The Parties do not intend to create, and this Agreement shall not be construed to create, any mining, commercial or other partnership. Neither Party, nor any of its shareholders, members, directors, officers, managers, employees, agents and attorneys-in-fact, or its Affiliates, shall act for or assume any obligation or responsibility on behalf of the other Party, except as otherwise expressly provided herein, and any such action or assumption by a Party’s managers, members, directors, officers, employees, agents and attorneys-in-fact, or Affiliates, shall be a breach by such Party of this Agreement.

Each Party shall be responsible only for its obligations as herein set out and shall be liable only for its share of the costs and expenses as provided herein, and it is the express purpose and intention of the Parties that the rights acquired hereunder shall be as tenants in common.

     6.2 Other Business Opportunities. Except as expressly provided in this Agreement, each Party shall have the right to engage in and receive full

7

benefits from any independent business activities or operations, whether or not competitive with the endeavor contemplated by this Agreement, without consulting with, or incurring any obligation to, the other Party.

Neither Party shall have any obligation to the other with respect to an opportunity to acquire any property outside the Real Property at any time or within the Real Property after the termination of the endeavor contemplated by this Agreement.

     6.6 No Third Party Beneficiary Rights. This Agreement benefits only the Parties and their respective successors and assigns, and, except as specifically set forth herein, shall not be construed to create third party beneficiary rights in any other party or in any governmental organization or agency.

7. MANAGEMENT AND OPERATIONS

     7.1 Sole Operator. Del Toro shall be the manager of the joint endeavor memorialized herein, and, as such, shall promptly hereafter form a single purpose entity (“SPE”) that, subject to tax counsel’s guidance and direction, is presently to be a California limited liability company, in which Del Toro and Bowerman shall be the only equity holders (with the stake of each equaling its Participating Interest (as defined below)). The SPE shall act as the sole and exclusive operator entitled to exercise, operate, administer and manage the Permitted Uses during the Term, and nothing more. Subject to Section 7.2, the other provisions herein, and applicable law, Del Toro shall have full, exclusive and complete discretion, power and authority to manage, control, administer and operate the SPE’s business and affairs on the Claims for the Permitted Uses, and to make all decisions affecting such business and affairs.

8

     7.2 Thirty-six Month Work Plan. Notwithstanding the provisions of Section 7.1, the Parties have approved a budget and work plan for the SPE’s first thirty-six months of work on and about the Claims (the “36-Month Work Plan”). A copy of that 36-Month Work Plan is attached hereto as Exhibit B. Del Toro shall use its best efforts to cause the SPE to perform and comply with the 36-Month Work Plan in all material respects, pursuant to the standard of care set forth in Section 7.7. The method and manner of performing and complying with the 36-Month Work Plan shall be left to Del Toro’s sole discretion. The 36-Month Work Plan shall not be amended, altered or otherwise changed without the written consent of both Parties. The first one million five hundred thousand dollars ($1,500,000) expended under the 36-Month Work Plan shall be paid into the SPE by Del Toro for such expenditure. For avoidance of doubt, Bowerman’s financial obligations hereunder shall be entirely carried and stayed until such time as Del Toro has expended $1,500,000 under the 36-Month Work Plan (“Carry Period”).

     7.3 Emergency or Unexpected Expenditures. In case of emergency occurring during performance of the 36-Month Work Plan, Del Toro may take any reasonable action it deems necessary to protect life or property, to protect the Claims, or to comply with Laws. Del Toro may advance reasonable expenditures for unexpected events that are beyond its reasonable control and that do not result from a breach by it of its standard of care. Del Toro shall promptly notify Bowerman of the emergency or unexpected expenditure.

     7.4 Work During Remainder of Term. Upon completion of the 36-Month Work Plan and for the remainder of the Term, Del Toro shall prepare and submit to Bowerman a budget and work plan for each such year. Bowerman shall not have any rights to approve or disapprove the same, and such budgets and work plans shall be solely for Bowerman’s information. Notwithstanding the preceding sentence, Del Toro shall use its best efforts to perform and comply with any and all such further work plans in all material respects, pursuant to the standard of care set forth in Section 7.7. The method and manner of performing and complying with such work plans shall be left to Del Toro’s sole discretion. Such work plans shall not be materially amended, altered or otherwise changed without Notice to Bowerman of such changes.

