(g) To the extent assignable or transferable by Seller, originals (to the extent an original is available) or copies at Buyer’s cost (if originals are unavailable), (in electronic format if available), of all of the files, records, information and data directly pertaining to the Properties in Seller’s possession, or to which a copy is readily available to Seller, including, without limitation, title records, abstracts, title opinions, title certificates, computer records,

The purchase and sale of the Properties shall be effective as of January 1, 2010 at 12:01a.m., in the time zone in which the Property is located (herein called the “Effective Time”).

The purchase price for the Properties is One Hundred Fifty Million and no/100 US Dollars (US$150,000,000.00) (“Purchase Price”), which shall be subject to adjustment as set forth in Section 2.03 below. Contemporaneous with the execution of this Agreement, Buyer has paid by immediately available funds to Seller an amount equal to five percent (5%) of the above stated Purchase Price as an earnest money deposit (the “Deposit”), which sum shall be credited against the Purchase Price at Closing in accordance with Section 2.03(b)(1), but shall only be subject to refund if this Agreement is terminated pursuant to Section 10.02.

Buyer agrees to provide to Seller as additional consideration certain collateral described in this Section 2.02 to secure Buyer’s Plugging and Abandonment (defined in Section 6.01(d) below) obligations under this Agreement. If Closing occurs:

(a) Buyer agrees to provide to Seller a combination of the following (at Buyer’s option) in the Collateral Amount hereinafter provided in Section 2.02(b):

(b) Buyer shall on or before the dates shown below ensure that the Collateral is provided to Seller in the amounts shown in the table below (the “Collateral Amount”):

(c) Notwithstanding anything contained herein to the contrary, in the event Buyer has performed Plugging and Abandonment with respect to a Property to satisfy a Plugging and Abandonment obligation that existed prior to the Effective Date, the total Collateral Amount required shall be reduced by an amount equal to the amount that the MMS Bonding Unit has assigned to the applicable Lease for such Plugging and Abandonment for such operation. For example, if a well is plugged and abandoned and the MMS Bonding Unit assigns a value of $1 million to such well, the total ending Collateral Amount will be reduced from $103 million to $102 million.

(d) In the event the MMS Bonding Unit accepts from Buyer supplemental bonds or other additional security for one or more of the Leases pursuant to 30 CFR 256.53 (d) and (e) (collectively, “Supplemental Bonds”), to the extent Supplemental Bonds apply to Plugging and Abandonment obligations existing on one or more Leases prior to the Effective Date, the required Collateral Amount of Collateral shall be reduced by the sum of Supplemental Bonds which satisfy the following conditions (collectively, the “MMS Collateral”):

In the event the surety reduces the bond’s amount without (i) full performance of the bond obligation or (ii) prior written consent of TOTAL E&P USA, INC. (“TOTAL”), the Surety shall (x) immediately issue a separate bond with equivalent obligation to TOTAL as obligee in the exact amount of such reduction; and (y) issue a rider to the bond reducing the bond’s amount by the amount of such separate bond.

provided, however, the effect of such rider or other instrument shall cease and become null and void in the event that the then amount of such Supplemental Bond is required by the MMS Bonding Unit to meet Buyer’s supplemental bond requirements for the applicable lease (and in such event, if requested, Seller shall consent to such termination); and

Subject to Section 2.02(d)(i) and (ii), the above described reductions in the required Collateral Amount of Collateral shall apply for as long such offsetting Supplemental Bonds are given credit to satisfy a supplemental bond obligation imposed on a Lease by the MMS Bonding Unit.

As an illustration of the above described mechanism, if the MMS Bonding Unit requires a supplemental bond in the amount of $35 million and the Buyer satisfies the obligation with Supplemental Bonds, the required Collateral Amount of Collateral will be reduced by $35 million. However, if the MMS Bonding Unit requires a supplemental bond in the amount of $35 million and the MMS Bonding Unit accepts Supplemental Bonds from Buyer in the amount of $50 million, the required Collateral Amount of Collateral will still be reduced by $35 million, unless Buyer complies with the requirements of Section 2.02(d)(i) and (ii) in which case the required Collateral Amount of Collateral will be reduced by $50 million.

