of the consideration for PREIT's acquisition of its interest in New Castle Associates. One of the partners of New Castle Associates, Pan American Associates, the former sole general partner and a limited partner of New Castle Associates, is controlled by Ronald Rubin, PREIT's Chairman and Chief Executive Officer, and George Rubin, a trustee of PREIT and President of PREIT's management subsidiaries, PREIT-RUBIN, Inc. and PREIT Services, LLC. If the acquisition of Plymouth Meeting Mall and Echelon Mall from Rouse occurs no later than June 13, 2003, the aggregate purchase price for those two malls (including the ground lessor's interest in the Plymouth Meeting Mall with a price of approximately $8.6 million) is expected to be approximately $79.4 million in cash. If the acquisition of Plymouth Meeting Mall does not occur until after June 13, 2003, the purchase price of the mall (excluding the ground lessor's interest) is expected to be approximately $46.4 million plus the prepayment premium on the mortgage at the time of the acquisition. If the acquisition of Echelon Mall occurs after June 13, 2003, the original purchase price of the mall of approximately $17 million will decrease approximately $225,000 per month for a period of six months and thereafter neither Rouse nor PREIT will have any obligation to sell or purchase, as applicable, the Echelon Mall.

PREIT financed the cash portion of the purchase price through an unsecured $200 million credit facility (the "Acquisition Credit Facility") with Wells Fargo, National Association ("Wells Fargo"). The Acquisition Credit Facility is comprised of a $175 million term loan facility (the "Term Loan") and a $25 million revolving loan facility (the "Revolving Loan"). The Acquisition Credit Facility matures on October 27, 2003, and may be extended for an additional 90 days upon the payment of an extension fee of 0.20% of the amount then outstanding. The Revolving Loan and the Term Loan provide for full recourse to PREIT and its subsidiary guarantors. The fee paid to Wells Fargo for the Term Loan was $1,312,500, and will include an additional 0.25% of the then outstanding Term Loan amount payable unless the Acquisition Credit Facility has been fully repaid and cancelled within 90 days of closing. The fee paid to Wells Fargo for the Revolving Loan was $62,500, plus $125,000 payable upon the earlier of the first advance of the Revolving Loan or October 27, 2003. In addition, there is a fee of 0.125% per annum on the unused portion of the Revolving Loan payable to Wells Fargo quarterly in arrears. At PREIT's option, the Acquisition Credit Facility bears interest at either (1) the Base Rate (the greater of Wells Fargo's prime rate or the Federal Funds Rate plus 0.5%) or (2) the LIBOR rate for which deposits are offered to Wells Fargo for one-, two-, three- or six-month periods, plus margins ranging from 2.5% to 3.0%, depending on PREIT's ratio of Total Liabilities to Gross Asset Value (as defined in the credit agreement for the Acquisition Credit Facility). As of April 28, 2003, the margins for the LIBOR Loans were set at 3.0%.

-2-

The financial covenants are the same as those of PREIT's existing credit facility dated December 28, 2000, agented by Wells Fargo (as modified as described below, the "Existing Credit Facility"), plus two additional covenants providing that PREIT's secured recourse indebtedness may not exceed 15% of its Gross Asset Value and that PREIT may not, without Wells Fargo's approval, incur unsecured Indebtedness (as defined in the credit agreement for the Acquisition Credit Facility) other than under the Acquisition Credit Facility and the Existing Credit Facility or with respect to trade payables. PREIT currently expects to repay the Acquisition Credit Facility primarily with the cash proceeds from the sale of its multifamily portfolio and additional fixed rate non-recourse debt secured by one or more of the malls discussed above and by some of PREIT's existing retail properties. The Acquisition Credit Facility may be prepaid without premium or penalty subject to the payment of customary LIBOR breakage costs.

In connection with the Acquisition Credit Facility, PREIT also entered into an amendment of its Existing Credit Facility, including an amendment of the financial covenant to maintain a ratio of Total Liabilities to Gross Asset Value of 0.70:1 (rather than the previous ratio of 0.65:1), and a modification of the definition of Total Liabilities to exclude the mark-up of assumed debt on the acquired properties resulting from the above-market interest rates on the assumed debt. In addition, the Floating Rate Debt limitation under the Existing Credit Facility was increased from $200,000,000 to $400,000,000. As consideration for these modifications, PREIT agreed to a provision requiring that, if its ratio of Total Liabilities to Gross Asset Value exceeds 0.65:1, the Existing Credit Facility will bear interest at LIBOR plus 190 basis points, which is an increase to the previous range of 130 to 180 basis points. PREIT also agreed to pay each lender under the Existing Credit Facility an amendment fee of 0.15% of each Lender's existing revolving commitment amount.

PREIT's acquisition of its interest in New Castle Associates consisted of acquiring 49% of the aggregate partnership interests in New Castle Associates from partners of New Castle Associates other than Pan American Associates on April 28, 2003, in exchange for an aggregate of 585,422 OP Units. The number of OP Units is subject to specified post-closing adjustments. Simultaneously with this acquisition, PREIT increased its aggregate ownership interest in New Castle Associates to 72.89% by acquiring an additional ownership interest directly from New Castle Associates in exchange for a cash investment in New Castle Associates of approximately $30.8 million (which amount is also subject to specified post-closing adjustments). This cash investment was used by New Castle Associates to pay to Rouse the majority of the cash portion of the purchase price and associated costs for the acquisition of Cherry Hill Mall.

-3-

PREIT also obtained an option, beginning April 30, 2004 and expiring October 27, 2004, to acquire the remaining interests in New Castle Associates, including that of Pan American Associates, in exchange for an aggregate of 609,317 additional OP Units (which amount is subject to specified post-closing adjustments). If PREIT does not exercise this option, the remaining partners of New Castle Associates will have the right, beginning April 28, 2008 and expiring October 25, 2008, to require PREIT to acquire the remaining interests in New Castle Associates in exchange for an aggregate of 670,249 additional OP Units (which amount is also subject to specified post-closing adjustments). Until these call or put rights are exercised or the put right expires unexercised, the remaining partners of New Castle Associates will be entitled to receive cumulative preferred distributions from New Castle Associates on their remaining interests in New Castle Associates in amounts approximating the distributions they would have received had they exchanged all of their interests in New Castle Associates for OP Units on April 28, 2003.

In connection with PREIT's acquisition of its interest in New Castle Associates, Pan American Associates ceased to be a general partner of New Castle Associates and PREIT designated one of its affiliates as the sole general partner. Certain former partners of New Castle Associates not affiliated with PREIT exercised their special right to redeem for cash an aggregate of 261,349 OP Units issued to such partners at closing, and PREIT paid to those partners an aggregate amount of approximately $7.7 million. In addition, PREIT granted registration rights to the partners of New Castle Associates with respect to the PREIT shares underlying the OP Units issued or to be issued to them, other than those redeemed for cash following the closing.

To facilitate the exchange of Christiana Mall for Cherry Hill Mall, PREIT waived any right of first refusal that it may have had with respect to the sale of Christiana Mall by New Castle Associates. Upon the sale of Christiana Mall by New Castle Associates, and before PREIT's investment in New Castle Associates, PREIT's management and leasing agreement for that property was terminated, and PREIT received a brokerage fee of $2 million from New Castle Associates in respect of the exchange of Christiana Mall for Cherry Hill Mall. PREIT also entered into a new management and leasing agreement with New Castle Associates for Cherry Hill Mall, which provides for a fee of approximately 5.25% of all rents and other revenues received by New Castle Associates from the ownership of Cherry Hill Mall.

Rouse and Wells Fargo are both unaffiliated with PREIT, and the terms of the transactions with Rouse and Wells Fargo were determined through arm's length negotiations. A special committee of PREIT's Board of Trustees comprised of all five of its independent trustees was formed to consider the fairness of the New Castle Associates contribution transaction (including the relevant elements of the Rouse transaction), and the special committee approved those transactions.

Each of Moorestown Mall, The Gallery at Market East, Exton Square Mall and Cherry Hill Mall was operated by Rouse as a retail mall, and PREIT and New Castle Associates intend to continue to operate these properties as retail malls. The following chart shows information related to each of these malls:

Copies of the principal agreements relating to the transactions described in this report are attached hereto and incorporated herein by reference. The description contained herein of those agreements does not purport to be complete and is qualified in its entirety by reference to the provisions of those agreements.

This report contains certain "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934 and the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and other matters that are not historical facts. These forward-looking statements reflect PREIT's current views about future events and are subject to risks, uncertainties, assumptions and changes in circumstances that may cause future events, achievements or results to differ materially from those expressed by the forward-looking statements. In particular, PREIT may not be able to consummate the sale of its multifamily portfolio or the acquisition of Echelon Mall and Plymouth Meeting Mall from the Rouse Company on previously announced terms, on otherwise favorable terms to PREIT, or at all. If such transactions are consummated, PREIT's actual results may differ significantly from those expressed in any forward-looking statement. If PREIT is unable to consummate the sale of the multifamily portfolio, it will be unable to use the proceeds from such sale to repay the Acquisition Credit Facility obtained in connection with the acquisitions from the Rouse Company. Certain factors that could cause PREIT not to consummate such transactions or could cause PREIT's actual results to differ materially from expected results include, without limitation, the satisfaction of closing conditions applicable to such transactions (some of which are beyond PREIT's control); and other economic, business or competitive factors. In addition, PREIT's business is subject to uncertainties regarding the revenues, operating expenses, leasing activities, occupancy rates, and other competitive factors relating to PREIT's portfolio and the properties proposed to be acquired, and changes in local market conditions as well as general economic, financial and political conditions, including the possibility of outbreak or escalation of war or terrorist attacks, any of which may cause future events, achievements or results to differ materially from those expressed by the forward-looking statements. PREIT does not intend to and disclaims any duty or obligation to update or revise any forward-looking statements or industry information set forth in this report to reflect new information, future events or otherwise.

FIRST AMENDMENT TO AGREEMENT OF PURCHASE AND SALE
PLYMOUTH MEETING MALL

THIS FIRST AMENDMENT TO AGREEMENT OF PURCHASE AND SALE ("Amendment") is made and entered into as of the 28th day of April, 2003, by and between PLYMOUTH MEETING PROPERTY, LLC, a Delaware limited liability company ("Seller"), and PR PLYMOUTH MEETING LIMITED PARTNERSHIP, a Pennsylvania limited partnership ("Buyer").

W I T N E S S E T H:

WHEREAS, Seller and Buyer are parties to an Agreement of Purchase and Sale (the "Original Agreement") dated as of March 7, 2003 pursuant to which Seller has agreed to sell and Buyer has agreed to buy: certain leasehold and fee interests, buildings and improvements located in Plymouth Township, Montgomery County, Pennsylvania and forming a part of Plymouth Meeting Mall, as more fully described in, and pursuant to the terms and conditions of, the Original Agreement; and

WHEREAS, Seller and Buyer desire to amend the Original Agreement pursuant to the terms of this Amendment.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Seller and Buyer agree as follows:

1. Defined Terms. Uppercase and defined terms, which are not defined in this Amendment, shall have the meaning ascribed to such terms in the Original Agreement. References to Articles and/or Sections shall correspond to Articles and Sections in the Original Agreement. Any reference in this Amendment to the Agreement shall mean the Original Agreement as modified by this Amendment.

2. Satisfaction of certain conditions. Buyer hereby acknowledges that the contingencies described in sections 7.2 and 7.3 have been satisfied and it no longer has any rights to terminate the Agreement based on those sections.

3. Alternate Agreement. Subparagraph (c) of section 3.5 shall be amended by deleting the words "March 20, 2003" and substituting in their place the words "May 23, 2003."

ARTICLE IV
FAILURE TO CLOSE

4.1 Liquidated Damages.

Accordingly, Buyer and Seller agree that the amount of "Liquidated Damages" as used herein shall equal Six Million Dollars ($6,000,000.00). The parties expressly agree that the Liquidated Damages were determined by the parties after negotiation, with both side represented by counsel, and that such damages are not intended as a penalty but are fairly related to the damage that the non defaulting party would suffer from the other party's breach of this Agreement.

4.2 Buyer's Default.

If Seller has complied with all of the covenants and conditions contained herein and is ready, willing and able to sell and transfer the Property Assets to Buyer in accordance with this Agreement and Buyer for any reason fails to consummate this Agreement in breach of its obligations to do so, then the parties agree that Seller may, by written notice to Buyer, as its sole remedy (i) terminate this Agreement and recover from Buyer as liquidated damages an amount equal to the Liquidated Damages, together with attorney's fees and court costs, if any, incurred by Seller in obtaining payment of the Liquidated Damages, or (ii) seek specific performance in which event Seller shall be entitled to recover from Buyer any attorney's fees and court costs incurred in seeking such remedy, provided that if Seller is unable to obtain the remedy of specific performance Seller shall not have waived its right to the Liquidated Damages by electing to sue for Specific Performance. If Seller receives the Deposit, such amount shall be credited against the Liquidated Damages.

4.3 Seller's Default.

If Buyer has complied with all of the covenants and conditions contained. herein and is ready, willing and able to pay the Purchas Price to Seller and consummate the transactions contemplated hereunder in accordance with this Agreement and Seller for any reason fails to consummate this Agreement in breach of its obligations to do so, Buyer may as its sole remedy either (i) terminate this Agreement whereupon Buyer may recover from Seller as liquidated damages an amount equal to the Liquidated Damages together with attorney's fees and court costs, if any, incurred by Buyer in obtaining payment of the Liquidated Damages, or (ii) seek specific performance of the Agreement in which event Buyer shall be entitled to receive from Seller any attorney's fees and court costs incurred in seeking such remedy, provided that if Buyer is unable to obtain the remedy of specific performance Buyer shall not have waived its right to the Liquidated Damages by electing to sue for specific performance.

4.4 Disposition of Deposit as the Result of and Lack of Satisfaction of Conditions.

If Seller terminates this Agreement as a result of the lack of satisfaction of any one or more of the conditions to Seller's obligations set forth in Section 8.1 or elsewhere in this Agreement and the lack of satisfaction of a condition is not related to Buyer's or Buyer's Affiliates' default hereunder or under the Contract between Echelon Mall Joint Venture and Echelon Acquisition LLC and PR Echelon Limited Partnership dated March 7, 2003 (as amended contemporaneously herewith, the "Echelon Contract"), or Buyer terminates this Agreement as a result of the lack of satisfaction of any one or more of the conditions to Buyer's obligations set forth in Section 8.2 or elsewhere in this Agreement, and the lack of satisfaction of a condition is not related to Buyer's breach or default hereunder or under the Echelon Contract, then the Deposit shall be promptly returned to Buyer.

4.5 Cross Default.

The parties agree that a breach by a party of the Echelon Contract shall also be a breach by such party of this Agreement.

5. Closing Date. Section 5.1 shall be amended by deleting the words "April 24" and substituting the words "May 30." In addition, both parties each shall have the right to extend Closing for a period not to exceed ten (10) business days provided, however, as a condition to either parties' right to postpone the Closing, (a) the Alternate Agreement and Leasing Agreement shall have been agreed to in final form and attached to the Agreement by amendment, and (b) the party extending Closing also shall extend the Closing under the Echelon Contract for the same number of days.

6. Mutual Representations and Warranties. Seller and Buyer represent and warrant to each other respectively that they have the requisite power and authority to enter into this Amendment; that all necessary and appropriate approvals, authorizations and other steps have been taken to effect the legality of this Amendment; that the signatories executiexecuting this Amendment on behalf of Seller and Buyer have been duly authorized and empowered to execute this Amendment on behalf of Seller and Buyer, respectively; and that this Amendment is valid and shall be binding upon and enforceable against Seller and Buyer and their respective successors and assigns and shall inure to the benefit of Seller and Buyer and their respective successors and assigns.

7. Final Agreement. This Amendment and the Original Agreement cover in full, each and every final agreement of every kind or nature whatsoever between Seller and Buyer concerning the Property Assets and all preliminary negotiations and agreements whatsoever of every kind or nature are merged in this Amendment and the Original Agreement. This Amendment and the Original Agreement cannot be

- 3 -

changed or modified in any manner other than by written amendment or modification executed by Seller and Buyer. Except as expressly provided for herein or where the context requires to conform the terms and conditions of the Original Agreement to the above, the terms and conditions of the Original Agreement shall remain unmodified and are hereby ratified and confirmed.

8. Counterparts. This Amendment may be executed simultaneously or in two (2) or more counterparts, each of which shall be deemed an original but which together shall constitute one and the same instrument.

IN WITNESS WHEREOF the parties hereto have executed this Amendment as of the date first above written, but intended to be effective as of the Effective Date.

A party may not exercise its 10 business day extension right unless such party also extends Closing under the Plymouth Contract for the same number of days. Should Closing occur after May 30, 2003 for any reason other than Buyer exercising its extension right, the Purchase Price shall be reduced in accordance with Schedule 5.1 of the Original Agreement.

However, if a Sears Building Agreement is not so executed, Seller may satisfy the condition set forth in Section 8.2(a)(xi) of the Agreement in the manner provided therein.

6. Mutual Representations and Warranties. Seller and Buyer represent and warrant to each other respectively that they have the requisite power and authority to enter into this Amendment; that all necessary and appropriate approvals, authorizations and other steps have been taken to effect the legality of this Amendment; that the signatories executing this Amendment on behalf of Seller and Buyer have been duly authorized and empowered to execute this Amendment on behalf of Seller and Buyer, respectively; and that this Amendment is valid and shall be binding upon and enforceable against Seller and Buyer and their respective successors and assigns and shall inure to the benefit of Seller and Buyer and their respective successors and assigns.

THIS CONTRIBUTION AGREEMENT (this "Agreement") is made as of the 22nd day of April, 2003, by and among PAN AMERICAN ASSOCIATES, a Pennsylvania limited partnership ("Pan American"); THE REVOCABLE TRUST OF ALBERT MARTA (the "Marta Entity"), and IVYRIDGE INVESTMENT CORP., a Delaware corporation (collectively the "Limited Partners" and together with Pan American, the "Contributors," and, each, a "Contributor"); PENNSYLVANIA REAL ESTATE INVESTMENT TRUST, an unincorporated association in business trust form created under Pennsylvania law pursuant to a Trust Agreement dated December 27, 1960, as last amended and restated on December 16, 1997 ("PREIT"); and PREIT ASSOCIATES, L.P., a Delaware limited partnership (the "UPREIT") and BARBARA M. DiFONZO and LAUREN M. DeMICHIEL (collectively, the "Marta Individuals").

Background

The Contributors represent 77.5% of the partnership interests in New Castle Associates, a Pennsylvania limited partnership ("New Castle") formed pursuant to a limited partnership agreement dated January 1, 1978, as last amended September 10, 2001 (the "Existing New Castle Partnership Agreement") and the Marta Individuals are the general partners of Marta Investments, L.P. ("MI"), the remaining partner of New Castle. New Castle is the owner of a retail shopping center project in New Castle, Delaware, known as the Christiana Mall, and approximately eight (8) acres of adjoining ground (the "Land") on which a portion of a golf course is located (collectively, the "New Castle Property"). Pan American is the sole general partner of New Castle, and the Limited Partners are all of the limited partners of New Castle.

The UPREIT has been formed by PREIT and PREIT Property Trust, a Pennsylvania business trust ("PREIT Subsidiary"), pursuant to the terms of an Agreement of Limited Partnership of PREIT Associates, L.P. dated as of June 30, 1997, as amended and restated by a First Amended and Restated Agreement of Limited Partnership dated September 30, 1997 and as last amended on October 13, 1998 ( as the same may be amended from time to time in accordance with the provisions thereof, the "UPREIT Partnership Agreement").

-3-

New Castle has entered into an agreement (the "Christiana Agreement") with the Rouse Company and/or its affiliates ("Rouse Parties") wherein, among other things, the New Castle Property (including the Christiana Mall and the adjoining land referred to above as well as certain corporate stock) will be transferred to the Rouse Parties, under and subject to the existing secured indebtedness thereon and associated rights held by the Equitable Life Assurance Society of the United States ("Equitable"), including but not limited to the right and option of Equitable to be admitted as a fifty percent (50%) partner in New Castle Associates (such indebtedness and rights being hereinafter collectively referred to as the "Equitable Lien" and the loan documents relating to the Equitable Lien being collectively referred to as the "Loan Documents"), but free of all other mortgage indebtedness.

The UPREIT or its Affiliates have entered into various agreements with the Rouse Parties (the "Mall Agreements") for the acquisition of fee title to, or all the direct and indirect beneficial ownership interests in, the six mall properties (the "Mall Properties") known as the Cherry Hill Mall, Moorestown Mall and Echelon Mall (in New Jersey) and the Plymouth Meeting Mall, Exton Mall and Gallery I (in Pennsylvania).

The UPREIT will, as set forth herein, designate that New Castle accept an assignment and assumption of those Mall Agreements which pertain to not more than two (2) of the Mall Properties (the "Replacement Agreements", and the property covered thereunder being referred to collectively as the "Replacement Property", provided that the Replacement Property will include neither the Gallery I nor the Echelon Mall, and provided that the secured indebtedness against the Replacement Property is at least $120 Million). Pursuant to such assignment and assumption, it is anticipated that, either directly or through a qualified intermediary, the New Castle Property will be exchanged for the Replacement Property in a transaction qualifying (as to New Castle) as a tax-free exchange under Section 1031 of the Internal Revenue Code. As used herein, the term "Exchange Agreements" means, collectively, the Christiana Agreement and the Replacement Agreements.

-4-

Subject to the terms and conditions of this Agreement, the parties intend that, upon the conveyance to the Rouse Parties or their designees of the New Castle Property pursuant to the Christiana Agreement, the Contributors (or certain of the Contributors) will contribute to the UPREIT, in exchange for Class A or Class B limited partner interests in the UPREIT (as applicable, "Units"), portions of their partnership interests in New Castle, and thereupon a designee of the UPREIT shall become the sole general partner of New Castle and the partnership agreement of New Castle will be amended (the "Amended and Restated New Castle Partnership Agreement"), and thereafter, New Castle will acquire the Replacement Property. The interests of Contributors in New Castle to be contributed initially to the UPREIT are herein referred to as the "Transferred Interests", and the interests of the Contributors which will be initially retained by Contributors are herein referred to as the "Retained Interests".

NOW, THEREFORE, in consideration of the foregoing and mutual representations, warranties, covenants and agreements contained herein, the parties hereto, intending to be legally bound, hereby agree as follows:

SECTION 1. NEW CASTLE EQUITY VALUE; MISCELLANEOUS DEFINITIONS

1.1 New Castle Equity Value. As used in this Agreement, the "New Castle Equity Value" means the stipulated amount of Forty Four Million Dollars ($44,000,000), plus or minus the Net Adjustment Amount determined at Closing pursuant to Section 8.3 hereof, and as adjusted pursuant to Section 3.1(c) hereof or as elsewhere expressly provided in this Agreement. The parties acknowledge that, subject to the aforesaid adjustments, $40,000,000 of the New Castle Equity Value is allocable to the Christiana Mall portion of the New Castle Property, and $4,000,000 of the New Castle Equity Value is allocable to the Land portion of the New Castle Property.

1.2 Miscellaneous Definitions.

(a) Affiliate. "Affiliate" means, with respect to any specified Person, any other Person that directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with such specified Person.

(b) Authorizations. "Authorizations" means all licenses, permits, approvals, consents and authorizations required by any governmental or quasi-governmental agency, body, department, commission, board, bureau, instrumentality, officer, or other Person or entity with respect to the business, assets or affairs of a party.

-5-

(c) Contracts. "Contracts" means any contractual obligations, commitments, undertaking or arrangements to which a party is bound, whether oral or in writing, other than occupancy leases of the New Castle Property, including without limitation (1) Contracts with service providers relating to the assets of New Castle, and (2) Contracts with municipal or governmental authorities.

(d) Contributor Disclosure Exhibit. "Contributor Disclosure Exhibit" means Schedule 1.2 (d) hereto, which sets forth certain qualifications and exceptions to the representations, warranties and other information provided by the Contributors in this Agreement.

(e) Laws. "Laws" means any applicable governmental laws, statutes, ordinances, resolutions, rules, codes, regulations, orders or determinations of any federal, state, county, municipal or other government or governmental or quasi-governmental agency, department, commission, board, bureau, officer or instrumentality, relating to a party, its partners, assets, rights and obligations.

(f) Person. "Person" means any individual, partnership, limited partnership, trust, estate, incorporated or unincorporated association, limited liability company, limited liability partnership, or other entity.

(g) Taxes. "Taxes" means any income, franchise, sales, use, social security, unemployment compensation or other taxes, imposts or impositions payable by an entity to any federal, state or local collecting authority, other than ad valorem real estate taxes.

SECTION 2. CONTRIBUTIONS AND CALL.

2.1 Transferred and Retained Interests. The Transferred Interests and Retained Interests consist of specified percentages of the existing partnership interests of each of the Contributors in New Castle, and are described on Schedule 2.1 (a) hereto. Notwithstanding the foregoing, the Contributors shall have the right, upon notice to the UPREIT given prior to Closing, to adjust the Transferred Interests as among the Contributors, so long as the total of the Transferred Interests equals 49% of all partnership interests in New Castle, and the total of the Retained Interests equals the balance of Interests held by the Contributors, and further provided, that any Marta Entity shall be a Transferred Interest unless such entity agrees to be a Retained Interest.

-6-

(a) Notwithstanding the foregoing, it is acknowledged that, in connection with its admission to New Castle, the UPREIT intends to make a capital contribution to New Castle as may be necessary (1) to consummate the acquisition of the Replacement Property in a transaction qualifying (as to New Castle) as a tax-free exchange under Section 1031 of the Internal Revenue Code (the "UPREIT Added-Equity Contribution"), and (2) subject to the UPREIT's approval of the amount thereof and to the condition that no cash distributions shall be made to the partners of New Castle prior to Closing, to cover any anticipated shortfall (the "Cash Closing Shortfall") in the cash position of New Castle in order to effectuate closing under this Agreement and the Christiana Agreement (the "Cash Closing Shortfall Contribution"). If either or both of such capital contributions are made, the Amended and Restated New Castle Partnership Agreement shall reflect an increase in the interest of the UPREIT, and a corresponding decrease in the Retained Interests (to be made pro-rata among the holders of such Retained Interests), based upon the relative aggregate amount of such contributions as compared to the New Castle Equity Value, it being further understood that the New Castle Equity Value shall neither increase nor decrease by reason of the Upreit Added-Equity Contribution, but shall be reduced (as more particularly set forth in this Agreement) by any Cash Closing Shortfall Contribution. The New Castle Equity Value shall also be adjusted by the Net Adjustment Amount as set forth in Section 8.3 hereof.

