EX-10.10



 Exhibit 10.10 
 Twitter, Inc. 
 Change of Control Severance Policy 

(as effective upon adoption by the Compensation Committee) 
 This Change of Control Severance Policy (the “Policy”) is designed to provide certain protections to a select group of key Twitter, Inc. (“Twitter” or the
“Company”) employees if their employment is negatively affected by a change on control of Twitter. The Policy is designed to be an “employee welfare benefit plan,” as defined in Section 3(1) of the Employee Retirement
Income Security Act of 1974, as amended (“ERISA”) and this document is both the formal plan document and the required summary plan description for the Policy. 
 Eligible Employee: You are only eligible for Change of Control Severance Benefits under the policy if you are an eligible employee under this Policy (an “Eligible Employee”) and
comply with its terms. To be an Eligible Employee, on the date of a Change of Control of Twitter, you (1) must have been designated as eligible by the Compensation Committee of the Board (the “Compensation Committee”) and
(2) must have executed a Participation Agreement (as defined below). 
 Change of Control Severance Benefits: As an Eligible
Employee for Change of Control Severance Benefits, you will be eligible for severance benefits under this Policy if: (1) during the Change of Control Period (as defined below), (2) your employment with Twitter or any of its subsidiaries
terminates as a result of an Involuntary Termination (a “COC Qualified Termination”). If your employment with Twitter or any of its subsidiaries terminates as a result of a COC Qualified Termination, you will be eligible to receive
the applicable Equity Vesting, Cash Severance and COBRA Benefit described herein and specified on your Participation Agreement. All benefits under this Policy shall be subject to your compliance with the Release Requirement and timing modifications
required to avoid adverse taxation under Section 409A. 
 Equity Vesting: Upon a COC Qualified Termination, a
percentage set forth on your Participation Agreement of the then-unvested shares subject to each of your then-outstanding equity awards shall immediately vest and, in the case of options and stock appreciation rights, shall become exercisable (for
avoidance of doubt, no more than 100% of the shares subject to the outstanding portion of an equity award may vest and, with respect to an option or stock appreciation right, become exercisable pursuant to this provision). In the case of equity
awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at target levels as to the percentage set forth on your Participation Agreement. Subject to any payment delay necessary to comply with
Section 409A (as defined below), any restricted stock units, performance shares, performance units, and/or similar full value awards that vest under this paragraph will be settled on the
61st day following your COC Qualified Termination.

 Cash Severance: Upon a COC Qualified Termination, you will be eligible to receive a lump-sum severance payment
equal to a percentage set forth on your Participation Agreement of your Base Salary. Your severance payment will be paid in cash and in full on the 61st day following your COC Qualified Termination. If you die before all amounts have been paid, such unpaid amounts will
be paid to your designated beneficiary, if living, or otherwise to your personal representative in a lump-sum payment (less any withholding taxes) as soon as possible following your death. 
 COBRA Benefit: Upon a COC Qualified Termination, if you make a valid election under COBRA to continue your health coverage, the Company will (for a limited time set forth on your Participation
Agreement) pay the cost of such continuation coverage for you and any eligible dependents that were covered under the Company’s health care plans immediately prior to the date of your eligible termination








 
(“COBRA Benefit”). Notwithstanding the preceding, if the Company determines in its sole discretion that it cannot provide the COBRA Benefit without potentially violating
applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will instead provide you a taxable lump-sum payment in an amount equal to the applicable number of months of the COBRA Benefit
multiplied by the monthly COBRA premium that you would be required to pay to continue your group health coverage in effect on the date of termination of employment (which amount will be based on the premium for the first month of COBRA
coverage). If the Company provides for a taxable cash payment in lieu of the COBRA Benefit, then such cash payment will be made regardless of whether you elect COBRA continuation coverage and such payment will be made in full on the 61st day following your termination of employment. 

