(together with its successors, representatives, and permitted assigns, the “Holder”), in accordance with the terms hereinafter provided, the principal amount of Two Hundred Fifty Thousand Dollars ($250,000.00), together with interest thereon. Concurrently with the issuance of this Note, the Maker is issuing separate promissory notes (the “Other Notes”) to separate purchasers (the “Other Holders”) pursuant to the Note and Warrant Purchase Agreement dated as of November 3, 2004 (the “Purchase Agreement”) by and among the Maker and the purchasers listed therein.

All payments under or pursuant to this Note shall be made in United States Dollars in immediately available funds to the Holder at the address of the Holder first set forth above or at such other place as the Holder may designate from time to time in writing to the Maker or by wire transfer of funds to the Holder’s account, instructions for which are attached hereto as Exhibit A. The outstanding principal balance of this Note shall be due and payable on December 31, 2006 (the “Maturity Date”) or at such earlier time as provided herein.

ARTICLE I

Section 1.1 Purchase Agreement. This Note has been executed and delivered pursuant to the Purchase Agreement. Capitalized terms used and not otherwise defined herein shall have the meanings set forth for such terms in the Purchase Agreement.

Section 1.2 Interest; Payment of Interest. Beginning on the issuance date of this Note (the “Issuance Date”), the outstanding principal balance of this Note shall bear interest, in arrears, at a rate per annum equal to seven percent (7%), increasing to eight percent (8%) on July 1, 2005 and ten percent (10%) on April 1, 2006 through the Maturity Date. Interest shall be payable on a quarterly basis on each Principal Payment Date (as defined below) commencing on June 30, 2005. Interest shall be computed on the basis of a 360-day year of twelve (12) 30-day months and shall accrue commencing on the Issuance Date. Furthermore, upon the occurrence of an Event of Default (as defined in Section 2.1 hereof), then to the extent permitted by law, the Maker will pay interest to the Holder, payable on demand, on the outstanding principal balance of the Note from the date of the Event of Default until such Event of Default is cured at the rate equal to the lesser of the interest rate then in effect plus two percent (2%) and the maximum applicable legal rate per annum (the “Default Rate”).

Section 1.3 Payment of Principal. Commencing on June 30, 2005 and continuing thereafter on a quarterly basis (each, a “Quarterly Determination Period”) on each of September 30, 2005, December 31, 2005, March 31, 2006, June 30, 2006, September 30, 2006 and December 31, 2006 (each, a “Principal Payment Date”), the Maker shall pay an amount equal to one-seventh (1/7) of the then outstanding principal balance of the Note (the “Principal Installment Amount”), plus accrued interest thereon (the “Interest Installment Amount”) provided, that, any remaining outstanding principal amount plus all accrued but unpaid interest shall be paid in full on December 31, 2006. The Maker may pay such Principal Installment Amount in cash or registered shares of the Maker’s common stock, par value $0.0001 per share (the “Common Stock”). The Maker shall notify the Holder in writing five (5) Trading Days prior to the Principal Payment Date (the “Notification Date”) of its election to pay the Principal Installment Amount and Interest Installment Amount in cash or registered shares of Common Stock, or any combination thereof, at the Maker’s discretion. If the Maker elects to pay the Principal Installment Amount and the Interest Installment Amount in cash such amount shall be wired in immediately available funds on the Principal Payment Date. If the Maker elects to pay the Principal Installment Amount and the Interest Installment Amount in registered shares of Common Stock, the Registration Statement must be effective and the number of registered shares of Common Stock to be issued to the Holder shall be an amount equal to the Principal Installment Amount and the Interest Installment Amount divided by ninety percent (90%) of the average of the twenty (20) lowest Volume Weighted Average Prices of the Maker’s Common Stock, as reported on the OTC Bulletin Board, for the applicable Quarterly Determination Period, excluding the Trading Days occurring on and after the Notification Date for such Quarterly Determination Period. The Maker shall not issue more than six million (6,000,000) shares of its Common Stock (“Share Cap Amount”) in the aggregate in payment of Principal Installment Amounts and Interest Installment Amounts under this Note and the Other Notes. Any payment of Principal Installment Amounts and Interest Installment Amounts in excess of the Share Cap Amount shall be paid in cash.

Section 1.4 Payment on Non-Business Days. Whenever any payment to be made shall be due on a Saturday, Sunday or a public holiday under the laws of the State of New York, such payment may be due on the next succeeding business day and such next succeeding day shall be included in the calculation of the amount of accrued interest payable on such date.

ARTICLE III

DELIVERY OF COMMON STOCK; PREPAYMENT

Section 3.1 Delivery of Common Stock.

