Exhibit 4.1

WARRANT AGREEMENT

WARRANT AGREEMENT made as of November 13, 2014, between American Superconductor Corporation, a Delaware corporation (the “Company”), and American Stock Transfer & Trust Company, LLC, a New York limited liability trust company (“Warrant Agent”).

WHEREAS, the Company has sold units (“Units”), each consisting of one share of common stock (“Common Stock”) of the Company and 0.9 of a warrant, each whole warrant evidencing the right of the holder thereof to purchase one share of Common Stock for $1.10, subject to adjustment as described herein (the “Warrants”), pursuant to an Underwriting Agreement between the Company and ▇▇▇▇▇ and Company, LLC, as Representative of the Underwriters (the “Underwriting Agreement”), dated November 7, 2014; and

WHEREAS, the Units and the shares issuable upon exercise of the Warrants (“Warrant Shares”) were issued by the Company in a public offering pursuant to an effective shelf registration statement on Form S-3, Registration No. 333-198851 (“Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (“Act”); and

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange and exercise of the Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Warrant Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Warrant Agreement.

2. Warrant.

2.1. Form of Warrant. Each Warrant shall be issued in registered form only, shall be in substantially the form of Exhibit A hereto (the “Form of Warrant Certificate”), the

provisions of which are incorporated herein, and shall be signed by, or bear the facsimile signature of, the Chief Executive Officer or Chief Financial Officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.2. [Reserved.]

2.3. Registration.

2.3.1. Warrant Register. The Warrant Agent shall maintain books (“Warrant Register”), for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. The Warrants may be represented by definitive warrant certificates in physical form (“Definitive Warrant Certificates”) or by one or more book-entry warrant certificates (“Book-Entry Warrant Certificates”) deposited with the Depository Trust Company (the “Depository”) and registered in the name of Cede & Co., a nominee of the Depository. Definitive Warrant Certificates shall be in substantially the form annexed hereto as Exhibit A, the terms of which are incorporated into the Book-Entry Warrant Certificates and any Warrant statement relating thereto. Ownership of beneficial interests in the Book-Entry Warrant Certificates shall be shown on, and the transfer of such ownership shall be effected through, records maintained (i) by the Depository or its nominee for each Book-Entry Warrant Certificate; (ii) by institutions that have accounts with the Depository (each such institution, with respect to a Warrant in its account, a “Participant”); or (iii) directly on the book-entry records of the Warrant Agent with respect only to owners of beneficial interests that request such direct registration.

If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Company does not make alternative arrangements for book-entry settlement, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depository Definitive Warrant Certificates in physical form evidencing such Warrants.

2.3.2. Beneficial Owner; Registered Holder. The term “beneficial owner” shall mean any person in whose name ownership of a beneficial interest in a Warrant evidenced by (a) a Book-Entry Warrant Certificate is recorded in the records maintained

by (i) by the Depository or its nominee for each Book-Entry Warrant Certificate; (ii) by a Participant; or (iii) directly on the book-entry records of the Warrant Agent with respect only to owners of beneficial interests that request such direct registration or (b) a Definitive Warrant Certificate is recorded in the book-entry records of the Warrant Agent. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (“Registered Holder”), as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the warrant certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.3.3. Detachability of Warrants. The securities comprising the Units will be issued separately and will be separately transferable immediately upon issuance.

2.3.4. Uncertificated Warrants. Notwithstanding the foregoing and anything else herein to the contrary, the Warrants may be issued in uncertificated form if so specified by the Company.

3. Terms and Exercise of Warrants.

3.1. Exercise Price. Each Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price per whole share stated therein, subject to the adjustments provided in Sections 1, 2 and 3 of the Form of Warrant Certificate.

3.2. Duration of Warrants. A Warrant may be exercised only during the period commencing on the Exercisability Date and terminating at 5:00 P.M., New York time on the Expiration Date. Each Warrant not exercised on or before 5:00 P.M., New York time on the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Warrant Agreement shall cease immediately after 5:00 P.M., New York time on the Expiration Date.

