STW RESOURCES HOLDING CORP.

FORM OF 12% CONVERTIBLE NOTE

FOR VALUE RECEIVED, STW RESOURCES HOLDING CORP., a Nevada corporation (the “Company”), hereby promises to pay to the order of _______________________, or its assigns (the “Holder”), without demand, the sum of ______________ Dollars ($_________), with interest accruing at the rate described below.

This Note has been entered into pursuant to the terms of a Subscription Agreement among the Company and the holders of the Company Notes (as defined below), dated _____ __, 2010 (the “Agreement”), and shall be governed by the terms of such Agreement. Unless otherwise separately defined herein, all capitalized terms used in this Note shall have the same meaning as is set forth in the Agreement which together with the Note, will be referred to as the “Transaction Documents”).

ARTICLE I

GENERAL PROVISIONS

1.1 Payments. Interest payable on this Note shall accrue from the Issue Date indicated above at a rate per annum (the “Interest Rate”) equal to twelve percent (12%), subject to adjustment pursuant to Section 1.2 (the “Interest”). Interest shall be computed for actual days elapsed on the basis of a 360 day year consisting of twelve 30-day months. The principal of this Note (the “Principal”) and accrued but unpaid Interest thereon shall, unless earlier converted, be payable in full on the date that shall be twelve (12) months after the Issue Date (the “Maturity Date”).

Upon any conversion in part by the Holder in accordance with Article II, the Holder and the Company shall in good faith recalculate the outstanding Principal and the accrued but unpaid Interest payable with respect to the converted portion. Upon any full conversion by the Holder in accordance with Article II, all of the payments of Principal due hereunder shall terminate and no further due but unpaid Interest shall accrue. All payments shall be applied first to Interest that has become due pursuant to this Note and remains unpaid and then to the outstanding Principal of this Note.

1.2 Default Interest. Upon the occurrence of an Event of Default (as defined below), the unpaid Principal on this Note shall bear interest at the rate of fifteen percent (15%) per annum (the “Default Rate”) until such amount is paid in full. Nothing contained herein or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law.

1.3 Conversion Rights. The conversion rights set forth in Article II shall remain in full force and effect immediately from the date hereof and until the Note is paid in full regardless of the occurrence of an Event of Default. The Note shall be payable in full on the Maturity Date, except to the extent previously converted into Common Stock of the Company (the “Common Stock”) in accordance with Article II hereof.

1.4 Prepayment Option. The Company may prepay in cash all or any portion of the outstanding principal amount of this Note, without penalty, on the 30th day following written notice to the Holder (the “Redemption Date”). The Holder shall have the right to convert any outstanding principal or interest in accordance with Article II hereof up until the Redemption Date. If the Company elects to redeem the Notes and the Notes are not converted prior to the Redemption Date, the Company will be required to pay all remaining interest payable on the Notes had the Notes remained outstanding until the Maturity Date.

ARTICLE II

CONVERSION RIGHTS

The Holder shall have the right to convert the Principal and accrued and unpaid Interest due under this Note into shares of the Company’s Common Stock, as set forth below.

2.1 Conversion into the Company’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, and accrued Interest on such portion, at the election of the Holder (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 this Note (such shares, the “Conversion Shares”), or any shares of capital stock of the Company into which such Common Stock shall hereafter be changed or reclassified, at the conversion price as defined in Section 2.1(b) hereof (the “Conversion Price”), determined as provided herein. Upon delivery to the Company of a completed Notice of Conversion, a form of which is annexed hereto, Company shall issue and deliver to the Holder within three (3) business days from the Conversion Date (such third day being the “Delivery Date”) that number of Conversion Shares for the portion of the Principal, along with accrued but unpaid 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. No fractional shares shall be issued for any payment of Interest due under this Note. As to any fraction of a share which Holder would otherwise be entitled to upon such payment of Interest, the Company shall round up to the next whole share. Each conversion hereof shall constitute the re-affirmation by the Holder that the representations and warranties contained in the Subscription Agreement are true and correct in all material respects with respect to the Holder as of the time of such conversion. 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 Company to the Holder for the remaining Principal balance of this Note and Interest which shall not have been paid.

(b) Subject to adjustment as provided in Section 2.1(c) hereof, the Conversion Price per share shall be equal to $0.25.

