INDUSTRY BACKGROUND
 
     Today's increasingly competitive business environment has forced many
companies to increase manufacturing efficiency while improving their 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 supply chain may span multiple
continents, tying suppliers in one part of the world with a plant in another to
serve customers in yet a third location. These forces are prompting companies to
work closely and collaborate with a broad range of suppliers and customers to
improve efficiencies across multi-enterprise supply chains. The growth of the
Internet and intranets is accelerating these changes by providing a ubiquitous,
platform-independent communications network. The combination of these forces has
created a dynamic, complex and highly interdependent business environment. In
response to these evolving market forces, many companies have
 
                                        1
<PAGE>   3
 
sought to reengineer their business processes to reduce manufacturing cycle
times, shift from mass-production to order-driven manufacturing, increase use of
outsourcing and share information with vendors and customers. The implementation
of software solutions to manage various elements of the supply chain has become
a key component of these reengineering initiatives. The Company believes that
companies are increasingly recognizing efficient supply chain management as a
critical source of competitive advantage in this rapidly changing business
environment.
 
THE TRADITIONAL APPROACH
 
     Companies have traditionally applied information technology to supply chain
management through Manufacturing Resource Planning ("MRP") systems, which
provide limited flexibility to accommodate rapidly changing business conditions
and customer requirements. In order to respond to an increasingly competitive
business environment and related complex supply chain issues, many companies
have adopted Enterprise Resource Planning ("ERP") systems, which integrate MRP
solutions with other enterprise management applications such as financial,
accounting and human resources. Although ERP systems provide substantial
benefits primarily by integrating financial and other controls with multi-plant
manufacturing coordination, the supply chain decision support capabilities of
many ERP systems remain limited by the planning and scheduling methodologies
utilized in their MRP modules. Various ERP vendors are mitigating these
limitations by internally developing, or by acquiring or partnering with
independent developers of, advanced planning and scheduling software.
 
     Some of the significant limitations of traditional MRP systems and the MRP
modules of ERP systems are as follows:
 
          LIMITED DECISION SUPPORT. Traditional solutions collect and report
     large amounts of transactional data, rather than provide sophisticated
     analysis of relevant information to support critical business decisions in
     real-time. While these solutions help customers unify disparate information
     resources within the enterprise and contribute to business process
     reengineering efforts, the Company believes that they are not well-suited
     to enable customers to make rapid, highly complex business decisions.
 
          LIMITED REPRESENTATION OF SUPPLY CHAIN. The Company believes that
     traditional solutions lack the flexibility and functionality needed to
     create a highly accurate model of the supply chain because they often
     employ fixed assumptions regarding critical operating constraints such as
     available production capacity and supplier lead times. Since this approach
     cannot adequately capture complex real-world constraints and
     interdependencies, it may result in the development of infeasible or
     suboptimal plans. In addition, traditional solutions calculate plans and
     schedules for individual, local segments of the production and supply
     process, without considering the consequences to the entire process. For
     example, an increase in customer demand might result in the purchase of
     additional raw materials without determining whether manufacturing capacity
     is available to process those materials. This approach incorrectly assumes
     that optimizing production for an individual step within the production
     process will lead to an optimal result for the manufacturing operation or
     supply chain as a whole.
 
          SEQUENTIAL PLANNING. Traditional planning methodologies model the
     supply chain as a sequence of discrete steps. For example, traditional
     solutions begin by developing a demand forecast from which a distribution
     plan is developed to determine the distribution center, warehouse or
     factory source which will be used to manufacture/distribute the products
     without regard to transportation or manufacturing constraints. A
     transportation plan is then generated to determine the optimal
     transportation methods to be used to ship the products without addressing
     the constraints of the remaining parts of the supply chain. A master
     production schedule is then generated which is used to develop a materials
     requirement plan, which in turn is used to arrive at a capacity
     requirements plan. Because the process does not address all constraints
     simultaneously, the initial planning cycle is rarely feasible or optimal.
     Moreover, as resources become constrained, sequential planning requires
     that the entire supply chain model be completely regenerated from the
     beginning to identify and resolve conflicts. As a result, the planning
     process often requires numerous manual iterations to develop a feasible
     solution. Once an initial plan has been developed, the time-consuming
     nature of sequential planning limits a manager's ability to rapidly
 
                                        2
<PAGE>   4
 
     evaluate subsequent changes, such as material shortages and revisions in
     customer orders. Accordingly, a manager's ability to respond to changes and
     to effect corrective action may be delayed.
 
          LIMITED INTEGRATION AND FUNCTIONALITY. Traditional solutions may
     provide selected supply chain planning modules, but generally do not
     provide integrated functionality across the entire supply chain, including
     demand forecasting, manufacturing planning, plant scheduling, distribution
     and transportation. For example, several ERP vendors have acquired planning
     products which address specific supply chain challenges, but fail to
     provide global visibility and optimization across the entire supply chain.
     In addition, traditional solutions often offer only limited functionality
     within these areas. For example, MRP and ERP systems often provide limited
     "available-to-promise" functionality by simply processing orders on a
     "first-come, first-served" basis, without considering other constraints or
     business objectives. Furthermore, traditional solutions typically assume
     complete independence of supply and demand. Often, however, the
     overabundance or scarcity of a certain product can directly or indirectly
     impact demand for that product and related products. Complex
     interrelationships and interdependencies are not adequately accounted for
     in traditional planning methodologies, leading to potentially inaccurate
     conclusions and recommendations.
 
          LENGTHY IMPLEMENTATION CYCLES. Due to the broad scope, complexity and
     associated re-engineering requirements of ERP systems, many companies have
     found the implementation of such systems to be costly and time consuming.
     Such factors often delay or limit the realization of benefits associated
     with the implementation of ERP systems.
 
THE i2 SOLUTION
 
     i2 is the leading provider of client/server-based decision support software
products for supply chain management and related applications. The Company's
RHYTHM products enable businesses to plan and schedule the principal elements of
the supply chain by simultaneously considering internal constraints, such as
manufacturing facility capacities, human resource availability, alternate cost
strategies and distribution requirements, and external constraints, such as
supplier lead times and customer requirements. RHYTHM utilizes object-oriented
technology to model specific characteristics of a customer's operations, and
focuses primarily on supply chain management functions such as raw materials
procurement, capacity planning, distribution requirements and due date
scheduling. RHYTHM also incorporates an advanced forecasting module which
provides the ability to view and manipulate multi-dimensional data and analyze
the causal relationships between customer demand and internal and external
events.
 
     RHYTHM is designed to help businesses increase throughput, reduce
inventory, decrease cycle times, improve customer delivery date performance and,
consequently, enhance return on assets. The Company's software products are also
designed to enable customers to reduce costs, increase market share and enhance
their competitive advantage. i2's approach to customer relationships is centered
on the identification of potential savings and the creation of value for
customers. As part of this dedication to providing value for customers, i2 has
established a goal of generating more than $50 billion in total value for its
customers by the year 2005 through growth and savings. Although RHYTHM is
usually deployed as a stand-alone alternative to MRP products, RHYTHM is often
implemented in conjunction with, or as a complement to, existing MRP and ERP
solutions. RHYTHM's data structures, methodologies and application logic
differentiate it from existing solutions in the following ways:
 
          DECISION SUPPORT. RHYTHM's memory-resident, object-oriented design
     allows for very rapid analysis and response to planning and scheduling
     issues. RHYTHM identifies production and scheduling problems as
     circumstances change, proposes optimal solutions and allows for automatic
     or manual corrective action. i2's software also allows managers to perform
     real-time simulations which gauge the impact of potential local actions on
     the supply chain. The Company believes that this decision support
     functionality enables customers to better manage complex supply chain
     issues in an effort to reduce costs, maximize throughput and improve return
     on assets.
 
          ACCURATE REPRESENTATION OF SUPPLY CHAIN. RHYTHM is designed to
     incorporate a broad range of specific, real-world constraints and thereby
     enhance the accuracy of the supply chain model and improve
 
                                        3
<PAGE>   5
 
     its decision-making utility. RHYTHM distinguishes between hard constraints,
     those which are not subject to change or flexibility (e.g., a machine's
     maximum rated production capacity), and soft constraints, those which may
     be altered in order to arrive at an optimal solution (e.g., preferred
     sources for materials). RHYTHM's incorporation of object-oriented data
     structures represents a significant advance in the creation of complex
     supply chain models.
 
          CONCURRENT PLANNING. In contrast to sequential planning, concurrent
     planning views all the steps in the manufacturing process simultaneously.
     Upon identification of a planning or scheduling change, RHYTHM immediately
     propagates the effect of the change upstream and downstream, from the point
     of origin, throughout the supply chain model to derive a revised, optimal
     solution. For example, an unforeseen loss of production capacity would
     automatically signal for a reduction in raw material procurement as well as
     the potential rescheduling of customer delivery dates. Because RHYTHM
     presents an integrated model of the supply chain, from demand forecasting
     to raw material procurement, work-in-process, distribution and
     transportation to customer delivery, it is able to provide solutions which
     optimize the efficiency of the supply chain as a whole rather than summing
     a series of local optimizations.
 
          GLOBAL INTEGRATION AND ADVANCED FUNCTIONALITY. RHYTHM provides
     customers with a fully integrated, end-to-end supply chain management
     solution, from demand forecasting to manufacturing planning, plant
     scheduling, distribution and transportation. This enables customers to
     address a broad range of supply chain issues and to gain visibility across
     their entire supply chains to identify, evaluate and address these issues
     rapidly and effectively. Additionally, RHYTHM analyzes complex
     supply/demand interrelationships in order to more accurately represent
     real-world supply chain mechanics. RHYTHM's architecture is designed to
     enable easy integration with a broad range of transactional, legacy and
     other decision support software programs, enabling customers to leverage
     their investments in these systems. RHYTHM also provides advanced
     functionality for its customers across the supply chain. For example,
     RHYTHM's available-to-promise functionality allows customers to commit to
     requested delivery dates based on a global view of materials, capacity and
     related business constraints, while considering a broad range of
     pre-defined user business objectives such as maximizing sales to higher
     profit margin customers rather than assimilating them on a "first-come,
     first-served" basis. In addition, the Company's multi-dimensional demand
     forecasting module allows users to forecast, plan and influence demand by
     evaluating more than 30 potential internal and external causal
     relationships.
 
          EASE OF IMPLEMENTATION. RHYTHM is designed as a broadly applicable
     software solution which is adaptable for customers in a wide range of
     industries. In addition, RHYTHM is designed to integrate easily with many
     existing client/server and legacy MRP and ERP systems. As a result,
     functional implementation at a single site can generally be completed
     within three to four months depending on the scope and complexity of the
     installation project. The Company's goal is for the customer to realize a
     significant return on its investment within a year of licensing.
 
STRATEGY
 
     The Company's objectives are to maintain its leadership position in
decision-support supply chain management software, help create significant value
for its customers and continue to increase its market share of the supply chain
management market. The Company's strategy for achieving these objectives is as
follows:
 
  EXPAND PRODUCT OFFERINGS
 
     i2 believes that it has gained significant experience in supply chain
management methodologies through its work with its existing customer base. The
Company intends to continue to leverage this experience, together with its
expertise in advanced software technology, to expand the scope of its supply
chain management software to more fully address certain components of the supply
chain. For example, the Company is currently developing additional functionality
for RHYTHM in the areas of transportation logistics. The Company is also
focusing on selected vertical markets such as Metals, Automotive, Consumer
Packaged Goods and other industries. Although the RHYTHM software is standard
across all industries, the Company is forming groups to identify and understand
the needs of particular industries. The Company is
 
                                        4
<PAGE>   6
 
leveraging the highly flexible nature of RHYTHM to develop a series of
preconfigured user interfaces tailored to address the requirements of such
specific industries.
 
