                        LIMITED LIABILITY COMPANY AGREEMENT

       This  Limited  Liability  Company Agreement  ("Agreement")  is  made  and
  entered into as  of this 6th day of  September, 1996, by and between  Santa Fe
  Pacific  Gold Corporation,  a Delaware corporation  ("SFPG")" and Hecla Mining

  has caused plans and budgets to be prepared  for the development, construction
  and life-of-mine  operation of the  Rosebud Mine (as herein  defined) and SFPG
  has reviewed  such  plans and  budgets.   Hecla  and  SFPG desire  to  jointly
  develop and operate the Rosebud Mine.

       SFPG owns  and operates the Twin  Creeks Plant (as herein  defined). SFPG

  Interest (as herein defined); and  to acquire, own, explore,  manage, operate,
  and dispose of other assets.

       A certificate  of formation for the Company  was filed with the Secretary

  Twin  Creeks Plant  and all  facilities,  processes and  equipment to  be used
  therein, and nothing in  this Agreement  shall be deemed  to obligate SFPG  as
  Manager for Processing to achieve  any specific recovery rate  or efficiencies
  of operation in Processing of Rosebud Ores or Other Ores.

            (g)  Notwithstanding any  other provision of this  Agreement, SFPG's
  obligation to  Process  Rosebud Ores  and  Other  Ores during  the  Processing
  Period as set  forth in this Section 5.3 shall  survive any withdrawal by SFPG
  as  a Member,  the  dissolution of  the  Company, or  the  Transfer of  SFPG's
  Ownership Interest. 


                                     ARTICLE 6





                               INTERESTS OF MEMBERS

            6.1  INITIAL  OWNERSHIP  INTERESTS.   The  Members  shall  have  the
  following initial Ownership Interests:

                                 SFPG -   50.0000%
                                 Hecla -  50.0000%

            6.2  CHANGES IN OWNERSHIP INTERESTS.   A Member's Ownership Interest
  shall be changed as follows: 

            (a)  If a Member makes an  election provided in Sections  6.3(a) and
  10.6;





                                        20




    26

            (b)  If a Member defaults in making its agreed-upon contribution  to
  an Adopted Program and  Budget, followed by an election by the other Member to
  invoke Section 9.6(b) or (c);

            (c)  If a Member's  Ownership Interest is converted to a Net Returns
  Royalty pursuant to Section 6.4;

            (d)  Transfer by  a Member of  less than all  its Ownership Interest
  in accordance with Article 15; or

            (e)  Acquisition of less than all  of the Ownership Interest  of the
  other Member, however arising.  

            6.3  VOLUNTARY  REDUCTION  IN  OWNERSHIP.     A  Member  may  elect,
  consistent with  and limited  by  Section 10.6,  not to  contribute to  or  to
  contribute less  than the percentage  reflected by its  Ownership Interest to:
  (x)  the  Investment Costs  component  of an  Adopted Program  and  Budget for
  Development and  Mining  and the  Investment  Costs  component of  an  Adopted
  Program and Budget  for Processing, or (y)  an Adopted Program and  Budget for
  Exploration.   Any such  election must  be made  in the  same percentage  with
  respect to  the Investment Costs in the Budget  for Development and Mining and
  in the Budget for Processing.

            (a)  If a Member (a "Diluting  Member") elects not to  contribute to
  or to  contribute  a  lesser  amount than  in  proportion  to  its  respective
  Ownership Interest for (i) the Investment  Costs included in the Budget of  an
  Adopted  Program and Budget for Development  and Mining and for the Investment
  Costs included in the Budget of an Adopted  Program and Budget for Processing,
  or  (ii) to  an  Adopted Program  and Budget  for  Exploration, and  the other
  Member elects to  fund its  proportionate share  and all  or any  part of  the
  Diluting Member's share of such costs, the  Ownership Interest of the Diluting
  Member  shall be  provisionally recalculated as  of the effective  date of the
  Adopted Program and Budget, according to the following formula:  

                      R    =    DB(M) x 100%
                                ------
                                DB(AM)

                 Where:

                      R         =
            The recalculated Ownership Interest of the Diluting Member.

                      DB(M)     =
            The  Dilution Base  of  each  Member,  which  shall  be  Twenty-Nine
            Million Dollars ($29,000,000)  plus the amounts of  cash contributed
            to  the Company  by the  Member for  Investment Costs  (but not  for
            Operational Costs)  and for Exploration,  but excluding all  amounts
            contributed to the 


                                        21







    27

            Company or expended by the  Member to satisfy its  obligations under
            Section 5.2,  with adjustments to  such amounts by  crediting to the
            contribution by Hecla  and deducting from the contributions  by SFPG
            (solely for the  purpose of this calculation) fifty percent (50%) of
            the first  One Million  Dollars ($1,000,000)  that SFPG  contributes
            for Exploration  pursuant to Section  5.2(c) and thereafter  twenty-
            five percent (25%)  of all monies SFPG contributes  for Exploration,
            and as adjusted  for anticipated contributions for  Investment Costs
            based on the  Adopted Programs and Budgets and the Diluting Member's
            election as to contributions.  

                      DB(AM)    =
            The  Dilution  Base of  all  Members,  which  shall  be Fifty  Eight
            Million Dollars  ($58,000,000) plus the  amounts contributed to  the
            Company  by   all  Members  for  Investment   Costs  (but   not  for
            Operational Costs)  and for Exploration,  but excluding all  amounts
            contributed to the  Company or expended  by the  Members to  satisfy
            their  obligations  under  Section 5.2,  with  adjustments  to  such
            amount  by crediting  to the  contributions  by Hecla  and deducting
            from  the contributions  by  SFPG (solely  for  the purpose  of this
            calculation) fifty  percent (50%) of  the first One Million  Dollars
            ($1,000,000)  that  SFPG contributes  for  Exploration  pursuant  to
            Section  5.2(c) and  thereafter  twenty-five  percent (25%)  of  all
            monies  SFPG  contributes  for  Exploration,  and  as  adjusted  for
            anticipated contributions for Investment  Costs and for  Exploration
            based on the Adopted Program  and Budget and all  Members' elections
            as to contributions.

            The  Ownership  Interest   of  the  non-Diluting  Member   shall  be
  provisionally increased  by  the amount  of  the  reduction in  the  Ownership
  Interest of the Diluting Member.   The recalculations made under this  Section
  shall be  provisional and subject to the  final adjustments provided for under
  Subsection  6.3(c) and  (d).   If  the other  Member elects  not  to fund  any
  portion of  the Diluting Member's  deficiency, the Ownership  Interests of the
  Members shall  not be recalculated, and  the Manager having control  over such
  Adopted Program and Budget shall prepare and submit  to the Manager for Mining
  for presentation to  the Management Board  in accordance  with the  procedures
  specified in Section 10.3 a revised proposed Program and Budget. If the  other
  Member  elects to fund a  portion, but not the  entire amount, of the Diluting
  Member's  deficiency,  the  Ownership  Interests  of   the  Members  shall  be
  provisionally recalculated, and the  Manager having control over such  Adopted
  Program and  Budget shall  reduce the relevant  Program and Budget  to reflect
  the funds available.

            (b)  Within  thirty (30)  days after  the conclusion  of an  Adopted
  Program and Budget with respect to which a Member's 



                                        22










    28

  Ownership  Interest  was  provisionally  reduced  under  Section  6.3(a),  the
  Manager  having control over  such Adopted Program and  Budget shall report to
  the  Diluting Member the  total amount  of money  expended and accrued  by the
  Manager for such  Adopted Program and  Budget upon  which the Diluting  Member
  made the election under Section 6.3(a).

            (c)  Unless Section  6.3(d) is  applicable,  the Members'  Ownership
  Interests  shall be recalculated pursuant  to Section  6.3(a), by substituting
  each Member's actual contribution  to such Adopted Program and  Budget for and
  in lieu of  the Members' estimated contributions  at the time of  the Diluting
  Member's  election  under  Section  6.3(a).   Recalculation  of  the  Members'
  Ownership Interests  shall be effective as of the  date of commencement of the
  relevant Adopted Program and Budget.

            (d)  If  the Manager  expended or incurred  obligations of less than
  seventy-five  percent  (75%) of  (i)  the  Investment  Costs  included in  the
  Budgets of an  Adopted Program and Budget for Development and Mining and in an
  Adopted Program and Budget  for Processing,  or (ii) the  Budget of a  Program
  and Budget  for Exploration,  as  the case  may be,  with respect  to which  a
  Diluting Member made an  election under Sections 6.3(a) and 10.6 to reduce its
  contribution, within  ten  (10) days  of  receiving  the Manager's  report  on
  expenditures, as provided  in Section 6.3(b)  the Diluting  Member may  notify
  the other Member  of its  election to restore  its Ownership  Interest to  its
  amount  prior to such  election.   If the  Diluting Member makes  the election
  provided  for  in   the  first  sentence  of  this   Subsection  and  the  Net
  Reimbursement Amount  is a  positive number,  it  shall within  ten (10)  days
  thereafter pay  to the  other Member  the Net  Reimbursement Amount.   If  the
  Diluting Member makes the election provided for in  the first sentence of this
  Section  and  the Net  Reimbursement Amount  is a  negative number,  the other
  Member shall within  ten (10) days thereafter  pay to the Diluting  Member the
  Net Reimbursement Amount.


            The "Net Reimbursement Amount" shall mean: 

            the difference  between  the Diluting  Member's proportionate  share
            (at  the Diluting  Member's  former  Ownership Interest  before  the
            current period's election under Sections  6.3(a) and 10.6 was  made)
            of the actual amount expended  or accrued for such  Investment Costs
            or to  Adopted Program and Budget  for Exploration, as the  case may
            be, and the amount actually  contributed by the Diluting  Member for
            such Investment Costs  or to the Program and Budget for Exploration,
            as  the case may  be, plus  interest accruing  thereon at  the Prime
            Rate from the date of contribution by the other Member, 
            less 




                                        23









    29

            the  difference between  the Diluting  Member's  proportionate share
            (at  the Diluting  Member's  former  Ownership Interest  before  the
            current period's election under Sections  6.3(a) and 10.6 was  made)
            of the  value of  any distributions  (the "Value of  Distributions")
            resulting  from  Operations  conducted  pursuant   to  the  relevant
            Program and Budget and the Value of Distributions actually  received
            by the Diluting Member resulting  from Operations conducted pursuant
            to the relevant Program and Budget.

