3.    Exercise of Warrant.
(a)    Exercise Procedure.  This Warrant may be exercised from time to time on any Business Day during the Exercise Period, for all or any part of the unexercised Warrant Shares, upon:
(i)    surrender of this Warrant to the Company at its then principal executive offices (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction), together with an Exercise Agreement in the form attached hereto as Exhibit A (each, an “Exercise Agreement”), duly completed (including specifying the number of Warrant Shares to be purchased) and executed; and
(ii)    payment to the Company of the Aggregate Exercise Price in accordance with Section 3(b) or completion of a cashless exercise in accordance with Section 3(c).
(b)    Payment of the Aggregate Exercise Price.  At the option of the Holder, payment of the Aggregate Exercise Price for any exercise of this Warrant shall be made (i) by delivery to the Company of a certified or official bank check payable to the order of the Company, (ii) by wire transfer of immediately available funds to an account designated in writing by the Company, (iii) by cashless exercise as provided in Section 3(c) below, or (iv) by any permissible combination of such methods, in the amount of such Aggregate Exercise Price.
(c)    Cashless Exercise. This Warrant may be exercised at the Holder’s election, in whole or in part, by means of a “cashless exercise” in which the Holder shall be 

- 3 -




entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:
(A)    =    the Fair Market Value of one share of Common Stock as of the Trading Day immediately preceding the date of such exercise;
(B)     =     the Exercise Price, as adjusted hereunder; and 
(X)     =     the number of shares of Common Stock that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.
Notwithstanding anything to the contrary herein or in the Purchase Agreement, the Holder agrees that the Holder’s ability to elect a cashless exercise represents the sole and exclusive monetary remedy of the Holder for a registration default with respect to the Warrant Shares, and in no event shall the Company be required to satisfy the Warrant through net cash settlement.
(d)    Delivery of Stock Certificates.  Upon receipt by the Company of the Exercise Agreement, surrender of this Warrant and payment of the Aggregate Exercise Price (in accordance with Section 3(a) hereof), the Company shall, as promptly as practicable, execute (or cause to be executed) and deliver (or cause to be delivered) to the Holder a certificate or certificates representing the Warrant Shares issuable upon such exercise, together with cash in lieu of any fraction of a share, as provided in Section 3(e)  hereof.  The stock certificate or certificates so delivered shall be, to the extent possible, in such denomination or denominations as the exercising Holder shall reasonably request in the Exercise Agreement and shall be registered in the name of the Holder or, subject to compliance with Section 5 below, such other Person’s name as shall be designated in the Exercise Agreement.  This Warrant shall be deemed to have been exercised and such certificate or certificates of Warrant Shares shall be deemed to have been issued, and the Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares for all purposes, as of the Exercise Date.
(e)    Fractional Shares.  The Company shall not be required to issue a fractional Warrant Share upon exercise of any Warrant.  As to any fraction of a Warrant Share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash (by delivery of a certified or official bank check or by wire transfer of immediately available funds) equal to the product of (i) such fraction multiplied by (ii) the Fair Market Value of one Warrant Share on the Exercise Date.
(f)    Valid Issuance of Warrant and Warrant Shares; Payment of Taxes.  With respect to the exercise of this warrant, the Company hereby represents, covenants and agrees:
(i)    This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.

- 4 -




(ii)    All Warrant Shares issuable upon the exercise of this Warrant pursuant to the terms hereof shall be, upon issuance, and the Company shall take all such actions as may be necessary or appropriate in order that such Warrant Shares are, validly issued, fully paid and non-assessable, issued without violation of any preemptive or similar rights of any stockholder of the Company and free and clear of all taxes, liens and charges.
(iii)    The Company shall take all such actions as may be necessary to ensure that all such Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares may be listed at the time of such exercise (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance).
(iv)    The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of Warrant Shares upon exercise of this Warrant; provided, that the Company shall not be required to pay any tax or governmental charge that may be imposed with respect to any applicable withholding or the issuance or delivery of the Warrant Shares to any Person other than the Holder, and no such issuance or delivery shall be made unless and until the Person requesting such issuance has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid.
(g)    Conditional Exercise.  Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a public offering or a sale of the Company (pursuant to a merger, sale of stock, or otherwise), such exercise may at the election of the Holder be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.
(h)    Reservation of Shares.  During the Exercise Period, the Company shall at all times reserve and keep available out of its authorized but unissued Common Stock or other securities constituting Warrant Shares, solely for the purpose of issuance upon the exercise of this Warrant, the maximum number of Warrant Shares issuable upon the exercise of this Warrant, and the par value per Warrant Share shall at all times be less than or equal to the applicable Exercise Price.  The Company shall not increase the par value of any Warrant Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, and 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.
4.    Adjustment to Exercise Price and Number of Warrant Shares.  In order to prevent dilution of the purchase rights granted under this Warrant, the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 4.
(a)    Adjustment to Exercise Price and Warrant Shares Upon Dividend, Subdivision or Combination of Common Stock.  If the Company shall, at any time or from 

