                                     PART I

ITEM 1.  BUSINESS

General

          Amdahl Corporation ("Amdahl" or the "Company"), organized in 1970,
provides large-scale, high-performance general-purpose computer systems as well
as software, storage and communications products.  The Company also provides
consulting and professional services.  Its principal computer systems are
architecturally compatible at specific software and hardware interface levels
with the basic functions of competing IBM computer systems.  The Company also
develops and markets certain products for the open systems marketplace.
Amdahl's customer base is diversified and includes large corporations, financial
institutions, public utilities, government agencies and universities with high-
volume data processing requirements.

          Since its first product shipment in June 1975, the Company has
continued to introduce new and more powerful computer systems.  In December 1991
Amdahl began initial shipments of its newest system, the 5995M series.  In 1993
Amdahl began delivery of higher performance models in this series.  Since 1982
Amdahl has also offered high-performance direct access storage devices (DASD)
and front-end communications processors (FEP) for use with large-scale computer
systems.  In the third quarter of 1992 the Company began shipments of its newest
line of DASD.

          In addition to its primary product line of large-scale computers and
storage systems, Amdahl offers software products, educational and professional
services, and hardware maintenance services.  As part of its software products,
the Company has developed and offers Huron, a comprehensive applications
development and production system, and UTS, a UNIX based operating system for
the mainframe environment.

          During the latter half of 1993 the Company organized itself along
lines of business consisting of its compatible processor, storage, maintenance
and professional services, Huron and open systems operations in order to enable
Amdahl to more effectively diversify its product offerings beyond those
associated primarily with its large-scale computer systems.  The Company intends
to enhance its professional and consulting services business and also expects to
enter into partnerships and alliances with other companies as a way of enhancing
its existing product offerings or developing new products and services.  For
example, in June 1993 Amdahl and Electronic Data Systems Corporation ("EDS")
formed a joint venture, Antares Alliance Group, in which Amdahl holds an 80
percent (80%) interest, for the purpose of continuing the development and
marketing of Huron as well as certain software products contributed by EDS.  The
Company has also entered into a series of marketing and development agreements
with Sun Microsystems Inc. ("Sun") pursuant to which the Company will
<PAGE>
 
offer certain Sun products through its open systems organization.  Until its
Huron, professional services and open systems offerings are more fully
developed, however, the large-scale compatible processor business, including its
related storage product and maintenance service components, will continue to be
the primary source of the Company's revenues.

          Fujitsu Limited ("Fujitsu"), a major Japanese manufacturer of computer
systems, telecommunications equipment and electronic components, owns
approximately 45.01% of the Company's outstanding common stock and is of
substantial importance to the Company in the areas of manufacturing and
technical assistance and supply of subsystems and components.  Fujitsu also
manufactures the Company's DASD and FEP products.  In November 1993 Amdahl and
Fujitsu entered into a preliminary agreement pursuant to which Amdahl and
Fujitsu would participate in the joint development of the Company's next
generation of compatible mainframes.  Under the agreement, Fujitsu will
undertake primary responsibility for the design and manufacture of these
systems.    Also in January 1994 the Company and Fujitsu entered into an
agreement under which Fujitsu would provide loans to the Company in an aggregate
amount not to exceed $100,000,000.  Because of Amdahl's increased dependence on
Fujitsu as its supplier of future large-scale compatible processors and
Fujitsu's participation with the Company in certain other ongoing research and
development activities, the ability to negotiate favorable pricing terms with
respect to future product requirements and to maintain a satisfactory working
relationship are important.


Marketing

          The Company markets its products directly through its sales force to
customers in the United States, Canada, Western Europe and the Pacific Basin,
through Fujitsu in Brazil, Japan,  Malaysia and South Korea and through other
distributors in Saudi Arabia, Latin America and South Africa.  In 1993
approximately 38% of Amdahl's revenues were from international operations.

          The Company offers its products for sale and lease.  For further
information on leasing see "Note 4 - Equipment Leasing and Third Party
Transactions" on pages 21 and 22 of the Annual Report.

          Service for Amdahl products is provided under service and parts
warranty or separate maintenance agreements.  For further information on
warranties, see "Note 1 - Summary of Accounting Policies" on pages 18 and 19 of
the Annual Report.

          While it may receive "letters of intent" and "orders" from potential
customers, typically the Company does not have a firm contract with a customer
until shortly before shipment.  In addition, the Company in many cases will
permit cancellation of an order without charge at any time until actual
delivery, which
<PAGE>
 
is common practice in the industry.  For these reasons, the Company does not
believe indications of customer interest and "orders" constitute a firm
"backlog" and believes that a disclosure of a value of unfilled orders is not a
meaningful indicator of revenues nor material to an understanding of its
business.


Major Customer Information and Geographic Area Data

          The information under "Note 8 - Major Customer, Geographic Area and
Product Line Data" on pages 24 and 25 of the Annual Report is incorporated by
reference.

Competition

          The principal segment of the data processing industry in which the
Company competes remains the highly competitive large-scale computer system and
related storage products and services segment. Amdahl markets its products in
competition with several major multinational companies with substantial
resources. IBM is Amdahl's principal competitor and is dominant in this segment
of the computer industry. Competition is based primarily on price and
performance, product enhancements and new product development, and customer
service and support. However, price/performance relationships can change as new
models or enhancements to existing models are introduced and as prices change.
The financial strength and long-term viability of the supplier are also
important.

          IBM competitive actions in the large-scale computer market and related
submarkets have historically taken the form of price reductions and shortened
product life cycles. As a result, selling prices and residual values of large-
scale computer systems have declined substantially over time. Also, the
continuing introduction by IBM of certain product modifications requires that
Amdahl also make comparable changes to remain fully compatible.  Moreover, IBM
has indicated its intention to utilize lower cost technologies in future
versions of its large-scale computer systems.  While Amdahl has announced
similar intentions, a successful introduction by IBM would require a timely
response by the Company in order to remain competitive on a price/performance
basis.

          The growth in the market for large-scale computers itself has also
been affected by rapid technological changes in recent years which have enabled
smaller, less costly computer systems to compete for the development of
application programs historically run in mainframe environments.

          The areas into which the Company is seeking to diversify its product,
software and service offerings are also intensely competitive. Competitors
include both highly specialized companies as well as fully integrated vendors
such as IBM, Digital Equipment Corporation and Hewlett-Packard Company. New
<PAGE>
 
computer products, particularly in the open systems marketplace, are subject to
rapid technological changes, short product life cycles, frequent product
enhancements and price reductions. For software products, ease of use, product
reliability, quality of technical support and product capabilities are
important. Strength of distribution channels and brand name recognition are also
of great importance.

          While the Company believes that it can compete successfully in its
established and newer areas of business, there remain the inherent risks
attendant with the introduction of new technologies and the Company's lack of
extensive experience in developing product offerings not related to its
traditional compatible processor business.

          For further discussion of competitive conditions, see "Management's
Discussion & Analysis - Results of Operations and Factors That May Affect Future
Operating Results" on pages 31 through 33 of the Annual Report.


Manufacturing

          Amdahl manufactures its computers in Sunnyvale, California, and near
Dublin, Ireland.  Major subsystems and components used in its computers are
manufactured by Amdahl as well as by Fujitsu.  As part of its recently announced
restructuring programs, Amdahl has significantly reduced its manufacturing
capacity, partly to address the lower levels of business experienced in large-
scale mainframes and in anticipation of greater dependence on Fujitsu for the
supply of future mainframe products.

          Amdahl purchases under contracts with Fujitsu certain subassemblies
and substantially all of its large-scale integrated semiconductor components and
high-density printed circuit boards. The FEP and DASD products are manufactured
by Fujitsu to Amdahl specifications.

          While the Company seeks to identify qualified second sources of supply
and to maintain adequate inventories, it may have only one source of supply for
certain critical components, and material interruptions in product shipments
could occur if those components were unavailable for a period of time.  In
addition, if for a substantial period Fujitsu failed to deliver subassemblies,
DASDs or certain other equipment as required under manufacturing agreements with
Amdahl, or should Fujitsu fail to meet development or manufacturing schedules
for future mainframe products, serious interruptions to the Company's delivery
schedules would occur, which would have a material adverse effect on the
Company.

          The current supply agreements between Amdahl and Fujitsu generally
provide for fixed U.S. dollar prices so long as the U.S.-Japanese currency
exchange rate remains within a specified
<PAGE>
 
range.  If the exchange rate fluctuates outside of this range, prices are to be
adjusted pursuant to a formula under which Amdahl and Fujitsu will share equally
any benefits or disadvantages.  For further information regarding purchases from
Fujitsu see "Note 3 - Relationship with Fujitsu Limited" on pages  20 and 21 of
the Annual Report.

Product Development

          The Company's future prospects depend upon its successful development
and introduction of new products.  During the last three years, the Company's
product development costs, including amounts expended on development of both
existing and new products, amounted to $334,514,000 in 1993, $372,365,000 in
1992 and $312,541,000 in 1991.  However, as part of recent restructuring
efforts, the Company has substantially reduced certain of its product
development activities and expects that future product development expenditures
will be considerably below those of recent years.  The Company intends to rely,
to a much greater degree than in the past, on strategic alliances, partnering
arrangements and OEM relationships for major new products or product components.


Patents, Licenses and Related Matters

          Amdahl has an active program to file applications for and obtain
patents in the United States and in selected foreign countries where a potential
market for its products exists.  The Company's general policy has been to seek
patent protection for those inventions and improvements likely to be
incorporated in its products or otherwise expected to be of value.  While Amdahl
believes that its patents and applications have value, it also believes that its
competitive position depends on the ability to successfully enter into
partnering or OEM agreements with outside suppliers and the technical competence
of its development personnel.

          Amdahl and IBM concluded an agreement pursuant to which each party
grants to the other nonexclusive worldwide licenses as to certain of each
other's patents to be issued on patent applications having an effective filing
date prior to January 1, 1998.  Under the agreement, which supersedes prior
agreements between the companies, Amdahl is licensed under substantially all IBM
patents relating to computer systems, communications networks and related
semiconductor technology, generally covering the planned products of the Company
while IBM is licensed under substantially all Amdahl patents.

          The Company has also entered into licensing agreements with others and
contemplates entering into additional license agreements under patents or know-
how in the routine conduct of its business.

             REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULES



To Amdahl Corporation:

     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements included in Amdahl Corporation's Annual
Report to Stockholders incorporated by reference in this Form 10-K, and have
issued our report thereon dated January 31, 1994.  Our audits were made for the
purpose of forming an opinion on those statements taken as a whole.  The
schedules listed under Item 14 are the responsibility of the Company's
management and are presented for purposes of complying with the Securities and
Exchange Commission's rules and are not part of the basic financial statements.
These schedules have been subjected to the auditing procedures applied in the
audit of the basic financial statements and, in our opinion, fairly state in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS



     For the purposes of complying with the amendments to the rules governing
Form S-8 under the Securities Act of 1933, the Company hereby undertakes as
follows:

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or controlling persons of the
Company, the Company has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 1933 Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities registered on the Form S-8 Registration Statements identified below,
the registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

     The preceding undertaking is hereby incorporated by reference to
outstanding Registration Statements Nos. 2-94748, 33-7275, 33-27425, 33-35547
and 33-55460 of the Company on Form S-8.

     Pursuant to the requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934, the registrant has duly caused this report to be signed on