            "Value of  Distributions"  shall  mean  the  sum  of  the  Value  of
  Products, cash and the fair market value  of any other Distributions resulting
  from the Operations conducted pursuant to the Adopted Program and Budget.

            For purposes  of this Subsection,  the amount of  the Budget against
  which  the seventy-five  (75%) criterion is  applied shall  be reduced  to the
  extent  that the  non-Diluting Member  elected to  fund less  than the  entire
  deficiency of  the  Diluting  Member.    Reimbursement  of  the  other  Member
  pursuant to  this  Subsection shall  restore  the  Ownership Interest  of  the
  Diluting Member to its  position prior to  the election under Sections  6.3(a)
  and 10.6.   Restoration of the  Diluting Member's Ownership  Interest shall be
  effective  as  of the  date  of  the  Diluting  Member's payment  of  the  Net
  Reimbursement Amount  to the other  Member and shall  not effect the  Members'
  Capital Accounts under Section 11.12. 

            6.4  CONVERSION  OF  MINORITY  INTEREST.  If  a  Member's  Ownership
  Interest is reduced to  fifteen percent  (15%) or less,  such Member shall  be
  deemed to have withdrawn  as a Member from the  Company and shall Transfer  to
  the  other Member  or  its designee  the  withdrawn Member's  entire Ownership
  Interest,  free and  clear of  any Encumbrances  arising by,  through or under
  such Member, except any  such Encumbrances listed in Subparagraphs  1.2 or 2.2
  of Exhibit A.   Upon the withdrawal of a Member  pursuant to this Section, the
  Company shall convey  to the withdrawn Member  a two percent (2%)  Net Returns
  Royalty, calculated and payable as provided in Exhibit D.

            6.5  CONTINUING   LIABILITIES   UPON   ADJUSTMENTS   OF    OWNERSHIP
  INTERESTS.   No  reduction  or elimination  of  a Member's  Ownership Interest
  under this  Article 6  or the  withdrawal of  a Member  under Section  17.1(b)
  shall  relieve such Member  of its  share of  any Company Liability  or Member
  Liability,   including,   without   limitation,   liability   for   Continuing
  Obligations,  Environmental Liabilities and  Environmental Compliance, whether
  arising before  or after  such reduction,  elimination or  withdrawal, out  of
  acts,  omissions or circumstances occurring prior to  this Agreement or out of
  Operations  conducted during  the term  of this  Agreement but  prior to  such
  reduction, elimination  or withdrawal,  regardless of  when any  funds may  be
  expended to satisfy  such liability, taking into account the limited liability
  provided by the Act.  For purposes of 


                                        24











    30

  this Article 6,  such Member's share of such liability, if any, shall be equal
  to its  Ownership  Interest at  the  time the  act,  omission or  circumstance
  giving rise to such  liability occurred  (or, as to  such liability for  acts,
  omissions or  circumstances prior  to the  effective date  of this  Agreement,
  such Member's  initial Ownership  Interest).   Should the  cumulative cost  of
  satisfying  Continuing Obligations be in excess  of cumulative amounts accrued
  in the Reclamation  Account, each Member shall be liable for its proportionate
  share (i.e., its Ownership Interest  at the time act, omission or circumstance
  giving  rise to  such  liability  occurred) of  the  cost of  satisfying  such
  obligations, whether  or not  one or  more Members  has previously  withdrawn,
  reduced its interest or had its interest converted to a Net Returns Royalty.

            6.6  GRANT  OF  SECURITY  INTERESTS.     Immediately  following  the
  execution of this Agreement and  the completion of the  contributions provided
  for in Section  5.1, the Members shall  cause the Company to execute  the Deed
  of  Trust attached  hereto  a Exhibit  T and  the Security  Agreement attached
  hereto  as Exhibit  U  and each  Member shall  execute  a Pledge  and Security
  Agreement  attached   hereto  as  Exhibit   V  (collectively,  the   "Security
  Agreements").  The Manager for Mining shall promptly  record the Deed of Trust
  in the  real property records of  Humboldt and Pershing Counties,  Nevada, and
  make  all filings and take such other  actions as are necessary to perfect and
  maintain the security interests created  by the Security Agreements  and shall
  furnish evidence of such actions to the Members.


                                     ARTICLE 7

                                 MANAGEMENT BOARD





            7.1  MANAGEMENT.   The  Members  shall  act through  the  Management
  Board, and all acts and meetings of the  Management Board shall constitute the
  acts and meetings of the Members.  The ultimate responsibility  for management
  of  the business and  affairs of  the Company  shall reside in  the Management
  Board,  the Company  shall  be regarded  as  managed by  its  Members for  all
  purposes  of the  Act, and  no statutory  managers shall  be  deemed appointed
  under the Act.  Except as otherwise delegated to the Managers, the  Management
  Board shall have exclusive authority to determine all matters  related to this
  Agreement.    Although the  Mangers  have  day-to-day  responsibility for  the
  matters described in  this Section 7.1,  the ultimate  control of all  matters
  shall be within the absolute control of the Management Board.

            Notwithstanding the  foregoing, but subject  to the limitation  that
  no statutory  manager shall be deemed appointed  under the Act, the day-to-day
  responsibility  for  the  Company's Operations  relating  to  Development  and
  Mining shall reside with 



                                        25









    31

  Hecla, as  Manager  for Mining,  and  the  day-to-day responsibility  for  the
  Company's Operations relating to Processing and  Exploration shall reside with
  SFPG, as  Manager for Processing  and Manager for  Exploration.  In  addition,
  the Manager  for Mining  shall have  the additional  responsibilities for  the
  Company's administration and  for the coordination  of the  activities of  the
  Manager  for Exploration set  forth in  Article 8.   Except for  situations in
  which  the approval  of  the Management  Board  or  the Members  is  expressly
  required by  this Agreement or by nonwaivable provisions  of applicable Law or
  is otherwise  provided for in  this Agreement, but  subject to the  limitation
  that no  statutory manager shall  be deemed appointed  under the Act, each  of
  the  Managers shall, with  respect to  its areas of  responsibility, have full
  and  complete  authority, power  and  discretion  to  manage  and control  the
  business,  affairs  and properties  of  the  Company,  to  make all  decisions
  regarding those matters  and to perform any  and all other acts  or activities
  customary or incident to the management of the Company's business.  

            7.2  ORGANIZATION  AND COMPOSITION  OF THE  MANAGEMENT  BOARD.   The
  Members hereby  establish  a Management  Board  to  determine, except  to  the
  extent  such powers  are  expressly reserved  to  the  Members in  Article  9,
  overall  policies, objectives,  procedures,  methods  and actions  under  this
  Agreement.   The Management  Board shall  consist of  two (2)  representatives
  appointed by  SFPG  and two  (2) representatives  appointed  by Hecla.    Each
  Member may appoint one  or more alternates to act in  the absence of a regular
  Management  Board representative.  Any  alternate so acting  shall be deemed a
  member  of   the  Management   Board.    Appointments   of  Management   Board
  representatives by a Member  shall be made or changed  by Notice to the  other
  Member.

            7.3  DECISIONS.   Other  than  as  provided  in  Section  7.6,  each
  Member,  acting through  its  appointed  Management Board  representatives  in
  attendance at the  meeting, shall have the  number of votes on  the Management
  Board  equal  to its  Voting  Interest.   Unless  otherwise  provided in  this
  Agreement, a majority vote of the  Management Board shall be required for  all
  decisions of the Management Board.

            7.4  MEETINGS.   

            (a)  The  Management Board  shall  hold  regular meetings  at  least
  quarterly  in Winnemucca, Nevada,  or at  other agreed places.  Members of the
  Management Board may participate in  such meetings by telephone.   The Manager
  for Mining shall give  thirty (30) days Notice to the  Members of such regular
  meetings.   Additionally, either Member  may call a  special meeting upon  ten
  (10) days  Notice to the  other Member.  In  case of an  emergency, reasonable
  notice  of a special  meeting shall  suffice.  There  shall be a  quorum if at
  least one member  representing each Member is present; provided, however, that
  if a  Member fails to  attend two  (2) consecutive  properly called  meetings,
  then a quorum shall exist if the other 



                                        26









    32

  Member is  represented by  its appointed  member, and  a vote  of such  Member
  shall be considered  a majority vote  for the purposes of  the conduct of  all
  business properly noticed and not requiring a unanimous vote.

            (b)  If  business cannot  be  conducted  at  a  regular  or  special
  meeting due  to the  lack of a  quorum, any Member  may call the  next meeting
  upon ten (10) days Notice to the other Member.    

            (c)  Each  Notice  of a  meeting  shall include  an  itemized agenda
  prepared by  the Manager for Mining  in the case of  a regular meeting,  or by
  the Member calling  the meeting  in the  case of  a special  meeting, but  any
  matters may be considered if a  Member adds the matter to the  agenda at least
  two (2)  business days  before the meeting  or with  the consent of  the other
  Member.  The  Manager for  Mining shall prepare  minutes of  all meetings  and
  shall distribute copies  of such minutes to  the Members within ten  (10) days
  after the meeting.   The other Member shall sign  and return or object  to the
  minutes  prepared by  the Manager  for  Mining within  thirty (30)  days after
  receipt, and failure  to do either shall  be deemed acceptance of  the minutes
  as prepared  by the Manager  for Mining.   The minutes, when signed  or deemed
  accepted by all  Members, shall be the  official record of the  decisions made
  by the  Management Board.  Decisions made at  a Management Board meeting shall
  be implemented in accordance  with Adopted Programs and Budgets.   If a Member
  timely  objects   to  minutes  proposed   by  the  Manager   for  Mining,  the
  representatives of  the  Management Board  shall  seek, for  a  period not  to
  exceed  thirty (30) days after receipt by the  Manager for Mining of Notice of
  the objections,  to agree  upon minutes  acceptable to  all Members.   If  the
  Management  Board does  not  reach agreement  on the  minutes  of the  meeting
  within such thirty (30) day period, the minutes of  the meeting as prepared by
  the  Manager for  Mining  together with  the  other Member's  proposed changes
  shall  collectively  constitute the  record  of  the  meeting.   If  personnel
  employed in  Operations are  required to  attend a  Management Board  meeting,
  reasonable costs incurred  in connection with such attendance shall be charged
  to the Company.  All other costs shall be paid by the Members individually.

