Capitalized terms used herein without definition shall have the meanings ascribed to such terms in that certain Securities Purchase Agreement dated as of the date hereof between the Borrower and the Holder (the “Purchase Agreement”).

The following terms shall apply to this Note:

ARTICLE I
INTEREST & AMORTIZATION

1.1(a) Interest Rate. Subject to Sections 4.11 and 5.6 hereof, interest payable on this Note shall accrue from the date hereof to the Maturity Date at a rate per annum (the “Interest Rate”) equal to the “prime rate” published in The Wall Street Journal from time to time, plus two percent (2%). The prime rate shall be increased or decreased as the case may be for each increase or decrease in the prime rate in an amount equal to such increase or decrease in the prime rate; each change to be effective as of the day of the change in such rate. Interest shall be (i) calculated on the basis of a 360 day year, and (ii) payable monthly, in arrears, commencing on March 1, 2005 and on the first business day of each consecutive calendar month thereafter until the Maturity Date (and on the Maturity Date), whether by acceleration or otherwise (each, a “Repayment Date”).

1.1 (b) Interest Rate Adjustment. The Interest Rate shall be calculated on the last business day of each month hereafter until the Maturity Date (each a “Determination Date”) and shall be subject to adjustment as set forth herein. If (i) the Borrower shall have registered the shares of the Borrower’s common stock underlying each of the conversion of the Note and that certain warrant issued to Holder on a registration statement declared effective by the Securities and Exchange Commission (the “SEC”), and (ii) the market price (the “Market Price”) of the Common Stock as reported by Bloomberg, L.P. on the Principal Market (as defined below) for the five (5) trading days immediately preceding a Determination Date exceeds the then applicable Fixed Conversion Price by at least twenty five percent (25%), the Interest Rate for the succeeding calendar month shall automatically be reduced by 200 basis points (200 b.p.) (2.0.%) for each incremental twenty five percent (25%) increase in the Market Price of the Common Stock above the then applicable Fixed Conversion Price. If (i) the Borrower shall not have registered the shares of the Borrower’s common stock underlying the conversion of the Note and that certain warrant issued to Holder on a registration statement declared effective by the SEC and which remains effective, and (ii) the Market Price of the Common Stock as reported by Bloomberg, L.P. on the principal market for the five (5) trading days immediately preceding a Determination Date exceeds the then applicable Fixed Conversion Price by at least twenty five percent (25%), the Interest Rate for the succeeding calendar month shall automatically be decreased by 100 basis points (100 b.p.) (1.0.%) for each incremental twenty five percent (25%) increase in the Market Price of the Common Stock above the then applicable Fixed Conversion Price. Notwithstanding the foregoing (and anything to the contrary contained in herein), in no event shall the Interest Rate be less than zero percent (0%).

1.2 Minimum Monthly Principal Payments. Amortizing payments of the aggregate principal amount outstanding under this Note at any time (the “Principal Amount”) shall begin on August 1, 2005 and shall recur on the first business day of each succeeding month thereafter until the Maturity Date (each, an “Amortization Date”). Subject to Article 3 below, beginning on the first Amortization Date, the Borrower shall make monthly payments to the Holder on each Repayment Date, each in the amount of $50,000.00, together with any accrued and unpaid interest to date on such portion of the Principal Amount plus any and all other amounts which are then owing under this Note, the Purchase Agreement or any other Related Agreement but have not been paid (collectively, the “Monthly Amount”). Any Principal Amount that remains outstanding on the Maturity Date shall be due and payable on the Maturity Date.

ARTICLE II
CONVERSION REPAYMENT

2.1 (a) Payment of Monthly Amount in Cash or Common Stock. Each month by the fifth (5^th) business day prior to each Amortization Date (the “Notice Date”), the Holder shall deliver to Borrower a written notice in the form of Exhibit B attached hereto converting the Monthly Amount payable on the next Repayment Date in either cash or Common Stock, or a combination of both (each, a “Repayment Notice”). If a Repayment Notice is not delivered by the Holder on or before the applicable Notice Date for such Repayment Date, then the Borrower shall pay the Monthly Amount due on such Repayment Date in cash. Any portion of the Monthly Amount paid in cash on a Repayment Date, shall be paid to the Holder an amount equal to 102% of the principal portion of the Monthly Amount due and owing to Holder on the Repayment Date. If the Holder converts all or a portion of the Monthly Amount in shares of Common Stock as provided herein, the number of such shares to be issued by the Borrower to the Holder on such Repayment Date shall be the number determined by dividing (x) the portion of the Monthly Amount to be paid in shares of Common Stock, by (y) the then applicable Fixed Conversion Price. For purposes hereof, the initial “Fixed Conversion Price” means $1.17 (which has been determined on the date of this Note as an amount equal to 102% of the average closing price for the ten (10) trading days immediately prior to the date of this Note).

