ITEM 1.  BUSINESS
 
     Tandem Computers Incorporated, a Delaware corporation founded in 1974,
designs, develops, manufactures, markets, and supports a full range of
entry-level to high-end systems that are utilized for online transaction
processing (OLTP), decision support, and messaging applications. (The terms
"Tandem" and the "Company" used throughout this document refer to Tandem
Computers Incorporated or Tandem Computers Incorporated together with its
consolidated subsidiaries, as required by the context.) Tandem has two primary
product families, the NonStop(R) family of systems and servers and the Integrity
family of fault-tolerant UNIX(R) System V, Release 4 (SVR4)-based systems.
Tandem also provides networking products through its Ungermann-Bass Networks,
Inc. (UB Networks), subsidiary.
 
     During 1994, Tandem continued to enhance its most recent line of NonStop
parallel servers, the Himalaya server range, which offers customers all of the
fundamental advantages of Tandem systems -- namely fault tolerance, data
integrity, linear expandability, and full application compatibility with
previous generations of NonStop systems -- while providing customers with
greatly improved price/performance. The Himalaya range incorporates
industry-standard reduced instruction set computing (RISC) microprocessors.
Volume shipments of Tandem's high-end Himalaya K10000 server began in December
1993.
 
     During 1994, Tandem also extended its Integrity family of binary compatible
UNIX SVR4-based systems with new models employing faster processors.
Specifically, the Integrity 1455 and 1475 models were introduced using the
MIPS(R) R4400(TM) 100-MHz and 150-MHz microprocessors, respectively.
 
     Tandem's target customers are primarily Fortune 1000 companies and other
large, diversified concerns that require online applications for critical
business functions. Tandem's customers use Tandem systems to gain better control
over resources, offer improved goods and services, receive better and more
timely management information, and reduce costs. The Company's products are used
worldwide in a number of governmental agencies and in over 25 industries,
including business services, communications, banking, financial services,
manufacturing, wholesale and retail distribution, and transportation.

NONSTOP SYSTEMS AND SERVERS
 
     Tandem's NonStop systems and servers support demanding online transaction
processing requirements, business-critical applications, and decision support
systems.
 
     NonStop systems and servers deliver reliability through hardware and
software fault tolerance and data integrity. NonStop systems and servers have a
parallel architecture, which delivers various levels of system performance.
Using processors in parallel allows multiple units of work to be reliably and
simultaneously completed. All NonStop systems and servers allow substantially
linear expansion of processing power within a single system by the addition of
processors, enabling the user to expand the system's transaction processing
capacity without sacrificing the initial investment in hardware and software.
 
     The Himalaya range of parallel servers delivers outstanding
price/performance for business applications. These applications require
reliability, high performance, openness, and scalability, which is delivered by
the combination of the Himalaya hardware and NonStop Kernel software. The
Himalaya servers connect to a wide range of client platforms and operating
systems, including Microsoft Windows, MS-DOS, OS/2, SCO UNIX, SunOS, HP UX,
Microsoft Windows NT, and Apple System 7. NonStop Himalaya servers also support
a wide range of open database gateways and a variety of open networking
standards, including TCP/IP, NETBIOS, AppleTalk, SNA, and OSI. NonStop Himalaya
servers also support portability requirements through their UNIX personality,
which began delivery in 1994 with software developer toolkits.
 
Hardware
 
     The Himalaya range comprises three systems. The K100, Tandem's entry-level
parallel server, based on NonStop CLX/R hardware, is expandable and is available
with processors based on complex instruction set computing (CISC) or RISC
microprocessor technology. The K1000 scalable parallel server is a midrange
server providing a wider range of scalability and connectivity. The K10000
massively parallel commercial server is the most powerful product ever built by
Tandem and uses the MIPS R4400 microprocessor. The K10000 is scalable from 2 to
over 4,000 processors, and enables Tandem customers to run their largest
business applications at peak performance.
 
     Tandem continues to offer NonStop CLX 800, CLX/R, Cyclone, and Cyclone/R
systems.
 
Software
 
     In 1994, Tandem continued the rollout of its NonStop Kernel software, a new
version of its modular operating system for NonStop servers that consists of the
core operating system (the kernel) plus extensions of software layers that add
functionality and operating environments or "personalities." Tandem offers a
Guardian personality with NonStop Kernel software that is completely compatible
with previous versions of the Guardian operating system running on NonStop
systems. NonStop Kernel software also features a UNIX personality, allowing
customers to use applications written using open application program interfaces
(APIs) on NonStop servers.
 
     NonStop Kernel software delivers the functionality required for OLTP and
messaging applications, including multiprogramming, parallel processing,
network-oriented software, reliability, and openness. NonStop Kernel software
provides a means of recognizing and responding to hardware or software failure,
scheduling application programs according to assigned priorities, allocating
system resources among different programs, communicating with peripheral
devices, handling communications between programs, and allowing expansion or
contraction of a system without reprogramming application software.
 
     Tandem's NonStop Kernel software is designed to keep applications running
through any single failure. If a processor fails, work is automatically
redirected to other processors in the system. Inherent in a NonStop
 
                                        3
<PAGE>   4
 
system or server is the capability to maintain duplicate data automatically on
two separate disk drives. If a failure occurs in one of the disk drives, access
to the database can continue without interruption of the application. When the
failed disk drive is repaired, the NonStop Kernel updates and restores the data
of the repaired disk drive without disrupting the ongoing functions of the
application.
 
     To provide fault-tolerant capabilities, a software process can have a
backup process running on the NonStop server. If the primary process stops
because of a hardware or software failure, the backup process is able to take
over and continue operation. In addition, whenever a hardware or software
failure is indicated, NonStop processors are immediately taken out of service,
providing the highest degree of data integrity possible during system operation.
They are returned to service after repair, prepared to resume operation and
accept processing tasks.
 
     In 1994, Tandem announced several new releases. The new NonStop SQL product
is named NonStop SQL/MP; the new Pathway transaction monitor is named NonStop
Transaction Services/MP (NonStop TS/MP); and the Transaction Monitoring Facility
(TMF) is now NonStop Transaction Manager/MP (NonStop TM/MP). These new products
are planned for delivery with the next version of the NonStop Kernel (Version 2)
operating system scheduled for fiscal 1995 shipment.
 
     Tandem's NonStop SQL/MP software is an improved version of NonStop SQL, a
high-performance distributed relational database management system incorporating
the industry-standard structured query language (SQL). Fully integrated into the
NonStop Kernel operating system, NonStop SQL software was the first relational
model to provide not only the performance needed for high-volume OLTP, but also
transparent data distribution. Data anywhere in a network of NonStop servers can
be read, written, or updated with full transaction protection so that the
database consistently reflects the current state of a business. The current
version of NonStop SQL/MP software provides simultaneous parallel query, batch,
and online transaction processing and allows the user to reorganize portions of
the database while the production database remains online. The advanced database
features delivered in NonStop SQL/MP have exploited the parallel architecture
for complex tasks such as decision support queries. These features have enabled
Tandem to offer decision support systems that provide very rapid query
turnaround time.
 
     An integral part of NonStop Kernel software is Tandem's NonStop TM/MP
software, designed to maintain the consistency of a central or a distributed
database. Applications running on NonStop systems that use NonStop TM/MP
software can automatically recover from all single-component failures, most
multiple-component failures, and all system failures. When the system comes back
online, any partially complete transactions are backed out on all nodes of a
distributed network, ensuring that the database accurately reflects the current
state of the business at the time of the failure.
 
     Tandem's Remote Duplicate Database Facility (RDF) software maintains a
duplicate copy of a database at a designated backup or remote site using
standard communications lines, enabling users to implement a disaster recovery
plan that can bring applications back online within minutes should an entire
computer facility become damaged or inaccessible.
 
     To provide a more open environment and to facilitate software development
for Tandem systems and servers, the Company offers a variety of software tools
for the development of online application programs. Tandem has formed
relationships with selected vendors to make their tools available on NonStop
systems. Examples of these product offerings are Texas Instruments,
Incorporated's IEF (Information Engineering Facility) products and MicroFocus's
Cobol Workbench software.
 
     Tandem is continuing its work with Novell, Inc., to provide the TUXEDO(R)
Enterprise Transaction System with NonStop Kernel software. The resulting
product, to be called NonStop TUXEDO, will be an open transaction monitor for
business-critical client/server solutions delivering reliability and
scalability. With NonStop TUXEDO, open systems software vendors that deploy
their transaction processing applications on Tandem servers will enhance their
offerings through the use of Tandem fundamentals.
 
     NonStop Kernel software also provides capabilities for client/server
applications. The Remote Server Call (RSC) product provides access to NonStop
servers from UNIX, DOS, OS/2, and Windows client platforms. The ODBC product
provides access to NonStop SQL databases from many Microsoft Windows
 
                                        4
<PAGE>   5
 
applications. In addition, applications can be developed for the NonStop server
from a wide range of popular Windows based tools, such as PowerBuilder and
Visual Basic.
 
INTEGRITY SYSTEMS
 
     The Integrity systems family is designed to extend Tandem strengths,
including data integrity and fault tolerance, to the market for UNIX SVR4-based
systems and to complement the Company's NonStop systems and servers.
 
     The hardware of the Integrity FT systems family is such that no single
failure will cause the system to stop operating. The architecture is based on a
main processing complex consisting of three loosely synchronized CPU modules
operating as one triple modular redundant processor. If the output from one CPU
module is different from the other two, voting logic and the NonStop-UX
operating system software are able to detect and isolate the faulty CPU module,
allowing processing to continue using the other two CPU modules. The NonStop-UX
operating system software automatically tests the faulty CPU module,
reintegrating it into the system if the failure was caused by a nonreproducible
error or reintegrating a replacement CPU after the faulty CPU has been replaced.
Data integrity and application processing are maintained throughout.
 
     In addition to offering hardware fault tolerance, data integrity, mirrored
disks, and protection against power failure, Integrity FT systems extend fault
tolerance to an industry-standard, VMEbus-compatible I/O subsystem. Integrity FT
systems are available for either commercial or telecommunications central office
environments and can be serviced online by users, lowering cost of ownership.
 
     During 1994, Tandem extended the Integrity FT systems family with the
introduction of the high-end CM-1475 and CO-1475 models, which feature increased
system performance at the same price as the earlier 1450 models. Also during
1994 two new, lower-priced entry-level models were introduced: the 300LC, which
provides a low-cost entry point to full fault tolerance based on the
R3000(R)MIPS microprocessor; and the CM-1400E, which provides an entry-level
R4000(R)based machine which can later be upgraded to the CM-1475 performance
level through the purchase of upgrade options.
 
     In addition to the Integrity FT systems family of fault-tolerant systems,
Tandem continues to offer a complete line of non-fault-tolerant UNIX systems,
the Integrity NR series. This product line spans the range from low-level
workstation products such as the Indy(TM) and Indigo(R), to highly scalable
symmetric multiprocessing servers. In addition to the workstation models, the
line currently consists of the NR/4001, a uniprocessor server; the NR/4412, a
midrange server that supports up to 12 processors; and the NR/4436, which
supports up to 36 processors. All of these systems run the UNIX operating system
and provide application compatibility with the Integrity FT line.
 
