DE C.V., a corporation having an address for notice and delivery located at Plaza Agua Caliente Blvd. Agua Caliente 4558-1201 Tijuana, B.C. 22420, Mexico ("Seville"); OF THE SECOND PART AND: MINERA CORTEZ RESOURCES LTD., a corporation having an address for notice and delivery at 5640 Marine Drive, West Vancouver, British Columbia, V7W 2R6 ("Minera Cortez"); OF THE THIRD PART -- Right of First Refusal Agreement -- -- Azco Mining Inc. -- 3 -2- (Seville and Minera Cortez being hereinafter collectively referred to as "Minera" as the context so requires); and (Azco and Minera being hereinafter singularly also referred to as a "Party" and collectively referred to as the "Parties" as the context so requires). WHEREAS IN CONSIDERATION of the mutual covenants contained in, and the mutual benefits to be derived from, this Agreement, and including, without limiting the generality of the foregoing, the subscription by Azco for 200,000 common shares of Mineral Cortez at a subscription price of $0.25 per common share, the Parties hereto agree as follows: ARTICLE I RIGHT OF FIRST REFUSAL - PROPERTY INTERESTS 1.1 RESTRICTION AND ASSIGNMENT RESPECTING PROPERTY INTERESTS. During the subsistence of this Agreement, which shall be for a period of five years from the above-referenced Effective Date of this Agreement (the "Option Period"), Minera may not joint venture, option, sell, transfer or otherwise dispose of all or any part of its present or hereinafter acquired interest in and to any resource property interest (each being a "Property Interest") except in accordance with the terms of this Agreement; provided, however, that Minera may at any time at its sole discretion and without the prior approval of Azco assign and transfer a Property Interest to any of its wholly owned subsidiaries, if any, subject at all times to the requirement that any such subsidiary remain wholly owned by Minera failing which any such interest must be immediately transferred back to Minera; and provided further that any transfer of all or any part of Minera's Property Interests or interests under this Agreement to its wholly owned subsidiary shall be accompanied by the written agreement of any such subsidiary to assume the obligations of Minera hereunder and to be bound by the terms and conditions hereof. 1.2 RIGHT OF FIRST REFUSAL ON ANY OFFERED PROPERTY INTERESTS. Minera hereby grants to Azco a 60 calendar day right of first refusal during the Option Period to acquire all, but not less than all, of any Property Interest which Minera desires to either joint venture, option or dispose of in any manner during the Option Period (each being an "Offered Property Interest"). 1.3 BONA FIDE OFFER. If Minera receives a bona fide offer (an "Offer") to either joint venture, option or sell any Offered Property Interest, then Minera shall forthwith offer the Offered Property Interest to Azco. The offer to Azco shall be on terms and conditions substantially identical to, and of pro rata equivalent dollar value as, those contained in the Offer either to or from the third party. -- Right of First Refusal Agreement -- -- Azco Mining Inc. -- 4 -3- 1.4 ELECTION. Azco shall be entitled to elect, by notice in writing (the "Notice") to Minera within 60 calendar days from the date of receipt by Azco of the Offer, to accept the Offered Property Interest on terms and conditions substantially identical to those contained in the Offer either to or from the third party (collectively, the "Terms and Conditions"). If Azco fails to provide the Notice within the time required, Azco shall be deemed to have declined to exercise its right of first refusal in connection with that particular Offer. 1.5 CONSIDERATION. Subject to Article "III" hereinbelow, in the event that Azco elects, pursuant to section "1.4" hereinabove, to accept an Offered Property Interest then, notwithstanding the remaining Terms and Conditions, and in order that Azco may accept the Offered Property Interest on terms substantially identical with the proposed consideration terms under the original Offer, Azco will be entitled to match the proposed consideration terms under any such Offer by way of the equivalent combination of both issuing shares of Azco (collectively, the "Shares") and paying cash consideration (the "Cash Consideration") to Minera such that the value of any such Shares and/or Cash Consideration, as the case may be, will be equivalent in value to the proposed consideration terms under the Offer and in the substantially identical relative share/cash proportions. In this regard, and in order to more particularly determine the value of any Shares to be provided by Azco for its acceptance of an Offered Property Interest, Azco shall be entitled to utilize the previous ten-day average closing price of Azco's common shares on The Toronto Stock Exchange as at the date of any Notice as the appropriate per Share price forming part of any such Share consideration. For greater certainty it is hereby acknowledged and agreed that any proposed consideration under the terms of an Offer which contemplates either cash consideration and/or work commitment expenditures or the like must be matched by Azco in the Terms and Conditions of its Notice. 