NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) COMERICA INCORPORATED AND SUBSIDIARIES

NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the nine months ended September 30, 2002, are not necessarily indicative of the results that may be expected for the year ending December 31, 2002. Certain items in prior periods have been reclassified to conform to the current presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the annual report of Comerica Incorporated and Subsidiaries (the "Corporation") on Form 10-K for the year ended December 31, 2001.
Comerica merged with Imperial Bancorp (Imperial), a $7 billion (assets) bank holding company, in the first quarter of 2001, in a transaction accounted for as a pooling of interests.
The Corporation uses derivative financial instruments, including foreign exchange contracts, to manage the Corporation's exposure to interest rate and foreign currency risks. All derivative instruments are carried at fair value as either assets or liabilities on the balance sheet. The accounting for changes in the fair value (i.e. gains or losses) of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the

Corporation designates the hedging instrument, based upon the exposure being hedged, as either a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. For further information, see Note 10.
In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets". The Corporation adopted SFAS No. 142 on January 1, 2002. Under SFAS No. 142, goodwill is no longer amortized, but is subject to annual impairment tests. Other intangible assets that do not have an indefinite life continue to be amortized over their useful lives. For further information on the adoption of SFAS No. 142, see Note 4.
In the third quarter of 2002, the Corporation adopted the fair value method of accounting for stock options, as outlined in SFAS No. 123, "Accounting for Stock-Based Compensation," effective for stock options granted subsequent to December 31, 2001. Financial results for the second quarter of 2002 have been restated in accordance with SFAS No. 123. Under SFAS No. 123, compensation expense equal to the fair value of stock-based compensation as of the date of grant is recognized over the vesting period. For further information on the adoption of SFAS No. 123, see Note 12.

NOTE 2 - INVESTMENT SECURITIES

At September 30, 2002, investment securities having a carrying value of $2.0 billion were pledged, primarily with the Federal Reserve Bank and state and local government agencies. Securities are pledged where permitted or required by law to secure liabilities and public and other deposits, including deposits of the State of Michigan of $115 million.

SFAS No. 114, "Accounting by Creditors for Impairment of a Loan," considers a loan impaired when it is probable that interest and principal payments will not be made in accordance with the contractual terms of the loan agreement. Consistent with this definition, all nonaccrual and reduced-rate loans (with the exception of residential mortgage and consumer loans) are impaired. Impaired loans include $24 million of loans which were formerly on nonaccrual status, but were restructured and met the requirements to be restored to an accrual basis. These restructured loans are performing in accordance with their modified terms, but, in accordance with impaired loan disclosures, must continue to be disclosed as impaired for the remainder of the calendar year of the restructuring. Impaired loans averaged $647 million and $645 million for the three and nine month periods ended September 30, 2002, compared to $561 million and $501 million, respectively, for the comparable periods last year. The following presents information regarding the period-end balances of impaired loans:

Those impaired loans not requiring an allowance represent loans for which the fair value exceeded the recorded investment in the loan.

NOTE 4 - GOODWILL AND OTHER INTANGIBLE ASSETS - ADOPTION OF SFAS NO. 142

In accordance with the Corporation's adoption of SFAS No. 142, the Corporation performed the first required impairment test of goodwill and indefinite-lived intangible assets as of January 1, 2002. Based on this test, the Corporation was not required to record a transition adjustment upon adoption. Goodwill was again evaluated for impairment as of July 1, 2002. As a result of this test, the Corporation was required to record a goodwill impairment charge of $86 million in the third quarter of 2002. This charge resulted from the continued decline in equity markets, and its related impact on the valuation of the Corporation's investment advisory reporting unit (Munder), which is a part of the Investment Bank for business segment reporting purposes. Further declines in equity markets could trigger additional goodwill impairment charges related to this unit in future quarters. The fair value of Munder used in the determination of the impairment charge was based on a valuation prepared by an investment banker not affiliated with the Corporation. The valuation used a combination of valuation techniques, including discounted cash flows and the prices of external comparable businesses.

NOTE 9 - MERGER-RELATED AND RESTRUCTURING CHARGES

The Corporation recorded merger-related and restructuring charges of $173 million in 2001 related to the acquisition of Imperial, of which $25 million was recorded in the provision for credit losses. The remaining $148 million of charges were recorded in noninterest expenses. The Corporation also recorded a 2001 restructuring charge of $4 million related to its subsidiary, Official Payments Corporation (OPAY). The OPAY restructuring charge was recorded net of the portion of the charge attributable to the minority shareholders in OPAY. The Corporation sold its OPAY subsidiary as of July 24, 2002, therefore, no liability remains for OPAY restructuring charges as of the sale date.
The 2001 Imperial restructuring charge included employee termination costs, other employee related costs, a charge related to conforming policies, facilities and operations and other charges. Employee termination costs included the cost of severance, outplacement and other benefits associated with the involuntary termination of employees, primarily senior management and employees in corporate support and data processing functions. A total of 352 employees were terminated in 2001 as part of the restructuring plan. Other employee-related costs included cash payments related to change in control provisions in employment contracts and retention bonuses. Charges related to conforming policies represented costs associated with conforming the credit and accounting policies of Imperial with those of the Corporation. The Corporation also incurred facilities and operations charges associated with closing excess facilities and replacing signage. Other merger-related restructuring costs were primarily comprised of investment banking, accounting, consulting and legal fees. As a result of the Imperial restructuring, the Corporation's annual savings on operating expenses are estimated to be $60 million, beginning in 2002.

(1) Notional or contract amounts, which represent the extent of involvement in the derivatives market, are generally used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk, and are not reflected in the consolidated balance sheets.

(2) Represents credit risk, which is measured as the cost to replace, at current market rates, contracts in a profitable position. Credit risk is calculated before consideration is given to bilateral collateral agreements or master netting arrangements that effectively reduce credit risk.

(3) The fair values of derivatives and foreign exchange contracts generally represent the estimated amounts the Corporation would receive or pay to terminate or otherwise settle the contracts at the balance sheet date. The fair values of all derivatives and foreign exchange contracts are reflected in the consolidated balance sheets.

