events beyond the control of the Participant.

SECTION III - ELIGIBILITY

Each director of the Company, each director of any Subsidiary of the Company and
each director of an Advisory Board of a Subsidiary of the Company shall be
eligible to participate in the Plan provided any such director is not an
employee of the Company or an employee of any Subsidiary of the Company.

SECTION IV - PROCEDURES RELATING TO DEFERRALS

         A.    Deferral of Directors Compensation.

               1. Deferral for Directors of the Company. No more than one-half
of the Director Fees of each of the Company's directors shall be subject to a
Deferral Election (other than length of deferral and schedule of pay-out) under
this Plan. The remainder of the Directors' Fees of each Company director shall
be deferred automatically as provided in the Comerica Incorporated 1999 Common
Stock Director Fee Deferral Plan. The minimum period of deferral for Director
Fees deferred pursuant to this Section IV (A) shall be the lesser of the

                                      -2-

   5

number of years remaining before regular retirement or five years. In the event
a Company director does not indicate the period of deferral for such fees on the
Deferral Election, such fees shall be deferred for a period of five years and
paid out in a single lump sum.

               2. Deferral for Directors of any Subsidiary. Directors of any
Subsidiary of the Company may defer any portion of their compensation under this
Plan or the Comerica Incorporated 1999 Common Stock Director Fee Deferral Plan.
The minimum period of deferral for Director Fees deferred pursuant to this
Section IV (A) shall be the lesser of the number of years remaining before
regular retirement or five years. In the event a director of any Subsidiary of
the Company does not indicate the period of deferral, such fees shall be
deferred for a period of five years and paid out in a single lump sum.

               3. Deferral for Directors of any Advisory Board. Directors of an
Advisory Board of any Subsidiary of the Company may defer any portion of their
compensation under this Plan or the Comerica Incorporated 1999 Common Stock
Director Fee Deferral Plan. The minimum period of deferral for Director Fees
deferred pursuant to this Section IV (A) shall be the lesser of the number of
years remaining before regular retirement or five years. In the event a director
of an Advisory Board of any Subsidiary of the Company does not indicate the
period of deferral, such fees shall be deferred for a period of five years and
paid out in a single lump sum.

         B. Elective Deferral Procedures. Any eligible director wishing to defer
Director Fees which are subject to a Deferral Election must submit a Deferral
Election to the Corporate Secretary at 500 Woodward, MC 3391, Detroit, Michigan
48226-3391 or such other person designated by the Chief Executive Officer of the
Company from time to time, prior to the beginning of the service year during
which the fees are to be earned (from annual meeting of shareholders to annual
meeting of shareholders). However, any newly-appointed or newly-elected director
may submit a Deferral Election within sixty days of his or her appointment or
election. A Deferral Election pursuant to this Plan may cover all or a portion
of Director Fees which may be deferred pursuant to this Plan but shall not cover
amounts subject to an automatic allocation pursuant to the Comerica Incorporated
1999 Common Stock Director Fee Deferral Plan, and shall designate in which
mutual fund and in what proportions the Director Fees under this Plan so
deferred will be recorded.

        1.    Irrevocability. A director may not modify or revoke a Deferral
              Election (except to the extent permitted to reallocate among
              investment options), once the director has performed the services
              that entitle the director to the fees. If a director has submitted
              a Deferral Election relating to fees to be earned in the future,
              he or she may modify such election by submitting a new Deferral
              Election prior to the beginning of the calendar year in which the
              fees will be earned. Any such Deferral Election will supersede any
              previous Deferral Election as it relates to fees to be earned in
              future years.

        2.    Cancellation. A Deferral Election may be canceled by submitting a
              Cancellation of Deferral Election in form and substance as
              provided in Exhibit B attached hereto, as such form may be
              modified by the Plan Administrator from time to time. A director
              who cancels a Deferral Election may not submit a new Deferral
              Election


                                      -3-

   6


               before at least twelve months have elapsed from the effective
               date of the cancellation.

SECTION V - CREDITING OF EARNINGS TO ACCOUNTS

Director Fees which have been deferred under this Plan shall be credited to
Mutual Fund Unit Accounts created by and recorded on the books of the Company
from time to time. As of the last day of each month or on a more frequent basis
if practicable, each Mutual Fund Unit Account shall be adjusted as follows:


         A. Mutual Fund Unit Account shall be "hypothetically invested" in one
of the mutual funds offered for investment by the Committee and designated by
each director. In the event the sponsor of said mutual fund ("Sponsor") has
established a rabbi trust for its own benefit to fund the Sponsor's obligations
under this Plan, the purchase price for the mutual fund shares shall be the
actual price of the shares the Sponsor purchases on the open market on the day
of the deferral of the Director Fees. In the event that the Sponsor has not
established a rabbi trust, the purchase price shall be based upon the closing
price for the mutual fund shares on the exchange of which the mutual fund is
listed on the day that the Director Fees would have otherwise been paid to the
director had they not been deferred. No director shall have any right to vote
any shares of the Sponsor's mutual funds held in the rabbi trust except to the
extent otherwise permitted by the terms of the rabbi trust.

         1.    The account shall first be charged with any distributions made
               during the month or on a more frequent basis if practicable;

         2.    The account shall then be credited with earnings, gains and
               losses for the month based upon the closing price for the
               designated mutual fund on the exchange of which said fund is
               listed as of the last day of such month or on a more frequent
               basis if practicable, plus any dividends paid during such period.

         3.    The account shall then be credited with the amount, if any, of
               Director Fees deferred and designated to be credited to such
               account during such month or on a more frequent basis if
               practicable.

         B. Reallocation of Investment Options. Each director may reallocate all
or a portion of his or her Mutual Fund Unit Account to change the percentage(s)
of an investment and/or designate an alternate mutual fund as an investment
option by submitting a Reallocation Form in form and substance as provided in
Exhibit "C" to the Corporate Secretary or such other person designated by the
Chief Executive Officer of the Company from time to time. The Plan Administrator
may delay any reallocation request because of a trading blackout period or any
other trading restriction which may be imposed on the Company, whether voluntary
or involuntary. No transfers between investment options will be allowed if
prohibited by the rules applicable to the particular mutual fund from or to
which a transfer is to be made or by rules adopted by the Plan Administrator and
communicated to the directors.

SECTION VI - DISTRIBUTION OF DEFERRED FEES

         A. Time and Manner. Distribution of each Participant's account shall be
made in cash at such time and in such manner, i.e., a lump sum or installments,
as the Participant has specified in the Deferral Election(s) submitted to the
Corporate Secretary or as otherwise required by Section IV(A).

         B. Installment Payments. Installment payments under an installment
payment option may not exceed ten years. The amount of each installment payment
shall be determined by multiplying the balance of the Mutual Fund Unit Account
on the date the installment is scheduled to be paid by a fraction, the numerator
of which is one and the denominator of which is the number of unpaid
installments remaining at such time. If a Participant who is receiving
installment payments dies prior to receiving the balance of his or her account,
the unpaid balance shall be paid in one lump sum to the Participant's
Beneficiary(ies) not later than the 15th day of the month following the month in
which the Participant's death occurred.

         C. Hardship Distributions. In the event of an Unforeseeable Emergency
involving a Participant which occurs prior to distribution of the entire balance
of the Participant's Mutual Fund Unit Account, the Committee may, in its sole
discretion, distribute to the Participant in a single sum an amount equal to
such portion of such account as shall be necessary, in the judgment of the
Committee, to alleviate the financial hardship occasioned by the Unforeseeable
Emergency. Any Participant desiring a distribution under the Plan on account of
an Unforeseeable Emergency shall submit to the Committee a written request for
such distribution which sets forth in reasonable detail the Unforeseeable
Emergency which would cause the Participant severe financial hardship, and the
amount which the Participant believes to be necessary to alleviate the financial
hardship. In determining whether to grant any requested hardship distribution,
the Committee shall adhere to the requirements of Section 1.457-2(h)(4) of the
Income Tax Regulations (or to any successor regulations dealing with the same
subject matter), the provisions of which are incorporated herein by reference.

         D. Cash Out Distributions. If, at the time an installment distribution
of a Mutual Fund Unit Account in the name of any Participant is scheduled to
commence, the fair market value of such account does not exceed $10,000, then,
notwithstanding an election by the Participant that such account be distributed
in installments, the balance of such account shall be distributed to the
Participant in a single sum on or about the date the first installment is
scheduled to be made.

SECTION VII - DESIGNATION OF BENEFICIARY

Upon becoming a Participant of the Plan, each director shall submit to the
Corporate Secretary or such other person designated by the Chief Executive
Officer of the Company from time to time a Beneficiary Designation on the form
attached as Exhibit "D" designating one or more Beneficiaries to whom payments
otherwise due the Participant shall be made in the event of the Participant's
death before distribution of the Participant's Mutual Fund Unit Account has been
completed. A Beneficiary Designation will be effective only if it is signed by
the Participant and submitted to the Corporate Secretary before the
Participant's death.