     Tandem offers the NonStop-UX operating system, which is based on UNIX SVR4
from Novell, Inc. The NonStop-UX operating system conforms to the System V
Interface Definition (SVID), the IEEE POSIX standards, the X/Open Portability
Guide, base profile standard, and the MIPS ABI standard. This makes it possible
for thousands of existing UNIX applications to be made available to Integrity
system users. Integrity systems support application development tools and
databases from a variety of independent software vendors.
 
PERIPHERALS
 
     Tandem offers a complete line of peripherals for use with its systems and
servers. In 1994 Tandem introduced a new generation of modular disk subsystems
based on high capacity 3.5-inch disk technology. This new product, the 4560,
offers a modular stackable range of disks that enable a customer to concentrate
over 150 gigabytes in less than 6 square feet of floor space. The 4560 replaced
the previous 4500 and 4510 disk products. However, existing customers can add
the 4560 to their existing 4500/4510 complexes.
 
     The Company also offers quality industry-standard products, including
workstations, servers, terminals, and a variety of printing products, through
original equipment manufacturer (OEM) and value-added reseller (VAR)
relationships. The Company adds hardware and software enhancements to several of
these products prior to resale.

NETWORKING, COMMUNICATIONS, AND NETWORK MANAGEMENT
 
     Tandem offers an extensive range of LAN and wide area network (WAN)
hardware and software products. Tandem's networking products enable NonStop and
Integrity systems to participate in complex multiprotocol networks employing a
variety of industry-standard protocols, including SNA, TCP/IP, OSI, AppleTalk,
and NETBIOS. Tandem communications products allow NonStop systems and servers to
connect directly to a variety of transaction-generating devices such as
terminals, workstations, automated teller machines, cash registers, and bar-code
readers.
 
     Extending its NonStop technology, in October 1993 Tandem introduced the
NonStop Access product line in a joint development between the NonStop Systems
Division and UB Networks. From this development it is now possible to supply
continuous networking from a Himalaya server to a client (PC) device through the
provision of dual paths from the server to the client. UB Networks supplies a
special card that is plugged into the workstation and maintains two links from
this card through its Access/One hub technology to the Himalaya server. In the
event that one of the links becomes unavailable, networking continues without
interruption to the client applications and without loss of transactions.
 
     Geographically dispersed NonStop systems can be connected in a distributed
network using Expand networking software. With Expand software, NonStop programs
in different systems can access data files and can communicate transparently as
if they were in the same system. Expand software enables Tandem NonStop systems
and servers to be interconnected via industry-standard protocols.
 
     Tandem offers a variety of network management tools to facilitate efficient
management of Tandem NonStop systems being managed in an open environment.
Distributed Systems Management (DSM) software provides an architecture and set
of services that permit the management of remote systems and business
applications. DSM software can be tailored according to the user's needs to
support either centralized or decentralized management of operations and
provides the foundation for automated operations at central or remote sites.
 
UB Networks
 
     Through UB Networks, Tandem provides complete communications solutions,
ranging from departmental to enterprise-wide networks. UB Networks offers a full
line of networking products, including modular and stackable hubs, high-speed
concentrators, internetworking products, and adapter cards. These hardware
products are supported by a standards-based network management platform that
provides comprehensive fault, configuration, accounting, performance, and
security management for complex, multivendor networks. In addition, UB Networks
offers VNA (Virtual Network Architecture), a network architecture that improves
the performance and flexibility of networks. In 1994, UB Networks announced its
ATM/Anywhere strategy and product offering, which will provide an evolutionary
migration path to ATM (Asynchronous Transfer Mode) that allows customers to
cost-effectively incorporate ATM functionality into their existing networks.

connectivity, interoperability, and portability. The Company expects to
introduce additional new products in the future.
 
MARKETING, SALES, AND SUPPORT
 
     The Company markets its products primarily through its own organization,
comprising marketing, sales, training, field service, and software support
personnel. Tandem also markets its products through distributors, VARs, and
OEMs. The Company's products are installed in over 60 countries worldwide. The
Company intends to increase its market share through alternate channels of
distribution, both within the U.S. and internationally. In addition, the Company
is pursuing extension of its business into new geographies where it intends to
appoint additional channel resellers.
 
     Applications are typically developed by the customer's own programmers or
are provided by applications software providers and resellers. To facilitate the
development and availability of applications on Tandem systems, the Company
established the Tandem Alliance Program with selected VARs, software houses,
systems integrators, and other related businesses. Through the Alliance Program,
the Company offers Alliance members a variety of licensing, marketing,
technical, and sales support programs. More than 300 Alliance members work with
Tandem to develop solutions for customers in a wide range of industries.
 
     To enhance its international marketing, sales, and support efforts, Tandem
has established joint ventures in Chile, Japan, Mexico, Singapore, China, and a
number of European countries. The Company's joint ventures in Chile and Mexico
distribute and support Tandem products. Other joint ventures provide project
management and contract consulting services to Tandem customers and develop and
support customized application software to meet the needs of the local
marketplace. They may also assist Tandem Alliance members with the distribution
and support of their software products.
 
     The Company has established OEM and reseller relationships with several
vendors, including AT&T; Silicon Graphics, Inc.; Cabledata; Motorola, Inc.;
Sprint International; Nippon Telephone and Telegraph (NTT); Singapore Telecom;
and British Telecommunications, plc., to increase its marketing efforts. Tandem
has also established marketing relationships with leading systems integrators
such as Andersen Consulting, Logica plc, and Electronic Data Systems
Incorporated.
 
     During 1994, over 80 percent of the Company's hardware sales were to end
users. The remaining sales were to distributors and to resellers that add their
hardware and software products for specific applications. No customer accounted
for 10 percent or more of the Company's total 1994 revenues.
 
                                        7
<PAGE>   8
 
     The Company strives to minimize the time between the receipt of orders and
the shipment of systems. Typically, the Company ships systems to a customer
within 90 days of receiving the order. For this reason, and because of the
possibility that customers could change delivery schedules or cancel orders, the
order backlog at any particular date may not be representative of the Company's
actual sales for any succeeding fiscal period.
 
     The Company also offers a leasing program to its customers. Reference is
made to the information under the caption "Leasing Program" in the Notes to
Consolidated Financial Statements on pages 28 and 29.
 
     Tandem offers professional services and education, including design
consulting, systems integration, operations management guidance, and system
requirements planning. Tandem's support centers can remotely perform system
diagnostics of both hardware and software. The Company also offers on-site
service.
 
     Because many OLTP solutions are similar across different businesses and
industries, Tandem's Program Sales Teams provide customers with complete
solutions to specific OLTP requirements, decision support, and client/server
needs. These teams market and sell solutions that can be easily adapted or
transported across industries, such as imaging, EDI, messaging, smart phones,
and call centers.
 
     NonStop Himalaya, NonStop Cyclone, NonStop Cyclone/R, NonStop CLX, NonStop
CLX/R, and Integrity systems, certain storage systems, and UB Networks'
networking hardware products are covered by one-year service warranties. The
Company generally provides 90-day warranties on other products. After the
warranty period, the Company offers maintenance service under contract. A
substantial portion of customers have maintenance contracts with the Company.

     The market for OLTP computer systems is highly competitive. Important
considerations for potential purchasers include price/performance and cost of
ownership, openness, system capability, availability, expandability,
compatibility, reliability and maintainability, and the capability of a
manufacturer to develop new products and enhance existing products. Tandem
believes that, with the introduction of the Himalaya range, it competes
favorably with respect to these factors.
 
     Tandem systems compete with those of three classes of competitors.
Competitors for traditional NonStop systems include IBM, Digital Equipment
Corporation (DEC), and Stratus Computer, Inc. (Stratus). The new pricing and
open features of the Himalaya range position it in a broader market and against
a wider range of competitors, including Sequent Computers, Inc. (Sequent), Sun
Microsystems, Inc. (Sun), and Hewlett Packard Company (HP). Certain massively
parallel configurations of NonStop servers are competitive with products from
other providers of parallel systems. Recent increased industry focus on
commercial parallelism has placed Tandem in competition with non-traditional
competitors. Specifically, in parallel database applications such as decision
support, Teradata (owned by AT&T) is now a competitor.
 
     The Integrity product family competes with UNIX offerings from Stratus,
Sequent, Sun, HP and IBM.
 
     In the highly competitive LAN market, UB Networks faces substantial
competition from several established and emerging computer communications and
LAN companies. Because UB Networks competes in multiple product markets, it
faces an array of competitors, including IBM, DEC, Cabletron Systems, SynOptics,
3Com Corporation, Chipcom, and Cisco Systems, Inc.
 
     The computer industry is characterized by rapid technological advances. To
remain competitive, computer companies must pursue technical development.
Accordingly, the Company continues to incur substantial engineering and software
development expenses. During 1994, 1993, and 1992, the Company's research and
development expenses were $269.3 million, $313.3 million, and $285.1 million,
respectively. Reference is made to the information found under the caption
"Software Development Costs" in the Notes to Consolidated Financial Statements
on page 24.
 
MANUFACTURING
 
     In general, the Company assembles its systems from components and
prefabricated parts manufactured by others. A number of the custom and
semicustom integrated circuits, printed circuit boards, and power
 
                                        8
<PAGE>   9
 
supplies are manufactured by others to the Company's specifications. Tandem
purchases terminals, workstations, printers, disk drives, tape drives, cable
assemblies, power supplies, and other subassemblies and peripheral equipment.
Manufacture of Tandem computer systems requires the assembly and testing of
integrated circuits, circuit boards, peripheral subsystems, power supplies, and
other items, as well as the final assembly, integration, and testing of
completed computer systems. All inspection functions, final assembly, and system
integration tests are performed by Company personnel. The Company's
manufacturing facilities are located in Santa Clara County, California, and in
Stirling, Scotland.
 
     From time to time, the Company has experienced quality problems with
components purchased from its suppliers. Most of the components and peripherals
used in the Company's systems are available from a number of different
suppliers. The Company believes that alternative sources could be developed, if
required, for present single-sourced components or peripherals. Although the
Company has not experienced any significant problem in obtaining its required
supplies, future shortages of components or peripherals could result in
production delays that could adversely affect business.
 
ENVIRONMENTAL REGULATIONS
 
     The Company's objectives include providing products and services that are
environmentally sound, and conducting business operations in an environmentally
responsible manner. Compliance with federal, state, and local provisions
relating to the discharge of materials into the environment, or otherwise
relating to the protection of the environment, by the Company has not had, nor
is expected to have, a material effect on the capital expenditures, earnings, or
competitive position of the Company.
 
PATENTS
 
     Tandem has been awarded patents in the United States and some foreign
countries on various aspects of its computer systems. Additional patent
applications are pending in the United States and certain foreign countries.
There can be no assurance that any of these applications will result in the
award of a patent or that the Company would be successful in asserting its
patent rights in any subsequent infringement actions. The patents and patent
applications, although of significant value to the Company, are not considered
to be of material importance to the business as a whole.
 
     Because of the existence of a large number of patents in the computer field
and the rapid rate of issuance of new patents, it is not economically practical
to determine in advance whether a new product or any of its components infringe
any patent. Some of the Company's products have been alleged to infringe patents
and additional allegations may be made in the future. In the event of an
infringement, the Company believes that, based on industry practice, any
necessary licenses or rights under such patents may be obtained on terms that
would not have a material adverse financial effect on the Company.
 
EMPLOYEES
 
     As of September 30, 1994, the Company had 8,466 full-time equivalent
employees.

