 Attention: Jesse A. Cohn 

Ladies and Gentlemen: 
 This letter (this
“Agreement”) constitutes the agreement between (a) Twitter, Inc. (the “Company”) and (b) Elliott Investment Management L.P., a Delaware limited partnership, Elliott Associates, L.P., a Delaware limited
partnership, and Elliott International, L.P., a Cayman Islands limited partnership (each, an “Elliott Party” and collectively, the “Elliott Parties”). The Elliott Parties and each Affiliate (as defined below)
of each Elliott Party are collectively referred to as the “Elliott Group.” The Company and the Elliott Parties are collectively referred to as the “Parties.” 

1.    New Director Appointments. As promptly as practicable following the execution of this Agreement, the Company
and the Board of Directors of the Company (the “Board”) will take all necessary actions to increase the size of the Board to the extent necessary in connection with the appointments contemplated by this paragraph 1. Subject to the
last sentence of this paragraph 1, the Company and the Board will take all action necessary so that (a) as promptly as practicable following the execution of this Agreement, Jesse Cohn (the “Elliott Designee”) will be appointed
to the Board as a Class II director with a term expiring at the Company’s 2021 annual meeting of stockholders (the “2021 Annual Meeting”); (b) as promptly as practicable following the date of consummation of the
transactions contemplated by the Investment Agreement, dated as of March 9, 2020, between the Company and Silver Lake Partners V DE (AIV), L.P., Egon Durban (the “SLP Designee”) will be appointed to the Board as a
Class III director with a term expiring at the Company’s 2022 annual meeting of stockholders; and (c) as promptly as practicable following the completion of the Company’s director search process, one additional Independent
director selected by the Company will be appointed to the Board as a Class II director with a term expiring at the 2021 Annual Meeting (such person, together with the Elliott Designee and the SLP Designee, the “New Directors”).
The appointment of each New Director to the Board will be subject to and contingent upon the provision by such New Director of any information the Company reasonably requires to complete its customary onboarding procedures for Board members
(including a customary background check and review of such New Director’s independence and potential conflicts). 

 2.    2020 Annual Meeting Director Slate. The Company and the
Board will nominate Omid Kordestani, Ngozi Okonjo-Iweala and Bret Taylor for re-election as Class I directors at the Company’s 2020 annual meeting of stockholders (the “2020 Annual
Meeting”) (or, if any such person is no longer willing or able to serve on the Board or so stand for re-election, an alternative director candidate nominated by the Board for election as a
Class I director), and the Board will recommend that the Company’s stockholders vote, and will solicit proxies, in favor of the election of, and otherwise support such persons for election, in a manner consistent with the Company’s
past practice. 
 3.    Replacement Elliott Designee. Subject to paragraph 4, during the Cooperation Period (as
defined below), if the Elliott Designee is unable or unwilling to serve as a director, resigns as a director, is removed as a director or ceases to be a director for any other reason (in each case, other than in the circumstances described in
paragraph 4), as promptly as practicable, the Elliott Parties and the Company will cooperate to identify (and the Board will appoint as promptly as practicable thereafter) another person reasonably acceptable to the Company and the Elliott
Parties (a “Successor Elliott Designee”) to serve as a Class II director in place of the Elliott Designee for the remainder of the Elliott Designee’s term. Upon becoming a member of the Board, the Successor Elliott
Designee will be deemed to be the Elliott Designee for all purposes of this Agreement, and succeed to all of the rights and privileges, and will be bound by the terms and conditions, of the Elliott Designee under this Agreement. 

