                              1998 PROXY STATEMENT
 
                             QUESTIONS AND ANSWERS
 
WHAT IS A PROXY?
 
A: A proxy is a document, also referred to as a proxy card (which is enclosed),
by which you authorize someone else to vote for you in the way that you want to
vote. Comerica's Board of Directors is soliciting this proxy. You may also
abstain from voting if you so choose.
 
WHAT IS A PROXY STATEMENT?
 
A: A proxy statement is the document the United States Securities and Exchange
Commission (the "SEC") requires to explain the matters on which you are asked to
vote on the proxy card.
 
WHO CAN VOTE?
 
A: Only holders of shares of Comerica's common stock at the close of business on
March 23, 1998 can vote at the Annual Meeting. Each shareholder of record has
one vote for each share of common stock on each matter presented for a vote at
the meeting.
 
WHAT WILL I VOTE ON AT THE MEETING?
 
A: At the Annual Meeting, shareholders will vote to:
 
   1. Elect four Class II Directors for three year terms expiring in 2001 or
      upon the election and qualification of their successors.
 
   2. Approve an amendment to Comerica's Certificate of Incorporation to
      increase the number of shares of common stock which Comerica is authorized
      to issue from 250,000,000 to 325,000,000.
 
   3. Transact any other business that is properly submitted before the Annual
      Meeting or any adjournments of the meeting.
 
HOW DOES THE RECENT STOCK SPLIT AFFECT THIS PROXY STATEMENT?
 
A:  On January 15, 1998, Comerica's Board of Directors declared a three-for-two
stock split, payable in the form of a 50% stock dividend on April 1, 1998 (the
"Payment Date") to shareholders of record on March 15, 1998. The Record Date for
the Annual Meeting is before the Payment Date; therefore each shareholder will
vote a pre-split number of shares at the Annual Meeting. Accordingly, Comerica
has not adjusted the numerical information relating to shares of Comerica's
common stock in this Proxy Statement to reflect the stock split.
 
HOW CAN I VOTE?
 
A:  You can vote in person, by telephone or by proxy. To vote by proxy, sign,
date and return the enclosed proxy card. To vote by using the automated
telephone voting system, you must hold your shares in your name, and not in the
name of a broker, dealer, bank or other third party, and you should follow the
instructions on the enclosed proxy card. If you returned your signed proxy card
to Comerica before the Annual Meeting, the persons named as proxies on the card
<PAGE>   7
 
will vote your shares as you directed. You may revoke a proxy at any time before
the proxy is exercised by (1) giving written notice of revocation to the
Corporate Secretary of Comerica at the address listed in the third paragraph of
the Notice of Annual Meeting of Shareholders; (2) submitting another proxy that
is properly signed and later dated; (3) voting in person at the meeting (but
only if the shares are registered in Comerica's records in the name of the
shareholder and not in the name of a broker, dealer, bank or other third party);
or (4) if you previously voted by telephone, voting by telephone at a subsequent
time.
 
IS MY VOTE CONFIDENTIAL?
 
A:  Yes, your vote is confidential. Only the inspectors of election and certain
employees associated with processing proxy cards and counting the vote have
access to your proxy card. All comments you direct to management (whether
written on the proxy card or elsewhere) will remain confidential unless you ask
that your name be disclosed.
 
WHAT IS A QUORUM?
 
A:  There were 104,838,086 shares of Comerica's common stock outstanding on the
Record Date. A majority of the outstanding shares, or 52,419,044 shares, present
or represented by proxy, constitutes a quorum. A quorum must exist to conduct
business at the Annual Meeting.
 
HOW DOES VOTING WORK?
 
A:  If a quorum exists, each director and the amendment to the Certificate of
Incorporation must receive the favorable vote of a majority of the shares voted,
excluding abstentions and broker non-votes. A broker non-vote is a proxy a
broker submits that does not indicate a vote for some or all the proposals
because the broker does not have discretionary voting authority and the broker
did not receive instructions as to how to vote on those proposals.
 
Comerica will vote properly executed proxies it receives prior to the meeting in
the way you have directed. If you do not specify instructions, the shares
represented by proxies will be voted to elect the nominees for Class II
Directors and to approve the amendment to Comerica's Certificate of
Incorporation. No other proposals are currently scheduled to be presented at the
meeting.
 
An independent third party acts as the inspector of the meeting and the
tabulator of votes.
 
WHO PAYS FOR THE COSTS OF THE MEETING?
 
A:  Comerica pays the cost of preparing and printing the Proxy Statement and
soliciting proxies. Comerica will solicit proxies primarily by mail, but may
also solicit proxies personally and by telephone, facsimile or other means.
Comerica will use the services of Georgeson & Company, Inc., a proxy
solicitation firm, at a cost of $9,000 plus out-of-pocket expenses and fees for
any special services. Officers and regular employees of Comerica and its
subsidiaries may also solicit proxies, but will receive no additional
compensation for soliciting proxies, nor will their efforts result in more than
a minimal cost to Comerica. Comerica also will reimburse banks, brokerage houses
and other custodians, nominees and fiduciaries for their out-of-pocket expenses
for forwarding solicitation material to beneficial owners of Comerica's common
stock.
 
WHAT PERCENTAGE OF STOCK DO OFFICERS AND DIRECTORS OWN?
 
A:  Together, executive officers, directors and director nominees owned
approximately 3.3% of Comerica's common stock as of the Record Date.

