Section 3. Designation of Areas of Mutual Interest. This Agreement establishes two types of areas of mutual interest (individually an “AMI” and collectively “AMI’s”) within the Exploration Area, and the Participants have further delineated them on the outlines and plats which are attached hereto, and in the aggregate constitute Exhibit “A” attached hereto. The categories of AMI’s that are shown are: (i) the current exterior boundaries of all the 3D Data surveys which Century’s Parent and/or Century have licensed under the Data Purchase Agreements and other data which Century has contributed pursuant to this Agreement, together with the exterior boundaries of any other 3D surveys under Data Purchase Agreements which the Participants may acquire during the Term (each a “3D AMI”); and (ii) an outline of each Prospect designated prior to or during the Term (each a “Prospect AMI”). If during the Term new areas outside of any particular AMI are to be explored within the Exploration Area by the Participants, a new 3D AMI or Prospect AMI shall be designated, as the case may be, to include these areas by amending Exhibit “A” to include such AMI’s. Exhibit “A” shall be a compilation of the various outlines and plats constituting the AMI’s designated from time to time hereunder as follows: Exhibit “A-1” shall contain the Exploration Area outline, Exhibit “A-2” shall contain 3D AMI outlines, and Exhibit “A-3” shall contain Prospect AMI plats. In regard to each 3D AMI, if any question arises as to the boundary of any individual seismic survey comprising that 3D AMI, the

survey plat for the seismic survey in question shall define that 3D AMI.

Upon termination of this Agreement (“Termination”), if either Participant acquires leases or other contractual interests within (i) eighteen (18) months after Termination in respect to any 3D AMI which is in existence prior to the Effective Date; (ii) the later of either four (4) years from the date that any 3D AMI is established after the Effective Date or eighteen (18) months after Termination or (iii) three (3) years after Termination in respect to any Prospect AMI, the acquiring Participant shall notify the non-acquiring Participant of the details of such acquisition and the non-acquiring Participant shall have thirty (30) days from receipt of such notice to acquire up to its Percentage Interest in the acquiring Participant’s interest in the leases or other contractual interests and participate in the development of the leases in accordance with the JOA (as hereinafter defined) or other form of operating agreement if a third party is the operator. If the non-acquiring Participant elects to acquire an interest, it shall reimburse acquiring Participant within thirty (30) days of receipt of such notice for the actual costs incurred by the acquiring Participant in respect to such acquisition, proportionately reduced to the percentage acquired. If Century owns at least a twenty-five percent (25%) interest in such leases, Century may elect to be operator pursuant to the JOA.

Section 4. Prospect Generation and Designation. TechXplore and Century dedicated personnel shall analyze, interpret and otherwise utilize the 3D Data provided by Century’s Parent and/or Century under the Data Purchase Agreements, as well as other geological information, to identify geologic leads and to generate Prospects within the 3D AMI’s. Following the generation of any Prospect, the Participants shall meet to review such Prospect. If the Participants agree that such Prospect merits drilling that Prospect shall be formally designated in writing as a Prospect, a Prospect AMI shall be created and agreed to by the Participants and same shall be depicted on an amended Exhibit “A-3”.

Section 5. Prospect Description. Each Prospect so designated shall be identified by a name and an information package containing the following information shall be assembled:

(a) a comprehensive sufficient legal description of the portion of the Exploration Area comprising the Prospect together with a plat thereof of sufficient detail so that a Prospect AMI can be defined and utilized for purposes of Exhibit “A-3”;

(b) the initial well location, the primary objective formation and any secondary formations, together with technical justification for the Prospect, containing merits and risks, with reasonable support data;

(c) a summary setting forth the commercial terms of conducting the Exploration Activities within the Prospect AMI, including without limitation (i) description of the leases covering the Prospect and all agreements pertaining thereto, (ii) the working and net revenue interests of the leases within the Prospect AMI, (iii) in the case of a farmout agreement, any contractual conditions, covenants or restrictions, such as acreage or depth limitations, continuous drilling requirements, reversionary rights or similar anticipated terms; and (iv) in the case of a lease, anticipated stipulations imposing obligations regarding archeological, cultural or other surveys, reports or similar requirements;

(d) an estimate of expenses incurred to date by the Participants in negotiating and obtaining the appropriate farmout agreement or leases;

(e) an estimate of the cost of drilling, completing and operating the exploration and development xxxxx proposed for each Prospect;

(f) the number of potential well locations in respect of the Prospect, and range of potential reserves;

(g) at a minimum, an integrated time or depth structure map at the primary objective and, if applicable, one seismic amplitude map at the primary objective; and

(h) any other available pertinent information.