(e) In order to further ensure Buyer’s Plugging and Abandonment obligations under this Agreement, Seller shall reserve at Closing an overriding royalty interest in each of the Leases in the amount equal to 7% of 8/8ths (proportionately reduced to the working interest to be assigned to Buyer in each Lease) which interest shall be free and clear of all burdens (except for the lessor’s royalty and any burdens created by, through or under Seller) and which reservation shall be contained in a form substantially similar to the Assignment of Record Title Interest shown on Exhibit “E” (collectively, the “ORRI”). The proceeds of the ORRI shall be deposited into the Cash Collateral Account (in which Seller shall have a perfected security interest). In the event that at the end of each year listed above, the Collateral Amount required as of the end of such year is greater than the sum of the amount of the Collateral and the MMS Collateral, Buyer shall provide Collateral or MMS Collateral in an amount necessary to make up the shortfall by whatever means no later than January 31st of the immediately following year. Notwithstanding anything in this Section 2.02(e) to the contrary, it is the intent of the Parties that the ORRI shall pay into the Cash Collateral Account at regular intervals to coincide with the payment of lessor’s royalties. If during a given calendar year the amount of the ORRI paid into the Cash Collateral

Account for that given calendar exceeds the Minimum Annual Funding required for that given year, the Collateral Agent shall immediately disburse to Buyer all amounts in excess of Minimum Annual Funding for that given year and thereafter all amounts paid into the Cash Collateral Account by the ORRI during such calendar year.

The following additional conditions shall apply to the provisions above regarding the ORRI and the Cash Collateral Account:

(f) The Collateral and the ORRI shall remain in effect until (i) Buyer has performed all of its obligations assumed hereunder in regard to the Plugging and Abandonment of the Properties; (ii) Buyer has a rating of Investment Grade or (iii) Buyer provides to Seller an irrevocable guaranty from an entity covering the Plugging and Abandonment (in a form reasonably acceptable to Seller (which acceptance shall not be unreasonably withheld)) provided that such entity is rated Investment Grade and (y) approved by the MMS to act as an indemnitor to provide a third-party indemnity in lieu of a supplemental bond in the amount of the guaranty to Seller, provided Buyer uses reasonable commercial efforts to ensure that the guarantor timely provides the materials necessary and requests that the MMS make a determination of financial strength and liability during the period the such guaranty is in force and effect or (z) in spite of good faith attempts to seek such approval, the guarantor is not approved by the MMS to act as an indemnitor to provide a third-party indemnity in lieu of a supplemental bond in the amount of the guaranty to Seller, it is the opinion of KPMG (or other agreed upon third party) that such guarantor meets all of the financial requirements imposed by the MMS for an indemnitor to provide a third-party indemnity in lieu of a supplemental bond in the amount of the guaranty.

In the event Buyer complies with (i), (ii) or (iii) above, the Collateral and the ORRI shall be released, the ORRI conveyed to Buyer and all funds in the Cash Collateral Account shall be transferred to Buyer. Thereafter, Buyer shall have no further obligation under this Section 2.02.

(g) Plugging and Abandonment with respect to a Property shall be deemed performed when Buyer shall submit to Seller written evidence that such Plugging and Abandonment with respect to a Property has been satisfactorily performed (which written evidence may be in the form of (i) written abandonment application of Buyer (which may

include platform reefing) that has been approved or accepted by the MMS and any applicable state agency (as applicable) and (ii) the abandonment report of Buyer (certifying performance of such approved abandonment) that has been filed with the MMS).

(h) Buyer agrees that if Buyer sells the Property to an affiliate or a third party, Buyer shall require that a provision substantially in the form of this Section 2.02 be included in any transaction selling or trading the Property to such affiliate or third party unless (i) Buyer retains the obligation to maintain the Collateral in the manner provided for under this Section 2.02 or (ii) the entity receiving the interest in the Property(ies) is rated Investment Grade. In the event an undivided interest in one or more of the Properties is sold to a purchaser which is rated Investment Grade, Buyer’s obligations under this Section 2.02 shall be proportionately reduced to the extent of the conveyed undivided interest, but only to the extent that Buyer maintains a uniform proportional interest in each of the Properties, unless the Plugging and Abandonment obligations with regard to (i) OCS-G 16549 (VK 822) and OCS-G 10942 (VK 823) or (ii) OCS-G 19931 (MC 243) and OCS-G 24282 (ROW) have been fully completed.

(i) Notwithstanding anything in this Agreement to the contrary, Buyer agrees to promptly satisfy, and to maintain in accordance with applicable laws, any and all bonding obligations or other securities which may be required of it pursuant to all applicable federal and state laws, rules and regulations as regards the Properties.

