b) Company’s Election to Pay Interest in Kind. Subject to the terms and conditions herein, including, without limitation, the provisions of Sections 3(d) and 4(c) of this Debenture, the decision whether to pay interest hereunder in shares of Common Stock or cash shall be at the discretion of the Company. Prior to the commencement of an Interest Notice Period, the Company shall provide the Holder with written notice of its election to pay interest hereunder on the applicable Interest Payment Date either in cash, shares of Common Stock or a combination thereof (the Company may indicate in such notice that the election contained in such notice shall continue for later periods until revised) and the Interest Share Amount as to the applicable Interest Payment Date. During any Interest Notice Period, the Company’s election (whether specific to an Interest Payment Date or continuous) shall be irrevocable as to such Interest Payment Date. Subject to the aforementioned conditions, failure to timely provide such written

notice shall be deemed an election by the Company to pay the interest on such Interest Payment Date in cash. At any time the Company delivers a notice to the Holder of its election to pay the interest in shares of Common Stock, the Company shall file a prospectus supplement pursuant to Rule 424 disclosing such election. The aggregate number of shares of Common Stock otherwise issuable to the Holder on an Interest Payment Date shall be reduced by the number of Interest Conversion Shares previously issued to the Holder in connection with such Interest Payment Date.

c) Interest Calculations. Interest shall be calculated on the basis of a 365-day year and shall accrue daily commencing on the Original Issue Date until payment in full of the principal sum, together with all accrued and unpaid interest and other amounts which may become due hereunder, has been made. Payment of interest in shares of Common Stock (other than the Interest Conversion Shares issued prior to an Interest Notice Period) shall otherwise occur pursuant to Section 4(d)(ii) and only for purposes of the payment of interest in shares, the Interest Payment Date shall be deemed the Conversion Date. Interest shall cease to accrue with respect to any principal amount converted, provided that the Company in fact delivers the Conversion Shares within the time period required by Section 4(d)(ii). Interest hereunder will be paid to the Person in whose name this Debenture is registered on the records of the Company regarding registration and transfers of this Debenture (the “Debenture Register”). Except as otherwise provided herein, if at any time the Company pays interest partially in cash and partially in shares of Common Stock to the holders of the Debentures, then such payment shall be distributed ratably among the holders of the Debentures based on their (or their predecessor’s initial purchases of Debentures pursuant to the Purchase Agreement.

d) Late Fee. All overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at the rate of 18% per annum (or such lower maximum amount of interest permitted to be charged under applicable law) (“Late Fees”) which will accrue daily, from the date such interest is due hereunder through and including the date of payment. Notwithstanding anything to the contrary contained herein, if on any Interest Payment Date the Company has elected to pay interest in Common Stock and is not able to pay accrued interest in the form of Common Stock because it does not then satisfy the conditions for payment in the form of Common Stock set forth above, then, at the option of the Holder, the Company, in lieu of delivering either shares of Common Stock pursuant to this Section 2 or paying the regularly scheduled cash interest payment, shall deliver, within three Trading Days of each applicable Interest Payment Date, an amount in cash equal to the product of the number of shares of Common Stock otherwise deliverable to the Holder in connection with the payment of interest due on such Interest Payment Date and the highest VWAP during the period commencing on the Interest Payment Date and ending on the Trading Day prior to the date such payment is made. If any Interest Conversion Shares are issued to the Holder in connection with an Interest Payment Date and are not applied against an Interest Share Amount, then the Holder shall promptly return such excess shares to the Company.

e) Prepayment. Except as otherwise set forth in this Debenture, the Company may not prepay any portion of the principal amount of this Debenture without the prior written consent of the Holder.

a) Different Denominations. This Debenture is exchangeable for an equal aggregate principal amount of Debentures of different authorized denominations, as requested by the Holder surrendering the same. No service charge will be made for such registration of transfer or exchange.

b) Investment Representations. This Debenture has been issued subject to certain investment representations of the original Holder set forth in the Purchase Agreement and may be transferred or exchanged only in compliance with the Purchase Agreement and applicable federal and state securities laws and regulations.

