RIGHT TO ENTER AND DO WORK/MANAGEMENT COMMITTEE/BUDGETS

6.1 Rights of Operator

Subject to the provisions of this Agreement, Northwestern shall, so long as Northwestern has not exercised its Option under section 2.8 and Minera Tango, Northwestern and the Mining Company have not yet entered into the Shareholders’ Agreement, be the Operator of the Concessions and their corresponding mining lots through NMS and, subject to the right of Minera Tango to enter in, under or upon the mining lots covered by the Concessions in accordance with the terms of this Agreement and subject to the provisions of the concessions that comprise the Concessions, any Applicable Laws and the rights of any Government Agency, shall have the sole and exclusive right:

(i) to enter in, under or upon the mining lots covered by the Concessions;

(ii) to have possession of the mining lots covered by the Concessions;

(iii) to carry out such Work as Northwestern in its sole discretion considers advisable including bringing or erecting upon the mining lots covered by the Concessions machinery, equipment and ancillary facilities including, without limiting the generality of the foregoing, housing, utility services, roads, conveyors, plants, buildings, waste areas, tailing areas and disposal areas or systems;

(iv) obtain and maintain in the name of Minera Tango all concessions, licences, permits and authorizations required to carry out the Work; and

-20-

(v) to remove Ore, minerals or metals from the mining lots covered by the Concessions in such reasonable quantities for the purpose of obtaining assays or making other tests. Any income derived from the sale of such Ore, minerals or metals removed from the mining lots covered by the Concessions in accordance with the foregoing shall be applied by the Operator to Work Costs but not applied to the $3,000,000 of Work Costs to be incurred by Northwestern directly or through NMS in order to exercise the Option.

6.2 Maintenance of Concessions

During the Option Period, Northwestern shall take all measures required to maintain the Concessions in good standing with all Government Agencies and under all Applicable Laws, except any Dropped Concessions, which shall be dealt with in accordance with section 2.11. During the Option Period, Northwestern shall, in a timely manner, fund in accordance with section 6.3 all Work Costs and carry out all acts required to maintain the Concessions in good standing with all Government Agencies and under all Applicable Laws, including, without limitation, the payment of any and all Maintenance Costs. Northwestern shall fund and pay the Maintenance Costs directly or indirectly until:

(a) Northwestern or NMS has exercised the Option, or

(b) the Option expires or is terminated without having been exercised by Northwestern or NMS;

whichever occurs first. If the Option expires or is terminated without having been exercised by Northwestern, either directly or through NMS, Minera Tango shall be responsible for, and pay and fund all Maintenance Costs from and after the date of such expiration or termination. Where Northwestern, directly or indirectly, has exercised the Option, the Mining Company shall be responsible for and pay all Maintenance Costs from and after the Earn-In Date. For greater certainty, Northwestern’s obligation to pay Maintenance Costs applies only to Maintenance Costs, the liability for which did not arise prior to the Effective Date.

6.3 Maintenance Costs Budget

Minera Tango shall provide Northwestern with an annual budget and timetable for expending and performing the Maintenance Costs (the “Annual Budget”) within 45 days of the Effective Date and shall provide Northwestern with an Annual Budget within 45 days of each anniversary date of the Effective Date.

No later than thirty (30) days after the Effective Date, Northwestern shall deliver to Minera Tango a written program and budget specifying in reasonable detail an outline, including the estimated Work Costs together with an activities schedule and timetable, of any and all research, prospecting, exploration and development proposed to be carried out during the first phase of the exploration program Northwestern proposes to carry out on the mining lots covered by the

-21-

Concessions, which shall be in the sole discretion of Northwestern. Within sixty (60) days of completion of such program and budget and each subsequent phase of the exploration program, Northwestern will prepare and provide Minera Tango with a program and budget for the next phase of the program. Northwestern will give detailed advance notice in writing to Minera Tango of any material deviation from any program and budget, together with the reasons therefore and a revised program and budget for the remaining months of the applicable Work Costs period.

