               WHEREAS, Agent is in the business of providing marketing services and purchasing production;

               WHEREAS, Company desires to enter into this Agreement to procure Marketing Services from Agent;

               NOW, THEREFORE, for and in consideration of the mutual covenants and agreements set out in this Agreement, the Parties hereby agree as follows:

               1.        Scope of Marketing Services .

Agent shall provide certain advice and services to Company (the " Marketing Services "). The Marketing Services are to be performed in the capacity of an independent contractor in connection with certain aspects of the Company's business. Agent shall advise and consult with Company from time to time as reasonably requested by Company in connection with the marketing and sale of Company's production. Agent shall perform the Marketing Services in a diligent manner, with the level of care and skill exercised by a reasonable, prudent professional agent engaged in the same profession and under similar circumstances, and in accordance with sound and generally accepted industry standards. Agent shall devote such time to the performance of the Marketing Services as is necessary to effectively carry out the Marketing Services. Agent shall adhere to best reasonable schedules established by the Parties for the completion of Marketing Services; however, Agent will not be deemed in breach of this Agreement should such schedules not be met due to events or circumstances beyond the control of Agent. The Marketing Services to be provided by Agent to Company shall include, but not be limited to, the following:

               (a)        Gas Marketing Information . Agent shall gather detailed information regarding the gas marketing conditions and outlook for Company's Buena Vista prospect acreage. Such information shall include conditions for both the residue natural gas and the natural gas liquids, if present, as well as the availability of treating facilities.

               (b)        Downstream Options . Agent shall identify and evaluate all available "downstream" options; such evaluation shall include information such as distance, tap cost(s), existing line pressure(s), gas quality specifications, viability of take-away capacity and anticipated net values for Company's natural gas and products (NGLs (hereinafter defined) and crude/condensate, if present).

               (c)        Midstream/Gathering and Downstream Installation Options . Agent shall work with Company on all aspects of the installation of midstream/gathering and downstream facilities including reviewing and negotiating all contracts.

               (d)        Proper Procedures Regarding Downstream Transmission Pipeline(s) . Agent shall conduct operations with Company to facilitate the proper procedures with the downstream transmission pipeline(s) to ensure the downstream transmission pipeline(s) completes the installation of tap and measurement facilities to receive Company's residue natural gas. However, in the event a midstream/gathering provider installs the tap and measurement facilities, Agent will work with midstream/gathering provider and Company to ensure the tap and measurement facilities are designed to serve the best interest of Company.

               (e)        Cost Benefit Analysis . Agent will provide Company with a cost benefit analysis to determine the best marketing arrangement for Company's residue gas. Using Agent's knowledge and expertise, Agent shall provide Company with the marketing arrangements that, in Agent's opinion, shall yield the highest netback value to Company.

               (f)        Pricing Strategies . Agent shall provide Company with comprehensive pricing strategies such as first of the month pricing, daily pricing, and fixed pricing. Agent will also offer risk management, structured products, and portfolio pricing.

               (g)        Possible Purchasers . Once the Parties have both executed the GPA, Agent shall disclose, to Company, all valid bids received for Company's production. Such disclosure shall fully detail the spectrum of all purchasers including a detailed description of each purchaser's offer to purchase Company's production. Agent shall provide Company with all necessary supporting documentation and pricing components to enable Company to verify proper pricing.

               (h)        Natural Gas Liquids .        If Natural Gas Liquids (" NGLs ") are present, Agent shall make recommendations regarding the best marketing options for Company's NGLs. Agent shall fully disclose available purchasers for Company's NGLs in the Buena Vista prospect acreage to Company; the disclosure shall include all documentation necessary to prove up the Agent's recommendation regarding the best marketing option for Company.

               2.        Independent Contractor .

It is expressly understood that Agent is an independent contractor and that Agent, Agent's partners, affiliates, employees, and subcontractors, if any, are not employees of Company. Agent will be responsible for determining his own work schedule; provided , however , Agent agrees to perform the Marketing Services required hereunder in such a manner as to allow Agent to meet any reasonable time deadlines required by Company. Agent shall be responsible for the supervision and control of Agent's employees, contractors and subcontractors, if any, and for determining the manner in which the Marketing Services are performed Agent shall furnish, at its own expense, all necessary machinery, computers, software, equipment, tools, transportation and whatever else is necessary in the performance of the Marketing Services. Neither Party has any authority to legally bind the other Party in any respect.

               3.        Term .

This Agreement shall be deemed to have commenced on the Effective Date and shall continue for the latter of a period of one (1) year (the " Term "), or until Company produces its first production, at which time the Parties will have entered into a GPA, unless sooner terminated pursuant to the provisions of this Agreement.

               4.        Expenses and Payment .

Agent shall bear and pay all expenses related to the performance of the Marketing Services. Company shall in no situation owe any compensation to Agent for Marketing Services performed or to be performed.

Agent acknowledges that all such Confidential Information belongs to Company, constitutes specialized and highly Confidential Information not generally known in the industry; and, in some instances, constitutes trade secrets of Company. Accordingly, Agent recognizes and acknowledges that it is essential to Company to protect Company's Confidential and proprietary Information and Agent agrees to hold such Confidential Information in trust and confidence for Company's sole and exclusive use and benefit. During the Term of this Agreement and for a period of two (2) years thereafter, Agent shall not disclose any Confidential Information to any person, firm or association or other entity for any reason or purpose whatsoever, unless such Confidential Information has already become known to the general public or unless Agent is required to disclose the Confidential Information by a court of competent jurisdiction. In the event Agent is requested or required by judicial or administrative process to disclose such Confidential Information, Agent agrees to promptly notify Company of the request or requirement for disclosure, and to cooperate with Company should it seek an appropriate protective order or other appropriate remedy, and disclose only that portion of the Confidential Information that Agent is ordered to disclose or that Company agrees to allow to be disclosed.
