lead agent, “RBC”) and Canaccord Capital Corporation (an “Agent”
and together with RBC, the “Agents”) understand that Rockwell Ventures
Inc. (the “Company”) proposes to issue and sell up to CDN$50,024,000 of
units of the Company (the “Units”) at a subscription price of CDN$0.52
per Unit. Each Unit shall be comprised of one (1) common share in the capital of
the Company (a “Common Share”) and one (1) common share purchase warrant
of the Company (a “Warrant”). Each Warrant shall entitle the holder
thereof to acquire one (1) Common Share (a “Warrant Share”) on payment of
CDN$0.70 per Common Share prior to the close of business on the date that is 24
months from the Closing Date (as defined below). The offering of Units by the
Company is hereinafter referred to as the “Offering”.

     Upon and subject to the terms and
conditions set forth herein, the Agents hereby agree to act, and upon acceptance
hereof, the Company hereby appoints the Agents, as the Company’s sole and
exclusive agents, to offer for sale by way of private placement on a
commercially reasonable endeavours basis (and without underwriting liability) up
to CDN$50,024,000 of Units. The Agents shall be under no obligation to purchase
any of the Units.

     In consideration of the Agents’
services to be rendered in connection with the Offering, the Company shall pay
to RBC on behalf of the Agents a cash fee (the “Agency Fee”) in an amount
equal to 6% of gross proceeds realized by the Company on the issuance of the
Units pursuant to the Offering. As additional compensation for the services
provided, the Company shall grant to the Agents broker warrants (the “Broker
Warrants”) to purchase up to 5,772,000 Common Shares (the “Broker
Shares”). The Broker Warrants may be exercised, in whole or in part, during
the currency thereof, at an exercise price of CDN$0.52 per Broker Warrant, at
any time during the period commencing on the Closing Date and ending on the date
that is 24 months following the Closing Date.

     Notwithstanding the foregoing,
the Agents hereby agree to provide the Company with a selling concession (the
“Selling Concession”) in respect of the issuance of Units to purchasers
in South Africa, equal to $385,788, being 3% of the gross proceeds realized by
the Company on the issuance of Units to purchasers in such jurisdiction (with
24,730,000 Units issued to purchasers in South Africa for gross proceeds of
$12,859,600), which amount shall be deducted from the Agency Fee otherwise
payable pursuant to the paragraph above.

     As used in this Agreement, unless
the context otherwise requires, the terms “Units”, “Common Shares”, “Warrants”
and “Warrant Shares” shall include the Broker Units that may be issued on
exercise of the Broker Warrants, the Common Shares and Warrants that may be
issued on exercise of the Broker Units and the Warrant Shares that may be issued
on exercise of the Warrants comprising part of the Broker Units.

     Whether or not the Offering is
completed, the Company will pay all its own expenses related to the Offering
including, without limitation, the fees and disbursements of legal counsel,
auditors and accountants and service providers retained by the Company in
connection with the Offering, expenses related to roadshows and marketing
activities, printing costs and filing fees and taxes thereon. In addition,
whether or not the Offering is completed, the Company will reimburse the Agents
(forthwith upon receiving an account or accounts therefor) for all reasonable
out-of-pocket expenses incurred by the Agents in connection with the Offering,
including, but not limited to, travel and communication expenses, database

counsel to the Agents and taxes thereon, to a maximum of CDN$100,000
(collectively, the “Agents’ Expenses”) or as mutually agreed, with the
prior consent of the Company.

     If the Company agrees to pay a
commission or fee to anyone other than the Agents (including without limitation
any other agent, underwriter or financial advisor to the Company except for any
other registered dealers (or other dealers duly qualified in their respective
jurisdiction appointed by the Agents to assist in the Offering)), such
commission or fee will be for the Company’s account and will not reduce the
amount payable to the Agents hereunder.

     The fees and expenses of the
Agents and Agents’ counsel shall be payable at Closing (as defined below) as set
out herein.

