"After-Tax Basis" when referring to a payment that is required hereunder (the "target amount"), means a total payment (the "total amount") that, after deduction of all federal, state and local taxes that are required to be paid by the recipient in respect of the receipt or accrual of such total amount, is equal to the target amount.

If the amount to be appraised is less than or equal to five hundred thousand dollars ($500,000), the Valuation Amount shall be determined in good faith by the Board of Directors of the Company (the "Board of Directors"). If the amount to be appraised is greater than five hundred thousand dollars ($500,000), the Valuation Amount shall be determined in good faith jointly by the Board of Directors and the holders of more than 50% of the issued and outstanding shares of Series D Preferred Stock; provided, however, that any holder of Series D Preferred Stock having a Liquidation Preference greater than five hundred thousand dollars ($500,000) (an “Appraisal Rights Holder”) shall be promptly notified by the Board of Directors of such initially determined Valuation Amount and if such Appraisal Rights Holder notifies the Company that it does not agree on the Valuation Amount within a reasonable period of time (not to exceed twenty (20) days from the notice to the Appraisal Rights Holder), the Valuation Amount shall be determined by an investment banking firm of national recognition, which firm shall be reasonably acceptable to the Board of Directors and the Appraisal Rights Holder. If the Board of Directors and the Appraisal Rights Holder are unable to agree upon an acceptable investment banking firm within ten (10) days after the date either party proposed that one be selected, the investment banking firm will be selected by an arbitrator located in New York, New York, selected by the New York branch of the American Arbitration Association (or if such organization ceases to exist, the arbitrator shall be chosen by a court of competent jurisdiction). The arbitrator shall select the investment banking firm (within ten (10) days of his appointment) from a list, jointly prepared by the Board of Directors and the Appraisal Rights Holder, of not more than six investment banking firms of national standing in the United States, of which no more than three may be named by the Board of Directors and no more than three may be named by the Appraisal Rights Holder. The arbitrator may consider, within the ten-day period allotted, arguments from the parties regarding which investment banking firm to choose, but the selection by the arbitrator shall be made in its sole discretion from the list of six. The Board of Directors and the Appraisal Rights Holder shall submit their respective valuations and other relevant data to the investment banking firm, and the investment banking firm shall, within thirty days of its appointment, make its own determination of the Valuation Amount. The final Valuation Amount for purposes hereof shall be the average of the two Valuation Amounts closest together, as determined by the investment banking firm, from among the Valuation Amounts submitted by the Company and the Appraisal Rights Holder and the Valuation Amount calculated by the investment banking firm. The determination of the final Valuation Amount by such investment-banking firm shall be final and binding upon the parties. The Company shall pay the fees and expenses of the investment banking firm and arbitrator (if any) used to determine the Valuation Amount. If required by any such investment banking firm or arbitrator, the Company shall execute a retainer and engagement letter containing reasonable terms and conditions, including, without limitation, customary provisions concerning the rights of indemnification and contribution by the Company in favor of such investment banking firm or arbitrator and its officers, directors, partners, employees, agents and affiliates.

EXERCISE OF WARRANT
 
2.1  Manner of Exercise.
 
(a)  From and after the Issue Date and at any time before 5:00 P.M., New York time, on the Expiration Date, the Holder of this Warrant may from time to time exercise this Warrant, on any Business Day, for all or any part of the number of shares of Warrant Stock (subject to adjustment as provided herein) purchasable hereunder. In order to exercise this Warrant, in whole or in part, the Holder shall (i) deliver to the Company at its Designated Office a written notice of the Holder's election to exercise this Warrant (an "Exercise Notice") substantially in the form attached to this Warrant as Annex A (or a reasonable facsimile thereof), which Exercise Notice shall be irrevocable and specify the number of shares of Warrant Stock to be purchased, together with this Warrant and (ii) pay to the Company the Warrant Price. The date on which such delivery and payment shall have taken place being hereinafter sometimes referred to as the "Exercise Date."
 
