“Company”), hereby certifies that, for value received, LAURUS MASTER FUND, LTD., or assigns (the

replacement of Common Stock or Other Securities pursuant to Section 4 or otherwise.

(e) The term “Purchase Agreement” means the Securities Purchase Agreement dated as of
the date hereof among the Holder and the Company, as amended, modified, restated and/or
supplemented from time to time.

1. Exercise of Warrant.

1.1 Number of Shares Issuable upon Exercise. From and after the date hereof, the
Holder shall be entitled to receive, upon exercise of this Warrant in whole or in part, by delivery
of an original or fax copy of an exercise notice in the form attached hereto as Exhibit A (the
“Exercise Notice”), shares of Common Stock of the Company, subject to adjustment pursuant to
Section 4.

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 mean:

(a) If the Company’s Common Stock is traded on the American Stock Exchange or another
national exchange or is quoted on the National or Capital Market of The Nasdaq Stock Market,
Inc. (“Nasdaq”), then the closing or last sale price, respectively, reported for the last

(c) Except as provided in clause (d) below, if the Company’s Common Stock is not

the charter in the event of such liquidation, dissolution or winding up, plus all other

1.3 Company Acknowledgment. The Company will, at the time of the exercise of this
Warrant, upon the request of the holder hereof 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 Company to afford to
such holder any such rights.

1.4 Trustee for Warrant Holders. In the event that a bank or trust company shall have
been appointed as trustee for the holders of this Warrant pursuant to Subsection 3.2, such bank or
trust company shall have all the powers and duties of a warrant agent (as hereinafter described)
and shall accept, in its own name for the account of the Company or such successor person as may be
entitled thereto, all amounts otherwise payable to the Company or such successor, as the case may
be, on exercise of this Warrant pursuant to this Section 1.

2. Procedure for Exercise.

2.1 Delivery of Stock Certificates, Etc., on Exercise. The Company agrees that the
shares of Common Stock purchased upon exercise of this Warrant shall be deemed to be issued to the
Holder as the record owner of such shares as of the close of business on the date on which this
Warrant shall have been surrendered and payment made for such shares in accordance herewith. As
soon as practicable after the exercise of this Warrant in full or in part, and in any event within
three (3) business days thereafter, the Company at its 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, plus, in lieu of any fractional share to which such
holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market
Value of one full share, together with any other stock or other securities and property (including
cash, where applicable) to which such Holder is entitled upon such exercise pursuant to Section 1
or otherwise.

2.2 Exercise.

(a) Payment may be made either (i) in cash of immediately available funds or by
certified or official bank check payable to the order of the Company equal to the applicable
aggregate Exercise Price, (ii) by delivery of this Warrant, or shares of Common Stock and/or
Common Stock receivable upon exercise of this Warrant in accordance with the formula set
forth in subsection (b) below, or (iii) by a combination of any of the foregoing methods,
for the number of Common Shares specified in such Exercise Notice (as such exercise number
shall be adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the Holder per 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.

 

3

 

(b) Notwithstanding any provisions herein to the contrary, if the Fair Market Value of
one share of Common Stock is greater than the Exercise Price (at the date of calculation as
set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to
receive shares equal to the value (as determined below) of this Warrant (or the portion
thereof being exercised) by surrender of this Warrant at the principal office of the Company
together with the properly endorsed Exercise Notice in which event the Company shall issue
to the Holder a number of shares of Common Stock computed using the following formula:

	 	 	 	 	 
	X=

	 	Y(A-B)
	 	 
	 

	 	 	 	 
	 

	 	A	 	 

	 	 	 
	Where X =

	 	the number of shares of Common Stock to be issued to the Holder
	 
	 	 
	Y =

	 	the number of shares of Common Stock purchasable under this Warrant or, if
only a portion of this Warrant is being exercised, the portion of this Warrant being
exercised (at the date of such calculation)
	 
	 	 
	A =

	 	the Fair Market Value of one share of the Company’s Common Stock (at the date
of such calculation)
	 
	 	 
	B =

	 	the Exercise Price per share (as adjusted to the date of such calculation)

Notwithstanding anything to the contrary set forth in Section 2.2(a) above, to the extent that a
registration statement registering all the shares of Common Stock of the Company issuable upon
exercise of this Warrant has been declared effective by the Securities and Exchange Commission and
remains effective as of the date of the proposed exercise set forth in an Exercise Notice, the
Holder shall upon such proposed exercise, make payment to the Company of each respective Exercise
Price set forth in such Exercise Notice in cash by wire transfer of immediately available funds or
by certified or official bank check only.

3. Effect of Reorganization, Etc.; Adjustment of Exercise Price.

3.1 Reorganization, Consolidation, Merger, Etc. In case at any time or from time to
time, the Company shall (a) effect a reorganization, (b) consolidate with or merge into any other
person, or (c) transfer all or substantially all of its properties or assets to any other person
under any plan or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and adequate provision shall
be made by the Company whereby the Holder, 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.

 

4

 

3.2 Dissolution. In the event of any dissolution of the Company following the
transfer of all or substantially all of its properties or assets, the Company, 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 pursuant to Section 3.1, or, if the Holder shall so instruct
the Company, to a bank or trust company specified by the Holder and having its principal office in
New York, NY as trustee for the Holder.

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 Company, whether or not such person shall have expressly
assumed the terms of this Warrant as provided in Section 4. In the event this Warrant does not
continue in full force and effect after the consummation of the transactions described in this
Section 3, then the Company’s securities and property (including cash, where applicable) receivable
by the Holder will be delivered to the Holder or the Trustee as contemplated by Section 3.2.

4. Extraordinary Events Regarding Common Stock. In the event that the Company shall
(a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding
Common Stock or any preferred stock issued by the Company, (b) subdivide its outstanding shares of
Common Stock, (c) combine its outstanding shares of the Common Stock into a smaller number of
shares of the Common Stock, then, in each such event, the number of shares of Common Stock that the
holder shall thereafter, on the exercise hereof as provided 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 number of any issued and outstanding shares of common
stock immediately after such event that would otherwise (but for the provisions of this Section 4)
be in effect, and (b) the denominator is number of any issued and outstanding shares of common
stock immediately prior to such event. Notwithstanding the foregoing, in no event shall the
Exercise Price be less than the par value of the Common Stock.

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 this Warrant, the
Company 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 this 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 Company 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

 

5

 

(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 Company will forthwith mail a copy of each such
certificate to the holder and any warrant agent of the Company (appointed pursuant to Section 11
hereof).

6. Reservation of Stock, Etc., Issuable on Exercise of Warrant. The Company 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 attached hereto (the “Transferor Endorsement
Form”) and together with evidence reasonably satisfactory to the Company demonstrating compliance
with applicable securities laws, which shall include, without limitation, a legal opinion from the
Transferor’s counsel (at the Company’s expense) that such transfer is exempt from the registration
requirements of applicable securities laws, the Company at its expense (but with payment by the
Transferor of any applicable transfer taxes) will issue and deliver 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
Company 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 or security
reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation,
on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver,
in lieu thereof, a new Warrant of like tenor.

9. Registration Rights. The Holder has been granted certain registration rights by
the Company. These registration rights are set forth in a Registration Rights Agreement entered
into by the Company and Holder dated as of the date hereof, as the same may be amended, modified
and/or supplemented from time to time.

10. Maximum Exercise. Notwithstanding anything herein to the contrary, in no event
shall the Holder be entitled to exercise any portion of this Warrant in excess of that portion of
this Warrant upon exercise of which the sum of (1) the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates (other than shares of Common Stock which may be
deemed beneficially owned through the ownership of the unexercised portion of the Warrant or the
unexercised or unconverted portion of any other security of the Holder subject to a limitation on
conversion analogous to the limitations contained herein) and (2) the number of shares of Common
Stock issuable upon the exercise of the portion of this Warrant with respect to which the
determination of this proviso is being made, would result in beneficial ownership by

 

6

 

the Holder and its Affiliates of any amount greater than 9.99% of the then outstanding shares
of Common Stock (whether or not, at the time of such exercise, the Holder and its Affiliates
beneficially own more than 9.99% of the then outstanding shares of Common Stock). As used herein,
the term “Affiliate” means any person or entity that, directly or indirectly through one or more
intermediaries, controls or is controlled by or is under common control with a person or entity, as
such terms are used in and construed under Rule 144 under the Securities Act. For purposes of the
second preceding sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except
as otherwise provided in clause (1) of such sentence. For any reason at any time, upon written or
oral request of the Holder, the Company shall within one (1) business day confirm orally and in
writing to the Holder the number of shares of Common Stock outstanding as of any given date. The
limitations set forth herein (x) may be waived by the Holder upon provision of no less than
sixty-one (61) days prior notice to the Company and (y) shall automatically become null and void
following notice to the Company upon the occurrence and during the continuance of an Event of
Default (as defined in the Note referred to in the Purchase Agreement).

11. Warrant Agent. The Company may, by written notice to the each Holder of the
Warrant, appoint an agent for the purpose of issuing Common Stock (or Other Securities) on the
exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and
replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such office by such agent.

12. Transfer on the Company’s Books. Until this Warrant is transferred on the books
of the Company, the Company may treat the registered holder hereof as the absolute owner hereof for
all purposes, notwithstanding any notice to the contrary.

13. Rights of Shareholders. No Holder shall be entitled to vote or receive dividends
or be deemed the holder of the shares of Common Stock or any other securities of the Company which
may at any time be issuable upon exercise of this Warrant for any purpose (the “Warrant Shares”),
nor shall anything contained herein be construed to confer upon the Holder, as such, any of the
rights of a shareholder of the Company or any right to vote for the election of directors or upon
any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon the recapitalization, issuance of shares, reclassification of
shares, change of nominal value, consolidation, merger, conveyance or otherwise) or to receive
notice of meetings, or to receive dividends or subscription rights or otherwise, in each case,
until the earlier to occur of (x) the date of actual delivery to Holder (or its designee) of the
Warrant Shares issuable upon the exercise hereof or (y) the third business day following the date
such Warrant Shares first become deliverable to Holder, as provided herein.

14. Sale Limitation. Notwithstanding anything contained herein to the contrary, the
Holder shall not be entitled to sell any shares of Common Stock of the Company received by the
Holder upon the exercise of all or any portion of this Warrant prior to the first anniversary of
the date hereof. The sale limitation described on this Section 14 shall automatically become null
and void without notice to the Company upon the occurrence and during the continuance of an Event
of Default (as defined in the Note).

 

7

 

15. Notices, Etc. All notices and other communications from the Company to the Holder
shall be mailed by first class registered or certified mail, postage prepaid, at such address as
may have been furnished to the Company in writing by such Holder or, until any such Holder
furnishes to the Company an address, then to, and at the address of, the last Holder who has so
furnished an address to the Company.

16. Miscellaneous. 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 THE STATE OF NEW YORK WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION BROUGHT CONCERNING THE TRANSACTIONS CONTEMPLATED BY
THIS WARRANT SHALL BE BROUGHT ONLY IN STATE COURTS OF NEW YORK OR IN THE FEDERAL COURTS LOCATED IN
THE STATE OF NEW YORK; PROVIDED, HOWEVER, THAT THE HOLDER MAY CHOOSE TO WAIVE THIS PROVISION AND
BRING AN ACTION OUTSIDE THE STATE OF NEW YORK. The individuals executing this Warrant on behalf of
the Company agree to 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 attorneys’ fees
and costs. In the event that 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. The Company acknowledges that legal
counsel participated in the preparation of this Warrant and, therefore, stipulates that the rule of
construction that ambiguities are to be resolved against the drafting party shall not be applied in
the interpretation of this Warrant to favor any party against the other party.

with a mailing address at                                         , with full power of substitution, as proxy,
to vote all shares of Common Stock of the Company, now or in the future owned by Laurus to the

without any further action required by any person.

Laurus shall use its best efforts to forward to Proxy Holder within two (2) business days
following Laurus’ receipt thereof, at the address for Proxy Holder set forth above, copies of all

liabilities owing by the Company to Laurus (as the same may be amended, restated, extended or
modified from time to time).

IN WITNESS WHEREOF, the undersigned has executed this irrevocable proxy as of the 12th day of
April 2007.
