and prior to 5:00 p.m., Eastern Standard Time, on the Expiration Date by: (i) delivery of a written notice, in the form of the subscription notice attached as Exhibit A hereto or a reasonable facsimile thereof (the “Exercise
Notice”), to the Company and the Company’s designated transfer agent (the “Transfer Agent”), of such holder’s election to exercise all or a portion of this Warrant on a Cashless Exercise basis in accordance with
Section 2(d) hereof, which notice shall specify the number of Warrant Shares to be received upon such Cashless Exercise; and (ii) the surrender of this Warrant to the Company (the items to be delivered pursuant to clauses (i) and (ii) above
collectively are referred to herein as the “Exercise Delivery Documents”); provided, however, that if such Warrant Shares are to be issued in any name other than that of the registered holder of this Warrant, such issuance
shall be deemed a transfer and the provisions of Section 8 of this Warrant shall be applicable. In the event of any exercise of the rights represented by this Warrant in compliance with this Section 2(a), the Company shall, within 3 Business Days
after receipt of the Exercise Delivery Documents, issue and deliver to the address specified in the Exercise Notice, a certificate or certificates in such denominations as may be requested by the holder in the Exercise Notice, registered in the name
of the holder or its designee, for the number of shares of Common Stock to which the holder shall be entitled upon such exercise. Upon delivery of the Exercise Delivery Documents, the holder of this Warrant shall be deemed for all corporate purposes
to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the certificates evidencing such Warrant Shares. 
  
 (b) Unless the rights represented by this Warrant shall have expired or shall
have been fully exercised, the Company shall, within 3 Business Days after receipt of the Exercise Delivery Documents, and at its own expense, issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights
to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. 
  

 3 








 (c) Notwithstanding anything contained in this Warrant to the contrary, the Company shall not be required
to issue fractions of shares of Common Stock upon exercise of this Warrant or to distribute certificates evidencing such fractional shares. If more than one Warrant shall be presented for exercise in full at the same time by the same holder, the
number of full shares of Common Stock shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of shares of Common Stock purchasable on exercise of all Warrants so presented. In lieu of any fractional
shares, there shall be paid to the holder an amount of cash equal to the same fraction of the Current Market Value of a share of Common Stock. For purposes of Sections 2(c) and (d), the Current Market Value of a share of Common Stock shall be the
Trading Price of a share of Common Stock for the Trading Day immediately prior to the date of such exercise. 
  
 (d) The holder upon exercise of the Warrant will receive upon such exercise the “Net Number” of shares of Common Stock determined according to
the following formula (a “Cashless Exercise”): 
  

			
	 X =  
	  	Y x (A - B)
	 	  	A

  
 For purposes of the
foregoing formula: 
  

			
	 X =
	  	the Net Number of shares of Common Stock to be issued to the holder.
		
	 Y =
	  	the number of shares of Common Stock subject to this Warrant for which the Warrant is being exercised.
		
	 A =
	  	the Current Market Value of one share of Common Stock on the date this Warrant is being exercised.
		
	 B =
	  	the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise, as adjusted.

  
 Section 3. Date; Duration. The
issue date of this Warrant is April 22, 2004 (the “Warrant Date”). This Warrant, in all events, shall be wholly void and of no effect at 5:00 pm Eastern Standard Time on the Expiration Date. 
  
 Section 4. Taxes. 
  
 (a) The Company shall pay any and all documentary, stamp, transfer and other similar taxes that may be payable with respect
to the issuance and delivery of Warrant Shares upon exercise of this Warrant. 
  

 4 








 (b) Notwithstanding any other provision of this Warrant, for income tax purposes, the holder or any
assignee or transferee shall agree that the Company and the Transfer Agent shall be permitted to withhold from any amounts payable to such assignee or transferee any taxes required by law to be withheld from such amounts. Unless exempt from the
obligation to do so, each assignee or transferee shall execute and deliver to the Company or the Transfer Agent, as applicable, a properly completed Form W-8 or W-9, indicating that such assignee or transferee is not subject to back-up withholding
for United States federal income tax purposes. Each assignee or transferee that does not deliver such a form pursuant to the preceding sentence shall have the burden of proving to the Company’s reasonable satisfaction that it is exempt from
such requirement. 
  
 (c) The issuance of certificates for shares
of Common Stock upon the exercise of this Warrant shall be made without charge to the holder of this Warrant for any issue tax in respect thereof; provided, however, that the Company shall not be required to pay any tax that may be payable in
respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder hereof, and the Company shall not be required to issue or deliver such certificates or other securities unless and until the
person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise specifically
provided herein, prior to the exercise of the Warrants represented hereby, the holder of this Warrant shall not be entitled, as such, to any rights of a stockholder of the Company, including, without limitation, the right to vote or to consent to
any action of the stockholders of the Company, to receive dividends or other distributions, to exercise any preemptive right or to receive any notice of meetings of stockholders of the Company, and shall not be entitled to receive any notice of any
proceedings of the Company. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on such holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company,
whether such liabilities are asserted by the Company or by creditors of the Company. 
  
 Section 6. Compliance with Securities Laws. 
  
 (a) The holder of this Warrant, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and the Warrant Shares issuable upon exercise of this Warrant for its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the holder does not
agree to hold this Warrant or any of the Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares at any time in accordance with or pursuant to a registration statement or an
exemption under the Securities Act. The holder of this Warrant further represents, by acceptance hereof, that, as of this date, such holder is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D promulgated by
the Securities and Exchange Commission under the Securities Act and was not organized for the specific purpose of acquiring this Warrant or Warrant Shares. 
  

 5 








 (b) This Warrant and all the Warrant Shares issued upon exercise hereof or conversion thereof shall be
stamped or imprinted with a legend in substantially the following form (in addition to any legend required by state securities laws or any securities exchange upon which such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless, in the case of the Warrant Shares, the two-year holding period of the Warrant submitted for exercise has expired: 
  
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE
SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN APPLICABLE EXEMPTION
THEREFROM. 
  
 The legend set forth above shall be removed and the
Company (in the case of Warrants) or the Transfer Agent (in the case of Warrant Shares) shall issue a new Warrant or Warrant(s) of like tenor and aggregate principal amount, or a certificate or certificates representing Warrant Shares, as
appropriate, without such legends to the holder of the Warrant(s) or Warrant Shares upon which they are stamped, (i) if such Warrant Shares are registered for resale under the Securities Act and are transferred or sold pursuant to a registration,
(ii) if, in connection with a sale transaction, such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a public sale, assignment or transfer of the Warrant(s) or Warrant Shares may be made
without registration under the Securities Act and that upon such public sale, assignment or transfer that the Warrants or Warrant Shares are no longer “restricted securities” under the meaning of Rule 144, or (iii) upon expiration of the
two-year period under Rule 144(k) promulgated under the Securities Act (or any successor rule). In the event Rule 144(k) (or any successor rule) is amended to change the two-year period, the reference in the preceding sentence shall be deemed to be
a reference to such changed period, provided that such change shall not become effective if it is otherwise prohibited by, or would otherwise cause a violation of, the then applicable federal securities laws. The Company shall not require such
opinion of counsel for the sale of the Warrant(s) or Warrant Shares in accordance with Rule 144 of the Securities Act, provided the Seller provides such representations that the Company shall reasonably request confirming compliance with the
requirements of Rule 144.

 Section 7. Ownership and Transfer. 
  
 (a) The Company shall maintain at its principal office designated on the first page of this Agreement or such other office
or agency of the Company as it may designate by notice to the holder hereof (provided that such other designated office shall be located in the United States) (a “Designated Office”), a register for this Warrant (the
“Warrant Register”), in which the Company shall record the name and address of the person in whose name this Warrant has been issued. Upon the transfer of any Warrants in accordance with the provisions of clause (b) below, the
Company shall record the name and address of such new holder(s) as well as the name and address of each transferee. The Company may treat the person in whose name any Warrant is registered on the Warrant Register as the owner and holder thereof for
all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant. 
  
 (b) This Warrant and all rights hereunder shall be assignable and transferable by the holder hereof to a Permitted Transferee upon surrender of this
Warrant with a properly executed assignment (in the form of Exhibit B hereto) at the Company’s Designated Office. For the purposes of this Warrant, a “Permitted Transferee” shall mean any person who delivers to the
Company his, her or its written agreement to accept and be bound by all of the terms and conditions contained in this Warrant. 
  
 Section 8. Adjustment of Exercise Price and Number of Shares Issuable Upon Exercise. 
  
 The Exercise Price and the number of Warrant Shares issuable upon the exercise of each Warrant are subject to adjustment
from time to time upon the occurrence of the events enumerated in this Section 9. 
  
 (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Exercise Price in effect at the opening of business on the
date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the record date of this Warrant fixed for such determination and (ii) the denominator shall be the sum of such number of shares and the total number of shares referred to in (i) above constituting
such dividend or other distribution. Such reduction in the Exercise Price shall become effective immediately after the opening of business on the day following the record date. If any dividend or distribution of the type described in this Section
9(a) of this Warrant is declared but not so paid or made, the Exercise Price shall again be adjusted to the Exercise Price that otherwise then be in effect if such dividend or distribution had not been declared. 
  
 (b) In case the outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Exercise Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case the outstanding
shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Exercise Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be 

  

 7 








 
proportionately increased, such reduction or increase, as applicable, to become effective immediately after the opening of business on the day following the
day upon which such subdivision or combination becomes effective. 
  
 (c) The Company may make such reductions in the Exercise Price, in addition to those required by Sections 9(a) or (b) of this Warrant, as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of
Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
  
 (d) No adjustment in the Exercise Price shall be required under this Section
9 unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price; provided, however, that any adjustments which by reason of this Section 9(d) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section 9 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a
change in the no par value of the Common Stock. 
  
 (e) Notice
to Holders of Warrants Prior to Certain Actions. In case: 
  
 (1) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Exercise Price pursuant to this Section 9; 
  
 (2) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding
Common Stock, a change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or combination to which the Company is a party and for which approval of
any stockholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or 
  
 (3) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
  
 the Company shall cause to be provided to the holder of this Warrant at such address appearing in the Warrant Register at least ten (10)
days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the
date as of which the holders of shares of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (y) the date on which such reclassification, merger, consolidation, statutory share exchange,
combination, sale, transfer, conveyance, dissolution, liquidation or winding-up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon such reclassification, merger, consolidation, statutory share exchange, combination, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 9(e). In addition, whenever the Exercise Price is 

  

 8 








 
adjusted as provided in this Section 9, the Company shall prepare a notice of such adjustment of the Exercise Price setting forth the adjusted Exercise Price
and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Exercise Price to the holder of each Warrant at his last address in the Warrant Register within twenty (20) days of the effective date of
such adjustment. Failure to deliver such notice nor any defect therein shall not effect the legality or validity of any such adjustment. 
  
 (f) In any case in which this Section 9 provides that an adjustment shall become effective immediately after a record date for an event, the Company may
defer until the occurrence of such event (i) issuing to the holder of any Warrant exercised after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such exercise by reason of the adjustment
required by such event over and above the Common Stock issuable upon such exercise before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 2(c) of this Warrant.

  
 (g) Upon each adjustment of the Exercise Price pursuant to
this Section 9, each Warrant shall thereupon evidence the right to purchase that number of Warrant Shares (calculated to the nearest hundredth of a share) obtained by multiplying the number of Warrant Shares purchasable immediately prior to such
adjustment upon exercise of the Warrant by the Exercise Price in effect immediately prior to such adjustment and dividing the product so obtained by the Exercise Price in effect immediately after such adjustment. The adjustment pursuant to this
Section 9(g) to the number of Warrant Shares purchasable upon exercise of a Warrant shall be made each time an adjustment of the Exercise Price is made pursuant to this Section 9. 
  
 Section 9. Lost, Stolen, Mutilated or Destroyed Warrants. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall
promptly, on receipt of an indemnification undertaking or other form of security reasonably acceptable to the Company (or in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost,
stolen, mutilated or destroyed. 
  
 Section 10. Notice. All notices,
requests, consents and other communications hereunder shall be in writing, shall be mailed (A) if within United States by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid, or by
