Section 4Conversion.

(a) (i) At any time after the Closing Date, this Debenture shall be convertible into shares of Common Stock at the option of the Holder, in whole or in part at any time and from time to time (subject to the limitations on conversion set forth in Section 4(a)(ii) hereof). The Holder shall effect conversions by delivering to the Company the form of Notice of Conversion attached hereto asAnnex A (a "Notice of Conversion"), specifying therein the principal amount of Debentures to be converted and the date on which such conversion is to be effected (a "Conversion Date"). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is provided hereunder. To effect conversions hereunder, the Holder shall not be required to physically surrender Debentures to the Company unless the entire principal amount of this Debenture has been so converted. Conversions hereunder shall have the effect of lowerin g the outstanding principal amount of this Debenture. The Holder and the Company shall maintain records showing the principal amount converted and the date of such conversions. The Company shall deliver any objection to any Notice of Conversion within one (1) Business Day of receipt of such notice. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Debenture, the unpaid and unconverted principal amount of this Debenture may be less than the amount stated on the face hereof. In the event a Holder of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse conversion based on any claim that the Holder or any one associated or affiliated with the Holder has been engaged in any violat ion of law, agreement or for any other reason, unless an injunction from a court, on notice, restraining and/or enjoining conversion of all or part of this Debenture shall have been sought and obtained and the Company posts a surety bond for the benefit of the Holder in the amount of 150% of the principal amount of this Debenture outstanding, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of an injunction precluding the same, the Company shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 3 herein for the Company's failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without

limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holders from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(ii)Beneficial Ownership Restrictions. The Holder shall not have the right to convert any portion of this Debenture, pursuant to Section 4(a) or otherwise, to the extent that after giving effect to such conversion, the Holder (together with the Holder's affiliates), as set forth on the applicable Notice of Conversion, would beneficially own in excess of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of this Debenture with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Debenture beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Debentures or the Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 4(a)(ii), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. To the extent that the limitation contained in this section applies, the determination of whether this Debenture is convertible (in relation to other securities owned by the Holder) and of which a portion of this Debenture is convertible shall be in the sole discretion of such Holder. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section 4(a)(ii), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company's most recent Form 10-QSB or Form 10-KSB, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company's Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Debenture, by the Holder or its affiliates since the d ate as of which such number of outstanding shares of Common Stock was reported. The provisions of this Section 4(a)(ii) may be waived by the

Holder upon, at the election of the Holder, not less than 61 days' prior notice to the Company, and the provisions of this Section 4(a)(ii)(B) shall continue to apply until such 61^st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver).

(iii)Underlying Shares Issuable Upon Conversion. The number of shares of Common Stock issuable upon a conversion shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Debenture to be converted and (y) the Set Price.

(b) (i) Not later than five (5) Trading Days after any Conversion Date, the Company will deliver to the Holder a certificate or certificates for the Underlying Shares which shall be free of restrictive legends and trading restrictions (other than those required by the Purchase Agreement) representing the number of shares of Common Stock being acquired upon the conversion of Debentures. The Company shall, upon request of the Holder, if available and if allowed under applicable securities laws, use its best efforts to deliver any certificate or certificates required to be delivered by the Company under this Section electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions. If in the case of any Notice of Conversion such certificate or certificates are not delivered to or as directed by the applicable Holder by the fifth (5^th) Trading Day after a Conversion Date, the Holder shall be entitled by written notice to the Company at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Company shall immediately return the certificates representing the principal amount of Debentures tendered for conversion.

(ii) If the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(b)(i) by the fifth (5^th) Trading Day after the Conversion Date, the Company shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of principal amount being converted, $50 per Trading Day (increasing to $100 per Trading Day after five (5) Trading Days and increasing to $200 per Trading Day ten (10) Trading Days after such damages begin to accrue) for each Trading Day after such third Trading Day until such certificates are delivered. The Company's obligations to issue and deliver the Underlying Shares upon conversion of this Debenture in accordance with the terms hereof are absolute and unconditional, 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 such Underlying Shares;provided,however, such delivery shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event a Holder of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse conversion based on any claim that the Holder or any one associated or affiliated with the Holder of has been engaged in any violation of law, agreement or for any other reason, unless, an injunction from a court, on notice, restraining and or enjoining conversion of all or part of this Debenture shall have been sought and obtained and the Company posts a surety bond for the benefit of the Holder in the amount of 150% of the principal amount of this Debenture outstanding, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of an injunction precluding the same, the Company shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 3 herein for the Company's failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holders from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(iii) In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(b)(i) by the fifth (5^th) Trading Day after the Conversion Date, and if after such fifth (5^th) Trading Day the Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by such Holder of the Underlying Shares which the Holder anticipated receiving upon such conversion (a "Buy-In"), then the Company shall (A) pay in cash to the Holder (in addition to any remedies available to or elected by the Holder) the amount by which (x) the Holder's total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder anticipated receiving from the conversion at issue multiplied by (2) th e actual sale price of the Common Stock at the time of the sale (including brokerage commissions, if any) giving rise to such purchase obligation and (B) at the option of the Holder, either reissue Debentures in principal amount equal to the principal amount of the attempted conversion or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its delivery requirements under Section 4(b)(i). For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of

