--------------------------------------------------------------------------------

 

21

  7.1.1.   the presence, on or within the Peñasquito Concessions or such Other
Concessions as the case may be of any reagent, chemical, contaminant, pollutant,

in each case whether disclosed in environmental audits or other material
provided by the Vendor or KEC to the Purchaser or identified through
investigations carried out by or on behalf of the Purchaser and disclosed in
writing to the Vendor (collectively, the “Assumed Liabilities”), and the
Purchaser shall, subject to the limitations set forth in Section 7.2, indemnify
and save the Vendor and KEC harmless from all claims, demands, suits and actions

or relate to events, acts or omissions that occurred prior to the Penasquito

obligation to indemnify increases) by the aggregate amount of any liability of
the Vendor and KEC, limited by Section 7.5.4, for breach of the representation
and warranty in Section 3.1.12.

--------------------------------------------------------------------------------

 

22

7.3.   Payment of Certain Taxes on Sale and Transfer       Each of the parties
has concluded that no value added tax (impuesto al valor agregado) or transfer
tax is payable to any Mexican Governmental Authority in respect of the sale and
transfer of the Royalties to the Purchaser pursuant to this Agreement.
Nonetheless the Purchaser shall be responsible for and shall pay when due any
such value added tax or transfer tax payable by the Vendor or KEC or either of
them or by the Purchaser in respect of the sale and transfer of the Royalties to
the Purchaser. The Vendor and the Purchaser shall use their commercially
reasonable efforts in good faith to minimize or eliminate any such value added
tax or transfer tax. The Purchaser shall have the right to contest the
imposition of any such tax and the Vendor and KEC shall cooperate with the
Purchaser in any opposition, contest or challenge to any attempt by any Mexican
Governmental Authority to impose any such tax. Notwithstanding the foregoing
provisions of this Section 7.3, the Purchaser shall have no obligation to pay
any taxes due with respect to or based on (a) the income or capital gains
(impuesto sobre la renta) whether resulting from cash or other consideration
received by the Vendor for the sale of the Royalties or (b) any profit sharing
obligation or other employee compensation liability or social responsibility tax
of the Vendor or KEC.   7.4.   Indemnification by Purchaser       In accordance
with the procedures in Section 7.6, the Purchaser shall indemnify the Vendor,

directors, officers, employees, agents, and representatives harmless from any
and all damages, claims, losses, liabilities, fines, penalties and expenses
(including without limitation, expenses of investigation, attorneys’ fees in
connection with any action, suit or proceeding brought against any of them, the
cost of all studies, surveys, clean-up and any other environmental expenses)
incurred or suffered by the Vendor, KEC, or their respective directors,
officers, employees, agents, and representatives or any of them arising out of:

  7.4.1.   any misrepresentation or breach of warranty of which Notice has been
given under Section 7.6 before expiration of the representation or warranty as
provided in Section 9.2;     7.4.2.   any covenant or agreement made or to be
performed by the Purchaser pursuant to this Agreement; and     7.4.3.   any

against and agree to hold the Purchaser and its directors, officers, employees,
agents, and representatives harmless from any and all damages, claims, losses,
liabilities, fines, penalties and expenses (including without limitation,
expenses of investigation, attorneys’ fees and expenses in connection with any
action, suit or

--------------------------------------------------------------------------------

 

23

proceeding brought against the Purchaser, the cost of all studies, surveys,
clean-up and any other environmental expenses) incurred or suffered by the
Purchaser or its directors, officers, employees, agents, and representatives
arising out of:

  7.5.1.   any misrepresentation or breach of warranty of which Notice has been
given under Section 7.6 before expiration of the representation or warranty as
provided in Section 9.1;     7.5.2.   any covenant or agreement made or to be
performed by the Vendor or KEC pursuant to this Agreement; and     7.5.3.   any
liabilities or obligations assumed in Section 7.3;

provided that notwithstanding the foregoing or anything else in this Agreement:

  7.5.4.   the liability of the Vendor and KEC collectively for breach of the
representation and warranty in Section 3.1.12 shall be limited in the aggregate
to the lesser of $10,000,000 or the difference between $10,000,000 and the
aggregate of any losses referred to in Section 7.2 which materialize.

If the Vendor and KEC pay the Purchaser on account of the obligation to
indemnify against breach of the representation and warranty in Section 3.1.12
and subsequently losses referred to in Section 7.2 materialize which, if they
had materialized first, would have reduced the amount required to be paid by the
Vendor and KEC, the Purchaser will repay the difference to KEC.
The Vendor and KEC acknowledge that they retain responsibility for the amount of
certain losses as provided in Section 7.2.

7.6.   Claims of Indemnity       A party claiming for indemnity under this
Article 7 (the “Indemnitee”) shall give prompt Notice of any claim, action,
proceeding or circumstances that could reasonably give rise to such a claim to
the party which has agreed to indemnify it (the “Indemnitor”). Inadvertent
failure to give such prompt Notice will not preclude the Indemnitee from
pursuing the claim unless and to the extent that the Indemnitor is materially
prejudiced by such failure. The Indemnitor may, and will, if directed to do so
by the Indemnitee, at its own expense and in the name of the Indemnitee or
otherwise, dispute any claim made, or any matter on which a claim could be made,
by a third party in respect of which a Notice has been given by the Indemnitee
under this Section 7.6 and may retain legal counsel acceptable to the Indemnitee
to have conduct of any proceeding relating to such a claim. The Indemnitee may
employ separate counsel with respect to any such claims brought by a third party
and participate in the defense thereof, provided the fees and expenses of such
counsel shall be the responsibility of the Indemnitee unless:

  7.6.1.   the Indemnitor fails to assume the defence of such claim on behalf of
the Indemnitee within five days of receiving Notice of such claim; or     7.6.2.
  the employment of such counsel has been authorized by the Indemnitor;

--------------------------------------------------------------------------------

 

24

in each of which cases the Indemnitor shall not have the right to assume the
defense of such suit on behalf of the Indemnitee but shall be liable to pay the
reasonable fees and expenses of counsel for the Indemnitee. For the purpose of
confirming or disputing such a claim, the Indemnitee will provide full and
complete disclosure to the Indemnitor and complete access to and right of
inspection by the representatives of the Indemnitor of all documents and records
in the possession or control of the Indemnitee relating to such claim. If any
security is required to be provided for the purpose of defending or contesting
any such claim, including, without limitation, any appeal of any judgment, the
Indemnitor shall provide such security and all monies or property representing
such security received by the Indemnitee as a result of a successful defense or
contestation will be held in trust by the Indemnitee for the benefit of the
Indemnitor and will be remitted to the Indemnitor on demand. Neither the
Indemnitee nor the Indemnitor shall settle, compromise or pay any claim for
which indemnity is sought hereunder except with the prior written consent of the
other, such consent not to be unreasonably withheld, or in the case of the
Indemnitee unless the Indemnitor fails to dispute and defend such claim.

8.   POST-CLOSING MATTERS   8.1.   Royalty Payments       From and after the
Peñasquito Royalty Closing, the Purchaser will be entitled to the full use and
enjoyment of the Peñasquito Royalty, including without limitation all payments
thereunder. From and after the Other Royalties Closing, the Purchaser will be
entitled to the full use and enjoyment of the Other Royalties acquired by the
Purchaser, including without limitation all payments thereunder.   8.2.  
Consents and Approvals       Where the consent or approval of any Governmental
Authority is required to transfer, or assign or recognize the Royalties to and
in the name of the Purchaser and has not been obtained on or before the
Peñasquito Royalty Closing Date or the Other Royalties Closing Date, as the case
may be, the Vendor will continue to hold the Royalties pending receipt by the
Purchaser of such consent or approval, provided that the Vendor’ sole obligation
hereunder will be to hold the Royalties, to remit any payments in respect
thereof to the Purchaser, and to carry out at the request and expense of the
Purchaser such acts in compliance with applicable Law as must be carried out by
the holder thereof. The Purchaser will be responsible for and will pay, and will
indemnify and hold the Vendor and KEC and each of them harmless from, any and
all Taxes applicable to or arising from the receipt by the Vendor of payments of
the Royalties or the remittance of the Royalties to the Purchaser.   8.3.  
Further Assurances       From and after the Peñasquito Royalty Closing each of

thereof. Kennecott shall at all reasonable times on reasonable notice to Western
have access to the information and data generated from Western’s Operations and
to the Properties and to Western’s Operations, provided that Kennecott shall not
interfere with Western’s activities hereunder. Kennecott will have the right
from time to time on reasonable notice to Western to audit and make copies of
the books and records of Western that pertain to Operations.   4.11.   Western
shall indemnify and save harmless Kennecott from and against any and all claims,
debts, demands, suits, actions and causes of action whatsoever which may be
brought or made against Kennecott by any person, firm or corporation and all
loss, cost, damages, expenses and liabilities which may be suffered or incurred
by Kennecott arising out of or in

connection with or in any way referable to, whether directly or indirectly, the
entry on, presence on, or activities on the Properties or the approaches thereto
by Western or its servants or agents, or, insofar as they are acting at the
direction of Western, by the geoscientist or other technical or administrative
support staff provided by Kennecott pursuant to Section 4.5, including without
limitation bodily injuries or death at any time resulting therefrom or damage to
property.

4.12.   Western shall maintain, during the Alliance Term, the following
insurance:

  4.12.1.   the Mexican equivalent, if any, of Worker’s Compensation Insurance
for employees which is in full compliance with all applicable laws of the State
of Zacatecas or the United States of Mexico;     4.12.2.   Comprehensive General

the liability assumed under any indemnity provided herein, with a limit of
liability for bodily injury of $1,000,000 each occurrence and $1,000,000
aggregate and for property damage of $1,000,000 each occurrence and $1,000,000
aggregate,     4.12.3.   Comprehensive Automobile Insurance including all owned,
non-owned and hired vehicles with not less than the following limits:

                 
 
    4.12.3.1.     Bodily Injury   $1,000,000 each person
 
              $1,000,000 each occurrence
 
               
 
    4.12.3.2.     Properties Damage   $500,000 each occurrence

All policies in subsection 4.12.2 shall be endorsed to provide that 30 days
prior written notice will be given to Kennecott by the carrier before effecting
cancellation or material change of coverage. In addition, all liability policies
shall be endorsed to include Kennecott and all subsidiary, associated and
affiliated companies as additional insureds.
During the Alliance Term, Western shall not commence any work until a
certificate in evidence of insurance coverage has been provided to Kennecott,
nor shall Western allow any

--------------------------------------------------------------------------------

 

14

subcontractors to commence work until a similar evidence for each subcontractor
has been obtained and approved by Western. Western shall be responsible for
compliance by all subcontractors with these insurance requirements.
A certificate evidencing the required insurance shall be made out to Kennecott,
and shall be furnished to Kennecott promptly after issuance and must reflect
both the endorsement provisions requiring 30 days prior written notice to be
given before cancellation or material change, and the additional interests where
applicable. Each certificate shall specify the date when such benefits and
insurance expire.
Western agrees that such benefits and insurance, as specified above, shall be
provided and maintained until the Alliance Term expires. The original
certificate shall be mailed or delivered to Kennecott.
If at any time the required insurance policies should be cancelled, terminated,
or modified so that the insurance is not in full force and effect as required
herein, Kennecott may at its option obtain insurance coverage equal to that
required herein, with the cost thereof chargeable to Western.
Kennecott and all of its subsidiary, associated and affiliated companies shall
be released and held harmless by Western and its subcontractors for all loss of
or damage to Western’s and/or its subcontractors’ sheds, tools, equipment,
and/or materials, or to any property of its employees.

