Hudson Executive Capital LP

c/o Cadwalader, Wickersham & Taft LLP

200 Liberty Street

New York, New York 10281

Ladies and Gentlemen:

ViewRay, Inc. (the “Company”) and Hudson Executive Capital LP, on behalf of itself, its affiliates and its affiliated funds (such affiliates and affiliated funds (which, for the avoidance of doubt, shall include HEC Management GP LLC and HEC Master Fund LP), together with Hudson Executive Capital LP, collectively, “Hudson”), have agreed to the terms contained in this Cooperation Agreement (this “Agreement”). This Agreement will take effect as of the date hereof (the “Effective Date”). For purposes of this Agreement, we refer to each of the Company and Hudson as a “Party” and, together, as the “Parties”.

Company Board and Related Matters.

(a) Board Observer.

(i) The Company agrees that Sai Nanduri, Senior Investment Analyst of Hudson, shall serve as an observer (the “Initial Observer”) of the Board of Directors of the Company (the “Board”) beginning on January 20, 2023 until the earliest to occur of (x) the Expiration Date, (y) the designation of a Successor Observer in accordance with Section 1(a)(ii) and (z) the appointment of the Initial Observer as a director of the Company in accordance with Section 1(b). For the purposes of this Agreement, all references to the “Observer” shall be deemed references to the Initial Observer or any Successor Observer in the event that a Successor Observer is appointed in accordance with Section 1(a)(ii), as applicable.

(ii) If, during the Term, the Observer ceases to be employed by or affiliated with Hudson, the Observer shall immediately cease to be the Observer and Hudson shall be entitled to select another individual employed by Hudson and reasonably acceptable to the Company to act as the Observer (a “Successor Observer”) until the earliest to occur of (x) the Expiration Date, (y) the designation of a Successor Observer in accordance with this Section 1(a)(ii) and (z) the appointment of the Successor Observer as a director of the Company in accordance with Section 1(b). The Successor Observer shall have qualifications and experience that are substantially similar to those of the Initial Observer (the “Observer Qualifications”).

(iii) The Company shall take all necessary actions to promptly install any Successor Observer as an observer of the Board; provided, that such Successor Observer shall be subject to the approval (not to be unreasonably withheld) of the Board; provided, further, that the Board may only reject the Successor Observer if such person fails to satisfy the Observer Qualifications. If the Successor Observer initially proposed by Hudson is rejected based on a failure to satisfy the Observer Qualifications, Hudson shall be entitled, until the earliest to occur of (x) the Expiration Date, (y) the appointment of a Successor Observer in accordance with Section 1(a)(ii) and (z) the appointment of the Observer as a director of the Company in accordance with Section 1(b), to continue proposing persons as the Successor Observer and any such proposed person shall be promptly installed as the Successor Observer (subject only to the Board’s right to reject such person’s candidacy as Successor Observer for a failure to satisfy the Observer Qualifications). The onboarding of the Successor Observer will be through a reasonable and customary process no more onerous, burdensome or time consuming than the process for onboarding the Initial Observer, and there will be no procedure, policy or other obstacle implemented with the intent or effect of prejudicing the Successor Observer’s ability to timely act in such capacity.

(iv) Notwithstanding anything in this Agreement to the contrary, the rights with respect to the designation of a Successor Observer pursuant to this Section 1(a) shall be subject to Hudson having aggregate beneficial ownership of at least three percent (3%) of the shares of the common stock of the Company, par value $0.01 per share (“Common Stock”), outstanding at such time; provided, that for purposes of such calculation, the total outstanding shares of Common Stock as of the date of such determination shall be deemed to be the lesser of (1) the aggregate number of shares of Common Stock outstanding as of the date hereof or (2) the aggregate number of shares of Common Stock outstanding as of the date of such determination (in each case, as equitably adjusted for any combinations, splits, recapitalizations or similar actions).

(v) The Company agrees that the Observer may attend all meetings (including telephonic or videoconference meetings), including in executive session, of the Board and its committees, in each case, solely in a non-voting observer capacity. The Observer may participate fully in discussions of all matters brought to the Board and its committees for consideration, but in no event shall the Observer: (i) be deemed to be a member of the Board or any committee thereof; (ii) have the right to propose or offer any motions or resolutions of the Board or any committee thereof; or (iii) have the right to vote with respect to any motions or resolutions proposed or offered to the Board or any committee thereof or otherwise have any power to cause the Company to take, or not to take, any action. The presence or absence of the Observer shall not be required or taken into account for purposes of establishing a quorum. The Company shall provide to the Observer copies of all notices, minutes, consents, and other materials that it provides to the directors of the Company (collectively, “Board Materials”), at the same time and in the same manner as such Board Materials are delivered to the directors of the Company. Notwithstanding anything in this Agreement to the contrary, the Company may exclude the Observer from access to any

Board Materials, meeting or portion thereof if, and only to the extent that, the Board or the relevant committee, as applicable, acting in good faith after consultation with legal counsel, reasonably concludes that: (i) such exclusion is necessary to preserve the attorney-client or work product privilege between the Company or its Affiliates and its legal counsel; (ii) such Board Materials or discussions relate to the Company’s or its Affiliates’ relationship, contractual or otherwise, with Hudson or its Affiliates or any actual or potential transactions between or involving the Company or its Affiliates and Hudson and its Affiliates, or (iii) such exclusion from a meeting in executive session is necessary to limit such session solely to independent directors of the Company, independent auditors and/or legal counsel, and the Board determines that the Observer (assuming the Observer were a director of the Company) would not meet the then applicable standards for independence under the rules and regulations of the Nasdaq Stock Market or applicable law.

(b) Vacancies. The Company agrees that the Board shall fill any vacancy on the Board arising during the Term, subject, in the case of any Successor Observer, to the customary vetting processes, including interviews and other onboarding and compliance procedures, of the Nominating and Corporate Governance Committee of the Board (it being agreed that the Initial Observer has completed the vetting processes and shall be subject only to a bring-down vetting process, including updated background and credentials checks), with the Observer (the “Observer Director”); provided, however, that, notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall be construed to give Hudson any nomination rights with respect to proposals for the candidates for election to the Board at the 2023 Annual Meeting which, for the avoidance of doubt, shall remain at the sole discretion of the Company.

(i) Meetings. At any annual or special meeting of shareholders of the Company during the Standstill Period (including any action of the shareholders by written consent), Hudson shall, or shall cause its Affiliates, Associates (each as defined in Rule 12b-2 promulgated by the SEC under the Exchange Act of 1934, as amended (together with the rules and regulations thereunder, the “Exchange Act”)) or representatives to, appear in person or by proxy at such meeting (or submit written consents) and vote all shares of Common Stock over which Hudson, its Affiliates or Associates has voting power (A) in favor of all directors nominated by the Board for election at any such meeting, (B) in accordance with the Board’s recommendation with respect to any proposal to be submitted to the shareholders of the Company; provided, however, that Hudson shall be permitted to vote in its discretion on any proposal of the Company in respect of any Extraordinary Transaction (as defined below).

(ii) Interim Special Meetings. During the Term, the Company shall not call or hold any interim special meeting of shareholders for the purpose of removing and/or replacing the Observer Director.

(d) Company Policies. The Company Policies will be applicable to any Observer Director while serving as a director of the Company. The Company represents and

warrants that all Company Policies currently in effect are publicly available on the Company’s website or have been provided to Hudson or its counsel. For the avoidance of doubt, the Company Policies shall not apply to the Observer or Hudson or any of their affiliated funds. For purposes of this Agreement, “Company Policies” shall mean the policies, procedures, processes, codes, rules, standards and guidelines applicable to directors of the Company, including the Corporate Governance Guidelines and Code of Business Conduct and Ethics, and any other policies applicable to members of the Board, including, but not limited to, policies related to stock ownership, public disclosures and confidentiality (as may be amended from time to time) then in effect.

(e) Non-Interference. The Company will not take any action to frustrate the purposes of this Agreement, including by (i) amending or making any alterations to its organizational documents or any Company Policies or (ii) utilizing any existing or new committee of the Board, in each case, to such end.

(f) Board Observer Agreement.

(i) Concurrently with the execution and delivery of this Agreement, the Company has entered into a board observer agreement (the “Board Observer Agreement”) with Sai Nanduri. In the event of any Successor Observer, the Company and such Successor Observer shall enter into a board observer agreement Observer on substantially similar terms.

(ii) Concurrently with the execution and delivery of this Agreement, the Company, Hudson and Sai Nanduri, in his capacity as the Observer, have entered into a nondisclosure agreement (the “Nondisclosure Agreement”), which Nondisclosure Agreement, on the terms and subject to the conditions set forth therein, shall govern Sai Nanduri’s obligations as the Observer with respect to Confidential Information (as defined in the Nondisclosure Agreement). In the event of any Successor Observer, the Company and such Successor Observer shall enter into a nondisclosure agreement on terms substantially similar to the Nondisclosure Agreement. For the avoidance of doubt, the Parties agree that the Nondisclosure Agreement shall in no event restrict or limit the ability of Hudson to engage in a proxy contest.

2. Standstill Restrictions. During the Standstill Period, Hudson shall not, and shall cause its controlling and controlled Affiliates and Associates not to, directly or indirectly, in any manner:

(a) purchase or otherwise acquire, or offer, seek, propose or agree to acquire, beneficial ownership of Common Stock such that, giving effect to such purchase or acquisition, Hudson’s beneficial ownership of Common Stock would exceed 14.9% of the Common Stock outstanding;
