AMENDED PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our board of directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Unless the board of directors determines that vacancies (including vacancies created by increases in the number of directors) shall be filled by the stockholders, and except as otherwise provided by law, vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors.

Effective as of May 19, 2023, the board of directors will consist of six seated directors, divided into the three following classes:

Ron Nicol serves as Chairman of the board of directors.

Any director may be removed from office by the stockholders of the Company as provided in Section 141(k) of the DGCL.

At each annual meeting of stockholders of the Company, stockholders will be asked to elect all of the directors of the class of directors whose term expires at the conclusion of that applicable annual meeting of stockholders. All such directors, whether newly elected or re-elected, shall be elected for a three-year term.

Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two nominees named below. In the event that any nominee should be unavailable for election as a result of an unexpected occurrence, those shares will be voted for the election of those substitute nominees as the board of directors may propose. Each person nominated for election has agreed to serve if elected, and management has no reason to believe that any nominee will be unable to serve.

Directors are elected by a plurality of the votes cast at the meeting.

The following table sets forth, for the Class I directors and for our other current directors, information with respect to their position/office held with the Company and their ages as of May 19, 2023:

(1) Includes board service at Legacy Nuburu.

(2) Member of the audit committee.

(3) Member of the compensation committee.

(4) Member of the nominating and corporate governance committee.

Set forth below and in the Proxy Statement is biographical information for the nominees and each person whose term of office as a director will continue after the Annual Meeting. The following and the Proxy Statement includes certain information regarding our directors’ individual experience, qualifications, attributes and skills that led the board of directors to conclude that they should serve as directors.
