              USE

              The
      Parties have negotiated the basic terms of an agreement whereby USE will
      grant TCM an exclusive option to acquire certain interests in the Property

persons.

            

    

    

    The
representations and warranties set forth above shall survive the execution and
delivery of any documents of Transfer provided under this
Agreement.

    

    3.3           Knowledge of
Parties.  For a representation or warranty made to a Party’s
“knowledge,” the term
“knowledge” shall mean the actual knowledge on the part of the officers and
directors of the applicable Party, or of facts that would reasonably lead to the
indicated conclusions, and it is a requirement that such persons must have made
the enquiries that are reasonably necessary to enable the applicable Party to
make the representation, statement or disclosure.

    

    3.4           Disclosures.  Each
of the Parties represents and warrants that it is unaware of any material facts
or circumstances that have not been disclosed in this Agreement that should be
disclosed to the other Parties in order to prevent the representations and
warranties in this Article III from being materially misleading.  USE
has disclosed to TCM all information it believes to be relevant concerning the
Assets and Property, and has provided to or made available for inspection by TCM
all such information, but does not make any representation or warranty, express
or implied, as to the value of the Assets or Property.  Each Party
represents to the other that in negotiating and entering into this Agreement it
has relied solely on its own appraisals and estimates as to the value of the
Assets and Property and upon its own geologic and engineering interpretations
related thereto.

    

    3.5           Loss of Title.  Any
failure or loss of title to any of the Assets, and all costs of defending,
curing and clarifying title, shall be charged to the Business Account, and TCM
shall be entitled to include such costs as Expenditures.

    3.6           Royalties, Production Taxes and Other
Payments Based on Production.  All required payments of
production taxes and other payments to private parties and governmental entities
shall be determined and made by the Manager.  In the event that the
Manager fails to make any such required payment, the other Party shall have the
right to make such payment and shall thereby become subrogated to the rights of
such third party; provided, however, the making of any such payment on behalf of
the Manager shall not constitute acceptance by the paying Party of any liability
to such third party for the underlying obligation.

    

    3.7           Confidentiality of
Agreement.  Without limiting any other provision hereof
concerning confidentiality of information, each Party agrees to keep the terms
and conditions of this Agreement strictly confidential, unless disclosure of any
such terms and conditions is required by law or unless the other Party consents
in writing to such disclosure in advance, such consent not to be unreasonably
withheld.

              Additional
      Project Expenditures.  By July
      31, 2018, TCM shall incur additional Expenditures on or related to the
      Property in an amount equal to the difference between the total
      Expenditures incurred under Section 6.1(a)(i) and the $50,000,000 amount
      required to acquire a 50% interest in the
  Property.

              Any
      excess Expenditures completed in advance of a due date specified in
      Section 6.1(a) shall be carried over and shall qualify, and be accounted
      for, as Expenditures completed by the subsequent due
      date.  Further, the Expenditure deadlines described above
      establish only the maximum period of time within which TCM must make such
      Expenditures; nothing in this Agreement will preclude TCM from making, in
      its sole discretion, any or all such Expenditures at any time or from time
      to time ahead of such deadlines.  In this respect, TCM may, in
      its sole discretion, make any or all such Expenditures in advance by
      paying any or all of the amounts required under Section 6.1(a) to an
      interest bearing escrow account maintained by TCM for the benefit of the
      Property.  Such payments shall be referred to as “Advance
      Payments.”  If this Agreement is terminated before TCM
      acquires any interest in the Property under Section 6.2, USE shall be
      entitled to all such Advance Payments and interest, if any, remaining in
      escrow.  If this Agreement is terminated after TCM has acquired
      an interest in the Property under Section 6.2, all such Advance Payments
      and interest, if any, remaining in escrow shall be considered Business
      capital.  Such Advance Payments, including interest, may be
      withdrawn and applied as necessary only towards future Expenditures by TCM
      on or related to the Property; provided, however, such
      amounts may not be used to meet other Expenditure requirements of TCM
      hereunder or in any way reduce the aggregate Expenditures that TCM must
      incur by a deadline in Section 6.1(a) in order to acquire any interest in
      the Property.

              TCM
      may elect to pay to an interest bearing escrow account on or before a due
      date specified in Section 6.1(a) the dollar amount equal to any shortfall
      in Expenditures required to be completed by TCM by such due date in lieu
      of completing such Expenditures, and such amounts shall thereupon be
      deemed to have satisfied such requirement for the completion of
      Expenditures by a deadline in Section 6.1(a), as
      applicable.  Such payments shall be referred to as “Shortfall
      Payments.”  If this Agreement is terminated, USE shall be
      entitled to all such Shortfall Payments and interest, if any, remaining in
      escrow.  So long as this Agreement remains in effect, such
      Shortfall Payments, including interest, may be withdrawn and applied as
      necessary only towards future Expenditures by TCM on or related to the
      Property; provided,
      however, such amounts may not be used to meet other Expenditure
      requirements of TCM hereunder or in any way reduce the

    6.2           Option Stages.  The
Option shall be exercised in two stages as follows (as further described in
Section 6.5):

    

    
      	
               
      

            	
              (a)

            	
              Upon
      TCM incurring at least $15,000,000 in Expenditures as described in Section
      6.1(a)(i), TCM may, in its sole discretion, elect to acquire a 15%
      interest in the Property upon written notice to USE at any time within
      thirty-six months after the last day of the month in which TCM has
      incurred the $15,000,000 in Expenditures as described in Section
      6.1(a)(i).  (By way of example, if TCM incurs the full
      $15,000,000 on August 12, 2010, it would then have thirty-six months from
      August 31, 2010, or until August 31, 2013, to exercise its
      election.)  Failure by TCM to make such election within the
      required thirty-six months shall be deemed to be an election by TCM to
      acquire such 15% interest in the
Property.

              If
      TCM incurs the additional Expenditures as described in Section 6.1(a)(ii)
      by July 31, 2018 (which amount, combined with the Expenditures incurred
      under Section 6.1(a)(i), shall equal $50,000,000), TCM may, in its sole
      discretion, elect to acquire an additional 35% (or aggregate 50%) interest
      in the Property, with such election being made by written notice to USE
      within 30 days after the date of the TCM accounting statement that shows
      that TCM has incurred all such Expenditures, and a failure to make such
      election shall be deemed to be an election by TCM to acquire such
      additional 35% (aggregate 50%) interest in the
  Property.

      by TCM to make all Expenditures required under Section 6.1(a)(i) (or
      Advance Payments or Shortfall Payments in lieu thereof) by the applicable
      due dates for such Expenditures (subject to Section 21.6) shall be deemed
      to be a termination of this Agreement by TCM under Section 6.3(b) if,
      within 30 days after receipt of written notice from USE regarding such
      failure, TCM does not cure such
failure.

    6.5           Exercise
of Option and Acquisition of Additional Interest in Property.

    

    
      	
               
      

            	
              (a)

            	
              Within
      six months of electing to acquire a 50% interest in the Property as
      provided in Section 6.2(b), TCM shall, in its sole discretion, choose one
      of two options:

            

    

    

    
      	
               
      

            	
              (i)

            	
              Form
      a Joint Venture on the terms set out in PART III;
  or

            

    

    

    
      	
               
      

            	
              (ii)

            	
              Form
      a Joint Venture on the terms set out in PART III but continue to fund 100%
      of all Expenditures on or related to the Property up to an additional
      $350,000,000, with the opportunity to acquire up to an additional 25%
      interest in the Property (for an aggregate 75% interest) upon incurring
      such additional $350,000,000 (which amount, combined with the initial
      $50,000,000 in Expenditures under Section 6.1(a), totals
      $400,000,000).  Upon incurring $70,000,000 in additional
      Expenditures pursuant to this Section 6.5(a)(ii) (which amount, combined
      with the initial $50,000,000 in Expenditures under Section 6.1(a), totals
      $120,000,000), TCM’s interest in the Property shall increase by 2.5% to
      52.5%.