4.    Resignation of the Elliott Designee. The Company’s obligations under paragraph 3 will terminate upon the
earlier of such time as: (a) the Elliott Group beneficially owns shares of the Company’s common stock (which shares are determined to be Net Long Shares (as defined below)) representing in the aggregate less than 2.0 percent of the
Company’s then-outstanding common stock; (b) any member of the Elliott Group or any other Restricted Person (as defined below) breaches in any material respect any of the terms of this Agreement, upon five Business Days’ written
notice by the Company to the Elliott Parties if such breach has not been cured within such notice period, provided that the Company is not in material breach of this Agreement at the time such notice is given or prior to the end of the notice
period; or (c) any member of the Elliott Group or any other Restricted Person submits any director nominations for election at any meeting of the Company’s stockholders. In addition, upon the occurrence of any event described in clause
(b) or (c) of the previous sentence, the Elliott Designee will resign from the Board concurrently with such occurrence, it being understood that any Successor Elliott Designee that is not a Restricted Person will be required to execute a
customary conditional resignation letter as a condition to his or her appointment, or nomination for election, to the Board to effect the foregoing. 

5.    Withdrawal of Nomination Notice. Effective as of the execution of this Agreement, the Elliott Group will be
deemed to have irrevocably withdrawn its notice of nomination to the Company dated as of February 21, 2020, in respect of its intention to nominate, and to solicit proxies for the election of, four individuals as director candidates to the
Board at the 2020 Annual Meeting. 
 6.    Company Policies. The Parties acknowledge that the Elliott Designee,
upon appointment to the Board, will be governed by the same protections and obligations regarding confidentiality, conflicts of interest, related party transactions, fiduciary duties, codes of conduct,

  
 -2- 

 
trading and disclosure policies, expense reimbursement, director resignation, and other governance guidelines and policies of the Company as are applicable to the independent directors of the
Company generally, as they may be modified from time to time (collectively, the “Company Policies”), and will have the same rights and benefits with respect to insurance, indemnification, compensation and reimbursement as are
applicable to the independent directors of the Company generally, as they may be modified from time to time. The Company hereby agrees that Mr. Cohn may provide confidential information of the Company to members of the Elliott Group for the
purpose of assisting Mr. Cohn in his role as a director of the Company and related compliance matters for the Company and the Elliott Group, subject to, and solely in accordance with the terms of, a customary confidentiality agreement among the
Elliott Parties and the Company restricting the disclosure and use by the members of the Elliott Group and other Restricted Persons of such confidential information, and the Elliott Parties and the Company will cooperate to prepare and enter into
such agreement as promptly as practicable following the execution and delivery of this Agreement. 
 7.    New
Director Agreements, Arrangements and Understandings. Each Elliott Party agrees that neither it nor any other member of the Elliott Group or any other Restricted Person will (a) pay any compensation to any New Director
(including any Successor Elliott Designee) for such person’s service on the Board or any committee thereof; or (b) have any agreement, arrangement or understanding, written or oral, with any New Director (including any Successor Elliott
Designee) regarding such person’s service on the Board or any committee thereof (including pursuant to which such New Director will be compensated for his or her service as a director on, or nominee for election to, the Board or any committee
thereof). The Company acknowledges that no Company Policy will be violated by the Elliott Designee receiving indemnification and/or reimbursement of expenses from the Elliott Parties or their respective Affiliates if the Elliott Designee neither
accepts nor receives compensation from the Elliott Parties or their respective Affiliates for the Elliott Designee’s service as a director of the Company. 

8.    Management Structure Committee. As promptly as practicable following the execution of this Agreement, the
Board will take all necessary action to (a) form a committee of the Board whose charter will be in the form set forth on Exhibit A hereto (the “Management Structure Committee Charter”), (b) appoint as the only members of the committee
each of the Elliott Designee, the SLP Designee, Patrick Pichette and two other Independent directors, (c) maintain the size of the committee at five members and (d) cause such committee to remain in place until it has satisfied its
responsibilities in accordance with the Management Structure Committee Charter. 
 9.    Voting Commitment. At
each annual or special meeting of the Company’s stockholders or action by written consent during the Cooperation Period, the Elliott Parties will, and will cause the other members of the Elliott Group to, cause all Voting Securities that such
Person has the right to vote as of the applicable record date, to be present in person or by proxy for quorum purposes and to be voted at any meeting of stockholders of the Company or at any adjournments or postponements thereof, and to consent in
connection with any action by written consent in lieu of a meeting, (a) in favor of the election of each person nominated by the Board for election as a director; (b) against the election as director of any person that is not approved and
recommended by the Board for election at any such meeting or through any such written 

