However, this Agreement shall not impose any obligation on the Indemnitee or the Company to continue the Indemnitee’s service to the Company beyond any period otherwise required by law or by other agreements or commitments of the parties, if any.

3. Agreement to Indemnify. Subject always to the provisions of this Agreement, the Articles and the Companies Law, the Company hereby agrees to hold harmless and indemnify the Indemnitee against all Expenses and Liabilities properly incurred or paid by the Indemnitee by reason of the Indemnitee’s Corporate Status to the fullest extent permitted by Article 77 of the Companies Law, as amended, and any other applicable law. In furtherance of the foregoing indemnification, and without limiting the generality thereof:

(a) Subject to the exceptions contained in Section 4, Section 6 and Section 8 below, if the Indemnitee was or is a party or is threatened to be made a party to or participant in any Proceeding (other than an action by or in the right of the Company) by reason of the Indemnitee’s Corporate Status, the Indemnitee shall be indemnified and held harmless by the Company against all Expenses and Liabilities properly incurred or paid by the Indemnitee or on the Indemnitee’s behalf in connection with such Proceeding (referred to herein as “Indemnifiable Expenses” and “Indemnifiable Liabilities,” respectively, and collectively as “Indemnifiable Amounts”).

(b) Subject to the exceptions contained in Section 4, Section 6 and Section 8 below, if the Indemnitee was or is, or is threatened to be made, a party to or participant in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of the Indemnitee’s Corporate Status, the Indemnitee shall be indemnified and held harmless by the Company against all Indemnifiable Expenses.

(d) [The Company hereby acknowledges that the Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by the Fund Indemnitors. Notwithstanding anything to the contrary herein, the Company hereby agrees that, subject always to the provisions of the Companies Law and the Articles (i) it is the indemnitor of first resort in respect of Indemnifiable Expenses properly incurred by the Indemnitee by reason of the Indemnitee’s Corporate Status (i.e., its obligations to the Indemnitee are primary and any obligation of the Fund Indemnitors to advance Expenses or to provide indemnification for the same Indemnifiable Amounts incurred by the Indemnitee are secondary), (ii) it shall be required to advance the full amount of Indemnifiable Expenses properly incurred by the Indemnitee by reason of the Indemnitee’s Corporate Status and shall be liable for the full amount of all Indemnifiable Amounts to the extent legally permitted and as required by the terms of this Agreement and/or the Articles (or any other agreement between the Company and the Indemnitee), without regard to any rights the Indemnitee may have against the Fund Indemnitors, and (iii) it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the

Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of the Indemnitee with respect to any claim for which the Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of the Indemnitee against the Company.]

4. Exceptions to Indemnification. The Indemnitee shall be entitled to indemnification under Section 3, provided, however, that the Company shall not indemnify or advance Expenses to Indemnitee with respect to any act, event or circumstance with respect to which it is prohibited to do so under applicable law (including the Companies Law) or the Articles. Further the indemnity in Section 3 shall not apply to any liability incurred by the Indemnitee (i) to the Company; (ii) to any Subsidiary; (iii) to pay a fine imposed in criminal proceedings or a sum payable to a regulatory authority by way of a penalty in respect of non-compliance with any requirement of a regulatory nature (however arising); (iv) in defending any criminal proceedings in which the Indemnitee is convicted; (v) in defending any civil proceedings brought by the Company, or a Subsidiary, in which judgment is given against the Indemnitee; (vi) in connection with any application pursuant to section 212 of the Companies Law (a “Relevant Application”) in which the court refuses to grant the Indemnitee relief; (vii) in the event that the liability incurred by the Indemnitee is, in the reasonable opinion of the Board, a result of fraud or wilful misconduct by the Indemnitee; (viii) in defending any proceedings brought by a regulatory authority in which a penalty is imposed on the Indemnitee; or (ix) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (a) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (b) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law and the Articles. The Company and the Indemnitee acknowledge and agree that nothing in this Section 4 shall preclude the Indemnitee from making claims against the Company to enforce the Indemnitee’s rights under this Agreement.