            7.5  ACTION  WITHOUT  MEETING.   With  the  consent  of  all of  the
  Members'  representatives on  the Management  Board, the  Management Board may
  hold meetings  by telephone, provided all  decisions are immediately confirmed
  in writing by the representatives.

            7.6  MATTERS  REQUIRING   SPECIAL  APPROVAL  OF   MANAGEMENT  BOARD.
  Notwithstanding  any other provision of  this Agreement, the following matters
  shall require  the approval  of  seventy percent  (70%) of  all votes  of  the
  Management Board:






                                        27










    33

            (a)   any  Program and  Budget  for Development  and  Mining or  for
  Processing  which includes  Investment  Costs  exceeding Six  Million  Dollars
  ($6,000,000);

            (b)    any Program  and  Budget  for  Development  and Mining  which
  includes costs for Development exceeding Three Million Dollars ($3,000,000);

            (c)  any  Program and Budget for Exploration exceeding Three Million
  Dollars ($3,000,000);

            (d)   any  decision to  temporarily  (except as  a  result of  Force
  Majeure or an emergency) or permanently close the Rosebud Mine;

            (e)   any decision to change the place  at which the Rosebud Ores or
  Other  Ores  are  Processed  from  the  Twin  Creeks  Plant  to  an  Alternate
  Processing Plant; or

            (f)   any  decision to  temporarily  (except as  a  result of  Force
  Majeure or  an emergency) or permanently close the  Twin Creeks Plant prior to
  the expiration of the Processing Period.

            7.7  ACTIVITIES DURING DEADLOCK.   If the Management  Board for  any
  reason  fails to  adopt a  Program  and Budget,  the  Managers shall  continue
  Operations  at levels  comparable  with the  last  Adopted Program  and Budget

  the Company its proportionate share of  the Cash Call.  The Manager for Mining
  shall at all times maintain a cash balance approximately equal to  the rate of

            (b)  If a  Member fails to meet Cash Calls  in the amount and within
  the  time specified  in Section 8.4(a),  the amount not  timely contributed to
  the Company shall bear interest from  the date due at an annual rate equal  to

  Member if the other  member elects to invoke Section 9.6(c).   The Manager for
  Mining shall immediately notify both Members if either Member  fails to timely
  pay a Cash Call and  the other Member shall have those other rights, remedies,
  and elections specified in Sections 9.6 and 9.7.

            8.5  LIMITED AUTHORITY TO  BIND COMPANY.  Unless authorized to do so
  by this  Agreement or by  the Management Board,  no attorney-in-fact, employee
  or other agent  of the Company shall  have any power or authority  to bind the
  Company in any  way, to pledge its  credit or to render it  liable pecuniarily
  for any purpose.   No Member  shall have any  power or authority  to bind  the
  Company unless the  Member has been  authorized by the  Managers to act  as an
  agent of the Company in accordance with the previous sentence.

            8.6  LIABILITY FOR CERTAIN ACTS, INDEMNITIES.  

            (a)  The Managers do  not, in any way,  guarantee the return  of the
  Members' Capital  Contributions or a  profit for the  Members from Operations.
  Subject to the provisions of Sections 4.6, through 4.10  and Section 10.7, the
  Managers shall not be liable to  the Company or to any Member for any  loss or
  damage sustained  by the  Company or  any Member,  unless the  loss or  damage
  shall have been the result of  such Manager's fraud, deceit, gross  negligence
  or willful misconduct.

            (b)  Subject to the provisions of Section 8.6(a), the  Company shall
  indemnify  the Managers and  their officers,  directors, employees  and agents
  for, and hold them harmless from, any 



                                        36









    42

  liability, whether  civil  or criminal,  and  any  loss, damage,  or  expense,
  including reasonable  attorneys' fees, when  acting for  or on  behalf of  the
  Company.   In connection  with such  indemnification, the  Company shall  make
  advances for expenses  to the  maximum extent permitted  under the  Act.   The
  Company  shall similarly indemnify its employees  and other agents who are not
  Managers to  the fullest  extent permitted  by Law.   The  termination of  any
  action,  suit or  proceeding by  judgment,  order, settlement,  conviction, or
  upon a plea of NOLO CONTENDERE or its equivalent  shall not of itself create a
  presumption that indemnification  is not available hereunder.   The obligation
  of the Company  to indemnify any Manager  hereunder shall be satisfied  out of
  the Assets only, and if the Assets are insufficient to satisfy its  obligation
  to indemnify any Manager,  such Manager shall not be  entitled to contribution
  from any Member.

            8.7  MANAGERS AND MEMBERS  HAVE NO EXCLUSIVE  DUTY TO  COMPANY.   To
  the extent  permitted under  the Act, the  Managers shall  not be required  to
  manage the Company  as their  sole and exclusive  function and  they may  have
  other business  interests and may  engage in  other activities in  addition to
  those relating to the Company.  Neither the Company nor any  Member shall have
  any right, by  virtue of this Agreement, to share or participate in such other
  investments  or  activities of  any  Manager or  Member  or to  the  income or
  proceeds  derived therefrom.  Neither the  Managers nor any Member shall incur
  any liability to the Company or  to any of the Members as a result of engaging
  in any other business or  venture.  Notwithstanding the foregoing  the conduct
  of or involvement in other  business by a Member  (i) shall be conducted in  a
  manner  such  that  it  does  not  interfere  with  the  performance  of  this
  Agreement; and (ii) shall not excuse any breach of this Agreement

            8.8  BANK ACCOUNTS.  The  Manager for Mining  may from time to  time
  open bank  accounts in the  name of  the Company, and  the Manager  for Mining
  shall be  the sole signatory  thereon, unless the  Management Board determines
  otherwise.    Notwithstanding the  foregoing,  the  Manager  for Mining  shall
  establish  a  separate   interest  bearing  account  into   which  all   funds
  contributed  by  the  Members  for  reclamation  (other  than  funds  used  in
  concurrent  reclamation  activities)  shall  be  deposited  (the  "Reclamation
  Account").   The  authorization of all  Members, which  shall not  be withheld
  unreasonably, shall be  required for withdrawals from the Reclamation Account.

            8.9  RESIGNATION.   The  Manager  for  Mining and  the  Manager  for
  Exploration  may resign  at  any time  by giving  Notice  to the  Members. The
  Manager for Processing may resign at any time after  the end of the Processing
  Period  by giving Notice to the Members.  The resignation of any Manager shall
  take effect thirty (30) days after  receipt of Notice thereof or at such later
  time  as shall be  specified in  such Notice; and,  unless otherwise specified
  therein, the acceptance of such resignation shall not be necessary to make 



                                        37










    43

  it  effective. The  resignation of a  Manager who  is also a  Member shall not
  affect the  resigning Manager's  rights or status  as a  Member and shall  not
  constitute  a withdrawal  of a  Member.   If a  Manager commits  any  Event of
  Default, other than the failure to pay timely a Cash Call  or to repay a Cover
  Payment  Loan on  demand the Manager  shall be  deemed to  have resigned  as a
  Manager.

            8.10 REMOVAL.  At a special  meeting of the Management  Board called
  expressly for  that purpose,  any Manager  may be  removed at  any time for  a
  material breach  of its responsibilities  as Manager under  this Agreement, if
  such breach  remains uncured at  the time of  the meeting, by the  affirmative
  vote  of Members  holding a  majority of  the  Voting Interests  including any
  Voting Interest  held by the Manager or an  Affiliate of the affected Manager.
  The removal of a  Manager who is also  a Member shall  not affect the  removed
  Manager's rights or status as a  Member and shall not constitute a  withdrawal
  of a  Member.   If  SFPG is  removed  as Manager  for  Processing as  provided
  herein,  the Company shall  have no right to  have Rosebud Ores  or Other Ores
  Processed at the  Twin Creeks Plant or  at any Alternate Processing  Plant and
  all obligations of SFPG with respect to  Processing under this Agreement shall
  be terminated  by such removal;  but SFPG shall  remain liable to the  Company
  for any and all damages  caused by the unavailability of the Twin Creeks Plant
  or an Alternative  Processing Plant to Process  Rosebud Ores or Other  Ores to
  the extent that  Section 5.3 of this  Agreement requires SFPG to  Process such
  ores.

            8.11 VACANCIES  AND REPLACEMENTS.   Any  vacancy  occurring for  any
  reason in the office of the Manager for Mining,  the Manager for Processing or
  the  Manager for  Exploration  shall be  filled  by  the affirmative  vote  of
  Members holding a majority of  the Voting Interest (determined  without regard
  to any Voting Interest owned by  a Manager who resigned or was removed  during
  the preceding twenty-four (24)  month period).  Notwithstanding the foregoing,
  (a) if  the Ownership Interest  of Hecla declines  to thirty percent (30%)  or
  less, SFPG  shall, in its sole discretion, have  the right to replace Hecla as
  Manager for Mining  by designating itself as  the Manager for Mining;  and (b)
  if the Ownership  Interest of SFPG declines  to thirty percent (30%)  or less,
  Hecla shall,  in  its sole  discretion,  have the  right  to replace  SFPG  as
  Manager for Exploration by designating itself as the Manager for Exploration.

            8.12 COMPENSATION, REIMBURSEMENT, ORGANIZATION EXPENSES.

            (a)  The compensation  of the Managers, if any, shall  be fixed from
  time to time by the Management Board.

            (b)  The  Managers shall cause  the Company  to make an  appropriate
  election to treat the  expenses incurred by the Company in connection with the
  formation and  organization of  the Company  to be amortized  under the  sixty
  (60)  month  period beginning  with  the  month in  which  the Company  begins
  business to the extent that such 



                                        38








    44

  expenses  constitute  "organizational  expenses" of  the  Company  within  the
  meaning of Section 709(b)(2) of the Code.

