as an officer or director may no longer hold office at the date of the Special
Warrant Certificate or at the date of certification or delivery thereof, any
Special Warrant Certificate signed as aforesaid shall, subject to section 2.8,
be valid and binding upon the Company.

2.8  Certification by the Trustee or Co-transfer Agent

     (1) The Trustee shall certify Special Warrant Certificates upon the
written direction of the Company. No Special Warrant Certificate shall be
issued or, if issued, shall be valid or entitle the holder to the benefit
hereof until it has been certified by manual signature by or on behalf of the
Trustee, or by manual signature by the Co-transfer Agent, substantially in the
form approved by the Company and the Trustee and the certification by the
Trustee or by the Co-transfer Agent upon any Special Warrant Certificate shall
be conclusive evidence as against the Company that the Special Warrant
Certificate so certified has been duly issued hereunder and that the holder is
entitled to the attributes and characteristics of the Special Warrants provided
for in this Indenture.

     (2) The certification of the Trustee or of the Co-transfer Agent on
Special Warrant Certificates issued hereunder shall not be construed as a
representation or warranty by the Trustee or by the Co-transfer Agent as to the
validity of this Indenture or of the Special Warrant Certificates (except the
due certification thereof) and the Trustee or the Co-transfer Agent shall in no
respect be liable or answerable for the use made of the Special Warrants or any
of them or of the consideration therefor, except as otherwise specified herein.

                   Exchange and Ownership of Special Warrants

3.1  Exchange of Special Warrants

     (1) Upon the request of a Special Warrantholder one or more Special
Warrant Certificates may, upon compliance with the reasonable requirements of
the Trustee, be exchanged for one or more Special Warrant Certificates of
different denominations evidencing, in the aggregate, the same number of
Special Warrants





                                     - 12 -
   17
as the Special Warrant Certificate or Special Warrant Certificates being
exchanged and shall bear the same legends as the Special Warrant Certificates
being exchanged.

     (2) Special Warrants may be exchanged only at the principal transfer
offices of the Trustee in either of the Cities of Toronto or Vancouver or at
the principal transfer office of the Co-transfer Agent designated by the
Company or at any other place that is designated by the Company with the
approval of the Trustee. Any Special Warrant Certificates tendered for exchange
shall be surrendered to the Trustee or to its agent or the Co-transfer Agent
and, upon issuance of new Special Warrants in exchange therefor, cancelled. The
Company shall sign all Special Warrant Certificates necessary to carry out
exchanges as aforesaid and those Special Warrant Certificates shall be
certified by or on behalf of the Trustee.

3.2  Charges for Exchange or Transfer

     For each Special Warrant transferred or Special Warrant Certificate
exchanged, other than on the exchange by the Underwriters of a global
certificate representing all Special Warrants and the transfer of all such
Special Warrants by the Underwriters, the Trustee, or the Co-transfer Agent
except as otherwise herein provided, shall charge if required by the Company a
reasonable sum in respect of each Special Warrant transferred or Special
Warrant Certificate exchanged. The party requesting the transfer or exchange,
as a condition precedent thereto, shall pay such charges and shall pay or
reimburse the Trustee, the Co-transfer Agent or the Company for all exigible
transfer taxes or governmental or other similar transfer charges required to be
paid in connection therewith.

3.3  Ownership of Special Warrants

     The Company and the Trustee and their respective agents may deem and treat
the holder of any Special Warrant as the absolute owner of that Special Warrant
for all purposes, and the Company and the Trustee and their respective agents
shall not be affected by any notice or knowledge to the contrary except as
required by statute or by order of a court of competent jurisdiction. The
holder of any Special Warrant shall be entitled to the rights evidenced by that
Special Warrant free from all equities or rights of set-off or counterclaim
between the Company and the original or any intermediate holder thereof and all
persons may act accordingly and the receipt from any holder for the Shares,
Warrants or monies obtainable pursuant thereto shall be a good discharge to the
Company and the Trustee for the same and neither the Company nor the Trustee
shall be bound to inquire into the title of any such registered holder.

3.4  Registration and Transfer of Special Warrants

     (1) The Company hereby appoints the Trustee as Registrar of the Special
Warrants. The Company may hereafter, with the consent of the Trustee, appoint
one or more other additional Registrars of the Special Warrants, including any
Co-transfer Agent.

     (2) The Company shall cause a register to be kept by the Trustee, and the
Trustee agrees to maintain such a register, at its principal transfer office in
the City of Vancouver, in which shall be entered alphabetically the names and
addresses of the holders of Special Warrants and other particulars of the
Special Warrants held by them respectively and a register of all transfers of
Special Warrants and the date and other particulars of each transfer. Such
registration shall be noted on the Special Warrant Certificates by the Trustee
or other Registrar duly appointed pursuant to subsection 3.4(1). The Company
shall also cause transfer agencies (each a "Transfer Agency") to be maintained
by the Trustee, and the Trustee shall maintain such Transfer Agencies at its
principal transfer offices in the Cities of Toronto and Vancouver and in such
other place or places and by such other agent as the Company with the approval
of the Trustee may designate.

     (3) No transfer of a Special Warrant shall be valid unless made on any one
of the registers upon surrender of the Special Warrant Certificate to the
Trustee or other Registrar duly appointed pursuant to subsection 3.4(1)
accompanied by a written instrument of transfer in form satisfactory to the
Trustee or other Registrar duly appointed pursuant to subsection 3.4(1)
executed by the registered holder or his executors, administrator or other
legal representatives or his attorney duly appointed by an instrument in
writing in form and execution satisfactory to the Trustee or other Registrar
duly appointed pursuant to subsection 3.4(1) and upon compliance with such
reasonable requirements as the Trustee or other Registrar duly appointed
pursuant to subsection 3.4(1) may prescribe, nor shall a transfer of a Special
Warrant be valid, except in the case where a new Special Warrant Certificate is
issued upon a transfer, unless the transfer shall have been noted on the
Special Warrant Certificate by the Trustee or other Registrar duly appointed
pursuant to subsection 3.4(1), provided however and notwithstanding the
provisions of this subsection 3.4(3), an Underwriter shall be entitled to be
entered on any one of the registers as the holder of Special Warrants evidenced
by a particular Special Warrant Certificate upon delivery by that Underwriter
to the Trustee of:

     (a)  the particular Special Warrant Certificate; and

     (b)  a certificate of that Underwriter to the effect that the purchaser of
          the Special Warrants evidenced by the particular Special Warrant
          Certificate has declined or refused to accept delivery of, and make
          payment for, the Special Warrants evidenced by the particular Special
          Warrant Certificate in accordance with the subscription





                                     - 14 -
   19
          or purchase agreement between such purchaser, the Company and
          ScotiaMcLeod Inc. (and ScotiaMcLeod (USA) Inc. in the case of a
          United States purchaser).

     (4) The registers referred to in this section 3.4 shall at all reasonable
times be open for inspection by the Company, by the Trustee and by any Special
Warrantholder.

     (5) The registered holder of a Special Warrant may at any time and from
time to time have the registration of the Special Warrant transferred from the
register in which the registration thereof appears to another authorized
register upon compliance with such reasonable requirements as the Trustee or
other Registrar duly appointed pursuant to subsection 3.4(1) may prescribe.

     (6) Subject to subsections 3.4(7), 3.4(8) and 3.4(9), the holder of a
Special Warrant may at any time and from time to time have the Special Warrant
transferred at any Transfer Agency in accordance with the conditions herein,
such reasonable requirements as the trustee or other Registrar duly appointed
pursuant to subsection 3.4(1) may prescribe and all applicable securities
legislation and requirements of regulatory authorities, provided however that
the transfer of Special Warrants shall be accompanied by a transfer form in the
form set forth in Schedule C hereto.