(b) Monthly Amount Conversion Guidelines. Subject to Sections 2.1(a), 2.2, and 3.2 hereof, the Holder shall convert all or a portion of the Monthly Amount due on each Repayment Date in shares of Common Stock if the average closing price of the Common Stock as reported by Bloomberg, L.P. on the Principal Market for the five (5) trading days immediately preceding such Repayment Date was greater than or equal to 115% of the Fixed Conversion Price, provided, however, that such conversions shall not exceed twenty five percent (25%) of the aggregate dollar trading volume of the Common Stock for the five (5) day trading period immediately preceding delivery of a Notice of Conversion to the Borrower. Any part of the Monthly Amount due on a Repayment Date that the Holder has not converted into shares of Common Stock shall be paid by the Borrower in cash on such Repayment Date. Any part of the Monthly Amount due on such Repayment Date which must be paid in cash (as a result of the closing price of the Common Stock on one or more of the five (5) trading days preceding the applicable Repayment Date being less than 115% of the Fixed Conversion Price) shall be paid in cash, within three (3) business days of the applicable Repayment Date.

2.2 No Effective Registration. Notwithstanding anything to the contrary herein, none of the Borrower’s obligations to the Holder may be converted into Common Stock unless (i) either (x) an effective current Registration Statement (as defined in the Registration Rights Agreement) covering the shares of Common Stock to be issued in connection with satisfaction of such obligations exists or (y) an exemption from registration of the Common Stock is available to pursuant to Rule 144 of the Securities Act and (ii) no Event of Default hereunder exists and is continuing, unless such Event of Default is cured within any applicable cure period or is otherwise waived in writing by the Holder in whole or in part at the Holder’s option.

Any amounts converted by the Holder pursuant to this Section 2.2 shall be deemed to constitute payments of outstanding fees, interest and principal arising in connection with Monthly Amounts for the remaining Repayment Dates, in chronological order.

2.3 Optional Redemption in Cash. The Borrower will have the option of prepaying this Note (“Optional Redemption”) by paying to the Holder a sum of money equal to one hundred thirty percent (130%) of the then outstanding principal amount of this Note together with accrued but unpaid interest thereon and any and all other sums due, accrued or payable to the Holder arising under this Note, the Purchase Agreement, or any Related Agreement (the “Redemption Amount”) outstanding on the day written notice of redemption (the “Notice of Redemption”) is given to the Holder. The Notice of Redemption shall specify the date for such Optional Redemption (the “Redemption Payment Date”) which date shall be seven (7) business days after the date of the Notice of Redemption (the “Redemption Period”). A Notice of Redemption shall not be effective with respect to any portion of this Note for which the Holder has a pending election to convert pursuant to Section 3.1, or for conversions initiated or made by the Holder pursuant to Section 3.1 during the Redemption Period. The Redemption Amount shall be determined as if such Holder’s conversion elections had been completed immediately prior to the date of the Notice of Redemption. On the Redemption Payment Date, the Redemption Amount must be paid in good funds to the Holder. In the event the Borrower fails to pay the Redemption Amount on the Redemption Payment Date as set forth herein, then such Redemption Notice will be null and void.

ARTICLE III
CONVERSION RIGHTS

3.1. Holder’s Conversion Rights. The Holder shall have the right, but not the obligation, to convert all or any portion of the then aggregate outstanding principal amount of this Note, together with interest and fees due hereon, into shares of Common Stock subject to the terms and conditions set forth in this Article III. The Holder may exercise such right by delivery to the Borrower of a written notice of conversion not less than one (1) day prior to the date upon which such conversion shall occur.

3.2 Conversion Limitation. Notwithstanding anything contained herein to the contrary, the Holder shall not be entitled to convert pursuant to the terms of this Note an amount that would be convertible into that number of Conversion Shares which would exceed the difference between the number of shares of Common Stock beneficially owned by such Holder or issuable upon exercise of warrants held by such Holder and 4.99% of the outstanding shares of Common Stock of the Borrower. For the purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and Regulation 13d-3 thereunder. The Holder may void the Conversion Share limitation described in this Section 3.2 upon 75 days prior notice to the Borrower or without any notice requirement upon an Event of Default.

3.3 Mechanics of Holder’s Conversion. (a) In the event that the Holder elects to convert this Note into Common Stock, the Holder shall give notice of such election by delivering an executed and completed notice of conversion (“Notice of Conversion”) to the Borrower and such Notice of Conversion shall provide a breakdown in reasonable detail of the Principal Amount, accrued interest and fees being converted. On each Conversion Date (as hereinafter defined) and in accordance with its Notice of Conversion, the Holder shall make the appropriate reduction to the Principal Amount, accrued interest and fees as entered in its records and shall provide written notice thereof to the Borrower within two (2) business days after the Conversion Date. Each date on which a Notice of Conversion is delivered or telecopied to the Borrower in accordance with the provisions hereof shall be deemed a Conversion Date (the “Conversion Date”). A form of Notice of Conversion to be employed by the Holder is annexed hereto as Exhibit A.

