Item 5. Other Events

On June 21, 2004, Chelsea Property Group, Inc. ("Chelsea") and Simon Property Group, Inc. ("Simon") announced that they had entered into a definitive Agreement and Plan of Merger (the "Merger Agreement"), dated as of June 20, 2004, by and among Simon, Simon Property Group, L.P. ("SPG LP"), Simon Acquisition I, LLC ("Merger Sub"), Simon Acquisition II, LLC ("L.P. Merger Sub"), Chelsea and CPG Partners, L.P. ("CPG LP"), which provides for, among other things, the acquisition of Chelsea by Simon.

Pursuant to the Merger Agreement, Merger Sub shall merge with and into Chelsea, with Chelsea as the surviving corporation (the "REIT Merger"). As a result of the REIT Merger, each share (other than shares owned by Simon, Chelsea or their respective wholly owned subsidiaries) of common stock, par value par value $.01 per share, of Chelsea ("Chelsea Common Stock") shall be converted into the right to receive (i) $36.00 in cash (the "Base Cash Consideration" which may be adjusted pursuant to the proviso of the next sentence), (ii) a fraction of a fully paid and nonassessable share of common stock, par value $0.0001 per share, of Simon ("Simon Common Stock") equal to the Common Exchange Ratio (as defined below and which Common Exchange Ratio is subject to adjustment as set forth below), and (iii) a fraction of a fully paid and nonassessable share of 6% preferred stock of Simon (the "Simon 6% Preferred Stock") equal to the Preferred Exchange Ratio (as defined below). The shares of Simon 6% Preferred Stock have a liquidation preference of $50 per share, have no maturity date, are convertible at the option of the holder into Simon Common Stock upon, among other things, the achievement of certain price targets for the Simon Common Stock, and are redeemable at the option of Simon after five years from the date of issuance upon the achievement of certain price targets for the Simon Common Stock.

As used herein, the "Common Exchange Ratio" means 0.2936 and the "Preferred Exchange Ratio" means 0.3000, each appropriately adjusted for any stock splits, reverse stock splits, stock dividends, recapitalizations or other similar transactions; provided, however, that (i) in the event that the average of ten randomly selected closing prices of Simon Common Stock on the New York Stock Exchange (the "NYSE") during the period of the 30 most recent trading days ending on the fifth business day prior to the Closing Date (the "Closing Date Market Price") is greater than $58.75 (the "Upper Limit Price"), then the Common Exchange Ratio shall be adjusted to equal 0.2936 multiplied by a fraction, the numerator of which is the Upper Limit Price, and the denominator of which is the Closing Date Market Price, and (ii) in the event that the Closing Date Market Price is less than $43.43 (the "Lower Limit Price"), then the Base Cash Consideration shall be increased by an amount equal to the product of (x) an amount equal to (1) 0.2936 multiplied by a fraction, the numerator of which is the Lower Limit Price, and the denominator of which is the Closing Date Market Price less (2) the Common Exchange Ratio multiplied by (y) the Closing Date Market Price, rounded to the nearest cent. In addition, in connection with the REIT Merger, each share (other than shares owned by Simon, Chelsea or their respective wholly owned subsidiaries) of 8³/8% Series A Cumulative Redeemable Preferred Stock of Chelsea issued and outstanding immediately prior to the effective time of the REIT Merger shall be converted into the right to receive one fully paid and nonassessable share of Simon 8³/8% cumulative redeemable preferred stock.

Pursuant to the Merger Agreement, L.P. Merger Sub shall merge with and into CPG LP, with CPG LP as the surviving partnership (the "OP Merger"). As a result of the OP Merger, each common unit (other than units owned by Simon, Chelsea or their respective wholly owned subsidiaries) of CPG LP ("CPG LP Common Units") shall be converted into the right to receive (i) a fraction of a SPG LP common interest ("SPG LP Common Interest") equal to the Common Interest Exchange Ratio (as defined below) and (ii) a fraction of a SPG LP preferred interest ("SPG LP Preferred Interest" and, together with the SPG LP Common Interests", the "SPG LP Interests") equal to the Preferred Interest Exchange Ratio (as defined below) (collectively, the "OP Merger Consideration"). The SPG LP Preferred Interests shall have substantially the same economic terms as the Simon 6% Preferred Stock,

except that they shall be (i) convertible at the option of the holder into SPG LP Common Units on substantially the same terms as the Simon 6% Preferred Stock shall be convertible into Simon Common Stock and (ii) exchangeable at the option of the holder for Simon 6% Preferred Stock.

As used herein, the "Common Interest Exchange Ratio" means 0.6459 and the "Preferred Interest Exchange Ratio" means 0.6600, each appropriately adjusted for any stock splits, reverse stock splits, stock dividends, recapitalizations or other similar transactions; provided, however, that (i) in the event that the Closing Date Market Price is greater than the Upper Limit Price, then the Common Interest Exchange Ratio shall be adjusted to equal 0.6459 multiplied by a fraction, the numerator of which is the Upper Limit Price, and the denominator of which is the Closing Date Market Price, and (ii) in the event that the Closing Date Market Price is less than the Lower Limit Price, then the Common Interest Exchange Ratio shall be adjusted to equal 0.6459 multiplied by a fraction, the numerator of which is the Lower Limit Price, and the denominator of which is the Closing Date Market Price.

Holders of CPG LP Common Units shall have the option to elect to exchange with SPG LP their CPG LP Common Units for the OP Merger Consideration immediately prior to the effective time of the OP Merger. If all of the holders of CPG LP Common Units elect to exchange their units for the OP Merger Consideration, Simon does not currently contemplate consummating the OP Merger.

In connection with the Merger Agreement, Simon and SPG LP entered into voting agreements, each dated as of June 20, 2004 (the "Voting Agreements"), with certain limited partners of CPG LP (the "CPG Limited Partners") who hold approximately 78.5% of the CPG LP Common Units and approximately 0.7% of the outstanding Chelsea Common Stock. Pursuant to the Voting Agreements, the CPG Limited Partners agreed to vote their CPG LP Common Units and their Chelsea Common Stock in favor of the OP Merger and the REIT Merger, respectively.

Consummation of the REIT Merger is subject to various conditions, including: (i) receipt of the approval of at least 66²/3% of the voting power of the outstanding shares of Chelsea Common Stock entitled to vote on the REIT Merger; (ii) receipt of the affirmative vote or consent of the holders of a majority of the voting power of CPG LP's limited partnership units entitled to vote on the OP Merger; (iii) the declaration of effectiveness by the Securities and Exchange Commission of a registration statement covering the Simon Common Stock and Simon 6% Preferred Stock to be issued in the REIT Merger; (iv) listing on the NYSE, subject to notice of issuance, of the shares of Simon Common Stock and Simon 6% Preferred Stock to be issued in the REIT Merger and the shares of Simon Common Stock to be reserved for issuance upon conversion of SPG LP Interests issued in the OP Merger; and (v) receipt of tax opinions.