(b)  Upon receipt by the Company of such Exercise Notice, surrender of this Warrant and payment of the Warrant Price (in accordance with Section 2.1(c) hereof), the Company shall, as promptly as practicable, and in any event within three (3) Business Days thereafter, execute (or cause to be executed) and deliver (or cause to be delivered) to the Holder a certificate or certificates representing the shares of Warrant Stock issuable upon such exercise, together with cash in lieu of any fraction of a share, as hereafter provided. 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 Notice and shall be registered in the name of the Holder or, subject to compliance with Section 3.1 below, such other name as shall be designated in the Exercise Notice. This Warrant shall be deemed to have been exercised and such certificate or certificates of Warrant Stock 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 of Warrant Stock for all purposes, as of the Exercise Date.
 
(c)  Payment of the Warrant Price shall be made at the option of the Holder by one or more of the following methods: (i) by delivery of a certified or official bank check or by wire transfer of immediately available funds in the amount of such Warrant Price payable to the order of the Company, (ii) by instructing the Company to withhold a number of shares of Warrant Stock then issuable upon exercise of this Warrant with an aggregate Fair Market Value equal to such Warrant Price, (iii) by surrendering to the Company (x) shares of Series D Preferred Stock previously acquired by the Holder with an aggregate Fair Market Value equal to such Warrant Price and/or (y) shares of Series D Preferred Stock with an aggregate Liquidation Preference (as such term is defined in the Series D Certificate of Designation) equal to such Warrant Price, or (iv) any combination of the foregoing. In the event of any withholding of Warrant Stock or surrender of Common Stock and/or Series D Preferred Stock pursuant to clause (ii), (iii) or (iv) above where the number of shares whose Fair Market Value is equal to the Warrant Price is not a whole number, the number of shares withheld by or surrendered to the Company shall be rounded up to the nearest whole share and the Company shall make a cash payment to the Holder based on the incremental fraction of a share being so withheld by or surrendered to the Company in an amount determined in accordance with Section 2.3 hereof.
 
(d)  If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing the shares of Warrant Stock being issued, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased shares of Warrant Stock called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.
 
(e)  All Warrants delivered for exercise shall be canceled by the Company.
 
2.2  Payment of Taxes. All shares of Warrant Stock issuable upon the exercise of this Warrant pursuant to the terms hereof shall be validly issued, fully paid and nonassessable, issued without violation of any preemptive or similar rights of any stockholder of the Company and free and clear of all Liens. The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issue or delivery thereof, unless such tax or charge is imposed by law upon the Holder, in which case such taxes or charges shall be paid by the Holder and the Company shall reimburse the Holder therefor on an After-Tax Basis. The Company shall not, however, be required to pay any tax or governmental charge which may be issuable upon exercise of this Warrant payable in respect of any Transfer involved in the issue and delivery of shares of Warrant Stock in a name other than that of the holder of the Warrants to be exercised, and no such issue or delivery shall be made unless and until the Person request-ing such issue 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.
 
2.3  Fractional Shares. The Company shall not be required to issue a fractional share of Warrant Stock upon exercise of any Warrant. As to any fraction of a share that the Holder of one or more Warrants, the rights under which are exercised in the same transaction, would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash equal to such fraction multiplied by the Fair Market Value of one share of Series D Preferred Stock on the Exercise Date.
 
2.4  Company to Reaffirm Obligations. The Company will, at the time of each exercise of this Warrant, upon the request of the Holder, acknowledge in writing its continued obligation to afford to the Holder all rights (including without limitation, any rights to registration, pursuant to the Registration Rights Agreement entered into between the Company and the Holder of the Series D Preferred Stock or any other securities issued upon such exercise) to which the Holder shall continue to be entitled after such exercise in accordance with the terms of this Warrant, provided that if the Holder shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford such rights to the Holder.
 
 
3.  
TRANSFER, DIVISION AND COMBINATION
 
3.1  Compliance with Securities Act. The Holder, by acceptance hereof, agrees to comply in all respects with the provisions of this Section 3.1 and further agrees that this Warrant and the Warrant Stock to be issued upon exercise hereof are being acquired for investment for its own account and that such Holder will not offer, sell or otherwise dispose of this Warrant or any Warrant Stock to be issued upon exercise hereof except under circumstances that will not result in a violation of the Securities Act. This Warrant and all shares of Warrant Stock 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:
 
THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT.
 
