                  reasonably,  that  the  development  of the  Project  does not
                  warrant  further  work,  it shall  have the  right to elect to
                  deliver the amount of any unspent Minimum Project Expenditures
                  Amount to the Costs  Trustee  to be dealt  with in  accordance
                  with the Costs Trust Agreement.

respect of IMA Barbados, IMA Argentina,  the Project, the Project Assets and the



                                      -11-



Contracts.  At any time during the Due  Diligence  Period,  Aquiline may deliver
written notice (the "ELECTION NOTICE") to IMA that it elects to receive from IMA
a transfer of the Navidad Assets and the Navidad Claims instead of a transfer of
the Shares and the  Contracts  in  accordance  with  Section  2.1.  If  Aquiline
delivers such  Election  Notice to IMA within such Due  Diligence  Period,  this
Agreement  will be deemed to be  automatically  amended in  accordance  with the
provisions  contained in Schedule H. Should  Aquiline not deliver such  Election
Notice to IMA by the end of the Due Diligence  Period, it will be deemed to have
elected to receive a transfer of the Shares and the Contracts in accordance with
Section  2.1  and  the  provisions   contained  in  Schedule  H  shall  have  no
application.

                  IMA,  its  obligation  to pay  Aquiline  Qualifying  Costs  to

                                    diligence  to  contest  or   discharge   any
                                    Encumbrance that is filed;

                           E.       pay,  when  due and  payable,  all  wages or
                                    salaries for services rendered in connection
                                    with the Project Assets and all accounts for
                                    materials  supplied  on or in respect of any
                                    work or operation  performed on such Project
                                    Assets; and

                           F.       do or  cause  to be  done  all  work  on the
                                    Project  Assets  in a good  and  workmanlike
                                    fashion   and   in   accordance   with   all
                                    applicable  laws,  regulations,  orders  and
                                    ordinances of any governmental authority.

         (b)      Provided that IMA has received  written  notice of and minutes
                  from a particular Management Committee Meeting or a particular
                  Aquiline Management Meeting, as the case may be, in accordance
                  with  Section   3.2(a)(vii)C  and  in  the  event  that  IMA's
                  representative at such Management Committee Meeting or at such
                  Aquiline  Management  Meeting,  as the case  may be,  does not
                  provide written notice disputing  expenditures  proposed to be
                  incurred by Aquiline and/or its Subsidiaries in respect of the
                  Project within five (5) business days following receipt of the
                  minutes of such Management  Committee Meeting or such Aquiline



                                      -16-


                  Management  Committee Meeting, as the case may be, IMA will be
                  deemed  to  have  agreed  that  such  expenditures  constitute
                  Aquiline    Qualifying   Costs.    Non-attendance   by   IMA's
                  representative  at a  Management  Committee  Meeting  or  at a
                  Aquiline  Management  Meeting,  as the case may be,  shall not
                  prevent  IMA's  representative  from  disputing   expenditures
                  proposed to be incurred by Aquiline and/or its Subsidiaries in
                  respect of the Project.

         (c)      In the event that IMA,  acting  reasonably,  provides  written
                  notice disputing  proposed  expenditures  within the permitted
                  time period,  the matter  shall be referred to an  independent
                  geological consultant (the "TECHNICAL CONSULTANT") selected by
                  agreement  between the Parties or,  failing  agreement  within
                  five  Business Days from the dispute  notice,  selected by the
                  President for the time being of CIM. The Technical  Consultant
                  will be  authorized  to review and approve or  disapprove  any
                  disputed proposed expenditures and its decision shall be final
                  and  binding  upon the  Parties.  The costs of  retaining  the
                  Technical  Consultant  shall be borne  equally by Aquiline and
                  IMA.

         (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

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).

         (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 3.4 shall,



                                      -20-


                  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 3.4 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.
                  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.

         (c)      The Pledgor and the Secured  Party  hereby  acknowledge  their
                  mutual  intention that the security  interest  created by this
                  Section 3.4 is to attach upon the execution of this  Agreement
                  by the  Pledgor  and that  value  has been  given and that the
                  Pledgor has rights in the Collateral as of the date hereof.

