      TO REGULATION S PROMULGATED UNDER THE U.S. SECURITIES ACT OF 1933, AS
      AMENDED (THE "ACT"). AS SUCH, THE SECURITIES REPRESENTED BY THIS

                                       3

<page>

      and

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO
      STOCK EXCHANGE ("TSX"); HOWEVER, PRIOR TO FEBRUARY 19, 2008 THE SAID
      SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE
      NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING
      SUCH SECURITIES IS NOT "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON
      TSX PRIOR TO SUCH DATE."

            (b)   If shares of Common Stock are issued to a Canadian resident
      upon exercise of this Warrant prior to February 19, 2008, each certificate
      for such shares of Common Stock shall, in addition to the legend in
      Section 1.5(a), bear the following legend:

2.    PROCEDURE FOR EXERCISE.

      2.1   DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. The Corporation
agrees that the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder as the owner of record of such shares
as of the close of business on the date on which the duly completed and executed
Subscription Form, this Warrant Certificate and payment for such shares shall
have been received by the Corporation in accordance herewith. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within five (5) business days thereafter, the Corporation at the
Corporation's expense (including the payment by it of any applicable issue
taxes) will cause to be issued in the name of and delivered to the Holder, or as
such Holder (upon payment by such Holder of any applicable transfer taxes) may
direct in compliance with applicable securities laws, a certificate or
certificates for the number of duly and validly issued, fully paid and
nonassessable shares of Common Stock (or Other Securities) to which such Holder
shall be entitled on such exercise. As to any fraction of a share that the
Holder of one or more Warrants, the rights under which are exercised in the same
transaction, would otherwise be entitled to purchase upon such exercise, the
Corporation shall pay to such Holder an amount in cash equal to such fraction
multiplied by the Fair Market Value of one share of Common Stock on the date of
exercise. Following a partial exercise of this Warrant prior to the Expiration
Date, the Corporation shall cancel this Warrant Certificate and, within five
business days, execute and deliver to the Holder a new Warrant Certificate of
like tenor covering the remaining balance of the shares of Common Stock subject
to this Warrant Certificate.

                                       4

<page>

      2.2   EXERCISE. Payment may be made by certified check or bank draft
payable to the order of the Corporation equal to the applicable aggregate
Exercise Price, for the number of Common Shares specified in such Subscription
Form (as such exercise number shall be adjusted to reflect any adjustment in the
total number of shares of Common Stock issuable to the Holder in accordance with
the terms of this Warrant) and the Holder shall thereupon be entitled to receive
the number of duly authorized, validly issued, fully-paid and non-assessable
shares of Common Stock (or Other Securities) determined as provided herein.

      2.3   REPRESENTATION. The Holder of this Warrant has represented to the
Corporation that it is acquiring this Warrant for its own account and not with a
view toward, or for resale in connection with, the public sale or distribution
of this Warrant or the underlying shares of Common Stock, except pursuant to
sales registered or exempted under the Securities Act of 1933, as amended (the
"Securities Act"). The Holder of this Warrant further represented that as of the
Issue Date, the Holder, was purchasing the Shares in compliance with securities
laws in its jurisdiction of residence and pursuant to an exemption from any
prospectus or securities registration requirements available to the Corporation
and the Holder under applicable securities laws of their jurisdiction of
resident or to which the Holder is otherwise subject. Upon exercise of this
Warrant, the Holder shall, if requested by the Corporation, confirm in writing,
in a form satisfactory to the Corporation, representations concerning the
matters described in this Section 2.3.

3.    EFFECT OF REORGANIZATION, ETC.; ADJUSTMENT OF EXERCISE PRICE.

      3.1   REORGANIZATION, CONSOLIDATION, MERGER, ETC. If at any time or from
time to time, the Corporation (a) effects a reorganization, (b) consolidates
with or merges into any other person, or (c) transfers all or substantially all
of its properties or assets to any other person under any plan or arrangement
contemplating the dissolution of the Corporation, then, in each such case, as a
condition to the consummation of such a transaction, proper and adequate
provision shall be made by the Corporation whereby the Holder of this Warrant,
on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

      3.2   DISSOLUTION. In the event of any dissolution of the Corporation
following the transfer of all or substantially all of its properties or assets,
the Corporation, concurrently with any distributions made to holders of its
Common Stock, shall at its expense deliver or cause to be delivered to the
Holder the stock and other securities and property (including cash, where
applicable) receivable by the Holder of this Warrant pursuant to Section 3.1, or
if the Holder also instructs the Corporation, to a bank or trust company
specified by the Holder as trustee for the Holder (the "Trustee").

                                       5

<page>

      3.3   CONTINUATION OF TERMS. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Corporation, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. If this
Warrant does not continue in full force and effect after the consummation of the
transactions described in this Section 3, then the Corporation's securities and
property (including cash, where applicable) receivable by the Holder of this
Warrant will be delivered to the Holder or the Trustee as contemplated by
Section 3.2.

4.    EXTRAORDINARY EVENTS REGARDING COMMON STOCK.

      If the Corporation (a) issues additional shares of the Common Stock as a
dividend or other distribution on outstanding Common Stock or any preferred
stock issued by the Corporation, (b) subdivides its outstanding shares of Common
Stock, or (c) combines its outstanding shares of the Common Stock into a smaller
number of shares of the Common Stock, then, in each such event, the Exercise
Price shall, simultaneously with the happening of such event, be adjusted by
multiplying the then Exercise Price by a fraction, the numerator of which shall
be the number of shares of Common Stock outstanding immediately prior to such
event and the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such event, and the product so obtained shall
thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive event or events described herein in this Section 4. The number of
shares of Common Stock that the Holder of this Warrant shall thereafter, on the
exercise hereof as provided herein in Section 1, be entitled to receive shall be
adjusted to a number determined by multiplying the number of shares of Common
Stock that would otherwise (but for the provisions of this Section 4) be
issuable on such exercise by a fraction of which (a) the numerator is the
Exercise Price that would otherwise (but for the provisions of this Section 4)
be in effect, and (b) the denominator is the Exercise Price in effect on the
date of such exercise.

5.    CERTIFICATE AS TO ADJUSTMENTS.

      In each case of any adjustment or readjustment in the shares of Common
Stock (or Other Securities) issuable on the exercise of the Warrant as provided
for in Section 3 or 4 above, the Corporation at its expense will promptly cause
its Chief Financial Officer or other appropriate designee to compute such
adjustment or readjustment in accordance with the terms of the Warrant and
prepare a certificate setting forth such adjustment or readjustment and showing
in detail the facts upon which such adjustment or readjustment is based,
including a statement of (a) the consideration received or receivable by the
Corporation for any additional shares of Common Stock (or Other Securities)
issued or sold or deemed to have been issued or sold, (b) the number of shares
of Common Stock (or Other Securities) outstanding or deemed to be outstanding,
and (c) the Exercise Price and the number of shares of Common Stock to be
received upon exercise of this Warrant, in effect immediately prior to such
adjustment or readjustment and as adjusted or readjusted as provided in this
Warrant. The Corporation will forthwith mail or cause to be mailed a copy of
each such certificate to the Holder of this Warrant.

                                       6

6.    RESERVATION OF STOCK, ETC. ISSUABLE ON EXERCISE OF WARRANT.

      The Corporation will at all times reserve and keep available, solely for
issuance and delivery on the exercise of this Warrant, shares of Common Stock
(or Other Securities) from time to time issuable on the exercise of this
Warrant.

7.    ASSIGNMENT; EXCHANGE OF WARRANT.

      Subject to compliance with applicable securities laws, this Warrant, and
the rights evidenced hereby, may be transferred by any registered holder hereof
(a "Transferor") in whole or in part. On the surrender for exchange of this
Warrant, with the Transferor's endorsement in the form of Exhibit B (the
"Transferor Endorsement Form"), together with evidence reasonably satisfactory
to the Corporation demonstrating compliance with applicable securities laws in a
manner consistent with the restrictive legend on this Warrant, the Corporation
at the Corporation's expense (but with payment by the Transferor of any
applicable transfer taxes), will cause to be issued and delivered to or on the
order of the Transferor thereof a new Warrant of like tenor, in the name of the
Transferor and/or the transferee(s) specified in such Transferor Endorsement
Form (each a "Transferee"), calling in the aggregate on the face or faces
thereof for the number of shares of Common Stock called for on the face or faces
of the Warrant so surrendered by the Transferor.

8.    REPLACEMENT OF WARRANT.

      On receipt of evidence reasonably satisfactory to the Corporation of the
loss, theft, destruction or mutilation of this Warrant and, in the case of any
such loss, theft or destruction of this Warrant, on delivery of an indemnity
agreement and surety bond reasonably satisfactory in form and amount to the
Corporation, the Corporation at the Holder's expense and Holder's payment of
charges of the Corporation, will execute and deliver, in lieu thereof, a new
Warrant of like tenor.

9.    EXERCISE RESTRICTIONS.

      9.1   LIMITATION ON NUMBER OF SHARES ISSUABLE. Notwithstanding anything
contained herein to the contrary, the rights represented by this Warrant shall
not be exercisable by the Holder and the Corporation shall not give effect to
any such exercise, if and solely to the extent that after giving effect to such
exercise, the Holder, together with any person or company acting jointly or in
concert with the Holder with respect to the voting of voting securities of the
Corporation (the "Joint Actors") would in the aggregate directly or indirectly
own or exercise control or direction over the voting of that number of voting
securities of the Corporation (not including shares subject to a warrant as to
which no notice of exercise and corresponding payment has been delivered) that
is 19.99% or greater of the total issued and outstanding voting securities of
the Corporation after giving effect to such exercise.

      9.2   PROVISION OF OFFICER'S CERTIFICATE. Prior to exercising the rights
represented by this Warrant, the Holder shall provide the Corporation with an
officer's certificate stating the number of voting securities of the Corporation
held by the Holder and its Joint Actors, if any, as of the date provided for in
the exercise notice (the "Officer's Certificate") and the Corporation shall be
entitled to rely on the Officer's Certificate in making any determinations
regarding the total issued and outstanding voting securities of the Corporation
to be held by the Holder and its Joint Actors, if any, after giving effect to
the exercise. The execution of the Subscription Form by the Holder will suffice
as the Holder's acknowledgement of compliance with such exercise limits as set
forth in this Section 9.

                                       7

10.   TRANSFER ON THE CORPORATION'S BOOKS.

Corporation may treat the registered Holder hereof as the absolute owner hereof
for all purposes, notwithstanding any notice to the contrary.

11.   NOTICES, ETC.

      All notices and other communications from the Corporation to the Holder of
this Warrant shall be delivered by ordinary surface or air mail, postage
prepaid, addressed to the Holder or delivered at their respective address
appearing on the register of Holders.

12.   MISCELLANEOUS.

      Notwithstanding any provision to the contrary contained in this Warrant,
no Common Stock will be issued pursuant to the exercise of this Warrant if the
issuance of such securities may constitute a violation of the securities laws of
any applicable jurisdiction. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF STATE OF CALIFORNIA WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
LAWS. ANY ACTION BROUGHT CONCERNING THE TRANSACTIONS CONTEMPLATED BY THIS
WARRANT SHALL BE BROUGHT ONLY IN THE STATE COURTS OF CALIFORNIA OR IN THE
FEDERAL COURTS LOCATED IN THE STATE OF CALIFORNIA. The Holder and the
Corporation shall submit to the jurisdiction of such courts and waive trial by
jury. The prevailing party shall be entitled to recover from the other party its
reasonable attorney's fees and costs. If any provision of this Warrant is
invalid or unenforceable under any applicable statute or rule of law, then such
provision shall be deemed inoperative to the extent that it may conflict
therewith and shall be deemed modified to conform with such statute or rule of
law. Any such provision which may prove invalid or unenforceable under any law
shall not affect the validity or enforceability of any other provision of this
Warrant. The headings in this Warrant are for purposes of reference only, and
shall not limit or otherwise affect any of the terms hereof. The invalidity or
unenforceability of any provision hereof shall in no way affect the validity or
enforceability of any other provision hereof.

      IN WITNESS WHEREOF, the Corporation has executed this Warrant as of the

      by the Corporation on October 18, 2007.

notice in the form attached hereto as Exhibit A (the "Subscription Form") duly
completed and executed and the satisfaction of the surrender and payment
requirements of Section 2, the number of shares of Common Stock of the
Corporation set forth in the Subscription Form, subject to adjustment pursuant
to Section 5.

      1.2   FAIR MARKET VALUE. For purposes hereof, the "Fair Market Value" of a
share of Common Stock as of a particular date (the "Determination Date") shall

      last sale price reported for the twenty (20) trading days immediately
      preceding the Determination Date.

            (b)   If the Corporation's Common Stock is not traded on the TSX but
      is traded on the Nasdaq Global Select Market, Global Market or Capital
      Market (collectively, "Nasdaq"), the American Stock Exchange ("AMEX") or
      another national exchange, the average of the closing or last sale price
      reported for the twenty (20) trading days immediately preceding the
      Determination Date.

      Arbitration Association before a single arbitrator to be chosen from a
      panel of persons qualified by education and training to pass on the matter

      1.3   CORPORATION ACKNOWLEDGMENT. The Corporation will, at the time of the
exercise of the Warrant, upon the request of the Holder acknowledge in writing
its continuing obligation to afford to such Holder any rights to which such
Holder shall continue to be entitled after such exercise in accordance with the
provisions of this Warrant. If the Holder shall fail to make any such request,
such failure shall not affect the continuing obligation of the Corporation to
afford to such Holder any such rights.

      1.4   REGISTRATION RIGHTS. The Holder shall, with respect to the shares of
Common Stock issuable upon exercise of this Warrant, have incidental
registration rights in accordance with the terms of the Registration Rights
Agreement attached to the Subscription Agreement.

      1.5   LEGENDS.

            (a)   Each certificate for Common Stock issued upon exercise of this
      Warrant shall bear the following legend:

      "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED ("U.S. SECURITIES ACT"), OR ANY STATE
      SECURITIES LAWS. THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED,
      SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE ASSIGNED EXCEPT
      PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES
      ACT OR PURSUANT TO AN EXEMPTION THEREFROM. HEDGING TRANSACTIONS INVOLVING
      THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE U.S.
      SECURITIES ACT."

      and

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO
      STOCK EXCHANGE ("TSX"); HOWEVER, THE SAID SECURITIES CANNOT BE TRADED
      THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND
      CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT "GOOD
      DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON TSX."

            (b)   If shares of Common Stock are issued to a Canadian resident
      upon exercise of this Warrant prior to February 19, 2008, each certificate
      for such shares of Common Stock shall, in addition to the legend in
      Section 1.5(a), bear the following legend:

                                       3

<page>

      "UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS
      SECURITY MUST NOT TRADE THE SECURITY BEFORE FEBRUARY 19, 2008."

2.    PROCEDURE FOR EXERCISE.

      2.1   DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. The Corporation
agrees that the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder as the owner of record of such shares
as of the close of business on the date on which the duly completed and executed
Subscription Form, this Warrant Certificate and payment for such shares shall
have been received by the Corporation in accordance herewith. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within five (5) business days thereafter, the Corporation at the
Corporation's expense (including the payment by it of any applicable issue
taxes) will cause to be issued in the name of and delivered to the Holder, or as
such Holder (upon payment by such Holder of any applicable transfer taxes) may
direct in compliance with applicable securities laws, a certificate or
certificates for the number of duly and validly issued, fully paid and
nonassessable shares of Common Stock (or Other Securities) to which such Holder
shall be entitled on such exercise. As to any fraction of a share that the
Holder of one or more Warrants, the rights under which are exercised in the same
transaction, would otherwise be entitled to purchase upon such exercise, the
Corporation shall pay to such Holder an amount in cash equal to such fraction
multiplied by the Fair Market Value of one share of Common Stock on the date of
exercise. Following a partial exercise of this Warrant prior to the Expiration
Date, the Corporation shall cancel this Warrant Certificate and, within five
business days, execute and deliver to the Holder a new Warrant Certificate of
like tenor covering the remaining balance of the shares of Common Stock subject
to this Warrant Certificate.

      2.2   EXERCISE. Payment may be made by certified or official bank check
payable to the order of the Corporation equal to the applicable aggregate
Exercise Price, for the number of Common Shares specified in such Subscription
Form (as such exercise number shall be adjusted to reflect any adjustment in the
total number of shares of Common Stock issuable to the Holder in accordance with
the terms of this Warrant) and the Holder shall thereupon be entitled to receive
the number of duly authorized, validly issued, fully-paid and non-assessable
shares of Common Stock (or Other Securities) determined as provided herein.

      2.3   REPRESENTATION. The Holder of this Warrant has represented to the
Corporation that it is acquiring this Warrant for its own account and not with a
view toward, or for resale in connection with, the public sale or distribution
of this Warrant or the underlying shares of Common Stock, except pursuant to
sales registered or exempted under the Securities Act of 1933, as amended (the
"Securities Act"). The Holder of this Warrant further represented that as of the
Issue Date, the Holder was an "accredited investor" as that term is defined in
Rule 501(a)(3) of Regulation D promulgated by the Securities and Exchange
Commission under the Securities Act. Upon exercise of this Warrant, the Holder
shall, if requested by the Corporation, confirm in writing, in a form
satisfactory to the Corporation, representations concerning the matters
described in this Section 2.3.

3.    EFFECT OF REORGANIZATION, ETC.; ADJUSTMENT OF EXERCISE PRICE.

      3.1   REORGANIZATION, CONSOLIDATION, MERGER, ETC. If at any time or from
time to time, the Corporation (a) effects a reorganization, (b) consolidates
with or merges into any other person, or (c) transfers all or substantially all
of its properties or assets to any other person under any plan or arrangement
contemplating the dissolution of the Corporation, then, in each such case, as a
condition to the consummation of such a transaction, proper and adequate
provision shall be made by the Corporation whereby the Holder of this Warrant,
on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

      3.2   DISSOLUTION. In the event of any dissolution of the Corporation
following the transfer of all or substantially all of its properties or assets,
the Corporation, concurrently with any distributions made to holders of its
Common Stock, shall at its expense deliver or cause to be delivered to the
Holder the stock and other securities and property (including cash, where
applicable) receivable by the Holder of this Warrant pursuant to Section 3.1, or
if the Holder also instructs the Corporation, to a bank or trust company
specified by the Holder as trustee for the Holder (the "Trustee").

      3.3   CONTINUATION OF TERMS. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Corporation, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. If this
Warrant does not continue in full force and effect after the consummation of the
transactions described in this Section 3, then the Corporation's securities and
property (including cash, where applicable) receivable by the Holder of this
Warrant will be delivered to the Holder or the Trustee as contemplated by
Section 3.2.

4.    EXTRAORDINARY EVENTS REGARDING COMMON STOCK. If the Corporation (a) issues
additional shares of the Common Stock as a dividend or other distribution on
outstanding Common Stock or any preferred stock issued by the Corporation, (b)
subdivides its outstanding shares of Common Stock, or (c) combines its
outstanding shares of the Common Stock into a smaller number of shares of the
Common Stock, then, in each such event, the Exercise Price shall, simultaneously
with the happening of such event, be adjusted by multiplying the then Exercise
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such event and the denominator of
which shall be the number of shares of Common Stock outstanding immediately

                                       5

<page>

after such event, and the product so obtained shall thereafter be the Exercise
Price then in effect. The Exercise Price, as so adjusted, shall be readjusted in
the same manner upon the happening of any successive event or events described
herein in this Section 4. The number of shares of Common Stock that the Holder
of this Warrant shall thereafter, on the exercise hereof as provided herein in
Section 1, be entitled to receive shall be adjusted to a number determined by
multiplying the number of shares of Common Stock that would otherwise (but for
the provisions of this Section 4) be issuable on such exercise by a fraction of
which (a) the numerator is the Exercise Price that would otherwise (but for the
provisions of this Section 4) be in effect, and (b) the denominator is the
Exercise Price in effect on the date of such exercise.

5.    CERTIFICATE AS TO ADJUSTMENTS. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrant as provided for in Section 3 or 4 above, the Corporation
at its expense will promptly cause its Chief Financial Officer or other
appropriate designee to compute such adjustment or readjustment in accordance
with the terms of the Warrant and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (a) the
consideration received or receivable by the Corporation for any additional
shares of Common Stock (or Other Securities) issued or sold or deemed to have
been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Corporation will
forthwith mail or cause to be mailed a copy of each such certificate to the
Holder of this Warrant.

6.    RESERVATION OF STOCK, ETC. ISSUABLE ON EXERCISE OF WARRANT. The
Corporation will at all times reserve and keep available, solely for issuance
and delivery on the exercise of this Warrant, shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of this Warrant.

7.    ASSIGNMENT; EXCHANGE OF WARRANT. Subject to compliance with applicable
securities laws, this Warrant, and the rights evidenced hereby, may be
transferred by any registered holder hereof (a "Transferor") in whole or in
part. On the surrender for exchange of this Warrant, with the Transferor's
endorsement in the form of Exhibit B (the "Transferor Endorsement Form"),
together with evidence reasonably satisfactory to the Corporation demonstrating
compliance with applicable securities laws in a manner consistent with the
restrictive legend on this Warrant, the Corporation at the Corporation's expense
(but with payment by the Transferor of any applicable transfer taxes), will
cause to be issued and delivered to or on the order of the Transferor thereof a
new Warrant of like tenor, in the name of the Transferor and/or the
transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
so surrendered by the Transferor.

8.    REPLACEMENT OF WARRANT. On receipt of evidence reasonably satisfactory to
the Corporation of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement and surety bond reasonably satisfactory in
form and amount to the Corporation, the Corporation at the Holder's expense and
Holder's payment of charges of the Corporation, will execute and deliver, in
lieu thereof, a new Warrant of like tenor.

9.    EXERCISE RESTRICTIONS.

      9.1   LIMITATION ON NUMBER OF SHARES ISSUABLE. Notwithstanding anything
contained herein to the contrary, the rights represented by this Warrant shall
not be exercisable by the Holder and the Corporation shall not give effect to
any such exercise, if and solely to the extent that after giving effect to such
exercise, the Holder, together with any person or company acting jointly or in
concert with the Holder with respect to the voting of voting securities of the
Corporation (the "Joint Actors") would in the aggregate directly or indirectly
own or exercise control or direction over the voting of that number of voting
securities of the Corporation (not including shares subject to a warrant as to
which no notice of exercise and corresponding payment has been delivered) that
is 19.99% or greater of the total issued and outstanding voting securities of
the Corporation after giving effect to such exercise.

      9.2   PROVISION OF OFFICER'S CERTIFICATE. Prior to exercising the rights
represented by this Warrant, the Holder shall provide the Corporation with an
officer's certificate stating the number of voting securities of the Corporation
held by the Holder and its Joint Actors, if any, as of the date provided for in
the exercise notice (the "Officer's Certificate") and the Corporation shall be
entitled to rely on the Officer's Certificate in making any determinations
regarding the total issued and outstanding voting securities of the Corporation
to be held by the Holder and its Joint Actors, if any, after giving effect to
the exercise. The execution of the Subscription Form by the Holder will suffice
as the Holder's acknowledgement of compliance with such exercise limits as set
forth in this Section 9.

10.   TRANSFER ON THE CORPORATION'S BOOKS. Until this Warrant is transferred on
the books of the Corporation, the Corporation may treat the registered Holder
hereof as the absolute owner hereof for all purposes, notwithstanding any notice
to the contrary.

11.   NOTICES, ETC. All notices and other communications from the Corporation to
the Holder of this Warrant shall be delivered by ordinary surface or air mail,
postage prepaid, addressed to the Holder or delivered at their respective
address appearing on the register of Holders.

12.   MISCELLANEOUS. Notwithstanding any provision to the contrary contained in
this Warrant, no Common Stock will be issued pursuant to the exercise of this
Warrant if the issuance of such securities may constitute a violation of the
securities laws of any applicable jurisdiction. This Warrant and any term hereof
may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of such change, waiver,
discharge or termination is sought. THIS WARRANT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF STATE OF CALIFORNIA WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION BROUGHT CONCERNING THE TRANSACTIONS
CONTEMPLATED BY THIS WARRANT SHALL BE BROUGHT ONLY IN THE STATE COURTS OF
CALIFORNIA OR IN THE FEDERAL COURTS LOCATED IN THE STATE OF CALIFORNIA. The
Holder and the Corporation shall submit to the jurisdiction of such courts and
waive trial by jury. The prevailing party shall be entitled to recover from the
other party its reasonable attorney's fees and costs. If any provision of this

                                       7

<page>

Warrant is invalid or unenforceable under any applicable statute or rule of law,
then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Warrant. The headings in this Warrant are for purposes of reference
only, and shall not limit or otherwise affect any of the terms hereof. The
invalidity or unenforceability of any provision hereof shall in no way affect
the validity or enforceability of any other provision hereof.

      IN WITNESS WHEREOF, the Corporation has executed this Warrant as of the
date first written above.