            

    

    

    During
such time that TCM has incurred expenditures in excess of $120,000,000 in total,
but less than $400,000,000 in total, TCM’s percentage interest in the Joint
Venture shall be calculated as follows:

    

    TCM
Interest = 50 + [(Actual Expenditures - $50
Million) x 12.5]

    $350 Million

    Where:

    “TCM
Interest” means TCM’s percentage interest in the Joint Venture during the period
in which it has incurred Expenditures in excess of $120,000,000, but less than
$400,000,000.

    

    “Actual
Expenditures” means all Expenditures incurred by TCM pursuant to this
Agreement.

    

    Upon
spending the last dollar required to reach the $350,000,000 amount hereunder,
TCM’s interest in the Property shall be increased to 75% total.

      USE for any Expenditures incurred by USE between the time that TCM elects
      to acquire a 50% interest in the Property as provided under Section 6.2(b)
      and the time that TCM elects to proceed under Section 6.5(a)(ii), and any
      such reimbursements shall count towards TCM’s Expenditure obligations
      under Section 6.5(a)(ii).  At any time prior to incurring the
      entire $350,000,000 required to earn an additional 25% interest in the
      Property under Section 6.5(a)(ii), TCM may in its sole discretion
      determine that upon the beginning of the next Program and Budget adopted
      pursuant to ARTICLE IX it shall cease funding 100% of all Expenditures on
      or related to the Property and the Parties shall thereafter share such
      Expenditures in proportion to their respective Participating Interests;
      provided,
      however, TCM shall provide written notice to USE of such decision
      at least 90 days prior to the expiration of the current Program and
      Budget.

      and all such Production Royalty payments, plus administrative costs and
      third party costs necessarily incurred by TCM in relation thereto, for a
      given month shall be offset against the total amount payable by TCM to USE
      (based on the Final Price as defined in Section 11.1) pursuant to ARTICLE
      XI for that same month; provided, however, to
      the extent that Production Royalty payments and related administrative
      costs and third party costs for a given month exceed the total amount
      payable by TCM to USE pursuant to ARTICLE XI for that same month, TCM
      shall bear that excess amount entirely without compensation or

    7.2           Management
Committee.  During the Option Period, the Parties shall
establish a “Management
Committee” consisting of four members to direct and control operations
and the activities of the Manager during the Option Period.  TCM and
USE each shall be entitled to appoint two regular members to the Management
Committee.  Acting through their respective appointed members, TCM and
USE shall have an aggregate of two votes each; provided, however, in the
event of a tie vote, the Management Committee members representing TCM shall
have the deciding vote.  Both TCM and USE may appoint alternate
members to act in the absence of regular members.  Any alternates so
acting shall be deemed members.  The alternates may attend meetings of
the Management Committee even if the regular members attend; provided, however, they shall

adequate insurance for operations and for any liabilities related to operations
of the Facility.  Until TCM elects to acquire an interest in the
Property pursuant to Section 6.2, USE shall pay all operating costs for the

      as set out in the Title Opinion,

            

    

    

    even if
this necessitates the formal abandonment of some or all of the existing
unpatented mining claims.

    

    7.6           Permit Obligations of TCM During
Option Period.  TCM shall, with the cooperation of USE as
required, use its best efforts to obtain all appropriate permits prior to the
commencement of work or any required reclamation resulting from TCM’s work on
the Property.  The permits shall be in the name of
USE.  During the Option Period, decisions and actions related to
permit compliance shall be the obligation of the Management Committee, which
shall direct the actions of the Manager with respect to permit
compliance.

    

    7.7           Access to Property During Option
Period.  TCM shall at all times during the term of the Option
Period have the exclusive right to enter and engage in Operations on the
Property in accordance with this Agreement, and USE shall take all steps
reasonably necessary to permit TCM to exercise such rights.  To
facilitate the proper operation of the Facility, TCM shall keep USE informed of
TCM’s activities on the Property and as necessary coordinate such activities
with USE and the independent contractor engaged under Section 7.3.

    

    7.8           Maintenance of Property During Option
Period.  TCM shall maintain the Property in good standing and
free of all liens, other than Permitted Encumbrances, and such costs shall be
included in the Expenditures, subject to Section 18.1.

    

    7.9           Management of Existing Underground
Mine Conditions During Exploration.  USE has informed TCM that
the underground mine workings located on or beneath the Property contain liquid,
semi-solid and/or
solid material or waste associated with previous mining activities, including,
but not limited to, metal bearing sludges and mine water present behind
bulkheads and other underground mine containment structures (“underground mine
materials”).  The Parties agree that the management by TCM of
underground mine materials to prevent the uncontrolled release of such materials
into the environment may be required prior to commencement of Exploration
activities during the Option Period.  Such management may include, but
not be limited to, removal of metal-bearing sludges or other waste materials
identified by TCM and the breaching of underground bulkheads or other
containment structures and the collection, management and treatment of waste or
mine water present in the underground workings in accordance with applicable
Laws.  To facilitate the proper management of these materials, TCM
shall coordinate the management of underground mine materials existing in the
underground workings prior to or in coordination with TCM’s Exploration
activities.  As TCM determines necessary, management of the
underground waste and mine material shall be specified in a Program and
Budget.

              If
      a JV Participant’s Participating Interest becomes less than **** such Participating
      Interest shall convert to a **** Net Profits
      Interest as provided in Exhibit I and that JV
      Participant (the “Reduced
      Participant”) shall be deemed to have withdrawn from the Business.
      Such relinquished Participating Interest shall be deemed to have accrued
      automatically to the other JV Participant.  The Capital Account
      of the Reduced Participant shall be transferred to the remaining JV
      Participant.  The Reduced Participant shall thereafter have no
      further right, title or interest in or to the Assets or under this
      Agreement, with the exception of the **** Net Profits
      Interest detailed above, and any tax partnership that may have been
      created shall dissolve.  In such event, the Reduced Participant
      shall execute and deliver an appropriate conveyance of all of its right,
      title and interest in and to the Assets to the remaining JV
      Participant.

              The
      relinquishment, withdrawal and entitlements for which this Section 8.6
      provides shall be effective as of the effective date of the recalculation
      under Sections 9.4 or 10.5.  However, if the final adjustment
      provided under Section 9.5 for any recalculation under Section 9.4 results
      in a Participating Interest of 5% or more:  (i) the
      Participating Interest shall be deemed, effective retroactively as of the
      first day of the Program Period, to have automatically revested; (ii) the
      Reduced Participant shall be reinstated as a JV Participant, with all of
      the rights and obligations pertaining thereto; (iii) the right to a Net
      Profits Interest under Section 8.6(a) shall terminate; and (iv) the
      Manager, on behalf of the JV Participants, shall make any necessary
      reimbursements, reallocations of Products, contributions and other
      adjustments as provided in Section 9.5(d).  Similarly, if such
      final adjustment under Section 9.5 results in a Participating Interest for
      either JV Participant of less than **** for a Program
      Period as to which the provisional calculation under Section 9.4 had not
      resulted in a Participating Interest of less than ****, then such
      Participant, at its election within 30 days after notice of the final
      adjustment, may contribute an amount resulting in a revised final
      adjustment and resultant Participating Interest of ****.  If no
      such election is made, such JV Participant shall be deemed to have
      withdrawn under the terms of Section 8.6(a) as of the beginning of such
      Program Period, and the Manager, on behalf of the JV Participants, shall
      make any necessary reimbursements, reallocations of Products,
      contributions and other adjustments as provided in Section 9.5(d),
      including of any Net Profits Interest to which such JV Participant may be
      entitled for such Program Period.