  INVEST AGGRESSIVELY TO BUILD MARKET SHARE
 
     The Company has made and continues to make substantial investments to
expand its sales and marketing, research and development, consulting and
administrative infrastructure. i2 believes that such investments are necessary
to increase its market share and to capitalize on the growth opportunities in
the supply chain management software market.
 
  INTEROPERATE WITH A BROAD RANGE OF SOFTWARE PLATFORMS AND APPLICATIONS
 
     The Company believes that most larger companies operate in heterogeneous
computing environments, with diverse data repositories and transaction and
legacy systems. Therefore, the Company's software must be able to interact and
interoperate with a broad range of software platforms and products in order to
successfully manage complex, multi-enterprise supply chains. The Company's
strategy is to establish and maintain cooperative relationships with a broad
range of hardware and software vendors while maintaining platform-neutral
architecture. In this regard, the Company is working together with legacy and
ERP vendors such as SAP AG ("SAP"), Oracle Corporation ("Oracle"), Baan Company
N.V. ("Baan") and PeopleSoft, Inc. ("PeopleSoft") to establish and maintain the
necessary complex interfaces between the Company's software and such vendor's
transaction-based systems. In addition, the Company strives to balance its
relationships with platform and transaction system vendors to avoid becoming too
closely aligned with any individual vendor.
 
  FOCUS ON DEVELOPING COLLABORATIVE, MULTI-ENTERPRISE SOLUTIONS
 
     The Company has recently established a Global Decision Support
Architecture. This architecture has been designed to enable RHYTHM to easily
access data from a broad range of customer data repositories, enable smoother
communications and data translations between RHYTHM and disparate enterprise
software systems, provide a multi-dimensional, uniform user interface and enable
a greater level of collaborative planning across the supply chain. i2 believes
that customers must be able to integrate the variety of applications that they
use to run their business and that, over time, application integration and
collaborative, multi-enterprise planning will be critical to enable customers to
derive significant additional value from supply chain management.
 
  BUILD STRATEGIC ALLIANCES AND BROADEN DISTRIBUTION CHANNELS
 
     The Company intends to expand and seek additional strategic relationships
with MRP and ERP vendors to integrate RHYTHM with their software products to
create joint-marketing opportunities. In addition, the Company intends to
augment its sales efforts by establishing and expanding relationships with other
complementary business application software vendors and systems consulting and
integration firms. The Company is leveraging third-party implementation services
with large, international consulting firms such as Andersen Consulting, Deloitte
& Touche, Ernst & Young, KPMG Peat Marwick and Price Waterhouse to enable it to
more rapidly penetrate its target market. In addition, the Company has
established direct sales offices in international markets and intends to
continue to expand its United States and international sales forces.
 
  ACQUIRE COMPLEMENTARY BUSINESSES, PRODUCTS AND TECHNOLOGIES
 
     The Company believes that certain acquisitions will provide the opportunity
to broaden its product offerings and provide more comprehensive decision support
and supply chain management solutions. For example, the Company's acquisition in
May 1997 of Think Systems Corporation and Optimax Systems Corporation
significantly extended its capabilities in demand planning and manufacturing
scheduling. The Company may in the future pursue additional acquisitions of
businesses, products and technologies, or enter into joint venture arrangements,
which complement or expand its business.

PRODUCTS
 
     RHYTHM operates as a flexible, integrated supply chain management solution
and is available in single-site and multi-site configurations. RHYTHM is
currently composed of the following modules and extensions:
 
  MODULES
 
     SUPPLY CHAIN PLANNER(TM). Supply Chain Planner ("SCP") is the base product
required for all RHYTHM applications. It coordinates and optimizes all planning
and scheduling scenarios and holds the object framework. SCP contains the logic
common to all RHYTHM modules and extensions and provides the means to control
them concurrently.
 
     DEMAND PLANNER(TM). Demand Planner is used to forecast customer demand. It
uses many statistical techniques and multiple forecast approaches to anticipate
changes in demand, including changes as a result of promotions, advertising
campaigns, pricing policies or market perceptions.
 
     FACTORY PLANNER(TM). Factory Planner ("FP") is designed to perform
single-site planning. FP manages complex manufacturing operations involving
large numbers of resources and operational steps, and is engineered to solve
common factory planning problems such as managing complex bills of materials and
alternate routings. Through FP, users can input their manufacturing forecast,
desired levels of finished goods, back-orders and other demands or constraints,
set tolerances for changes in the levels of the manufacturing forecast and set
target inventory levels. Through an interactive user interface, FP allows the
user to reallocate materials, change quantities, expedite purchases, move
quantities and perform "what if" simulations under modified constraints to
produce a master production schedule.
 
     MASTER PLANNER(TM). Master Planner ("MP") integrates two or more Factory
Planner modules implemented at multiple sites. MP controls and enables
multi-site scheduling, sourcing, allocation and forecasting. MP facilitates the
development of an optimal solution for multi-site installations.
 
     ADVANCED SCHEDULER(TM). Advanced Scheduler ("AS") provides additional
scheduling functionality for plans produced by Factory Planner or Master
Planner. AS outputs a detailed schedule and sequencing plan which considers
set-up times, material availability and other user-defined constraints. AS'
planning algorithms include constraint-based routines to recommend sequencing of
work loads to optimize the user's key resources.
 
     SEQUENCER(TM). Sequencer is used to schedule assembly lines and other
sequential production facilities. Sequencer utilizes genetic algorithms to
optimize the sequence of orders through manufacturing operations to increase
throughput, balance workloads and achieve other optimization goals.
 
     DISTRIBUTION PLANNER(TM). Distribution Planner ("DP") integrates
manufacturing and distribution planning and scheduling. DP enables
implementation of automated allocation, sourcing and transportation solutions
and provides planners with the ability to manipulate distribution requirements
to achieve strategic customer service goals.
 
     TRANSPORTATION PLANNER(TM). Transportation Planner ("TP") determines the
most feasible plan of utilizing transportation resources to move inventory from
one location in the supply chain to another. TP allows users to consolidate
orders or shipments into loads, select the appropriate mode and carrier, as well
as schedule and route the loads in order to determine the most efficient method
of shipping inventory. TP is currently provided by a third-party software
provider.
 
  EXTENSIONS
 
     AVAILABLE-TO-PROMISE(TM). Available-to-Promise ("ATP") automatically
determines the quantity of goods deliverable by a requested date, as well as the
date upon which a complete order may be delivered based upon materials,
capacity, distribution capability, customer allocations, supplier allocations
and related business constraints. ATP is used to quote delivery dates to
customers on a real-time basis.

<PAGE>   8
 
     STRATEGY-DRIVEN PLANNER(TM). Strategy-Driven Planner ("SDP") allows users
to specify business rules on how RHYTHM will resolve problems found within the
supply chain. SDP incorporates "trade-off" logic which takes into account the
users' preferences regarding operational, financial and other measures.
 
     RHYTHMLINK(TM). RhythmLink facilitates communication and data exchange
between RHYTHM and other applications such as databases, report writers and ERP
solutions by using industry accepted standard technologies and interfaces.
RhythmLink is designed to enable companies to rapidly integrate and implement
the RHYTHM products with its existing information resources.
 
     All of the Company's products are currently available in English and many
of the products are available in German, French, Japanese and Spanish.
 
     During the last twelve months, the sales prices for RHYTHM software
packages, other than for three significantly large sales, generally ranged from
approximately $100,000 to approximately $5.5 million. The price for an
individual RHYTHM product package is determined based upon a number of factors,
including the RHYTHM modules and extensions purchased, the number of servers,
users and sites in the customer's system, as well as the complexity of the
customer's supply chain.
 
     RHYTHM is a client/server solution which can operate on hardware platforms
from Digital Equipment, Hewlett-Packard, IBM and Sun Microsystems using
Microsoft's Windows NT operating system or the UNIX variant supported by each
hardware platform. RHYTHM is written in C++ language and utilizes a fully
object-oriented data structure for representing operations, resources and
constraints in supply chains. Once a model is defined, the entire representation
is loaded into random access memory ("RAM") and all processing by RHYTHM takes
place in RAM. A typical supply chain model implemented in the Company's system
may occupy as much as two gigabytes of RAM. RHYTHM reads and writes data to a
wide variety of databases and data structures, and is operable in conjunction
with a wide variety of ERP systems. The Company believes that the combination of
its object-oriented and memory-resident technologies permit RHYTHM to achieve
accuracy and speed advantages over traditional planning and scheduling
solutions.
 
PRODUCT DEVELOPMENT
 
     The Company originally introduced its RHYTHM software in 1992 and has
subsequently released a number of product enhancements as well as acquired
significant products. The Company has adopted a strategy of periodically
reinventing its products in order to meet its customers' needs, and strives to
ensure that each new generation of RHYTHM is compatible with previous releases.
On-going product development efforts are focused on broadening the functionality
of RHYTHM to more fully address certain areas of supply chain management,
including transportation logistics. The Company also licenses certain
third-party software including an advanced transportation module.
 
     In October 1997, the Company announced several products in various stages
of development, each of which is designed for multi-enterprise supply chain
collaboration. Within this broader line of products under development, the
Company has released a decision support architecture that will enable customers
to implement comprehensive planning and decision support solutions that exchange
information in diverse environments regardless of data structures and platforms
employed. The Company also has released a product which will provide a single
graphical model of an organization's entire supply chain and present a real-time
view of the performance of individual elements of the supply chain as well as
the supply chain as a whole. There can be no assurance that the Company will be
successful in further developing these or any other new products, that the
Company will not experience difficulties that could delay or prevent successful
development, introduction and sales of these products, or that its new products
and enhancements will adequately meet the requirements of the marketplace and
achieve market acceptance.
 
     RHYTHM products have been developed by the Company's internal developmental
staff through small project teams focused on independent components of the
software under development. The Company maintains product release planning
procedures to ensure integration, testing and version control among the
different project development teams. The Company operates its research and
development department in a "technology neutral" environment which makes it
possible to operate within industry standards and yet be
 
                                        7
<PAGE>   9
 
independent of particular database formats, hardware platforms, network
protocols and interfaces. The Company maintains significant development centers
in Bangalore and Mumbai, India; Cambridge, Massachusetts; Dallas, Texas;
Parsippany, New Jersey; and Toronto, Ontario.
 
     Research and development expenses have increased significantly in recent
periods as the Company has continued to focus on development of new and enhanced
products. Research and development expenses were $5.5 million, $17.0 million and
$44.1 million in 1995, 1996 and 1997, representing 18.0%, 19.3% and 22.0% of
total revenues, respectively. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Results of Operations -- Costs
and Expenses -- Research and Development" in Item 7 of this Form 10-K.
 
CUSTOMER SERVICE AND SUPPORT
 
     The Company believes that providing a high level of customer service and
technical support is necessary to achieve rapid product implementation which, in
turn, is essential to customer satisfaction and continued license sales and
revenue growth. During 1996 and 1997, the Company expanded its service and
support centers geographically and now has support centers across the United
States and in Australia, Belgium, Canada, Denmark, France, Germany, India,
Japan, Mexico, Singapore and the United Kingdom. Accordingly, the Company is
committed to continue recruiting and maintaining a high-quality technical
support team. The Company's customer service and support activities consist of
the following:
 
  TRAINING
 
     The Company offers an intensive education and training program for its
customers and its third-party implementation providers. Classes are offered at
in-house facilities at certain of the Company's offices and at customer
locations. These classes focus on supply chain management principles as well as
the implementation and use of RHYTHM products.
 
