INC., a Colorado corporation (hereinafter, the “Stratex”).



WHEREAS, Eagleford,
Zavala and Stratex are parties to a Joint Development Agreement dated as of December 3, 2013 (the “Development Agreement”),

WHEREAS, Eagleford,
Zavala and Stratex desire to amend the Development Agreement in several respects.



NOW THEREFORE,
for and in consideration of the mutual promises contained in the Development Agreement, the benefits to be derived by each party

the parties hereto agree as follows:



| | 1. | Amendments. Upon the execution hereof, the Development Agreement is amended as follows:
| | -- | ---------------------------------------------------------------------------------------



| | (a) | Section 2 of the Development Agreement is hereby deleted in its entirety and the following shall
be substituted therefor:

“2. Performance of
Initial Operation. As soon as practicable, but in no event later than March 31, 2014, Stratex shall complete or cause to be
completed, either (i) the hydraulic fracturing of the Matthews #1H well (the “1H Completion”) or (ii) the spudding
of a new well with a targeted depth in a formation capable of producing hydrocarbons (the “Spudding”). Either
the timely commencement of the 1H Completion or the Spudding shall hereinafter be referred to as the “Initial Operation”.
In the case of the 1H Completion, Stratex shall be responsible for all costs associated with the 1H Completion from this date forward
including, but not limited to, any payments required to be made to the lessors pursuant to Paragraphs 2.B(2), 2.C and 2.D of the
Matthews Lease. In exchange for this commitment, Stratex is hereby granted an undivided working interest with respect to the Matthews
#1H well equal to (i) two-thirds (66.67%) of 8/8ths of all the oil, gas and other minerals which may be produced and sold therefrom
until Payout (as hereinafter defined) and (ii) one-half (50%) of 8/8ths of all the oil, gas and other minerals which may be produced
and sold therefrom after Payout. Solely for purposes of this Section 2, Payout shall mean the point in time when Stratex shall
have recouped from the proceeds of oil and gas production from such Matthews #1H Well, after deducting (a) severance, production,
windfall profit and other taxes payable on such share of production, and (b) lessor's royalties, overriding royalties (including
any overriding royalty interests) and like burdens which the Matthews Lease is burdened as of the date hereof, an amount equal
to the aggregate of all costs incurred by Stratex in performing the 1H Completion.”



| | (b) | Section 3 of the Development Agreement is hereby deleted in its entirety and the following shall
be substituted therefor:
| | --- | -------------------------------------------------------------------------------------------------------------------------



“3. Grant of Working
Interest and Exclusive Development Rights. Following payment by Stratex of all consideration set forth in Section 4 below,
Stratex shall have earned and be entitled to receive, an assignment of an undivided working interest in the Development Acreage
equal to fifty percent (50%) of 8/8ths of all the oil, gas and other minerals which may be produced and sold from the lands comprised
therein. Immediately following the payment of all such consideration (time being of the essence), Zavala shall execute and deliver
to Stratex, an assignment of working interest in the form attached hereto as Exhibit A, which shall be in recordable form for filing
in Zavala County.
