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).

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 such Person (notwithstanding that such Person is not a party to this Agreement).

20.    Specific Performance. Each Party acknowledges and agrees that money damages would not be a sufficient remedy for any breach (or threatened breach) of this Agreement by it and that, in the event of any breach or threatened breach of this Agreement, (a) the Party seeking specific performance will be entitled to injunctive and other equitable relief, 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

-10-

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.

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.
