<PAGE>
 
For some financial institutions, the Antares 2000 trading system may serve as a

Asset/Liability Management
PTS 2000

PTS 2000 provides an economic model of insurance assets and liabilities,
generating option-adjusted cash flows to reflect the complex sets of options and
covenants frequently encountered in insurance contracts or comparable
agreements. PTS 2000 includes the following features:

Large-Scale Corporate Simulation Models. The Company and certain significant
----------------------------------------                                    
clients have implemented a number of complex models of whole-company financial
performance. Unlike simpler systems, PTS 2000 maintains an internal architecture
patterned after the structure of insurance companies themselves, making full-
scale corporate models practical. Such corporate models are used to facilitate
capital structure decisions, revealing and measuring overall financial
performance, and guiding overall risk management practice.

Option Pricing. The PTS 2000 option-pricing model provides option-adjusted
---------------                                                           
valuation of assets and liabilities under a consistent conceptual framework. The
PTS 2000 option pricing model explicitly considers interest-sensitive embedded
options, providing valid interest rate risk analysis, using price behavior
curves that graphically depict asset/liability performance over shifts in the
interest rate term structure.

Macro Pricing.  The Company's proprietary Macro-Pricing algorithm recognizes the
--------------                                                                  
complex relationships within contemporary financial intermediaries and provides
a matrix of possible product and production quota options in conformity with the
profit expectations of the client.


Dynamic Financial Analysis
Finesse 2000

The Company's Finesse 2000 system is a Dynamic Financial Analysis tool designed
and developed in cooperation with Ernst & Young LLP, to model operating results,
gauge the effects of reinsurance and validate pricing, value business
transactions such as mergers and acquisitions, measure the impact of new
products, predict cash flows, analyze the impact of investment decisions, and
improve strategic planning. Finesse 2000 generates iterative, computer-simulated
scenarios in response to events that may have an impact on a client's business.
The results of this iterative process are stored in Finesse 2000's "virtual
general ledger," which mimics the financial accounting that would occur if these
scenarios were to occur. All simulated results are recorded and can be easily
viewed on Finesse 2000's "graphical palette," an on-line facility that visually
depicts the likely occurrence of one or more specific events.


Loan Management
LMS 2000

LMS 2000 enables mortgage professionals to process, analyze and report on a
comprehensive basis, information regarding their mortgage loan portfolios. LMS
2000 is a 32-bit, multi-user, integrated solution operating on a client/server
platform, which eliminates the need for separate, independent systems within the
mortgage loan area. LMS 2000, which can be integrated with data stored in the
Company's CAMRA 2000 and PTS 2000 products, provides the following features:

Application and Commitment Processing. LMS 2000 supports the processing of
--------------------------------------                                    
commercial and residential mortgage loans, providing on-line access to critical
evaluative information, including credit history, appraisals, ratio, broker
information, duration, convexity, average life and discounted cash flow
valuation, permitting loan recommendations to be generated quickly,
consistently, and easily.

Accounting and Servicing Support. LMS 2000 supports accurate and consistent
---------------------------------                                          
servicing of loans, including general ledger entries at the sub-portfolio level,
with a direct interface to the corporate general ledger.  LMS 2000 also

Real Estate Equity Management

Real Estate Management System (REMS) is an integrated suite of software
applications, including Real Estate Financials, Property Accounting, Financial
Modeling, Registry, Property Operations, and Leasing Management -  designed
around the functional areas of real estate organizations to provide a single
solution for managing information.

SKYLINE for Windows is property management software that manages all aspects of
office/industrial, residential, and retail properties, even those which are
decentralized geographically. SKYLINE also features detailed, informative
reports. SKYLINE Enterprise is a similar system, but capable of handling larger
amounts of data required for the management of a large amount of property
holdings.

PRO-JECT for Windows is property valuation software that calculates the value of
any combination of office, industrial, retail, apartment and mixed-use property
types. It can perform sophisticated sensitivity analysis on property
assumptions, and produce detailed reports such as present value and consolidated
cash flow reports.


Consulting Services and Outsourcing Services
Consulting Services

Building upon the capability and flexibility of its software products, the
Company offers a range of professional services to assist clients in
implementing the Company's software products and meeting their portfolio
management needs. To facilitate successful product implementation, the Company's
consultants assist clients with initial installation of a system, conversion of
the client's historical data, and ongoing training and support. The Company's
team works closely with the client to ensure smooth transition and operation of
the Company's systems. The Company believes its commitment of dedicated
professionals to facilitate the transition process strengthens its relationship
with the client, provides the Company with valuable information regarding client
requirements and offers the opportunity for sales of additional Company products
and services to the client. The Company's consultants have a broad range of
experience in the financial services industry and include certified public
accountants, chartered financial analysts, mathematicians and professionals from
the asset management, real estate, investment, insurance and banking industries.
In addition, the Company offers actuarial consulting services to its insurance
company and other financial institution clients. The Company believes its
commitment to professional services facilitates the adoption of the Company's
software products across its target markets.


SS&C Direct

For those clients wishing to outsource certain portfolio accounting, reporting
and analysis functions, the Company also provides comprehensive outsourcing
services through its SS&C Direct operating unit. The Company's consultants
initially work with a client to research and evaluate data sources, implement
custodian and pricing interfaces and determine reporting requirements and
timing. The Company provides its clients with accurate, processed data on a
timely basis, enabling investment professionals to spend their time analyzing
data and making investment decisions rather than managing the back-office
investment operations. The features of the Company's outsourcing services
include: (i) customized access rights to provide on-line access on a per-client
basis; (ii) regular holdings reports, also available on-line, and complete
regulatory support; (iii) disk mirroring, daily back-up of the system and other
data protection measures; or; and (iv) disaster recovery hot site services.

Product Support

The Company believes its high level of service and support is critical to its
success, and an important competitive advantage. Further, the Company believes a
close and active service and support relationship is important to client
satisfaction, and provides the Company with important information regarding
evolving client requirements. The Company provides each of its significant
clients with a dedicated client support representative whose primary
responsibility is to resolve questions and concerns and act as a liaison between
the client and the Company. In addition, the Company provides direct telephone
support during extended business hours. Additional hours are available during
peak periods, and the Company uses the Internet, electronic bulletin boards and
other forms of electronic data distribution that provide clients with the latest
information regarding its products. The Company also provides periodic
maintenance releases of licensed software to its clients, including regulatory
updates, generally during the fourth quarter, to enable them to meet industry
reporting obligations and other processing requirements as they evolve. The
Company's service and support activities are supplemented by comprehensive
training, including introductory training courses for new users.


Clients

The Company's clients include a wide range of financial institutions and other
organizations that require a full range of information management and analysis,
accounting, actuarial, reporting, and compliance software on a timely and
flexible basis, and include asset managers, insurance companies, banks,
corporate treasuries, hedge funds, family offices, real estate asset managers,
and government agencies. The Company provides products and services to more than
5,500 organizations worldwide.


Sales and Marketing

The Company believes a direct sales organization is essential to the successful
implementation of its business strategy, given the complexity and importance of
the operations and information the Company's products are designed to manage,
and the extensive regulatory and reporting requirements of its clients. The
Company's dedicated direct sales and support staff, which is supplemented by
extensive ongoing product and sales training, is organized by business unit and
situated in the Company's various sales offices. The Company also uses
telemarketing to support sales of its real estate equity products.

The Company's marketing personnel are responsible for evaluating and developing
market opportunities and providing sales support. The Company's marketing
activities include generation of client leads, targeted direct mail campaigns,
seminars, advertising, trade shows, conferences and public relations efforts.
The marketing department also supports the sales force with appropriate
documentation or electronic materials for use during the sales process.


Product Development; Research and Development; Backlog

The Company believes it must introduce new products and features into the market
on a regular basis to maintain its competitive advantage. To meet these goals,
the Company uses multidisciplinary teams of highly trained finance, accounting,
mathematical, actuarial, software and investment personnel, and has invested
heavily in developing a comprehensive product analysis process to meet rigorous
requirements for product functionality and quality across its target markets.

The Company's research and development engineers work closely with the Company's
marketing and support personnel to assure product evolution reflects
developments in the marketplace and trends in client requirements. Historically,
the Company has issued a major functional release of its core products during
the third quarter of each fiscal year, including functional enhancements, as
well as an annual fourth quarter release to reflect evolving regulatory changes
in time to meet clients' year-end reporting requirements.

Although the Company historically has met its scheduled dates for product
releases and enhancements, software development is characterized by
unanticipated delays, and there can be no assurance that the Company will be
able to maintain future scheduled release dates as planned. Further, there can
be no assurance that the Company's new product releases and product enhancements
will adequately address the needs of the marketplace or will not contain "bugs"
which could cause delays in product introduction or shipments or, if discovered
in the future, require modification of the Company's products.

                                       8
<PAGE>
 
As of December 31, 1998, the Company's research and development staff consisted
of 123 employees. The Company's total expenses for research and development,
excluding purchased in-process research and development, for the years ended
December 31, 1996, 1997 and 1998 were $8.4 million, $10.2 million and $17.4
million, respectively.


Backlog is not a significant factor in the Company's business.

Competition

The market for financial services software is competitive, rapidly evolving, and
highly sensitive to new product introductions and marketing efforts by industry
participants. The market is also highly fragmented and served by numerous firms,
many of which serve only their respective local markets or specific customer
types, and much of the Company's competition stems from information systems or
timesharing services developed and serviced internally by the MIS departments of
financial services firms. The Company currently faces direct competition in
various segments of the financial services industry from Thomson Financial,
SunGard Data Systems, Inc., Princeton Financial Systems (a subsidiary of State
Street Bank and Trust Company), Financial Models Company Inc., DST Systems,
Inc., and Advent Software, Inc. The Company believes none of its competitors
currently competes against it in all of its target industry segments, although
there can be no assurance that one or more may not compete against the Company
in the future in additional industry segments. Many of the Company's current and
potential future competitors have significantly greater financial, technical,
and marketing resources, generate higher revenues, and have greater name
recognition than does the Company. There can be no assurance that the Company's
current or potential competitors will not develop products comparable or
superior to those developed by the Company or adapt more quickly than the
Company to new technologies, evolving industry trends or changing client
requirements. It is also possible that alliances among competitors may emerge
and rapidly acquire significant market share. Increased competition may result
in price reductions, reduced gross margins and loss of market share, any of
which would materially adversely affect the Company's business, financial
condition, and results of operations.

The Company believes the principal competitive factors in its industry include
product performance and functionality, ease of use, scalability, ability to
integrate external data sources and processing systems, product and company
reputation, client service and support, and price. Although the Company believes
it currently competes effectively with respect to such factors, there can be no
assurance that the Company will be able to maintain its competitive position
against current and potential competitors.


Proprietary Rights

The Company primarily relies on a combination of copyright, trademark, and trade
secret laws and license agreements to establish and protect proprietary rights
of its products. The source code for the Company's products is protected as both
a trade secret and an unpublished copyrighted work. In addition, the Company
generally enters into confidentiality and/or license agreements with its
employees, distributors, clients, and potential clients and limits access to,
and distribution of, its software, documentation, and other proprietary
information. Despite these precautions, it may be possible for a third party to
copy or otherwise obtain and use the Company's products or technology without
authorization or to develop similar technology independently. In addition,
effective copyright and trade protection may be unavailable or limited in
certain foreign countries. In January 1996, the Company licensed the use of
certain of its source code to General American Life Insurance Company and
Conning Asset Management Company, affiliates of certain stockholders of the
Company.

Because the software development industry is characterized by rapid
technological change, the Company believes factors such as technological and
creative skills of its personnel, new product developments, frequent product
enhancements, name recognition, and reliable service and support are more
important to establishing and maintaining a leadership position than legal
protections of its technology.


Employees

As of December 31, 1998, the Company had 462 full-time employees, consisting of
123 employees in research and development, 93 employees in consulting and
services, 57 employees in sales and marketing, 58 employees in client support,
45 employees in finance and administration, and 86 employees in the Company's
international operations. None of these employees is covered by any collective
bargaining agreements. The Company believes its relationship with its employees
is good. The future success of the Company will depend upon its ability to
attract and retain qualified personnel. Competition for such personnel is often
intense, and there can be no assurance that the Company will be able to attract
and retain adequate numbers of qualified personnel in the future.

ITEM 2.   PROPERTIES

     The Company leases its corporate offices, consisting of 54,000 square feet
of office space, in Windsor, Connecticut. It relocated from a building it
continues to own in Bloomfield, Connecticut during the second quarter of 1998.
The initial lease term is for ten years and the Company has the right to extend
the lease for one additional term of five years. The lease requires annual
payments of $717,000 for each of the first five years and annual payments of
$757,000 for each of the remaining five years. In support of direct sales and
support operations, the Company utilizes facilities and offices in ten locations
in the United States and Canada and also has offices in London, England;
Amsterdam, Netherlands; and Kuala Lumpur, Malaysia.


ITEM 3.   LEGAL PROCEEDINGS

     On March 18, 1997, Elery G. Montagna and Marjory G. Montagna filed a
purported class action lawsuit in the United States District Court for the
Southern District of New York (the "New York Complaint") against the Company and
certain of its executive officers, as well as against BT Alex. Brown
Incorporated (as successor to Alex. Brown & Sons Incorporated, "Alex. Brown")
and Hambrecht & Quist LLC ("Hambrecht & Quist"), the lead managers of the
Company's initial public offering. On April 8, 1997, Marc A. Feiner filed a
purported class action lawsuit in the United States District Court for the
District of Connecticut (the "Connecticut Complaint") against the Company, its
directors and certain of its executive officers, as well as against Alex. Brown
and Hambrecht & Quist. On July 8, 1997, Marc A. Feiner, Joseph Aogiere, Arthur
S. Davis, Theodore S. Davis, James Gregory, Brian Kreidler, Daniel Kreidler,
Robert Miller, Elery Montagna, Marjory Montagna and Gilda Shapiro Trust filed a
Consolidated Amended Class Action Complaint in the United States District Court
for the District of Connecticut (the "Consolidated Complaint") in which the New
York Complaint and the Connecticut Complaint were consolidated and amended. The
Consolidated Complaint claims that the Prospectus for the Company's initial
public offering allegedly made material misrepresentations in violation of
Sections 11 and 12(2) of the Securities Exchange Act of 1933. The plaintiffs are
seeking an undetermined amount of damages and costs and expenses of the
litigation. The plaintiffs filed a motion to certify a class in this matter on
May 29, 1998. The Company filed its opposition to class certification on
September 25, 1998, and Alex. Brown and Hambrecht & Quist filed a separate
opposition on September 29, 1998. The plaintiffs filed a reply brief on the
class certification issue on October 26, 1998, and the defendants filed surreply
briefs on November 10, 1998. The court has not yet ruled on the motion for class
certification. The matter is now in the discovery phase. The Company believes it
has meritorious defenses to the claims made in the lawsuit and intends to
contest the Consolidated Complaint vigorously. Although the amounts claimed may
be substantial, management cannot predict the ultimate outcome or estimate the
potential loss, if any, related to these claims. Management believes that the
disposition of this matter will not have a material adverse effect on the
Company's consolidated financial position. However, the adverse resolution of
one or more of these claims could materially affect the Company's consolidated
results of operations or liquidity in any one annual or quarterly reporting
period.

     From time to time, the Company is subject to certain legal proceedings and
claims that arise in the normal course of its business.  In the opinion of
management, the Company is not a party to any other litigation that it believes
could have a material effect on the Company or its business.