         (d)      In the  event  that the  Pledgor  fails to  direct  the  Costs
                  Trustee to pay to the Secured Party the amount  referred to in
                  Section  3.2(d)(i) or the Pledgor  fails to pay to the Secured
                  Party an amount equal to the  Aquiline  Qualifying  Costs,  or
                  fails to pay the Aquiline Disputed Amount to the Costs Trustee
                  (all such amounts collectively referred to in this Section 3.4
                  as the  "OBLIGATIONS")  within the  respective  specified time
                  periods for such  payments  provided in Section  3.2(e),  then
                  immediately  on the  expiration  of  such  time  periods,  the
                  security hereby constituted in respect of the Collateral shall
                  become immediately enforceable.

         (e)      Upon the security hereby constituted becoming enforceable, the
                  Secured Party,  in addition to exercising all other rights and
                  remedies to which it may be entitled at law or hereunder,  and
                  without  restricting the generality  thereof, is authorized to
                  realize on the Collateral,  subject to applicable law, without
                  further  notice to any party  whomsoever and the Secured Party
                  may also sell the Collateral by private sale or otherwise.

         (f)      At any sale pursuant to this Section 3.4, the Secured Party is
                  authorized, if it deems it advisable to do so, to restrict the
                  prospective   bidders  or   purchasers  to  persons  who  will
                  represent  and agree  that they are  purchasing  for their own
                  account for investment and not with a view to the distribution
                  or resale of any of the  Collateral.  The Secured  Party shall
                  have  the  right  to  deliver,  assign  and  transfer  to  the
                  purchaser,  or purchasers,  the Collateral or any part thereof
                  and the  Collateral  may be  sold  in one  lot or in  separate
                  units,  in the  discretion of the Secured  Party.  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. The reasonable costs of the
                  Secured  Party   incurred  in  protecting  and  realizing  the
                  Collateral shall be added to and included in 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.

                  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

                  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.
                  Without  derogating  from the Trust  Conditions,  it is hereby
                  understood and agreed that the  responsibility  of the Nominee



                                      -22-


                  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.

         (c)      The Pledgor and the Secured  Party  hereby  acknowledge  their
                  mutual  intention that the security  interest  created by this
                  Section 3.5 is to attach upon the execution of this  Agreement
                  by the  Pledgor  and that  value  has been  given and that the
                  Pledgor has rights in the Collateral as of the date hereof.

         (d)      In the  event  that the  Pledgor  fails to  direct  the  Costs
                  Trustee to pay to the Secured Party the amount  referred to in
                  Section  3.2(e)(i) or the Pledgor  fails to pay to the Secured
                  Party the amounts referred to in Section  3.2(e)(ii) (all such
                  amounts  collectively  referred to in this  Section 3.5 as the
                  "OBLIGATIONS")  within the  respective  specified time periods
                  for such payments provided in Section 3.2(d), then immediately
                  on the  expiration of such time periods,  the security  hereby
                  constituted  in  respect  of  the   Collateral   shall  become
                  immediately enforceable.

         (e)      Upon the security hereby constituted becoming enforceable, the
                  Secured Party,  in addition to exercising all other rights and
                  remedies to which it may be entitled at law or hereunder,  and
                  without restricting the generality thereof, is authorized to:

                  (i)      direct  the  Nominee  to   forthwith   transfer   the
                           Collateral to the Secured Party or a party  nominated
                           by it; and

                  (ii)     realize on the Collateral, subject to applicable law,

                           private sale or otherwise.

         (f)      At any sale pursuant to this Section 3.5, the Secured Party is
                  authorized, if it deems it advisable to do so, to restrict the
                  prospective   bidders  or   purchasers  to  persons  who  will
                  represent  and agree  that they are  purchasing  for their own
                  account for investment and not with a view to the distribution
                  or resale of any of the  Collateral.  The Secured  Party shall
                  have  the  right  to  deliver,  assign  and  transfer  to  the
                  purchaser,  or purchasers,  the Collateral or any part thereof
                  and the  Collateral  may be  sold  in one  lot or in  separate
                  units,  in the  discretion of the Secured  Party.  The Secured
                  Party may,  without notice or publication,  adjourn any public
                  or private sale or cause the same to be adjourned from time to

         (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. The reasonable costs of the



                                      -23-


                  Secured  Party   incurred  in  protecting  and  realizing  the
                  Collateral shall be added to and included in 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.