2.2 Contributions at Closing. Subject to the terms and conditions of this Agreement, at the Closing (as defined in Section 7.1), the Contributors (or such of the Contributors who are designated to make such contribution pursuant to the terms of this Agreement) shall contribute to the UPREIT, and the UPREIT shall acquire from such Contributors, free and clear of all liens, claims and encumbrances of any type or nature, the Transferred Interests and all benefits and advantages to be derived therefrom, including, without limitation, all right, title and interest associated with the Transferred Interests in and to
(i) the capital accounts of such Contributors, (ii) distributions by New Castle, and (iii) allocable shares with respect to profits and losses of New Castle.

-7-

2.3 Option to Acquire Retained Interests. Pursuant to the terms of a separate Put and Call Option Agreement in the form set forth on Schedule 2.3 hereto to be entered into at Closing by and among the UPREIT, the Contributors (or such of Contributors who retain interests in New Castle following Closing hereunder) and the general partner of New Castle (the "Second Acquisition Agreement"), and as more particularly set forth therein:

(a) Each of the Contributors who has a Retained Interest has granted to the UPREIT the right and option (the "Call"), during a specified period of time, to acquire all of its Retained Interests, free and clear of all liens, claims and encumbrances of any type or nature, in exchange for a specified number of Units; and

(b) If the Call has not been exercised within the time allowed therefor, certain rights shall accrue in favor of the Contributors during a subsequent period of time to require the UPREIT to acquire all or some of the Retained Interests, free and clear of all liens and encumbrances of any type or nature, in exchange for a specified number of Units (the "Put").

2.4 Second Closing. The time at which the Retained Interests are required to be contributed by Contributors to the UPREIT pursuant to the Call or the Put is herein referred to as the "Second Closing".

SECTION 3. CONSIDERATION.

3.1 Unit Calculation. At the Closing, in consideration for the contributions of the Transferred Interests described in Section 2, and subject to the terms and conditions of this Agreement, the UPREIT shall issue to each of the transferring Contributors the number of Class A or Class B Units of the UPREIT computed as follows:

(a) A Contributor shall receive either Class A Units or Class B Units. Pan American shall receive Class A Units, and all other Contributors shall receive Class B Units. The Number of Units to be issued to a Contributor shall be equal to the product of (A) the percentage interest in New Castle represented by the Transferred Interest of such Contributor (i.e., the aggregate percentage of total partnership interests represented by such Transferred Interest), and (B) the quotient obtained by dividing the New Castle Equity Value by the average closing price of a share of the publicly traded beneficial interests of PREIT during the ten (10) trading day period immediately preceding Closing (the "Average Closing Price"); provided that the number of Units so derived shall be rounded to the nearest integer (0.5 rounded down). For example, if a Contributor's Transferred Interest was a 10% interest in New Castle, if the average closing price of a share of PREIT was $25, and if the New Castle Equity Value was $44 Million, then the Contributor would be entitled to 176,000 Units. If the UPREIT invests in New Castle as provided in Section 2.1, the Unit calculation specified hereunder shall be made without regard thereto except for a Cash Closing Shortfall Contribution.

-8-

(b) Notwithstanding anything to the contrary set forth herein, the UPREIT shall have the right and option to deliver to any Contributor who is not an "accredited investor," as such term is defined under Regulation D promulgated pursuant to the Securities Act of 1933, as amended (the "Act"), in lieu of any Units which would otherwise be issuable to such Contributor pursuant to Section 3.1(a) of this Agreement, an amount of cash equal to the product of (i) the number of Units otherwise issuable to such Contributor pursuant to Schedule 3(a) of this Agreement and (ii) the Average Closing Price.

(c) If, after the date hereof, there shall occur any recapitalization, unit division, reverse division, unit re-issuance or any other transaction involving the UPREIT or PREIT whereby a Class A Unit or a Class B Unit of the UPREIT (as it exists on the date hereof) shall be reconstituted as a different number of Class A Units or Class B Units, respectively, and/or as a specified number of units having a different class or designation (in each case subject to the necessary requirements specified in the UPREIT Partnership Agreement), or if there shall occur any merger, consolidation or other transaction involving the UPREIT and/or PREIT whereby specified interests or units are substituted for a Class A Unit or a Class B Unit (or for the reconstituted Units determined as aforesaid), then for purposes of computing the number of Units to be issued under this Agreement, such reconstituted or substituted number of Class A Units, Class B Units and/or specified other Units or interests shall be substituted for each Class A Unit or Class B Unit, as the case may be, otherwise applicable hereunder. Any such substitution shall be accomplished in a manner that neither increases nor decreases the value of the Units to be received by the Contributors as compared to other holders of Class A or Class B Units under the UPREIT Partnership Agreement.

(d) Notwithstanding the foregoing or anything to the contrary in this Agreement or the UPREIT Partnership Agreement (including any applicable time limitations on transfers of Units), solely as to any Transferred Interests of any of the Marta Entities, PREIT and the UPREIT acknowledge and agree as follows:

-9-

(i) Each Marta Entity has advised PREIT and the UPREIT that, pursuant to applicable law or its governing documents, it may desire to transfer all or some of the Units that it receives at the Closing to its partners, beneficiaries or other equity holders (as the case may be, the "Transferees") in accordance with their respective interests therein. Accordingly, each Marta Entity hereby reserves the right, upon written notice to PREIT and the UPREIT, to transfer such Units to its Transferees, provided, in each case, that (A) such transfer is made to the Transferees pro rata in accordance with their respective interests in the transferring Marta Entity; (B) such Transferees do not pay any consideration to the transferring Marta Entity(ies) for such Units; (C) each Transferee certifies in writing to PREIT and the UPREIT that such Transferee is accepting the Units for his, her or its own account, not as a nominee or agent for any other Person, solely for investment purposes, and without a view to resale or other distribution within the meaning of the 1933 Act, and the rules and regulations thereunder, and that such Transferee will not distribute any of such Units in violation of the 1933 Act or any applicable state securities law; (D) each Transferee executes and delivers to PREIT and the UPREIT an agreement whereby such Transferee shall assume all of the obligations of the transferring Marta Entity under the UPREIT Partnership Agreement with respect to the Units being transferred to such Transferee; and (E) each transferring Marta Entity and each Transferee executes and delivers to PREIT and the UPREIT such other transfer documentation as either may reasonably request. PREIT and the UPREIT hereby consent to any transfers of Units by a Marta Entity effected in accordance with this clause (i), and agree to take such actions as shall be reasonably necessary to effect each such transfer.

-10-

(ii) If any or all of the Marta Entities (or any of their Transferees pursuant to transfers effected in accordance with clause (i) above) shall exercise the right to tender Units for redemption under section 9.5 of the UPREIT Partnership Agreement, and if such tender shall occur during the period beginning on the first business day following the Closing and continuing for five (5) business days thereafter, then PREIT, as general partner of the UPREIT, shall waive its right to require that such tendered Units be redeemed for shares of beneficial interest in PREIT in lieu of cash; provided that such waiver shall extend only to fifty percent (50%) of the aggregate number of Units issued at Closing to the Marta Entities, so that the Marta Entities (or their Transferees) will be entitled to receive cash for fifty percent (50%) of their Units which are redeemed within the aforesaid period.

SECTION 4. REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTORS.

4.1 As to the Contributors and Marta Individuals. For purposes hereof, the term "Contributor Entity" means the legal entity (i.e., limited partnership, corporation, estate or trust) which comprises a Contributor. Each Contributor and Marta Individual (who shall be jointly referred to as a "Contributor" for purposes of this Section 4 only) severally, but not jointly, hereby represents and warrants to PREIT and the UPREIT as follows:

(a) Organization. If the Contributor is a Contributor Entity, such Contributor Entity is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has all power to carry on its business as presently conducted, to own its interest in New Castle and to exercise all rights attributable to such interest. It is duly qualified to do business as a foreign entity and is in good standing under the laws of each jurisdiction in which its ownership of or other interest in assets or properties or the nature of its activities requires such qualification except where the failure to be so qualified would not have a material adverse effect on the condition (financial or otherwise), assets, results of operations or business of such Contributor Entity (a "Material Adverse Effect").

-11-

(b) Power and Authority. It has all requisite power and authority to execute, deliver and perform its obligations under this Agreement and under the other agreements and documents required to be delivered by it prior to or at the Closing (collectively, and together with all documents and agreements required to be delivered by the other Contributors on or prior to the Second Closing, the "Contributor Transaction Documents"). The execution, delivery and performance by it of this Agreement and the other Contributor Transaction Documents to which it is a party have been duly authorized by all necessary action on the part of such Contributor or Contributor Entity. This Agreement has been duly and validly executed and delivered by it and constitutes a legal, valid and binding obligation of such Contributor enforceable against it in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally or by general equitable principles. When executed and delivered as contemplated herein, each of the other Contributor Transaction Documents to which such Contributor is a party shall, assuming due authorization, execution and delivery thereof by the other parties thereto, constitute a legal, valid and binding obligation of such Contributor enforceable against it in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally or by general equitable principles.

(c) No Conflicts. The execution and delivery by it of this Agreement does not, and the performance by it of all of the Contributor Transaction Documents will not (with or without the passage of time or the giving of notice), directly or indirectly:

(i) contravene, violate or conflict with (A) its articles of incorporation, bylaws, partnership agreement or other organizational documents, as the case may be, or (B) any Law applicable to such Contributor, or by or to which any assets or properties of such Contributor is bound or subject;

(ii) violate or conflict with, result in a breach of, constitute a default or otherwise cause any loss of benefit under, or give to others any rights (including rights of termination, amendment, foreclosure, cancellation or acceleration) in or with respect to, any Authorization or Contract to which such Contributor is a party or by which such Contributor or any assets or properties thereof is bound or affected; or

-12-

(iii) result in, require or permit the creation or imposition of any lien or encumbrance upon or with respect to such Contributor, the Transferred Interests, the Retained Interests, or any of such Contributor's other assets or properties.

(d) Authorizations. The execution and delivery by it of this Agreement does not, and the execution and delivery by such Contributor of the other Contributor Transaction Documents, and the performance by such Contributor of this Agreement and all of the Contributor Transaction Documents will not, require such Contributor to obtain any authorization of, or to make any filing, registration or declaration with or notification to, any court, government or governmental agency or instrumentality (federal, state, local or foreign) or to obtain the consent, waiver or approval of, or give any notice to, any other Person.

(e) Proceedings. There are no claims, actions, suits, proceedings or investigations pending or, to the knowledge of such Contributor, threatened or contemplated, involving or affecting it or any of its assets or properties or to its knowledge any of its directors, officers, partners, trustees or shareholders, that question any of the transactions contemplated by this Agreement or other Contributor Transaction Documents, or which, if adversely determined, would have a Material Adverse Effect or could materially and adversely affect such Contributor's ability to enter into or perform its obligations under this Agreement.

(f) Orders. No officer, director, partner, or, to the knowledge of such Contributor, employee or shareholder of such Contributor is subject to any order that prohibits such officer, director, partner, shareholder or employee from engaging in or continuing any conduct, activity or practice relating to its business with respect to New Castle or the New Castle Property.

(g) The Transferred and Retained Interests.

(i) No person or entity has any partnership or other interest in New Castle or any right to receive any distributions from New Castle or be allocated any profits or losses of New Castle, other than the Contributors and
MI. Such Contributor owns, beneficially and of record, the portion of the Transferred Interests and Retained Interests described in Schedule 2.1(a) hereto, free and clear of all liens, pledges and encumbrances of any type or nature, other than the lien of Section 6324 of the Internal Revenue Code of 1986.

-13-

(ii) Except for this Agreement or for the rights of Equitable, Contributor has no knowledge of any rights, subscriptions, warrants, options, rights of first refusal, conversion rights or agreements of any kind outstanding to purchase or to otherwise acquire any partnership interest or other securities or obligations of any kind convertible into any partnership interest or other securities or any participation interests of any kind in New Castle or the New Castle Property.

(h) Brokers. No Person acting on behalf of such Contributor or any of their respective affiliates or under the authority of any of the foregoing is or will be entitled to any brokers' or finders' fee or any other commission or similar fee, directly or indirectly, from any of such parties in connection with any of the transactions contemplated by this Agreement. In such connection, however, the parties acknowledge that a brokerage commission of $2,000,000 will be due by reason of the closing under the Christiana Agreement by New Castle to Preit-Rubin, Inc. or an affiliated entity, pursuant to Section 3.5 of the existing management agreement for the New Castle Property, which brokerage commission is to be paid by New Castle to Preit-Rubin, Inc. or an affiliated entity at or prior to such closing.

(i) Accurate Disclosure. All documents and other papers delivered by or on behalf of such Contributor in connection with the transactions contemplated by this Agreement are accurate and complete in all material respects.

(j) Investment Representations.

(i) Contributor acknowledges that the Units to be issued pursuant to Section 3 and Schedule 2(a) hereto or pursuant to the Second Acquisition Agreement will not be registered under the 1933 Act on the grounds that the issuance of such units is exempt from registration pursuant to Section 4(2) of the 1933 Act and/or Regulation D promulgated under the 1933 Act, and that the reliance of the UPREIT on such exemptions is predicated in part on the Contributors' representations, warranties and acknowledgements set forth in this section.

-14-

SECTION 8. PRE-CLOSING DISTRIBUTIONS; CLOSING COSTS; NET DISTRIBUTION AMOUNT

8.1 Costs. The Contributors shall bear and be responsible for their respective costs in connection with the contributions contemplated by this Agreement, including counsel fees. New Castle shall bear and be responsible for New Castle's costs in connection with the transactions contemplated by the Exchange Agreements, including all applicable realty transfer taxes, counsel fees and brokerage fees; it being further understood that all such costs to be borne by New Castle shall be chargeable to the Contributors but shall not be a personal obligation of the Contributors and instead shall be encompassed within the Cash Closing Shortfall and shall reduce the New Castle Equity Value. The Contributors and New Castle shall bear no responsibility for PREIT or the UPREIT's costs in connection with the negotiation of, or due diligence with respect to, the Exchange Agreements, and no adjustment to the New Castle Equity Value will result therefrom. PREIT and the UPREIT agree that the Contributors shall have the right to structure, subject to PREIT'S reasonable approval, the form of the Exchange Agreement(s) to eliminate or minimize realty transfer taxation.

8.2 Cash. Pan American shall cause New Castle, prior to Closing, to apply cash and cash equivalents of New Castle (subject to any rights of Equitable), to closing-related expenses under this Agreement and the Christiana Agreement and it is not intended that the UPREIT will acquire any interest therein. The foregoing shall not apply to any reserves which are to be established or maintained pursuant to the terms of this Agreement. If any reserves or escrows are in effect at the time of Closing, any balances payable from them shall be distributed pro rata to the pre-Closing partners of New Castle.

8.3 Net Adjustment Amount. For purposes of this Agreement, the Net Adjustment Amount shall mean (i) the amount by which the purchase price for the New Castle Property to be paid by the Rouse Parties pursuant to the Christiana Agreement is increased or decreased as a result of the closing adjustments and apportionments to be made between New Castle and the Rouse Parties under the Christiana Agreement and (ii) if the UPREIT makes a capital contribution pursuant to Section 2.1 (a) of this Agreement for the purpose of paying the Cash Closing Shortfall (i.e., the excess of New Castle's required payments to Equitable, closing costs and related cash expenditures over its cash on hand), then the Net Adjustment Amount shall include a deduction in the amount of such Cash Closing Shortfall; if New Castle's assets other than those conveyed to Rouse exceed the cash required to Close, such excess shall be a positive Net Adjustment Amount. If accurate allocations for any of the items set forth herein cannot be made at Closing because current bills are not available or the like, then the parties shall make the allocations on the basis of the best available information, subject to final adjustment when reasonably practicable.

-34-

8.4 Damages. Any known Damages (as defined in Section 9.1 below) shall be calculated and shall increase the New Castle Equity Value if the net amount thereof is owed to Contributors, and shall decrease the New Castle Equity Value if the net amount thereof is owed to PREIT or the UPREIT.

8.5 Statement. At Closing, the parties shall execute and deliver to one another a statement detailing the Net Adjustment Amount and all relevant components and calculations thereof.

8.6 Transfer Taxes on Call or Put. Any realty transfer taxes which may be due by reason of the exercise of the Call or the Put or by reason of the transfers by the Contributors to the UPREIT of the Retained Interests or of the Transferred Interests or by reason of transfers of the Units from the UPREIT to the Contributors shall be the sole responsibility of the UPREIT.

8.7 Survival. The provisions of this Section 8 shall survive Closing and the Second Closing.

SECTION 9. INDEMNIFICATION

9.1 Indemnification by Pan American. Pan American shall and does hereby indemnify, defend and hold harmless PREIT and the UPREIT (collectively, "Preit Indemnitees") against and in respect of any and all losses, costs, expenses (including, without limitation reasonable attorneys' fees), claims, actions, damages, obligations, liabilities or diminutions in value (collectively, "Damages"), arising out of, based upon or otherwise in respect of: (a) any inaccuracy in or breach of any representation or warranty of Pan American or any other Contributor or Marta Individual made in or pursuant to this Agreement or failure of Pan American or such other Contributor or Marta Individual to perform any other obligation or undertaking hereunder; and (b) if closing occurs under the Christiana Agreement, any indemnification obligations, undertakings, agreements, warranties and/or representations of New Castle in favor of the Rouse Parties, their designees or successors, under or with respect to the Christiana Agreement, and (c) any act or omission of New Castle Associates or any of its partners, employees, agents or representatives in connection with the ownership or operation of the New Castle Property occurring at any time prior to the Closing or any liability or obligation incurred by New Castle at any time prior to the Closing, including without limitation any liability under or with respect to the Equitable Lien or the Equitable Loan Documents, provided that this indemnity right does not limit any claims that New Castle may otherwise possess against PREIT-Rubin, Inc., and its affiliates as manager of the New Castle Property. Notwithstanding the foregoing:

-35-

(a) The indemnification obligations of Pan American hereunder shall be fully enforceable against Pan American notwithstanding that the underlying claim or matter is the responsibility, as between Pan American and the other Contributors, of one or more of the other Contributors. The parties acknowledge that, pursuant to separate agreements between Pan American and the Contributors, the Contributors have agreed to certain contribution and sharing arrangements with respect to the indemnity obligations of Pan American; and it is further understood that (1) the UPREIT is not a beneficiary under such separate agreements, (2) such separate agreements shall not limit or restrict the rights of the UPREIT regarding the indemnification obligations of Pan American, and (3) the UPREIT consents to a pledge of and grant of a security interest in, the Units to be issued to the Contributors, in favor of Pan American, for the purpose of securing such contribution and sharing arrangements relating to the indemnity obligations of Pan American, provided that any proceeds or other realization by Pan American of such pledged Units shall be held and applied on account of Pan American's indemnity obligations; and

(b) Without limiting any other provisions, rights or remedies under this Agreement, the UPREIT shall have no recourse against any Contributor other than Pan American for the indemnification obligations of Pan American under this
Section 9.

-36-

9.2 Indemnification by PREIT. Subject to applicable limitations set forth in Section 5 above, the UPREIT and PREIT shall indemnify, defend and hold harmless each Contributor against and in respect of any and all Damages arising out of, based upon or otherwise in respect of; (a) any inaccuracy in or breach of any representation or warranty of PREIT or the UPREIT made in or pursuant to this Agreement; and (b) any breach or nonfulfillment of any covenant or obligation of PREIT or the UPREIT contained in this Agreement.

9.3 Limitation. No party may assert a claim for indemnification pursuant to this Section 9 unless the Closing has occurred under this Agreement.

9.4 Procedure For Indemnification - Third Party Claims.

(a) Within thirty days after receipt by an indemnified party of notice of the commencement of any proceeding against it to which the indemnification in this Section 9 relates, such indemnified party shall, if a claim is to be made against an indemnifying party under Section 9, give notice to the indemnifying party of the commencement of such proceeding, but the failure to so notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party, demonstrates that the defense of such proceeding is materially prejudiced by the indemnified party's failure to give such notice.

(b) If any proceeding referred to in paragraph (a) above is brought against an indemnified party and it gives notice to the indemnifying party of the commencement of such proceeding, the indemnifying party will be entitled to participate in such proceeding and, to the extent that it wishes (unless (i) the indemnifying party is also a party to such proceeding and the indemnified party

-37-

determines in good faith that joint representation would be inappropriate, or
(ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to defend such proceeding and provide indemnification with respect to such proceeding), to assume the defense of such proceeding with counsel reasonably satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under Section 9 for any fees of other counsel or any other expenses with respect to the defense of such proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such proceeding, other than reasonable costs of investigation. If the indemnifying party assumes the defense of a proceeding, (A) it will be conclusively established for purposes of this Agreement that the claims made in that proceeding are within the scope of and subject to indemnification; (B) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party's consent unless (l) there is no finding or admission of any violation of Law by the indemnified party (or any affiliate thereof) or any violation of the rights of any Person and no effect on any other claims that may be made against the indemnified party, and (2) the sole relief provided is monetary damages that are paid in full by the indemnifying party. The indemnified party will have no liability with respect to any compromise or settlement of the claims underlying such proceeding effected without its consent. If notice is given to an indemnifying party of the commencement of any proceeding and the indemnifying party does not, within ten days after the indemnified party's notice is given, give notice to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will be bound by any determination made in such proceeding or any compromise or settlement effected by the indemnified party.

(c) Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, with respect to those issues, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such proceeding, but the indemnifying party will not be bound by any determination of a proceeding so defended or any compromise or settlement effected without its consent.

-38-

9.5 Procedure for Indemnification - Other Claims. A claim for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought.

9.6 Distributions of Units by Contributors. Without limiting any other applicable restrictions or limitations on the transfer of Units, Pan American shall not distribute or otherwise transfer to any other Person Units issued to it pursuant to this Agreement unless such Person first executes and delivers to PREIT and the UPREIT an agreement, in form and substance reasonably satisfactory to PREIT and the UPREIT, by which such Person would join in and become a party to this Agreement for purposes of the indemnification provisions hereof.

9.7 Right of Set-Off. PREIT and the UPREIT shall have the right to set-off, against any Units which may be owed by PREIT or the UPREIT to Pan American or any distributions, rights or benefits with respect thereto, any amount owed to any Preit Indemnitee. To the extent that Pan American contests an indemnification claim of PREIT or the UPREIT that would be the basis for the exercise of a right to set off against any Units owed to Pan American, the UPREIT shall issue such Units and deposit them with an escrow agent reasonably satisfactory to the UPREIT and Pan American until the earlier to occur of (i) resolution of such dispute by a final nonappealable order of a court of competent jurisdiction or (ii) the mutual agreement of Pan American and the UPREIT that such units should be released from escrow.

9.8 Indemnification Payments. Pan American shall be entitled to use cash or Units to make indemnification payments hereunder. In the event Units are used, each such unit shall be valued based on the per share Value (as defined in the UPREIT Partnership Agreement) of a PREIT Share as of the date such unit is tendered to PREIT as an indemnification payment hereunder.

9.9 Survival. The rights and obligations of the parties set forth in this Section 9 shall survive the Closing and the Second Closing.

-39-

SECTION 10. TERMINATION AND ABANDONMENT.

10.1 Termination. This Agreement may be terminated and the transactions contemplated herein may be abandoned at any time prior to the Closing:

(i) by any party hereto, if the Closing has not occurred (other than through the failure of the party seeking to terminate this Agreement to comply fully with its obligations under this Agreement) on or before June 28, 2003, or such later date as the parties may mutually agree upon in writing;

(ii) by mutual consent of the UPREIT, PREIT and the Contributors;

(iii) by PREIT and the UPREIT, if any of the conditions in Section 7.2(a) have not been satisfied as of the Closing Date or if satisfaction of such a condition is or becomes impossible (other than through the failure of PREIT or the UPREIT to comply with its obligations under this Agreement) and PREIT and the UPREIT have not waived all such unsatisfied conditions before termination pursuant to this subparagraph (iii); or

(iv) by the Contributors if any of the conditions in Section 7.2(b) have not been satisfied as of the Closing Date or if satisfaction of such a condition is or becomes impossible (other than through the failure of any Contributor to comply with its obligations hereunder) and the Contributors have not waived all such unsatisfied conditions before termination pursuant to this subparagraph (iv).

10.2 Procedure for Termination; Effect of Termination. A party terminating this Agreement pursuant to this Section 10 shall give written notice thereof to each other party hereto, whereupon this Agreement shall terminate and the transactions contemplated hereby shall be abandoned without further action by any party and all further obligations of the parties under this Agreement will terminate; provided, however, that if the reason for such termination is attributable to the willful failure of a party to perform its obligations hereunder, or a willful misrepresentation or breach of warranty, then such party shall reimburse to the other party its reasonable costs and expenses (including reasonable legal fees) in connection with this Agreement and the efforts to proceed to Closing hereunder.

-40-

SECTION 11. GENERAL PROVISIONS.

11.1 Survival of Representations and Warranties.

(a) All representations and warranties made by the parties in this Agreement and in the certificates, documents and other agreements delivered pursuant hereto shall survive the Closing. Anything in this Agreement to the contrary notwithstanding: (i) the representations and warranties of the Contributors and the right of the Preit Indemnitees to indemnification for breach thereof, shall not be affected by any investigation of the Contributors, New Castle, the New Castle Property or the Replacement Property made by PREIT, the UPREIT or their agents or representatives; and (ii) the representations and warranties of PREIT hereunder, and the right of the Contributors to indemnification for breach thereof, shall not be affected by any investigation of PREIT, the UPREIT or its affiliates made by the Contributors or their agents or representatives.

11.2 Costs and Expenses. Except as otherwise expressly provided herein, each party shall bear its own expenses in connection herewith.

CALL AND PUT OPTION AGREEMENT

THIS CALL AND PUT OPTION AGREEMENT (the "Agreement") is entered into as of the 28th day of April, 2003, by and among the parties listed on Schedule A hereto (referred to collectively as the "Class A Partners" and individually, a "Class A Partner"), and PREIT ASSOCIATES, L.P., a Delaware limited partnership (the "UPREIT"), with joinder by PR New Castle LLC, a Pennsylvania limited liability company (the "General Partner").

