(a) The Parties acknowledge that Buyer caused an Affiliate of Intertek Group, PLC (“ Intertek ”) to measure the volumes of (i) Onsite Inventory (as defined in Exhibit G-2 —Hydrocarbon Inventory Measurement Procedures) contained in some, but not all, tanks at the Refinery on May 31, 2016 and (ii) the WPC Inventory contained in tanks (but not pipelines) on May 31, 2016, and that in each case those measured volumes are correctly stated in Exhibit G-1 —May EOM Inventory.

(b) The Parties also acknowledge that they have agreed (for purposes of this Section 5.7 , Section 8.1(c) and Section 8.2(b) only) as to (i) the volumes of Onsite Inventory that were not physically measured on May 31, 2016, (ii) the volumes of the WPC Inventory that were not physically measured on May 31, 2016, and (iii) the volumes of Offsite Inventory on May 31, 2016 and that in each case those agreed volumes of unmeasured Onsite Inventory, Offsite Inventory and WPC Inventory are correctly stated on Exhibit G-1 .

(e) Buyer shall have the option, but not the obligation, to have the Onsite Inventory and the WPC Inventory measured and sampled by a mutually agreeable independent inspector (the “ Field Inspector ”) on a date that is the first or second day preceding the Closing Date (the “ Inventory Measurement Date ”). Buyer and Seller shall use their commercially reasonable efforts to cause Intertek to be the Field Inspector. The Field Inspector shall measure and sample the Onsite Inventory and WPC Inventory (including tank sludge) as of the Inventory Measurement Date at the respective locations of the Hydrocarbon Inventory on the Inventory Measurement Date; provided, however , that notwithstanding anything herein to the contrary,

45

(i) the volumes of all Onsite Inventory in process units and pipeworks shall not be measured or valued by the Field Inspector or the Parties, (ii) the volumes of all Hydrocarbon Inventory in transit, whether inbound or outbound, by pipeline (including line fill), railcar or truck shall be determined as set forth on Exhibit G-2 and shall not be measured by the Field Inspector or included in the Field Inspector Report but shall instead be validated by bills of lading (in the case of railcar or truck loads) or meter tickets for pipeline batches, and (iii) all crude tank and other volume compositions shall be determined as set forth on Exhibit G-2 .

The fees and expenses of the Field Inspector shall be borne equally by Seller and Buyer.

The Closing Inventory Statement shall be in substantially the same format as Exhibit G-1 to the extent practical.

(h) No later than 20 days following its receipt of the Closing Inventory Statement, Buyer shall give Seller notice of (i) its acceptance of the Closing Inventory Statement (including the Closing Inventory Value) or (ii) specific and reasonably detailed objections to the Closing Inventory Value and/or (to the extent expressly permitted in Exhibit G-2 ) the volumes set forth in the Closing Inventory Statement, and Buyer shall be deemed to have agreed with all matters set forth in the Closing Inventory Statement that are not so objected to.

If Buyer gives such notice to Seller of Buyer’s objection within such 20-day period, and Buyer and Seller are unable to resolve the issues in dispute within 10 days after delivery of such notice of objection, each of Buyer’s and Seller’s positions on the remaining items in dispute with respect to the computation of the Closing Inventory Value will be submitted to an independent and qualified party mutually selected by the parties (the “ Dispute Inspector ”) such as an accounting firm or independent inspector, for final resolution. The fees and expenses of the Dispute Inspector shall be borne equally by Seller and Buyer.

46

(i) If the total Closing Inventory Value (as finally determined pursuant to this Section 5 .7 ) minus the total May EOM Inventory Value (such difference, the “ Inventory Balance ”) is less than zero, then, subject to Section 8.1(c) , Buyer may bring a Claim for Indemnification under Section 8.2(b) for the absolute value of the Inventory Balance (an “ Inventory Claim ”).

(j) Each Party agrees that it shall not take any actions with respect to the operations books and records, accounting books and records, policies and procedures of itself or its Affiliates that would obstruct or prevent the preparation of an accurate Closing Inventory Statement as provided in this Section 5.7 .

Seller agrees to use commercially reasonable efforts to assist Buyer with any reasonable request in Buyer’s efforts to obtain such title policies; provided that Seller shall not be obligated to incur any costs or expenses in connection with such assistance.