                                       -5-

   8



Any Beneficiary Designation submitted to the Corporate Secretary will supersede
any previous Beneficiary Designation so submitted. If the primary beneficiary
shall predecease the Participant or the primary beneficiary and the Participant
die in a common disaster under such circumstances that it is impossible to
determine who survived the other, amounts remaining unpaid at the time of the
Participant's death shall be paid to the alternate beneficiary(ies) who survive
the Participant. If there are no alternate beneficiaries living or in existence
at the date of the Participant's death, the balance of the account shall be paid
in one lump sum to the legal representative of the Participant's estate.

SECTION VIII - MISCELLANEOUS PROVISIONS

         A. Nonalienation of Benefits. Neither the Participant nor any
Beneficiary designated by him or her shall have any right to alienate, assign,
or encumber any amount that is or may be payable hereunder, nor may any such
amount be subject to attachment, garnishment, levy, execution or other legal or
equitable process for the debts, contracts, liabilities, engagements or acts of
any Participant or Beneficiary.

         B. Administration of Plan. Full power and authority to construe,
interpret, and administer the Plan shall be vested in the Directors' Committee
of the Board of Directors of the Company. To the extent permitted by law, the
Committee may delegate any authority it possesses to the Plan Administrator. To
the extent the Committee has delegated authority concerning a matter to the Plan
Administrator, any reference in the Plan to the "Committee" insofar as it
pertains to such matter, shall refer likewise to the Plan Administrator.
Decisions of the Committee shall be final, conclusive, and binding upon all
parties.

         C. Amendment or Termination. The Board of Directors of the Company may
amend or terminate this Plan at any time. Any amendment or termination of this
Plan shall not affect the rights of Participants or Beneficiaries to the amounts
in the Mutual Fund Unit Account of such amendment or termination. The Plan
Administrator may make any amendments to the Plan, including forms under the
Plan, recommended by the Company's legal counsel which are necessary or
appropriate to keep the Plan and forms in compliance with applicable laws. The
Company reserves the right to accelerate distribution of fees deferred hereunder
in the event the Plan is terminated.

         D. Effective Date. This Plan is intended to constitute an amendment and
restatement of a prior plan maintained by the Company captioned "Comerica
Incorporated Director Fee Deferral Plan". The Plan was approved by the Board of
Directors of Company on May 21, 1999. The version of the Plan contained in this
document shall be effective to defer monies to be earned from and after January
1, 1997, and the earnings rate contained in this version of the Plan shall apply
to existing accounts under the Plan beginning January 1, 1997. Except for the
earnings rate, monies deferred under prior versions of the Plan shall remain
subject to prior deferral elections.

         E. Statements to Participants. Statements will be provided to
Participants under the Plan on at least an annual basis.


                                       -6-

   9



         F. Nonforfeitability of Participant Accounts. Each Participant shall be
fully vested in his or her Mutual Fund Unit Account created by Company from time
to time.

         G. Successors Bound. The contractual agreement between Comerica
Incorporated and each Participant resulting from the execution of a Deferral
Election shall be binding upon and inure to the benefit of Comerica
Incorporated, its successors and assigns, and to the Participant and to the
Participant's heirs, executors, administrators and other legal representatives.

         H. Governing Law and Rules of Construction. This Plan shall be governed
in all respects, whether as to construction, validity or otherwise, by
applicable federal law and, to the extent that federal law is inapplicable, by
the laws of the State of Michigan. Each provision of this Plan shall be treated
as severable, to the end that, if any one or more provisions shall be adjudged
or declared illegal, invalid or unenforceable, this Plan shall be interpreted,
and shall remain in full force and effect, as though such provision or
provisions had never been contained herein. It is the intention of Comerica
Incorporated that the Plan established hereunder be "unfunded" for income tax
purposes, whether or not the Company establishes a rabbi trust, and the
provisions hereof shall be construed in a manner to carry out that intention.

         I. Ownership of Fee Deferrals. Title to and beneficial ownership of any
assets, of whatever nature, which may be allocated by Comerica Incorporated to
any Mutual Fund Unit Account in the name of any Participant shall at all times
remain with Comerica Incorporated, and no Participant or Beneficiary shall have
any property interest whatsoever in any specific assets of Comerica Incorporated
by reason of the establishment of the Plan. The rights of each Participant and
Beneficiary hereunder shall be limited to enforcing the unfunded, unsecured
promise of Comerica Incorporated to pay benefits under the Plan, and the status
of any Participant or Beneficiary shall be that of an unsecured general creditor
of Comerica Incorporated.