A copy of the press release issued by Simon and Chelsea on June 21, 2004, the Merger Agreement, the Voting Agreements and the Simon 6% Preferred Stock Term Sheet are attached hereto as Exhibits 99.1, 99.2, 99.3 and 99.4, respectively, and are each incorporated herein by this reference.

FOR IMMEDIATE RELEASE

SIMON PROPERTY GROUP TO ACQUIRE CHELSEA PROPERTY GROUP

Indianapolis, IN—June 21, 2004—Simon Property Group, Inc. (NYSE: SPG) ("Simon") and Chelsea Property Group, Inc. (NYSE: CPG) ("Chelsea") announced today that they have signed a definitive merger agreement whereby Simon will acquire all of the outstanding common stock and operating partnership units of Chelsea in a transaction valued at approximately $3.5 billion. Simon will also assume Chelsea's existing indebtedness and preferred stock, which totaled approximately $1.3 billion as of March 31, 2004.

Under terms of the agreement, which has been unanimously approved by each company's Board of Directors, Simon will pay consideration of $66.00 per share for all of Chelsea's outstanding common stock and units. The consideration to Chelsea's common shareholders comprises $36.00 in cash, $15.00 of SPG common stock based on a fixed conversion ratio of 0.2936 per Chelsea common share, and $15.00 of a new issue of SPG convertible preferred stock. The new series of convertible preferred shares yield 6.0%, have a liquidation preference of $50 per share, and are convertible into SPG common stock at $63.86 per share, with a contingent conversion feature of an additional 25%. This will be a taxable transaction to Chelsea common shareholders. Chelsea unitholders will receive 100% of their consideration in equity, equally split between Simon common units and convertible preferred units. The Chelsea operating partnership, CPG Partners, L.P., will become a wholly-owned subsidiary of the Simon operating partnership, Simon Property Group, L.P.

Chelsea Property Group is the leading owner, developer and manager of Premium Outlet® centers in the U.S. and Asia. Its portfolio includes 35 premium outlet centers (31 in the U.S. and 4 in Japan) located in major metropolitan markets such as New York, Los Angeles and Boston, and tourist destinations such as Orlando, Las Vegas and Palm Springs. As of March 31, 2004, the 31 domestic centers were 98% occupied and generated sales per square foot of $404. Chelsea's four premium outlet centers in Japan, located near Tokyo, Osaka and Fukuoka, are fully leased and generated average sales of more than $800 per square foot during the twelve months ended March 31, 2004.

Commenting on the transaction, David Simon, SPG CEO, stated "Chelsea is a significant opportunity for Simon as it represents a great strategic fit and a strong driver of growth for us going forward. Chelsea and Simon have pursued identical strategies over the past decade, each leading the consolidation in our respective sectors while focusing on highly-productive, high-quality retail real estate. Chelsea is the preeminent brand in the premium outlet industry, just as Simon is in the regional mall industry, and we've had three very successful joint ventures between the two companies. We are very excited to welcome David Bloom and the Chelsea team to the Simon organization."

David Bloom, Chelsea Chairman and CEO, commented, "We are extremely pleased to join forces with Simon in a transaction that recognizes the value of Chelsea Property Group. Simon's asset base and tenant relationships are unparalleled in the retail industry, and we believe they will accelerate our already industry-leading growth rate. In addition, Simon's ancillary revenue-generating programs can be applied to our premium outlet portfolio. Lastly, our international presence in Asia and Simon's presence in Europe will result in a combined organization with a truly global platform from which to grow both the full-priced and premium outlet retail real estate businesses."

Chelsea will be managed as a division of SPG and will continue to be headquartered in Roseland, New Jersey with David Bloom and the existing Chelsea management team continuing in their current roles. David Bloom will also join the Simon Property Group Board as an Advisory Director.

Simon expects an initial year unlevered yield of 7.2% from the transaction, and expects the transaction to be at least $0.09 per share accretive to 2005 Funds from Operations ("FFO") and $0.18 accretive to 2006 FFO. The transaction is subject to approval by Chelsea's shareholders, as well as customary closing conditions, and is expected to close during the fourth quarter of 2004.

Simon expects to fund the cash portion of the transaction on an interim basis with a $1.8 billion acquisition facility. Simon was advised in this transaction by UBS Investment Bank, who rendered a fairness opinion to the Simon Board of Directors, and by Morgan Stanley. Chelsea was advised by Merrill Lynch & Co., who rendered a fairness opinion to the Chelsea Board of Directors.

Conference Call

Simon and Chelsea will conduct a conference call to discuss the transaction today at 11:00 a.m. Eastern Daylight (New York) time. If you would like to participate in the teleconference, please dial 888-482-0024 (domestic) or 617-801-9702 (international) and enter the passcode "21858186." If you are unable to participate in the call, a "playback" will be available until July 2, 2004 at 5:00 p.m. Eastern Daylight time by dialing 888-286-8010 (domestic) or 617-801-6888 (international) and entering the passcode "27444414." An online simulcast of the call and an investor presentation for the transaction will be available on the "Presentations and Other Company Reports" page of the Investor Relations section of the Simon website at www.simon.com. An online replay of the call will be available until July 2, 2004 at www.simon.com.

Forward-Looking Statements

Estimates of future Funds from Operations ("FFO") and other statements regarding future operations are forward-looking statements within the meaning of the federal securities laws. Although Simon believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that its expectations will be attained, and it is possible that our actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Simon undertakes no obligation to publicly update or revise any forward-looking statements whether as a result of new information, future events or otherwise.

Those risks and uncertainties include, but are not limited to, the national, regional and local economic climate, competitive market forces, changes in market rental rates, trends in the retail industry, the inability to collect rent due to the bankruptcy or insolvency of tenants or otherwise, acquisitions and changes in market rates of interest or foreign currency. The reader is directed to Simon's various filings with the Securities and Exchange Commission, including quarterly reports on Form 10-Q, reports on Form 8-K and annual reports on Form 10-K for a discussion of such risks and uncertainties.

Funds from Operations

Simon considers FFO a key measure of its operating performance that is not specifically defined by accounting principles generally accepted in the United States ("GAAP"). Simon believes that FFO is helpful to investors because it is a widely recognized measure of the performance of real estate investment trusts and provides a relevant basis for comparison among REITs.

Simon Property Group, Inc., headquartered in Indianapolis, Indiana, is a real estate investment trust engaged in the ownership, development and management of income-producing properties, primarily regional malls and community shopping centers. Through its subsidiary partnerships, it

currently owns or has an interest in 247 properties in North America containing an aggregate of 192 million square feet of gross leasable area in 37 states plus Canada and Puerto Rico. Simon also holds interests in 48 assets in Europe (in France, Italy, Poland and Portugal). Additional Simon Property Group information is available at www.simon.com.