49

Section 6.3 Employee Matters .

(a) Schedule 6.3(a) sets forth (i) the name and title of certain Employees employed as of the Execution Date (the “ Specified Employees ”), (ii) the Employee Obligations that would arise in connection with the termination of each such Specified Employee and (iii) Buyer’s anticipated categorization of such Specified Employee as a Continued Employee, a Transitional Employee or a Non-Continued Employee. Each Employee that is not a Specified Employee shall be deemed a Continued Employee for the purposes of this Section 6.3 . Subject to applicable Law and all agreements and other arrangements with the Specified Employees, not fewer than five Business Days prior to the Closing Date, Buyer shall provide Seller with a schedule (the “ Employee Severance Schedule ”) of the Specified Employees to whom Buyer or its Affiliate will provide continuing employment (whether at Buyer, an Affiliate of the Buyer or the Companies), subject to the employment practices and policies of Buyer and its Affiliates (the “ Continued Employees ”), a list of Specified Employees whom Buyer will provide continuing employment during a six month transitional period following the Closing (the “ Transitional Employees ”) and a list of Specified Employees whom Buyer will not provide continuing employment for the period after the Closing (the “ Non-Continued Employees ”); provided , however , in each case the number of employees identified as Transitional Employees and Non-Continued Employees on the Employee Severance Schedule shall not materially differ from the number of employees identified as Transitional Employees and Non-Continued Employees on Schedule 6.3(a). The employment of the Continued Employees with Buyer, an Affiliate of Buyer or the Companies (A) shall be effective or shall continue, as applicable, as of the Closing Date, (B) shall provide for a substantially comparable pay rate as earned by the Continued Employee immediately prior to the Closing through December 31, 2016, and (C) shall offer such employee continued employment in his or her current position or a position with materially comparable duties (subject to Buyer’s, its Affiliate’s, the Companies’ ability to terminate any employee at any time and for any reason). In addition, following the Closing, the Continued Employees will continue to participate in all Company Benefit Plans on the same basis and the same extent as they participated prior to the Closing, unless and until Buyer determines to amend, modify, terminate, substitute or replace such plans, which Buyer may do in its discretion. Seller shall use its commercially reasonable efforts to assist Buyer with Buyer’s (or the Companies’ immediately following Closing) entry into employment agreements with any Continued Employee.

(b) Prior to the Closing Date, and following the adoption of the amendment and restatement of the Company Severance Plan (in form and substance consistent with the terms of this Agreement and acceptable to Buyer) by Refining Company, Seller and the Companies shall take all action necessary to transfer the sponsorship of the Company Severance Plan to Refining Company such that all obligations and payments thereunder will be the responsibility of and will be paid by the Companies and not by Seller. Prior to the Closing Date, following the receipt of the Employee Severance Schedule, the Companies shall terminate the employment of all Non-Continued Employees. Seller will use commercially reasonable efforts to cause all employment agreements entered into between Seller or a Company, on the one

50

hand, and Seller’s or a Company’s employees, on the other hand, providing services to the Companies to be terminated and for such employees to execute and deliver a release that is acceptable to Buyer in its reasonable discretion in exchange for the payment of the applicable Employee Obligations. At Closing or as soon as reasonably practicable thereafter, the Companies shall pay to each Non-Continued Employee and each Transitional Employee that has delivered a release that has become effective and non-revocable ((i) as provided by the Company Severance Plan (as amended prior to Closing), with respect to such Employees that do not have an employment agreement or (ii) that is reasonably acceptable to Buyer, with respect to such Employees that have an employment agreement) an amount equal to the Employee Obligations for each such Employee, by check or direct deposit in accordance with customary payroll pay procedures, which amounts for the Transitional Employees will take the form a transaction bonus. With respect to any Non-Continued Employee or Transitional Employee (A) that does not have an employment agreement and has not delivered the release provided for in the Company Severance Plan (as amended prior to Closing) or such Transitional Employee’s transaction bonus agreement, as applicable, then on December 31, 2016, Buyer shall pay to Seller an amount equal to the Employee Obligations of such Employee as set forth on Schedule 6.3(a), and (B) that has an employment agreement and has not delivered a release reasonably acceptable to Buyer, then Buyer shall pay to Seller on the earlier of (1) the date of Seller’s payment of Employee Obligations to such Employee, the amount of Employee Obligations actually paid by Seller to such Employee and (2) December 31, 2016, the amount of the Employee Obligations for such Employee.

