 Exhibit 10.9.10 

PERFORMANCE-BASED RESTRICTED SHARE UNIT AGREEMENT 
 Under the Teradata 2012 Stock Incentive Plan 
 You have been awarded the contingent right
to receive a credit of share units (the “Share Units”) under the Teradata 2012 Stock Incentive Plan (the “Plan”), upon the terms and subject to the conditions of this Performance-Based Restricted Share Unit Agreement (this
“Agreement”) and the Plan. Please refer to the share unit information page on the website of Teradata’s third party Plan administrator for your “Target Number of Share Units.” Capitalized terms used but not otherwise defined
herein shall have the meanings ascribed to such terms in the Plan. 
 1. Crediting of Share Units. 

(a) In General. Your right to receive a credit of all, a portion, or a multiple of the Target Number of Share Units shall be
contingent upon the extent to which Teradata Corporation (the “Company”) achieves the performance goals set forth on the attached Exhibit A (the “Performance Goals”) for the performance period commencing
                    ,              and ending
                    ,              (the “Performance Period”), in accordance
with the payout levels set forth on the attached Exhibit A (the “Performance Metrics”). The Compensation and Human Resource Committee of the Company’s Board of Directors (the “Committee”) may establish special
adjustments that will be applied in calculating the extent to which the Performance Goals have been satisfied, provided that the adjustments are set forth in writing no later than 90 days after the beginning of the Performance Period. 

(b) Crediting to Account. After the end of the Performance Period, the Committee shall determine in writing the extent, if any, to
which each of the Performance Goals has been satisfied and shall determine the percentage, if any, of the Target Number of Share Units that shall be credited to a book entry account established on your behalf (the “Account”), based on the
payout level identified in the Performance Metrics. Each Share Unit credited to your Account under this Section 1(b) shall represent the contingent right to receive one Share and shall at all times be equal in value to one Share. 

(i) If, upon the conclusion of the Performance Period, the Company achieves less than 25% of the target level of a Performance Goal,
then you shall not receive a credit of any Share Units with respect to that Performance Goal, and if the Company achieves less than 25% of the target level for both Performance Goals, this Agreement shall terminate immediately without further action
or notice. 
 (ii) If, upon the conclusion of the Performance Period, the Company achieves 25% or more of the target level of a
Performance Goal, then you shall be credited with a number of Share Units with respect to such Performance Goal, effective on the day in which the Committee certifies the achievement of the Performance Goal as provided in this Section 1(b) (the
“Crediting Date”), equal to the product of (A) your Target Number of Share Units, multiplied by (B) the combined weighted average of the payout levels for both Performance Goals as identified in the Performance Metrics (subject
to such rounding conventions as may be implemented from time-to-time by Teradata’s third party Plan administrator). 

 (c) Forfeiture of Share Units. Except as otherwise provided in Section 3, your
right to receive a credit of Share Units shall be forfeited automatically without further action or notice in the event that you cease to be employed by the Company or any of its affiliate companies (referred to collectively herein as
“Teradata”) through the end of the Performance Period. 
 2. Vesting, Forfeiture and Payment of Share Units.

 (a) Vesting. The Share Units, if any, credited to your Account in accordance with Section 1 above shall be
subject to the following vesting schedule: 
 (i) One-third of the Share Units shall vest on each of the following dates
(subject to such rounding conventions as may be implemented from time to time by Teradata’s third party Plan administrator): (A) the Crediting Date, (B) the first anniversary of the Crediting Date, and (C) the second anniversary
of the Crediting Date (each a “Vesting Date”), provided that you are continuously employed by Teradata until the applicable Vesting Date. 
 (ii) If you cease to be employed by Teradata due to (A) your death, or (B) your Disability (defined by reference to Teradata’s long-term disability plan that covers you), in either case
after the end of the Performance Period but prior to a Vesting Date, then the Share Units shall become fully vested upon such termination. 
 (iii) If you cease to be employed by Teradata prior to a Change in Control due to (A) your Retirement (defined as termination by you of your employment with Teradata at or after age 55 with the
consent of the Committee); or (B) a reduction-in-force, in either case after the end of the Performance Period but prior to a Vesting Date, then a portion of the Share Units credited to your Account that have not yet vested shall become fully
vested upon such termination, determined by multiplying (I) the number of unvested Share Units credited to your Account on the date of termination that would have vested on the next Vesting Date had you remained employed with Teradata through
such date, by (II) a fraction, the numerator of which is the number of full and partial months of employment you completed commencing with the Vesting Date that occurred immediately prior to your termination, and the denominator of which is 12
months (with the resulting product rounded to the nearest whole number); provided that if your termination occurs during the period commencing immediately after the end of the Performance Period but prior to the Crediting Date, the fraction
described above shall be deemed to be 12/12. The remaining number of Share Units shall be forfeited without further action or notice. 
 (iv) If a Change in Control occurs after the end of the Performance Period and prior to a Vesting Date, and the Share Units are not assumed, converted or replaced by the continuing entity, then the Share
Units shall vest upon the Change in Control. 
 (v) If a Change in Control occurs after the end of the Performance Period and
prior to a Vesting Date, and the Share Units are assumed, converted or replaced by the continuing entity, then the Share Units shall continue to vest in accordance with Section 2(a)(i); provided, however, that if you cease to be employed by
Teradata due to (A) termination of your employment by Teradata without Cause, (B) termination of your employment with 

 
Teradata on account of death, Disability, Retirement, or a reduction-in-force, or (C) if you are a participant in the Teradata Change in Control Severance Plan, a Teradata Severance Policy
or a similar arrangement that defines “Good Reason” in the context of a resignation following a Change in Control (a “CIC Plan”), termination of your employment with Teradata for “Good Reason” as defined in the CIC Plan
within the two-year period commencing on the Change in Control, then the Share Units credited to your Account that have not yet vested shall vest in full upon such termination. 

