Ladies and Gentlemen:

Each of Mack-Cali Realty, L.P., a Delaware limited partnership (the "Operating Partnership"), and Mack-Cali Realty Corporation, a Maryland corporation qualified as a real estate investment trust and the general partner of the Operating Partnership (the "Company"), hereby confirms its agreement with the several underwriters named in Schedule 2 hereto (the "Underwriters"), for whom you have been duly authorized to act as representatives (in such capacities, the "Representatives"), as set forth below. If you are the only Underwriters, all references herein to the Representatives shall be deemed to be to the Underwriters.

1. Securities. Subject to the terms and conditions herein contained, the Operating Partnership proposes to issue and sell to the several Underwriters certain securities of the Operating Partnership identified in Schedule 1 hereto (the "Securities").

2. Representations and Warranties of the Company. Each of the Company and the Operating Partnership represents and warrants to, and agrees with, each of the several Underwriters that:

(a) Each of the Operating Partnership and the Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the "Act"). A registration statement (the file number of which is set forth in Schedule 1 hereto) on such Form with respect to the Securities, including a base prospectus, has been filed by the Operating Partnership and the Company with the Securities and Exchange Commission (the "Commission") under the Act, and one or more amendments to such registration statement may also have been so filed. Such registration statement, as so amended, has been declared by the Commission to be effective under the Act and no stop orders suspending the effectiveness of such registration statement have been issued under the Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Operating Partnership or the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. Such registration statement, as amended at the date of this Agreement as specified in Schedule 1 hereto, meets the requirements set forth in Rule

415(a)(1)(x) under the Act and complies in all other material respects with said Rule. The Operating Partnership will next file with the Commission either (A) if the Operating Partnership relies on Rule 434 under the Act, a Term Sheet (as hereinafter defined) relating to the Securities, that shall identify the Preliminary Prospectus (as hereinafter defined) that it supplements and, if required to be filed pursuant to Rules 434(c)(2) and 424(b), an Integrated Prospectus (as hereinafter defined), in either case, containing such information as is required or permitted by Rules 434, 430A, and 424(b) under the Act or (B) if the Operating Partnership does not rely on Rule 434 under the Act, pursuant to Rule 424(b) under the Act a final prospectus supplement to the base prospectus included in such registration statement, as so amended, describing the Securities and the offering thereof, in such form as has been provided to, or discussed with, and approved by the Representatives as provided in section 4(a) of this Agreement. As used in this Agreement, the term "Registration Statement" means such registration statement, as amended at the time when it was declared effective, including (i) all financial schedules and exhibits thereto, (ii) all documents incorporated by reference or deemed to be incorporated by reference therein and (iii) any information omitted therefrom pursuant to Rule 430A under the Act and included in the Prospectus (as hereinafter defined) or, if required to be filed pursuant to Rules 434(c)(2) and 424(b), in the Integrated Prospectus; the term "Base Prospectus" means the prospectus included in the Registration Statement; the term "Preliminary Prospectus" means any preliminary form of the Prospectus (as defined herein) specifically relating to the Securities, in the form first filed with, or transmitted for filing to, the Commission pursuant to Rule 424 under the Act; the term "Prospectus Supplement" means any prospectus supplement specifically relating to the Securities, in the form first filed with, or transmitted for filing to, the Commission pursuant to Rule 424 under the Act; the term "Prospectus" means: (A) if the Operating Partnership relies on Rule 434 under the Act, the Term Sheet relating to the Securities that is first filed pursuant to Rule 424(b)(7) under the Act, together with the Preliminary Prospectus identified therein that such Term Sheet supplements; (B) if the Operating Partnership does not rely on Rule 434 under the Act, the Preliminary Prospectus; or (C) if the Operating Partnership does not rely on Rule 434 under the Act and if no prospectus is required to be filed pursuant to Rule 424 under the Act, the Base Prospectus, including, in each case, the Prospectus Supplement; "Base Prospectus," "Prospectus," "Preliminary Prospectus" and "Prospectus Supplement" shall include in each case the documents, if any, filed by the Operating Partnership with the Commission pursuant to the United States Securities Exchange Act of 1934, as amended (the "Exchange Act"), and incorporated by reference therein; the term "Integrated Prospectus" means a prospectus first filed with the Commission pursuant to Rules 434(c)(2) and 424(b) under the Act; and the term "Term Sheet" means any abbreviated term sheet that satisfies the requirements of Rule 434 under the Act. Any reference in this Agreement to an "amendment" or "supplement" to any Preliminary Prospectus, the Prospectus, or any Integrated Prospectus or an "amendment" to any registration statement (including the Registration Statement) shall be deemed to include any document incorporated by reference therein that is filed with the Commission under the Exchange Act after the date of such Preliminary Prospectus, Prospectus, Integrated Prospectus or registration statement, as the case may be. For purposes of the preceding sentence, any reference to the "effective date" of an amendment to a registration statement shall, if such amendment

