Slide 1:    TITLE

Bob Stockwell:

Good morning, everyone.  Thank you for joining us.

My name is Bob Stockwell and I'm the CFO of Security First Technologies.

Before we get started, I want to tell you that you can find this presentation on
our web site at www.s1.com /invest. If you have not received a faxed copy,
please call Anita Mazur at 602-614-3021.

Early this morning, we issued a press release announcing what we believe are
very exciting transactions.

As a result of this transaction, our new enterprise will focus on one of the
fastest growing segments of the emerging e-Services marketplace, providing
privately labeled financial portals to institutions around the world.

We believe that today's announcement will give the combined Company pre-eminent
leadership in this explosive market.

With me here today is Chip Mahan, the CEO of Security First Technologies, Jeff
Crowe, the President and CEO of Edify Corporation, and Michel Akkermans, the
Chairman and CEO of FICS.

Before we begin, I'd like to read this short statement: Statements in this
conference call concerning future results, performance, expectations or
intentions are forward-looking statements. Actual results, performance or
developments may differ materially from forward-looking statements as a result
of known or unknown risks, uncertainties and other factors, including those
identified in the Companies' filings with the Securities and Exchange
Commission, press releases and other public communications.

Now, I'd like to turn the call over to Chip Mahan. Chip?

Chip Mahan: Thanks, Bob.

Five years ago, S1's vision was to provide financial institutions, or FI's,
customized, on-line products that, in turn, would enable them to empower their
customers with tools to better manage their finances electronically and, in
doing so, maximize their net worth.

Internet technology, as everyone knows, has opened up vast new opportunities for
FI's and consumers. It has also attracted a new wave of competitors, who are
successfully targeting customers of banks and other FI's. FI's are looking for
ways to fight back.


   2


Slide 2:    COMMON STRATEGIC VISION

For the last several years, three companies in the e-Services industry serving
FI's, have shared a common vision.

That vision has been - and continues to be - to provide our FI clients with
technologies that not only attract, but also help them retain and expand the
scope of services they provide to their customers.

FI's, having been the target of successful competition, are rapidly embracing
this vision.

They understand the urgent need to develop online strategies as the Internet
revolution is taking shape and to find value-added ways to better serve their
customers.


   3


Slide 3:    AN INDUSTRY-DEFINING DEAL

As we were pursuing this strategic vision, two other companies in the
marketplace were pursuing it as well - two companies whose managements, products
and technological expertise I have long admired.

Therefore, I am delighted to announce today that we have signed what I consider
to be an "industry-defining deal," bringing together three companies with unique
and complementary products and services that will create the leading provider of
financial portal solutions to FI's around the world.

Let me describe each transaction:

First, S1 is acquiring the privately-held FICS Group N.V. of Brussels, Belgium,
for 20 million shares or an exchange offering valued at approximately $1.1
billion on Friday's closing price.

Through the vision of FICS's founder, Michel Akkermans, S1 is acquiring a
leading global solutions provider that already serves more than 600 FI's
worldwide, including thirty of the top 100 global banks, as well as leading
insurance companies.

In addition, we are acquiring Edify Corporation of Santa Clara, California, for
6 million shares, or $366 million, based on Friday's closing price.

Through the vision of Edify's founder, Jeff Crowe, this company has established
itself as one of the true leaders in Internet and voice e-commerce solutions to
a broad range of major FI's.

Slide 4:    REPRESENTATIVE CUSTOMERS

This slide shows you some of the impressive customers for each of the companies.


   5


Slide 5:    DREAM TEAM

Upon completion of this transaction, both Jeff Crowe and Michel Akkermans have
agreed to join me in the formation of what I call a management "dream team."

As my partners for the future, Michel will serve as S1's Chairman and President
and Jeff will serve as S1's Vice Chairman. Michel will oversee field operations,
product development and corporate marketing. Jeff will oversee corporate
strategy and development, finance and administration.

I am very excited about the prospects of this new partnership and about what I
believe we can accomplish together.

Each of us has an intimate knowledge of the marketplace and tremendous
experience in this emerging market. In addition, we are all entrepreneurs who
have served as pioneers in a new business, and, most importantly, we all share
the same vision for the future.

Slide 6: MARKET OPPORTUNITY

The market potential for the retail Internet banking space is tremendous.

According to Dove Associates, the worldwide retail Internet banking applications
market was $500 million in 1998 and is expected to grow 40 percent annually to
approximately, $2.7 billion by 2003.


   7


Slide 7:    FINANCIAL PORTAL REQUIREMENTS

Why did we decide to join together?

If you look at the portal requirements for FI's around the world, you will
understand that there are three customer markets that institutions are targeting
- - consumers, small businesses and large corporations.

Institutions also need to be able to provide access for their customers across a
broad and growing range of communication channels and devices.

Further, there are a number of capabilities required for world-class portals,
including the combination of content and personalization, as well as a number of
deployment options.


   8


Slide 8:    WHY WE CAME TOGETHER

As an independent company, S1 provided many, but not all, of the portal
requirements that FI's demand.

As you can see from the logos, the combination of S1, Edify and FICS provides
virtually all the customized portal requirements for FI's around the world.

In the world of financial portals, the ability to attract customers and to keep
them coming back is called "stickiness." By integrating these companies and our
products, we create a greater stickiness for the FI's sites. History dictates
that if a customer has two accounts with an FI, the odds of retaining that
customer is about 70% annually. However, if the customer has three accounts with
an FI, the odds of retaining that customer increases to about 97%.

As you can see by this graph, the new company's products still lacks a few
pieces like accounting, payroll, tax, mortgage and financial planning advice.
Which brings us to Intuit.


   9


Slide 9:    INTUIT ENHANCES THE OFFERING

Undoubtedly, customer attraction and retention is a critical element to success
in the financial portal marketplace.

For financial portals, there are three key applications that serve as points of
stickiness. Those three are: transaction applications (which we currently
provide), tax applications (or products like Intuit's Web TurboTax) and what we
call "Small Business In a Box."

Small Business in a Box offers small business customers a complete suite of
"back office applications" delivered over the Internet, including financial
accounting services, cash management services, and many more services we'll
discuss in the future.

Thus, to realize our full business potential, we also announced today an
agreement to strategically partner with Intuit Corporation, the world's leading
provider of personal finance, small business accounting and tax preparation
software.

Intuit enhances S1's portal services with Intuit capabilities, such as TurboTax
and Web TurboTax, QuickBooks, and financial planning and advice through
Quicken.com.

With this agreement, S1 becomes a distributor of Intuit's Web applications and
content to FI's. In addition, S1 has been given exclusive rights to create
FI-branded versions of Intuit's web-based products. This is one of the first
times that Intuit has ever done this.

This agreement provides our customers access to high-quality Intuit server-based
applications and content for private branding through the customers' portals.

Specifically, Intuit will make a $50 million equity investment in S1. Intuit has
options to purchase up to 9.9% of the new company.


   10


Slide 10:   S1: THE COMPLETE FINANCIAL PORTAL SERVICE PROVIDER

Therefore, the combination of S1, Edify and FICS - plus the investment and
business relationship with Intuit - rounds out the requirements for financial
portals.

That, in a nutshell, is the strategic rationale and business logic for this
combination.


   11


Slide 11:   THE NEW S1

By bringing these three companies together, we are creating the preferred
provider of enterprise-wide, financial portal solutions for institutions around
the world.

Now, I'd like to hand the call back over to Bob Stockwell, S1's CFO who will
provide a brief financial overview of the new company.

Bob?


   12


Slide 12:   The 'New S1' Key Facts

Bob Stockwell:

Thanks, Chip.

A few key facts illustrate why we are so excited about this new company and its
potential in this explosive growth market.