(c) To the extent that any Continued Employee becomes eligible to participate in any Employee Benefit Plans or programs that Buyer or its Affiliates or a Company maintains or implements after the Closing (each a “ Buyer Benefit Plan ”), then for all purposes (including determining eligibility to participate and vesting under plans), service with a Company shall be treated as service under such Buyer Benefit Plan in as similar a manner as practicable; provided , however , that notwithstanding the foregoing, such service need not be recognized as benefit service (A) under any Buyer Benefit Plan which is a qualified defined benefit pension plan or (B) to the extent that such recognition would result in any duplication of benefits.

(d) From and after the Closing, the Companies will be solely responsible for all obligations and benefits under the Company Benefit Plans (excluding any such plan maintained by an ERISA Affiliate that is not one of the Companies or a subsidiary thereof) and all employment agreements entered into by the Companies with any Employees of the Companies, and Seller shall have no liability in connection therewith, except as otherwise provided in this Agreement. For the avoidance of doubt, the Buyer shall not be responsible for any employment agreements entered into between Seller and any Employee, except with respect to the payments specified in Section 6.3(b) . Buyer shall pay to each Continued Employee whose employment is terminated by Buyer, its Affiliate or a Company within 12 months of the Closing, a severance benefit package equivalent to that which would have been provided to such individual upon termination by Company under the Company Severance Plan, subject to the terms and eligibility condition of such plan and provided that such Continued Employee is not entitled to any other severance payment whether pursuant to an employment agreement or otherwise.

51

(e) Buyer acknowledges that, except as otherwise provided in this Agreement, Seller will not pay any performance or other bonuses to any Employees for any portion of the year in which the Closing occurs and that any performance or other bonuses for the year in which the Closing occurs will be the responsibility of the Companies (or of the Buyer or its Affiliates), which bonus amounts, if any, Buyer may determine in its sole discretion, subject to the terms of any applicable employment agreements, and, for the avoidance of doubt, such bonuses will not constitute Employee Obligations hereunder.

(f) After the Closing, Buyer shall ensure that neither Company shall, at any time prior to 90 days after the Closing Date, effectuate a “plant closing” or “mass layoff” as those terms are defined in the WARN Act. The Company shall provide to Buyer, on the Closing Date, a list of all employees terminated by a Company in the 90-day period immediately prior to the Closing Date.

(g) Buyer will cause the Limited Liability Company Agreement and Pipeline Company’s limited liability company agreement to contain indemnification provisions effective for not fewer than six years after the Closing for the benefit of any of the Companies’ members, directors, officers, agents and employees (“ Covered Persons ”) which are at least as favorable in all material respects to the Covered Persons as compared to current provisions regarding indemnification contained in the Limited Liability Company Agreement and the limited liability company agreement of Pipeline Company, as the case may be.

(h) The provisions of this Section 6.3 (other than Section 6.3(g) ) are for the sole benefit of the Parties and nothing herein, express or implied, is intended or shall be construed to confer upon or give to any Person (including any Employee), other than the Parties and their respective permitted successors and assigns, any legal or equitable or other rights or remedies under or by reason of any provision of this Agreement. Nothing contained herein, express or implied: (A) shall be construed to establish, amend, or modify any benefit plan, program, agreement or arrangement (including any Employee Benefit Plan); (B) shall alter or limit Buyer’s or any Company’s ability to amend, modify or terminate any benefit plan, program, agreement or arrangement (including any Employee Benefit Plan); or (C) is intended to confer upon any current or former employee of any Company any right to employment or continued employment for any period of time by reason of this Agreement, or any right to a particular term or condition of employment.

(i) With respect to each Non-Continued Employee and Transitional Employee, during the 12 month period following the termination of such Non-Continued Employee’s and Transitional Employee’s employment with a Company, Buyer may not, directly or indirectly, without the prior written consent of Seller, solicit for employment or hire any Non-Continued Employee or Transitional Employee, except for offers of employment made pursuant to a general solicitation of employment to the public or the industry.