     (7) If the Special Warrant Certificate tendered for transfer bears the
U.S. Legend, the Trustee or other Registrar shall authenticate, register and
deliver in the name of the transferee a new Special Warrant Certificate,
representing the number of Special Warrants so transferred, bearing the U.S.
Legend; provided, that if the Special Warrants are being sold in accordance
with Rule 904 of Regulation S and the transferor has delivered to the Trustee
or other Registrar a declaration substantially in the form set forth in
Schedule D attached hereto, the Trustee or other Registrar shall authenticate,
register and deliver in the name of the transferee a new Special Warrant
Certificate, representing the Special Warrants so transferred, without the U.S.
Legend and, provided, further, that if the Special Warrants are being sold
pursuant to Rule 144 under the U.S. Securities Act and the transferor has
delivered to the Trustee or other Registrar an opinion of counsel, of
recognized standing reasonably satisfactory to the Company, to the effect that
the U.S. Legend is no longer required under applicable requirements of the U.S.
Securities Act or state securities laws, then the Trustee or other Registrar
shall authenticate, register and deliver in the name of the transferee a new
Special Warrant Certificate, representing the number of Special Warrants so
transferred, without the U.S. Legend.

     (8) Except as required by law, neither the Trustee nor any other Registrar
duly appointed pursuant to subsection 3.4(1) nor the Company shall be charged
with notice of or be bound to see to the execution of any trust, whether
express, implied or constructive, in respect of any Special Warrant and may
transfer any Special Warrant on the written direction of the person





                                     - 15 -
   20
registered as the holder thereof, whether named as trustee or otherwise, as
though that person were the beneficial owner thereof.

     (9) The registers required to be kept at the Cities of Vancouver and
Toronto shall not be closed at any time. In the event that an office of the
Transfer Agent or a Co-transfer Agent in any place is closed, notice of the
closing shall be given, in the manner provided in section 11.2, to the Special
Warrantholders.

     (10) The Trustee and every Registrar duly appointed pursuant to subsection
3.4(1) shall from time to time, when requested so to do by the Company, by the
Trustee or by any Special Warrantholder, furnish the Company, the Trustee or,
upon payment by the Special Warrantholder of a reasonable fee, the Special
Warrantholder, as the case may be, with a list of names and addresses of the
holders of Special Warrant entered on the register kept by such Trustee or
Registrar showing the number of Special Warrants held by each such holder.

                                     - 18 -
   23
exercise the right thereby conferred to acquire Shares and Warrants by
surrendering to the Trustee at its principal transfer offices in either of the
Cities of Toronto and Vancouver or at any other place or places that may be
designated by the Company with the approval of the Trustee, or to the
Co-transfer Agent at its principal transfer office designated by the Company, a
Special Warrant Certificate or Special Warrant Certificates representing the
Special Warrants held by such holder that are to be exercised, together with a

only be deemed to have been surrendered upon personal delivery thereof to, or
if sent by mail or other means of transmission upon actual receipt thereof by,
the Trustee or the Co-transfer Agent at one of the offices specified in this
section.

     (2) Any exercise form delivered pursuant to subsection 4.6(1) shall be
signed by the Special Warrantholder or the Special Warrantholder's executors or

Shares and Warrants to be issued upon exercise are to be issued, the person's
or persons' address or addresses and the number of Shares and Warrants to be
issued to each person if more than one is so specified. If any of the Shares
and Warrants to be acquired are to be issued to a person or persons other than
the Special Warrantholder, the Special Warrantholder shall pay to the Trustee
or to its agent all exigible transfer taxes or governmental or other charges
required to be paid in respect of the transfer of the Special Warrants or
Shares or Warrants and the Company will not be required to issue or deliver any
certificate evidencing any Shares or Warrants unless or until that amount has
been so paid or the Special Warrantholder has established to the satisfaction
of the Company that the taxes and charges have been paid or that no taxes or
charges are owing.

     (3) If, at the time of exercise of the Special Warrants, there remain
restrictions on resale under applicable securities legislation on the Shares
and Warrants acquired, the Company may, on the advice of counsel, endorse the
certificates representing the Shares and Warrants with respect to those
restrictions.

4.7  Effect of Exercise of Special Warrants

     (1) Upon the exercise or deemed exercise of any Special Warrants and

     (a)  one-half Warrant for each Special Warrant exercised; and





                                     - 19 -
   24
     (b)  the number of Shares that is equal to the number of Special Warrants
          exercised multiplied by the Exchange Number in effect at the Exercise
          Date,

and the Company shall cause the holder thereof to be entered forthwith on its
register of shareholders as the holder of the Shares and on the register of
Warrantholders as the holder of the Warrants and the Shares and Warrants so
acquired shall be deemed to have been issued, and the person or persons to whom
those Shares and Warrants are to be issued shall be deemed to have become the
shareholder or shareholders of record of the Shares and the Warrantholder or
registered Warrantholder of the Warrants on the Exercise Date unless the
register of the Company or the register of Warrantholders shall be closed on
that date, in which case the Shares and Warrants so acquired shall be deemed to
be issued and the person or persons shall be deemed to become the holder or
holders of record thereof on the date or dates on which the registers are
reopened and the Shares and Warrants shall be issued on the later date or
dates.

     (2) Upon the exercise or deemed exercise of the Special Warrants as
aforesaid, the Company shall, without charge therefor except as provided in
subsection 4.6(2), forthwith cause to be delivered to the Trustee as agent for,
upon exercise pursuant to section 4.6 the person or persons in whose name or
names the Shares and Warrants so acquired are to be issued as specified in the
exercise form attached to the Special Warrant Certificate, or upon deemed
exercise pursuant to section 4.10 the holder of the Special Warrants deemed
exercised certificates for the appropriate number of Shares and Warrants that
the Special Warrantholder is entitled to and has elected to acquire pursuant to
the Special Warrants exercised. Upon receipt by the Trustee of such
certificates the Trustee shall cause such certificates to be delivered
forthwith in accordance with the written delivery instructions of the holder,
or in the absence of such instructions, by registered mail without charge
therefor, to the person or persons in whose name or names the Shares and
Warrants have been issued at the addresses specified in, upon exercise pursuant
to section 4.6 the exercise form, or upon deemed exercise pursuant to section
4.10 the register for the Special Warrants deemed exercised, and if the
Qualification Date has occurred, a copy of the Final Prospectus, unless a copy
thereof has previously been given by the Company to such person or persons.

4.8  Partial Exercise of Special Warrants

     Except as provided for in section 4.10 and paragraph 4.4(1)(b), a Special
Warrantholder may exercise any number of Special Warrants up to the aggregate
number of Special Warrants represented by the Special Warrant Certificate
surrendered. In the event of any exercise of a number of Special Warrants less
than the number which the holder is entitled to exercise, the holder of the
Special Warrants upon such exercise shall be entitled to receive, without
charge therefor, a new Special Warrant Certificate in respect of the balance of
the





                                     - 20 -
   25
Special Warrants represented by the surrendered Special Warrant Certificate and
which were not then exercised and the Trustee shall issue a new Special Warrant
Certificate upon surrender of such Special Warrant Certificate, if satisfied
that the new Special Warrant Certificate is properly issuable.

4.9  No Fractional Shares or Warrants

     Notwithstanding anything herein contained including any adjustment
provided for in Article Five, the Company shall not be obliged to issue any
fractional Shares or Warrants or to distribute certificates which evidence
fractional Shares or Warrants upon the exercise of one or more Special
Warrants. To the extent that the holder of one or more Special Warrants would
otherwise have been entitled to receive on the exercise or partial exercise
thereof a fraction of a Share or Warrant that holder may exercise that right in
respect of the fraction only in combination with other Special Warrants that in
the aggregate entitle the holder to purchase a whole number of Shares and
Warrants. If not so exercised, the Company shall not pay any amounts to the
holder in satisfaction of the right to otherwise have received a fraction of a
Share or Warrant.

4.10 Deemed Exercise of Special Warrants

     Immediately prior to the expiry of the Exercise Period, all Special
Warrants not exercised by the holders thereof in accordance with section 4.6
and not retracted in accordance with section 4.4 shall be deemed to have been
then exercised and surrendered by the holder without any further action on the
part of the holder.