            8.13 RIGHT TO RELY ON THE MANAGERS.  Any  Person  dealing  with  the
  Company  may rely (without duty of further  inquiry) upon a certificate signed
  by any Manager as to:

            (a)  The identity of any Manager or Member;

            (b)  The existence  or  nonexistence  of any  fact  or  facts  which
  constitute a  condition precedent  to acts  on behalf  of the  Company by  any
  Manager or  which  are in  any  other manner  germane to  the  affairs of  the
  Company;

            (c)  The  Persons who  are  authorized to  execute  and deliver  any
  instrument or document of the Company; or

            (d)  Any act or  failure to act by  the Company or any  other matter
  whatsoever involving the Company or any Member. 


                                     ARTICLE 9

                         RIGHTS AND OBLIGATIONS OF MEMBERS

            9.1  LIMITATION  OF   LIABILITY.     Except  as   provided  by   the
  nonwaivable provisions of  the Act and by  this Agreement, no Member  shall be
  liable  for an obligation of the  Company solely by reason  of being or acting
  as a Member.

            9.2  LIST  OF MEMBERS.    Upon written  request  of any  Member, the
  Management  Board  shall provide  a  list  showing  the  names, addresses  and
  Ownership Interests of all Members.

            9.3  APPROVAL OF SALE OF  ALL ASSETS.   The affirmative vote of  one
  hundred percent  (100%) of Voting Interests  of all Members  shall be required
  to approve the sale,  exchange or other disposition  of all, or  substantially
  all,  of the  Company's  assets (other  than  in the  ordinary  course of  the
  Company's business)  which is  to occur  as part  of a  single transaction  or
  plan.

            9.4  COMPANY  BOOKS.   The  Manager for  Mining  shall have  overall
  responsibility  for  maintaining  the  Company's books  and  records  and  for
  providing accounting  services  to  it.    The  Managers  shall  maintain  and
  preserve, during the term of the  Company, and for five (5) years  thereafter,
  all  accounts,  books,  and   other  relevant  Company  documents  related  to
  financial, environmental,  regulatory, operational  and other  matters.   Each
  Member shall have  the right to request  in writing that all  accounts, books,
  and other relevant Company documents be maintained for a longer period at  the
  requesting Member's cost.  Upon reasonable request, each Member 



                                        39







    45

  shall have  the right,  during ordinary  business hours, to  inspect and  copy
  such Company documents at the requesting Member's expense.

            9.5  PRIORITY AND RETURN  OF CAPITAL.  No Member shall have priority
  over any other Member, either as to the return of Capital Contributions or  as
  to net  profits, net losses or  distributions; provided that this  Section 9.5
  shall not apply to loans  (as distinguished from Capital  Contributions) which
  a Member has made to the Company.

            9.6  RIGHTS ON FAILURE OF A MEMBER TO PAY A CASH CALL.
            (a)   If  a  Member fails  to  pay  a Cash  Call  within the  period
  specified in Section 8.4:

            (i)  The other Member may make, but shall not be obligated to  make,
            a  Cover Payment on  behalf of  the Member  failing to pay  the Cash
            Call.  Each  and every Cover Payment  will constitute a  demand loan
            bearing interest from the  date of the advance at the  rate provided
            in Section 8.4(b) (a "Cover Payment Loan").  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.  

            (ii) The right of the  Member to take and receive a  Distribution of
            Products in  kind pursuant  to Section 11.5(b)  shall be  suspended.
            If the other  Member has made a  Cover Payment Loan with  respect to
            the defaulted  Cash  Call, it  shall  have  the right  to  sell  the
            defaulting  Member's share  of Products  in  any reasonable  manner,
            subject to the obligation to pay any  royalty due thereon, and apply
            the  net proceeds of  such sale to the  balance due  under the Cover
            Payment Loan,  including interest and costs.   The right of a Member
            that has defaulted with  respect to a Cash Call to  take and receive
            a Distribution of Products in kind  shall be reinstated, if at  all,
            when all amounts  due with respect  to the defaulted  Cash Call  and
            Cover Payment Loan and any interest or  other costs due with respect
            thereto have been  discharged. If a  Member exercises  its right  to
            take  and receive  another Member's  Distribution  of Products,  the
            Member originally  entitled to  such Products  shall  be treated  as
            having taken such Products  and sold them, with the proceeds of such
            sale being used to repay the Cover Payment Loan.

            (b)  If a Member fails  to timely pay a Cash Call or  fails to pay a
  Cover  Payment Loan on  demand, and  the defaulting  Member has not  cured the
  default by  paying the Cash  Call and/or  the Cover  Payment Loan,  (including
  through the  application  of  the  proceeds of  any  sales  of  Products  made
  pursuant to  Subsection 9.6(a)(i)) within ninety  (90) days after the  date on
  which the Cash Call or Cover 



                                        40








    46

  Payment Loan was  due, the other Member  may elect, on not less  than ten (10)
  days Notice to the defaulting Member, one of the following:

            (i)    To have  the defaulting Member  deemed to have resigned  from
            the  Company  and to  have  automatically  made  a  Transfer of  its
            Ownership Interest  to the  non-defaulting Member  or its  designee,
            but  such  defaulting Member  shall  remain  liable for  its  Member
            Liability, if  any; provided, however,  the defaulting Member  shall
            have the right to receive only from two percent (2%) of Net  Returns
            thereafter received by the Company, if  any, and not from any  other
            source,  an  amount  equal to  seventy-five  percent  (75%)  of  the
            defaulting Member's Dilution  Base as of  the date  of the  default.
            Upon receipt  of such amount, the  withdrawn Member shall thereafter
            have no further rights or interests with respect to the Company.

            (ii)   To  purchase  all the  Ownership  Interest of  the defaulting
            Member at  a purchase  price equal  to eighty percent  (80%) of  the
            fair market value  thereof (without regard to  any Member Liability)
            as determined by  a qualified independent appraiser appointed by the
            non-defaulting Member (or,  if the defaulting Member objects  to the
            person  so  appointed  within  ten (10)  days  of  receiving  Notice
            thereof, then  by an independent  and qualified appraiser  appointed
            by  the  joint  action  of  the  appraiser  appointed  by  the  non-
            defaulting Member and  a qualified  independent appraiser  appointed
            by the defaulting Member; provided, however,  that if the defaulting
            Member  fails to  designate a  qualified  independent appraiser  for
            such purpose  within  ten (10)  days  of  such objection,  then  the
            person  originally  designated by  the  non-defaulting  Member shall
            serve as  the appraiser;  provided further,  that if the  appraisers
            appointed by  each of the Members fail  to appoint a third qualified
            independent appraiser within  five (5)  days of  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  of Nevada  upon
            the application of  either Member).   There shall  be withheld  from
            the  purchase  price  payable,  upon   Transfer  of  the  defaulting
            Member's  Ownership Interest,  the  amount  of indebtedness  of  the
            defaulting Member  owing to  the non-defaulting  Member  and to  the
            Company together  with unpaid interest  accrued thereon to the  date
            of  such  transfer;  provided  further,   that  the  purchase  price
            determined  by  the  appraiser  shall  not  take  into  account  any
            minority or marketability discounts.

    47

            (c)  Upon  the deemed resignation of a Member or the purchase of its
  Ownership  Interest pursuant  to Section 9.6(b),  the defaulting  Member shall
  remain liable for  any Member Liability, including without limitation any such
  liability arising from  Environmental Liabilities, Continuing Obligations  and
  Environmental Compliance.   In addition to the  rights provided in Article  9,
  if   a Member fails timely to  pay a Cash Call or to  pay a Cover Payment Loan
  on demand, or comments any material breach of this Agreement not cured  within
  any cure period herein provided,  the non-defaulting Member may  also exercise
  any other rights and remedies available to it under Section 9.7 or under Law.

            9.7  DEFAULTS AND REMEDIES.

            (a)  The circumstances constituting an "Event  of Default" under the
  Pledge and Security  Agreement, Exhibit V, shall  also constitute an  Event of
  Default under this Agreement.

            (b)  Upon the occurrence  of an Event of Default, the non-defaulting
  Member shall  have all of the  rights and remedies  available to it  under the
  Security Agreements.


                                    ARTICLE 10

                               PROGRAMS AND BUDGETS

            10.1 INITIAL PROGRAMS AND BUDGETS.  The Members hereby adopt:

            (a)  The  Mine  Construction Program  and Budget  (but only  for the
  period  through December  31, 1997  insofar  as it  covers Mining),  which was
  prepared by the Manager for Mining, a copy of which is attached as Exhibit I;

            (b)  The  initial Program  and  Budget  for Exploration,  which  was
  prepared  by the  Manager  for Exploration,  a copy  of  which is  attached as
  Exhibit K; and

            (c)  The Plant  Construction Program  and Budget  (but only for  the
  period through December 31,  1997 insofar as it covers Processing),  which was
  prepared  by the  Manager  for Processing,  a  copy of  which  is attached  as
  Exhibit J.

            10.2 OPERATIONS  PURSUANT  TO  PROGRAMS  AND  BUDGETS.    Except  as
  otherwise provided in Sections 10.7  and 10.8, Operations shall  be conducted,

  Adopted Programs and Budgets.  

            10.3 PREPARATION   AND   PRESENTATION  OF   PROGRAMS   AND  BUDGETS.
  Annually, on  or before  October 1,  the Manager  for Mining  shall prepare  a
  proposed Program and Budget for Development and

    48

  Mining, the  Manager  for Processing  shall  prepare  a proposed  Program  and
  Budget  for  Processing, and  the  Manager  for  Exploration  shall prepare  a
  proposed  Program and  Budget  for Exploration.    In preparing  each proposed
  Program and Budget  for Exploration, the Manager for Exploration shall consult
  with a knowledgeable  geologist concerning the Rosebud Mine whom is designated
  by the  Manager for Mining.  Each proposed  Program and Budget for Development
  and Mining and  each proposed Program and Budget for Exploration shall include
  a  cash  accrual  for  all  reasonably  anticipated  reclamation  costs.    In
  preparing the  proposed Budgets, the  Manager for Mining  and the Manager  for
  Processing  shall confer  concerning their  respective  proposed Programs  and
  Budgets so that  timing and  nature of production  of Rosebud  Ores and  Other
  Ores and the availability of Processing capacity at the Twin Creeks Plant  are
  reasonably  coordinated.   Each  Program  and  Budget  for  Processing or  for
  Development  and Mining  shall specifically  identify  those elements  thereof
  which are  Operational Costs and  those elements thereof  which are Investment
  Costs.  Each of  the Managers shall present to the Management Board a proposed
  Program and Budget for the ensuing year on or before October 15.

