Section 2.    Exercise.

(a)    Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Issue Date and on or before the Termination Date by delivery to the Company (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) of a duly executed facsimile copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”) and, within the earlier of (i) 12:00 p.m. (Eastern Time) on the second Trading Day and (ii) 12:00 p.m. (Eastern Time) on the last Trading Day of the applicable Standard Settlement Period following the date said Notice of Exercise is delivered to the Company, payment of the aggregate Exercise Price of the shares thereby purchased pursuant to the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank (including an international branch office of a United States bank) or pursuant to the cashless exercise procedure specified in Section 2(c) below if specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within two (2) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of

Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

(b)    Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $6.72, subject to adjustment hereunder (the “Exercise Price”).

(c)    Cashless Exercise. This Warrant may also be exercised, in whole or in part, by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) * (X)] by (A), where:

If the foregoing calculation results in a negative number, then no Warrant Shares shall be issued upon a “cashless exercise” pursuant to this Section 2(c).

(d)    Mechanics of Exercise.

(i)    Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrant), and otherwise by electronic book entry credit or physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earliest of (1) two (2) Trading Days after the delivery to the Company of the Notice of Exercise, (2) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and (3) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”); provided, under no circumstances is the Company required to cause the Warrant Shares to be delivered prior to payment of the aggregate Exercise Price (other than in the case of a cashless exercise). Upon delivery of the Notice of Exercise, 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 (including with respect to Warrant Shares transmitted by crediting the account of the Holder’s or its designee’s balance account with the Depository Trust Company through its DWAC system), irrespective of the date of delivery of the Warrant Shares; provided that, payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise.

(ii)    Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(iii)    Rescission Rights. Subject to the Company’s receipt of the aggregate Exercise Price for the Warrant Shares subject to such Notice of Exercise, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise by delivering written notice to the Company at any time prior to the Company delivering such Warrant Shares.

(iv)    No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company

shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

(v)    Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto as Exhibit B (the “Assignment Form”) duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

(vi)    Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

Section 3.    Certain Adjustments.

(a)    Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides (including by way of stock split) outstanding shares of Common Stock into a larger number of shares or (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged, subject to the limitation on fractional shares in Section 2(d)(iv). Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b)    Reclassifications. If at any time after the Issue Date while this Warrant remains outstanding and unexpired in whole or in part, the Common Stock issuable upon exercise of this Warrant is changed into the same or a different number of shares of any class or classes of stock, this Warrant will thereafter represent the right to acquire such number and kind of securities as would have been issuable as a result of exercise of this Warrant and the Exercise Price therefor shall be appropriately adjusted.

(c)    Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number

of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

(d)    Notice to Holder.

(i)    Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

(ii)    Notice to Allow Exercise by Holder. If during the term in which this Warrant may be exercised by the Holder (A) the Company shall declare a dividend or any other distribution in whatever form (except a dividend or distribution subject to Section 3(a)) on the Common Stock, (B) the Company shall declare a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the Company proposes to effect a Fundamental Transaction, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least ten (10) calendar days prior to the applicable record or effective date hereinafter specified or the proposed date of closing in the case of a Fundamental Transaction stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined (the “Record Date”) or (y) the date on which such Fundamental Transaction is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such Fundamental Transaction. To the extent that any notice provided in this Warrant would constitute, or contain, material, non-public information regarding the Company or any of its Subsidiaries, then prior to delivering such notice, the Company shall promptly request the Holder’s agreement to receive material non-public information and to hold such information in confidence (without disclosing the nature of such information). If the Holder does not so agree, then the Company shall be excused from delivering the notice; provided that the Company shall promptly deliver such notice after such time, if any, that delivery would not provide the Holder with material non-public information regarding the Company or any of its Subsidiaries. The Holder shall not be entitled to any such dividend, distribution, redemption, rights or warrants if the Holder does not exercise this Warrant on or prior to the Record Date. This Warrant shall terminate in all respects and no longer be exercisable upon the closing of a Fundamental Transaction.

Section 4.    Transfer of Warrant.

(a)    Transferability. Subject to compliance with applicable securities laws, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant

at the principal office of the Company, together with an Assignment Form duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Prior to any such transfer, the transferee shall deliver a written statement to the Company that such transferee is an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act, and in the case of a transaction exempt from registration under the Securities Act, shall provide documentation reasonably satisfactory to the Company that such transaction does not require registration under the Securities Act. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, in the denomination or denominations specified in such instrument of assignment and bearing appropriate legends, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an Assignment Form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b)    New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Issue Date and shall be identical to this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

(c)    Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. 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.

(d)    Procedures Regarding Loss, Theft, Destruction or Mutilation of Warrant. If (a) this Warrant is mutilated and is surrendered to the Company for replacement or (b) both (i) there shall be delivered to the Company (A) a claim by Holder as to the destruction, loss or wrongful taking of this Warrant and a request thereby for a new replacement Warrant, and (B) such indemnity bond as may be required by the Company to save it and any agent of it as harmless and (ii) such other reasonable requirements as may be imposed by the Company as permitted by Section 8‑405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Company that such Warrant has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code, the Company shall execute and deliver to the registered Holder of the lost, wrongfully taken, destroyed or mutilated Warrant, in exchange therefore or in lieu thereof, a new Warrant of the same tenor and for a like aggregate number of Warrants. Upon the issuance of any new Warrant under this Section 4(d), the Company may require the payment of a sum sufficient

to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses (including the fees and expenses of counsel to the Company) in connection therewith.

(e)    Representations and Warranties by the Holder. The Holder represents and warrants to the Company as follows:

(i)    Purchase for Own Account. This Warrant and the Warrant Shares acquired upon exercise of this Warrant by the Holder will be acquired for investment for the Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Securities Act and the Holder has no present intention of selling or engaging in any public distribution of the same except pursuant to a registration or exemption. The Holder also represents that the Holder has not been formed for the specific purpose of acquiring this Warrant or the Warrant Shares.

(ii)    Disclosure of Information. The Holder has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and the Warrant Shares. The Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and the Warrant Shares and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to the Holder or to which the Holder has access.

(iii)    Investment Experience. The Holder understands that the acquisition of this Warrant and its underlying securities involves substantial risk. The Holder has experience as an investor in securities of companies similarly situated to the Company and acknowledges that the Holder can bear the economic risk of the Holder’s investment in this Warrant and the Warrant Shares and has such knowledge and experience in financial or business matters that the Holder is capable of evaluating the merits and risks of its investment in this Warrant and the Warrant Shares and/or has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables the Holder to be aware of the character, business acumen and financial circumstances of such persons.

(iv)    Accredited Investor Status; Principal Office. The Holder is an “accredited investor” within the meaning of Regulation D promulgated under the Securities Act. The Holder’s principal place of business is as set forth on the signature page hereto.

(v)    The Securities Act. The Holder understands that this Warrant and the Warrant Shares issuable upon exercise or conversion hereof have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Holder’s investment intent as expressed herein. The Holder understands that this Warrant and the Warrant Shares issued upon any exercise or conversion hereof must be held indefinitely unless subsequently registered under the Securities Act and qualified under applicable state securities laws, or unless exemption from such registration and qualification are otherwise available.

Section 5.    Miscellaneous.

(a)    No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3. Without limiting the rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 2(c) or cash in lieu of fractional shares pursuant to Section 2(d)(iv), in no event will the Company be required to pay cash in lieu of issuance of Warrant Shares upon exercise.

(b)    Reserved.

(c)    Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

(d)    Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares free from preemptive rights to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant and to take all steps necessary to increase the authorized number of shares of its Common Stock if at any time the authorized number of shares of Common Stock remaining unissued is insufficient to permit the exercise of this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, 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, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all

such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

(e)    Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflict of laws thereof.

(f)    Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not utilize cashless exercise, may have restrictions upon resale imposed by state and federal securities laws.

(g)    Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies.

(h)    Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Notice of Exercise) shall be in writing and shall be deemed given and as follows:
