                                  THE COMPANY
 
     Organized in 1967, Applied Materials, Inc. ("Applied Materials" or the
"Company") develops, manufactures, markets and services semiconductor wafer
fabrication equipment and related spare parts for the worldwide semiconductor
industry. The Company's customers include semiconductor wafer manufacturers and
semiconductor integrated circuit (IC), or "chip," manufacturers. IC
manufacturers either use the chips in their own products or sell them to other
companies. Applied Materials is also a fifty-percent stockholder in Applied
Komatsu Technology, Inc., a joint venture corporation that produces equipment to
fabricate thin film transistors on flat panel displays.
 
PRODUCTS
 
     Applied Materials' products are wafer processing and diagnostic systems
that use highly sophisticated, state-of-the-art technology in the design of
their hardware, process chemistry and software. These systems provide enabling
technology, productivity and cost-effective manufacturing to the customer. The
Company's products are used to fabricate integrated circuits, or "chips," on a
substrate of semiconductor material (usually silicon). A finished IC may consist
of millions of microscopic electronic components that interact to perform
electrical functions. The fabrication process must control the quality of the
film and the preciseness of the individual circuit features to ensure proper
device performance while also meeting economic goals such as high yield and
throughput. The Company currently manufactures equipment that addresses the
following steps in the wafer fabrication process: film deposition, etching, ion
implantation, rapid thermal processing, chemical mechanical polishing, metrology
and wafer/reticle inspection.
 
     Single-wafer, multi-chamber architecture. The trend toward more stringent
process requirements and larger wafer sizes prompted Applied Materials to
develop its first single-wafer, multi-chamber system, called the Precision
5000(R). The Company introduced the Precision 5000 with dielectric chemical
vapor deposition (CVD) processes in 1987, etch processes in 1988 and CVD
tungsten processes in 1989. In addition to the process precision and control
afforded by single-wafer process chambers, the multi-chamber platform concept
provides customers with a significant benefit in processing productivity and
integration. Several process chambers can be "clustered" on a platform, each of
which is attached to a central handling system. This architecture provides a
closed, controlled environment for the wafer and the capability to process
several wafers simultaneously. The Company used its expertise in single-wafer,
multi-chamber architecture to introduce a second single-wafer, multi-chamber
platform called the Endura(R) PVD (physical vapor deposition) in 1990, featuring
a staged, ultra-high vacuum architecture. In September 1992, the Company
announced a third single-wafer, multi-chamber platform, the Centura(R), to
target the high-temperature thin film markets and other mainstream process
applications with 0.5 micron and below specifications. In 1996, the Company
released a fourth single-wafer, multi-chamber platform, called the Optima, for
high-volume CVD applications.
 
PROCESS TECHNOLOGIES
 
     Deposition. Deposition is a fundamental step in fabricating an integrated
circuit. During deposition, a layer of either electrically insulating
(dielectric) or electrically conductive material is deposited on the wafer.
Applied Materials currently provides equipment to perform four main types of
deposition: chemical vapor deposition (CVD), epitaxial deposition, polysilicon
deposition and physical vapor deposition (PVD). The Company has also recently
begun to offer certain types of dielectric deposition processes using its RTP
(rapid thermal processing) XE Centura system.
 
          CVD. Chemical vapor deposition is a process frequently used in
     semiconductor fabrication in which thin films (insulators, conductors and
     semiconductors) are deposited on a wafer from gaseous sources. The Company
     produces the following types of CVD systems:
 
             Dielectric CVD. Dielectric films are used to electrically isolate
        certain areas of the integrated circuit. In 1987, the Company introduced
        the Precision 5000 CVD system which performs a broad range of dielectric
        deposition processes utilizing up to four individual chambers on a
        single system. During the 1990s, a variety of dielectric plasma-enhanced
        CVD process applications were released
 
                                       S-3
<PAGE>   4
 
        on the Precision 5000 and Centura platforms to address customers'
        specific device requirements. In April 1994, the Company released its
        sub-atmospheric (SA) process technology, addressing device geometries to
        0.35 micron. In February 1995, the Company introduced a system using a
        new type of CVD technology known as high-density plasma (HDP), for the
        most advanced CVD applications. HDP-CVD technology is a fast-growing
        sector of the dielectric CVD marketplace.
 
             Metal CVD. Metal films are used in specific areas of the integrated
        circuit to form pathways for electrical current. In 1989, the Company
        entered the market for metal chemical vapor deposition with the
        introduction of a new system for depositing blanket tungsten (W) film,
        the Precision 5000 WCVD. In 1991, the Company introduced CVD tungsten
        silicide capabilities; in 1993, CVD titanium nitride; and in 1996,
        aluminum CVD. By the end of 1996, most of the metal CVD process chambers
        were being shipped on the more advanced Centura platform.
 
          Epitaxial and polysilicon deposition. Epitaxial (epi) deposition, a
     process used for some types of ICs, involves growing a layer of pure
     crystal silicon to form a high quality base for the subsequent device
     circuitry. Applied Materials' experience in epi dates from the Company's
     inception. The Company currently offers two epitaxial systems. The
     Precision 7700 Epi system, introduced in 1989, extends the capabilities of
     batch-type, radiantly-heated barrel technology and incorporates fully
     automated wafer handling. The Epi Centura, introduced in 1993, is a
     single-wafer, multi-chamber epi system for wafers up to 200mm (8 inches) in
     diameter. Polysilicon is a material typically used to form portions of the
     transistor structure on the wafer. In September 1992, the Company announced
     the Poly Centura, a single-wafer, multi-chamber system targeted at the
     deposition of thin polysilicon films at high temperatures on wafers up to
     200mm (8 inches) in diameter.
 
          PVD. Physical vapor deposition is another method used to deposit metal
     films. Unlike CVD in which gases are used, the sources of the deposited
     materials are solid sources called targets. Applied Materials first entered
     the PVD market in April 1990 with the Endura PVD system. This system offers
     a modular, two-stage, single-wafer, multi-chamber platform that
     accommodates both ultra-high vacuum processes like PVD and conventional
     high vacuum processes like CVD and etch. In 1993 and 1994, the Company
     introduced enhanced versions of the Endura system, called the Endura HP PVD
     and Endura VHP(R) PVD systems. A variety of process advancements have also
     been continually introduced to keep pace with customers' changing
     technology requirements. For highly advanced metallization applications,
     the Company now offers integrated combinations of metal CVD and PVD
     processes on the Endura platform.
 
     Etch. Films are selectively removed from the wafer in the etch process.
Before etch processing begins, a wafer is coated with photoresist and exposed to
a circuit pattern during photolithography. Etching removes material only from
areas dictated by the photoresist pattern. Applied Materials entered the etch
market in 1981 with the introduction of the AME 8100 etch system, which utilized
a batch process technology for dry plasma etching. In 1985, the Company
introduced the Precision Etch 8300, which features improved levels of automation
and particulate control. Applied Materials' first single-wafer, multi-chamber
system for the silicon dry etch market was the Precision 5000 Etch, introduced
in 1988. In 1990, the Company introduced a metal etch system based on the
Precision 5000 architecture which provides single-wafer aluminum etch
capabilities. In July 1993, the Company introduced dielectric etching technology
on its next-generation Centura platform, the HDP Dielectric Etch Centura,
designed for applications requiring sub-0.5 micron design rules. Since 1993, the
Company has launched a series of MxP-type process chambers for metal, dielectric
and silicon etching, available on both the Precision 5000 and Centura platforms.
Beginning in 1996, the Company introduced a new series of high-density plasma
etch systems for the most advanced etch applications. The Metal Etch DPS
Centura, the Silicon Etch DPS Centura and the Dielectric Etch IPS Centura now
cover all of the main dry etch market segments.
 
     Ion Implantation. During ion implantation, silicon wafers are bombarded by
a high velocity beam of electrically charged ions. These ions penetrate film
material at selected sites, changing its electrical properties. Applied
Materials entered the high-current portion of the implant market in 1985 with
the Precision Implant 9000 and introduced the Precision Implant 9200 in 1988. In
November 1992, the Company introduced a new
 
                                       S-4
<PAGE>   5
 
high-current ion implantation system, the Precision Implant 9500, for the
production of high density semiconductor devices, such as 16Mb and 64Mb memory
devices and advanced microprocessors. In 1996, the Company introduced a new
series of small footprint implant systems with the Implant xR80, quickly
expanding the line to include the Implant xR120, the Implant xR LEAP (Low Energy
Advanced Processes) and Implant xR200, all with different energy ranges to suit
diverse customer needs.
 
     Rapid Thermal Processing (RTP). RTP is a heat treatment process in which
high-intensity light energy is directed to a wafer for a short period of time,
usually less than 15 seconds. This heat pulse activates and controls the
movement of atoms in the already-deposited film to modify its electrical
properties. Applied Materials entered the fast-growing RTP market in 1995 with
the RTP Centura, whose performance was based on proprietary, leading-edge
advances in thermal measurement and control.
 
     Chemical Mechanical Polishing (CMP). CMP is a material removal process in
which uneven topography on a wafer surface is removed until a flat (planarized)
surface is created. This allows subsequent photolithography processing to take
place with greater accuracy, and enables film layers to be built up with minimal
height variations. The Company announced its entry into the CMP market with the
Mirra CMP in December 1995. The Mirra CMP system features a unique four-station,
three polishing head design that permits continuous processing of several wafers
simultaneously, yet with the precision afforded by single-head process control.
 
     Metrology and Wafer/Reticle Inspection. Applied Materials acquired two
Israeli companies -- Opal, Inc. ("Opal") and Orbot Instruments, Ltd.
("Orbot") -- in the first quarter of fiscal 1997. Opal produces CD-SEM (Critical
Dimension-Scanning Electron Microscope) systems that measure the accuracy of the
circuitry dimensions to assure that manufacturing processes are operating within
specification. Orbot makes two types of inspection tools. One type detects and
classifies defects on semiconductor wafers and the other performs defect
detection on reticles (also called "masks") used by photolithography systems to
pattern wafers.
 
CUSTOMER SERVICE AND SUPPORT
 
     The Company installs equipment and provides warranty service worldwide
through offices located in the United States, Europe, Japan, Korea and
Asia-Pacific (Taiwan, China and Southeast Asia). As of October 27, 1996, the
Company maintained 70 service/sales offices worldwide, with 10 offices in
Europe, 25 offices in Japan, 6 offices in Korea, 5 offices in the Asia-Pacific
region and the remainder in the United States. The Company offers a variety of
service contracts to customers for maintenance of installed equipment and
provides a comprehensive training program for all customers.
 
MARKETING AND SALES
 
     Because of the highly technical nature of its products, the Company markets
its products worldwide through a direct sales force, with sales, service and
spare parts offices in the United States, Europe, Japan, Korea and Asia-Pacific.
For the fiscal year ended October 27, 1996, sales to customers in North America
(primarily the United States), Europe, Japan, Korea and Asia-Pacific accounted
for 31%, 16%, 24%, 14% and 15%, respectively, of the Company's net sales. For
the nine months ended July 27, 1997, sales to customers in North America
(primarily the United States), Europe, Japan, Korea and Asia-Pacific accounted
for 39%, 16%, 16%, 8% and 21%, respectively, of the Company's net sales. The
Company's business is not considered seasonal in nature, but it is cyclical
based on the capital equipment expenditures of major semiconductor
manufacturers. These expenditure patterns are based on many factors, including
anticipated market demand for integrated circuits, the development of new
technologies and global economic conditions.
 
RESEARCH AND DEVELOPMENT
 
     The markets served by the Company are characterized by rapid technological
change. The Company's research and development efforts are global in nature.
Engineering organizations are located in the United States, United Kingdom,
Israel and Japan, with process support and customer demonstration laboratories
in the United States, United Kingdom, Israel, Japan, Korea and Taiwan. Since
1984, the Company has operated
 
                                       S-5
<PAGE>   6
 
a large-scale technology center in Narita, Japan, which has been expanded
several times to meet the requirements of its Japanese customer base. In 1996,
the Company completed construction of new technology centers in Korea and
Taiwan. The Company also operates a technology center in Israel, which is being
used to develop controller configuration and software tools for its
semiconductor processing systems. The Company's research and development
activities are primarily directed toward the development of new wafer processing
and wafer/reticle inspection systems as well as new process applications for
existing products. The Company works closely with its global customers to design
systems to meet its customers' planned technical and production requirements.
 
JOINT VENTURE
 
     In September 1991, the Company announced its plans to develop thin film
transistor (TFT) manufacturing systems for Active-Matrix Liquid Crystal Displays
(AMLCDs). The AMLCD market currently includes screens for laptop, notebook and
palmtop computers, desktop monitors, digital/video cameras, portable televisions
and instrument displays, and may eventually include high-resolution workstations
and High Definition Television (HDTV). In September 1993, the Company and
Komatsu, Ltd. of Japan formed a joint venture corporation, Applied Komatsu
Technology, Inc. (AKT), to target this equipment market. The Company and
Komatsu, Ltd. each own 50% of AKT and the Company accounts for the joint venture
using the equity method. The Company has granted AKT an exclusive license to use
the Company's intellectual property to develop, manufacture, and sell equipment
for the production of flat panel displays, in exchange for royalties in respect
thereof.

(1) The Company's fiscal years end on the last Sunday in October of each year.
 
