The Series B Notes (i) are to be issued pursuant to an Indenture, dated as of December 19, 2011 (the “Existing Indenture”), as amended by the First Supplemental Indenture (“Supplemental Indenture No. 1”) (the Existing Indenture, as so amended, the “Amended Indenture”), to be dated of even date herewith, in each case, entered into among the Company, the Guarantors (as defined below) party thereto and U.S. Bank National Association, a national banking association, as trustee and collateral agent (in such capacity, the “Trustee”).

(ll) After giving effect to the Transactions, other than ▇▇▇▇▇ granted pursuant to the Transaction Documents and Permitted Liens, none of the Company or the Guarantors have pledged, assigned, sold or granted a security interest in the Collateral. After giving effect to the Transactions, no security agreement, financing statement, equivalent security or Lien instrument or continuation statement authorized by the Company or any Guarantor and listing the Company or any Guarantor as debtor covering all or any part of the Collateral shall be on file or of record in any jurisdiction, except in respect of Permitted Liens or such as may have been filed, recorded or made as contemplated by the Transaction Documents.

(mm) The historical financial statements (including the related notes and supporting schedules) included in or incorporated by reference into the Disclosure Package present fairly in all material respects the financial condition, results of operations and cash flows of the entities purported to be shown thereby, at the dates and for the periods indicated, and have been prepared in conformity with accounting principles generally accepted in the United States applied on a consistent basis throughout the periods involved.

(nn) The Company, the Guarantors and their respective subsidiaries have filed all necessary federal, state and material foreign income and material franchise tax returns required to be filed prior to the date hereof (taking into account extensions requested in good faith by the Company and in compliance with applicable tax rules and regulations) and paid all taxes shown as due thereon; all such tax returns are complete and correct in all material respects; all material tax liabilities are adequately provided for on the books of the Company, the Guarantors and their respective subsidiaries; and the Company and the Guarantors have no knowledge of any tax proceeding or action pending or threatened against the Company, the Guarantors or any of their respective subsidiaries that, individually or in the aggregate, might have a Purchase Agreement Material Adverse Effect.

loss, claim, damage, liability or action arises out of, or is based upon, (i) any breach by the Company or the Guarantors of any representation or warranty or material failure to comply with any of the covenants and agreements contained in this Agreement, (ii) any untrue statement or alleged untrue statement of a material fact contained (A) in the Disclosure Package or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company or the Guarantors (or based upon any written information furnished by the Company or the Guarantors) specifically for the purpose of qualifying any or all of the Securities under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), (iii) the omission or alleged omission to state in the Disclosure Package, or in any amendment or supplement thereto, in any Blue Sky Application, any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iv) the Transactions (other than those contemplated by this Agreement) and shall reimburse the Purchasers and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Purchasers or any such affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability that the Company and the Guarantors may otherwise have to the Purchasers or to any affiliate, director, officer, employee or controlling person of any of the Purchasers.

(b) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 7 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Purchasers shall have the right to employ counsel to represent jointly the Purchasers and their directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Purchasers against any of the Company or the Guarantors under this Section 7, if (i) the Company, the Guarantors, the Purchasers shall have so mutually agreed; (ii) the Company and the Guarantors have failed within a reasonable time to retain counsel reasonably satisfactory to the Purchasers; (iii) any of the Purchasers and their respective directors, managers, officers, employees and controlling persons shall have reasonably concluded, based on the advice of

counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Company or the Guarantors; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Purchasers or their directors, officers, employees or controlling persons, on the one hand, and the Company or the Guarantors, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Company and the Guarantors. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(c) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as shall be appropriate to reflect the relative fault of the Company and the Guarantors, on the one hand, and the Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors, or the Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantors, the Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 7(c) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7 shall be deemed to include, for purposes of this Section 7 any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.