    8.7           Continuing Liabilities Upon
Adjustments of Participating Interests.  Any reduction or
elimination of either JV Participant’s Participating Interest under Sections
8.3(b), 8.3(c) or 8.4 shall not relieve such JV Participant of its share of any
liability, including, without limitation, Continuing Obligations, Environmental
Liabilities and Environmental Compliance, whether arising out of acts or
omissions occurring or conditions existing prior to the Agreement Date or out of
Operations conducted during the term of this Agreement but prior to such
reduction or elimination, regardless of when any funds may be expended to
satisfy such liability.  For purposes of this Section 8.7, such JV
Participant’s share of such liability shall be equal to its Participating
Interest at the time the act or omission giving rise to the liability occurred,
after first taking into account any reduction, readjustment and restoration of
Participating Interests under Sections 8.6, 9.4, 9.5 and 10.5 (or, as to such
liability arising out of acts or omissions occurring or conditions existing
prior to the Agreement Date, equal to such JV Participant’s initial
Participating Interest).  Should the cumulative cost of satisfying
Continuing Obligations be in excess of cumulative amounts accrued or otherwise
charged to the Environmental Compliance Fund, each of the JV Participants shall
be liable for its proportionate share (i.e., Participating Interest
at the time of the act or omission giving rise to such liability occurred),
after first taking into account any reduction, readjustment and restoration of
Participating Interests under Sections 8.6, 9.4, 9.5 and 10.5,
of the cost of satisfying such Continuing Obligations, notwithstanding that
either JV Participant has previously withdrawn from the Business or that its
Participating Interest has been reduced or converted to an interest in Net
Profits Interest pursuant to Section 8.6(a).

    

    8.8           Documentation of Adjustments to
Participating Interests.  Adjustments to the Participating
Interests need not be evidenced during the term of this Agreement by the
execution and recording of appropriate instruments, but each JV Participant’s
Participating Interest and related Equity Account balance shall be shown in the
accounting records of the Manager, and any adjustments thereto, including any
reduction, readjustment, and restoration of Participating Interests under
Sections 8.6, 9.4, 9.5 and 10.5, shall be made monthly.  However,
either JV Participant, at any time upon the request of the other JV Participant,
shall execute and acknowledge instruments necessary to evidence such adjustments
in form sufficient for filing and recording in the jurisdiction where the
Property is located.

    

    8.9           Grant

              Subject
      to Section 8.10, each JV Participant may grant to the other JV Participant
      a lien upon and a security interest in its Participating Interest,
      including all of its right, title and interest in the Assets, whenever
      acquired or arising, and the proceeds from and accessions to the
      foregoing.

              The
      liens and security interests granted by Section 8.9(a) shall secure every
      obligation or liability of the JV Participant granting such lien or
      security interest created under this Agreement, including the obligation
      to repay a Cover Payment in accordance with Section 10.4.  Each
      JV Participant hereby agrees to take all action necessary to perfect such
      lien and security interest and hereby appoints the other JV Participant
      its attorney-in-fact to execute, file and record all financing statements
      and other documents necessary to perfect or maintain such lien and
      security interest.

    8.10           Subordination of
Interests.  Each JV Participant may, from time to time, take
all necessary actions, including execution of appropriate agreements, to pledge
and subordinate its Participating Interest, any liens it may hold which are
created under this Agreement other than those created pursuant to Sections
8.9(a) and 8.9(b), and any other right or interest it holds with respect to the
Assets (other than any statutory lien of the Manager) to any secured borrowings
for Operations approved by the Management Committee.

    

    8.11           Indemnification of
Manager.  Following the formation of the Joint Venture, USE and
TCM shall in proportion to their Participating Interests mutually hold harmless,
release, indemnify and defend the Manager (including the Manager’s Affiliates
and their respective directors, officers, employees, agents and consultants)
from and against any and all claims, demands, liabilities or losses (including
legal fees) arising from or relating to the Manager’s acts as Manager, except to
the extent that such claims, demands, liabilities or losses arise from the
Manager’s gross negligence or willful misconduct.

              From
      the date of the formation of the Joint Venture, during the term of the
      Joint Venture, the Property must be transferred to and held in the names
      of the JV Participants in proportion to their respective Participating
      Interests from time to time.

            

    

    

    
      	
               
      

            	
              (b)

            	
              Each
      JV Participant must promptly at its own cost do all things (including
      executing and if necessary delivering all documents) necessary or
      desirable to give full effect to Section 8.12(a) or the formation of the
      Joint Venture.

            

    

    

    8.13           Holding of Joint Venture
Property.  Subject to Section 8.12, all Assets, whether
acquired before or after the Agreement Date, must wherever practicable be held
by the Manager or a JV Participant who must hold it in trust for the JV
Participants as tenants in common in proportion to their respective
Participating Interests for the time being and from time to time. All Assets
held by the Manager or a JV Participant must be held, used, dealt with or
applied solely for the purposes of the Joint Venture or as otherwise permitted
under the Agreement.

    

    8.14           Management
Committee.  Upon the formation of the Joint Venture, the JV
Participants shall establish a Management Committee consisting of four regular
members to direct and control the operations of the Joint Venture, which may be
the same Management Committee provided for by Section 7.2.  Each JV
Participant shall be entitled to appoint two regular members to the Management
Committee.  Each JV Participant, acting through its appointed
member(s) in attendance at a meeting, shall have the votes on the Management
Committee in proportion to its Participating Interest; provided, however, in the
event of a tie vote, the Management Committee members representing TCM shall
have the deciding vote with regard to all matters except for the adoption of
proposed Programs and Budgets under Section 9.3(b).  In the event of a
tie vote on the adoption of a proposed Program and Budget under Section 9.3(b),
the provisions of Section 9.3(b) shall control.  Each JV Participant
may appoint alternate members to act in the absence of regular
members.  Any alternates so acting shall be deemed
members.  The alternates may attend meetings of the Management
Committee even if the regular members attend; provided however, they shall
not have the right to vote except in the place of absent regular
members.  Appointments by a JV Participant shall be made or changed by
notice

      Payout.

      contribution to the adopted Budget for that JV Participant’s estimated
      contribution at the time of the reduced JV Participant’s election under

      the Manager expended funds or incurred obligations of less than 80% of the
      adopted Budget, within 30 days of receiving the Manager’s report on
      Expenditures, the reduced JV Participant may notify the other JV
      Participant of its election to reimburse the other JV Participant for the
      difference between any amount contributed by the reduced JV Participant to
      such adopted Program and Budget and the reduced JV Participant’s
      proportionate share (at the reduced JV Participant’s former Participating
      Interest) of the actual amount expended or incurred for the Program, plus
      interest at two percentage points above the Prime Rate.  The
      reduced JV Participant shall deliver the appropriate amount (including
      interest) to the other JV Participant with such notice.  Failure
      of the reduced JV Participant to so notify and tender such amount shall
      result in dilution occurring in accordance with this ARTICLE XI and shall
      bar the reduced JV Participant from its rights under this Section 9.5(c)
      concerning the relevant adopted Program and
  Budget.

      recalculations under this Section 9.5 shall be effective as of the first
      day of the Program Period for the Program and Budget.  The
      Manager, on behalf of both JV Participants, shall make such
      reimbursements, reallocations of Products, contributions and other
      adjustments as are necessary so that, to the extent possible, each JV
      Participant shall be placed in the position it would have been in had
      their Participating Interests as recalculated under this Section been in
      effect throughout the Program Period for such Program and
      Budget.  If the JV Participants are required to make
      contributions, reimbursements or other adjustments pursuant to this
      Section, the Manager shall have the right to purchase or sell a JV
      Participant’s share of Products in the same manner as under Section
      11.1and to apply the proceeds of such purchase or sale to satisfy that JV
      Participant’s obligation to make such contributions, reimbursements or
      adjustments.