4.13.   The liability of Western assumed under this Agreement shall in no manner
be limited by the amount of the insurance which Western is required to provide
by the provisions hereof.   4.14.   Western will, at its own expense, repair any
damage to all property as required by law, whether such property is publicly or
privately owned, including the property of Kennecott, which may result from
Western’s performance of this Agreement.

5   BACK-IN RIGHTS   5.1.   Western will not mine or remove ores, minerals or
metals from any concession comprised in the Properties, except in
non-commercially saleable quantities for the purpose of sampling, testing and
assaying, without first providing to Kennecott:

  5.1.1.   a copy of a report certified by a recognized firm of competent,
professional engineers stating that drilling by Western on the concession (a
“Development Property”) has defined an inferred resource thereon; and     5.1.2.
  a detailed statement audited and verified by a recognized firm of competent
chartered accountants showing the aggregate amount of (i) the Expenditures
incurred and paid by Western on that Development Property; (ii) the aggregate
amount of any and all payments by Western made pursuant to the Underlying
Agreement, if any, that pertains to the Development Property; and (iii) the
aggregate amount that Western paid to Kennecott to acquire that Development
Property from Kennecott (the aggregate of the foregoing amounts being hereafter
called the “Back-in Price”).

(the date on which all of the above have been received by Kennecott being
hereinafter called the “Notice Date”).

5.2.   Kennecott shall have and Western hereby grants separately in respect of
each Development Property the option (the “Back-in Right”) to reacquire from
Western a 51% undivided right, title and interest in the Development Property
and in all information, property and assets, both real and personal, acquired by
the expenditure of Expenditures thereon, free and clear of all liens, charges,
encumbrances, security interests, liabilities and adverse claims whatsoever that
were not existing on the date of this Agreement. Kennecott may exercise the
Back-in Right by delivering notice of exercise to Western within the time
provided in Section 5.4 and within 30 days thereafter providing Western with
payment of an amount which, subject to Section 5.5, shall be equal to 150% of
51% of the Back-in Price for that Development Property, whereupon Kennecott
shall acquire and be vested with a 51% undivided right, title and interest in
and to the Development

--------------------------------------------------------------------------------

 

16

Property and all information, property and assets, both real and personal,
acquired by the expenditure of the Expenditures thereon, free and clear as
aforesaid. Failure to exercise a Back-in Right as provided herein shall be
deemed to be an election not to exercise such Back-in Right.

5.3.   Kennecott shall have the right to conduct its own audit of the Back-in
Price claimed by Western and to dispute the amount or any portion thereof within
50 days after the Notice Date. Such dispute shall be referred to a single
arbitrator acting under the Commercial Arbitration Act (British Columbia), whose
decision shall be final and binding. The party in whose favour the arbitrator’s
decision is made will pay the costs of the arbitration.   5.4.   If the amount
(the “Disputed Amount”) that Kennecott in good faith disputes is more than 10%
of the Back-in Price claimed by Western, then Kennecott may exercise the Back-in
Right within 60 days after the Notice Date or 30 days after any dispute is
resolved under Section 5.3, whichever is later. If the Disputed Amount is 10% or
less of the Back-in Price claimed by Western, then Kennecott may exercise the
Back-in Right within 60 days after the Notice Date (the date by which Kennecott
must give notice being hereinafter called the “Exercise Date”).   5.5.   If the
Disputed Amount is 10% or less of the Back-in Price claimed by Western,
Kennecott may defer payment of 150% of 51% of the Disputed Amount until the
dispute is resolved by arbitration. Within 10 days after the arbitrator’s
decision, Kennecott will pay to Western 150% of 51% of the Disputed Amount to
the extent that the arbitrator determines that it was properly included in the
Back-in Price. If the arbitrator finds that the whole of the Disputed Amount was
properly included, Kennecott shall also pay to Western interest on the deferred
payment at an annual rate equal to the Prime Rate plus 2% calculated from the
Exercise Date to the date of payment.   5.6.   If Kennecott exercises a
Back-in-Right in respect of a Development Property it must either:

--------------------------------------------------------------------------------

 

17

  5.6.1.   incur aggregate Expenditures in respect of that Development Property
and/or make payments to third parties pursuant to the Underlying Agreement or
other agreement pertaining thereto of US $25,000,000, or     5.6.2.   make a
Production Decision in respect of that Development Property,

within 60 months from the Exercise Date applicable to that Development Property.
Additionally, at least US$1,000,000 of the US $25,000,000 referred to above must
be incurred or paid in each of five successive years, the first of which
commences on the Exercise Date.

