            become a party to, any lease with  respect  to real  property  other
            than  the  Leases,  copies  of  which  have  been  provided  to  the
            Purchaser. Each Lease is in good standing,  creates a good and valid
            leasehold estate in the Leased Properties  thereby demised and is in
            full force and effect  without  amendment,  except as  disclosed  in
            Schedule 3.2(r) attached hereto.  With respect to each Lease (i) the

            event,  occurrence,  condition or act (including the purchase of the
            Purchased  Shares)  which,  with the giving of notice,  the lapse of
            time or the happening of any other event or condition,  would become
            a  default  under  the  Lease,  and  (v)  to  the  knowledge  of the
            Corporation,  all of the  covenants  to be  performed  by any  party
            (other  than the  Corporation)  under  the  Lease  have  been  fully
            performed.  Each of the Leased  Properties  is adequate and suitable
            for the  purposes  for  which  it is  presently  being  used and the
            Corporation  has adequate  rights of ingress and egress into each of
            the Leased  Properties  for the  operation  of the  Business  in the
            Ordinary Course.  Schedule 3.2(r) attached hereto contains a list of

            legal description), the term of the Lease, the rental payments under
            the Lease  (specifying  any  breakdown  of base rent and  additional

                  the aggregate;

            (vi)  any confidentiality, secrecy or non-disclosure Contract or any

                  any line of business,  compete with any other Person,  operate
                  its assets at maximum production capacity or otherwise conduct

            of the obligations required to be performed by it and is entitled to
            all  benefits  under,  and is not  alleged  to be in  default of any

            and effect and there exists no default or event of default or event,
            occurrence,   condition  or  act  (including  the  purchase  of  the

            proceeding  (collectively  "Legal  Proceedings") by or before (or to
            the  knowledge  of  the  Corporation  any   investigation   by)  any
            Governmental   Entity   pending,   or,  to  the   knowledge  of  the
            Corporation,   threatened   against  or  adversely   affecting   the

            Corporation  has no  knowledge  of a valid  basis for any such Legal
            Proceedings by or against the  Corporation.  The  Corporation is not
            subject to any judgment,  order or decree  entered in any lawsuit or
            proceeding nor has the Corporation  settled any claim prior to being
            prosecuted in respect of it.

      (hh)  Taxes.  The Corporation has filed or caused to be filed,  within the

            local and foreign tax returns and tax reports  which are required to
            be filed by or with  respect  to the  Corporation.  The  information
            contained in such  returns and reports is correct and complete  and,
            to the  knowledge  of the  Corporation,  such  returns  and  reports
            reflect  accurately all liability for taxes of the  Corporation  for
            the periods  covered  thereby.  All federal,  provincial,  local and

            been fully paid or fully  disclosed  and fully  provided  for in the
            Books and Records and the Interim Financial Statements. There are no
            claims,  actions,  suits or proceedings (or, to the knowledge of the
            Corporation,  any investigation) pending, or to the knowledge of the
            Corporation,  threatened  against the  Corporation  or the  Acquired
            Properties  relating to taxes and the Corporation  knows of no valid
            basis for any such claim, action, suit, proceeding, investigation or
            discussion.  The  Corporation has withheld from each payment made by
            it the  amount  of all taxes and  other  deductions  required  to be
            withheld  therefrom  and has paid the same to the  proper  taxing or
            other authority within the time prescribed under any applicable Law.
            The  Corporation  is a  registrant  for  purposes of the tax imposed
            under Part IX of the Excise Tax Act (Canada).

                  had and would not  reasonably  be expected to have a Purchaser

                  the Exchange Act, of the Purchaser  have not, been the subject
                  of, nor does any officer or director of the Purchaser have any
                  reason  to  believe  that  Purchaser  or any of its  officers,
                  directors or  Affiliates  will be the subject of, any civil or
                  criminal  proceeding or  investigation by any federal or state

            (v)   any  agreement  under which the  consequences  of a default or
                  termination  would  reasonably be expected to have a Purchaser
                  Material Adverse Effect;

            (vi)  has not,  and the past and  present  officers,  directors  and

                        local or foreign  government,  or any agency thereof, or
                        other political  subdivision of the United States or any
                        such  government,  and any interest,  fines,  penalties,
                        assessments   or  additions  to  tax   resulting   from,
                        attributable  to or incurred in connection  with any tax
                        or any contest or dispute thereof.

