 DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES

EXCHANGE ACT OF 1934, AS AMENDED

The following summary of the material terms of our Class A common stock is not intended to be a complete summary of the rights and preferences of such securities, and is qualified by reference to the Second Amended and Restated Certificate of Incorporation (our “Certificate of Incorporation”) and the Amended and Restated Bylaws (our “Bylaws”), each of which is an exhibit incorporated by reference into the Annual Report on Form 10-K of which this exhibit is a part. This summary is qualified in its entirety to those documents.

Authorized and Outstanding Stock

Our Certificate of Incorporation authorizes the issuance of 111,000,000 shares of capital stock, $0.0001 par value per share, consisting of (a) 110,000,000 shares of common stock, including 100,000,000 shares of Class A common stock and 10,000,000 shares of Class F common stock, and (b) 1,000,000 shares of preferred stock (the “Preferred Stock”).

As of March 5, 2021, there were approximately 32,873,457 shares of Class A common stock outstanding, and excludes, as of such date:

As of March 5, 2021, there were no shares of Class F common stock outstanding, and no shares of Preferred Stock outstanding. The outstanding shares of common stock are duly authorized, validly issued, fully paid and non-assessable.

Class A Common Stock

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of Preferred Stock, the holders of Class A common stock possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of Class A common stock and Class F common stock are entitled to one vote per share, voting together as a single class, on matters to be voted on by stockholders.

Dividends

Subject to the rights of holders of Preferred Stock, holders of Class A common stock will be entitled to receive such dividends, if any, as may be declared from time to time by the Board in its discretion out of funds legally available therefor. We have not paid any cash dividends on the Class A common stock to date. We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay cash dividends for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of the board of directors (the “Board”) and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the Board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness incurred.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the Class A common stock, together with holders of Class F common stock, will be entitled to receive an amount of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied, ratably in proportion to the number of shares of Class A common stock (on an as-converted basis with respect to the Class F common stock) held.

Preemptive or Other Rights

Our stockholders have no preemptive or other subscription rights and there are no sinking fund, redemption provisions or conversion provisions applicable to Class A common stock.

Class A Common Stock as Potentially Limited by Issuance of Preferred Stock

The Certificate of Incorporation provides that shares of Preferred Stock may be issued from time to time in one or more series. The Board is authorized to fix the voting rights, if any, designations, powers and preferences, the relative, participating, optional or other special rights, and any qualifications, limitations and restrictions thereof, applicable to the shares of each series of Preferred Stock. The Board is able to, without stockholder approval, issue Preferred Stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Class A common stock and could have anti-takeover effects. The ability of our Board to issue Preferred Stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of the Company or the removal of existing management.

Certain Anti-Takeover Provisions of Delaware Law and our Certificate of Incorporation and Bylaws

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

A “business combination” includes a merger or sale of more than 15% of our assets. However, the above provisions of Section 203 do not apply if:

Our authorized but unissued capital 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 capital stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exclusive forum for certain lawsuits

Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing such suit will be deemed to have consented to service of process on such stockholder’s counsel. In addition, our Bylaws require that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, unless and until our Bylaws are amended in this respect, the exclusive forum provision shall not apply to claims seeking to enforce any liability or duty created by the Exchange Act. Any person or entity purchasing or otherwise acquiring any interest in our shares of common stock shall be deemed to have notice of and to have consented to these provisions of our Certificate of Incorporation and Bylaws. In addition, Section 22 of the Securities Act provides that federal and state courts have concurrent jurisdiction over lawsuits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. To the extent the exclusive forum provision restricts the courts in which claims arising under the Securities Act may be brought, there is uncertainty as to whether a court would enforce such a provision. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Special meetings of stockholders

Our Bylaws provide that special meetings of our stockholders may be called only by a majority vote of our Board, by our Chief Executive Officer or by our Chairman of the Board.

Advance notice requirements for stockholder proposals and director nominations

Our Bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders must provide timely notice of their intent in writing. To be timely, a stockholder’s notice will need to be received by the Company secretary at our principal executive offices not later than the close of business on the 90^th day nor earlier than the opening of business on the 120^th day prior to the anniversary of the immediately preceding annual meeting of stockholders. Pursuant to Rule 14a-8 of the Securities Act, proposals seeking inclusion in our annual proxy statement must comply with the notice periods contained therein. Our Bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

No action by written consent

Our Certificate of Incorporation provides that any action required or permitted to be taken by our stockholders must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders.

Classified Board of Directors

Our Certificate of Incorporation provides that our Board is divided into two classes, Class I and Class II, with members of each class serving staggered two-year terms and that the authorized number of directors may be changed only by resolution of the Board. As a result, in most circumstances, a person can gain control of our Board only by successfully engaging in a proxy contest at two or more annual meetings.

There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors within the class of directors up for election.

Subject to the terms of any Preferred Stock, any or all of the directors may be removed from office at any time, but only for cause and only by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class. Any vacancy on our Board, including a vacancy resulting from an enlargement of our Board, may be filled only by vote of a majority of our directors then in office.

Our Transfer Agent

The transfer agent for our common stock is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust Company in its role as transfer agent, its agents and each of its stockholders, directors, officers and employees against all liabilities, including judgments, costs and reasonable counsel fees that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

Rule 144

Pursuant to Rule 144, a person who has beneficially owned restricted shares of our common stock for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted shares of our common stock for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

Following the closing of the Business Combination, we were no longer a shell company, and so, once the conditions set forth in the exceptions listed above are satisfied, Rule 144 will become available for the resale of applicable restricted securities.

Lock-Up Restrictions

Registration Rights Agreement

The Registration Rights Agreement, dated as of November 20, 2020, includes a lock-up period which provides that certain stockholders party thereto shall not transfer any shares of Class A common stock issued to such stockholders as part of the closing share consideration that may have been issued to such stockholders prior to the earlier of (i) the first anniversary of the closing of the Business Combination, (ii) the date, following the 180^th day after the date of the closing, on which the volume weighted average per share price (“VWAP”) of common stock equals or exceeds $15.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), (iii) the date, following the 270^th day after the closing, on which the VWAP of common stock equals or exceeds $13.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), or (iv) the Company’s completion of a liquidation, merger, stock exchange or other similar transaction that results in all of the Onyx stockholders having the right to exchange their shares of common stock for cash, securities or other property.