NOTE 10 - DERIVATIVES AND FOREIGN EXCHANGE CONTRACTS (CONTINUED)

Risk Management

Fluctuations in net interest income due to interest rate risk result from the composition of assets and liabilities and the mismatches in the timing of the repricing of these assets and liabilities. In addition, external factors such as interest rates, and the dynamics of yield curve and spread relationships can affect net interest income. The Corporation utilizes simulation analyses to project the sensitivity of the Corporation's net interest income to changes in interest rates. Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs cash instruments, such as investment securities, as well as derivative financial instruments and foreign exchange contracts, to manage exposure to these and other risks, including liquidity risk.
As an end-user, the Corporation accesses the interest rate markets to obtain derivative instruments for use principally in connection with asset and liability management activities. As part of a fair value hedging strategy, the Corporation has entered into interest rate swap agreements for interest rate risk management purposes. The interest rate swap agreements effectively modify the Corporation's exposure to interest rate risk by converting fixed-rate deposits and debt to a floating rate. These agreements involve the receipt of fixed rate interest amounts in exchange for floating rate interest payments over the life of the agreement, without an exchange of the underlying principal amount. For instruments that support a fair value hedging strategy, no ineffectiveness was required to be recorded in the statement of income.
As part of a cash flow hedging strategy, the Corporation has entered into predominantly 3-year interest rate swap agreements that effectively convert a portion of its existing and forecasted floating-rate loans to a fixed-rate basis, thus reducing the impact of interest rate changes on future interest income over

the next 3 years. Approximately 22 percent ($9 billion) of the Corporation's outstanding loans were designated as the hedged items to interest rate swap agreements at September 30, 2002. During the three and nine month periods ended September 30, 2002, interest rate swap agreements designated as cash flow hedges increased interest and fees on loans by $83 and $272 million, respectively, compared to $53 and $89 million, respectively, for the comparable periods last year. The ineffectiveness associated with these hedging instruments was not significant to the Corporation's statement of income in the third quarter of 2002. If interest rates and interest curves remain at their current levels, the Corporation expects to reclassify $186 million of net gains on derivative instruments from accumulated other comprehensive income to earnings during the next twelve months due to receipt of variable interest associated with the existing and forecasted floating-rate loans.
Management believes these strategies achieve an optimal relationship between the rate maturities of assets and their funding sources which, in turn, reduces the overall exposure of net interest income to interest rate risk, although, there can be no assurance that such strategies will be successful. The Corporation also uses various other types of financial instruments to mitigate interest rate and foreign currency risks associated with specific assets or liabilities, which are reflected in the table above. Such instruments include interest rate caps and floors, foreign exchange forward contracts, and foreign exchange cross-currency swaps.
The following table summarizes the expected maturity distribution of the notional amount of interest rate swaps used for risk management purposes and indicates the weighted average interest rates associated with amounts to be received or paid on interest rate swap agreements as of September 30, 2002. The swaps are grouped by the assets or liabilities to which they have been designated.

NOTE 10 - DERIVATIVES AND FOREIGN EXCHANGE CONTRACTS (CONTINUED)

The Corporation had commitments to purchase investment securities for its trading account and available for sale portfolio totaling $522 million at September 30, 2002 and totaling $67 million at December 31, 2001. Commitments to sell investment securities related to the trading account totaled $22 million at September 30, 2002, and $10 million at December 31, 2001. Outstanding commitments expose the Corporation to both credit and market risk.

Customer-Initiated and Other

The Corporation earns additional income by executing various derivative transactions, primarily foreign exchange contracts and interest rate contracts, at the request of customers. Market risk inherent in customer-initiated contracts is often mitigated by taking offsetting positions. The Corporation generally does not speculate in derivative financial instruments for the purpose of profiting in the short-term from favorable movements in market rates. Average fair values and income from customer-initiated and other foreign exchange contracts and interest rate contracts were not material for the nine-month periods ended September 30, 2002 and 2001 and for the year ended December 31, 2001.

NOTE 12 - STOCK-BASED COMPENSATION

In the third quarter of 2002, the Corporation adopted the fair value method of accounting for stock options, as outlined in SFAS No. 123. Transition rules require that all current year grants be accounted for under the fair value method in the year of adoption, thus, the new method was applied prospectively to all grants made after December 31, 2001. Substantially all current year grants were issued in the second quarter of 2002. Under SFAS No. 123, compensation expense, equal to the fair value of stock-based compensation as of the date of grant, is recognized over the vesting period. Awards under the Corporation's plans vest over periods ranging from one to four years. Therefore, the expense related to stock-based compensation included in the determination of net income for 2002 is less than which would have been recognized if the fair value method had been applied to all awards since the original effective date of SFAS 123. Options granted prior to January 1, 2002 continue to be accounted for under APB Opinion No. 25, "Accounting for Stock Issued to Employees".
The fair value of stock options granted was estimated at the date of grant using a Black-Scholes option pricing model. The Black-Scholes model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferrable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. The model may not necessarily provide a reliable single measure of the fair value of employee and director options. The Corporation's employee and director stock options have characteristics significantly different from those of traded options and changes in subjective input assumptions can materially affect the fair value estimate.

The net income and diluted earnings per share impacts were $7 million and $0.04, respectively, for the nine months ended September 30, 2002, and $4 million and $0.02, respectively, for the three months ended September 30, 2002.

ITEM 2. Management's Discussion and Analysis of Results of Operations and Financial Condition

Results of Operations

Net income for the quarter ended September 30, 2002 was $24 million, down $185 million, or 89 percent, from $209 million reported for the third quarter of 2001. Quarterly diluted net income per share decreased to $0.14 from $1.14 a year ago. Return on average common shareholders' equity was 1.93 percent and return on average assets was 0.19 percent, compared to 17.68 percent and 1.68 percent, respectively, for the comparable quarter last year. The decline in earnings in the third quarter 2002 from the comparable quarter last year resulted primarily from a $227 million ($148 million after-tax, or $0.84 per diluted share) increase in provision for credit losses due to the continued uncertainty of an economic recovery and higher noninterest expenses resulting from a third quarter 2002 goodwill impairment charge of $86 million ($56 million after-tax, or $0.31 per diluted share), partially offset by third quarter 2001 Imperial restructuring charges of $18 million ($11 million after-tax, or $0.06 per diluted share).

Net income for the first nine months of 2002 was $2.22 per diluted share, or $395 million, compared to $2.77 per diluted share, or $511 million, for the same period in 2001, decreases of 20 percent and 23 percent, respectively. Return on average common shareholders' equity was 10.79 percent and return on average assets was 1.04 percent for the first nine months of 2002, compared to 14.74 percent and 1.38 percent, respectively, for the first nine months of 2001. The decline in earnings in the nine months ended September 30, 2002 from the comparable period last year resulted from a $366 million ($238 million after-tax, or $1.34 per diluted share) increase in provision for credit losses primarily for the reasons cited in the quarterly discussion in the preceding paragraph and Argentine transfer risk reserves associated with a second quarter U.S. bank regulatory directive. The third quarter 2002 goodwill impairment charge

-27-

discussed above and a decrease in securities gains and losses also contributed to the earnings decline. Partially offsetting the decline in earnings was a $33 million increase in net interest income over the comparable period last year and unusual items in 2001, including a one-time charge related to long-term incentive plans at an unconsolidated subsidiary of $53 million ($34 million after-tax, or $0.19 per diluted share) and Imperial restructuring charges totaling $152 million ($114 million after-tax, or $0.63 per diluted share), partially offset the earnings decline.

Net Interest Income

The rate-volume analysis in Table I details the components of the change in net interest income on a fully taxable equivalent (FTE) basis for the quarter ended September 30, 2002. On a FTE basis, net interest income increased to $529 million for the three months ended September 30, 2002, from $527 million for the comparable quarter in 2001. Average earning assets increased three percent when compared to the third quarter of last year, while the net interest margin decreased to 4.46 percent for the three months ended September 30, 2002, from 4.59 percent for the comparable three months of 2001. The margin decline was primarily due to compressed loan spreads, partially offset by the benefit from a 16 percent increase in average noninterest-bearing deposits. This increase is primarily attributed to the strong growth of title and escrow deposits in the California-based Financial Services business.

