          FOR VALUE RECEIVED, Stinger Systems, Inc., a Nevada corporation (the “Company”), hereby promises to pay to the order of CASTLERIGG MASTER INVESTMENTS LTD. or registered assigns (“Holder”) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate from the date set out above as the Original Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon an Interest Date (as defined below) or the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Amended and Restated Senior Secured Convertible Note (including all Senior Secured Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) amends, supplements, modifies and completely restates and supersedes the Senior Secured

Convertible Note, with an original issuance date August 3, 2007, issued by the Company to the Holder in the original Principal amount of $3,000,000.00, but shall not, except as specifically amended hereby or as set forth in the 2008 Securities Purchase Agreement (as defined below), constitute a release, satisfaction or novation of any of the obligations under any other Transaction Document (as defined in the Securities Purchase Agreement). This Note is one of an issue of Amended and Restated Senior Secured Convertible Notes issued pursuant to Section 1(a) of the 2008 Securities Purchase Agreement on the Amendment Date (collectively, the “Notes” and such other Amended and Restated Senior Secured Convertible Notes, the “Other Notes”). Certain capitalized terms used herein are defined in Section 30.

          (1) PAYMENTS OF PRINCIPAL. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges, if any, on such Principal and Interest. The “Maturity Date” shall be August 3, 2010, as may be extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1 or any event shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1 that with the passage of time and the failure to cure would result in an Event of Default and (ii) through the date that is ten (10) Business Days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5(b)) is delivered prior to the Maturity Date. Other than as specifically permitted by this Note, the Company may not prepay any portion of the outstanding Principal, accrued and unpaid Interest or accrued and unpaid Late Charges on Principal and Interest, if any.

          (2) INTEREST; INTEREST RATE. (a) Interest on this Note shall commence accruing on April 1, 2008 and shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30) day months and shall be payable in arrears for each Calendar Quarter on the first day of the succeeding Calendar Quarter during the period beginning on the Issuance Date and ending on, and including, the Maturity Date (each, an “Interest Date”) with the first Interest Date being July 1, 2008. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in shares of Common Stock (“Interest Shares”) so long as there has been no Equity Conditions Failure; provided however, that the Company may, at its option following notice to the Holder, pay Interest on any Interest Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest Shares. The Company shall deliver a written notice (each, an “Interest Election Notice”) to each holder of the Notes on or prior to the Interest Notice Due Date (the date such notice is delivered to all of the holders, the “Interest Notice Date”) which notice (1) either (A) confirms that Interest to be paid on such Interest Date shall be paid entirely in Interest Shares or (B) elects to pay Interest as Cash Interest or a combination of Cash Interest and Interest Shares and specifies the amount of Interest that shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares and (2) certifies that there has been no Equity Conditions Failure; provided, however, that the Company shall not be entitled to pay any portion of Interest on an Interest Date in Interest Shares in excess of the Holder Pro Rata Amount of the applicable Volume Limitation. If any portion of Interest for a particular Interest Date shall be paid in Interest Shares, then the Company shall pay to the Holder, in accordance with Section 2(b), a number of shares of Common Stock equal to (x) the amount of Interest payable on the applicable Interest Date in

Interest Shares divided by (y) the applicable Interest Conversion Price. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable shares of Common Stock (rounded to the nearest whole share). If the Equity Conditions are not satisfied as of the Interest Notice Date, then unless the Company has elected to pay such Interest in cash, the Interest Notice shall indicate that unless the Holder waives the Equity Conditions, the Interest shall be paid in cash. If the Equity Conditions were satisfied as of the Interest Notice Date but the Equity Conditions are no longer satisfied at any time prior to the Interest Date, the Company shall provide the Holder a subsequent notice to that effect indicating that unless the Holder waives the Equity Conditions, the Interest shall be paid in cash.