Chelsea Property Group, Inc. is a fully integrated, self-administered and self-managed real estate investment trust (REIT) with interests in 60 Premium Outlet® and other shopping centers—containing 16.6 million square feet of gross leasable area—in 31 states and Japan.

ARTICLE I.

The Mergers

SECTION 1.01. The Mergers.

(a) REIT Merger. On the terms and subject to the conditions set forth in this Agreement, at the REIT Effective Time, Merger Sub shall be merged with and into the Company. At the REIT Effective Time, the separate existence of Merger Sub shall cease and the Company shall continue as the surviving company (the "Surviving Company") and a wholly owned Subsidiary of Parent L.P. The parties hereto intend the REIT Merger to be a taxable purchase of the Company Common Stock.

(b) OP Merger. On the terms and subject to the conditions set forth in this Agreement, immediately following the REIT Merger, L.P. Merger Sub shall be merged with and into Company L.P. At such time, the separate existence of L.P. Merger Sub shall cease and Company L.P. shall continue as the surviving partnership (the "Surviving L.P.").

(a) Organizational Documents. The charter of the Company shall be amended and restated at and as of the REIT Effective Time in accordance with the instructions of Parent (and subject to the prior consent of the Company, which consent shall not be unreasonably withheld) and, as so amended, such charter shall be the charter of the Surviving Company until thereafter changed or amended as provided therein or by applicable Law. The by-laws of the Company shall be amended and restated at and as of the REIT Effective Time in accordance with the instructions of Parent (and subject to the prior consent of the Company, which consent shall not be unreasonably withheld) and, as so amended, such by-laws shall be the by-laws of the Surviving Company until thereafter changed or amended as provided therein or by applicable Law.

(b) Management. The officers of the Company as of the REIT Effective Time shall be the officers of the Surviving Company, until the earlier of their resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly elected and qualified, as the case may be. The directors of the Company immediately prior to the REIT Effective Time shall submit their resignations to be effective as of the REIT Effective Time. The individuals designated by Parent no later than three business days prior to the REIT Closing shall, as of the REIT Effective Time, be the directors of the Surviving Company until the earlier of their resignation or removal or otherwise ceasing to be a director or until their respective successors are duly elected and qualified.

SECTION 1.07. Effect of REIT Merger on Capital Stock.

(a) Each share of Company Common Stock issued and outstanding immediately prior to the REIT Effective Time (other than shares of Company Common Stock owned or held by Parent, Merger Sub, the Company or any of their respective direct or indirect wholly owned Subsidiaries, all of which shall be canceled as provided in Section 1.07(e)) shall be converted into the right to receive (i) $36.00 in cash (the "Base Cash Consideration" and, as the same may be adjusted pursuant to the proviso of the last sentence of this Section 1.07, the "Cash Consideration"), (ii) a fraction of a fully paid and

nonassessable share of Parent Common Stock equal to the Common Exchange Ratio (which Common Exchange Ratio is subject to adjustment as set forth below), subject to Section 2.05 with respect to fractional shares, and (iii) a fraction of a fully paid and nonassessable share of 6% Preferred Stock of Parent having the terms set forth in Exhibit E hereto (and to be created prior to the REIT Effective Time by the filing of a certificate of designation in form and substance (as to those terms not set forth in Exhibit E hereto) reasonably satisfactory to the Company) ("Parent 6% Preferred Stock") equal to the Preferred Exchange Ratio, subject to Section 2.05 with respect to fractional shares (collectively, the "REIT Merger Consideration"). For purposes of this Agreement, the "Common Exchange Ratio" means 0.2936 and the "Preferred Exchange Ratio" means 0.3000, each appropriately adjusted for any stock splits, reverse stock splits, stock dividends, recapitalizations or other similar transactions; provided, however, that (i) in the event that the average of ten randomly selected (in a manner reasonably acceptable to Parent and the Company) closing prices of Parent Common Stock on the NYSE during the period of the 30 most recent trading days ending on the fifth business day prior to the Closing Date (the "Closing Date Market Price") is greater than $58.75 (the "Upper Limit Price"), then the Common Exchange Ratio shall be adjusted to equal 0.2936 multiplied by a fraction, the numerator of which is the Upper Limit Price, and the denominator of which is the Closing Date Market Price, and (ii) in the event that the Closing Date Market Price is less than $43.43 (the "Lower Limit Price"), then the Base Cash Consideration shall be increased by an amount equal to the product of (x) an amount equal to (1) 0.2936 multiplied by a fraction, the numerator of which is the Lower Limit Price, and the denominator of which is the Closing Date Market Price less (2) the Common Exchange Ratio multiplied by (y) the Closing Date Market Price, rounded to the nearest cent.

(b) Each share of 8³/8% Series A Cumulative Redeemable Preferred Stock of the Company (the "Company Series A Preferred Stock") issued and outstanding immediately prior to the REIT Effective Time (other than shares of Company Series A Preferred Stock owned or held by Parent, Merger Sub, the Company or any of their respective direct or indirect wholly owned Subsidiaries, all of which shall be canceled as provided in Section 1.07(e)), shall be converted into the right to receive one fully paid and nonassessable share of Parent 8³/8% cumulative redeemable preferred stock (the "Parent 8³/8% Preferred Stock"). Immediately prior to the REIT Effective Time, the articles of incorporation of Parent shall be amended in accordance with Delaware law in order to create the Parent 8³/8% Preferred Stock, which will have the same terms and rights as the Company Series A Preferred Stock, including with respect to distribution and rights upon liquidation, dissolution or winding up, and shall be pari passu with all Parent Preferred Stock at the Closing Date as to distributions and rights upon liquidation, dissolution or winding up.

(c) Any outstanding shares of 9% Series B Cumulative Redeemable Preferred Stock of the Company ("Company Series B Preferred Stock") shall be redeemed prior to the REIT Effective Time in accordance with the Charter so that no shares of Company Series B Preferred Stock shall be outstanding at the REIT Effective Time, and any security issued in connection with the redemption of the Company Series B Preferred Stock shall be redeemed for cash prior to the REIT Effective Time.

(d) As a result of the REIT Merger and without any action on the part of the holders thereof, at the REIT Effective Time, all shares of Company Common Stock and Company Series A Preferred Stock (other than shares referred to in Sections 1.07(e)) shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a certificate which immediately prior to the REIT Effective Time represented any such shares (a "Certificate") shall thereafter cease to have any rights with respect to such shares of Company Common Stock or Company Series A Preferred Stock (as the case may be), except (i) the right to receive the REIT Merger Consideration or Parent 8³/8% Preferred Stock, as the case may be, (ii) any cash in lieu of fractional shares of Parent Common Stock and/or Parent 6% Preferred Stock to be issued or paid in consideration for shares of Company Common Stock, and (iii) any dividends or other distributions to which holders become entitled, all in accordance with Article II upon the surrender of such Certificate.