    9.6           Budget Overruns; Program
Changes.  For Programs and Budgets adopted by the Management
Committee, the Manager shall immediately notify the Management Committee of any
material departure from an adopted Program and Budget.  If the Manager
exceeds an adopted Budget by more than 20% in the aggregate, then the excess
over 20%, unless directly caused by an emergency or unexpected expenditure made
pursuant to Section 9.7, unless related to the adopted Program and Budget, or
unless directly attributable to Exploration or Development activities, must be
ratified and approved by the Management Committee at its next scheduled meeting,
and once approved shall be borne by the JV Participants (subject to Section
6.5(a)(ii) in proportion to their respective Participating
Interests.

    

    The
Manager may amend or alter the approved Program and Budget by presenting a
special item budget for review by the Management Committee.  The
Committee shall accept or reject the amendment within 10 Business Days of its
presentation. If the Committee fails to approve or reject the proposal within 10
Business Days of the presentation, the special item budget shall be deemed
approved.  The JV Participants may approve, reject, or propose
modifications for the proposed amendment in accordance with Section
9.3.

    

    9.7           Emergency or Unexpected
Expenditures.  In case of emergency, the Manager may take any
reasonable action it deems necessary to protect life or property, to protect the
Assets or to comply with Laws.  The Manager may make reasonable
expenditures on behalf of the JV Participants for unexpected events that are
beyond its reasonable control and that do not result from a breach by it of its
standard of care.  The Manager shall promptly notify the JV
Participants of the emergency or unexpected expenditure, and (subject to Section
6.5(a)(ii)) the Manager shall be reimbursed for all resulting costs by the JV
Participants in proportion to their respective Participating
Interests.

proportionate share of such cash requirements.  The Manager shall
record all funds received in the Business Account.  The Manager shall
at all times maintain a cash balance approximately equal to the rate of

amounts of the defaulted cash call shall bear interest from the date due at an
annual rate equal to five percentage points over the Prime Rate, but in no event
shall the rate of interest exceed the maximum permitted by Law.  Such
interest shall accrue to the benefit of and be payable to the non-defaulting JV
Participant, but shall not be deemed as amounts contributed by the
non-defaulting JV Participant in the event dilution occurs in accordance with

adopted Program and Budget, the non-defaulting JV Participant may, but shall not
be obligated to, advance some portion or all of the amount in default on behalf
of the defaulting JV Participant (a “Cover
Payment”).  Each and every Cover Payment shall constitute a
demand loan bearing interest from the date of the advance at the rate provided
in Section 10.3.  If more than one Cover Payment is made, the Cover
Payments shall be aggregated and the rights and remedies described herein
pertaining to an individual Cover Payment shall apply to the aggregated Cover
Payments.  The failure to repay such loan upon demand shall be a
default; provided, however, if TCM has made a Cover Payment on behalf of USE,
TCM may, at its option, treat the Cover Payment as a loan to USE, with interest
at a rate agreed upon by the Parties, to be paid out of production from the
Business.

    

    10.5           Remedies.  The JV
Participants acknowledge that if either JV Participant defaults in making a
contribution required by ARTICLE IX or a cash call, or in repaying a loan, as
required under Sections 10.2, 10.3 or 10.4, whether or not a Cover Payment is
made, it shall be difficult to measure the damages resulting from such default
(it being hereby understood and agreed that the Participants have attempted to
determine such damages in advance and determined that the calculation of such
damages cannot be ascertained with reasonable certainty).  Both JV
Participants acknowledge and recognize that the damage to the non-defaulting JV
Participant could be significant.  In the event of such default, as
reasonable liquidated damages, the non-defaulting JV Participant may, with
respect to any such default not cured within 30 days after notice to the
defaulting JV Participant of such default, elect any of the following remedies
by giving notice to the defaulting JV Participant. Such election may be made
with respect to each failure to meet a cash call relating to a Program and
Budget, regardless of the frequency of such cash calls, provided such cash calls
are made in accordance with Section 10.2.

              (a)

            	
              The
      defaulting JV Participant grants to the non-defaulting JV Participant a
      power of sale as to all or any portion of its interest in any Assets or in
      its Participating Interest that is subject to the lien and security
      interest granted in Section 8.9 (whether or not such lien and security
      interest has been perfected), upon a default under Sections 10.3 or
      10.4.  Such power shall be exercised in the manner provided by
      applicable Law or otherwise in a commercially reasonable manner and upon
      reasonable notice.  If the non-defaulting JV Participant elects
      to enforce the lien or security interest pursuant to the terms of this
      Section, the defaulting JV Participant shall be deemed to have waived any
      available right of redemption, any required valuation or appraisal of the
      secured property prior to sale, any available right to stay execution or
      to require a marshalling of assets, and any required bond in the event a
      receiver is appointed, and the defaulting JV Participant shall be liable
      for any deficiency.

              The

      Participant’s Participating Interest diluted or eliminated as

              For
      a default occurring before Payout relating to a Program and Budget
      covering in whole or in part Permitting or Exploration Operations, the
      reduced JV Participant’s Participating Interest shall be recalculated by
      dividing: (A): (1) the total of all of the reduced JV Participant’s
      contributions under Section 8.3(b) and (2) the amount, if any, the reduced
      JV Participant contributed to the adopted Program and Budget with respect
      to which the default occurred by (B) the sum of (1) and (2) above for both
      JV Participants, and then multiplying the result by one
      hundred.  For such a default occurring after Payout, the reduced
      JV Participant’s Participating Interest shall be reduced in an amount
      equal to two times the amount by which it would have been reduced if such
      default had occurred before Payout.  For such a default, whether
      occurring before or after Payout, the Participating Interest shall then be
      further reduced for a default relating exclusively to an Exploration
      Program and Budget by multiplying the recalculated Participating Interest
      by the following percentage: 150%.

            

    

    

    The
Participating Interest of the other JV Participant shall be increased by the
amount of the reduction in the Participating Interest of the reduced JV
Participant, including the further reduction under Section
10.5(b)(i).

              For
      a default relating to a Program and Budget covering in whole or in part
      Development or Mining, at the non-defaulting JV Participant’s election,
      the defaulting JV Participant shall be deemed to have withdrawn and to
      have automatically relinquished its interest in the Assets to the
      non-defaulting JV Participant; provided, however, the
      defaulting Participant shall have the right to receive only from **** of Net Profits, if
      any, and not from any other source, an amount up to **** of the defaulting
      JV Participant’s Equity Account balance at the time of such
      default.  Upon receipt of such amount the defaulting JV
      Participant shall thereafter have no further right, title or interest in
      the Assets, but shall remain liable to the extent provided in Section
      8.7.

              If
      a JV Participant has defaulted in meeting a cash call or repaying a loan,
      and if the non-defaulting JV Participant has made a Cover Payment, then,
      in addition to a reduction in the defaulting JV Participant’s
      Participating Interest effected pursuant to Section 10.5(b), the
      non-defaulting JV Participant shall have the right, if the indebtedness
      arising from a default or Cover Payment is not discharged within 10 days
      of the default and upon not less than 30 days advance notice to the
      defaulting JV Participant, to elect to purchase all the right, title, and
      interest, whenever acquired or arising, of the defaulting JV Participant
      in and to the Assets, including but not limited to its Participating
      Interest or a Net Profits Interest, together with all proceeds from and
      accessions of the foregoing (collectively the “Defaulting JV Participant’s
      Entire Interest”) at a purchase price equal to **** of the fair market
      value thereof as determined by a qualified independent appraiser appointed
      by the non-defaulting JV Participant.  If the defaulting JV
      Participant conveys notice of objection to the person so appointed within
      10 days after receiving notice thereof, then an independent and qualified
      appraiser shall be appointed by the joint action of the appraiser
      appointed by the non-defaulting JV Participant and a qualified independent
      appraiser appointed by the defaulting JV Participant; provided, however, that
      if the defaulting JV Participant fails to designate a qualified
      independent appraiser for such purpose within 10 days after giving notice
      of such objection, then the person originally designated by the
      non-defaulting JV Participant shall serve as the appraiser; provided further, that
      if the appraisers appointed by each of the JV Participants fail to appoint
      a third qualified independent appraiser within 5 days after the
      appointment of the last of them, then an appraiser shall be appointed by a
      judge of a court of competent jurisdiction in the state in which the
      Assets are situated upon the application of either JV
      Participant.  There shall be withheld from the purchase price
      payable, upon transfer of the Defaulting Participant’s Entire Interest,
      the amount of any Cover Payment under Section 10.4 and unpaid interest
      thereon to the date of such transfer, or any unpaid interest accrued in
      accordance with Section 14.3 to the date of such transfer.  Upon
      payment of such purchase price, the defaulting JV Participant shall be
      deemed to have relinquished all of the Defaulting JV Participant’s Entire
      Interest to the non-defaulting Participant, but shall remain liable to the