     7.5 Specific Power and Authority of Del Toro. In addition to the other duties and responsibilities set forth in this Section 7, and subject to the other terms and provisions of this Agreement, Del Toro shall have the following specific powers and duties, which shall be discharged in accordance with the 36-Month Work Plan and all other adopted work plans:

necessary to carry out the work programs, and shall promptly advise Bowerman if it lacks sufficient funds to carry out its responsibilities under this Agreement.

          7.5.3 Acquisition of Material. Del Toro shall use reasonable efforts to: (i) purchase or otherwise acquire all material, supplies, equipment, water, utility and transportation services required for operations, such purchases and acquisitions to be made to the extent reasonably possible on the best terms available, taking into account all of the circumstances, (ii) obtain such customary warranties and guarantees as are available in connection with such purchases and acquisitions, and (iii) keep the Claims and Real Property free and clear of all Encumbrances, except any mechanic’s or materialmen’s liens (which shall be contested, released or discharged in a diligent matter) or Encumbrances specifically approved by Bowerman.

Del Toro shall: (i) make or arrange for all payments required by leases, licenses, permits, contracts and other agreements with third parties related to the Claims and/or the Real Property; (ii) pay all taxes, assessments and like charges on operations and/or the Claims, except taxes determined or measured by a Party’s sales revenue or net income, and otherwise promptly pay and discharge expenses incurred in operations; provided, however, that Del Toro shall have the right to contest (in the courts or otherwise) the validity or amount of any taxes, assessments or charges or take other reasonable steps or proceedings to seek a reduction or readjustment prior to payment, but in no event shall Del Toro permit or allow title to the Claims to be lost as the result of the nonpayment of any taxes, assessments or like charges; and (iii) do all other acts reasonably necessary to maintain the Claims.

          7.5.6 Compliance with Laws. Del Toro shall (i) apply for all necessary permits, licenses and approvals relating to operations with respect to the Claims, (ii) comply with all Laws, including Environmental Laws, (iii) notify Bowerman promptly of any actual or alleged substantial violations thereof, and (iv) maintain records and prepare and file all reports or notices required for or as a result of operation of the Claims.

If any such violation occurs, Del Toro shall timely cure or dispose of such violation on behalf of both Parties through performance, payment of fines and penalties, or both,

10

and the cost thereof shall be charged to the Account (as defined below).

          7.5.7 Litigation.

The SPE shall be the primary insured, but Del Toro and Bowerman shall be named as additional insured parties under all such policies. Each Party shall self-insure or purchase for its own account such additional insurance coverage as it deems warranted.

          7.5.9 Limitations. The consent of Bowerman is required before Del Toro may, through the SPE or otherwise, (i) abandon or surrender any of the Claims, (ii) begin a liquidation or initiate wind up of operation of the Claims, or (iii) dispose of material Operating Assets necessary to achieve the purposes of this Agreement.

Del Toro shall not be liable on account of any determination by a court or governmental agency that any such document submitted by Del Toro does not comply with applicable requirements (provided that such document is prepared and recorded or filed in accordance with Del Toro’s standard of care under Section 7.7) .

          7.5.12 Relocation.

Unless Bowerman expressly notifies Del Toro that Bowerman will sell its share of Products, Bowerman will be deemed to have authorized Del Toro to sell to third parties Bowerman’s share of Products and Del Toro shall have the right, but not the obligation, for a period of time consistent with the minimum needs of the

14

industry, but not to exceed one (1) year from the Notice date described in Section 8.4 above, to purchase Bowerman’s share for its own account at not less than the prevailing market price in San Francisco, California.

9. ACCOUNTING AND REPORTING PROCEDURES

Such records shall be retained for the duration of the longer of the period allowed the Parties for audit or the period necessary to comply with tax and other regulatory requirements. The records shall reflect all obligations, advances and credits of the Parties.