3.3. Manner and Exercise and Issuance of Shares. Except as provided for in Section 3.4, Warrants may be exercised in the manner set forth in Section 1 of the Form of Warrant Certificate, in accordance with the terms and limitations set forth therein. Upon any such exercise, the Warrant Shares shall be issued in the manner set forth in Section 1 of the Form of Warrant Certificate, and subject to the restrictions set forth therein, which terms are hereby incorporated into the terms of the Book-Entry Warrant Certificates (and any Warrant statement relating thereto).

3.4. Exercise of Warrants with Warrant Agent. Notwithstanding Section 3.3, so long as the Warrant Agent maintains the Warrant Register, Warrants shall be exercised in the following manner:

3.4.1. Exercise and Payment. A Registered Holder may exercise a Warrant by delivering, not later than 5:00 P.M., New York time, on any Business Day after the Exercisability Date but not after 5:00 P.M., New York time on the Expiration Date (the “Exercise Date”) to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised free on the records of the Depository (the “Book-Entry Warrants”) to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository from time to time, (ii) an Exercise Notice, properly completed and executed by the Registered Holder substantially in the form attached as Exhibit A to the Form of Warrant Certificate or, in the case of a Book-Entry Warrant Certificate, properly delivered by the Participant in accordance with the Depository’s procedures, and (iii), except as provided in Section 3.4.6, the Aggregate Exercise Price for each Warrant to be exercised in lawful money of the United States of America by certified or official bank check or by bank wire transfer in immediately available funds. In the event of a “cashless exercise,” as provided in Section 3.4.6, the Definitive Warrant Certificate or Book-Entry Warrants, the Exercise Notice, and the Aggregate Exercise Price must be delivered to the Company at the address specified in Section 7.2.

If any of (A) the Definitive Warrant Certificate or the Book-Entry Warrants, (B) the Exercise Notice, or (C) the Exercise Price therefor, is received by the Warrant Agent after 5:00 P.M., Eastern time, on the specified Exercise Date, the Warrants will be deemed to be received and exercised on the Business Day next succeeding the Exercise Date. If the date specified as the Exercise Date is not a Business Day, the Warrants will be deemed to be received and exercised on the next succeeding day that is a Business Day. If the Warrants are received or deemed to be received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the Registered Holder or Participant, as the case may be, as soon as practicable. In no event will interest accrue on funds deposited with the Warrant Agent in respect of an exercise or attempted exercise of Warrants. The validity of any exercise of Warrants will be determined by the Company in its sole discretion and such determination will be final and binding upon the Registered Holder and the Warrant Agent. Neither the Company nor the Warrant Agent shall have any obligation to inform a Registered Holder of the invalidity of any exercise of Warrants.

The Warrant Agent shall deposit all funds received by it in payment of the Warrant Price in the account of the Company maintained with the Warrant Agent for such purpose and shall advise the Company at the end of each day on which funds for the exercise of the Warrants are received of the amount so deposited to its account. The Warrant Agent shall promptly confirm such advice to the Company in writing.

3.4.2. Issuance of Certificates. The Warrant Agent shall, within a reasonable time, advise the Company and the transfer agent and registrar in respect of (a) the Warrant Shares issuable upon such exercise as to the number of Warrants exercised in accordance with the terms and conditions of this Agreement, (b) the instructions of each Registered Holder or Participant, as the case may be, with respect to delivery of the

Warrant Shares issuable upon such exercise, and the delivery of Definitive Warrant Certificates, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise (in accordance with Section 1(a) of the Form of Warrant Certificate), (c) in case of a Book-Entry Warrant Certificate, the notation that shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, a Participant, or the Warrant Agent, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise and (d) such other information as the Company or such transfer agent and registrar shall reasonably require.

