(f) “Warrant Shares” means the shares of Common Stock issuable upon exercise of the Warrants.

Section 2. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with the terms and conditions set forth herein, and the Warrant Agent hereby accepts such appointment. The Company may from time to time appoint such Co-Warrant Agents as it may, in its sole discretion, deem necessary or desirable.

(a) The Warrants shall be issuable in book entry form. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Warrant Agent or its nominee for each Warrant or (ii) institutions that have accounts with the Warrant Agent (such institution, with respect to a Warrant in its account, a “Participant”).

(b) If the Warrant Agent subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for book-entry settlement or may instruct the Warrant Agent to deliver to each Holder a Warrant Certificate in a form to be mutually agreed upon by the parties.

Section 4. Terms and Conditions of Warrants. The terms and conditions of the Warrants are set forth in Exhibit A hereto (the “Terms and Conditions”).

Section 5. Transfer of Warrants. A Holder of a Warrant may transfer or assign its Warrant pursuant to the Terms and Conditions upon delivery of notice (duly executed by such Holder or its agent or attorney) and funds sufficient to pay any transfer taxes payable upon the making of such transfer to the Warrant Agent at the principal office of the Warrant Agent in Brooklyn, NY, or to the office of one of its agents as may be designated in writing by the Warrant Agent. If any such notice is delivered to the Company, the Company will forward the notice to the Warrant Agent.

Section 6. Registration. The Warrant Agent will keep or cause to be kept, at its office in Brooklyn, NY, or at the office of one of its agents, books for registration and transfer of the Warrants issued hereunder. Such books shall show the names and addresses of the respective Holders of the Warrants, the number of Warrants held by each Holder, and the date on which the Warrant was granted to such Holder. The Warrant Agent will create a special account for the issuance of the Warrants.

(a) Subject to the Terms and Conditions, the Holder of a Warrant may exercise the Warrant, other than by cashless exercise, at any time in whole or in part, at the option of the Holder, upon delivery of an executed Exercise Notice and payment of the Exercise Price, which may be made, at the option of the Holder, by cash delivered to the Warrant Agent at the principal office of the Warrant Agent in Brooklyn, NY or to the office of one of its agents as may be designated in writing by the Warrant Agent, or by wire transfer of funds to the account of the Warrant Agent set forth on Schedule A hereto. Only if then permitted by the Terms and Conditions, the Holder of a Warrant may exercise the Warrant by cashless exercise, in whole or in part, upon delivery of an executed Exercise Notice to the Company. Upon receipt of an Exercise Notice for a cashless exercise, the Company shall calculate and transmit to the Warrant Agent within one (1) Business Day (and the Warrant Agent shall have no obligation under this section to calculate) the number of Warrant Shares issuable in connection with the cashless exercise (the “Cashless Exercise Notification”).

(b) Upon receipt by the Warrant Agent of the Exercise Notice and the Exercise Price as described in Section 7(a) above, or the Cashless Exercise Notification from the Company, the Warrant Agent shall use reasonable efforts to cause to be delivered the Warrant Shares to or upon the order of the Holder of such Warrant, registered in such name or names as may be designated by such Holder by (x) in the event of a cash exercise, the date that is three (3) Business Days after the latest of (A) the delivery to the Warrant Agent of the properly executed and completed Exercise Notice, and (B) payment of the Exercise Price and other amounts as set forth in such Exercise Notice or in the Terms and Conditions or (y) in the event of a cashless exercise, the date that is two (2) Business Days after the delivery to the Warrant Agent by the Company of the Cashless Exercise Notification (each such date, the “Warrant Share Delivery Date”); provided, however, that the Warrant Agent shall not be liable to the Company or the Holder for any damages arising out of the failure to deliver the Warrant Shares by the Warrant Share Delivery Date to the extent that such failure relates to the acts or omissions of the Company, a Holder or a Holder’s prime broker. Notwithstanding the foregoing, if the Company is then a participant in the Deposit Withdrawal at Custodian (“DWAC”) system of the Depository Trust Company (the “Depository”) and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to and resale of the Warrant Shares by Holder or (B) the Warrant is being exercised via cashless exercise pursuant to the Terms and Conditions, the certificates for Warrant Shares shall be transmitted by the Warrant Agent to the Holder by crediting the account of the Holder’s prime broker with the Depository through its DWAC system to the extent the Holder arranges with its broker to initiate delivery through the DWAC system and the Warrant Agent has been duly instructed to deliver the Warrant Shares through the DWAC system.