5. Procedure for Payment of Indemnifiable Amounts. The Indemnitee shall submit to the Company a written request specifying the Indemnifiable Amounts for which the Indemnitee seeks payment under Section 3 of this Agreement and a reasonable description of the basis for the claim, including therein or therewith such documentation and information as are reasonably available to the Indemnitee and necessary to establish that the Indemnitee is entitled to indemnification hereunder. Subject to the provisions of this Agreement, the Company shall pay such Indemnifiable Amounts to the Indemnitee within thirty (30) calendar days of receipt of the request.

successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall subject always to the provisions of the Companies Law and the Articles indemnify the Indemnitee against all Indemnifiable Amounts in connection with each successfully resolved claim, issue or matter. For purposes of this Agreement, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. Notwithstanding any of the foregoing, nothing in this Section 6 shall be construed to limit an Indemnitee’s right to indemnification which he or she would otherwise be entitled to pursuant to Section 3 hereof, regardless of the Indemnitee’s success in a Proceeding.

7. Effect of Certain Resolutions. Subject to the provisions of Section 11, neither the settlement or termination of any Proceeding nor the failure of the Company to award indemnification or to determine that indemnification is payable shall create an adverse presumption that the Indemnitee is not entitled to indemnification hereunder. In addition, subject to the provisions of Section 11, the termination of any Proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent shall not create a presumption that the Indemnitee did not act in good faith and in a manner which the Indemnitee reasonably believed to be in the best interests of the Company or, with respect to any criminal action or proceeding, had reasonable cause to believe that the Indemnitee’s action was unlawful.

8. Agreement to Advance Expenses; Conditions.

(a) Subject to the Companies Law and the provisions of this Agreement, the Company will fund all of the legal and other expenses (“Defence Costs”) properly incurred or to be properly incurred by the Indemnitee in defending any criminal or civil proceedings in connection with any alleged negligence, default, breach of duty or breach of trust by him in relation to the Company or in connection with any Relevant Application. Any request for funding under this Section 8 shall be made in writing by the Indemnitee to the Company and determined by resolution of the Board, subject to such conditions as the Board thinks fit.

(b) Any funding provided to the Indemnitee pursuant to this Section 8 shall be treated as a loan from the Company to the Indemnitee repayable on demand and otherwise on the terms set out in Section 8(c) and Section 8(d), together with such further terms as may be determined by the Board and the Indemnitee at the time that the arrangement is entered into.

(c) The terms are that if the Company provides funds to the Indemnitee in respect of Defence Costs arising in relation to criminal proceedings in which the Indemnitee is subsequently convicted or civil proceedings in which judgment is subsequently given against the Indemnitee or a Relevant Application in which the court subsequently refuses to grant the Indemnitee relief, then any obligation of the Company to make further contributions towards the Indemnitee’s Defence Costs shall cease and any amounts already advanced by the Company must be repaid not later than the date that the conviction, judgment or refusal to grant relief becomes final.

(d) In the event that the liability to which the loan relates can properly be discharged by way of indemnity in accordance with Section 3, the obligation to repay such loan will be discharged by way of indemnity in accordance with said Section 3. If the loan is not capable of being discharged by way of indemnity in accordance with the terms of this Agreement (or if the indemnity is insufficient to discharge the full amount of the loan because part of the loan cannot properly be discharged in that way), the loan (or the relevant part of it) shall be repayable by the Indemnitee on demand by the Company.

(e) For the purposes of this Section 8(c), a conviction, judgment or refusal of relief becomes final:

(i) if not appealed against, at the end of the period for bringing an appeal; or

(ii) if appealed against, at the time when the appeal (or any further appeal) is determined and the period for bringing any further appeal has ended or if the appeal is abandoned or otherwise ceases to have effect.

(f) The Indemnitee shall take all reasonable action to mitigate any loss suffered by him in respect of such Defence Costs.

9. Procedure for Advance Payment of Expenses. The Indemnitee shall submit to the Company a written request specifying the Indemnifiable Expenses for which the Indemnitee seeks an advancement under Section 8 of this Agreement. Subject to the terms of this Agreement, payment of Indemnifiable Expenses under Section 8 shall be made no later than thirty (30) calendar days after the Company’s approval of such request and on the terms set out in Section 8(b). At the request of the Company, the Indemnitee shall furnish such documentation and information as are reasonably available to the Indemnitee in connection with such advancement.