                  Indemnified Party may become subject or otherwise  involved in

                  indirectly:

                  (i)      any   misrepresentation   contained   in  the  public
                           disclosure  documents of IMA dated either prior to or
                           after   the   date  of  this   Agreement   (an   "IMA
                           MISREPRESENTATION"); or

                  (ii)     any  liability to persons  other than Aquiline or its
                           Affiliates (whether accrued, absolute,  contingent or
                           otherwise)  of IMA  Barbados or IMA  Argentina  which
                           arose  on or  prior  to the  Transfer  Date  (an "IMA
                           LIABILITY").

                  IMA also agrees that no Aquiline  Indemnified Party shall have
                  any liability (whether direct or indirect, in contract or tort
                  or otherwise) to IMA or any person  asserting claims on behalf
                  of or in  right  of  IMA  for  or in  connection  with  an IMA
                  Misrepresentation  or an IMA  Liability,  save  for  liability
                  arising  from  fraud or gross  negligence  on the part of such
                  Aquiline  Indemnified  Party. IMA will not, without Aquiline's
                  prior  written  consent,  settle,  compromise,  consent to the
                  entry of any  judgement in or otherwise  seek to terminate any
                  action, suit, proceeding, investigation or claim in respect of

                                      -24-


                  any Aquiline Indemnified Party is a party thereto) unless such
                  settlement,  compromise,  consent  or  termination  includes a
                  release   of  each   Aquiline   Indemnified   Party  from  any
                  liabilities  arising  out of such  action,  suit,  proceeding,
                  investigation or claim.

         (b)      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, Aquiline agrees to

                  and each of the directors  and officers  which IMA appoints to

                  and IMA Argentina following the re-transfer of the Trust Assts
                  in accordance with Section 3.2(d)(iii) (collectively, the "IMA
                  INDEMNIFIED  PARTIES" and  individually,  an "IMA  INDEMNIFIED
                  PARTY"), from and against any and all losses, expenses, claims
                  (including  shareholder  actions,  derivative  or  otherwise),
                  actions, damages and liabilities,  joint or several, including
                  the  aggregate  amount paid in  reasonable  settlement  of any
                  actions, suits, proceedings,  investigations or claims and the
                  reasonable  fees and  expenses  of their  counsel  that may be
                  incurred  in advising  with  respect to and/or  defending  any
                  action, suit,  proceeding,  investigation or claim that may be
                  made or  threatened  against any IMA  Indemnified  Party or in
                  enforcing this indemnity (collectively, the "AQUILINE CLAIMS")
                  to which any IMA  Indemnified  Party  may  become  subject  or
                  otherwise  involved in any  capacity  insofar as the  Aquiline
                  Claims relate to, are caused by, result from,  arise out of or
                  are based upon, directly or indirectly,

                  (i)      any   misrepresentation   contained   in  the  public
                           disclosure  documents  of Aquiline  dated prior to or
                           after  the  date  of  this  Agreement  (an  "AQUILINE
                           MISREPRESENTATION"); or

                  (ii)     any  liability  to  persons  other  than  IMA  or its
                           Affiliates (whether accrued, absolute,  contingent or
                           otherwise)  of IMA  Barbados or IMA  Argentina  which
                           arose   during  the  Trust   Period   (an   "AQUILINE
                           LIABILITY").

                  Aquiline also agrees that no IMA Indemnified  Party shall have
                  any liability (whether direct or indirect, in contract or tort
                  or  otherwise) to Aquiline or any person  asserting  claims on
                  behalf of or in right of Aquiline for or in connection with an
                  Aquiline  Misrepresentation or an Aquiline Liability, save for
                  liability  arising from fraud or gross  negligence on the part
                  of such IMA  Indemnified  Party.  Aquiline  will not,  without
                  IMA's prior written consent,  settle,  compromise,  consent to
                  the entry of any  judgement in or otherwise  seek to terminate
                  any  action,  suit,  proceeding,  investigation  or  claim  in
                  respect  of  which  indemnification  may be  sought  hereunder
                  (whether or not any IMA Indemnified  Party is a party thereto)
                  unless such  settlement,  compromise,  consent or  termination
                  includes  a release  of each IMA  Indemnified  Party  from any
                  liabilities  arising  out of such  action,  suit,  proceeding,
                  investigation or claim.

         case the Costs Trustee will comply with such authorization.

