1.             Definitions .  In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement or the Company’s Certificate of Designations of the Series A-1 Senior Preferred Stock (the “ Certificate of Designations ”), as applicable.

2.             Registration of Warrant .  The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “ Warrant Register ”), in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

3.             Registration of Transfers .  This Warrant and all rights hereunder are transferable in whole or in part upon the books of the Company by the Holder hereof; provided, however, that the transferee shall agree in writing to be bound by the terms and subject to the conditions of this Warrant and the Purchase Agreement.  The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at its address specified herein.  Upon any such registration or transfer, a new warrant to purchase Common Stock, in substantially the form of this Warrant (any such new warrant, a “ New Warrant ”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder.  The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

4.             Exercise and Duration of Warrants .

(a)           Subject to the limitations set forth in Section 12 hereof, this Warrant shall be exercisable, prior to the Amendment Date with respect to the Holder’s pro rata portion of all Available Underlying Shares (based on the proportion of Warrant Shares to the total Available Underlying Shares), and from and after the Amendment Date with respect to all Warrant Shares, by the registered Holder at any time and from time to time on or after the date hereof to and including the Expiration Date.  At 6:30 P.M., New York City time on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value; provided that, if the average of the Closing Prices for the five (5) Trading Days immediately prior to (but not including) the Expiration Date exceeds the Exercise Price on the Expiration Date, then this Warrant shall be deemed to have been exercised in full (to the extent not previously exercised, and subject to the limitations set forth in Section 12 hereof) on a “cashless exercise” basis at 6:30 P.M. New York City time on the Expiration Date.

(b)           A Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached hereto (the “ Exercise Notice ”), appropriately completed and duly signed, and (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise Notice and if a “cashless exercise” may occur at such time pursuant to Section 10 below), and the date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “ Exercise Date .”  The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder.  Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.  The Holder shall deliver the original Warrant to the Company within 30 days after the full exercise of this Warrant; provided that the Holder’s failure to so deliver the original Warrant shall not affect the validity of such exercise or any of the Company’s obligations under this Warrant and the Company’s sole remedy for the Holder’s failure to deliver the original Warrant shall be to obtain an affidavit of lost warrant from the Holder.

(c)           If upon the date that is seven (7) years from the original date of issuance of this Warrant, any portion of this Warrant remains unexercised, then the Company shall issue to the Holder a new Warrant to purchase Common Stock, in substantially the form of this Warrant, with a new Maturity Date of seven (7) years from the original Maturity Date and with a new Exercise Price equal to the Closing Price on the original Maturity Date and exercisable for the number of Warrant Shares equal to quotient of (A) the greater of the Black-Scholes value of the remaining unexercised portion of this Warrant (without regard to any limitations on the exercise hereof) (x) on the original date of issuance of this Warrant, and (y) on the original Maturity Date, in each case as determined in accordance with Annex A attached to the Purchase Agreement, divided by (B) the new Exercise Price as determined above.  Notwithstanding the foregoing, this Section 4(c) shall cease to apply in the event that prior to the original Maturity Date, the Company satisfies Section 4.22 of the Purchase Agreement.

5.             Delivery of Warrant Shares .

(a)           Subject to Sections 4(a) and 5(c) below and the limitations set forth in Section 12 , upon exercise of this Warrant, the Company shall promptly (but in no event later than three (3) Trading Days after the Exercise Date) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the Warrant Shares issuable upon such exercise, free of restrictive legends unless a registration statement covering the resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective and the Warrant Shares are not freely transferable without volume restrictions pursuant to Rule 144 under the Securities Act.  The Holder, or any Person so designated by the Holder to receive Warrant Shares, shall be deemed to have become holder of record of such Warrant Shares as of the Exercise Date.  The Company shall, upon request of the Holder, use its reasonable best efforts to deliver Warrant Shares hereunder electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions.