     The Company agrees that the
Agents will be permitted to appoint other registered dealers (or other dealers

      applicable Securities Laws;

	 	 	 
		(b) 	
      on or prior to the Closing Date, unless it would be
      unlawful to do so or unless the Company, acting reasonably, determines

      applicable in the case of all certificates issued to the Agents or their
      nominee on behalf of any Purchasers;

	 	 	 
		(d) 	
      on or prior to the Closing Date, the Company will have
      taken all necessary steps to ensure the Common Shares and the Warrants
      comprising the Units will have been duly allotted for issue to the persons

	 	(h) 	
      the Company shall conduct the business of the Company in

	8.1 	
      Without the prior written consent of RBC, during the
      period commencing the date of this Agreement and ending on the day which
      is 120 days following the Closing Date, the Company will not, directly or
      indirectly, issue, offer, sell, contract to sell, grant any option or
      warrant to purchase, transfer, assign, pledge, secure or otherwise dispose
      of any Common Shares or financial instruments or any securities
      convertible into, or exercisable or exchangeable for any Common Shares, or
      make any short sale, engage in any hedging transaction or enter into any
      swap or other arrangement that has the effect of transferring, in whole or
      in part, any of the economic consequences of any of those securities,
      whether any such transaction described herein is to be settled by the
      delivery of Common Shares, other securities, cash or otherwise, or agree
      to do any of the foregoing, or announce any such intention to effect the
      foregoing (other than in connection with the completion of the
      Non-brokered private placement, the conversion or exchange of any
      securities of the Company outstanding as at the date hereof that are
      convertible or exchangeable for Common Shares or the completion of
      previously announced property acquisition transactions). Notwithstanding
      the foregoing restriction, the Company may (i) grant stock options
      pursuant to the Company’s stock option plan; and (ii) issue Common Shares
      upon

- 22 -

the exercise of securities outstanding
on the closing of the Offering (including stock options and warrants), provided
that such Common Shares, if issued to John Bristow, Mark Bristow, Ronald
Thiessen, David Copeland, Jeffrey Brenner, Jeffrey Mason, Rene Carrier, Scott
Cousens and Douglas Silver or otherwise held by the Company will also be subject
to the foregoing restrictions.

	9. 	
      Due Diligence.

	 	 
	9.1 	
      Until the Closing Date, the Company shall at all times
      allow the Agents and their representatives to conduct all due diligence
      investigations, examinations and oral due diligence sessions which the
      Agents may reasonably require in order to fulfil their obligations as
      Agents. The Company agrees to use its best efforts to assist the Agents
      with their due diligence investigations. The Company will provide such
      information as to its financial condition, business, properties, title,
      assets and affairs (including any material contracts) as may reasonably be
      requested by the Agents, which information, if not in the public domain
      and if not included in any offering materials approved by the Company,
      will be kept confidential by the Agents, provided that the Agents shall
      have the right to disclose such confidential information to their
      professional advisers for legal, accounting and tax advice purposes and
      except as otherwise required by law.

	 	 
	9.2 	
      The Company will provide to the Agents all corporate,
      financial and operating information and documentation regarding the
      Company, the Securities and the Offering, and will provide access to its
      senior management, facilities, employees, auditors, legal counsel and
      consultants, which are reasonably necessary and sufficient to allow the
      Agents to perform their services hereunder. Without restricting any of the
      foregoing, the Company will provide the Agents with copies of any
      forecasts and projections prepared by, or on behalf of the
  Company.

