2.2 Additional Purchases; Adjustments. The Holder agrees that any additional shares of capital stock, Company Common Stock or other equity of the Company, and any additional Convertible Notes, that the Holder purchases or otherwise acquires or with respect to which the Holder otherwise acquires Beneficial Ownership or voting power after the execution of this Agreement and prior to the earlier of the Termination Date and the Effective Time shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Covered Securities as of the date hereof (and shall be deemed “Covered Securities” for all purposes hereof), and the Holder shall promptly notify Parent of the existence of any such acquired Covered Securities. 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 Company affecting the Covered Securities or any increase in the conversion rate of the Convertible Notes pursuant to the terms thereof, the terms of this Agreement shall apply to the resulting securities.

If any involuntary Transfer of any of the Holder’s Covered Securities shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Covered Securities subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement.

ARTICLE III

AGREEMENT TO VOTE

3.1 Agreement to Vote. Prior to the earlier of the Termination Date and the Effective Time, on and subject to the terms and conditions set forth herein, provided that the Merger Agreement has not been amended by a Restricted Amendment, the Holder irrevocably and unconditionally agrees that such Holder shall, at any meeting (whether annual or special and whether or not an adjourned or postponed meeting), however called, of the stockholders of the Company or the holders of the Convertible Notes or with respect to any written consent of the stockholders of the Company or the holders of the Convertible Notes, appear at such meeting or otherwise cause the Covered Securities to be counted as present thereat for purpose of establishing a quorum and vote, or cause to be voted at such meeting or by written consent, all Covered Securities:

(a) in favor of the adoption of the Merger Agreement and approving any other matters necessary for the consummation of the transactions contemplated by the Merger Agreement, including the Mergers; and

(b) against (i) any Acquisition Proposal or any other transaction, proposal, agreement or action made in opposition to adoption of the Merger Agreement or in competition or that is inconsistent with the Mergers or matters contemplated by the Merger Agreement, (ii) any other action that would reasonably be expected to impede, interfere with, delay, discourage, postpone or adversely affect the Mergers or any of the other transactions contemplated by the Merger Agreement or this Agreement or any transaction that results in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of the Company or any of its Subsidiaries under the Merger Agreement, and (iii) any change in the corporate structure, business, present capitalization or dividend policy of the Company or any amendment or other change to the Company Charter or the Company Bylaws (collectively, the “Company Documents”), except as expressly permitted pursuant to the Merger Agreement.

Any attempt by the Holder to vote, consent or express dissent with respect to (or otherwise to utilize the voting power of) the Covered 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 Covered 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 Covered Securities in accordance with this Section 3.1.

Notwithstanding anything herein to the contrary in this Agreement, this Section 3.1 shall not require the Holder to be present (in person or by proxy) or vote (or cause to be voted) any of the Covered Securities to amend, modify or waive any provision of the Merger Agreement in a manner that changes the amount or form of the consideration payable in the Mergers pursuant to the terms of the Merger Agreement (the “Merger Consideration”) or imposes any material restrictions on or additional material conditions on the payment of the Merger Consideration, provides for the payment by the Holder of any indemnification or other additional amounts, adds any additional covenants on the activities of the Holder (e.g. restrictive covenants) or extends the Outside Date (collectively, the “Restricted Amendments”). Notwithstanding anything to the contrary in this Agreement, the Holder shall remain free to vote (or execute consents or proxies with respect to) the Covered Securities with respect to any matter other than as set forth in Section 3.1(a) and Section 3.1(b) in any manner the Holder deems appropriate.

3.2 Proxy. The Holder hereby irrevocably appoints as its proxy and attorney-in-fact, Parent, the executive officers of 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 Covered Securities as indicated in Section 3.1 above. The Holder intends this proxy to be irrevocable and unconditional during the term of this Agreement prior to the Effective Time 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 the Holder with respect to the Covered Securities (and the Holder hereby represents that any such proxy is revocable). The proxy granted by the Holder shall be automatically revoked upon the earlier of the Termination Date and the Effective Time and Parent may further terminate this proxy at any time at its sole election by written notice provided to the Holder.