            In addition, in connection with the issuance of this Warrant, the Holder specifically represents to the Company by acceptance of this Warrant as follows:
 
(a)  The Holder has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Warrant and the business, properties, prospects and financial condition of the Company. This does not limit or modify the representations and warranties of the Company in this Warrant or the right of the Holder to rely thereon.
 
(b)  The Holder understands that the securities it is purchasing are characterized as "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 SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.
 
(c)  The Holder acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Warrant and the Warrant Stock. The Holder also represents it has not been organized solely for the purpose of acquiring the Warrant and the Warrant Stock.
 
(d)  Prior to any proposed transfer of this Warrant or the Warrant Stock, unless there is in effect a registration statement under the Securities Act covering the proposed transfer, the Holder of such securities shall give written notice to the Company of such Holder's intention to effect such transfer. Each such notice shall describe the manner and circumstances of the proposed transfer in sufficient detail, and shall be accompanied by either (i) a written opinion, of legal counsel who shall be reasonably satisfactory to the Company, addressed to the Company and reasonably satisfactory, in form and substance, to the Company's counsel, to the effect that the proposed transfer of the Warrant and/or Warrant Stock may be effected without registration under the Securities Act, or (ii) a "no action" letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that enforcement action be taken with respect thereto, whereupon the Holder of such securities shall be entitled to transfer such securities in accordance with the terms of the notice delivered by the Holder to the Company.
 
(e)  The Holder, by acceptance of this Warrant, agrees to the restrictive legend requirements and transfer provisions contained in Section 8.13 of the Purchase Agreement, to the extent such provisions are applicable to this Warrant and the Warrant Stock held by the Holder.
 
3.2  Transfer. Each new certificate evidencing the Warrant and/or Warrant Stock so transferred shall bear the appropriate restrictive legends set forth in Section 3.1 hereof, except that such certificate shall not bear such restrictive legend, if, in the opinion of counsel for the Company, such legend is not required in order to establish or assist in compliance with any provisions of the Securities Act or any applicable state securities laws. Upon compliance with the provisions of this Section 3.2, each 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 Designated Office and compliance with the terms hereof, together with a written assignment of this Warrant in the form of Annex B hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes described in Section 2.2 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 not so assigned and this Warrant shall promptly be cancelled.
 
3.3  Mutilation or Loss. Upon receipt of evidence reasonably satisfac-tory 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 the written indemnification agreement of 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 will execute and deliver to the Holder, in lieu hereof a new Warrant of like tenor and exercisable for an equivalent number of shares of Series D Preferred Stock as the Warrant so lost, stolen, mutilated or destroyed; provided, however, that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Company for cancellation.
 
3.4  Division and Combination. Subject to compliance with the applicable provisions of this Warrant, this Warrant may be divided or combined with other Warrants upon presentation hereof at the Designated Office, 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 the applicable provisions of this Warrant 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.
 
3.5  Expenses. The Company shall prepare, issue and deliver at its own expense any new Warrant or Warrants required to be issued hereunder.
 
3.6  Maintenance of Books. The Company agrees to maintain, at the Desig-nated Office, books for the registration and transfer of the Warrants. The Company may treat the Person in whose name any Warrant is registered on such register as the Holder thereof for all other purposes, and the Company shall not be affected by any notice to the contrary, except that, if and when any Warrant is properly assigned in blank, the Company may (but shall not be obligated to) treat the bearer thereof as the owner of such Warrant for all purposes.

(i)  the Exercise Price in effect immediately prior to the issuance of such Series D Preferred Stock, options, rights or securities by
 
(ii)  a fraction of which (x) the numerator shall be the sum of (i) the number of shares of Series D Preferred Stock Outstanding on a fully-diluted basis immediately prior to such issuance and (ii) the number of additional shares of Series D Preferred Stock which the aggregate consideration for the number of shares of Series D Preferred Stock so offered would purchase at the Fair Market Value per share of Series D Preferred Stock and (y) the denominator shall be the number of shares of Series D Preferred Stock Outstanding on a fully-diluted basis immediately after such issuance.
 