	 	 
	10. 	
      Indemnity and Contribution.

	 	 
	10.1 	
      The Company agrees to indemnify and save harmless the
      Agents, their affiliates and their respective directors, officers,
      employees, partners, agents, advisors and shareholders (collectively, the
      “Indemnified Parties” and individually, an “Indemnified
      Party”) from and against any and all losses, claims, actions, suits,
      proceedings, damages, liabilities or expenses of whatsoever nature or kind
      (excluding loss of profits), including the aggregate amount paid in
      reasonable settlement of any actions, suits, proceedings, investigations
      or claims and the reasonable fees, disbursements and taxes of their
      counsel in connection with any action, suit, proceeding, investigation or
      claim that may be made or threatened against any Indemnified Party or in
      enforcing this indemnity (each a “Claim”, collectively, the
      “Claims”) to which an Indemnified Party may become subject or
      otherwise involved in any capacity insofar as the Claims relate to, are
      caused by, result from, arise out of or are based upon, directly or
      indirectly, the transaction contemplated hereby whether performed before
      or after the Company’s execution of this Agreement and to reimburse each
      Indemnified Party forthwith, upon demand, for any legal or other expenses
      reasonably incurred by such Indemnified Party in connection with any
      Claim.

- 23 -

	10.2 	
      The Company also agrees that no Indemnified Party shall
      have any liability (either direct or indirect, in contract, tort or
      otherwise) to the Company or any person asserting claims on the Company’s
      behalf or in right for or in connection with the transaction contemplated
      hereby, except to the extent that any losses, expenses, claims, actions,
      damages or liabilities incurred by the Company are determined by a court
      of competent jurisdiction in a final judgement that has become
      non-appealable to have resulted from the negligence or wilful misconduct
      of such Indemnified Party.

	 	 	 
	10.3 	
      In the event and to the extent that a court of competent
      jurisdiction in a final judgement that has become non-appealable
      determines that an Indemnified Party was negligent or guilty of wilful
      misconduct in connection with a Claim in respect of which the Company has
      advanced funds to the Indemnified Party pursuant to this indemnity, such
      Indemnified Party will reimburse such funds to the Company and thereafter
      this indemnity will not apply to such Indemnified Party in respect of such
      Claim. The Company agrees to waive any right the Company might have of
      first requiring the Indemnified Party to proceed against or enforce any
      other right, power, remedy or security or claim payment from any other
      person before claiming under this indemnity.

	 	 	 
	10.4 	
      In case any action, suit, proceeding or claim is brought
      against an Indemnified Party or an Indemnified Party has received notice
      of the commencement of any investigation in respect of which indemnity may
      be sought against the Company, the Indemnified Party will give the Company
      prompt written notice of any such action, suit, proceeding, claim or
      investigation of which the Indemnified Party has knowledge and the Company
      will undertake the investigation and defence thereof on behalf of the
      Indemnified Party, including the prompt employment of counsel acceptable
      to the Indemnified Parties affected and the payment of all expenses.
      Failure by the Indemnified Party to so notify will not relieve the Company
      of its obligation of indemnification hereunder unless (and only to the
      extent that) such failure results in forfeiture by the Company of
      substantive rights or defences.

	 	 	 
	10.5 	
      No admission of liability and no settlement, compromise
      or termination of any action, suit, proceeding, claim, or investigation
      will be made without the Company’s consent and the consent of the
      Indemnified Parties affected, such consents not to be unreasonably
      withheld. Notwithstanding that the Company will undertake the
      investigation and defence of any Claim, an Indemnified Party will have the
      right to employ separate counsel with respect to any Claim and participate
      in the defence thereof, but the fees and expenses of such counsel will be
      at the expense of the Indemnified Party unless:

	 	 	 
		(i) 	
      employment of such counsel has been authorized in writing
      by the Company;

	 	 	 
		(ii) 	
      the Company has not assumed the defence of the action
      within a reasonable period of time after receiving notice of the
    claim;

- 24 -

	 	(iii) 	
      the named parties to any such claim include both the
      Company and the Indemnified Party and the Indemnified Party will have been
      advised by counsel to the Indemnified Party that there may be a conflict
      of interest between the Company and the Indemnified Party; or

	 	 	 
	 	(iv) 	
      there are one or more defences available to the
      Indemnified Party which are different from or in addition to those
      available to the Company;

in which case such fees and expenses of
such counsel to the Indemnified Party will be for the Company’s account. The
rights accorded to the Indemnified Parties hereunder will be in addition to any
rights an Indemnified Party may have at common law or otherwise.

