Exhibit 4.2

UNILIFE CORPORATION

WARRANT TO PURCHASE COMMON STOCK

Warrant No.: C02

Date of Issuance: February 11, 2013 (“Issuance Date”)

Unilife Corporation, a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, WESTOR CAPITAL GROUP, INC., 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 exercise 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 Issuance Date but not after 11:59 p.m., New York time, on the Expiration Date, 100,000 (subject to adjustment as provided herein) fully paid and non-assessable shares of Common Stock (as defined below) (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 16.

This Warrant was initially issued to the Westor Capital Group, Inc. (“Westor”) as part of the fee paid to Westor for serving as placement agent in connection with the offering and sale of securities pursuant to that certain Securities Purchase Agreement, dated as of February 11, 2013, by and among the Company and the investor(s) thereunder (the “Buyer” or “Buyers” as applicable) referred to therein (the “Securities Purchase Agreement”).

1. EXERCISE OF WARRANT.

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder on any day on or after the Issuance Date in whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”) along with payment to the Company of an amount equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so exercised (in respect of such specific exercise, the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds if the Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original of this Warrant certificate and issuance of a new Warrant certificate evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the original of this Warrant certificate after delivery of the Warrant Shares in accordance with the terms hereof. On or before the first Trading Day following the date on which the Company has received an Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of such Exercise Notice and Aggregate Exercise Price, in the form attached hereto as Exhibit C, to the Holder and the Company’s

transfer agent (the “Transfer Agent”). On or before the third Trading Day following the date on which the Company has received such Exercise Notice and the Aggregate Exercise Price, the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program (which the Company shall cause the Transfer Agent to do at Holder’s request), upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the Holder or, at the Holder’s instruction pursuant to the Exercise Notice, the Holder’s agent or designee, in each case, sent by reputable overnight courier to the address as specified in the applicable Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice), for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of an Exercise Notice and the Aggregate Exercise Price, the Holder 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 such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then, at the request of the Holder and upon surrender hereof by the Holder at the principal office of the Company, the Company shall as soon as practicable and in no event later than three Trading Days after any exercise and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(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 down to the nearest whole number. The Company shall pay any and all taxes and fees which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. Notwithstanding anything to the contrary contained in this Warrant, all Warrant Shares shall be delivered via DWAC.

(b) Exercise Price. For purposes of this Warrant, “Exercise Price” means $3.00, subject to adjustment as provided herein.

(c) Company’s Failure to Timely Deliver Securities. If the Aggregate Exercise Price has been delivered to the Company and the Company shall fail, for no reason of its own and despite using reasonable best efforts, to issue (or cause to be issued) to the Holder within three Trading Days after receipt of the applicable Exercise Notice (and the Aggregate Exercise Price) or Exchange Notice, as applicable, a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may be), then, in addition to all other remedies available to the Holder, the Company shall pay in cash to the Holder on each day after such third Trading Day that the issuance of such shares of Common Stock is not timely effected an amount equal to 2% of the product of (A) the

aggregate number of shares of Common Stock not issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the last possible date on which the Company could have issued such shares of Common Stock to the Holder without violating Section 1(a). In addition to the foregoing, if within three Trading Days after the Company’s receipt of the applicable Exercise Notice or Exchange Notice, as applicable, the Company shall fail to issue and deliver a certificate to the Holder and register such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise or exchange hereunder (as the case may be), and if on or after such third (3^rd) Trading Day the Holder (or any other Person in respect, or on behalf, of the Holder) purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, issuable upon such exercise or exchange that the Holder so anticipated receiving from the Company, then, in addition to all other remedies available to the Holder, the Company shall, within three Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise or exchange hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise or exchange hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Exercise Notice or Exchange Notice, as the case may be, and ending on the date of such issuance and payment under this clause (ii).

(d) Cashless Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if at the time of an exercise hereof any Equity Conditions Failure shall then exist, then the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, 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, elect instead to make a cashless exercise (each a “Cashless Exercise”) under this Section 1(d). A Cashless Exercise under this Section 1(d) may be made, at the election of the Holder from time to time and irrespective of any other election to make a Cashless Exercise, so that upon such exercise Holder shall receive the “Net Number” of shares of Common Stock determined according to the following formula:

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

B

For purposes of the foregoing formula:

(e) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof (including, without limitation, the Net Number), the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed, provided that following such issuance to Holder such dispute shall be resolved in accordance with Section 13.

