OUR COMPANY

     i2 is a leading provider of dynamic and value-chain software solutions that
may be used by enterprises to optimize business processes both internally and
among trading partners. Our solutions are designed to help enterprises improve
efficiencies, collaborate with suppliers and customers, respond to market
demands and engage in dynamic business interactions over the Internet. Our
products consider the conditions of companies to optimize key business
processes -- from product design to customer relationships. Our products are
designed to help customers, partners, suppliers and service providers conduct
business together and offer a technology infrastructure supporting
collaboration, commerce and content. Our product suites include software
solutions for supply chain management, supplier relationship management and
customer relationship management. We also provide content and content management
solutions as well as a platform for integration and administration of private
and public electronic marketplaces. Our product suites may be used by our
customers to align their value chain to serve their customers. We also provide
services such as consulting, training and maintenance in support of these
offerings.

     As part of our strategic plan, we have invested in companies to acquire
software and other products that complement ours. On June 9, 2000, we completed
the acquisition of Aspect Development, Inc. (Aspect), a developer of
collaborative solutions for business-to-business marketplaces. Prior to the
acquisition of Aspect, we acquired SupplyBase, Inc. (SupplyBase), a developer of
interactive database products, services and supply chain management tools on
April 28, 2000. These acquisitions were accounted for using the purchase method
and have enabled us to quickly advance our content market offering.

     On December 27, 2000, we entered into a definitive agreement to acquire
Trade Services Corporation, a leading provider of maintenance, repair and
overhaul (MRO) content and its affiliate ec-Content, Inc., which develops and
manages content for digital marketplaces, e-procurement and supplier
syndication. Pursuant to the amended agreement, we purchased all the outstanding
stock of both companies for approximately $74.1 million, including acquisition
related costs. The total purchase price includes $5.0 million in cash, 800,000
shares of our common stock with a fair market value of $12.4 million, a
convertible promissory note currently valued at $56.1 million and approximately
$0.6 million in acquisition costs. This acquisition closed on March 23, 2001 and
will be accounted for using the purchase method.

     On March 8, 2001, we entered into a definitive agreement to acquire
RightWorks Corporation, a developer of software that is designed to enable
companies to manage procurement across multiple enterprises for both direct and
indirect materials, and support buying models, from negotiated procurements to
auctions. In connection with the acquisition, we will exchange approximately 5.3
million shares of our common stock for all the outstanding stock of RightWorks.
The transaction is expected to close in the third quarter of 2001 and will be
accounted for using the purchase method.

INDUSTRY BACKGROUND

     Today's increasingly competitive business environment has forced many
companies in diverse industries to increase efficiencies while improving
flexibility and responsiveness to changing market conditions. In addition to
facing higher competitive standards with respect to product quality, variety and
price, businesses also recognize the need to shorten lead times, adjust
production for frequent changes in customer requirements and quote more accurate
and reliable delivery dates. Furthermore, a company's trading network may span
multiple continents, requiring suppliers in one part of the world to collaborate
with a plant in another to serve customers in yet a third location. These forces
are prompting companies to collaborate with a broad range of suppliers and
customers to improve efficiencies across multi-enterprise value chains and
marketplaces.

     In the past, companies have sought to address the changing business
environment by investing in enterprise resource planning (ERP) systems and first
generation e-commerce systems; however, these systems do not provide the forward
visibility and high-speed decision-support capabilities required by many
businesses today. To increase competitiveness, many companies are looking for a
comprehensive suite of products that provide tools for improved visibility, fast
and accurate decision-making, and execution across all critical processes.

     The growth of the Internet and the proliferation of software applications,
such as applications for supply chain management, supplier relationship
management, and customer relationship management, are accelerating many
companies' efforts to increase efficiencies by enabling a platform-independent
communications network. This platform independence has prompted demands for a
dynamic, open and integrated environment among customers, suppliers, and
designers. In response to these evolving market forces, many companies have
sought to re-engineer their business processes to reduce manufacturing cycle
times, shift from mass production to order-driven manufacturing, increase the
use of outsourcing and share information more readily with vendors and customers
over the Internet.

THE i2 SOLUTION

     We provide our customers with dynamic software solutions and services
designed to optimize and integrate key business processes including supply chain
management, customer relationship management and

                                        3
<PAGE>   4

supplier relationship management. Our solutions are also capable of web-based,
real-time collaboration and order fulfillment capabilities in both
business-to-business and business-to-consumer exchanges. Customers are using our
solutions to design or re-engineer their business models in pursuit of increased
market share and enhanced competitiveness.

     Our i2 TradeMatrix products are built upon our foundation of advanced
planning, optimization and execution capabilities. Our products can help build
competitive advantage and profitability by combining operational excellence,
customer intimacy and product leadership.

     Our approach to customer relationships is centered on the creation of value
for our customers. As part of this dedication to providing value for our
customers, in 1995, we established a goal of generating more than $50 billion in
total value through growth and savings for our customers by 2005. In 2000, we
increased our goal to provide $75 billion in total value by 2005. We have
reported over $16 billion of value delivered to date toward this goal.

i2 -- A HISTORY OF INNOVATION

     We have offered supply chain management solutions since the company was
founded 13 years ago. Our founders, Sanjiv Sidhu and Ken Sharma, developed a
dynamic solution to optimize the flow of materials within a factory. This
solution, Factory Planner, was our flagship product and it has assisted our
customers in maximizing the profitability of their factories while reducing
their materials and inventory costs.

     We then expanded this solution to the extended supply chain, which includes
multiple factories, distribution centers, warehouses and logistics, and added
solutions for demand planning and fulfillment. We have continued to apply
innovative solutions to the extended supply chain, supplier relationship and
customer relationship processes and functions. To facilitate the design of new
products, we provide customers with solutions that are able to more efficiently
source and procure materials and components from suppliers, contract with
suppliers, and make design decisions knowing how they will affect existing
products and the total product portfolio supply chain. We offer solutions for
managing the order-to-cash cycle in customer relationship management, aimed at
customer concerns regarding product selection, prices, availability of products,
order management and settlement on orders.

     As the business environment evolved, we introduced marketplace services
consisting of a portfolio of shared information services to enable public and
private digital trading communities to optimize both planning and trading
processes. These services are designed to provide enhanced decision making and
transaction execution within business-to-business and business-to-consumer
environments, from collaboration with strategic partners to fulfilling and
tracking multi-vendor orders for customers. Private trading communities address
a known set of participants, such as a company and its customers, suppliers or
service providers. Public trading communities offer open participation for a
target industry.

PRODUCTS

     Our i2 TradeMatrix products operate as flexible, integrated solutions and
are available in single and multi-site configurations, with various extensions.
Our solutions are designed to assist our customers in improving current business
processes, return on assets, profitability and customer service levels. As a
result of these and other advantages, our solutions are designed to help
customers increase market share, enhance their competitive advantage and deliver
on their promises to their customers. Our primary products are contained in the
following groups: i2 Supply Chain Management, i2 Customer Relationship
Management, i2 Supplier Relationship Management, i2 Content, i2 TradeMatrix
Platform, and TradeMatrix Network.

     i2 Supply Chain Management(TM) (SCM).  The i2 SCM suite helps businesses
coordinate the movement of goods and materials through the supply chain, to
product delivery and to the customer. Using the i2 SCM suite, a business can
estimate future demand for its products to enable planners to more accurately
estimate future supply needs. As a result, businesses can make better decisions
about how much of what products to make, when, and what parts to have in
inventory to make those products. The i2 SCM suite also extends to the planning
of procurement, production, logistics and services. We also recently announced
i2 TradeMatrix

                                        4

Pronto(TM) as a part of our SCM product group. Pronto is a supplier enablement
solution for mid-market companies that allows suppliers to participate in the
extended supply chain with their customers. Pronto is designed to enable
suppliers to respond to their customers with reliable and profitable supply
commitments.

     i2 Customer Relationship Management(TM)(CRM).  The foundation of the i2 CRM
suite drives the order management and fulfillment processes of managing customer
relationships, providing visibility into inventory so a company can make
accurate promises and deliver in the fastest way at the lowest cost. From this
base, the i2 CRM suite provides solutions for marketing, sales and service,
including such functionality as campaign management, opportunity qualification
and management, product configuration, pricing, order management, service asset
management, service scheduling and dispatch.

     i2 Supplier Relationship Management(TM) (SRM).  The i2 SRM suite is an
integrated suite of business-to-business design, sourcing and procurement
capabilities that enables companies and their suppliers to collaboratively
create and manufacture better products faster, at lower cost. The strategic
solutions in the i2 SRM suite provide decision-support and optimization tools
that help companies improve decision-making on supplies and the parts to use in
products. During product development, the i2 SRM suite optimizes designs by
considering sourcing and supply chain constraints, as well as allowing design
collaboration when outsourcing manufacturing or custom parts. During
procurement, the i2 SRM suite enables companies to define sourcing strategy to
reduce supply risks and costs, negotiate terms and streamline the requisitioning
and buying of both direct and indirect materials.

     i2 Content.  Content is the knowledge behind e-business decisions and the
information about items and suppliers that can be used to describe, search,
compare, buy or select an item. Without content, e-commerce is impossible. The
i2 Content solution consists of content management software, content services
and reference content. Our content management software provides publication,
subscription, management and syndication functionality for marketplaces and
enables the searching of multiple marketplaces, the identification of parts or
services that match both technical and price criteria and the delivery of
business-to-business content services via the Internet. Additionally, our
content management software provides a standards-based method for content
exchange and collaboration among trading partners and marketplaces.

     Content services provided with i2 Content include legacy data conversion
services and custom content creation-capabilities that enable enterprises and
marketplaces to access needed part, component and supplier data.

     Our reference content contains over 20 million part, component, and
item-specific records from thousands of suppliers worldwide and provides
detailed technical and pricing information about the available products and the
suppliers that are connected to the marketplace. Our reference content also
provides technical information to select parts -- searchable by form, fit, or
function.

     i2 TradeMatrix Platform.(TM)  The i2 TradeMatrix Platform enables companies
to design, deploy, operate and monitor e-marketplaces with security, reliability
and scalability. It is a flexible, open, standards-compliant, integrated system
that provides the infrastructure, administration services and intelligence for
marketplace owners. The i2 TradeMatrix Platform supports e-business interactions
from auctions, to collaboration, to inter-enterprise planning; provides a
multi-enterprise supply chain model to enable collaborative decision-support
across multiple business partners; provides open, standard messaging; and
leverages existing information technology infrastructures.

     TradeMatrix Network.(TM)  TradeMatrix Network is a web of private and
public marketplaces whereby participants can gain access to an expanded
population of business partners and customers as well as an expanded set of
e-business services. TradeMatrix Network is intended to address the
e-marketplace and partner connectivity challenges faced by businesses.
TradeMatrix Network extends the i2 SRM, SCM and CRM solutions to gain access to
real-time information from trading partners and marketplaces.

PRODUCT DEVELOPMENT

     We originally introduced our RHYTHM software in 1992 and subsequently have
added many new products and product enhancements. We rebranded RHYTHM solutions
as i2 TradeMatrix solutions in 2000,

                                        5
<PAGE>   6

unifying it within the i2 TradeMatrix framework. We have adopted a strategy of
periodically reinventing our products to meet our customers' needs and we strive
to ensure that each new generation of our products is compatible with previous
releases. We focus our ongoing product development efforts on broadening or
deepening the functionality of our core products and services to address new
industries, marketplaces and geographic markets. These services and solutions
are evolving and have been developed using an architecture for e-business that
is (1) modular, so components may be easily substituted; (2) flexible, to
quickly respond to changing business conditions; (3) open, to support multiple
protocols; and (4) scalable, to handle the large volumes of queries and
transactions that are typical in a business environment.

     Our internal development staff has developed our products through project
teams focused on independent components of the software under development. We
maintain product release planning procedures to ensure integration, testing and
version control among the different project development teams. We maintain
development centers in various cities in the U.S. and in Canada, Finland, India
and the United Kingdom.

     Research and development expenses totaled $217.9 million in 2000, $132.3
million in 1999 and $94.2 million in 1998. While we have continued to focus on
development of new and enhanced products, research and development expenses have
declined as a percentage of revenues in recent periods. Research and development
expenses were 19.3% of total revenues in 2000, down from 23.2% in 1999 and 25.5%
in 1998.

CUSTOMER SERVICE AND SUPPORT

     We believe that providing high levels of customer service and technical
support are necessary to achieve customer satisfaction and continued license
sales and revenue growth. We have expanded our service and support centers
geographically and now have support centers in the U.S. and in Australia,
Belgium, Brazil, Canada, Denmark, France, Germany, India, Japan, Mexico,
Singapore, South Africa, Taiwan and the United Kingdom. Accordingly, we are
committed to continue recruiting and maintaining a high-quality technical
support team. Our customer service and support activities consist of the
following:

     Consulting.  We offer our customers on-site consulting services aimed at
assisting in the implementation of our solutions and services and integration
with the customers' existing systems. These consulting services are concentrated
on making implementation cost-effective for customers by enabling them to
independently perform as many of the integration tasks as possible. We also
leverage the use of global third-party consulting firms to more rapidly
penetrate our target markets.

     Training.  We offer education and training programs for our customers and
our third-party implementation providers. Classes are offered at our offices and
at customer locations. These classes focus on the fundamental principles of our
software products as well as implementation and use.

     Maintenance and Product Updates.  We provide ongoing product support
services for our solution suites. Maintenance contracts are typically sold to
customers at the time of the initial license and may be renewed for additional
periods. Our maintenance agreements with our customers provide product updates
and enhancements to the products purchased by the customer. Ongoing support and
maintenance services are available on a seven-day week, 24-hour day basis, if
desired.

     Hosting Services.  Customers can choose to have certain i2 software hosted
through a third party, including our current certified hosting providers, IBM
and Sabre. We offer a variety of services to our customers using third-party
hosting providers, including the initial configuration, upgrades and managed
services for the hosted environment.

SALES AND MARKETING

     We sell our software and services through our direct sales organization
augmented by other sales channels, including e-business providers and systems
consulting and integration firms. Our direct sales organization consists of
sales representatives and pre-sales consultants supported by personnel with
industry experience in aerospace and defense, automotive, chemicals, durable and
non-durable consumer goods, high-tech hardware and electronics, industrial
equipment, logistics, metals, pulp and paper, pharmaceuticals, retail,
semiconductors, textiles and apparel and telecommunications.

                                        6
<PAGE>   7

     We currently have joint marketing agreements with over 60 software vendors
and e-business providers, including Broadvision, IBM and Siebel, and nearly 80
systems consulting and integration firms, including Accenture, A. T. Kearney,
Cap Gemini Ernst & Young, EDS, Deloitte & Touche, IBM Global Services and
PricewaterhouseCoopers. These joint marketing agreements generally provide the
vendors with non-exclusive rights to market our products and access to our
marketing materials and product training. By using these indirect sales
channels, we seek to capitalize on the installed base of other e-business
providers and obtain favorable product recommendations from systems consulting
and integration firms, thereby increasing the market coverage of our products.
We have also negotiated contracts to receive a specified fee from other software
providers when these companies offer their products to customers through our i2
TradeMatrix Platform.