4.11 Accounting and Recording

     The Trustee shall record the particulars of the Special Warrants
exercised, including the name or names and addresses of the persons who become
holders of Shares and Warrants on exercise and the Exercise Date. Within three
business days of each Exercise Date, the Trustee shall provide those
particulars in writing to the Company.

4.12 Cancellation of Surrendered Special Warrants

     All Special Warrant Certificates surrendered to the Trustee shall be
cancelled by the Trustee and, upon request therefor by the Company, the Trustee
shall furnish the Company with a certificate identifying the Special Warrant
Certificates so cancelled and the number of Shares and Warrants which have been
issued pursuant to each.

4.13 Exercise Restrictions

     Notwithstanding the foregoing, Special Warrant Certificates bearing the
U.S. Legend may only be exercised pursuant

               outstanding on the record date before giving effect to the Share
               Reorganization.

For the purposes of determining the number of Shares outstanding at any
particular time for the purpose of this subsection 5.2(1) there shall be
included that number of Shares which would have resulted from the conversion at
that time of all outstanding Convertible Securities (which, for greater
certainty, includes Warrants issued prior to the end of the Exercise Period,
pursuant to the exercise of Special Warrants).

     (2) If during the Exercise Period the Company shall issue rights, options
or warrants (other than the Warrants) to all or substantially all the holders
of the Shares pursuant to which those holders are entitled to subscribe for,
purchase or otherwise acquire Shares or Convertible Securities within a period
of 45 days from the date of issue thereof at a price per share, or at a
conversion price per share, of less than 95% of the Current Market Price at the
record date for such distribution (any such issuance being herein called a
"Rights Offering" and Shares that may be acquired in exercise of the Rights
Offering, or upon conversion of





                                     - 23 -
   28
the Convertible Securities offered by the Rights Offering, being herein called
the "Offered Shares"), the Exercise Number shall be adjusted effective
immediately after the record date at which holders of Shares are determined for
the purposes of the Rights Offering to an Exercise Number that is the product
of (1) the Exercise Number in effect on the record date and (2) a fraction:

          (i)  the numerator of which shall be the sum of (a) the number of
               Shares outstanding on the record date plus (b) the number of
               Offered Shares offered pursuant to the Rights Offering or the
               maximum number of Offered Shares into which the Convertible
               Securities so offered pursuant to the Rights Offering may be
               converted, as the case may be; and

          (ii) the denominator of which shall be the sum of:

               (A)  the number of Shares outstanding on the record date; and

               (B)  the number arrived at when (I) either the product of (a)
                    the number of Offered Shares so offered and (b) the price
                    at which those shares are offered, or the product of (c)
                    the conversion price thereof and (d) the maximum number of
                    Offered Shares for or into which the Convertible Securities
                    so offered pursuant to the Rights Offering may be
                    converted, as the case may be, is divided by (II) the
                    Current Market Price of the Shares on the record date.

Any Offered Shares owned by or held for the account of the Company or a
subsidiary of the Company shall be deemed not to be outstanding for the purpose
of any such computation; if all the rights, options or warrants are not so
issued or if all rights, options or warrants are not exercised prior to the
expiration thereof, the Exercise Number shall be readjusted to the Exercise
Number in effect immediately prior to the record date, and the Exercise Number
shall be further adjusted based upon the number of Offered Shares (or
Convertible Securities that are convertible into Offered Shares) actually
delivered upon the exercise of the rights, options or warrants, as the case may
be, but subject to any other adjustment required hereunder by reason of any
event arising after that record date.

     (3) If during the Exercise Period the Company shall issue or distribute to
all or substantially all the holders of Shares, (i) shares of any class other
than Shares, or (ii) rights, options or warrants other than Warrants and other
than rights, options or warrants exercisable within 45 days from the date of
issue thereof at a price, or at a conversion price, of at least 95% of the





                                     - 24 -
   29
Current Market Price at the record date for such distribution, or (iii)
evidences of indebtedness, or (iv) any other cash, securities or other property
or assets (excluding cash dividends that Special Warrantholders receive under
section 6.5) and that issuance or distribution does not constitute a Share
Reorganization or a Rights Offering (any of those events being herein called a
"Special Distribution"), the Exercise Number shall be adjusted effective
immediately after the record date at which the holders of Shares are determined
for purposes of the Special Distribution to an Exercise Number that is the
product of (1) the Exercise Number in effect on the record date and (2) a
fraction:

          (i)  the numerator of which shall be the product of (I) the sum of
               the number of Shares outstanding on the record date plus the
               number of Shares which the Special Warrantholders would be
               entitled to receive upon exercise of all their outstanding
               Special Warrants if they were exercised on the record date and
               (II) the Current Market Price thereof on that date; and

          (ii) the denominator of which shall be:

               (A)  the product of (I) the sum of the number of Shares
                    outstanding on the record date plus the number of Shares
                    which the Special Warrantholders would be entitled to
                    receive upon exercise of all their outstanding Special
                    Warrants if they were exercised on the record date and (II)
                    the Current Market Price thereof on the earlier of such
                    record date and the date on which the Company announces its
                    intention to make such distribution;

               less 

               (B)  the aggregate fair market value, as determined by the board
                    at the time such distribution is authorized, whose
                    determination shall be conclusive, of the shares, rights,
                    options, warrants, evidences of indebtedness or other
                    assets issued or distributed in the Special Distribution.

Any Shares owned by or held for the account of the Company shall be deemed not
to be outstanding for the purpose of any such computation; to the extent that
the distribution of shares, rights, options, warrants, evidences of
indebtedness or assets is not so made or to the extent that any rights, options
or warrants so distributed are not exercised, the Exercise Number shall be
readjusted to the Exercise Number that would then be in effect based upon
shares, rights, options, warrants, evidences of





                                     - 25 -
   30
indebtedness or assets actually distributed or based upon the number of Shares
or Convertible Securities actually delivered upon the exercise of the rights,
options or warrants, as the case may be, but subject to any other adjustment
required hereunder by reason of any event arising after the record date.

     (4) If during the Exercise Period there is a reorganization of the Company
not otherwise provided for in subsection 5.2(1) or a consolidation or merger or
amalgamation of the Company with or into another body corporate including a
transaction whereby all or substantially all of the Company's undertaking and
assets become the property of any other corporation through sale, lease,
exchange or otherwise (any such event being herein called a "Capital
Reorganization") any holder of a Special Warrant who has not exercised his
right to exchange his Special Warrant for Shares and Warrants prior to the
effective date of the Capital Reorganization shall be entitled to receive and
shall accept, upon the exercise of his right at any time after the effective
date of the Capital Reorganization, in lieu of the number of Shares and
Warrants (and any other securities or properties to which holders are entitled
upon exercise of the Special Warrants) to which he was theretofore entitled
upon exercise of the Special Warrant, the aggregate number of shares or other
securities or property of the Company, or the continuing, successor or
purchasing corporation, as the case may be, under the Capital Reorganization
that the holder would have been entitled to receive as a result of the Capital
Reorganization if, on the effective date thereof, he had been the holder of the
number of Shares and Warrants (and any other securities to which holders are
entitled upon exercise of the Special Warrants) to which immediately before the
transaction he was entitled upon exercise of the Special Warrants; no Capital
Reorganization shall be carried into effect unless all necessary steps shall
have been taken so that the holders of Special Warrants shall thereafter be
entitled to receive the number of shares or other securities or property of the
Company, or of the continuing, successor or purchasing corporation, as the case
may be, under the Capital Reorganization, subject to adjustment thereafter in
accordance with provisions the same, as nearly as may be possible, as those
contained in this section 5.2 and in section 5.3.

     (5) If the Company shall reclassify or otherwise change the outstanding
Shares, the exercise right shall be adjusted effective immediately upon the
reclassification becoming effective so that holders of Special Warrants who
exercise their rights thereafter shall be entitled to receive such shares as
they would have received had the Special Warrants been exercised immediately
prior to the effective date, subject to adjustment thereafter in accordance
with provisions the same, as nearly as may be possible, as those contained in
this section 5.2 and in section 5.3.

