(a)          At any time after February 9, 2013, the Principal Amount and all accrued unpaid interest thereon (the “Conversion Amount”) shall be convertible (in whole or in part), at the option of the Investor (the “Conversion”), into such number of duly authorized, validly issued fully paid and non-assessable shares of Common Stock of the Guarantor (the “Conversion Shares”) as is determined by dividing (x) an amount equal to that portion of Conversion Amount that the Investor elects to convert by (y) $9.00 (the “Conversion Price”). The Investor shall deliver to the Guarantor a written notice of conversion (the “Conversion Notice”), in the form attached hereto as Exhibit B, stating the portion of the Conversion Amount to be converted and the date of such Conversion (the “Conversion Date”), which shall be no earlier than the 15^th Business Day following the date on which the Guarantor receives the Conversion Notice. With respect to partial conversions of the Conversion Amount, the Investor and the Guarantor shall keep written records of the amount of the Conversion Amount converted on of each Conversion Date.

Such certificate or certificates representing the shares of Common Stock being acquired upon the related conversion will bear a restrictive legend as set forth in Section 3.7(d) herein. If in the case of any Conversion Notice such certificate or certificates are not delivered to or as directed by the Investor by the Delivery Date, the Investor shall be entitled by written notice to the Guarantor at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, whereupon the Company and the Investor shall each be restored to their respective positions immediately prior to the delivery of such notice of revocation.

(c)          Acknowledgment of Registration. The Investor acknowledges that the Note and any shares of the Guarantor issued upon conversion of the Note are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law.

(d)          Adjustments. The Conversion Price and number of Conversion Shares issuable upon conversion of this Note are subject to adjustment from time to time as set forth below.

(i)          Stock Dividends and Splits. If the Guarantor, at any time on or after the date hereof, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event.  Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately to reflect such event.

(ii)         Number of Conversion Shares. Simultaneously with any adjustment to the Conversion Price pursuant to paragraph (i) of this Section 1.7(d), the number of Conversion Shares that may be purchased upon exercise of this Note shall be increased or decreased proportionately, so that after such adjustment the aggregate Conversion Price payable hereunder for the adjusted number of Conversion Shares shall be the same as the aggregate Conversion Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

(iii)        Reorganization and Reclassification; Merger or Asset Sale. In the event the Guarantor shall at any time or from time to time (i) effect a reorganization, (ii) consolidate with or merge into any other person (other than a merger or reorganization involving only a change in the state of incorporation of the Guarantor), or (iii) transfer all or substantially all of its properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Guarantor, then, in each such case, the Investor of any Note shall thereafter be entitled to purchase pursuant to such Note (in lieu of the number of Conversion Shares which such Investor would have been entitled to acquire immediately prior to such reorganization or reclassification, consolidation, merger or asset sale or on the effective date of such dissolution) the shares of stock of any class or classes or other securities or property to which the holder of such number of shares of Common Stock would have been entitled at the time of such reorganization or reclassification, at an aggregate Conversion Price equal to that which would have been payable if such number of shares of Common Stock had been purchased immediately prior to such reorganization or reclassification, consolidation, merger, asset sale or dissolution, and appropriate provision (as determined by resolution of the Board of Directors of the Guarantor with the approval of the Investor) shall be made with respect to the rights and interest thereafter of the Note (including adjustment provisions) shall thereafter be applicable, as nearly as reasonably practicable, in relation to such stock or other securities or property.

(iv)         Calculations. All calculations under this Section 1.7(d) shall be made by rounding to the nearest cent or the nearest 1/100th of a share, as applicable.

(e)          Effect of Conversion. Upon full conversion of this Note, the Company and Guarantor will be forever released from all of its obligations and liabilities under this Note, other than its obligation to deliver Conversion Shares as provided herein.

Section 1.8           Mandatory Prepayments. Promptly, but in any event not more than two (2) Business Days after the receipt by the Company of any cash proceeds of any sale, assignment, lease, license, transfer or other disposition of any or all of the Oil and Gas Properties, the Company shall prepay the Note in an aggregate amount equal to such cash proceeds, after deducting therefrom any attorneys’ fees, accountants’ fees, investment banking fees and other customary fees and expenses, in each case incurred in connection with such sale, assignment, lease, license, transfer or other disposition, and amounts required to be applied to the repayment of Indebtedness with respect to such Oil and Gas Properties expressly permitted under the Purchase Agreement; provided, however, that, if an Event of Default does not exist at the time of the receipt of such cash proceeds, such cash proceeds shall not be required to be so applied to the extent that the Company has delivered an officer’s certificate to the Investor promptly following the receipt of such cash proceeds stating that such cash proceeds shall be used to fund the acquisition of other oil and gas properties or other property used or usable in the business of the Company within 180 days following the date of the receipt of such cash proceeds.  Any such oil and gas properties or other property so acquired shall become part of the Collateral and the Company shall execute and deliver to the Investor such agreements, documents and instruments in connection therewith as the Investor may reasonably request. If all or any portion of such cash proceeds are not so used within 180 days after the date of the receipt of such cash proceeds, such remaining portion shall be applied in accordance with the Purchase Agreement and this Note on the first Business Day of the next calendar month immediately following such 180^th day.