                  (B)   "Tax Returns" means all reports, returns,  declarations,
                        statements or other information  required to be supplied

            (ii)  By the Closing the Purchaser  shall have filed all Tax Returns
                  that it was required to file, and all such Tax Returns will be
                  complete and accurate in all  material  respects.  Neither the
                  Purchaser nor any subsidiary is or has ever been a member of a
                  group  of  corporations  with  which  it has  filed  (or  been
                  required  to  file)  consolidated,  combined  or  unitary  Tax
                  Returns,  other than a group of which only the  Purchaser  and
                  the Subsidiaries are or were members.  The unpaid Taxes of the
                  Purchaser  and the  Subsidiaries  for tax periods  through the
                  Purchaser  Interim  Balance  Sheet  Date  do  not  exceed  the
                  accruals  and  reserves  for  Taxes  (excluding  accruals  and
                  reserves  for deferred  Taxes  established  to reflect  timing
                  differences  between  book and Tax  income)  set  forth on the
                  Purchaser Interim Balance Sheet. Neither the Purchaser nor any
                  subsidiary  has any actual or potential  liability for any Tax
                  obligation of any taxpayer  (including  without limitation any
                  affiliated  group  of  corporations  or  other  entities  that
                  included  the  Purchaser  or any  subsidiary  during  a  prior
                  period)  other than the Purchaser  and the  subsidiaries.  All
                  Taxes that the Purchaser or any  subsidiary is or was required
                  by law to  withhold  or  collect  have been duly  withheld  or
                  collected and, to the extent  required,  have been paid to the
                  proper Governmental Entity.

            (v)   Neither  the  Purchaser  nor any  subsidiary  has  undergone a

                  binding and enforceable and in full force and effect; (ii) the
                  agreement  will  continue  to be  legal,  valid,  binding  and
                  enforceable and in full force and effect immediately following

                  party,  is in breach or violation  of, or default  under,  any
                  such agreement,  and no event has occurred,  is pending or, to
                  the knowledge of the Purchaser,  is threatened,  which,  after
                  the giving of notice, with lapse of time, or otherwise,  would
                  constitute  a breach or  default by the  Purchaser  or, to the
                  knowledge  of  the  Purchaser,  any  other  party  under  such
                  contract.

      (y)   Accounts  Receivable.  All  accounts  receivable  of  the  Purchaser
            reflected  on  the  Purchaser   Interim   Balance  Sheet  are  valid
            receivables  subject to no setoffs or counterclaims  and are current
            and  collectible  (within  90 days  after the date on which it first
            became due and payable), net of the applicable reserve for bad debts
            on the Purchaser  Interim  Balance  Sheet.  All accounts  receivable
            reflected in the  financial or  accounting  records of the Purchaser
            that have arisen since the Purchaser  Interim Balance Sheet Date are
            valid  receivables  subject to no setoffs or  counterclaims  and are
            collectible  (within 90 days after the date on which it first became
            due and  payable),  net of a  reserve  for bad  debts  in an  amount
            proportionate to the reserve shown on the Purchaser  Interim Balance
            Sheet Date.