Table II provides an analysis of net interest income for the first nine months of 2002. On a FTE basis, net interest income for the nine months ended September 30, 2002, was $1,602 million compared to $1,569 million for the same period in 2001. This increase was due to a two percent increase in average earning assets and a relatively stable net interest margin supported by strong growth in average noninterest-bearing deposits, up 12 percent when compared to the first nine months of 2001 for the same reason cited in the quarterly discussion. The net interest margin for the first nine months ended September 30, 2002, decreased to 4.59 percent, from 4.60 percent for the same period in 2001.

Provision for Credit Losses

The provision for credit losses was $285 million for the third quarter of 2002, compared to $58 million for the same period in 2001. The provision for the first nine months of 2002 was $533 million compared to $167 million for the same period in 2001. The Corporation establishes this provision to maintain an adequate allowance for credit losses, which is discussed in the section entitled "Allowance for Credit Losses and Nonperforming Assets." The significant increase in the provision for credit losses in the third quarter 2002 resulted from the continued uncertainty in the economy and a decision to sell certain loans. The economic uncertainty has impacted many of the Corporation's customers, as evidenced by a higher allowance, even after increased net charge-offs. The third quarter 2002 provision for credit losses also included $104 million to cover charge-offs in conjunction with management's decision to sell certain loans. These loans were reclassified from loans to short-term investments during the quarter and total $116 million net of charge-offs at September 30, 2002. Also included in the provision for credit losses for the first nine months of 2002 is an increase in reserves for Argentina. Included in the provision for the first nine months of 2001 is a $25 million merger-related charge to conform the credit policies of Imperial with Comerica.

Noninterest Income

Noninterest income was $216 million for the three months ended September 30, 2002, a decrease of $8 million, or four percent, over the same period in 2001. Included in third quarter 2002 noninterest income is a pre-tax gain of $12 million related to the sale of the Corporation's OPAY subsidiary and a $5 million impairment charge on deferred distribution costs related to the Corporation's Munder Capital Management subsidiary (Munder), further discussed below. Included in the third quarter 2001 is a pre-tax gain of $21 million on the sale of the Corporation's ownership in an ATM network provider and a $14 million impairment

-33-

charge on deferred distribution costs. Excluding the effects of the gains on sale of businesses and impairment charges, gains and losses on securities, warrant income and divestitures, noninterest income decreased $3 million, or two percent, over the same period last year. Certain of the Corporation's noninterest income, primarily fiduciary income and investment advisory revenue, is at risk to fluctuations in the market values of underlying assets, particularly equity securities. Other income, primarily brokerage service fees, is at risk to changes in the level of market activity. The noninterest income decline reflects a $10 million decrease in this market-related revenue, excluding the deferred distribution costs impairment charges in both periods. This decrease was partially offset by increased revenue on bank-owned life insurance due to death benefits received and increased earnings on policies held.
The Corporation recorded a $5 million pre-tax deferred distribution costs impairment charge in the third quarter of 2002 related to the Corporation's Munder subsidiary. This charge resulted from a continued reassessment of the recoverability of the unamortized cost of commissions to brokers for selling Class B mutual fund shares. Net asset values in these funds have declined as general market conditions continued to weaken. This prompted the Corporation's revaluation of expected future cash flows from the funds, which are based on a percentage of assets under management and early redemption fees over a prescribed number of years. Net remaining deferred distribution costs at September 30, 2002 were $20 million. Given net asset values at September 30, 2002, it would take a decline of approximately 10 percent in the assets under management associated with those costs to trigger further impairment, which at that level would be approximately $2 million. Each additional five percent decline results in a further impairment of $1 million.

For the first nine months of 2002, noninterest income was $646 million, an increase of $33 million, or five percent, from the first nine months of 2001. In addition to the unusual items cited above, noninterest income for the first

-34-

nine months of 2002 included $9 million of non-taxable proceeds from bank-owned life insurance policies from the death of an executive. Noninterest income in the first nine months of 2001 was reduced by a total of $40 million of deferred distribution costs impairment charges and a one-time $57 million charge related to long-term incentive plans at an unconsolidated subsidiary. Noninterest income in the first nine months of 2001 also included $11 million in net gains resulting from the purchase and subsequent sale, all within the first quarter, of interest rate derivative contracts which failed to meet the Corporation's risk-reduction criteria. Excluding the effect of the large unusual items noted above, gains and losses on securities, warrant income and divestitures, noninterest income in the first nine months of 2002 decreased $5 million, or one percent, over the same period in 2001. Market-related income revenue declined $26 million, excluding the deferred distribution costs impairment charges in both periods, for the reasons cited in the quarterly discussion. This was offset by increases in service charges on deposit accounts, reflecting the benefit of lower earnings credit allowances provided to business customers, and higher levels of revenue on bank-owned life insurance.

Noninterest Expenses

Noninterest expenses were $433 million for the quarter ended September 30, 2002, an increase of $60 million, or 16 percent, from the comparable quarter in 2001. Noninterest expenses in the third quarter of 2002 include a goodwill impairment charge of $86 million as a result of the Corporation's annual evaluation of goodwill in accordance with SFAS No. 142 and a $6 million charge related to the Corporation's third quarter 2002 adoption of the fair value method of accounting for stock options. Additional information on the goodwill impairment charge and the adoption of the fair value method of accounting for stock options can be found in Notes 4 and 12, respectively, to the unaudited consolidated financial statements in this report. Noninterest expenses in the

-35-

third quarter of 2001 included merger-related and restructuring costs related to the Imperial Bancorp acquisition of $18 million and goodwill amortization of $8 million. Goodwill amortization was discontinued January 1, 2002, as a result of new accounting rules. Excluding these items and the impact of divestitures, noninterest expenses in the third quarter of 2002 decreased by $3 million, or one percent, over the same period in 2001. Contributing to this decline was savings in customer services expense of $6 million due to reduced credits provided to customers as a result of the lower interest rate environment.

For the nine months ended September 30, 2002, noninterest expenses were $1,129 million, a decrease of $83 million, or seven percent, from the comparable period of 2001. Included in the first nine months of 2002 was a total charge of $11 million related to the Corporation's adoption of the fair value method of accounting for stock options and the goodwill impairment charge discussed above. Included in the first nine months of 2001 were restructuring charges totaling $127 million and a reduction in other noninterest expenses of $5 million that resulted from recording the minority interest holders' share of the long-term incentive plan charge discussed in noninterest income above. Also affecting the first nine months of 2001 was $24 million in goodwill amortization. Excluding these items and the impact of divestitures, noninterest expenses in the first nine months of 2002 decreased by $21 million, or two percent, over the same period in 2001. This decrease is primarily attributed to lower salaries and benefits of $10 million, due primarily to reduced revenue related incentives, and a reduction in customer services expense of $11 million for the reasons cited in the quarterly discussion.