INTERNATIONAL OPERATIONS

     We have international offices in Australia, Belgium, Brazil, Canada, China,
Denmark, Finland, France, Germany, India, Italy, Japan, Korea, Malaysia, Mexico,
Netherlands, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan and the
United Kingdom. Total assets related to our international operations accounted
for 3.8% of our total consolidated assets (20.2% of total consolidated assets
excluding intangible assets) as of December 31, 2000. In 2000, international
revenues accounted for 34.9% of total revenues.

COMPETITION

     The markets in which we operate are highly competitive. Our competitors are
diverse and offer a variety of solutions targeting various segments of the
extended supply chain as well as the enterprise as a whole. Some competitors
compete with suites of applications designed to offer out-of-the-box
integration, while most offer point solutions designed specifically to target
particular functions or industries. We attempt to bring together best-of-breed
applications in an integrated environment to capture the advantages of both
approaches, and to offer our customers a one-stop shop for critical e-business
solutions. More specifically, we compete with:

     - Large ERP software vendors, including Oracle and SAP, who have added or
       are attempting to add capabilities for supply chain planning or
       business-to-business collaboration to their transaction system products.

     - Companies such as Adexa, Manugistics and others that compete principally
       with our supply chain management applications.

     - Companies such as Agile, Commerce One and others that compete principally
       with our supplier relationship management applications.

     - Companies such as Trilogy and others that compete principally with our
       customer relationship management applications.

     - Companies such as RTI, Saqqara and others that compete principally with
       our content and content management applications.

     - Other vendors who establish electronic marketplaces and indirect
       procurement capabilities that may compete now or in the future with
       marketplaces created or powered by us.

     - Other business application software vendors that may offer or partner
       with independent developers of advanced planning and scheduling software.

     - Internal development efforts by corporate information technology
       departments.

PROPRIETARY RIGHTS AND LICENSES

     We regard our trademarks, copyrights, trade secrets, technology and other
proprietary rights as critical to our business. To protect our proprietary
rights, we primarily rely on a combination of copyright, trademark and trade
secret laws, confidentiality procedures, license agreements and contractual
provisions. We license our software products in object code (machine-readable)
format to customers under license agreements and we do

                                        7
<PAGE>   8

not sell or otherwise transfer title of our software products to our customers.
Our non-exclusive license agreements generally allow the use of our software
products solely by the customer for specified purposes without the right to
sublicense or transfer our software products.

     Trademarks are important to our business as we use them in our marketing
and promotional activities as well as with the delivery of our software
products. Our registered trademarks include i2, i2 Technologies and Design,
RHYTHM and PLANET. Other trademarks of i2 include TRADEMATRIX, i2 TRADEMATRIX,
IN2ACTION, TRADEMATRIX NETWORK, INFINITE CONTENT and DESIGN and POWERING THE
BOTTOM LINE.

     We hold a number of U.S. patents that predominantly relate to planning
systems and interactive report generation. These patents expire at various times
through 2018. We also depend on trade secrets and proprietary know-how for
certain unpatented aspects of our business. To protect our proprietary
information, we enter into confidentiality agreements with our employees,
consultants and licensees, and generally control access to and distribution of
our proprietary information. We resell some software that we license from third
parties and incorporate in, or sell in conjunction with, our products.

EMPLOYEES

     As of February 28, 2001, we had approximately 6,000 full-time employees,
including approximately 1,950 primarily engaged in research and development
activities and approximately 1,700 engaged in sales and marketing activities.
Our future success depends in significant part upon the continued service of our
key technical and senior management personnel and our ability to attract and
retain highly qualified technical and managerial personnel. None of our
employees are represented by collective bargaining agreements and we have never
experienced a work stoppage. We believe employee relations are very good.

ITEM 2. PROPERTIES

     Our primary offices are located in Dallas, Texas and are held under lease
contracts that expire at various dates through 2011. These facilities house our
executive and primary administrative offices as well as sales, marketing,
research and development and consulting personnel. We also lease space for our
other offices in the U.S., Australia, Belgium, Brazil, Canada, China, Denmark,
Finland, France, Germany, India, Italy, Japan, Korea, Malaysia, Mexico,
Netherlands, Singapore, Spain, South Africa, Sweden, Switzerland, Taiwan and the
United Kingdom primarily to provide sales, customer support, consulting services
and research and development activities.

     We consider our properties to be suitable and adequate for our present
needs. We maintain options to lease additional space in areas near our current
facilities to the extent necessary based on our current and expected future
level of facility utilization.

ITEM 3. LEGAL PROCEEDINGS

     On October 10, 2000, we settled a lawsuit filed by a former employee
alleging his right to exercise stock options granted to him in 1996 while he was
employed by us, prior to the initial public offering of our stock. The
settlement resulted in the recognition of a $22.4 million non-cash, pre-tax
charge during the third quarter of 2000. In a separate matter, an employee of a
company we acquired in 1998 is currently disputing the cancellation of stock
options received at the time of the acquisition. Vesting of these options was
dependent upon continued employment; however, the employment was terminated in
2000. We maintain the former employee was not entitled to unvested stock
options.

     Since March 2, 2001, several class action lawsuits have been filed in the
United States District Court, Northern District of Texas, Dallas Division,
alleging that we and certain of our officers have violated federal securities
laws. In substance, all of the complaints allege that we issued a series of
false and misleading statements which failed to disclose, among other things,
that we were experiencing software implementation difficulties with our customer
Nike, Inc. and that these problems were material, severe and damaging our
relationship with Nike. The plaintiffs in the actions purport to represent
persons who purchased our stock

                                        8
<PAGE>   9

during various periods ranging from October 18, 2000 to February 26, 2001. As
these suits have just been filed, we have not had the opportunity to adequately
review the claims or respond. Although the ultimate outcome and liability, if
any, cannot be determined, we believe the facts in these class actions do not
support the plaintiffs' claims and we and our officers and directors have
meritorious defenses.

     We are subject to various other claims and legal actions arising in the
ordinary course of business. In the opinion of management, after consultation
with legal counsel, the ultimate disposition of these matters is not expected to
have a material effect on our business, financial condition or results of
operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     At a special meeting of stockholders held on November 28, 2000, our
stockholders voted on a proposed amendment to our Restated Certificate of
Incorporation to increase the number of authorized shares of our common stock
from 0.5 billion to 2.0 billion. This amendment was approved.

     As of March 26, 2001, there were 410,735,877 shares of our common stock
outstanding held by 1,011 holders of record.

     We have never declared or paid cash dividends on our capital stock. We
currently intend to retain any earnings for use in our business and do not
anticipate paying any cash dividends in the foreseeable future. Future
dividends, if any, will be determined by our Board of Directors.

     On March 9, 2001, we announced a voluntary stock option exchange program
for the benefit of our employees. Under the program, our employees have the
option to cancel certain outstanding stock options previously granted to them
for new stock options to be granted no earlier than October 8, 2001. The new
options will be granted with a strike price to be set at the fair market value
of our stock at the date of grant. Employees will receive 1.1 new stock options
for each stock option cancelled. The exchange program has been organized to
comply with applicable accounting standards and, accordingly, no compensation
charges related
                                        9
<PAGE>   10

to this program will result. Members of our Board of Directors, executive
officers, and certain members of the senior management team are not eligible to
participate in this program.

     During the fourth quarter of 2000, we issued an aggregate of 842,536 shares
of our common stock to employees pursuant to exercises of stock options that
were granted prior to April 26, 1996 with exercise prices ranging from $0.0022
to $1.51 per share. These issuances were deemed exempt from registration under
Section 5 of the Securities Act of 1933 in reliance upon Rule 701 thereunder.
The recipients of securities in each such transaction represented their
intentions to acquire the securities for investment only and not with a view to,
or for sale in connection with, any distribution thereof and appropriate legends
were affixed to the share certificates issued in each such transaction.

     On December 10, 1999, we issued an aggregate principal amount of $350.0
million of our 5.25% convertible subordinated notes due 2006. The notes are
convertible, at the option of the holder, into shares of our common stock at a
conversion price of $38.00 per share at any time prior to maturity. On or after
December 20, 2002, we have the option to redeem, in cash, all or a portion of
the notes that have not been previously converted. As of December 31, 2000, none
of the notes have been converted to common stock.

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

FORWARD-LOOKING STATEMENTS

     This report contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. All statements other than historical or current facts,
including, without limitation, statements about our business, financial
condition, business strategy, plans and objectives of management and our future
prospects, are forward-looking statements. Although we believe that the
expectations reflected in such forward-looking statements are reasonable, such
forward-looking statements are subject to risks and uncertainties that could
cause actual results to differ materially from these expectations. Such risks
and uncertainties include, without limitation, the following:

     - Our financial results may vary significantly from quarter to quarter or
       we may fail to meet expectations, which would negatively impact the price
       of our stock.

     - We anticipate seasonal fluctuations in revenues, which may cause
       volatility in our stock price.

     - Historically, a small number of individual license sales have been
       significant in each quarterly period. Therefore, our operating results
       for a given period could suffer serious harm if we fail to close one or
       more large sales expected for that period.

     - We may not remain competitive and increased competition could seriously
       harm our business.

     - Any decrease in demand for our products and services could significantly
       reduce our revenues.

     - Other risks indicated below under the caption "Factors that May Affect
       Future Results" and in our other filings with the Securities and Exchange
       Commission.

     These risks and uncertainties are beyond our control and, in many cases, we
cannot predict the risks and uncertainties that could cause our actual results
to differ materially from those indicated by the forward-looking statements.
When used in this document, the words "believes," "plans," "expects,"
"anticipates," "intends," "continue," "may," "will," "should" or the negative of
such terms and similar expressions as they relate to us or our management are
intended to identify forward-looking statements.

     References in this report to the terms "optimal" and "optimized" and words
to that effect are not necessarily intended to connote the mathematically
optimal solution, but may connote near-optimal solutions, which reflect
practical considerations such as customer requirements as to response time,
precision of the results and other commercial factors.

REVENUES

     Revenues consist of software license revenues, service revenues, and
maintenance revenues, and are recognized in accordance with Statement of
Position (SOP) 97-2, "Software Revenue Recognition," as modified by SOP 98-9,
"Modification of SOP 97-2, Software Revenue Recognition with Respect to Certain
Transactions," and SEC Staff Accounting Bulletin (SAB) 101, "Revenue
Recognition."

     Software license revenues are recognized upon shipment, provided fees are
fixed and determinable and collection is probable. Revenue for agreements that
include one or more elements to be delivered at a future date is recognized
using the residual method. Under the residual method, the fair value of the
undelivered elements is deferred, and the remaining portion of the agreement fee
is recognized as revenue. If fair values have not been established for certain
undelivered elements, revenue is deferred until those elements have been
delivered, or their fair values have been determined. Agreements that include a
right to unspecified future products are recognized ratably over the term of the
agreement. License fees from reseller agreements are generally based on the
sublicenses granted by the reseller and recognized when the license is sold to
the end customer. Licenses to our content databases are recognized over the
terms of the agreements. Fees from licenses sold together with services are
generally recognized upon shipment, provided fees are fixed and determinable,
collection is probable, payment of the license fee is not dependent upon the
performance of the consulting services and the consulting services are not
essential to the functionality of the licensed software.

                                        14
<PAGE>   15

     Service revenues are primarily derived from fees for implementation,
consulting and training services and are generally recognized under service
agreements in connection with initial license sales and as the services are
performed.

     Maintenance revenues are derived from technical support and software
updates provided to customers. Maintenance revenue is recognized ratably over
the term of the maintenance agreement.

     Payments received in advance of revenue recognized are classified as
deferred revenue in the Consolidated Balance Sheets.

     Total revenues increased 97.2% in 2000 and 54.7% in 1999. These increases
resulted from increased demand for our products and services, the expansion of
our product offerings, increased sales activities resulting from additional
sales representatives and additional revenues generated by acquired businesses.
We derived substantially all of our revenues from licenses associated with our
software products and content databases and related services and maintenance.

     Software Licenses.  Software license revenues constituted 63.0% of total
revenues in 2000, 61.7% in 1999 and 63.5% in 1998. Software license revenues
increased $356.6 million, or 101.1%, in 2000 and $118.3 million, or 50.5%, in
1999. The increases in software license revenues for all periods were due to:

     - Increased demand for our products and services.

     - Expansion of product offerings.

     - Increased sales activities resulting from increases in direct sales
       representatives and strategic alliances with industry partners.

     - Increased customer awareness and interest in our product offerings.

     As a result of the above items, the number of recognized software license
transactions increased to 392 transactions in 2000 from 252 transactions in 1999
and 216 transactions in 1998, representing increases of 55.6% and 16.7%. The
average size of individual license transactions increased to $1.8 million in
2000 from $1.4 million in 1999 and $1.1 million in 1998, representing increases
of 29.3% and 28.9%. Additionally, the number of individual software license
transactions in excess of $1 million increased to 150 transactions in 2000 from
66 transactions in 1999 and 55 transactions in 1998, representing increases of
127.3% and 20.0%. Our direct sales channel is responsible for most of our
license revenue.

     Although we believe direct sales will continue to account for most of our
software license revenues for the foreseeable future, our strategy is to
continue to increase the level of indirect sales activities. We expect sales of
our software products through, or in conjunction with, sales alliances,
distributors, resellers and other indirect channels to increase as a percentage
of software license revenues; however, there can be no assurance that our
efforts to expand indirect sales will be successful or will continue in the
future.

     Services.  Service revenues constituted 24.0% of total revenues in 2000,
25.9% in 1999 and 24.8% in 1998. Service revenues as a percentage of total
revenues have fluctuated, and are expected to continue to fluctuate on a
year-to-year basis, as revenues from the implementation of software are not
generally recognized in the same period as the related license revenues. As
large licenses or a significant number of smaller licenses are sold near the end
of a given period, the relative proportion of license revenues to total revenues
will increase compared to service revenues.

     Service revenues increased $123.1 million, or 83.2%, in 2000 and $56.2
million, or 61.2%, in 1999. The increases in service revenues were due to an
increase in the number of solutions sold and resulting demand for consulting and
implementation services. The increases were also due to expanded use of
third-party consultants as subcontractors to provide implementation services to
our customers. This has allowed us to increase our penetration into various
international and targeted vertical markets.

     Maintenance.  Maintenance revenues increased to 13.0% of total revenues in
2000, from 12.4% in 1999 and 11.7% in 1998. Maintenance revenues increased $75.5
million, or 106.9%, in 2000 and $27.5 million, or 63.8%, in 1999. In 2000, we
began offering new tiered levels of maintenance with proportionately higher fees

                                        15
<PAGE>   16

for higher levels of service. The increases in maintenance revenues were also
due to continued increases in software license sales and renewals of maintenance
agreements from prior license sales.