Release: Notwithstanding any other term of this Policy, the receipt of any severance payments or benefits pursuant to this Policy is subject to
your signing and not revoking the Company’s then-standard separation agreement and release of claims (the “Release” and such requirement, the “Release Requirement”), which must become effective and irrevocable
no later than the sixtieth (60th) day following your COC Qualified Termination (the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, you will forfeit any right to severance
payments or benefits under this Policy. In no event will severance payments or benefits be paid or provided until the Policy until the Release actually becomes effective and irrevocable. 
 For purposes of this Policy, the following terms shall have the following meanings: 

“Base Salary” means your annual base salary as in effect immediately prior to your COC Qualified Termination date or, if greater, at the
level in effect immediately prior to the Change of Control. 
 “Board” means the Board of Directors of the Company. 

“Cause” means (a) your unauthorized use or disclosure of the Company’s confidential information or trade secrets, which use or
disclosure causes material harm to the Company; (b) your breach of any agreement between you and the Company; (c) your failure to comply with the Company’s written policies or rules, including its code of conduct; (d) your
conviction of, or plea of “guilty” or “no contest” to, a felony under the laws of the United States or any state thereof; (e) your gross negligence or willful misconduct in the performance of your duties; (f) your
continuing failure to perform assigned duties after receiving written notification of the failure from the Board (or for Eligible Employees other than the Chief Executive Officer, from the Chief Executive Officer); or (g) your failure to
cooperate in good faith with a governmental or internal investigation of the Company or its directors, officers or employees, if the Company has requested your cooperation; provided, however, that “Cause” will not be deemed to exist
in the event of subsections (b), (c) or (f) above unless you have been provided with (i) 30 days’ written notice by the Board or the act or omission constituting “Cause” and (ii) 30 days’ opportunity to cure
such act or omission, if capable of cure. 
 “Change of Control” means the occurrence of any of the following events:

 A. Change in Ownership of the Company. A change in the ownership of the Company which occurs on the date that any
one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting
power of the stock of the Company; provided, however, that the acquisition of additional stock by any one Person who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered
a Change of Control; or 







 B. Change in Effective Control of the Company. If the Company has a class of
securities registered pursuant to Section 12 of the Exchange Act, a change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any 12 month period by directors whose
appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause (B), if any Person is considered to be in effective control of the Company, the
acquisition of additional control of the Company by the same Person will not be considered a Change of Control; or 

C. Change in Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a substantial portion
of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the 12 month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross
fair market value equal to or more than 50% of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection, the following will
not constitute a change in the ownership of a substantial portion of the Company’s assets: (i) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (ii) a transfer of assets
by the Company to: (a) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (b) an entity, fifty percent (50%) or more of the total value or voting power of
which is owned, directly or indirectly, by the Company, (c) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (d) an entity, at
least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person. 

Notwithstanding the foregoing, a transaction will not be deemed a Change of Control unless the transaction qualifies as a change in
control event within the meaning of Section 409A (as defined below). 
 “Change of Control Period” means the period on,
and twelve (12) months following, a Change of Control. 
 “COBRA” means the Consolidated Omnibus Budget Reconciliation Act
of 1985, as amended. 
 “Disability” means the total and permanent disability as defined in Section 22(e)(3) of the Code
unless the Company maintains a long-term disability plan at the time of the Eligible Employee’s termination, in which case, the determination of disability under such plan also will be considered “Disability” for purposes of this
Policy. 
 “Exchange Act” means the Securities and Exchange Act of 1934, as amended. 

“Involuntary Termination” means a termination of employment by the Company other than for Cause, death or Disability. 

“Participation Agreement” means an agreement in the form attached hereto as Exhibit A. 

Section 409A: The Company intends that all payments and benefits provided under this Policy or otherwise are exempt from, or comply with, the
requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and any guidance promulgated thereunder (“Section 409A”) so that none of the payments or benefits will be subject to the additional tax imposed
under Section 409A, and any ambiguities herein will be interpreted to so comply. No payment or benefits to be paid to you, if any, pursuant to this Policy or otherwise, when considered together with any other severance payments or separation
benefits that are considered deferred compensation under Section 409A (together, the “Deferred Payments”) will be paid or otherwise provided until you have a “separation from service”