5.3  Subscription Rights Adjustment Rules

     The following rules and procedures shall be applicable to adjustments made
pursuant to section 5.2:





                                     - 26 -
   31
     (1) The adjustments and readjustments provided for in this Article Five
are cumulative and, subject to subsection 5.3(2), shall apply (without
duplication) to successive issues, subdivisions, combinations, consolidations,
distributions and any other events that require adjustment of the Exercise
Number or the number or kind of shares or securities purchasable hereunder.

     (2) No adjustment in the Exercise Number shall be required unless the
adjustment would result in a change of at least 1% in the Exercise Number then
in effect provided, however, that any adjustments that, except for the
provisions of this subsection 5.3(2) would otherwise have been required to be
made, shall be carried forward and taken into account in any subsequent
adjustment.

     (3) No adjustment in the Exercise Number shall be made in respect of any
event described in paragraph 5.2(l)(a) or subsections 5.2(2) or 5.2(3) if the
holders of the Special Warrants are entitled to participate in the event on the
same terms, mutatis mutandis, as if they had exercised their Special Warrants
immediately prior to the effective date or record date of the event.

     (4) No adjustment in the Exercise Number shall be made pursuant to section
5.2 in respect of the issue of Shares, rights, options or warrants pursuant

     (a)  to this Indenture;

     (b)  the issuance of Shares pursuant to the exercise of directors,
          officers and employees options or options granted for services in
          accordance with the rules of The Toronto Stock Exchange;

     (c)  the issuance of Shares pursuant to the exercise of Warrants (except
          that the number of Convertible Securities will increase if Warrants
          are issued prior to the end of the Exercise Period); or

     (d)  the issuance of any special warrants to L.B. Mining Co. or any
          affiliate thereof in part consideration for the acquisition of the
          Guariche property in Venezuela, the issuance of any Shares pursuant
          to the exercise of such special warrants, the issuance of any common
          share purchase warrants pursuant to the exercise of such special
          warrants, and the issuance of any Shares pursuant to the exercise of
          such common share purchase warrants (except that the number of
          Convertible Securities will increase if such common share purchase
          warrants are issued prior to the expiry of their exercise period);

and any such issue shall be deemed not to be a Share Reorganization, a Rights
Offering or a Special Distribution.





                                     - 27 -
   32
     (5) If a dispute shall at any time arise with respect to adjustments of
the Exercise Number, the dispute shall be conclusively determined (as between
the Company, the Special Warrantholders, the Trustee and all transfer agents
and shareholders of the Company) by the auditors of the Company or if they are
unable or unwilling to act, by such firm of independent chartered accountants
as may be selected by the directors and any such determination shall be binding
upon the Company, the Special Warrantholders, the Trustee and all transfer
agents and shareholders of the Company.

     (6) If the Company shall set a record date to determine the holders of
Shares for the purpose of entitling them to receive any dividend or
distribution or any subscription or purchase rights and shall, thereafter
legally abandon its plans to pay or deliver the dividend, distribution or
subscription or purchase rights, then no adjustment in the Exercise Number
shall be required by reason of the setting of the record date.

5.4  Postponement of Subscription

     In any case where the application of section 5.2 results in an increase of
the Exercise Number taking effect immediately after the record date for or
occurrence of a specific event, if any Special Warrants are exercised after
that record date or occurrence and prior to completion of the event or of the
period for which a calculation is required to be made, the Company may postpone
the issuance to the holder of the Special Warrants of the Shares to which the
holder is entitled by reason of the increase of the Exercise Number but the
Shares shall be so issued and delivered to that holder upon completion of that
event or period, with the number of those Shares calculated on the basis of the
Exercise Number on the Exercise Date adjusted for completion of that event or
period, and the Company shall forthwith after the Exercise Date deliver to the
person or persons in whose name or names the Shares are to be issued an
appropriate instrument evidencing the person's or persons' right to receive the
Shares.

5.5  Notice of Certain Events

     (1) Upon the occurrence of any event referred to in sections 5.2 or 5.3
that requires an adjustment in the Exercise Number, the Company shall promptly
thereafter:

     (a)  file with the Trustee a certificate of the Company specifying the
          particulars of the event and, if determinable, the adjustment and a
          computation of the adjustment; and

     (b)  give notice to the Special Warrantholders of the particulars of the
          event and, if determinable, the adjustment.





                                     - 28 -
   33
     (2) If notice has been given under subsection 5.5(1) and the adjustment is
not then determinable, the Company shall promptly after the adjustment is
determinable:

     (a)  file with the Trustee a certificate of the Company evidencing the
          computation of the adjustment; and

     (b)  give notice to the Special Warrantholders of the adjustment.

5.6  Protection of Trustee

     Subject to sections 10.2 and 10.3, the Trustee shall not at any time be
under any duty or responsibility to any Special Warrantholder to determine
whether any facts exist which may require any adjustment contemplated by
section 5.2, or with respect to the nature or extent of any such adjustment
when made, or with respect to the method employed in making the same.

5.7  Proceedings Prior to Any Action Requiring Adjustment

     As a condition precedent to the taking of any action which would require
an adjustment in any of the acquisition rights pursuant to any of the Special
Warrants, including the number of Shares which are to be received upon the
exercise of the Special Warrants, the Company shall take any corporate action
which may, in the opinion of counsel, be necessary in order that the Company
has unissued and reserved in its authorized capital and may validly and legally
issue as fully paid and non-assessable all the Shares which the holders of such
Special Warrants are entitled to receive on the full exercise thereof in
accordance with the provisions hereof.

          end of the Retraction Period to the Company in respect of the Special
          Warrants of Special Warrantholders who have not retracted their
          Special Warrants and who have exercised or are deemed to have
          exercised their Special Warrants pursuant to section 4.6 or 4.10 the
          monies specified in subsection 6.4(3).

     For purposes of the determination of proportionate shares of interest
earned in the hands of the Trustee to be paid under this section 6.4, the
determinations shall be based on the number of Special Warrants held by the
recipient at the time of the payment and the length of time the amount has been
on deposit for the benefit of the recipient, which in respect of any payment
payable in lieu of dividends shall be deemed to be from the date on which the
dividend was paid.

6.5  Right to Dividends or Distributions

     If during the period commencing on the date hereof and ending on the

all or substantially all of the holders of





                                     - 33 -
   38
Shares or if the Company declares any dividend, or provides for any
distribution, payable to all or substantially all the holders of Shares of
record during that period, Special Warrantholders who exercise or are deemed to
have exercised their Special Warrants shall be entitled to participate in the
dividend or distribution on the same terms, mutatis mutandis, as if they
exercised their Special Warrants immediately prior to the effective date or
record date of the dividend or distribution.  For cash dividends this
entitlement shall be satisfied, to the extent of any payment received under
section 6.4, without duplication, by the payment received under section 6.4.
For stock dividends or distributions in respect of which an adjustment can be
made in the Exercise Number pursuant to paragraph 5.2(1)(a) or subsections
5.2(2) or 5.2(3), this entitlement shall be satisfied by such an adjustment.

6.6  Investment of Funds

     Funds deposited hereunder with the Trustee shall, pending any payment out
thereof as required in accordance with section 6.4, be invested by the Trustee
in accordance with section 10.4 hereof.

6.7  Performance of Covenants by Trustee

     If the Company shall fail to perform any of its covenants and obligations
contained in this Indenture, the Trustee may notify the Special Warrantholders
of the failure on the part of the Company or may itself perform any of the said
covenants capable of being performed by it, but shall be under no obligation to
do so or to notify the Special Warrantholders. All sums expended or advanced by
the Trustee in so doing shall be repayable as provided in section 6.3. No
performance, expenditure or advance by the Trustee shall be deemed to relieve
the Company of any default or of its continuing obligations hereunder.

6.8  Certificate of the Company

     The Company shall deliver to the Trustee, on each exercise date and the
same date that it delivers either the Notice of Compliance or the Notice of
Non-Compliance to the Trustee, a certificate indicating the Exercise Number as
at that date and whether or not any dividends or distributions referred to in
section 6.5 have been made.