(b) Forfeiture. The Share Units credited to your Account that have not yet vested pursuant to Section 2(a) shall be forfeited
automatically without further action or notice if you cease to be employed by Teradata prior to a Vesting Date other than as provided in Sections 2(a)(ii), (iii) or (v). 
 (c) Payment. Except as otherwise provided in Section 3 or Section 4 of this Agreement, the Company shall deliver the Shares underlying the vested Share Units credited to your Account in
accordance with this Agreement within seventy (70) days after the earlier of (i) the applicable Vesting Date(s), or (ii) your termination of employment. 
 3. Certain Events During Performance Period. 
 (a) Certain
Terminations. If during the Performance Period you cease to be employed by Teradata prior to a Change in Control due to death, Disability, Retirement or a reduction-in-force, then the Company shall credit to your Account a pro-rated number of
Share Units, which shall be fully vested, and which shall be calculated by multiplying (i) the actual number of Share Units that would have been credited to your Account in accordance with Section 1 of this Agreement had you continued in
employment throughout the Performance Period, determined based on the actual performance of the Company during such Performance Period, by (ii) a fraction, the numerator of which is the number of full and partial months of employment you
completed commencing with January 1, 2012, and the denominator of which is 36 months (subject to such rounding conventions as may be implemented from time-to-time by Teradata’s third party Plan administrator). Except as otherwise provided
in Section 4 of this Agreement, the Company shall deliver to you the Shares underlying the pro-rated number of Share Units within seventy (70) days after the end of the Performance Period. 

(b) Change in Control. 
 (i) If a Change in Control occurs during the Performance Period, and this award is not assumed, converted or replaced by the continuing entity, then the Target Number of Share Units shall be credited to
your Account, as of the date of the Change in Control, and the units shall be fully vested at that time. The Company shall deliver to you the Shares underlying the Target Number of Share Units within 30 days after such Change in Control.
Notwithstanding the foregoing, to the extent that your right to receive such Shares constitutes a “deferral of compensation” within the meaning of Section 409A of the Code (“Section 409A”), the Company shall deliver to you
the Shares underlying the Target Number of Share Units within seventy (70) days after the earlier of (i) the end of the Performance Period, or (ii) your termination of employment (except as otherwise provided in Section 4 of this
Agreement). 

 (ii) If a Change in Control occurs during the Performance Period, and this award is
assumed, converted or replaced by the continuing entity, then the Target Number of Share Units shall be credited to your Account, as of the date of the Change in Control, and the Share Units shall continue to vest in accordance with
Section 2(a)(i); provided, however, that if you cease to be employed by Teradata due to (A) termination of your employment by Teradata without Cause, (B) termination of your employment with Teradata on account of death, Disability,
Retirement, or a reduction-in-force, or (C) if you are a participant in a CIC Plan, termination of your employment with Teradata for “Good Reason” as defined in the CIC Plan within the two-year period commencing on the Change in
Control, then the Share Units credited to your Account that have not yet vested shall vest in full upon such termination. If the Target Number of Share Units credited to your Account in accordance with this Section 3(b)(ii) becomes vested by
reason of a termination of your employment that occurs on or prior to the end of the Performance Period, then, except as otherwise provided in Section 4 of this Agreement, the Company shall deliver to you the Shares underlying the Target Number
of Share Units within seventy (70) days after the end of the Performance Period. If the Target Number of Share Units credited to your Account in accordance with this Section 3(b)(ii) becomes vested after the end of the Performance Period,
then except as otherwise provided in Section 4 of this Agreement, the Company shall deliver the Shares underlying the vested Target Number of Share Units credited to your Account within seventy (70) days after the earlier of (x) the
applicable Vesting Date(s), or (y) your termination of employment. 
 4. Section 409A Compliance. The intent of
the parties is that payments under this Agreement comply with Section 409A of the Code or are exempt therefrom and this Agreement shall be interpreted, administered and governed in accordance with such intent. 

(a) Termination of Employment. To the extent that you are a U.S. taxpayer, a termination of employment shall not be deemed to have
occurred for purposes of any provision of this Agreement providing for the payment of Shares subject to Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the
meaning of Section 409A and you are no longer providing services (at a level that would preclude the occurrence of a “separation from service” within the meaning of Section 409A) to Teradata as an employee or consultant, and for
purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service” within the meaning of Section 409A. 

(b) Payment Delay for Specified Employees. If you are a “specified employee,” as determined under the Company’s
policy for identifying specified employees on the date of termination, then to the extent required in order to comply with Section 409A, all payments made under this Agreement that constitute a “deferral of compensation” within the
meaning of Section 409A that are provided as a result of a “separation from service” within the meaning of Section 409A for any reason other than your death and that would otherwise be paid or provided during the first six months
following such separation from service shall be accumulated through and paid within 30 days after the first business day that is more than six months after the date of your separation from service (or, if you die during such six-month period, within
30 days after your death). 