               (b) When any Interest Shares are to be paid on an Interest Date, the Company shall (i) (A) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and such action is not prohibited by applicable law or regulation or any applicable policy of DTC, credit such aggregate number of Interest Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (B) if the foregoing shall not apply, issue and deliver on the applicable Interest Date, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least two (2) Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled and (ii) with respect to each Interest Date, pay to the Holder, in cash by wire transfer of immediately available funds, the amount of any Cash Interest. Notwithstanding the foregoing, the Company shall not be entitled to pay Interest in Interest Shares and shall be required to pay such Interest in cash as Cash Interest on the applicable Interest Date if, unless waived in writing by the Holder, there has been an Equity Conditions Failure. If an Event of Default or Equity Conditions Failure occurs during the Interest Measuring Period, then on the Interest Date, at the Holder’s option, the Holder may require the Company to pay all or any specified portion of the Interest due on the applicable Interest Date as Cash Interest.

               (c) From and after the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to fifteen percent (15.0%) per annum. In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default. The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Interest Shares.

          (3) CONVERSION OF NOTES. This Note shall be convertible into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), on the terms and conditions set forth in this Section 3.

               (a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

               (b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

                    (i) “Conversion Amount” means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made, (B) accrued and unpaid Interest with respect to such Principal and (C) accrued and unpaid Late Charges with respect to such Principal and Interest.

                    (ii) “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, $0.6342, subject to adjustment as provided herein.

               (c) Mechanics of Conversion.

                    (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and (B) if required by Section 3(c)(iii), surrender this Note to a common carrier for delivery to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the first (1^st) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation (the “Conversion Confirmation”) of receipt of such Conversion Notice to the Holder and the Company’s Transfer Agent. On or before the (2^nd) second Business Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock (including any Interest Shares) to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock (including any Interest Shares) to which the Holder shall be entitled. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver

to the holder a new Note (in accordance with Section 20(d)) representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

                    (ii) Company’s Failure to Timely Convert. If the Company shall fail to issue a certificate to the Holder or credit the Holder’s balance account with DTC, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is three (3) Trading Days after the Conversion Date (a “Conversion Failure”), then (A) the Company shall pay damages to the Holder for each Trading Day of such Conversion Failure in an amount equal to 1.5% of the product of (I) the sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (II) the Closing Sale Price of the Common Stock on the Share Delivery Date and (B) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the foregoing, if within three (3) Trading Days after the Company’s receipt of the facsimile copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon such holder’s conversion of any Conversion Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (A) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price"), at which point the Company’s obligation to issue and deliver such certificate or to credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon such Holder’s conversion of any Conversion Amount shall terminate, or (B) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (1) such number of shares of Common Stock, times (2) the Closing Bid Price on the Conversion Date.

                    (iii) Registration; Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”). The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note for all purposes, including, without limitation, the right to receive payments of Principal and Interest hereunder, notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only by registration of such assignment or sale on the Register. Upon its receipt of a request to assign or sell all or part of any Registered Note by a Holder, the Company shall record the information contained therein in

the Register and issue one or more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 20.

                    (iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 25.

               (d) Limitations on Conversions.

                    (i) Beneficial Ownership. The Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holder’s affiliates) would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the number of shares of 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 Note 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 Note 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 Notes or 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 3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Section 3(d)(i), 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-K, Form 10-Q, Form 8-K or other public filing with the Securities Exchange Commission, as the case may be (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day 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 Note, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to

any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes.

                    (ii) Principal Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon conversion of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants without breaching the Company’s obligations under the rules or regulations of any applicable Eligible Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of such Eligible Market for issuances of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Required Holders. Until such approval or written opinion is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (each, a “Purchaser” and collectively the “Purchasers”) shall be issued in the aggregate, upon conversion or exercise or otherwise, as applicable, of Notes or Warrants, shares of Common Stock in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to any Purchaser pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes issued to all of the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Notes shall convert all of such holder’s Notes into a number of shares of Common Stock which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

          (4) RIGHTS UPON EVENT OF DEFAULT.

