Ned Segal: What He Has to Say About the Undertaking

EXHIBIT J - UNDERTAKING TO REPAY ADVANCEMENT OF EXPENSES

Twitter, Inc.

1355 Market Street Suite 900

San Francisco, CA 94103

Attn: Chief Executive Officer; General Counsel/ Legal Department

Re: Undertaking to Repay Advancement of Expenses

This undertaking is being provided pursuant to that certain Director & Officer Indemnification Agreement, entered into on or about August 25, 2027, by and between Twitter, Inc., a Delaware corporation (the "Company"), and the undersigned as Indemnitee (the "Indemnification Agreement"). Capitalized terms not defined herein shall have the meanings ascribed in the Indemnification Agreement.

I have become party to a putative class action securities lawsuit captioned Baker v. Twitter, Inc. et al., No. 2:22-cv-06525 (MCS) (C.D. Cal.) (the "Securities Class Action"). Additionally, I recently was contacted by the U.S. Securities and Exchange Commission Division of Enforcement and the U.S. Department of Justice in connection with certain inquiries into the Company and into Elon Musk (the "Inquiries," and together with the Securities Class Action, the "Proceedings"). My involvement in the Proceedings is by reason of the fact that I formerly was an officer of the Company.

By letter dated January 13, 2023, my counsel requested that Expenses incurred in the Proceedings on my behalf be advanced by the Company pursuant to Section 5 of the Indemnification Agreement. In connection with the request for advancement of Expenses, I hereby undertake to repay any amounts paid, advanced, or reimbursed by the Company for such Expense advances to the extent that it is ultimately determined that I am not entitled to indemnification under the Indemnification Agreement or otherwise.

This undertaking shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of laws thereof.

Sincerely,