3.3 Effective Registration Statement on Form S-4. Notwithstanding any provision herein to the contrary, there will be no obligation of Holder to vote Covered Securities pursuant to Section 3.1 and Covered Securities cannot be voted pursuant to the proxy in Section 3.2 unless and until after the Registration Statement on Form S-4 as contemplated in Section 5.3 of the Merger Agreement has been declared effective by the Securities and Exchange Commission.

ARTICLE IV

ADDITIONAL AGREEMENTS

4.1 Waiver of Appraisal Rights; Litigation. Unless (a) this Agreement is terminated in accordance with its terms or pursuant to Section 6.5, or (b) the Merger Agreement is amended in a manner that constitutes a Restricted Amendment, in each case without the consent of the Holder, to the fullest extent permitted by Law, the Holder hereby irrevocably and unconditionally waives, and agrees not to exercise, any rights of appraisal (including under Section 262 of the DGCL) relating to the Mergers that the Holder may have by virtue of the ownership of any Covered Securities. The Holder further agrees not to commence, join in, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub Inc., Merger Sub LLC or the Company or any of their respective Affiliates and each of their successors or directors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the transactions contemplated hereby or thereby, including any claim (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the Closing), (b) alleging a breach of any fiduciary duty of the Company Board in connection with the negotiation and entry into the Merger Agreement or the transactions contemplated thereby, or (c) alleging any failure on the part of the Company or Parent to provide information or alleging a material misstatement or omission in the information provided to such Holder in connection with the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the transactions contemplated hereby or thereby, and hereby irrevocably waives any claim or rights whatsoever with respect to any of the foregoing.

4.2 Parent Shares. From the date hereof until the earlier of the Termination Date and the Effective Time, the Holder shall not (a) purchase, acquire Beneficial Ownership of, offer,

pledge, sell, contract to purchase or sell, grant or acquire any option, right or warrant to purchase, give, assign, hypothecate, pledge, encumber, grant or acquire a security interest in, sell or purchase any option or contract to purchase or any option or contract to sell, grant or acquire any option, right or warrant to purchase, lend or otherwise acquire, transfer or dispose of (including through any hedging, derivative or other similar transaction) any economic, voting or other rights in or to shares of Parent Common Stock, or otherwise acquire, transfer or dispose of shares of Parent Common Stock, directly or indirectly, or (b) enter into any swap or other agreement that transfers or results in the acquisition of, in whole or in part, any of the economic consequences of ownership of shares of Parent Common Stock (any such transaction described in clause (a) or (b) above, a “Parent Share Transfer”). Notwithstanding the foregoing, the restrictions set forth in this Section 4.2 shall not apply to any Parent Share Transfer to or with one or more Affiliates of the Holder (A) who is a party to an agreement with Parent with substantially similar terms as this Section 4.2 or (B) if, as a condition to such Parent Share Transfer, the counterparty agrees in writing to be bound by this Section 4.2 and delivers a copy of such executed written agreement to Parent prior to the consummation of such Parent Share Transfer. Nothing herein prohibits Holder or any Affiliate of the Holder from taking any of the actions in this Section 4.2 to the extent such activities are in the ordinary course of such Person’s business consistent with past practice, are not related to Holder’s Beneficial Ownership in the Company or the Mergers, including where Parent Common Stock is a component of any exchange-traded fund (ETF) or similar vehicle, and are not undertaken for the purpose of affecting in any manner the trading price of shares of Parent Common Stock.

4.3 Further Assurances. The Holder agrees that, during the term of this Agreement, the Holder shall and shall cause such Holder’s controlled Affiliates to take no action that would reasonably be expected to adversely affect or delay the ability to perform the Holder’s respective covenants and agreements under this Agreement.

