Description of Securities of the Company

DESCRIPTION OF SECURITIES

General

The following summary of certain material terms of the securities of ClearSign Technologies Corporation (the “Company,” “we,” “us” or “our”) is not intended to be a complete summary of the rights and preferences of such securities. You should refer to our bylaws and our certificate of incorporation, which are included as exhibits to the Company’s Current Report on Form 8-K, filed with the Securities and Exchange Commission on June 15, 2023. The summary below is also qualified by reference to the provisions of the Delaware General Corporation Law (the “DGCL”), as applicable.

Authorized and Outstanding Stock

Our certificate of incorporation authorized capital stock consists of 64,500,000 shares, $0.0001 par value per share, consisting of: (i) 62,500,000 shares of common stock; and (ii) 2,000,000 shares of preferred stock.

Common Stock

Dividend Rights

The DGCL permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by the board of directors. The capital of the corporation is typically calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equals the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, capital is less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets. Delaware common law also imposes a solvency requirement in connection with the payment of dividends.

Subject to applicable law and the rights and preferences of any holders of any outstanding series of preferred stock, the holders of common stock will be entitled to the payment of dividends on the common stock when, as and if declared by the Company’s board of directors (“board of directors”) in accordance with applicable law.

Voting Rights

Holders of common stock will be entitled to one vote for each share held as of the record date for determining stockholders entitled to vote on such matters, except as otherwise required by law.

Right to Receive Liquidation Distributions

Subject to the rights and preferences of any holders of any shares of any outstanding series of preferred stock, in the event of any liquidation, dissolution or winding up of the Company, the funds and assets of the Company that may be legally distributed to the stockholders will be distributed among the holders of the then outstanding common stock pro rata in accordance with the number of shares of common stock held by each such holder.

Other Matters

All outstanding shares of the common stock will be fully paid and nonassessable. The common stock will not be entitled to preemptive rights and will not be subject to redemption or sinking fund provisions.

Preferred Stock

Our certificate of incorporation provides that shares of preferred stock may be issued from time to time in one or more series. The board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof,

applicable to the shares of each series. The board of directors will be able to, without stockholder approval, issue preferred stock with voting and other rights that could have anti-takeover effects. The ability of the board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future.

Anti-Takeover Provisions

Certain provisions of Delaware law, the certificate of incorporation, and the bylaws, which are summarized below, may have the effect of delaying, deferring, or discouraging another person from acquiring control of the Company. They are also designed, in part, to encourage persons seeking to acquire control of the Company to negotiate first with the board of directors.

Removal of Directors

Subject to the special rights of the holders of one or more outstanding series of preferred stock to elect directors, the certificate of incorporation provides that directors may be removed from office at any time, with or without cause, only by the affirmative vote of the holders of at least a majority of the voting power of all of the then outstanding shares of voting stock of the Company entitled to vote at an election of directors.

Board of Directors Vacancies

Subject to the special rights of the holders of one or more outstanding series of preferred stock to elect directors, and except as otherwise provided by law, our certificate of incorporation authorizes only a majority of the remaining members of the board of directors (other than any directors elected by the separate vote of one or more outstanding series of preferred stock), even though less than a quorum, to fill vacant directorships, including newly created seats. In addition, the number of directors constituting the board of directors will be permitted to be set only by a resolution of the board of directors. These provisions would prevent a stockholder from increasing the size of the board of directors and then gaining control of the board of directors by filling the resulting vacancies with its own nominees. This will make it more difficult to change the composition of the board of directors and will promote continuity of management.

Stockholder Action; Special Meeting of Stockholders

Our bylaws provide that the our stockholders may take any action required or permitted to be taken at an annual or special meeting of stockholders by written consent in lieu of a meeting. The certificate of incorporation and bylaws further provide that special meetings of the Company’s stockholders may be called only by the chairman of the board of directors, the Chief Executive Officer of the Company or the board of directors pursuant to a resolution adopted by a majority of board of directors, and may not be called by any other person, including the Company’s stockholders.

Section 203 of the DGCL

We have opted out of Section 203 of the DGCL under our certificate of incorporation. As a result, pursuant to our certificate of incorporation, we are prohibited from engaging in any business combination with any stockholder for a period of three years following the time that such stockholder (the “interested stockholder”) came to own at least 15% of our outstanding voting stock (the “acquisition”), except if:

The restrictions described above will apply subject to certain exceptions, including if a stockholder becomes an interested stockholder inadvertently and, as soon as practicable, divests itself of ownership of such shares so that the stockholder ceases to be an interest stockholder, and, within the three (3) year period, that stockholder has not become an interested stockholder but for such inadvertent acquisition of ownership. Generally, a “business combination” or “acquisition” includes any merger, consolidation, asset or stock sale or certain other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our outstanding voting stock.

Our certificate of incorporation provisions that elect to opt out of Section 203 of the DGCL may make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with us for a three-year period. This may encourage companies interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves the acquisition which results in the stockholder becoming an interested stockholder. This may also have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

The bylaws provide that the Company’s stockholders seeking to bring business before the Company’s annual meeting of stockholders, or to nominate candidates for election as directors at the Company’s annual or a special meeting of stockholders must provide timely notice of their intent in writing. To be timely, a stockholder’s notice must be received by the Secretary at the Company’s principal executive offices (i) in the case of an annual meeting, not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day before the anniversary date of the immediately preceding annual meeting of stockholders (subject to certain exceptions), and (ii) in the case of a special meeting of stockholders called for the purpose of electing directors, not later than the close of business on the 10^th day following the day on which public announcement of the date of the special meeting is first made by the Company. The bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude the Company stockholders from bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our certificate of incorporation does not provide for cumulative voting.

Amendment of Certificate of Incorporation Provisions

Amendments to the provisions of the certificate of incorporation related to restrictions on any business combination with any interested stockholder and indemnification of directors and officers of the Company require the affirmative vote of the holders of at least sixty six and two-thirds percent (66 and 2/3%) of the total voting power of all the then outstanding shares of stock of the Company entitled to vote thereon, voting together as a single class.

Authorized but Unissued Capital Stock

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum

The certificate of incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have

jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) and any appellate court thereof shall, to the fullest extent permitted by law, be the sole and exclusive forum for: (i) any derivative action, suit or proceeding (“Proceeding”) brought on behalf of the Company; (ii) any Proceeding asserting a claim of breach of a fiduciary duty owed by any of the Company’s directors, officers, or stockholders to the Company or its stockholders; (iii) any Proceeding arising pursuant to any provision of the DGCL, certificate of incorporation or the bylaws, as amended; (iv) any Proceeding as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; or (v) any Proceeding asserting a claim against the Company or any current or former director, officer or stockholder governed by the internal affairs doctrine. This provision would not apply to suits brought to enforce any liability or duty created by apply to suits brought to enforce any liability or duty created by the Securities Act, the Exchange Act or any other claim for which the federal courts of the United States have exclusive jurisdiction. The certificate of incorporation further provides that, unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. These provisions may have the effect of discouraging lawsuits against the Company or its directors and officers.

Limitations on Liability and Indemnification of Directors and Officers

The certificate of incorporation provides that no director of the Company shall have any personal liability to the Company or its stockholders for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. Amendments to these provisions shall not adversely affect any right or protection of a director of the Company in respect of any act or omission occurring prior to the time of such amendment.

The certificate of incorporation further provides that the Company indemnify directors and officers to the fullest extent permitted by law. The Company is also expressly authorized to advance certain expenses (including, without limitation, attorneys’ fees) to its directors and officers and to maintain insurance, at its expense, to protect itself and/or any director, officer, employee or agent of the Company against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the DGCL.

In addition, the Company entered into separate indemnification agreements with its directors and officers. These agreements, among other things, requires the Company to indemnify its directors and officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or officer in any action or proceeding arising out of their services as one of the Company’s directors or officers or any other company or enterprise to which the person provides services at the Company’s request.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in the Company’s name to procure a judgment in its favor, also known as a derivative action; provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates.