ITEM 2.  PROPERTIES
 
     The Company is headquartered in Cupertino, California, where it owns 18 and
leases three buildings totaling approximately 1.5 million square feet.
Approximately 60 percent of the space is devoted to manufacturing and product
development functions, while the remaining 40 percent houses marketing and
administration. Tandem leases four additional facilities in Northern California,
comprising approximately
 
                                        9
<PAGE>   10
 
186,000 square feet, which are devoted to product development, marketing, and
administration, or one or more of those functions.
 
     Tandem has implemented a program to create a permanent headquarters complex
in Cupertino. As part of this program, the Company plans to develop, at a future
date, the 5.4 acre parcel that it purchased in 1988. In addition, during 1990,
the Company purchased, as a package, 16 parcels of improved and unimproved
property totaling 92 acres, and a retail shopping complex, near its Cupertino
headquarters. The additional space will allow for expansion and for relocation
of employees located in other Santa Clara County, California, facilities. The
Company recently leased and is renovating approximately 490,000 square feet in
Fremont, California, where it will consolidate all U.S. manufacturing during
1995. In 1994, Tandem sold two sites in Cupertino, California, a 15 acre parcel
and a 3.3 acre parcel.
 
     The Company leases a facility devoted to development, marketing, and
administration in Plano, Texas; and facilities that are primarily dedicated to
manufacturing in Sunnyvale and Santa Clara, California. In 1993, the Company
acquired a manufacturing facility in Stirling, Scotland. In addition, Tandem
owns a product development facility of approximately 190,000 square feet in
Austin, Texas. The Company also leases sales, field service, and training
offices at more than 150 locations in North America, Europe, Asia, and the
Pacific Rim. In 1988, Tandem entered into a prepaid 999 year lease for property
near London that serves as its United Kingdom headquarters.

OPERATING RESULTS
 
REVENUES
 
Total revenues in 1994 of $2.1 billion increased 4 percent over 1993, but
increased 8 percent excluding the effects of business units sold. Product
revenues for 1994, with and without business units sold, increased 4 percent and
9 percent, respectively, over 1993. Service and other revenues for 1994, with
and without business units sold, increased 3 percent and 4 percent,
respectively, over 1993. The increase in product revenues resulted primarily
from a large increase in unit shipments of the Company's lower-priced Himalaya
server products and increased revenues from networking products. The increase of
unit shipments of the Himalaya systems exceeded the effect of lower unit
pricing, a trend which increased throughout the year. The increase in service
and other revenues compared to 1993 is attributable primarily to a large
consulting project that occurred in the third quarter of 1994. Hardware service
revenues during 1994 remained relatively flat for the year despite the
increasing customer base during the year, as a result of improvement in hardware
reliability, which reduces both the demand for servicing and the related pricing
for such services.

  Total revenues for the fourth quarter of 1994 of $604 million increased 11
percent over the prior quarter and 15 percent over the fourth quarter of 1993,
excluding the effects of business units sold. Fourth quarter product revenues
increased 16 percent over the prior quarter and the fourth quarter of 1993,
excluding business units sold. Fourth quarter service revenues decreased 8
percent over the previ-
 
                                       12
<PAGE>   13
 
ous quarter and increased 10 percent over the fourth quarter of 1993, excluding
the effects of business units sold. Unit shipments for computer systems, based
on the number of processors shipped excluding single-processor workstations and
personal computers, increased 36 percent over the previous quarter and 47
percent over the fourth quarter of 1993. Fourth quarter trends for product
revenues magnify the impact that the lower-priced Himalaya system is having on
the Company's operations.

  Historically, the second half of the Company's fiscal year is stronger than
the first. This pattern was accentuated in 1994, as the Himalaya product line
received market acceptance. Management expects quarterly trends in 1995 to be
consistent with the Company's historical trends.

  Total revenues for 1993 decreased slightly from 1992 revenues, less than 1
percent. The Company believes the decrease was primarily attributable to
customer hesitation to purchase products in the third quarter of 1993 in
anticipation of the introduction of the Company's significantly lower-priced new
Himalaya server products, which were announced in the fourth quarter of 1993.

==============================================================
</TABLE>
 
Computer systems revenues increased 8 percent in 1994 compared to 1993,
excluding the effects of business units sold. The increase primarily resulted
from steadily increasing unit shipments of the new lower-priced Himalaya server
products, notwithstanding corresponding declines in per unit revenues. Excluding
services, Tandem's RISC (reduced instruction set computing) based products
comprised approximately 80 percent of 1994 computer systems revenues compared to
40 percent in 1993, replacing sales of CISC (complex instruction set computing)
based products. RISC products in 1994 consisted principally of the Himalaya
product line, while in 1993 the principal RISC product was the Cyclone/R system.
Unit shipments of all computer system lines increased 42 percent in 1994 over
1993, based on the number of processors shipped excluding workstations and
personal computers.

  Excluding the effects of business units sold, networking product revenues
increased 10 percent in 1994 compared to 1993, primarily as a result of higher
sales of OEM and third party products. On March 31, 1994, NetWorth, Inc.,
acquired approximately 1.6 million shares of its common stock then held by the
Company, thereby reducing the Company's ownership from approximately 51 percent
to approximately 32 percent. As a result, the Company's investment in NetWorth
is now accounted for under the equity method of accounting and not as a
consolidated subsidiary. Accordingly, NetWorth's revenues were not included in
consolidation beginning in the third quarter of 1994. NetWorth's revenues
represent approximately 3 percent, 7 percent, and 4 percent of the networking
revenues for 1994, 1993, and 1992, respectively, as displayed in the table
above.

Revenues in the United States in 1994 increased 4 percent, in the aggregate,
compared to 1993, but increased 10 percent, excluding the effects of business
units sold. The trends in the U.S. and the underlying causes are consistent with
the Company's performance on a consolidated basis, as described previously.
Excluding the effects of business units sold, revenues in Europe decreased 1
percent year over year, including negative effects of foreign exchange
fluctuations of approximately

3 percent. Revenues in the United Kingdom expanded by 30 percent in 1994,
excluding the effects of business units sold, approximately half of which was
due to the completion of the first phase of a contract with a new customer.
Similar growth in the United Kingdom in 1995 is not anticipated. The results in
the United Kingdom were offset by continued sluggish sales performance in
Germany and other parts of Europe, which experienced a 7 percent and 12 percent
decline from the prior year, respectively, excluding the effects of business
units sold. Management believes that European sales suffered from an overall
weak economic environment in Europe, hindering customers' investments in capital
equipment, particularly during the first six months of 1994. In Japan, revenues
increased 14 percent in 1994 compared to 1993 due in large part to exchange rate
changes (favorable impact of approximately 9 percent) and to increased product
shipments. Asia/Pacific revenues in 1994 increased by 37 percent due primarily
to increased product shipments, and to a lesser extent to exchange rate changes
(approximately 5 percent).
 

COST OF REVENUES

 
During 1994, product margins declined 4 points to 59 percent, excluding the
effects of business units sold. Computer system margins declined to 63 percent
in 1994, while networking margins declined to 44 percent. Computer system
margins declined principally as a result of the introduction of Himalaya server
products at the beginning of the year and a shift in product mix to include the
expanding Integrity product line, both of which have lower prices than previous
generations of Tandem systems. Networking margins declined primarily as a result
of shifts in product mix. Management expects the Company's product margins to
continue to decline in 1995, although at a lower rate than in 1994. Margins on
service and other revenues increased 3 points to 35 percent in 1994, excluding
the effects of business units sold, due primarily to lower service costs and
overhead associated with cumulative restructuring actions. Management expects
service margins to remain stable in 1995.

  Product margins in 1993 declined compared with 1992 primarily as a result of
changes in geographic, channel, and product mix and unit sales price reductions.
Margins on service and other revenues also declined in 1993 over 1992 primarily
due to higher than anticipated costs on certain projects in Tandem's system
integration business.

 
RESEARCH AND DEVELOPMENT EXPENSES

 
Research and development spending in 1994 decreased $44 million, or 14 percent,
over 1993 due primarily to restructuring actions taken since 1993. The
restructuring actions resulted in reduced headcount -- approximately 50 percent
of the spending reduction -- and higher levels of software capitalization as
certain projects reached technological feasibility -- approximately 27 percent
of the reduction. Approximately 23 percent of the decrease is a result of
business units sold.

  Research and development expenses in 1993 increased $28 million, or 10
percent, over 1992 due primarily to headcount additions, salary increases, and
higher contractor costs during the first three quarters of 1993 in support of
the Company's development efforts on the Himalaya and Integrity product lines.

  Management anticipates that research and development spending will increase in
1995 in dollars, but not as a percentage of revenues, as the Company prepares to
introduce the next generation of the Himalaya product line, continues to
increase functionality of the Integrity systems, and continues development of
open access to the Company's systems.

 
MARKETING, GENERAL, AND ADMINISTRATIVE EXPENSES

 
In 1994, marketing, general, and administrative expenses declined $120 million,
or 14 percent, compared to 1993, largely as the result of restructuring actions
initiated in the third quarter of 1993. Of these decreases, approximately 35
percent pertains to business units sold and 6 percent pertains to reduction in
goodwill amortization derived from the goodwill written off as part of the
restructure. The remaining impact from restructuring actions is in the form of
salary and related benefits reductions from both reduced headcount and salary
cuts in place for 1994 and reduced facility costs. In 1993, marketing, general,
and administrative expenses declined slightly over 1992 by $4 million, or 0.5
percent, primarily due to restructuring actions, somewhat offset by advertising
costs incurred late in 1993 to increase awareness of Tandem in the marketplace.
 
                                       14
<PAGE>   15
 
  Aggressive cost containment and restructuring actions have progressively
reduced the ongoing level of fixed expenses. Management expects such fixed
expenses to continue to decline somewhat in 1995, as the Company continues its
implementation of the 1993 restructuring plan. However, certain expenses, such
as commissions and incentive compensation for sales and marketing staff, vary as
revenues fluctuate.
 
RESTRUCTURING CHARGES
 
In 1993 and 1992, the Company recorded restructuring charges of $451 million and
$106 million, respectively, to reengineer the business, largely necessitated by
the migration toward open systems and servers based on RISC technology which
resulted in lower-priced, yet more powerful parallel servers. The restructuring
provisions, supported by appropriate levels of specificity for planned actions,
were established and approved by the Company's executive management and its
Board of Directors. The restructuring charges covered reduction of work force,
consolidation of facilities, disposal of assets no longer required, and the
write-off of cost in excess of net assets acquired (goodwill) as discussed
below. As of September 30, 1994, $144 million remains in accrued liabilities and
$29 million remains as a reduction of net property, plant, and equipment. At
September 30, 1993, $243 million remained in accrued liabilities and $40 million
remained as a reduction of net property, plant, and equipment.

  Included in the 1993 restructuring charge was a $151 million write-off of
goodwill associated with the 1988 acquisition of UB Networks, Inc. (formerly
Ungermann-Bass, Inc.). As of June 30, 1993, the Company's UB Networks subsidiary
reported its second consecutive quarter of substantial and increased losses from
operations. The results reflected an accelerating two-year decline in its
financial performance. Due to the disappointing financial results, the lack of
certain products in high-growth sectors of the market, and unsuccessful efforts
by the subsidiary's management to attract public or private investment partners,
management initiated a plan to restructure the operations which included
reducing headcount, consolidating facilities, and redirecting certain
development programs. Additionally, based upon the then current undiscounted
cash flow projections, it was concluded that the acquisition goodwill could no
longer be assured of recovery and the balance of $151 million was written off
and included in the 1993 restructuring charges.

