We appreciate your services as interim Chief Financial Officer since July 22, 2016 and we are now pleased to offer you the permanent Chief Financial Officer role, effective as of November 7, 2016.

This is your Employment Letter (the “Letter”) with CA, Inc., a Delaware corporation (the “Company”). It sets forth the terms of your employment with the Company and your service to the Company and its affiliates from time to time (together, the “Group”).

(a)     Position. You will be employed in the position of Executive Vice President, Chief Financial Officer of the Company.

(b)     Authority, Responsibilities and Reporting. You will report directly to the Company’s Chief Executive Officer. Your duties, responsibilities and authority shall be such duties, responsibilities and authority as are consistent with the above job titles and such other duties, responsibilities and authority as the Chief Executive Officer shall from time to time specify commensurate with your position. During your employment, your principal place of performance of your responsibilities under this Letter will be New York, NY.

(c)     Performance. During your employment, you will (a) serve the Group faithfully, diligently and to the best of the your ability under the direction of the Chief Executive Officer, (b) devote your full working time and best efforts, attention and energy to the performance of your duties to the Group and (c) not do anything inconsistent with your duties to the Group.

(d)     Other Activities. During your employment, you will not render any business, commercial or professional services to any non-member of the Group. However, you may (1) serve on corporate, civic or charitable boards, (2) manage personal

investments, or (3) deliver lectures, or fulfill speaking engagements or teach at educational institutions, so long as (A) these activities do not interfere with your performance of your responsibilities under this Letter and (B) any service on a corporate, civic, charitable board or any other outside organization must be approved by the Company in advance and in writing in accordance with the Company’s written policies as in effect from time to time.

(a)     Your new role under this Letter will begin on November 7, 2016 (the “Start Date” of this Letter) and will continue until your employment is terminated by you or by the Company (this period referred to as the “Employment Period”). References in this Letter to “your employment” are to your employment under this Letter.

(b)     You and the Company agree that your employment with the Company is “at-will” which means that either you or the Company may terminate your employment at any time, for any reason whatsoever, with or without Cause or Good Reason (as such terms are defined herein), in accordance with the terms of this Letter.

(a)     Salary. For the portion of the Company’s fiscal year 2017 (beginning on April 1, 2016 and ending on March 31, 2017) following your Start Date, you will receive an annual base salary at the rate of $550,000. After fiscal year 2017 your annual base salary will be determined by the Compensation and Human Resources Committee of the Board of Directors (the “Compensation Committee”) in its sole discretion and in accordance with its normal review process; provided that your annual base salary will not be reduced below $550,000 (other than in connection with a reduction proportionately applied to the annual base salaries of the Company’s other executive officers or in connection with a broad-based salary reduction program). Your annual base salary as in effect from time to time is referred to as your “Salary”. Your Salary will be paid in accordance with the Company’s normal practices for senior executives but you shall in any event receive pro-rata installments of your Salary at least once each calendar month.

(b)     Annual Performance Cash Incentive. For fiscal year 2017, you will be eligible to receive an annual performance cash incentive (your “Annual Performance Cash Incentive”) in accordance with the Company’s 2011 Incentive Plan (and any successor plan). The target level for your fiscal year 2017 Annual Performance Cash Incentive will be $550,000, pro-rated based on the number of days between the Start Date and the end of fiscal year 2017. The terms of the Annual Performance Cash Incentive, including the performance metrics used in determining your Annual Performance Cash Incentive, will be subject to the determination and approval of the Compensation Committee on an annual

basis. For each fiscal year after fiscal year 2017, your Annual Performance Cash Incentive target level will be subject to the review and approval of the Compensation Committee.

(c)     Long-Term Incentive Awards. Beginning with the Company’s 2017 fiscal year, you will annually be eligible to receive long-term incentive awards (“Long-Term Incentive Awards”) as determined by the Company in accordance with the Company’s 2011 Incentive Plan (and any successor plan). The target award level for your Long-Term Incentive Awards under the Company’s Long-Term Incentive Plan for fiscal year 2017 will be $1,500,000, pro-rated based on the number of days between the Start Date and the end of fiscal year 2017, and will be granted effective November 15, 2016 and pursuant to the Company’s methodologies and consistent with how such awards are granted to other executive officers for fiscal year 2017. For fiscal year 2017, your pro-rated target for the Long-Term Incentive Awards will be offset by the fiscal year 2017 long-term incentive target award already communicated to you in connection with your role with the Company prior to the Start Date. The terms of the Long-Term Incentive Awards, including the performance metrics used in determining your Long-Term Incentive Awards payouts, will be subject to the determination and approval of the Compensation Committee on an annual basis and all pro-rations and adjustments will be made consistent with the Company’s methodologies. For each fiscal year after fiscal year 2017, your Long-Term Incentive Award target level will be subject to the review and approval of the Compensation Committee.

