Consultation Services. The Company hereby employs the Consultant, in its capacity as an independent contractor, to provide general business advisory services to Astrotech’s Senior Management, including but not limited to Thomas B.

Mr. Cantwell and the Consultant have the power and authority to enter into this Agreement and this Agreement does not conflict with or breach any other agreement to which either of them is a party. The scope of such services will be defined Mr. Pickens.

Term of Agreement. This Agreement commenced on December 1, 2014 and shall continue until terminated at the will of either party with 30 days prior notice.

Time Devoted by Consultant. It is anticipated the Consultant will devote approximately 20 hours a week fulfilling its basic general business advisory services obligations under the Agreement. If at any time during the Term of Agreement, Cantwell determines the anticipated time requirement was excessive, he will discuss it with Mr. Pickens and upon mutual agreement as to a fair reduction, the monthly rate described in item 4. below will be adjusted accordingly.

Payment to Consultant. The Consultant will be paid at a monthly rate of $15,000 for services performed under this Agreement, plus reimbursed for any pre-approved travel expenses or other out-of-pocket costs directly related to the engagement.

In addition to the monthly rate, solely at the discretion of Mr. Pickens and Astrotech, if a successful transaction is concluded in which the Consultant provided services hereunder and in the opinion of the Company, Consultant materially contributed to such success, and/or was required to devote substantially more than the anticipated 20 hours a week in order to meet objectives, a performance bonus could be paid. Any such performance bonus could be paid in cash or in such other form as determined solely at the discretion of Mr. Pickens and Astrotech. In its capacity as an Independent Contractor, the Consultant will be responsible for any and all taxes payable in connection with its performance of services under the Agreement.

Place Where Services Will Be Rendered. It is anticipated the Consultant will perform most of the services at its offices at 155 8^th Street North, St. Petersburg, Florida, but will be available for meetings or concentrated work sessions in Austin or such other locations as Mr. Pickens designates.

Cantwell has executed a Confidentiality Agreement with Astrotech dated November 17, 2014 and, as such, the Consultant recognizes any information received in connection with its performance of services under this Agreement will be treated in full confidence.
