AGREEMENTS AMONG THE INVESTORS.

2.1 Actions Under the Merger Agreement. Subject to Section 2.2 below and subject to consulting with the other Investors, the Investor or Investors holding a majority of the Commitments and the Rollover Commitment, taken as a whole, in the aggregate (the “Majority Holder”) may cause Parent to take or refrain from taking any action with respect to the Merger Agreement and the transactions contemplated thereby, including: (a) determining that the conditions to closing specified in Sections 6.1 and 6.3 of the Merger Agreement (the “Closing Conditions”) have been satisfied, (b) waiving compliance with any agreements or any Closing Conditions contained in the Merger Agreement, (c) amending, supplementing or modifying the Merger Agreement or (d) terminating the Merger Agreement.

2.2 Non-Consenting Investors.

2.2.1 Notwithstanding anything to the contrary in Section 2.1 above, Parent shall not, and the Majority Holder shall not permit Parent to, (x) modify or amend the Merger Agreement so as to increase the amount or modify the form of the Merger Consideration, decrease the Company Termination Fee or increase the Parent Termination Fee or any other obligations related to the Termination Fee Equity Commitment Letter or (y) amend the terms and conditions of the Merger Agreement in a way that is materially and disproportionately adverse to any Investor relative to any other Investor without such Investor’s consent; provided that in the event that the Majority Holder is willing to agree to, proceed with, or take any action or enter into any agreement (or, in each case, permit Parent or Merger Sub to do so) with respect to such matters, and any Initial or Joining Investor declines to agree to, proceed with, take any such action or enter into any such agreement (or, in each case, to permit Parent or Merger Sub to do so) with respect to such matters, the Majority Holder may nevertheless proceed with such matters by first obtaining (in accordance with Section 2.2.2) Commitments to replace such declining Initial or Joining Investor’s Commitment and then terminating such declining Initial or Joining Investor’s participation in the transaction (such terminated Investor, a “Non-Consenting Investor”) and, in such event, such Non-Consenting Investor shall have no liability or obligations (a) hereunder (other than Section 5 (other than Section 5.10)) or (b) under its Equity Commitment Letters (and the other Initial or Joining Investors shall cause such Non-Consenting Investor to be released from, or indemnified for, any obligation under its Equity Commitment Letters as a condition to any such termination).

2.2.2 In the event that the Majority Holder wishes to terminate a Non-Consenting Investor’s participation in the transaction pursuant to Section 2.2.1 or a Non-Consenting Rollover Investor’s participation in the transaction pursuant to Section 2.2.3, the Initial Investors (that are not Non-Consenting Investors) shall be entitled to fund the amount of equity that is subject to such Non-Consenting Investor’s Commitment or equal to the value of the Rollover Commitment in the case of a Non-Consenting Rollover Investor by increasing their Commitments on a pro rata basis based on their respective Commitments. If, in accordance with the immediately preceding sentence, none or not all of the Non-Consenting Investor’s Commitment (or equity in an amount equal to the value of the Non-Consenting Investor’s Rollover Commitment in the case of a Rollover Investor) is accepted by such Initial Investors, then the Majority Holder shall be entitled to fund the amount of equity that is not accepted by such Initial Investors and/or the Majority Holder may offer the portion of the Non-Consenting Investor’s Commitment (or equity in an amount equal to the value of the Non-Consenting Investor’s Rollover Commitment in the case of a Rollover Investor) that has not been accepted by the Initial Investors (including the Majority Holder), to the other Investors, if applicable, or to a new investor or investors, and will negotiate in good faith the terms of any replacement arrangements.

2.2.3 Notwithstanding anything to the contrary in Section 2.1 above, Parent shall not, and the Majority Holder shall not permit Parent to (directly or indirectly), (x) modify or amend the Merger Agreement so as to increase the amount or modify the form of the Merger Consideration, (y) modify or amend any of the Equity Commitment Letters or this Agreement in any way that would materially and adversely affect the Rollover Investor or (z) amend the terms and conditions of the Merger Agreement in a way that is materially and disproportionately adverse to the Rollover Investor relative to any other Investor without the Rollover Investor’s consent; provided that in the event that the Majority Holder is willing to agree to, proceed with, or take any action or enter into any agreement (or, in each case, permit Parent or Merger Sub to do so) with respect to such matters, and the Rollover Investor declines to agree to, proceed with, take any such action or enter into any such agreement (or, in each case, to permit Parent or Merger Sub to do so) with respect to such matters, the Majority Holder may nevertheless proceed with such matters by first obtaining (in accordance with Section 2.2.2) Commitments to replace the amount of equity equal to the value of the Rollover Commitment and then terminating the Rollover Investor’s participation in the transaction (such terminated Rollover Investor, a “Non-Consenting Rollover Investor”) and, in such event, such Non-Consenting Rollover Investor shall have no liability or obligations (a) hereunder (other than Section 5 (other than Section 5.10)) or (b) under its Rollover Agreement (and the other Investors shall cause such Non-Consenting Rollover Investor to be released from, or indemnified for, any obligation under its Rollover Agreement as a condition to any such termination).