(a) On the Principal Payment Date, the Maker or its designated transfer agent, as applicable, shall issue and deliver to the Depository Trust Company (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) as specified by the Holder, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. In the alternative, the Maker shall deliver to the Holder by express courier a certificate or certificates which shall be free of restrictive legends and trading restrictions (other than those required by Section 5.1 of the Purchase Agreement) representing the number of shares of Common Stock being issued in payment of the Principal Installment Amount and the Interest Installment Amount on the Principal Payment Date. Notwithstanding the foregoing to the contrary, the Maker or its transfer agent shall only be obligated to issue and deliver the shares to the DTC on the Holder’s behalf via DWAC (or certificates free of restrictive legends) if such conversion is in connection with a sale and the Holder has complied with the applicable prospectus delivery requirements.

(b) The Maker understands that a delay in the delivery of the shares of Common Stock beyond the Principal Payment Date could result in economic loss to the Holder. If the Maker fails to deliver to the Holder such shares via DWAC or a certificate or certificates pursuant to this Section hereunder by the Principal Payment Date, the Maker shall pay to such Holder, in cash, an amount per Trading Day for each Trading Day until such shares are delivered via DWAC or certificates are delivered, together with interest on such amount at the Default Rate, accruing until such amount and any accrued interest thereon is paid in full, equal to the greater of (A) (i) 1% of the aggregate Principal Installment Amount of the Notes being repaid for the first five (5) Trading Days after the Principal Payment Date and (ii) 2% of the aggregate Principal Installment Amount of the Notes being repaid for each Trading Day thereafter and (B) $2,000 per day (which amount shall be paid as liquidated damages and not as a penalty). Nothing herein shall limit a Holder’s right to pursue actual damages for the Maker’s failure to deliver certificates representing shares of Common Stock 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).

(c) Issue Taxes. The Maker shall pay any and all issue and other taxes, excluding federal, state or local income taxes, that may be payable in respect of any issue or delivery of shares of Common Stock in payment of this Note pursuant thereto.

(d) Fractional Shares. No fractional shares of Common Stock shall be issued in payment of this Note. In lieu of any fractional shares to which the Holder would otherwise be entitled, the Maker shall pay cash equal to the product of such fraction multiplied by the average of the Volume Weighted Average Prices of the Common Stock for the five (5) consecutive Trading Days immediately preceding the Principal Payment Date.

(e) Reservation of Common Stock. The Maker shall at all times when this Note shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, six million (6,000,000) shares of Common Stock as shall from time to time be sufficient to effect the payment of this Note and all interest accrued thereon. The Maker shall, from time to time in accordance with the Delaware General Corporation Law, increase the authorized number of shares of Common Stock if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Maker’s obligations under this Section 3.1(e).

(f) Regulatory Compliance. If any shares of Common Stock to be reserved for the purpose of repayment of this Note or any interest accrued thereon require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Maker shall, at its sole cost and expense, in good faith and as expeditiously as possible, endeavor to secure such registration, listing or approval, as the case may be.

Section 3.2 Ownership Cap and Certain Conversion Restriction. Notwithstanding anything to the contrary set forth in Section 3 of this Note, at no time may the Maker issue shares of Common Stock in payment of a quarterly Principal Installment Amount if the number of shares of Common Stock to be issued would exceed, when aggregated with all other shares of Common Stock owned by the Holder at such time, the number of shares of Common Stock which would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules thereunder) more than 9.9% of all of the Common Stock outstanding at such time.

Section 3.3 Prepayment.

(a) Prepayment Upon an Event of Default. Notwithstanding anything to the contrary contained herein, upon the occurrence of an Event of Default described in Sections 2.1(c)-(j) hereof, the Holder shall have the right, at such Holder’s option, to require the Maker to prepay in cash all or a portion of this Note at a price equal to the Triggering Event Prepayment Price (as defined in Section 3.3(c) below) applicable at the time of such request (the “Event of Default Prepayment Price”). Nothing in this Section 3.3(a) shall limit the Holder’s rights under Section 2.2 hereof.

(b) Prepayment Option Upon Major Transaction. In addition to all other rights of the Holder contained herein, simultaneous with the occurrence of a Major Transaction (as defined below), the Holder shall have the right, at the Holder’s option, to require the Maker to prepay all or a portion of the Holder’s Notes in cash at a price equal to one hundred percent (100%) of the aggregate principal amount of this Note plus all accrued and unpaid interest (the “Major Transaction Prepayment Price”).

(c) Prepayment Option Upon Triggering Event. In addition to all other rights of the Holder contained herein, after a Triggering Event (as defined below), the Holder shall have the right, at the Holder’s option, to require the Maker to prepay all or a portion of the Holder’s Notes in cash at a price equal to one hundred percent (100%) of the aggregate principal amount of this Note plus all accrued and unpaid interest (the “Triggering Event Prepayment Price,” and, collectively with the “Major Transaction Prepayment Price,” the “Prepayment Price”).

(d) Intentionally Omitted.