(j) In the event Buyer exercises its right under Section 1.01 to acquire the Properties in the name of Nominee, Buyer shall provide a Guaranty of the Plugging and Abandonment obligations which shall be executed and delivered to Seller at Closing in a form substantially similar to the Guaranty attached hereto as Exhibit “K” (the “Guaranty”).

(k) In the event Buyer exercises its right under Section 1.01 to acquire the Properties in the name of Nominee, Buyer shall provide a Consent to Assign and Property Control Agreement which shall be executed and delivered to Seller at Closing in a form substantially similar to the form attached hereto as Exhibit “L” (the “Consent”). Among other things, the Consent shall contain provisions which (i) limit Buyer’s ability to divest itself of (y) ownership interest in Nominee or (z) ownership of the Properties without Nominee first assigning the Properties to Buyer or without the prior written consent of Seller (which consent shall not be unreasonably withheld) and (ii) requires Nominee to assign all of its interest in the Properties to Buyer prior to Nominee becoming insolvent, being placed into receivership, or becoming the subject of an order for relief under Title 11, United States Code, which in the case of a default by Buyer, which is not cured by Buyer within thirty (30) days after Buyer receives written notice of default, stipulated damages in the amount of $5 million.

(1) the value of all Hydrocarbons in storage or in the pipelines or in transit, as of the Effective Time, that is produced from Mississippi Canyon Block 243, OCS-G-19931, such value to be the actual price received for such Hydrocarbons upon the first sale thereof to Seller’s purchaser (regardless of whether such purchaser is affiliated with Seller or not) or absent a sale, then such value shall be based upon the average market price posted for oil of similar quality and grade and for gas, the published price in Platt’s Gas Daily Henry Hubb price/mmbtu for gas of similar quality and grade in effect as of the Closing Date;

(2) the amount of all operating costs incurred and paid by or on behalf of Seller, including, (a) with respect to the period from the Effective Time until the Execution Date, as to the Viosca Knoll Block 822 Unit, covering Viosca Knoll blocks 822 and 823 (the “Virgo Unit”), any overhead charges allowable under the accounting procedure promulgated by the Council of Petroleum Accountant Societies (“COPAS”) and made part of the Virgo Unit Operating Agreement and in the case of Mississippi Canyon 243 Field (“Matterhorn”), the amount that would result if the COPAS accounting procedure for the Virgo Unit were applied to Matterhorn, (b) with respect to the period from the Execution Date until the Closing Date, all overhead charges allowable under paragraph (a) above as to the Virgo Unit and, in the case of Matterhorn, the amount as historically calculated and charged by Seller to Matterhorn in lieu of COPAS overhead, and, (c) with respect to the period from the Effective Time until the Closing Date, all capital expenditures incurred and paid by or on behalf of Seller in connection with the operation of the Properties that are attributable to the period of time after the Effective Time, including, without limitation, royalties, rentals and other charges, ad valorem, property, production, excise, severance, marketing fees as historically calculated and applied by Seller to the Properties and any other taxes (other than income taxes) based upon or measured by the ownership of the Lands or the Equipment or the production of Hydrocarbons or the receipt of proceeds therefrom, not deducted or netted from proceeds under Section 2.03(b)(2) below.;

(3) an amount equal to the sum of any Upward Adjustments provided for by Section 5.07;

(4) an amount equal to the interest calculated as the product of the lesser of (i) two and one-half percent (2.5%) per annum or (ii) the highest rate permitted by applicable law per annum and the Purchase Price attributable to the period from the Execution Date until the Closing (provided, however, if the consents shown on Schedule 3.01(l).have not been obtained within thirty (30) business days after the Execution Date, no interest shall accrue during the period that is thirty (30) business days after the Execution Date until the date such consents have been obtained);

(5) an amount equal to $5.814/mmbtu multiplied by the volume determined due and owing to Seller for the existing Gas Imbalance(s) as of the Effective Time; and

(2) the amount of gross proceeds actually received by or on behalf of Seller derived from the sale of Hydrocarbons from the Properties, net of royalties, severance taxes, and marketing costs (including, but not limited to, marketing fees, transportation, compression, gathering and processing fees, in each case consistent with past practices) deducted or paid by Seller and that are attributable to the period of time after the Effective Time;