4.2  Upon Acquisition of Series D Preferred Stock. If the Company or any Subsidiary shall, at any time or from time to time after the Issue Date, directly or indirectly, redeem, purchase or otherwise acquire any shares of Series D Preferred Stock, options to purchase or rights to subscribe for Series D Preferred Stock, securities by their terms convertible into or exchangeable for Series D Preferred Stock (other than shares of Series D Preferred Stock that are redeemed according to their terms), or options to purchase or rights to subscribe for such convertible or exchangeable securities, for a consideration per share greater than the Fair Market Value (plus, in the case of such options, rights, or securities, the additional consideration required to be paid to the Company upon exercise, conversion or exchange) per share of Series D Preferred Stock immediately prior to such event, then the Exercise Price shall forthwith be lowered to a price equal to the price obtained by multiplying:

(A)  
(1) the product of (a) the number of shares of Series D Preferred Stock Outstanding on a fully-diluted basis and (b) the Fair Market Value per share of Series D Preferred Stock, in each case immediately prior to such event, minus (2) the aggregate consideration paid by the Company in such event (plus, in the case of such options, rights, or convertible or exchangeable securities, the aggregate additional consideration to be paid by the Company upon exercise, conversion or exchange), by

(i)  In the case of the issuance of Series D Preferred Stock for cash in a public offering or private placement, the consideration shall be deemed to be the amount of cash paid therefor before deducting therefrom any discounts, commissions or placement fees payable by the Company to any underwriter or placement agent in connection with the issuance and sale thereof.
 
(ii)  In the case of the issuance of Series D Preferred Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the Fair Market Value thereof.

(A)  
the aggregate maximum number of shares of Series D Preferred Stock deliverable upon exercise of such options to purchase or rights to subscribe for Series D Preferred Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subparagraphs (i) and (ii) above), if any, received by the Company upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Series D Preferred Stock covered thereby;
 
(B)  
the aggregate maximum number of shares of Series D Preferred Stock deliverable upon conversion of or in exchange for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities, options, or rights were issued and for a consideration equal to the consideration received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Company upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in paragraphs (i) and (ii) above);

on any change in the number of shares or exercise price of Series D Preferred Stock deliverable upon exercise of any such options or rights or conversions of or exchanges for such securities, other than a change resulting from the anti-dilution provisions thereof, the Exercise Price shall forthwith be readjusted to such Exercise Price as would have been obtained had the adjustment made upon the issuance of such options, rights or securities not converted prior to such change or options or rights related to such securities not converted prior to such change been made upon the basis of such change;
 
(D)  
upon the expiration of any options to purchase or rights to subscribe for Series D Preferred Stock which shall not have been exercised, the Exercise Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if the only additional shares of Series D Preferred Stock issued were the shares of Series D Preferred Stock, if any actually issued upon the exercise of such options to purchase or rights to subscribe for Series D Preferred Stock, and the consideration received therefor was the consideration actually received by the Company for the issue of the options to purchase or rights to subscribe for Series D Preferred Stock that were exercised, plus the consideration actually received by the Company upon such exercise; and
 
(E)  
no further adjustment of the Exercise Price adjusted upon the issuance of any such options, rights, convertible securi-ties or exchangeable securities shall be made as a result of the actual issuance of Series D Preferred Stock on the exercise of any such rights or options or any conversion or exchange of any such securities.
 
4.4  Upon Stock Dividends, Subdivisions or Splits. If, at any time after the Issue Date, the number of shares of Series D Preferred Stock Outstanding is increased by a stock dividend payable in shares of Series D Preferred Stock or by a subdivision or split-up of shares of Series D Preferred Stock, then, following the record date for the determination of holders of Series D Preferred Stock entitled to receive such stock dividend, or to be affected by such subdivision or split-up, the Exercise Price shall be appropriately decreased by multiplying the Exercise Price by a fraction, the numerator of which is the number of shares of Series D Preferred Stock Outstanding immediately prior to such increase and the denominator of which is the number of shares of Series D Preferred Stock Outstanding immediately after such increase in Outstanding shares.
 
