Dear Paul:

This letter agreement (this “Agreement”) sets forth our mutual understanding and agreement concerning your employment with TeraWulf Inc., a Delaware corporation (together with any of its subsidiaries and affiliates as may employ you from time to time, and any and all successors thereto, the “Company”).

Term; Effectiveness. The period of your employment under this Agreement (the “Term”) will commence as of May 1, 2021 (the “Effective Date”), and will continue until the first anniversary of the Effective Date (the “Initial Term”). The Initial Term will be automatically extended for successive one-year periods (each such one-year period, a “Renewal Term”), unless either party provides written notice that the Term will not be so extended to the other party at least sixty (60) days prior to the last day of the then current term (e.g., Initial Term or Renewal Term, as applicable).

Position, Authority, Duties and Responsibilities. During the Term, you will be employed in the position of Chief Executive Officer of the Company and will have such authority, duties and responsibilities as are customary for such positions. You will report to the Board of Directors of the Company (the “Board”). If requested by the Board, you will also serve as an officer of subsidiaries or affiliates of the Company. Except as otherwise provided herein, you will not be entitled to any additional compensation for your service for other positions or titles you may hold with any subsidiaries or affiliates of the Company to the extent you are so appointed. Notwithstanding the preceding, you will be permitted to be involved with the businesses set forth on Annex I attached hereto.

You agree to observe and comply with the Company’s rules and policies as adopted from time to time by the Company. You will devote the majority of your business time, skill, attention and best efforts to the performance of your duties hereunder; provided, however, that you will be entitled to (i) serve on civic, charitable, and religious boards and (ii) manage your personal and family investments, in each case, to the extent that such activities do not materially interfere with the performance of your duties and responsibilities hereunder, are not in conflict with the business interests of the Company or its subsidiaries or affiliates and do not otherwise compete with the business of the Company or any of its subsidiaries or affiliates.

Annual Base Salary. During the Term, for all services rendered under this Agreement, you will receive an annual base salary of $950,000, payable in accordance with the Company’s applicable payroll practices.

Annual Bonus. During the Term, you will be eligible to earn an annual fiscal year performance-based bonus (the “Annual Bonus”), with a target of 150% of your annual base salary, based upon both objective and/or subjective factors set annually by the Compensation Committee of the Board (the “Compensation Committee”), as applicable, and communicated to you at the beginning of the relevant year. Each such Annual Bonus will be payable on such date as is determined by the Compensation Committee, but in any event within the period required by Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), such that it qualifies as a “short-term deferral” pursuant to Section 1.409A-1(b)(4) of the Department of Treasury Regulations (or any successor thereto). Notwithstanding the foregoing, no Annual Bonus will be payable with respect to any calendar year unless you remain continuously employed with the Company on the date of payment.

Equity Compensation.  During the Term, you shall be eligible to receive equity-based compensation awards under the Company’s 2021 Omnibus Incentive Plan (or its successor plan) from time to time, as determined by the Board (or a subcommittee thereof) in its sole discretion.

Benefits. During the Term, you will be entitled to participate in the Company’s benefit plans and programs generally made available from time to time for its employees generally, including, but not limited to medical, 401(k), and paid time off, subject to the terms and conditions of such plans and programs. The Company reserves the right to amend, modify or terminate any of its benefit plans or programs at any time and for any reason. The Company will reimburse you for your reasonable expenses incurred in connection with performing your duties hereunder, in accordance with its then prevailing policies and procedures for expense reimbursement.

At-Will Employment; Termination. Your employment with the Company will be “at will,” such that the Company may terminate your employment at any time, with or without reason and with or without notice. You agree to provide the Company with at least sixty (60) days advance written notice of any voluntary resignation of your employment hereunder, and, in such event, the Company in its sole discretion may elect to accelerate the effective date of termination. The Company reserves the right to require that you not be in the offices of the Company or any of its affiliates and/or not undertake all or any of your duties and/or not contact clients, colleagues or advisors of the Company or any of its affiliates (unless otherwise instructed) during all or part of any period of notice of your termination of service (in which case you will be referred to hereunder as being on “garden leave”). During any period of garden leave, your terms and conditions of service and duties of fidelity and confidentiality to the Company will remain in full force and effect and, during any such period, you will remain a service provider to the Company and will not be employed or engaged in any other business.

Upon termination of your employment for any reason, you agree to resign, as of the date of termination or such other date requested by the Company, from all positions and offices that you then hold with the Company and its subsidiaries and affiliates.

Following the termination of your employment with the Company by either party and for any reason, all obligations of the Company to pay or provide you with compensation and benefits will cease, except (i) for the payment of any unpaid base salary or any unreimbursed expenses, in each case accrued or incurred through the effective date of the termination of your employment (the “termination date”), which will be payable as soon as practicable and in all events within 30 days following the termination date, (ii) as explicitly set forth in any other benefit plans or arrangements applicable to terminated employees in which you participate and (iii) as otherwise expressly required by applicable law (collectively, the “Accrued Obligations”). For the avoidance of doubt, except as described in Exhibit A attached hereto, any bonus for the year of termination of employment is forfeited if your employment is terminated for any reason. In addition, if your employment with the Company is terminated in certain circumstances, you (or your estate) will be entitled to receive certain payments and benefits as described in Exhibit A attached hereto, and subject to the conditions set forth therein.

2

Certain Covenants. As a condition of your employment, you agree to be bound by the restrictive covenants set forth in the Restrictive Covenant Agreement (the “Restrictive Covenant Agreement”), attached hereto as Exhibit B, which will be in addition to, and not supersede, any restrictive covenant obligations to which you may otherwise be subject. The Restrictive Covenant Agreement will be executed contemporaneously with this Agreement.

The Company or one of its subsidiaries or affiliates will reimburse you for all of your reasonable out-of-pocket expenses incurred in connection with such cooperation.

Certain Representations. You represent and warrant that as of the date hereof: (i) you have the full right, authority and capacity to enter into this Agreement and perform your obligations hereunder; (ii) you are not bound by any agreement that conflicts with or prevents or restricts the full performance of your duties and obligations to the Company hereunder; and (iii) the execution and delivery of this Agreement will not result in any breach or violation of, or a default under, any existing obligation, commitment or agreement to which you are subject. You acknowledge and agree that the Company shall not have any obligation to reimburse or indemnify you for any losses arising from any breach of the foregoing representations.

The immediately preceding sentence will be deemed inoperative without any action on the part of any person and be void ab initio if the transactions contemplated by the Merger Agreement are abandoned or the Merger Agreement is terminated. For the avoidance of doubt, following such assignment all references to “the Company” or “TeraWulf Inc.” will be deemed to be references to “Telluride Holdco, Inc.” (to be renamed TeraWulf Inc. following the transactions contemplated by the Merger Agreement).

IRC Section 409A. The parties hereto acknowledge and agree that, to the extent applicable, this Agreement will be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A of the Code and the Department of Treasury Regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date (“Section 409A”). Notwithstanding any provision of this Agreement to the contrary, in no event whatsoever will the Company or any of its subsidiaries or affiliates be liable for any additional tax, interest or penalties that may be imposed on you as a result of Section 409A or any damages for failing to comply with Section 409A. Any payments to be made under this Agreement upon a termination of employment that are “nonqualified deferred compensation” shall only be made upon a “separation from service” within the meaning of Section 409A. For purposes of Section 409A, your right to receive installment payments pursuant this Agreement will be treated as a right to receive a series of separate and distinct payments. To the extent that any reimbursement of expenses or in-kind benefits constitutes “nonqualified deferred compensation” under Section 409A, such reimbursement or benefit will be provided no later than December 31 of the year following the year in which the expense was incurred. The amount of expenses reimbursed in one year will not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year will not affect the amount of in-kind benefits provided in any other year. Notwithstanding any other provision of this Agreement, if any payment or benefit provided to you in connection with termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and you are determined to be a “specified employee” as defined in Section 409A(a)(2)(b)(i) of the Code, then such payment or benefit shall not be paid until the first payroll date to occur following the six-month anniversary of your termination date (the “Specified Employee Payment Date”) or, if earlier, on the date of your death. The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date shall be paid to you in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments shall be paid without delay in accordance with their original schedule.

Counterparts. This Agreement may be executed in multiple counterparts, which together shall constitute one and the same agreement. Facsimile, pdf and other true and accurate copies of this Agreement shall have the same force and effect as originals hereof.

Subject to your continued compliance with the covenants contained in the Restrictive Covenant Agreement attached as Exhibit B to the Agreement, if your employment is terminated (i) by the Company without Cause, (ii) due to the Company’s non-renewal of the Term or (iii) your resignation from employment for Good Reason then, in addition to the Accrued Obligations, the Company will:

(a)            pay you a lump-sum cash payment on the sixtieth (60th) calendar day following the termination date in an aggregate amount equal to the annual base salary that would have been paid to you during the eighteen (18)-month period following the termination date (the “Severance Period”), less applicable taxes and withholdings (the “Severance Payment”); provided that, in the event the Company determines that you have materially violated any covenant contained in the Restrictive Covenant Agreement, you will be required to disgorge to the Company a prorated portion of the Severance Payment, determined on a daily basis from the date of such breach through the last day of the Severance Period;

(b)            continue to provide coverage during the Severance Period (or until you become eligible for comparable coverage under the medical health plans of a successor employer, if earlier) for you and any eligible dependents under all Company health and welfare plans in which you and any such dependents participated immediately prior to the termination date, subject to any active-employee cost-sharing or similar provisions in effect for you thereunder as of immediately prior to the termination date; provided that such coverage will not be provided in the event the Company would be subject to any excise tax under Section 4980D of the Code or other penalty or liability pursuant to the provisions of the Patient Protection and Affordable Care Act of 2010 (as amended from time to time), and in lieu of providing the coverage described above, the Company will instead pay to you a fully taxable monthly cash payment in an amount such that, after payment by you of all taxes on such payment, you retain an amount equal to the applicable premiums for such month, with such monthly payment being made on the last day of each month for the remainder of the Severance Period. For the avoidance of doubt, your health benefit coverage from the Company during the Severance Period shall run concurrent with the health continuation coverage period mandated by Section 4980B of the Code;

(c)            pay you a prorated portion of the Annual Bonus payable with respect to the fiscal year in which such termination occurs determined on a daily basis, based on target level of achievement of the applicable performance goals for such year, payable on the sixtieth (60th) calendar day following the termination date;

(e)            treat all outstanding equity awards held by you in accordance with the terms of the applicable equity plan and award agreements; provided that, with respect to awards that vest (i) solely based on continued service with the Company, you will vest in any tranche scheduled to vest in accordance with the applicable award agreement during the Severance Period and (ii) based on the achievement of performance criteria, based on the actual achievement of such performance criteria that occurs during the Severance Period.

2.            Termination due to Disability or Death. Subject to your continued compliance with the covenants contained in Exhibit B, if your employment terminates due to your Disability or death, then, in addition to the Accrued Obligations, the Company will:

(a)            pay you (or your estate) a pro-rata Annual Bonus for the year of termination, determined on a daily basis, based on actual performance for the full year, payable in the same manner and the same time as provided in the “Annual Bonus” section of this Agreement; and

(b)            pay you (or your estate) any previously earned Annual Bonus payable to you for any fiscal year of the Company completed on or before the termination date that has not been paid to you as of the termination date, payable on the sixtieth (60th) calendar day following the termination date.

3.            Release. Notwithstanding anything herein to the contrary, the amounts set forth in this Exhibit A will be contingent upon and subject to your (or your estate’s, if applicable) execution and non-revocation of a general waiver and release of claims agreement in the Company’s customary form (the “Release”) (and the expiration of any applicable revocation period), on or prior to the sixtieth (60th) day following the date of termination.

4.            Definitions. For purposes of this Agreement:

(a)            “Cause” will mean (i) a conviction (after all appeals have been exhausted), guilty plea, or plea of nolo contendere of you of, or to, a felony charge, (ii) the conviction (after all appeals have been exhausted), guilty plea, or plea of nolo contendere of you of, or to, a crime involving fraud or embezzlement that causes material harm to the Company or its stockholders, or (iii) your willful and continued abuse or neglect of your position of Chief Executive Officer of the Company that exists for thirty (30) days after a majority of the Board delivers to you written demand that such abuse or neglect by you of your position as Chief Executive Officer of the Company cease and desist, where such written demand specifically identifies the manner in which such majority of the Board believes that you has so abused or neglected your position of Chief Executive Officer of the Company. For purposes hereof, no act or failure to act on the part of you shall be considered “willful abuse or neglect” unless done or omitted to be done by you in bad faith or without a reasonable believe that such act or omission was consistent with your responsibilities and in the best interest of the Company.

(b)            “Disability” will mean your disability caused by any physical or mental injury, illness or incapacity as a result of which you have been unable to effectively perform the essential functions of your duties for a continuous period of more than 120 days or for any 180 days (whether or not continuous) within a 365-day period, as determined by the Board in good faith. If any question will arise as to whether a Disability exists, you may, and at the request of the Company will, submit to a medical examination by a physician selected by the Company to determine whether a Disability exists and such determination will for the purposes of this Agreement be conclusive of the issue. If such question will arise and you will fail to submit to such medical examination, the Company’s determination of the issue will be binding on you.