(e) Each share of Company Common Stock and Company Series A Preferred Stock issued and owned or held by Parent, Merger Sub, the Company or any of their respective direct or indirect wholly owned Subsidiaries at the REIT Effective Time shall, by virtue of the REIT Merger, cease to be outstanding and shall be canceled and retired and shall cease to exist and no REIT Merger Consideration or other consideration shall be delivered in exchange therefor.

(f) Each membership interest of Merger Sub shall be converted into one share of common stock of the Surviving Company in the REIT Merger and such shares shall constitute the only outstanding equity interests of the Surviving Company at the REIT Effective Time. All membership interests in Merger Sub so converted shall cease to be outstanding and shall be canceled and retired and shall cease to exist.

(g) If prior to the REIT Effective Time, Parent or the Company, as the case may be, should split, combine or otherwise reclassify the Parent Common Stock or the Company Common Stock, or pay a stock dividend or other stock distribution in Parent Common Stock or Company Common Stock, as applicable, or otherwise change the Parent Common Stock or Company Common Stock into any other securities, or make any other such stock dividend or distribution in capital stock of Parent or the Company in respect of the Parent Common Stock or the Company Common Stock, respectively, then any number or amount contained herein which is based upon the price of the Parent Common Stock or the number of shares of Company Common Stock or Parent Common Stock, as the case may be (including but not limited to the Cash Consideration, the Common Exchange Ratio and the Preferred Exchange Ratio), will be appropriately adjusted to reflect such split, combination, dividend or other distribution or change.

SECTION 1.08. Company Options.

(a) Except as otherwise set forth in Section 1.08(c), the Company shall take all actions necessary and appropriate to provide that at the REIT Effective Time, each outstanding and unexercised option to purchase shares of Company Common Stock granted under any of the Company Option Plans or otherwise (each, a "Company Option"), whether or not exercisable or vested, shall be converted into an option to purchase Parent Common Stock (each, a "New Parent Option"), on the same terms and conditions as were applicable under the Company Option (but taking into account any changes thereto, including the acceleration thereof, provided for in, or required or permitted by, the Company Option Plans, any award agreement or other agreement set forth on the Company Disclosure Letter or such option grant by reason of this Agreement and the transactions contemplated hereby). Each New Parent Option shall be exercisable for a number of shares of Parent Common Stock equal to (i) the number of shares of Company Common Stock subject to the Company Option to which such New Parent option relates, multiplied by (ii) the Option Exchange Ratio, rounded to the nearest share. The per share exercise price of each New Parent Option shall equal (A) the per share exercise price of the Company Option to which such New Parent Option relates, divided by (B) the Option Exchange Ratio, rounded to the nearest one-hundredth of a cent. For this purpose, the "Option Exchange Ratio" shall be equal to a fraction, the numerator of which is the per share dollar value of the REIT Merger Consideration on the Closing Date, and the denominator of which is the closing price of a share of Parent Common Stock quoted on the New York Stock Exchange (the "NYSE") on the Closing Date; provided, however, that in the case of any Company Option to which Section 421 of the Code as of the REIT Effective Time (after taking into account the effect of any accelerated vesting thereof) applies by reason of its qualification under Section 422 of the Code, the exercise price, the number of shares subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Code.

(b) Subject to Section 1.08(c) and the terms of the Company Option Plans and applicable Laws, the Company and Parent shall take all actions necessary and appropriate to cause the Company Option Plans to be assumed by Parent at the REIT Effective Time, and ensure that no holder of Company Options or other awards under such plans or programs will have any right to acquire any interest in the

Surviving Company, as a result of the exercise of Company Options or other awards or rights pursuant to such Company Option Plans. As of the REIT Effective Time, Parent shall assume the obligations of the Company under the Company Option Plans, and from and after the REIT Effective Time, except as otherwise set forth herein, the terms of each Company Option and the Company Option Plan under which such Company Option was initially granted, in each case, as in effect immediately prior to the REIT Effective Time, shall continue to apply to the corresponding New Parent Option.

(c) Prior to the REIT Effective Time and subject to the terms of the Company Option Plans, the Company shall take all actions necessary and appropriate to allow each holder of a Company Option (whether or not exercisable or vested) to elect, in lieu of the treatment provided in Section 1.08(a), to convert each Company Option so held into the right to receive an amount of cash at the REIT Effective Time equal to the product of (i) the excess, if any, of the per share dollar value of the REIT Merger Consideration on the Closing Date over the per share exercise price of such Company Option and (ii) the number of shares of Company Common Stock subject to such Company Option (such payment to be net of all applicable withholding taxes). The Company shall notify Parent not later than five days prior to the REIT Effective Time of the number of Company Options for which the treatment provided in this Section 1.08(c) has been elected and the total amount of cash payable pursuant to such elections.

(d) Prior to the REIT Effective Time, the Company shall take all necessary action for the adjustment of the Company Options under this Section 1.08. Parent shall reserve for issuance a number of shares of Parent Common Stock at least equal to the number of shares of Parent Common Stock that will be subject to the Company Options. As soon as practicable following the REIT Effective Time, Parent shall file a registration statement on Form S-8 (or any successor, or if Form S-8 is not available, other appropriate, forms) with respect to the shares of Parent Common Stock subject to the Company Options and shall maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding.

SECTION 1.09. Effect of OP Merger on Interests of Constituent Entities.

(a) As of the OP Effective Time, without any further action on the part of any holder of Company L.P. Units or any other party hereto:

(i) The Company GP Units shall be converted into a general partnership interest in the Surviving L.P. representing a percentage of the partnership interests therein equal to 99.99% less the Exchange Percentage, entitling the holder thereof to such rights, duties and obligations as are more fully set forth in the Agreement of Limited Partnership of the Surviving L.P. All Company GP Units so converted shall cease to be outstanding and shall be canceled and retired and shall cease to exist;

(ii) Each Company Common Unit (other than any Company Common Units held by Parent, Parent L.P., L.P. Merger Sub, the Company, Company L.P. or any of their respective direct or indirect wholly owned Subsidiaries which (other than as set forth in Section 1.09(a)(iv)) shall, by virtue of the OP Merger, cease to be outstanding and shall be canceled and retired and no OP Merger Consideration or other consideration shall be delivered in exchange therefor) held by the limited partners of Company L.P. immediately prior to the effectiveness of the OP Merger shall be converted into the right to receive (i) a fraction of a Parent L.P. Common Interest equal to the Common Interest Exchange Ratio and (ii) a fraction of a Parent L.P. Preferred Interest equal to the Preferred Interest Exchange Ratio (collectively, the "OP Merger Consideration"). For purposes of this Agreement, the "Common Interest Exchange Ratio" means 0.6459 and the "Preferred Interest Exchange Ratio" means 0.6600, each appropriately adjusted for any stock splits, reverse stock splits, stock dividends, recapitalizations or other similar transactions; provided, however, that (i) in the event that the Closing Date Market Price is greater than the Upper Limit Price, then the Common Interest Exchange Ratio shall be adjusted to equal 0.6459 multiplied by a fraction, the numerator

of which is the Upper Limit Price, and the denominator of which is the Closing Date Market Price, and (ii) in the event that the Closing Date Market Price is less than the Lower Limit Price, then the Common Interest Exchange Ratio shall be adjusted to equal 0.6459 multiplied by a fraction, the numerator of which is the Lower Limit Price, and the denominator of which is the Closing Date Market Price. As a result of the OP Merger and without any action on the part of the holders thereof, at the OP Effective Time, all Company Common Units shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of Company Common Units shall thereafter cease to have any rights with respect to such Company Common Units, except the right to receive the OP Merger Consideration and any dividends or other distributions to which such holder becomes entitled in accordance with Article II upon the exchange of such Company Common Unit;

