Description of Registrant's Securities

Endurance International Group Holdings, Inc. (the “Company,” “we,” “us” or “our”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: our common stock, par value $0.0001 per share.

The general terms and provisions of our common stock are summarized below. This summary is based upon, and is qualified by reference to, our restated certificate of incorporation, our amended and restated bylaws and applicable provisions of Delaware corporate law. This summary does not purport to be complete. You should read our restated certificate of incorporation and amended and restated bylaws, each of which is incorporated by reference as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.

Our authorized capital stock consists of 500,000,000 shares of common stock and 5,000,000 shares of preferred stock.

Voting Rights. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights.

Except as may be otherwise provided by applicable law, our restated certificate of incorporation or our amended and restated bylaws, the authorization of any action or the transaction of any business at a duly held meeting of stockholders at which a quorum is present (other than the election of directors) shall be decided by a majority of the votes cast by stockholders entitled to vote thereon.

In connection with an election of directors, a nominee for election in an uncontested election shall be elected by the vote of the majority of votes cast with respect to such nominee at a duly held meeting of stockholders at which a quorum is present, meaning that the number of shares voted for such nominee must exceed the number of shares voted against such nominee. A nominee for election in a contested election shall be elected by a plurality of the votes cast by stockholders entitled to vote thereon at a duly held meeting of stockholders at which a quorum is present.

Dividends. Holders of common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of any series of preferred stock that we may designate and issue in the future.

Liquidation and Dissolution. In the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately our net assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Other Rights. Holders of common stock have no preemptive, subscription, redemption or conversion rights.

Under the terms of our restated certificate of incorporation, our board of directors is authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock. The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock.

We have shares of common stock and preferred stock available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of The Nasdaq Global Market. We may utilize these additional shares for a variety of corporate purposes, including for future public offerings to raise additional capital or facilitate corporate acquisitions or for payment as a dividend on our capital stock. The existence of unissued and unreserved common stock and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a controlling interest in our company by means of a merger, tender offer, proxy contest or otherwise. In addition, if we issue preferred stock, the issuance could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation.

We entered into a stockholders agreement, dated October 24, 2013, or the stockholders agreement, with certain holders of our common stock, including investment funds and entities affiliated with Warburg Pincus LLC, whom we refer to as Warburg Pincus, and Goldman, Sachs & Co., whom we refer to as Goldman Sachs. The stockholders agreement contains agreements among the parties with respect to the election of our directors, certain restrictions on the issuance and transfer of shares and certain corporate governance matters. The material terms of the stockholders agreement, a copy of which is incorporated by reference as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and incorporated herein by reference, are described below.

Director Designees; Chairman. Under the terms of the stockholders agreement, investment funds and entities affiliated with Warburg Pincus are entitled to designate up to:

In addition, investment funds and entities affiliated with Goldman Sachs are entitled to designate up to one director to our board of directors for so long as investment funds and entities affiliated with Goldman Sachs hold an aggregate of at least 5,213,194 shares of our common stock, which represents 25% or more of the shares of our common stock that they held immediately following the closing of our initial public offering.

For so long as investment funds and entities affiliated with Warburg Pincus are entitled to designate at least three directors to our board of directors, the directors designated by investment funds and entities affiliated with Warburg Pincus will be entitled to designate the chairman of our board of directors.

Removal of Directors. Any director designated by investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs may be removed with or without cause only by investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs, respectively.

Quorum. For so long as investment funds and entities affiliated with Warburg Pincus have the right to designate at least one director for election to our board of directors and for so long as investment funds and entities affiliated with Goldman Sachs have the right to designate at least one director for election to our board of directors, in each case, a quorum of our board of directors will not exist without at least one director designee of each of Warburg Pincus and Goldman Sachs present at such meeting; provided that if a meeting of our board of directors fails to achieve a quorum due to the absence of a director designee of Warburg Pincus or Goldman Sachs, as applicable, the presence of at least one director designee of Warburg Pincus or

Goldman Sachs, as applicable, will not be required in order for a quorum to exist at the next meeting of our board of directors.

Approval Rights. For so long as investment funds and entities affiliated with Warburg Pincus have the right to designate at least three directors for election to our board of directors, in addition to any other vote required by applicable law, certain actions required or permitted to be taken by our stockholders and certain specified corporate transactions may be effected only with the affirmative vote of 75% of our board of directors, including:

For so long as investment funds and entities affiliated with Goldman Sachs have the right to designate one director for election to our board of directors, the approval of the director designated by investment funds and entities affiliated with Goldman Sachs will be required for amendments to certain agreements with us if such amendments are disproportionately favorable to investment funds and entities affiliated with Warburg Pincus as compared to investment funds and entities affiliated with Goldman Sachs.

Stockholder Action. Our restated certificate of incorporation provides that any action required or permitted to be taken by our stockholders must be taken at a duly called annual or special meeting of such stockholders and may not be taken by any consent in writing by such stockholders. For so long as investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs, collectively, hold a majority of our outstanding capital stock, however, a meeting and vote of stockholders may be dispensed with, and the action may be taken without prior notice and without such meeting and vote if a written consent is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at the meeting of stockholders.

Special Meeting of Stockholders. For so long as Warburg Pincus or Goldman Sachs, or in either case, any affiliate thereof, collectively own shares of our capital stock representing at least a majority of votes that all the stockholders would be entitled to cast in any annual election of directors or class of directors, special meetings of our stockholders may be called only by the affirmative vote of the holders of a majority of the votes that all the stockholders would be entitled to cast in any annual election of directors or class of directors or by our board of directors. At all other times, special meetings of stockholders for any purpose or purposes may be called at any time by only our board of directors, the chairman of our board of directors or our chief executive officer.

Stockholder Nomination of Directors. Our amended and restated bylaws provide that a stockholder must notify us in writing of any stockholder nomination of a director not earlier than the 120th day and not later than the 90th day prior to the first anniversary of the preceding year’s annual meeting of stockholders; provided, that if the date of the annual meeting is advanced by more than 20 days, or delayed by more than 60 days from such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the 120th day prior to the date of such annual meeting and not later than the close of business on the later of (x) the 90th day prior to the date of such meeting and (y) the 10th day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs. These requirements do not apply to any directors entitled to be elected by the holders of preferred stock, any directors elected in accordance with our bylaws by the board of directors to fill a vacancy or newly-created directorship, or any directors designated pursuant to the terms of the stockholders agreement.

Supermajority Voting. The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. For so long as investment funds and entities affiliated with Warburg Pincus have the right to designate at least three directors for election to our board of directors, the affirmative vote of 75% our board of directors is required to amend our restated certificate of incorporation and our amended and restated bylaws or enter into certain specified corporate transactions, in addition to any other vote required by applicable law.

Staggered Board; Removal of Directors. Our restated certificate of incorporation and our amended and restated bylaws divide our board of directors into three classes with staggered three-year terms. In addition, a director may be removed by stockholders only for cause by the affirmative vote of the holders of at least 75% of the votes that all of our stockholders would be entitled to cast in an annual election of directors; provided that any director designated by investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs may be removed with or without cause only by investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs, respectively, and for so long as investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs, collectively, hold at least a majority of our outstanding capital stock, our directors, other than a director designated by investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs, may be removed with or without cause by the affirmative vote of the holders of a majority of our outstanding capital stock. Any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office; provided that for so long as investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs have the right to designate at least one director for election to our board of directors, any vacancies will be filled in accordance with the designation provisions set forth in the stockholders agreement.

The classification of our board of directors and the limitations on the removal of directors and filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of our company.

Choice of Forum. Our restated certificate of incorporation provides that the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, any action asserting a claim against us arising pursuant to any provision of the Delaware General Corporation Law, our restated certificate of incorporation or our amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine. The enforceability of choice of forum provisions has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.

Delaware Law. We are subject to Section 203 of the Delaware General Corporation Law. Subject to certain exceptions, Section 203 prevents a publicly held Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

Since the investment funds and entities affiliated with Warburg Pincus and Goldman Sachs became holders of more than 15% of our outstanding common stock in a transaction that was approved by our Board of Directors, the restrictions of Section 203 of the Delaware General Corporation law would not apply to a business combination transaction with any investment funds or entities affiliated with either Warburg Pincus or Goldman Sachs. In addition, our restated certificate of incorporation expressly exempts investment funds and entities affiliated with either Warburg Pincus or Goldman Sachs from the applicability of Section 203 of the Delaware General Corporation Law.