Provision for Income Taxes

The provision for income taxes for the third quarter of 2002 totaled $2 million, compared to $110 million reported for the same period a year ago. The effective tax rate was eight percent for the third quarter of 2002, compared to

-36-

35 percent for the same quarter of 2001. The provision for the first nine months of 2002 was $188 million compared to $289 million for the same period of 2001. The effective tax rate was 32 percent for the first nine months of 2002 and 36 percent for the first nine months of 2001. The low effective tax rate in the third quarter 2002 resulted from the significant reduction in income before income taxes, which increased the proportion of permanent tax differences to pre- tax income. The effective tax rate in the first nine months of 2002 was impacted by increased non-taxable revenue on bank-owned life insurance policies. The effective tax rate in the first nine months of 2001 was affected by adjustments in the first quarter to Imperial's tax liabilities at the merger date, partially offset by a $7 million tax benefit related to the Imperial acquisition that was immediately recognizable, but only after Imperial became part of Comerica.

Financial Condition

Total assets were $52.6 billion at September 30, 2002, compared with $50.7 billion at year-end 2001 and $49.7 billion at September 30, 2001. The Corporation has experienced an increase (one percent) in total loans since December 31, 2001. Management believes that this slight increase reflects the cautiousness of borrowers in an uncertain economy. Weak loan demand, coupled with an increase in noninterest-bearing deposits, resulted in an increase in short-term investments of $801 million since year-end 2001. This increase was primarily attributable to higher amounts of federal funds sold.

Total liabilities increased $1.8 billion, or four percent, since December 31, 2001, to $47.7 billion. Total deposits increased eight percent to $40.6 billion at September 30, 2002, from $37.6 billion at year-end 2001 due to growth in noninterest-bearing deposits. The growth in noninterest-bearing deposits is primarily attributed to the strong growth of title and escrow deposits in the California-based Financial Services business. The deposit increase was partially offset in short-term borrowings, which decreased $1.3 billion since

-37-

December 31, 2001, to $689 million at September 30, 2002. Medium- and long-term debt decreased $16 million to $5.5 billion at September 30, 2002.

Allowance for Credit Losses and Nonperforming Assets

The allowance for credit losses represents management's assessment of probable losses inherent in the Corporation's loan portfolio, including all binding commitments to lend. The allowance provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent but that have not been specifically identified. The Corporation allocates the allowance for credit losses to each loan category based on a defined methodology which has been in use, without material change, for several years. Internal risk ratings are assigned to each business loan at the time of approval and are subject to subsequent periodic reviews by the senior management of the Credit Policy Group. The Corporation defines business loans as those belonging to the commercial, international, real estate construction, commercial mortgage and lease financing categories. The Corporation performs a detailed credit quality review quarterly on large business loans which have deteriorated below certain levels of credit risk and allocates a specific portion of the allowance to such loans based upon this review. The portion of the allowance allocated to the remaining business loans is determined by applying projected loss ratios to each risk rating based on numerous factors identified below. The portion of the allowance allocated to consumer loans is determined by applying projected loss ratios to various segments of the loan portfolio. Projected loss ratios incorporate factors such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts. The allocated allowance was $540 million at September 30, 2002, a decrease of $6 million from year-end 2001. This decrease was attributable, in part, to the decision to sell certain nonperforming loans in the third quarter 2002. These loans were written down to net realizable value and

-38-

transferred to short-term investments, thus eliminating the need for an allocated allowance. Offsetting this reduction was increased reserves related to Argentine and non-trade Brazilian exposure.

Actual loss ratios experienced in the future could vary from those projected. This uncertainty occurs because other factors affecting the determination of probable losses inherent in the loan portfolio may exist which are not necessarily captured by the application of historical loss ratios. An unallocated allowance is maintained to capture these probable losses. The unallocated portion of the loss reserve reflects management's view that the reserve should have a margin that recognizes the imprecision underlying the process of estimating expected credit losses. Determination of the probable losses inherent in the portfolio, which are not necessarily captured by the allocated methodology discussed above, involves the exercise of judgement. Factors which were considered in the evaluation of the adequacy of the Corporation's unallocated reserve include portfolio exposures to the healthcare, technology and life sciences, entertainment and energy industries, as well as Latin American transfer risks and the risk associated with new customer relationships. The unallocated allowance was $249 million at September 30, 2002, an increase of $140 million from December 31, 2001. This increase results from the Corporation's belief that the continued uncertainty of an economic recovery, and its impact on the Corporation's customers, requires increased unallocated coverage for all factors considered in the unallocated allowance.

Management also considers industry norms and the expectations from rating agencies and banking regulators in determining the adequacy of the allowance. The total allowance, including the unallocated amount, is available to absorb losses from any segment of the portfolio. Unanticipated economic events, including political, economic and regulatory stability in countries where the Corporation has a concentration of loans, could cause changes in the credit characteristics of the portfolio and result in an unanticipated increase in the

-39-

allocated allowance. Inclusion of other portfolio exposures in the unallocated allowance, as well as significant increases in the current portfolio exposures, could increase the amount of the unallocated allowance. Either of these events, or some combination, may result in the need for additional provision for credit losses in order to maintain an allowance that complies with credit risk and accounting policies.

The Corporation is closely monitoring its Argentine and Brazilian exposure as a result of recent political and economic events in those countries. The total Argentine exposure at September 30, 2002, was $103 million and consisted of $83 million of loans, $11 million of securities and $9 million of unfunded commitments. This represents a decrease of $116 million from total Argentine exposure of $219 million at December 31, 2001. Allocations in the allowance for credit losses cover approximately 50 percent of loans and unfunded commitments. The total Brazilian exposure at September 30, 2002, was $576 million and consisted of $447 million of loans, $52 million of securities and $77 million of unfunded commitments. This represents a decrease of $136 million from total Brazilian exposure of $712 million at December 31, 2001. Allocations in the allowance for credit losses cover approximately five percent of loans and unfunded commitments. At September 30, 2002, the Corporation had $39 million of loans and $8 million in securities related to Argentina and $5 million of loans related to Brazil that were reported in nonperforming assets.

At September 30, 2002, the allowance for credit losses was $789 million, an increase of $134 million since December 31, 2001. The allowance as a percentage of total loans was 1.90 percent, compared to 1.59 percent at December 31, 2001. As a percentage of nonperforming assets, the allowance was 123 percent at September 30, 2002, versus 105 percent at year-end 2001.

The continued uncertainty in the economy, and its impact on the Corporation's customers, has required increased levels of allowance to be maintained on the Corporation's business loans. These increased allowance levels

-40-

have also impacted the allowance coverage of nonperforming assets.