  
 -3- 

 
consent, (c) against any proposals or resolutions to remove any member of the Board and (d) in accordance with the recommendation of the Board on all other proposals or business that
may be the subject of stockholder action at such meeting or action by written consent. Notwithstanding the foregoing, the members of the Elliott Group will be permitted to vote in their sole discretion on any proposals related to any Extraordinary
Transaction (as defined below). 
 10.    Cooperation Period. During the period from the date of this Agreement
until 11:59 p.m., Pacific time, on the day that is 30 days prior to the last day of the advance notice period established by the Company’s bylaws for stockholders of the Company to deliver notice of director nominations for the 2021 Annual
Meeting (such period, the “Cooperation Period”), the Elliott Parties will not, and will cause the other members of the Elliott Group and each of their respective principals, directors, general partners, officers, employees and
agents and representatives acting on their behalf (collectively, the “Restricted Persons”), not to, directly or indirectly, without the prior written consent of the Board:

Company or assets of the Company, or rights or options to acquire any securities of the Company or assets of the Company, or engage in any swap or hedging transactions or other derivative agreements of any nature with respect to securities of the
Company, in each case if such acquisition, offer, agreement or transaction would result in the Elliott Group having aggregate beneficial ownership in excess of 4.9 percent of any class of Voting Securities outstanding at such time, or aggregate
economic exposure to more than 7.5 percent of the Voting Securities outstanding at such time; 
 (b)    (i) seek,

exchange offer, merger, amalgamation, consolidation, acquisition, business combination, recapitalization, consolidation, restructuring, liquidation, dissolution or similar extraordinary
transaction involving the Company, any of its subsidiaries or any of their respective securities or assets (each, an “Extraordinary Transaction”) (it being understood that the foregoing will not restrict a Restricted Person from
tendering shares, receiving payment for shares or otherwise participating in any such transaction on the same basis as other stockholders of the Company); 

(f)    make any public proposal with respect to (i) any change in structure of the Board (including the classified

 -5- 

 
Company’s prior written consent that are supportive of the Company’s management and Board, or that are otherwise consistent with the Press Release (as defined below) or the provisions

its equity securities, where the aggregate consideration payable by the Company or the proceeds to the Company of such issuance, exceeds $4 billion, in each case that is proposed by a person other than the Elliott Group and that was not
encouraged, facilitated or solicited by any Restricted Person); 
 (l)    institute, solicit, assist or join, as a
party, any litigation, arbitration or other proceeding against or involving the Company, its Affiliates or any of their respective current or former directors or officers (including derivative actions), except that the foregoing will not prevent any

such notice is given or at any time prior to the end of the notice period, (ii) following such time as neither Mr. Cohn nor any other Restricted Person is a member of the Board, the announcement by the Company of its entry into a
definitive agreement with respect to any Extraordinary Transaction that would result in the acquisition by any person or group of more than 50% of the Company common stock and which Extraordinary Transaction was not encouraged, facilitated or
solicited by any Restricted Person, (iii) following such time as neither Mr. Cohn nor any other Restricted Person is a member of the Board, the commencement of any tender or exchange offer (by a person other than any member of the Elliott
Group and 