     9.2 Cash Management Accounts. Del Toro shall maintain one or more separate cash management accounts in the SPE’s name for the payment of all expenses and the deposit of all cash receipts for operation of the Claims (collectively, the “Account”).

          9.3.4 Del Toro’s actual cost of established plans for employees’ group life insurance, hospitalization, pension, retirement, stock purchase, thrift, bonus (except production or incentive bonus plans under a union contract based on actual rates of production, cost savings and other production factors, and similar non-union bonus plans customary in the industry or necessary to attract competent employees, which bonus payments shall be considered salaries and wages under Section 9.3.2 rather than payments under an employee benefit plan) and other benefit plans of a like nature applicable to salaries and wages chargeable under Section 9.3.2, provided that the plans are limited to the extent feasible to those customary in the industry;

          9.3.5 Cost of assessments imposed by governmental authority that are applicable to salaries and wages chargeable under Section 9.3.2, including all penalties except those resulting from the willful misconduct or gross negligence of Del Toro;

          9.3.7 The actual cost of procuring, operating, supplying, maintaining, repairing, servicing and insuring the machinery, equipment, facilities and improvements to the Real Property that are owned by Del Toro or licensed by Del Toro from any third party (including an Affiliate of Bowerman or its parent corporation, as in part or all further detailed herein) and used in operations or to provide support or utility services to operations (“Operating Assets”), which will be charged at rates commensurate with the actual costs of ownership and operation of such machinery, equipment and facilities; provided that such rates shall (i) include costs of maintenance, repairs, supplies, and other operating expenses, insurance, taxes, depreciation and interest at a rate not to exceed

16

          9.3.10 Net premiums paid for insurance for Operations for the protection of the Parties; provided that, when Operations are conducted in an area where Del Toro may self-insure for Worker’s Compensation and/or Employer’s Liability under state law, Del Toro may include such risks in its self-insurance program and shall charge its costs of self-insuring such risks to the Account provided that such charges shall not exceed published statutory rates;

          9.3.11 All costs in excess of insurance proceeds necessary to repair or replace damage or losses to any of the Operating Assets, to the extent such damage or loss results from any cause other than the willful misconduct or gross negligence of Del Toro; provided that Del Toro shall furnish Bowerman with written notice of such damage(s) and/or loss(es) as soon as practicable after Del Toro has knowledge thereof;

          9.3.12 All legal and regulatory costs and expenses incurred in or resulting from operation of, recovery from, or which are necessary to protect, the Claims, including costs of title investigation and title curative services; provided that all attorneys’ fees and other legal costs to handle, investigate and settle litigation or claims, and amounts paid in settlement of such litigation or claims in excess of fifty thousand dollars ($50,000) per annum shall not be charged to the Account unless previously approved by Bowerman;

          9.3.13 All taxes, assessments and like charges on operation of the Claims and/or the Operating Assets which have been paid by Del Toro; provided, however, that each Party shall be separately responsible for taxes determined or measured by a Party’s sales revenue or net income;

          9.3.14 A monthly sum for each phase of operations as provided below, which shall be a liquidated amount to reimburse Del Toro for its office overhead and general and administrative expenses to conduct each phase of operations, and which shall be in lieu of any management fee or tax based on production of Products (the “Administrative Charges”): five hundred dollars ($500) per month for operations conducted under the 36-Month Work

          9.4.2 Except for conditions of force majeure and monetary payments owed to Bowerman, Del Toro or the SPE fails to perform a material obligation imposed upon it under this Agreement or the SPE’s operating agreement, and such failure continues for a period of sixty (60) days after Notice from Bowerman demanding performance;

          9.4.3 Del Toro or the SPE fails to pay or contest in good faith its bills and debts hereunder as such obligations become due;

     10.6 Continuing Authority. On termination of this Agreement under Sections 10.1, 10.2 or 10.3, or the deemed withdrawal of either Party pursuant to the provisions of this Agreement, Del Toro (or Bowerman if Del Toro withdraws) shall have the power and authority to do all things on behalf of both Parties which are reasonably necessary or convenient to (i) wind up operations, and (ii) 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 Party winding up operations 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 both Parties, encumber assets, and take any and every other reasonable action in any matter with respect to which the former Party continues to have, or appears or are alleged to have, a common interest or a common liability.