      year an audit shall be completed by certified public accountants selected
      by, and independent of, the Manager.  The audit shall be
      conducted in accordance with GAAP and shall cover all books and records
      maintained by the Manager pursuant to this Agreement, all Assets and
      Encumbrances, and all transactions and Operations conducted during such
      calendar year, including production and inventory records, Expenditures
      and all costs for which the Manager sought reimbursement under this
      Agreement, together with all other matters customarily included in such
      audits.  All written exceptions to and claims upon the Manager
      for discrepancies disclosed by such audit shall be made not more than 3
      months after receipt of the audit report, unless either JV Participant
      elects to conduct an independent audit pursuant to Section 10.6(b) which
      is ongoing at the end of such 3 month period, in which case such
      exceptions and claims may be made within the period provided in Section
      10.6(b).  Failure to make any such exception or claim within
      such period shall mean the audit is deemed to be correct and binding upon
      the Participants.  The cost of all audits under this subsection
      shall be charged to the Business
Account.

            

    

    

    In
conjunction with the audit, the JV Participants shall procure a review of
internal controls in compliance with Sarbanes-Oxley Act of 2002

Board.  The contractor conducting this review shall not be an
employee, officer or director of either of the JV Participants and shall be

      to the Business Account.  This audit shall review all issues
      raised by the requesting JV Participant, with all costs borne by the
      requesting JV Participant.  The requesting JV Participant shall
      give the other JV Participant 30 days’ prior written notice of such
      audit.  Any audit conducted on behalf of either JV Participant
      shall be made during the Manager’s normal business hours and shall not
      interfere with Operations.  Neither JV Participant shall have
      the right to audit records and accounts of the Business relating to
      transactions or Operations more than 24 months after the calendar year
      during which such transactions, or transactions related to such
      Operations, were charged to the Business Account.  All written
      exceptions to and claims upon the Manager for discrepancies disclosed by
      such audit shall be made not more than 3 months after completion and
      delivery of such audit, or they shall be deemed
  waived.

      and Floor.  From the Agreement Date until January 1,
      2014, the Sulfide Discount shall be no greater than **** (the “Discount
      Cap”) and no less than **** (the “Discount
      Floor”).  On January 1, 2014, and every five years thereafter,
      the Discount Cap and the Discount Floor shall be adjusted so that they
      increase or decrease to reflect changes in the Gross Domestic Product
      (“GDP”) published by the United States Department of Commerce, Bureau of
      Economic Analysis, using a GDP implicit price deflator (“GDP Deflator”)

      indices or price series as close as possible in effect to the discontinued
      index or indices, with only such adjustments thereto as may be necessary
      to reflect more closely the movements of the index which has been
      discontinued).  If they Parties cannot agree to a substitute
      index, then the dispute shall be resolved by arbitration pursuant to
      Section 19.4 of this Agreement.  During the pendency of the
      dispute, the Price shall be set by the arbitrator, and subject to
      adjustment and reimbursement or setoff upon resolution of the
      dispute.

      concentrate, with payable metal equal to **** of contained
      molybdenum in the concentrate.  The point of sale shall be FCA
      mine site as loaded on a truck for shipment as arranged by

      efforts to deliver Product pursuant to this Section 11.1, and, except for
      commercially reasonable purposes, shall not deliver from other properties
      owned or controlled by TCM in preference to this mine

      Price”).  TCM shall pay USE the Provisional Price within 20 days
      of Delivery.  ****.  Final
      payment between TCM and USE shall be made promptly upon determination of
      the Final Price.

      Rights.  USE shall have the right, at its expense, to

      reasonable notice to TCM, provided that (a) such independent third party
      auditor is reputable, (b) in any such audit, USE shall not be obligated to
      disclose to TCM any confidential information relating to any such

      disclose to the independent auditor any confidential information unless
      and until such auditor first agrees with TCM to be bound by a
      confidentiality agreement on terms and conditions reasonably satisfactory
      to TCM.  USE shall give TCM at least one month’s notice of its
      intent to audit and appoint independent auditors.  If such
      independent auditor finds a material error or material incorrectness in
      the procedures or equipment by which TCM weighs and assays Product for
      Delivery, TCM shall reimburse USE for the cost of that
    audit.

      to future invoices to reflect such adjustments.  Disputes
      concerning assays that cannot be resolved through negotiation shall be
      subject to dispute resolution pursuant to Section

    SUPPLEMENTAL
BUSINESS AGREEMENT

    

    12.1           Supplemental Business Agreement.
At any time during the Joint Venture Period, the Management Committee may
determine by unanimous vote of both JV Participants that it is appropriate to
segregate the Area of Interest into areas subject to separate Programs and
Budgets for purposes of conducting further Permitting, Exploration, Development
or Mining.  At such time, the Management Committee shall designate
which portion of the Property shall constitute an area of interest under a
separate business arrangement (“Supplemental Business”), and
the JV Participants shall enter into a new agreement (“Supplemental Business
Agreement”) for the purpose of further exploring, analyzing, developing,
and mining such portion of the Property.  The Supplemental Business
Agreement shall be in substantially the same form as that portion of this
Agreement governing the Joint Venture, with rights and interests of the JV
Participants in the Supplemental Business identical to the rights and interests
of the JV Participants in this Business at the time of the designation, unless
otherwise agreed by the JV Participants, and with the JV Participants agreeing
to new Capital and Equity Accounts and other terms necessary for the
Supplemental Business Agreement to comply with the nature and purpose of the
designation.  Following execution of the Supplemental Business
Agreement, this Agreement shall terminate insofar as it affects the Property
covered by the Supplemental Business Agreement.

    13.2           Limitations on Free
Transferability.  During the Joint Venture Period, any Transfer
by either JV Participant under Section 13.1 shall be subject to the following
limitations:

    

    
      	
               
      

            	
              (a)

            	
              neither
      JV Participant shall Transfer any interest in this Agreement or the Assets
      (including, but not limited to, any royalty, profits or other interest in
      the Products) except in conjunction with the Transfer of part or all of
      its Participating Interest;

            

    

    

    
      	
               
      

            	
              (b)