(d)     Prior awards. For the portion of Fiscal Year 2017 prior to the Start Date, your outstanding annual performance cash incentive will be pro-rated and subject to the terms applicable to the corporate Senior Vice President awards (as approved by the Compensation Committee in May 2016), with any payouts or grants to be made at the same time as for other Senior Vice Presidents and based on the attainment of the applicable performance goals.

All other outstanding cash or equity awards (including any sign-on or retention awards) will continue to be governed by their terms, including any applicable plans and award agreements. For the avoidance of doubt, the provisions relating to the Cash Payments and Equity Grant, as set forth in your Retention Letter with the Company, dated July 22, 2017 (the “Retention Letter”), shall remain in effect and are incorporated herein by reference.

(a)     Vacation. You will be entitled to paid annual vacation consistent with the Company’s vacation policy as in effect from time to time.

(b)     Employee Benefit Plans. During your employment, you will be eligible to participate in the Company’s employee benefit and welfare plans, including plans providing retirement benefits, deferred compensation, medical, dental, hospitalization, life or disability insurance and the Savings Harvest 401(k) Plan on a basis that is no less favorable than what is provided to other senior executives of the Company generally.

(c)     Change in Control Severance Policy. The Compensation Committee has approved your participation in the Company’s Change in Control Severance Policy (as may be amended from time to time, the “CIC Severance Policy”) as a Schedule A participant (i.e., at 2.99 multiple) in accordance with the terms of such CIC Severance Policy. Your participation and any other terms and conditions related to participation shall be at the discretion of the Compensation Committee or the Board of Directors in accordance with the terms of the CIC Severance Policy.

(a)     No Reason Required. Subject to Section 6, you or the Company may terminate your employment at any time for any reason, or for no reason.

(b)     Advance Notice Generally Required. Notwithstanding anything else contained in this Letter to the contrary, subject to Section 6 of this Letter and the terms of the CA, Inc. Executive Severance Policy, as may be amended from time to time (the “Executive Severance Policy”), the Company and you each acknowledge and agree that your employment with the Company may be terminated by either the Company upon 30 days’ written notice to you (except in the case of a termination for Cause, as defined in the Executive Severance Policy, in which case notice will not be required) or by you upon 90 days’ written notice to the Company in the event of a resignation without Good Reason, as defined in the Executive Severance Policy. Notwithstanding the foregoing, in the event of a Qualifying Termination as described in Section 6 below, the notice provisions set forth in the Executive Severance Policy will apply. In addition, this Letter shall automatically terminate upon your death or disability (as determined in accordance with the Company’s long-term disability program and policies). The Company may determine to waive all or part of your 90-day notice period at its discretion (but shall provide you with full compensation and benefits for the portion of such period that occurs prior to your Termination Date, provided that your Salary shall continue for no less than 30 days during such period). Upon termination of your employment for any reason whatsoever, the Company shall have no further obligations to you after your Termination Date other than those set forth in Section 6 of this Letter. The effective date of your termination of employment shall be referred to herein as the “Termination Date.”

(a)     General Effect. On termination of employment in accordance with Section 5, your employment will end and the Group will have no further obligations to you except as provided in this Section 6.

(b)     By the Company Without Cause or By You With Good Reason. If, during your Employment Period, the Company terminates your employment without “Cause” or you terminate your employment for “Good Reason” (i.e., experience a “Qualifying Termination”, as each of these terms are defined in the Executive Severance Policy)):

(1)     The Company will pay you the following as of the end of your employment: (i) your unpaid Salary (which shall be paid to you on the date of the Company’s first regularly scheduled payroll after your Termination Date), (ii) any accrued but unpaid business expense reimbursement, (iii) any unpaid but awarded Annual Performance Cash Incentive for the fiscal year preceding the fiscal year in which the Termination Date occurs and (iv) any vested benefits and other amounts that you are otherwise entitled to receive under any employee benefit plan, policy, practice or program of the Company or any of its affiliates (which shall be payable in accordance with such employee benefit plan, policy, practice or program, as the case may be) (collectively, the “Accrued Benefits”);

(2)     You will be eligible for the termination benefits in accordance with, and subject to the terms and conditions of, the Executive Severance Policy and, if applicable, the CIC Severance Policy;

(3)     Any unpaid installments of the Cash Payments (as provided in the Retention Letter) will be paid on the scheduled dates set forth in the Retention Letter; and

(4)     All other outstanding awards will be governed by the terms of the applicable plans and award agreements.