  
 -6- 

 
which offer was not encouraged, facilitated or solicited by any Restricted Person) which, if consummated, would constitute an Extraordinary Transaction that would result in the acquisition by any
person or group of more than 50% of the Company common stock, where the Company files a Schedule 14D-9 (or any amendment thereto), other than a “stop, look and listen” communication by the Company
pursuant to Rule 14d-9(f) promulgated under the Exchange Act, that does not recommend that the Company’s stockholders reject such tender or exchange offer, and (iv) such time as the Elliott Designee
resigns from, or otherwise ceases to be a member of, the Management Structure Committee following a material breach by the Company or the Board of the Management Structure Committee Charter, if the Elliott Parties have provided the Company five
Business Days’ written notice of such breach and it has not been cured within such notice period, provided that none of the Elliott Parties is in material breach of this Agreement at the time such notice is given or prior to the end of the
notice period or at such time as the Elliott Designee resigns from, or otherwise ceases to be a member of, the Management Structure Committee. Notwithstanding anything to the contrary in this Agreement, nothing in this paragraph 10, paragraph 13 or
elsewhere in this Agreement, will prohibit or restrict the Elliott Designee in his or her personal capacity as a director from exercising his or her rights and fiduciary duties as a director of the Company or restrict his or her discussions solely
among other members of the Board and/or management, advisors, representatives or agents of the Company; provided that any such discussions are limited to communications in his or her personal capacity as a director.

have been identified by one of the foregoing to the Elliott Parties as appropriate contacts and, to the extent that the specific meeting or communication is approved in writing in advance and coordinated by the Company’s General Counsel, other
personnel of the Company, so long as such communications would not reasonably be expected to require any public disclosure of such communications or the content thereof; (b) taking any action necessary to comply with any law, rule or regulation
or any action required by any governmental or regulatory authority or stock exchange that has, or may have, jurisdiction over such member of the Elliott Group (so long as such requirement did not arise as a result of a breach by a Restricted Person
of this Agreement); (c) privately communicating to any of their investors non-confidential information regarding the Company, but only if such communications are subject to reasonable confidentiality
obligations and are not otherwise reasonably expected to be publicly disclosed; (d) making any public or private statement or announcement with respect to any Extraordinary Transaction that is an acquisition by the Company of another Person, or
the issuance by the Company of its equity securities, where the aggregate consideration payable by the Company or the proceeds to the Company of such issuance, exceeds $4 billion; (e) granting any liens or encumbrances on any claims or
interests in favor of a bank or broker-dealer or prime broker holding such claims or interests in custody or prime brokerage in the ordinary course of business, which lien or encumbrance is released upon the transfer of such claims or interests in
accordance with the terms of the custody or prime brokerage agreement(s), as applicable; or (f) negotiating, evaluating and/or trading, directly or indirectly, in any index, exchange traded fund, benchmark or other basket of securities which

Mr. Cohn shall refrain from making, and shall cause its respective Affiliates and its and their respective principals, managing directors, directors, members, general partners, officers and employees not to make or cause to be made any
statement or announcement (including any statement or announcement that can reasonably be expected to become public) that constitutes an ad hominem attack on, or that otherwise disparages, defames, slanders, impugns or is reasonably likely to damage
the reputation of, (a) in the case of any such statements or announcements by any of the Elliott Parties, the Elliott Designee or their related parties: the Company and its Affiliates or any of their current or former officers, directors or
employees; and (b) in the case of any such statements or announcements by the Company or its related parties: the Elliott Parties and their current or former principals, directors, members, general partners, officers or employees. The foregoing
shall not restrict the ability of any person to comply with applicable law, any subpoena or other legal process or respond to a request for information from any governmental authority with jurisdiction over the party. 

13.    Impartiality; No Influence. During the Cooperation Period and, if longer, while an Elliott Designee
serves as a member of the Board, none of the Elliott Parties, any other member of the Elliott Group or any other Restricted Person will comment on or influence, or attempt to influence, directly or indirectly, any Company policies or rules, or
policy or rule enforcement decisions with respect to the independence and impartiality of decisions related to content moderation on the Twitter platform or access to Twitter user data. 

14.    Compliance with this Agreement. The Elliott Parties will cause the members of the Elliott Group and the
other Restricted Persons (including any Elliott Designee that is a Restricted Person) to comply with the terms of this Agreement applicable to such Persons, and will be responsible for any breach of such terms of this Agreement applicable to any

without proof of actual damages; (b) the Party against whom specific performance is sought will not plead in defense that there would be an adequate remedy at law; and (c) the Party against whom specific performance is sought agrees to
waive any applicable right or requirement that a bond be posted. Such remedies will not be the exclusive remedies for a breach of this Agreement, but will be in addition to all other remedies available at law or in equity. 