BACKGROUND:

The Class A Partners are all of the "Class A Limited Partners" of New Castle Associates, a Pennsylvania limited partnership (the "Partnership"). The UPREIT is the "Class B Limited Partner" of the Partnership. The General Partner is the sole general partner of the Partnership.

The Partnership is governed by an Amended and Restated Limited Partnership Agreement dated April 28, 2003 (the "Partnership Agreement"), a copy of which is attached hereto as Schedule B.

The Class A Partners hold limited partnership interests (a partnership interest being referred to separately as an "Interest" and multiple Interests being referred to as "Interests") as listed on Schedule A hereto. Such aggregate Interests of the Class A Partners are referred to herein as the "Retained Interests" and reflect a downward adjustment on account of the "UPREIT Special Capital Contribution," as that term is defined in the Partnership Agreement.

A portion of the Interests of the UPREIT and the General Partner were acquired from the Class A Partners pursuant to a Contribution Agreement (the "Contribution Agreement," a copy of which is attached hereto as Schedule C and which is incorporated herein by reference) dated April 22, 2003 by and among the Class A Partners, certain prior limited partners of the Partnership and certain general partners of prior limited partners of the Partnership, the UPREIT, and Pennsylvania Real Estate Investment Trust (the "Trust").


The Class A Partners and the UPREIT desire to provide a mechanism under which the UPREIT will have the right to acquire from the Class A Partners, and require the Class A Partners to contribute to the UPREIT, the Retained Interests pursuant to and in accordance with the terms and conditions of this Agreement (hereinafter defined and referred to as the "Call").

The Class A Partners and the UPREIT further desire to provide a mechanism under which, if the Call is not exercised, and following the expiration of a specified time period thereafter, the Class A Partners will have the right to contribute to, and require the UPREIT to acquire from the Class A Partners, all or some of the Retained Interests pursuant to and in accordance with the terms and conditions of this Agreement (hereinafter defined and referred to as the "Put").

NOW THEREFORE, in consideration of the mutual promises and agreements herein contained, and intending to be legally bound hereby, the parties hereto agree as follows:

1. Call and Put.

(a) Call Period. For the period commencing on the date (the "Call Commencement Date") which is one (1) year plus two (2) business days after the date hereof, and ending on the later of (x) the one hundred eightieth (180th) day after the Call Commencement Date, or (y) the tenth (10th) day following delivery of the Call Reminder Notice (such period being referred to as the "Call Period"), the UPREIT shall have the right (the "Call") to acquire from the Class A Partners, and upon exercise of the Call the Class A Partners shall be required to contribute to the UPREIT, all (and not less than all) of the Retained Interests for the Call Consideration (as hereinafter defined). The "Call Reminder Notice" means a notice from the Class A Partners to the UPREIT (given not earlier than 30 days prior to the expiration of the 180 day period following the Call Commencement Date) that such 180 day period is about to, or has, expired.

2

(b) Put Period. If the Call is not exercised within the Call Period, then for the period commencing on the date (the "Put Commencement Date") which is five (5) years after the date hereof, and ending on the later of (x) the one hundred eightieth (180th) day after the Put Commencement Date, or (y) the tenth
(10th) day following delivery of the Put Reminder Notice (such period being referred to as the "Put Period"), the Class A Partners (or such of the Class A Partners as may elect to exercise their rights under this subparagraph (b), without the requirement for all of the Class A Partners to do so) shall have the right (the "Put") to require the UPREIT to acquire, and upon exercise of the Put the Upreit shall be required to acquire by contribution from such Class A Partners, all of the Retained Interests owned by the exercising Class A Partners for the Put Consideration (as hereinafter defined) allocable to such Class A Partners. The "Put Reminder Notice" means a notice from the UPREIT to the Class A Partners (given not earlier than 30 days prior to the expiration of the 180 day period following the Put Commencement Date) that such 180 day period is about to, or has, expired.

(c) Closing; Consideration. The date on which the Call or the Put shall be consummated (i.e., when the Retained Interests shall be contributed to the UPREIT and the Consideration shall be paid), is herein referred to as the "Closing" or the "Closing Date". The applicable consideration to be paid at the Closing for the Call or the Put, as the case may be (i.e., the Call Consideration or the Put Consideration) is referred to herein as the "Consideration".

(d) Units. As used herein, a "Unit" means a Class A Unit or a Class B Unit of the UPREIT as defined and described in the first Amended and Restated Agreement of Limited Partnership of Preit Associates, L.P. dated September 30, 1997, as amended through October 13, 1998 (as amended, the "UPREIT Partnership Agreement," a copy of which is attached hereto as Schedule D).

3

(e) Call Consideration; UPREIT Units. The "Call Consideration" means, as to each of the separate Retained Interests of a Class A Partner, the specified number of Units allocable to such Class A Partner (i.e., Class A Units or Class B Units) as delineated on Schedule E attached hereto, subject to the adjustment (if any) set forth in subsection (g) below.

(f) Put Consideration. The Put Consideration means, with respect to a the Retained Interest of a particular Class A Partner who has exercised the Put, the specified number of Units allocable to such Class A Partner (i.e., Class A Units or Class B Units) as delineated on Schedule F attached hereto, subject to the adjustment (if any) set forth in subsection (g) below.

(g) Adjustment to Consideration. The Call Consideration or Put Consideration set forth above shall be adjusted as follows:

(i) If, after the date hereof, there shall occur any recapitalization, unit division, reverse division, unit re-issuance or any other transaction involving the UPREIT or the Trust whereby a Class A Unit or a Class B Unit (as it exists on the date hereof) shall be reconstituted as a different number of Class A Units or Class B Units, respectively, and/or as a specified number of units having a different class or designation (in each case subject to the necessary requirements specified in the UPREIT Partnership Agreement), or if there shall occur any merger, consolidation or other transaction involving the UPREIT and/or the Trust whereby specified interests or units are substituted for a Class A Unit or a Class B Unit (or for the reconstituted Units determined as aforesaid), then for purposes of computing the Consideration, such reconstituted or substituted number of Class A Units, Class B Units and/or specified other Units or interests shall be substituted for each Class A Unit or Class B Unit, as the case may be, otherwise constituting a part of the Consideration. Any such substitution shall be accomplished in a manner that neither increases nor decreases the value of the Units to be received by the Contributors as compared to other holders of Class A or Class B Units under the UPREIT Partnership Agreement.

4

(ii) Notwithstanding anything to the contrary set forth herein, as to any Class A Partner who is not an "accredited investor," as such term is defined under Regulation D promulgated pursuant to the 1933 Securities Act (the "Act"), in lieu of any Units which would otherwise be issuable to such Class A Partner pursuant to this Agreement, the Consideration shall, at the sole option and discretion of the UPREIT, be an amount of cash equal to the product of (i) the number of Units otherwise issuable to such Class A Partner and (ii) the Average Closing Price (as that term is defined in Section 3.1 (a) of the Contribution Agreement, calculated as of the relevant date of Closing for the Put or Call, as the case may be) attributable to the Units in question (i.e., the cash equivalent of such Units based upon the average closing price of a share of the publicly traded beneficial interests corresponding to the Units during the 10 day period preceding the Closing).

(iii) If applicable, a further adjustment shall be made to the Consideration to reflect any differences in distributions to the Class A Partners made under the Partnership Agreement as compared with distributions accrued or accruing with respect to the Units.

(iv) If at the time of Closing for the Put or Call there is any balance of Unpaid Preferred Return under the Partnership Agreement due to the Class A Partner whose interest is being acquired, the UPREIT shall deliver cash or Units having a fair market value equal to such Unpaid Preferred Return as additional consideration. If the UPREIT elects to deliver Units, they shall be valued at the mean of the high and low trading price on the day immediately prior to the date of payment. Upon receipt of the payment or transfer required herein, all of the Class A Partner's interest in the Unpaid Preferred Return shall be deemed transferred to the UPREIT.

5

(v) If, between the date hereof and the date of Closing for the Call or the Put, there have been any distributions under the Partnership Agreement of Net Capital Proceeds to a Class A Partner whose interest is being acquired, then the Consideration payable to such Class A Partner shall be reduced by the aggregate amount of such distributions. Such reduction shall be calculated by valuing the Units at the mean of the high and low trading price on the day immediately prior to the date of payment.

2. Exercise of Call or Put; Closing.

(a) Call Notice. If the UPREIT elects to exercise the Call, the UPREIT shall do so by providing the Class A Partners written notice of such desire at any time within the Call Period ("Call Notice"). If the Call Notice is given within the Call Period, the Class A Partners shall be required to contribute all of the Retained Interests to the UPREIT for the Consideration allocable to the Class A Partners, at the Closing.

(b) Put Notice. If one or more of the Class A Partners elect to exercise the Put, such Class A Partner(s) shall do so by providing the UPREIT with written notice of such desire at any time within the Put Period ("Put Notice"). If the Put Notice is given within the Put Period, the UPREIT shall be required to acquire all of the Retained Interests of all of the Class A Partners who have given the Put Notice, for the Consideration allocable to such Class A Partners, at the Closing.

(c) Closing Date. Following the delivery of the Call Notice, the Closing shall occur on the later to occur of (x) fifteen (15) days following the date of the Call Notice, or (y) the first business day following the next quarterly "ex-dividend" date for the common shares of beneficial interest of the Trust ("Trust Shares") following the giving of the Call Notice. If one or more Class A Partners shall deliver the Put Notice, there shall in all cases be only one Closing for all Retained Interests to be acquired pursuant to the Put; and therefore, unless otherwise agreed by all of the Class A Partners and the UPREIT, the Closing for the Put shall occur on the first business day following the next quarterly "ex-dividend" date for the Trust Shares following the expiration of the Call Period. Closing shall occur at the offices of the UPREIT, Philadelphia, Pennsylvania.

6

3. Closing Deliveries.

(a) Class A Partner Deliveries. At the Closing for the Put or Call, as the case may be, each Class A Partner who is required to contribute its interests to the UPREIT shall execute and deliver to the UPREIT:

(i) an absolute and unconditional assignment of its Retained Interest and all rights relating thereto, free and clear of all liens, claims and encumbrances of any type or nature, by documentation substantially similar to that utilized for the contribution of partnership interests under the Contribution Agreement,

(ii) certificates of good standing as of a current date for each such Class A Partner, certified by the Secretary of State or corresponding certifying authority,

(iii) Uniform Commercial Code financing statement searches from the secretaries of state in which each such Class A Partner maintains its place(s) of business, disclosing no grant of a security interest in the Retained Interests,

(iv) an opinion of counsel to each such Class A Partner in form and substance reasonably satisfactory to the UPREIT, relating to the authorization and enforceability of the documents and instruments executed and delivered by such Class A Partner,

(v) counterpart signature pages and/or related certificates to confirm such Class A Partner's agreement to become a limited partner in the UPREIT and to be bound by the UPREIT Partnership Agreement, as it may hereafter be amended through the date of Closing, including without limitation any amendment deemed necessary by the UPREIT to confirm and authorize the issuance of the Units (provided that no such future amendment shall materially impair the attributes of the Units as compared to the existing Units heretofore acquired by the Class A Partners in the UPREIT pursuant to the Contribution Agreement),

7

(vi) a written restatement, representation and warranty ("Updated Warranties") as to the truth and accuracy of all of the Basic Warranties (as defined in subsection (b) below) as of the Closing Date, which shall survive Closing, with the further understanding that any disclosed qualifications or exclusions to the Updated Warranties shall be known as "Warranty Exceptions" and shall be subject to the provisions of Section 7(a) below, and

(vii) such other documents and instruments as the UPREIT may reasonably request to effectuate or evidence the transactions contemplated under this Agreement.

(b) Basic Warranties. As used herein, the "Basic Warranties" means the warranties, certifications and representations, collectively, of the Class A Partners (therein designated as the "Contributors") under Section 4.1 of the Contribution Agreement. By way of clarification, the Updated Warranties shall include all matters set forth in Section 4.1 of the Contribution Agreement interpreted and construed as if the partnership interests therein referred to were the Retained Interests, as if the "Class A Partner Transaction Documents" referred to the documents and instruments to be executed and delivered by the Class A Partners at Closing under this Agreement, and as if all investment representations of the "Class A Partners" were made by the Class A Partners with respect to the Units to be issued pursuant to this Agreement.

(c) UPREIT Deliveries. At the Closing for the Put or Call, as the case may be, the UPREIT shall execute and deliver to each Class A Partner who is required to contribute its interests to the UPREIT:

8

(i) the Units to be delivered to such Class A Partner at Closing as set forth in this Agreement, or the cash amount in lieu thereof if Section 1(g)(ii) hereof is applicable;

(ii) any cash or Units required under Section 1(g)(iv);

(iii) a counterpart execution page of the documents referred to in
Section 3(a)(i) above;

(iv) an agreement whereby the UPREIT shall covenant that, as owner of the controlling interests in the general partner of New Castle, it shall not permit the Replacement Property (as defined in the Contribution Agreement) or the Retained Interests to be disposed of for a period of eight (8) years following the closing under the Contribution Agreement in such manner as to cause such Class A Partners to recognize taxable income and that any such disposition within such time period must be pursuant to a tax-free exchange under Section 1031 of the Internal Revenue Code or other tax-free disposition; provided that such disposition shall be permitted in a taxable transaction if such Class A Partners are paid an amount sufficient to reimburse them for any tax liability resulting from such transfer by reason of Section 704(c) of the Internal Revenue Code, together with all taxes payable on such reimbursement; and

(v) An agreement whereby the UPREIT will agree to cooperate in good faith with the Class A Partners whose interests are being acquired, in executing such documentation as may be required (such as limited guarantees of indebtedness by the Class A Partners) to avoid recognition of income or gain to such Class A Partners by reason of a constructive distribution to them under Section 752 of the Internal Revenue Code relating to relief from liabilities.

9

4. Failure to Purchase. The parties hereto acknowledge and agree that following the creation of a binding contract as a result of the delivery of the Call Notice or Put Notice in accordance with this Agreement, money damages alone would not be a sufficient remedy to a party for the failure of another party to consummate the transfer of the Retained Interests as set forth in this Agreement, and that irreparable harm would result to the impaired party if such obligations were not specifically enforced. Accordingly, all parties agree that their obligations hereunder shall be enforceable by a decree of specific performance issued by a court of competent jurisdiction, and that appropriate injunctive relief may be applied for and granted in connection therewith, in addition to the pursuit of applicable money damages.

5. Transfer Restrictions. The parties acknowledge and agree that the Retained Interests are subject to transfer restrictions as set forth in the Partnership Agreement. Without limiting such restrictions, between the date hereof and the expiration of the Put Period, except with the prior written consent of the UPREIT, no Class A Partner shall sell, assign, transfer or otherwise encumber all or any portion of the Retained Interests or any rights relating to the Retained Interests, whether voluntarily, by operation of law or otherwise, including without limitation a transfer by reason of any merger, division or consolidation, and any such sale, assignment, transfer or encumbrance shall be void. By its joinder herein, the General Partner acknowledges and consents to such restrictions and agrees that no such transfer shall be approved except with the consent of the UPREIT.

6. Representations and Warranties.

(a) Class A Partners. As a several and not a joint obligation, each of the Class A Partners hereby restates, certifies, represents and warrants to the UPREIT all of the Basic Warranties, which shall survive any Closing hereunder.

(b) UPREIT. The UPREIT hereby restates, certifies, represents and warrants to the Class A Partners the matters set forth in Section 5 of the Contribution Agreement as to its business affairs and status, which shall survive any Closing hereunder.

10

7. Indemnification.

(a) Class A Partners. Without limiting any indemnity or other obligation under the Contribution Agreement, each Class A Partner shall indemnify, defend and hold harmless the UPREIT and the Trust (collectively, "Preit Indemnitees") against and in respect of any and all losses, costs, expenses (including, without limitation, reasonable defense and attorneys' fees), claims, actions, damages, obligations, liabilities or diminutions in value (collectively, "Damages," and including any loss, liability or damages attributable to any Warranty Exceptions as defined in Section 3(a)(vi) above), arising out of, based upon or otherwise in respect of: (a) any inaccuracy in or breach of any representation or warranty of such Class A Partner made in or pursuant to this Agreement and/or to be made pursuant to the Put or the Call (including without limitation the Updated Warranties) and (b) any failure of such Class A Partner to perform any obligation relating to the Put or the Call.

(b) UPREIT. Without limiting any indemnity or other obligation under the Contribution Agreement, the UPREIT shall indemnify, defend and hold harmless each Class A Partner against and in respect of any and all Damages arising out of, based upon or otherwise in respect of: (a) any inaccuracy in or breach of any representation or warranty of the UPREIT made in or pursuant to this Agreement and/or to be made pursuant to the Put or the Call; and (b) any failure of the UPREIT to perform any obligation relating to the Put or the Call.

(c) Procedure For Indemnification - Third Party Claims.

(i) Within thirty days after receipt by an indemnified party of notice of the commencement of any proceeding against it to which the indemnification in this Section 7 relates, such indemnified party shall, if a claim is to be made against an indemnifying party under
Section 7, give notice to the indemnifying party of the commencement of such proceeding, but the failure to so notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party, demonstrates that the defense of such proceeding is materially prejudiced by the indemnified party's failure to give such notice.

11

(ii) If any proceeding referred to in paragraph (i) above is brought against an indemnified party and it gives notice to the indemnifying party of the commencement of such proceeding, the indemnifying party will be entitled to participate in such proceeding and, to the extent that it wishes (unless (i) the indemnifying party is also a party to such proceeding and the indemnified party determines in good faith that joint representation would be inappropriate, or (ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to defend such proceeding and provide indemnification with respect to such proceeding), to assume the defense of such proceeding with counsel reasonably satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under Section 7 for any fees of other counsel or any other expenses with respect to the defense of such proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such proceeding, other than reasonable costs of investigation. If the indemnifying party assumes the defense of a proceeding, (A) it will be conclusively established for purposes of this Agreement that the claims made in that proceeding are within the scope of and subject to indemnification; (B) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party's consent unless (l) there is no finding or admission of any violation of applicable law by the indemnified party (or any affiliate thereof) or any violation of the rights of any Person and no effect on any other claims that may be made against the indemnified party, and (2) the sole relief provided is monetary damages that are paid in full by the indemnifying party. The indemnified party will have no liability with respect to any compromise or settlement of the claims underlying such proceeding effected without its consent. If notice is given to an indemnifying party of the commencement of any proceeding and the indemnifying party does not, within ten days after the indemnified party's notice is given, give notice to the indemnified party of its election to assume the defense of such proceeding, the indemnifying party will be bound by any determination made in such proceeding or any compromise or settlement effected by the indemnified party.

12

(iii) Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, with respect to those issues, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such proceeding, but the indemnifying party will not be bound by any determination of a proceeding so defended or any compromise or settlement effected without its consent.

(d) Procedure for Indemnification - Other Claims. A claim for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought.

(e) Transfers by Class A Partners. Without limiting any other applicable restrictions or limitations on the transfer of Units, no Class A Partner shall distribute or otherwise transfer to any other person or entity any Units issued pursuant to this Agreement unless such person or entity first executes and delivers to the Trust and the UPREIT an agreement, in form and substance reasonably satisfactory to the Trust and the UPREIT, by which such person or entity would agree to be bound by the indemnification provisions hereof.

13

(f) Right of Set-Off. The Trust and the UPREIT shall have the right to set-off, against any Consideration or Units which may be owed by the Trust or the UPREIT to any Class A Partner or any distributions with respect thereto (including without limitation any Consideration payable on account of the exercise of the Put or the Call), any amount owed by any Class A Partner to any Preit Indemnitee pursuant to this Agreement, the Contribution Agreement or any of the other agreements, documents or transactions contemplated hereby or thereunder, including without limitation the indemnification provisions of
Section 9 of the Contribution Agreement. To the extent that a Class A Partner contests an indemnification claim of the Trust or the UPREIT that would be the basis for the exercise of a right to set off, the UPREIT shall issue such Units or other Consideration and deposit them with an escrow agent reasonably satisfactory to the UPREIT and such Class A Partner until the earlier to occur of (i) resolution of such dispute by a final nonappealable order of a court of competent jurisdiction or (ii) the mutual agreement of such Class A Partner and the UPREIT that such Units or other Consideration should be released from escrow.

(g) Indemnification Payments. The Class A Partners shall be entitled to use cash or Units to make indemnification payments hereunder. In the event Units are used, each such unit shall be valued based on the per share Value (as defined in the amended UPREIT Partnership Agreement) of a Trust Share as of the date such Unit is tendered to the Trust or the UPREIT as an indemnification payment hereunder.

(h) Survival. The obligations of the parties set forth in this Section 7 shall survive any Closing for the Put or the Call.

8. Security.

(a) Security for Call. As security for the obligations of all of the Class A Partners to honor their respective obligations under the Call, should the Call be exercised, the Class A Partners shall, contemporaneously herewith, execute and deliver to the UPREIT a Security Agreement in the form set forth on Schedule G hereto, pursuant to which they shall, until the expiration of the Call Period, pledge and grant liens on and security interests in their Retained Interests in the Partnership. The Class A Partners shall further authorize the filing of financing statements evidencing the security interests created under said Security Agreement.

14

(b) Retained Rights. As more fully set forth in the aforesaid Security Agreement, so long as the Class A Partners are not in material default of their obligations under this Agreement, the pledge and security interests granted to the UPREIT by such document shall not impair the right of the Class A Partners to receive distributions with respect to, and/or to exercise other rights attributable to, the Retained Interests.

9. Binding Effect. The covenants, terms, and provisions of this Agreement shall be binding upon and inure to benefit of the parties hereto and their respective heirs, legal representatives, successors, transferees, and assigns, and as contemplated by Section 7 hereof, the Trust, subject to the applicable restrictions on transfer as set forth in this Agreement.

10. Capacity of UPREIT. Notwithstanding that the UPREIT is a Class B Limited Partner of the Partnership, the UPREIT has entered into this Agreement not in its capacity as such limited partner but solely in its separate and independent capacity as a Delaware limited partnership existing pursuant to the UPREIT Partnership Agreement referred to herein. In no event will any of the rights, privileges or options of the UPREIT under this Agreement be limited, impaired or restricted by any provision of the Partnership Agreement (i.e., the partnership agreement of New Castle Associates) or by any past, present or future matter or thing whatsoever related to or arising out of such Partnership Agreement or the relationships, rights and/or obligations as among the partners thereof.

11. Governing Law. The laws of the Commonwealth of Pennsylvania shall govern the validity of this Agreement, the construction of its terms, and the interpretation of the rights and duties of the parties hereto.

12. Counterpart Execution. This Agreement may be executed in any number of counterparts with the same effect as if all of the parties hereto had signed the same document and any and all counterparts may be executed by facsimile. All counterparts shall be construed together and shall constitute one agreement.

15

13. Notices. All notices or other communications permitted or required under this Agreement shall be in writing and shall be sufficiently given if and when hand delivered to the persons set forth below or if sent by documented overnight delivery service or registered or certified mail, postage prepaid, return receipt requested, or telecopy, receipt acknowledged, addressed as set forth below or to such other person or persons and/or at such other address or addresses as shall be furnished in writing by any party hereto to the others. Any such notice or communication shall be deemed to have been given as of the date received, in the case of personal delivery, or on the date shown on the receipt or confirmation therefor in all other cases.

GUARANTY AGREEMENT

[CHERRY HILL]

THIS GUARANTY AGREEMENT ("Guaranty") dated as of the 24th day of April, 2003, given by PREIT ASSOCIATES, L.P., a Delaware limited partnership with an address of c/o PREIT Rubin, Inc., 2005 Broad Street, 3rd Floor, Philadelphia, PA 19102 ("Guarantor") to The Rouse Company, L.P., a Delaware limited partnership and its Affiliates (collectively, "Seller").

WHEREAS, The Rouse Company of Nevada, LLC and The Rouse Company of New Jersey, LLC (both of which are Affiliates of The Rouse Company, L.P.) have entered into an Agreement of Purchase and Sale dated March 7, 2003 (said Agreement of Purchase and Sale as it may be amended shall be referred to as the "Agreement of Sale") with PR Cherry Hill Limited Partnership, a Pennsylvania limited partnership (which, together with New Castle Associates, assignee from PR Cherry Hill Limited Partnership and any other assignee of buyer's rights under the Agreement of Sale, including any intermediary or exchange accommodation titleholder, is herein referred to as "Buyer") pursuant to which Seller will sell and Buyer will purchase one hundred percent (100%) of the membership interests of Cherry Hill Center, LLC, a Maryland limited liability company ("Owner Entity"), which owns certain Real Property known as the Cherry Hill Mall, and located in Cherry Hill, New Jersey.

(a), and (c) all costs (including, without limitation, all attorney's fees and expenses) incurred by Seller in connection with enforcing this Guaranty against Guarantor.

2. This instrument is an absolute, continuing, irrevocable, and unconditional guaranty of payment and performance, and not a guaranty of collection, and Guarantor shall remain liable on its obligations hereunder until the payment and performance in full of the Guaranteed Obligations.

- 2 -

3. The exercise by Seller of any right or remedy hereunder or under any other instrument, or at law or in equity, shall not preclude the concurrent or subsequent exercise of any other right or remedy.

4. In the event of any default by Buyer in the payment or performance of the Guaranteed Obligations, or any part thereof, when such Guaranteed Obligations are due to be paid or performed by Buyer, Guarantor shall thereupon pay or perform the Guaranteed Obligations then due in full without notice or demand, and it shall not be necessary for Seller, in order to enforce such payment or performance by Guarantor, first to institute suit or exhaust its remedies against Buyer or others.

5. If the time for payment or performance by Buyer of all or any portion of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy, or reorganization of Buyer, the Guaranteed Obligations shall nonetheless be paid or performed by Guarantor hereunder forthwith on demand by Seller.