First of all, the new S1 will have a global presence, including more than 1500
employees in twelve countries on four continents. We will also have a
significant presence in Silicon Valley.

The combined Company has customers in 26 countries, including 36 of the top 100
global FI's and 26 of the top 50 banks in the United States.


   13


Slide 13:   STRONG BASE OF FINANCIAL PARTNERS

Bob Stockwell (continues):

In addition, we have industry-leading partners, include such prestigious names
as Andersen Consulting, ACI, BroadVision, Hewlett-Packard and IBM.


   14


Slide 14:   THE NEW S1 - Pro Forma

Bob Stockwell (continues):

I would like to briefly review the powerful financial picture for the combined
organizations.

On a pro forma basis, in the first quarter 1999 the combined entity generated
approximately $43 million in revenues. As we look beyond 1999, we will be moving
the company away from the traditional software revenue model of up front license
fees and ongoing maintenance fees, towards a recurring revenue model that has
driven S1's growth to date.

Central to establishing recurring revenues will be our ability to host many of
our new product offerings in S1's data center. Also, we anticipate that we will
establish recurring revenue steams from those customers who choose to run our
products themselves based upon per customer per month fees on direct licenses.

As Chip noted earlier, the new Company will have products that cross the
spectrum of the financial portal model. We will incorporate the retail, small
business and corporate banking products into S1's data center solution. Further,
we will now be able to offer a full product line to those FI's that desire to
run the technology themselves.

During the transition period to a deferred revenue stream, we anticipate that
growth in revenues will moderate in the year 2000.

Looking beyond the year 2000, as the deferred revenues begin to build up
momentum, we are anticipating that overall revenue growth will all begin to
accelerate in line with industry growth.

We, as a team, believe that a move towards establishing deferred revenue model
across the entire organization will create the greatest amount of shareholder
value. As I just noted, during the transition period, there is a short-term
impact on the growth of revenues.

However, this brief slowing of revenue growth combined with the additional
investment required in research and development to bring our powerful technology
platforms together, will result in the entire company reaching a neutral cash
flow position in the latter part of the year 2000.

The acquisitions will be accounted for as purchased and S1 will record a
goodwill charge of approximately $1.3 billion, which will be amortized over the
next several years. The goodwill charge, along with the $200 million charge for
the option granted to Intuit will result in significant non-cash charges in
future income statements.


   15

However, as in the past, the combined management team will continue to focus on
generating cash and cash per share.

On a pro-forma basis, upon closing the transactions in the fourth quarter, the
combined entity will have approximately $100 million in cash available to fund
operations. This amount should provide adequate funding for the organization
until we reach the cash flow neutral milestone in 2000.

Now I'd like to turn it back over to Chip Mahan. Chip?


   16


Slide 15:   JEFF CROWE - PRESIDENT AND CEO [Edify Logo]

Chip Mahan:

Thanks again, Bob.

Before Jeff says a few words about his company, let me say that no other
domestic company has impressed us as much as Edify, which is personified by
its founder, President and CEO Jeff Crowe.

Jeff and I have shared the same goals and objectives for many years and have
concluded that it's in the best interests of both companies to combine forces
rather than compete separately.

I look forward to his counsel, his insights and his high intellect as we pursue
new business strategies together.

Jeff...


   17


Slide 16:   EDIFY SNAPSHOT

Jeff Crowe: 

Thanks, Chip. I'm really excited about this being the first unofficial day of
working together. I'm looking forward to a long and productive partnership.

It's been clear to me that our visions are very well aligned. Together, we can
approach the market more effectively and efficiently - and achieve together more
than we would separately - making this a 1 + 1 + 1 = 5 deal.

I'm also excited about the role of FICS, which builds on my own goals of driving
the online banking revolution globally.

For those of you who do not follow Edify, let me spell out for you what we bring
to the table in this transaction. Edify is a leading provider of Internet and
voice e-commerce solutions that's been in business over 8 years.

We've built a substantial base of customers including ANZ Bank, Chase Manhattan
Bank, Safeco, and over 300 other FI's. Additionally, we have a total of over
1250 corporate customers including many other household names like Home Shopping
Network, MCI, Sears and Sprint.

We've got 470 employees, revenues over $70M, and leading market positions in the
Internet banking and voice e-commerce markets.

We've also brought out the first products to market in the emerging areas of
business Internet banking and electronic bill presentment.

Our strengths are highly complementary those of to S1 and FICS. When we combine
the best of these companies together, we will have a very strong position to
approach the market for financial portals.

Chip?


   18


Slide 17:   MICHEL AKKERMANS - CEO AND CHAIRMAN [FICS Logo]

Chip Mahan: Thanks, Jeff.

As S1 pursued what can best be described as a domestic strategy, we consistently
had our eyes on the world. Few, if any, competitors understand the financial
service landscape and their business requirements for the 21st century as well
as one of the true entrepreneurs of the industry today, Michel Akkermans.

Ever since meeting Michel, I have been truly impressed with his keen management
abilities and the success he has had in not only penetrating the international
markets, but also beginning to make a major footprint here in the U.S.

Michel will play an integral role in the senior management team we are
assembling here at S1 and I am glad to welcome him as my new partner and friend.

Michel...


   19


Slide 18:   FICS SNAPSHOT

Michel Akkermans: 

Thanks, Chip.

I am very excited about the combination of these three fine companies and I am
delighted to partner with two leaders in this new industry - Chip Mahan and Jeff
Crowe.

In this three-way transaction, my Company - FICS - really brings the new S1 a
global perspective, which is increasingly important as Internet banking and
online financial services rapidly become a global industry.

Let me tell you a little bit about FICS.

The Company was founded in 1989 with the express vision of focusing on FI's. We
are a global information technologies company that has grown rapidly over the
last ten years. Last year, our revenues totaled more than $55 million and we now
have more than 650 employees in ten countries around the globe.

We are a world leader in our two core areas - Financial Reporting Services and
Electronic Services Delivery.

In Electronic Services Delivery, we provide financial electronic commerce
solutions across a range of technologies and devices that link FI's both
internationally and in the U.S. with their customers.

In the Financial Reporting Systems area, we provide software products and
services that enable banks around the world to interface with their regulators.

I believe that the combination of these three companies will create a global
leader in the rapidly growing Internet banking market, and I am thrilled to be a
part of it.

Chip...


   20


Slide 19:   GLOBAL INTEGRATION STRATEGY

Chip Mahan:

Thank you, Michel.

I'm sure many of you are now asking how these three companies will be integrated
and how we will communicate that to the marketplace.

Let me tell you that we are focused on this issue.

In short, the principles guiding our integration strategy are these: We will be
decisive, move fast and go deep.

Our integration team leaders are in place. Additionally, valued partners such as
Andersen Consulting, ACI, Broadvision, HP and IBM, will be available to assist
us in this integration in order to maintain our high level of customer focus.

The key areas we are focused on are:

- -    Products and platforms
- -    Sales
- -    Services
- -    Finance and Administration

The integration execution plan will be complete at the time of the transaction's
closing. We will update you on a regular basis about the progress of those
plans.

   21


Slide 20:   SUMMARY

So, in summary:

1. We are creating a uniquely positioned, leading provider of enterprise-wide
financial portal solutions to institutions worldwide.

2. By doing this, we will become the preferred choice for FI's around the world
in providing their clients online financial services.

3. We are excited by the tremendous growth potential this industry has to offer
and will aggressively pursue it.

4. The $50 million equity investment by Intuit is a "win-win" for us and our
banking customers and will significantly complement other business
relationships.

5. And, finally, when this transaction is completed, we intend to name the new
company S1 Corporation and will brand that name in the marketplace.

As you can see, we are very excited about this business combination. And now,
we're ready to take your questions.
