(6) director’s fees and any employment, consulting, service or termination agreement, or reasonable and customary indemnification arrangements, entered into by the Operating Partnership or any of its Restricted Subsidiaries with officers, directors and employees of the Company, the Operating Partnership or its Restricted Subsidiaries that are Affiliates of the Operating Partnership or its Restricted Subsidiaries and the payment of compensation to such officers, directors and employees (including amounts paid or securities issued pursuant to employee benefit plans, employee stock option or similar plans), or loans and advances to any officer, director or employee, so long as such agreement has been approved by the Board of Directors;

(7) commission, payroll, travel and similar advances or loans (including payment or cancellation thereof) to officers and employees of the Company, the Operating Partnership or any of its Restricted Subsidiaries;

(9) any transaction with any Person who is not an Affiliate immediately before the consummation of such transaction that becomes an Affiliate as a result of such transaction;

(10) any transaction with a joint venture, partnership, limited liability company or other entity that would constitute an Affiliate transaction solely because the Operating Partnership or a Restricted Subsidiary owns an equity interest in such joint venture, partnership, limited liability company or other entity; or

(11) any merger, consolidation or reorganization of the Operating Partnership or a Restricted Subsidiary (otherwise permitted by the Indenture) with or into a Restricted Subsidiary solely for the purpose of changing the domicile of the Operating Partnership or a Restricted Subsidiary.

Section 4.09. Limitation on Asset Sales. The Operating Partnership shall not, and shall not permit any of its Restricted Subsidiaries to, consummate any Asset Sale, unless:

(1) the consideration received by the Operating Partnership or such Restricted Subsidiary is at least equal to the Fair Market Value of the assets sold or disposed of, and

(2) at least 75% of the consideration received consists of cash or Temporary Cash Investments or a combination of both; provided that, with respect to the sale of one or more real estate properties, up to 75% of the consideration may consist of Indebtedness of the purchaser of such real estate properties so long as such Indebtedness is secured by a first priority Lien on the real estate property or properties sold; and provided, further that, for purposes of this clause (2) the amount of the following will be deemed to be cash:

(a) any liabilities, as shown on the Operating Partnership’s or such Restricted Subsidiary’s most recent balance sheet, of the Operating Partnership or any such Restricted Subsidiary’s (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets but, except in the case of an Asset Sale to a Restricted Subsidiary, only to the extent of the reduction in the amount of such liabilities on the Operating Partnership’s consolidated balance sheet;

(b) any securities, evidences of Indebtedness or other obligations received by the Operating Partnership, any Subsidiary Guarantor or any such Restricted Subsidiary from such transferee that are immediately converted by the Operating Partnership, the Subsidiary Guarantor or such Restricted Subsidiary into cash (or as to which the Operating Partnership, any Subsidiary Guarantor or such Restricted Subsidiary has received at or prior to the consummation of the Asset Sale a commitment (which may be subject to customary conditions) from a nationally recognized investment, merchant or commercial bank to convert into cash within one-hundred eighty (180) days of the consummation of such Asset Sale and which are thereafter actually converted into cash within such 180-day period); and

(c) any Designated Non-cash Consideration received by the Operating Partnership or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed $25 million, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

In the event that the Net Cash Proceeds received by the Operating Partnership or such Restricted Subsidiary from one or more Asset Sales occurring on or after the Issue Date in any period of twelve consecutive months (the “Asset Period”) exceeds 1% of Total Assets (determined as of the date closest to the commencement of the Asset Period for which a consolidated balance sheet of the Operating Partnership and its Restricted Subsidiaries is available), then within twelve (12) months after the date Net Cash Proceeds exceed 1% of Total Assets as described above, the Operating Partnership shall or shall cause the excess amount to be applied to:

(A) permanently reduce Secured Indebtedness of the Operating Partnership or any Restricted Subsidiary or Indebtedness of any other Restricted Subsidiary that is not a Guarantor, in each case owing to a Person other than the Company, the Operating Partnership or any of its Restricted Subsidiaries;