	10.6 	
      The Company also agrees that no Indemnified Party shall
      have any liability (whether direct or indirect, in contract or tort or
      otherwise) to the Company or any person asserting claims on behalf of or
      in right of the Company for or in connection with the engagement except to
      the extent any losses, expenses, claims, actions, damages or liabilities
      incurred by the Company are determined by a court of competent
      jurisdiction in a final judgment that has become non-appealable to have
      resulted primarily from the negligence or willful misconduct of such
      Indemnified Party. The Company will not, without the Agents’ prior written
      consent, settle, compromise, consent to the entry of any judgement in or
      otherwise seek to terminate any action suit, proceeding, investigation or
      claim in respect of which indemnification may be sought hereunder (whether
      or not any Indemnified Party is a party thereto) unless such settlement,
      compromise, consent or termination includes a release of each Indemnified
      Party from any liabilities arising out of such action, suit, proceeding,
      investigation or claim.

	 	 
	10.7 	
      The foregoing indemnity shall not apply to the extent
      that a court of competent jurisdiction in a final judgment that has become
      non-appealable shall determine that such losses, expenses, claims,
      actions, damages or liabilities to which the Indemnified Party may be
      subject were primarily caused by the negligence or willful misconduct of
      the Indemnified Party.

	 	 
	10.8 	
      The Company agrees to waive any right the Company may
      have of first requiring the Indemnified Party to proceed against or
      enforce any right, power, remedy or security or claim payment from any
      other person before claiming under this section.

	 	 
	10.9 	
      If for any reason the foregoing indemnification is
      unavailable (other than in accordance with the terms hereof) to the
      Indemnified Parties (or any of them) or is insufficient to hold them
      harmless, the Company will contribute to the amount paid or payable by the
      Indemnified Parties as a result of such Claims in such proportion as is
      appropriate to reflect not only the relative benefits received by the
      Company or the Company’s shareholders on the one hand and the Indemnified
      Parties on the other, but also the relative fault of the parties and other
      equitable considerations which may be relevant. Notwithstanding the
      foregoing, the Company will in any

- 25 -

event contribute to the amount paid or
payable by the Indemnified Parties as a result of such Claim any amount in
excess of the fees actually received by the Indemnified Parties hereunder.

	10.10 	
      The Company hereby constitutes each of the Agents to act
      as trustee for its respective Indemnified Parties of the Company’s
      covenants under this indemnity with respect to such persons and each of
      the Agents agrees to accept such trust and to hold and enforce such
      covenants on behalf of such persons.

	 	 	 
	10.11 	
      The Company agrees to reimburse the Agents monthly for
      the time spent by the Agents’ respective personnel in connection with any
      Claim at their normal per diem rates. The Company also agrees that if any
      action, suit, proceeding or claim will be brought against, or an
      investigation commenced in respect of the Company or the Company and the
      Agents and personnel of the Agents will be required to testify,
      participate or respond in respect of or in connection with the transaction
      contemplated hereby, the Agents will have the right to employ their own
      counsel in connection therewith and the Company will reimburse the Agents
      monthly for the time spent by their respective personnel in connection
      therewith at their normal per diem rates together with such disbursements
      and reasonable out-of-pocket expenses as may be incurred, including fees
      and disbursements of Agents’ counsel.

	 	 	 
	11.

      Termination.