is effected by means of the filing with the Commission under the Exchange Act of a document incorporated by reference in such registration statement, be deemed to refer to the date on which such document was so filed with the Commission; any reference herein to the "date" of a Prospectus that includes a Term Sheet shall mean the date of such Term Sheet.

(b) The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus. When any Preliminary Prospectus was filed with the Commission it (i) contained all statements required to be stated therein in accordance with, and complied in all material respects with the requirements of, the Act, the Exchange Act and the respective rules and regulations of the Commission thereunder and (ii) did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(a) The Operating Partnership will file the Prospectus or any Term Sheet that constitutes a part thereof, any Integrated Prospectus or the Prospectus Supplement, as the case may be, and any amendment or supplement thereto with the Commission in the manner and within the time period required by Rules 434 and 424(b) under the Act. During any time when a prospectus relating to the Securities is required to be delivered under the Act, the Operating Partnership (i) will comply with all requirements imposed upon it by the Act and the Exchange Act and the respective rules and regulations of the Commission thereunder to the extent necessary to permit the continuance of sales of or dealings in the Securities in accordance with the provisions hereof and of the Prospectus and any Integrated Prospectus, as then amended or supplemented, and (ii) will not file with the Commission the Prospectus, Term Sheet, any Integrated Prospectus or any amendment or supplement thereto or any amendment to the Registration Statement of which the Representatives shall not previously have been advised and furnished with a copy for a reasonable period of time prior to the proposed filing and as to which filing the Representatives shall not have given their consent. The Operating Partnership will prepare and file with the Commission, in accordance with the rules and regulations of the Commission, promptly upon request by the Representatives or counsel for the Underwriters, any amendment to the Registration Statement or amendment or supplement to the Prospectus and any Integrated Prospectus that may be necessary or advisable in connection with the distribution of the Securities by the several Underwriters, and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective by the Commission as promptly as possible.

(c) If required by applicable law, the Operating Partnership will arrange for the qualification of the Securities and any Underlying Securities for offering and sale under the securities or blue sky laws of such jurisdictions as the

Representatives may designate and will continue such qualifications in effect for as long as may be necessary to complete the distribution of the Securities and any Underlying Securities; provided, however, that in connection therewith the Operating Partnership shall not be required to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction.

(d) If at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus or any Integrated Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it is necessary at any time to amend or supplement the Prospectus or any Integrated Prospectus to comply with the Act or Exchange Act or the respective rules or regulations of the Commission thereunder, the Operating Partnership will promptly notify the Representatives thereof and, subject to Section 4(a) of this Agreement, will prepare and file with the Commission, at the Operating Partnership's expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus and any Integrated Prospectus that corrects such statement or omission or effects such compliance.

(f) The Operating Partnership, as soon as practicable, will make generally available to its securityholders and to the Representatives a consolidated earning statement of the Operating Partnership and its subsidiaries that satisfies the provisions of Section 11(a) of the Act and Rule 158 thereunder.