      (z)   Insurance.  Schedule  4.1(y)  attached  hereto lists each  insurance
            policy (including fire, theft, casualty, general liability,  workers
            compensation,   business   interruption,    environmental,   product
            liability  and  automobile  insurance  policies  and bond and surety
            arrangements)  to which the  Purchaser  is a party.  Such  insurance
            policies  are of the  type and in  amounts  customarily  carried  by
            organizations  conducting  businesses  or owning  assets  similar to
            those of the Purchaser. There is no material claim pending under any
            such  policy as to which  coverage  has been  questioned,  denied or
            disputed by the  underwriter  of such  policy.  All premiums due and
            payable under all such policies have been paid,  the Purchaser  will
            not be liable for retroactive premiums or similar payments,  and the
            Purchaser is otherwise in compliance  in all material  respects with
            the terms of such  policies.  The  Purchaser has no knowledge of any
            threatened termination of, or material premium increase with respect
            to,  any  such  policy.   Each  such  policy  will  continue  to  be
            enforceable and in full force and effect  immediately  following the
            Closing  in   accordance   with  the  terms  thereof  as  in  effect
            immediately prior to the Closing.

                  claims to benefits under any Employee  Benefit Plan that could
                  give rise to any material liability.

            (iv)  All  the  Employee  Benefit  Plans  that  are  intended  to be
                  qualified  under  Section  401(a)  of the Code  have  received
                  determination letters from the Internal Revenue Service to the
                  effect that such Employee  Benefit Plans are qualified and the
                  plans and the trusts  related  thereto are exempt from federal
                  income taxes under Sections  401(a) and 501(a),  respectively,
                  of the Code, no such determination letter has been revoked and
                  revocation  has not  been  threatened,  and no  such  Employee
                  Benefit  Plan  has  been  amended  since  the date of its most
                  recent  determination  letter or  application  therefor in any
                  respect,  and no act or  omission  has  occurred,  that  would
                  adversely affect its qualification or materially  increase its
                  cost. Each Employee  Benefit Plan which is required to satisfy
                  Section  401(k)(3)  or Section  401(m)(2) of the Code has been
                  tested for compliance with, and satisfies the requirements of,
                  Section  401(k)(3) and Section  401(m)(2) of the Code for each

            (v)   Neither the Purchaser, any subsidiary, nor any ERISA Affiliate
                  has ever  maintained  an  Employee  Benefit  Plan  subject  to
                  Section 412 of the Code or Title IV of ERISA.

            (vi)  At no time has the  Purchaser,  any  subsidiary  or any  ERISA
                  Affiliate been  obligated to contribute to any  "multiemployer
                  plan" (as defined in Section 4001(a)(3) of ERISA).

            (vii) There are no unfunded  obligations  under any Employee Benefit
                  Plan providing benefits after termination of employment to any
                  employee  of  the  Purchaser  or  any  subsidiary  (or  to any
                  beneficiary of any such  employee),  including but not limited
                  to retiree  health  coverage  and deferred  compensation,  but
                  excluding  continuation  of  health  coverage  required  to be
                  continued under Section 4980B of the Code or other  applicable
                  law and insurance  conversion  privileges under state law. The
                  assets of each  Employee  Benefit  Plan  which is  funded  are
                  reported at their fair  market  value on the books and records
                  of such Employee Benefit Plan.

            (viii) No act or omission has occurred and no condition  exists with
                  respect  to  any  Employee  Benefit  Plan  maintained  by  the
                  Purchaser,  any  subsidiary or any ERISA  Affiliate that would
                  subject the Purchaser,  any subsidiary or any ERISA  Affiliate
                  to (i) any  material  fine,  penalty,  tax or liability of any
                  kind imposed  under ERISA or the Code or (ii) any  contractual
                  indemnification  or  contribution  obligation  protecting  any
                  fiduciary,  insurer or service  provider  with  respect to any
                  Employee Benefit Plan.

            (ix)  No  Employee  Benefit  Plan is funded by,  associated  with or
                  related to a "voluntary  employee's  beneficiary  association"
                  within the meaning of Section 501(c)(9) of the Code.