6.5 Informal Advisory Committee

During the Option Period, an informal committee consisting of Northwestern and Minera Tango management and technical personnel shall meet on at least a semi-annual basis or on such shorter basis as mutually deemed necessary by Northwestern and Minera Tango to address matters relating to Work to be conducted by Northwestern through NMS as Operator pursuant to this Agreement. Northwestern shall take into account in good faith any technical and managerial comments made by the representatives of Minera Tango, but shall continue to have sole discretion regarding all Work Costs incurred.

6.6 Conduct of Work

All Work conducted by Northwestern through NMS or its Agents on the mining lots covered by the Concessions shall be done in a prudent and workmanlike manner to the best of its ability, skill and judgment and in accordance with good mining practice and in compliance with all Applicable Laws, and in accordance with the terms of the applicable concessions, licences, permits and agreements pertaining to the Concessions. Northwestern shall promptly notify Minera Tango of any allegations of violation of any of the foregoing.

6.7 Insurance

During the Option Period, Northwestern through NMS as Operator shall acquire and maintain adequate insurance coverage in accordance with normal industry standards and practice protecting the interests of Minera Tango (including from third party claims) and shall cause its Agents to obtain and maintain similar adequate insurance. For greater certainty and without limitation, such insurance shall include public liability and property damage coverage in accordance with normal industry standards naming Minera Tango as an insured, with severability of interest and protecting the interests of Minera Tango (including from third party claims).

During the Option Period, Northwestern through NMS as Operator shall pay or cause to be paid all Agents of Northwestern including, without limitation, workers or wage earners employed by Northwestern through NMS on the mining lots covered by the Concessions and for all material purchased by Northwestern in connection with all Work which might give rise to a lien or privilege on the mining lots covered by the Concessions. Should any such lien or privilege be recorded against the Concessions in consequence of any Work done on the mining lots covered by the Concessions by or for Northwestern through NMS, Northwestern through NMS shall forthwith take all such actions, including initiating legal proceedings, as may be necessary to

-22-

have such lien or privilege removed or discharged from the Concessions and shall have the same removed or discharged with all reasonable dispatch provided, however, that upon such removal or discharge of such lien or privilege, Northwestern or NMS may proceed to contest any such claim of lien or privilege in good faith and diligently.

SCHEDULE “E”

RULES FOR ARBITRATION

The following rules and procedures shall apply with respect to any matter to be arbitrated by the Parties under the terms of the Agreement.

1. INITIATION OF ARBITRATION PROCEEDINGS

(a) If any Party wishes to have any matter under this Agreement arbitrated in accordance with the provisions of this Agreement, it shall give notice to the other Party specifying particulars of the matter or matters in dispute and proposing the name of the person it wishes to be the single arbitrator. Within 5 days after receipt of such notice, the other Party shall give return notice to the first Party advising whether such Party accepts the arbitrator proposed by the first Party and if such Party does not accept the arbitrator proposed by the first Party, proposing the name of the person it wishes to be the single arbitrator. If such return notice is not received by the first Party within such 5 day period, the other Party shall be deemed to have accepted the arbitrator proposed by the first Party. If such return notice is received by the first Party within such 5 day period and the other Party does not accept the proposed arbitrator of the first Party and proposes another person to be arbitrator, the first Party shall, within 5 days after receipt of such return notice, give notice to the other Party advising whether such first Party accepts the arbitrator proposed by the other Party. If the Parties do not agree upon a single arbitrator within such second 5 day period, the single arbitrator shall be chosen in accordance with the Arbitration Act, 1991 (Ontario).

(b) The individual selected as Arbitrator shall be qualified by education and experience to decide the matter in dispute. The Arbitrator shall be at arm’s length from both Parties and shall not be a member of the audit or legal firm or firms who advise either Party, nor shall the Arbitrator be a person who is otherwise regularly retained by either of the Parties.

2. SUBMISSION OF WRITTEN STATEMENTS

(a) Within 5 days of the appointment of the Arbitrator, the Party initiating the arbitration (the “Claimant”) shall send the other party (the “Respondent”) a statement of claim setting out in sufficient detail the facts and any contentions of law on which it relies, and the relief that it claims.