Net charge-offs for the third quarter of 2002 were $258 million, or 2.44 percent of average total loans, compared with $58 million, or 0.56 percent, for the third quarter of 2001. The increase in net charge-offs was attributable to the decision to sell certain nonperforming loans in the third quarter 2002 and the continued uncertainty of an economic recovery, and its impact on the Corporation's customers. Net charge-offs in the third quarter 2002 on loans transferred to short-term investments totaled $104 million. Nonperforming assets increased $13 million, or two percent, since December 31, 2001, and were categorized as follows:

Loans to customers in the automotive industry comprised 12 percent of nonperforming loans at September 30, 2002, and was the only industry classification comprising more than 10 percent of nonperforming loans. Six credits in excess of $10 million were added to nonperforming loans during the third quarter 2002. The largest nonaccrual loan at September 30, 2002, was to an automotive supplier totaling $24 million. Approximately 46 percent of total nonperforming assets at September 30, 2002 were Shared National Credit Program

-41-

(SNC) loans. SNC loans are large credits shared by multiple financial institutions and reviewed by regulatory authorities at the lead or agent bank level. These loans comprised approximately 20 percent of total loans at September 30, 2002. Nonperforming assets as a percentage of total loans and other real estate were 1.54 percent at September 30, 2002 and 1.52 percent at December 31, 2001.

The following table presents a roll-forward of nonaccrual loans from December 31, 2001 to September 30, 2002, based on an analysis of nonaccrual loans with book balances greater than $2 million.

* Net change related to nonaccrual loans with balances less than $2 million, other than net charge-offs, included in Payments/Other.

During the third quarter 2002, $276 million of loans were transferred to nonaccrual status. Included were 35 loans with balances greater than $2 million. Six of these loans were greater than $10 million (totaling $124 million) to customers in the manufacturing and service sectors.

Assuming the economy remains unchanged from current levels, the Corporation's management expects that nonperforming assets will decrease slightly to between $550-625 million by December 31, 2002. The reduction in nonperforming assets that will result from the expected sale of $116 million of loans held for sale will be partially offset by assets transferred to nonaccrual. Charge-offs are expected to decline significantly from third quarter 2002 levels in the fourth quarter of 2002, and are projected to be in the $60-80 million range. As of November 7, 2002, the Corporation had sold $112 million of the $116 million of nonaccrual loans categorized as held for sale at September 30, 2002. Gains

-42-

and losses resulting from the sale of this portfolio of loans are not expected to be material.

Capital

Common shareholders' equity, excluding the $67 million increase in other comprehensive income, remained relatively flat from December 31, 2001 to September 30, 2002. The retention of $143 million of current year earnings and the effect of employee stock plan activity, which increased common shareholders' equity $63 million, were offset by the decrease in equity of $210 million that resulted from repurchasing approximately 3.5 million shares of common stock in the open market during the first nine months of 2002.

Capital ratios exceed minimum regulatory requirements as follows:

                                                              SEPTEMBER 30,    DECEMBER 31,

Tier 1 common capital ratio                                       7.32%           7.30%
Tier 1 risk-based capital ratio (4.00% - minimum)                 7.99%           7.98
Total risk-based capital ratio (8.00% - minimum)                 11.71%          11.70

At September 30, 2002, the capital ratios of all the Corporation's banking subsidiaries exceeded the minimum ratios required of "well capitalized" institutions as defined in the final rule under FDICIA.

Accounting Policies

The Corporation's consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described in Note 1 to the consolidated financial statements included in the Corporation's 2001 Annual Report, as updated in Note 1 to the unaudited consolidated financial statements in this report. These policies require numerous estimates and strategic or economic assumptions which may prove inaccurate or subject to variations and may significantly affect the Corporation's reported results for the period or in future periods. Changes in

-43-

underlying factors, assumptions or estimates in any of these areas could have a material impact on the Corporation's future financial condition and results of operations. In management's opinion, some of these areas have a more significant impact than others on the Corporation's financial reporting. This is because these policies apply to areas of relatively greater business importance, to matters for which there is a range of possible outcomes and/or require a more subjective decision-making process on the part of management. For the Corporation, these areas currently include accounting for the allowance for credit losses, pension costs, private equity and venture capital investments, deferred distribution costs and goodwill.

Pension assumptions will be evaluated and reset prior to January 1, 2003. Equity markets and interest environments impact these assumptions. Declines in equity markets in recent years and the current low-interest-rate environment will impact pension expense for 2003. The Corporation's pension assumptions for 2002 included a 10 percent long-term rate of return on plan assets and a 7.4 percent discount rate. For each 0.25 percentage point change in the long-term rate of return assumption, pension expense changes by approximately $2 million. For each 0.25 percentage point change in the discount rate assumption, pension expense changes by approximately $4 million. For more information on pension assumptions, refer to Note 15 to the consolidated financial statements included in the Corporation's 2001 annual report.

Other Matters

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." The Statement covers legal obligations that are identifiable by the entity upon acquisition and construction, and during the operating life of a long-lived asset. Identified retirement obligations would be recorded as a liability with a corresponding amount capitalized as part of the asset's carrying amount. The capitalized retirement cost asset would be

-44-

amortized to expense over the asset's useful life. The Statement is effective January 1, 2003 for calendar year companies. The Corporation does not believe that the impact of adoption of SFAS No. 143 will have a material impact on the Corporation's financial position or results of operations.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Net interest income is the predominant source of revenue for the Corporation. Interest rate risk arises primarily through the Corporation's core business activities of extending loans and accepting deposits. The Corporation actively manages its material exposure to interest rate risk. Management attempts to evaluate the effect of movements in interest rates on net interest income and uses interest rate swaps and other instruments to manage its interest rate risk exposure. The primary tool used by the Corporation in determining its exposure to interest rate risk is net interest income simulation analysis. The net interest income simulation analysis performed at the end of each quarter reflects changes to both interest rates and loan, investment and deposit volumes. The measurement of risk exposure at September 30, 2002 for a 200 basis point decline in short-term interest rates identified approximately $108 million, or 4.9%, of forecasted net interest income at risk over the next 12 months. If short-term interest rates rise 200 basis points, forecasted net interest income would be enhanced by approximately $145 million, or 6.6%.

Secondarily, the Corporation utilizes a traditional interest sensitivity gap measure and economic value of equity analysis as alternative measures of interest rate risk exposure. At September 30, 2002, all three measures of interest rate risk were within established corporate policy guidelines. For further discussion of interest rate risk, and other market risks, see Note 10 and pages 37-41 of the Corporation's 2001 Annual Report.

ITEM 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. The Corporation's Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Corporation's disclosure controls and procedures (as such term is defined in Rules 13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of a date within 90 days prior to the filing date of this quarterly report (the "Evaluation Date"). Based on the evaluation, such officers have concluded that, as of the Evaluation Date, the Corporation's disclosure controls and procedures are effective in alerting them on a timely basis to material information relating to the Corporation (including its consolidated subsidiaries) required to be included in the Corporation's periodic filings under the Exchange Act.

(b) Changes in Internal Controls. Since the Evaluation Date, there have not been any significant changes in the Corporation's internal controls or in other factors that could significantly affect such controls.