 (c) Acceleration of Payment. Notwithstanding anything to the contrary contained in
this Agreement, the Committee shall have the right, at any time in its sole discretion, to accelerate the time of a payment under this Agreement to a time otherwise permitted under Section 409A in accordance with the requirements, restrictions
and limitations of Treasury Regulation Section 1.409A-3(j). 
 5. Confidentiality. By accepting this award, unless
disclosure is required or permitted by applicable law or regulation, you agree to keep this Agreement confidential and not to disclose its contents to anyone except your attorney, your immediate family, or your financial consultant, provided such
persons agree in advance to keep such information confidential and not disclose it to others. The Share Units will be forfeited if you violate the terms and conditions of this Section 5. 

6. Transferability. At all times before payment, the Share Units may not be sold, transferred, pledged, assigned or otherwise
alienated, except by beneficiary designation, will or by the laws of descent and distribution upon your death. Any purported transfer or encumbrance in violation of the provisions of this Section 6 shall be void, and the other party to any such
purported transaction shall not obtain any rights to or interest in such Share Units. 
 7. Dividend Equivalents. From
and after the Crediting Date and until the earlier of (a) the time when the Share Units are paid in accordance with this Agreement or (b) the time when your rights in the Share Units are forfeited in accordance with Section 2(b)
hereof, on the date that Teradata pays a cash dividend (if any) to holders of Shares generally, you shall receive additional Share Units equal to (x) the number of Share Units held by you as of the date of record for such dividend, provided
that the record date occurs on or after the Crediting Date; multiplied by (y) the per Share cash dividend amount; divided by (z) the Fair Market Value per Share on the dividend payment date. The additional Share Units shall be subject to
the same terms and conditions as the Share Units covered by this Agreement, including without limitation the forfeiture provisions of Section 2(b) of this Agreement; provided, however, that for purposes of Section 2(a)(i) of this Agreement
(i) any such additional Share Units issued between the Crediting Date and the first anniversary of the Crediting Date shall vest in two equal installments on the first anniversary of the Crediting Date and the second anniversary of the
Crediting Date, provided that you are continuously employed by Teradata through each such date, and (ii) any such additional Share Units issued between the first anniversary of the Crediting Date and the second anniversary of the Crediting Date
shall vest on the second anniversary of the Crediting Date, provided that you are continuously employed by Teradata through such date. 
 8. Misconduct; Termination for Cause. The Share Units will be forfeited if your employment is terminated by Teradata for Cause or if the Committee determines that you engaged in misconduct in
connection with your employment with Teradata. Further, if your employment is terminated by Teradata for Cause, then, to the extent demanded by the Committee in its sole discretion and permitted by applicable law, you shall (a) return to
Teradata all Shares that you have not disposed of that have been acquired pursuant to this Agreement, and (b) with respect to any Shares acquired pursuant to this Agreement that you have disposed of, pay to Teradata in cash the Fair Market
Value of such Shares on the date acquired. 

 9. Withholding. Teradata has the right to deduct or cause to be deducted from, or
collect or cause to be collected, with respect to the taxation of any Share Units, any federal, state, local, foreign or other taxes required by the laws of the United States or any other country to be withheld or paid with respect to the Share
Units, and you or your legal representative or beneficiary will be required to pay any such amounts. By accepting this award, you consent and direct that, if you are paid through Teradata’s United States payroll system at the time the Share
Units are settled, Teradata’s stock plan administrator will withhold or sell the number of Shares underlying the Share Units as Teradata, in its sole discretion, deems necessary to satisfy such withholding requirements; provided, however, that
if Teradata is required to withhold any taxes prior to settlement of the Share Units, then you agree that Teradata may satisfy those withholding obligations by withholding cash from your compensation otherwise due to you or by any other action as it
may deem necessary to satisfy the withholding obligation. In no event shall the Fair Market Value of the Shares of common stock to be surrendered pursuant to this section to satisfy applicable withholding taxes exceed the minimum amount of taxes
required to be withheld or such other amount that will not result in a negative accounting impact. If you are paid through a non-United States Teradata payroll system, you agree that Teradata may satisfy any withholding obligations by withholding
cash from your compensation otherwise due to you or by any other action as it may deem necessary to satisfy the withholding obligation. You acknowledge that the ultimate liability for all taxes and tax-related items is and remains your
responsibility and may exceed the amount actually withheld by Teradata or the Employer. You also agree that you solely are responsible for filing all relevant documentation that may be required of you in relation to this award or any tax-related
items, such as but not limited to personal income tax returns or reporting statements in relation to the grant or vesting of this award or the subsequent sale of Shares acquired pursuant to such award and the receipt of any dividends or dividend
equivalents. 
 10. Restrictive Covenants. In exchange for the Share Units, you agree that during your employment with
Teradata and, to the extent permitted by applicable law, for a period of twelve (12) months after the termination of employment (or if applicable law mandates a maximum time that is shorter than twelve months, then for a period of time equal to
that shorter maximum period), regardless of the reason for termination, you will not, without the prior written consent of the Chief Executive Officer of Teradata, (a) render services directly or indirectly to, or become employed by, any
Competing Organization (as defined in this Section 10 below) to the extent such services or employment involves the development, manufacture, marketing, sale, advertising or servicing of any product, process, system or service which is the same
or similar to, or competes with, a product, process, system or service manufactured, sold, serviced or otherwise provided by Teradata to its customers and upon which you worked or in which you participated during the last two (2) years of your
Teradata employment; (b) directly or indirectly recruit, hire, solicit or induce, or attempt to induce, any exempt employee of Teradata to terminate his or her employment with or otherwise cease his or her relationship with Teradata; or
(c) solicit the business of any firm or company with which you worked during the preceding two (2) years while employed by Teradata, including customers of Teradata. If you breach the terms of this Section 10, you agree that in
addition to any liability you may have for damages arising from such breach, any unvested Share Units will be immediately forfeited, and, to the extent permitted by applicable law, you agree to pay to Teradata the Fair Market Value of any Share
Units that vested and that were paid during the twelve (12) months prior to the date of termination of your employment. Such Fair Market Value shall be determined as of the date that the Share Units become vested. If you breach the terms of
this Section 10 prior to the end of the Performance Period but after you incur a termination described in Section 3(a) of this Agreement, your award will be forfeited and you will not receive the pro-rata portion of the Share Units.

