WHEREAS, ETFS Capital Limited, a Jersey company, and Graham Tuckwell (collectively, “ETFS”) and Bruce E. Aust and Tonia Pankopf (the “Nominees”) wish to form a group for the purpose of working together to enhance stockholder value at the Company, including seeking representation on the Board of Directors of the Company (the “Board”) at the 2023 annual meeting of stockholders of the Company (including any other meeting of stockholders held in lieu thereof, and any adjournments, postponements, reschedulings or continuations thereof, the “Annual Meeting”), and for the purpose of taking all other action necessary to achieve the foregoing.

NOW, IT IS AGREED, this 12th day of April 2023 by the parties hereto:

1.                   In accordance with Rule 13d-1(k)(1)(iii) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), each of the undersigned (collectively, the “Group”) agrees to the joint filing on behalf of each of them of statements on Schedule 13D, and any amendments thereto, with respect to the securities of the Company, if applicable. Each member of the Group shall be responsible for the accuracy and completeness of his, her or its own disclosure therein, and is not responsible for the accuracy and completeness of the information concerning the other members, unless such member knows or has reason to know that such information is inaccurate.

2.                   For so long as this agreement is in effect, each of the undersigned shall provide written notice to Olshan Frome Wolosky LLP (“Olshan”), such notice to be given no later than four (4) hours after each such transaction, of (i) any of their purchases or sales of securities of the Company or (ii) any securities of the Company over which they acquire or dispose of beneficial ownership; provided, however, that each party agrees not to purchase or sell securities of the Company or otherwise increase or decrease its economic exposure to or beneficial ownership over the securities of the Company if it reasonably believes that, as a result of such action, the Group or any member thereof would be likely to be required to make any regulatory filing (including, but not limited to, a Schedule 13D amendment, Form 3 or Form 4 with the Securities and Exchange Commission (the “SEC”)) without using its reasonable efforts to give the other members of the Group who will be a party to such filing at least twelve (12) hours prior written notice. For purposes of this agreement, the term “beneficial ownership” shall have the meaning of such term set forth in Rule 13d-3 under the Exchange Act.

3.                   Notwithstanding the foregoing, so long as this agreement is in effect, each of the Nominees agree to provide ETFS advance written notice prior to effecting any purchase, sale, acquisition or disposal of any securities of the Company which she has, or would have, direct or indirect beneficial ownership, so that ETFS has an opportunity to review the potential implications of any such transaction in the securities of the Company and pre-clear any such potential transaction in the securities of the Company by the Nominees. Each of the Nominees agree that she shall not undertake or effect any purchase, sale, acquisition or disposal of any securities of the Company without the prior written consent of ETFS.

4.                   Each of the undersigned agrees to form the Group for the purpose working together to enhance stockholder value at the Company, including (i) soliciting proxies or written consents for the election of the persons nominated by the Group to the Board at the Annual Meeting, (ii) taking such other actions as the parties deem advisable, and (iii) taking all other action necessary or advisable to achieve the foregoing.

5.                   Each of the undersigned agrees that all out-of-pocket costs and expenses (including fees of outside legal counsel, but excluding any obligations under any written indemnification agreements between ETFS, on the one hand, and the Nominees, on the other hand, which will be governed by the terms thereof) incurred in connection with the Group’s activities set forth in Section 4 beginning with the activities of ETFS directly relating to its initial formation of the Group, including the preparation of this agreement and any future SEC filings, and so long as this agreement is in effect (the “Expenses”), must be pre-approved by a representative of ETFS, and ETFS agrees to pay directly all such pre-approved expenses. ETFS hereby approves all reasonable Expenses incurred as of the date hereof by such parties and hereby agrees to reimburse the Nominees for their reasonable legal expenses incurred in connection with the review and execution of this agreement and any other documents in connection with such Nominees’ potential nomination by the Group for election as a director of the Company at the Annual Meeting; provided, however, that any such reimbursement shall not exceed $7,500 in the aggregate for each Nominee (plus any applicable VAT/GST or sales taxes).

6.                   Each of the undersigned agrees that any SEC filing, press release, public stockholder communication or Company communication proposed to be made or issued by the Group or any member of the Group in connection with the Group’s activities set forth in Section 4 shall be as directed by ETFS.

8.                   This agreement may be executed in counterparts, each of which shall be deemed an original and all of which, taken together, shall constitute but one and the same instrument, which may be sufficiently evidenced by one counterpart.