(iii) The limited liability company interests in L.P. Merger Sub outstanding immediately prior to the effectiveness of the OP Merger shall be converted into a limited partnership interest in the Surviving L.P. representing 0.01% of the partnership interests therein, entitling Simon Acquisition Holdings II, LLC to such rights, duties and obligations as are more fully set forth in the Agreement of Limited Partnership of the Surviving L.P. All limited liability company interests in L.P. Merger Sub so converted shall cease to be outstanding and shall be canceled and retired and shall cease to exist; and

(iv) Each Company Common Unit held by Parent L.P. at the OP Effective Time as a result of any Company Common Unit Exchange shall be converted into a limited partnership interest in the Surviving L.P. in a percentage equal to the Exchange Percentage, entitling Parent L.P. to such rights, duties and obligations as are more fully set forth in the Agreement of Limited Partnership of the Surviving L.P. All Company Common Units so converted shall cease to be outstanding and shall be canceled and retired and shall cease to exist.

(b) Each Company L.P. Series A Preferred Unit issued and outstanding shall, by virtue of the OP Merger, cease to be outstanding and shall be canceled and retired and no OP Merger Consideration or other consideration shall be delivered in exchange therefor.

(c) Any outstanding shares of Company L.P. Series B Preferred Units shall be redeemed prior to the OP Effective Time in accordance with the Company L.P. Partnership Agreement so that no Company L.P. Series B Preferred Units shall be outstanding at the OP Effective Time, and any security issued in connection with the redemption of the Company L.P. Series B Preferred Units shall be redeemed for cash prior to the OP Effective Time.

(d) If prior to the OP Effective Time, Parent L.P. or Company L.P., as the case may be, should split, combine or otherwise reclassify the Parent Common Units or the Company L.P. Units, or pay a non-cash dividend or other non-cash distribution in Parent Common Units, Parent Preferred Units or Company L.P. Units, as applicable, or make any other such non-cash dividend or non-cash distribution in interests of Parent L.P. or Company L.P. in respect of the Parent Common Units or the Company L.P. Units, respectively, then any number or amount contained herein which is based upon the number of Parent Common Units or Company L.P. Units, as the case may be (including but not limited to the OP Merger Consideration), will be appropriately adjusted to reflect such split, combination, dividend or other distribution or change.

(e) Prior to the OP Effective Time, the Parent L.P. Partnership Agreement shall be amended (which amendment shall be in form and substance (other than those terms set forth below in this Section 1.09(e)) reasonably acceptable to the Company) in accordance with Delaware law in order to create the Parent L.P. Preferred Interests, which will have the same economic terms as the Parent 6% Preferred Stock except that they shall be (i) convertible into Parent Common Units on the same terms, mutatis mutandis, as the Parent 6% Preferred Stock shall be convertible into Parent Common Stock and (ii) exchangeable for Parent 6% Preferred Stock; provided that in the case of each of clauses (i) and (ii) the holder of the Parent L.P. Preferred Interests shall be required to provide Parent and Parent L.P. with prior written notice and comply with certain other customary conditions prior to such exchange or conversion.

SECTION 1.10. Structure. Notwithstanding anything in this Agreement otherwise to the contrary, the Company shall cooperate with and agree to any reasonable changes requested by Parent regarding the structure of the transactions contemplated herein (such cooperation shall include entering into appropriate amendments to this Agreement) in order to enable Parent, Parent L.P. or Merger Sub to obtain a "step up" in the tax basis of the assets of the Company or any Company Subsidiary; provided that any such changes do not have an adverse effect on either the holders of the Company Common Stock or Company Common Units or jeopardize the qualifications of the REIT Merger as a taxable purchase of Company Common Stock and the OP Merger or any Company Common Unit Exchange as a contribution in which no gain or loss would be recognized pursuant to Section 721(a) of the Code.

SECTION 2.01. Exchange Fund. At or prior to the REIT Effective Time, Parent shall deposit with Mellon Investor Services or such other bank or trust company as Parent shall determine and who shall be reasonably satisfactory to the Company (the "Exchange Agent"): (i) in trust for the benefit of holders of shares of Company Common Stock, for exchange in accordance with Section 1.07(a), all the cash and certificates representing shares of Parent Common Stock and Parent 6% Preferred Stock to be paid or issued pursuant to this Agreement in exchange for outstanding Company Common Stock and cash sufficient to pay cash in lieu of fractional shares pursuant to Section 2.05 and (ii) in trust for the benefit of holders of shares of Company Series A Preferred Stock, for exchange in accordance with Section 1.07(b), all the certificates representing shares of Parent 8³/8% Preferred Stock to be issued pursuant to this Agreement in exchange for outstanding Company Series A Preferred Stock.

"Takeover Proposal" means any offer or proposal for any direct or indirect acquisition or purchase, in one transaction or a series of transactions, of 20% or more of the assets of the Company and the Subsidiaries of the Company, taken as a whole, or 20% or more in voting power of the outstanding shares of Company Common Stock or any class or series of equity or voting securities of the Company or any Significant Subsidiary (including without limitation the Company L.P. Units), any tender offer or exchange offer that if consummated would result in any Person beneficially owning 20% or more in voting power of the outstanding shares of Company Common Stock or any class or series of equity or voting securities of the Company or any Significant Subsidiary (including without limitation the Company L.P. Units), or any merger, consolidation, business combination, recapitalization, reclassification, share exchange, liquidation, dissolution or similar transaction or series of transactions involving the Company or any Significant Subsidiary.

(b) In addition to the obligations of the Company set forth in paragraph (a) of this Section 6.04, the Company shall notify Parent promptly (but in any event within 24 hours) after receipt or occurrence of (i) any Takeover Proposal, (ii) any request for information with respect to any Takeover Proposal, (iii) any inquiry, proposal, discussions or negotiation with respect to any Takeover Proposal, and (iv) the material terms and conditions of any such Takeover Proposal, request for information, inquiry, proposal, discussion or negotiation and the identity of the Person making any such Takeover Proposal, request for information, inquiry or proposal or with whom discussions or negotiations are taking place. The Company shall promptly keep Parent informed in all material respects of the status and details (including amendments or proposed amendments) of any such inquiry, request or Takeover Proposal.

