7% CONVERTIBLE DEBENTURE

DUE March 27, 2005

THIS DEBENTURE is one of a series of duly authorized and issued Debentures of Path 1 Network Technologies, Inc., a Delaware corporation, having a principal place of business at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (the “Company”), designated as its 7% Convertible Debenture due 24 months from their date of issuance (the “Debentures”).

FOR VALUE RECEIVED, the Company promises to pay to HPC Capital Management or its registered assigns (the “Holder”), the principal sum of $10,000 on March 27, 2005 or such earlier date as the Debentures are required or permitted to be repaid as provided hereunder (the “Maturity Date”) and to pay interest to the Holder on the aggregate unconverted and then outstanding principal amount of this Debenture at the rate of 7% per annum, payable semi-annually on June 1, and December 1, beginning on the first such date after the Original Issue Date and on each Conversion Date (as to that principal amount then being converted), on each Monthly Redemption Date (as to that principal amount then being redeemed) and on the Maturity Date (except that, if any such date is not a Business Day, then such payment shall be due on the next succeeding Business Day) (each such date, an “Interest Payment Date”), in cash or shares of Common Stock at the Interest Conversion Rate, or a combination thereof; provided, however, payment in shares of Common Stock may only occur if: (i) there is an effective Underlying Shares Registration Statement pursuant to which the Holder is permitted to utilize the prospectus thereunder to resell all of the shares of

Common Stock to be issued in lieu of cash (and the Company believes, in good faith, that such effectiveness will continue uninterrupted for the foreseeable future), (ii) the Common Stock is listed for trading on a Principal Market (and the Company believes, in good faith, that trading of the Common Stock on a Principal Market will continue uninterrupted for the foreseeable future), (iii) there is a sufficient number of authorized but unissued and otherwise unreserved shares of Common Stock for the issuance of all of the share issuable pursuant to the Transaction Documents, including the shares to be issued for interest in lieu of cash and (iv) such issuance would be permitted in full without violating the limitations set forth in Section 4(a)(ii). Subject to the terms and conditions herein, the decision whether to pay interest hereunder in shares of Common Stock or cash shall be at the discretion of the Company. Not less than 20 Trading Days prior to each Interest Payment Date, the Company shall provide the Holder with irrevocable written notice of its election to pay interest hereunder either in cash or shares of Common Stock (the Company may indicate in such notice that the election contained in such notice shall continue for later periods until revised upon 20 days’ prior written notice). 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. Interest shall be calculated on the basis of a 360-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 shall otherwise occur pursuant to Section 4(b) and for purposes of the payment of interest in shares only, 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 Underlying Shares within the time period required by Section 4(b)(i). 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 Debentures (the “Debenture Register”). Except as otherwise provided herein, if at anytime the Company pays interest partially in cash and partially in shares of Common Stock, then such payment shall be distributed ratably among the Holders based upon the principal amount of Debentures held by each Holder. 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 Fee”) which will accrue daily, from the date such interest is due hereunder through and including the date of payment. The Company may not prepay any portion of the principal amount on this Debenture without the prior written consent of the Holder.

This Debenture is subject to the following additional provisions:

Section 1. 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.

Section 2. 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. 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.

Section 3. Events of Default.

(ii) the Company shall fail to observe or perform any other covenant, agreement or warranty contained in, or otherwise commit any breach of any of the Transaction Documents (other than a breach by the Company of its obligations to deliver shares of Common Stock to the Holder upon conversion or interest payment which breach is addressed in clause (x) below) which is not cured, if possible to cure, within 5 days of notice of such default sent by the Holder (except with respect to breaches pursuant to Sections 4.1, 4.8 and 4.9 of the Purchase Agreement and Section 3(a) of the Warrant);

(iii) the Company or any of its subsidiaries shall commence, or there shall be commenced against the Company or any such subsidiary a case under any applicable bankruptcy or insolvency laws as now or hereafter in effect or any successor thereto, or the Company commences any other proceeding under any reorganization, arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or similar law of any jurisdiction whether now or hereafter in effect relating to the Company or any subsidiary thereof or there is commenced against the Company or any subsidiary thereof any such bankruptcy, insolvency or other proceeding which remains undismissed for a period of 60 days; or the Company or any subsidiary thereof is adjudicated insolvent or bankrupt; or any order of relief or other order approving any such case or proceeding is entered; or the Company or any subsidiary thereof suffers any appointment of any custodian or the like for it or any substantial part of its property which continues undischarged or unstayed for a period of 60 days; or the Company or any subsidiary thereof makes a general