            	
              no
      JV Participant shall Transfer any interest in this Agreement or the
      Property until the selling JV Participant offers to the other JV
      Participant the opportunity to purchase the portion of the selling JV
      Participant’s Participating Interest it intends to sell (“Right of First Refusal”)
      at a price chosen by the selling JV Participant.  If the other
      JV Participant fails to purchase the Participating Interest within 20
      days, the selling JV Participant may proceed with the sale of the
      Participating Interest pursuant to this Section. The sale may not be for a
      price less than that offered to the non-selling JV
      Participant.  No transferee of all or any part of a JV
      Participant’s Participating Interest shall have the rights of a JV
      Participant unless and until the transferring JV Participant has provided
      to the other JV Participant notice of the Transfer and the transferee, as
      of the effective date of the Transfer, has committed in writing to assume
      and be bound by this Agreement to the same extent as the transferring JV
      Participant;

              neither
      JV Participant shall make a Transfer that shall violate any Law, or
      without the consent of the other JV Participant, or result in the
      cancellation of any permits, licenses or other similar
      authorization;

              no
      Transfer permitted by this Article XIII shall relieve the transferring JV
      Participant of its share of any liability, whether accruing before or
      after such Transfer, which arises out of Operations conducted prior to
      such Transfer or exists on the Agreement
Date;

              neither
      JV Participant, without the consent of the other JV Participant, shall
      make a Transfer that shall cause termination of the tax partnership
      established in Exhibit
      C.  If such termination is caused, the transferring JV
      Participant shall indemnify the other JV Participant for, from and against
      any and all loss, cost, expense, damage, liability or claim therefore
      arising from the Transfer, including without limitation any **** received by the
      Indemnified JV Participant;

      the Transfer is the grant of an Encumbrance in a Participating Interest to
      secure a loan or other indebtedness of either JV Participant in a bona
      fide transaction, other than a transaction approved unanimously by the
      Management Committee or Project Financing approved by the Management
      Committee, such Encumbrance shall be granted only in connection with such
      JV Participant’s financing payment or performance of that JV Participant’s
      obligations under this Agreement and shall be subject to the terms of this
      Agreement and the rights and interests of the other JV Participant
      hereunder (including without limitation under Section
      8.10).  Any such Encumbrance shall be further subject to the
      condition that the Chargee of such Encumbrance first enters into a written
      agreement with the other JV Participant in form satisfactory to the other
      JV Participant, acting reasonably, binding upon the Chargee, to the effect
      that:

              the
      Chargee shall not enter into possession or institute any proceedings for
      foreclosure or partition of the encumbering JV Participant’s Participating
      Interest and that such Encumbrance shall be subject to the provisions of
      this Agreement;

            

    

    

    
      	
               
      

            	
              (ii)

            	
              the
      Chargee’s remedies under the Encumbrance shall be limited to the sale of
      the whole (but only of the whole) of the encumbering JV Participant’s
      Participating Interest to the other JV Participant, or, failing such a
      sale, at a public auction to be held at least 30 days after prior notice
      to the other JV Participant, such sale to be subject to the purchaser
      entering into a written agreement with the other JV Participant whereby
      such purchaser assumes all obligations of the encumbering JV Participant
      under the terms of this Agreement.  The price of any pre-emptive
      sale to the other JV Participant shall be the remaining principal amount
      of the loan plus accrued interest and related expenses, and such
      pre-emptive sale shall occur within 60 days of the Chargee’s notice to the
      other JV Participant of its intent to sell the encumbering JV
      Participant’s Participating Interest.  Failure of a sale to the
      other JV Participant to close by the end of such period, unless failure is
      caused by the encumbering JV Participant or by the Chargee, shall permit
      the Chargee to sell the encumbering JV Participant’s Participating
      Interest at a public sale; and

      charge shall be subordinate to any then-existing debt, including Project
      Financing previously approved by the Management Committee, encumbering the
      transferring JV Participant’s Participating
  Interest;

            

    

    

    If a sale
or other commitment or disposition of Products or proceeds from the sale of
Products by either JV Participant upon distribution to it pursuant to ARTICLE XV
creates in a third party a security interest by Encumbrance in Products or
proceeds therefrom prior to such distribution, such sales, commitment or
disposition shall be subject to the terms and conditions of this Agreement,
including without limitation, Section 8.10.

    14.1           Meetings
of Management Committee.

    

    
      	
               
      

            	
              (a)

            	
              The
      Management Committee shall hold regular meetings at least quarterly at a
      location to be mutually agreed upon.  The Manager shall give 20
      days notice to TCM and USE (both referred to in this ARTICLE XIV as an
      “MC Participant”)
      of such meetings.  Additionally, either MC Participant may call
      a special meeting upon 7 days’ notice to the other MC
      Participant.  In case of an emergency, reasonable notice of a
      special meeting shall suffice.  There shall be a quorum if at
      least one regular member or alternate member representing each MC
      Participant is present; provided, however, that
      if a MC Participant fails to attend two consecutive properly called
      meetings, then a quorum shall exist at the second meeting if the other MC
      Participant is represented by at least one appointed member, and a vote of
      such MC Participant shall be considered the vote required for the purposes
      of the conduct of all business properly noticed even if such vote would
      otherwise require unanimity.

            

    

    

    
      	
               
      

            	
              (b)

            	
              If
      business cannot be conducted at a regular or special meeting due to the
      lack of a quorum, either MC Participant may call the next meeting upon 10
      days’ notice to the other MC
Participant.

            

    

    

    
      	
               
      

            	
               (c)

            	
              Each
      notice of a meeting shall include an itemized agenda prepared by the
      Manager in the case of a regular meeting or by the MC Participant calling
      the meeting in the case of a special meeting, but any matters may be
      considered if either MC Participant adds the matter to the agenda at least
      5 days before the meeting or with the consent of the other MC
      Participant.  The Manager shall prepare minutes of all meetings
      and shall distribute copies of such minutes to the other MC Participant
      within 10 days after the meeting.  Either MC Participant may
      electronically record the proceedings of a meeting with the consent of the
      other MC Participant.  The MC Participants shall sign and return
      or object to the minutes prepared by the Manager within 30 days after
      receipt, and failure to do either shall be deemed acceptance of the
      minutes as prepared by the Manager.  The minutes, when signed or
      deemed accepted by both MC Participants, shall be the official record of
      the decisions made by the Management Committee.  Decisions made
      at a Management Committee meeting shall be implemented in accordance with
      adopted Programs and Budgets.  If a MC Participant timely
      objects to minutes proposed by the Manager, the members of the Management
      Committee shall seek, for a period not to exceed 30 days from receipt by
      the Manager of notice of the objections, to agree upon minutes acceptable
      to both MC Participants.  If the Management Committee does not
      reach agreement on the minutes of the meeting within such 30 day period,
      the minutes of the meeting as prepared by the Manager together with the
      objecting MC Participant’s proposed

Business Account.  All other costs shall be paid by the Participants
individually.

     

    14.2           Action Without Meeting in
Person.  In lieu of meetings in person, the Management
Committee may conduct meetings by telephone or video conference, so long as
minutes of such meetings are prepared in accordance with Section
14.1.  The Management Committee may also take actions in writing
signed by all members.

Approval.  Except as otherwise delegated to the Manager in

methods and actions under this Agreement.  The Parties shall keep each
other informed of all material legal and regulatory matters of which they become

      revenue or net income and taxes, including production taxes, attributable

      to contest (in the courts or otherwise) the validity or amount of any
      taxes, assessments or charges if the Manager deems them to be unlawful,
      unjust, unequal or excessive, or to undertake such other steps or
      proceedings as the Manager may deem reasonably necessary to secure a
      cancellation, reduction, readjustment or equalization thereof before the
      Manager shall be required to pay them, but in no event shall the Manager
      permit or allow title to the Assets to be lost as the result of the

      thereof shall be charged to the Business

value.

