8.2 Indemnification. To the fullest extent permitted by law, the Company shall indemnify and hold harmless each Covered Person from and against any and all losses, claims, demands, liabilities, expenses, judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (“Claims”), in which the Covered Person may be involved, or threatened to be involved, as a party or otherwise, by reason of its management of the affairs of the Company or which relates to or arises out of the Company or its property, business or affairs. A Covered Person shall not be entitled to indemnification under this Section 8.2 with respect to (i) any Claim with respect to which such Covered Person has engaged in fraud, willful misconduct, bad faith or gross negligence or (ii) any Claim initiated by such Covered Person unless such Claim (or part thereof) (A) was brought to enforce such Covered Person’s rights to indemnification hereunder or (B) was authorized or consented to by the Member. Expenses incurred by a Covered Person in defending any Claim shall be paid by the Company in advance of the final disposition of such Claim upon receipt by the Company of an undertaking by or on behalf of such Covered Person to repay such amount if it shall be ultimately determined that such Covered Person is not entitled to be indemnified by the Company as authorized by this Section 8.2.

8.3 Amendments. Any repeal or modification of this Article 8 by the Member shall not adversely affect any rights of such Covered Person pursuant to this Article 8, including the right to indemnification and to the advancement of expenses of a Covered Person existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

8.4 Predecessors. To the fullest extent permitted by the Delaware General Corporation Law (the “DGCL”) as it presently exists or may hereafter be amended, any director of the predecessor entity to the Company (the “Predecessor”) shall not be personally liable to the Company, the Member or the Predecessor’s stockholders for monetary damages for breach of fiduciary duty as a director. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Predecessor shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

The Company shall indemnify and hold harmless, to the fullest extent permitted by the DGCL as it presently exists or may hereafter be amended, any director or officer of the Predecessor who was or is made or is threatened to be made a party or is otherwise involved in any Claim by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director, officer, employee or agent of the Predecessor or is or was serving at the request of the Predecessor as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such Claim. The Company shall be required to indemnify a person in connection with a Claim initiated by such person only if the Claim was authorized by the Predecessor’s Board of Directors.

The Company shall have the power to indemnify and hold harmless, to the extent permitted by applicable law as it presently exists or may hereafter be amended, any employee or agent of the Predecessor who was or is made or is threatened to be made a party or is otherwise involved in any Claim by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was an employee or agent of the Predecessor or is or was serving at the request of the Predecessor as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such Claim.

8.5 Prepayment of Expenses. The Company shall pay the expenses incurred by any Covered Person or any officer or director of the Predecessor, and may pay the expenses incurred by any employee or agent of the Company or the Predecessor, in defending any Claim in advance of its final disposition; provided, however, that the payment of expenses incurred by a person in advance of the final disposition of the Claim shall be made only upon receipt of an undertaking by the person to repay all amounts advanced if it should be ultimately determined that the person is not entitled to be indemnified under this Article 8 or otherwise.

8.6 Determination: Claim. If a claim for indemnification or payment of expenses under this Article 8 is not paid in full within sixty days after a written claim therefor has been received by the Company the claimant may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Company shall have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under this Agreement or applicable law.

8.7 Non-Exclusivity of Rights. The rights conferred on any person by this Article 8 shall not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of this Agreement, agreement, action of the Member or the Board of Directors of the Predecessor or otherwise.

8.8 Insurance. The Company may purchase and maintain insurance on behalf of any Covered Person or any person who is or was a director, officer, employee or agent of the Predecessor, or is or was serving at the request of the Company or the Predecessor as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Company would have the power to indemnify him or her against such liability under the provisions of the DGCL.

ARTICLE 9

Miscellaneous

9.1 Tax Treatment. Unless otherwise determined by the Member, the Company shall be a disregarded entity for U.S. federal income tax purposes (as well as for any analogous state or local tax purposes), and the Member and the Company shall timely make any and all necessary elections and filings for the Company to be treated as a disregarded entity for U.S. federal income tax purposes (as well as for any analogous state or local tax purposes).

9.2 Amendments. Amendments to this Agreement and to the Certificate of Formation shall be approved in writing by the Member. An amendment shall become effective as of the date specified in the approval of the Member or if none is specified as of the date of such approval or as otherwise provided in the Act.

9.3 Severability. If any provision of this Agreement is held to be invalid or unenforceable for any reason, such provision shall be ineffective to the extent of such invalidity or unenforceability, provided, however, that the remaining provisions will continue in full force without being impaired or invalidated in any way unless such invalid or unenforceable provision or clause shall be so significant as to materially affect the expectations of the Member regarding this Agreement. Otherwise, any invalid or unenforceable provision shall be replaced by the Member with a valid provision which, in the good faith belief of the Member, most closely approximates the intent and economic effect of the invalid or unenforceable provision.