4.4 Fiduciary Duties. The Holder is entering into this Agreement solely in such Holder’s capacity as the record or Beneficial Owner of the Covered Securities and nothing herein is intended to or shall limit or affect any actions taken by the Holder or any of the Holder’s designees, as applicable, serving in his or her capacity as a director or officer of the Company or any of its Subsidiaries. The taking of any actions (or failures to act) by the Holder or the Holder’s designees, as applicable, serving as a director or officer of the Company or any of its Subsidiaries (in such capacity as a director or officer) shall not be deemed to constitute a breach of this Agreement. For the avoidance of doubt, all action taken by a Holder hereunder shall be deemed solely in such Holder’s capacity as the record or Beneficial Owner of the Covered Securities and shall not be imputed to, and shall not be considered to be any action of, such designees of the Holder.

ARTICLE V

SUPPLEMENTAL INDENTURE TO SENIOR NOTES INDENTURE

5.1 Amendment to Senior Notes Indenture. Each Senior Notes Holder represents and warrants that it is the Beneficial Owner of the principal amount of Senior Notes reflected on the Senior Notes Holder’s signature page hereto. In connection with the Mergers, the Company proposes to amend and supplement the Senior Notes Indenture as contemplated in the Third Supplemental Indenture so to allow for the Senior Notes to be repaid upon consummation of the

Mergers in a combination of cash and shares of Parent Common Stock. Holder, if a Senior Notes Holder, herein provides its consent and approval of the amendments set forth in the Third Supplemental Indenture. Holder, if a Senior Notes Holder, further hereby irrevocably agrees, as soon as practical following the date of this Agreement, (i) to coordinate with the Trustee under the Indenture, the Holder’s DTC participants and CEDE & CO as necessary, (ii) to execute and deliver any and all consents, certificates, documents, agreements and instruments, in each case as may be necessary to (x) make the Third Supplemental Indenture a valid and enforceable instrument, (y) cause the Third Supplemental Indenture to become effective and binding on the Senior Notes Holder, the Company and the trustee under the Senior Notes Indenture and (z) to amend the Senior Notes Indenture as set forth in the Third Supplemental Indenture and (iii) to cause any transferee of the Senior Notes to take the foregoing actions.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES OF THE HOLDER

6.1 Representations and Warranties. The Holder hereby represents and warrants as follows:

(a) Ownership. The Holder has, with respect to the Covered Securities, and at all times during the term of this Agreement will continue to have, Beneficial Ownership of, good and valid title to and full and exclusive power to vote, issue instructions with respect to the matters set forth in Article III, agree to all of the matters set forth in this Agreement and, subject to the limitations contained in this Agreement, to Transfer the Covered Securities. The Covered Securities constitute all of the shares of Company Common Stock and Convertible Notes owned of record or Beneficially Owned by the Holder as of the date hereof, and all of the Covered Securities are held by the Holder free and clear of all Encumbrances, other than Encumbrances arising under the Company Documents. Other than this Agreement and Encumbrances arising under the Company Documents, (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 Covered Securities and (ii) no Person has any contractual or other right or obligation to purchase or otherwise acquire any of the Covered Securities.

(b) Organization; Authority. If the Holder is an entity, it is duly organized, validly existing and in good standing under the Laws of its jurisdiction of formation. If the Holder is an individual, he or she has full power and authority and is duly authorized to make, enter into and carry out the terms of this Agreement and to perform the Holder’s obligations hereunder. This Agreement has been duly and validly executed and delivered by the Holder and (assuming due authorization, execution and delivery by 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 applicable bankruptcy, insolvency, reorganization, moratorium or similar Laws affecting creditors’ rights generally and by general principles of equity (regardless of whether considered in a proceeding in equity or at law)), 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 (iii) conflict with, or result in a breach or default under, any agreement or instrument to which the Holder is a party or any term or condition of its certificate of incorporation, bylaws, certificate of formation, limited liability company agreement or comparable organizational documents, as and if 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 the Holder’s obligations hereunder.

(d) Consents and Approvals. The execution and delivery by the Holder of this Agreement, and the performance of the Holder’s obligations hereunder, do not require the Holder 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. As of the date hereof, there is no action, suit, investigation, complaint or other proceeding pending, or, to the actual knowledge of the Holder, threatened in writing, against the Holder that would prevent the performance by the Holder of its obligations under this Agreement on a timely basis.