(c) Nothing contained in this Section 6.04 shall prohibit the Company and the Company Board from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or (ii) making any disclosure to the Company's stockholders if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure so to disclose would be inconsistent with its obligations under applicable Law; provided, however, that, other than pursuant to Section 6.04(e), in no event shall the Company, the Company Board or any committee thereof withdraw (or modify in a manner adverse to Parent), or propose to withdraw (or modify in a manner adverse to Parent), its position with respect to this Agreement, the Voting Agreements, the

REIT Merger, the OP Merger or the other Transactions or adopt, approve or recommend, or propose to adopt, approve or recommend, a Takeover Proposal.

(d) Notwithstanding anything in this Section 6.04 to the contrary, prior to the REIT Effective Time, the Company may negotiate and participate in discussions and negotiations with such Person that has made an unsolicited bona fide written Takeover Proposal not resulting from or arising out of a breach of Section 6.04(a) (provided that the Company shall not agree to any exclusive right to negotiate with such Person) and may furnish information concerning its business, properties or assets to such Person pursuant to appropriate confidentiality agreements (on terms not less favorable to the Company than the Confidentiality Agreement); provided that the Company Board shall be permitted to take any such action if, and only if, prior to taking such action, the Company Board has determined by the affirmative vote of a majority of all of the members of the Company Board that (i) such Takeover Proposal would result in, or would reasonably be expected to result in, a Superior Proposal and (ii) after receiving advice from outside legal counsel, the failure to provide information to such Person or access or to engage in discussions or negotiations with such Person would be reasonably likely to cause the Company Board to breach its statutory duties to the Company under applicable Law. "Superior Proposal" means a Takeover Proposal (as defined in Section 6.04(a), except that the reference to "20%" in such definition shall be deemed to be a reference to "50%") whereby the Person making such proposal has on an unsolicited basis submitted a bona fide written proposal to the Company relating to any such transaction on terms that the Company Board determines in its good faith judgment (after consultation with a nationally recognized financial advisor, taking into account all the terms and conditions of the Takeover Proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation) are more favorable to the Company's stockholders, from a financial point of view, than this Agreement and the REIT Merger, taken as a whole, and that is reasonably capable of being completed. The Company shall not provide any nonpublic information, which was not previously provided to Parent, regarding the Company to any other Person pursuant to this Section 6.04(d) unless such information is simultaneously provided to Parent.

(e) If the Company Board, after consultation with outside legal counsel, determines that failure to accept a Superior Proposal would likely cause a breach of the statutory duties of the directors of the Company to the Company under applicable Law, the Company Board may inform the holders of Company Common Stock that it no longer believes that the REIT Merger is advisable and no longer recommends approval (a "Subsequent Determination"), but only at a time that is prior to the Company Stockholders Meeting and after the second business day following Parent's receipt of written notice advising Parent that the Company has received a Superior Proposal specifying the terms and conditions of such Superior Proposal (and including a copy thereof with all accompanying documentation), identifying the Person making such Superior Proposal and stating that it is considering a Subsequent Determination; provided, that (i) during such two business day period Parent does not make an offer that the Board of Directors of the Company shall have reasonably concluded in good faith (following consultation with its nationally recognized financial advisors and outside counsel) is as favorable to the stockholders of the Company as such Superior Proposal and (ii) at the end of such two business day period such Takeover Proposal continues to be a Superior Proposal. At any time after the two business day period following notification to Parent of the Company's consideration to do so and if the Company has otherwise complied with the terms of this Section 6.04 (but in no event following adoption of this Agreement at the Company Stockholders Meeting), the Company may terminate this Agreement pursuant to Section 8.01(e) and enter into an agreement with respect to the Superior Proposal; provided that prior to such termination the Company shall have made payment to Parent of the full amounts, if any, required under Sections 8.03(c) and (d) to be paid at that time.

SECTION 6.05. Benefit Plans. (a) Until at least December 31, 2006, Parent shall provide or cause the Surviving Company to provide benefits to the employees of the Company as of the date of this Agreement who continue to be employed by the Surviving Company (such employees, the

"Continuing Employees") that, taken as a whole, are substantially comparable in the aggregate to such employees to those provided to such employees by the Company and its Subsidiaries as of the date hereof and thereafter comparable to similarly situated employees of Parent.

(b) From and after the Effective Time, Parent shall, and shall cause the Surviving Company to, honor in accordance with their respective terms (as in effect on the date of this Agreement) all the Company Employment Agreements in Section 3.15(c) of the Company Disclosure Letter.

(c) Parent will honor in accordance with their terms, all vested accrued benefit obligations to, and contractual rights of, current and former employees of the Company and its Subsidiaries which are disclosed on the Company's Disclosure Letter, including the recently instituted severance policy set forth in Section 6.05(c) of the Company Disclosure Letter. Parent acknowledges that a "change of control" within the meaning of the Company Option Plans will occur on the Effective Time and that as a result all vesting of unvested options will be accelerated and all of them will vest. The Company may make any required employee matching contributions under its 401(k) Plan in a manner consistent with historical practices.

(d) With respect to any "employee benefit plan", as defined in Section 3(3) of ERISA, maintained by Parent or any of its Subsidiaries, to the extent such plan is made available to an employee of the Company, for all purposes (other than benefit accrual), service with the Company shall be treated as service with Parent or any of its Subsidiaries as applicable; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits; and provided further that (i) the Continuing Employees who participate in the severance plan shall not be eligible to participate in Parent's employee severance plan until January 1, 2007 and then only to the extent provided under the Company severance policy and (ii) upon commencing participation in Parent's employee severance plan, the Continuing Employees shall be credited for prior service with the Company for purposes of determining their entitlements to severance benefits.

(e) Parent shall waive, or cause to be waived, any pre-existing condition limitation under any welfare benefit plan maintained by Parent or any of its Affiliates (other than the Company) in which employees of the Company (and their eligible dependents) will be eligible to participate from and after the Effective Time, except to the extent that such pre-existing condition limitation would have been applicable under the comparable Company welfare benefit plan immediately prior to the Effective Time. Parent shall recognize, or cause to be recognized, the dollar amount of all expenses incurred by each Company employee (and his or her eligible dependents) during the calendar year in which the Effective Time occurs for purposes of satisfying such year's deductible and co-payment limitations under the relevant welfare benefit plans in which they will be eligible to participate from and after the Effective Time.

(f) All amounts earned by Company employees under the Company's Long-Term Executive Incentive Plan (the "LTIP") shall be payable in accordance with the terms set forth under the heading "Chelsea Property Group, Inc. 2002-2006 Long-Term Executive Incentive Plan Payment Schedule" in Section 6.05(f) of the Company Disclosure Letter. No additional amounts shall thereafter be earned or payable under the LTIP.