Forward-looking statements

This report includes forward-looking statements as that term is used in securities laws. All statements regarding Comerica's expected financial position, strategies and growth prospects and general economic conditions expected to exist in the future are forward-looking statements. The words, "anticipates", "believes", "estimates", "seeks", "plans", "intends" and similar expressions, as they relate to Comerica or its management, are intended to identify forward-looking statements. Although Comerica believes that the expectations reflected in these forward-looking statements are reasonable and has based these expectations on the beliefs and assumptions Comerica has made, such expectations may prove incorrect. Numerous factors, including unknown risks and uncertainties, could cause variances in these projections and their underlying assumptions. Such factors are changes in interest rates, changes in the accounting or tax treatment of any particular item, changes in industries in which Comerica has a concentration of loans, or the political, economic and regulatory stability in countries where Comerica operates, changes in the level of fee income, changes in general economic conditions and related credit and market conditions and the impact of regulatory responses to any of the foregoing. Forward-looking statements speak only as of the date they are made. Comerica does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward- looking statements are made.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings.

Several of the Corporation's banking subsidiaries are member banks of Visa U.S.A., Inc. ("Visa"). Several U.S. merchants have filed class action suits against Visa under U.S. federal antitrust law. The Corporation and its subsidiaries are not parties to these suits. However, the Corporation's banking subsidiaries, which are member banks of Visa, may be affected by these suits. The following description of the suits is based primarily on disclosures in the Quarterly Report on Form 10-Q for the period ended June 30, 2002, filed by MasterCard Incorporated ("MasterCard") with the Securities and Exchange Commission on August 14, 2002.

Commencing in October 1996, several class action suits were brought by a number of U.S. merchants against MasterCard and Visa. Those suits were later consolidated in the U.S. District Court for the Eastern District of New York. The plaintiffs challenge MasterCard's and Visa's rules requiring merchants who accept their credit cards to accept their debit cards. Plaintiffs claim that MasterCard and Visa unlawfully have tied acceptance of debit cards to acceptance of credit cards and have conspired to monopolize the point-of-sale debit card market. Plaintiffs allege that the plaintiff class has been forced to pay unlawfully high prices for debit and credit card transactions. There are related consumer class actions pending in two state courts that have been stayed pending developments in the merchants' suits. MasterCard and Visa have denied the merchants' allegations. The district court granted the plaintiffs' motion for class certification, a panel of the Second Circuit Court of Appeals affirmed, and on June 6, 2002, the U.S. Supreme Court denied MasterCard's and Visa's petition for a writ of certiorari on the issue of class certification. Recent press reports place the plaintiffs' estimated damage claims at approximately $13.0 billion to $15.0 billion, or more, before mandatory trebling under U.S. federal antitrust law. These figures reflect claims asserted and should not be construed

-49-

as an acknowledgement of the reliability of the figures presented. Trial is currently scheduled for April 2003.

The Corporation and its subsidiaries are not parties to these suits and therefore will not be directly liable for any amount related to these suits. However, if a judgment is entered against Visa, then Visa may seek to assess the associations' member banks, including the Corporation's banking subsidiaries, to obtain funds to satisfy the judgment. In addition, because a judgment against the associations could adversely affect the business operations of the member banks, they may be compelled by business necessity to assist Visa to satisfy the judgment. The outcome of these suits, the amount of any possible judgment against the associations, and the effects on the associations' member banks, including the Corporation's banking subsidiaries, resulting from these suits, cannot be determined at this time.

In addition to the above, the Corporation and its subsidiaries are subject to various pending or threatened legal proceedings, arising out of the normal course of business. In view of the inherent difficulty of predicting the outcome of such matters, the Corporation cannot state what the eventual outcome of these matters will be. However, the Corporation believes, based on current knowledge and after consultation with counsel, that the outcome of such matters will not have a material adverse effect on the Corporation's consolidated financial condition or results of operations.

ARTICLE II

MEETINGS OF STOCKHOLDERS

SECTION 1. PLACE OF MEETING. All meetings of the stockholders of this Corporation shall be held at such time and place, either within or without the State of Delaware, as shall be designated from time to time by the Board of Directors and stated in the notice of the meeting.

SECTION 2. ANNUAL MEETING OF STOCKHOLDERS. The annual meeting of stockholders shall be held on the third Friday of May of each year, if not a legal holiday, and, if a legal holiday, then on the next secular day following, at 10:00 a.m., or at such other date and time as shall be designated from time to time by the Board of Directors and stated in the notice of the meeting. At said meeting, stockholders shall elect by a plurality vote the directors to be elected at such meeting, and shall transact such other business as may properly be brought before the meeting.

SECTION 3. NOTICE OF MEETING OF STOCKHOLDERS. Written notice of every meeting of stockholders stating the place, date and hour of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given to


each stockholder entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting.

SECTION 4. LIST OF STOCKHOLDERS ENTITLED TO VOTE. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

SECTION 5. SPECIAL MEETINGS OF STOCKHOLDERS. Special meetings of the stockholders, for any purpose or purposes, unless otherwise prescribed by statute or by the Corporation's certificate of incorporation, may be called by the Chairman of the Board of Directors or, during the absence or disability of the Chairman or while that office is vacant, by the President; and shall be called by the President or Secretary at the request in writing of a majority of the Board of Directors, or at the request in writing of stockholders owning, in the aggregate, at least seventy-five percent (75%) in amount of the entire capital stock of the Corporation issued and outstanding and entitled to vote at such special meeting. Such request shall state the purpose or purposes of the proposed meeting.

SECTION 6. QUORUM OF STOCKHOLDERS. The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business, except as otherwise provided by statute or by the Corporation's certificate of incorporation. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

SECTION 7. REQUIRED VOTE. When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power, present in person or represented by proxy, shall decide any question brought before such meeting, unless the question is one upon which a different vote is required by statute, these bylaws or by the Corporation's certificate of incorporation.

2

SECTION 8. ONE VOTE PER SHARE. Unless otherwise provided in the Corporation's certificate of incorporation or in a certificate filed pursuant to Section 151(g) of the General Corporation Law of Delaware, as amended, each stockholder shall at every meeting of the stockholders be entitled to one vote, in person or by proxy, for each share of the capital stock having voting power held by such stockholder, but no proxy shall be voted after three (3) years from its date, unless the proxy provides for a longer period.

SECTION 9. NATURE OF BUSINESS. At any meeting of stockholders, only such business shall be conducted as shall have been brought before the meeting by or at the direction of the Board of Directors or by any stockholder who complies with the procedures set forth in this Section 9. No business may be transacted at any meeting of stockholders, other than business that is either:

(a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof);

(b) otherwise properly brought before such meeting of stockholders by or at the direction of the Board of Directors (or any duly authorized committee thereof); or

(c) in the case of an annual meeting of stockholders, otherwise properly brought before such meeting by any stockholder (i) who is a stockholder of record on the date of the giving of the notice provided for in this
Section 9 and on the record date for the determination of stockholders entitled to vote at such annual meeting of stockholders; and (ii) who complies with the notice procedures set forth in this Section 9.