1.6 NOT EXERCISED. If Azco does not exercise its right to accept an Offered Property Interest as aforesaid, Minera may, for a period of 180 calendar days following the last date upon which Azco could have made the election pursuant to section "1.4" hereinabove, dispose of the Offered Property Interest but only on terms and conditions substantially identical to those as contained in the Offer for that Offered Property Interest. 1.7 TERMINATION OF RIGHT OF FIRST REFUSAL. Except with respect to the specified Offered Property Interest, the right of first refusal to acquire up to 100% of any Offered Property Interest will not terminate if, on receipt of any Offer from Minera under this section, Azco fails to exercise the right. 1.8 EXCLUSIONS TO RIGHT OF FIRST REFUSAL. The right of first refusal shall not apply to any sales or transfers of Property Interests from Seville to Minera Cortez. In addition, it shall be subordinated to any such right granted by Minera Cortez in any joint venture, option or property purchase to an optionor or vendor of any Property Interests acquired by Mineral Cortez subsequent to the Effective Date hereof. -- Right of First Refusal Agreement -- -- Azco Mining Inc. -- 5 -4- ARTICLE II RIGHT OF FIRST REFUSAL - FINANCINGS FOR MINERA CORTEZ 2.1 NOTIFICATION. Minera Cortez will notify Azco of the terms of any further private and/or public equity or debt financing that it requires or proposes to obtain during the Option Period (each a "Financing") and Azco will have the right of first refusal to provide up to 100% of any such Financing on terms and timing substantially identical as any third party is prepared to provide. 2.2 EXERCISE OF RIGHT. This right of first refusal must be exercised by Azco within 7 calendar days following its receipt of the notice from Mineral Cortez offering terms of Financing, or advising that it is prepared to accept a third party offer of Financing, by notifying Minera Cortez that they will provide up to 100% of such Financing on terms substantially identical to those contained in the notice. 2.3 FAILURE TO GIVE NOTICE. If Azco fails to give notice within the 7 calendar days that it will provide up to 100% of such Financing upon the terms set out in the notice, Minera Cortez will then be free for 180 calendar days to make other arrangements to obtain financing from another source on substantially identical terms. 2.4 TERMINATION OF RIGHT OF FIRST REFUSAL. The right of first refusal to provide Financing will not terminate if, generally, on receipt of any notice from Minera Cortez under this section, Azco fails to exercise the right for that Financing. 2.5 EXCLUSIONS TO RIGHT OF FIRST REFUSAL. For greater certainty the right of first refusal to provide Financing hereunder shall not apply to any securities issued by Minera Cortez for incentive stock options, to vendors or optionors for properties, pursuant to any amalgamation or reorganization or pursuant to its initial public offering of securities (unless Minera Cortez will thereupon have adequate share distribution for listing). In addition, the right of first refusal to provide Financing shall not apply to Seville. ARTICLE III ARBITRATION 3.1 MATTERS FOR ARBITRATION. Notwithstanding section "1.5" hereinabove, the Parties hereto agree that all questions or matters in dispute with respect to this Agreement shall be submitted to binding arbitration pursuant to the terms hereof. 3.2 NOTICE AND NEGOTIATION. It shall be a condition precedent to the right of any Party to submit any matter to arbitration pursuant to the provisions hereof that such -- Right of First Refusal Agreement -- -- Azco Mining Inc. -- 6 -5- Party intending to refer any matter to arbitration shall have given to the other Party, not less than 10 calendar days' prior written notice of its intention to do so, together with reasonable particulars of the matter in dispute, and that such complaining Party shall have invited the noticed Party at least once to negotiate the dispute. On the expiration of such 10 calendar days the Party who gave such notice may proceed to refer the dispute to arbitration as provided for in section "3.3" hereinbelow. 