(g) The Company shall take all actions necessary and appropriate to ensure that (i) the Stock Purchase Plan is terminated prior to the REIT Effective Time, and that no Company employee shall thereafter have any rights under the Stock Purchase Plan, (ii) participation in the Stock Purchase Plan is suspended as of the end of the first "Option Period" (as defined in the Stock Purchase Plan) that occurs following the date of this Agreement and (iii) prior to the REIT Effective Time, participants in the Company's 401(k) Plan will no longer have the right to purchase shares of Company Common Stock through such plan.

(h) Except as otherwise expressly provided in this Agreement, nothing contained in this Section 6.05 or elsewhere in this Agreement shall be construed to prevent, from and after the Effective Time, the termination of employment of any individual employee of the Company or any change in the employee benefits available to any such individual employee or the amendment or termination of any particular Company Employee Benefit Plan or other employee benefit plan, program, policy or arrangement.

(i) Parent and the Company shall cooperate in good faith and take such reasonable steps as may be necessary or appropriate to ensure, to the extent reasonably practicable, that payments made to Company employees in connection with the REIT Merger and/or the OP Merger, or upon subsequent termination of employment, will not be treated as "excess parachute payments" under Section 280G of the Code.

SECTION 6.06. Indemnification. (a) Parent and Merger Sub agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors or officers of the Company as provided in the Company Organizational Documents shall be assumed by the Surviving Company in the REIT Merger, without further action, at the REIT Effective Time and shall survive the REIT Merger and shall continue in full force and effect in accordance with their terms.

(b) The Surviving Company shall (i) for a period of six years after the REIT Effective Time cause to be maintained in effect in the Surviving Company's (or any successor) articles of incorporation and by-laws (or similar governing documents), provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses which are no less advantageous to the intended beneficiaries as those currently contained in the articles of incorporation and by-laws of the Company and (ii) maintain for a period of at least six years the current policies of directors' and officers' liability insurance maintained by the Company (provided that the Surviving Company may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured) with respect to claims arising from facts or events that occurred on or before the REIT Effective Time; including, without limitation, in respect of the transactions contemplated by this Agreement; provided, however, that in no event shall the Surviving Company be required to expend in any one year an amount in excess of 200% of the annual premiums currently paid by the Company for such insurance; and, provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Surviving Company shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. The provisions of this subsection (b) shall be deemed to have been satisfied if prepaid policies have been obtained by the Surviving Company for purposes of this Section 6.06, which policies (together with the Company's existing policy) provide such directors and officers with the coverage described in this subsection (b) for an aggregate period of not less than six years with respect to claims arising from facts or events that occurred on or before the REIT Effective Time, including, without limitation, in respect of the transactions contemplated by this Agreement.

(c) If the Surviving Company or any of its successors or assigns (i) consolidates with or merges with or into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Surviving Company assume the obligations set forth in this Section 6.06. The parties acknowledge and agree that to the extent the Surviving Company fails to comply with its indemnification obligations pursuant to this Section 6.06, Parent shall fulfill the obligations of the Surviving Company hereunder.

(d) The provisions of this Section 6.06 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.06 applies without the consent of such affected

indemnitee and are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her legal representatives.

SECTION 6.07. Public Announcements. Each of Parent, on the one hand, and the Company, on the other hand, shall consult with each other before issuing, and provide each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the OP Merger, the REIT Merger and the other Transactions and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow each other party reasonable time to comment on such release or announcement in advance of such issuance, it being understood that the final form and content of any such release or announcement, to the extent so required, shall be at the final discretion of the disclosing party.

SECTION 6.08. Transfer Taxes. Parent and the Company shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer or stamp taxes, any transfer, recording, registration and other fees and any similar taxes that become payable in connection with the transactions contemplated by this Agreement (together with any related interests, penalties or additions to tax, "Transfer Taxes"), and shall cooperate in attempting to minimize the amount of Transfer Taxes. From and after the Effective Time, the Surviving Company shall pay or cause to be paid, without deduction or withholding from any consideration or amounts payable to holders of the Company Common Stock, Company Series A Preferred Stock, Company L.P. Units and/or Company Options, all Transfer Taxes.

SECTION 6.09. Listing of Shares. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock and the Parent 6% Preferred Stock to be issued in the REIT Merger and the shares of Parent Common Stock to be reserved for issuance upon exercise of Company Options to be approved for listing, upon official notice of issuance, on the NYSE.

SECTION 6.10. Affiliate Letter. On or prior to the date of the Company Stockholders Meeting, the Company will deliver to Parent a letter (the "Company Affiliate Letter") identifying all persons who are "affiliates" of the Company for purposes of Rule 145 under the Securities Act ("Rule 145"). On or prior to the Closing Date, the Company will use all reasonable efforts to cause each person identified as an "affiliate" in the Company Affiliate Letter to deliver a written agreement, in form and substance reasonably acceptable to Parent, in connection with restrictions on affiliates under Rule 145.

SECTION 6.11. Coordination of Dividends.

(a) From and after the date of this Agreement, the Company shall not make any dividend or distribution to its stockholders, and Company L.P. shall not make any dividend or distribution to its partners, in each case without the prior written consent of Parent in its sole discretion; provided, however, that the written consent of Parent shall not be required for the authorization and payment of (i) distributions required for the Company to maintain its status as a REIT under the Code; (ii) quarterly distributions of up to $0.60 per share of Company Common Stock per quarter to the holders thereof for the quarter ending June 30, 2004 (the "Initial Dividend") and for each quarter thereafter ending prior to the REIT Effective Time; provided that the record and payment dates for each distribution with respect to the Company Common Stock pursuant to this clause (ii) (other than the Initial Dividend) shall be the same date as the record and payment dates for the quarterly distributions for the Parent Common Stock, as provided by Parent to the Company by written notice not less than twenty (20) business days prior to the record date for each such quarterly Parent distribution; (iii) a distribution per Company Common Unit in the same amount as a dividend per share of Company Common Stock permitted pursuant to clauses (i) or (ii) above or Section 6.11(b),

The dividend of each shall be equal to such party's most recent quarterly dividend rate, multiplied by the number of days elapsed since the last dividend record date through and including the REIT Effective Time, and divided by the actual number of days in the calendar quarter in which such dividend is declared.

In the event that a distribution with respect to the Company Common Stock and the Company Series A Preferred Stock permitted by this Section 6.11 (including pursuant to Section 6.11(b) above) has (i) a record date prior to the REIT Effective Time and (ii) has not been paid as of the REIT Effective Time, the holders of Company Common Stock and Company Series A Preferred Stock shall be entitled to receive such distribution from the Company at the time such shares are exchanged pursuant to Article II of this Agreement.

Interests in exchange for Company Common Units, and of options to purchase shares of Parent Common Stock in exchange for options to purchase Company Common Stock, in each case pursuant to the transactions contemplated hereby and to the extent such securities are listed in the Company Section 16 Information, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act in accordance with Rule 16b-3 and interpretations of the SEC thereunder.