(b) Pursuant to the terms of the Notice of Conversion, the Borrower will issue instructions to the transfer agent accompanied by an opinion of counsel within one (1) business day of the date of the delivery to Borrower of the Notice of Conversion and shall cause the transfer agent to transmit the certificates representing the Conversion Shares to the Holder by crediting the account of the Holder’s designated broker with the Depository Trust Corporation (“DTC”) through its Deposit Withdrawal Agent Commission (“DWAC”) system within three (3) business days after receipt by the Borrower of the Notice of Conversion (the “Delivery Date”). In the case of the exercise of the conversion rights set forth herein the conversion privilege shall be deemed to have been exercised and the Conversion Shares issuable upon such conversion shall be deemed to have been issued upon the date of receipt by the Borrower of the Notice of Conversion. The Holder shall be treated for all purposes as the record holder of such Common Stock, unless the Holder provides the Borrower written instructions to the contrary.

3.4 Conversion Mechanics.

(a) The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by dividing that portion of the principal and interest and fees to be converted, if any, by the then applicable Fixed Conversion Price. In the event of any conversions of outstanding principal amount under this Note in part pursuant to this Article III, such conversions shall be deemed to constitute conversions of outstanding principal amount applying to Monthly Amounts for the remaining Repayment Dates in chronological order. By way of example, if the original principal amount of this Note is $1,500,000 and the Holder converted $100,000 of such original principal amount prior to the first Repayment Date, then (1) the principal amount of the Monthly Amount due on the first Repayment Date would equal $0, (2) the principal amount of the Monthly Amount due on the second Repayment Date would equal $0 and (3) the principal amount of the Monthly Amount due on the third Repayment Dates would be $50,000.00.

(b) The Fixed Conversion Price and number and kind of shares or other securities to be issued upon conversion is subject to adjustment from time to time upon the occurrence of certain events, as follows:

A. Stock Splits, Combinations and Dividends. If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, or if a dividend is paid on the Common Stock in shares of Common Stock, the Fixed Conversion Price or the Conversion Price, as the case may be, shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such event.

B. Borrower Covenants. During the period the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the full conversion of this Note. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. The Borrower agrees that its issuance of this Note shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note.

C. Share Issuances. Subject to the provisions of this Section 3.4, if the Borrower shall at any time prior to the conversion or repayment in full of the Principal Amount issue any shares of Common Stock or securities convertible into Common Stock to a person other than the Holder (except (i) pursuant to Subsections A or B above; (ii) pursuant to currently outstanding options, warrants, or other rights to acquire the Common Stock of the Borrower outstanding on the date hereof as disclosed in the Borrower’s Securities Exchange Act of 1934 filings or as disclosed to to Holder in writing; or (iii) pursuant to securities that may be issued under any employee stock option and/or any stock plan adopted by the Borrower) (iv) pursuant to stock options and/or stock granted under the Borrower’s stock option plan for Borrower’s officers, directors, employees and advisors pursuant to arrangements, plans or contracts approved by the Borrower’s board of directors; (v) upon conversion of any preferred stock of the Borrower outstanding on the date hereof, or (vi) in connection with acquisition transactions approved by the Borrower’s board of directors provided, however, that the aggregate consideration for any individual acquisition f shall not exceed $2,500,000 in the aggregate, without the prior written consent of Laurus, which consent shall not be unreasonably withheld) for a consideration per share (the “Offer Price”) less than the Fixed Conversion Price in effect at the time of such issuance, then the Fixed Conversion Price shall be immediately reset to such lower Offer Price. For purposes hereof, the issuance of any security of the Borrower convertible into or exercisable or exchangeable for Common Stock shall result in an adjustment to the Fixed Conversion Price at the time of issuance of such securities.

D. Reclassification, etc. If the Borrower at any time shall, by reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes, this Note, as to the unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change.

3.5 Issuance of New Note. Upon any partial conversion of this Note, a new Note containing the same date and provisions of this Note shall, at the request of the Holder, be issued by the Borrower to the Holder for the principal balance of this Note and interest which shall not have been converted or paid. The Borrower will pay no costs, fees or any other consideration to the Holder for the production and issuance of a new Note.

ARTICLE IV
EVENTS OF DEFAULT

Upon the occurrence and continuance of an Event of Default beyond any applicable grace period, the Holder may make all sums of principal, interest and other fees then remaining unpaid hereon and all other amounts payable hereunder immediately due and payable. In the event of such an acceleration, within five (5) days after written notice from Holder to Borrower (each occurrence being a “Default Notice Period”) the amount due and owing to the Holder shall be 130% of the outstanding principal amount of the Note (plus accrued and unpaid interest and fees, if any) (the “Default Payment”). If, with respect to any Event of Default, the Borrower cures the Event of Default, the Event of Default will be deemed to no longer exist and any rights and remedies of Holder pertaining to such Event of Default will be of no further force or effect.
