Dear Mr. O'Dea:

National Bank Financial Inc. ("NBF"), Canaccord Capital Corporation, Pacific International Securities Inc. and Sprott Securities Limited (each, an "Underwriter", and collectively the "Underwriters") hereby severally, in respect of the percentages set forth in section 6.1 of this Agreement, and not jointly, offer to purchase from Fronteer Development Group Inc. (the "Corporation") upon and subject to the terms hereof, an aggregate of 6,000,000 common shares of the Corporation (each a "Share") at a price of $6.40 per Share (the "Offering Price"). The offering of the Shares by the Corporation described in this Agreement is hereinafter referred to as the "Offering".

The net proceeds of the Offering shall be used by the Corporation to fund (a) future acquisitions, (b) ongoing exploration at the Wernecke properties in the Yukon Territory (primarily to continue staking, field mapping and sampling of target areas and completion of an airborne gravity survey), (c) ongoing exploration at the Biga properties in Turkey, (d) ongoing exploration at the San Pedro and Clara properties in Mexico (primarily to conduct drill programs), and (e) general corporate purposes.

The Underwriters and the Corporation acknowledge that the schedules hereto form part of this Agreement.

In consideration of the Underwriters' services to be rendered in connection with the Offering, the Corporation shall pay to NBF, for and on behalf of all of the Underwriters, a cash fee (the "Underwriters' Fee") in an amount equal to 5.5% of the gross proceeds received by the Corporation from the issue and sale of the Shares.

The Offering shall take place in the Qualifying Jurisdictions (as hereinafter defined) and in the United States, provided however that offers and sales of Shares in the United States shall be made only on a private placement basis in accordance with United States securities laws and the provisions of Schedule "A" to this Agreement.

To the extent that U.S. Substituted Purchasers purchase Shares on the Closing Date, the obligations of the Underwriters to do so shall be reduced by the number of Shares purchased from the Corporation by such U.S. Substituted Purchasers.

	(a)	any breach by the Corporation of, or default under, any covenant or agreement of the Corporation in this Agreement which has not been waived by the Underwriters under this Agreement or any inaccuracy of any representation, warranty or any other document to be delivered pursuant hereto or the failure of the Corporation to comply with any of its obligations hereunder or thereunder;

	(b)	any information or statement (except any information or statement relating to the Underwriters, or any of them, provided by the Underwriters) contained in any of the Prospectuses and the U.S. Placement Memorandum being or being alleged to be a misrepresentation or untrue or any omission or alleged omission to state in those documents any material fact (except facts relating to the Underwriters or any of them, provided by the Underwriters) required to be stated in those documents or necessary to make any of the statements therein not misleading in light of the circumstances in which they were made;

	(c)	any order made or any inquiry, investigation or proceeding instituted, threatened or announced by any court, securities regulatory authority or stock exchange or by any other competent authority, based upon any untrue statement, omission or misrepresentation or alleged untrue statement, omission or misrepresentation (except a statement, omission or misrepresentation relating to the Underwriters, or any of them, provided by the Underwriters) contained in any of the Prospectuses and the U.S. Placement Memorandum, which operates to prevent or restrict the trading in or the sale or distribution of the Shares;

	(d)	the Corporation not complying prior to the completion of the distribution of the Shares with any requirement of any Applicable Securities Laws relating to the Offering;

- 21 -

	(e)	any order made by any regulatory authority that trading in or distribution of any of the Corporation's securities is to cease or be suspended, or that trading by the directors, officers or promoters of the Corporation, or any one of them, shall cease or be suspended, including an order prohibiting the trade or distribution of any of the securities referred to herein;

	(f)	the failure or inability of the Corporation to allot, issue and deliver any or all of the certificates representing the Shares in a form and denomination satisfactory to the Underwriters at the time and place as the Underwriters may reasonably require for the completion of the transactions referred to herein; and

	(g)	a determination made by any competent authority setting aside the trade or distribution of any of the securities referred to herein, other than as a result of a breach by any of the Underwriters of its covenants herein.

and shall reimburse the Indemnified Parties for all reasonable costs, charges and expenses, as incurred, which any of them may pay or incur in connection with investigating or disputing any Claim or action related thereto including the fees and expenses of legal counsel on a solicitor and own client basis.

This indemnity shall be in addition to any liability which the Corporation may otherwise have.

9.2	If any Claim contemplated by this section 9 is asserted against any of the Indemnified Parties, or if any potential Claim contemplated by this section 9 comes to the knowledge of any of the Indemnified Parties, the Indemnified Party concerned shall notify in writing the Corporation as soon as reasonably practicable, of the nature of the Claim (provided that any failure to so notify in respect of any potential Claim shall not affect the liability of the Corporation under this section 9, except to the extent that such delay prejudices the Corporation's ability to contest such Claim). The Corporation shall, subject to the following, be entitled (but not required) to assume the defence on behalf of the Indemnified Party of any suit brought to enforce the Claim; provided that the defence shall be through legal counsel selected by the Corporation and acceptable to the Indemnified Party, acting reasonably, and no admission of liability shall be made by the Corporation without the prior written consent of the Indemnified Party. An Indemnified Party shall have the right to employ separate counsel in any such suit and participate in its defence but the fees and expenses of that counsel shall be at the expense of the Indemnified Parties unless:

	(a)	the Corporation fails to assume the defence of the suit on behalf of the Indemnified Party within thirty days of receiving notice of the suit;

	(b)	the employment of that counsel has been authorized in writing by the Corporation; or

	(c)	the named parties to the suit (including any added or third parties) including the Corporation and the Indemnified Party has been advised in writing by its outside counsel that representation of the Indemnified Party by counsel for the

- 22 -

Corporation is inappropriate as a result of the potential or actual conflicting interests of those represented;

(in each of the cases set out in subsections 9.2(a), (b) or (c), the Corporation shall not have the right to assume the defence of the suit on behalf of the Indemnified Party, but the Corporation shall be liable to pay the reasonable fees and expenses of separate counsel for all Indemnified Parties and, in addition, of local counsel in each applicable jurisdiction on a solicitor and own client basis). Notwithstanding the foregoing, no settlement may be made by an Indemnified Party without the prior written consent of the Corporation, which consent shall not be unreasonably withheld.

9.3	The Corporation hereby acknowledges and agrees that, with respect to this section 9, the Underwriters are contracting on their own behalf and as agents for their affiliates, directors, officers, employees and agents and their respective affiliates, directors, officers, employees and agents (collectively, the "Beneficiaries"). In this regard, each of the Underwriters shall act as trustee for the Beneficiaries of the covenants of the Corporation under this section 9 with respect to the Beneficiaries and accept these trusts and will hold and enforce those covenants on behalf of the Beneficiaries.

9.4	In order to provide for just and equitable contribution in circumstances in which an indemnity provided in section 9 would otherwise be available in accordance with its terms but is, for any reason not solely attributable to any one or more of the Indemnified Parties, held to be unavailable to or unenforceable by the Indemnified Parties or enforceable otherwise than in accordance with its terms, the Underwriters and the Corporation, as the case may be, shall contribute to the aggregate of all Claims (other than losses of profits in connection with the distribution of the Shares) of the nature contemplated in section 9 and suffered or incurred by the Indemnified Parties in proportions reflective of the relative benefits received by the Corporation and any Indemnified Party, as well as their relative fault and any other relevant equitable considerations, as determined by a court of competent jurisdiction; provided that the Underwriters shall not in any event be liable to contribute, in the aggregate, any amount in excess of the Underwriters' Fee or any portion actually received.

9.5	No party guilty of negligence, wilful misconduct, fraud or fraudulent misrepresentation or breach of any provision of this Agreement shall be entitled to claim indemnification under this section 9 or contribution under section 9.4 from any person who is not guilty of such negligence, wilful misconduct, fraud or fraudulent misrepresentation.

9.6	The rights to contribution provided in this section shall be in addition to and not in derogation of any other right to contribution which the Indemnified Parties may have by statute or otherwise at law provided that section 9.4 shall apply, mutatis mutandis, in respect of that other right.

9.7	The obligations under this section 9 shall apply whether or not the transactions contemplated by this Agreement are completed and shall survive the completion of the transactions contemplated under this Agreement and the termination of this Agreement.

- 23 -

10.	TERMINATION OF AGREEMENT

10.1	In addition to any other remedies which may be available to the Underwriters, this Agreement and any subscriptions for Shares received by the Underwriters may be terminated by the Underwriters upon delivery of written notice from the Lead Underwriter to the Corporation at any time up to the Closing of the Offering in any of the following events:

	(a)	there shall have occurred any material change or change in any material fact, or there shall be discovered any previously undisclosed material change or material fact which was required to be disclosed in the Prospectuses or otherwise, which, in each case, in the reasonable opinion of the Lead Underwriter, has or would be expected to have a material adverse effect on the market price or value of any of the shares of the Corporation, including without limitation the Shares;

	(b)	any inquiry, action, suit, investigation or other proceeding (whether formal or informal) is commenced, announced or threatened or any order is made by any federal, provincial, state, municipal or other governmental department, Commission, board, bureau, agency or other instrumentality including, without limitation, the Exchanges or any securities regulatory authority involving the Corporation or any of its officers or directors except for any such inquiry, investigation, proceeding or order based solely on the activities of the Underwriters and not of the Corporation which, in the opinion of the Lead Underwriter, acting reasonably, operates to prevent or restrict the trading of the shares of the Corporation or materially and adversely affects or will materially and adversely affect the market price or value of the shares of the Corporation or the distribution of the Shares, or adversely affects or might reasonably be expected to adversely affect the marketability, market price or value of the Shares;

	(c)	if there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence (including, without limitation, an act of terrorism) or any law or regulation which, in the opinion of the Lead Underwriter, adversely affects or involves, or will or could reasonably be expected to adversely affect or involve, the financial markets or the business, operations or affairs of the Corporation and its Subsidiaries, taken as a whole; or

	(d)	if there is a failure by the Corporation, or otherwise, of the satisfaction of any of the conditions precedent set out in section 7 of this Agreement.

The right of the Underwriters to terminate this Agreement is in addition to such other remedies any of the Underwriters may have in respect of any default, misrepresentation, act or failure to act of the Corporation in respect of any of the transactions contemplated by this Agreement.

- 24 -