  Information relating to restructuring activity, other than the goodwill
write-off discussed above, is presented below.

The provisions for reduction of work force include severance, related medical
and other benefits, and in the 1993 provision, retention incentives payable
during 1995 for a limited number of employees critical to the Company's ongoing
operations. The provisions include termination benefits for approximately 2,500
employees, of which approximately two-thirds were based in the United States.
Approximately one-half of the planned terminations were in sales, marketing, and
administrative functions, and the balance was evenly distributed among
manufacturing, service and support, development, and UB Networks. Approximately
650 employees were terminated during each of the 1992, 1993, and 1994 fiscal
years, and approximately 125 were terminated shortly after the Company's 1994
year-end. Together with retention incentives, payments for work force reduction
during the first quarter of 1995 are expected to be approximately $20 million. A
significant and unanticipated level of voluntary employee terminations during
1994 has complicated work force restructuring actions, and the Company believes
that the balance of reduction in work force costs will likely be incurred later
in 1995. Due to geographic and compensation mixes, average employee termination
payments are expected to exceed those for employees terminated from 1992 through
the first quarter of 1995.
 
                                       15
<PAGE>   16
 
  The provisions for facilities include lease payments and fixed costs on idle
facilities, write-offs of related facility improvements, moving and other
expenses associated with the closure of approximately 2 million square feet of
office and manufacturing space throughout all principal geographic areas, and
the write-down of properties no longer to be developed. As of September 30,
1994, facilities restructure reserves included approximately $42 million
representing lease payments and expenses for idle facilities, approximately $9
million representing related improvements, and approximately $3 million of
estimated future losses on properties not to be developed. The above leases have
remaining terms generally not exceeding five years.

  The provision for internal systems includes estimated costs to reengineer and
accelerate the implementation of new systems and processes required to support
significant consolidation, centralization, and reorganization in nearly every
business function and to facilitate the significant work force reductions
referred to above. These efforts are expected to be substantially completed
during 1995.

  The provision for discontinued activities in 1992 includes, principally, lease
and other costs and losses associated with closing a manufacturing operation in
Germany during 1992 and the sale of the Company's Watsonville, California,
printed circuit board manufacturing operation in early 1993. The 1993 provision
includes, principally, costs and losses associated with discontinuing two
product initiatives at the Company's telecommunications division and with
exiting and eventually selling certain assets and the disk drive business of the
Company's Array Technology subsidiary in 1994. The above provisions are net of
approximately $6 million and $10 million cash proceeds received in 1993 and
1994, respectively. As of September 30, 1994, estimated losses on assets not yet
disposed aggregated approximately $8 million. Future cash utilization consists
of approximately $2 million representing the present value of a long-term land
lease in Germany and approximately $1 million representing sustaining support
and other expenses through 1995 for discontinued products.

  The provisions for other costs consist principally of moving, travel,
temporary living, and other expenses in connection with reorganizing and
centralizing general and administrative functions of the Europe division and
with reorganizing and relocating headquarters' operations in Asia/Pacific and
Latin America; costs associated with the relaunch of a new corporate image at
the UB Networks subsidiary and asset write-offs as a result of redirecting
product strategies; temporary living, travel, and duplicate development
laboratory costs associated with an offshore software development organization
for certain development and support activities; relocation expenses and
equipment write-offs in connection with consolidating and moving manufacturing
activities to a new facility in Fremont, California, in mid-1995; and duplicate
costs and expenses associated with opening a new manufacturing facility in
Scotland during 1994. These actions are expected to be substantially completed
during 1995.
 
IMPACT OF CURRENCY AND INFLATION
 
The Company's international operations generally consist of sales and support
organizations that generate revenues and incur service costs and marketing,
general, and administrative expenses in local currencies. Product costs,
research and development, and corporate marketing and administrative expenses
are mostly incurred in U.S. dollars. Thus, a strengthening of local currencies
against the U.S. dollar has a positive influence on international revenues
translated into dollars and a negative effect on translated local costs and
expenses. A weakening of local currencies has a negative effect on translated
international revenues and a positive effect on translated local costs and
expenses. Tandem's hedging program moderates the impact of exchange rate changes
on profitability and cash flows.

  During 1994, currencies in Europe and Latin America generally weakened against
the U.S. dollar compared to the prior year periods, negatively affecting
revenues and positively affecting local costs and expenses. The overall effect
of exchange rates was negative on European results during 1994. The negative
impact on operating results from these countries, however, was more than offset
by the favorable impact resulting from the U.S. dollar weakening against the
Japanese yen and other Asia/Pacific currencies. The strengthening of the
Japanese yen and other Asia/Pacific currencies contributed positively to
revenues and to operating results in 1994. The resulting overall effect of
currency movements in 1994, though positive, had no material impact on operation
results for the year. In 1993, the strength of the U.S. dollar against
international currencies had a slightly negative influence on international
revenues and operating results. In 1992 the effect was modestly positive.
 
                                       16
<PAGE>   17
 
  The effect of inflation on the Company's financial position has not been
significant.
 
NET INCOME (LOSS) AND EARNINGS (LOSS) PER SHARE
 
In addition to the factors discussed above, 1994 net income of $170 million
includes a $23 million first quarter pre-tax nonoperating gain from the sales of
ACI and ACI, Ltd. The 1993 net loss of $518 million included a $12 million
positive adjustment representing the cumulative effect as of October 1, 1992, of
adopting Statement of Financial Accounting Standards No. 109 (SFAS No. 109),
"Accounting for Income Taxes," and a $451 million restructuring charge. The 1992
net loss of $41 million included $106 million in restructuring charges.
Excluding the restructuring charges, 1993 pre-tax loss was $12 million and 1992
pre-tax income was $74 million.

  The effective tax rate for 1994 was 6.1 percent, arising principally from
taxes currently payable in foreign jurisdictions. Tandem expects to continue to
report income in certain foreign jurisdictions, which will result in tax
provisions despite loss carryforwards which are available primarily to offset
U.S. and certain foreign income. Although the Company incurred a loss in 1993,
there was a provision for income taxes consisting primarily of taxes currently
payable in foreign jurisdictions and a $55 million increase in the valuation
allowance. The valuation allowance increased during the year because the Company
determined that deferred tax assets, established in prior periods, no longer met
the realizability criteria under SFAS No. 109. A significant portion of the 1993
and 1992 operating loss provided no current tax benefit.

  Weighted average shares outstanding increased from 1993 due to sales of stock
to employees under stock plans and to dilutive stock options, but these
increases were partially offset by a decrease relating to the planned
termination of Tandem's Employee Stock Ownership Plan (ESOP).
 
FINANCIAL CONDITION
 
During the year, cash and cash equivalents increased by $18 million, from $106
million to $124 million. The Company generated $116 million positive cash flow
from operations during 1994 compared to $135 million in 1993. Net cash used in
investing activities was $116 million during 1994, compared to $174 million,
excluding purchases of short-term investments, in 1993. Investing activities in
1994 included approximately $227 million of investment in property, equipment,
and software development, partially offset by $71 million received from the sale
of businesses and $41 million received from the sale of property, plant, and
equipment. Financing activities, consisting of sales of stock and net
borrowings, provided $15 million compared to $19 million in 1993.

  Accounts receivable days, excluding business units sold, increased to 77 days
at the end of 1994 from 74 days at the end of 1993. Inventory days, excluding
business units sold, decreased to 54 days at 1994 year-end versus 58 days at the
end of 1993.

  At September 30, 1994, total debt was $145 million compared with $155 million
at September 30, 1993, of which $122 million and $114 million, respectively,
represent limited recourse borrowings against lease receivables. Repayments on
the lease borrowings are sourced from the underlying lease receivables which are
collected directly by the lending institution and are scheduled as follows (in
millions): $54 (1995), $38 (1996), $21 (1997), $8 (1998), and $1 (thereafter).
Repayments on the remaining debt will be funded through operations and are as
follows (in millions): $4 (1995), $10 (1996), $5 (1997), $1 (1998), and $3
(thereafter). Total debt as a percentage of total capital decreased to 13
percent at September 30, 1994, from 17 percent at September 30, 1993.

  Cash used for restructuring actions aggregated $88 million, $48 million, and
$46 million for 1994, 1993, and 1992, respectively. Cash requirements for
restructure actions for 1995 are expected to be similar to 1994 and will be
funded by cash generated from operations.

  In December 1993, Tandem secured a three-year financing facility (Financing
Facility) to replace the multiple option financing facility, which the Company
canceled in the fourth quarter of 1993. Under the Financing Facility, the
Company can sell an interest in up to $150 million of qualified domestic
receivables on a limited recourse basis. One component of the Financing
Facility, which allows for sales of an interest in accounts receivable up to $75
million, expires in 1996, but is renewable annually with the consent of both
parties. A second component of the Financing Facility, which allows for sales of
an interest in accounts receivable up to $75 million, expires in 1997. The total
financing available under the Financing Facility is limited to a pool of
qualified domestic receivables. During 1994 the Company sold an interest in
receivables of $35 million, which was fully redeemed by September 30, 1994.
 
                                       17
<PAGE>   18
 
  In addition to the Financing Facility, other possible sources of working
capital include cash generated from operations and other financing arrangements.
Management believes that the financing sources available at September 30, 1994,
are adequate to meet Tandem's financing needs, both in the short and long term.

  During May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115 (SFAS No. 115), "Accounting for Certain
Investments in Debt and Equity Securities," which requires a change in the
method used to account for certain investments. The Company is required to adopt
SFAS No. 115 in 1995. The Company has evaluated the implications of SFAS No. 115
and does not expect it to have a material impact on the Company's financial
condition or results of operations.
 
OUTLOOK AND RISKS
 
OVERVIEW
 
During the year, Tandem continued to position itself to compete in an open
systems environment based on client/server computing. The Company recognizes
that the transition to lower-priced systems carries risk and that the volume of
shipments must continue to increase from historic levels in order to generate
the revenues to allow Tandem to sustain profitability, even with a lower overall
cost structure.

  Management expects the shift to lower-priced, lower-margin Himalaya servers
and a product mix shift to lower-margin UNIX systems and networking products to
continue during 1995, which will result in a continuing decline in product
margins. A key challenge in meeting the Company's 1995 operating plan includes
shipping sufficiently increased unit volumes of new lower-priced products to
achieve increased revenues, and concurrently controlling the cost structure of
the Company. Management is encouraged by the cost containment results since the
July 1993 restructuring actions, but key challenges remain.
 
CORE COMPUTER OPERATIONS
 
In general, it is difficult to forecast Tandem revenues. A significant portion
of 1995 revenue is expected to come from the Himalaya product line. Management
is encouraged by our 1994 results; revenues and earnings will be negatively
affected if there are unforeseen difficulties in continuing to migrate current
customers and to attract new customers to Himalaya systems.

  The Company has taken actions to reduce sales prices and improve product
performance, and anticipates continuing to price products aggressively. While
the Company expects these pricing actions to affect product margins negatively,
the decline will be partially offset by plans to accelerate the rate of
higher-performance new product introductions. Management's goal is to maintain a
competitive price/performance market position and to continue to realize the
positive growth in unit demand experienced in 1994.
 