            (x)   Each  Employee   Benefit  Plan  is  amendable  and  terminable
                  unilaterally by the Purchaser at any time without liability to
                  the  Purchaser  as a result  thereof and no  Employee  Benefit
                  Plan,   plan   documentation   or   agreement,   summary  plan
                  description   or  other  written   communication   distributed
                  generally to employees by its terms  prohibits  the  Purchaser
                  from amending or terminating any such Employee Benefit Plan.

                  plan  or  arrangement  under  which  any  person  may  receive

                  imposed  by  Section  4999  of the  Code  or  included  in the

                  or the vesting of the  benefits of which will be  accelerated,
                  by the occurrence of any of the  transactions  contemplated by
                  this  Agreement  or the value of any of the  benefits of which
                  will be  calculated  on the  basis of any of the  transactions

                  relating to premises currently or previously owned or operated
                  by the Purchaser or a subsidiary  (whether  conducted by or on
                  behalf of the Purchaser or a subsidiary or a third party,  and

                  party)  which  were  issued or  conducted  during the past two

            to  the  knowledge  of  the  Purchaser,  no  officer,   director  or
            stockholder  of Purchaser or any Affiliate or  "associate"  (as such
            term is  defined in Rule 405 under the  Securities  Act) of any such
            person has had,  either  directly or indirectly,  (a) an interest in
            any person that (i) furnishes or sells services or products that are
            furnished  or  sold  or are  proposed  to be  furnished  or  sold by
            Purchaser  or any  subsidiary  or (ii)  purchases  from or  sells or

            or affected.  Neither  Purchaser nor any  subsidiary has extended or
            maintained credit,  arranged for the extension of credit, or renewed
            an extension of credit, in the form of a personal loan to or for any
            director  or  executive  officer  (or  equivalent  thereof)  of  the
            Purchaser or any subsidiary.

            covered  by  such  financial  statements  (a)  a  registered  public
            accounting   firm  (as   defined   in   Section   2(a)(12)   of  the

            all non-audit  services  performed by Moen and Company for Purchaser

            for either of the past two fiscal years contained an adverse opinion
            or a disclaimer  of opinion,  or was  qualified  as to  uncertainty,
            audit scope, or accounting  principles.  During Purchaser's two most
            recent fiscal years and the subsequent  interim periods,  there were

            principles or practices, financial statement disclosure, or auditing
            scope or procedures.  None of the  reportable  events listed in Item
            304(a)(1)(iv)  of  Regulation  S-B occurred with respect to Moen and
            Company.

            Offering Memorandum of the Purchaser attached hereto as Schedule "E"
            contain  any  untrue  statements  of a  material  fact,  or  to  the
            Purchaser's  knowledge,  omit to state a material fact  necessary to
            make the  statements  contained  herein or  therein  in light of the
            circumstances under which they were made not misleading.

            therewith; and

                                INDEMNIFICATION

Section 9.1 Indemnification in Favour of the Purchaser

(1)   Subject to Section 9.5,  each Vendor shall  severally  indemnify  and save
      each of the Purchaser and the Purchaser's directors,  officers, agents and
      representatives  (collectively,  the "Purchaser's  Indemnified  Persons"),
      together with the Corporation and the Corporation's  directors,  officers,
      agents  and  representatives  harmless  of and from any  loss,  liability,
      claim,  damage or expense  (whether or not involving a third-party  claim)
      including legal expenses suffered by, imposed upon or asserted against any
      of the Purchaser's Indemnified Persons,  together with the Corporation and
      the Corporation's  directors,  officers,  agents and  representatives as a
      result of, in respect of,  connected  with, or arising out of,  under,  or
      pursuant to any and all debts,  obligations and other liabilities (whether
      absolute,  accrued,  contingent,  fixed or otherwise,  or whether known or
      unknown, or due or to become due or otherwise),  monetary damages,  fines,

      litigation) (collectively "Damages") incurred or suffered by the Purchaser
      or any Affiliate thereof  resulting from,  relating to or constituting any
      breach by such Vendor of the representations and warranties of such Vendor
      set out in Section 3.1 herein.

(2)   The  Corporation  shall  indemnify  and save the  Purchaser's  Indemnified
      Persons  harmless of and from any Damages  suffered  by,  imposed  upon or

      (a)   any failure of the Corporation to perform or fulfill any covenant of
            the Corporation under this Agreement; or

      (b)   any breach or inaccuracy of any  representation or warranty given by
            the Corporation contained in this Agreement

                                      -51-
<PAGE>

Section 9.2 Indemnification in Favour of the Vendor.