(f) Absence of Other Voting Agreements. Except as contemplated by this Agreement, the Holder (i) has not entered into, and shall not enter into at any time prior to the earlier of the Termination Date and the Effective Time, any voting agreement or voting trust with respect to the Covered Securities and (ii) has not granted, and shall not grant at any time prior to the earlier of the Termination Date and the Effective Time, a proxy or power of attorney with respect to the Covered Securities, in either case, which is inconsistent with the Holder’s obligations pursuant to this Agreement. None of the Covered Securities are subject to any pledge agreement pursuant to which the Holder does not retain sole and exclusive voting rights with respect to the Covered Securities subject to such pledge agreement at least until the occurrence of an event of default under the related debt instrument.

ARTICLE VII

MISCELLANEOUS

7.1 No Solicitation. The Holder agrees that such Holder shall not, and shall cause such Holder’s controlled Affiliates not to, directly or indirectly, take any of the actions listed in clauses (i) or (ii) of Section 5.2(a) of the Merger Agreement (without giving effect to any amendment or modification of such clauses after the date hereof that would impose more burdensome restrictions on such Holder). The Holder shall, and shall cause such Holder’s controlled Affiliates to, immediately cease and cause to be terminated all existing discussions and negotiations with any Person conducted heretofore with respect to any Acquisition Proposal or potential Acquisition Proposal. In addition, the Holder agrees to be subject to Section 5.2(c) of the Merger Agreement (without giving effect to any amendment or modification of such clause after the date hereof that would impose more burdensome restrictions on such Holder) as if the Holder were “the Company” thereunder. Notwithstanding the foregoing, to the extent the Company complies with its obligations under Section 5.2 of the Merger Agreement and participates in discussions or

negotiations with a Person regarding an Acquisition Proposal, the Holder or any of such Holder’s controlled Affiliates may engage in discussions or negotiations with such Person to the extent that the Company can act under Section 5.2 of the Merger Agreement.

7.2 Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated by this Agreement may only be brought against, the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. Except to the extent a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party in this Agreement and not otherwise), no past, present or future director, manager, officer, employee, incorporator, member, partner, equityholder, Affiliate, agent, attorney, advisor, consultant or Representative or Affiliate of any of the foregoing (each, a “Holder Related Party”) shall have any liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of or made under this Agreement or in respect of any oral representations made or alleged to have been made in connection herewith (whether for indemnification or otherwise) or of or for any claim based on, arising out of, or related to this Agreement or the transactions contemplated by this Agreement. Parent acknowledges that no Holder nor any Holder Related Party has made, and Parent has not relied upon, any representation related to the matters contemplated by this Agreement, except as set forth in Article VI.

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

7.4 Disclosure. The Holder consents to and authorizes the publication and disclosure by the Company and Parent of the Holder’s identity and holding of Covered Securities, and the terms of this Agreement (including, for avoidance of doubt, the disclosure of this Agreement), in any press release, the Form S-4 (including the Proxy Statement) and any other disclosure document required in connection with this Agreement, the Merger Agreement, the Mergers and the transactions contemplated by the Merger Agreement.

7.5 Termination. This Agreement shall terminate upon the date the Merger Agreement is validly terminated in accordance with its terms (such date, the “Termination Date”). Neither the provisions of this Section 7.5 nor the termination of this Agreement shall relieve (a) any party hereto from any liability of such party to any other party incurred prior to such termination or (b) 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 the Holder from any liability arising out of or in connection with a breach of this Agreement.

7.6 Amendment. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each party hereto.

(a) extend the time for the performance of any of the obligations or other acts of the other party hereunder;

(b) waive any inaccuracies in the representations and warranties of the other party contained in this Agreement or in any document delivered pursuant to this Agreement; or

(c) waive compliance with any of the covenants, obligations or conditions of the other party contained in this Agreement;

provided, however, that, in each case, such extension or waiver or any consent given under this Agreement shall be valid only if it 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 any party in exercising any right, power or privilege under this Agreement or any of the documents referred to in this Agreement shall operate as a waiver of such right, power or privilege, nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise of any such right, power or privilege or the exercise of any other right power or privilege. To the maximum extent permitted by applicable Law, (a) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (b) no notice to or demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

7.9 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.