As used in this Agreement, the "Termination Fee" shall be an amount equal to the lesser of (x) $110,000,000 (the "Base Amount") and (y) the sum of (A) the maximum amount that can be paid to Parent without causing Parent to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code ("Qualifying Income"), as determined by independent accountants to Parent, and (B) in the event Parent receives and, prior to the date the Termination Fee is due to be paid to Parent as described above, provides a copy to the Company of, an opinion or a letter from outside counsel (the "Termination Fee Tax Opinion") indicating that Parent has received an opinion of counsel or a ruling from the IRS holding that Parent's receipt of the Base Amount would either constitute Qualifying Income or would be excluded from gross income of Parent within the meaning of Sections 856(c)(2) and (3) of the Code (the "REIT Requirements"), the Base Amount less the amount payable under clause (A) above. In the event that Parent is not able to receive the full Base Amount on the date the Termination Fee is due as described above, the Company shall place the amount by which the Base Amount exceeds the amount paid under clause (y)(A) of the preceding sentence above (the "Unpaid Base Amount") in escrow and shall not release any portion thereof to Parent unless and until Parent provides the Company with either one of the following: (A) a letter from Parent's independent accountants indicating the maximum portion of the Unpaid Base

Amount that can be paid at that time to Parent without causing Parent to fail to meet the REIT Requirements or (B) a Termination Fee Tax Opinion, in either of which events the Company shall pay to Parent from the escrow the lesser of the Unpaid Base Amount and, if applicable, the maximum amount stated in the accountants' letter referred to in clause (A) of this sentence. The Company's obligation to pay any portion of the Unpaid Base Amount shall terminate three (3) years from the date of this Agreement. Amounts remaining in escrow after such obligation terminates shall be released to the Company.

(e) The Company and Parent agree that the agreements contained in Section 8.03(d) above are an integral part of the transactions contemplated by this Agreement, and that the payments to be made thereunder shall be compensation for the loss suffered by the applicable party as a result of the failure of the REIT Merger to be consummated and constitute liquidated damages and not a penalty.

SECTION 8.04. Amendment. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective boards of directors or managers (or other similar entity, as the case may be), at any time before or after approval of the matters presented in connection with the REIT Merger by the stockholders of the Company or the OP Merger by the limited partners of Company L.P., but, after any such approval, no amendment shall be made which by law or in accordance with the rules of the relevant stock exchange requires further approval by such stockholders, partners or members without such further approval.

At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective boards of directors or managers (or other similar entity, as the case may be), may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions contained herein.

The term "or" is not exclusive. The word "extent" in the phrase "to the extent" shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply "if". The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms.

SECTION 9.07. Entire Agreement; No Third-Party Beneficiaries. The Transaction Documents (including the exhibits and schedules thereto), taken together with the Company Disclosure Letter, the Tax Protection Agreement, the Put Agreement, the employment agreements attached as Exhibit C hereto and the Confidentiality Agreement, (a) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the Transactions. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Sections 6.05 and 6.06 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

SECTION 9.08. Governing Law. This Agreement shall be governed by, and. construed in accordance with, the laws of the State of Maryland, regardless of the laws that might otherwise govern under applicable conflict or choice of law rules.

Merger Sub may assign, in its sole discretion, any of or all its rights, interests and obligations under this Agreement to Parent L.P. or to any direct or indirect wholly owned Subsidiary of Parent L.P., but no such assignment shall relieve Parent, Parent L.P., Merger Sub or L.P. Merger Sub of any of its obligations under this Agreement. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

SECTION 9.10. Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of the United States located in the State of New York or in any New York state court, this being in addition to any other remedy to which they are entitled at law or in equity.

(iii) any amendment of the Company Organizational Documents, which amendment would result in a breach of a representation, warranty or covenant of the Company under the Merger Agreement or would in any manner prevent or materially impede, interfere with or delay the REIT Merger, the OP Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement or (iv) any other matter that is inconsistent with the prompt consummation of the REIT Merger, the OP Merger and the other transactions contemplated by the Merger Agreement (each of clauses (i), (ii), (iii) and (iv), a "Competing REIT Transaction").

(c) Certain Permitted Conversions. Notwithstanding anything to the contrary contained herein: (i) at any time from and after the date hereof and prior to Company L.P. obtaining the OP Merger Approval, Holder shall be entitled to convert its Company Common Units into Company Common Stock in accordance with the Company L.P. Partnership Agreement and the Company Organizational Documents; provided, however, that Holder shall not be entitled to convert any Company Common Units into Company Common Stock that, if so converted, would, when combined with all other conversions of Company Common Units into Company Common Stock by any holder of Company Common Units during such period, result in Parent and Parent L.P. having secured the affirmative vote of less than 50.1% of the Company Common Units entitled to vote on the Merger Agreement and the OP Merger pursuant to this Agreement and the additional Voting Agreements entered into by Parent and Parent L.P. with the other Principal Company Limited Partners; and (ii) at any time after Company L.P. shall have obtained the OP Merger Approval, Holder shall be entitled to convert its Company Common Units into Company Common Stock in accordance with the Company L.P. Partnership Agreement and the Company Organizational Documents. Any shares of Company Common Stock issued to Holder in accordance with this Section 1.4(c) shall be deemed to be Company Shares for the purpose of this Agreement from and after the date of such conversion and as a result such Holder shall be entitled to receive the REIT Merger Consideration in the REIT Merger (and not the OP Merger Consideration in the OP Merger) with respect to such shares of Company Common Stock so converted into Company Common Units.

Section 1.8. No Solicitation. (a) Holder shall not, and shall use its reasonable best efforts to cause its Affiliates or Representatives not to, directly or indirectly (i) solicit, initiate, encourage or take any other action to facilitate (including by the furnishing of information) the submission of any inquiry, proposal or offer from any Person (other than Parent, Merger Sub or their Affiliates) relating to, or that could reasonably be expected to lead to, any Takeover Proposal, (ii) agree to, approve or recommend any Takeover Proposal or enter into any agreement with respect to any Takeover Proposal or (iii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or could reasonably be expected to lead to, any Takeover Proposal; provided, however, that the foregoing does not restrict any Holder that is a member of the Company Board or an officer of the Company from taking any actions in such capacity to the extent permitted by the Merger Agreement.

(b) In addition to the obligations of Holder set forth in paragraph (a) of this Section 1.8, Holder shall notify Parent promptly (but in any event within 24 hours) after receipt or occurrence of (i) any Takeover Proposal, (ii) any request for information with respect to any Takeover Proposal, (iii) any inquiry, proposal, discussions or negotiation with respect to any Takeover Proposal and (iv) the material terms and conditions of any such Takeover Proposal, request for information, inquiry, proposal, discussion or negotiation and the identity of the Person making any such Takeover Proposal, request for information, inquiry or proposal or with whom discussions or negotiations are taking place.