      The Purchaser shall  indemnify and save the Vendors and the  Corporation's
directors,  officers, employees, agents and representatives  (collectively,  the
"Vendors'  Indemnified  Persons")  harmless of and from any Damages suffered by,
imposed upon or asserted  against any of the Vendors'  Indemnified  Persons as a
result of, in respect of,  connected  with, or arising out of, under or pursuant
to:

      (a)   any failure of the  Purchaser  to perform or fulfil any  covenant of
            the Purchaser under this Agreement; or

      (b)   any breach or inaccuracy of any  representation or warranty given by
            the Purchaser contained in this Agreement.

provided that any claim against the Purchaser  shall be limited to an obligation
to deliver additional Goldstrike Shares as set out in Section 9.5.

Section 9.3 Time Limitations

      All  representations  and  warranties set out in this Agreement and in any
Ancillary  Agreement shall survive the Closing and,  notwithstanding the Closing
or any investigation made by or on behalf of the Purchaser or the Vendors, shall
continue  for a period of 24  months  after  the  Closing  Date and any claim in
respect thereof shall be made in writing during such time period.

Section 9.4 Limitations on Amount

(1)   The Corporation will have no liability (for  indemnification or otherwise)
      with respect to the matters  described in Section 9.2 other than to permit
      the  issuance  of the  additional  shares of the  Purchaser  as set out in
      Section 2.5(1)(b).

(2)   The Purchaser  will have no liability (for  indemnification  or otherwise)
      with  respect  to the  matters  described  in  Section  9.2 other than the
      covenant to issue additional shares set out in Section 2.5(1)(a).

Section 9.5 Procedure for Indemnification--Third Party Claims.

(1)   Promptly after receipt by an indemnified  party (an  "Indemnified  Party")
      under  Section 9.1 or Section 9.2 of a notice of the  commencement  of any
      proceeding  against it, the  Indemnified  Party will,  if a claim is to be
      made against an indemnifying party under such Section,  give notice to the
      Indemnifying  Party (an "Indemnifying  Party") of the commencement of such
      claim. The failure to notify the  Indemnifying  Party will not relieve the
      Indemnifying  Party of any liability  that it may have to any  Indemnified
      Party,  except to the extent that the Indemnifying Party demonstrates that
      the  defence  of such  action is  prejudiced  by the  Indemnified  Party's
      failure to give such notice.

                                      -52-
<PAGE>

(2)   If any  proceeding  referred  to in  Section  9.5(1) (a  "Proceeding")  is
      brought  against  an  Indemnified   Party  and  it  gives  notice  to  the
      Indemnifying Party of the commencement of the Proceeding, the Indemnifying
      Party will, unless the claim involves taxes, be entitled to participate in
      the Proceeding. Subject to the next following sentence, to the extent that
      the Indemnifying Party wishes to assume the defence of the Proceeding with
      counsel  satisfactory to the  Indemnified  Party, it may do so provided it
      reimburses the  Indemnified  Party for all of its  out-of-pocket  expenses
      arising prior to or in connection with such  assumption.  The Indemnifying
      Party may not assume  defence of the  Proceeding  if (i) the  Indemnifying
      Party  is  also a  party  to the  Proceeding  and  the  Indemnified  Party
      determines in good faith that joint representation would be inappropriate,
      or (ii) the Indemnifying  Party fails to provide  reasonable  assurance to
      the Indemnified  Party of its financial  capacity to defend the Proceeding
      and provide  indemnification with respect to the Proceeding.  After notice
      from the  Indemnifying  Party to the Indemnified  Party of its election to
      assume the defence of the Proceeding,  the Indemnifying Party will not, as
      long as it diligently  conducts such defence, be liable to the Indemnified
      Party under this  Section  9.5 for any fees of other  counsel or any other
      expenses  with  respect  to the  defence of the  Proceeding,  in each case
      subsequently  incurred by the  Indemnified  Party in  connection  with the
      defence of the Proceeding,  other than reasonable  costs of  investigation
      approved in advance by the Indemnifying  Party. If the Indemnifying  Party
      assumes the defence of a  Proceeding,  no compromise or settlement of such
      claims  may be made by the  Indemnifying  Party  without  the  Indemnified
      Party's  consent  unless  (i)  there is no  finding  or  admission  of any
      violation  of Laws or any  violation  of the  rights of any  Person and no
      effect on any other claims that may be made against the Indemnified Party,
      and (ii) the sole relief  provided is  monetary  damages  that are paid in
      full by the Indemnifying  Party, and (iii) the Indemnified Party will have
      no liability  with respect to any  compromise or settlement of such claims
      effected without its consent.  If notice is given to an Indemnifying Party
      of the commencement of any Proceeding and the Indemnifying Party does not,
      within  ten  days  after  receipt  of  such  notice,  give  notice  to the
      Indemnified Party of its election to assume the defence of the Proceeding,
      the  Indemnifying  Party  will be bound by any  determination  made in the
      Proceeding or any  compromise or  settlement  effected by the  Indemnified
      Party.