(b)           Subject to Sections 4(a) and 5(c) below and the limitations set forth in Section 12 hereof, this Warrant is exercisable, either in its entirety or, from time to time, for all or a portion of the number of Warrant Shares.  Upon surrender of this Warrant following one or more partial exercises, the Company shall issue or cause to be issued, at its expense, a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

(c)           In addition to any other rights available to a Holder, if the Company fails to deliver or cause to be delivered to the Holder a certificate representing Warrant Shares by the third (3 ^rd )Trading Day after the date on which delivery of such certificate is required by this Warrant, and if after such third (3 ^rd )Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares that the Holder anticipated receiving from the Company (a “ Buy-In ”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “ Buy-In Price ”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Price on the date of the event giving rise to the Company’s obligation to deliver such certificate.

(d)           The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions hereof are absolute and unconditional (provided that prior to the Amendment Date, such obligations extend to the Holder’s pro rata portion of all Available Underlying Shares, and from and after the Amendment Date such obligations extend to all Warrant Shares), irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares (other than such limitations contemplated by this Warrant).  Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

(e)           Each certificate for Warrant Shares shall bear a restrictive legend to the extent and as provided in the Purchase Agreement and any certificate issued at any time in exchange or substitution for any certificate bearing such legend shall also bear such legend, unless, in the opinion of counsel for the Holder thereof (which opinion shall be reasonably satisfactory to counsel for the Company), the securities represented thereby are not, at such time, required by law to bear such legend.

6.            Charges, Taxes and Expenses .  Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any withholding or other tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof.  The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7.            Replacement of Warrant .  If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested.  Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe.

8.             Reservation of Warrant Shares .  The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, prior to the Amendment Date, a number of shares of Common Stock equal to the Holder’s pro rata portion of all Available Underlying Shares, and from and after the Amendment Date, a number of shares of Common Stock equal to all Warrant Shares, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9 ).  The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.  The Company will take all such action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Stock may be listed.

9.             Certain Adjustments .  The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9 .

(a)            Stock Dividends and Splits .  If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event.  Any adjustment made pursuant to clause (i) of this paragraph 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 clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(b)            Pro Rata Distributions .  If the Company, at any time while this Warrant is outstanding, distributes to holders of Common Stock (and not to all Holders of Warrants in respect of their ownership thereof) (i) evidences of its Indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) cash or any other asset (in each case, “ Distributed Property ”), then in each such case the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution shall be adjusted (effective on such record date) to equal the product of such Exercise Price times a fraction of which the denominator shall be the average of the Closing Prices for the five (5) Trading Days immediately prior to (but not including) such record date and of which the numerator shall be such average less the then fair market value of the Distributed Property distributed in respect of one (1) outstanding share of Common Stock, as determined by the Company’s independent certified public accountants that regularly examine the financial statements of the Company (an “ Appraiser ”).  In such event, the Holder, after receipt of the determination by the Appraiser, shall have the right to select an additional appraiser (which shall be a nationally recognized accounting firm), in which case such fair market value shall be deemed to equal the average of the values determined by each of the Appraiser and such appraiser.  As an alternative to the foregoing adjustment to the Exercise Price, at the request of the Holder delivered before the 90 ^th day after such record date, the Company will deliver to such Holder, within five (5) Trading Days after such request (or, if later, on the effective date of such distribution), the Distributed Property that such Holder would have been entitled to receive in respect of the Warrant Shares for which this Warrant could have been exercised immediately prior to such record date.  If such Distributed Property is not delivered to a Holder pursuant to the preceding sentence, then upon expiration of or any exercise of the Warrant that occurs after such record date, such Holder shall remain entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise (if applicable), such Distributed Property.

(c)            Fundamental Transactions .  If, at any time while this Warrant is outstanding, any of the following occur in one or a series of related transactions: (i) an acquisition after the Closing Date by an individual or legal entity or “group” (as described in Rule 13d-5(b)(1)