UB NETWORKS, INC.
 
The market for networking products is expanding rapidly. The most significant
expansion has occurred in the low end of the market, while UB Networks has
historically competed in the higher end. To address the situation, UB Networks
has developed more competitive products, implemented a new pricing strategy, and
consolidated its manufacturing with Tandem. As part of the restructuring in
1993, UB Networks made certain key management changes, reduced staff, and began
consolidating facilities. These actions have led to renewed growth and improved
cost containment at UB Networks.

  UB Networks' success is dependent upon its ability to enhance its existing
products and to develop and introduce, on a timely and cost-effective basis, new
products that keep pace with technological developments and emerging industry
standards and that address increasingly sophisticated customer requirements.

  The Company is considering all of its options with respect to UB Networks,
including an initial public offering.
 
FOREIGN OPERATIONS
 
A significant portion of Tandem's revenues and operating contribution is derived
from operations in Europe and the Far East. Overall economic weakness in the
European community had a negative effect on revenues and operating results over
the last year. While Tandem engages in hedging activities to mitigate the effect
of exchange rate fluctuations, continued economic weaknesses in Europe are
expected in the near future. Economic conditions in Europe, particularly as they
relate to capital equipment spending, represent a risk to achieving Tandem's
1995 financial goals.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CONSOLIDATED FINANCIAL STATEMENTS
 
The consolidated financial statements include the accounts of Tandem Computers
Incorporated and its majority-owned subsidiaries (the Company) after the
elimination of intercompany accounts and transactions.
 
REVENUE RECOGNITION
 
The Company generally recognizes revenue from hardware and software product
sales at the time of shipment. When significant obligations remain after
products are delivered, revenue is recognized only after such obligations are
fulfilled. Product support and other revenues are recognized ratably over the
contractual period or as the services are provided.
 
TRANSLATION OF NON-U.S. CURRENCY AMOUNTS
 
The Company's non-U.S. subsidiaries use as their functional currency the local
currencies of the countries in which they operate. Their assets and liabilities
are translated into U.S. dollars at the exchange rates in effect at the balance
sheet date. Revenues and expenses are translated at average rates of exchange
prevailing during the period. In addition, all ongoing adjustments resulting
from the process of translating each subsidiary's financial statements into U.S.
dollars have been accumulated and recorded within a separate component of
stockholders' investment. Foreign currency transaction gains and losses are not
material and are included in the determination of net earnings.
 
INCOME TAXES
 
The Company accounts for research and development tax credits as a reduction of
the provision for income taxes in the year in which the credits are realized. In
general, the Company's practice is to provide U.S. federal taxes on
undistributed foreign earnings.

  Effective October 1, 1992, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income Taxes." See
the Income Taxes note to the Consolidated Financial Statements.
 
EARNINGS (LOSS) PER SHARE
 
Earnings per share is based on the weighted average number of common and common
equivalent shares outstanding. Common equivalent shares result from the assumed
exercise of outstanding stock options which have a dilutive effect when applying
the treasury stock method. Loss per share is calculated using the weighted
average number of common shares outstanding during the period. Fully diluted
earnings per share are substantially the same as reported earnings per share. As
a result of terminating the Employee Stock Ownership Plan (ESOP), the
approximately 2.4 million unallocated common shares held by the ESOP trust,
which will be returned to Tandem's treasury, have been excluded from the 1994
weighted average common shares and shares outstanding calculations. Common and
common equivalent shares were as follows:

============================================================
</TABLE>
 
CASH AND EQUIVALENTS
 
Cash equivalents are valued at cost, which approximates market value; have
original maturity dates not exceeding 90 days; and generally consist of
certificates of deposit, time deposits, treasury notes, money market preferred
stocks, municipal notes, and commercial paper.
 
SHORT-TERM INVESTMENTS
 
Short-term investments consist of U.S., state, and local debt securities, and
are stated at amortized cost, which approximates market value.
 
INVENTORIES
 
Inventories are stated at the lower of cost (first-in, first-out) or market. The
components of inventories at September 30 were as follows:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
PROPERTY, PLANT, AND EQUIPMENT
 
Property, plant, and equipment are stated at cost. Depreciation and amortization
are computed using the straight-line method over estimated useful lives.
 
COST IN EXCESS OF NET ASSETS ACQUIRED
 
The excess acquisition cost over the fair value of net assets of businesses
acquired is being amortized using the straight-line method over estimated lives
ranging from 5 to 10 years as of September 30, 1994. Amortization expense for
1994, 1993, and 1992 was $3.9 million, $14.9 million, and $17.0 million,
respectively. During 1993, $151 million of unamortized cost in excess of net
assets acquired was written off. See the Restructuring note to the Consolidated
Financial Statements.
 
SOFTWARE DEVELOPMENT COSTS
 
The Company capitalizes software development costs when the resulting products
become "technologically feasible" and amortizes those costs when, and as, the
products are shipped. The annual amortization of the capitalized amounts is the
greater of the amount computed based on the estimated revenue distribution over
the products' remaining life or a straight-line method, generally three years,
from the date of product release. The amounts of unamortized software
development costs included in other assets at September 30, 1994 and 1993, were
$117.7 million and $100.4 million, respectively. The amortization expense for
1994, 1993, and 1992 was $36.0 million, $33.1 million, and $30.4 million,
respectively.
 
ADVERTISING EXPENSES
 
The Company accounts for advertising costs as expense in the period in which
they are incurred. Advertising expense for 1994, 1993, and 1992 was $28.5
million, $32.3 million, and $16.2 million, respectively.
 
FINANCIAL INSTRUMENTS
 
OFF BALANCE SHEET RISK
 
The Company enters into foreign currency forward exchange and option contracts
to reduce the impact of currency fluctuations on intercompany and other foreign
currency denominated balance sheet positions, and on certain anticipated
intercompany revenue transactions related to sales by its foreign subsidiaries
which are expected to occur within 12 months. The objective of these contracts
is to neutralize the impact of foreign currency exchange rate movements on the
Company's operating results. The gains and losses on forward exchange contracts
and option contracts are included in earnings when the underlying foreign
currency denominated transaction is recognized. Costs associated with entering
forward and option contracts are amortized over the life of the instruments. The
cash flows related to gains and losses on these contracts are classified as
operating activities in the Consolidated Statements of Cash Flows.

  The foreign currency forward exchange contracts described above generally
require the Company to sell foreign currencies for U.S. dollars at rates agreed
to at the inception of the contracts. Foreign currency option contracts
generally provide the Company with the right, but not the obligation, to sell a
specified amount of foreign currency at a fixed price on a specified future
date. The forward contracts generally have maturities that do not exceed three
months. The option contracts generally have maturities that range from 6 to 12
months. These contracts do not subject the Company to significant market risk
from exchange rate movements because the contracts offset gains and losses on
the balances and transactions being hedged. At September 30, 1994, the Company
had $142 million of foreign exchange forward contracts outstanding and $65
million of option contracts outstanding in 16 different currencies. At September
30, 1993, the Company had $282 million of foreign exchange forward contracts
outstanding and $62 million of option contracts outstanding in 16 different
currencies. Contracts to exchange European currencies and the Japanese yen
represent approximately 94 percent of the total in 1994 and 95 percent of the
total in 1993. Unrealized gains and losses related to these instruments at
September 30, 1994 and 1993, are not material. The Company does not anticipate
any material adverse effect on its financial position resulting from the use of
these instruments.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
For certain of the Company's financial instruments, including cash and
equivalents, accounts receivable and payable, notes payable, short-term
borrowings,

and accrued liabilities, the carrying amounts approximate fair value due to
their short maturities. The following table provides information regarding the
estimated fair values of other financial instruments at September 30, 1994:

==========================================================
</TABLE>
 
The fair values for long-term obligations have been estimated using a discounted
cash flow analysis based upon interest rates which approximate current interest
rates for similar borrowings. The fair value of the foreign exchange forward
contracts is based upon quoted market prices for the same or similar
instruments. The fair value of option contracts is estimated using option
pricing models. These values represent general approximations of potential value
and are not necessarily the values which will be ultimately realized.
 
  During May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115 (SFAS No. 115), "Accounting for Certain
Investments in Debt and Equity Securities," which requires a change in the
method used to account for certain investments. The Company is required to adopt
SFAS No. 115 in 1995. The Company has evaluated the implications of SFAS No. 115
and does not expect it to have a material impact on the Company's financial
condition or results of operations.
 
CONCENTRATIONS OF CREDIT RISK
 
Credit risk with respect to trade receivables is generally diversified due to
the number of entities that make up the Company's customer base and their
dispersion across many different industries and geographies. Credit risk is also
limited by the Company's credit evaluation process and reasonably short
collection terms. Bad debt expenses have been insignificant, and generally, the
Company does not require collateral or other security to support accounts
receivable. The Company has short-term cash and foreign exposure management
policies that limit the amount of credit exposure to any one financial
institution and restrict placement of the investments and contracts to financial
institutions evaluated as highly creditworthy.
 
RESTRUCTURING
 
During 1992, the Company developed a restructuring program aimed principally at
reducing its cost structure and improving employee productivity on a worldwide
basis. The restructuring actions resulted in a $106 million charge during 1992.
 
  During 1993, the Company initiated a separate restructuring program designed
to streamline operations and lower its worldwide cost structure in anticipation
of shipping the Himalaya product line. These restructuring actions resulted in a
charge of $451 million and included reduction of headcount, consolidation of
facilities, disposal of assets no longer required, and the write-off of cost in
excess of net assets acquired (goodwill) as discussed below. As of September 30,
1994, $144 million remains in accrued liabilities and $29 million remains as a
reduction of net property, plant, and equipment. At September 30, 1993, $243
million remained in accrued liabilities and $40 million remained as a reduction
of net property, plant, and equipment.
 
  As of June 30, 1993, the Company's UB Networks, Inc., subsidiary (formerly
Ungermann-Bass, Inc.) reported its second consecutive quarter of substantial and
increased losses from operations. The results reflected a continuing and
accelerating two-year decline in its financial performance. Due to the
disappointing financial results, the lack of certain products in high-growth
sectors of the market, and unsuccessful efforts by the subsidiary's management
to attract public or private investment partners, management initiated a plan to
restructure the operations which included reducing headcount, consolidating
facilities, and redirecting certain development programs. Additionally, based
upon the then current financial projections, which were significantly lower than
at acquisition, it was concluded the acquisition goodwill could no longer be
assured of recovery and the balance of $151 million was written off and included
in the 1993 restructuring charges.
 
                                       25
<PAGE>   26
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
  The goodwill write-off was calculated by comparing the balance with future
undiscounted cash flow projections at the subsidiary. The cash flow projections
anticipated the cost and probable future savings from the restructuring actions
as well as the benefits from products and technologies that were in the latter
stages of development. The projections indicated that undiscounted cash flows
from operations were expected to be negative for the next several years and
cumulatively negative for the remaining life of the goodwill.
 
  The restructuring provisions, supported by appropriate levels of specificity
for planned actions, were established and approved by the Company's executive
management and its Board of Directors. Actual restructuring costs are recognized
as reductions in related restructuring reserves in the period incurred.
Information relating to restructuring activity, other than the goodwill
write-off discussed above, is presented below.

The provisions for reduction of work force include severance, related medical
and other benefits, and in the 1993 provision, retention incentives payable
during 1995 for a limited number of employees critical to the Company's ongoing
operations. The provisions include termination benefits for approximately 2,500
employees, of which approximately two-thirds were based in the United States.
Approximately one-half of the planned terminations were in sales, marketing, and
administrative functions, and the balance was evenly distributed among
manufacturing, service and support, development, and UB Networks. Approximately
650 employees were terminated during each of the 1992, 1993, and 1994 fiscal
years, and approximately 125 were terminated shortly after the Company's 1994
year-end. Together with retention incentives, payments for work force reduction
during the first quarter of 1995 are expected to be approximately $20 million. A
significant and unanticipated level of voluntary employee terminations during
1994 has complicated work force restructuring actions, and the Company believes
that the balance of reduction in work force costs will likely be incurred later
in 1995. Due to geographic and compensation mixes, average employee termination
payments are expected to exceed those for employees terminated from 1992 through
the first quarter of 1995.
 
  The provisions for facilities include lease payments and fixed costs on idle
facilities, write-offs of related facility improvements, moving and other
expenses associated with the closure of approximately 2 million square feet of
office and manufacturing space throughout all principal geographic areas, and
the write-down of properties no longer to be developed. As of September 30,
1994, facilities restructure reserves included approximately $42 million
representing lease payments and expenses for idle facilities, approximately $9
million representing related improvements, and approximately $3 million of
estimated future losses on properties not to be developed. The above leases have
remaining terms generally not exceeding five years.
 
  The provision for internal systems includes estimated costs to reengineer and
accelerate the implementation of new systems and processes required to support
significant consolidation, centralization, and reorganization in nearly every
business function and to facilitate the significant work force reductions
referred to above. These efforts are expected to be substantially completed
during 1995.
 
  The provision for discontinued activities in 1992 includes, principally, lease
and other costs and losses associated with closing a manufacturing operation in
Germany during 1992 and the sale of the

Company's Watsonville, California, printed circuit board manufacturing operation
in early 1993. The 1993 provision includes, principally, costs and losses
associated with discontinuing two product initiatives at the Company's
telecommunications division and with exiting and eventually selling certain
assets and the disk drive business of the Company's Array Technology subsidiary
in 1994. The above provisions are net of approximately $6 million and $10
million cash proceeds received in 1993 and 1994, respectively. As of September
30, 1994, estimated losses on assets not yet disposed aggregated approximately
$8 million. Future cash utilization consists of approximately $2 million
representing the present value of a long-term land lease in Germany and
approximately $1 million representing sustaining support and other expenses
through 1995 for discontinued products.
 
  The provisions for other costs consist principally of moving, travel,
temporary living, and other expenses in connection with reorganizing and
centralizing general and administrative functions of the Europe division and
with reorganizing and relocating headquarters' operations in Asia/Pacific and
Latin America; costs associated with the relaunch of a new corporate image at
the UB Networks subsidiary and asset write-offs as a result of redirecting
product strategies; temporary living, travel, and duplicate development
laboratory costs associated with an offshore software development organization
for certain development and support activities; relocation expenses and
equipment write-offs in connection with consolidating and moving manufacturing
activities to a new facility in Fremont, California, in mid-1995; and duplicate
costs and expenses associated with opening a new manufacturing facility in
Scotland during 1994. These actions are expected to be substantially completed
during 1995.
 
ACCOUNTS RECEIVABLE
 
In December 1993, the Company entered into a three-year receivables purchase
agreement with a group of financial institutions whereby the Company can sell a
percentage ownership interest in an eligible pool of accounts receivable, up to
$150 million, on a limited recourse basis. Under the terms of the agreement,
the Company retains collection and servicing responsibilities for the
receivables and retains substantially the same risk of credit loss as if the
interest in receivables had not been sold. One component of the agreement for
up to $75 million will expire in 1997, and the other component for up to $75
million will expire in 1996 but is renewable annually with the consent of both 
parties.
 
During 1994 the Company sold an interest in receivables of $35 million, which
was fully redeemed by September 30, 1994.
 
PROPERTY, PLANT, AND EQUIPMENT
 
Property, plant, and equipment balances at September 30 were as follows:

Included in land and buildings at September 30, 1994 and 1993, were
approximately $55.9 million and $69.5 million, respectively, of costs relating
to land and land improvements on undeveloped parcels located near the Company's
Cupertino, California, headquarters.
 
  Depreciation expense was $122.6 million, $122.3 million, and $130.5 million in
1994, 1993, and 1992, respectively.
 
  The Company leases certain equipment, automobiles, and some of its operating
facilities and offices under operating lease agreements. Future minimum lease
payments as of September 30, 1994, net of amounts included in restructuring, are
as follows (in millions): $52.8 (1995), $47.4 (1996), $30.3 (1997), $21.9
(1998), $14.6 (1999), and $81.1 (2000 and thereafter). Rent expense was $62.7
million, $79.8 million, and $96.0 million in 1994, 1993, and 1992, respectively.
 
BUSINESS COMBINATIONS
 
In 1994 the Company sold 100 percent of its interest in Applied Communications,
Inc. (ACI), acquired April 12, 1991, and Applied Communications, Inc.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Limited (ACI, Ltd.), acquired December 31, 1991, for approximately $53.6 million
net cash. The sales of these subsidiaries resulted in a gain for financial
accounting purposes of $23 million. The consolidated results of operations
include the results of ACI and ACI, Ltd., from their respective acquisition
dates through December 31, 1993, their disposition date.
 
  Effective November 15, 1991, the Company acquired a 55 percent interest (50.1
percent on a fully diluted basis) in NetWorth, Inc. (NetWorth). NetWorth
develops and sells hardware used in local area network systems. In 1993,
NetWorth completed an initial public offering of its common stock in which it
received net proceeds of $27 million. The Company participated in the offering
by purchasing new shares approximately in proportion to its then ownership. On
March 31, 1994, NetWorth acquired approximately 30 percent of the shares then
held by the Company for a cash purchase price of $20 million, financed by debt,
thereby reducing the Company's ownership to approximately 32 percent. After
expenses of the transaction and adjusting the Company's investment to reflect
its approximate $5.6 million equity in NetWorth's remaining net assets, the
Company realized no gain or loss for financial accounting purposes. From March
31, 1994, the investment in NetWorth is accounted for under the equity method of
accounting and is included in other assets.
 
  On March 15, 1994, the Company sold its interest in the storage subsystems
business of Array Technology Corporation, acquired in 1990, together with
certain assets, to EMC Corporation for approximately $10 million cash. As part
of its 1993 restructuring plan and related provision, the Company decided to
sell or otherwise dispose of this business unit. Accordingly, the transaction
was recorded as part of restructuring activity and no gain or loss was realized
for financial accounting purposes.
 
  In 1993, the Company sold 100 percent of its interest in MPACT EDI Systems,
Inc. (MPACT), acquired October 1, 1991, to Immedia Infomatic Corporation
(Immedia), a Canadian company. In exchange, the Company received cash and
approximately 20 percent interest in the outstanding common stock of Immedia.
The sale did not result in a gain or loss for financial accounting purposes. The
consolidated results of operations include the results of MPACT through June 30,
1993, its disposition date.
 
LEASING PROGRAM
 
The Company offers lease financing of selected products to its customers.
Sales-type leases are originated by the Company and either sold on a nonrecourse
basis or used as collateral for borrowings from certain third-party financial
institutions. Under lease borrowings, the Company receives all proceeds at the
inception of the lease in the form of a limited recourse borrowing. The
third-party financial institution assumes the administrative responsibility for
collection of the lease receivables and the credit risk, subject to the limited
recourse provisions. In the event of a default by a lessee, recourse by the
financial institutions is limited to the collateralized computer equipment and a
recourse amount, if any, from a limited recourse pool established as a
percentage of each associated group of financed lease transactions. The Company
may also be required to participate in remarketing the computer equipment on a
"best efforts" basis on behalf of the financial institutions.
 
  The following table relates the borrowing and repayment activity in the
lease-related installment notes to the investment in sales leases:

  At September 30, 1994 and 1993, reserves for recourse liabilities on lease
receivables were approximately $5.5 million and $7.2 million, respectively.
 
SHORT-TERM BORROWINGS
 
Short-term borrowings consisted of notes payable of $15.1 million at September
30, 1993.
 
  Notes payable generally consist of notes, bankers' acceptances, and borrowings
under uncommitted credit lines at a weighted average interest rate of 3.7
percent at September 30, 1993. The carrying value of short-term borrowings
approximated fair values due to their short-term nature.
 
  In 1993, the Company suspended its $200 million commercial paper program.
Borrowings under the commercial paper program were insignificant during 1993.
 
LONG-TERM OBLIGATIONS
 
Long-term obligations at September 30 consisted of the following:

(3) Payable monthly; maturing 1997 to 2001; weighted average interest rates were
    11.4% and 11.6% at September 30, 1994 and 1993. The mortgages are secured by
    certain land and buildings, with a carrying value of approximately $45
    million.
 
Principal repayments required in the future are as follows (in millions): $58.1
(1995), $47.7 (1996), $26.0 (1997), $8.8 (1998), $2.4 (1999), and $1.6
(thereafter).
 
  At September 30, 1994 and 1993, the fair values of the long-term obligations
were $13.2 million and $12.8 million, respectively, for Japanese yen notes; and
$9.9 million and $13.2 million, respectively, for mortgages. Fair values have
been estimated using a discounted cash flow analysis based upon interest rates
which approximate current interest rates for similar borrowings.
 
  During 1993, the Company canceled its $200 million multiple option financing
facility (MOFF). The MOFF was scheduled to expire in September 1993. There had
never been borrowings under the MOFF. See the Accounts Receivable note to the
Consolidated Financial Statements regarding a new financing facility.
 
  The Company has guaranteed payment of personal bank loans made to officers
and other employees totaling $4.1 million and $4.2 million, at September 30,
1994 and 1993, respectively, under a bank credit line of $5.0 million.

INCOME TAXES
 
Effective October 1, 1992, the Company adopted Statement of Financial Accounting
Standards No. 109 (SFAS No. 109), "Accounting for Income Taxes." As permitted by
SFAS No. 109, the Company elected not to restate its financial statements for
any periods prior to October 1, 1992.
 
  Although the Company incurred a loss in 1993, there was a provision for income
taxes consisting primarily of taxes currently payable in foreign jurisdictions
and the reduction of deferred tax assets. A significant portion of the 1993
operating loss provided no current tax benefit.

For financial reporting purposes, the valuation allowance at September 30, 1994
and 1993, reduced net deferred tax assets to an amount realizable based upon
taxes paid for prior years without relying on future income. This amount
includes $24.5 million and $22.5 million in 1994 and 1993, respectively,
attributable to stock option deductions, the benefit of which will be credited
to paid-in capital when realized.
 
  The sources of deferred (prepaid) income taxes for the year ended September
30, 1992, were as follows:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
CAPITAL STOCK
 
The Company's authorized capital stock consists of 2.4 million shares of
preferred stock, of which .8 million shares are designated as Series A
Participating Preferred Stock; 4.0 million shares of Junior Common Stock; and
396.0 million shares of Common Stock. No shares of preferred stock or Junior
Common Stock have been issued. At September 30, 1994 and 1993, 21.1 million
shares and 24.0 million shares of Common Stock, respectively, were reserved for
future issuance under stock option plans and the employee stock purchase plan.
 
TREASURY STOCK
 
Treasury shares are carried at cost and are being used to satisfy requirements
under employee stock and benefit plans. At September 30, 1994 and 1993, the
Company held .7 million shares with an aggregate cost of $9.1 million and $8.9
million, respectively.
 
STOCK RIGHTS
 
The Company has a stock rights plan (the Plan), which is intended to protect
stockholders from unfair takeover practices. Under the Plan, each share of
Common Stock carries one right to obtain additional stock or other property with
equivalent value on terms provided in the Plan. The rights will not be
exercisable or transferable apart from the Common Stock until another person or
group of persons (subject to certain exceptions) acquires at least 20 percent of
the Common Stock or commences, or announces its intention to commence, a tender
offer for at least 30 percent of the Common Stock.
 
  The rights are redeemable by the Board of Directors or upon vote of the
stockholders for $.05 per right or property with an equivalent value, and expire
on June 17, 1998.
 
EMPLOYEE BENEFITS
 
The Company has a long-standing policy of encouraging all employees to become
stockholders. This policy is based on a belief that all stockholders benefit
from the higher productivity, lower turnover, and improved customer satisfaction
realized by providing employees with a personal stake in the Company's success.
 
EMPLOYEE STOCK OWNERSHIP PLAN
 
In 1989, the Company adopted the Tandem Computers Incorporated Employee Stock
Ownership Plan (ESOP). During 1993, contributions to the ESOP were suspended and
the Company announced its intention to terminate the ESOP and reacquire all of
the unallocated shares from the ESOP trust. Total compensation expense from all
contributions to the ESOP was $4.3 million and $6.7 million in 1993 and 1992,
respectively. Included in the ESOP compensation expense was the contribution of
279,000 shares and 440,000 shares of treasury stock in 1993 and 1992,
respectively. All allocated shares in the ESOP were automatically vested to the
participants on September 30, 1993.
 
  As of September 30, 1994 and 1993, there were approximately 2.4 million
unallocated outstanding shares in the ESOP trust that will be returned to
Tandem's treasury. For financial accounting purposes, the reacquisition and
termination of the ESOP will not require an outlay of cash, nor will it impact
the Company's results of operations.
 
STOCK OPTION PLANS
 
The Company has stock option plans under which eligible individuals may be
granted options to purchase shares of Common Stock, generally at fair market
value at the time of the grant. In general, options become exercisable six
months after the effective date, vest over four years, and expire no more than
ten years after the effective date. At the discretion of the Board of Directors,
options granted under the stock option plans may qualify as incentive stock
options under the Internal Revenue Code of 1986.
 
  In 1993, options were granted to acquire 2.6 million shares which generally
vest upon obtaining certain performance targets. If these targets are not met,
these options will become fully vested after four years. In 1994, 1.1 million of
these shares became fully vested.
 
  At September 30, 1994 and 1993, options for 2.3 million shares and 1.9 million
shares, respectively, were available for future grant.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
EMPLOYEE STOCK PURCHASE PLAN
 
Under the employee stock purchase plan, the Company may offer shares to
employees in two ways. Under the first method, eligible employees may elect to
purchase shares of Common Stock at the lower of 85 percent of fair market value
as of the last trading day before the beginning of each quarter, or as of the
last trading day of each quarter. Under this method, in 1994, 1993, and 1992,
employees purchased 1,111,000 shares for aggregate proceeds of $10.4 million;
1,351,000 shares for aggregate proceeds of $13.6 million; and 1,545,000 shares
for aggregate proceeds of $15.6 million, respectively. Under the second method,
the Company may grant to all eligible employees an option to purchase an
identical number of shares of Common Stock at not less than 85 percent of fair
market value at the grant date. As of September 30, 1994 and 1993, the Company
has reserved 2.1 million shares and 2.7 million shares, respectively, for future
issuance under its employee stock purchase plan.

Included in the 1993 activity are the cancellation of options for 3.7 million

affect the vested status of the shares.
 
  Although stock options may be exercised before they are fully vested and the
effect of all dilutive stock options is considered in the determination of
earnings per share, the following tables show the maximum number of shares that

OPTION LOAN PROGRAM
 
The Company has the Tandem Computers Incorporated Option Loan Program (the
Program) to enable employees to exercise certain outstanding options. Under the
Program, the Company can issue full recourse loans that are secured by a pledge
of the Company's Common Stock. Loan agreements entered into between the Company
and participants provide that in the event of a change in control of the Company
(as defined), principal and interest will be forgiven over a four-year period.
The amounts outstanding at September 30, 1994 and 1993, were insignificant.
 
401(K) INVESTMENT PLAN
 
The Company has a 401(k) investment plan (the Investment Plan) covering
substantially all of its U.S. employees. Under the Investment Plan,
participating employees may defer up to 18 percent of their pre-tax earnings,
subject to the Internal Revenue Service annual contribution limit ($9,240 for
calendar year 1994). The Company matches 63 percent to 100 percent of each
employee's contribution up to a maximum 2.5 percent of the employee's earnings.
The Company's matching contributions to the Investment Plan for 1994, 1993, and
1992 were $7.9 million, $7.3 million, and $2.8 million, respectively.
 
COMMITMENTS AND CONTINGENCIES
 
The Company is subject to legal proceedings and claims that arise in the normal
course of its business. In the opinion of management, these proceedings will not
have a material adverse effect on the financial position or overall trends in
the results of operations of the Company.
 
  See the Property, Plant, and Equipment note to the Consolidated Financial
Statements for a discussion of the Company's operating lease commitments.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of Tandem Computers Incorporated:
 
        We have audited the accompanying consolidated balance sheets of Tandem
Computers Incorporated and subsidiaries as of September 30, 1994 and 1993, and
the related consolidated statements of operations, stockholders' investment,
and cash flows for each of the three years in the period ended September 30,
1994. Our audits also included the financial statement schedules listed in the
Index at Item 14(a). These financial statements and schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedules 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 Tandem
Computers Incorporated and subsidiaries at September 30, 1994 and 1993, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended September 30, 1994, in conformity with
generally accepted accounting principles. Also, in our opinion, the related
financial statement schedules, when considered in relation to the basic
financial statements taken as a whole, present fairly in all material respects
the information set forth therein. 

        As discussed in the Notes to the Consolidated Financial Statements, in
1993 the Company changed its method of accounting for income taxes.
 
                                                              ERNST & YOUNG LLP

to engage in any lawful act or activity for which corporations may be organized

                                   ARTICLE IV

         The total number of shares of stock which the corporation shall have
the authority to issue is four hundred two million four hundred thousand
(402,400,000) shares, of which two million four hundred thousand (2,400,000)
shares of the par value of ten hundredths dollar ($.10) each, amounting in the
aggregate to two hundred forty thousand dollars ($240,000), shall be preferred
stock and four hundred million (400,000,000) shares of the par value of
twenty-five thousandths dollar ($.025) each, amounting in the aggregate to ten
million dollars ($10,000,000), shall be common stock.

         The preferred stock may be issued from time to time in one or more
series.  The Board of Directors is hereby expressly vested with authority to
fix by resolution or resolutions the designations and the powers, preferences
and relative, participating, optional or other special rights, and the
qualifications, limitations or restrictions thereof (including, without
limitation, the voting powers, if any, the dividend rate, conversion rights,
redemption price or liquidation preference of any series of preferred stock),
to fix the number of shares constituting any such series, and to increase or
decrease the number of shares of any such series (but not below the number of
shares thereof then outstanding).  In case the number of shares of any such
series shall be so decreased, the shares constituting such decrease shall
resume the status which they had prior to the adoption of the resolution or
resolutions originally fixing the number of shares of such series.

         Three hundred ninety-six million (396,000,000) shares of common stock
authorized hereinabove are designated "Common Stock" and four million
(4,000,000) shares of the Common Stock authorized hereinabove are designated
"Junior Common Stock," such Junior Common Stock to be issuable from time to
time in one or more series.  The Board of Directors is hereby expressly vested
with authority to fix by resolution or resolutions the designations and the
powers, preferences and relative, participating, optional or other special
rights, and the qualifications, limitations or restrictions (including without
limitation, the voting powers, if any, the dividend rate, conversion rights,
redemption price or liquidation preference) of any series of Junior Common
Stock, to fix the number of shares constituting any such series of Junior
Common Stock (but not below the number of shares thereof then outstanding).  In
case the number of shares of any such series of Junior Common Stock shall be so
decreased, the shares constituting such decrease shall resume that status which





                                      -2-
<PAGE>   3
they had prior to the adoption of the resolution or resolutions originally
fixing the number of shares of such series.

         The number of authorized shares of any class or classes of stock may
be increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the stock
of the Company entitled to vote in the election of directors.

         Designation of Series A Participating Preferred Stock

                 Pursuant to a resolution adopted on May 7, 1985, the Board of
         Directors created the Series A Participating Preferred Stock of the
         Corporation:

                 RESOLVED, that pursuant to the authority vested in the Board
         of Directors of this Corporation in accordance with the provisions of
         its Restated Certificate of Incorporation, a series of Preferred Stock
         of the Corporation be and it hereby is created, and that the
         designation and amount thereof and the voting powers, preferences and
         relative, participating, optional and other special rights of the
         shares of such series, and the qualifications, limitations or
         restrictions thereof are as follows:

         Section 1.  Designation and Amount.  The shares of such series shall
be designated as "Series A Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting such series shall
be 800,000.

         Section 2.  Dividends and Distributions.  The holders of shares of
Series A Preferred Stock shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
dividends payable on the dates on which a dividend or distribution on the
Common Stock, par value $.025 per share ("Common Stock," which term includes
Common Stock as constituted on any future date) of the Corporation is payable
(other than a dividend payable in Common Stock) (each such date being referred
to herein as a "Dividend Payment Date"), commencing on the first Dividend 
Payment Date after the first issuance of a share or fraction of a share of 
Series A Preferred Stock in an amount per share (rounded to the nearest cent), 
subject to the provision for adjustment hereinafter set forth, equal to 100 
times the aggregate per share amount of all cash dividends and 100 times the 
aggregate per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock of the
Corporation or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock since the
immediately preceding Dividend Payment Date or, with respect to the first
Dividend Payment Date, since the first issuance of any share or fraction of
a share of Series A Preferred Stock.  In the event the Corporation shall at any
time after May 31, 1985, declare or pay any dividend on Common Stock





                                      -3-
<PAGE>   4
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise) into a greater or lesser number of shares of Common Stock, whether
or not any Series A Preferred Stock is then outstanding, in each such case the
amount of dividend per share to which holders of shares of Series A Preferred
Stock are entitled immediately prior to such event shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in this Section immediately after it declares a
dividend or distribution on the Common Stock (other than a dividend payable in
shares of Common Stock).

         Dividends shall begin to be payable and to accrue on outstanding
shares of Series A Preferred Stock from the first Dividend Payment Date
succeeding the date of issue of such shares of Series A Preferred Stock, unless
the date of issue of such shares is prior to the record date for such Dividend
Payment Date, in which case dividends on such shares shall begin to be payable
and to accrue from the date of issue of such shares, or unless the date of
issue is a Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a dividend and before such Dividend Payment Date, in either of which
events such dividends shall begin to be payable and to accrue from such
Dividend Payment Date.  Accrued but unpaid dividends shall not bear interest.
Dividends paid on the shares of Series A Preferred Stock in an amount less than
the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.  The Board of Directors may fix a record date
for the determination of holders of shares of Series A Preferred Stock entitled
to receive payment of a dividend or distribution declared thereon, which record
date shall be no more than 60 days prior to the date fixed for the payment
thereof.