            10.4 REVIEW AND  APPROVAL OF PROPOSED  PROGRAMS AND BUDGETS.  Within
  fifteen  (15) days  after submission  of a  proposed Program  and Budget,  the
  Management  Board shall meet  to consider the proposed  Program and Budget and
  to vote  on its adoption.    The Management  Board shall vote  separately with
  respect to the  adoption of the  proposed Program  and Budget for  Development
  and  Mining, the proposed Program and Budget  for Processing, and the proposed
  Program and Budget for Exploration.

            10.5 DEADLOCK  ON PROPOSED  PROGRAMS AND  BUDGETS.   If the Members,
  acting through their  representatives on the Management Board, fail to approve
  a Program  and Budget for Development  and Mining (including  any such Program
  and Budget  subject to Subsection 7.6  (a) or (b)),  a Program and  Budget for
  Processing, or  a  Program and  Budget  for  Exploration (including  any  such
  Program and Budget subject to Subsection  7.6 (c), on or before the  beginning
  of the period to which the proposed Program and Budget applies, the  following
  procedures shall be followed:

            (a)  The matter shall be  referred to the Presidents of each  of the
  Members, who shall meet personally,  within ten (10) days after such  referral
  to attempt to reach  agreement concerning the proposed Program and Budget.  If
  the Presidents of  the Members reach agreement  with respect to a  Program and
  Budget, the  Program and Budget  thus agreed to  shall be the Adopted  Program
  and Budget.

            (b)  If the Presidents of the  Members cannot agree with  respect to
  a Program and  Budget within five (5) days after  the meeting held pursuant to
  Subsection  10.5(a), either  Member  may refer  the  matter to  arbitration in
  accordance with Article 18 and 




                                        43








    49





  the Program and Budget determined by arbitration  shall be the Adopted Program
  and Budget.

            10.6 ELECTION  TO PARTICIPATE.  By Notice  to  the Management  Board
  within  twenty  (20) days  after  establishment of  any  Adopted   Program and
  Budget  (other  than the  Mine  Construction  Program  and  Budget, the  Plant
  Construction  Program  and Budget  and  the  initial  Program  and Budget  for
  Exploration  referred to in Subsection 10.1(b))  a Member may elect, by Notice
  to the  Management Board,  to contribute  to the  Investment Costs  of such  a
  Program and Budget or to  a Program and Budget for Exploration in  some lesser
  proportion than  its respective Ownership  Interest, or not  at all,  in which
  cases its Ownership Interest  shall be recalculated as provided in  Article 6.
  If  a Member  fails to  so notify  the Management  Board, the  Member shall be
  deemed to have elected to contribute to such  Program and Budget in proportion
  to  its  respective Ownership  Interest  as  of the  beginning  of  the period
  covered  by the Program and Budget.   No Member shall be  entitled to make the
  election provided for in  this Section with respect  to the Operational  Costs
  of any  Adopted  Program and  Budget  for Development  and  Mining or  of  any
  Adopted Program and Budget for Processing.

            10.7 BUDGET   OVERRUNS;  PROGRAM  CHANGES.     The   Manager  having
  responsibility for an  Adopted Program and  Budget shall,  within twenty  (20)
  days  after the  start of  each  quarter, provide  the  Management Board  with
  quarterly  forecasts  comparing  anticipated  performance  with  the   Adopted
  Program and  Budget and shall  immediately notify the Members  of any material
  departure from  an Adopted Program and  Budget.  If the  total expenses for an
  Adopted  Program and  Budget  (other than  the  Mine Construction  Program and
  Budget or  the Plant  Construction Program and  Budget) exceed  the Budget  by
  more than twenty percent (20%), then the  Manager responsible for such Program
  and Budget shall  be solely  liable for all  such excess  over twenty  percent
  (20%), unless directly caused by  an emergency or unexpected  expenditure made
  pursuant to  Section 10.8  or unless  otherwise authorized  by the  Management
  Board and  such  excess shall  not  be included  in  the calculations  of  the
  Ownership Interests.

            10.8 EMERGENCY OR  UNEXPECTED EXPENDITURES.  In case of emergency, a
  Manager may  take any reasonable  action it  deems necessary to  protect life,
  limb  or property, to protect  the Assets or to comply  with law or government
  regulation.  The  Manager may also make reasonable expenditures for unexpected
  events which are beyond  its reasonable control and which do not result from a
  breach by it of its standard of care.   The Managers shall promptly notify the
  Members of the emergency or unexpected expenditure, and the Managers shall  be
  reimbursed for  all resulting  costs by  the  Members in  proportion to  their
  respective  Ownership  Interests  at  the  time  the emergency  or  unexpected
  expenditures are incurred.

    51

                 (a)  If the  right to take in kind  is interpreted to mean only
  that  a Member  is  authorized  to direct  the  disposition  of its  share  of
  Products by  the  Company,  all  income,  gains,  losses,  deductions  or  tax
  attributes realized  by the Company from any disposition  of Products shall be
  allocated  to  such  Member,  and any  deductions  arising  from  expenditures
  incurred by  such Member  in connection with  such disposition (to  the extent
  they are attributed  to the Company) shall  also be allocated to  such Member.
  If, pursuant  to Section  11.5(b), a  Manager  purchases a  Member's share  of
  Products  for its  own  account, or  sells  such share  of  Products, the  net
  profits  or losses  from such  sale (computed  after taking  into account  the
  reasonable expenses incurred) shall be allocated to the Member.

                 (b)  Exploration  expenses  and  development  cost   deductions
  shall  be allocated  among  the Members  in  accordance with  their respective
  contributions to such expenses and costs.

                 (c)  Subject  to   Section  11.2(l),   depreciation  and   loss
  deductions with respect  to a depreciable  Asset shall be allocated  among the
  Members in  accordance  with their  respective contributions  to the  adjusted
  basis of the Asset which gives rise to the depreciation or loss deduction.

                 (d)  Production  and   operating  cost   deductions  shall   be
  allocated among the Members in accordance with  their respective contributions
  to such costs.

                 (e)  Subject to  Section 11.2(l), cost  depletion and any  loss
  deduction with respect to a depletable property (as  defined in Section 614 of
  the  Code)  shall  be  allocated  to  the Members  in  accordance  with  their
  respective  contributions to the  adjusted basis  of the  depletable property.
  Percentage depletion  under  Section  613  of  the  Code  shall  be  allocated
  (i) first in  the same  manner as  cost depletion  to the extent  it does  not
  exceed  cost  depletion and  (ii) second, to  the extent  percentage depletion
  exceeds  cost  depletion, to  the  Members  in the  same  proportion as  their
  distributive  share  of  gross   income  from  the  depletable   property  (as
  determined under  Section 613(c)  of  the Code)  for the  year in  which  such
  depletion is allowable.

                 (f)  All  deductions and  losses  which  are not  described  in
  Subsections  11.2(a) through  (e),  shall be  allocated  among the  Members in

  such deduction or the adjusted basis of the Asset producing each such loss.

                 (g)  Subject to  Section 11.2(l),  any gain  recognized on  the
  sale  or  other   disposition  of  a  depreciable  Asset  shall  be  allocated
  (i) first, to the extent such gain does not  exceed the amount of depreciation
  claimed  with respect  to  such Asset,  to the  Members  in proportion  to the
  amount of such depreciation previously 


                                        46





    52

  allocated  to,  or  claimed  by,  them; and  (ii) second,  to  the  Members in
  accordance with their Ownership Interests.

                 (h)  Subject to  Section  11.2(l),  any gain recognized on  the
  sale or other disposition of a depletable property (as defined in Section  614
  of the Code)  shall be allocated (i) first,  to the extent such  gain does not
  exceed the  total Recapturable Deductions  (as defined below)  with respect to
  such Property,  to  the  Members  in  proportion  to  the  total  Recapturable
  Deductions  previously allocated to, or claimed by,  them with respect to such
  property  (adjusted for any recapture  of such deductions previously allocated
  to,  or  recognized by,  the  Members),  and (ii) second,  to  the Members  in
  accordance with their Ownership Interests.  As used in the  previous sentence,
  "Recapturable  Deductions" shall  mean  depletion  deductions (to  the  extent
  reflected  in  the  capital  accounts of  the  Members),  exploration  expense
  deductions, and  development expense deductions  attributable to a  depletable
  property,  reduced  (but not  below  zero)  by  any prior  recapture  of  such
  deductions.

                 (i)  Subject to Section  11.2(l), any recapture  of exploration
  expenses  under Section 617(b)(1)(A) of the Code,  and any increase in taxable
  income  realized by  reason  of the  disallowance  of depletion  under Section
  617(b)(1)(B)  of the  Code,  shall be  allocated to  the  Members in  the same
  manner as  the related exploration expenses were  allocated to, or claimed by,
  them.

                 (j)  Subject to Section 11.2(l),  all other items of income and
  gain shall  be allocated  to the  Members in accordance  with their  Ownership
  Interests.

                 (k)  All  tax credits  shall  be allocated  to  the Members  in
  proportion to the  allocation of the item  of income, gain, loss  or deduction
  generated by  the receipt  or  expenditure giving  rise to  the credit.    Any
  credit recapture shall be  allocated to the Members in the  same proportion as
  the related credit was allocated.

                 (l)  Notwithstanding  the  foregoing,  in  the  event  all   or
  substantially all the Assets  or Properties (by value)  are sold or  otherwise
  disposed of, any gain  or loss  recognized by the  Company shall be  allocated
  among the  Members so  that, to  the extent  possible, the Members'  resulting
  Capital  Account  balances  are  in  proportion   to  the  Members'  Ownership
  Interests.    Any  recapture  for  tax  purposes  of  mining  exploration  and
  development  expenditures, depreciation  deductions  and depletion  deductions
  arising by reason of such  a sale or other disposition shall  be allocated, to
  the  extent  consistent  with the  allocation  of  gain  giving rise  to  such
  recapture, to the Member which  was originally allocated, or  which originally
  claimed, the recaptured deduction.





                                        47







    53

                 (m)  Notwithstanding  the  foregoing,  allocations required  by
  Section 704(c)  of the Code  or applicable Treasury  Regulations under Section
  704(b) shall take precedence  over the foregoing allocations, but only  to the
  extent required by the Code or the Treasury Regulations.