      Manager shall perform or cause to be performed all assessment and other
      work and shall pay all Governmental Fees required by Law in order to
      maintain the unpatented mining claims, mill sites and tunnel sites
      included within the Property.  The Manager shall have the right
      to perform the assessment work required hereunder pursuant to a common
      plan of exploration and continued actual occupancy of such claims and
      sites shall not be required.  The Manager shall not be liable on
      account of any determination by any court or governmental agency that the
      work performed by the Manager does not constitute the required annual
      assessment work or occupancy for the purposes of preserving or maintaining
      ownership of the claims, provided that the work done is pursuant to an
      adopted Program and Budget and is performed in accordance with the
      Manager’s standard of care under Section 15.2.  The Manager
      shall timely record with the appropriate county and file with the
      appropriate United States agency any required affidavits, notices of
      intent to hold and other documents in proper form attesting to the payment
      of Governmental Fees, the performance of assessment work or intent to hold
      the claims and sites, in each case in sufficient detail to reflect
      compliance with the requirements applicable to each claim and
      site.  The Manager shall not be liable on account of any
      determination by any court or governmental agency that any such document
      submitted by the Manager does not comply with applicable requirements,
      provided that such document is prepared and recorded or filed in
      accordance with the Manager’s standard of care under Section
      15.2.

      relocation, (iii) apply for patents or mining leases or other forms of
      mineral tenure for any such unpatented claims or sites, (iv) abandon any

      records pursuant to the procedures described in Exhibit B and in

      Accounts for each JV Participant.  Each JV Participant’s Equity
      Account shall be credited with the value of such JV Participant’s
      contributions under Section 8.3(b).  Each JV Participant’s
      Equity Account shall be charged with the cash and the fair market value of
      Assets distributed to such JV Participant (net of liabilities assumed by
      such JV Participant and liabilities to which such distributed Assets are
      subject).  Contributions and distributions shall include all
      cash contributions or distributions plus the agreed value (expressed in
      dollars) of all in-kind contributions or distributions.  Solely
      for purposes of determining the Equity Account balances of the JV
      Participants, the Manager shall reasonably estimate the fair market value
      of all Products distributed to the JV Participants, and such estimated
      value shall be used regardless of the actual amount received by each JV
      Participant upon disposition of such
Products.

      of expenditures and comparisons of such expenditures to the adopted
      Budget; (ii) periodic summaries of data acquired; (iii) copies of reports

      comparisons between actual and budgeted expenditures and comparisons
      between the objectives and results of Programs; and (v) such other reports
      as any member of the Management Committee may reasonably
      request.  Subject to ARTICLE XX, at all reasonable times the
      Manager shall provide the Management Committee, or other representative of
      a JV Participant upon the request of such JV Participant’s member of the
      Management Committee, access to, and the right to inspect and, at such
      Participant’s cost and expense, copy the Existing Data and all maps, drill
      logs and other drilling data, core, pulps, reports, surveys, assays,
      analyses, production reports, operations, technical, accounting and
      financial records, and other Business Information, to the extent preserved

      risk, cost and expense, and subject to reasonable safety regulations, to
      inspect the Assets and Operations at all reasonable times, so long as the
      non-managing JV Participant does not unreasonably interfere with

    ACQUISITIONS
WITHIN AREA OF INTEREST

    

    17.1           General.  Any
interest or right to acquire any interest in real property, mineral rights,
water rights or property rights related thereto within the Area of Interest
(“Rights”) either
acquired or proposed to be acquired during the term of this Agreement by or on
behalf of any Party (“Acquiring
Party”) or any Affiliate of such Party shall be subject to this
Agreement.  For further clarification a reference to “Parties” in this Article
shall mean USE and TCM, and a reference to “Party” shall mean one of
them.  The Parties and their respective Affiliates for their separate
account shall be free to acquire lands and interests in lands outside the Area
of Interest and to locate mining claims outside the Area of
Interest.  Failure of any Affiliate of any Party to comply with this
Article shall be a breach by such Party of this Agreement.

    

    17.2           Notice to Non-Acquiring
Party.  Within 15 days after any acquisition or proposed
acquisition of Rights wholly or partially within the Area of Interest (except
Rights acquired by the Manager pursuant to a Program), the Acquiring Party shall
notify the non-acquiring Party of such acquisition by it or its
Affiliate.  For purposes of this Article, if any of the Rights subject
to acquisition or proposed acquisition fall partially within the Area of
Interest, then all such Rights (i.e., the part within the
Area of Interest and the part outside the Area of Interest) shall be subject to
this Article.  The Acquiring Party’s notice shall describe in detail
the acquisition, the acquiring party if that party is an Affiliate, the lands
and minerals covered thereby, any water rights related thereto, the cost thereof
and the reasons why the Acquiring Party believes that the acquisition or
proposed acquisition of the interest is in the best interests of the Parties
under this Agreement.  In addition to such notice, the Acquiring Party
shall make any and all information concerning the relevant interest available
for inspection by the non-acquiring Party.

    

    17.3           Election
to Acquire.

              During
      the Option Period, within 30 days after receiving the Acquiring Party’s
      notice, the non-acquiring Party may notify the Acquiring Party of its
      election to include such acquired interest in the Property and make it
      subject to the terms of this Agreement.  Upon such election such
      acquired interest shall be included in the Property thereafter for all
      purposes of this Agreement.  If the Acquiring Party is USE, then
      TCM shall reimburse it for the acquisition costs that it or its Affiliate
      has incurred.  When paid by TCM in the first instance on
      acquisition, or reimbursed by TCM when acquired by USE, the acquisition
      costs for any acquired interests will be deemed to constitute Expenditures
      to the credit of TCM hereunder.

              During
      the Joint Venture Period, within 30 days after receiving the Acquiring
      Party’s notice, the non-acquiring Party may notify the Acquiring Party of
      its election to accept a proportionate interest in the acquired interest
      equal to its Participating Interest. Promptly upon such notice, the
      Acquiring Party shall convey or cause its Affiliate to convey to the
      non-acquiring Party, in proportion to its respective Participating
      Interest, by special warranty deed with title held as described in Section
      8.12, all of the Acquiring Party’s (or its Affiliate’s) interest in such
      acquired interest, free and clear of all Encumbrances arising by, through
      or under the Acquiring Party (or its Affiliate) other than those to which
      both

    Parties have agreed.  The
acquired interests shall become a part of the Property for all purposes of this
Agreement immediately upon such notice.  The non-acquiring Party shall
promptly pay to the Acquiring Party its proportionate share of the latter’s
actual out-of-pocket acquisition costs.

     

    17.4           Election to Acquire Not
Exercised.  If the other Party does not give notice to the
Acquiring Party within the 30 day period set forth in Sections 17.3(a) or (b),
it shall have no interest in the acquired interests, and the acquired interests
shall not be a part of the Property or Assets or continue to be subject to this
Agreement, and the Acquiring Party shall be free to hold or deal with the
acquired interest free of the terms of this Agreement, and such acquired
interest shall be excluded from the Area of Interest.

    ABANDONMENT
AND SURRENDER OF PROPERTIES

    

    18.1           Abandonment and Surrender of Property
- Option Period.  During the Option Period, other than as
provided in Section 7.5(b), the Manager may surrender or abandon any Rights
contained in the Property only with the consent of USE.  If USE agrees
with such abandonment or surrender, then the Manager may proceed with such
abandonment or surrender.  If USE does not agree with such abandonment
or surrender, then such Rights shall not be abandoned or
surrendered.

    

    18.2           Abandonment and Surrender of Property
– Joint Venture Period.  During the Joint Venture Period,
either JV Participant may request the Management Committee to authorize the
Manager to surrender or abandon part or all of the Property.  If the
Management Committee does not authorize such surrender or abandonment, or
authorizes any such surrender or abandonment over the objection of either JV
Participant, the JV Participant that desires to surrender or abandon shall
assign to the objecting JV Participant, by special warranty deed and without
cost to the objecting JV Participant, all of the abandoning JV Participant’s
interest in the Property sought to be abandoned or surrendered, free and clear
of all Encumbrances created by, through or under the abandoning JV Participant
other than those to which both JV Participants have agreed.  Upon the
assignment, such properties shall cease to be part of the
Property.  The JV Participant that desires to abandon or surrender
shall remain liable for its share (determined by its Participating Interest as
of the date of such abandonment, after first taking into account any reduction,
readjustment, and restoration of Participating Interests under Sections 8.6,
9.4, 9.5 and 10.5) of any liability with respect to such Property, including,
without limitation, Continuing Obligations, Environmental Liabilities and
Environmental Compliance, whether accruing before or after such abandonment,
arising out of activities prior to the Effective Date and out of Operations
conducted prior to the date of such abandonment, regardless of when any funds
may be expended to satisfy such liability.

    19.2           Dispute
Resolution.  All disputes arising under or in connection with
this Agreement that cannot be resolved by informal negotiation between the
Parties shall be resolved in accordance with Sections 19.3 and
19.4.