c) Reliance on Debenture Register. Prior to due presentment to the Company for transfer of this Debenture, the Company and any agent of the Company may treat the Person in whose name this Debenture is duly registered on the Debenture Register as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Debenture is overdue, and neither the Company nor any such agent shall be affected by notice to the contrary.

d) Market Regulation. Notwithstanding anything herein to the contrary, the Company shall not be obligated to issue any shares of Common Stock pursuant to the provisions of this Debenture if the issuance of such shares of Common Stock would exceed that number of shares of Common Stock which the Company may issue under the Debentures and the Warrants without breaching the Company’s obligations under the rules or regulations of the Trading Market on which the Common Stock is then trading. Such inability to convert shall not otherwise impair the Company’s obligations under this Debenture.

a) Voluntary Conversion. At any time after the Original Issue Date until this Debenture is no longer outstanding, 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(c) hereof). The Holder shall effect conversions by delivering to the Company the form of Notice of Conversion attached hereto as Annex A (a “Notice of Conversion”), specifying therein the principal amount of this Debenture 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 this Debenture to the Company unless the entire

principal amount of this Debenture plus all accrued and unpaid interest thereon has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Debenture in an amount equal to the applicable conversion. 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 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.

b) Conversion Price. The conversion price in effect on any Conversion Date shall be equal to $0.37 (subject to adjustment herein)(the “Conversion Price”).

i. Trading Market Limitations. Notwithstanding anything herein to the contrary, if the Company has not obtained Shareholder Approval (as defined below), then the Company may not issue, upon payment of a Mandatory Default Amount, upon any other provision of the Transaction Documents or upon conversion of this Debenture, a number of shares of Common Stock which, when aggregated with any shares of Common Stock issued prior to such Conversion Date or payment date, as the case may be, (A) pursuant to any Debentures issued pursuant to the Purchase Agreement and (B) pursuant to any Warrants issued pursuant to the Purchase Agreement, would either (i) exceed 19.999% of the number of shares of Common Stock outstanding on the Trading Day immediately preceding the Original Issue Date (such number of shares, the “Issuable Maximum”) or (ii) the issuance to any particular Holder such that the shares owned by such Holder when added to such shares issuable upon such conversion of the Debenture or exercise of the Warrant would result in Holder owning more than 19.999% of the Company’s outstanding shares as of the date of such proposed issuance (“Nasdaq Change in Control Maximum”). Each Holder shall be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing (x) the aggregate principal amount of the Debenture(s) issued and sold to such Holder on the Original Issue Date by (y) the aggregate principal amount of all Debentures issued and sold by the Company on the Original Issue Date; provided that such amount shall not exceed the Nasdaq Change in Control Maximum with respect to any particular Holder. If any Holder shall no longer hold the Debenture(s), then such Holder’s remaining portion of the Issuable Maximum shall be allocated pro-rata among the remaining Holders; provided that such amount shall not exceed the Nasdaq Change in Control Maximum with respect to any particular Holder. If on any Conversion Date: (1) the applicable Conversion Price then in effect is such that the shares issuable under this Debenture on any Conversion Date together with the aggregate number of shares

of Common Stock that would then be issuable upon conversion in full of all then outstanding Debentures and exercise in full of all outstanding Warrants, (2) the issuance to such Holder such that the shares owned by such Holder when added to the shares issuable upon conversion under the Debentures or exercise of the Warrants would result in such Holder owning more than 19.999% of the Company’s shares of Common Stock and (3) the Company’s shareholders shall not have previously approved the transactions contemplated by the Transaction Documents, if any (the “Shareholder Approval”), then the Company shall issue to the Holder requesting a conversion a number of shares of Common Stock equal to such Holder’s pro-rata portion (which shall be calculated pursuant to the terms hereof) of the Issuable Maximum or Nasdaq Change in Control Maximum, as the case may be, and, with respect to the remainder of the aggregate principal amount of the Debentures (including any accrued interest) then held by such Holder for which a conversion in accordance with the applicable conversion price would result in an issuance of shares of Common Stock in excess of such Holder’s pro-rata portion (which shall be calculated pursuant to the terms hereof) of the Issuable Maximum or Nasdaq Change in Control Maximum, as the case may be (the “Excess Principal”), the Company shall be prohibited from converting such Excess Principal, and shall notify the Holder of the reason therefor. This Debenture shall thereafter be unconvertible to such extent until and unless Shareholder Approval is subsequently obtained, but this Debenture shall otherwise remain in full force and effect. Notwithstanding the foregoing, the limitations contained in this Section 4(c)(i) shall not apply at any time, and from time to time, that the Common Stock ceases to be listed on a Trading Market.