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

(i) Reorganization, Consolidation, Merger, etc.; Reclassification. In case at any time or from time to time, the Company shall effect any merger, reorganization, restructuring, reverse stock split, consolidation, sale of all or substantially all of the Company’s assets or any similar transaction or related transactions (each such transaction, a “Fundamental Change”), then, in each such case, as a condition to the consummation of such a transaction, proper and adequate provision shall be made by the Company whereby the Holder of this Note, on the conversion hereof, at any time after the consummation of such Fundamental Change, shall receive, in lieu of the Conversion Shares issuable on such conversion prior to such consummation or such effective date, the stock and other securities and property (including cash) to which such Holder would have been entitled upon such consummation of a Fundamental Change if such Holder had so converted this Note, immediately prior thereto, all subject to further adjustment thereafter as provided in Section 2.1(c)(iv).

If the Company 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 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.

(ii) Dissolution. In the event of any dissolution of the Company following the transfer of all or substantially all of its properties or assets, the Company, prior to such dissolution, shall at its expense deliver or cause to be delivered the stock and other securities and property (including cash, where applicable) receivable by the Holder of this Note after the effective date of such dissolution pursuant to this Article to a bank or trust company (a “Trustee”) as trustee for the Holder of this Note.

(iii) Continuation of Terms. Upon any Fundamental Change or transfer (and any dissolution following any transfer) referred to in this Article, this Note shall continue in full force and effect and the terms hereof shall be applicable to any other securities and property receivable on the conversion of this Note after the consummation of such Fundamental Change or transfer or the effective date of dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any other securities, including, in the case of any such transfer, the person acquiring all or substantially all of the properties or assets of the Company, whether or not such person shall have expressly assumed the terms of this Note as provided in Section 2.1(c)(iv). In the event this Note does not continue in full force and effect after the consummation of the transaction described in this Article II, then only in such event will the Company’s securities and property (including cash, where applicable) receivable by the Holder of the Notes be delivered to the Trustee as contemplated by Section 2.1(c)(ii).

(iv) Extraordinary Events Regarding Common Stock. In the event that the Company shall (a) issue additional shares of Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the Conversion Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Conversion Price then in effect. The Conversion Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 2.1(c)(iv). The number of Conversion Shares that the Holder of this Note shall thereafter, on the conversion hereof as provided in Article II, be entitled to receive shall be adjusted to a number determined by multiplying the number of Conversion Shares that would otherwise (but for the provisions of this Section 2.1(c)(iv)) be issuable on such conversion by a fraction of which (a) the numerator is the Conversion Price that would otherwise (but for the provisions of this Section 2.1(c)(iv)) be in effect, and (b) the denominator is the Conversion Price in effect on the date of such conversion.

(v) Subsequent Equity Sales. If, at any time while this Note is outstanding, the Company sells or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share that is lower than the then Conversion Price (such lower price, the “Base Conversion Price” and such issuances, collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment in the Conversion Price shall be made for shares of Common Stock issued, or warrants or options to purchase shares Common Stock granted, in connection with any of the following: (a) shares or options pursuant to an employee benefit plan, approved by the Company’s board of directors, for directors, officers, employees, advisors or consultants of the Company, (b) full or partial consideration in connection with a strategic merger, consolidation or purchase of substantially all of the securities or assets of a corporation or other entity, (c) shares issued for commissions or other fees payable in connection with this Offering or any future offering of the Company’s securities, (d) securities upon the exercise or exchange of or conversion of any Securities issued hereunder and/or other securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding on the date of this Agreement, provided that such securities have not been amended since the date of this Agreement to increase the number of such securities or to decrease the exercise, exchange or conversion price of such securities or (e) securities issued in connection with a debt financing.

(vi) Effectiveness of Adjustment. An adjustment to the Conversion Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment.

(vii) Notice of Adjustment. Upon the happening of any event requiring an adjustment of the Conversion Price, the Company shall promptly give written notice thereof to the Holder at the address appearing in the records of the Company, stating the adjustments resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Holder or any defect therein shall not affect the legality or validity of the subject adjustment.

2.2 Reservation. During the period the conversion right exists, the Company shall reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of providing for the conversion of the Company Notes, such number of Conversion Shares as shall from time to time equal the number of shares sufficient to permit the conversion of the Company Notes in accordance with their respective terms. The Company agrees that all Conversion Shares issued upon due conversion of the Company Notes shall be, at the time of delivery of the certificates for such Conversion Shares, duly authorized, validly issued, fully paid and non-assessable shares of common stock of the Company.

2.3 Fractional Shares. No fractional shares shall be issued upon the conversion of this Note. As to any fraction of a share which Holder would otherwise be entitled to upon such conversion, the Company shall round up to the next whole share.

If, after such thirty (30) day period, the default has not been remedied or cured, then such default will give rise to an “Event of Default” under this Article III.

ARTICLE IV

MISCELLANEOUS

4.1 Failure or Indulgence Not Waiver. No failure or delay on the part of Holder hereof in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.
