Upon the written request of any Stockholder, each other Stockholder shall vote, or act by written consent with respect to, all Voting Securities beneficially owned by him or it and otherwise take or cause to be taken all actions necessary to remove any Director designated by such Stockholder and to elect any replacement Director designated by such Stockholder.

SECTION 2.7. Preferred Provider Status.

ARTICLE III

TRANSFERS

SECTION 3.1. Rights and Obligations of Transferees. (a) No Transferee of any Stockholder, except a Permitted Transferee, shall be entitled to any rights under this Agreement. A Permitted Transferee shall become a party to this Agreement and shall be permitted to exercise all rights of the Transferring Stockholder under this Agreement with respect to Equity Securities Transferred.

(b) Notwithstanding anything to the contrary in this Agreement, no Transferee which is not a Permitted Transferee shall become a party to this Agreement or otherwise be bound by any of the terms and conditions of this Agreement.

SECTION 3.2. Right of First Offer by Stockholders. (a) If a Stockholder (for purposes of this Section 3.2, a “Selling Stockholder”) proposes to Transfer (unless the proposed Transfer is a Permitted Transfer, in which case the following provisions need not be complied with) all or any portion of its Equity Securities (the amount of Equity Securities proposed to be Transferred by the Selling Stockholder, the “Subject Securities”), such that the consummation of the proposed sale of the Subject Securities would result in a Controlled Company Event, the Selling Stockholder shall deliver a written notice of its intention to sell (a “Sale Notice”) to the other Stockholders that are not Affiliates of the Selling Stockholder (collectively, the “Offeree Stockholders”) setting forth the number of Subject Securities proposed to be Transferred, the terms and conditions pursuant to which the Selling Stockholder is offering to sell such Subject Securities and an irrevocable offer to sell the Subject Securities to the Offeree Stockholders in accordance the terms of this Section 3.2.

(b) Upon receipt of a Sale Notice, the Offeree Stockholders shall have the right to elect to purchase at the price and on the terms and conditions stated in the Sale Notice, either (i) all of the Subject Securities described in the Sale Notice or (ii) a portion of Subject Securities that would allow the Company to avoid such Controlled Company Event. In the event that the Offeree Stockholders elect to purchase any of the Subject Securities, the Offeree Stockholders shall so notify the Selling Stockholder within ten (10) Business Days (the “Option Period”) after the receipt by such party of the Sale Notice. Any such election shall be made by written notice (a “Notice of Election”) to the Selling Stockholder.

(c) If a Notice of Election shall have been delivered to the Selling Stockholder, the Selling Stockholder shall sell such Subject Securities designated in the Notice of Election to the Offeree Stockholders at the price and on the terms and conditions stated in the Sale Notice; provided that if more than one Offeree Stockholder delivers a Notice of Election, the Subject Securities shall be sold to such Offeree Stockholders pro rata on the basis of the number of Subject Securities that each such Offeree Stockholder elected to purchase as set forth in such Offeree Stockholder’s Notice of Election.

(d) The closing of the sale of any Subject Securities to the Offeree Stockholders shall take place at the offices of the Company, or such other location as the parties to the sale may mutually select, on a date the parties may mutually select, no later than fifteen

16

(15) Business Days following the expiration of the Option Period (or upon the expiration of such longer period required to obtain any necessary regulatory approvals). At such closing, the Selling Stockholder shall deliver a certificate or certificates for the Subject Securities to be sold, accompanied by stock powers with signatures guaranteed and all necessary stock transfer taxes paid and stamps affixed, if necessary, against receipt of the purchase price therefor by certified or official bank check or by wire transfer of immediately available funds.

(e) If the Offeree Stockholders (and/or their assignees) do not elect to purchase the Subject Securities designated in the Sale Notice by the end of the Option Period, such Subject Securities may be sold to any Person for a period of 180 days following the expiration of the Option Period at a price not lower than the price specified in the Sale Notice and on other terms and conditions not more favorable to the purchaser than those specified in the Sale Notice; provided, however, that the preceding restrictions on the price and terms and conditions of any such sale shall not apply to sales made pursuant to an effective registration statement under the Securities Act, pursuant to Rule 144 of the Securities Act or otherwise, in each case based on the prevailing market price of the Subject Securities on the Exchange or any other public trading medium at the time that any such sale is effected. Any such Subject Securities not sold by such 180th day shall again be subject to the restrictions contained in this Section 3.2.

(f) The provisions of this Section 3.2 shall terminate upon the occurrence of a Controlled Company Event as a result of the sale of Equity Securities in accordance with this Section 3.2 or otherwise.

SECTION 3.3. Subscription Rights. (a) Each Stockholder shall have the right to purchase its Subscription Right Pro Rata Share (as defined below) of newly issued Equity Securities that the Company may from time to time following the Initial Public Offering propose to issue (a “New Issuance”). A Stockholder’s “Subscription Right Pro Rata Share” shall be, at any given time, that proportion, calculated prior to any proposed new issuance, which the number of Equity Securities owned by such Stockholder at such time bears to the total number of Equity Securities outstanding at such time, including in each case the number of shares of Common Stock for which any outstanding partnership interests of the Operating Partnership are then exchangeable.

(b) In the event the Company proposes to undertake a New Issuance, it shall give the Stockholders a written notice (the “Notice of Issuance”) of its intention to sell such Equity Securities, the price, the identity of the purchaser and the principal terms upon which the Company proposes to issue the same. Subject to Section 3.3(a), each Stockholder shall have ten (10) Business Days from the delivery date of any Notice of Issuance to elect to purchase a number of Equity Securities up to its Subscription Right Pro Rata Share of Equity Securities (in each case calculated prior to the issuance) for the price and upon the terms specified in the Notice of Issuance by giving written notice to the Company and stating therein the number of Equity Securities to be purchased.

(c) In the event that any Stockholder fails to purchase all of its Subscription Right Pro Rata Share pursuant to this Section 3.3, the Company shall have 180 days after the date of the Notice of Issuance to consummate the sale of the Equity Securities with respect to

17

which such Stockholder’s subscription right was not exercised, at or above the price and upon terms not more favorable to the purchasers of such Equity Securities than the terms specified in the initial Notice of Issuance given in connection with such sale; provided, however, that the preceding restrictions on the price and terms and conditions of any such sale shall not apply to sales based on the prevailing market price of such Equity Securities on the Exchange or any other public trading medium at the time that any such sale is effected.

(d) The parties hereby agree that the subscription rights described in this Section 3.3 shall not be exercisable with respect to any issuance by the Company or any Subsidiary of the Company of the following securities:

(i) any issuance of securities to officers, employees or directors of the Company in connection with such person’s employment or director arrangements with the Company pursuant to any employee benefit plan of the Company adopted by the Board; or

(ii) any issuance of securities in connection with the right of any holder of partnership units in the Operating Partnership, pursuant to the terms of the Charter and the Limited Partnership Agreement, to exchange such partnership units for shares of Common Stock;

(iii) any issuance of securities to holders of Class C common stock of the Company, in connection with the right of such holders, pursuant to the terms of the Charter, to convert their shares of Class C common stock of the Company into shares of Common Stock; or

(iv) any issuance of securities in accordance with the Tax Receivable Agreement.

SECTION 3.4. Void Transfers. Any Transfer or attempted Transfer of Equity Securities in violation of any provision of this Agreement shall be void.

ARTICLE IV

MISCELLANEOUS

SECTION 4.1. Stockholder Indemnification; Reimbursement of Expenses.

(a) To the fullest extent permitted by law, the Company agrees to indemnify and hold harmless each Stockholder, their respective stockholders, directors, members, managers, partners, officers and employees and their Affiliates (and controlling persons thereof, and the respective stockholders, directors, members, managers, partners, officers and employees and Affiliates of such controlling persons) (each, a “Stockholder Indemnitee”) from and against any and all liability, including, without limitation, all obligations, costs, fines, penalties, claims, actions, injuries, demands, suits, judgments, proceedings, investigations, arbitrations (including stockholder claims, actions, injuries, demands, suits, judgments, proceedings, investigations or arbitrations) and reasonable expenses, including reasonable accountant’s and reasonable attorney’s fees and expenses (together the “Losses”), as incurred by such Stockholder

18

Indemnitee before or after the date of this Agreement and arising out of, resulting from, or relating to (i) such Stockholder Indemnitee’s purchase and/or ownership of any Equity Securities or (ii) any litigation to which any Stockholder Indemnitee is made a party in its capacity as a Stockholder or owner of securities (or a partner, director, officer, member, manager, employee, Affiliate or controlling person of any Stockholder Indemnitee) of the Company; and will reimburse each Stockholder Indemnitee for any legal and other expenses reasonably incurred in connection with investigating and defending or settling any such obligation, cost, fine, penalty, claim, action, injury, demand, suit, judgment, proceeding, investigation or arbitration; provided that the foregoing indemnification rights in this Section 4.1 shall not be available to the extent, but only to the extent, that (a) any such Losses are incurred as a direct result of such Stockholder Indemnitee’s willful misconduct or gross negligence; (b) any such Losses are incurred as a direct result of non-compliance by such Stockholder Indemnitee with any laws or regulations applicable to any of them; (c) any such Losses are incurred as a direct result of non-compliance by such Stockholder Indemnitee with its obligations under this Agreement or any Transaction Agreements or any related agreements or instruments to which such Stockholder Indemnitee is or becomes a party or otherwise becomes bound (for the avoidance of doubt, this provision shall not affect any indemnification or other rights or obligations arising under any such Transactions Agreements or any related agreements or instruments); or (d) subject to the rights of contribution provided for below, to the extent indemnification for any Losses would violate any applicable law, regulation or public policy. For purposes of this Section 4.1, none of the circumstances described in the limitations contained in the proviso in the immediately preceding sentence shall be deemed to apply absent a final non-appealable judgment of a court of competent jurisdiction to such effect, in which case to the extent any such limitation is so determined to apply to any Stockholder Indemnitee as to any previously advanced indemnity payments made by the Company under this Section 4.1, then such payments shall be promptly repaid by such Stockholder Indemnitee to the Company. The rights of any Stockholder Indemnitee to indemnification hereunder will be in addition to any other rights any such party may have under this Agreement or any other agreement or instrument referenced above or any other agreement or instrument to which such Stockholder Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under law or regulation. In the event of any payment of indemnification pursuant to this Section 4.1, so long as any Stockholder Indemnitee is fully indemnified for all Losses, the Company will be subrogated to the extent of such payment to all of the related rights of recovery of the Stockholder Indemnitee to which such payment is made against all other Persons. Such Stockholder Indemnitee shall execute all papers reasonably required to evidence such rights. The Company will be entitled at its election to participate in the defense of any third party claim upon which indemnification is due pursuant to this Section 4.1 or to assume the defense thereof, with counsel reasonably satisfactory to such Stockholder Indemnitee unless, in the reasonable judgment of the Stockholder Indemnitee, a conflict of interest between the Company and such Stockholder Indemnitee may exist, in which case such Stockholder Indemnitee shall have the right to assume its own defense and the Company shall be liable for all reasonable expenses therefor. Except as set forth above, should the Company assume such defense all further defense costs of the Stockholder Indemnitee in respect of such third party claim shall be for the sole account of such party and not subject to indemnification hereunder unless (i) the Company agrees to pay such costs or (ii) the Company fails promptly to assume, or in the event of a conflict of interest cannot assume, the defense of such claim or proceeding or fails to employ counsel reasonably satisfactory to such Stockholder Indemnitee, in

19

which case such Stockholder Indemnitee shall have the right to employ counsel and to assume the defense of such claim or proceeding. The Company will not without the prior written consent of the Stockholder Indemnitee consent to the entry of any judgment or effect any settlement of any threatened or pending third party claim in which such Stockholder Indemnitee is, or could have been, a party and be entitled to indemnification hereunder unless such settlement solely involves the payment of money and includes an unconditional release, in form and substance satisfactory to such Stockholder Indemnitee, of such Stockholder Indemnitee from all liability and claims that are the subject matter of such claim. If the indemnification provided for above is unavailable in respect of any Losses, then the Company, in lieu of indemnifying an Stockholder Indemnitee, shall contribute to the amount paid or payable by such Stockholder Indemnitee in such proportion as is appropriate to reflect the relative fault of the Company and such Stockholder Indemnitee in connection with the actions which resulted in such Losses, as well as any other equitable considerations. The relative fault of a Stockholder Indemnitee, on the one hand, and the Company, on the other hand, shall be determined by reference to, among other things, whether any action in question has been taken by such Stockholder Indemnitee or the Company, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action.

(b) The Company agrees to pay or reimburse (i) the Stockholders for (A) all reasonable costs and expenses (including reasonable attorneys fees, charges, disbursements and expenses) incurred in connection with any amendment, supplement, modification or waiver of any of the terms or provisions of this Agreement, the Transaction Agreements or any related agreements, and (B) in connection with any stamp, transfer, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement; and (ii) each Stockholder for all costs and expenses of such Stockholder (including reasonable attorneys fees, charges, disbursements and expenses) incurred in connection with (1) the consent to any departure by the Company or any of its Subsidiaries from the terms of any provision of this Agreement and (2) the enforcement or exercise by such Stockholder of any right granted to it or provided for hereunder.

SECTION 4.2. Effectiveness; Termination. This Agreement shall become effective upon consummation of the Initial Public Offering. Subject to the early termination of any provision as a result of an amendment to this Agreement agreed to by the Company and the Stockholders as provided under Section 4.3, this Agreement will terminate with respect to each Stockholder when such Stockholder no longer owns any Equity Securities of the Company; provided that (i) the provisions of Article II shall, with respect to each Stockholder, terminate as provided in the applicable Section of Article II, (ii) the provisions of Section 3.2 shall terminate as provided therein and (iii) Sections 3.1, 3.4, 4.1 and 4.3 of this Agreement shall not terminate and shall survive any termination of this Agreement. Nothing herein shall relieve any party from any liability for the breach of any of the agreements set forth in this Agreement.

SECTION 4.3. Amendments and Waivers. Except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective without the written approval of the Company and each Stockholder; provided, that any Stockholder may waive (in writing) the benefit of any provision of this Agreement with respect to itself for any purpose. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

20

SECTION 4.4. Successors, Assigns and Transferees. Except as otherwise provided in Section 3.1(b), this Agreement shall bind and inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. Stockholders may assign their respective rights and obligations hereunder to any Transferees only to the extent expressly provided herein.

SECTION 4.5. Legend. (a) All certificates or book entries, as the case may be, representing the Equity Securities held by each Stockholder shall bear a legend substantially in the following form:

THE SECURITIES REPRESENTED BY THIS [CERTIFICATE][BOOK ENTRY] ARE SUBJECT TO A STOCKHOLDERS’ AGREEMENT (A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY). NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS [CERTIFICATE][BOOK ENTRY] MAY BE MADE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH STOCKHOLDERS’ AGREEMENT AND (A) PURSUANT TO A REGISTRATION STATEMENT EFFECTIVE UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER. THE HOLDER OF THE SECURITIES REPRESENTED BY THIS [CERTIFICATE][BOOK ENTRY], BY ACCEPTANCE OF SUCH SECURITIES, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF SUCH STOCKHOLDERS’ AGREEMENT.

(b) Upon the sale of any Equity Securities to a person other than a Permitted Transferee pursuant to (i) an effective registration statement under the Securities Act or pursuant to Rule 144 under the Securities Act or (ii) another exemption from registration under the Securities Act or upon the termination of this Agreement, the certificates or book entries representing such Equity Securities shall be replaced, at the expense of the Company, with certificates or book entries not bearing the legends required by this Section 4.5; provided that the Company may condition such replacement of certificates or book entries under clause (ii) upon the receipt of an opinion of securities counsel reasonably satisfactory to the Company.

SECTION 4.6. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified; (b) when sent by confirmed facsimile if sent during normal business hours of the recipient or, if not, then on the next Business Day, provided that a copy of such notice is also sent via nationally recognized overnight courier, specifying next day delivery, with written verification of receipt; (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one (1) Business Day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

SECTION 4.7. Further Assurances. At any time or from time to time after the date hereof, the parties agree to cooperate with each other, and at the request of any other party, to execute and deliver any further instruments or documents and, to the fullest extent permitted by law, to take all such further action as the other party may reasonably request in order to evidence or effectuate the consummation of the transactions contemplated hereby and to otherwise carry out the agreements and the intent of the parties hereunder.

SECTION 4.8. Entire Agreement. Except as otherwise expressly set forth herein, this Agreement, together with the other agreements entered into by the parties hereto in connection with the Initial Public Offering and filed as exhibits to the Registration Statement (collectively, the “Transaction Agreements”) embodies the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties, written or oral, that may have related to the subject matter hereof in any way.

SECTION 4.9. Enabling Clause. To the fullest extent permitted by law the Company hereby covenants and agrees to cause the Charter and By-laws to give effect to the terms and provisions contained in this Agreement. To the fullest extent permitted by law, each of the parties covenants and agrees to vote their Equity Securities and to take any other action reasonably requested by the Company or any Stockholder to amend the Charter and By-laws so as to give full effect to and to avoid any conflict with the provisions hereof.

SECTION 4.10. Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character on the part of any party hereto of any breach, default or noncompliance under this Agreement or any waiver on such party’s part of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. No waiver of any default with respect to any provision, condition or requirement of this

23

Agreement shall be deemed to be a continuing waiver in the future or a waiver of any other provision, condition or requirement hereof. All remedies, either under this Agreement, by law, or otherwise afforded to any party, shall be cumulative and not alternative.

SECTION 4.11. Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed in all respects by the laws of the State of Delaware. No suit, action or proceeding with respect to this Agreement may be brought in any court or before any similar authority other than in a court of competent jurisdiction in the State of New York, and the parties hereto hereby submit to the exclusive jurisdiction of such courts for the purpose of such suit, proceeding or judgment. Each party hereto hereby irrevocably waives any right it may have had to bring such an action in any other court, domestic or foreign, or before any similar domestic or foreign authority. Each of the parties hereto hereby irrevocably and unconditionally waives trial by jury in any legal action or proceeding in relation to this Agreement and for any counterclaim therein.

SECTION 4.12. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

SECTION 4.13. Enforcement. Each party hereto acknowledges that money damages would not be an adequate remedy in the event that any of the covenants or agreements in this Agreement are not performed in accordance with its terms, and it is therefore agreed that in addition to and without limiting any other remedy or right it may have, the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any such breach and enforcing specifically the terms and provisions hereof.

SECTION 4.14. Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

SECTION 4.15. No Recourse.

24

Stockholder or any current or future member of any Stockholder or any current or future stockholder, director, officer, employee, partner or member of any Stockholder or of any Affiliate or assignee thereof, as such for any obligation of any Stockholder under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.
