consideration, the receipt and sufficiency of which are hereby acknowledged, _________________________________, the registered
holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below,
to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this Warrant to Purchase
Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”),
at any time or times on or after the date hereof, but not after 11:59 p.m., Delaware time, on the Expiration Date (as defined
below), ______________ (_____________)1 fully paid, validly issued and nonassessable shares (the “Warrant
Shares”) of the Company’s common stock, no par value (the “Common Stock”). This
Warrant is one of the Warrants to Purchase Common Stock issued in connection with the issuance of the Notes pursuant to the Note
Purchase Agreement (the “Note Purchase Agreement”), dated as of August 24, 2012 (the “Initial
Closing Date”), by and among the Company and the investors referred to therein. Except as otherwise defined herein,
capitalized terms in this Warrant shall have the meanings set forth in Section 12. References in this Warrant to “Sections”
shall be to Sections of this Warrant unless otherwise specifically provided.


 


1.          Exercise
of Warrant.


 


(a)          Mechanics
of Exercise. Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder on any day on or after
the date hereof, in whole or in part, by (i) delivery to the Company of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant, (ii) surrender
of this Warrant, and (iii) either (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied by
the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”)
in cash or by wire transfer of immediately available funds, or (B) by notifying the Company that this Warrant is being exercised
pursuant to a Cashless Exercise (as defined in Section 1(e)).


 


(b)          Certificates
for Warrant Shares. The rights under this Warrant shall be deemed to have been exercised and the Warrant Shares issuable upon
such exercise shall be deemed to have been issued immediately prior to the close of business on the date this Warrant is exercised
in accordance with its terms, and the Person entitled to receive the Warrant Shares issuable upon such exercise shall be treated
for all purposes as the holder of record of such Warrant Shares as of the close of business on such date. Upon the exercise of
this Warrant in compliance with the provisions of Section 1(a), the Company shall deliver to the Holder one or more certificates
for the number of Warrant Shares so purchased.


 





 



1 At each Closing, insert an
amount equal to the number of shares of Common Stock into which the Note to which this Warrant is related would be converted if
such Note was to be converted at the time of its issuance at a conversion price equal to $0.40 per share of Common Stock.


 



    	 



    	 



    

 


(c)          Issuance
of Warrant for Balance of Warrant Shares. If this Warrant is submitted in connection with any exercise pursuant to Section
1(a) and the number of Warrant Shares represented by this Warrant is greater than the number of Warrant Shares with respect
to which this Warrant is exercised, then the Company shall as soon as practicable, and in any event within thirty (30) days of
the Exercise Notice, issue a new Warrant (in accordance with Section 4(d)) representing the right 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. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but
rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.


 


(d)          Exercise
Price. For purposes of this Warrant, “Exercise Price” means $0.60 per share, subject to adjustment
as provided herein.


 


(e)          Cashless
Exercise. In lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment
of the Aggregate Exercise Price, the Holder may, in its sole discretion, exercise this Warrant, in whole or in part, and elect
instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following
formula (a “Cashless Exercise”):


 


Net Number = (A x B) - (A x C)


 


B


 


For purposes of the foregoing formula:


 


A= the total number of shares with respect to which
this Warrant is then being exercised;


 


B= the
average of the Weighted Average Price of shares of Common Stock for the ten (10) consecutive Trading Days ending on the date immediately
preceding the date of the Exercise Notice; and


 


C= the Exercise Price then in effect for the applicable
Warrant Shares at the time of such exercise.


 


(f)          Insufficient
Authorized Shares. The Company agrees during the term the rights under this Warrant are exercisable to reserve and keep available
from its authorized and unissued shares of Common Stock solely for the purpose of effecting the exercise of this Warrant such number
of shares as shall from time to time be sufficient to effect the exercise of the rights under this Warrant; and if at any time
the number of authorized but unissued shares of Common Stock shall not be sufficient for purposes of the exercise of this Warrant
in accordance with its terms, the Company will use all reasonable efforts to take such corporate action as may be necessary to
increase its authorized and unissued shares of its Common Stock to a number of shares as shall be sufficient for such purposes.
The Company represents and warrants that all shares that may be issued upon the exercise of this Warrant will, when issued in accordance
with the terms hereof, be validly issued, fully paid and nonassessable.


 


2.          Adjustment
of Exercise Price.


 


(a)          Adjustment
for Stock Splits, Stock Dividends, Etc. If, at any time on or after the date hereof, the number of outstanding shares of Common
Stock is increased by a stock split, stock dividend, reclassification or other similar event, the Exercise Price shall be proportionately
reduced, or if the number of outstanding shares of Common Stock is decreased by a reverse stock split, combination or reclassification
of shares, or other similar event, the Exercise Price shall be proportionately increased.


 



    	2



    	 



    

 


(b)          Adjustment
Due to Merger, Consolidation, Etc. If, at any time after the date hereof, there shall be (i) any reclassification or change
of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), (ii) any consolidation or merger of the Company with any other
entity (other than a merger in which the Company is the surviving or continuing entity and its capital stock is unchanged), (iii)
any sale or transfer of all or substantially all of the assets of the Company, or (iv) any share exchange pursuant to which all
of the outstanding shares of Common Stock are converted into other securities or property (each of (i) - (iv) above being a “Corporate
Change”), then the Holder shall thereafter have the right to receive upon exercise of this Warrant, in lieu of the
shares of Common Stock otherwise issuable, such shares of stock, securities and/or other property as would have been issued or
payable in such Corporate Change with respect to or in exchange for the number of shares of Common Stock which would have been
issuable upon such exercise had such Corporate Change not taken place.


 


(c)          Notice
of Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price pursuant to this Section 2,
the Company shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.


 


3.          Warrant
Holder Not Deemed a Shareholder; Compliance with Securities Laws.


 


(a)          Warrant
Holder Not Deemed a Shareholder. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital
of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in
such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder of the Company or any right to vote,
give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation,
merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to
the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant.
In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities
(upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company
or by creditors of the Company.


 


(b)          Securities
Law Legend. The Warrant Shares shall (unless otherwise permitted by the provisions of this Warrant) be stamped or imprinted
with a legend substantially similar to the following (in addition to any legend required by state securities laws):


 


THE SECURITIES REPRESENTED BY
THIS CERTIFICATE 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 (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT
FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL, IN A FORM REASONABLY ACCEPTABLE
TO THE COMPANY’S LEGAL COUNSEL, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144
OR RULE 144A UNDER SAID ACT.


 


(c)          Instructions
Regarding Transfer Restrictions. The Holder consents to the Company making a notation on its records and giving instructions
to any transfer agent in order to implement the restrictions on transfer established in Section 4(a).


 


(d)          Removal
of Legend. The legend referring to federal and state securities laws identified in Section 3(b) stamped on a certificate
evidencing the Warrant Shares and the stock transfer instructions and record notations with respect to such securities shall be
removed and the Company shall issue a certificate without such legend to the holder of such securities if (i) such securities are
registered under the Securities Act of 1933, as amended, or (ii) such holder provides the Company with an opinion of counsel reasonably
acceptable to the Company’s counsel to the effect that a sale or transfer of such securities may be made without registration
or qualification.

(b)          Lost,
Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
