WITNESSETH:

          WHEREAS, the Banks have agreed to make loans to Borrower in the aggregate principal amount not to exceed Five Hundred Fifty Million Dollars ($550,000,000) or, in the event that Borrower exercises its rights pursuant to Section 9.19 of the Credit Agreement, Seven Hundred Million Dollars ($700,000,000) (hereinafter collectively referred to as the “Loans”);

          WHEREAS, the Loans are and will be evidenced by (i) certain promissory notes of Borrower made to each of the Banks, (ii) certain promissory notes of Borrower made to each of the Designated Lenders, and (iii) certain promissory notes of one or more Qualified Borrowers made to each of the Banks, in each case in accordance with the terms of the Credit Agreement (collectively, the “Notes”);

          WHEREAS, the Credit Agreement and the Notes and any other documents executed in connection therewith are hereinafter collectively referred to as the “Loan Documents”;

          WHEREAS, capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Credit Agreement;

          WHEREAS, Guarantor is the sole general partner of Borrower;

          WHEREAS, Borrower has executed the Qualified Borrower Guaranty as contemplated by the Credit Agreement;

          WHEREAS, as a condition to the execution and delivery of the Loan Documents, the Banks have required that Guarantor execute and deliver this Guaranty of Payment; and

          NOW THEREFORE, in consideration of the premises and the benefits to be derived from the making of the Loans by the Banks to Borrower and Qualified Borrowers, and in order to induce the Administrative Agent, the Syndication Agent, the Documentation Agents, the Joint Lead Arrangers and Joint Bookmanagers, the Managing Agents and the Banks to enter into the Credit Agreement and the other Loan Documents, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby agrees as follows:

          1. Guarantor, on behalf of itself and its successors and assigns, hereby irrevocably, absolutely and unconditionally guarantees the full and punctual payment when due, whether at stated maturity or otherwise, of all Obligations of Borrower now or hereafter existing under the Notes and the Credit Agreement, including in the event that the Borrower exercises its rights under the Credit Agreement to increase the Facility Amount and including those Obligations of Borrower under the Qualified Borrower Guaranty, for principal and/or interest as well as any and all other amounts due thereunder, including, without limitation, all indemnity obligations of Borrower thereunder, and any and all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) incurred by the Administrative Agent and/or the Banks in enforcing their rights under this Guaranty (all of the foregoing obligations being the “Guaranteed Obligations”).

          2. It is agreed that the Guaranteed Obligations of Guarantor hereunder are primary and this Guaranty shall be enforceable against Guarantor and its successors and assigns without the necessity for any suit or proceeding of any kind or nature whatsoever brought by the Administrative Agent or any of the Banks against Borrower or its respective successors or assigns or any other party or against any security for the payment and performance of the Guaranteed Obligations and without the necessity of any notice of non-payment or non-observance or of any notice of acceptance of this Guaranty or of any notice or demand to which Guarantor might otherwise be entitled (including, without limitation, diligence, presentment, notice of maturity, extension of time, change in nature or form of the Guaranteed Obligations, acceptance of further security, release of further security, imposition or agreement arrived at as to the amount of or the terms of the Guaranteed Obligations, notice of adverse change in Borrower’s financial condition and any other fact which might materially increase the risk to Guarantor), all of which Guarantor hereby expressly waives; and Guarantor hereby expressly agrees that the validity of this Guaranty and the obligations of Guarantor hereunder shall in no way be terminated, affected, diminished, modified or impaired by reason of the assertion of or the failure to assert by the Administrative Agent or any of the Banks against Borrower or its respective successors or assigns, any of the rights or remedies reserved to the Administrative Agent or any of the Banks pursuant to the provisions of the Loan Documents. Guarantor agrees that any notice or directive given at any time to the Administrative Agent or any of the Banks which is inconsistent with the waiver in the immediately preceding sentence shall be void and may be ignored by the Administrative Agent and the Banks, and, in addition, may not be pleaded or introduced as evidence in any litigation relating to this Guaranty for the reason that such pleading or introduction would be at variance with the written terms of this

Guaranty, unless the Administrative Agent has specifically agreed otherwise in a writing, signed by a duly authorized officer. Guarantor specifically acknowledges and agrees that the foregoing waivers are of the essence of this transaction and that, but for this Guaranty and such waivers, the Administrative Agent and the Banks would not make the requested Loan to the Borrower.