 As used in this Section 10, “Competing Organization” means an organization
identified as a Competing Organization by the Chief Executive Officer of Teradata for the year in which your employment with Teradata terminates, and any other person or organization which is engaged in or about to become engaged in research on or
development, production, marketing, leasing, selling or servicing of a product, process, system or service which is the same or similar to or competes with a product, process, system or service manufactured, sold, serviced or otherwise provided by
Teradata to its customers. The list of Competing Organizations identified by the Chief Executive Officer is maintained by the Teradata Law Department. 
 11. Arbitration. By accepting this award, you agree that, where permitted by local law, any controversy or claim arising out of or related to your employment relationship with Teradata shall be
resolved by first exhausting any Teradata internal dispute resolution process and policy, and then by arbitration pursuant to such policy. If you are employed outside the United States, where permitted by local law, the arbitration shall be
conducted in the regional headquarters city of the business unit in which you work. The arbitration shall be held before a single arbitrator who is an attorney knowledgeable in employment law. The arbitrator’s decision and award shall be final
and binding and may be entered in any court having jurisdiction. For arbitrations held in the United States, issues of arbitrability shall be determined in accordance with the federal substantive and procedural laws relating to arbitration; all
other aspects shall be interpreted in accordance with the laws of the state in which the headquarters of Teradata is located. Each party shall bear its own attorney’s fees associated with the arbitration and other costs and expenses of the
arbitration shall be borne as provided by the rules of the American Arbitration Association for an arbitration held in the United States, or similar applicable rules for an arbitration held outside the United States. 

Notwithstanding the preceding subparagraph, you acknowledge that if you breach Section 10, Teradata will sustain irreparable injury
and will not have an adequate remedy at law. As a result, you agree that in the event of your breach of Section 10 Teradata may, in addition to any other remedies available to it, bring an action in a court of competent jurisdiction for
equitable relief to preserve the status quo pending appointment of an arbitrator and completion of an arbitration. You stipulate to the exclusive jurisdiction and venue of the state and federal courts located in the location from which
Teradata’s equity programs are administered, for any such proceedings. 
 12. Compensation Recovery Policy. By
accepting this award, you acknowledge and agree that, notwithstanding any other provision of this Agreement to the contrary, you may be required to forfeit or repay any or all of the Share Units pursuant to the terms of the Teradata Corporation
Compensation Recovery Policy (or a successor policy), as the same may be amended to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act or any rules or regulations issued by the Securities and Exchange Commission or applicable
securities exchange. 

 13. Beneficiaries; Successors. 

(a) Without limiting Section 6 of this Agreement, you may designate one or more beneficiaries to receive all or part of any Share
Units to be distributed in case of your death, and you may change or revoke such designation at any time. In the event of your death, any Share Units distributable hereunder that are subject to such a designation will be distributed to such
beneficiary or beneficiaries in accordance with this Agreement. Any other Share Units not designated by you will be distributable to your estate. If there is any question as to the legal right of any beneficiary to receive a distribution hereunder,
the Share Units in question may be transferred to your estate, in which event Teradata will have no further liability to anyone with respect to such Share Units. 
 (b) The provisions of this Agreement shall inure to the benefit of, and be binding upon, your successors, administrators, heirs, legal representatives and assigns, and the successors and assigns of the
Company. 
 14. Severability. The provisions of this Agreement are severable. If any provision of this Agreement is held
to be unenforceable or invalid by a court or other tribunal of competent jurisdiction (including an arbitration tribunal), it shall be severed and shall not affect any other part of this Agreement, which will be enforced as permitted by law.

 15. Amendment. The terms of this award of Share Units as evidenced by this Agreement may be amended by the Teradata
Board of Directors or the Committee. 
 16. Adjustments. The number of Share Units and the number and kind of shares of
stock covered by this Agreement shall be subject to adjustment as provided in Section 14 of the Plan. 
 17. Plan
Governs. In the event of a conflict between the terms and conditions of this Agreement and the terms and conditions of the Plan, the terms and conditions of the Plan shall prevail, except that with respect to matters involving choice of law, the
terms and conditions of Section 10 of this Agreement shall prevail. 
 18. Dividend; Voting Rights. You shall not
possess any incidents of ownership (including, without limitation, dividend and voting rights) in the Shares underlying the Share Units credited to your Account until such Shares have been delivered to you in accordance with Section 2,
Section 3 or Section 4 hereof. The obligations of the Company under this Agreement will be merely that of an unfunded and unsecured promise of the Company to deliver Shares in the future, and your rights will be no greater than that of an
unsecured general creditor. No assets of the Company will be held or set aside as security for the obligations of the Company under this Agreement. 
 19. No Employment Contract or Acquired Rights. Nothing contained in this Agreement shall confer upon you any right with respect to continuance of employment by Teradata, nor limit or affect in any
manner the right of Teradata to terminate your employment or adjust your compensation. Furthermore, nothing contained in this Agreement shall confer upon you any right to receive any future Share Units or awards under the Plan or the inclusion of
the value of any awards in the calculation of severance payments, if any, upon termination of employment. 