2.3 Failing Investors. Subject to Section 2.2 above, in the event that (a) the Majority Holder determines that the Closing Conditions are satisfied or validly waived or (b) an award of specific performance to fund the Commitments of any Initial or Joining Investor or to transfer and contribute the Rollover Commitment by the Rollover Investor is granted under Section 8.5 of the Merger Agreement as contemplated by Section 2.5.1 hereof, the Majority Holder may, among other things, terminate, pursuant to Section 5.3, the participation in the transaction of (i) any Initial or Joining Investor that does not fund its Commitment or that asserts its unwillingness to fund its Commitment, in each case, as required by its Closing Equity Commitment Letter and (ii) the Rollover Investor if it does not transfer or contribute its Rollover Commitment or if it asserts its unwillingness to transfer or contribute its Rollover Commitment, in each case, as required by its Rollover Agreement; provided that such termination shall not affect the other Investors’ or Parent’s rights against such Failing Investor (as defined herein) with respect to such failure to fund or such Failing Investor’s continuing obligations hereunder as set forth in (x) Sections 2.5, 2.9 and 5 (other than Section 5.10) hereof and (y) such Failing Investor’s Equity Commitment Letters.

2.4 Debt Financing and Voting Agreement.

2.4.1 Subject to consulting with the other Consortium Investors, the Majority Holder may cause Parent and/or any holding company or Subsidiary of Parent, including Merger Sub and, at and after the Closing, the Company and its Subsidiaries, to (a) negotiate, enter into and borrow under definitive agreements relating to debt financing to be provided at the Closing and (b) arrange for, market and negotiate and enter into definitive agreements relating to high yield debt, including agreeing to the financial terms of such debt, to be issued at the Closing, in each such case, on terms and conditions consistent in all material respects with those set forth in the Debt Financing Commitments (including the flex provisions therein) and/or on such additional, modified or other terms as the Majority Holder shall approve; provided, that such additional, modified or other terms shall not be materially adverse to the Investors as compared to the terms of the Debt Commitment Letter; provided further that, for the avoidance of doubt, any such debt financing shall be non-recourse to the Investors.

2.4.2 Subject to consulting with the other Consortium Investors, the Majority Holder may cause Parent to take or refrain from taking any action with respect to the Voting Agreement, dated as of the date hereof, by and among the Rollover Investor, Parent and the Company (the “Voting Agreement”). The Rollover Investor agrees that until the Merger Agreement is terminated in accordance with its terms, the Rollover Investor will cause all “Owned Shares” (as defined in the Voting Agreement) to be voted in favor of approval and adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger and against any other action, proposal, agreement or transaction made in opposition to or competition with the Merger or the Merger Agreement.

2.5 Equity Commitments.

2.5.1 Each of the Investors hereby affirms and agrees that it is bound by its Commitment or Rollover Commitment, as applicable, and the provisions set forth in each of its Equity Commitment Letters or Rollover Agreement, as applicable, and that Parent shall be entitled to enforce the provisions of each Equity Commitment Letter or Rollover Agreement, as applicable, upon the direction of (a) the Majority Holder (provided that the Majority Holder has delivered a written notice to each other Investor stating that the Majority Holder will fund its or their Commitment immediately prior to the consummation of the Merger and concurrently with the funding of the Commitments of the other Initial and Joining Investors and the transfer and contribution of the Rollover Commitment by the Rollover Investor) or (b) the Company if the Company is permitted to enforce, or to cause Parent to enforce, the provisions of the Equity Commitment Letters and Rollover Agreement, as applicable, under the specific circumstances and as specifically set forth therein and in Section 8.5 of the Merger Agreement and does in fact so enforce, or cause Parent to enforce, such provisions. To the extent Parent enforces any Equity Commitment Letter or Rollover Agreement, as applicable, at the direction of the Majority Holder, Parent shall not attempt to enforce any Closing Equity Commitment Letter or Rollover Agreement, as applicable, until the Closing Conditions have been satisfied or validly waived as permitted hereunder. The Equity Commitment Letters shall only be funded by each Initial and Joining Investor ratably and substantially contemporaneously with each of the other Initial and Joining Investors and with the Rollover Commitment under the Rollover Agreement, the Rollover Shares shall only be transferred and contributed to Parent substantially contemporaneously with the Initial and Joining Investors funding under their Commitments, and Parent shall only enforce the Equity Commitment Letters and Rollover Agreement ratably among the Investors. Parent shall not have any right to enforce an Equity Commitment Letter or Rollover Agreement, as applicable, unless acting at the direction of the Majority Holder or the Company as set forth above, and no Investor shall have any right to enforce any of the Equity Commitment Letters or

the Rollover Agreement other than (x) an Investor shall have the right to enforce any Equity Commitment Letter or Rollover Agreement to which it is a party and (y) as set forth in the last sentence of Section 5.3.2.