The Company shall, by 5:00 P.M., Eastern time, on the third Business Day next succeeding the Exercise Date of any Warrant and the clearance of the funds, if any, in payment of the Warrant Price (the “Warrant Shares Delivery Date”), execute, issue and deliver to the Warrant Agent, the Warrant Shares to which such Registered Holder or Participant, as the case may be, is entitled, in fully registered form, registered in such name or names as may be directed by such Registered Holder or the Participant, as the case may be. Upon receipt of such Warrant Shares, the Warrant Agent shall, by 5:00 P.M., Eastern time, on the third Business Day next succeeding such Exercise Date, transmit such Warrant Shares to or upon the order of the Registered Holder or Participant, as the case may be.

In lieu of delivering physical certificates representing the Warrant Shares issuable upon exercise, provided the Company’s transfer agent is participating in the Depository’s Fast Automated Securities Transfer program, the Company shall use its reasonable best efforts to cause its transfer agent to electronically transmit the Warrant Shares issuable upon exercise to the Registered Holder or the Participant by crediting the account of the Registered Holder’s prime broker with the Depository or of the Participant through its Deposit Withdrawal Agent Commission system. The time periods for delivery described in the immediately preceding paragraph shall apply to the electronic transmittals described herein.

If the Warrant Agent fails to comply with the preceding paragraphs in this Section 3.4.2 by the Warrant Shares Delivery Date, then the Registered Holder will have the right to rescind its exercise.

If the Company shall fail for any reason or for no reason to execute, issue and deliver to the Warrant Agent the Warrant Shares by the Warrant Shares Delivery Date, then the Company shall, before the Warrant Shares Delivery Date, in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Buy-In Price, at which point the Company’s obligation to deliver such Warrant Shares shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares 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, times (B) the Closing Bid Price on the date of exercise.

3.4.3. No Fractional Exercise. No fractional shares of Common Stock will be issued upon the exercise of the Warrant, but rather the Company will make a cash

payment to the Holder in lieu thereof based on the Closing Sale Price on the Exercise Date; provided, however, that, in lieu of such cash payment, the number of shares of Common Stock to be issued may, at the Company’s option, be rounded up to the nearest whole number. If fewer than all of the Warrants evidenced by a Definitive Warrant Certificate are exercised, a new Definitive Warrant Certificate for the number of unexercised Warrants remaining shall be executed by the Company and delivered to the holder of this Warrant Certificate at the address specified on the books of the Warrant Agent or as otherwise specified by such Registered Holder. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, a Participant, of the Warrant Agent, as appropriate, evidencing the balance of the Warrants remaining after such exercise.

3.4.4. Taxes. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of the Warrant (except as set forth in Section 15 of the Form of Warrant Certificate).

3.4.5. Date of Issuance. At the Close of Business on the date of delivery of a valid Exercise Notice, 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.

3.4.6. Cashless Exercise. If an effective registration statement is available for the issuance of the Warrant Shares, the Warrants may only be exercised through a Cash Exercise. Notwithstanding anything contained herein to the contrary, in the event an effective registration statement is not then available for the issuance of the Warrant Shares, 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 receive upon such exercise the “Net Number” of shares of Common Stock determined in the manner set forth in Section 1(e) of the Form of Warrant Certificate and subject to Section 1(f) to the Form of Warrant Certificate.

3.4.7. Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed.

3.4.8. Beneficial Ownership Limitation. The Warrant Agent shall not effect the exercise of a Warrant, and the Holder shall not have the right to exercise a Warrant, to the extent that after giving effect to such exercise, the Holder (together with the Holder’s affiliates) would beneficially own in excess of the Maximum Percentage, as set forth in Section 1(h) of the Form of Warrant Certificate.

4. Adjustments.

4.1. Adjustment of Exercise Price and Number of Warrant Shares; Fundamental Transactions. The Exercise Price and the number of Warrant Shares issuable upon exercise shall be subject to adjustment from time to time as provided in Sections 2 and 3 of the Form of Warrant Certificate.