 20. Non-U.S. Employees. Notwithstanding any provision herein, if the Plan or your
employment with Teradata is subject to the rules and regulations of one or more non-United States jurisdictions, then your participation in the Plan shall be subject to any such rules and regulations and any special terms and conditions as set forth
in any appendix for your country (the “Appendix”). Moreover, if you relocate to one of the countries included in the Appendix, the special terms and conditions for such country will apply to you, to the extent the Company determines
that the application of such terms and conditions is necessary or advisable in order to comply with local law or facilitate the administration of the Plan. The Company also reserves the right to impose other requirements on your participation in the
Plan to the extent the Company determines it necessary or advisable in order to comply with local law or facilitate the administration of the Plan and to require you to sign any additional agreements or undertakings that may be necessary to
accomplish the foregoing. The Appendix constitutes part of this Agreement. 
 You also understand and agree that any
cross-border cash remittance made in relation to this award, including the transfer of proceeds received upon the sale of Shares, must be made through a locally authorized financial institution or registered foreign exchange agency and may require
you to provide to such financial institution or agency certain information regarding the transaction. Moreover, you understand and agree that the Company is neither responsible for any foreign exchange fluctuation between your local currency and the
United States Dollar (or the selection by Teradata or the Employer in its sole discretion of an applicable foreign currency exchange rate) that may affect the value of this award (or the calculation of income or any Tax-Related Items thereunder) nor
liable for any decrease in the value of Shares or this award. In addition, the ownership of Shares or assets and holding of bank or brokerage account abroad may subject you to reporting requirements imposed by tax, banking, and/or other authorities
in your country, and you understand and agree that you solely are responsible for complying with such requirements. 
 21.
Acceptance of Terms. By accepting any benefit under this Agreement, you and each person claiming under or through you shall be conclusively deemed to have indicated their acceptance and ratification of, and consent to, all of the terms and
conditions of this Agreement and the Plan and any action taken under this Agreement or the Plan by the Committee, the Board or Teradata, in any case in accordance with the terms and conditions of this Agreement. 

22. Communications and Electronic Delivery. Teradata may, in its sole discretion, decide to deliver any documents related to
current or future participation in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained by Teradata
or a third party designated by Teradata. If you have received this Agreement or any other document related to the Plan translated into a language other than English and if the translated version is different than the English version, the English
version will control. 

 23. Data Privacy Consent. You hereby explicitly and unambiguously consent to the
collection, use and transfer, in electronic or other form, of your personal data as described in this Agreement and any other Share Unit grant materials by and among, as applicable, the Employer and Teradata for the exclusive purpose of
implementing, administering and managing your participation in the Plan. 
 You understand that Teradata and the Employer may
hold certain personal information about you, including, but not limited to, your name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or
directorships held in Teradata, details of all Share Units or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in your favor, for the purpose of implementing, administering and managing the Plan
(“Data”). 
 You understand that Data will be transferred to any third parties assisting Teradata with the
implementation, administration and management of the Plan. You understand the recipients of the Data may be located in your country, in the United States or elsewhere, and that the recipients’ country (e.g., the United States) may have
different data privacy laws and protections than your country. You understand that you may request a list with the names and addresses of any potential recipients of the Data by contacting your local human resources representative. You authorize
Teradata and the recipients which may assist Teradata (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of
implementing, administering and managing your participation in the Plan. You understand that Data will be held only as long as is necessary to implement, administer and manage your participation in the Plan. You understand that you may, at any time,
view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing your local human resources
representative. You understand, however, that refusing or withdrawing your consent may affect your ability to participate in the Plan. For more information on the consequences of your refusal to consent or withdrawal of consent, you understand that
you may contact your local human resources representative.

DESIGNATION AND TERMS OF THE NEW NOTES; FORMS 

SECTION 2.01. Establishment of Series. 

(a) There is hereby created a series of Securities to be known and designated as the “3.875% Senior Notes due 2024” to be issued in
aggregate principal amount of $250,000,000. Additional Securities, without limitation as to amount, having substantially the same terms as the New Notes (except a different issue date, a different issue price and bearing interest from the last
Interest Payment Date to which interest has been paid or duly provided for on the New Notes, and, if no interest has been paid, from February 27, 2014), may also be issued by the Issuer pursuant to the Indenture without the consent of the
existing Holders of the New Notes; provided, that such additional Securities must be part of the same issue as the New Notes for U.S. federal income tax purposes or, if they are not part of the same issue for such purposes, such additional
Securities must be issued with a separate CUSIP number. Such additional Securities shall be part of the same series as the New Notes. The “Stated Maturity” of the New Notes is March 1, 2024; the principal amount of the New
Notes shall be payable on such date unless the New Notes are earlier redeemed in accordance with the terms of the Indenture. 
 (b) The New
Notes will bear interest from the Original Issue Date, or from the most recent date to which interest has been paid or duly provided for, at the rate of 3.875% per annum stated therein until the principal thereof is paid or made available for
payment. Interest will be payable semi-annually on each Interest Payment Date and at Maturity, as provided in the form of the New Note in Section 2.03 and Section 2.04 hereof. 