Section 6. Prospect Participation and Operations.

(a) Within fifteen (15) days of the formal designation of a Prospect and Prospect AMI (“Election Date”), TechXplore shall make an election as to the initial working interest (“Working Interest”) it desires to own in the Prospect AMI by providing written notice thereof to Century. TechXplore may elect to participate for a five percent (5%), ten percent (10%), fifteen percent (15%), twenty percent (20%) or twenty five percent (25%) Working Interest in the Prospect AMI. If, prior to the Election Date, TechXplore notifies Century that it does not wish to take any Working Interest participation in the Prospect AMI or fails to elect to participate by the Election Date, the procedures in Section 6(f) shall apply and TechXplore shall have no Working Interest in the Prospect AMI other than its farm-out interest provided for in Section 6(f). On the Election Date, TechXplore shall be obligated to pay to Century its proportionate share of the Prospect fee as set forth Section 6(e).

(b) Century shall prioritize the Prospects and at its sole discretion determine the timing of leasing and drilling each Prospect. For each Prospect to be drilled and developed by the Participants, Century shall be the operator for such Prospect and the Participants shall enter into a Joint Operating Agreement, in a form substantially similar to the one contained in Exhibit “C” attached hereto (the “JOA”) that shall govern the Exploration Activities within the Prospect AMI (unless prior commitments under a farm-out agreement otherwise dictate that another operator or other form of operating agreement shall be used). The Parties shall record a memorandum of the JOA at the time the lease assignments are recorded.

(c) At such time that Century deems advisable, it shall commence the acquisition of leases within a specific Prospect AMI. TechXplore shall be obligated to fund its proportionate share of lease costs (as determined by the Working Interest percentage so elected in Section 6(a)). From time to time, Century shall invoice TechXplore for its share of lease acquisition costs and TechXplore shall remit payment to Century within thirty (30) days of receipt of Century’s invoice. Upon receipt of payment, Century shall assign to

TechXplore’s its proportionate share of the leases by means of an assignment in a form substantially similar to that contained in Exhibit “D” attached hereto (the “Assignment”). In the event that TechXplore does not timely pay Century for its share of lease acquisition costs as provided for herein, TechXplore shall have no right to participate in that Prospect AMI, except as provided for in Section 6(f).

(d) TechXplore shall pay for its Working Interest share of drilling and all other costs incurred in each Prospect AMI in accordance with the JOA.

(e) In addition to its obligation to fund its proportionate share of the costs attendant to acquiring leases and drilling and developing each Prospect, TechXplore shall pay to Century its proportionate share (to the extent of TechXplore’s Working Interest) of a Prospect fee equal to $200,000 per Prospect for the 8/8ths interest for any Prospect to be drilled to a true vertical depth of 5,000 feet or greater and $100,000 for the 8/8ths interest for any Prospect to be drilled to a true vertical depth of less than 5,000 feet. The Prospect fee is intended as a partial reimbursement to Century for general and administrative, geological and geophysical and seismic acquisition and reprocessing costs incurred by Century. The Prospect fee shall attach to all Prospects generated pursuant to this Agreement.