(h) The Operating Partnership will not, directly or indirectly, (i) take any action designed to cause or to result in, or that has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Operating Partnership to facilitate the sale or resale of the Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation for soliciting purchases of the Securities or (B) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Operating Partnership.

(i) If at any time during the 25-day period after the Registration Statement becomes effective, any rumor, publication or event relating to or affecting the Operating Partnership shall occur as a result of which in your opinion the market price of the Securities has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus or any Integrated Prospectus), the Operating Partnership will, after written notice from you advising the Operating Partnership to the effect set forth above, forthwith prepare, consult with you concerning the substance of, and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event.

(j) If required as set forth in Schedule 1 hereto, the Operating Partnership will cause the Securities and any Underlying Securities to be duly authorized for listing by the New York Stock Exchange.

(k) The Company will continue to use its best efforts to meet the requirements to qualify as a REIT under the Code.

The Operating Partnership will pay all costs and expenses incident to the performance of its obligations under this Agreement, whether or not the transactions contemplated herein are consummated or this Agreement is terminated pursuant to Section 10 hereof, including all costs and expenses incident to (i) the printing or other production of documents with respect to the transactions, including any costs of printing the registration statement originally filed with respect to the Securities and any amendment thereto, any Preliminary Prospectus, the Prospectus and any Integrated Prospectus and any amendment or supplement thereto, this Agreement, the Securities Documents and any blue sky memoranda, (ii) all arrangements relating to the delivery to the Underwriters of copies of the foregoing documents, (iii) the fees and disbursements of counsel, accountants and any other experts or advisors retained by the Operating Partnership and the Company, (iv) preparation, issuance and delivery to the Underwriters of any certificates evidencing the Securities, including the fees and expenses of the transfer agent, exchange agent or registrar, (v) the qualification, if any, of the Securities and any Underlying Securities under state securities and blue sky laws and real estate syndication laws, including filing fees and fees and disbursements of counsel for the Underwriters relating thereto and relating to the preparation of any blue sky memoranda, (vi) the filing fees of the Commission relating to the Securities, (vii) any listing of the Securities and Underlying Securities on the New York Stock Exchange, (viii) any meetings with prospective investors in the Securities arranged by the Operating Partnership (other than as shall have been specifically approved by the Representatives to

be paid for by the Underwriters) and (ix) advertising relating to the offering of the Securities requested by the Operating Partnership (other than as shall have been specifically approved by the Representatives to be paid for by the Underwriters). If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 of this Agreement is not satisfied, because this Agreement is terminated pursuant to Section 10 of this Agreement or because of any failure, refusal or inability on the part of the Operating Partnership or the Company to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder other than by reason of a default by any of the Underwriters, the Operating Partnership will reimburse the Underwriters severally upon demand for all out-of-pocket expenses (including counsel fees and disbursements) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

(i) they are independent registered public accountants with respect to the Operating Partnership, the Company and their subsidiaries within the meaning of the Act, the Exchange Act and the applicable published rules and regulations thereunder;

(ii) in their opinion, the financial statements audited by them and incorporated by reference in the Registration Statement, the Prospectus and any Integrated Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act, the Exchange Act and the related published rules and regulations thereunder;

(iii) on the basis of a reading of the minute books of the shareholders, the board of directors, partners and any committees thereof of the Operating Partnership, the Company and each of their consolidated subsidiaries, and inquiries of certain officials of the Operating Partnership, the Company and their consolidated subsidiaries who have responsibility for financial and accounting matters, nothing came to their attention that caused them to believe that:

(A) (i) any unaudited consolidated condensed financial statements of the Operating Partnership, the Company and their consolidated subsidiaries included in the Registration Statement, the Prospectus and any Integrated Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Act, the Exchange Act and the related published rules and regulations thereunder, or (ii) any material modification should be made to the unaudited consolidated condensed financial statements for them to be in conformity with generally accepted accounting principles; and

(B) at a specific date not more than five business days prior to the date of such letter, there were any changes in the partners' capital or increase in mortgages and loans payable of the Operating Partnership and its consolidated subsidiaries, in each case compared with amounts shown on the most recent consolidated balance sheet included in the Registration Statement, the Prospectus and any Integrated Prospectus, except for such changes set forth in such letter;

(iv) they have carried out certain specified procedures, not constituting an audit, with respect to certain amounts, percentages and financial information that are derived from the general accounting records of the Operating Partnership, the Company and their consolidated subsidiaries and are included in the Registration Statement, the Prospectus and any Integrated Prospectus and in Exhibit 12 to the Registration Statement, including the information included or incorporated in the Operating Partnership's and the Company's most recent Annual Report on Form 10-K under the captions "Business" (Item 1), "Selected Financial Data" (Item 6) and "Management's Discussion and Analysis of Financial Condition and Results of Operations" (Item 7) and the information included or incorporated in the Operating Partnership's and the Company's Quarterly Reports on Form 10-Q under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations," and have compared such amounts, percentages and financial information with such records and with information derived from such records and have found them to be in agreement, excluding any questions of legal interpretation; and

(v) on the basis of a reading of any unaudited pro forma consolidated condensed financial statements included in the Registration Statement, the Prospectus and any Integrated Prospectus, carrying out certain specified procedures that would not necessarily reveal matters of significance with respect to the comments set forth in this paragraph (v), inquiries of certain officials of the Operating Partnership, the Company, their consolidated subsidiaries and any acquired Company who have responsibility for financial and accounting matters and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the unaudited pro forma consolidated condensed financial statements, nothing came to their attention that

caused them to believe that the unaudited pro forma consolidated condensed financial statements do not comply in form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements.

In the event that the letters referred to above set forth any such changes, decreases or increases, it shall be a further condition to the obligations of the Underwriters that (A) such letters shall be accompanied by a written explanation of the Company as to the significance thereof, unless the Representatives deem such explanation unnecessary, and (B) such changes, decreases or increases do not, in the sole judgment of the Representatives, make it impractical or inadvisable to proceed with the purchase and delivery of the Securities as contemplated by the Registration Statement.

References to the Registration Statement, the Prospectus and any Integrated Prospectus in this paragraph (e) with respect to either letter referred to above shall include any amendment or supplement thereto at the date of such letter.

(f) The Representatives shall have received a certificate, dated the Closing Date, of the chief executive officer or an executive vice president and the chief financial or accounting officer of the Company, as the general partner of the Operating Partnership, to the effect that:

(i) the representations and warranties of the Operating Partnership and the Company in this Agreement are true and correct as if made on and as of the Closing Date; the Registration Statement, as amended as of the Closing Date, does not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading, and the Prospectus or any Integrated Prospectus, as amended or supplemented as of the Closing Date, does not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Operating Partnership and the Company have performed all covenants and agreements and satisfied all conditions on their part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto and no order directed at any document incorporated by reference in the Registration Statement, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto has been issued, and no proceedings for that purpose have been instituted or threatened or, to the best of the Operating Partnership's knowledge, are contemplated by the Commission; and

(iii) subsequent to the respective dates as of which information is given in the Registration Statement, the Prospectus and any Integrated Prospectus, none of the Operating Partnership, the Company nor any of their subsidiaries has sustained any material loss or interference with their respective businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any labor dispute or any legal or governmental proceeding, and there has not been any material adverse change, or any development involving a prospective material adverse change, in the condition (financial or otherwise), management, business, prospects, net worth or results of operations of the Operating Partnership, the Company or any of their subsidiaries, except in each case as described in or contemplated by the Prospectus or any Integrated Prospectus (exclusive of any amendment or supplement thereto).

(g) On or before the Closing Date, the Representatives and counsel for the Underwriters shall have received such further certificates, documents or other information as they may have reasonably requested from the Operating Partnership or the Company.

(h) If applicable, prior to the commencement of the offering of the Securities, the Securities and any Underlying Securities shall have been approved for listing on the New York Stock Exchange, subject to official notice of issuance.

(i) subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading in the rating of any debt securities or preferred stock of the Operating Partnership or the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of the Operating Partnership or the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating).

All opinions, certificates, letters and documents delivered pursuant to this Agreement will comply with the provisions hereof only if they are reasonably satisfactory in all material respects to the Representatives and counsel for the Underwriters. The Operating Partnership shall furnish to the Representatives such conformed copies of such opinions, certificates, letters and documents in such quantities as the Representatives and counsel for the Underwriters shall reasonably request.

7. Indemnification and Contribution. (a) The Company and the Operating Partnership agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon:

(i) any untrue statement or alleged untrue statement made by the Company and the Operating Partnership in Section 2 of this Agreement,

(ii) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement or any amendment thereto or any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto or (B) any application or other document, or any amendment or supplement thereto, executed by the Company or the Operating Partnership or based upon written information furnished by or on behalf of the Company or the Operating Partnership filed in any jurisdiction in order to qualify the Securities under the securities or blue sky laws thereof or filed with the Commission or any securities association or securities exchange (each an "Application"),

(iii) the omission or alleged omission to state in the Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto, or any Application a material fact required to be stated therein or necessary to make the statements therein not misleading, or

(iv) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials used in connection with the marketing of the Securities, including, without limitation, slides, videos, films and tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Company and the Operating Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto, or any Application in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by such Underwriter through the Representatives specifically for use therein. This indemnity agreement will be in addition to any liability which the Company or the Operating Partnership may otherwise have. The Company or the Operating Partnership will not, without the prior written consent of the Underwriter or Underwriters purchasing, in the aggregate, more than 50% of the Securities, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not any such Underwriter or any person who controls any such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent includes an unconditional release of all of

the Underwriters and such controlling persons from all liability arising out of such claim, action, suit or proceeding.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company and the Operating Partnership, each of its directors, each of its officers who signed the Registration Statement, as amended at the date of this Agreement as specified in Schedule 1 hereto, and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company, the Operating Partnership or any such director, officer or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, as amended at the date of this Agreement as specified in Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto, or any Application or (ii) the omission or the alleged omission to state therein a material fact required to be stated in the Registration Statement, as amended at the date of this Agreement as specified in Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any amendment or supplement thereto, or any Application or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by such Underwriter through the Representatives specifically for use therein; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Company, the Operating Partnership or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or any action in respect thereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense

of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Representatives in the case of paragraph (a) of this Section 7, representing the indemnified parties under such paragraph (a) who are parties to such action or actions) or (ii) the indemnifying party does not promptly retain counsel satisfactory to the indemnified party or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party.

(d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Operating Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Company or the Operating Partnership, as the case may be, bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Operating Partnership or the Underwriters, the parties' relative intents, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Operating

Partnership and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to above in this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Underwriter shall be obligated to make contributions hereunder that in the aggregate exceed the total public offering price of the Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages that such Underwriter has otherwise been required to pay in respect of the same or any substantially similar claim, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute hereunder are several in proportion to their respective underwriting obligations and not joint. For purposes of this paragraph (d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each partner of the Operating Partnership, each officer of the Operating Partnership or the Company who signed the Registration Statement as amended at the date of this Agreement as specified in Schedule 1 hereto and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and the Operating Partnership.

8. Default of Underwriters. If one or more Underwriters default in their obligations to purchase Securities hereunder and the aggregate number of such Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase is ten percent or less of the aggregate number of Securities to be purchased by all of the Underwriters at such time hereunder, the other Underwriters may make arrangements satisfactory to the Representatives for the purchase of such Securities by other persons (who may include one or more of the non-defaulting Underwriters, including the Representatives), but if no such arrangements are made by the Closing Date the other Underwriters shall be obligated severally in proportion to their respective commitments hereunder to purchase the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If one or more Underwriters so default with respect to an aggregate number of Securities that is more than ten percent of the aggregate number of Securities, as the case may be, to be purchased by all of the Underwriters at such time hereunder, and if arrangements satisfactory to the Representatives are not made within 36 hours after such default for the purchase by other persons (who may include one or more of the non-defaulting Underwriters, including the Representatives) of the Securities with respect to which such default occurs, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Operating Partnership other than as provided in Section 9 hereof. In the event of any default by one or more Underwriters as described in this Section 8, the Representatives shall have the right to postpone the Closing Date, established as provided in Section 3 of this Agreement for not more than seven business days in order that any necessary changes may be made in the arrangements or documents for the purchase and delivery of the Securities. As used in this Agreement, the term "Underwriter" includes any person substituted for an

Underwriter under this Section 8. Nothing herein shall relieve any defaulting Underwriter from liability for its default.

