6. Conversion Rights. Purchaser shall have the right to convert this Note and accrued and unpaid Interest due under this Note into shares of Common Stock, as set forth below.

(a) Conversion into Issuer’s Common Stock. Purchaser shall have the right from and after the date of the issuance of this Note and then at any time until this Note is fully paid, to convert any outstanding and unpaid principal portion of this Note, and accrued Interest on such portion, at the election of the Purchaser (the date of such conversion being a “Conversion Date”) into fully paid and non-assessable shares of Common Stock as such stock exists on the date of issuance of this Note, or any shares of capital stock of the Company into which such Common Stock shall hereafter be changed or reclassified, at the conversion price of $0.25 (the “Conversion Price”). Upon delivery to the Issuers of a completed Notice of Conversion, a form of which is attached hereto, the Issuers shall issue and deliver to the Purchaser within five (5) business days from the Conversion Date (such day being the “Delivery Date”) that number of shares for the portion of the Note and related accrued Interest converted in accordance with the foregoing. 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 of the Note and accrued Interest to be converted, by the Conversion Price.

5

(b) Manner of Conversion.

(i) Surrender of the Note. This Note may be converted by Purchaser by presentment of this Note, accompanied by written notice stating that Purchaser elects to convert all or a portion of the principal amount thereof and stating the name or names, together with addresses, in which the Conversion Shares are to be issued. A minimum of at least Fifty Thousand Dollars ($50,000) of the principal amount must be tendered in each conversion (if any), unless the aggregate principal amount outstanding under this Note is less than $50,000. Each conversion shall be deemed to have been effected immediately prior to the close of business on the date on which this Note shall have been so surrendered to Issuer; and at such time the rights of the Purchaser as to that portion of this Note so converted shall cease, and the person in whose name or names any certificate or certificates for Conversion Shares (or other securities) shall be issuable upon such conversion shall be deemed to have become the holder or holders of record thereof. If this Note is converted in part only, upon conversion of such part hereof, Issuer shall execute and deliver to the Purchaser upon surrender of this Note a new Note in the aggregate principal amount equal to the then unconverted portion of the principal amount of this Note and in all other respects identical to this Note.

(ii) Accrued Interest, Etc. Issuer will pay to Purchaser converting this Note any accrued but unpaid Interest on the principal amount so converted up to and including the Conversion Date.

(c) Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time as follows:

(i) Dividends, Splits, Combinations, Reclassifications. In the event Issuer shall hereafter (i) pay a stock dividend or make a stock distribution of shares of Common Stock with respect to the Common Stock, (ii) subdivide its outstanding Common Stock into a greater amount of Common Stock, (iii) combine its outstanding Common Stock into a smaller amount of Common Stock, or (iv) issue by reclassification of its Common Stock any other security of Issuer, the Conversion Price in effect immediately prior to such action shall be adjusted so that Purchaser shall be entitled to receive the amount of Common Stock or other capital stock of Issuer it would have owned immediately following such action had this Note or any remaining portion hereof been converted in full immediately prior thereto. All adjustments made pursuant to this subsection 6(c)(i) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. If, as a result of an adjustment made pursuant to this subsection 6(c)(i), Purchaser shall become entitled to receive the Conversion Shares and other securities of Issuer, the Board of Directors of Issuer shall reasonably determine the allocation of the adjusted Conversion Price between or among the Conversion Shares and such other securities.

(ii) De Minimus Exception. If the amount of any single adjustment of the Conversion Price required pursuant to subsection 6(c) would be less than one cent ($.01) at the time

6

such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate at least one cent ($.01) when the Conversion Price is subsequently adjusted.

(d) Sale of Shares of Common Stock Below Conversion Price.

(i) If at any time or from time to time after the date this Note is issued, Issuer issues or sells, or is deemed by the express provisions of this Section 6(d) to have issued or sold, Additional Shares of Common Stock (as hereinafter defined), other than as a dividend or other distribution on any class of stock as provided in Section 6(c)(i) above, and other than a subdivision or combination of shares of Common Stock as provided in Section 6(c)(i) above, for an Effective Price (as hereinafter defined) less than the Conversion Price (subject to adjustment for any events after the Issue Date described in Section 6(c)(i), then the then existing Conversion Price shall be reduced, as of the opening of business on the date of such issue or sale, to a price equal to the Effective Price.

