PURCHASER’S REPRESENTATIONS AND WARRANTIES

The Purchaser (and, if applicable, each Co-Investor) represents and warrants to each Seller, severally and not jointly, as of the date hereof (or, in the case of an applicable Co-Investor, the date of such Co-Investor’s Joinder) and as of the Closing, that:

Section 3.1 No Sale or Distribution. Such Person is acquiring the Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act.

Section 3.2 Accredited Investor Status. Such Person is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act (“Regulation D”).

Section 3.3 Reliance on Exemptions. Such Person understands that the Shares are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Seller is relying in part upon the truth and accuracy of, and such Person’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Person set forth herein in order to determine the availability of such exemptions and the eligibility of such Person to acquire the Shares.

Section 3.4 Information. Such Person has not relied on the Seller, EQT AB (“EQT”), EQT Fund Management S.à.r.l. (“EFMS”) (together, EQT and EFMS are the “Fund Managers”), any other funds and accounts managed by the Fund Managers, any other Affiliates of the Fund Managers or the Seller or any of their respective current or former partners, shareholders, members, managers, officers, directors, employees, representatives and agents of any of the foregoing (collectively, the “Seller Persons”) with respect to any legal, accounting or tax matters relating to the purchase of the Shares. Such Person has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Shares. Such Person has, independently and without reliance on the Seller or any other Seller Person, and based on such information concerning the sale of the Shares and the Company as such Person deemed appropriate, reliable and adequate, made its own investment analysis and decision to consummate the acquisition of the Shares. Such Person understands that its investment in the Shares involves a high degree of risk and is able to afford a complete loss of such investment and such Person believes that, by reason of its business and financial experience, it is capable of evaluating the merits and risks of the acquisition of the Shares and of protecting its own interests in connection with such acquisition.

6

Section 3.13 Financing.

(a) In the case of a Co-Investor only, (i) such Co-Investor, as applicable, has available to it as of the date of its respective Joinder, and will have available to it at the Closing and at all times prior to the Closing, uncalled capital commitments or other readily available funds sufficient to enable such Co-Investor to satisfy all of its obligations under this Agreement, including the payment of its applicable portion of the Purchase Price, and any costs, fees and expense of, or payable by, such Co-Investor, and (ii) such Co-Investor’s obligations under this Agreement to effect the Purchase and Sale and consummate the Closing or any of the other transactions contemplated hereby, are not subject to, or conditioned on, the receipt or availability of any funds or financing.

(b) In the case of the Purchaser only: The Purchaser’s obligations under this Agreement to effect the Purchase and Sale and consummate the Closing or any of the other transactions contemplated hereby, are not subject to, or conditioned on, the receipt or availability of any funds or financing. The Purchaser has furnished the Seller with a true, correct and complete copy of the Equity Commitment Letter, pursuant to which the Funds have committed to invest, subject to the terms and conditions thereof, cash in the aggregate amount set forth therein for the purposes of funding the transactions contemplated by this Agreement (the “Equity Financing”). The Equity Commitment Letter has not been amended, supplemented or modified, and no provision thereof has been waived, prior to the date hereof, no such amendment, restatement, supplement, modification or waiver is contemplated or pending as of the date hereof, and the respective commitments contained in the Equity Commitment Letter have not been withdrawn, terminated or rescinded in any respect, and no such withdrawal, termination or rescission is contemplated as of the date hereof. As of the date hereof, the Purchaser nor, to the knowledge of the Purchaser, any other counterparty thereto has committed any breach of any of its representations, warranties, covenants or other obligations set forth in, or is in default under, the Equity Commitment Letter, and to the Purchaser’s knowledge as of the date hereof, no event has occurred or circumstance exists that, with or without notice, lapse of time or both, would or would reasonably be expected to (i) constitute or result in a breach or default on the part of any Person under the Equity Commitment Letter, (ii) constitute or result in a failure to satisfy a condition precedent or other contingency set forth in any of the Equity Commitment Letter, (iii) make any of the assumptions or any of the statements set forth in the Equity Commitment Letter inaccurate or (iv) otherwise result in any portion of the Equity Financing not being available. There are no side letters or other contracts, arrangements or understandings, whether written or oral, related to the Equity Financing other than as expressly set forth in the Equity Commitment Letter furnished to the Seller. The aggregate proceeds contemplated to be provided under the Equity Commitment Letter will be sufficient when funded for the Purchaser to pay and satisfy in full the obligations pursuant to this Agreement to pay the Purchase Price payable at Closing in connection with the transactions contemplated by this Agreement. The Equity Commitment Letter is not subject to any conditions or other similar contingencies other than as expressly set forth therein and is in full force and effect and is a legal, valid, binding and enforceable obligation of the Purchaser and each of the other parties thereto. As of the date hereof, the Purchaser (A) has no reasonable basis to believe it will not be able to satisfy on a timely basis each term and condition relating to the closing or funding of the Equity Financing, (B) knows of no fact, occurrence, circumstance or condition that would reasonably be expected to (1) cause the Equity Commitment Letter to terminate, to be withdrawn, modified, repudiated or rescinded or to be or become ineffective, (2) cause any of the terms or conditions relating to the closing or funding of any portion of the Equity Financing not to be met or complied with, or (3) otherwise cause the full amount (or any portion) of the funds contemplated to be available under the Equity Commitment Letter to not be available to the Purchaser on a timely basis (and in any event as of