(c) The Record Date referred to in Section 2.3(f)(4) of the Original Indenture for the payment of the interest on any New Note payable on
any Interest Payment Date (other than on the Stated Maturity) shall be the February 15 and August 15 next preceding the relevant Interest Payment Date (whether or not a Business Day) except that interest payable on the Stated Maturity
shall be paid to the Person to whom the principal amount is paid. 
 (d) The payment of the principal of, and premium (if any) and interest
on, the New Notes shall not be secured by a security interest in any property. 
 (e) The New Notes shall be redeemable at the option of the
Issuer, in whole or in part, at any time and from time to time, upon not less than 30, nor more than 60 days’ notice at a redemption price equal to 100% of the principal amount of such New Notes being redeemed plus, in the case of any
redemption prior to December 1, 2023 (three months prior to Stated Maturity), the Applicable Premium, if any, thereon at the time of redemption, together with (at any time) accrued and unpaid interest, if any, thereon to, but not including, the
redemption date. In no event will the redemption price ever be less than 100% of the principal amount of the New Notes being redeemed plus accrued interest, if any, thereon to the redemption date. Notwithstanding Section 11.2 of the Indenture,
notice of the foregoing redemption occurring prior to December 1, 2023 (three months prior to Stated Maturity) need not set forth the redemption price therefor but only the manner of calculation thereof. The Issuer shall give the Trustee notice
of such redemption price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

  
 6 

 (f) The New Notes shall not be convertible. 

(g) The New Notes will not be subordinated to the payment of Senior Debt. 

(h) The Issuer will not pay any additional amounts on the New Notes held by a Person who is not a U.S. person (as defined in Regulation S
under the Securities Act) in respect of any tax, assessment or government charge withheld or deducted. 
 (i) The events specified in Events
of Default with respect to the New Notes shall include the events specified in Article V hereof. In addition to the covenants set forth in Article Three of the Original Indenture, the Holders of the New Notes shall have the benefit of the covenants
of the Issuer set forth in Article III hereof. The provisions of Section 9.1 and Section 9.2 of the Original Indenture shall be amended and restated solely with respect to the New Notes as specified in Article IV hereof. 

(j) The New Notes are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000
in excess thereof. 
 (k) The provisions of Article VI, Article VII and Article VIII hereof shall apply to the New Notes as specified
therein. 
 SECTION 2.02. Forms Generally. The New Notes and Trustee’s certificate of authentication shall be in substantially
the form set forth in this Article II, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers executing such New Notes, as evidenced by their execution thereof. 

The definitive New Notes shall be printed, lithographed or engraved on steel engraved borders or may be produced in any other manner, all as
determined by the officers executing such New Notes, as evidenced by their execution thereof. 
 SECTION 2.03. Form of Face of New
Note.

 ISIN No.: US125896BM13 

CMS Energy Corporation, a corporation duly organized and existing under the laws of the State of Michigan (herein called the
“Issuer”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of Two Hundred Fifty
Million Dollars on March 1, 2024 (“Stated Maturity”) and to pay interest thereon from February 27, 2014 (the “Original Issue Date”) or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, semi-annually in arrears on March 1 and September 1 in each year, commencing on September 1, 2014 (each an “Interest Payment Date”), to the Persons in whose names the New Notes are
registered at 5:00 p.m., New York City time, on the February 15 and August 15 (whether or not a Business Day) next preceding the relevant Interest Payment Date (each a “Record Date”), and on the Stated Maturity, to the
Person to whom the principal amount is paid, at the rate of 3.875% per annum, until the principal hereof is paid or made available for payment. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a
360-day year of twelve 30-day months. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the Person in whose name this New Note (or one or more
Predecessor New Notes) is registered at 5:00 p.m., New York City time, on a subsequent record date (which shall be not less than five Business Days prior to the date of payment of such defaulted interest) for the payment of such defaulted interest
to be fixed by the Trustee, notice whereof shall be given to Holders of New Notes not less than 15 calendar days preceding such subsequent Record Date. 

Payment of the principal of (and premium, if any) and interest on this New Note will be made at the office or agency of the Issuer maintained
for that purpose in New York, New York (the “Place of Payment”), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Issuer payment of interest (other than interest payable at Maturity) may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire
transfer to an account designated by such Person not later than ten days prior to the date of such payment.

 SECTION 2.04. Form of Reverse of New Note. 

This 3.875% Senior Note due 2024 is one of a duly authorized issue of securities of the Issuer (herein called the “New
Notes”), issued and to be issued under an Indenture, dated as of September 15, 1992 (as supplemented by the Thirtieth Supplemental Indenture, dated as of February 27, 2014 and as further amended or supplemented from time to time,
the “Indenture”), between the Issuer and The Bank of New York Mellon, a New York banking corporation (ultimate successor to NBD Bank, National Association), as Trustee (herein called the “Trustee”, which term
includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer,
the Trustee, and the Holders of the New Notes and of the terms upon which the New Notes are, and are to be, authenticated and delivered. This New Note is one of the series designated on the face hereof, issued in an initial aggregate principal
amount of $250,000,000. Additional Securities, without limitation as to amount, having substantially the same terms as the New Notes (except a different issue date, a different issue price and bearing interest from the last Interest Payment Date to
which interest has been paid or duly provided for on the New Notes, and, if no interest has been paid, from February 27, 2014), may also be issued by the Issuer pursuant to the Indenture without the consent of the existing Holders of the New
Notes; provided, that such additional Securities must be part of the same issue as the New Notes for U.S. federal income tax purposes or, if they are not part of the same issue for such purposes, such additional Securities must be issued with
a separate CUSIP number. Such additional Securities shall be part of the same series as the New Notes. 