                 (n)  Notwithstanding  the  foregoing,  any required  allocation
  under  Section  482  of  the Code  shall  be  accompanied  by  a corresponding
  allocations so  that, to the  extent possible, the  overall allocation to  the
  Members, are consistent with the allocation that would have been made to  each
  of them without regard to any allocation under Section 482 of the Code.

                 (o)  For purposes  of maintaining the  Capital Accounts,  items
  of  income, gain,  loss, depletion  and deduction  shall be  allocated  to the
  extent possible  in  the same  manner  as such  items  are allocated  for  tax
  purposes (as described  above), but taking into account the Capital Accounting
  rules  as specified in  the Treasury  Regulations under Section  704(b) of the
  Code, as reflected in Section 11.12.

            11.3  AGREEMENT NOT TO CAUSE A  TAX TERMINATION.  The  Members agree
  that if any one of them  makes a sale or assignment of its Ownership  Interest
  under this Agreement,  such sale or assignment  shall be structured so  as not
  to cause a termination under  Section 708(b) (1)(B) of the Code.  If a Section
  708(b) (1)(B) termination  is caused, the Member causing the termination shall
  indemnify the other Member  and save  it harmless for  any increase in  taxes,
  interest, and penalties to  the other Member caused by the  termination of the
  tax partnership  created hereunder.   The  indemnification, if  any, shall  be
  computed in a cash flow basis taking into consideration the liability for  tax
  on  any  indemnification proceeds  received  by  the  Member  not causing  the
  termination.  

            11.4 SPECIAL   ALLOCATIONS.     Notwithstanding   the  foregoing,the
  Members  agree that  SFPG,  in recognition  of  its funding  obligations, will
  benefit to the extent of its Capital Account balance under Section 11.12  from
  a special  allocation of all  tax deductions during  the period of -four  (24)
  months beginning with  the month of  first commercial  production.   Likewise,
  Hecla, after a twelve (12) month break  between SFPG's special allocation will
  receive,  in  recognition of  its  contribution  of  the  Hecla Properties,  a
  special  allocation of  tax  deductions for  the  next twenty-four  (24) month
  period,  but only up to the dollar value  of SFPG's special allocation.  After
  the SFPG and  Hecla special allocations, the  Members shall be subject  to the
  allocation provisions of Sections 11.2 or 11.5.

  Management Board  shall determine in  its reasonable judgment  to what extent,
  if any, the Company's  cash on hand exceeds the current and anticipated needs,
  including, without  limitation, needs  for operating  expenses, debt  service,
  acquisitions, reserves,  and mandatory Distributions,  if any.   To the extent
  such excess exists (as  determined by the  Management Board), the Manager  for
  Mining shall  make  Distributions to  the  Members  in accordance  with  their
  Ownership  Interests at  the  time of  the  Distribution.   Such Distributions
  shall be in cash  or property (which need not be  distributed proportionately)
  or partly in both, as determined by the Management Board.  

            (b)    Notwithstanding  Section  11.5(a)  and  except  as  otherwise
  provided in  Article 17.3  (relating to  Distributions in  liquidation of  the
  Company), each  Member shall take  and receive a  distribution in kind of  its
  share (in accordance with its  Ownership Interest) of all refined bullion  and
  other Products  produced from the  dore shipped by the  Manager for Processing
  to a third party  refinery pursuant to Section 5.3.   Any expenditure incurred
  following the Distribution in kind to  a Member of its proportionate share  of
  such Products  shall be  borne by  such Member.   The  Manager for  Processing
  shall give  the Members advance Notice  of the anticipated delivery  date upon
  which  their respective  shares  of such  Products will  be  available.   If a
  Member fails  to take  its share of  such Products  in kind, the  other Member
  shall have the right,  but not the obligation, to purchase  the Member's share
  for its own account or to sell such share as  agent for the Member at not less
  than the  prevailing market price in  the area.  Subject  to the terms  of any
  such contracts of  sale then outstanding, during  any period that a  Member is
  purchasing or selling  the other  Member's share of  such Products, the  Other
  Member may  elect by Notice to the Member to take its Distribution of Products
  in kind.  A Member selling  the other Member's share of Products as agent  for
  the other Member shall  be entitled to deduct from proceeds  of any sale by it
  for the account  of the other Member  all reasonable expenses incurred  in the
  sale.

            11.6 LIMITATION  UPON  DISTRIBUTIONS.    No  Distribution  shall  be
  declared and paid  unless, after the Distribution  is made, the assets  of the
  Company are  in excess of all  liabilities of the Company,  except liabilities
  to Members on account of their contributions.

  Member  from making secured  or unsecured  loans to  the Company  by agreement
  with the Company.

  maintain records  and  accounts of  all  operations  and expenditures  of  the
  Company.   At  a minimum  the  Company shall  keep at  its principal  place of
  business the following records:

                 (e)  Minutes  of  every  annual,  special  meeting  and  court-

  business.  Copies of such  returns, or pertinent information  therefrom, shall
  be  furnished to the  Members within  a reasonable time  after the  end of the
  Company's Taxable Year.

            11.11 TAX  MATTERS PARTNER.   Hecla, so  long as  it is Manager  for
  Mining and is  also a  Member, is hereby  designated the  Tax Matters  Partner

  Member. Each Member's  Capital Account  shall be credited  with the amount  of
  Twenty-Nine  Million  Dollars ($29,000,000)  when  such  Member has  made  the
  contributions required  of  it  by  Section  5.1  and  satisfied  its  funding
  obligations under Section  5.2, regardless of the amounts actually expended by
  such Member  to make  such contributions  or satisfy such  obligations.   Each
  Member's Capital Account  shall generally be  increased by  (1) the amount  of
  money contributed by such Member to the Company for Operations, but  excluding
  amounts contributed  for Operations  conducted to  satisfy the  obligations of
  the Members  pursuant to Section  5.2; (2) the fair  market value  of property
  contributed by  such Member to  the Company, but  excluding contributions made
  to  satisfy the obligations  of the Members pursuant  to Section  5.1, (net of

                 (b)  In  the  event of  a  permitted Transfer  of  an Ownership
  Interest,  the Capital  Account  of the  transferor  shall become  the Capital
  Account of  the  transferee  to  the extent  it  relates  to  the  transferred
  Ownership  Interest  in  accordance  with  Section  1.704-1(b)(2)(iv)  of  the
  Treasury Regulations.

                 (c)  The manner in which Capital Accounts are  to be maintained
  pursuant to this Section 11.12  is intended to comply with the requirements of
  Section 704(b)  of   the  Code  and   the  Treasury  Regulations   promulgated
  thereunder.   If in  the opinion  of the  Company's accountants the  manner in
  which Capital  Accounts  are  to  be  maintained  pursuant  to  the  preceding
  provisions of this Section 11.12  should be modified  in order to comply  with
  Section 704(b)  of  the Code  and  the Treasury  Regulations  thereunder, then
  notwithstanding  anything   to  the  contrary   contained  in  the   preceding
  provisions of this  Section 11.12, the method  in which  Capital Accounts  are
  maintained shall  be so  modified; provided, however,  that any change  in the
  manner of maintaining Capital 



                                        51

  the Members.

  Capital  Account balances  of  the Members,  as  determined after  taking into
  account all Capital  Account adjustments for the Company's Taxable Year during
  which the liquidation  occurs.  The Company  may offset damages for  breach of
  this  Agreement by  a Member  whose interest  is liquidated  (either  upon the
  withdrawal  of the  Member or  the  liquidation of  the  Company) against  the
  amount otherwise distributable to such Member.

  violation of  this Section 13.2, the other  Member may elect by  Notice to the
  reacquiring  Member within forty-five (45) days  after it has actual notice of
  such reacquisition, to  have such properties conveyed to  the Company and made
  subject to  the terms of  this Agreement.   In the  event such an  election is
  made, the reacquired  properties shall  thereafter be  treated as  Properties,
  and  the costs  of reacquisition  shall  be borne  solely  by the  reacquiring
  Member  and shall  not be  included for  purposes of calculating  the Members'
  respective Ownership Interests.

  are traded;

                 (d)  To  the   lenders,   potential  lenders,   credit   rating
  agencies, or insurance providers or brokers of the Company or any Member; or

                 (e)  To  securities, financial  or investment  analysts  of any
  Member, provided  that  before disclosure  of  such  information to  any  such
  analyst  the  disclosing  Member shall  have  provided  to  the non-disclosing
  Member a description or copy of the information to be disclosed.

  As  to  any  disclosure pursuant  to  Subsection  14.2(a)  or (b),  only  such
  confidential information as  such third party shall have a legitimate business
  need to know  shall be disclosed  and such  third party shall  first agree  in
  writing to  protect the  confidential information  from further disclosure  to
  the same extent as the Members are obligated under this Article 14.  

            14.3 DURATION OF  CONFIDENTIALITY.  The  provisions of this  Article
  14 shall  apply  during the  term  of this  Agreement and  for  two (2)  years
  following  termination of  this Agreement pursuant  to Section 6.4, 9.6(c)(ii)
  or  17.1(c), and shall continue  to apply to any  Member who withdraws, who is
  deemed to  have withdrawn, or  who Transfers its  Ownership Interest, for  two
  (2) years following the date of such occurrence.


                                    ARTICLE 15

                                  TRANSFERABILITY

            15.1 GENERAL.  Except  as otherwise specifically provided  herein no
  Member  shall have the right  to Transfer (with  or without consideration) all
  or any part of its Ownership Interest, directly, 


                                        54










    60

  indirectly   or  beneficially.      Each   Member  hereby   acknowledges   the
  reasonableness of  the restrictions on Transfer of Ownership Interests imposed
  by this Agreement  in view of the  Company's purposes and the  relationship of
  the  Members.   Accordingly,  the restrictions  on  Transfer contained  herein
  shall be specifically  enforceable.  In the  event that any Member  pledges or
  otherwise encumbers  any of its  Ownership Interest as  security for repayment
  of a liability, any such pledge  or hypothecation shall be made pursuant  to a
  pledge or hypothecation agreement that  requires the pledgee or  secured party
  to be bound by all the terms and conditions of this Article 15.