     International Revenues.  Our international revenues are primarily generated
from customers located in Europe, Asia, Canada and Latin America. International
revenues totaled $393.0 million, or 34.9% of total revenues, in 2000; increasing
from $181.2 million, or 31.7% of total revenues, in 1999; and $73.2 million, or
19.8% of total revenues, in 1998. The increase in international revenues is
consistent with our efforts to expand our international presence and sales
efforts. We believe continued growth and profitability will require further
expansion in international markets. We have expended and will continue to expend
substantial resources to expand our international operations.

COSTS AND EXPENSES

     Cost of Software Licenses.  Cost of software licenses consists of:

     - Commissions paid to third parties in connection with joint marketing and
       other related agreements.

     - Royalty fees associated with third-party software.

     - Costs related to user documentation.

     - Costs related to reproduction and delivery of software.

     Cost of software licenses as a percentage of related revenue was 7.5% in
2000, 5.1% in 1999 and 3.4% in 1998. Cost of software license increased $35.4
million, or 196.6%, in 2000 and $10.0 million, or 125.7%, in 1999. The increases
in cost of software licenses, both as a percentage of software license revenue
and in dollar amount, are due to increases in commissions paid to third parties
in connection with joint marketing efforts and other sales assistance, and
increases in the amount of royalty fees associated with third-party software.

     Amortization of Acquired Technology.  In connection with our acquisitions
in 2000, we acquired developed technology that we offer as a part of our
integrated solutions. Amortization of capitalized acquired technology totaled
$29.1 million in 2000. In accordance with SFAS No. 86, "Accounting for Computer
Software to Be Sold, Leased, or Otherwise Marketed," the amortization expense is
included as a part of our cost of revenues because it relates to software
products that are marketed to others.

     Cost of Services and Maintenance.  Cost of services and maintenance
includes costs associated with the implementation of software solutions and
consulting and training services. Cost of services and maintenance also includes
the cost of providing software maintenance to customers such as telephone
support and packaging and shipping costs related to new releases of software and
updated user documentation. Cost of services and maintenance as a percentage of
related revenues was 56.1% in 2000, 57.6% in 1999 and 57.4% in 1998. The
decrease in cost of services and maintenance as a percentage of related revenues
over the comparable periods resulted from efficiencies developed in project
management and other cost saving measures.

     The total cost of services and maintenance increased $108.3 million, or
86.0%, in 2000 and $48.5 million, or 62.6%, in 1999. The increases were due to
increases in the number of consultants, product support and training staff and
increased use of third-party consultants to provide implementation services. As
a means to expand into different geographic and vertical markets, we expect to
increase the number of our consulting, product support and training personnel in
the foreseeable future.

     Sales and Marketing Expenses.  Sales and marketing expenses consist
primarily of personnel costs, commissions, office facilities, travel, and
promotional events such as trade shows, seminars, technical conferences,
advertising and public relations programs. Sales and marketing expenses
increased $195.4 million, or 100.3%, in 2000 and $64.8 million, or 49.8%, in
1999. The increases were due to:

     - We increased the number of our direct sales representatives to 580 at
       December 31, 2000, up from 253 at December 31, 1999 and 184 at December
       31, 1998. This represents a 129.2% increase in our direct sales force in
       2000 and a 37.5% increase in 1999.

                                        16
<PAGE>   17

     - Increased sales commissions due to higher revenues.

     - Increased marketing and promotional activities due to the expansion of
       our suite of e-business solutions.

     Research and Development Expenses.  Research and development expenses
consist of continued software development and product enhancements to existing
software. Software development costs are expensed as incurred until
technological feasibility has been established, at which time such costs are
capitalized until the product is available for general release to customers. To
date, the establishment of technological feasibility of our products and general
release of such software has substantially coincided. As a result, software
development costs qualifying for capitalization have been insignificant;
therefore, we have not capitalized any software development costs other than
those recorded in connection with our acquisitions.

     Research and development expenses increased $85.7 million, or 64.8%, in
2000 and $38.1 million, or 40.4%, in 1999. Research and development expenses as
a percentage of total revenues decreased to 19.3% in 2000 from 23.2% in 1999 and
25.5% in 1998. The decrease in research and development expenses as a percentage
of total revenues resulted from our ability to leverage our resource base to
support a larger organization. The increases in the dollar amount of research
and development expenses were due to increased research and development
personnel by approximately 93.9% in 2000 and approximately 23.5% in 1999. As of
December 31, 2000, our research and development headcount totaled approximately
1,900, up from approximately 1,000 at December 31, 1999 and approximately 800 at
December 31, 1998. Included in the 1,900 headcount total for research and
development at December 31, 2000 were approximately 600 employees added by the
acquisition of Aspect and approximately 30 employees added by the acquisition of
SupplyBase.

     General and Administrative Expenses.  General and administrative expenses
include the personnel and other costs of our finance, legal, accounting, human
resources, information systems and executive departments. General and
administrative expenses increased $33.7 million, or 63.4%, in 2000 and $15.0
million, or 39.3%, in 1999. General and administrative expenses as a percentage
of total revenues decreased to 7.7% in 2000 from 9.3% in 1999 and 10.3% in 1998.
The increases in the dollar amounts of general and administrative expenses were
primarily due to the cost of supporting a 102.0% increase in personnel in 2000
and an 18.9% increase in 1999, as well as increases in the number and size of
our facilities and equipment related to our new corporate headquarters. The
decrease in general and administrative expenses as a percentage of total
revenues resulted from our ability to leverage our resource base to support a
larger organization. We expect total general and administrative expenses to
increase in the foreseeable future due to further growth and expansion of the
company.

     Amortization of Intangibles.  From time to time, we have sought to
supplement the expanding depth and breadth of our product offerings through
technology or business acquisitions. When an acquisition of a business is
accounted for using the purchase method, the amount of the purchase price is
allocated to the fair value of assets acquired, net of liabilities assumed. Any
excess purchase price is allocated to goodwill. Goodwill is amortized over the
life of the asset (typically two to three years). Details of our acquisitions
are presented in Note 2-Business Combinations and Note 3-Asset Acquisition in
the Notes to Consolidated Financial Statements included elsewhere in this
report.

     Amortization of intangibles, including amortization of goodwill, related to
the acquisitions referenced above totaled $1.7 billion, or 153.1% of total
revenues, in 2000. Under current accounting guidance, amortization of these
intangibles will continue through 2003. In February 2001, the Financial
Accounting Standards Board issued a revision to a previously issued exposure
draft covering business combinations proposing new accounting guidance related
to goodwill that would change the amortization methodology. See Note 12-New
Accounting Standards in the Notes to Consolidated Financial Statements included
elsewhere in this report.

     All of our goodwill is associated with the entire company rather than any
specific identifiable asset or product line. Each quarter we evaluate whether an
impairment of this enterprise goodwill may exist by comparing the book value of
the our common stock to the product of (i) the number of shares of common stock
issued and outstanding at the end of the quarter and (ii) the market price of
the common stock at the

                                        17
<PAGE>   18

end of the quarter. If the product of shares and market price exceeds the book
value, impairment does not exist. If the product of shares and market price is
less than book value, we evaluate whether the condition is other than temporary
based (i) primarily on whether fluctuations in the company's stock price
subsequent to the quarter-end result in a product of shares and market price
that exceeds book value and (ii) on all other available evidence. If the product
of shares and market price is continuously less than book value based on daily
closing market prices for the prior six months, we evaluate whether the
condition is other than temporary considering all other available evidence. If
we determine the condition is other than temporary, additional amortization is
recorded for the impairment, equal to the excess book value at the end of the
quarter.

     We may record an additional goodwill amortization charge as of the end of
any quarter, when the product of the number of shares issued and outstanding and
the closing market price of our common stock is less than the book value of our
common stock. We do not believe that we can predict our common stock price and
accordingly, are unable to predict when, if ever, such additional goodwill
amortization might be recorded. At December 31, 2000, we had 405.8 million
common shares issued and outstanding with a book value of $8.5 billion.
Therefore, our common stock price would had to have been below $20.83 per share
before consideration would have been given to recording additional goodwill
amortization. At December 31, 2000, our common stock price was $54.38. Future
calculations of whether an impairment may exist will be affected by any future
issuances or purchases of common stock, by amortization of existing goodwill, by
any goodwill recorded in connection with future acquisitions, by any other
changes to the book value of our common stock, and by our future common stock
price.

     In-Process Research and Development and Acquisition-Related
Expenses.  Technology or business acquisitions may include the purchase of
technology that has not yet been determined to be technologically feasible and
has no alternative future use in its then-current stage of development. The
portion of the purchase price allocated to in-process research and development
is expensed immediately upon the consummation of the acquisition. In making the
purchase price allocation, we consider present value calculations of income, an
analysis of project accomplishments and remaining outstanding items, an
assessment of overall contributions, as well as project risks. The value
assigned to purchased in-process technology is determined by estimating the
costs to develop the acquired technology into commercially viable products,
estimating the resulting net cash flows from the projects, and discounting the
net cash flows to their present value. The revenue projection used to value the
in-process research and development is based on estimates of relevant market
sizes and growth factors, expected trends in technology, and the nature and
expected timing of new product introductions by our competitors and us. The
resulting net cash flows from such projects are based on our estimates of cost
of sales, operating expenses, and income taxes from such projects. Details of
in-process research and development and acquisition related expenses are
presented in Note 2 -- Business Combinations and Note 3 -- Asset Acquisition in
the Notes to Consolidated Financial Statements included elsewhere in this
report.

     The write-off of acquired in-process research and development increased to
9.1% of total revenues in 2000 from 1.1% in 1999 and 2.1% in 1998. In 2000, this
increase is primarily related to the acquisitions of SupplyBase, Aspect and
various IBM assets. In 1999, the charges primarily consisted of acquisition
expenses related to SMART, and in 1998, the charges consisted mostly of
acquisition expenses related to ITLS. We expect to continue to expand through
acquisitions and the resulting write-off of in-process research and development
could vary significantly from year to year.

OTHER INCOME, NET

     Other income, net, consists of interest income on investments partially
offset by interest expense, realized gains/losses on equity investments, foreign
currency exchange transaction gains/losses and other miscellaneous income and
expense. Other income, net, was 1.6% of total revenues in 2000, 1.3% in 1999 and
2.4% in 1998. Other income, net, increased $10.6 million, or 138.5%, in 2000.
The increase was attributable to the combination of higher average investment
balances and overall market interest rates offset by a full year's interest
expense on our convertible notes and net foreign currency exchange transaction
losses. The interest yields on investments and the relative exchange values of
foreign currencies are influenced by the monetary and fiscal policies of the
governments in the countries we operate. The nature, timing and extent of any
impact on our financial statements resulting from changes in those governments'
policies are not predictable.

NON-CASH SETTLEMENT

     On October 10, 2000, we settled a lawsuit filed by a former employee
alleging his right to exercise stock options granted to him in 1996 while he was
employed by us, prior to the initial public offering of our stock. The
settlement resulted in the recognition of a $22.4 million non-cash, pre-tax
charge during the third quarter of 2000. In a separate matter, an employee of a
company we acquired in 1998 is currently disputing the cancellation of stock
options received at the time of the acquisition. Vesting of these options was
dependent upon continued employment; however, the employment was terminated in
2000. We maintain the former employee was not entitled to unvested stock
options.

PROVISION FOR INCOME TAXES

     We recognized income tax expense in 2000 despite our net loss before income
taxes, resulting in a negative effective tax rate. Our effective income tax rate
in 2000 was (2.1)% compared to 51.1% in 1999 and 76.8% in 1998. The effective
income tax rate in 2000, and to a lesser extent in 1999 and 1998, differed from
the U.S. statutory rate primarily due to the non-deductibility of goodwill,
in-process research and development and acquisition-related expenses. Other
items affecting our effective tax rate during the periods presented include
state taxes (net of federal tax benefits), non-deductible meals and
entertainment, deferred tax asset valuation allowances and research and
development tax credits. Excluding the impact of these and other items, our
effective tax rates were 37.5% in 2000, 38.0% in 1999 and 38.5% in 1998.

     As of December 31, 2000 and 1999, we had net deferred tax assets totaling
$356.5 million and $42.0 million. Realization of our deferred tax asset is
dependent upon the U.S. consolidated tax group of companies having sufficient
federal taxable income in future years to utilize our net operating loss
carryforwards before they expire from 2002 through 2020. In 2000, we recognized
a significant tax benefit from the exercise of stock options, which was
reflected as an increase to additional paid-in capital in our financial
statements. We believe it is unlikely a similar annual tax benefit of this
relative magnitude from stock option exercises will be realized in a future
year. Considering our current level of taxable income without a stock option tax
benefit of this magnitude, we believe it is more likely than not that the
deferred tax asset will be realized during the net operating loss carryforward
period. A reduction in our federal taxable income could cause a portion or all
of our net operating loss carryforwards to expire with a corresponding loss of
the related deferred tax asset.

BASIC AND DILUTED EARNINGS PER COMMON SHARE

     Basic and diluted earnings per common share is computed in accordance with
SFAS No. 128, "Earnings Per Share," which requires dual presentation of basic
and diluted earnings per common share for entities with complex capital
structures. Basic earnings per common share is based on net income divided by
the weighted-average number of common shares outstanding during the year.
Diluted earnings per common share includes the dilutive effect of stock options
and warrants granted using the treasury stock method, the effect of contingently
issuable shares earned during the year and shares issuable under the conversion
feature of our convertible notes using the if-converted method. Future
weighted-average shares outstanding calculations will be impacted by the
following factors:

     - The ongoing issuance of common stock associated with stock option
       exercises.

     - The issuance of common shares associated with our employee stock purchase
       plans.

     - Any fluctuations in our stock price, which could cause changes in the
       number of common stock equivalents included in the diluted earnings per
       common share calculation.

     - The issuance of common stock to effect business combinations should we
       enter into such transactions.

     - The issuance of common stock or warrants to effect joint marketing, joint
       development or other similar arrangements should we enter into such
       arrangements.

     - Assumed or actual conversions of debt into common stock with respect to
       our convertible notes.

LIQUIDITY AND CAPITAL RESOURCES

     Historically, we have financed our operations and met our capital
expenditure requirements primarily through cash flows provided from operations,
long-term borrowings and sales of equity securities. Our liquidity and financial
position at December 31, 2000 showed a 32.8% increase in working capital in
2000. Working capital was $776.7 million as of year-end 2000 and $585.0 million
as of year-end 1999. The increase in working capital is primarily attributed to
$192.0 million in net cash provided by operating activities. The net change in
cash and cash equivalents was also positively impacted by the net effect of cash
provided by proceeds from the sale of common stock to employees and exercise of
stock options, offset by cash used in investing activities.