(3) an amount equal to the sum of the Downward Defect Adjustments provided for in Section 5.05, if such amount exceeds five percent (5%) of the Purchase Price and then only to the extent of such excess;

(4) an amount equal to $5.814/mmbtu multiplied by the volume determined will be due and owing from Seller to under produced parties for the existing Gas Imbalance(s) as of the Effective Time; and

With respect to matters that can be determined as of the Closing and using the best information then available, Seller shall prepare and deliver to Buyer, for Buyer’s review, two (2) business days prior to the Closing a settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Closing Amount (defined below) and each adjustment and the calculation of each adjustment used to determine the Closing Amount. The term “Closing Amount” means the Purchase Price adjusted as provided in Section 2.03. All other adjustments to the Purchase Price shall be taken into account in the Final Settlement Statement provided in Section 9.02.

Buyer acknowledges that Seller owns an undivided interest in the Lands and Buyer agrees that the acts or omissions of the other working interest owners shall not constitute a violation of the provisions of this Section 4.01(a) nor shall any action required by a vote of working interest owners constitute such a violation so long as Seller has voted its interest in a manner which complies with the provisions of this Section 4.01(a).

(a) As used herein, the term “Good and Defensible Title” means, as to each of the Properties, ownership of leasehold, fee or royalty interests or other forms of property interests by virtue of which Seller can successfully defend against a claim to the contrary made by a third party, such that Seller (and upon Closing, Buyer) is (i) entitled to receive not less than the net revenue interest in production of oil, gas and other minerals from the wells described in Exhibit “B” throughout the life of such Property, subject to no liens, encumbrances, obligations (other than Permitted Encumbrances), (ii) is not obligated to pay costs and expenses associated with Seller’s interest greater than the working interest shown for such wells in said Exhibit “B” or (iii) not adversely affected or interfered in any material respect with the ownership of such Properties (other than Permitted Encumbrances).

(1) Lessor’s royalties, overriding royalties, reversionary interests and other burdens affecting Seller’s net revenue interest if the net cumulative effect of such burdens does not operate to reduce the interest of Seller in any Property to less than the net revenue interest set forth in Exhibit “B”;

(2) Materialman’s, mechanic’s, repairman’s, employee’s, contractor’s, operator’s, tax and other similar liens or charges arising in the ordinary course of business: (i) if they have not been filed pursuant to law or if they are liens or mortgages to be released at Closing; (ii) if filed, payment is being withheld as provided by law; (iii) if they are against a Property in which Seller owns only an undivided interest and they arise pursuant to operations governed by any agreement which disclaims the existence of

joint and several liability, then in such a proportion as such lien or charge encumbers interests other than the undivided interest of Seller; (iv) if their validity is being contested in good faith by appropriate action, and Seller agrees to indemnify Buyer from all costs and expenses relating to such lien or charge and the related action or (v) for which Seller has indemnified Buyer for such lien;

(3) All rights to consent by, required notices to, filings with, governmental entities, or other actions by governmental entities, in connection with the sale or conveyance of the Leases;

(4) Conventional rights of reassignment arising upon a decision or election by the owner of the Properties to surrender or abandon all or any portion of the Properties either by an express election or as a result of any other election where such a result arises under the applicable contract, provided such rights have not been exercised except to the extent provided in Exhibit “B”;

(5) Non-consent penalties applied against the interest of Seller arising under applicable operating agreements heretofore incurred and reflected in Exhibit “B”;

(8) The terms and conditions of all leases, servitudes, agreements, declarations, orders, instruments, contracts, documents including without limitation, the terms and conditions of any and all contracts, agreements and other matters described and assigned hereby or referred to in this Agreement or exhibits hereto insofar and only insofar as they do not operate to: (A) reduce the net revenue interest for any Lease below that set forth on Exhibit “B” for such Lease or (B) increase the working interest for any Lease above that set forth on Exhibit “B” for such Lease without a proportionate increase in the corresponding net revenue interest;

(10) Rights reserved to or vested in any municipality or governmental, statutory or public authority to control or regulate any of the Properties in any manner, and all applicable laws, rules and orders of governmental authority;

11) The existence of any and all claims, liens or other encumbrances against the Properties arising from or related to claims or litigation disclosed in Exhibit “F” and, for which Seller has indemnified Buyer; and

(12) Any third party consents to assign that have been obtained or have been waived by the holder of such third party right prior to Closing.

