5

by a final non-appealable ruling of a court of competent jurisdiction. In any action, suit or proceeding against any Indemnitee relating to or arising out of, or alleged to relate to or to arise out of, any such action or non-action, the Indemnitee shall have the right jointly to employ, at the expense of the Company, counsel of the Indemnitee’s choice, which counsel shall be reasonably satisfactory to the Company, in such action, suit or proceeding. The indemnification rights contained in this Agreement shall be cumulative and in addition to any and all other rights, remedies and recourse to which an Indemnitee, its heirs, successors, assignees and administrators are entitled. The indemnification provided in this Agreement will inure to the benefit of the heirs, successors, assignees and administrators of each of the Indemnitees. If the indemnification provided for above is unavailable in respect of any Losses, then, in lieu of indemnifying an Indemnitee, the Company agrees to contribute to the amount paid or payable by such Indemnitee in such proportion as is appropriate to reflect the relative fault of the Company on the one hand, and such Indemnitee, on the other hand, in connection with the actions which resulted in such Losses, as well as any other equitable considerations.

9.Disclaimer; Limitation of Liability.

(a)The Service Provider makes no representations or warranties, express or implied, in respect of any of the Services to be rendered by it hereunder. In no event shall any Indemnitee be liable to any member of the Company Group for any act, alleged act, omission or alleged omission that does not constitute fraud or willful misconduct of such Indemnitee as determined by a final, non-appealable determination of a court of competent jurisdiction.

(b)In no event will any Indemnitee be liable to any member of the Company Group or to any of their respective officers, directors, employees or agents for any indirect, special, incidental, punitive or consequential damages, including, without limitation, lost profits or savings, whether or not such damages are foreseeable, or for any third-party claims (whether based in contract, tort or otherwise), relating to the Services to be provided hereunder.

(c)Each Indemnitee shall have the right to (23) engage or invest in the same or similar business activities or lines of business as any member of the Company Group and (23) conduct business with any client or customer of any member of the Company Group. No Indemnitee shall be liable to any member of the Company Group for breach of any duty (contractual or otherwise) by reason of any such activities.

(d)In the event that any Indemnitee acquires knowledge of a potential transaction or matter that may be a corporate opportunity for any member of the Company Group on the one hand, and any Indemnitee, (or another Person, including without limitation, any member of the PSPIB Group, any Affiliate of the Service Provider, any other client of the Indemnitee or investment made by such person or client), on the other hand, no Indemnitee shall have any duty (contractual or otherwise) to communicate or present such corporate opportunity to any member of the Company Group and, notwithstanding any provision hereunder, no Indemnitee shall be liable to any member of the Company Group for breach of any duty (contractual or otherwise) by reason of the fact that any Indemnitee directly or indirectly pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to any member of the Company Group.