(2) Share information and per share amounts have been restated to reflect a
    two-for-one stock split in the form of a 100% stock dividend effective
    October 5, 1993, and an additional two-for-one stock split in the form of a
    100% stock dividend effective October 12, 1995, but not the two-for-one
    stock split in the form of a 100% stock dividend to holders of record as of
    September 25, 1997, effective October 13, 1997.
 
(3) In February 1997, the Financial Accounting Standards Board issued Statement
    of Financial Accounting Standard No. 128 (SFAS 128), "Earnings Per Share,"
    which the Company is required to adopt in the first quarter of fiscal 1998.
    Under the requirements of SFAS 128, primary earnings per share will be
    replaced by basic earnings per share and the dilutive effect of stock
    options will be excluded from its calculation. For companies with potential
    dilutive securities such as outstanding stock options, fully diluted
    earnings per share will be replaced with diluted earnings per share. Diluted
    earnings per share are not expected to differ materially from the primary
    earnings per share amounts previously reported by the Company.
 
    The following table presents basic earnings per share for all periods
    presented in this Prospectus Supplement or incorporated by reference into
    the Registration Statement on Form S-3:

(1) Of the authorized shares, as of July 27, 1997, an aggregate of approximately
    17,999,686 shares were reserved for issuance upon exercise of outstanding
    options and an aggregate of approximately 7,092,051 shares were available
    for future grants under the Company's stock option plans. In March 1996, the
    Company was authorized to repurchase up to 5,000,000 shares of its Common
    Stock in the open market during the next three years (until March, 1999),
    which reduces the dilution resulting from the Company's employee benefit and
    incentive plans such as the stock option and employee stock purchase plans.
    As of July 27, 1997, 2,688,000 shares remained available for repurchase
    under such authorization and the "As Adjusted" amounts presented above do
    not reflect the effect of any repurchase of the Company's Common Stock with
    the proceeds from the sale of the Senior Notes (see "Use of Proceeds"). In
    addition, 2,766,115 shares were reserved for issuance under the Company's
    employee stock purchase plan. The share information herein does not give
    effect to the two-for-one stock split of the Company's Common Stock in the
    form of a 100% stock dividend to holders of record as of September 25, 1997,
    effective October 13, 1997.

                        DESCRIPTION OF THE SENIOR NOTES
 
     The following description of the particular terms of the Senior Notes
offered hereby supplements, and to the extent inconsistent therewith replaces,
the description of the general terms and provisions of the Debt Securities set
forth in the accompanying Prospectus, to which description reference is hereby
made. The following summary of the Senior Notes is qualified in its entirety by
reference to the Indenture referred to in the Prospectus. Capitalized terms not
otherwise defined herein or in the accompanying Prospectus have the meanings
given to them in the Indenture.
 
GENERAL
 
     The Senior Notes will be limited to $400,000,000 aggregate principal
amount. The 2007 Senior Notes and 2017 Senior Notes will be limited, with
respect to each series, to $200,000,000 aggregate principal amount, and will
mature on October 15, 2007 and October 15, 2017, respectively. The 2007 Senior
Notes and 2017 Senior Notes will bear interest at the rate of 6.75% per annum
and 7.125% per annum, respectively, each computed on the basis of a 360-day year
of twelve 30-day months, from October 15, 1997, or from the most recent Interest
Payment Date to which interest has been paid or provided for, payable
semiannually on April 15 and October 15 of each year, commencing April 15, 1998,
to the persons in whose names the Senior Notes (or any predecessor Senior Notes)
are registered at the close of business on April 1 or October 1, as the case may
be, next preceding such Interest Payment Date. The Senior Notes are not entitled
to the benefit of any sinking fund. The Senior Notes will be issued only in
registered form in denominations of $1,000 and any integral multiple thereof.
 
     The Senior Notes will be senior unsecured general obligations of the
Company that will rank on a parity with all other unsecured and unsubordinated
indebtedness of the Company from time to time outstanding. The defeasance and
covenant defeasance provisions of the Indenture described under the caption
"Description of Debt Securities -- Defeasance and Covenant Defeasance" in the
accompanying Prospectus will apply to the Senior Notes.
 
REDEMPTION OF THE SENIOR NOTES AT THE OPTION OF THE COMPANY
 
     The Senior Notes will be redeemable, in whole or in part, at the option of
the Company at any time, at a redemption price equal to the greater of (i) 100%
of the principal amount of such Senior Notes and (ii) the sum of the present
values of the remaining scheduled payments of principal and interest thereon
discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate plus 15 (fifteen) basis
points and 15 (fifteen) basis points in case of the 2007 Senior Notes and the
2017 Senior Notes, respectively, plus, in each case, accrued interest thereon to
the date of redemption.
 
     "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.
 
     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Senior Notes to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such Senior Notes. "Independent Investment Banker" means
Morgan Stanley & Co. Incorporated or, if such firm is unwilling or unable to
select the Comparable Security Issue, one of the other Reference Treasury
Dealers appointed by the Trustee after consultation with the Company.
 
     "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities," or (ii) if such release (or any successor release) is
not
 
                                      S-10
<PAGE>   11
 
published or does not contain such prices on such business day, (A) the average
of the Reference Treasury Dealer Quotations for such redemption date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Quotations. "Reference Treasury Dealer
Quotations" means, with respect to each Reference Treasury Dealer and any
redemption date, the average, as determined by the Trustee, of the bid and asked
prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Trustee by such Reference
Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption
date.
 
     "Reference Treasury Dealer" means (i) each of Morgan Stanley & Co.
Incorporated, Lehman Brothers Inc., Goldman, Sachs & Co., J.P. Morgan Securities
Inc. and their respective successors; provided, however, that if any of the
foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), the Company shall substitute therefor
another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer
selected by the Trustee after consultation with the Company.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Senior Notes to be
redeemed.
 
BOOK-ENTRY SYSTEM
 
     The Senior Notes will be in the form of one or more Global Securities
registered in the name of a nominee of The Depository Trust Company, as
Depositary. The provisions set forth under "Description of Debt
Securities -- Book-Entry System" in the accompanying Prospectus will be
applicable to the Senior Notes.

</TABLE>
 
     The Underwriting Agreement provides that the obligation of the several
Underwriters to pay for and accept delivery of the Senior Notes is subject to
the approval of certain legal matters by their counsel and to certain other
conditions. The Underwriters are obligated to take and pay for all of the Senior
Notes if any are taken.
 