	 	 	 
	13.1 	
      All terms and conditions set out in Section 11 herein
      shall be construed as conditions and any breach or failure by the Company
      to comply with any such conditions in favour of the Agents shall entitle

      notice to that effect given to the Company prior to the Closing Time. The

      this agreement to be satisfied. It is understood that the Agents may waive
      in whole or in part, or extend the time for compliance with, any of such
      terms and conditions without prejudice to their rights in respect of any
      subsequent breach or non- compliance, provided that to be binding on the

		(b) 	
      there shall have occurred any change in the Securities
      Laws, or any inquiry, investigation or other proceeding is announced,

      to any statute of Canada or the Qualifying Jurisdictions or any policy,
      rule, regulation or order of the TSX-V in relation to the Company or any
      of its securities, which, in the opinion of the Agents (or any of them),
      acting reasonably and in good faith, prevents or restricts the
      distribution of the Units or adversely affects or might reasonably be
      expected to adversely affect the market price or value of the
  Units;

	 	 	 
		(c)

      of the U.S. Exchange Act or exempt from such reporting requirements
      pursuant to Rule 12g3-2(b) thereunder, the Company will provide to any
      holder of such Securities, or to any prospective purchaser of such
      Securities designated by such holder, upon the request of such holder or
      prospective purchaser, at or prior to the time of resale, the information
      required to be provided by Rule 144A(d)(4); and

	 	 
	17. 	
      except with respect to the offer and sale of the Units
      offered hereby, the Company has not, for a period of six months prior to
      the date hereof sold, offered for sale or solicited any offer to buy any
      of its securities in the United States in a manner that would be
      integrated with the offer and sale of the Units and would cause the
      applicable exemptions from registration to become unavailable with respect
      to the offer and sale of the Units.

Terms and Conditions of Subscription

Terms of the Offering

Each unit (each, a “Unit”) is comprised of (i) one
common share of the Corporation (each, a “Common Share”) and (ii)
one common share purchase warrant of the Corporation (each, a “Warrant”).
Each Warrant entitles the holder to acquire, on payment of $0.70 ,
one Common Share (each, an “Underlying Share”). A Warrant may be
exercised at any time during the 24 month period starting on the date the Units
are issued. As used in this Agreement, “Securities” means the Common
Shares and Warrants comprising the Units and Underlying Shares, collectively or
individually, as the context requires.

The Corporation intends to sell up to $50 million of Units
(the “Offering”) pursuant to the terms of an agency agreement (the
“Agency Agreement”) to be entered into between RBC

Dominion Securities Inc. (“RBC”) and Canaccord
Capital Corporation (collectively, the “Agents”) and also intends to sell
$10 million of Units pursuant to a non-brokered private placement on the same
terms as the Offering. The Offering is being made by the Agents on a “best
efforts” private placement basis without underwriting liability. The brokered
offering is subject to a condition, which may be waived at the option of the
Agents, that the non-brokered private placement close concurrently with the
Offering.

The Securities will be offered in Canada, the United Kingdom
and the United States through the Agents and its broker dealer affiliates, and
in certain other jurisdictions as contemplated by the Agency Agreement. 

The specific attributes of the Warrants will be set forth in
the Warrant certificates. 

The net proceeds from the Offering will be released to the
Corporation on the Closing Date.

The Agent(s) will receive from the Corporation a fee equal
to 6% of the aggregate gross proceeds of the Offering payable upon completion of
the purchase from the Corporation of the Securities and, subject to the terms of
the Agency, will be entitled to reimbursement of certain of its expenses
incurred in connection with the Offering.

The Agents will also receive broker warrants (“Broker
Warrants“) which will entitle the Agents to purchase, at $0.52 per Common
Share, up to that number of Common Shares equal to 6% of the number of Units
sold pursuant to the Offering, which Broker Warrants will be exercisable at any
time prior to 5:00 p.m. (Vancouver time) on the date which is 24 months
following the Closing Date.

Closing

     The completion of the offer, sale
and issuance of the Securities as contemplated by this Agreement (the
“Closing”) will occur on or about May 8, 2007 at 9:00 a.m. or such other
date and time as may be determined by the Corporation and the Agents (the
“Closing Date” and the “Time of Closing”, respectively), subject
to satisfaction or waiver by the relevant party of the conditions of
closing.

