TO: Restricted Stock Unit Holder

RE: Restricted Stock Unit Cancellation and Release Agreement

This is an agreement and release (this “Agreement”) that provides for cancellation of your outstanding restricted stock unit award(s) (“RSU Awards”), pursuant to which you could be issued shares of common stock of IKONICS Corporation (the “Company”), in exchange for cash payment equal to $33.82 for each share underlying the unvested portion of your RSU Awards, net of any applicable withholding taxes.

As previously communicated to you, the Company is party to an Agreement and Plan of Merger, dated as of June 24, 2021 by and among the Company, Telluride Holdco, Inc. (“Holdco”), Telluride Merger Sub I, Inc., Telluride Merger Sub II, Inc., and TeraWulf Inc., as amended (the “Merger Agreement”). As a result of the transactions contemplated by the Merger Agreement, each share of the Company’s common stock will be converted into and exchanged for the right to receive (collectively, the “Merger Consideration”): (i) one share of Holdco common stock, (ii) one Contingent Value Right (as more fully described in the Merger Agreement), and (iii) $5.00 in cash. Additionally, the legacy stockholders of TeraWulf Inc. will own approximately 98% of the outstanding common stock of Holdco immediately after closing.

Pursuant to the terms of the Merger Agreement, your RSU Awards are eligible to vest and settle into shares of Company common stock in advance of the closing, which shares would be eligible to convert into the right to receive the Merger Consideration. Vesting of your RSU Awards is a taxable event subject to immediate tax withholding and, pursuant to the Company’s 2019 Equity Incentive Plan (the “Plan”) and the award agreement(s) issued thereunder governing your RSU Awards, persons receiving shares must pay a cash amount sufficient to cover any required withholding taxes before actual receipt of those Shares.

For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, by signing below you agree as follows:

1.    RSU Awards Held. You acknowledge and agree that (i) Schedule A attached to this Agreement (“Schedule A”) reflects all outstanding RSU Awards held by you and the number of shares subject to such RSU Awards.

2.    RSU Award Consideration and Cancellation. You will be entitled to receive in settlement and full satisfaction of your rights under the RSU Awards that are outstanding immediately prior to the effective time of the First Merger (as defined in the Merger Agreement) (the “Effective Time”) a cash payment equal to $33.82 for each share underlying the unvested portion of your RSU Awards, net of any applicable withholding taxes (the “Payment”). In exchange for the Payment, you agree that all of your rights under the RSU Awards will terminate and be cancelled as of immediately prior to the Effective Time and become solely the right to receive the Payment, subject to any applicable withholding tax obligations.

3.    Payment. The Payment will be paid by the Company to you as soon as practicable following the Effective Time (but in any event not later than ten business days thereafter), net of any applicable withholding taxes.

4.    Tax Withholding. Any amount paid pursuant to this Agreement will be net of all applicable federal, state and local withholding taxes, including the withholding taxes described above. All such withholding taxes shall be withheld and remitted to the appropriate taxing authority and such remittance shall be deemed a payment to you of amounts owed under this Agreement. You acknowledge that the Company is not making any representations or warranties with respect to the tax treatment of any of the amounts paid hereunder and, by entering into this agreement, you agree to accept any and all such tax consequences.

5.    Release. In consideration of the Payment, you hereby release and discharge the Company and Holdco, and their affiliates, directors, officers, employees, and agents, and the respective administrators, legal representatives, heirs, successors and assigns of each (collectively, the “Releasees”), of and from any and all actions or causes of actions, suits or claims whatsoever in law and equity against any of the Releasees that you may now have or that may hereafter arise out of or in connection with the RSU Awards, the Plan, and any award agreement under the Plan, including but not limited to the treatment of the RSU Awards as set forth in this Agreement.

6.    Condition Precedent. The payment of the consideration described in Section 2 of this Agreement and the release described in Section 5 herein are conditioned upon the occurrence of the Effective Time.

7.    Further Assurances. You agree to execute and/or cause to be delivered to the Company such instruments and other documents, and shall take such other actions, as the Company may reasonably request for the purpose of carrying out or evidencing the provisions of this Agreement.

8.    Successors and Heirs. This Agreement shall run to the benefit of the Releasees and shall be binding on the successors and heirs of the parties hereto.