ii. Holder’s Restriction on Conversion. The Company shall not effect any conversion of this Debenture, and 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(c)(ii), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the

rules and regulations promulgated thereunder. 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. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(c)(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-Q or Form 10-K, 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 date as of which such number of outstanding shares of Common Stock was reported. The provisions of this Section 4(c) may be waived by the Holder, at the election of the Holder, upon not less than 61 days’ prior notice to the Company, and the provisions of this Section 4(c) shall continue to apply until such 61st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this Section 4(c) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended 4.99% beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such 4.99% limitation. The limitations contained in this paragraph shall apply to a successor holder of this Debenture. The holders of Common Stock of the Company shall be third party beneficiaries of this Section 4(c) and the Company may not waive this Section 4(c) without the consent of holders of a majority of its Common Stock.

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

ii. Delivery of Certificate Upon Conversion. Not later than three Trading Days after any Conversion Date, the Company will deliver or cause to be delivered to the Holder (A) a certificate or certificates representing the Conversion 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 this Debenture (including, if the Company has given notice pursuant to Section 2(b) for payment of interest in shares of Common Stock at least 20 Trading Days prior to the date on which the Conversion Notice is delivered to the Company, shares of Common Stock representing the payment of accrued interest otherwise determined pursuant to Section 2(a) but assuming that the Interest Payment Period is the 20 Trading Days period immediately prior to the date on which the Conversion Notice is delivered to the Company and (B) a bank check in the amount of accrued and unpaid interest (if the Company is required to pay accrued interest in cash). The Company shall, if available and if allowed under applicable securities laws, use its commercially reasonable 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 to the extent permitted by the Depository Trust Company.

iii. Failure to Deliver Certificates. 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 third 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 this Debenture tendered for conversion.

iv. Obligation Absolute; Partial Liquidated Damages. If the Company fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(d)(ii) by the third 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 $1000 of principal amount being converted, $10 per Trading Day (increasing to $20 per Trading Day after 5 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 Conversion 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 Conversion 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 the 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 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 8 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 Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

v. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. 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(d)(ii) by the third Trading Day after the Conversion Date, and if after such third 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 Conversion 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) the 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 (if surrendered) this Debenture in a 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(d)(ii), and thereafter the liquidated damages pursuant to clause (v) above shall cease to accrue. 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 this Debenture with respect to which the actual sale price of the Conversion 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.

vi. Reservation of Shares Issuable Upon Conversion. 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 this Debenture and payment of interest on this Debenture, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder (and the other holders of the Debentures), not less than such number of shares of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 5) upon the conversion of the outstanding principal amount of this Debenture and payment of interest hereunder. 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 Registration Statement is then effective under the Securities Act, registered for public sale in accordance with such Registration Statement.

vii. Fractional Shares. Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the VWAP at such time. If the Company elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

viii. Transfer Taxes. The issuance of certificates for shares of the Common Stock on conversion of this Debenture shall be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of this Debenture so converted and the Company shall not be required to issue or deliver such certificates unless or until

the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

a) Stock Dividends and Stock Splits. If the Company, at any time while this Debenture is outstanding: (A) pays a stock dividend or otherwise makes 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, including as interest thereon), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company in a transaction that is not a Fundamental Transaction, then the Conversion 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 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 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.

b) (A) Subsequent Equity Sales. Subject to Sections 3(d) and 4(c) of this Debenture, if the Company or any Subsidiary thereof, as applicable, at any time while this Debenture is 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 Common Stock Equivalents entitling any Person to acquire shares of Common Stock, at an effective price per share less than the then Conversion Price (such lower price, the “Base Conversion Price” and such issuances collectively, a “Dilutive Issuance”), as adjusted hereunder (if the holder of the Common Stock or Common Stock Equivalents 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 Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made under this Section 5(b) in respect of an Exempt Issuance. The Company shall notify the Holder in writing, no later

than the Business Day following the issuance of any Common Stock or Common Stock Equivalents subject to this section, indicating therein the applicable issuance price, or of applicable reset price, exchange price, conversion price and other pricing terms (such notice the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance, after the date of such Dilutive Issuance the Holder is entitled to receive a number of Conversion Shares based upon the Base Conversion Price regardless of whether the Holder accurately refers to the Base Conversion Price in the Notice of Conversion.

(B) Adjustment for De-listing or Reverse Stock Splits. If at any time while this Debenture is outstanding, the Company either (i) effects a reverse stock split of its Common Stock or (ii) has its securities de-listed from the Nasdaq Capital Market (or any successor entity) (the effective date of such reverse stock split or de-listing, the “Trigger Date”), on the 60^th day following the Trigger Date (the “Reset Date”), the then applicable Conversion Price shall be reset to the lower of (i) the Conversion Price on the Reset Date or (ii) the average of the VWAPs for the 10 Trading Days immediately preceding the Reset Date.

c) Pro Rata Distributions. If the Company, at any time while this Debenture is outstanding, shall distribute to all holders of Common Stock (and not to the holders of the Debenture) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security, then in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

d) Fundamental Transaction. 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 Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of 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 prior 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 Conversion 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 Conversion 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 Transaction 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 (d) and insuring that this Debenture (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

e) Calculations. All calculations under this Section 5 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 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

i. Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any of this Section 5, the Company shall promptly mail to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. If the Company hereafter issues, other than pursuant to the Purchase Agreement, a variable rate security, despite the prohibition thereon in the Purchase Agreement, the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible conversion or exercise price at which such securities may be converted or exercised in the case of a Variable Rate Transaction (as defined in the Purchase Agreement).

ii. Notice to Allow Conversion by Holder. 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 for the purpose of conversion of this Debenture, and shall cause to be mailed to the Holder at its last addresses as it 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. The Holder is entitled to convert this Debenture during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice.

a) Monthly Redemption. On each Monthly Redemption Date, the Company shall redeem the Monthly Redemption Amount plus accrued but unpaid interest, the sum of all liquidated damages and any other amounts then owing to such Holder in respect of this Debenture (the “Monthly Redemption”). The Monthly Redemption Amount due on each Monthly Redemption Date shall be paid in cash; provided, however, as to any Monthly Redemption and upon 20 Trading Days’ prior written irrevocable notice (the “Monthly Redemption Notice” and the 20 Trading Day period immediately following the Monthly Redemption Notice, the “Monthly Redemption Period”), in lieu of a cash redemption payment the Company may elect, subject to Sections 3(d) and 4(c) of this

Debenture, to pay all or part of a Monthly Redemption Amount in Conversion Shares (such dollar amount to be paid on a Monthly Redemption Date in Conversion Shares, the “Monthly Redemption Share Amount”) based on a conversion price equal to the Conversion Price; provided, however, that if the average of the VWAPs for the ten Trading Days 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 10 Trading Day period) (the “Market Price”) is lower than the Conversion Price, in addition to paying such Monthly Redemption Amount through issuing Conversion Shares based on the Conversion Price, the Company shall also pay each Holder an amount in cash equal to the following formula: A minus B multiplied by X, where A = the then applicable Conversion Price, B = the Market Price and X = the Monthly Redemption Amount divided by the then applicable Conversion Price. By way of an example, if the Conversion Price is equal to $0.43 and the Market Price is equal to $0.35 and the Monthly Redemption Amount is equal to $100,000, the Company can either pay $100,000 in cash or can issue 232,558 shares of Common Stock ($100,000/$0.43) and pay $18,605 in cash in satisfaction of such Monthly Redemption Amount ($0.43-$0.35 multiplied by 232,558 shares of Common Stock). The Company may not pay any portion of a Monthly Redemption Amount in Conversion Shares under any circumstances unless, (y) from the date the Holder receives the duly delivered Monthly Redemption Notice through and until the date such Monthly Redemption is paid in full, the Equity Conditions, unless waived in writing by the Holder, have been satisfied. The Company shall deposit an amount of shares equal to the quotient of the applicable Monthly Redemption Share Amount divided by the then Conversion Price (the “Conversion Shares”) to the Holder’s account with the Depository Trust Company on the required payment date. The Holder may convert, pursuant to Section 4(a), 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. Unless otherwise indicated by the Holder in the applicable Notice of Conversion, any principal amount of this Debenture converted during the applicable Monthly Redemption Period until the date the Monthly Redemption Amount is paid in full shall be first applied to the principal amount subject to the Monthly Redemption Amount payable in cash and then to the Monthly Redemption Share Amount. Any principal amount of this Debenture converted during the applicable Monthly Redemption Period in excess of the Monthly Redemption Amount shall be applied against the last principal amount of this Debenture scheduled to be redeemed hereunder, in reverse time order from the Maturity Date; provided, however, if any such conversion is applied to such Monthly Redemption Amount, the Conversion Shares, if any were issued in connection with such Monthly Redemption or were not already applied to such conversions, shall be first applied against such conversion. The Company covenants and agrees that it will honor all Notice of Conversions tendered up until such amounts are paid in full. The Company’s determination to pay a Monthly Redemption in cash, shares of Common Stock or a combination thereof shall be applied ratably to all of the holders of the Debentures based on their (or their predecessor’s) initial purchases of Debentures pursuant to the Purchase Agreement. At any time the Company delivers a notice to the

Holder of its election to pay the Monthly Redemption Amount in shares of Common Stock, the Company shall file a prospectus supplement pursuant to Rule 424 disclosing such election.

b) Redemption Procedure. The payment of cash pursuant to the 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 invalidate ab initio such redemption. Notwithstanding anything to the contrary in this Section 6, the Company’s determination to redeem in cash or its elections under Section 6(b) shall be applied among the Holders of Debentures ratably. The Holder may elect to convert the outstanding principal amount of the Debenture pursuant to Section 4 prior to actual payment in cash for any redemption under this Section 6 by fax delivery of a Notice of Conversion to the Company.

Section 7. Negative Covenants. So long as any portion of this Debenture is outstanding, the Company will not and will not permit any of its Subsidiaries to directly or indirectly:

a) enter into, create, incur, assume or guarantee any indebtedness for borrowed money, including but not limited to, drawing down any amounts under its credit agreement with Bridge Bank, N.A. or a guarantee, on or with respect to any of its property or assets (“Indebtedness”), other than Permitted Indebtedness;

c) amend its certificate of incorporation, bylaws or other charter documents so as to materially and adversely affect any rights of the Holder; provided that the provisions of this Section 7(c) will not apply to any modifications of the certificate of incorporation, bylaws or charter done in connection with any reverse stock split or as a result of any delisting of the Company’s Common Stock from the Nasdaq Capital Market;

i. any default in the payment of (A) the principal amount of any Debenture, or (B) interest (including Late Fees) on, or liquidated damages in respect of, any Debenture, as and when the same shall become due and payable (whether on a Conversion Date or the Maturity Date or by acceleration or otherwise) which default, solely in the case of an interest payment (including Late Fees) or liquidated damages or other default under clause (B) above, is not cured, within 3 Trading Days;

iii. a default or event of default (subject to any grace or cure period provided for in the applicable agreement, document or instrument) shall occur under any of the Transaction Documents within the earlier to occur of (A) 5 Trading Days after notice of such default sent by the Holder or by any other Holder and (B) 10 Trading Days after the Company shall become or should have been aware of such failure;

iv. any representation or warranty made herein, in any other Transaction Documents shall be untrue or incorrect in any material respect as of the date when made or deemed made;

vi. the Company or any Subsidiary shall default in any of its obligations under any mortgage, credit agreement or other facility, indenture agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured or evidenced any indebtedness for borrowed money or money due under any long term leasing or factoring arrangement of the Company in an amount exceeding $150,000, whether such indebtedness now exists or shall hereafter be created and such default shall result in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable;

viii. a Registration Statement shall not have been declared effective by the Commission on or prior to the 150^th calendar day after the Closing Date;

ix. if, during the Effectiveness Period (as defined in the Registration Rights Agreement), the effectiveness of the Registration Statement lapses for any

reason or the Holder shall not be permitted to resell Registrable Securities (as defined in the Registration Rights Agreement) under the Registration Statement, in either case, for more than 20 consecutive Trading Days or 30 non-consecutive Trading Days during any 12 month period; provided, however, that in the event that the Company is negotiating a merger, consolidation, acquisition or sale of all or substantially all of its assets or a similar transaction and in the written opinion of counsel to the Company, the Registration Statement, would be required to be amended to include information concerning such transactions or the parties thereto that is not available or may not be publicly disclosed at the time, the Company shall be permitted an additional 10 consecutive Trading Days during any 12 month period relating to such an event;

x. the Company shall fail for any reason to deliver certificates to a Holder prior to the third Trading Day after a Conversion Date pursuant to and in accordance with Section 4(d) or the Company shall provide notice to the Holder at any time, of its intention not to comply with requests for conversions of any Debentures in accordance with the terms hereof;

xi. any Person shall breach the voting agreements delivered to the initial Holders pursuant to Section 2.2(a) of the Purchase Agreement and the Company does not obtain Shareholder Approval; or

xii. the Company shall draw any amount whatsoever on its credit agreement with Bridge Bank, N.A. without the express prior written consent of Holder.

b) Remedies Upon Event of Default. If any Event of Default occurs, the full principal amount of this Debenture, together with interest and other amounts owing in respect thereof, to the date of acceleration shall become, at the Holder’s election, immediately due and payable in cash. The aggregate amount payable upon an Event of Default shall be equal to the Mandatory Default Amount. Commencing 5 days after the occurrence of any Event of Default that results in the eventual acceleration of this Debenture, the interest rate on this Debenture shall accrue at the rate of 18% per annum, or such lower maximum amount of interest permitted to be charged under applicable law. Upon the payment in full of the Mandatory Default Amount on this entire Debenture the Holder shall promptly surrender this Debenture to or as directed by the Company. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights as a Debenture holder until such time, if any, as the full payment under this Section shall have been received by it. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

a) Notices. Any and all notices or other communications or deliveries to be provided by the Holder hereunder, including, without limitation, any Notice of Conversion, shall be in writing and delivered personally, by facsimile, sent by a nationally recognized overnight courier service, addressed to the Company, at the address set forth above, facsimile number (408)-750-6842, Attn: Chief Financial Officer or such other address or facsimile number as the Company may specify for such purposes by notice to the Holder delivered in accordance with this Section.

b) Absolute Obligation. Except as expressly provided herein, no provision of this Debenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, interest and liquidated damages (if any) on, this Debenture at the time, place, and rate, and in the coin or currency, herein prescribed. This Debenture is a direct debt obligation of the Company. This Debenture ranks pari passu with all other Debentures now or hereafter issued under the terms set forth herein.

c) Lost or Mutilated Debenture. If this Debenture shall be mutilated, lost, stolen or destroyed, the Company shall execute and deliver, in exchange and substitution for and upon cancellation of a mutilated Debenture, or in lieu of or in substitution for a lost, stolen or destroyed Debenture, a new Debenture for the principal amount of this Debenture so mutilated, lost, stolen or destroyed but only upon receipt of evidence of such loss, theft or destruction of such Debenture, and of the ownership hereof, and indemnity, if requested, all reasonably satisfactory to the Company.

d) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Debenture shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to

the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, or such New York Courts are improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Debenture and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Debenture or the transactions contemplated hereby. If either party shall commence an action or proceeding to enforce any provisions of this Debenture, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorneys fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

e) Waiver. Any waiver by the Company or the Holder of a breach of any provision of this Debenture shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture. The failure of the Company or the Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Debenture. Any waiver must be in writing.

f) Severability. If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of

or interest on this Debenture as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

g) Next Business Day. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.