(B) make a capital expenditure or invest in property or assets (other than current assets) of a nature or type or that are used in a business (or in a Restricted Subsidiary, or a Person that becomes a Restricted Subsidiary upon such an Investment, having property and assets of a nature or type, or engaged in a business) similar or related to the nature or type of the property and assets of, or the business of, the Operating Partnership or any of its Restricted Subsidiaries existing on the date of such capital expenditure or investment (or enter into a definitive agreement committing to make such capital expenditure or so invest within 12 months after the date of such agreement);

(C) prepay, repay, redeem or purchase any notes or other pari passu Indebtedness of the Operating Partnership or of any Subsidiary Guarantor or any Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor, in each case owing to a Person other than the Company, the Operating Partnership or any Subsidiary of the Operating Partnership or any other Affiliate of the Operating Partnership; provided, that if the Operating Partnership or a Subsidiary Guarantor shall so prepay, repay, redeem or purchase any such notes or pari passu Indebtedness, the Operating Partnership shall equally and ratably reduce obligations under the notes as provided under Section 3.01, through open-market purchases (provided that such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for an Offer to Purchase pursuant to this Section 4.09) to all holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest;

(D) fund all or a portion of an optional redemption of the notes pursuant to Section 3.01; or

(E) undertake any combination of the foregoing.

Pending the application of any such Net Cash Proceeds as described above, the Operating Partnership may invest such Net Cash Proceeds in any manner that is not prohibited by the Indenture. The amount of such excess Net Cash Proceeds required to be applied (or to be committed to be applied) during such 12-month period as set forth in the preceding sentence and not applied as so required by the end of such period shall constitute “Excess Proceeds”. If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds not previously subject to an Offer to Purchase pursuant to this Section 4.09 totals more than $25 million, the Operating Partnership must commence, not later than

the fifteenth Business Day of such month, and consummate an Offer to Purchase from the Holders of the Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, on a pro rata basis, an aggregate principal amount of Notes and such other Indebtedness equal to the Excess Proceeds on such date, at a purchase price equal to 100% of the principal amount of the Notes and such other Indebtedness plus, in each case, accrued interest and Additional Interest (if any) to the Payment Date.

If the aggregate principal amount of the Notes and the other Indebtedness that is pari passu with the Notes tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, then the Notes and the other Indebtedness that is pari passu with the Notes will be purchased on a pro rata basis based on the principal amount of the Notes and the other Indebtedness that is pari passu with the Notes tendered. Upon completion of each Offer to Purchase, any remaining Excess Proceeds subject to such Offer to Purchase will no longer be deemed to be Excess Proceeds.

Section 4.10. Repurchase of Notes Upon a Change of Control. (a) Unless the Operating Partnership has previously or concurrently delivered a redemption notice with respect to all existing Notes pursuant to Section 3.01 and all conditions precedent applicable to such redemption notice have been satisfied, the Operating Partnership must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price equal to 101% of the principal amount of the Notes, plus accrued interest and Additional Interest (if any) to the Payment Date.

(b) The Operating Partnership will not be required to make an Offer to Purchase upon a Change of Control if a third party makes the Offer to Purchase in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to an Offer to Purchase made by the Operating Partnership and purchases all Notes validly tendered and not withdrawn under such Offer to Purchase. Notwithstanding anything to the contrary in the Indenture, an Offer to Purchase may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Offer to Purchase.

(c) The Operating Partnership will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, the Operating Partnership will comply with the applicable securities laws or regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the Indenture by virtue of such compliance.

Section 4.11. SEC Reports and Reports to Holders. (a) Whether or not the Operating Partnership or the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Operating Partnership and the Company must provide the Trustee and Holders within fifteen (15) Business Days after filing, or in the event no such filing is required, within fifteen (15) Business Days after the end of the time periods specified in those sections with:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Operating Partnership or the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual financial statements only, a report thereon by the Operating Partnership’s and the Company’s certified independent accountants, and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Operating Partnership and the Company were required to file such reports,

provided that the foregoing delivery requirements shall be deemed satisfied if the foregoing materials are available on the SEC’s ▇▇▇▇▇ system or any successor system or on the Operating Partnership’s or the Company’s website within the applicable time period.

(b) In addition, whether or not required by the Commission, the Company will, if the SEC will accept the filing, file a copy of all of the information and reports referred to in clauses (1) and (2) of Section 4.11(a) with the Commission for public availability within the time periods specified in the Commission’s rules and regulations. In addition, the Operating Partnership and the Company will make the information and reports available to securities analysts and prospective investors upon request. If the Operating Partnership had any Unrestricted Subsidiaries during the relevant period, the Operating Partnership will also provide to the Trustee and the Holders information sufficient to ascertain the financial condition and results of operations of the Operating Partnership and its Restricted Subsidiaries, excluding in all respects the Unrestricted Subsidiaries.

(c) Notwithstanding anything herein to the contrary, the Operating Partnership and the Company will not be deemed to have failed to comply with any provision of the reporting covenant in Section 4.11(b) for purposes of clause (4) of Section 6.02 as a result of the late filing or provision of any required information or report until 90 days after the date any such information or report was due.

(d) All obligors on the Notes will comply with Section 314(a) of the Trust Indenture Act.

(e) Delivery of these reports and information to the Trustee is for informational purposes only and the Trustee’s receipt of them will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Operating Partnership’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.12. Suspension of Covenants. (a) For so long as (i) the Notes are rated Investment Grade by each of S&P and ▇▇▇▇▇’▇ (or, if either (or both) of S&P and ▇▇▇▇▇’▇ have been substituted in accordance with the definition of “Rating Agencies,” by each of the then applicable Rating Agencies) and (ii) no Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), and conditioned upon the Operating Partnership promptly providing the Trustee an Officers’ Certificate and an Opinion of Counsel as to the existence of a Covenant Suspension Event which identifies the date of such Covenant Suspension Event, the Operating Partnership and its Restricted Subsidiaries will not be subject to Section 4.02, Section 4.04, Section 4.05, Section 4.06, Section 4.07, Section 4.08, Section 4.09 and clause (3) of Section 5.01 (the “Suspended Covenants”).

(b) Additionally, during such time as the above referenced covenants are suspended, the Operating Partnership will not be permitted to designate any Restricted Subsidiary as an Unrestricted Subsidiary unless the Operating Partnership would have been permitted to designate such Subsidiary as an Unrestricted Subsidiary if the covenants had been in effect for such period.

(c) If at any time the Notes’ credit rating is downgraded from an Investment Grade rating or if a Default or Event of Default occurs and is continuing, then the Suspended Covenants will thereafter be reinstated as if such covenants had never been suspended (the “Reinstatement Date”) and will be applicable pursuant to the terms of the Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the Indenture), unless and until the Notes subsequently attain an Investment Grade rating and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade rating and no Default or Event of Default is in existence); provided that no Default, Event of Default or breach of any kind shall be deemed to exist under the Indenture, the Notes or the Guarantees with respect to the Suspended Covenants based on, and none of the Operating Partnership or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising prior to the

Reinstatement Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reinstatement Date, if any, is referred to as the “Suspension Period.”

(d) The Operating Partnership shall deliver an Officers’ Certificate to the trustee specifying (i) if a Covenant Suspension Event has occurred and (ii) if a Reinstatement Date has occurred; provided that in no case shall such Reinstatement Date be conditioned upon the receipt of such Officers’ Certificate.

(e) Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments under Section 4.05 will be made as though the covenants described under Section 4.05 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under clause (C) of Section 4.05(a), to the extent set forth in such covenant.

(f) The Trustee shall not have any duty to monitor whether or not a Covenant Suspension Event or Reinstatement Date has occurred or ended, nor any duty to notify the noteholders of any of the foregoing.

Section 4.13. Reports to Trustee. The Operating Partnership and the Company will notify the Trustee if and when any Notes are listed on any national securities exchange and of any delisting.

(4) the Operating Partnership delivers to the Trustee an Officers’ Certificate (attaching the arithmetic computations to demonstrate compliance with clause (3), if applicable) and an Opinion of Counsel, in each case stating that such consolidation, merger or transfer and such supplemental indenture complies with this provision and that all conditions precedent provided for herein relating to such transaction have been complied with; provided that clause (3) above does not apply if, in the good faith determination of the Board of Directors, whose determination shall be evidenced by a Board Resolution, the principal purpose of such transaction is to change the state of domicile of the Operating Partnership, so long as any such transaction shall not have as one of its purposes the evasion of the foregoing limitations.

Upon any consolidation or merger or any transfer of all or substantially all of the Operating Partnership’s assets, in accordance with the foregoing, the successor Person formed by such consolidation or into which the Operating Partnership is merged or to which such transfer is made, shall succeed to, be substituted for, and may exercise every one of the Operating Partnership’s rights and powers under the Indenture with the same effect as if such successor Person had been named therein as the Operating Partnership and, except in the case of the lease or a sale or other transfer of less than all assets, the Operating Partnership shall be released from the obligations under the Notes.

Section 5.03. Consolidation, Merger and Sale of Assets by a Guarantor.

(5) there occurs with respect to any issue or issues of Indebtedness of the Operating Partnership or the Company or any Significant Subsidiary having an outstanding principal amount of $35 million or more in the aggregate for all such issues of all such Persons, whether such Indebtedness now exists or shall hereafter be created:

(i) an event of default that has caused the holder thereof to declare such Indebtedness to be due and payable prior to its Stated Maturity and such Indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days of such acceleration; and/or

(ii) the failure to make a principal payment at the final (but not any interim) fixed maturity and such defaulted payment shall not have been made, waived or extended within 30 days of such payment default;

Section 6.03. Acceleration. (a) If an Event of Default, other than a bankruptcy default with respect to the Operating Partnership or the Company, occurs and is continuing under the Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Operating Partnership and the Company (and to the Trustee if the notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal, premium, if any, and accrued interest will become immediately due and payable. In the event of a declaration of acceleration because an Event of Default set forth in clause (5) above has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the Event of Default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by the Operating Partnership, the Company or the relevant Significant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto. If a bankruptcy default occurs with respect to the Operating Partnership or the Company, the principal of, premium, if any, and accrued interest on the Notes then outstanding shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b) The Holders of at least a majority in principal amount of the outstanding Notes by written notice to the Operating Partnership, the Company and to the Trustee may waive all past Defaults and rescind and annul a declaration of acceleration and its consequences if:

(1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration, have been cured or waived, and

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

Section 6.04. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of and interest on the Notes or to enforce the performance of any provision of the Notes or the Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding.

Section 6.05. Waiver of Past Defaults. Except as otherwise provided in Sections Section 6.036.03, 6.08 and 9.04, the Holders of not less than a majority in principal amount of the outstanding Notes may, by notice to the Trustee, waive an existing Default and its consequences. Upon such waiver, the Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.06. Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes.

Section 6.07. Limitation on Suits. A Holder may not institute any proceeding, judicial or otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy under the Indenture or the Notes, unless:

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) during such 60-day period, the Holders of at least a majority in aggregate principal amount of the outstanding Notes have not given the Trustee a direction that is inconsistent with such written request.

Section 6.08. Rights of Holders to Receive Payment. Notwithstanding anything to the contrary, the right of a Holder of a Note to receive payment of principal of, premium, if any, or interest on its Note on or after the Stated

Maturities thereof, or to bring suit for the enforcement of any such payment on or after such respective dates, may not be impaired or affected without the consent of that Holder.

Section 6.09. Collection Suit by Trustee. If an Event of Default in payment of principal or interest specified in clause (1) or (2) of Section 6.02 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and overdue installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

Section 6.10. Trustee May File Proofs of Claim. The Trustee may file proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders allowed in any judicial proceedings relating to the Operating Partnership or any Guarantor or their respective creditors or property, and is entitled and empowered to collect, receive and distribute any money, securities or other property payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee hereunder. Nothing in the Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.11. Priorities. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

First: to the Trustee for all amounts due hereunder;

Second: to Holders for amounts then due and unpaid for principal of and interest on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest; and

Third: to the Operating Partnership or as a court of competent jurisdiction may direct.

The Trustee, upon written notice to the Operating Partnership, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.11.

Section 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Operating Partnership, any Guarantors, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Operating Partnership, any Guarantors, the Trustee and the Holders will continue as though no such proceeding had been instituted.

