ITEM 1. BUSINESS
 
    THIS REPORT CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF
SECTION 27A OF THE SECURITIES ACT OF 1933 AND SECTION 21E OF THE SECURITIES
EXCHANGE ACT OF 1934. THESE FORWARD-LOOKING STATEMENTS ARE SUBJECT TO CERTAIN
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY
FROM HISTORICAL RESULTS OR ANTICIPATED RESULTS, INCLUDING THOSE SET FORTH UNDER
"FACTORS THAT MAY AFFECT FUTURE RESULTS" UNDER "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" AND ELSEWHERE IN, OR
INCORPORATED BY REFERENCE INTO, THIS REPORT.
 
BACKGROUND
 
       The Company is a leading multinational supplier of information management
software. The Company designs, develops, manufactures, markets and supports
relational database management systems ("RDBMS"), connectivity interfaces and
gateways and application development tools for graphical and character-based
software applications as part of an RDBMS. Database management software permits
multiple individual users, employing different application software, to access
and manage the same data concurrently without corrupting the underlying
database. RDBMS software extends the functionality and utility of non-relational
database management software by simplifying the data retrieval process for end-
users, who do not require specific knowledge about the structure of the database
but need only to specify the data to be retrieved. Companies commonly employ
RDBMS software for use in storing, managing and retrieving the large amounts of
data necessary to support internal management information and decision-support
systems as well as mission-critical data processing applications.
 
       The Company believes that technological advances, including the
development and commercialization of the Internet, will lead to increasingly
sophisticated customer requirements for data storage and management beyond the
functionality offered by conventional RDBMS products. In recent years, the types
and quantities of data required to be stored and managed has grown increasingly
complex and includes, in addition to conventional character data, audio, video,
text and three dimensional graphics. In 1996, the Company devoted substantial
resources in the development of object-relational database management systems
("ORDBMS") and tools for applications in multimedia and entertainment, digital
media publishing and financial services.
 
       The Company markets its products to end-users on a worldwide basis
directly through its sales force and indirectly through application resellers,
OEMs and distributors. The principal geographic markets for the Company's
products are North America, Europe, the Asia/Pacific region and Latin America.
In recent years, approximately half of the Company's total revenues have been
generated outside North America. The Company's principal customers include
businesses ranging from small corporations to Fortune 1000 companies,
principally in the manufacturing, financial services, telecommunications, media,
retail/wholesale, hospitality and government services sectors.
 
       The Company was initially incorporated in California in 1980 and was
reincorporated in Delaware in August 1986. Unless the context requires
otherwise, the terms "Company" and "Informix" refer to Informix Corporation and
its subsidiaries. The Company maintains its executive offices at 4100 Bohannon
Drive, Menlo Park, California 94025. Its telephone number at that location is
(650) 926-6300.
 
PRODUCTS
 
    INFORMIX DYNAMIC SERVER
 
       Informix Dynamic Server is a high performance, enterprise capable online
transaction processing database server. This product is based on Informix's
Dynamic Scalable Architecture and features parallel data processing capability,
replication and connectivity options built into its core. Informix Dynamic
Server is available in a variety of configurations based upon adding one or more
of the configuration options described below.
 
                                       3
<PAGE>
       Informix also provides a version of Informix Dynamic Server called the
Workgroup Edition, which has been adapted specifically for workgroup
environments.
 
    SERVER CONFIGURATION OPTIONS
 
       Informix makes available five server configuration options, which are
integrated in various combinations along with Informix Dynamic Server to meet
specific customer requirements.
 
       The Advanced Decision Support Option extends Informix Dynamic Server with
a variety of decision support functions including summarization, sampling, and
"top-N."
 
       The Extended Parallel Option adapts Informix Dynamic Server to work
within loosely coupled, share-nothing computing architectures, including
clusters of symmetric multiprocessing systems and parallel processing systems.
 
       The Universal Data Option extends Informix Dynamic Server with support
for extensibility and SQL3. Extensibility includes the ability to add new
objects and data types, business specific procedures and logic, and new indexing
search methods to the server, as well as support for DataBlade modules, which
can include a related set of data types, functions and indexes for a specific
purpose.
 
       The MetaCube ROLAP Option adds an on-line analytical processing engine to
Informix Dynamic Server that automatically preconsolidates data and provides a
multidimensional view of data without the constraints of two dimensional (row
and table) data model. This option also includes MetaCube Explorer; MetaCube
Scheduler for batch processing; MetaCube Queryback for running queries in the
background; MetaCube Aggregator for creating and maintaining aggregates in a
data warehouse; MetaCube for Excel which enables data Warehouse analysis in an
Excel spreadsheet environment; and MetaCube for the Web which brings MetaCube
analysis capabilities to intranets.
 
       Finally, the Web Integration Option provides connectivity between Web
servers and Informix Dynamic Server. This option enables developers to create
intelligent web applications based upon database information that deliver
multimedia, tailored Web pages to users.
 
    DATABLADE MODULES
 
       DataBlade modules combine new data types, new functions or methods, and
new indexing operations, which taken together extend Informix Dynamic Server.
The DataBlade modules are used in conjunction with the Universal Data Option.
Informix sells the following DataBlade modules, and others are available through
Informix's partners:
 
       The Informix Video Foundation DataBlade module provides an open and
scalable software architecture that allows strategic third-party development
partners to incorporate specific video technologies such as video servers,
external control devices, compression codes or cataloging tools into database
management applications with the Informix Dynamic Server. In addition, the video
data types and data model allow customers to explore new ways to manipulate
video and associated metadata, or information about the video.
 
       The Informix TimeSeries DataBlade module expands the functionality of the
database by adding support for the management of time-series and temporal data.
The TimeSeries DataBlade module supports a regular or irregular repeating
time-stamped series of any datatype supported by Informix Dynamic Server or any
structure or combination of these. For example, a set of open, high, low, and
close currency values can be used to record a time-based series of stock prices.
The granularity of time recording can be adjusted to suit the unique
requirements of the application. The TimeSeries DataBlade module provides
support for three new datatypes, time-series, calendar and calendar pattern, and
over 80 functions to manage them. The time-series type stores sequences of
time-stamped information, and a related calendar allows access to specific
portions of the time series for update, analysis, display or other uses.
 
                                       4
<PAGE>
       The Informix Geodetic DataBlade module provides geo-spatial datatypes and
functions supporting two-dimensional representation of the earth's surface based
on a geodetic (longitude, latitude and datum) coordinate system. In addition to
two-dimensional geographic feature support, the Geodetic DataBlade Module allows
an altitude range and a time range to be specified.
 
    CONNECTIVITY PRODUCTS
 
       The Company's principal connectivity products include the following:
 
       Informix--Enterprise Gateway Manager is a connectivity tool allowing
applications running on various operating systems to access data sources via
loadable gateway drivers. The Company also offers gateway drivers for Oracle and
Sybase databases. Drivers for additional data sources are available from various
third parties.

SERVICES, CONSULTING AND CUSTOMER SUPPORT
 
       The Company maintains field-based and centralized corporate technical
staffs to provide a comprehensive range of assistance to its customers. These
services include pre- and post-sales technical assistance, consulting, product
and sales training and technical support services. Consultants and trainers
provide services to customers to assist them in the use of the Company's
products and the design and development of applications that utilize the
Company's products.
 
       The Company provides post-sales support to its customers on an optional
basis for annual fees which generally range from 12% to 18% of the license fees
paid by the customer. These support services usually include product updates.
 
       During fiscal 1996 and the first quarter of fiscal 1997, as part of its
sales and marketing strategy, the Company launched a series of "Information
SuperStores." The Superstores were intended to demonstrate and offer the
Company's software products to customers on actual hardware platforms used by
those customers, thereby permitting the end-user to evaluate and monitor the
performance and functionality of the Company's products prior to purchase. In
addition, the Superstores offered application tools from leading third-party
tools and application vendors installed on a variety of platforms, including
Data General Corporation, Hewlett-Packard Company, International Business
Machines ("IBM"), NCR Corporation/Teradata ("NCR/Teradata"), Pyramid, Sequent
Computer Systems, Inc. ("Sequent"), Silicon Graphics and Sun Microsystems. In
connection with the Company's restructuring announced in the second quarter of
fiscal 1997, the Company scaled back its original plans and repositioned its
remaining sites as solution labs managed by the Company's consulting practice.
The decision to scale back the Superstores resulted in a charge to operating
results during fiscal 1997 of approximately $37.0 million. See Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Restructuring Charges.
 
MARKETING AND CUSTOMERS
 
       The Company distributes its products through the channels of direct
end-user licensing, OEMs, application vendors addressing specific markets and
distributors. The Company has chosen a multiple channel distribution strategy to
maintain broad market coverage and product availability. The Company, therefore,
has generally avoided exclusive relationships with its licensees and other
resellers of its products. Discount policies and reseller licensing programs are
intended to support each distribution channel with a minimum of channel
conflict. The Company also provides a financing option to customers in
connection with the license of software. For fiscal 1997, sales of licenses
directly to end users accounted for 58% of total license revenues and sales to
OEM's and sales through resellers accounted for 42% of total license revenues.
 
       At December 31, 1997, the Company's sales, marketing and support staff
totaled 986 regular employees in the North America region; 128 regular employees
in the Latin America region; 619 regular employees in Europe, the Middle East
and Africa; and 369 regular employees in the Asia/Pacific region.
 
LICENSING
 
    END-USER LICENSING
 
       The Company licenses its products to large companies and government
entities through its direct sales force, and to certain of these companies, as
well as smaller end-users, through its telemarketing sales force. The Company
believes that the common core technology of its database management system
products, based on standard operating systems and the SQL database language,
helps it sell into major corporations and government agencies that wish to
standardize their diverse computing environments. As a result, certain of these
end-user organizations have entered into general purchasing agreements with the
Company which offer volume discounts.
 
                                       6
<PAGE>
    APPLICATION VENDOR LICENSING
 
       Since its inception, the Company has licensed application vendors to
distribute its products. A typical application vendor develops an application
product (E.G., an insurance agency management system) using one of the Company's
products and then licenses the resultant application software to its customers
in the target market. The application vendor customer purchases a license for
use of the Company's product to develop an applications program. Depending on
the application program developed, it may include a run-only license, a full
version license or even multiple product licenses.
 
       Application vendors develop applications using a wide array of
application development tools, including products from the Company, such as
Informix--NewEra, Informix--4GL and Informix--SQL, as well as products offered
by third parties. Applications developed using the Company's products are
generally portable across various brands of computers and different operating
systems.
 
       The Company has specialized programs to support the application vendor
distribution channel. Under these programs, the Company provides to selected
application vendors a combination of marketing development services, consulting
and technical marketing support and discounts.
 
    OEM LICENSING
 
       The Company's products are also marketed with the assistance of the sales
forces of its OEM customers who have concluded that "solution selling" of a
combination of software and hardware to their respective customers enhances the
sales of their computer equipment. The Company believes that the compatibility
and range of applications for its products are significant to this distribution
channel.
 
    DISTRIBUTOR LICENSING
 
       The Company has established a network of full service international
distributors who provide local service and support, as well as the Company's
products, to their respective national markets. Distributors are used to
supplement the Company's direct sales force and enable the Company to sell its
products and services in countries where the Company has not established a
direct sales force.
 
PRODUCT DEVELOPMENT
 
       The computer software industry is highly competitive and rapidly
changing. Consequently, the Company dedicates considerable resources to research
and development efforts to enhance its existing product lines and to develop new
products to meet new market opportunities. Most of the Company's current
software products and accompanying documentation have been developed internally;
however, the Company has acquired certain software products from others and
plans to do so again in the future.
 
       Major product releases resulting from research and development projects
in fiscal 1997 included the new releases of Informix Dynamic Server; Universal
Data Option; Extended Parallel Option; Advanced Decision Support Option;
Informix Dynamic Server, Workgroup Edition; and the initial release of Web
Integration Option.
 
       The Company's current product development efforts are focused on (i)
improving and enhancing current products and new products, with particular
emphasis on parallel computer architecture, user-defined database extensions,
Web technology integration, graphical desk top and system administration; (ii)
improving the Company's products to provide greater speed and support for larger
numbers of concurrent users; and (iii) adapting new products to the broad range
of computer brands and operating systems the Company currently supports and
adapting current products to new brands of computers and operating systems which
represent attractive market opportunities for the Company's products.
 
       There can be no assurance that the Company's product development efforts
will be successful or that any new products will achieve significant market
acceptance.
 
                                       7
<PAGE>
       As of December 31, 1997, the Company had 941 regular employees engaged in
research and development. In recent months, the Company has experienced high
attrition in its product development group and has had difficulty attracting
qualified replacement development personnel. Failure to attract and retain a
sufficient number of qualified development personnel would have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
       The Company's research and development expense for fiscal 1997, 1996 and
1995 was $139.3 million, $120.2 million and $85.6 million, respectively,
representing approximately 21%, 16% and 14% of revenues for such periods. In
addition, during fiscal 1997, 1996, and 1995 the Company capitalized product
development costs of $21.8 million, $28.4 million and $17.5 million,
respectively, in accordance with Statement of Financial Accounting Standards No.
86. See "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Research and Development Expenses."
 
       The market for the Company's products and services is characterized by
rapidly changing technology, changing customer needs, frequent new product
introductions and evolving industry standards that may render existing products
and services obsolete. The life cycles of the Company's products are difficult
to estimate. The Company's growth and future financial performance will depend
upon its ability to enhance its existing products and to introduce new products
on a timely and cost-effective basis and that meet dynamic customer
requirements. There can be no assurance that the Company will be successful in
developing new products or enhancing its existing products or that such new or
enhanced products will receive market acceptance or be delivered timely to the
market. The Company's product development efforts are expected to continue to
require substantial investments by the Company, and there can be no assurance
that the Company will have sufficient resources to make the necessary
investments. The Company has experienced product development delays in the past
and may experience delays in the future. Delays in the scheduled availability or
a lack of market acceptance of its products or failure to accurately anticipate
customer demand and meet customer performance requirements, including as a
result of recent attrition in the Company's product development group, could
have a material adverse effect on the Company's business results of operations
and financial condition. In addition, products as complex as those offered by
the Company may contain undetected errors or bugs when first introduced or as
new versions are released. There can be no assurance that, despite testing, new
products or new versions of existing products will not contain undetected errors
or bugs that will delay the introduction or commercial acceptance of such
products. A key determinative factor in the Company's success will continue to
be the ability of the Company's products to operate and perform well with
existing and future leading, industry-standard application software products
intended to be used in connection with RDBMS. Failure to meet existing or future
interoperability requirements of certain independent vendors and performance
requirements of certain independent vendors marketing such applications in a
timely manner could adversely affect the market for the Company's products.
Commercial acceptance of the Company's products and services could also be
adversely affected by critical or negative statements or reports by brokerage
firms, industry and financial analysts and industry periodicals concerning the
Company, its products, business or competitors or by the advertising or
marketing efforts of competitors, or other factors that could affect consumer
perception.
 
       In recent years, the types and quantities of data required to be stored
and managed has grown increasingly complex and includes, in addition to
conventional character data, audio, video, text, and three dimensional graphics.
In 1996, the Company devoted substantial resources in developing the Company's
ORDBMS product line. The market for the products offering object-relational
database functionality is new and evolving, and its growth depends upon a
growing need to store and manage complex data and on broader market acceptance
of the Company's products as a solution for this need. There can be no assurance
that organizations will chose to make the transition from conventional RDBMS to
ORDBMS. Delays in market acceptance of object-relational database management
products offered by the Company could have an adverse effect on the Company's
results of operations and financial condition.

COMPETITION
 
       Competitors in the relational database software market compete primarily
on the basis of product price and performance characteristics, name recognition,
technical product support, product training and services. With respect to
product performance, the Company believes that the principal competitive factors
include (i) application development productivity (I.E., the speed with which
applications can be built); (ii) database performance (I.E., the speed at which
database storage and retrieval functions are executed); (iii) product function
and features; (iv) the ability to support large warehouses of information; (v)
reliability, availability and serviceability; (vi) the distribution of software
applications and data across networks of computers from multiple suppliers; and
increasingly (vii) the ability to manage complex data and solve more complex
business problems based on such data. Although the Company believes that it
currently competes favorably with respect to such factors, there can be no
assurance that the Company can maintain its competitive position against current
and potential competitors, especially those with greater financial, marketing,
service, support, technical and other resources. The Company believes that the
technical advantages of its products, its approach to sales and marketing, its
relations with application vendors, OEMs and distributors and its customer
service and support contribute to its ability to compete in this market.
 
       The Company faces intense competition in the market for RDBMS software
products. The market for the Company's products is subject to rapid
technological change and frequent new product introductions and enhancements,
and the Company's competitors in the market include several large vendors that
develop and market databases, applications, development tools or decision
support products. The Company's principal competitors include Computer
Associates International, Inc. ("Computer Associates"), IBM, Microsoft
Corporation ("Microsoft"), NCR/Teradata, Oracle Corporation ("Oracle") and
Sybase, Inc. ("Sybase"). Several of these competitors have significantly greater
financial, technical, marketing and other resources than the Company. As a
result, they may be able to respond more quickly to new or emerging technologies
and changes in customer requirements or to devote greater resources to the
development, promotion and sale of their products than the Company. Any failure
by the Company to compete successfully with its existing competitors or future
competitors could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
       Several of the Company's competitors have announced the development of
enhanced versions of their principal database products that are intended to
improve the performance or expand the capabilities of their existing products.
New or enhanced products by existing competitors or new competitors could result
in greater price pressure on the Company's products. In addition, the industry
movement to new operating systems, like Windows NT, access through low-end
desktop computers, and access to data through the Internet may cause downward
pressure on prices of database software and related products. The bundling of
software products for promotional purposes or as a long-term pricing strategy by
certain of the Company's competitors could also result in reductions in the
price the Company may charge for its products. If such downward pressure on
prices were to occur, the Company's operating margins would be adversely
affected. Existing and future competition or changes in the Company's product or
service pricing structure or product or service offerings could result in an
immediate reduction in the prices of the Company's products or services. If
significant price reductions in the Company's products or services were to occur
and not be offset by increases in sales volume, the Company's business, results
of operation and financial condition would be adversely affected. There can be
no assurance that the Company will continue to compete successfully with its
existing competitors or will be able to compete successfully with new
competitors.
 
       In addition, the Company's public announcement in August 1997 of the
pending restatement of its financial statements, delays in reporting operating
results for the second and third quarters of fiscal 1997 while the restatement
was being compiled, threatened de-listing of the Company's Common Stock from the
Nasdaq National Market as a result of the Company's failure to satisfy its
public reporting obligations, corporate actions to restructure operations and
reduce operating expenses and customer uncertainty
 
                                       9
<PAGE>
regarding the Company's financial condition adversely affected the Company's
ability to sell its products in fiscal 1997. In addition, since the beginning of
1997, the Company and its competitors in the RDBMS industry have experienced
substantially slower growth in the market for RDBMS products. The financial
restatement has now been completed, its results have been publicly disclosed and
the Company is current with respect to its public reporting obligations. In
addition, the Company believes that it has effectively controlled its operating
expenses and significantly improved its financial condition. Nevertheless, there
can be no assurance that uncertainties resulting from the restatement, including
ongoing customer concern about the Company's financial condition, will not
continue to have a materially adverse effect on the Company's competitive
position and results of operations.
 
INTELLECTUAL PROPERTY
 
       The Company's success depends on proprietary technology. To protect its
proprietary rights, the Company relies primarily on a combination of patent,
copyright and trademark laws, trade secrets, confidentiality procedures,
contractual provisions contained in its license agreements and technical
measures. The Company seeks to protect its software, documentation and other
written materials under trade secret and copyright laws, which provide only
limited protection. The Company holds one United States patent and several
pending applications. There can be no assurance that any other patents covering
the Company's inventions will issue or that any patent, if issued, will provide
sufficiently broad protection or will prove enforceable in actions against
alleged infringers.
 
       The Company's products are generally licensed to end-users on a
"right-to-use" basis pursuant to a license that restricts the use of the
products for the customer's internal business purposes. The Company also relies
on "shrink wrap" licenses, which include a notice informing the end-user that,
by opening the product packaging, the end-user agrees to be bound by the
Company's license agreement printed on the package. Despite such precautions, it
may be possible for unauthorized third parties to copy aspects of its current or
future products or to obtain and use information that the Company regards as
proprietary. In particular, the Company has licensed the source code of its
products to certain customers under certain circumstances and for restricted
uses. The Company has also entered source code escrow agreements with a number
of its customers that generally require release of source code to the customer
in the event of the Company's bankruptcy, liquidation or otherwise ceasing to
conduct business. There can be no assurance that the Company's means of
protecting its proprietary rights will be adequate or that the Company's
competitors will not independently develop similar or superior technology.
Policing unauthorized use of the Company's software is difficult, and while the
Company is unable to determine the extent to which piracy of its software
products exists, software piracy can be expected to be a persistent problem. In
addition, the laws of some foreign countries do not protect the Company's
proprietary rights to the same extent as do the laws of the United States, and
"shrink-wrap" licenses may be wholly or partially unenforceable under the laws
of certain jurisdictions. Litigation may be necessary in the future to enforce
the Company's intellectual property rights, to protect the Company's trade
secrets or to determine the validity and scope of the proprietary rights of
others. Such litigation could result in substantial costs and diversion of
resources and management attention and could have a material adverse effect on
the Company's business, results of operations and financial condition.
 
       The Company is not aware that any of its software product offerings
infringe the proprietary rights of third parties. There can be no assurance,
however, that third parties will not claim infringement by the Company with
respect to its current or future products. The Company expects that software
product developers will increasingly be subject to infringement claims as the
number of products and competitors in the Company's industry segment grows and
the functionality of products in different industry segments overlaps. 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 licensing agreements, if
required, may not be available on terms acceptable to the Company or at all,
which could have a material adverse effect on the Company's business, results of
operations and financial condition.

EMPLOYEES
 
       As of December 31, 1997, the Company and its subsidiaries had 3,489
regular employees worldwide, including 2,102 in sales, marketing and support;
941 in research and development; 69 in operations and 377 in administration and
finance. Of the Company's total employees at December 31, 1997, approximately
1,447 were located outside North America. None of the Company's U.S. employees
are represented by a labor union. A small number of employees located outside of
the United States are represented by labor unions, and the degree and scope of
representation varies from country to country. The Company has not experienced
any work stoppages either domestically or internationally.
 
       Since the first quarter of fiscal 1997, the Company has experienced a
significant number of voluntary resignations and has taken selective actions to
reduce the number of employees in certain functional areas. The Company had
3,489 employees at December 31, 1997, compared to 4,491 at December 31, 1996. In
fiscal 1997, the Company experienced high attrition rates in its product
development and sales groups and has had trouble attracting qualified
replacement personnel. The competition for employees in the software industry is
intense, and the Company expects that such competition will continue for the
foreseeable future. The Company has experienced difficulty in locating
candidates with appropriate qualifications and believes that recent financial
and business developments at the Company have made recruitment more difficult.
 
ITEM 2. PROPERTIES
 
       The Company's headquarters and its principal marketing, finance, sales,
administration, customer service and research and development operations are
located in five buildings in a corporate office park in Menlo Park, California.
The Company currently leases approximately 214,000 square feet of space in these
buildings. The leases for space in two of these buildings expire in September
2001. The leases for spaces in the remaining three of the buildings were
recently renewed for an additional five year term expiring in March 2003. In
addition, the Company leases space totalling approximately 33,000 square feet in
two additional buildings in close proximity. These leases expire in May 1998 and
October 2000. The Company anticipates renewing the lease expiring in May 1998 at
prevailing market rates.
 
       In addition, certain of the Company's research and development
facilities, a portion of its customer service organization, its principal
domestic manufacturing facility and its telemarketing organization are located
in a 134,000 square foot facility in Lenexa, Kansas. The buildings are leased to
the Company under a lease expiring in April 2003, subject to renewal for up to
two additional five year terms. The Lenexa, Kansas facility was leased to the
Company by a partnership of which the Company held a 50% partnership interest.
The Company entered an agreement to sell its interest in 49.9% of the
partnership to the other partner. Such sale closed in the first quarter of
fiscal 1998. The Company also leases office space, principally for sales and
support offices, in a number of facilities in the United States, Canada and
outside North America. The Company believes that its current facilities are
adequate to meet its needs through the next twelve months.
 
       Some of the research and development operations for the Company's tools
products and a portion of customer service and sales training are located in
Oakland, California. The Company leases approximately 130,000 square feet at
this site, and the lease expires in May 2003. The Company also leases 47,276
square feet in Portland, Oregon, primarily for its research and development
group. The lease on approximately one-half of this space expires on October 31,
1998. The lease on the remaining space expires in March 2000.
 
       In December 1996, the Company announced plans to relocate its corporate
headquarters from the Menlo Park facilities to a new corporate campus in Santa
Clara, California. In January 1997, the Company entered into a two-year lease
for 27 acres of undeveloped commercial real estate in Santa Clara, which was
intended to be used for construction of the new headquarters facility. The
Company also obtained an option to purchase the land for $61.5 million. In order
to secure performance of its obligations under the
 
                                       11
<PAGE>
lease, the Company pledged $61.5 million in cash collateral to the lessor. In
April 1997, the Company exercised its option to purchase the land, and in
December 1997 completed the sale of the real estate for net proceeds of
approximately $59.3 million. In addition, in November 1996, the Company had
leased approximately 200,000 square feet of office space in Santa Clara on
property located adjacent to the 27 acre undeveloped parcel. In December 1997,
the Company assigned its rights under such lease agreement to an unrelated third
party, although the Company remains contingently liable for the lease payments
thereunder.
 