(e) "Major Transaction.” A “Major Transaction” shall be deemed to have occurred at such time as any of the following events:

(i) the consolidation, merger or other business combination of the Maker with or into another Person (as defined in Section 4.13 hereof) (other than (A) pursuant to a migratory merger effected solely for the purpose of changing the jurisdiction of incorporation of the Maker or (B) a consolidation, merger or other business combination in which holders of the Maker’s voting power immediately prior to the transaction continue after the transaction to hold, directly or indirectly, the voting power of the surviving entity or entities necessary to elect a majority of the members of the board of directors (or their equivalent if other than a corporation) of such entity or entities);

(ii) the sale or transfer of more than fifty percent (50%) of the Maker’s assets (based on the fair market value as determined in good faith by the Maker’s Board of Directors) other than inventory in the ordinary course of business in one or a related series of transactions; or

(iii) closing of a purchase, tender or exchange offer made to the holders of more than fifty percent (50%) of the outstanding shares of Common Stock in which more than fifty percent (50%) of the outstanding shares of Common Stock were tendered and accepted; or

(iv) the issuance by the Maker of shares of its Common Stock in one or a series of related transactions in excess of forty percent (40%) of its shares of Common Stock outstanding on the [Closing Date].

(f) "Triggering Event.” A “Triggering Event” shall be deemed to have occurred at such time as any of the following events:

(i) so long as any Notes are outstanding, the effectiveness of the Registration Statement, after it becomes effective, (i) lapses for any reason (including, without limitation, the issuance of a stop order) or (ii) is unavailable to the Holder for sale of the shares of Common Stock, and such lapse or unavailability continues for a period of twenty (20) consecutive Trading Days, and the shares of Common Stock which may be issued in payment of the Holder’s Notes cannot be sold in the public securities market pursuant to Rule 144(k), provided that the cause of such lapse or unavailability is not due to factors primarily within the control of the Holder of the Notes; and provided further that a Triggering Event shall not have occurred if and to the extent the Maker exercised its rights set forth in Sections 3(m) or 3(n) of the Registration Rights Agreement; or

(ii) the suspension from listing, without subsequent listing on any one of, or the failure of the Common Stock to be listed on at least one of the OTC Bulletin Board, Nasdaq National Market, Nasdaq SmallCap Market, The New York Stock Exchange, Inc. or The American Stock Exchange, Inc., for a period of five (5) consecutive Trading Days.

(f) Intentionally Omitted.

(g) Mechanics of Prepayment at Option of Holder Upon Major Transaction. No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Major Transaction, but not prior to the public announcement of such Major Transaction, the Maker shall deliver written notice thereof via facsimile and overnight courier (“Notice of Major Transaction”) to the Holder of this Note. At any time after receipt of a Notice of Major Transaction (or, in the event a Notice of Major Transaction is not delivered at least ten (10) days prior to a Major Transaction, at any time within ten (10) days prior to a Major Transaction), any holder of the Notes then outstanding may require the Maker to prepay, effective immediately prior to the consummation of such Major Transaction, all of the holder’s Notes then outstanding by delivering written notice thereof via facsimile and overnight courier (“Notice of Prepayment at Option of Holder Upon Major Transaction”) to the Maker, which Notice of Prepayment at Option of Holder Upon Major Transaction shall indicate (i) the number of Notes that such holder is electing to prepay and (ii) the applicable Major Transaction Prepayment Price, as calculated pursuant to Section 3.3(b) above.

(h) Mechanics of Prepayment at Option of Holder Upon Triggering Event. Within one (1) business day after the occurrence of a Triggering Event, the Maker shall deliver written notice thereof via facsimile and overnight courier (“Notice of Triggering Event”) to each holder of the Notes. At any time after the earlier of a holder’s receipt of a Notice of Triggering Event and such holder becoming aware of a Triggering Event, any holder of this Note and the Other Notes then outstanding may require the Maker to prepay all of the Notes on a pro rata basis by delivering written notice thereof via facsimile and overnight courier (“Notice of Prepayment at Option of Holder Upon Triggering Event”) to the Maker, which Notice of Prepayment at Option of Holder Upon Triggering Event shall indicate (i) the amount of the Note that such holder is electing to have prepaid and (ii) the applicable Triggering Event Prepayment Price, as calculated pursuant to Section 3.3(c) above. A holder shall only be permitted to require the Maker to prepay the Note pursuant to Section 3.3 hereof for the greater of a period of ten (10) days after receipt by such holder of a Notice of Triggering Event or for so long as such Triggering Event is continuing.

(i) Intentionally Omitted.