                   THE TWO PROPOSALS ON WHICH YOU ARE VOTING:
 
PROPOSAL 1:  ELECTION OF DIRECTORS
 
Comerica's Board of Directors is divided into three classes with each class of
directors elected to a three-year term of office. At each annual meeting of
shareholders, shareholders elect one class of directors for a three-year term to
succeed the class of directors whose term of office expires at that meeting.
This year you are voting on four candidates for the Class II Directors. Based on
the recommendation of the Directors Committee, Comerica's Board of Directors has
nominated James F. Cordes, Eugene A. Miller, Martin D. Walker and Kenneth L.
Way. Messrs. Cordes and Miller currently serve as Class II directors, Mr. Walker
is currently a Class III director and Mr. Way is a director of Comerica Bank, a
subsidiary of Comerica. If the shareholders elect Mr. Walker as a Class II
director, the Board of Directors, will fill the vacancy created in Class III by
his election, in accordance with Comerica's bylaws and upon the conclusion of
its current search for an additional director. Class III directors will stand
for re-election next year. Each of the nominees has consented to his or her
nomination and has agreed to serve as a director of Comerica, if elected.
 
If any director is unable to stand for re-election, Comerica may vote the shares
to elect any substitute nominees recommended by the Directors Committee. If the
Directors Committee does not recommend any substitute nominees, the number of
directors to be elected at the Annual Meeting may be reduced by the number of
nominees who are unable to serve.
 
For more information on Comerica's Board of Directors and these nominees, please
refer to pages 4 and 5 of this Proxy Statement.
 
Comerica's Board of Directors recommends a vote FOR these directors.
 
PROPOSAL 2:  PROPOSAL TO AMEND COMERICA'S CERTIFICATE OF INCORPORATION
 
OVERVIEW:  On January 20, 1998, the Board of Directors approved a proposal to
amend Comerica's Certificate of Incorporation to increase the number of shares
of common stock which Comerica is authorized to issue from 250,000,000 to
325,000,000. If adopted, Comerica will file the amendment on the next business
day after the Annual Meeting.
 
Appendix A to this Proxy Statement contains the text of the proposed amendment
to the Certificate of Incorporation. The amendment will not affect the number of
authorized shares of preferred stock, which is 10,000,000 shares.
 
REASON FOR INCREASE IN NUMBER OF AUTHORIZED SHARES:  Comerica requires the
increase in authorized shares of common stock to enable Comerica to maintain a
number of shares sufficient to meet all anticipated requirements, such as the
issuance of shares in a stock split in the future and to provide flexibility for
other corporate purposes.
 
The proposed amendment would increase the number of shares of common stock which
Comerica is authorized to issue from 250,000,000 to 325,000,000. The additional
75,000,000 shares would be a part of the existing class of common stock and, if
and when issued, would have the same rights and privileges as the shares of
common stock presently issued and outstanding. Each shareholder of Comerica
common stock has the right to acquire Series D Participating Preferred Stock
("Rights") in the event of the occurrence of certain triggering events described
in the Rights Plan. The holders of common stock of Comerica are not entitled to
preemptive rights or cumulative voting.
 
The Board of Directors recommends a vote FOR this proposal.

  *The Executive Committee is comprised of these three executive officers and a
   minimum of any four non-employee directors who are available at the time it
   is necessary for the Executive Committee to act.
 
 **Chairperson
 
***Dr. Longe and Mr. MacDonald are incumbent Class II directors whose terms will
   expire at the Annual Meeting.
 
EXECUTIVE COMMITTEE.  This committee can exercise the authority, powers and
duties of the Board of Directors in managing the business and affairs of
Comerica between meetings of the board, if necessary. In the event that the
committee convenes, the committee's members are the three executive officers
identified in the chart and a minimum of any four non-employee directors who are
available at that time. The Executive Committee did not meet during 1997 because
it was not necessary. The Board of Directors or other appropriate committees
managed Comerica's business and affairs during 1997.
 
AUDIT AND LEGAL COMMITTEE.  This committee includes members with banking or
related financial management expertise and does not include directors who are
considered large customers of Comerica or any affiliate. The committee is
responsible for review and recommendation of Comerica's Audit Policy and Code of
Ethics, Comerica's significant litigation, the scope and procedures of
Comerica's internal and external audit process, the selection and performance
review of Comerica's independent auditors, the review of programs and procedures
designed to avoid conflicts of interest and to promote compliance with laws,
regulations and corporate policy and the investigations of any suspected
improprieties. The Audit and Legal Committee met four times during 1997.
 
COMPENSATION COMMITTEE.  This committee establishes Comerica's executive
compensation policies and programs, administers Comerica's 401k, stock,
incentive and deferral plans and monitors compliance with laws and regulations
applicable to the documentation and administration of Comerica's employee
benefit plans. The Compensation Committee met three times during 1997.
 
DIRECTORS COMMITTEE.  This committee monitors the effectiveness of the Board of
Directors. Among its various duties, the committee reviews and recommends board
members, develops and administers performance criteria for members of the board,
and establishes the size of the
                                        6
<PAGE>   12
 
board, its committee structure and assignments, and the conduct and frequency of
board meetings. The committee also administers Comerica's Stock Option Plan for
Non-Employee Directors (excluding the provisions for discretionary grants under
the plan) and Comerica's Stock Option Plan for Non-Employee Directors of
Comerica Bank and Affiliated Banks. The Directors Committee met once during
1997.
 
RISK ASSET QUALITY REVIEW COMMITTEE.  This committee reviews Comerica's credit
policies and promotes the use of sound operating procedures for credit
administration throughout the various affiliates of Comerica. Among its various
duties, the committee reviews Comerica's credit quality statistics and reserve
levels, and annually approves financial policies. The Risk Asset Quality Review
Committee met three times during 1997.
 
BOARD AND COMMITTEE MEETINGS.  There were six regular meetings, and one special
meeting, of the Board of Directors and eleven meetings of the various committees
of the board during 1997. All director nominees and incumbent directors who are
standing for re-election attended at least seventy-five percent of the aggregate
number of meetings held by the Board of Directors and by all the committees of
the board on which the respective directors served.
 
                       COMPENSATION COMMITTEE INTERLOCKS
                           AND INSIDER PARTICIPATION
 
No member of the Compensation Committee was a former officer or a current
officer or employee of Comerica or any of its subsidiaries. There were no
compensation committee interlocks between Comerica and any other entity during
the fiscal year.
 
                           COMPENSATION OF DIRECTORS
 
FEES.  Directors who are employees of Comerica do not receive additional
compensation for their service on the Board of Directors and its committees.
During 1997, non-employee directors received an annual retainer of $20,000 and
$1,000 each time a director attended a meeting of the Board of Directors. Each
non-employee director who served on a committee of the board also received
$1,000 each time such director attended a committee meeting. The chairman of
each committee received an additional annual retainer of $4,000. Comerica also
reimburses directors for all expenses incurred for the purpose of attending
board and committee meetings.
 
STOCK OPTION PLAN.  Comerica has a stock option plan for non-employee directors.
On the date of each annual meeting of shareholders, each non-employee director
receives an option to purchase 1,000 shares of common stock of Comerica. The
exercise price of each option is the fair market value of each share of common
stock on the date the option is granted. Options are exercisable one year after
the date of the grant and expire ten years after the grant date.
 
INSURANCE.  Comerica provides a $150,000 business travel, accidental death and
dismemberment insurance benefit for each non-employee director and maintains
directors' and officers' liability insurance policies with a primary limit of
$20 million and excess limits of $20 million each. The primary limit policy is
insured through the Financial Institution Risk Retention Group. The Federal
Insurance Company (a member of the Chubb Group) and Executive Risk are the
primary insurers for the excess limit policies.

<PAGE>   13
 
                         RETIREMENT PLAN FOR DIRECTORS
 
Comerica has a retirement plan for non-employee directors who have served at
least five years on the Board of Directors. For the purpose of determining
retirement income, each director receives credit for service on the Board of
Directors of Comerica and Manufacturers National Corporation.
 
Benefits become payable when the director reaches age 65 or retires from the
board, whichever occurs later. Payments may commence prior to the director's
65th birthday if he or she retires from the board due to illness or disability.
 
Under the plan, Comerica accrues, on behalf of each eligible director, one month
of retirement income credit for each month of service up to a maximum of one
hundred twenty months. Upon retirement, an eligible director receives a monthly
retirement benefit equal to one-twelfth of the annual retainer fee in effect for
directors on the date of such director's retirement. The eligible director
receives retirement benefits for the total number of months the director has
accrued retirement income credit, but payments terminate upon the director's
death.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
Section 16(a) of the Securities Exchange Act of 1934, as amended, requires that
Comerica's directors, executive officers and persons who own more than ten
percent of a registered class of Comerica's equity securities file reports of
stock ownership and any subsequent changes in stock ownership with the SEC and
the New York Stock Exchange not later than specified deadlines. During 1997, all
of the required reports were filed by the specified deadlines. In making this
disclosure, Comerica relied on the directors and executive officers' written
representations and a review of copies of the reports filed with the SEC.
 
                         TRANSACTIONS OF DIRECTORS AND
                        EXECUTIVE OFFICERS WITH COMERICA
 
Several of the incumbent directors, director nominees and executive officers of
Comerica, their related entities and members of their immediate families were
customers of and had transactions (including loans and loan commitments) with
banking affiliates of Comerica during 1997. Comerica made all loans and
commitments in the ordinary course of business, on substantially the same terms
(including interest rates and collateral) as those prevailing at the time for
comparable transactions with other persons not affiliated with Comerica or its
subsidiaries, and the transactions did not involve more than the normal risk of
collection or present other unfavorable features. All loan transactions
presently in effect with any incumbent director, nominee, executive officer or
related entity are current as of the date of this Proxy Statement.

(1) As of December 31, 1997, each of the named executive officers held the
    following number of shares of common stock ("restricted stock"), which the
    named executive officer will forfeit if he does not remain an employee for
    the term established by Comerica : Michael T. Monahan, 15,000 shares with a
    market value of $1,353,750; John D. Lewis, 10,000 shares with a market value
    of $902,500; Ralph W. Babb, Jr., 10,000 shares with a market value of
    $902,500; and Fenton R. Talbott, 10,000 shares with a market value of
    $902,500. Comerica calculated the market value using the closing price of
    Comerica's common stock of $90.25 per share on December 31,1997. The market
    value does not give effect to the diminution in value due to the
    restrictions on this stock.
 
(2) Comerica pays dividends on restricted stock at the same rate and on the same
    terms that it pays dividends on its common stock.
 
(3) Options granted under Comerica's option plans generally have a ten-year term
    and become exercisable annually in 25% increments, beginning on the first
    anniversary of the date of the option grant, except as determined otherwise
    by the Compensation Committee. The options granted to Mr. Babb in 1995
    became exercisable annually in 25% increments beginning in June 1996, except
    that they will be exercisable immediately if Mr. Babb dies or becomes
    permanently disabled, or upon a change of control of Comerica, or if
    Comerica terminates Mr. Babb's employment without cause or if he resigns for
    good reason. Comerica has never granted stock appreciation rights under the
    Long-Term Incentive Plan.
 
(4) Amounts in this column represent incentive awards based on Comerica's
    average return on equity performance for a three-year period from 1995
    through 1997. Comerica pays fifty percent of the award to each of the named
    executive officers in cash and fifty percent of the award in shares of
    common stock which may not be transferred by the executive officer until the
    executive's employment with Comerica terminates ("non-transferable stock").
    On March 20, 1998, each of the named executive officers received shares of
    non-transferrable stock pursuant to their 1997 incentive awards: Eugene A.
    Miller, 1,306.8601 shares; Michael T. Monahan, 962.9086 shares; John D.
    Lewis, 747.1487 shares; Ralph W. Babb Jr., 516.9692 shares; and Fenton R.
    Talbott, 384.5226 shares. Comerica calculated the number of shares to be
    awarded using a market price of $107.1270 on that date.
 
(5) Amounts for 1997 for each of the named executive officers include an $800
    matching contribution and a $2,938 performance match under Comerica's 401(k)
    plan. Amounts for 1997 also include life insurance premiums paid by Comerica
    for the benefit of the named executive officers: (Eugene A. Miller, $24,761;
    Michael T. Monahan, $13,570; John D. Lewis, $9,801; and Ralph W. Babb Jr.,
    $7,259).

(6) Amounts for 1997 for each of the named executive officers include an
    Employee Stock Purchase Plan matching contribution for the following named
    executive officers in the amount set forth opposite such officer's name:
    (Eugene A. Miller, $3,750; Ralph W. Babb Jr., $3,750; and Fenton R. Talbott,
    $3,635). All participants in the Employee Stock Purchase Plan are eligible
    to receive matching contributions. Amounts for 1997 for each of the named
    executive officers include a contribution under Comerica's Gainsharing Plan
    for the following named executive officers in the amount set forth opposite
    such officer's name: (Eugene A. Miller, $1,157; Michael T. Monahan $1,157;
    John D. Lewis, $1,157; Ralph W. Babb Jr., $1,157; and Fenton R. Talbott,
    $1,157). All persons who were employed by Comerica as of the date set forth
    in the plan received Gainsharing Plan contributions.

named executive officers.

(1) Participants earn long-term awards under the Management Incentive Plan based
    upon Comerica's attainment of specified objectives established by the
    Compensation Committee in relation to Comerica's average return on equity
    during the three year performance period. Comerica pays fifty percent of the
    awards in cash and fifty percent in shares of Comerica's non-transferable
    stock.
 
(2) Each year Comerica determines the amount necessary to fund long-term awards
    under the Management Incentive Plan for the upcoming year. The maximum
    stated for each named executive officer represents the funded amount
    allocable to the aggregate annual incentive pool based on such executive
    officer's organizational level and base salary. Actual payments to the named
    executive officer are a function of the amount of the annual incentive
    received by such executive officer in each of the three performance years
    occurring during the performance period as a percentage of the aggregate
    annual incentive pool paid in those three years to all participants in the
    Management Incentive Plan. As a result, an individual's awards may exceed or
    be less than the maximum funding allocable to that executive officer (as
    stated in the table above). In no case will the long-term award, when
    combined with the annual incentive, exceed 200% of the executive officer's
    base salary.
 
                     DEFINED BENEFIT PENSION PLAN BENEFITS
 
Comerica maintains the Comerica Incorporated Retirement Plan (1994 Amendment and
Restatement), a tax-qualified defined benefit pension plan (the "Pension Plan").
The Pension Plan is a consolidation of the former Manufacturers National
Corporation Pension Plan (the "Manufacturers Plan") and the Comerica
Incorporated Retirement Plan (the "Comerica Plan"). Participants who retire
under the Pension Plan receive a pension based on a formula which takes into
consideration final average compensation (which includes salary and regular
bonuses) and years of service, including years of service credited under the
Manufacturers Plan and Comerica Plan to the former participants of these plans.
 
The Pension Plan is a tax-qualified plan. Under the Internal Revenue Code of
1986, as amended (the "Internal Revenue Code"), the current maximum annual
pension that any participant, including any named executive officer, may receive
under a qualified defined benefit plan is $130,000. The maximum annual
compensation of any participant which Comerica currently can consider in
computing a pension under a qualified plan is $160,000. To the extent that
Tables I, II and III reflect an annual pension greater than $130,000 or
compensation above $160,000, Comerica will pay the participant, including any
named executive officer, the additional amount under a non-qualified plan
maintained by Comerica.

</TABLE>
 
Comerica computed annual pensions under the Pension Plan using base salary and
bonuses for the year earned as reflected on page 14 in the Summary Compensation
Table.
 
The estimated years of service credited under the Pension Plan for each of the
named executive officers as of April 10, 1998 are as follows: Eugene A. Miller,
35 years; Michael T. Monahan, 35 years; John D. Lewis, 27.5 years; Ralph W. Babb
Jr., 1.5 years and Fenton R. Talbott, 1 year. The years of service credited to
Messrs. Miller and Lewis include the following years of service credited under
the Comerica Plan for which a past service pension is payable under the Pension
Plan: Mr. Miller, 35 years; and Mr. Lewis, 23.5 years. The years of service
credited to Mr. Monahan include 32.5 years of service credited under the
Manufacturers Plan for which a past service pension is payable under the Pension
Plan.
 
Under the Pension Plan, a participant who is unmarried at the time he or she
retires generally receives a pension in the form of a straight life annuity, the
annual amounts of which are listed in the tables above. A participant who is
married at the time he or she retires generally receives a pension in the form
of a joint and 50% survivor annuity, the amount of which is actuarially
equivalent to the straight life annuity. The pension amounts appearing in the
Pension Plan Tables I, II and III above assume that retirement will occur at age
65.
 
                 EMPLOYMENT CONTRACTS AND SEVERANCE AGREEMENTS
 
EUGENE A. MILLER is a party to an employment agreement with Comerica.(1) The
agreement provides that Mr. Miller will serve as Chairman of the Board and Chief
Executive Officer of Comerica through June 30, 1999. On July 1, 1999, the term
of the agreement will be extended automatically every two years until Mr.
Miller's 65th birthday unless a majority of the directors of Comerica vote
against an extension. For the duration of the agreement, Comerica has agreed to
nominate Mr. Miller to serve on its Board of Directors.
 
During the term of his employment agreement, Comerica pays Mr. Miller a base
salary and annual bonus payments in amounts determined by the Compensation
Committee as
 
- ---------------
 
1The change of control agreement, described below, supersedes this agreement if
there is a change of control as defined in the change of control agreement.
                                       18
<PAGE>   24
 
commensurate with his position and performance. He also is eligible for option
grants and restricted stock awards under Comerica's Long-Term Incentive Plan.
These grants and awards also will be commensurate with his position and
performance. In addition, Mr. Miller also is eligible to participate in all of
Comerica's executive compensation plans for senior executives which are in
effect during the term of the employment agreement and in any employee benefit
plans which Comerica maintains.
 
If Comerica terminates Mr. Miller's employment without cause, or if Mr. Miller
resigns for good reason, or Comerica causes Mr. Miller's employment agreement to
expire prior to his 65th birthday, Mr. Miller will receive the following
principal benefits:
 
     - three times his annual base salary plus amount equal to his average
      annual bonus during the three year period prior to the termination of his
      employment, which will be paid in quarterly installments over a three year
      period;
 
     - accelerated vesting of any unexercised stock options;
 
     - the early lapse of restrictions on previously awarded shares of
      restricted stock;
 
     - continuation of health and accident insurance coverages for Mr. Miller
      and his wife for their lifetimes unless Mr. Miller receives comparable
      coverages from another source;
 
     - continuation of his life insurance coverage for three years; and
 
     - commencing at the end of the three-year payment period referred to above,
      a payment in the form elected by Mr. Miller under Comerica's defined
      benefit pension plan and excess benefit plan, in an amount equal to the
      excess of (a) the retirement benefits Mr. Miller would receive under the
      plans if he continued to receive service credit until his 65th birthday,
      over (b) the retirement benefits he actually accrued under the plans.
 
If Mr. Miller's employment is terminated less than three years before his 65th
birthday, Comerica will pro-rate the amount payable in connection with his
salary for the time period remaining until he reaches age 65. If Mr. Miller's
employment terminates for any of the reasons referred to above, the employment
agreement also provides that Comerica will use its best efforts, subject to the
fiduciary duties of the Board of Directors, to nominate Mr. Miller as a director
for the remainder of his life or until he reaches the mandatory retirement age
for members of the board.
 
If Mr. Miller retires, resigns without a good reason or if his employment
terminates because of disability or death or if Comerica terminates Mr. Miller's
employment for cause, Mr. Miller will receive his annual base salary to the date
of termination, fringe benefits and life, health, disability and accident
insurance to the date of termination.
 
If any payment to Mr. Miller under the employment agreement is subject to an
excise tax under Section 4999 of the Internal Revenue Code, Mr. Miller will
receive an additional payment so that the amount he receives equals the amount
he would receive under the agreement if an excise tax was not imposed.
 
MICHAEL T. MONAHAN participated in the Manufacturers National Corporation Key
Employee Retention Plan which Comerica assumed when it merged with Manufacturers
National Corporation. Mr. Monahan would have been eligible to receive severance
benefits under the plan if he retired prior to July 1, 1995. To encourage him to
remain with Comerica, Comerica entered into an agreement with Mr. Monahan which
provides certain benefits in lieu of the benefits he may have been eligible to
receive under the retention plan if he had retired on July 1, 1995. The
agreement provides that Mr. Monahan, or his beneficiary, is entitled to receive
the following benefits if he retires, dies or becomes disabled, or Comerica
involuntarily terminates his
 
                                       19
<PAGE>   25
 
employment with Comerica before February 1, 1999, or if his employment with
Comerica terminates for any reason on February 1, 1999:
 
     - a cash payment of $3,000,000;
 
     - continuation of his life, disability, accident and health insurance
      benefits for three years after his employment terminates, unless he
      becomes eligible to receive similar benefits from another employer during
      the three year period;
 
     - medical benefits for life; and
 
     - except in the case of a voluntary retirement before February 1, 1999, the
      accelerated vesting of all non-vested stock options held on the date of
      termination and the early lapse of any remaining restrictions on
      previously awarded shares of restricted stock.
 
RALPH W. BABB JR. is a party to an employment agreement with Comerica. The
agreement has a three-year term which expires on June 1, 1998. During the term
of his employment agreement, Comerica pays Mr. Babb a minimum annual base salary
of $300,000. Mr. Babb is also eligible for bonuses under Comerica's annual bonus
program. The agreement also provides a supplemental pension for Mr. Babb and his
wife if he remains with Comerica until June 1, 2000, or upon a change of control
of Comerica, or if Comerica terminates Mr. Babb's employment without cause or if
he resigns for good reason during the term of the agreement.
 
Upon entering into the employment agreement, Mr. Babb received a $100,000
signing bonus and an option to purchase 15,000 shares of Comerica's common
stock. He also received 10,000 shares of restricted common stock. The
restrictions on these shares cease if Mr. Babb remains employed with Comerica
until June 1, 2000. Restrictions relating to these shares will also cease prior
to that date if Mr. Babb dies or becomes permanently disabled, or upon a change
of control of Comerica, or if Comerica terminates Mr. Babb's employment without
cause or if he resigns for good reason.
 
Mr. Babb also is a party to a severance agreement with Comerica. The agreement
continues through May 31, 1998 and provides that Mr. Babb is entitled to receive
severance benefits if Comerica terminates his employment without cause or if he
resigns for good reason during the term of the agreement after a change of
control of Comerica. If Mr. Babb becomes entitled to receive severance benefits
under the agreement, he can receive in addition to other benefits: (1) an amount
equal to three times his annual base salary; (2) an amount equal to three times
the highest annual bonus he received previously; and (3) continuation of certain
benefits for three years. If any payment to Mr. Babb under the agreement is
subject to an excise tax under Section 4999 of the Internal Revenue Code, Mr.
Babb will receive an additional payment so that the amount he receives equals
the amount he would receive under the agreement if an excise tax was not
imposed. If an event occurs that could trigger a similar payment under both the
severance agreement and Mr. Babb's employment agreement, Mr. Babb will be
entitled to a payment under only one of the agreements.
 
                          CHANGE OF CONTROL AGREEMENTS
 
Each of Messrs. Miller, Lewis and Talbott is a party to a change of control
employment agreement with Comerica. These agreements become effective only in
the event of a change of control as defined in the agreement.
 
The agreement is for an initial three-year period (the "Agreement Period")
commencing on the date the named executive officer and Comerica sign the
agreement and is extended automatically at the end of each year for an
additional one year unless Comerica delivers written notice to such named
executive officer, at least sixty days prior to the annual renewal date, that
his agreement will not be extended. Comerica intends that the Agreement Period
will always be three years.
 
                                       20
<PAGE>   26
 
If a change of control of Comerica occurs during the Agreement Period, the
employment period begins and Comerica will continue the named executive
officer's employment for a period of thirty months from the date of the change
of control. During this employment period:
 
     - The named executive officer's position and duties will be at least
      commensurate with the most significant duties held by him during the
      120-day period prior the date of a change of control.
 
     - Comerica will assign the named executive officer an office at the
      location where he was employed on the date the change of control occurred
      or an office less than 60 miles from such office.
 
     - Each named executive officer will receive a monthly base salary equal to
      or greater than the highest monthly base salary he earned from Comerica
      during the twelve-month period prior to the date of the change of control,
      and an annual cash bonus at least equal to the highest bonus he earned
      during any of the last three fiscal years prior to the date the change of
      control occurred. (Comerica will annualize the amount of the bonus earned
      by the named executive officer during any of these years if such named
      executive officer was not employed by Comerica for the entire three-year
      period.)
 
     - The named executive officer also will be eligible to receive annual
      salary increases and to participate in all of Comerica's executive
      compensation plans and employee benefit plans, including health, accident,
      disability and life insurance benefit plans, at least equal to the most
      favorable of those plans which were in effect at any time during the
      120-day period preceding the effective date of his agreement.
 
If the named executive officer dies or becomes disabled during the employment
period, he or his beneficiary will receive accrued obligations, including
salary, pro rata bonus, deferred compensation and vacation pay, and death or
disability benefits.
 
The agreement also provides severance benefits to the named executive officer if
Comerica terminates his employment for any reason other than cause or
disability, or he resigns for good reason during the employment period. Good
reason under the agreement includes termination of the agreement by the named
executive officer for any reason during the 30-day period immediately following
the first anniversary of the change of control. If the named executive officer
becomes entitled to receive severance benefits under his agreement, he will
receive in addition to other benefits:
 
     - any unpaid base salary through the date of termination;
 
     - a proportionate bonus based upon the highest annual bonus he earned
      during any of the last three fiscal years prior to the effective date of
      his agreement or during the most recently completed fiscal year;
 
     - an amount equal to three times his annual base salary;
 
     - an amount equal to three times the highest annual bonus he earned during
      any of the last three fiscal years prior to the effective date of his
      agreement or during the most recently completed fiscal year;
 
     - payment under Comerica's defined benefit pension plan and any excess
      benefit plan in which he participates, in an amount equal to the excess
      of: (a) the retirement benefits he would receive under the plans if he
      continued to receive service credit for three years after the date his
      employment was terminated, over (b) the retirement benefits he actually
      accrued under the plans;
 
     - continuation of health, accident, disability and life insurance benefits
      for three years after his employment terminates, unless he becomes
      eligible to receive comparable benefits during the three-year period; and
                                       21
<PAGE>   27
 
     - payment of any legal fees and expenses reasonably incurred by him to
      enforce his rights under the agreement.
 