ITEM 3. LEGAL PROCEEDINGS
 
ACTIONS ARISING UNDER FEDERAL AND STATE SECURITIES LAWS
 
       Beginning on or about April 16, 1997, a total of 24 complaints alleging
violations of the federal securities laws were filed against the Company, Ernst
& Young LLP, the Company's independent auditors and certain Named Individual
Defendants (listed below) in the United States District Court for the Northern
District of California. Of the 24 complaints, 22 have been filed as purported
class actions by individuals who allege that they are individual investors who
purchased the Company's Common Stock during the purported class period; the
alleged class periods in the different complaints vary according to the date on
which the complaints were filed. The complaints name some or all of the
following current and former officers and directors of the Company as
defendants: Phillip E. White, Howard H. Graham, David H. Stanley, Ronald M.
Alvarez, Karen Blasing, D. Kenneth Coulter, Ira H. Dorf, Stephen E. Hill, Myron
(Mike) Saranga, Steven R. Sommer, MichaelR. Stonebraker and Edwin C. Winder (the
"Named Individual Defendants"). On August 20, 1997, the District Court entered
an order consolidating all of the separately-filed class actions pending at that
time, designating the action as IN RE INFORMIX CORPORATION SECURITIES
LITIGATION, and designating as "related cases" all cases brought under the
federal securities laws then pending and any that may be filed after that date.
A consolidated amended class action complaint was filed on April 6, 1998. As
required by the provisions of the Exchange Act, as amended by the Private
Securities Litigation Reform Act of 1995, the Court has designated the lead
plaintiffs in the federal action and has appointed lead plaintiffs' counsel.
 
       Two related non-class actions, TEACHERS' RETIREMENT SYSTEM OF LOUISIANA
ET AL. V. INFORMIX CORPORATION ET AL. and STATE BOARD OF ADMINISTRATION OF
FLORIDA V. INFORMIX CORPORATION ET AL., have been consolidated with IN RE
INFORMIX CORPORATION SECURITIES LITIGATION for all pre-trial purposes. The
LOUISANA and FLORIDA plaintiffs request a total of $10.173 million in damages.
An amended consolidated complaint was filed by the LOUISIANA and FLORIDA
plaintiffs on April 3, 1998.
 
       The existing federal court complaints allege that the Company, the Named
Individual Defendants and Ernst & Young issued false or misleading statements in
the Company's filings with the Commission, press releases, statements to
securities analysts and other public statements regarding its financial results
and business prospects. The alleged class period in the amended consolidated
complaints extends from February 7, 1995 through November 18, 1997. In
particular, plaintiffs allege that defendants overstated the Company's revenue
and earnings during the time period by improperly recognizing revenue from sales
of software licenses. All of these actions allege that the defendants' false and
misleading statements violate section 10(b) of the Exchange Act and Rule 10b-5
promulgated thereunder. The complaints further allege that the Named Individual
Defendants sold the Company's Common Stock while in the possession of adverse
material non-public information. The existing complaints, in general, do not
specify the amount of damages that plaintiffs seek.
 
       On or about March 19, 1998, a complaint alleging securities and common
law fraud and misrepresentation causes of action was filed in the United States
District Court for the Northern District of California. This complaint,
captioned WILLIAMS V. INFORMIX CORPORATION, ET AL., alleges both individual and
class claims on behalf of former securities holders of Illustra Information
Technologies, Inc. ("Illustra") who exchanged their Illustra securities for
securities of the Company in February 1996 in connection with
 
                                       12
<PAGE>
the Company's February 1996 acquisition of Illustra pursuant to an Agreement and
Plan of Reorganization (the "Illustra Agreement"). This matter has been
consolidated with IN RE INFORMIX CORPORATION SECURITIES LITIGATION. The WILLIAMS
complaint, like the previously-filed federal complaints, alleges that the
Company and certain of its former officers and/or directors, and its independent
auditors, issued false or misleading statements regarding the Company's reported
financial results and business prospects. Defendants are scheduled to file a
response to the consolidated, amended complaint on June 16, 1998.
 
       Three purported securities class actions containing allegations similar
to the federal actions were filed in the Superior Court of the State of
California, County of San Mateo between May 19, 1997 and August 25, 1997. Those
actions, captioned RILEY V INFORMIX CORPORATION ET AL., DAYANI V. INFORMIX
CORPORATION ET AL., AND GOLDSTEIN V. WHITE ET AL., contained factual allegations
nearly identical to the allegations set forth in the federal court complaints.
The Superior Court has consolidated these actions into the DAYANI case, and has
appointed lead plaintiffs' counsel. By stipulation, plaintiffs filed a
consolidated, amended complaint on December 23, 1997. The state court
consolidated, amended complaint names as defendants the Company, Ernst & Young
and the Named Individual Defendants. The claims in the consolidated amended
state complaint arise under California securities, fraud and unfair business
practices statutes.
 
       The state court consolidated, amended complaint alleges that the
defendants issued false financial statements which were not prepared in
conformity with Generally Accepted Accounting Principles for fiscal years 1996,
1995 and 1994, materially overstating the Company's revenue. Plaintiffs allege
that defendants recorded as revenue approximately $300 million from software
license sales which should not have been recorded because INTER ALIA, revenue
was recognized on sales to resellers before end-users were identified; revenue
was recognized in circumstances where customers had rights of return or
cancellation; and the Company recognized revenue from barter transactions in
which the Company allegedly exchanged software licenses for products that had no
value to the Company. Plaintiffs further allege that while the Company's stock
price was artificially inflated due to the overstatement of revenue, the
defendants used the Company's stock to make corporate acquisitions, and the
Named Individual Defendants sold stock while in possession of material adverse
non-public information. The alleged class period in the state court
consolidated, amended complaint is February 7, 1995 through November 18, 1997.
 
       Defendants filed demurrers to the state court consolidated, amended
complaint on February 13, 1998. Defendants base their demurrers to the
consolidated, amended complaint in this action on the grounds that certain of
the individual defendants made no actionable statements during the alleged class
period, the Company did not engage in any market activity during the alleged
class period, the plaintiffs did not actually rely upon any of the alleged false
and misleading statements, the California statutory unfair business practices
claims are inapplicable to securities transactions, and the consolidated,
amended complaint fails to plead the alleged fraud with sufficient
particularity. The hearing on defendants' demurrers is set for May 29, 1998. The
Company will not file an answer in this action unless the Court overrules the
pending and any subsequent demurrers. Further, the Company is not in a position
to state its factual defenses to the consolidated, amended complaint until the
Court rules upon the pending and any subsequent demurrers.
 
    DERIVATIVE ACTIONS
 
       The Company also was named as a nominal defendant in eight derivative
actions, purportedly brought on its behalf, filed in the Superior Court of the
State of California, County of San Mateo. The cases have been consolidated under
the caption IN RE INFORMIX CORPORATION DERIVATIVE LITIGATION, and the Court has
appointed lead plaintiff's counsel in the consolidated actions. The
consolidated, amended complaint alleges that, based upon the facts alleged in
the federal and state securities class actions, defendants breached their
fiduciary duties to the Company, engaged in abuses of their control of the
Company, were unjustly enriched by their sales of the Company's Common Stock,
engaged in insider trading in violation of California law and published false
financial information in violation of California law. The consolidated, amended
complaint names as defendants Ernst & Young, the Named Individual
 
                                       13
<PAGE>
Defendants and Albert F. Knorp, Jr., James L. Koch, Thomas A. McDonnell and
Cyril J. Yansouni, non-management directors of the Company. The plaintiff seeks
unspecified damages on the Company's behalf from each of the defendants. On
December 18, 1997, plaintiffs served their first amended, consolidated
derivative complaint.
 
       The Company, on whose purported behalf the derivative action is asserted,
and the individual defendants and Ernst & Young, against whom the claims are
alleged, filed demurrers to the consolidated derivative complaint on February 6,
1998. The Company's demurrer in this action is based upon the fact that the
plaintiff did not make demand on the Company's board prior to filing the
derivative action as is required by governing Delaware law. In addition, the
Company's current and former officers and directors have brought demurrers to
the consolidated, amended complaint on the grounds that plaintiffs fail to plead
any of their claims with sufficient particularity and that certain of
plaintiffs' California statutory causes of action do not apply, by their terms,
to officers and directors of a Delaware corporation. On April 1, 1998, the Court
sustained Informix's demurrer based upon the plaintiffs' failure to make demand.
The Court has given plaintiffs leave to amend their complaint. In addition, the
Court has kept on its calendar the defendants' demurrers based upon the lack of
merit in plaintiffs' substantive claims. That hearing is set for May 29, 1998.
The Company will not file an answer in this action unless the Court overrules
the pending or any subsequent demurrers. Further, the Company is not in a
position to state its factual defenses to the consolidated, amended complaint
until the Court rules upon the pending demurrers. Because of the nature of
derivative litigation, any recovery in the action would inure to the benefit of
the Company.
 
    INDEMNIFICATION AGREEMENTS AND LIABILITY INSURANCE
 
       Pursuant to Delaware law, the Company's Certificate of Incorporation, its
Bylaws and the indemnification agreements between the Company and each of its
current and former officers and directors, the Company is obligated to indemnify
its current and former officers and directors for certain liabilities arising
from their employment with or service to the Company. These indemnification
obligations require the Company to indemnify its current and former officers and
directors for any suit or other proceeding, threatened or actual, whether civil,
criminal, administrative, investigative, appellate or any other type of
proceeding, that arises as a result of any act or omission in the indemnitee's
capacity as an officer or director of the Company to the fullest extent
permitted under Delaware or any other applicable law. The indemnification
extends to any and all expenses (including but not limited to attorneys' fees
and costs, and any other out-of-pocket expense) and/or liabilities of any type
(including but not limited to judgments, fines, excise taxes or penalties under
the Employee Retirement Income Security Act ("ERISA"), and amounts paid in
settlement) reasonably incurred in connection with the investigation, defense,
settlement or appeal of such proceedings. The obligation to provide
indemnification does not apply if the indemnitee is adjudicated to be liable for
fraudulent or criminal conduct.
 
       The Company has purchased directors' and officers' liability insurance to
reimburse it for the costs incurred in connection with its indemnification
obligations described above. For the period from August 1996 to August 1997, the
period in which most of the claims against the Company and certain of its
directors and officers were asserted, the Company had in place three directors
and officers liability insurance policies (the "1996 and 1997 D&O Policies"),
each providing $5 million in coverage for an aggregate of $15 million. The
primary policy and first excess policy were issued by Lloyds of London. The
second excess policy was issued by Admiral Insurance Company. The insurance
carriers have taken the position that litigation filed after the policy periods
of the 1996 and 1997 D&O Policies but arising from the same facts and
circumstances as claims filed during the period from August 1996 to August 1997,
"relates back" to the 1996 and 1997 D&O Policies. Thus, the issuance carriers
assert that actions filed after August 1997 do not implicate coverage under the
Company's D&O insurance policies for the period August 1997 to August 1998 (the
"Current D&O Policies"). The Current D&O Policies provide aggregate coverage of
$20 million, subject to various exclusions, including claims relating to the
restatement of the
 
                                       14
<PAGE>
Company's financial statements. The 1996 and 1997 D&O Policies provide that 100
percent of the costs incurred in defending claims asserted jointly against the
Company and its current and former officers and directors are allocable to the
individuals' defense and, thus, are covered by the policy. However, the 1996 and
1997 D&O Policies do not provide any separate coverage for the Company.
Moreover, the Company does not have separate insurance to cover the costs of its
own defense or to cover any liability for any claims asserted against it. The
Company has not currently set aside any financial reserves relating to any of
the above-referenced actions.
 
    ILLUSTRA ESCROW
 
       In January 1997, pursuant to the Illustra Agreement, Informix made a
claim to certain shares held in an escrow fund. In response, the Illustra
shareholders have claimed that the Company wrongfully caused these shares to be
retained in escrow, thereby harming the Illustra shareholders. The Illustra
securities holders have filed a demand for arbitration with the private
arbitration service agreed upon by the parties to the Illustra Agreement;
however, at present, no litigation or arbitration proceedings have been
commenced with respect to the Illustra escrow. In March 1998, a complaint was
filed against the Company on behalf of former Illustra shareholders alleging
securities and common law fraud and misrepresentation causes of actions. See
"--Actions Arising Under Federal and State Securities Laws."
 
SECURITIES AND EXCHANGE COMMISSION INVESTIGATION
 
       In addition, in July 1997, the Securities and Exchange Commission issued
a formal order of investigation of the Company and certain unidentified
individuals associated with the Company with respect to non-specified accounting
matters, financial reports, other public disclosures and trading activity in the
Company's securities. The Company is cooperating with the investigation and is
providing all information subpoenaed by the Commission. The Company is in the
process of producing documents and a number of current and former officers have
been testified to appear before the Commission.
 
GENERAL
 
       The pending federal and state securities actions are in the early stages
of discovery. Consequently, at this time it is not reasonably possible to
estimate the damages, or the range of damages, that the Company might incur in
connection with such actions. However, the uncertainty associated with
substantial unresolved litigation can be expected to have an adverse impact on
the Company's business. In particular, such litigation could impair the
Company's relationships with existing customers and its ability to obtain new
customers. Defending such litigation will likely result in a diversion of
management's time and attention away from business operations, which could have
a material adverse effect on the Company's results of operations. Such
litigation may also have the effect of discouraging potential acquirors from
bidding for the Company or reduce the consideration such acquirors would
otherwise be willing to pay in connection with an acquisition.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
       The Company did not submit any matters to a vote of security holders
during the fourth quarter of fiscal 1997.

DIVIDEND POLICY
 
       The Company has never declared or paid cash dividends on its Common
Stock. The Company expects to retain future earnings, if any, for use in the
operation of its business and does not anticipate paying any cash dividends on
its Common Stock in the foreseeable future. The holders of the Company's Series
B Convertible Preferred Stock (the "Series B Preferred") are entitled to receive
a cumulative dividend at an annual rate of 5% of the face value of each share of
Series B Preferred, resulting in an aggregate annual dividend accrual of $2.5
million. As of December 31, 1997, aggregate accrued, but unpaid, dividends of
approximately $301,000 were owed to the holders of the Series B Preferred. The
dividend is generally payable upon the conversion or redemption of the Series B
Preferred and may be paid in cash or, at the Company's election and subject to
certain conditions, in shares of Common Stock. In addition, the Certificate of
Designation of the Series B Preferred prohibits the Company from paying any
dividend or other distribution on any security ranking junior to the Series B
Preferred. The Company's Series A-1 Convertible Preferred Stock (the "Series A-1
Preferred") is senior to the Series B Preferred. In the event the Company fails
to satisfy certain contractual obligations under the agreements pursuant to
which the Series A-1 Preferred was issued, the holders of the Series A-1
Preferred are entitled to a 15% annual dividend on the face value of each share
of Series A-1 Preferred which would, based on 160,000 shares of Series A-1
Preferred outstanding as of December 31, 1997, result in an aggregate annual
dividend of $6.0 million, payable quarterly in cash for so long as the Company
is in breach of such obligations. As of the date of this report, there were no
shares of Series A-1 Preferred outstanding. However, Fletcher International
Limited ("Fletcher") holds a presently exercisable warrant to purchase up to
80,000 shares of Series A-1 Preferred. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Recent Developments."

RECENT SALES OF UNREGISTERED SECURITIES
 
       The Company has issued and sold the following unregistered securities
during the period covered by this report which have not previously been reported
in the Company's quarterly reports on Form 10-Q:
 
       1.  On August 12, 1997, pursuant to a Subscription Agreement dated of
even date (the "Subscription Agreement"), the Company sold 160,000 shares of its
Series A Convertible Preferred Stock (the "Series A Preferred") for aggregate
gross proceeds of $40,000,000 to Fletcher. The Series A Preferred was
convertible into shares of Common Stock at any time after issuance and would
have automatically converted into Common Stock 18 months following the date of
its issuance by the Company. At the holder's option, each share of Series A
Preferred, which had a face value of $250, was convertible into Common Stock at
a per share price equal to 101% of the Common Stock average price for the 30
trading days ending five trading days prior to the conversion, but not greater
than the lesser of (i) 105% of the Common Stock average price of the first five
trading days of such 30 day period, or (ii) $12. The number of shares of Common
Stock to be issued upon conversion varied based on future stock price movements.
In connection with the sale of the Series A Preferred, the Company issued a
warrant to purchase up to 140,000 shares of its Series A Preferred (the "Series
A Warrant") to Fletcher with an aggregate purchase price of $35,000,000. The
Series A Warrant was generally exercisable from and after August 13, 1997 to and
including February 15, 1998, with a provision for extension of the warrant
exercise period under certain circumstances.
 
       2.  On November 17, 1997, pursuant to an amendment to the Subscription
Agreement, the Registrant issued 160,000 shares of its Series A-1 Preferred to
Fletcher in exchange for the cancellation of the Series A Preferred that had
been issued in August 1997. The Series A-1 Preferred is generally convertible
according to the same terms as the Series A Preferred described above. In
connection with the issuance of the Series A-1 Preferred, the Company issued a
warrant to purchase up to 140,000 shares of its Series A-1 Preferred to Fletcher
with an aggregate purchase price of $35,000,000 in exchange for the cancellation
of the Series A Warrant (the "Series A-1 Warrant"). The Series A-1 Warrant is
generally exercisable from its date of issuance until April 15, 1999, with a
provision for extension of the warrant exercise period under certain
circumstances.
 
       3.  On November 19, 1997, pursuant to a Securities Purchase Agreement
dated November 17, 1997, the Company sold 50,000 shares of newly authorized
Series B Preferred for aggregate gross proceeds of $50,000,000 to an investor
group led by an affiliate of Credit Suisse First Boston. Upon conversion of the
Series B Preferred, the Company is required to issue a warrant to acquire a
number of shares equal to 20% of the shares of Common Stock issued upon the
conversion of the Series B Preferred but no less than 1,500,000 shares, together
with an additional increment of warrants to purchase 200,000 shares of Common
Stock (collectively, the "Series B Warrants"). The Series B Warrants may be
exercised until 2002. In connection with the sale of the Series B Preferred, the
Company issued 100,000 shares of its Common Stock to The Shemano Group, a
financial advisor to the Company ("Shemano"). In addition, the Company agreed to
issue Shemano a warrant to purchase up to 50,000 shares of the Company's Common
Stock if the closing sales price of the Company's Common Stock as reported on
The Nasdaq Stock Market on May 17, 1998 does not exceed $12.50.
 
       4.  On February 13, 1998, Fletcher exercised the Series A-1 Warrant in
part and the Company issued 60,000 shares of Series A-1 Preferred (the "Series
A-1 Warrant Stock") to Fletcher for aggregate gross proceeds of $15.0 million.
In addition, pursuant to the Subscription Agreement, Fletcher converted 220,000
shares of Series A-1 Preferred into 12,769,908 shares of the Company's Common
Stock.
 
       The sales of the above securities were deemed to be exempt from
registration under the Securities Act in reliance on Regulation S under the
Securities Act, Section 4(2) of the Securities Act, Regulation D promulgated
thereunder or Section 3(a)(9) of the Securities Act as transactions by an issuer
not involving a public offering or as an exchange of securities of the Company
with existing security holders where no commission or other renumerator is paid
or given directly or indirectly for soliciting such exchange. The
 
                                       17
<PAGE>
recipients of securities in each such transaction represented their intention 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 and warrants issued in such transactions. All recipients
had adequate access, through their relationships with the Company, to
information about the Registrant.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
       THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF
SECTION 27A OF THE SECURITIES ACT OF 1933 AND SECTION 21E OF THE SECURITIES
EXCHANGE ACT OF 1934. THESE FORWARD-LOOKING STATEMENTS ARE SUBJECT TO CERTAIN
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY
FROM HISTORICAL RESULTS OR ANTICIPATED RESULTS, INCLUDING THOSE SET FORTH UNDER
"FACTORS THAT MAY AFFECT FUTURE RESULTS" IN THIS ITEM 7 AND ELSEWHERE IN, OR
INCORPORATED BY REFERENCE INTO, THIS REPORT.
 
OVERVIEW
 
       The Company is a leading multinational supplier of information management
software. It derives license revenues principally from licensing its RDBMS
software and derives service revenues from providing technical product support
and product updates and consulting and training services to customers. The
Company's products are sold directly to end-users and indirectly through
application resellers, OEM's and distributors.
 
       In the first quarter of fiscal 1997, the Company experienced a
substantial shortfall in license revenues compared to forecasts, resulting in a
substantial loss for that quarter. The shortfall in revenue was due to slow
growth in demand for RDBMS products as well as the Company's inability to close
a number of sales transactions that management anticipated would close by
quarter's end, particularly in Europe.
 
       As a result of the shortfall in license revenues for the first quarter of
fiscal 1997, the Company, in the second quarter and again in the third quarter
of fiscal 1997, initiated an internal restructuring of its operations intended
to reduce operating expenses and improve the Company's financial condition.
These restructurings included selective reductions in headcount and leased
facilities and the downsizing, elimination or conversion into solution labs of
the Company's planned Information Superstores. Costs associated with the
restructurings totaled approximately $108.2 million and had a material adverse
effect on the Company's results of operations for fiscal 1997. In addition, the
Company issued newly designated series of Preferred Stock in two financing
transactions which resulted in aggregate net proceeds of $87.6 million to the
Company (excluding a $1.0 million fee paid to a financial advisor of the Company
in connection with the sale of the Series B Preferred) and entered into a senior
secured credit facility agreement with available proceeds of up to $75.0
million, of which the Company was eligible to borrow $47.0 million at December
31, 1997, based on certain eligibility criteria. See "Recent Sales of
Unregistered Securities" and "--Liquidity and Capital Resources."
 
       In August 1997, the Company announced that it had become aware of errors
and irregularities that affected the timing and the dollar amount of reported
earned revenues from license transactions for all annual periods in the three
years ended December 31, 1996. These errors and irregularities included
unauthorized and undisclosed arrangements or agreements between Company
personnel and resellers, recognition of revenue on certain transactions in
reporting periods prior to contract acceptance, the recording of certain
transactions that lacked economic substance and the recording of maintenance
revenue as license revenue. The unauthorized and undisclosed agreements with
resellers introduced acceptance contingencies, permitted resellers to return
unsold licenses for refunds, extended payment terms or committed the Company to
assist resellers in selling the licenses to end-users. Accordingly, license
revenues from these transactions that were recorded at the time product was
delivered to resellers should have instead been recorded at the time all
conditions to the sale lapsed. Because of the pervasiveness of the unauthorized
arrangements with resellers in the 1994, 1995 and 1996 accounting periods, the
Company concluded that all revenue from license agreements with resellers,
except for those licenses sold and billed on a per copy basis, should be
recognized only when the licenses were resold or utilized by resellers and all
related obligations had been satisfied. In addition, amounts received from
resellers or financial institutions as prepayments of software license fees in
advance of revenue recognition should be recorded as advances
 
                                       19
<PAGE>
on unearned license revenue. The financial review undertaken by the Company
resulted in the restatement of the Company's financial results for fiscal 1996,
1995 and 1994 and for the first quarter of fiscal 1997. The Company publicly
disclosed the results of the restatement in November 1997.
 
       The nature of the Company's business in 1992 and 1993 was such that there
was not a material amount of revenues recorded under prepaid software license
transactions conducted with resellers during these years. Additionally, as a
result of the Company's extended procedures, there were no material errors or
irregularities identified affecting revenues recognized prior to the third
quarter of 1994. The Company concluded based on those circumstances that it was
not necessary to restate the financial statements for 1992 and 1993.
 
       In connection with the errors and irregularities discussed above, a
number of conditions which collectively represented a material weakness in the
Company's internal accounting controls were identified. These conditions
included a deterioration in the Company's accounting controls at corporate and
regional management levels, and a related failure to stress the importance of
these controls, an inappropriate level of influence, principally by the
Company's sales organization, over the revenue recognition process and an
apparent lack of clarity and consistent understanding within the Company
concerning the application of the Company's revenue recognition policies to
large, complex reseller license transactions. To address the material weakness
represented by these conditions, the Company is implementing a plan to
strengthen the Company's internal accounting controls. This plan includes
updating the Company's revenue recognition policies regarding accounting and
reporting for large, complex reseller license transactions, developing and
conducting educational programs to help implement such policies, changing the
Company's corporate and regional accounting and reporting structure and
re-establishing the internal audit function reporting to the Company's Board of
Directors.
 
       As a result of the restatement, total revenues were reduced from amounts
previously reported by $204.8 million from $939.3 million as originally reported
to $734.5 million, by $77.7 million from $714.2 million as originally reported
to $636.5 million, and by $18.1 million from $470.1 million as originally
reported to $452.0 million for fiscal 1996, 1995 and 1994, respectively. The
restatement also resulted in an increase in revenues of $16.2 million from
$133.7 million as originally reported to $149.9 million for the first quarter of
fiscal 1997. In addition, the restatement resulted in a reduction in net income
of $171.4 million from $97.8 million as originally reported to a loss of $73.6
million for fiscal 1996; a reduction in net income of $59.0 million from $97.6
million as originally reported to $38.6 million for fiscal 1995; and a reduction
in net income of $13.6 million from $61.9 million as originally reported to
$48.3 million for fiscal 1994. The restatement had a material adverse effect on
the Company's financial condition, most notably evidenced by substantial
reductions in retained earnings and working capital. At December 31, 1996, after
giving effect to the restatement, the Company's working capital decreased $255.3
million from $258.4 million as originally reported to $3.1 million. At December
31, 1997, the Company had a working capital deficit of $140.2 million. The
substantial reductions in working capital at December 31, 1997 and 1996 reflect
substantial operating losses and the addition of "advances from customers and
financial institutions" as a current liability on the Company's balance sheet.
Such advances totaled $180.0 million at December 31, 1997 and $239.5 million at
December 31, 1996.
 
       The Company's public announcement of the pending restatement, delays in
reporting operating results for the second and third quarters of fiscal 1997
while the restatement was being compiled, threatened de-listing of the Company's
Common Stock from the Nasdaq National Market as a result of the Company's
failure to satisfy its public reporting obligations, corporate actions to
restructure operations and reduce operating expenses, and customer uncertainty
regarding the Company's financial condition adversely affected the Company's
ability to sell its products in fiscal 1997. The financial restatement has now
been completed, its results have been publicly disclosed and the Company is
current with respect to its public reporting obligations. In addition, the
Company believes that it has effectively controlled its
 
                                       20
<PAGE>
operating expenses and significantly improved its financial condition.
Nevertheless, adverse market conditions, including significant competitive
pressures in the Company's markets and ongoing customer uncertainty about the
Company's financial condition and business prospects, may continue to have an
adverse effect on the Company's ability to sell its products and results of
operations.