You shall not be entitled to receive any other payments or benefits in the nature of severance or termination pay, except as otherwise provided herein.

(c)     Condition. The Company will not be required to make the payments and provide the benefits stated in this Section 6 (other than your Accrued Benefits), unless you execute and deliver to the Company, and do not revoke, a valid and effective release and waiver in accordance with the Executive Severance Policy and/or CIC Severance Policy, as applicable.

(a)     Employment and Confidentiality Agreement. You have already executed the Company Employment and Confidentiality Agreement the terms of which are incorporated herein by reference. Pursuant to the Employment and Confidentiality Agreement, you will be subject to certain covenant provisions including non-solicitation of customers and employees provisions for one-year following the termination of your employment for any reason. The Company may waive this provision in its discretion.

(b)     No Public Statement or Disparagement. You agree that you will not make any public statement that would libel, slander or disparage (the foregoing, to “Disparage”) any member of the Group or any of their respective past or present officers, directors, employees or agents, and the Company agrees that the members of the Board of Directors and the Company’s executive officers will not Disparage you; provided that nothing in this Section 7 or in any other provision of this Letter shall prevent either you, the Company or the Company’s executive officers or Board members, respectively, from providing truthful and candid assessments of Group personnel and processes in accordance with established procedures or truthful testimony or other information in any legal proceeding, investigation or as otherwise may be required by law.

This Letter may only be modified, in writing, jointly by you and a duly authorized representative of the Company.

The parties agree to renegotiate in good faith the terms of this Letter at no additional cost to the Company (other than the Company’s routine expenses for outside counsel), if you and the Company determine that this Letter as structured would have adverse tax consequences to

you under applicable law. To extent that you would otherwise be entitled to any payment under this Letter or any plan or arrangement of the Company or its affiliates, that constitutes “deferred compensation” subject to Section 409A and that if paid during the six months beginning on the Termination Date would be subject to the Section 409A additional tax because you are a “specified employee” (within the meaning of Section 409A and as determined by the Company), the payment will be paid to you on the earlier of the six-month anniversary of the Termination Date, a change in ownership or effective control of the Company (within the meaning of Section 409A and to the extent permitted by Section 409A) or your death. Similarly, to the extent that you would otherwise be entitled to any benefit (other than a payment) during the six months beginning on the Termination Date that would be subject to the Section 409A additional tax, the benefit will be delayed and will begin being provided on the earlier of the six-month anniversary of the Termination Date, a change in ownership or effective control of the Company (within the meaning of Section 409A and to the extent permitted by Section 409A) or your death. In addition, any payment or benefit due upon a termination of employment that represents a “deferral of compensation” within the meaning of Section 409A shall be paid or provided to you only upon a “separation from service” as defined in Treas. Reg. 1.409A-1(h). To the extent applicable, each severance payment made under this Letter shall be deemed to be separate payments, amounts payable under Section 6 of this Letter shall be deemed not to be a “deferral of compensation” subject to Section 409A to the extent provided in the exceptions in Treas. Reg. 1.409A-1(b)(4) (“short-term deferrals”) and (b)(9) (“separation pay plans,” including the exception under subparagraph (iii)) and other applicable provisions of Treas. Reg. 1.409A-1 through 1.409A-6.

Notwithstanding anything to the contrary in this Letter or elsewhere, any payment or benefit under this Letter or otherwise that is exempt from Section 409A pursuant to Treas. Reg. 1.409A-1(b)(9)(v)(A) or (C) shall be paid or provided to you only to the extent that the expenses are not incurred, or the benefits are not provided, beyond the last day of the second taxable year following the taxable year in which the “separation from service” occurs; and provided further, that such expenses shall be reimbursed no later than the last day of the third taxable year following the taxable year in which your “separation from service” occurs.  Except as otherwise expressly provided herein, to the extent any expense reimbursement or the provision of any in-kind benefit under this Letter is determined to be subject to Section 409A, the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement in any other calendar year (except for any lifetime or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year following the calendar year in which you incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit.

Very truly yours,
