a sufficient number of full-time lease brokers, as may be available, to attempt to lease additional net mineral acres. By its execution hereof, Participant commits to participate, for Participants Share, in the acquisition of all Additional
Leases. Any lease acquired beyond the Twenty Million Dollar commitment shall be subject to Article II.C. below and shall be considered an Additional Lease, if and only if, Participant elects to acquire its share of such Lease Costs.

Beginning October 15, 2010 and on a monthly basis thereafter, Southern Bay may request an advance of funds representing
Participants Share of the estimated expenditures for Additional Leases. Such estimated amount will be paid by Participant within fifteen (15) days of the invoice for such advance. Southern Bay and Participant acknowledge that the amount
of additional leases actually acquired cannot be estimated with precision, particularly within any specific monthly period. The amount of the requested advance shall not exceed One Million Dollars & No/100 ($1,000,000.00) without the

---

to or less than seventy-five percent (75%), then Southern Bay will not reserve any overriding royalty and the actual net revenue interest will be assigned. At the time of such assignment,
Participant shall pay Southern Bay for Participants Share in the Additional Leases an amount equal to the Lease Costs incurred by Southern Bay in acquiring the Additional Leases, all multiplied by Participants Share. Said payment shall
be reduced by any funds advanced to Southern Bay by Participant for leasing.

| | a. | furnish the other Party with the approximate location of the well then being drilled and the name of the Operator or drilling contractor drilling the well,
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | disclose in detail the reasons why the well can reasonably be expected to materially affect the value of the offered AMI Lease, and
| | -- | -----------------------------------------------------------------------------------------------------------------------------------



| | c. | specifically advise the other Party that it shall have no more than the period of three (3) days (exclusive of Saturday, Sunday and holiday), within which to elect
to acquire an interest in the offered AMI Lease.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

invoice. Upon receipt of such reimbursement the acquiring Party shall execute and deliver an appropriate assignment to the other Party. If the acquiring Party does not receive the amount due from the other Party within fifteen (15) days after
the receipt of the invoice for its costs, the acquiring Party may give written notice to the other Party that the failure to pay the amount due within five (5) days at the acquiring Partys option, constitute a withdrawal by the other
Party of its former election to acquire the interest, and the other Party shall no longer have the right to acquire an interest in the offered AMI Lease. If the acquiring Party does not elect to treat such nonpayment as a withdrawal of the election
to participate in the acquisition, the other Party shall remain liable for payment.

| | 6. | Material Acquisitions. In the event either Party elects to pursue a Material Acquisition that is located within the AMI, in a market offering or
in a negotiated transaction, such Party will reasonably notify the other and may require the other to participate in the evaluation and due diligence process and closing thereof, simultaneously and in cooperation with the Party pursuing such
transaction. The Parties hereto acknowledge time is of the essence in such potential transactions and that timely notification cannot be specified time certain. Accordingly, for this purpose of notification, the Party pursuing such a transaction
shall advise the other when it has reasonably compiled relevant information related to the potential acquisition, including technical and economic data related thereto, but

---

| | not later than such time when a letter of intent has been accepted and executed by the seller or when verbal acceptance of an offer has been received from the seller or their brokers or advisors.
The Party receiving such notice will use its commercially reasonable best efforts to advise the other of its intent to proceed and participate in the transaction, as early as reasonably possible. The election to participate will be documented by a
mutually agreeable joint acquisition agreement, which describes the proposed acquisition, location, purchase price and expected timing of closing. Such agreement will, further specify the maximum acquisition cost above which the participating Party
will relinquish the right of participation. Said agreement will be subject to the terms and conditions of definitive purchase and sale agreement (PSA) between buyer and seller. The participating Party will proportionately fund and be
obligated to the terms of the PSA. The participating Party shall fund its share of any deposits or escrow obligations and the net Acquisition Cost forty-eight (48) hours prior to the timing specified in the PSA. Failure to fund shall result in
the defaulting Party relinquishing any right to participate and further relinquish any deposits or escrow payments previously paid.