       Informix's operating results for fiscal 1997 were significantly below the
prior year due to decreases in license revenue and increases in costs and
expenses. Revenue declined 10% for fiscal 1997 in comparison to fiscal 1996.
Revenue declined 9%, 7%, 10% and 2% in North America, Asia/Pacific, Europe and
Latin America, respectively. The increase in operating expenses reflects
continued expansion of product and customer support organizations through the
early months of fiscal 1997 as well as incremental legal and audit expenses
related to the stockholder lawsuits and the restatement process, charges of
$30.5 million related to the Company's Japanese operations, $108.2 million for
restructuring charges, $14.7 million for write-down to net realizable value of
previously capitalized software costs and $7.0 million for a write-off of
acquired research and development during the period. The lower revenues combined
with increased operating costs resulted in an operating loss of $355.7 million
for the year. See "Legal Proceedings," "--Cost of Software Distribution,"
"--Write-off of Acquired Research and Development," "--General and
Administrative Expenses" and "--Restructuring Charges."
 
       Informix's operating results were affected negatively in fiscal 1996 as a
result of operating expenses growing more rapidly than revenues. Informix
continued to invest heavily in personnel in the areas of sales, marketing and
customer service and research and development and incurred integration expenses
and fees associated with the acquisition in February 1996 of Illustra. In
December 1996, Informix
 
                                       21
<PAGE>
began shipping its Universal Server product. Informix incurred significant
marketing expenses in connection with the initial announcement and launch of the
Universal Server in fiscal 1996. These development,
integration and marketing expenses adversely affected Informix's operating
margins in fiscal 1996.
 
REVENUES
 
       The Company derives revenues from licensing its software and providing
post-license technical product support and updates to customers and from
consulting and training services. License revenues may involve the shipment of
product by the Company or the granting of a license to a customer to manufacture
products. Service revenues consist of customer telephone or direct support,
product update rights, consulting and training fees. Total net revenues were
$663.9 million, $734.5 million and $636.5 million for fiscal 1997, 1996 and
1995, respectively. Between December 31, 1996 and 1997, total net revenues
decreased by 10% or $70.6 million, primarily as a result of a substantial
decrease in license revenues, partially offset by an increase in service
revenues. Between December 31, 1995 and 1996, total net revenues increased by
15% or $98.0 million.
 
    LICENSE REVENUES
 
       The Company sells its products directly to end-users as well as through
resellers, including OEM's, distributors and VAR's. During fiscal 1996, the
Company increased the focus on its reseller channels to establish partnerships
with hardware and application vendors in order to utilize their sales force,
obtain access to their installed base of customers and benefit from their
consulting and systems integration organizations. The Company recognizes license
revenue from resellers, except for those sold and billed on a per copy basis,
when the licenses are resold or utilized by the reseller and all related
obligations have been satisfied. License revenues accounted for 57%, 68% and 73%
of total revenues in fiscal 1997, 1996 and 1995, respectively. The year-to-year
declines in license revenues as a percentage of total revenues reflect the fact
that service revenues have grown at a faster pace than license revenues, and
that license revenues declined substantially in fiscal 1997.
 
       License revenue declined by 25% to $378.2 million for fiscal 1997 from
$502.7 million for fiscal 1996. In the first quarter of fiscal 1997, license
revenues decreased 43% compared to the fourth quarter of fiscal 1996. This
decrease was primarily due to slow growth in demand for RDBMS products as well
as the Company's inability to close a number of sales transactions that
management anticipated would close by quarter's end, particularly in Europe. In
the second quarter of fiscal 1997, license revenue increased 26% compared to the
first quarter, principally as a result of stronger product license sales in
North America. In the third quarter of fiscal 1997, license revenues decreased
29% compared to the second quarter. The decrease in the third quarter was
attributable to a significant extent to decreased product license sales in
Europe and Latin America and customer uncertainties resulting from the Company's
announcement of the restatement of its financial statements in August 1997 and
restructuring activities in September 1997. During the fourth quarter of fiscal
1997, license revenues increased 36% as compared to the third quarter of fiscal
1997. The increase in the fourth quarter of fiscal 1997 was principally due to
increased license sales in Europe and Latin America, which the Company believes
was due to improved customer confidence about the Company and its financial
condition following the announcement of its restated financial statements.
 
       The Company does not believe that the decrease in license revenue in
fiscal 1997 compared to fiscal 1996 reflects a reduced acceptance of the
Company's products or a reduced competitive advantage of its products. The
Company believes that this decrease was primarily attributable to the slowing
growth in the market for RDBMS products and customer uncertainty about the
Company's financial condition and viability, due to the Company's operating
losses in the first three quarters of fiscal 1997, the announcement of the
restatement, the delays in reporting operating results for the second and third
quarters of fiscal 1997, the threatened de-listing of the Company's Common Stock
from the Nasdaq National Market as a result of the Company's failure to satisfy
its public reporting obligations, and the Company's actions to
 
                                       22
<PAGE>
restructure operations and reduce operating expenses. In addition, the Company
experienced a significant turnover in senior management sales positions during
1997, which adversely affected sales. During the fourth quarter of fiscal 1997,
the Company filled certain key sales positions through new hires, internal
promotion and reorganization of its sales force.
 
       License revenues increased 9% to $502.7 million for fiscal 1996 from
$462.1 million for fiscal 1995. The license revenue growth during fiscal 1996
reflects an increase in sales of the Company's server products, particularly the
Company's flagship database server, OnLine Dynamic Server, partially offset by a
decrease in license revenues from its database tool products. The increase in
server product revenues during fiscal 1996 reflected continued acceptance of the
Company's server products. The Company believes that the RDBMS industry has
benefited from market acceptance of UNIX, Windows, Windows NT and other open
operating environments and trends to downsize from large proprietary computer
systems. The Company believes that the decline in license revenues derived from
its database tool products is primarily the result of competitive product
offerings from other companies.
 
       At December 31, 1997, 1996 and 1995 licenses not resold by resellers
representing approximately $180.0 million, $239.5 million and $83.6 million,
respectively, were recorded as advances from customers and financial
institutions and had not been recognized as earned revenue. Licenses originally
recorded as advances from customers and financial institutions representing
approximately $64.8 million, $58.2 million and $34.2 million were sold through
reseller channels to end users during fiscal 1997, 1996 and 1995, respectively,
and recognized as earned revenue. The Company estimates that approximately $50
to $70 million of the advances from customers and financial institutions of
$180.0 million at December 31, 1997 will be sold through to end-users during
fiscal 1998. Nevertheless, there can be no assurances that such licenses will be
resold. If the underlying license agreements expire and are not renewed prior to
resellers' selling all licenses to end users and the Company has no remaining
obligations, the remaining revenue relating to customers' advances will be
recognized in the quarter following the expiration of the reseller license
agreements.
 
       The Company's license transactions can be relatively large in size and
difficult to forecast both in timing and dollar value. As a result, these
transactions have caused fluctuations in net revenues and net income (loss)
because of the relatively high gross margin on such revenues. As is common in
the industry, a disproportional amount of the Company's license revenue is
derived from transactions that close in the last weeks or days of a quarter. The
timing of closing large license agreements also increases the risk of
quarter-to-quarter fluctuations. The Company expects that these types of
transactions and the resulting fluctuations will continue.
 
       The Company is currently unable to forecast whether the decreases in
license revenue experienced in fiscal 1997 will continue in fiscal 1998. During
1997, substantial uncertainty existed about the Company's business and financial
condition. The Company believes that various actions taken by the Company during
1997 have substantially improved its financial condition. See "--Restructuring
Charges" and "--Liquidity and Capital Resources." Nevertheless, adverse market
conditions, including significant competive pressures and ongoing customer
uncertainty about the Company's financial condition and business prospects,
could continue to have an adverse effect on license revenues and results of
operations.
 
    SERVICE REVENUES
 
       Service revenues increased 23% to $285.7 million for fiscal 1997 from
$231.8 million for fiscal 1996. Service revenues increased 33% to $231.8 million
for fiscal 1996 from $174.5 million for fiscal 1995. Service revenues accounted
for 43%, 32% and 27% of total revenues in fiscal 1997, 1996 and 1995,
respectively. As the Company's products become more complex, more support
services are expected to be required. The Company intends to satisfy this
requirement through internal support, third-party services and OEM support.
Service revenues are comprised of maintenance, consulting and training revenues.
The Company continues to emphasize support services as a source of revenue and
the growth achieved in
 
                                       23
<PAGE>
absolute dollars reflects the growth in the Company's installed base and
strategic focus on providing consulting services for its customers. The
year-to-year increases in service revenues as a percentage of total revenues
reflect the fact that service revenues have continued to grow while license
revenues declined substantially in fiscal 1997.
 
       Revenue derived from post-contract technical support and fees for
software updates increased 18% to $188.1 million in fiscal 1997 from $159.5
million in fiscal 1996 and 31% in fiscal 1996 from $121.9 million in fiscal
1995. This increase is attributable principally to maintenance contracts for new
license sales in each year as well as the renewal of existing maintenance
contracts. In the event the Company continues to experience substantial declines
in license revenue, such declines would be expected to have an adverse effect on
growth in service revenues.
 
       Consulting and training revenues increased 35% to $97.6 million in fiscal
1997 from $72.3 million in fiscal 1996 and 38% in fiscal 1996 from $52.6 million
in fiscal 1995. The growth in the consulting and training practice was driven by
increased demand for consulting services primarily in North America and in
Europe. Some significant one-time large consulting contracts were also executed
in fiscal 1997 and contributed to the significant increase of consulting
revenues year over year. There can be no assurances that similar one-time large
consulting contracts will be entered into in future periods. Failure to secure
such contracts may have an adverse impact on the growth of service revenues.
 
    GEOGRAPHIC DISTRIBUTION
 
       The Company's distribution markets are organized into four general
markets: North America; Europe, the Middle East and Africa; Latin America; and
the Asia/Pacific region, including Japan. The North America, Europe, Latin
America and Asia/Pacific organizations contributed 46%, 34%, 8% and 12% of the
Company's net revenues, respectively, in fiscal 1997, compared to 46%, 34%, 7%
and 13%, respectively, in fiscal 1996 and 45%, 36%, 6% and 13%, respectively, in
fiscal 1995.
 
       Approximately 54%, 54% and 55% of Informix's net revenues were derived
from sales to foreign customers in fiscal 1997, 1996 and 1995, respectively.
Informix expects that foreign revenues will continue to provide a significant
portion of total revenues. However, changes in foreign currency exchange rates,
the condition of local economies, and the general volatility of software markets
may result in a higher or lower proportion of foreign revenues in the future. In
Europe and Asia/Pacific most revenues and expenses are now denominated in local
currencies. The U.S. dollar strengthened in fiscal 1997 against the major
European and Asia/Pacific currencies, which resulted in lower revenue and
expenses recorded when translated into U.S. dollars, compared with the prior
year periods. Although the Company has also increased its direct presence in
Latin America, a significant percentage of this region's revenue is still
denominated in U.S. dollars. Although the effect was not significant in fiscal
1997, the Company has in the past experienced significant currency fluctuations
in Mexico, and to a lesser extent, other Latin American countries, and expects
such fluctuations may occur in the future. The Company's operating and pricing
strategies take into account changes in exchange rates over time; however, the
Company's results of operations may be significantly affected in the short term
by fluctuations in foreign currency exchange rates. In addition, the current
continued weakness observed in Asian currencies may result in reduced revenues
from the countries affected by this condition, thus having a negative impact on
the overall performance of the Company.
 
    CONCURRENT TRANSACTIONS
 
       Principally during fiscal 1996, the Company entered into software license
agreements with certain computer and service vendors where the Company
concurrently committed to acquire goods and services. These concurrent
transactions in fiscal 1996 included license agreements of approximately $170.0
million and a commitment by the Company to acquire goods and services in the
aggregate of approximately $130.0 million. Concurrent transactions in 1997
included license agreements of approximately $21 million
 
                                       24
<PAGE>
and a commitment by the Company to acquire goods and services in the aggregate
of approximately $50 million. See Notes 1 and 2 of Notes to Consolidated
Financial Statements.

------------------------
 
N.M. = Not meaningful
 
       Cost of software distribution increased to $63.0 million for fiscal 1997
from $46.8 million and $37.6 million for fiscal 1996 and 1995, respectively.
Software distribution costs consist primarily of (i) manufacturing and related
costs such as media, documentation, product assembly and purchasing costs,
freight, customs, and third-party royalties and (ii) amortization of previously
capitalized software development costs including adjustments to the carrying
value of such capitalized costs based on changes to the Company's estimates of
the net realizable value of related products.
 
       Excluding amortization and the write-down to net realizable value of
previously capitalized software development costs, cost of software distribution
as a percentage of license revenue was 7% for fiscal 1997 and 6% for both fiscal
1996 and 1995. In the future, the cost of software distribution as a percentage
of revenue may vary depending upon the extent to which the product is reproduced
by the Company or by its customers.
 
       Amortization of capitalized software costs commences the quarter
following product introduction. Capitalized software amortization increased 47%
to $21.4 million for fiscal 1997 from $14.6 million for the prior year period.
The increase in amortization of capitalized software in absolute dollars and as
a percentage of net revenues is due to the release of the Company's Universal
Server products in the fourth quarter of fiscal 1996. The absolute value of
amortization of capitalized software will vary period to period as new products
are released and other products become fully amortized.
 
       Amortization of capitalized software increased 21% in fiscal 1996
compared to fiscal 1995 due to the release of several products in the latter
half of fiscal 1995 and 1996. The absolute value of amortization of capitalized
software will vary from quarter to quarter as new products are released and
other product development costs become fully amortized.
 
       The write-down to net realizable value of $14.7 million during the first
quarter of fiscal 1997 was due to the Company's acquisition of CenterView
Software, Inc. ("CenterView") and the related announcements of its revised tool
strategy. In accordance with Financial Accounting Standards Board Statement No.
86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," a net realizable value test was performed on certain of the
Company's database tool products and resulted in a write-down of $14.7 million
of previously capitalized software costs. In addition to this write-down, the
Company recorded separately a $7.0 million charge for write-off of Acquired
Research and Development in connection with the Company's acquisition of
CenterView. See "--Write-off of Acquired Research and Development."
 
                                       25
<PAGE>
COST OF SERVICES
 
       Cost of services consists primarily of maintenance, consulting and
training expenses. Cost of services increased 15% to $166.9 million for fiscal
1997 from $144.9 million for fiscal 1996. Cost of services increased 58% to
$144.9 million for fiscal 1996 from $91.5 million for fiscal 1995. The overall
growth in cost of services of 15% between fiscal 1996 and 1997 is consistent
with the 23% growth in service revenues over the same period. The cost of
services increased significantly in fiscal 1996 as the Company substantially
expanded its consulting practice in the United States and Europe as well as its
technical support organization in order to provide customer assistance for the
Online Dynamic Server product line. Cost of services decreased as a percentage
of service revenues to 58% for fiscal 1997 compared to 62% for the same period
in 1996. During fiscal 1997, gross margins increased relative to both support
revenue and consulting/training revenue, particularly in the third and fourth
quarters of that year. The Company believes that the increased margins during
fiscal 1997 were principally attributable to more efficient delivery of
services. The increase in cost of services in fiscal 1996 in absolute dollars
and as a percentage of net revenues compared to the prior year is primarily due
to the Company's expansion of consulting and support service capabilities as
products have become more complex.
 
SALES AND MARKETING EXPENSES
 
       Sales and marketing expenses increased less than 1% to $417.2 million for
fiscal 1997 from $413.7 million for fiscal 1996. Sales and marketing expenses
increased 37% to $413.7 million for fiscal 1996 from $301.9 million for fiscal
1995. As a percentage of revenues, sales and marketing expenses increased to 63%
in fiscal 1997 from 56% in fiscal 1996, due to a reduction in net revenues. As a
percentage of revenues, sales and marketing expenses increased to 56% in fiscal
1996 from 47% in fiscal 1995, due to significant increases in sales and
marketing personnel and marketing programs starting in late 1996.
 
       During the late months of fiscal 1996 and in the early months of fiscal
1997, there were significant increases in personnel and expenses as the Company
continued to expand its sales force for anticipated license revenue growth and
continued to implement various marketing programs, including its Information
Superstore program. The Information Superstore program, which was launched in
fiscal 1996 and through the early months of 1997, resulted in increased
depreciation expense due to the fixed asset purchases related to the program.
The slight increase in sales and marketing expense in fiscal 1997 in absolute
dollars compared to fiscal 1996 was a result of continued increased expenses in
the early months of fiscal 1997, offset by a significant reduction in overall
sales and marketing expenses in the second half of fiscal 1997 in connection
with the restructuring plan executed by the Company.
 
       Due to the significant revenue shortfall in the first quarter of fiscal
1997, the Company executed internal restructuring plans in the second quarter
and again in the third quarter, which included reducing headcount, consolidating
facilities and operations, and downsizing, eliminating or converting Information
Superstores into solution labs managed by the Company's consulting practice. The
Company had significantly lower sales and marketing costs in the fourth quarter
of fiscal 1997 as a result of these measures. In the fourth quarter of fiscal
1997, sales and marketing expenses were reduced to $69.3 million. Costs in the
fourth quarter of fiscal 1997 were 43% lower than the prior year quarter and 32%
lower than the third quarter of fiscal 1997.
 
       The significant increase in sales and marketing expenses in fiscal 1996
in absolute dollars compared to fiscal 1995 was a result of the addition of new
sales offices and sales personnel worldwide as the Company expanded its
worldwide sales organization, the opening of new foreign offices, higher
commission expense associated with the increase of revenues prior to the
restatement and increased marketing programs associated with new product
launches.

</TABLE>
 
       Research and development expenses increased 16% to $139.3 million for
fiscal 1997 from $120.2 million for fiscal 1996. Research and development
expenses increased 40% to $120.2 million for fiscal 1996 from $85.6 million for
fiscal 1996. The year-to-year increase in research and development expenses in
absolute dollars for fiscal 1997, is attributable principally to an increase in
staff which occurred during the early part of fiscal 1997, working on new
products and product extensions. The year-to-year increase in research and
development expenses in absolute dollars for fiscal 1996 is attributable
principally to an increase in staff working on the development of new products
and product extensions, including Universal Server.
 
       Informix accounts for its software development expenses in accordance
with Statement of Financial Accounting Standards No. 86, "Accounting for the
Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed." This
statement requires that, once technological feasibility of a developing product
has been established, all subsequent costs incurred in developing that product
to a commercially acceptable level be capitalized and amortized ratably over the
revenue life of the product.
 
       Prior to fiscal 1997, the higher capitalization in absolute dollars of
product development expenditures from year to year resulted from an increase in
the work involved in projects having already reached technological feasibility
as they neared their release dates, including Universal Data Options formerly
Informix Universal Server.
 
       The Company believes that research and development expenditures are
essential to maintaining its competitive position in its primary markets and
expects the expenditure levels to continue to constitute a significant
percentage of revenues.
 
GENERAL AND ADMINISTRATIVE EXPENSES
 
       In fiscal 1997, general and administrative expenses increased 36% to
$87.5 million from $64.4 million for fiscal 1996. In fiscal 1996, general and
administrative expenses increased 26% to $64.4 million from $51.1 million for
fiscal 1995. The increase in fiscal 1997 in general and administrative expenses
in absolute dollars and as a percentage of net revenue was primarily the result
of the continued expansion of the Company's international operations, higher bad
debt expense of $4.6 million, incremental legal and auditing expenses of $8
million resulting from the stockholders' litigation and the restatement of the
Company's financial statements, and the write-off of certain assets of $2.2
million. General and administrative expenses increased in absolute dollars in
1996 compared to 1995 as a result of the continued expansion of the Company's
international operations.
 
WRITE-OFF OF GOODWILL AND OTHER LONG-TERM ASSETS
 
       In accordance with Financial Accounting Standards Board Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of," the Company records impairment losses on long-lived
assets used in its operations when events and circumstances indicate that the
assets might be impaired and the estimated future undiscounted cash flows to be
generated by those assets are less than the assets' carrying amounts.
 
       In the first quarter of fiscal 1997, the Company's Japanese subsidiary
experienced a significant shortfall in business activity compared to historical
levels. This fact, coupled with continuing competitive
 
                                       27
<PAGE>
pressures in the Japanese market, resulted in the Company adjusting its
forecasts of the subsidiary's future cash flows and further led the Company to
evaluate the recoverability of the subsidiary's long-lived assets, including
computer and other equipment, acquired intangible assets and goodwill. As a
result of this evaluation, the Company determined that the carrying value of
these long-lived assets had been impaired and, accordingly, recorded a charge in
the first quarter of $30.5 million to write-down the assets' carrying value to
their estimated fair value. Fair value was determined using estimated future
discounted cash flows of the subsidiary and/or resale values as appropriate.
 
WRITE-OFF OF ACQUIRED RESEARCH AND DEVELOPMENT
 
       In February 1997, the Company acquired all of the outstanding capital
stock of CenterView, a privately owned corporation that provides software tools
for application development. The aggregate purchase price was approximately $8.7
million, which included cash plus direct costs of acquisition. For financial
statement purposes, the acquisition has been accounted for as a purchase and,
based on an independent appraisal of all the assets acquired and liabilities
assumed, the purchase price was allocated to the specifically identifiable
tangible and intangible assets acquired, including approximately $7.0 million of
purchased research and development which has been charged to operations in the
period the acquisition was consummated, the first quarter of fiscal 1997.
 
       Based on a review of CenterView's current suite of products, the
Company's management identified and classified future versions of the Company's
Data Director product as in-process technology, specifically Versions 3.0 and
4.0, as of the date of its acquisition. Data Director is an integrated
development extension for Microsoft Visual Basic that enables companies to build
corporate Intranet and client/server applications in a single environment. Data
Director enhances Visual Basic with a model-driven data access engine that
manages all database interactions between client and server, eliminating the
complexity traditionally associated with client/server development and enabling
companies to build client/ server applications faster and more efficiently than
with Visual Basic alone.
 
       Based on discussions with CenterView management, including project
development project managers regarding the stage of development of Versions 3.0
and 4.0, it was determined that these projects had not reached technological
feasibility as of the date of the CenterView acquisition, nor did these projects
have any alternative future use. This determination was based primarily on an
assessment of the history of the research and development schedules for the
projects, their current stage of development, the risks inherent in completing
the incremental research and development efforts necessary to reach
technological feasibility, and the planned general release dates. Version 3.0
was scheduled for first customer release in July 1997 while Version 4.0 was
anticipated to reach first customer release in April 1998. Based on the
discussions with CenterView management regarding historical product releases, it
was determined that commercial release occurs approximately two to three months
after first customer introduction of the product. The projects are expected to
produce positive levels of cash flow during the year ended December 31, 1998.
Moreover, the Company estimated that the costs to complete these projects would
be approximately $8.4 million in fiscal 1997 and approximately $4.2 million in
fiscal 1998. These figures were estimated by considering (i) the development
schedules of the in-process projects; (ii) complexity of the identified
development projects; and (iii) number of engineer hours per project, per year.
 
       The market for the Company's Data Director product is characterized by
rapidly changing technology, frequent new product introductions and evolving
market and customer demands. Although CenterView successfully developed and
marketed Data Director Version 2.1 and previous versions, there can be no
assurance that the Company will be successful in developing and marketing the
enhanced versions of the Data Director product. As such, the in-process
technology embedded in Data Director Versions 3.0 and 4.0 was valued utilizing
risk-adjusted cash flows to incorporate these and other uncertainties associated
with the Company's product development efforts. Failure to successfully complete
these
 
                                       28
<PAGE>
efforts in a timely manner could adversely affect the market potential for the
acquired CenterView products.
 
RESTRUCTURING CHARGES
 
       In June and again in September 1997, the Company approved plans to
restructure its operations in order to bring expenses in line with forecasted
revenues. In connection with these restructurings, the Company substantially
reduced its worldwide headcount and consolidated facilities and operations to
improve efficiency. The following analysis sets forth the significant components
of the restructuring reserve at December 31, 1997:

</TABLE>
 
       Severance and benefits represent the reduction of approximately 670
employees, primarily sales and marketing personnel, on a worldwide basis.
Temporary employees and contractors were also reduced. Write-off of assets
include the write-off or write-down in carrying value of equipment as a result
of the Company's decision to reduce the number of Information Superstores
throughout the world, as well as the write-off of equipment associated with
headcount reductions. The equipment subject to the write-offs and write-downs
consists primarily of computer servers, workstations, and personal computers
that will no longer be utilized in the Company's operations. These assets were
written down to their fair value less cost to sell. The carrying value at
December 31, 1997, of computer equipment included in the restructuring
activities during the second and third quarters of 1997 and intended to be
disposed of, is approximately $2.2 million. Facility charges include early
termination costs associated with the closing of certain domestic and
international sales offices.
 
       As a result of these restructuring activities, the Company was able to
reduce its operating expenses, in the form of lower depreciation expense,
reduced salaries and wages, and lower rent expense, by approximately $12.2
million and $19.7 million, respectively, in the third and fourth quarters of
1997 compared to quarterly expense levels incurred in 1997 prior to the
initiation of the restructuring activities.
 
       The total Restructuring Expense decreased by $1.2 million during the
fourth quarter of fiscal 1997 primarily due to adjusting the original estimate
of the loss to be incurred on the sale of land to the actual
loss.
 
       The Company expects to complete most of the actions associated with
restructuring by the end of the second quarter of fiscal 1998.
 
MERGER EXPENSES
 
       In the first quarter of fiscal 1996, the Company recorded expenses of
approximately $5.9 million as a result of the acquisition of Illustra, which was
accounted for as a pooling of interests. These costs consisted primarily of
investment banking, legal and accounting fees.
 
                                       29
<PAGE>
INTEREST INCOME
 
       Interest income was $5.6 million as compared to $9.9 million and $8.1
million for fiscal 1997, 1996 and 1995, respectively. The decline in fiscal 1997
in comparison to fiscal 1996 resulted from a reduction in the average
interest-bearing cash and short-term investments balances in fiscal 1997. The
reduction in cash is due to lower sales and higher expenses. The increase in
interest income from fiscal 1995 to fiscal 1996 was due to higher balances of
cash and cash equivalents and short-term investments, offset by slightly lower
interest rates.
 