               (a) Event of Default. Each of the following events shall constitute an “Event of Default”:

                    (i) the failure of the applicable Registration Statement required to be filed pursuant to the Registration Rights Agreement to be declared effective by the SEC on or prior to the date that is sixty (60) days after the applicable Effectiveness Deadline (as defined in the Registration Rights Agreement), or, while the applicable Registration Statement is required to be maintained effective pursuant to the terms of the Registration Rights Agreement, the effectiveness of the applicable Registration Statement lapses for any reason (including, without limitation, the issuance of a stop order) or is unavailable to any holder of the Notes for sale of all of such holder’s Registrable Securities (as defined in the Registration Rights

Agreement) in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of five (5) consecutive days or for more than an aggregate of twenty (20) days in any 365-day period (other than days during an Allowable Grace Period (as defined in the Registration Rights Agreement));

                    (ii) the suspension from trading or failure of the Common Stock to be listed on an Eligible Market for a period of five (5) consecutive Trading Days or for more than an aggregate of ten (10) Trading Days in any 365-day period;

                    (iii) the Company’s (A) failure to cure a Conversion Failure by delivery of the required number of shares of Common Stock within ten (10) Business Days after the applicable Conversion Date or (B) notice, written or oral, to any holder of the Notes, including by way of public announcement or through any of its agents, at any time, of its intention not to comply with a request for conversion of any Notes into shares of Common Stock that is tendered in accordance with the provisions of the Notes, other than pursuant to Section 3(d);

                    (iv) at any time following the tenth (10^th) consecutive Business Day that the Holder’s Authorized Share Allocation is less than the number of shares of Common Stock that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise);

                    (v) the Company’s failure to pay to the Holder any amount of Principal, Interest, Late Charges or other amounts when and as due under this Note (including, without limitation, the Company’s failure to pay any redemption payments or amounts hereunder) or any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby to which the Holder is a party, except, in the case of a failure to pay Interest and Late Charges when and as due, in which case only if such failure continues for a period of at least five (5) Business Days;

                    (vi) any default under, redemption of or acceleration prior to maturity of any Indebtedness of the Company or any of its Subsidiaries (as defined in Section 3(a) of the Securities Purchase Agreement) other than with respect to any Other Notes;

                    (vii) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal, foreign or state law for the relief of debtors (collectively, “Bankruptcy Law”), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a “Custodian”), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;

                    (viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company or any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Subsidiaries or (C) orders the liquidation of the Company or any of its Subsidiaries;

                    (ix) a final judgment or judgments for the payment of money aggregating in excess of (A) $100,000 are rendered against the Company or any of its Subsidiaries or (B) $50,000 are rendered against any of the officers or directors of the Company or any of its Subsidiaries, and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the amounts set forth above so long as the Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

                    (x) the Company breaches any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition of any Transaction Document which is curable, only if such breach continues for a period of at least ten (10) consecutive Business Days;

                    (xi) any breach or failure in any respect to comply with either of Sections 8 or 17 of this Note; or

                    (xii) any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes.

               (b) Redemption Right. Upon the occurrence of an Event of Default, the Company shall within one (1) Business Day deliver written notice thereof via facsimile and overnight courier (an “Event of Default Notice”) to the Holder. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (A) the sum of the Conversion Amount to be redeemed together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest and (B) the Redemption Premium and (ii) the product of (A) the Conversion Rate with respect to such sum of the Conversion Amount together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the product of (1) the Equity Value Redemption Premium and (2) the greatest Closing Sale Price of the Common Stock beginning on the date immediately preceding such Event of Default and ending on the date the Holder delivers the Event of Default Redemption Notice (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance

with the provisions of Section 14. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any Redemption Premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

          (5) RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

               (a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes then outstanding held by such holder, having similar conversion rights and having similar ranking to the Notes, and satisfactory to the Required Holders and (ii)  the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market (a “Public Successor Entity”). Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Company’s Common Stock (or other securities, cash, assets or other property) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity), as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note.