Debentures with respect to which the actual sale price of the Underlying Shares at the time of the sale (including brokerage commissions, if any) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In. Notwithstanding anything contained herein to the contrary, if a Holder requires the Company to make payment in respect of a Buy-In for the failure to timely deliver certificates hereunder and the Company timely pays in full such payment, the Company shall not be required to pay such Holder liquidated damages under Section 4(b)(ii) in respect of the certificates resulting in such Buy-In.

(c) (i) The conversion price in effect on any Conversion Date shall be equal to$0.22(subject to adjustment herein)(the "Set Price").

(ii) If the Company, at any time while the Debentures are outstanding: (A) shall pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company pursuant to this Debenture), (B) subdivide outstanding shares of Common Stock into a larger number of shares, (C) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issue by reclassification of shares of the Common Stock any shares of capital stock of the Company, then the Set Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock outstanding after such event. An y adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(iii) If the Company, at any time while Debentures are outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of Common Stock or Common Stock Equivalents at a price per share less than the Closing Price at the record date mentioned below, then the Set Price shall be adjusted by multiplying the Set Price in effect immediately prior to such record date by a fraction, of which the denominator shall be the number of shares of the Common Stock (excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock (excluding

treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at the Closing Price on the record date. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants.

(iv) If the Company or any subsidiary thereof, as applicable, at any time while Debentures are outstanding, shall offer, sell, grant any option to purchase or offer, sell or grant any right to reprice its securities, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or any equity or equity equivalent securities (including any equity, debt or other instrument that is at any time over the life thereof convertible into or exchangeable for Common Stock) (collectively, "Common Stock Equivalents") entitling any Person to acquire shares of Common Stock, at an effective price per share less than the Set Price (if the holder of the Common Stock or Common Stock Equivalent so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which is issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share which is less than the Set Price, such issuance shall be deemed to have occurred for less than the Set Price), then, the Set Price shall be adjusted for such conversions as Holders shall indicate in its Notice of Conversions to equal the effective conversion, exchange or purchase price for such Common Stock or Common Stock Equivalents (including any reset provisions thereof) at issue. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. The Company shall notify the Holder in writing, no later than the business day following the issuance of any Common Stock or Common Stock Equivalent subject to this section, indicating therein the applicable issuance price, or of applicable reset price, exchange price, conversion price and other pricing terms.

(v) In case of any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property, the Holders shall have the right thereafter to, at their option, (A) convert the then outstanding principal amount and any other amounts then owing hereunder in respect of this Debenture only into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of the Common Stock following such reclassification or share exchange, and the Holders of the Debentures shall be entitled upon such event to receive such amount of securities, cash or property as the shares of the Common Stock of the Company into which the then outstanding principal amount and any other amounts then owing hereunder in respect of this Debenture could have been converted immediately prior to such reclassification or share exchange would have been entitled or (B) require the

Company to prepay the aggregate of its outstanding principal amount of Debentures, plus other amounts due and payable thereon, at a price determined in accordance with Section 3(b). The entire prepayment price shall be paid in cash. This provision shall similarly apply to successive reclassifications or share exchanges.

(vi) All calculations under this Section 4 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 4, the number of shares of Common Stock deemed to be outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) outstanding.

(vii) If (A) the Company shall declare a dividend (or any other distribution) on the Common Stock; (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock; (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights; (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company; then, in each case, the Company shall cause to be filed at each office or agency maintained fo r the purpose of conversion of the Debentures, and shall cause to be mailed to the Holders at their last addresses as they shall appear upon the stock books of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange;provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. Holders are entitled to convert Debentures during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice.

(viii) If, at any time while this Debenture is outstanding, (A) the Company effects any merger or consolidation of the Company with or into another Person, (B) the

Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a "Fundamental Transaction"), then upon any subsequent conversion of this Debenture, the Holder shall have the right to receive, for each Underlying Share that would have been issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately p rior to such Fundamental Transaction, the holder of one share of Common Stock (the "Alternate Consideration"). For purposes of any such conversion, the determination of the Set Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Set Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Debenture following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Tr ansaction shall issue to the Holder a new Debenture consistent with the foregoing provisions and evidencing the Holder's right to convert such Debenture into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that this Debenture (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. In the event a Change of Control Transaction, including any Fundamental Transaction constituting a Change of Control Transaction, the Holder may request, before the 90th day after such Change of Control Transaction, that the Company (or any such successor or surviving entity) will purchase the Debenture from the Holder for a purchase price, payable in cash within five Trading Days after such request (or, if later, on the effective date of the Fundamental Transactio n), equal to the Mandatory Prepayment Amount on the date of such request.