11. TRANSFER; PREEMPTIVE RIGHTS

     11.1 General. A Party shall have the right to Transfer to a third party an interest in its Participating Interest, including an interest in this Agreement, solely as provided for in this Section 11.

     11.2 Limitations on Free Transferability. Any Transfer by either Party under Section 11.1 shall be subject to the following limitations:

          11.2.1 Neither Party shall Transfer any interest in this Agreement (including any royalties, fees, profits, or other interest in the Products), except in conjunction with the Transfer of part or all of its Participating Interest;

          11.2.2 No transferee of all or any part of a Party’s Participating Interest shall have the rights of a Party unless and until the transferring Party has provided to the other Party Notice of the Transfer, and, except as provided in Sections 11.2.6 and 11.2.7, the transferee, as of the effective date of the Transfer, has committed in writing to assume and be bound by this Agreement to the same extent as the transferring Party;

           11.2.3 Neither Party shall make a Transfer that shall violate any Laws, or result in the cancellation of any permits, licenses, or other authorizations;

           11.2.4 No Transfer permitted by this Section 11 shall relieve the transferring Party of its share of any liability, whether accruing before or after such Transfer, that arises out of operations conducted prior to such Transfer or exists on the effective date of such Transfer;

          11.2.5 If a Transfer of less than all of a Participating Interest,

20

the transferring Party and its transferee shall act and be treated as one Party by notifying the non-transferring Party of their designated agent to act on their behalf with respect to all matters pertaining to this Agreement (provided that the transferring Party and its transferee may change the agent by giving Notice to the other Party, but such replacement must be one of them);

          11.2.6 If the Transfer results from the grant of an Encumbrance in a Participating Interest to secure a loan or other indebtedness of either Party in a bona fide transaction, such Encumbrance shall be granted only in connection with such Party’s financing payment or performance of that Party’s obligations under this Agreement and shall be subject to the terms of this Agreement and the rights and interests hereunder of the other Party. Any such Encumbrance shall be further subject to the condition that the holder of such Encumbrance (“Secured Party”) first enter into a written agreement with the other Party in form satisfactory to the other Party, acting reasonably, that binds the Secured Party, to the effect that (i) the Secured Party shall not enter into possession or institute any proceedings for foreclosure or partition of the encumbering Party’s Participating Interest and that such Encumbrance shall be subject to the provisions of this Agreement, (ii) the Secured Party’s remedies under the Encumbrance shall be limited to the sale of the whole (but only of the whole) of the encumbering Party’s Participating Interest to the other Party or, failing such a sale, at a public auction to be held at least ten (10) days after prior Notice to the other Party, such sale to be subject to the purchaser entering into a written agreement with the other Party (whereby such purchaser assumes all obligations of the encumbering Party under the terms of this Agreement); provided that the price of any preemptive sale to the other Party shall be the remaining principal amount of the loan plus accrued interest and related expenses, and such preemptive sale shall occur within sixty (60) days of the Secured Party’s Notice to the other Party of its intent to sell the encumbering Party’s Participating Interest. Failure of a sale to the other Party to close by the end of such period, unless failure is caused by the encumbering Party or by the Secured Party, shall permit the Secured Party to sell the encumbering Party’s Participating Interest at a public sale, and (iii) the charge shall be subordinate to any then-existing debt encumbering the transferring Party’s Participating Interest;

          11.2.7 If a sale or other commitment or disposition of Products or proceeds from the sale of Products by either Party upon distribution to it creates in a third party a security interest by Encumbrance in Products or proceeds therefrom prior to such distribution, such sale, commitment or disposition shall be subject to the terms and conditions of this Agreement.

     11.3 Preemptive Right. Any Transfer by either Party under Section 11.1 and any Transfer by an Affiliate of control of either Party shall be subject to a preemptive right of the other Party as described below.

          11.3.1 If either Party intends to Transfer all or any part of its

21

Participating Interest, or an Affiliate of either Party intends to Transfer control of such Party (“Transferring Entity”), such Party shall promptly notify the other Party of such intent. 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 the contract for sale. If the consideration for the intended transfer is, in whole or in part, other than monetary, the Notice shall describe such consideration and its monetary equivalent (based upon the fair market value of the non-monetary consideration and stated in terms of cash or currency).

