The Exercise Price and the number of Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3.2.

(b) Adjustments for Other Dividends and Distributions.

3.3 Adjustments for Reclassifications. If the Common Stock issuable upon the conversion of this Warrant shall be changed into the same or a different number of shares of any class(es) or series of stock and/or the right to receive property, whether by reclassification or otherwise (other than an adjustment under Sections 3.1 and 3.2 or a merger, consolidation, or sale of assets provided for under Section 3.4), then and in each such event, the Holder hereof shall have the right thereafter to convert each Warrant Share into the kind and amount of shares of stock and other securities and property receivable upon such reclassification, or other change by holders of the number of shares of Common Stock into which such Warrant Shares would have been convertible immediately prior to such reclassification or change, all subject to successive adjustments thereafter from time to time pursuant to and in accordance with, the provisions of this Section 3.

such dissolution, as the case may be, shall receive, in lieu of the Warrant Shares issuable on such exercise immediately prior to such consummation or such effective date, as the case may be, the stock and property (including cash) to which the Holder would have been entitled upon the consummation of such consolidation or merger, or sale or transfer, or in connection with such dissolution, as the case may be, if the Holder had so exercised this Warrant immediately prior thereto (assuming the payment by the Holder of the Exercise Price therefor as required hereby in a form permitted hereby, which payment shall be included in the assets of the Company for the purposes of determining the amount available for distribution), all subject to successive adjustments thereafter from time to time pursuant to, and in accordance with, the provisions of this Section 3. The Company shall not effect any such reorganization, consolidation, merger, sale or transfer unless, prior to the consummation thereof, the successor entity (if other than the Company) resulting from the consolidation or merger or the entity purchasing such assets assumes by written instrument the obligation to deliver to each holder of Warrants such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to acquire; provided, that any assumption shall not relieve the Company of its obligations hereunder.

3.5 Continuation of Terms. Upon any reorganization, consolidation, merger or transfer (and any dissolution following any such transfer) referred to in this Section 3, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of Common Stock and other securities and property receivable upon the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any such Common Stock or other securities, including, in the case of any such transfer, the Person acquiring all or substantially all of the properties or assets or more than 50% of the voting capital stock of the Company (whether issued and outstanding, newly issued or from treasury or any combination thereof), whether or not such Person shall have expressly assumed the terms of this Warrant.

3.6 Minimum Adjustment of Exercise Price. If the amount of any adjustment of the Exercise Price required pursuant to this Section 3 would be less than one-tenth (1/10) of one percent (1%) of the Exercise Price in effect at the time such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate at least one tenth (1/10) of one percent (1%) of such Exercise Price.

3.7 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price and number of Warrant Shares pursuant to this Section 3, this Warrant shall, without any action on the part of the Holder, be adjusted in accordance with this Section 3, and the Company, at its expense, promptly shall compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to the Holder a certificate setting forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company will forthwith send a copy of each such certificate to the Holder in accordance with Section 9.4 below.

7.3 No Restrictions on Transfer. Subject to compliance with applicable federal and state securities laws and Sections 6.1 and 6.2 of the Securities Purchase Agreement, this Warrant and any portion hereof, the Warrant Shares and the rights hereunder may be transferred by the Holder in its sole discretion at any time and to any Person or Persons, including without limitation Affiliates and affiliated groups of such Holder, without the consent of the Company.

this Warrant (after giving effect to any and all adjustments to the number and kind of Warrant Shares purchasable upon exercise of this Warrant).

9.2 No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities, sale or other transfer of any of its assets or properties, 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 action as may be necessary or appropriate in order to protect the rights of the Holder hereunder against impairment. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the amount payable therefor on such exercise, and (b) will take all action that 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.

Except as provided herein (including Sections 3 and 5), the Holder shall not be entitled to vote or to receive dividends or to be deemed the holder of Common Stock that may at any time be issuable upon exercise of this Warrant for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or to receive notice of meetings (except to the extent otherwise provided in this Warrant), or to receive dividends or subscription rights, until the Holder shall have exercised this Warrant and been issued Warrant Shares in accordance with the provisions hereof and continues to hold Warrant Shares.

(b) All correspondence to the Holder shall be addressed to the Holder at its address appearing in the books maintained by the Company.

10. Amendment and Waiver. No failure or delay of the Holder in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Holder are cumulative and not exclusive of any rights or remedies which it would otherwise have. This Warrant is one of a series of Warrants issued by the Company, all dated the date hereof and of like tenor, except as to the number of shares of Common Stock subject thereto (collectively, the “Company Warrants”). Any term of this Warrant may be amended or waived upon the written consent of the Company and the holders of Company Warrants representing at least a majority of the number of shares of Common Stock then subject to outstanding Company Warrants; provided that (i) any such amendment or waiver must apply to all Company Warrants then outstanding; (ii) the number of Warrant Shares subject to this Warrant, the Exercise Price or Expiration Date of this Warrant and the number of shares or class of stock obtainable upon exercise of this Warrant may not be amended, (iii) the right to exercise this Warrant may not be waived, without the written consent of the Holder of this Warrant (it being agreed that an amendment to or waiver under any of the provisions of Section 3 of this Warrant shall not be considered an amendment of the number of Warrant Shares or the Exercise Price) and (iv) any amendment that adversely affects any particular Holder without a corresponding affect upon all Holders must be approved by the particular Holder so affected. The Company shall promptly give notice to all holders of the Company Warrants of any amendments effected in accordance with this Section 10.

11. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York, as such laws are applied to contracts entered into and wholly to be performed within the State of New York and without giving effect to any principles of conflicts or choice of law that would result in the application of the laws of any other jurisdiction.

12. Covenants To Bind Successor and Assigns. All covenants, stipulations, promises and agreements in this Warrant contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not.

13. Severability. In case any one or more of the provisions contained in this Warrant shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

14. Construction. The definitions of this Warrant shall apply equally to both the singular and the plural forms of the terms defined. Wherever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The section and paragraph headings used herein are for convenience of reference only, are not part of this Warrant and are not to affect the construction of or be taken into consideration in interpreting this Warrant.

15. Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any

action for specific performance that a remedy at law would be adequate. In any action or proceeding brought to enforce any provision of this Warrant or where any provision hereof is validly asserted as a defense, the successful party to such action or proceeding shall be entitled to recover reasonable attorneys’ fees in addition to any other available remedy.
