Notes to Financial Statements December 31, 1997 and 1996 1. Significant Accounting Policies The financial statements of the 1991 Thrift Incentive Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc. (the Plan) are presented on the accrual basis of accounting. Participating entities include: Cullen/Frost Bankers, Inc. (CFBI); Frost National Bank; and United States National Bank, all of which are referred to herein as "the Company." The cost of a specific security sold is used to compute gains and losses on the sale of investments. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 2. Description of the Plan The Plan, amended and restated on January 1, 1991, is a nonqualified contributory plan. In addition to the Plan, the Company maintains the 401(k) Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc. and its Affiliates (the 401(k) Plan). The Plan covers substantially all eligible employees who have been determined to be highly compensated employees with respect to the plan year under the provisions of the 401(k) Plan regarding discretionary matching contributions, and who have been designated by the Plan's administrative committee as eligible for participation. The Plan was adopted to offer to eligible employees whose participation in the 401(k) Plan is limited an alternative means of receiving comparable benefits. For each plan year, each active participant is eligible to contribute an amount not to exceed the total of: i) the amount by which the active participant's 401(k) Plan contributions have been limited by IRS regulations not to exceed the difference between 4 a) six percent of the participant's compensation for the respective plan year, and 5 1991 Thrift Incentive Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc. Notes to Financial Statements (continued) December 31, 1997 and 1996 2. Description of the Plan (continued) b) the total before- and after-tax contributions allocated under the 401(k) Plan, and ii) the amount by which the participant's contributions to the 401(k) Plan have been limited by IRS regulations. For each plan year, the Company makes contributions equal to 100% of the participants' before- and after-tax contributions to the Plan and the 401(k) Plan, up to six percent of the participants' compensation for the respective plan year. Participants are immediately vested 100% in their accounts which are distributed to them as of the date the distribution is made. With respect to each plan year, all contributions under the Plan, from both the participants and the Company, are invested in common stock of CFBI. All assets of the Plan are distributed on an annual basis by the end of each plan year. Participants receive stock certificates for their allocated portion of CFBI common stock (in whole shares), and cash for fractional shares. 3. Transactions With Parties-in-Interest The Company may pay for certain or all expenses incurred in administering the provisions of the Plan. During 1997 and 1996, all such expenses were paid by the Company. 4. Income Tax Status The Plan is not subject to federal income taxes. 6 1991 Thrift Incentive Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc. Notes to Financial Statements (continued) December 31, 1997 and 1996 5. Impact of Year 2000 (Unaudited) The Year 2000 issue is the result of computer programs having been written using two digits rather than four to define the applicable year. Any of the Plan's computer programs, including programs from outside vendors, that have time-sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a system failure or miscalculations causing disruptions of operations including, among other things, a temporary inability to process transactions. Management of Frost National Bank, trustee, has completed an assessment and will work with its third-party vendor to modify or replace portions of its software so that its computer systems will function properly with respect to dates in the year 2000 and thereafter. Costs of Year 2000 compliance are borne by Frost National Bank and not the Plan. 7 EXHIBIT 19.2 The Financial Statements and Supplemental Schedules for the 401(k) Stock Purchase Plan for Employees of Cullen/Frost Bankers, Inc.

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 1997 and 1996, and the changes in its net assets available for benefits for the years then ended, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedules of assets held for investment purposes as of December 31, 1997 and reportable transactions for the year then ended are presented for purposes of complying with the Department of Labor's Compensation and Benefits Committee of the 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, and are not a required part of the financial statements. The supplemental schedules have been subjected to the auditing procedures applied in our audit of the 1997 financial statements and, in our opinion, are fairly stated in all material respects in relation to the 1997 financial statements taken as a whole. The schedule of assets held for investment purposes that accompanies the Plan's financial statements does not disclose the historical cost of certain plan assets held by the plan trustee. Disclosure of this information is required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. /s/Ernst & Young LLP -------------------- Ernst & Young LLP San Antonio, Texas June 23, 1998 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates Statements of Net Assets Available for Benefits December 31 1997 1996 -------------------- Assets Common stock of Cullen/Frost Bankers, Inc.