5.7.   Kennecott may accelerate any or all of the Expenditures contemplated by
Section 5.6. Kennecott may at any time from time to time pay to Western money in
lieu of incurring Expenditures under Section 5.6, if sufficient Expenditures
have been incurred to maintain the Development Property in good standing, in
which event Kennecott shall be deemed to have incurred additional Expenditures
in the same amount as the amount of any such payment and in satisfaction of such
of the provisions of Section 5.6 as indicated by Kennecott at the time of the
making of such payment. Any excess payments or Expenditures made or incurred in
any period will be carried forward and applied as a credit against Expenditures
to be made in the next succeeding period or periods.   5.8.   If from time to
time Kennecott is prevented by Force Majeure from incurring Expenditures or
making a Production Decision as provided in Section 5.6 then Kennecott shall
have such additional time as is reasonable in the circumstances to do so, the
amount of such additional time not to exceed the duration of the Force Majeure.
  5.9.   If Kennecott does not satisfy the requirements in Section 5.6 in
respect of a Development Property, it will at its own expense and without
reimbursement of any amounts that it paid to exercise its Back-in Right in
respect of that Development Property provide to Western a duly executed
retransfer of its right, title and interest in that Development Property, and
Kennecott will then have no further rights or obligations hereunder, including
without limitation under Section 5.6, with respect to that Development Property.

--------------------------------------------------------------------------------

 

18

6.   ROYALTIES   6.1.   For each Development Property in respect of which
Kennecott does not exercise the Back-in Right, Kennecott shall be entitled to
and Western will pay each year a royalty equal to a percentage of Net Smelter
Returns from the Development Property. The percentage will be 2% in respect of
each Development Property that was a Kennecott Concession or the Penasquito
Project (with the Penasquito Project deemed to be a single Development Property)
and 1% in respect of each Development Property that was a Western Concession.
The maximum aggregate amount payable by Western on account of each such royalty
will be US $15,000,000 if the royalty pertains to a Kennecott Concession or the
Penasquito Project or US $7,500,000 if the royalty pertains to a Western
Concession.   6.2.   “Net Smelter Returns” shall be calculated and paid as
provided in Schedule 1.14.   6.3.   The royalties granted hereunder shall
constitute an interest in land that will run with the land.   7.   TRANSFERS OF
THE PROPERTIES   7.1.   Subject to Section 7.2, if at any time during the
Alliance Term Kennecott intends to sell or otherwise dispose of one or more
concessions (the “Subject Property”) located in the Alliance Area that are not
comprised in the Kennecott Concessions, Western shall have a right to purchase
the same as follows:

  7.1.1.   Kennecott shall provide notice in writing to Western that identifies
the Subject Property and states the aggregate amount, in current U.S. dollars,
that has been expended on the Subject Property up to the date of the notice to
explore or develop it in accordance with good mining practice and to acquire and
maintain title to it, plus 5% thereof in lieu of home office or administration
expenses (the total thereof being hereinafter referred to as “Historical Cost”)
The delivery of such notice shall constitute an offer by Kennecott to Western to
dispose of the Subject Property to Western for a purchase price equal to

--------------------------------------------------------------------------------

 

19

the Historical Cost, provided that Western may elect to pay such price in U.S.
dollars or Canadian dollars or in Shares, with the exchange rate between U.S.
and Canadian dollars being the rate in effect on the date of Kennecott’s notice
to Western and the price per Share equal to the weighted average price at which
such Shares traded on the Toronto Stock Exchange on the ten days (exclusive of
holidays) preceding the delivery of such notice by Kennecott). Western shall
have 30 days from the date of such notice to elect to acquire the Subject
Property by delivering to Kennecott, within such 30 days, payment of the
Historical Cost by way of a certified cheque for U.S. dollars or Canadian
dollars in the appropriate amount or delivery to Kennecott of the appropriate
number of fully paid and non-assessable Shares represented by a duly executed
share certificate in the name of Minera Kennecott;

  7.1.2.   if Western fails to so elect and pay for the Subject Property within
the time provided for in Section 7.1.1, Kennecott shall have 90 days following
the expiration of such period to sell or otherwise dispose of the Subject
Property or any interest in it for consideration of such value (which may be
greater or less than the Historical Cost) and of such kind as Kennecott may
choose to accept from the purchasing party;     7.1.3.   if Kennecott fails to
consummate such transaction within the period set forth in Section 7.1.2, the
right of Western under this Section 7.1 shall be deemed to be revived and any
subsequent disposition by Kennecott during the Alliance Term of any concessions
located in the Alliance Area that are not Kennecott Concessions shall again be
conducted in accordance with the provisions of Section 7.1; and     7.1.4.   If
Western exercises its right to acquire concessions from Kennecott pursuant to
this Section 7.1, such concessions shall be deemed to be Kennecott Concessions
for all purposes of this Agreement.

7.2.   Kennecott shall have the right without restriction under Section 7.1 to:

--------------------------------------------------------------------------------

 

20

which Western has given notice under Section 3.1 and the 30 day period referred
to in Section 3.1 has not expired) unless:

  7.3.1.   the person to whom the disposition is being made first agrees with
Kennecott in writing to be bound by this Agreement including without limitation
Article 6 and, unless Kennecott has waived its Back-in Right in respect of the
property pursuant to Section 7.6, Article 5, such agreement to be in form and
content satisfactory to Kennecott; and     7.3.2.   if the Penasquito Project
or. the Kennecott Concessions or any of them are included in the disposition,
Kennecott has given its prior written consent; and     7.3.3.   if the
Penasquito Project or the Kennecott Concessions or any of them are included in
the disposition and at any time after the date of this Agreement there has been
a change in, or an acquisition by any person or group of persons of, control of
WTC, Western has first provided Kennecott with a right of first refusal as
provided in Section 7.5, which Kennecott has not exercised.