     The Underwriters initially propose to offer part of the Senior Notes
directly to the public at the public offering price set forth on the cover page
hereof and part to certain dealers at a price that represents a concession not
in excess of .40% of the principal amount in the case of the 2007 Senior Notes
and .50% of the principal amount in the case of the 2017 Senior Notes. Any
Underwriter may allow, and such dealers may reallow, a concession not in excess
of .25% of the principal amount in the case of the 2007 Senior Notes and .25% of
the principal amount in the case of the 2017 Senior Notes to certain other
dealers. After the initial offering of the Senior Notes, the offering price and
other selling terms may from time to time be varied by the Underwriters.
 
     The Company has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended.
 
     The Company does not intend to apply for listing of the Senior Notes on a
national securities exchange, but has been advised by the Underwriters that they
presently intend to make a market in the Senior Notes, as permitted by
applicable laws and regulations. The Underwriters are not obligated, however, to
make a market in the Senior Notes and any such market-making may be discontinued
at any time at the sole discretion of the Underwriters. Accordingly, no
assurance can be given as to the liquidity of, or trading markets for, the
Senior Notes. The Underwriters do not intend to confirm sales to accounts over
which they exercise discretionary authority.
 
     From time to time, certain of the Underwriters or their affiliates have
provided, and may continue to provide, investment banking and/or commercial
banking services to the Company.
 
     In order to facilitate the offering of the Senior Notes, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Senior Notes. In addition, to stabilize the price of the Senior
Notes, the Underwriters may bid for, and purchase, the Senior Notes in the open
market. Finally, the Underwriters may reclaim selling concessions allowed to an
Underwriter or a dealer for distributing the Senior Notes in the offering, if
the Underwriter repurchases previously distributed Senior Notes in transactions
to cover Underwriter short positions, in stabilization transactions or
otherwise. Any of these activities may stabilize or maintain the market price
for the Senior Notes above independent market levels. The Underwriters are not
required to engage in these activities and may end any of these activities at
any time.

                                  THE COMPANY
 
     Organized in 1967, Applied Materials, Inc. ("Applied Materials" or the
"Company") develops, manufactures, markets and services semiconductor wafer
fabrication equipment and related spare parts for the worldwide semiconductor
industry. The Company's customers include semiconductor wafer manufacturers and
semiconductor integrated circuit (IC), or "chip," manufacturers. IC
manufacturers either use the chips in their own products or sell them to other
companies. Applied Materials is also a fifty percent stockholder in Applied
Komatsu Technology, Inc., a joint venture corporation that develops,
manufactures, markets and services thin film transistor fabrication systems used
to produce active-matrix liquid crystal displays.
 
     The Company's products are wafer processing and diagnostic systems that use
highly sophisticated, state-of-the-art technology in the design of their
hardware, processes and software. These systems provide enabling technology,
productivity and cost-effective manufacturing to the customer. The Company's
products are used to fabricate integrated circuits, or "chips," on a substrate
of semiconductor material (usually silicon). A finished IC may consist of
millions of microscopic electronic components that interact to perform
electrical functions. The fabrication process must control the quality of the
film and the preciseness of the individual circuit features to ensure proper
device performance while also meeting economic goals such as high yield and
throughput. The Company currently manufactures equipment that addresses the
following major steps in the wafer fabrication process: film deposition,
etching, ion implantation, rapid thermal processing, high-temperature
processing, chemical mechanical polishing, metrology and wafer/reticle
inspection.
 
     The Company was incorporated in California in 1967 and reincorporated in
Delaware in 1987. Its principal executive offices are located at 3050 Bowers
Avenue, Santa Clara, California 95054-3299 (telephone number (408) 727-5555).
References to the Company or to Applied Materials shall mean Applied Materials,

                                USE OF PROCEEDS
 
     The Company expects to use the net proceeds from the sale of the Debt
Securities for general corporate purposes, including capital expenditures and
working capital needs, and a portion may be used to repurchase shares of the
Company's outstanding Common Stock. The Company believes that success in its
industry requires substantial financial strength and flexibility. In addition,
the Company from time to time considers acquisitions of, and investments in,
complementary businesses, assets or technologies, and although there are no
current agreements with respect to any such acquisition or investment, the
Company desires to be able to respond to opportunities as they arise. Pending
such uses, the Company will invest the net proceeds in cash equivalents and
short-term investments.

<PAGE>   18
 
portion thereof, called for redemption, except the unredeemed portion of any
Debt Security being redeemed in part. (Section 305)
 
BOOK-ENTRY SYSTEM
 
     The provisions set forth below will apply to the Debt Securities of any
series if the Prospectus Supplement relating to such series so indicates.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Debt Securities will be represented by one or more fully registered global
securities (collectively, a "Global Note") which will be deposited with, or on
behalf of, The Depository Trust Company, New York, New York, as Depositary, and
registered in the name of the Depositary's nominee. Except as set forth below,
the Global Note may be transferred, in whole and not in part, only to the
Depositary or another nominee of the Depositary.
 
     The Depositary has advised the Company and the Underwriters as follows: The
Depositary is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. The Depositary holds securities
that its participants ("Participants") deposit with the Depositary. The
Depositary also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations ("Direct Participants").
The Depositary is owned by a number of its Direct Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc., and the National
Association of Securities Dealers, Inc. Access to the Depositary system is also
available to others such as securities brokers and dealers, banks, and trust
companies that clear through or maintain a custodial relationship with a Direct
Participant, either directly or indirectly ("Indirect Participants"). The rules
applicable to the Depositary and its Participants are on file with the
Commission.
 
     Purchases of interests in a Global Note under the Depositary system must be
made by or through Direct Participants, which will receive a credit for such
interests in the Depositary's records. The ownership interest of each actual
purchaser of interests in a Global Note ("Beneficial Owner") is in turn to be
recorded on the Direct and Indirect Participants' records. Beneficial Owners
will not receive written confirmation from the Depositary of their purchase, but
Beneficial Owners are expected to receive written confirmations providing
details of the transaction, as well as periodic statements of their holdings,
from the Direct or Indirect Participant through which the Beneficial Owner
entered into the transaction. Transfers of ownership interests in a Global Note
are to be accomplished by entries made on the books of Participants acting on
behalf of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interests in a Global Note, except as described
below. The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and laws may impair the ability to transfer beneficial interests in a
Global Note.
 
     So long as the Depositary, or its nominee, is the registered holder and
owner of a Global Note, the Depositary or such nominee, as the case may be, will
be considered the sole owner and holder of the related Debt Security for all
purposes of such Debt Security and for all purposes under the Indenture. Except
as set forth below, owners of beneficial interests in a Global Note will not be
entitled to have the Debt Securities represented by such Global Note registered
in their names, will not receive or be entitled to receive physical delivery of
Debt Securities in definitive form and will not be considered to be the owners
or holders of any Debt Securities under the Indenture or such Global Note.
Accordingly, each person owning a beneficial interest in a Global Note must rely
on the procedures of the Depositary and, if such person is not a Participant, on
the procedures of the Participant through which such person owns its interest,
to exercise any rights of a holder of Debt Securities under the Indenture. The
Company understands that under existing industry practice, in the event the
Company requests any action of holders of Senior Notes or if an owner of a
beneficial interest in a Global Note desires to take any action that the
Depositary, as the holder of such Global Note, is
 
                                        6
<PAGE>   19
 
entitled to take, the Depositary would authorize the Participants to take such
action, and that the Participants would authorize beneficial owners owning
through such Participants to take such action or would otherwise act upon the
instructions of beneficial owners owning through them.
 
     To facilitate subsequent transfers, a Global Note deposited with the
Depositary is registered in the name of the Depositary's partnership nominee,
Cede & Co. The deposit of a Global Note with the Depositary and its registration
in the name of Cede & Co. effects no change in beneficial ownership. The
Depositary has no knowledge of the actual Beneficial Owners of the interests in
a Global Note; the Depositary's records reflect only the identity of the Direct
Participants to whose accounts interests in the Global Note are credited, which
may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
 
     Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Principal and interest payments on a Global Note will be made to the
Depositary or its nominee, as the case may be, as the registered owner and
holder of such Global Note. The Depositary's practice is to credit Direct
Participants' accounts on the payment date in accordance with their respective
holdings shown on the Depositary's records unless the Depositary has reason to
believe that it will not receive payment on the payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions and
customary practices, as is the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such Participant and not of the Depositary, the Paying Agent,
or the Company, subject to any statutory or regulatory requirements as may be in
effect from time to time. Payment of principal and interest to the Depositary is
the responsibility of the Company or the Paying Agent, disbursement of such
payments to Direct Participants shall be the responsibility of the Depositary,
and disbursement of such payments to the Beneficial Owners shall be the
responsibility of Direct and Indirect Participants.
 
     The Depositary may discontinue providing its services as depositary with
respect to the Debt Securities at any time by giving reasonable notice to the
Company or the Paying Agent. Under such circumstances, in the event that a
successor depositary is not obtained, definitive Debt Securities certificates
are required to be printed and delivered.
 
     Unless otherwise provided in the applicable Prospectus Supplement the Debt
Securities represented by a Global Note will be exchangeable for Debt Securities
in definitive form of like tenor as such Global Note in denominations of $1,000
and in any greater amount that is an integral multiple thereof if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Note or if at any time the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, (ii) the
Company in its discretion at any time determines not to have all of the Debt
Securities represented by a Global Note and notifies the Trustee thereof or
(iii) an Event of Default has occurred and is continuing with respect to the
Debt Securities. Any Debt Security that is exchangeable pursuant to the
preceding sentence is exchangeable for Debt Securities issuable in authorized
denominations and registered in such names as the Depositary shall instruct the
Trustee. It is expected that such instructions may be based upon directions
received by the Depositary from its participants with respect to ownership of
beneficial interests in such Global Note. Subject to the foregoing, a Global
Note is not exchangeable, except for a Global Note or Global Notes of the same
aggregate denominations to be registered in the name of the Depositary or its
nominee.
 
     The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that the Company
believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.

COVENANTS OF THE COMPANY
 
     Except as set forth below or as otherwise provided in the applicable
Prospectus Supplement with respect to any series of Debt Securities, the Company
is not restricted by the Indenture from incurring, assuming or becoming liable
for any type of debt or other obligations, from paying dividends or making
distributions on its capital stock or purchasing or redeeming its capital stock.
The Indenture does not require the maintenance of any financial ratios or
specified levels of net worth or liquidity. In addition, the Indenture does not
contain any provision that would require the Company to repurchase or redeem or
otherwise modify the terms of any of its Debt Securities upon a change in
control or other events involving the Company which may adversely affect the
creditworthiness of the Debt Securities.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, certain
covenants contained in the Indenture which are summarized below will be
applicable (unless waived or amended) to the series of Debt Securities to which
such Prospectus Supplement relates so long as any of the Debt Securities of such
series are outstanding.
 
     Limitations on Liens. The Company covenants that it will not issue, incur,
create, assume or guarantee, and will not permit any Restricted Subsidiary to
issue, incur, create, assume or guarantee, any debt for borrowed money secured
by a mortgage, security interest, pledge, lien, charge or other encumbrance
("mortgages") upon any Principal Property or Domestic Receivables or Inventory
of the Company or any Restricted Subsidiary or upon any shares of stock or
indebtedness of any Restricted Subsidiary (whether such Principal Property, or
Domestic Receivables or Inventory, shares or indebtedness are now existing or
owed or hereafter created or acquired) without in any such case effectively
providing concurrently with the issuance, incurrence, creation, assumption or
guaranty of any such secured debt that the Debt Securities (together with, if
the Company shall so determine, any other indebtedness of or guarantee by the
Company or such Restricted Subsidiary ranking equally with the Debt Securities)
shall be secured equally and ratably with (or, at the option of the Company,
prior to) such secured debt. The foregoing restriction, however, will not apply
to: (a) mortgages on property, shares of stock or indebtedness or other assets
of any corporation existing at the time such corporation becomes a Restricted
Subsidiary, provided that such mortgages or liens are not incurred in
anticipation of such corporation becoming a Restricted Subsidiary; (b)(i)
mortgages on property, shares of stock, indebtedness or other assets existing at
the time of acquisition thereof by the Company or a Restricted Subsidiary (which
may include property previously leased by the Company and leasehold interests
thereon, provided that the lease terminates prior to the acquisition) or
mortgages thereon to secure the payment of all or any part of the purchase price
thereof, or (ii) mortgages on property, shares of stock, indebtedness or other
assets to secure any indebtedness for borrowed money incurred prior to, at the
time of, or within 270 days after, the latest of the acquisition thereof, or, in
the case of property, the completion of construction, the completion of
improvements or the commencement of substantial commercial operation of such
property for the purpose of financing all or any part of the purchase price
thereof, such construction or the making of such improvements; (c) mortgages to
secure indebtedness owing to the Company or to a Restricted Subsidiary; (d)
mortgages existing at the date of the initial issuance of the Securities of such
series; (e) mortgages on property or other assets of a corporation existing at
the time such corporation is merged into or consolidated with the Company or a
Restricted Subsidiary or at the time of a sale, lease or other disposition of
the properties of a corporation as an entirety or substantially as an entirety
to the Company or a Restricted Subsidiary, provided that such mortgage was not
incurred in anticipation of such merger or consolidation or sale, lease or other
disposition; (f) mortgages in favor of the United States of America or any
State, territory or possession thereof (or the District of Columbia), or any
department, agency, instrumentality or political subdivision of the United
States of America or any State, territory or possession thereof (or the District
of Columbia), to secure partial, progress, advance or other payments pursuant to
any contract or statute or to secure any indebtedness incurred for the purpose
of financing all or any part of the purchase price or the cost of constructing
or improving the property subject to such mortgages; or (g) extensions, renewals
or replacements of any mortgage referred to in the foregoing clauses (a) through
(f); provided, however, that any mortgages permitted by any of the foregoing
clauses (a) through (f) shall not extend to or cover any property of the Company
or such Restricted Subsidiary, as the case may be, other than the property
specified in such clauses and improvements thereto. (Section 1008)
 
                                        8
<PAGE>   21
 
     Notwithstanding the restrictions outlined in the preceding paragraph, the
Company or any Restricted Subsidiary may issue, incur, create, assume or
guarantee debt secured by a mortgage which would otherwise be subject to such
restrictions, without equally and ratably securing the Debt Securities, provided
that after giving effect thereto, the aggregate amount of all debt so secured by
mortgages (not including mortgages permitted under clauses (a) through (g)
above) does not exceed 10% of the Consolidated Net Tangible Assets of the
Company. (Section 1008)
 
     Limitations on Sale and Lease-Back Transactions. The Company covenants that
it will not, nor will it permit any Restricted Subsidiary to, enter into any
Sale and Lease-Back Transaction with respect to any Principal Property, other
than any such transaction involving a lease for a term of not more than three
years or any such transaction between the Company and a Restricted Subsidiary or
between Restricted Subsidiaries, unless: (a) the Company or such Restricted
Subsidiary would be entitled to incur indebtedness secured by a mortgage on the
Principal Property involved in such transaction at least equal in amount to the
Attributable Debt with respect to such sale and lease-back transaction, without
equally and ratably securing the Debt Securities, pursuant to the limitation in
the Indenture on liens; or (b) the Company shall apply an amount equal to the
greater of the net proceeds of such sale or the Attributable Debt with respect
to such sale and lease-back transaction within 180 days of such sale to either
(or a combination of) (i) the retirement (other than any mandatory retirement,
mandatory prepayment or sinking fund payment or by payment at maturity) of debt
for borrowed money of the Company or a Restricted Subsidiary that matures more
than twelve months after the creation of such indebtedness or (ii) the purchase,
construction or development of other comparable property. (Section 1009)
 
     Certain Definitions Applicable to Covenants. The term "Attributable Debt"
when used in connection with a Sale and Lease-Back Transaction involving a
Principal Property shall mean, at the time of determination, the lesser of: (a)
the fair value of such property (as determined in good faith by the Board of
Directors of the Company); or (b) the present value of the total net amount of
rent required to be paid under such lease during the remaining term thereof
(including any renewal term or period for which such lease has been extended),
discounted at the rate of interest set forth or implicit in the terms of such
lease or, if not practicable to determine such rate, the weighted average
interest rate per annum borne by the Debt Securities of each series outstanding
pursuant to the Indenture compounded semi-annually, in either case as determined
in good faith by the principal accounting or financial officer of the Company.
For purposes of the foregoing definition, rent shall not include amounts
required to be paid by the lessee, whether or not designated as rent or
additional rent, on account of or contingent upon maintenance and repairs,
insurance, taxes, assessments, water rates and similar charges. In the case of
any lease which is terminable by the lessee upon the payment of a penalty, such
net amount shall be the lesser of the net amount determined assuming termination
upon the first date such lease may be terminated (in which case the net amount
shall also include the amount of the penalty, but no rent shall be considered as
required to be paid under such lease subsequent to the first date upon which it
may be so terminated) or the net amount determined assuming no such termination.
 
     The term "Consolidated Net Tangible Assets" shall mean, as of any
particular time, the aggregate amount of assets (less applicable reserves and
other properly deductible items) after deducting therefrom: (a) all current
liabilities, except for (1) notes and loans payable, (2) current maturities of
long-term debt and (3) current maturities of obligations under capital leases;
and (b) certain intangible assets, to the extent included in said aggregate
amount of assets, all as set forth on the most recent consolidated balance sheet
of the Company and its consolidated subsidiaries and computed in accordance with
generally accepted accounting principles.
 
     The term "Domestic Receivables or Inventory" shall mean accounts receivable
arising from the sale of inventory or inventory owned by the Company or any
Subsidiary whose principal place of business and place of incorporation is
located in the United States of America. For purposes hereof, inventory and
receivables shall be deemed to be "owned" if they are deemed to be assets of the
Company or such Subsidiary for purposes of generally accepted accounting
principles.
 
     The term "Principal Property" shall mean the land, land improvements,
buildings and fixtures (to the extent they constitute real property interests)
(including any leasehold interest therein) constituting the
 
                                        9
<PAGE>   22
 
principal corporate office, any manufacturing plant or any manufacturing
facility (whether now owned or hereafter acquired) and the equipment located
thereon which: (a) is owned by the Company or any Subsidiary; (b) is located
within any of the present 50 States of the United States of America (or the
District of Columbia); (c) has not been determined in good faith by the Board of
Directors of the Company not to be materially important to the total business
conducted by the Company and its Subsidiaries taken as a whole; and (d) has a
book value on the date as of which the determination is being made in excess of
0.75% of Consolidated Net Tangible Assets of the Company as most recently
determined on or prior to such date (including for purposes of such calculation
the land, land improvements, buildings and such fixtures compromising such
office, plant or facilities, as the case may be).
 
     The term "Restricted Subsidiary" shall mean any Subsidiary which owns any
Principal Property or Domestic Receivables or Inventory; provided, however, that
the term "Restricted Subsidiary" shall not include any Subsidiary which is
principally engaged in financing the Company's operations outside the United
States of America; and provided, further, that the term "Restricted Subsidiary"
shall not include any Subsidiary less than 80% of the voting stock of which is
owned, directly or indirectly, by the Company or by one or more other
Subsidiaries, or by the Company and one or more other Subsidiaries if the common
stock of such Subsidiary is traded on any national securities exchange or quoted
on the Nasdaq National Market or in the over-the-counter market. None of the
Company's Subsidiaries is currently a Restricted Subsidiary.
 
     The term "Sale and Lease-Back Transaction" shall mean any arrangement with
any Person providing for the leasing by the Company or any Restricted Subsidiary
of any Principal Property which property has been or is to be sold or
transferred by the Company or such Restricted Subsidiary to such Person.
 
     The term "Subsidiary" shall mean any corporation of which at least 66 2/3%
of the outstanding stock having the voting power to elect a majority of the
board of directors of such corporation is at the time owned, directly or
indirectly, by the Company or by one or more other Subsidiaries, or by the
Company and one or more other Subsidiaries. For the purposes of this definition,
"voting stock" means stock which ordinarily has voting power for the election of
directors, whether at all times or only so long as no senior class of stock has
such voting power by reason of any contingency.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
     The Indenture provides that, if such provision is made applicable to the
Debt Securities of any series pursuant to the provisions of the Indenture, the
Company may elect (i) to defease and be discharged from any and all obligations
in respect of such Debt Securities except for the rights of holders to receive
payments in respect of the principal of and any premium and interest on such
Debt Securities and for certain obligations to register the transfer or exchange
of such Debt Securities, to replace temporary, destroyed, stolen, lost or
mutilated Debt Securities, to maintain paying agencies and to hold monies for
payment in trust ("defeasance") or (ii) (A) to omit to comply with certain
restrictive covenants in Sections 1005 through 1010 (including the covenants
referred to above under "Covenants of the Company") and (B) to deem the
occurrence of any event referred to in clauses (d) (with respect to Sections
1005 through 1010 inclusive) and (g) under "Events of Default" below not to be
or result in an Event of Default if, in each case with respect to the
Outstanding Debt Securities of such series as provided in Section 1303 on or
after the date the conditions set forth in Section 1304 are satisfied ("covenant
defeasance"), in either case upon the deposit with the Trustee (or other
qualifying trustee), in trust, of money and/or U.S. Government Obligations,
which through the payment of interest and principal in respect thereof in
accordance with their terms will provide money in an amount sufficient to pay
the principal of and any premium and interest on the Debt Securities of such
series on the respective Stated Maturities and any mandatory sinking fund
payments or analogous payments on the days payable, in accordance with the terms
of the Indenture and the Debt Securities of such series. Such a trust may only
be established if, among other things, the Company has delivered to the Trustee
an Opinion of Counsel to the effect that the Holders of the Outstanding Debt
Securities of such series will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit, defeasance or covenant
defeasance and will be subject to Federal income tax on the same amount, and in
the same manner and at the same times as would have been the case if such
deposit, defeasance or covenant defeasance had not occurred. Such opinion, in
the case of defeasance under clause (i) above, must refer to and be based upon a
ruling of the
 
                                       10
<PAGE>   23
 
Internal Revenue Service or a change in applicable Federal income tax laws
occurring after the date of the Indenture. The Prospectus Supplement relating to
a series may further describe the provisions, if any, permitting such defeasance
or covenant defeasance with respect to the Debt Securities of a particular
series. (Article Thirteen)
 
EVENTS OF DEFAULT
 
     Any one of the following events will constitute an Event of Default under
the Indenture with respect to Debt Securities of any series (unless such event
is specifically inapplicable to a particular series as described in the
Prospectus Supplement relating thereto): (a) failure to pay any interest on any
Debt Security of that series when due, continued for 30 days; (b) failure to pay
principal of or any premium on any Debt Security of that series when due; (c)
failure to deposit any sinking fund payment, when due, in respect of any Debt
Security of that series; (d) failure to perform any other covenant of the
Company in the Indenture (other than a covenant included in the Indenture solely
for the benefit of a series of Debt Securities other than that series),
continued for 90 days after written notice as provided in the Indenture; (e)
certain events in bankruptcy, insolvency or reorganization involving the
Company; (f)(i) failure of the Company to make any payment at maturity,
including any applicable grace period, in respect of indebtedness, which term as
used in the Indenture means obligations (other than non-recourse obligations or
the Debt Securities of such series) of the Company for borrowed money or
evidenced by bonds, debentures, notes or similar instruments ("Indebtedness") in
an amount in excess of $25,000,000 and continuance of such failure or (ii) a
default with respect to any Indebtedness, which default results in the
acceleration of Indebtedness in an amount in excess of $25,000,000 without such
Indebtedness having been discharged or such acceleration having been cured,
waived, rescinded or annulled, in the case of (i) or (ii) above, for a period of
30 days after written notice thereof to the Company by the Trustee or to the
Company and the Trustee by the holders of not less than 15% in principal amount
of Debt Securities of such series; provided, however, that if any such failure,
default or acceleration referred to in (i) or (ii) above shall cease or be
cured, waived, rescinded or annulled, then the Event of Default by reason
thereof shall be deemed likewise to have been thereupon cured; and (g) any other
Event of Default provided with respect to Debt Securities of that series.
(Section 501)
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee during default to act with the required standard of care, the Trustee is
under no obligation to exercise any of its rights or powers under the Indenture
at the request or direction of any of the Holders, unless such Holders shall
have offered to the Trustee reasonable indemnity. (Sections 601 and 603) Subject
to such provisions for the indemnification of the Trustee, the Holders of a
majority in principal amount of the Outstanding Debt Securities of any series
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, with respect to the Debt Securities of that series.
(Section 512)
 
     The Indenture provides that the Company will deliver to the Trustee, within
120 days after the end of each fiscal year, a brief certificate from the
principal executive, financial or accounting officer of the Company as to his or
her knowledge of the Company's compliance (without regard to any period of grace
or requirement of notice) with all conditions and covenants of the Indenture.
(Section 1004)
 
     If an Event of Default with respect to Debt Securities of any series at the
time Outstanding occurs and is continuing, either the Trustee or the Holders of
at least 25% in principal amount of the Outstanding Debt Securities of that
series by notice as provided in the Indenture may declare the principal amount
(or, if the Debt Securities of that series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) of all the Debt Securities of that series to be due and
payable immediately. At any time after a declaration of acceleration with
respect to Debt Securities of any series has been made, but before a judgment or
decree for payment of money has been obtained by the Trustee, the Holders of a
majority in principal amount of the Outstanding Debt Securities of that series
may, under certain circumstances, rescind and annul such acceleration. (Section
502)
 
     No Holder of any Debt Security of any series has any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written
 
                                       11
<PAGE>   24
 
notice of a continuing Event of Default and unless the Holders of at least 25%
in principal amount of the Outstanding Debt Securities of that series shall have
made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in principal amount of the Outstanding Debt
Securities of that series a direction inconsistent with such request and shall
have failed to institute such proceeding within 60 days. (Section 507) However,
such limitations generally do not apply to a suit instituted by a Holder of a
Debt Security for the enforcement of payment of the principal or interest on
such Debt Security on or after the respective due dates expressed in such Debt
Security. (Section 508)
 
MEETINGS, MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority in
principal amount of the Outstanding Debt Securities of each series affected by
such modification or amendment; provided, however that no such modification or
amendment may, without the consent of the Holder of each Outstanding Debt
Security affected thereby, (a) change the Stated Maturity of the principal of,
or any installment of principal of or interest on, any Debt Security, (b) reduce
the principal amount of, rate of interest on or any premium payable upon the
redemption of any Debt Security, (c) reduce the amount of principal of an
Original Issue Discount Security payable upon acceleration of the Maturity
thereof, (d) change the Place of Payment where, or the coin or currency in
which, any Debt Security or any premium or interest thereon is payable, (e)
impair the right to institute suit for the enforcement of any payment on or with
respect to any Debt Security after the Stated Maturity, Redemption Date or
Repayment Date, (f) reduce the percentage in principal amount of Outstanding
Debt Securities of any series, the consent of whose Holders is required for
modification or amendment of the Indenture or for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults, or (g)
modify any of the provisions set forth in this paragraph except to increase any
such percentage or to provide that certain other provisions of the Indenture may
not be modified or waived without the consent of the Holder of each Outstanding
Debt Security affected thereby. (Section 902)
 
     The Holders of at least a majority in principal amount of the Outstanding
Debt Securities of each series may, on behalf of the Holders of all the Debt
Securities of that series, waive, insofar as that series is concerned,
compliance by the Company with certain restrictive provisions of the Indenture.
(Section 1011) The Holders of not less than a majority in principal amount of
the Outstanding Debt Securities of each series may, on behalf of all Holders of
Debt Securities of that series and any coupons appertaining thereto, waive any
past default under the Indenture with respect to Debt Securities of that series,
except a default (a) in the payment of principal of or any premium or interest
on any Debt Security of such series or (b) in respect of a covenant or provision
of the Indenture which cannot be modified or amended without the consent of the
Holder of each Outstanding Debt Security of such series affected. (Section 513)
 
     The Indenture provides that in determining whether the Holders of the
requisite principal amount of the Outstanding Debt Securities have given any
request, demand, authorization, direction, notice, consent or waiver thereunder
or whether a quorum is present at a meeting of Holders of Debt Securities (i)
the principal amount of an Original Issue Discount Security that shall be deemed
to be Outstanding shall be the amount of the principal thereof that would be due
and payable as of the date of such determination upon acceleration of the
Maturity thereof, (ii) the principal amount of a Debt Security denominated in
other than U.S. dollars shall be the U.S. dollar equivalent, determined on the
date of original issuance of such Debt Security, of the principal amount of such
Debt Security (or, in the case of an Original Issue Discount Security, the U.S.
dollar equivalent on the date of original issuance of such Debt Security of the
amount determined as provided in (i) above of such Debt Security) and (iii) Debt
Securities owned by the Company or any Affiliate of the Company shall be
disregarded and deemed not to be Outstanding. (Section 101)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Company, without the consent of the Holders of any of the Outstanding
Debt Securities under the Indenture, may consolidate with or merge into, or
transfer or lease its assets substantially as an entirety to, any Person which
is a corporation, partnership or trust organized and validly existing under the
laws of any
 
                                       12
<PAGE>   25
 
domestic jurisdiction, provided that any successor Person expressly assumes the
Company's obligations on the Debt Securities and under the Indenture and that,
after giving effect to the transaction, no Event of Default, and no event which,
after notice or lapse of time, would become an Event of Default, shall have
occurred and be continuing, and that certain other conditions are met. (Section
801)
 
NOTICES
 
     Except as otherwise provided in the Indenture, notices to Holders of Debt
Securities will be given by mail to the addresses of such Holders as they appear
in the Debt Security Register. (Section 106)
 
TITLE
 
     Prior to due presentment of a Debt Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Debt Security is registered as the owner of such
Debt Security for the purpose of receiving payment of principal of and any
premium and any interest (other than Defaulted Interest or as otherwise provided
in the applicable Prospectus Supplement) on such Debt Security and for all other
purposes whatsoever, whether or not such Debt Security be overdue, and neither
the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. (Section 308)
 
REPLACEMENT OF DEBT SECURITIES
 
     Any mutilated Debt Security will be replaced by the Company at the expense
of the Holder upon surrender of such Debt Security to the Trustee. Debt
Securities that become destroyed, stolen or lost will be replaced by the Company
at the expense of the Holder upon delivery to the Trustee of the Debt Security
or evidence of the destruction, loss or theft thereof satisfactory to the
Company and the Trustee. In the case of a destroyed, lost or stolen Debt
Security, an indemnity satisfactory to the Trustee and the Company may be
required at the expense of the Holder of such Debt Security before a replacement
Debt Security will be issued. (Section 306)
 
GOVERNING LAW
 
     The Indenture and the Debt Securities will be governed by, and construed in
accordance with, the laws of the State of New York. (Section 112)
 
REGARDING THE TRUSTEE
 
     The Indenture contains certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize for its own account on certain property received in
respect of any such claim as security or otherwise. (Section 613) The Trustee is
permitted to engage in certain other transactions; however, if it acquires any
conflicting interest and there is a default under the Debt Securities of any
series for which the Trustee serves as trustee, the Trustee must eliminate such
conflict or resign. (Section 608)
 
     The Trustee currently provides certain banking and financial services to
the Company in the ordinary course of business and may provide other such
services in the future.
 
                                       13
<PAGE>   26
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Debt Securities (i) to one or more underwriters or
dealers for public offering and sale by them and (ii) to investors directly or
through agents. The distribution of the Debt Securities may be effected from
time to time in one or more transactions at a fixed price or prices (which may
be changed from time to time), at market prices prevailing at the time of sale,
at prices related to such prevailing market prices or at negotiated prices. Each
Prospectus Supplement will describe the method of distribution of the Debt
Securities offered thereby.
 
     In connection with the sale of the Debt Securities, underwriters, dealers
or agents may receive compensation from the Company or from purchasers of the
Debt Securities for whom they may act as agents, in the form of discounts,
concessions or commissions. The underwriters, dealers or agents which
participate in the distribution of the Debt Securities may be deemed to be
underwriters under the Securities Act of 1933 and any discounts or commissions
received by them and any profit on the resale of the Debt Securities received by
them may be deemed to be underwriting discounts and commissions thereunder. Any
such underwriter, dealer or agent will be identified and any such compensation
received from the Company will be described in the Prospectus Supplement. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
     Under agreements that may be entered into with the Company, underwriters,
dealers and agents may be entitled to indemnification by the Company against
certain civil liabilities, including liabilities under the Securities Act of
1933, or to contribution with respect to payments which the underwriters,
dealers or agents may be required to make in respect thereof.
 
     All Debt Securities will be new issues of securities with no established
trading market. Any underwriters to whom Debt Securities are sold by the Company
for public offering and sale may make a market in such securities, but such
underwriters will not be obligated to do so and may discontinue any market
making at any time without notice. No assurance can be given as to the liquidity
of the trading market for any such securities.
 
     Certain of the underwriters or agents and their associates may be customers
of, engage in transactions with or perform services for the Company in the
ordinary course of business.
 
                                 LEGAL OPINIONS
 
     The validity of the Securities is being passed upon for the Company by
Orrick, Herrington & Sutcliffe LLP, San Francisco, California.
 
                                    EXPERTS