6.9  Rescission Right

     The Company covenants with the Trustee to provide a right of rescission to
each Special Warrantholder as hereinafter set forth, which right shall be
exercisable either by the Trustee on behalf of a Special Warrantholder or by a
Special Warrantholder directly:

     In the event that any holder of Special Warrants who acquires Shares and
     Warrants upon the exercise or deemed exercise of his Special





                                     - 34 -
   39
     Warrants is or becomes entitled under applicable securities legislation to
     the remedy of rescission by reason of the Final Prospectus or any
     amendment thereto containing a misrepresentation, such holder shall be
     entitled to rescission not only of such holder's exercise of such Special
     Warrants but also of the purchase of such Special Warrants hereunder, and
     shall be entitled in connection with such rescission to a full refund of
     all consideration paid to the Company on the acquisition of such Special
     Warrants. In the event such holder is a permitted assignee of the interest
     of the original purchaser of such Special Warrants, such permitted
     assignee shall be entitled to exercise the rights of rescission and refund
     granted hereunder as if such permitted assignee were such original
     purchaser. The foregoing is in addition to any other right or remedy
     available to a holder of the Special Warrants under section 114 of the
     Securities Act (British Columbia), section 130 of the Securities Act
     (Ontario) or a corresponding provision of other securities legislation or
     otherwise at law.

resort hereunder be had to, the private property of any of the past, present or

8.1  Right to Convene Meetings

     The Trustee may at any time and from time to time and shall on receipt of
a written request of the Company or of a Special Warrantholders' Request, and
upon being indemnified to its reasonable satisfaction by the Company or by one
or more of the Special Warrantholders signing the Special Warrantholders'
Request against the costs that may be incurred in connection with the calling

the event of the Trustee failing, within 15 days after receipt of the written
request of the Company or Special Warrantholders' Request and indemnity given

Warrantholders, as the case may be, may convene the meeting. Every meeting
shall be held in the City of Vancouver or at such other place as may be
approved or determined by the Trustee.

     At least 14 days' notice of any meeting shall be given to the Special
Warrantholders in the manner provided in section 11.2 and a copy of the notice
shall be sent by mail to the Trustee unless the meeting has been called by it,
and to the Company unless the meeting has been called by it. Each notice shall

8.3  Chairman

     A person (who need not be a Special Warrantholder) designated in writing
by the Trustee shall be chairman of the meeting, and if no person is so
designated, or if the person so designated is not present within 15 minutes
from the time fixed for the holding of the meeting, the Special Warrantholders
present in person or by proxy shall choose a person present to be chairman.

8.4  Quorum

     Subject to the provisions of section 8.12, at any meeting of the Special
Warrantholders a quorum shall consist of one or more Special Warrantholders
present in person or by proxy and holding in aggregate, at least 20% of the
aggregate number of Shares and Warrants that could be acquired pursuant to all
the then outstanding Special Warrants. If a quorum of the Special
Warrantholders shall not be present within half an hour from the time fixed for
holding a meeting, the meeting, if summoned by the Special Warrantholders
pursuant to a Special Warrantholders' Request, shall be dissolved; but, subject
to section 8.12, in any other case the meeting shall be adjourned to the same
day in the next week (unless that day is not a business day, in which event the
meeting shall be reconvened on the next day that is a business day) at the same
time and place and no notice of the adjournment need be given. At the adjourned
meeting the Special Warrantholders present in person or by proxy shall form a
quorum and may transact the business for which the meeting was originally
convened, notwithstanding that they may not be entitled to acquire at least 20%
of the aggregate number of Shares and Warrants that can be acquired pursuant to
all the then outstanding Special Warrants.

8.5  Power to Adjourn

     The chairman of any meeting at which a quorum of the Special
Warrantholders is present may, with the consent of the meeting, adjourn the
meeting and no notice of the adjournment need be given except such notice, if
any, as the meeting may prescribe.

8.6  Show of Hands

     Every question submitted to a meeting shall be decided in the first place
by a majority of the votes given on a show of hands except that votes on an
Extraordinary Resolution shall be given in the manner hereinafter provided. At
any meeting, unless a poll is duly demanded or required as herein provided, a
declaration by the chairman that a resolution has been carried or carried
unanimously or by a particular majority or lost or not carried by a particular
majority shall be conclusive evidence of the fact.

8.7  Poll

     On every Extraordinary Resolution, and on any other question submitted to
a meeting upon which a poll is directed by





                                     - 37 -
   42
the chairman or requested by one or more of the Special Warrantholders acting
in person or by proxy and holding in the aggregate not less than 5% of the
aggregate number of Shares and Warrants that could be acquired pursuant to all
the Special Warrants then outstanding, a poll shall be taken in such manner as
the chairman shall direct.  Questions other than an Extraordinary Resolution
shall be decided by a majority of the votes cast on a poll.  The results of a
poll shall be deemed to be the decision of the meeting at which the poll was
demanded and shall be binding on all Special Warrantholders.

8.8  Voting

     On a show of hands, every person who is present and entitled to vote,
whether as a Special Warrantholder or as proxy for one or more absent Special
Warrantholders or both, shall have one vote. On a poll each Special
Warrantholder present in person or represented by a proxy duly appointed by
instrument in writing shall be entitled to one vote in respect of each Special
Warrant then held by him. A proxy need not be a Special Warrantholder.

8.9  Regulations

     The Trustee, or the Company with the approval of the Trustee, may from
time to time make or vary such regulations as they shall think fit:

     (a)  for the issue of voting certificates by any bank, trust company or
          other depository satisfactory to the Trustee stating that the Special
          Warrants specified therein have been deposited with the depository by
          a named person and will remain on deposit until a specified date,
          which voting certificates shall entitle the persons named therein to
          be present and vote at the meeting of the Special Warrantholders and
          at any adjournment thereof held before that date or to appoint a
          proxy or proxies to represent them and vote for them at any such
          meeting and at any adjournment thereof held before that date in the
          same manner and with the same effect as though the persons so named
          in the voting certificates were the actual holders of the Special
          Warrants specified therein;

     (b)  for the deposit of voting certificates and/or instruments appointing
          proxies at such place and time as the Trustee, the Company or the

          proxies at some approved place or places other than the place at
          which the meeting is to be held and enabling particulars of the
          voting certificates and/or instruments appointing proxies to be sent
          by mail, cable, telex or other means of prepaid, transmitted,

          the place where the same is to be held and for the voting of proxies
          so deposited as though the instruments themselves were produced at
          the meeting;

     (d)  for the form of instrument appointing a proxy (which shall be in
          writing), the manner in which the same shall be executed and the
          verification of any authority under which a person executes a proxy
          on behalf of a Special Warrantholder; and

     (e)  generally for the calling of meetings of Special Warrantholders and
          the conduct of business thereat.

Any regulations so made shall be binding and effective and the votes given in
accordance therewith shall be valid and shall be counted.  Save as the
regulations may provide, the only persons who shall be recognized at any
meeting as the holders of any Special Warrants, or as entitled to vote or,
subject to section 8.10, be present at the meeting in respect thereof, shall be
persons who are the registered holders of Special Warrants or their duly
appointed proxyholders.