Conditions of Closing

     The Subscriber, on its own behalf
and on behalf of any disclosed principal for whom the Subscriber is contracting
under this Agreement (a “Disclosed Beneficial Subscriber”), acknowledges
that the offer, sale and issuance of the Securities as contemplated by this
Agreement is subject to, among other things, the following conditions being
fulfilled or performed on or before the Time of Closing, which conditions are
for the exclusive benefit of the Corporation and may be waived, in whole or in
part, by the Corporation in its sole discretion:

The representations and warranties of the Subscriber having

correct at the Time of Closing.

Acknowledgments of the Subscriber

     The Subscriber, on its own behalf
and, if applicable, on behalf of any Disclosed Beneficial Subscriber,
acknowledges that:

AN INVESTMENT IN THE UNITS IS SPECULATIVE AND NOT WITHOUT
RISK AND THE SUBSCRIBER (AND ANY DISCLOSED BENEFICIAL SUBSCRIBER) MAY
LOSE ITS ENTIRE INVESTMENT; 

The Corporation may complete additional financings in the
future in order to develop the business of the Corporation and fund its ongoing
development, and such future financings may have a dilutive effect on current
securityholders of the Corporation, including the Subscriber but there is no
assurance that such financing will be available, on reasonable terms or at all,
and if not available, the Corporation may be unable to fund its ongoing
development;

The Corporation has the right to accept or reject the
Subscriber’s subscription in whole or in part. If the subscription is rejected
in whole or in part all or a portion of the purchase price, as the case may be,
will be promptly delivered to the Subscriber, without interest;

The Subscriber is not relying upon the Agents to conduct any
due diligence investigation on behalf of the Subscriber concerning the
Corporation’s business, financial position, condition or prospects;

The offer, sale and issuance of the Securities is exempt from
the prospectus and registration requirements of Applicable Securities Laws and,
as a result: (i) the Subscriber may not receive information that would otherwise
be required under Applicable Securities Laws or be contained in a prospectus
prepared in accordance with Applicable Securities Laws, (ii) the Subscriber is
restricted from using most of the protections, rights and remedies available
under Applicable Securities Laws, including statutory rights of rescission or
damages, and (iii) the Corporation is relieved from certain obligations that
would otherwise apply under Applicable Securities Laws; 

No prospectus has been filed with any Regulator in connection
with the Offering and no Regulator (including without limitation, the United
States Securities and Exchange Commission or any state securities commission)
has made any finding or determination as to the merit for investment in, or made
any recommendation or endorsement with respect to, the Securities;

The offer and sale of the Securities by the Corporation to the
Subscriber have not been and will not be registered under the United States
Securities Act of 1933, as amended (the “U.S. Securities Act”), or any
state securities laws, and the Securities may not be offered or sold in the
United States or to a U.S. Person (as defined in Rule 902 of Regulation S under
the U.S. Securities Act) except in compliance with the requirements of an
exemption from registration under the U.S. Securities Act and any applicable
state securities laws and that the Securities are being offered and sold by the
Corporation to a limited number of Institutional Accredited Investors (as

8

- 9 -

defined in Schedule “C” hereto), including the Subscriber, that
execute and deliver this Agreement and make the representations and warranties
herein and as set forth in Schedule “C” in transactions not requiring
registration under the U.S. Securities Act; accordingly, there are substantial
restrictions on the transferability of the Securities by the Subscriber;

As a condition of the purchase of the Securities, the
Subscriber will be required to, among other things, execute and deliver to or as
directed by the Corporation, this Subscription Agreement, including the United
States Institutional Accredited Investor Certificate attached as Schedule “C” to
this Subscription Agreement;

Any information concerning the Corporation available in its
public record (meaning information which has been publicly filed at
www.SEDAR.com by the Corporation pursuant to a requirement under Applicable
Securities Laws (the “Public Record”)) obtained by the Subscriber is
without independent investigation or verification by the Agents. The Agents and
its respective directors, officers, employees, agents and representatives are
not responsible for the preparation of any documents in the Public Record and
have not and will not confirm (i) the accuracy or adequacy of any information
contained in the Public Record, or (ii) whether all information concerning the
Corporation that is required to be disclosed or filed by the Corporation under
Applicable Securities Laws has been disclosed or filed;