          3. Guarantor waives, and covenants and agrees that it will not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any and all appraisal, valuation, stay, extension, marshaling-of-assets or redemption laws, or right of homestead or exemption, whether now or at any time hereafter in force, which may delay, prevent or otherwise affect the performance by Guarantor of its obligations under, or the enforcement by the Administrative Agent or any of the Banks of, this Guaranty. Guarantor further covenants and agrees not to set up or claim any defense, counterclaim, offset, setoff or other objection of any kind to any action, suit or proceeding in law, equity or otherwise, or to any demand or claim that may be instituted or made by the Administrative Agent or any of the Banks other than the defense of the actual timely payment and performance by Borrower of the Guaranteed Obligations hereunder; provided, however, that the foregoing shall not be deemed a waiver of Guarantor’s right to assert any compulsory counterclaim, if such counterclaim is compelled under local law or rule of procedure, nor shall the foregoing be deemed a waiver of Guarantor’s right to assert any claim which would constitute a defense, setoff, counterclaim or crossclaim of any nature whatsoever against Administrative Agent or any Bank in any separate action or proceeding. Guarantor represents, warrants and agrees that, as of the date hereof, its obligations under this Guaranty are not subject to any counterclaims, offsets or defenses against the Administrative Agent or any Bank of any kind.

          4. The provisions of this Guaranty are for the benefit of the Administrative Agent and the Banks and their successors and permitted assigns, and nothing herein contained shall impair as between Borrower and the Administrative Agent and the Banks the obligations of Borrower under the Loan Documents.

          5. This Guaranty shall be a continuing, unconditional and absolute guaranty and the liability of Guarantor hereunder shall in no way be terminated, affected, modified, impaired or diminished by reason of the happening, from time to time, of any of the following, all without notice or the further consent of Guarantor:

     (a) any assignment, amendment, modification or waiver of or change in any of the terms, covenants, conditions or provisions of any of the Guaranteed Obligations or the Loan Documents or the invalidity or unenforceability of any of the foregoing; or

     (b) any extension of time that may be granted by the Administrative Agent to Borrower, any guarantor, or their respective successors or assigns, heirs, executors, administrators or personal representatives; or

     (c) any action which the Administrative Agent may take or fail to take under

or in respect of any of the Loan Documents or by reason of any waiver of, or failure to enforce any of the rights, remedies, powers or privileges available to the Administrative Agent under this Guaranty or available to the Administrative Agent at law, equity or otherwise, or any action on the part of the Administrative Agent granting indulgence or extension in any form whatsoever; or

     (d) any sale, exchange, release, or other disposition of any property pledged, mortgaged or conveyed, or any property in which the Administrative Agent and/or the Banks have been granted a lien or security interest to secure any indebtedness of Borrower to the Administrative Agent and/or the Banks; or

     (e) any release of any person or entity who may be liable in any manner for the payment and collection of any amounts owed by Borrower to the Administrative Agent and/or the Banks; or

     (f) the application of any sums by whomsoever paid or however realized to any amounts owing by Borrower to the Administrative Agent and/or the Banks under the Loan Documents in such manner as the Administrative Agent shall determine in its sole discretion; or

     (g) Borrower’s or Guarantor’s voluntary or involuntary liquidation, dissolution, sale of all or substantially all of their respective assets and liabilities, appointment of a trustee, receiver, liquidator, sequestrator or conservator for all or any part of Borrower’s or Guarantor’s assets, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment, or the commencement of other similar proceedings affecting Borrower or Guarantor or any of the assets of any of them, including, without limitation, (i) the release or discharge of Borrower or any guarantor from the payment and performance of their respective obligations under any of the Loan Documents by operation of law, or (ii) the impairment, limitation or modification of the liability of Borrower or any guarantor in bankruptcy, or of any remedy for the enforcement of the Guaranteed Obligations under any of the Loan Documents, or any guarantor’s liability under this Guaranty, resulting from the operation of any present or future provisions of the Bankruptcy Code or other present or future federal, state or applicable statute or law or from the decision in any court; or