            15.2 PREEMPTIVE  RIGHT.   Except as  otherwise  provided in  Section
  15.3, if  a Member  desires  to Transfer  all  or any  part of  its  Ownership
  Interest, the  other Member  shall  have a  preemptive right  to acquire  such
  interests as provided in this Section 15.2

                 (a)  A  Member desiring  to  Transfer all  or  any part  of its
  Ownership Interest shall first offer such  interest to the other Member.   The
  offer shall state  the price and all  other pertinent terms and  conditions of
  the  desired Transfer.  The other Member  shall have thirty (30) days from the
  date such  offer is delivered  to notify  the transferring  Member whether  it
  elects to  acquire the  offered interest  at the  price and on  the terms  and
  conditions set  forth in the offer.   If it does so  elect, the Transfer shall
  be consummated  promptly after  Notice of  such election  is delivered to  the
  transferring Member.

                 (b)  If  the  Member  fails  to  so  elect  within  the  period
  provided for  in  Section 15.2(a),  the  transferring  Member shall  have  one
  hundred twenty (120)  days following the expiration  of such period to  market
  and  consummate a  Transfer at  a price  and on  terms no less  favorable than
  those offered by the  transferring Member  to the other  Member in the  Notice
  required in Section 15.2(a).

                 (c)  If the transferring Member fails  to consummate a Transfer
  within the period  set forth in Section  15.2(b), the preemptive right  of the
  other Member  in such offered  interest shall  be deemed to  be revived.   Any
  subsequent efforts to Transfer such  Ownership Interest shall be  conducted in
  accordance with all of the procedures set forth in this Section 15.2.

            15.3 EXCEPTIONS TO  PREEMPTIVE RIGHT. Section  15.2 shall not  apply
  to the following:

                 (a)  Transfer by a Member of all  or any part of its  Ownership
  Interest to  its Affiliate, provided  that if the  transferee ceases to be  an
  Affiliate  of Hecla  or  SFPG, it  shall be  required  to offer  to  sell such
  Ownership Interest to  the other Member in  accordance with Section 15.2  at a
  price equal to the fair 



                                        55










    61

  market value  of  such Ownership  Interest  as  determined by  an  independent
  appraiser agreed to by the Members;

                 (b)  A   corporate   merger,  consolidation,   amalgamation  or
  reorganization  of  a Member  by  which  the  surviving  entity shall  possess
  substantially all  of the stock, or all of  the property rights and interests,
  and  be subject  to substantially  all of  the liabilities  and obligations of
  that Member; 

                 (c)  A sale  or other commitment or  disposition of Products or
  proceeds from sale  of Products by a  Member upon distribution to  it pursuant
  to Section 11.5; or

                 (d)  Transfer of all or any  portion of the capital stock  of a
  Member, provided that  the Ownership Interest or  Interests of such  Member do
  not constitute more than 80% of the total assets owned by such Member.

            15.4 CONSENT TO TRANSFER.   Notwithstanding any other  provisions of
  this Agreement,  no Member  may Transfer  its Ownership  Interest without  the
  express  written consent of  the other Member,  which consent  may be withheld
  for any  reason, provided, however,  that the provisions  of this Section 15.4
  shall  not  apply  and  any  transferee of  an  interest  in  the  Company  in
  accordance with the terms of this  Agreement shall be admitted to the  Company
  upon execution and delivery to the Manager of a copy of  this Agreement and/or
  any other documents  or instruments requested  by the  Manager to reflect  the
  terms of such  transferee's admission, at any  time when the  requirement that
  the foregoing consent of Members is no longer necessary for the Company to  be
  classified as a partnership for federal income tax purposes.


                                    ARTICLE 16

                   ADDITIONAL MEMBERS, SEPARATE OPERATING AREAS

            16.1 ADDITIONAL MEMBERS. From  the  date  of  the  formation  of the
  Company, any Person acceptable to the Management Board may become a Member  in
  the Company either by  the issuance by the Company of  Ownership Interests for
  such consideration as the Members by their  unanimous vote shall determine, or
  as  a  transferee of  a Member's  Ownership Interest  or any  portion thereof,
  subject to  the terms and conditions of this  Agreement.  No new Members shall
  be  entitled  to any  retroactive  allocation  of  losses,  income or  expense
  deductions incurred by the Company.  The Management Board may, at its  option,
  when  a new  Member  is  admitted, close  the  Company  books (as  though  the
  Company's  tax year had  ended) or make pro  rata allocations  of loss, income
  and  expense deductions to a new Member  for that portion of the Company's tax
  year in which a Member was admitted in accordance with the provisions of 




                                        56










    62

  Section 706(d)  of   the  Code  and   the  Treasury  Regulations   promulgated
  thereunder.

            16.2 SEPARATE OPERATING AREAS.   If at any  time during the  term of
  this Agreement,  the  Management Board  determines  that  it is  advisable  to
  conduct  further  Development or  Mining  within  the  Area  of Interest,  but
  separately from Operations  at the Rosebud  Mine, the  Management Board  shall
  designate which  portion of  the Properties  will comprise  the separate  area
  (the  "Separate  Operating Area"),  and  the Members  shall  enter into  a new
  agreement for  the purpose of  further Exploration, Development  and Mining of
  the  Separate  Operating   Area  ("Separate  Operating  Agreement").   If  the
  Management  Board so determines,  a separate Entity may  be established to own
  and/or operate the  Separate Operating Area.  The Separate Operating Agreement
  shall  provide  that  each  Member's  initial  contribution  to  the  Separate
  Operating  Agreement shall be determined by multiplying its Ownership Interest
  by the fair  market value of the  Separate Operating Area  as determined by  a
  qualified  independent appraiser  acceptable to  both Members.   The  Separate
  Operating Agreement  shall also provide for the  manner in which Products from
  the Separate Operating  Area shall be processed, subject to SFPG's obligations
  with respect to processing as set  forth in Section 5.3.  Following  execution
  of the Separate  Operating Agreement, this Agreement  shall terminate  insofar
  as it  affects the Properties  included in the  Separate Operating Area.   The
  Ownership  Interests of the Members in  the Properties subject to the Separate
  Operating Agreement may differ from the Ownership Interests of the Members  in
  the  remainder  of the  Properties.    If  pursuant  to a  Separate  Operating
  Agreement  the  Ownership Interest  of  a  Member  in  the Properties  subject
  thereto is reduced to fifteen percent (15%),  such Ownership Interest shall be
  deemed  Transferred  to the  other  Member  or its  designee,  subject to  the
  conveyance to the  Member whose  Ownership Interest was  Transferred of a  two
  percent (2%) Net Returns Royalty in such Properties.

                     DISSOLUTION, WINDING UP AND CANCELLATION

            17.1 DISSOLUTION AND WITHDRAWAL.

                 (a)  The Company shall be dissolved only:

                      (i)  by the unanimous written agreement of all Members; 

                      (ii)  as provided in Section 17.1(b); or

                      (iii)  on the  bankruptcy of  any Member  unless the other
  Member consents in  writing to the  continuation of the Company  within ninety
  (90) days after the bankruptcy.

    63

                 (b)  A  Member may  elect  to withdraw  as  a Member  by giving
  Notice to the Company of the effective date of withdrawal,  which shall be the
  later of the end of  the then current Adopted  Program and Budget or at  least
  thirty (30) days  after the  date of the  Notice.  Upon  such withdrawal,  the
  Company  shall dissolve  unless in writing  within ninety (90)  days after the
  withdrawal the  remaining  Member elects  to  continue  the Company,  but  all
  relevant terms of  this Agreement shall  continue and  the withdrawing  Member
  shall be deemed to have transferred to  the Company or a designee of the other
  Member,  without  cost and  free  and  clear  of  royalties,  liens  or  other
  encumbrances arising by, through or under such  withdrawing Member, all of its
  Ownership Interest.   No withdrawal  under this Section  17.1(b) shall relieve
  the withdrawing  Member of its  obligation to make  contributions with respect
  to Operations for  which it  has agreed to  make contributions  and shall  not
  affect its liability under Section 6.5.

                 (c)  Except as provided  in Section 17.1(a), the  Company shall
  not dissolve and shall  continue notwithstanding the expulsion, bankruptcy  of
  any Member  or  the occurrence  of  any event  that terminates  the  continued
  membership of any Member.

            17.2 WINDING UP, LIQUIDATION AND DISTRIBUTION OF ASSETS.

                 (a)  Upon  dissolution, an  accounting  shall  be made  by  the
  Company's  independent accountants of the  accounts of the  Company and of the
  Company's assets,  liabilities  and operations,  from  the  date of  the  last
  previous accounting  until the date of  dissolution.  A Manager  designated by
  the Management Board shall  immediately proceed to wind up the  affairs of the
  Company.

                 (b)  If the  Company is  dissolved and  its affairs  are to  be
  wound up, the designated Manager shall:

                      (i)  Sell  or otherwise  liquidate all  of  the Assets  as
            promptly as practicable  (except to the extent the  Management Board
            may determine to distribute any Assets to the Members in kind),

                      (ii) Allocate  any  gain,  income or  loss  resulting from
            such  sales  to the  Members'  Capital Accounts  in  accordance with
            Article 11,

                      (iii) Discharge  all liabilities of the Company, including
            liabilities to  Members  who  are  also  creditors,  to  the  extent
            otherwise permitted  by law, other  than liabilities to Members  for
            Distributions   and  the  return   of  capital,  and establish  such
            reserves as may  be reasonably  necessary to provide  for contingent
            liabilities of the Company (for purposes of determining 





                                        58











    64

            the Capital  Accounts of the  Members, the amounts  of such reserves
            shall be deemed to be an expense of the Company),

                      (iv) Distribute  the  remaining  Assets  in the  following
            order:

                           (A)  If any  Assets are  to be  distributed in  kind,
                      the net  fair market value of  such Assets as  of the date
                      of  dissolution   shall  be   determined  by   independent
                      appraisal or  by agreement of  the Members.   Such  Assets
                      shall be  deemed  to have  been sold  as  of the  date  of
                      dissolution for their  fair market value, and  the Capital
                      Accounts of the Members shall be adjusted pursuant  to the
                      provisions of Article 11 to reflect such deemed sale.

