(d) In the event that Aquiline (including its successors and permitted assigns) is determined not to be the Ultimate Owner and the Appeal Termination Date is reached: (i) the Parties will cause the Costs Trustee to deliver to Aquiline, as soon as reasonably practicable following the Appeal Termination Date and in any event no later than five (5) business days following the Appeal Termination Date, the Minimum Trust Amount (plus any interest accrued thereon) and any unspent Minimum Project Expenditures Amount delivered to the Costs Trustee in accordance with Section 2.3(c) (plus any interest accrued thereon); (ii) subject to Section 2.5(d), IMA will pay to Aquiline (by way of a certified cheque or bank draft payable to Aquiline), as soon as reasonably practicable following the Appeal Termination Date and in any event no later than twenty (20) business days following the Appeal Termination Date, the amount of the Aquiline Qualifying Costs; provided that if Aquiline, acting reasonably, disputes the correctness of the amount so paid, IMA shall deliver to the Costs Trustee an amount (the "AQUILINE DISPUTED AMOUNT") equal to the difference between the amount so paid and the amount of Aquiline Qualifying Costs that Aquiline notifies IMA in writing to be the correct Aquiline Qualifying Costs payable and the Parties shall cause the Costs Trustee to deliver such Aquiline Disputed Amount to Aquiline and/or IMA, as the case may be, as agreed in writing by the Parties following resolution of such dispute between them or as soon as reasonably practicable following the conclusion of any arbitration to settle such dispute; and (iii) the Trustee will, as soon as reasonably practicable following payment to Aquiline in accordance with Sections 3.2(d)(i) and (ii) and/or to the Costs Trustee in accordance with 3.2(d)(ii) (as the case -17- may be), re-transfer the Trust Assets (save for any Non-Key Contracts that may have been assigned, disposed of or terminated), together with all loan claims against IMA Barbados or IMA Argentina to IMA or its nominees MUTATIS MUTANDIS on the same basis as is set out in Section 2.1, whereupon the Trust shall be terminated and IMA or its nominees shall then hold sole legal and beneficial title to the Trust Assets. (e) In the event that Aquiline (including its successors and permitted assigns) is determined to be the Ultimate Owner and the Appeal Termination Date is reached: (i) the Parties will cause the Costs Trustee to deliver, as soon as reasonably practicable following the Appeal Termination Date and in any event no later than five (5) business days following the Appeal Termination Date, to IMA the Minimum Trust Amount (plus any interest accrued thereon); (ii) subject to Section 2.5(d), Aquiline will pay to IMA (by way of a certified cheque or bank draft payable to the IMA), as soon as reasonably practicable following the Appeal Termination Date and in any event no later than twenty (20) business days following the Appeal Termination Date, the Minimum Project Expenditure Amount; and (iii) on the date upon which the last of the payments contemplated by Sections 3.2(e)(i) and 3.2(e)(ii) is made, the Trust shall terminate and Aquiline shall then hold sole legal and beneficial title to the Trust Assets. (f) In the event that the Appeal Decision does not determine the sole beneficial ownership of the Navidad Assets and the Navidad Claims and does not award sole beneficial ownership of the Shares to any Party (including its successors and permitted assigns) such that the Ultimate Owner cannot be determined based on the Appeal Decision, and the Appeal Termination Date is reached, then in such case the Trust shall terminate and the Trustee will re-transfer the Trust Assets (save for any Non-Key Contracts that may have been assigned, disposed of or terminated) to IMA or its nominees MUTATIS MUTANDIS on the same basis as is set out in Section 3.2(d), save to the extent otherwise provided in accordance with such Appeal Decision. For greater certainty, the Trustee shall comply strictly with the terms of any such Appeal Decision and, if applicable, the SCC Decision. (g) In the event that the Appeal Decision does not determine that sole beneficial ownership of the Navidad Assets and the Navidad Claims be, and/or does not award sole beneficial ownership of the Shares to be, vested in Aquiline (including its successors and permitted assigns) and there is a Further Appeal but the SCC Decision does not determine the sole beneficial ownership of the Navidad Claims and does not award -18- sole beneficial ownership of the Shares to any Party (including its successors and permitted assigns) such that the Ultimate Owner cannot be determined based on the SCC Decision, then in such case the Trust shall terminate and the Trustee will re-transfer the Trust Assets (save for any Non-Key Contracts that may have been assigned, disposed of or terminated) to IMA or its nominees MUTATIS MUTANDIS on the same basis as is set out in Section 3.2(d), save to the extent otherwise provided in accordance with such Appeal Decision. For greater certainty, the Trustee shall comply strictly with the terms of any such Appeal Decision and, if applicable, the SCC Decision. (h) The Parties do not intend that there shall be any violation of the rule against perpetuities, the rule against unreasonable restraints on the alienation of property, or any similar rule (the "RULE"). Accordingly, it is intended that all rights and interests in the Trust Assets under this Agreement vest within the Appeal Period and if for any reason the Appeal Period is longer than permitted by the Rule, the Parties hereby agree that a court shall reform that provision in such a way as to approximate most closely the intent of the Parties within the limits permissible under the Rule. (i) The Trust and the Parties are not, shall not be deemed to be and shall not be treated as, a general partnership, limited partnership, society, syndicate, association or joint venture, nor shall the Trustee or the Parties or any of them or any person be, or be deemed to be, treated in any way whatsoever as liable or responsible hereunder as partners or joint venturers. The Trustee is not and shall not be, or be deemed to be, an agent of the Parties except as expressly set out herein. The relationship of IMA to the Trustee shall be solely that of a potential beneficiary of the Trust and their rights shall be limited to those conferred upon them by this Agreement. (j) Neither IMA and IMA Argentina, in its capacity as a Party, shall incur or be subject to any liability, direct or indirect, absolute or contingent, in contract or in tort or of any other kind to any person in connection with: (i) the Trust or the ownership, use, operation, acquisition or disposition thereof or exercise or enjoyment of the rights, privileges, conditions or benefits attached thereto, associated therewith or derived therefrom; (ii) the obligations or the activities or affairs of the Trust; (iii) any actual or alleged act or omission of the Trustee or by any other person in respect of the activities or affairs of the Trust (whether or not authorized by or pursuant to this Agreement); (iv) any actual or alleged act or omission of the Trustee or of any other person in the performance or exercise, or purported or attempted performance or exercise, of any obligation, power, discretion or authority conferred upon the Trustee or such other person in respect of the activities or affairs of the Trust (whether or not authorized by or pursuant to this Agreement); -19- (v) any transaction entered into by the Trustee or by any other person in respect of the activities or affairs of the Trust (whether or not authorized by or pursuant to this Agreement); or (vi) except as provided in Section 3.2(d), any taxes, levies, imposts or charges or fines, penalties or interest in respect thereof payable by the Trust or by the Trustee or by any other person (except the Party to the extent required by applicable tax laws) on behalf of or in connection with the activities or affairs of the Trust (collectively, "TRUST LIABILITIES"). (k) In the event of transfer to IMA in accordance with the provision of this Section 3.2(j) of any Trust Assets comprising Shares, the Trustee shall ensure that, prior to such transfer, all loan claims against the Subsidiaries to which such Shares relate shall have been capitalized. (l) Neither IMA nor IMA Argentina in its capacity as a Party shall be liable to indemnify the Trustee or any other person with respect to any Trust Liabilities. (m) To the extent that, notwithstanding the provisions of Section 3.2(j), any person makes a claim in respect of Trust Liabilities against IMA and IMA Argentina, Aquiline shall indemnify and hold harmless such Party in respect of such claim and any liability thereunder. 3.3 AMENDMENT OF TRUST CONDITIONS The Trust Conditions may be amended by mutual written agreement of IMA and Aquiline. For greater certainty, in the event that the Appeal is settled, IMA and Aquiline shall agree on the terms of the termination of the Trust. 3.4 IMA SECURITY (a) IMA (hereinafter in this Section 3.4 referred to as the "PLEDGOR") hereby grants a security interest in and pledges, assigns and transfers to Aquiline (hereinafter referred to in this Section 3.4 as the "SECURED PARTY") all of the Pledgor's interest in and to the Shares together with all renewals thereof, substitutions therefor and accretions thereto and all income and other proceeds therefrom (all such Shares renewals thereof, substitutions therefor, accretions thereto and income therefrom herein collectively referred to in this Section 3.4 as the "COLLATERAL") and agrees that such Collateral and any further Collateral which is hereafter deposited in pledge with the Trustee as the nominee of the Secured Party (referred to in this Section 3.4 as the "NOMINEE") shall be held for the benefit of the Secured Party as continuing collateral security for the due payment and performance of the Obligations (as defined below).