               (b) Redemption Right. (i) No sooner than fifteen (15) Trading Days nor later than ten (10) Trading Days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”). At any time during the period beginning after the Holder’s receipt of a Change of Control Notice and ending twenty (20) Trading Days after the date of the consummation of such Change of

Control, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company in cash at a price equal to the greater of (i) 130% of the sum of (x) the Conversion Amount being redeemed and (y) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest through the date of such redemption payment and (ii) the product of (x) the Equity Value Redemption Premium and (y) the sum of (1) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration per Common Share to be paid to the holders of the Common Shares upon consummation of the Change of Control (any such non-cash consideration consisting of marketable securities to be valued at the higher of the Closing Sale Price of such securities as of the Trading Day immediately prior to, the Closing Sale Price as of the Trading Day immediately following the public announcement of such proposed Change of Control and the Closing Sale Price of the Common Stock immediately prior to the public announcement of such proposed Change of Control) by (II) the Conversion Price plus (2) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest through the date of such redemption payment, (the “Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 14 and shall have priority to payments to stockholders in connection with a Change of Control. To the extent redemptions required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any Change of Control redemption premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

                    (ii) Notwithstanding anything to the contrary contained above, if the Successor Entity in a Change of Control transaction is a Public Successor Entity and has a market capitalization in excess of $350 million as of the Change of Control Notice Due Date (as defined below) and the consideration being paid to the holders of Common Stock in such Change of Control consists solely of its publicly traded common stock, the Successor Entity may, in lieu of paying the Change of Control Redemption Price in cash, elect to pay some or all of the Conversion Amount to be redeemed (the “Change of Control Redemption Amount”) to the Holder of this Note by causing the conversion of such Change of Control Redemption Amount, provided there has been no Equity Conditions Failure (other than with respect to clause (vi)(A) of the definition of Equity Condition), in accordance with this Section 5(b) (a “Successor

Conversion”). On or prior to the date which is the tenth (10^th) Trading Day prior to the date of the consummation of the Change of Control transaction (the “Change of Control Notice Due Date”), the Successor Entity shall deliver written notice (each, a “Successor Change of Control Notice” and the date all of the holders receive such notice is referred to as to the “Successor Change of Control Notice Date”), to each holder of Notes, which Successor Change of Control Notice shall (A) state, if applicable, what portion of the Change of Control Redemption Amount of such holder’s Note the Successor Entity elects to have converted upon receipt of a Change of Control Redemption Notice, pursuant to a Successor Conversion (such amount to be converted, the “Successor Conversion Amount”) and (B) state, if applicable, what portion of the Change of Control Redemption Amount the Successor Entity elects to have redeemed, upon receipt of a Change of Control Redemption Notice, or would be required to be redeemed in accordance with the provisions of the Notes and (ii) if some or all of the Change of Control Redemption Amount is to be paid pursuant to a Successor Conversion, certify that the Equity Conditions (other than with respect to clause (vi)(A) of the definition of Equity Condition) have been satisfied as of the date of the Successor Change of Control Notice. Each Successor Change of Control Notice shall be irrevocable. If the Successor Entity does not timely deliver a Successor Change of Control Notice in accordance with this Section 5(b), then the Successor Entity shall be deemed to have delivered an irrevocable Successor Change of Control Notice stating that the entire Change of Control Redemption Price shall be paid in cash. Except as expressly provided in this Section 5(b)(ii), the Company shall convert or redeem the applicable Change of Control Redemption Amount of this Note pursuant to this Section 5(b) and the corresponding Change of Control Redemption Amounts of the Other Notes in the same pro rata proportion pursuant to the corresponding provisions of the Other Notes in the same manner. The Successor Conversion Amount (whether set forth in the Successor Change of Control Notice or by operation of this Section 5(b)) shall be converted in accordance with Section 5(b)(iii) and the Successor Entity Redemption Amount shall be redeemed in accordance with Section 5(b)(i).