4.5  Upon Combinations or Reverse Stock Splits. If, at any time after the Issue Date, the number of shares of Series D Preferred Stock Outstanding is decreased by a combination or reverse stock split of the Outstanding shares of Series D Preferred Stock into a smaller number of shares of Series D Preferred Stock, then, following the record date to determine shares affected by such combination or reverse stock split, the Exercise Price shall be appropriately increased by multiplying the Exercise Price by a fraction, the numerator of which is the number of shares of Series D Preferred Stock Outstanding immediately prior to such decrease and the denominator of which is the number of shares of Series D Preferred Stock Outstanding immediately after such decrease in Outstanding shares.
 
4.6  Upon Reclassifications, Reorganizations, Consolidations or Mergers. In the event of any capital reorganization of the Company, any reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or any consolidation or merger of the Company with or into another Person (where the Company is not the surviving Person or where there is a change in or distribution with respect to the Series D Preferred Stock), each Warrant shall after such reorganization, reclassification, consolidation, or merger be exercisable for the kind and number of shares of stock or other securities or property of the Company or of the successor Person resulting from such consolidation or surviving such merger, if any, to which the holder of the number of shares of Series D Preferred Stock deliverable (immediately prior to the time of such reorganization, reclassification, consolidation or merger) upon exercise of such Warrant would have been entitled upon such reorganization, reclassification, consolidation or merger. The provisions of this clause shall similarly apply to successive reorganizations, reclassifications, consolidations, or mergers. The Company shall not effect any such reorganization, reclassification, consolidation or merger unless, prior to the consummation thereof, the successor Person (if other than the Company) resulting from such reorganization, reclassification, consolidation or merger, shall assume, by written instrument, the obligation to deliver to the Holders of the Warrant such shares of stock, securities or assets, which, in accordance with the foregoing provisions, such Holders shall be entitled to receive upon such conversion.
 
4.7  Deferral in Certain Circumstances. In any case in which the provisions of this Section 4 shall require that an adjustment shall become effective immediately after a record date of an event, the Company may defer until the occurrence of such event (a) issuing to the Holder of any Warrant exercised after such record date and before the occurrence of such event the shares of capital stock issuable upon such exercise by reason of the adjustment required by such event and issuing to such Holder only the shares of capital stock issuable upon such exercise before giving effect to such adjustments, and (b) paying to such Holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section 2.3 above; provided, however, that the Company shall deliver to such Holder an appropriate instrument or due bills evidencing such Holder's right to receive such additional shares or such cash.
 
4.8  Other Anti-Dilution Provisions. If the Company has issued or issues any securities at a pre-investment valuation (on a fully diluted basis) of the Company of not more than $70,000,000 (excluding the total proceeds received by the Company under the Purchase Agreement), containing provisions (including, without limitation, any of the terms of pricing, exercise price, anti-dilution and registration rights) which are more favorable than those set forth herein, the Company will make such provisions (or any more favorable portion thereof) available to the Holder and will use best efforts to enter into amendments necessary to confer such rights on the Holder .
 
4.9  Appraisal Procedure. In any case in which the provisions of this Section 4 shall necessitate that the Appraisal Procedure be utilized for purposes of determining an adjustment to the Exercise Price, the Company may defer until the completion of the Appraisal Procedure and the determination of the adjustment (1) issuing to the Holder of any Warrant exercised after the date of the event that requires the adjustment and before completion of the Appraisal Procedure and the determination of the adjustment, the shares of capital stock issuable upon such exercise by reason of the adjustment required by such event and issuing to such Holder only the shares of capital stock issuable upon such exercise before giving effect to such adjustment and (2) paying to such Holder any amount in cash in lieu of a fractional share of capital stock pursuant to Section 2.3 above; provided, however, that the Company shall deliver to such Holder an appropriate instrument or due bills evidencing such Holder's right to receive such additional shares or such cash.
 
4.10  Adjustment of Number of Shares Purchasable. Upon any and each adjustment of the Exercise Price as provided for in Section 4.1, 4.2, 4.4, 4.5 and 4.6, the Holders of the Warrants shall thereafter be entitled to purchase upon the exercise thereof, at the Exercise Price resulting from such adjustment, the number of shares of Warrant Stock (calculated to the nearest 1/100th of a share) obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares of Warrant Stock issuable on the exercise hereof immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment.
 
