<Page> Exhibit 99(a) [CITYNATIONAL CORPORATION LETTERHEAD] CONTACTS: CITY NATIONAL CORPORATION Frank Pekny 310/888-6700 (Financial/Investors) Cary Walker 213/833-4715 (Media) Ian Campbell / Abernathy MacGregor Group 213-630-6550 CIVIC BANCORP Herbert C. Foster 510/836-6500 FOR IMMEDIATE RELEASE CITY NATIONAL CORPORATON TO ACQUIRE CIVIC BANCORP, DOUBLING ITS ASSETS IN BAY AREA CIVIC'S MANAGEMENT TEAM TO REMAIN WITH CITY NATIONAL LOS ANGELES, November 19, 2001 -- City National Corporation (NYSE: CYN), parent company of City National Bank, and Civic BanCorp (NASDAQ: CIVC), parent of CivicBank of Commerce, today announced a definitive agreement for the acquisition of Civic by City National in a transaction currently valued at $113 million in cash and stock. Civic is one of the Bay Area's leading independent business banks, with offices throughout the East Bay and assets of $510 million, loans of $375 million and deposits of $443 million as of September 30, 2001. <Page> CITY NATIONAL CORPORATION TO ACQUIRE CIVIC BANCORP, DOUBLING ITS ASSETS IN BAY AREA Assuming the transaction closes in the first quarter of 2002, and excluding any revenue enhancements, City National expects the transaction to be accretive to its GAAP and cash earnings per share in 2002. "We are very pleased that Civic's talented management team and outstanding clients and shareholders will be joining City National," said City National CEO Russell Goldsmith. "During the last two years, City National Bank has steadily expanded in the San Francisco Bay Area, and this combination will bring our Bay Area assets to $1 billion while extending our platform for growth in a measured and focused way in the world's 18th largest economy. "Civic's clear identity as a commercial bank, primarily in the East Bay, strongly complements our private and business banking presence on the Peninsula and our new commercial banking center in Walnut Creek," Goldsmith added. Herbert C. Foster, Civic's President and Chief Executive Officer, who will join City National as its Northern California East Bay Area Executive, said: "This is an excellent fit of two relationship-based banks. The combination of Civic with California's premier private and business bank will allow our clients to continue their established relationships with our bankers - while giving them access to an even broader array of financial products, services and capabilities. We are optimistic that these broader capabilities will enable us to do more for our clients and to win a greater share of their business." <Page> CITY NATIONAL CORPORATION TO ACQUIRE CIVIC BANCORP, DOUBLING ITS ASSETS IN BAY AREA TERMS OF THE TRANSACTION Under terms of the agreement, each of the 5.3 million shares of Civic stock will be exchanged - at each shareholder's election - either for cash of $20.25 per share or for an amount of City National stock based on the average per share price of City National common stock for a 10-day trading period immediately prior to the closing. If this average price of City National stock is (1) between $37.56 - and $50.82 per share, each share of Civic stock may be exchanged for 0.4582 of a share of City National stock, (2) less than $37.56 per share, the exchange ratio will equal $17.21 divided by the average price of City National stock, and (3) greater than $50.82, the exchange ratio will equal $23.29 divided by the average price of City National stock. Since each Civic shareholder may elect to receive cash, stock or a combination of both, these elections may have to be pro-rated to ensure that between 47% and 53.5% of the total consideration is paid in City National stock. City National common stock received by Civic shareholders is expected to qualify as a tax-free exchange. The completion of the transaction is subject to regulatory and Civic shareholder approval. The two companies' boards of directors have approved the transaction.