6. Guarantor hereby agrees that its obligations under this Guaranty shall not be released, discharged, diminished, impaired, reduced, or affected for any reason or by the occurrence of any event, including, without limitation, one or more of the following events, whether or not with notice to or the consent of Guarantor: (a) the taking or accepting of collateral as security for and or all of the Guaranteed Obligations or file release, surrender, exchange, or subordination of any collateral now or hereafter securing any or all of the Guaranteed Obligations; (b) the dissolution, insolvency, or bankruptcy of Buyer, Guarantor, or any other party at any time liable for the Guaranteed Obligations;
(c) any renewal, extension, modification, waiver, amendment, assignment or re-assignment of the Agreement of Sale or any instrument, document, or agreement evidencing, securing, or otherwise relating to any or all of the Guaranteed

- 3 -

Obligations; (d) any adjustment, indulgence, release, forbearance, waiver or compromise that may be granted or given by Seller to Buyer, provided that this Guaranty shall continue to apply to the Guaranteed Obligations as so compromised (other than in connection with any bankruptcy, reorganization or insolvency proceeding); (e) any neglect, delay, omission, failure, or refusal of Seller to take or prosecute any action for the collection of any of the Guaranteed Obligations from Buyer or Guarantor; (f) any payment by Buyer or any other party to Seller is held to constitute a preference under applicable bankruptcy or insolvency law or if for any other reason Seller is required to refund any payment or pay the amount thereof to someone else; (g) any change in the existence, structure, or ownership of Buyer; (h) any other circumstance which might otherwise constitute a defense available to, or discharge of, Buyer or Guarantor, or any other party liable for any or all of the Guaranteed Obligations, other than payment, satisfaction or compromise of the Guaranteed Obligations provided that this Guaranty shall continue to apply to the Guaranteed Obligations as so compromised (other than in connection with any bankruptcy, reorganization or insolvency proceeding).

7. Guarantor represents and warrants to Seller as follows:

If the Call is exercised, the obligations of the Class A Partners to contribute the Retained Interests to the UPREIT in exchange for certain partnership units in the UPREIT, and to perform all ancillary obligations related thereto at the Closing for the Call as specified in the Call Agreement, are collectively referred to as the "Call Obligations."


2. Grant of Security Interest; Time Limitation.

(a) The Class A Partners hereby pledge and grant to the UPREIT a lien on and security interest in all of their Retained Interests ("Collateral") to secure the performance of the Call Obligations. The Collateral shall include all proceeds and products derived from or with respect to the Retained Interests.

(b) The lien and security interest granted to the UPREIT hereunder shall be released at the expiration of the Call Period, if the Call has not theretofore been exercised.

(c) The grant of rights under this Agreement and the provisions hereof shall be without prejudice to, and shall not limit, restrict or modify, any rights or remedies of the parties to the Call Agreement or the Contribution Agreement, including without limitation any rights or remedies otherwise available with respect to the Call Obligations and any indemnification or set-off rights under the Contribution Agreement or the Call Agreement.

(b) The UPREIT shall have the right to immediately obtain all benefits and privileges associated with the Collateral of the defaulting Class A Partner, and for such purposes the Partnership Agreement shall be deemed automatically amended so as to reflect the full and absolute ownership by the UPREIT of the Retained Interest of such Class A Partner, and the Class A Partners hereby designate the UPREIT as their attorney-in-fact to execute such amendments and any related certificates to be filed of record; provided that any consideration due on account of the transfer of such Retained Interest to the UPREIT, as specified in the Call Agreement, net of any costs, damages, losses or liabilities (including reasonable attorneys fees) resulting from such Class A Partner's default, shall be paid or given to such Class A Partner upon the UPREIT's acquisition of such Retained Interest free and clear of any liens, claims and encumbrances of any type or nature.

6. Rights and Remedies Cumulative.

(a) The rights and remedies of the UPREIT as provided in this Agreement or in the Call Agreement or any other documents and instruments related thereto shall be cumulative and concurrent, may be pursued separately, successively or together against Class A Partners, at the discretion of the UPREIT, and may be exercised as often as occasion therefor shall arise. The failure to exercise any such right or remedy shall in no event be construed as a waiver or release thereof.

(b) Any failure by the UPREIT to insist upon strict performance by Class A Partners of any of the terms and provisions of this Agreement or the Call Agreement, including without limitation any release of the Collateral, shall not be deemed to be a waiver of any such terms or provisions, and the UPREIT shall have the right thereafter to insist upon strict performance by Class A Partners.

7. No Transfer. During the Call Period (and if the Call is exercised, thereafter until the closing under the Call Agreement), the Class A Partners covenant and agree that they shall not sell, assign, pledge, encumber or otherwise dispose of all or any portion of the Collateral without the prior written consent of the UPREIT unless (i) such disposition is permitted by the Partnership Agreement and Call Agreement, and (ii) the transferee shall join in a copy of this Agreement to confirm its agreement to be bound by the provisions hereof.

(b) Subtractions from Capital Accounts.

(iii) The Book Values of Partnership property shall be increased (or decreased) to reflect any adjustments to the adjusted basis of such property pursuant to ss.734(b) or ss.743(b) of the Code, but only to the extent that such adjustments are taken into account in determining Capital Accounts pursuant to Regulation ss.1.704-1(b)(2)(iv)(m).

(iv) The Book Value of Partnership property shall be adjusted by the Depreciation taken into account with respect to such property.

After taking into account any special allocations pursuant to Section 4.02 and subject to any limitations contained therein, Profits and Losses for any year or portion thereof shall be allocated among the Partners in accordance with this Section 4.01.

(a) Profits. Profits shall be allocated among the Partners as follows:

(i) First, among the Partners who have previously been allocated Losses pursuant to Section 4.01(b)(iv) in the same proportion as such Losses have been allocated, until the cumulative Profits allocated to each Partner pursuant to this Section 4.01(a)(i) equal the cumulative Losses allocated to each Partner pursuant to Section 4.01(b)(iv);

(ii) Then, among the Class A Limited Partners in proportion to their relative Percentage Interests until the cumulative Profits allocated to the Class A Limited Partners pursuant to this Section 4.01(a)(ii) exceed the cumulative Losses allocated to the Class A Limited Partners pursuant to Section 4.01(b)(iii) by an amount equal to the cumulative amount of the Preferred Return paid or accrued to the Class A Limited Partners;

(iii) Then, among the Class B Limited Partners in proportion to their relative Percentage Interests until the cumulative Profits allocated to the Class B Limited Partners pursuant to this Section 4.01(a)(iii) exceed the cumulative Losses allocated to the Class B Limited Partners pursuant to Section 4.01(b)(ii) by an amount equal to the cumulative amount of the Preferred Return paid or accrued to the Class B Limited Partners;

(iv) Then, among all of the Partners in accordance with their Percentage Interests.

Provided, however, that all Profits during the period ending twelve months after the date of this Agreement in excess of the amount allocated to the Class A Limited Partners pursuant to Section 4.01(a)(ii) shall be allocated among the Class B Limited Partners and the General Partner in proportion to their relative Percentage Interests.

(b) Losses. Losses shall be allocated among the Partners as follows:

(i) First, among the Partners who have previously been allocated Profits pursuant to Section 4.01(a)(iv) in the same proportion as such Profits have been allocated, until the cumulative Losses allocated to each Partner pursuant to this Section 4.01(b)(i) equal the cumulative Profits allocated to each Partner pursuant to Section 4.01(a)(iv);

11

(ii) Then, among the Class B Limited Partners in proportion to their relative Percentage Interests until the cumulative Losses allocated to the Class B Limited Partners pursuant to this Section 4.01(b)(ii) equal the cumulative Profits allocated to the Class B Limited Partners pursuant to Section 4.01(a)(iii);

(iii) Then, among the Class A Limited Partners in proportion to their relative Percentage Interests until the cumulative Losses allocated to the Class A Limited Partners pursuant to this Section 4.01(b)(iii) equal the cumulative Profits allocated to the Class B Limited Partners pursuant to Section 4.01(a)(ii);

(iv) Then, among all of the Partners in accordance with their Percentage Interests.

(c) The Partners intend that the allocations of Profits and Losses in
Section 4.01(a) and Section 4.01(b) result in a Capital Account balance for each Partner on liquidation of the Partnership that is equal to the amount that would be distributed to such Partner if liquidating distributions were made in accordance with Article 3 of this Agreement. In the year of liquidation of the Partnership, if the allocations set forth in Section 4.01(a) and Section 4.01(b) would result in Capital Account balances that are not as described in the preceding sentence, Profits and Losses and, if necessary, items of gross income and deduction shall be specially allocated among the Partners to the extent necessary to cause each Partner's Capital Account balance to be equal to the amount that would be distributed to such Partner if liquidating distributions were made in accordance with Article 3 of this Agreement.

Section 4.02 Special Allocations.

(a) Limitation on Allocation of Items of Loss or Deduction. No Partnership items of loss or deduction may be allocated to any Partner to the extent such allocation would result in an Adjusted Capital Account deficit balance for such Partner. Any items of loss or deduction that are prohibited to be allocated to a Partner under the preceding sentence shall be reallocated among the other Partners to whom such limitation does not apply in accordance with their relative Percentage Interests. If, at the end of a year, any Partner has an Adjusted Capital Account deficit balance, such Partner shall be allocated items of gross income and gain to the extent necessary to eliminate such deficit balance.

(b) Nonrecourse Deductions and Partnership Minimum Gain Chargeback. Nonrecourse Deductions shall be allocated among the Partners in accordance with their Percentage Interests. If there is a net decrease in Partnership Minimum Gain for any year, each Partner shall be allocated the next available items of income and gain for such year (and for subsequent years if necessary) equal to such Partner's share of the net decrease in Partnership Minimum Gain as determined in accordance with Regulation ss.1.704-2(g) and the "minimum gain chargeback" requirement of Regulation ss.1.704-2(f).

12

(c) Partner Nonrecourse Deductions and Chargeback. Partner Nonrecourse Deductions for any year shall be allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable as determined under Regulation ss.1.704-2(i). If there is a net decrease in Partner Nonrecourse Debt Minimum Gain in any year, each Partner shall be allocated items of income and gain for such year (and for subsequent years if necessary) equal to such Partner's share of the net decrease in Partner Nonrecourse Debt Minimum Gain in accordance with Regulation ss.1.704-2(i)(4).

(d) Qualified Income Offset. Any Partner who unexpectedly receives, with respect to the Partnership, an adjustment, allocation, or distribution of any item described in subsections (4), (5), or (6) of Regulation ss.1.704-1(b)(2)(ii)(d) shall be allocated items of income and gain in an amount sufficient to eliminate such Partner's Adjusted Capital Account deficit balance arising thereby as quickly as possible, in accordance with the "qualified income offset" rule of Regulation ss.1.704-1(b)(2)(ii)(d)(3).

(e) Curative Allocations. The special allocations set forth in this
Section 4.02 are intended to comply with the requirements of the Regulations under ss.704(b) of the Code. It is the intent of the Partners that all such special allocations shall be offset with other special allocations. Accordingly, to the extent consistent with the Regulations, to the extent that any such special allocations are made to a Partner, subsequent offsetting special allocations shall be made to such Partner such that the net amount of all items of income, gain, loss and deduction allocated to each Partner is the same that would have been allocated to each Partner if no special allocations had been made to any Partner, taking into account future special allocations that, although not yet made, are likely to offset previous special allocations.

Section 4.03 Allocation During Year. For purposes of determining Profits, Losses, or any other items allocable to any period ending on a date other than the last day of the Partnership's year, Profits, Losses, and any such other items shall be allocated among such periods using such method permitted by ss.706 of the Code and the Regulations thereunder as shall be chosen by the General Partner.

Section 4.04 Tax Allocations.

(a) General Allocation. Except as otherwise provided in this Section 4.04, items of income, gain, loss and deduction as determined for federal income tax purposes shall be allocated in the same manner as the related items of Profits, Losses, or specially allocated items. Tax credits shall be allocated in accordance with Regulation ss.1.704-1(b)(4)(ii).

(b) Contributed Property. In accordance with ss.704(c) of the Code and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for federal income tax purposes and its Book Value.

13

(c) Revaluations. If the Book Value of any Partnership property is adjusted pursuant to Section 2.04(d)(ii) of this Agreement, income, gain, loss and deduction with respect to such property shall be allocated among the Partners so as to take account of any variation between the adjusted basis of such property for federal income tax purposes and its Book Value in the same manner as under ss.704(c) of the Code and the Regulations thereunder.

(d) No Effect on Capital Accounts. Allocations pursuant to this Section 4.04 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Partner's Capital Account or share of Profits, Losses, or other items or distributions pursuant to any provision of this Agreement.

(e) Allocation Method. The method for making allocations pursuant to
Section 4.04(b) and Section 4.04(c) shall be such method permitted by Regulation ss.1.704-3 as shall be selected by the General Partner.

Section 7.01 Transfers. Except as provided in this Agreement, no Partner shall Transfer all or any portion of the Partner's Interest without the written consent of the General Partner, which consent may be withheld in the sole discretion of the General Partner. In connection with any permitted Transfer, if required by the General Partner the transferee shall provide the Partnership with a written opinion from legal counsel acceptable to the General Partner that such transfer will not violate any state or federal securities law, and will not cause a termination of the Partnership under Section 708(b)(1)(B) of the Code. The transferee shall pay all costs and expenses incurred by the Partnership in connection with such Transfer. With respect to any Interest held by an entity other than UPREIT, each such entity agrees that it will not permit any of its direct or indirect owners to Transfer all or any part of their direct or indirect ownership interests in such entity except in accordance with this
Section 7.01. Any purported Transfer in violation of this Agreement shall be null and void. The Partners acknowledge that the restrictions on Transfers contained herein are reasonable and necessary to protect the interests of the Partners with respect to the Partnership. If in connection with a permitted Transfer of an Interest the transferor requests that the Partnership make an election under Section 754 of the Code and provides the Partnership with the information required by Regulation ss.1.743-1(k), the General Partner shall cause the Partnership to make the election under Section 754 of the Code provided such election does not result in a negative adjustment to the tax basis of the Partnership's assets with respect to any other Partner. If there is a Transfer of any Interest, the Interest as to the transferee shall be of the same Class as the transferred Interest had in the hands of the transferor, regardless of whether the transferee also holds any Interest of any other Class and regardless of whether the transferee is admitted as a Limited Partner with respect to such Class pursuant to Section 7.02.

Section 7.02 Admissions. Except as provided in this Agreement, no transferee of an Interest shall be admitted as a Partner of the Partnership without the written consent of the General Partner, and only if the transferee agrees to be legally bound by this Agreement as a Partner and executes and delivers to the Partnership such documents and instruments as are necessary or appropriate in connection with the transferee becoming a Partner. The transferee shall pay all costs and expenses incurred by the Partnership in connection with such admission. Any transferee of an Interest who is not admitted as a Partner shall have the rights of an assignee with respect to distributions and Profits, Losses, and other allocations attributable to the transferred Interest, but shall have no rights as a Partner under this Agreement or the Act.
Notwithstanding the foregoing, the Interest of the assignee shall be subject to the restrictions contained in this Agreement applicable to Interests held by a Limited Partner.

The satisfaction of any indemnification shall be from and limited to Partnership's assets and no Partner shall have any liability on account thereof. The right to indemnification shall include the right to be paid or reimbursed by the Partnership the reasonable expenses incurred by the Indemnified Party in advance of the final disposition of any proceeding; provided, however, that the advance payment of such expenses shall be made only upon delivery to the Partnership of a written affirmation by such Indemnified Party of such Indemnified Party's good faith belief that the Indemnified Party has met the standard of conduct necessary for indemnification under this Agreement and a written undertaking, by or on behalf of such Indemnified Party, to repay all amounts so advanced if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified under this Agreement or otherwise.

REPRESENTATIONS AND WARRANTIES

This Agreement constitutes the legal, valid, and binding obligation of each Partner.

18

(b) No Conflict or Default. The execution, delivery, and performance of this Agreement and the consummation by such Partner of the transactions contemplated hereby (i) will not conflict with, violate, or result in a breach of any of the terms, conditions, or provisions of any law, regulation, order, writ, injunction, decree, determination, or award of any court, any governmental department, board, agency, or instrumentality, or any arbitrator, applicable to such Partner, and (ii) will not conflict with, violate, result in a breach of, or constitute a default under any of the terms, conditions, or provisions of the articles of incorporation, bylaws, partnership agreement, operating agreement, or other organizational documents of such Partner, or of any material agreement or instrument to which such Partner is a party or by which such Partner is or may be bound or to which any of its material properties or assets are or may be subject.

(c) Governmental Authorizations. Any registration, declaration or filing with or consent, approval, license, permit or other authorization or order by, any governmental or regulatory authority that is required in connection with the valid execution, delivery, acceptance, and performance by such Partner under this Agreement or the consummation by such Partner of any transaction contemplated hereby has been completed, made, or obtained on or before the effective date of this Agreement.

There are no actions, suits, proceedings, or investigations pending or, to the knowledge of such Partner, threatened against or affecting such Partner or any of such Partner's properties, assets, or businesses in any court or before or by any governmental department, board, agency, instrumentality, or arbitrator which, if adversely determined, could (or in the case of an investigation could lead to any action, suit, or proceeding which, if adversely determined, could) reasonably be expected to materially impair such Partner's ability to perform its obligations under this Agreement.

Section 10.02 Investment Representations. Each Limited Partner represents and warrants that it has acquired its Interest for its own account as part of a transaction exempt from registration under the Securities Act of 1933, as amended, and applicable state law for investment purposes and not with a view to the resale or distribution thereof, and that it has had access to any and all information necessary to arrive at its decision to acquire its Interest. In addition to the restrictions on transfer of Interests otherwise set forth in this Agreement, no Interest may be sold, transferred, assigned or otherwise disposed of by any Partner in the absence of registration under the Securities Act of 1933, as amended, and applicable state law, or an opinion of counsel experienced in securities matters and satisfactory to the General Partner that such assignment or other disposition will not be in violation of said Act or state laws. No Limited Partner shall have any right to require registration of its Interest under said Securities Act or applicable state law and, in view of the nature of the Partnership and its business, such registration is neither contemplated nor likely. Each Limited Partner further acknowledges that it understands that the effect of the foregoing representation and warranty and restriction on assignment or other disposition is generally to require that such Interest be held indefinitely unless it is registered or an exemption from registration is available.

The Agent shall notify the Owner of the necessity for, the nature of, and the cost of any such emergency repairs or compliance. If Owner shall require, Agent shall submit, for Owner's prior written approval, a list of contractors and subcontractors performing tenant work, repairs, alterations or services at the Premises, under Agent's direction.

(f) request from tenants any certificates of insurance and renewals thereof required to be furnished by the terms of leases, copies of which will be provided to the Owner upon request.

(g) receive and collect rent and all other monies payable to the Owner by all tenants and licensees in the Premises and to deposit the same promptly in the bank (the "Bank") named in Exhibit B in a bank account (the "Bank Account") in the name of Agent, as Agent for the Owner, which Bank Account shall be used exclusively for such funds. In the event state law requires tenant security deposits be held in a separate account, such account shall be established by the Agent as approved by the Owner.

The Owner or the Owner's designated representative will be a signatory on the Bank Account, but need not co-sign each check.

(h) collect such rent and other charges from tenants in a timely manner and to pursue Owner's legal remedies for non-payment of same, including the termination of leases for tenants in default by the institution of legal action. Agent shall refer all such matters requiring legal services to Agent's approved attorneys listed on Exhibit B hereto or, at Agent's option, have such legal work performed by Agent's in-house attorneys or paralegals. The fees for all such legal services shall be paid for by Owner, including (i) negotiation of leases, including department store leases and reciprocal easement agreements; (ii) preparation and negotiations of construction contracts for renovations of the Premises; (iii) suits to enforce leases; (iv) bankruptcy claims involving tenants; (v) negotiations with labor unions; (vi) environmental matters and

Agent may deduct the amount to be reimbursed from the Bank Account. With respect to any litigation involving sums due from tenants, Agent is authorized to compromise such litigation without Owner's consent so long as such compromise does not involve a forgiveness of sums due by such tenant in excess of Fifteen Thousand ($15,000.00) Dollars.

-5-

Such compliance shall be undertaken in the name of Owner, and be at Owner's expense. Agent shall give prompt written notice to Owner of any violation or notice of alleged violation of such laws and Agent shall not bear responsibility for failure of the Premises or the operation thereof to comply with such laws unless Agent has committed gross negligence or a willful act or omission in the performance of its obligations under this Agreement.

In the event Agent determines that there is not sufficient funds in the Bank Account to pay when due all expenses of the Premises and reimbursements due Agent, Owner shall, within five (5) days of request, deposit into such account additional funds in the amount requested by Agent. The Agent agrees to keep full and detailed records with respect to the management and operation of the Premises and to retain those records for periods specified by the Owner, not to exceed three (3) years after the year in question. The Owner shall have the right to inspect such records and audit the reports required by this Section during business hours for the life of this Agreement, and at times mutually agreeable to Owner and Agent.

2.3 The Agent shall exercise reasonable diligence to exert such control over accounting and financial transactions as is reasonably required to protect the Owner's assets from loss or diminution due to error, negligence or willful misconduct or wanton acts on the part of the Agent, its employees, agents or contractors. Losses caused by failure to exercise reasonable diligence shall be borne by Agent.

2.4 The Agent shall prepare and submit to the Owner a proposed operating and capital budget for the promotion, operation, repair and maintenance of the Premises for each calendar year. Preliminary and final budgets will be due ninety (90) and sixty (60) days, respectively, prior to the end of each calendar year. Such budgets shall be prepared on a cash basis showing a month by month projection of income and expense and capital expenditures and shall be accompanied by proposed leasing guidelines for the next ensuing calendar year which shall contain a brief narrative description of the anticipated market, a projection of cash flow for such year, listing expiring leases for the next following year as well as project ranges of rental rates and terms for new or renewal leases, estimates of concessions to tenants and of cost estimates of alterations for space to be leased. The annual budget shall be deemed approved unless Agent receives written notification of disapproval within thirty (30) days after the date such budget was tendered to Owner for approval; Owner shall have the right to disapprove line items in such budget or the entire budget. In the event of a line item disapproval, all portions of the budget not disapproved shall automatically be deemed approved. In the event of such disapproval of the budget or any specific line items thereof, the parties will promptly meet and resolve such differences and Agent will promptly thereafter resubmit a revised budget to Owner who shall have an additional ten (10) days to approve or disapprove the same and such procedure shall continue until the budget has been approved. If Owner shall fail to disapprove the revised budget within ten (10) days of receipt, the same shall be deemed approved. Agent is authorized for the account of Owner to make any expenditures or to incur any obligations or implement any items which are included in the approved annual budget without further approval from owner being required. Such budgets and all other financial reporting to be prepared by Agent shall be prepared using Agent's then standard format and software. Agent shall not be obligated to use any other financial format or software unless same is satisfactory to Agent, Owner purchases same for Agent and Owner pays all of the training expenses for Agent's employees relating to such software.

-7-

After approval of each such budget by the Owner, the Agent agrees to use diligence and to employ all reasonable efforts so that the actual costs of operating the Premises shall not exceed said approved budget by more than ten (10%) percent per year without the Owner's approval. The Agent shall promptly notify the Owner if the Agent reasonably anticipates any such line item exceeding one hundred ten (110%) percent of the amount therefor in the approved budget.

2.5 Agent agrees, for itself and all persons retained or employed by Agent in performing its services, to hold in confidence and not to use or disclose to others any confidential or proprietary information of Owner heretofore or hereafter disclosed to Agent including, but not limited to, any data, information, plans, programs, processes, costs, operations or tenants which may come within the knowledge of Agent in the performance of or as a result of its services, except where Owner specifically authorizes Agent to disclose any of the foregoing to others or such disclosure reasonably results from the performance of Agent's duties hereunder or is required to be disclosed pursuant to litigation.

2.6 The Agent agrees to use its best efforts to have the Premises rented to desirable tenants, satisfactory to the Owner considering the nature of the Premises, and in connection therewith to negotiate business terms for relocation and/or expansions, new leases and renewals of leases at appropriate times, it being understood that all inquiries to the Owner with respect to leasing any portion of the Premises shall be referred to the Agent. At least once per year Owner and Agent shall meet and mutually develop a "leasing game plan" for the ensuing calendar year which game plan shall specify projected vacancies, projected rentals and other pertinent terms of new leases or lease renewals, costs to be incurred in obtaining tenants and other relevant matters. Owner hereby authorizes Agent to implement the approved leasing game plan and to negotiate and execute leases in accordance therewith and confirms that any leases so executed shall be deemed approved by Owner and Owner shall pay Agent the leasing commission set forth in this Agreement with respect to each lease executed by a tenant consistent with the leasing game plan. Agent is hereby given the exclusive right to lease the Premises on behalf of Owner and Owner shall pay to Agent the leasing commission set forth in Exhibit B regardless of who may negotiate the same, including Owner. All leases and renewals shall be prepared by the Agent on the Agent's form lease, and such leases shall either be executed by Agent on behalf of Owner or, at Agent's option shall be executed by the Owner. The Agent agrees it will observe the specific leasing guidelines, if any, set forth in the approved budget or otherwise made known to the Agent in writing by the Owner. In the event the Agent shall have a prospective tenant reference from another property in the local market area where the Premises are located in which the Agent has a beneficial interest or which the Agent manages, the Agent shall declare its potential conflict of interest to the Owner, and the Owner shall determine if negotiations shall be undertaken by the Agent, the Owner, or a third party appointed by the Owner. References of prospective tenants, as well as their varying use requirements, shall be investigated by the Agent.

-8-

2.7 Anything in the Agreement to the contrary notwithstanding:

(a) Nothing in this Agreement shall require Agent to take any action (and Agent will not be in default for failure to take any action) to the extent and wherever there is provided a limitation on Agent's ability to expend funds or incur obligations with respect to the Premises.

(b) Unless expressly provided, Agent shall not be responsible or obligated to advance its own funds for any purpose in the performance of Agent's duties under this Agreement.

(c) Agent shall not be obligated to pay or perform any liability or obligation or take any action under this Agreement which is to be done at the expense of Owner or for which Agent is entitled to reimbursement from Owner unless funds for such purpose are available in the Bank Account or have otherwise been made available to Agent by Owner.

(d) Wherever Agent is obligated to use its "best efforts or reasonable efforts" under this Agreement such term is intended to signify and shall mean that Agent shall exercise its professional skill and expertise with diligence and in a commercially reasonable manner and consistent with high quality practice for the management of similar buildings located in the geographic area in which the Premises are situate. However, such a standard shall not impose additional duties or obligations on Agent not set forth in this Agreement, such as, by way of example, an obligation to advance Agent's funds or to commence litigation against third parties, or to take extraordinary actions or to perform services not customarily provided by managers of comparable buildings in the local geographic area. Nothing in this Agreement shall require Agent to perform the obligations of others or exercise any efforts (other than reasonable efforts) to cause them to perform such obligations.