Section 8. Certain Representations; Reservation and Availability of Shares of Common Stock.

(a) This Agreement has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery hereof by the Warrant Agent, constitutes a valid and legally binding obligation of the Company enforceable against the

Company in accordance with its terms, and the Warrants and the Warrant Shares upon issuance have been duly authorized, executed and issued by the Company and, assuming due authentication thereof by the Warrant Agent pursuant hereto, constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms and entitled to the benefits hereof; in each case except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally or by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(b) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of Common Stock or its authorized and issued shares of Common Stock held in its treasury, free from preemptive rights, the number of shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.

Section 9. Common Stock Record Date. Each person in whose name any certificate for shares of Common Stock is issued (or to whose prime broker’s account is credited shares of Common Stock through the DWAC system) upon the exercise of Warrants shall for all purposes be deemed to have become the holder of record for the Common Stock represented thereby on, and such certificate shall be dated, (x) in the event of a cashless exercise, the date on which the Company receives the Cashless Exercise Notice or (y) in the event of an exercise for cash, the later of (A) the date on which the Warrant Agent receives such Exercise Notice or (B) the date on which the Warrant Agent receives the Exercise Price; provided, however, that if the date of such submission, payment and submission is a date upon which the Common Stock transfer books of the Company are closed, such person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding day on which the Common Stock transfer books of the Company are open.

Section 10. Adjustment of Exercise Price, Number of Shares of Common Stock or Number of Warrants. The Exercise Price, the number of shares covered by each Warrant and the number of Warrants outstanding are subject to adjustment from time to time as provided in the Terms and Conditions.

Whenever the Exercise Price or the number of shares of Common Stock issuable upon the exercise of each Warrant is adjusted as provided in the Terms and Conditions, the Company shall (a) promptly prepare a certificate setting forth the Exercise Price of each Warrant as so adjusted, and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Warrant Agent a copy of such certificate and (c) instruct the Warrant Agent to mail such certificate to each holder of a Warrant.

Section 12. Reclassification, Consolidation, Purchase, Combination, Sale or Conveyance. If, at any time while the Warrants are outstanding, the Company shall effect any Fundamental Transaction, as such term is used in the Terms and Conditions, the Company shall instruct the Warrant Agent to mail by first class mail, postage prepaid, to each Holder of a Warrant, written notice of the execution of any such amendment, supplement or agreement. Any

supplemented or amended agreement entered into by the successor corporation or transferee shall provide for adjustments as set forth in the Terms and Conditions. The Warrant Agent shall be under no responsibility to determine the correctness of any provisions contained in such agreement relating either to the kind or amount of securities or other property receivable upon exercise of warrants or with respect to the method employed and provided therein for any adjustments and shall be entitled to rely upon the provisions contained in any such agreement. The provisions of this Section 12 shall similarly apply to successive Fundamental Transactions.

(a) The Company agrees to pay to the Warrant Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Warrant Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder.

(b) The Company covenants and agrees to indemnify and to hold the Warrant Agent harmless against any costs, expenses (including reasonable fees of its legal counsel), losses or damages, which may be paid, incurred or suffered by or to which it may become subject, arising from or out of, directly or indirectly, any claims or liability resulting from its actions as Warrant Agent pursuant hereto; provided, that such covenant and agreement does not extend to, and the Warrant Agent shall not be indemnified with respect to, such costs, expenses, losses and damages incurred or suffered by the Warrant Agent as a result of, or arising out of, its breach of this Agreement or the Warrant Agent’s gross negligence, bad faith, or willful misconduct.