(ix) Notwithstanding the foregoing, no adjustment will be made under this paragraph (c) in respect of (A) the granting of options to employees, officers and directors of the Company pursuant to any stock option plan duly adopted by a

majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, (B) upon the exercise of this Debenture or any other Debenture of this series or of any other series or security issued by the Company in connection with the offer and sale of this Company's securities pursuant to the Purchase Agreement, or (C) upon the exercise of or conversion of any Convertible Securities, options or warrants issued and outstanding on the Original Issue Date, provided such securities have not been amended since the date of the Purchase Agreement, or (D) acquisitions or strategic investments, the primary purpose of which is not to raise capital.

(c) The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of the Debentures, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holders, not less than such number of shares of the Common Stock as shall (subject to any additional requirements of the Company as to reservation of such shares set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 4(b)) upon the conversion of the outstanding principal amount of the Debentures. The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid, nonassessable and, if the Underlying Shares Registration Statement has been declared effective under the Securities Act, registered for public sale in accord ance with such Underlying Shares Registration Statement.

Section 5.Redemption.

(a)Monthly Redemption. On each Monthly Redemption Date, the Company shall redeem the Holder's Pro-Rata Portion of the Monthly Redemption Amount plus the sum of all liquidated damages and any other amounts then owing to such Holder in respect of any Debentures held by such Holder. "Pro Rata Portion" is the lower of (i) the product of the Monthly Redemption Amount multiplied by ratio of (A) the principal amount of this Debenture held by the original Holder on the Original Issue Date and (B) the sum of the aggregate original principal amounts of the Debentures issued to all Holders on the Original Issue Date, or (ii) the aggregate principal amounts of the Debentures outstanding and held by such Holder at the Redemption Date. If the Holder assigns any portion of this Debenture to multiple assignees, in connection with such assignments, the Holder shall instruct the Company as to how to apportion the original principal amount in (x) above among such assignees for purposes of calculating the Pro-Rata Portions of the assignees. If a Holder and its transferees no longer hold any Debentures, then the Pro Rata Portion shall be recalculated to exclude the original principal amount of any Debentures once held by such Holder and its transferees, if any, from clause (y) above. The Monthly Redemption Amount due on each Monthly Redemption Date shall, except as provided in this Section, be paid in cash. As to any Monthly Redemption and upon 20 Trading Days' prior written irrevocable notice, in lieu of a cash redemption payment the Company may elect to pay all or a portion of a Monthly Redemption in Underlying Shares based on a conversion price equal to the lesser of (i) the then Set Price and (ii) 85% of the average of the 20 Closing Prices immediately prior to the

applicable Monthly Redemption Date (subject to adjustment for any stock dividend, stock split, stock combination or other similar event affecting the Common Stock during such 20 Trading Day period)(the "Monthly Conversion Price");provided,however, that the Company may not pay the Monthly Redemption Amount in Underlying Shares unless, (i) during the 20 Trading Day prior notice period immediately prior to the applicable Monthly Redemption Date until the Monthly Redemption has occurred each of the Equity Conditions shall have been met and (ii) on or prior to the 20^th Trading Day prior to such Monthly Redemption Date, the Company irrevocably notifies the Holder that it will issue Underlying Shares in lieu of cash and in such notice the Company shall have indicated the amount to be paid in Underlying Shares (the Company may indicate in such notice that the election contained in such notice shall continue for later periods until revised or until the Equi ty Conditions are no longer satisfied). The Holder may convert, pursuant to Section 4, any principal amount of this Debenture subject to a Monthly Redemption at any time prior to the date that the Monthly Redemption Amount and all amounts owing thereon are due and paid in full. The Company covenants and agrees that it will honor all Conversion Notices tendered up until such amounts are paid in full. If the Holder elects to convert any principal amount of this Debenture subject to a Monthly Redemption prior to the Monthly Redemption Date, such Holder's Monthly Redemption Amount paid on such Monthly Redemption Date shall be reduced by the principal amount so converted. For clarity, such conversion shall not reduce the Mandatory Redemption Amount payable on any future Mandatory Redemption Date.

(b)Redemption Procedure. The payment of cash and/or issuance of Common Stock, as the case may be, pursuant to a Monthly Redemption shall be made on the Monthly Redemption Date. If any portion of the cash payment for a Monthly Redemption shall not be paid by the Company by the respective due date, interest shall accrue thereon at the rate of 18% per annum (or the maximum rate permitted by applicable law, whichever is less) until the payment of the Monthly Redemption Amount plus all amounts owing thereon is paid in full. Alternatively, if any portion of the Monthly Redemption Amount remains unpaid after such date, the Holders subject to such redemption may elect, by written notice to the Company given at any time thereafter, to invalidateab initio such redemption. Notwithstanding anything to the contrary in this Section 5, the Company's determination to redeem in cash or shares of Common Stock shall be applied among the Holders of Debentures according to each Holder's Pro-Rata Portion.