3.3 APPOINTMENTS AND PROCEDURE. After the 10 calendar day period set forth in section "3.2" hereinabove a Party desiring arbitration shall appoint one arbitrator with a statement of credentials and shall notify the noticed Party of such appointment, and the noticed Party shall, within 10 calendar days after receiving such notice, agree that such first arbitrator shall be the only arbitrator or shall appoint a second arbitrator and give notice of the same. The two arbitrators so named, before proceeding to act, shall, within 10 calendar days of the appointment of the last appointed arbitrator, agree on the appointment of a third arbitrator to act with them, and such three arbitrators shall select a chairman from themselves. If the noticed Party shall fail to appoint and give notice of an arbitrator within 10 calendar days after receiving notice of the appointment of the first arbitrator, then the first arbitrator shall act as a single arbitrator, and if the two arbitrators appointed by the Parties shall be unable to agree on the appointment of a third, then the third arbitrator shall be appointed under the provisions (the "Rules") of the Commercial Arbitration Act (British Columbia) or, failing that, by a judge of the Supreme Court of the Province of British Columbia on the motion of any Party to the dispute. Except as specifically otherwise provided in this section, the arbitration herein provided for shall be conducted in accordance with such Rules. Where there is an insufficiency in this Article or the Rules then the arbitrators shall make reference to the provisions of the procedures and practices of the British Columbia International Commercial Arbitration Centre (Domestic Arbitration) and, if there is further insufficiency, and otherwise in interpretation and rulings regarding this Article or the Rules and regarding the matters of dispute, the arbitrators shall be the masters of procedure, evidence, rules of order and the process of law and judgment. Where this Agreement, the constating documents of either Party, other documents relevant to the Parties or the law does not provide for or address any material matter in dispute, then the arbitrator(s) shall have reference to the customary practice of the industry and, if the Parties do not call expert testimony, the arbitrator(s) may, but is not obliged to, call its own determined expert testimony at the cost of the Parties. The arbitrators, or in the case where only one arbitrator is appointed, the single arbitrator, shall fix a time and place in accordance with agreement of the Parties or the Rules and shall establish the calendar and procedure for the purpose of hearing the evidence and representations of the Parties. When Azco is not a party to the arbitration the Parties and the arbitrator(s) shall copy Azco with all correspondence and submissions to or from the arbitrator(s) (omission to do so shall not invalidate the proceedings) unless the arbitrator(s) rules that any communication is privileged, or any rulings or awards. Azco shall have the right to intervene in the arbitration and have standing to make representations on such terms as to costs as the arbitrator(s) may determine. Any arbitration shall be transcribed, unless the Parties waive such, and the proceedings and hearings and decisions shall be confidential and in closed hearings unless the Parties waive such, partly or wholly or as may be necessary for any execution of an arbitration award. After hearing any evidence and representations that the Parties may submit, the single arbitrator, or the arbitrators, as the case may be, shall make an award and reduce the same to writing, and deliver one copy thereof to each of the Parties. The expense of the arbitration shall be paid as specified in the award but, failing specification, each Party -- Right of First Refusal Agreement -- -- Azco Mining Inc. -- 7 -6- shall bear its own costs and the losing party shall bear the cost of the arbitrator(s) and the arbitration facilities. 3.4 AWARD. The Parties agree that the award of a majority of the arbitrators, or in the case of a single arbitrator, of such arbitrator, shall be final, binding and enforceable upon each of them and shall not be appealable except for manifest error of law. ARTICLE IV GENERAL 4.1 ENTIRE AGREEMENT.