  CONSULTING
 
     The Company offers its customers on-site consulting services aimed at
assisting in the implementation of RHYTHM and integration with the customers'
existing systems. The Company receives hourly fees for these services. 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. The Company also leverages the use of third-party consulting
firms to more rapidly penetrate its target market.
 
  MAINTENANCE AND PRODUCT UPDATES
 
     The Company provides ongoing product support services under its license
agreements. Maintenance contracts are typically sold to customers for a one-year
term at the time of the initial RHYTHM license and may be renewed for additional
periods. Under its maintenance agreements with its customers, the Company
provides, without additional charge, product updates and enhancements to the
RHYTHM products previously purchased by the customer. Customers that do not
renew their maintenance agreements but wish to obtain product updates and new
version releases are generally required to purchase such items from the Company
at market prices. Ongoing support and maintenance services are provided on up to
a seven-day week, 24-hour day basis.
 
SALES AND MARKETING
 
     The Company markets its software and services primarily through its direct
sales organization augmented by other sales channels, including business
application software vendors and systems consulting and integration firms. At
December 31, 1997, the Company conducted sales and other activities through
several offices in the United States and additional offices in Australia,
Belgium, Brazil, Canada, Denmark, France, Germany, Italy, Japan, Korea,
Singapore and the United Kingdom. The Company's direct sales organization
consists of regionally based sales representatives and sales engineers supported
by personnel with experience in
 
                                        8
<PAGE>   10
 
the aerospace, apparel, automotive, consumer products, furniture, high-tech,
industrial, metals, paper, pharmaceuticals, process, retail and textiles
industries.
 
     The Company currently has joint-marketing agreements with a number of
business application software vendors, including SAP and System Software
Associates, Inc. ("SSA"), and several systems consulting and integration firms.
These joint-marketing agreements generally provide the vendors with
non-exclusive rights to market RHYTHM products and access to marketing materials
and product training. Furthermore, the vendors receive a specified commission
for license revenues generated by the vendor during the term of the agreement,
which commissions vary from zero to 40% of the sales price of the license. In
addition, the Company and Oracle recently entered into a development and
distribution agreement pursuant to which the parties will jointly develop an
enhanced interface between RHYTHM and Oracle's enterprise resource planning
solutions. Under this agreement, the Company also granted to Oracle a
non-exclusive right to sublicense i2's RHYTHM products to end users as standard
Oracle applications. By using these indirect sales channels, the Company is
seeking to capitalize on the installed base of other software vendors and obtain
favorable product recommendations from systems consulting and integration firms,
thereby increasing RHYTHM's market coverage. There can be no assurance that any
of these joint-marketing and development agreements will be beneficial to the
Company or that such relationships will be sustained.
 
CUSTOMERS
 
     As of December 31, 1997, the Company had licensed RHYTHM products to
approximately 220 customers. The following is a partial list of companies that
have licensed more than $750,000 of RHYTHM products since December 31, 1994:

</TABLE>
 
     The Company provides its software products to customers under
non-exclusive, non-transferable license agreements. As is customary in the
software industry, in order to protect its intellectual property rights, the
Company does not sell or transfer title to its products to its customers. Under
the Company's current standard form of license agreement, licensed software may
be used solely for the customer's internal operations.

COMPETITION
 
     The markets in which the Company operates are highly competitive. The
Company's competitors are diverse and offer a variety of solutions directed at
various segments of the supply chain as well as the enterprise as a whole.
Competitors include: (i) enterprise resource application software vendors such
as SAP, PeopleSoft, Oracle and Baan, each of which currently offers
sophisticated ERP solutions that currently or may in the future incorporate
supply chain management modules or advanced planning and scheduling software;
(ii) other suppliers of supply chain software including Manugistics Group, Inc.
and Logility, Inc.; (iii) other business application software vendors who may
broaden their product offerings by internally developing, or by acquiring or
partnering with independent developers of, advanced planning and scheduling
software; (iv) internal development efforts by corporate information technology
departments; and (v) companies offering standardized or customized products for
mainframe and/or mid-range computer systems.
 
     In connection with specific customer solicitations, a number of ERP vendors
have from time to time jointly marketed the Company's products as a complement
to their own systems. The Company believes that as its market share increases,
and as the ranges of products offered by the Company and these ERP vendors
expand and increasingly overlap, relationships which were cooperative in the
past will become more competitive, thereby increasing the overall level of
competition the Company faces. Specifically, the Company and SAP recently
terminated a license and distribution agreement, and SAP has announced its
intention to develop a suite of advanced planning and scheduling products which
are expected to be directly competitive with RHYTHM. The Company believes that
additional ERP vendors are focusing significant resources on increasing the
functionality of their own planning and scheduling modules, and at least two ERP
vendors have recently acquired independent developers of advanced planning and
scheduling software which compete with RHYTHM.
 
     Many of the Company's competitors have longer operating histories,
significantly greater financial, technical, marketing and other resources,
greater name recognition, a broader range of products to offer and a larger
installed base of customers than the Company, each of which could provide them
with a significant competitive advantage over the Company. In addition, the
Company expects to experience increasing price competition as the Company and
its competitors compete for market share. There can be no assurance that the
Company will be able to compete successfully with existing or new competitors or
that competition will not have a material adverse effect on the Company's
business, operating results and financial condition.
 
PROPRIETARY RIGHTS AND LICENSES
 
     The Company relies primarily on a combination of copyright, trademark and
trade secret laws, confidentiality procedures and contractual provisions to
protect its proprietary rights. In addition, the Company generally licenses
RHYTHM products to end users in object code (machine-readable) format, and the
Company's license agreements generally allow the use of RHYTHM products solely
by the customer for internal purposes without the right to sublicense or
transfer the RHYTHM products. However, the Company believes that the foregoing
measures afford only limited protection. Despite the Company's efforts to
protect its proprietary rights, unauthorized parties may attempt to copy aspects
of the Company's products or to obtain and use information that the Company
regards as proprietary. Policing unauthorized use of the Company's products is
difficult, and while the Company is unable to determine the extent to which
piracy of its software products exist, software piracy can be expected to be a
problem. In addition, the laws of some foreign countries do not protect the
Company's proprietary rights to the same extent as the laws of the United
States. Furthermore, there can be no assurance that the Company's competitors
will not independently develop technology similar to that of the Company. The
Company may increasingly be subject to claims of intellectual property
infringement as the number of products and competitors in the Company's industry
segment grows and the functionality of products in different industry segments
overlaps. Although the Company is not aware that any of its products infringes
upon the proprietary rights of third parties, there can be no assurance that
third parties will not claim infringement by the Company with respect to current
or future products. Any such claims, with or without merit, could be
time-consuming, result in costly litigation, cause product shipment delays or
require the Company to enter into royalty or licensing agreements. Such royalty
or
 
                                       10
<PAGE>   12
 
licensing agreements, if required, may not be available on terms acceptable to
the Company, which could have a material adverse effect upon the Company's
business, operating results and financial condition.
 
     The Company has in the past and may in the future resell certain software
which it licenses from third parties. There can be no assurance that these
third-party software licenses will continue to be available to the Company on
commercially reasonable terms. The loss of or inability to maintain or obtain
any of these software licenses could result in delays or reductions in product
shipments until equivalent software could be identified, licensed and
integrated, which could adversely affect the Company's business, operating
results and financial condition.
 
EMPLOYEES
 
     As of December 31, 1997, the Company had 1,006 full-time employees,
including 397 primarily engaged in research and development activities and 258
engaged in sales and marketing activities. The Company's future success depends
in significant part upon the continued service of its key technical and senior
management personnel and its continuing ability to attract and retain highly
qualified technical and managerial personnel. Competition for such personnel is
intense and there can be no assurance that the Company can retain its key
managerial and technical employees or that it can attract, assimilate or retain
other highly qualified technical and managerial personnel in the future. None of
the Company's employees are represented by collective bargaining units and the
Company has never experienced a work stoppage. The Company believes that its
employee relations are very good.
 
ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     In addition to the other information in this Form 10-K, the following
factors should be considered in evaluating the Company and its business.
 
  POTENTIAL FOR SIGNIFICANT FLUCTUATIONS IN QUARTERLY RESULTS; DEPENDENCE ON
SIGNIFICANT INDIVIDUAL SALES
 
     The Company's quarterly revenues, expenses and operating results have
varied significantly in the past and are likely to vary significantly from
quarter to quarter in the future. Because the purchase of a supply chain
management software solution generally involves a significant commitment of
capital, the sales cycle associated with the purchase of the Company's products
varies substantially and is subject to a number of significant risks, including
customers' budgetary constraints, timing of budget cycles and concerns about the
pricing or introduction of new products by the Company or its competitors,
factors over which the Company has little or no control. Additional factors
include foreign currency exchange rate fluctuations, the mix of direct or
indirect sales, changes in joint-marketing relationships, and changes in the
Company's strategy. Furthermore, purchases of the Company's products may be
deferred or canceled in the event of a downturn in any potential customer's
business or the economy in general.
 
     The amount of revenues associated with particular licenses can vary
significantly based upon the number of software modules purchased and the number
of sites and users involved in the installation. The Company generally derives a
significant portion of its software license revenues in each quarter from a
small number of relatively large sales. For example, in each quarter of 1996 and
1997, one or more customers each accounted for at least 15% of total software
license revenues in such quarter. While the Company believes that the loss of
any of these particular customers would not have an adverse effect, an inability
to consummate one or more substantial license sales in any future period could
have a material adverse effect on the Company's operating results for that
period. Moreover, similar to many other software companies, the Company
typically realizes a significant portion of its software license revenues in the
last month or even the last week of a quarter. The Company also believes that
the tendency of customers to delay placing orders for software products until
near the end of a quarter has become more pronounced in recent periods. As a
result, small delays in customer orders can cause significant variability in the
Company's license revenues and results of operations for any particular period.
For all of the foregoing reasons, revenues are difficult to forecast.
 
     The Company intends to continue to invest heavily in its sales and
marketing, consulting and research and development organizations, and sets
investment and expense levels based on expected future revenues. If
                                       11
<PAGE>   13
 
revenues are below expectations, operating results and net income are likely to
be adversely and disproportionately affected because a significant portion of
the Company's expenses are not variable in the short term, and cannot be quickly
reduced to respond to decreases in revenues. In addition, the Company may reduce
prices or accelerate its investment in research and development efforts in
response to competition or to pursue new market opportunities. Any one of these
activities may further limit the Company's ability to adjust spending in
response to fluctuations in revenue levels. There can be no assurance that
revenues will grow in future periods, that they will grow at historical rates,
or that the Company will maintain positive operating margins in future quarters.
 
     The Company's quarterly results of operations are subject to certain
seasonal fluctuations. Historically, the Company's revenues have tended to be
strongest in the fourth quarter of the year and to increase only modestly in the
first quarter of the following year. The Company believes that this seasonality
is due to the calendar year budgeting cycles of many of its customers and to
compensation policies that tend to compensate sales personnel for achieving
annual revenue quotas. The Company expects that in future periods these seasonal
trends may cause first quarter revenues to remain consistent with, or decrease
from, the level achieved in the preceding quarter.
 
  MANAGEMENT OF GROWTH
 
     The Company's business has grown rapidly in recent years, with revenues
increasing from $30.5 million in 1995 to $87.9 million in 1996 and to $200.7
million in 1997. The Company's recent expansion has resulted in substantial
growth in the number of its employees (from 260 at December 31, 1995 to 582 at
December 31, 1996 to 1,006 at December 31, 1997), the scope of its operating and
financial systems and the geographic distribution of its operations and
customers. This recent rapid growth has placed, and if continued will continue
to place, a significant strain on the Company's management and operations.
Accordingly, the Company's future operating results will depend on the ability
of its officers and other key employees to continue to implement and improve its
operational, customer support and financial control systems, and to effectively
expand, train and manage its employee base. There can be no assurance that the
Company will be able to manage any future expansion successfully, and any
inability to do so would have a material adverse effect on the Company's
business, operating results and financial condition.
 