(f) In the event that TechXplore elects not to participate for a Working Interest with respect to any Prospect AMI, or elects to participate for a Working Interest less than twenty five percent (25%), Century or its designee shall have the exclusive right to acquire by farm-in the Working Interest not taken by TechXplore at a percentage equal to twenty five percent (25%) less the Working Interest percentage in which TechXplore elects at the Election Date (“Farm-in Interest”). Century or its designee shall pay one-hundred percent (100%) of the prospect fee and lease acquisition costs attributable to the Farm-in Interest and one-hundred percent (100%) of the drilling costs attributable to the Farm-out Interest to the casing point on the initial well drilled within the Prospect AMI. By funding these costs, Century or its designee shall earn a working interest in the Prospect AMI equal to seventy-five percent (75%) of the Farm-in Interest in the Prospect AMI. If, at the casing point, TechXplore elects to participate for the remaining twenty-five percent (25%) of the Farm-in Interest (which election shall be made within three (3) days of completion of logging and other formation evaluation tests conducted on the initial well drilled in the Prospect AMI), then TechXplore shall be obligated to fund its proportionate share of all ongoing costs of development of the Prospect attributable to that portion of the Farm-in Interest in accordance with the JOA and Century shall assign to TechXplore its proportionate share of the leases attributable to the remaining twenty-five percent (25%) of the Farm-in Interest by means of an Assignment. If TechXplore elects not to participate, or fails to make an election in the allotted time period, for such twenty-five percent (25%) of the Farm-in Interest in the Prospect at the casing point, Century or its designee shall earn one-hundred percent (100%) of Farm-in Interest in the Prospect AMI. For all operations conducted subsequent to the casing point of the initial well drilled within the Prospect AMI, Century or its designee shall be obligated to pay its actual proportionate share of all costs in accord with its ultimate working interest ownership in the Prospect AMI.

(g) Notwithstanding anything contained herein to the contrary, TechXplore’s working interest (prior to its option to acquire twenty five percent (25%) of the Farm-in Interest at the casing point of the initial well drilled within in any Prospect AMI) in the following Prospect AMI’s shall be as hereafter stipulated; (i) Bay St. Louis — zero percent (0%); (ii) Shamu — five percent (5%); (iii) Flipper — five percent (5%); (iv) Dory five percent (5%); (v) Barracuda — zero percent (0%); (vi) Trinidad - zero percent (0%); (vii) Trinidad North - zero percent (0%); (viii) Bayou Postillion North - zero percent (0%); zero percent (0%); (ix) Pierre Pass - zero percent (0%). Within thirty 30) days of execution of this Agreement, TechXplore shall reimburse Century for its proportionate share of the Prospect fee and lease acquisition costs already expended for the foregoing Prospects in which it has an initial working interest.

(h) If Century decides not to proceed with either the acquisition of leases or subsequent drilling of any Prospect, then at the earlier of (i) receipt of written notice by TechXplore from Century, which Century is not obligated to provide, stating that Century does not intend to drill the Prospect or (ii) two (2) years from the written designation of the Prospect, TechXplore shall have an option to farm-in to Century’s Percentage Interest in that Prospect on terms to be mutually agreed by the Participants.

Section 7. Special Provisions — Tuscaloosa Marine Shale. Notwithstanding anything herein contained to the contrary the following shall apply to the Tuscaloosa Marine Shale (“TMS”) AMI, the boundary of which is depicted in Exhibit “A-3”.

(a)

TechXplore waives its right to its Percentage Interest in the leases in the TMS AMI. In consideration of the foregoing, TechXplore is hereby granted a six and one quarter percent (6.25%) working interest after Project Payout (as hereinafter defined) from Century’s working interest in the leases acquired in the TMS AMI.

(b)

For purposes of this Section 7, “Project Payout” shall refer to that point in time at which Century has recouped from the sale of Hydrocarbons produced from the TMS AMI and/or from the sale of any or all of its working interest or royalty interest in the leases within the TMS AMI, all of its costs related to its Exploration Activities in the TMS AMI, including land, legal, seismic, drilling, completion, hookup and related operating expenses. The after Project Payout working interest shall be conveyed to and vested in TechXplore out of Century’s working interest at the time of Project Payout.

(c)

The APO XXX which would otherwise be applicable to an Exploration Area AMI shall be amended in the case of the TMS AMI, so that the same becomes a before payout over-riding royalty (“BPO XXX”), which shall be equivalent to a one and one half percent (1.5%) over-riding royalty carved out of Century’s working interest in each TMS AMI lease, and shall be assigned to TechXplore as soon as is practical after execution of this

Agreement. On any future leases acquired within the TMS AMI said assignment of the BPO XXX shall be made within ninety (90) days from such lease acquisition.