10. Remedies of Indemnitees.

(a) Right to Petition Court. In the event that the Indemnitee makes a request for payment of Indemnifiable Amounts under Section 3 and Section 5 herein or a request for an advancement of Indemnifiable Expenses under Sections 8 and Section 9 herein and the Company fails to make such payment or advancement in a timely manner pursuant to the terms of this Agreement, the Indemnitee may petition a court to enforce the Company’s obligations under this Agreement.

(b) Expenses. Subject always to the provisions of the Articles and the Companies Law, the Company agrees to reimburse the Indemnitee in full for any Expenses incurred by the Indemnitee in connection with investigating, preparing for, litigating, defending or settling any action brought by the Indemnitee under Section 10(a) above; provided, however, that if the Indemnitee is unsuccessful on the merits in such action, then the Company shall have no obligation to the Indemnitee under this Section 10(b).

the advancement of Indemnifiable Expenses under this Agreement shall not be a defence in any action brought under Section 10(a) above, and shall not create a presumption that such payment or advancement is not permissible.

11. Notice by Indemnitee. The Indemnitee agrees to notify the Company promptly upon being served with any summons, citation, subpoena, complaint, indictment, information, or other document relating to, or becoming aware of any circumstances which may lead to, any Proceeding which may result in the payment of Indemnifiable Amounts or the advancement of Indemnifiable Expenses hereunder; provided, however, that the failure to give any such notice shall not disqualify the Indemnitee from the right to receive payments of Indemnifiable Amounts or advancements of Indemnifiable Expenses unless and only to the extent that such failure or delay materially prejudices the Company.

(a) In addition, the Indemnitee shall:

(i) as soon as practicable, give written notice of such circumstances to the Company;

(ii) keep the Company informed of any developments in relation to such circumstances (including by promptly providing the Company with such information and copies of such documents as the Company may reasonably request) and consult the Company regarding the conduct of any claim arising in connection with such circumstances;

(iii) not make any admission of liability, agreement, settlement or compromise with any person in relation to any such circumstances without the prior written consent of the Company (such consent not to be unreasonably withheld or delayed);

(iv) allow the Company at any stage and at its sole discretion to take the sole conduct of and/or settle such actions the Company may deem appropriate in relation to any such circumstances and the Company shall be under no obligation in this respect to notify the Indemnitee of its decision so to settle such action(s); and

(v) take all reasonable action to mitigate any loss suffered by him in respect of such Indemnifiable Amounts or Indemnifiable Expenses.

(b) In the event that the Company makes any payment pursuant to this Agreement, the Company shall, save as set out in Section 3(d), be subrogated to the extent of such payment to all of the Indemnitee’s rights of recovery against third parties (including any claim under any applicable directors’ and officers’ insurance policy) in respect of the payment and the Indemnitee shall do everything that may be necessary to secure any rights including (but not restricted to):

(i) the execution of any documents necessary to enable the Company effectively to bring an action in the name of the Indemnitee; and

(ii) the provision of assistance as a witness.

(c) If the Company makes any payment to or for the benefit of the Indemnitee pursuant to this Agreement and the Indemnitee subsequently recovers or becomes entitled to recover from a third party any amount which is referable to any part of the liability for which payment was made by the Company, the Indemnitee shall immediately repay or procure the repayment to the Company of so much of the amount paid by the Company as does not exceed the amount recovered (or entitled to be recovered) by the Indemnitee, less any reasonable costs and expenses incurred by the Indemnitee in effecting any such recovery which are not recoverable from any third party.

(d) The Indemnitee shall not be entitled to recover more than once whether pursuant to this Agreement or otherwise in respect of any matter giving rise to a liability.

(e) Except as provided in Section 3(d) above, the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that the Indemnitee has otherwise actually received such payment under any insurance policy, contract agreement or otherwise.

13. Contract Rights Not Exclusive; Survival of Rights; Insurance.

(a) The rights to payment of Indemnifiable Amounts and advancement of Indemnifiable Expenses provided by this Agreement shall, subject always to the provisions of the Companies Law and the Articles be in addition to, but not exclusive of, any other rights which the Indemnitee may have at any time under applicable law, the Articles, or any other agreement, vote of shareholders or directors (or a committee of directors), or otherwise, both as to action in the Indemnitee’s official capacity and as to action in any other capacity as a result of the Indemnitee’s serving as a director of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of the Indemnitee under this Agreement in respect of any action taken or omitted by the Indemnitee in the Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in

equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

16. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement, or any clause thereof, shall be determined by a court of competent jurisdiction to be illegal, invalid or unenforceable, in whole or in part, such provision or clause shall be limited or modified in its application to the minimum extent necessary to make such provision or clause valid, legal and enforceable, and the remaining provisions and clauses of this Agreement shall remain fully enforceable and binding on the parties.

