ARTICLE I

GENERAL

1.1 Definitions. Capitalized terms used but not defined herein shall have the meanings set forth in the Merger Agreement.

“Beneficially Own” or “Beneficial Ownership” has the meaning assigned to such term in Rule 13d-3 under the Exchange Act, and a Person’s beneficial ownership of securities shall be calculated in accordance with the provisions of such Rule (in each case, irrespective of whether or not such Rule is actually applicable in such circumstance). For the avoidance of doubt, Beneficially Own and Beneficial Ownership shall also include record ownership of securities.

“Beneficial Owners” shall mean Persons who Beneficially Own the referenced securities.

ARTICLE II

ADDITIONAL SECURITIES

2.1 Additional Purchases; Adjustments. Each Holder agrees that any shares of Parent Common Stock or Opco LP Units and any other shares of capital stock or other equity securities of Parent or Opco LP that such Holder purchases or otherwise acquires or with respect to which such Holder otherwise acquires voting power after the execution of this Agreement and prior to the Termination Date shall be subject to the terms and conditions of this Agreement to the same extent as if such shares of capital stock or other equity securities constituted Securities as of the date hereof. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares or the like of the capital stock of the Parent affecting the Securities, the terms of this Agreement shall apply to the resulting securities.

ARTICLE III

AGREEMENT TO VOTE; PROXY; WRITTEN CONSENT

3.1 Agreement to Vote. From the date of this Agreement until the Termination Date, each Holder irrevocably and unconditionally agrees that, at any meeting of the stockholders of Parent (whether annual or special and whether or not an adjourned or postponed meeting, however called), or in connection with any written consent of the stockholders of Parent or unitholders of Opco LP, such Holder shall:

(a) appear at such meeting or otherwise cause all of the Holder’s applicable Securities owned as of the record date for such meeting to be counted as present thereat for purpose of establishing a quorum;

2

(b) vote (or execute and return an action by written consent), or cause to be voted at such meeting in person or by proxy (or validly execute and return and cause such consent to be granted with respect to), all of the Holder’s applicable Securities owned as of the record date for such meeting (or the date that any written consent is executed by the Holder) in favor of (i) adoption of the Merger Agreement; (ii) the approval of the Parent Merger and the other Transactions; (iii) any amendment and/or restatement of the Organizational Documents of Parent or any of its Subsidiaries necessary to effect the consummation of the Transactions as contemplated by the Merger Agreement; and (iv) any other proposals agreed to by Parent and the Company which are necessary and appropriate in connection with the Transactions or to effectuate the intent of the foregoing clauses (i) through (iii); and

(c) vote (or execute and return an action by written consent), or cause to be voted at such meeting in person or by proxy (or validly execute and return and cause such consent to be granted with respect to), all of the Holder’s applicable Securities owned as of the record date for such meeting (or the date that any written consent is executed by the Holder) against (i) any agreement, transaction or proposal that relates to a Parent Competing Proposal or any other transaction, proposal, agreement or action made in opposition to adoption of the Merger Agreement or in competition or inconsistent with the Mergers or matters contemplated by the Merger Agreement; (ii) any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of Parent or any of its Subsidiaries contained in the Merger Agreement or of the Holder contained in this Agreement; (iii) any action or agreement that would reasonably be expected to result in (x) any condition to the consummation of the Mergers set forth in Article VII of the Merger Agreement not being fulfilled or (y) any change to the voting rights of any class of shares of capital stock of Parent (including any amendments to Parent’s Organizational Documents); and (iv) any other action that could reasonably be expected to impede, interfere with, delay, discourage, postpone or adversely affect any of the transactions contemplated by the Merger Agreement, including the Mergers, or this Agreement. Any attempt by the Holder to vote, consent or express dissent with respect to (or otherwise to utilize the voting power of), the Holder’s applicable Securities in contravention of this Section 3.1 shall be null and void ab initio. If the Holder is the Beneficial Owner, but not the holder of record, of any Securities, the Holder agrees to take all actions necessary to cause the holder of record and any nominees to vote (or exercise a consent with respect to) all of such Securities in accordance with this Section 3.1.

