EXHIBIT A
RESTRICTED STOCK UNIT AGREEMENT

This Restricted Stock Unit Agreement (together with the Grant Notice to which this Agreement is attached, this “Agreement”) is made as of the Date of Grant set forth in the Grant Notice to which this Agreement is attached by and between NET Power Inc., a Delaware corporation (the “Company”), and [●] (the “Participant”). Capitalized terms used but not specifically defined herein shall have the meanings specified in the Plan or the Grant Notice.

1.Award. Effective as of the Date of Grant set forth in the Grant Notice (the “Date of Grant”), the Company hereby grants to the Participant the number of RSUs set forth in the Grant Notice on the terms and conditions set forth in the Grant Notice, this Agreement and the Plan, which is incorporated herein by reference as a part of this Agreement. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. To the extent vested, each RSU represents the right to receive one Share, subject to the terms and conditions set forth in the Grant Notice, this Agreement and the Plan. Unless and until the RSUs have become vested in the manner set forth in the Grant Notice, the Participant will have no right to receive any Shares or other payments in respect of the RSUs. Prior to settlement of this Award, the RSUs and this Award represent an unsecured obligation of the Company, payable only from the general assets of the Company.

2.Vesting of RSUs.

a.Except as otherwise set forth in Sections 2, the RSUs shall vest in accordance with the vesting schedule set forth in the Grant Notice. Upon the Participant’s Termination of Service prior to the vesting of all of the RSUs (but after giving effect to any accelerated vesting pursuant to this Section 2), any unvested RSUs (and all rights arising from such RSUs and from being a holder thereof) will terminate automatically without any further action by the Company and will be forfeited without further notice and at no cost to the Company.

b.Upon the Participant’s Termination of Service by the Company or an Affiliate without Cause or due to the Participant’s resignation, a Pro-Rated Amount of any RSUs that remain unvested shall immediately become vested as of the date of such Termination of Service. For purposes of this Agreement, “Pro-Rated Amount” means (i) the product of the total number of RSUs granted pursuant to this Award and (ii) a fraction, the numerator of which is the total number of calendar days that have elapsed from the Date of Grant through the date of the Termination of Service and the denominator of which is the total number of calendar days between the Grant Date and final vesting date set forth in the Grant Notice.

c.Notwithstanding anything in the Grant Notice, this Agreement or the Plan to the contrary, the RSUs shall immediately become fully vested upon (i) the Participant’s Termination of Service due to the Participant’s death or Disability or (ii) a Change in Control, in each case, so long as the Participant continuously



provides services to the Company or an Affiliate from the Date of Grant through such event.

3.Dividend Equivalent Rights. If the Company declares and pays a regular cash dividend in respect of its outstanding Shares (which, for clarity, does not include any extraordinary cash dividend) and, on the record date for such dividend, the Participant holds RSUs granted pursuant to this Agreement that have not been settled, then:

a.If the Participant has not elected to defer delivery of the Shares in settlement of the RSUs in accordance with Section 4, then the Company shall record in a bookkeeping account for payment to the Participant, an amount in cash equal to the cash dividends the Participant would have received if the Participant was the holder of record, as of such record date, of a number of Shares equal to the number of RSUs held by the Participant that have not been settled as of such record date (the “Dividend Equivalent Rights”). The Dividend Equivalent Rights will be paid to the Participant within 60 days following the date the RSUs to which they are attributable vest. For purposes of clarity, if any of the RSUs are forfeited by the Participant pursuant to the terms of this Agreement, then the Participant shall also forfeit the Dividend Equivalent Rights, if any, accrued with respect to such forfeited RSUs. No interest will accrue on the Dividend Equivalent Rights between the declaration and payment of the applicable dividends and the payment of the Dividend Equivalent Rights; and

b.If the Participant has elected to defer delivery of the Shares in settlement of the RSUs in accordance with Section 4, then, the Company shall credit the Participant with Dividend Equivalent Rights in the form of an additional number of RSUs having a value as of the record date for the dividend equal to the cash dividends the Participant would have received if the Participant was the holder of record, as of such record date, of a number of Shares equal to the number of RSUs held by the Participant that have not been settled as of such record date, rounded down to the nearest whole Share. Once credited to the Participant, any such additional RSUs shall be considered RSUs under this Agreement (and shall also be credited with additional RSUs as Dividend Equivalent Rights if and when the Company declares and pays additional regular cash dividends in respect of its outstanding Shares) and shall vest and be settled in accordance with the terms of this Agreement.

4.Settlement of RSUs. As soon as administratively practicable following the vesting of RSUs pursuant to Section 2, but in no event later than 60 days after such vesting date, the Company shall deliver to the Participant a number of Shares equal to the number of RSUs subject to this Award. All Shares issued hereunder shall be delivered either by delivering one or more certificates for such shares to the Participant or by entering such shares in book-entry form, as determined by the Committee in its sole discretion. The value of Shares shall not bear any interest owing to the passage of time. Neither this Section 4 nor any action taken pursuant to or in accordance with this Agreement shall be construed to create a trust or a funded or secured obligation of any kind. Notwithstanding the preceding provisions of this Section 4, the Participant may elect to defer the delivery of the Shares in settlement of the RSUs pursuant to the Non-Employee Director Deferral



Election Form as separately provided to the Participant. Any such deferral election shall be made in compliance with such rules and procedures as the Committee prescribes from time to time. If the Participant elects to defer delivery of the Shares in settlement of the RSUs, the Company will deliver to the Participant a number of Shares equal to the number of RSUs subject to this Award at such time as provided in the Non-Employee Director Deferral Election Form rather than the settlement time specified in the first sentence of this Section 4.

5.Tax Withholding. To the extent that the receipt, vesting or settlement of this Award results in compensation income or wages to the Participant for federal, state, local and/or foreign tax purposes, the Participant shall make arrangements satisfactory to the Company regarding the payment of any income tax, social insurance contribution or other applicable taxes that are required to be withheld in respect of this Award, which arrangements include the delivery of cash or cash equivalents, Shares (including previously owned Shares (which are not subject to any pledge or other security interest), net settlement, a broker-assisted sale, or other cashless withholding or reduction of the amount of shares otherwise issuable or delivered pursuant to this Award), other property, or any other legal consideration the Committee deems appropriate. If such tax obligations are satisfied through net settlement or the surrender of previously owned Shares, the maximum number of Shares that may be so withheld (or surrendered) shall be the number of Shares that have an aggregate Fair Market Value on the date of withholding or surrender equal to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for federal, state, local and/or foreign tax purposes, including payroll taxes, that may be utilized without creating adverse accounting treatment for the Company with respect to this Award, as determined by the Committee. Any fraction of a Share required to satisfy such tax obligations shall be disregarded and the amount due shall be paid instead in cash to the Participant. The Participant acknowledges that there may be adverse tax consequences upon the receipt, vesting or settlement of this Award or disposition of the underlying shares and that the Participant has been advised, and hereby is advised, to consult a tax advisor. The Participant represents that the Participant is in no manner relying on the Board, the Committee, the Company or an Affiliate or any of their respective managers, directors, officers, employees or authorized representatives (including attorneys, accountants, consultants, bankers, lenders, prospective lenders and financial representatives) for tax advice or an assessment of such tax consequences.

6.Non-Transferability. During the lifetime of the Participant, the RSUs may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution, unless and until the Shares underlying the RSUs have been issued, and all restrictions applicable to such Shares have lapsed. Neither the RSUs nor any interest or right therein shall be liable for the debts, contracts or engagements of the Participant or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means, whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect, except to the extent that such disposition is permitted by the preceding sentence.




7.Compliance with Applicable Law. Notwithstanding any provision of this Agreement to the contrary, the issuance of Shares hereunder will be subject to compliance with all applicable requirements of applicable law with respect to such securities and with the requirements of any stock exchange or market system upon which the Shares may then be listed. No Shares will be issued hereunder if such issuance would constitute a violation of any applicable law or regulation or the requirements of any stock exchange or market system upon which the Shares may then be listed. In addition, Shares will not be issued hereunder unless (a) a registration statement under the Securities Act is in effect at the time of such issuance with respect to the Shares to be issued or (b) in the opinion of legal counsel to the Company, the Shares to be issued are permitted to be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary for the lawful issuance and sale of any Shares hereunder will relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority has not been obtained. As a condition to any issuance of Shares hereunder, the Company may require the Participant to satisfy any requirements that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company.

8.Rights as a Stockholder. The Participant shall have no rights as a stockholder of the Company with respect to any Shares that may become deliverable hereunder unless and until the Participant has become the holder of record of such Shares, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such Shares, except as otherwise specifically provided for in the Plan or this Agreement.

9.Execution of Receipts and Releases. Any issuance or transfer of Shares or other property to the Participant or the Participant’s legal representative, heir, legatee or distributee, in accordance with this Agreement shall be in full satisfaction of all claims of such Person hereunder. As a condition precedent to such payment or issuance, the Company may require the Participant or the Participant’s legal representative, heir, legatee or distributee to execute (and not revoke within any time provided to do so) a release and receipt therefor in such form as it shall determine appropriate; provided, however, that any review period under such release will not modify the date of settlement with respect to any vested RSUs.

10.No Right to Continued Service or Awards. Neither the adoption of the Plan nor the award of the RSUs hereunder pursuant to the Grant Notice and this Agreement, shall confer upon the Participant the right to a continued service relationship with, the Company or any Affiliate, or any other entity, or affect in any way the right of the Company or any such Affiliate, or any other entity to terminate such other service relationship at any time. The grant of the RSUs hereunder is a one-time benefit that was made at the sole discretion of the Company and does not create any contractual or other right to receive any grant of Awards in the future or any benefits in lieu of any Awards in the future. Any future Awards will be granted at the sole discretion of the Company.




11.Notices. All notices and other communications under this Agreement shall be in writing and shall be delivered to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):

15.Severability and Waiver.

Waiver by any party of any breach of this Agreement or failure to exercise any right hereunder shall not be deemed to be a waiver of any other breach or right. The failure of any party to take action by reason of such breach or to exercise any such right shall not deprive such party of the right to take action at any time while or after such breach or condition giving rise to such right occurs.

16.Company Recoupment of Awards. The Participant’s rights with respect to this Award shall in all events be subject to (a) any right that the Company may have under any Company recoupment policy, including the Company’s Clawback Policy, as in effect from time to time, or any other agreement or arrangement with the Participant, and (b) any right or obligation that the Company may have regarding the clawback of “incentive-based compensation” under Section 10D of the Exchange Act and any applicable rules and regulations promulgated thereunder from time to time by the U.S. Securities and Exchange Commission or any other Applicable Law.

19.Headings; References; Interpretation. Headings are for convenience only and are not deemed to be part of this Agreement. The words “hereof,” “herein” and “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All references herein to Sections shall, unless the context requires a different construction, be deemed to be references to the Sections of this Agreement. The word “or” as used herein is not exclusive and is deemed to have the meaning “and/or.” All references to “including” shall be construed as meaning “including without limitation.” Unless the context requires otherwise, all references herein to a law, agreement, instrument or other document shall be deemed to refer to such law, agreement, instrument or other document as amended, supplemented, modified and restated from time to time to the extent permitted by the



provisions thereof. All references to “dollars” or “$” in this Agreement refer to United States dollars.

21.Section 409A. This Agreement and the RSUs are intended to comply with, or be exempt from, the applicable requirements of Section 409A of the Code and shall be limited, construed and interpreted in accordance with such intent. Notwithstanding any contrary provision in the Plan or this Agreement, any payment(s) of “nonqualified deferred compensation” (within the meaning of Section 409A of the Code) that are otherwise required to be made under the Plan or this Agreement to a “specified employee” (as defined under Section 409A of the Code) as a result of such employee’s separation from service (other than a payment that is not subject to Section 409A of the Code) shall be delayed for the first six (6) months following such separation from service (or, if earlier, until the date of death of the specified employee) and shall instead be paid (in a manner set forth in this Agreement) upon expiration of such delay period. Notwithstanding the foregoing, neither the Company nor any of its Affiliates makes any representation that the RSUs provided under this Agreement are exempt from, or compliant with, Section 409A of the Code, and in no event shall the Company or any Affiliate be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Participant on account of non-compliance with Section 409A of the Code.