(3)   Notwithstanding the foregoing,  if an Indemnified Party determines in good
      faith  that  there  is a  reasonable  probability  that a  Proceeding  may
      adversely  affect it or its affiliates  other than as a result of monetary
      damages  for which it would be  entitled  to  indemnification  under  this
      Agreement, the Indemnified Party may, by notice to the Indemnifying Party,
      assume  the  exclusive  right  to  defend,   compromise,   or  settle  the
      Proceeding.  In such case, the Indemnifying Party will not be bound by any
      determination  of a Proceeding so defended or any compromise or settlement
      effected without its consent (which may not be unreasonably withheld).

                                      -53-
<PAGE>

(4)   Where the defence of a Proceeding is being  undertaken  and  controlled by
      the  Indemnifying  Party,  the  Indemnified  Party will use all reasonable
      efforts to make available to the Indemnifying  Party those employees whose
      assistance,  testimony or presence is necessary to assist the Indemnifying
      Party  in  evaluating  and  defending  any  such  claims.   However,   the
      Indemnifying  Party shall be responsible  for the expense  associated with
      any employees made available by the Indemnified  Party to the Indemnifying
      Party pursuant to this Section 9.5(4),  which expense shall be equal to an
      amount to be mutually  agreed upon per person per hour or per day for each
      day or portion  thereof that the employees are assisting the  Indemnifying
      Party  and  which  expenses  shall  not  exceed  the  actual  cost  to the
      Indemnified Party associated with the employees.

(5)   With respect to any Proceeding, the Indemnified Party shall make available
      to the  Indemnifying  Party or its  representatives  on a timely basis all
      documents,   records  and  other   materials  in  the  possession  of  the
      Indemnified  Party, at the expense of the Indemnifying  Party,  reasonably
      required by the Indemnifying Party for its use in defending any such claim
      and shall  otherwise  cooperate  on a timely  basis with the  Indemnifying
      Party in the defence of such claim.

(6)   With respect to any re-assessment for income, corporate, sales, excise, or
      other tax or other  liability  enforceable by Lien against the property of
      the Indemnified Party, the Indemnifying  Party's right to so contest shall
      only apply after  payment of the  re-assessment  or the  provision of such
      security as is  necessary  to avoid a Lien being placed on the property of
      the Indemnified Party.

Section 9.6 Procedure for Indemnification--Other Claims

      A claim for  indemnification  for any matter not  involving a  third-party
claim  may be  asserted  by notice to the  Party  from whom  indemnification  is
sought.

                             POST-CLOSING COVENANTS

Section 10.1 Further Assurances

      From time to time after the Closing Date, each Party shall, at the request
of any other Party, execute and deliver such additional  conveyances,  transfers
and other assurances as may be reasonably  required to effectively  transfer the
Purchased Shares to the Purchaser and carry out the intent of this Agreement and
any Ancillary  Agreement.  In addition,  the parties shall reasonably  cooperate
with each other in the  preparation  and filing of a Current  Report on Form 8-K
with the SEC reporting on the transactions contemplated by this Agreement within
the time periods specified by such Report.