     Net cash provided by operating activities increased 120.6%, net cash used
in investing activities decreased 11.8% and net cash provided by financing
activities decreased 59.5% over 1999 totals. Cash and cash equivalents were
$739.2 million at December 31, 2000, an increase of $284.7 million, or 62.6%,
over balances at December 31, 1999. The increase was the result of $192.0
million in cash generated by operating activities and $150.3 million in cash
provided by financing activities, offset by $57.7 million in cash used in
investing activities. The most significant transactions which adjusted net
income to net cash provided by operations for 2000 were write-offs of in-process
research and development of $101.3 million, depreciation and amortization of
$1.8 billion, deferred income taxes and disqualifying dispositions of $351.1
million, tax benefits from stock option exercises of $326.7 million and the net
increase in accounts receivable of $132.3 million. Significant items that
affected our net cash used in investing activities in 2000 were purchases of
premises and equipment of $87.9 million, cash acquired in purchase transactions
of $55.2 million, direct costs of purchase transactions of $41.0 million, and
net maturities and sales of debt securities and equity investments of $16.9
million. The $150.3 million in cash provided by financing activities was from
proceeds from the sale of common stock to employees and exercises of stock
options.

     Accounts receivable, net of allowance for doubtful accounts, increased
89.4% in 2000. Days sales outstanding (DSO's) in receivables decreased to 73
days as of December 31, 2000 from 83 days as of December 31, 1999. The increase
in accounts receivable was due to a 97.2% increase in total revenue. DSO's
decreased due to strong collection efforts in 2000 that resulted in over $1.1
billion in actual cash collections. There is no assurance that DSO performance
will remain at this level.

     We maintain two, one-year revolving lines of credit of $15.0 million with
separate financial institutions that have an aggregate borrowing capacity of
$30.0 million. There have been no borrowings under these agreements, which are
renewable in August 2001. See Note 6 -- Borrowings in the Notes to Consolidated
Financial Statements included elsewhere in this report.

     On December 10, 1999, we issued an aggregate principal amount of $350.0
million of our 5.25% convertible subordinated notes due in 2006. As of year-end
2000, none of the notes have been converted to common stock. The notes are
convertible at the option of the holder into shares of our common stock at a
conversion price of $38.00 per share at any time prior to maturity. On or after
December 20, 2002, we have the option to redeem, in cash, all or a portion of
the notes that have not been previously converted. See Note 6 -- Borrowings in
the Notes to Consolidated Financial Statements included elsewhere in this
report.

     In the future, we may pursue acquisition of businesses, products and
technologies, or enter into joint venture arrangements, that could complement or
expand our business. Any material acquisition or joint venture could result in a
decrease to our working capital depending on the nature, timing and amount of
consideration to be paid.

     We expect future liquidity will be enhanced to the extent that we are able
to realize the cash benefit from utilization of our net operating loss
carryforwards against future tax liabilities. As of December 31, 2000, we had
$931.3 million in net operating loss carryforwards, which represent up to $349.2
million in future tax benefits. The utilization of the net operating loss
carryforwards is subject to limitations and various expiration dates in years
2002 through 2020.

     We believe that existing cash and cash equivalent balances, short-term
investment balances, available borrowings under the revolving credit agreements
and our anticipated cash flows from operations will satisfy our working capital
and capital expenditure requirements for the foreseeable future. However, any
material

                                        20
<PAGE>   21

acquisitions of complementary businesses, products or technologies or joint
venture arrangements could require us to obtain additional equity or debt
financing.

SENSITIVITY TO MARKET RISKS

     Foreign Currency Risk.  Revenues originating outside of the United States
totaled 34.9%, 31.7% and 19.8% of total revenues in 2000, 1999 and 1998.
Revenues from our European markets totaled 19.9%, 16.4% and 10.8% of total
revenues for the same years. Due to the fact that we conduct business on a
global basis in various foreign currencies, we are exposed to adverse movements
in foreign currency exchange rates. During 2000, 1999 and 1998, our strategy for
managing foreign currency risk was limited to hedging certain significant
accounts receivable that were denominated in a foreign currency. Gains and
losses realized from hedging activities through December 31, 2000 have not been
significant. In January 2001, we established a foreign currency hedging program
utilizing foreign currency forward exchange contracts to hedge various
nonfunctional currency exposures. We expect this program to reduce the effect of
changes in foreign currency exchange rates on our results of operations because
foreign currency transaction gains and losses recorded for accounting purposes
will be offset by gains and losses on the forward contracts. The forward
contracts we enter into will generally have original maturities of one month. We
have not used, nor do we expect to use, forward contracts for trading purposes.

     Interest Rate Risk.  Our investments are subject to interest rate risk.
Interest rate risk is the risk that our financial condition and results of
operations could be adversely affected due to movements in interest rates. We
invest our cash in a variety of interest-earning financial instruments,
including bank time deposits, money market funds and taxable and tax-exempt
variable rate and fixed rate obligations of corporations, municipalities and
local, state and national governmental entities and agencies. These investments
are denominated in U.S. dollars. Cash balances in foreign currencies overseas
are operating balances and are invested in short-term time deposits of the local
operating bank.

     Due to the demand nature of our money market funds and the short-term
nature of our time deposits and debt securities portfolio, these assets are
particularly sensitive to changes in interest rates. As of December 31, 2000,
84.6% of our debt securities and time deposits had original maturities of three
months or less, while 13.3% had original maturities between three months and one
year. If these short-term assets are reinvested in a declining interest rate
environment, we would experience an immediate negative impact on other income.
The opposite holds true in a rising interest rate environment. The Federal
Reserve Board influences the general market rates of interest. Since December
31, 2000, the Federal Reserve Board has decreased the discount rate by 150 basis
points, which has led to a general decline in market interest rates. Assuming
the Federal Reserve Board maintains this position on interest rates, we expect
our average yield on investments to decline in 2001 provided the composition of
our investment portfolio remains the same.

     The weighted-average yield on interest-earning investments held as of
December 31, 2000 was 6.8% compared to 5.3% for investments held as of December
31, 1999. Based on our investment holdings as of December 31, 2000, an immediate
100 basis point decline in the average yield earned on these investments would
reduce our expected annual interest earnings by $6.4 million.

     Market Price Risk.  In addition to investments in debt securities, we
maintain minority equity investments in various privately held and publicly
traded companies for business and strategic purposes. Our investments in
publicly traded companies are subject to market price volatility. As a result of
market price volatility, we experienced a $3.8 million net after-tax unrealized
loss during 2000 on these investments. Our ability to sell certain equity
positions is restricted because the shares held may not have been registered or
other contractual agreements. While these positions were not hedged as of
December 31, 2000, in 2001, we may implement hedging strategies using put and
call options to fix our gains and limit our losses in certain equity positions
until such time as the investments can be sold. The fair value of our
investments in publicly traded companies totaled $13.4 million at December 31,
2000. The fair value of these investments would be $12.0 million given 10%
decreases in each stock's price.

     We have invested in numerous privately held companies, many of which can
still be considered in the start-up or development stages. These investments are
inherently risky as the market for technologies or

                                        21
<PAGE>   22

products they have under development are typically in the early stages and may
never materialize. Further, market conditions for these types of investments
have been deteriorating of late. We could lose our entire investments in these
companies. As of December 31, 2000, our investments in privately held companies
totaled $40.2 million. In 2000, realized losses related to the write-down of
various equity investments totaled $2.8 million, or 7.0% of year-end holdings.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     On January 1, 2001, we adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS 137 and SFAS 138. SFAS
133 requires all derivatives to be recorded at fair value. Unless designated as
hedges, changes in these fair values will be recorded in the income statement.
Fair value changes involving hedges will generally be recorded by offsetting
gains and losses on the hedge and on the hedged item, even if the fair value of
the hedged item is not otherwise recorded. Adoption of this standard did not
have a material effect on our financial statements.

FACTORS THAT MAY AFFECT FUTURE RESULTS

     You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones facing our company. Additional risks and uncertainties that we do not
presently know or that we currently deem immaterial may also impair our business
operations. This report is qualified in its entirety by these risk factors.

     If any of the following risks actually occur, they could materially
adversely affect our business, financial condition or results of operations. In
that case, the trading price of our common stock could decline.

RISKS RELATED TO OUR BUSINESS

OUR FINANCIAL RESULTS MAY VARY SIGNIFICANTLY FROM QUARTER TO QUARTER OR WE MAY
FAIL TO MEET EXPECTATIONS, WHICH WOULD NEGATIVELY IMPACT THE PRICE OF OUR STOCK.

     Our operating results have varied significantly from quarter to quarter in
the past, and we expect our operating results to continue to vary from quarter
to quarter in the future, due to a variety of factors, many of which are outside
of our control.

     Although our revenues are subject to fluctuation, significant portions of
our expenses are not variable in the short term, and we cannot reduce them
quickly to respond to decreases in revenues. Therefore, if revenues are below
expectations, this shortfall is likely to adversely and disproportionately
affect our operating results. Accordingly, we may not maintain positive
operating margins in future quarters. Any of these factors could cause our
operating results to be below the expectations of securities analysts and
investors, which likely would negatively affect the price of our common stock.

THE IMPACT OF CHANGES IN GLOBAL ECONOMIC CONDITIONS ON OUR CUSTOMERS MAY CAUSE
US TO FAIL TO MEET EXPECTATIONS, WHICH WOULD NEGATIVELY IMPACT THE PRICE OF OUR
STOCK.

     Our operating results can vary significantly based upon the impact of
changes in global economic conditions on our customers. More specifically, the
macroeconomic environment entering 2001 is more uncertain than in recent periods
and has the potential to materially and adversely affect us. The revenue growth
and profitability of our business depends on the overall demand for computer
software and services, particularly in the areas in which we compete. Because
our sales are primarily to major corporate customers whose businesses fluctuate
with general economic and business conditions, a softening of demand for
computer software caused by a weakening economy may result in decreased revenues
and lower growth rates. We may be especially prone to this as a result of the
relatively large license transactions we have historically relied upon.
Customers may defer or reconsider purchasing products if they experience a
downturn in their business or if there is a downturn in the general economy.

                                        22

HISTORICALLY, A SMALL NUMBER OF INDIVIDUAL LICENSE SALES HAVE BEEN SIGNIFICANT
IN EACH QUARTERLY PERIOD. THEREFORE, OUR OPERATING RESULTS FOR A GIVEN PERIOD
COULD SUFFER SERIOUS HARM IF WE FAIL TO CLOSE ONE OR MORE LARGE SALES EXPECTED
FOR THAT PERIOD.

     We generally derive a significant portion of revenues in each quarter from
a small number of relatively large license sales with, in some cases, long and
intensive sales cycles. In addition, our expectations of financial results for a
particular quarter frequently assume the successful closing of multiple
substantial license sales that we have targeted to close in that period.
Moreover, due to customer purchasing patterns, we typically realize a
significant portion of our software license revenues in the last few weeks of a
quarter. As a result, we are subject to significant variations in license
revenues and results of operations if we incur any delays in customer purchases.
If in any future period we fail to close one or more substantial license sales
that we have targeted to close in that period, this failure could seriously harm
our operating results for that period.

IMPLEMENTATION OF OUR PRODUCTS IS COMPLEX, TIME-CONSUMING AND EXPENSIVE AND
CUSTOMERS MAY BE UNABLE TO IMPLEMENT OUR PRODUCTS SUCCESSFULLY OR OTHERWISE
ACHIEVE THE BENEFITS ATTRIBUTABLE TO OUR PRODUCTS.

     Our products must integrate with the many existing computer systems and
software programs of our customers. This can be complex, time-consuming and
expensive, and may cause delays in the deployment of our products. Our customers
may be unable to implement our products successfully or otherwise achieve the
benefits attributable to our products. Delayed or ineffective implementation of
our software and services may limit our ability to expand our revenues and may
result in customer dissatisfaction, harm to our reputation and cause partial
non-payment of fees.

WE MAY NOT REMAIN COMPETITIVE, AND INCREASED COMPETITION COULD SERIOUSLY HARM
OUR BUSINESS.

     Our competitors offer a wide variety of e-business solutions including
enterprise software. Relative to us, our competitors may have one or more of the
following advantages:

     - Longer operating history.

     - Greater financial, technical, marketing, sales and other resources.

     - Superior product functionality in specific areas.

     - Greater name recognition.

     - A broader range of products to offer.

     - A larger installed base of customers.

     Current and potential competitors have established, or may establish,
cooperative relationships among themselves or with third parties to enhance
their products, which may result in increased competition. In addition, we
expect to experience increasing price competition as we compete for market
share, and we may not be able to compete successfully with our existing or new
competitors. Any of these conditions could cause substantial harm to our
business, operating results and financial condition.

OUR OBJECTIVE OF INCREASING OUR RECURRING REVENUE STREAMS BY SELLING MARKETPLACE
SERVICES AND CONTENT TO MARKETPLACES AND THEIR PARTICIPANTS IS UNPROVEN AND MAY
BE UNSUCCESSFUL.

     As part of our business strategy, we are offering electronic marketplace
services and content to trading communities and participants in digital
marketplaces. We are currently providing only a limited portion of our intended
i2 TradeMatrix solutions in only a relatively small number of digital trading
communities compared to the potential market for digital trading communities. We
cannot be certain that these trading communities will be operated effectively,
that enterprises will join and remain in these trading communities, or that we
will develop and provide successfully all intended i2 TradeMatrix solutions. If
this business strategy is flawed, or if we are unable to execute it effectively,
our business, operating results and financial condition could be substantially
harmed.
                                        23
<PAGE>   24

WE DEPEND ON OUR STRATEGIC PARTNERS AND OTHER THIRD PARTIES FOR SALES AND
IMPLEMENTATION OF OUR PRODUCTS. IF WE FAIL TO DERIVE BENEFITS FROM OUR EXISTING
AND FUTURE STRATEGIC RELATIONSHIPS, OUR BUSINESS WILL SUFFER.

     From time to time, we have collaborated with other companies, including IBM
and PricewaterhouseCoopers, in areas such as marketing, distribution and
implementation. Maintaining these and other relationships is a meaningful part
of our business strategy. However, some of our current and potential strategic
partners are either actual or potential competitors, which may impair the
viability of these relationships. In addition, some of our relationships have
failed to meet expectations and may fail to meet expectations in the future. A
failure by us to maintain existing strategic relationships or enter into
successful new strategic relationships in the future could seriously harm our
business, operating results and financial condition.

ANY DECREASE IN DEMAND FOR OUR ENTERPRISE PRODUCTS AND SERVICES COULD
SIGNIFICANTLY REDUCE OUR REVENUES.

     We derive a substantial portion of our revenues from licenses of our
enterprise products and related services. Our enterprise products principally
include solutions for supply chain management, supplier relationship management,
customer relationship management and other planning products. We expect license
revenues and maintenance and consulting contracts related to these products to
continue to account for a substantial portion of our revenues for the
foreseeable future. However, competition, technological change or other factors
could decrease demand for, or market acceptance of, these applications. Any
decrease in demand or market acceptance of our enterprise offerings could
substantially harm our business, operating results and financial condition.

WE ARE INVESTING SIGNIFICANT RESOURCES IN DEVELOPING AND MARKETING OUR
MARKETPLACE SOLUTIONS. THE MARKET FOR THESE SOLUTIONS IS NEW AND EVOLVING, AND
IF THIS MARKET DOES NOT DEVELOP AS WE ANTICIPATE, OR IF WE ARE UNABLE TO DEVELOP
ACCEPTABLE SOLUTIONS, SERIOUS HARM WOULD RESULT TO OUR BUSINESS.

     We are investing significant resources in further developing and marketing
enhanced products and services to facilitate conducting business on-line, within
an enterprise and among many enterprises, including public and private
marketplaces. The demand for, and market acceptance of, these products and
services are subject to a high level of uncertainty, especially where
development of our products or services requires a large capital commitment or
other significant commitment of resources. Adoption of e-business software
solutions, particularly by those individuals and enterprises that have
historically relied upon traditional means of commerce and communication, will
require a broad acceptance of new and substantially different methods of
conducting business and exchanging information. These products and services are
often complex and involve a new approach to the conduct of business. As a
result, intensive marketing and sales efforts may be necessary to educate
prospective customers regarding the uses and benefits of these products and
services in order to generate demand. The market for this broader functionality
may not develop, competitors may develop superior products and services, or we
may not develop acceptable solutions to address this functionality. Any one of
these events could seriously harm our business, operating results and financial
condition.

IF WE PUBLISH INACCURATE CATALOG CONTENT DATA, OUR CONTENT SALES COULD SUFFER.

     The accurate publication of catalog content is critical to our customers'
businesses. Our i2 TradeMatrix suite of products offers content management tools
that help suppliers manage the collection and publication of catalog content.
Any defects or errors in these tools or the failure of these tools to accurately
publish catalog content could deter businesses from participating in the i2
TradeMatrix marketplaces, damage our business reputation and harm our ability to
win new customers. In addition, from time to time some of our customers may
submit inaccurate pricing or other inaccurate catalog information. Even though
such inaccuracies are not caused by our work and are not within our control,
such inaccuracies could deter current and potential customers from using our
products and could seriously harm our business, operating results and financial
condition.

                                        24

BECAUSE OUR PRODUCTS COLLECT AND ANALYZE STORED CUSTOMER INFORMATION, CONCERNS
THAT OUR PRODUCTS DO NOT ADEQUATELY PROTECT THE PRIVACY OF CONSUMERS COULD
INHIBIT SALES OF OUR PRODUCTS.

     One of the features of our customer management software applications is the
ability to develop and maintain profiles of consumers for use by businesses.
Typically, these products capture profile information when consumers, business
customers and employees visit an Internet web-site and volunteer information in
response to survey questions concerning their backgrounds, interests and
preferences. Our products augment these profiles over time by collecting usage
data. Although our customer management products are designed to operate with
applications that protect user privacy, privacy concerns nevertheless may cause
visitors to resist providing the personal data necessary to support this
profiling capability. Any inability to adequately address consumers' privacy
concerns could seriously harm our business, financial condition and operating
results.

BECAUSE OUR PRODUCTS REQUIRE THE TRANSFER OF INFORMATION OVER THE INTERNET,
SERIOUS HARM TO OUR BUSINESS COULD RESULT IF OUR ENCRYPTION TECHNOLOGY FAILS TO
ENSURE THE SECURITY OF OUR CUSTOMERS' ONLINE TRANSACTIONS.

     The secure exchange of value and confidential information over public
networks is a significant concern of consumers engaging in online transactions
and interaction. Our customer management software applications use encryption
technology to provide the security necessary to effect the secure exchange of
valuable and confidential information. Advances in computer capabilities, new
discoveries in the field of cryptography or other events or developments could
result in a compromise or breach of the algorithms that these applications use
to protect customer transaction data. If any compromise or breach were to occur,
it could seriously harm our business, financial condition and operating results.

OUR INTERNAL PERFORMANCE OBJECTIVES AND ANY SIGNIFICANT GROWTH IN OUR BUSINESS
AND OPERATIONS LIKELY WOULD INCREASE DEMANDS ON OUR MANAGERIAL AND OPERATIONAL
RESOURCES.

     If rapid growth in the scope of our operating and financial systems and the
geographic distribution of our operations and customers continues, it would
increase demands on our management and operations. Our officers and other key
employees would need to implement and improve our operational, customer support
and financial control systems and effectively expand, train and manage our
employee base. Further, irrespective of growth, we expect that we will be
required to manage an increasing number of relationships with various customers
and other third parties, and we have set a number of demanding performance
objectives and commitments that challenges our operations. We may not be able to
manage future expansion or execute our objectives successfully, and our
inability to do so could seriously harm our business, operating results and
financial condition.

WE MAY NOT SUCCESSFULLY INTEGRATE OR REALIZE THE INTENDED BENEFITS OF RECENT
ACQUISITIONS, AND WE MAY MAKE FUTURE ACQUISITIONS OR ENTER INTO JOINT VENTURES
THAT ARE NOT SUCCESSFUL.

     In the future, we plan to acquire additional businesses, products and
technologies, or enter into joint venture arrangements, that could complement or
expand our business. Management's negotiations of potential acquisitions or
joint ventures and management's integration of acquired businesses, products or
technologies could divert their time and resources. Future acquisitions could
cause us to issue equity securities that would dilute your ownership of us,
incur debt or contingent liabilities, amortize goodwill and other intangibles,
or write off in-process research and development and other acquisition-related
expenses that could seriously harm our financial condition and operating
results. Further, we may not be able to properly integrate acquired businesses,
products or technology with our existing operations, train, retain and motivate
personnel from the acquired business, or combine potentially different corporate
cultures. For example, we currently are integrating Trade Service Corporation
and ec-Content, Inc., which acquisitions closed in March 2001, and we are
preparing to integrate RightWorks Corporation, which acquisition we anticipate
closing in the third quarter of 2001. If we are unable to fully integrate an
acquired business, product or technology or train, retain and motivate personnel
from the acquired business, we may not receive the intended benefits of that
acquisition, which could seriously harm our business, operating results and
financial condition.

THE LOSS OF ANY OF OUR KEY PERSONNEL OR OUR FAILURE TO ATTRACT ADDITIONAL
PERSONNEL COULD SERIOUSLY HARM OUR COMPANY.

     We rely upon the continued service of a relatively small number of key
technical and senior management personnel. Our future success depends on
retaining our key employees and our continuing ability to attract, train and
retain other highly qualified technical and managerial personnel. Relatively few
of our key technical or senior management personnel are bound by employment
agreements. As a result, our employees could resign with little or no prior
notice. We may not be able to attract, assimilate or retain other highly
qualified technical and managerial personnel in the future. Our loss of any of
our key technical and senior management personnel or our inability to attract,
train and retain additional qualified personnel could seriously harm our
business, operating results and financial condition.

IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OR FACE A
CLAIM OF INTELLECTUAL PROPERTY INFRINGEMENT BY A THIRD PARTY, WE COULD LOSE OUR
INTELLECTUAL PROPERTY RIGHTS OR BE LIABLE FOR SIGNIFICANT DAMAGES.

     We rely primarily on a combination of copyright, trademark and trade secret
laws, confidentiality procedures and contractual provisions to protect our
proprietary rights. However, unauthorized parties may attempt to copy aspects of
our products or to obtain and use information that we regard as proprietary.
Policing unauthorized use of our products is difficult, and we cannot be certain
that the steps we have taken will prevent misappropriation of our technology.
This is particularly true in foreign countries where the laws may not protect
proprietary rights to the same extent as the laws of the United States and may
not provide us with an effective remedy against piracy.

     There has been a substantial amount of litigation in the software industry
regarding intellectual property rights. As a result, we may be subject to claims
of intellectual property infringement. Although we are not aware that any of our
products infringe upon the proprietary rights of third parties, third parties
may claim infringement by us with respect to current or future products. Any
infringement claims, with or without merit, could be time-consuming, result in
costly litigation or damages, cause product shipment delays or the loss or
deferral of sales, or require us to enter into royalty or licensing agreements.
If we enter into royalty or licensing agreements in settlement of any litigation
or claims, these agreements may not be on terms acceptable to us. Unfavorable
royalty and licensing agreements could seriously harm our business, operating
results and financial condition.

WE CURRENTLY FACE MATERIAL LITIGATION AND ARE MORE LIKELY TO CONTEND WITH
ADDITIONAL LITIGATION IN THE FUTURE DUE TO THE VOLATILITY OF OUR STOCK PRICE.

     We face litigation that could have a material adverse effect on our
business, financial condition and results of operations. We and certain of our
directors and executive officers are named as defendants in several private
securities class action lawsuits relating to our alleged failure to disclose
material information regarding a customer implementation. While we intend to
vigorously dispute these allegations, it is possible that we may be required to
pay substantial damages or settlement costs which could have a material adverse
effect on our financial condition or results of operation. Regardless of the
outcome of these matters, it is likely that we will incur substantial defense
costs and such actions may cause a diversion of management time and attention.
Due to the volatility of the stock market and particularly the stock prices of
Internet-related companies, it is more likely that we will face additional class
action lawsuits in the future.

BECAUSE OF OUR SIGNIFICANT INTERNATIONAL OPERATIONS, WE FACE RISKS ASSOCIATED
WITH INTERNATIONAL SALES AND OPERATIONS THAT COULD HARM OUR COMPANY.

     Our international operations are subject to risks inherent in international
business activities. In addition, we may expand our international operations in
the future, which would increase our exposure to these risks. The risks we face
internationally include:

     - Difficulties and costs of staffing and managing geographically disparate
       operations.

     - Longer accounts receivable payment cycles in certain countries.

     - Compliance with a variety of foreign laws and regulations.

     - Overlap of different tax structures.

     - Meeting import and export licensing requirements.

     - Trade restrictions.

     - Changes in tariff rates.

     - Changes in general economic conditions in international markets.

CHANGES IN THE VALUE OF THE U.S. DOLLAR, AS COMPARED TO THE CURRENCIES OF
FOREIGN COUNTRIES WHERE WE TRANSACT BUSINESS, COULD HARM OUR OPERATING RESULTS.

     To date, our international revenues have been denominated primarily in U.S.
dollars. However, the majority of our international expenses, including the
wages of approximately 2,000 non-U.S. employees, and an increasing percentage of
international revenues, have been denominated in currencies other than the U.S.
dollar. Therefore, changes in the value of the U.S. dollar as compared to these
other currencies may adversely affect our operating results. As our
international operations expand, we expect to use an increasing number of
foreign currencies, causing our exposure to currency exchange rate fluctuations
to increase. We have implemented limited hedging programs to mitigate our
exposure to currency fluctuations affecting international accounts receivable,
cash balances and intercompany accounts, but we do not hedge our exposure to
currency fluctuations affecting international expenses and other commitments.
For the foregoing reasons, currency exchange rate fluctuations have caused, and
likely will continue to cause, variability in our cost to settle foreign
currency denominated liabilities, which could seriously harm our future
business, results of operations and financial condition.

OUR SOFTWARE IS COMPLEX AND MAY CONTAIN UNDETECTED ERRORS.

     Our software programs are complex and may contain undetected errors or
"bugs." Although we conduct extensive testing, we may not discover bugs until
our customers install and use a given product or until the volume of services
that a product provides increases. On occasion, we have experienced delays in
the scheduled introduction of new and enhanced products because of bugs.
Undetected errors could result in loss of customers or reputation, adverse
publicity, loss of revenues, delay in market acceptance, diversion of
development resources, increased insurance costs or claims against us by
customers, any of which could seriously harm our business, operating results and
financial condition.

WE MAY BECOME SUBJECT TO PRODUCT LIABILITY CLAIMS THAT COULD SERIOUSLY HARM OUR
BUSINESS.

     Our software products generally are used by our customers only in mission
critical applications where component failures could cause significant damages.
To mitigate this exposure, our license agreements typically seek to limit our
exposure to product liability claims from our customers. However, these contract
provisions may not preclude all potential claims. Additionally, our general
liability insurance may be inadequate to protect us from all liability that we
may face. We have not experienced any product liability claims to date. Product
liability claims could require us to spend significant time and money in
litigation or to pay significant damages. As a result, any claim, whether or not
successful, could harm our reputation and business, operating results and
financial condition.

OUR EXECUTIVE OFFICERS AND DIRECTORS HAVE SIGNIFICANT INFLUENCE OVER STOCKHOLDER
VOTES.

     As of March 26, 2001, our executive officers and directors together
beneficially owned approximately 32.0% of the total voting power of our company.
Accordingly, these stockholders have significant influence in determining the
composition of our Board of Directors and other significant matters presented to
a vote of stockholders, including amendments to our certificate of
incorporation, a substantial sale of assets or other major corporate transaction
or a non-negotiated takeover attempt. Such concentration of ownership may
discourage a potential acquirer from making an offer to buy our company that
other stockholders might find favorable which, in turn, could adversely affect
the market price of our common stock.

OUR CHARTER AND BYLAWS HAVE ANTI-TAKEOVER PROVISIONS.

     Provisions of our Certificate of Incorporation and our Bylaws as well as
Delaware law could make it more difficult for a third party to acquire us, even
if doing so would be beneficial to our stockholders. We are subject to the
provisions of Section 203 of the Delaware General Corporation Law, which
restricts certain business combinations with interested stockholders. The
combination of these provisions may inhibit a non-negotiated merger or other
business combination.

OUR STOCK PRICE HISTORICALLY HAS BEEN VOLATILE, WHICH MAY MAKE IT MORE DIFFICULT
FOR YOU TO RESELL COMMON STOCK WHEN YOU WANT AT PRICES YOU FIND ATTRACTIVE.

     The market price of our common stock has been highly volatile in the past,
and may continue to be volatile in the future. For example, during the first
quarter of 2001, the market price of our common stock on the Nasdaq National
Market has fluctuated between $12.56 and $61.00 per share. The following factors
may significantly affect the market price of our common stock:

     - Quarterly variations in our results of operations.

     - Announcement of new products, product enhancements, joint ventures and
       other alliances by our competitors or us.

     - Technological innovations by our competitors or us.

     - General market conditions or market conditions specific to particular
       industries.

     - Perceptions in the marketplace of performance problems involving our
       products and services.

     In particular, the stock prices of many companies in the technology and
emerging growth sectors have fluctuated widely, often due to events unrelated to
their operating performance. These fluctuations may harm the market price of our
common stock.

RISKS RELATED TO OUR INDUSTRY

THE CUSTOMERS IN THE MARKETS IN WHICH WE COMPETE DEMAND RAPID TECHNOLOGICAL
CHANGE, INCLUDING THE EXPECTATION THAT OUR EXISTING OFFERINGS WILL CONTINUE TO
PERFORM MORE EFFICIENTLY AND THAT WE WILL CONTINUE TO INTRODUCE NEW PRODUCT
OFFERINGS. IF WE DO NOT RESPOND TO THE TECHNOLOGICAL ADVANCES REQUIRED BY THE
MARKETPLACE, WE COULD SERIOUSLY HARM OUR BUSINESS.

     Enterprises are increasing their focus on decision-support solutions for
e-business challenges. As a result, they are requiring their application
software vendors to provide greater levels of functionality and broader product
offerings. Moreover, competitors continue to make rapid technological advances
in computer hardware and software technology and frequently introduce new
products, services and enhancements. We must continue to enhance our current
product line and develop and introduce new products and services that keep pace
with the technological developments of our competitors. We must also satisfy
increasingly sophisticated customer requirements. If we cannot successfully
respond to the technological advances of others, or if our new products or
product enhancements and services do not achieve market acceptance, these events
could negatively impact our business, operating results and financial condition.

