ARTICLE 4

TITLE DEFECTS

4.1 Defensible Title. The term “Defensible Title” with respect to a Lease means such title of Sellers (which may be held of record in the name of Sellers or in the name of one of Sellers’ lease brokers or agents so long as such lease brokers or agents assign the Leases held by them to Sellers at or prior to Closing) in and to the Leases that, subject to and except for Permitted Encumbrances: (i) results in Sellers owning that number of Net Acres with respect to the Lease equal to the number of Net Acres for the Lease set forth in Exhibit A, (ii) entitles Sellers to not less than the Represented NRI, as defined herein; and (iii) is free and clear of liens, security interests, encumbrances, claims, lis pendens, and any other defects, other than Permitted Encumbrances.

The respective working interests of the Sellers in the Leases are as follows:


Seller		Working Interest
Arkoma ▇▇▇▇▇▇, LLC		0.40
Long Properties Trust		0.40
▇▇▇▇▇▇▇▇ Drilling Co., Inc		0.20
Total:		1.00

As used herein, the “Represented NRI” with respect to a Lease shall mean an amount equal to the difference between 100% and the Lessor’s Royalty for such Lease, as shown on Exhibit A.

4.2 Permitted Encumbrances. The term “Permitted Encumbrances” shall mean:

(a) lessors’ royalties; provided the net cumulative effect of such burdens does not operate to reduce the NRI, on a Lease-by-Lease basis, below the Represented NRI with respect to such Lease;

(b) all rights to consent by, required notices to, filings with, or other actions by federal, state or local governmental bodies, in connection with the conveyance of the applicable Lease if the same are customarily sought after Closing;

(c) rights of reassignment contained in any agreement providing for reassignment upon the surrender or expiration of any Leases;

(d) easements, rights-of-way, servitudes, permits, surface leases and other rights with respect to surface operations, on, over or in respect of any of the Leases or any restriction on access thereto that do not materially interfere with the operation of the affected Lease;

(e) liens created under deeds of trust, mortgages and similar instruments by the lessor under a Lease covering the lessor’s surface and mineral interests in the land covered thereby which would customarily be accepted in taking oil and gas leases or purchasing undeveloped oil and gas leases and for which the lessee would customarily seek a subordination of such lien to the oil and gas leasehold estate prior to conducting drilling activities on the lease;

(f) liens for taxes or assessments not yet due and delinquent or, if delinquent, that are being contested in good faith in the normal course of business;

(g) such Title Defects as Buyer has waived; and

(h) minor defects and irregularities in title or other restrictions that are of the nature customarily accepted by prudent purchasers of oil and gas properties and do not materially affect the value of any Lease encumbered thereby or materially impair the ability of the lessee to use any such property in its operations; provided the effect thereof does not operate to reduce the net revenue interest in such Lease below the Represented NRI with respect to such Lease.

4.3 Title Defect. The term “Title Defect” means with respect to a Lease any lien, encumbrance, adverse claim, default, expiration, failure, defect in or objection to real property title, other than Permitted Encumbrances, that alone or in combination with other defects renders Sellers’ title to the Lease less than Defensible Title.

4.4 Defect Value. “Defect Value” means with respect to a Lease the amount by which the value of the applicable Lease has been reduced by a Title Defect. The Defect Value shall be determined by the Parties in good faith taking into account all relevant factors, including without limitation, the following:

(a) If the Title Defect is a lien or encumbrance on the Asset, the Defect Value shall be the cost of removing such lien or encumbrance, not to exceed the Allocated Value of the affected Lease.

(b) If the Title Defect is an actual reduction in NRI below the Represented NRI with respect to the affected Lease, the Defect Value shall be, at Buyer’s option, an amount equal to the difference between the Per Acre Price based on the Represented NRI for such Lease and the Per Acre Price based on the actual NRI for such Lease; multiplied by the Net Acres for the Lease, as set forth in Exhibit A. Alternatively, for an Asset with an actual NRI that is below the Represented NRI, Buyer shall have the right to deem such Asset an Unresolved Title Dispute and exclude such Asset from Closing.

(c) If the Title Defect is such that the actual Net Acres covered by the Lease is less than the number of Net Acres set forth in Exhibit A for such Lease, the Defect Value shall be an amount equal to such difference in Net Acres multiplied by the Per Acre Price for such Lease. Provided, however, if the Title Defect is such that the actual Net Acres covered by the Lease is less than 50% of the number of Net Acres set forth in Exhibit A for such Lease, the Buyer shall have the right to deem such Asset an Unresolved Title Dispute and exclude such Asset from Closing.