                    (iii) Subject to Section 3(d), if the Successor Entity delivers a Successor Change of Control Notice and elects a Successor Conversion in accordance with Section 5(b)(ii), then the applicable Change of Control Redemption Price shall be converted by converting such Change of Control Redemption Price at the Successor Conversion Price (A) on the date of the consummation of the Change of Control if the Change of Control Redemption Notice is received prior to the consummation of the Change of Control or (B) within five (5) Business Days after the Company’s receipt of such Change of Control Redemption Notice otherwise (the “Change of Control Conversion Date”); provided that the Equity Conditions have been satisfied (or waived in writing by the Holder). If the Equity Conditions are not satisfied (or waived in writing by the Holder), then at the option of the Holder designated in writing to the Company and the Successor Entity, the Holder may require the Company to do any one or more of the following: (i) the Company shall redeem all or any part designated by the Holder of the unconverted Successor Conversion Amount (such designated amount is referred to as the “First Redemption Amount”) on the Change of Control Conversion Date and the Company shall pay to the Holder on the Change of Control Conversion Date, by wire transfer of immediately available funds, an amount in cash equal to 130% of such First Redemption Amount, and/or (ii) the Successor Conversion shall be null and void with respect to all or any part designated by the Holder of the unconverted Change of Control Redemption Price and the Holder shall be entitled to all the rights of a holder of this Note with respect to such amount of the Change of Control Redemption Price; provided, however, that the Conversion Price for such

unconverted Change of Control Redemption Price shall thereafter be adjusted to equal the lesser of (A) the Successor Conversion Price as in effect on the date on which the Holder voided the Successor Conversion and (B) the Successor Conversion Price that would be in effect as if the Change of Control was consummated on the date on which the Holder delivers a Conversion Notice. If the Company fails to redeem any First Redemption Amount on or before the Change of Control Conversion Date by payment of such amount on the Change of Control Conversion Date, then the Holder shall have the rights set forth in Section 14 (a) as if the Company failed to pay the applicable Redemption Price and all other rights under this Note (including, without limitation, such failure constituting an Event of Default described in Section 4(a)). Notwithstanding anything to the contrary in this Section 5(b)(iii), but subject to 3(d), until the Company or the Successor Entity, as applicable, delivers the Change of Control Redemption Price to the Holder, the Change of Control Redemption Price may be converted by the Holder into Common Stock pursuant to Section 3. Notwithstanding the foregoing, if the Change of Control Conversion Date occurs after the consummation of the Change of Control, the Successor Entity shall be obligated, in lieu of the Company, to deliver the Change of Control Redemption Price, whether by delivery of the Successor Conversion Amount at the Successor Conversion Price or by delivery of the Change of Control Redemption Amount.

          (6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

               (a) Purchase Rights. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

               (b) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate

with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.

          (7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

               (a) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock deemed to have been issued or sold by the Company in connection with any Excluded Securities) for a consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal to the Conversion Price in effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. For purposes of determining the adjusted Conversion Price under this Section 7(a), the following shall be applicable:

                    (i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities.

                    (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise” shall be equal

to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

                    (iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Subscription Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

                    (iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the

“Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days after the tenth (10^th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

                    (v) Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

                    (vi) Voluntary Adjustment By Company. The Company may at any time during the term of this Note reduce the then current  Conversion Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

               (b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased.

               (c) Other Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder under this Note; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 7.

               (d) Milestone-Related Adjustment. The Conversion Price shall be permanently and cumulatively reduced upon the occurrence of any of the following “Milestone Events” as follows:

                    (1) If the Company shall fail to have achieved any of the following: (A) the sale of 2,500 Units during the period beginning on the Closing Date and ending on March 31, 2008 or (B) a Gross Margin (as defined pursuant to GAAP) in excess of

30% for such Units, each as reported in a Current Report on Form 8-K filed with the SEC no later than May 15, 2008; or

                    (2) If the Company shall fail to have achieved any of the following: (A) the sale of 9,000 Units during the period beginning on the Closing Date and ending on September 30, 2008, (B) a Gross Margin in excess of 35%, each as reported in a Current Report on Form 8-K filed with the SEC no later than November 14, 2008 or (C) EBITDA in excess of zero for the Fiscal Quarter ended on September 30, 2008;

               the Conversion Price shall be reduced to the lesser of (i) the existing Conversion Price and (ii) the Average Market Price as of the date that is ten (10) business days after the date the applicable Milestone Event is publicly reported by the Company in a Current Report on Form 8-K. If the Company (A) does not report on a Current Report on Form 8-K(1) on or prior to May 15, 2008, the number of Units sold between the Closing Date and March 31, 2008 and the Gross Margin for such Units and (B) on or prior to November 14, 2008, the number of Units sold between the Closing Date and September 30, 2008, the Gross Margin for such Units and EBITDA for the Fiscal Quarter ended September 30, 2008 or (C) such information is inconsistent with any such information reported on any Quarterly Report or Annual Report of the Company, a Milestone Event shall be deemed to have occurred.

          (8) COMPANY’S RIGHT OF MANDATORY CONVERSION.

               (a) Mandatory Conversion. If at any time and from and after the one (1) year anniversary of the Effective Date whereby all Registrable Securities have been declared effective (as such terms are defined in the Registration Statement) (the “Mandatory Conversion Eligibility Date”), the arithmetic average of the Weighted Average Price of the Common Stock for twenty (20) Trading Days out of any thirty (30) consecutive Trading Days after the Mandatory Conversion Eligibility Date exceeds (i) 150% of the initial Conversion Price and there has been no Equity Conditions Failure, the Company shall have the right to require the Holder to convert up to 50% of the Conversion Amount of this Note or (ii) 175% of the initial Conversion Price and there has been no Equity Conditions Failure, the Company shall have the right to require the Holder to convert up to 100% of the Conversion Amount of this Note, as designated in the Mandatory Conversion Notice (as defined below) into fully paid, validly issued and nonassessable shares of Common Stock in accordance with Section 3(c) hereof at the Conversion Rate as of the Mandatory Conversion Date (as defined below) (a “Mandatory Conversion”). The Company may exercise its right to require conversion under this Section 8(a) by delivering within not more than twenty (20) Trading Days following the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the “Mandatory Conversion Notice” and the date all of the holders received such notice by facsimile is referred to as the “Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The Mandatory Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in accordance with this Section 8(a), which Trading Day shall be no later than five (5) Business Days following the Mandatory Conversion Notice Date (the “Mandatory Conversion Date”), (ii) the aggregate Conversion Amount, of the Notes subject to mandatory conversion from the Holder and all of the holders of the Notes pursuant to this Section 8 (and analogous provisions under the Other Notes), (iii) the number of

shares of Common Stock to be issued to such Holder on the Mandatory Conversion Date and (iv) that there has been no Equity Conditions Failure; provided, however, that the Company may not effect a Mandatory Conversion under this Section in excess of the Holder Pro Rata Amount of the applicable Mandatory Conversion Volume Limitation. Notwithstanding the foregoing, the Company may effect only one (1) Mandatory Conversion during any twenty (20) consecutive Trading Days. Any shares of Common Stock delivered in connection with a Mandatory Conversion hereunder shall be accompanied by a payment in cash equal to the amount of any accrued and unpaid Interest with respect to such Conversion Amount subject to such Mandatory Conversion and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest.

               (b) Pro Rata Conversion Requirement. If the Company elects to cause a conversion of any Conversion Amount of this Note pursuant to Section 8(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. If the Company elects a Mandatory Conversion of this Note pursuant to Section 8(a) (or similar provisions under the Other Notes) with respect to less than all of the Conversion Amounts of the Notes then outstanding, then the Company shall require conversion of a Conversion Amount from each of the holders of the Notes equal to the product of (i) the aggregate Conversion Amount of Notes which the Company has elected to cause to be converted pursuant to Section 8(a), multiplied by (ii) the fraction, the numerator of which is the sum of the aggregate Original Principal Amount of the Notes purchased by such holder of outstanding Notes and the denominator of which is the sum of the aggregate Original Principal Amount of the Notes purchased by all holders holding outstanding Notes (such fraction with respect to each holder is referred to as its “Conversion Allocation Percentage,” and such amount with respect to each holder is referred to as its “Pro Rata Conversion Amount”); provided, however, that in the event that any holder’s Pro Rata Conversion Amount exceeds the outstanding Principal amount of such holder’s Note, then such excess Pro Rata Conversion Amount shall be allocated amongst the remaining holders of Notes in accordance with the foregoing formula. In the event that the initial holder of any Notes shall sell or otherwise transfer any of such holder’s Notes, the transferee shall be allocated a pro rata portion of such holder’s Conversion Allocation Percentage and the Pro Rata Conversion Amount.

          (9) HOLDER’S RIGHT OF OPTIONAL REDEMPTION. Following each of the one (1) year anniversary of the Issuance Date and the two (2) year anniversary of the Issuance Date, the Holder shall have the right (the “Holder Optional Redemption”), in its sole discretion, to require that the Company to redeem a Principal amount of this Note in an amount up to the Available Redemption Amount plus accrued and unpaid Interest on such Available Redemption Amount plus accrued and unpaid Late Charges with respect to such Principal and Interest (the “Redemption Amount”) by delivering written notice thereof to the Company within five (5) Business Days following each of the above mentioned anniversary dates (a “Holder Optional Redemption Notice” and the date the Holder delivers such notice, the “Holder Optional Redemption Notice Date. The Company shall redeem any Redemption Amounts within five (5) Trading Days of the Holder Optional Redemption Notice Date (the “Optional Redemption Date”) in cash at a price equal to the Redemption Amount (the “Holder Redemption Price”). Redemptions made pursuant to this Section 9 shall be made in accordance with Section 14. No later than one (1) Trading Day following any Optional Redemption Date,

the Company shall file a Current Report on Form 8-K describing the terms of the applicable Holder Optional Redemption.

          (10) HOLDER’S RIGHT OF OPTIONAL CONVERSION/REDEMPTION

               (a) General. At any time and from time to time after the earlier of (i) the Initial Effective Date (as defined in the Registration Rights Agreement) and (ii) the one (1) year anniversary of the Issuance Date, the Holder shall have the right, in its sole discretion, to require that the Company, convert, or, at the Company’s election, redeem all or a portion of the Conversion Amount (the “Conversion/Redemption Amount”) by delivering written notice thereof (a “Holder Optional Conversion/Redemption Notice” and the date the Holder delivers such notice, the “Holder Optional Conversion/Redemption Notice Date”). Within one (1) Business Day of the Holder Optional Conversion/Redemption Notice Date, the Company shall deliver to the Holder a written notice (a “Company Conversion/Redemption Notice” and the date the Holder receives such written notice, the “Company Conversion/Redemption Notice Date”) which notice shall (i) either (A) confirm that the Conversion/Redemption Amount shall be converted (an “Optional Conversion”) in whole or in part or (B)(1) state that the Company elects to redeem (an “Optional Redemption”), in whole or in part, the Conversion/Redemption Amount and (2) specify the portion which the Company elects to redeem pursuant to an Optional Redemption (such amount to be redeemed, the “Optional Redemption Amount”) and the portion, if any, that the Company elects to convert pursuant to an Optional Conversion (such amount also, an “Optional Conversion Amount”) and (ii) if the Conversion/Redemption Amount is to be paid, in whole or in part, pursuant to an Optional Conversion, certify that there has been no Equity Conditions Failure (other than with respect to clause (iv)(A) of the definition of Equity Conditions). Each Company Conversion/Redemption Notice shall be irrevocable. The Company shall redeem and convert any Optional Redemption Amounts and Optional Conversion Amounts within five (5) Trading Days of the Company Conversion/Redemption Notice Date (the “Optional Conversion/Redemption Date”) and shall make the same conversion and redemption decisions as to all the Notes for which the Company has received a Holder Optional Conversion/Redemption Notice. The portion of this Note subject to redemption pursuant to this Section 10 shall be redeemed by the Company in cash at a price equal to the Optional Redemption Amount (the “Holder Optional Redemption Price”).

               (b) Mechanics of Holder Optional Conversion. If the Company delivers a Company Conversion/Redemption Notice electing an Optional Conversion in accordance with Section 10(a), then, on the Optional Conversion/Redemption Date, the Company shall, or shall direct the Transfer Agent to, deliver to the Holder’s account with DTC, or issue the Holder a certificate for, a number of shares of Common Stock equal to the quotient of (A) such Optional Conversion Amount divided by (B) the Optional Conversion Price (the “Optional Conversion Shares”) on the Optional Conversion/Redemption Date. If the Company has elected an Optional Conversion, in whole or in part, and there is an Equity Conditions Failure (other than with respect to clause (iv)(A) of the definition of Equity Conditions) at the Holder Optional Conversion/Redemption Date, then at the option of the Holder designated in writing to the Company, the Holder may require the Company to do either one or both of the following: (A) the Company shall redeem all or any part designated by the Holder of the unconverted Holder Optional Conversion Amount (such designated amount is referred to as the “Holder Designated Redemption Amount”) on such Holder Optional Conversion/Redemption Date and the

Company shall pay to the Holder on such Holder Optional Conversion/Redemption Date by wire transfer of immediately available funds, an amount in cash equal to 125% of such Holder Designated Redemption Amount, and/or (B) the Holder Optional Conversion shall be null and void with respect to all or any part designated by the Holder of the unconverted Holder Optional Conversion Amount and the Holder shall be entitled to all the rights of a holder of this Note with respect to such amount of the Holder Optional Conversion Amount; provided, however, that the Conversion Price for such unconverted Holder Optional Conversion Amount shall thereafter be adjusted to equal the lowest the Optional Conversion Price as in effect during the period beginning on the date on which the Holder voided the Holder Optional Conversion and ending on the date on which the Holder delivers a Conversion Notice relating thereto. If the Company fails to redeem the Holder Designated Redemption Amount on or before the Holder Optional Conversion/Redemption Date by payment of such amount on such Holder Optional Conversion/Redemption Date then the Holder shall have the rights set forth in Section 14(a) as if the Company failed to pay the applicable Holder Optional Redemption Price and all other rights under this Note (including, without limitation, such failure constituting an Event of Default described in Section 4(a)(v)).

               (c) Mechanics of Holder Optional Redemption. Optional Redemptions made pursuant to this Section 10 shall be made in accordance with Section 14.

          (11) SECURITY. This Note and the Other Notes are secured to the extent and in the manner set forth in the Security Documents (as defined in the Securities Purchase Agreement).

          (12) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note.

          (13) RESERVATION OF AUTHORIZED SHARES.

               (a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each of the Notes equal to 130% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 130% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding; provided that at no time shall the number of shares of Common Stock so reserved be less than the number of shares required to be reserved by the previous sentence (without regard to any limitations on conversions) (the “Required Reserve Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the principal amount of the Notes held by each holder

at the Closing (as defined in the Securities Purchase Agreement) or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders.

               (b) Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b), Section 5(b) or Section 9 (each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is three (3) Business Days prior to the Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which is three (3) Business Days after the Company’s receipt of the Holder’s Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven Business Day period.