 
within the meaning of Section 409A. If, at the time of your termination of employment, you are a “specified employee” within the meaning of Section 409A and the payment of the
Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally means that you will receive payment on the first payroll date that occurs on or after the date
that is 6 months and 1 day following your termination of employment. The Company reserves the right to amend the Policy as it deems necessary or advisable, in its sole discretion and without the consent of any Eligible Employee or any other
individual, to comply with Section 409A the Code or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any additional tax. Each payment, installment and benefit payable
under this Policy is intended to constitute a separate payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). 
 In no
event will the Company reimburse you for any taxes that may be imposed on you as a result of Section 409A. Each payment and benefit payable hereunder is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of
the Treasury Regulations. 
 Parachute Payments: 
 Reduction of Severance Benefits. Notwithstanding anything set forth herein to the contrary, if any payment or benefit that an Eligible Employee would receive from the Company or any other party
whether in connection with the provisions herein or otherwise (the “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the
“Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Best Results Amount. The “Best
Results Amount” shall be either (x) the full amount of such Payment or (y) such lesser amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account
the applicable federal, state and local employment taxes, income taxes and the Excise Tax, results in the Eligible Employee’s receipt, on an after-tax basis, of the greater amount notwithstanding that all or some portion of the Payment may be
subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Best Results Amount, reduction shall occur in the following order: reduction of cash payments;
cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the
date of grant of the Eligible Employee’s stock awards unless the Eligible Employee elects in writing a different order for cancellation. The Eligible Employee shall be solely responsible for the payment of all personal tax liability that is
incurred as a result of the payments and benefits received under this Policy, and the Eligible Employee will not be reimbursed by the Company for any such payments. 
 Determination of Excise Tax Liability. The Company shall select a professional services firm to make all of the determinations required to be made under these paragraphs relating to “Parachute
Payments.” The Company shall request that firm provide detailed supporting calculations both to the Company and the Eligible Employee prior to the date on which the event that triggers the Payment occurs if administratively feasible, or
subsequent to such date if events occur that result in parachute payments to the Eligible Employee at that time. For purposes of making the calculations required under these paragraphs relating to “Parachute Payments,” the firm may make
reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith determinations concerning the application of the Code. The Company and the Eligible Employee shall furnish to the firm such information and
documents as the firm may reasonably request in order to make a determination under these paragraphs relating to “Parachute 







 
Payments.” The Company shall bear all costs the firm may reasonably incur in connection with any calculations contemplated by these paragraphs relating to “Parachute Payments.” Any
such determination by the firm shall be binding upon the Company and the Eligible Employee, and the Company shall have no liability to the Eligible Employee for the determinations of the firm. 

Administration: The Policy will be administered by the Compensation Committee or its delegate (in each case, an “Administrator”).
The Administrator will have full discretion to administer and interpret the Policy. Any decision made or other action taken by the Administrator with respect to the Policy, and any interpretation by the Administrator of any term or condition of the
Policy, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. The Administrator is the “named fiduciary” of the Policy for purposes of ERISA and will be subject
to the fiduciary standards of ERISA when acting in such capacity. 
 Attorneys Fees: The Company and each Eligible Employee bear their
own attorneys’ fees incurred in connection with any disputes between them. 
 Exclusive Benefits: Except as may be set forth in your
Participation Agreement, this Policy is intended to be the only agreement between you and the Company regarding any severance payments or benefits to be paid to you on account of a termination of employment whether unrelated to, concurrent with, or
following, a Change of Control. Accordingly, by executing your Participation Agreement, you hereby forfeit and waive any rights to any severance or change of control benefits set forth in any employment agreement, offer letter and/or equity award
agreement, except as set forth in this Policy and/or in your Participation Agreement. 
 Withholding: The Company is authorized to
withhold from any payments or benefits all federal, state, local and/or foreign taxes required to be withheld therefrom and any other required payroll deductions. 
 Amendment or Termination: The Company reserves the right to amend or terminate the Policy at any time, without advance notice to any Eligible Employee or other individual and without regard to the
effect of the amendment or termination on any Eligible Employee or on any other individual. Notwithstanding the preceding, (a) any amendment to the Policy that causes an individual or group of individuals to cease to be an Eligible Employee
will not be effective unless it is both approved by the Administrator and communicated to the affected individual(s) in writing at least 6 months prior to the effective date of the amendment or termination, and (b) no amendment or termination
of the Policy shall be made within 12 months following a Change of Control to the extent that such amendment or reduction would reduce the benefits provided hereunder or impair an Eligible Employee’s eligibility under the Policy (unless the
affected Eligible Employee consents to such amendment or termination). Any amendment or termination of the Policy will be in writing. Any action of the Company in amending or terminating the Policy will be taken in a non-fiduciary capacity.

