                   BANKBOSTON ANNOUNCES AGREEMENT TO PURCHASE
                       ROBERTSON STEPHENS FROM BANKAMERICA
               --A Compelling Combination for Corporate Clients--

         BOSTON, MA, May 29, 1998 -- BankBoston Corporation (NYSE: BKB)
announced today it has reached an agreement to acquire the investment banking
operations of Robertson Stephens from BankAmerica Corporation. Under the terms
of the agreement, BankBoston will pay $400 million in cash to BankAmerica and
will establish a retention pool of approximately $400 million, consisting of
$300 million in cash to be paid over four years and $100 million of stock
options granted at market price upon close of the transaction. The after-tax
present value of the transaction is estimated to be approximately $550 million.
The transaction is subject to approvals by regulators and is expected to close
in the fourth quarter of 1998.

         "Robertson Stephens is a great fit for BankBoston," said BankBoston
Chairman and CEO Chad Gifford. "The addition of Robertson Stephens' equity
origination, distribution and research capabilities to our existing investment
banking and capital markets business allows us to offer a full range of
investment banking services to all of our corporate customers worldwide. We also
share a common commitment toward managing

                                    - more -




for value, focusing our resources on those industries which show the highest
potential for growth. Finally, our cultures are remarkably compatible and there
is little, if any, overlap between the two organizations." 

         Gifford said that he is particularly pleased that BankBoston's new
colleagues at Robertson Stephens accepted $100 million of future value in the
form of stock options, which aligns their interests with those of BankBoston's
shareholders. 

         "Of all the potential partners we met with, BankBoston most closely
reflects our specialized industry focus and growth strategy," said Robertson
Stephens President and Chief Executive Officer Mike McCaffery. "As part of
BankBoston's organization, we will have the international infrastructure to
serve corporate clients from the U.S. to Latin America and beyond as they expand
their business across borders and BankBoston's expertise with high yield debt,
loan syndications and traditional lending should prove to be particularly
valuable to our client base. At the same time, our equity distribution and
research expertise will be valuable to many of BankBoston's customers who have
expressed interest in this capability." 

         "As a combined organization, we will leverage what we know from decades
of relationship banking in specialized industries such as technology, media and
communications, healthcare, real estate, and consumer and retail -- to offer the
full complement of financial products, advisory services, and industry
expertise," said BankBoston Vice Chairman Paul Hogan. "BankBoston's customer
base has demonstrated extensive use of capital markets products and has
benefited from our existing strength in loan syndications, high yield debt
underwriting, and leveraged financing. The missing 

                                 - more -

                                    2



piece has been equity underwriting. With Robertson Stephens as part of our
organization, we are well poised to be the preferred provider of financial
services to our combined target
client base."

         Robertson Stephens' operations will continue to be headquartered in San
Francisco, and President and Chief Executive Officer Mike McCaffery will
continue to manage the day-to-day operations of the company, reporting to
BankBoston Vice Chairman Paul Hogan. More than 140 of the top managers,
principals, and managing directors of BancAmerica Robertson Stephens, including
all department heads, have entered into employment agreements with BankBoston
pending closing of the transaction. BankBoston is extremely pleased with the
support it has received from the key professionals of BancAmerica Robertson
Stephens.

         Sanford Robertson, the 67-year old founder and chairman of Robertson
Stephens has decided not to be employed by the new organization. "We are
grateful to Sandy for his efforts in building this very strong and recognized
firm," said BankBoston President and COO Henrique Meirelles.

         "BancBoston Robertson Stephens is a great combination that complements
both firms' strengths," said Robertson. "I wish my colleagues and BankBoston
well in their new partnership, which undoubtedly will be successful."

         Robertson has a non-competition agreement with BancAmerica Robertson
Stephens running through December, 2000.