8.       The Costs  Trustee is  authorized to deliver the Costs Trust Amount out
         of escrow:

         (a)      to  Aquiline,  in the event  that the Costs  Trustee  receives
                  written  confirmation  from IMA and  Aquiline  that the  Trust
                  Assets  have  been  transferred  to IMA  pursuant  to  Section
                  3.2(d), (f) or (g), as the case may be, of the Interim Project

                  confirmation   from  IMA  and  Aquiline  that  the  Trust  has
                  terminated  in accordance  with Section  3.2(e) of the Interim
                  Project Development Agreement.

         to Section 3.2(d)(ii) of the Interim Project Development Agreement.

10.      Aquiline  and IMA  agree to act  honestly  and in good  faith and in as
         expeditious  a manner as may be  reasonably  necessary  to fulfil their
         respective   obligations   respecting   the   signing  of  the  written
         confirmation  contemplated  in Section  8(a) and  Section  8(b) and, if
         applicable,  the written  direction  contemplated by Section 9, of this
         Agreement.

11.      If the Costs  Trustee  receives any other notice in writing (a "RELEASE
         NOTICE")  signed by all of the Parties,  directing the Costs Trustee to


                                      B-4



         deliver any Trust Amount or part thereof to either Aquiline or IMA, the
         Costs  Trustee  will comply with such  Release  Notice  within five (5)
         Business Days after receipt of such Release  Notice or such later date,
         if any, as is specified in such  Release  Notice.  If, on or before the
         third  anniversary  of the  Transfer  Date,  the Costs  Trustee has not
         received a Release  Notice or a notice in writing (a "DISPUTE  NOTICE")
         signed by either  Aquiline or IMA, or both,  advising the Costs Trustee
         that there is a dispute  between  Aquiline  and IMA with respect to the

NATURE OF COSTS TRUSTEE RESPONSIBILITIES

         those which are expressly set forth in this  Agreement  and, in respect
         of such duties, the Costs Trustee:

         (a)      will have no discretion as to the  performance  of such duties
                  and satisfaction of such obligations; and

         (b)      will not be  bound by any  notice  of  claim  or  demand  with
                  respect  to  such  duties  and  obligations,  or  any  waiver,
                  modification,  amendment,  termination  or  rescission of this
                  Agreement, unless received by the Costs Trustee in writing and
                  signed by each other party hereto and unless the Costs Trustee
                  has  given  its  written  consent  thereto  if its  duties  or
                  obligations hereunder are affected.

14.      The Costs Trustee will not be  responsible  to investigate or determine

         Trustee is hereby  authorized  and directed to comply with and obey any
         order,  judgement,  decree  or award of the  Supreme  Court of  British
         Columbia  and, in the case of such  compliance,  the Costs Trustee will
         not be liable by reason  thereof to any person even if thereafter  such
         order,  judgement,  decree or award is  appealed,  reversed,  modified,
         annulled, set aside or vacated.

16.      Notwithstanding  any  other  provision  of this  Agreement,  if for any
         reason the Costs Trustee  determines in good faith that it is unable to
         identify  clearly the person or persons  entitled to receive all or any
         portion of a Trust  Amount,  the Costs  Trustee  may refuse to make any
         payment  of such Trust  Amount  and may retain the Trust  Amount in its
         possession  or control  subject to  receipt  of further  directions  in
         accordance with this Agreement.

17.      The Costs  Trustee  will not by reason  hereof be required to initiate,
         defend or otherwise  prosecute  any legal  proceeding in respect of any
         matter arising out of or in connection  with this Agreement  unless and
         until jointly and severally indemnified  (including indemnity by way of
         advance  deposit  with the Costs  Trustee of amounts  estimated  by the
         Costs  Trustee of the costs  (including  legal costs on a solicitor and
         his own client basis), expenses,  awards,  judgements,  amounts paid in
         settlement  of claims or otherwise  that the Costs  Trustee  determines
         might  be  incurred  or  suffered  in  or as a  result  of  such  legal
         proceedings)  to the complete and unfettered  satisfaction of the Costs
         Trustee.

18.      The Costs  Trustee  may act  relative  hereto  upon the advice of legal
         counsel,  chartered  accountants  or  other  professional  advisors  in
         reference to any matter  pertaining  hereto and will incur no liability
         in respect of any action taken, omitted or suffered by it in good faith
         in accordance with the advice of any such counsel or other advisor.