 Claims Procedure: Any Eligible Employee who believes he or she is entitled to any payment under the Policy may submit a claim in
writing to the Administrator. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The
notice will also describe any additional information needed to support the claim and the Policy’s procedures for appealing the denial. The denial notice will be provided within 90 days after the claim is received. If special circumstances
require an extension of time (up to 90 days), written notice of the extension will be given within the initial 90-day period. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which
the Administrator expects to render its decision on the claim. 







 Appeal Procedure: If the claimant’s claim is denied, the claimant (or his or her authorized
representative) may apply in writing to the Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial or else the claimant
loses the right to review. The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues and comments in writing. The
Administrator will provide written notice of the decision on review within 60 days after it receives a review request. If additional time (up to 60 days) is needed to review the request, the claimant (or representative) will be given
written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision. If the claim is denied (in full or
in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The notice shall also include a statement that the claimant will be
provided, upon request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to bring an action under Section 502(a) of ERISA.

 Successors: Any successor to the Company of all or substantially all of the Company’s business and/or assets (whether direct or
indirect and whether by purchase, merger, consolidation, liquidation or other transaction) will assume the obligations under the Policy and agree expressly to perform the obligations under the Policy the same manner and to the same extent as the
Company would be required to perform such obligations in the absence of a succession. For all purposes under the Policy, the term “Company” will include any successor to the Company’s business and/or assets which become bound by the
terms of the Policy by operation of law, or otherwise. 
 Applicable Law: The provisions of the Policy will be construed, administered
and enforced in accordance with ERISA and, to the extent applicable, the internal substantive laws of the state of California (but not its conflict of laws provisions).

 Statement of ERISA Rights. 
 Policy Eligible Employees have certain rights and protections under ERISA: 
 They
may examine (without charge) all Policy documents, including any amendments and copies of all documents filed with the U.S. Department of Labor, such as the Policy’s annual report (Internal Revenue Service Form 5500). These documents are
available for review in the Company’s Human Resources Department. 
 They may obtain copies of all Policy documents and
other Policy information upon written request to the Plan Administrator. A reasonable charge may be made for such copies. 
 In
addition to creating rights for Eligible Employees, ERISA imposes duties upon the people who are responsible for the operation of the Policy. The people who operate the Policy (called “fiduciaries”) have a duty to do so prudently and in
the interests of Eligible Employees. No one, including the Company or any other person, may fire or otherwise discriminate against an Eligible Employee in any way to prevent them from obtaining a benefit under the Policy or exercising rights under
ERISA. If an Eligible Employee’s claim for a severance benefit is denied, in whole or in part, they must receive a written explanation of the reason for the denial. An Eligible Employee has the right to have the denial of their claim reviewed.
(The claim review procedure is explained above.) 
 Under ERISA, there are steps Eligible Employees can take to enforce the above
rights. For instance, if an Eligible Employee requests materials and does not receive them within 30 days, they may file suit in a federal court. In such a case, the court may require the Administrator to provide the materials and to pay the
Eligible Employee up to $110 a day until they receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If an Eligible Employee has a claim which is denied or ignored, in whole or in
part, he or she may file suit in a state or federal court. If it should happen that an Eligible Employee is discriminated against for asserting their rights, he or she may seek assistance from the U.S. Department of Labor, or may file suit in a
federal court. 
 In any case, the court will decide who will pay court costs and legal fees. If the Eligible Employee is
successful, the court may order the person sued to pay these costs and fees. If the Eligible Employee loses, the court may order the Eligible Employee to pay these costs and fees, for example, if it finds that the claim is frivolous. 

If an Eligible Employee has any questions regarding the Policy, please contact the Plan Administrator. If an Eligible Employee has any
questions about this statement or about their rights under ERISA, they may contact the nearest area office of the Employee Benefits Security Administration (formerly the Pension and Welfare Benefits Administration), U.S. Department of Labor, listed
in the telephone directory, or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W. Washington, D.C. 20210. An Eligible Employee may also obtain
certain publications about their rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.