INTEREST EXPENSE
 
       Interest expense decreased to $9.4 million from $12.5 million and
increased from $6.3 million for fiscal 1997, 1996 and 1995, respectively.
Interest expense principally relates to interest charges incurred in connection
with financing of customer accounts receivable and has decreased due to a
decrease in the amount of receivables financed.
 
OTHER INCOME, NET
 
       Other income, net, increased to $10.5 million for fiscal 1997 from $2.9
million and $0.1 million in fiscal 1996 and 1995, respectively. The increase
from fiscal 1996 was due primarily to $8.1 million of net gains on the sale of
marketable securities and $8.0 million of foreign currency transaction gains,
offset partially by adjustments of $4.5 million to the carrying value of
strategic investments and $1.1 million of other expenses. Other income, net, in
fiscal 1996 consisted of $3.9 million of gain on sale of marketable securities
offset by other net expenses of $1.0 million.
 
       The restatement of the 1996, 1995 and 1994 financial statements resulted
in a change in the Company's foreign currency denominated intercompany accounts
payable and accounts receivable balances. As a result, certain foreign currency
transaction gains and losses realized due to fluctuation in the related asset
and liability currency exchange rates were not offset by underlying gains and
losses on forward foreign currency exchange contracts used to hedge those
foreign currency exposures. The Company recorded net foreign currency
transaction gains of approximately $8.0 million, $.3 million and $.2 million in
fiscal 1997, 1996 and 1995, respectively; the restatement of the Company's
financial statements affected the recorded net foreign currency transaction
gains and (losses) as follows: $7.5 million, $(0.7) million, $0.1 million, and
$(0.5) million in fiscal 1997, 1996, 1995 and 1994, respectively.
 
INCOME TAXES
 
       In fiscal 1997, income tax expense resulted primarily from foreign
withholding taxes and taxable earnings in certain foreign jurisdictions. The
expected tax benefit computed by applying the federal statutory rate to the loss
before income taxes was substantially offset by a corresponding increase in the
valuation allowance for net deferred tax assets. The Company has provided a
valuation allowance for the net deferred tax assets in excess of amounts
recoverable through carryback of net operating losses. Accordingly, realization
of the net deferred tax asset at December 31, 1997 of $34 million is not
dependent on future taxable income.
 
       In fiscal 1996, income tax expense resulted from an increase in the
valuation allowance for deferred tax assets attributable to foreign net
operating loss carryforwards, foreign withholding taxes and taxable earnings in
certain foreign jurisdictions.

IMPACT OF RESTATEMENT ON QUARTERLY FINANCIAL INFORMATION
 
       The restatement of the financial statements for fiscal 1996, 1995 and
1994 and the first quarter of fiscal 1997 had the following impact on previously
reported quarterly financial information.

(1) The Company recorded in the second quarter and again in the third quarter of
    fiscal 1997, restructuring charges of $59.6 million and $49.7 million,
    respectively. The total restructuring expenses decreased by $1.2 million
    during the fourth quarter of fiscal 1997 primarily due to adjusting the
    original estimate of the loss to be incurred on the sale of land to the
    actual loss. (See Note 13 to the Consolidated Financial Statements)
 
(2) In the first quarter of fiscal 1997, the Company recorded a charge of $30.5
    million to write down the carrying values of certain of its Japanese
    subsidiary's long-lived assets to their fair values. During the same
    quarter, the Company also recorded a charge of $14.7 million to write down
    the carrying value of capitalized software development costs for certain
    products to their net realizable values.

    OPERATING CASH FLOWS
 
       Cash used by operations increased significantly to $144.8 million for the
year ended December 31, 1997 from $29.4 million in 1996 due to operating
expenses in excess of revenues. Cash from operations did not provide sufficient
resources to fund the Company's operations in fiscal 1997 and 1996.
 
       The net loss of $356.9 million for fiscal 1997, included a number of
non-cash transactions. These non-cash transactions included write-downs of long
term assets, capitalized software, goodwill and acquired research and
development and certain non-cash restructuring charges which partially offset
the net loss resulting in net cash used by operations of $144.8 million.
 
       Net accounts receivable decreased by $52.5 million to $142.0 million as
of December 31, 1997 from December 31, 1996. This decrease resulted from a $35.7
million decrease in revenues during the fourth quarter of fiscal 1997 as
compared to the fourth quarter of fiscal 1996 partially offset by a reduction in
its financing programs with third-party financial institutions in fiscal 1997.
Days sales outstanding ("DSO") was 71, 83 and 79 at December 31, 1997, 1996 and
1995, respectively. The Company increased its efforts to improve cash
collections in fiscal 1997 in response to its deteriorating cash position during
the year. The Company expects DSO in 1998 to approximate or to slightly increase
from the fiscal 1997 levels. Cash received from customers and third-party
financial institutions in advance of revenue being recognized is recorded as
advances on unearned license revenue.
 
    INVESTING CASH FLOWS
 
       Net cash and cash equivalents used in investing activities decreased for
the year ended December 31, 1997 compared with the same period in 1996. The
decrease was due in large part to lower investments of excess cash due to the
significant decline in cash balances over the year. Significant investing
activities, excluding the investment of excess cash, during the year included
additions to software costs of $20.8 million, the sale of available-for-sale
securities for $46.0 million, purchase of the Santa Clara property and capital
equipment of $92.2 million, the purchase of CenterView for $8.7 million and net
proceeds from selling the Santa Clara property of $59.3 million.
 
       The Company sold its interest in a strategic investment during fiscal
1997 which resulted in net proceeds of $10.4 million.
 
       The Company planned on relocating its corporate headquarters to Santa
Clara, California, approximately 15 miles to the south of the Company's
headquarters. In January 1997, the Company entered into a two year lease for 27
acres of undeveloped commercial real estate which required a pledge of $61.5
million in cash into a non-interest bearing collateral account controlled by an
affiliate of the lessor. In April 1997, the Company exercised its option to
purchase the land for $61.5 million with the intent to arrange for the sale of
the parcels to unrelated third parties. The $61.5 million is reflected in the
"purchases of land and property and equipment" line of the cash flow statement.
The land sales closed in the fourth quarter of fiscal 1997, and $59.3 million is
disclosed on the "proceeds from disposal of land and property and equipment."
 
                                       32

       In addition, during fiscal 1997, the Company acquired $30.7 million of
capital equipment consisting primarily of computer equipment, computer software
and office equipment. Capital equipment purchases were primarily the result of
the Company's expected expansion during the first half of fiscal 1997.
 
       In February 1997, the Company acquired all of the outstanding capital
stock of Centerview, a privately owned corporation that provides software tools
for application development. The aggregate purchase price was approximately $8.7
million, which included cash plus direct costs of acquisition. For financial
statement purposes, the acquisition has been accounted for as a purchase and,
based on an independent appraisal of all the assets acquired and liabilities
assumed, the purchase price was allocated to the specifically identifiable
intangible assets acquired, including approximately $7.0 million of purchased
research and development which has been charged to operations in the period the
acquisition was consummated the first quarter of fiscal 1997.
 
    FINANCING
 
       Net cash and cash equivalents provided by financing activities in fiscal
1997 decreased in comparison to the same period in 1996. A significant portion
of the decrease was the decline in advances from customers and financial
institutions, partially offset by the proceeds from issuances of preferred and
common stock.
 
       The Company may receive cash, either from the customer, or from a
financial institution to whom the customer payment streams due under software
license arrangements are sold, prior to the time the license fee is recognized
as earned revenue. If the Company fails to comply with the contractual terms of
the specific license agreement, the Company could be required to refund to the
customer or the financial institution the amount(s) received. However, the
Company does not believe the refunds of amounts received, if any, will have a
material effect on the Company's results of operations, financial position, or
cash flows. During fiscal 1997, 1996 and 1995, the Company received $21.8
million, $207.2 million and $109.3 million respectively, of license fee payments
in advance of revenue being recognized under such transactions.
 
       Proceeds from common stock represent stock options exercised and
purchases under the employee stock purchase plan. In September 1997, the
Company's Board of Directors authorized the repricing of outstanding stock
options to purchase Common Stock under the Company's stock option plans so that
the exercise price of repriced options would equal the closing sales price of
the Company's Common Stock as reported on The Nasdaq Stock Market on November
17, 1997, which was $7.1563. See "Executive Compensation--Stock Option
Repricing."
 
       In August 1997, the Company raised net proceeds of $37.6 million through
the issuance of the Series A Preferred. In November 1997, the Company raised an
additional $50.0 million in net proceeds (excluding a $1.0 million fee paid to a
financial advisor of the Company) through the issuance of the Series B
Preferred. Simultaneously with the closing of the Series B Preferred, the
holders of the Series A Preferred exchanged all their outstanding shares of
Series A Preferred for the newly designated Series A-1 Preferred, having
substantially similar rights, preferences and privileges as the Series A
Preferred with the exception of certain amendments, including revisions to the
terms under which such shares become mandatorily redeemable.
 
       The Company assigned its leasehold interest and its related obligations
under an office space lease in Santa Clara, California to an unrelated third
party. The lease term was for fifteen years and minimum lease payments amount to
$96.0 million over the term. The Company remains contingently liable for minimum
lease payments under the terms of the assignment.
 
       As of December 31, 1997, the Company was contractually obligated to
purchase approximately $4.4 million of various computer equipment.
 
                                       33
<PAGE>
       The Company has several active software development and service provider
contracts with third-party technology providers. These agreements contain
financial commitments by the Company of $15.1 million, $11.4 million, $10.4
million, $7.3 million and $3.5 million in fiscal 1998, 1999, 2000, 2001 and
2002, respectively.
 
       In December 1997, Informix Software, Inc., a Delaware corporation and the
Company's principal operating subsidiary ("Informix Software"), entered into a
Senior Secured Credit Agreement with a syndicate of commercial banks, including
BankBoston, N.A. as administrative agent and Canadian Imperial Bank of
Commercial as syndication agent, providing for a revolving credit facility of up
to $75 million (the "Credit Facility"). The actual amount available under the
Credit Facility, for either direct borrowings or issuances of letters of credit,
is based on 80% of the eligible domestic accounts receivable and 50% of the
eligible foreign accounts receivable. Accounts receivable for an account debtor
are ineligible for purposes of the Credit Facility when (a) such account
receivable is outstanding for longer than 60 days, (b) the account debtor or any
other person obligated to make payment thereon asserts any defense, offset,
counterclaim or other right to avoid or reduce the amount of the account
receivable, but only to the extent the lenders reasonably determine a valid
defense, offset, counterclaim or other right exists and then only to the extent
of such right, (c) the account debtor or other person required to make payment
thereon is insolvent, subject to bankruptcy or receivership proceedings or has
made an assignment for the benefit of creditors or whose credit standing is
unacceptable to the lenders, and the lenders have so notified the Company (d)
the account debtor is a lender under the Credit Facility, (e) 30% or more of the
accounts receivable of any account debtor is deemed ineligible because such
accounts are outstanding for longer than 60 days thus rendering all the accounts
receivable of that debtor ineligible, and (f) the lender reasonably deems not to
qualify an account receivable as eligible and provides a reasonably detailed
written explanation to the Company. Under the Credit Facility, foreign accounts
receivable that are backed by a letter of credit issued or confirmed by a
financial institution approved by the lenders are deemed to be domestic accounts
receivable. As a result, the aggregate amount available under the Credit
Facility will vary from time to time based on the amount and eligibility of the
Company's receivables. As of December 31, 1997, no borrowings were outstanding
under the Credit Facility, the Company's accounts receivable totaled $142
million and its borrowing base under the Credit Facility was $47 million.
 
       The purpose of the Credit Facility is to provide the Company working
capital and finance general corporate purposes. The term of the Credit Facility
is two years. Amounts outstanding under the Credit Facility bear interest at a
premium over one of two alternative variable rates selected by the Company. The
"Base Rate" equals the greater of (i) the rate of interest announced by
BankBoston, N.A. as its "base rate" and (ii) the Federal Funds Effective Rate
plus 1/2 of 1% per year. The "Adjusted LIBOR Rate" equals (i) the London
Interbank Offered Rate divided by (ii) one minus the applicable reserve
requirement under Regulation D of the Federal Reserve Board. The maximum premium
over the Base Rate is 1.25%, and the maximum premium over the LIBOR Rate is
2.50%, subject to downward adjustment based on the Company's realizing certain
financial thresholds. The Credit Facility is secured by all of the assets of
Informix Software and the capital stock of the Company's subsidiaries that are
domiciled in the United States, including Informix Software. The availability of
the Credit Facility is also subject to the Company's compliance with certain
covenants, including the following financial covenants requiring the Company to:
(a) maintain a ratio of 1.25 to 1.00 in respect of the sum of cash and acounts
receivable to the difference of current liabilities less deferred and unearned
revenues, (b) maintain quarterly revenues of $150.0 million through June 1998
and $160.0 million thereafter, (c) maintain quarterly operating loss of no more
than $10.0 million through the quarter ending March 31, 1998 and a quarterly
operating profit of at least $10 million for the quarter ending June 30, 1998
and a quarterly operating profit of at least $15 million thereafter. (d)
maintain, for the quarter ending June 30, 1998 and each quarter thereafter, a
positive quarterly cash flow consisting of operating income which does not
include any restated revenue resulting from the Company's November 1997
restatement of its financial statements, capitalized software costs, capital
expenditures or cash outlays in respect of accrued expenses arising from
restructuring charges (but which income figure does take into account
depreciation and amortization expenses), (e) maintain an
 
                                       34
<PAGE>
interest coverage ratio of 1.25 to 1.00 in respect of quarterly operating cash
flow to interest expense plus scheduled amortization of debt, (f) refrain from
making additional investments in fixed or capital assets, in any fiscal year, in
excess of $15.0 million, plus any carry forward amount which amount cannot
exceed $5.0 million, and (g) refrain from entering into any merger,
consolidation, reorganization or other transaction resulting in a fundamental
change. At December 31, 1997, the Company was in compliance with all financial
covenants under the Credit Facility.
 
DISCLOSURES ABOUT MARKET RATE RISK
 
    INTEREST RATE RISK.  The Company's exposure to market rate risk for changes
in interest rates relates primarily to the Company's investment portfolio. The
Company does not use derivative financial instruments in its investment
portfolio. The Company places its investments with high quality issuers and, by
policy, limits the amount of credit exposure to any one issuer. The Company is
averse to principal loss and ensures the safety and preservation of its invested
funds by limiting default, market and reinvestment risk. The Company classifies
its cash equivalents and short-term investments as "fixed rate" if the rate of
return on such instruments remains fixed over their term. These "fixed-rate"
investments include fixed rate U.S. government securities, municipal bonds, time
deposits and certificates of deposits. The Company classifies its cash
equivalents and short-term investments as "variable rate" if the rate of return
on such investments varies based on the change in a predetermined index or set
of indices during their term. These "variable-rate" investments primarily
include money market accounts held at various securities brokers and banks. The
table below presents the amounts and related weighted interest rates of the
Company's investment portfolio at December 31, 1997:

    FOREIGN CURRENCY RISK.  The Company enters into forward foreign exchange
contracts primarily to hedge the value of accounts receivable or accounts
payable denominated in foreign currencies (mainly European and Asian foreign
currencies) against fluctuations in exchange rates until such receivables are
collected or such payables are disbursed. The Company does not enter into
forward foreign exchange contracts for speculative or trading purposes. The
Company's accounting policies for these contracts are based on the Company's
designation of the contracts as hedging transactions. The criteria the Company
uses for designating a contract as a hedge include the contract's effectiveness
in risk reduction and one-to-one matching of derivative instruments to
underlying transactions. Gains and losses on forward foreign exchange contracts
are deferred and recognized in income in the same period as losses and gains on
the underlying transactions are recognized and generally offset. If an
underlying hedged transaction is terminated earlier than initially anticipated,
the offsetting gain or loss on the related forward foreign exchange contract
would be recognized in income in the same period. Subsequent gains or losses on
the related contract would be recognized in income in each period until the
contract matures, is terminated or sold. The Company operates in certain
countries in Latin America, Eastern Europe and Asia Pacific where there are
limited forward currency exchange markets and thus the Company has unhedged
transaction exposures in these currencies. However, such exposures are not
material to the Company's financial statements for any period presented. In
addition, since the Company enters into forward contracts only as a hedge, any
change in currency rates would not result in any material net gain or loss as
any gain or loss on the underlying foreign currency denominated balance would be
offset by the gain or loss on the forward contract. The table below provides
information about the Company's foreign currency forward exchange contracts. The
information is provided in U.S. dollar equivalents and presents the notional
amount (contract amount) and the weighted average contractual foreign currency
exchange rates. All contracts mature within twelve months.

    SUMMARY
 
       The Company believes that its current cash balances, cash available under
the Credit Facility and cash flow from operations will be sufficient to meet its
working capital requirements for at least the next 12 months.
 
RECENT DEVELOPMENTS
 
       On February 13, 1998, Fletcher exercised the Series A-1 Warrant in part,
and the Company issued 60,000 shares of Series A-1 Preferred to Fletcher for net
proceeds of $14.1 million. The sale of the Series A-1 Warrant Stock was not
registered under the Securities Act pursuant to the exemption provided by
Regulation S.
 
       On February 13, 1998, pursuant to the Subscription Agreement, Fletcher
converted 220,000 shares of Series A-1 Preferred into 12,769,908 shares of the
Company's Common Stock.
 
       In December 1997, the Company's Board of Directors authorized a second
option repricing of outstanding stock options under the Company's stock option
plans so that the exercise price of the repriced options would equal the closing
sales price of the Company's Common Stock as reported on The Nasdaq Stock Market
on January 9, 1998, $5.094. See "Executive Compensation--Stock Option
Repricing."
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
       In 1997, the American Institute of Certified Public Accountants issued
Statement of Position 97-2 (SOP 97-2), "Software Revenue Recognition" as amended
by Statement of Position 98-4 (SOP 98-4). The Company will be required to adopt
the provisions of the SOPs' as of January 1, 1998. The adoption may, in certain
circumstances, result in the deferral of software license revenues that would
have been recognized upon delivery of the related software under preceding
accounting standards. In response to these SOPs', the Company will likely change
its business practices and, consequently, the Company cannot quantify the effect
the SOPs' will have on its operating results, financial position or cash flows.

       In June 1997, the Financial Accounting Standards Board issued Statement
No. 130, Reporting Comprehensive Income (FAS No. 130) and Statement No. 131,
Disclosures About Segments of An Enterprise and Related Information (FAS No.
131). FAS No. 130 establishes rules for reporting and displaying comprehensive
income. FAS No. 131 will require the Company to use the "management approach" in
disclosing segment information. Both statements are effective for the Company
during 1998. The Company does not believe that the adoption of either FAS No.
130 or FAS No. 131 will have a material impact on the Company's results of
operations, financial position or cash flows.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
       THIS REPORT, INCLUDING THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS, CONTAINS FORWARD-LOOKING
STATEMENTS AND OTHER PROSPECTIVE INFORMATION RELATING TO FUTURE EVENTS. THESE
FORWARD-LOOKING STATEMENTS AND OTHER INFORMATION ARE SUBJECT TO CERTAIN RISKS
AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM
HISTORICAL RESULTS OR ANTICIPATED RESULTS, INCLUDING THE FOLLOWING:
 
UNCERTAIN IMPACT OF RESTATEMENT OF FINANCIAL STATEMENTS
 
       Subsequent to the filing with the Commission of its Quarterly Report on
Form 10-Q for the quarter ended March 30, 1997, the Company became aware of
errors and irregularities that affected the timing and dollar amount of reported
earned revenues from license transactions for all annual periods in the three
years ended December 31, 1996, in particular transactions involving unauthorized
or undisclosed arrangements or agreements with resellers. As a result of its
investigation into these errors and irregularities, in August 1997, the Company
announced that it would restate its financial results for fiscal 1996 and 1995.
The financial review undertaken by the Company to determine the extent of the
restatement ultimately resulted in the restatement of the Company's financial
results for fiscal 1996, 1995 and 1994 and for the first quarter of fiscal 1997.
The Company publicly disclosed the results of the restatement in November 1997.
The restatement had a material adverse effect on the Company's financial
condition, most notably evidenced by substantial reductions in retained earnings
and working capital. For a description of the errors and irregularities
identified and the impact of the restatement on the Company's reported revenues
and net income for fiscal 1996, 1995 and 1994 and the first quarter of fiscal
1997, see "--Working Capital Deficit" and "Management's Discussion and Analysis
of Financial Condition and Result of Operations."
 
       In connection with the errors and irregularities discussed above, a
number of conditions which collectively represented a material weakness in the
Company's internal accounting controls were identified. These conditions
included a deterioration in the Company's accounting controls at corporate and
regional management levels, and a related failure to stress the importance of
these controls, an inappropriate level of influence, principally by the
Company's sales organization, over the revenue recognition process and an
apparent lack of clarity and consistent understanding within the Company
concerning the application of the Company's revenue recognition policies to
large, complex reseller license transactions. To address the material weakness
represented by these conditions, the Company is adopting a plan to strengthen
the Company's internal accounting controls. This plan includes updating the
Company's revenue recognition policies regarding accounting and reporting for
large, complex reseller license transactions, developing and conducting
educational programs to help implement such policies, changing the Company's
corporate and regional accounting and reporting structure, and re-establishing
the internal audit function reporting to the Company's Board of Directors. Such
implementation is expected to require substantial management attention. See
"--Dependence on Key Personnel; Personnel Changes; Ability to Recruit
Personnel."
 
       The Company's public announcement in August 1997 of the pending
restatement, delays in reporting operating results for the second and third
quarters of fiscal 1997 while the restatement was being compiled, threatened
de-listing of the Company's Common Stock from the Nasdaq National Market as a
result of the Company's failure to satisfy its public reporting obligations,
corporate actions to restructure operations and reduce operating expenses, and
customer uncertainty regarding the Company's financial
 
                                       37
<PAGE>
condition adversely affected the Company's ability to sell its products in
fiscal 1997. In addition, since the beginning of 1997, the Company and its
competitors in the RDBMS industry have experienced substantially slower growth
in the market for RDBMS products. The financial restatement has now been
completed, its results have been publicly disclosed, and the Company is current
with respect to its public reporting obligations. In addition, the Company
believes that it has effectively controlled its operating expenses and
significantly improved its financial condition. Nevertheless, adverse market
conditions, including significant competitive pressures in the Company's markets
and ongoing customer uncertainty about the Company's financial condition and
business prospects, may continue to have an adverse effect on the Company's
ability to sell its products and results of operations. See "--Fluctuations in
Quarterly Results; Seasonality."
 
NEED FOR ADDITIONAL FINANCING; CUSTOMER FINANCING
 
       During fiscal 1997, the Company experienced substantial short-term
liquidity problems as its cash, cash equivalents and short term investments
declined to a quarter-end low of $104.4 million at June 29, 1997 from $261.0
million at December 31, 1996. The Company raised net proceeds of $37.6 million
in August 1997 and $50.0 million (excluding a $1.0 million fee paid to a
financial advisor of the Company) in November 1997 in separate financing
transactions in which the Company issued newly authorized series of convertible
Preferred Stock. In the fourth quarter of 1997, the Company raised aggregate net
proceeds of $59.3 million through the sale of real property it had purchased
earlier in the year. As a result of such financing activities during the second
half of 1997, the Company's cash, cash equivalents and short term investments
increased to $155.5 million at December 31, 1997. In addition, in the first
quarter of fiscal 1998, the Company raised aggregate net proceeds of $14.1
million in connection with the exercise of a warrant to acquire additional
shares of the Company's convertible Preferred Stock. The Company believes that
these actions have substantially improved its financial condition since early
1997. Nevertheless, adverse market conditions, including continued slower growth
rates in the markets for RDBMS products or on-going customer uncertainty about
the Company's financial condition and business prospects, could continue to have
an adverse effect on license revenues and results of operations. In addition,
recent instability in the Asian-Pacific economies and financial markets, which
accounted for approximately 12% and 13% of the Company's total revenues for the
years ended December 31, 1997 and 1996, respectively, has created further
uncertainty concerning the Company's revenues, cash flows and results of
operations.
 
       In December 1997, Informix Software entered into the Credit Facility
providing for a revolving credit line of up to $75 million. The actual amount
available under the Credit Facility, for either direct borrowings or issuances
of letters of credit, is based on 80 percent of the eligible domestic accounts
receivable and 50 percent of the eligible foreign accounts receivable. As of
December 31, 1997, no borrowings were outstanding under the Credit Facility, the
Company's accounts receivable totaled $142 million and its borrowing base under
the Credit Facility was $47 million. The purpose of the Credit Facility is to
provide the Company working capital and finance general corporate purposes. The
term of the Credit Facility is two years. Amounts outstanding under the Credit
Facility bear interest at a premium over one of two alternative variable rates
selected by the Company. The Credit Facility is secured by all of the assets of
Informix Software and the capital stock of the Company's subsidiaries that are
domiciled in the United States, including Informix Software. The availability of
the Credit Facility is also subject to the Company's compliance with certain
financial covenants. For a description of the accounts receivable eligibility
criteria, the alternative variable interest rates and the financial covenants
associated with the Credit Facility, see "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
       There can be no assurance that amounts raised in connection with the
Preferred Stock financing and real property sales transactions described above
and amounts available under the Credit Facility will be sufficient to cover the
Company's working capital needs or that the Company will not require additional
debt or equity financing in the future. In addition, there can be no assurance
that additional debt or equity financing will be available, if and when needed
or that, if available, such financing could be completed on
 
                                       38
<PAGE>
commercially favorable terms. Failure to obtain additional financing, if and
when needed, could have a material adverse effect on the Company's business,
results of operations and financial condition. To the extent the terms of any
available financing are materially unfavorable to the Company, such a financing
could impair the Company's ability to obtain additional financing in the future,
to implement its business plan, or to engage in various corporate transactions,
including potential acquisitions of the Company. See "--Working Capital
Deficit," "--Risks Associated with Preferred Stock Financings" and
"--Antitakeover Protections."
 