Section 11.9 Entire Agreement

      This  Agreement  together with the Ancillary  Agreements  constitutes  the
entire  agreement  between  the  Parties and  supersedes  all prior  agreements,
understandings,  negotiations and discussions,  whether oral or written,  of the
Parties.  There are no  representations,  warranties,  covenants,  conditions or
other  agreements,  express or  implied,  collateral,  statutory  or  otherwise,
between the Parties in  connection  with the  subject  matter of this  Agreement
except as specifically  set forth herein and therein and neither the Vendors nor
the Purchaser has relied or is relying on any other  information,  discussion or
understanding in entering into and completing the  transactions  contemplated in
this  Agreement  and the  Ancillary  Agreements.  If  there is any  conflict  or
inconsistency between the provisions of this Agreement and the provisions of any

      and permitted assigns.

(2)   Except as provided in this Section  11.10,  neither this Agreement nor any
      of the rights or obligations  under this Agreement  shall be assignable or
      transferable  by any Party without the prior written  consent of the other
      Party. The Purchaser shall be entitled,  upon giving notice to the Vendors
      at any time on or prior to the Closing Date,  to assign this  Agreement or
      any of the Purchaser's  rights and obligations under this Agreement to any
      affiliate  (as such term is defined  under the Business  Corporations  Act
      (Alberta)) of the Purchaser subject to the following three conditions:

      (a)   The assignee  shall  become  jointly and  severally  liable with the
            Purchaser,  as a principal and not as a surety,  with respect to all
            of  the  representations,  warranties,  covenants,  indemnities  and
            agreements of the Purchaser; and

      (b)   The assignee  shall execute an agreement  confirming  the assignment
            and  the  assumption  by  the  assignee  of all  obligations  of the
            Purchaser under this Agreement.

Section 11.11 Severability

      If any provision of this Agreement shall be determined by an arbitrator or
any court of competent  jurisdiction  to be illegal,  invalid or  unenforceable,
that provision shall be severed from this Agreement and the remaining provisions

BETWEEN:

            GOLDSTRIKE INC.

            GRAN TIERRA GOLDSTRIKE INC.
            Incorporated under the laws of the Province of Alberta
            (herein called "ExchangeCo")

WHEREAS:

A.    Goldstrike  is a  party  to  a  share  purchase  agreement  (the  "Assumed
      Contract")  dated  November 10, 2005 among Gran Tierra Energy Inc.  ("Gran
      Tierra"),  the vendors  named in the  Assumed  Contract,  as vendors,  and

B.    Goldstrike wishes to assign and ExchangeCo  wishes to assume  Goldstrike's
      rights and obligations under the Assumed Contract  effective  November 10,

      WITNESSES THAT in consideration of the mutual covenants  contained in this
Agreement and other good and valuable consideration (the receipt and sufficiency

1.    ASSIGNMENT OF ASSUMED CONTRACT

            with full power and  authority to demand or sue for  performance  of
            the  Covenants,  in the  name of  Goldstrike,  but at the  cost  and
            expense of ExchangeCo.

<PAGE>
                                      -2-

      1.2.  ExchangeCo   hereby  assumes  the  obligations  and  liabilities  of
            Goldstrike  under the Assumed  Contract  arising or to be  performed
            from and after the Effective Date,  including but not limited to all
            covenants  of  confidentiality,  and  agrees to  indemnify  and save
            harmless  Goldstrike  with respect to all Damages (as defined in the
            Assumed  Contract)  arising from or in connection with, or resulting
            from, any breach or  non-observance  by ExchangeCo or those for whom
            it is  responsible  in law, from and after the Effective Date of any
            of  ExchangeCo's  obligations  and  liabilities  under  the  Assumed
            Contract.

      1.3.  Without limiting paragraph 1.2,  ExchangeCo confirms and agrees that
            from the Effective Date it shall be liable as a principal and not as