(c) Promptly after the receipt by the Warrant Agent of notice of any demand or claim or the commencement of any action, suit, proceeding or investigation, the Warrant Agent shall, if a claim in respect thereof is to be made against the Company, notify the Company thereof in writing. The Company shall be entitled to participate at its own expense in the defense of any such claim or proceeding, and, if it so elects at any time after receipt of such notice, it may assume the defense of any suit brought to enforce any such claim or of any other legal action or proceeding. For the purposes of this Section 13, the terms “expense” or “loss” mean any amount paid or payable to satisfy any claim, demand, action, suit or proceeding, and all reasonable costs and expenses, including, but not limited to, reasonable counsel fees and disbursements, paid or incurred in investigating or defending against any such claim, demand, action, suit, proceeding or investigation.

(d) The Warrant Agent shall be responsible for any and all losses, damages, costs, charges, counsel fees, payments, expenses and liability (collectively, “Losses”), and shall indemnify and hold the Company harmless from and against such Losses, arising out of or attributable to the Warrant Agent’s breach of Section 7(b) of this Agreement.

(e) Promptly after the receipt by the Company of notice of any demand or claim or the commencement of any action, suit, proceeding or investigation, the Company shall, if a claim in respect thereof is to be made against the Warrant Agent, notify the Warrant Agent

thereof in writing. The Warrant Agent shall be entitled to participate at its own expense in the defense of any such claim or proceeding, and, if it so elects at any time after receipt of such notice, it may assume the defense of any suit brought to enforce any such claim or of any other legal action or proceeding.

Section 14. Purchase or Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent or any successor Warrant Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent or any successor Warrant Agent shall be party, or any corporation succeeding to the business of the Warrant Agent or any successor Warrant Agent, shall be the successor to the Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under the provisions of Section 13.

Section 15. Duties of Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the Holders of Warrants, by their acceptance thereof, shall be bound:

(a) The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken or omitted by it in good faith and in accordance with such opinion.

(b) Whenever in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by written (including electronic) instructions of the Chief Executive Officer or President of the Company or by the Chief Financial Officer of the Company and delivered to the Warrant Agent; and such certificate shall be full authentication to the Warrant Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such writing.

(c) The Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the Terms and Conditions or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only.

(d) The Warrant Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Warrant Agent); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in the Terms and Conditions; nor shall it be responsible for the adjustment of the Exercise Price or the making of any change in the number of shares of Common Stock or Warrant Shares required under the provisions of Section 7, Section 10, Section 12 and the Terms and Conditions or responsible for the manner, method or

amount of any such change or the ascertaining of the existence of facts that would require any such adjustment or change (except with respect to the exercise of Warrants after actual notice of any adjustment of the Exercise Price); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or as to whether any shares of Common Stock will, when issued, be duly authorized, validly issued, fully paid and nonassessable.

(e) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing by the Warrant Agent of the provisions of this Agreement.

(f) The Warrant Agent is hereby authorized to accept instructions with respect to the performance of its duties hereunder from the Chief Executive Officer, the President, the principal financial officer or the Chief Legal Officer of the Company, and to apply to such officers for advice or instructions in connection with its duties, and it shall not be liable and shall be indemnified and held harmless for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer, provided Warrant Agent carries out such instructions without gross negligence, bad faith or willful misconduct.

(g) The Warrant Agent and any shareholder, director, officer, manager, member or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.

(h) The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

Section 16. Change of Warrant Agent. The Warrant Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Warrants. The Company may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, mailed to the Warrant Agent or successor Warrant Agent, as the case may be, and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Warrants by first-class mail. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the

Holder of a Warrant, then the Holder of any Warrant may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or of a state thereof, in good standing. After appointment, the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer to the successor Warrant Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Warrant Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing to the Holders of the Warrants. However, failure to give any notice provided for in this Section 16, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the successor Warrant Agent, as the case may be.

Section 17. Warrant Exercise Solicitation. From time to time, the Company may engage one or more registered broker-dealer(s) to act as the Company’s agent for the solicitation of the exercise of the Warrants. If so engaged, the Company will provide the Warrant Agent with written notice of the engagement and the Warrant Agent agrees that it will reasonably cooperate with such solicitation activities.