7.4.   Western shall have the right without restriction under Section 7.3 to
transfer the Properties to a corporation at least 99.9% of the shares of which
are beneficially owned and held by WTC or Minera Western, provided that such
corporation agrees in writing with Kennecott to hold the Properties subject to
this Agreement, the form and content of such agreement in writing to be as
Kennecott may reasonably require.   7.5.   If Western intends to sell, assign,
transfer, convey or otherwise dispose of the Penasquito Project, the Kennecott
Concessions, or any of them or any interest therein, (the “Subject Interest”) as
permitted by Section 7.3 but in circumstances where Section 7.3.3 applies,
Kennecott shall have a right of first refusal as follows:

  7.5.1.   Western shall promptly notify Kennecott of its intentions. The notice
shall be accompanied by an executed agreement (the “Third Party Agreement”)
entered into by Western in good faith with an arm’s length third party that
provides for all of the terms of the intended disposition and is subject to

--------------------------------------------------------------------------------

 

21

Interest”) as permitted by Section 7.3 except in circumstances where
Section 7.3.3 applies, Kennecott shall have a right of first refusal as follows:

  7.5.1.   Western shall promptly notify Kennecott of its intentions, The notice
shall be accompanied by an executed agreement (the “Third Party Agreement”)
entered into by Western in good faith with an arm’s length third party that
provides for all of the terms of the intended disposition and is subject to
Kennecott’s right in this Section 7.5. If the purchase price and consideration
does not consist solely of cash the notice shall also state Western’s good faith
calculation of the fair market value of such consideration stated in U.S. or
Canadian dollars. If Kennecott in good faith disputes such valuation within
10 days of receipt of the notice from Western it may refer the matter to a
single arbitrator under the Commercial Arbitration Act (British Columbia) whose
decision shall be final and binding on the parties. The delivery of such notice
and Third Party Agreement shall constitute an offer by Western to Kennecott to
dispose of the Subject Interest to Kennecott on the same terms and conditions as
provided in the Third Party Agreement, provided that Kennecott may elect to pay
the fair market value of such consideration in U.S. or Canadian dollars.
Kennecott shall have 30 days from the date of such notice or the date on which
the arbitrator’s decision is made, whichever is later to notify Western whether
it elects to acquire the Subject Interest. If it does so elect, the disposition
shall be consummated promptly after notice of such election is delivered to
Western;     7.5.2.   if Kennecott fails to so elect within the time provided
for in Section 7.5.1, Western shall have 90 days following the expiration of
such period to consummate the transaction provided by the Third Party Agreement
but subject to Kennecott’s rights under this Agreement; and     7.5.3.   if
Western fails to consummate such transaction within the period set forth in
Section 7.5.2, the right of first refusal of Kennecott under this Section 7.5
shall be deemed to be revived. Any subsequent proposal to dispose of any

 

--------------------------------------------------------------------------------

 

22
rights or interests of Western shall again be conducted in accordance with the
provisions of Section 7.5.

7.6.   If Western intends, at any time before the same has become a Development
Project, to sell, transfer or assign all or an interest in the Penasquito
Project or any of the Kennecott Concessions to an arm’s length third party for
consideration which Western in good faith believes represents the fair market
value thereof Western may require Kennecott to waive its Back-in Right in
respect thereof at the closing of the sale thereof to the arm’s length third
party, in consideration for payment to Kennecott at such closing of 10% of such
consideration. The request for such waiver will be made to Kennecott at least
15 days but not more than 30 days before the intended closing date and shall be
accompanied by a copy of the purchase agreement and an affidavit of a senior
officer of Western stating that the consideration specified therein is all of
the consideration to be received by Western for the sale of such property and
that such officer in good faith believes it to be the fair market value thereof.
As provided in Section 7.3.1, the third-party purchaser must acknowledge that it
is acquiring the property subject to Kennecott’s right to be paid a royalty in
respect of that property pursuant to Article 6 hereof.   7.7.   Western will not
mortgage, charge, pledge or otherwise encumber any of the Properties without the
prior written consent of Kennecott, except for the sole purpose of raising funds
to be expended on the development of the Properties.   8.   CORPORATION AND
SHAREHOLDERS AGREEMENT   8.1.   If from time to time Kennecott exercises the
Back-in Right on any Development Property and completes the expenditures
required by Section 5.6, then as soon as reasonably possible thereafter,
Kennecott and Western shall meet to finalize an appropriate corporate structure
for the post-exploration mining activities on that Development Property and
cause a Corporation to be incorporated. Such corporation shall be governed
pursuant to the terms of the Shareholders Agreement. Kennecott and Western agree
that the final corporate structure and organization shall be in accordance with
the Shareholders Agreement and shall be one which will minimize tax liability
and optimize profit repatriation for both Kennecott and Western. Incorporation
of the Corporation, its

 

--------------------------------------------------------------------------------

 

23
organization and the subscription of the Shares shall be completed no later than
30 days following the exercise by Kennecott of a Back-in Right. A Shareholders
Agreement shall be entered into and a new Corporation shall be incorporated for
each Development Property. For the purposes of Section 4.1 of the Shareholders
Agreement, the agreed value of a Development Property will be the Back-in Price
applicable to it plus the Expenditures incurred by Kennecott under Section 5.6
in respect of it.