If, prior to the Closing, all or any portion of the Properties are destroyed by fire or other casualty of a similar nature, or shall be taken by condemnation or under the right of eminent domain (each a “Casualty Loss”), Buyer may elect: (i) to treat the Casualty Loss as a Title Defect in accordance with Section 5.04 and 5.05; or (ii) to purchase such Property notwithstanding any such destruction or taking (without reduction of the Purchase Price), in which case Seller shall, at the Closing, pay to Buyer all sums paid to Seller by third parties by reason of the destruction or taking of such Property, and shall assign, transfer and set over unto Buyer all of the right, title and interest of Seller in and to any unpaid proceeds or other payments from third parties arising out of such destruction or taking. Prior to Closing, Seller shall not voluntarily compromise, settle or adjust any amount payable by reason of any Casualty Loss without first obtaining the written consent of Buyer.

The term “Title Defect” means: (i) Seller’s net revenue interest in any of the Properties being less than the interests set forth in Exhibit “B”; (ii) Seller’s working interest in any of the Properties being more than the respective interest set forth on Exhibit “B” without a corresponding increase in net revenue interest; or (iii) the existence of any encumbrance, encroachment, irregularity, defect in or objection to Seller’s title to any Property (expressly excluding Permitted Encumbrances) that alone or in combination with other defects renders Seller’s title to such Properties less than Good and Defensible Title (including any Casualty Loss treated as a Title Defect pursuant to Section 5.02 above). As soon as practicable, but in no event after ten (10) business Days prior to Closing, Buyer shall furnish written notice to Seller, specifying objections to Seller’s title to any Properties which, in Buyer’s opinion, constitute Title Defects. Such notice of Title Defect shall be in writing and shall include: (i) a description of the Properties (or portion thereof) affected by the alleged Title Defect; (ii) the basis for determining that a Title Defect exists; and (iii) the amount by which Buyer believes the Allocated Value of the Property (as set forth on Exhibit “B”) has been diminished as a result of the alleged Title Defect. Buyer shall be deemed to have waived any Title Defects that are not asserted by the assertion date required in this Section 5.03.

If Buyer timely notifies Seller of an alleged Title Defect, Seller shall have the right, but not the obligation, to elect to cure the Title Defect or, in the alternative, reduce the Purchase Price in the manner provided in Section 5.05, and Seller shall furnish to Buyer prior to Closing written notice of its election. Such notice shall be in writing and shall state whether Seller agrees with the value attributed to the Title Defect as set forth in Buyer’s notice or, if not, the value which Seller attributes to such Title Defect. If Seller elects to reduce the Purchase Price, then the Purchase Price shall be adjusted as provided in Section 5.05. If Seller elects to cure the Title Defect, the procedure in Section 5.06 shall apply.

If Seller is unable or elects not to cure a Title Defect of which Seller has been notified properly, exclusive of casualty losses under Section 5.02(ii), then in the event the total diminution in the value of the affected Properties exceeds five percent (5%) of the Purchase Price (the “Threshold Amount”), the Purchase Price shall be adjusted by the amount of Title Defects in excess of the Threshold Amount as set forth below:

The affected Property shall be sold and conveyed to Buyer, and the Purchase Price attributable to such Property will be reduced by the value diminution attributable to such Title Defect insofar as it exceeds the Threshold Amount (the amount of any such reductions being “Downward Defect Adjustments”), which shall be determined as follows:

(i) Where Seller agrees with the value of the Title Defect as set forth in Buyer’s notice, that value shall be the amount of the Downward Defect Adjustment.

(ii) If the Title Defect is a lien, encumbrance or other charge upon a Property which is undisputed and liquidated in amount, then the Downward Defect Adjustment shall be the amount necessary to be paid to the obligee to remove the Title Defect from the affected Property; provided, however, that if the Title Defect affects more than Seller’s interest in the affected Property, then the amount of the Downward Defect Adjustment will be reduced proportionately to the extent of Seller’s interest in the affected Property.

(iii) If the value of the alleged Title Defect set forth in Buyer’s notice is in dispute then the parties shall negotiate in good faith to reach an agreed Downward Defect Adjustment amount. If the parties cannot agree on the value of the alleged Title Defect, then the Downward Defect Adjustment shall be subject to arbitration in accordance with Section 11.14.