19.      The Costs  Trustee  will not be liable for any act or failure to act by
         any representative,  legal counsel, accountant,  banker, agent or other
         person  appointed to act in any matter  pertaining to a Trust Amount or
         be bound to supervise the conduct of any such person.

LIMITATION OF COSTS TRUSTEE'S LIABILITY

20.      Notwithstanding  any  other  provision  in this  Agreement,  the  Costs
         Trustee will not be liable for any error of judgement,  fact or law, or
         for any act done or omitted to be done (including any negligence on the
         part of the Costs  Trustee),  except for the Costs Trustee's own wilful
         misconduct or gross negligence.

FEES AND EXPENSES OF COSTS TRUSTEE

21.      IMA will pay the fees of and expenses  incurred by the Costs Trustee in
         connection  with  the  performance  of  its  duties  hereunder  and  in

         its acting as and being the costs trustee hereunder.


                                      B-6



22.      The Costs Trustee shall not be required to expend or risk its own funds
         or otherwise incur  financial  liabilities in the performance of any of
         its  duties,  or in the  exercise  of any of  its  rights  and  powers,
         hereunder.

INDEMNIFICATION OF COSTS TRUSTEE

23.      Aquiline and IMA covenant and agree to indemnify  and save harmless the
         Costs Trustee,  its partners,  employees,  independent  contractors and
         agents and their respective heirs, executors, administrators,  personal
         representatives  and  assigns,  as the case may be  (collectively,  the
         "INDEMNIFIED  PARTIES"),  from and against,  on a full indemnity basis,
         all claims,  demands,  damages,  losses,  liabilities,  amounts paid in
         settlement  of claims,  costs and  expenses  and other  amounts paid in
         respect of any civil, criminal or administrative action,  proceeding or
         investigation to which the Indemnified  Parties, or any of them, as the
         case may be,  is made a party or is  subject  by  reason  of the  Costs
         Trustee  performing its duties as costs trustee  hereunder or otherwise
         arising out of or connected  with this  Agreement  except for the Costs
         Trustee's own wilful  misconduct or gross  negligence.  Aquiline's  and
         IMA's  obligations  under this  section are joint and several and shall
         survive the  resignation  or  replacement  of the Costs Trustee and the
         termination of this Agreement.

RESIGNATION AND SUCCESSORSHIP

24.      The Costs  Trustee may resign as costs  trustee  hereunder  at any time
         upon giving 30 days' advance written notice of such resignation to each
         other party to this Agreement,  provided that such resignation will not
         be  effective  until a successor  costs  trustee has been  appointed by
         agreement of IMA and  Aquiline.  If a successor  costs  trustee has not
         been  appointed or has not  accepted  such  appointment  within 20 days
         after the Costs Trustee gives notice of resignation,  the Costs Trustee
         may apply to the Supreme Court of British  Columbia for the appointment
         of a successor  costs  trustee and the  expenses  incurred by the Costs
         Trustee in so doing will be paid by IMA in accordance with Section 21.

25.      IMA and Aquiline,  acting together, may remove the Costs Trustee at any
         time by giving  the Costs  Trustee  30 days'  advance  written  notice,
         jointly signed by them,  which notice will include the name and contact
         details of the replacement costs trustee.

26.      Any new costs trustee  appointed  hereunder  will execute an instrument
         accepting such appointment and deliver one counterpart  thereof to each
         of IMA,  Aquiline and the existing  Costs  Trustee,  and thereupon such
         newly  appointed  Costs Trustee,  without  further act or notice,  will
         become vested in all rights,  powers and obligations of its predecessor
         for  execution  of  the  mandate  hereunder,  with  like  effect  as if
         originally named as the Costs Trustee herein, and the predecessor Costs
         Trustee  will  forthwith  deliver  any Trust  Amount in its  possession
         pursuant to this Agreement to the new costs  trustee,  for the purposes
         and uses of this Agreement.

                                      B-7




TERMINATION OF OBLIGATIONS

27.      Upon  payment  out of escrow by the Costs  Trustee  of all of the Trust
         Amounts in accordance with this Agreement, the obligations of the Costs
         Trustee hereunder will terminate and the Costs Trustee will be released
         and discharged from all further obligations hereunder.

28.      Upon due and proper  delivery of notice of resignation or  replacement,
         as the case may be, of a Costs  Trustee  pursuant  to Section 24 or 25,
         and upon delivery by such Costs Trustee of a Trust Amount in accordance
