Form of Comerica Incorporated Restricted Stock Unit Award Agreement (cliff vesting)

THIS AGREEMENT (this “Agreement”) between Comerica Incorporated (the “Company”) and NAME (the “Award Recipient”) is effective as of GRANT DATE (the “Effective Date”). Any undefined terms appearing herein as defined terms shall have the same meaning as they do in the Comerica Incorporated 2006 Long-Term Incentive Plan, as amended and/or restated from time to time, or any successor plan thereto (the “Plan”). The Company will provide a copy of the Plan to the Award Recipient upon request.

1. Award of Restricted Stock Units. Pursuant to the provisions of the Plan, the Company hereby awards the Award Recipient, subject to the terms and conditions of the Plan (incorporated herein by reference), and subject further to the terms and conditions in this Agreement, XXXX restricted stock units (“RSUs”) (the “Award”). Each RSU shall represent an unfunded, unsecured right for the Award Recipient to receive one (1) share of the Company's common stock, par value $5.00 per share (the “Common Stock”), as described in this Agreement.

2. Ownership Rights. The Award Recipient has no voting or other ownership rights in the Company arising from the Award of RSUs under this Agreement prior to the delivery of shares of Common Stock upon the vesting of RSUs underlying the Award and delivery of shares of Common Stock in settlement thereof.

3. Dividend Equivalents. If cash dividends are declared by the Company’s Board of Directors on the Common Stock on or after the Effective Date and prior to the Settlement Date (as defined below), cash dividend equivalents (the “Dividend Equivalents”) shall accrue on the shares of Common Stock underlying RSUs, whether such RSUs are vested or unvested, which Dividend Equivalents shall be subject to vesting and forfeiture on the same terms and conditions as the underlying RSUs. Such Dividend Equivalents will be in an amount of cash per RSU equal to the cash dividend paid with respect to a share of outstanding Common Stock and shall be credited on the declaration date applicable to shares of Common Stock. The Dividend Equivalents accrued prior to the Settlement Date will be paid to the Award Recipient with respect to all vested RSUs as soon as administratively feasible after the Settlement Date (but in no event later than 45 days following the Settlement Date). The Dividend Equivalents accrued on shares of Common Stock underlying RSUs that do not vest and are forfeited shall be forfeited for no consideration on the date such RSU is forfeited.

4. Vesting of Award. The unvested portion of the Award is subject to forfeiture. Subject to the terms of the Plan and this Agreement, including without limitation, fulfillment of the employment requirements in paragraph 9, the Award will vest in accordance with the following schedule (except in the case of the Award Recipient’s earlier Separation from Service (as defined in paragraph 9) due to death or Disability or an earlier Change of Control of the Company, as set forth in paragraph 7): 100% of the RSUs covered by the Award shall vest on the third anniversary of the Effective Date of this Award (or, if such date is not a business day, the business day immediately preceding such date) (the “Vesting Date”).

5. Special Vesting and Forfeiture Terms.

(a)Forfeiture Resulting From Acts Occurring During the Grant Year. Notwithstanding any other provision of this Agreement, if it shall be determined at any time subsequent to the Effective Date and prior to the Settlement Date (or, in the case of a termination due to death or Disability, the date of Separation from Service) that the Award Recipient has, during the calendar year in which the Effective Date occurs (the “Grant Year”), (i) failed to comply with Company policies and procedures, including the Code of Business Conduct and Ethics or the Senior Financial Officer Code of Ethics (if applicable), (ii) violated any law or regulation, (iii) engaged in negligent or willful misconduct, (iv) engaged in activity resulting in a significant or material Sarbanes-Oxley control deficiency, or (v) demonstrated poor risk management or lack of judgment in discharge of Company duties, and such failure, violation, misconduct, activity or behavior (1) demonstrates an inadequate sensitivity to the inherent risks of Award Recipient’s business line or functional area, and (2) results in, or is reasonably likely to result in, a material adverse impact (whether financial or reputational) on the Company or Award Recipient’s business line or functional area, all or part of the Award granted under this Agreement that has not yet become vested at the time of such determination may be cancelled and forfeited. “Inadequate sensitivity” to risk is demonstrated by imprudent activities that subject the Company to risk outcomes in future periods, including risks that may not be apparent at the time the activities are undertaken.

(b)Forfeiture of Award for Acts Occurring in Years Other Than the Grant Year. Notwithstanding any other provisions of this Agreement, if the Award Recipient receives one or more equity awards in any calendar years other than the Grant Year (an “Other Grant Year”) pursuant to an Award Agreement that contains a clause substantially similar to paragraph (a) above, and it shall be determined that Award Recipient, as a result of risk-related behavior, should be subject to the forfeiture of all or part of any such award granted in such Other Grant Year in accordance with the terms of such clause, then the unvested portion of the Award granted under this Agreement shall be subject to forfeiture to the extent necessary to equal the Unsatisfied Forfeiture Value (as defined below). The term “Unsatisfied Forfeiture Value” shall mean the value (as determined by the Committee in its absolute discretion) of any portion of the Award determined by the Committee to be subject to forfeiture with respect to the Other Grant Year (without regard to whether or not some portion thereof has already vested) that has in fact vested prior to such determination by the Committee. All or a portion of the RSUs granted under this Agreement that have not yet become vested shall be subject to forfeiture in order to satisfy as much as possible of the Unsatisfied Forfeiture Value, and the valuation of the Award for such purpose shall be determined in the absolute discretion of the Committee.

(a)In General. Subject to the terms of the Plan, upon vesting, the Award will be settled in Common Stock and the settlement of the Award shall occur as soon as reasonably practicable following the Vesting Date (or if such date is not a business day, the business day immediately preceding such date); or, in the case of (i) the Award Recipient’s Separation from Service due to death or Disability or (ii) a Change of Control (as defined in clause A of Exhibit A of the Plan), settlement of the Award shall occur as of such earlier date set forth in paragraph 7 (the “Settlement Date”). As soon as reasonably practicable following the Settlement Date, the Company shall issue (in certificate form or book-entry registration, as described in paragraph 6(c)) to the Award Recipient (or, in the case of the Award Recipient's death, to the Award Recipient's designated beneficiary or estate, as applicable or, in the case of the Award Recipient's Disability, to the Award Recipient's guardian or legal representative, if applicable and if permissible under applicable law) a number of whole shares of Common Stock (rounded down to a whole number) equal to the aggregate number of RSUs in respect of the Award (the “Settlement Shares”).

(b)Termination of Rights. Upon the issuance of the Settlement Shares in settlement of the vested RSUs in respect of the Award, the Award shall be settled in full and the Award Recipient (or his or her designated beneficiary or estate, in the case of death) shall have no further rights with respect to the Award, other than with respect to the payment of the Dividend Equivalents accrued with respect to such vested RSUs.

(c)Certificates or Book Entry. On the Settlement Date, the Company shall, at the discretion of the Committee or its designee, either issue one or more certificates in the Award Recipient's name (or, in the case of death, to the Award Recipient’s designated beneficiary, if any) for such Settlement Shares or evidence book-entry registration of the Settlement Shares in the Award Recipient's name (or, in the case of death, to the Award Recipient's designated beneficiary, if any). No fractional shares of Common Stock shall be issued in settlement of the RSUs.

(d)Conditions to Delivery. Notwithstanding any other provision of this Agreement, the Company shall not be required to evidence book-entry registration or issue or deliver any certificate or certificates representing the Settlement Shares in the event the Company reasonably anticipates that such registration, issuance or delivery would violate Federal securities laws or other applicable law; provided that the Company must evidence book-entry registration or issue or deliver said certificate or certificates at the earliest date at which the Company reasonably anticipates that such registration, issuance or delivery would not cause such violation.

(e)Legends. The Settlement Shares shall be subject to such stop transfer orders and other restrictions as the Committee may deem reasonably advisable under the Plan or the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which such Settlement Shares are listed, any applicable Federal or state laws or the Company's Certificate of Incorporation and Bylaws, and the Committee may cause a legend or legends to be put on or otherwise apply to any certificates or book-entry position representing the Settlement Shares to make appropriate reference to such restrictions.

7. Vesting and Settlement on Change of Control and Separation from Service Due to Death or Disability. Notwithstanding anything in this Agreement to the contrary:

(a)Upon a Change of Control, the Award shall immediately and fully vest, and such Award shall be settled as soon as reasonably practicable following the date of such Change of Control.

(b)        In the event of the Award Recipient's Separation from Service due to death or Disability, prior to the Vesting Date, the Award shall immediately and fully vest effective as of the date of the Award Recipient’s Separation from Service due to death or Disability, and such Award shall be settled as soon as reasonably practicable following the date of such Award Recipient's Separation from Service due to death or Disability.

8. Cancellation of Award. The Committee has the right to cancel for no consideration all or any portion of the Award in accordance with Section 4 of the Plan if the Committee determines in good faith that the Award Recipient has done any of the following: (i) committed a felony; (ii) committed fraud; (iii) embezzled; (iv) disclosed confidential information or trade secrets; (v) was terminated for Cause; (vi) engaged in any activity in competition with the business of the Company or any Subsidiary or Affiliate of the Company; or (vii) engaged in conduct that adversely affected the Company. The Delegate shall have the power and authority to suspend the vesting of or the right to receive the Settlement Shares in respect of all or any portion of the Award if the Delegate makes in good faith the determination described in the preceding sentence. Any such suspension of an Award shall remain in effect until the suspension shall be presented to and acted on by the Committee at its next meeting. This paragraph 8 shall have no application following a Change of Control of the Company.

9. Employment Requirements. Except as provided in this Agreement, for an Award Recipient to vest in and not forfeit the Award, the Award Recipient must remain employed by the Company or one of its Affiliates until the Vesting Date. If there is a Separation from Service for any reason (other than due to death or Disability) before the Vesting Date, the Award Recipient will forfeit the Award and the corresponding Dividend Equivalents, effective immediately as of the date of Separation from Service, unless the Committee determines otherwise. For purposes of this Agreement, the term “Separation from Service” means a “Termination of Employment” as defined in the Plan (subject to the last sentence of paragraph 17(a)).

10. No Right to Continued Employment. Nothing in the Plan or this Agreement shall confer on the Award Recipient any right to continue in the employment of the Company or its Affiliates for any given period or on any specified terms nor in any way affect the Company's or its Affiliates' right to terminate the Award Recipient’s employment without prior notice at any time for any reason or for no reason.

11. Transferability. Unless otherwise determined by the Committee, the RSUs subject to the Award (including, without limitation, the Dividend Equivalents) may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Award Recipient otherwise than by will or by the laws of intestacy, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Subsidiary or Affiliate; provided, however, that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

12. Administration; Amendment. The Award has been made pursuant to a determination by the Committee and/or the Board of Directors of the Company, and the Committee shall have plenary authority to interpret, in its sole and absolute discretion, any provision of this Agreement and to make any determinations necessary or advisable for the administration of this Agreement. All such interpretations and determinations shall be final and binding on all persons, including the Company, the Award Recipient, his or her beneficiaries and all other interested parties. Subject to the terms of the Plan, this Agreement may be amended, in whole or in part, at any time by the Committee; provided, however, that no amendment to this Agreement may adversely affect the Award Recipient's rights under this Agreement without the Award Recipient's consent except such an amendment made to cause the Award to comply with applicable law, stock exchange rules or accounting rules, including as permitted under paragraph 17(b).

13. Binding Nature of Plan. The Award is subject to the Plan. The Award Recipient agrees to be bound by all terms and provisions of the Plan and related administrative rules and procedures, including, without limitation, terms and provisions and administrative rules and procedures adopted and/or modified after the granting of the Award. If any provisions hereof are inconsistent with those of the Plan, the provisions of the Plan shall control, except to the extent expressly modified herein pursuant to authority granted under the Plan.

14. Compliance with Laws and Regulations. The Award and the obligation of the Company to deliver the Settlement Shares subject to the Award are subject to compliance with all applicable laws, rules and regulations, to receipt of any approvals by any government

or regulatory agency as may be required, and to any determinations the Company may make regarding the application of all such laws, rules and regulations.

15. Notices. Any notice to the Company under this Agreement shall be in writing to the following address or facsimile number: Human Resources - Executive Compensation, Comerica Incorporated, 1717 Main Street, MC 6515, Dallas, TX 75201; Facsimile Number: 214 ###-###-####. The Company will address any notice to the Award Recipient to his or her current address according to the Company's personnel files. All written notices provided in accordance with this paragraph 15 shall be deemed to be given when (a) delivered to the appropriate address(es) by hand or by a nationally recognized overnight courier service (costs prepaid); (b) sent by facsimile to the appropriate facsimile number, with confirmation by telephone of transmission receipt; or (c) received by the addressee, if sent by U.S. mail to the appropriate address or by Company inter-office mail to the appropriate mail code. Either party may designate in writing some other address or facsimile number for notice under this Agreement.

16. Withholding. The Award Recipient authorizes the Company to withhold from his or her compensation, including RSUs subject to the Award and the Settlement Shares issuable hereunder, to satisfy any income and employment tax withholding obligations in connection with the Award. No later than the date as of which an amount first becomes includible in the gross income of the Award Recipient for Federal income tax purposes with respect to any Settlement Shares subject to the Award, the Award Recipient shall pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, all Federal, state and local income and employment taxes that are required by applicable laws and regulations to be withheld with respect to such amount. The Award Recipient agrees that the Company may delay delivery of the Settlement Shares until proper payment of such taxes has been made by the Award Recipient. If required pursuant to the Company’s policy as applied to the Award Recipient or elected by the Award Recipient, to the extent permitted by law, tax withholding obligations in respect of the Award shall be satisfied by authorizing the Company to withhold (provided the amount withheld does not exceed the maximum statutory tax rate in the Award Recipient’s applicable tax jurisdiction or such lesser amount as is necessary to avoid adverse accounting treatment for the Company) from the Settlement Shares otherwise issuable to the individual pursuant to the settlement of the Award, a number of shares having a Fair Market Value, as of the Tax Withholding Date, which will satisfy the amount of the withholding tax obligation. Further, unless determined otherwise by the Committee, the Award Recipient may satisfy such obligations under this paragraph 16 by any method authorized under Section 9 of the Plan.

17. Section 409A of the Code.

(a)The Award is intended to qualify for the “short-term deferral” exception under Section 409A of the Code. To the extent that the Award is construed to be nonqualified deferred compensation subject to Section 409A of the Code, the Company shall use its reasonable efforts to operate, administer, construe and interpret this Agreement in a manner that minimizes adverse tax consequences to the Award Recipient and is consistent with the requirements of Section 409A of the Code. Each payment of compensation under this Agreement shall be treated as a separate payment of compensation. In no event may the Award Recipient, directly or indirectly, designate the calendar year of any payment or distribution under this Agreement. Notwithstanding anything contained in this Agreement to the contrary, with respect to any portion of the Award that constitutes nonqualified deferred compensation under Section 409A of the Code, to the extent required for compliance with Section 409A of the Code and/or to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, the administrative provisions in Section 8 of the Plan shall apply and an Award Recipient shall not be considered to have experienced a Separation from Service for purposes of the Award, and no payments or issuances that are to be made upon Separation from Service under this Agreement shall be made, unless and until the Award Recipient experiences a “separation from service” within the meaning of Section 409A of the Code.

(b)This Agreement shall be subject to amendment, with or without advance notice to the Award Recipient, and on a prospective or retroactive basis, including, but not limited to, amendment in a manner that adversely affects the rights of the Award Recipient, to the extent necessary to effect compliance with Section 409A of the Code. Notwithstanding anything contained in this Agreement or the Plan, the Company shall have no liability whatsoever for or in respect of any decision to take action to attempt to comply with Section 409A of the Code, any omission to take such action or for the failure of any such action taken by the Company to so comply.

19. Voluntary Participation. Participation in the Plan is voluntary. The value of the Award is an extraordinary item of compensation outside the scope of the Award Recipient’s employment contract, if any. As such, the Award is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

20. Force and Effect. The various provisions of this Agreement are severable in their entirety. Any judicial or legal determination of invalidity or unenforceability of any one provision shall have no effect on the continuing force and effect of the remaining provisions.

21. Successors. This Agreement shall be binding upon and inure to the benefit of the successors of the respective parties.

22. Applicable Law. The validity, construction and effect of this Agreement and any rules and regulations relating to this Agreement shall be determined in accordance with the laws of the State of Delaware, unless preempted by Federal law, and also, consistent with paragraph 17, in accordance with Section 409A of the Code and any interpretive authorities promulgated thereunder.

IN WITNESS WHEREOF, this Agreement has been executed by an appropriate officer of Comerica Incorporated and by the Award Recipient, both as of the day and year first above written.