(vii) an Underlying Shares Registration Statement shall not have been declared effective by the Commission on or prior to the 180th calendar day after the Original Issue Date;

(viii) if, during the Effectiveness Period (as defined in the Registration Rights Agreement), the effectiveness of the Underlying Shares 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 Underlying Shares Registration Statement, in either case, for more than 10 consecutive Trading Days or 20 non-consecutive Trading Days during any 12 month period;

(ix) an Event (as defined in the Registration Rights Agreement) shall not have been cured to the satisfaction of the Holder prior to the expiration of thirty days from the Event Date (as defined in the Registration Rights Agreement) relating thereto (other than an Event resulting from a failure of an Underlying Shares Registration Statement to be declared effective by the Commission on or prior to the Effectiveness Date (as defined in the Registration Rights Agreement), which shall be covered by Section 3(a)(vii));

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

(xi) the Company shall fail for any reason to deliver the payment in cash pursuant to a Buy-In (as defined herein) within five days after notice thereof is delivered hereunder.

All Debentures for which the full prepayment price hereunder shall have been paid in accordance herewith shall promptly be surrendered 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 ▇▇▇▇▇▇ 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.

Section 4. Conversion.

(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 conversion notice attached hereto as Annex A (a “Conversion Notice”), specifying therein the principal amount of Debentures to be converted and the date on which such conversion is to be effected (a “Conversion Date”) and shall contain a completed schedule in the form of Schedule 1 to the Conversion Notice (as amended on each Conversion Date, the “Conversion Schedule”) reflecting the remaining principal amount of this Debenture and all accrued and unpaid interest thereon subsequent to the conversion at issue. If no Conversion Date is specified in a Conversion Notice, the Conversion Date shall be the date that such Conversion Notice 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 lowering the outstanding principal amount of this Debenture plus all accrued and unpaid interest thereon in an amount equal to the applicable conversion, which shall be evidenced by entries set forth in the Conversion Schedule. 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 the figures represented in the Conversion Schedules 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. 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 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) Certain Conversion Restrictions. A Holder may not convert Debentures or receive shares of Common Stock as payment of interest hereunder to the extent such conversion or receipt of such interest payment would result in the Holder, together with its Affiliates, beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.999% of the then issued and outstanding shares of Common Stock, including shares issuable upon conversion of, and payment of interest on, the Debentures held by such Holder after application of this Section. The Holder shall be entitled to rely on the Company’s public filing with respect to the number of shares of Common Stock which are then issued and outstanding, and the Holder may inquire of the Company’s Chief Financial Officer to obtain a more current number, which shall be provided within 2 Business Days of written request therefor. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a Conversion Notice that such Conversion Notice has not violated the restrictions set forth in this paragraph. If the Holder has delivered a Conversion Notice for a principal amount of Debentures that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Company shall notify the Holder of this fact and shall honor the conversion for the maximum principal amount permitted to be converted on such Conversion Date in accordance with the periods described in Section 4(b) and, at the option of the Holder, either retain any principal amount tendered for conversion in excess of the permitted amount hereunder for future conversions or return such excess principal amount to the Holder. In the event of a merger or consolidation of the Company with or into another Person, this paragraph shall not apply with respect to a determination of the number of shares of common stock issuable upon conversion in full of the Debentures if such determination is necessary to establish the Securities or other assets which the holder of Common Stock shall be entitled to receive upon the effectiveness of such merger or consolidation. The provisions of this Section 4(a)(ii) 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(a)(ii) 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). No conversion of this Debenture in violation of this Section 4(a)(ii) but otherwise in accordance with this Debenture shall affect the status of the Underlying Shares as validly issued, fully-paid and nonassessable.

(iii) Underlying Shares Issuable Upon Conversion and Pursuant to Interest.

(A) Conversion of Principal Amount. 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, and

(B) Payment of Interest in Underlying Shares. The number of shares of Common Stock issuable upon payment of interest under this Debenture shall be the number determined by (x) the product of (I) the outstanding principal amount of this Debenture to be converted and (II) the product of (aa) the quotient obtained by dividing 7% by 360 and (bb) the number of days for which such principal amount was outstanding, divided by (y) the applicable Interest Conversion Rate, provided, that if the Company shall have elected to pay the interest due on an Interest Payment Date in cash pursuant to the terms hereof, this subsection (B) shall not be used in the calculation of the number of shares of Common Stock issuable upon a conversion hereunder.

(1) the number of shares of Common Stock at the time authorized, unissued and unreserved for all purposes, or held as treasury stock, is insufficient to honor such conversion;

(2) the Common Stock shall fail to be listed or quoted for trading on a Principal Market; or

(3) the Company has failed to timely satisfy its conversion obligations hereunder.

then, at the option of the Holder, the Company, in lieu of delivering shares of Common Stock pursuant to this Section 4, shall deliver, within three Trading Days of each applicable Conversion 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 such Conversion Date and the highest VWAP during the period commencing on the Conversion Date and ending on the Trading Day prior to the date such payment is made.

(b) (i) Not later than three Trading Days after any Conversion Date, the Company will deliver to the Holder (A) a certificate or certificates for the Shares of Common Stock 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 and (B) a bank check in the amount of accrued and unpaid interest (if the Company has

timely elected or is required to pay accrued interest in cash). 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 Conversion Notice such certificate or certificates are not delivered to or as directed by the applicable Holder by the fifth 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 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 $5,000 of principal amount being converted, $50 per Trading Day (increasing to $100 per Trading Day after 3 Trading Days and increasing to $200 per Trading Day 6 Trading Days after such damages begin to accrue) for each Trading Day after such third Trading Day until such certificates are delivered. 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 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 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) 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 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 $0.65 (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, including interest thereon), (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. 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.

(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 VWAP 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 VWAP 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 convert, exercise, adjust or reset any Laurus Securities into Common Stock or 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 then Set Price (“Dilutive Issuance”), as adjusted hereunder (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 and shall be subject to adjustment hereunder), then the Set Price shall be reduced to equal the effective conversion, exchange or purchase price for such Common Stock or Common Stock Equivalents (including any reset provisions thereof) at issue; provided, however, with respect to the Laurus Securities only, any adjustment hereunder shall be on a one for one basis, that is, if the holder thereof converts, exercises or is granted an adjustment or reset with respect to any portion of the Laurus Securities, the adjustment to the Set Price hereunder shall be only with respect to an equivalent principal amount of this Debenture (the Holder, in its sole discretion, shall determine which principal amount is adjusted). Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued, adjusted or reset. 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) If the Company, at any time while Debentures are outstanding, shall distribute to all holders of Common Stock (and not to Holders) evidences of its indebtedness or assets or rights or warrants to subscribe for or purchase any security, then in each such case the Set Price shall be determined by multiplying such 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 Holders 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.

(vi) [RESERVED]

(vii) 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.

(viii) Whenever the Set Price is adjusted pursuant to any of Section 4(c)(ii) - (v), the Company shall promptly mail to each Holder a notice setting forth the Set Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(ix) 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 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.

(x) Fundamental Transaction/Change of Control. 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 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 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 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 (c) and insuring that this Debenture (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. If a Change of Control Transaction occurs, including a Fundamental Transaction that constitutes a Change of Control Transaction, then at the request of the Holder delivered before the 90th day after such Fundamental Transaction, 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 Transaction), equal to the 100% of the remaining unconverted principal amount of this Debenture on the date of such request, plus all accrued and unpaid interest thereon, plus all other accrued and unpaid amounts due hereunder.

(xi) 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) other than the SLD Debentures, upon the exercise of or conversion of any convertible securities, options or warrants issued and outstanding on the Closing 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.

(d) 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 and payment of interest on 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 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 Underlying Shares Registration Statement has been declared effective under the Securities Act, registered for public sale in accordance with such Underlying Shares Registration Statement.

(c) 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.

(d) The issuance of certificates for shares of the Common Stock on conversion of the Debentures shall be made without charge to the Holders thereof 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 such Debentures 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.

(e) Any and all notices or other communications or deliveries to be provided by the Holders hereunder, including, without limitation, any Conversion Notice, shall be in writing and delivered personally, by facsimile, sent by a nationally recognized overnight courier service or sent by certified or registered mail, postage prepaid, addressed to the Company, at the address set forth above, facsimile number (▇▇▇) ▇▇▇-▇▇▇▇, Attn: ▇▇▇▇ ▇▇▇▇▇▇ or such other address or facsimile number as the Company may specify for such purposes by notice to the Holders delivered in accordance with this Section. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile, sent by a nationally recognized overnight courier service or sent by certified or registered mail, postage prepaid, addressed to each Holder at the facsimile telephone number or address of such Holder appearing on the books of the Company, or if no such facsimile telephone number or address appears, at the principal place of business of the Holder. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section prior to 5:30 p.m. (New York City time), (ii) the date after the date

of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section later than 5:30 p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York City time) on such date, (iii) four days after deposit in the United States mail, (iv) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service, or (v) upon actual receipt by the party to whom such notice is required to be given.