Notwithstanding anything herein to the contrary in this Agreement, this Section 3.1 shall not require any Holder to be present (in person or by proxy) or vote (or cause to be voted), any of the applicable Securities to amend, modify or waive any provision of the Merger Agreement in a manner that reduces the amount, changes the form of the Merger Consideration payable, extends the End Date or otherwise adversely affects such Holder of the Company (in its capacity as such) in any material respect. Notwithstanding anything to the contrary in this Agreement, but subject to Section 3.2, each Holder shall remain free to vote (or execute consents or proxies with respect to) the applicable Securities with respect to any matter other than as set forth in Section 3.1(a) and Section 3.1(c) in any manner such Holder deems appropriate, including in connection with the election of directors of the Company. The obligations of the Holders specified in this Section 3.1 shall apply whether or not the Mergers or any action described above is recommended by the Parent Board.

3

3.2 Proxy. Each Holder hereby irrevocably appoints as its proxy and attorney-in-fact, Parent and any person designated in writing by Parent, each of them individually, with full power of substitution and resubstitution, to consent to or vote the applicable Securities as indicated in Section 3.1 above. Each Holder intends this proxy to be irrevocable and unconditional, and coupled with an interest and will take such further action or execute such other instruments as may be reasonably necessary to effect the intent of this proxy, and hereby revokes any proxy previously granted by such Holder with respect to such Securities (and such Holder hereby represents that any such proxy is revocable). The proxy granted by each Holder shall be automatically revoked upon the occurrence of the earlier of the Effective Date or the Termination Date and the Company may further terminate this proxy at any time at its sole election by written notice provided to each Holder. Notwithstanding anything to the contrary contained in this Agreement or the Merger Agreement, the proxy granted by each Holder pursuant to this Section 3.2 shall only be effective immediately prior to the voting of such Securities.

3.3 [Reserved.]

3.4 Agreement to Deliver Written Consent. Each Holder irrevocably and unconditionally agrees that, promptly following the time at which the Registration Statement becomes effective (and, in any event within one (1) Business Day), it shall cause the Written Consent to be executed and delivered to Parent with respect to the applicable Securities as of the date thereof entitled to consent thereto.

ARTICLE IV

ADDITIONAL AGREEMENTS

4.1 [Reserved.]

4.2 Further Assurances. Each Holder agrees that until the Termination Date, such Holder shall and shall cause its Subsidiaries to take no action that would reasonably be likely to adversely affect or delay the ability to perform its respective covenants and agreements under this Agreement. Notwithstanding the foregoing, nothing in this Agreement shall be deemed to restrict the ability of any Holder to transfer or otherwise enter into a transaction with respect to its Securities at any time in its sole discretion.

4.3 Fiduciary Duties. Each Holder is entering into this Agreement solely in its capacity as the record or Beneficial Owner of the Securities and nothing herein is intended to or shall limit or affect any actions taken by any of such Holder’s designees serving in his or her capacity as a director of Parent (or a Subsidiary of Parent). The taking of any actions (or failures to act) by each Holder’s designees serving as a director of Parent (in such capacity as a director) shall not be deemed to constitute a breach of this Agreement.

ARTICLE V

REPRESENTATIONS AND WARRANTIES OF HOLDER

5.1 Representations and Warranties. Each Holder, severally and not jointly, hereby represents and warrants as follows:

(a) Ownership. The Holder has, with respect to the Securities, Beneficial Ownership of, good and valid title to and full and exclusive power to vote, and issue instructions with respect to the matters set forth in Article III. The Securities constitute all of the shares of Parent Common Stock and Opco LP Units owned of record or beneficially by the Holder as of the date hereof. Other than this Agreement and except as set forth in the Organizational Documents of Opco LP, (i) there are no agreements or arrangements of any kind, contingent or otherwise, to which the Holder is a party obligating the Holder to transfer or cause to be transferred to any person any of the Securities or otherwise enter into a transaction with respect to its Securities and (ii) no Person has any contractual or other right or obligation to purchase or otherwise acquire any of the Securities.

(b) Organization; Authority. As applicable to each Holder, Royal Aggregator is a limited partnership, and Rock Ridge is a limited liability company, each duly organized, validly existing and in good standing under the Laws of its jurisdiction of formation. The Holder has full power and authority and is duly authorized to make, enter into and carry out the terms of this Agreement and to perform its obligations hereunder. This Agreement has been duly and validly executed and delivered by the Holder and (assuming due authorization, execution and delivery by the Company and Parent) constitutes a valid and binding agreement of the Holder, enforceable against the Holder in accordance with its terms (except in all cases as such enforceability may be limited by Creditors’ Rights), and no other action is necessary to authorize the execution and delivery by the Holder or the performance of the Holder’s obligations hereunder.

