Transfer.

General Restrictions.  The registered Holder of this Warrant, by its acceptance
hereof, agrees that it will not sell, transfer or assign or hypothecate this
Warrant to anyone except (i) to any “Permitted Transferee” (as defined in the
Shareholders Agreement), (ii) pursuant to the provisions of Clause 7.2.2 of the
Shareholders Agreement, or (iii) to a transferee of “Shares” (as defined in the
Shareholders Agreement) from the Holder or a Permitted Transferee (as defined in
the Shareholders Agreement) or a “BlueCrest Fund” (as defined in the
Shareholders Agreement) pursuant to and in accordance with Article 8.10 of the
articles of association of BF, in each case (a) in accordance with the
Shareholders Agreement and/or the articles of association of BF, as applicable,
and (b) upon compliance with, or pursuant to exemptions from, applicable
Federal, national, state, provincial and local securities laws.  In order to
make any permitted assignment, the Holder must deliver to the Company the
assignment form attached hereto duly executed and completed, together with this
Warrant and payment of all transfer taxes, if any, payable in connection
therewith.  The Company shall immediately transfer this Warrant on the books of
the Company and shall execute and deliver a new Warrant or Warrants
substantially similar in all material terms to the appropriate assignee(s)
expressly evidencing the right and obligation to purchase the aggregate number
of shares of Common Stock purchasable hereunder or such portion of such number
as shall be contemplated by any such assignment.

3.2

Restrictions Imposed by the Securities Act.  This Warrant, subject to the terms
hereof and the Shareholders Agreement, and the Warrant Shares underlying this
Warrant shall not be transferred unless and until (i) the Company has received
the opinion of counsel for the Holder that such securities may be transferred

Securities Act, which opinion is established to the reasonable satisfaction of
the Company, or (ii) a registration statement relating to such Warrant Shares
has been filed by the Company and declared effective by the Securities and

registration of this Warrant and the Warrant Shares for transfer or otherwise,
with any governmental authority.

this Warrant may be exercised or assigned in whole or in part.  In the event of
the exercise or assignment hereof in part only, upon surrender of this Warrant
for cancellation, together with the duly executed exercise or assignment form
and satisfaction of any Exercise Price and/or transfer tax, the Company shall
cause to be delivered to the Holder without charge a new Warrant or Warrants
substantially similar in all material terms to this Warrant in the name of the
Holder evidencing the right of the Holder to purchase the aggregate number of
shares of Common Stock purchasable hereunder as to which this Warrant has not
been exercised or assigned.

--------------------------------------------------------------------------------

4.2

Lost Certificate.  Upon receipt by the Company of evidence satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant and of reasonably
satisfactory indemnification, the Company shall execute and deliver a new
Warrant or Warrants substantially similar in all material terms and date. Any
such new Warrant executed and delivered as a result of such loss, theft,
mutilation or destruction shall constitute a substitute contractual obligation
on the part of the Company.

5.

Adjustments.

5.1

Adjustments to Exercise Price and Number of Securities.  The Exercise Price and
the number of shares of Common Stock underlying this Warrant shall be subject to
adjustment from time to time as hereinafter set forth:

5.1.1

Stock Dividends - Recapitalization, Reclassification, Split-Ups.  If after the
date hereof, and subject to the provisions of Section 5.2, the number of
outstanding shares of Common Stock is increased by a stock dividend on the
Common Stock payable in shares of Common Stock or by a split-up,
recapitalization or reclassification of shares of Common Stock or other similar
event, then, on the effective date thereof, the number of shares of Common Stock
issuable on exercise of this Warrant shall be increased in proportion to such
increase in outstanding shares.

5.1.2

Aggregation of Shares.  If after the date hereof, and subject to the provisions
of Section 5.2, the number of outstanding shares of Common Stock is decreased by
a consolidation, combination or reclassification of shares of Common Stock or
other similar event, then, upon the effective date thereof, the number of shares
of Common Stock issuable on exercise of this Warrant shall be decreased in
proportion to such decrease in outstanding shares of Common Stock.

5.1.3

Adjustments in Exercise Price.  Whenever the number of shares of Common Stock
purchasable upon the exercise of this Warrant is adjusted, as provided in this
Section 5.1, the Exercise Price shall be adjusted (to the nearest cent) by
multiplying such Exercise Price immediately prior to such adjustment by a
fraction (x) the numerator of which shall be the number of shares of Common
Stock purchasable upon the exercise of this Warrant immediately prior to such
adjustment, and (y) the denominator of which shall be the number of shares of
Common Stock so purchasable immediately thereafter.

5.1.4

Replacement of Securities upon Reorganization, etc.   In case the Company at any
time prior to the Expiration Date shall consolidate with or merge into any other
person, company or entity and the Company shall not be the continuing or
surviving corporation of such consolidation or merger (each, a “Triggering
Event”), the Holder of this Warrant shall have the right, upon the exercise
hereof at any time after  the consummation of such Triggering Event, but prior
to the Expiration Date and to the extent this Warrant is not exercised prior to
such Triggering Event, to receive, and shall accept, at the aggregate Exercise
Price in effect at the time immediately prior to the consummation of such
Triggering Event, in lieu of the shares of Common Stock issuable upon such
exercise of this Warrant prior to such Triggering Event, the securities, cash
and/or property to which such Holder would have been entitled upon the
consummation of such Triggering Event if such Holder had exercised the rights
represented by this Warrant immediately prior thereto, subject to adjustments
(subsequent to such corporate action) as nearly equivalent as possible to the
adjustments provided for in this Section 5. Notwithstanding anything herein to
the contrary, the rights under this Warrant, including the rights set forth in
this Section 5.1.4, shall terminate upon the completion by the Company of a plan
for, and filing with the Company’s state of incorporation of a notice of, its
dissolution, liquidation, winding up or similar action by the Company.

5.1.5

Changes in Form of Warrant.  The form of this Warrant need not be changed
because of any adjustments in the Exercise Price or the number and kind of
securities issuable upon the exercise of this Warrant.

5.2

Elimination of Fractional Interests.  The Company shall not be required to issue
certificates representing fractions of shares of Common Stock upon the exercise
of this Warrant, nor shall it be required to issue scrip or pay cash in lieu of
any fractional interests, it being the intent of the parties that all fractional
interests shall be eliminated by rounding any fraction up to the nearest whole
number of shares of Common Stock or other securities, properties or rights.

--------------------------------------------------------------------------------

6.

Validity and Reservation.  The Company represents and warrants that this Warrant
has been duly authorized and validly issued and is the binding obligation of the
Company enforceable in accordance with its terms, except as such enforceability
may be limited by bankruptcy, insolvency, reorganization, liquidation,
moratorium or other similar laws of general application and equitable principles
relating to or affecting creditors’ rights. The Company shall reserve and keep
available out of its authorized but unissued shares of Common Stock such number
of shares of Common Stock for which this Warrant may from time to time be
issuable. The Company covenants and agrees that, upon exercise of the Warrants
and payment of the Exercise Price therefore, all shares of Common Stock shall be
duly and validly issued, fully paid and non-assessable and not subject to
preemptive rights of any stockholder.

7.

Certain Notice Requirements.

7.1

Holder's Right to Receive Notice.  Nothing herein shall be construed as
conferring upon the Holder the right to vote or consent or to receive notice as
a stockholder for the election of directors or any other matter, or as having
any rights whatsoever as a stockholder of the Company with respect to this
Warrant or the Warrant Shares.  If, however, at any time prior to the Expiration
Date, any of the events described in Section 7.2 shall occur, then the Company
shall give written notice of such event at least ten days prior to the date
fixed as a record date or the date of closing the transfer books for the
determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on a proposed dissolution, liquidation, winding up or sale of all or
substantially all of its property, assets and business.  The notice shall
specify the record date or the date of the closing of the transfer books, as the
case may be.

7.2

Events Requiring Notice.  The Company shall be required to give the notice
described in this Section 7 upon one or more of the following events:  (i) if
the Company shall take a record of the holders of its shares of Common Stock for
the purpose of entitling them to receive a dividend, distribution, conversion of
or in respect of its Common Stock, (ii) the Company shall offer to all the
holders of its Common Stock any additional shares of capital stock of the
Company or securities convertible into or exchangeable for shares of capital
stock of the Company, or any option, right or warrant to subscribe therefore,
(iii) a merger or reorganization in which the Company is not the surviving
party, or (iv) a dissolution, liquidation or winding up of the Company (other
than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

7.3

Notice of Change in Exercise Price.  The Company shall, promptly after an event
requiring a change in the Exercise Price pursuant to Section 5 hereof, send
notice to the Holders of such event and change (“Price Notice”).  The Price
Notice shall describe the event causing the change and the method of calculating
same and shall be certified as being true and accurate by a senior officer of
the Company.

8.3

Binding Effect.  This Warrant shall inure solely to the benefit of and shall be
binding upon, the Holder and the Company and their respective successors, legal

respect of or by virtue of this Warrant or any provisions herein contained.

8.4

Governing Law; Submission to Jurisdiction.  This Warrant shall be governed by
and construed and enforced in accordance with the law of the State of Nevada,

8.5

Waiver, Etc.  The failure of the Company or the Holder to at any time enforce

thereafter enforce each and every provision of this Warrant. No waiver of any
breach, non-compliance or non-fulfillment of any of the provisions of this
Warrant shall be effective unless set forth in a written instrument executed by

Exercise Price or the arithmetic calculation of the Warrant Shares, the Company
shall submit the disputed determinations or arithmetic calculations via
facsimile within five (5) business days of receipt of the Notice of Exercise
giving rise to such dispute, as the case may be, to the Holder. If the Holder
and the Company are unable to agree upon such determination or calculation of
the Exercise Price or the Warrant Shares within five (5) business days of such
disputed determination or arithmetic calculation being submitted to the Holder,
then the Company shall, within three (3) business days submit via facsimile (a)
the disputed determination of the Exercise Price to an independent, reputable
investment bank selected by the Company, and reasonably acceptable to the
Holder, or (b) the disputed arithmetic calculation of the Warrant Shares to the
Company’s independent auditor. The Company shall cause at its expense the
investment bank or the auditor, as the case may be, to perform the
determinations or calculations and notify the Company and the Holder of the
results no later than ten (10) business days from the time it receives the
disputed determinations or calculations. Such investment bank’s or auditor’s
determination or calculation, as the case may be, shall be binding upon all
parties absent demonstrable error.

8.7

Enforcement.  In case any one or more of the provisions of this Warrant shall be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Warrant shall not in any way be affected
or impaired thereby and the parties will attempt in good faith to agree upon a
valid and enforceable provision which shall be a commercially reasonably
substitute therefore, and upon so agreeing, shall incorporate such substitute
provision in this Warrant.