4.2. Notices.

4.2.1. Notices of Changes. Whenever an adjustment is proposed or effected that requires notice by the Company, as provided in Section 8 of the Form of Warrant Certificate, the Company shall deliver to the Warrant Agent the notices or statements required by Section 8 of the Form of Warrant Certificate, and shall cause a copy of such notices or statements to be sent or communicated to each Holder pursuant to Section 8 of the Form of Warrant Certificate.

4.2.2. Form of Warrant Certificate. The Form of Warrant Certificate need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Exercise Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may at any time in its sole discretion make any change in the Form of Warrant Certificate that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

5. Transfer and Exchange of Warrants.

5.1. Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2. Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or in any Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate may be transferred only in whole and only to the Depository, to another nominee of the Depository, to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange therefor until the Warrant Agent has received an

opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. Upon any such registration of transfer, the Company shall execute, and the Warrant Agent shall countersign and deliver, in the name of the designated transferee a new Definitive Warrant Certificate or Book-Entry Warrant Certificate (or Definitive Warrant Certificates or Book-Entry Warrant Certificates) of any authorized denomination evidencing in the aggregate a like number of unexercised Warrants.

5.3. Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a Definitive Warrant Certificate or Book-Entry Warrant Certificate for a fraction of a Warrant.

5.4. Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.5. Warrant Execution. The Warrant Agent is hereby authorized to deliver, in accordance with the terms of this Warrant Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

6. Concerning the Warrant Agent and Other Matters.

6.1. Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

6.2. Resignation, Consolidation, or Merger of Warrant Agent.

6.2.1. Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of the Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any

successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

6.2.2. Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such appointment.

6.2.3. Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion, or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to the business of the Warrant Agent, shall be the successor Warrant Agent under this Warrant Agreement without any further act.

6.3. Fees and Expenses of Warrant Agent.

6.3.1. Remuneration. The Company agrees to pay the Warrant Agent the remuneration set forth in that certain Fee Proposal delivered to the Company on November 4, 2014 for its services as such Warrant Agent hereunder and will reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

6.3.2. Further Assurances. The Company agrees to 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 of the provisions of this Warrant Agreement.

6.4. Liability of Warrant Agent.

6.4.1. Reliance on Company Statement. Whenever in the performance of its duties under this Warrant 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 a statement signed by the President or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Warrant Agreement.

6.4.2. Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Warrant Agreement except as a result of the Warrant Agent’s gross negligence, willful misconduct, or bad faith.

6.4.3. Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Warrant Agreement or with respect to the validity or execution of any Warrant; nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Warrant Agreement or in any Warrant; nor shall it be responsible to make calculations under Section 3 or any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; 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 Warrant Agreement or any Warrant or as to whether any shares of Common Stock will when issued be valid and fully paid and nonassessable.

6.5. Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Warrant Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all moneys received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of Warrants.

6.6. Limitation on Liability of Warrant Agent. In no event shall the Warrant Agent have any liability for any incidental, special, statutory, indirect or consequential damages, or for any loss of profits, revenue, data or cost of cover.

7. Miscellaneous Provisions.

7.1. Successors. All the covenants and provisions of this Warrant 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.

Within two (2) days following the Exercise Notice, the Holder shall make payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash or by wire transfer of immediately available funds, or provided the conditions for Cashless Exercise (as defined below) set forth in Section 1.1.(e) are satisfied, by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise. The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with

respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the first (1^st) Business Day following the date on which the Company has received a valid Exercise Notice, the Company shall transmit by facsimile or e-mail transmission an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third (3^rd) Business Day following the date on which the Company has received a valid Exercise Notice and provided that the Company has received payment of the Aggregate Exercise Price as provided above, the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of Warrant Shares 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 dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. At the Close of Business on the date of delivery of a valid Exercise Notice and provided that the Company has received payment of the Aggregate Exercise Price as provided above, 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 1.1.(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 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 a new Warrant (in accordance with Section 6.1.(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 will be issued upon the exercise of this Warrant, but rather the Company will make a cash payment to the Holder in lieu thereof based on the Closing Sale Price on the Exercise Date; provided, however, that, in lieu of such cash payment, the number of shares of Common Stock to be issued may, at the Company’s option, be rounded up to the nearest whole number. Except as set forth in Section 15, the Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. No Exercise Notice shall be considered valid unless complete and validly executed by the Holder unless deemed so by the Company. All determinations of the validity of an Exercise Notice shall be made by the Company in good faith.

(b) Exercise of Warrants with Warrant Agent. Notwithstanding Section 1.1.(a), so long as the Warrant Agent maintains the Warrant Register, Warrants shall be exercised in the manner set forth in Section 3.4 of the Warrant Agreement.

(c) Exercise Price. For purposes of this Warrant, “Exercise Price” means $1.10, subject to adjustment as provided herein.

(d) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within three (3) Business Days of receipt of the Exercise Notice in compliance with the terms of this Section 1, 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 in each case as provided above, and if on or after such Trading Day 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 shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company, then 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, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares 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, times (B) the Closing Bid Price on the date of exercise.

(e) Cashless Exercise. If an effective registration statement is available for the issuance of the Warrant Shares, the Warrants may only be exercised through a cash exercise (a “Cash Exercise”). Notwithstanding anything contained herein to the contrary, in the event an effective registration statement is not then available for the issuance of the Warrant Shares, 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 receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):


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

For purposes of the foregoing formula:

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

the arithmetic average of the Closing Sale Prices of the shares of Common Stock for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the Exercise Notice;

the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise; and

the Closing Sale Price on the date of the Exercise Notice.

(f) Rule 144. For purposes of Rule 144(d) promulgated under the Securities Act, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the Issuance Date.

(g) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed.

(h) Beneficial Ownership Limitation. The Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, the Holder (together with the Holder’s affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by the Holder and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding, in each case as of the date such report, announcement or notice speaks. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of the Warrants. For the avoidance of doubt, to the extent the limitation set forth in this Section 1.1.(h) applies, the determination (i) of whether the exercise of this Warrant may be effected (vis-a-vis other options or convertible securities owned by the Holder or any of its Affiliates) and (ii) of which such options or convertible securities shall be convertible, exercisable or exchangeable (as the case may be, 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). The provisions of this paragraph shall be construed and implemented in a manner other than in strict conformity with the terms of this Section 1.1.(h) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows:

(a) Stock Dividends and Splits. If the Company, at any time on or after the Offer 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 stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately at the Close of Business on the effective date of such subdivision or combination.

(b) Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security (other than the Common Stock which shall be subject to Section 2(a)) (a “Distribution”), then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including the Trading Day immediately preceding the record date mentioned above (the “Average Price”), and of which the numerator shall be such Average Price on such record date less the then per share fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock as determined by the Company in good faith. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately at the Close of Business on the record date mentioned above. Notwithstanding the foregoing, if any adjustment pursuant to this Section 2(b) would cause the Exercise Price of this Warrant to be less than the par value of a share of Common Stock, in lieu of the foregoing adjustment, the Holder shall be entitled to participate in such Distribution (and any subsequent

Distributions) 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 or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date of 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, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder and the exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).

(c) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section 2(a) or Section 2(b), 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).