Without derogating from the Trust Conditions, it is hereby understood and agreed that the responsibility of the Nominee hereunder is limited to exercising with regard to the Collateral the same degree of care which the Secured Party gives to its valuable property of the same value and kind.

The Secured Party may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may without further notice be made at any time or place to which the same may be so adjourned. -21- (g) Before realizing on the Collateral, the Secured Party shall not be required to realize any other security. (h) Any sum collected by the Secured Party on the Collateral or the proceeds of its realization may be held as additional collateral security for or may be applied, on the terms set out in the Interim Project Development Agreement, to the payment of any of the Obligations.

(i) The Secured Party may grant discharges, settle by compromise, renounce rights or grant extensions with respect to the Collateral. The Secured Party may also settle by compromise and grant extensions without affecting its other rights hereunder. (j) In realizing upon the Collateral, the Secured Party shall not be responsible for any loss occasioned by any sale or other realization thereof or for the failure to sell or otherwise dispose of the Collateral, provided such realization was conducted in a commercially reasonable manner. 3.5 AQUILINE SECURITY (a) Aquiline (hereinafter in this Section 3.5 referred to as the "PLEDGOR") hereby grants a security interest in and pledges, assigns and transfers to IMA (hereinafter referred to in this Section 3.5 as the "SECURED PARTY") all of the Pledgor's interest in and to the Shares together with all renewals thereof, substitutions therefor and accretions thereto and all income and other proceeds therefrom (all such Shares renewals thereof, substitutions therefor, accretions thereto and income therefrom herein collectively referred to in this Section 3.5 as the "COLLATERAL") and agrees that such Collateral and any further Collateral which is hereafter deposited in pledge with the Trustee as the nominee of the Secured Party (referred to in this Section 3.5 as the "NOMINEE") shall be held for the benefit of the Secured Party as continuing collateral security for the due payment and performance of the Obligations (as defined below). (b) Upon the deposit of any Shares in pledge pursuant to this pledge, the Pledgor shall be deemed to have deposited with the Nominee all certificates, if any, representing such Shares. All certificates deposited pursuant to this Section 3.5 shall, unless all necessary consents and approvals are obtained, not contain any reference to restrictions on the transfer of the Shares represented thereby and shall be in bearer form or duly endorsed in blank for transfer or shall be attached to duly executed powers of attorney or forms of transfer. The Nominee shall hold the Collateral as agent of the Secured Party for all purposes whatsoever in accordance with the terms of this Section 3.5 and shall hold the Collateral for and on behalf of the Secured Party in the same manner and with the same effect as if the Secured Party held the Collateral itself in accordance with the Interim Project Development Agreement.