8.10 Company and Trustee may be Represented

          which shall be agreed to by the Company, and to authorize the Trustee
          to concur in and execute any indenture supplement, except that in

9.1  Provision for Supplemental Indentures for Certain Purposes

     (b)  adding to the provisions hereof such additional covenants and
          enforcement provisions as, in the opinion of counsel, are necessary
          or advisable, provided that the same are not in the opinion of the
          Trustee prejudicial to the interests of the Special Warrantholders as
          a group;

     (c)  giving effect to any Extraordinary Resolution passed as provided in
          Article Eight;

     (d)  adding to, deleting or altering the provisions hereof in respect of

          Certificate which additions, deletions or alterations, in the opinion
          of the Trustee, do not affect the substance thereof;

     (e)  making any additions to, deletions from or alterations of the
          provisions of this Indenture which, in the opinion of the Trustee, do
          not materially and adversely affect the interests of the Special
          Warrantholders and are necessary or advisable in order to
          incorporate, reflect or comply with any Applicable Legislation;

     (f)  making provisions not inconsistent with this Indenture as may be
          necessary or desirable with respect to matters or questions arising
          hereunder or for the purpose of obtaining a listing or quotation of
          the Shares issuable under the Special Warrants on a stock exchange,
          bourse or over-the-counter market, provided that the provisions are
          not, in the opinion of the Trustee, prejudicial to the interests of

          Company from any of the obligations, conditions or restrictions

          be or become operative or effective if in the opinion of the Trustee





                                     - 43 -
   48
          the modification or relief impairs any of the rights of the Special
          Warrantholders provided hereunder, or of the Trustee, and provided
          that the Trustee may in its uncontrolled discretion decline to enter
          into any supplemental indenture which in its opinion may not afford
          adequate protection to the Trustee when the same shall become
          operative;

     (h)  evidencing any succession, or successive successions, of other bodies
          corporate to the Company and the assumption by any successor of the
          obligations of the Company herein and in the Special Warrant
          Certificates as provided hereafter in this Article Nine; and

          Indenture, including the correction or rectification of any
          ambiguities, defective provisions, errors or omissions herein,

provisions hereof and all obligations for the due and punctual performance and
observance of each and every covenant and obligation contained in this
Indenture to be performed by the Company and, if requested by the Trustee, the
successor corporation shall by supplemental indenture satisfactory in form to
the Trustee and executed and delivered to the Trustee, expressly assume those
obligations.

10.2 Rights and Duties of Trustee

     (1) In the exercise of the rights, duties and obligations prescribed or
conferred by the terms of this Indenture, the Trustee shall act honestly and in
good faith with a view to the best interests of the Special Warrantholders and
shall exercise that degree of care, diligence and skill that a reasonably
prudent trustee would exercise in comparable circumstances.

     (2) No provision of this Indenture will be construed to relieve the
Trustee from liability for its own negligent act, negligent failure to act,
wilful misconduct or bad faith.

     (3) The obligation of the Trustee to commence or continue any act, action
or proceeding for the purpose of enforcing any rights of the Trustee or the
Special Warrantholders or obligations of the Company hereunder shall be
conditional upon either the Special Warrantholders or the Company furnishing,
when required by notice in writing by the Trustee, sufficient funds to commence
or continue the act, action or proceeding and an indemnity reasonably
satisfactory to the Trustee to protect and hold harmless the Trustee against
the costs, charges and expenses and liabilities to be incurred thereby and any
loss and damage it may suffer by reason thereof. None of the provisions
contained in this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers unless indemnified as
aforesaid.

     (4) The Trustee may, before commencing any such act, action or proceeding,
or at any time during the continuance thereof require the Special
Warrantholders at whose instance it is acting to deposit with the Trustee the
Special Warrant Certificates held by them, for which Special Warrant
Certificates the Trustee shall issue receipts.

     (5) Every provision of this Indenture that by its terms relieves the
Trustee of liability or entitles it to rely upon any evidence submitted to it
is subject to the provisions of Applicable Legislation, and of this section
10.2 and section 10.3.

10.3 Evidence, Experts and Advisers

     (1) In addition to the reports, certificates, opinions and other evidence
required by this Indenture, the Company shall furnish to the Trustee such
additional evidence of compliance with any provision hereof, and in such form,
as may be prescribed by Applicable Legislation or as the Trustee may reasonably
require by written notice to the Company.

     (2) In the exercise of its rights and duties hereunder the Trustee may, if
it is acting in good faith, rely as to the truth of the statements and the
accuracy of the opinions expressed therein, upon statutory declarations,
opinions, reports, certificates or





                                     - 45 -
   50
other evidence furnished to the Trustee pursuant to any provision hereof or of
Applicable Legislation or pursuant to a request of the Trustee, provided that
the evidence complies with Applicable Legislation and that the Trustee examines
such evidence and determines that the evidence complies with the applicable
requirements of this Indenture.

     (3) Whenever Applicable Legislation requires that evidence referred to in
subsection 10.3(1) be in the form of a statutory declaration, the Trustee may
accept the statutory declaration in lieu of a certificate of the Company
required by any provision hereof. Any such statutory declaration may be made by
one or more of the officers of the Company.

     (4) Proof of the execution of an instrument in writing, including a
Special Warrantholders' Request, by any Special Warrantholder may be made by
the certificate of a notary public, or other person with similar powers, that
the person signing the instrument acknowledged to him the execution thereof, or
by an affidavit of a witness to the execution or in any other manner that the
Trustee may consider adequate.

     (5) The Trustee may employ or retain such counsel, accountants, engineers,
appraisers, or other experts or advisers as it may reasonably require for the
purpose of discharging its duties hereunder and may pay reasonable remuneration
for all services so performed by any of them, without taxation of costs of any
counsel, and shall not be responsible for any misconduct on the part of any of
them.

     (6) The Trustee may as a condition precedent to any action to be taken by
it under this Indenture require such opinions, statutory declarations, reports,
certificates or other evidence as it, acting reasonably, considers necessary or
advisable in the circumstances.

10.4 Securities, Documents and Monies Held by Trustee

     Any securities, documents of title or other instruments that may at any
time be held by the Trustee subject to the trusts hereof may be placed in the
deposit vaults of the Trustee or of any of the Canadian Imperial Bank of
Commerce, Bank of Montreal, Bank of Nova Scotia, The Toronto-Dominion Bank, the
Royal Bank of Canada and the Hongkong Bank of Canada or deposited for
safekeeping with any of those Canadian chartered banks. Unless herein otherwise
expressly provided, any money so held pending the application or withdrawal
thereof under any provision of this Indenture shall be deposited in the name of
the Trustee in any of the foregoing Canadian chartered banks at the rate of
interest, if any, then current on similar deposits or, with the consent of the
Company, be:

     (a)  deposited in the deposit department of the Trustee or of any other
          loan or trust company authorized to accept





                                     - 46 -
   51
          deposits under the laws of Canada or a province thereof whose short
          term debt obligations or deposits have a rating of at least R1 as
          rated by Dominion Bond Rating Service; or

     (b)  invested in securities issued or guaranteed by the Government of
          Canada or a province thereof or in obligations, maturing not more
          than one year from the date of investment, of or guaranteed by any of
          the foregoing Canadian chartered bank or loan or trust company.

Subject to the provisions of section 6.4, unless the Company is in default
hereunder, all interest or other income received by the Trustee in respect of
deposits and investments will belong to the Company.

10.5 Action by Trustee to Protect Interests

     The Trustee shall have power to institute and to maintain such actions and
proceedings as it may consider necessary or expedient to preserve, protect or
enforce its interests and the interests of the Special Warrantholders.

10.6 Trustee not Required to Give Security

     The Trustee shall not be required to give any bond or security in respect
of the execution of the trusts and powers of this Indenture or otherwise in
respect of the premises contained herein.

10.7 Protection of Trustee

     By way of supplement to the provisions of any law from time to time
applicable to trustees, it is expressly declared and agreed as follows:

     (1) The Trustee shall not be liable for or by reason of any
representations, statements of fact or recitals in this Indenture or in the
Special Warrant Certificates (except the representation contained in section
10.9 or by virtue of the certification by the Trustee of the Special Warrant
Certificates) or required to verify the same, but all those statements or
recitals are and shall be deemed to be made by the Company.

     (2) Nothing herein contained shall impose any obligation on the Trustee to
see to or to require evidence of the registration (or filing or renewal
thereof) of this Indenture or any instrument ancillary or supplemental hereto.

     (3) The Trustee shall not be bound to give notice to any person or persons
of the execution hereof.





                                     - 47 -
   52
     (4) The Trustee shall not incur any liability or responsibility whatever
or be in any way responsible for the consequence of any breach on the part of
the Company of any of the covenants or warranties herein contained or of any
acts of any director, officer, employee or agent of the Company.

     (5) The Trustee shall not be bound to give any notice or to do or take any
act, action or proceeding by virtue of the powers conferred on it hereby unless
and until it shall have been required so to do under the terms hereof nor shall
the Trustee be required to take notice of any default of the Company hereunder
unless and until notified in writing of the default (which notice must specify
the nature of the default) and, in the absence of that notice, the Trustee may
for all purposes hereunder conclusively assume that no default by the Company
hereunder has occurred. The giving of any notice shall in no way limit the
discretion of the Trustee hereunder as to whether any action is required to be
taken in respect of any default hereunder.

     (6) The Trustee shall not be accountable with respect to the validity or
value (or the kind or amount) of any Shares or Warrants or other securities or
property which may at any time be issued or delivered upon the exercise of the
rights attaching to any Special Warrant.

     (7) The Trustee is not responsible for any failure of the Company to make
any cash payment or to issue, transfer or deliver Shares or Warrants or
certificates for the same upon the surrender or deemed surrender of any Special
Warrant Certificates for the purpose of the exercise of the Special Warrants
represented by such Special Warrant Certificates or to comply with any of the
covenants contained in Article Five.

10.8 Replacement of Trustee

     (1) The Trustee may resign its trust and be discharged from all further
duties and liabilities hereunder, except as provided in this Article Ten, by
giving to the Company and the Special Warrantholders not less than 90 days'
notice in writing or, if a new Trustee has been appointed such shorter notice
as the Company may accept as sufficient. The Special Warrantholders by
Extraordinary Resolution shall have power at any time, with the consent of the
Company, not to be unreasonably withheld, to remove the Trustee and to appoint
a new Trustee. In the event of the Trustee resigning or being removed as
aforesaid or being dissolved, becoming bankrupt, going into liquidation or
otherwise becoming incapable of acting hereunder, the Company shall forthwith
appoint a new Trustee unless a new Trustee has already been appointed by the
Special Warrantholders; failing that appointment by the Company, the retiring
Trustee or any Special Warrantholder may apply to the Supreme Court of British
Columbia, on such notice as the Court may direct, for the appointment of a new
Trustee; but any new Trustee so appointed by the Company or by the Court shall
be subject to removal as aforesaid by the Special Warrantholders and





                                     - 48 -
   53
the Company.  Any new Trustee appointed under any provision of this section
10.8 shall be a corporation authorized to carry on the business of a trust
company in the Provinces of British Columbia and Ontario and, if required by
the Applicable Legislation of any other Province, in that other Province.  On
any appointment, the new Trustee shall be vested with the same powers, rights,
duties and responsibilities as if it had been originally named herein as
Trustee without any further assurance, conveyance, act or deed; but there shall
be immediately executed, at the expense of the Company, all such conveyances or
other instruments as may, in the opinion of counsel, be necessary or advisable
for the purpose of assuring such powers, rights, duties and responsibilities of
the new Trustee.

     (2) Upon the appointment of a new Trustee, the Company shall promptly give
notice thereof to the Special Warrantholders.

     (3) Any corporation into or with which the Trustee may be merged or
consolidated or amalgamated, or any corporation succeeding to the trust
business of the Trustee, shall be the successor to the Trustee hereunder
without any further act on its part or any of the parties hereto provided that
the corporation would be eligible for appointment as a new Trustee under
subsection 10.8(1).

     (4) Any Special Warrant Certificates certified but not delivered by a
predecessor Trustee may be certified by the new or successor Trustee in the
name of the predecessor or new or successor Trustee.

10.9 Conflict of Interest

     (1) The Trustee represents to the Company that at the time of the
execution and delivery hereof no material conflict of interest exists between
the Trustee's role as a fiduciary hereunder and its role in any other capacity
and agrees that in the event of a material conflict of interest arising
hereafter it will, within 90 days after ascertaining that it has a material
conflict of interest, either eliminate the same or assign its trust hereunder
to a successor Trustee approved by the Company and meeting the requirements set
forth in subsection 10.8(1). Notwithstanding the foregoing provisions of this
subsection 10.9(1), if any such material conflict of interest exists or
hereafter shall exist, the validity and enforceability of this Indenture and
the Special Warrant Certificate shall not be affected in any manner whatsoever
by reason thereof.

     (2) Subject to subsection 10.9(1), the Trustee, in its personal or any
other capacity, may buy, lend upon and deal in securities of the Company may
act as registrar and transfer agent for the Shares and trustee for the Warrants
under the Warrant Indenture and generally may contract and enter into financial
transactions with the Company or any subsidiary of the Company, all without
being liable to account for any profit made thereby.

provided for, agrees to perform the same upon the terms and conditions herein
set forth and agrees to hold all rights, interests and benefits contained
herein for and on behalf of those persons who become holders of Special
Warrants from time to time issued pursuant to this Indenture.

10.11 Trustee not to be Appointed Receiver

     The Trustee and any person related to the Trustee shall not be appointed a
receiver, a receiver and manager or liquidator of all or any part of the assets
or undertaking of the Company.

10.12 Indemnity

     Without limiting any protection or indemnity of the Trustee under any
other provision hereof, or otherwise at law, the Company hereby agrees to
indemnify and hold harmless the Trustee from and against any and all
liabilities, losses, damages, penalties, claims, actions, suits, costs,
expenses and disbursements, including reasonable legal or advisor fees and
disbursements, of whatever kind and nature which may at any time be imposed on,
incurred by or asserted against the Trustee in connection with the performance
of its duties and obligations hereunder, other than such liabilities, losses,
damages, penalties, claims, actions, suits, costs, expenses and disbursements
arising by reason of the negligence, wilful misconduct or bad faith of the
Trustee or persons for whom the Trustee is responsible. This provision shall
survive the resignation or removal of the Trustee, or the termination of the
Indenture.

and any notice given in accordance with the foregoing shall be deemed to have

following the day of the mailing of the notice or, if transmitted by facsimile,
on the day following the transmission.

     (2) The Company or the Trustee, as the case may be, may from time to time

threatened, involving postal employees, any notice to be given to the Trustee
or to the Company hereunder could reasonably be considered unlikely to reach or
to be delayed in reaching its destination, the notice shall be valid and
effective





                                     - 51 -

giving the notice.

11.2 Notice to Special Warrantholders

     (1) Unless herein otherwise expressly provided, any notice to be given
hereunder to Special Warrantholders shall be written and shall be deemed to be
validly given if the notice is sent by prepaid mail, addressed to the holder or
delivered by hand or transmitted by facsimile (or so mailed to certain holders
and so delivered to other holders and so transmitted by facsimile to other
holders) at their respective addresses and facsimile numbers appearing on the
register maintained by the Trustee; and if in the case of joint holders of any
Special Warrants more than one address or facsimile number appears on the
register in respect of that joint holding, the notice shall be addressed or
delivered, as the case may be, only to the first address or facsimile number,
as the case may be, so appearing. The Trustee shall give, in the same manner as
for Special Warrantholders set out above, a copy of each such notice to

on the day of delivery by hand or facsimile or, if mailed, on the next business
day following the day of mailing of the notice. Accidental error or omission in
giving notice or accidental failure to mail notice to any Warrantholder shall
not invalidate any action or proceeding founded thereon.

     (2) If, by reason of strike, lock-out or other work stoppage, actual or
threatened, involving postal employees, any notice to be given to the Special
Warrantholders hereunder could reasonably be considered unlikely to reach or be
delayed in reaching its destination, the notice shall be valid and effective if
published or distributed once in the Report on Business section of the national
edition of The Globe and Mail newspaper, or, in the event of a disruption in
the circulation of that newspaper, once in a daily newspaper in the English
language approved by the Trustee of general circulation in the Cities of
Toronto and Vancouver; provided that in the case of a notice convening a
meeting of the holders of Special Warrants, the Trustee may require such
additional publications of that notice, in the same or in other cities or both,
as it may deem necessary for the reasonable protection of the holders of
Special Warrants or to comply with any applicable requirement of law or any
stock exchange. Any notice so given shall be deemed to have been given on the
day on which it has been published in all of the cities in which publication
was





                                     - 52 -
   57
required (or first published in a city if more than one publication in that
city is required).  In determining under any provision hereof, the date when
notice of any meeting or other event must be given, the date of giving notice
shall be included and the date of the meeting or other event shall be excluded.