(j) Payment of Prepayment Price. Upon the Maker’s receipt of a Notice(s) of Prepayment at Option of Holder Upon Triggering Event or a Notice(s) of Prepayment at Option of Holder Upon Major Transaction from any holder of the Notes, the Maker shall immediately notify each holder of the Notes by facsimile of the Maker’s receipt of such Notice(s) of Prepayment at Option of Holder Upon Triggering Event or Notice(s) of Prepayment at Option of Holder Upon Major Transaction and each holder which has sent such a notice shall promptly submit to the Maker such holder’s certificates representing the Notes which such holder has elected to have prepaid. The Maker shall deliver the applicable Triggering Event Prepayment Price, in the case of a prepayment pursuant to Section 3.3(h), to such holder within five (5) business days after the Maker’s receipt of a Notice of Prepayment at Option of Holder Upon Triggering Event and, in the case of a prepayment pursuant to Section 3.3(g), the Maker shall deliver the applicable Major Transaction Prepayment Price immediately prior to the consummation of the Major Transaction; provided that a holder’s original Note shall have been so delivered to the Maker; provided further that if the Maker is unable to prepay all of the Notes to be prepaid, the Maker shall prepay an amount from each holder of the Notes being prepaid equal to such holder’s pro-rata amount (based on the number of Notes held by such holder relative to the number of Notes outstanding) of all Notes being prepaid. If the Maker shall fail to prepay all of the Notes submitted for prepayment (other than pursuant to a dispute as to the arithmetic calculation of the Prepayment Price), in addition to any remedy such holder of the Notes may have under this Note and the Purchase Agreement, the applicable Prepayment Price payable in respect of such Notes not prepaid shall bear interest at the rate of two percent (2%) per month (prorated for partial months) until paid in full. Until the Maker pays such unpaid applicable Prepayment Price in full to a holder of the Notes submitted for prepayment, such holder shall have the option (the “Void Optional Prepayment Option”) to, in lieu of prepayment, require the Maker to promptly return to such holder(s) all of the Notes that were submitted for prepayment by such holder(s) under this Section 3.3 and for which the applicable Prepayment Price has not been paid, by sending written notice thereof to the Maker via facsimile (the “Void Optional Prepayment Notice”). Upon the Maker’s receipt of such Void Optional Prepayment Notice(s) and prior to payment of the full applicable Prepayment Price to such holder, (i) the Notice(s) of Prepayment at Option of Holder Upon Triggering Event or the Notice(s) of Prepayment at Option of Holder Upon Major Transaction, as the case may be, shall be null and void with respect to those Notes submitted for prepayment and for which the applicable Prepayment Price has not been paid, and (ii) the Maker shall immediately return any Notes submitted to the Maker by each holder for prepayment under this Section 3.3(j) and for which the applicable Prepayment Price has not been paid. A holder’s delivery of a Void Optional Prepayment Notice and exercise of its rights following such notice shall not effect the Maker’s obligations to make any payments which have accrued prior to the date of such notice. Payments provided for in this Section 3.3 shall have priority to payments to other stockholders in connection with a Major Transaction.

(k) Maker’s Prepayment Option. At any time and from time to time after the Issuance Date, the Maker may prepay in cash all or any portion of the outstanding principal amount of this Note, plus any accrued and unpaid interest thereon, upon ten (10) business days prior written notice to the Holder (the “Maker Prepayment Notice”) at a cash price equal to one hundred percent (100%) of the outstanding principal amount of this Note plus any interest accrued and outstanding thereon (the “Maker Prepayment Price”). The Maker may not deliver a Maker Prepayment Notice to the Holder unless the Maker has clear and good funds for a minimum of the amount it intends to prepay in a bank account controlled by the Maker. The Maker Prepayment Notice shall state the date of prepayment (the “Maker Prepayment Date”), the Maker Prepayment Price, the amount of the Note of such Holder to be prepaid, the amount of accrued and unpaid interest through the Maker Prepayment Date and shall call upon the Holder to surrender to the Maker on the Maker Prepayment Date at the place designated in the Maker Prepayment Notice such Holder’s Note. The Maker Prepayment Date shall be no more than ten (10) Trading Days after the date on which the Holder is notified of the Maker’s intent to prepay the Note (the “Maker Prepayment Notice Date”). If the Maker fails to pay the Maker Prepayment Price by the eleventh (11^th) trading day following the Maker Prepayment Notice Date, the prepayment will be declared null and void and the Maker shall lose its right to deliver a Maker Prepayment Notice to the Holder in the future. On or after the Maker Prepayment Date, the Holder shall surrender the Notes called for prepayment to the Maker at the place designated in the Maker Prepayment Notice and shall thereupon be entitled to receive payment of the Maker Prepayment Price.

Section 3.4 No Rights as Shareholder. Nothing contained in this Note shall be construed as conferring upon the Holder, prior to the payment of this Note in shares of Common Stock, the right to vote or to receive dividends or to consent or to receive notice as a shareholder in respect of any meeting of shareholders for the election of directors of the Maker or of any other matter, or any other rights as a shareholder of the Maker.