    

    19.3           Mediation.  If any
dispute has not been resolved within 30 days after the date of the Notice of a
dispute, or if the Party receiving such Notice fails or refuses to meet within
such time period, either Party may initiate mediation of the dispute by sending
the other Party a written request that the dispute be mediated.  The
Party receiving such a written request shall promptly respond to the requesting
Party so that all Parties can jointly select a neutral and impartial mediator
and schedule the mediation session.  The Parties shall mediate the
dispute before a neutral, third party mediator within 30 days after the date of
the written request for mediation.

    

    19.4           Arbitration.  If a
dispute has not been resolved within 60 days after the original Notice of a
dispute or within 30 days after the date of a request for mediation, whichever
is later, then any Party may initiate arbitration proceedings.  Any
dispute, controversy or claim, of any and every kind or type, whether based on
contract, tort, statute, regulations or otherwise, arising out of, connected
with, or relating in any way to this Agreement, the relationship of the Parties,
the obligations of the Parties or the Operations carried out under this
Agreement, including without limitation, any dispute as to the existence,
validity, construction, interpretation, negotiation, performance,
non-performance, breach, termination or enforceability of this Agreement and
establishment of fair market value, shall be settled through final and binding
arbitration, it being the intention of the Parties that this is a broad form
arbitration agreement designed to encompass all possible disputes among the
Parties relating to the Property and this Agreement.

    

    The
arbitration shall be conducted in accordance with the Arbitration Rules of the
American Arbitration Association (“AAA”) in effect on the date of
commencement of the arbitration proceeding (the “AAA Rules”).  The
arbitration panel shall apply the Federal Rules of Evidence to all evidentiary
questions arising in the course of the arbitration, and shall apply the Federal

              Number of
      Arbitrators.  The Parties shall appoint a sole arbitrator
      agreeable to them to resolve any dispute; provided, however, that should
      the Parties fail to agree upon a sole arbitrator within 30 days after the
      initiation of the arbitration, then there shall be 3 arbitrators. The
      claimant shall name the first arbitrator within thirty days after the
      expiration of the above-described deadline to appoint a single
      arbitrator.  The respondent shall appoint the second arbitrator
      within 30 days after the appointment of the first
      arbitrator.  The two Party-appointed arbitrators shall appoint
      the third arbitrator within thirty days after the appointment of the
      second arbitrator.  If (i) the respondent fails to appoint an
      arbitrator or (ii) the two Party-appointed arbitrators fail to appoint a
      third arbitrator within the above-described time limitations, then the AAA
      shall appoint the second and/or third arbitrator, as

      arbitrator shall have any financial interest (directly or indirectly) in
      the dispute or any financial dependence (directly or indirectly) upon any
      of the Parties.  All arbitrators shall be knowledgeable of the
      mining industry or the law applicable to such business.  The

              Interim
      Measures.  The arbitrators, or in an emergency the
      presiding arbitrator acting alone in the event one or more of the other
      arbitrators are unable to be involved in a timely fashion, may grant
      interim measures including injunctions, attachments and conservation
      orders in appropriate circumstances, which measures the Parties agree may
      be immediately enforced by the arbitrators or by court
      order.  Hearings on requests for interim measures may be held in
      person, by telephone or by video conference, and requests for relief,
      responses, briefs or memorials may be sent to, and orders or awards
      received from, the arbitrators by facsimile or other similar means which
      include a confirmation of delivery.  Notwithstanding the
      requirements for alternative dispute resolution procedures (such as
      negotiation and mediation), prior to the constitution of the arbitration
      tribunal and thereafter as necessary to enforce the arbitrators’ rulings
      or in the absence of the jurisdiction of the arbitrators to rule on
      interim measures in a given jurisdiction, any Party may apply to a court
      for interim measures, and the Parties agree that seeking and obtaining
      such measures shall not waive the right to
  arbitration.

              Costs and Attorney’s
      Fees.  The arbitral tribunal is authorized to award
      attorney’s fees or allocate them between the Parties.  The costs
      of the arbitration proceedings shall be borne in the manner determined by
      the arbitral tribunal, with the exception of the arbitrators’
      fees.  The Parties shall divide the cost of a single arbiter,
      with TCM paying 50% of the fee and the USE paying the remaining
      50%.  In the event that three arbitrators are appointed, each of
      TCM and the USE shall pay the fee of the arbitrator it appoints and 50% of
      the fee of the third arbitrator.

written notice (unless less time is permitted by such rules, regulations or
proceeding) and, in making such disclosure, the disclosing Party shall disclose

      Date without breach of this
Agreement.

            

    

    

    20.6           Public
Announcements.  Prior to making or issuing any press release or
other public announcement or disclosure of Business Information that is not
Confidential Information, a JV Participant shall first consult with the other JV
Participant as to the content and timing of such announcement or
disclosure.  If the other Party from whom such approval is requested

receiving such request, such other Party shall be deemed to have approved the
press release or public statement forming the subject matter of such
request.

    21.4           Waiver.  The failure
of any Party to insist on the strict performance of any provision of this
Agreement or to exercise any right, power or remedy upon a breach hereof shall
not constitute a waiver of any provision of this Agreement or limit such Party’s
right thereafter to enforce any provision or exercise any right.

      for TCM’s obligation to make option payments under Section 5.1(b), the
      obligations of a Party under this Agreement, including TCM’s obligation to
      incur Expenditures under 6.1(a), shall be suspended to the extent and for
      the period that performance is prevented by any cause, whether foreseeable
      or unforeseeable, beyond its reasonable control, including, without
      limitation, labor disputes (however arising and whether or not employee
      demands are reasonable or within the power of the Party to grant); acts of
      God; Laws of any government or governmental entity; ****; acts of war or
      conditions arising out of or attributable to war, whether declared or
      undeclared; riots, protests, civil strife, insurrection or rebellion;
      fire, explosion, earthquake, storm, flood, sink holes, drought or other
      adverse weather condition; accidents; or any other cause whether similar
      or dissimilar to the foregoing.  The affected Party shall
      promptly give notice to the other Party of the suspension of performance,
      stating therein the nature of the suspension, the reasons therefore, and
      the expected duration thereof.  The affected Party shall resume
      performance as soon as reasonably possible.  During a period of
      suspension during the Joint Venture Period, the obligations of both JV
      Participants to advance funds pursuant to Section 10.2 shall be reduced to
      levels consistent with then current Operations.  For the
      avoidance of doubt, this Section 21.6 does not relieve the Manager of its
      obligation to keep the Property in good
  standing.

    21.7           Rule Against
Perpetuities.  The Parties do not intend that there shall be
any violation of the rule against perpetuities, the rule Against unreasonable
restraints on the alienation of property, or any similar
rule.  Accordingly, if any right or option to acquire any interest in
the Property, in a Participating Interest, in the Assets, or in any real
property exists under this Agreement, such right or option must be exercised, if
at all, so as to vest such interest within time periods permitted by applicable
rules and law.  If, however, any such violation should inadvertently
occur, the Parties hereby agree that a court shall reform that provision in such
a way as to approximate most closely the intent of the Parties within the limits
permissible under such rules.

    

    21.8           Further
Assurances.  Each of the Parties shall take, from time to time
and without additional consideration, such further actions and execute such
additional instruments as may be reasonably necessary or convenient to implement
and carry out the intent and purpose of this Agreement or as may be reasonably
required by lenders in connection with Project Financing.

    

    21.9           Entire Agreement; Successors and
Assigns.  This Agreement contains the entire understanding of
the Parties and supersedes all prior agreements and understandings between the
Parties relating to the subject matter hereof, provided, however, that the last
full paragraph on page 3 and the following paragraph beginning on page 3 and
ending on page 4 of the Confidentiality Agreement between the Parties dated
April 24, 2008, concerning the two-year period during which neither Party will
purchase the other Party’s securities or assets, shall survive the execution of
this Agreement, and shall remain in full force and effect.  This