(f) Limitations on Exercises and Exchanges. Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable or exchangeable by the Holder hereof to the extent (but only to the extent) that the Holder or any of its affiliates would beneficially own in excess of 9.9% (the “Maximum Percentage”) of the Common Stock following such exercise. To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable or exchangeable (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities shall be exercisable or exchangeable (as among all such securities owned by the Holder) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to exercise or exchange this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability or exchangeability. For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the 1934 Act (as defined in the Securities Purchase Agreement) and the rules and regulations promulgated thereunder. The provisions of this paragraph shall be implemented in a manner otherwise than in

strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. For any reason at any time, upon the written or oral request of the Holder, the Company shall within three Business Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise or exchange of convertible or exercisable or exchangeable securities into Common Stock, including, without limitation, pursuant to this Warrant or securities issued pursuant to the Securities Purchase Agreement.

(g) [Reserved]

(h) Insufficient Authorized Shares. The Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock hereunder (without regard to any limitation otherwise contained herein with respect to the number of shares of Common Stock that may be acquirable upon exercise or exchange of this Warrant). If, notwithstanding the foregoing, and not in limitation thereof, at any time while any of the Warrants remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise or exchange of the Warrants at least a number of shares of Common Stock equal to the number of shares of Common Stock as shall from time to time be necessary to effect the exercise or exchange of all of the Warrants then outstanding (the “Required Reserve Amount”) (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for all the Warrants then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its shareholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each shareholder with a proxy statement and shall use its reasonable efforts to solicit its shareholders’ approval of such increase in authorized shares of Common Stock.

(i) Activity Restrictions. (i) For so long as Holder or any of its Affiliates holds any Warrants or any Warrant Shares, neither Holder nor any Affiliate will: (i) vote any shares of Common Stock beneficially owned by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions, plans or proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in Buyer or its Affiliates beneficially owning (within the meaning of Section 13(d) under the 1934 Act) more than 9.9% of the Common Stock, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its Subsidiaries, (c) a sale or transfer

of a material amount of assets of the Company or any of its Subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure, including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940, (g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees, agents or representatives to amend or waive any provision of this paragraph. The restrictions contained in this paragraph (i) shall not limit Holder’s rights to enforce its rights or exercise its rights as to the Securities or under this Warrant or the Transaction Documents.

(ii) Provided that the Company is in compliance with its obligations under this Warrant and the other Transaction Documents and no Equity Condition Failure shall have occurred, if the trading price on the Principal Market at the time of an exercise of this Warrant is greater than the then applicable Exercise Price then in effect, then in respect of such particular exercise Holder may only exercise this Warrant for a cash exercise price (and not by means of a Cashless Exercise under Section 1(d) above).

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.

(a) Stock Dividends and Splits. Without limiting any provision of Section 3, if the Company, at any time on or after the date of the Securities Purchase Agreement, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.

(b) Return of capital. In a return of capital the number of Warrants must remain the same, and the Exercise Price of each Warrant must be reduced by the same amount as the amount of cash or value of shares, securities, or other property returned in relation to each share of Common Stock.

(c) Reduction of capital. In a reduction of capital by a cancellation of paid up capital that is lost or not represented by available assets where no securities are cancelled – the number of Warrant Shares and the Exercise Price of each Warrant must remain unaltered.

(d) Pro-rata cancellation of capital. In a pro-rata cancellation of capital the number of Warrant Shares must be reduced in the same ratio as outstanding shares of Common Stock on issue and the Exercise Price of each Warrant must be amended in inverse proportion to that ratio.

(e) Bonus shares and stock dividends. If there is a pro-rata bonus issue, or a pro-rata dividend to be paid only in shares of Common Stock, to the holders of outstanding shares of Common Stock, the number of Warrant Shares to be issued upon exercise of the Warrants will be increased by the number of Warrant Shares which the holder of the Warrants would have received if the Warrants had been exercised before the record date for the bonus issue or dividend.

(f) Pro-rata issue. The Warrant does not confer a right to participate in new issues of Common Stock unless the Holder has first exercised the Warrant and such exercise took place on or before the record date for determining entitlements to the issue. A Holder has the right to exercise their Warrant prior to the date for determining entitlements to participate in any issues made during the term of the Warrant, and will be granted a period of at least five Business Days before the relevant record date to exercise the Warrant. In the event that a pro rata issue of the Common Stock (other than a bonus issue) is made to the Company’s stockholders, the Exercise Price of the Warrant shall be reduced in accordance with the formula in ASX Listing Rule 6.22.2.

(g) Notice of Adjustment. Upon any adjustment of the Exercise Price, and/or any increase or decrease in the number of Warrant Shares, the Company shall give written notice thereof to the Holder of the Warrant at the last address of the Holder herein. The notice, shall state the Exercise Price resulting from such adjustment and the increase or decrease, if any, in the number of Warrant Shares, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

(h) In any other case. The number of Warrant Shares or the Exercise Price, or both, must be reorganized so that the holder of the Warrant will not receive a benefit that holders of the Company’s outstanding shares of Common Stock do not receive.

(i) [Reserved]

(j) Calculations. All calculations under this Section 2 shall be made by rounding to the nearest 1/10000^th of cent and the nearest 1/100^th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

3. FUNDAMENTAL TRANSACTIONS.

(a) Fundamental Transactions. If any liquidation, capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another entity in which the Company is not the surviving corporation, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another entity shall be effected (any such transaction being hereinafter referred to as a “Fundamental Transaction”), then this Warrant shall be deemed to be exercised in full immediately upon the closing of such Fundamental Transaction (without the payment of any consideration by the Holder) and the Holder shall thereafter have the right to receive in lieu of the Warrant Shares issuable upon such exercise of this Warrant, such shares of stock, securities or assets (including cash) as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of this Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place.

(b) Black Scholes Value—FT. Notwithstanding the foregoing and the provisions of Section 3(a), at the request of the Holder at any time prior to the closing of a Fundamental Transaction, the Company shall, at of the time of closing of the Fundamental Transaction, purchase this Warrant from the Holder on the date of the consummation of such Fundamental Transaction by paying to the Holder cash in an amount equal to the Black Scholes Value—FT.

4. [Reserved]

5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Warrants are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the Warrants, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Warrants then outstanding (without regard to any limitations on exercise).

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. The Holder, solely in its 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 its capacity as the Holder of this Warrant, any of the rights of a stockholder 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 it 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 stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

7. REISSUANCE OF WARRANTS.

(a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

(b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

(c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for fractional shares of Common Stock shall be given.

(d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

8. NOTICES. Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with the notice provision of the of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant. Without limiting the generality of the foregoing, the Company will give written notice to the Holder as soon as practicable upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s). To the extent that any notice provided hereunder (whether under this Section 8 or otherwise) constitutes, or contains, material, non-public information regarding the Company or any of its Subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement) pursuant to a Current Report on Form 8-K. It is expressly understood and agreed that the time of execution specified by the Holder in each Exercise Notice shall be definitive and may not be disputed or challenged by the Company.

9. AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant (other than Section 1(f)) may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

10. SEVERABILITY. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

11. GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees

not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

12. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents shall have the meanings ascribed to such terms on the Closing Date (as defined in the Securities Purchase Agreement) in such other Transaction Documents unless otherwise consented to in writing by the Holder.

13. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price, the Exchange Amount, the Exchange Price, the Closing Sale Price, the Closing Bid Price, the Bid Price or fair market value or the arithmetic calculation of the Warrant Shares (as the case may be), the Company or the Holder (as the case may be) shall submit the disputed determinations or arithmetic calculations (as the case may be) via facsimile (i) within two Business Days after receipt of the applicable notice giving rise to such dispute to the Company or the Holder (as the case may be) or (ii) if no notice gave rise to such dispute, at any time after the Holder or the Company (as the case may be) learned of the circumstances giving rise to such dispute. If the Holder and the Company are unable to agree upon such determination or calculation (as the case may be) of the Exercise Price, the Exchange Amount, the Exchange Price, the Closing Sale Price, the Closing Bid Price, the Bid Price or fair market value or the number of Warrant Shares (as the case may be) within three Business Days of such disputed determination or arithmetic calculation being submitted to the Company or the Holder (as the case may be), then the Company shall, within two Business Days submit via facsimile (a) the disputed arithmetic calculation of the Warrant Shares, the disputed determination of the Exercise Price, the Exchange Amount, the Exchange Price, the Closing Sale Price, the Closing Bid Price, the Bid Price or fair market value (as the case may be) to an independent, reputable investment bank selected by the Holder or (b) if acceptable to the Holder, the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant (as the case may be) to perform the determinations or calculations (as the case may be) and notify the Company and the Holder of the results no later than ten Business Days from the time it receives such disputed determinations or calculations (as the case may be). Such investment bank’s or accountant’s determination or calculation (as the case may be) shall be binding upon all parties absent demonstrable error.

14. REMEDIES, CHARACTERIZATION, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Warrant. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant may be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. Except where such information and documentation contains or would otherwise constitute material, non-public information, the Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.

15. TRANSFER. This Warrant may be offered for sale, sold, transferred or assigned without the consent of the Company.

The Company may exercise its right to require exercise under this Section 17 (the “Mandatory Exercise Right”) (to the extent permitted hereby) by delivering, within 10 Trading Days following the end of the Trigger Period, a written notice thereof by facsimile and overnight courier to the Holder (the “Mandatory Exercise Notice” and the date such notice by facsimile is deemed to be delivered in accordance with Section 8 is referred to as the “Mandatory Exercise Notice Date”). The Mandatory Exercise Notice shall be irrevocable. The Mandatory Exercise Notice shall (1) state the Trading Day selected for the Mandatory Exercise in accordance with this Section 17, which Trading Day shall be at least five Trading Days but not more than 15 Trading Days following the Mandatory Exercise Notice Date (the “Mandatory Exercise Date”),

(2) state the number of shares of Common Stock to be issued to the Holder on the Mandatory Exercise Date and (3) contain a certification from the Chief Executive Officer of the Company that there has been no Equity Conditions Failure as of the Mandatory Exercise Notice Date. Any portion of this Warrant exercised by the Holder after the Mandatory Exercise Notice Date shall reduce the number of Warrant Shares for which this Warrant is required to be exercised on the Mandatory Exercise Date. If the Company has elected a Mandatory Exercise, the mechanics of exercise set forth in Section 1 shall apply, to the extent applicable, as if the Company had received from the Holder on the Mandatory Exercise Date an Exercise Notice with respect to all of the then-remaining Warrant Shares (or the Permitted Exercise Amount (as defined below) of Warrant Shares, as applicable). Notwithstanding anything contained in this Section 17 to the contrary (but subject to the last sentence of this Section 17), if (I) the Closing Bid Price of the Common Stock on any Trading Day during the period commencing on the Mandatory Exercise Notice Date and ending on the Trading Day immediately preceding the Mandatory Exercise Date is less than the Exercise Price then in effect at the end of trading on such day; (II) the daily dollar trading volume (as reported on Bloomberg) of the Common Stock on the applicable Eligible Market on any Trading Day during the period commencing on the Mandatory Exercise Notice Date and ending on the Trading Day immediately preceding the Mandatory Exercise Date is less than $600,000; or (III) an Equity Conditions Failure occurs on any day since the occurrence of the Trigger Period and is continuing on the Mandatory Exercise Date, then the Mandatory Exercise Notice delivered to the Holder shall be null and void ab initio and the Mandatory Exercise shall not occur and the Mandatory Exercise Right shall not be available to the Company unless and until the conditions precedent to such Mandatory Exercise Right are again satisfied. If the Company elects to cause a mandatory exercise of this Warrant pursuant to this Section 17, then it must simultaneously take the same action with respect to all of the other Warrants, if any, held by any person other than Holder. Notwithstanding anything contained in this Section 17 to the contrary, an effort by the Company to exercise its right under this Section 17 shall be stayed to the extent the Holder delivers a written notice to the Company stating that such exercise would result in a violation of Section 1(f) (a “Blocker Notice”), which Blocker Notice may be delivered at any time prior to the Mandatory Exercise Date, in which case the Company shall have the right to require the Holder to exercise this Warrant for such number of Warrant Shares that may be exercise hereunder without violating Section 1(f) (the “Permitted Exercise Amount”) and from time to time thereafter the Holder shall exercise this Warrant (so long as no Equity Conditions Failure has occurred from and after the Mandatory Exercise Notice Date) in such amounts and from time to time until fully exercised, subject to ongoing compliance with Section 1(f) and subject to Holder’s rights hereunder and the other terms and conditions hereof following the Mandatory Exercise Date