8.2.   Unless otherwise agreed to in writing, Kennecott and Western, to the
extent of their respective interests in accordance with Section 5.2, shall pay
all costs and expenses incurred or accrued by either of them which are directly
or reasonably related to the incorporation, organisation or setting up of the
Corporation (the “Preincorporation Expenses”). Preincorporation Expenses shall
include, but not be limited to, any and all stamp taxes, import duties, other
taxes’ or duties,, filing or other fees, assessments or other payments made to a
Governmental Authority, notary public and legal fees and disbursements and any
costs or expenses directly or reasonably incurred or accrued by either Kennecott
or Western (the “Paying Party”) to third parties, shall not include costs and
expenses incurred or accrued internally by the Paying Party or its Affiliates.  
8.3.   Preincorporation Expenses incurred to third parties shall be reimbursed
to the Paying Party in the amount and currency actually incurred by the Paying
Party. Within 60 days following the date of incorporation of the Corporation,
the Paying Party shall submit to the non-Paying Party invoices for the
Preincorporation Expenses specifying the non-Paying Party’s share of all such
Preincorporation Expenses not previously billed or invoiced to the non-Paying
Party.   8.4.   The non-Paying Party shall pay its pro rata share of
Preincorporation Expenses as set forth in any invoice submitted to it by the
Paying Party pursuant to Section 8.3 within 30 days after such invoice is sent
to the non-Paying Party.   8.5.   Upon the incorporation and organization of the
Corporation and the issuance of Shares in accordance with Section 4.1 of the
Shareholders Agreement, of which 51% will be issued to Minera Kennecott and 49%
will be issued to Minera Western, Kennecott shall complete

 

--------------------------------------------------------------------------------

 

24
the date on page 1 of the Shareholders Agreement which shall be the date on
which the Corporation was incorporated and any other information required by
such form. Kennecott shall also complete Schedule A thereto with a description
of the Development Property and each of the parties shall then execute and
deliver to the other a copy of the Shareholders Agreement and all documents and
instruments contemplated by the Shareholders Agreement to be executed and
delivered concurrently with or following the entering into of the Shareholders
Agreement.

8.6.   Kennecott and Western shall not be liable to one another for losses
sustained or liabilities incurred by either Kennecott or Western or their
respective Affiliates relating to or arising out of the incorporation,
organization or setting up of the Corporation (“Preincorporation Activities”),
except as may result from Kennecott’s or Western’s (or their respective
Affiliates’) negligence or wilful misconduct. Neither Kennecott nor Western nor
their Affiliates shall in any event have any liability to the other for
incidental, consequential, indirect, exemplary or punitive damages for losses or
liabilities to or arising out of Preincorporation Activities.   8.7.   None of
the provisions in this Agreement will merge in the Shareholders Agreement and
this Agreement will survive the execution and delivery thereof. For greater
certainty but without limiting the scope of Article 9 hereof, the parties
acknowledge that Kennecott’s rights under Article 9 hereof shall continue to
apply in respect of funds that Minera Western requires to carry out the purposes
and intent of each Shareholders Agreement.   9.   WESTERN’S FINANCING
REQUIREMENTS   9.1.   From and after the date hereof, Western shall provide
written notice to Kennecott of any and all transactions proposed to be entered
into or corporate actions proposed to be taken by Western or any subsidiary
thereof for the purpose, directly or indirectly, of raising funds (each such
transaction being hereinafter referred to as a “Financing”). Each such notice
provided by Western shall set out the terms and conditions on which such
Financing is proposed to be entered into (which may include the approval of the
Toronto Stock Exchange or other securities regulatory authority) and shall be
deemed to constitute an

 

--------------------------------------------------------------------------------

 

25
offer (a “Financing Offer”) to Kennecott to participate in such Financing upon
such terms and conditions by providing a fraction of the funds to be raised
under the financing, where the numerator of such fraction is the number of
Shares at that time held by Kennecott and the denominator of such fraction is
the total number of Shares at that time issued and outstanding. The terms and
conditions of the Financing Offer shall be set out in sufficient detail that the
acceptance thereof by Kennecott would constitute a binding agreement between the
parties to complete the Financing as to the portion to be provided by Kennecott
on such terms and conditions and, without limiting the generality of the
foregoing, such terms and conditions shall include the closing date (which shall
be a date not more than 90 days from the date of the Financing Offer) for such
Financing and:

  9.1.1.   in the case of a Financing involving the issue and sale of shares of
WTC or a subsidiary thereof, the number and class of shares proposed to be
issued and sold, the purchase price therefor and any special rights or
restrictions attached to such shares;     9.1.2.   in the case of a Financing
involving a loan to be made to or a debt to be incurred by Western or a
subsidiary thereof, the principal amount and term of such loan or debt, the
applicable interest rate and details regarding the calculation and payment
thereof and provisions relating to any security to be granted in respect of the
loan or debt;     9.1.3.   if the Financing is conditional on Western receiving
from the proposed sources of funds (collectively, the “investors”) commitments
to provide an amount which in the aggregate is not less than a specified amount,
details of such condition; and     9.1.4.   if the Financing is conditional on
Western receiving from each investor a commitment to provide an amount which is
not less than a specified amount, details of such condition.

9.2.   Kennecott shall provide written notice to Western of its acceptance or
rejection of each Financing Offer within 72 hours after the receipt by it
thereof, provided however that

 

--------------------------------------------------------------------------------

 

26
Western shall not present Kennecott with a Financing Offer unless it has
previously given to Kennecott at least 20 days notice of all material terms of
the Financing other than pricing matters, including dividend or interest rates
as applicable.

9.3.   If Kennecott accepts a Financing Offer as to participation in the
Financing as to all or a portion of the funds intended to be raised thereby by
Western or a subsidiary thereof, Western or such subsidiary and Kennecott shall
complete the Financing (or the portion thereof in respect of which Kennecott has
determined to participate) on the terms and conditions set out in the Financing
Offer, with any and all such amendments thereto as they may agree upon in
writing. Kennecott may, at its option, from time to time complete any Financing
accepted by it through any Affiliate.   9.4.   If Kennecott declines to
participate in a Financing Offer Western may complete the Financing with other
investors on and subject to the terms and conditions set out in the Financing
Offer. Any amendment to such terms and conditions such that they are materially
less favourable to Western or any amendment or waiver of a condition made
pursuant to Subsection 9.1.3 or Subsection 9.1.4 shall be deemed to constitute a
new Financing and shall require Western to make a Financing Offer to Kennecott
to participate in such new proposed Financing on such amended terms and
conditions in accordance with the provisions of Section 9.1, in which case the
provisions of this Article 9 shall apply mutatis mutandis to such new proposed
Financing.   9.5.   WTC may issue Shares as consideration for the acquisition of
mineral properties without obligation to Kennecott under Section 9.1. Each time
that WTC issues Shares as consideration for the acquisition of mineral
properties it will, at the same time, to the extent permitted by applicable
securities laws, offer to allot and issue to Kennecott the number of Shares
which is in the same proportion to the number of such Shares so issued as
consideration for the acquisition of mineral properties as the number of Shares
then held by Kennecott is to the total number of Shares then outstanding, at a
price per share equal to the weighted average price at which such shares traded
on the Toronto Stock Exchange on the ten days (exclusive of holidays) preceding
the date of such offer on

 

--------------------------------------------------------------------------------

 

27
which Shares were traded. The offer by Western shall be open for acceptance by
Kennecott for 30 days.

Schedule E
Termination of Property Rights Agreement

 

--------------------------------------------------------------------------------

 

TERMINATION OF PROPERTY RIGHTS AGREEMENT
THIS AGREEMENT is made as of the 5th day of May, 1999, by and between KENNECOTT
EXPLORATION COMPANY, a Delaware corporation, MINERA KENNECOTT S.A. DE C.V., a
Mexico corporation (collectively, “Kennecott”), WESTERN COPPER HOLDINGS LTD., a
British Columbia corporation, and MINERA WESTERN COPPER S.A. DE C.V., a Mexico
Corporation (collectively, “Western Copper”).
WHEREAS, Kennecott and Western Copper entered into that certain Property Rights
Agreement (“Property Rights Agreement”) dated 13 March, 1998; and,
WHEREAS, The parties now wish to terminate the Property Rights Agreement;
NOW THEREFORE, in consideration of the mutual covenants and promises contained
herein, the parties agree as follows:

1.   Western Copper acknowledges that it currently owes Kennecott ONE MILLION
THREE HUNDRED FORTY-FOUR THOUSAND FIVE HUNDRED AND FIFTY-SIX UNITED STATES
DOLLARS (US$1,344,556.00) for expenses incurred by Kennecott on Western Copper’s
behalf, plus interest. Western Copper hereby confirms that the expenditures are
valid and this amount is undisputed. On or before the close of business on 5
May, 1999 (the “Effective Date”), Western Copper shall pay Kennecott such amount
in full.   2.   After the Effective Date, and performance of Western Copper’s
obligations pursuant to Paragraphs 1, 3(a) and 3(b) herein, Kennecott shall
assign, at Western Copper’s sole expense, all of Kennecott’s right, title and
interest in the Properties, as more particularly described in Exhibit A hereto,
to Western Copper or its designated assignee. Western Copper shall assume and
perform, at its sole risk and expense, all of obligations pertaining to the
Properties and shall indemnify and hold Kennecott harmless for any liabilities,
costs or expenses arising from Western Copper’s activities on the Properties.
WESTERN COPPER HEREBY ACKNOWLEDGES THAT TITLE TO SEVERAL OF THE CONCESSIONS
COMPRISING THE PROPERTIES ARE IN JEOPARDY, THROUGH NO FAULT OF KENNECOTT, DUE TO
DELINQUENT TAX AND PROPERTY PAYMENTS. ASSIGNMENT OF THE PROPERTIES TO WESTERN
COPPER SHALL BE MADE ON AN “AS IS” BASIS, AND KENNECOTT MAKES NO REPRESENTATIONS
OR WARRANTIES AS TO TITLE. If transfer of the Properties is not made as of the
Effective date, Kennecott shall continue to hold title to the Properties for the
benefit of Western Copper or its designated assignee, provided that Western
Copper acknowledges that it shall be solely responsible for the prompt payment
of taxes and property payments required to keep the Properties in good standing.
It is understood and agreed that Kennecott shall be under no obligation to make
any payments on Western Copper’s behalf. Western Copper shall indemnify and hold
Kennecott harmless for any claim of any type resulting directly or indirectly
from Western Copper’s failure to make tax or property payments in a timely
manner.   3.   As of the Effective Date, Kennecott shall surrender its Back-In
Rights on the Properties, as set forth in Section 5 of the Property Rights
Agreement. As

1

--------------------------------------------------------------------------------

 

    consideration for Kennecott surrendering such rights, on the Effective Date
Western Copper shall:

  (a)   Issue Kennecott 250,000 common shares of Western Copper common stock.
Such stock shall be subject only to such hold period as is required under the
rules of the Toronto Stock Exchange, and shall be validly issued, fully paid and
nonassessable, and free and clear of all liens. Such number of shares shall be
adjusted for any intervening subdivision of Western Copper stock or other
capital reorganization.     (b)   Amend Section 2 (b) of that certain
Subscription Agreement dated 12 March, 1998 and each of the, share purchase
warrants referred to therein, so that such warrants may be exercised any time
prior to March 12, 2001 at a price of two dollars (C$2.00) per share, subject to
such restrictions and accelerated expiry time as required by the Toronto Stock
Exchange.     (c)   In addition to performing the obligations set forth above,
Western Copper shall pay Kennecott, on or before 1 August, 1999, the sum of
fifty thousand U.S. dollars (US$50,000), plus the full amount of tax penalties
incurred for failure to make tax payments on 30 April, 1999.

4.   After the Effective Date, and performance of Western Copper’s obligations
pursuant to Paragraphs 1, 3(a) and 3 (b) herein, the Properties shall be
transferred to Western Copper subject to Kennecott’s right to receive a one
percent (1%) net smelter return royalty on Western Copper Concessions, and two
percent (2%) net smelter return royalty on kennecott Concession or the
Penasquito Property, as set forth in Section 6 of the Property Rights Agreement,
with the exception that the royalties shall no longer be capped. The net smelter
return royalty shall be payable as provided in Schedule 1.14 of the Property
Rights Agreement. A copy of Schedule 1.14 is attached hereto as Exhibit B. A
schedule of properties subject to such obligation to pay royalties is attached
hereto as Exhibit A. Any subsequent transfers of the Properties by Western
Copper shall be subject to Kennecott’s right to receive its net smelter royalty,
and any subsequent transferee shall acknowledge in writing its obligation to pay
such royalty and file, at its sole expense, such documentation as may be
necessary to acknowledge Kennecott’s right with the appropriate governmental
authorities in Mexico.       Kennecott’s royalty interest on the Villa de Ramos
claim group, as described in Exhibit C hereto, can be purchased under the
following terms.

  (a)   One million U.S. dollars (US$1,000,000) per percentage point at any time
on or before the second anniversary of this Termination Agreement; or,     (b)  
Two million U.S. dollars (US$2,000,000) per percentage point at any time after
the second anniversary, but before the third anniversary of this Termination
Agreement.     (c)   If any portion of the royalty is not purchased prior to the
third anniversary of this Termination Agreement, Kennecott’s right to receive a
net smelter return royalty, pursuant to Paragraph 4 above shall remain in full
force and effect.

2

--------------------------------------------------------------------------------

 

    The parties acknowledge that different net smelter royalty rates apply to
different concessions within the Villa de Ramos claim group. It is acknowledged
and agreed that the payment of one million U.S. dollars (US$1,000,000) under
subparagraph (a) above or two million U.S. dollars (US$2,000,000) under
subparagraph (b) above, as the case may be, acquires one percentage point from
all the royalty interest payable on the entire Villa de Ramos claim group.
Subsequently, the concessions previously subject to a one percent (1%) royalty
would have no royalty due, and the concessions subject to a two percent (2%)
royalty would be subject to a one percent (1%) royalty. The maximum percentage
amount payable to Kennecott in any buyout, where both a one percent (1%) and two
(2%) percent royalty is due, shall be two percent (2%). The rights granted
hereunder may be exercised in part under subparagraph (a) and the balance under
subparagraph (b), but exercise must be as to full percentage points only.   6.  
After the Effective Date, and performance of Western Copper’s obligations
pursuant to Paragraphs 1, 3(a) and 3 (b) herein, Kennecott shall grant Western
Copper the exclusive right to find a buyer for Kennecott’s equity interest in
Western Copper. The term of such right will be sixty (60) days from the
Effective Date. If Western Copper fails to find a buyer, ready, willing and able
to purchase Kennecott’s equity interest at a price of three dollars sixty-five
cents (C$3.65) per share or greater, then Kennecott shall be free to seek a
buyer on its own initiative without further obligation to Western Copper. The
appropriateness of any sales offer shall be determined in Kennecott’s sole
discretion. Western Copper shall not be entitled to any fees for finding a
buyer. Western Copper shall not make any representations or warranties on
Kennecott’s behalf. During and before such sixty (60) day period, Kennecott
shall be free to tender its shares to a take-over bid.   7.   Western Copper
shall, within sixty (60) days of the date hereof, return all confidential data
provided to it under Section 4.4 of the Property Rights Agreement to Kennecott.
This paragraph shall not apply to data directly related to the concessions to be
transferred to Western Copper.   8.   Western Copper shall, within sixty
(60) days of the date hereof, remove any of its property now stored in the
Kennecott’s Guadalajara office or the core shed located near the Penasquito
property. Any property not removed within the sixty (60) day period shall become
the property of Kennecott. If Western Copper wishes to store drill core in
Kennecott’s Penasquito core shed after the expiry of the sixty-day period, it
shall execute a lease, in a form acceptable to Kennecott, and make lease
payments to Kennecott of seven hundred fifty U.S. dollars (US$750) per month.  
9.   As of the Effective Date, and after the performance of Western Copper’s
obligations pursuant to Paragraphs 1, 3(a) and 3(b) herein, the Property Rights
Agreement shall terminate and the parties shall have no further reciprocal
obligations, except for Sections 2.7.2, 4.11, 4.13, 4.14, and 10.2.1 which shall
survive such termination, and the provisions of this Termination Agreement.  
10.   Time shall be of the essence hereof. Western Copper shall be obligated to
pay the amounts set forth in Paragraph 1 on or before 5 May, 1999, and the
references herein to the Effective Date are not intended to provide Western
Copper with a grace period.