9. Survival. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company and the Operating Partnership, their officers and the several Underwriters set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Operating Partnership, the Company, any of its officers or directors, any Underwriter or any controlling person referred to in Section 7 hereof and (ii) delivery of and payment for the Securities. The respective agreements, covenants, indemnities and other statements set forth in Sections 5 and 7 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

10. Termination. (a) This Agreement may be terminated with respect to the Securities in the sole discretion of the Representatives by notice to the Company and the Operating Partnership given prior to the Closing Date in the event that the Company or the Operating Partnership shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date:

(i) the Operating Partnership or any of the Subsidiaries shall have, in the sole judgment of the Representatives, sustained any material loss or interference with their respective businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any labor dispute or any legal or governmental proceeding or there shall have been any material adverse change, or any development involving a prospective material adverse change (including without limitation a change in management or control of the Company, which includes the termination of the employment of Mitchell E. Hersh), in the condition (financial or otherwise), business, prospects, net worth or results of operations of the Company, the Operating Partnership and the Subsidiaries, except in each case as described in or contemplated by the Prospectus (exclusive of any amendment or supplement thereto);

(ii) trading in the Company's Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or minimum or maximum prices shall have been established on such exchange;

(iii) there shall have been any downgrading in the rating of any debt securities or preferred stock of the Operating Partnership or the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of the Operating Partnership or the Company (other

than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating);

(iv) a banking moratorium shall have been declared by New York or United States authorities; or

(v) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or (C) any other calamity or crisis or material adverse change in general economic, political or financial conditions having an effect on the U.S. financial markets that, in the sole judgment of the Representatives, makes it impractical or inadvisable to proceed with the public offering or the delivery of the Securities as contemplated by the Registration Statement, as amended at the date of this Agreement as specified in Schedule 1 hereto.

(b) Termination of this Agreement pursuant to this Section 10 shall be without liability of any party to any other party except as provided in Section 9 hereof.

11. Information Supplied by Underwriters. The statements set forth in Schedule 1 hereto constitute the only information furnished by any Underwriter through the Representatives to the Operating Partnership for the purposes of Sections 2(b) and 7(b) hereof. The Underwriters confirm that such statements are correct.

12. Notices. All communications hereunder shall be in writing and, if sent to any of the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission and confirmed in writing to Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York, 10013, Attention: Syndicate Department; and if sent to the Operating Partnership or the Company, shall be delivered or sent by mail, telex or facsimile transmission and confirmed in writing to the Operating Partnership at 11 Commerce Drive, Cranford, New Jersey, 07016, Attention: Mitchell E. Hersh.

13. Successors. This Agreement shall inure to the benefit of and shall be binding upon the several Underwriters, the Operating Partnership, the Company and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person except that (i) the indemnities of the Operating Partnership and the Company contained in Section 7 of this Agreement shall also be for the benefit of any person or persons who control any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Underwriters contained in Section 7 of this Agreement shall also be for the benefit of the directors of the Company, the officers of the Company who have signed the Registration Statement as amended at the date of this Agreement as specified in Schedule 1 hereto and any person

or persons who control the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of Securities from any Underwriter shall be deemed a successor because of such purchase.

14. Applicable Law. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS.

15. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

If the foregoing correctly sets forth our understanding, please indicate your acceptance thereof in the space provided below for that purpose, whereupon this letter shall constitute an agreement binding the Company, the Operating Partnership and each of the several Underwriters.

Very truly yours,
