Please find enclosed herewith for your review an Option Agreement (the "Option Agreement") prepared with respect to the Dixie Lake Property located in the Red Lake Mining Division Ontario.

You will note that in the interests of expediency the Option Agreement does not attach a form of joint venture agreement however Article 8 of the Option Agreement does contain the major terms which will form the basis of any joint venture agreement to be entered into. More specifically, Article 8 considers, among other things:

Please also note that the term 'Joint Venture Agreement' is defined in the Option Agreement to mean "the joint venture agreement to be negotiated and entered into by the parties in good faith and on commercially reasonable terms (including those terms contained in this Agreement)". As such, the terms contained in the Option Agreement will form part of the Joint Venture Agreement.

Finally, we would ask that you note subsection 8.02(e) wherein it is indicated that if either Grandview or Fronteer's participating interest falls below ten percent (10%) then any such party's interest will be converted into a ten percent (10%) net profit royalty. We expect that a definition of such term would be set out in full in the Joint Venture Agreement, however, if you prefer we can set same out in the Option Agreement and would ask that you send us a form of net profit royalty which is acceptable to you for our review.

Should you have any questions about the Agreement, please do not hesitate to contact us.

Upon Grandview incurring or causing to be incurred, the Expenditures referred to in Section 4.02, in the time contemplated thereby, and having exercised the Option, Grandview shall be vested with a 51% undivided interest in the Property pursuant to Section 6.01 as of the date (the “Vesting Date”) on which Grandview incurred the Expenditures referred to in Section 4.02 and Grandview and Fronteer shall have formed a joint venture and shall be be deemed to have associated themselves into a joint venture on the terms and conditions contained in the Joint Venture Agreement to be negotiated and entered into in good faith and on commercially reasonable terms (including those terms contained in this Agreement) by the parties including the following:

(a) Each of Grandview and Fronteer may elect to contribute to the Program and Budget in some lesser amount than their respective participating interest, or not to contribute at all. Each of Grandview and Fronteer shall have the right to elect to participate or not to participate without regard to its vote on the adoption of the Program and Budget. The participating interest of such diluting participant ( the "Diluting Participant") will be reduced effective as of the date the Program and 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:

If the reducing party has the right to redeem its position as set out herein and wishes to exercise said right then the reducing party shall inform the other party prior to the said meeting of the management committee. A party redeeming its participating interest shall pay the costs it would have paid had it participated to the fullest extent possible in the Program and Budget, plus interest thereon from the date of any expenditure to the date of payment at an annual rate equal to the Prime Rate plus 2%. Payment shall be made by the redeeming party to the other part for the amount which the other party contributed to the Program and Budget, within 30 days of receipt from the other party of an invoice for its share; and

(e) If either party's participating interest falls below 10%, then that party's interest will automatically and instantaneously be converted into a 10% net profit royalty. [Schedule "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 party with respect to this Agreement and the other party, and it shall comply with and be bound by the terms and conditions of this Agreement.

Except as otherwise provided in Section 9.04, if either party (the “Selling Party”) desires to Transfer all or any part of its Interest, the other party (the “Remaining Party”) shall have a pre-emptive right to acquire such Interest as provided in this Section 9.03:

(a) if the Selling Party intends to Transfer all of its Interest, it shall promptly notify the Remaining Party 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. 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 stated in terms of cash or currency, together with information sufficient to establish the basis for such equivalence. The Remaining Party shall have 30 days from the date such notice is delivered to notify the Selling Party whether it elects to acquire the offered interest for the same consideration or its monetary equivalent in cash or currency, and on the same terms and conditions as set forth in the notice. If the Remaining Party so elects, the Transfer shall be consummated promptly after notice of such election is delivered to the Selling Party;

(b) if the Remaining Party does not so elect within the period provided for in Section 9.03(a), the Selling Party shall have 90 days following the expiration of such period to consummate the Transfer to a third party for the consideration and on terms no less favourable than those offered by it to the Remaining Party in the notice required in Section 9.03(a); and

(c) if the Selling Party fails to consummate the Transfer to a third party within the period set forth in Section 9.03(b), the pre-emptive right of the Remaining Party 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 9.03.

(b) corporate consolidation, merger, amalgamation or reorganization of or by any 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 the party;

(c) the grant by any party of a security interest in its Interest by mortgage, deed of trust, pledge, lien or other encumbrance and any Transfer of such interest by reasons of exercise of the rights granted to the secured party;

(d) the grant by the parties of an option to a third party as contemplated by Article 11 hereof.

The financial terms of this Agreement and all information obtained in connection with the performance of this Agreement shall be the exclusive property of the parties and, except as provided in Section 10.02, shall not be disclosed by Fronteer or Grandview to any third party or the public without the prior written consent of the other party, which consent shall not be unreasonably withheld. Whenever practical, any announcements, press releases, or public statements shall be issued jointly by the parties.

Unless required by law or regulatory authority, if a party is identified in such public announcement or statement it shall not be released without the consent of such party. As to any disclosure pursuant to Section 10.02(a) or 10.02(b), only such confidential information as such third party shall have a legitimate business need to know shall be disclosed and such third party shall first agree in writing to protect the confidential information from further disclosure to the same extent as the parties are obligated under this Article 10.

Nothing contained in this Agreement shall be deemed to constitute either party, the partner of the other, nor, except as otherwise herein expressly provided, to constitute either party the agent or legal representative of the other, nor to create any fiduciary relationship between them. It is not the intention of the parties to create, nor shall this Agreement be construed to create, any mining, commercial or other partnership. Neither of the parties shall have any authority to act for or to assume any obligation or responsibility on behalf of the other, except as otherwise expressly provided herein. The rights, duties, obligations and liabilities of the parties shall be several and not joint or collective. 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, it being the express purpose and intention of the parties that their ownership of Assets and rights acquired hereunder shall be as tenants-in-common.
