New Company to Accelerate Delivery of Financial Portal Solutions to Financial

Security First Technologies (NASDAQ:SONE - news), a premier provider of
Internet-based applications for the financial services industry, today announced
that it has agreed to join forces with FICS and Edify to create the preeminent
provider of transactional financial portal solutions for financial institutions
worldwide.

Under the agreement, a Security First Technologies' Belgian subsidiary will
acquire FICS Group N.V., a privately held company based in Brussels, Belgium. In
addition, Security First Technologies has agreed to acquire Edify Corporation
(NASDAQ:EDFY - news) of Santa Clara, California.

In connection with the FICS transaction, Security First Technologies will issue
20 million shares of its stock. In the Edify transaction, Security First
Technologies and Edify have agreed to a fixed exchange ratio whereby Security
First Technologies will issue 0.330969 shares for each share of Edify stock or
approximately 6.4 million shares in total. Based on Security First Technologies'
closing price of US$54.00 on May 14, 1999, the value of the FICS transaction is
approximately US$1.08 billion, and the value of the Edify transaction is
approximately US$345 million.

James S. Mahan III, Security First Technologies' chief executive officer,
commented, "By combining these three organizations, we are creating the world's
most complete financial portal solutions provider that is well positioned to
take advantage of the explosive growth of the online financial services market.
This strategic business combination will be the catalyst for accelerating the
e-commerce revolution and propelling the value of financial portal capabilities
throughout the financial services industry."

Collectively, the new organization will deliver a complete set of solutions that
span a financial institution's enterprise, from consumer banking, brokerage and
insurance applications to small business and corporate electronic banking
products to financial reporting solutions. These applications can be delivered
across multiple access devices and channels, such as Internet, wireless, and

ADDITIONAL TERMS OF THE AGREEMENT

The corporate headquarters for the new company will be in Atlanta, Georgia, with
major operational centers in Brussels, Belgium and Santa Clara, California. As
soon as the acquisitions are complete, the three organizations will be combined
under the name of S1 Corporation. Mahan will remain CEO of S1. Michel Akkermans,
FICS's founder, CEO and Chairman of the Board, will serve as President and
manage field operations, product strategy, product development, and corporate
marketing. Jeffrey Crowe, Edify's CEO and President, will be responsible for
corporate development strategy, finance and administration. Both Akkermans and
Crowe will join the S1 Board of Directors, with Akkermans named as Chairman and
Crowe as Vice Chairman. The transactions, both of which will be accounted for on
a purchase accounting basis, are expected to be completed in the fourth quarter
of 1999. Both transactions are subject to customary regulatory filings and
Security First Technologies' shareholder approval. The Edify transaction also is
subject to approval by Edify shareholders. The acquisition of FICS by the
Belgian subsidiary of S1 is also subject to the subsidiary obtaining financing
for the acquisition.

STRENGTHS OF THE NEW ORGANIZATION

The worldwide retail Internet banking applications market was US$500 million in
1998 and is expected to grow 40 percent annually to approximately, US$2.7
billion by 2003, according to Dove Associates, a Boston-based international
management consulting firm. The companies expect that the combined organization
will accelerate this growth and industry expansion.

According to Akkermans, "Together, the new organization will consist of the most
comprehensive set of resources available, including a combined total of more
than 400 developers, more than 600 implementation professionals, and more than
US$50 million in R&D investments on an annual basis. This powerful combination
will give financial institutions a more

robust, turn-key financial portal solution with outsourcing options for greater
cost efficiency and faster time to market, as well as a wide portfolio of
additional software products and services." Shortly after completion of the
acquisitions, customers of the new organization will begin realizing key
benefits, including new product availability, services for new market segments
and data center hosting capabilities. While the long-term strategy of the new
organization will be to converge to common technology, there are several points
of integration that will be made possible immediately through the existing S1
Data Center in the U.S.

According to Crowe, "This powerful combination will enable us to create world
class financial portal solutions, incorporating transactional capabilities,
content and one-to-one marketing. We will be unique in our ability to deliver
additional functionality that helps our financial institutions enhance customer
retention, increase revenue opportunities and create new competitive
advantages."