If Buyer asserts Title Defects, the value diminution of which is in excess of the Threshold Amount, and Seller elects to cure and cures such Title Defect, such Property shall be conveyed upon Closing, and the portion of the Purchase Price attributable to such Property shall be contemporaneously paid by Buyer to Seller in the same manner and to the same extent that such Property would have been treated if the Title Defect had not been asserted. In the event Seller fails to cure any Title Defect prior to Closing, then at Closing the Buyer shall elect to either waive the Title Defect and proceed to Closing or continue to assert the Title Defect. As to those Properties where a Title Defect continues to be asserted:

(a) If Seller fails to cure a Title Defect within the one hundred and twenty (120) day period following Closing, Seller, at its option, may either (i) rescind its election to cure

such Title Defect, in which case Section 5.05 shall govern with respect to such Property; or (ii) refund the amount of the Purchase Price subject to the Title Defect and Buyer shall then reconvey the Property for which the Title Defect was not cured to Seller by executing an Assignment, Bill of Sale and Conveyance, substantially identical in form and substance as Exhibit “E”, and neither Buyer nor Seller shall have any further obligation respecting the purchase or sale of such Property.

(b) In no event shall Seller’s liability for uncured Title Defects exceed the Allocated Value of the Property against which such Title Defect is asserted and then only to the extent the total amount of Title Defects exceeds the Threshold Amount.

If there is any inaccuracy that results in Seller owning an increased net revenue interest in the Properties, the party discovering such inaccuracy shall immediately notify the other party of such inaccuracy, and the Purchase Price shall be increased in proportion to the increase in the net revenue interest multiplied by the associated Allocated Value (“Upward Adjustment”).

Upon discovery of Material Environmental Conditions as defined below, but only to the extent that the cost to remediate such conditions to lawfully acceptable levels will exceed, in the aggregate, as to Buyer’s share, five percent (5%) of the Purchase Price, but in no event not later than twenty (20) business days prior to the Closing, Buyer shall immediately notify Seller of the nature of such conditions and shall furnish Seller with Buyer’s basis for the assertion of such conditions along with available data in support thereof. Subject to Section 10.01(d), in the event Buyer has properly notified Seller of one or more Material Environmental Conditions, Seller, at its sole discretion, shall select one of the following options:

(a) Seller shall remedy the Material Environmental Conditions at its own expense and to the satisfaction of the appropriate governmental authority prior to the Closing or as soon thereafter as is reasonably practicable; or

(b) Seller shall reduce the Purchase Price by an amount equal to the cost of the remediation of the Material Environmental Conditions, as determined by the third party contractor to be mutually agreed upon by Buyer and Seller; or

(c) Seller shall exclude the affected Property from the sale and reduce the Purchase Price by an amount equal to the Allocated Value of the affected Property as set forth on Exhibit “B”; or

(d) Seller shall indemnify and hold Buyer harmless from any and all Losses arising from the Material Environmental Condition.

“Material Environmental Condition” means a condition, excluding any condition relating to Plugging and Abandonment, that existed prior to the Effective Time but only to the extent it remains in existence after the Effective Time, with respect to the air, land, soil, surface, subsurface strata, surface water or sediments which causes a Property to be subject to remediation under Environmental Laws in effect as of the Effective Time.

Any Material Environmental Condition that is not disclosed in writing by Buyer to Seller prior to twenty (20) Business Days before the Closing shall conclusively be deemed waived by Buyer, and Buyer hereby expressly assumes such liability along with liability for any other environmental condition affecting the property.

At the Closing the following events shall occur, each being a condition precedent to the others and each being deemed to have occurred simultaneously with the others.

(a) Seller shall execute, acknowledge and deliver to Buyer, an Assignment, Bill of Sale and Conveyance, substantially identical in form and substance as the instrument attached hereto as Exhibit “E”, on an “AS IS - WHERE IS” basis, with a limited warranty of title by, through or under Seller, but not otherwise, of all of Seller’s right, title and interest in the Properties (including MMS forms of assignment) for each of the Leases, six (6) original counterparts of (i) MMS Form 150, (ii) an Exhibit “A” to such form being an Assignment of Record Title Interest, substantially identical in form and substance as the instrument attached as Exhibit “E” (with both the MMS Form 150 and the Exhibit “A” being executed), (iii) any necessary conveyances for the Pipeline Properties, which together will assign the Leases and the Pipeline Properties to Buyer in accordance with the terms of this Agreement and letters-in-lieu and such notices as are reasonably necessary to direct purchasers of production from such Leases to remit the proceeds of such production to Buyer and (iv) the CG 1340 Bill of Sale and CG 1258 Application for Initial Issue, Exchange, or Replacement of Certificate of Documentation required by the U.S. Coast Guard.