Time of Stockholder's Notice. In addition to any other applicable requirements, such as the requirements set forth in Article III, Section 12 of the Corporation's bylaws regarding director candidate nominations, for business to be properly brought before an annual meeting of stockholders by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a stockholder's notice to the Secretary of the Corporation must be delivered to or mailed and received at the principal executive offices of the Corporation not later than the close of business on the ninetieth (90th) day nor earlier than the close of business on the one hundred twentieth (120th) day prior to the first anniversary of the immediately preceding year's annual meeting of stockholders; provided, however, that in the event that the date of the annual meeting of stockholders is more than thirty (30) days before or more than sixty (60) days after such anniversary date, notice by the stockholder in order to be timely must be so received not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth
(10th) day following the day on which public announcement of the date of such meeting of stockholders was first made. In no event shall the public announcement of an adjournment of an annual meeting commence a new time period for the giving of a stockholder's notice as described above. For purpose of this
Section 9, "public announcement" shall mean disclosure in a press release reported by the

3

Dow Jones News Service, Associated Press or comparable national news service, or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Notwithstanding anything in the second sentence of the immediately preceding paragraph to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least 100 days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice required by this bylaw shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it is delivered to the Secretary or mailed and received at the principal executive offices of the Corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation.

Form of Stockholder's Notice. To be in proper written form, a stockholder's notice to the Secretary of the Corporation must set forth as to each matter such stockholder proposes to bring before the annual meeting of stockholders: (a) a brief description of the business desired to be brought before the annual meeting of stockholders and the reasons for conducting such business at the annual meeting of stockholders; (b) the name and address of such stockholder and beneficial owner, if any, as they appear on the Corporation's books; (c) the class or series and number of shares of capital stock of the Corporation which are owned beneficially or of record by such stockholder as of the record date for the meeting (if such date shall then have been made publicly available and shall have occurred); (d) as of the date of such notice, a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business; (e) any other information which would be required to be disclosed in a proxy statement or other filings required to be made in connection with the solicitation of proxies for the proposal pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations promulgated thereunder if such stockholder were engaged in such a solicitation; and (f) a representation that such stockholder intends to appear in person or by proxy at the annual meeting of stockholders to bring such business before the meeting.

No business shall be conducted at the annual meeting of stockholders except business brought before the annual meeting of stockholders in accordance with the procedures set forth in this Section 9, provided, however, that once business has been properly brought before the annual meeting of stockholders in accordance with such procedures, nothing in this Section 9 shall be deemed to preclude discussion by any stockholder of any such business. If the Chairman of an annual meeting of stockholders determines that business was not properly brought before the annual meeting of stockholders in accordance with the foregoing procedures, the Chairman shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted. When a meeting is

4

adjourned to another time or place, notice of the adjourned meeting need not be given if the time and place thereof are announced at the meeting at which the adjournment is taken, unless the adjournment is for more than thirty (30) days, or unless after the adjournment a new record date is fixed for the adjourned meeting, in which case notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the original meeting as originally notified.

ARTICLE III

DIRECTORS

SECTION 1. POWERS. The business of the Corporation shall be managed by or under the direction of its Board of Directors, which may exercise all such powers of the Corporation and do all such lawful acts and things which are not by statute or by the Corporation's certificate of incorporation or by these bylaws directed or required to be exercised or done by the stockholders.

SECTION 6. QUORUM AND REQUIRED VOTE. At all meetings of the Board of Directors a majority of the total number of directors shall constitute a quorum for the transaction of

SECTION 7. CONSENT OF DIRECTORS IN LIEU OF MEETING. Unless otherwise restricted by the Corporation's certificate of incorporation or these bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if all members of the Board of Directors or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors or committee.

SECTION 8. COMMITTEES OF DIRECTORS.

(a) General Authority. The Board of Directors may, to the fullest extent permitted by Section 141(c)(2) of the Delaware General Corporation Law as the same may be hereinafter amended from time to time, designate one or more committees, each committee to consist of one or more of the directors of the Corporation. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members present at any meeting and not disqualified from voting, whether or not (s)he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board of Directors, or in these bylaws, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to the following matters (except as permitted by Delaware General Corporation Law as the same may be hereinafter amended from time to time): (i) approving or adopting, or recommending to the stockholders, any action or matter expressly required to be submitted to stockholders for approval; or (ii) adopting, amending or repealing any bylaw of the Corporation.

(b) Corporate Governance and Nominating Committee. The Board of Directors shall establish a Corporate Governance and Nominating Committee of the Board of Directors. The Corporate Governance and Nominating Committee may: (i) nominate candidates for election as directors of the Corporation at any meeting of stockholders called for election of directors (an "Election Meeting"); (ii) nominate candidates to fill any vacancies on the Board of Directors which may exist from time to time; and (iii) have such other powers and authority as the Board of Directors may delegate to it from time to time.

6

(c) Compensation Committee. The Board of Directors shall establish a Compensation Committee of the Board of Directors. The Compensation Committee shall have such powers and authority as the Board of Directors may delegate to it from time to time.

(d) Audit and Legal Committee. The Board of Directors shall establish an Audit and Legal Committee of the Board of Directors. The Audit and Legal Committee shall have such powers and authority as the Board of Directors may delegate to it from time to time.

SECTION 9. COMMITTEE MINUTES. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors when required.

SECTION 10. COMPENSATION OF DIRECTORS. Unless otherwise restricted by the Corporation's certificate of incorporation, the Board of Directors shall have authority to fix the compensation of directors. The directors may be paid their expenses, if any, of attendance at each meeting of the Board of Directors and may be paid a fixed sum for attendance at each meeting of the Board of Directors or a stated salary as director. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

SECTION 11. PARTICIPATION IN MEETING BY TELEPHONE OR OTHER ELECTRONIC MEDIA. Unless otherwise restricted by the Corporation's certificate of incorporation or these bylaws, members of the Board of Directors or any committee designated by the Board of Directors may participate in a meeting of the Board of Directors or committee by means of conference telephone, internet conferencing or similar communications equipment by means of which all persons participating in the meeting can hear or otherwise communicate with each other, and such participation in a meeting shall constitute presence in person at such meeting.

SECTION 12. NOMINATIONS OF DIRECTOR CANDIDATES. Only persons who are nominated in accordance with the following procedures shall be eligible for election as directors of the Corporation, except as may be otherwise provided in the Corporation's certificate of incorporation with respect to the right of directors to fill any vacancies on the Board of Directors, and the right of holders of preferred stock of the Corporation to nominate and elect a specified number of directors in certain circumstances. Nominations of persons for election to the Board of Directors may be made at any annual meeting of stockholders, or at any special meeting of stockholders called for the purpose of electing directors, and shall be made:

(a) by or at the direction of the Board of Directors (or any duly authorized committee thereof, including the Corporate Governance and Nominating Committee); or

(b) by any stockholder of the Corporation: (i) who is a stockholder of record on the date of the giving of the notice provided for in this
Section 12 and on the record date for the

7

determination of stockholders entitled to vote at such meeting; and
(ii) who complies with the notice procedures set forth in this Section 12.