The purchase of Units forms part of a larger issuance and sale
by the Corporation of up to $50 million of Units as well as an additional $10
million of Units on a non-brokered private placement basis;

This Agreement sets out the principal terms and conditions of
the Subscriber’s purchase of Units which can be modified by agreement between
the Agents and the Corporation;

The Corporation may be required to disclose to Regulators the
name and address of the beneficial purchasers of the Units, the number of Units
purchased and the purchase price for such Units;

The Securities are being offered on a “private placement”
basis. The Warrants are not and will not be listed on any stock exchange and
will be subject to resale restrictions under Applicable Securities Laws. The
Common Shares and the Underlying Shares will be listed and quoted for trading on
the facilities of the TSX Venture Exchange (the “Exchange”) and will be
subject to resale restrictions under Applicable Securities Laws and the rules of
the Exchange, and the Corporation may make a notation on its records or give
instructions to any transfer agent of the Common Shares in order to implement
such resale restrictions;

The certificates representing the Common Shares, the Warrants
and the Underlying Shares (and any replacement certificate issued prior to the
expiration of the applicable hold periods), or ownership statements issued under
a direct registration system or other electronic book-entry system, will bear a
legend in accordance with Applicable Securities Laws;

Until the expiry of the hold periods, the Common Shares and
Underlying Shares can not be traded through the facilities of the Exchange since
the certificates representing the Common Shares and Underlying Shares are not
freely transferable and consequently are not “good delivery” in settlement of
transactions on the Exchange. The Exchange would deem the Subscriber to be
responsible for any loss incurred on a sale made by the Subscriber in the
Units;

9

- 10 -

The costs incurred by the Subscriber (including any fees and
disbursements of any special counsel retained by the Subscriber) relating to the
purchase of the Units by the Subscriber shall be borne by the Subscriber;

The Subscriber acknowledges that the Agents will receive from
the Corporation a commission in connection with the sale of the Units and that
the Agents assume no responsibility or liability of any nature whatsoever for
any information upon which the Subscriber’s decision to purchase the Units was
made, or as to whether all information concerning the Corporation or required to
be disclosed by the Corporation or has been generally disclosed and that the
Agents have not engaged in any independent investigation or verification with
respect to the accuracy or completeness of any of the representations or
warranties of the Corporation set forth in this Agreement; 

The Units may not be sold in Canada or to Canadian residents
unless the sale is made pursuant to an available exemption from the prospectus
and registration requirements under the securities legislation in the Canadian
purchaser’s province or territory of residence or the required “hold” period
under Canadian securities legislation has expired since the acquisition by it of
the Units to be sold; 

The Corporation (i) is under no obligation to be or to remain a
“foreign issuer”, as such term is defined in the U.S. Securities Act, (ii) may
not, at the time the Subscriber sells the Units or at any other time, be a
foreign issuer, and (iii) may engage in one or more transactions which could
cause the Corporation not to be a foreign issuer. If the Corporation is not a
foreign issuer at the time of any sale pursuant to Rule 904 of Regulation S
adopted by the United States Securities and Exchange Commission (the
“SEC”), the certificate delivered to the buyer may continue to bear the
applicable legend; 

The certificates representing the Common Shares and the
Underlying Shares (and any replacement certificate issued prior to the
expiration of the applicable hold periods) will bear a legend substantially in
the form of the following legend as required by the Exchange:

“UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF
THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE SEPTEMBER 9, 2007.” [Four
months plus one day from the Closing Date]

“WITHOUT PRIOR WRITTEN APPROVAL OF THE TSX VENTURE EXCHANGE AND
COMPLIANCE WITH ALL APPLICABLE SECURITIES LEGISLATION, THE SECURITIES
REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR
