Greens Creek and CSX Juneau Mining Inc., an affiliate of CSX ("CSX Juneau"), are the successors in interest to the original parties to the Norbritex Venture. E. Greens Creek, Hecla and CSX, pursuant to authority given to it by its affiliate, desire to integrate operations under the Norbritex Venture with operations under the Venture. Greens Creek 1 8 and CSX are willing to offer the Norbritex Venture and all properties and other assets of the Norbritex Venture to the Venture. F. Greens Creek, Hecla and CSX, the parties to the Amended Venture Agreement, now desire to further amend and to restate the Amended Venture Agreement as the Restated Green's Creek Mining Venture Agreement (the "Restated Agreement"). By this action, Greens Creek, Hecla and CSX do not intend to terminate or reconstitute the existing Venture or to do anything that would otherwise affect its continuity. NOW, THEREFORE, in consideration of the covenants and agreements contained herein, Greens Creek, Hecla and CSX agree that the Amended Venture Agreement is further amended and restated as provided in this Agreement.

After the Effective Date, the Participants, subject to any election permitted by Section 6.3, shall be obligated to contribute funds to adopted Programs in proportion to their respective Participating Interests. ARTICLE VI INTERESTS OF PARTICIPANTS 6.1 Initial Participating Interests. The Participants shall have the following initial Participating Interests: Greens Creek - 57.7505% Hecla - 29.7331% CSX - 12.5164% 6.2 Changes in Participating Interests. A Participant's Participating Interest shall be changed as follows: 11 18 (a) Upon an election by a Participant pursuant to Section 6.3 to contribute less to an adopted Budget than the percentage reflected by its Participating Interest; or (b) In the event of default by a Participant in making its agreed-upon contribution to an adopted Budget, followed by an election by the other Participant to invoke Section 6.4; or (c) As provided in Section 6.5; or (d) Transfer by a Participant of less than all of its Participating Interest in accordance with Article XV; or (e) Acquisition by a Participant of some or all of the Participating Interest of another Participant, however arising. 6.3 Voluntary Reduction in Participation. (a) A Participant may elect in the manner and to the extent provided in Section 9.8, to limit its contributions to an adopted Budget to some lesser amount than its respective Participating Interest. If a Participant elects to contribute to an adopted Budget some lesser amount than its respective Participating Interest, except in the case where the Participant is a Carried Participant, that Participant shall be deemed a "Diluting Participant". The Participating Interest of such Diluting Participant will be reduced effective as of the date the adopted Budget is commenced (the "Diluting Date"). (b) A Diluting Participant's Participating Interest will be provisionally recalculated effective as of the Diluting Date according to the following formula: R = BE(P) + C(P) + N(P) ------------------- BE(A) + C(A) + N(A) R = Revised interest of the Diluting Participant expressed as a percentage. BE(P) = The Equity Account Balance of the Diluting Participant, expressed in dollars, as of the date immediately prior to commencement of the applicable calendar year. BE(A) = The Equity Account Balances of all Participants, expressed in dollars, as of the date immediately prior to the commencement of the applicable calendar year. C(P) = The agreed contribution, if any, of the Diluting Participant toward a Capital Budget or an Exploration Budget. 12 19 C(A) = The aggregate contributions by all Participants called for by a Capital Budget or an Exploration Budget. N(P) = The agreed contribution, if any, of the Diluting Participant toward any Budget other than a Capital Budget or an Exploration Budget, net of the Diluting Participant's allocable share of projected cash distributions under such Budget, computed after giving effect to any dilution relating to a Capital Budget or an Exploration Budget for the same calendar year. N(A) = The aggregate contributions by all Participants called for by any Budget other than a Capital Budget or an Exploration Budget, net of projected cash distributions under such Budget, but in no event less than zero. The Participating Interests of all Non-Diluting Participants shall be increased in proportion to their Relative Interests by the amount by which the Participating Interest of the Diluting Participant is reduced. The recalculations made under this Section 6.3(b) will be provisional and subject to the final adjustments provided for under Section 6.3(c). Examples demonstrating the use of the above dilution formula are included in Exhibit C. (c) As soon as practicable after the end of each calendar year, a final recalculation of each Participant's Participating Interest as of the end of the calendar year shall be made by adjusting the provisional recalculations made under Section 6.3(b) to reflect actual debits, credits and contributions made during that calendar year. A Diluting Participant shall retain all of its rights and all of its obligations (except as provided in Section 6.3(b) above and subject to the provisions of Section 6.5), including the right to participate in future Programs and Budgets at its recalculated Participating Interest. 6.4 Default in Making Contributions. (a) If (i) a Participant defaults in its obligation to pay a contribution or cash call hereunder or, (ii) the Manager is unable to make such reimbursements, reallocations of production, contributions or other adjustments as required under clause (iv) of the second sentence of Section 6.5(b), then any other Participant, by notice to the defaulting Participant, may at any time, but shall not be obligated to, elect to make such contribution or meet such cash call on behalf of the defaulting Participant (a "Cover Payment"). If more than one Participant elects to make the Cover Payment, such Participants, unless they otherwise agree, shall make such Cover Payment in proportion to their Relative Interests, and such Participants shall jointly elect and pursue any remedy provided in this Agreement to recover the Cover Payment. If more 13 20 than one Cover Payment is made for a defaulting Participant, such Cover Payments shall be aggregated, and the rights and remedies described herein pertaining to an individual Cover Payment shall be read to apply to the aggregated Cover Payments. (b) Each Cover Payment shall constitute indebtedness due from the defaulting Participant to the non-defaulting Participant or Participants that make the Cover Payment, which indebtedness shall be payable upon demand and shall bear interest from the date incurred, payable upon demand, or, in the absence of any demand, on the last day of each calendar month, at the rate specified in Section 10.3. (c) Each Participant hereby grants to the other Participants, as security for the repayment of the indebtedness referred to in Section 6.4(b) above or for the repayment of any amount a Carrying Participant is entitled to recover as provided in Section 9.6(b) (together with interest thereon, reasonable attorneys' fees and all other reasonable costs and expenses incurred in collecting payment of such indebtedness or obtaining such recovery and enforcing such security interest), a security interest, mortgage and lien (hereinafter a "security interest"), subordinate only to any security interest granted by Hecla as described below, in and on such Participant's right, title and interest in, whenever acquired or arising, (i) the Assets, (ii) its rights under this Agreement, and (iii) its Participating Interest, together with all Products, proceeds and accessions of the foregoing. Each Participant hereby represents and warrants to each other Participant that such security interest ranks prior to any and all other security interests, except, in the case of Hecla, a security interest in Hecla's interest in Products and proceeds therefrom given under the Bank Credit Agreement dated January 25, 1993, as amended, with Mase Westpac Limited, et al, and any extension or renewal of such security interest granted by Hecla pursuant to any extension or renewal of said bank credit agreement, but not to exceed $50,000,000 and not to extend beyond December 31, 2000. Each Participant hereby agrees to take all action necessary to perfect such security interest, and irrevocably appoints each other Participant as its attorney-in- fact to execute, file and record all financing statements and any other documents necessary to perfect or maintain such security interest or otherwise give effect to the provisions hereof. Each Participant hereby agrees that it shall not execute, foreclose or otherwise take action to enforce such security interest except upon 30 days' prior notice to the defaulting Participant, provided that the foregoing shall not prohibit the taking of any action to make, prove or protect a claim in any bankruptcy or insolvency proceeding of the defaulting Participant. Upon completion of execution, foreclosure or other action to enforce the security interest described herein, the defaulting Participant shall be deemed to have withdrawn from this Agreement and shall relinquish its entire Participating Interest. In the event the defaulting Participant is subjected to execution or foreclosure proceedings pursuant to the terms of this Section, 14 21 to the extent allowed by applicable law the defaulting Participant waives any available right of redemption from and after the date of judgment, any required valuation or appraisal of the mortgaged or secured property prior to sale, any available right to stay execution or to require a marshalling of assets and any required bond in the event a receiver is appointed. In addition, to the extent permitted by applicable law, each Participant grants to each other Participant a power of sale as to any property that is subject to the security interest granted hereunder, such power to be exercised in the manner provided by applicable law or otherwise in a commercially reasonable manner and upon reasonable notice. (d) If a Cover Payment shall have been made, upon the giving of not less than 15 days' prior notice to the defaulting Participant, the non-defaulting Participants that made the Cover Payment may, but shall not be obligated to, elect to effect an adjustment of the defaulting Participant's Participating Interest pursuant to this Section 6.4(d); provided, however, that if within such 15 day period the defaulting Participant shall provide evidence to the reasonable satisfaction of the non- defaulting Participants that made the Cover Payment that it will have the funds to, and will, within 10 days of the expiration of such 15 day period, pay all indebtedness owing by the defaulting Participant to such non-defaulting Participants, then such adjustment of the Participating Interest may not be effected until the end of such additional 10 day period. Upon such election, or, if applicable, at the end of such additional 10 day period, an amount equal to 125% times the Cover Payment made by each non-defaulting Participant shall be deducted from the defaulting Participant's Equity Account Balance and added to the Equity Account Balance of the non-defaulting Participants that made the Cover Payment, and the Participating Interests of the Participants shall be recalculated based on the adjusted Equity Accounts. (e) If a Cover Payment shall have been made and the indebtedness arising therefrom shall not have been discharged, upon not less than 30 days' notice to the defaulting Participant, the non-defaulting Participants that made the Cover Payment may, but shall not be obligated to, elect to purchase the whole of the Participating Interest of the defaulting Participant, at a purchase price equal to the fair market value of such Participating Interest as determined by an independent appraiser appointed by such non-defaulting Participants (or, if the defaulting Participant objects to the person so appointed, within 10 days of receiving notice thereof, then by an independent appraiser appointed by joint action of independent appraisers appointed by each of the non-defaulting and defaulting Participants; provided, however, that if the defaulting Participant fails to designate an independent appraiser for such purpose within 10 days of such objection, then the person originally designated by such non-defaulting Participants shall serve as the independent appraiser). There shall be withheld from the purchase price payable upon transfer of such Participating Interest the amount of indebtedness of the 15 22 defaulting Participant owing to the non-defaulting Participants that made the Cover Payment, together with unpaid interest accrued thereon to the date of such transfer. Upon payment of such purchase price, the defaulting Participant shall be deemed to have withdrawn from this Agreement and shall relinquish its entire Participating Interest. Such relinquished Participating Interest shall be deemed to have been assigned automatically to the non-defaulting Participants that made the Cover Payment in proportion to their Relative Interests. (f) In lieu of the remedy provided in Section 6.4(e) above, if a Cover Payment shall have been made and the indebtedness therefrom shall not have been discharged, upon not less than 30 days' notice to the defaulting Participant, the non- defaulting Participants that made such Cover Payment may, but shall not be obligated to, deem the defaulting Participant to have automatically relinquished to such non-defaulting Participants that portion of its Participating Interest as is necessary to reduce such interest to less than 5%, such that the defaulting Participant becomes subject to Section 6.5. Such relinquished Participating Interest shall be deemed to have been assigned automatically to the non-defaulting Participants that made the Cover Payment in proportion to their Relative Interests. (g) Upon a default of the type referred to in Section 6.4(a) above, the right of the defaulting Participant to take delivery in kind under Article XI shall cease. Subject to prior existing liens or security interests, the non-defaulting Participants that made the Cover Payment may sell the defaulting Participant's share of Products in any commercially reasonable manner. If the non-defaulting Participants that made the Cover Payment elect to sell the defaulting Participant's share of Products, they shall apply the proceeds thereof first, to make any contribution or meet any cash call not made or met by the defaulting Participant or made or met on its behalf, and second, to pay the indebtedness and unpaid and accrued interest thereon then owing by the defaulting Participant to such non-defaulting Participants. If the proceeds are not adequate to meet any cash call and to pay any indebtedness and interest thereon, the non- defaulting Participants that made the Cover Payment may proceed to exercise all other rights available to such Participants pursuant to the procedures set out in this Section 6.4. The right of a defaulting Participant to take in kind its share of Products shall be reinstated at the first time when such Participant is not in default in its obligation to make a contribution or meet a cash call and all indebtedness and interest thereon arising out of the making by the non-defaulting Participants of Cover Payments has been paid in full. (h) A defaulting Participant may cure such default by paying all indebtedness and interest thereon then owing to the non-defaulting Participants that made the Cover Payment, and all costs and expenses, including reasonable attorneys' fees, incurred 16 23 by such non-defaulting Participants in the exercise of their rights hereunder, at any time prior to (i) consummation of an action to execute or foreclose on a security interest granted pursuant to Section 6.4(c), (ii) an adjustment of Participating Interests being effected pursuant to Section 6.4(d), (iii) consummation of a purchase of its Participating Interest pursuant to Section 6.4(e), or (iv) relinquishment of a portion of its Participating Interest pursuant to Section 6.4(f). (i) The Participants acknowledge that if a Participant defaults in making a contribution or cash call or in repaying the indebtedness resulting from a Cover Payment as required in this Agreement, the damages resulting from such default will be uncertain and difficult to measure. The Participants agree that rights and remedies provided to the nondefaulting Participants in this Agreement constitute reasonable liquidated damages. 6.5 Elimination of Minority Interest. (a) Upon the reduction of its Participating Interest to less than 5%, except where such reduction results from the operation of the provisions of Section 6.4(c), (d) or (e), a Participant shall be deemed to have withdrawn from this Agreement and shall relinquish its entire Participating Interest. Such relinquished Participating Interest shall be deemed to have been assigned automatically to the other Participants in proportion to their Relative Interests, subject to a right of the withdrawing Participant to receive 5% of Net Proceeds, if any, calculated as provided in Exhibit D, and not from any other source, up to an aggregate amount equal to the withdrawing Participant's Equity Account Balance as of the date of such withdrawal. In the event that any of Greens Creek, Hecla or CSX shall, as a result of one or more transfers, have more than one successor, each such Participant and its successors in the aggregate shall not be entitled to a Net Proceeds interest in excess of 5%. (b) For purposes of this Section 6.5, the determination of whether a Participant's Participating Interest has been reduced to less than 5% under the provisions of Section 6.3 shall be made on the basis of the provisionally recalculated Participating Interest provided for under Section 6.3(b), and the relinquishment, withdrawal and entitlements provided for in this Section 6.5 shall be effective as of the Diluting Date. However, if the final adjustment provided for under Section 6.3(c) results in a recalculated Participating Interest of 5% or more: (i) the Diluting Participant's recalculated Participating Interest shall be deemed, effective as of the last day of the Budgetary Period, to have automatically revested; (ii) such Participant shall be reinstated as a Participant, with all of the rights and obligations pertaining thereto; (iii) the Net Proceeds interests (if any) vested under the terms of Section 6.5(a) shall terminate; and (iv) the Manager, on behalf of the Participants, shall make such reimbursements, reallocations of production, contributions and 17 24 other adjustments as are necessary so that, to the extent possible, each Participant will be placed in the position it would have been in had the adjusted recalculated Participating Interests been in effect throughout the Budgetary Period. Similarly, if such final adjustment results in a recalculated Participating Interest for any Participant of less than 5% for a Budgetary Period as to which the provisional calculation had not resulted in a Participating Interest of less than 5%, then such Participant, at its election within 30 days of notice of the final adjustment, may contribute an amount which would result in a revised final adjustment of 5%, or, if no such election is made, such Participant shall be deemed to have withdrawn under the terms of Section 6.5(a) as of the end of such Budgetary Period. If the Participants are required to make contributions or other adjustments pursuant to this Section 6.5(b), the Manager shall have the right to sell a Participant's share of Products and to apply the proceeds of such sale to satisfy that Participant's obligation to make such contributions or adjustments. 6.6 Continuing Liabilities Upon Adjustments of Participating Interests. Any reduction of a Participant's Participating Interest under this Article VI shall not relieve such Participant of its share of any liability (including, without limitation, its share of any reclamation liability), arising out of Operations conducted prior to such reduction, whether such liability is known or unknown at the time of such reduction and whether such liability is asserted before or after such reduction. For purposes of this Article VI, such Participant's share of such liability shall be equal to its Participating Interest at the time such liability was incurred. The increased Participating Interest accruing to a Participant as a result of the reduction of any other Participant's Participating Interest shall be free of royalties, liens or other encumbrances arising by, through or under such other Participant, other than those existing at the time the Properties were acquired or those to which the Participants have given their written consent. An adjustment to a Participating Interest need not be evidenced during the term of this Agreement by the execution and recording of appropriate instruments, but each Participant's Participating Interest shall be shown in the books of the Manager. However, any Participant, at any time upon the request of any other Participant, shall execute and acknowledge instruments necessary to evidence such adjustment in form sufficient for recording in the jurisdiction where the Properties are located. ARTICLE VII MANAGEMENT COMMITTEE 7.1 Organization and Composition. The Participants hereby establish a Management Committee to determine overall policies, objectives, procedures, methods and actions under this Agreement, and to adopt Programs and Budgets as provided in Article IX. The Management Committee shall consist of one member appointed by each Participant. Each Participant may appoint one or more alternates 18 25 to act in the absence of its regular member. Any alternate so acting shall be deemed a member. Appointments shall be made or changed by notice to the other Participants. 7.2 Decisions. Each Participant, acting through its appointed member, shall have one vote on the Management Committee. Unless otherwise provided in this Agreement, the vote of the Participant or Participants with a Participating Interest over 50% shall determine the decisions of the Management Committee. 7.3 Meetings. (a) The Management Committee shall hold regular quarterly meetings in each of the first three calendar quarters and an annual meeting on or before December 10th of each year. The meetings will be held in Juneau, Alaska, or at other mutually agreed places. The Manager shall give 30 days' notice to the Participants of such regular meetings. Additionally, any Participant may call a special meeting upon 10 days' notice to the Manager and the other Participants. In case of emergency, reasonable notice of a special meeting shall suffice. A quorum of the Management Committee shall be necessary to conduct Management Committee business. There shall be a quorum if at least one member representing each Participant is present. Each notice of a meeting shall include an itemized agenda prepared by the Manager in the case of a regular meeting, or by the Participant calling the meeting in the case of a special meeting, but any matters may be considered with the consent of all Participants. The Manager shall prepare minutes of all meetings and shall distribute copies of such minutes to the Participants within 20 days after the meeting. The minutes, when signed by all Participants, shall be the official record of the decisions made by the Management Committee and shall be binding on the Manager and the Participants. If personnel employed in Operations are required to attend a Management Committee meeting, reasonable costs incurred in connection with such attendance shall be a Venture cost. All other costs shall be paid for by the Participants individually. (b) If a Participant fails to attend a regular or special meeting for which notice has been given as described above, the Manager or the Participant calling the meeting, as applicable, may give a second notice of the meeting in compliance with the above rules for special meetings. If the non-attending Participant does not attend the meeting scheduled by the second notice, there shall be a quorum if at least one member of each other Participant is present. 7.4 Action Without Meeting. In lieu of meetings, upon unanimous agreement of the Participants, the Management Committee may hold conferences by telephone or other means of electronic communication, so long as all decisions are immediately confirmed in writing by the Participants. 19 26 7.5 Matters Requiring Approval. Except as otherwise delegated to the Manager in Section 8.2, the Management Committee shall have exclusive authority to determine all management matters related to this Agreement. ARTICLE VIII MANAGER 8.1 Appointment. The Participants hereby appoint Greens Creek as the Manager with overall management responsibility for Operations. Greens Creek hereby agrees to serve until it resigns as provided in Section 8.4. 8.2 Powers and Duties of Manager. Subject to the general oversight and direction of the Management Committee as described in Section 7.1, the Manager is vested with full authority to carry out the day-to-day management of the Venture and to conduct all Operations. The Manager agrees, by itself, or through its employees, agents or contractors, to carry out its duties in accordance with the terms and intent of this Agreement, on behalf of and for the account of the Participants according to their Participating Interests.

(d) The Manager shall conduct such title examinations and cure such title defects as may be advisable in the reasonable judgment of the Manager. (e) The Manager shall: (i) make or arrange for all payments required by leases, licenses, permits, contracts and other 20 27 agreements related to the Assets; (ii) pay all taxes, assessments and like charges on Operations and Assets except taxes determined or measured by a Participant's sales revenue or net income. If authorized by the Management Committee, the Manager shall have the right to contest in the courts or otherwise, the validity or amount of any taxes, assessments or charges if the Manager deems them to be unlawful, unjust, unequal or excessive, or to undertake such other steps or proceedings as the Manager may deem reasonably necessary to secure a cancellation, reduction, readjustment or equalization thereof before the Manager shall be required to pay them, but in no event shall the Manager permit or allow title to the Assets to be lost as the result of the nonpayment of any taxes, assessments or like charges; and (iii) shall do all other acts reasonably necessary to maintain the Assets.

The non-managing Participants shall have the right to participate, at their own expense, in such litigation or administrative proceedings. The non-managing Participants shall approve in advance any settlement involving payments, commitments or obligations in excess of $250,000 in cash or value. The failure by a Participant to vote on any settlement proposed by the Manager shall be deemed to be a vote to approve the proposed settlement. (h) The Manager shall provide insurance for the benefit of the Participants as provided in Exhibit E. (i) The Manager may dispose of Assets, whether by abandonment, surrender or Transfer in the ordinary course of business, except that Properties may be abandoned or surrendered only as provided in Article XIV.

(k) The Manager shall perform or cause to be performed during the term of this Agreement all assessment and other work or make any payments in lieu thereof required by law in order to maintain the unpatented mining claims included within the Properties. The Manager shall have the right to perform the assessment work required hereunder pursuant to a common plan of exploration, and continued actual occupancy of such claims and sites shall not be required. The Manager shall not be liable on account of any determination by any court or governmental agency that the work performed or payment made by the Manager does not constitute the required annual assessment work or occupancy or payments for the purposes of preserving or maintaining ownership of the claims, provided that the work is done or the payments are made in accordance with the adopted Program and Budget. The Manager shall timely record with the appropriate county and file with the appropriate United States agency, affidavits in proper form attesting to the performance of assessment work or notices of intent to hold in proper form, and allocating therein, to or for the benefit of each claim, at least the minimum amount required by law to maintain such claim or site.

(n) The Manager shall keep the Management Committee advised of all Operations by submitting in writing to the Management Committee: (i) monthly progress reports which include statements of expenditures and comparisons of such expenditures to 22 29 the adopted Budget; (ii) periodic summaries of data acquired; (iii) copies of reports concerning Operations; (iv) a detailed final report within 60 days after completion of each Program and Budget, which shall include comparisons between actual and budgeted expenditures and comparisons between the objectives and results of Programs; and (v) such other reports as the Management Committee may reasonably request. At all reasonable times the Manager shall provide the Management Committee or the representative of any Participant, upon the request of any member of the Management Committee, access to, and the right to inspect and copy all maps, drill logs, core tests, reports, surveys, assays, analyses, production reports, operations, technical, accounting and financial records, and other information acquired in Operations. Such material and information shall be solely for the benefit of the Participants to whom such material and information are made available and the Participants agree not to discuss or disclose the same to any third parties except as provided in this Agreement. The non-managing Participants further agree that their use of or reliance on such material and information shall be at their sole risk and further agree to indemnify, defend and hold harmless the Manager and its Affiliates, and its or their respective directors, officers, shareholders, employees, agents and attorneys, from and against any Liabilities which may be imposed upon, asserted against or incurred by any of them and which arise out of or result from use of or reliance on such material and information by the non- managing Participant, or any third party to whom the non-managing Participant discloses such material and information. Subject to the Manager's standard of care under Section 8.3, the Manager makes no representation or warranty as to the completeness or accuracy of any material or information disclosed hereunder. (o) The Manager shall allow the non-managing Participants, at the latter's sole risk and expense, and subject to reasonable safety regulations, to inspect the Assets and Operations at all reasonable times, so long as the inspecting Participant does not unreasonably interfere with Operations. (p) The Manager shall prepare and present Programs and Budgets as provided in Article IX. (q) The Manager shall undertake all other activities reasonably necessary to fulfill the foregoing. If the Manager's failure to perform any duty under this Section 8.2 results from the failure of a non-managing Participant to perform acts or to contribute amounts required of it by this Agreement the Manager shall not be in default of any duty owed to such non-managing Participant. 8.3 Standard of Care. The Manager shall conduct all Operations in a good, workmanlike and efficient manner, in accordance with sound mining and other applicable industry standards and practices, and in accordance with the terms and 23 30 provisions of leases, licenses, permits, contracts and other agreements pertaining to Assets. The Manager shall not be liable to the non-managing Participants for any act or omission resulting in damage or loss except to the extent caused by or attributable to the Manager's willful misconduct or gross negligence. 8.4 Resignation; Deemed Offer to Resign. The Manager may resign upon two months' prior notice to the other Participants. If the Manager resigns or is deemed to have resigned and such deemed offer is accepted as provided in this Section, then the other Participants shall elect a new Manager at least 15 days prior to the effective date of the Manager's resignation. If any of the following shall occur, the Manager shall be deemed to have offered to resign, which offer shall be accepted by the other Participants, if at all, within 90 days following the date of the event constituting such deemed offer: (a) The Participating Interest of the Manager becomes less than any other Participant; or (b) The Manager fails to perform a material duty or obligation imposed upon it under this Agreement and such failure continues for a period of 60 days after notice from the other Participants demanding performance; or (c) The Manager fails to pay or contest in good faith its bills within 60 days after they are due; or (d) A receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official for a substantial part of its assets is appointed and such appointment is neither made ineffective nor discharged within 60 days after the making thereof, or such appointment is consented to, requested by, or acquiesced in by the Manager; or (e) The Manager commences a voluntary case under any applicable bankruptcy, insolvency or similar law now or hereafter in effect; or consents to the entry of an order for relief in an involuntary case under any such law or to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or other similar official of any substantial part of its assets; or makes a general assignment for the benefit of creditors; or fails generally to pay its or Venture debts as such debts become due; or takes corporate or other action in furtherance of any of the foregoing; or (f) Entry is made against the Manager of a judgment, decree or order for relief affecting a substantial part of its assets by a court of competent jurisdiction in an involuntary case commenced under any applicable bankruptcy, insolvency or other similar law of any jurisdiction now or hereafter in effect. 24 31 8.5 Payments to Manager. The Manager shall be compensated for its services and reimbursed for its costs hereunder in accordance with the Accounting Procedure. 8.6 Transactions with Affiliates. If the Manager engages Affiliates to provide services hereunder, it shall do so on terms no less favorable than would be the case with unrelated persons in arm's-length transactions. 25 32 ARTICLE IX PROGRAMS AND BUDGETS 9.1 Operations Pursuant to Programs and Budgets. Except as otherwise provided in Section 9.11 and Article XIII, Operations shall be conducted, expenses shall be incurred, and Assets shall be acquired only pursuant to Programs and Budgets adopted by the Management Committee. 9.2 Contents of Programs and Budgets. The Program and Budget shall consist of the following components (each a "Component") together with such other information determined to be relevant by the Manager or required by the Management Committee: (a) The Program; (b) A forecast of projected Revenues for the Budgetary Period; (c) An Operating Budget covering Operating Expenses and Sustaining Capital expenditures for the Budgetary Period; (d) Projected Available Cash from Operations for the Budgetary Period; (e) If appropriate, a Budget for Exploration within the Area of Interest for the Budgetary Period; (f) If appropriate, a Capital Budget for the Budgetary Period; and (g) If appropriate, a Program and Budget for each Separate Capital Project approved pursuant to Section 9.7. 9.3 Presentation of Programs and Budgets. Proposed Programs and Budgets shall be prepared by the Manager for a period of one year or, in the case of Capital Budgets, any longer period. Individual Components of the Budget will not necessarily have the same Budgetary Period. Each adopted Program and Budget, regardless of length of time encompassed by the Program and Budget, shall be reviewed at least once a year at the annual meeting of the Management Committee. At least one month prior to the annual meeting of the Management Committee, a proposed Program and Budget for the succeeding period shall be prepared by the Manager and submitted to the Participants. 9.4 Review of and Vote on Proposed Programs and Budgets. (a) Within 15 days after submission of a proposed Program and Budget, each Participant shall submit to the Manager its comments on the proposed Program and Budget. The Manager shall then consider the comments and may, but shall not be obligated to, 26 33 revise the Program and Budget to take into account any such comments. Within 10 days of receipt of any comments or 10 days after the close of the 15 day period if no comments are received, the Manager shall submit the final proposed Program and Budget to the Participants. At the annual meeting of the Management Committee, each Participant shall vote to adopt or reject each Component of the proposed Program and Budget identified in Sections 9.2(c), (e) and (f). (b) If a Participant fails to vote on any or all of the Components of the proposed Program and Budget, the failure shall be deemed to be a vote by the Participant to reject each Component of the proposed Program and Budget identified in Sections 9.2(c), (e) and (f) that the Participant has not voted to adopt, except that a failure to vote on an Operating Budget that requires unanimous approval pursuant to Section 9.5(a), an Exploration Budget that requires unanimous approval pursuant to Section 9.5(c), or a Budget overrun that requires a unanimous vote of the Participants funding the affected Component of a Budget as provided in Section 9.10, shall be deemed to be a vote to adopt the component of the Budget or to approve the overrun. 9.5 Votes Required for Approval. The Program and Budget may be adopted in whole or in part as follows: (a) Operating Budgets. If Available Cash from Operations as projected in the Budget is positive or is no more than $7.0 million negative for any one year period, a favorable vote of the Participant or Participants representing a majority of the Participating Interests shall be required to adopt the Operating Budget. If Available Cash from Operations as projected in the Budget is more than $7.0 million negative for any one year period, a favorable vote of two Participants holding a majority of the Participating Interests shall be required to adopt the Operating Budget. For purposes of this requirement, Participants that are Affiliates shall be deemed to be a single Participant. For the second or any subsequent consecutive year for which Available Cash from Operations is projected in the Budget to be more than $7.0 million negative for any one year period, a favorable unanimous vote of all Participants shall be required to adopt the Operating Budget. (b) Capital Budgets. Capital Budgets may be proposed for a single year or multiple years. In each year for which a vote on a Capital Budget is required, all proposed expenditures for Capital for that year and the amount of a multiple year Capital Budget budgeted to be spent in that year, except for amounts in a budget to be spent in Capital Budgets for those projects identified in Section 9.7 below, will be aggregated in a single Capital Budget for purposes of determining the vote required to adopt the proposed single year Capital Budget for that year. 27 34 (i) For any single year in which the aggregate of all Capital Budgets is $10 million or less, a favorable vote of the Participant or Participants representing a majority of the Participating Interests shall be required to adopt a Capital Budget; (ii) For any single year in which the aggregate of all Capital Budgets is more than $10 million, a unanimous favorable vote of all Participants shall be required to adopt a Capital Budget; (iii) For any multiple year Capital Budget that is $10 million or less in any single year and is $25 million or less in the aggregate, a favorable vote of the Participant or Participants representing a majority of the Participating Interests shall be required to adopt the Capital Budget; and (iv) For any multiple year Capital Budget of more than $10 million in any single year or more than $25 million in the aggregate, a unanimous favorable vote of all Participants shall be required to adopt the multiple year Capital Budget. (c) Exploration Budgets. Exploration Budgets for Exploration within the Area of Interest of $1.5 million or less shall be adopted by the favorable vote of the Participant or Participants representing a majority of the Participating Interests. Exploration Budgets for Exploration within the Area of Interest of more than $1.5 million require a unanimous favorable vote of all Participants for adoption. (d) Indexing of Budgetary Limits. The budgetary limits set out in Sections 9.5(a), (b) and (c) shall be indexed upwards or downwards by multiplying each amount by a fraction, the numerator of which is the latest available Producers Price - All Commodities Index and the denominator of which is the most recently available Producers Price - All Commodities Index as of March 1, 1994. 9.6 Reconsideration of Capital Budgets. If the Management Committee fails to adopt a Capital Budget, the Manager may call for reconsideration of the Capital Budget. (a) By calling for reconsideration, the Manager (and any Participant electing to become a Carrying Participant) shall become a Carrying Participant and shall be a obligated to fund the share of the Capital Budget of each Participant that failed to vote favorably for the Capital Budget, who shall become a Carried Participant, and each Carried Participant shall be deemed to have voted favorably for the Capital Budget. (b) If a Participant becomes a Carrying Participant for a Carried Participant as provided in Section 9.6(a), following completion of the project for which the Capital Budget was adopted, the Carrying Participant shall be entitled to recover out of 70% of 28 35 the Carried Participant's share of Available Cash from Operations, as reduced by the Carried Participant's obligation to fund other Capital Budgets or Exploration Budgets in which it has elected to participate, any amount funded pursuant to the Capital Budget on behalf of the Carried Participant, together with interest at the Prime Rate plus 2%. The Carrying Participant shall have the same rights with respect to the Carried Participant's interest in the Venture and the Assets as are afforded a Lienholder in a Project Financing undertaken pursuant to Section 16.2 and the lien, security interest and mortgage provided in Section 6.4(c). An example showing the manner in which the Carrying Participant recovers the amount funded is set forth in Exhibit J. 9.7 Separate Capital Projects. In addition to the items that might be included in a Capital Budget proposed pursuant to Section 9.5(b), Separate Capital Projects have been identified by the Manager that may be proposed by the Manager. These projects will have separate Programs and Budgets which will be prepared, presented and reviewed as provided in Sections 9.2 and 9.3 but which will not be subject to the voting procedures and requirements set forth in Sections 9.4, 9.5 and 9.6. All other relevant provisions of this Agreement shall apply to such Programs and Budgets. (a) The Management Committee shall be deemed to have adopted the Programs and Budgets for the Southwest Extension Ore Development Project and the West Ore Zone Development Project, whether proposed individually or as a single project, if the Manager completes a feasibility study and recommends approval of the project or projects. Each Participant shall have the same right to elect to participate or not in these Budgets as is provided for other Capital Budgets in Section 9.8. (b) The Management Committee shall be deemed to have adopted the Program and Budget for the Mine and Mill Expansion Project if the Manager completes a feasibility study and recommends approval of the project. Each Participant will have the same right to elect to participate or not in this Budget as is provided for other Capital Budgets in Section 9.8. In the alternative, each Participant shall have the right, at its option, to fund its share of the Budget for the Mine and Mill Expansion Project through Project Financing arranged by the Manager to the extent the Participant's share of these Budgets exceeds its projected share of Available Cash from Operations as reduced by its projected obligations to fund Exploration Budgets and other Capital Budgets. If Project Financing is not available at reasonable terms in the opinion of the Manager, the Manager shall be obligated to fund, at the election of each other Participant, such other Participant's share of the budget for the project to the extent its share of the budget exceeds its projected share of Available Cash from Operations as reduced by its projected share of Exploration Budgets or other Capital Budgets. In such case, the Manager shall become a Carrying Participant and each nonfunding Participant shall become 29 36 a Carried Participant on the same terms as described in Section 9.6(b) above, except that the Carrying Participant shall be entitled to recover the amounts funded before completion of the Mine and Mill Expansion Project. 9.8 Election to Participate. At the time of the final vote adopting or rejecting a Program and Budget pursuant to Section 9.4, where permitted as provided below, each Participant shall advise the Management Committee whether it desires to contribute to a Component of a Budget in some lesser amount than its respective Participating Interest, or not at all. If a Participant fails to so notify the Management Committee, the Participant shall be deemed to have elected not to contribute to any Component of the Budget for which it may so elect in proportion to its respective Participating Interest as of the beginning of the period covered by the Program and Budget. If a Participant notifies or is deemed to have notified the Management Committee that it does not intend to contribute all or part of its share to a Budget, the following provisions shall apply: (a) If the Component of the Budget is an Operating Budget and Available Cash from Operations as projected in the Budget is positive or is no more than $7.0 million negative in a calendar year, or if the Budget is a Shutdown Budget, a Participant will have no right to elect to contribute less than its full share of the Operating Budget and will be in default as provided in Section 10.3 for a failure to meet a cash call issued pursuant to such Operating Budget or Shutdown Budget, and the provisions of Section 6.4 will apply. (b) If the Component of the Budget is an Operating Budget and the Available Cash from Operations as projected in the Budget is more than $7.0 million negative in a calendar year, a Participant may elect to contribute less than its share, or not at all, to the Operating Budget to the extent such Available Cash from Operations is more than $7.0 million negative in a calendar year, and its Participating Interest shall be recalculated as provided in Section 6.3. (c) If the Component of the Budget is an Exploration Budget, a Participant may elect to contribute less than its share, or not at all, and its Participating Interest shall be recalculated as provided in Section 6.3. (d) If the Component of the Budget is a Capital Budget, a Participant may elect to contribute less than its share, or not at all, and its Participating Interest shall be recalculated as provided in Section 6.3. In addition, a Participant will have the right to change its election in each year of a multiple year Capital Budget, except for a Capital Budget adopted pursuant to Section 9.7, at the time the Capital Budget is reviewed pursuant to Section 9.3; provided, however, that if a Participant that has previously elected to participate in a multiple year Capital Budget 30 37 subsequently elects to reduce its participation and no other Participant agrees to fund the amount of the reduction, the Manager will limit to the extent practicable or terminate the project contemplated by the Capital Budget and, if a project is terminated, the Participants that initially agreed to fund the Capital Budget will share proportionately the costs of termination. (e) Notwithstanding a Participant's right to contribute less than its full share of a Component of the Budget, or not at all, as provided in Sections 9.8(b), 9.8(c) and 9.8(d) above, if no other Participant agrees to fund the amount of the Component of the Budget that another Participant is unwilling to contribute, the Component of the Budget will be deemed not to have been adopted and the other provisions of this Article IX will apply. 9.9 Deadlock on Proposed Programs and Budgets. If the Participants, acting through the Management Committee, fail to adopt an Exploration Budget or a Capital Budget by the beginning of the period to which the proposed Budget applies or fail to approve an overrun of an Exploration Budget or Capital Budget as provided in Section 9.10, the Manager shall make no expenditures or additional expenditures, as appropriate, with respect to those Components of the Budget. If the Participants fail to adopt an Operating Budget by the beginning of the period to which the proposed Budget applies or fail to approve an overrun of an Operating Budget as provided in Section 9.10, the Manager shall curtail operations and reduce all activities of the Venture, whether funded by an Operating Budget or some other Budget, except for those provided for in Section 9.7, to the level required to protect the Assets, to maintain the operating permits of the Venture, and to generally provide for safety, environmental compliance and compliance with other legal and contractual obligations of the Venture. The costs of such activities shall be shared by the Participants in proportion to their Participating Interests and will be included in a Shutdown Budget, as may be amended from time to time. As soon as practicable following the failure to adopt an Operating Budget or to approve an overrun of an Operating Budget, the Manager will prepare and circulate a Shutdown Budget. A Shutdown Budget and subsequent amendments thereto will be circulated for review and comment as provided in Section 9.4 but the budget shall be deemed to have been adopted by the Management Committee without a vote. 9.10 Budget Overruns; Program Changes. The Manager shall immediately notify the Management Committee of any material departure from an adopted Program and Budget. If the Manager exceeds an adopted Operating, Capital or Exploration Budget by more than 10%, then the excess over 10% (the "Excess Amount"), unless directly caused by an emergency expenditure made pursuant to Section 9.11, shall (a) subject to the provisions of the next sentence, be borne by the Participants according to their Participating Interests if the 10% overrun and the Excess Amount are added to the Budget by a unanimous vote called for by the 31 38 Manager at any time, of the Participants that are funding the Component of the Budget to which the overrun applies, or (b) if the overrun and the Excess Amount are not added to the Budget, the Excess Amount shall be borne by the Manager. Budget overruns of 10% or less or Budget overruns of more than 10% when approved by a vote of the Participants as provided in the preceding sentence shall be borne by the voting Participants in proportion to their respective Participating Interests as of the time the overrun occurs, except that (i) a non-voting Participant may affirmatively elect to share in the overrun and payment of the Excess Amount, or (ii) if a non-voting Participant fails to make such affirmative election, in the case of a Participant that is a Carried Participant pursuant to Section 9.6, or in the case of a Participant that has elected to contribute less, or not at all, to a Budget pursuant to Section 9.8, or in the case of a Participant that is having its share of a Budget funded pursuant to Section 9.7, the overrun shall be borne by the Carrying Participant or Participants, the funding Participant or Participants or the Project Financing or the Manager, as appropriate. 9.11 Emergency Expenditures. In case of emergency, the Manager may make emergency expenditures in taking any reasonable action it deems necessary to protect life, limb or property, to protect the Assets or to comply with law or government regulation. Emergency expenditures shall also include reasonable expenditures for events which are beyond the Manager's reasonable control and which do not result from a breach by the Manager of its standard of care, including, without limitation, repair of damages resulting from acts of God or accidents, defense of unanticipated litigation, costs associated with unanticipated changes in ores and the like. The Manager shall promptly notify the Participants of the emergency expenditure, and the Manager shall be reimbursed for all resulting costs by the Participants in proportion to their respective Participating Interests at the time the emergency expenditures are incurred. ARTICLE X ACCOUNTS AND SETTLEMENTS 10.1 Monthly Statements. The Manager shall promptly submit to the Management Committee monthly statements of account reflecting in reasonable detail and in accordance with the provisions of Exhibit B, the charges and credits to the Joint Account during the preceding month. 10.2 Cash Calls and Contributions. The Manager shall submit to each Participant prior to the last day of each month, a billing for estimated cash requirements for the next month on the basis of the adopted Budget, emergency expenditures under Section 9.11 or for any other expenditures authorized hereunder. The Manager may set off any cash calls or other contributions a Participant is required to make against proceeds from the sale of Products 32 39 deposited in the account of the Venture pursuant to Section 11.3. Within 10 days after receipt of each billing, each Participant shall advance to the Manager its proportionate share of the estimated amount net of any set off made by the Manager. Time is of the essence in the payment of such billings. The Manager may maintain a cash balance approximately equal to the rate of disbursement for up to a maximum of 60 days and shall promptly distribute to the Participants any funds in excess of that amount. All funds retained by the Manager in excess of immediate cash requirements shall be invested for the benefit of the Joint Account in interest-bearing accounts with a bank selected by the Manager. 10.3 Failure to Meet Cash Calls. If a Participant fails to meet any cash call or make any other contribution as provided in Section 10.2, the Manager shall notify such Participant, and such Participant shall have ten days from receipt of such notice to meet such cash call or make such contribution. If the Participant fails following such notice to meet such cash call or make such contribution, such Participant shall be in default, and the amounts of the defaulted cash call or contribution shall bear interest from the date due at an annual rate equal to five percentage points over the Prime Rate, but in no event shall said rate of interest exceed the maximum permitted by law. The non-defaulting Participant or Participants shall have those rights, remedies and elections specified in Section 6.4. 10.4 Audits. Within three months following the end of any calendar year (or, if the Management Committee has adopted an accounting period other than the calendar year, within three months after the end of such period), the Manager shall order an audit of the accounting and financial records for such calendar year (or other accounting period). The costs associated with such audit shall be charged to the Joint Account. All written exceptions to and claims upon the Manager for discrepancies disclosed by such audit shall be made not more than 12 months after receipt of the audit report. Failure to make any such exception or claim within the 12 month period shall mean the audit is correct and binding upon the Participants. The audits shall be conducted by a firm of certified public accountants selected by the Manager, unless otherwise agreed by the Management Committee. Additional audits may be requested by any Participant at any time, the costs of which shall be borne by the Participant requesting the same. Such additional audits shall not interfere with the performance of the audits chargeable to the Joint Account or alter the binding effect of such audits. ARTICLE XI DISPOSITION OF PRODUCTION 11.1 Taking in Kind. Subject to the provisions of Sections 6.4(g) and 6.5(b), each Participant shall take in kind or separately dispose of its share of all Products in accordance with 33 40 its Participating Interest. Any extra expenditure incurred in the taking in kind or separate disposition by any Participant of its proportionate share of Products shall be borne by such Participant. Nothing in this Agreement shall be construed as providing, directly or indirectly, for any joint or cooperative marketing or selling of Products or permitting the processing of Products of any parties other than the Participants at any processing facilities constructed by the Participants pursuant to this Agreement. The Manager shall give the Participants notice at least 10 days in advance of the delivery date upon which their respective shares of Products will be available. 11.2 Failure of Participant to Take in Kind. If a Participant fails to take in kind and has not authorized the Manager to act as its agent under Section 11.3, the Manager shall have the right, but not the obligation, for a period of time consistent with the minimum needs of the industry, but not to exceed one year, to purchase the Participant's share for its own account or to sell such share as agent for the Participant 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 the Manager is purchasing or selling a Participant's share of production, the Participant may elect by notice to the Manager to take in kind. The Manager shall be entitled to deduct from proceeds of any sale by it for the account of a Participant reasonable expenses incurred in such a sale. 11.3 Sale of Products. Each Participant hereby authorizes the Manager to negotiate on its behalf the terms of any marketing, smelting or refining agreement recommended to the Management Committee by the Manager. Such authority shall continue until revoked by written notice delivered to the Manager. Notwithstanding the foregoing, (i) each Participant shall be responsible for approving the final terms of any such agreement and shall execute the same on its own behalf; (ii) each Participant shall continue to have the right to take its share of production in kind as provided in this Article XI, and (iii) each Participant shall direct the purchaser of Products to deposit the proceeds from the sale of such Products into the account of the Venture. ARTICLE XII WITHDRAWAL AND TERMINATION 12.1 Breach of Agreement; Opportunity to Cure. (a) The failure of a Participant to keep or perform any material obligation arising under this Agreement shall constitute a default under this Agreement. Such a default, other than a default which is addressed by Section 8.4 regarding the Manager's removal or by Sections 6.4 and 10.3 regarding failure to meet a cash call or other required contribution, shall be subject to the provisions of this Section 12.1. 34 41 (b) In the event of an alleged default subject to the provisions of this Section 12.1, the Manager, or upon the failure or refusal of the Manager to do so, any non-defaulting Participant, shall first give the defaulting Participant notice of its intention to declare such alleged default to be a breach of this Agreement, specifying the particular default relied upon by it. The defaulting Participant shall have a reasonable time, but not more than 30 days after receipt of such notice, in which to cure or commence in good faith to cure or contest such alleged default. If such alleged default is cured, there shall be no breach hereunder with respect to such alleged default. If the defaulting Participant fails to cure or contest such default, any non-defaulting Participant may exercise any one or more of the remedies provided by law or in equity, including injunctive relief. The prevailing party shall be awarded all costs and expenses, including reasonable attorneys' fees, incurred in any such action. (c) Nothing contained herein shall preclude any Participant under appropriate circumstances from seeking a temporary injunction or restraining order. 12.2 Termination by Expiration or Agreement. This Agreement shall terminate as expressly provided in this Agreement, unless earlier terminated by written agreement. 12.3 Withdrawal. A Participant may elect to withdraw as a Participant from this Agreement by giving notice to the other Participants of the effective date of withdrawal, which shall be the later of the end of the then current Program and Budget or at least 30 days after the date of the notice. If upon such withdrawal only one Participant remains, this Agreement shall terminate, and the withdrawing Participant shall be deemed to have transferred to the remaining Participant, without cost and free and clear of royalties, liens or other encumbrances arising by, through or under such withdrawing Participant, except those exceptions to title described in Part I of Exhibit A and those to which all Participants have given their written consent after the date of this Agreement, all of its Participating Interest in the Assets and in this Agreement. If upon such withdrawal more than one Participant remains, this Agreement shall not terminate, but the withdrawing Participant shall be deemed to have transferred to the remaining Participants, in proportion to their respective Relative Interests, and without cost and free and clear of royalties, liens or other encumbrances arising by, through or under such withdrawing Participant, except those exceptions to title described in Part I of Exhibit A and those to which all Participants have given their written consent after the date of this Agreement, all of its Participating Interest in the Assets and in this Agreement. Any withdrawal under this Section 12.3 shall not relieve the withdrawing Participant of its share of any liability to third parties (including, without limitation, reclamation) which arises out of Operations conducted prior to such withdrawal, whether such liability is known or unknown at the time of the withdrawal and 35 42 whether such liability is asserted before or after the withdrawal. For purposes of this Section 12.3, the withdrawing Participant's share of such liabilities shall be equal to its Participating Interest at the time such liability was incurred. 12.4 Continuing Obligations. On termination of this Agreement under Section 12.2 or 12.3, the Participants shall remain liable for continuing obligations hereunder until final settlement of all accounts and for any liability (including, without limitation, reclamation) which arises out of Operations conducted during the term of the Agreement, whether such liability is known or unknown at the time of termination and whether such liability is asserted before or after termination. 12.5 Disposition of Assets on Termination. Promptly after termination of this Agreement under Section 12.2 or 12.3, the Manager shall take all action necessary to wind up the activities of the Venture, and all costs and expenses incurred in connection with the termination of the Venture shall be expenses chargeable to the Venture. The Assets shall first be paid, applied, or distributed in satisfaction of all liabilities of the Venture to third parties and then to satisfy any debts, obligations, or liabilities owed to the Participants. Before distributing any funds or Assets to Participants, the Manager shall have the right to segregate amounts which, in the Manager's reasonable judgment, are necessary to discharge continuing obligations or to purchase for the account of Participants, bonds or other securities for the performance of such obligations. The foregoing shall not be construed to include the repayment of any Participant's capital contributions. Thereafter, any remaining cash and all other Assets shall be distributed (in undivided interests unless otherwise agreed) to the Participants, first in the ratio and to the extent of their respective Equity Account Balances and then in proportion to their respective Participating Interests, subject to any dilution, reduction, or termination of such Participating Interests as may have occurred pursuant to the terms of this Agreement. No Participant shall receive a distribution of any interest in Products or proceeds from the sale thereof if such Participant's Participating Interest therein has been terminated pursuant to this Agreement. 12.6 Non-Compete Covenants. A Participant that withdraws pursuant to Section 12.3, or is deemed to have withdrawn pursuant to Sections 6.4 or 6.5, shall not directly or indirectly acquire any interest in property within the Area of Interest for 12 months after the effective date of withdrawal. If a withdrawing Participant, or the Affiliate of a withdrawing Participant, breaches this Section 12.6, such Participant or Affiliate shall be obligated to offer to convey to the non-withdrawing Participant or Participants, without cost, any such property or interest acquired. Such offer shall be made in writing and can be accepted by the non-withdrawing Participant or Participants at any time within 45 36 43 days after it is received by such non- withdrawing Participant or Participants. 12.7 Right to Data after Termination. After termination of this Agreement pursuant to Section 12.2 or 12.3, each Participant shall be entitled to copies of all information acquired hereunder before the effective date of termination not previously furnished to it, but the terminating or withdrawing Participant shall not be entitled to any such copies after any other termination or any withdrawal. 12.8 Continuing Authority. Upon termination of this Agreement under Section 12.2, or upon the deemed withdrawal of a Participant pursuant to Section 6.4 or 6.5 or the withdrawal of a Participant pursuant to Section 12.3 such that only one Participant remains, the Manager shall have the power and authority, subject to control of the Management Committee, if any, to do all things on behalf of the Participants or the sole remaining Participant which are reasonably necessary or convenient to: (a) wind up Operations; and (b) complete any transaction and satisfy any obligation, unfinished or unsatisfied, at the time of such termination or withdrawal, if the transaction or obligation arises out of Operations prior to such termination or withdrawal. The Manager shall have the power and authority to grant or receive extensions of time or change the method of payment of an already existing liability or obligation, prosecute and defend actions on behalf of the Participants and the Venture, mortgage Assets, and take any other reasonable action in any matter with respect to which the former Participants continue to have, or appear or are alleged to have, a common interest or a common liability. ARTICLE XIII ACQUISITIONS WITHIN AREA OF INTEREST 13.1 General.

The acquiring Participant's notice shall describe in detail the acquisition, the lands and minerals covered thereby, the cost thereof, and the reasons why the 37 44 acquiring Participant believes that the acquisition of the interest is in the best interests of the Participants under this Agreement. In addition to such notice, the acquiring Participant shall make any and all information concerning the acquired interest available for inspection by the other Participants. 13.3 Option Exercised. If, within 30 days after receiving the acquiring Participant's notice, all other Participants notify the acquiring Participant of their election to accept a proportionate interest in the acquired interest equal to its Participating Interest, the acquiring Participant shall convey to the other Participants, by special warranty deed, such proportionate undivided interests therein. The acquired interest shall become a part of the Properties for all purposes of this Agreement immediately upon the notice of the other Participants' election to accept the proportionate interest therein. The other Participants shall promptly pay to the acquiring Participant their proportionate shares of the latter's actual out-of-pocket acquisition costs. 13.4 Option Partially Exercised or Not Exercised. (a) If only one other Participant gives notice within the 30 day period set forth in Section 13.3, the non-notifying Participant shall have no interest in the acquired interest and the acquired interest shall not become a part of the Properties or be subject to this Agreement. The acquiring Participant and the notifying Participant shall follow the procedures set out in Section 13.3 and the notifying Participant shall receive and pay for an interest in the interest equal to its Relative Interest and the acquiring Participant and the notifying Participant shall then own the interest independently of the Venture. (b) If no other Participant gives such notice within the 30 day period set forth in Section 13.3, the non-notifying Participants shall have no interest in the acquired interest, and the acquired interest shall not become a part of the Properties or be subject to this Agreement. 13.5 Special Provisions Related To The Norbritex Properties.

ARTICLE XIV ABANDONMENT AND SURRENDER OF PROPERTIES 14.1 Surrender or Abandonment of Property. The Management Committee may authorize the Manager to surrender or abandon part or all of the Properties. If the Management Committee authorizes any such surrender or abandonment over the objection of a Participant or Participants, the Participant or Participants that desire to abandon or surrender shall assign to the objecting Participant or to the objecting Participants in proportion to their Relative Interests, by special warranty deed and without cost to the surrendering Participant or Participants, all of the surrendering Participant's or Participants' interest in the property to be 39 46 abandoned or surrendered, and the abandoned or surrendered property shall cease to be part of the Properties. 14.2 Reacquisition.

Any proposed transferee must represent and warrant to the Venture that the proposed transferee's admission would not result in any such prohibition or limitation; (c) No Transfer permitted by this Article XV shall relieve the transferring Participant of its share of any liability (including, without limitation, reclamation liability) which arises out of Operations conducted prior to such Transfer, whether such 40 47 liability is known or unknown at the time of Transfer and whether such liability is asserted before or after the Transfer; (d) The transferring Participant and the transferee shall bear all tax consequences of the Transfer; (e) In the event of a Transfer of less than all of a Participating Interest other than to another Participant, the transferring Participant and its transferee shall act and be treated as one Participant; (f) No Participant shall Transfer any interest in this Agreement or the Assets except by Transfer of part or all of its Participating Interest; (g) If the Transfer is the grant of a security interest to a third party by mortgage, deed of trust, pledge, lien or other encumbrance of any interest in this Agreement, any Participating Interest or the Assets to secure a loan or other indebtedness of a Participant in a bona fide transaction, such security interest shall be subordinate to the terms of this Agreement and the rights and interests of the other Participants hereunder other than as provided in Section 6.4(c). Upon any foreclosure or other enforcement of rights in the security interest, the acquiring third party shall be deemed to have assumed the position of the encumbering Participant with respect to this Agreement and the other Participants, and it shall comply with and be bound by the terms and conditions of this Agreement; (h) If a sale or other commitment or disposition of Products or proceeds from the sale of Products by a Participant upon distribution to it pursuant to Article XI creates in a third party a security interest in Products or proceeds therefrom prior to such distribution, such sales, commitment or disposition shall be subject to the terms and conditions of this Agreement; (i) For purposes of the notice required under Section 15.3(a), the purchase price for all Transfers shall be expressed in U.S. dollars, regardless of whether the purchase price calls for the payment of money, and to the extent the purchase price includes property other than Assets, such purchase price shall describe the portion of the purchase price attributable to Assets; (j) The following shall not be deemed a Transfer, nor shall the transferee be deemed an assignee for purposes of this Agreement: (i) a transfer by a Participant to an Affiliate, provided that the Participant shall continue to be liable for all obligations hereunder, and provided further that any transfer of less than all of a Participant's Participating Interest shall be subject to the provisions of Section 15.2(e); 41 48 (ii) a transfer by a Participant of all or substantially all of its assets, or a sale of all shares of a corporate Participant by its parent corporation or other entity holding such shares, or such other corporate merger, consolidation or reorganization of a Participant, by which the surviving entity shall possess substantially all of the property rights and interests, or all of the shares, and shall be subject to substantially all of the liabilities and obligations of that Participant; provided, however, that the interest of the Participant in this Agreement and the Assets and its Participating Interest are not substantially all of assets of the Participant; and provided further, however, that the transferee is or following the Transfer will be substantially similar in financial strength to the transferring Participant; (iii) an incorporation of a Participant; or (iv) a transfer by a Participant to a joint venture or partnership in which such Participant is a participating venturer or partner with a majority or controlling interest, provided that any transfer of less than all of a Participant's Participating Interest shall be subject to the provisions of Section 15.2(e); and (k) If the interest of a Participant in this Agreement and the Assets and its Participating Interest are all or substantially all of the assets of the Participant, or are not all or substantially all of its assets but the financial strength of the transferee will be substantially less than the financial strength of the transferring Participant, a sale of all shares of a corporate Participant or the sale of all shares of any Affiliate of a Participant (by which the Participant is effectively subject to new ownership or management) or such other corporate merger, consolidation or reorganization, shall be deemed a Transfer. A transfer by a Participant to a joint venture or partnership in which such Participant is a participating venturer or partner with a minority or non- controlling interest shall also be deemed a Transfer, provided that any transfer of less than all of a Participant's Participating Interest shall be subject to the provisions of Section 15.2(e). 15.3 Preemptive Right. Except as otherwise provided in Section 15.4, if a Participant desires to Transfer all or any part of its interest in this Agreement, any Participating Interest, or the Assets, the other Participants shall have a preemptive right to acquire such interests as provided in this Section 15.3. (a) A Participant intending to Transfer all or any part of its interest in this Agreement, its Participating Interest, or the Assets shall promptly notify the other Participants of its intentions. The notice shall state the price and all other pertinent terms and conditions of the intended Transfer, and shall be accompanied by a copy of the offer or contract for sale. The 42 49 other Participants shall have 30 days from the date such notice is delivered to notify the transferring Participant whether they elect to acquire the offered interest at the price stated in the notice and on the same terms and conditions as set forth in the notice. If one or more Participants so elect, the Transfer shall be consummated promptly after notice of such election is delivered to the transferring Participant. If more than one Participant does so elect, the offered interest shall be transferred to each electing Participant in proportion to its Relative Interest. If only one Participant does so elect, the offered interest shall be transferred to the electing Participant. (b) If all other Participants fail to so elect within the period provided for in Section 15.3(a), the transferring Participant shall have 180 days following the expiration of such period to consummate the Transfer to a third party at the price stated in the notice and on terms and conditions no less favorable than those stated in the notice required in Section 15.3(a). (c) If the transferring Participant fails to consummate the Transfer to a third party within the period set forth in Section 15.3(b), the preemptive right of the other Participants in such offered interest shall be deemed to be revived. Any subsequent proposal to Transfer such interest shall be conducted in accordance with all of the procedures set forth in this Section 15.3. (d) Upon a foreclosure or other enforcement of rights in a security interest created by mortgage, deed of trust, lien or other encumbrance of any interest in this Agreement or the Assets or its Participating Interest made to secure a loan or other indebtedness of a Participant (herein a "Foreclosure or Other Sale"), each other Participant shall have a preemptive right to acquire the interests purchased at the Foreclosure or Other Sale from the acquiring third party at the price paid by the acquiring third party, which right shall be exercised within 30 days after such sale occurs, by notice given to the acquiring third party, reflecting each such other Participant's election to acquire such interest at the price paid by such acquiring third party in the Foreclosure or Other Sale. If one or more of such other Participants does so elect, the Transfer to such Participant or Participants shall be consummated promptly after such notice. The preemptive right created under this Section shall be subject to all of the redemption rights or other rights to recover property created by law. (e) If a Participant's interest in this Agreement and the Assets and its Participating Interest are all or substantially all of the assets of such Participant, or are not all or substantially all of the assets but the financial strength of the transferee, if any, will be substantially less than the financial strength of the transferring Participant, the preemptive right created under this Section shall apply to a transfer of all shares 43 50 of a corporate Participant or the sale of all shares of any Affiliate of a Participant (by which the Participant is effectively subject to new ownership or management) or such other corporate merger, consolidation or reorganization. A transfer by a Participant to a joint venture or partnership in which such Participant is a participating venturer or partner with a minority or non-controlling interest shall also be subject to the preemptive right created under this Section. (f) The sale of a Participant's interest in this Agreement and the Assets and its Participating Interest pursuant to a bankruptcy or similar proceeding shall be subject to the preemptive right of the other Participants created under this Section. 15.4 Exceptions to Preemptive Right.

Notwithstanding anything else contained in this Article XV, a Transfer by CSX of all of its interest in this Agreement and the Assets and its Participating Interest or sale of all shares of the stock of CSX by its parent corporation shall not be subject to (a) Section 15.2(c), so long as CSX demonstrates to the reasonable satisfaction of Greens Creek and Hecla that the transferee has a net worth sufficient to cover CSX's share of estimated reclamation liabilities as described in that certain Greens Creek Mine Reclamation Cost Estimate dated July 10, 1992 filed with the United States Forest Service, as may be amended from time to time hereafter, provided that no amendments within the six month period preceding the transfer shall be considered in determining the sufficiency of the transferee's net worth; and (b) Section 15.3. Upon such Transfer or sale, the exceptions provided by this Section 15.5 shall terminate and the transferee shall not be entitled to the exceptions contained in this Section 15.5 but shall be subject to all of the provisions of 44 51 this Agreement. For purposes of this Section 15.5, the provisions of Sections 15.2(j) and (k) shall not apply to determine when a transaction constitutes a Transfer, so that any Transfer by CSX of its interest in this Agreement and the Assets and its Participating Interest or sale of all shares of the stock of CSX shall be subject to all other provisions of Section 15.2 except as specifically provided in this Section 15.5. 15.6 Exceptions for Greens Creek and Hecla.

Upon the Transfer or sale, the exceptions provided by this Section 15.6 shall terminate with respect to the interest transferred or sold and the transferee shall not be entitled to the exceptions contained in this Section 15.6 but shall be subject to all of the provisions of this Agreement. For purposes of this Section 15.6, the provisions of Sections 15.2(j) and (k) shall not apply to determine when a transaction constitutes a Transfer, so that any Transfer by Greens Creek or Hecla of its interest in this Agreement and the Assets and its Participating Interest or the sale of all shares of the stock of Greens Creek shall be subject to all other provisions of Section 15.2. ARTICLE XVI PROJECT FINANCING 16.1 Ownership, Transfer and Encumbrance of Participating Interests. Each of the Participants may fund its obligations under this Agreement (except for obligations arising under Section 9.7(b) which will be financed or funded by the Manager) through a financing arranged by the Participant, the repayment of which is secured by a Lien, as defined below, Any such financing shall be 45 52 deemed to be a "Project Financing" and shall be subject to the provisions of this Article XVI. (a) The Manager will maintain a record (the "Ownership Record") of the persons owning Participating Interests in the Venture, their respective Participating Interest amounts and dates of ownership. On the request of any Participant, the Manager will also record any direct or indirect lien, pledge, mortgage or other security interest covering that Participant's Participating Interest in the Venture (or any part thereof), the capital stock of such Participant, and/or any other collateral assignment of the related rights of such Participant under this Agreement (collectively, a "Lien") by noting such Lien in the Ownership Record. A Lien so noted is referred to in this Agreement as a "Recorded Lien" and the holder thereof, a "Lienholder". The Manager will not be responsible for updating the Lien information on the Ownership Record, except when requested to do so by a Participant. The Manager will not be liable to any person for any actions taken in connection with maintaining the Ownership Record. A Participant may remove a Recorded Lien from the Ownership Record by delivering to the Manager an executed form of satisfaction relating to such Recorded Lien. Should any inconsistency or conflict arise between the Ownership Record and any applicable public record as to the relative priority of any Recorded Lien, the public records shall control in determining the relative rights and priorities of third parties. (b) No direct or indirect Transfer of a Participating Interest subject to a Recorded Lien shall be effective unless prior written notice of such action is delivered to the existing Lienholder not less than 30 days prior to consummation of such action. Any such Transfer shall be subject to such Recorded Lien. 16.2 Lienholder Rights and Obligations on Foreclosure. (a) In the event that the Lienholder forecloses upon the Participating Interest (or capital stock) of a Participant (the "Affected Participant") subject to its Lien or exercises rights prior to a foreclosure pursuant to a security instrument ("Pre-Foreclosure Rights"), then, subject to compliance with the provisions of Section 16.2(b), the Lienholder will be entitled to exercise all rights of the Affected Participant with respect to the Venture and this Agreement (including, without limitation, the right to vote such Participating Interest in accordance with the provisions of this Agreement, the right to otherwise participate in the management and administration of the Venture's business and affairs, the right to obtain information regarding the Venture and its transactions and the right to inspect the books and records of the Venture). If a Lienholder initiates foreclosure proceedings or exercises Pre-Foreclosure Rights with respect to the Participating Interests (or capital stock) of more than one Affected Participant, the Lienholder may vote such Participating Interest on behalf of, and in substitution of the vote of, such Participant until such 46 53 time as either (i) another Participant or other Participants purchases the collateral pursuant to Section 15.3(d) or (ii) the collateral is sold at a foreclosure sale. (b) A Lienholder shall be permitted to exercise Preforeclosure Rights and foreclose upon its Lien on a Participating Interest if such Lienholder delivers to the Manager (or, if the Manager is the Affected Participant, to each other Participant) either (i) a copy of an involuntary or voluntary bankruptcy petition (or an equivalent document under state law) filed in connection with the bankruptcy or insolvency of the Affected Participant, (ii) a copy of a preliminary injunctive order (or equivalent judicial action), issued by a court of competent jurisdiction, permitting the Lienholder to exercise such Pre-Foreclosure Rights or to foreclose or (iii) a copy of a declaratory judgment (or equivalent judicial action) issued by a court of competent jurisdiction, declaring that the Lienholder is entitled to exercise such Pre-Foreclosure Rights or to foreclose. (c) Upon compliance with the provisions of Section 16.2(b), a Lienholder may deliver written notice to the Manager (or, if the Manager is the Affected Participant, to each other Participant) initiating the procedure set forth in this Section 16.2(c) and identifying the Affected Participant, the collateral subject to the Recorded Lien, and the aggregate amount of the principal of, accrued interest on and other amounts owing with respect to the financing secured by the Recorded Lien (the "Accelerated Loan Amount"); provided that a Lienholder exercising Pre-Foreclosure Rights shall deliver a notice pursuant to this Section 16.2(c) no later than 90 days after the delivery of the documentation referred to in Section 16.2(b). Each Participant that is not an Affected Participant shall have the right and option, exercisable within 30 days of the date of delivery of such notice, to purchase (and the Lienholder and the Affected Participant shall be obligated to convey) all, but not less than all, the collateral subject to the Recorded Lien, upon payment to the Lienholder of the Accelerated Loan Amount. If two or more Participants desire to purchase such collateral, each such Participant shall be entitled to purchase their Relative Interests in the collateral. (d) In exercising Pre-Foreclosure Rights, each Lienholder will be subject to the provisions of this Agreement, as such provisions would apply to the Affected Participant. (e) Any action taken by the Lienholder in the exercise of Pre-Foreclosure Rights shall bind such Affected Participant. The Affected Participant waives any and all claims against the other Participants arising out of the exercise by a Lienholder of Pre-Foreclosure Rights. 16.3 Waiver of Preferential Purchase Right. The following actions will not be subject to the preemptive rights set forth in 47 54 Section 15.3 (provided that written notice of such action shall be given to the Manager at least 10 days prior to the effectiveness of any transaction pursuant to paragraphs (a) and (b) below and no more than 30 days after the exercise of Pre- Foreclosure Rights pursuant to paragraph (c) below): (a) The grant of a Lien covering the Participating Interest of a Participant to any bank or other financial institution to secure financing obtained by such Participant to fund its portion of any approved Program and Budget (a "Financing"). (b) The grant of a Lien covering the capital stock of a Participant to secure Financing. (c) Any extension of Pre-Foreclosure Rights by a Lienholder pursuant to any Financing with respect to the Participating Interest or capital stock of a Participant.

Receipts from the production, sale, use or other disposition of Assets or Products shall be determined as follows: (a) If Products derived from the Properties are sold to a smelter, refiner or other purchaser (other than the Payor or Affiliates of the Payor), Receipts shall equal the amount of revenues actually received by the Payor from the smelter, refiner or other purchaser of Products, plus any bonuses and subsidies, less all penalties, assaying and sampling charges whether deducted by the purchaser or paid or incurred by the Payor; (b) Except as provided in (c) below, if Products derived from the Properties are sold to the Payor or an Affiliate of the Payor or if any Participant takes its share of Products in kind under Section 11.1 of the Agreement, then for purposes of determining Receipts, such Products shall be deemed conclusively 1 70 to have been sold at a price equal to the fair market value of a sale to arm's length purchasers; (c) If the Payor produces as a final product or has produced as a final product through a tolling/refining contract or any other transaction that results in the Payor owning title to fine gold and/or silver bullion or dore bullion produced from the Properties, and such products have not been sold within 30 days after the end of the month in which the final product was produced, then Receipts shall mean the amount of fine gold and/or silver bullion produced or the amount of payable gold and/or silver contained in dore bullion produced from the Properties multiplied by (i) for gold, the average London Bullion Market Association P.M. Gold Fixing for the calendar quarter of production and (ii) for silver, the average London Bullion Market Association daily Silver Fixing on the date such bullion is made available to the Payor by the smelter, mint or refiner that processes such Products. The average price for the calendar quarter shall be determined by dividing the sum of all daily prices posted during the calendar quarter by the number of days that prices were posted. The posted price shall be obtained from The Wall Street Journal, Reuters, or other reliable source. If either the London Bullion Brokers P.M. Gold Fixing or the London Bullion Market Association daily Silver Fixing ceases to be published, the parties shall agree upon a similar alternative method for determining the average daily spot market price for gold or silver, as the case may be. In any case, the Royalty Holder shall have no right to participate in any hedging, trading or other similar transaction involving Products derived from the Properties; and (d) If Assets are leased, sold, rented or used by the Payor other than with respect to the Properties, Receipts shall be the actual revenues received; provided, however, that if such sale, lease, rental or use is not an arms-length transaction, the fair market value of such transaction shall be used to determine Receipts. 4.

D. COSTS OF COMMON FACILITIES. Where any Capital Expenditures or Operating Expenses are paid with respect to the mining, milling, processing, selling or delivering of Products produced from the Properties in conjunction with the mining, milling, processing, selling or delivering of minerals produced from other properties controlled by the Payor, such Capital Expenditures and Operating Expenses shall be fairly allocated and apportioned in accordance with generally accepted practices in the mining industry. E. PAYMENTS OF NET PROCEEDS. The Payor shall deliver to the Royalty Holder a payment equal to the percentage, as set forth in the Agreement, of all Net Proceeds realized by the Payor during any calendar quarter within 30 days after the end of said calendar quarter, together with a copy of the accounting made in connection with such payment.

The Royalty Holder shall be deemed to have waived any right it may have had to object to a payment made for any calendar quarter, unless it provides notice in writing of such objection within 24 months after receipt of final payment for the calendar quarter. If the parties are unable to resolve the dispute within 60 days after the receipt of such notice, the dispute shall be resolved by arbitration in Anchorage, Alaska pursuant to the commercial arbitration rules of the American Arbitration Association. The resolution pursuant to such arbitration shall be binding on the parties. Alternatively, the parties may elect to submit the dispute to a mutually acceptable certified public accountant, or firm of certified public accountants, for a binding resolution thereof. Unless the parties agree to share the costs of arbitration, the arbitrator shall determine what part of the costs and expenses incurred in any such proceeding shall be borne by each party participating in the arbitration. G. GENERAL. 1. Unless otherwise specified, capitalized terms used herein shall have the same meaning as given to them in the Agreement to which this Exhibit D is attached. 2. Accurate records of tonnage, volume of products, analyses of products, weight, moisture, assays of pay metal content and other records related to the computation of Net Proceeds hereunder shall be kept by the Payor. 3. The Royalty Holder or its authorized representative on not less than 5 days' notice to the Payor, may enter upon all surface and subsurface portions of the Properties for the purpose of inspecting the Properties, all improvements thereto and operations thereon, and may inspect and copy all records and data pertaining to the computation of its interest, including without limitation such records and data which are maintained electronically. The Royalty Holder or its authorized representative shall enter the Properties at the Royalty Holder's own risk and may not unreasonably hinder operations on or pertaining to the Properties. The Royalty Holder shall indemnify and hold harmless all Participants and their Affiliates (including without limitation direct and indirect parent companies), and its or their respective directors, officers, shareholders, employees, agents and attorneys, from and against any Liabilities which may be imposed upon, asserted against or incurred by any of them by reason of injury to the Royalty Holder or any of its agents or representatives caused by the Royalty Holder's exercise of its rights herein. 5 74 4. All notices or communications hereunder shall be made and effective in accordance with the provisions of the Agreement. 5. The Net Proceeds interest shall attach to any amendments, relocations or conversions of any mining claims or leases comprising the Properties, or to any renewals or extensions of leases, and to any mineral rights acquired by the Payor and any Affiliates in lands embraced within any mining claims or leases comprising the Properties within one year after the loss or relinquishment of any mining claim or lease comprising the Properties. The Net Proceeds interest shall be a real property interest that runs with the Properties and shall be applicable to any person who produces and sells Products from the Properties. 6. All information and data provided to the Royalty Holder shall be subject to the confidentiality provisions of Article XVII of the Agreement. 7. The Payor shall have the right to commingle ore and minerals from the Properties with ore from other lands and properties; provided, however, that the Payor shall calculate from representative samples the average grade of the ore and shall weigh (or calculate by volume) the ore before commingling. If concentrates are produced from the commingled ores by the Payor, the Payor shall also calculate from representative samples the average recovery percentage for all concentrates produced during the calendar quarter. In obtaining representative samples, calculating the average grade of the ore and average recovery percentages, the Payor may use any reasonable procedures that are commonly accepted in the mining and metallurgical industry which it believes suitable for the type of mining and processing activity being conducted and, in the absence of fraud, its choice of such procedures shall be final and binding on the Royalty Holder. In addition, comparable procedures may be used by the Payor to apportion among the commingled ores penalty charges, if any, imposed by the purchaser of such ore or concentrates. In the case of any dispute regarding the reasonableness of any procedure adopted by Payor, and if that dispute cannot be resolved by the parties, then the dispute should be submitted to arbitration, pursuant to Section F.2. Fraud should not be the standard for resolving any such dispute; rather, the adoption of any such procedure should be subject to a determination of reasonableness. 6 75 EXHIBIT E INSURANCE The Manager shall, at all times while conducting Operations, comply fully with the applicable worker's compensation laws and purchase, or provide through self-insurance, protection for the Participants comparable to that provided under standard form insurance policies for (i) comprehensive public liability and property damage with combined limits of Ten Million Dollars for bodily injury and property damage; (ii) automobile insurance with combined limits of One Million Dollars; and (iii) adequate and reasonable insurance against risk of fire, earthquake and flood, and other risks ordinarily insured against in similar operations.

This memorandum is executed for the purpose of affording notice of the existence of the Agreement and the terms and provisions thereof, which terms and provisions are incorporated herein by reference for all purposes. This memorandum is not intended to alter or vary the terms of the Agreement. All capitalized words in this memorandum have the same meaning as assigned to them in the Agreement. Some of the terms and provisions of the Agreement are hereby summarized as follows: 1. The Participants have the following Participating Interests: Greens Creek - 57.7505% Hecla - 29.7331% CSX - 12.5164% 1 81 Although record title to the Properties may appear in the name of the Manager for the benefit of the Venture or in the name of the Participants, the Participants shall hold their interests in the Properties as tenants in common in proportion to their Participating Interests as such interests might be adjusted from time-to-time, and the Participants shall, from time-to-time, execute such conveyances as are necessary to effectuate such ownership. 2.
