Dear Sir:

We understand that Crosshair Exploration & Mining Corp.
(the Corporation) proposes to issue and sell: (i) 8,000,000 units of
the Corporation (the Units); and (ii) 3,575,000 common shares of the
Corporation to be issued as flow-through shares (the Flow-Through
Shares) within the meaning of the Tax Act (as hereinafter defined). Upon
and subject to the terms and conditions contained herein, Canaccord Capital
Corporation (Canaccord) and Thomas Weisel Partners Canada Inc.
(collectively, the Underwriters and each individually an
Underwriter) hereby severally offer to purchase from the Corporation in
the respective percentages set forth in section 21 hereof, and the Corporation
hereby agrees to sell to the Underwriters, on a bought deal basis, all but not
less than all of the Units at a price of $1.25 per Unit (the Unit Issue
Price) for gross proceeds of $10,000,000 and agree to act as agents to
arrange for substituted purchasers for the Units resident in the Qualifying
Provinces (as hereinafter defined) or those jurisdictions outside Canada,
including the United States (as hereinafter defined), where the Units may be
lawfully sold pursuant to the terms and conditions hereof. The Units and
Flow-Through Shares are hereinafter collectively referred to as the Offered
Securities. The Underwriters also agree to offer the Flow-Through Shares as
agents to purchasers resident in the Qualifying Provinces at a price of $1.40
per Flow-Through Share (the FTS Issue Price) for gross proceeds of $5,005,000
). The Underwriters further agree that in the event that less than 3,575,000
Flow-Through Shares are sold by the Underwriters as agents, the Underwriters
will, subject to the terms and conditions set out herein, purchase as principal
the Flow-Through Shares not sold by the Underwriters as agents.

Each Unit shall consist of one common share of the Corporation
(a Unit Share) and one common share purchase warrant of the Corporation

$1.80 at any time before the date which is 18 months from the Closing Date.

The Corporation has also granted the Underwriters an option
(the Over-Allotment Option), exercisable in whole or in part in the
sole discretion of the Underwriters at any time prior to the 30th day
following the date of the closing of the Initial Offering, to purchase
additional Units (the Over-Allotment Units) or to offer as agents

provided that the Corporation shall not file any Supplementary Material or other
document without first obtaining from the Underwriters the approval of the
Underwriters, after consultation with the Underwriters with respect to the form
and content thereof, which approval will not be unreasonably withheld. The
Corporation shall in good faith discuss with the Underwriters any fact or change
in circumstances (actual, anticipated, contemplated or threatened, financial or
otherwise) which is of such a nature that there is or could be reasonable doubt
whether written notice need be given under this subsection 6(a).

      Securities there shall be any change in applicable Securities Laws which,
      in the opinion of the Underwriters, acting reasonably, requires the filing
      of any Supplementary Material, upon written notice from the Underwriters,
      the Corporation shall, to the satisfaction of the Underwriters, acting
      reasonably, promptly prepare and file any such Supplementary Material with
      the appropriate Canadian Securities Regulators where such filing is
      required.

      such covenants on behalf of the Beneficiaries.

The rights of indemnity contained in this section 18 shall not

person asserting any claim contemplated by this section 18 was not provided with
a copy of the Prospectus or Supplementary Material which corrects any untrue
statement or information, misrepresentation or omission which is the basis of
such claim and which is required under the Securities Laws to be delivered to
such person by the Underwriters or members of their banking or selling group (if
any).

      and the Corporation shall contribute to the aggregate of all claims,
      damages, liabilities, costs and expenses and all losses (other than losses
      of profits) of the nature contemplated in section 18 hereof and suffered
      or incurred by the Indemnified Parties in proportions such that the
      Underwriters shall be responsible for the portion represented by the
      percentage that the total Underwriters fee payable to the Underwriters
      bears to the aggregate purchase price of the Units and the Flow-Through
      Shares being offered by the Underwriters as agents, both as determined
      pursuant to the provisions hereof, and the Corporation shall, subject to
      subsection (b) of this section 19 be responsible for the balance, whether
      or not it has been sued or sued separately; provided that the Underwriters
      shall not in any event be liable to contribute, in the aggregate, any
      amount in excess of such total fee or any portion thereof actually
      received. However, no party who has engaged in any fraud, fraudulent
      misrepresentation or negligence shall be entitled to claim contribution
      from any person who has not engaged in such fraud, fraudulent
      misrepresentation or negligence.

shall be as to the following percentages:

If an Underwriter (a Refusing Underwriter) shall not
complete the purchase and sale of the Units which such Underwriter has agreed to
purchase hereunder for any reason whatsoever or to complete the sale as agent of
the Flow-Through Shares to the public, the other Underwriters (the
Continuing Underwriters) shall be entitled, at their option, to
purchase all but not less than all of the Units which would otherwise have been
purchased by such Refusing Underwriter pro rata according to the number
of Units to have been acquired by the Continuing Underwriters hereunder or in
such proportion as the Continuing Underwriters shall agree in writing and to
offer the Flow-Through Shares as agent to the public. If the Continuing
Underwriters do not elect to purchase the balance of the Units or to offer the
Flow-Through Shares as agent to the public pursuant to the foregoing:

| | (a) | the Continuing Underwriters shall not be obliged to
      purchase any of the Units that any Refusing Underwriter is obligated to

affiliate who makes any offers of the Offered Securities in the United States or
to U.S. Persons will do so solely as an agent for an Underwriter.

direction, consent, waiver, extension and other communication given or agreement
entered into by or on behalf of the Underwriters by Canaccord who shall
represent the Underwriters and have authority to bind the Underwriters
hereunder. In all cases, Canaccord shall use its best efforts to consult with
the other Underwriters prior to taking any action contemplated herein.