In addition to any other applicable requirements, for a nomination to be made by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation. To be timely, a stockholder's notice to the Secretary of the Corporation must be delivered to or mailed and received at the principal executive offices of the Corporation:

(a) in the case of an annual meeting of stockholders, not later than the close of business on the ninetieth (90th) day nor earlier than the close of business on the one hundred twentieth (120th) day prior to the first anniversary of the immediately preceding year's annual meeting of stockholders; provided, however, that in the event that the date of the annual meeting of stockholders is more than thirty (30) days before or more than sixty (60) days after such anniversary date, notice by the stockholder in order to be timely must be so received not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting of stockholders was first made; and

(b) in the case of a special meeting of stockholders called for the purpose of electing directors, not earlier than the close of business on the one hundred twentieth (120th) day prior to such special meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of an adjournment of a special meeting commence a new time period for the giving of a stockholder's notice as described above. For purpose of this Section 12, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service, or reported in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

To be in proper written form, a stockholder's notice to the Secretary of the Corporation must set forth:

(a) as to each person whom the stockholder proposes to nominate for election as a director: (i) the name, age, business address and residence address of the person; (ii) the principal occupation or employment of the person; (iii) the class or series and number of shares of capital stock of the Corporation which are owned beneficially or of record by the person as of the record date for the meeting (if such date shall then have been made publicly available and shall have occurred) and as of the date of such

SECTION 12. INDEMNIFICATION AND INSURANCE.

(a) To the fullest extent permitted by these bylaws and by applicable law and regulation, as presently existing or hereafter amended, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that he or she is or was a director, officer or employee of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Any person who is or was an agent of the Corporation may be indemnified to the same extent as provided above. In addition, in the event any such action, suit or proceeding is threatened or instituted against a spouse to whom a director or officer is legally married at the time the director or officer is covered under the indemnification provided herein, which action, suit or proceeding arises solely out of his or her status as the spouse of a director or officer, including, without limitation, an action, suit or proceeding that seeks damages recoverable from marital community property of the director or officer and his or her spouse, property owned jointly by them or property purported to have been transferred from the director or officer to his or her spouse, then the spouse of the director or officer shall be indemnified to the same extent as provided above. At the Corporation's election, and in its sole discretion, any person who is or was the spouse of an employee or agent of the Corporation may be indemnified to the same extent as provided above. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person

13

did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, raise any inference that he or she had reasonable cause to believe that his or her conduct was unlawful.

(b) To the fullest extent permitted by these bylaws and by applicable law and regulation, as presently existing or hereafter amended, the Corporation shall indemnify any person who is or was a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor, by reason of the fact that he or she is or was a director or officer or employee of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. Any person who is or was an agent of the Corporation may be indemnified to the same extent as provided above. In addition, in the event any such action or suit is threatened or instituted against a spouse to whom a director or officer is legally married at the time the director or officer is covered under the indemnification provided herein, which action or suit arises solely out of his or her status as the spouse of a director or officer, including, without limitation, an action or suit that seeks damages recoverable from marital community property of the director or officer and his or her spouse, property owned jointly by them or property purported to have been transferred from the director or officer to his or her spouse, then the spouse of the director or officer shall be indemnified to the same extent as provided above. At the Corporation's election, and in its sole discretion, any person who is or was the spouse of an employee or agent of the Corporation may be indemnified to the same extent as provided above.

(c) To the extent that a present or former director, officer, or spouse of the director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this Section, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith.

14

(d) Any indemnification under subsections (a) and (b) of this Section (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, spouse of the director or officer, employee, agent or spouse of the employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this Section. Unless prohibited by applicable law or regulation, or otherwise required by Section 18(k) of the Federal Deposit Insurance Act, as amended, such determination shall be made with respect to a person who is a director or officer or the spouse of a director or officer at the time of the determination (a "D&O Claimant") by Independent Legal Counsel (as defined below) in a written opinion to the Board of Directors, a copy of which shall be delivered to the D&O Claimant, as follows:

1. the Disinterested Directors (as defined below) shall select Independent Legal Counsel by majority vote, even if such Disinterested Directors constitute less than a quorum, and direct that the determination be made by such counsel (or, if there are no Disinterested Directors, the full Board of Directors shall select Independent Legal Counsel by majority vote and shall direct that the determination be made by such counsel); unless there shall have occurred within two years prior to the date of the commencement of the Proceeding for which indemnification is claimed a "Change of Control" as defined in the Amended and Restated Comerica Incorporated 1997 Long-Term Incentive Plan as in effect on September 24, 2002 (or, if applicable, as in effect on such later date as determined by written agreement between the Corporation and the D&O Claimant), in which case the Independent Legal Counsel shall be selected by the D&O Claimant unless the D&O Claimant shall request that such selection be made by the Board of Directors. If it is so determined that the D&O Claimant is entitled to indemnification, payment to the D&O Claimant shall be made within 10 days after such determination.

2. the term "Disinterested Directors" shall mean directors that are not and were not parties, and who are not and were not threatened to be made parties, to such Proceeding;

3. "Independent Legal Counsel" shall mean a law firm, a member of a law firm, or an independent practitioner, that is experienced in matters of corporation law and that, under the applicable standards of professional conduct then prevailing, would not have a conflict of interest in representing either the Corporation or the D&O Claimant in an action to determine the D&O Claimant's rights under this Section.

Such determination may be made with respect to any person other than a D&O Claimant seeking indemnification under subsections (a) and (b) of this Section by the Corporation's Chairman, Chief Executive Officer, President, Vice Chairman or General Counsel, or by their designees.

(e) Expenses (including attorney's fees) incurred by an officer, director or spouse of an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Corporation in advance of the final disposition

15

of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director, officer or spouse to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this Section. Such expenses (including attorneys' fees) incurred by former directors or officers, their spouses or other employees and agents may be so paid upon such terms and conditions, if any, as the Corporation deems appropriate.

(f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this Section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or Disinterested Directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

(g) The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, spouse of a director or officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Section.

(h) For the purposes of this Section, references to "the Corporation" include, in addition to the resulting or surviving corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had the power and authority to indemnify its directors, officers, spouses of directors or officers, and employees or agents, so that any person who is or was a director, officer, spouse of a director or officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.

(i) For purposes of this Section, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the Corporation" shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries

16

of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Corporation" as referred to in this Section.

(j) The indemnification and advancement of expenses provided by, or granted pursuant to, this Section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent, and with respect to any spouse of a director or officer, shall continue following the time the director or officer spouse ceases to be a director or officer even if the marriage of the individuals terminates prior to the end of the period of coverage, and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k) The Court of Chancery shall have exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this Section or under any agreement, vote of stockholders or Disinterested Directors, or otherwise. The Court of Chancery may summarily determine the Corporation's obligation to advance expenses (including attorneys' fees).