  
 9 

 No sinking fund is provided for the New Notes. 

The New Notes are subject to redemption at the option of the Issuer, in whole or in part, upon not less than 30 nor more than 60 days’
notice as provided in the Indenture at any time and from time to time, at a redemption price equal to 100% of the principal amount of such New Notes being redeemed plus, in the case of any redemption prior to December 1, 2023 (three months
prior to Stated Maturity), the Applicable Premium, if any, thereon at the time of redemption, together with (at any time) accrued and unpaid interest, if any, thereon to, but not including, the redemption date, but interest installments whose Stated
Maturity is on or prior to such redemption date will be payable to the Holder of record at the close of business on the relevant Record Date referred to on the face hereof, all as provided in the Indenture. In no event will the redemption price ever
be less than 100% of the principal amount of the New Notes being redeemed plus accrued interest to the redemption date. 
 The following
definitions are used to determine the Applicable Premium: 
 “Applicable Premium” means, with respect to a New Note (or
portion thereof) being redeemed at any time prior to December 1, 2023, the excess of (A) the present value at such time of the principal amount of such New Note (or portion thereof) being redeemed plus all interest payments due on such New
Note (or portion thereof) after the redemption date (but, for the avoidance of doubt, excluding any portion of such payments of interest accrued to the redemption date), which present value shall be computed using a discount rate equal to the
Treasury Rate plus 17 basis points, over (B) the principal amount of such New Note (or portion thereof) being redeemed at such time. For purposes of this definition, the present values of the interest and principal payments will be determined
in accordance with generally accepted principles of financial analysis. 
 “Treasury Rate” means the yield to maturity at
the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two Business Days prior to
the redemption date or, in the case of defeasance, prior to the date of deposit (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the then remaining average life to
stated maturity of the New Notes being redeemed; provided, however, that if the average life to stated maturity of the New Notes being redeemed is not equal to the constant maturity of a United States Treasury security for which a weekly average
yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given. 

If an Event of Default with respect to this New Note shall occur and be continuing, the principal of this New Note may be declared due and
payable in the manner and with the effect provided in the Indenture. 
 In any case where any Interest Payment Date, redemption date, Stated
Maturity or Maturity of any New Note shall not be a Business Day, then (notwithstanding any other provision of the Indenture or this New Note) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on
the next succeeding Business Day with 

  
 10 

 
the same force and effect as if made on the Interest Payment Date, redemption date or Stated Maturity or at Maturity; provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, redemption date, Stated Maturity or Maturity, as the case may be, to such Business Day. 

The Trustee and the Paying Agent shall return to the Issuer upon written request any money or property held by them for the payment of any
amount with respect to the New Notes that remains unclaimed for two years, provided, however, that the Trustee or such Paying Agent, before being required to make any such return, shall at the expense of the Issuer cause to be published once
in a newspaper of general circulation in The City of New York or mail to each such Holder notice that such money or property remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such
publication or mailing, any unclaimed money or property then remaining shall be returned to the Issuer. After return to the Issuer, Holders entitled to the money or property must look to the Issuer for payment as general creditors unless an
applicable abandoned property law designates another Person. 
 The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this New Note or (ii) certain restrictive covenants and Events of Default with respect to this New Note, in each case upon compliance with certain conditions set forth therein. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Issuer and the rights of the Holders of all outstanding New Notes under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in principal amount of Securities of all series
(including the New Notes) then outstanding and affected (voting as one class). 
 The Indenture permits the Holders of a majority in
principal amount of Securities of all series at the time outstanding with respect to which a default shall have occurred and be continuing (voting as one class) to waive on behalf of the Holders of all outstanding Securities of such series any past
default by the Issuer, provided that no such waiver may be made with respect to a default in the payment of the principal of or the interest on any Security of such series, the default in the payment of the redemption price with respect to
the New Notes, or the default by the Issuer in respect of certain covenants or provisions of the Indenture, the modification or amendment of which must be consented to by the Holder of each outstanding Security of each series affected. 

As set forth in, and subject to, the provisions of the Indenture, no Holder of any New Note will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default, the Holders of not less than 25% in principal amount of the outstanding
Securities of each affected series (voting as one class) shall have made written request, and offered reasonable indemnity against costs, expenses and liabilities, to the Trustee to institute such proceeding as trustee, and the Trustee shall not
have received from the Holders of a majority in principal amount of the outstanding Securities of each affected series (voting as one class) a direction inconsistent with such request and shall have failed to institute such proceeding

  
 11 

 
within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of (and premium, if
any) or any interest on this New Note on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no
provision of this New Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this New Note at the times, place and rate, and in the
coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of
this New Note is registrable in the Security Register, upon surrender of this New Note for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this New Note are payable,
duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Security Registrar duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or
more new New Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The New Notes are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, New Notes are exchangeable for a like aggregate principal amount of New Notes and of like tenor of a different authorized denomination, as requested
by the Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Issuer
may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 The Issuer shall
not be required to (i) issue, exchange or register the transfer of this New Note for a period of 15 days next preceding the mailing of the notice of redemption of New Notes or (ii) exchange or register the transfer of any New Note or any
portion thereof selected, called or being called for redemption, except in the case of any New Note to be redeemed in part, the portion thereof not so to be redeemed. 