21.    Entire Agreement; Binding Nature; Assignment; Waiver. This Agreement constitutes the only agreement between
the Parties with respect to the subject matter of this Agreement and it supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written. This Agreement binds, and will inure to the benefit of, the Parties and
their respective successors and permitted assigns. No Party may assign or otherwise transfer either this Agreement or any of its rights, interests, or obligations under this Agreement without the prior written approval of the other Party. Any
purported transfer requiring consent without such consent is void. No amendment, modification, supplement or waiver of any provision of this Agreement will be effective unless it is in writing and signed by the affected Party, and then only in the
specific instance and for the specific purpose stated in such writing. Any waiver by any Party of a breach of any provision of this Agreement will not operate as or be construed to be a waiver of any other breach of such provision or of any breach
of any other provision of this

Agreement. The failure of a Party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that Party of the right to
insist upon strict adherence to that term or any other term of this Agreement in the future. 

22.    Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent
jurisdiction, then the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement that is held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held
invalid or unenforceable, and this Agreement will otherwise be construed so as to effectuate the original intention of the Parties reflected in this Agreement. The Parties further agree to replace such invalid or unenforceable provision of this
Agreement with a valid and enforceable provision that will achieve, to the extent possible, the purposes of such invalid or unenforceable provision. 

23.    Governing Law; Forum. This Agreement is governed by, and will be construed in accordance with, the laws of
the State of Delaware. Each of the Parties (a) irrevocably and unconditionally consents to the exclusive personal jurisdiction and venue of the Court of Chancery of the State of Delaware and any appellate court thereof (unless the federal
courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware and any appellate court thereof will have exclusive personal jurisdiction); (b) agrees that it will not attempt to
deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (c) agrees that it will not bring any action relating to this Agreement or otherwise in any court other than the such courts; and
(d) waives any claim of improper venue or any claim that those courts are an inconvenient forum. The Parties agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in
paragraph 26 or in such other manner as may be permitted by applicable law, will be valid and sufficient service thereof. 

24.    Waiver of Jury Trial. EACH OF THE PARTIES, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH
COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT, OR ANY OF THE TRANSACTIONS
CONTEMPLATED THEREBY, OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM. No Party will seek to consolidate, by counterclaim or otherwise, any action in which a jury trial has been waived with any
other action in which a jury trial cannot be or has not been waived. 
 25.    Third Party Beneficiaries. This
Agreement is solely for the benefit of the Parties and is not enforceable by any other Person. 
 26.    Notices.
All notices and other communications under this Agreement must be in writing and will be deemed to have been duly delivered and received (a) four Business Days after being sent by registered or certified mail, return receipt requested, postage
prepaid; (b) one Business Day after being sent for next Business Day delivery, fees prepaid, via a reputable nationwide overnight courier service; (c) immediately upon delivery by hand or by fax; or (d) on the date sent by email

 MARCH 9, 2020 

Twitter, Inc. Announces Partnership With Silver Lake and Elliott Management 

Silver Lake to make $1 Billion Investment 

Board Authorizes $2 Billion Share Repurchase Program 

Enters into Cooperation Agreement with Elliott Management 

Further Strengthens Twitter Board by Appointing Egon Durban and Jesse Cohn as Directors, Confirms 

Search for a Third New Independent Director with Technology Expertise 

Forms New Committee to Build on Regular Evaluation of Leadership and Governance Structure 

SAN FRANCISCO, California – Twitter, Inc. (NYSE: TWTR) today announced that Silver Lake, a global leader in technology investing, will make a
$1 billion investment in Twitter. Twitter also entered into a Cooperation Agreement with Elliott Management Corporation (“Elliott”), an investment firm whose affiliated funds own approximately 4% percent of the Company’s common
stock and economic equivalents. The Company expects to use Silver Lake’s investment, together with cash on hand, to fund a $2 billion share repurchase program that will be executed over time. 