4.5 Notice of Title Defects. On or before February 25, 2011 (the “Defect Notice Date”), Buyer shall deliver to Sellers a written notice of Title Defects describing in reasonable detail (i) the Title Defect, (ii) the basis of the Title Defect and (iii) Buyer’s good faith estimate of the reduction in the Lease’s Allocated Value caused by the Title Defect (“Title Defect Value”). The failure of Buyer to timely notify Sellers of a Title Defect (other than a Title Defect arising by, through or under Sellers or their affiliates or their respective agents) on or before the Defect Notice Date shall be deemed a waiver by Buyer of such Title Defect.

4.6 Defect Adjustments. If an Asset is affected by an undisputed Title Defect and the Parties have agreed upon the Defect Value attributable thereto, the Purchase Price will be reduced by the Defect Value attributable thereto unless Sellers cure the Title Defect on or before 5:00 p.m. Central Time three (3) days before Closing.

4.7 Unresolved Title Disputes. If, by the Closing Date, the Parties have not resolved any dispute regarding (i) the existence and scope of a Title Defect, (ii) the amount of the Defect Value, or (iii) the adequacy of Sellers’ Title Defect curative materials (each such matter, together with the matters described in the last sentence of Section 4.4(b) and the last sentence of Section 4.4(c), an “Unresolved Title Dispute”), then, unless waived by Buyer, the affected Leases shall be excluded from the Assets delivered at Closing, and the Purchase Price payable at Closing shall be reduced by an amount equal to the aggregate Allocated Values of the excluded Leases (the “Excluded Leases”). For a period of ninety (90) days following the Closing Date (or such longer period of time to which the Parties may mutually agree in writing) (the “Cure Period”), Sellers shall have the right, but not the obligation, to continue attempting to cure the Title Defects with respect to the Excluded Leases. If Sellers reasonably cure a Title Defect within the Cure Period, or Buyer notifies Sellers that it waives such Title Defect, then, within thirty (30) days after obtaining such title curative, Sellers shall assign to Buyer an undivided 87.5% working interest in the affected Excluded Lease(s), subject to and in accordance with the terms hereof, and Buyer shall pay Sellers the amount by which the Purchase Price was reduced due to the relevant Title Defect, such amount to be paid 1/3 in cash, and 2/3 in Common Stock, in accordance with Section 2.1(b). If a Title Defect is neither cured to Buyer’s reasonable satisfaction nor waived by Buyer prior to the expiration of the Cure Period then the Excluded Lease(s) affected thereby shall be retained by Sellers and neither Buyer nor Sellers shall have any further obligation to the other Party with respect thereto.

4.8 Consents. Prior to Closing, Sellers shall use reasonable efforts to obtain all required consents to assignment of the Assets. If Buyer discovers properties for which consents to assign are applicable during the course of Buyer’s due diligence activities, Buyer shall notify Sellers immediately and Sellers shall use reasonable efforts to obtain such consents prior to Closing. Except for consents and approvals which are customarily obtained post-Closing (including without limitation federal, state, or other governmental approvals), if a consent to assign any Asset has not been obtained as of the Closing Date, then at Buyer’s election, the affected Asset(s) shall be (a) conveyed to Buyer and the respective consents obtained by Buyer post-Closing and Buyer shall assume the risk of not obtaining such consents (provided that after Closing Sellers shall continue to cooperate with Buyer to obtain such consent), (b) retained by Sellers and the Purchase Price shall be reduced by the Allocated Value of such Asset, or (c) at the option of Buyer, held by Sellers on behalf of Buyer for a three (3) month period of time to obtain any consent to assign, and if such consent is not obtained within such time period then Sellers shall retain such Asset and refund Buyer the Allocated Value attributed thereto.

4.9 Purchase Price Adjustments; Settlement Statement. The aggregate amount of any adjustment of the Purchase Price pursuant to Sections 4.6, 4.7, 4.8, and 4.11, and any other adjustments permitted elsewhere in this Agreement or agreed to by the Parties (collectively, “Purchase Price Adjustments”) shall be applied as follows: (i) the Stock Consideration shall be adjusted by an amount equal to the aggregate Purchase Price Adjustment multiplied by 2/3; and (ii) the Closing Cash Consideration shall be adjusted by an amount equal to the aggregate Purchase Price Adjustment multiplied by 1/3. The aggregate adjustment of the Purchase Price shall be borne by each Seller in proportion to the respective share of the Purchase Price allocated to such Seller, as shown on Exhibit B; provided, however, that if a downward adjustment to the Purchase Price is made with respect to a Title Defect that arises by, through or under one or more, but not all, of the Sellers, the reduction in the Purchase Price shall be borne by the Sellers under or through whom the Title Defect arose. At least two (2) business days prior to Closing, Sellers shall deliver to Buyer a settlement statement (“Settlement Statement”) setting out all Purchase Price Adjustments, determined as provided herein.