(ii) Determination of Consideration. For the purpose of making any adjustment required under this Section 6(d), the consideration received by Issuer for any issue or sale of securities shall (A) to the extent it consists of cash, be the amount of cash received by Issuer therefor before deducting any discounts, commissions or other expenses allowed, paid or incurred by Issuer for any underwriting or otherwise in connection thereof, (B) to the extent it consists of property other than cash, be computed at the fair value of that property as determined in good faith by the Board of Directors, and (C) if Additional Shares of Common Stock, Convertible Securities (as hereinafter defined) or rights or options to purchase either Additional Shares of Common Stock or Convertible Securities are issued or sold together with other stock or securities or other assets of Issuer for a consideration which covers both, be computed as the portion of the consideration so received that may be reasonably determined in good faith by the Board of Directors to be allocable to such Additional Shares of Common Stock, Convertible Securities or rights or options.

(iii) Treatment of Convertible Securities. For the purpose of the adjustment required under this Section 6(d), if Issuer issues or sells any rights or options for the purchase of, or stock or other securities convertible into, Additional Shares of Common Stock (such convertible stock or securities being herein referred to as “Convertible Securities”) and if the Effective Price of such Additional Shares of Common Stock is less than the Conversion Price (subject to adjustment as aforesaid), in each case Issuer shall be deemed to have issued at the time of the issuance of such rights or options or Convertible Securities the maximum number of Additional Shares of Common Stock issuable upon exercise or conversion thereof and to have received as consideration for the issuance of such shares an amount equal to the total amount of the consideration, if any, received by Issuer for the issuance of such rights or options or Convertible Securities, plus, in the case of such rights or options, the amounts of consideration, if any, payable to Issuer upon the exercise of such rights or options, plus, in the case of Convertible Securities, the amounts of consideration, if any, payable to Issuer (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) upon the conversion thereof; provided that if, in the case of Convertible Securities, the amounts of such consideration cannot be ascertained but are

7

a function of anti-dilution or similar protective clauses, Issuer shall be deemed to have received the amounts of consideration without reference to such clauses; and provided further that if the amount of consideration payable to Issuer upon the exercise or conversion of rights, options or Convertible Securities is reduced over time or on the occurrence or non-occurrence of specified events other than by reason of anti-dilution adjustments, the Effective Price shall be recalculated using the figure to which such amount of consideration is reduced; and provided further that if the amount of consideration payable to Issuer upon the exercise or conversion of such rights, options or Convertible Securities is subsequently increased, the Effective Price shall be again recalculated using the increased amount of consideration payable to Issuer upon the exercise or conversion of such rights, options or Convertible Securities. No further adjustment of the Conversion Price, as adjusted upon the issuance of such rights, options or Convertible Securities, shall be made as a result of the actual issuance of Additional Shares of Common Stock on the exercise of any such rights or options or the conversion of any such Convertible Securities. If any such rights or options or the conversion privilege represented by any such Convertible Securities shall expire without having been exercised, the Conversion Price as adjusted upon the issuance of such rights, options or Convertible Securities shall be readjusted to the Conversion Price which would have been in effect had an adjustment been made on the basis that the only Additional Shares of Common Stock so issued were the Additional Shares of Common Stock, if any, actually issued or sold on the exercise of such rights or options or rights of conversion of such Convertible Securities, and such Additional Shares of Common Stock, if any, were issued or sold for the consideration actually received by Issuer upon such exercise, plus the consideration, if any, actually received by Issuer for the granting of all such rights or options, whether or not exercised, plus the consideration received for issuing or selling the Convertible Securities actually converted, plus the consideration, if any, actually received by Issuer (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion of such Convertible Securities, provided that such readjustment shall not apply to prior conversions of this Note.

(iv) Excluded Issuances. For purposes of this Note, the term “Additional Shares of Common Stock” shall mean all shares of Common Stock issued by Issuer or deemed to be issued pursuant to this Section 6(d), whether or not subsequently reacquired or retired by Issuer other than (i) shares of Common Stock issued upon conversion of this Note; and (ii) the issuance of the Option and Warrant Shares (as defined in the Note Purchase Agreement).

(v) Effective Price. For purposes of this Note, the term “Effective Price” of Additional Shares of Common Stock shall mean the quotient determined by dividing the total number of Additional Shares of Common Stock issued or sold, or deemed to have been issued or sold by Issuer under this Section 6(d), into the aggregate consideration received, or deemed to have been received by Issuers for such issue under this Section 6(d), for such Additional Shares of Common Stock.

7. No Right of Redemption. This Note may not be redeemed or paid without the prior written consent of Purchaser; provided, however, that in the event of redemption, the price shall be the principal amount redeemed plus accrued Interest.