In connection with the investment and the Cooperation Agreement, Egon Durban, co-CEO and managing partner of Silver
Lake, and Jesse Cohn, partner at Elliott, will be appointed to the Twitter Board of Directors. In addition, the Twitter Board will continue the process of identifying a third new independent director, focusing on candidates that reflect the
diversity of the Twitter service and also possess deep technology and AI expertise. 
 Patrick Pichette, lead independent director of the Twitter Board,
said, “Twitter has undergone remarkable change over the last several years. We are deeply proud of our accomplishments and confident we are on the right path with Jack’s leadership and the executive team. As a Board, we regularly review
and evaluate how Twitter is run, and while our CEO structure is unique, so is Jack and so is this Company. To continue to ensure strong governance, we are pleased to create a temporary Board committee that will build on our regular evaluation of
Twitter’s leadership structure. This committee, which I will chair, will provide a fresh look at our various structures, and report the findings to our Board on an ongoing basis. In an environment where certainty is scarce, I can say with
certainty that today we have taken steps to meaningfully strengthen what is already a world-class Board.” 
 Twitter will further strengthen the Board
through the additions of Mr. Durban and Mr. Cohn. As one of the most respected technology investors in the world, Mr. Durban brings unparalleled operational knowledge in technology. Mr. Cohn is one of the most prominent active
investors in public technology companies and brings outstanding industry, capital markets, and governance experience. The Company is also looking to appoint a third new independent director with technology expertise in the near term. 

Jack Dorsey, co-founder and CEO, said, “Twitter serves the public conversation, and our purpose has never been
more important. Silver Lake’s investment in Twitter is a strong vote of confidence in our work and our path forward. They are one of the most respected voices in technology and finance and we are fortunate to have them as our new partner and as
a member of our Board. We welcome the support of Egon and Jesse, and look forward to their positive contributions as we continue to build a service that delivers for customers, and drives value for stakeholders.” 

 Egon Durban, co-CEO and managing partner of Silver Lake said,
“Twitter’s revolutionary platform is a cornerstone of the public discourse. We are impressed by Jack’s tireless work over the last few years to solidify the leadership team, improve the product and strengthen the Company. We are
excited to partner with Twitter as an investor and a member of the Board. Jack is a visionary leader, and a critical force behind Twitter’s ongoing evolution and growth. I look forward to working alongside the entire Board and the executive
team to drive Twitter’s long-term innovation and success.” 
 Jesse Cohn, partner at Elliott Management, said, “Twitter is one of the most
important platforms in the global dialogue, and one of the most innovative and unique technology companies in the world. We are pleased to have worked collaboratively with Twitter on this constructive engagement. We invested in Twitter because we
see a significant opportunity for value creation at the Company. I am looking forward to working with Jack and the Board to help contribute to realizing Twitter’s full potential.” 

Twitter also shared its ambitions for two metrics which are important measures of the Company’s progress. The ambition in 2020 and beyond is to grow mDAU
at 20% or more, and looking beyond 2020, to accelerate revenue growth on a year-over-year basis and gain share in the digital advertising market as Twitter continues to invest to drive growth. More details on these ambitions will be shared at an
analyst day in the fall of 2020. 
 Twitter is also reinforcing its commitment to impartiality in the development and enforcement of its policies and rules.
As such, per the terms of the Cooperation Agreement, neither Elliott nor Silver Lake will comment on or influence, or attempt to influence, directly or indirectly, any Twitter policies or rules, or policy or rule enforcement decisions, related to
the Twitter platform. Elliott and Silver Lake further commit to, and emphasize the importance of, maintaining the independence and impartiality of the Twitter platform and its rules and enforcement. 