4.11  Notice of Adjustment of Exercise Price. Whenever the Exercise Price is adjusted as herein provided:
 
(i)  the Company shall compute the adjusted Exercise Price in accor-dance with this Section 4 and shall prepare a certificate signed by the treasurer or chief financial officer of the Company setting forth the adjusted Exercise Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at the Designated Office; and
 
(ii)  a notice stating that the Exercise Price has been adjusted and setting forth the adjusted Exercise Price shall forthwith be prepared by the Company, and as soon as practicable after it is prepared, such notice shall be mailed by the Company at its expense to all Holders at their last addresses as they shall appear in the warrant register.
 
 
5.  
NO IMPAIRMENT; REGULATORY COMPLIANCE AND COOPERATION; NOTICE OF EXPIRATION
 
5.1  The Company shall not by any action, including, without limitation, amending its charter documents or through any reorganization, reclassification, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other similar 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 the Holder against impairment. Without limiting the generality of the foregoing, the Company shall take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Warrant Stock upon the exercise of this Warrant, free and clear of all Liens, and shall use its best 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.
 
5.2  The Company shall deliver to each Holder of Warrants, after the 60th day but before the 30th day prior to the Expiration Date, advance notice of such Expiration Date. If the Company fails to fulfill in a timely manner the notice obligation set forth in the prior sentence, it shall provide such notice as soon as possible thereafter.
 
 
6.  
RESERVATION AND AUTHORIZATION OF SERIES D PREFERRED STOCK
 
6.1  The Company shall at all times reserve and keep available for issuance upon the exercise of the Warrants such number of its authorized but unissued shares of Series D Preferred Stock as will be required for issuance of the Warrant Stock. All shares of Warrant Stock issuable pursuant to the terms hereof, when issued upon exercise of this Warrant with payment therefor in accordance with the terms hereof, shall be duly and validly issued and fully paid and nonassessable, not subject to preemptive rights and shall be free and clear of all Liens. Before taking any action that would result in an adjustment in the number of shares of Warrant Stock 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 over such action. If any shares of Warrant Stock required to be reserved for issuance upon exercise of Warrants require registration or qualification with any Governmental Entity under any federal or state law (other than under the Securities Act or any state securities law) before such shares may be so issued, the Company will in good faith and as expeditiously as possible and at its expense endeavor to cause such shares to be duly registered.
 
6.2  Before taking any action that would cause an adjustment reducing the Exercise Price below the then par value (if any) of the shares of Warrant Stock deliverable upon exercise of the Warrant or that would cause the number of shares of Warrant Stock issuable upon exercise of the Warrant to exceed (when taken together with all other Outstanding shares of Series D Preferred Stock) the number of shares of Series D Preferred Stock that the Company is authorized to issue, the Company will take any corporate action that, in the opinion of its counsel, is necessary in order that the Company may validly and legally issue the full number of fully paid and nonassessable shares of Warrant Stock issuable upon exercise of the Warrant at such adjusted exercise price.

7.2  Taking of Record. In the case of all dividends or other distributions by the Company to the holders of its Series D Preferred Stock with respect to which any provision hereof refers to the taking of a record of such holders, the Company will in each such case take such a record and will take such record as of the close of business on a Business Day.
 
7.3  Closing of Transfer Books. The Company shall not at any time close its stock transfer books or warrant transfer books so as to result in preventing or delaying the exercise or transfer of any Warrant.

Such Designated Office shall initially be the office of the Company at Pennington Business Park, 55 Route 31 South, Pennington, NJ 08534.

10.  
DILUTION FEE
 
(a)  In the event that any dividends are declared or paid or any other distribu-tion is made on or with respect to the Series D Preferred Stock, the Holder of this Warrant as of the record date established by the Board of Directors for such dividend or distribution on the Common Stock shall be entitled to receive a fee (the "Dilution Fee") in an amount (whether in the form of cash, securities or other property) equal to the amount (and in the form) of the dividends or distribution that such Holder would have received had the Warrant been exercised as of the date immediately prior to the record date for such dividend or distribution, such Dilution Fee to be payable on the same payment date established by the Board of Directors for the payment of such dividend or distribution; provided, however, that if the Company declares and pays a dividend or distribution on the Series D Preferred Stock consisting in whole or in part of Series D Preferred Stock, then no such Dilution Fee shall be payable in respect of the Warrant on account of the portion of such dividend or distribution on the Series D Preferred Stock payable in Series D Preferred Stock and in lieu thereof the adjustment in Section 4 hereof shall apply. The record date for any such Dilution Fee shall be the record date for the applicable dividend or distribution on the Series D Preferred Stock, and any such Dilution Fee shall be payable to the Persons in whose name the Warrant is registered at the close of business on the applicable record date.
 