          11.3.2 The other Party shall have ninety (90) days from the date such Notice is received to notify the Transferring Entity whether it elects to acquire the offered interest at the same price (or its monetary equivalent in cash or currency) and on the same terms and conditions as set forth in the Notice. If it does so elect, the acquisition by the other Party shall be consummated promptly after Notice of such election is delivered.

          11.3.3 If the other Party fails to exercise its priority right to purchase within the period provided for above, the Transferring Entity shall have one hundred eighty (180) days following the expiration of such period to consummate the Transfer to the third party at a price and on terms no less favorable to the Transferring Entity than those offered. If the Transferring Entity fails to consummate the Transfer to a third party within the period set forth above, the other Party’s preemptive right 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 subsection.

          11.3.4 These procedures shall not apply to the (i) Transfer by either Party of all or any part of its Participating Interest to an Affiliate; pursuant to an incorporation, or corporate or company consolidation or reorganization of a Party by which the surviving entity shall possess substantially all of the stock or all of the property rights and interests, and be subject to substantially all of the liabilities and obligations of that Party; or corporate or company merger or amalgamation by which the surviving entity or amalgamated company shall possess all of the stock or all of the property rights and interests, and be subject to substantially all of the liabilities and obligations of that Party, (ii) subject to Subsection 11.2.6 of this Agreement, the grant by either Party of a security interest in its Participating Interest by Encumbrance, (iii) the creation by any Affiliate of either Party of an Encumbrance affecting its Control of such Party, (iv) a sale or other commitment or disposition of Products or proceeds from sale of Products by either Party upon distribution to it pursuant to this Agreement, or (v) failure of a Party’s Affiliate to comply with this Section 11, which shall be a breach by such Party of this Agreement.

12. DISPUTES

     12.4 Fees and Costs. All disputes arising under or in connection with this Agreement that cannot be resolved by agreement between the Parties shall be resolved in accordance with applicable Laws.

     13.2 Party Information. In performing its obligations under this Agreement, neither Party shall be obligated to disclose any its Party Information to the other Party.

23

may be). Each Party may use and enjoy the benefits of either Party’s disclosed Party Information and Enhancements thereto in the conduct of its performance hereunder, but the Party that did not originally develop, conceive, originate or obtain such Party Information may not use such Party Information or Enhancements thereto for any other purpose. Except as provided in Section 13.4, or with the prior written consent of the other Party, which consent may be withheld in such Party’s sole discretion, each Party shall keep confidential and not disclose to any third party or the public any portion of any of the other Party’s Party Information or Enhancements thereto that constitute Confidential Information.

     13.3 Permitted Disclosure of Confidential Business Information. Either Party may disclose Business Information that is Confidential Information (i) to a Party’s managers, members, officers, directors, partners, employees, Affiliates, shareholders, agents, attorneys, accountants, consultants, contractors, subcontractors or advisors, for the sole purpose of such Party’s performance of its obligations under this Agreement, (ii) to any bona fide potential transferee to whom the disclosing Party contemplates a Transfer of all or any part of its Participating Interest, for the sole purpose of evaluating the proposed Transfer, (iii) to any actual or potential lender, underwriter or investor for the sole purpose of evaluating whether to make a loan to or investment in the disclosing Party, or (iv) to a third party with whom the disclosing Party contemplates any independent business activity or operation. The Party disclosing Confidential Information pursuant to this Section 13.3, shall disclose such Confidential Information only to those parties who have a bona fide need to have access to such Confidential Information for the purpose for which disclosure to such parties is permitted under this Section 13.3 and who have agreed in writing supplied to, and enforceable by, the other Party to protect the Confidential Information from further disclosure, to use such Confidential Information solely for such purpose and otherwise to be bound by the provisions of this Section 13. Such writing shall not preclude parties described in Section 13.3(ii) from discussing and completing a Transfer with the other Party. The Party disclosing Confidential Information shall be responsible and liable for any use or disclosure of the Confidential Information by such parties in violation of this Agreement and such other writing.