       In the normal course of its business, the Company arranges for
non-recourse financing through the sale of customer accounts receivable to
third-party financial institutions. The Company has traditionally relied on a
limited number of financial institutions for most of the customer financings it
arranges. The terms of the Credit Facility prevent the Company from selling
accounts receivable with an aggregate face value in excess of $20 million during
any twelve month period. See "--Working Capital Deficit" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
WORKING CAPITAL DEFICIT
 
       The restatement of the Company's financial statements has had a material
adverse effect on the Company's financial condition, most notably evidenced by
substantial reductions in retained earnings and working capital. At December 31,
1996, after giving effect to the restatement, the Company's working capital
totaled $3.1 million, compared to $258.4 million as originally reported. At
December 31, 1997, the Company had a working capital deficit of $140.2 million.
The substantial reduction in working capital, as restated, at December 31, 1996
reflects net losses in fiscal 1996 of $73.6 million and the addition of $239.5
million of "advances from customers and financial institutions" as a current
liability on the Company's balance sheet. The working capital deficit at
December 31, 1997 reflects net losses of $356.9 million for the year ended
December 31, 1997, $180.0 million in advances on unearned license revenue as of
such date, and substantial uses of cash as a result of the Company's internal
restructuring, which commenced in the second quarter of fiscal 1997.
 
       "Advances from customers and financial institutions" reflects amounts
previously received from customers or in connection with accounts receivable
financing transactions with third party financial institutions in advance of
revenue being recognized. Prior to the restatement, these amounts were
improperly recognized as earned but have now been designated as advances. A
substantial majority of such revenues arose in connection with license
agreements between the Company and OEMs, distributors and other resellers. In
connection with the review of its historical financial results, the Company
determined that sufficient post-contractual contingencies existed in connection
with certain reseller license arrangements so as to preclude recognizing
revenue. In addition, the Company concluded that informal or otherwise
undisclosed arrangements with a number of resellers have resulted or could
result in significant concessions or allowances that were not accounted for when
revenue was originally reported as earned. Although the Company's license
agreements provide for a non-refundable fee payable by the customer in single or
multiple installments at the beginning or over the term of the license
arrangements, amounts received by the Company under its license agreements could
be subject to refund in the event the Company fails to satisfy certain
post-signing obligations. At December 31, 1997 approximately $23 million of such
amounts received from customers were subject to commercial disputes, several of
which have proceeded to litigation. Of the $23 million subject to commercial
disputes, $6.0 million has been reflected on the balance sheet as accrued
expenses, and the Company believes that the remainder is properly booked as
advances from customers and financial institutions as the Company believes the
likelihood of refund is remote. Any such refunds, were they to occur, would not
have a material effect on the Company's results of operations as revenue has not
been recognized on such transactions.
 
       The Company has abandoned its plans to construct a new headquarters
facility and in December 1997 sold the real property it had purchased earlier in
the year, raising aggregate net proceeds of approximately $59.3 million. In
August 1997 and November 1997, the Company sold and issued newly designated
series of Preferred Stock in two separate financing transactions, raising net
proceeds of
 
                                       39
<PAGE>
approximately $87.6 million (excluding of a $1.0 million fee paid to a financial
advisor of the Company in connection with the sale of the Series B Preferred).
In addition, in the fourth quarter of 1997, the Company entered into the Credit
Facility. The term of the Credit Facility is two years. Although these financing
transactions have improved the Company's working capital position, in the event
the Company continues to maintain a substantial working capital deficit, such a
deficit could materially impair the Company's ability to sell its products as a
result of customer uncertainty about the Company's financial condition. See
"--Uncertain Impact of Restatement of Financial Statements," "--Need for
Additional Financing; Customer Financing" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
FLUCTUATIONS IN QUARTERLY RESULTS; SEASONALITY
 
       The Company's quarterly operating results have varied significantly in
the past and may vary significantly in the future depending upon a number of
factors, many of which are beyond the Company's control. These factors include,
among others, (i) customer uncertainty about the Company's financial condition
and business prospects, (ii) market demand for the Company's software, including
changes in industry growth rates for the Company's products, (iii) changes in
pricing policies by the Company or its competitors, including aggressive price
discounting to encourage volume purchase by customers, (iv) the size, timing and
contractual terms of significant orders, the effect of which may be exacerbated
by aggressive price discounting, (v) the timing of the introduction of new
products or product enhancements by the Company or its competitors, (vi)
budgeting cycles of customers and potential customers, (vii) changes in the mix
of revenues attributable to domestic and international sales, and (viii)
seasonal trends in technology purchases and other general economic conditions.
In particular, the Company's quarterly results may be adversely affected by the
industry's historical practice of aggressively discounting the price of its
products to encourage volume purchasing by customers. In the event the Company
experiences substantial pricing pressure with respect to one or more large
transactions in any given quarter, such pressure could result in a substantial
shortfall in revenues. The Company has operated historically with little or no
backlog and has generally recognized a substantial portion of its revenues in
the last weeks or days of a quarter. As a result, license revenues in any
quarter are substantially dependent on orders booked and shipped in the last
weeks or days of that quarter. In addition, the sales cycle for the Company's
products is relatively long and may vary depending on a number of factors,
including the size of the transaction and the level of competition the Company
encounters in its selling activities. Due to the foregoing factors, quarterly
revenues and operating results are not predictable with any significant degree
of accuracy. In the event of any downturn in potential customers' businesses,
the domestic economy in general, or in international economies where the Company
derives substantial revenues, planned purchases of the Company's products may be
deferred or canceled, which could have a material adverse effect on the
Company's business, operating results, and financial condition. Because the
Company's operating expenses are based on anticipated revenue levels and because
a high percentage of the Company's expenses are relatively fixed, delays in the
recognition of revenues from even a limited number of license transactions could
cause significant variations in operating results from quarter to quarter and
could cause net income to fall significantly short of anticipated levels. In the
quarters ended September 28, 1997 and June 29, 1997, costs associated with the
Company's internal restructuring, aggregating $109.4 million, had a material
adverse effect on results of operations. The total restructuring charges
decreased by $1.2 million during the fourth quarter of fiscal 1997 primarily due
to adjusting the original estimate of the loss to be incurred on the sale of
land to the actual loss. Management continues to evaluate the Company's cost
structure in light of projected revenues and cash-flows, both of which are
variable and uncertain. There can be no assurance that the Company will not be
required to undertake additional restructuring activities in the future, which
would have a material adverse effect on the Company's business, results of
operations and financial condition.
 
       The Company's business has experienced and is expected to continue to
experience seasonality. International revenues comprise a significant percentage
of the Company's total revenues, and the Company may experience additional
variability in demand associated with seasonal buying patterns in
 
                                       40
<PAGE>
foreign markets. In particular, the Company's third quarter tends to reflect the
effects of summer slowing of international business activity, particularly in
Europe. In addition, variability and seasonality in the Company's business may
result from customer capital spending cycles, which tend to peak in the
Company's fourth quarter, and the Company's sales incentive plans for sales
personnel, which are measured on a calendar year basis. See "--Competition;
Pricing Risks," "--International Operations; Currency Fluctuations" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
LITIGATION
 
       Beginning on or about April 16, 1997, a total of 24 complaints alleging
violations of the federal securities laws were filed against the Company, Ernst
& Young LLP, the Company's independent auditors and certain Named Individual
Defendants (listed below) in the United States District Court for the Northern
District of California. Of the 24 complaints, 22 have been filed as purported
class actions by individuals who allege that they are individual investors who
purchased the Company's Common Stock during the purported class period; the
alleged class periods in the different complaints vary according to the date on
which the complaints were filed. The complaints name some or all of the
following current and former officers and directors of the Company as
defendants: Phillip E. White, Howard H. Graham, David H. Stanley, Ronald M.
Alvarez, Karen Blasing, D. Kenneth Coulter, Ira H. Dorf, Stephen E. Hill, Myron
(Mike) Saranga, Steven R. Sommer, Michael R. Stonebraker and Edwin C. Winder
(the "Named Individual Defendants"). On August 20, 1997, the District Court
entered an order consolidating all of the separately-filed class actions pending
at that time, designating the action as IN RE INFORMIX CORPORATION SECURITIES
LITIGATION, and designating as "related cases" all cases brought under the
federal securities laws then pending and any that may be filed after that date.
A consolidated amended class action complaint is set to be filed on April 3,
1998, and defendants will file a response to that consolidated, amended
complaint shortly thereafter. As required by the provisions of the Exchange Act,
as amended by the Private Securities Litigation Reform Act of 1995, the Court
has designated the lead plaintiffs in the federal action and has appointed lead
plaintiffs' counsel. For further description of these matters see "Legal
Proceedings--Actions Arising Under Federal and State Securities Laws."
 
       The Company also has been named as a nominal defendant in eight
derivative actions, purportedly brought on its behalf, filed in the Superior
Court of the State of California, County of San Mateo. The Court has appointed
lead plaintiff's counsel in all of these derivative actions, and the cases have
been consolidated under the caption IN RE INFORMIX CORPORATION DERIVATIVE
LITIGATION. The consolidated, amended complaint alleges that, based upon the
facts alleged in the federal and state securities class actions, defendants
breached their fiduciary duties to the Company, engaged in abuses of their
control of the Company, were unjustly enriched by their sales of the Company's
Common Stock, engaged in insider trading in violation of California law and
published false financial information in violation of California law. The
consolidated, amended complaint names as defendants Ernst & Young, the Named
Individual Defendants and Albert F. Knorp, Jr., James L. Koch, Thomas A.
McDonnell and Cyril J. Yansouni, the Company's non-management directors. The
plaintiff seeks unspecified damages on the Company's behalf from each of the
defendants. For further description of these matters see "Legal
Proceedings--Derivative Actions."
 
       Pursuant to Delaware law, the Company's Certificate of Incorporation, its
Bylaws and the indemnification agreements between the Company and each of its
current and former officers and directors, the Company is obligated to indemnify
its current and former officers and directors for certain liabilities arising
from their employment with or service to the Company. These indemnification
obligations require the Company to indemnify its current and former officers and
directors for any suit or other proceeding, threatened or actual, whether civil,
criminal, administrative, investigative, appellate or any other type of
proceeding, that arises as a result of any act or omission in the indemnitee's
capacity as an officer or director of the Company to the fullest extent
permitted under Delaware or any other applicable law. The indemnification
extends to any and all expenses (including but not limited to attorneys' fees
and
 
                                       41
<PAGE>
costs, and any other out-of-pocket expense) and/or liabilities of any type
(including but not limited to judgments, fines, excise taxes or penalties under
ERISA, and amounts paid in settlement) reasonably incurred in connection with
the investigation, defense, settlement or appeal of such proceedings. The
obligation to provide indemnification does not apply if the indemnitee is
adjudicated to be liable for fraudulent or criminal conduct.
 
       The Company has purchased directors' and officers' liability insurance to
reimburse it for the costs incurred in connection with its indemnification
obligations described above. For the period from August 1996 to August 1997, the
period in which most of the claims against the Company and certain of its
directors and officers were asserted, the Company had in place three directors
and officers liability insurance policies (the "1996 and 1997 D&O Policies"),
each providing $5 million in coverage for an aggregate of $15 million. The
primary policy and first excess policy were issued by Lloyds of London. The
second excess policy was issued by Admiral Insurance Company. The insurance
carriers have taken the position that litigation filed after the policy periods
of the 1996 and 1997 D&O Policies but arising from the same facts and
circumstances as claims filed during the period from August 1996 to August 1997,
"relates back" to the 1996 and 1997 D&O Policies. Thus, the issuance carriers
assert that actions filed after August 1997 do not implicate coverage under the
Company's D&O insurance policies for the period August 1997 to August 1998 (the
"Current D&O Policies"). The Current D&O Policies provide aggregate coverage of
$20 million, subject to various exclusions, including claims relating to the
restatement of the Company's financial reports. The 1996 and 1997 D&O Policies
provide that 100 percent of the costs incurred in defending claims asserted
jointly against the Company and its current and former officers and directors
are allocable to the individuals' defense and, thus, are covered by the policy.
However, the 1996 and 1997 D&O Policies do not provide any separate coverage for
the Company. Moreover, the Company does not have separate insurance to cover the
costs of its own defense or to cover any liability for any claims asserted
against it. The Company has not currently set aside any financial reserves
relating to any of the above-referenced actions.
 
       In addition, in July 1997, the Securities and Exchange Commission issued
a formal order of investigation of the Company and certain unidentified
individuals associated with the Company with respect to non-specified accounting
matters, public disclosures and trading activity in the Company's securities.
The Company is cooperating with the investigation and is providing all
information subpoenaed by the Commission.
 
       The pending federal and state securities actions are in the early stages
of discovery. Consequently, at this time it is not reasonably possible to
estimate the damages, or the range of damages, that the Company might incur in
connection with such actions. However, the uncertainty associated with
substantial unresolved litigation can be expected to have an adverse impact on
the Company's business. In particular, such litigation could impair the
Company's relationships with existing customers and its ability to obtain new
customers. Defending such litigation will likely result in a diversion of
management's time and attention away from business operations, which could have
a material adverse effect on the Company's results of operations. Such
litigation may also have the effect of discouraging potential acquirors from
bidding for the Company or reducing the consideration such acquirors would
otherwise be willing to pay in connection with an acquisition.
 
DEPENDENCE ON KEY PERSONNEL; PERSONNEL CHANGES; ABILITY TO RECRUIT PERSONNEL
 
       The Company's future performance will depend to a significant extent on
its ability to attract and retain highly skilled technical, sales, consulting,
marketing and management personnel. In particular, the Company is dependent upon
a number of key management and technical personnel, including Robert J.
Finocchio, Jr., the Company's Chairman, President and Chief Executive Officer,
Jean-Yves F. Dexmier, the Company's Executive Vice President and Chief Financial
Officer, and Myron (Mike) Saranga, the Company's Senior Vice President, Product
Management and Development. Mr. Finocchio and Mr. Dexmier have only recently
joined the Company, and of the officers and key employees, only Mr. Finocchio is
bound by an employment agreement, the terms of which are nonetheless at-will.
The loss
 
                                       42
<PAGE>
of the services of one or more of the Company's executive officers or key
employees could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
       Since the beginning of 1997, a number of senior management personnel and
other key employees have departed the Company, and to date, the Company has been
able to replace only some of the positions that have been vacated. Since the
first quarter of 1997, the Company has experienced a significant number of
voluntary resignations and has taken selective actions to reduce the number of
employees in certain functional areas. The Company had approximately 3,489
regular employees at December 31, 1997, compared to approximately 4,491 at
December 31, 1996. Voluntary attrition has remained high across all functional
areas. In fiscal 1997, the Company experienced high attrition rates in its
product development and sales groups and has had trouble attracting qualified
replacement personnel. The competition for employees in the software industry is
intense, and the Company expects that such competition will continue for the
foreseeable future. The Company has experienced difficulty in locating
candidates with appropriate qualifications and believes that recent financial
and business developments at the Company have made recruitment more difficult.
In November 1997, the Company implemented an option repricing program in an
effort to retain existing employees and, following further declines in the price
of its Common Stock, announced a second repricing in December 1997, which was
effective in January 1998. There can be no assurance that such programs will be
effective in retaining existing employees. There can be no assurance that the
Company will be successful in attracting, training and retaining qualified
personnel, and the failure to do so, particularly in key functional areas such
as product development and sales, could have a material adverse effect on the
Company's business, results of operations and financial condition. In addition,
new employees hired by the Company generally require substantial training in the
use and implementation of the Company's products and in the Company's
procedures. As a result, substantial employee turnover could have an adverse
effect on results of operations in future quarters.
 
RISKS ASSOCIATED WITH PREFERRED STOCK FINANCINGS
 
       In August 1997, the Company raised net proceeds of $37.6 million through
the issuance of newly designated Series A Preferred. In November 1997, the
Company raised an additional $50.0 million in net proceeds (excluding of a $1.0
million fee paid to a financial advisor of the Company) through the issuance of
the Series B Preferred. Simultaneously with the closing of the Series B
Preferred, the holders of the Series A Preferred exchanged all their outstanding
shares of Series A Preferred for newly designated Series A-1 Preferred, having
substantially similar rights, preferences and privileges as the Series A
Preferred with the exception of certain amendments, including revisions to the
terms under which such shares become mandatorily redeemable.
 
       While the issuance of the Preferred Stock in these transactions provided
the Company with additional working capital required to fund the Company's
continuing operations, the Company's agreements with the purchasers of the
Series A-1 Preferred and the Series B Preferred contain covenants that could
impair the Company's ability to engage in various corporate transactions in the
future, including financing transactions and certain transactions involving a
change-in-control or acquisition of the Company, or that could otherwise
disadvantage the Company and the holders of its Common Stock. In particular,
acquisitions of the Company may not be affected without the consent of the
holders of the outstanding Preferred Stock or without requiring the acquiring
entity to assume the Preferred Stock or cause such Preferred Stock to be
redeemed. These provisions are likely to make an acquisition of the Company more
difficult and expensive and could discourage potential acquirors. Certain
covenants of the Company, made in connection with the issuance of the Preferred
Stock, may also have the effect of limiting the Company's ability to obtain
additional financing by, for example, providing the holders of Preferred Stock
certain rights of first offer and prohibiting the Company from issuing
additional Preferred Stock without the consent of such holders.
 
       The terms of the financing agreements pursuant to which the Preferred
Stock was issued also include certain penalty provisions that are triggered in
the event the Company fails to satisfy certain obligations. In particular, the
holders of the Series A-1 Preferred will become entitled to an annual
 
                                       43
<PAGE>
dividend of $6.0 million, payable quarterly in cash, in the event the Company
fails to satisfy certain covenants, including the failure to have a registration
statement covering the Common Stock issuable upon conversion of the Series A-1
Preferred declared effective by the Commission within 180 days of a registration
request from the holders of Series A-1 Preferred; the failure to obtain
stockholder approval of the issuance of the Common Stock issuable upon
conversion of the Series A-1 Preferred in the event that such approval becomes
required by the rules of the Nasdaq National Market; and the failure to redeem
any shares of Series A-1 Preferred held by a holder of Series A-1 Preferred who
objects to a change-in-control transaction, if the transaction does not satisfy
certain financial thresholds relating to the market capitalization and trading
volume of any acquiring entity. In the event the Company becomes obligated to
pay such dividends, the holders of the Series A-1 Preferred will become
immediately entitled to designate a number of members of the Company's Board of
Directors corresponding, as a percentage of the total number of members, to the
percentage of the Company's outstanding Common Stock held by such holders
(assuming the conversion into Common Stock of the outstanding Series A-1
Preferred). The holders of the Series B Preferred are entitled to receive a
cumulative dividend at an annual rate of 5% of the face value of each share of
Series B Preferred, resulting in an aggregate annual dividend of $2.5 million.
The dividend is generally payable upon the conversion of the Series B Preferred
or redemption of the Series B Preferred and may be paid in cash or, at the
Company's election and subject to certain conditions, in shares of Common Stock.
In the event the holders of Preferred Stock become entitled to receive cash
dividends or to have their Preferred Stock redeemed, there can be no assurances
that the Company will be able to fund such a payment or redemption, and even if
funding is available, substantial dividend payments could have a material
adverse effect on the Company's business and financial condition. See "--Need
for Additional Financing; Customer Financing" and "--Antitakeover Protection."
 
       Both the Series A-1 Preferred and the Series B Preferred are convertible
into shares of the Company's Common Stock based on the trading prices of the
Common Stock during future periods that are described in the respective
financing agreements. The number of shares of Common Stock that may ultimately
be issued upon conversion is therefore presently indeterminate. If, in
accordance with the terms of the financing agreements, the conversion price of
the Preferred Stock is determined during a period when the trading price of the
Common Stock is low, the resulting number of shares of Common Stock issuable
upon conversion of the Preferred Stock could result in substantial dilution to
the holders of Common Stock. In addition, the Company issued the Series A-1
Warrant to the holders of the Series A-1 Preferred to acquire up to an
additional 140,000 shares of Series A-1 Preferred for an aggregate purchase
price of $35 million. The Series A-1 Warrant was exercised in part in February
1998 for 60,000 shares of Series A-1 Preferred, resulting in $14.1 million in
net proceeds to the Company. In February 1998, all 220,000 shares of Series A-1
Preferred which were then outstanding were converted into 12,769,208 shares of
Common Stock. The Company is also obligated to issue the Series B Warrants upon
conversion of the Series B Preferred. The Series A-1 Warrant and the Series B
Warrants, to the extent exercised, will have a further dilutive effect.
 
COMPETITION; PRICING RISKS
 
       The Company faces intense competition in the market for RDBMS software
products. The market for the Company's products is subject to rapid
technological change and frequent new product introductions and enhancements,
and the Company's competitors in the market include several large vendors that
develop and market databases, applications, development tools or decision
support products. The Company's principal competitors include Computers
Associates, IBM, Microsoft, NCR/Teradata, Oracle and Sybase. Several of the
Company's competitors have significantly greater financial, technical, marketing
and other resources than the Company. As a result, they may be able to respond
more quickly to new or emerging technologies and changes in customer
requirements or to devote greater resources to the development, promotion and
sale of their products than the Company. Any failure by the Company to compete
successfully with its existing competitors or future competitors could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
                                       44
<PAGE>
       Several of the Company's competitors have announced the development of
enhanced versions of their principal database products that are intended to
improve the performance or expand the capabilities of their existing products.
New or enhanced products by existing competitors or new competitors could result
in greater price pressure on the Company's products. In addition, the industry
movement to new operating systems, like Windows NT, access through low-end
desktop computers, and access to data through the Internet may cause downward
pressure on prices of database software and related products. The bundling of
software products for promotional purposes or as a long-term pricing strategy by
certain of the Company's competitors could also result in reductions in the
price the Company may charge for its products. In addition, the Company's own
practices of bundling its software products for enterprise licenses or for
promotional purposes with the Company's partners could also result in reduction
in the price the Company may charge for its products. In particular, the pricing
strategies of competitors in the industry have historically been characterized
by aggressive price discounting to encourage volume purchasing by customers. If
such downward pressure on prices were to occur, the Company's operating margins
would be adversely affected. Existing and future competition or changes in the
Company's product or service pricing structure or product or service offerings
could result in an immediate reduction in the prices of the Company's products
or services. If significant price reductions in the Company's products or
services were to occur and not be offset by increases in sales volume, the
Company's business, results of operations and financial condition would be
adversely affected. There can be no assurance that the Company will continue to
compete successfully with its existing competitors or will be able to compete
successfully with new competitors.
 
UNCERTAIN GROWTH RATES; TECHNOLOGICAL CHANGE AND NEW PRODUCTS
 
       Over the last several years, the RDBMS industry has expanded at
significant growth rates, due in part to the continuing development of new
technologies and products responsive to customer requirements. Recently,
however, both industry analysts and competitors have predicted that such high
growth rates will not be maintained in future periods. Recent instability in the
Asian-Pacific economies and financial markets, which had previously been cited
as a potentially strong source of revenue growth for relational database
software companies, has introduced additional uncertainty concerning industry
growth rates. In the event industry growth rates should decline for any reason,
the markets for the Company's products would likely be adversely affected, which
would have a negative impact on the Company's business, results of operations,
financial condition and cash flows. See "--Fluctuations in Quarterly Results;
Seasonality" and "--International Operations; Currency Fluctuations."
 
       In addition, the market for the Company's products and services is
characterized by rapidly changing technology, changing customer needs, frequent
new product introductions and evolving industry standards that may render
existing products and services obsolete. The life cycles of the Company's
products are difficult to estimate. The Company's growth and future financial
performance will depend upon its ability to enhance its existing products and to
introduce new products on a timely and cost-effective basis that meet dynamic
customer requirements. There can be no assurance that the Company will be
successful in developing new products or enhancing its existing products or that
such new or enhanced products will receive market acceptance or be delivered
timely to the market. The Company's product development efforts are expected to
continue to require substantial investments by the Company, and there can be no
assurance that the Company will have sufficient resources to make the necessary
investments. The Company has experienced product development delays in the past
and may experience delays in the future. Delays in the scheduled availability or
a lack of market acceptance of its products or failure to accurately anticipate
customer demand and meet customer performance requirements could have a material
adverse effect on the Company's business, results of operations and financial
condition. In addition, products as complex as those offered by the Company may
contain undetected errors or bugs when first introduced or as new versions are
released. There can be no assurance that, despite testing, new products or new
versions of existing products will not contain undetected errors or bugs that
will delay the introduction or commercial acceptance of such products. A key
determinative factor in the Company's success will continue to be the ability of
the Company's products to operate and perform well with existing
 
                                       45
<PAGE>
and future leading, industry-standard application software products intended to
be used in connection with RDBMS. Failure to meet in a timely manner existing or
future interoperability requirements of certain independent vendors could
adversely affect the market for the Company's products. Commercial acceptance of
the Company's products and services could also be adversely affected by critical
or negative statements or reports by brokerage firms, industry and financial
analysts and industry periodicals concerning the Company, its products, business
or competitors or by the advertising or marketing efforts of competitors, or
other factors that could affect consumer perception. See "Uncertain Impact of
Restatement of Financial Statements," "--Need for Additional Financing; Customer
Financing," "--Working Capital Deficit" and "--Dependence on Key Personnel;
Personnel Changes; Ability to Recruit Personnel."
 
       In recent years, the types and quantities of data required to be stored
and managed has grown increasingly complex and includes, in addition to
conventional character data, audio, video, text, and three-dimensional graphics
in a high-performance scalable environment. During fiscal 1996, the Company
invested substantial resources in developing its ORDBMS product line. The market
for products offering object-relational database functionality is new and
evolving, and its growth depends upon a growing need to store and manage complex
data and on broader market acceptance of the Company's products as a solution
for this need. As a result, there can be no assurance that organizations will
choose to make the transition from conventional RDBMS to ORDBMS. Delays in
market acceptance of object-relational database management products offered by
the Company could have an adverse effect on the Company's results of operations
and financial condition. See "Business--Products" and "--Product Development."
 
INTERNATIONAL OPERATIONS; CURRENCY FLUCTUATIONS
 
       International sales represented approximately 54% of total revenues for
both fiscal 1997 and 1996. The Company's international operations and financial
results could be significantly affected by factors associated with international
operations such as changes in foreign currency exchange rates and uncertainties
relative to regional, political and economic circumstances, as well as by other
factors associated with international activities. In particular, recent
instability in the Asian-Pacific economies and financial markets, which
accounted for approximately 12% and 13% of the Company's total revenues in
fiscal 1997 and 1996, respectively, could have an adverse effect on the
Company's operating results in future quarters. Most of the Company's
international revenue and expenses are denominated in local currencies. Due to
the substantial volatility of currency exchange rates, among other factors, the
Company cannot predict the effect of exchange rate fluctuations on future
operating results. Although the Company takes into account changes in exchange
rates over time in its pricing strategy, it does so only on an annual basis,
resulting in substantial pricing exposure as a result of foreign exchange
volatility during the period between annual pricing reviews. In addition, the
sales cycles for the Company's products is relatively long, depending on a
number of factors including the level of competition and the size of the
transaction. Foreign currency fluctuations could, therefore, result in
substantial changes in the financial impact of a specific transaction between
the time of initial customer contact and revenue recognition. As a result of the
foregoing factors, the Company's business, results of operations and financial
condition could be materially and adversely affected by fluctuations in foreign
currency exchange rates. See "--Fluctuations in Quarterly Results; Seasonality."
 
       The Company has implemented a foreign exchange hedging program consisting
principally of the purchase of forward foreign exchange contracts, which is
intended to hedge the value of accounts receivable or accounts payable
denominated in foreign currencies against fluctuations in exchange rates until
such receivables are collected or payables are disbursed. This program involves
the use of forward contracts in the primary European and Asian currencies. The
Company has limited unhedged transaction exposures in certain secondary
currencies in Latin America, Eastern Europe and Asia because there are limited
forward currency exchange markets in these currencies. The Company does not
attempt to hedge the translation to United States dollars of foreign denominated
revenues and expenses not yet earned or incurred. Notwithstanding the Company's
efforts to manage foreign exchange risk, there can be no assurances that the
Company's hedging activities will adequately protect the Company against the
risks
 
                                       46

associated with foreign currency fluctuations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Other Income, Net."
 
YEAR 2000 RISKS
 
       Many currently installed computer systems and software products 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.
 
       The Company has recently commenced a program, to be substantially
completed by the Fall of 1999, to review the Year 2000 compliance status of the
software and systems used in its internal business processes, to obtain
appropriate assurances of compliance from the manufacturers of these products
and agreement to modify or replace all non-compliant products. In addition, the
Company is considering converting certain of its software and systems to
commercial products that are known to be Year 2000 compliant. Implementation of
software products of third parties, however, will require the dedication of
substantial administrative and management information resources, the assistance
of consulting personnel from third party software vendors and the training of
the Company's personnel using such systems. Based on the information available
to date, the Company believes it will be able to complete its Year 2000
compliance review and make necessary modifications prior to the end of 1999.
Software or systems which are deemed critical to the Company's business are
scheduled to be Year 2000 compliant by the end of 1998. Nevertheless,
particularly to the extent the Company is relying on the products of other
vendors to resolve Year 2000 issues, there can be no assurances that the Company
will not experience delays in implementing such products. If key systems, or a
significant number of systems were to fail as a result of Year 2000 problems or
the Company were to experience delays implementing Year 2000 compliant software
products, the Company could incur substantial costs and disruption of its
business, which would potentially have a material adverse effect on the
Company's business and results of operations.
 
       The Company in its ordinary course of business tests and evaluates its
own software products. The Company believes that its software products are
generally Year 2000 compliant, meaning that the use or occurrence of dates on or
after January 1, 2000 will not materially affect the performance of the
Company's software products with respect to four digit date dependent data or
the ability of such products to correctly create, store, process and output
information related to such date data. However, there can be no assurance that
the Company will not subsequently learn that certain of its software products do
not contain all necessary software routines and codes necessary for the accurate
calculation, display, storage and manipulation of data involving dates. In
addition, in certain circumstances, the Company has warranted that the use or
occurrence of dates on or after January 1, 2000 will not adversely affect the
performance of the Company's products with respect to four digit date dependent
data or the ability to create, store, process and output information related to
such data. If any of the Company's licensees experience Year 2000 problems, such
licensees could assert claims for damages against the Company. The Company's
license agreements in most cases limit liability to prevent unlimited exposure
from such claims.
 
       The Company has identified a separate budget of approximately $1.7
million for investigating and remedying issues related to Year 2000 compliance
involving software or systems used in its internal operations. However, the
Company has only recently initiated its Year 2000 compliance program and there
can be no assurances that the program will be completed on a timely basis and
within the current projected budget. To the extent the costs of implementing the
program greatly exceed the budget, such costs will have a material adverse
effect on the Company's business, financial condition and results of operations.
 
       In addition, the purchasing patterns of customers and potential customers
may be affected by Year 2000 issues. Many companies are expending significant
resources to correct their current software systems for Year 2000 compliance.
These expenditures may result in reduced funds available to purchase software
 
                                       47
<PAGE>
products such as those offered by the Company, which could have an adverse
effect on the Company's business, results of operations and financial condition.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISKS OF INFRINGEMENT
 
       The Company's success depends on proprietary technology. To protect its
proprietary rights, the Company relies primarily on a combination of patent,
copyright and trademark laws, trade secrets, confidentiality procedures,
contractual provisions contained in its license agreements and technical
measures. The Company seeks to protect its software, documentation and other
written materials under trade secret and copyright laws, which provide only
limited protection. The Company holds one United States patent and several
pending applications. There can be no assurance that any other patents covering
the Company's inventions will issue or that any patent, if issued, will provide
sufficiently broad protection or will prove enforceable in actions against
alleged infringers.
 
       The Company's products are generally licensed to end-users on a
"right-to-use" basis pursuant to a license that restricts the use of the
products for the customer's internal business purposes. The Company also relies
on "shrink wrap" licenses, which include a notice informing the end-user that,
by opening the product packaging, the end-user agrees to be bound by the
Company's license agreement printed on the package. Despite such precautions, it
may be possible for unauthorized third parties to copy aspects of its current or
future products or to obtain and use information that the Company regards as
proprietary. In particular, the Company has licensed the source code of its
products to certain customers under certain circumstances and for restricted
uses. The Company has also entered source code escrow agreements with a number
of its customers that generally require release of source code to the customer
in the event of the Company's bankruptcy, liquidation or otherwise ceasing to
conduct business. There can be no assurance that the Company's means of
protecting its proprietary rights will be adequate or that the Company's
competitors will not independently develop similar or superior technology.
Policing unauthorized use of the Company's software is difficult, and while the
Company is unable to determine the extent to which piracy of its software
products exists, software piracy can be expected to be a persistent problem. In
addition, the laws of some foreign countries do not protect the Company's
proprietary rights to the same extent as do the laws of the United States, and
"shrink-wrap" licenses may be wholly or partially unenforceable under the laws
of certain jurisdictions. Litigation may be necessary in the future to enforce
the Company's intellectual property rights, to protect the Company's trade
secrets or to determine the validity and scope of the proprietary rights of
others. Such litigation could result in substantial costs and diversion of
resources and management attention and could have a material adverse effect on
the Company's business, results of operations and financial condition.
 
       The Company is not aware that any of its software product offerings
infringes the proprietary rights of third parties. There can be no assurance,
however, that third parties will not claim infringement by the Company with
respect to its current or future products. The Company expects that software
product developers will increasingly be subject to infringement claims as the
number of products and competitors in the Company's industry segment grows and
the functionality of products in different industry segments overlaps. 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 licensing agreements, if
required, may not be available on terms acceptable to the Company or at all,
which could have a material adverse effect on the Company's business, results of
operations and financial condition. See "Business--Intellectual Property."
 
PRODUCT LIABILITY
 
       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, however, that the limitation of liability
provisions contained in the Company's license agreements may not be effective
under the laws of certain jurisdictions. Although the Company has not
experienced any product liability claims to date, the sale and support of
products by the Company may entail the risk of such claims, and there can be
 
                                       48
<PAGE>
no assurance that the Company will not be subject to such claims in the future.
A product liability claim brought against the Company could have a material
adverse effect on the Company's business, operating results and financial
condition.
 
ANTITAKEOVER PROTECTIONS
 
       The Company is authorized to issue 5,000,000 shares of undesignated
Preferred Stock, of which 440,000 shares have been designated Series A
Preferred, none of which is outstanding; of which 440,000 shares have been
designated Series A-1 Preferred, of which 220,000 shares were previously
outstanding (including 60,000 shares of Series A-1 Preferred which were issued
upon partial exercise of the Series A-1 Warrant) and converted into 12,769,908
shares of Common Stock in February 1998 and of which 80,000 shares remain
issuable upon exercise of the Series A-1 Warrant; and of which 50,000 shares
have been designated Series B Preferred, of which 50,000 shares are outstanding.
Subject to the prior consent of the holders of the Series A-1 Preferred and the
Series B Preferred, the Board of Directors has the authority to issue additional
shares of Preferred Stock in one or more series and to fix the price, rights,
preferences, privileges and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
a series or the designation of such series, without any further vote or action
by the Company's stockholders. To date, the Company has used its ability to
designate and issue new series of Preferred Stock in transactions intended to
raise additional capital for the Company. The ability to issue additional shares
of Preferred Stock, however, also provides desirable flexibility in connection
with possible acquisitions and other corporate purposes but could also have the
effect of delaying, deferring or preventing a change in control of the Company
without further action by the stockholders and may adversely affect the market
price of the Common Stock and the voting and other rights of the holders of
Common Stock. The issuance of Preferred Stock with voting and conversion rights
may adversely affect the voting power of the holders of Common Stock, including
the loss of voting control to others. In particular, certain rights, preferences
and privileges of the Series A-1 Preferred and Series B Preferred could have the
effect of preventing or discouraging potential bids to acquire the Company
unless the terms of such acquisition are approved by such stockholders. See
"--Risks Associated with Convertible Preferred Stock Financings."
 
       Certain provisions of the Company's Amended and Restated Certificate of
Incorporation and Bylaws eliminate the right of stockholders to act by written
consent without a meeting and specify certain procedures for nominating
directors and submitting proposals for consideration at stockholder meetings.
The Board of Directors of the Company is divided into three classes, with each
class standing for election once every three years. Such provisions are intended
to enhance the likelihood of continuity and stability in the composition of the
Board of Directors and in the policies formulated by the Board of Directors and
to discourage certain types of transactions which may involve an actual or
threatened change of control of the Company. Such provisions are designed to
reduce the vulnerability of the Company to an unsolicited acquisition proposal
and, accordingly, could discourage potential acquisition proposals and could
delay or prevent a change in control of the Company. Such provisions are also
intended to discourage certain tactics that may be used in proxy fights but
could, however, have the effect of discouraging others from making tender offers
for the Company's shares and, consequently, may also inhibit fluctuations in the
market price of the Company's Common Stock that could result from actual or
rumored takeover attempts. These provisions may also have the effect of
preventing changes in the management of the Company. In addition, the Company
has adopted a Rights Agreement (the "Rights Agreement"), commonly referred to as
a "poison pill," which could also discourage potential acquirors.
 
       The Company is subject to Section 203 of the Delaware General Corporation
Law (the "Antitakeover Law"), which regulates corporate acquisitions. The
Antitakeover Law prevents certain Delaware corporations, including those whose
securities are listed for trading on the Nasdaq National Market, from engaging,
under certain circumstances, in a "business combination" with any "interested
stockholder" for three years following the date that such stockholder became an
interested stockholder. For purposes of the Antitakeover Law, a "business
combination" includes, among other things, a merger or consolidation
 
                                       49
<PAGE>
involving the Company and the interested stockholder and the sale of more than
10% of the Company's assets. In general, the Antitakeover Law defines an
"interested stockholder" as any entity or person beneficially owning 15% or more
of the outstanding voting stock of the Company and any entity or person
affiliated with or controlling or controlled by such entity or person. A
Delaware corporation may "opt out" of the Antitakeover Law with an express
provision in its original certificate of incorporation or an express provision
in its certificate of incorporation or bylaws resulting from amendments approved
by the holders of at least a majority of the company's outstanding voting
shares. The Company has not "opted out" of the provisions of the Antitakeover
Law.
 
STOCK PRICE VOLATILITY
 
       The market price of the Company's Common Stock has in the past been
highly volatile and is expected to continue to be subject to significant price
and volume fluctuations in the future based on a number of factors, including
market uncertainty about the Company's financial condition or business prospects
or the prospects for the RDBMS market in general; shortfalls in the revenues or
results of operations of the Company or its principal competitors from revenues
or results of operations expected by securities analysts; announcements of new
products by the Company or its competitors; quarterly fluctuations in the
Company's financial results or the results of other software companies,
including those of direct competitors of the Company; changes in analysts'
estimates of the Company's financial performance, the financial performance of
competitors, or the financial performance of software companies in general; the
introduction of new products or product enhancements by the Company or its
competitors; general conditions in the software industry; changes in prices for
the Company's products or competitors' products; changes in revenue growth rates
for the Company, its competitors or the RDBMS market in general; changes in the
mix of revenues attributable to domestic and international sales; and seasonal
trends in technology purchases and other general economic conditions. In
addition, the stock market may from time to time experience extreme price and
volume fluctuations, which particularly affect the market for the securities of
many technology companies and which have often been unrelated to the operating
performance of the specific companies. There can be no assurance that the market
price of the Company's Common Stock will not experience significant fluctuations
in the future. See "--Uncertain Impact of Restatement of Financial Statements,"
"--Need for Additional Financing; Customer Financing" and "--Fluctuations in
Quarterly Results; Seasonality."

------------------------------
 
(1) Potential realizable value is based on the assumption that the Common Stock
    of the Company appreciates at the annual rate shown (compounded annually)
    from the date of grant until the expiration of the ten year option term.
    These numbers are calculated based on the requirements promulgated by the
    Commission and do not reflect the Company's estimate of future stock price
    growth.
 
(2) Based on options to acquire 13,107,338 shares granted under the 1994 Plan,
    the Director Plan and the Company's 1987 Non-Statutory Stock Option Plan.
    Such option grants include shares granted as a result of the Company's
    November 1997 option repricing program. See "--Stock Option Repricing."
    Unless otherwise specified herein, all options granted to the Named
    Executive Officers were under the 1994 Plan.
 
(3) Options were granted at an exercise price equal to not less than the fair
    market value of the Company's Common Stock on the date of grant as reported
    on the Nasdaq National Stock Market. The exercise price may be paid in cash,
    check, by delivery of already-owned shares of the Company's Common Stock
    subject to certain conditions or pursuant to a cashless exercise procedure
    under which the optionee provides irrevocable instructions to a brokerage
    firm to sell the purchased shares and to remit to the Company, out of the
    sale proceeds, an amount equal to the exercise price plus all applicable
    withholding taxes.
 
(4) Twenty-five percent (25%) of the shares issuable upon exercise of options
    granted under the 1994 Plan become vested on the first anniversary of the
    date of grant, and the remaining shares vest over three years at the rate of
    25% of the shares subject to option vesting on each successive anniversary
    of the option grant date. Unless otherwise specified, options granted to
    Named Executive Officers in fiscal 1997, including options granted outside
    the 1994 Plan, are subject to the Company's standard four year vesting
    schedule described above.
 
(5) The options to purchase 1,500,000 option shares of Common Stock granted to
    Mr. Finocchio were issued in connection with his Employment Agreement with
    the Company. See "Employment Agreements and Change in Control Arrangements."
    Of the 1,500,000 option shares granted to Mr. Finocchio, 1,000,000 were
    granted under the 1994 Plan and 500,000 were granted under the Company's
    1997 Non-Statutory Stock Option Plan. In addition, in January 1998, the
    Company granted Mr. Finocchio an additional option under the 1994 Plan to
    acquire 500,000 shares of Common Stock, subject to vesting in equal annual
    installments over four years.

    with such repricing, Mr. Saranga forfeited the right to purchase 46,000
    shares of Common Stock under options previously granted to him. See "--Stock
    Option Repricing." Mr. Saranga's option to purchase up to 100,000 shares of
    the Common Stock of the Company granted in September 1997 under the 1994
    Plan will become vested on December 31, 2000 if Mr. Saranga remains an
    employee of the Company on such date. In January 1998, the Company granted
    Mr. Saranga the right to receive 35,000 performance shares of Common Stock
    under the 1994 Plan each of the next three years if certain financial
    milestones are met as of January 1, 1999, 2000 and 2001. Such performance

    shall lapse if Mr. Saranga remains an employee of the Company on January 1,
    2001.

STOCK OPTION REPRICING
 
       In September 1997, the Company's Board of Directors authorized the
repricing of outstanding options to purchase Common Stock under the Company's
stock option plans. Employees, including executive officers, were eligible to
participate only if they remained actively employed at the effective date of the
repricing and were only permitted to exchange options outstanding prior to May
1, 1997. The repricing/option exchange was effective November 21, 1997 (the
"Repricing Effective Date"). The repricing program offered eligible employees
the opportunity to exchange eligible outstanding options with exercise prices in
excess of the closing sales price of the Company's Common Stock on the Repricing
Effective Date for a new option with an exercise price equal to such price.
Other than the exercise price, each new option issued upon exchange has terms
substantially equivalent to the surrendered option, including with respect to
the number of shares, vesting terms and expiration. Options issued in connection
with the exchange may not be exercised for a period of one year from the
Repricing Effective Date, however. In addition, officers of the Company
participating in the option exchange were required to forfeit 20% of the shares
subject to each option being surrendered. The exercise price for repriced
options was $7.1563, the closing sales price of the Company's Common Stock on
the Repricing Effective Date.
 
       The following table provides information with respect to the November
1997 repricing for the Named Executive Officers and for other executive officers
of the Company who elected to reprice options. These are the only executive
officers of the Company who had their options repriced.

new option with an exercise price equal to the closing sales price on the Second
Repricing Effective Date. Options exchanged in the second repricing may not be
exercised for a period of one year from the Second Repricing Effective Date.
 
EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS
 
       On July 18, 1997, the Company entered into an at-will employment
agreement with Mr. Finocchio, the Company's Chairman, President and Chief
Executive Officer. The agreement provides for an annual base salary of $460,000,
subject to annual review concerning increases. Pursuant to the agreement, the
Company granted Mr. Finocchio an option to purchase 1,000,000 shares of Common
Stock under the 1994 Plan at an exercise price per share of $10.8125, subject to
vesting in equal annual installments over four years and an option under the
Company's 1997 Non-Statutory Stock Option Plan to acquire an additional 500,000
shares of Common Stock, also at an exercise price of $10.8125 and subject to
vesting under the same terms as the grant under the 1994 Plan. In the event of a
merger or change in control of the Company, the exercisability of Mr.
Finocchio's options will accelerate so as to become fully vested. In January
1998, the Company granted Mr. Finocchio an additional option under the 1994 Plan
to acquire 500,000 shares of Common Stock, subject to vesting in equal annual
installments over four years.
 
       On September 24, 1997, the Company entered into an at-will employment
letter agreement with Jean-Yves F. Dexmier, the Company's Executive Vice
President and Chief Financial Officer, which provides for an annual base salary
of $350,000 and an annual cash bonus based on the achievement of individual and
Company performance objectives. In the event Mr. Dexmier is terminated without
cause within the first twelve months of his employment with the Company, he will
be entitled to receive severance in an amount equal to one year of base salary
plus any bonus he would have been entitled to receive under the Company's
executive compensation plan. If such termination occurs after Mr. Dexmier's
first twelve months with the Company, he shall be entitled to receive as
severance an amount equal to six months base salary. If there is a change of
control of the Company within the first twelve months Mr. Dexmier is employed
with the Company, Mr. Dexmier will be entitled to receive $1,000,000 less any
stock option profit realized upon the change in ownership. In connection with
his employment, the Company granted Mr. Dexmier an option under the 1994 Plan to
acquire 500,000 shares of Common Stock at an exercise price of $6.8125, subject
to vesting in equal annual installments over four years. In January 1998, the
Company granted Mr. Dexmier an additional option under the 1994 Plan to acquire
100,000 shares of Common Stock, subject to equal annual installments over four
years.
 
       On September 18, 1997, the Company entered into an at-will employment
letter agreement with Wesley Raffel, the Company's Vice President, North
American Field Operations, which provides for an annual base salary of $250,000
and an annual cash bonus based on the achievement of individual and Company
performance objectives. In the event of a change in the Chief Executive Officer
or a change in ownership of the Company, Mr. Raffel will be entitled to receive
severance in an amount equal to one year
 
                                       60
<PAGE>
of base salary. In connection with his employment, the Company granted Mr.
Raffel an option under the 1994 Plan to acquire 325,000 shares of Common Stock
at an exercise price of $7.3438, subject to vesting in equal annual installments
over four years.
 
       In October 1997, the Company entered into Change of Control Agreements
(the "Change of Control Agreements") with Messrs. Dexmier and Raffel, Myron
(Mike) Saranga, the Company's Senior Vice President, Product Management and
Development, and Karen Blasing, the Company's former Vice President and
Corporate Controller. The Change of Control Agreements, which are substantially
similar for each executive officer, provide that in the event a change in
control of the Company occurs, the exercisability of each executive officer's
options will accelerate so as to become fully vested.
 
       In January 1998, the Company entered into an at-will employment letter
with Susan T. Daniel, the Company's Vice President, Human Resources, which
provides for an annual base salary of $230,000 and an annual cash bonus based on
the achievement of individual and Company performance objectives. Ms. Daniel
will also receive $7,500 annually her first two years of employment if she
remains employed with the Company on the anniversary date of her employment with
the Company. In connection with her employment, the Company granted Ms. Daniel
an option under the 1994 Plan to acquire 200,000 shares of Common Stock at a per
share exercise price of $7.4688, subject to vesting in equal annual installments
over four years. In the event of a change of ownership of the Company within Ms.
Daniel's first two years of employment with the Company where Ms. Daniel's
employment is terminated within 90 days of the change of control event other
than for cause, she will be entitled to receive severance in an amount equal to
one (1) year base salary. If a change of control in the ownership of the Company
occurs within Ms. Daniel's first six months with the Company, the exercisability
of her options will accelerate as to two years additional vesting. If such
change of control takes place after such six month period, the exercisability of
Ms. Daniel's options will accelerate so as to become fully vested.
 
       In January 1998, the Company entered into an at-will employment letter
with Gary Lloyd, the Company's Vice President, Legal, General Counsel and
Secretary, which provides for an annual base salary of $200,000 and an annual
cash bonus based on the achievement of individual and Company performance
objectives. In connection with his employment, the Company granted Mr. Lloyd an
option under the 1994 Plan to acquire 150,000 shares of Common Stock at a per
share exercise price of $5.7500, subject to vesting in equal installments over
four years. If a change of control in the ownership of the Company occurs within
Mr. Lloyd's first six months with the Company, the exercisability of his options
will accelerate as to two years additional vesting. If such change of control
takes place after such six month period, the exercisability of Mr. Lloyd's
options will accelerate so as to become fully vested.
 
       On March 18, 1998, the Company entered into an at-will employment letter
agreement with Diane L. Fraiman, the Company's Vice President, Corporate
Marketing, which provides for an annual base salary of $250,000 and an annual
cash bonus based on the achievement of individual and Company performance
objectives. Pursuant to her employment letter, Ms. Fraiman received a $135,000
signing bonus, which Ms. Fraiman will be required to repay in full if she
terminates her employment with the Company prior to the first anniversary of her
commencement date. Ms. Fraiman will be required to repay half that amount if she
terminates her employment after the first anniversary date but prior to the
second anniversary date. In connection with her employment with the Company, the
Company granted Ms. Fraiman option to acquire 200,000 shares of Common Stock at
an exercise price equal to the closing sales price of the Company's Common Stock
as reported by The Nasdaq Stock Market on Ms. Fraiman's employment commencement
date with the Company, subject to vesting in equal annual installments over four
years. If there is a change in control of the Company within the first six
months after the date of Ms. Fraiman's employment letter, the vesting of Ms.
Fraiman's options will accelerate as to two year's additional vesting. If such
change of control occurs after such six month anniversary, Ms. Fraiman's options
will accelerate so as to become fully vested.

       Other than the employment arrangements described above, the Company does
not have employment agreements with any other current executive officer or
director.
 
       In connection with Philip E. White's resignation as Chairman, President
and Chief Executive Officer in July 1997, and pursuant to his employment
agreement with the Company, the Company was obligated to pay Mr. White six
months salary at a rate of $39,583.34 per month from the time of his
resignation.
 
       The Company has entered into severance arrangements with additional
former executive officers of the Company. See "Certain Relationships and Related
Transactions."
 
       The Company has also adopted a Rights Agreement, commonly referred to as
a poison pill. The Company's Board of Directors has declared a dividend of one
Purchase Right ("Right") under the Company's Rights Agreement for each share of
the Company's Common Stock outstanding on September 17, 1991 or thereafter
issued. When exercisable, each Right initially entitles the holder to purchase
one share of Common Stock at a specified price. The Rights become exercisable on
the earlier of: (i) the tenth day (or such later date as may be determined by a
majority of the Company's Directors not affiliated with the acquiring person or
group (the "Continuing Directors")) after a person or group has acquired, or
obtained the right to acquire, beneficial ownership of 20% of more of the
Company's outstanding Common Stock or (ii) the tenth business day (or such later
date as may be determined by a majority of the Continuing Directors) following
the consummation of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in beneficial ownership by
a person or group of 20% or more of the Company's outstanding Common Stock. If
an acquiror obtains 20% or more of the Company's outstanding Common Stock (other
than in certain permitted transactions), and unless the Rights are earlier
redeemed, the holder of each unexercised Right will have the right to receive
shares of the Company's Common Stock having a value equal to two times the
purchase price. Similarly, unless the Rights are earlier redeemed, after the
tenth day following certain acquisition transactions, proper provision must be
made so that holders of Rights (other than those beneficially owned by an
acquiring person, which will thereafter be void) will thereafter have the right
to receive, upon exercise, shares of common stock of the acquiring company
having a value equal to two times the purchase price. The Rights Agreement has
been amended so as to prevent holders of the Series A-1 Preferred and the
holders of the Series B Preferred from being deemed acquiring persons under the
Rights Agreement by virtue of their beneficial ownership of securities issued or
issuable in connection with the sale and issuance of Preferred Stock. The Rights
expire on July 25, 2005 or on their earlier exchange, redemption or expiration
in connection with certain permitted transactions.

beneficial ownership of the Company's Common Stock and Series B Preferred as of
December 31, 1997 by (i) each person or entity who is known by the Company to

B Preferred; (ii) each director of the Company; (iii) the Named Executive

     160,000 shares of the Company's Series A Preferred and the Series A Warrant
     to purchase an additional 140,000 shares of Series A Preferred. Fletcher
     exchanged such Series A Preferred for a like number of shares of Series A-1
     Preferred and exchanged the Series A Warrant for the Series A-1 Warrant to
     purchase a like number of shares of Series A-1 Preferred. The Series A-1
     Preferred is convertible into Common Stock of the Company based on a
     conversion rate that is dependent upon the trading price of the Company's
     Common Stock as reported on The Nasdaq Stock Market prior to the time of
     such conversion. As indicated above, on February 13, 1998, Fletcher
     exercised the Series A-1 Warrant with respect to 60,000 shares of Series
     A-1 Preferred and simultaneously converted 220,000 shares of Series A-1
     Preferred into 12,769,908 shares of Common Stock. Pursuant to the terms of
     the Subscription Agreement, the maximum number of shares of Common Stock
     issuable upon conversion of the Series A-1 Preferred (including upon
     exercise and conversion of the Series A-1 Warrant) was 13,674,500 as of
     December 31, 1997; however, on January 26, 1998, pursuant to the terms of
     the original financing agreements, Fletcher gave the Company a notice
     designating 16,674,500 shares as the maximum number of shares of Common
     Stock to be issuable upon conversion of the Series A-1 Preferred on or
     after April 1, 1998. Fletcher must give the Company another notice to
     increase the maximum number of conversion shares further. The Series A-1
     Preferred shares are non-voting securities and holders of Series A-1
     Preferred are not generally entitled to vote on corporate matters, prior to
     the conversion of such shares into Common Stock.

 (16) The Series B Preferred is convertible into Common Stock of the Company
      based upon the trading price of the Company's Common Stock as reported on
      The Nasdaq Stock Market. The Series B Preferred are non-voting securities
      and only shares of Common Stock issuable upon conversion of the Series B
      Preferred are entitled to vote on corporate matters. Generally, shares of
      Series B Preferred are first convertible on May 19, 1998. Upon conversion
      of the Series B Preferred, the holders of such Series B Preferred will be
      issued the Series B Warrants which will be exercisable immediately
      thereafter.
 
 (17) Based on an assumed Series B Preferred conversion price of $4.00, upon

      Series B Warrants, such holder would hold approximately 2.3% of the
      Company's outstanding Common Stock as of December 31, 1997, after taking
      into consideration the February 1998 issuance of 12,769,208 shares to

      Company's outstanding Common Stock as of December 31, 1997, after taking

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
       In June 1993, the Company made a loan in the principal amount of $150,000
to Myron (Mike) Saranga, the Company's Senior Vice President, Product Management
and Development, in connection with his accepting employment by the Company. The
loan is secured by a second deed of trust on residential real property acquired
by Mr. Saranga in California and was originally due and payable in full on the
earliest of June 2, 1995, the date Mr. Saranga sold certain residential real
property located in Connecticut, or the date Mr. Saranga's employment with the
Company was terminated. In June 1995, Mr. Saranga and the Company amended the
loan to increase the interest rate of 3.56% per annum to 6.55% per annum and to
provide that $30,000 of principal, and accrued interest, would be forgiven on
June 2, 1996 and each anniversary thereafter until the loan is no longer
outstanding, provided that Mr. Saranga remains an employee of the Company. The
loan continues to provide that the full amount of unpaid principal and accrued
interest will become immediately due and payable on the date Mr. Saranga's
employment with the Company is terminated for any reason. In June 1997 and June
1996, respectively, the Company forgave $35,568 and $39,825 of principal and
interest on the loan under the promissory note, respectively (such forgiveness
amounts were not grossed up to satisfy tax obligations). As of December 31,
1997, outstanding principal under the note totaled $90,000.

       In April 1997, the Company entered into Separation Agreements with Ronald
M. Alvarez, the Company's former Vice President, American Sales, and Edwin C.
Winder, the Company's former Vice President, Japan Operations, in connection
with their resignations as executive officers of the Company. Under the terms of
their respective Separation Agreements, Mr. Alvarez and Mr. Winder received
payments for six months additional salary from the time of their resignations at
the rate of $17,083.33 and $18,250.00 per month, respectively. In addition, Mr.
Alvarez received a bonus in the amount of $7,686.00 for his services during the
Company's first fiscal quarter of 1997. As part of his Separation Agreement,
options to purchase 11,250 shares of Common Stock of the Company held by Mr.
Alvarez continued to vest during the six months subsequent to his resignation
date. The Company also agreed to pay both Mr. Alvarez and Mr. Winder additional
fees for outplacement services and legal fees incurred in connection with the
negotiation of their respective Separation Agreements.
 
       In connection with D. Kenneth Coulter's resignation as Executive Vice
President, Worldwide Field Operations in July 1997, and pursuant to an
Employment Agreement the Company previously entered with Mr. Coulter, the
Company paid Mr. Coulter an aggregate of $106,954 over the five month period
ending December 31, 1997.
 
       In January 1997, the Company made a loan in the principal amount of
$150,000 to Alan Henricks, the Company's former Executive Vice President and
Chief Financial Officer, at an interest rate of seven percent (7.0%) per annum
in connection with his appointment as Chief Financial Officer. Under the terms
of the loan, $50,000 of principal would be forgiven on December 20 of each year
that Mr. Henricks remained an employee of the Company. In connection with Mr.
Henricks' resignation in April 1997, the Company entered into a Separation
Agreement with Mr. Henricks whereby the Company agreed to pay Mr. Henricks nine
months salary at a rate of $25,000.00 per month following his resignation. In
addition, Mr. Henricks agreed to repay the outstanding principal and interest
under the note in equal monthly installments of $17,156.00 through deductions
from Mr. Henricks' monthly severance payments described above.
 
       In connection with David H. Stanley's resignation as Vice President,
Legal and Corporate Services, and General Counsel in October 1997, the Company
entered into a Separation Agreement with Mr. Stanley whereby the Company agreed
to pay Mr. Stanley six months salary at a rate of $16,666.67 per month following
his resignation. In addition, the Company agreed that unvested options to
purchase up to an aggregate of 150,000 shares of Common Stock of the Company
held by Mr. Stanley would continue to vest during a one month transition period.
Under the Separation Agreement the Company also agreed to pay Mr. Stanley up to
$5,000 for outplacement services.
 
       The Company has made certain payments to Phillip E. White, the Company's
former Chairman, President and Chief Executive Officer in connection with his
resignation pursuant to the terms of an employment agreement between the Company
and Mr. White. See "Management--Employment Agreements and Change in Control
Arrangements."
 
       On November 17, 1997, the Company issued 160,000 shares of Series A-1
Preferred and the Series A-1 Warrant in cancellation of and exchange for all of
the outstanding Series A Preferred Stock and the Series A Warrant previously
issued in connection with a Subscription Agreement, dated August 12, 1997,
between Fletcher International Limited and the Company. The issuance of the
Series A-1 Preferred in exchange for the Series A Preferred was effected in
reliance on the exemption under Section 3(a)(9) of the Securities Act. On
February 13, 1998, Fletcher exercised the Series A-1 Warrant with respect to
60,000 shares of Series A-1 Preferred and simultaneously converted 220,000
shares of Series A-1 Preferred into 12,769,904 shares of Common Stock.
 
       In connection with the issuance of the Series B Preferred in November
1997, the Company paid The Shemano a fee of $1,000,000 for financial advisory
services provided in connection with such financing. In addition, the Company
issued Shemano 100,000 shares of its Common Stock. The Company also agreed to
issue Shemano a warrant to purchase up to an additional 50,000 shares of Common
Stock in
 
                                       66
<PAGE>
the event that, as of May 17, 1998, the trading price of the Company's Common
Stock is less than $12.50 (the "Shemano Warrant"). The Shemano Warrant is
exercisable according to the same terms as the Series B Warrants. In February
1998, the Company and Shemano entered a letter agreement pursuant to which the
Company agreed to repurchase from Shemano the 100,000 shares of Common Stock
issued in connection with the issuance of the Series B Preferred. The repurchase
price would be determined based on the then-prevailing price on The Nasdaq Stock
Market and would be payable in cash. The Company's obligation to repurchase such
shares will terminate upon the effectiveness with the Commission of a
registration statement covering such shares.
 
       Pursuant to both Article VI of the Company's Bylaws and Section 6 of the
Indemnification Agreement the Company enters into with its executive officers
and directors, the Company advances expenses incurred by indemnified parties in
connection with the investigation, defense, settlement or appeal of threatened,
pending or completed action or suits against such parties in their capacity as
an agent of the Company. Under both the Bylaws and the Indemnification
Agreement, the indemnified party will repay the Company for any advanced
expenses if it is ultimately determined that the indemnified party is not
entitled to be indemnified by the Company. See "Legal Proceedings" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Litigation." As of March 31, 1998, the Company has received invoices
for legal fees of approximately $1,075,000 incurred by certain of its current
and former executive officers and/or directors in connection with certain
actions and suits discussed in this report. As of the date of this report, the
Company has advanced approximately $540,000 in expenses to its former executive
officers and/or directors incurred in connection with such proceedings. The
Company anticipates advancing the remaining balance of such expenses in the near
future.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders--
Informix Corporation
 
       We have audited the accompanying consolidated balance sheets of Informix
Corporation as of December 31, 1997 and 1996, and the related consolidated
statements of operations, 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 financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Informix Corporation at December 31, 1997 and 1996, and the consolidated results
of its operations and its 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.

NOTE 1--RESTATEMENT OF FINANCIAL STATEMENTS
 
       Subsequent to the filing of its Annual Report on Form 10-K for the year
ended December 31, 1996 with the Securities and Exchange Commission, the Company
became aware of errors and irregularities that ultimately affected the timing
and dollar amount of reported earned revenues from license transactions in 1996,
1995 and 1994. The irregularities took numerous forms and were primarily the
result of lack of compliance with or circumvention of the Company's procedures
and controls.
 
       These errors and irregularities included unauthorized and undisclosed
arrangements or agreements between Company personnel and resellers, recognition
of revenue on certain transactions in reporting periods prior to contract
acceptance, the recording of certain transactions that lacked economic substance
and the recording of maintenance revenue as license revenue. The unauthorized
and undisclosed agreements with resellers introduced acceptance contingencies,
permitted resellers to return unsold licenses for refunds, extended payment
terms or committed the Company to assist resellers in selling the licenses to
end-users. Accordingly, license revenue from these transactions that was
recorded at the time product was delivered to resellers should have instead been
recorded at the time all conditions on the sale lapsed. Because of the
pervasiveness of the unauthorized arrangements with resellers in the 1994, 1995
and 1996 accounting periods, the Company concluded that all revenue from license
agreements with resellers in these accounting periods, except for thoses
licenses sold and billed on a per copy basis, should be recognized only when the
licenses were resold or utilized by resellers and all related obligations had
been satisfied. Amounts received from resellers as prepayments of software
license fees in advance of revenue recognition have been recorded as advances
from customers and financial institutions. This revised application of
accounting policy has been followed for all transactions with resellers, other
than those licenses sold and billed on a per-copy basis, for 1996, 1995 and
1994.
 
       Accordingly, such financial statements have been restated as follows:

       The nature of the Company's business in 1992 and 1993 was such that there
was not a material amount of revenues recorded under prepaid software license
transactions conducted with resellers during these years. Additionally, as a
result of the Company's extended procedures, there were no material errors or
irregularities identified affecting revenues recognized prior to the third
quarter of 1994. The Company concluded based on those circumstances that it was
not necessary to restate the financial statements for 1992 and 1993.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1--RESTATEMENT OF FINANCIAL STATEMENTS (CONTINUED)
       In response to the errors and irregularities discussed above, a number of
conditions which collectively represented a material weakness in the Company's
internal accounting controls were identified. These conditions included a
deterioration in the Company's accounting controls at corporate and regional
management levels, and a related failure to stress the importance of these
controls, an inappropriate level of influence, principally by the Company's
sales organization, over the revenue recognition process and an apparent lack of
clarity and consistent understanding within the Company concerning the
application of the Company's revenue recognition policies to large, complex
reseller license transactions. The Company is implementing a plan to strengthen
the Company's internal accounting controls. This plan includes updating the
Company's policies regarding accounting and reporting for large, complex
reseller license transactions, developing and conducting educational programs to
help implement such policies, changing the Company's corporate and regional
accounting and reporting structure, and re-establishing an internal audit
function reporting to the Company's Board of Directors.
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION AND OPERATIONS.  The Company is a multinational supplier of
high-performance, parallel processing database technology for open systems. The
Company's products also include application development tools for creating
client/server production applications, decision-support systems, ad-hoc query
interfaces, and software that allows information to be shared transparently from
personal computers to mainframes within the corporate computing environment. In
addition to software products, the Company offers training, consulting, and
post-contract support to its customers.
 
       The principal geographic markets for the Company's products are North
America, Europe, Asia/ Pacific, and Latin America. Customers include large-,
medium- and small-sized corporations in the manufacturing, financial services,
telecommunications, retail/wholesale, hospitality, and government services
sectors.
 
    USE OF ESTIMATES.  The preparation of financial statements in conformity
with general 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.
 
    PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements include
the accounts of Informix Corporation and its wholly owned subsidiaries. All
material intercompany balances and transactions have been eliminated in
consolidation.
 
    FOREIGN CURRENCY TRANSLATION.  For foreign operations with the local
currency as the functional currency, assets and liabilities are translated at
year-end exchange rates, and statements of operations are translated at the
average exchange rates during the year. Exchange gains or losses arising from
translation of foreign entity financial statements are included as a component
of stockholders' equity.
 
       For foreign operations with the U.S. dollar as the functional currency,
certain assets and liabilities are remeasured at the year-end or historical
exchange rates as appropriate. Statements of operations are remeasured at the
average exchange rates during the year. Gains and losses resulting from the
remeasurement of these foreign entity's financial statements and other foreign
currency transaction gains and losses are included in other income, net. Foreign
currency transaction gains, net of losses, were $8.0 million, $.3 million and
$.2 million for the years ended December 31, 1997, 1996 and 1995, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    DERIVATIVE FINANCIAL INSTRUMENTS.  The Company enters into forward foreign
currency exchange contracts to reduce its exposure to foreign currency risk due
to fluctuations in exchange rates underlying the value of firm accounts
receivable and accounts payable denominated in foreign currencies (primarily
European and Asian currencies) until such receivables are collected and payables
are disbursed. A forward foreign currency exchange contract obligates the
Company to exchange predetermined amounts of specified foreign currencies at
specified exchange rates on specified dates or to make an equivalent U.S. dollar
payment equal to the value of such exchange. These forward foreign exchange
contracts, to qualify as hedges of firm commitments, are denominated in the same
currency in which the underlying foreign receivables or payables are denominated
and bear a contract value and maturity date which approximate the value and
expected settlement date of the underlying transactions. For contracts that are
designated and effective as hedges, discounts or premiums (the difference
between the spot exchange rate and the forward exchange rate at inception of the
contract) are accreted or amortized to other expenses over the contract lives
using the straight-line method while unrealized gains and losses on open
contracts at the end of each accounting period resulting from changes in the
spot exchange rate are deferred and recognized in earnings in the same period as
gains and losses on the underlying foreign denominated receivables or payables
are recognized and generally offset. Contract amounts in excess of the carrying
value of the Company's foreign denominated accounts receivable or payable
balances are marked to market, with changes in market value recorded in earnings
as foreign exchange gains or losses. The Company does not enter into forward
foreign currency exchange contracts for speculative or trading purposes. If an
underlying hedged transaction is terminated earlier than initially anticipated,
the offsetting gain or loss on the related forward foreign currency exchange
contract is recognized in earnings in the same period. Subsequent gains or
losses on the related contract would be recognized in earnings in each period
until the contract matures, is terminated, or sold. The Company operates in
certain countries in Latin America, Eastern Europe, and Asia Pacific where there
are limited forward currency exchange markets and thus the Company has unhedged
transaction exposures in these currencies. However, such exposures are not
material to the Company's financial statements for any period presented.
 
    LICENSE REVENUE.  The Company recognizes revenue from sales of software
licenses to end-users upon delivery of the software product to the customer when
there are no significant post-delivery obligations and collection of the license
fee is considered probable. Revenue from license agreements with resellers,
except for those licenses sold and billed on a per-copy basis, is recognized as
earned when the licenses are resold or utilized by the reseller and all related
obligations have been satisfied. The Company provides for sales allowances on an
estimated basis.
 
    SERVICE REVENUE.  Maintenance contracts generally call for the Company to
provide technical product support and software updates to customers. Maintenance
contract revenue is recognized ratably over the term of the maintenance
contract, generally on a straight-line basis. Where maintenance revenue is not
separately invoiced, it is unbundled from license fees and deferred for revenue
recognition purposes. Other service revenue, primarily training and consulting,
is generally recognized at the time the service is performed.
 
    ADVANCES FROM CUSTOMERS AND FINANCIAL INSTITUTIONS.  At December 31, 1997
and 1996, "advances from customers and financial institutions" reflect amounts
received from customers and third-party financial institutions in advance of
revenue being recognized. The Company may receive cash, either from the
customer, or from a financing entity to whom the customer payment streams are
sold, prior to the time the license fee is recognized as earned revenue.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
       The Company's license agreements with customers provide contractually for
a non-refundable fee payable by the customer in single or multiple
installment(s) at the initiation or over the term of the license arrangement. If
the Company fails to comply with the contractual terms of a specific license
agreement, the Company could be required to refund to the customer or the
financial institution the amount(s) received. These terms require the Company to
meet all of its obligations under the license agreement; to have rights to the
software it licenses; to deliver software that is fully functional according to
agreement specifications; and to represent that the accounts receivable or
payment streams sold to the financial institution are payment obligations under
a valid, authorized, and legally enforceable contract between the Company and
customer. The refund of amounts received would not, however, have a material
effect on the Company's results of operation as revenue has not been recognized
for amounts recorded as "Advances from customers and financial institutions."
 
    SALES OF RECEIVABLES.  The Company often finances amounts due from customers
with financial institutions on a non-recourse basis. The Company accounts for
these transactions in accordance with Statement of Financial Accounting
Standards No. 77, "Reporting by Transferors for Transfers of Receivables with
Recourse (FAS 77). Effective January 1, 1998 these transactions will be
accounted for in accordance with Statement of Financial Accounting Standards No.
125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishment of Liabilities" (FAS 125). If at the time of the transfer the
amounts due from the customer have been recognized as revenue and a receivable,
the transfer is accounted for as the sale of a receivable and the receivable is
removed from the books and the financing fees are charged to operations
immediately as interest expense.
 
    SALES OF FUTURE REVENUE STREAMS.  If at the time of transfer the amounts due
from the customers have not been recognized as revenue or a receivable, the
transfer is accounted for as the sale of a future revenue stream in accordance
with EITF 88-18. Accordingly, the receipt of cash is treated as a borrowing and
recorded as "advances from customers and financial institutions" and the
financing fees are amortized to interest expense over the term of the financing
arrangement. The Company does not expect to finance amounts due from customers
subsequent to December 31, 1997.
 
    CONCURRENT TRANSACTIONS.  Principally during 1996, the Company entered into
software license agreements with certain computer and service vendors where the
Company concurrently committed to acquire goods and services in the aggregate of
approximately $130 million. If the agreement is with a reseller, revenue is
recognized as earned on these transactions as the licenses are resold by the
customer. If the agreement is with an end user, revenue is generally recognized
as earned upon delivery of software. The computer equipment and services are
recorded at their fair value. These concurrent transactions for 1996 included
license agreements of approximately $170 million. Concurrent transactions in
1997 included software license agreements of approximately $21 million and
commitments by the Company to acquire goods and services in the aggregate of
approximately $50 million (see Note 13).
 
    INVENTORIES.  Inventories, which consist primarily of software product
components, finished software products, and marketing and promotional materials,
are carried at the lower of cost (first in, first out) or market value, and are
included in other current assets.
 
    SOFTWARE COSTS.  The Company capitalizes software development costs incurred
in developing a product once technological feasibility of the product has been
determined. Software costs also include amounts paid for purchased software and
outside development on products which have reached technological feasibility.
All software costs are amortized as a cost of software distribution either on a
straight-line

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
basis over the remaining estimated economic life of the product or on the basis
of each product's projected revenues, whichever results in greater amortization.
Capitalized software costs are generally amortized over three years. The Company
recorded amortization of $21.4 million, $14.6 million, and $12.0 million of
software costs in 1997, 1996 and 1995, respectively, in cost of software
distribution.
 
    PROPERTY AND EQUIPMENT.  Depreciation of property and equipment is
calculated using the straight-line method over its estimated useful life,
generally the shorter of the applicable lease term or three-to-seven years for
financial reporting purposes.
 
    BUSINESSES ACQUIRED.  The purchase price of businesses acquired, accounted
for as purchase business combinations, is allocated to the tangible and
specifically identifiable intangible assets acquired based on their estimated
fair values with any amount in excess of such allocations being designated as
goodwill. Intangible assets are amortized over their estimated useful lives,
which to date have been five to seven years. The carrying values of goodwill and
specified intangible assets are reviewed if the facts and circumstances suggest
that they may be impaired. If this review indicates that the asset will not be
recoverable, as determined based on the undiscounted cash flows of the acquired
business over the remaining amortization period, the Company's carrying value is
reduced to net realizable value. During 1997, the Company wrote down $30.5
million of impaired long-term assets related to the shortfall in business
activity of its Japanese subsidiary (see Note 13). There were no writedowns of
intangible assets in 1996 or 1995. As of December 31, 1997 and 1996, the Company
had $19.2 million and $50.6 million of intangible assets, with accumulated
amortization of $10.9 million and $15.9 million, respectively, as a result of
these acquisitions.
 
    CONCENTRATION OF CREDIT RISK.  The Company designs, develops, manufactures,
markets, and supports computer software systems to customers in diversified
industries and in diversified geographic locations. The Company performs ongoing
credit evaluations of its customers' financial condition and generally requires
no collateral.
 
       No single customer accounted for 10% or more of the consolidated revenues
of the Company in 1997, 1996 or 1995.
 
    CASH, CASH EQUIVALENTS, SHORT-TERM INVESTMENTS, AND LONG-TERM
INVESTMENTS.  The Company considers liquid investments purchased with a maturity
of three months or less to be cash equivalents. The Company considers
investments with a maturity of more than three months but less than one year to
be short-term investments. Investments with an original maturity of more than
one year are considered long-term investments. Short-term and long-term
investments are classified as available-for-sale and are carried at fair value.
Cash equivalents are carried at amortized cost.
 
       The Company invests its excess cash in accordance with its short-term and
long-term investments policy, which is approved by the Board of Directors. The
policy authorizes the investment of excess cash in government securities,
municipal bonds, time deposits, certificates of deposit with approved financial
institutions, commercial paper rated A-1/P-1 (a small portion of the portfolio
may consist of commercial paper rated A-2/P-2), and other specific money market
instruments of similar liquidity and credit quality. The Company has not
experienced any significant losses related to these investments.
 
    SECURITIES HELD-TO-MATURITY AND AVAILABLE-FOR-SALE.  Management determines
the appropriate classification of debt securities at the time of purchase and
re-evaluates such designation as of each balance sheet date. Debt securities are
classified as held-to-maturity when the Company has the positive intent and the
 
                                      F-11

ability to hold the securities until maturity. Held-to-maturity securities are
stated at amortized cost, adjusted for amortization of premiums and accretion of
discounts to maturity. Such amortization, as well as any interest on the
securities, is included in interest income.
 
       Marketable equity securities and debt securities not classified as
held-to-maturity are classified as available-for-sale. Available-for-sale
securities are carried at fair value, with the unrealized gains and losses, net
of tax, reported in a separate component of stockholders' equity. The amortized
cost of debt securities in this category is adjusted for amortization of
premiums and accretion of discounts to maturity. Such amortization is included
in interest income. Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in other
expense, net. The cost of securities sold is based on the specific
identification method. Interest on securities classified as available-for-sale
are included in interest income. The Company realized gross gains of
approximately $8.5 million and $5.2 million and gross losses of approximately
$1.2 million and $1.3 million on the sale of available-for-sale equity
securities during 1997 and 1996, respectively. Realized gains and losses were
not material in 1995.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS.  Fair values of cash, cash equivalents,
short and long term investments, other assets, and currency forward contracts
are based on quoted market prices.
 
    RECLASSIFICATIONS.  Certain prior period amounts have been reclassified to
conform to the current period presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 4--DERIVATIVE FINANCIAL INSTRUMENTS
 
       The Company enters into forward foreign exchange contracts primarily to
hedge the value of accounts receivable or accounts payable denominated in
foreign currencies against fluctuations in exchange rates until such receivables
are collected or payables are disbursed. The purpose of the Company's foreign
exchange exposure management policy and practices is to attempt to minimize the
impact of exchange rate fluctuations on the value of the foreign currency
denominated assets and liabilities being hedged. Substantially all forward
foreign exchange contracts entered into by the Company have maturities of 360
days or less. The Company's practice is to settle all foreign exchange contracts
within ten calendar days of year end and thus there is no material difference
between the contract value and the fair value of the contracts at December 31,
1997 and 1996. At December 31, 1997 and 1996, the Company had approximately
$102.7 million and $168.6 million of forward foreign currency exchange contracts
outstanding, respectively. The table below summarizes by currency the
contractual amounts of the Company's forward foreign exchange contracts at
December 31, 1997 and December 31, 1996.
 