-9-

(e) Everything done by Agent in the performance of its obligations under this Agreement and all expenses incurred pursuant hereto shall be for and on behalf of Owner and for its account and at its expense. Except as otherwise expressly provided herein, all debts and liabilities incurred to third parties in accordance with the annual budget and in the ordinary course of business of managing the Premises are and shall be obligations of Owner, and Agent shall not be liable for any such obligations by reason of its management, supervision or operation of the Premises for Owner.

THE OWNER'S AGREEMENTS

3.1 The Owner, at its option, may pay directly all taxes, special assessments, ground rents, insurance premiums and mortgage payments, in which event Owner shall notify Agent of such.

3.2 The Owner shall carry (or cause to be carried) insurance upon the Premises and shall look solely to such insurance for indemnity against any loss or damage to the Premises except when caused by the willful act or omission or gross negligence of the Agent or its employees, agents, contractors or subcontractors. However, Agent shall not be liable to Owner for any loss or damage to the Premises even if caused by the willful act or omission or gross negligence of Agent or its employees, agents, contractors or subcontractors to the extent any such loss or damage is covered or should have been covered by Owner's insurance. To the extent any loss or damage to the Premises is covered or should have been covered by Owner's insurance, Agent is released from liability therefor and Owner waives its right of subrogation against Agent. The Owner shall purchase, or have Agent purchase for Owner and at Owner's expense, and maintain policies of commercial general liability insurance, including personal injury liability and contractual liability, in an amount determined by Agent but, in any event not less than $5,000,000.00 combined single limit for bodily injury and property damage. Said policies shall name the Agent as an additional insured thereunder and will be primary to any other available insurance. The Owner shall advise the Agent as to the name and address of any insurance carriers for insurance placed by Owner directly.

3.3 Owner agrees (a) to indemnify, hold and save Agent free and harmless from any claim for damages or injuries to persons or property resulting from: (1) Agent carrying out the provisions of this Agreement or acting under direction of Owner, (2) Owner's failure or refusal to comply with or abide by any rule, order, determination, ordinance or law of any federal, state or municipal authority, (3) Owner's failure or refusal to comply with or abide by or perform its obligations set forth in this Agreement, (4) any latent building defects or other defect or dangerous condition which a visual inspection would fail to disclose or any unsafe or dangerous condition or characteristic of the Premises resulting from the design or initial construction of the Premises (including, but not limited to, security systems, door locks, location of trash receptacles, ingress & egress routes and recreational structures), (5) any defects, conditions or situations with respect to the Premises which Agent has disclosed to Owner and requested Owner's permission to correct or rectify, (6) the willful misconduct or criminal activity of any third person or agency, except as to Agent and its employees, agents and representatives with respect to the Premises or (7) the negligent or willful acts of Owner or Owner's representatives, officers, employees and agents; and (b) to defend promptly and diligently at Owner's expense, any claim, action or proceeding against Agent and/or Agent and Owner, jointly or severally, arising out of or connected with any of the foregoing, and to hold harmless and fully indemnify Agent from any judgment, loss or settlement on account thereof. The undertaking of Owner as set forth above shall survive the expiration or earlier termination of this Agreement as to all liabilities accruing during the term hereof.

-10-

3.4 If Owner requests Agent to perform certain designated additional management services and the parties agree to the exact nature, scope and time frame for the performance thereof, then Owner shall pay the Agent the agreed upon fee for Agent's performance of such services, such payment to be made within twenty (20) days after receipt of a bill therefor. Such payment shall be made in addition to the fees and reasonable expenses otherwise stated herein. In performing any specialized management services for Owner, Agent shall not be liable to Owner for errors, accuracies, mistakes or the consequences thereof, relating to the performance of such services provided Agent has performed the services in good faith. Owner hereby waives, releases and discharges Agent from all errors, inaccuracies, mistakes and the consequences thereof relating to the performance of such services, except to the extent Agent has not performed such services in good faith.

3.5 The Owner hereby irrevocably appoints Agent as the sole and exclusive broker for any sale and/or re-financing of the Premises and agrees to pay Agent a fee of one (1%) percent of the principal amount of any refinancing and a sales commission of two (2%) percent of the gross sales price for the Premises, each such fee to be paid at the closing involved. Such fee shall include Agent's fee for any due diligence work required to accomplish such refinancing and/or sale.

3.6 Owner agrees to make available to Agent, free of charge, an on-site office to be utilized in connection with Agent's leasing of the Premises. In addition, Owner shall reimburse Agent monthly for all travel expenses, leasing and marketing materials, demographic and marketing studies signage and advertising incurred by Agent during the performance of its obligations under this Agreement. Agent shall have the right to install signage on the Premises in furtherance of its obligation to lease the Premises. Owner shall cause the Premises to participate in Agent's wide area network data transmission system and shall lease or purchase for the Premises any wiring, phone, computers, routers or software upgrades that Agent deems necessary to access the system.

-11-

3.7 Agent has afforded Owner the benefit of Agent's blanket policy of workmen's compensation insurance. Such policy provides that Agent is required to pay in full, in advance, the annual premium for such policy. Owner shall reimburse Agent, on demand, its share of such premium, such share being determined by the actual payroll and rate classifications statutorily mandated in the state where the Premises is located. Owner acknowledges that should this contract be terminated during the policy year, there shall be no proration of Owner's premium payment as between Owner and Agent unless or until Agent receives a refund for the unused portion of such premium from the insurance carrier.

Owner acknowledges that Agent will allocate to the marketing fund/merchant's association, as applicable, certain costs of Agent's marketing program maintained from Agent's home office.

Commissions will be based on base rents including CPI inflators payable to Owner, percentage rent and all additional rental payable by the tenant. When leases are negotiated by third party broker, the Agent shall cooperate with such brokers. The Owner shall pay the commission due any such third party broker so long as the Owner has approved in advance the use of such broker and the commission to be paid such broker and such payment shall not reduce the fees provided herein payable to Agent. The leasing commission will be paid to Agent if within a period of six (6) months after the expiration of the term of this Agreement Owner leases all or any portion of the Premises, irrespective of the terms of such lease, to any prospect introduced to the Premises by Agent prior to the expiration of the term, provided that Agent shall have informed Owner in writing of the name of the prospect within thirty (30) days after the expiration of the term hereof.

REGISTRATION RIGHTS

Section 2.1 Registration of Registrable Securities.

(a) In the event that any Applicable Units are issued by the Operating Partnership pursuant to the Call-Put Agreement, then the Trust shall prepare and file with the SEC, and use its commercially reasonable efforts to cause to become effective, within six months following the Closing Date, a registration statement on Form S-3 (or, if Form S-3 is not then available, on such form of registration statement as is then available to effect a registration of all of the Registrable Securities to be so registered) covering the resale of all of the Shares issuable in connection with the redemption of the Applicable Units issued to the Holders on the Closing Date.

(b) Notwithstanding the foregoing provisions of this Section 2.1, but subject to Section 2.7(b), in the event that the Trust is required to prepare and file a registration statement covering Registrable Securities pursuant to paragraph (a) above, the Trust shall have the right, upon written notice to the Holders, to defer the filing or effectiveness of such registration statement for up to 90 days (the number of days of any such deferral being hereinafter referred to as the "Registration Deferral Period") if (i) the Trust is, at such time, working on an underwritten public offering of its securities for the account of the Trust and is advised by its managing underwriter that such offering would in its opinion be materially adversely affected by such a filing; or (ii) the Trust determines reasonably and in good faith that the filing or effectiveness of such a registration statement, or the offering of Registrable Securities pursuant thereto, would require the disclosure of material non-public information, the disclosure of which at such time could reasonably be expected to have a material adverse effect on the business or affairs of the Trust or a material adverse effect on any proposal or plan by the Trust or any of its subsidiaries to engage in any extraordinary engagement or activity, including, without limitation, any material acquisition of assets or any merger, consolidation, tender offer or similar transaction.

3

Section 2.2 Obligations of the Trust. Whenever required under Section 2.1 to effect the registration of any of the Registrable Securities, the Trust shall, as expeditiously as reasonably possible:

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use reasonable efforts to (i) cause such registration statement to become effective in order to permit the sale of the Registrable Securities by the Holders in accordance with the intended method or methods of distribution thereof described in such registration statement and
(ii) maintain the effectiveness of such registration statement as to the Registrable Securities covered thereby until the earlier of (A) the date on which the Holders no longer hold any of the Registrable Securities covered thereby or any of the Applicable Units to which the Registrable Securities covered thereby relate, or (B) the date on which all of the Registrable Securities included in such registration statement have ceased to constitute Registrable Securities, after which the Trust may deregister such Registrable Securities;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in paragraph (a) above;

(c) furnish to the Holders such number of copies of the prospectus, including all amendments and supplements thereto, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

(d) comply in all material respects with the provisions of the Securities Act applicable to the Trust with respect to the disposition of all of the Registrable Securities covered by such registration statement in accordance with the intended method or methods of disposition by the Holders;

(e) use reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided, however, that the Trust shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

4

(f) (i) promptly notify the Holders, and, if requested, confirm such notification in writing, (A) when a prospectus or any prospectus supplement has been filed with the SEC and when the registration statement or any post-effective amendment thereto has been filed with and declared effective by the SEC, (B) of the issuance by the SEC of any stop order or the coming to its knowledge of the initiation of any proceedings for that purpose, (C) of the receipt by the Trust of any notification with respect to the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (D) of the occurrence of any event that requires the making of any changes to the registration statement or related prospectus so that such documents will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (E) of the Trust's determination that the filing of a post-effective amendment to the registration statement shall be necessary or appropriate; and (ii) upon the occurrence of any event of the kind described in clauses (B), (C) (but only with respect to the jurisdiction suspending qualification), (D) or (E), above, as promptly as practicable thereafter, take such action as shall be necessary to remedy such event to permit the Holders to continue to offer and dispose of the Registrable Securities, including, without limitation, preparing and filing with the SEC and furnishing to the Holders a supplement or amendment to such prospectus so that, as thereafter deliverable to the purchasers of the Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(g) make available to the Holders and any attorney, accountant or other agent or representative retained by the Holders (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of the Trust, as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Trust's officers, directors and employees to supply all information reasonably requested by any such Inspector in connection with such registration statement, subject, in each case, to such confidentiality agreements as the Trust shall reasonably request;

(h) use reasonable efforts to cause the Registrable Securities covered by such registration statement to be listed on the securities exchange or quoted on the quotation system on which similar securities issued by the Trust are then listed or quoted;

(i) otherwise use reasonable efforts to cooperate with the SEC and any other regulatory agencies and take all reasonable actions and execute and deliver or cause to be executed and delivered all documents reasonably necessary to effect and maintain the effectiveness of the registration of any Registrable Securities under this Agreement; and

(j) during the period when a prospectus is required to be delivered under the Securities Act, promptly file all documents required to be filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act.

5

Section 2.3 Obligations of the Holder.

(a) It shall be a condition precedent to the obligation of the Trust to register the Registrable Securities of any Holder pursuant to Section 2.1 that such Holder shall furnish to the Trust, upon request, such information regarding itself, its Registrable Securities and the intended method of disposition of such Registrable Securities as shall be reasonably required to effect the registration of such Registrable Securities.

(b) Each Holder shall (i) offer to sell or otherwise distribute the Registrable Securities in reliance upon a registration contemplated by this Agreement only after a registration statement shall have been filed with the SEC, (ii) sell or otherwise distribute the Registrable Securities in reliance upon a registration only after a registration statement has been filed and declared effective under the Securities Act, (iii) upon the receipt of any notice from the Trust of the occurrence of any event of the kind described in
Section 2.2(f)(i)(B), (C) (but only with respect to the jurisdiction suspending qualification), (D) or (E), forthwith discontinue any offer and disposition of the Registrable Securities pursuant to the registration statement covering such Registrable Securities until such time as the Trust shall have remedied such event or prepared an appropriate amendment or supplement to the prospectus covering such Registrable Securities and, if so directed by the Trust, deliver to the Trust all copies of the defective prospectus covering such Registrable Securities that are then in such Holder's possession or control, (iv) distribute the Registrable Securities in reliance upon a registration contemplated by this Agreement only in accordance with the manner of distribution contemplated by the prospectus and (v) report to the Trust distributions made by such Holder of Registrable Securities pursuant to the prospectus.

(c) During any period that a registration statement filed pursuant to this Agreement shall remain effective, no Holder shall (i) effect any stabilization transactions or engage in any stabilization activity in connection with the Shares or other equity securities of the Trust in contravention of Regulation M under the Exchange Act, or (ii) permit any "Affiliated Purchaser" (as that term is defined in Regulation M under the Exchange Act) to bid for or purchase for any account in which such Holder has a beneficial interest, or attempt to induce any other person to purchase, any Shares or other equity securities of the Trust in contravention of Regulation M under the Exchange Act.

(d) If the Trust is issuing or selling equity securities to the public in an underwritten offering, and the managing underwriter or underwriters for such underwritten offering so request, the Holders shall refrain from effecting any public sale or distribution of Registrable Securities or any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144 (or any similar provision then in force) under the Securities Act, for a period commencing on the tenth (10th) day prior to the date such underwritten offering commences (such offering being deemed to commence for this purpose on the later of the effective date for the registration statement for such offering or, if applicable, the date of the prospectus supplement for such offering) and ending 90 days after such underwritten offering commences; provided that all officers and directors of the Trust and holders of at least five percent (5%) of the Trust's Shares enter into similar agreements and subject to any concession (such as early release from such lock-up) granted to any such officers, directors or holders.

6

Section 2.4 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any registration shall be borne by the Trust. All Selling Expenses incurred in connection with any such registrations shall be borne by the Holders.

Section 2.5 Indemnification. With respect to Registrable Securities that are included in a registration statement under Section 2.1:

(a) To the extent permitted by law, the Trust shall indemnify and hold harmless the Holders, their respective Affiliates, partners, officers, directors, stockholders and agents, and any other person who controls any of the foregoing within the meaning of the Securities Act or the Exchange Act (collectively, the "Holder Indemnitees"), against any losses, claims, damages, expenses, judgments or liabilities (joint or several) to which any Holder Indemnitee may become subject, including any amount paid in settlement of any litigation commenced or threatened (unless such settlement is effected without the consent of the Trust, which consent shall not be unreasonably withheld), and shall promptly reimburse each Holder Indemnitee, as and when incurred, for any legal or other expenses incurred by such Holder Indemnitee in connection with investigating any claims and defending any actions, insofar as such losses, claims, damages, expenses, judgments or liabilities (or actions in respect thereof) shall arise out of or shall be based upon (i) any violation or alleged violation by the Trust of the Securities Act, the Exchange Act or any other securities laws, relating to action taken or action or inaction required of the Trust in connection with such offering, (ii) any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any final prospectus included therein) relating to the offering and sale of the Registrable Securities, or any amendment thereof or supplement thereto, or in any document incorporated by reference therein, or (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the indemnity agreement contained in this Section 2.5(a)(ii) and (iii) shall not apply to a Holder in any such case to the extent that any such loss, claim, damage, expense, judgment, liability or action arises out of or is based upon any untrue statement or alleged untrue statement, or any omission or alleged omission, if such statement or omission shall have been (A) made in reliance upon and in conformity with information furnished to the Trust in writing by or on behalf of such Holder Indemnitee for inclusion in such registration statement (including any final prospectus contained therein), or any amendment thereof or supplement thereto, or (B) made in any preliminary prospectus and the final prospectus shall have corrected such statement or omission and a copy of such final prospectus shall have been delivered to such Holder Indemnitee prior to the time such final prospectus is required to be delivered by such Holder Indemnitee under applicable law and such loss, claim, damage, expense, judgment, liability or action arises out of such Holder's failure to deliver such final prospectus in compliance with applicable law.

7

(b) To the extent permitted by law, each Holder shall indemnify and hold harmless the Trust, each of its officers and trustees, each person, if any, who controls the Trust within the meaning of the Securities Act or the Exchange Act and any other Holder Indemnitee (collectively, the "Trust Indemnitees"), against any losses, claims, damages, expenses, judgments or liabilities (joint or several) to which any Trust Indemnitee may become subject, including any amount paid in settlement of any litigation commenced or threatened (unless such settlement is effected without the consent of such Holder, which consent shall not be unreasonably withheld), and shall promptly reimburse each Trust Indemnitee, as and when incurred, for any legal or other expenses incurred by such Trust Indemnitee in connection with investigating any claims and defending any actions, insofar as such losses, claims, damages, expenses, judgments or liabilities (or actions in respect thereto) shall arise out of or shall be based upon (i) any violation by such Holder of Section 5 of the Securities Act in connection with such offering (other than as a result of such a violation by the Trust or any other person other than such Holder), (ii) any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any final prospectus included therein) relating to the offering and sale of the Registrable Securities, or any amendment thereof or supplement thereto, or in any document incorporated by reference therein, or (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the indemnity agreement contained in this
Section 2.5(b)(ii) and (iii) shall only apply in any such case (A) to the extent that any such loss, claim, damage, expense, judgment, liability or action arises out of or is based upon an untrue statement contained in, or a material fact omitted from, information furnished to the Trust in writing by or on behalf of such Holder for inclusion in the registration statement (or in any final prospectus included therein), and (B) if any such untrue statement or material omission is incorporated by the Trust in any preliminary prospectus, to the extent that such statement or omission shall not have been corrected in writing by or on behalf of such Holder prior to the time the final prospectus is required to be delivered by the Trust under applicable law.

(c) Promptly after receipt by an indemnified party under this
Section 2.5 of notice of the commencement of any action (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.5, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.5 to the extent of such prejudice, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.5.

8

(d) If the indemnification provided for in this Section 2.5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the circumstances that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The obligations of the Trust and the Holders under this
Section 2.5 shall survive completion of any offering of Registrable Securities in a registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

Section 2.6 Assignment of Registration Rights. The rights to cause the Trust to register Registrable Securities pursuant to this Article II may be assigned by a Holder to a transferee or assignee of Registrable Securities or Applicable Units that (a) is an Affiliate of such Holder, or (b) is a member of such Holder's immediate family or is a trust for the benefit of such Holder or a member of such Holder's immediate family; provided, however, that (i) within ten days after such transfer, the transferring Holder furnishes to the Trust written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned, and (ii) such transferee agrees to be subject to all restrictions set forth in this Agreement.

Section 2.7 Information Blackout.

(a) At any time when a registration statement covering Registrable Securities is effective, upon written notice from the Trust to the Holders that the Trust has determined reasonably and in good faith that the sale of Registrable Securities pursuant to the registration statement would require disclosure of material non-public information, the disclosure of which at such time could reasonably be expected to have a material adverse effect on the business or affairs of the Trust or a material adverse effect on any proposal or plan by the Trust or any of its subsidiaries to engage in any extraordinary engagement or activity, including, without limitation, any material acquisition of assets or any merger, consolidation, tender offer or similar transaction, the Holders shall suspend sales of the Registrable Securities pursuant to the registration statement until the earlier of (i) 45 days after the Trust notifies the Holders of such good faith determination, or (ii) such time as the Trust notifies the Holders that such material information has been disclosed to the public or has ceased to be material or that sales pursuant to the registration statement may otherwise be resumed (the number of days from such suspension of sales by the Holders until the day when such sales may be resumed hereunder being hereinafter referred to as the "Sales Blackout Period").

9

(b) In no event shall the Trust be permitted to impose Registration Deferral Periods or Sales Blackout Periods that, collectively, extend for more than 90 days in any given 12 month period.

Section 2.8 Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations under the Securities Act that may at any time permit the sale of the Registrable Shares to the public without registration, at all times that the Trust is subject to the reporting requirements of the Exchange Act, the Trust shall use its reasonable efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the SEC, in a timely manner, all reports and other documents required of the Trust under the Securities Act and the Exchange Act; and

(c) so long as a Holder owns any Registrable Securities (or Applicable Units), furnish to such Holder forthwith upon request (i) a written statement by the Trust as to its compliance with the reporting requirements of Rule 144 and of the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Trust, and (iii) such other reports and documents of the Trust as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any such securities without registration.

ARTICLE III
MISCELLANEOUS

Section 3.1 Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania (without giving effect to any conflicts or choice of law provisions that would cause the application of the domestic substantive laws of any other jurisdiction). None of the parties hereto has agreed with or represented to any other party that the provisions of this section will not be fully enforced in all instances.

Section 3.2 Cumulative Remedies; Failure to Pursue Remedies. The rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy by any party shall not preclude or waive its right to use any or all other remedies. Said rights and remedies are given in addition to any other rights the parties may have by law, statute, ordinance or otherwise. Except where a time period is specified, no delay on the part of any party in the exercise of any right, power, privilege or remedy hereunder shall operate as a waiver thereof, nor shall any exercise or partial exercise of any such right, power, privilege or remedy preclude any further exercise thereof or the exercise of any other right, power, privilege or remedy.

10

Section 3.3 Amendment and Waiver. Except as otherwise expressly provided herein, no provision of this Agreement may be amended, modified or waived except upon the written consent of the Trust and the Holders who own greater than fifty percent (50%) of the Registrable Securities (including, for this purpose, Applicable Units) then outstanding owned by all Holders. Notwithstanding the foregoing, the Trust may amend Exhibit A hereto to reflect dispositions of Registrable Securities by Holders (including the addition of new Holders as a result of any permitted assignment of the rights granted hereunder in accordance with Section 2.6) without obtaining the written consent of the Holders. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Section 3.4 Notices. All demands, notices, requests, consents and other communications required or permitted under this Agreement shall be in writing and shall be personally delivered or sent by facsimile machine (with a confirmation copy sent by one of the other methods authorized in this section), commercial (including Federal Express) or U.S. Postal Service overnight delivery service, or deposited with the U.S. Postal Service mailed first class, registered or certified mail, postage prepaid, as follows:

THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made and entered into as of this 28th day of April, 2003 by and among Pennsylvania Real Estate Investment Trust, a Pennsylvania business trust (the "Trust"), and each of those persons whose names are set forth on Exhibit A hereto (collectively, the "Holders," and each individually, a "Holder").

Background

On April 22, 2003, the Trust, PREIT Associates, L.P., a Delaware limited partnership (the "Operating Partnership"), certain of the Holders and certain other parties entered into that certain Contribution Agreement (the "Contribution Agreement"), which was joined in by the remainder Holder on April 23, 2003. Pursuant to the Contribution Agreement, on the date hereof (the "First Closing Date"), the Holders are acquiring an aggregate of 585,422 units (the "Initial Applicable Units") of Class B Limited Partner Interest ("Class B Units") in the Operating Partnership.

In connection with the execution of the Contribution Agreement, and as contemplated thereby, on the date hereof, the Operating Partnership, the Holders and certain other parties are also entering into that certain Call and Put Option Agreement (the "Call-Put Agreement"). Pursuant to the Call-Put Agreement, the Holders may acquire, on a subsequent date (the "Second Closing Date"), additional Class B Units (the "Additional Applicable Units" and, together with the Initial Applicable Units, the "Applicable Units").

As holders of Class B Units, the Holders have certain redemption rights under the terms and conditions of the First Amended and Restated Agreement of Limited Partnership of the Operating Partnership dated as of September 30, 1997 (as amended from time to time, the "Operating Partnership Agreement"). Under the Operating Partnership Agreement, a holder of Class B Units that has properly tendered Class B Units for redemption has the right to receive cash or, at the election of the Trust, shares of beneficial interest in the Trust, par value $1.00 per share ("Shares").

As a condition of consummating the transactions contemplated by the Contribution Agreement, the Holders have required that the Trust extend to them certain registration rights in respect of the Shares that they may be entitled to receive in connection with the redemption of the Applicable Units, all on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE II
REGISTRATION RIGHTS

Section 2.1 Registration of Registrable Securities.

(a) The Trust shall prepare and file with the SEC, and use its commercially reasonable efforts to cause to become effective, as soon as reasonably practicable following the First Closing Date, a registration statement on Form S-3 (or, if Form S-3 is not then available, on such form of registration statement as is then available to effect a registration of all of the Registrable Securities to be so registered) covering the resale of all of the Shares issuable in connection with the redemption of the Initial Applicable Units issued on the First Closing Date.

(b) In the event that any Additional Applicable Units are issued by the Operating Partnership pursuant to the Call-Put Agreement, then the Trust shall prepare and file with the SEC, and use its commercially reasonable efforts to cause to become effective, within six months following the Second Closing Date, a registration statement on Form S-3 (or, if Form S-3 is not then available, on such form of registration statement as is then available to effect a registration of all of the Registrable Securities to be so registered) covering the resale of all of the Shares issuable in connection with the redemption of the Additional Applicable Units issued on the Second Closing Date.

3

(c) Notwithstanding the foregoing provisions of this Section 2.1, but subject to Section 2.7(b), in the event that the Trust is required to prepare and file a registration statement covering Registrable Securities pursuant to paragraph (a) or (b) above, the Trust shall have the right, upon written notice to the Holders, to defer the filing or effectiveness of such registration statement for up to 90 days (the number of days of any such deferral being hereinafter referred to as the "Registration Deferral Period") if
(i) the Trust is, at such time, working on an underwritten public offering of its securities for the account of the Trust and is advised by its managing underwriter that such offering would in its opinion be materially adversely affected by such a filing; or (ii) the Trust determines reasonably and in good faith that the filing or effectiveness of such a registration statement, or the offering of Registrable Securities pursuant thereto, would require the disclosure of material non-public information, the disclosure of which at such time could reasonably be expected to have a material adverse effect on the business or affairs of the Trust or a material adverse effect on any proposal or plan by the Trust or any of its subsidiaries to engage in any extraordinary engagement or activity, including, without limitation, any material acquisition of assets or any merger, consolidation, tender offer or similar transaction.