     13.4 Disclosure Required By Law. Notwithstanding anything to the contrary contained in this Section 13, a Party may disclose any Confidential Information if, in the opinion of the disclosing Party’s legal counsel, (i) such disclosure is legally required to be made in a judicial, administrative or governmental proceeding pursuant to a valid subpoena or other applicable order, or (ii) such disclosure is legally required pursuant to the rules or regulations of a stock exchange or similar trading market applicable to the disclosing Party. Prior to any disclosure of Confidential Information under this Section 13.4, the disclosing Party shall give the other Party at least ten (10) days of prior Notice (unless another time period is required by such rules, regulations or proceeding)

24

and, in making such disclosure, the disclosing Party shall disclose only that portion of Confidential Information required to be disclosed and shall take all reasonable steps to preserve the confidentiality thereof, including obtaining protective orders and supporting the other Party’s intervention in any such proceeding.

     13.5 Public Announcements. Prior to making or issuing any press release or other public announcement or disclosure of Business Information that is not Confidential Information, a Party shall first consult with the other Party as to the content and timing of such announcement or disclosure, unless in the good faith judgment of such Party, there is not sufficient time to consult with the other Party before such announcement or disclosure must be made under applicable Laws; but in such event, the disclosing Party shall notify the other Party, as soon as possible, of the pendency of such announcement or disclosure, and it shall notify the other Party before such announcement or disclosure is made if at all reasonably possible. Any press release or other public announcement or disclosure to be issued by either Party relating to this Business shall also identify the other Party.

14. INDEMNIFICATION

     14.1 Indemnities / Limitation of Liability. Each Party shall indemnify, defend and hold harmless the other Party, its managers, members, directors, officers, employees, agents and attorneys-in-fact, or Affiliates (collectively, “Indemnified Party”) from and against the entire amount of any Material Loss. A “Material Loss” means all costs, expenses, damages, fines, penalties or liabilities, including attorneys’ fees and other costs of litigation (either threatened or pending) arising out of or based on a breach by a Party (“Indemnifying Party”) of any representation, warranty or covenant contained in this Agreement. A Material Loss shall not be deemed to have occurred until, in the aggregate, an Indemnified Party incurs losses, costs, damages or liabilities in excess of ten thousand dollars ($10,000) (the “Indemnification Threshold”) relating to breaches of warranties, representations and covenants contained in this Agreement. Once the Indemnification Threshold is reached, the Indemnifying Party shall be liable for the entire amount of the Material Loss.

     14.2 Indemnification Procedure. If any claim or demand is asserted against an Indemnified Party in respect of which such Indemnified Party may be entitled to indemnification under this Agreement, written Notice of such claim or demand shall promptly be given to the Indemnifying Party. The Indemnifying Party shall have the right, but not the obligation, by notifying the Indemnified Party within thirty (30) days after its receipt of the Notice of the claim or demand, to assume the entire control of (subject to the right of the Indemnified Party to participate, at the Indemnified Party’s expense and with counsel of the Indemnified Party’s choice), the defense, compromise, or settlement of the matter, including, at the Indemnifying Party’s expense, employment of counsel of

25

the Indemnifying Party’s choice. Any damages to the assets or business of the Indemnified Party caused by a failure by the Indemnifying Party to defend, compromise, or settle a claim or demand in a reasonable and expeditious manner requested by the Indemnified Party, after the Indemnifying Party has given Notice that it will assume control of the defense, compromise, or settlement of the matter, shall be included in the damages for which the Indemnifying Party shall be obligated to indemnify the Indemnified Party. Any settlement or compromise of a matter by the Indemnifying Party shall include a full release of claims against the Indemnified Party that have arisen out of the indemnified claim or demand.

     15.6 Modification. No change, amendment or other modification of this Agreement shall be valid unless made in writing and duly executed by both Parties.

     15.7 Force Majeure. Except for the obligation to make payments when

     15.12 Counterparts. This Agreement may be executed in any number of counterparts, and it shall not be necessary that the signatures of both Parties be contained on any counterpart.