2.5.2 Prior to the Closing and the contribution of the equity funding contemplated by each Equity Commitment Letter and the Rollover Investment contemplated by the Rollover Agreement, BCP (or an Affiliate thereof) shall be the shareholder and appoint the members of the board of directors of Parent or any of its holding companies or Subsidiaries, including Merger Sub.

2.5.3 Except in the case of and to the extent of any syndication, all equity interests issued by Parent in connection with the Equity Commitment Letters or Rollover Agreement, as the case may be, at the Closing shall be issued to the Investors and their respective Permitted Transferees pro rata in class, series and amount and otherwise in accordance with such Investors’ Commitments or Rollover Commitment, as the case may be, and each Consortium Investor shall purchase (or acquire through rollover in the case of the Rollover Investor) equity interests (or debt instruments or securities) of each class and series at the same price per share (or other applicable unit).

2.6 Company Termination Fee. Any Company Termination Fee paid by the Company or any of its Affiliates to Parent or its designee pursuant to the Merger Agreement shall be promptly paid by Parent or its designee to the Initial Investors or their designees (other than with respect to a Failing Investor at the time of termination of the Merger Agreement) pro rata in proportion to their respective Commitments. A Non-Consenting Investor whose participation in the transaction has been terminated as provided in Section 2.2 shall not share in any portion of the Company Termination Fee. For the avoidance of doubt, when calculating the pro rata amount of any Company Termination Fee due to BCP or its designee, such calculation shall be made, unless otherwise determined by BCP, without giving effect to any syndications.

2.7 Notices. Each of Parent and BCP shall use its reasonable best efforts to keep the other Investors reasonably apprised of the status of matters relating to the transactions contemplated by the Merger Agreement and will use their reasonable best efforts to provide the other Investors with at least five (5) business days prior written notice of the Closing under the Merger Agreement. Any notices or correspondence received by Parent pursuant to the Merger Agreement shall be promptly provided to each Investor.

2.8 No Transfers. Prior to Closing, BCP shall not transfer any equity interests it holds in any common acquisition vehicle formed or used in connection with the transactions contemplated by this Agreement (including Parent) and, without the consent of the Majority Holder, no Investor shall transfer its obligations and rights under its Equity Commitment Letters other than (x) by BCP pursuant to any syndications or (y) to its Permitted Transferees.

2.9 Exclusivity.

2.9.1 Other than in connection with a syndication or potential syndication, no Investor shall, and each Investor shall cause its Affiliates not to, directly or indirectly (whether alone or jointly with one or more persons), engage in negotiations or discussions with any person, solicit or entertain proposals from any person, submit any indication of interest or bid to any person, or provide to any person information, in each case, other than with or to the Investors, their Affiliates and respective employees, advisors and representatives, regarding any transaction that entails the acquisition of all or substantially all of the assets or equity interests of the Company or an intended objective of which is to impede the acquisition of the Company (a “Competing

Transaction”), nor shall any Investor or any of such Investor’s Affiliates otherwise be involved with any Competing Transaction (whether as investor, lender, advisor or in any other capacity), except in each case, (x) in connection with this Agreement, (y) except with respect to the Majority Holder or its Affiliates, with the prior written consent of the Majority Holder or (z) in such Investor’s capacity or their Affiliates’ capacities as passive limited partners or passive investors in third party managed funds or vehicles. The forgoing restriction shall apply (including with respect to any Failing Investor) until seven days after this Agreement is terminated pursuant to Section 1.1.

2.9.2 Notwithstanding the foregoing provisions of Section 2.9.1 or anything to the contrary contained herein, nothing in this letter agreement shall limit the ordinary course activities of the Affiliates of GIC or Caisse (including brokerage, investment, financial, merger or other advisory, financing, asset management, trading, market making, arbitrage, and investment activities conducted in the ordinary course of business but, other than in the case of an Investor’s Affiliates or investment divisions that are primarily engaged in public market investments, it being understood and agreed that participating in any transaction involving the acquisition of the Company other than by Parent shall not be considered ordinary course activities); provided that such activities are conducted in compliance with standard practices and procedures (including those known as “Chinese Walls”) restricting the flow of information between such Affiliate’s personnel who have access to confidential information with respect to the transactions contemplated herein and other personnel of such Affiliate.

