INDEMNIFICATION PROCEDURES. (a) Whenever any Indemnitee shall have actual knowledge of the reasonable likelihood of the assertion of a Claim, NCP (acting on its own behalf or, if requested by any such Indemnitee other than itself, on behalf of such Indemnitee) or such Indemnitee shall notify the Company and the Parent in writing of the Claim (the "NOTICE OF CLAIM") with reasonable promptness after such Indemnitee has such knowledge relating to such Claim and has notified NCP thereof. The Notice of Claim shall specify all material facts known to NCP (or if given by such Indemnitee, such Indemnitee) that may give rise to such Claim and the monetary amount or an estimate of the monetary amount of the Obligation involved if NCP (or if given by such Indemnitee, such Indemnitee) has knowledge of such amount or a 6 reasonable basis for making such an estimate. The failure of NCP to give such Notice of Claim shall not relieve either the Company or the Parent of its indemnification obligations under this Agreement except to the extent that such omission results in a failure of actual notice to it and it is materially injured as a result of the failure to give such Notice of Claim. The Company and the Parent shall, at their expense, undertake the defense of such Claim with attorneys, of their own choosing satisfactory in all respects to NCP. NCP may participate in such defense with counsel of NCP's choosing at the expense of the Company and the Parent. In the event that the Company or the Parent do not undertake the defense of the Claim within a reasonable time after NCP has given the Notice of Claim, NCP may, at the expense of the Company and the Parent and after giving notice to the Company and the Parent of such action, undertake the defense of the Claim and compromise or settle the Claim, all for the account of and at the risk of the Company and the Parent. In the defense of any Claim, the Company and the Parent shall not, except with the consent of NCP, consent to entry of any judgment or enter into any settlement that includes any injunctive or other non-monetary relief, or that does not include as an unconditional term thereof the giving by the person or persons asserting such Claim to such Indemnitee of a release from all liability with respect to such Claim. In each case, NCP and each other Indemnitee seeking indemnification hereunder will cooperate with the Company and the Parent, so long as the Company and the Parent are conducting the defense of the Claim, in the preparation for and the prosecution of the defense of such Claim, including making available evidence within the control of NCP or such Indemnitee, as the case may be, and persons needed as witnesses who are employed by NCP or such Indemnitee, as the case may be, in each case as reasonably needed for such defense and at cost, which cost, to the extent reasonably incurred, shall be paid by the Company and the Parent. (b) The Company and the Parent hereby agree to advance costs and expenses, including attorney's fees, incurred by NCP (acting on its own behalf or, if requested by any such Indemnitee other than itself, on behalf of such Indemnitee) or any Indemnitee in defending any Claim in advance of the final disposition of such Claim upon receipt of an undertaking by or on behalf of NCP or such Indemnitee to repay amounts so advanced if it shall ultimately be determined that NCP or such Indemnitee is not entitled to be indemnified by the Company and the Parent as authorized by this Agreement. 7 (c) NCP shall notify the Company and the Parent in writing of the amount of any Claim actually paid by NCP (the "NOTICE OF PAYMENT"). The amount of any Claim actually paid by NCP shall bear simple interest at the rate equal to the Bank of Nova Scotia's prime rate as of the date of such payment plus 2% per annum, from the date the Company and the Parent receive the Notice of Payment to the date on which the Company or the Parent shall repay the amount of such Claim plus interest thereon to NCP. 7. CERTAIN COVENANTS. The rights of each Indemnitee to be indemnified under any other agreement, document, certificate or instrument or applicable law are independent of and in addition to any rights of such Indemnitee to be indemnified under this Agreement. The rights of each Indemnitee and the obligations of the Company and the Parent hereunder shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnitee. The Company and the Parent shall maintain the State of Delaware as their state of incorporation and shall implement and maintain in full force and effect any and all corporate charter and by-law provisions that may be necessary or appropriate to enable it to carry out their obligations hereunder to the fullest extent permitted by Delaware corporate law, including without limitation a provision of their certificates of incorporation eliminating liability of a director for breach of fiduciary duty to the fullest extent permitted by Section 102(b)(7) (or any successor section thereto) of the General Corporation Law of the State of Delaware, as it may be amended from time to time. 8. GOVERNING LAW. This Agreement shall be governed in all respects, including validity, interpretation and effect, by the law of the State of New York, regardless of the law that might be applied under principles of conflict of laws, except to the extent that the corporate law of the State of Delaware specifically and mandatorily applies, in which case such law shall apply. 9. SEVERABILITY. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby. 10. INDEPENDENT CONTRACTOR STATUS.