       The restatement of the 1996, 1995 and 1994 financial statements resulted
in a change in the Company's foreign currency denominated intercompany accounts
payable and accounts receivable balances. As a result, certain foreign currency
transaction gains and losses realized due to fluctuation in the related asset
and liability currency exchange rates were not offset by underlying gains and
losses on forward foreign currency exchange contracts used to hedge those
foreign currency exposures. The Company recorded net foreign currency
transaction gains and (losses) of approximately $7.5 million, $(0.7) million,
$0.1 million, and $(0.5) million in 1997, 1996, 1995, and 1994, respectively,
due to the restatement.

       While the contract amounts provide one measure of the volume of these
transactions, they do not represent the amount of the Company's exposure to
credit risk. The amounts (arising from the possible inabilities of
counterparties to meet the terms of their contracts) are generally limited to
the amounts, if any, by which the counterparties' obligations exceed the
obligations of the Company. The Company controls credit risk through credit
approvals, limits and monitoring procedures.
 
       As of December 31, 1997, other than foreign forward exchange contracts
discussed immediately above, the Company does not currently invest in or hold
any other derivative financial instruments.
 
NOTE 5--NET INCOME (LOSS) PER COMMON SHARE
 
    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 (FAS 128), "Earnings per Share." FAS
128 supersedes Accounting Principles Board Opinion No. 15 (APB 15), "Earnings
per Share," and other related Interpretations and is effective for the periods
ending after December 15, 1997. Under FAS 128, basic earnings per share are
computed using the weighted average number of common shares outstanding during
the period. Diluted earnings per common share includes the incremental shares
issuable upon the assumed exercise of stock options, warrants, and convertible
preferred stock, when the effect is dilutive. As required by FAS 128, all prior
year net income (loss) per share amounts have been restated.

       Weighted average employee stock options to acquire 4,776,124 and
6,263,000 were outstanding in fiscal 1997 and 1996, respectively, but were not
included in the computation of diluted earnings per share because the effect was
antidilutive. In addition, at December 31, 1997, 8,341,238 shares of convertible
preferred stock were also excluded from the computation of diluted earnings per
share because the effect was antidilutive. See Notes 6 and 7.
 
NOTE 6--PREFERRED STOCK
 
    In August 1997, the Company sold 160,000 shares of newly authorized Series A
Convertible Preferred Stock, face value $250 per share, which shares are
generally not entitled to vote on corporate matters, to a private investor for
aggregate net proceeds of $37.6 million and issued a warrant to the same
investor to purchase up to an additional 140,000 shares of Series A Convertible
Preferred Stock at an aggregate purchase price of up to $35 million. In November
1997, the Company canceled the Series A Convertible Preferred Stock in exchange
for the same number of shares of a substantially identical Series A-1
Convertible Stock (the "A-1 Preferred") issued to the same investor, with a
corresponding change to the warrant shares. The warrant may be exercised from
August 13, 1997 through April 15, 1999.
 
       The A-1 Preferred shares are convertible into common shares at any time,
at the holder's option, at a per share price equal to 101% of the average price
of the Company's common stock for the thirty days ending five trading days prior
to conversion, but not greater than the lesser of (i) 105% of the common stock's
average price of the first five trading days of such thirty day period, or (ii)
$12 per share. If not converted prior, the A-1 Preferred will automatically
convert into common shares eighteen months after their issuance, subject to
extension of the automatic conversion date in certain defined circumstances of
 
                                      F-16

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 6--PREFERRED STOCK (CONTINUED)
default. However, if at the time of conversion, the aggregate number of shares
of common stock already issued and to be issued as a result of the conversion of
the shares of the A-1 Preferred were to exceed 19.9% of the total number of
shares of then outstanding common stock, then such excess does not convert
unless or until stockholder approval is obtained.
 
       The mandatory redemption provisions of the new A-1 Preferred differ from
the Series A Convertible Preferred Stock. The redemption provisions in the A-1
Preferred effectively preclude the Company from having to redeem the preferred
stock except by actions solely within its control. Accordingly, the Consolidated
Balance Sheet reflects the A-1 Preferred under stockholder's equity. On February
13, 1998, the Series A-1 convertible preferred stockholders exercised their
conversion privileges. See Note 17--Subsequent Events.
 
       In November 1997, the Company sold 50,000 shares of newly authorized
Series B Convertible Preferred Stock ("Series B Preferred"), face value $1,000
per share, which shares are generally not entitled to vote on corporate matters,
to private investors for aggregate proceeds of $50.0 million (excluding a $1.0
million fee paid to a financial advisor of the Company). In connection with the
sale, the Company also agreed to issue a warrant to such investors upon
conversion of such Series B Preferred to purchase 20% of the shares of Common
Stock into which the Series B Preferred is convertible, but no less than
1,500,000 shares at a per share exercise price which is presently indeterminable
and will depend on the trading price of the Common Stock of the Company in the
period prior to the conversion of the Series B Preferred. The Company also
agreed to issue additional warrants to purchase up to an aggregate of 200,000
shares at a per share exercise price which is presently indeterminable and will
depend on the trading price of the Common Stock of the Company in the period
prior to the conversion of the Series B Preferred. The Series B Preferred is
convertible at the election of the holder into shares of Common Stock beginning
six months after issuance, and upon the occurrence of certain events, including
a merger. The Series B Preferred will automatically convert into Common Stock
three years following the date of its issuance. Each Series B Preferred share is
convertible into the number of shares of Common Stock at a per share price equal
to the lowest of (i) the average of the closing prices for the Common Stock for
the 22 days immediately prior to the 180th day following the initial issuance
date, (ii) 101% of the average closing price for the 22 trading days prior to
the date of actual conversions, or (iii) 101% of the lowest closing price for
the Common Stock during the five trading days immediately prior to the date of
actual conversion. The conversion price of the Series B Preferred is subject to
modification and adjustment upon the occurrence of certain events. The Series B
Preferred accrues cumulative dividends at an annual rate of 5% of per share face
value. The dividend is generally payable upon the conversion or redemption of
the Series B Preferred, and may be paid in cash or, at the holder's election, in
shares of Common Stock. The Series B is junior to the Company's outstanding A-1
Preferred in respect to the right to receive dividend payments and liquidation
preferences.
 
       The Company reserved 26.0 million shares of Common Stock for issuance
upon conversion of the A-1 Preferred (including shares of A-1 Preferred issuable
upon exercise of the Series A-1 Warrant). Of those 26.0 million shares, the
Company issued 12.8 million shares in February 1998 in connection with the
conversion of 220,000 shares of A-1 Preferred (see Note 17). The Company has
reserved 22.8 million shares of Common Stock for issuance upon conversion of the
Series B Preferred and upon exercise of the Series B Warrants.
 
       The fair value of the warrants issued in connection with the A-1
Preferred and Series B Preferred are deemed to be a discount to the conversion
price of the respective equity instruments available to the

preferred stockholders. The discounts are being recognized as a return to the
preferred stockholders (similar to a dividend) over the minimum period during
which the preferred stockholders can realize this return, immediate for the A-1
Preferred and six months for the Series B Preferred. The portion of the discount
applicable to fiscal 1997 has been accreted to additional paid in capital
(accumulated deficit) in the Company's December 31, 1997 financial statements
and has been disclosed as a decrease in the amount available to common
stockholders on the face of the statement of operations and for purposes of
computing net income (loss) per share. The fair value assigned to the warrants
is based on an independent appraisal performed by a nationally recognized
investment banking firm. The appraisal was completed utilizing the Black-Scholes
valuation model. This model requires assumptions related to the remaining life
of the warrant, the risk free interest rate at the time of issuance, stock
volatility, and an illiquidity factor associated with the security. These
assumptions and the values assigned to the Series A-1 and Series B warrants were
as follows:

       In connection with the issuance of the Series B Convertible Preferred
Stock in November 1997, the Company paid a fee of $1,000,000 for financial
advisory services provided in connection with such financing. In addition, the
Company issued 100,000 shares of its Common Stock, and also agreed to issue a
warrant to purchase an additional 50,000 shares of the Company's Common Stock to
the service provider in the event that, as of May 17, 1998, the trading price of
the Company's Common Stock is less than $12.50 per share. Such warrant will be
exercisable according to the same terms as the warrants issued in connection
with the issuance of the Series B Convertible Preferred Stock.
 
NOTE 7--EMPLOYEE BENEFIT PLANS
 
OPTION PLANS
 
       Under the Company's 1986 Employee Stock Option Plan, options are granted
at fair market value on the date of the grant. Options are generally exercisable
in cumulative annual installments over three to five years. Payment for shares
purchased upon exercise of options may be by cash or, with Board approval, by
full recourse promissory note or by exchange of shares of the Company's common
stock at fair market value on the exercise date. Unissued options under the 1986
Plan expired on July 29, 1996, which was 10 years after adoption of the plan.
 
       Additionally, 1,600,000 shares were authorized for issuance under the
1989 Outside Directors Stock Option Plan, whereby non-employee directors are
automatically granted non-qualified stock options upon election or re-election
to the Board of Directors. At December 31, 1997, 645,000 shares were available
for grant under this Plan.

NOTE 7--EMPLOYEE BENEFIT PLANS (CONTINUED)
       In April 1994, the Company adopted the 1994 Stock Option and Award Plan;
8,000,000 shares were authorized for grant under this Plan. Options can be
granted to employees on terms substantially equivalent to those described above.
The 1994 Stock Option and Award Plan also allows the Company to award
performance shares of the Company's common stock to be paid to recipients on the
achievement of certain performance goals set with respect to each recipient. In
May 1997, the Company's stockholders approved an additional 8,000,000 shares to
be reserved for issuance under the Company's 1994 Stock Option and Award Plan.
At December 31, 1997, 4,009,476 shares were available for grant under this Plan.
 
       In July 1997, the Company's Board of Directors approved a resolution
authorizing the grant of a maximum of 500,000 non-statutory stock options to
executives and other employees, as determined by the Board, under the newly
created 1997 Non-Statutory Stock Option Plan ("the 1997 Stock Plan"). The
authorization of such shares for grant under the 1997 Stock Plan is not subject
to stockholder approval. Terms of each option are determined by the Board or
committee delegated such duties by the Board. Concurrent with the authorization
of the 1997 Stock Plan, the Board granted the Company's current chief executive
officer 500,000 options to purchase the Company's common stock thereunder. Such
options vest ratably over five years beginning with the first anniversary of the
date of grant.
 
       In September 1997, the Company's Board of Directors authorized the
repricing of outstanding options to purchase Common Stock under the Company's
stock option plans. Employees were eligible to participate only if they remained
actively employed at the effective date of the repricing and were only permitted
to exchange options granted and outstanding prior to May 1, 1997. The
repricing/option exchange was effective November 21, 1997 (the "Repricing
Effective Date"). The repricing program offered eligible employees the
opportunity to exchange eligible outstanding options with exercise prices in
excess of the closing sales price of the Company's Common Stock on the Repricing
Effective Date for a new option with an exercise price equal to such price.
Other than the exercise price, each new option issued upon exchange has terms
substantially equivalent to the surrendered option, including the number of
shares, vesting terms and expiration except that options issued in connection
with the exchange may not be exercised for a period of one year from the
Repricing Effective Date. In addition, officers of the Company participating in
the option exchange were required to forfeit 20% of the shares subject to each
option being surrendered. The exercise price for repriced options was $7.1563,
the closing sales price of the Company's Common Stock on the Repricing Effective
Date.

three years ended December 31, 1997:

EMPLOYEE STOCK PURCHASE PLAN
 
       The Company also has a qualified Employee Stock Purchase Plan (ESPP)
under which 7,600,000 shares of common stock, in the aggregate, have been
authorized for issuance. Under the terms of the Plan, employees may contribute,
through payroll deductions, up to 10 percent of their base pay and purchase up
to 500 shares per quarter (with the limitation of purchases of $25,000 annually
in fair market value of the shares). Employees may elect to withdraw from the
Plan during any quarter and have their contributions for the period returned to
them. Also, employees may elect to reduce the rate of contribution one time in
each quarter. The price at which employees may purchase shares is 85 percent of
the lower of the fair market value of the stock at the beginning or end of the
quarter. The Plan is qualified under Section 423 of the Internal Revenue Code of
1986, as amended. During 1997, 1996, and 1995, the Company issued

573,343 shares, 616,128 shares, and 347,743 shares, respectively, under this
Plan. The Plan was terminated on July 1, 1997, which was 10 years after the
offering date for the Plan's first offering period.
 
       In May 1997, the Company's stockholders approved the 1997 Employee Stock
Purchase Plan (the "1997 ESPP"). The Company has reserved 4,000,000 shares of
Common Stock for issuance under the 1997 ESPP. The 1997 ESPP permits
participants to purchase Common Stock through payroll deductions of up to 15
percent of an employee's compensation, including commissions, overtime, bonuses
and other incentive compensation. The price of Common Stock purchased under the
1997 ESPP is equal to 85 percent of the lower of the fair market value of the
Common Stock at the beginning or at the end of each calendar quarter in which an
eligible employee participates. The Plan qualifies as an employee stock purchase
plan under Section 423 of the Internal Revenue Code of 1986, as amended. As of
December 31, 1997, the Company has not issued any shares of Common Stock under
the 1997 ESPP.
 
STOCK-BASED COMPENSATION
 
       As permitted under FASB Statement No. 123, "Accounting for Stock-Based
Compensation" (FAS 123), the Company has elected to continue to follow
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" (APB 25) in accounting for stock-based awards to employees. Under APB
25, the Company generally recognizes no compensation expense with respect to
such awards.
 
       Pro forma information regarding the net income (loss) and net income
(loss) per share is required by FAS 123 for awards granted or modified after
December 31, 1994 as if the Company had accounted for its stock based awards to
employees under the fair value method of FAS 123. The fair value of the
Company's stock-based awards to employees was estimated using a Black-Scholes
option pricing model.
 
       The fair value of the Company's stock-based awards was estimated assuming
no expected dividends and the following weighted-average assumptions:

NOTE 11--BUSINESS COMBINATIONS
 
       In February 1996, the Company acquired Illustra Information Technologies,
Inc. (Illustra), a company that provides dynamic content management database
software and tools for managing complex data in the Internet,
multimedia/entertainment, financial services, earth sciences and other markets.
Approximately 12.7 million shares of Informix common stock were issued to
acquire all outstanding shares of Illustra common stock. An additional 2.3
million shares of Informix common stock were reserved for issuance in connection
the assumption of Illustra's outstanding stock options and warrants. The
transaction has been accounted for as a pooling of interests, and accordingly,
the consolidated financial statements for all prior periods presented have been
restated to include the accounts and operations of Illustra as if the merger was
consummated at the beginning of the earliest period presented. Merger fees of
approximately $5.9 million were recorded in the first quarter of 1996. The
following table presents the separate operating results for Informix Corporation
and Illustra for the periods prior to the acquisition date (because the
operating results of Illustra for the period January 1, 1996 to the effective
date of the merger were immaterial to the combined Company, for the purposes of
this table an acquisition date of January 1, 1996 is assumed).

20 percent interest in January 1997. The total purchase price, which consisted
of cash and direct acquisition costs, was approximately $7.6 million, of which
approximately $7.0 million exceeded the net tangible assets acquired. Intangible
assets acquired included customer lists, sales and marketing workforce, business
tradenames, and goodwill. These intangible assets are being amortized over seven

       In February 1997, the Company acquired all of the outstanding capital
stock of CenterView Software, Inc. ("CenterView"), a privately-owned company
which develops and sells software application development tools. The aggregate
purchase price paid was approximately $8.7 million, which included cash and
direct acquisition costs. The transaction has been accounted for as a purchase
and, based on an independent appraisal of the assets acquired and liabilities
assumed, the purchase price has been allocated to the net tangible and
intangible assets acquired including developed software technology, acquired
workforce, in-process technology, and goodwill. The in-process technology, which
based on the independent appraisal has been valued at $7 million, had not, at
the date of acquisition, reached technological feasibility and had no
alternative future uses in other research and development projects.
Consequently, its value was charged to operations in the period the acquisition
was consummated (the first quarter of 1997). The remaining identifiable
intangible assets are being amortized over three to five years.
 
       The operating results of these businesses have not been material in
relation to those of the Company and are included in the Company's consolidated
results of operations from the date of acquisition.
 
NOTE 12--LITIGATION
 
    Commencing in April 1997, a series of class action lawsuits purportedly by
or on behalf of stockholders and a separate but related stockholder action were
filed in the United States District Court for the Northern District of
California. These actions name as defendants the Company, certain of its present
and former officers and directors and, in some cases, its independent auditors.
The complaints allege various violations of the federal securities laws and seek
unspecified but potentially significant damages. Similar actions were also filed
in California state court and in Newfoundland, Canada.
 
       Stockholder derivative actions, purportedly on behalf of the Company and
naming virtually the same individual defendants and the Company's independent
auditors, were also filed, commencing in August 1997, in California state court.
While these actions allege various violations of state law, any monetary
judgments in these derivative actions would accrue to the benefit of the
Company.
 
       Pursuant to Delaware law and certain indemnification agreements between
the Company and each of its current and former officers and directors, the
Company is obligated to indemnify its current and former officers and directors
for certain liabilities arising from their employment with or service to the
Company. This includes the costs of defending against the claims asserted in the
above-referenced actions and any amounts paid in settlement or other disposition
of such actions on behalf of these individuals. The Company's obligations do not
permit or require it to provide such indemnification to any such individual who
is adjudicated to be liable for fraudulent or criminal conduct. Although the
Company has purchased directors' and officers' liability insurance to reimburse
it for the costs of indemnification for its directors and officers, the coverage
under its policies is limited. Moreover, although the directors' and officers'
insurance coverage presumes that 100 percent of the costs incurred in defending
claims asserted jointly against the Company and its current and former directors
and officers are allocable to the individuals' defense, the Company does not
have insurance to cover the costs of its own defense or to cover any liability

for any claims asserted against it. The Company has not set aside any financial
reserves relating to any of the above-referenced actions.
 
       The pending federal and state securities actions are in the early stages
of discovery. Consequently, at this time it is not reasonably possible to
estimate the damages, or the range of damages, that the Company might incur in
connection with such actions. In addition, in July 1997, the Securities and
Exchange Commission issued a formal order of investigation of the Company and
certain unidentified individuals associated with the Company with respect to
non-specified accounting matters, public disclosures and trading activity in the
Company's securities. The Company is cooperating with the investigation and is
providing all information subpoenaed by the Commission.
 
NOTE 13--NONRECURRING CHARGES
 
    In accordance with Financial Accounting Standards Board Statement No. 121
(FAS 121), "Accounting for the Impairment of Long Lived Assets and for
Long-Lived Assets to be Disposed of," the Company records impairment losses on
long-lived assets used in its operations when events and circumstances indicate
that the assets might be impaired and the estimated future undiscounted cash
flows to be generated by those assets are less than the assets' carrying
amounts. During the first quarter of 1997, the Company's Japanese subsidiary
experienced a significant shortfall in business activity compared to historical
levels. Accordingly, the Company evaluated the ongoing value of the subsidiary's
long-lived assets (primarily computer and other equipment) and related goodwill.
Based on this evaluation, the Company determined that the subsidiary's assets
had been impaired and wrote them down by $30.5 million to their estimated fair
values. Fair value was determined using estimated future discounted cash flows
and/or estimated resale values as appropriate.
 
       In February 1997 the Company acquired CenterView Software (see Note 11)
and, as a direct result, revised its database application tool business strategy
to incorporate CenterView's developed technology and "Data Director" product.
This revision to the tools business strategy significantly altered the Company's
current and future marketing plans for its own NewEra family of application
tools including projected future NewEra product revenues. As a result, the
Company reevaluated the net realizable value of its NewEra products and found it
to be significantly below the net balance of related capitalized software
development costs. Accordingly, the Company recorded a charge during the first
quarter 1997 of $14.7 million to reduce the carrying value of these capitalized
product development costs to the revised estimated net realizable value of the
NewEra products.
 
       In June and again in September 1997, the Company approved plans to
restructure its operations in order to bring expenses in line with forecasted
revenues. In connection with these restructurings, the Company substantially
reduced its worldwide headcount and consolidated facilities and operations to

       Severance and benefits represent the reduction of approximately 670
employees, primarily sales and marketing personnel, on a worldwide basis.
Temporary employees and contractors were also reduced. Write-off of assets
include the write-off or write-down in carrying value of equipment as a result
of the Company's decision to reduce the number of Information Superstores
throughout the world, as well as the write-off of equipment associated with
headcount reductions. The equipment subject to the write-offs and write-downs
consists primarily of computer servers, workstations, and personal computers
that will no longer be utilized in the Company's operations. These assets were
written down to their fair value less cost to sell. The carrying value at
December 31, 1997 of computer equipment included in the restructuring activities
during the second and third quarters of 1997 and intended to be disposed of, is
approximately $2.2 million. Facility charges include early termination costs
associated with the closing of certain domestic and international sales offices.
 
       The total restructuring expense decreased by $1.2 million during the
fourth quarter of 1997 primarily due to adjusting the original estimate of the
loss to be incurred on the sale of land to the actual loss.
 
       The Company expects to complete most of the actions associated with its
restructuring by the end of the second quarter of fiscal 1998.
 
NOTE 14--SENIOR SECURED CREDIT AGREEMENT
 
    In December 1997, the Company entered into a Senior Secured Credit Agreement
with a syndicate of commercial banks, providing for a revolving credit facility
of up to $75 million (the "Credit Facility"). The actual amount available under
the Credit Facility, for either direct borrowings or issuances of letters of
credit, is based on certain eligibility criteria. As a result, the aggregate
amount available under the Credit Facility will vary from time to time based on
the amount and eligibility of the Company's receivables. As of December 31,
1997, no borrowings were outstanding under the Credit Facility, the Company's
net accounts receivable totaled $142 million and its borrowing base under the
Credit Facility was $47 million. The term of the Credit Facility is two years
and is secured by all of the assets of Informix Software and the capital stock
of the Company's domestic subsidiaries. The availability of the Credit Facility
is subject to the Company's compliance with certain covenants, including the
following financial covenants requiring the Company to: (a) maintain a ratio of
1.25 to 1.00 in respect of the sum of cash and acounts receivable to the
difference of current liabilities less deferred and unearned revenues, (b)
maintain quarterly revenues of

$150 million through June 1998 and $160 million thereafter, (c) maintain
quarterly operating loss of no more than $10 million through the quarter ending
March 31, 1998 and a quarterly operating profit of at least $10 million for the
quarter ending June 30, 1998 and a quarterly operating profit of at least $15
million thereafter, (d) maintain, for the quarter ending June 30, 1998 and each
quarter thereafter, a positive quarterly cash flow consisting of operating
income which does not include any restated revenue resulting from the Company's
November 1997 restatement of its financial statements, capitalized software
costs, capital expenditures or cash outlays in respect of accrued expenses
arising from restructuring charges (but which income figure does take into
account depreciation and amortization expenses), (e) maintain an interest
coverage ratio of 1.25 to 1.00 in respect of quarterly operating cash flow to
interest expense plus scheduled amortization of debt, (f) refrain from making
additional investments in fixed or capital assets, in any fiscal year, in excess
of $15 million, plus any carry forward amount which carry forward amount cannot
exceed $5.0 million, and (g) refrain from entering into any merger,
consolidation, reorganization or other transaction resulting in a fundamental
change. At December 31, 1997, the Company was in compliance with all financial
covenants under the Credit Facility.

    $1.2 million during the fourth quarter of 1997 primarily due to adjusting
    the original estimate of the loss to be incurred on the sale of land to the
    actual loss. (See Note 13)
 
(2) In the first quarter of 1997, the Company recorded a charge of $30.5 million
    to write down the carrying values of certain of its Japanese subsidiary's
    long-lived assets to their fair values. During the same quarter, the Company
    also recorded a charge of $14.7 million to write down the carrying value of
    capitalized software development costs for certain products to their net
    realizable values.
 
NOTE 16--RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (UNAUDITED)
 
    In 1997, the American Institute of Certified Public Accountants issued
Statement of Position 97-2 (SOP 97-2), "Software Revenue Recognition" as amended
by Statement of Position 98-4 (SOP 98-4). The Company will be required to adopt
the provisions of the SOPs' as of January 1, 1998. The adoption may, in certain
circumstances, result in the deferral of software license revenues that would
have been recognized upon delivery of the related software under preceding
accounting standards. In response to these SOPs', the Company will likely change
its business practices, and, consequently, the Company cannot quantify the
effect the SOPs' will have on its operating results, financial position or cash
flows.
 
       In June 1997, the Financial Accounting Standards Board issued Statement
No. 130, Reporting Comprehensive Income (FAS No. 130) and Statement No. 131,
Disclosures About Segments of An Enterprise and Related Information (FAS No.
131). FAS No. 130 establishes rules for reporting and displaying comprehensive
income. FAS No. 131 will require the Company to use the "management approach" in
disclosing segment information. Both statements are effective for the Company

130 or FAS No. 131 will have a material impact on the Company's results of
operations, financial position or cash flows.
 
NOTE 17--SUBSEQUENT EVENTS (UNAUDITED)
 
    In December 1997, the Company's Board of Directors authorized a second
option repricing which was effective January 9, 1998 (the "Second Repricing
Effective Date") based upon the closing sales price of the Company's Common
Stock as of the Second Repricing Effective Date. Under the terms of the second
repricing, each employee, excluding officers and directors of the Company, could
exchange any option granted and outstanding as of May 1, 1997 for a new option
with an exercise price equal to the closing sales price on the Second Repricing
Effective Date and with terms consistent with those of the original option,
except that options exchanged in the second repricing could not be exercised for
a period of one year from the Second Repricing Effective Date. The exercise
price for repriced options was $5.094, the closing sales price of the Company's
Common Stock on the Repricing Effective Date.
 
       On February 13, 1998, the A-1 Preferred Stockholders exercised warrants
to purchase 60,000 additional shares of A-1 Preferred at $250 per share for net
proceeds to the Company of $14.1 million, and simultaneously converted 220,000
shares of A-1 Preferred into 12,769,908 shares of the Company's common stock.
