                              COMERICA INCORPORATED
                                NO SALE AGREEMENT

THIS AGREEMENT (the "Agreement") between Comerica Incorporated (the "Company")
and __________ (the "Award Recipient") is effective as of ________, 2___. Any
undefined terms appearing herein as defined terms shall have the same meaning as
they do in the Amended and Restated Comerica Incorporated Management Incentive
Plan (the "Plan"). The Company will provide a copy of the Plan to the Award
Recipient upon request.

1. SHARES. This Agreement applies to __________ shares of Company common stock,
par value $5.00 per share (the "Shares"), earned by the Award Recipient in
connection with that portion of a three-year Incentive Payment under the Plan
for the ____-____ Performance Period that is automatically invested in shares of
Company common stock.

2. RESTRICTIONS ON TRANSFER OF SHARES. Subject to Section 4 below, the Shares
will not be transferable during the period beginning on the date of grant and
ending upon the termination for any reason (including death, disability,
retirement, voluntary resignation or involuntary termination, whether or not for
"cause") of the Award Recipient's employment with the Company or any of its
Affiliates (the "No Sale Period"). The Shares will become immediately
transferable at the end of the No Sale Period. As soon as practical after
termination of the Award Recipient's employment or a Change of Control of the
Company, the Company will terminate the no sale restriction and, if the Award
Recipient so requests (or, if the Award Recipient is not then living and if his
or her designated beneficiary so requests), the Company will, at its option,
either: (a) deliver to the Award Recipient (or, if the Award Recipient is not
then living, to his or her designated beneficiary) a certificate that does not
contain any restrictive legends, evidencing his or her ownership of the Shares
(free of restrictions on transfer); or (b) make a book entry of such Shares
evidencing his or her ownership of the Shares free of restrictions on transfer.

3. NONTRANSFERABILITY. The Award Recipient may not sell, assign, transfer,
pledge or otherwise encumber the Shares, nor any of his or her rights
pertaining thereto, during the No Sale Period, other than by will or the laws
of intestacy.

4. EFFECT OF A CHANGE OF CONTROL. The No Sale Period will lapse as of the date
that a Change of Control, as defined in Section 6 of the Plan, occurs.

5. COMPLIANCE WITH LAWS AND REGULATIONS. The obligation of the Company to
deliver the Shares covered by this Agreement is subject to all applicable
federal and state laws, rules and regulations, to 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.

6. REINVESTMENT OF DIVIDENDS. During the No Sale Period, the Company will
reinvest cash dividends paid with respect to the Shares in additional shares of
common stock of the Company, and shares received pursuant to such reinvestment
will be subject to the same restrictions as the Shares. In addition, in the
event of a stock dividend, stock distribution, stock split, division of shares
or other corporate structure change which results in the issuance of additional
shares with respect to the Shares, such additional shares will be subject to the
same restrictions as the Shares.

7. BINDING NATURE OF THE PLAN. The Award Recipient agrees to be bound by all
terms and provisions of the Plan and related administrative rules and
procedures, including terms and

                                        1
<PAGE>

provisions and administrative rules and procedures adopted and/or modified after
the date of this Agreement. In the event any provisions hereof are inconsistent
with those of the Plan, the provisions of the Plan shall control.

8. NOTICES. Any notice to the Company under this Agreement shall be in writing
to the following address: Human Resources - Executive Compensation, Comerica
Incorporated, 500 Woodward Ave., MC 3122, Detroit, MI 48226. The Company will
address any notice to the Award Recipient to the Award Recipient's current
address according to the Company's personnel files. All written notices provided
in accordance with this paragraph shall be deemed to be given when (a) delivered
to the appropriate address by hand or by a nationally recognized overnight
courier service (costs prepaid); or (b) 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
for notice under this Agreement.

9. 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.

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

11. 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 for any given period or on any specified terms, nor in any way
affect the Company's right to terminate the Award Recipient's employment without
prior notice at any time for any reason or for no reason.