11.3 Satisfaction and Discharge of Indenture

     Upon the date by which certificates representing Shares and Warrants shall
have been delivered to Special Warrantholders to the full extent of the rights
attached to all Special Warrants theretofore certified hereunder and the monies
to be paid hereunder, if any, have been paid, this Indenture shall cease to be
of further effect and the Trustee, on demand of and at the cost and expense of
the Company and upon delivery to the Trustee of a certificate of the Company
stating that all conditions precedent to the satisfaction and discharge of this
Indenture have been complied with and upon payment to the Trustee of the fees
and other remuneration payable to the Trustee, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture.

11.4 Sole Benefit of Parties and Special Warrantholders

     Nothing in this Indenture or in the Special Warrant Certificates,
expressed or implied, shall give or be construed to give to any person other
than the parties hereto and the Special Warrantholders any legal or equitable
right, remedy or claim under this Indenture, or under any covenant or provision
therein contained, all such covenants and provisions being for the sole benefit
of the parties hereto and the Special Warrantholders.

     Any matter provided herein to be determined by the directors will be
determined acting reasonably in their sole discretion, and a determination so
made will be conclusive.

     This Indenture may be executed in several counterparts, each of which when
so executed shall be deemed to be an original and the counterparts together
shall constitute one and the same

          acquired upon the exercise of the Special Warrants by the last of the
          securities regulatory authorities to do so in each of the Provinces
          of British Columbia and Ontario (the "Qualification Date"); and

     (b)  July 24, 1996 or such later date as the underwriters of the offering
          of the Special Warrants may determine in a written notice delivered
          to the Company and the Trustee, provided that such underwriters have
          obtained the written consent thereto of each initial purchaser of the
          Special Warrants who have not resold their Special Warrants (the
          "Qualification Deadline").

     If the Qualification Date occurs on or before the Qualification Deadline,
the Trustee will give notice to each holder of Special Warrants specifying that
the Qualification Date has occurred on or before the Qualification Deadline and
specifying the duration and expiry of the Exercise Period.

     The Special Warrants represented by this Special Warrant Certificate may
be exercised by the holder during the Exercise Period by:

     (a)  duly completing and executing the attached exercise form; and

     (b)  surrendering this Special Warrant Certificate to the Trustee at the
          principal transfer office of the Trustee in either of the Cities of
          Toronto or Vancouver.

     The Special Warrants represented by this Special Warrant Certificate shall
be effectively surrendered (unless deemed to be surrendered) only upon personal
delivery hereof or, if sent by mail or other means of transmission, upon actual
receipt thereof by the Trustee at either of the offices referred to above.

     Upon surrender of the Special Warrants, the person or persons in whose
name or names the Shares and Warrants issuable upon exercise of the Special
Warrants are issued shall be deemed for all purposes (except as provided in the
Special Warrant Indenture) to be the holder or holders of record of such Shares
and Warrants. The Company has covenanted that it will deliver (subject





                                      A-2
   61
to the provisions of the Special Warrant Indenture) to the Trustee as agent for
such person or persons, certificates representing such Shares and Warrants and
the Trustee has covenanted that it will cause such certificates to be mailed by
registered mail to such person or persons at the address or addresses specified
to the Exercise Form forthwith.

     The holders of these Special Warrants may exercise these Special Warrants
with respect to a lesser number of Special Warrants than the number represented
by this Special Warrant Certificate. In such event, the Holder shall be
entitled to receive a new Special Warrant Certificate for the balance of the
Special Warrants which remain unexercised. No fractional Shares or Warrants
will be issued.

     The Special Warrant Indenture provides for: (i) adjustments to certain
rights of the holder, including the number of Shares issuable upon exercise or
deemed exercise, upon the happening of certain stated events, including the
subdivision or consolidation of the outstanding Shares, certain distributions
of Shares or securities convertible or exchangeable into Shares or of other
securities or assets of the Company, certain offerings of rights, warrants or
options, and certain capital reorganizations; and (ii) payment of an amount to
compensate for dividends paid on Shares prior to the exercise of the Special
Warrants.

     If, immediately prior to the expiry of the Exercise Period, the Special
Warrants represented by this Special Warrant Certificate have not been
exercised, the Special Warrants represented hereby shall be deemed to have been
exercised and surrendered by the holder immediately after that time without any
further action on the part of the holder.

     If the Special Warrants represented by this Special Warrant Certificate
are exercised or are deemed to be exercised by the holder notwithstanding that
the Qualification Date has not occurred, any such exercise or deemed exercise
shall be subject to the holder providing such assurances and executing such
documents as the Company or the Trustee, acting reasonably, may require to
ensure compliance with applicable securities legislation.

     One hundred percent (100%) of the original consideration received by the
Company for the Special Warrants is held in escrow by the Trustee and may be
deposited with certain Canadian chartered banks or loan or trust companies or
invested in short-term debt obligations issued or guaranteed by the Government
of Canada or a province thereof. If the Qualification Date has not occurred on
or before the Qualification Deadline, the holder of the Special Warrants
represented by this Special Warrant Certificate may elect to retract such
Special Warrants by duly completing an election form and delivering such form
and to the Trustee at its principal office in either of the cities of Vancouver
or Toronto on or before 4:30 p.m. (local time) on the fifth business day after
the Qualification Deadline and the Trustee shall deliver to the holder the
purchase price for the Special Warrants so retracted, together with all
interest earned thereon. The purchase price held in





                                      A-3
   62
escrow of each Special Warrant that has not been retracted will be released,
together with all interest earned thereon, to the Company on the exercise or
deemed exercise of each such Special Warrant.  If the Qualification Date has
occurred on or before the Qualification Deadline, 100% of the gross proceeds
held in escrow from the issue of the Special Warrants will be released,
together with all interest earned thereon, to the Company on the fifth business
day after the Qualification Date.

     The holder of this Special Warrant Certificate may, upon surrender hereof
to the Trustee at its principal transfer office in either of the Cities of
Toronto or Vancouver, subject to the provisions of the Special Warrant
Indenture and in compliance with the reasonable requirements of the Trustee,
exchange one or more Special Warrant Certificates for one or more Special
Warrant Certificates of different denomination evidencing Special Warrants
entitling the holder to receive in the aggregate the same number of Shares and
Warrants as may be acquired pursuant to the Special Warrant Certificate being
exchanged.

     The holding of the Special Warrants evidenced by this Special Warrant
Certificate shall not constitute the holder hereof a shareholder of the Company
or entitle the holder to any right or interest in respect thereof except as
herein and in the Special Warrant Indenture expressly provided.

     The parties hereto have declared that they have required that these
presents and all other documents related hereto be in the English language. Les
parties aux presentes declarent qu'elles ont exige que la presente convention,
de meme que tous les documents s'y rapportant, soient rediges en anglais.

     The Special Warrants represented by this Special Warrant Certificate, the
Shares and Warrants to be issued upon exercise thereof, and the Shares to be
issued upon exercise of the Warrants, have not been registered under the United
States Securities Act of 1933, as amended (the "U.S. Securities Act") or any
applicable State securities laws of the United States. Subject to certain
exceptions Special Warrants, and the Warrants to be issued upon exercise of the
Special Warrants, may not be exercised by U.S. Persons or persons within the
United States unless such securities and Shares issuable upon exercise thereof
are registered under the U.S. Securities Act and the securities laws of all
applicable States of the United States or an exemption from such registration
requirements is available. Terms used in this paragraph have the meanings given
to them in Regulation S under the U.S. Securities Act.

     This Special Warrant Certificate shall not be valid for any purpose
whatsoever unless and until it has been certified by or on behalf of the
Trustee under the Special Warrant Indenture.





                                      A-4

     Time shall be of the essence hereof.

     IN WITNESS WHEREOF Granges Inc. has caused this Special Warrant
Certificate to be duly executed as of the 25th day of April, 1996.