Silver Lake Partnership with Twitter 
 Silver Lake’s
mission is to build and grow great companies by partnering with world-class management teams. Leveraging insights from a global portfolio and deep technology experience, upon invitation by the Company, Silver Lake and its team of operating
professionals will collaborate with Twitter on various operational initiatives with primary focus on accelerating growth and product innovation. 
 Silver
Lake agreed to purchase $1 billion in aggregate principal amount of the Company’s 0.375% Convertible Senior Notes due 2025. Details of the notes, and the related agreements, will be filed on Form 8-K
with the Securities and Exchange Commission. Silver Lake also offered to provide the Company with certain advisory, strategic and consulting services. 

Share Repurchase Program 
 The Company will use the
proceeds of the Silver Lake investment, as well as cash on hand, to repurchase up to $2 billion of its own shares over time. 
 Management Structure
Committee of the Board 
 The Board has formed an independent five-person committee that will build on the Board’s regular evaluation of
Twitter’s leadership structure. Mr. Pichette will be the Committee’s chair. Two additional independent current board members, along with Mr. Durban and Mr. Cohn, will comprise this committee. The Committee will also evaluate
the CEO succession plan with the CEO and make 

 
recommendations consistent with corporate governance best practices with respect to the elimination of the Company’s staggered board. The Committee will report on its evaluation to the Board
any considerations or recommended changes and will conclude its work and share the results publicly before the end of the year. 
 Cooperation Agreement

 The full Cooperation Agreement between Twitter and Elliott will be filed on a Form 8-K with the Securities and
Exchange Commission. Elliott and certain of its affiliates have also agreed to a customary standstill, voting and other provisions until one month before notices of director nominations are due in connection with the Company’s 2021 Annual
Meeting of Stockholders. 
 Advisors 
 Goldman
Sachs & Co. LLC and Allen & Company LLC are serving as financial advisors to Twitter and Wilson Sonsini Goodrich & Rosati is serving as legal counsel. Goldman Sachs also served as financial advisor to Twitter for Silver
Lake’s convertible investment.

 Exhibit 4.1 

DESCRIPTION OF REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934 

The following summary describes the capital stock of Organogenesis Holdings Inc. (the “Company,” “we,” “us,” and
“our”) and the material provisions of our restated certificate of incorporation and our amended and restated bylaws, the amended and restated registration rights agreement to which we and certain of our stockholders are parties and of the
General Corporation Law of the State of Delaware (the “DGCL”). Because the following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to our restated
certificate of incorporation, amended and restated bylaws, and amended and restated registration rights agreement, copies of which are incorporated by reference as exhibits to our Annual Report on Form 10-K.

 As of December 31, 2019, we had Class A common stock, $0.0001 par value per share, registered under Section 12 of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), and listed on The Nasdaq Capital Market under the trading symbol “ORGO.”

Authorized and Outstanding Capital Stock 
 Our restated
certificate of incorporation authorizes the issuance of 421,000,000 shares of capital stock, consisting of (i) 420,000,000 shares of common stock, including 400,000,000 shares of Class A common stock, par value $0.0001 per share
(the “Class A Common Stock”) and 20,000,000 shares of Class B common stock, par value $0.0001 per share (the “Class B Common Stock”), and (ii) 1,000,000 shares of preferred stock, par value
$0.0001 per share. As of December 31, 2019, there were 104,870,886 shares of Class A common stock outstanding, no shares of Class B common stock were outstanding and no shares of preferred stock were outstanding. The
outstanding shares of our Class A 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 and will at all times vote together as one class on all matters submitted to a vote of the stockholders. Holders
of our Class A common stock are entitled to one vote per share on matters to be voted on by stockholders. 
 Dividends 

Holders of Class A common stock will be entitled to receive such dividends and other distributions, if any, as may be declared from time to time by the
board of directors (the “Board”) in its discretion out of funds legally available therefor and shall share equally on a per share basis in such dividends and distributions. 

Liquidation, Dissolution and Winding Up 
 In the
event of the voluntary or involuntary liquidation, dissolution, or winding-up of the Company, holders of Class A common stock will be entitled to receive an equal amount per share of
all of our assets of whatever kind available for distribution to stockholders, after the rights of our creditors have been satisfied. 
 Preemptive or
Other Rights 
 Our stockholders have no preemptive, conversion or other subscription rights and there will be no sinking fund or redemption
provisions applicable to our Class A common stock. 
 Election of Directors 

Under our restated certificate of incorporation, the Board consists of a single class, with all directors serving until our next annual meeting. There is no
cumulative voting with respect to the election of directors, with the result that directors will be elected by a majority of the votes cast at an annual meeting of stockholders by holders of our Class A common stock. 

 Preferred Stock 

Our restated certificate of incorporation provides for 1,000,000 authorized shares of preferred stock. The existence of authorized but unissued shares of
preferred stock may enable our Board to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our
Board were to determine that a takeover proposal is not in the best interests of us or our stockholders, our Board could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions
that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our restated certificate of incorporation grants our Board broad power to establish the rights and preferences of
authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of Class A common stock. The issuance may also
adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us. 

Registration Rights 
 We and certain of our stockholders
are party to an amended and restated registration rights agreement. The stockholders party to the amended and restated registration rights agreement and their permitted transferees are entitled to certain registration rights described therein. Among
other things, pursuant to the amended and restated registration rights agreement, these stockholders are entitled to participate in three demand registrations, and will also have certain “piggyback” registration rights with respect to
registration statements, subject to cut-back provisions. We will bear the expenses incurred in connection with the filing of any such registration statements, other than certain
underwriting discounts, selling commissions and expenses related to the sale of shares. We filed a re-sale registration on Form S-3 pursuant to the
terms of the amended and restated registration rights agreement on December 24, 2018 that was declared effective by the SEC on February 12, 2019. 

Certain Anti-Takeover Provisions of Delaware Law, Our Restated Certificate of Incorporation and Amended and Restated Bylaws 

We are a corporation incorporated under the laws of the State of Delaware, and are subject to the provisions of Section 203 of the DGCL, which we refer to
as “Section 203,” regulating corporate takeovers. 
 Section 203 prevents certain Delaware corporations, under certain circumstances,
from engaging in a “business combination” with: 
  

	 	•	 	 a stockholder who owns fifteen percent (15%) or more of our outstanding voting stock (otherwise known as an
“interested stockholder”); 

  

	 	•	 	 an affiliate of an interested stockholder; or 

 

	 	•	 	 an associate of an interested stockholder, for three years following the date that the stockholder became an
interested stockholder. 

 A “business combination” includes a merger or sale of more than ten percent (10%) of our assets.
However, the above provisions of Section 203 do not apply if: 
  

	 	•	 	 our Board approves the transaction that made the stockholder an “interested stockholder,” prior to the
date of the transaction; 

  

	 	•	 	 after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that
stockholder owned at least eighty-five percent (85%) of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of Class A common stock; or 

 

	 	•	 	 on or subsequent to the date of the transaction, the business combination is approved by our Board and authorized
at a meeting of our stockholders by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder. 

In addition, our restated certificate of incorporation does not provide for cumulative voting in the election of directors. Our Board is empowered to elect a
director to fill a vacancy created by the expansion of the Board or the resignation, death, or removal of a director in certain circumstances; and our advance notice provisions require that stockholders must comply with certain procedures in order
to nominate candidates to our Board or to propose matters to be acted upon at a stockholders’ meeting. 

 Our restated certificate of incorporation and amended and restated bylaws provide that all stockholder
actions are required to be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. Our restated certificate of incorporation also provides that,
subject to the terms of any one or more series or classes of preferred stock, any director or the entire Board may be removed from office at any time, but only for cause (as defined in the restated certificate of incorporation) and only by the
affirmative vote of the holders of at least a majority of the votes which all the stockholders would be entitled to cast in any annual election of directors, voting together as a single class. 

Our authorized but unissued Class A 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 Class A common stock and preferred 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. 
 Our restated
certificate of incorporation and amended and restated bylaws provide that, unless we consent in writing to an alternate forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive