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

<PAGE>

Shares that may be purchased, or awarded as Service Award Contributions, under
the Plan shall be automatically adjusted, and the Committee shall be authorized
to make such other equitable adjustments as it deems necessary so that the value
of the interest of the Participants shall not be decreased by reason of the
occurrence of such event. Any such adjustment shall be deemed conclusive and
binding on the Corporation, each Participant, his or her Beneficiaries and all
other interested parties.

      D. Supplements. From time to time, supplements may be attached by
amendment to and form a part of this Plan and shall be given the same effect
that such provision would have if it was incorporated within the basic text of
the Plan. Such supplements may modify or supplement the provisions of the Plan
as they apply to particular groups of Employees or groups of Participants, shall
specify the persons affected by such supplements and shall supersede the other
provisions of the Plan to the extent necessary to eliminate inconsistencies
between the Plan provisions and the provisions of such supplements.

      E. Non-Resident Aliens. With respect to non-resident alien Employees, the
Committee or Plan Administrator may adopt one or more sets of procedures and
provisions, which may be different than those included in this Plan for other
Participants, with each set of procedures and provisions applying to some or all
of such non-resident alien Employees, as determined by the Committee in its sole
discretion or the Plan Administrator in his or her sole discretion, in order to
comply with the applicable laws of the respective jurisdiction(s) in which such
non-resident alien Employees live or work and/or to take into account other
legal, tax, accounting and similar issues arising by virtue of the participation
of such non-resident alien Employees. The adoption of any such procedures and
provisions shall not be deemed an amendment to this Plan.

      F. Applicable Law. To the extent not preempted by the laws of the United
States, the laws of the State of Delaware shall be the controlling law in all
matters relating to this Plan.

SECTION IV - PARTICIPATION

      A. Eligibility. Any person who is or becomes an Employee may commence
participation in the Plan as soon as administratively feasible on or subsequent
to such individual's date of hire; provided, however, that for purposes of the
Plan, the Committee or the Plan Administrator may exclude from eligibility
non-resident aliens (or classes of non-resident aliens), if any, if the
requirements of local law, rules or regulations, including without limitation,
the tax, labor, accounting or securities laws, rules, regulations or
consequences, make participation by such non-resident aliens (or class(es) of
non-resident aliens) impractical, as determined by the Committee in its sole
discretion or the Plan Administrator in his or her sole discretion.

determined by the Committee or the Plan Administrator, following the
Corporation's receipt of instructions to commence such contributions.

      C. Election Changes. A Participant may increase, decrease, cease or resume
the amount of his or her Payroll Withholding Contributions by communicating
further instructions pursuant to such procedures as are established by the
Committee or the Plan Administrator from time to time. Election changes shall
become effective as soon as administratively feasible after instructions have
been properly communicated. There shall be no limitation on the number of
election changes a Participant may make. A discontinuance of contributions in
and of itself shall not constitute a withdrawal from the Plan.

SECTION V - CONTRIBUTIONS

      A. Payroll Withholding Contributions. Any Payroll Withholding Contribution
shall equal at least 0.5% but not exceed 100% of a Participant's Bi-Weekly Base
Pay, net of all other applicable withholding and deductions. The Corporation
shall remit these contributions to the Custodian Bank promptly.

      B. Other Permitted Contributions. A Participant may make Other Permitted
Contributions in a single sum at such time or times permitted by the Committee
or the Plan Administrator.

      C. Matching Contributions. The Corporation shall make a Matching
Contribution equal to 15% of the Payroll Withholding Contributions, Service
Award Contributions and/or Other Permitted Contributions made by, or on behalf
of, each Participant during any calendar quarter, provided there have been no
withdrawals from the Participant's Account during such quarter. Matching
Contributions will not be made with respect to Share Retention Contributions. In
addition, Matching Contributions will not be made with respect to Payroll
Withholding Contributions, Service Award Contributions and/or Other Permitted
Contributions made during any Plan Year to the extent such contributions exceed
$25,000 in the aggregate. Matching Contributions will be made at or after the
end of each calendar quarter and shall be net of all applicable withholding and

with respect to a calendar quarter if there have been no withdrawals during such

      D. Share Retention Contributions. Subject to the conditions and
limitations of this Section V(D), the Corporation shall allocate Share Retention
Contributions to the Accounts of those Participants who qualify therefor.
Subject to the conditions and limitations of this Section V(D), a Participant
shall qualify for a Share Retention Contribution in a Plan Year if the
Participant is employed on the last day of the relevant Two-Plan-Year-Period,
and if, during such Two-Plan-Year-Period, there has not been a withdrawal of any
of the following:

      i. Payroll Withholding Contributions, Service Award Contributions or Other
      Permitted Contributions made during such period;

      ii. Matching Contributions made during such period;

      iii. Corporation Shares purchased with any contributions referred to in to
      Section V(D)(i) or (ii); or

      iv. Corporation Shares purchased with dividends paid with respect to any
      shares referred to in Section V(D)(iii).

      Share Retention Contributions will not be made with respect to Matching
Contributions. In addition, Share Retention Contributions will not be made with
respect to Payroll Withholding Contributions, Service Award Contributions and/or
Other Permitted Contributions made during any Plan Year to the extent such
contributions exceed $25,000 in the aggregate. Share Retention Contributions
shall be made as soon as reasonably practicable after the first day of the Plan
Year following a Two-Plan-Year-Period and shall be net of all applicable
withholding and deductions.

      Notwithstanding anything in this Section V(D) to the contrary, a
Participant whose employment terminates by reason of Retirement, death or
Disability prior to the end of a Two-Plan-Year-Period shall be eligible to
receive a Share Retention Contribution with respect to such partial
Two-Plan-Year-Period (consisting of the Plan Year during which the Participant's
employment so terminates and the immediately preceding Plan Year) if and only if
there have been no withdrawals during such period (prior to termination of
employment). The Share Retention Contribution made on behalf of any such
eligible terminated Participant with respect to such period shall be prorated
based on the number of days during the final Plan Year that the Participant was
employed.

      For purposes of this Section V(D), a Participant's employment shall be
considered to have terminated by reason of Retirement if he or she terminates
employment with eligibility for, and elects to commence receipt of, an early or
normal retirement benefit under a tax-qualified defined benefit retirement plan
maintained by the Corporation, and a Participant's employment shall be
considered to have terminated by reason of Disability if he or she terminates
employment with eligibility for,

                                       7

16 Insider under Section 16 of the Exchange Act) either (i) acquired Corporation
Shares in the open market or pursuant to a private transaction; or (ii) made an
election under the Plan (or under any other Plan sponsored by the Corporation)
that resulted in an acquisition of equity securities of the Corporation within
the meaning of that term under Section 16 of the Exchange Act. The Committee or
Plan Administrator may make such other rules as are necessary to comply with
Section 16 of the Exchange Act, as amended from time to time.

Designation Form designating one or more Beneficiaries to whom the balance of
the Participant's Account is to be distributed in the event assets remain in
such Account at the time of the Participant's death, or by whom any rights of
the Participant, after the Participant's death, may be exercised. A Beneficiary
Designation Form will be effective only if it is signed by the Participant and

Form properly submitted will supersede any previous Beneficiary Designation Form
so submitted. If a Participant designates a spouse as a Beneficiary, such

balance of the Participant's Account shall be distributed to the alternate
Beneficiary(ies) who survive(s) the Participant in accordance with this Plan. If
there are no alternate Beneficiaries living or in existence at the date of the
Participant's death, or if the Participant has not submitted a valid Beneficiary
Designation Form to the Corporation, the balance of the Participant's Account
shall be distributed in accordance with the terms of the Plan to the legal
representative for the benefit of the Participant's estate.

      The Corporation reserves the right to distribute the balance of a
Participant's Account to his or her estate notwithstanding the designation of a
Beneficiary, if the Corporation is unable to locate the Beneficiary, a dispute
arises among Beneficiaries or under any other circumstances the Corporation
deems appropriate.

      B. Withholding of Taxes. The Corporation shall withhold from any amounts
payable to the Participant all Federal, state, city, or other taxes and/or other

all applicable laws in operating this Plan and shall administer and interpret
this Plan in accordance with legal requirements.