Section 18. Notices. Notices or demands authorized by this Agreement to be given or made (i) by the Warrant Agent or by the Holder of any Warrant to or on the Company, (ii) subject to the provisions of Section 18, by the Company or by the Holder of any Warrant to or on the Warrant Agent or (iii) by the Company or the Warrant Agent to the Holder of any Warrant Certificate, shall be deemed given (w) the date of transmission, if such notice or communication is delivered via facsimile or email at the number or email address set forth below prior to 5:00 p.m. (New York time) on a Business Day, (x) on the date delivered, if delivered personally, (y) on the first Business Day following the deposit thereof with Federal Express or another recognized overnight courier, if sent by Federal Express or another recognized overnight courier, and (z) on the fourth Business Day following the mailing thereof with postage prepaid, if mailed by registered or certified mail (return receipt requested), in each case to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):

If to the Holder of any Warrant, to the address of such holder as shown on the registry books of the Company. Any notice required to be delivered by the Company to the Holder of any Warrant may be given by the Warrant Agent on behalf of the Company.

(a) The Company and the Warrant Agent may from time to time supplement or amend this Agreement without the approval of any Holders of Warrant Certificates in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or inconsistent with any other provisions herein, or to make any other provisions with regard to matters or questions arising hereunder which the Company and the Warrant Agent may deem necessary or desirable and which shall not adversely affect the interests of the Holders of Warrants.

(b) In addition to the foregoing, with the consent of Holders of Warrants entitled, upon exercise thereof, to receive not less than a majority of the shares of Warrant Shares issuable thereunder, the Company and the Warrant Agent may modify this Agreement for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Warrant Agreement or modifying in any manner the rights of the holders of the Warrants; provided, however, that no modification of the terms (including but not limited to the adjustments described in Section 11) upon which the Warrants are exercisable or reducing the percentage required for consent to modification of this Agreement may be made without the consent of the holder of each outstanding warrant certificate affected thereby.

Section 20. Successors. All covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant Agent shall bind and inure to the benefit of their respective successors and assigns hereunder.

Section 21. Benefits of this Agreement. Nothing in this Agreement shall be construed to give any Person other than the Company and the Warrant Agent any legal or equitable right, remedy or claim under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Warrant Agent and the Holders of the Warrants.

Section 22. Governing Law. This Agreement and each Warrant Certificate issued hereunder shall be governed by, and construed in accordance with, the laws of the State of New York without giving effect to the conflicts of law principles thereof.

Section 23. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

Section 24. Captions. The captions of the sections of this Agreement have been inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof.

Section 25. Force Majeure. Notwithstanding anything to the contrary contained herein, neither Warrant Agent nor the Company shall be liable for, or considered to be in breach of or default under this Agreement (including Section 13) on account of any delay or failure to perform its obligations hereunder due to causes beyond such party’s reasonable control including, without limitation, acts of God, terrorist acts, shortage of supply, breakdowns or malfunctions, interruptions or malfunction of computer facilities, or loss of data due to power failures or mechanical difficulties with information storage or retrieval systems, labor difficulties, war, or civil unrest.

Title:

Amedica Corporation, a Delaware corporation (the “Company”), hereby certifies that, for good and valuable 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 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 (as defined below), [5 YEARS FROM ISSUANCE DATE] (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 is one of the Warrants to Purchase Common Stock (the “Purchased Warrants”) issued pursuant to the Offering (as defined in that certain Underwriting Agreement, dated as of November [ ], 2014, by and between the Company and Dawson James Securities, Inc., as representative of the several underwriters (the “Underwriting Agreement”)) consummated on the Issuance Date.

This Warrant shall be issuable in book entry form (the “Book-Entry Warrant Certificate”) and shall initially be represented by one or more Book-Entry Warrant Certificates deposited with American Stock Transfer and Trust Company (the “Warrant Agent”) and registered in the name of the Holder, or as otherwise directed by the Warrant Agent. Ownership of beneficial interests in this Warrant shall be shown on, and the transfer of such ownership shall be effected through, records maintained by the Warrant Agent (the “Warrant Register”). The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual written notice to the contrary.