Section 2.2 Obligations of the Trust. Whenever required under
Section 2.1 to effect the registration of any of the Registrable Securities, the Trust shall, as expeditiously as reasonably possible:

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use reasonable efforts to (i) cause such registration statement to become effective in order to permit the sale of the Registrable Securities by the Holders in accordance with the intended method or methods of distribution thereof described in such registration statement and (ii) maintain the effectiveness of such registration statement as to the Registrable Securities covered thereby until the earlier of (A) the date on which the Holders no longer hold any of the Registrable Securities covered thereby or any of the Applicable Units to which the Registrable Securities covered thereby relate, or (B) the date on which all of the Registrable Securities included in such registration statement have ceased to constitute Registrable Securities, after which the Trust may deregister such Registrable Securities;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in paragraph (a) above;

(c) furnish to the Holders such number of copies of the prospectus, including all amendments and supplements thereto, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

4

(d) comply in all material respects with the provisions of the Securities Act applicable to the Trust with respect to the disposition of all of the Registrable Securities covered by such registration statement in accordance with the intended method or methods of disposition by the Holders;

(e) use reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided, however, that the Trust shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

(f) (i) promptly notify the Holders, and, if requested, confirm such notification in writing, (A) when a prospectus or any prospectus supplement has been filed with the SEC and when the registration statement or any post-effective amendment thereto has been filed with and declared effective by the SEC, (B) of the issuance by the SEC of any stop order or the coming to its knowledge of the initiation of any proceedings for that purpose, (C) of the receipt by the Trust of any notification with respect to the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (D) of the occurrence of any event that requires the making of any changes to the registration statement or related prospectus so that such documents will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (E) of the Trust's determination that the filing of a post-effective amendment to the registration statement shall be necessary or appropriate; and (ii) upon the occurrence of any event of the kind described in clauses (B), (C) (but only with respect to the jurisdiction suspending qualification), (D) or (E), above, as promptly as practicable thereafter, take such action as shall be necessary to remedy such event to permit the Holders to continue to offer and dispose of the Registrable Securities, including, without limitation, preparing and filing with the SEC and furnishing to the Holders a supplement or amendment to such prospectus so that, as thereafter deliverable to the purchasers of the Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(g) make available to the Holders and any attorney, accountant or other agent or representative retained by the Holders (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of the Trust, as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Trust's officers, directors and employees to supply all information reasonably requested by any such Inspector in connection with such registration statement, subject, in each case, to such confidentiality agreements as the Trust shall reasonably request;

(h) use reasonable efforts to cause the Registrable Securities covered by such registration statement to be listed on the securities exchange or quoted on the quotation system on which similar securities issued by the Trust are then listed or quoted;

5

(i) otherwise use reasonable efforts to cooperate with the SEC and any other regulatory agencies and take all reasonable actions and execute and deliver or cause to be executed and delivered all documents reasonably necessary to effect and maintain the effectiveness of the registration of any Registrable Securities under this Agreement; and

(j) during the period when a prospectus is required to be delivered under the Securities Act, promptly file all documents required to be filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act.

Section 2.3 Obligations of the Holder.

(a) It shall be a condition precedent to the obligation of the Trust to register the Registrable Securities of any Holder pursuant to Section 2.1 that such Holder shall furnish to the Trust, upon request, such information regarding itself, its Registrable Securities and the intended method of disposition of such Registrable Securities as shall be reasonably required to effect the registration of such Registrable Securities.

(b) Each Holder shall (i) offer to sell or otherwise distribute the Registrable Securities in reliance upon a registration contemplated by this Agreement only after a registration statement shall have been filed with the SEC, (ii) sell or otherwise distribute the Registrable Securities in reliance upon a registration only after a registration statement has been filed and declared effective under the Securities Act, (iii) upon the receipt of any notice from the Trust of the occurrence of any event of the kind described in Section 2.2(f)(i)(B), (C) (but only with respect to the jurisdiction suspending qualification), (D) or (E), forthwith discontinue any offer and disposition of the Registrable Securities pursuant to the registration statement covering such Registrable Securities until such time as the Trust shall have remedied such event or prepared an appropriate amendment or supplement to the prospectus covering such Registrable Securities and, if so directed by the Trust, deliver to the Trust all copies of the defective prospectus covering such Registrable Securities that are then in such Holder's possession or control, (iv) distribute the Registrable Securities in reliance upon a registration contemplated by this Agreement only in accordance with the manner of distribution contemplated by the prospectus and (v) report to the Trust distributions made by such Holder of Registrable Securities pursuant to the prospectus.

(c) During any period that a registration statement filed pursuant to this Agreement shall remain effective, no Holder shall (i) effect any stabilization transactions or engage in any stabilization activity in connection with the Shares or other equity securities of the Trust in contravention of Regulation M under the Exchange Act, or (ii) permit any "Affiliated Purchaser" (as that term is defined in Regulation M under the Exchange Act) to bid for or purchase for any account in which such Holder has a beneficial interest, or attempt to induce any other person to purchase, any Shares or other equity securities of the Trust in contravention of Regulation M under the Exchange Act.

(d) If the Trust is issuing or selling equity securities to the public in an underwritten offering, and the managing underwriter or underwriters for such underwritten offering so request, the Holders shall refrain from effecting any public sale or distribution of Registrable Securities or any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144 (or any similar provision then in force) under the Securities Act, for a period commencing on the tenth (10th) day prior to the date such underwritten offering commences (such offering being deemed to commence for this purpose on the later of the effective date for the registration statement for such offering or, if applicable, the date of the prospectus supplement for such offering) and ending 90 days after such underwritten offering commences; provided that all officers and directors of the Trust and holders of at least five percent (5%) of the Trust's Shares enter into similar agreements and subject to any concession (such as early release from such lock-up) granted to any such officers, directors or holders.

6

Section 2.4 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any registration shall be borne by the Trust. All Selling Expenses incurred in connection with any such registrations shall be borne by the Holders.

Section 2.5 Indemnification. With respect to Registrable Securities that are included in a registration statement under Section 2.1:

(a) To the extent permitted by law, the Trust shall indemnify and hold harmless the Holders, their respective Affiliates, partners, officers, directors, stockholders and agents, and any other person who controls any of the foregoing within the meaning of the Securities Act or the Exchange Act (collectively, the "Holder Indemnitees"), against any losses, claims, damages, expenses, judgments or liabilities (joint or several) to which any Holder Indemnitee may become subject, including any amount paid in settlement of any litigation commenced or threatened (unless such settlement is effected without the consent of the Trust, which consent shall not be unreasonably withheld), and shall promptly reimburse each Holder Indemnitee, as and when incurred, for any legal or other expenses incurred by such Holder Indemnitee in connection with investigating any claims and defending any actions, insofar as such losses, claims, damages, expenses, judgments or liabilities (or actions in respect thereof) shall arise out of or shall be based upon (i) any violation or alleged violation by the Trust of the Securities Act, the Exchange Act or any other securities laws, relating to action taken or action or inaction required of the Trust in connection with such offering, (ii) any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any final prospectus included therein) relating to the offering and sale of the Registrable Securities, or any amendment thereof or supplement thereto, or in any document incorporated by reference therein, or (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the indemnity agreement contained in this Section 2.5(a)(ii) and (iii) shall not apply to a Holder in any such case to the extent that any such loss, claim, damage, expense, judgment, liability or action arises out of or is based upon any untrue statement or alleged untrue statement, or any omission or alleged omission, if such statement or omission shall have been (A) made in reliance upon and in conformity with information furnished to the Trust in writing by or on behalf of such Holder Indemnitee for inclusion in such registration statement (including any final prospectus contained therein), or any amendment thereof or supplement thereto, or (B) made in any preliminary prospectus and the final prospectus shall have corrected such statement or omission and a copy of such final prospectus shall have been delivered to such Holder Indemnitee prior to the time such final prospectus is required to be delivered by such Holder Indemnitee under applicable law and such loss, claim, damage, expense, judgment, liability or action arises out of such Holder's failure to deliver such final prospectus in compliance with applicable law.

7

(b) To the extent permitted by law, each Holder shall indemnify and hold harmless the Trust, each of its officers and trustees, each person, if any, who controls the Trust within the meaning of the Securities Act or the Exchange Act and any other Holder Indemnitee (collectively, the "Trust Indemnitees"), against any losses, claims, damages, expenses, judgments or liabilities (joint or several) to which any Trust Indemnitee may become subject, including any amount paid in settlement of any litigation commenced or threatened (unless such settlement is effected without the consent of such Holder, which consent shall not be unreasonably withheld), and shall promptly reimburse each Trust Indemnitee, as and when incurred, for any legal or other expenses incurred by such Trust Indemnitee in connection with investigating any claims and defending any actions, insofar as such losses, claims, damages, expenses, judgments or liabilities (or actions in respect thereto) shall arise out of or shall be based upon (i) any violation by such Holder of Section 5 of the Securities Act in connection with such offering (other than as a result of such a violation by the Trust or any other person other than such Holder), (ii) any untrue statement or alleged untrue statement of a material fact contained in the registration statement (or in any final prospectus included therein) relating to the offering and sale of the Registrable Securities, or any amendment thereof or supplement thereto, or in any document incorporated by reference therein, or (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the indemnity agreement contained in this
Section 2.5(b)(ii) and (iii) shall only apply in any such case (A) to the extent that any such loss, claim, damage, expense, judgment, liability or action arises out of or is based upon an untrue statement contained in, or a material fact omitted from, information furnished to the Trust in writing by or on behalf of such Holder for inclusion in the registration statement (or in any final prospectus included therein), and (B) if any such untrue statement or material omission is incorporated by the Trust in any preliminary prospectus, to the extent that such statement or omission shall not have been corrected in writing by or on behalf of such Holder prior to the time the final prospectus is required to be delivered by the Trust under applicable law.

(c) Promptly after receipt by an indemnified party under this
Section 2.5 of notice of the commencement of any action (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.5, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.5 to the extent of such prejudice, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.5.

8

(d) If the indemnification provided for in this Section 2.5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the circumstances that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The obligations of the Trust and the Holders under this
Section 2.5 shall survive completion of any offering of Registrable Securities in a registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

Section 2.6 Assignment of Registration Rights. The rights to cause the Trust to register Registrable Securities pursuant to this Article II may be assigned by a Holder to a transferee or assignee of Registrable Securities or Applicable Units that (a) is an Affiliate of such Holder, or (b) is a member of such Holder's immediate family or is a trust for the benefit of such Holder or a member of such Holder's immediate family; provided, however, that (i) within ten days after such transfer, the transferring Holder furnishes to the Trust written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned, and (ii) such transferee agrees to be subject to all restrictions set forth in this Agreement.

Section 2.7 Information Blackout.

(a) At any time when a registration statement covering Registrable Securities is effective, upon written notice from the Trust to the Holders that the Trust has determined reasonably and in good faith that the sale of Registrable Securities pursuant to the registration statement would require disclosure of material non-public information, the disclosure of which at such time could reasonably be expected to have a material adverse effect on the business or affairs of the Trust or a material adverse effect on any proposal or plan by the Trust or any of its subsidiaries to engage in any extraordinary engagement or activity, including, without limitation, any material acquisition of assets or any merger, consolidation, tender offer or similar transaction, the Holders shall suspend sales of the Registrable Securities pursuant to the registration statement until the earlier of (i) 45 days after the Trust notifies the Holders of such good faith determination, or (ii) such time as the Trust notifies the Holders that such material information has been disclosed to the public or has ceased to be material or that sales pursuant to the registration statement may otherwise be resumed (the number of days from such suspension of sales by the Holders until the day when such sales may be resumed hereunder being hereinafter referred to as the "Sales Blackout Period").

9

(b) In no event shall the Trust be permitted to impose Registration Deferral Periods or Sales Blackout Periods that, collectively, extend for more than 90 days in any given 12 month period.

Section 2.8 Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations under the Securities Act that may at any time permit the sale of the Registrable Shares to the public without registration, at all times that the Trust is subject to the reporting requirements of the Exchange Act, the Trust shall use its reasonable efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the SEC, in a timely manner, all reports and other documents required of the Trust under the Securities Act and the Exchange Act; and

(c) so long as a Holder owns any Registrable Securities (or Applicable Units), furnish to such Holder forthwith upon request (i) a written statement by the Trust as to its compliance with the reporting requirements of Rule 144 and of the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Trust, and (iii) such other reports and documents of the Trust as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any such securities without registration.

ARTICLE III
MISCELLANEOUS

Section 3.1 Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania (without giving effect to any conflicts or choice of law provisions that would cause the application of the domestic substantive laws of any other jurisdiction).

Section 3.2 Cumulative Remedies; Failure to Pursue Remedies. The rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy by any party shall not preclude or waive its right to use any or all other remedies. Said rights and remedies are given in addition to any other rights the parties may have by law, statute, ordinance or otherwise. Except where a time period is specified, no delay on the part of any party in the exercise of any right, power, privilege or remedy hereunder shall operate as a waiver thereof, nor shall any exercise or partial exercise of any such right, power, privilege or remedy preclude any further exercise thereof or the exercise of any other right, power, privilege or remedy.

10

Section 3.3 Amendment and Waiver. Except as otherwise expressly provided herein, no provision of this Agreement may be amended, modified or waived except upon the written consent of the Trust and the Holders who own greater than fifty percent (50%) of the Registrable Securities (including, for this purpose, Applicable Units) then outstanding owned by all Holders. Notwithstanding the foregoing, the Trust may amend Exhibit A hereto to reflect dispositions of Registrable Securities by Holders (including the addition of new Holders as a result of any permitted assignment of the rights granted hereunder in accordance with Section 2.6) without obtaining the written consent of the Holders. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Section 3.4 Notices. All demands, notices, requests, consents and other communications required or permitted under this Agreement shall be in writing and shall be personally delivered or sent by facsimile machine (with a confirmation copy sent by one of the other methods authorized in this section), commercial (including Federal Express) or U.S. Postal Service overnight delivery service, or deposited with the U.S. Postal Service mailed first class, registered or certified mail, postage prepaid, as follows:

WHEREAS, in light of such pending sale of the Property, Owner and Agent desire to terminate the Management Agreement pursuant to the terms hereof.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Owner and Agent agree as follows:

1. The Management Agreement is terminated effective as of the date Owner transfers title to the Property to Buyer.

2. Notwithstanding the termination of the Management Agreement, the parties shall comply with all obligations contained in the Management Agreement that are intended to survive such termination, including without limitation Sections 3.5, 7.3 and 7.4 thereof; provided, however, the aggregate commission that will be due Agent as result of the closing of the sale of the Property to Buyer is Two Million Dollars ($2,000,000.00), which commission will be paid at closing.

The Agent will be and will continue throughout the term of this Agreement to be an Equal Opportunity Employer.

The Agent shall notify the Owner of the necessity for, the nature of, and the cost of any such emergency repairs or compliance.

In the event state law requires tenant security deposits be held in a separate account, such account shall be established by the Agent as approved by the Owner.

The Owner or the Owner's designated representative will be a signatory on the Bank Account, but need not co-sign each check.

(h) collect such rent and other charges from tenants in a timely manner and to pursue Owner's legal remedies for non-payment of same, including the termination of leases for tenants in default by the institution of legal action.

The fees for all such legal services shall be paid for by Owner, including (i) negotiation of leases, including department store leases and reciprocal easement agreements; (ii) preparation and negotiations of construction contracts for renovations of the Premises; (iii) suits to enforce leases; (iv) bankruptcy claims involving tenants; (v) negotiations with labor unions; (vi) environmental matters and (vii) any other legal action approved by Owner.

Agent may deduct the amount to be reimbursed from the Bank Account.

Such compliance shall be undertaken in the

-6-

name of Owner, and be at Owner's expense. Agent shall give prompt written notice to Owner of any violation or notice of alleged violation of such laws and Agent shall not bear responsibility for failure of the Premises or the operation thereof to comply with such laws unless Agent has committed gross negligence or a willful act or omission in the performance of its obligations under this Agreement.

Prior to Owner's default or the termination of this Agreement the Owner shall, at any time, have the right to require the transfer to the Owner of any funds in the Bank Account considered by the Owner and Agent to be in excess of an amount reasonably required by the Agent for disbursement purposes in connection with the Premises.

Losses caused by failure to exercise reasonable diligence shall be borne by Agent.

2.4 The Agent shall prepare and submit to the Owner a proposed operating and capital budget for the promotion, operation, repair and maintenance of the Premises for each calendar year. Preliminary and final budgets will be due ninety (90) and sixty (60) days, respectively, prior to the end of each calendar year. Such budgets shall be prepared on a cash basis showing a month by month projection of income and expense and capital expenditures and shall be accompanied by proposed leasing guidelines for the next ensuing calendar year which shall contain a brief narrative description of the anticipated market, a projection of cash flow for such year, listing expiring leases for the next following year as well as project ranges of rental rates and terms for new or renewal leases, estimates of concessions to tenants and of cost estimates of alterations for space to be leased. The annual budget shall be deemed approved unless Agent receives written notification of disapproval within thirty (30) days after the date such budget was tendered to Owner for approval; Owner shall

-7-

have the right to disapprove line items in such budget or the entire budget. In the event of a line item disapproval, all portions of the budget not disapproved shall automatically be deemed approved. In the event of such disapproval of the budget or any specific line items thereof, the parties will promptly meet and resolve such differences and Agent will promptly thereafter resubmit a revised budget to Owner who shall have an additional ten (10) days to approve or disapprove the same and such procedure shall continue until the budget has been approved. If Owner shall fail to disapprove the revised budget within ten (10) days of receipt, the same shall be deemed approved.

Such budgets and all other financial reporting to be prepared by Agent shall be prepared using Agent's then standard format and software. Agent shall not be obligated to use any other financial format or software unless same is satisfactory to Agent, Owner purchases same for Agent and Owner pays all of the training expenses for Agent's employees relating to such software.

The Agent shall promptly notify the Owner if the Agent reasonably anticipates any such line item exceeding one hundred ten (110%) percent of the amount therefor in the approved budget.

2.5 Agent agrees, for itself and all persons retained or employed by Agent in performing its services, to hold in confidence and not to use or disclose to others any confidential or proprietary information of Owner heretofore or hereafter disclosed to Agent including, but not limited to, any data, information, plans, programs, processes, costs, operations or tenants which may come within the knowledge of Agent in the performance of or as a result of its services, except where Owner specifically authorizes Agent to disclose any of the foregoing to others or such disclosure reasonably results from the performance of Agent's duties hereunder or is required to be disclosed pursuant to litigation.

2.6 The Agent agrees to use its best efforts to have the Premises rented to desirable tenants, satisfactory to the Owner considering the nature of the Premises, and in connection therewith to negotiate business terms for relocation and/or expansions, new leases and renewals of leases at appropriate times, it being understood that all inquiries to the Owner with respect to leasing any portion of the Premises shall be referred to the Agent. At least once per year Owner and Agent shall meet and mutually develop a "leasing game plan" for the ensuing calendar year which game plan shall specify projected vacancies, projected rentals and other pertinent terms of new leases or lease renewals, costs to be incurred in obtaining tenants and other relevant matters. Owner hereby authorizes Agent to implement the approved leasing game plan and to negotiate and execute leases in accordance therewith and confirms that any leases so executed shall be deemed approved by Owner and Owner shall pay Agent the leasing commission set forth in this Agreement with respect to each lease executed by a tenant consistent with the leasing game plan. Agent is hereby

-8-

given the exclusive right to lease the Premises on behalf of Owner and Owner shall pay to Agent the leasing commission set forth in Exhibit B regardless of who may negotiate the same, including Owner. All leases and renewals shall be prepared by the Agent on the Agent's form lease, and such leases shall either be executed by Agent on behalf of Owner or, at Agent's option shall be executed by the Owner. The Agent agrees it will observe the specific leasing guidelines, if any, set forth in the approved budget or otherwise made known to the Agent in writing by the Owner. In the event the Agent shall have a prospective tenant reference from another property in the local market area where the Premises are located in which the Agent has a beneficial interest or which the Agent manages, the Agent shall declare its potential conflict of interest to the Owner, and the Owner shall determine if negotiations shall be undertaken by the Agent, the Owner, or a third party appointed by the Owner. References of prospective tenants, as well as their varying use requirements, shall be investigated by the Agent.

(b) Unless expressly provided, Agent shall not be responsible or obligated to advance its own funds for any purpose in the performance of Agent's duties under this Agreement.

However, such a standard shall not impose additional duties or obligations on Agent not set forth in this Agreement, such as, by way of example, an obligation to advance Agent's funds or to commence litigation against third parties, or to take extraordinary actions or to perform services not customarily provided by managers of comparable buildings in the local geographic area. Nothing in this Agreement shall require Agent to perform the obligations of others or exercise any efforts (other than reasonable efforts) to cause them to perform such obligations.

-9-

(e) Everything done by Agent in the performance of its obligations under this Agreement and all expenses incurred pursuant hereto shall be for and on behalf of Owner and for its account and at its expense. Except as otherwise expressly provided herein, all debts and liabilities incurred to third parties in accordance with the annual budget and in the ordinary course of business of managing the Premises are and shall be obligations of Owner, and Agent shall not be liable for any such obligations by reason of its management, supervision or operation of the Premises for Owner.

Such fee shall include Agent's fee for any due diligence work required to accomplish such refinancing and/or sale.

3.6 Owner agrees to make available to Agent, free of charge, an on-site office to be utilized in connection with Agent's leasing of the Premises. In addition, Owner shall reimburse Agent monthly for all travel expenses, leasing and marketing materials, demographic and marketing studies signage and advertising incurred by Agent during the performance of its obligations under this Agreement.

7.2 In the event a party hereto (the "Defaulting Party") (a) materially defaults in the performance of its obligations under this Agreement and such default remains uncured for more than twenty (20) days' after such party's receipt of written notice from the other party hereto, except for defaults not susceptible to cure within twenty (20) days, provided as to such defaults the Defaulting Party commences to cure within such twenty (20) day period and diligently prosecutes each cure; or (b) makes an assignment for the benefit of creditors; or (c) has appointed a receiver, liquidator or trustee of its property; or (d) is adjudicated to be a bankrupt or insolvent; or (e) has filed by or against it any petition for the bankruptcy, reorganization or arrangement of the Defaulting Party or, if such appointment, adjudication or petition be involuntary and not consented to by the Defaulting Party and fails to proceed diligently to have the same discharged or dismissed, then the other party hereto may forthwith terminate this Agreement upon giving ten (10) days' written notice to the Defaulting Party.

7.3 This Agreement shall terminate at the election of the Owner upon thirty (30) days' written notice to the Agent if the Premises are sold by the Owner to a non-affiliated third party purchaser or automatically if the Premises were

-14-

acquired by the owner on foreclosure of a mortgage and are subsequently redeemed. In the event the Premises are sold by the Owner to a non-affiliated third party purchaser and this Agreement is not thereby terminated by the Owner, the Agent shall have the right to terminate this Agreement upon sixty (60) days prior written notice. The Term "non-affiliate" as used herein shall mean any entity which is not an "affiliate" as such term is defined in Section 8.1 hereof. Upon termination of this Agreement for any reason, the Agent shall deliver the following to the Owner or the Owner's duly appointed agent on or before thirty (30) days following the termination date:

(a) A final accounting, reflecting the balance of income and expense for the Premises as of the date of termination;

7.4 Notwithstanding termination of this Agreement by the Owner, the Owner shall reimburse the Agent within thirty (30) days after receipt of documents from the Agent supporting such expenses, for all sums as may be necessary to satisfy known obligations which the Agent has incurred for the Owner's accounts as authorized under this Agreement, including all severance payments relating to employees at the Premises who are not retained by Owner. In addition, after any termination by the Owner, the Owner and the Agent will as promptly as possible settle any outstanding balances with each other and render final accounts as to any items overlooked or treated incorrectly in any previous settlement, accounting or remittance. Upon any termination of this Agreement, Agent shall assign to Owner or Owner's nominee all service, supply and other contracts and agreements pertaining to the Premises entered into by Agent in accordance with this Agreement and thereupon Owner shall be fully responsible and liable for the performance of all obligations of Agent under all such contracts and agreements occurring after the date of such assignment and Agent shall have no further responsibility or liability with respect thereto. Owner shall indemnify and hold Agent harmless with respect to all such contracts. Any termination permitted hereunder shall not prejudice Agent's right to receive amounts to which Agent is entitled hereunder on account of services rendered by Agent prior to said termination.

-15-

does in good faith advance its own funds for purposes authorized herein or for emergency repairs, the Owner shall promptly reimburse the Agent without interest upon receipt of proper documentation.

Subject to the terms and conditions of this Agreement, during the period from the Effective Date to but excluding the Revolving Credit Termination Date, the Borrower may borrow, repay and reborrow Revolving Loans.

(b) Term Loans. Subject to the terms and conditions hereof, during the period from the Effective Date to but excluding the Term Loan Facility Expiration Date, each Lender severally and not jointly agrees to make Term Loans to the Borrower in an aggregate principal amount at any one time outstanding up to, but not exceeding, the amount of such Lender's Term Commitment; provided, however, the aggregate amount of Term Loans advanced to finance the acquisition of a given Rouse Property shall not exceed the amount set forth with respect to such Property on Schedule 2.1.(b). Once repaid, the principal amount of a Term Loan may not be reborrowed.

(c) Requesting Loans. The Borrower shall give the Agent notice pursuant to a Notice of Borrowing of each borrowing of Loans.

(i) during such periods as such Loan is a Base Rate Loan, at the Base Rate (as in effect from time to time); and

(ii) during such periods as such Loan is a LIBOR Loan, at LIBOR for such Loan for the Interest Period therefor (from the first day to, but excluding, the last day of such Interest Period), plus the Applicable Margin for such Loan.

Notwithstanding the foregoing, during the continuance of an Event of Default, the Borrower shall pay to the Agent for the account of each Lender interest at the Post-Default Rate on the outstanding principal amount of any Loan made by such Lender and on any other amount payable by the Borrower hereunder or under the Notes held by such Lender to or for the account of such Lender (including without limitation, accrued but unpaid interest to the extent permitted under Applicable Law).

In the event the maturity of the Obligations hereunder occurs or is accelerated pursuant to Section 9.2., this Section shall apply only to payments overdue prior to the time of such acceleration. This Section shall not be deemed to be a waiver of the Lenders' right to accelerate payment of any of the Obligations as permitted under the terms of this Agreement.

Section 2.6. Prepayments.

(a) Optional. Subject to Section 4.4., the Borrower may prepay any Loan at any time without premium or penalty. The Borrower shall give the Agent at least three (3) Business Days prior written notice of the prepayment of any Loan.

So long as no Event of Default shall have occurred and be continuing, the Borrower may on any Business Day, with respect to any LIBOR Loan, elect to maintain such LIBOR Loan or any portion thereof as a LIBOR Loan by selecting a new Interest Period for such LIBOR Loan. Each new Interest Period selected under this Section shall commence on the last day of the immediately preceding Interest Period. Each selection of a new Interest Period shall be made by the Borrower giving to the Agent a Notice of Continuation not later than 9:00 a.m. on the third Business Day prior to the date of any such Continuation. Such notice by the Borrower of a Continuation shall be by telephone or telecopy, confirmed immediately in writing if by telephone, in the form of a Notice of Continuation, specifying (a) the proposed date of such Continuation, (b) the LIBOR Loan and portion thereof subject to such Continuation and (c) the duration of the selected Interest Period, all of which shall be specified in such manner as is necessary to comply with all limitations on Loans outstanding hereunder.

Each such Notice of Conversion shall be given not later than 9:00

The Agent shall forward to each Lender a copy of any such extension request delivered to the Agent promptly upon receipt thereof.

Section 3.3. Sharing of Payments, Etc.

If a Lender shall obtain payment of any principal of, or interest on, any Loan made by it to the Borrower under this Agreement, or shall obtain payment on any other Obligation owing by the Borrower or a Loan Party through the exercise of any right of set-off, banker's lien or counterclaim or similar right or otherwise or through voluntary prepayments directly to a Lender or other payments made by the Borrower or other Loan Party to a Lender not in accordance with the terms of this Agreement and such payment should be distributed to the Lenders pro rata in accordance with Section 3.2. or Section 9.5., as applicable, such Lender shall promptly purchase from the other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans made by the other Lenders or other Obligations owed to such other Lenders in such amounts, pay such amounts to the other Lenders and make such other adjustments from time to time as shall be equitable, so that all the Lenders shall share the benefit of such payment (net of any reasonable expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with Section 3.2. or Section 9.5. To such end, all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans or other Obligations owed to such other Lenders may exercise all rights of set-off, banker's lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower.

-7-

Section 3.4. Several Obligations.

No Lender shall be responsible for the failure of any other Lender to make a Loan or to perform any other obligation to be made or performed by such other Lender hereunder, and the failure of any Lender to make a Loan or to perform any other obligation to be made or performed by it hereunder shall not relieve the obligation of any other Lender to make any Loan or to perform any other obligation to be made or performed by such other Lender.

Section 3.5. Minimum Amounts.

(a) Borrowings. Each borrowing of Base Rate Loans shall be in an aggregate minimum amount of $500,000 and integral multiples of $25,000 in excess thereof. Each borrowing and Continuation of, and each Conversion of Base Rate Loans into, LIBOR Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $25,000 in excess of that amount.

Section 3.7. Computations.

Unless otherwise expressly set forth herein, any accrued interest on any Loan, any Fees or other Obligations due hereunder shall be computed on the basis of a year of 360 days and the actual number of days elapsed.

Section 3.8. Usury.

In no event shall the amount of interest due or payable on the Loans or other Obligations exceed the maximum rate of interest allowed by Applicable Law and, if any such payment is paid by the Borrower or received by any Lender, then such excess sum shall be credited as a payment of principal, unless the Borrower shall notify the respective Lender in writing that the Borrower elects to have such excess sum returned to it forthwith. It is the express intent of the parties hereto that the Borrower not pay and the Lenders receive, directly or indirectly, in any manner whatsoever, interest in excess of that which may be lawfully paid by the Borrower under Applicable Law. The parties hereto hereby agree and stipulate that the only charge imposed upon the Borrower for the use of money in connection with this Agreement is and shall be the interest described in Sections 2.2.(a)(i) and (ii). Notwithstanding the foregoing, the parties hereto further agree and stipulate that all agency fees, syndication fees, facility fees, underwriting fees, default charges, late charges, funding or "breakage" charges, increased cost charges, attorneys' fees and reimbursement for costs and expenses paid by the Agent or any Lender to third parties or for damages incurred by the Agent or any Lender, are charges made to compensate the Agent or any such Lender for underwriting or administrative services and costs or losses performed or incurred, and to be performed or incurred, by the Agent and the Lenders in connection with this Agreement.

Section 3.9. Statements of Account.

The Agent will account to the Borrower monthly with a statement of Loans, accrued interest and Fees, charges and payments made pursuant to this Agreement and the other Loan Documents, and such account rendered by the Agent shall be deemed conclusive upon the Borrower absent manifest error. The failure of the Agent to deliver such a statement of accounts shall not relieve or discharge the Borrower from any of its obligations hereunder.

-9-

Section 3.10. Defaulting Lenders.

If for any reason any Lender (a "Defaulting Lender") shall fail or refuse to perform any of its obligations under this Agreement or any other Loan Document to which it is a party within the time period specified for performance of such obligation or, if no time period is specified, if such failure or refusal continues for a period of two Business Days after notice from the Agent, then, in addition to the rights and remedies that may be available to the Agent or the Borrower under this Agreement or Applicable Law, such Defaulting Lender's right to participate in the administration of the Loans, this Agreement and the other Loan Documents, including without limitation, any right to vote in respect of, to consent to or to direct any action or inaction of the Agent or to be taken into account in the calculation of the Requisite Lenders, shall be suspended during the pendency of such failure or refusal. If a Lender is a Defaulting Lender because it has failed to make timely payment to the Agent of any amount required to be paid to the Agent hereunder (without giving effect to any notice or cure periods), in addition to other rights and remedies which the Agent or the Borrower may have under the immediately preceding provisions or otherwise, the Agent shall be entitled (a) to collect interest from such Defaulting Lender on such delinquent payment for the period from the date on which the payment was due until the date on which the payment is made at the Federal Funds Rate, (b) to withhold or setoff and to apply in satisfaction of the defaulted payment and any related interest, any amounts otherwise payable to such Defaulting Lender under this Agreement or any other Loan Document and (c) to bring an action or suit against such Defaulting Lender in a court of competent jurisdiction to recover the defaulted amount and any related interest. Any amounts received by the Agent in respect of a Defaulting Lender's Loans shall not be paid to such Defaulting Lender and shall be held uninvested by the Agent until such Defaulting Lender cures its default.

Section 3.11. Taxes.

(a) Taxes Generally. Except as provided in subsection (c) of this Section, all payments by the Borrower of principal of, and interest on, the Loans and all other Obligations shall be made free and clear of and without deduction for any present or future excise, stamp or other taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding (i) franchise taxes, (ii) any taxes (other than withholding taxes) that would not be imposed but for a connection between the Agent or a Lender and the jurisdiction imposing such taxes (other than a connection arising solely by virtue of the activities of the Agent or such Lender pursuant to or in respect of this Agreement or any other Loan Document), (iii) any taxes imposed on or measured by any Lender's assets, income, receipts or branch profits and (iv) any taxes arising after the Agreement Date solely as a result of or attributable to a Lender changing its designated Lending Office after the date such Lender becomes a party hereto (such non-excluded items being collectively called "Taxes"). If any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any Applicable Law, then the Borrower will:

(i) pay directly to the relevant Governmental Authority the full amount required to be so withheld or deducted;

(ii) promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing such payment to such Governmental Authority; and

-10-

(iii) pay to the Agent for its account or the account of the applicable Lender, as the case may be, such additional amount or amounts as is necessary to ensure that the net amount actually received by the Agent or such Lender will equal the full amount that the Agent or such Lender would have received had no such withholding or deduction been required.

(b) Tax Indemnification. If the Borrower fails to pay any Taxes when due to the appropriate Governmental Authority or fails to remit to the Agent, for its account or the account of the respective Lender, as the case may be, the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and the Lenders for any incremental Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. For purposes of this Section, a distribution hereunder by the Agent or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower.

(c) Tax Forms. Prior to the date that any Lender or Participant organized under the laws of a jurisdiction outside the United States of America becomes a party hereto, such Person shall deliver to the Borrower and the Agent such certificates, documents or other evidence, as required by the Internal Revenue Code or Treasury Regulations issued pursuant thereto (including Internal Revenue Service Forms W-8ECI and W-8BEN, as applicable, or appropriate successor forms), properly completed, currently effective and duly executed by such Lender or participant establishing that payments to it hereunder and under the Notes are (i) not subject to United States Federal backup withholding tax and (ii) not subject to United States Federal withholding tax under the Code. Each Lender shall (x) deliver further copies of such forms or other appropriate certifications on or before the date that any such forms expire or become obsolete and after the occurrence of any event requiring a change in the most recent form delivered to the Borrower and (y) obtain such extensions of the time for filing, and renew such forms and certifications thereof as may be reasonably requested by the Borrower or the Agent. The Borrower shall not be required to pay any amount pursuant to last sentence of subsection (a) above to any Lender or Participant that is organized under the laws of a jurisdiction outside of the United States of America or the Agent, if it is organized under the laws of a jurisdiction outside of the United States of America, if such Lender, Participant or the Agent, as applicable, fails to comply with the requirements of this subsection nor shall the Borrower be precluded from deducting any applicable withholding taxes in such case. If any such Lender or Participant fails to deliver the above forms or other documentation, then the Agent may withhold from such payment to such Lender such amounts as are required by the Code. If any Governmental Authority asserts that the Agent did not properly withhold or backup withhold, as the case may be, any tax or other amount from payments made to or for the account of any Lender, such Lender shall indemnify the Agent therefor, including all penalties and interest, any taxes imposed by any jurisdiction on the amounts payable to the Agent under this Section, and costs and expenses (including all fees and disbursements of any law firm or other external counsel and the allocated cost of internal legal services and all disbursements of internal counsel) of the Agent. The obligation of the Lenders under this Section shall survive the termination of the Commitments, repayment of all Obligations and the resignation or replacement of the Agent.

ARTICLE IV. YIELD PROTECTION, ETC.

Section 4.1. Additional Costs; Capital Adequacy.

(a) Additional Costs. The Borrower shall promptly pay to the Agent for the account of a Lender from time to time such amounts as such Lender may reasonably determine to be necessary to compensate such Lender for any costs incurred by such Lender that it determines are attributable to its making or maintaining of any LIBOR Loans or its obligation to make any LIBOR Loans hereunder, any reduction in any amount receivable by such Lender under this Agreement or any of the other Loan Documents in respect of any of such Loans or such obligation or the maintenance by such Lender of capital in respect of its Loans or its Commitments (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any Regulatory Change that: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any of the other Loan Documents in respect of any of such Loans or its Commitments (other than taxes imposed on or measured by the overall net income of such Lender or of its Lending Office for any of such Loans by the jurisdiction in which such Lender has its principal office or such Lending Office); or (ii) imposes or modifies any reserve, special deposit or similar requirements (including without limitation, Regulation D of the Board of Governors of the Federal Reserve System or other similar reserve requirement applicable to any other category of liabilities or category of extensions of credit or other assets by reference to which the interest rate on LIBOR Loans is determined) relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, or other credit extended by, or any other acquisition of funds by such Lender (or its parent corporation), or any commitment of such Lender (including, without limitation, the Commitments of such Lender hereunder); or (iii) has or would have the effect of reducing the rate of return on capital of such Lender to a level below that which such Lender could have achieved but for such Regulatory Change (taking into consideration such Lender's policies with respect to capital adequacy).

(b) Lender's Suspension of LIBOR Loans. Without limiting the effect of the provisions of the immediately preceding subsection (a), if by reason of any Regulatory Change, any Lender either (i) incurs Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Lender that includes deposits by reference to which the interest rate on LIBOR Loans is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lender that includes LIBOR Loans or (ii) becomes subject to restrictions on the amount of such a category of liabilities or assets that it may hold, then, if such Lender so elects by notice to the Borrower (with a copy to the Agent), the obligation of such Lender to make or Continue, or to Convert any other Type of Loans into, LIBOR Loans hereunder shall be suspended until such Regulatory Change ceases to be in effect (in which case the provisions of Section 4.5. shall apply).

-12-

(c) Notification and Determination of Additional Costs. Each of the Agent and each Lender agrees to notify the Borrower of any event occurring after the Agreement Date entitling the Agent or such Lender to compensation under any of the preceding subsections of this Section as promptly as practicable; provided, however, the failure of the Agent or any Lender to give such notice shall not release the Borrower from any of its obligations hereunder. The Agent and or such Lender agrees to furnish to the Borrower (and in the case of a Lender to the Agent as well) a certificate setting forth the basis and amount of each request by the Agent or such Lender for compensation under this Section. Determinations by the Agent or any Lender of the effect of any Regulatory Change shall be conclusive absent manifest error, provided that such determinations are made on a reasonable basis and in good faith.

Section 4.2. Suspension of LIBOR Loans.

Anything herein to the contrary notwithstanding, if, on or prior to the determination of LIBOR for any Interest Period: (a) the Agent determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the LIBOR for such Interest Period or (b) the Agent determines (which determination shall be conclusive) that LIBOR will not adequately and fairly reflect the cost to the Lenders of making or maintaining LIBOR Loans for such Interest Period; then the Agent shall give the Borrower and each Lender prompt notice thereof, and, so long as such condition remains in effect, the Lenders shall be under no obligation to, and shall not, make additional LIBOR Loans, Continue LIBOR Loans or Convert Loans into LIBOR Loans and the Borrower shall, on the last day of each current Interest Period for each outstanding LIBOR Loan, either repay such Loan or Convert such Loan into a Base Rate Loan in accordance with Section 4.5.

Section 4.3. Illegality.

Notwithstanding any other provision of this Agreement, if it becomes unlawful for any Lender to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof (with a copy to the Agent) and such Lender's obligation to make or Continue, or to Convert Loans of any other Type into, LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 4.5. shall be applicable).

Section 4.4. Compensation.

The Borrower shall pay to the Agent for the account of each Lender, upon the request of such Lender through the Agent, such amount or amounts as shall be sufficient (in the reasonable opinion of such Lender) to compensate it for any loss, cost or expense that such Lender determines is attributable to:
(a) any payment or prepayment (whether mandatory or optional) of a LIBOR Loan, or Conversion of a LIBOR Loan, made by such Lender for any reason (including, without limitation, acceleration) on a date other than the last day of the Interest Period for such Loan or (b) any failure by the Borrower for any reason (including, without limitation, the failure of any of the applicable conditions precedent specified in Article V. to be satisfied) to borrow a LIBOR Loan from such Lender on the date for such borrowing, or to Convert a Base Rate Loan into a LIBOR Loan or Continue a LIBOR Loan on the requested date of such Conversion or Continuation. Upon the Borrower's request, any Lender requesting compensation under this Section shall provide the Borrower with a statement setting forth the basis for requesting such compensation and the method for determining the amount thereof. Any such statement shall be conclusive absent manifest error.

-13-

Section 4.5. Treatment of Affected Loans.

If the obligation of any Lender to make LIBOR Loans or to Continue, or to Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to
Section 4.1.(b), 4.2. or 4.3., then such Lender's LIBOR Loans shall be automatically Converted into Base Rate Loans on the last day(s) of the then current Interest Period(s) for LIBOR Loans (or, in the case of a Conversion required by Section 4.1.(b) or 4.3., on such earlier date as such Lender may specify to the Borrower with a copy to the Agent) and, unless and until such Lender gives notice as provided below that the circumstances specified in
Section 4.1., 4.2. or 4.3. that gave rise to such Conversion no longer exist:
(a) to the extent that such Lender's LIBOR Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Lender's LIBOR Loans shall be applied instead to its Base Rate Loans and (b) all Loans that would otherwise be made or Continued by such Lender as LIBOR Loans shall be made or Continued instead as Base Rate Loans, and all Base Rate Loans of such Lender that would otherwise be Converted into LIBOR Loans shall remain as Base Rate Loans. If such Lender gives notice to the Borrower (with a copy to the Agent) that the circumstances specified in Section 4.1. or 4.3. that gave rise to the Conversion of such Lender's LIBOR Loans pursuant to this Section no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a time when LIBOR Loans made by other Lenders are outstanding, then such Lender's Base Rate Loans shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding LIBOR Loans, to the extent necessary so that, after giving effect thereto, all Loans held by the Lenders holding LIBOR Loans and by such Lender are held pro rata (as to principal amounts, Types and Interest Periods) in accordance with their respective Commitments.

Section 4.6. Change of Lending Office.

Each Lender agrees that it will use reasonable efforts to designate an alternate Lending Office with respect to any of its Loans affected by the matters or circumstances described in Sections 3.11., 4.1. or 4.3. to reduce the liability of the Borrower or avoid the results provided thereunder, so long as such designation is not disadvantageous to such Lender as determined by such Lender in its sole discretion, except that such Lender shall have no obligation to designate a Lending Office located in the United States of America.

ARTICLE X. THE AGENT

Section 10.1. Authorization and Action.

Each Lender hereby irrevocably appoints and authorizes the Agent to take such action as contractual representative on such Lender's behalf and to exercise such powers under this Agreement and the other Loan Documents as are specifically delegated to the Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. Nothing herein shall be construed to deem the Agent a trustee or fiduciary for any Lender nor to impose on the Agent duties or obligations other than those expressly provided for herein. Without limiting the generality of the foregoing, the use of the terms "Agent", "agent" and similar terms in the Loan Documents with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead, use of such terms is merely a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. At the request of a Lender, the Agent will forward to such Lender copies or, where appropriate, originals of the documents delivered to the Agent pursuant to this Agreement or the other Loan Documents. The Agent will also furnish to any Lender, upon the request of such Lender, a copy of any certificate or notice furnished to the Agent by the Borrower, any Loan Party or any other Affiliate of the Borrower, pursuant to this Agreement or any other Loan Document not already delivered to such Lender pursuant to the terms of this Agreement or any such other Loan Document. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of any of the Obligations), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders (or all of the Lenders if explicitly required under any other provision of this Agreement), and such instructions shall be binding upon all Lenders and all holders of any of the Obligations; provided, however, that, notwithstanding anything in this Agreement to the contrary, the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or any other Loan Document or Applicable Law. Not in limitation of the foregoing, the Agent shall not exercise any right or remedy it or the Lenders may have under any Loan Document upon the occurrence of a Default or an Event of Default unless the Requisite Lenders have so directed the Agent to exercise such right or remedy. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of the Requisite Lenders, or where applicable, all the Lenders.

-43-

Section 10.2. Agent's Reliance, Etc.

Notwithstanding any other provisions of this Agreement or any other Loan Documents, neither the Agent nor any of its directors, officers, agents, employees or counsel shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct in connection with its duties expressly set forth herein or therein. Without limiting the generality of the foregoing, the Agent: (a) may treat the payee of any Note as the holder thereof until the Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Agent; (b) may consult with legal counsel (including its own counsel or counsel for the Borrower or any Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender or any other Person and shall not be responsible to any Lender or any other Person for any statements, warranties or representations made by any Person in or in connection with this Agreement or any other Loan Document; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any of this Agreement or any other Loan Document or the satisfaction of any conditions precedent under this Agreement or any Loan Document on the part of the Borrower or other Persons or inspect the property, books or records of the Borrower or any other Person; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document, or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telephone or telecopy) believed by it to be genuine and signed, sent or given by the proper party or parties.

Section 10.3. Notice of Defaults.

The Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless the Agent has received notice from a Lender or the Borrower referring to this Agreement, describing with reasonable specificity such Default or Event of Default and stating that such notice is a "notice of default." If any Lender (excluding the Agent in its capacity as a Lender) becomes aware of any Default or Event of Default, it shall promptly send to the Agent such a "notice of default." Further, if the Agent receives such a "notice of default", the Agent shall give prompt notice thereof to the Lenders.

Section 10.4. Wells Fargo as Lender.

Wells Fargo, as a "Lender", shall have the same rights and powers under this Agreement and any other Loan Document as any other Lender and may exercise the same as though it were not the Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly indicated, include Wells Fargo in each case in its individual capacity. Wells Fargo and its affiliates may each accept deposits from, maintain deposits or credit balances for, invest in, lend money to, act as trustee under indentures of, serve as financial advisor to, and generally engage in any kind of business with the Borrower, any other Loan Party or any other affiliate thereof as if it were any other bank and without any duty to account therefor to the other Lenders. Further, the Agent and any affiliate may accept fees and other consideration from the Borrower for services in connection with this Agreement and otherwise without having to account for the same to the other Lenders. The Lenders acknowledge that, pursuant to such activities, Wells Fargo or its affiliates may receive information regarding the Parent, the Borrower, other Loan Parties, other Subsidiaries and other Affiliates (including information that may be subject to confidentiality obligations in favor of such Person) and acknowledge that the Agent shall be under no obligation to provide such information to them.

Section 10.5. Approvals of Lenders.

All communications from the Agent to any Lender requesting such Lender's determination, consent, approval or disapproval (a) shall be given in the form of a written notice to such Lender, (b) shall be accompanied by a description of the matter or issue as to which such determination, approval, consent or disapproval is requested, or shall advise such Lender where information, if any, regarding such matter or issue may be inspected, or shall otherwise describe the matter or issue to be resolved, (c) shall include, if reasonably requested by such Lender and to the extent not previously provided to such Lender, written materials and a summary of all oral information provided to the Agent by the Borrower in respect of the matter or issue to be resolved, and
(d) shall include the Agent's recommended course of action or determination in respect thereof. Each Lender shall reply promptly, but in any event within 10 Business Days of receipt of such communication (or such lesser period as may be required under the Loan Documents for the Agent to respond). Unless a Lender shall give written notice to the Agent that it specifically objects to the recommendation or determination of the Agent (together with a written explanation of the reasons behind such objection) within the applicable time period for reply, such Lender shall be deemed to have conclusively approved of or consented to such recommendation or determination.

Section 10.6. Lender Credit Decision, Etc.

Each Lender expressly acknowledges and agrees that neither the Agent nor any of its officers, directors, employees, agents, counsel, attorneys-in-fact or other affiliates has made any representations or warranties as to the financial condition, operations, creditworthiness, solvency or other information concerning the business or affairs of the Borrower, any other Loan Party, any Subsidiary or other Person to such Lender and that no act by the Agent hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any such representation or warranty by the Agent to any Lender. Each Lender acknowledges that it has, independently and without reliance upon the Agent, any other Lender or counsel to the Agent, or any of their respective officers, directors, employees and agents, and based on the financial statements of the Borrower, the Subsidiaries or any other Affiliate thereof, and inquiries of such Persons, its independent due diligence of the business and affairs of the Borrower, the Loan Parties, the Subsidiaries and other Persons, its review of the Loan Documents, the legal opinions required to be delivered to it hereunder, the advice of its own counsel and such other documents and information as it has deemed appropriate, made its own credit and legal analysis and decision to enter into this Agreement and the transaction contemplated hereby. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, any other Lender or counsel to the Agent or any of their respective officers, directors, employees and agents, and based on such review, advice, documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under the Loan Documents. The Agent shall not be required to keep itself informed as to the performance or observance by the Parent, the Borrower or any other Loan Party of the Loan Documents or any other document referred to or provided for therein or to inspect the properties or books of, or make any other investigation of, the Parent, the Borrower, any other Loan Party or any other Subsidiary. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent under this Agreement or any of the other Loan Documents, the Agent shall have no duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, financial and other condition or creditworthiness of the Borrower, any other Loan Party or any other Affiliate thereof which may come into possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or other Affiliates. Each Lender acknowledges that the Agent's legal counsel in connection with the transactions contemplated by this Agreement is only acting as counsel to the Agent and is not acting as counsel to such Lender.

Section 10.7. Indemnification of Agent.

Each Lender agrees to indemnify the Agent (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so) pro rata in accordance with such Lender's respective Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against the Agent (in its capacity as Agent but not as a "Lender") in any way relating to or arising out of the Loan Documents, any transaction contemplated hereby or thereby or any action taken or omitted by the Agent under the Loan Documents (collectively, "Indemnifiable Amounts"); provided, however, that no Lender shall be liable for any portion of such Indemnifiable Amounts to the extent resulting from the Agent's gross negligence or willful misconduct or if the Agent fails to follow the written direction of the Requisite Lenders unless such failure is pursuant to the advice of counsel of which the Lenders have received notice. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees of the counsel(s) of the Agent's own choosing) incurred by the Agent in connection with the preparation, execution, administration, or enforcement of, or legal advice with respect to the rights or responsibilities of the parties under, the Loan Documents, any suit or action brought by the Agent to enforce the terms of the Loan Documents and/or collect any Obligations, any "lender liability" suit or claim brought against the Agent and/or the Lenders, and any claim or suit brought against the Agent and/or the Lenders arising under any Environmental Laws, to the extent that the Agent is not reimbursed for such expenses by the Borrower. Such out-of-pocket expenses (including counsel fees) shall be advanced by the Lenders on the request of the Agent notwithstanding any claim or assertion that the Agent is not entitled to indemnification hereunder upon receipt of an undertaking by the Agent that the Agent will reimburse the Lenders if it is actually and finally determined by a court of competent jurisdiction that the Agent is not so entitled to indemnification. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder or under the other Loan Documents and the termination of this Agreement.

-46-

Section 10.8. Collateral Matters.

Each Lender authorizes and directs the Agent to enter into the Loan Documents for the benefit of the Lenders. Each Lender hereby agrees that, except as otherwise set forth herein, any action taken by the Requisite Lenders in accordance with the provisions of this Agreement or the Loan Documents, and the exercise by the Requisite Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders.

Section 10.9. Successor Agent.

The Agent may resign at any time as Agent under the Loan Documents by giving written notice thereof to the Lenders and the Borrower. In the event of a material breach of its duties hereunder, the Agent may be removed as Agent under the Loan Documents at any time by all Lenders (other than the Agent as a "Lender") and the Borrower upon 30-day's prior notice. Upon any such resignation or removal, the Requisite Lenders (other than, in the case of the removal of the Agent under the immediately preceding sentence, the Agent as a "Lender") shall have the right to appoint a successor Agent which appointment shall, provided no Default or Event of Default shall have occurred and be continuing, be subject to the Borrower's approval, which approval shall not be unreasonably withheld or delayed. If no successor Agent shall have been so appointed in accordance with the immediately preceding sentence, and shall have accepted such appointment, within 30 days after the resigning Agent's giving of notice of resignation or the Lenders' removal of the resigning Agent, then the resigning or removed Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender, if any Lender shall be willing to serve, and otherwise shall be an Eligible Assignee. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents. After any resigning Agent's resignation or removal hereunder as Agent, the provisions of this Article X. shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents. Notwithstanding anything contained herein to the contrary, the Agent may assign its rights and duties under the Loan Documents to any of its affiliates by giving the Borrower and each Lender prior written notice.

Section 11.3. Setoff.

Subject to Section 3.3. and in addition to any rights now or hereafter granted under Applicable Law and not by way of limitation of any such rights, the Agent, each Lender and each Participant is hereby authorized by the Borrower, at any time or from time to time, during the continuance of an Event of Default without prior notice to the Borrower or to any other Person, any such notice being hereby expressly waived, but in the case of a Lender or Participant subject to receipt of the prior written consent of the Agent exercised in its sole discretion, to set-off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, such Lender or any affiliate of the Agent or such Lender, to or for the credit or the account of the Borrower against and on account of any of the Obligations, irrespective of whether or not any or all of the Loans and all other Obligations have been declared to be, or have otherwise become, due and payable as permitted by
Section 9.2., and although such obligations shall be contingent or unmatured. Promptly following any such set-off the Agent shall notify the Borrower thereof and of the application of such set-off, provided that the failure to give such notice shall not invalidate such set-off.

Section 11.4. Litigation; Jurisdiction; Other Matters; Waivers.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT AND THE BORROWER HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE.

(b) EACH OF THE BORROWER, THE AGENT AND EACH LENDER HEREBY AGREES THAT THE FEDERAL DISTRICT COURT OF THE EASTERN DISTRICT OF PENNSYLVANIA OR, AT THE OPTION OF THE AGENT, ANY STATE COURT LOCATED IN PHILADELPHIA COUNTY, PENNSYLVANIA, SHALL HAVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG THE BORROWER, THE AGENT OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT AND THE LOANS, OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR THEREFROM. THE BORROWER AND EACH OF THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS.

-50-

(c) EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME.

(d) THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

(e) THE FOREGOING WAIVERS HAVE BEEN MADE WITH THE ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE PAYMENT OF THE LOANS AND ALL OTHER OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

Section 11.5. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, except that the Borrower may not assign or otherwise transfer any of its rights under, and no Person may assume any of the Borrower's obligations under, this Agreement or any of the other Loan Documents without the prior written consent of all of the Lenders.

(b) Any Lender may make, carry or transfer Loans at, to or for the account of, any of its branch offices or the office of an affiliate of such Lender except to the extent such transfer would result in increased costs to, or taxes payable by or for the account of, the Borrower.

(c) Any Lender may at any time grant to one or more banks or other financial institutions (each a "Participant") participating interests in its Commitments or the Obligations owing to such Lender; provided, however, any such participating interest must be for a constant percentage of a Lender's Commitments and not a varying percentage interest. Except as otherwise provided in Section 11.3., no Participant shall have any rights or benefits under this Agreement or any other Loan Document. In the event of any such grant by a Lender of a participating interest to a Participant, such Lender shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, however, such Lender may agree with the Participant that it will not, without the consent of the Participant, agree to any such amendment, modification or waiver if it requires the consent of all of the Lenders under Sections 11.6.(a), (b) or (d). An assignment or other transfer which is not permitted by subsection (d) or (e) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (c). The selling Lender shall promptly notify the Agent and the Borrower of the sale of any participation hereunder and the terms thereof.

-51-

(d) Any Lender may with the prior written consent of the Agent and the Borrower (provided, that the Borrower's consent shall not be required if a Default or Event of Default shall have occurred and be continuing) which consent, in each case, shall not be unreasonably withheld, assign to one or more Eligible Assignees (each an "Assignee") all or a portion of such Lender's Commitments and its other rights and obligations under this Agreement and such Lender's Notes; provided, however, (i) no such consent by the Borrower or Agent shall be required in the case of any assignment to another Lender or to any affiliate of a Lender; (ii) any partial assignment shall be in an amount at least equal to $10,000,000 and integral multiples of $1,000,000 in excess thereof, and after giving effect to such assignment the assigning Lender retains a Commitment, or if the Commitments have been terminated, holds Notes having an aggregate outstanding principal balance, of at least $10,000,000; (iii) after giving effect to any such assignment by the Lender then acting as Agent, such Lender shall retain a Commitment, or if the Commitments have been terminated, hold Notes having an aggregate outstanding principal balance, greater than or equal to the Commitment of each other Lender (other than any Lender whose Commitment has increased as a result of a merger or combination with another Lender); (iv) any such assignment must be of proportionate amounts of both Commitments of such Lender; (v) such Lender must give the Agent at least 10 days prior written notice of any such assignment; and (vi) each such assignment shall be effected by means of an Assignment and Acceptance Agreement. Upon execution and delivery of such instrument and payment by such Assignee to such transferor Lender of an amount equal to the purchase price agreed between such transferor Lender and such Assignee, such Assignee shall be deemed to be a Lender party to this Agreement as of the effective date of the Assignment and Acceptance Agreement and shall have all the rights and obligations of a Lender with the Commitments as set forth in such Assignment and Acceptance Agreement, and the transferor Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection
(d), the transferor Lender, the Agent and the Borrower shall make appropriate arrangements so that new Notes are issued to the Assignee and such transferor Lender, as appropriate. In connection with any such assignment, the transferor Lender shall pay to the Agent an administrative fee for processing such assignment in the amount of $3,000.

(e) The Agent shall maintain a copy of each Assignment and Acceptance Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of each Lender from time to time (the "Register"). The Agent shall give each Lender and the Borrower notice of the assignment by any Lender of its rights as contemplated by this Section. The Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement and the other Loan Documents. The Register and copies of each Assignment and Acceptance Agreement shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice to the Agent. Upon its receipt of an Assignment and Acceptance Agreement executed by an assigning Lender, together with each Note subject to such assignment (a "Surrendered Note"), the Agent shall, if such Assignment and Acceptance Agreement has been completed and if the Agent receives the processing and recording fee described in subsection (d) above, (i) accept such Assignment and Acceptance Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof, and return each Surrendered Note, to the Borrower.

-52-

(f) Notwithstanding anything in this Agreement to the contrary, and without the need to comply with any of the formal or procedural requirements of this Agreement, including this Section 11.5., any Lender may at any time and from time to time pledge and assign all or any portion of its rights under all or any of the Loan Documents to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from its obligations thereunder. To facilitate any such pledge or assignment, Agent shall, at the request of and at the expense of such Lender, enter into a letter agreement with the Federal Reserve Bank in, or substantially in, the form of the exhibit to Appendix C to the Federal Reserve Bank of New York Operating Circular No. 10.

(g) A Lender may furnish any information concerning the Borrower, any other Loan Party or any of their respective Subsidiaries in the possession of such Lender from time to time to Assignees and Participants (including prospective Assignees and Participants) subject to compliance with Section 11.8.

(h) Anything in this Section to the contrary notwithstanding, no Lender may assign or participate any interest in any Loan held by it hereunder to the Borrower, any other Loan Party or any of their respective Affiliates or Subsidiaries.

(i) Each Lender agrees that, without the prior written consent of the Borrower and the Agent, it will not make any assignment hereunder in any manner or under any circumstances that would require registration or qualification of, or filings in respect of, any Loan or Note under the Securities Act or any other securities laws of the United States of America or of any other jurisdiction.

Section 11.6. Amendments.

Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement or in any Loan Document to be given by the Lenders may be given, and any term of this Agreement or of any other Loan Document (other than any fee letter solely between the Borrower and the Agent) may be amended, and the performance or observance by the Borrower, any other Loan Party or any other Subsidiary of any terms of this Agreement or such other Loan Document (other than any fee letter solely between the Borrower and the Agent) or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Requisite Lenders (and, in the case of an amendment to any Loan Document, the written consent of each Loan Party which is party thereto). Notwithstanding the foregoing, no amendment, waiver or consent shall, unless in writing, and signed by all of the Lenders (or the Agent at the written direction of the Lenders), do any of the following:

-53-

(a) increase the Commitments of the Lenders or subject the Lenders to any additional obligations;

(b) reduce the principal of, or interest rates that have accrued or that will be charged on the outstanding principal amount of, any Loans or other Obligations;

(c) reduce the amount of any Fees payable to the Lenders hereunder;

(d) postpone any date fixed for any payment of any principal of, interest on, or Fees with respect to, any Loans or any other Obligations;

(e) change the Commitment Percentages (excluding any change as a result of an assignment of Commitments permitted under Section 11.5.(d));

(f) modify the definition of the term "Revolving Credit Termination Date," "Term Loan Facility Expiration Date" or "Term Loan Maturity Date";

(g) amend this Section or amend the definitions of the terms used in this Agreement or the other Loan Documents insofar as such definitions affect the substance of this Section;

(h) modify the definition of the term "Requisite Lenders" or modify in any other manner the number or percentage of the Lenders required to make any determinations or waive any rights hereunder or to modify any provision hereof;

(i) release any Guarantor from its obligations under the Guaranty (except for releases permitted under Section 7.14.(c));

(j) modify the terms of, or waive the Parent's compliance with, Section 8.1.(b); and

(k) waive a Default or Event of Default under subsection (a) of
Section 9.1.

No amendment, waiver or consent unless in writing and signed by the Agent, in addition to the Lenders required hereinabove to take such action, shall affect the rights or duties of the Agent under this Agreement or any of the other Loan Documents. No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon and any amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose set forth therein. No course of dealing or delay or omission on the part of the Agent or any Lender in exercising any right shall operate as a waiver thereof or otherwise be prejudicial thereto. Except as otherwise explicitly provided for herein or in any other Loan Document, no notice to or demand upon the Borrower shall entitle the Borrower to other or further notice or demand in similar or other circumstances.

-54-

Section 11.7. Nonliability of Agent and Lenders.

The relationship between the Borrower, on the one hand, and the Lenders and the Agent, on the other hand, shall be solely that of borrower and lender. Neither the Agent nor any Lender shall have any fiduciary responsibilities to the Borrower and no provision in this Agreement or in any of the other Loan Documents, and no course of dealing between or among any of the parties hereto, shall be deemed to create any fiduciary duty owing by the Agent or any Lender to any Lender, the Borrower, any Subsidiary or any other Loan Party. Neither the Agent nor any Lender undertakes any responsibility to the Parent or the Borrower to review or inform the Parent or the Borrower of any matter in connection with any phase of the business or operations of the Parent or the Borrower.

Section 11.8. Confidentiality.

Except as otherwise provided by Applicable Law, the Agent and each Lender shall utilize all non-public information obtained pursuant to the requirements of this Agreement which has been identified as confidential or proprietary by the Parent or the Borrower in accordance with its customary procedure for handling confidential information of this nature and in accordance with safe and sound banking practices but in any event may make disclosure: (a) to any of their respective affiliates (provided any such affiliate shall agree to keep such information confidential in accordance with the terms of this Section); (b) as reasonably required by any bona fide Assignee, Participant or other transferee in connection with the contemplated transfer of any Commitment or participations therein as permitted hereunder (provided they shall agree to keep such information confidential in accordance with the terms of this Section); (c) as required by any Governmental Authority or representative thereof or pursuant to legal process; (d) to the independent auditors and other professional advisors (provided they shall be notified of the confidential nature of the information of the Agent or any Lender and shall agree to keep such information confidential in accordance with the terms of this Section); and
(e) after the happening and during the continuance of an Event of Default, to any other Person, in connection with the exercise by the Agent or the Lenders of rights hereunder or under any of the other Loan Documents. The Agent and each Lender agrees to use any such non-public information solely in connection with the transactions contemplated by this Agreement and the other Loan Documents. Notwithstanding anything to the contrary set forth herein or in any other written or oral understanding or agreement to which the parties hereto are parties or by which they are bound, the parties hereto acknowledge and agree that (i) any obligations of confidentiality contained herein and therein do not apply and have not applied from the commencement of discussions between the parties to the tax treatment and tax structure of the transactions contemplated by the Loan Documents (and any related transactions or arrangements), and (ii) each party (and each of its employees, representatives, or other agents) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by the Loan Documents and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure, all within the meaning of Treasury Regulations Section 1.6011-4; provided, however, that each party recognizes that the privilege each has to maintain, in its sole discretion, the confidentiality of a communication relating to the transactions contemplated by the Loan Documents, including a confidential communication with its attorney or a confidential communication with a federally authorized tax practitioner under Section 7525 of the Internal Revenue Code, is not intended to be affected by the foregoing.

Each Guarantor, to the fullest extent permitted by Applicable Law, hereby waives notice of acceptance hereof or any presentment, demand, protest or notice of any kind, and any other act or thing, or omission or delay to do any other act or thing, which in any manner or to any extent might vary the risk of such Guarantor or which otherwise might operate to discharge such Guarantor from its obligations hereunder.

Section 8. Inability to Accelerate Loan. If the Agent and/or the Lenders are prevented under Applicable Law or otherwise from demanding or accelerating payment of any of the Guarantied Obligations by reason of any automatic stay or otherwise, the Agent and/or the Lenders shall be entitled to receive from each Guarantor, upon demand therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

-3-

Section 9. Reinstatement of Guarantied Obligations. If claim is ever made on the Agent or any Lender for repayment or recovery of any amount or amounts received in payment or on account of any of the Guarantied Obligations, and the Agent or such Lender repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body of competent jurisdiction, or (b) any settlement or compromise of any such claim effected by the Agent or such Lender with any such claimant (including the Borrower or a trustee in bankruptcy for the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Credit Agreement, any of the other Loan Documents, or any other instrument evidencing any liability of the Borrower, and such Guarantor shall be and remain liable to the Agent or such Lender for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Agent or such Lender.

Section 10. Subrogation. Each Guarantor hereby forever waives to the fullest extent possible any and all claims such Guarantor may have against the Borrower arising out of any payment by such Guarantor to the Agent and Lenders of any of the obligations pursuant to this Guaranty, including, but not limited to, all such claims of such Guarantor arising out of any right of subrogation, indemnity, reimbursement, contribution, exoneration, payment or any other claim, cause of action, right or remedy against the Borrower, whether such claim arises at law, in equity, or out of any written or oral agreement between or among such Guarantor, the Borrower or otherwise. The waivers set forth above are intended by each Guarantor, the Agent and the Lenders to be for the benefit of the Borrower, and such waivers shall be enforceable by the Borrower, or any of their successors or assigns, as an absolute defense to any action by such Guarantor against the Borrower or the assets of the Borrower, which action arises out of any payment by the Borrower to the Agent or Lenders upon any of these obligations. The waivers set forth herein may not be revoked by any Guarantor without the prior written consent of the Agent and the Borrower.

Section 11. Payments Free and Clear. Except as otherwise permitted under Section 3.11. of the Credit Agreement, all sums payable by each Guarantor hereunder, whether of principal, interest, fees, expenses, premiums or otherwise, shall be paid in full, without set-off or counterclaim or any deduction or withholding whatsoever (including any Taxes), and if such Guarantor is required by Applicable Law or by any Governmental Authority to make any such deduction or withholding, such Guarantor shall pay to the Agent and the Lenders such additional amount as will result in the receipt by the Agent and the Lenders of the full amount payable hereunder had such deduction or withholding not occurred or been required.

Section 12. Set-off. In addition to any rights now or hereafter granted under any of the other Loan Documents or Applicable Law and not by way of limitation of any such rights, each Guarantor hereby authorizes the Agent, at any time or from time to time, during the continuance of any Event of Default without any prior notice to such Guarantor or to any other Person, any such notice being hereby expressly waived, to set-off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, or any affiliate of the Agent, to or for the credit or the account of such Guarantor against and on account of any of the Guarantied Obligations, although such obligations shall be contingent or unmatured. Each Guarantor agrees, to the fullest extent permitted by Applicable Law, that any Participant may exercise rights of setoff or counterclaim and other rights with respect to its participation as fully as if such Participant were a direct creditor of such Guarantor in the amount of such participation.

-4-

Section 13. Subordination. Each Guarantor hereby expressly covenants and agrees for the benefit of the Agent and the Lenders that all obligations and liabilities of the Borrower to such Guarantor of whatever description, including without limitation, all intercompany receivables of such Guarantor from the Borrower (collectively, the "Junior Claims") shall be subordinate and junior in right of payment to all Guarantied Obligations. If an Event of Default shall have occurred and be continuing, then no Guarantor shall accept any direct or indirect payment (in cash, property, securities by setoff or otherwise) from the Borrower on account of or in any manner in respect of any Junior Claim until all of the Guarantied Obligations have been indefeasibly paid in full.

Section 14. Avoidance Provisions. It is the intent of each Guarantor, the Agent and the Lenders that in any Proceeding, such Guarantor's maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not otherwise cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) to be avoidable or unenforceable against such Guarantor in such Proceeding as a result of Applicable Law, including without limitation, (a) Section 548 of the Bankruptcy Code of 1978, as amended (the "Bankruptcy Code") and (b) any state fraudulent transfer or fraudulent conveyance act or statute applied in such Proceeding, whether by virtue of Section 544 of the Bankruptcy Code or otherwise. The Applicable Laws under which the possible avoidance or unenforceability of the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) shall be determined in any such Proceeding are referred to as the "Avoidance Provisions". Accordingly, to the extent that the obligations of any Guarantor hereunder would otherwise be subject to avoidance under the Avoidance Provisions, the maximum Guarantied Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the Guarantied Obligations are deemed to have been incurred under the Avoidance Provisions, would not cause the obligations of any Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent that would not cause the obligations of any Guarantor hereunder to be subject to avoidance under the Avoidance Provisions, and no Guarantor or any other Person shall have any right or claim under this Section as against the Agent and the Lenders that would not otherwise be available to such Person under the Avoidance Provisions.

Section 15. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the financial condition of the Loan Parties, and of all other circumstances bearing upon the risk of nonpayment of any of the Guarantied Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Agent or any Lender shall have any duty whatsoever to advise any Guarantor of information regarding such circumstances or risks.

Section 16. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH COMMONWEALTH.

SECTION 17. LITIGATION; JURISDICTION; OTHER MATTERS; WAIVERS.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT AND EACH GUARANTOR HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR IN CONNECTION WITH ANY COLLATERAL OR ANY LIEN OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE.

-5-

(b) EACH GUARANTOR, THE AGENT, AND EACH LENDER HEREBY AGREES THAT THE FEDERAL DISTRICT COURT OF THE EASTERN DISTRICT OF PENNSYLVANIA OR, AT THE OPTION OF THE AGENT, ANY STATE COURT LOCATED IN PHILADELPHIA COUNTY, PENNSYLVANIA, SHALL HAVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG ANY GUARANTOR, THE AGENT, OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY TO THIS GUARANTY, OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR THEREFROM OR THE COLLATERAL. EACH GUARANTOR AND EACH OF THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS.

(c) EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME.

(d) THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

(e) THE FOREGOING WAIVERS HAVE BEEN MADE WITH THE ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE PAYMENT OF THE LOANS AND ALL OTHER OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

Section 18. Loan Accounts. The Agent and each Lender may maintain books and accounts setting forth the amounts of principal, interest and other sums paid and payable with respect to the Guarantied Obligations, and in the case of any dispute relating to any of the Guarantied Obligations or otherwise, the entries in such books and accounts shall constitute prima facie evidence of the outstanding amount of such Guarantied Obligations and the amounts paid and payable with respect thereto absent manifest error. The failure of the Agent or any Lender to maintain such books and accounts shall not in any way relieve or discharge any Guarantor of any of its obligations hereunder.

Section 19. Waiver of Remedies. No delay or failure on the part of the Agent or any Lender in the exercise of any right or remedy it may have against any Guarantor hereunder or otherwise shall operate as a waiver thereof, and no single or partial exercise by the Agent or any Lender of any such right or remedy shall preclude other or further exercise thereof or the exercise of any other such right or remedy.

Section 20. Termination. This Guaranty shall remain in full force and effect until the indefeasible payment in full of the Obligations and the termination or cancellation of the Credit Agreement.

-6-

Section 21. Successors and Assigns. Each reference herein to the Agent or the Lenders shall be deemed to include such Person's respective successors and assigns (including, but not limited to, any holder of the Guarantied Obligations) in whose favor the provisions of this Guaranty also shall inure, and each reference herein to each Guarantor shall be deemed to include such Guarantor's successors and assigns, upon whom this Guaranty also shall be binding. The Lenders may, in accordance with the applicable provisions of the Credit Agreement, assign, transfer or sell any Guarantied Obligations, or grant or sell participation in any Guarantied Obligations, to any Person without the consent of, or notice to, any Guarantor and without releasing, discharging or modifying any Guarantor's obligations hereunder. Each Guarantor hereby consents to the delivery by the Agent or any Lender to any Assignee or Participant (or any prospective Assignee or Participant) of any financial or other information regarding any Loan Party. No Guarantor may assign or transfer its obligations hereunder to any Person.

Section 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE GUARANTORS HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH GUARANTOR CONFIRMS THAT IT IS LIABLE FOR THE FULL AMOUNT OF THE "GUARANTIED OBLIGATIONS" AND ALL OF THE OBLIGATIONS AND LIABILITIES OF EACH OF THE OTHER GUARANTORS HEREUNDER.

Section 23. Amendments. This Guaranty may not be amended except in writing signed by the Agent and each Guarantor.

Section 24. Payments. All payments to be made by any Guarantor pursuant to this Guaranty shall be made in Dollars, in immediately available funds to the Agent at its Lending Office, not later than 11:00 a.m., on the date one Business Day after demand therefor.

Section 25. Notices. All notices, requests and other communications hereunder shall be in writing (including facsimile transmission or similar writing) and shall be given (a) to each Guarantor at its address set forth below its signature hereto, (b) to the Agent or any Lender at its address for notices provided for in the Credit Agreement, or (c) as to each such party at such other address as such party shall designate in a written notice to the other parties. Each such notice, request or other communication shall be effective (i) if mailed, when received; (ii) if telecopied, when transmitted; or (iii) if hand delivered, when delivered; provided, however, that any notice of a change of address for notices shall not be effective until received.

Section 26. Severability. In case any provision of this Guaranty shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

WHEREAS, the Borrower, the Parent, the Lenders party hereto and the Agent desire to amend certain provisions of the Credit Agreement on the terms and conditions contained herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the parties hereto, the parties hereto hereby agree as follows:

Section 1. Specific Amendments to Credit Agreement. The parties hereto agree that the Credit Agreement is amended as follows:

(a) The Credit Agreement is amended by adding to Annex I to the Credit Agreement the following definitions in their appropriate alphabetical location:

(b) The Credit Agreement is amended by deleting the table appearing in the definition of the term "Applicable Margin" set forth in Annex I to the Credit Agreement and substituting in its place the following:

--------------------------------------------------------------------------------
                  Ratio of Total Liabilities to
   Level               Gross Asset Value                 Applicable Margin
--------------------------------------------------------------------------------
     1      Less than or equal to 0.40 to 1.00                  1.30%
--------------------------------------------------------------------------------
     2      Greater than 0.40 to 1.00 but less than             1.50%
               or equal to 0.50 to 1.00
--------------------------------------------------------------------------------
     3      Greater than 0.50 to 1.00 but less than             1.65%

(c) The Credit Agreement is amended by adding to the end of definition of the term "Applicable Margin" set forth in Annex I to the Credit Agreement the following sentence:

In addition to the foregoing, the Applicable Margin for Revolving Loans and Term Loans shall be determined by the Agent based on the ratio of Total Liabilities to Gross Asset Value immediately after the following (and after giving effect thereto including the incurrence or repayment of any Indebtedness in connection therewith): (x) the acquisition of each Rouse Property and (y) the disposition of each Property in the Multi-Family Disposition, in each case as such ratio is set forth in a Pricing Certificate which the Borrower shall deliver to the Agent within 1 Business Day of the occurrence of any such event.

(d) The Credit Agreement is amended by adding the following to the end of the definition of the term "Total Liabilities" set forth in Annex I to the Credit Agreement:

For purposes of determining the Total Liabilities of the Parent and the Subsidiaries, the amount of any Indebtedness assumed by the Parent or any Subsidiary at the time of an acquisition which the Parent is required under GAAP to reflect at fair value on a balance sheet, shall be equal to outstanding principal balance of such Indebtedness and not the fair value of such Indebtedness as would be reflected on the Parent's balance sheet.

(e) The Credit Agreement is amended by deleting subsections (b) and (i) of Section 10.1. in their entirety and substituting in their respective places the following:

(b) Ratio of Total Liabilities to Gross Asset Value.

(i) Floating Rate Indebtedness. The Parent and the Borrower will not, and will not permit any of their respective Subsidiaries to, incur, assume or suffer to exist at any time Floating Rate Indebtedness in an aggregate outstanding principal amount in excess of $400,000,000.

Section 2. Conditions Precedent. The effectiveness of this Amendment is subject to receipt by the Agent of each of the following, each in form and substance satisfactory to the Agent:

Section 3. Representations. The Parent and the Borrower each represents and warrants to the Agent and the Lenders that:

(a) Authorization. The Parent and the Borrower each has the right and power, and has taken all necessary action to authorize it, to execute and deliver this Amendment and to perform its obligations hereunder and under the Credit Agreement, as amended by this Amendment, in accordance with their respective terms. This Amendment has been duly executed and delivered by the duly authorized officers of the Parent (on behalf of itself and as general partner of the Borrower) and each of this Amendment, and the Credit Agreement as amended by this Amendment, is a legal, valid and binding obligation of each of the Parent and the Borrower enforceable against each such Person in accordance with its respective terms, except as the same may be limited by bankruptcy, insolvency, fraudulent conveyance and other similar laws affecting the rights of creditors generally and the availability of equitable remedies for the enforcement of certain obligations (other than the payment of principal) contained herein or therein may be limited by equitable principles generally.

(b) Compliance with Laws, etc. The execution and delivery of this Amendment, and the performance of this Amendment, and the Credit Agreement as amended by this Amendment, in accordance with their respective terms, do not and will not, by the passage of time, the giving of notice, or both: (i) require any Governmental Approval or violate any Applicable Law (including all Environmental Laws) relating to any Loan Party or any other Subsidiary; (ii) result in a breach of or constitute a default under the declaration of trust, certificate or articles of incorporation, bylaws, partnership agreement or other organizational documents of any Loan Party or any other Subsidiary, or any indenture, agreement or other instrument to which any Loan Party or any other Subsidiary is a party or by which it or any of its respective properties may be bound; or (iii) result in or require the creation or imposition of any Lien upon or with respect to any property now owned or hereafter acquired by any Loan Party or any other Subsidiary other than in favor of the Agent for the benefit of the Lenders.


(c) No Default. No Default or Event of Default has occurred and is continuing as of the date hereof nor will exist immediately after giving effect to this Amendment.

Section 4. Reaffirmation of Representations. The Parent and the Borrower each hereby repeats and reaffirms all representations and warranties made by such Person to the Agent and the Lenders in the Credit Agreement and the other Loan Documents to which it is a party on and as of the date hereof except to the extent that such representations and warranties expressly relate solely to an earlier date (in which case such representations and warranties were true and accurate on and as of such earlier date) and except for changes in factual circumstances not prohibited under the Loan Documents.