If the Internal Revenue Service subjects any payment to the named executive
officer under the change of control employment agreement to an excise tax under
Section 4999 of the Internal Revenue Code, such named executive officer will
receive an additional payment so that the amount he receives equals the amount
he would receive under the agreement if an excise tax had not been imposed.
However, this additional payment will not be made to such named executive
officer unless the payment exceeds 110% of the payments that could have been
made to him without the imposition of an excise tax.
 
The named executive officer will also receive any benefits he may have under any
other agreement with, or benefit plan or arrangement of, Comerica.

The following Compensation Committee Report and Performance Graph will not be
incorporated by reference into any of Comerica's previous filings under the
Securities Act of 1933, as amended, or the Exchange Act.
 
                         COMPENSATION COMMITTEE REPORT
 
Comerica establishes the annual compensation for Comerica's Chairman and Chief
Executive Officer based on the recommendation of the Compensation Committee to
the Board of Directors. The committee reviews and approves the annual
compensation for Comerica's President, Vice Chairman, Executive Vice Presidents
and other executive officers based on the recommendations of management. All the
members of the committee are non-employee directors.
 
COMPENSATION PHILOSOPHY
 
Comerica designed its compensation program to attract, motivate, reward and
retain superior executive talent. The program emphasizes performance-based
compensation and encourages long-term strategic decision making.
 
The principal components of the executive compensation program are base
salaries, annual and long-term management incentive awards and long-term stock
incentive awards.
 
In determining appropriate levels of compensation for the Chairman and Chief
Executive Officer, the President, the Vice Chairman, Executive Vice Presidents
and other executive officers, the committee evaluates: (1) Comerica's
performance in relation to established performance goals which are discussed
below; (2) Comerica's performance in relation to the fifty largest bank holding
companies in the United States (the "performance peer group"); and (3)
compensation levels at a selected group of fourteen super-regional bank holding
companies located primarily in the Midwest (the "compensation peer group").
 
The fifty largest bank holding companies included in the performance peer group
are substantially the same institutions as those included in the Keefe-50 Bank
Index used below in Comerica's performance graph, though there are some
differences.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
Comerica's Board of Directors relies on the Chairman and Chief Executive Officer
to provide effective leadership and execute a successful business plan for the
entire organization. Other key measures of the Chairman and Chief Executive
Officer's performance include development of the senior managers of Comerica and
the leadership role he plays within the community.
 
Subject to the Board's approval of his annual compensation, the committee
establishes Mr. Miller's base salary, management incentive award, stock option
grants and, when appropriate, restricted stock awards in amounts commensurate
with his performance and position, in accordance with Comerica's compensation
philosophy described above and in accordance with the terms of Mr. Miller's
employment agreement discussed in this Proxy Statement under the heading
"Employment Contracts and Severance Agreements."
 
BASE SALARIES
 
In the fourth quarter of 1996, Comerica, with the assistance of an independent
compensation consultant, conducted a review of the competitiveness of the
executive compensation program. Based on this review, the Committee determined
that Comerica's base salaries for the named executive officers, including the
Chief Executive Officer, were at or above the median base salaries of the
compensation peer group. The committee increased Mr. Miller's base salary by
approximately four percent to reflect his contribution to the organization's
success and to maintain his base salary at a level competitive with that of
chief executive officers in the compensation peer group.
                                       23
<PAGE>   29
 
MANAGEMENT INCENTIVE PLAN
 
The committee members believe that return on equity is a key measure of
corporate performance. Therefore, Comerica maintains a Management Incentive Plan
for executive officers which provides for incentives that are driven by
Comerica's return on equity in relation to the performance peer group and in
relation to return on equity targets which are approved annually by the
committee.
 
For 1997, the payment of incentive awards was based on Comerica achieving a
minimum return on equity of fourteen percent. Maximum incentive awards become
payable when Comerica achieves a return on equity of nineteen percent or
greater. The Committee established these targets in the first quarter of 1997.
Upon determination of Comerica's performance in relation to these targets, the
committee established a pool of awards for distribution under the incentive
plan. The distribution of individual awards to the Chairman and Chief Executive
Officer and the other participants in the program is based on corporate
performance, individual performance and individual levels of responsibility
within Comerica. Mr. Miller's award under the plan also is subject to the terms
of his employment agreement.
 
The 1997 management incentive awards for the Chairman and Chief Executive
Officer and the other named executive officers were based on the 1997 return on
equity of 20.82 percent which placed Comerica (ranked at number seven), in the
top ten among the fifty largest bank holding companies included in the
performance peer group. Comerica determined the reported return on equity by
including an adjustment equal to twenty percent of the 1996 after-tax
restructuring charge.
 
Mr. Miller's 1997 annual award under the Management Incentive Plan reflects
Comerica's return on equity performance as well as Mr. Miller's contribution to
that performance. Mr. Miller's 1997 annual cash compensation, which includes
this award and his base salary, is approximately at the 75th percentile for the
compensation peer group.
 
To reward consistent superior performance over a three-year period, the
Management Incentive Plan provides for an additional award to be paid if
Comerica's average return on equity for the most recent three-year period ranks
among the top twenty in the performance peer group. Comerica pays fifty percent
of the additional award in the form of non-transferable common stock and fifty
percent in cash. A non-transferability restriction is attached to any stock
grant which precludes the recipient from disposing of the stock prior to
retirement or other termination of employment. The stock portion of the
additional award serves to further align the interests of Comerica's senior
officers with those of the shareholders.
 
Comerica's average return on equity for the three-year period from 1995 through
1997 ranked among the top ten of the fifty largest bank holding companies in the
performance peer group. This is the second time since the inception of the plan
that a long term incentive award was made to reward for this consistent superior
performance. Mr. Miller's long term incentive payment was based on his level and
contribution to this success.
 
STOCK-BASED AWARDS
 
Comerica's key officers and employees, including all of its named executive
officers, are eligible to receive stock-based awards under Comerica's Long-Term
Incentive Plan. The plan's objective is to align the interests of Comerica's key
officers and employees with those of its shareholders.
 
Awards in 1997 consisted principally of stock option grants with exercise prices
equal to the fair market value of Comerica's common stock on the grant date.
Because executives receive value from stock option grants only in the event of
stock price appreciation, the committee believes stock options are a strong
incentive to improve long term financial performance and increase shareholder
value. Individual grants in 1997 were based on corporate performance and on
individual levels of responsibility and contributions to Comerica.
                                       24
<PAGE>   30
 
Comerica's independent compensation consultant reported that, since 1992, the
size of Comerica's stock option grants for the named executive officers has been
conservative when compared to those for Comerica's compensation peer group. It
has been the goal of Comerica to provide stock-based awards at least equal to
the median awards provided by banks of this peer group. It is also a goal of
Comerica to encourage stock ownership for all levels of employees.
 
Grants of stock options to the Chairman and Chief Executive Officer and the
other named executive officers are allocated from a pool of options which is
created each year based on: (1) Comerica's overall performance and (2) a
percentage of each officer's base salary. Each named executive officer's grant
from the stock pool is based on the committee's assessment of his or her
individual performance.
 
STOCK OWNERSHIP GUIDELINES
 
Effective January 1, 1995, Comerica implemented stock ownership guidelines which
encourage senior officers to own a significant number of shares of Comerica's
common stock. The stock ownership targets require Comerica's senior officers to
own a number of shares with a value equal to the senior officer's annual salary
times a certain multiple. Comerica encourages its senior officers to achieve the
targeted stock ownership levels within five years of January 1, 1995 or of
becoming a senior officer. The Chairman and Chief Executive Officer, President,
Vice Chairman and every executive officer who has been an Executive Vice
President for five years have met their respective stock ownership targets.

DEDUCTIBILITY OF EXECUTIVE COMPENSATION
 
The committee's objective is to structure Comerica's executive compensation
programs to maximize the deductibility of executive compensation under the
Internal Revenue Code. However, the committee reserves the right in the exercise
of its business judgment to establish appropriate compensation levels for
executive officers that may exceed the limits on tax deductibility established
under Section 162(m) of the Internal Revenue Code. Currently all executive
officer compensation is tax deductible.

Upon recommendation of the Audit and Legal Committee, the Board of Directors
selected Ernst & Young LLP as independent accountant to audit Comerica's
financial statements for 1998. Ernst & Young also audited Comerica's financial
statements for 1997. Representatives of Ernst & Young will attend the Annual
Meeting and you may ask questions of Ernst & Young if you wish.
 
                             SHAREHOLDER PROPOSALS
 
If you would like Comerica to consider a proposal for inclusion in Comerica's
Proxy Statement for the 1999 Annual Meeting of Shareholders, you must ensure
that Comerica receives the proposal no later than December 11, 1998. Proposals
must comply with applicable laws and regulations and you must mail the proposal
to Comerica by certified or registered mail to the Corporate Secretary, Comerica
Incorporated, Comerica Tower at Detroit Center, 500 Woodward Avenue, 33rd Floor,

                         ANNUAL REPORT TO SHAREHOLDERS
 
Comerica mailed to you the 1997 Annual Report to Shareholders, containing
financial statements and other information about the operations of Comerica for
the year ended December 31, 1997. You should not regard the 1997 Annual Report
as proxy soliciting material.
 
                                 OTHER MATTERS
 
The Board of Directors is not aware of any other matter to be presented at the
Annual Meeting. The Board of Directors does not intend to submit any additional
matters for a vote at the meeting and no shareholder has provided the required
notice of the shareholder's intention to propose any matter at the meeting.
 
Under Comerica's bylaws, the Board of Directors may, without notice, properly
submit additional matters for a vote at the meeting. If the Board of Directors
does so, the shares represented by Proxies in the accompanying form will be
voted with respect to the matter in accordance with the judgment of the person
or persons voting the shares.
 
Under Comerica's bylaws, shareholders of Comerica must provide advance notice to
Comerica if they wish to nominate persons for election as directors or propose
items of business at an annual meeting of Comerica's shareholders. In the case
of an annual meeting of shareholders, the shareholder must deliver this notice
not less than 60 days nor more than 90 days prior to the anniversary date of the
immediately preceding annual meeting of shareholders. If, however, Comerica
calls the annual meeting of shareholders for a date that is not within 30 days
before or after this anniversary date, Comerica must receive the shareholder's
notice not later than the close of business on the 10th day following the day on
which notice of the date of the annual meeting was mailed or public disclosure
of the date of the annual meeting was made, whichever occurs first. In the case
of a special meeting of shareholders called for the purpose of electing
directors, the shareholder's written notice must be delivered not later than the
close of business on the 10th day following the day on which notice of the date
of the special meeting was mailed or public disclosure of the date of the
special meeting was made, whichever occurs first. Any
