PLUS THERAPEUTICS, INC.

2020 STOCK INCENTIVE PLAN

Stock Unit Agreement

This Stock Unit Agreement and the associated grant award information (the “Customizing Information”), which Customizing Information is provided in written form or is available in electronic form from the recordkeeper for the Plus Therapeutics, Inc. 2020 Stock Incentive Plan, as amended and in effect from time to time (the “Plan”), is made as of the date shown as the “Grant Date” in the Customizing Information (the “Grant Date”) by and between Plus Therapeutics, Inc., a Delaware corporation (the “Company”), and the individual identified in the Customizing Information (the “Recipient”). This instrument and the Customizing Information are collectively referred to as the “Stock Unit Agreement.”

WITNESSETH THAT:

WHEREAS, the Company has instituted the Plan; and

WHEREAS, the Committee has authorized the grant of Stock Units with respect to the Company’s Stock upon the terms and conditions set forth below and pursuant to the Plan, a copy of which is incorporated herein; and

WHEREAS, the Recipient acknowledges that he or she has carefully read this Stock Unit Agreement and agrees, as provided in Section 16(a) below, that the terms and conditions of the Stock Unit Agreement reflect the entire understanding between himself or herself and the Company regarding this Award of Stock Units (and the Recipient has not relied upon any statement or promise other than the terms and conditions of the Stock Unit Agreement with respect to this Award of Stock Units);

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements herein contained and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the Company and the Recipient agree as follows.

1. Grant. Subject to the terms of the Plan and this Stock Unit Agreement, the Company hereby grants to the Recipient that number of Stock Units (“SUs”) equal to the corresponding number of shares of the Company’s Stock (the “Underlying Shares”) shown in the Customizing Information under “Stock Units Granted.”

2. Vesting.

(a) In General. As long as the Recipient remains in an employment or contractual or other service relationship, as applicable (the “Relationship”), with the Company as of a “Vesting Date,” as specified in the Customizing Information, and the Recipient as of such date is not in violation of any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company (each to the extent not otherwise prohibited under applicable state law), all or a portion, as applicable (the “Incremental Amount,” as specified in the Customizing Information), of the SUs shall vest on such date. For the avoidance of doubt, except as otherwise provided pursuant to the terms of the Plan and Section 2(b), if the Recipient’s Relationship with the Company is terminated by the Company or by the Recipient for any reason, whether voluntarily or involuntarily, no SUs granted pursuant to this Stock Unit Agreement shall vest under any circumstances on and after the date of such termination.

(b) Committee Discretion. In the event the Relationship is terminated for any reason (whether voluntary or involuntary), (i) the Recipient’s right to vest in the SUs will, except as otherwise explicitly provided in this Section 2(b) or as provided by the Committee, terminate as of the date of the termination of the Relationship (and will not be extended by any notice period mandated under local law) and (ii) the Committee shall have the exclusive discretion to determine when the Relationship has terminated for purposes of this Stock Unit Agreement (including when the Recipient is no longer considered to be providing active service while on a leave of absence). Notwithstanding the preceding sentence, in the event of the Recipient’s death or Disability, any unvested portion of this SU shall become fully vested.

(c) Special Definitions. For purposes of this Section 2, the term “Company” refers to the Company and any Parent, Subsidiary or Affiliate.

3. Dividends. If so provided in the Customizing Information, a Recipient shall be credited with dividend equivalents equal to the dividends the Recipient would have received if the Recipient had been the actual record owner of the Underlying Shares on each dividend record date on or after the Grant Date and through the date the Recipient receives a settlement pursuant to Section 4 below (the “Dividend Equivalent”). If a dividend on the Stock is payable wholly or partially in Stock, the Dividend Equivalent representing that portion shall be in the form of additional SUs, credited on a one-for-one basis. If a dividend on the Stock is payable wholly or partially in cash, the Dividend Equivalent representing that portion shall also be in the form of cash and a Recipient shall be treated as being credited with any cash dividends, without earnings, until settlement pursuant to Section 4 below. If a dividend on Stock is payable wholly or partially in other than cash or Stock, the Committee may, in its discretion, provide for such Dividend Equivalents with respect to that portion as it deems appropriate under the circumstances. Dividend Equivalents shall be subject to the same terms and conditions as the SUs originally awarded pursuant to this Stock Unit Agreement, and they shall vest (or, if applicable, be forfeited) as if they had been granted at the same time as the original SUs. Dividend Equivalents representing the cash portion of a dividend on Stock shall be settled in cash.

4. Delivery of Underlying Shares or Cash Settlement. With respect to any SUs that become vested SUs as of a Vesting Date pursuant to Section 2, the Company shall issue and deliver to the Recipient as soon as practicable following the applicable Vesting Date (a) the number of Underlying Shares equal to the number of SUs vesting on that date or an amount of cash equal to the Fair Market Value, as defined in the Plan, of such Underlying Shares as of that date (or such later delivery date, if applicable) and (b) the amount (and in the form) due with respect to the Dividend Equivalents applicable to such Underlying Shares. Whether Underlying Shares, or the cash value thereof, shall be issued or paid at settlement shall be determined by the Committee based on the “Form of Settlement” specified in the Customizing Information.

To the extent the vesting of any RSUs occurs during a “blackout” period wherein certain employees, including the Recipient, are precluded from selling Stock, the Committee retains the right, in its sole discretion, to defer the delivery of the Underlying Shares; provided, however, that the Committee shall not exercise its right to defer the Recipient’s receipt of the Underlying Shares if the Stock is specifically covered by a Rule 10b5-1 trading plan of the Recipient that causes the Stock to be exempt from any applicable blackout period then in effect. In the event the receipt of any shares of Stock is deferred hereunder due to the existence of a blackout period, the shares shall be issued to the Recipient on the first day following the termination of the blackout period; provided, however, that in no event shall the issuance of the shares be deferred later than the fifteenth day of the third month following the close of the year in which the Underlying Shares otherwise would have been issued.

Any shares issued pursuant to this Stock Unit Agreement shall be issued, without issue or transfer tax, by (i) delivering a stock certificate or certificates for such shares out of theretofore authorized but unissued shares or treasury shares of its Stock as the Company may elect or (ii) issuance of shares of its Stock in book entry form; provided, however, that the time of such delivery may be postponed by the Company for such period as may be required for it with reasonable diligence to comply with any applicable requirements of law. Notwithstanding the preceding provisions of this Section 4, delivery of Underlying Shares shall be made, or the amount of cash equivalent thereto shall be paid, only if the required purchase price designated as the “Purchase Price” shown in the Customizing Information per underlying SU is paid to the Company by means of payment acceptable to the Company in accordance with the terms of the Plan. If the Recipient fails to pay for or accept delivery of all of the shares, the right to shares of Stock provided pursuant to this Stock Unit Agreement may be terminated by the Company.

5. Withholding Taxes. The Recipient hereby agrees, as a condition of this award, to provide to the Company (or a subsidiary employing the Recipient, as applicable) an amount sufficient to satisfy the Company’s and/or subsidiary’s obligation to withhold any and all federal, state, local or provincial income tax, social security, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items or statutory withholdings related to the Recipient’s participation in the Plan (the “Withholding Amount”), if any, by (a) authorizing the Company and/or any subsidiary employing the Recipient, as applicable, to withhold the Withholding Amount from the Recipient’s cash compensation or (b) remitting the Withholding Amount to the Company (or a subsidiary employing the Recipient, as applicable) in cash; provided, however, that to the extent that the Withholding Amount is not provided by one or a combination of such methods, the Company may at its election withhold from the Underlying Shares and Dividend Equivalents that would otherwise be delivered that number of shares (and/or cash) having a Fair Market Value on the date of vesting sufficient to eliminate any deficiency in the Withholding Amount. Regardless of any action that the Company and/or subsidiary takes with respect to any or all federal, state, local or provincial income tax, social security, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items or statutory withholdings related to the Recipient’s participation in the Plan, the Recipient acknowledges that he or she, and not the Company and/or any subsidiary, has the ultimate liability for any such items. Further, if the Recipient becomes subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable or tax withholding event, the Recipient acknowledges that the Company and/or subsidiary may be required to withhold or account for such tax-related items in more than one jurisdiction.

6. Non-assignability of SUs and Dividend Equivalents. The SUs and Dividend Equivalents shall not be assignable or transferable by the Recipient except by will or by the laws of descent and distribution or as permitted by the Committee in its discretion pursuant to the terms of the Plan. During the life of the Recipient, delivery of shares of Stock or payment of cash as settlement of the SUs and Dividend Equivalents shall be made only to the Recipient, to a conservator or guardian duly appointed for the Recipient by reason of the Recipient’s incapacity or to the person appointed by the Recipient in a durable power of attorney acceptable to the Company’s counsel.

7. Compliance with Securities Act; Lock-Up Agreement. The Company shall not be obligated to sell or issue any Underlying Shares or other securities in settlement of the SUs and Dividend Equivalents hereunder unless the shares of Stock or other securities are at that time effectively registered or exempt from registration under the Securities Act and applicable state or provincial securities laws. In the event shares or other securities shall be issued that shall not be so registered, the Recipient hereby represents, warrants and agrees that the Recipient will receive such shares or other securities for investment and not with a view to their resale or distribution, and will execute an appropriate investment letter satisfactory to the Company and its counsel. The Recipient further hereby agrees that as a condition to the settlement of the SUs and Dividend Equivalents, the Recipient will execute an agreement in a form acceptable to the Company to the effect that the shares shall be subject to any underwriter’s lock-up agreement in connection with a public offering of any securities of the Company that may from time to time apply to shares held by officers and employees of the Company, and such agreement or a successor agreement must be in full force and effect.

8. Legends. The Recipient hereby acknowledges that the stock certificate or certificates (or entries in the case of book entry form) evidencing shares of Stock or other securities issued pursuant to any settlement of an SU or Dividend Equivalent hereunder may bear a legend (or provide a restriction) setting forth the restrictions on their transferability described in Section 7 hereof, if such restrictions are then in effect.

9. Rights as Stockholder. The Recipient shall have no rights as a stockholder with respect to any SUs, Dividend Equivalents or Underlying Shares until the date of issuance of a stock certificate (or appropriate entry is made in the case of book entry form) for Underlying Shares and any Dividend Equivalents. Except as provided by Section 3, no adjustment shall be made for any rights for which the record date is prior to the date such stock certificate is issued (or appropriate entry is made in the case of book entry form), except to the extent the Committee so provides, pursuant to the terms of the Plan and upon such terms and conditions it may establish.

10. Effect Upon Employment and Performance of Services. Nothing in this Stock Unit Agreement or the Plan shall be construed to impose any obligation upon the Company or any subsidiary to employ or utilize the services of the Recipient or to retain the Recipient in its employ or to engage or retain the services of the Recipient.

11. Time for Acceptance. Unless the Recipient shall evidence acceptance of this Stock Unit Agreement by electronic or other means prescribed by the Committee within sixty (60) days after its delivery, the SUs and Dividend Equivalents shall be null and void (unless waived by the Committee).

12. Right of Repayment. In the event that the Recipient breaches any confidentiality, inventions, non-solicitation and/or non-competition agreement with the Company, the Recipient shall pay to the Company an amount equal to the excess of the Fair Market Value of the Underlying Shares as of the date of settlement (whether settled in cash or Stock) over the Purchase Price, if any, paid (or deemed paid) together with the value of any Dividend Equivalents; provided, however, that the Committee in its discretion may release the Recipient from the requirement to make such payment, if the Committee determines that the Recipient’s breach of such agreement is not inimical to the best interests of the Company. In accordance with applicable law, the Company may deduct the amount of payment due under the preceding sentence from any compensation or other amount payable by the Company to the Recipient. For purposes of this Section 12, the term “Company” refers to the Company and any Parent, Subsidiary or Affiliate.

13. Section 409A of the Internal Revenue Code. The SUs and Dividend Equivalents granted hereunder are intended to avoid the potential adverse tax consequences to the Recipient of Section 409A of the Code and the Committee may make such modifications to this Stock Unit Agreement as it deems necessary or advisable to avoid such adverse tax consequences. If and to the extent that the SUs and Dividend Equivalents are subject to Section 409A, any payment upon termination of the Relationship shall be made only upon a “separation from service” under Section 409A and following any delay required by Treas. Reg. § 1.409A-3(i)(2), and the Recipient may not directly or indirectly designate the calendar year of a payment.

14. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Recipient consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

15. Company Policies. The SUs shall be subject to any applicable clawback or recoupment policies, share trading policies, and other policies that may be implemented by the Board from time to time, in accordance with applicable law.

16. General Provisions.

(a) Amendment; Waivers. This Stock Unit Agreement, including the Plan, contains the full and complete understanding and agreement of the parties hereto as to the subject matter hereof, and except as otherwise permitted by the express terms of the Plan and this Stock Unit Agreement and applicable law, it may not be modified or amended nor may any provision hereof be waived without a further written agreement duly signed by each of the parties; provided, however, that a modification or amendment that does not materially diminish the rights of the Recipient hereunder, as they may exist immediately before the effective date of the modification or amendment, shall be effective upon written notice of its provisions to the Recipient, to the extent permitted by applicable law. The waiver by either of the parties hereto of any provision hereof in any instance shall not operate as a waiver of any other provision hereof or in any other instance.