  PRODUCT CONCENTRATION; DEPENDENCE ON PRODUCT LINE EXPANSION
 
     The Company currently derives all of its revenues from RHYTHM licenses and
related services. The Company expects that RHYTHM-related revenues, including
maintenance and consulting contracts, will continue to account for substantially
all of the Company's revenues for the foreseeable future. As a result, the
Company's future operating results are dependent upon continued market
acceptance of RHYTHM and enhancements thereto. There can be no assurance that
RHYTHM will achieve continued market acceptance. A decline in demand for, or
market acceptance of, RHYTHM as a result of competition, technological change or
other factors would have a material adverse effect on the Company's business,
operating results and financial condition.
 
     As enterprises increasingly focus on decision support for supply chain
management challenges, they are requiring greater levels of functionality and
broader product offerings from their application software vendors. Moreover, the
market for the Company's software products is characterized by rapid
technological advances, evolving industry standards in computer hardware and
software technology, and frequent product introductions and enhancements. The
Company's future success will depend upon its ability to continue to enhance its
current product line and to develop and introduce new products that keep pace
with technological developments, satisfy increasingly sophisticated customer
requirements and achieve market acceptance. There can be no assurance that the
Company will be successful in developing and marketing, on a timely and cost-
effective basis, fully functional product enhancements or new products that
respond to technological advances by others, or that its new products will
achieve market acceptance. The Company's failure to successfully develop and
market product enhancements or new products could have a material adverse effect
on the Company's business, operating results and financial condition.
 
                                       12
<PAGE>   14
 
  INTEGRATION OF RECENT ACQUISITIONS; POTENTIAL FUTURE ACQUISITIONS
 
     In April 1997, the Company completed the acquisition of the Operations
Planning Group ("OPG"), a business activity of Computer Sciences Corporation. In
May 1997, the Company acquired Think Systems Corporation, a New Jersey
corporation ("Think"), and Optimax Systems Corporation, a Delaware corporation
("Optimax"). In November 1997, the Company acquired the remaining interest in a
minority owned subsidiary, M-Star Systems Limited ("M-Star"). The success of
acquisitions depends primarily on the Company's ability to (i) retain, motivate
and integrate the acquired personnel with the Company's operations, (ii)
integrate multiple information systems and (iii) integrate acquired software
with RHYTHM. No assurance can be given that the Company will not encounter
difficulties in integrating the respective operations and products of the
Company, OPG, Think, Optimax and M-Star or that the benefits expected from such
integration will be realized. Failure to successfully integrate OPG's, Think's,
Optimax's and M-Star's respective operations and products into the Company's
operations and products could have a material adverse effect on the Company's
business, operating results and financial condition.
 
     The Company may in the future pursue additional acquisitions of businesses,
products and technologies, or enter into joint venture arrangements, that could
complement or expand the Company's business. The negotiation of potential
acquisitions or joint ventures as well as the integration of an acquired
business, product or technology could cause diversion of management's time and
resources. Future acquisitions by the Company could result in potentially
dilutive issuances of equity securities, the incurrence of debt and contingent
liabilities, amortization of goodwill and other intangibles, research and
development write-offs and other acquisition-related expenses. Further, no
assurances can be given that any acquired business will be successfully
integrated with the Company's operations. If any such acquisition were to occur,
there can be no assurance that the Company will receive the intended benefits of
the acquisition. Future acquisitions, whether or not consummated, could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
  INTERNATIONAL OPERATIONS AND CURRENCY FLUCTUATIONS
 
     The Company derived approximately 7%, 23% and 33% of its total revenues
from customers located outside of the United States in 1995, 1996 and 1997,
respectively. The Company believes that continued growth and profitability will
require expansion of its sales in international markets. Further penetration of
international markets will require the Company to expand existing foreign
operations, to establish additional foreign operations and to translate its
software and manuals into additional foreign languages. This expansion may be
costly and time-consuming and may not generate returns for a significant period
of time, if at all. To the extent that the Company is unable to expand its
international operations or translate its software and manuals into foreign
languages in a timely manner, the Company's ability to further penetrate
international markets would be adversely affected, which could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
     The Company's international operations are subject to risks inherent in
international business activities, including: difficulty in staffing and
managing geographically disparate operations; longer accounts receivable payment
cycles in certain countries; compliance with a variety of foreign laws and
regulations; unexpected changes in regulatory requirements; overlap of different
tax structures; greater difficulty in safeguarding intellectual property; import
and export licensing requirements; trade restrictions; changes in tariff rates;
and general economic conditions in international markets. In particular,
countries in the Asia Pacific region have recently experienced weaknesses in
their currency, banking and equity markets. In the future, these weaknesses
could adversely affect the demand for the Company's products, the U.S. dollar
value of the Company's foreign currency denominated sales and ultimately the
Company's results of operations. There can be no assurance that the Company's
business, results of operations or financial condition will not be adversely
affected by these or other factors that may affect international operations.
 
     To date, the Company's revenues from international operations have
primarily been denominated in United States dollars. As a result, the Company's
sales in international markets may be adversely affected by a strengthening
United States dollar. Certain sales and the majority of the expenses incurred by
the Company's
 
                                       13
<PAGE>   15
 
international operations are denominated in currencies other than the United
States dollar. In addition, with the expansion of international operations, the
number of foreign currencies in which the Company must operate will increase,
resulting in increased exposure to exchange rate fluctuations. The Company has
implemented limited hedging programs to mitigate its exposure to currency
fluctuations. Notwithstanding these hedging programs, exchange rate fluctuations
have caused and will continue to cause currency transaction gains and losses.
While such currency transaction gains and losses have not been material to date,
there can be no assurance that currency transaction losses will not have a
material adverse effect on the Company's business, results of operations or
financial condition in future periods.
 
  RISKS ASSOCIATED WITH STRATEGIC RELATIONSHIPS
 
     The Company has from time to time established relationships with other
companies, including Oracle and SSA, involving collaboration in areas such as
product development, marketing, distribution and implementation. The maintenance
of these relationships and the development of other such relationships is a
meaningful part of the Company's business strategy. However, most of the
Company's current and potential strategic partners are either potential
competitors of the Company or are currently competitive with the Company to some
degree. In addition, certain of the Company's cooperative relationships have
failed to meet expectations, such as the Company's terminated license and
distribution relationship with SAP. There can be no assurance that the Company's
current collaborative relationships will be beneficial to the Company, that such
relationships will be sustained, or that the Company will be able to enter into
successful new strategic relationships in the future.
 
  DEPENDENCE UPON KEY PERSONNEL
 
     The Company's future operating results depend in significant part upon the
continued service of a relatively small number of key technical and senior
management personnel, few of whom are bound by an employment agreement. The
Company's future success also depends on its continuing ability to attract,
train and retain other highly qualified technical and managerial personnel.
Competition for such personnel is intense, and the Company has at times in the
past experienced difficulty in recruiting qualified personnel. There can be no
assurance that the Company will retain its key technical and managerial
employees or that it will be successful in attracting, assimilating and
retaining other highly qualified technical and managerial personnel in the
future. Kanna (Ken) N. Sharma, the Company's Vice Chairman of the Board and
Executive Vice President, has recently been diagnosed with a brain tumor. While
Mr. Sharma is currently providing services to the Company, there can be no
assurance as to how long he will be able to continue to do so. The loss of any
member of the Company's key technical and senior management personnel or the
inability to attract and retain additional qualified personnel could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
  COMPLEXITY OF SOFTWARE PRODUCTS; RAPID TECHNOLOGICAL CHANGE AND NEW PRODUCTS
 
     RHYTHM is a client/server solution which can operate on hardware platforms
from Digital Equipment, Hewlett-Packard, IBM and Sun Microsystems and operating
systems from Sun Microsystems and Microsoft, and can access data from most
widely used SQL (structured query language) databases, including Informix,
Oracle and Sybase. To the extent that additional hardware or software platforms
gain significant market acceptance, the Company may be required to port RHYTHM
to such platforms in order to remain competitive. Such platforms may not be
architecturally compatible with RHYTHM's software product design, and there can
be no assurance that the Company will be able to port RHYTHM to such additional
platforms on a timely basis or at all. Any failure to maintain compatibility
with existing platforms or to port to new platforms that achieve significant
market acceptance would have a material adverse effect on the Company's
business, operating results and financial condition.
 
     As a result of the complexities inherent in client/server computing
environments and the broad functionality and performance demanded by customers
for supply chain management products, major new products and product
enhancements can require long development and testing periods. In addition,
software programs as complex as those offered by the Company may contain
undetected errors or "bugs" when first
                                       14
<PAGE>   16
 
introduced or as new versions are released that, despite testing by the Company,
are discovered only after a product has been installed and used by customers.
While the Company has on occasion experienced delays in the scheduled
introduction of new and enhanced products and products containing bugs, to date
the Company's business has not been materially adversely affected by delays or
the release of products containing errors. There can be no assurance, however,
that errors will not be found in future releases of the Company's software, or
that any such errors will not impair the market acceptance of these products and
adversely affect the Company's business, operating results and financial
condition.
 
     While the Company generally takes steps to avoid interruptions of sales
often associated with the pending availability of new products, customers may
delay their purchasing decisions in anticipation of the general availability of
new or enhanced RHYTHM products, which could have a material adverse effect on
the Company's business and operating results. Moreover, significant delays in
the general availability of such new releases, significant problems in the
installation or implementation of such new releases, or customer dissatisfaction
with such new releases, could have a material adverse effect on the Company's
business, operating results and financial condition.
 
  DEPENDENCE ON TECHNICAL AND IMPLEMENTATION PERSONNEL
 
     The sales of RHYTHM typically involve the utilization of highly qualified
technical sales support personnel. A limitation on the number of qualified
technical sales support personnel could have a material adverse effect on the
Company's ability to expand sales and enter into new vertical markets. The
implementation of RHYTHM requires the services of highly trained implementation
personnel working directly for the Company or for independent consultants. A
shortage in the number of trained implementers, either within the Company or
with third-party consulting firms, could limit the Company's ability to
implement its software on a timely and effective basis. Delayed or ineffective
implementation of the Company's software may limit the Company's ability to
expand its revenues and may result in customer dissatisfaction and damage the
Company's reputation, each of which could have a material adverse effect on the
Company's business, operating results and financial condition.
 
  YEAR 2000 COMPLIANCE
 
     Many older computer systems and software products currently in use are
coded to accept only two digit entries in the date code field. These date code
fields will need to accept four digit entries to distinguish 21st century dates
from 20th century dates. As a result, in less than two years, computer systems
and/or software used by many companies may need to be upgraded to comply with
such "Year 2000" requirements. Significant uncertainty exists in the software
industry concerning the potential effects associated with such compliance.
Although the Company currently offers software products that are designed to be
Year 2000 compliant, Year 2000 problems inherent in a customer's transactional
software programs might significantly limit that customer's ability to realize
the intended benefits offered by RHYTHM.
 
     The Company believes that the purchasing patterns of customers and
potential customers may be affected by Year 2000 issues in a variety of ways.
Many companies are expending significant resources to correct or patch their
current hardware and software systems for Year 2000 compliance. These
expenditures may result in reduced funds available to purchase software products
such as those offered by the Company. Any of the foregoing could result in a
material adverse effect on the Company's business, operating results and
financial condition.
 