         Section 3.  Voting Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                 A.       Subject to the provision for adjustment hereinafter
         set forth, each share of Series A Preferred Stock shall entitle the
         holder thereof to 100 votes on all matters submitted to a vote of the
         stockholders of the Corporation.  In the event the Corporation shall
         at any time after May 31, 1985, declare or pay any dividend on Common
         Stock payable in shares of Common Stock, or effect a subdivision or
         combination or consolidation





                                      -4-
<PAGE>   5
         of the outstanding shares of Common Stock (by reclassification or
         otherwise) into a greater or lesser number of shares of Common Stock,
         then, whether or not any Series A Preferred Stock is then outstanding,
         in each such case the number of votes per share to which holders of
         shares of Series A Preferred Stock are entitled immediately prior to
         such event shall be adjusted by multiplying such number by a fraction
         the numerator of which is the number of shares of Common Stock
         outstanding immediately after such event and the denominator of which
         is the number of shares of Common Stock that are outstanding
         immediately prior to such event.

                 B.       Except as otherwise provided herein or by law, the
         holders of shares of Series A Preferred Stock and the holders of
         shares of Common Stock shall vote together as one class on all matters
         submitted to a vote of stockholders of the Corporation.

                 C.       Except as set forth herein, holders of Series A
         Preferred Stock shall have no special voting rights and their consent
         shall not be required (except to the extent they are entitled to vote
         with holders of Common Stock as set forth herein) for taking any
         corporate action.

         Section 4.  Certain Restrictions.

         A.      Whenever any cash dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the Corporation shall not

                 (i)   declare or pay dividends on, make any other
         distributions on, or redeem or purchase or otherwise acquire for
         consideration any shares of stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the
         Series A Preferred Stock, except for purchases pursuant to the terms
         of the Corporation's employee benefit plans;

                 (ii)  declare or pay dividends on or make any other
         distributions on any shares of stock ranking on a parity with the
         Series A Preferred Stock, except dividends paid ratably on the Series
         A Preferred Stock and all such parity stock on which dividends are
         payable or in arrears in proportion to the total amounts to which the
         holders of all such shares are then entitled;

                 (iii) redeem or purchase or otherwise acquire for
         consideration shares of any stock ranking on a parity

         with the Series A Preferred Stock, provided that the Corporation may
         at any time redeem, purchase or otherwise acquire shares of any such
         parity stock in exchange for shares of any stock of the Corporation
         ranking junior (either as to dividends or upon dissolution,
         liquidation or winding up) to the Series A Preferred Stock; or

                 (iv)  purchase or otherwise acquire for consideration any
         shares of Series A Preferred Stock, or any shares of stock ranking on
         a parity with the Series A Preferred Stock, except in accordance with
         a purchase offer made in writing or by publication (as determined by
         the Board of Directors) to all holders of Series A Preferred Stock and
         other such shares (if any) upon such terms as the Board of Directors,
         after consideration of the respective annual dividend rates and other
         relative rights and preferences of the respective series and classes,
         shall determine in good faith will result in fair and equitable
         treatment among the respective series or classes.

         B.      The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 5.  Reacquired Shares.  Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever 
shall be retired and canceled promptly after the acquisition thereof.  All such 
shares shall upon their cancellation become authorized but unissued shares of 
preferred stock and may be reissued as part of a new series of preferred stock 
to be created by resolution or resolutions of the Board of Directors, subject 
to the conditions and restrictions on issuance set forth herein.

         Section 6.  Liquidation, Dissolution or Winding Up.  Upon any
voluntary liquidation, dissolution or winding up of the Corporation, no 
distribution shall be made (1) to the holders of shares of stock ranking 
junior (either as to dividends or upon liquidation, dissolution or winding up)
to the Series A Preferred Stock unless, prior thereto, the holders of shares of 
Series A Preferred Stock shall have received $100.00 per share, plus an amount 
equal to accrued and unpaid dividends and distributions thereon, whether or
not declared, to the date of such payment, provided that the holders of shares 
of Series A Preferred Stock shall be entitled to receive an aggregate amount 
per share, subject to the provision for adjustment hereinafter set forth,
equal to 100 times the aggregate amount to be distributed per share to holders 
of Common Stock, or (2) to the holders of stock ranking on a parity (either as 
to dividends or upon liquidation, dissolution or winding up) with the Series A 
Preferred Stock,

except distributions made ratably on the Series A Preferred Stock and all other
such parity stock in proportion to the total amounts to which the holders of
all such shares are entitled upon such liquidation, dissolution or winding up.
In the event the Corporation shall at any time after May 31, 1985, declare or
pay any dividend on Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise) into a greater or lesser number of
shares of Common Stock, then, whether or not any Series A Preferred Stock is
then outstanding, in each such case the aggregate amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such
event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         Section 7.  Consolidation, Merger, etc.  In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which 
the shares of Common Stock are exchanged for or changed into other stock or 
securities, cash and/or any other property, then in any such case the shares of 
Series A Preferred Stock shall at the same time be similarly exchanged or 
changed in an amount per share, subject to the provision for adjustment 
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may 
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after May 31, 1985, declare or 
pay any dividend on Common Stock payable in shares of Common Stock, or effect 
a subdivision or combination or consolidation of the outstanding shares of
Common Stock (by reclassification or otherwise) into a greater or lesser number 
of shares of Common Stock, then, whether or not any Series A Preferred Stock 
is then outstanding, in each such case the amount set forth in the preceding 
sentence with respect to the exchange or change of shares of Series A Preferred 
Stock shall be adjusted by multiplying such amount by a fraction the numerator 
of which is the number of shares of Common Stock outstanding immediately after 
such event and the denominator of which is the number of shares of Common Stock 
that were outstanding immediately prior to such event.

         Section 8.  No Redemption.  The shares of Series A Preferred Stock
shall not be redeemable.

         Section 9.  Ranking.  The Series A Preferred Stock shall rank junior
to all other series of the Corporation's preferred stock as to the payment of 
dividends and the distribution of assets.

         Section 10.  Amendment.  The Restated Certificate of Incorporation of
the Corporation shall not be amended in any manner which would materially alter
or change the powers, preferences or special rights of the Series A Preferred
Stock so as to affect them adversely without the affirmative vote of the
holders of two-thirds or more of the outstanding shares of Series A Preferred
Stock, voting together as a single class.

                                   ARTICLE V

         The number of directors which shall constitute the whole Board of
Directors of this corporation shall be not less than nine (9) nor more than
fifteen (15).  The Board of Directors of this corporation may, within the
limits specified by this Article V, increase or decrease the exact number of
directors from time to time by resolution adopted by the affirmative vote of a
majority of the entire Board of Directors.  The exact number of directors shall
be nine (9) until changed pursuant to this Article V.  No decrease in the
number of directors shall shorten the term of any incumbent director.

         The directors shall be divided into three classes:  Class I, Class II
and Class III.  The number of directors in each class shall be as nearly equal
in number as possible.  Directors of each class shall serve for a term ending
on the third annual meeting of stockholders following the annual meeting at
which such class was elected.  The foregoing notwithstanding, each director
shall serve until his successor shall have been duly elected and qualified,
unless he shall die, resign or be removed.

         At each annual election the directors chosen to succeed those whose
terms then expire shall be identified as being of the same class as the
directors they succeed.  If for any reason the number of directors in the
various classes shall not conform with the formula set forth in the preceding
paragraph, the Board of Directors may redesignate any director into a different
class in order that the balance of directors in such classes shall conform
thereto.

         At all elections of directors of this corporation, each holder of
Common Stock shall be entitled to as many votes as shall equal the number of
votes which, except for this provision as to cumulative voting, he would be
entitled to cast for the election of directors with respect to his shares of
Common Stock, multiplied by the number of directors to be elected, and he may
cast all of such votes for a single nominee for director or may distribute them
among the number to be voted for, or for any two or more of them as he may see
fit.

         In case of any increase in the number of directors, the additional
directors may be elected by the Board of Directors to hold office until the
next election of the class for which such directors have been chosen and until
their successors are elected and qualified.

                                   ARTICLE VI

         In furtherance and not in limitation of the powers conferred by law,
the Board of Directors is expressly authorized, by resolution passed by a
majority of the whole board, to make, amend, alter or repeal the by-laws of
this corporation.

                                  ARTICLE VII

         This corporation reserves the right to amend, alter, change or repeal
any provisions contained in this Certificate of Incorporation in any manner now
or hereafter prescribed by law, and all rights herein conferred upon the
stockholders are granted subject to this reservation; provided, however, that
the affirmative vote of the holders of at least 80% of the voting power of all
of the then outstanding shares of the capital stock of this corporation
entitled to vote generally in the election of directors, voting together as a
single class, shall be required to amend or repeal this Article VII or Article
XI hereof.

                                  ARTICLE VIII

         Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers
appointed for this corporation under the provisions of Section 279 of Title 8
of the Delaware Code, order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of this corporation, as the
case may be, to be summoned in such manner as the said court directs.  If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.

                                   ARTICLE IX

         This corporation is to have perpetual existence.

<PAGE>   10
                                   ARTICLE X

         Meetings of stockholders may be held outside the State of Delaware, if
the by-laws so provide.  The books of this corporation may be kept (subject to
any provisions of law) outside of the State of Delaware.  Elections of
directors need not be by ballot unless the by-laws of this corporation shall so
provide.

                                   ARTICLE XI

         A.      A director of the corporation shall not be liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director except for liability which, by express provision of the
General Corporation Law of Delaware as in effect from time to time (hereinafter
"Delaware Law"), cannot be eliminated.

         B.      (i)  The corporation shall, to the fullest extent permitted by
Delaware Law, indemnify any person (the "Indemnitee") who is or was involved in
any manner (including, without limitation, as a party or a witness) in any
threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative
(including, without limitation, any action, suit or proceeding brought by or in
the right of the corporation to procure a judgment in its favor) (a
"Proceeding"), by reason of the fact that Indemnitee is or was a director,
officer, employee, agent, fiduciary or other official of the corporation, or is
or was serving another entity or enterprise in such capacity at the request of
the corporation, against all expenses and liabilities actually and reasonably
incurred by Indemnitee in connection with such Proceeding.

                 (ii)  The right to indemnification conferred by this Article
XI shall be presumed to have been relied upon by Indemnitee and shall be
enforceable as a contract right.  The corporation may enter into contracts to
provide individual Indemnitees with specific rights of indemnification to the
fullest extent permitted by Delaware Law and may create trust funds, grant
security interests, obtain letters of credit or use other means to ensure the
payment of such amounts as may be necessary to effect the rights provided in
this Article XI or in any such contract.

                 (iii)  Upon making a request for indemnification, Indemnitee
shall be presumed to be entitled to indemnification under this Article XI and
the corporation shall have the burden of proof to overcome that presumption in
reaching any contrary determination.  Such indemnification shall include the
right to receive payment in advance of any expenses incurred by Indemnitee in
connection with any Proceeding, consistent with the provisions of Delaware Law.





                                      -10-
<PAGE>   11
         C.      Any repeal or modification of the foregoing provisions of this
Article XI shall not adversely affect any right or protection of any director
or any Indemnitee existing at the time of such repeal or modification.
