Each Warrant evidenced hereby may be exercised by the Holder at any time on the Exercise Date, upon the terms and subject to the conditions set forth herein, by delivery to the Corporation of a completed Notice of Exercise in the form attached as Schedule A hereto, along with payment of the Purchase Price. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the Exercise Date and the person entitled to receive shares of restricted common stock of the Corporation deliverable upon such exercise shall be treated for all purposes as the Holder of a Warrant Share upon the exercise of the applicable Warrant as of the close of business on the Exercise Date. Promptly following, and in any event within ten (10) business days after, the date on which the Corporation first receives clearance of all funds received in payment of the Purchase Price pursuant to this Warrant Certificate, the Corporation shall cause to be issued and delivered to the person or persons entitled to receive the same, a certificate or certificates evidencing the issuance to such Holder of the applicable number of Warrant Shares (plus a Warrant Certificate for any remaining issued but unexercised Warrants of the Holder). Notwithstanding the foregoing sentence, in the event that any registration or qualification (or filing for exemption from any such requirements) is required prior to the issuance of such Warrant Shares by the Corporation in accordance with Section 3(b) below, then the obligation to deliver any such certificates shall arise only upon completion of such requirements and at such time as the Corporation may lawfully do so.

Upon the exercise of the Warrants represented hereby, if the Corporation so requests, the Holder shall certify to the Corporation that it is not exercising such Warrants with a view to distribute the Warrant Shares in violation of the Securities Act, and shall provide such other investor representations as the Corporation may require to confirm the ability of the Corporation to rely upon the exemption from registration under the Securities Act which applies to the distribution of Warrant Shares at the time of such distribution.

The Corporation covenants that it will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issue upon the valid exercise of Warrants, such number of Warrant Shares as shall then be issuable upon the exercise of all Warrants then outstanding. The Corporation covenants that all Warrant Shares which shall be issuable upon exercise of the Warrants shall, at the time of delivery, be duly and validly issued, fully-paid, non-assessable and free from all taxes, liens and charges with respect to the issuance thereof (other than those which the Corporation shall promptly pay or discharge, or any liens created thereon by the Holder thereof and/or any predecessor of such Holder).

The Corporation shall not be obligated to deliver any Warrant Shares pursuant to the exercise of the Warrants represented hereby unless and until a registration statement

under the Securities Act and/or under any applicable state securities laws and regulations, with respect to such securities is effective, or an exemption from such registration is available to the Corporation at the time of such exercise. The Warrants represented hereby may not be exercised by, nor Warrant Shares issued to, the Holder hereof in any jurisdiction in which such exercise and issuance would be unlawful.

The Corporation shall pay all documentary, stamp or similar taxes and other governmental charges that may be imposed with respect to the issuance of the Warrants, or the issuance or delivery of any Warrant Shares upon exercise of the Warrants.

Stock Splits, etc. The number and kind of securities purchasable upon the exercise of this Warrant and the Purchase Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Corporation shall (i) pay a dividend in shares of Common Stock, or securities convertible or exchangeable into Common Stock, or make a distribution in shares of Common Stock, or securities convertible or exchangeable into Common Stock, to all holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Warrant Shares or other securities of the Corporation which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Warrant Shares or other securities of the Corporation which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such adjustment at a Purchase Price per Warrant Share or other security obtained by multiplying the Purchase Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately

prior to such adjustment and dividing by the number of Warrant Shares or other securities of the Corporation resulting from such adjustment. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. In case the Corporation shall reorganize its capital, reclassify its capital stock, consolidate or merge with or into another corporation (where the Corporation is not the surviving corporation or where there is a change in or distribution with respect to the Common Stock of the Corporation), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock of the Corporation, then the Holder shall have the right thereafter to receive upon exercise of this Warrant, the number of shares of Common Stock of the successor or acquiring corporation or of the Corporation, if it is the surviving corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event. In case of any such reorganization, reclassification, merger, consolidation or disposition of assets, the successor or acquiring corporation (if other than the Corporation) shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Corporation and all the obligations and liabilities hereunder, subject to such modifications as may be deemed appropriate (as determined in good faith by resolution of the Board of Directors of the Corporation) in order to provide for adjustments of Warrant Shares for which this Warrant is exercisable which shall be as nearly equivalent as practicable to the adjustments provided for in this Section. For purposes of this Section, “common stock of the successor or acquiring corporation” shall include stock of such corporation of any class which is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this Section shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets.

Voluntary Adjustment by the Corporation. If and whenever at any time after the date hereof and prior to the Expiration Date, the Corporation takes any action affecting its Common Stock to which the foregoing provisions of this Section, in the opinion of the Board of Directors of the Corporation, acting reasonably and in good faith, are not strictly applicable, or if strictly applicable would not fairly adjust the rights of the Holder against dilution in accordance with the intent and purposes thereof, or would otherwise materially affect the rights of the Holder hereunder, then the Corporation shall execute and deliver to the Holder an amendment hereto providing for an adjustment in the application of such provisions so as to adjust such rights as aforesaid in such a manner as the Board of Directors of the Corporation may determine to be equitable in the

circumstances, acting reasonably and in good faith. Without limiting the generality of the foregoing, the Corporation may at any time during the term of this Warrant reduce the then current Purchase Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Corporation.

Notice of Adjustment. Whenever the number of Warrant Shares or number or kind of securities or other property purchasable upon the exercise of this Warrant or the Purchase Price is adjusted, as herein provided, the Corporation shall give notice thereof to the Holder, which notice shall state the number of Warrant Shares (and other securities or property) purchasable upon the exercise of this Warrant and the Purchase Price of such Warrant Shares (and other securities or property) after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made.

Notice of Corporate Action. If at any time:

the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, or

there shall be any capital reorganization of the Corporation, any reclassification or recapitalization of the capital stock of the Corporation or any consolidation or merger of the Corporation with, or any sale, transfer or other disposition of all or substantially all the property, assets or business of the Corporation to, another corporation, or

there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation;

then, in any one or more of such cases, the Corporation shall give to Holder (i) at least 20 days’ prior written notice of the date on which a record date shall be selected for such dividend or distribution, or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, liquidation or winding up, and (ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, at least 20 days’ prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the purpose of such dividend or distribution, the date on which the holders of Common Stock shall be entitled to any such dividend or distribution, and the amount and character thereof, and (ii) the date on which any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if any such time is to be fixed, as of which the Holders of shall be entitled to exchange their Warrant Shares for securities or other property deliverable upon such disposition, dissolution, liquidation or winding up. Each such written notice shall be sufficiently given if addressed to Holder at the last address of Holder appearing on the books of the Corporation.
