This Note has been entered into pursuant to the terms of a subscription agreement between the Borrower and the Holder dated at or about the date hereof (the “Subscription Agreement”), and shall be governed by the terms of such Subscription Agreement. Unless otherwise separately defined herein, all capitalized terms used in this Note shall have the same meaning as is set forth in the Subscription Agreement. The following terms shall apply to this Note:

ARTICLE I

ARTICLE II

CONVERSION RIGHTS

The Holder shall have the right to convert the principal due under this Note into Shares of the Borrower’s Common Stock, $.0001 par value per share (“Common Stock”) as set forth below.

2.1. Conversion into the Borrower’s Common Stock.

(a) The Holder 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 at the election of the Holder (the date of giving of such notice of conversion being a “Conversion Date”) into fully paid and nonassessable shares of Common Stock as such stock exists on the date of issuance of this Note, or any shares of capital stock of Borrower into which such Common Stock shall hereafter be changed or reclassified, at the conversion price as defined in Section 2.1(b) hereof (the “Fixed Conversion Price”), determined as provided herein. Upon delivery to the Borrower of a completed Notice of Conversion, a form of which is annexed hereto as Exhibit A, Borrower shall issue and deliver to the Holder within three (3) business days after the Conversion Date (such third day being the “Delivery Date”) that number of shares of Common Stock for the portion of the Note converted in accordance with the foregoing. At the election of the Holder, the Borrower will deliver accrued but unpaid interest on the Note, if any, through the Conversion Date directly to the Holder on or before the Delivery Date. 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 interest, if any, to be converted, by the Conversion Price.

(b) Subject to adjustment as provided in Section 2.1(c) hereof, the fixed conversion price per share shall be equal to $1.54 (“Fixed Conversion Price”).

(c) The Fixed Conversion Price and number and kind of shares or other securities to be issued upon conversion determined pursuant to Section 2.1(a), shall be subject to adjustment from time to time upon the happening of certain events while this conversion right remains outstanding, as follows:

A. Merger, Sale of Assets, etc. If (A) the Borrower effects any merger or consolidation of the Borrower with or into another entity, (B) the Borrower effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by the Borrower or another entity) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, (D) the Borrower consummates a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with one or more persons or entities whereby such other persons or entities acquire more than the 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by such other persons or entities making or party to, or associated or affiliated with the other persons or entities making or party to, such stock purchase agreement or other business combination), (E) any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the 1934 Act) is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the 1934 Act), directly or indirectly, of 50% of the aggregate Common Stock of the Borrower, or (F) the Borrower effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a “Fundamental Transaction”), this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to convert into such number and kind of shares or other securities and property as would have been issuable or distributable on account of such Fundamental Transaction, upon or with respect to the securities subject to the conversion right immediately prior to such Fundamental Transaction. The foregoing provision shall similarly apply to successive Fundamental Transactions of a similar nature by any such successor or purchaser. Without limiting the generality of the foregoing, the anti-dilution provisions of this Section shall apply to such securities of such successor or purchaser after any such Fundamental Transaction.

B. 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 that may be issued or outstanding, this Note, as to the unpaid principal portion thereof, 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.

C. 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 Conversion Price 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.

(d) Whenever the Conversion Price is adjusted pursuant to Section 2.1(c) above, the Borrower shall promptly mail to the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a statement of the facts requiring such adjustment.

(e) During the period the conversion right exists, Borrower will reserve from its authorized and unissued Common Stock not less than an amount of Common Stock equal to 150% of the amount of shares of Common Stock issuable upon the full conversion of this Note. Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. 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.

2.2 Method of Conversion. This Note may be converted by the Holder in whole or in part as described in Section 2.1(a) hereof and the Subscription Agreement. Upon 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.

2.3. Maximum Conversion. The Holder shall not be entitled to convert on a Conversion Date that amount of the Note in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates on a Conversion Date, (ii) any Common Stock issuable in connection with the unconverted portion of the Note, and (iii) the number of shares of Common Stock issuable upon the conversion of the Note with respect to which the determination of this provision is being made on a Conversion Date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Borrower on such Conversion Date. For the purposes of the provision to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder shall not be limited to aggregate conversions of 4.99%. The Holder shall have the authority and obligation to determine whether the restriction contained in this Section 2.3 will limit any conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Notes are convertible shall be the responsibility and obligation of the Holder. The Holder may waive the conversion limitation described in this Section 2.3, in whole or in part, upon and effective after 61 days prior written notice to the Borrower to increase such percentage to up to 9.99%. Notwithstanding anything to the contrary herein, Holder agrees that the aggregate number of shares of Common Stock issuable upon any and all exercises of this Note are subject to the Numeric Limitation (as defined in the Subscription Agreement).

ARTICLE III

SECURITY INTEREST

4. Security Interest/Waiver of Automatic Stay. This Note is secured by a security interest granted to the Holder pursuant to a Security Agreement and Guaranty, as delivered by Borrower to Holder. The Borrower acknowledges and agrees that should a proceeding under any bankruptcy or insolvency law be commenced by or against the Borrower, or if any of the Collateral (as defined in the Security Agreement) should become the subject of any bankruptcy or insolvency proceeding, then the Holder should be entitled to, among other relief to which the Holder may be entitled under the Transaction Documents and any other agreement to which the Borrower and Holder are parties (collectively, “Loan Documents”) and/or applicable law, an order from the court granting immediate relief from the automatic stay pursuant to 11 U.S.C.