Section 8. After Payout Overriding Royalty. TechXplore shall be entitled to receive an after Payout (as hereinafter defined) overriding royalty interest (“XXX”) in and to each Prospect AMI (the “APO XXX”) that becomes subject to this Agreement. The APO XXX shall be granted at the time that the assignments of working interest within each Prospect AMI are conveyed, as described in Section 6(c). The APO XXX shall be the equivalent of one and one half percent (1.5%) on all leases in each Prospect AMI in which the assigned net revenue interest is seventy five percent (75%) or more, and shall be the equivalent of one percent (1%) on all leases in each Prospect AMI in which the assigned net revenue interest is less than seventy five percent seventy five percent (75%). For purposes of this Section 8, “Payout” shall be calculated on a well by well basis and be defined as that point in time at which all of Participants’ and/or assignees costs, including but not limited to drilling, completing, hooking-up, equipping and operating each well within each Prospect AMI (and for the first well drilled within the Prospect AMI, the Participants’ and/or assignees initial leasehold acquisition costs related to the Prospect AMI) have been recovered by the Participants out of the production from that particular well, after payment of royalties and other lease burdens (created prior to the time that the Participants acquire their interests therein), and severance taxes. TechXplore acknowledges and agrees that an additional after payout overriding royalty interest will be simultaneously assigned to other employees of Century’s Parent (“Century’s APO XXX”). Century’s APO XXX will be equal in all respects to the APO XXX. The total of both overrides will apply to the combined interests of all the Participants and each Participant shall bear its proportionate share of both the APO XXX and Century’s APO XXX.

Section 9. Term. This Agreement shall continue in full force and effect from the Effective Date to December 31, 2010 (the “Term”).

Section 10. Joint Operating Agreement. All leases jointly owned by Century and TechXplore acquired under the terms of this Agreement shall be subject to a JOA particular to each Prospect AMI. A JOA shall be executed for each Prospect AMI, with the appropriate operator designated. All operations conducted on any acreage or lease(s) included within a Prospect AMI shall be conducted pursuant to the JOA and if there is a conflict between this Agreement and the JOA, the provision of the executed JOA shall control for each Prospect AMI.

Section 11. Meetings. The Participants shall, from time to time, hold meetings (whether in person or telephonic ally) to discuss the conduct of the Exploration Activities. These meetings shall be held as frequently as deemed necessary, but in no event less than once each calendar month discuss. Notice shall be provided by the Participant proposing the meeting to the other at least five (5) business days in advance of the meeting, which shall specify the date, time, location and agenda for the meeting.

Section 12. Preferential Right to Purchase Producing Properties. Should TechXplore desire to sell all or any part of its interest in Hydrocarbons discovered pursuant to this Agreement, it shall give written notice to Century together with full information concerning the

interests proposed to be sold. Century shall have a right for a period of thirty (30) days after receipt of such notice to negotiate a cash purchase of such interests. In the event TechXplore is satisfied with Century’s cash offer, the Participants shall proceed with the closing of such a transaction within a period of sixty (60) days of such agreement. In the event that TechXplore is not satisfied with Century’s offer, it may conclude a sale of the Hydrocarbons to a third party, so long as any third party sale is concluded for consideration in excess of that offered by Century.

Section 13. Audits. TechXplore shall have the right to conduct audits of Century’s accounts and records relating to this Agreement. Any such audit shall be conducted in accordance with the procedures provided for in the XXXXX Addendum to the form of JOA attached hereto.

Section 14. Other Business Opportunities. During the Term, the Participants are free to pursue business opportunities affecting acreage outside of the Exploration Area independently or with third parties. However, within the Exploration Area it is understood that any such opportunities involving Exploration Activities, the acquisition of 3D or 2D seismic or the acquisition of producing Hydrocarbon properties shall be shared, on a first right of refusal basis, between the Participants in accordance with their Percentage Interests. When such an opportunity arises, the initiating Participant shall provide written notice to the other, such notice containing all of the particulars of the opportunity, including the financial requirements and time constraints for evaluation and investment. If the Participants agree to jointly pursue any such opportunity, the Participants shall be required to fund that opportunity in accordance with their respective Percentage Interests. It is understood and agreed that any acquisition of 3D Data and or the acquisition of new speculative seismic purchases to be undertaken during the Term shall be subject to Century’s approval at its sole discretion.

Section 15. Representations. Each party represents that it: (a) is duly organized in the State of its organization; and (b) is or shall be qualified to do business in and is in good standing in all jurisdictions where appropriate for the conduct of their respective businesses, including the business to conducted hereunder; and (c) has fulfilled all necessary corporate or other prerequisites for the execution and delivery of this Agreement and the performance of its respective obligations hereunder.