9

the Closing Date); and (C) knows of no potential impediment to the funding of any of the payment obligations of the Purchaser under this Agreement. Assuming the conditions set forth in Section 1.4 and Section 1.6 are satisfied at Closing, as of the date hereof, the Purchaser has no reason to believe that any of the conditions to the Equity Financing will not be satisfied or the full amount of the Equity Financing will not be available to the Purchaser on the Closing Date, and, as of the date hereof, the Purchaser is not aware of the existence of any fact or event as of the date hereof that would reasonably be expected to cause such conditions to the Equity Financing not to be satisfied or the full amount of the Equity Financing not to be available.

Section 3.14 Limited Guaranty. In the case of the Purchaser only, concurrently with the execution of this Agreement, the Purchaser has delivered to the Seller the duly executed Limited Guaranty of the Funds guaranteeing the Purchaser’s payment obligations in respect of monetary damages.

Section 3.15 No Additional Seller Representations. Such Person acknowledges and agrees that none of the Seller nor any Seller Persons has made and none of them does make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement and none of the Seller nor any Seller Persons has any obligations to such Person, whether express or implied, including fiduciary obligations, with respect to the transactions contemplated hereby.

The equitable remedies described in this Section 5.11 shall be in addition to, and not in lieu of, any other remedies at law or in equity that the Parties to this Agreement may elect to pursue.

Section 5.12 No Recourse. This Agreement may only be enforced against, and any suit, action or proceeding that may be based upon or under, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against the entities that are expressly identified as Parties hereto and then only with respect to the specific obligations set forth herein with respect to such Party. No former, current or future general or limited partners, stockholders, equityholders, members, managers, directors, officers, employees, agents or Affiliates of any Party or any former, current or future general or limited partner, stockholder, equityholder, member, manager, director, officer, employee, agent or Affiliate of any of the foregoing (“No Recourse Parties”) shall have any liability for any obligations or liabilities of any Party under this Agreement or for any suit, action or proceeding (whether at law, in equity in tort, in contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any oral representations made or alleged to be made in connection herewith. In no event shall any Party, and the Parties shall cause their respective No Recourse Parties not to, seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any No Recourse Party (other than a Party to the extent set forth in this Agreement). Notwithstanding the forgoing or anything else in this Agreement, this Section 5.12 shall not apply to, and shall in no way limit the rights of the Seller under the Equity Commitment Letter or Limited Guaranty.

Section 5.13 Purchaser’s Obligations. For the avoidance of doubt, to the extent that any Co-Investor pursuant to and in accordance with the terms and conditions of this Agreement becomes a party to this Agreement, the Purchaser shall remain and shall be responsible and liable for any and all obligations hereunder assumed by such Co-Investor. The Purchaser hereby agrees that a failure by any Co-Investor to perform any of its obligations hereunder shall not in any way delay or affect the consummation of the transactions contemplated by this Agreement or the payment by the Purchaser of the Purchase Price when required pursuant to Section 1.2 and Section 1.3, and the Purchaser hereby guarantees and shall perform any and all such obligations.