                                        28

OUR OFFERINGS REQUIRE THE USE OF THE INTERNET TO TAKE FULL ADVANTAGE OF THE
FUNCTIONALITY THAT THEY PROVIDE, AND SO, IF USE OF THE INTERNET FOR COMMERCE AND
COMMUNICATION DOES NOT INCREASE AS WE ANTICIPATE, OUR BUSINESS WILL SUFFER.

     We are offering new and enhanced products and services, which depend on
increased acceptance and use of the Internet as a medium for commerce and
communication. Rapid growth in the use of the Internet is a recent phenomenon.
As a result, acceptance and use may not continue to develop at historical rates,
and a sufficiently broad base of business customers may not adopt or continue to
use the Internet as a medium of commerce. Demand and market acceptance for
recently introduced services and products over the Internet are subject to a
high level of uncertainty, and there exist a limited number of proven services
and products.

RELEASES OF AND PROBLEMS WITH NEW PRODUCTS MAY CAUSE PURCHASING DELAYS, WHICH
WOULD HARM OUR REVENUES.

     Our practice and the practice in the industry is to periodically develop
and release new products and enhancements. As a result, customers may delay
their purchasing decisions in anticipation of our new or enhanced products, or
products of competitors. Delays in customer purchasing decisions could seriously
harm our business and operating results. Moreover, significant delays in the
general availability of new releases, significant problems in the installation
or implementation of new releases, or customer dissatisfaction with new releases
could seriously harm our business, operating results and financial condition.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of
i2 Technologies, Inc.

We have audited the accompanying consolidated balance sheets of i2 Technologies,
Inc. (a Delaware corporation) as of December 31, 2000 and 1999, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 2000. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of i2 Technologies, Inc. as of
December 31, 2000 and 1999, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 2000, in
conformity with accounting principles generally accepted in the United States.

                          (TABLE DOLLARS IN THOUSANDS)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Nature of Operations.  We are a leading provider of dynamic value-chain
software solutions that may be used by enterprises to optimize business
processes both internally and among trading partners. Our solutions are designed
to help enterprises improve efficiencies, collaborate with suppliers and
customers, respond to market demands and engage in dynamic business interactions
over the Internet. Our products consider the conditions of companies to optimize
key business processes -- from product design to customer relationships. Our
products are designed to help customers, partners, suppliers and service
providers conduct business together and offer a technology infrastructure
supporting collaboration, commerce and content. Our product suites include
software solutions for supply chain management, supplier relationship management
and customer relationship management. We also provide content and content
management solutions as well as a platform for integration and administration of
private and public electronic marketplaces. Our product suites may be used by
our customers to align their value chain to serve their customers. We also
provide services such as consulting, training and maintenance in support of
these offerings.

     Principles of Consolidation.  The consolidated financial statements include
the accounts of i2 Technologies, Inc. and its majority owned subsidiaries. All
significant intercompany balances and transactions have been eliminated in
consolidation.

     All share and per share data in this report reflect the two-for-one stock
splits of our common stock paid as 100% stock dividends on December 5, 2000,
February 17, 2000 and June 2, 1998.

     We acquired InterTrans Logistics Solutions Limited (ITLS) in 1998 and Sales
Marketing Administration Research Tracking Technologies, Inc. (SMART) in 1999.
Each of these business combinations was accounted for as a pooling-of-interests.
Accordingly, the accompanying consolidated financial statements give retroactive
effect to the combinations for all periods presented. In 2000, we acquired
SupplyBase, Inc. (SupplyBase) and Aspect Development, Inc. (Aspect). Each of
these transactions was accounted for as a purchase business combination.
Accordingly, the results of operations of SupplyBase and Aspect have been
included with our results of operations since their respective acquisition
dates. A more detailed discussion of business combinations is provided in Note
2 -- Business Combinations.

     Use of Estimates.  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

     Cash and cash equivalents.  Cash and cash equivalents include cash on hand,
demand deposits with financial institutions and short-term time deposits and
other liquid investments in debt securities with initial maturities of less than
three months.

     Investments.  Investments in debt securities are classified as held to
maturity and carried at amortized cost when management has the positive intent
and ability to hold them to maturity. Investments in debt securities are
classified as available for sale when they might be sold before maturity.
Investments in marketable equity securities are classified as available for
sale. Investments in equity securities with no active market are carried at
cost. Securities available for sale are carried at fair value, with unrealized
holding gains and losses reported in other comprehensive income. Management
determines the appropriate classification of securities at the time of purchase.

     Interest income includes amortization of purchase premiums and discounts.
Gains and losses on sales are based on the amortized cost of the security sold.
Securities are written down to fair value when a decline in fair value is not
temporary.

     Financial Instruments.  Financial instruments that potentially subject us
to a concentration of credit risk consist principally of investments and
accounts receivable. Cash on deposit is held with financial institutions

with high credit standings. Debt security investments are in highly rated
corporations and municipalities as well as agencies of the U.S. government. In
addition, we regularly monitor financial information related to our equity
investments. Our customer base consists of large numbers of geographically
diverse customers dispersed across many industries. As a result, concentration
of credit risk with respect to accounts receivable is not significant. However,
we periodically perform credit evaluations of our customers and maintain
reserves for potential losses. We have used and expect to continue to use
foreign exchange contracts to hedge the risk in receivables denominated in
foreign currencies. Risk of non-performance by counterparties to such contracts
is minimal due to the size and credit standings of the financial institutions
used. Our foreign exchange contracts outstanding at December 31, 2000 and 1999
were not material. Gains and losses on foreign exchange contracts have also not
been material to date.

     Premises and Equipment.  Premises and equipment are recorded at cost and
are depreciated over their useful lives ranging from three to seven years using
the straight-line method. Leasehold improvements are amortized over shorter of
the expected term of the lease or estimated useful life.

     Goodwill and Purchased Intangible Assets.  Goodwill, acquired technology
and other intangible assets related to business acquisitions are amortized on a
straight-line basis over periods of two to five years. All of our goodwill is
associated with our entire company rather than any specific identifiable asset
or product line. Each quarter we evaluate whether an impairment of this
enterprise goodwill may exist by comparing the book value of the our common
stock to the product of (i) the number of shares of common stock issued and
outstanding at the end of the quarter and (ii) the market price of the common
stock at the end of the quarter. If the product of shares and market price
exceeds the book value, impairment does not exist. If the product of shares and
market price is less than book value, we evaluate whether the condition is other
than temporary based (i) primarily on whether fluctuations in the company's
stock price subsequent to the quarter-end result in a product of shares and
market price that exceeds book value and (ii) on all other available evidence.
If the product of shares and market price is continuously less than book value
based on daily closing market prices for the prior six months, we evaluate
whether the condition is other than temporary considering all other available
evidence. If we determine that the condition is other than temporary, additional
amortization is recorded for the impairment, equal to the excess book value at
the end of the quarter.

     We may record an additional goodwill amortization charge as of the end of
any quarter, when the product of the number of shares issued and outstanding and
the closing market price of our common stock is less than the book value of our
common stock. We do not believe that we can predict our common stock price and
accordingly, are unable to predict when, if ever, such additional goodwill
amortization might be recorded. At December 31, 2000, we had 405.8 million
common shares issued and outstanding with a book value of $8.5 billion.
Therefore, our common stock price would had to have been below $20.83 per share
before consideration would have been given to recording additional goodwill
amortization. At December 31, 2000, our common stock price was $54.38. Future
calculations of whether an impairment may exist will be affected by any future
issuances or purchases of common stock, by amortization of existing goodwill, by
any goodwill recorded in connection with future acquisitions, by any other
changes to the book value of our common stock, and by our future common stock
price.

     In-Process Research and Development.  Technology or business acquisitions
may include the purchase of technology that has not yet been determined to be
technologically feasible and has no alternative future use in its then-current
stage of development. The portion of the purchase price allocated to in-process
research and development is expensed immediately upon the consummation of the
acquisition. In making the purchase price allocation, we consider present value
calculations of income, an analysis of project accomplishments and remaining
outstanding items, an assessment of overall contributions, as well as project
risks. The value assigned to purchased in-process technology is determined by
estimating the costs to develop the acquired technology into commercially viable
products, estimating the resulting net cash flows from the projects, and
discounting the net cash flows to their present value. The revenue projection
used to value the in-process research and development is based on estimates of
relevant market sizes and growth factors, expected trends

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

in technology, and the nature and expected timing of new product introductions
by our competitors and us. The resulting net cash flows from such projects are
based on our estimates of cost of sales, operating expenses, and income taxes
from such projects.

     Long-Lived Assets.  Premises and equipment, goodwill associated with
specific identifiable assets and other long-term assets are reviewed for
impairment quarterly, or when events indicate their carrying amount may not be
recoverable from future undiscounted cash flows in accordance with the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 121. If
impaired, assets are recorded at fair value. Other long-term assets include
software, information databases and installed customer base/relationships
acquired from third parties or in business combinations.

     Capitalized Research and Development Costs.  In accordance with Statement
of Financial Accounting Standards (SFAS) No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased, or Otherwise Marketed," software
development costs are expensed as incurred until technological feasibility has
been established, at which time such costs are capitalized until the product is
available for general release to customers. To date, the establishment of
technological feasibility of our products has substantially coincided with the
general release of such software. As a result, software development costs
qualifying for capitalization under SFAS 86 have been insignificant and,
therefore, we have not capitalized any such costs other than those recorded in
connection with our acquisitions.

     Revenue Recognition.  Revenues consist of software license revenues,
service revenues, and maintenance revenues, and are recognized in accordance
with Statement of Position (SOP) 97-2, "Software Revenue Recognition," as
modified by SOP 98-9, "Modification of SOP 97-2, Software Revenue Recognition
with Respect to Certain Transactions," and SEC Staff Accounting Bulletin (SAB)
101, "Revenue Recognition."

     Software license revenues are recognized upon shipment, provided fees are
fixed and determinable and collection is probable. Revenue for agreements that
include one or more elements to be delivered at a future date is recognized
using the residual method. Under the residual method, the fair value of the
undelivered elements is deferred, and the remaining portion of the agreement fee
is recognized as revenue. If fair values have not been established for certain
undelivered elements, revenue is deferred until those elements have been
delivered, or their fair values have been determined. Agreements that include a
right to unspecified future products are recognized ratably over the term of the
agreement. License fees from reseller agreements are generally based on the
sublicenses granted by the reseller and recognized when the license is sold to
the end customer. Licenses to our content databases are recognized over the
terms of the agreements. Fees from licenses sold together with services are
generally recognized upon shipment, provided fees are fixed and determinable,
collection is probable, payment of the license fee is not dependent upon the
performance of the consulting services and the consulting services are not
essential to the functionality of the licensed software.

     Service revenues are primarily derived from fees for implementation,
consulting and training services and are generally recognized under service
agreements in connection with initial license sales and as the services are
performed.

     Maintenance revenues are derived from technical support and software
updates provided to customers. Maintenance revenue is recognized ratably over
the term of the maintenance agreement.

     Payments received in advance of revenue recognized are classified as
deferred revenue in the Consolidated Balance Sheets.

     We warrant our products will function substantially in accordance with
documentation provided to customers. To date, we have not incurred any
significant expenses related to warranty claims.

     No individual customer accounted for more than 10% of total revenues during
any of the periods presented.

     Income Taxes.  Income tax expense is the total of the current year income
tax due or refundable and the change in deferred tax assets and liabilities.
Deferred tax assets and liabilities are the expected future tax
                                       F-8

amounts for the temporary differences between carrying amounts and tax bases of
assets and liabilities, computed using enacted tax rates. A valuation allowance,
if needed, reduces deferred tax assets to the expected amount to be realized.

     Basic and Diluted Earnings Per Common Share.  Basic and diluted earnings
per common share is computed in accordance with SFAS No. 128, "Earnings Per
Share," which requires dual presentation of basic and diluted earnings per
common share for entities with complex capital structures. Basic earnings per
common share is based on net income divided by the weighted-average number of
common shares outstanding during the period. Diluted earnings per common share
includes the dilutive effect of stock options and warrants granted using the
treasury stock method, the effect of contingently issuable shares earned during
the period and shares issuable under the conversion feature of our convertible
notes using the if-converted method. The computations also give retroactive
effect to the exchange of common shares in connection with the ITLS and SMART
acquisitions (see Note 2 -- Business Combinations). A reconciliation of the
weighted-average shares used in calculating basic earnings per common share and
the weighted average common shares used in calculating diluted earnings per
common share for 2000, 1999 and 1998 is provided in Note 7 -- Stockholders'
Equity and Earnings Per Common Share.

     Stock-Based Compensation Plans.  Employee compensation expense under stock
option plans is reported only if options are granted below market price at grant
date in accordance with APB Opinion No. 25. SFAS No. 123, "Accounting for Stock
Based Compensation," requires pro forma disclosures of net income and earnings
per share for companies not adopting its fair value accounting method for
stock-based employee compensation. The pro forma disclosures shown in Note
8 -- Employee Benefit Plans use the fair value method of SFAS No. 123 to measure
expense for options granted using an option-pricing model to estimate fair
value.

     Deferred Compensation.  Deferred compensation is recorded as a component of
stockholders' equity for stock options issued to non-employees. The compensation
is valued as the services are performed and recognized over the service period.

     Foreign Currency Translation.  The functional currency for the majority of
our foreign subsidiaries is the local currency. Assets and liabilities are
translated at exchange rates in effect at the balance sheet date while income
and expense amounts are translated at average exchange rates during the period.
The resulting translation adjustments are disclosed as a separate component of
stockholders' equity and other comprehensive income. Transaction gains and
losses arising from transactions denominated in a non-functional currency and
due to changes in exchange rates are recorded in "other income, net" in the
Consolidated Statements of Operations.

     Fair Values of Financial Instruments.  Fair values of financial instruments
are estimated using relevant market information and other assumptions. Fair
value estimates involve uncertainties and matters of significant judgment
regarding interest rates, credit risk and other factors, especially in the
absence of broad markets for particular items. Changes in assumptions or in
market conditions could significantly affect the estimates. The estimated fair
value approximates carrying value for all financial instruments except
securities and long-term debt. Fair values of securities are based on quoted
market prices or dealer quotes. If a quoted market price is not available, fair
value is estimated using quoted market prices for similar instruments. The fair
value of long-term debt is estimated by discounting future cash flows using the
interest rates currently offered for similar debt of similar remaining maturity.

     Comprehensive Income.  Comprehensive income is reported for all periods.
Comprehensive income includes both net income and other comprehensive income,
which includes the change in unrealized gains and losses on available-for-sale
securities and foreign currency translation adjustments.

     Reclassifications.  Some items in prior year financial statements have been
reclassified to conform to the current year presentation.