As regards to such retained accounting records, Seller shall make available to Buyer such records for inspection and copying, at Buyer’s expense, during normal business hours. From time to time as requested by Seller, Buyer shall make such files, records and data which it takes possession of available to Seller for inspection and copying during normal business hours, at Seller’s expense, together with such additional files, data and records of Buyer as may be reasonably requested by Seller in order to pursue any claims, obligations and disputes relating to the Properties. The files and records shall be made available to Buyer the same format and condition as they are held by Seller as of the date of this Agreement.

To the extent Seller is presently involved in the administration of the Properties, Seller shall retain the obligation and responsibility for the administration of the Properties for the period ending on the Closing Date.

The date upon which such Agreement is reached or upon which the Adjusted Purchase Price is established, shall be herein called the “Final Settlement Date.” In the event that (i) the

Adjusted Purchase Price is more than the Closing Amount, Buyer shall pay to Seller in immediately available funds the amount of such difference, or (ii) the Adjusted Purchase Price is less than the Closing Amount, Seller shall pay to Buyer in immediately available funds the amount of such difference to Buyer.

Any adjustment required pursuant to this section shall be in accordance with the principles set forth in this Agreement as regards such adjustment.

Seller shall be entitled to all amounts payable to it with respect to reimbursement of prepaid expenses, and settlements or judgments of claims, obligations or disputes related to the Properties (including take-or-pay claims) which arise, accrue or relate to events occurring prior to the Effective Time, including but not limited to those claims shown on the attached Exhibit “I”, regardless of when such amount is finally paid, and Seller hereby expressly reserves all right with respect thereto.

Buyer shall pay all applicable transfer, sales and use taxes and associated interest, penalties and all other costs which Buyer has directly contracted to pay occasioned by the sale of the Properties and all documentary, filing and recording fees required in connection with the filing and recording of any assignments. Buyer agrees to indemnify Seller from and against all losses, obligations, liabilities, costs and expenses (including, without limitation, attorney fees and cost of trial and appeal) associated with all applicable transfer, sale and use taxes and associated interest and penalties, if any, occasioned by the sale of the Properties.

The two (2) arbitrators so chosen shall select a third arbitrator within thirty (30) Days after the second arbitrator has been appointed.

provided that, all potential arbitrators shall meet the qualification requirements of this Article 18. With respect to arbitrators selected using the procedures set out in R-13.b or R-15.c, if any, the AAA shall submit lists to the parties until an arbitrator is selected and shall not have the power to make an appointment other than through the exchange of lists. The parties each shall pay one-half of the compensation and expenses of the arbitrators. All arbitrators must (a) be neutral persons who have never been officers, directors, employees, or consultants or had other business relationships with the parties or any of their affiliates, officers, directors or employees, and (b) have not less than seven (7) years recent experience in the U.S. oil and gas industry relevant to the matters in dispute. The hearing will be conducted in Houston, Texas, and commence as soon as practicable after the selection of the third arbitrator. The parties and the arbitrators should proceed diligently and in good faith so that the award can be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators shall be binding on and non-appealable by the parties. The arbitrators shall have no right or authority to grant or award indirect, consequential, punitive or exemplary damages of any kind.

All exhibits and schedules attached to or referred to in this Agreement are incorporated into and made a part of this Agreement.

Whenever a statement regarding the existence (or absence) of any fact in this Agreement is qualified by a phrase such as “to the best of such party’s knowledge” or “known to such party,” Buyer and Seller intend that the only information to be attributed to such party is information actually known to (i) the person in the case of an individual, or (ii) in the case of a corporation, a current officer who devotes, or has devoted, substantial attention to matters of such nature during the ordinary course of his employment during the last twenty-four (24) months. Unless otherwise specifically provided in this Agreement, no party is represented or obligated to have undertaken a separate investigation in connection with the transaction contemplated in this Agreement to determine the existence (or absence) of any statement or representation qualified by a phrase such as “to the best of such party’s knowledge” or “known to such party.”

IN WITNESS WHEREOF, Buyer and Seller have executed this Agreement on the day and year first above written.