     (h) any improper disposition by Borrower of the proceeds of the Loans, it being acknowledged by Guarantor that the Administrative Agent or any Bank shall be entitled to honor any request made by Borrower for a disbursement of such proceeds and that neither the Administrative Agent nor any Bank shall have any obligation to see the proper disposition by Borrower of such proceeds.

          6. Guarantor agrees that if at any time all or any part of any payment at any time received by the Administrative Agent from Borrower or Guarantor under or with respect to

this Guaranty is or must be rescinded or returned by the Administrative Agent or any Bank for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of Borrower or Guarantor), then Guarantor’s obligations hereunder shall, to the extent of the payment rescinded or returned, be deemed to have continued in existence notwithstanding such previous receipt by such party, and Guarantor’s obligations hereunder shall continue to be effective or reinstated, as the case may be, as to such payment, as though such previous payment had never been made.

          7. Until this Guaranty is terminated pursuant to the terms hereof, Guarantor (i) shall have no right of subrogation against Borrower or any entity comprising same by reason of any payments or acts of performance by Guarantor in compliance with the obligations of Guarantor hereunder, (ii) waives any right to enforce any remedy which Guarantor now or hereafter shall have against Borrower or any entity comprising same by reason of any one or more payment or acts of performance in compliance with the obligations of Guarantor hereunder and (iii) from and after an Event of Default (as defined in the Credit Agreement), subordinates any liability or indebtedness of Borrower or any entity comprising same now or hereafter held by Guarantor or any affiliate of Guarantor to the obligations of Borrower under the Loan Documents. The foregoing, however, shall not be deemed in any way to limit any rights that Guarantor may have pursuant to the Agreement of Limited Partnership of Borrower or which it may have at law or in equity with respect to any other partners of Borrower.

          8. Guarantor represents and warrants to the Administrative Agent and the Banks with the knowledge that the Administrative Agent and the Banks are relying upon the same, as follows:

     (a) as of the date hereof, Guarantor is the sole general partner of Borrower;

     (b) based upon such relationships, Guarantor has determined that it is in its best interests to enter into this Guaranty;

     (c) this Guaranty is necessary and convenient to the conduct, promotion and attainment of Guarantor’s business, and is in furtherance of Guarantor’s business purposes;

     (d) the benefits to be derived by Guarantor from Borrower’s access to funds made possible by the Loan Documents are at least equal to the obligations undertaken pursuant to this Guaranty;

     (e) Guarantor is solvent and has full power and legal right to enter into this Guaranty and to perform its obligations under the term hereof and (i) Guarantor is organized and validly existing under the laws of the State of Maryland, (ii) Guarantor has complied with all provisions of applicable law in connection with all aspects of this Guaranty, and (iii) the person executing this Guaranty has all the requisite power and

authority to execute and deliver this Guaranty;

     (f) to the best of Guarantor’s knowledge, there is no action, suit, proceeding, or investigation pending or threatened against or affecting Guarantor at law, in equity, in admiralty or before any arbitrator or any governmental department, commission, board, bureau, agency or instrumentality (domestic or foreign) which is likely to materially and adversely impair the ability of Guarantor to perform its obligations under this Guaranty;

     (g) the execution and delivery of and the performance by Guarantor of its obligations under this Guaranty have been duly authorized by all necessary action on the part of Guarantor and do not (i) violate any provision of any law, rule, regulation (including, without limitation, Regulation U or X of the Board of Governors of the Federal Reserve System of the United States), order, writ, judgment, decree, determination or award presently in effect having applicability to Guarantor or the organizational documents of Guarantor the consequences of which violation is likely to materially and adversely impair the ability of Guarantor to perform its obligations under this Guaranty or (ii) violate or conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default under any indenture, agreement or other instrument to which Guarantor is a party, or by which Guarantor or any of its property is bound, the consequences of which violation, conflict, breach or default is likely to materially and adversely impair the ability of Guarantor to perform its obligations under this Guaranty;

     (h) this Guaranty has been duly executed by Guarantor and constitutes the legal, valid and binding obligation of Guarantor, enforceable against it in accordance with its terms except as enforceability may be limited by applicable insolvency, bankruptcy or other laws affecting creditors’ rights generally or general principles of equity, whether such enforceability is considered in a proceeding in equity or at law;

     (i) no authorization, consent, approval, license or formal exemption from, nor any filing, declaration or registration with, any Federal, state, local or foreign court, governmental agency or regulatory authority is required in connection with the making and performance by Guarantor of this Guaranty, except those which have already been obtained; and

     (j) Guarantor is not an “investment company” as that term is defined in, nor is it otherwise subject to regulation under, the Investment Company Act of 1940, as amended.

          9. Guarantor and Administrative Agent each acknowledge and agree that this Guaranty is a guarantee of payment and performance and not of collection and enforcement in respect of any obligations which may accrue to the Administrative Agent and/or the Banks from Borrower under the provisions of any Loan Document.

          10. Subject to the terms and conditions of the Credit Agreement, and in conjunction therewith, the Administrative Agent or any Bank may assign any or all of its rights under this Guaranty. In the event of any such assignment, the Administrative Agent shall give Guarantor prompt notice of same. If the Administrative Agent elects to sell all the Loans or participations in the Loans and the Loan Documents, including this Guaranty, the Administrative Agent or any Bank may forward to each purchaser and prospective purchaser all documents and information relating to this Guaranty or to Guarantor, whether furnished by Borrower or Guarantor or otherwise, subject to the terms and conditions of the Credit Agreement.

          11. Guarantor agrees, upon the written request of the Administrative Agent, to execute and deliver to the Administrative Agent, from time to time, any modification or amendment hereto or any additional instruments or documents reasonably considered necessary by the Administrative Agent or its counsel to cause this Guaranty to be, become or remain valid and effective in accordance with its terms, provided, that, any such modification, amendment, additional instrument or document shall not increase Guarantor’s obligations or diminish its rights hereunder and shall be reasonably satisfactory as to form to Guarantor and to Guarantor’s counsel.

          17.

          18. This Guaranty shall be binding upon Guarantor and its successors and assigns and shall inure to the benefit of the Administrative Agent and the Banks and their successors and permitted assigns.

          19. The failure of the Administrative Agent to enforce any right or remedy hereunder, or promptly to enforce any such right or remedy, shall not constitute a waiver thereof, nor give rise to any estoppel against the Administrative Agent, nor excuse Guarantor from its obligations hereunder. Any waiver of any such right or remedy to be enforceable against the Administrative Agent must be expressly set forth in a writing signed by the Administrative Agent.

          20. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

               (b) Any legal action or proceeding with respect to this Guaranty and any action for enforcement of any judgment in respect thereof may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York, and, by execution and delivery of this Guaranty, the Guarantor hereby accepts for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the

aforesaid courts and appellate courts from any thereof. The Guarantor irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Guarantor at its address for notices set forth herein. The Guarantor hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Guaranty brought in the courts referred to above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. Nothing herein shall affect the right of the Administrative Agent to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Guarantor in any other jurisdiction.

               (c) GUARANTOR HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY AND ALL CLAIMS OR CAUSES OF ACTION BASED UPON OR ARISING OUT OF THIS GUARANTY. IT IS HEREBY ACKNOWLEDGED BY GUARANTOR THAT THE WAIVER OF A JURY TRIAL IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT TO ACCEPT THIS GUARANTY AND THAT THE LOANS MADE BY THE BANKS ARE MADE IN RELIANCE UPON SUCH WAIVER. GUARANTOR FURTHER WARRANTS AND REPRESENTS THAT SUCH WAIVER HAS BEEN KNOWINGLY AND VOLUNTARILY MADE, FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, THIS GUARANTY MAY BE FILED BY THE ADMINISTRATIVE AGENT IN COURT AS A WRITTEN CONSENT TO A NON-JURY TRIAL.

               (d) Guarantor does hereby further covenant and agree to and with the Administrative Agent that Guarantor may be joined in any action against Borrower in connection with the Loan Documents and that recovery may be had against Guarantor in such action or in any independent action against Guarantor (with respect to the Guaranteed Obligations), without the Administrative Agent first pursuing or exhausting any remedy or claim against Borrower or its successors or assigns. Guarantor also agrees that, in an action brought with respect to the Guaranteed Obligations in any jurisdiction, it shall be conclusively bound by the judgment in any such action by the Administrative Agent (wherever brought) against Borrower or its successors or assigns, as if Guarantor were a party to such action, even though Guarantor was not joined as a party in such action.

               (e) Guarantor agrees to pay all reasonable expenses (including, without limitation, attorneys’ fees and disbursements) which may be incurred by the Administrative Agent or the Banks in connection with the enforcement of their rights under this Guaranty, whether or not suit is initiated.

          21. Notwithstanding anything to the contrary contained herein, this Guaranty shall terminate and be of no further force or effect upon the full performance and payment of the Guaranteed Obligations hereunder. Upon termination of this Guaranty in accordance with the

terms of this Guaranty, the Administrative Agent promptly shall deliver to Guarantor such documents as Guarantor or Guarantor’s counsel reasonably may request in order to evidence such termination.

          22. All of the Administrative Agent’s rights and remedies under each of the Loan Documents or under this Guaranty are intended to be distinct, separate and cumulative and no such right or remedy therein or herein mentioned is intended to be in exclusion of or a waiver of any other right or remedy available to the Administrative Agent.

          23. The Guarantor shall not use any assets of an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Internal Revenue Code (the “Code”) to repay or secure the Loan, the Note, the Obligations or this Guaranty. The Guarantor shall not assign, sell, pledge, encumber, transfer, hypothecate or otherwise dispose of any of its rights or interests (direct or indirect) in Borrower, or attempt to do any of the foregoing or suffer any of the foregoing, or permit any party with a direct or indirect interest or right in Borrower to do any of the foregoing, if such action would cause the Note, the Loan, the Obligations, this Guaranty, or any of the Loan Documents or the exercise of any of the Administrative Agent’s or Bank’s rights in connection therewith, to constitute a prohibited transaction under ERISA or the Code (unless the Guarantor furnishes to the Administrative Agent a legal opinion satisfactory to the Administrative Agent that the transaction is exempt from the prohibited transaction provisions of ERISA and the Code (and for this purpose, the Administrative Agent and the Banks, by accepting the benefits of this Guaranty, hereby agree to supply Guarantor all relevant non-confidential, factual information reasonably necessary to such legal opinion and reasonably requested by Guarantor) or would otherwise result in the Administrative Agent or any of the Banks being deemed in violation of Sections 404 or 406 of ERISA or Section 4975 of the Code or would otherwise result in the Administrative Agent or any of the Banks being a fiduciary or party in interest under ERISA or a “disqualified person” as defined in Section 4975(e)(2) of the Code with respect to an “employee benefit plan” within the meaning of Section 3(3) of ERISA or a “plan” within the meaning of Section 4975(e)(1) of the Code. The Guarantor shall indemnify and hold each of the Administrative Agent and the Banks free and harmless from and against all loss, costs (including attorneys’ fees and expenses), expenses, taxes and damages (including consequential damages) that each of the Administrative Agent and the Banks may suffer by reason of the investigation, defense and settlement of claims and in obtaining any prohibited transaction exemption under ERISA necessary in Administrative Agent’s reasonable judgment as a result of Guarantor’s action or inaction or by reason of a breach of the foregoing provisions by Guarantor.
