PART I

ITEM 1. BUSINESS.

You should consider carefully the following risks. If any of the following
risks actually occur, our business, financial condition or results of operations
would likely suffer.

WE DO NOT EXPECT TO ACHIEVE PROFITABLE OPERATIONS FOR THE FORESEEABLE FUTURE AND
THIS MAY NEGATIVELY IMPACT THE VALUE OF OUR COMMON STOCK

We incurred losses in 1999 and we expect to incur losses in 2000. At
December 31, 1999, we had an accumulated deficit of $207.9 million. In addition,
as a result of our recent acquisitions, we recorded approximately $928.7 million
of goodwill and other intangible assets, resulting in amortization expense of
approximately $306.8 million annually over approximately three years. Moreover,
we expect that our expenses associated with sales, marketing, research and
development, customer support and executive offices will continue to increase
over the near term, even though revenues may not keep pace with these expenses.
As a result, we expect to continue to incur net losses for the foreseeable
future.

Our future operating results will be adversely affected if, among other
things:

- there is insufficient demand for our products;

- we are unsuccessful in attracting and retaining motivated and qualified
personnel; or

- the amount of price and product competition we face increases as a result
of the growth of financial services activity on the Internet.

ACQUISITIONS MAY BE COSTLY AND DIFFICULT TO INTEGRATE, DIVERT MANAGEMENT
RESOURCES OR DILUTE STOCKHOLDER VALUE

We acquired three companies in November 1999 and have signed agreements to
acquire two additional companies since then. Integrating these companies and any
future acquisitions into our existing operations is a complex, time-consuming
and expensive process and may disrupt our business if not completed in a timely
and efficient manner. We may encounter substantial difficulties, costs and
delays in integrating acquired operations with our own, including:

- potential incompatibility of business cultures;

- potential delays in rationalizing diverse technology platforms;

- potential difficulties in coordinating geographically separated
organizations;

- potential difficulties in re-training sales forces to market all of our
products across all of our intended markets;

- potential conflicts in third-party relationships; and

- the loss of key employees and diversion of the attention of management
from other ongoing business concerns.

In addition, we intend to continue to pursue acquisition or investment
opportunities in the future, which could cause us to:

- issue additional shares of our stock, which would dilute our current
stockholders' percentage ownership;

- incur debt and assume liabilities; and

- incur amortization expenses related to goodwill and other intangible
assets or incur large and immediate write-offs.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE AND ANY FLUCTUATIONS COULD
ADVERSELY AFFECT THE PRICE OF OUR COMMON STOCK

Our quarterly operating results have fluctuated significantly to date. If
we fail to meet the expectations of securities analysts or investors as a result
of any future fluctuations in our quarterly operating results, the market price
of our common stock would likely decline. We expect that we may experience
fluctuations in future quarters because:

- we cannot accurately predict the number and timing of contracts we will
sign in a period, in part because the budget constraints and internal
review processes of existing and potential clients are not within our
control;

- our clients' orders tend to be relatively large, and in any given period
a substantial portion of our revenues may be attributable to a few
clients;

- the length of our sales cycle to large financial organizations generally
lasts from six to 18 months, which adds an element of uncertainty to our
ability to forecast revenues;

- if we fail to introduce new or enhanced products, or if our competitors
introduce new or enhanced products, sales of our products and services
may not achieve expected levels and may even decline;

- our ability to expand the mix of distribution channels through which our
products are sold may be limited;

- our products may not achieve widespread consumer acceptance, which could
cause our revenues to be lower than expected;

- our sales may be constrained by the timing of releases of third-party
software that works with our products; and

- a significant percentage of our expenses is relatively fixed, and we may
be unable to reduce expenses if revenues decrease.

WE DEPEND ON A LIMITED NUMBER OF CLIENTS FOR MOST OF OUR REVENUE AND, IF ANY OF
THOSE CLIENTS TERMINATES ITS CONTRACT, OUR REVENUES AND FINANCIAL PERFORMANCE
WOULD DECLINE

Our business success depends on our relationships with a limited number of
large clients. On a pro forma basis giving effect to our recent acquisitions of
Edify Corporation, FICS Group N.V. and VerticalOne Corporation as if the
transactions occurred on January 1, 1999, we had one client which accounted for
our 21% of our revenue for 1999. We expect that we will continue to derive a
significant portion of our revenue from a limited number of clients in the
future.

A substantial number of our client contracts do not allow our clients to
terminate their contracts prior to the termination date without financial
penalties. These financial penalties are usually insufficient to replace the
ongoing revenue we would have otherwise received.

SYSTEM FAILURES OR PERFORMANCE PROBLEMS WITH OUR PRODUCTS COULD CAUSE DEMAND FOR
THESE PRODUCTS TO DECREASE, REQUIRE US TO MAKE SIGNIFICANT CAPITAL EXPENDITURES
OR IMPAIR CLIENT RELATIONS

There are many factors which could adversely affect the performance,
quality and desirability of our products and could delay or prevent these
products from gaining market acceptance. These factors include:

- extraordinary end-user volumes or other events could cause systems to
fail or to operate at an unacceptably low speed, causing transaction
delays for end users;

- our products could contain errors, or "bugs", which could impair the
services we provide;

- during the initial implementation of some products, we experienced
significant delays integrating software and bringing banks online, and we
may experience similar difficulties or delays in connection with future
implementations and upgrades to new versions;

2
4

- many of our products require integration with third-party products and
systems, and we may not be able to integrate these products with new or
existing products; and

- our products, or the back-end systems or other software used by our
clients, may not have adequately addressed the year 2000 problem, causing
our products to fail.

NETWORK OR INTERNET SECURITY PROBLEMS COULD DAMAGE OUR REPUTATION AND BUSINESS

Despite our security measures, the core of our network infrastructure could
be vulnerable to unforeseen computer problems. Although we believe we have taken
steps to mitigate much of the risk, we may in the future experience
interruptions in service as a result of the accidental or intentional actions of
Internet users, current and former employees or others. Unknown security risks
may result in liability to us and also may deter financial organizations from
licensing our software and services. Although we intend to continue to implement
and establish security measures, there can be no assurance that measures we have
implemented will not be circumvented in the future, which could have a material
adverse effect on our business, financial condition or results of operations.

The occurrence of any of these problems could reduce product demand from
potential customers and cause existing customers to terminate their license or
data center contracts with us. These problems could also require us to spend
significant capital to remedy any failure and could subject us to costly
litigation with clients or their end users.

WE MAY BECOME INVOLVED IN LITIGATION OVER PROPRIETARY RIGHTS, WHICH MAY BE
COSTLY AND TIME CONSUMING

Other parties may assert that our products, trademarks or other proprietary
rights require a license of intellectual property rights or infringe, or may
infringe, on their intellectual property rights. Any claims, with or without
merit, could:

- be time consuming;

- result in costly litigation;

- cause product shipment delays; or

- require us to enter into royalty or licensing agreements.

Royalty or licensing agreements, if required, may not be available on terms
acceptable to us, or at all, which could harm our business, financial condition
and results of operations. Litigation to determine the validity of any claims
could result in significant expense to us and divert the efforts of our
technical and management personnel from productive tasks, whether or not the
litigation is determined in our favor. In the event of an adverse ruling, we may
be required to:

- pay substantial damages;

- discontinue the use and sale of infringing products;

- expend significant resources to develop non-infringing technology; or

- obtain licenses to infringing technology.

Our failure to develop or license a substitute technology could significantly
harm our business.

We expect software to be increasingly subject to third-party infringement
claims as the number of competitors grows and the functionality of products in
different industry segments overlaps. Third parties may have, or may eventually
be issued, patents that would be infringed by our products or technology. Any of
these third parties could make a claim of infringement against us with respect
to our products or technology. In addition, we may become involved in costly and
time consuming litigation to protect the validity of our proprietary rights,
including patents and trademarks.

5

IF WE FAIL TO DEVELOP AND EXPAND OUR DISTRIBUTION CHANNELS, IT WOULD IMPEDE
REVENUE GROWTH

An integral part of our strategy is to develop multiple distribution
channels, including a field sales force, value added resellers and original
equipment manufacturers. We intend to continue to expend resources to develop
the reseller channel. The loss of resellers, their failure to perform under
agreements with us, or our inability to attract and retain new resellers with
the technical, industry and application expertise required to market our
products successfully in the future could harm our business. To the extent that
we are successful in increasing our sales through resellers, those sales will be
at discounted rates, and our revenue for each sale will be less than if we had
licensed the same products to the customer directly.

Expansion of our direct distribution channel depends upon the increased
productivity of existing field sales forces and our ability to integrate and
train new sales personnel. The cost of these efforts could exceed the revenue
generated, and our sales and marketing organization may not be able to compete
successfully against the significantly more extensive and well-funded sales and
marketing operations of many of our current or potential competitors.

OUR MARKET IS HIGHLY COMPETITIVE AND, IF WE ARE UNABLE TO KEEP PACE WITH
EVOLVING TECHNOLOGY, OUR REVENUE AND FUTURE PROSPECTS MAY DECLINE

The market for our products and services is characterized by rapidly
changing technology, intense competition and evolving industry standards. We
have many competitors who offer various components of our suite of applications
or who use a different technology platform to accomplish similar tasks. In some
cases our existing clients also use some of our competitors' products. Our
future success will depend on our ability to develop, sell and support
enhancements of current products and new software products in response to
changing client needs. If the completion of the next version of any of our
products is delayed, our revenue and future prospects could be harmed. In
addition, competitors may develop products or technologies that the industry
considers more attractive than those we offer or that render our technology
obsolete.

A SIGNIFICANT PORTION OF OUR CLIENTS ARE IN THE RAPIDLY CONSOLIDATING FINANCIAL
SERVICES INDUSTRY, WHICH IS SUBJECT TO ECONOMIC CHANGES THAT COULD REDUCE DEMAND
FOR OUR PRODUCTS AND SERVICES

For the foreseeable future, we expect to derive most of our revenue from
products and services we provide to the banking industry and other financial
services firms such as insurance companies. Changes in economic conditions and
unforeseen events, like recession or inflation, could occur and reduce
consumers' use of bank services. Any event of this kind, or implementation for
any reason by banks of cost reduction measures, could result in significant
decreases in demand for our products and services.

Mergers and acquisitions are pervasive in today's banking industry. Our
existing clients may be acquired by or merged into other financial institutions
which already have their own financial Internet software solution or which
decide to terminate their relationships with us for other reasons. As a result,
our sales could decline if an existing client is merged into or acquired by
another company.

INFRINGEMENT OF OUR PROPRIETARY TECHNOLOGY COULD HURT OUR COMPETITIVE POSITION
AND INCOME POTENTIAL

Our success depends upon our proprietary technology and information. We
rely on a combination of patent, copyright, trademark and trade secret laws and
confidentiality procedures to protect our proprietary technology and
information. Because it is difficult to police unauthorized use of software, the
steps we have taken to protect our services and products may not prevent
misappropriation of our technology. Any misappropriation of our proprietary
technology or information could reduce any competitive advantages we may have or
result in costly litigation.

We now also have a significant international presence. The laws of some
foreign countries, including the laws of Belgium, where our subsidiary, FICS, is
headquartered, may not protect our proprietary technology as well as the laws of
the United States. Our ability to protect our proprietary technology abroad may
not be adequate.

4

IF WE ARE UNABLE TO ATTRACT AND RETAIN HIGHLY SKILLED TECHNICAL EMPLOYEES, WE
MAY NOT BE ABLE TO COMPETE

Based on the significant growth in our operations, we believe that our
future success will depend in large part on our ability to attract and retain
highly skilled technical personnel. Because the development of our software
requires knowledge of computer hardware, as well as a variety of software
applications, we need to attract and retain technical personnel who are
proficient in all these disciplines. There is substantial competition for
employees with the technical skills we require. If we cannot hire and retain
talented technical personnel, this could adversely affect our growth prospects
and future success.

IF WE ARE UNABLE TO EFFECTIVELY MANAGE OUR EXPECTED GROWTH, WE WILL NOT BE ABLE
TO SUCCESSFULLY IMPLEMENT OUR BUSINESS PLAN

We expect to grow rapidly. Our failure to manage our growth effectively
could impair our ability to successfully implement our business plan. Our growth
will place additional demands on our management, operational capacity and
financial resources, including our ability to recruit non-technical personnel
for management, sales, marketing and delivery positions. Because many of our
implementation and service engagements are large in scale, we must maintain
numerous teams of qualified technical personnel to serve our clients
efficiently. In addition, our systems, procedures, controls and resources,
particularly our client service resources, may not be adequate to support
continued expansion of operations.

INTERNET-RELATED LAWS COULD ADVERSELY AFFECT OUR BUSINESS

The adoption or modification of laws or regulations relating to the
Internet, or interpretations of existing law, could adversely affect our
business. Laws and regulations which apply to communications and commerce over
the Internet are becoming more prevalent. For example, a recent session of the
United States Congress resulted in Internet laws regarding copyrights, taxation
and the transmission of specified types of material. The European Union recently
enacted its own privacy regulations and is currently considering other Internet-
related legislation. The law of the Internet, however, remains largely
unsettled, even in areas where there has been some legislative action. It may
take years to determine whether and how existing laws such as those governing
intellectual property, privacy, libel and taxation apply to the Internet. In
addition, the growth and development of the market for online financial
services, including online banking, may prompt calls for more stringent consumer
protection laws, both in the United States and abroad, that may impose
additional burdens on companies conducting business online.

OUR VERTICALONE SERVICE MAY NOT SUCCEED IF FINANCIAL OR OTHER ACCOUNT PROVIDERS
DO NOT ALLOW US TO ACCESS END USERS' ACCOUNT INFORMATION FROM THEIR HOST SYSTEMS

Unless a significant number of financial organizations or other account
providers allow us to access their host systems to gather information for
aggregation by our VerticalOne service, we may not succeed in making the service
sufficiently useful for our clients' customers to consider it useful. Some
financial organizations or other account providers may object to this account
access and attempt to block or impede us from performing our aggregation
service. We may also choose to cease aggregating financial or other account
information from an objecting organization to preserve an existing or potential
client relationship or other business purpose.

RESTRICTIONS ON OUR EXPORT OF ENCRYPTED TECHNOLOGY COULD CAUSE US TO INCUR
DELAYS IN INTERNATIONAL SALES

Our solutions use encrypted technology, the export of which is regulated by
the United States government. If the United States government were to adopt new
legislation restricting the export of software or encryption technology, we
could experience delays or reductions in our shipments of products
internationally. In addition, existing or future export regulations could limit
our ability to distribute our solutions outside of the United States.

5
7

WE MAY NOT BE ABLE TO OBTAIN CAPITAL NEEDED FOR FUTURE GROWTH FROM EXTERNAL
SOURCES AND, IF WE OBTAIN THIS CAPITAL THROUGH EQUITY ISSUANCES, YOUR INTEREST
IN US COULD BE DILUTED OR, IF WE OBTAIN IT THROUGH DEBT, OUR OPERATING
FLEXIBILITY COULD BE LIMITED BY COVENANTS

We may require additional financing to support our continued operations and
for general corporate purposes. We may not be able to fund all of our future
capital needs from income from operations. Consequently, we may have to rely on
third-party sources of capital, which may not be available to us on favorable
terms, if at all. Our access to third-party sources of capital depends on a
number of factors, including the market's perception of our growth potential and
our present and future revenue. We may also pursue equity investments from
strategic partners in the future. If we pursue additional equity offerings, our
existing stockholders' interests will be diluted. If we decide to use debt
financing, we may have to comply with a variety of operating covenants which
could limit our operating flexibility.

FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET COULD NEGATIVELY AFFECT
OUR STOCK PRICE AND OUR ABILITY TO RAISE FUNDS IN NEW STOCK OFFERINGS

If our stockholders sell substantial amounts of our common stock, including
shares issued when options and warrants are exercised or shares of our preferred
stock are converted into common stock, in the public market following this
offering, the market price of our common stock could fall. These sales also
might make it more difficult for us to sell equity or equity-related securities
in the future.

As of February 29, 2000, we had 50,973,048 shares of common stock
outstanding, assuming no exercise of outstanding options or warrants or
conversion of preferred stock. As of February 29, 2000, holders of approximately
7.4 million restricted shares of our stock or vested options or warrants to
purchase restricted shares of our common stock, representing 14.5% of our shares
outstanding on that date, have rights which may require us to register their
shares with the SEC. In addition, in connection with our pending acquisitions,
we have agreed, if these acquisitions close, to register with the SEC up to
approximately 2.0 million additional restricted shares for sale for the accounts
of holders of stock and options of these companies. By exercising their
registration rights and causing a large number of shares to be sold in the
public market, these stockholders could cause the market price of our common
stock to fall. In addition, if these stockholders demand to include their shares
in one of our registration statements, our ability to raise needed capital could
be adversely affected.

As of February 29, 2000, there were outstanding employee stock options to
purchase 16,200,593 shares of our common stock, options and warrants to acquire
6,425,413 shares of our common stock, and 1,061,514 shares of preferred stock
convertible into an aggregate of 1,694,990 shares of our common stock. The
common stock issuable after vesting and upon exercise of these options and
warrants and upon conversion of this preferred stock will be eligible for sale
in the public market from time to time. The options and warrants generally have
exercise prices significantly below the current market price of our common
stock. We have also reserved an aggregate of 4,500,000 shares of our common
stock for issuance to the former stockholders of FICS if FICS meets specified
performance targets while operating as our subsidiary. The possible sale of a
significant number of these shares may cause the market price of our common
stock to fall.

OWNERSHIP OF OUR COMMON STOCK BY OUR OFFICERS, DIRECTORS AND PRINCIPAL
STOCKHOLDERS MAY PREVENT A CHANGE IN CONTROL

Our directors, executive officers, principal stockholders and their
affiliates beneficially own a significant percentage of our outstanding common
stock. This concentration of ownership may:

- delay, defer or prevent a change in control of our operations, which
could prevent you from selling your shares at a premium;

- impede a merger, consolidation, takeover or other business combination;
or

- discourage a potential acquirer from making a tender offer or otherwise
attempting to obtain control, and may cause the market price of our
common stock to fall.

8

MARKET VOLATILITY MAY CAUSE THE PRICE OF OUR COMMON STOCK TO DECLINE

The trading prices of Internet stocks in general, and ours in particular,
have experienced extreme price fluctuations in recent months. These fluctuations
often have been unrelated or disproportionate to the operating performance of
these companies. The valuations of many Internet stocks, including ours, are
extraordinarily high based on conventional valuation standards such as price to
earnings and price to sales ratios. These trading prices and valuations may not
be sustained. Any negative change in the public's perception of the prospects of
Internet or e-commerce companies could depress our stock price regardless of our
results of operations. Other broad market and industry factors may decrease the
trading price of our common stock, regardless of our operating performance.
Market fluctuations, as well as general political and economic conditions such
as recession or interest rate or currency rate fluctuations, also may decrease
the trading price of our common stock. In addition, our stock price could be
subject to wide fluctuations in response to the following factors:

- actual or anticipated variations in our quarterly operating results;

- announcements of new products, product enhancements, technological
innovations or new services by us or our competitors;

- changes in financial estimates by securities analysts;

- conditions or trends in the Internet and online commerce industries;

- changes in the market valuations of other Internet or online service
companies;

- developments in Internet regulations;

- announcements by us or our competitors of significant acquisitions,
strategic partnerships, joint ventures or capital commitments;

- unscheduled system downtime;

- additions or departures of key personnel; and

- sales of our common stock or other securities in the open market.

In the past, securities class-action lawsuits have often been instituted
against companies following stock price declines. Litigation of this type, if
instituted, could result in substantial costs and a diversion of our
management's attention and resources.

INTERNATIONAL OPERATIONS AND CURRENCY EXCHANGE RATE FLUCTUATIONS MAY ADVERSELY
AFFECT US

We conduct our business worldwide and may be adversely affected by changes
in demand resulting from:

- fluctuations in currency exchange rates;

- governmental currency controls;

- changes in various regulatory requirements;

- political and economic changes and disruptions;

- difficulties in enforcing our contracts in foreign jurisdictions;

- export/import controls;

- tariff regulations;

- difficulties in staffing and managing foreign sales and support
operations;

- greater difficulties in trade accounts receivable collection; and

- possible adverse tax consequences.

In addition, we maintain our international executive offices and a
significant portion of our maintenance, consulting, and research and development
operations in Belgium. Therefore, our operations may also be affected by
economic conditions in Belgium. These risks associated with international
operations may harm our business.

BUSINESS

OVERVIEW

We are the leading global infrastructure provider of Internet-based
solutions for financial organizations. Through our "engage, enable, everywhere"
strategy, we provide the solutions that empower our client banks, brokerage
firms and insurance companies to engage and enable their customers to access
their financial information and conduct transactions everywhere the Internet is
available. We believe our solutions empower our clients to increase revenue,
strengthen customer relationships and gain competitive advantage by meeting the
evolving needs of their customers across various lines of business, market
segments and delivery channels.

We provide a comprehensive set of Internet-based financial services
solutions which touch every significant facet of the financial services
industry. From banking, brokerage and insurance to personal financial management
and tax preparation capabilities, our suites of consumer, retail, small business
and corporate applications provide a comprehensive set of solutions for global,
national, regional and local financial organizations. Our solutions, including
our VerticalOne personal information aggregation service and our Edify
interactive voice response technology, reach beyond traditional online financial
services to help financial organizations deliver value to their customers,
resulting in greater customer retention and increased revenue opportunities for
our clients. In addition, we have implemented wireless solutions in the United
States, Europe and Australia that allow our clients' customers to access account
information and conduct transactions through cellular telephones and hand-held
personal digital assistants.

We built our revenue model based on charging our clients for our technology
as they use it to deliver added value to their customers. To date, we have
derived a significant portion of our revenues from licensing our solutions and
providing professional services. We generate recurring revenues based on the
numbers of our clients' end users who use the solutions we provide, as well as
from the transactions we process through our Data Centers.

INDUSTRY

Use of the Internet is growing dramatically. In 1999, International Data
Corporation, a global market research firm, estimated that there were 66 million
Internet users in the United States and 132 million Internet users worldwide. By
the end of 2002, IDC estimated that the number of Internet users will increase
to 125 million in the United States and 320 million worldwide. A 1998 U.S.
Department of Commerce study estimated that Internet users are spending an
increasing amount of time on the Internet, with Internet traffic doubling every
100 days.

The growing acceptance of the Internet as a safe, secure and cost-effective
means of doing business represents an enormous opportunity for companies to
generate additional revenues through Internet commerce. IDC estimated that
revenue from business-to-consumer e-commerce will increase from approximately
$15 billion in 1997 to more than $178 billion in 2003, a compound annual growth
rate of 51%. Forrester Research, a consulting and analysis firm, estimates that
revenue from business-to-business e-commerce will increase from approximately
$43 billion in 1998 to more than $1.3 trillion in 2003, a compound annual growth
rate of 98%. We expect Internet banking to increase in popularity, as well. As
Internet banking increases in popularity with consumers and businesses, we
expect more financial organizations to offer Internet-based financial services
to their customers. IDC estimated that the number of banks offering online
banking services will increase from 1,150 in 1998 to 15,845 by 2003.

Similar changes are occurring around the world. Forrester Research
estimates that nearly 16 million Europeans became Internet-enabled in 1999,
doubling penetration to 49 million Internet users, or 13% of the

8
10

population of Europe. In addition, Datamonitor, a market research firm, predicts
that there will be over 21 million people in Europe banking over the Internet by
2004. The market for financial services in Europe is changing dramatically with
the advent of a single currency and less restrictive work and travel laws across
a large block of Western Europe. Our clients and potential clients are taking
advantage of these changes to pursue pan-European financial services strategies
which we believe will rely heavily on the Internet.

Worldwide use of wireless telecommunications has grown rapidly as cellular
and other emerging wireless communications services have become more widely
available and affordable for the mass business and consumer markets. Advances in
technology, changes in telecommunications regulations and the allocation and
licensing of additional radio spectrum have contributed to this growth
worldwide. Dataquest, a market research firm, estimates that there were
approximately 217 million digital wireless subscribers worldwide at the end of
1998 and that the number of subscribers will grow to 706 million by the end of
2002.

While use of the Internet has grown, changes have occurred to the
regulatory framework facing financial organizations like banks, brokerage firms
and insurance companies. In the fourth quarter of 1999, Congress repealed the
Banking Act of 1933 (Glass-Steagall), which separated commercial banking from
investment banking, and also repealed a 1956 law that separated bank and
insurance companies. Under the current guidelines, banks, insurance companies
and securities firms are allowed to enter one another's businesses through
direct offerings or through mergers or consolidations.

As a result of these market trends and industry changes, financial
organizations must compete for customers who are demanding the enhanced service
and increased personal convenience they can derive by using the Internet. This
competition is accelerating the demand for an integrated technology solution
that satisfies the service demands of customers, while providing the financial
organizations with a convenient personalized communication and marketing
channel. Because of the technological difficulties, long development times and
risks associated with building internal solutions, many financial organizations
are seeking third-party providers, like us, to design and implement their
Internet solutions.

THE S1 ADVANTAGE

We believe we are well positioned to provide solutions to the problems
posed by the changing financial services industry because we offer financial
organizations a one-stop-shop for their Internet financial services needs. We
believe that we derive our competitive advantage from our:

- ability to serve financial organizations across all of their targeted
markets and applications;

- broad range of innovative products, including Internet financial services
applications, our personal information aggregation service and our
customer contact technology, all of which are scalable to meet increasing
end user demand;

- global reach with clients on five continents and 1,626 employees
worldwide;

- management team's experience, vision and expertise in the financial
services industry; and

- ability to offer our clients the option to implement our solutions
directly or to outsource them to our Data Centers.

We offer our solutions to all sizes and types of financial organizations,
ranging from small banks to global financial institutions, brokerage firms and
insurance companies. In addition, through our pending acquisition of Q-Up
Systems, Inc., we intend to expand our coverage of the community bank market. To
these financial organizations, we offer solutions designed to span all of their
targeted markets. We provide products that empower our clients to engage over
the Internet not only individuals of varying degrees of wealth and financial
sophistication, but also small businesses and large corporations.

To community banks and other financial organizations that prefer to focus
solely on their Internet banking strategies, we offer a complete turnkey,
Microsoft Windows NT-based Internet banking product. We have implemented our
NT-based product for more financial organizations than any other company
offering an NT-based Internet banking product. To financial organizations
desiring to offer additional functionality to

9
11

consumers, we offer a product that integrates banking, investments and insurance
applications with personalized content, resulting in a complete financial
destination site. We also offer business-oriented Internet-based products that
deliver banking and cash management along with customizable content. In
addition, we complement these financial services products with our personal
information aggregation service and our customer contact technology.

We have established a global infrastructure and distribution network
through which we deliver our products and services through our acquisitions of
FICS and Edify in November 1999 and our strategic relationship with Andersen
Consulting. Because all of our Internet financial services solutions can be
customized for use with multiple languages and currencies, we believe we are
well-positioned to exploit this infrastructure advantage through continued
global expansion. Since November 1999, we have established several new client
relationships abroad. In addition, we have licensed our wireless solutions to
clients in Greece, Luxembourg and Australia over the last year.

Our management team's experience, vision and expertise in the financial
services industry also differentiate us from our competitors. Using technology
we developed while we were a subsidiary of Security First Network Bank, in 1995
we launched SFNB as the first FDIC-insured Internet bank in the world. Our
executive team is consistently recognized for its industry experience, talent
and visionary strength. Our co-founder and chief executive officer, James S.
Mahan, III, was recently named one of the top ten most influential personalities
in banking by FutureBanker magazine. In addition, Mr. Mahan and virtually all of
our senior executives gained experience in the financial services industry
before joining us. We believe this experience provides us with insight into the
needs of financial organizations.

We believe our Data Center operations provide us with another advantage
over our competitors. We believe that Internet-based solutions are more
difficult for our clients to support than other technologies they may employ. As
a result, to meet our clients' increasing outsourcing needs, we built a Data
Center near our Atlanta headquarters. Through our Data Centers, we provide
organizations with a cost-effective alternative to building, staffing and
maintaining their own data centers to host their Internet financial services
offerings. Our Data Center operations provide us with recurring revenues from
our clients based on the number of their customers who are using our products.
Because we anticipate that global demand for outsourcing of Internet-based
financial applications will increase, we intend to expand our Data Center
operations internationally. We are currently establishing data center sites in
London and Singapore to serve our clients in Europe and the Asia/Pacific region.

THE S1 STRATEGY

We provide Internet-based solutions to financial organizations worldwide
through our "engage, enable, everywhere" strategy. Our solutions allow our
clients to engage and enable their customers to access their financial
information and conduct transactions with them everywhere the Internet is
available. Through our solutions, we enable our clients to extend and strengthen
customer relationships, increase revenue and create a competitive advantage. We
describe the key elements of our "engage, enable, everywhere" strategy below.

Maintain technology leadership. We have invested heavily in the
development of our technology since our inception. In February 2000, we received
a patent for our invention of the three-tier architecture, which combines local
data storage with interfaces to the main financial system, creates a superior
capability to access financial information for customers of our clients by
providing greater availability of the information and an interactive register.
In addition, we continue to engineer our technology to provide increased
scalability. Performance testing on our most recent version of our Consumer
Suite indicated that the product could support up to 20 million end users in a
typical client configuration. We also continue to expand the ability of our
product to work with all Internet-enabled devices. We have implemented wireless
solutions in the United States, Europe and Australia that enable customers of
our clients to access their account information and conduct transactions over
the Internet through cellular telephones and hand-held personal digital
assistants. We intend to expand the availability and breadth of our wireless
solutions to meet the growing demand we perceive for wireless solutions. We plan
to continue to offer leading-edge technology that empowers our clients to offer
feature-rich and easy-to-use Internet financial services in a secure
environment.

10
12

Continue to introduce leading-edge products and services. We plan to
develop and acquire additional products and enhancements to existing products to
respond to changing client needs and market demands. Our solutions enable end
users of our clients to consolidate, store, personalize and process their
financial information. We incorporate into our solutions a broad range of
products, allowing our clients to engage their customers over the Internet. For
example, we incorporate BroadVision's "One-to-One" marketing product in our
solutions, which allows our clients to market additional products and services
to particular customers based on their characteristics and the activities they
perform while using our products. Also, as a result of our acquisition of
VerticalOne Corporation in November 1999, we now offer an innovative aggregation
service that makes our solutions more appealing to end users who wish to view
all of their financial information and other personal account information at our
clients' Web sites. We also offer interactive voice response solutions.

Partner with leading distribution and implementation players. We intend to
expand and leverage our relationships with key business partners. These
relationships broaden our distribution network and provide resources that
contribute to effectively maximizing opportunities. For example, in 1999 we
entered into a relationship with Andersen Consulting. Andersen Consulting
provides us with associates whom we train to assist us in the implementation of
our products and also supports our marketing of our products to large financial
organizations worldwide. In addition, we have formed distribution alliances with
third-party data processors, including Fiserv, Inc., M&I Data Services and NCR
Corporation, through which we support our small and mid-sized financial
organization clients.

Continue to expand our operations internationally. Our acquisition of FICS
and Edify and our strategic relationship with Andersen Consulting have provided
us with a global infrastructure and distribution network through which we can
deliver our solutions. We plan to continue to expand our operations in Europe
and the Asia/Pacific region through continued development of integrated banking,
investment and insurance solutions. We also intend to market our aggregation
service and our wireless solutions aggressively, both alone and bundled with our
core products. In addition, we expect to expand our existing Data Center
operations to meet anticipated growth in international demand for outsourcing
services. We are currently establishing a European-based Data Center in London
and a Data Center in Singapore for our Asia/Pacific regional operations. Like
our existing Data Center in Atlanta, we are designing each of these new
facilities to host our entire line of products and to ensure the security of
data and communications. We may enhance our global expansion efforts through
strategic relationships or joint ventures with key players in a particular
region if we determine that joining forces can help us achieve our goals more
efficiently. In addition, we will evaluate and may pursue alternative capital
structures, including strategic partnerships, joint ventures or equity
offerings, to enhance our global expansion efforts. For example, in December
1999 we announced a letter of intent with Zurich Financial Services under which
Zurich would invest in a separate business unit that would operate our
European-based Data Center. We are continuing to evaluate that structure, as
well as alternative structures for our European operations.

Pursue strategic acquisitions. We intend to pursue strategic acquisitions
that would provide additional technology, product or service offerings,
additional industry expertise, a broader client base or an expanded geographic
presence. In November 1999, using these criteria, we acquired three companies:
Edify, based in Santa Clara, California; FICS, based in Brussels, Belgium; and
VerticalOne, based in Atlanta Georgia. Since January 1, 2000, we have entered
into agreements to acquire two additional companies: Davidge Data Systems, Inc.,
a New York, New York-based provider of order routing services to brokerage
firms; and Q-Up Systems, Inc., an Austin, Texas-based provider of Internet
financial services solutions to community banks. If we had closed on each of
these two pending acquisitions on March 8, 2000, we would have issued an
aggregate of approximately 2.6 million shares of our common stock and assumed
and issued options that, if exercised, would have required us to issue up to
approximately 1.7 million additional shares of our common stock.

We intend to structure our organization to maximize our ability to apply
our management team's experience and expertise to address the changing financial
services industry. In fiscal year 2000, we are operating our VerticalOne
subsidiary and our interactive voice response divisions as separate business
units that pursue their own business plans. We plan to operate Davidge and Q-Up
as separate business units after we close on these acquisitions, as well. We
will also continue to evaluate and make strategic investments in,

11
13

and develop relationships with, start-up companies that we believe offer promise
of developing additional products or services complementary to our own.

PRODUCTS AND SERVICES

We build integrated Internet-based solutions that enable our clients to
deliver value to their customers, allowing our clients to increase revenue,
strengthen customer relationships, and gain competitive advantage. Our core
financial services products enable customers of financial organizations to
access their account information and conduct most of their financial
transactions over the Internet. Our financial services products can be combined
with financial planning tools and personalized content which enhance our
clients' abilities to keep their customers engaged. Our recently acquired
VerticalOne aggregation service increases the frequency, duration and quality of
these customers' visits to our clients' Web sites. We also maintain a global
professional services staff whose members are fully trained in the customization
and implementation of our solutions.

Our products and services address the needs of financial organizations to
offer solutions across multiple markets ranging from the typical consumer to
high net worth individuals and from small businesses to large corporations. Our
products integrate components covering the full scope of the financial services
industry, including banking, brokerage and insurance applications. We design our
products to ensure scalability as the number of customers using our clients'
Internet financial services applications increases. Performance testing on the
most recent version of our Consumer Suite indicated that the product could
support up to 20 million end users in a typical client configuration.

We separate our product lines into those serving the consumer and business
markets. We describe the features of our products within each of these
categories below.

Consumer-Oriented Products

We offer two Internet banking solutions targeted to meet both the needs of
financial organizations that desire a turnkey solution and the needs of
organizations that desire a more comprehensive solution.

To community banks and other financial organizations that prefer to focus
solely on their Internet banking strategies, we offer S1 Retail Banking, a
Windows NT-based banking solution that is complete and ready to operate when
delivered to the financial organization. S1 Retail Banking offers a targeted
group of services and functionality ideal for financial organizations focused on
banking, and can be customized with optional bill payment and presentment and
targeted marketing capabilities. S1 Retail Banking is the most widely installed
NT-based Internet solution at mid-sized and large banks.

Our other Internet banking product, S1 Consumer Banking, may be integrated
with the rest of the S1 Consumer Suite products, resulting in a comprehensive
product offering. S1 Consumer Banking provides an interactive check register
that is updated daily with cleared transactions and real-time for any future
dated transactions entered by the customer. In addition, financial information
can be supplemented with personalized categories for reporting and financial
management.

The S1 Consumer Suite is comprised of the additional following
applications:

- S1 Consumer Investments

- S1 Relationship Management

- S1 Consumer Insurance

- S1 Bill Presentment

- Content and Planning Tools

The S1 Consumer Suite appeals to financial organizations that want to
integrate multiple capabilities for the convenience of their customers. The S1
Consumer Suite is a comprehensive and customizable suite that allows financial
organizations to provide their customers with Internet banking, brokerage, bill
presentment and payment and insurance products and services. In addition,
through the S1 Consumer Suite, by identifying

12
14

the activities they perform while using our applications, financial
organizations can engage in personalized "one-to-one" marketing of additional
products and services geared to meet the needs of their existing customers. This
suite creates financial destination sites with broad, robust functionality
integrated across multiple financial products, including many optional add-ons
such as customer care, tax preparation and financial planning tools.

Business-Oriented Products

S1 Business Suite. The S1 Business Suite is designed for financial
organizations that want to deepen their relationships with small to mid-sized
businesses by offering remote access to their financial information along with
cash and financial management tools. The S1 Business Suite delivers a wide range
of financial services including banking, cash management, and customizable
content to create a financial destination site for the business user.

S1 Corporate Suite. We developed the S1 Corporate Suite for financial
organizations that want to focus on their large corporate customers by offering
a comprehensive, Internet-based cash management offering. The S1 Corporate Suite
offers broad-ranging banking functionality over the Internet for global
payments, balance and transaction reporting, check services, customer messaging,
custody and trade finance. It is designed for financial organizations looking to
provide integrated Internet banking applications to meet their customers
worldwide needs.

Complementary Offerings

In addition to the products and services described above, we deliver a
number of other products and services that extend our core products.

Aggregation Service. Through our wholly owned subsidiary, VerticalOne, we
offer a service that consolidates, organizes and presents the personal account
information of our clients' customers at our clients' Web sites. Our service
allows customers of our clients to go to our clients' Web sites to view summary
snapshots of their account balances from a variety of sources, including:

- airline and other reward programs;

- communications companies, including telephone and cellular services;

- brokerage and other investment sites;

- credit card companies;

- banks;

- Web-based e-mail; and

- other service providers that bill customers over the Internet.

Because our aggregation service offers our clients' customers the
convenience of a single master password and user identification code, it allows
these customers to eliminate the need to remember and key in disparate user
names and passwords at each source's site. In addition, with our "Quick Login"
feature, our clients' customers can use a hyperlink to jump directly to their
opening screens at a particular Web site if they want to after viewing their
account balances from our clients' sites.

We have marketed our aggregation service successfully to non-financial
organizations including BellSouth Corporation and Disney's Go Network, and we
intend to continue to target other organizations that maintain an active
Internet presence. Moreover, we believe that this service is particularly useful
for clients that employ our financial services solutions. By combining our
financial services solutions, which consolidate the customer's financial data
within an organization, with our aggregation service, financial organizations
can act as an aggregator of their customers' account information from other
financial organizations or account sources. As a result, financial organizations
can position their Web sites as financial destinations that provide customers
with access to all of their personal account information.

13
15

Customer Contact Technology. We offer interactive voice response solutions
that allow organizations to automate, integrate and personalize interactions
with customers through multiple channels, yielding stronger, more profitable
relationships. Using customer-determined profiles and interests, our clients can
notify their customers about new products or services. Calls that do require
human assistance can automatically be routed to the most appropriate person. All
of these goals can be accomplished through a combination of channels, including
telephone, Internet, e-mail, fax, and pager.

In addition, we offer a natural language speech recognition product and an
optional marketing campaign management component that enables businesses to
deliver products and services to targeted prospects consistently through
multiple channels.

Data Center Services. In August 1999, we opened a new Data Center in
Atlanta to accommodate our clients' increasing outsourcing needs. The Data
Center employs the latest, proven technology to support some of our largest
financial organization clients. We earn recurring revenues for each end user we
process for our clients through our Data Center.

Through our Data Center operations, we provide organizations with a
cost-effective alternative to building, staffing and maintaining their own data
centers to host their Internet financial services offerings. By outsourcing to
our Data Centers, organizations can gain immediate access to highly skilled
information systems specialists who know the online financial services business
and can deliver solutions to the organizations' customers faster.

We expect to continue to extend our Data Center operations to meet
anticipated growth in international demand. We recently entered into a sublease
for property on which we are establishing a European-based Data Center. In
addition, we are currently establishing a Data Center in Singapore for our
Asia/Pacific regional operations as demand for these outsourcing services
increases. Like our existing Data Center in Atlanta, we are designing each of
these new facilities to host our entire line of products and to ensure the
security of data and communications.

Professional Services. We surround our applications with flexible
implementation, maintenance and support options. We provide professional
services for the installation and integration of our products, including
installation at third-party data processing centers and direct licensee sites or
integration of the financial organization's data processing systems within our
Data Centers. In addition, we provide training, consulting and product
enhancement services.

We maintain a worldwide customer engagements team of more than 512
qualified professionals to assist with customization and implementation of our
applications and to support the efforts of our partners to integrate our
solutions with their own. In addition, we have partnered with Andersen
Consulting, one of the world's largest and most highly regarded systems
integrators, to offer a comprehensive and experienced team of consultants and
implementation specialists. A significant number of Andersen Consulting
associates have already been trained on implementing our applications and are
now working actively with our organization to service our customers.

CLIENTS AND MARKETS

We provide innovative Internet-based financial services solutions to global
financial services organizations. We also provide aggregation services to
leading Internet portal providers. In addition, we provide our customer
relationship management technology to companies in the consumer goods,
manufacturing, insurance and healthcare, technology and telecommunications
industries.

During 1999, we provided implementation and product enhancement services
for State Farm Mutual Automobile Insurance Company. We derived 40% of our total
revenues in 1999 from State Farm. On a pro forma basis, giving effect to our
acquisitions of FICS, Edify and VerticalOne as if the transactions occurred on
January 1, 1999, State Farm accounted for 21% of our total revenue for 1999.

ALLIANCES AND PARTNERSHIPS

We have established strategic alliances with organizations around the globe
to deliver competitive and comprehensive Internet-based financial service
solutions to our customers. Through these global alliances, we intend to
accelerate the pace of innovation, implementation and service delivery to
financial organizations worldwide. Following is a description of four strategic
alliances that we consider particularly important to our operations:

Andersen Consulting LLP

In February 1999, we formed a strategic alliance with Andersen Consulting
to jointly develop business strategies and implementation processes that
increase an organization's ability to leverage new technology, enhance speed to
market and compete more effectively in delivery of Internet-based services. This
alliance added significant resources that helped expand our capacity for product
development, distribution, delivery and implementation. In addition, Andersen
Consulting agreed to promote us as its preferred provider of Internet banking
solutions. As part of the alliance, a member of the Andersen Consulting
worldwide organization made an investment in our common stock, and we issued to
Andersen Consulting a warrant to purchase additional shares of our common stock.
We expect to benefit from the extensive relationships Andersen Consulting has
established with strategic financial services companies throughout the world. In
addition, Jackson L. Wilson, Jr., Managing General Partner -- AC Ventures, a
unit of Andersen Consulting that invests in new and innovative businesses,
joined our Board of Directors in August 1999. Mr. Wilson is also a member of
Andersen Consulting's Executive Committee.

Hewlett-Packard Company

In February 1999, we entered into an alliance with Hewlett-Packard to
provide integrated financial services. As part of the alliance, Hewlett-Packard
made an investment in our common stock. Since February 1999, Hewlett-Packard has
promoted us as its preferred provider of Internet applications for the financial
services industry. We anticipate that this alliance will continue to expand our
distribution capacity through Hewlett-Packard's global infrastructure.

Intuit Inc.

In May 1999, we entered into a strategic agreement with Intuit to deliver
online financial software and services to financial organizations. In connection
with that agreement, Intuit made an investment in our common stock and we
granted Intuit an option to purchase a significant number of additional shares
of our common stock. Since signing this agreement, we have worked on integrating
Intuit's TurboTax software within our applications. Further, we plan to equip
several of our customers with personal financial management and income tax
preparation and electronic filing capabilities in time for preparation of
individuals' tax returns for the year 2000.

BroadVision, Inc.

We have established a relationship with BroadVision to integrate the
BroadVision "One-to-One" marketing product with our solutions. As part of this
relationship, we obtained a license to use and resell BroadVision's "One-to-One"
marketing suite of products and BroadVision made an investment in our common
stock. By integrating the "One-to-One" product into the S1 Consumer Suite,
financial services firms using our products will be able to collect and organize
data resulting from customer transactions and use that data to specifically
target cross selling of products.

15
17

ADVISORY RELATIONSHIPS

We maintain a Customer Advisory Council to provide our executive management
team with strategic intelligence, insight, forward vision and guidance to ensure
our strategic vision is aligned with the evolving market for Internet-based
financial services solutions. The Advisory Council:

- reviews product strategy;

- assesses potential strategic partnership opportunities;

- provides intelligence on competitive offerings and other financial
institutions; and

- provides technical guidance on product functionality.

The Advisory Council includes representatives of Citibank, BankAmerica, The
Principal Financial Group, Synovus Financial Corp., Royal Bank of Canada, and
other financial organizations.

In addition, we have established a Product Advisory Committee that assists
us in defining and prioritizing detailed requirements for the products that
comprise the S1 Consumer Suite, the S1 Business Suite and the S1 Corporate
Suite.

SALES AND MARKETING

We sell our solutions to small, mid-sized and large financial
organizations. As of February 29, 2000, our sales force was comprised of 189
professionals structured in three major regional groups -- Americas, EMEA
(Europe, Middle East and Africa) and APAC (Asia/Pacific/Australia). Within each
group, we divide our sales force into two teams: named accounts and field sales.
Our named accounts sales team manages our relationships with existing customers
and markets our products to the 300 largest financial organizations in the world
based on asset size. Our named accounts sales force focuses on developing
long-term relationships with senior management of large financial organizations,
typically including these organizations' chief executive officers and the heads
of their retail banking and information technology divisions. The sales cycle
for these large financial organizations generally lasts from six to 18 months.
Contracts we enter into with these large financial organizations typically have
multi-year terms. Once we have established a relationship with these
organizations and their senior management teams, we continue to market
additional products and services to them.

Our field sales team focuses on building successful relationships with
smaller financial organizations. In addition, our field sales team assumes
responsibility for our relationships with our distribution partners including
M&I Data Services, Fiserv and NCR, thereby maximizing our market penetration
through the reseller channel. Our acquisition of Q-Up will provide us with
additional relationships and management focus to further expand our penetration
into community financial institutions. The sales cycle for these small to mid-
sized financial organizations typically lasts from two to six months, and the
contracts we enter into with them typically provide for direct delivery and
service requirements which we perform over a shorter period of time than our
contracts with large financial organizations. To maximize the understanding of
our solutions, our sales support team provides functional and technical sales
support.

In addition to our internal sales efforts and our joint efforts with
distribution partners like Andersen Consulting, M&I Data Services, Fiserv and
NCR, we market our products and services in other ways to build awareness of the
S1 brand. Our marketing efforts include:

- participating in and exhibiting at industry conferences and trade shows;

- maintaining memberships in key industry organizations, such as Bank
Administration Institute and Global Concepts, a payment systems
consulting firm;

- establishing close relationships with industry analysts to help guide our
product development and marketing efforts; and

- establishing "preferred vendor" relationships like those we have
solidified with Andersen Consulting, Hewlett-Packard and Intuit.
16
18

PRODUCT AND SOFTWARE DEVELOPMENT

As of February 29, 2000, our product management and development staff
consisted of 483 employees located in three countries. Our product management
group is responsible for strategic product planning, managing customer and
market demands, performing competitive analysis and managing the product
roll-out process for each product under development. The department consists of
individuals with extensive industry expertise related to the product they are
managing. The product managers work closely with the development group to ensure
that the functionality in the product exceeds industry standards.

Our development group creates new products following an iterative and
incremental development life cycle. The software life cycle consists of six
phases: initiation planning, analysis-design, construction, testing,
implementation and maintenance. Our software developers have extensive
experience in advanced software development techniques and work closely with our
product managers to ensure that they are considering the complex processes
involved in financial services systems.

This same group is also responsible for quality assurance of products
utilizing expertise in software quality assurance techniques. The group utilizes
an incremental form of testing for all products. Testing is accomplished in
three separate phases: unit testing, system testing and integration testing.
These three phases or levels of testing accompany the product development cycle
from initial coding through product pre-release for each developmental project.
The goal of each testing phase is to detect errors at the earliest stage of the
system/product development cycle.

TECHNOLOGY

Our product architecture provides an open, scalable platform to maximize
the value and power of the applications while enabling integration of future
technologies.

Our platform is equipped to deliver hybrid solutions that are designed to
meet various business needs of our clients. We deliver both fat and thin server
capabilities to suit individual customer requirements. Fat server technology
provides the capability to consolidate the end user's financial data from
disparate host systems and allows end users to categorize and report on this
information. Thin server capabilities provide a cost-effective solution for
financial organizations that are looking to provide base functionality to their
customers.

Our applications are designed for various operating systems and platforms.
We offer solutions that operate within a UNIX or NT environment, as well as
solutions that run on IBM, HP or Sun Microsystems platforms. Our applications
are designed with open standards that facilitate integration with both front and
back-end systems. Our extensible open object architecture facilitates the
integration of applications developed on the same or disparate platforms,
developed by us or our partners, internal development teams or other third-party
application developers. We have integrated our applications with more than 90
different back-end systems to date. The resulting integrated solutions not only
leverage the individual strengths of these separate applications, but also
create new service opportunities that yield a higher value to financial
organizations than each of the applications alone. Multiple delivery channel
support and application integration is accomplished through the use of a number
of standards based on approaches such as Extensible Markup Language (XML),
Component Object Model (COM), CORBA and Open Financial Exchange (OFX).

Our Data Center provides access to host computers for messaging, online
updates and inquiry into the systems operating our solutions. All communications
between the applications running in the Data Center and the organization's host
network are routed through a Virtual Private Network connection in order to
provide enhanced security. The Data Center is responsible for ensuring
availability of all types of communications including online, email, frame relay
circuit and host communications. In addition, the Data Center provides
production, change control, job scheduling, data storage management, storage of
backups and job performance analysis for systems operating our products. Our
recovery plan provides the organization with a defined recovery site, data
processing resources and vital records required for restoration of all the
organization's operations in the Data Center.

COMPETITION

The market for online banking and financial software is competitive,
rapidly evolving and subject to technological change. With the continued
development of the Internet as an accepted avenue for providing financial
services, we expect competition to intensify. Currently, we perceive that our
primary competition comes from the in-house development efforts of our target
clients, as some financial organizations believe in using their own resources to
build solutions. We believe that this strategy is inefficient for financial
organizations because:

- building an Internet-based financial services solution greatly lengthens
time to market;

- building, maintaining and upgrading the solution is very costly;

- attracting and retaining the necessary technical personnel is difficult
for these organizations; and

- technology development may be too far outside the financial
organizations' core competencies to be effective or successful.

Additional competitors currently include software companies that provide
turnkey online banking and brokerage solutions and Internet integration tools.
Among the companies offering Internet banking solutions are Digital Insight
Corporation, BROKAT Infosystems AG, Corillian Corporation, Fundtech, Magnet,
IBM, BroadVision, Sybase and Online Resources Corporation.

Our primary competitors with respect to our aggregation service include
Yodlee, EZLogin and Corillian's OneSource product. The offerings of these
competitors are at various stages of development and marketing. In the customer
contact area, we compete principally with stand-alone interactive voice response
vendors including InterVoice-Brite, Inc., Lucent Technologies Inc., Periphonics
Corporation, Syntellect Technology Corporation and TALX Corp.

We believe that our ability to compete successfully depends on a variety of
factors, including:

- our ability to empower our clients to engage their customers by offering
our comprehensive, scalable and easy-to-use products;

- our ability to expand our existing offerings, maintain technological
leadership and introduce new products;

- our success with our global expansion efforts;

- the quality and reliability of our Data Centers and professional
services;

- our ability to integrate successfully the products and service offerings
of companies we acquire through strategic acquisitions;

- the reputation of our solutions in the marketplace; and

- our pricing policies.

INTELLECTUAL PROPERTY

Our success is partially dependent upon our leading-edge proprietary
technology and information. We rely upon a combination of patent, copyright,
trademark and trade secret laws and confidentiality procedures to protect our
proprietary technology and information. We generally enter into nondisclosure
agreements with our employees, contractors, consultants, distributors and
corporate partners that limit access to and distribution of our software,
documentation and other proprietary information.

In many cases, we make efforts to protect our proprietary software and
business practices by obtaining patents for such technology. In February 2000,
we were issued a patent based on our invention of a three-tier architecture with
local data storage to provide customers of our clients with access to their
account information at financial organizations. We currently have seven patents
pending on our technology. We cannot guarantee, however, that applications for
such patents will be granted by U.S. or international authorities, nor

18
20

can we assure that we will be able to enforce such patents, if issued, against
third parties. Further, we cannot be sure that a known or unknown competitor has
patented technology similar or identical to ours, and that such patents may take
priority over ours.

It is our intention to vigorously protect our innovations. Despite our
efforts to protect our proprietary software, unauthorized parties may attempt to
copy or otherwise obtain and use products or technology that we consider
proprietary and third parties may attempt to develop similar technology
independently. In particular, we provide our existing and potential distribution
partners with access to our product architecture and other proprietary
information underlying our licensed software. Policing unauthorized use of our
software is very difficult due to the nature of software, and, while we are
unable to determine the extent to which piracy of our software products exists,
software piracy can be expected to be a persistent problem. In addition,
effective protection of intellectual property rights may be unavailable or
limited in certain countries. Accordingly, there can be no assurance that the
steps we have taken to protect our services and products are adequate to prevent
misappropriation of our technology or that our competitors will not
independently develop technologies that are substantially equivalent or superior
to our technology.

GOVERNMENT REGULATION

We are subject to examination, and are indirectly regulated by, the Office
of the Comptroller of the Currency, the Board of Governors of the Federal
Reserve System, or "FRB", the Federal Deposit Insurance Corporation, the Office
of Thrift Supervision and the various state financial regulatory agencies that
supervise and regulate the banks and thrift institutions for which we provide
data processing services. Matters subject to review and examination by federal
and state financial institution regulatory agencies include our internal
controls in connection with our performance of data processing services and the
agreements giving rise to those processing activities. In addition, the FRB has
determined that three bank holding companies, Area Bancshares Corporation,
Huntington Bancshares Corporation and Wachovia Corporation, control our
subsidiary, S1, Inc. As a result, S1, Inc. is subject to restrictions on its
activities and supervision, regulation and examination by the FRB as a company
controlled by bank holding companies.

The adoption or modification of laws or regulations relating to the
Internet, or interpretations of existing law, could adversely affect our
business. Laws and regulations which apply to communications and commerce over
the Internet are becoming more prevalent. For example, a recent session of the
United States Congress resulted in Internet laws regarding copyrights, taxation
and the transmission of specified types of material. Congress also adopted
legislation imposing obligations on financial institutions to develop privacy
policies, restrict the sharing of non-public customer data with nonaffiliated
parties at the customer's request, and establish procedures and practices to
protect and secure customer data. These privacy provisions, which may apply to
us because of the broad definition of "financial institution" contained in the
legislation, will be implemented by regulations that will take effect on or
after November 12, 2000. Even if the regulations do not apply directly to us,
they will apply to our financial institution clients. In addition, the European
Union recently enacted its own privacy regulations and is currently considering
other Internet-related legislation. The law of the Internet, however, remains
largely unsettled, even in areas where there has been some legislative action.
It may take years to determine whether and how existing laws such as those
governing intellectual property, privacy, libel and taxation apply to the
Internet. In addition, the growth and development of the market for online
financial services, including online banking, may prompt calls for more
stringent consumer protection laws, both in the United States and abroad, that
may impose additional burdens on companies conducting business online. We are
also subject to encryption and security export laws which, depending on future
developments, could adversely affect our business.

Any development that substantially impairs the growth of the Internet or
its acceptance as a medium for transaction processing could render our business
or operations more costly, less efficient or impossible.

EMPLOYEES

As of February 29, 2000, we had 1,626 employees. Our employees are not
represented by a collective bargaining unit, and we believe our relationships
with our employees are satisfactory. In addition to full-time

19
21

employees, we have used the services of various independent contractors for
professional services projects and product development.

ITEM 2. PROPERTIES.

Our executive offices are currently located at 3390 Peachtree Road, NE,
Atlanta, Georgia. We have, however, entered into a lease for new executive
office space at a location near our current facilities and intend to move into
the new space once construction is completed in 2001. Our Atlanta-based Data
Center is located at 705 Westech Drive, Norcross, GA. Our European headquarters
are located at Excelsiorlaan 87, B-1930 Zaventem, Brussels, Belgium. We also
maintain offices in the United States in Boston, Charlotte, Dallas, and Santa
Clara. We maintain international offices in Johannesburg, Lisbon, London,
Luxembourg, Madrid, Melbourne, Paris, Rotterdam, Singapore and Sydney.

We lease all of our office space as well as our Data Center sites. We owned
computer equipment with a book value of $19.6 million at December 31, 1999.

ITEM 3. LEGAL PROCEEDINGS.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

FORWARD LOOKING STATEMENTS

The annual report and the documents incorporated into this annual report by
reference contain forward-looking statements within the safe harbor provisions
of the Private Securities Litigation Reform Act. These statements include
statements with respect to S1's, FICS's, Edify's and VerticalOne's financial
condition, results of operations and business and on the expected impact of the
FICS Transaction, the Edify Transaction and the VerticalOne Transaction on S1's
financial performance. Words such as anticipates, expects, intends, plans,
believes, seeks, estimates and similar expressions identify forward-looking
statements.

These forward-looking statements are not guarantees of future performance
and are subject to risks and uncertainties that could cause actual results to
differ materially from the results contemplated by the forward-looking
statements. These risks and uncertainties include:

- the possibility that the anticipated benefits from our recent acquisition
transactions will not be fully realized;

- the possibility that costs or difficulties related to our integration of
FICS, Edify and VerticalOne will be greater than expected;

- our dependence on the timely development, introduction and customer
acceptance of new internet services;

- rapidly changing technology and shifting demand requirements and internet
usage patterns;

- other risks and uncertainties, including the impact of competitive
services, products and prices, the unsettled conditions in the internet
and other high-technology industries and the ability to attract and
retain key personnel; and

- other risk factors as may be detailed from time to time in our public
announcements and filings with the SEC.

OVERVIEW

We are the leading global infrastructure provider of Internet-based
solutions for financial organizations. Prior to September 30, 1998, we were the
technology subsidiary of Security First Network Bank, which was the first
Internet bank. On September 30, 1998, we completed a reorganization to separate
our banking and technology businesses, and then sold the banking business to a
subsidiary of Royal Bank of Canada. In November 1999, we completed the
acquisitions of Edify, FICS and VerticalOne. On November 10, 1999, we changed
our name from Security First Technologies Corporation to S1 Corporation.

Revenues

We derive our revenues primarily from three sources:

Software licenses. We receive license fees from direct licensees and
third-party data processors. Direct licensees install and operate our products
in their own data centers. We generally receive an initial license fee plus
ongoing fees which are based on either the number of end-users or a percentage
of the initial license fee. We generally recognize revenues from software
license sales upon shipment where no significant obligations remain, in
accordance with AICPA Statement of Position 97-2. When services are considered
essential to the functionality of the software, the software license and the
related services are recognized over the implementation period using the
percentage of completion method of accounting.

A portion of our software license revenue is being recognized on a
straight-line basis over either the term of the agreement or, for contracts
without a term, the estimated period during which post-contract support is
expected to be provided. Under these arrangements, post-contract support and
maintenance were bundled as

23
25

part of the license agreements and sufficient vendor specific evidence did not
exist to allocate the total fee to all elements of the arrangement.

Third-party data processors install our products in their own data
processing centers and license the product to their client institutions,
typically smaller financial services entities like community banks and thrifts.
We receive monthly fees from third party data processors based on the total
number of end-users served by the processors' client institutions. These fees
are recognized as revenue in the period earned.

Professional Services. We provide professional services related to the
installation and integration of our products. These services include:

- installing the product at direct licensees and third-party data
processing centers;

- integrating the financial organization data processing systems with our
data center for data center clients;

- providing product enhancements;

- consulting; and

- training.

Revenues derived from contracts to provide services on a time and materials
basis are recognized as the related services are performed. Revenues from
professional services provided on a fixed fee basis are recognized using the
percentage of completion method, measured by the percentage of labor hours
incurred to date to estimated total labor hours for each contract.

Data Center. We receive recurring monthly fees from financial institutions
that have chosen to use our software and outsource the processing of their
financial transactions to our data center. These fees are based on the number of
end users of the client institution. In addition, we receive monthly fees for
technical support. We recognize these revenues as the services are performed.

Expenses

We expect to continue making significant investments in product development
to enhance our existing products, develop new products and further advance our
technology. Future expenditures in product development will be primarily
attributable to the addition of software development personnel with the
technological and industry expertise relevant to our technology.

We expect to increase our sales and marketing efforts to expand our
customer base. We expect the sales and marketing staff, which numbered 189 at
December 31, 1999, to grow significantly during 2000. We also intend to continue
promoting our products and services through conferences, seminars, direct
marketing and trade publications.

We record software development costs in accordance with Financial
Accounting Standards Board Statement No. 86, "Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed". We currently do
not have any capitalized software development costs.

We had net operating loss and tax credit carryforwards of approximately
$211.0 million at December 31, 1999 with expiration dates beginning in the year
2010 and ending in the year 2019. Of this amount, $87.1 million related to stock
option tax deductions, which will be reflected as additional paid-in capital
when realized.

We have incurred annual and quarterly losses from operations since
inception. At December 31, 1999, we had an accumulated deficit of $207.9
million.

BUSINESS ACQUISITIONS

On November 10, 1999, we completed the acquisitions of Edify and
VerticalOne. On November 18, 1999, we completed the acquisition of FICS. All
three acquisitions have been accounted for as purchase

24
26

business combinations. Accordingly, the consolidated financial statements
include the results of operations of Edify and VerticalOne from November 1, 1999
and the results of operations of FICS from December 1, 1999.

We exchanged 5,966,333 shares of common stock and 1,319,044 employee stock
options with a value of approximately $378.2 million for all of the outstanding
shares and stock options of Edify. Of the total purchase price of $381.7
million, which includes $3.5 million of costs incurred directly related to the
acquisition, we allocated $296.7 million to goodwill, $34.0 million to
identifiable intangible assets, $20.0 million to in-process research and
development and $31.0 million to net assets acquired.

We exchanged 3,842,487 shares of common stock and 471,440 employee stock
options with a value of approximately $161.4 million for all of the outstanding
shares and stock options of VerticalOne. Of the total $179.4 million purchase
price, which includes $3.0 million of acquisition costs and $15.0 million of
preferred stock purchased before the closing of the acquisition, we allocated
$126.2 million to goodwill, $22.5 million to identifiable intangible assets,
$7.3 million to in-process research and development and $23.4 million to net
assets acquired.

We exchanged 10,000,000 shares of common stock and 1,149,638 employee stock
options with a value of approximately $421.3 million for all of the outstanding
shares and stock options of FICS. Of the total $426.1 million purchase price,
which includes $4.8 million of costs incurred directly related to the
acquisition, we allocated $401.3 million to goodwill, $48.0 million to
identifiable intangible assets, $32.0 million to in-process research and
development and $55.2 million to net liabilities acquired. The former FICS
stockholders may also be able to obtain up to an additional 4,500,000 shares of
our common stock over a two-year period if FICS meets specified criteria while
operating as our subsidiary.

RESULTS OF OPERATIONS

The following discussion of our results of operations for the years ended
December 31, 1997, 1998 and 1999 is based on data derived from the statements of
operations contained in our audited consolidated financial statements appearing

YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998

Revenues

Total revenues increased by $68.7 million to $92.9 million for the year
ended December 31, 1999 from $24.2 million in the year ended December 31, 1998,
an increase of 284%. The components of 1999 revenue were $19.1 million in
software license fees, $56.4 million in professional service fees, $8.9 million
in data center fees and $8.5 million in other revenue. As a result of the size
of the companies with which we do business, the magnitude of our implementations
and our limited amount of capacity to perform implementations, a significant
portion of our revenues may be attributed to a limited number of clients in any
given period.

Software Licenses. Software license fees increased by $14.3 million to
$19.1 million in the year ended December 31, 1999 from $4.8 million in the year
ended December 31, 1998, an increase of 298%. Software license fees represented
21% of total revenues in the year ended December 31, 1999 compared to 20% of
total revenues in the year ended December 31, 1998. Approximately $9.9 million
of the increase in software license fees relates to the acquisitions of Edify
and FICS in the fourth quarter of 1999. Approximately $4.0 million of the
remaining increase relates to the recognition of revenue from licensing
agreements entered into in the fourth quarter of 1998. These license fees have
been recorded as deferred revenue and are recognized as revenue over a
three-year maintenance period.

Professional Services. Professional services revenues increased by $42.7
million to $56.4 million in the year ended December 31, 1999 from $13.7 million
in the year ended December 31, 1998, an increase of 312%. Professional services
revenues represented 61% of total revenues in the year ended December 31, 1999
compared to 57% of total revenues in the year ended December 31, 1998.
Approximately $8.3 million of the increase relates to the acquisitions of Edify
and FICS during the fourth quarter of 1999. Excluding the effect of the
acquisitions, the increase in professional services revenue related to several
large implementation projects and product enhancement projects performed for
existing clients during 1999.

Data Center. Data Center revenues increased by $5.7 million to $8.9
million in the year ended December 31, 1999 from $3.2 million in the year ended
December 31, 1998, an increase of 178%. Data Center revenues represented 10% of
total revenues in the year ended December 31, 1999 compared to 13% of total
revenues in the year ended December 31, 1998. The decrease in Data Center
revenue as a percentage of total revenues is a result of the increase in total
revenues due to the acquisitions discussed above. The dollar increase can be
attributed to increased end user demand for our Internet financial applications,
minimum fees for new financial institutions implemented during the year and
increased support fees. The average quarterly revenue per end user increased
slightly to $15.45 in the fourth quarter of 1999 from $15.21 in the fourth
quarter of 1998. We anticipate that the average quarterly revenue per end user
will decrease as financial services entities increase the number of their
customers using our product.

26
28

Revenues associated with the our Data Centers are directly influenced by
the number of financial services entities that are using our products through
our Data Centers and the number of end users of these financial services
entities. During the month of December 1999, our Atlanta-based Data Center
processed in excess of 347,000 Internet accounts, representing approximately
226,000 end users. This amount represents an increase of 134% in the number of
accounts processed from approximately 148,000 and an increase of 143% in the
number of end users from approximately 93,000 for the month of December 1998.

Other. Other revenue increased by $6.1 million to $8.6 million in the year
ended December 31, 1999 from $2.5 million in the year ended December 31, 1998,
an increase of 244%. Other revenue, primarily related to the sale of third-party
hardware and software used in connection with our products, represented 9% of
total revenues in the year ended December 31, 1999 compared to 10% of total
revenues in the year ended December 31, 1998. The increase relates to the sale
of third party hardware and software for two large implementations, which
occurred during 1999. We do not expect to experience this level of other
revenues in future periods.

Direct Costs

Direct costs increased by $35.0 million to $53.1 million in the year ended
December 31, 1999 from $18.1 million in the year ended December 31, 1998, an
increase of 193%. Direct costs represented 57% of total revenues in the year
ended December 31, 1999 compared to 75% of total revenues in the year ended
December 31, 1998.

Software License Costs. Direct software license costs consist primarily of
the cost of third-party software used in our products. Direct costs associated
with software licenses increased by $139,000 to $642,000 in the year ended
December 31, 1999 from $503,000 in the year ended December 31, 1998, an increase
of 28%. Direct costs associated with software licenses represented 3% of
software license fees in the year ended December 31, 1999 compared to 10% of
software license fees in the year ended December 31, 1998. The decrease in
direct costs as a percentage of revenue from 1998 to 1999 relates primarily to
license sales generated from acquired companies that did not include third-party
software. We anticipate that direct costs associated with software licenses will
increase in future periods as we sell additional products that include
third-party software.

Professional Services Costs. Direct professional services costs consist
primarily of personnel and related infrastructure costs. Direct costs associated
with professional services increased by $28.2 million to $36.3 million in the
year ended December 31, 1999 from $8.1 million in the year ended December 31,
1998, an increase of 348%. The increase in direct professional services costs
relates primarily to increased personnel working on an increased number of
professional services projects. In addition, the increase relates to the
acquisitions of Edify and FICS during the fourth quarter of 1999. Direct costs
associated with professional services represented 64% of professional services
revenues in the year ended December 31, 1999 compared to 59% of professional
services revenues in the year ended December 31, 1998. We anticipate that
professional services margins will decrease in future periods as the acquired
companies historically experienced lower professional services margins than we
experienced on a stand-alone basis.

Data Center Costs. Direct Data Center costs consist of personnel and
computer equipment costs. Direct costs associated with Data Center services
increased by $1.8 million to $9.0 million in the year ended December 31, 1999
from $7.2 million in the year ended December 31, 1998, an increase of 25%. The
increase in direct Data Center costs is primarily attributable to additional
costs of our new Atlanta-based Data Center facility, which went into full
operation in July 1999. Direct Data Center costs represented 101% of Data Center
revenues in the year ended December 31, 1999 compared to 225% of Data Center
revenues in the year ended December 31, 1998. The improvement was primarily the
result of increased end user volume.

Other Direct Costs. Other direct costs consist of the cost of third-party
hardware and software sold to customers for use with our products. Other direct
costs increased by $4.8 million to $7.1 million in the year ended December 31,
1999 from $2.3 million in the year ended December 31, 1998, an increase of 209%.
The increase relates to the sale of third-party hardware and software for two
large implementations, which

27

occurred during 1999. Other direct costs represented 83% of other revenues in
the year ended December 31, 1999 compared to 92% of other revenues in the year
ended December 31, 1998.

Operating Expenses

Operating expenses increased by $131.9 million to $167.1 million in the
year ended December 31, 1999 from $35.2 million in the year ended December 31,
1998, an increase of 375%.

Selling and Marketing. Selling and marketing expenses increased by $7.5
million to $12.2 million in the year ended December 31, 1999 from $4.7 million
in the year ended December 31, 1998, an increase of 160%. Selling and marketing
expenses were 13% of total revenues in the year ended December 31, 1999 compared
to 20% of total revenues in the year ended December 31, 1998. The dollar
increase was due primarily to the acquisition of Edify during the fourth quarter
of 1999. Edify's sales model was targeted at a larger number of smaller
financial institutions, resulting in higher sales expense as a result of having
a larger sales force. The decrease in selling and marketing expenses as a
percentage of sales was due to our ability to leverage our relatively fixed
selling and marketing expenses over a larger revenue base.

Product Development. Product development expenses increased by $10.2
million to $24.0 million in the year ended December 31, 1999 from $13.8 million
in the year ended December 31, 1998, an increase of 74%. Product development
expenses were 26% of total revenues in the year ended December 31, 1999 compared
to 57% of total revenues in the year ended December 31, 1998. The dollar
increase relates primarily to an increase in personnel expenses for additional
product development initiatives, the integration of the products of acquired
companies and the acquisitions of Edify and FICS. During 1999, we completed the
development of the next version of Consumer Suite and continued development
efforts on bill presentment, the next version of investments and the integration
of the Intuit products with our products. The increase in product development
costs represents our commitment to enhancing the current products by migrating
the existing products to a more efficient software architecture and to
developing new applications. The decrease as a percentage of total revenues in
the year ended December 31, 1999 from the year ended December 31, 1998 resulted
from our ability to leverage product development expenses over a larger revenue
base.

General and Administrative. General and administrative expenses increased
by $8.4 million to $13.9 million in the year ended December 31, 1999 from $5.5
million in the year ended December 31, 1998, an increase of 153%. General and
administrative expenses were 15% of total revenues in the year ended December
31, 1999 compared to 23% of total revenues in the year ended December 31, 1998.
The dollar increase is attributable to the increased personnel and
infrastructure related to the acquisitions of Edify, FICS and VerticalOne. The
decrease as a percentage of our total revenues in the year ended December 31,
1999 from the year ended December 31, 1998 resulted from our ability to leverage
general and administrative expenses over a larger revenue base.

Depreciation and Amortization. Depreciation and amortization expenses
increased by $1.6 million to $6.9 million in the year ended December 31, 1999
from $5.3 million in the year ended December 31, 1998, an increase of 30%.
Depreciation and amortization expenses were 8% of total revenues for the year
ended December 31, 1999 compared to 22% of total revenues in the year ended
December 31, 1998. Approximately $1.1 million of the increase was due to the
acquisitions during the fourth quarter of 1999. The remaining increase is
primarily related to the completion of our new Data Center in 1999.

Stock Option Compensation Expense. Stock option compensation expense
decreased by $400,000 to $1.1 million in the year ended December 31, 1999
compared to $1.5 million in the year ended December 31, 1998. Stock option
compensation expense represents the difference between the exercise price of
stock options granted and the fair value of our common stock at the time of
grant. This amount is being amortized over the vesting periods of the applicable
options. We expect this number to increase in future periods as a result of
options granted to employees of the newly acquired companies.

Marketing Cost for Warrant Issued. We recorded $715,000 of marketing costs
in the year ended December 31, 1999 related to the issuance to a third-party of
a stock warrant to purchase 84,994 shares of our common stock at an exercise
price of $80.00 per share. The warrant was issued in connection with a pilot

28
30

project and distribution agreement between the third-party and one of our
subsidiaries. The fair value of the warrant was determined based on the Black
Scholes option-pricing model. This amount is being amortized over the period of
the pilot project and distribution agreement, which is approximately 60 days. We
expect to recognize approximately $4.7 million of expense related to this
agreement in the first quarter of 2000.

Merger Related Costs. We recorded $8.7 million in the year ended December
31, 1999 related to the acquisitions of Edify, FICS, and VerticalOne. Merger
related costs consist primarily of expenditures related to building and
consolidating infrastructure and other operations of the companies we acquired
in the fourth quarter of 1999.

Acquired In-process Research and Development. In connection with the
acquisitions of Edify, FICS and VerticalOne, we allocated a portion of the
respective purchase prices to acquired in-process research and development. As
part of the process of analyzing each of these acquisitions, we made a decision
to buy technology that had not yet been commercialized rather than develop the
technology internally. We based this decision on factors such as the amount of
time it would take to bring the technology to market, available resources and
its progression in developing comparable technology, if any.

We determined the fair value of in-process research and development for
each of the above acquisitions using an income approach. This involved
estimating the present value of the after-tax cash flows expected to be
generated by the purchased in-process research and development, using
risk-adjusted discount rates and revenue forecasts as appropriate. Estimates of
future cash flows related to the in-process research and development were made
for each project based on our estimates of revenue, operating expenses and
income taxes from the project. These estimates were consistent with historical
pricing, margins and expense levels for similar products. Revenues were
estimated based on relevant market size and growth factors, expected industry
trends, individual product sales cycles and the estimated life of each product's
underlying technology. Estimated operating expenses, income taxes and charges
for the use of contributory assets were deducted from estimated revenues to
determine estimated after-tax cash flows for each project. Estimated operating
expenses include cost of goods sold, selling, general and administrative
expenses and research and development expenses. The research and development
expenses include estimated costs to maintain the products once they have been
introduced into the market.

The selection of the discount rate was based on consideration of our
weighted average cost of capital, as well as factors including the useful life
of each technology, profitability levels of each technology, the uncertainty of
technology advances that were known at the time, and the stage of completion of
each technology. We believe that the estimated in-process research and
development amounts represent fair value and do not exceed the amount a third
party would pay for the projects.

At the date of acquisition, the in-process research and development
projects had not yet reached technological feasibility and had no alternative
future uses. Accordingly, the values allocated to these projects were
immediately expensed upon acquisition. Where appropriate, we deducted an amount
reflecting the contribution of developed technology to the anticipated cash
flows of in-process research and development projects. If the projects are not
successful or completed in a timely manner, our product pricing and growth rates
may not be achieved and we may not realize the financial benefits expected from
the projects. The acquisitions and related in-process research and development
expenses are detailed in the table below (in millions):



PURCHASE IN-PROCESS COSTS TO
COMPANY ACQUISITION DATE PRICE R&D EXPENSE COMPLETE
------- ----------------- -------- ----------- --------

Edify............................... November 10, 1999 $381.7 $20.0 $8.8
FICS................................ November 18, 1999 426.1 32.0 6.7
VerticalOne......................... November 10, 1999 179.4 7.3 4.9


Specific details relating to the three acquisitions are discussed below.

On November 10, 1999, we completed the purchase of Edify for $381.7
million. Edify was involved in the development of interactive voice response
("IVR") and related customer service technology. Edify also was

29
31

involved in the development of technology to provide financial institutions with
the means to deploy a suite of automated banking services via the Internet. The
allocation of $20.0 million to in-process research and development represents
its estimated fair value using the methodology described above. We allocated the
$20.0 million to the following projects: Electronic Workforce ("EWF") ($6.7
million) and Electronic Banking System ("EBS"), which was renamed S1 Retail
Banking after the acquisition ($13.3 million). At the time of the acquisition we
forecasted that aggregate revenues attributable to the projects would reach
approximately $120.0 million in 2000. We expected revenues for the projects to
peak between 2001 to 2003 and decline thereafter through the end of the
products' lives (2006) as we expected to introduce new product technologies. At
the acquisition date, we estimated costs to complete the research and
development efforts related to the initial release of the projects to be
approximately $8.8 million. We utilized an average risk-adjusted discount rate
of 19% to discount projected cashflows.

Development of the in-process EWF technologies started in April 1999 and
had a scheduled release date of April 2000. The most substantial features of the
in-process EWF technologies were international capabilities and significant
improvements to scalability. These improvements are critical to compete in the
international markets. At the acquisition date, Edify had completed the
investigation phase, identified the business requirements, and created an
engineering task list with a preliminary development schedule, cost and a
resource plan. Efforts remaining included completion of the external and
internal design, quality assurance, and documentation. The EWF projects were
determined to be approximately 60% complete at the acquisition date.

Development of the in-process EBS technologies began in December 1998 and
was slated for completion in late 1999. This project consisted of one-to-one
marketing functionality and was designed to provide private branding and
cross-selling functionality. The technologies also were expected to incorporate
significant enhancements to bill payment and bill presentment functionality. At
the acquisition date, Edify had completed its technical investigation of the
project and determined the business requirements. Primary efforts remaining to
complete the project included external and internal implementation of the
branding functionality. The development of the in-process EBS technology was
completed in December 1999. Edify also was in the process of developing EBS
add-ons related to a small business portal. This project was expected to serve
as a one-stop solution for the small business owner. Features were slated to
include business banking as well as Web-based payroll, human resources, and
procurement applications. These development efforts were expected to require
significant work related to the integration of the architecture. At the
acquisition date, Edify had completed its investigation of the project,
developed a business case, and was in the process of finalizing the business
requirements. Development of a significant portion of the content of the
financial portal had also been completed. Efforts remaining included external
and internal design, IVR integration, and implementation of the financial
portal. This project was slated for introduction in the second quarter of 2000.
The EBS projects were determined to be approximately 40% complete at the
acquisition date.

On November 18, 1999, we completed the purchase of FICS for $426.1 million.
FICS was involved in the development of online customer interaction solutions
for corporate and retail banking customers. The allocation to in-process
research and development of $32.0 million represents its estimated fair value
using the methodology described above. We allocated approximately $19.0 million
to Corporate Internet Banking ("CIB"), which was renamed S1 Corporate Suite
after the acquisition, a system that will enable secure, browser-based corporate
banking over the Internet. We allocated approximately $13.0 million to Retail
Internet Banking ("RIB"), which was renamed S1 Retail Banking after the
acquisition, a system that will enable secure, browser-based retail banking over
the Internet. At the time of the acquisition, we forecasted that aggregate
revenues attributable to the projects would reach approximately $68.0 million in
2000. We expected revenues to peak in 2004 and decline thereafter through the
end of the products' lives (2006) as we expected to introduce new product
technologies. At the acquisition date, we estimated costs to complete the
research and development efforts to be approximately $4.3 million. We utilized
an average risk-adjusted discount rate of 25% to discount projected cashflows.

The CIB and RIB products were designed with three distinct segments: the
core, localization and customization layers. The primary development efforts
were to make the core and localization layers standardized, so that they require
minimal client-specific customization work.
30
32

The in-process CIB technology was slated for introduction in late 1999.
Additions planned for the technology included retrofitting the development of
billing into the new code base, introduction of file import/ export capability,
structured messaging functionality, fax-out functionality, and support of the
Euro currency. The in-process CIB technology was completed in December 1999. A
follow-on release requiring a major architecture upgrade was scheduled for
February 2000. This release was intended to support usage in geographical
markets with slow Internet connections and will also contain separate localized
modules for different regions. Several new features and functions also were
planned to be introduced, including trade finance functionality, multiple
payments, and automated customer notification. Developmental efforts as of the
acquisition date included creation of the concept plan, function analysis, and
high-level architecture design. The CIB project was determined to be
approximately 50% complete as of the acquisition date.

The in-process RIB technology was intended to introduce new customer
interface and filtering features. The new features are one-to-one marketing,
customer alerting functionality, and smart forms. Related efforts include
developmental projects utilizing an Extensible Markup Language ("XML")-based
tool kit to define data and business rules for internet banking solutions. These
related projects commenced in October 1998 and were intended to ease the work
required for customization and localization of the CIB and RIB products. The
work required addresses identification, performance benchmarking, and validating
to determine which middleware application is best and to customize its
performance. The feasibility of these new technologies was slated to be
validated in late 1999. Overall, the RIB project was estimated to be
approximately 70% complete at the acquisition date. The in-process RIB
technology was completed in December 1999.

On November 10, 1999, we completed the purchase of VerticalOne for $179.4
million. VerticalOne was involved in the development of a system that allows
users to aggregate their online personal account information on a single, highly
secure site. The allocation to in-process research and development of $7.3
million represents its estimated fair value using the methodology described
above. At the time of the acquisition, we forecasted that revenues attributable
to the in-process projects would reach approximately $6.5 million in 2000. We
expected revenues to peak in 2002 and decline thereafter through the end of the
product's life (2004) as we expected to introduce new product technologies. At
the acquisition date, we expected costs to complete the research and development
efforts related to the in-process project to be approximately $2.3 million. We
utilized an average risk-adjusted discount rate of 45% to discount projected
cashflows.

VerticalOne completed a limited-functionality version of its system in
September 1999, which was categorized as developed technology. In-process
technology consists of a vastly expanded version that will support commercially
necessary features such as access to multiple accounts from a single provider
(e.g., two checking or cellular phone accounts) and wireless access to the
system via devices such as the Palm VII personal digital assistant. These
features were completed in December 1999. The technology under development also
was slated to incorporate an extensive redesign of the system and related
databases to improve performance and increase scalability. Development efforts
related to creation of core engines to handle registration, data mining, account
aggregation, display information and quick login functions, as well as product
support systems that handle its interface with external content providers.
Development of these in-process technologies began in August 1999 and were
expected to finish in late 1999. These additional features were not completed in
1999 and are expected to be completed during the second quarter of 2000.
Developments of additional technologies, including the wireless overlay, also
began in August 1999 and were expected to be completed in the fourth quarter of
2000. Overall, the developmental efforts were estimated to be approximately 25%
complete as of the acquisition date.

Amortization of Acquisition Intangible Assets. Amortization of acquisition
intangible assets increased by $35.8 million to $40.2 million in the year ended
December 31, 1999 from $4.4 million in the year ended December 31, 1998, an
increase of 814%. Amortization of acquisition intangibles was 43% of total
revenues in the year ended December 31, 1999 compared to 18% of total revenues
in the year ended December 31, 1998. The increase related to the amortization of
goodwill and other identifiable intangible assets resulting from the
acquisitions of Edify, FICS, and VerticalOne. We anticipate amortization of
acquisition intangible assets in future periods to be approximately $306.8
million annually over the next three years.

31
33

Loss from Continuing Operations. Loss from continuing operations increased
by $96.5 million to $125.1 million in the year ended December 31, 1999 from
$28.6 million in the year ended December 31, 1998. The increase in net loss was
primarily the result of the increase in amortization of acquisition intangible
assets, merger related costs and acquired in-process research and development
resulting from the acquisitions in November 1999.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

Revenues

Our total revenues increased by $13.4 million to $24.2 million for the year
ended December 31, 1998 from $10.8 million in the year ended December 31, 1997,
an increase of 124%. The components of 1998 revenue were $4.8 million in
software license fees, $13.7 million in professional service fees, $3.2 million
in data center fees and $2.5 million of other revenue. As a result of the size
of the companies we do business with, the magnitude of our implementations and
our limited amount of capacity to perform implementations, a significant portion
of our revenues may be attributed to a limited number of clients in any given
period.

Software Licenses. Software license fees increased by $639,000 to $4.8
million in the year ended December 31, 1998 from $4.1 million in the year ended
December 31, 1997, an increase of 15%. Software license fees represented 20% of
total revenues in the year ended December 31, 1998 compared to 38% of total
revenues in the year ended December 31, 1997. This increase in software license
fees relates primarily to the recognition of revenue from the license fees
included in the technology and licensing agreements with Royal Bank of Canada.
These license fees have been recorded as deferred revenue and are recognized as
revenue over a three-year maintenance period. In addition, the increase in 1998
is also attributed to a license sale of our Relationship Management product.

Professional Services. Professional services revenues increased by $7.4
million to $13.7 million in the year ended December 31, 1998 from $6.3 million
in the year ended December 31, 1997, an increase of 117%. Professional services
revenues represented 57% of total revenues in the year ended December 31, 1998
compared to 58% of total revenues in the year ended December 31, 1997. The
dollar increase in professional services revenue in 1998 was driven by projects
at a number of large financial services institutions. Additionally, during 1998,
we began performing professional services related to product enhancement
projects, which include the initial development of an insurance product,
incorporation of BroadVision's One-to-One marketing with our Consumer Suite and
the integration of a new bill payment provider. Also, in 1997, we were limited
in the amount we could bill for professional services because of fixed pricing
for implementation services contained in initial contracts.

Data Center. Data Center revenues increased by $2.8 million to $3.2
million in the year ended December 31, 1998 from $411,000 in the year ended
December 31, 1997, an increase of 681%. Data Center revenues represented 13% of
total revenues in the year ended December 31, 1998 compared to 4% of total
revenues in the year ended December 31, 1997. This increase can be attributed to
increased end user demand for our Internet financial applications, the
initiation of minimum fees based on capacity requirements and increased
maintenance fees. The average quarterly revenue per billable end user increased
to $15.21 in the fourth quarter of 1998 from $9.55 in the fourth quarter of
1997. We anticipate that the average quarterly revenue per billable end user
will decrease as financial services entities increase the number of their
customers using the product.

Revenues associated with the data center are directly influenced by the
number of financial organizations that are using our products through our data
center and the number of end users of these financial organizations. During the
month of December 1998, the data center processed in excess of 148,000 Internet
accounts, representing approximately 93,000 end users. This represents an
increase of 199% in the number of accounts processed from approximately 49,500
and an increase of 184% in the number of end users from approximately 32,700 for
the month of December 1997.

Other. Other revenues were $2.5 million in the year ended December 31,
1998, representing 10% of total revenues in the year ended December 31, 1998.
Other revenue is primarily related to the sale of third

32
34

party hardware and software that are used in connection with our products. We
began selling third party hardware and software during 1998 related to two large
customer implementations.

Direct Costs

Direct costs increased by $4.2 million to $18.1 million in the year ended
December 31, 1998 from $13.9 million in the year ended December 31, 1997, an
increase of 30%. Direct costs represented 75% of total revenues in the year
ended December 31, 1998 compared to 128% of total revenues in the year ended
December 31, 1997.

Software License Costs. Direct software license costs consist primarily of
the cost of third-party software used in our products. Direct costs associated
with software licenses decreased by $1.1 million to $503,000 in the year ended
December 31, 1998 from $1.6 million in the year ended December 31, 1997, a
decrease of 69%. Direct software license costs in 1998 consisted primarily of
the cost of third-party software used in Relationship Management, whereas direct
software license costs in 1997 consisted primarily of the amortization of
purchased technology. This purchased technology included technology acquired in
previous acquisitions and software development costs paid to a contractor in
1995 and 1996. These costs have been amortized using the straight line method
over a period of three years. During the fourth quarter of 1997, we wrote off
the remaining unamortized balance of goodwill and purchased technology
associated with 1996 acquisitions after determining that there were minimal
future cash flows expected to be derived from these intangible assets as
discussed further below. Direct costs associated with software licenses
represented 10% of software license fees in the year ended December 31, 1998
compared to 39% of software license fees in the year ended December 31, 1997.

Professional Services Costs. Direct professional services costs consist of
primarily personnel and related infrastructure costs. Direct costs associated
with professional services increased by $2.8 million to $8.1 million in the year
ended December 31, 1998 from $5.3 million in the year ended December 31, 1997,
an increase of 53%. In addition to increases in personnel, we experienced delays
in early implementations of our products, due to integration issues with
clients' legacy mainframe systems, which resulted in increased implementation
costs, and loss accruals for some fixed-fee contracts. In 1998, we were in the
process of converting all financial services entities to version 4.0 of our
product. Direct costs associated with professional services represented 59% of
professional services revenues in the year ended December 31, 1998 compared to
84% of professional services revenues in the year ended December 31, 1997.

Data Center Costs. Direct Data Center costs consist of personnel and
computer equipment costs. Direct costs associated with Data Center services
increased by $271,000 to $7.2 million in the year ended December 31, 1998 from
$6.9 million in the year ended December 31, 1997, an increase of 4%. The
increase in direct Data Center costs is primarily attributable to the
establishment of the basic infrastructure of personnel and equipment needed to
process accounts for the growing number of end users of our financial services
clients. In an effort to contain Data Center costs, we ended our Data Center
facilities management agreement with a third party. We experienced cost savings
of approximately $300,000 in the fourth quarter of 1998 from both the
elimination of the cost-plus arrangement and the ability to use more efficiently
the existing infrastructure. Direct Data Center costs represented 225% of data
center revenues in the year ended December 31, 1998 compared to 1,679% of Data
Center revenues in the year ended December 31, 1997.

Other Direct Costs. Other direct costs consist of the cost of third party
hardware and software sold to customers for use with our products, which we
began selling in 1998. Other direct costs were $2.3 million in the year ended
December 31, 1998 and related to hardware and software purchased for two large
customer implementations.

Operating Expenses

Operating expenses increased by $9.5 million to $35.2 million in the year
ended December 31, 1998 from $25.7 million in the year ended December 31, 1997,
an increase of 37%.

33
35

Selling and Marketing. Selling and marketing expenses increased by
$418,000 to $4.7 million in the year ended December 31, 1998 from $4.3 million
in the year ended December 31, 1997, an increase of 10%. Selling and marketing
expenses were 20% of total revenues in the year ended December 31, 1998 compared
to 40% of total revenues in the year ended December 31, 1997. The dollar
increase was due primarily to an increase in the provision for uncollected
receivables as a result of the increased revenues in 1998. The decrease in
selling and marketing expenses as a percentage of sales was due to our ability
to leverage our relatively fixed selling and marketing expenses over a larger
revenue base.

Product Development. Product development expenses increased by $3.3
million to $13.8 million in the year ended December 31, 1998 from $10.5 million
in the year ended December 31, 1997, an increase of 31%. Product development
expenses were 57% of total revenues in the year ended December 31, 1998 compared
to 97% of total revenues in the year ended December 31, 1997. The dollar
increase relates primarily to an increase in personnel expenses for additional
product development initiatives. During 1998, we completed the development of
version 4.0 of our product and added loan functionality to the banking module.
In addition, during 1998, we released our Investments product and our
Relationship Management product, which integrates BroadVision's "One-to-One"
marketing suite of software products our product. The increase in product
development costs represents our commitment to enhancing current products by
migrating the existing products to more efficient software architecture and to
developing new applications. The decrease as a percentage of our total revenues
in the year ended December 31, 1998 from the year ended December 31, 1997
resulted from our ability to leverage product development expenses over a larger
revenue base.

General and Administrative. General and administrative expenses increased
by $1.5 million to $5.5 million in the year ended December 31, 1998 from $4.0
million in the year ended December 31, 1997, an increase of 38%. General and
administrative expenses were 23% of total revenues in the year ended December
31, 1998 compared to 37% of total revenues in the year ended December 31, 1997.
A portion of the dollar increase is attributable to charges related to the
termination of the facilities management agreement for the data center discussed
in depreciation and amortization below. In addition, general and administrative
expenses for 1998 include a charge of approximately $600,000 for professional
fees related to an unsuccessful transaction. The remaining increase relates to
the expanded personnel infrastructure to manage our growth. The decrease as a
percentage of our total revenues in the year ended December 31, 1998 from the
year ended December 31, 1997 resulted from our ability to leverage general and
administrative expenses over a larger revenue base.

Depreciation and Amortization. Depreciation and amortization expenses
increased by $3.6 million to $5.3 million in the year ended December 31, 1998
from $1.7 million in the year ended December 31, 1997, an increase of 212%.
Depreciation and amortization expenses were 22% of total revenues for the year
ended December 31, 1998 compared to 16% of total revenues in the year ended
December 31, 1997. The increase was due primarily to a one-time charge of
approximately $1.2 million related to the termination of an outsourcing contract
for the Data Center. In addition, we wrote-off computer equipment totaling
approximately $500,000 as the result of a physical inventory performed in 1998.
The remaining increase in depreciation and amortization related to increased
technology purchases in 1998 as a result of our growth.

Stock Option Compensation Expense. Stock option compensation expense
amounted to $1.5 million in the year ended December 31, 1998 compared to
$656,000 for the year ended December 31, 1997. Stock option compensation expense
represents the difference between the exercise price of stock options granted
and the fair value of our common stock at the time of grant. This amount is
being amortized over the vesting periods of the applicable options.

Amortization of Acquisition Intangible Assets. Amortization of acquisition
intangible assets charges decreased $141,000 to $4.4 million in the year ended
December 31, 1998 from $4.5 million in the year ended December 31, 1997, a
decrease of 3%. Amortization of acquisition intangible assets charges were 18%
of total revenues in the year ended December 31, 1998 compared to 42% of total
revenues in the year ended December 31, 1997. Included in the 1997 amortization
of acquisition intangible assets charges are one-time charges of $1.4 million
for the write-off of goodwill and purchased technology from previous
acquisitions. Excluding this charge in 1997, amortization of acquisition
intangible assets increased $1.3 million to $4.4 million in the year ended
December 31, 1998 from $3.1 million in the year ended December 31, 1997, an

34
36

increase of 42%. The increase related to the amortization of goodwill and other
identifiable intangible assets resulting from an acquisition in November 1997.

Results of Discontinued Operations

On September 30, 1998, we completed the sale of our banking operations to a
U.S. based subsidiary of Royal Bank of Canada. The Royal Bank subsidiary agreed
to pay $3.0 million in excess of the net assets sold. Also, there is a $1.5
million holdback for indemnification which we will receive by March 31, 2000 if
there are no indemnifiable claims. The banking operations included substantially
all of the loans and investment securities as well as its deposit relationships
and were legally separated from the technology operations through the formation
of a holding company and the contribution of $10.0 million in capital in
connection with the sale of the banking operations. We recorded a gain of
$812,000 on the sale of our banking operations. The gain on sale includes a $1.3
million charge related to the estimated fair value of options to purchase our
capital stock issued to Royal Bank in March 1998 in connection with the sale by
Security First Network Bank of the banking operations.

The losses from the banking operations are reflected in the accompanying
consolidated statements of operations as discontinued operations. Net interest
income for the nine month period ended September 30, 1998 was $1.3 million and
the net loss, excluding the gain on disposal, was $3.1 million. The increase in
the loss from discontinued operations for the three months ended September 30,
1998 is the result of one time charges related to the sale of the banking
operations.

CONSOLIDATED QUARTERLY OPERATING RESULTS

The following table shows selected unaudited consolidated quarterly
statement of operations data and that data as a percentage of total revenues for
the years ended December 31, 1999 and 1998. In our opinion, this unaudited
information has been prepared on substantially the same basis as the
consolidated financial statements appearing elsewhere in this Annual Report on
Form 10-K and includes all adjustments (consisting of normal recurring
adjustments) necessary to present fairly the unaudited consolidated quarterly
data. The unaudited consolidated quarterly data should be read together with the
audited consolidated financial statements and notes thereto appearing elsewhere
in this Annual Report on Form 10-K. The results for any quarter are not
necessarily indicative of results for any future period.

Due to our limited operating history, we cannot forecast operating expenses
based on our historical operating results. As a result, we establish expense
levels based in part on future projections of revenues. Revenues currently
depend heavily on our ability to sell software licenses and implementation and
outsourcing services for Internet banking solutions. Future revenues will likely
include more Data Center revenues, which will depend on our customers' ability
to attract and retain end users. If actual revenues are less than projected
revenues, we may be unable to reduce expenses proportionately, which could
adversely affect our operating results, cash flows and liquidity.

LIQUIDITY AND CAPITAL RESOURCES

We have funded our operations from private sales of common and preferred
stock. As of December 31, 1999, we had cash and cash equivalents of $67.9
million compared to $14.5 million at December 31, 1998 and investment securities
available for sale, which consisted entirely of equity securities, of $62.8
million at December 31, 1999 compared to $3.9 million at December 31, 1998.

In 1999, cash used in continuing operations was $30.0 million compared to
$11.9 in 1998. The increase in cash used in operations between 1999 and 1998 is
primarily the result of an increase in accounts receivable resulting from the
increase in revenues in 1999 as compared to 1998.

Cash provided by investing activities was $14.3 million in 1999 compared to
$7.4 million in 1998. The increase in cash provided by investing activities was
the result of the net cash acquired through acquisitions of $31.4 million, which
was offset by purchases of property and equipment of $17.1 million. Capital
expenditures in 1999 relate to the establishment of our new Data Center
facilities and expansion of our facilities infrastructure to accommodate our
growth.

Cash provided by financing activities was $69.1 million in 1999 compared to
$13.5 million in 1998. The increase relates to equity sales to Intuit,
Hewlett-Packard and Andersen Consulting, which are described below. In addition,
proceeds from the exercise of stock options was $11.9 million in 1999 compared
to $3.6 million in 1998. These increases were offset by payments made on notes
payable of $6.8 million in 1999.

On February 19, 1999, we entered into strategic alliances with
Hewlett-Packard and Andersen Consulting. As part of these alliances,
Hewlett-Packard agreed to make a $10.0 million equity investment in our common
stock and Andersen Consulting agreed to make a $4.0 million equity investment in
our common

37
39

stock. The stock sales closed as of April 30, 1999. At closing, we issued an
aggregate of 254,804 shares of our common stock. On February 19, 1999, we
granted to Andersen Consulting warrants to purchase up to an additional 200,000
shares of our common stock at $54.94 per share. The warrants will vest, if at
all, in three installments of 40,000, 80,000 and 80,000 shares only if we enter
into agreements to sell our services or license our products to a list of
specified customers as a result of our relationship with Andersen Consulting.
The warrants expire in February 2001. Vested warrants expire two years from the
vesting date. At December 31, 1999, 200,000 warrants were outstanding and none
were exercisable.

On February 25, 1999, we granted Royal Bank a warrant to purchase 800,000
shares of our common stock at a price of $30.00 per share. The warrant will vest
in four equal installments if, as of four annual measurement dates, beginning
one year after the completion of the implementation of specified applications
within our Consumer Suite, Royal Bank has an additional one million end users
using our software. Each installment terminates if the targeted customer levels
are not achieved or if an installment vests, the warrant terminates ninety days
after the vesting date. At December 31, 1999, 800,000 warrants were outstanding
and none were exercisable.

As part of the sale of the banking operations to Royal Bank, we issued to
Royal Bank four separate options to purchase up to an aggregate of $10.0 million
in capital stock. In 1998, Royal Bank exercised the first option for 420,876
shares at an exercise price of $5.94 per share. In 1999, Royal Bank exercised
options to purchase 382,614 shares at $6.53 per share and 347,831 shares at
$7.19 per share. The fourth option for 316,232 with a per share exercise price
of $7.91 expires in June 2000 and remains exercisable and outstanding at
December 31, 1999.

On February 25, 1999, we entered into an agreement with Royal Bank under
which Royal Bank agreed to implement certain applications within our Consumer
Suite. Royal Bank has agreed to pay $50.0 million to us on the following
schedule: the first $5.0 million was due to be paid no later than February 2000,
with the remaining amount to be paid equally over a four year period after Royal
Bank has implemented our software. Royal Bank paid us $5.0 million to satisfy
the first installment. If Royal Bank terminates its minimum payment obligation,
it is required to pay a termination fee equal to 40% of the unpaid amount. In
connection with this agreement, we issued 215,000 shares of newly designated
Series C redeemable convertible preferred stock. We recorded a subscription
receivable of $12.0 million, the estimated fair value of the preferred stock at
issuance, and will reduce such subscription receivable, including imputed
interest, as the payments under the arrangement are received. The right to
convert Series C on a two-for-one (post-split) basis into our common stock will
vest, if at all, in five installments. On February 25, 2000, the first
installment of 21,500 shares vested and became convertible. The remaining four
installments each comprised of 48,375 shares, will vest and become convertible
if Royal Bank has paid minimum fees of $11,250,000 per year for the first four
years following the completion date of the implementation. If the minimum fees
paid by Royal Bank at any anniversary date of the completed implementation
exceed the minimum fee level for the next anniversary date, Royal Bank may elect
to vest in the next installment of shares. The right to convert Series C into
common stock expires ninety days after the vesting date. Any shares of Series C
that do not vest and become convertible into shares of common stock on or before
March 31, 2004 become mandatorily redeemable by us for an amount equal to $0.01
per share. At December 31, 1999, no shares of Series C were vested and
convertible.

On May 16, 1999, we entered into a Stock Purchase and Option Agreement with
Intuit pursuant to which Intuit purchased 970,813 shares of our common stock for
$50.0 million. We also granted Intuit options to purchase 3,629,187 and 950,000
shares of our common stock that vested upon the closing of the Edify and FICS
acquisitions, respectively. Intuit was granted 445,000 additional options to
purchase our common stock that may become exercisable based on the achievement
of certain earn-out targets for FICS. All of the Intuit options were granted
with an exercise price of $51.50 per share and expire on November 10, 2004. At
December 31, 1999, 5,024,187 of these options were outstanding and 4,579,187
were exercisable. On March 5, 2000, Intuit transferred its shares and the
options to Intuit Ventures Inc., a wholly owned subsidiary of Intuit.

On December 23, 1999, we granted a vested, immediately exercisable warrant
to purchase 84,994 shares of our common stock at $80.00 per share in connection
with a pilot project and distribution agreement

38
40

between a third party and one of our subsidiaries. At December 31, 1999, the
warrant was outstanding and exercisable. The warrant expires on December 23,
2004.

At December 31, 1999, we had approximately $4.4 million outstanding and
approximately $2.2 million available under various line of credit facilities.
The amounts outstanding under the lines of credit at December 31, 1999 were
subsequently paid. Approximately $2.0 million was outstanding at December 31,
1999 under notes payable to a bank and we expect to pay this amount in 2000.

We believe that our current cash and cash equivalents will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
at least the next 12 months. If cash generated from operations is insufficient
to satisfy our liquidity requirements, we may seek to sell additional equity or
debt securities or establish an additional credit facility. The sale of
additional equity or convertible debt securities could result in additional
dilution to our stockholders. The incurrence of additional indebtedness would
result in increased fixed obligations and could result in operating covenants
that would restrict our operations. We cannot assure you that financing will be
available in amounts or on terms acceptable to us, if at all.

Basic loss per share is calculated as income available to common
stockholders divided by the weighted average number of common shares outstanding
during the period. Diluted loss per share is calculated to reflect the potential
dilution that would occur if stock options or other contracts to issue common
stock were exercised and resulted in additional common stock that would share in
our earnings. Because of our net losses, the issuance of additional shares of
common stock under stock options and warrants or upon the conversion of
preferred stock would be antidilutive. The total number of common shares that
would have been used in our computation of diluted earnings per share if they
had been dilutive was 39,993,097 in 1999 and 31,436,512 in 1998.

YEAR 2000 READINESS DISCLOSURE STATEMENT

Our business operations were not adversely affected by any year 2000
issues. Prior to the end of 1999, we acted to ensure that our products and
critical internal business systems were year 2000 compliant, including forming a
company-wide task force, with representation from all major business units to
evaluate and manage the risks, solutions and cost associated with addressing
this issue. The Task Force identified all business systems, products and
services, including third party software we used in conjunction with our
products and implemented actions for the systems, products and services which
were not year 2000 compliant. Our Task Force developed and implemented a
strategy to minimize the impact of year 2000 technology problems. Our strategic
plan included regular reporting of progress to our management and board of
directors.

The costs incurred in addressing the year 2000 problem were expensed as
incurred in compliance with generally accepted accounting principles. None of
these costs were material to the results of operations in any one period.
Significant portions of the costs which were incurred were not incremental but
rather related to development efforts. However, we may incur significant costs
if unanticipated year 2000 compliance problems arise. These unanticipated costs,
or our failure to correct any unanticipated year 2000 problems in a timely
manner, could have a material adverse effect on our business, financial
condition, results of operations and prospects for growth.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities". This statement establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts and for hedging activities. This statement is
effective for financial statements for all fiscal quarters of all fiscal years
beginning after June 15, 2000. We intend to adopt this statement when required.
We are currently assessing the impact of this pronouncement on the Company.

In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements" ("SAB101"). In March 2000, the SEC
released SAB101A which defers reporting on the effects of the adoption of SAB
101 until the second fiscal quarter of 2000. The Company is evaluating the

39
41

implications of SAB 101 and to date nothing has been identified that would
significantly change the Company's historical practices with respect to the
events that trigger revenue recognition and the measurement of revenue.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK.

The foreign currency financial statements of our international operations
are translated into U.S. dollars at current exchange rates, except revenues,
costs and expenses, which are translated at average exchange rates during each
reporting period. Net exchange gains or losses resulting from the translation of
assets and liabilities are accumulated in a separate section of stockholders'
equity titled accumulated other comprehensive income. Therefore, our exposure to
foreign currency exchange rate risk occurs when translating the financial
results of our international operations to U.S. dollars in consolidation. At
this time, we do not use instruments to hedge our foreign exchange exposure
because the effect of foreign exchange rate fluctuations would not be material.
The net liabilities of our foreign operations at December 31, 1999 was
approximately $20.4 million.

For our operating locations in countries participating in the European
Union, the euro was adopted as their common legal currency effective January 1,
1999. We have not experienced any significant problems related to the euro
conversion and do not expect the euro conversion to have a material impact on
our results of operations.

We are exposed to market risk from changes in our investment securities
available for sale which consists entirely of our investment in BroadVision,
Inc. common stock. At December 31, 1999, our marketable securities were recorded
at fair value of approximately $62.8 million. Our investment in BroadVision,
Inc. common stock has exposure to price risk, which is estimated as the
potential loss in fair value due to a hypothetical change of 10% in quoted
market prices. This hypothetical change would reduce the carrying value of our
investment as well as our unrealized gain on investment securities available for
sale which is included as a component of stockholders' equity. This hypothetical
change would have an immaterial effect on the recorded value of our investment
securities available for sale.

Our only long term liabilities are capital lease obligations at a fixed
rate. Therefore, we do not believe there is any material exposure to market risk
changes in interest rates relating to current or long term liabilities.

S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1997, 1998 AND 1999

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business and Basis of Presentation

S1 Corporation develops integrated Internet software applications that
enable financial organizations to offer products, services and transactions over
the Internet in a secure environment. S1 Corporation also offers product
integration, training, call center technology and data center processing
services. On November 10, 1999, the shareholders of Security First Technologies
Corporation approved the name change of Security First Technologies Corporation
to S1 Corporation ("S1" or the "Company").

S1 operates in three business segments: Professional Services, Data Center
and Product Development. The Professional Services segment provides integration,
training, consulting and product enhancement services related to S1's software
products. The Product Development segment creates new products to supplement the
existing product suite. The Data Center segment provides processing and support
services to customers using S1's software products in the S1 data center. S1
manages the business based on these operating segments. The information
presented in the consolidated statements of operations reflects the revenues and
costs associated with these segments that management used to make operating
decisions and assess performance during 1999.

In the fourth quarter of 1999, the Company completed the acquisitions of
Edify Corporation ("Edify"), VerticalOne Corporation ("VerticalOne") and FICS
Group, N.V. ("FICS"). The results of operations of these companies are included
from the dates of acquisition (see further discussion in Note 2).

The consolidated financial statements include the accounts of S1
Corporation and its wholly owned subsidiaries. Significant intercompany accounts
and transactions have been eliminated in consolidation. In preparing the
consolidated financial statements, management is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and reported revenues and expenses during the reporting
periods. Actual results could differ from those estimates.

S1 Corporation is the successor company to Security First Network Bank
("SFNB") as a result of the reorganization completed on September 30, 1998. The
reorganization was accounted for in a manner similar to a pooling of interests
and, as a result, the historical financial statements of SFNB became the
historical financial statements of the Company. As more fully discussed in Note
13, the Company sold its banking operations on September 30, 1998, which have
been presented as discontinued operations for the years ended December 31, 1997
and 1998 in the accompanying consolidated financial statements.

The technology market for Internet related financial services is
characterized by significant risk as a result of rapid, evolving industry
standards, emerging competition and frequent new product and service
introductions. To a great extent, the Company's success is dependent on the
evolution of the technology markets for Internet related financial services and
on its successful implementation of technology for Internet related financial
services for certain large customers. Negative developments related to
technology for Internet related financial services or problems in
implementations for large customers could have an adverse impact on the
Company's financial position and results of operations.

Stockholders' equity, share and per share amounts for all periods presented
have been adjusted for a two-for-one stock split effected in the form of a stock
dividend paid on May 7, 1999 to holders of record on April 26, 1999.

Revenue Recognition and Deferred Revenues

The Company derives substantially all of its revenues from licensing
software, providing professional services, and providing data center processing
services.

For software license sales where no significant obligations remain, revenue
is recognized upon delivery of the software, provided collection is considered
probable, the fee is fixed or determinable, there is evidence of
49
51
S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

an arrangement, and vendor specific evidence exists to allocate the total fee to
all elements of the arrangement. When services are considered essential to the
functionality of the software, the software license and the related services are
recognized over the implementation period using the percentage of completion
method of accounting.

A portion of the Company's software license revenue is being recognized on
a straight-line basis over either the term of the agreement or, for contracts
without a term, the estimated period during which post-contract support is
expected to be provided. Under these arrangements, post-contract support and
maintenance were bundled as part of the license agreement and sufficient vendor
specific evidence did not exist to allocate the total fee to all elements of the
arrangement.

Revenues derived from contracts to provide services on a time and materials
basis are recognized as the related services are performed. Revenues from
professional services, provided on a fixed fee basis, are recognized using the
percentage of completion method, measured by the percentage of labor hours
incurred to date to estimated total labor hours for each contract. Provisions
for estimated losses on uncompleted contracts are made in the period in which
such losses are determined. Professional services revenues also include
reimbursable expenses and revenues from post-contract customer support and
maintenance. Revenues for post-contract customer support and maintenance are
recognized ratably over the contract period.

Data center processing revenues are recognized as the services are
performed, and are determined based on the number of end-users of the client
institutions during the period or based upon certain agreed upon contractual
minimum fees.

Deferred revenues represent payments received from customers for software
licenses or services in advance of revenue recognition.

Financial Instruments

Cash and cash equivalents include deposits with commercial banks with
original maturities of 90 days or less.

Investment securities consist entirely of marketable equity securities. The
investment securities are classified as available for sale and are reported at
fair value, with net unrealized gains or losses included as a component of
accumulated other comprehensive income in stockholders' equity. Unrealized
losses on all securities that are other than temporary are reported in the
statement of operations upon determination that the loss is other than
temporary. The specific identification method is used in determining gains and
losses on the sale of securities.

The Company uses financial instruments in the normal course of business.
The carrying values of accounts receivable, accounts payable, accrued expenses,
deferred revenues and notes payable approximate fair value due to the short-term
maturities of these assets and liabilities. The fair values of the Company's
investment securities available for sale are included in Note 3 and are based on
quoted market prices.

Property and Equipment

Property and equipment are carried at cost, less accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets
ranging from 1.5 to 5 years. Leasehold improvements are amortized using the
straight-line method over the estimated useful life of the improvement or the
lease term, whichever is shorter. Amortization of assets held under capital
lease arrangements is included in depreciation and amortization in the
consolidated statement of operations.

Product Development

Product development includes all research and development expenses and
software development costs. All research and development expenses are expensed
as incurred. The Company's policy is to expense all

50
52
S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

software development costs associated with establishing technological
feasibility, which the Company defines as completion of beta testing. Because of
the insignificant amount of costs incurred by the Company between completion of
beta testing and customer release, the Company has not capitalized any software
development costs in the accompanying consolidated financial statements.

Merger Related Costs

Merger related costs include expenses related to establishing the
infrastructure and consolidating the operations of acquired companies.

Intangible Assets and Goodwill

Intangible assets include purchased technology of $3.1 million at December
31, 1998 and $8.1 million at December 31, 1999, net of accumulated amortization
of $0.4 million and $2.1 million at December 31, 1998 and 1999, respectively.
Goodwill and other identifiable intangible assets, excluding purchased
technology, totaled $6.0 and $934.7 million at December 31, 1998 and 1999,
respectively, net of accumulated amortization of $5.8 million at December 31,
1998 and $45.9 million at December 31, 1999. Goodwill and other identifiable
intangible assets relate to the Company's acquisitions and are amortized over
their estimated useful lives (ranging from eight months to five years) using the
straight-line method. Purchased technology represents technology incorporated in
the Company's products and is amortized over the useful life of the purchased
technology (ranging from two to three years).

The Company evaluates the recoverability of intangible assets at the end of
each period or whenever events or changes in circumstances indicate that the
carrying amount should be assessed by comparing their carrying value to the
undiscounted estimated future net operating cash flows expected to be derived
from such assets. If such evaluation indicates a potential impairment, the
Company uses fair value in determining the amount of these intangible assets
that should be written off.

Stock Option Plans

The Company accounts for its stock option plans in accordance with the
provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees," and complies with the disclosure provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation." As such, compensation expense is recorded on the date
of grant only if the current market price of the underlying stock exceeds the
exercise price.

Loss Per Common Share

Basic loss per share is calculated as loss available to common stockholders
divided by the weighted average number of common shares outstanding during the
period. Diluted loss per share is calculated to reflect the potential dilution
that would occur if stock options or other contracts to issue common stock were
exercised and resulted in additional common stock that would share in the
earnings of the Company. Because of the Company's net losses, the issuance of
additional shares of common stock under stock options, warrants or upon the
conversion of preferred stock would be antidilutive. The total number of common
shares that would have been included in the Company's computation of diluted
loss per share if they had been dilutive was 24,936,556 in 1997, 31,436,512 in
1998 and 39,993,097 in 1999.

Income Taxes

The Company uses the asset and liability method of accounting for income
taxes, under which deferred income tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases and net operating loss and tax credit carryforwards.
Deferred income tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary

51
53
S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

differences are expected to be recovered or settled. The effect on deferred
income tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.

Foreign Currency Translation

The financial statements of the Company's international subsidiaries are
translated into U.S. dollars at current exchange rates, except for revenues and
expenses, which are translated at average exchange rates during each reporting
period. Currency transaction gains or losses, which are included in the results
of operations, are immaterial for all periods presented. Net exchange gains or
losses resulting from the translation of assets and liabilities are included as
a component of accumulated other comprehensive income in stockholders' equity.

Reclassifications

Certain amounts in the prior years' consolidated financial statements have
been reclassified to conform to the current year presentation.

2. BUSINESS ACQUISITIONS

During 1997, the Company expensed the unamortized balance of goodwill and
purchased technology resulting from the 1996 acquisitions of Five Paces, Inc.
("FPI") and SecureWare, Inc. ("SecureWare") of approximately $1.4 million, which
has been included in the amortization of acquisition intangible assets for the
year ended December 31, 1997. The Company made this assessment after determining
that there was limited future cash flows associated with the intangible assets
acquired.

On November 24, 1997, the Company completed the acquisition of Solutions By
Design, Inc. ("SBD"), a technology consulting firm. The Company exchanged
1,999,998 shares of restricted common stock with a value of approximately $5.7
million for all of the outstanding shares of SBD. The acquisition was accounted
for using the purchase method of accounting and, accordingly, the results of
operations of SBD have been included in the results of operations of the Company
since the effective date of the acquisition. Of the $6.2 million total purchase
price, which included common stock valued at $5.7 million and transaction costs
and liabilities assumed of $0.5 million, $4.2 million was assigned to
identifiable intangible assets and $2.0 million was assigned to goodwill. The
identifiable intangible assets include employment contracts, which were
amortized over the contract life of eight months, exclusivity and
non-solicitation agreements, which were amortized over the term of the contract
of 18 months, and assembled workforce, which is being amortized over three
years. The Company amortized goodwill over a period of two years, which was the
period that it will receive benefit from the projects that were developed by the
former SBD employees. Additionally, the Company has included $489,000 of
nonrecurring charges associated with the SBD acquisition in amortization of
acquisition intangible assets for the year ended December 31, 1997. These
amounts represent the premium paid to SBD by the Company for services rendered
during the fourth quarter of 1997 prior to consummation of the SBD acquisition.

On November 10, 1999, the Company completed the acquisitions of Edify and
VerticalOne. On November 18, 1999, the Company completed the acquisition of
FICS. All three acquisitions have been accounted for using the purchase method
of accounting with the excess of the purchase price over the estimated fair
value of the net assets recorded as goodwill. The consolidated financial
statements include the results of operations of Edify and VerticalOne from
November 1, 1999 and the results of operations of FICS from December 1, 1999.
The amounts allocated to in-process research and development were based on the
results of independent appraisals and were expensed upon acquisition because
technological feasibility had not been established and no future alternative
uses existed. Certain related core technology was valued as existing technology
and was not included in the value of the acquired in-process research and
development. The value of the purchased in-process research and development was
determined using an income approach. This approach involved estimating the
present value of the after-tax cash flows expected to be generated by the

52
54
S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

purchased in-process research and development, using risk-adjusted discount
rates and revenue forecasts as appropriate. Finally, a stage of completion
factor was applied to the sum of the present values of the cash flows in the
projection period. The stage of completion factor was calculated giving
consideration to the costs incurred to date on the in-process research and
development relative to the total anticipated costs for each project.

The Company issued 5,966,333 shares of common stock with a value of
approximately $313.5 million for all of the outstanding shares of Edify. The
Company also exchanged all outstanding options to purchase Edify stock into
1,319,044 options to purchase S1 common stock with an estimated fair value of
$64.7 million. Of the total purchase price of $381.7 million, which includes
$3.5 million of costs incurred directly related to the acquisition, $31.0
million was allocated to net assets acquired, $34.0 million to identifiable
intangible assets, $296.7 million to goodwill and $20.0 million to in-process
research and development. The liabilities assumed included approximately $2.0
million of employee termination costs, of which $0.8 million were unpaid at
December 31, 1999. The in-process research and development was expensed upon the
closing of the acquisition. Amounts allocated to goodwill, developed technology,
and customer lists are being amortized on a straight-line basis over three
years. The intangible asset related to the assembled work force is being
amortized on a straight-line basis over five years.

The Company issued 3,842,487 shares of common stock with a value of
approximately $144.0 million for all of the outstanding shares of VerticalOne.
Approximately, 186,360 of the total shares exchanged were issued to escrow in
connection with a general indemnity provision. If no claims arise that are
covered by this indemnity provision, the shares will be released after the
expiration of one year. These shares are included in the purchase price as they
do not relate to specific contingencies and it is not expected that any claims
will arise. The Company also exchanged all outstanding options to purchase
VerticalOne stock into 471,440 options to purchase S1 common stock with an
estimated fair value of $17.4 million. Of the total purchase price of $179.4
million, which includes $3.0 million of acquisition costs and $15.0 million of
preferred stock purchased before the closing of the acquisition, $23.4 million
was allocated to net assets acquired, $22.5 million to identifiable intangible
assets, $126.2 million to goodwill and $7.3 million to in-process research and
development. The in-process research and development was expensed upon the
closing of the acquisition. Amounts allocated to goodwill and developed
technology are being amortized on a straight-line basis over three years. The
intangible asset related to the assembled work force is being amortized on a
straight-line basis over five years.

The Company issued 10,000,000 shares of common stock with a value of
approximately $378.9 million to acquire all of the outstanding stock of FICS.
The Company also exchanged all outstanding options to purchase FICS stock into
1,149,638 options to purchase S1 common stock with an estimated fair value of
$42.4 million. Of the total purchase price of $426.1 million, which includes
$4.8 million of costs incurred directly related to the acquisition, $55.2
million was allocated to net liabilities acquired, $48.0 million to identifiable
intangible assets, $401.3 million to goodwill and $32.0 million to in-process
research and development. The liabilities assumed included approximately $0.5
million of lease termination costs related to the elimination of duplicate
facilities, which remained unpaid at December 31, 1999. Approximately $0.8
million of fixed assets with no future value as the result of the relocation of
certain facilities were written off in the purchase price allocation. A deferred
tax liability of $15.2 million was recognized for the difference between the
assigned values for book purposes and the tax bases of assets in accordance with
SFAS 109. The in-process research and development was expensed upon the closing
of the acquisition. Amounts allocated to goodwill, developed technology, and
customer list are being amortized on a straight-line basis over three years. The
intangible asset related to the assembled work force is being amortized on a
straight-line basis over five years.

FICS stockholders will also have the opportunity to earn up to an
additional 4,500,000 shares of S1 common stock through 2001 if certain operating
units meet revenue targets of $89 million and $123 million for the years ended
December 31, 2000 and 2001, respectively. FICS stockholders can earn up to one
half of the 4,500,000 shares by closing sales with specifically identified large
customers. These shares have not been

53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

included in the purchase price as they were not issuable at the time of the
acquisition. The purchase price will be adjusted when and if these shares become
issuable.

The Company plans to sell the Financial Reporting Systems ("FRS") segment
of the FICS business. The expected proceeds from the sale of the FRS segment and
the projected net cash used by the FRS business during the holding period, which
is expected to be one year, were taken into consideration in the purchase price
allocation. Approximately $10.6 million of the total purchase price was
allocated to identifiable intangible assets and approximately $1.0 million was
allocated to goodwill. These amounts are included in the total purchase price of
FICS. The operating loss of the FRS business excluded from the consolidated
operating results of the Company for the year ended December 31, 1999 was $0.3
million.

The following unaudited pro forma summary presents information as if the
Edify, VerticalOne and FICS acquisitions occurred at the beginning of fiscal
year 1998. The proforma consolidated results are based on historical information
and include the impact of certain adjustments, including amortization of
intangibles. The proforma information is not necessarily indicative of what
actually would have occurred if the acquisitions had been in effect at the
beginning of fiscal year 1998 and it is not necessarily indicative of future
results from operations of the combined company.

During 1998, the Company terminated a data center facilities management
agreement and, as a result, purchased approximately $1.8 million of computer
equipment. Immediately thereafter, the Company entered into a sale-leaseback
arrangement for this computer equipment with a third party which is accounted
for as a capital lease. The Company recorded a charge which has been included in
depreciation and amortization of approximately $1.2 million to adjust the
carrying value of the leased computer equipment to its fair market value.
Additionally, the Company recorded a write-down of computer equipment of $0.5
million in 1998 to reflect the results of a physical inventory of computer
equipment. At December 31, 1999, approximately $3.6 million of total property
and equipment is located outside of the United States.

Accounts Receivable

Included in accounts receivable are unbilled receivables of approximately
$0.7 million and $16.6 million at December 31, 1998 and 1999, respectively. The
unbilled receivables are comprised primarily of revenue recognized on contracts
for which billings have not been presented under the terms of the contracts at
the balance sheet dates. It is anticipated that such unbilled amounts at
December 31, 1999 will be received upon presentment of billings or completion of
contracts. Substantially all unbilled amounts are expected to be collected
within six months.

At December 31, 1999, one customer represented 26% of total receivables.

The Company had two bank notes outstanding secured by equipment at December
31, 1999. They consisted of a note with a balance of $0.4 million due on January
1, 2002 bearing interest at the prime interest rate plus 2% and a note with a
balance of $1.6 million due on July 10, 2002 bearing interest at the prime
interest rate plus 1.5%. The Company is required to maintain certain financial
covenants. As a result of non-compliance with the covenants at December 31,
1999, the notes are classified as short-term.

The remaining notes payable of approximately $4.4 million consist of lines
of credit with various banks with interest rates ranging from 3.86% to 7%. The
weighted average interest rate at December 31, 1999 was 4.15%. The lines of
credit are due upon demand and are classified as short-term. At December 31,

6. STOCKHOLDERS' EQUITY

Preferred Stock

The Company has authorized 25,000,000 shares of $0.01 par value preferred
stock, of which 1,637,832 shares have been designated as Series A Convertible
Preferred Stock ("Series A"), 749,064 shares have been designated as Series B
Redeemable Convertible Preferred Stock ("Series B") and 215,000 shares have been
designated as Series C Redeemable Convertible Preferred Stock ("Series C"). The
terms of the Series A, Series B and Series C (collectively the "Preferred
Stock") provide the holders with identical rights to common stockholders with
respect to dividends and distributions in the event of liquidation, dissolution,
or winding up of the Company. Series C is non-voting and except as described
below, Series A and Series B are nonvoting. Each series is entitled to vote as a
single class on the following matters: (i) any amendment to any charter
provision that would change the specific terms of that series which would
adversely affect the rights of the holders of that series and (ii) the merger or
consolidation of the Company with another corporation or the sale, lease, or
conveyance (other than by mortgage or pledge) of the properties or business of
the Company in exchange for securities of another corporation if Series A or
Series B is to be exchanged for securities of such other corporation and if the
terms of such securities are less favorable in any respect. Action requiring the
separate approval of the Series A and Series B stockholders requires the
approval of two-thirds of the shares of Series A and Series B then outstanding
voting as a separate class. In addition, holders of the Series A and Series B
are entitled to vote with the holders of common stock as if a single class, on
any voluntary dissolution or liquidation of the Company. Holders of Series B
also are entitled to vote with the holders of the common stock on any merger,
acquisition, consolidation or other business combination involving the Company
and the sale, lease or conveyance other than by mortgage or pledge of all or
substantially all of the Company's assets or properties. When the Series A votes
with the common stock on a dissolution or liquidation, each share of Series A is
entitled to one vote. When the Series B is entitled to vote with the common
stock, the holders of Series B are entitled to the number of votes equal to the
number of shares of common stock into which the Series B could be converted.
Subject to certain limitations related to ownership, each share of Series A is
convertible into two shares of common stock at the option of the holder. The
749,064 shares of Series B preferred are convertible at the option of the holder
after October 1, 2000 into 1,070,090 shares of common stock based on a
conversion price of $9.345. The number of shares of common stock into which the
Series A preferred and Series B preferred are convertible is subject to
adjustment. The Series B preferred is redeemable at the option of the Company
through September 2000 by paying the holder $10,000,000 plus interest.

Equity Transactions

During 1997, the Company sold 1,139,956 shares of common stock and 159,952
shares of Class A convertible preferred stock for approximately $6 million.

During 1998, the Company sold 185,186 shares of common stock for
approximately $1 million and 749,064 shares of Series B convertible redeemable
preferred stock for approximately $10 million.

In 1998, the Company entered into a relationship with BroadVision, Inc.
("BroadVision") whereby the Company exchanged 363,220 shares of the Company's
common stock worth $2.0 million for a software license and prepaid royalty
agreement which gives the Company the right to resell the software by
integrating the software with S1's software products. In addition, the Company
exchanged 259,404 shares of common stock valued at $1.8 million for 369,003
shares of BroadVision.

As part of the sale of the banking operations to Royal Bank of Canada
("Royal Bank"), the Company issued to Royal Bank four separate options to
purchase up to an aggregate $10.0 million in capital stock of the Company. In
1998, Royal Bank exercised the first option for 420,876 shares at an exercise
price of $5.94 per share. In 1999, Royal Bank exercised options to purchase
382,614 shares at $6.53 per share and 347,831 shares at $7.19 per share. The
fourth option for 316,232 with a per share exercise price of $7.91 expires in
June 2000 and remains outstanding at December 31, 1999.

S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

On February 19, 1999, S1 entered into strategic alliances with
Hewlett-Packard and Andersen Consulting. As part of these alliances,
Hewlett-Packard agreed to make a $10.0 million equity investment in the
Company's common stock and Andersen Consulting agreed to make a $4.0 million
equity investment in the Company's common stock. The stock sales closed as of
April 30, 1999, with the Company issuing 254,804 shares of common stock. On
February 19, 1999, Andersen Consulting received warrants to purchase up to an
additional 200,000 shares of S1 common stock at $54.94 per share. The warrants
will vest, if at all, in three installments of 40,000, 80,000 and 80,000 shares
only if the Company enters into agreements to sell its services or license its
products to specified customers as a result of its relationship with Andersen
Consulting. The warrants expire in February 2001. Vested warrants expire two
years from the vesting date. At December 31, 1999, 200,000 warrants were
outstanding and none were exercisable. The Company expects to record a non-cash
charge for the fair value of each warrant installment earned. This charge will
be measured at the reporting date in which the target to earn a warrant
installment is achieved. As of December 31, 1999, the Company has not recorded
any charge under the terms of the warrants.

On February 25, 1999, the Company entered into an agreement with Royal Bank
under which Royal Bank purchased additional software modules and agreed to
implement certain applications within S1's Consumer Suite. Royal Bank has agreed
to pay $50.0 million to the Company over the next five years on the following
schedule: the first $5.0 million was due to be paid no later than February 2000
with the remaining amount to be paid equally over a four year period after Royal
Bank has implemented S1's software. Royal Bank paid S1 $5.0 million to satisfy
the first installment. If Royal Bank terminates its minimum payment obligation,
it is required to pay a termination fee equal to 40% of the unpaid amount. In
connection with this agreement, the Company issued 215,000 shares of newly
designated Series C redeemable convertible preferred stock. The Company recorded
a subscription receivable of $12.0 million, the estimated fair value of the
preferred stock at issuance, and will reduce such subscription receivable,
including imputed interest, as the payments under the arrangement are received.
The right to convert Series C on a two-for-one basis (post-split) into the
Company's common stock will vest, if at all, in five installments based upon the
payment schedule in the agreement. On February 25, 2000, the first installment
of 21,500 shares vested and became convertible. The remaining four installments
each comprised of 48,375 shares, will vest and become convertible if Royal Bank
has paid minimum fees of $11,250,000 per year for the first four years following
the completion date of the implementation. If the minimum fees paid by Royal
Bank at any anniversary date of the completed implementation exceed the minimum
fee level for the next anniversary date, Royal Bank may elect to vest in the
next installment of shares. The right to convert Series C into common stock
expires ninety days after the vesting date. Any shares of Series C that do not
vest and become convertible into shares of common stock on or before March 31,
2004 become mandatorily redeemable by the Company for an amount equal to $0.01
per share. At December 31, 1999, no shares of Series C were vested and
convertible.

On February 25, 1999, Royal Bank was granted a warrant to purchase 800,000
shares of common stock at a price of $30.00 per share. The warrant will vest in
four equal installments if, as of four annual measurement dates, beginning one
year after the completion of the implementation of certain applications within
S1's Consumer Suite, Royal Bank has an additional one million end-users using
the S1 software. Each installment terminates if the targeted customer levels are
not achieved or if an installment vests, the warrant terminates ninety days
after the vesting date. At December 31, 1999, 800,000 warrants were outstanding
and none were exercisable. The Company expects to record a non-cash charge for
the fair value of the warrants on the date when the warrants become exercisable.

On May 16, 1999, S1 and Intuit entered into a Stock Purchase and Option
Agreement pursuant to which Intuit purchased 970,813 shares of S1 common stock
for $50.0 million. S1 also granted Intuit options to purchase 3,629,187 and
950,000 shares of S1 common stock that vested upon the closing of the Edify and
FICS acquisitions, respectively. Intuit was granted 445,000 additional options
to purchase S1 common stock that may become exercisable based on the achievement
of certain earn-out targets for FICS. All of the Intuit options were granted
with an exercise price of $51.50 per share and expire on November 10, 2004. At
December 31, 1999, 5,024,187 of these options were outstanding and 4,579,187
were exercisable. Concurrent
57

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

with the Stock Purchase and Option Agreement, the Company and Intuit entered
into a five-year cross-license and distribution agreement. Under the terms of
the cross-license agreement, Intuit and the Company agreed to exchange
technologies to enable delivery of interactive financial management software and
Internet based financial tools. This agreement is considered a non-monetary
exchange in accordance with APB 29 and accordingly, has not been given any
recognition in the consolidated financial statements. Under the distribution
agreement, the Company has a license to distribute Intuit products and services
and will receive a royalty fee on such sales. There was no significant activity
under the distribution agreement during 1999.

On December 23, 1999, S1 granted a vested, immediately exercisable warrant
to purchase 84,994 shares of S1 common stock at $80.00 per share in connection
with a pilot project and distribution agreement between a third party and a
subsidiary of S1. At December 31, 1999, the warrant was outstanding and
exercisable. The warrant expires on December 23, 2004. The fair value of the
warrant of $5.4 million is being expensed over the term of the agreement which
is approximately 60 days. The Company recorded $715,000 of expense in the year
ended December 31, 1999.

7. INCOME TAXES

The Company has not recorded an income tax benefit for 1997, 1998 or 1999
because operating losses were incurred and a valuation allowance has been
recorded against substantially all of its net deferred income tax assets,
primarily comprised of net operating loss carryforwards.

A reconciliation of the provision for income taxes to the amount computed
by applying the statutory federal income tax rate to loss from continuing
operations is as follows:

The income tax effects of the temporary differences that give rise to the
Company's deferred income tax assets and liabilities as of December 31, 1998 and
1999 are as follows:

======== ========


The valuation allowance increased $9.9 million, $10.9 million and $27.7
million during the years ended December 31, 1997, 1998 and 1999, respectively.
Deferred income tax assets and liabilities are recognized for differences
between the financial statement carrying amounts and the tax bases of assets and
liabilities which will result in future deductible or taxable amounts and for
net operating loss and tax credit carryforwards. A valuation allowance is then
established to reduce the deferred income tax assets to the level at which it is
"more likely than not" that the tax benefits will be realized. Realization of
tax benefits of deductible temporary differences and operating loss and tax
credit carryforwards depends on having sufficient taxable income within the
carryback and carryforward periods. Sources of taxable income that may allow for
the realization of tax benefits include (1) taxable income in the current year
or prior years that is available through carryback, (2) future taxable income
that will result from the reversal of existing taxable temporary differences,
and (3) future taxable income generated by future operations. Because of the
uncertainties with respect to the Company's ability to achieve and sustain
profitable operations in the future, the Company has recorded a valuation
allowance to offset substantially all of its net deferred income tax assets.

During 1999, the Company acquired VerticalOne, Edify and FICS which
resulted in establishing identifiable intangibles of $22.5 million, $34.0
million and $48.0 million, respectively. The identifiable intangibles created
the $39.1 million deferred tax liability included in the table of deferred taxes
above. The Company acquired net operating loss carryforwards in the Edify and
FICS transactions of approximately $18.3 million and $45.3 million,
respectively. The Company established a valuation allowance relating to the FICS
carryforwards of $15.2 million. If the benefit from these net operating loss
carryforwards is realized, the Company will reduce goodwill recorded in
connection with the FICS transaction. The net operating loss carryforwards for
which a valuation allowance was not established were utilized to offset the
deferred tax liabilities created by the identifiable intangibles.

S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

As shown in the table of deferred taxes above, the deferred income tax
liability related to the unrealized gain on investment securities available for
sale is offset against the Company's deferred tax assets. The resulting credit
from the reversal of the valuation allowance is recorded in the consolidated
statement of stockholders' equity and comprehensive income (loss).

At December 31, 1999, the Company has domestic and foreign net operating
loss carryforwards and tax credit carryforwards of approximately $163.5 million,
$43.8 million and $3.7 million, respectively. The domestic net operating loss
carryforwards expire at various dates through 2019 unless utilized, the foreign
net operating loss carryforwards generally do not expire and the tax credit
carryforwards expire at various dates through 2019. The Company's domestic net
operating loss carryforwards at December 31, 1999 include $87.1 million in
income tax deductions related to stock options which will be reflected as a
credit to additional paid-in capital when realized. The acquisitions of
VerticalOne, Edify and FICS created ownership changes for federal tax purposes.
The result of an ownership change is to limit a company's ability to utilize its
net operating loss and credit carryforwards based on the valuation of the
company. Due to the value of the companies at the time of their respective
ownership change, the limitation of net operating loss and credit carryforwards
is not expected to be meaningful.

8. COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company and its subsidiaries lease office facilities and computer
equipment under non-cancelable operating lease agreements, which expire at
various dates through 2013. Total rental expense under these leases was
$1,004,000, $1,638,000 and $5,817,000 in 1997, 1998 and 1999, respectively.
Future minimum annual payments under non-cancelable operating lease agreements
are as follows:

Cash Held in Escrow

At December 31, 1999, the Company had $501,000 in cash in an escrow account
that was established as a result of the termination of a data center facilities
management agreement. This amount is included in cash and cash equivalents. The
amount required to be held in escrow will be reduced by $250,000 each year
following the termination, provided there have been no indemnification claims.

At December 31, 1999, the Company had approximately $98,000 cash on deposit
with a bank to guarantee certain rent payments.

Intellectual Property Settlement

In November 1998, Edify entered into an agreement with Lucent Technologies
Inc. ("Lucent") under which each company released the other from claims of past
infringement and settled patent disputes that had been ongoing since 1996. Under
the agreement, Edify agreed to pay Lucent a minimum annual royalty fee of
approximately $500,000 up to a maximum of approximately $700,000 in each of the
fiscal years from 1999 to 2004. In addition, in fiscal years 2005 and 2006, if
Edify exceeds certain targets that are specified in the Lucent agreement, the
Company will be required to pay additional amounts.

Contractual Commitments

In the normal course of business, the Company enters into contracts with
customers. These contracts contain commitments including, but not limited to,
minimum standards and time frames against which the Company's performance is
measured. In the event the Company does not meet its contractual commitments
with its customers, the Company may incur penalties and/or certain customers may
have the right to terminate their contracts with the Company. The Company does
not believe that it will fail to meet its contractual commitments to an extent
that will result in a material adverse effect on its financial position or
results of operations.

Litigation

The Company is involved in litigation incidental to its business. In the
opinion of management, after consultation with legal counsel, the ultimate
outcome of such litigation will not have a material adverse effect on the
Company's financial position, results of operations or cash flows.

9. STOCK OPTION PLANS

The Company maintains certain stock option plans providing for the grant of
stock options to officers, directors and employees. The plans provide for
21,117,000 shares of the Company's common stock to be reserved for issuance
under the plans. Substantially all stock options granted under the plans have
ten-year terms and generally vest and become exercisable ratably over four years
from the date of grant. At December 31, 1999, there were 4,660,000 shares
available for future grants under the plans.

In connection with the acquisitions of Edify, VerticalOne and FICS, the
Company exchanged 1,319,044, 471,440 and 1,149,638 options to purchase shares of
S1 common stock, respectively, for all the outstanding options of Edify,
VerticalOne and FICS. The fair value of these options was included in the
purchase price. In conjunction with the merger agreements, approximately
3,160,000 new options were granted to employees of Edify, FICS and VerticalOne.

During 1999, the Company granted approximately 1,450,000 stock options
which will fully vest at the end of five years with accelerated vesting based on
the achievement of certain performance targets during fiscal years 1999 through
2002. Two performance goals are in place for each of these years. For each
performance target achieved, 12.5% of the options will vest in the year
following the achievement of the target. Vesting related to performance targets
not met may be earned in subsequent years.

Upon the acquisition of SBD, the Company granted 550,000 stock options to
the former SBD employees which became exercisable upon the achievement of
certain performance and software development goals during 1998 and 1999.

For stock options granted where the exercise price was less than the market
price of the stock on the date of grant, the per share weighted-average exercise
price was $0.52 and $38.38 and the per share weighted average fair value was
$3.30 and $43.76 for stock options granted during 1998 and 1999, respectively.
For stock options granted where the exercise price equaled the market price of
the stock on the date of grant, the per share weighted-average exercise price
was $3.28, $4.21, and $35.05 and the per share weighted-average fair value was
$2.17, $4.04, and $32.73 for stock options granted during 1997, 1998, and 1999,
respectively. The fair values were determined using the Black Scholes
option-pricing model with the following weighted-average assumptions: expected
dividend yield of -0-%, risk-free interest rate of 5.2% in 1997 and 1998 and
5.8% in 1999, expected volatility of 79.2% in 1997, 94.2% in 1998 and 102.0% in
1999, and an expected life of 10 years.

The Company applies APB Opinion No. 25 in accounting for its stock option
plans and, accordingly, compensation cost in the amount of approximately $0.7
million, $2.0 (including approximately $0.5 million included in discontinued
operations) and $1.1 million has been recognized in 1997, 1998, and 1999,
respectively, relating to stock options granted with exercise prices less than
the market price. Had the Company determined compensation cost based on the fair
value at the grant date for its stock options under

10. EMPLOYEE BENEFIT PLANS

401(k) Plan

The Company provides a 401(k) Retirement Savings Plan (the "Plan") for
substantially all of its full-time employees in the United States. Benefit plans
of acquired companies will be merged with the Company's plan and all full-time
employees will be included in the Company's plan. Each participant in the Plan
may elect to contribute from 1% to 15% of his or her annual compensation to the
Plan. The Company, at its discretion, may make matching contributions to the
Plan. The Company is currently matching up to 4% of the employees compensation,
first to the Company's stock fund $1 for each dollar contributed by the employee
and second to the remaining investment funds $.25 for each dollar contributed by
the employee. Beginning January 1, 2000, the Company's discretionary match will
change to 100% of the Company's stock fund, up to 4% of the employees'
compensation. The Company's contributions to the Plan charged to expense for
1997, 1998 and 1999 were approximately $171,000, $286,000 and $526,000,
respectively.

Employee Stock Purchase Plan

Under the Company's Employee Stock Purchase Plan (ESPP), each employee of
the Company who is customarily employed at least twenty hours per week over a
five month period, is eligible to purchase the Company's common stock at a 15%
discount. The ESPP was adopted during 1999 and there were no shares issued under
the plan as of December 31, 1999.

11. MAJOR CUSTOMERS AND INTERNATIONAL REVENUES

Major Customers

For the year ended December 31, 1997, two customers represented 18% and 10%
of total revenues, respectively. For the year ended December 31, 1998, two
customers represented 39% and 12% of total revenues, respectively. For the year
ended December 31, 1999, two customers represented 40% and 12% of total
revenues, respectively. Revenue from one customer was greater than 10% of total
revenues in all three years.

International Revenues

Revenues from international customers represented 19%, 7% and 12% of total
revenues for the years ended December 31, 1997, 1998 and 1999, respectively.

12. RELATED PARTY TRANSACTIONS

During the latter part of 1996, among its ordinary course of research and
development activities, the Company started a project known as "WebTone". After
the assessment phase of the WebTone project was completed, the board of
directors determined not to proceed with the WebTone project. With the board's
full knowledge and agreement, the former Chairman of the board of SFNB, Michael
C. McChesney, created and funded his own company to develop WebTone. In
undertaking these activities, Mr. McChesney and the board agreed to enter into
some form of arrangement for a future business relationship.

In June 1999, the Company and WebTone reached an agreement whereby WebTone
issued common stock to the Company in return for the cancellation of the
outstanding receivable and other expenses incurred by the Company during the
period the project was sponsored by S1, resulting in a 3% investment in WebTone.
The agreement allows for settlement of future receivables in cash or WebTone
stock based on fair market value as determined by WebTone Board of Directors, at
the discretion of the Company.

S1 CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

In November 1999, the Company entered into a three-year license and
reseller agreement with WebTone whereby the Company received a license to use
the WebTone software for internal purposes and to resell to its customers. In
exchange, WebTone received a license to market and demonstrate the S1 software
to its customers. This agreement is considered a non-monetary exchange in
accordance with APB 29 and accordingly, has not been given any accounting
recognition in the consolidated financial statements. There was no significant
activity under this agreement during 1999.

The Company performed certain administrative and technical services for
WebTone amounting to approximately $80,000 in 1997, $192,000 in 1998 and $47,000
in 1999. The Company's current President and Chief Executive Officer is on the
Board of Directors of WebTone. As of December 31, 1998 and 1999, respectively,
the Company had a receivable from WebTone related to these services of $173,000
and $90,000.

During 1998 and 1999, the Company paid a technology consulting company,
McCall Consulting Group, approximately $1.1 million and $3.0 million,
respectively for consulting services. As of December 31, 1998 and 1999, S1 has a
payable to McCall Consulting Group of $282,000 and $91,000, respectively. The
president of McCall Consulting Group is a director of the Company.

In February 1999, S1 and Andersen Consulting LLP entered into a strategic
partnership. S1 issued a warrant to purchase 200,000 shares of S1 common stock
to Andersen Consulting in February. The number of shares represented by the
warrant is adjusted to reflect the May 1999 two-for-one split of S1's common
stock. In April 1999, S1 issued 72,800 shares of S1 common stock to an affiliate
of Andersen Consulting. In 1999, S1 and Andersen Consulting paid each other for
work done on contracts where the other entity was the primary contractor. S1
paid Andersen Consulting a total of $10.0 million for such work and Andersen
Consulting paid S1 a total of $627,000. Jackson L. Wilson, Jr., a director of
S1, is a member of the Executive Committee of Andersen Consulting. At December
31, 1999, the accounts receivable due from Andersen was $270,000.

13. DISCONTINUED OPERATIONS

On September 30, 1998, the Company completed the sale of its banking
operations to the Royal Bank, through one of its U.S. based subsidiaries. Royal
Bank paid $3 million in excess of the net assets sold less a $1.5 million
holdback for indemnification which will be received eighteen months from the
closing date and is shown as a note receivable in the 1998 and 1999 consolidated
balance sheets. The banking operations included substantially all of the loans
and investment securities and deposit relationships of SFNB and were legally
separated from the technology operations through the formation of a holding
company. The Company recorded a gain of $812,000 on the sale of the banking
operations which included a $1.3 million charge related to the estimated fair
value of options to purchase the Company's capital stock issued to Royal Bank in
connection with the sale of the banking operations.

The losses from the banking operations are reflected in the accompanying
consolidated statements of operations as discontinued operations. Net interest
income for the nine month period ended September 30, 1998 was $1.3 million and
the net loss, excluding the gain on disposal, was $3.1 million.

In addition to the sale of the banking operations, the Company entered into
technology licensing and consulting arrangements with Royal Bank for $6 million,
which were effective September 30, 1998.

14. SUBSEQUENT EVENTS

On January 18, 2000, the Company entered into a merger agreement with
Davidge Data Systems, Inc., a provider of order routing services to brokerage
firms. The acquisition is expected to be completed in the second quarter of 2000
and will be accounted for as a purchase.

On March 1, 2000, the Company entered into a 10-year lease in a new
building complex located in Atlanta, Georgia. The building is expected to be
completed in late 2001.

The service of directors and officers prior to May 1998 was as a director
or officer of Security First Network Bank, the former parent of S1. Security
First Network Bank was a wholly owned subsidiary of Cardinal Bancshares, Inc.
until May 1996. In connection with S1's acquisition of FICS Group N.V. in
November 1999, S1 agreed to appoint Mr. Akkermans and Mr. Hodgson to three-year
terms on the S1 Board of Directors. As part of S1's November 1999 acquisition of
VerticalOne Corporation, S1 agreed to appoint Mr. Freishtat to a three-year term
on the S1 Board.

Provided below is a brief description of the principal occupation of each
of our directors and executive officers for the past five years. The executive
officers are elected by the board to serve a one-year term.

James S. Mahan, III has served as a director and as Chief Executive Officer
since 1995 and as President since June 1998. He served as Chairman of the Board

In connection with S1's acquisition of VerticalOne, S1 granted Gregg

to a Letter Agreement, dated as of September 23, 1999, by and between S1 and Mr.
Freishtat, the options will vest 25% annually, with the first vesting date being
September 23, 2000. The Letter Agreement also provides that 50% of any unvested
options will accelerate and become exercisable as of the effective date of any
change of control of S1. FICS Group N.V. entered into a

72
74

Management Agreement with Michel Akkermans and Pamica N.V. on December 4, 1998.
FICS was acquired by S1 in November 1999. Mr. Akkermans is a director of S1 and
Pamica is an entity controlled by him. In this section, we refer to Mr.
Akkermans and Pamica as the managers. Under the agreement, the managers are
responsible for the daily management of FICS. For 1999, FICS paid approximately
$360,150 to the managers, as established by the FICS Board of Directors. The
agreement provides for normal fringe benefits, home office support and
reimbursement of company expenses incurred by the managers. It contains
provisions that restrict that ability of the managers to compete with FICS
during the term of the agreement and for two years after termination. The
agreement is for an unlimited duration and may be terminated by a party with six
months advance notice. Immediate termination is permitted only in the case of a
serious breach, which is defined to include dishonesty, fraud, indictable
offenses and acts which bring FICS into disrepute. In the event of a termination
by FICS other than in the case of a serious breach, the agreement provides for
the payment of a one time indemnity in an amount equal to the total of the
amount paid to the managers in the preceding twelve months.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Since 1996 through the corporate reorganization of Security First Network
Bank in September 1998, the full Board of Directors of Security First Network
Bank served as a compensation committee. In the fourth quarter of 1998, a
separate compensation committee of the S1 Board was established. The current
Chairman of the compensation committee is Mr. Wilson and the other members are
Mr. Gardner, Mr. Hodgson, and Mr. Runnion. The compensation committee recommends
to the full board of directors, which has ultimate responsibility over
compensation matters. Set forth below is a report of the compensation committee
addressing S1's compensation policies for fiscal year 1999 as they affected our
executive officers.

Compensation Policies for Executive Officers. S1's executive compensation
policies are designed to provide competitive levels of compensation, to assist
S1 in attracting and retaining qualified executives and to encourage superior
performance. In determining levels of executive officers' overall compensation,
the qualifications and experience of the persons concerned, the size of the
company and the complexity of its operation, the financial condition, including
revenues, the compensation paid to other persons employed by the company and the
compensation paid to persons having similar duties and responsibilities in the
technology industry were considered. Compensation paid to our executive officers
in 1999 consisted of the following components: base salary, long-term incentives
(awards of stock options) and participation in S1's other employee benefit
plans. No bonuses were paid to executive officers for 1999. While each of these
components has a separate purpose and may have a different relative value to the
total, a significant portion of the total compensation package for 1999 for the
executive officers is highly dependent on the public market value of S1 and
total return to shareholders. Our executive officers have significant equity
interests in S1's success by virtue of stock-based compensation.

Base Salary. Base salary is intended to signal the internal value of the
position. In establishing the 1999 salary for each executive officer, the
officer's responsibilities, qualifications and experience were considered. None
of our executive officers received an increase in base salary for 1999. Base
salaries for 2000 have increased to provide a competitive level of compensation.
The 2000 base salaries for our named executive officers are as follows: Mr.
Mahan, $350,000; Mr. Akkermans, $360,150; Mr. Drechsel, $265,000; and Mr.
Stockwell, $185,000.

Long-Term Incentive Compensation. S1 uses stock options to provide
long-term incentive compensation. The compensation committee endorses the
position that stock ownership by management is beneficial in aligning
management's and shareholders' interests in the enhancement of shareholder
value. The purpose of stock option awards is to provide an opportunity for the
recipients to acquire or increase a proprietary interest in S1, thereby creating
a stronger incentive to expend maximum effort for the long-term growth and
success of S1 and encouraging recipients to remain in the employ of S1. Officers
and other full-time employees of S1 and its subsidiaries are eligible for grants
under our 1995 and 1997 stock option plans. Stock options are normally

74
76

granted each year with the size of the grants generally tied to and weighted
approximately equally based on an officer's responsibility level and
performance. During 1999, 1,720,000 stock options were granted to our executive
officers, as adjusted to reflect the May 1999 two-for-one split of our common
stock.

Other. In addition to the compensation paid to executive officers
described above, executive officers received, along with and on the same terms
as other employees, certain benefits such as health insurance and participation
in S1's 401(k) Plan participation in S1's Employee Stock Purchase Plan. Mr.
Akkermans only received health insurance benefits in 1999.

CEO Compensation. Since the company began its current Internet business in
1995, the compensation for the Chief Executive Officer has been primarily cash
compensation in the form of a base salary and stock-based in the form of
options. In 1999, the Chief Executive Officer's 1999 base salary was $200,000,
which was the same as his 1998 and 1997 base salary. The Chief Executive Officer
did not receive a bonus in 1997, 1998 or 1999 or an award of stock options in
1997 or 1998. In January 1999, the Chief Executive Officer was awarded options
to purchase 400,000 shares of S1 common stock that vest upon the earlier of the
satisfaction of certain performance criteria for S1 or five years. Also, in
December 1999, the Chief Executive Officer was granted options to purchase
1,000,000 shares of common stock in recognition of the successful strategic
alliances entered into during 1999 between S1 and Andersen Consulting LLP,
Hewlett-Packard Company and Intuit Inc. and the completion of S1's acquisitions
of Edify Corporation, VerticalOne Corporation and FICS Group N.V. As noted
above, a significant portion of S1's total compensation package is highly
dependent on the public market value of S1 and total return to shareholders.
This has been the case since the company began its operations as an Internet
business in 1995. The public market value of S1 common stock increased
significantly during 1999, thereby considerably enhancing the value of long-term
stock awards granted to the Chief Executive Officer in fiscal 1999 and in
previous years. At the beginning of 1999, the reported per share closing price
of our common stock was $15.313, as adjusted for the May 1999 two-for-one split
of our common stock. At year-end 1999, it was $78.125.

Internal Revenue Code Section 162(m). In 1993, the Internal Revenue Code
of 1986, as amended, was amended to disallow publicly traded companies from
receiving a tax deduction on compensation paid to executive officers in excess
of $1 million (section 162(m) of the Code), unless, among other things, the
compensation meets the requirements for performance-based compensation. S1 did
not take this limitation into account prior to fiscal 1999 in structuring most
of its equity compensation programs and in determining executive compensation.
The compensation committee considered the deductibility limit for compensation
when awarding equity-based compensation beginning in fiscal 1999. Our Amended
and Restated 1995 Stock Option Plan contains provisions to allow option grants
to qualify for an exemption from that limit.

PERFORMANCE OF OUR COMMON STOCK

The following table sets forth comparative information regarding the
cumulative shareholder return on our common stock since May 26, 1996. Share
information from May 26, 1996 to September 30, 1998 is based on the common stock
of Security First Network Bank, the former parent of Security First Technologies
Corporation. From September 30, 1998 to November 10, 1999, our company name was
Security First Technologies Corporation. Since November 10, 1999, our name has
been S1 Corporation. Total shareholder return is measured by dividing cumulative
dividends for the measurement period (assuming dividend reinvestment) plus share
price change for the period by the share price at the beginning of the
measurement period. Neither S1 nor Security First Network Bank has paid
dividends on its common stock from May 26, 1996 to December 31, 1999. Our
cumulative shareholder return over this period is based on an investment of
75
77

$100 on May 26, 1996 and is compared to the cumulative total return of the
Interactive Week Internet Index and the Nasdaq Composite Index.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

During 1999, S1 used software development consulting services from McCall
Consulting Group. The President of McCall Consulting, Mr. Joseph S. McCall, is
one of our directors. During 1999, the total amount paid to McCall Consulting
was approximately $3.0 million. At December 31, 1999, S1 had outstanding
payables to McCall Consulting of $91,000.

During the latter part of 1996, among its ordinary course of research and
development activities, S1 started a project known as "WebTone." The WebTone
project was established to assess the customer care issues raised as a result of
interacting with retail customers over new delivery channels and subsequently to
develop software solutions to resolve such issues more efficiently. In November
1997, after the assessment phase of the project was completed at a cost of
approximately $300,000, the board of directors of Security First Network Bank,
the predecessor public company of S1, determined not to proceed with WebTone,
primarily because of the SFNB board's uncertainty regarding the potential of
such a project and because of limited resources, both capital and personnel.
With the SFNB board's full knowledge and agreement, the former Chairman of the
Board of SFNB, Michael C. McChesney, created and funded his own company to
develop WebTone. In undertaking these activities, Mr. McChesney and the board of
directors agreed that WebTone and Mr. McChesney should enter into some form of
arrangement for a future business relationship.

In 1999, S1 engaged in transactions with WebTone and Mr. McChesney resigned
as Chairman of the Board of S1 in February 1999. James S. Mahan, III, a
Director, President and Chief Executive of S1 is on the Board of Directors of
WebTone. In June 1999, S1 and WebTone entered into a Letter of Understanding
pursuant to which S1 received approximately 3% of WebTone's fully diluted
outstanding shares in exchange for cancelling $173,000 of outstanding
receivables and in recognition of S1's interest in the development of WebTone.
As contemplated by the Letter of Understanding, in November 1999 WebTone entered
into a License and Reseller Agreement with S1. Under that Reseller Agreement,
WebTone licensed to S1 certain WebTone software for internal development
purposes, data processing purposes and to resell to financial institution
customers. Under the Reseller Agreement, S1 can elect to receive payments of
fees due in cash or in WebTone stock valued at $2.00 per share in 1999 and at
fair market value, as determined by WebTone's Board, thereafter. There has been
no activity to date under the Reseller Agreement. WebTone paid S1 $47,000 in
1999 for certain administrative and technical services.

In February 1999, S1 and Andersen Consulting LLP entered into a strategic
partnership. S1 issued a warrant to purchase 200,000 shares of S1 common stock
to Andersen Consulting in February. The number of shares represented by the
warrant is adjusted to reflect the May 1999 two-for-one split of S1's common
stock. In April 1999, S1 issued 72,800 shares of S1 common stock to an affiliate
of Andersen Consulting. In 1999, S1 and Andersen Consulting paid each other for
work done on contracts where the other entity was the primary contractor. S1
paid Andersen Consulting a total of $10.0 million for such work and Andersen
Consulting paid S1 a total of $627,000. Jackson L. Wilson, Jr., a director of
S1, is a general partner of Andersen Consulting. At December 31, 1999, the
accounts receivable due from Andersen was $270,000.