(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 e-mail, facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”) to the Warrant Agent or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company or the Warrant Agent (or to the Company if the exercise

is made pursuant to a Cashless Exercise (as defined in Section 1(d)), of the Holder’s election to exercise this Warrant. Within one (1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Warrant Agent 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 (to the account set forth on Schedule A hereto) 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. The Holder and the Company or the Warrant Agent shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company or the Warrant Agent shall deliver any objection to any Notice of Exercise form within 2 Business Days of receipt of the applicable Notice of Exercise. On or before the first (1^st) Trading Day following the date on which the Company has received an Exercise Notice for a Cashless Exercise, the Company shall transmit by e-mail or facsimile an acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit B, to the Warrant Agent. On or before the third (3^rd) Trading Day following (A) in the event of a Cashless Exercise, the date on which the Company has received such Exercise Notice or (B) in the event of an exercise for cash, the later of (i) the date on which the Warrant Agent has received such Exercise Notice or (ii) the date on which the Warrant Agent receives the Aggregate Exercise Price (such date is referred to herein as the “Delivery Date”), the Company shall, (X) provided that (I) the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and (II) either a registration statement for the issuance to the Holder of the applicable Warrant Shares to be issued pursuant to such Exercise Notice is effective and the prospectus contained therein is usable or such Warrant Shares to be so issued are otherwise freely tradable, cause the Warrant Agent to 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 either of the immediately preceding clauses (I) or (II) are not satisfied, 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 (A) in the event of a Cashless Exercise, the date on which the Company has received such Exercise Notice or (B) in the event of an exercise for cash, the later of (i) the date on which the Warrant Agent has received such Exercise Notice or (ii) the date on which the Warrant Agent receives 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); provided, however, that if the date of such receipt is a date upon which the Common Stock transfer books of the Company are closed, such Holder shall be deemed to have become the record holder of such shares on, the next succeeding day on which the Common Stock transfer books of the Company are open. 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 (3) Business 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 up 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.

(b) Exercise Price. For purposes of this Warrant, “Exercise Price” means $[ ]², subject to adjustment as provided herein.

(c) Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, to issue to the Holder on or before the applicable Delivery Date, 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 (3^rd) 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 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 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) on or prior to the applicable Delivery Date, and if on or after such Delivery Date 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 (3) 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), the Holder may, in its sole discretion (and without limiting the Holder’s rights and remedies contained herein), exercise this Warrant in whole or in part and, from and after the 120 day anniversary of the Issuance Date, 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 receive upon such exercise a cash payment from the Company equal to the product of (i) the total number of shares with respect to which this Warrant is then being exercised multiplied by (ii) the Black Scholes Value (as defined below) (the “Exchange Amount”). In the Company’s sole discretion, if (x) no Equity Conditions has occurred or (y) an Equity Conditions Failure has occurred other than as a result of any of the conditions specified in clauses (ii) or (v) of the definition thereof, the Company may elect to treat such notice as a cashless exercise of the Warrant with respect to the number of shares specified in “A” below for the “Net Number” of shares of Common Stock determined according to the following formula with respect thereto (a “Cashless Exercise”), as follows:

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

C= the Closing Bid Price of the Common Stock as of two (2) Trading Days prior to the time of such exercise (as defined below).

(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. 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 Securities Exchange Act of 1934, as amended (the “1934 Act”), 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 amend or 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 one (1) Business Day 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 Certificate of Designation.

If at any time after the 120 day anniversary of the Issuance Date, for twenty (20) consecutive Trading Days the Closing Sale Price of the Common Stock for each Trading Day during such period is at a price greater than or equal to 25% above the Exercise Price as in effect at the end of such Trading Day (such period being the “Trigger Period”), then (provided no Equity Conditions Failure shall have occurred during such period or be continuing at any time during such period), the Company shall have the right to require the Holder to exercise for cash all, but not less than all, of this Warrant for all of the then-remaining Warrant Shares as further set forth below. The Company may exercise its right to require exercise under this Section 1(g) (the “Mandatory Exercise Right”) on one occasion (or, if a Mandatory Exercise Notice becomes null and void pursuant to this Section 1(g), such number of additional occasions as necessary to permit a Mandatory Exercise with respect to the entire amount of Warrant Shares

issuable hereunder). The Company shall exercise its Mandatory Exercise Right (to the extent permitted hereby) by delivering, within ten (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 below 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 1(g), which Trading Day shall be at least five (5) Trading Days but not more than fifteen (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 is then no Equity Conditions Failure existing 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; provided however, that so long as the Closing Sale Price of the Common Stock for each Trading Day between the Mandatory Exercise Notice Date and the Mandatory Exercise Date is at a price greater than or equal to 25% above the Exercise Price as in effect at the end of such Trading Day, the holder cannot exercise this warrant pursuant to Section 1(d) above. 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 Warrant Agent 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 1(g) to the contrary, if an Equity Conditions Failure occurs on any day between the occurrence of the Trigger Period and prior to 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 1(g), then it must simultaneously take the same action with respect to all of the other warrants issued to investors in the Offering, if any, held by any person other than Holder. By way of example, if the Exercise Price of the Warrant is $1.25 per share, and after the 120 day anniversary of the Issuance Date, the Closing Sale Price for twenty (20) consecutive Trading Days is greater than or equal to $1.5625 per share, the Company may exercise the Mandatory Exercise Right.

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 Purchased 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 Purchased 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 Purchased 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 Purchased 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 commercially reasonable efforts to solicit its shareholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the shareholders that they approve such proposal.

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 4, if the Company, at any time on or after the Issuance Date, (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.

(c) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein). In addition, and notwithstanding anything to the contrary contained herein, (x) upon a Cashless Exercise as set forth in Section 1(d) hereof, the number of Warrant Shares for which this Warrant is exercisable immediately following such Cashless Exercise shall be equal to (i) the number of Warrant Shares for which this Warrant was exercisable immediately prior to such Cashless

Exercise less (ii) the number of Warrant Shares as to which such Cashless Exercise was exercised (such number of Warrant Shares in this clause (ii) in respect of such Cashless Exercise being equal to “A” in such Cashless Exercise formula in respect of such Cashless Exercise) and (y) the number of Warrant Shares issuable hereunder shall automatically be increased, as necessary, to enable to the Company to comply with its obligations to issue the Net Number of shares of Common Stock under Section 1(d) hereof upon any Cashless Exercise hereunder.

(d) 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.

(e) Other Events. In the event that the Company shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 2(e) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, provided further that if the Required Holders (as defined below) do not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s board of directors and the Required Holders shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by the Company.

3. RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if the Company, at any time prior to the three year anniversary of the Issuance Date, shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to all or substantially all of the holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, indebtedness, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distributions would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any such shares of Common Stock as a result of such Distribution to such extent) and such Distribution to such

extent shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage), provided further, such Distribution shall be held in abeyance for the benefit of the Holder until such time as the Holder exercises this Warrant (whether in whole or in part), and subject to the foregoing proviso, upon each exercise of this Warrant the Company shall make such Distribution to the Holder with respect to each Warrant Share for which this Warrant is so exercised until such time as this Warrant has been exercised in full).

(a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if the Company, at any time prior to the three year anniversary of the Issuance Date, grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage), and provided further, that such Purchase Rights shall be held in abeyance for the benefit of the Holder until such time as the Holder exercises this Warrant (whether in whole or in part), and subject to the foregoing proviso, upon each exercise of this Warrant the Company shall deliver such Purchase Rights to the Holder with respect to each Warrant Share for which this Warrant is so exercised until such time as this Warrant has been exercised in full).

(b) Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 4(b) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements confirming the obligations of the Successor Entity as set forth in this paragraph (b) and (c) and elsewhere in this Warrant and an obligation to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into

account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Notwithstanding the foregoing, at the election of the Holder upon exercise of this Warrant following a Fundamental Transaction, the Successor Entity shall deliver to the Holder, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity), or other securities, cash, assets or other property, which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant).

(c) Black Scholes Value — FT. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder delivered at any time commencing on the date of the consummation of any such Fundamental Transaction through the date that is thirty (30) days after the consummation of any such Fundamental Transaction, the Company or the Successor Entity, at the election of the Holder, shall purchase this Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value — FT.

(d) Application. The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and shall be applied as if this Warrant (and any such subsequent warrants issued hereunder) were fully exercisable and without regard to any limitations on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum Percentage, applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of this Warrant (or any such other warrant)).

5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Charter (as defined in the Underwriting Agreement), Bylaws (as defined in the Underwriting 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 Purchased 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 Purchased Warrants, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Purchased Warrants then outstanding (without regard to any limitations on exercise).

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, 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. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders; provided however, that the Company shall not be obligated to provide such information if it is filed with the SEC through EDGAR and available to the public through the EDGAR system.

(a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant (or the Book Entry Warrant Certificate) to the Company or the Warrant Agent (or other designated agent), whereupon the Company or the Warrant Agent (or other designated agent) will forthwith issue and deliver upon the order of the Holder a new Warrant (or Book Entry Warrant Certificate) (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 (or Book Entry Warrant Certificate) (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 (or the Book Entry Warrant Certificate) (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 (including posting a bond) and, in the case of mutilation, upon surrender and cancellation of this Warrant (or the Book Entry Warrant Certificate), the Company shall execute and deliver to the Holder a new Warrant (or Book Entry Warrant Certificate) (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 (or of the Book Entry Warrant Certificate) by the Holder at the principal office of the Company, for a new Warrant or Warrants (or Book Entry Warrant Certificates) (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 (or Book Entry Warrant Certificate) 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 (or Book Entry Warrant Certificate) pursuant to the terms of this Warrant, such new Warrant (or Book Entry Warrant Certificate) (i) shall be of like tenor with this Warrant (or Book Entry Warrant Certificate), (ii) shall represent, as indicated on the face of such new Warrant (or Book Entry Warrant Certificate), the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant (or Book Entry Warrant Certificate) 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 (or Book Entry Warrant Certificates) 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 (or Book Entry Warrant Certificate) 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 in writing and shall be deemed given (w) the date of transmission, if such notice or communication is delivered via facsimile or email at the number or email address set forth below prior to 5:00 p.m. (New York time) on a Business Day, (x) on the date delivered, if delivered personally, (y) on the first Business Day following the deposit thereof with Federal Express or another recognized overnight courier, if sent by Federal Express or another recognized overnight courier, and (z) on the fourth Business Day following the mailing thereof with postage prepaid, if mailed by registered or certified mail (return receipt requested), in each case to the parties at the following addresses (or at such other address for a party as shall be specified by like notice).

(c) If to the Holder, to the address of such holder as shown on the Warrant Register. Any notice required to be delivered by the Company to the Holder may be given by the Warrant Agent on behalf of the Company.

The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) 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) and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities, indebtedness, or other property pro rata to holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information (to the extent it constitutes, or contains, material, non-public information regarding the Company or any of its Subsidiaries shall be made known to the public prior to or in conjunction with such notice being provided to the Holder and (iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction. 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 pursuant to a Current Report on Form 8-K.

9. AMENDMENT AND WAIVER. Except as otherwise expressly set forth herein, the provisions of this Warrant may be amended only with the written consent of the Company and the Required Holders. Any amendment effected in accordance with this Section 9 shall be binding upon the Holder and the Company, provided that no such amendment shall be effective to the extent that it (1) applies to less than all Purchased Warrants then outstanding, (2) imposes any obligation or liability on the Holder without the Holder’s prior written consent (which may be granted or withheld in the Holder’s sole discretion) or (3) applies retroactively. Except as otherwise expressly set forth herein, no waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party, provided that the Required Holders (in a writing signed by all of the Required Holders) may waive any provision of this Warrant, and any waiver of any provision of this Warrant made in conformity with the provisions of this Section 9 shall be binding on the Holder, provided that no such waiver shall be effective to the extent that it (1) applies to less than all Purchased Warrants then outstanding (unless a party gives a waiver as to itself only) or (2) imposes any obligation or liability on the Holder without the Holder’s prior written consent (which may be granted or withheld in the Holder’s sole discretion). Notwithstanding the foregoing, nothing contained in this Section 9 shall permit any amendment or waiver of any provision of Section 1(f) or the waiver of any Equity Conditions Failure if such failure in any manner resulted from clause (ii) of the definition thereof.

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.