Prior to due presentment of this New Note for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this New Note is registered as the owner hereof for all purposes, whether or not this New Note be overdue, and neither the Issuer, the Trustee nor any such agent shall be affected by notice to the contrary. 

All terms used in this New Note without definition which are defined in the Indenture shall have the meanings assigned to them in the
Indenture. In case of any conflict between this New Note and the Indenture, the provisions of the Indenture shall control. 
  

  
 12 

 SECTION 2.05. Form of Trustee’s Certificate of Authentication. The Trustee’s
certificate of authentication shall be in substantially the following form:

property of any character, including without limitation any shares of Capital Stock of Consumers or Enterprises, without making effective provision whereby the New Notes shall (so long as any such other creditor shall be so secured) be equally and
ratably secured (along with any other creditor similarly entitled to be secured) by a direct Lien on all property subject to such Lien, provided, however, that the foregoing restrictions shall not apply to:

secure Indebtedness incurred solely for the purpose of financing the acquisition of any such property to be subject to such Liens, or Liens existing on any such property at the time of
acquisition, or extensions, renewals or replacements of any of the foregoing for the same or a lesser amount, provided that no such Lien shall extend to or cover any property other than the property being acquired and no such extension,
renewal or replacement shall extend to or cover property not theretofore subject to the Lien being extended, renewed or replaced, and provided, further, that the aggregate principal amount of the Indebtedness at any one time
outstanding secured by Liens permitted by this Section 3.02(iv) shall not exceed $10,000,000; and 
 (v) Liens not
otherwise permitted by Section 3.02(i) through Section 3.02(iv) hereof securing Indebtedness of the Issuer; provided that on the date such Liens are created, and after giving effect to such Indebtedness, the aggregate principal
amount at maturity of all of the secured Indebtedness of the Issuer at such date shall not exceed 10% of Consolidated Net Tangible Assets at such date. 

SECTION 3.03. Reporting. For purposes of Section 4.3(a) of the Original Indenture solely with respect to the New Notes (but not

ARTICLE VIII 
 GLOBAL
NOTES 
 The New Notes will be issued initially in the form of one or more Global Notes. “Global Note” means a
registered New Note evidencing one or more New Notes issued to a depositary (the “Depositary”) or its nominee, in accordance with this Article VIII and bearing the legend prescribed in this Article VIII. The Issuer hereby designates
The Depository Trust Company as the Depositary. The Issuer shall execute and the Trustee shall, in accordance with this Article VIII and the Issuer Order with respect to the New Notes, authenticate and deliver one or more Global Notes in temporary
or permanent form that (i) shall represent and shall be denominated in an aggregate amount equal to the aggregate principal amount of the New Notes to be represented by such Global Note or Global Notes, (ii) shall be registered in the name
of the Depositary for such Global Note or Global Notes or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions and (iv) shall bear a legend
substantially to the following effect: “Unless this Global Note is presented by an authorized representative of the Depositary to the Issuer or its agent for registration of transfer, exchange or payment, and any certificate issued is
registered in the name of a nominee of the Depositary or in such other name as is requested by an authorized representative of the Depositary (and any payment is made to such nominee of the Depositary or to such other entity as is requested by an
authorized representative of the Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof has an interest herein.” 

  
 17 

 Notwithstanding Section 2.8 of the Original Indenture, unless and until it is exchanged in
whole or in part for New Notes in definitive form, a Global Note representing one or more New Notes may not be transferred except as a whole by the Depositary to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for New Notes or a nominee of such successor Depositary. 

If at any time the Depositary for the New Notes is unwilling or unable to continue as Depositary for the New Notes, defaults in the
performance of its duties as Depositary or ceases to be a clearing agency registered under the Exchange Act or other applicable statute or regulation, the Issuer shall appoint a successor Depositary with respect to the New Notes. If a successor
Depositary for the New Notes is not appointed by the Issuer by the earlier of (x) 90 days from the date the Issuer receives notice to the effect that the Depositary is unwilling or unable to act, or the Issuer determines that the Depositary is
unable to act, or (y) the effectiveness of the Depositary’s resignation or failure to fulfill its duties as Depositary, the Issuer will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and delivery of
definitive New Notes, will authenticate and deliver New Notes in definitive form in an aggregate principal amount equal to the principal amount of the Global Note or Global Notes representing such New Notes in exchange for such Global Note or Global
Notes. 
 If the Issuer so specifies with respect to any New Notes, an owner of a beneficial interest in a Global Note representing the New
Notes may, on terms acceptable to the Issuer and the Depositary for the Global Note, receive individual New Notes in exchange for the beneficial interest. In any such instance, an owner of a beneficial interest in a Global Note will be entitled to
physical delivery in definitive form of New Notes represented by the Global Note equal in principal amount to the beneficial interest, and to have the New Notes registered in its name. New Notes so issued in definitive form will be issued as
registered New Notes in minimum denominations of $2,000 and in $1,000 integral multiples, unless otherwise specified by the Issuer. 
 Upon
the exchange of a Global Note for New Notes in definitive form, such Global Note shall be cancelled by the Trustee. New Notes in definitive form issued in exchange for a Global Note pursuant to this Article VIII shall be registered in such names and
in such authorized denominations as the Depositary for such Global Note, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or Security Registrar. The Trustee shall deliver such New Notes to
the Persons in whose names such New Notes are so registered.