Section 6.13. Undertaking for Costs. In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the outstanding Notes.

Section 6.14. Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under the Indenture is intended to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other right or remedy.

Section 6.15. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.16. Waiver of Stay, Extension or Usury Laws. The Operating Partnership and each Guarantor covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Operating Partnership or the Guarantor from paying all or any portion of the principal of, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the Indenture. The Operating Partnership and each Guarantor hereby expressly waives, to the extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

THE TRUSTEE

Section 7.01. General. The first paragraph of Section 601 of the Base Indenture is hereby amended and restated in full, with respect to the Notes, to read as follows:

“The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act; provided, that (i) notwithstanding Section 315(a)(2) of the Trust Indenture Act, the Trustee need not confirm or investigate the accuracy of any mathematical calculations or other facts, statements, opinions or conclusions stated in the certificates or opinions referred to therein, and (ii) except during the continuance of an Event of Default, the Trustee need perform only those duties that are specifically set forth in the Indenture and no others, and no implied covenants or obligations will be read into the Indenture against the Trustee. In case an Event of Default has occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.”

ARTICLE 8

DEFEASANCE AND DISCHARGE

Section 8.01. Applicability of Article Four of the Base Indenture. Article Four of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article 8 shall, with respect to the Notes, supersede in its entirety Article Four of the Base Indenture and all references in the Base Indenture to Article Four thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 8 and the provisions set forth in this Article 8.

Section 8.02. Discharge of Operating Partnership’s Obligations. (a) Subject to paragraph (b), the Operating Partnership’s obligations under the Notes and the Indenture, and each Guarantor’s obligations under its Note Guarantee, will terminate if:

(1) all Notes previously authenticated and delivered (other than (i) destroyed, lost or stolen Notes that have been replaced or (ii) Notes that are paid pursuant to Section 1001 of the Base Indenture or (iii) Notes for whose payment money or U.S. Government Obligations have been held in trust and then repaid to the Operating Partnership pursuant to Section 8.06) have been delivered to the Trustee for cancellation and the Operating Partnership has paid all sums payable by it hereunder; or

(2) (A) the Notes mature within sixty days, or all of them are to be called for redemption within sixty days under arrangements satisfactory to the Trustee for giving the notice of redemption,

(B) the Operating Partnership irrevocably deposits in trust with the Trustee, as trust funds solely for the benefit of the Holders, money or U.S. Government Obligations or a combination thereof sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certificate delivered to the Trustee, without consideration of any reinvestment, to pay principal of and interest on the Notes to maturity or redemption, as the case may be, and to pay all other sums payable by it hereunder,

(D) the deposit will not result in a breach or violation of, or constitute a default under, the Indenture or any other agreement or instrument to which the Operating Partnership is a party or by which it is bound, and

(E) the Operating Partnership delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, in each case stating that all conditions precedent provided for herein relating to the satisfaction and discharge of the Indenture have been complied with.

(b) After satisfying the conditions in clause (1), only the Operating Partnership’s obligations under Section 606 of the Base Indenture will survive. After satisfying the conditions in clause (2), only the Operating Partnership’s obligations in Article 2 and Sections 8.06 and 8.07 and Sections 606, 608, 1001 and 1002 of the Base Indenture will survive. In either case, the Trustee upon request will acknowledge in writing the discharge of the Operating Partnership’s obligations under the Notes and the Indenture (and each Guarantor’s obligations under its Note Guarantee) other than the surviving obligations.

Section 8.03. Legal Defeasance. After the 123rd day following the deposit referred to in clause (1), the Operating Partnership will be deemed to have paid and will be discharged from its obligations in respect of the Notes and the Indenture, other than its obligations in Article 2 and Sections 8.06 and 8.07 and Sections 606, 608, 1001 and 1002 of the Base Indenture and each Guarantor’s obligations under its Note Guarantee will terminate, provided the following conditions have been satisfied:

(1) The Operating Partnership has irrevocably deposited in trust with the Trustee, as trust funds solely for the benefit of the Holders, money or U.S. Government Obligations or a combination thereof sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certificate thereof delivered to the Trustee, without consideration of any reinvestment, to pay principal of and accrued interest on the Notes on the Stated Maturity of such payments in accordance with the terms of the Indenture and the Notes.

(2) Immediately after giving effect to the deposit referred to in clause (i) above on a pro forma basis, no Default or Event of Default shall have occurred and be continuing on the date of such deposit or occur at any time during the 123-day period following the deposit.

(3) The deposit will not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which the Operating Partnership or any of its Restricted Subsidiaries is a party or by which the Operating Partnership or any of its Restricted Subsidiaries is bound.

(4) The Operating Partnership has delivered to the Trustee

(A) an Opinion of Counsel to the effect that beneficial owners will not recognize income, gain or loss for federal income tax purposes as a result of the Operating Partnership’s exercise of its option pursuant to this Section 8.03 and will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case if such deposit, defeasance and discharge had not occurred, which Opinion of Counsel must be based upon (and accompanied by a copy of) a ruling of the Internal Revenue Service to the same effect unless there has been a change in applicable federal income tax law after the Issue Date such that a ruling is no longer required, and

(B) an Opinion of Counsel to the effect that (i) the creation of the defeasance trust does not violate the Investment Operating Partnership Act of 1940, (ii) the Holders have a valid first priority Note interest in the trust funds (subject to customary exceptions), and (iii) after the passage of 123 days following the deposit, the trust funds will not be subject to the effect of ▇▇▇▇▇▇▇ ▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law.

(5) If at such time the Notes are listed on a national securities exchange, the Operating Partnership has delivered to the Trustee an Opinion of Counsel to the effect that such deposit, defeasance and discharge will not cause the Notes to be delisted.

(6) The Operating Partnership has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, in each case stating that all conditions precedent provided for herein relating to the defeasance have been complied with.

Prior to the end of the 123-day period, none of the Operating Partnership’s obligations under the Indenture (nor any Guarantor’s obligations under its Note Guarantee) will be discharged. Thereafter, the Trustee upon request will acknowledge in writing the discharge of the Operating Partnership’s obligations under the Notes and the Indenture (and each Guarantor’s obligations under its Note Guarantee) except for the surviving obligations specified above.

Section 8.04. Covenant Defeasance. After the 123rd day following the deposit referred to in clause (1), the Operating Partnership’s obligations set forth in Section 4.02 through Section 4.11, inclusive, and clauses (3) and (4) of Section 5.01 will terminate and clause (3) under Section 6.01 with respect to clauses (3) and (4) of Section 5.02, clause (4) under Section 6.02 with respect to Section 4.02 through Section 4.11, inclusive, and clauses (5) and (6) under Section 6.01 will no longer constitute Events of Default, provided the following conditions have been satisfied:

(1) The Operating Partnership has complied with clauses (1), (2), (3), 4(B), (5) and (6) of Section 8.03; and

(2) the Operating Partnership has delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case.

Except as specifically stated above, none of the Operating Partnership’s obligations under the Indenture will be discharged.

Section 8.05. Application of Trust Money. Subject to Section 8.06, the Trustee will hold in trust the money or U.S. Government Obligations deposited with it pursuant to Section 8.02, 8.03 or 8.04, and apply the deposited money and the proceeds from deposited U.S. Government Obligations to the payment of principal of and interest on the Notes in accordance with the Notes and the Indenture. Such money and U.S. Government Obligations need not be segregated from other funds except to the extent required by law.

Section 8.06. Repayment to Operating Partnership. Subject to Sections 8.02, 8.03 and 8.04 and Section 608 of the Base Indenture the Trustee will promptly pay to the Operating Partnership upon request any excess money held by the Trustee at any time and thereupon be relieved from all liability with respect to such money. The Trustee will pay to the Operating Partnership upon request any money held for payment with respect to the Notes that remains unclaimed for two years, provided that before making such payment the Trustee may at the expense of the Operating Partnership publish once in a newspaper of general circulation in New York City, or send to each Holder entitled to such money, notice that the money remains unclaimed and that after a date specified in the notice (at least 30 days after the date of the publication or notice) any remaining unclaimed balance of money will be repaid to the Operating Partnership. After payment to the Operating Partnership, Holders entitled to such money must look solely to the Operating Partnership for payment, unless applicable law designates another Person, and all liability of the Trustee with respect to such money will cease.

Section 8.07. Reinstatement. If and for so long as the Trustee is unable to apply any money or U.S. Government Obligations held in trust pursuant to Section 8.02, 8.03 or 8.04 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Operating Partnership’s and the Guarantor’s obligations under the Indenture and the Notes will be reinstated as though no such deposit in trust had been made. If the Operating Partnership or a Guarantor makes any payment of principal of or interest on any Notes because of the reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held in trust.

ARTICLE 9

AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 9.01. Applicability of Article Nine of the Base Indenture. Article Nine of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article 9 shall, with respect to the Notes, supersede in its entirety Article Nine of the Base Indenture and all references in the Base Indenture to Article Nine thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 9 and the provisions set forth in this Article 9.

Section 9.02. Amendments Without Consent of Holders. The Operating Partnership, the Company and the Trustee may amend or supplement the Indenture, the Notes and the Note Guarantees without notice to or the consent of any Noteholder

(1) to cure any ambiguity, defect, omission or inconsistency in the Indenture or the Notes;

(2) to comply with Article 5 herein;

(3) to comply with any requirements of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act;

(4) to evidence and provide for the acceptance of an appointment hereunder by a successor Trustee;

(5) to provide for uncertificated Notes in addition to or in place of certificated Notes, provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code;

(6) to provide for any Guarantee of the Notes, to secure the Notes or to confirm and evidence the release, termination or discharge of any Guarantee of or Lien securing the Notes when such release, termination or discharge is permitted by the Indenture;

(7) to provide for the issuance of additional Notes in accordance with the terms of the Indenture;

(8) to conform any provision of the Indenture to the “Description of the Notes” section contained in the Preliminary Prospectus Supplement relating to the Notes dated June 2, 2015 as superseded, to the extent inconsistent, by the Pricing Term Sheet dated June 4, 2015; or

(9) to make any other change that does not materially and adversely affect the rights of any Holder.

Section 9.03. Amendments With Consent of Holders. (a) Except as otherwise provided in Sections 6.03, 6.05, 6.08 or Section 9.03(b), the Operating Partnership, the Company and the Trustee may amend the Indenture and the Notes with the written consent of the Holders of at least a majority in principal amount of the outstanding Notes, and the Holders of at least a majority in principal amount of the outstanding Notes by written notice to the Trustee may waive future compliance by the Operating Partnership with any provision of the Indenture or the Notes.

(b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder affected, an amendment or waiver may not

(1) change the Stated Maturity of the principal of, or any installment of interest on, any Note;

(2) reduce the principal amount of, or premium, if any, or interest on, any Note;

(3) change the place of payment of principal of, or premium, if any, or interest on, any Note;

(4) impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity (or, in the case of a redemption, on or after the Redemption Date) of any Note;

(5) reduce the above-stated percentages of outstanding Notes the consent of whose Holders is necessary to modify or amend the Indenture;

(6) waive a default in the payment of principal of, premium, if any, or interest on the Notes;

(7) voluntarily release a Guarantor of the Notes other than in accordance with the Indenture;

(8) after the time an Offer to Purchase is required to have been made under Section 4.09 or Section 4.10 reduce the purchase amount or price or extend the latest expiration date or purchase date thereunder; or

(9) reduce the percentage or aggregate principal amount of outstanding Notes the consent of whose Holders is necessary for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults.

(c) It is not necessary for Noteholders to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

(d) An amendment, supplement or waiver under this Section 9.03 will become effective on receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes. After an amendment, supplement or waiver under this Section 9.03 becomes effective, the Operating Partnership will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. The Operating Partnership will send supplemental indentures to Holders upon request. Any failure of the Operating Partnership to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 9.04. Effect of Consent. (a) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

(b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed terms. The Trustee may also place an appropriate notation on any Note thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

Section 9.05. Trustee’s Rights and Obligations. The Trustee is entitled to receive, and will be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article 9 is authorized or permitted by the Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights, duties or immunities under the Indenture.

Section 9.06. Conformity With Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

Section 9.07. Payments for Consents. Neither the Operating Partnership nor any of its Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.

ARTICLE 10

GUARANTEES

Section 10.01. The Guarantees. The provisions of Article Sixteen of the Base Indenture shall apply to the Notes. The Guarantors hereto hereby agree to perform all of the obligations and agreements of a “Guarantor” as defined in the Base Indenture.

Section 10.02. Limitation on Amount of Guarantee. Notwithstanding anything to the contrary in this Article 10 and Article Sixteen of the Base Indenture, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Note Guarantee are limited to the maximum amount that would not render the Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 10.03. Execution and Delivery of Guarantee. The execution by each Guarantor of the Indenture (or a supplemental indenture substantially in the form of Exhibit B) evidences the Note Guarantee of such Guarantor, whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in the Indenture on behalf of each Guarantor.

Section 10.04. Release of Guarantee. (a) The Note Guarantee of a Guarantor other than the Company will automatically terminate upon:

(1) a sale or other disposition (including by way of consolidation or merger) of the Guarantor, or the Capital Stock of the Guarantor such that the Guarantor is no longer a Subsidiary, or the sale or disposition of all or substantially all the assets of the Guarantor (other than to the Operating Partnership or a Restricted Subsidiary) otherwise permitted or not prohibited by the Indenture,

(2) the release of the Guarantees of all other Indebtedness by such Guarantor, unless at the time of such release a Default or Event of Default shall have occurred and be continuing under the Indenture;

(3) the designation in accordance with the Indenture of the Guarantor as an Unrestricted Subsidiary, or

(4) defeasance or discharge of the Notes, as provided in Section 8.01, Section 8.03 or Section 8.04.

(b) The Note Guarantee of the Company will automatically terminate upon:

(1) the release of the Guarantees of all other Indebtedness by the Company, unless at the time of such release a Default or Event of Default shall have occurred and be continuing under the Indenture; or

(2) defeasance or discharge of the Notes, as provided in Section 8.02, Section 8.03 or Section 8.04.

(c) In addition, if on any date following the Issue Date, the Notes are rated Investment Grade by both Rating Agencies, and in connection therewith each Rating Agency received written information from the Operating Partnership stating that the release of all of the Guarantees will occur upon an Investment Grade rating, and no Default or Event of Default shall have occurred and be continuing under the Indenture on the date of such release, then, beginning on that date, the Guarantors will be automatically released from their obligations under the Guarantees; provided that as soon as possible following a Reinstatement Date, the Company and each of the Operating Partnership’s Restricted Subsidiaries who would have been required to Guarantee the Notes but for the foregoing, shall execute and deliver a supplemental indenture to the Indenture providing for the reinstatement of the Note Guarantee by the Company and a Subsidiary Guarantee by such Restricted Subsidiary.

(d) Upon delivery by the Operating Partnership to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under its Note Guarantee.

ARTICLE 11

Section 11.02. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof, or with a provision of the Base Indenture, or with a provision of the Trust Indenture Act, which is required to be included in this First Supplemental Indenture, or in the Base Indenture, respectively, by any of the provisions of the Trust Indenture Act, such required provision shall control to the extent it is applicable.

Section 11.05. Successors. All agreements of the Operating Partnership or any Guarantor in the Indenture and the Notes will bind its successors. All agreements of the Trustee in the Indenture will bind its successor.

Section 11.08. Table of Contents and Headings. The Table of Contents and headings of the Articles and Sections herein have been inserted for convenience of reference only, are not to be considered a part of the Indenture and in no way modify or restrict any of the terms and provisions of the Indenture.

Section 11.09. No Liability of Directors, Officers, Employees, Incorporators, Members and Stockholders. Section 118 of the Base Indenture is hereby amended and restated in full, with respect to the Notes, to read as follows:

The waiver and release are part of the consideration for issuance of the Notes.”

Section 11.10. Trustee Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except the Trustee’s certificate of authentication, shall be taken as the statements of the Operating Partnership, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this First Supplemental Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this First Supplemental Indenture, authenticate the Notes and perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Operating Partnership of the Notes or the proceeds thereof.