(j) On the date that is six months following the Closing Date (the “ Transition Date ”), Buyer shall deliver to Seller a schedule setting forth each Transitional Employee and if such Transitional Employee is still employed by the Companies on the Transition Date or, if such Transitional Employee is not still employed by the Companies on the Transition Date, the date of termination of such Transitional Employee.

Seller shall have 20 days following the date of delivery of the draft Tax Return to notify Buyer in writing of either (A) any objection to such draft Tax Return or (B) Seller’s approval of the draft Tax Return. If Seller fails to provide written notice to Buyer within such twenty-day time period, Seller shall be conclusively treated as having approved of such Tax Return for all purposes hereunder. In the event Seller timely notifies Buyer of any objection with respect to a draft Tax Return (“ Objection Notice ”), Buyer shall consider in good faith Seller’s comments to such draft Tax Return. Buyer and Seller shall attempt in good faith to resolve all disputed items and amounts. If Buyer and Seller are unable to resolve any disagreement within 30 days of Buyer’s receipt of the Objection Notice, the unresolved disputes shall be referred to the Accountants for resolution in accordance with Section 6.4(a)(ii) ; provided , however , that in the event that any disputed items cannot be resolved by the Due Date for filing the applicable Tax Return, the applicable Tax Return shall be filed by such Due Date reflecting Buyer’s position with respect to such disputed items and shall, if necessary, be amended promptly after resolution of the dispute to reflect such resolution. Buyer shall deliver to Seller a complete and accurate copy of each such Tax Return prepared and filed by Buyer pursuant to this Section 6.4(a)(i) within 15 days of filing.

(ii) Buyer and Seller shall use commercially reasonable efforts to cause the Accounting Firm to resolve all remaining disagreements identified in any Objection Notice as soon as practicable, but in any event shall direct the Accounting Firm to render a written determination within 60 days after its retention. The Accounting Firm shall consider only those items and amounts (and any substantiating documentation from Buyer and Seller in connection therewith) that are identified as the items in dispute. In resolving any disputed item, the Parties will direct the Accounting Firm not to assign a value to any item greater than the greatest value for such item claimed by either Party or less than

53

the smallest value for such item claimed by either Party. The Accounting Firm’s determination of the disputed items shall be made based solely on substantiating documentation submitted by Buyer and Seller ( i.e. , not on independent review), the applicable definitions set forth herein, and an analysis that is consistent with and in accordance with the methodologies and principles contemplated herein. The determination of the Accounting Firm shall be conclusive and binding upon Buyer and Seller, and shall not be subject to appeal or further review absent manifest error. The Parties shall promptly comply with all reasonable requests by the Accountant for information, books, records and similar items. The costs and expenses of the Accounting Firm shall be borne 50% by Buyer, on the one hand, and 50% by Seller, on the other hand.

(iv) Unless otherwise required by applicable Law, Seller will not file or cause to be filed any amended Tax Returns for the Companies for any Pre-Closing Tax Period or Straddle Period without the prior written consent of Buyer, which consent will not be unreasonably withheld, conditioned, or delayed.

After the Closing, until expiration of the statutes of limitation applicable for all Pre-Closing Tax Periods and Straddle Periods, Seller and Buyer (and Buyer shall cause the Companies and their respective Affiliates to) reasonably cooperate with each other, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of any Tax Returns pursuant to Section 6.4(a) and any Tax Proceeding. In such regard, each Party shall, and shall use reasonable efforts to cause its Affiliates to, provide to the other Party such cooperation and information as any of them may reasonably request in filing any Tax Returns (including any reporting required pursuant to Section 6043 of the Code and the Treasury Regulations promulgated thereunder) or any Tax Proceeding, including making its employees reasonably available on a mutually convenient basis at its cost

(iii) Seller shall keep Buyer reasonably informed of the progress of any Tax Proceeding under Seller’s sole control pursuant to Section 8.4 .

(iv) Buyer shall have the right, at its own expense, to control and make all decisions taken in connection with any Tax Proceeding regarding a Straddle Period; provided , however , that if the results of any such Tax Proceeding would reasonably be expected to result in any liability under Section 8.2 for Seller in excess of $25,000, then Buyer shall not settle any such proceeding without Seller’s prior written consent, which consent may not be unreasonably withheld, conditioned or delayed, and Seller shall, at its own expense, have a right to participate in the defense and settlement of any such Tax Proceeding.

Each Party will notify the other if it receives notice that the IRS proposes any allocation that is different from the allocation contemplated in this this Section 6.4(i) ; provided , however , that the Parties acknowledge and agree that (i) Buyer’s cost for the Assets may differ from the total amount allocated under this Section 6.4(i) to reflect the inclusion in the total cost of items (for example, capitalized acquisition costs) not included in the amount so allocated, (ii) the amount realized by Seller may differ from the total amount allocated under this Section 6.4(i) to reflect transaction costs that reduce the amount realized for federal income tax purposes, (iii) nothing contained herein shall prevent Buyer or Seller from settling any proposed deficiency or adjustment by any Taxing Authority based upon or arising out of the Allocation Schedule, and (iv) neither Seller nor any of their Affiliates nor Buyer or any of its Affiliates will be obligated to litigate any challenge to such allocation of the Purchase Price by any Taxing Authority.

57

(b) From and after the Execution Date until the second anniversary of the Execution Date, each Seller shall maintain in confidence, shall cause its Affiliates to maintain in confidence and shall cause its and their respective Representatives to maintain in confidence, any written, oral or other information relating to the Companies, the Assets or their respective businesses, except that the requirements of this Section 6.5(b) shall not apply to the extent that (i) any such information is or becomes generally available to the public other than as a result of disclosure by Seller or its Affiliates or any of Seller’s or Seller’s Affiliates’ respective Representatives in violation of this Agreement, (ii) any such information is requested or required by applicable Law or a Governmental Authority to be disclosed (including any report, statement, testimony or other submission to such Governmental Authority), (iii) any such information is requested or required to be disclosed in connection with any Proceeding or in any dispute, in each case, with respect to this Agreement (including in response to any summons, subpoena or other legal process or formal or informal investigative demand issued to the disclosing Party in the course of any Proceeding) or (iv) any such information is or has been obtained by Seller or its Affiliates or Seller’s or its Affiliates’ respective Representatives, in each case, from and after the Closing on a non-confidential basis and from a source (other than Seller, the Companies, Buyer or any of their respective Affiliates or their respective Representatives) that is not known to be bound by a confidentiality agreement with respect to such information. If Seller or any of its Affiliates or any of Seller’s or Seller’s Affiliates’ respective Representatives becomes legally compelled by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar judicial or administrative process to disclose any information described in this Section 6.5(b) , Seller shall, or shall cause its Affiliate or the applicable Representative to, unless prohibited by Law, provide Buyer with prompt prior written notice of such requirement (including any report, statement, testimony or other submission to such Governmental Authority) and, to the extent reasonably practicable, use commercially reasonable efforts to cooperate with Buyer, at Buyer’s sole cost and expense, to obtain a protective order or similar remedy to cause such information not to be disclosed; provided , however , that, in the event that such protective order or other similar remedy is not obtained, Seller shall, or shall cause its Affiliate or the applicable Representative to, furnish only that portion of such information that has been legally compelled, and shall, or shall cause its Affiliate or the applicable Representative to, exercise its commercially reasonable efforts to obtain assurance that confidential treatment will be accorded such disclosed information.

Notwithstanding anything to the contrary herein, without satisfying the other obligations of this Section 6.5 , Seller may disclose Confidential Information to the extent disclosure is requested or required in connection with routine audits or examinations by, or blanket document requests from, a regulatory or governmental entity that does not specifically target the Companies.

(c) Without intending in any way to limit the remedies available to Buyer, Seller hereby acknowledges that the breach, or attempted or threatened breach, of the provisions of this Section 6.5 by it will result in immediate and irreparable harm to Buyer and that damages at law will not be an adequate remedy for Buyer, and further acknowledges and agrees that if such Seller breaches any of the covenants contained in this Section 6.5 , Buyer may seek injunctive relief in any court of competent jurisdiction to restrain the breach or the threatened breach of, or otherwise specifically to enforce, any of such covenants. Such injunctive relief shall be in addition to, and not in lieu of, any other remedies at law or in equity available to Buyer.