(75%) net revenue interest, proportionately reduced, in each such lease to the acquiring party; provided, if the net revenue interest of any lease is equal to or less than seventy-five percent (75%), then offering Party will not reserve any
overriding royalty and the actual net revenue interest will be assigned.

of the purchase price, provided, however, that either Party shall assign to the other its proportionate share of any warranty held. The assignment shall be made and accepted subject to, and the Assignee shall expressly assume its portion of all of
the contractual obligations of Assignor under or with respect to an assigned AMI Lease, of which Assignee gave notice to Assignor prior to its election to acquire its share of the relevant AMI Lease.

III. DRILLING AND DEVELOPMENT.

A. Horizontal Obligation Wells. Southern Bay shall propose the drilling of six (6) net Horizontal Obligation Wells to the joint venture interest, on locations reasonably acceptable to
Participant, and shall use its reasonable efforts to enable the first such well to be spud on or before April 1, 2011 and the other five (5) such wells to be drilled and completed in calendar year 2011 (the Horizontal Obligation
Wells) as is reasonably possible based on existing industry conditions. If Southern Bay and Participant cannot agree on a location reasonably



---

acceptable to Participant, Southern Bay shall have the final determination as to the location of such Horizontal Obligation Well. Each of the Horizontal Obligation Wells shall be drilled on a
Spacing Unit agreed by the Parties, or unless otherwise required by governmental regulation or order. The procedure for proposing a Horizontal Obligation Well shall be that set forth in Article VI.B., of the Operating Agreement; provided, however,
Participant shall participate in the drilling, completion and equipping of each of the six (6) net Horizontal Obligation Wells and, notwithstanding the Operating Agreement, shall have no right to elect not to participate (be
non-consenting) in the drilling, completion and equipping through the tanks of any of the Horizontal Obligation Wells. A well shall constitute a Horizontal Obligation Well if it is drilled to and penetrates the Eagle Ford formation
whether or not the drilling thereof is discontinued and whether or not such well is completed. However, if drilling of a Horizontal Obligation Well is terminated before completion of the drilling due to mechanical problems or impenetrable strata or
other conditions in the hole which make further drilling impracticable, under generally accepted oil field practices, and if Southern Bay determines to drill a substitute well on such Spacing Unit, the substitute well shall be a substitute for the
original Horizontal Obligation Well within that Spacing Unit and shall not constitute a new Horizontal Obligation Well. Participant further agrees that it will pay one-hundred percent (100%) of the drilling, completing and equipping costs
through the tanks of all six (6) net Horizontal Obligation Wells.

B. Subsequent Wells. After drilling, completion and equipping
of the six (6) net Horizontal Obligation Wells, Southern Bay shall have the option, but not the obligation, to propose Subsequent Wells, on locations reasonably acceptable to Participant. If Southern Bay and Participant cannot agree on a
location reasonably acceptable to Participant, Southern Bay shall have the final determination as to the location of such Subsequent Wells. Each of the Subsequent Wells shall be drilled on a Spacing Unit agreed by the parties, or unless otherwise
required by governmental regulation or order. Any additional drilling will be in accordance with the Operating Agreement and the provisions of this Agreement; provided, the foregoing shall be subject to revisions based on economic conditions and
factors in existence or reasonably anticipated at that time. It is further acknowledged and agreed that should Participant elect not to participate in the initial well drilled in a proposed Spacing Unit then Participant shall forfeit and assign back
to Southern Bay any rights and ownership Participant has in said Spacing Unit.

If Participant elects not to participate in a
proposed Subsequent Well, after the initial well has been drilled in a Spacing Unit, and such Subsequent Well is drilled pursuant to the terms in the Operating Agreement, then Participant shall be deemed non-consent as defined in Article VI.B. of
the Operating Agreement.

C. Participants Services, Rigs & Products. Southern Bay shall utilize Participants
Affiliates services for the drilling, completing, equipping, servicing, re-working and abandoning of all wells spudded in the AMI subject to this Agreement as set forth under Exhibit I to the JOA.



---



D. Failure To Perform.
If Participant fails to drill all six (6) net Horizontal Obligation Wells to the joint venture interest, as otherwise described in Article III.A., Participant agrees that within thirty (30) days following its notice of non-complianceto
cure said non-compliance by:

1. Drill, complete and equip the remaining six (6) net Horizontal Obligation Wells specified in this
Agreement; or

2. Pay to Southern Bay liquidated damages equal to Two Million Five Hundred Thousand Dollars & No/100 ($2,500,000.00)
multiplied by the number of undrilled Horizontal Obligation Wells; or

3. Assign back to Southern Bay one sixth
(1/6th) of its original leasehold/working interest in
and to all remaining undeveloped leases within the AMI for each un-drilled obligation well

Any and all wells drilled
subsequent to the satisfaction of one of the remedies specified immediately above will be considered Subsequent Wells as specified in Article III.B. above.

IV. OPERATIONS WITHIN PROJECT AREA

A. Operating Agreement. All operations
within the Project Area shall be conducted pursuant to the joint operating agreement attached hereto as Exhibit C (Operating Agreement), reference to which is hereby made for all purposes, except as expressly modified by the
terms hereof. Southern Bay Operating, LLC shall be designated as Operator subject to the resignation and removal provisions of the Operating Agreement. In the event there are other parties in the Spacing Unit for a well hereunder that are not a
participant with Southern Bay under this or a similar agreement, Participant agrees to support Southern Bay Operating, LLC as the designated operator subject to the resignation and removal provisions of the Operating Agreement. In the event of a
conflict between this Agreement and the Operating Agreement, this Agreement shall control.

B. Third Party Operating Agreements.
To the extent that a well within the Project Area is operated by a third party (excluding a Third Party Participant), the Parties shall be subject to the terms of any operating agreement negotiated with such third party operator. To the extent there
are conflicts between Third Party Operating Agreements and this Agreement, this Agreement will prevail between the parties hereto inclusive of the non-consent provision in Article III.B.

V. PROPORTIONATE REDUCTION

A. Proportionate Reduction Clause: If an oil, gas and mineral lease or other Mineral Interest covers less than the entire mineral fee estate, or if a Partys interest in the applicable lease
or Mineral Interest is less than a one-hundred percent (100%) ownership interest, any interest conveyed or reserved pursuant to this Agreement is intended to be proportionately reduced to accord to (i) the proportion of mineral interest
covered by the relevant oil and gas

lease or other Mineral Interest, and (ii) the proportion of ownership held by the conveying party, in the case of a conveyance, or the burdened party, in the case of a reservation of
interest.

VI. SEISMIC PROPOSALS

A. Seismic Proposals: During the term of the Operating Agreement the Parties may propose to acquire or license seismic data within the AMI. Southern Bay shall act as operator in the
acquisition and processing of new seismic data. Southern Bay shall also act as operator in the acquisition of existing seismic data and re-processing if determined necessary. In the event a Party elects to participate in the licensing of seismic
data all Parties participating will make an election at that time as to acquire or not to acquire a license to the data. In the event a Party elects to participate in acquiring the seismic but not acquire a license that Party shall have all rights
to review and interpret such data allowed under the license agreement. In the event a Party (Rejecting Party) elects not to participate in the proposed seismic program and the other Party (Proposing Party) proceeds to acquire
the proposed data, the following shall apply:

1. 2D Seismic Program Proposals: A Rejecting Party with respect
to any 2D seismic program shall pay to the participating Parties under the joint account a Twenty-Five Thousand Dollars & No/100 ($25,000.00) seismic fee upon spudding of each well within the AMI in which the Rejecting Party participates
until the participating Parties have recovered one-hundred percent (100%) of their actual total costs (licensing or acquisition, processing, tape copy, etc.) for the proposed seismic acquisition

2. 3D Seismic Program Proposals: A Rejecting Party with respect to a 3D seismic program shall pay a Fifty Thousand
Dollars & No/100 ($50,000.00) seismic fee upon spudding for each well within the AMI in which the Rejecting Party participates until the participating Parties have recovered seventy-five percent (75%) of their actual costs (licensing
or acquisition, processing, tape copy, etc.).

3. Upon the Rejecting Party paying any amounts under 1., or 2., above, and
to the degree that it is allowed under the license agreement for licensed data, Rejecting Party shall be entitled access to the seismic data, and the right to review and interpret such seismic data in the office of the Proposing Party, and the right
to review Participants interpretation, all limited to the proposed Spacing Unit and lands within one mile of the Spacing Unit.

4. It is understood that the recovered costs described under 1., or 2., above in cumulative may eventually be in excess of the Rejecting Parties actual cost to acquire the data in order to mitigate the
risk to and time value of the monies expended by the participating Parties.

B. Seismic Parameters: Proposing Party
shall submit for review to all parties an estimated cost and detailed description of the data acquisition, processing parameters, and acquiring and processing contractors, so that Non-Proposing Party may evaluate the proposal.

VII. CONFIDENTIALITY

A. Confidentiality. The parties acknowledge that the Project Area information that is the subject matter of this Agreement
(including but not limited to all well information acquired by operations conducted under the Operating Agreement) is sensitive and confidential proprietary information belonging to the parties. Each Party, for itself and its Affiliates, agrees not
to release or disclose or otherwise make the information available to or to furnish any of said information to any third party without (i) obtaining the agreement of the third party to maintain such information confidential and to not use such
information other than in connection with investing in or participating with or purchasing interests from the disclosing party, or (ii) first obtaining the express written consent of the other Party. Any such release or disclosure if approved
shall be conditioned upon the third party expressly agreeing to all terms herein and becoming a party to and subject to this Confidentiality Agreement. This restriction on use and disclosure of this information shall remain in effect for a term of
two (2) years following the Effective Date. Nothing contained above shall restrict or impair any Partys right to use or disclose any of the information which is: (1) at the time of disclosure available to the public through no act or
omission of that Party; (2) can be shown was lawfully in that partys possession prior to the time of this Confidentiality Agreement; or (3) is independently made available to that Party by a third party who is independently entitled
to disclose such information and that party shows that the right of such third party to disclosure existed prior to the date of this Agreement.

B. Public Disclosure. Subject to the exceptions set forth below, prior to substantial leasing completion in the AMI as contemplated by this
Agreement, each Party (specifically including GeoResources, Inc, a publically traded company and the corporate parent of Southern Bay) agrees to notify the other of its intent to issue press releases or make other public disclosures related to this
Agreement, at least forty-eight (48) hours prior to such disclosure (exclusive of Saturdays, Sundays or holidays). Any proposed press release or other disclosure shall be provided to the other Party with such notice on a confidential basis for
its information and comment. The Party proposing such disclosure agrees to reasonably consider any comments and suggestions made by the other Party. Notwithstanding such intent, either Party may make any public disclosure to the extent that, upon
advice of such Partys counsel, such disclosure is advisable to comply with United States or state securities laws, rules or regulations.

VIII. TAX ELECTION

This Agreement is not intended to create, and shall
not be construed to create, a relationship of partnership or an association for profit between or among the Parties hereto except as provided herein. Each Party hereby affected elects to be excluded from the application of all the provisions of

IX. PAYMENT OF DELAY
RENTALS AND LEASE EXTENSIONS

Southern Bay shall be responsible for making any payment of delay rentals, shut in royalties
and minimum royalty payments on Mineral Interests in the Contract Area. Participant shall bear and pay its Participants Share of such payments. Participant shall be billed and shall pay for said costs in the manner set forth for the billing
and paying of direct costs in the COPAS accounting procedures attached to the form of Operating Agreement. Operator shall not be liable to Participant for any loss resulting from a good faith effort to properly do so.

Extensions of Leases shall be governed by the following: Southern Bay shall be responsible to inform Participant of Southern Bays
election to extend or not to extend the primary term no later than forty-five (45) days prior to the expiration of the Leases original primary term or prior to the date in which such election must be made, whichever is earlier.
Participant shall inform Southern Bay of its election to extend or not to extend no later than fifteen (15) days after being so notified. Southern Bay shall accordingly extend the primary term of any Lease which one or both of the Parties
desire to extend. Notwithstanding the foregoing covenant, neither Party shall incur liability to the other Party for failure to give the required notice unless such failure results from gross negligence or willful misconduct. Southern Bay Party
shall subsequently invoice Participant based on the Participants election decision as well as the election decision of Southern Bay. Participant shall reimburse Southern Bay within thirty (30) days of receipt of invoice.