(c) In addition to, and without regard to any limitations on, the indemnification provided for in Sections 3(a) and (b) but subject to the exceptions contained in Section 4, Section 6 and Section 8 below, the Indemnitee shall be indemnified and held harmless by the Company against all Indemnifiable Amounts if, by reason of the Indemnitee’s Position, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company) provided that in no circumstances shall the Company be obligated to make any payment to the Indemnitee that it is advised by its legal advisers would be unlawful under the laws of Jersey or is prohibited by the Articles.

4. Exceptions to Indemnification. The Indemnitee shall be entitled to indemnification under Section 3, provided, however, that the Company shall not indemnify or advance Expenses to Indemnitee with respect to any act, event or circumstance with respect to which it is prohibited to do so under applicable law (including the Companies Law) or the Articles. Further the indemnity in Section 3 shall not apply to any liability incurred by the Indemnitee (i) to the Company; (ii) to any Subsidiary; (iii) to pay a fine imposed in criminal proceedings or a sum payable to a regulatory authority by way of a penalty in respect of non-compliance with any requirement of a regulatory nature (however arising); (iv) in defending any criminal proceedings in which the Indemnitee is convicted; (v) in defending any civil proceedings brought by the Company, or a Subsidiary, in which judgment is given against the Indemnitee; (vi) in the event that the liability incurred by the Indemnitee is, in the reasonable opinion of the Board, a result of fraud or wilful misconduct by the Indemnitee; (vii) in defending any proceedings brought by a regulatory authority in which a penalty is imposed on the Indemnitee; or (viii) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (a) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (b) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law and the Articles. The Company and the Indemnitee acknowledge and agree that nothing in this Section 4 shall preclude the Indemnitee from making claims against the Company to enforce the Indemnitee’s rights under this Agreement.

6. Indemnification for Expenses if Indemnitee is Wholly or Partly Successful. Notwithstanding anything contained in this Agreement to the contrary, to the extent that the Indemnitee is, by reason of the Indemnitee’s Position, a party to and is successful, on the merits or otherwise, in any Proceeding, the Indemnitee shall, subject always to the provisions of the Companies Law, the Articles and all other applicable laws, be indemnified against all Indemnifiable Amounts in connection therewith. If the Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall subject always to the provisions of the Companies Law, the Articles and all other applicable laws indemnify the Indemnitee against all Indemnifiable Amounts in connection with each successfully resolved claim, issue or matter. For purposes of this Agreement, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. Notwithstanding any of the foregoing, nothing in this Section 6 shall be construed to limit an Indemnitee’s right to indemnification which he or she would otherwise be entitled to pursuant to Section 3 hereof, regardless of the Indemnitee’s success in a Proceeding.

8. Agreement to Advance Expenses; Conditions.

(a) Subject to applicable law and the provisions of this Agreement, the Company will fund all of the legal and other expenses (“Defence Costs”) properly incurred or to be properly incurred by the Indemnitee in defending any criminal or civil proceedings in connection with any alleged negligence, default, breach of duty or breach of trust by him in relation to the Company or in connection with any Relevant Application. Any request for funding under this Section 8 shall be made in writing by the Indemnitee to the Company and determined by resolution of the Board, subject to such conditions as the Board thinks fit.

(f) The Indemnitee shall take all reasonable action to mitigate any loss suffered by him in respect of such Defence Costs.

10. Remedies of Indemnitees.

(c) Failure to Act Not a Defence. The failure of the Company (including the Board or any committee thereof, independent legal counsel, or shareholders) to make a determination concerning the permissibility of the payment of Indemnifiable Amounts or the advancement of Indemnifiable Expenses under this Agreement shall not be a defence in any action brought under Section 10(a) above, and shall not create a presumption that such payment or advancement is not permissible.

(a) In addition, the Indemnitee shall:

(i) as soon as practicable, give written notice of such circumstances to the Company;

(v) take all reasonable action to mitigate any loss suffered by him in respect of such Indemnifiable Amounts or Indemnifiable Expenses.
