We look forward to working with you.  In consideration of the foregoing, and for other good and valuable consideration the sufficiency and receipt of which is mutually acknowledged, the parties hereto agree as follows:  1. Nominations to the Board. Concurrently with the execution of this letter agreement, the Board has increased the size of the Board from ten to twelve directors. The Company hereby agrees to include the Saddle Point Designees on the slate of nominees to be recommended by the Board in the Company’s proxy statement and on its proxy card relating to the Company’s 2020 annual meeting of stockholders (including any adjournments or postponements thereof, the “2020 Annual Meeting”), subject to the Saddle Point Designees (i) providing the Company with all information regarding the Saddle Point Designees that the Company is entitled to receive from all other directors regarding each of them and is required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission (the “SEC”) and (ii) executing all documents required to be executed by directors nominated for election at the 2020 Annual Meeting, such documents to be in substantially the same form as documents executed and provided by all other directors in connection with the 2020 Annual Meeting (it being understood that each of the Saddle Point Designees shall have a ten day period to cure any failure to comply with clauses (i) or (ii) above, which ten day period shall commence upon receipt by such applicable Saddle Point Designee of a detailed notice from the Company specifying in detail any such failure).  

Saddle Point Management, L.P. March 26, 2020 Page 2  9986/48254-001 CURRENT/115004776v10 US-DOCS\114747541.7 2. Power and Authority. Each of the undersigned parties represents that (i) it has the due power and authority to enter into this letter agreement and perform its obligations hereunder and that the execution and delivery of this letter agreement constitutes a valid and binding obligation and agreement (except to the extent enforceability may be limited under applicable bankruptcy, insolvency or similar laws affecting creditors rights and to general principals of equity), and (ii) the execution, delivery and performance by such party shall (A) not violate or conflict with any law, rule, regulation, judgment, order, decree or similar process, and (B) not result in any breach or violation or constitute a default or acceleration of default (in each case, whether with the lapse of time, notice or otherwise) under or pursuant to any organizational document or material contract to which it is a party or by which it is bound. SPM represents and warrants that (x) Maxima Fund beneficially owns, directly or indirectly, an aggregate of 1,586,240 shares of the common stock, par value $0.01 per share, of the Company (the “Common Stock”) and such shares of Common Stock constitute all of the Common Stock beneficially owned by Saddle Point and the Saddle Point Affiliates (as defined below) or in which Saddle Point or the Saddle Point Affiliates have any interest or right to acquire, whether through derivative securities, voting agreements or otherwise (for the avoidance of doubt, the 1,586,240 shares of Common Stock excludes shares held by entities that are not controlled affiliates of SPM), and (y) SPM has sole voting power over such shares of Common Stock and no other person or Group (as such term is defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) has any voting power over such shares of Common Stock.   3. Confidentiality. The Company acknowledges that the Saddle Point Designees may, including through one-on-one conversations, communicate confidential information obtained in each of their respective capacities as a director of the Company (other than information whose provision would reasonably be expected to pose a conflict of interest) to SPM’s officers, employees, and SPM’s external counsel or other third-party advisors with a duty to keep such information confidential, in each case, in accordance with and subject to a confidentiality agreement, which SPM shall enter into with the Company (the “Confidentiality Agreement”), dated as of the date hereof, the form of which is attached as Exhibit A hereto.  4. Certain Confirmations. This letter agreement confirms that, once elected to the Board, each of the Saddle Point Designees will be entitled to the same compensation, director indemnity and insurance and other benefits as are accorded to the other non-employee directors of the Company, after accounting for their respective roles as members of committees of the Board. Except to the extent reasonably necessary to comply with applicable law, the Company confirms that it will not alter or adopt any its existing policies or its bylaws in a manner that would interfere with the purpose of this letter agreement. 5. Nominations to the Board at 2021 Annual Meeting. If and to the extent that (a) SPM requests in writing that the Company nominate the Saddle Point Designees at the Company’s 2021 annual meeting of stockholders (including any adjournments or postponements thereof, the “2021 Annual Meeting”) prior to the deadline under the Amended and Restated Bylaws of the Company (the “Bylaws”) for advance notice of director nominations proposed to be made by Company stockholders at the 2021 Annual

Operations & Safety Committee. Promptly following the election of the Saddle Point Designees to the Board, the Board shall take all necessary actions to establish a committee of the Board (and to maintain such committee through the expiration of the Standstill Period) which shall be named the “Operations & Safety Committee” (the “Operations & Safety Committee”) to coordinate, provide oversight and report recommendations, from time to time, regarding the Company’s operational objectives, including transportation and logistics, ERP and technology-enabled operational improvements, and supervision and general safety matters, including regulatory, environmental and compliance matters relevant to the Company. In furtherance of the foregoing, the Operations & Safety Committee shall consider in good faith to retain one or more individuals recommended by SPM to provide recommendations to such committee with respect to, among other things, the Company’s new enterprise resource planning system’s cost, implementation and operation.

Hagen, with Miller serving as the Chairman of such committee. The Operations & Safety Committee shall (i) meet promptly after the date that the Saddle Point Designees are elected to the Board to organize, plan and commence the evaluation and review to be performed in accordance with this letter agreement, and (ii) be provided with the technical resources and authority reasonably necessary for such committee to discharge its purpose, including, without limitation, to retain and terminate

Expenses. Each party will be responsible for its own fees and expenses incurred in connection with the execution and effectuation of this letter agreement and the transactions contemplated hereby, except that the Company will, subject to an aggregate cap of $500,000, reimburse SPM and Maxima Fund for their reasonable, documented out-of-pocket expenses, including legal fees, incurred in connection with the negotiation and entry into this letter agreement and other matters related to the Company’s 2020 Annual Meeting.  10. Annual Meeting Timing and Voting Agreement. The Company agrees to hold the 2020 Annual Meeting prior to June 1, 2020, subject to any delay necessitated by compliance with applicable law or regulatory, judicial or stock exchange order, published interpretation or similar requirements.

Further, in connection with such meeting or meetings, SPM shall vote or cause to be voted any Company Common Stock beneficially owned by SPM or Maxima Fund or any other Saddle Point Affiliate as of the time of such meeting in favor of the election of directors nominated by the Board (provided such nominees include the Saddle Point Designees). Notwithstanding the foregoing, each of SPM and Maxima Fund shall be entitled to (i) vote its shares on any other proposal brought before the 2020 Annual Meeting (or any adjournments or postponements thereof) or otherwise vote as it determines in its sole discretion, and (ii) disclose, publicly or otherwise, how it intends to vote or act with

Saddle Point Management, L.P. March 26, 2020 Page 7  9986/48254-001 CURRENT/115004776v10 US-DOCS\114747541.7  b.

The foregoing shall not (i) restrict the ability of any party or its representatives to comply with any applicable subpoena or other legal process or respond to a request for information from any governmental authority, other legal requirement or the rules of any securities exchange to which it is subject, (ii) apply to any party’s internal communications, (iii) apply to private communications between any party or their controlled affiliates and such party’s directors, officers, employees, agents or representatives acting on such party’s behalf, on the one hand, and the Company or any of its subsidiaries, directors, officers, employees, agents or representatives acting on their behalf, on the other hand or (iv) prohibit a response by a party to any statement made by the other party or any of its agents, subsidiaries, Affiliates, successors, assigns, officers, key employees or directors which is in violation of this Section 14. 15. Equitable Relief; Specific Performance.