(b) Within 10 days of the receipt of the statement of claim, the Respondent shall send the Claimant a statement of defence stating in sufficient detail which of the facts and contentions of law in the statement of claim it admits or denies, on what grounds, and on what other facts and contentions of law he relies.

(c) Within 5 days of receipt of the statement of defence, the Claimant may send the Respondent a statement of reply.

-2-

(d) All statements of claim, defence and reply shall be accompanied by copies (or, if they are especially voluminous, lists) of all essential documents on which the party concerned relies and which have not previously been submitted by any party, and (where practicable) by any relevant samples.

(e) After submission of all the statements, the Arbitrator will give directions for the further conduct of the arbitration.

3. MEETINGS AND HEARINGS

(a) The arbitration shall take place in the City of Toronto, Ontario, Canada or in such other place as the Claimant and the Respondent shall agree upon in writing. The arbitration shall be conducted in English unless otherwise agreed by such parties and the Arbitrator. Subject to any adjournments which the Arbitrator allows, the final hearing will be continued on successive working days until it is concluded.

(b) All meetings and hearings will be in private unless the Parties otherwise agree.

(c) Each Party may be represented at any meetings or hearings by legal counsel.

(d) Each Party may examine, cross-examine and re-examine all witnesses at the arbitration.

4. THE DECISION

(a) The Arbitrator will make a decision in writing and, unless the Parties otherwise agree, will set out reasons for decision in the decision.

(b) The Arbitrator will send the decision to the Parties as soon as practicable after the conclusion of the final hearing, but in any event no later than 30 days thereafter, unless that time period is extended for a fixed period by the Arbitrator on written notice to each Party because of illness or other cause beyond the Arbitrator’s control.

(c) The decision shall determine and award costs to the successful Party in the arbitration.

(d) The decision shall be final and binding on the Parties and shall not be subject to any appeal or review procedure provided that the Arbitrator has followed the rules provided herein in good faith and has proceeded in accordance with the principles of natural justice. In the event either Party initiates any court proceeding in respect of the decision of the Arbitration or the matter arbitrated, such Party shall, if unsuccessful in the court proceeding, shall pay the other Party’s costs on a solicitor/client basis plus all other reasonable expenses incurred by such other Party from the date of delivery of the notice commencing arbitration to the date of determination of such court proceeding.

5. JURISDICTION AND POWERS OF THE ARBITRATOR

(a) By submitting to arbitration under these Rules, the Parties shall be taken to have conferred on the Arbitrator the following jurisdiction and powers, to be exercised at the Arbitrator’s discretion subject only to these Rules and the relevant law with the object of ensuring the just, expeditious, economical and final determination of the dispute referred to arbitration.

(b) Without limiting the jurisdiction of the Arbitrator at law, the Parties agree that the Arbitrator shall have jurisdiction to:

(i) determine any question of law arising in the arbitration;

(ii) determine any question as to the Arbitrator’s jurisdiction;

(iii) determine any question of good faith, dishonesty or fraud arising in the dispute;

(iv) order any Party to furnish further details of that Party’s case, in fact or in law;

(v) proceed in the arbitration notwithstanding the failure or refusal of any Party to comply with these Rules or with the Arbitrator’s orders or directions, or to attend any meeting or hearing, but only after giving that Party written notice that the Arbitrator intends to do so;

(vi) receive and take into account such written or oral evidence tendered by the Parties as the Arbitrator determines is relevant, whether or not strictly admissible in law;

(vii) make one or more interim awards;

(viii) hold meetings and hearings, and make a decision (including a final decision) in Toronto, Ontario, Canada or elsewhere with the concurrence of the Parties thereto;

(ix) order the Parties to produce to the Arbitrator, and to each other for inspection, and to supply copies of, any documents or other evidence or classes of documents in their possession or power which the Arbitrator determines to be relevant; and

(x) make interim orders to secure all or part of any amount in dispute in the arbitration.