     The Company utilizes third-party vendor equipment, telecommunication
products and software products which may or may not be Year 2000 compliant.
Although the Company is currently taking steps to address the impact, if any, of
the Year 2000 compliance issue surrounding such third-party products, failure of
any critical technology components to be Year 2000 compliant may have an adverse
impact on business operations or require the Company to incur unanticipated
expenses to remedy any problems.
 
                                       15
<PAGE>   17
 
  PRODUCT LIABILITY
 
     While the Company's license agreements with its customers typically contain
provisions designed to limit the Company's exposure to potential product
liability claims, it is possible that such limitation of liability provisions
may not be effective under the laws of certain jurisdictions. Although the
Company has not experienced any product liability claims to date, there can be
no assurance that the Company will not be subject to such claims in the future.
A successful product liability claim brought against the Company could have a
material adverse effect on the Company's business, operating results and
financial condition. Moreover, defending such a suit, regardless of its merits,
could entail substantial expense and require the time and attention of key
management personnel, either of which could have a material adverse effect on
the Company's business, operating results and financial condition.
 
  VOLATILITY OF STOCK PRICE
 
     The market price of the Common Stock has been volatile at times and in the
future can be expected to be significantly affected by factors such as quarterly
variations in the Company's results of operations, the announcement of new
products or product enhancements by the Company or its competitors,
technological innovations by the Company or its competitors, and general market
conditions or market conditions specific to particular industries. In
particular, the stock prices for many companies in the technology and emerging
growth sectors have experienced wide fluctuations which have often been
unrelated to the operating performance of such companies. Such fluctuations may
adversely affect the market price of the Common Stock.
 
  CONTROL BY MANAGEMENT
 
     As of December 31, 1997, the Company's executive officers beneficially
owned approximately 58.3% of the Company's outstanding Common Stock.
Consequently, the Company's executive officers are able to control the outcome
of all matters submitted for stockholder action, including the election of
members to the Company's Board of Directors and the approval of significant
change in control transactions, and effectively control the management and
affairs of the Company, which may have the effect of delaying or preventing a
change in control of the Company. In addition, Messrs. Sanjiv S. Sidhu, Chairman
of the Board and Chief Executive Officer, Kanna (Ken) N. Sharma, Vice Chairman
of the Board, Executive Vice President and Secretary and Sandeep (Sandy) R.
Tungare, President, Demand Management, constitute three of the five members of
the Board of Directors and, therefore, have significant influence in directing
the actions of the Board of Directors.
 
  ANTI-TAKEOVER PROVISIONS
 
     The Company's Certificate of Incorporation, as amended (the "Charter"), and
Bylaws, as amended (the "Bylaws"), contain certain provisions that may have the
effect of discouraging, delaying or preventing a change in control of the
Company or unsolicited acquisition proposals that a stockholder might consider
favorable, including provisions: authorizing the issuance of "blank check"
preferred stock; providing for a Board of Directors with staggered, three-year
terms; requiring super-majority voting to effect certain amendments to the
Charter and Bylaws; limiting the persons who may call special meetings of
stockholders; prohibiting stockholder action by written consent; and
establishing advance notice requirements for nominations for election to the
Board of Directors or for proposing matters that can be acted upon at
stockholder meetings. Certain provisions of Delaware law and the Company's stock
incentive plans may also have the effect of discouraging, delaying or preventing
a change in control of the Company or unsolicited acquisition proposals.
 
ITEM 2. PROPERTIES
 
     The Company's primary offices are located in approximately 91,000 square
feet of space in Irving, Texas and approximately 23,000 square feet in Dallas,
Texas under leases expiring in October 2000 and December 1998, respectively. The
Company also leases space for its other offices in the United States, Australia,

     As of February 27, 1998, there were 32,690,164 shares of the Common Stock
outstanding held by 394 stockholders of record. The Company believes there are
approximately 4,000 beneficial owners of the Common Stock.
 
     The Company has never declared or paid cash dividends on its capital stock.
The Company currently intends to retain any earnings for use in its business and
does not anticipate paying any cash dividends in the foreseeable future. Future
dividends, if any, will be determined by the Company's Board of Directors.
 
     During 1997, the Company issued an aggregate 890,260 shares of its Common
Stock to employees pursuant to exercises of stock options (with exercise prices
ranging from $0.0175 to $12.11 per share) under the Company's 1992 Stock Plan
and 1995 Stock Option/Stock Issuance Plan which 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.

(1)  During 1997, the Company incurred approximately $9.3 million in certain
     acquisition-related expenses in connection with the business combinations
     involving Optimax Systems Corporation, Think Systems Corporation, the
     Operations Planning Group of Computer Sciences Corporation and M-Star
     Systems Limited, of which $4.6 million represents the write-off of
     in-process research and development. The remaining costs include, among
     other things, investment banking, legal and accounting fees and expenses.
     The acquisition-related expenses resulted in a one-time charge to the
     Company's operating results.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS
 
OVERVIEW
 
     The Company is the leading provider of client/server-based decision support
software products for supply chain management and related applications. The
Company also provides services such as consulting, training and maintenance
related to these products. Supply chain management encompasses the planning and
scheduling of manufacturing and related logistics, including demand forecasting,
raw materials procurement, work-in-process, distribution and transportation
across multiple enterprises. i2's client/server software solution, RHYTHM, is
designed to provide customers with an end-to-end supply chain management
solution, enabling customers to model complex, multi-enterprise supply chains to
rapidly generate integrated solutions to supply chain challenges such as demand
volatility, production bottlenecks, supply interruptions and distribution
alternatives. RHYTHM utilizes a unique, constraint-based methodology which
simultaneously considers a broad range of factors -- from changing revenue
forecasts to machine capabilities to individual customer commitments -- to
optimize all aspects of the supply chain.
 
     Since inception, the Company has significantly increased its investment in
sales and marketing, service and support, research and development and general
and administrative staff and accelerated such investment beginning in the last
quarter of 1995. As a result of the increased staffing, the Company has
experienced decreases in operating margins in 1995 and 1996. Operating margins
for 1997 decreased primarily due to costs and expenses related to acquisitions.
As a result of these investments, together with the increasing awareness of the
benefits of supply chain management in general and increased market acceptance
of the Company's products in particular, the Company's revenues in 1996 and the
1997 were substantially higher than the levels achieved in prior years. In order
to capture additional market share, the Company expects to continue to increase
staffing levels and incur additional associated costs in future periods through
both direct efforts and potential acquisitions. However, there can be no
assurance that the Company's revenues will grow in future periods or that the
Company will maintain the substantial growth rates in revenues it realized in
1996 and 1997.
 
     The sales cycle for the Company's products is typically six to nine months,
and license fee revenues for a particular period are substantially dependent on
orders received and software functionality delivered in that period.
Furthermore, the Company has experienced, and expects to continue to experience,
significant variation in the size of individual sales. As a result of these and
other factors, the Company's results have varied significantly in the past and
are likely to be subject to significant fluctuations in the future. Accordingly,
the Company believes that period-to-period comparisons of its results of
operations are not necessarily indicative of the results to be expected for any
future period. See "Business -- Additional Factors That May Affect Future
Results -- Potential for Significant Fluctuations in Quarterly Results;
Dependence on Significant Individual Sales" in Item 1 of this Form 10-K.
 
     In May 1997, the Company acquired Think Systems Corporation, a New Jersey
corporation ("Think"). Think provides premium demand chain solutions, including
an integrated line of flexible, client/server-based software applications, for
sales, marketing and logistics departments representing a variety of industries,
including consumer packaged goods, high technology, pharmaceutical, apparel,
automotive and other product-driven specializations. The Think merger culminates
an ongoing relationship commenced pursuant to a January 1996 agreement between
the Company and Think to integrate Think's demand management decision support
software and the Company's RHYTHM suite of planning and optimization software
products. Approximately 3.8 million shares of Common Stock have been issued or
are issuable to the former Think shareholders and optionholders in exchange for
all of the capital stock of Think and all unexpired and unexercised options to
acquire Think capital stock.
 
     Also in May 1997, the Company acquired Optimax Systems Corporation, a
Delaware corporation ("Optimax"). Optimax develops, markets and implements
supply chain sequencing software using unique genetic algorithms for
customer-driven, make-to-order manufacturing. Approximately 1.4 million shares
of Common Stock have been issued or are issuable to the former Optimax
stockholders and optionholders in
 
                                       20
<PAGE>   22
 
exchange for all of the capital stock of Optimax and all unexpired and
unexercised options to acquire Optimax capital stock.
 
     For accounting purposes, the Think and Optimax acquisitions were each
treated as a pooling of interests. Accordingly, the Company's consolidated
financial statements have been restated to give retroactive effect to the Think
and Optimax acquisitions and include the combined operations of the Company,
Think and Optimax for all periods presented. The following discussion and
analysis should be read in conjunction with such consolidated financial
statements.
 
     In April 1997, the Company acquired the Operations Planning Group ("OPG"),
a business activity of Computer Sciences Corporation, for a cash purchase price
of $1.0 million. OPG provides operation planning environment optimization
software for planning and scheduling for customers in the consumer packaged
goods industry. In November 1997, the Company acquired the remaining interest in
a minority owned subsidiary, M-Star Systems Limited ("M-Star"), for an aggregate
purchase price of $3.75 million. M-Star provides logistics software designed to
present a global view of a company's supply network on a real-time basis by
accessing the company's existing data resources. The acquisitions of OPG and
M-Star were accounted for under the purchase accounting method.
 
     In the second quarter of 1997, the Company incurred approximately $5.6
million in certain expenses related to the Think, Optimax and OPG acquisitions.
In the fourth quarter of 1997, the Company incurred approximately $3.7 million
in certain expenses related to the acquisition of M-Star. Of these expenses,
$4.6 million represents the write-off of in-process research and development.
The remaining costs included, among other things, investment banking, legal and
accounting fees and expenses. See "Business -- Additional Factors That May
Affect Future Results -- Integration of Recent Acquisitions; Potential Future
Acquisitions" in Item 1 of this Form 10-K.

  REVENUES
 
     The Company's revenues consist of software license revenues, service
revenues and maintenance revenues. Software license revenues consist of sales of
software licenses which were recognized upon execution of a contract and
shipment of the software, provided that no significant vendor obligations
remained outstanding, amounts were due within one year and collection was
considered probable by management. As discussed in the following paragraph,
software license revenue recognition for future periods has been revised.
Service revenues are primarily derived from fees for implementation, consulting
and training services and are recognized as the services are performed.
Maintenance revenues are derived from customer support agreements generally
entered into in connection with initial license sales and subsequent renewals.
Maintenance revenues are recognized ratably over the term of the maintenance
period. Payments for maintenance fees are generally made in advance.
 
     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") 97-2, "Software Revenue Recognition," which
provides guidance on applying generally accepted accounting principles in
recognizing revenue on software transactions. Under SOP 97-2, software license
revenues will be recognized upon execution of a contract and delivery of
software, provided that the license fee is fixed and determinable, no
significant production, modification or customization of the software is
required and collection is considered probable by management. The provisions of
SOP 97-2 are effective for the Company for transactions entered into after
December 31, 1997. The Company does not currently believe that the application
of SOP 97-2 will have a material impact on its consolidated financial
statements. However, because SOP 97-2 does not give specific implementation
guidance and no industry practice has been established regarding the provisions
of SOP 97-2, there can be no assurance that SOP 97-2 will not have a material
impact on the Company's revenue recognition practices, which could be material
to the Company's consolidated financial statements.
 