                           (B)  The  positive balance (if  any) of each Member's
                      Capital Account  (as determined after taking  into account
                      all  Capital Account adjustments for the Company's taxable
                      year  during  which  the  liquidation   occurs)  shall  be
                      distributed to the  Members, either in cash or in kind, as
                      determined  by  the  Management  Board,  with  any  assets
                      distributed  in kind  being  valued  for this  purpose  at
                      their fair market value.   Any  such Distributions to  the
                      Members  in respect  of their  Capital  Accounts shall  be
                      made in  accordance with the  time requirements set  forth
                      in   Section 1.704-1(b)(2)(ii)(b)(2)   of   the   Treasury
                      Regulations.

                 (c)  Upon a  liquidation within the  meaning of Section  1.704-
  1(b)(2)(ii)(g) of  the  Treasury Regulations,  if  any  Member has  a  deficit
  Capital  Account (after  giving effect  to  all contributions,  Distributions,
  allocations  and  other Capital  Account  adjustments for  all  taxable years,
  including the  year during which  such liquidation occurs),  such Member shall
  make,  within  the   time  periods  required  by  the   Treasury  Regulations,
  contributions  to the Company equal  to the negative  balance of such Member's
  Capital Account.

            17.3 NON-COMPETE  COVENANTS.   A  Member  that  is  deemed  to  have
  withdrawn pursuant to  Sections 6.4, 9.6(b)(ii) or 17.1(b), shall not directly
  or indirectly  acquire any interest  in property  within the Area  of Interest
  for twelve  (12)  months  after  the  effective date  of  withdrawal.    If  a
  withdrawing Member, or  an Affiliate of  a withdrawing  Member, breaches  this
  Section,  such Member or  Affiliate shall be obligated  to offer  to convey to
  the non-withdrawing Member,  without cost, any  such property  or interest  so
  acquired.  Such offer shall be made in writing and can be 



                                        59














    65

  accepted by  the non-withdrawing  Member at  any time  within forty-five  (45)
  days after it is received by such non-withdrawing Member.  
            17.4 CERTIFICATE OF CANCELLATION.   When all debts,  liabilities and
  obligations have been  paid and discharged  or adequate  provisions have  been
  made therefor  and  all  of  the  remaining  property  and  assets  have  been
  distributed to the  Members and the Manager responsible therefor has otherwise
  completed the winding up  of the Company, a certificate of  cancellation shall
  be executed  and filed  as  required by  the  Act.   Upon  the filing  of  the
  certificate of cancellation,  the existence of the Company shall cease, except
  for the  purpose  of  suits,  other  proceedings  and  appropriate  action  as
  provided  in the Act.   The  Managers shall  have authority to  distribute any
  Company  property discovered  after dissolution, convey  real estate  and take
  such  other action as  may be necessary  on behalf of and  in the  name of the
  Company.

            17.5 RETURN OF  CONTRIBUTION NONRECOURSE TO  OTHER MEMBERS.   Except
  as  provided  by  Law  or  as  expressly  provided  in  this  Agreement,  upon
  dissolution, each  Member shall look  solely to the  Assets for the return  of
  its  Capital Contribution.    If the  Company's  property remaining  after the
  payment  or  discharge  of  the  debts  and  liabilities  of  the  Company  is
  insufficient to  return the contributions of one or more Members, such Members
  shall have no recourse against any other Member.

  effect, as varied and  supplemented by the provisions of this  Article 18.  If

  fairly implied,  of this Agreement  and the Commercial  Arbitration Rules, the
  terms and conditions of  this Agreement shall apply.  Judgment  may be entered
  on any arbitral award by any court of competent jurisdiction.

  of arbitration, including the arbitrator's fee, administrative and other  fees
  paid  to  the  AAA, witness  fees,  experts  fees,  travel  expenses, and  its
  attorneys' fees.

            (g)  In  determining which  of the  Members'  proposed Programs  and
  Budgets to adopt, the arbitrator  shall determine which proposal  would better
  contribute to  the reasonable, prudent  and efficient Exploration  Development

  consistent with the  purposes of the  Company set forth in  Section 3.1.   The

            19.2 APPLICATION  OF  DELAWARE   LAW.    This  Agreement,   and  the
  application of  interpretation hereof,  shall be  governed exclusively by  its
  terms and by the Laws of the State of Delaware, and specifically the Act.

  waives during  the term of the Company any right that  it may have to maintain
  any action for partition with respect to the Properties.

            19.8 WAIVERS.    The failure  of  any  Member  to  seek redress  for
  violation of  or to  insist upon  the strict  performance of  any covenant  or
  condition of  this Agreement shall  not prevent a subsequent  act, which would
  have originally  constituted  a  violation,  from  having  the  effect  of  an
  original violation.   All waivers of rights  under this Agreement shall  be in
  writing, identified as a  waiver and signed by the  Member who is waiving  the
  rights.

            19.9  RIGHTS  AND REMEDIES  CUMULATIVE.    The rights  and  remedies
  provided by this Agreement  are cumulative and in addition to any other rights
  the parties  may have by Law or otherwise.  The use of any one right or remedy
  by any Member shall not  preclude or waive the  right to use any or all  other
  remedies, provided that multiple recovery of loss or damage shall not occur.

            19.10  SEVERABILITY.   If  any provision  of  this Agreement  or the
  application thereof  to any person  or circumstance shall  be invalid, illegal
  or  unenforceable to  any  extent, the  remainder  of this  Agreement  and the
  application there  of shall not  be affected and  shall be enforceable to  the
  fullest extent permitted by Law.

            19.11 SUCCESSORS  AND  ASSIGNS.   Each  and  all of  the  covenants,
  terms, provisions  and agreements herein  contained shall be  binding upon and
  inure to  the benefit  of the  Members and,  to the  extent permitted  by this
  Agreement, their respective successors and assigns.

            19.12   COUNTERPARTS.     This   Agreement   may  be   executed   in
  counterparts, each  of which  shall be  deemed an  original but  all of  which
  shall constitute one and the same instrument.

            19.13 FORCE MAJEURE.   Except for  the obligation  to make  payments
  when  due hereunder, the  obligations of a Manager  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 Manager to  grant);
  acts of God; Laws, instructions or requests of any government  or governmental
  entity; judgments or orders  of any court;  inability to obtain on  reasonably
  acceptable   terms   any  public   or   private  license,   permit   or  other
  authorization; curtailment or suspension of  activities to remedy or  avoid an
  actual  or alleged,  present  or prospective  violation  of federal,  state or
  local environmental  standards; action  or inaction  by any  federal state  or
  local agency that delays or prevents the issuance  or granting of any approval
  or  authorization  required  to  conduct   Operations  beyond  the  reasonable
  expectations of  the Manager;  acts of  war or  conditions arising  out of  or
  attributable  to war,  whether  declared or  undeclared;  riot, civil  strife,
  insurrection or  rebellion; fire,  explosion, earthquake,  storm, flood,  sink
  holes, drought or other adverse 





                                        64

  weather  condition;  delay   or  failure  by  suppliers   or  transporters  of
  materials,  parts,  supplies,  services or  equipment  or  by  contractors' or
  subcontractors' shortage  of, or inability  to obtain, labor,  transportation,
  materials, machinery, equipment, supplies,  utilities or services;  accidents;
  breakdown  of equipment,  machinery  or facilities;  actions by  native rights
  groups, environmental  groups, or other  similar special  interest groups;  or
  any  other  cause whether  similar  or  dissimilar  to  the foregoing  ("Force
  Majeure").  If  an event of Force  Majeure occurs, the Manager  shall promptly
  give Notice to the Company  of the suspension of performance,  stating therein
  the nature of the  suspension, the reasons therefor, and the expected duration
  thereof. The affected Manager shall  resume performance as soon  as reasonably
  possible.  

            19.14 RULE AGAINST PERPETUITIES.   The Members intend that  the Rule
  Against Perpetuities (and  any similar rule of  law) not be applicable  to any
  provisions of this Agreement.  

            19.15 INVESTMENT REPRESENTATIONS.   The Members understand  (1) that
  the Ownership Interests evidenced by  this Agreement have not  been registered
  under  the   Securities  Act  of  1933  or  any  state  securities  laws  (the
  "Securities Acts")  because the Company  is issuing these Ownership  Interests
  in reliance  upon the  exemptions from  the registration  requirements of  the
  Securities Acts  providing for issuance  of securities not  involving a public
  offering,  (2) that the  Company has relied upon  the fact  that the Ownership
  Interests are  to  be  held  by  each Member  for  investment,  and  (3)  that
  exemption from registrations  under the Securities Acts would not be available
  if  the Ownership  Interests  were  acquired  by  a  Member  with  a  view  to
  distribution.

            Accordingly, each  Member hereby  confirms to  the Company and  each
  other  Member that such Member  is acquiring the  Ownership Interests for such
  own Member's  account, for  investment and not  with a  view to the  resale or
  distribution thereof.  Neither Member shall Transfer  or offer to Transfer any
  of  portion  of  the  Ownership   Interests  unless  there  is   an  effective
  registration  or other  qualification relating  thereto  under the  Securities
  Acts or unless  the holder of Ownership  Interests delivers to the  Company an
  opinion of counsel,  satisfactory to the  Company, that  such registration  or
  other qualification  under the Securities  Acts is not  required in connection
  with  such Transfer or  offer.  Each Member  acknowledges that  the Company is
  under no  obligation to  register the  Ownership Interests  or to assist  such
  Member in complying  with any exemption from registration under the Securities
  Acts if such Member should at a later  date, wish to dispose of the  Ownership
  Interest.  Furthermore,  each Member realizes that the Ownership Interests are
  unlikely  to qualify  for disposition  under Rule  144 of  the Securities  and
  Exchange Commission unless  such Member is not  an "affiliate" of the  Company
  and the  Ownership Interest has been beneficially owned  and fully paid for by
  such Member for at least three (3) years.

    71

            Each Member, prior to acquiring  an Ownership Interest, has  made an
  investigation  of the  Company and  its proposed  business,  and has  had made
  available to each such Member  all information with respect thereto which such
  Member needed to make an informed decision  to acquire the Ownership Interest.
  Each Member  considers itself to  possess experience and  sophistication as an
  investor which  are adequate  for the evaluation  of the  merits and risks  of
  such Member's investment in the Ownership Interest.

            IN WITNESS WHEREOF, the Members  have executed this Agreement  as of
  the year and date first above written.
