Initial Incentive Pool Employees and Allocations. Schedule 6.10 to the Purchase Agreement is hereby deleted and replaced in its entirety by Schedule 6.10 attached hereto.

Separation and Severance Agreement. Pursuant to Section 6.1 of the Purchase Agreement, Buyer hereby consents to TexCo’s entry into that certain Separation Agreement and General Release, as amended, attached hereto as Exhibit A, (the “Shareholder Termination Agreement”). TexCo and the Seller Parties represent and warrant to Buyer that all of the vested and unvested shares of TexCo previously issued to the counterparty to such Shareholder Termination Agreement have been redeemed and cancelled by TexCo as contemplated by such Shareholder Termination Agreement and are no longer issued or outstanding as of the date hereof. All amounts contemplated to be paid by TexCo or any of its affiliates, including future conditional payments, under the Shareholder Termination Agreement shall be reflected as liabilities in the calculation of Estimated Closing Working Capital and Closing Working Capital (whether or not such amounts would otherwise constitute current Liabilities in accordance with Applicable Accounting Standards) to the extent such amounts remain unpaid as of the Closing.

Certain Other Severance Arrangements. In addition to the matters subject to the Shareholder Termination Agreement, the parties hereto understand and acknowledge that the employment of certain employees of TexCo and its subsidiaries has been or may be terminated (whether before or after the

Up to $200,000 of post-Closing Seller-Paid Severance Costs relating to the person listed on Annex A-3 will be funded using Rescinded Retention Awards (as defined below) in accordance with Section 7 and Annex B-2 (the portion of Seller-Paid Severance Costs so funded, the “Offset Severance Costs”).

The foregoing allocation of the Agreed Severance Costs is to be reflected through the Closing Working Capital adjustment as follows: (i) any Buyer-Paid Severance Costs or Offset Severance Costs in each case that remain unpaid as of the Closing shall not be reflected as liabilities in the calculation of Estimated Closing Working Capital and Closing Working Capital, (ii) the calculation of Estimated Closing Working Capital and Closing Working Capital shall be increased (i.e. resulting in a positive adjustment) in an amount equal to any Buyer-Paid Severance Costs that are or have been paid by TexCo or one of its subsidiaries as of or prior to the Closing and (iii) any Seller-Paid Severance Costs that have not been paid by TexCo or its subsidiaries as of the Closing shall be reflected as liabilities in the calculation of Estimated Closing Working Capital and Closing Working Capital (whether or not such amounts would otherwise constitute current Liabilities in accordance with Applicable Accounting Standards). For the avoidance of doubt, the amounts used in the calculation of Estimated Closing Working Capital for purposes of the Closing will be subject to adjustment pursuant to Section 1.4 of the Purchase Agreement.

Section 10.1(d) of the Purchase Agreement is hereby amended by inserting “Seller-Paid Severance Costs,” immediately after the word “any” appearing at the beginning thereof.

Retention Pool, Incentive Pool. Notwithstanding anything to the contrary in the Purchase Agreement, any person whose employment with TexCo or one of its subsidiaries is terminated at or prior to the Closing (or who has failed to enter into or has rescinded their offer letter with Buyer providing for Employment-Related Retention as of the Closing) and any person or category of persons identified on Annex A-1 hereto (whether or not terminated at or prior to Closing) will not receive any Employment-Related Retention and will not be an Incentive Pool Employee (unless otherwise determined in accordance with Section 6.10(a) of the Purchase Agreement). Annex B-1 sets forth certain Employment-Related Retention Awards that were never actually awarded or which have been rescinded or forfeited pursuant to the foregoing sentence (collectively, the “Rescinded Retention Awards”). None of Parent, Buyer or their Affiliates shall be obligated to pay or issue any of the Rescinded Retention Awards. The amounts that otherwise would have constituted Rescinded Retention Awards will be reallocated as provided in Annex B-2. Notwithstanding Section 6.9(g) of the Purchase Agreement or anything else to the contrary, Buyer and its Affiliates will not be obligated to pay the Rescinded Retention Awards and the amount of the Rescinded Retention Awards shall not increase the Incentive Pool except as set forth on Annex B-2. Section 6.9(g) is hereby amended to reflect that the grants of Employment-Related Retention will include an aggregate of $8,940,000 of restricted cash (rather than $9,140,000) and an aggregate of $11,614,000 of restricted Parent Common Stock (rather than $12,089,000).

Bonus Payments. Notwithstanding Section 6.9(i) of the Purchase Agreement, Seller and Buyer agree that a certain portion of accrued bonuses will be paid in August 2016 (rather than within 75 days after Closing), as more fully described on Annex C.

James Baker Share Transfer. Pursuant to Section 6.1 of the Purchase Agreement, Buyer consents to TexCo’s entry into that certain Waiver of and Addendum to the Simmons & Company International Second Amended and Restated Shareholders’ Agreement in the form previously approved by Buyer, subject to the transferees’ concurrent execution of Owner Support Agreements and Equity Consideration Restricted Stock Agreements in the form previously approved by Buyer.

ScotCo Dividend. The distribution by ScotCo of £5,250,000 pursuant to a previously declared dividend, as contemplated by Section 6.18 of the Purchase Agreement, shall be subject to the availability of distributable profits and to ScotCo’s compliance with applicable regulatory capital requirements and may be reduced by the directors of ScotCo in order to ensure satisfaction of such requirements.

Amendment to TexCo Shareholders’ Agreement. Notwithstanding Section 6.17 of the Purchase Agreement or Schedule 6.17 to the Purchase Agreement, the parties hereto agree that the Second Amended and Restated Shareholders’ Agreement, dated June 30, 2011, by and between TexCo and the TexCo Holders, as amended by that certain Amendment No. 1 to the Second Amended and Restated Shareholders’ Agreement, dated June 30, 2012, shall not be terminated, and shall instead be amended and restated, with TexCo being removed as a party automatically as part of the Pre-Closing Restructuring.