     Total revenues increased 128.3% to $200.7 million in 1997 from $87.9
million in 1996, and increased 188.0% in 1996 from $30.5 million in 1995. The
Company currently derives substantially all of its revenues from RHYTHM licenses
and related services and maintenance. The Company expects that RHYTHM related
revenues will continue to account for substantially all of the Company's
revenues in the foreseeable future. As a result of the Company's dependence on
the continued market acceptance of RHYTHM and enhancements thereto, there can be
no assurance that total revenues will continue to increase at the rates
experienced in prior periods, if at all. See "Business -- Additional Factors
That May Affect Future Results -- Product Concentration; Dependence on Product
Line Expansion" in Item 1 of this Form 10-K.
 
     SOFTWARE LICENSES. Revenues from software licenses increased 134.3% to
$134.7 million in 1997 from $57.5 million in 1996, and increased 180.0% in 1996
from $20.5 million in 1995. Software license revenues constituted 67.1%, 65.4%
and 67.2% of total revenues in 1997, 1996 and 1995, respectively. The
significant increases in the dollar amount of software license revenues were
primarily due to an increased awareness of the benefits of supply chain
management, growing market acceptance of the Company's software products, a
substantial investment in the Company's infrastructure and continued expansion
into new geographic and vertical markets. To date, sales of software licenses
have principally been derived from direct sales to customers. Although the
Company believes that direct sales will continue to account for a majority of
software license revenues, the Company's strategy is to increase the level of
indirect sales activities. The Company expects that sales of its software
products through sales alliances, distributors, resellers and other indirect
channels will increase as a percentage of software license revenues. However,
there can be no assurance that the Company's efforts to expand indirect sales
will be successful. See "Business -- Sales and Marketing" in Item 1 of this Form
10-K.
 
     SERVICES. Revenues from services increased 110.0% to $46.7 million in 1997
from $22.2 million in 1996, and increased 228.5% in 1996 from $6.8 million in
1995. Service revenues constituted 23.3%, 25.3% and 22.2% of total revenues in
1997, 1996, and 1995, respectively. The significant increases in the dollar
amount of service revenues were primarily due to the significant increase in the
number of RHYTHM licenses sold and a significant investment in the Company's
consulting organization as a result of the increased demand for the Company's
products. The increases were also due to an increase in the use of third-party
consultants to
 
                                       22
<PAGE>   24
 
provide implementation services to the Company's customers which has allowed the
Company to more rapidly penetrate international markets. Service revenues as a
percentage of total revenues have fluctuated, and are expected to continue to
fluctuate on a period-to-period basis based upon the demand for implementation,
training and consulting services.
 
     MAINTENANCE. Revenues from maintenance increased 136.1% to $19.3 million in
1997 from $8.2 million in 1996, and increased 153.6% in 1996 from $3.2 million
in 1995. Maintenance revenues constituted 9.6%, 9.3% and 10.6% of total revenues
in 1997, 1996 and 1995, respectively. The significant increases in the dollar
amount of maintenance revenues were primarily due to the continued increase in
the number of RHYTHM licenses sold and a high percentage of maintenance
agreement renewals. The Company expects that the dollar amount of maintenance
revenues will continue to increase, but maintenance revenues as a percentage of
total revenues should not vary significantly from the percentage of total
revenues achieved in 1997.
 
     CONCENTRATION OF REVENUES. During 1997, no individual customer accounted
for more than 10% of total revenues. During 1996, one customer accounted for
approximately 13% of total revenues. During 1995, this same customer accounted
for approximately 11% of total revenues, while one other customer accounted for
approximately 10% of total revenues. The Company believes that the loss of any
of these particular customers would not have a material adverse effect upon the
Company's business, operating results or financial condition.
 
     INTERNATIONAL REVENUES. The Company recognized $65.4 million, $20.6 million
and $2.2 million of revenues from international sources in 1997, 1996 and 1995,
representing approximately 33%, 23% and 7% of total revenues, respectively. The
Company's revenues from international sources were primarily generated from
customers located in Asia, Canada and Europe. In 1997, revenues from customers
located in Europe and Asia accounted for approximately 17% and 10% of total
revenues, respectively. In 1996, revenues from customers located in Europe
accounted for approximately 13% of total revenues. The significant increases in
revenues from international sources were primarily due to the continued
expansion of the Company's international sales and consulting operations as well
as software localization efforts. The Company believes that continued growth and
profitability will require expansion of its sales in international markets. In
order to successfully increase international sales, the Company has utilized and
will continue to utilize substantial resources to expand existing international
operations, establish additional international operations and hire additional
personnel. See "Business -- Additional Factors That May Affect Future
Results -- International Operations and Currency Fluctuations" in Item 1 of this
Form 10-K.
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 131, "Disclosures about Segments of
an Enterprise and Related Information," which establishes standards for the way
that public business enterprises report information about operating segments and
for related disclosures about products and services, geographic areas and major
customers. The provisions of SFAS No. 131 are effective for the Company
beginning in 1998. Although the Company currently operates in only one industry
segment, the Company is evaluating the potential impact of SFAS No. 131 on its
reporting requirements.
 
  COSTS AND EXPENSES
 
     COST OF SOFTWARE LICENSES. Cost of software licenses consists primarily of
(i) commissions paid to third parties in connection with joint marketing and
other related agreements, (ii) royalty fees associated with third-party software
included with the sales of RHYTHM, (iii) the cost of user documentation and (iv)
the cost of reproduction and delivery of the software. Cost of software licenses
was $3.4 million, $151,000 and $135,000 in 1997, 1996 and 1995, representing
2.5%, 0.3% and 0.7% of software license revenues, respectively. The significant
increase in cost of software licenses in 1997, both in dollar amount and as a
percentage of software license revenues, was primarily due to an increase in
commissions paid to third parties in connection with joint marketing and other
related agreements. Cost of software licenses decreased significantly in the
second half of 1997 as compared to the first half of 1997 as a result of the
termination of the license and distribution agreement with SAP pursuant to which
the Company was required to pay SAP a commission on RHYTHM products sold to
SAP's customers. The Company expects cost of software licenses to vary in the
future depending upon the amount of commissions due to other third parties in
connection with joint
 
                                       23
<PAGE>   25
 
marketing and other related agreements and the amount of royalty fees associated
with third-party software included with the sales of RHYTHM.
 
     COST OF SERVICES AND MAINTENANCE. Cost of services and maintenance consists
primarily of costs associated with implementation, consulting and training
services. Cost of services and maintenance also includes the cost of providing
software maintenance to customers such as hotline telephone support and
packaging and shipping costs related to new releases of software and updated
user documentation, none of which costs have been significant to date. Cost of
services and maintenance was $41.5 million, $18.6 million and $5.6 million in
1997, 1996 and 1995, representing 62.9%, 61.3% and 56.1% of total services and
maintenance revenues, respectively. The increases in cost of services and
maintenance both in dollar amount and as a percentage of total services and
maintenance revenues were primarily due to the increase in the number of
consultants, product support and training staff and the increased use of
third-party consultants to provide implementation services. In addition,
consulting and support centers were established and expanded in Canada, Europe
and Japan in the last three months of 1996 and during 1997. The Company expects
to continue to increase the number of its consulting, product support and
training personnel in the foreseeable future as a means to expand into different
geographic and vertical markets. To the extent that the Company's license sales
do not increase at anticipated rates, the hiring of additional personnel could
adversely affect the Company's gross margins.
 
     SALES AND MARKETING. Sales and marketing expenses consist primarily of
personnel costs, commissions, office facilities, travel, promotional events such
as trade shows, seminars and technical conferences, advertising and public
relations programs. Sales and marketing expenses were $69.9 million, $33.7
million and $9.9 million in 1997, 1996 and 1995, representing 34.8%, 38.4% and
32.3% of total revenues, respectively. The increases in the dollar amount of
sales and marketing expenses were primarily due to (i) increased staffing as the
Company established new domestic and international sales offices and expanded
its existing direct sales force, (ii) increased sales commissions as a result of
significantly higher revenues and (iii) increased marketing and promotional
activities. The decrease in sales and marketing expenses as a percentage of
total revenues in 1997 as compared to 1996 was primarily due to the Company's
ability to leverage its growing base of sales and marketing resources to
significantly increase revenues. The Company expects to continue to increase its
sales and marketing activities in order to expand its international sales
operations and to enter into new vertical markets. As a result, the Company
believes that the dollar amount of sales and marketing expenses will continue to
increase.
 
     RESEARCH AND DEVELOPMENT. Research and development expenses consist
primarily of the personnel and related costs associated with the Company's
research and development activities. Research and development expenses were
$44.1 million, $17.0 million and $5.5 million in 1997, 1996 and 1995,
representing 22.0%, 19.3% and 18.0% of total revenues, respectively. The
increases in research and development expenses both in dollar amount and as a
percentage of total revenues were primarily due to the hiring of additional
research and development personnel and other related costs incurred in
connection with expanding the Company's research and development centers,
particularly its international development facilities. The Company expects that
the dollar amount of research and development expenses will continue to increase
as the Company continues to invest in developing new products, applications and
product enhancements for new vertical markets.
 
     In accordance with 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 the Company's products and general release of such software have
substantially coincided. As a result, software development costs qualifying for
capitalization have been insignificant, and therefore, the Company has not
capitalized any software development costs.
 
     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of the personnel and other costs of the finance, human resources,
information systems, administrative and executive departments of the Company and
the fees and expenses associated with legal, accounting and other services.
 
                                       24
<PAGE>   26
 
General and administrative expenses were $18.6 million, $8.7 million and $4.6
million in 1997, 1996 and 1995, representing 9.3%, 9.9% and 15.2% of total
revenues, respectively. The increases in the dollar amount of general and
administrative expenses were primarily the result of increased staffing and
related costs associated with the growth of the Company's business during these
periods. The decreases in general and administrative expenses as a percentage of
total revenues were primarily due to the substantial increase in total revenues
and the Company's ability to leverage its base of resources to support a larger
organization. The Company expects that the dollar amount of general and
administrative expenses will continue to increase in the foreseeable future.
 
     IN-PROCESS RESEARCH AND DEVELOPMENT AND ACQUISITION COSTS. The Company
incurred approximately $9.3 million in certain acquisition-related expenses in
connection with the acquisitions of Think, Optimax and OPG which were recorded
in the second quarter of 1997 and in connection with the acquisition of M-Star
which was recorded in the fourth quarter of 1997. Of these expenses, $4.6
million represents the write-off of in-process research and development. The
remaining costs included, among other things, investment banking, legal and
accounting fees and expenses.
 
  OTHER INCOME (EXPENSE)
 
     Other income (expense) consists primarily of interest income on short-term
investments and overnight repurchase agreements offset by interest expense on
the Company's debt. Other income (expense) was $3.1 million, $1.8 million and
($117,000) in 1997, 1996 and 1995, representing 1.5%, 2.1% and (0.4%) of total
revenues, respectively. The increases in the dollar amount of other income
(expense) were primarily due to interest earned on higher balances of cash, cash
equivalents and short-term investments resulting from net proceeds of the public
offerings of the Company's common stock which were completed in May 1996 and
December 1997, and a decrease in interest expense due to the repayment of a
majority of the Company's outstanding debt in June 1996.
 
  PROVISION FOR INCOME TAXES
 
     The Company recorded income tax expense of $9.7 million, $4.3 million and
$1.6 million in 1997, 1996 and 1995, respectively. The Company's effective
income tax rates were 57.2%, 37.2% and 34.1% in 1997, 1996 and 1995,
respectively. The Company's effective income tax rate was higher in 1997 than in
1996 primarily due to the non-deductibility of certain of the
acquisition-related expenses. The Company's effective income tax rate was higher
in 1996 than in 1995 due to the non-deductibility of the amortization of
deferred compensation expense and higher effective state income tax rates.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since its inception, the Company has primarily financed its operations and
met its capital expenditure requirements through cash flows from operations,
long-term borrowings and sales of equity securities. Cash flows from operations
were $5.8 million, $6.7 million and $3.4 million in 1997, 1996 and 1995,
respectively. Operating cash flows decreased in 1997 as compared to 1996
primarily due to an increase in accounts receivable partially offset by
increases in the tax benefit from stock option activity, accrued liabilities and
accrued compensation and related expenses. Operating cash flows increased in
1996 as compared to 1995 primarily due to the tax benefit from stock option
activity and increases in net income, accounts payable, accrued liabilities,
accrued compensation and related expenses and deferred revenue, partially offset
by an increase in accounts receivable. The tax benefit from stock option
activity is primarily the result of disqualifying dispositions of stock acquired
under the Company's stock plans.
 
     Accounts receivable, net of allowance for doubtful accounts, increased to
$71.2 million at December 31, 1997 from $33.6 million at December 31, 1996,
primarily due to a continued significant increase in revenues. Based upon the
nature of the Company's customers and its past collection experience, the
Company does not expect to encounter collection difficulties with respect to
such accounts that would have a material effect on the Company's financial
position or results of operations.
 
                                       25
<PAGE>   27
 
     Average days' sales outstanding was 85 days for 1997 as compared to 76 days
for 1996. The increase in days' sales outstanding was primarily due to a
significant increase in receivables from international customers which tend to
have longer payment terms compared to customers located in the United States.
Additionally, the Company continues to experience larger sales for which some
amounts are not due upon execution of the contract. Average days' sales
outstanding can fluctuate for a variety of reasons including the timing and
billing of receivables for which the related revenues may not yet be
recognizable.
 
     Cash used in investing activities was $9.7 million for 1997 as compared to
$26.9 million for 1996. Cash used in investing activities was higher in 1996
than in 1997 primarily due to the initial investment of the net proceeds from
the initial public offering of the Company's common stock which was completed in
May 1996. Proceeds from the public offering of the Company's common stock which
was completed in December 1997 were invested primarily in financial instruments
classified as cash equivalents. At December 31, 1997, the Company did not have
any material commitments for capital expenditures.
 
     Cash provided by financing activities was $93.6 million for 1997 as
compared to $48.9 million for 1996. Cash provided by financing activities for
1997 includes the Company's net proceeds of $89.4 million from its December 1997
public offering of common stock. Cash provided by financing activities for 1996
includes the Company's net proceeds of $43.7 million from its initial public
offering of common stock which was completed in May 1996.
 
     As of December 31, 1997, the Company had $162.4 million of working capital,
including $125.9 million in cash and cash equivalents and $14.5 million in
short-term investments as compared to $58.8 million of working capital as of
December 31, 1996, including $36.1 million in cash and cash equivalents and
$18.0 million in short-term investments.
 
     The Company may in the future pursue additional acquisitions of businesses,
products and technologies, or enter into joint venture arrangements, that could
complement or expand the Company's business. Any material acquisition or joint
venture could result in a decrease to the Company's working capital depending on
the amount, timing and nature of the consideration to be paid.
 
     The Company has a revolving credit agreement with NationsBank of Texas,
N.A. (the "Lender") which expires in June 1998, is unsecured and contains
customary restrictive covenants, including covenants requiring the Company to
maintain certain financial ratios. The revolving credit agreement is not subject
to a borrowing base limitation and the borrowings thereunder bear interest at
the Lender's prime lending rate. At December 31, 1997, the Company had no
borrowings outstanding under the revolving credit agreement.
 
     The Company is currently evaluating what actions, if any, will be necessary
to make its internal systems Year 2000 compliant. Although any expenses
associated with these actions cannot presently be determined, the Company does
not currently expect such expenses to materially adversely affect its financial
position or results of operations.
 
     The Company believes that existing cash and cash equivalent balances,
short-term investment balances, available borrowings under the revolving credit
agreement and potential cash flow from operations will satisfy the Company's
working capital and capital expenditure requirements for at least the next 12
months. However, any material acquisitions of complementary businesses, products
or technologies could require the Company to obtain additional equity or debt
financing. There can be no assurance that such financing will be available on
acceptable terms, it at all.

i2 Technologies, Inc.
 
     We have audited the accompanying consolidated balance sheets of i2
Technologies, Inc. and its subsidiaries (the Company) as of December 31, 1996
and 1997, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. Our audits also included the financial statement schedule listed in
the index at Item 14(a). These financial statements and schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of i2
Technologies, Inc. and its subsidiaries at December 31, 1996 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles. Also, in our opinion, the related financial statement
schedule, when considered in relation to the basic financial statements taken as
a whole, presents fairly in all material respects the information set forth
therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. THE COMPANY
 
     i2 Technologies, Inc. (the "Company"), incorporated in 1989, develops,
markets and sells client/server-based decision support software products for
supply chain management and related applications. The Company also provides
services such as consulting, training and maintenance. The Company's products
and services are primarily provided to large and medium sized manufacturing and
distribution companies which operate in many industries located throughout the
world.
 
     In May 1997, the Company acquired Think Systems Corporation ("Think"), a
demand planner software company and Optimax Systems Corporation ("Optimax"), a
scheduling and sequencing software company. Each of these business combinations
was accounted for as a pooling of interests, and accordingly, the accompanying
consolidated financial statements give retroactive effect to the combinations
and include the combined operations of i2 Technologies, Think and Optimax for
all periods presented (see Note 3).
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     PRINCIPLES OF CONSOLIDATION. The accompanying consolidated financial
statements include the accounts of the Company and its subsidiaries. All
significant intercompany balances and transactions have been eliminated in
consolidation.
 
     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, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS. Cash equivalents are
highly liquid investments with insignificant interest rate risk and original
maturities of 90 days or less and are stated at amounts which approximate fair
value, based on quoted market prices. Cash equivalents consist principally of
overnight repurchase agreements and highly liquid debt securities of
corporations, municipalities and the U.S. Government.
 
     The Company accounts for its cash equivalents and short-term investments
under Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting
for Certain Investments in Debt and Equity Securities." Management determines
the appropriate classification of debt securities at the time of purchase and
reevaluates such designation as of each subsequent balance sheet date. The
Company considers its debt securities as "available-for-sale" and, in accordance
with SFAS No. 115, would record its investments at fair value. However, as the
difference between cost and fair value was immaterial at December 31, 1997, no
adjustment has been made to the historical carrying value of the investments and
no unrealized gains or losses have been recorded as a separate component of
stockholders' equity. Realized gains and losses to date have not been material.
The cost of debt securities sold is based on the specific identification method.
 
     The Company's debt securities include the following (in thousands):

equivalents, respectively. Interest income earned in 1995, 1996 and 1997 was
$179,000, $1.9 million and $3.1 million, respectively.
 
     FINANCIAL INSTRUMENTS. Financial instruments which potentially subject the
Company to a concentration of credit risk principally consist of accounts
receivable. As of December 31, 1996, approximately 27% of accounts receivable
were concentrated with three customers. As of December 31, 1997, approximately
31% of accounts receivable were concentrated with one of these same customers
and two different customers. The Company generally does not require collateral
on accounts receivable as the Company's customers are generally large, well
established companies. The Company periodically performs credit evaluations of
its customers and maintains reserves for potential losses. The Company has used
in the past and expects to use in the future foreign exchange contracts to hedge
the risk that receivables denominated in foreign currencies may be adversely
affected by changes in foreign currency exchange rates. The Company's foreign
exchange contracts outstanding at December 31, 1997 are immaterial. Gains and
losses on foreign exchange contracts have not been material to date.
 
     FURNITURE AND EQUIPMENT. Furniture and equipment are stated at cost.
Depreciation expense is calculated using the straight-line method over seven
years for office furniture and fixtures and three years for computer equipment.
 
     REVENUE RECOGNITION. The Company's revenues consist of software license
revenues, service revenues and maintenance revenues. Software license revenues
consist of sales of software licenses which were recognized upon execution of a
contract and shipment of the software, provided that no significant vendor
obligations remained outstanding, amounts were due within one year and
collection was considered probable by management. As discussed in the following
paragraph, software license revenue recognition for future periods has been
revised. Service revenues are primarily derived from fees for implementation,
consulting and training services and are recognized as the services are
performed. Maintenance revenues are derived from customer support agreements
generally entered into in connection with initial license sales and subsequent
renewals. Maintenance revenues are recognized ratably over the term of the
maintenance period. Payments for maintenance fees are generally made in advance.
 
     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") 97-2, "Software Revenue Recognition," which
provides guidance on applying generally accepted accounting principles in
recognizing revenue on software transactions. Under SOP 97-2, software license
revenues will be recognized upon execution of a contract and delivery of
software, provided that the license fee is fixed and determinable, no
significant production, modification or customization of the software is
required and collection is considered probable by management. The provisions of
SOP 97-2 are effective for the Company for transactions entered into after
December 31, 1997. The Company does not currently believe that the application
of SOP 97-2 will have a material impact on its consolidated financial
statements. However, because SOP 97-2 does not give specific implementation
guidance and no industry practice has been established regarding the provisions
of SOP 97-2, there can be no assurance that SOP 97-2 will not have a material
impact on the Company's revenue recognition practices, which could be material
to the Company's consolidated financial statements.
 
     Customer payment terms vary. Amounts received in advance of satisfying
revenue recognition criteria are classified in current and long-term liabilities
as deferred revenue in the accompanying consolidated balance sheets.
 
     The Company generally warrants that its products will function
substantially in accordance with documentation provided to customers for
approximately six to twelve months following initial shipment to the customer.
As of December 31, 1997, the Company had not incurred any significant expenses
related to warranty claims.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     SOFTWARE DEVELOPMENT COSTS. In accordance with 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 the Company's products and general
release of such software have substantially coincided. As a result, software
development costs qualifying for capitalization have been insignificant and
therefore, the Company has not capitalized any software development costs.
 
     NET INCOME PER SHARE. The Company computes net income per share in
accordance with the provisions of SFAS No. 128, "Earnings per Share." Net income
per share is based upon the weighted average number of common shares outstanding
and excludes the effect of dilutive potential common stock from the exercise of
stock options. Net income per share, assuming dilution, includes the effect of
dilutive potential common stock from the exercise of stock options using the
treasury stock method. In accordance with Securities and Exchange Commission
Staff Accounting Bulletins and Staff Policy, common shares and potential common
shares issued prior to the date of the initial filing of the Company's
Registration Statement on Form S-1 have been included in the net income per
share calculations for 1995 as if they were outstanding for the entire period.
Share and per share amounts for 1995 have been adjusted to reflect two stock
splits during 1995 (see Note 7). The computations give retroactive effect to the
exchange of common shares in connection with the Think and Optimax acquisitions
(see Note 3). Reconciliations of the net income per share computations for the
years ended December 31, 1995, 1996 and 1997 are included in Note 7.
 
     STOCK-BASED COMPENSATION PLANS. The Company has elected to continue to
account for its stock-based compensation plans utilizing the provisions of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," because, as discussed in Note 7, the alternative fair value
accounting provided for under SFAS No. 123, "Accounting for Stock-Based
Compensation," requires use of option valuation models that were not developed
for use in valuing employee stock options. However, SFAS No. 123 requires
disclosure of pro forma information regarding net income and net income per
share based on fair value accounting for stock-based compensation plans.
 
     FOREIGN CURRENCY TRANSLATION. The Company has determined that the
functional currency of the majority of its foreign subsidiaries is the local
currency. The financial statements of its foreign subsidiaries are translated
into U.S. dollars using the current rate method in accordance with SFAS No. 52,
"Foreign Currency Translation." To date, translation adjustments and foreign
currency gains and losses have not been significant and accordingly, have not
been separately presented.
 
     RECLASSIFICATIONS. Certain prior year financial statement items have been
reclassified to conform to the current year's format.
 
3. BUSINESS COMBINATIONS
 
     In May 1997, the Company acquired Think and Optimax. Under the terms of
these agreements, the Company has agreed to issue up to approximately
3.8 million shares and approximately 1.4 million shares of its common stock for
all the outstanding capital stock and all unexpired and unexercised options of
Think and Optimax, respectively.
 
     Think provides premium demand chain solutions, including an integrated line
of flexible, client/server-based software applications, for sales, marketing and
logistics departments representing a variety of industries including consumer
packaged goods, high technology, pharmaceutical, apparel, automotive and other
product driven specializations. Optimax develops, markets and implements supply
chain sequencing software using unique genetic algorithms for customer-driven,
make-to-order manufacturing.
 
     In April 1997, the Company completed the acquisition of the Operations
Planning Group ("OPG"), a business activity of Computer Sciences Corporation
("CSC"), for a cash purchase price of $1.0 million. OPG
                                       F-8

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
provides operation planning environment ("OPE") optimization software for
planning and scheduling for customers in the consumer packaged goods industry.
The Company assumed the contractual obligations of the OPE customer base in
return for $271,000 representing prepaid maintenance revenue. The acquisition
was accounted for under the purchase accounting method, and a substantial
portion of the purchase price was recorded as in-process research and
development and expensed during the second quarter of 1997. Additionally, the
Company has agreed to make available a certain amount of consulting revenue
opportunities to CSC within a three-year period from the date of the
acquisition. If the agreed upon consulting revenue opportunities are not made
available to CSC, the Company will be required to make an additional cash
payment to CSC at the end of the three-year period equal to the gross profit
typically realized on such consulting revenue. Such payment, if any, would be
recorded as an increase in the purchase price, a substantial portion of which
could be written off as in-process research and development.
 
     In November 1997, the Company acquired the remaining interest in a minority
owned subsidiary, M-Star Systems Limited ("M-Star"), for an aggregate purchase
price of $3.75 million. M-Star provides logistics software which can present a
global view of a company's supply network on a real-time basis by accessing the
company's existing data resources. The acquisition of M-Star was accounted for
under the purchase accounting method, and a substantial portion of the purchase
price was recorded as in-process research and development and expensed during
the fourth quarter of 1997.
 
     During 1997, the Company incurred approximately $9.3 million in certain
acquisition-related expenses in connection with the business combinations
involving Think, Optimax, OPG and M-Star, of which $4.6 million represents the
write-off of in-process research and development. The remaining costs included,
among other things, investment banking, legal and accounting fees and expenses.

5. BORROWINGS
 
     The Company has a revolving credit agreement with NationsBank of Texas,
N.A. (the "Lender") which expires in June 1998, is unsecured and contains
customary restrictive covenants, including covenants requiring the Company to
maintain certain financial ratios. The revolving credit agreement is not subject
to a borrowing base limitation and the borrowings thereunder bear interest at
the Lenders' prime lending rate. At December 31, 1996, the Company had $100,000
in borrowings outstanding under the revolving credit agreement. At December 31,
1997, the Company had no borrowings outstanding under the revolving credit
agreement.
 
     Cash paid for interest in 1995, 1996 and 1997 was approximately $255,000,
$248,000 and $15,000, respectively.

    of the Company's Registration Statement on Form S-1 are included in this
    line item for the year ended December 31, 1995. See Note 2.
 
     EMPLOYEE STOCK PURCHASE PLAN. In March 1996, the Board adopted and the
stockholders approved an Employee Stock Purchase Plan. In November 1996, the
Board adopted an International Employee Stock Purchase Plan for employees of its
wholly-owned subsidiaries. The Employee Stock Purchase Plan and the
International Employee Stock Purchase Plan (collectively, the "Purchase Plans")
are designed to allow eligible employees of the Company to purchase shares of
Common Stock through periodic payroll deductions. The Company has reserved
500,000 shares of Common Stock for issuances under the Purchase Plans.
 
     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 1,000 shares
per purchase period under the Purchase Plans. The purchase price per share will
be 85% of the lesser of the fair market value of the 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 with the Company. Six-month
offering periods will commence on each November 1 and May 1, except for the
initial offering period which commenced on April 25, 1996 and ended on October
31, 1996. Under the Purchase Plans, 60,145, 32,998 and 43,962 shares were issued
in connection with the offering periods ended October 31, 1996, April 30, 1997
and October 31, 1997, respectively.
 
     1992 STOCK PLAN. Under the Company's 1992 Stock Plan, the Company's Board
of Directors (the "Board") granted incentive stock options to employees of the
Company and nonqualified options to a

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
consultant of the Company. The options generally vest over a four-year period
commencing on or before the date of grant.
 
     1995 STOCK OPTION/STOCK ISSUANCE PLAN. In September 1995, the stockholder
and the Board approved the 1995 Stock Option/Stock Issuance Plan (the "1995
Plan") which replaced the 1992 Stock Plan. All options outstanding under the
1992 Stock Plan were incorporated into the 1995 Plan. Under the 1995 Plan, the
amount of shares of Common Stock originally reserved for issuance was 10,000,000
shares which was subsequently increased to 12,000,000 shares. The amount of
shares of Common Stock reserved for issuance was increased to 15,500,000 shares,
subject to the approval of the Company's stockholders. 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 ("Incentive Options") to employees of the Company and for the
grant of nonqualified stock options to employees, directors and consultants of
the Company. 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
options, respectively. 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 by the Company at the
original exercise price for all unvested shares.
 
     Under the Stock Issuance Program, the Board or a committee of the Board
(the "Plan Administrator") may grant shares of the Company's Common Stock to any
person at any time, at such price 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 the Company's 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 1,000 common shares of the Company at the fair
market value on the date of grant. On the date of each Annual Stockholders
Meeting each non-employee Board member shall automatically be granted an
additional option to purchase 1,000 shares of the Company's Common Stock,
subject to certain conditions.
 
     THINK STOCK OPTION PLANS. Think's Board of Directors have adopted and its
shareholders have approved stock option plans for employees, directors and
consultants of Think (the "Think Plans"). Under the Think Plans, the Think Board
of Directors granted incentive and nonqualified stock options to employees,
directors and consultants at prices not less than the estimated fair market
value of Think's common stock at the date of grant. In connection with the
acquisition of Think, all of the options outstanding under the Think Plans were
assumed by the Company.
 
     OPTIMAX STOCK OPTION PLAN. During 1996, Optimax's Board of Directors
adopted and its shareholders approved the Optimax Systems Corporation Stock
Option Plan (the "Optimax Stock Option Plan"). Under the Optimax Stock Option
Plan, the Optimax Board of Directors granted nonqualified stock options to
employees of Optimax at prices equal to the estimated fair market value of
Optimax's common stock on the date of grant. The options generally vest over a
five-year period commencing on or before the date of grant. In connection with
the acquisition of Optimax, all such options were assumed by the Company.

acquisition of the Company in a merger or asset sale, except to the extent the
Company's 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 which results in a change in control of the Company.
 
     All options outstanding at December 31, 1997 are Incentive Options except

     The Company recorded deferred compensation expense of $1.8 million and
$910,000 in 1995 and in the first quarter of 1996, respectively, for the
difference between the grant price and the deemed fair market value of the
Company's Common Stock underlying certain options granted. These amounts are
being amortized over the vesting period of the individual options, generally
four years. The income tax benefits from disqualifying dispositions related to
employee stock transactions have been recorded as an increase in additional
paid-in capital. As a result of these disqualifying dispositions, the Company
has an income tax receivable balance of $1.1 million at December 31, 1997.
 
     PRO FORMA NET INCOME AND NET INCOME PER SHARE. Pro forma information
regarding net income and net income per share has been determined as if the
Company had accounted for its employee stock options and shares issued under the
Purchase Plans using the fair value method of SFAS No. 123. The fair value for
the stock options issued under the 1995 Plan was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1995, 1996 and 1997, respectively: risk-free interest rates of
6.3%, 6.2% and 6.2%; volatility factors of the expected market price of the
Company's Common Stock of 0.46, 0.46 and 0.66; a weighted-average expected life
of the options of 4 years; and no dividend yields. The fair value of the stock
options issued under the Think Plans was estimated at the date of grant using
the minimum value method for non-public companies permitted by SFAS No. 123 with
the following assumptions for 1996 and 1997, respectively: weighted-average
risk-free interest rates of 6.5% and 6.2%; no dividends; and a weighted-average
expected life of the options of 7 years. The fair value of stock options issued
under the Optimax Stock Option Plan is not presented as the impact is
immaterial.
 
     The fair value for the shares issued under the 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 1996 and 1997,
respectively: risk free interest rates of 5.2% and 5.4%; volatility factors of
the expected market price of the Company's Common Stock of 0.46 and 0.66; a
weighted-average expected life of the purchase right of 0.5 years; and no
dividend yields. The weighted-average fair values of the purchase rights granted
under the Purchase Plans during 1996 and 1997 were $6.15 and $12.12,
respectively.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which 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 the Company's employee stock options have characteristics
significantly different from those of 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

     The Company considers 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. The Company believes that any
United States income taxes due upon the repatriation of such earnings would be
fully offset by foreign tax credits.
 
     The Company paid income taxes of approximately $3.1 million, $2.0 million
and $2.6 million in 1995, 1996 and 1997, respectively.
 
9. EMPLOYEE RETIREMENT PLAN
 
     The Company has established 401(k) retirement plans (the "Retirement
Plans") that cover a majority of the Company's employees. Eligible employees may
contribute up to 18% of their compensation, subject to certain limitations, to
the Retirement Plans. The Company may make contributions to the Retirement Plans
at the discretion of the Board. As of December 31, 1997, no contributions had
been made by the Company.

10. SEGMENT INFORMATION AND INTERNATIONAL OPERATIONS
 
     The Company operates in one industry segment, which is the development,
marketing, licensing and support of client/server-based decision support
software products for supply chain management and related applications. Revenues
from international sources were approximately $2.2 million, $20.6 million and
$65.4 million in 1995, 1996 and 1997, respectively. The Company's revenues from
international sources were primarily generated from customers located in Asia,
Canada and Europe. In 1996, revenues from customers located in Europe accounted
for 13% of total revenues. In 1997, revenues from customers located in Europe
and Asia accounted for approximately 17% and 10% of total revenues,
respectively. Total assets from international operations, composed primarily of
accounts receivable, were $11.4 million or 11% of total assets as of December
31, 1996 and were $38.0 million or 16% of total assets as of December 31, 1997.
 
     In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information," which
establishes standards for the way that public business enterprises report
information about operating segments and for related disclosures about products
and services, geographic areas and major customers. The provisions of SFAS No.
131 are effective for the Company beginning in 1998. Although the Company
currently operates in only one industry segment, the Company is evaluating the
potential impact of SFAS No. 131 on its reporting requirements.
 
11. MAJOR CUSTOMERS
 
     During 1995, two customers accounted for approximately 11% and 10% of total
revenues. During 1996, one customer accounted for approximately 13% of total
revenues. This customer also accounted for approximately 11% of total revenues
in 1995. During 1997, no customer accounted for more than 10% of total revenues.
 
12. RELATED PARTY TRANSACTIONS
 
     As of December 31, 1996, the Company had $1.0 million of notes receivable
from certain of its common stockholders. These notes bore interest at 6.78% and
were repaid in May 1997.
