In order to exercise this Warrant, in whole or in part, the Holder shall deliver to the Company at its principal office or at the office or agency designated by the Company pursuant to Section I, (i) a written notice of Holder's election to exercise this Warrant, which notice shall specify the number of Warrant Shares to be purchased, (ii) payment of the Warrant Price as provided herein, and (iii) this Warrant. Such notice shall be substantially in the form of the subscription form (the "SUBSCRIPTION FORM") appearing at the end of this Warrant as Exhibit A, duly executed by the Holder or its agent or attorney. Upon receipt thereof, the Company shall, as promptly as reasonably practicable, and in any event within five (5) Business Days thereafter (the "DELIVERY PERIOD"), execute or cause to be executed and deliver or cause to be delivered to the Holder a certificate or certificates representing the aggregate number of Warrant Shares issuable upon such exercise, together with cash in lieu of any fraction of a share, as hereinafter provided. The stock certificate or certificates so delivered shall be in such denomination or denominations as the Holder may reasonably request in the notice and shall be registered in the name of the Holder or such other name as shall be designated in the notice and, following the date on which the Warrant Shares have been sold and transferred pursuant to an effective resale registration statement filed with the Commission or otherwise may be sold by the Holder pursuant to Rule 144(k) promulgated under the Securities Act (or a successor rule), shall not bear any restrictive legend. This Warrant shall be deemed to have been exercised and such certificate or certificates 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 shares for all purposes, as of the date when the notice, together with the payment of the Warrant Price and this Warrant, is received by the Company as described above. If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased shares of Common Stock called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or at the request of the Holder, appropriate notation may be made on this Warrant and the same returned to the Holder. iii. Payment of the Warrant Price may be made at the option of the Holder by: (i) certified or official bank check payable to the order of the Company, or (ii) wire transfer to the account of the Company. All shares of Common Stock issuable upon the exercise of this Warrant pursuant to the terms hereof shall be validly issued and, upon payment of the Warrant Price, shall be fully paid and nonassessable and not subject to any preemptive rights. The Company shall pay all expenses in connection with, and all transfer, stamp or similar taxes and other governmental charges that may be imposed with respect to, the issue or delivery thereof, provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer -4- involved in the issuance of any certificates for Warrant Shares or Warrants in a name other than the name of the Holder. iv. Prior to the exercise of this Warrant, the Holder shall not be entitled to any rights as a stockholder of the Company with respect to the Warrant Shares, including, without limitation, the right to vote such Warrant Shares, receive dividends or other distributions thereon or to be notified of stockholder meetings, except as set forth herein. v. If the Company's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend (pursuant to the terms of that certain Preferred Stock and Warrant Purchase Agreement, dated September 10, 2003, by and among the Company and the signatories thereto (the "PURCHASE AGREEMENT"), the Company shall cause its transfer agent to electronically transmit the Warrant Shares so purchased to the Holder or the Holder's designee by crediting the account of the Holder or the Holder's designee or its respective nominee with DTC through its Deposit Withdrawal Agent Commission system ("DTC TRANSFER"). If the aforementioned conditions to a DTC Transfer are not satisfied, the Company shall deliver to the Holder or the Holder's designee physical certificates representing the Warrant Shares so purchased. Notwithstanding the foregoing, the Holder or the Holder's designee may instruct the Company to deliver to the Holder or such designee physical certificates representing the Warrant Shares so purchased in lieu of delivering such shares by way of DTC Transfer. vi. If, at any time, a Holder of this Warrant submits this Warrant, a Subscription Form and payment to the Company of the Exercise Price for each of the Warrant Shares specified in the Subscription Form (including pursuant to a Cashless Exercise), and the Company fails for any reason (other than the reasons contemplated by Section 2.a hereof) to deliver, on or prior to the fourth business day following the expiration of the Delivery Period for such exercise, the number of shares of Common Stock to which the Holder is entitled upon such exercise (an "EXERCISE DEFAULT"), then the Company shall pay to the Holder payments ("EXERCISE DEFAULT PAYMENTS") for an Exercise Default in the amount of (i) (N/365), multiplied by (ii) the amount by which the Market Price of the Common Stock on the date the Exercise Agreement giving rise to the Exercise Default is transmitted in accordance with this Section 2 (the "EXERCISE DEFAULT DATE") exceeds the Exercise Price in respect of such Warrant Shares, multiplied by (iii) the number of shares of Common Stock the Company failed to so deliver in such Exercise Default, multiplied by (iv) .24, where N equals the number of days from the Exercise Default Date to the date that the Company effects the full exercise of this Warrant which gave rise to the Exercise Default. The accrued Exercise Default Payment for each calendar month shall be paid in cash and shall be made to the Holder by the fifth day of the month following the month in which it has accrued. Nothing herein shall limit the Holder's right to pursue actual damages for the Company's failure to maintain a sufficient number of authorized shares of Common Stock as required pursuant to the terms of Section 6 hereof or to otherwise issue shares of Common Stock upon exercise of this Warrant in accordance with the terms hereof, and the Holder shall have the right to pursue all remedies available at law or in equity (including a decree of specific performance and/or injunctive relief). -5- b. Restrictions on Exercise Amount. Notwithstanding any contrary or inconsistent provision hereof, the Holder may not acquire a number of Warrant Shares to the extent that, upon such exercise, the number of shares of Common Stock then owned of record by such Holder and its Affiliates and any other Persons or entities whose record ownership of Common Stock would be aggregated with the Holder's for purposes of Section 13(d) of the Exchange Act (including shares held by any "group" of which the Holder is a member) exceeds 4.95% of the total number of shares of Common Stock then issued and outstanding (such limitation being herein referred to as the "BENEFICIAL OWNERSHIP CAP"). For purposes hereof, "group" has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Commission, and the percentage held by the Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. The restriction contained in this Section 2.b may not be altered, amended, deleted or changed in any manner whatsoever unless the holders of a majority of the outstanding shares of Common Stock and the Holder hereof shall approve, in writing, such alteration, amendment, deletion or change. 3. TRANSFER, DIVISION AND COMBINATION. a. Transfer. The Warrants and the Warrant Shares may not be transferred or assigned in whole or in part without compliance with all applicable federal and state securities laws by the transferor and the transferee (including the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, if such are requested by the Company; provided that such letters and legal opinions shall not be unreasonably requested with respect to a transfer to an Affiliate of the Holder) and any stockholders agreement to which the transferor is a party. Subject to the foregoing, Transfer of this Warrant and all rights hereunder, in whole or in part, shall be registered on the books of the Company to be maintained for such purpose, upon surrender of this Warrant at the principal office of the Company referred to in Section 10.b or the office or agency designated by the Company pursuant to Section 9, together with a written assignment of this Warrant substantially in the form of Exhibit B hereto 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. 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 and in the denomination specified in such instrument of assignment, 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. The acceptance of the new Warrant or Warrants by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a Holder. Following a transfer that complies with the requirements of this Section 3.a, the Warrant may be exercised by a new Holder for the purchase of shares of Common Stock regardless of whether the Company issued or registered a new Warrant on the books of the Company. b. Prohibited Transfers. Notwithstanding anything to the contrary herein, the Holder shall at all times be prohibited from transferring any Warrant and any Warrant Shares to any Person who, at the time of such determination, is currently engaging, or is reasonably likely to engage, in the same or a substantially similar business as that of the Company. -6- c. Restrictive Legend. Each certificate for Warrant Shares initially issued upon the exercise of this Warrant unless such Warrant Shares may otherwise be sold by the Holder pursuant to Rule 144(k) promulgated under the Securities Act (or a successor rule), each certificate for Warrant Shares issued to any subsequent transferee of any such certificate, shall be stamped or otherwise imprinted with a legend in substantially the following form: "THE SECURITIES REPRESENTED BY, OR ACQUIRABLE UPON CONVERSION OR EXERCISE OF SECURITIES EVIDENCED BY, THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT UNLESS THE ISSUER OF THIS CERTIFICATE RECEIVES AN OPINION OF LEGAL COUNSEL REASONABLY ACCEPTABLE TO THE ISSUER AND ITS LEGAL COUNSEL THAT SUCH SALE IS EXEMPT FROM REGISTRATION UNDER SUCH ACT AND IS IN COMPLIANCE WITH APPLICABLE STATE SECURITIES OR BLUE SKY LAWS UNLESS SUCH REGISTRATION IS NOT REQUIRED." d. Division and Combination; Expenses; Books. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office or agency 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 3.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. The Company shall prepare, issue and deliver at its own expense the new Warrant or Warrants under this Section 3. The Company agrees to maintain, at its aforesaid office or agency, books for the registration and the registration of transfer of the Warrants. 4. ADJUSTMENTS. The number of shares of Common Stock for which this Warrant is exercisable, and the Exercise Price, shall be subject to adjustment from time to time as set forth in this Section 4. The Company shall give the Holder notice of any event described below which requires an adjustment pursuant to this Section 4 in accordance with Sections 5.a and 5.b. a. Stock Dividends, Subdivisions and Combinations. If at any time while this Warrant is outstanding the Company shall: i. take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend payable in, or other distribution of, additional shares of Common Stock, -7- ii. subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, or iii. combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then: (1) the number of shares of Common Stock acquirable upon exercise of this Warrant immediately after the occurrence of any such event shall be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock that would have been acquirable under this Warrant immediately prior to the occurrence of such event would own or be entitled to receive after the happening of such event, and (2) the Exercise Price shall be adjusted to equal: (A) the Exercise Price in effect immediately prior to the occurrence of such event multiplied by the number of shares of Common Stock into which this Warrant is exercisable immediately prior to the adjustment, divided by (B) the number of shares of Common Stock into which this Warrant is exercisable immediately after such adjustment. Any adjustment made pursuant to clause (i) of this Section 4.a 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 clauses (ii) or (iii) of this Section 4.a shall become effective immediately after the effective date of such subdivision or combination. b. Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. i. If, during the Exercise Period, there shall occur a Change of Control and, pursuant to the terms of such Change of Control, 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, then the Holder shall have the right thereafter to receive, upon the exercise of the Warrant, the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and the Other Property receivable upon or as a result of such Change of Control by a holder of the number of shares of Common Stock into which this Warrant is exercisable immediately prior to such event. ii. In case of any such Change of Control, the successor or acquiring corporation (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every covenant and condition contained in this Warrant to be performed and observed by the Company and all the obligations and liabilities hereunder, subject to such modifications as may be deemed appropriate (as determined by resolution of the Board of Directors of -8- the Company) in order to provide for adjustments of shares of the Common Stock into which this Warrant is exercisable which shall be as nearly equivalent as practicable to the adjustments provided for in this Section 4. c. Other Action Affecting Common Stock. In case at any time or from time to time the Company shall take any action in respect of its Common Stock, then, unless such action will not have a materially adverse effect upon the rights of the Holder, the number of shares of Common Stock or other stock into which this Warrant is exercisable and/or the Exercise Price shall be adjusted in such manner as may be equitable in the circumstances. d. Certain Limitations. Notwithstanding anything herein to the contrary, the Company agrees not to enter into any transaction which, by reason of any adjustment hereunder, would cause the Exercise Price to be less than the par value per share of Common Stock. e. Stock Transfer Taxes. The issue of stock certificates upon exercise of this Warrant shall be made without charge to the Holder for any tax in respect of such issue. f. Fractional Interests. The Company shall not be required to issue a fractional share of Common Stock upon exercise of any Warrant. If an adjustment made pursuant to this Section 4 entitles the Holder to any fraction of a share, such fraction shall be rounded to the nearest whole number and the Holder shall be entitled to that number of shares. 5. NOTICES TO WARRANT HOLDERS. a. Certificate as to Adjustments. Upon the occurrence, if any, of each adjustment or readjustment of the Exercise Price, or the number of shares of Common Stock and the amount, if any of Other Property which at the time would be received upon exercise of the Warrants owned by such Holder, the Company, at its expense, shall promptly 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 and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the reasonable written request at any time of the Holder, furnish or cause to be furnished to such Holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Exercise Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, or Other Property which at the time would be received upon the exercise of Warrants owned by such Holder. b. Notice of Corporate Action. If at any time: i. the Company 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 any right to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any other right, or ii. there shall be any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of the Company with, or any sale, transfer or other -9- disposition of all or substantially all the property, assets or business of the Company to, another corporation, or iii. there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company; then, in any one or more of such cases, the Company shall give to the Holder (i) at least 15 days' prior written notice of the record date that shall be selected for such dividend, distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, 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 15 days' prior written notice of the date when the same shall take place.

Each such written notice shall be sufficiently given if addressed to the Holder at the last address of the Holder appearing on the books of the Company and delivered in accordance with Section 10.b. The failure to give any notice required by this Section 5.b shall not invalidate any such corporate action. c. Notice to Stockholders.

Subject to the foregoing, the Holder, as such, shall not be entitled to vote or receive dividends or be deemed the holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, 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 of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised as provided herein. 6.

TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS.

The Company will not at any time, except upon dissolution, liquidation or winding up of the Company, close its stock transfer books or Warrant transfer books so as to result in preventing or delaying the exercise or transfer of any Warrant. 8.

Applicants for a replacement Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable charges as the Company may prescribe. 9. OFFICE OF THE COMPANY. As long as any of the Warrants remain outstanding, the Company shall maintain an office or agency (which may be the principal executive offices of the Company) where the Warrants may be presented for exercise, registration of transfer, division or combination as provided in this Warrant. 10. MISCELLANEOUS. a. Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of the Holder shall operate as a waiver of such right or otherwise prejudice Holder's rights, powers or remedies.