Significant Accounting Policies The accounting records of the 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates (the Plan) are maintained on the accrual basis of accounting. The Plan's investments are held in common stock of Cullen/Frost Bankers, Inc. (CFBI), AIM LTD Maturity Treasury Fund, Templeton Growth Fund, Fidelity Advisor Growth Opportunities Fund, and Optimum Mix/Total Return Portfolio, and Short- Term Investments Co. Prime Portfolio, which are stated at fair value based on quoted market prices on the valuation date, and in a money market fund. Changes in fair market value and gains and losses on the sale of investment securities are reflected in the statements of changes in net assets available for benefits as net appreciation in fair value of investments. Money market investments are valued at cost, which approximates fair value. Administrative expenses of the Plan are paid by CFBI. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 2. Description of the Plan The following is a general description of the Plan. Participants should refer to the plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan qualified under Section 401(a) of the Internal Revenue Code (IRC) and covers full-time employees who complete 90 days of service and part-time employees who complete 90 days of service and are scheduled to work more than 1,000 hours in a year. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates Notes to Financial Statements (continued) December 31, 1997 and 1996 2. Description of the Plan (continued) Contributions and Investment Options Participants may contribute an amount not less than 2% and not exceeding 16% of their compensation, limited by 401(k) regulations, and may direct investments of their accounts in either common stock of CFBI, AIM Short-Term Prime Money Market Fund, AIM LTD Maturity Treasury Fund, Templeton Growth Fund, Fidelity Advisor Growth Opportunities Fund, Fidelity Money Market Fund, or Optimum Mix/Total Return Portfolio, or Short-Term Investments Co. Prime Portfolio. Participants are able to invest their contributions in these funds in 1% increments. CFBI matches 100% of the participants' contributions up to 6% of the participants' compensation. Participant Accounts Each participant's account is credited with the participant's contributions and allocations of (a) the Company's contributions and (b) plan earnings. Forfeited balances of terminated participants' nonvested accounts are used to restore forfeitures of reemployed participants, pay administrative expenses, or reduce future company contributions. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. Vesting Participants are immediately vested in their voluntary contributions plus actual earnings thereon. Participants employed prior to January 1, 1991 are 100% vested in their employer contributions. Participants employed after December 31, 1990 vest in their employer contributions at 20% per year with 100% vesting occurring after completion of five years of service, upon death or disability, or when the participant reaches age 65. Participant Loans Participants may borrow from their fund accounts a minimum of $500 up to a maximum of $50,000 or 50% of their account balance, reduced by the highest amount of any loan outstanding within the previous twelve months. Loan transactions are treated as a transfer from (to) the investment fund to (from) the loan fund. Loan terms range from 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates Notes to Financial Statements (continued) December 31, 1997 and 1996 2. Description of the Plan (continued) 1 to 5 years or up to 30 years for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates as determined quarterly by the plan administrator. Principal and interest are paid ratably through semimonthly payroll deductions. Subject to Internal Revenue Service (IRS) limitations, participants may make hardship withdrawals from a portion of their 401(k) contributions to pay for an immediate and heavy financial need. Payment of Benefits Upon normal retirement at age 65, or in the event of death or disability, a participant will receive a lump-sum payment of his (her) account in the Plan and all amounts which have been allocated to his (her) plan account. Distribution of a participant's account must occur no later than April of the calendar year after the participant reaches age 70 1/2. In the event of termination of employment with the employer for any other reason, the participant is entitled to the vested portion of his (her) account in the Plan and all vested amounts which have been allocated to his (her) plan account. Plan Termination Although it has not expressed any intent to do so, CFBI has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants will become 100% vested in their accounts. 3. Benefits Payable to Terminated Participants At December 31, 1997, there were nine terminated participants in the Plan entitled to aggregate vested benefits totaling $82,411 in cash disbursements and 5,211 shares of CFBI common stock, or $316,256, applying the fair market value of the stock of $60.69 per share at December 31, 1997. At December 31, 1996, there were ten terminated participants in the Plan entitled to aggregate vested benefits totaling $27,961 in cash distributions and 9,479 shares of CFBI common stock, or $315,177, applying the fair market value of the stock of $33.25 per share at December 31, 1996. 401(k) Stock Purchase Plan for the Employees of Cullen/Frost Bankers, Inc. and Its Affiliates Notes to Financial Statements (continued) December 31, 1997 and 1996 4.

The Plan has been amended since receiving the determination letter. However, the plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 6. Plan Merger Effective December 31, 1997, the Citizens State Bank of Corpus Christi Employees' 401(k) Profit Sharing Plan (CSB) was merged into the Plan.