     During 1999, we incurred $6.6 million in acquisition related expenses in
connection with the SMART pooling acquisition, as well as other acquisitions
accounted for using the purchase method. During 1998, we incurred $7.6 million
in acquisition related expenses in connection with the ITLS pooling acquisition,
as well as other purchase acquisitions. These costs included investment banking,
legal and accounting fees and expenses, amortization of acquisition-related
intangible assets and the write-off of in-process research and development.

SUPPLYBASE

     On April 28, 2000, we completed our acquisition of SupplyBase, a leading
developer of high-end interactive database products, services and supply chain
management tools for managing custom content. We issued or reserved for issuance
3.6 million shares of our common stock with a fair market value of $345.5
million in exchange for all outstanding stock, options and warrants of
SupplyBase. In connection with the acquisition, we incurred transaction costs
consisting primarily of professional fees of $6.8 million, resulting in a total
purchase price of $352.3 million. The acquisition was accounted for as a
purchase business combination; accordingly, the results of operations of
SupplyBase have been included with our results of operations since April 28,
2000.

</Table>

     $15.7 million of the purchase consideration was allocated to other
intangible assets, including developed technology ($2.8 million), assembled
workforce ($1.2 million) and content databases ($11.7 million), with these
amounts being amortized over two to three years. Goodwill is being amortized
over three years.

     In connection with our acquisition of SupplyBase, we allocated $6.4
million, or 1.8%, of the purchase price to in-process research and development
projects. As of the acquisition date, SupplyBase was conducting design,
development, engineering and testing activities associated with the completion
of its SupplyBase.manager version 1.75/sb.exchange version 1.0 and
SupplyBase.manager version 2.0. SupplyBase.manager version 1.75 includes
strategic enhancements of application hosting and bidding environments.
SupplyBase.manager version 2.0 includes ERP integration, parallel workflow,
value-added quote comparisons and additional market driven functionality. These
products under development at the valuation date represented next-generation
technologies that were expected to address emerging market demands for B2B
e-commerce content management.

     At the acquisition date, the technologies under development ranged from 5%
to 75% complete based on engineering man-month data and technological progress.
SupplyBase had spent $1.2 million on the in-process projects, and expected to
spend approximately $2.0 million to complete all phases of the research and
development. Anticipated completion dates ranged from three to nine months.

     Aggregate revenues for the developmental SupplyBase products were estimated
to grow at a compounded annual growth rate of approximately 200% for the three
years following introduction, assuming the successful completion and market
acceptance of the major research and development programs. The estimated
revenues for the in-process projects were expected to peak within three years of
product completion and then decline sharply as other new products and
technologies enter the market.

     The rates utilized to discount the net cash flows to their present value
were based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the successful development of the
projects, a discount rate of 25% was used to value the in-process research and
development. The discount rate utilized was higher than the our weighted-average
cost of capital due to the inherent uncertainties surrounding the successful
development of the purchased in-process technology, the useful life of such
technology, the profitability levels of the technology, and the uncertainty of
technological advances that are unknown at this time.

     We completed SupplyBase.manager version 1.75 in September 2000 in
accordance with the plans outlined above. SupplyBase.manager version 2.0's
technology and functionality was integrated into the SRM Design, Manufacturing
and Collaboration solutions that were acquired related to our acquisition of
Aspect. The new SRM Product, which also included integration with other
internally developed technologies, was released in the first quarter of 2001.
Our new SRM product release rendered SupplyBase.manager version 1.75, version
1.80 and the acquired in-process technology of SupplyBase.manager 2.0
technologically obsolete and we no longer sell these products. Actual results
were lower than forecasts with respect to revenues generated by the acquired

ASPECT

     On June 9, 2000, we completed our acquisition of Aspect the leading
developer of collaborative solutions for standardized content management and
inbound supply chain solutions for business-to-business marketplaces. We issued
or reserved for issuance 67.5 million shares of our common stock with a fair
market value of $6.4 billion and exchanged options to purchase 28.5 million
shares of our common stock with a fair value of $2.4 billion. The fair value of
the exchanged options was valued using the Black-Scholes options pricing model
with the following assumptions: expected volatility of 0.84, weighted-average
risk-free interest rate of 5.60%, expected terms ranging from 1-4 years and no
expected dividends. In connection with the acquisition, we incurred transaction
costs consisting primarily of professional fees of $39.5 million, resulting in a
total purchase price of $8.8 billion. The acquisition was accounted for as a
purchase business combination; accordingly, the results of operations of Aspect
have been included with our results of operations since June 9, 2000.

     The total purchase price paid for the Aspect acquisition was allocated
based on the estimated fair values of the assets acquired, as follows:

     $217.0 million of the purchase consideration was allocated to other
intangible assets, including developed technology ($81.0 million), assembled
workforce ($10.0 million), content databases ($84.0 million) and customer lists
($42.0 million), with these amounts being amortized over two to three years.
Goodwill is being amortized over three years.

     In connection with the acquisition of Aspect, we allocated $83.0 million,
or 0.9%, of the purchase price to in-process research and development projects.
As of the acquisition date, Aspect was conducting design, development,
engineering and testing activities associated with the completion of its eCSM
and eMarketplace Solutions programs. The eCSM Solutions include eSource, eDesign
and eOperate. eCSM is a complete knowledge management and decision support
solution for commodity management, supplier management, contract management,
collaboration and material rationalization. eMarketplace is a web-based B2B
e-commerce technology for content management and e-commerce web enablement
projects. The eCSM and eMarketplace Solutions under development at the valuation
date represented next-generation technologies that were expected to address
emerging market demands for B2B e-commerce content management.

     At the acquisition date, the technologies under development ranged from 54%
to 59% complete based on engineering man-month data and technological progress.
Aspect had spent $8.1 million on the in-process projects, and expected to spend
approximately $8.8 million to complete all phases of the research and
development. Anticipated completion dates ranged from two to twelve months.

     Aggregate revenues for the developmental Aspect products were estimated to
grow at a compounded annual growth rate of approximately 125% for the three
years following introduction, assuming the successful completion and market
acceptance of the major research and development programs. The estimated
revenues for the in-process projects were expected to peak within three years of
product completion and then decline sharply as other new products and
technologies enter the market.

     The rates utilized to discount the net cash flows to their present value
were based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the successful development of the
projects, a discount rate of 20% was used to value the in-process research and
development. The discount rate utilized was higher than our weighted-average
cost of capital due to the inherent uncertainties surrounding the successful
development of the purchased in-process technology, the useful life of such
technology, the profitability levels of the technology, and the uncertainty of
technological advances that are unknown at this time.

     We have completed all of the original research and development projects in
accordance with the plans outlined above. Additionally, subsequent versions of
existing software have been expanded with several other projects and integrated
into our overall product solutions. The majority of the projects were completed
on schedule, with some delays occurring due to changes in technological and
market requirements for B2B software. Actual results have been lower than
forecasts with respect to revenues generated by the acquired in-process research
and development.

     The following summary, prepared on an unaudited pro forma basis, reflects

     The pro forma results are not necessarily indicative of what would have
occurred if the acquisitions had been in effect for the periods presented. In
addition they are not intended to be a projection of future results and do not
reflect any synergies that might be affected from combined operations. The
charges for in-process research and development have not been included in the
unaudited pro forma results because they are nonrecurring.

OTHER ACQUISITIONS

     We also acquired certain other businesses in 2000, 1999 and 1998 for an
aggregate purchase price of $2.9 million, $5.3 million and $9.2 million, which
included cash, stock, assumed liabilities and acquisition costs. These
acquisitions were accounted for as purchase business combinations. Accordingly,
we allocated the purchase prices based on the fair value of assets acquired and
liabilities assumed. A portion of the purchase price of these transactions was
identified, using proven valuation procedures and techniques, as intangible
assets. This allocation represents the estimated fair value based on
risk-adjusted cash flows related to the in-process research and development
projects. The revenue projections used to value the in-process research and
development were based on estimates of relevant market sizes and growth factors,
expected trends in technology and the nature and expected timing of new product
introductions by us and our competitors. At the date of each acquisition, the
products under development had not reached technological feasibility and had no
alternative future use. We expensed $2.4 million, $3.3 million and $4.7 million
in 2000, 1999 and 1998, as in-process research and development and
acquisition-related costs at each acquisition date. The value assigned to
in-process research and development is comprised of various research and
development projects. These projects include the introduction of new
technologies as well as revisions of enhancements to certain acquired
technologies. There is risk associated with the completion of the projects, and
there is no assurance that each will attain either technological feasibility or
commercial success.

     Amortization of goodwill, acquired technology, other intangible assets, and
the write-off of in-process research and development totaled $1.9 billion in
2000, $5.1 million in 1999 and $5.4 million in 1998.

TRADE SERVICE CORPORATION/EC-CONTENT

     On December 27, 2000, we entered into a definitive agreement to acquire
Trade Services Corporation, a leading provider of maintenance, repair and
overhaul (MRO) content and its affiliate ec-Content, Inc., which develops and
manages content for digital marketplaces, e-procurement and supplier
syndication. Pursuant to the amended agreement, we purchased all the outstanding
stock of both companies for approximately $74.1 million, including acquisition
related costs. The total purchase price includes $5.0 million in cash, 800,000
shares of our common stock with a fair market value of $12.4 million, a
convertible promissory note currently valued at $56.1 million and approximately
$0.6 million in acquisition costs. This acquisition closed on March 23, 2001 and
will be accounted for using the purchase method.

3. ASSET ACQUISITION

     On March 27, 2000, we purchased various software assets, cross-patent
rights and software licenses with an aggregate value of $234 million from IBM in
exchange for 2.6 million shares of our common stock. In connection with our
acquisition of these assets from IBM, we allocated $8.9 million, or 3.8%, of the
purchase price to in-process research and development projects. As of the
acquisition date, IBM was conducting design, development, engineering and
testing activities associated with the completion of its Makaro and Paper Mill
Scheduler Products. These products under development at the valuation date
represented next-generation technologies that were expected to address retailer
and paper-mill scheduling and planning software.

     At the acquisition date, the technologies under development ranged from 73%
to 85% complete based on engineering man-month data and technological progress.
IBM had spent $2.8 million on the in-process projects, and expected to spend
approximately $0.8 million to complete all phases of the research and
development. Anticipated completion dates ranged from two to twelve months.

     Aggregate revenues for the developmental IBM products were estimated to
grow at a compounded annual growth rate of approximately 24% from 2001 to 2007,
assuming the successful completion and market acceptance of the major research
and development programs.

     The rates utilized to discount the net cash flows to their present value
were based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the successful development of the
projects, a discount rate of 19% was used to value the in-process research and
development. The discount rate utilized was higher than our weighted-average
cost of capital due to the inherent uncertainties surrounding the successful
development of the purchased in-process technology, the useful life of such
technology, the profitability levels of the technology, and the uncertainty of
technological advances that are unknown at this time.

     We have completed the original research and development project related to
Makaro in accordance with the plan outlined above. Additionally, the Paper Mill
Scheduler product has been integrated into existing technology of our internally
developed products. Actual results have been lower than forecasts with respect
to revenues generated by the acquired in-process research and development.

     In addition, we may issue to IBM up to an additional $250 million in shares
of our common stock, valued based on a trading average prior to the date of
issuance. We could be obligated to issue some or all of these shares in the
future based on the amount of the revenue we derive from or through IBM during
four annual periods, with the first annual period ending December 31, 2000.
Issuance of this stock will be recorded as a commission or sales discount and
not as an addition to purchase price.

     During 2000 and 1999, all debt securities were classified as available for
sale. The difference between the cost and fair value of these investments was
not material at December 31, 2000 or 1999; therefore, no adjustment has been
made to the historical carrying value of these investments. At December 31,
2000, the carrying value of corporate equity securities included gross
unrealized gains of $2.0 million and gross unrealized losses of $8.1 million. No
unrealized gains or losses were recognized on corporate equity securities at
December 31, 1999.

     Interest and dividend income on investments totaled $43.5 million in 2000,
$9.7 million in 1999 and $7.6 million in 1998. Net realized losses on
investments totaled $1.6 million in 2000. Realized gains and losses in 1999 and
1998 were not material.

6. BORROWINGS

     We maintain two, one-year revolving lines of credit of $15.0 million with
separate financial institutions that have an aggregate borrowing capacity of
$30.0 million. The lines of credit are unsecured and contain customary
restrictive covenants, including covenants requiring us to maintain certain
financial ratios. The lines of credit are not subject to a borrowing base
limitation and borrowings bear interest at LIBOR plus 0.75% to 1.75% per annum,
depending on certain cash ratios. The maximum borrowing levels available under
the lines of credit are reduced by the value of outstanding letters of credit
issued by the lenders on our behalf, $8.1 million and $14.2 million of which
were outstanding at December 31, 2000 and 1999. As of December 31, 2000 and
1999, there were no borrowings outstanding under the lines of credit and we were
in compliance with all covenants. The lines of credit are renewable in August
2001.

     December 10, 1999, we issued an aggregate principal amount of $350.0
million of our 5.25% convertible subordinated notes due in 2006. The notes were
sold at par less an underwriting discount of 2.75% of the principal amount of
the notes. The net proceeds of this offering, after giving effect to discounts,
commissions, premiums and expenses, were $339.9 million. These securities were
issued and sold to Goldman, Sachs & Co., Morgan Stanley & Co. Incorporated and
Credit Suisse First Boston Corporation, as the initial purchasers, in reliance
on the exemption from registration under the Securities Act of 1933, as amended
provided by Section 144A thereof. In connection with this transaction, each of
the initial purchasers represented that it was a "qualified institutional buyer"
within the meaning of the Securities and Exchange Act of 1934. The notes are
convertible at the option of the holder into shares of our common stock at a
conversion price of $38.00 per share at any time prior to maturity. As of
December 31, 2000, none of the notes have been converted to common stock. The
principal balance of the notes totaled $350.0 million at December 31, 2000 and
1999, while the estimated fair value of the notes totaled $358.5 million and
$350.0 million at those dates.

     Interest expensed for borrowings totaled $18.5 million and $1.8 million in
2000 and 1999. Actual cash payments related to interest on borrowings totaled
$18.7 million and $0.7 million during those years. Interest on borrowings was
not significant in 1998.

7. STOCKHOLDERS' EQUITY AND EARNINGS PER COMMON SHARE

     Stock Splits.  On January 14, 2000, our Board of Directors approved a
two-for-one stock split. The stock split was paid as a 100% dividend on February
17, 2000. On October 17, 2000, our Board of Directors approved another
two-for-one stock split that was contingent upon stockholder approval of a
proposed amendment to our certificate of incorporation to increase our
authorized common stock to 2,000,000,000 shares. Our stockholders approved the
proposal at a special meeting held on November 28, 2000 and the stock

split was paid as a 100% stock dividend on December 5, 2000. All prior share and
per share amounts included herein have been adjusted to reflect the stock
splits.

     Earnings Per Common Share.  The weighted-average number of common shares
outstanding for basic and diluted earnings per common share computations for
each reported period was as follows (in thousands):

</Table>

     As a result of the net loss incurred for 2000, the effect of dilutive
securities would have been anti-dilutive to the diluted earnings per common
share computation and were thus excluded. Dilutive securities that would have
otherwise been included in the determination of the weighted-average number of
common shares outstanding for the purposes of computing diluted earnings per
common share included 58.7 million shares issuable under stock options and
warrants and 0.3 million contingently issuable shares earned during the year.

8. EMPLOYEE BENEFIT PLANS

     Employee Retirement Plans.  We have established 401(k) retirement plans
that cover a majority of our employees. Eligible employees may contribute up to
18% of their compensation, subject to certain limitations, to the Retirement
Plans. We may make contributions to the plans at the discretion of the Board;
however, as of December 31, 2000, no contributions have been made.

     Deferred Compensation.  During 2000, 1999 and 1998, we recognized $8.8
million, $0.4 million and $0.6 million of deferred compensation as compensation
expense. As of December 31, 2000 and 1999, the unamortized portion of deferred
compensation totaled $1.4 million and $10.2 million.

     Employee Stock Purchase Plans.  We maintain stock purchase plans for the
benefit of our employees and the employees of our wholly owned subsidiaries. The
purchase plans are designed to allow eligible employees to purchase shares of
common stock through periodic payroll deductions. Payroll deductions may not
exceed the lesser of 15% of a participant's base salary or $25,000 per year, and
employees may purchase a maximum of 8,000 shares per purchase period under the
purchase plans. The purchase price per share is 85% of the lesser of the fair
market value of our common stock on the start of the purchase period or the fair
market value at the end of the purchase period. Participation may be terminated
at any time by the employee and automatically ends upon termination of
employment. We have reserved 10,000,000 shares of common stock for issuance
under the plans. Shares purchased under the plans totaled 709,826 in 2000,
2,026,884 in 1999 and 1,344,778 in 1998. As of December 31, 2000, 4,820,804
shares remained available for purchase under the plans.

     We assumed an employee stock purchase plan maintained by Aspect as a part
of our acquisition. The plan permits eligible employees to purchase common stock
at a discount, but only through payroll deductions, during concurrent 24-month
offering periods. Each offering period is divided into four consecutive
six-month purchase periods. The price at which stock is sold under the Purchase
Plan is equal to 85% of the fair market value of the common stock on the first
day of the offering period or the last day of the purchase period, whichever is
lower. We have reserved 722,447 shares of our common stock for issuance under
this plan. 203,474 shares were issued under this plan in 2000. As of December
31, 2000, 518,973 shares remained available for purchase under the plan. This
plan was terminated upon completion of the final offering period in February
2001.

     1995 Stock Option/Stock Issuance Plan.  The 1995 Stock Option/Stock
Issuance Plan replaced our original 1992 Stock Plan. All options outstanding
under the 1992 Stock Plan were incorporated into the 1995 Plan, however, all
outstanding options under the 1992 Plan continue to be governed by the terms and
conditions of the existing option agreements for those grants. Under the
provisions of the 1995 Plan, as amended, 252,000,000 have been reserved for
issuance. The 1995 Plan is divided into the following three equity programs: (i)
the Discretionary Option Grant Program, (ii) the Stock Issuance Program and
(iii) the Automatic Option Grant Program.

     The Discretionary Option Grant Program provides for the grant of incentive
stock options to employees and for the grant of nonqualified stock options to
employees, directors and consultants. Exercise prices may not be less than 100%
and 85% of the fair market value at the date of grant for incentive options and
nonqualified stock options. Options granted under the Discretionary Option Grant
Program generally vest in four equal annual increments and expire after ten
years. Some options granted under the Discretionary Option Grant Program are
immediately exercisable, subject to a right of repurchase at the original
exercise price for all unvested shares.

     Under the Stock Issuance Program, the Board or a committee of the Board, or
the Plan Administrator, may grant shares of our common stock to any person at
any time, at such prices and on such terms as established by the Plan
Administrator. The purchase price per share cannot be less than 85% of the fair
market value of our common stock on the issuance date.

     Under the Automatic Option Grant Program, each person who is first elected
or appointed as a non-employee Board member shall automatically be granted a
nonqualified option to purchase 8,000 shares of our common stock at the fair
market value on the date of grant. On the date of each Annual Meeting of
Stockholders, each non-employee Board member shall automatically be granted an
additional option to purchase 8,000 shares of our common stock, subject to
certain conditions.

     In connection with the acquisitions of various companies, we have assumed

     In October 1998, the Board approved a plan to reprice a portion of our
outstanding stock options, excluding options held by certain executive officers.
As a result, 15,030,740 options with exercise prices ranging from $3.50 to $8.21
per share were repriced at $3.49 per share, the fair market value on the date of
repricing. For any unvested options included in this repricing, the vesting
schedule was restarted with a vesting period of four years. The repricing has
been reflected in the above table as part of the options granted and canceled
during 1998.

     Under the 1995 Plan, each outstanding option and unvested stock issuance
will be subject to accelerated vesting under certain circumstances upon an
acquisition of us in a merger or asset sale, except to the extent our repurchase
rights with respect to the underlying shares are to be assigned to the successor
corporation. In addition, the Plan Administrator has the discretion to
accelerate vesting of outstanding options upon consummation of any other
transaction that results in a change in control.

     All options outstanding at December 31, 2000, are incentive options except
for 51,296,203 options, which are nonqualified stock options.

     Pro Forma Net Income (Loss) and Earnings Per Share.  Pro forma information
regarding net income (loss) and earnings per share has been determined as if we
had accounted for our employee stock options and shares issued under the
employee stock purchase plans using the fair value method of SFAS No. 123. The
weighted average fair value of options granted in 2000, 1999 and 1998 was
$41.22, $2.15 and $2.31 per option.

                             i2 TECHNOLOGIES, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Fair values of options are estimated at the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions for 2000, 1999 and 1998: Risk-free interest rates of 6.0%, 5.6% and
5.2%; volatility factors of the expected market price of our common stock of
0.93, 0.84 and 0.75; a weighted-average expected life of the options of 4, 3 and
3 years; and no dividend yields. The pro forma impact of stock options issued
under stock option plans assumed in connection with pooling of interests
business combinations are not presented prior to their acquisitions as the fair
value of the options and their related impact is immaterial.

     The fair value of shares issued under the employee stock purchase plans was
estimated as of the initial day of the purchase period using a Black-Scholes
option pricing model with the following weighted-average assumptions for 2000,
1999 and 1998: Risk free interest rates of 5.86%, 5.0% and 5.0%; volatility
factors of the expected market price of our common stock of 0.90, 0.84 and 0.75;
a weighted-average expected life of the purchase right of 0.5 years; and no
dividend yields. The weighted-average fair value of purchase rights granted
under the employee stock purchase plans during 2000, 1999, and 1998 were $27.60,
$2.82 and $2.30.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of publicly traded options that have no vesting
restrictions and are fully transferable. In addition, option valuation models
require the input of highly subjective assumptions including the expected stock
price volatility. Because our employee stock options have characteristics
significantly different from those of publicly traded options, and because
changes in the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options and employee stock purchase plans' shares.

     The following pro forma information presents net income (loss) and earnings
per share for 2000, 1999 and 1998 had the fair value method of SFAS 123 been
used to measure compensation cost for stock compensation plans. For purposes of
these pro forma disclosures, the estimated fair value of the options is
amortized to expense over the options' vesting period and the estimated fair
value of the employee stock purchase plans' shares is amortized to expense over
the purchase period. These amounts have not been reflected in our Consolidated
Statements of Operations (in thousands, except per share amounts):

     We consider the earnings of foreign subsidiaries to be permanently
reinvested outside the United States. Accordingly, no United States income tax
on these earnings has been provided. Aggregate unremitted earnings of foreign
subsidiaries, for which U.S. income taxes have not been provided, totaled $42.9
million and $25.3 million as of December 31, 2000 and 1999.

     At December 31, 2000 and 1999, we had $929.6 million and $56.5 million of

2002 through 2020 and are subject to certain annual limitations. The federal
research and development carryforwards expire in the years 2005 through 2020.
The foreign net operating loss carryforwards have no expiration date.

     As of December 31, 2000 and 1999, we had net deferred tax assets totaling
$356.5 million and $42.0 million. Realization of our deferred tax asset is
dependent upon the U.S. consolidated tax group of companies having sufficient
federal taxable income in future years to utilize our net operating loss
carryforwards before they expire from 2002 through 2020. In 2000, we recognized
a significant tax benefit from the exercise of stock options, which was
reflected as an increase to additional paid-in capital in our financial
statements. We believe it is unlikely a similar annual tax benefit of this
relative magnitude from stock option exercises will be realized in a future
year. Considering our current level of taxable income without a stock option tax
benefit of this magnitude, we believe it is more likely than not that the
deferred tax asset will be realized during the net operating loss carryforward
period. A reduction in our federal taxable income could cause a portion or all
of our net operating loss carryforwards to expire with a corresponding loss of
the related deferred tax asset.

     We paid income taxes of $2.7 million, $3.2 million and $5.9 million in
2000, 1999 and 1998.

     Management regularly evaluates the realizability of its deferred tax assets
given the nature of its operations and given the tax jurisdictions in which it
operates. We adjust our valuation allowance from time to time based on such
evaluations.

10. COMMITMENTS AND CONTINGENCIES

     We lease our office facilities and certain office equipment under operating
leases that expire at various dates through 2011. We have renewal options for
most of our operating leases. Total rent expense incurred during 2000, 1999 and
1998 was $56.4 million, $26.2 million and $9.3 million.

     Future minimum lease payments under all noncancellable operating leases as
of December 31, 2000 are as follows:

     On October 10, 2000, we settled a lawsuit filed by a former employee
alleging his right to exercise stock options granted to him in 1996 while he was
employed by us, prior to the initial public offering of our stock. The
settlement resulted in the recognition of a $22.4 million non-cash, pre-tax
charge during the third quarter of 2000. In a separate matter, an employee of a
company we acquired in 1998 is currently disputing the cancellation of stock
options received at the time of the acquisition. Vesting of these options was
dependent upon continued employment; however, the employment was terminated in
2000. We maintain the former employee was not entitled to unvested stock
options.

     We are subject to various other claims and legal actions arising in the
ordinary course of business. In the opinion of management, after consultation
with legal counsel, the ultimate disposition of these matters is not expected to
have a material effect on our business, financial condition or results of
operations.

11. SEGMENT INFORMATION AND INTERNATIONAL OPERATIONS

     We operate our business in one segment, value-chain solutions designed to
help enterprises optimize business processes both internally and among trading
partners. SFAS 131, "Disclosures About Segments of an Enterprise and Related
Information," establishes standards for the reporting information about
operating segments. Operating segments are defined as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in assessing performance.

     We market our software and services primarily through our worldwide sales
organization augmented by other service providers, including both domestic and
international e-business providers and systems consulting and integration firms.
Our chief operating decision maker evaluates resource allocation decisions and
our performance based on financial information, presented on a consolidated
basis, accompanied by disaggregated information by geographic regions. Sales to
our customers generally include products from some or all of our product suites.
We do not allocate revenues from such sales to individual product lines for
internal or general-purpose financial statements.

     Total assets related to our international operations accounted for $350.3
million, or 3.8% of total consolidated assets, as of December 31, 2000 and
$132.2 million, or 15.4% of total consolidated assets, as of December 31, 1999.

12. NEW ACCOUNTING STANDARDS

     On January 1, 2001, we adopted SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS 137 and SFAS 138. SFAS
133 requires all derivatives to be recorded at fair value. Unless designated as
hedges, changes in these fair values will be recorded in the income statement.
Fair value changes involving hedges will generally be recorded by offsetting
gains and losses on the hedge and on the hedged item, even if the fair value of
the hedged item is not otherwise recorded. Adoption of this standard did not
have a material effect on our financial statements.

     We address certain financial exposures through a controlled program of risk
management that includes the use of derivative financial instruments. We do not
utilize or expect to utilize derivative financial instruments for trading or
speculative purposes.

     During the periods presented, our strategy for managing foreign currency
risk was limited to hedging certain significant accounts receivable that were
denominated in foreign currency. In January 2001, we established a foreign
currency hedging program utilizing foreign currency forward contracts to hedge
various nonfunctional currency exposures with the objective of reducing the
effect of foreign currency exchange rates on our results of operations.

     In February 2001, the Financial Accounting Standards Board issued a
revision to a previously issued exposure draft covering business combinations
proposing new accounting guidance related to goodwill. This proposed standard
would not allow for amortization of goodwill. The carrying amount of goodwill
would be reduced only if it was found to be impaired. Goodwill would be tested
for impairment when events or circumstances occur indicating that goodwill might
be impaired. A fair-value based impairment test would be used to measure
goodwill for impairment in lieu of the method for measuring impairment of
long-lived assets set forth in SFAS 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." As goodwill is
measured as a residual amount in an acquisition, it is not possible to directly
measure the fair value of goodwill. Under this proposed standard, the net assets
of a reporting unit should be subtracted from the fair value of that reporting
unit to determine the implied fair value of goodwill. Impairment loss would be
recognized to the extent the carrying amount of goodwill exceeds the implied
fair value. The provisions of this proposed standard would be effective for
fiscal quarters beginning after the issuance of a final statement. Management
believes the adoption of this standard, as it is proposed, will have a material
impact on our financial statements if the final statement is issued prior to the
full amortization of our remaining goodwill.

13. SUBSEQUENT EVENTS

     Since March 2, 2001, several class action lawsuits have been filed in the
United States District Court, Northern District of Texas, Dallas Division,
alleging that we and certain of our officers have violated federal securities
laws. In substance, all of the complaints allege that we issued a series of
false and misleading statements which failed to disclose, among other things,
that we were experiencing software implementation difficulties with our customer
Nike, Inc. and that these problems were material, severe and damaging our
relationship with Nike. The plaintiffs in the actions purport to represent
persons who purchased our stock during various periods ranging from October 18,
2000 to February 26, 2001. As these suits have just been filed, we have not had
the opportunity to adequately review the claims or respond. Although the
ultimate outcome and liability, if any, cannot be determined, we believe the
facts in these class actions do not support the plaintiffs' claims and we and
our officers and directors have meritorious defenses.

     On March 8, 2001, we entered into a definitive agreement to acquire
RightWorks Corporation, a developer of software that is designed to enable
companies to manage procurement across multiple enterprises for both direct and
indirect materials, and support buying models, from negotiated procurements to
auctions. In connection with the acquisition, we will exchange approximately 5.3
million shares of our common stock for all the outstanding stock of RightWorks.
The transaction is expected to close in the third quarter of 2001 and will be
accounted for using the purchase method.

     On March 9, 2001, we announced a voluntary stock option exchange program
for the benefit of our employees. Under the program, our employees have the
option to cancel certain outstanding stock options previously granted to them
for new stock options to be granted no earlier than October 8, 2001. The new
options will be granted with a strike price to be set at the fair market value
of our stock at the date of grant. Employees will receive 1.1 new stock options
for each stock option cancelled. The exchange program has been organized to
comply with applicable accounting standards and, accordingly, no compensation
charges related to this program will result. Members of our Board of Directors,
executive officers, and certain members of the senior management team are not
eligible to participate in this program.