2.10 Regulatory Matters. Each Investor will use reasonable best efforts to supply and provide information that is accurate in all material respects to any Governmental Entity requesting such information in connection with filings or notifications under, or relating to, any applicable laws or regulatory requirements or other regulatory matters; provided that, to the extent in accordance with the Merger Agreement: (i) confidential information of an Investor or its Affiliates may be provided on a counsel-only basis or directly to the applicable Governmental Entity requesting such information and (ii) to the extent permitted by applicable law, all appearances, submissions, presentations, briefs and proposals made or submitted by or on behalf of any Investor before any Governmental Entity shall be controlled by the Investor making or submitting such appearance, submission, presentation, brief or proposal, as applicable. Notwithstanding anything to the contrary in this Agreement, no Investor shall, whether prior to or following Closing, be required to cause any portfolio company, investment fund or other Affiliate of any Investor or any fund managed or advised by the same person as any such fund or any Affiliate thereof or any director, officer, employee, general partner, limited partner, member or manager of any of the foregoing to take any action, undertake any divestiture or restrict its conduct other than to provide responsive information required to make any submission or application to a Governmental Entity and to otherwise cooperate in connection with any such submission or application as is necessary and customary under the circumstances.

Each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any Delaware state or federal court within the State of Delaware), in the event any dispute arises out of this Agreement or any of the transactions contemplated by this Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (c) agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the courts of the State of Delaware, as described above.

5.8 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

5.9 Exercise of Rights and Remedies. No delay of or omission in the exercise of any right, power or remedy to any party as a result of any breach or default by any other party under this Agreement

shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any such delay, omission nor waiver of any single breach or default be deemed a waiver of any other breach occurring before or after that waiver.

5.10 Cooperation; Consultation. Subject to the express provisions of this Agreement, the Consortium Investors will use their reasonable best efforts to cooperate with each other in connection with the Merger and all other significant matters in connection therewith and the other matters contemplated hereby and (with respect to the Initial Investors) the debt financing for the Merger.

5.11 Litigation. Subject to the immediately following sentence and subject to consulting with the other Initial Investors, the Majority Holder shall be entitled to manage, prosecute, defend, compromise and/or settle any litigation or other action before any governmental authority or arbitrator (provided that each other Investor shall be entitled to participate in any such litigation or other action and to retain its own counsel) (i) brought against Parent, Merger Sub and/or any of the Investors by the Company or its Affiliates or any of the Company’s shareholders or (ii) brought by or against Parent, Merger Sub and/or any of the Investors by or against any debt financing sources for the Merger or their affiliates; provided that the Majority Holder shall not settle any such litigation or other action or take any material actions with respect to the foregoing without the consent of each of the Investors that is party thereto (such consent not to be unreasonably withheld, delayed or conditioned); provided further, that any Investor party to any such litigation or other action may settle any such litigation or action solely as to itself so long as such settlement (i) does not involve non-monetary damages or adverse admissions, (ii) results in a complete dismissal from any claims against such Investor in such litigation or action and (iii) does not prejudice the other Investors or Parent with respect to such litigation or action or any related litigation or action. Notwithstanding anything to the contrary contained in this Agreement, each Investor shall have the exclusive right to manage, prosecute, defend, compromise and/or settle, in its sole discretion, any litigation or other action before any governmental authority or arbitrator brought solely against such Investor by the Company or any of its shareholders or Affiliates that does not relate to matters the subject of any other pending or threatened litigation, arbitration or other action involving Parent, Merger Sub and/or the other Investors.

5.12 Entire Agreement; Assignment. This Agreement, together with the agreements and other documents referenced herein, constitutes the entire agreement, and supersedes all prior agreements, understandings, negotiations and statements, both written and oral, among the parties or any of their affiliates with respect to the subject matter contained herein, except for such other agreements as are referenced herein and any existing confidentiality agreements entered into by any Investor or its Affiliates in connection with the transactions contemplated hereby which shall, in each case, continue in full force and effect in accordance with their terms. Other than as expressly provided herein or pursuant to any syndication, this Agreement shall not be assignable by any party hereto by operation of law or otherwise, without the prior written consent of the Initial Investors; provided that each of the Initial Investors may assign this Agreement to the ultimate parent of such Investor or any controlled affiliate of such parent.

5.13 Counterparts. This Agreement may be executed in any number of counterparts (including by telecopy and electronic imaging scans), each of which when executed and delivered shall be an original, but all of which when taken together shall constitute a single instrument.