(b)  No dividend shall be paid or declared on any share of Series D Preferred Stock (other than dividends payable in Series D Preferred Stock for which an adjustment was made pursuant to Section 4 hereof), unless the Dilution Fee, payable in the same consideration and manner, is simultaneously paid or provided for, as the case may be, in respect of this Warrant in an amount determined as set forth above. For purposes hereof, the term "dividends" shall include any pro rata distribution by the Company, out of funds of the Company legally available therefor, of cash, property, securities (including, but not limited to, rights, warrants or options) or other property or assets to the holders of the Series D Preferred Stock, whether or not paid out of capital, surplus or earnings other than liquidation.
 
(c)  Prior to declaring any dividend or making any distribution on or with respect to shares of Series D Preferred Stock, the Company shall take all prior corporate action necessary to authorize the issuance of any securities payable as the Dilution Fee in respect of the Warrant.
 
 
11.  
MISCELLANEOUS
 
11.1  No Implied Waivers. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

11.3  Indemnification. If the Company fails to make, when due, any payments provided for in this Warrant, the Company shall pay to the Holder hereof (a) interest at the Agreed Rate on any amounts due and owing to such Holder and (b) such further amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys' fees and expenses incurred by such Holder in collecting any amounts due hereunder. The Company shall indemnify, save and hold harmless the Holder hereof and the Holders of any Warrant Stock issued upon the exercise hereof from and against any and all liability, loss, cost, damage, reasonable attorneys' and accountants' fees and expenses, court costs and all other out-of-pocket expenses incurred in connection with or arising from any default hereunder by the Company. This indemnification provision shall be in addition to the rights of such Holder or Holders to bring an action against the Company for breach of contract based on such default hereunder.
 
11.4  Limitation of Liability. No provision hereof, in the absence of affirmative action by the Holder to purchase shares of Warrant Stock, and no enumeration herein of the rights or privileges of the Holder hereof, shall give rise to any liability of such Holder to pay the Exercise Price for any Warrant Stock other than pursuant to an exercise of this Warrant or any liability as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. The Holder shall not, by virtue hereof, be entitled to any rights of a stockholder of the Company and nothing contained in this Warrant shall be construed as conferring upon the Holder the right to vote or to consent or to receive notice as a stockholder in respect of meetings of stockholders for the election of directors of the Company or any other matters or any rights whatsoever as a stockholder of the Company.
 
11.5  Remedies. Each Holder of Warrants and/or Warrant Stock, in addition to being entitled to exercise its rights granted by law, including recovery of damages, shall be entitled to specific performance of its rights provided under this Warrant.

11.6  Successors and Assigns. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the permitted successors and assigns of the Holder hereof, such permitted successors and/or assigns shall be deemed to be a Holder for all purposes hereunder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and to the extent applicable, all Holders of shares of Warrant Stock issued upon the exercise hereof (including transferees), and shall be enforceable by any such Holder.
 
11.7  Amendment. This Warrant and all other Warrants may be modified or amended or the provisions hereof waived only with the written consent of the Company and the Holders. Notwithstanding the foregoing, without a Holder's written consent no such modifica-tion, amendment or waiver shall affect adversely such Holder's rights hereunder in a discrimina-tory manner inconsistent with its adverse effects on rights of other Holders hereunder (other than as reflected by the different number of shares of Warrant Stock held by such Holders). This Warrant cannot be changed, modified, discharged or terminated by oral agreement.
 
11.8  Severability. If any term, provision or restriction of this Warrant is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions and restrictions of this Warrant shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of this Warrant is not affected in any manner materially adverse to either party. Upon such a determination, the parties shall negotiate in good faith to modify this Warrant so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.