X. NO JOINT LIABILITY

The rights, duties, obligations and liabilities of the parties hereto shall be several and not joint or collective. Each Party hereto shall be responsible only for its obligations as herein set out and
shall be liable only for its share of the cost and expense as herein provided; it being the express purpose and intention of the Parties that their interest in this Agreement and the rights and property acquired in connection herewith shall be held
by them as tenants in common. Except for the tax election which the Parties may have made, it is not the purpose or intention of this Agreement to create any mining partnership, commercial partnership or other partnership.

L. Arbitration: Any dispute arising under this Agreement (Arbitrable Dispute) shall be referred to and resolved by binding arbitration
in Houston, Texas, to be administered by and in accordance with the Commercial Arbitration Rules of the American Arbitration Association. Arbitration shall be initiated within the applicable time limits set forth in this Agreement and not thereafter

N. Not to be Construed Against Drafter:The Parties acknowledge that they have had an adequate opportunity to review each and every provision contained in this Agreement, that they have
participated equally in the drafting hereof and that they have had adequate time to submit same to legal counsel for review and comment. Based on said review and consultation, the parties agree with each and every term contained in this Agreement.
Based on the foregoing, the parties agree that the rule of construction that a contract be construed against the drafter, if any, shall not be applied in the interpretation and construction of this Agreement.

O. Laws and Regulations: Any reference to any federal, state, local, or foreign statute or law will be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context otherwise requires.

P. Third-Party Beneficiaries: This Agreement is not
intended to confer any rights or remedies upon any Person other than the Parties and their respective successors, legal representatives and permitted assigns.

Q. Investment Representations: Participant understands (1) that the interests evidenced by this Agreement have not been registered under the United States Securities Act of 1933, or any state
securities laws (the Securities Acts), (2) that Southern Bay has relied upon the fact that the interests are to be held by Participant for investment, (3) that exemption from registration under the Securities Acts may not be
available if the interests were acquired by Participant with a view to distribution, and (4) Participant is an accredited investor as defined in Regulation D adopted by the Securities and Exchange Commission.

Accordingly, Participant hereby confirms to Southern Bay that it is acquiring the interests for its own account, for investment and not
with a view to the resale or distribution thereof. Participant agrees not to transfer, sell or offer for sale any or any portion of the interests unless there is an effective registration or other qualification relating thereto under the Securities
Act of 1933 and under any applicable state securities laws or unless the Participant delivers to Southern Bay, if Southern Bay requests, an opinion of counsel, that such registration or other qualification under such Act and applicable state
securities laws is not required in connection with such



---

transfer, offer or sale. Participant understands that Southern Bay is under no obligation to register the interests or to assist Participant in complying with any exemption from registration
under the Securities Acts if Participant should at a later date, wish to dispose of the interests.

Prior to acquiring the
interests, Participant has made an investigation of Southern Bay and its business and has had made available to it all information with respect thereto which it needed to make an informed decision to acquire the interests. Participant considers
itself to be an entity possessing experience and sophistication as an investor which are adequate for the evaluation of the merits and risks of its investment in the interests.

R.Related Party Transactions.If Southern Bay or Participant engages or enters into any transaction with an Affiliate or other party related by ownership, control or family to Southern
Bay or Participant, or any of their executives with respect to a matter for which Southern Bay or Participant may bear any portion of the economic cost under this Agreement, such engagement or transaction and the economic particulars of the
relationship shall be fully disclosed to the other Party, and such engagement shall be on terms no less favorable than are available in the market in an arms length engagement or transaction. Southern Bay or Participant shall provide
documentation reasonably requested by either party to evidence compliance with this provision.

S.Prior Agreements. Southern
Bay and Participant hereby acknowledge and agree that this Agreement is subject to the terms and provisions contained in an unrecorded Letter of Intent dated September 3, 2010 and the terms and provisions contained in the Operating Agreement
attached hereto as Exhibit C. Southern Bay and Participant further acknowledge and agree that should there be any conflict between the terms and provisions contained in this Agreement and those terms and conditions contained in said
Letter of Intent and said Operating Agreement, the terms and conditions of this Agreement shall prevail.

IN WITNESS WHEREOF,
this Agreement is executed effective as of the date hereinabove provided.