(c) No Violation. The execution, delivery and performance by the Holder of this Agreement will not (i) violate any provision of any Law applicable to the Holder; (ii) violate any order, judgment or decree applicable to the Holder or any of its affiliates; or (iii) conflict with, or result in a breach or default under, any agreement or instrument to which the Holder or any of its affiliates is a party or any term or condition of its certificate of formation, limited liability company agreement or comparable Organizational Documents, as applicable, except where such conflict, breach or default would not reasonably be expected to, individually or in the aggregate, have an adverse effect on the Holder’s ability to satisfy its obligations hereunder.

(d) Consents and Approvals. The execution and delivery by the Holder of this Agreement does not, and the performance of the Holder’s obligations hereunder, require the Holder or any of its affiliates to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any person or Governmental Entity, except such filings and authorizations as may be required under the Exchange Act.

(e) Absence of Litigation. To the knowledge of the Holder, as of the date hereof, there is no Proceeding pending against, or threatened in writing against the Holder that would prevent the performance by the Holder of its obligations under this Agreement or to consummate the transactions contemplated hereby or by the Merger Agreement, including the Mergers, on a timely basis.

(f) Absence of Other Voting Agreements. Other than pursuant to Permitted Encumbrances, none of the Securities is subject to any voting trust, proxy or other agreement, arrangement or restriction with respect to voting, in each case, that is inconsistent with this Agreement, except as contemplated by this Agreement. None of the Securities is subject to any pledge agreement pursuant to which the Holder does not retain sole and exclusive voting rights with respect to the Securities subject to such pledge agreement at least until the occurrence of an event of default under the related debt instrument.

6.1 [Reserved.]

6.2 No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Company any direct or indirect ownership or incidence of ownership of or with respect to the Securities. All rights, ownership and economic benefits of and relating to the Securities shall remain vested in and belong to each Holder, as applicable, and the Company shall not have any authority to manage, direct, restrict, regulate, govern or administer any of the policies or operations of Parent or exercise any power or authority to direct any Holder in the voting or disposition of any Securities, except as otherwise expressly provided herein.

6.3 Disclosure. Each Holder consents to and authorizes the publication and disclosure by the Company and Parent of such Holder’s identity and holding of Securities, and the terms of this Agreement (including, for avoidance of doubt, the disclosure of this Agreement), in any press release, the Registration Statement, including the Joint Information Statement/Proxy Statement/Prospectus, as applicable, and any other disclosure document required in connection with the Merger Agreement, the Mergers and the transactions contemplated by the Merger Agreement.

6.4 Termination. This Agreement shall terminate at the earliest of (i) the date the Merger Agreement is validly terminated in accordance with its terms, (ii) the Effective Time, (iii) an amendment to the Merger Agreement without the prior written consent of each Holder that (A) reduces the consideration payable in the Parent Merger, on a per share of Parent Common Stock basis, (B) changes the form of consideration payable in the Parent Merger to the holders of Parent Common Stock, or (C) extends the outside date under the Merger Agreement (except if such extension is explicitly provided for in, and effected pursuant to, the Merger Agreement) and (iv) mutual consent of the parties hereto (such date, the “Termination Date”). Neither the provisions of this Section 6.4 nor the termination of this Agreement shall relieve (x) any party hereto from any liability of such party to any other party incurred prior to such termination or (y) any party hereto from any liability to any other party arising out of or in connection with a breach of this Agreement. Nothing in the Merger Agreement shall relieve a Holder from any liability arising out of or in connection with a breach of this Agreement.

provided, that, in each case, such waiver is made in writing and signed by the party (or parties) against whom the waiver is to be effective.

Notwithstanding the foregoing, no failure or delay by the Company or Parent in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. No agreement on the part of a party to any such extension or waiver shall be valid unless set forth in an instrument in writing signed on behalf of such party.

6.8 Expenses. All fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees or expenses, whether or not the Mergers are consummated.