4.10 Subrogation of Warranties. Sellers shall grant to Buyer, its successors and assigns, full power and right of substitution and subrogation in and to all covenants, indemnities and warranties (including warranties of title) given or made by preceding owners, vendors, or others with respect to the Assets.

4.11 Title Benefit. The term “Title Benefit” with respect to a Lease means such title of Sellers (which may be held of record in the name of Sellers or in the name of one of Sellers’ lease brokers or agents so long as such lease brokers or agents assign the Leases held by them to Sellers at or prior to Closing) in and to the Lease that results in (i) Sellers owning greater than the number of Net Acres for the Lease set forth in Exhibit A (an “Acreage Increase”); or (ii) Sellers owning greater than the Represented NRI with respect to such Lease (an “NRI Increase”). On or before the Defect Notice Date, each of Buyer and Sellers shall notify the other Party in writing of any Title Benefit discovered on or before such date. Sellers shall be entitled to an upward adjustment to the Purchase Price with respect to each such Title Benefit equal to (a) in the case of an Acreage Increase, the amount by which Sellers’ actual Net Acres with respect to the affected Lease exceeds the Net Acres attributed to such Lease in Exhibit A, multiplied by the Per Acre Price for such Lease; and (b) in the case of an NRI Increase, an amount equal to the difference between the Per Acre Price based on the Represented NRI for such Lease and the Per Acre Price based on the actual NRI for such Lease; multiplied by the Net Acres for the Lease, as set forth in Exhibit A.

Upon Closing, Buyer shall assume and pay, perform, fulfill and discharge all claims, costs, expenses, liabilities and obligations relating to the ownership or operation of the Assets (including those arising under environmental laws and all plugging and abandonment obligations) attributable to periods on or after the Effective Time (the “Assumed Liabilities”). Sellers stipulate that no surface locations, drilling or production operations have been initiated on the Assets by Sellers.

12.2 Indemnification.

(a) Losses. “Losses” shall mean any actual losses, costs, expenses (including court costs, reasonable fees and expenses of attorneys, technical experts and expert witnesses and the cost of investigation), liabilities, damages, demands, suits, claims, and sanctions of every kind and character (including civil fines) arising from, related to or reasonably incident to matters indemnified against; excluding however any special, consequential, punitive or exemplary damages, loss of profits incurred by a Party hereto or Loss incurred as a result of the indemnified party indemnifying a third party, except to the extent the indemnified party suffers such damages to a third party (other than as a result of the indemnified party’s indemnification of such third party).

(b) Sellers’ Indemnification of Buyer. If the Closing occurs, each Seller shall defend, indemnify, and save and hold harmless Buyer, its officers, directors, employees and agents, from and against all Losses which arise directly or indirectly from or in connection with (i) any breach by such Seller of this Agreement; (ii) the Eco Resources Letter Agreement or the litigation disclosed in Schedule 5.7 (collectively, “Existing Litigation Losses”), or (iii) any breach by such Seller, prior to the Closing Date, of the Leases; provided, however, such Seller shall have no liability to Buyer for any claim by Buyer for breach of Sections 5.7, 5.8, 5.9, 5.10, 5.11, 5.12, 5.13 or 5.14 that is not made within six (6) months after the Closing Date. As provided in Section 13.17 herein, the obligations of the entities comprising Seller are several, not joint and collective, and in no event shall any Seller be liable to indemnify Buyer hereunder from any Losses arising from a breach by any other Seller of this Agreement or the Leases. Notwithstanding any other provision hereof, (i) in no event shall Buyer be entitled to indemnification from a Seller hereunder from Losses which, in the aggregate, exceed such Seller’s portion of the Purchase Price, as adjusted as provided herein; and (ii) except with respect to Existing Litigation Losses, Buyer shall not be entitled to indemnification from Sellers unless the aggregate amount of Losses covered by this Section 12.2(b) exceeds $200,000.00 (the “Indemnity Threshold”), such amount being a threshold, not a deductible; provided that Existing Litigation Losses shall not be subject to the Indemnity Threshold.

(c) Buyer’s Indemnification of Sellers. If the Closing occurs, Buyer shall defend, indemnify, and save and hold harmless Sellers, their officers, directors, employees and agents, from and against all Losses which arise directly or indirectly from or in connection with (i) the Assumed Liabilities, and (ii) any breach by Buyer of this Agreement.

12.3 No Insurance; Subrogation. The indemnifications provided in this Article 12 shall not be construed as a form of insurance. Buyer and Sellers hereby waive for themselves, their successors or assigns, including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Buyer and Sellers shall obtain waiver of such subrogation from its respective insurers.

12.4 Reservation as to Non-Parties. Nothing herein is intended to limit or otherwise waive any recourse Buyer or Sellers may have against any non-party for any obligations or liabilities that may be incurred with respect to the Assets.

EACH OF THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT AND ANY AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING INTO THIS AGREEMENT.