(d) Adjustment Upon Issuance of Shares of Common Stock. If and whenever on or after the Issuance Date, the Company issues or sells, or in accordance with this Section 2(d) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold for consideration per share (the “New Issuance Price”) less than the Exercise Price in effect immediately prior to such issue or sale or deemed issuance or sale (such Exercise Price then in effect is referred to as the “Applicable Price”, and the foregoing a “Dilutive Issuance”) (such number being appropriately adjusted to reflect the occurrence of any event described in Section 2(a) or Section 2(b)), then, immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the product of (A) the Applicable Price and (B) the quotient determined by dividing (1) the sum of (I) the product derived by multiplying the Applicable Price and the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any, received by the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Applicable Price by (II) the number of shares of Common Stock Deemed Outstanding immediately after such Dilutive Issuance. For all purposes of the foregoing (including, without limitation, determining the adjusted Exercise Price, the consideration per share and the New Issuance Price under this Section 2(d), the following shall be applicable:

(i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(d)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(d)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other

consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(d), except as contemplated below, no further adjustment of the Exercise Price shall be made by reason of such issue or sale.

(iii) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options referred to in Section 2(d)(i), the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities referred to in Section 2(d)(i) or 2(d)(ii), or the rate at which any Convertible Securities referred to in Section 2(d)(i) or 2(d)(ii) are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(d)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. On the expiration of any Options referred to in Section 2(d)(i) or any Convertible Securities referred to in Section 2(d)(ii), or the termination of any such right to exercise, convert or exchange such Options or Convertible Securities, the Applicable Price then in effect hereunder shall forthwith be increased to the Applicable Price which would have been in effect at the time of such expiration or termination had such Options or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued.

(iv) Calculation of Consideration Received. If any Option or Convertible Security or Adjustment Right is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company, together comprising one integrated transaction, (x) such Option or Convertible Security (as applicable) or Adjustment Right (as applicable) will be deemed to have been issued for consideration equal to the Black Scholes Consideration Value thereof and (y) the other securities issued or sold or deemed to have been issued or sold in such integrated transaction shall be deemed to have been issued for consideration equal to the difference of (I) the aggregate consideration received or receivable by the Company minus (II) the Black

Scholes Consideration Value of each such Option or Convertible Security (as applicable) or Adjustment Right (as applicable). If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount of consideration received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company for such securities will be the arithmetic average of the VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

(v) Notice of At-The-Market Draws. Solely with respect to issuances or deemed issuances of shares of Common Stock of the Company under any “at-the-market” or similar arrangement pursuant to which the Company issues Common Stock (an “ATM Facility”), but specifically excluding any “equity line of credit” or other similar arrangement, the Company shall notify the Holder of any reductions in the Exercise Price required by Section 2(d) as a result of issuances or deemed issuances under an ATM facility as follows: (x) with respect to any reduction in the Exercise Price, in the aggregate, of at least $0.05, within one (1) Business Day of such reduction in the Exercise Price or (y) otherwise, with respect to any reduction in the Exercise Price in any calendar month, on the first Business Day of the immediately subsequent calendar month. For the avoidance of doubt, (i) no reduction in the Exercise Price required by Section 2(d) as a result of issuances or deemed issuances under an ATM facility shall occur during the course of a calendar month until the amount of such reduction in Exercise Price otherwise required by Section 2(d) as a result of such issuances or deemed issuances during such calendar month shall be at least $0.05 and (ii) except as set forth in the preceding clause (i), reductions in Exercise Price required by Section 2(d) as a result of issuances or deemed issuances under an ATM facility shall only be determined at the end of each calendar month and only

with respect to the issuances or deemed issuances under such ATM facility since the later of (x) the end of the preceding calendar month or (ii) the last adjustment made pursuant to the preceding clause (i). For purposes hereof, any issuance or sale, or deemed issuance or sale, of shares of Common Stock in a calendar month under an ATM Facility shall not be aggregated with any such issuance or sale on any other calendar month.

(vi) Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be).

(e) Calculations. All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100^th of a share, as applicable.

3. FUNDAMENTAL TRANSACTIONS.

(a) Fundamental Transactions. If a Fundamental Transaction occurs as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such Fundamental Transaction, a “Share Exchange Event”; any such stock, other securities or other property or assets, “Reference Property”; and the amount of Reference Property that a holder of one share of Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange Event, a “Reference Property Unit”), then from and after the effective time of such Share Exchange Event, upon exercise of this Warrant, for each share of Common Stock that the Company would otherwise be obligated to deliver with respect to such exercise, the Company will instead deliver a Reference Property Unit. If such Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property shall be deemed to be (a) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (b) if no holders of the Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of the Common Stock, and (ii) a Reference Property Unit shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall not enter into or be party to such a Share Exchange Event 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 3.1.(a), including agreements 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 Reference Property Units equivalent to the number

of 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 Share Exchange Event, and with an exercise price which applies the Exercise Price hereunder to such Reference Property Units. Upon the consummation of each such Share Exchange Event, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Share Exchange Event, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 3.1.(a) to permit the Share Exchange Event without the assumption of this Warrant by the Successor Entity. In addition, in the event of a Fundamental Transaction, at the request of the Holder delivered at any time commencing on the earliest to occur of (x) the public disclosure of any Fundamental Transaction, (y) the consummation of any Fundamental Transaction and (z) the Holder first becoming aware of any Fundamental Transaction through the thirtieth (30^th) day after the later of (x) the date of such Fundamental Transaction and (y) the date of the public disclosure of the consummation of such Fundamental Transaction by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Business Days after such request, cash in an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant outstanding on the date of the consummation of such Fundamental Transaction.

(b) Application. The provisions of this Section 3 shall apply similarly and equally to successive Fundamental Transactions and shall be applied as if this Warrant (and any such subsequent warrants) 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)).

4. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws, 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 provided for herein. 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 nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as this Warrant is 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 this Warrant, 100% of the number of shares of Common Stock issuable upon exercise of this Warrant then outstanding (without regard to any limitations on exercise).

5. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. The Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a 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 such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any obligations on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such obligations are asserted by the Company or by creditors of the Company.

6. REISSUANCE OF WARRANTS.

(a) Transfer of Warrant. Subject to Section 6(e), if this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company or its designated agent and deliver the completed and executed Assignment Form, in the form attached hereto as Exhibit B, whereupon the Company or such agent will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 6.1.(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 6.1.(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, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary 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 6.1.(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

The foregoing notwithstanding, the Company may extend the Expiration Date and reduce the Exercise Price without the consent of the Holder.

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.

Such investment bank’s or accountant’s determination or calculation (as the case may be) shall be binding upon all parties absent demonstrable error.

The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, 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 damages for any failure by the Company to comply with the terms of this Warrant.

The Company shall provide all information and documentation to the Holder that is requested in writing by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Warrant.

16. Participation Right in Variable Rate Transactions. At any time during the period commencing on the Offer Date and ending on the first anniversary of the Offer Date (the “Participation Right Period”), neither the Company nor any of its Subsidiaries shall, directly or indirectly, effect any Variable Rate Transaction during the Participation Right Period (each, a “Subsequent Placement”, unless the Company shall have first complied with this Section 16. The Company and the Holder acknowledge and agree that the right set forth in this Section 16 is a right granted by the Company, separately and exclusively, to the sole initial purchaser of Registered Warrants from the underwriter (or its agents and co-underwriters) pursuant to the Underwriting Agreement (each a “Registered Holder”) and that such right is not transferable to any subsequent Holder.

(i) At least five (5) Trading Days prior to any proposed or intended Subsequent Placement, the Company shall deliver to each Registered Holder a written notice (each such notice, a “Pre-Notice”), which Pre-Notice shall not contain any information (including, without limitation, material, non-public information) other than: (i) if the proposed Offer Notice (as defined below) constitutes or contains material, non-public

information, a statement asking whether the Investor is willing to accept material non-public information or (ii) if the proposed Offer Notice does not constitute or contain material, non-public information, (A) a statement that the Company proposes or intends to effect a Subsequent Placement, (B) a statement that the statement in clause (A) above does not constitute material, non-public information and (C) a statement informing such Registered Holder that it is entitled to receive an Offer Notice (as defined below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Registered Holder within three (3) Trading Days after the Company’s delivery to such Registered Holder of such Pre-Notice, and only upon a written request by such Registered Holder, the Company shall promptly, but no later than one (1) Trading Day after such request, deliver to such Registered Holder an irrevocable written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the Persons (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to or exchange with such Registered Holder in accordance with the terms of the Offer such Registered Holder’s pro rata portion of the Offered Securities, provided that the number of Offered Securities which such Registered Holder shall have the right to subscribe for under this Section 16 shall be (a) based on such Registered Holder’s pro rata portion of such Registered Warrants initially acquired from the Underwriter (or its agents or co-underwriters) (the “Basic Amount”), and (b) with respect to each Registered Holder that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Registered Holders as such Registered Holder shall indicate it will purchase or acquire should the other Registered Holders subscribe for less than their Basic Amounts (the “Undersubscription Amount”).

(ii) To accept an Offer, in whole or in part, such Registered Holder must deliver a written notice to the Company prior to the end of the third (3^rd) Business Day after such Registered Holder’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of such Registered Holder’s Basic Amount that such Registered Holder elects to purchase and, if such Registered Holder shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Registered Holder elects to purchase (in either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Registered Holders are less than the total of all of the Basic Amounts, then such Registered Holder who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), such Registered Holder who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of such Registered Holder bears to the total Basic Amounts of all Registered Holders that have subscribed for Undersubscription

Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to each Registered Holder a new Offer Notice and the Offer Period shall expire on the third (3^rd) Business Day after such Registered Holder’s receipt of such new Offer Notice.

(iii) The Company shall have five (5) Business Days from the expiration of the Offer Period above (i) to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by a Registered Holder (the “Refused Securities”) pursuant to a definitive agreement(s) (the “Subsequent Placement Agreement”), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto.

(iv) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 16(iii) above), then such Registered Holder may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that such Registered Holder elected to purchase pursuant to Section 16(ii) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Registered Holders pursuant to this Section 16 prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Registered Holder so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Registered Holders in accordance with Section 16(i) above.

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Registered Holder shall acquire from the Company, and the Company shall issue to such Registered Holder, the number or amount of Offered Securities specified in its Notice of Acceptance. The purchase by such Registered Holder of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and such Registered Holder of a separate purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Registered Holder and its counsel.

(vi) Any Offered Securities not acquired by a Registered Holder or other Persons in accordance with this Section 16 may not be issued, sold or exchanged until they are again offered to such Registered Holder under the procedures specified in this Agreement.

(vii) The Company and each Registered Holder agree that if any Registered Holder elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or provision whereby such Registered Holder shall be required to agree to any restrictions on trading as to any securities of the Company or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement previously entered into with the Company or any instrument received from the Company.

(viii) Notwithstanding anything to the contrary in this Section 16 and unless otherwise agreed to by such Registered Holder, the Company shall either confirm in writing to such Registered Holder that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case, in such a manner such that such Registered Holder will not be in possession of any material, non-public information, by the fifth (5^th) Business Day following delivery of the Offer Notice. If by such fifth (5^th) Business Day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction has been received by such Registered Holder, such transaction shall be deemed to have been abandoned and such Registered Holder shall not be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries. Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide such Registered Holder with another Offer Notice and such Registered Holder will again have the right of participation set forth in this Section 16. The Company shall not be permitted to deliver more than one such Offer Notice to such Registered Holder in any sixty (60) day period, except as expressly contemplated by the last sentence of Section 16(ii).

(ix) The restrictions contained in this Section 16 shall not apply in connection with the issuance of any Excluded Securities or any issuances (or deemed issuances) pursuant to an ATM Facility.