- 5 -




time to time after the Original Issue Date, (i) pay a dividend or make any other distribution upon the Common Stock or any other capital stock of the Company payable in shares of Common Stock, or (ii) subdivide (by any stock split, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to any such dividend, distribution or subdivision shall be proportionately reduced and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately increased.  If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately decreased.  Any adjustment under this Section 4(a) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.
(b)    Adjustment to Exercise Price and Warrant Shares Upon Reorganization, Reclassification, Consolidation or Merger.  In case the Company after the date hereof (a) shall consolidate with or merge into any other Person and shall not be the continuing or surviving corporation of such consolidation or merger, or (b) shall permit any other Person to consolidate with or merge into the Company and the Company shall be the continuing or surviving Person but, in connection with such consolidation or merger, the Common Stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (c) shall transfer all or substantially all of its properties or assets to any other Person, then, and in the case of each such transaction, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, this Warrant shall be terminated upon the consummation of the transaction and the holder of this Warrant shall be entitled to receive upon such consummation, in the same form of consideration as received by the shareholders, the excess, if any, of (i) the fair market value of the securities, cash or other property to which such holder would actually have been entitled as a shareholder upon such consummation if such holder had exercised the rights represented by this Warrant immediately prior thereto, less (ii) the aggregate exercise price payable upon exercise in full of this Warrant.
(c)    Certificate as to Adjustment.
(i)    As promptly as reasonably practicable following any adjustment of the Exercise Price, the Company shall furnish to the Holder a certificate of an executive officer setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof.
(ii)    As promptly as reasonably practicable following the receipt by the Company of a written request by the Holder, the Company shall furnish to the Holder a certificate of an executive officer certifying the Exercise Price then in effect and the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of the Warrant.

- 6 -




(d)    Notices.  In the event:
(i)    that the Company shall take a record of the holders of its Common Stock (or other capital stock or securities at the time issuable upon exercise of the Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, to vote at a meeting (or by written consent), to receive any right to subscribe for or purchase any shares of capital stock of any class or any other securities, or to receive any other security; or
(ii)    of any capital reorganization of the Company, any reclassification of the Common Stock of the Company, any consolidation or merger of the Company with or into another Person, or sale of all or substantially all of the Company’s assets to another Person; or
(iii)    of the voluntary or involuntary dissolution, liquidation or winding-up of the Company;
then, and in each such case, the Company shall send or cause to be sent to the Holder at least fifteen (15) days prior to the applicable record date or the applicable expected effective date, as the case may be, for the event, a written notice specifying, as the case may be, (A) the record date for such dividend, distribution, meeting or consent or other right or action, and a description of such dividend, distribution or other right or action to be taken at such meeting or by written consent, or (B) the effective date on which such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up is proposed to take place, and the date, if any is to be fixed, as of which the books of the Company shall close or a record shall be taken with respect to which the holders of record of Common Stock (or such other capital stock or securities at the time issuable upon exercise of the Warrant) shall be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to the Warrant and the Warrant Shares.
5.    Transfer of Warrant.  Subject to the transfer conditions referred to in the legend endorsed hereon and the terms and conditions of this Warrant and all rights hereunder are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant to the Company at its then principal executive offices with a properly completed and duly executed Assignment in the form attached hereto as Exhibit B, together with funds sufficient to pay any transfer taxes described in Section 3(f)(iv) in connection with the making of such transfer.  Upon such compliance, surrender and delivery and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled.
6.    Holder Not Deemed a Stockholder; Limitations on Liability.  Except as otherwise specifically provided herein, prior to the issuance to the Holder of the Warrant Shares to which the Holder is then entitled to receive upon the due exercise of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the 

- 7 -




Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, as such, 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.  In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.
7.    Replacement on Loss; Division and Combination.
(a)    Replacement of Warrant on Loss.  Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and upon delivery of an indemnity reasonably satisfactory to it (it being understood that a written indemnification agreement or affidavit of loss of the Holder shall be a sufficient indemnity) and, in case of mutilation, upon surrender of such Warrant for cancellation to the Company, the Company at its own expense shall execute and deliver to the Holder, in lieu hereof, a new Warrant of like tenor and exercisable for an equivalent number of Warrant Shares as the Warrant so lost, stolen, mutilated or destroyed; provided, that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Company for cancellation.
(b)    Division and Combination of Warrant.  Subject to compliance with the applicable provisions of this Warrant as to any transfer or other assignment which may be involved in such division or combination, this Warrant may be divided or, following any such division of this Warrant, subsequently combined with other Warrants, upon the surrender of this Warrant or Warrants to the Company at its then principal executive offices, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the respective Holders or their agents or attorneys.  Subject to compliance with the applicable provisions of this Warrant as to any transfer or assignment which may be involved in such division or combination, the Company shall at its own expense execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants so surrendered in accordance with such notice.  Such new Warrant or Warrants shall be of like tenor to the surrendered Warrant or Warrants and shall be exercisable in the aggregate for an equivalent number of Warrant Shares as the Warrant or Warrants so surrendered in accordance with such notice.
8.    No Impairment.  The Company shall not, by amendment of its Certificate of Incorporation or Bylaws, 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 to be observed or performed by it hereunder, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder in order to protect the exercise rights of the Holder against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

(a)    Agreement to Comply with the Securities Act; Legend.  The Holder, by acceptance of this Warrant, agrees to comply in all respects with the provisions of this Section 9 and the restrictive legend requirements set forth on the face of this Warrant and further agrees that such Holder shall not offer, sell or otherwise dispose of this Warrant or any Warrant Shares to be issued upon exercise hereof except under circumstances that will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”).  This Warrant and all Warrant Shares issued upon exercise of this Warrant (unless registered under the Securities Act) shall be stamped or imprinted with a legend in substantially the following form:
“THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR QUALIFIED UNDER ANY STATE OR FOREIGN SECURITIES LAWS AND MAY NOT BE OFFERED FOR SALE, SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED OR ASSIGNED UNLESS (I) A REGISTRATION STATEMENT COVERING SUCH SHARES IS EFFECTIVE UNDER THE ACT AND IS QUALIFIED UNDER APPLICABLE STATE AND FOREIGN LAW OR (II) THE TRANSACTION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS UNDER THE ACT AND THE QUALIFICATION REQUIREMENTS UNDER APPLICABLE STATE AND FOREIGN LAW AND, IF THE CORPORATION REQUESTS, AN OPINION SATISFACTORY TO THE CORPORATION TO SUCH EFFECT HAS BEEN RENDERED BY COUNSEL.”

(i)    The Holder is an “accredited investor” as defined in Rule 501 of Regulation D promulgated under the Securities Act.  The Holder is acquiring this Warrant and the Warrant Shares to be issued upon exercise hereof for investment for its own account and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act.
(ii)    The Holder understands and acknowledges that this Warrant and the Warrant Shares to be issued upon exercise hereof are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that, under such laws and applicable regulations, such securities may be resold without registration under the Securities Act only in certain limited circumstances.  In addition, the Holder represents that it is familiar with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

The Company may deem and treat the Person in whose name the Warrant is registered on such register as the Holder thereof for all purposes, and the Company shall not be affected by any notice to the contrary, except any assignment, division, combination or other transfer of the Warrant effected in accordance with the provisions of this Warrant.

Notwithstanding the foregoing, the Holder may, in its sole discretion, agree to any consent, approval, action, termination, amendment or waiver that solely effects the rights of the Holder under this Warrant.  No failure or delay by any party in exercising any power or right arising from this Warrant 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.
