Bank of America and FleetBoston Financial to Create

Nation’s Premier Financial Services Company

Bank of America Corporation and FleetBoston Financial Corporation today announced a definitive agreement to merge, creating the nation’s premier financial services company. The company will bring unmatched convenience, innovation and resources to customers and clients throughout the nation and around the world.

The merger, to be accomplished through a stock-for-stock transaction, establishes a new Bank of America that will serve approximately 33 million consumer relationships, with leading market shares throughout the Northeast, Southeast, Midwest, Southwest and West regions of the United States.

The company will provide market-leading products for 2.5 million business clients in the United States and 34 other countries, backed by the capital power of the second largest banking company in the world. The new Bank of America will have $68 billion in shareholders’ equity and the two companies have generated $10 billion in earnings in the first nine months of 2003.

Charles K. Gifford, currently chairman and chief executive officer of FleetBoston, will be chairman of the board of directors of the merged company from Boston. Kenneth D. Lewis, currently chairman and chief executive officer of Bank of America, will be chief executive officer and will maintain his principal office in the combined company’s headquarters in Charlotte.

“This merger is about delivering the combined capabilities of two powerful organizations to our customers, shareholders and communities,” Lewis said. “Customers will benefit from the most extensive retail franchise in the nation, a shared commitment to service excellence, and a full range of traditional and innovative financial products and services. Shareholders will benefit from the best retail and wealth markets in America, unmatched diversity of revenues and resources, and the most talented management team in the industry. Our communities will benefit from our shared tradition of public-private partnership, community development and philanthropic investment.

“The opportunity to merge with Fleet is unique,” Lewis continued. “From the Bank of America perspective, we will have the leading market position in Massachusetts, Rhode Island, Connecticut and New Jersey as well as a powerful retail platform in New York City, upstate New York, New Hampshire and Maine. From a broader perspective, we are building a company that will deliver more financial service capabilities to more Americans than ever before in our nation’s history.

“We are proud to join forces in these new markets and will continue to be a large employer and committed corporate citizen in New England, as we have in the other regions of the country where we do business,” Lewis continued. “In that regard, wealth management, leasing, Latin America, asset-based lending, small business and premier banking will be based in Boston.

“I am especially looking forward to working with Chad Gifford, for whom I have had a high regard over the years. Chad’s strategic thinking based on his years of success and experience will be invaluable for me as we partner on customer, employee, values, philanthropic and strategic issues.”

“This combination will bring added convenience and resources to Fleet customers throughout the Northeast,” Gifford said. “We decided that Bank of America provided the perfect complement to our franchise for our customers. We are also impressed that they shared Fleet’s commitment to philanthropy and community development. Together, our companies should be the unchallenged leaders in these endeavors within our industry.”

Gifford continued, “While Fleet has established leading market shares in New England and the Northeast, Bank of America has similar positions in the South, West and Midwest. Together, these two companies will clearly be the number one financial services provider for consumers and businesses of all sizes with market-leading product and geographic capabilities.”

Strong market positions in all customer segments

The new Bank of America will be America’s best banking franchise with unrivaled retail distribution in the most attractive markets. The company will have 9.8 percent of the banking deposits in the United States and have the first, second or third largest market shares in 21 of the 29 states in its retail footprint, including significant market shares in 21 of the nation’s 30 largest metropolitan areas. Bank of America will be first, second or third in market share in 23 of the 30 fastest growing metropolitan areas.

It will feature the most extensive and convenient delivery network through almost 5,700 retail banking offices, more than 16,500 ATMs, award-winning online and electronic bill pay services and 24-hour telephone banking.

In addition to being America’s largest consumer bank, the new Bank of America will be the number one lender to small banking businesses in the United States.

And it will have the largest share of middle market and large corporate relationships, including more than 95 percent of the Fortune 500. The company will be number one in providing domestic and global cash management services, with 16,000 business and institutional clients. It also has a growing investment bank that has been steadily gaining market share.

With $470 billion in assets under management, the wealth management business will be the ninth largest in the country. While the wealth management business will be based in Boston, key leadership will be in both Boston and New York.

Both Bank of America and FleetBoston Financial have used Six Sigma successfully in recent years to streamline processes, improve quality, efficiency and accuracy, and to free up capital for strategic investment. The leadership team of the newly combined company is committed to continuing the Six Sigma program in all areas of the business.
