                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION INCLUDED IN THIS PROSPECTUS, THE
FOLLOWING RISK FACTORS SHOULD BE CAREFULLY CONSIDERED IN EVALUATING AN
INVESTMENT IN THE NOTES OFFERED HEREBY AND THE SHARES OF COMMON STOCK ISSUABLE
UPON CONVERSION THEREOF. THIS PROSPECTUS CONTAINS CERTAIN FORWARD-LOOKING
STATEMENTS WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT AND SECTION
21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED (THE "EXCHANGE ACT"),
WHICH INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS MAY DIFFER
SIGNIFICANTLY FROM THE RESULTS DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.
FACTORS THAT MIGHT CAUSE SUCH A DIFFERENCE INCLUDE, BUT ARE NOT LIMITED TO,
THOSE DISCUSSED IN THIS SECTION.
 
MANUFACTURING RISKS
 
    Currently, all of the Company's microprocessors are manufactured by
International Business Machine Corporation's Microelectronics Division ("IBM").
Any disruption in the supply of microprocessors from IBM would have a material
adverse effect on the Company's business and results of operations. There are
several material risks to which the Company is exposed by its reliance on IBM as
its sole source of supply for its only product family. Among these risks are the
possible unavailability of or delays in obtaining access to certain process
technologies, the absence of controllable product delivery schedules, potential
inability to achieve acceptable manufacturing yields and production costs and
the possible breakdown in the parties' relationship. In addition, if a favorable
result in pending litigation is appealed and reversed on appeal, IBM could be
held not to have been licensed by Intel to act as a semiconductor foundry for
the Company free of claims by Intel of patent infringement, which outcome could
affect IBM's willingness or obligation to continue to manufacture microprocessor
products for Cyrix. See "-- Litigation General; Microprocessor Litigation."
While IBM has committed to manufacture and sell to Cyrix specified volumes of
wafers of Cyrix-designed microprocessor products through December 31, 1999 (the
"IBM Product Agreement") and to manufacture and sell to Cyrix through December
1997 supplemental volumes of wafers of Cyrix-designed microprocessors (the "IBM
Foundry Agreement"), there is no assurance that delivered or contract volumes
will be sufficient to allow the Company to penetrate larger original equipment
manufacturer ("OEM") accounts, which require demonstrated capacity to deliver
significant volumes. The IBM Product Agreement obligates the Company to pay for
certain minimum quantities of microprocessor products regardless of whether the
Company places orders for microprocessors in such quantities, and the IBM
Foundry Agreement requires that the Company make rolling six-month forward
purchase commitments for microprocessors to be manufactured and sold to the
Company thereunder. These provisions could have a material adverse effect on the
Company's business and results of operations if the Company found itself for any
period of time without a microprocessor product that is competitive with the
leading microprocessors offered by the Company's competitors.
 
    Manufacture of the Company's current generation 6x86-TM- microprocessors
requires more advanced manufacturing processes than those required for the
Company's previous products. SGS Microelectronics ("SGS"), the other party with
which the Company has a manufacturing relationship, does not currently have the
appropriate combination of sophisticated manufacturing equipment and advanced
process technologies to manufacture the Company's 6x86 products with acceptable
performance and cost. Until SGS becomes capable of manufacturing the Company's
6x86 processors with acceptable performance and cost, the Company will obtain
most, if not all, of its microprocessors from IBM. As illustrated by the
Company's experience with SGS, each time the Company introduces a new product to
be manufactured using a new process technology there is a risk that problems
will be encountered in manufacturing the product. There can be no assurance that
third party manufacturers will consistently produce acceptable yields of
products in 1996 and beyond.
 
    The Company currently uses 0.65 micron, five-level metal complementary
metal-oxide semiconductor ("CMOS") processes for its 6x86 products. In the
second half of fiscal 1996, the Company will seek to employ 0.5 micron,
five-level metal CMOS processes for certain of its products to improve die size
and product performance. The Company believes that its primary competitors,
Intel Corporation
 
                                       3
<PAGE>
("Intel") and Advanced Micro Devices, Inc. ("AMD"), will use advanced 0.35
micron process technologies to manufacture microprocessors in 1996. Thus, Intel
and AMD may employ more advanced manufacturing processes than are available to
the Company from IBM and SGS in 1996, thereby potentially affording them
improved product performance and decreased manufacturing costs as compared to
the Company. See "-- Product Transitions; Dependence on Product Development" and
"-- Market Dominance by Intel."
 
    The Company frequently engages in discussions with third parties concerning
access to additional manufacturing capacity and advanced process technology, but
there can be no assurance that it will be able to secure access to such
additional capacity or process technology or to do so on terms the Company
considers desirable. Reliance on any new third party manufacturer would entail
the same risks as are described above relating to the Company's reliance on IBM
and SGS.
 
PRODUCT TRANSITIONS; DEPENDENCE ON PRODUCT DEVELOPMENT
 
    The microprocessor business is characterized by short product cycles,
intense price competition and rapid advances in product design and process
technology resulting in rapidly occurring product obsolescence. Next generation
microprocessor products are being introduced by the Company's competitors in
increasingly compressed time frames, thereby decreasing the product life cycles
of earlier generation microprocessors and placing additional pressure on
microprocessor companies to design and commence manufacturing next generation
products in a timely manner. The ability of the Company and its competitors to
introduce new products embodying improved performance characteristics and
competitive features and the emergence of new industry standards has rendered
and will continue to render existing products obsolete and unmarketable. As a
result, the Company must successfully develop and introduce on a timely basis
price-competitive microprocessor products that embody new features, meet
evolving industry standards and achieve levels of performance that are
acceptable to the market in order to be competitive. The only microprocessor
product the Company is currently producing for sale is its 6x86 microprocessor.
If the Company is unable to develop and successfully market in a timely manner
successor products with competitive performance, features and pricing, the
Company's business and operating results will be materially and adversely
affected.
 
    The industry's short product cycles also increase the risk that the Company
will from time to time find itself with excessive amounts of inventory of
products for which there is rapidly declining demand and significantly reduced
average selling prices. For example, in the fourth quarter of 1995, average
selling prices of 486DX2 microprocessors fell below the Company's cost to
purchase such products, the demand for these products declined substantially
compared to prior quarters and the Company wrote off substantially all of its
486 inventory, which exceeded $10 million. The requirement that the Company make
rolling six-month forward purchase commitments for products purchased from IBM
pursuant to the IBM Foundry Agreement heightens this risk. See "-- Manufacturing
Risks."
 
PRODUCT DELAYS
 
    The Company has in the past experienced delays in introducing certain of its
products. During 1995, the Company was not able to introduce and ramp production
of products with performance competitive with the leading performance processors
designed and manufactured by Intel. As a result, the Company's revenues and
profits declined significantly compared to prior periods. There can be no
assurance that the Company can successfully supply 6x86 products in adequate
commercial volumes with performance and cost characteristics comparable to
competitive products. There can be no assurance that the Company will not
encounter design, manufacturing process, manufacturing capacity or other
problems that could delay introduction of new products in the future. In
addition, the development of new products by the Company may require designing
around new or existing patents, resulting in lengthy delays or project
cancellations. If the Company is unable, for these or other reasons, to develop
and successfully market competitive products, in particular next generation
microprocessor products, in a timely manner, the Company's business and
operating results will be materially and adversely affected.
 
                                       4

MARKET DOMINANCE BY INTEL
 
    Intel currently has a dominant microprocessor market share, dictates the
performance standards required to compete in the microprocessor market and
influences product life cycles through frequent product introductions, product
enhancements and price competition. In addition to its dominant microprocessor
market share, Intel is also beginning to dominate the entire personal computer
platform. For example, Intel has obtained a dominant market share in sales of
64-bit or Pentium-class core logic chip sets and has emerged as one of the
world's largest motherboard manufacturers. In fiscal 1995, Intel purchased an
equity interest in Phoenix Technologies Ltd., one of the leading suppliers of
BIOS (basic input/output system) software, which translates signals from the
personal computer's operating system software to interface with the computer's
hardware devices. Further, Intel manufactures personal computers, incorporating
Intel microprocessors, chip sets, motherboards and other Intel-designed
components, for resale by OEMs under such OEMs' names.
 
    Intel's developments in semiconductor design and manufacturing processes
have allowed Intel to produce microprocessors that are smaller, faster and less
expensive to manufacture. These microprocessor cost and performance advantages,
coupled with Intel's financial strength, have enabled Intel to reduce prices on
its microprocessors within a short period of time following their introduction.
In addition, the Company believes that Intel has a strategy to maintain its
dominant market position through aggressive investments in manufacturing
capacity and research and development. According to reports filed by Intel with
the Commission, Intel spent during 1995 an estimated $1.3 billion on research
and development and $3.6 billion on property, plant and equipment, including
manufacturing facilities. In addition, the Company believes that Intel is
attempting to consolidate its dominant market position through an intensive
advertising campaign designed to strengthen brand loyalty to Intel by the
personal computer end-user. The Company does not have the financial resources to
compete with Intel on such a large scale. As long as Intel remains in this
dominant position, its product introduction schedule and pricing strategy may
have a material adverse effect on the Company's business, operating results and
financial condition.
 
COMPETITION AND MARKET ACCEPTANCE
 
    The markets for the Company's products are increasingly competitive. In
order to compete effectively in the market for high performance IBM compatible
microprocessors, the Company must develop and introduce on a timely basis
competitive products that embody new technology, meet evolving industry
standards and achieve levels of performance and price acceptable to the market.
See "-- Product Transitions; Dependence on Product Development" and "-- Product
Delays." In the recent past, Intel and other competitors have increased the
frequency of product introductions and enhancements and have used price
decreases to protect or improve their market share. The Company expects that
Intel and other competitors will continue to improve the performance of their
microprocessor products and use price decreases to protect or improve their
market share. There can be no assurance that the Company will be able to
successfully improve the performance of its microprocessors and its
manufacturing costs at the rates required to remain competitive with the leading
performance processors in the market or compete against price decreases, since
Intel and several of the Company's other competitors have substantially greater
financial, technical, manufacturing and marketing resources than the Company. In
order to be competitive, the Company must have sufficiently low costs so that it
can meet such price decreases and introduce products subject to less price
competition; however, there can be no assurance that the Company can accomplish
these goals and be price competitive.
 
    To compete with Intel at higher levels of integration as required by many
personal computer OEMs and dealers, Cyrix is dependent upon the infrastructure
of third-party designers and manufacturers of core logic chip sets,
motherboards, BIOS software, and other components of personal computers. As
Intel has become the dominant competitor in these segments of the personal
computer industry (see "-- Market Dominance by Intel"), third-party designers
and manufacturers of core logic chip sets, motherboards, BIOS software and other
components to support microprocessors have lost
 
                                       5
<PAGE>
market share to Intel, which owns the microprocessor designs and enjoys
significantly greater financial, technical, manufacturing and marketing
resources than such parties. Further, as Intel expanded its role in designing
and setting standards for personal computer systems, many personal computer OEMs
reduced their system development expenditures and now require processor
technologies to be provided at various levels of integration. In order to
compete with Intel and deliver the higher levels of integration required by many
OEMs and dealers in 1996 and beyond, the Company intends to form closer
relationships with third-party designers and manufacturers of core logic chip
sets, motherboards, BIOS software and other components, expand its chip set and
system design capabilities, and sell a portion of the Company's processors at
higher levels of integration incorporated into modules, boards and systems, but
there can be no assurance that the infrastructure which supports non-Intel
personal computer platforms will be competitive with Intel or continue to
support the Company's products.
 
    Other competitors in the IBM compatible microprocessor market include AMD,
IBM, SGS and Texas Instruments Incorporated ("TI"). Under a technology exchange
agreement and patent cross-license agreement between AMD and Intel, AMD has
historically competed in the microprocessor market with products which use
intellectual property developed by Intel. AMD recently acquired Nexgen, Inc.,
which has designed microprocessors which Nexgen claims were competitive with the
leading performance processors in the market. In recent years, IBM, SGS and TI
have entered the market using Cyrix's microprocessor designs. In addition, each
of these companies is in the process of designing IBM compatible
microprocessors. The Company may also face competition from manufacturers of
processors that are not currently IBM compatible, such as manufacturers of
IBM's, Motorola's and Apple's Power PC system processors. The Company believes
that other semiconductor manufacturers may enter the market, resulting in even
greater competition. Further, the rapid pace of technological change in the
industry means that companies other than Cyrix could develop a design or process
that radically advances microprocessor standards using a proprietary or
patent-protected design or process.
 
    OEMs generally select processors for inclusion in their personal computer
products based on the processors' price/performance characteristics and mix of
features. In addition, OEMs consider the ability of microprocessor vendors to
have access to advanced process technologies, introduce microprocessors
competitive with the leading processors in the market in a timely manner, supply
adequate volumes of processors which meet such vendors' performance requirements
in a timely and reliable manner, and be price competitive. Even after a Cyrix
product has been designed into an OEM's personal computer, a "design win," the
Company still faces competition to keep its products in the OEM's design.
Generally, an OEM can qualify a second source for any of the Company's products
because SGS and IBM each have licenses to manufacture certain Cyrix-designed
products. As the Company does not have exclusive rights to the products it
designs, revenue and gross margin for such products could be reduced.
 
    To date, the Company has been unable to sell significant quantities of its
microprocessors to most large OEMs such as Compaq, Hewlett Packard, Gateway
2000, Dell and Toshiba. During 1995 and the first quarter of 1996, AST Research
Inc. accounted for approximately 11% and 1%, respectively, of Cyrix's sales. As
the Company is currently transitioning its product offerings to higher
performance 6x86 processors, the Company must obtain design wins for its 6x86
processors with current or new OEM customers. There can be no assurance that the
Company will retain its current OEM customers during this product transition or
thereafter. The loss of such customers, if not replaced by other OEM customers
with similar sales volumes, could have a material adverse effect on the
Company's results of operations.
 
    In order to obtain manufacturing capacity, the Company has had to grant its
product rights to others, thereby creating additional competition, and may need
to do so again in order to obtain new manufacturing relationships or expand its
relationship with IBM or SGS.

INTELLECTUAL PROPERTY
 
    There are many patents held by Intel and other companies which relate to the
design and manufacture of semiconductor components, including microprocessors,
and computer systems. The Company is engaged in litigation with Intel regarding
alleged infringement by the Company of Intel's patents (see "-- Litigation"),
and from time to time has been notified that it may infringe the intellectual
property rights of others. Currently, the Company is a licensee of a limited
number of specified patents under an agreement with Intel and is not a licensee
under any patent license agreement with any other party. If the Company is
alleged to infringe one or more patents, it may seek a license to the patent.
However, there can be no assurance that a license will be available or available
on reasonable terms. In such event, the Company may be forced to litigate the
matter. If litigation were to commence, a license is not available on reasonable
terms or if any other third party is found to have a valid claim against the
Company, it could have a material adverse effect on the Company.
 
LITIGATION
 
    GENERAL; MICROPROCESSOR LITIGATION
 
    The processor industry is characterized by litigation involving patent and
infringement claims. Since March 1992, the Company and Intel have been engaged
in litigation related to certain of the Company's microprocessor products. For a
more complete discussion of the litigation with Intel, see Note 6 of the Notes
to Consolidated Financial Statements in the Company's Quarterly Report on Form
10-Q for the quarter ended June 30, 1996, which is incorporated herein by
reference. While the Company has received favorable judgments and rulings in
connection with such litigation, the Company believes that Intel has a strategy
of protecting its market share by filing intellectual property lawsuits against
its competitors, and that Intel may assert additional patent infringement claims
against the Company even though the Company has prevailed in all of the
remaining litigation with Intel referenced above. Potential additional Intel
litigation would likely involve different patents with new combination or system
claims. In addition, new patent applications are continually being filed, and
pending United States patent applications are confidential until patents are
issued. Thus, it is impossible to ascertain all potential patent infringement
claims. The damages and legal and other expenses of any such litigation could
materially and adversely affect the Company's future operating results. There
could be no assurance as to the outcome of any such litigation, and an adverse
decision could render the Company insolvent or severely impair the Company's
future business prospects.
 
    STOCKHOLDERS CLASS ACTION
 
    In December 1994, eleven class actions were filed in the United States
District Court for the Northern District of Texas, purportedly on behalf of
purchasers of the Company's Common Stock, alleging that the Company and various
of its officers and directors violated sections of the Exchange Act and Rule
10b-5 promulgated thereunder, by issuing false and misleading statements
concerning the introduction and production of the Company's Cx486DX2 40/80 MHZ
microprocessors. The complaints also allege that the conduct of the Company and
certain of its officers and directors constituted fraud and negligent
misrepresentation and that certain of such officers and directors sold shares of
Common Stock while in possession of material undisclosed information.
 
    In June 1995, all of the actions were consolidated into one complaint in the
federal district court in Dallas, Texas. The Company moved to dismiss the
consolidated amended class action complaint in July 1995. On August 20, 1996,
the Honorable A. Joe Fish, United States District Judge for the Northern
District of Texas, Dallas Division, entered a Memorandum Order dismissing
plaintiffs' complaint in this action. Judge Fish concluded that plaintiffs had
not met the heightened requirements of Federal Rule of Civil Procedure 9(b) for
pleading fraud-based federal securities law claims, and therefore plaintiffs'
complaint should be dismissed. Judge Fish, however, dismissed plaintiffs'
complaint without prejudice, and permitted plaintiffs leave to amend their
complaint to cure its deficiencies, if they are able to do so. Judge Fish
further required that plaintiffs file any such amendment by September 10, 1996.
The ultimate outcome of the stockholders class action cannot
 
                                       7
<PAGE>
presently be determined. A decision adverse to the Company in this matter could
have a material adverse effect on the Company, its financial condition, its
results of operations and its future prospects.
 
INTERNATIONAL OPERATIONS
 
    International sales represent a significant portion of the Company's net
product sales. Further, many of the motherboards, chip sets and other components
required to manufacture personal computers are manufactured outside of the
United States. If air transportation between the United States and the Company's
overseas suppliers or customers were disrupted, or shortages in the various
essential materials were to occur due to foreign political or economic factors,
there could be a material adverse effect on the Company's operations.
 
THE SEMICONDUCTOR AND PERSONAL COMPUTER INDUSTRIES
 
    The semiconductor industry has historically been characterized by wide
fluctuations in product supply and demand. A reduced rate of growth in the
demand for microprocessors could adversely affect the market for the Company's
products. From time to time, the personal computer and semiconductor industries
have also experienced significant downturns, often in connection with, or in
anticipation of, declines in general economic conditions. These downturns have
been characterized by diminished product demand, production overcapacity and
subsequent accelerated erosion of average selling prices. The Company's business
could be materially and adversely affected by industry-wide fluctuations in the
future.
 
    More recently, the personal computer industry has been consolidating as the
larger, more established manufacturers have become more price aggressive and
have been gaining market share at the expense of other domestic and
international manufacturers. The majority of Cyrix's customer base consists of
smaller personal computer manufacturers. The continued market share gains of the
larger manufacturers could have the effect of reducing demand for the Company's
products and may adversely affect its operating results.
 
DEPENDENCE ON KEY EMPLOYEES
 
    The Company's development, management of its growth and other activities
depend on the efforts of key management and technical employees, as well as its
directors. Competition to attract and retain such persons is intense. To attract
and retain well-qualified employees, the Company uses incentives such as
competitive compensation, stock options, an employee stock purchase plan and a
profit sharing plan. The Company's future success is also dependent upon its
ability to effectively attract, retain, train, motivate and manage its
employees, including its key management and technical personnel. The Company
from time to time experiences difficulty in meeting its internal hiring targets
with respect to technical personnel, and there can be no assurance that the
Company will continue to be able to attract and retain key management and
technical personnel in the future. Failure to do so could have a material
adverse effect on the Company's business and operating results. The Company's
future success is also dependent upon its ability to effectively attract, retain
and motivate qualified persons to serve as directors, and there can be no
assurance that the Company will be able to do so.
 
ABSENCE OF TRADING MARKET; TRANSFER RESTRICTIONS
 
    There is no existing trading market for the Notes and there can be no
assurance as to the liquidity of any such market that may develop, the ability
of the holders of Notes to sell such securities, the price at which the holders
of Notes would be able to sell such securities or whether a trading market, if
it develops, will continue. If such a market were to exist, the Notes could
trade at prices higher or lower than their principal amount, depending on many
factors, including prevailing interest rates, the market for similar securities
and the operating results of the Company. Each purchaser of Notes offered hereby
in making its purchase will be deemed to have made certain acknowledgments,
representations and agreements. Transfers of Notes and Common Stock issuable
upon conversion of the Notes are subject to certain restrictions.
 
                                       8
<PAGE>
QUARTERLY FLUCTUATIONS; STOCK PRICE VOLATILITY
 
    The Company anticipates that its quarterly operating results will fluctuate
as a result of the number and timing of new product introductions, product
shipments, product returns, marketing expenditures, research and development
expenditures and promotional programs. The trading price of the Common Stock has
been and may continue to be subject to wide fluctuations in response to
quarter-to-quarter variations in operating results, changes in earnings
estimates by analysts, announcements concerning new products, strategic
relationships or technological innovations by the Company or its competitors,
general conditions in the computer industry and other events or facts. In recent
years the stock market in general, and the shares of technology companies in
particular, have experienced extreme price fluctuations. This volatility has had
a substantial effect on the market prices of securities issued by many companies
for reasons unrelated to their operating performance. These broad market
fluctuations may adversely affect the market price of the Common Stock.
 
FACTORS INHIBITING TAKEOVER
 
    The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, which imposes certain restrictions on the ability of a
third party to effect an unsolicited change in control of the Company. In
addition, the Company's Restated Certificate of Incorporation, as amended, does
not provide for cumulative voting in the election of directors and includes
provisions which authorize the Board of Directors to establish the designations,
preferences, rights and powers of series of preferred stock without any vote by
the stockholders. The establishment of any such series and issuance of shares of
such series may have the effect of delaying or preventing changes in control or
management of the Company. These restrictions could adversely affect the market
price of the Company's Common Stock.
 
                              RECENT DEVELOPMENTS
 
    In the first quarter of fiscal 1996, the Company began to receive volume
production of its 6x86 microprocessors which provide system-level performance
competitive with Intel's Pentium microprocessors. Competitive pressures resulted
in lower than anticipated unit sales and significant declines in average selling
prices of the Company's 6x86 microprocessors during the second quarter of fiscal
1996. The Company reported revenues of $27.1 million and a net loss of $16.4
million for the quarter ended June 30, 1996, compared with revenues of $50.2
million and net income of $7.5 million for the second quarter of fiscal 1995.
The Company began selling computer systems during the second quarter of 1996;
revenue from the sale of computer systems accounted for less than 10% of the
Company's net product sales for the quarter ended June 30, 1996. For additional
information regarding operating results, financial condition and factors
affecting the results of future periods, see the information incorporated by
reference herein and the risk factors included in this document.

    Conversion Rate (as defined herein) and the number of shares of Common Stock
    issuable upon conversion of the Notes are subject to adjustment under
    certain circumstances. See "Description of Notes -- Conversion Rights."
    Accordingly, the number of shares of Common Stock issuable upon conversion
    of the Notes may increase or decrease from time to time.
 
(2) Assumes conversion into Common Stock of the full amount of Notes held by the
    Selling Securityholder at the initial conversion rate and the offering of
    such shares by such Selling Securityholder pursuant to the Registration
    Statement of which this Prospectus forms a part. The Conversion Rate and the
    number of shares of Common Stock issuable upon conversion of the Notes is
    subject to adjustment under certain circumstances. See "Description of Notes
    -- Conversion Rights." Accordingly, the number of shares of Common Stock
    issuable upon conversion of the Notes may increase or decrease from time to

                              DESCRIPTION OF NOTES
 
    The Notes are issued under an Indenture, dated as of May 28, 1996 (the
"Indenture"), between the Company and Bank of Montreal Trust Company, as Trustee
(the "Trustee"), copies of which will be available for inspection at the
Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of
New York. Wherever particular defined terms of the Indenture (including the
Notes and the various forms thereof) are referred to, such defined terms are
incorporated herein by reference (the Notes and various terms relating to the
Notes being referred to in the Indenture as "Securities"). References in this
section to the "Company" are solely to Cyrix Corporation and not its
subsidiaries. The following summaries of certain provisions of the Indenture do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, the detailed provisions of the Notes and the
Indenture, including the definitions therein of certain terms. Section
references below are to Sections of the Indenture.
 
GENERAL
 
    The Notes are unsecured subordinated obligations of the Company, are limited
to U.S.$110,000,000 aggregate principal amount (plus an additional U.S.
$16,500,000 aggregate principal amount to cover over-allotments) and will mature
on June 1, 2001 and be payable at a price of 100% of the principal amount
thereof. The Notes will bear interest at the rate per annum shown on the front
cover of this Prospectus from May 28, 1996, payable semiannually on June 1 and
December 1 of each year, commencing on December 1, 1996. Interest payable per
$1,000 principal amount of Notes for the period from May 28, 1996 to December 1,
1996 will be U.S.$27.9583. (SectionSection 3.1 and 3.7)
 
    The Notes will be convertible into Common Stock initially at the conversion
rate stated on the cover page hereof, subject to adjustment upon the occurrence
of certain events described under "-- Conversion Rights," at any time on or
after the 90th day following the last original issue date of the Notes and prior
to the close of business on the maturity date, unless previously redeemed or
repurchased. (Section 12.1)
 
    The Notes are redeemable at the option of the Company, on or after June 1,
1999, in whole or in part, at the redemption prices set forth below under "--
Redemption," plus accrued interest to the redemption date. (Section 2.2)
 
FORM AND DENOMINATION
 
    Regulation S Notes will initially be represented by one or more global Notes
in fully registered form (collectively, the "Regulation S Global Note") without
interest coupons registered in the name of a nominee of The Depository Trust
Company ("DTC") and deposited with the Trustee, for the accounts of Cedel Bank,
Societe Anonyme ("CEDEL") and for Morgan Guaranty Trust Company of New York,
Brussels Office, as operator of Euroclear, on the date of payment for and
delivery of such Notes (the "Settlement Date"), which occurred on May 28, 1996.
Upon deposit of the Regulation S Global Note, CEDEL or Euroclear, as
appropriate, credited each subscriber with a principal amount of Notes equal to
the principal amount thereof for which it had subscribed and paid. Until the
40th day (such date, the "Exchange Date") after the later of the commencement of
the offering of the Notes and the last original issue date of the Notes (such
period, the "Restricted Period"), beneficial interests in the Regulation S
Global Note were held only through Euroclear or CEDEL, unless delivery was made
through the Restricted Global Note (as defined) in accordance with the
certification requirements described below.
 
    Rule 144A Notes initially were represented by one or more global Notes in
fully registered form without interest coupons (collectively, the "Restricted
Global Note" and, together with the Regulation S Global Note, the "Registered
Global Notes"). Rule 144A Notes are issued in minimum denominations of $1,000
and integral multiples thereof. The Restricted Global Note was deposited with
the Trustee as custodian for DTC and registered in the name of a nominee of DTC.
Beneficial interests in the Restricted Global Note may not be exchanged for
beneficial interests in the Regulation S Global
 
                                       12
<PAGE>
Note at any time except in the limited circumstances described below. See "--
Transfer, Exchange and Withdrawal Exchanges between the Regulation S Global Note
and the Restricted Global Note." (Articles Two and Three)
 
    Owners of beneficial interests in any Registered Global Note will hold such
interests pursuant to the procedures and practices of DTC and must exercise any
rights in respect of their interests (including any right to convert, exchange
or require repurchase of their interests) in accordance with those procedures
and practices. Such beneficial owners will not be Holders, and will not be
entitled to any rights under any Note or the Indenture, with respect to any
Registered Global Note, and the Company and the Trustee, and any of their
respective agents, may treat DTC as the Holder and owner of any Registered
Global Note. See "-- Depository Procedures with Respect to Registered Global
Notes."
 
    Except as set forth below, the Registered Global Notes may be transferred,
in whole and not in part, only to another nominee of DTC or to a successor of
DTC or its nominee. Beneficial interests in the Registered Global Notes may not
be exchanged for Notes in certificated form except in the limited circumstances
described below. See "-- Transfer, Exchange and Withdrawal -- Exchange of
Interests in Registered Global Notes for Registered Certificated Notes." The
Notes are not issuable in bearer form.
 
    Rule 144A Notes (including beneficial interests in the Restricted Global
Note) will be subject to certain restrictions on transfer and bear a restrictive
legend. The Regulation S Global Note will be subject to restrictions on resale
and bears a legend regarding those restrictions, as provided in the Indenture.
In addition, transfer of beneficial interests in the Registered Global Notes
will be subject to the applicable rules and procedures of DTC and its
Participants or Indirect Participants (including, if applicable, those of
Euroclear and CEDEL), which may change from time to time.
 
    For a description of the depository procedures with respect to the
Registered Global Notes, see "-- Depository Procedures with Respect to
Registered Global Notes."
 
CONVERSION RIGHTS
 
    The Holder of any Note will have the right, at the Holder's option, to
convert any portion of the principal amount of any Note that is an integral
multiple of $1,000 into shares of Common Stock at any time on or after the 90th
day following the last original issue date of the Notes and prior to the close
of business on the maturity date, unless previously redeemed or repurchased, at
a conversion rate of 25.1572 shares of Common Stock per $1,000 principal amount
of Notes (the "Conversion Rate") (equivalent to a conversion price of $39.75 per
share of Common Stock), subject to adjustment as described below. The right to
convert a Note called for redemption or delivered for repurchase will terminate
at the close of business on the Redemption Date for such Note or the Repurchase
Date, as the case may be. (Section 12.1)
 
    The right of conversion attaching to any Note may be exercised by the Holder
by delivering the Note at the Corporate Trust Office of the Trustee in the
Borough of Manhattan, The City of New York, accompanied by a duly signed and
completed notice of conversion. Such notice of conversion can be obtained at the
office of the Trustee at its Corporate Trust Offices in New York City. The
conversion date will be the date on which the Note and the duly signed and
completed notice of conversion are so delivered. As promptly as practicable on
or after the conversion date, the Company will issue and deliver to the Trustee
a certificate or certificates for the number of full shares of Common Stock
issuable upon conversion, together with payment in lieu of any fraction of a
share; such certificate will be sent by the Trustee to the Conversion Agent for
delivery to the Holder. Such shares of Common Stock issuable upon conversion of
the Notes, in accordance with the provisions of the Indenture, will be fully
paid and nonassessable and will rank PARI PASSU with the other shares of Common
Stock of the Company outstanding from time to time. Any Note surrendered for
conversion during the period from the close of business on any Regular Record
Date to the opening of business on the next succeeding Interest Payment Date
(except Notes (or portions thereof) called for redemption on a Redemption
 
                                       13
<PAGE>
Date or repurchaseable on a Repurchase Date occurring, in either case, within
such period) must be accompanied by payment of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of Notes being
surrendered for conversion. The interest payable on such Interest Payment Date
with respect to any Note (or portion thereof, if applicable) which has been
called for redemption on a Redemption Date, or is repurchaseable on a Repurchase
Date, occurring, in either case, during the period referred to in the
parenthetical in the immediately preceding sentence, which Note (or portion
thereof, if applicable) is surrendered for conversion during such period, shall
be paid to the Holder of such Note being converted in an amount equal to the
interest that would have been payable on such Note if such Note had been
converted as of the close of business on such Interest Payment Date. The
interest payable on such Interest Payment Date in respect of any Note (or
portion thereof, as the case may be) which has not been called for redemption on
a Redemption Date, or is not eligible for repurchase on a Repurchase Date,
occurring, in either case, during such period, which Note (or portion thereof,
as the case may be) is surrendered for conversion during such period, shall be
paid to the Holder of such Note as of such Regular Record Date. Interest payable
in respect of any Note surrendered for conversion on or after an Interest
Payment Date shall be paid to the Holder of such Note as of the next preceding
Regular Record Date, notwithstanding the exercise of the right of conversion. As
a result of the foregoing provisions, except as provided above, Holders that
surrender Notes for conversion on a date that is not an Interest Payment Date
will not receive any interest for the period from the Interest Payment Date next
preceding the date of conversion to the date of conversion or for any later
period, even if the Notes are surrendered after a notice of redemption (except
for the payment of interest on Notes called for redemption on a Redemption Date
or repurchaseable on a Repurchase Date between a Regular Record Date and the
Interest Payment Date to which it relates, as provided above). No other payment
or adjustment for interest, or for any dividends in respect of Common Stock,
will be made upon conversion. Holders of Common Stock issued upon conversion
will not be entitled to receive any dividends payable to holders of Common Stock
as of any record time or date before the close of business on the conversion
date. No fractional shares will be issued upon conversion but, in lieu thereof,
an appropriate amount will be paid in cash by the Company based on the market
bid price of Common Stock at the close of business on the day of conversion.
(SectionSection 2.2, 3.7, 12.2 and 12.3)
 
    A Holder delivering a Note for conversion will not be required to pay any
taxes or duties in respect of the issue or delivery of Common Stock on
conversion but will be required to pay any tax or duty which may be payable in
respect of any transfer involved in the issue or delivery of the Common Stock in
a name other than that of the Holder of the Note. Certificates representing
shares of Common Stock will not be issued or delivered unless all taxes and
duties, if any, payable by the Holder have been paid. (Section 2.8)
 
    The Conversion Rate is subject to adjustment in certain events, including,
without duplication: (a) dividends (and other distributions) payable in Common
Stock, (b) the issuance to all holders of Common Stock of rights, options or
warrants entitling them to subscribe for or purchase Common Stock at less than
the then Current Market Price of such Common Stock (determined as provided in
the Indenture) as of the record date for shareholders entitled to receive such
rights, options or warrants, (c) subdivisions, combinations and
reclassifications of Common Stock, (d) distributions to all holders of Common
Stock of evidences of indebtedness of the Company, shares of capital stock, cash
or assets (including securities, but excluding those dividends, rights, options,
warrants and distributions referred to above, dividends and distributions paid
exclusively in cash and in mergers and consolidations to which the next
succeeding paragraph applies), (e) distributions consisting exclusively of cash
(excluding any cash portion of distributions referred to in (d) above, or cash
distributed upon a merger or consolidation to which the next succeeding
paragraph applies) to all holders of Common Stock in an aggregate amount that,
combined together with (i) other such all-cash distributions made within the
preceding 12 months in respect of which no adjustment has been made and (ii) any
cash and the fair market value of other consideration payable in respect of any
tender offer (including the type described in (f) below) by the Company or any
of its subsidiaries for Common Stock concluded within the preceding 12 months in
respect of which no adjustment has been made, exceeds
 
                                       14
<PAGE>
10% of the Company's market capitalization (being the product of the Current
Market Price per share of the Common Stock on the record date for such
distribution times the number of shares of Common Stock outstanding) on such
date, and (f) the successful completion of a tender offer made by the Company or
any of its subsidiaries for Common Stock which involves an aggregate
consideration that, together with (i) any cash and other consideration payable
in a tender offer by the Company or any of its subsidiaries for Common Stock
expiring within the 12 months preceding the expiration of such tender offer in
respect of which no adjustment has been made and (ii) the aggregate amount of
any such all-cash distributions referred to in (e) above to all holders of
Common Stock within the 12 months preceding the expiration of such tender offer
in respect of which no adjustments have been made, exceeds 10% of the Company's
market capitalization on the expiration of such tender offer. The Company
reserves the right to make such reductions in the Conversion Rate in addition to
those required in the foregoing provisions as it considers to be advisable in
order that any event treated for United States federal income tax purposes as a
dividend of stock or stock rights will not be taxable to the recipients. No
adjustment of the Conversion Rate will be required to be made until the
cumulative adjustments amount to 1.0% or more of the Conversion Rate. (Section
12.4) The Company will compute any adjustments to the Conversion Rate pursuant
to this paragraph and will give notice by mail to Holders of the Registered
Notes of any adjustments. (Section 12.5)
 
    In case of any consolidation or merger of the Company with or into another
Person or any merger of another Person into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or
cancellation of the Common Stock), or in case of any sale or transfer of all or
substantially all of the assets of the Company, each Note then outstanding will,
without the consent of the Holder of any Note, become convertible only into the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Common Stock into which such Note was convertible immediately prior thereto
(assuming such holder of Common Stock failed to exercise any rights of election
and that such Note was then convertible). (Section 12.11)
 
    If at any time the Company makes a distribution of property to its
stockholders which would be taxable to such stockholders as a dividend for
United States federal income tax purposes (E.G., distributions of evidences of
indebtedness or assets of the Company, but generally not stock dividends on
Common Stock or rights to subscribe for Common Stock) and, pursuant to the
anti-dilution provisions of the Indenture, the number of shares into which Notes
are convertible is increased, such increase may be deemed for federal income tax
purposes to be the payment of a taxable dividend to Holders of Notes.
 
SUBORDINATION
 
    The payment of the principal of, premium, if any, and interest on the Notes
(including any Liquidated Damages (as defined) and any amounts payable upon the
redemption or the repurchase of the Notes permitted by the Indenture) will be
subordinated in right of payment to the extent set forth in the Indenture to the
prior payment in full of the principal of, premium, if any, interest and other
amounts in respect of all Senior Indebtedness of the Company. The principal
amount of outstanding Senior Indebtedness was approximately $15.8 million at
June 30, 1996. A substantial portion of the Company's Senior Indebtedness is
secured by a lien on substantially all the Company's assets, including a lien on
all or a portion of the outstanding shares of capital stock of certain of the
Company's subsidiaries.
 
    "Senior Indebtedness" is defined in the Indenture to mean: the principal of
(and premium, if any) and interest (including all interest accruing subsequent
to the commencement of any bankruptcy or similar proceeding, whether or not a
claim for post-petition interest is allowable as a claim in any such proceeding)
on, and all fees and other amounts payable in connection with, the following,
whether absolute or contingent, secured or unsecured, due or to become due,
outstanding on the date of the Indenture or thereafter created, incurred or
assumed: (a) indebtedness of the Company evidenced by credit or loan agreements,
notes, bonds, debentures, or other written obligations, (b) all obligations of
 
                                       15
<PAGE>
the Company for money borrowed, (c) all obligations of the Company evidenced by
a note or similar instrument given in connection with the acquisition of any
businesses, properties or assets of any kind, (d) obligations of the Company as
lessee under leases required to be capitalized on the balance sheet of the
lessee under generally accepted accounting principles and leases for capital
equipment, whether or not capitalized, including, without limitation,
obligations of the Company under the Master Lease Finance Agreement, dated March
31, 1992, between the Company and BancBoston Leasing, Inc., (e) obligations of
the Company under interest rate and currency swaps, caps, floors, collars, hedge
agreements, forward contracts, or similar agreements or arrangements intended to
protect the Company against fluctuations in interest or currency exchange rates
or commodity prices, (f) all reimbursement obligations of the Company with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of the Company, (g) all obligations of the Company issued or
assumed as the deferred purchase price of property or services (but excluding
trade accounts payable or accrued liabilities arising in the ordinary course of
business), (h) all obligations of the type referred to in clauses (a) through
(g) above of another Person and all dividends of another Person, the payment of
which, in either case, the Company has assumed or guaranteed, or for which the
Company is responsible or liable, directly or indirectly, jointly or severally,
as obligor, guarantor or otherwise, or which is secured by a lien on property of
the Company, and (i) renewals, extensions, modifications, replacements,
restatements and refundings of, or any indebtedness or obligation issued in
exchange for, any such indebtedness or obligation described in clauses (a)
through (h) of this paragraph; provided, however, that Senior Indebtedness shall
not include the Securities or any such indebtedness or obligation if the terms
of such indebtedness or obligation (or the terms of the instrument under which,
or pursuant to which it is issued) provides that such indebtedness or obligation
is not superior in right of payment to the Securities.
 
    No payment on account of principal of, premium, if any, or interest on the
Notes (including any Liquidated Damages (as defined) and any amounts payable
upon the redemption or the repurchase of the Notes permitted by the Indenture)
may be made by the Company if there is a default in the payment of principal,
premium, if any, or interest (including a default under any repurchase or
redemption obligation) or other amounts with respect to any Senior Indebtedness
or if any other event of default with respect to any Senior Indebtedness,
permitting the holders thereof to accelerate the maturity thereof, shall have
occurred and shall not have been cured or waived or shall not have ceased to
exist after written notice to the Company and the Trustee by any holder of
Senior Indebtedness. Upon any acceleration of the principal due on the Notes or
payment or distribution of assets of the Company to creditors upon any
dissolution, winding up, liquidation or reorganization, whether voluntary or
involuntary, marshaling of assets, assignment for the benefit of creditors, or
in bankruptcy, insolvency, receivership or other similar proceedings of the
Company, all principal, premium, if any, and interest or other amounts due on
all Senior Indebtedness must be paid in full before the Holders of the Notes are
entitled to receive any payment. By reason of such subordination, in the event
of insolvency, creditors of the Company who are holders of Senior Indebtedness
may recover more, ratably, than the Holders of the Notes, and such subordination
may result in a reduction or elimination of payments to the Holders of the
Notes. (Section 13.3)
 
    In addition, the Notes will be structurally subordinated to all indebtedness
and other liabilities (including trade payables and lease obligations) of the
Company's subsidiaries, as any right of the Company to receive any assets of its
subsidiaries upon their liquidation or reorganization (and the consequent right
of the Holders of the Notes to participate in those assets) will be effectively
subordinated to the claims of that subsidiary's creditors (including trade
creditors), except to the extent that the Company itself is recognized as a
creditor of such subsidiary, in which case the claims of the Company would still
be subordinate to any security interest in the assets of such subsidiary and any
indebtedness of such subsidiary senior to that held by the Company. As of June
30, 1996, there was outstanding approximately $1.4 million of indebtedness of
subsidiaries of the Company (excluding intercompany indebtedness); this amount
has been guaranteed by the Company and is included in the principal amount of
the Company's outstanding Senior Indebtedness at June 30, 1996, as set forth
above.
 
                                       16
<PAGE>
    The Indenture does not limit the Company's or its subsidiaries' ability to
incur Senior Indebtedness or any other indebtedness.
 
REDEMPTION
 
    The Notes may not be redeemed at the option of the Company prior to June 1,
1999. On and after June 1, 1999, the Notes may be redeemed, in whole or in part,
at the option of the Company, at the redemption prices specified below, upon not
less than 30 nor more than 60 days' prior notice as provided under "-- Notices"
below.
 
    The redemption price (expressed as a percentage of principal amount) is as
follows for the 12-month periods beginning on June 1 of the following years:

and thereafter is equal to 100% of the principal amount, in each case together
with accrued interest to the date of redemption. (SectionSection 2.2, 11.1,
11.5, 11.7)
 
    No sinking fund is provided for the Notes.
 
PAYMENT AND CONVERSION
 
    The principal of Notes will be payable in U.S. dollars, against surrender
thereof at the Corporate Trust Office of the Trustee in the Borough of
Manhattan, The City of New York, by dollar check drawn on, or by transfer to a
dollar account (such transfer to be made only to Holders of an aggregate
principal amount of Notes in excess of U.S. $2,000,000) maintained by the Holder
with, a bank in New York City. Payment of any installment of interest on Notes
will be made to the Person in whose name such Notes (or any predecessor Note) is
registered at the close of business on the May 15 or the November 15 (whether or
not a Business Day) immediately preceding the relevant Interest Payment Date (a
"Regular Record Date"). Payments of such interest will be made by a dollar check
drawn on a bank in New York City mailed to the Holder at such Holder's
registered address or, upon application by the Holder thereof to the Trustee not
later than the applicable Regular Record Date, by transfer to a dollar account
(such transfer to be made only to Holders of an aggregate principal amount of
Notes in excess of U.S $2,000,000) maintained by the Holder with a bank in New
York City. No transfer to a dollar account will be made unless the Trustee has
received written wire instructions not less than 15 days prior to the relevant
payment date. (Section 2.2)
 
    Payments in respect of the principal of (and premium, if any) and interest
on any Registered Global Note registered in the name of DTC or its nominee will
be payable by the Trustee to DTC or its nominee in its capacity as the
registered Holder under the Indenture. Under the terms of the Indenture, the
Company and the Trustee will treat the Persons in whose names the Notes,
including the Registered Global Notes, are registered as the owners thereof for
the purpose of receiving such payments and for any and all other purposes
whatsoever. Consequently, neither the Company, the Trustee nor any agent of the
Company or the Trustee has or will have any responsibility or liability for (i)
any aspect of DTC's records or any Participant's or Indirect Participant's
records relating to or payments made on account of beneficial ownership
interests in the Registered Global Notes, or for maintaining, supervising or
reviewing any of DTC's records or any Participant's or Indirect Participant's
records relating to the beneficial ownership interests in the Registered Global
Notes, or (ii) any other matter relating to the actions and practices of DTC or
any of its Participants or Indirect Participants.
 
    Any payment on the Notes due on any day which is not a Business Day need not
be made on such day, but may be made on the next succeeding Business Day with
the same force and effect as if made on such due date, and no interest shall
accrue on such payment for the period from and after such date. "Business Day,"
when used with respect to any place of payment, place of conversion or any other
place, as the case may be, means each Monday, Tuesday, Wednesday, Thursday and
Friday which is not
 
                                       17
<PAGE>
a day on which banking institutions in such place of payment, place of
conversion or other place, as the case may be, are authorized or obligated by
law or executive order to close; provided, however, that a day on which banking
institutions in New York, New York or London, England are authorized or
obligated by law or executive order to close shall not be a Business Day for
certain purposes. (Section 1.1 and 2.2)
 
    Notes may be surrendered for conversion at the Corporate Trust Office of the
Trustee in the Borough of Manhattan, The City of New York. Notes surrendered for
conversion must be accompanied by appropriate notices and any payments in
respect of interest or taxes, as applicable, as described above under "--
Conversion Rights." (Section 2.2 and 12.2)
 
    The Company has initially appointed the Trustee as Paying Agent and
Conversion Agent. The Company may at any time terminate the appointment of any
Paying Agent or Conversion Agent and appoint additional or other Paying Agents
and Conversion Agents, provided that until the Notes have been delivered to the
Trustee for cancellation, or moneys sufficient to pay the principal of, premium,
if any, and interest on the Notes have been made available for payment and
either paid or returned to the Company as provided in the Indenture, it will
maintain an office or agency in the Borough of Manhattan, The City of New York
for surrender of Notes for conversion. Notice of any such termination or
appointment and of any change in the office through which any Paying Agent or
Conversion Agent will act will be given in accordance with "-- Notices" below.
(Section 10.2)
 
    All moneys deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of principal of, premium, if any, or
interest on any Notes which remain unclaimed at the end of two years after such
payment has become due and payable will be repaid to the Company, and the Holder
of such Note will thereafter look only to the Company for payment thereof.
(Section 10.3)
 
REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE IN CONTROL
 
    If a Change in Control (as defined) occurs, each Holder of Notes shall have
the right, at the Holder's option, to require the Company to repurchase all of
such Holder's Notes not theretofore called for redemption, or any portion of the
principal amount thereof, that is $5,000 or an integral multiple of $1,000 in
excess thereof, on the date (the "Repurchase Date") that is 45 days after the
date of the Company Notice (as defined), at a price equal to 100% of the
principal amount of the Notes to be repurchased, together with interest accrued
to the Repurchase Date (the "Repurchase Price"). (Section 14.1)
 
    The Company may, at its option, in lieu of paying the Repurchase Price in
cash, pay the Repurchase Price in Common Stock valued at 95% of the average of
the closing bid prices of the Common Stock for the five trading days immediately
preceding the second day prior to the Repurchase Date; provided that payment may
not be made in Common Stock unless the Company satisfies certain conditions with
respect to such payment prior to the Repurchase Date as provided in the
Indenture. (SectionSection 14.1 and 14.2)
 
    Within 30 days after the occurrence of a Change in Control, the Company is
obligated to give to all Holders of the Notes notice, as provided in the
Indenture (the "Company Notice"), of the occurrence of such Change in Control
and of the repurchase right arising as a result thereof. The Company must also
deliver a copy of the Company Notice to the Trustee. To exercise the repurchase
right, a Holder of Notes must deliver on or before the 30th day after the date
of the Company Notice irrevocable written notice to the Trustee of the Holder's
exercise of such right, together with the Notes with respect to which the right
is being exercised. (Section 14.3)
 
    A "Change in Control" shall be deemed to have occurred at such time after
the original issuance of the Notes as there shall occur:
 
        (i) the acquisition by any Person (including any syndicate or group
    deemed to be a "person" under Section 13(d)(3) of the Exchange Act) of
    beneficial ownership, directly or indirectly, through a purchase, merger or
    other acquisition transaction or series of transactions, of shares of
 
                                       18
<PAGE>
    capital stock of the Company entitling such Person to exercise 50% or more
    of the total voting power of all shares of capital stock of the Company
    entitled to vote generally in elections of directors, other than any such
    acquisition by the Company, any subsidiary of the Company or any employee
    benefit plan of the Company; or
 
        (ii) any consolidation or merger of the Company with or into, any other
    Person, any merger of another Person into the Company, or any conveyance,
    sale, transfer or lease of all or substantially all of the assets of the
    Company to another Person (other than (a) any such transaction (x) which
    does not result in any reclassification, conversion, exchange or
    cancellation of outstanding shares of capital stock of the Company and (y)
    pursuant to which the holders of the Common Stock immediately prior to such
    transaction have the entitlement to exercise, directly or indirectly, 50% or
    more of the total voting power of all shares of capital stock entitled to
    vote generally in the election of directors of the continuing or surviving
    corporation immediately after such transaction and (b) any merger which is
    effected solely to change the jurisdiction of incorporation of the Company
    and results in a reclassification, conversion or exchange of outstanding
    shares of Common Stock into solely shares of common stock);
 
provided, however, that a Change in Control shall not be deemed to have occurred
if the closing bid price per share of the Common Stock for any five trading days
within the period of 10 consecutive trading days ending immediately after the
later of the Change in Control or the public announcement of the Change in
Control (in the case of a Change in Control under clause (i) above) or the
period of 10 consecutive trading days ending immediately before the Change in
Control (in the case of a Change in Control under clause (ii) above) shall equal
or exceed 105% of the Conversion Price of the Notes in effect on each such
trading day. The "Conversion Price" is equal to $1,000 divided by the Conversion
Rate. "Beneficial Owner" shall be determined in accordance with Rule 13d-3
promulgated by the Commission under the Exchange Act, as in effect on the date
of execution of the Indenture. "Person" includes any syndicate or group which
would be deemed to be a "person" under section 13(d)(3) of the Exchange Act.
(Section 14.4)
 
    Rule 13e-4 under the Exchange Act requires the dissemination of certain
information to security holders in the event of an issuer tender offer and may
apply in the event that the repurchase option becomes available to Holders of
the Notes. The Company will comply with this rule to the extent applicable at
that time.
 
    The Company may, to the extent permitted by applicable law, at any time
purchase Notes in the open market or by tender at any price or by private
agreement. Any Note so purchased by the Company may, to the extent permitted by
applicable law and subject to restrictions contained in the Underwriting
Agreement, be re-issued or resold or may, at the Company's option, be
surrendered to the Trustee for cancellation. Any Notes surrendered as aforesaid
may not be re-issued or resold and will be canceled promptly.
 
    The foregoing provisions would not necessarily afford Holders of the Notes
protection in the event of highly leveraged or other transactions involving the
Company that may adversely affect Holders.
 
MERGERS AND SALES OF ASSETS BY THE COMPANY
 
    The Company may not consolidate with or merge into any other Person or
convey, transfer, sell or lease its properties and assets substantially as an
entirety to any Person, and the Company shall not permit any Person to
consolidate with or merge into the Company or convey, transfer, sell or lease
such Person's properties and assets substantially as an entirety to the Company
unless (a) the Person formed by such consolidation or into or with which the
Company is merged or the Person to which the properties and assets of the
Company are so conveyed, transferred, sold or leased shall be a corporation,
limited liability company, partnership or trust organized and existing under the
laws of the United States, any State thereof or the District of Columbia and, if
other than the Company, shall expressly assume the payment of the principal of,
premium, if any, and interest on the Notes and the
 
                                       19
<PAGE>
performance of the other covenants of the Company under the Indenture, and (b)
immediately after giving effect to such transaction, no Event of Default, and no
event that, after notice or lapse of time or both, would become an Event of
Default, shall have occurred and be continuing. (Section 7.1)
 
EVENTS OF DEFAULT
 
    The following will be Events of Default under the Indenture: (a) failure to
pay principal of or premium, if any, on any Note when due, whether or not such
payment is prohibited by the subordination provisions of the Notes and the
Indenture; (b) failure to pay any interest (including any Liquidated Damages) on
any Note when due, continuing for 30 days, whether or not such payment is
prohibited by the subordination provisions of the Notes and the Indenture; (c)
failure to provide a Company Notice in the event of a Change in Control, whether
or not such notice is prohibited by the subordination provisions of the Notes
and the Indenture; (d) failure to perform any other covenant of the Company in
the Indenture, continuing for 60 days (plus an additional 60 days in the case of
defaults subject to cure, provided the Company commences such cure within the
initial 60 days and is diligently pursuing such cure) after written notice as
provided in the Indenture; (e) default in respect of any indebtedness for money
borrowed by the Company that results in acceleration of the maturity of an
amount in excess of $10,000,000 of indebtedness if such indebtedness is not
discharged, or such acceleration is not annulled, within 30 days after written
notice as provided in the Indenture; and (f) certain events of bankruptcy,
insolvency or reorganization. (Section 5.1) Subject to the provisions of the
Indenture relating to the duties of the Trustee in case an Event of Default
shall occur and be continuing, the Trustee will be 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. (Section 6.3) Subject to such provisions for the
indemnification of the Trustee, the Holders of a majority in aggregate principal
amount of the Outstanding Notes will 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. (Section 5.12)
 
    If an Event of Default shall occur and be continuing, either the Trustee or
the Holders of at least 25% in principal amount of the Outstanding Notes may,
subject to the subordination provisions of the Indenture, accelerate the
maturity of all Notes; provided, however, that after such acceleration, but
before a judgment or decree based on acceleration, the Holders of a majority in
aggregate principal amount of Outstanding Notes may, under certain
circumstances, rescind and annul such acceleration if all Events of Default,
other than the non-payment of principal of the Notes which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in the Indenture. (Section 5.2) For information as to waiver of
defaults, see "-- Meetings, Modification and Waiver."
 
    No Holder of any Note will have 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 notice of a continuing Event of
Default and the Holders of at least 25% in aggregate principal amount of the
Outstanding Notes 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 aggregate
principal amount of the Outstanding Notes a direction inconsistent with such
request and shall have failed to institute such proceeding within 60 days.
(Section 5.7) However, such limitations do not apply to a suit instituted by a
Holder of a Note for the enforcement of payment of the principal of, premium, if
any, or interest on such Note on or after the respective due dates expressed in
such Note or of the right to convert such Note in accordance with the Indenture.
(Section 5.8)
 
    The Company will be required to furnish to the Trustee annually a statement
as to the performance by the Company of certain of its obligations under the
Indenture and as to any default in such performance. (Section 10.9)
 
MEETINGS, MODIFICATION AND WAIVER
 
    The Indenture contains provision for convening meetings of the Holders of
Notes to consider matters affecting their interests. (Article Nine)
 
                                       20
<PAGE>
    Certain limited modifications of the Indenture may be made without the
necessity of obtaining the consent of the Holders of the Notes. Other
modifications and amendments of the Indenture may be made, and certain past
defaults by the Company may be waived, either (i) with the written consent of
the Holders of not less than a majority in aggregate principal amount of the
Notes at the time Outstanding or (ii) by the adoption of a resolution, at a
meeting of Holders of the Notes at which a quorum is present, by the Holders of
at least 66 2/3% in aggregate principal amount of the Notes represented at such
meeting. However, no such modification or amendment may, without the consent of
the Holder of each Outstanding Note affected thereby, (a) change the Stated
Maturity of the principal of, or any installment of interest on, any Note, (b)
reduce the principal amount of, or the premium, if any, or interest on, any
Note, (c) reduce the amount payable upon a redemption or mandatory repurchase,
(d) modify the provisions with respect to the repurchase right of the Holders in
a manner adverse to the Holders, (e) change the place or currency of payment of
principal of, premium, if any, or interest on, any Note (including any payment
of Liquidated Damages or of the Repurchase Price in respect of such Note), (f)
impair the right to institute suit for the enforcement of any payment on or with
respect to any Note, (g) modify the obligation of the Company to maintain an
office or agency in New York City, (h) except as otherwise permitted or
contemplated by provisions concerning consolidation, merger, conveyance,
transfer, sale or lease of all or substantially all of the property and assets
of the Company, adversely affect the right of Holders to convert any of the
Notes or to require the Company to repurchase any Note other than as provided in
the Indenture, (i) modify the subordination provisions in a manner adverse to
the Holders of the Notes, (j) reduce the above-stated percentage of Outstanding
Notes necessary to modify or amend the Indenture, (k) reduce the percentage of
aggregate principal amount of Outstanding Notes necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults, (l) reduce the percentage in aggregate principal amount of Outstanding
Notes required for the adoption of a resolution or the quorum required at any
meeting of Holders of Notes at which a resolution is adopted, or (m) modify the
obligation of the Company to deliver information required under Rule 144A to
permit resales of Notes and Common Stock issuable upon conversion thereof in the
event the Company ceases to be subject to certain reporting requirements under
the United States securities laws (SectionSection 8.2 and 5.13). The quorum at
any meeting called to adopt a resolution will be persons holding or representing
a majority in aggregate principal amount of the Notes at the time Outstanding
and, at any reconvened meeting adjourned for lack of a quorum, 25% of such
aggregate principal amount. (Section 9.4)
 
    The Holders of a majority in aggregate principal amount of the Outstanding
Notes may waive compliance by the Company with certain restrictive provisions of
the Indenture by written consent or by the adoption of a resolution at a
meeting. (Section 10.13) The Holders of a majority in aggregate principal amount
of the Outstanding Notes also may waive any past default under the Indenture,
except a default in the payment of principal, premium, if any, or interest, by
written consent. (Section 5.13)
 
TRANSFER, EXCHANGE AND WITHDRAWAL
 
    At the option of the Holder upon request confirmed in writing, and subject
to the terms of the Indenture, any Registered Note will be exchangeable at any
time into an equal aggregate principal amount of Registered Notes of different
authorized denominations provided that any applicable transfer restrictions are
satisfied. (Section 3.5)
 
    Registered Notes may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed) or exchange, at the office of
any transfer agent or at the office of the security registrar, without service
charge but, in the case of a transfer, upon payment of any taxes and other
governmental charges as described in the Indenture. Any registration of transfer
or exchange will be effected upon the transfer agent or the security registrar,
as the case may be, being satisfied with the documents of title and identity of
the person making the request, and subject to such reasonable regulations as the
Company may from time to time agree upon with the transfer agents and the
security registrar, all as described in the Indenture. Subject to the applicable
transfer restrictions, Registered Notes may be transferred in whole or in part
in authorized denominations. (Section 3.5)
 
                                       21
<PAGE>
    The Company has initially appointed the Trustee as security registrar and
transfer agent, acting through its Corporate Trust Office in New York City. The
Company reserves the right to vary or terminate the appointment of the security
registrar or of any transfer agent or to appoint additional or other transfer
agents or to approve any change in the office through which any security
registrar or any transfer agent acts. (SectionSection 3.5 and 10.2)
 
    In the event of a redemption of the Notes for any of the reasons set forth
below under "-- Redemption," the Company will not be required (a) to register
the transfer or exchange of Notes for a period of 15 days immediately preceding
the date notice is given identifying the serial numbers of the Notes called for
such redemption or (b) to register the transfer of or exchange any Registered
Note, or portion thereof, called for redemption. (Section 2.2)
 
    EXCHANGE OF INTERESTS IN REGISTERED GLOBAL NOTES FOR REGISTERED CERTIFICATED
NOTES.  As long as DTC, or its nominee, is the registered Holder of a Registered
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner and Holder of the Notes represented by such Registered Global Note
for all purposes under the Indenture and the Notes. Unless DTC notifies the
Company that it is unwilling or unable to continue as depository for a
Registered Global Note, or ceases to be a "Clearing Agency" registered under the
Exchange Act, or announces an intention permanently to cease business or does in
fact do so, or an Event of Default has occurred and is continuing with respect
to a Registered Global Note, owners of beneficial interests in a Registered
Global Note will not be entitled to have any portions of such Registered Global
Note registered in their names, will not receive or be entitled to receive
physical delivery of Notes in definitive form and will not be considered the
owners or Holders of the Registered Global Note (or any Notes represented
thereby) under the Indenture or the Notes. In addition, no beneficial owner of
an interest in a Registered Global Note will be able to transfer that interest
except in accordance with DTC's applicable procedures (in addition to those
under the Indenture referred to herein). In the event that owners of beneficial
interests in a Registered Global Note become entitled to receive Registered
Notes in certificated form, such Notes will be issued only as Registered Notes
in certificated form in denominations of U.S.$1,000 and integral multiples
thereof.
 
    EXCHANGE OF REGISTERED CERTIFICATED NOTES FOR INTERESTS IN REGISTERED GLOBAL
NOTES.  Regulation D Notes, which initially were issued in certificated (i.e.,
non-global) form, may not be exchanged for beneficial interests in any
Registered Global Note unless such exchange occurs in connection with or
following a transfer of such Regulation D Notes and, in the case of initial
purchasers thereof, the transferor first delivers to the Trustee a written
certificate (in the form provided in the Indenture) to the effect that such
transfer will comply with the appropriate transfer restrictions applicable to
such Notes as set forth in Appendix III to this Prospectus. In the case of any
such exchange of a Regulation D Note initially issued in certificated form for
(a) an interest in the Regulation S Global Note, such transfer must occur
pursuant to Regulation S or Rule 144 (if available) or (b) an interest in the
Restricted Global Note, such transfer must occur pursuant to Rule 144A.
 
    EXCHANGES BETWEEN THE REGULATION S GLOBAL NOTE AND THE RESTRICTED GLOBAL
NOTE.  Prior to the expiration of the Restricted Period, beneficial interests in
the Regulation S Global Note may be exchanged for beneficial interests in the
Restricted Global Note only if such exchange occurs in connection with a
transfer of the Notes pursuant to Rule 144A and the transferor first delivers to
the Trustee a written certificate (in the form provided in the Indenture) to the
effect that the Notes are being transferred to a person who the transferor
reasonably believes is a qualified institutional buyer within the meaning of
Rule 144A under the Securities Act, purchasing for its own account or the
account of a qualified institutional buyer in a transaction meeting the
requirements of Rule 144A and in accordance with all applicable securities laws
of the states of the United States and other jurisdictions.
 
    Beneficial interests in the Restricted Global Note may be transferred to a
person who acquires the same in the form of a beneficial interest in the
Regulation S Global Note, whether before or after the expiration of the
Restricted Period, only if the transferor first delivers to the Trustee a
written
 
                                       22
<PAGE>
certificate (in the form provided in the Indenture) to the effect that such
transfer is being made in accordance with Rule 904 of Regulation S or Rule 144
(if available) and that, if such transfer occurs prior to the expiration of the
Restricted Period, the interest transferred will be held immediately thereafter
through Euroclear or CEDEL.
 
    Any beneficial interest in one of the Registered Global Notes that is
transferred to a person who takes delivery in the form of an interest in the
other Registered Global Note will, upon transfer, cease to be an interest in
such Registered Global Note and will become an interest in the other Registered
Global Note and, accordingly, will thereafter be subject to all transfer
restrictions and other procedures applicable to beneficial interests in such
other Registered Global Note for so long as it remains such an interest.
 
    Transfers involving an exchange of a beneficial interest in the Regulation S
Global Note for a beneficial interest in the Restricted Global Note or vice
versa will be effected in DTC by means of an instruction originated by the
Trustee through the DTC/Deposit Withdraw at Custodian (DWAC) system.
Accordingly, appropriate adjustments will be made to reflect a decrease in the
principal amount of the Regulation S Global Note and a corresponding increase in
the principal amount of the Restricted Global Note or vice versa, as applicable.
 
TITLE
 
    The Company, the Trustee, any Paying Agent and any Conversion Agent may
treat the registered owner (as reflected in the Security Register) of any Note
as the absolute owner thereof (whether or not such Note shall be overdue) for
the purpose of making payment and for all other purposes. (Section 2.2)
 
NOTICES
 
    Notice to Holders of the Notes will be given by mail to the addresses of
such Holders as they appear in the Security Register. Such notices will be
deemed to have been given on the date of such mailing. (SectionSection 1.1 and
1.6)
 
    Notice of a redemption of Notes will be given at least once not less than 30
nor more than 60 days prior to the redemption date (which notice shall be
irrevocable) and will specify the redemption date.
 
REPLACEMENT OF NOTES
 
    Notes that become mutilated, destroyed, stolen or lost will be replaced by
the Company at the expense of the Holder upon delivery to the Trustee of the
mutilated Notes or evidence of the loss, theft or destruction thereof
satisfactory to the Company and the Trustee. In the case of a lost, stolen or
destroyed Note, indemnity satisfactory to the Trustee and the Company may be
required at the expense of the Holder of such Note before a replacement Note
will be issued. (Section 3.6)
 
PAYMENT OF STAMP AND OTHER TAXES
 
    The Company will pay all stamp and other duties, if any, which may be
imposed by the United States or the United Kingdom or any political subdivision
thereof or taxing authority thereof or therein with respect to the issuance of
the Notes. The Company will not be required to make any payment with respect to
any other tax, assessment or governmental charge imposed by any government or
any political subdivision thereof or taxing authority thereof or therein.
 
DEPOSITORY PROCEDURES WITH RESPECT TO REGISTERED GLOBAL NOTES
 
    With respect to the Registered Global Notes, DTC has advised the Company as
follows: DTC 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 Uniform Commercial Code, as amended, and
a "Clearing Agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. DTC was created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the clearance
and settlement of transactions in those securities between Participants through
electronic book-entry changes in accounts of its Participants. The Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations. Access to DTC's system is also
available to other entities such as banks,
 
                                       23
<PAGE>
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants"). Persons who are not Participants may beneficially
own securities held by or on behalf of DTC only through the Participants or the
Indirect Participants. The ownership interest and transfer of ownership interest
of each actual purchaser of each security held by or on behalf of DTC are
recorded on the records of the Participants and Indirect Participants.
 
    DTC has also advised the Company that pursuant to procedures established by
it, (i) upon deposit of the Registered Global Notes, DTC will credit the
accounts of Participants designated by the Purchasers with portions of the
principal amount of the Registered Global Notes and (ii) ownership of such
interests in the Registered Global Notes will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC (with
respect to the Participants) or by the Participants and the Indirect
Participants (with respect to other owners of beneficial interest in the
Registered Global Notes).
 
    Investors in the Restricted Global Note may hold their interests therein
directly through DTC, if they are Participants in such system, or indirectly
through organizations (including Euroclear and CEDEL) which are Participants in
such system. Investors in the Regulation S Global Note, which will be issued
only after the expiration of the Restricted Period (but not earlier), may hold
interests therein through Euroclear or CEDEL or organizations other than
Euroclear and CEDEL that are Participants in the DTC system. Euroclear and CEDEL
will hold interests in the Regulation S Global Note on behalf of their
Participants through customers' securities accounts in their respective names on
the books of their respective depositaries, which are Morgan Guaranty Trust
Company of New York, Brussels office, as operator of Euroclear, and Citibank,
N.A., as operator of CEDEL. The depositaries, in turn, will hold such interests
in the Regulation S Global Note in customers' securities accounts in the
depositaries' names on the books of DTC. All interests in a Registered Global
Note, including those held through Euroclear or CEDEL, may be subject to the
procedures and requirements of DTC. Those interests held through Euroclear or
CEDEL may also be subject to the procedures and requirements of such system.
 
    The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a Registered Global Note to such persons may be
limited to that extent. Because DTC can act only on behalf of its Participants,
which in turn act on behalf of Indirect Participants and certain banks, the
ability of a person having beneficial interests in a Registered Global Note to
pledge such interests to persons or entities that do not participate in the DTC
system, or otherwise take actions in respect of such interests, may be affected
by the lack of a physical certificate evidencing such interests.
 
    EXCEPT AS DESCRIBED ABOVE UNDER "-- TRANSFER, EXCHANGE AND WITHDRAWAL,"
OWNERS OF INTERESTS IN THE REGISTERED GLOBAL NOTES WILL NOT HAVE NOTES
REGISTERED IN THEIR NAMES, WILL NOT RECEIVE PHYSICAL DELIVERY OF NOTES IN
CERTIFICATED FORM AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS OR HOLDERS
THEREOF UNDER THE INDENTURE FOR ANY PURPOSE.
 
    DTC has advised the Company that its current practice, upon receipt of any
payment in respect of interests in securities such as the Registered Global
Notes (including principal and interest) held by it or its nominee, is to credit
the accounts of the relevant Participants with the payment on the payment date,
in amounts proportionate to their respective holdings in principal amount of
beneficial interests in the relevant security such as the Registered Global
Notes as shown on the records of DTC unless DTC has reason to believe it will
not receive payment on such payment date. Payments by the Participants and the
Indirect Participants to the beneficial owners of Notes will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers registered in "street name." Such
payments will be the responsibility of the Participants or the Indirect
Participants and will not be the responsibility of DTC, the Trustee or the
Company. Neither the Company nor the Trustee will be liable for any delay by DTC
or any of its Participants in
 
                                       24
<PAGE>
identifying the beneficial owners of the Notes, and the Company and the Trustee
may conclusively rely on and will be protected in relying on instructions from
DTC or its nominee as the registered owner of the Registered Global Notes for
all purposes.
 
    Transfers of beneficial interests in the Restricted Global Note between
Participants in DTC will be effected in accordance with DTC's procedures, and
such beneficial interests will trade in DTC's Same-Day Funds Settlement System;
and consequently, secondary market trading activity in such interests will
settle in immediately available funds. Transfers of beneficial interests in the
Regulation S Global Note between participants in Euroclear and CEDEL will be
effected in the ordinary way in accordance with their respective rules and
operating procedures, whereas cross-market transfers of such interests
(including, by DTC Participants other than Euroclear and CEDEL) will be subject
to considerations described below.
 
    Subject to compliance with the transfer restrictions applicable to the Notes
described herein, cross-market transfers with respect to the Registered Global
Notes between the Participants in DTC, on the one hand, and Euroclear or CEDEL
participants, on the other hand, will be effected through DTC in accordance with
DTC's rules on behalf of Euroclear or CEDEL, as the case may be, by its
respective depository; however, such cross-market transactions will require
delivery of instructions to Euroclear or CEDEL, as the case may be, by the
counterparts in such system in accordance with the rules and procedures and
within the established deadlines (Brussels time) of such system. Euroclear or
CEDEL, as the case may be, will, if the transaction meets its settlement
requirements, deliver instructions to its respective depositary to take action
to effect final settlement on its behalf by delivering or receiving interests in
the relevant Registered Global Note in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to
DTC. Euroclear participants and CEDEL participants may not deliver instructions
directly to the depositories for Euroclear or CEDEL.
 
    Because of time zone differences, the securities account of a Euroclear or
CEDEL participant purchasing an interest in a Registered Global Note from a
Participant in DTC will be credited, and any such crediting will be reported to
the relevant Euroclear or CEDEL participant, during the securities settlement
processing day (which must be a business day for Euroclear and CEDEL)
immediately following the settlement date of DTC. Cash received in Euroclear or
CEDEL as a result of sales of interests in a Registered Global Note by or
through a Euroclear or CEDEL participant to a Participant in DTC will be
received with value on the settlement date of DTC but will be available in the
relevant Euroclear or CEDEL cash account only as of the business day for
Euroclear or CEDEL following DTC's settlement date.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a Holder of Notes only at the direction of one or more Participants to
whose account with DTC interests in the Registered Global Notes are credited and
only in respect of such portion of the aggregate principal amount of the Notes
as to which such Participant or Participants has or have given such direction.
However, if there is an Event of Default under the Notes, DTC reserves the right
to exchange the Registered Global Notes for legended Notes in certificated form,
and to distribute such Notes to its Participants.
 
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of beneficial ownership interests in the Registered Global Notes among
Participants of DTC, it is under no obligation to perform or continue to perform
such procedures, and such procedures may be discontinued at any time. None of
the Company, the Trustee nor any of their respective agents will have any
responsibility for the performance by DTC, its Participants or Indirect
Participants of their respective obligations under the rules and procedures
governing their operations, including maintaining, supervising or reviewing the
records relating to, or payments made on account of, beneficial ownership
interests in Registered Global Notes.
 
                                       25
<PAGE>
GOVERNING LAW
 
    The Indenture and the Notes will be governed by and construed in accordance
with the laws of the State of New York, United States of America. (Section 1.11)
 
THE TRUSTEE
 
    In case an Event of Default shall occur (and shall not be cured), the
Trustee will be required to use the degree of care of a prudent person in the
conduct of his own affairs in the exercise of its powers. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request of any of the Holders of
Notes, unless they shall have offered to the Trustee reasonable security or
indemnity. (SectionSection 6.1 and 6.3)
 
                              PLAN OF DISTRIBUTION
 
    The Notes were issued to the Selling Securityholders in connection with an
underwritten private placement. The Notes may be sold from time to time by the
Selling Securityholders. The Selling Securityholders may from time to time sell
all or a portion of the Notes in transactions on the Nasdaq National Market, in
the over-the-counter market, in negotiated transactions, or a combination of
such methods of sale, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. The Notes may
be sold directly or through broker-dealers. If shares of Common Stock are sold
through broker-dealers, the Selling Securityholders may pay brokerage
commissions and charges. The methods by which the Notes may be sold include (a)
a block trade (which may involve crosses) in which the broker or dealer so
engaged will attempt to sell the securities as agent but may position and resell
a portion of the block as principal to facilitate the transaction; (b) purchases
by a broker or dealer as principal and resale by such broker or dealer for its
own account pursuant to this Prospectus; (c) exchange distributions and/or
secondary distributions in accordance with the rules of the Nasdaq National
Market; (d) ordinary brokerage transactions and transactions in which the broker
solicits purchasers; and (e) privately negotiated transactions.
 
    Pursuant to the provisions of the Registration Rights Agreement entered into
by and between the Company and Goldman, Sachs & Co., the Company will pay the
costs and expenses incident to its registration and qualification of the Notes
offered hereby, including registration and filing fees. In addition, the Company
has agreed to indemnify the Selling Securityholders against certain liabilities,
including liabilities arising under the Securities Act.
 
    The Selling Securityholders and any broker-dealer participating in the
distribution of the Notes may be deemed to be "underwriters" within the meaning
of the Securities Act, and any profit and any commissions paid or any discounts
or concessions allowed to any such broker-dealer may be deemed to be
underwriting discounts and commissions under the Securities Act. The Selling
Securityholders may indemnify any broker-dealer that participates in
transactions involving the sale of Notes against certain liabilities, including
liabilities under the Securities Act.
 
    There can be no assurances that the Selling Securityholders will sell any or
all of the Notes offered by them hereunder.
 
                                 LEGAL MATTERS
 
    The validity of the securities offered hereby will be passed upon by Vinson

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Pursuant to Section 102(b)(7) of the Delaware General Corporation Law (the
"DGCL"), the Company has included in its Restated Certificate of Incorporation,
as amended, a provision that eliminates the personal liability of a director to
the Company or its stockholders for monetary damages for breach of his fiduciary
duty as a director except for (i) any breach of the duty of loyalty to the
Company or its stockholders, (ii) acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) payment of
an improper dividend or improper repurchase or improper redemption of the
Company's stock under Section 174 of the DGCL or (iv) any transaction from which
the director derived an improper personal benefit. The Company's Restated
Certificate of Incorporation, as amended, further provides that in the event the
DGCL is amended to allow the further elimination or limitation of the liability
of directors, then the liability of the Company's directors shall be eliminated
or limited to the fullest extent permitted by the amended DGCL.
 
    Pursuant to Section 145 of the DGCL, the Company has included in its Bylaws,
as amended, provisions that require the Company to indemnify its directors,
officers, employees and agents to the fullest extent permitted by the DGCL. The
Company is required to indemnify any person who was or is (or is threatened to
be made) a party to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Company) by reason of the fact that such
person is or was a director, officer, employee or agent of the Company, or is or
was serving at the request of the Company as a director, officer, employee or
agent of another corporation or enterprise. The indemnity includes expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,
suit or proceeding, provided such director, officer, employee or agent acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
Company's best interests and, with respect to any criminal action or proceeding,
provided he had no reasonable cause to believe that his conduct was unlawful.
 
    In addition, the Company is required to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Company to procure a judgment
in its favor by reason of the fact that he is or was a director, officer,
employee or agent of the Company or is or was serving in such role in another
enterprise at the request of the Company. The indemnity includes expenses
(including attorneys' fees) actually and reasonably incurred by him, provided
the officer or director acted in good faith and in a manner he
 
                                      II-1
<PAGE>
reasonably believed to be in or not opposed to the Company's best interests.
However, no such person will be indemnified as to matters for which he is found
to be liable to the Company unless, and only to the extent that, indemnification
is ordered by a court.
 
    Pursuant to Section 145(g) of the DGCL, the Company's Bylaws, as amended,
authorize the Company to obtain insurance to protect officers and directors from
certain liabilities, including liabilities against which the Company cannot
indemnify its directors and officers.

ITEM 17.  UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes:
 
<TABLE>
<S>        <C>        <C>
(1)        (i)        To file, during any period in which offers or sales are being made, a
                      post-effective amendment to this Registration Statement:
 
           (ii)       To include any prospectus required in Section 10(a) (3) of the Securities Act of
                      1933, as amended (the "Securities Act");
 
           (iii)      To reflect in the prospectus any facts or events arising after the effective
                      date of the Registration Statement (or the most recent post-effective amendment
                      thereof) which, individually or in the aggregate, represent a fundamental change
                      in the information set forth in the Registration Statement. Notwithstanding the
                      foregoing, any increase or decrease in volume of securities offered (if the
                      total dollar value of securities offered would not exceed that which was
                      registered) and any deviation from the low or high end of the estimated maximum
                      offering range may be reflected in the form of Prospectus filed with the
                      Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
                      and price represent no more than a 20% change in the maximum aggregate offering
                      price set forth in the "Calculation of Registration Fee" table in the effective
                      Registration Statement;
 
           (iv)       To include any material information with respect to the plan of distribution not
                      previously disclosed in the Registration Statement or any material change to
                      such information in the Registration Statement;
</TABLE>
 
PROVIDED, HOWEVER, that paragraphs (1)(ii) and (1)(iii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act") that are incorporated by reference in the Registration
Statement.
 
    (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (4) That, for purposes of determining any liability under the Securities
Act, each filing of the Registrant's annual report pursuant to section 13(a) or
section 15(d) of the Exchange Act that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, 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 Securities Act and will be governed by the final
adjudication of such issue.

Goldman, Sachs & Co.,
85 Broad Street,
New York, New York 10004.

Ladies and Gentlemen:

   Cyrix Corporation, a Delaware corporation (the "Company"), proposes, 
subject to the terms and conditions stated herein, to issue and sell to you 
(the "Purchaser") an aggregate of U.S.$110,000,000 principal amount of the 
5 1/2 % Convertible Subordinated Notes due June 1, 2001, convertible into 
Common Stock, par value U.S.$.004 per share (the "Stock"), of the Company, 
specified above (the "Firm Securities"), and, at the election of the 
Purchaser, up to an aggregate of U.S.$16,500,000 additional aggregate 
principal amount of such Notes (the "Optional Securities"). The Firm 
Securities and the Optional Securities which the Purchaser elect to purchase 
pursuant to Section 2 hereof are herein collectively called the "Securities". 
 As used herein, the term "Securities" shall be deemed, unless the context 
otherwise requires, to include the Securities in the form of a temporary 
global Security representing the Securities issued and sold in reliance on 
Regulation S, and the term "Purchaser" shall be deemed to include Goldman 
Sachs International ("GSI"), who is acting as your selling agent in making 
certain resales of the Securities pursuant to Section 3.

   The Purchaser and other holders (including subsequent transferees) of 
Securities in registered form without coupons will be entitled to the 
benefits of the registration rights agreement, to be dated as of the Time of 
Delivery (as defined below) (the "Registration Rights Agreement") among the 
Company and the Purchaser, in the form attached hereto as Exhibit A.  
Pursuant to the Registration Rights Agreement, the Company will agree to file 
with the Securities and Exchange Commission (the "Commission") under the 
circumstances set forth therein a shelf registration statement pursuant to 
Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"), 
relating to the resale of (i) such Securities and (ii) the shares of Stock 
initially issuable upon conversion of the Securities by holders thereof, and 
to use its reasonable efforts to cause such shelf registration statement to 
be declared effective.

   1.   The Company represents and warrants to, and agrees with, the 
Purchaser that:

          (a)  An offering circular dated May 22, 1996 (the "Offering 
     Circular"), including the international supplement thereto, has been 
     prepared in connection with the offering of the Securities and the 
     shares of Stock issuable upon conversion thereof. Any reference herein 
     to the Offering Circular shall be deemed to refer to and include the 
     Company's Annual Report on Form 10-K for the year ended December 31, 
     1995, Annual Report on 10-K/A for the year ended December 31, 1995, as 
     amended by the Company's

<PAGE>

     Amendment No. 1 on Form 10-K/A filed with the Commission on May 20, 
     1996, and Quarterly Report on Form 10-Q for the quarter ended March 31, 
     1996 attached to and made a part of the Offering Circular and all 
     subsequent documents filed with the Commission pursuant to Section 
     13(a), 13(c) or 15(d) of the Securities Exchange Act of 1934, as amended 
     (the "Exchange Act"), on or prior to the date of the Offering Circular; 
     and any reference to the Offering Circular as amended or supplemented as 
     of any specified date shall be deemed to include (i) any documents filed 
     with the Commission pursuant to Section 13(a), 13(c) or 15(d) of the 
     Exchange Act after the date of the Offering Circular and prior to such 
     specified date and (ii) any Additional Issuer Information (as defined in 
     Section 5(g) of this Agreement) furnished by the Company prior to the 
     completion of the distribution of the Securities; and all documents 
     filed under the Exchange Act and so deemed to be included in the 
     Offering Circular or any amendment or supplement thereto are hereinafter 
     called the "Exchange Act Reports".   The Exchange Act Reports, when they 
     were or are filed with the United States Securities and Exchange 
     Commission (the "Commission"), conformed or will conform in all material 
     respects to the applicable requirements of the Exchange Act and the 
     applicable rules and regulations of the Commission thereunder.  The 
     Offering Circular and any amendments or supplements thereto did not and 
     will not, as of their respective dates, contain an untrue statement of a 
     material fact or omit to state a material fact necessary in order to 
     make the statements therein, in light of the circumstances under which 
     they were made, not misleading; provided, however, that this 
     representation and warranty shall not apply to any statements or 
     omissions made in reliance upon and in conformity with information 
     furnished in writing to the Company by you expressly for use therein;

          (b)  Neither the Company nor any of its subsidiaries has sustained 
     since the date of the latest audited consolidated financial statements 
     of the Company included in the Offering Circular any material loss or 
     interference with its business from fire, explosion, flood or other 
     calamity, whether or not covered by insurance, or from any labor dispute 
     or court or governmental action, order or decree, otherwise than as set 
     forth or contemplated in the Offering Circular; and, since the 
     respective dates as of which information is given in the Offering 
     Circular, there has not been any change in the capital stock or 
     long-term debt of the Company or any of its subsidiaries or any material

     information as they may reasonably request to enable them to pass upon 
     such matters;

          (b)  Vinson & Elkins, counsel for the Company, shall have furnished

          and the Indenture, will be duly and validly issued, fully paid and 
          non-assessable and will conform to the description of the Stock

          failure to be so qualified in any such jurisdiction (such counsel 
          being entitled to rely in respect of the opinion in this clause 
          upon opinions of local counsel or, without any other investigation, 
          certificates of public officials, and in respect of matters of fact

          justified in relying upon such opinions and certificates);

               (iv) Each subsidiary of the Company listed on Schedule II to 
          this Agreement (a "Specified Subsidiary") has been duly

          owned of record directly or indirectly by the Company, free and 
          clear of all liens, encumbrances, equities or claims known to such 
          counsel (such counsel being entitled to rely in respect of the

          respect of matters of fact upon certificates of officers of the 
          Company or its subsidiaries, provided that such counsel shall state

          upon such opinions and certificates);

              (v)  To the best of such counsel's knowledge and other than as 
          set forth in the Offering Circular, there are no legal or 
          governmental proceedings pending to which the Company or any of its 
          subsidiaries is a party or of which any property of the Company or 
          any of its subsidiaries is the subject which are expected 
          individually or in the aggregate to have a material adverse effect 
          on the current or future consolidated financial position, 
          stockholders' equity or results of operations of the Company and 
          its subsidiaries taken as a whole; and, to the best of such 
          counsel's knowledge, no such proceedings are threatened or 
          contemplated by governmental authorities or threatened by others;

               (vi) This Agreement has been duly authorized, executed and 
          delivered by the Company;

               (vii) The Securities have been duly authorized, executed, 
          issued and delivered by the Company and, assuming due 
          authentication by the Trustee, constitute valid and legally binding 
          obligations of the Company entitled to the benefits provided by the 
          Indenture; and the Securities and the Indenture conform to the 
          descriptions thereof in the Offering Circular in all material 
          respects;

               (viii)  The Indenture has been duly authorized, executed and 
          delivered by the Company and constitutes a valid and legally 
          binding instrument, enforceable in accordance with its terms,

          conveyance, reorganization and other laws of general applicability 
          relating to or affecting creditors' rights and to general equity 
          principles;

               (ix) The issue and sale of the Securities, the issuance of the 
          Stock upon conversion of the Securities and the compliance by the 
          Company with all of the provisions of the Securities, the Indenture 
          and this Agreement and the consummation of the transactions herein 
          and therein contemplated will not conflict with or result in a 
          breach or violation of any of the terms or provisions


                                      -11-

          of, or constitute a default under, any material indenture, 
          mortgage, deed of trust, loan agreement or other agreement or 
          instrument listed in an officer's certificate as constituting all 
          such material agreements or otherwise known to such counsel to 
          which the Company or any of its subsidiaries is a party or by which 
          the Company or any of its Specified Subsidiaries is bound or to 
          which any of the property or assets of the Company or any of its 
          subsidiaries is subject, except any conflict, breach, violation or 
          default which individually or in the aggregate would not have a 
          material adverse effect on the general affairs, management, 
          financial position, stockholders' equity or results of operations 
          of the Company and its subsidiaries taken as a whole, nor will such 
          action result in any violation of the provisions of the Certificate 
          of Incorporation or By-laws of the Company or any statute or any 
          order, rule or regulation of any court or governmental agency or 
          body having jurisdiction over the Company or any of its 
          subsidiaries or any of their properties;

               (x)  No consent, approval, authorization, order, registration 
          or qualification of or with any court or governmental agency or

          thereof is required for the issue and sale of the Securities, the 
          issuance of the Stock upon conversion of the Securities or the 
          consummation of the transactions contemplated by this Agreement or 
          the Indenture, other than such consents, approvals, authorizations, 
          registrations or qualifications as may be required under "blue sky" 
          or foreign securities laws in connection with the purchase and 
          distribution of the Securities by the Purchaser or which this 
          Agreement or the Indenture contemplate will be obtained or made 
          after the Time of Delivery;

               (xi) The statements set forth in the Offering Circular under 
          the caption "Description of Notes" and "Description of Capital 
          Stock", insofar as they purport to constitute a summary of the 
          terms of the Securities and the Stock and under the caption "Offer 
          and Resale", insofar as they purport to describe the provisions of 
          the laws and document referred to therein, are accurate and 
          complete in all material respects and fair;

               (xii)  No registration of the Securities under the 
          Securities Act, and no qualification of an indenture under the

          thereto, is required for the offer and sale of the Securities in 
          the manner contemplated by this Agreement (including the provisions 
          of Annex I to this Agreement), and the Offering Circular;

               (xiii) The Exchange Act Reports (other than the financial 
          statements and related schedules therein, as to which such counsel 
          need express no opinion), when they were filed with the Commission, 
          complied appeared on their face to comply as to form in all 
          material respects with the requirements of the Exchange Act, and 
          the rules and regulations of the Commission thereunder; and

               (xiv)  The Company is not an open-end investment company, unit 
          investment trust, closed-end investment company or face-amount

               In addition, such opinion shall also contain a statement that, 
               based on the discussions and conferences disclosed in such 
               statement, and while such counsel assumes no responsibility 
               for the Exchange Act Reports mentioned below, no facts have 
               come to such counsel's attention that lead them to believe 
               that the Exchange Act Reports (other than financial statements 
               and related schedules and other financial data included 
               therein), when they were filed with the Commission, or the 
               Offering Circular or any further amendment or supplement 
               thereto made by the Company prior to the Time of Delivery 
               (other than the financial statements and related schedules and 
               other financial data included therein), as of its date or as 
               of the Time of Delivery, contained an untrue statement of 
               material fact or omitted to state a material fact necessary to 
               make the statements therein, in the light of the circumstances 
               under which they were made, not misleading.

          (c)  At 10:00 a.m., New York City time on the business day 
     preceding the date of this Agreement, and also at such Time of Delivery, 
     Ernst & Young LLP shall have furnished to you a letter or letters, dated 
     the respective date of delivery thereof, in form and substance 
     satisfactory to you to the effect set forth in Annex II hereto and to 
     such other matters as you may reasonably request;

          (d)  (i) Neither the Company nor any of its subsidiaries shall have 
     sustained since the date of the latest audited financial statements of 
     the Company included in the Offering Circular any loss or interference 
     with its business from fire, explosion, flood or other calamity, whether 
     or not covered by insurance, or from any labor dispute or court or 
     governmental action, order or decree, otherwise than as set forth or 
     contemplated in the Offering Circular, and (ii) since the respective 
     dates as of which information is given in the Offering Circular there 
     shall not have been any change in the capital stock or long-term debt of 
     the Company or any of its subsidiaries or any change, or any development 
     involving a prospective change, in or affecting the general affairs, 
     management, financial position, stockholders' equity or results of 
     operations of the Company and its subsidiaries, otherwise than as set 
     forth or contemplated in the Offering Circular, the effect of which, in 
     any such case described in clause (i) or (ii), is in the judgment of the 
     Purchaser so material and adverse as to make it impracticable or 
     inadvisable to proceed with the offering or the delivery of the 
     Securities being issued at such Time of Delivery on the terms and in the 
     manner contemplated in the Offering Circular;

          (e)  On or after the date hereof (i) no downgrading shall have 
     occurred in the rating accorded the Securities or any other debt 
     securities of the Company by any "nationally recognized statistical 
     rating organization", as that term is defined by the Commission for 
     purposes of Rule 436(g)(2) under the Securities Act and (ii) no such 
     organization shall have publicly announced that it has under 
     surveillance or review, with possible negative implications, its rating 
     of the Securities or any of the Company's other debt securities;

          (f)  On or after the date hereof there shall not have occurred any 
     of the following: (i) a suspension or material limitation in trading in 
     securities generally on the New York Stock Exchange or on NASDAQ; (ii) a 
     suspension or material limitation in trading in the Company's securities 
     on NASDAQ; (iii) a general moratorium on 


                                     -13-


<PAGE>

     commercial banking activities in New York declared by either Federal or 
     New York State authorities; (iv) the outbreak or the escalation of 
     hostilities involving the United States or the declaration by the United 
     States, on or after the date hereof, of a national emergency or war; or 
     (v) the occurrence of any change in national or international financial, 
     political or economic conditions or currency exchange rates or controls, 
     if the effect of any event specified in this clauses (iv) or (v) above, 
     in the judgment of the Purchaser, makes it impracticable or inadvisable 
     to proceed with the offering or the delivery of the Securities being 
     issued at such Time of Delivery on the terms and in the manner 
     contemplated in the Offering Circular; and

          (g)  The Company shall have furnished or caused to be furnished to 
     you at such Time of Delivery certificates of officers of the Company 
     satisfactory to you as to the accuracy of the representations and 
     warranties of the Company herein at and as of such Time of Delivery, as 
     to the performance by the Company of all of its obligations hereunder to 
     be performed at or prior to such Time of Delivery, as to the matters set 
     forth in subsection (d) of this Section and as to such other matters as 
     you may reasonably request.

     8.   (a)  The Company will indemnify and hold harmless the Purchaser 
against any losses, claims, damages or liabilities, joint or several, to 
which the Purchaser may become subject insofar as such losses, claims, 
damages or liabilities (or actions in respect thereof) arise out of or are 
based upon an untrue statement or alleged untrue statement of a material fact 
contained in the Offering Circular, or any amendment or supplement thereto, 
or arise out of or are based upon the omission or alleged omission to state 
therein a material fact necessary to make the statements therein, in the 
light of the circumstances under which they are made, not misleading, and 
will periodically reimburse the Purchaser for any legal or other expenses 
reasonably incurred by the Purchaser in connection with investigating or 
defending any such action or claim as such expenses are incurred, it being 
understood that the Company shall not, in connection with any one such action 
or separate but substantially similar related actions arising out of the same 
general allegations or circumstances, be liable for the fees and expenses of 
more than one separate firm or attorneys (other than local counsel) for all 
indemnified parties; PROVIDED, HOWEVER, that the Company shall not be liable 
in any such case to the extent that any such loss, claim, damage or liability 
arises out of or is based upon an untrue statement or alleged untrue 
statement or omission or alleged omission made in the Offering Circular or 
any such amendment or supplement in reliance upon and in conformity with 
written information furnished to the Company by the Purchaser expressly for 
use therein.

     (b)  The Purchaser will indemnify and hold harmless the Company against 
any losses, claims, damages or liabilities to which the Company may become 
subject insofar as such losses, claims, damages or liabilities (or actions in 
respect thereof) arise out of or are based upon any untrue statement or 
alleged untrue statement of a material fact contained in the Offering 
Circular, or any amendment or supplement thereto, or arise out of or are 
based upon the omission or alleged omission to state therein a material fact 
necessary to make the statements therein, in the light of the circumstances 
under which they are made, not misleading, in each case to the extent, but 
only to the extent, that such untrue statement or alleged untrue statement or 
omission or alleged omission was made in the Offering Circular or any such 
amendment or supplement in reliance upon and in conformity with written 
information furnished to the Company by you expressly for use therein; and 
will periodically 


                                     -14-


<PAGE>

reimburse the Company for any legal or other expenses reasonably incurred by 
the Company in connection with investigating or defending any such action or 
claim as such expenses are incurred, it being understood that the Purchaser 
shall not, in connection with any one such action or separate but 
substantially similar related actions arising out of the same general 
allegations or circumstances, be liable for the fees and expenses of more 
than one separate firm or attorneys (other than local counsel) for the 
Company.

     (c)  Promptly after receipt by an indemnified party under subsection (a) 
or (b) above of notice of the commencement of any action, such indemnified 
party shall, if a claim in respect thereof is to be made against the 
indemnifying party under such subsection, notify the indemnifying party in 
writing of the commencement thereof; but the omission so to notify the 
indemnifying party shall not relieve it from any liability which it may have 
to any indemnified party otherwise than under such subsection.  In case any 
such action shall be brought against any indemnified party and it shall 
notify the indemnifying party of the commencement thereof, the indemnifying 
party shall be entitled to participate therein and, to the extent that it 
shall wish, jointly with any other indemnifying party similarly notified, to 
assume the defense thereof, with counsel satisfactory to such indemnified 
party (who shall not, except with the consent of the indemnified party, be 
counsel to the indemnifying party), and, after notice from the indemnifying 
party to such indemnified party of its election so to assume the defense 
thereof, the indemnifying party shall not be liable to such indemnified party 
under such subsection for any legal expenses of other counsel or any other 
expenses, in each case subsequently incurred by such indemnified party, in 
connection with the defense thereof other than reasonable costs of 
investigation.  No indemnifying party shall, without the written consent of 
the indemnified party, effect the settlement or compromise of, or consent to 
the entry of any judgment with respect to, any pending or threatened action 
or claim in respect of which indemnification or contribution may be sought 
hereunder (whether or not the indemnified party is an actual or potential 
party to such action or claim) unless such settlement, compromise or judgment 
(i) includes an unconditional release of the indemnified party from all 
liability arising out of such action or claim and (ii) does not include a 
statement as to, or an admission of, fault, culpability or a failure to act, 
by or on behalf of any indemnified party.

     (d)  If the indemnification provided for in this Section 8 is 
unavailable to or insufficient to hold harmless an indemnified party under 
subsection (a) or (b) above in respect of any losses, claims, damages or 
liabilities (or actions in respect thereof) referred to therein, then each 
indemnifying party shall contribute to the amount paid or payable by such 
indemnified party as a result of such losses, claims, damages or liabilities 
(or actions in respect thereof) in such proportion as is appropriate to 
reflect the relative benefits received by the Company on the one hand and the 
Purchaser on the other from the offering of the Securities.  If, however, the 
allocation provided by the immediately preceding sentence is not permitted by 
applicable law or if the indemnified party failed to give the notice required 
under subsection (c) above, then each indemnifying party shall contribute to 
such amount paid or payable by such indemnified party in such proportion as 
is appropriate to reflect not only such relative benefits but also the 
relative fault of the Company on the one hand and the Purchaser on the other 
in connection with the statements or omissions which resulted in such losses, 
claims, damages or liabilities (or actions in respect thereof), as well as 
any other relevant equitable considerations.  The relative benefits received 
by the Company on the one hand and the Purchaser on the other shall be deemed 
to be in the same proportion as the total net 


                                     -15-


<PAGE>

proceeds from the offering (before deducting expenses) received by the 
Company bear to the total underwriting discounts and commissions received by 
the Purchaser.  The relative fault shall be determined by reference to, among 
other things, whether the untrue or alleged untrue statement of a material 
fact or the omission or alleged omission to state a material fact relates to 
information supplied by the Company on the one hand or the Purchaser on the 
other and the parties' relative intent, knowledge, access to information and 
opportunity to correct or prevent such statement or omission.  The Company 
and the Purchaser agree that it would not be just and equitable if 
contribution pursuant to this subsection (d) were determined by pro rata 
allocation or by any other method of allocation which does not take account 
of the equitable considerations referred to above in this subsection (d).  
The amount paid or payable by an indemnified party as a result of the losses, 
claims, damages or liabilities (or actions in respect thereof) referred to 
above in this subsection (d) shall be deemed to include any legal or other 
expenses reasonably incurred by such indemnified party in connection with 
investigating or defending any such action or claim.  Notwithstanding the 
provisions of this subsection (d), the Purchaser shall not be required to 
contribute any amount in excess of the amount by which the total price at 
which the Securities underwritten by it and distributed to purchasers were so 
offered exceeds the amount of any damages which the Purchaser has otherwise 
been required to pay by reason of such untrue or alleged untrue statement or 
omission or alleged omission.  No person guilty of fraudulent 
misrepresentation shall be entitled to contribution from any person who was 
not guilty of such fraudulent misrepresentation.

     (e)  The obligations of the Company under this Section 8 shall be in 
addition to any liability which the Company may otherwise have and shall 
extend, upon the same terms and conditions, to each person, if any, who 
controls the Purchaser; and the obligations of the Purchaser under this 
Section 8 shall be in addition to any liability which the respective 
Purchaser may otherwise have and shall extend, upon the same terms and 
conditions, to each officer and director of the Company and to each person, 
if any, who controls the Company.

     9.   The respective indemnities, agreements, representations, warranties 
and other statements of the Company and the Purchaser, as set forth in this 
Agreement or made by or on behalf of them, respectively, pursuant to this 
Agreement, shall remain in full force and effect, regardless of any 
investigation (or any statement as to the results thereof) made by or on 
behalf of the Purchaser or any controlling person of the Purchaser, or the 
Company or any officer or director or controlling person of the Company, and 
shall survive delivery of and payment for the Securities.

     10.  If the Purchaser shall default in its obligation to purchase the 
Securities which it has agreed to purchase hereunder, the Company shall not 
be under any liability to the Purchaser except as provided in Section 6 and 8 
hereof, but if for any other reason the Securities are not delivered by or on 
behalf of the Company as provided herein, the Company agrees to reimburse the 
Purchaser for all out-of-pocket expenses approved in writing by the 
Purchaser, including fees, disbursements and expenses of counsel, reasonably 
incurred by the Purchaser in making preparations for the purchase, sale and 
delivery of the Securities, but the Company shall then be under no further 
liability to the Purchaser except as provided in Sections 6 and 8 hereof.

     (1)  The Securities and the Stock issuable upon the conversion thereof 
have not been and will not be registered under the Securities Act and may not 
be offered or sold within the United States or to, or for the account or 
benefit of, U.S. persons except in accordance with Regulation S under the 
Securities Act or pursuant to an exemption from the registration requirements 
of the Securities Act.  The Purchaser represents that it has offered and 
sold, and will offer and sell, the Securities and the Stock issuable upon the 
conversion thereof (i) as part of its distribution at any time and (ii) 
otherwise until 40 days after the later of the commencement of the offering 
and the latest Time of Delivery, only in accordance with Rule 903 of 
Regulation S or Rule 144A or pursuant to paragraph (2) of this Annex I.  
Accordingly, the Purchaser agrees that neither it, its affiliates nor any 
persons acting on its or their behalf have engaged or will engage in any 
directed selling efforts with respect to the Securities or the Stock issuable 
upon conversion thereof.  The Purchaser agrees that, at or prior to 
confirmation of sale of Securities (other than a sale pursuant to Rule 144A 
or pursuant to paragraph (2) of this Annex I)), it will have sent to each 
distributor, dealer or person receiving a selling concession, fee or other 
remuneration that purchases Securities from it during the restricted period a 
confirmation or notice to substantially the following effect:

     "The Securities covered hereby and the Stock issuable upon the 
     conversion thereof have not been registered under the U.S. Securities 
     Act of 1933 (the "Securities Act") and may not be offered and sold 
     within the United States or to, or for the account or benefit of, U.S. 
     persons (i) as part of their distribution at any time or (ii) otherwise 
     until 40 days after the later of the commencement of the offering and 
     the closing date, except in either case in accordance with Regulation S 
     (or Rule 144A if available) under the Securities Act.  Terms used above 
     have the meaning given to them by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     The Purchaser further agrees that it has not entered and will not enter 
into any contractual arrangement with respect to the distribution or delivery 
of the Securities, except with its affiliates or with the prior written 
consent of the Company.

     (2)  Notwithstanding the foregoing, Securities in registered form may be 
offered, sold and delivered by the Purchaser in the United States and to U.S. 
persons in a manner designed to be exempt from the registration provisions of 
the Securities Act and the rules and regulations thereunder and without 
delivery of the written statement required by paragraph (1) above.  In 
connection therewith, Goldman, Sachs & Co. represents and warrants to, and 
agrees with, the Company that:


                                     -21-


<PAGE>

          (a)  It has offered and sold, and will offer and sell, Securities 
     and the Stock issuable upon conversion thereof only to persons that it 
     reasonably believes are (i) qualified institutional buyers within the 
     meaning of Rule 144A under the Act in transactions meeting the 
     requirements of such Rule 144A, or (ii) institutions that are 
     "accredited investors" within the meaning of Rule 501(a)(1), (2), (3) or 
     (7) under the Act; and

          (b)  It has offered the Securities to not more than 50 
     institutional accredited investors; each institutional accredited 
     investor that purchases Securities from it shall (i) purchase not less 
     than U.S.$250,000 principal amount of Securities, and (ii) execute and 
     deliver a purchaser's letter substantially in the form of Annex III to 
     the Offering Circular; and 

          (c)  It has not offered or sold, and will not offer or sell, 
     Securities or the Stock issuable upon the conversion thereof by any form 
     of general solicitation or general advertising, including but not 
     limited to the methods described in Rule 502(c) under the Securities Act.

     (3)  The Purchaser further represents and agrees that (i) it has not 
offered or sold, and will not offer or sell, in the United Kingdom by means 
of any document, any Securities other than to persons whose ordinary business 
it is to buy or sell debentures, whether as principal or as agent, or in 
circumstances which do not constitute an offer to the public within the 
meaning of the Companies Act 1985 of Great Britain, (ii) it has complied, and 
will comply, with all applicable provisions of the Financial Services Act 
1986 of Great Britain with respect to anything done by it in relation to the 
Securities in, from or otherwise involving the United Kingdom, and (iii) it 
has only issued or passed on, and will only issuance or pass on, in the 
United Kingdom, any document received by it in connection with the issuance 
of the Securities to a person who is of a kind described in Article 11(3) of 
the Financial Services Act 1986 (Investment Advertisements) (Exemptions) 
Order 1995 of Great Britain or is a person to whom the document may otherwise 
lawfully be issued or passed on.  

     (4)  The Purchaser agrees that it will not offer, sell or deliver any of 
the Securities in any jurisdiction outside of the United States except under 
circumstances that will result in compliance with the applicable laws 
thereof, and that it will take at its own expense whatever action is required 
to permit its purchase and resale of the Securities in such jurisdictions.  
The Purchaser understands that no action has been taken to permit a public 
offering in any jurisdiction outside of the United States where action would 
be required for such purpose.  The Purchaser agrees not to cause any 
advertisement of the Securities to be published in any newspaper or 
periodical or posted in any public place and not to issue any circular 
relating to the Securities, except in any such case with the Purchaser's 
express written consent and then only at its own risk and expense.

        Pursuant to Section 7(c) of the Purchase Agreement, Ernst & Young LLP 
shall have furnished at a time prior to the execution of the Purchase 
Agreement letters to the Purchaser to the effect that:

          (i)  They are independent auditors with respect to the Company and 
     its subsidiaries within the meaning of the Securities Exchange Act of 
     1934 (the "Exchange Act") and the applicable published rules and 
     regulations thereunder;

          (ii) In their opinion, the consolidated financial statements and 
     financial statement schedules audited by them and included in the 
     Offering Circular comply as to form in all material respects with the 
     applicable requirements of the Exchange Act and the related published 
     rules and regulations;

          (iii)     The unaudited selected financial information with respect 
     to the consolidated results of operations and financial position of the 
     Company for the five most recent fiscal years included in the Offering 
     Circular agrees with the corresponding amounts (after restatements where 
     applicable) in the audited consolidated financial statements for such 
     five fiscal years;

          (iv) On the basis of limited procedures not constituting an audit 
     in accordance with generally accepted auditing standards, consisting of 
     a reading of the unaudited financial statements and other information 
     referred to below, a reading of the latest available interim financial 
     statements of the Company and its subsidiaries, inspection of the minute 
     books of the Company and its subsidiaries since the date of the latest 
     audited financial statements included in the Offering Circular, 
     inquiries of officials of the Company and its subsidiaries responsible 
     for financial and accounting matters and such other inquiries and 
     procedures as may be specified in such letter, nothing came to their 
     attention that caused them to believe that:

               (A)  the unaudited consolidated statements of income, 
          consolidated balance sheets and consolidated statements of cash 
          flows included in the Offering Circular are not in conformity with 
          generally accepted accounting principles applied on the basis 
          substantially consistent with the basis for the unaudited condensed 
          consolidated statements of income, consolidated balance sheets and 
          consolidated statements of cash flows included in the Offering 
          Circular;

               (B)  any other unaudited income statement data and balance 
          sheet items included in the Offering Circular do not agree with the 
          corresponding items in the unaudited consolidated financial 
          statements from which such data and items were derived, and any 
          such unaudited data and items were not determined on a basis 
          substantially consistent with the basis for the corresponding 
          amounts in the audited consolidated financial statements included 
          in the Offering Circular;

               (C)  the unaudited financial statements which were not 
          included in the Offering Circular but from which were derived any 
          unaudited condensed financial statements referred to in Clause (A) 
          and any unaudited income statement data and balance sheet items 
          included in the Offering Circular and referred to in Clause (B) 
          were not determined on a basis substantially consistent 


<PAGE>

          with the basis for the audited consolidated financial statements 
          included in the Offering Circular;

               (D)  any unaudited pro forma consolidated condensed financial 
          statements included in the Offering Circular do not comply as to 
          form in all material respects with the applicable accounting 
          requirements or the pro forma adjustments have not been properly 
          applied to the historical amounts in the compilation of those 
          statements;

               (E)  as of a specified date not more than five days prior to 
          the date of such letter, there have been any changes in the 
          consolidated capital stock (other than issuances of capital stock 
          upon exercise of options and stock appreciation rights, upon 
          earn-outs of performance shares and upon conversions of convertible 
          securities, in each case which were outstanding on the date of the 
          latest financial statements included in the Offering Circular) or 
          any increase in the consolidated long-term debt of the Company and 
          its subsidiaries, or any decreases in consolidated net current 
          assets or stockholders' equity or other items specified by the 
          Purchaser, or any increases in any items specified by the 
          Purchaser, in each case as compared with amounts shown in the 
          latest balance sheet included in the Offering Circular except in 
          each case for changes, increases or decreases which the Offering 
          Circular discloses have occurred or may occur or which are 
          described in such letter; and

               (F)  for the period from the date of the latest financial 
          statements included in the Offering Circular to the specified date 
          referred to in Clause (E) there were any decreases in consolidated 
          operating revenues or operating income or the total or per share 
          amounts of consolidated net income or other items specified by the 
          Purchaser, or any increases in any items specified by the 
          Purchaser, in each case as compared with the comparable period of 
          the preceding year and with any other period of corresponding 
          length specified by the Purchaser, except in each case for 
          decreases or increases which the Offering Circular discloses have 
          occurred or may occur or which are described in such letter; and

          (v)  In addition to the examination referred to in their report(s) 
     included in the Offering Circular and the limited procedures, inspection 
     of minute books, inquiries and other procedures referred to in 
     paragraphs (iii) and (iv) above, they have carried out certain specified 
     procedures, not constituting an audit in accordance with generally 
     accepted auditing standards, with respect to certain amounts, 
     percentages and financial information specified by the Purchaser, which 
     are derived from the general accounting records of the Company and its 
     subsidiaries, which appear in the Offering Circular, and have compared 
     certain of such amounts, percentages and financial information with the 
     accounting records of the Company and its subsidiaries and have found 
     them to be in agreement.

record of Holders of Securities voting in favor thereof, either in person or by

delivered to the Trustee and, where it is hereby expressly required, to the
Company.  The Trustee shall promptly deliver to the Company copies of all such
instruments and records delivered to the Trustee.  Such instrument or
instruments and record (and the action embodied therein and evidenced thereby)

instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.

held by any Person, and the date of his holding the same, shall be proved by the
Security Register.



                                   -13-


<PAGE>

          (d)  The fact and date of execution of any such instrument or writing
and the authority of the Person executing the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section 1.4.

          (e)  The Company may set any day as the record date for the purpose of
determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted by this Indenture to be given or taken by
Holders.  Promptly and in any case not later than ten days after setting a
record date, the Company shall notify the Trustee and the Holders of such record
date.  If not set by the Company prior to the first solicitation of a Holder
made by any Person in respect of any such action, or, in the case of any such
vote, prior to such vote, the record date for any such action or vote shall be
the 30th day (or, if later, the date of the most recent list of Holders required
to be provided pursuant to Section 15.1) prior to such first solicitation or
vote, as the case may be.  With regard to any record date, the Holders on such
date (or their duly appointed agents or proxies), and only such Persons, shall
be entitled to give or take, or vote on, the relevant action, whether or not
such Holders remain Holders after such record date.  Notwithstanding the
foregoing, the Company shall not set a record date for, and the provisions of
this paragraph shall not apply with respect to, any notice, declaration or
direction referred to in the next paragraph.

          Upon receipt by the Trustee from any Holder of (i) any notice of
default or breach referred to in Section 5.1(4), if such default or breach has
occurred and is continuing and the Trustee shall not have given such a notice to
the Company, (ii) any declaration of acceleration referred to in Section 5.2, if
an Event of Default has occurred and is continuing and the Trustee shall not
have given such a declaration to the Company, or (iii) any direction referred to
in Section 5.12, if the Trustee shall not have taken the action specified in
such direction, then, with respect to clauses (ii) and (iii), a record date
shall automatically and without any action by the Company or the Trustee be set
for determining the Holders entitled to join in such declaration or direction,
which record date shall be the close of business on the tenth day (or, if such
day is not a Business Day, the first Business Day thereafter) following the day
on which the Trustee receives such declaration or direction, and, with respect
to clause (i), the Trustee may set any day as a record date for the purpose of
determining the Holders entitled to join in such notice of default.  Promptly
after such receipt by the Trustee of any such declaration or direction referred
to in clause (ii) or (iii), and promptly after setting any record date with
respect to clause (i), and as soon as practicable thereafter, the Trustee shall
notify the Company and the Holders of any such record date so fixed.  The
Holders on such record date (or their duly appointed agents or proxies), and
only such Persons, shall be entitled to join in such notice, declaration or
direction, whether or not such Holders remain Holders after such record date;
PROVIDED that, unless such notice, declaration or direction shall have become
effective by virtue of Holders of the requisite principal amount of Securities
on such record date (or their duly appointed agents or proxies) having joined
therein on or prior to the 90th day after such record date, such notice,
declaration or direction shall automatically and without any action by any
Person be cancelled 



                                   -14-

and of no further effect.  Nothing in this paragraph shall be construed to 
prevent a Holder (or a duly appointed agent or proxy thereof) from giving, 
before or after the expiration of such 90-day period, a notice, declaration 
or direction contrary to or different from, or, after the expiration of such 
period, identical to, the notice, declaration or direction to which such record
date relates, in which event a new record date in respect thereof shall be 
set pursuant to this paragraph.  In addition, nothing in this paragraph shall 
be construed to render ineffective any notice, declaration or direction of 
the type referred to in this paragraph given at any time to the Trustee and 
the Company by Holders (or their duly appointed agents or proxies) of the 
requisite principal amount of Securities on the date such notice, declaration 
or direction is so given.

          (f)  Except as provided in Sections 5.12 and 5.13, any request,
demand, authorization, direction, notice, consent, election, waiver or other Act
of the Holder of any Security shall bind every future Holder of the same
Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

          (g)  The provisions of this Section 1.4 are subject to the provisions
of Section 9.5.

SECTION 1.5.  NOTICES, ETC., TO TRUSTEE AND COMPANY.

     filed in writing to or with the Trustee and received at its Corporate Trust
     Office,  Attention:  Corporate Trust Department.

          (2)  the Company by the Trustee or by any Holder of Securities shall
     be sufficient for every purpose hereunder (unless otherwise herein
     expressly provided) if in writing, mailed, first-class postage prepaid, or
     telecopied and confirmed by mail, first-class postage prepaid, or delivered
     by hand or overnight courier, addressed to the Company at 2703 North

SECTION 1.6.  NOTICE TO HOLDERS OF SECURITIES; WAIVER.

          Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event, such notice shall be
sufficiently given to Holders if in writing and mailed, first-class postage
prepaid, to each Holder of a Security affected by such event, at the address of
such Holder as it appears in the Security Register, not earlier than the
earliest date and not later than the latest date prescribed for the giving of
such notice.

          Neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities.  In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification to Holders of Registered Securities as shall be made with
the approval of the Trustee, which approval shall not be unreasonably withheld,
shall constitute a sufficient notification to such Holders for every purpose
hereunder.

          Such notice shall be deemed to have been given when such notice is
mailed.

          Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

SECTION 1.7.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 1.13.  CONFLICT WITH TRUST INDENTURE ACT.

          If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.  Until such time as this Indenture shall be qualified under the Trust
Indenture Act, this Indenture, the Company and the Trustee shall be deemed for
all purposes hereof to be subject to and governed by the Trust Indenture Act to
the same extent as would be the case if this Indenture were so qualified on the
date hereof.

         This Security is one of a duly authorized issue of securities of the 
Company designated as its "5 1/2% Convertible Subordinated Notes due June 1, 
2001" (herein called the "Securities"), limited in aggregate principal amount 
to U.S.$126,500,000, issued and to be issued under an Indenture, dated as of 
May 28, 1996 (herein called the "Indenture"), between the Company and Bank of 
Montreal Trust Company, as Trustee (herein called the "Trustee", which term 
includes any successor trustee under the Indenture), to which Indenture and 
all indentures supplemental thereto reference is hereby made for a statement 
of the respective rights, limitations of rights, duties and immunities 
thereunder of the Company, the Trustee, the holders of Senior Indebtedness 
and the Holders of the Securities and of the terms upon which the Securities 
are, and are to be, authenticated and delivered.  As provided in the 
Indenture and subject to certain limitations therein set forth, Registered 
Securities are exchangeable for a like aggregate principal amount of 
Registered Securities of any authorized denominations as requested by the 
Holder surrendering the same upon surrender of the Registered Security or 
Registered Securities to be exchanged, at the Corporate Trust Office of the 
Trustee.  The Trustee upon such surrender by the Holder will issue the new 
Registered Securities in the requested denominations.

         No sinking fund is provided for the Securities.  The Securities are 
subject to redemption at the option of the Company at any time on or after 
June 1, 1999, in whole or in part, upon not less than 30 nor more than 60 
days' notice to the Holders prior to the Redemption Date at the following 
Redemption Prices (expressed as percentages of the principal amount) for the 
twelve-month period beginning on June 1 of the following years: 

                          Year         Redemption Price
                          ----         ----------------

                          1999              102.200
                          2000              101.100

and thereafter at a Redemption Price equal to 100% of the principal amount, 
together, in each case, with accrued interest to the Redemption Date; 
PROVIDED, HOWEVER, that interest installments on Registered Securities whose 
Stated Maturity is on or prior to such Redemption Date will be payable to the 
Holders of such Securities, or one or more Predecessor Securities, of record 
at the close of business on the relevant Record Dates referred to on the face 
hereof, all as provided in the Indenture.

         In the event of a redemption of the Securities, the Company will not 
be required (a) to register the transfer or exchange of Registered Securities 
for a period of 15 days immediately preceding the date notice is given 
identifying the serial numbers of the Securities 


                                       -26-


<PAGE>

called for such redemption or (b) to register the transfer or exchange of any 
Registered Security, or portion thereof, called for redemption.

         Notice to the Holders will be given not less than 30 nor more than 
60 days prior to the Redemption Date as provided in the Indenture.

         In any case where the due date for the payment of the principal of, 
premium, if any, interest, or Liquidated Damages on any Security or the last 
day on which a Holder of a Security has a right to convert his Security shall 
be, at any Place of Payment or Place of Conversion, as the case may be, a day 
on which banking institutions at such Place of Payment or Place of Conversion 
are authorized or obligated by law or executive order to close, then payment 
of principal, premium, if any, interest, or Liquidated Damages, or delivery 
for conversion of such Security need not be made on or by such date at such 
place but may be made on or by the next succeeding day at such place which is 
not a day on which banking institutions are authorized or obligated by law or 
executive order to close, with the same force and effect as if made on the 
date for such payment or the date fixed for redemption or repurchase, or by 
such last day for conversion, and no interest shall accrue on the amount so 
payable for the period after such date.

         Subject to and upon compliance with the provisions of the Indenture, 
the Holder of this Security is entitled, at his option, at any time on or 
after the 90th day following the last original issue date of the Securities 
and on or before the close of business on June 1, 2001, or in case this 
Security or a portion hereof is called for redemption or the Holder hereof 
has exercised his right to require the Company to repurchase this Security or 
such portion hereof, then in respect of this Security until and including, 
but (unless the Company defaults in making the payment due upon redemption or 
repurchase, as the case may be) not after, the close of business on the 
Redemption Date or the Repurchase Date, as the case may be, to convert this 
Security (or any portion of the principal amount hereof that is an integral 
multiple of U.S.$1,000, PROVIDED that the unconverted portion of such 
principal amount is U.S.$1,000 or any integral multiple of U.S.$1,000 in 
excess thereof) into fully paid and nonassessable shares of Common Stock of 
the Company at an initial Conversion Rate of 25.1572 (or at the current 
adjusted Conversion Rate if an adjustment has been made as provided in the 
Indenture) by surrender of this Security, duly endorsed or assigned to the 
Company or in blank and, in case such surrender shall be made during the 
period from the close of business on any Regular Record Date next preceding 
any Interest Payment Date to the opening of business on such Interest Payment 
Date (except if this Security has been called for redemption on a Redemption 
Date or is repurchasable on a Repurchase Date occurring, in either case, 
during such period and is surrendered for such conversion during such 
period), also accompanied by payment in New York Clearing House or other 
funds acceptable to the Company of an amount equal to the interest payable on 
such Interest Payment Date on the principal amount of this Security then 
being converted, and also the conversion notice hereon duly executed, to the 
Company at the Corporate Trust Office of the Trustee, or at such other office 
or agency of the Company, subject to any laws or regulations applicable 
thereto and subject to the right of the Company to terminate

portion hereof has been called for redemption on a Redemption Date or is 
repurchasable on a Repurchase Date occurring, in either case, during the 
period from the close of business on any Regular Record Date next preceding 
any Interest Payment Date to the opening of business on such succeeding 
Interest Payment Date and is surrendered for conversion during such period, 
then the Holder of this Security who converts this Security or a portion 
hereof during such period will be entitled to receive the interest accruing 
hereon from the Interest Payment Date next preceding the date of such 
conversion to such succeeding Interest Payment Date and shall not be required 
to pay such interest upon surrender of this Security for conversion.  Subject 
to the provisions of the preceding sentence and, in the case of a conversion 
after the close of business on the Regular Record Date next preceding any 
Interest Payment Date and on or before the close of business on such Interest 
Payment Date, to the right of the Holder of this Security (or any Predecessor 
Security of record as of such Regular Record Date) to receive the related 
installment of interest to the extent and under the circumstances provided in 
the Indenture, no cash payment or adjustment is to be made on conversion for 
interest accrued hereon from the Interest Payment Date next preceding the day 
of conversion, or for dividends on the Common Stock issued on conversion 
hereof.  The Company shall thereafter deliver to the Holder the fixed number 
of shares of Common Stock (together with any cash adjustment, as provided in 
the Indenture) into which this Security is convertible and such delivery will 
be deemed to satisfy the Company's obligation to pay the principal amount of 
this Security.  No fractions of shares or scrip representing fractions of 
shares will be issued on conversion, but instead of any fractional interest 
(calculated to the nearest 1/100th of a share) the Company shall pay a cash 
adjustment as provided in the Indenture.  The Conversion Rate is subject to 
adjustment as provided in the Indenture.  In addition, the Indenture provides 
that in case of certain consolidations or mergers to which the Company is a 
party or the conveyance, transfer, sale or lease of all or substantially all 
of the property and assets of the Company, the Indenture shall be amended, 
without the consent of any Holders of Securities, so that this Security, if 
then Outstanding, will be convertible thereafter, during the period this 
Security shall be convertible as specified above, only into the kind and 
amount of securities, cash and other property receivable upon such 
consolidation, merger, conveyance, transfer, sale or lease by a holder of the 
number of shares of Common Stock of the Company into which this Security 
could have been converted immediately prior to such consolidation, merger, 
conveyance, transfer, sale or lease (assuming such holder of Common Stock is 
not a Constituent Person, failed to exercise any rights of election and 
received per share the kind and amount received per share by a plurality of 
Non-electing Shares and further assuming, if such consolidation, merger, 
conveyance, transfer, sale or lease occurs prior to 90 days following the 
last original issue date of the Securities, that the Security was convertible 
at the time of such occurrence at the Conversion Rate specified above as 
adjusted from the issue date of such Security to such time as provided in the 
Indenture).  No adjustment in the Conversion Rate will be made until such 
adjustment would require an increase or decrease of at least one percent of 
such rate, PROVIDED that any adjustment that would otherwise be made will be 
carried forward and taken into account in the 


                                       -28-

computation of any subsequent adjustment.

         Subject to certain limitations in the Indenture, at any time when 
the Company is not subject to Section 13 or 15(d) of the United States 
Securities Exchange Act of 1934, as amended, upon the request of a Holder of 
a Restricted Security or the holder of shares of Common Stock issued upon 
conversion thereof, the Company will promptly furnish or cause to be 
furnished Rule 144A Information (as defined below) to such Holder of 
Restricted Securities or such holder of shares of Common Stock issued upon 
conversion of Restricted Securities, or to a prospective purchaser of any 
such security designated by any such Holder or holder, as the case may be, to 
the extent required to permit compliance by such Holder or holder with Rule 
144A under the Securities Act of 1933, as amended (the "Securities Act"), in 
connection with the resale of any such security. "Rule 144A Information" 
shall be such information as is specified pursuant to Rule 144A(d)(4) under 
the Securities Act (or any successor provision thereto).

         If this Security is a Registrable Security, then the Holder of this 
Security [IF THIS SECURITY IS A GLOBAL SECURITY, THEN INSERT-- (including any 
Person that has a beneficial interest in this Security)] and the Common Stock 
issuable upon conversion hereof is entitled to the benefits of a Registration 
Rights Agreement, dated as of May 28, 1996 (the "Registration Rights 
Agreement"), executed by the Company.  Pursuant to the Registration Rights 
Agreement, the Company has agreed for the benefit of the Holders from time to 
time of Registered Securities and the Common Stock issuable upon conversion 
thereof, in each case, that are Registrable Securities, at the Company's 
expense, (a) to file within 90 days after the first date of original issuance 
of the Securities, a shelf registration statement (the "Shelf Registration 
Statement") with the Commission with respect to resales of the Registrable 
Securities, (b) thereafter to use reasonable efforts to cause such Shelf 
Registration Statement to be declared effective by the Commission within 180 
days after the first date of original issuance of the Securities, and (c) to 
use reasonable efforts to maintain such Shelf Registration Statement 
continuously effective under the Securities Act until a period of the three 
years from the last date of original issuance of the Securities or, if 
earlier, until there are no outstanding Registrable Securities.

         Section 2(d) of the Registration Rights Agreement provides that, 
upon written notice to each Holder of a Registrable Security, the Company may 
postpone having the Shelf Registration Statement declared effective as 
required by Section 2(a) of the Registration Rights Agreement for a 
reasonable time specified in the notice but not exceeding 90 days if the 
Company is in possession of material non-public information the disclosure of 
which would have a material adverse effect on the business, operations, 
prospects, condition (financial or otherwise) of the Company and its 
subsidiaries, taken as a whole. Notwithstanding any postponement pursuant to 
Section 2(d) of the Registration Rights Agreement, if (i) on or prior to 90 
days following the date of original issuance of the Registered Securities, a 
Shelf Registration Statement has not been filed with the Commission, or (ii) 
on or prior to the 180th day following the date of original issuance of the 
Registered Securities, such Shelf Registration Statement is not declared 
effective (each, a "Registration Default"), additional interest 

                                       -29-

<PAGE>

("Liquidated Damages") will accrue on this Security from and including the 
day following such Registration Default to but excluding the day on which 
such Registration Default has been cured.  Liquidated Damages will be paid 
semi-annually in arrears, with the first semi-annual payment due on the first 
interest payment date in respect of the Registered Securities following the 
date on which such Liquidated Damages begin to accrue, and will accrue at a 
rate per annum equal to an additional one-quarter of one percent (.25%) of 
the principal amount of the Registered Securities to and including the 90th 
day following such Registration Default and at a rate per annum equal to 
one-half of one percent (.50%) thereof from and after the 91st day following 
such Registration Default.  In the event that the Shelf Registration 
Statement ceases to be effective prior to the third annual anniversary of the 
initial effective date of the Shelf Registration Statement or such earlier 
date as is provided in the Registration Rights Agreement for a period in 
excess of 60 days, whether or not consecutive, during any 12-month period, 
then the interest rate borne by the Registered Securities shall increase by 
an additional one-half of one percent (.50%) per annum from the 61st day of 
the applicable 12-month period such Shelf Registration Statement ceases to be 
effective to but excluding the day on which the Shelf Registration Statement 
again becomes effective.

         Whenever in this Security there is a reference, in any context, to 
the payment of the principal of, premium, if any, or interest on, or in 
respect of, any Security such mention shall be deemed to include mention of 
the payment of Liquidated Damages payable as described in the preceding 
paragraph to the extent that, in such context, Liquidated Damages are, were 
or would be payable in respect of this Security pursuant to such paragraph, 
and an express mention of the payment of Liquidated Damages (if applicable) 
in any provisions of this Security shall not be construed as excluding 
Liquidated Damages in those provisions of this Security where such express 
mention is not made.

         [If this Security is a Registrable Security and the Holder of this
Security [IF THIS SECURITY IS A GLOBAL SECURITY, THEN INSERT-- (including any
Person that has a beneficial interest in this Security)] elects to sell this
Security pursuant to the Shelf Registration Statement then, by its acceptance
hereof, such Holder of this Security agrees to be bound by the terms of the
Registration Rights Agreement relating to the Registrable Securities which are
the subject of such election.]

         If a Change in Control occurs, the Holder of this Security, at the 
Holder's option, shall have the right, in accordance with the provisions of 
the Indenture, to require the Company to repurchase this Security (or any 
portion of the principal amount hereof that is an integral multiple of 
$1,000, PROVIDED that the portion of the principal amount of this Security to 
be Outstanding after such repurchase is at least equal to U.S.$5,000) for 
cash at a Repurchase Price equal to 100% of the principal amount thereof plus 
interest accrued to the Repurchase Date.  At the option of the Company, the 
Repurchase Price may be paid in cash or, subject to the conditions provided 
in the Indenture, by delivery of shares of Common Stock having a fair market 
value equal to the Repurchase Price. For purposes of this paragraph, the fair 
market value of shares of Common Stock shall be determined by the Company and 
shall be equal to 


                                       -30-


<PAGE>

95% of the average of the Closing Prices Per Share for the five consecutive 
Trading Days immediately preceding the second Trading Day prior to the 
Repurchase Date.  Whenever in this Security there is a reference, in any 
context, to the principal of any Security as of any time, such reference 
shall be deemed to include reference to the Repurchase Price payable in 
respect of such Security to the extent that such Repurchase Price is, was or 
would be so payable at such time, and express mention of the Repurchase Price 
in any provision of this Security shall not be construed as excluding the 
Repurchase Price so payable in those provisions of this Security when such 
express mention is not made; PROVIDED, HOWEVER, that, for the purposes of the 
second succeeding paragraph, such reference shall be deemed to include 
reference to the Repurchase Price only to the extent the Repurchase Price is 
payable in cash.

         [THE FOLLOWING PARAGRAPH SHALL APPEAR IN EACH REGISTERED SECURITY THAT
IS NOT A GLOBAL SECURITY:

         In the event of redemption, repurchase or conversion of this 
Security in part only, a new Registered Security or Registered Securities for 
the unredeemed, unrepurchased or unconverted portion hereof will be issued in 
the name of the Holder hereof.]

         [THE FOLLOWING PARAGRAPH SHALL APPEAR IN EACH GLOBAL SECURITY:

         In the event of a deposit or withdrawal of an interest in this 
Security, including an exchange, transfer, redemption, repurchase or 
conversion of this Security in part only, the Trustee, as custodian of the 
Depositary, shall make an adjustment on its records to reflect such deposit 
or withdrawal in accordance with the Applicable Procedures.]

         The indebtedness evidenced by this Security is, to the extent and in 
the manner provided in the Indenture, subordinate and subject in right of 
payment to the prior payment in full of all Senior Indebtedness of the 
Company, and this Security is issued subject to such provisions of the 
Indenture with respect thereto.  Each Holder of this Security, by accepting 
the same, (a) agrees to and shall be bound by such provisions, (b) authorizes 
and directs the Trustee on his behalf to take such action as may be necessary 
or appropriate to effectuate the subordination so provided and (c) appoints 
the Trustee his attorney-in-fact for any and all such purposes.

         If an Event of Default shall occur and be continuing, the principal 
of all the Securities, together with accrued interest to the date of 
declaration, may be declared due and payable in the manner and with the 
effect provided in the Indenture.  Upon payment (i) of the amount of 
principal so declared due and payable, together with accrued interest to the 
date of declaration, and (ii) of interest on any overdue principal and, to 
the extent permitted by applicable law, overdue interest, all of the 
Company's obligations in respect of the payment of the principal of and 
interest on the Securities shall terminate.

         The Indenture permits, with certain exceptions as therein provided, 
the amendment 


                                       -31-


<PAGE>

thereof and the modification of the rights and obligations of the Company and 
the rights of the Holders of the Securities under the Indenture at any time 
by the Company and the Trustee with either (a) the written consent of the 
Holders of a majority in principal amount of the Securities at the time 
Outstanding, or (b) by the adoption of a resolution, at a meeting of Holders 
of the Outstanding Securities at which a quorum is present, by the Holders of 
66-2/3% in principal amount of the Outstanding Securities represented and 
entitled to vote at such meeting.  The Indenture also contains provisions 
permitting the Holders of specified percentages in principal amount of the 
Securities at the time Outstanding, on behalf of the Holders of all the 
Securities, to waive compliance by the Company with certain provisions of the 
Indenture and certain past defaults under the Indenture and their 
consequences.  Any such consent or waiver by the Holder of this Security 
shall be conclusive and binding upon such Holder and upon all future Holders 
of this Security and of any Security issued in exchange herefor or in lieu 
hereof, whether or not notation of such consent or waiver is made upon this 
Security or such other Security.

         As provided in and subject to the provisions of the Indenture, the 
Holder of this Security shall not have the right to institute any proceeding 
with respect to the Indenture or for the appointment of a receiver or trustee 
or for any other remedy thereunder, unless such Holder shall have previously 
given the Trustee written notice of a continuing Event of Default, the 
Holders of not less than 25% in principal amount of the Outstanding 
Securities shall have made written request to the Trustee to institute 
proceedings in respect of such Event of Default as Trustee and offered the 
Trustee reasonable indemnity and the Trustee shall not have received from the 
Holders of a majority in principal amount of the Securities Outstanding a 
direction inconsistent with such request, and shall have failed to institute 
any such proceeding, for 60 days after receipt of such notice, request and 
offer of indemnity.  The foregoing shall not apply to any suit instituted by 
the Holder of this Security for the enforcement of any payment of principal 
hereof, premium, if any, or interest hereon (including Liquidated Damages or 
additional interest) on or after the respective due dates expressed herein or 
for the enforcement of the right to convert this Security as provided in the 
Indenture.

         No reference herein to the Indenture and no provision of this 
Security or of the Indenture shall alter or impair the obligation of the 
Company, which is absolute and unconditional, to pay the principal of, 
premium, if any, and interest on (including Liquidated Damages and additional 
interest) this Security at the times, places and rate, and in the coin or 
currency, herein prescribed or to convert this Security as provided in the 
Indenture.

         As provided in the Indenture and subject to certain limitations 
therein set forth, the transfer of Registered Securities is registrable on 
the Security Register upon surrender of a Registered Security for 
registration of transfer at the Corporate Trust Office of the Trustee or at 
such other office or agency of the Company as may be designated by it for 
such purpose in the Borough of Manhattan, The City of New York, or at such 
other offices or agencies as the Company may designate, duly endorsed by, or 
accompanied by a written instrument of transfer in form satisfactory to the 
Company and the Security Registrar duly executed by, the Holder thereof or 
his attorney duly authorized in writing, and thereupon one or more new

Securities, of authorized denominations and for the same aggregate principal 
amount, will be issued to the designated transferee or transferees by the 
Registrar.  No service charge shall be made for any such registration of 
transfer or exchange, but the Company may require payment of a sum sufficient 
to recover any tax or other governmental charge payable in connection 
therewith.

         Prior to due presentation of a Registered 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 Registered Security is 
registered, as the owner thereof for all purposes, whether or not such 
Security be overdue, and neither the Company, the Trustee nor any such agent 
shall be affected by notice to the contrary.

         THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED 
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF 
AMERICA.

         All terms used in this Security which are defined in the Indenture

notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee or to its order for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with such Company Order shall authenticate and make available for
delivery such Securities as in this Indenture provided and not otherwise.

          Each Security shall be dated the date of its authentication.

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

SECTION 3.4.  GLOBAL SECURITIES; NON-GLOBAL SECURITIES.

    (A)   GLOBAL SECURITIES

          (a)  Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated by the Company for such
Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture.

          (b)  Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for 



                                   -38-


<PAGE>

such Global Security or a nominee thereof unless (i) such Depositary (A) has 
notified the Company that it is unwilling or unable to continue as Depositary 
for such Global Security or (B) has ceased to be a clearing agency registered 
as such under the Exchange Act or announces an intention permanently to cease 
business or does in fact do so or (ii) there shall have occurred and be 
continuing an Event of Default with respect to such Global Security.

          (c)  If any Global Security is to be exchanged for other Securities or
canceled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Trustee, as Security Registrar, for exchange or cancellation,
as provided in this Article Three.  If any Global Security is to be exchanged
for other Securities or cancelled in part, or if another Security is to be
exchanged in whole or in part for a beneficial interest in any Global Security,
in each case, as provided in Section 3.5, then either (i) such Global Security
shall be so surrendered for exchange or cancellation, as provided in this
Article Three, or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
cancelled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Trustee, as Security
Registrar, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records.  Upon any such surrender or adjustment
of a Global Security, the Trustee shall, subject to Section 3.5(c) and as
otherwise provided in this Article Three, authenticate and deliver any
Securities issuable in exchange for such Global Security (or any portion
thereof) to or upon the order of, and registered in such names as may be
directed by, the Depositary or its authorized representative.  Upon the request
of the Trustee in connection with the occurrence of any of the events specified
in the preceding paragraph, the Company shall promptly make available to the
Trustee a reasonable supply of Securities that are not in the form of Global
Securities.  The Trustee shall be entitled to rely upon any order, direction or
request of the Depositary or its authorized representative which is given or
made pursuant to this Article Three if such order, direction or request is given
or made in accordance with the Applicable Procedures.

          (d)  Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article Three or otherwise, shall be
authenticated and delivered in the form of, and shall be, a registered Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof, in which case such
Registered Security shall be authenticated and delivered in definitive, fully
registered form, without interest coupons.

          (e)  The Depositary or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under the
Indenture and the Registered Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only 



                                   -39-


<PAGE>

through, records maintained by the Depositary or its nominee or its Agent 
Members and such owners of beneficial interests in a Global Security will not 
be considered the owners or holders thereof.

     (B)  NON-GLOBAL SECURITIES

          Regulation D Securities shall be initially issued as Registered
Securities in definitive, fully registered form, without interest coupons, shall
initially be registered in such names and be in such authorized denominations as
Goldman, Sachs & Co. shall designate and shall bear the legends required
hereunder.  The Company will make available to the Trustee a reasonable supply
of Registered Securities in definitive form.

          Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Registered Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Registered
Securities may determine, as evidenced by their execution of such Securities.

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.2, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and make
available for delivery in exchange therefor a like principal amount of
definitive Securities of authorized denominations.  Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

SECTION 3.5.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE; RESTRICTIONS
              ON TRANSFER.

          (a)  The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency of the Company designated pursuant to Section 10.2 being
herein sometimes collectively referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Registered Securities and of transfers of
Registered Securities. The Trustee is hereby appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers and exchanges of
Registered Securities as herein provided.

          Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 10.2 for such
purpose, the Company shall 



                                   -40-


<PAGE>

execute, and the Trustee shall authenticate and deliver, in the name of the 
designated transferee or transferees, one or more new Securities of any 
authorized denominations and of a like aggregate principal amount and bearing 
such restrictive legends as may be required by this Indenture.

          At the option of the Holder, and subject to the other provisions of
this Section 3.5, Securities may be exchanged for other Securities of any
authorized denomination and of a like aggregate principal amount, upon surrender
of the Securities to be exchanged at any such office or agency.  Whenever any
Securities are so surrendered for exchange, and subject to the other provisions
of this Section 3.5, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.  Every Security presented or surrendered for registration
of transfer or for exchange shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and subject to the other provisions of this Section 3.5, entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
registration of transfer or exchange.

          No service charge shall be made for any registration of transfer or
exchange of Securities except as provided in Section 3.6, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Securities, other than exchanges pursuant to Section 3.4, 8.5, 11.8,
12.2 or 14.3 (other than where the shares of Common Stock are to be issued or
delivered in a name other than that of the Holder of the Security) not involving
any transfer and other than any stamp and other duties, if any, which may be
imposed in connection with any such transfer or exchange by the United States or
any political subdivision thereof or therein, which shall be paid by the
Company.

          In the event of a redemption of the Securities, the Company will not
be required (a) to register the transfer of or exchange Securities for a period
of 15 days immediately preceding the date notice is given identifying the serial
numbers of the Securities called for such redemption or (b) to register the
transfer of or exchange any Security, or portion thereof, called for redemption.

          (b)  CERTAIN TRANSFERS AND EXCHANGES.  Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 3.5(b) shall be made only in accordance with this Section 
3.5(b).




                                   -41-


<PAGE>

          (i)  RESTRICTED GLOBAL SECURITY TO REGULATION S GLOBAL SECURITY.
     If the owner of a beneficial interest in the Restricted Global Security
     wishes at any time to transfer such interest to a Person who wishes to
     acquire the same in the form of a beneficial interest in the Regulation S
     Global Security, such transfer may be effected only in accordance with the
     provisions of this Clause (b)(i) and Clause (b)(v) below and subject to the
     Applicable Procedures.  Upon receipt by the Trustee, as Security Registrar,
     of (A) an order given by the Depositary or its authorized representative
     directing that a beneficial interest in the Regulation S Global Security in
     a specified principal amount be credited to a specified Agent Member's
     account and that a beneficial interest in the Restricted Global Security in
     an equal principal amount be debited from another specified Agent Member's
     account and (B) a Regulation S Certificate, satisfactory to the Trustee and
     duly executed by the owner of such beneficial interest in the Restricted
     Global Security or his attorney duly authorized in writing, then the
     Trustee, as Security Registrar but subject to Clause (b)(v) below, shall
     reduce the principal amount of the Restricted Global Security and increase
     the principal amount of the Regulation S Global Security by such specified
     principal amount as provided in Section 3.4(A)(c).

          (ii)  REGULATION S GLOBAL SECURITY TO RESTRICTED GLOBAL SECURITY. 
     If the owner of a beneficial interest in the Regulation S Global Security
     wishes at any time to transfer such interest to a Person who wishes to
     acquire the same in the form of a beneficial interest in the Restricted
     Global Security, such transfer may be effected only in accordance with this
     Clause (b)(ii) and subject to the Applicable Procedures.  Upon receipt by
     the Trustee, as Security Registrar, of (A) an order given by the Depositary
     or its authorized representative directing that a beneficial interest in
     the Restricted Global Security in a specified principal amount be credited
     to a specified Agent Member's account and that a beneficial interest in the
     Regulation S Global Security in an equal principal amount be debited from
     another specified Agent Member's account and (B) if such transfer is to
     occur during the Restricted Period, a Restricted Securities Certificate,
     satisfactory to the Trustee and duly executed by the owner of such
     beneficial interest in the Regulation S Global Security or his attorney
     duly authorized in writing, then the Trustee, as Security Registrar, shall
     reduce the principal amount of the Regulation S Global Security and
     increase the principal amount of the Restricted Global Security by such
     specified principal amount as provided in Section 3.4(A)(c).

          (iii)  RESTRICTED NON-GLOBAL SECURITY TO RESTRICTED GLOBAL SECURITY
     OR REGULATION S GLOBAL SECURITY.  If the Holder of a Restricted Security
     (other than a Global Security) wishes at any time to transfer all or any
     portion of such Restricted Security to a Person who wishes to take
     delivery thereof in the form of a beneficial interest in the Restricted
     Global Security or the Regulation S Global Security, such transfer may be
     effected only in accordance with the provisions of this Clause (b)(iii) and
     Clause (b)(v) below and subject to the Applicable Procedures.  Upon receipt
     by the Trustee, as Security Registrar, of (A) such Restricted Security as
     provided in Section 3.5(a) and instructions satisfactory to the Trustee
     directing that a beneficial interest in the Restricted 



                                   -42-


<PAGE>

     Global Security or Regulation S Global Security in a specified principal
     amount not greater than the principal amount of such Security be credited
     to a specified Agent Member's account and (B) a Restricted Securities 
     Certificate, if the specified account is to be credited with a beneficial
     interest in the Restricted Global Security, or a Regulation S Certificate,
     if the specified account is to be credited with a beneficial interest in 
     the Regulation S Global Security, in either case satisfactory to the 
     Trustee and duly executed by such Holder or his attorney duly authorized 
     in writing, then the Trustee, as Security Registrar but subject to Clause 
     (b)(v) below, shall cancel such Restricted Security (and issue a new 
     Restricted Security in respect of any untransferred portion thereof) as 
     provided in Section 3.5(a) and increase the principal amount of the 
     Restricted Global Security or the Regulation S Global Security, as the case
     may be, by the specified principal amount as provided in Section 3.4(A)(c).

          (iv)  EXCHANGES BETWEEN GLOBAL SECURITY AND NON-GLOBAL SECURITY.  A
     beneficial interest in a Global Security may be exchanged for a Security
     that is not a Global Security as provided in Section 3.4, PROVIDED that, if
     such interest is a beneficial interest in the Restricted Global Security,
     or if such interest is a beneficial interest in the Regulation S Global
     Security and such exchange is to occur during the Restricted Period, then
     such interest shall be exchanged for a Restricted Security (subject in each
     case to Section 3.5(c)).  A Security that is not a Global Security may be
     exchanged for a beneficial interest in a Global Security only if (A) such
     exchange occurs in connection with a transfer effected in accordance with
     Clause (b)(iii) above.

          (v)  REGULATION S GLOBAL SECURITY TO BE HELD THROUGH EUROCLEAR OR
     CEDEL DURING RESTRICTED PERIOD.  The Company shall use its best efforts to
     cause the Depositary to ensure that, until the expiration of the Restricted
     Period, beneficial interests in the Regulation S Global Security may be
     held only in or through accounts maintained at the Depositary by Euroclear
     or CEDEL (or by Agent Members acting for the account thereof), and no
     person shall be entitled to effect any transfer or exchange that would
     result in any such interest being held otherwise than in or through such an
     account; PROVIDED that this Clause (b)(v) shall not prohibit any transfer
     or exchange of such an interest in accordance with Clause (b)(ii) or (iv)
     above.

          (c)  SECURITIES ACT LEGENDS.  Rule 144A Securities, Regulation D
Securities and their respective Successor Securities shall bear the applicable
Restricted Securities Legend, and the Regulation S Securities and their
Successor Securities shall bear a Regulation S Legend, subject to the following:

             (i)  subject to the following Clauses of this Section 3.5(c), a
    Security or any portion thereof which is exchanged, upon transfer or
    otherwise, for a Global Security or any portion thereof shall bear the
    Securities Act Legend borne by such Global Security while represented
    thereby;



                                   -43-

<PAGE>

           (ii)  subject to the following Clauses of this Section 3.5(c), a new
    Security which is not a Global Security and is issued in exchange for
    another Security (including a Global Security) or any portion thereof, upon
    transfer or otherwise, shall bear the Securities Act Legend borne by such
    other Security, PROVIDED that, if such new Security is required pursuant to
    Section 3.5(b)(iv) to be issued in the form of a Restricted Security, it
    shall bear a Restricted Securities Legend and, if such new Security is so
    required to be issued in the form of a Regulation S Security, it shall bear
    a Regulation S Legend;

          (iii)  any Securities which are sold or otherwise disposed of
    pursuant to an effective registration statement under the Securities Act
    (including the Shelf Registration Statement), together with their Successor
    Securities shall not bear a Securities Act Legend; the Company shall inform
    the Trustee in writing of the effective date of any such registration
    statement registering the Securities under the Securities Act and shall
    notify the Trustee at any time when prospectuses may not be delivered with
    respect to Securities to be sold pursuant to such registration statement.
    The Trustee shall not be liable for any action taken or omitted to be taken
    by it in good faith in accordance with the aforementioned registration
    statement;

           (iv)  at any time after the Securities may be freely transferred
    without registration under the Securities Act or without being subject to
    transfer restrictions pursuant to the Securities Act, a new Security which
    does not bear a Securities Act Legend may be issued in exchange for or in
    lieu of a Security (other than a Global Security) or any portion thereof
    which bears such a legend if the Trustee has received an Unrestricted
    Securities Certificate, satisfactory to the Trustee and duly executed by
    the Holder of such legended Security or his attorney duly authorized in
    writing, and after such date and receipt of such certificate, the Trustee
    shall authenticate and deliver such a new Security in exchange for or in
    lieu of such other Security as provided in this Article Three;

            (v)  a new Security which does not bear a Securities Act Legend may
    be issued in exchange for or in lieu of a Security (other than a Global
    Security) or any portion thereof which bears such a legend if, in the
    Company's judgment, placing such a legend upon such new Security is not
    necessary to ensure compliance with the registration requirements of the
    Securities Act, and the Trustee, at the direction of the Company, shall
    authenticate and deliver such a new Security as provided in this Article
    Three; and

           (vi)  notwithstanding the foregoing provisions of this Section
    3.5(c), a Successor Security of a Security that does not bear a particular
    form of Securities Act Legend shall not bear such form of legend unless the
    Company has reasonable cause to believe that such Successor Security is a
    "restricted security" within the meaning of Rule 144, in which case the
    Trustee, at the direction of the Company, shall authenticate and deliver 

                                  -44-


<PAGE>

    a new Security bearing a Restricted Securities Legend in exchange for such
    Successor Security as provided in this Article Three.

         (d)  Neither the Trustee, the Paying Agent nor any of their agents
shall (1) have any duty to monitor compliance with or with respect to any
federal or state or other securities or tax laws or (2) have any duty to obtain
documentation on any transfers or exchanges other than as specifically required
hereunder.  

SECTION 3.6.  MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there be delivered to the Company and to the Trustee:

         (1) evidence to their satisfaction of the destruction, loss or theft
    of any Security, and

         (2) such security or indemnity as may be satisfactory to the Company
    and the Trustee to save each of them and any agent of either of them
    harmless,

then, in the absence of actual notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security, upon satisfaction of the conditions set forth in the preceding
paragraph.

         Upon the issuance of any new Security under this Section 3.6, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto (other than any
stamp and other duties, if any, which may be imposed in connection therewith by
the United States or any political subdivision thereof or therein, which shall
be paid by the Company) and any other expenses (including the fees and expenses
of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section 3.6 in lieu of any
mutilated, destroyed, lost or stolen Security  shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any 


                                  -45-


<PAGE>


time enforceable by anyone, and such new Security shall be entitled to all 
the benefits of this Indenture equally and proportionately with any and all 
other Securities duly issued hereunder.

         The provisions of this Section 3.6 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies of any Holder with respect
to the replacement or payment of mutilated, destroyed, lost or stolen
Securities.

SECTION 3.7.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

         (1)  The Company may elect to make payment of any Defaulted Interest
    to the Persons in whose names the Securities (or their respective
    Predecessor Securities) are registered at the close of business on a
    Special Record Date for the payment of such Defaulted Interest, which shall
    be fixed in the following manner.  The Company shall notify the Trustee in
    writing of the amount of Defaulted Interest proposed to be paid on each
    Security, the date of the proposed payment and the Special Record Date, and
    at the same time the Company shall deposit with the Trustee an amount of
    money equal to the aggregate amount proposed to be paid in respect of such
    Defaulted Interest or shall make arrangements satisfactory to the Trustee
    for such deposit prior to the date of the proposed payment, such money when
    deposited to be held in trust for the benefit of the Persons entitled to
    such Defaulted Interest as in this Clause provided.  The Special Record
    Date for the payment of such Defaulted Interest shall be not more than 15
    days and not less than 10 days prior to the date of the proposed payment
    and not less than 10 days after the receipt by the Trustee of the notice of
    the proposed payment.  The Trustee, in the name and at the expense of the
    Company, shall cause notice of the proposed payment of such Defaulted
    Interest and the Special Record Date therefor to be mailed, first-class
    postage prepaid, to each Holder at such Holder's address as it appears in
    the Security Register, not less than 10 days prior to such Special Record
    Date.  Notice of the proposed payment of such Defaulted Interest and the
    Special Record Date therefor having been so mailed, such Defaulted Interest
    shall be paid to the Persons in whose names the Securities (or their
    respective Predecessor Securities) are registered at the close of business
    on such Special Record Date and shall no longer be payable pursuant to the
    following Clause (2).

                                  -46-


<PAGE>


         (2)  The Company may make payment of any Defaulted Interest in any
    other lawful manner not inconsistent with the requirements of any
    securities exchange on which the Securities may be listed, and upon such
    notice as may be required by such exchange, if, after notice given by the
    Company to the Trustee of the proposed payment pursuant to this Clause,
    such manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 3.5,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         Interest on any Security which is converted in accordance with Section
12.2 during a Record Date Period shall be payable in accordance with the
provisions of Section 12.2.

SECTION 3.8.  PERSONS DEEMED OWNERS.

         Prior to due presentment of a 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 Security is registered as the owner of such
Security for the purpose of receiving payment of principal of, premium, if any,
and (subject to Section 3.7) interest on such Security and for all other
purposes whatsoever, whether or not such 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 3.9.  CANCELLATION.

         All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee.  All Securities so
delivered to the Trustee shall be canceled promptly by the Trustee.  No
Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section 3.9.  The Trustee shall dispose of all
canceled Securities in accordance with applicable law and its customary
practices in effect from time to time.

SECTION 3.10. COMPUTATION OF INTEREST.

         Interest on the Securities (including any Liquidated Damages and
additional interest) shall be computed on the basis of a 360-day year of twelve
30-day months.

SECTION 3.11. [RESERVED].

                                  -47-


<PAGE>


SECTION 3.12. CUSIP NUMBERS.

         The Company in issuing Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers, if so, the Trustee shall use
such CUSIP numbers in addition to serial numbers in notices of redemption and
repurchase as a convenience to Holders; PROVIDED that any such notice may state
that no representation is made as to the correctness of such CUSIP numbers
either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Securities, and any such redemption

              (B)   all such Securities not theretofore delivered to the
         Trustee or its agent for cancellation (other than Securities referred
         to in clauses (i) and (ii) of clause (1)(A) above) 

                   (i)  have become due and payable, or 

                   (ii)  will have become due and payable at their Stated

         entire indebtedness on such Securities not theretofore delivered to
         the Trustee for cancellation, for principal, premium, if any, and

         interest (including any Liquidated Damages) to the date of such
         deposit (in the case of Securities which have become due and payable)
         or to the Stated Maturity or Redemption Date, as the case may be;

         (2)  the Company has paid or caused to be paid all other sums payable
    hereunder by the Company; and

         (3)  the Company has delivered to the Trustee an Officers' Certificate
    and an Opinion of Counsel, each stating that all conditions precedent
    herein provided for relating to the satisfaction and discharge of this
    Indenture have been complied with.

thereto, of the principal, premium, if any, and interest for whose payment such
money has been deposited with the Trustee.

         All moneys deposited with the Trustee pursuant to Section 4.1 (and
held by it or any Paying Agent) for the payment of Securities subsequently

    Trustee by the Holders of at least 10% in principal amount of the
    Outstanding Securities a written notice specifying such default or breach
    and requiring it to be remedied and stating that such notice is a "Notice
    of Default" hereunder; PROVIDED, HOWEVER, that if such default or breach is
    capable of being cured and the Company commences efforts to cure such
    default or breach within such 60 day period, such default or breach shall
    not be considered an "Event of Default" hereunder for an additional 60 days
    so long as the Company is diligently pursuing the cure; or

         (5)  a default under any bond, debenture, note or other evidence of
    indebtedness for money borrowed by the Company or under any mortgage,

    Company with a principal amount then outstanding in excess of
    U.S.$10,000,000, whether such indebtedness now exists or shall hereafter be
    created, which default shall have resulted in such indebtedness becoming or
    being declared due and payable prior to the date on which it would
    otherwise have 

                                    -51-

    period of 30 days after there shall have been given, by registered or 
    certified mail, to the Company by the Trustee or to the Company and the
    Trustee by the Holders of at least 10% in principal amount of the
    Outstanding Securities a written notice specifying such default and
    requiring the Company to cause such indebtedness to be discharged or cause
    such default to be cured or waived or such acceleration to be rescinded or
    annulled and stating that such notice is a "Notice of Default" hereunder;
    or

         (6)  the entry by a court having jurisdiction in the premises of (A) a
    decree or order for relief in respect of the Company in an involuntary case
    or proceeding under any applicable Federal or State bankruptcy, insolvency,
    reorganization or other similar law or (B) a decree or order adjudging the
    Company a bankrupt or insolvent, or approving as properly filed a petition
    seeking reorganization, arrangement, adjustment or composition of or in

    part of its property, or ordering the winding up or liquidation of its
    affairs, and the continuance of any such decree or order for relief or any
    such other decree or order unstayed and in effect for a period of 60
    consecutive days; or

    insolvency, reorganization or other similar law or to the commencement of
    any bankruptcy or insolvency case or proceeding against it, or the filing
    by it of a petition or answer or consent seeking reorganization or similar
    relief under any applicable Federal or State law, or the consent by it to
    the filing of such petition or to the appointment of or taking possession
    by a custodian, receiver, liquidator, assignee, trustee, sequestrator or
    other similar official of the Company or of any substantial part of its
    property, or the making by it of an assignment for the benefit of
    creditors, or the admission by it in writing of its inability to pay its
    debts generally as they become due, or the taking of corporate action by
    the Company in furtherance of any such action.

SECTION 5.2.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 5.1(6) or 5.1(7)) occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities may, subject to the provisions of Article Thirteen,
declare the principal of all the Securities to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by the
Holders), and upon 


                                    -52-


<PAGE>




any such declaration such principal and all accrued interest thereon shall 
become immediately due and payable.  If an Event of Default specified in 
Section 5.1(6) or 5.1(7) occurs, the principal of, and accrued interest on, 
all the Securities shall, subject to the provisions of Article Thirteen, IPSO 
FACTO become immediately due and payable without any declaration or other Act 
of the Holder or any act on the part of the Trustee.

         At any time after such declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article Five provided, the Holders of a
majority in principal amount of the Outstanding Securities, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if

         (1)  the Company has paid or deposited with the Trustee a sum
    sufficient to pay

              (A)  all overdue interest on all Securities,

              (B)  the principal of and premium, if any, on any Securities
         which have become due otherwise than by such declaration of
         acceleration and any interest thereon at the rate borne by the
         Securities,

              (C)  to the extent permitted by applicable law, interest upon
         overdue interest at a rate of 51/2% per annum, and

              (D)  all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel;

    and

         (2)  all Events of Default, other than the nonpayment of the principal
    of, and any premium and interest on, Securities which have become due
    solely by such declaration of acceleration, have been cured or waived as
    provided in Section 5.13.

         No rescission or annulment referred to above shall affect any
subsequent default or impair any right consequent thereon.

SECTION 5.3.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

         (1)  default is made in the payment of any interest (including any
    Liquidated Damages) on any Security when it becomes due and payable and
    such default continues for a period of 30 days, or

                                    -53-


<PAGE>


         (2)  default is made in the payment of the principal of or premium, if
    any, on any Security at the Maturity thereof,

the Company will, upon demand of the Trustee but subject to the provisions of
Article Thirteen, pay to it, for the benefit of the Holders of such Securities
the whole amount then due and payable on such Securities for principal and
interest (including any Liquidated Damages) and interest on any overdue
principal and premium, if any, and, to the extent permitted by applicable law,
on any overdue interest (including any Liquidated Damages), at a rate of 51/2%
per annum, and in addition thereto, such further amount as shall be sufficient
to cover the reasonable costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

SECTION 5.4.  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or the
creditors of either, the Trustee (irrespective of whether the principal of, and
any interest on, the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of overdue principal
or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise, 

         (1)  to file and prove a claim for the whole amount of principal,
    premium, if any, and interest owing and unpaid in respect of the Securities
    and take such other actions, including participating as a member, voting or
    otherwise, of any official committee of creditors appointed in such matter,
    and to file such other papers or documents, in each of the foregoing cases,
    as may be necessary or advisable in order to have the claims of 


                                    -54-


<PAGE>


    the Trustee (including any claim for the reasonable compensation, expenses,
    disbursements and advances of the Trustee, its agents and counsel) and of
    the Holders of Securities allowed in such judicial proceeding, and 

         (2)  to collect and receive any moneys or other property payable or
    deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders of Securities to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and any other amounts due the Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder of a Security in any such proceeding;
PROVIDED, HOWEVER, that the Trustee may, on behalf of such Holders, vote for the
election of a trustee in bankruptcy or similar official.

SECTION 5.5.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION
              OF SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which judgment
has been recovered.

SECTION 5.6.  APPLICATION OF MONEY COLLECTED.

         Subject to Article Thirteen, any money collected by the Trustee
pursuant to this Article Five shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal, premium, if any, or interest, upon presentation
of the Securities and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

         FIRST: To the payment of all amounts due the Trustee under Section 6.7;

                                     -55-

<PAGE>

         SECOND:  To the payment of the amounts then due and unpaid for
    principal of, premium, if any, or interest on, the Securities in respect of
    which or for the benefit of which such money has been collected, ratably,
    without preference or priority of any kind, according to the amounts due
    and payable on such Securities for principal, premium, if any, and
    interest, respectively; and

         THIRD:  Any remaining amounts shall be repaid to the Company.

SECTION 5.7.  LIMITATION ON SUITS.

         No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

         (1)  such Holder has previously given written notice to the Trustee of
    a continuing Event of Default;

         (2)  the Holders of not less than 25% in principal amount of the
    Outstanding Securities shall have made written request to the Trustee to
    institute proceedings in respect of such Event of Default in its own name
    as Trustee hereunder;

         (3)  such Holder or Holders have offered to the Trustee reasonable
    indemnity against the costs, expenses and liabilities to be incurred in
    compliance with such request;

         (4)  the Trustee for 60 days after its receipt of such notice, request
    and offer of indemnity has failed to institute any such proceeding; and

         (5)  no direction inconsistent with such written request has been
    given to the Trustee during such 60-day period by the Holders of a majority
    in principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

                                    -56-


<PAGE>


SECTION 5.8.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
              INTEREST AND TO CONVERT.

         Notwithstanding any other provision in this Indenture, but subject to
the provisions of Article Thirteen, the Holder of any Security shall have the
right, which is absolute and unconditional, to receive payment of the principal
of, premium, if any, and (subject to Section 3.7) interest on such Security on
the respective Stated Maturities expressed in such Security (or, in the case of
redemption or repurchase, on the Redemption Date or Repurchase Date, as the case
may be), and to convert such Security in accordance with Article Twelve, and to
institute suit for the enforcement of any such payment and right to convert, and
such rights shall not be impaired without the consent of such Holder.

SECTION 5.9.  RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder of a Security has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and such Holders shall continue as though no such proceeding had been
instituted.

SECTION 5.10. RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

SECTION 5.11. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
any acquiescence therein.  Every right and remedy given by this Article Five or
by law to the Trustee or to the Holders of Securities may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or (subject to
the limitations contained in this Indenture) by the Holders of Securities as the
case may be.


                                    -57-

SECTION 5.12. CONTROL BY HOLDERS OF SECURITIES.

         The Holders of a majority in principal amount of the Outstanding
Securities shall 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, PROVIDED that

         (1)  such direction shall not be in conflict with any rule of law or
    with this Indenture, and

         (2)  the Trustee may take any other action deemed proper by the
    Trustee which is not inconsistent with such direction.

SECTION 5.13. WAIVER OF PAST DEFAULTS.

         The Holders, either (a) through the written consent of not less than a
majority in principal amount of the Outstanding Securities, or (b) by the
adoption of a resolution, at a meeting of Holders of the Outstanding Securities
at which a quorum is present, by the Holders of at least 66-2/3% in principal
amount of the Outstanding Securities represented at such meeting, may on behalf
of the Holders of all the Securities waive any past default hereunder and its
consequences, except a default (1) in the payment of the principal of, premium,
if any, or interest on any Security, or (2) in respect of a covenant or
provision hereof which under Article Eight cannot be modified or amended without
the consent of the Holder of each Outstanding Security affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 5.14. UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.14 shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities, or to any suit instituted by any Holder of
any Security for the enforcement of the payment of the principal of, premium, if
any, or interest on any Security on or after the respective Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption or
repurchase, on or after the Redemption Date or Repurchase Date, as the case 

                                    -58-

may be) or for the enforcement of the right to convert any Security in 
accordance with Article Twelve.

SECTION 5.15. WAIVER OF STAY, USURY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay, usury or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede by reason of such law the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

SECTION 6.1.  CERTAIN DUTIES AND RESPONSIBILITIES.

         (a)  Except during the continuance of an Event of Default,

         (1)  the Trustee undertakes to perform such duties and only such
    duties as are specifically set forth in this Indenture, and no implied

    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed therein, upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture; but in
    the case of any such certificates or opinions which by any provision hereof
    are specifically required to be furnished to the Trustee, the Trustee shall
    be under a duty to examine the same to determine whether or not they
    conform to the requirements of this Indenture, but not to verify the
    contents thereof.

         (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

         (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, EXCEPT that

         (1)  this paragraph (c) shall not be construed to limit the effect of
    paragraph (a) of this Section;

         (2)  the Trustee shall not be liable for any error of judgment made in
    good faith by a Responsible Officer, unless it shall be proved that the
    Trustee was negligent in ascertaining the pertinent facts;

                                    -60-

         (3)  the Trustee shall not be liable with respect to any action taken
    or omitted to be taken by it in good faith in accordance with the direction
    of the Holders of a majority in principal amount of the Outstanding
    Securities relating to the time, method and place of conducting any
    proceeding for any remedy available to the Trustee, or exercising any trust
    or power conferred upon the Trustee, under this Indenture; and

         (4)  no provision of this Indenture shall require the Trustee to
    expend or risk its own funds or otherwise incur any financial liability in
    the performance of any of its duties hereunder, or in the exercise of any
    of its rights or powers, if it shall have reasonable grounds for believing
    that repayment of such funds or adequate indemnity against such risk or
    liability is not reasonably assured to it.

         (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

SECTION 6.2.  NOTICE OF DEFAULTS.

         Within 90 days after the occurrence of any default hereunder as to
which the Trustee has received written notice, the Trustee shall give to all
Holders of Securities, in the manner provided in Section 1.6, notice of such
default, unless such default shall have been cured or waived; PROVIDED, HOWEVER,
that, except in the case of a default in the payment of the principal of,
premium, if any, or interest on any Security the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
interest of the Holders; and PROVIDED, FURTHER, that in the case of any default
of the character specified in Section 5.1(4), no such notice to Holders of
Securities shall be given until at least 60 days after the occurrence thereof
or, if applicable, the cure period specified therein.  For the purpose of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default.

SECTION 6.3.  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 6.1:

         (5)  the Trustee shall be under no obligation to exercise any of the
    rights or powers vested in it by this Indenture at the request or direction
    of any of the Holders of Securities pursuant to this Indenture, unless such
    Holders shall have offered to the Trustee reasonable security or indemnity
    against the costs, expenses and liabilities which might be incurred by it
    in compliance with such request or direction;

         (6)  the Trustee shall not be bound to make any investigation into the

         (7)  the Trustee may execute any of the trusts or powers hereunder or
    perform any duties hereunder either directly or by or through agents or

         The Trustee, any Authenticating Agent, any Paying Agent, any
Conversion Agent or any other agent of the Company or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
and may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Authenticating Agent, Paying Agent, Conversion Agent or such
other agent.

         The Trustee may become and act as trustee under other indentures under
which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder.

SECTION 6.6.  MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated

under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

SECTION 6.7.  COMPENSATION AND REIMBURSEMENT.

         The Company agrees

         (1)  to pay to the Trustee from time to time such compensation as the

    express trust);

         (2)  except as otherwise expressly provided herein, to reimburse the
    Trustee upon its request for all reasonable expenses, disbursements and

    disbursement or advance as may be attributable to its negligence or bad
    faith; and

         (3)  to indemnify the Trustee (and its directors, officers, employees

    including the reasonable costs, expenses and reasonable attorneys' fees of
    defending itself against any claim or liability in connection with the
    exercise or performance of any of its powers or duties hereunder.

                                    -63-


<PAGE>


         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(6) or Section 5.1(7), the
expenses (including the reasonable charges of its counsel) and the compensation
for the services are intended to constitute expenses of the administration under
any applicable Federal or state bankruptcy, insolvency or other similar law.

         The provisions of this Section shall survive the termination of this
Indenture or the earlier resignation or removal of the Trustee.

SECTION 6.8.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such,
having a combined capital and surplus of at least U.S.$10,000,000 in the case of
the initial Trustee hereunder and US$50,000,000 in the case of any successor
Trustee, subject to supervision or examination by federal or state authority, in
good standing and having an established place of business in the Borough of
Manhattan, The City of New York.  If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published.  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article and a
successor shall be appointed pursuant to Section 6.9.

SECTION 6.9.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.10.

         (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 6.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the
Trustee and the Company.  If the instrument of acceptance by a successor Trustee
required by Section 6.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of removal, the removed Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

                                    -64-


<PAGE>


         (d)  If at any time:

         (1)  the Trustee shall cease to be eligible under Section 6.8 and
    shall fail to resign after written request therefor by the Company or by
    any Holder of a Security who has been a bona fide Holder of a Security for
    at least six months, or 

         (2)  the Trustee shall become incapable of acting or shall be adjudged
    a bankrupt or insolvent or a receiver of the Trustee or of its property
    shall be appointed or any public officer shall take charge or control of
    the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.14, any Holder of a Security who has been
a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

         (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee and
shall comply with the applicable requirements of this Section and Section 6.10. 
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.10, become the successor Trustee
and supersede the successor Trustee appointed by the Company.  If no successor
Trustee shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner required by this Section and Section
6.10, any Holder of a Security who has been a bona fide Holder of a Security for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders of Securities in the manner provided in Section 1.6.  Each notice shall
include the name of the successor Trustee and the address of its Corporate Trust
Office.

SECTION 6.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the 

                                    -65-


<PAGE>



rights, powers, trusts and duties of the retiring Trustee; but, on the 
request of the Company or the successor Trustee, such retiring Trustee shall, 
upon payment of its charges, execute and deliver an instrument transferring 
to such successor Trustee all the rights, powers and trusts of the retiring 
Trustee and shall duly assign, transfer and deliver to such successor Trustee 
all property and money held by such retiring Trustee hereunder.  Upon request 
of any such successor Trustee, the Company shall execute any and all 
instruments for more fully and certainly vesting in and confirming to such 
successor Trustee all such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be eligible under this Article.

SECTION 6.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
PROVIDED such corporation shall be otherwise eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.12. AUTHENTICATING AGENTS.

         The Trustee may, with the consent of the Company, appoint an
Authenticating Agent or Agents acceptable to the Company with respect to the
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities issued upon exchange or substitution pursuant to this
Indenture.  

         Securities authenticated by an Authenticating Agent shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder, and every reference in
this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee's certificate of authentication shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.  Each Authenticating Agent shall be subject to acceptance
by the Company and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent and subject to supervision or examination by government or other fiscal
authority.  If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of 

                                    -66-


<PAGE>


this Section 6.12, such Authenticating Agent shall resign immediately in the 
manner and with the effect specified in this Section 6.12.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, PROVIDED such corporation shall be otherwise eligible
under this Section 6.12, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.12, the Trustee may appoint a successor
Authenticating Agent which shall be subject to acceptance by the Company.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent. 
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 6.12.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 6.12.

         If an Authenticating Agent is appointed with respect to the Securities
pursuant to this Section 6.12, the Securities may have endorsed thereon, in
addition to or in lieu of the Trustee's certification of authentication, an
alternative certificate of authentication in the following form:

         This is one of the Securities referred to in the within-mentioned
Indenture.

SECTION 6.13. DISQUALIFICATION; CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

SECTION 6.14. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

verified by the affidavits of the permanent chairman and secretary of the
meeting and one such copy shall be delivered to the Company and another to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting.  Any record so signed and verified shall be

Trustee or such Paying Agent with respect to such trust money, and all 
liability of the Company as trustee thereof, shall thereupon cease; PROVIDED, 
HOWEVER, that the Trustee or such Paying Agent, before being required to make

from an "affiliate" of the Company within the meaning of Rule 144 under the 
Securities Act (or any successor provision thereto).  "Rule 144A Information" 
shall be such information as is specified pursuant to Rule 144A(d)(4) under 
the Securities Act (or any successor provision thereto).

SECTION 10.11.  RESALE OF CERTAIN SECURITIES; REPORTING ISSUER.

         During the period beginning on the last date of original issuance of

SECTION 10.12.  REGISTRATION RIGHTS.

         The Company agrees that the Holders from time to time of Registrable 
Securities (as defined below) are entitled to the benefits of a Registration 
Rights Agreement, dated as of May 28, 1996 (the "Registration Rights 
Agreement"), executed by the Company. Pursuant to the Registration Rights 
Agreement, the Company has agreed for the benefit of the Holders from time to 
time of Registrable Securities, at the Company's expense, (i) to file within 
90 days after the first date of original issuance of the Securities, a shelf 
registration statement (the "Shelf Registration Statement") with the 
Commission with respect to resales of the Registrable Securities, (ii)

to be declared effective by the Commission within 180 days after the first 
date of original issuance of the Securities, and (iii) to use reasonable 
efforts to maintain such Shelf Registration Statement 


                                       -82-


<PAGE>

continuously effective under the Securities Act of 1933, as amended, until a 
period of three years from the last date of original issuance of the 
Securities or, if earlier, until there are no outstanding Registrable 
Securities.

         Section 2(d) of the Registration Rights Agreement provides that, 
upon written notice to each Holder of a Registrable Security, the Company may 
postpone having the Shelf Registration Statement declared effective as 
required by Section 2(a) of the Registration Rights Agreement for a 
reasonable time specified in the notice but not exceeding 90 days if the 
Company is in possession of material non-public information the disclosure of 
which would have a material adverse effect on the business, operations, 
prospects, condition (financial or otherwise) of the Company and its 
subsidiaries, taken as a whole. Notwithstanding any postponement pursuant to 
Section 2(d) of the Registration Rights Agreement, if (i) on or prior to 90 
days following the date of original issuance of the Registered Securities, a 
Shelf Registration Statement has not been filed with the Commission, or (ii) 
on or prior to the 180th day following the date of original issuance of the 
Registered Securities, such Shelf Registration Statement is not declared 
effective (each, a "Registration Default"), additional interest ("Liquidated 
Damages") will accrue on the Registered Securities from and including the day 
following such Registration Default to but excluding the day on which such 
Registration Default has been cured. Liquidated Damages will be paid 
semi-annually in arrears, with the first semi-annual payment due on the first 
Interest Payment Date in respect of the Registered Securities following the 
date on which such Liquidated Damages begin to accrue, and will accrue at a 
rate per annum equal to an additional one-quarter of one percent (.25%) of 
the principal amount of the Registered Securities to and including the 90th 
day following such Registration Default and at a rate per annum equal to 
one-half of one percent (.50%) thereof from and after the 91st day following 
such Registration Default. In the event that the Shelf Registration Statement 
ceases to be effective prior to the third annual anniversary of the initial 
effective date of the Shelf Registration Statement or such earlier date as is 
provided in the Registration Rights Agreement for a period in excess of 60 
days, whether or not consecutive, during any 12-month period, then the 
interest rate borne by the Registered Securities shall increase by an 
additional one-half of one percent (.50%) per annum on the 61st day of the 
applicable 12-month period such Shelf Registration Statement ceases to be 
effective to but excluding the day on which the Shelf Registration Statement 
again becomes effective.

         Whenever in this Indenture there is mentioned, in any context, the 
payment of the principal of, premium, if any, or interest on, or in respect 
of, any Registered Security, such mention shall be deemed to include mention 
of the payment of Liquidated Damages provided for in this Section to the 
extent that, in such context, Liquidated Damages are, were or would be 
payable in respect thereof pursuant to the provisions of this Section, and 
express mention of the payment of Liquidated Damages (if applicable) in any 
provisions hereof shall not be construed as excluding Liquidated Damages in 
those provisions hereof where such express mention is not made.

         For the purposes of the Registration Rights Agreement, "Registrable 
Securities" means all or any portion of the Registered Securities issued from 
time to time under this Indenture and the shares of Common Stock issuable 
upon conversion of such Securities  PROVIDED, HOWEVER, that a Security or the 
shares of Common Stock issuable upon conversion of a Security ceases to be a 
Registrable Security when it (i) has been effectively registered under the 
Securities Act and sold in a manner contemplated by the Shelf Registration 
Statement, (ii) has been transferred in compliance with Rule 144 under the 
Securities Act (or any successor provisions thereto) or (iii) otherwise has 
been transferred and a new Security or share of Common Stock not subject to 
transfer restrictions under the Securities Act has been delivered by or on 
behalf of the Company in accordance with Section 3.5(b).

         If a Security, or the shares of Common Stock issuable upon 
conversion of a Security, is a Registrable Security, and the Holder thereof 
elects to sell such Registrable Security pursuant to the Shelf Registration 
Statement then, by its acceptance thereof, the Holder of such Registrable 
Security will have agreed to be bound by the terms of the Registration Rights 
Agreement relating to the Registrable Securities which are the subject of 
such election.

         For the purposes of the Registration Rights Agreement, the term 
"Holder" includes any Person that has a beneficial interest in any Global 
Security or any beneficial interest in a global security representing shares 
of Common Stock issuable upon conversion of a Security. 

SECTION 10.13.  WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any 
covenant or conditions set forth in Sections 10.5 to 10.7, inclusive (other 
than a covenant or condition which under Article Eight cannot be modified or 
amended without the consent of the Holder of each Outstanding Security 
affected), if before the time for such compliance the Holders shall, through 
the written consent of, or the adoption of a resolution at a meeting of 
Holders of the Outstanding Securities at which a quorum is present by, not 
less than a majority in principal amount of the Outstanding Securities, 
either waive such compliance in such instance or generally waive compliance 
with such covenant or condition, but no such waiver shall extend to or affect 
such covenant or condition except to the extent so expressly waived, and, 
until such waiver shall become effective, the obligations of the Company and 
the duties of the Trustee or any Paying or Conversion Agent in respect of any 
such covenant or condition shall remain in full force and effect.

SECTION 11.1. RIGHT OF REDEMPTION.

         The Securities may be redeemed in accordance with the provisions of 
the form of Securities set forth in Section 2.2.

SECTION 11.2. APPLICABILITY OF ARTICLE.

         Redemption of Securities at the election of the Company or 
otherwise, as permitted or required by any provision of the Securities or 
this Indenture, shall be made in accordance with such provision and this 
Article Eleven.

SECTION 11.3. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be 
evidenced by a Board Resolution.  In case of any redemption at the election 
of the Company of any of the Securities, the Company shall, at least 60 days 
prior to the Redemption Date fixed by the Company (unless a shorter notice 
shall be satisfactory to the Trustee), notify the Trustee in writing of such 
Redemption Date.  If the Securities are to be redeemed pursuant to an 
election of the Company which is subject to a condition specified in the form 
of Securities set forth in Section 2.2, the Company shall furnish the Trustee 
with an Officers' Certificate stating that the Company is entitled to effect 
such redemption and setting forth a statement of facts showing that the 
conditions precedent to the right of the Company so to redeem have occurred.

SECTION 11.4. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities are to be redeemed, the particular 
Securities to be redeemed shall be selected by the Trustee within two 
Business Days after it receives the notice described in 11.3, from  the 
Outstanding Securities not previously called for redemption, by such method 
as the Trustee may deem fair and appropriate.

         If any Registered Security selected for partial redemption is 
converted in part before termination of the conversion right with respect to 
the portion of the Security so selected, the converted portion of such 
Security shall be deemed (so far as may be) to be the portion selected for 
redemption. Securities which have been converted during a selection of 
Securities to be redeemed may be treated by the Trustee as Outstanding for 
the purpose of such selection.

         The Trustee shall promptly notify the Company and each Security 
Registrar in 


                                       -85-


<PAGE>

writing of the securities selected for redemption and, in the case of any 
Securities selected for partial redemption, the principal amount thereof to 
be redeemed.

         For all purposes of this Indenture, unless the context otherwise 
requires, all provisions relating to the redemption of Securities shall 
relate, in the case of any Securities redeemed or to be redeemed only in 
part, to the portion of the principal amount of such Securities which has 
been or is to be redeemed.

SECTION 11.5. NOTICE OF REDEMPTION.

         Notice of redemption shall be given in the manner provided in 
Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor 
more than 60 days prior to the Redemption Date, and such notice shall be 
irrevocable.

         All notices of redemption shall state:

         (1)  the Redemption Date,

         (2)  the Redemption Price, and accrued interest, if any,

         (3)  if less than all Outstanding Securities are to be redeemed, the
    aggregate principal amount of Securities to be redeemed and the aggregate
    principal amount of Securities which will be outstanding after such partial
    redemption,

         (4)  that on the Redemption Date the Redemption Price, and accrued
    interest, if any, will become due and payable upon each such Security to be
    redeemed, and that interest thereon shall cease to accrue on and after said
    date,

         (5)  the Conversion Rate, the date on which the right to convert the
    Securities to be redeemed will terminate and the places where such
    Securities, may be surrendered for conversion, and

         (6)  the place or places where such Securities, are to be surrendered
    for payment of the Redemption Price and accrued interest, if any.

         In case of a partial redemption, the first notice given shall 
specify the last date on which exchanges or transfers of Securities may be 
made pursuant to Section 3.5 and the second notice shall specify the serial 
and CUSIP numbers (if any) and the portions thereof called for redemption.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's written request,

                                       -86-


<PAGE>

the election of the Company received by the Trustee shall be given by the 
Trustee to each Paying Agent in the name of and at the expense of the Company.

SECTION 11.6. DEPOSIT OF REDEMPTION PRICE.

         Not less than one Business Day prior to any Redemption Date, the 
Company shall deposit with the Trustee (or, if the Company is acting as its 
own Paying Agent, segregate and hold in trust as provided in Section 10.3) an 
amount of money (which shall be in immediately available funds on such 
Redemption Date) sufficient to pay the Redemption Price of, and (except if 
the Redemption Date shall be an Interest Payment Date) accrued interest on, 
all the Securities which are to be redeemed on that date other than any 
Securities called for redemption on that date which have been converted prior 
to the date of such deposit.

         If any Security called for redemption is converted, any money 
deposited with the Trustee or so segregated and held in trust for the 
redemption of such Security shall (subject to any right of the Holder of such 
Security or any Predecessor Security to receive interest as provided in the 
last paragraph of Section 3.7) be paid to the Company on Company Request or, 
if then held by the Company, shall be discharged from such trust.

SECTION 11.7. SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities 
so to be redeemed shall, on the Redemption Date, become due and payable at 
the Redemption Price therein specified and from and after such date (unless 
the Company shall default in the payment of the Redemption Price, including 
accrued interest) such Securities shall cease to bear interest.  Upon 
surrender of any Security for redemption in accordance with said notice such 
Security shall be paid by the Company at the Redemption Price together with 
accrued and unpaid interest to the Redemption Date; PROVIDED, HOWEVER, that 
installments of interest on Securities whose Stated Maturity is on or prior 
to the Redemption Date shall be payable to the Holders of such Securities, or 
one or more Predecessor Securities, registered as such on the relevant Record 
Date according to their terms and the provisions of Section 3.7.

         If any Security called for redemption shall not be so paid upon 
surrender thereof for redemption, the principal amount of, premium, if any, 
and, to the extent permitted by applicable law, accrued interest on such 
Security shall, until paid, bear interest from the Redemption Date at a rate 
of 5 1/2% per annum and such Security shall remain convertible until the 
principal of such Security (or portion thereof, as the case may be) shall 
have been paid or duly provided for.

SECTION 11.8. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be 
surrendered at an office or agency of the Company designated for that purpose 
pursuant to Section 10.2 (with, if the Company or the Trustee so requires, 
due endorsement by, or a written instrument of transfer 


                                       -87-


<PAGE>

in form satisfactory to the Company and the Trustee duly executed by, the 
Holder thereof or his attorney duly authorized in writing), and the Company 
shall execute, and the Trustee shall authenticate and make available for 
delivery to the Holder of such Security without service charge, a new 
Registered Security or Securities, of any authorized denomination as 
requested by such Holder, in aggregate principal amount equal to and in 
exchange for the unredeemed portion of the principal of the Security so 
surrendered.

                                    ARTICLE TWELVE

                               CONVERSION OF SECURITIES

SECTION 12.1. CONVERSION PRIVILEGE AND CONVERSION RATE.

         Subject to and upon compliance with the provisions of this Article, 
at the option of the Holder thereof, any Security may be converted into fully 
paid and nonassessable shares (calculated as to each conversion to the 
nearest 1/100th of a share) of Common Stock of the Company at the Conversion 
Rate, determined as hereinafter provided, in effect at the time of 
conversion.  Such conversion right shall commence on the 90th day after the 
last original issuance date of the Securities and expire at the close of 
business on June 1, 2001, subject, in the case of conversion of any Global 
Security, to any Applicable Procedures.  In case a Security or portion 
thereof is called for redemption at the election of the Company or the Holder 
thereof exercises his right to require the Company to repurchase the 
Security, such conversion right in respect of the Security, or portion 
thereof so called, shall expire at the close of business on the Redemption 
Date or the Repurchase Date, as the case may be, unless the Company defaults 
in making the payment due upon redemption or repurchase, as the case may be 
(in each case subject as aforesaid to any Applicable Procedures with respect 
to any Global Security).

         The rate at which shares of Common Stock shall be delivered upon 
conversion (herein called the "Conversion Rate") shall be initially 25.1572 
shares of Common Stock for each U.S.$1,000 principal amount of Securities.  
The Conversion Rate shall be adjusted in certain instances as provided in 
this Article Twelve.

SECTION 12.2. EXERCISE OF CONVERSION PRIVILEGE.

         In order to exercise the conversion privilege, the Holder of any 
Security to be converted shall surrender such Security, duly endorsed or 
assigned to the Company or in blank, at any office or agency of the Company 
maintained for that purpose pursuant to Section 10.2, accompanied by a duly 
signed conversion notice substantially in the form set forth in Section 2.5 
stating that the Holder elects to convert such Security or, if less than the 
entire principal amount thereof is to be converted, the portion thereof to be 
converted.  Each Security surrendered for conversion (in whole or in part) 
during the period from the close of business on any Regular Record Date next 
preceding any Interest Payment Date to the opening of business on such 
Interest Payment Date shall (except in the case of any Security or portion 
thereof which has been called for redemption on a Redemption Date, or is 
repurchasable on a Repurchase Date, occurring, in either case, within such 
period) be accompanied by payment in New York Clearing House funds or other 
funds acceptable to the Company of an amount equal to the interest payable on 
such Interest Payment Date on the principal amount of such Security (or part 
thereof, as the case may be) being surrendered for conversion.  The interest 
so payable on such Interest Payment Date with respect to any Security (or 
portion thereof, if applicable) which has been 


                                       -89-


<PAGE>

called for redemption on a Redemption Date, or is repurchasable on a 
Repurchase Date, occurring, in either case, during the period from the close 
of business on any Record Date next preceding any Interest Payment Date to 
the opening of business on such Interest Payment Date, which Security (or 
portion thereof, if applicable) is surrendered for conversion during such 
period, shall be paid to the Holder of such Security being converted in an 
amount equal to the interest that would have been payable on such Security if 
such Security had been converted as of the close of business on such Interest 
Payment Date.  The interest so payable on such Interest Payment Date in 
respect of any Security (or portion thereof, as the case may be) which has 
not been called for redemption on a Redemption Date, or is not eligible for 
repurchase on a Repurchase Date, occurring, in either case, during the period 
from the close of business on any Record Date next preceding any Interest 
Payment Date to the opening of business on such Interest Payment Date, which 
Security (or portion thereof, as the case may be) is surrendered for 
conversion during such period, shall be paid to the Holder of such Security 
as of such Regular Record Date. Interest payable in respect of any Security 
surrendered for conversion on or after an Interest Payment Date shall be paid 
to the Holder of such Security as of the next preceding Regular Record Date, 
notwithstanding the exercise of the right of conversion.  Except as provided 
in this paragraph and subject to the last paragraph of Section 3.7, no cash 
payment or adjustment shall be made upon any conversion on account of any 
interest accrued from the Interest Payment Date next preceding the conversion 
date, in respect of any Security (or part thereof, as the case may be) 
surrendered for conversion, or on account of any dividends on the Common 
Stock issued upon conversion.  The Company's delivery to the Holder of the 
number of shares of Common Stock (and cash in lieu of fractions thereof, as 
provided in this Indenture) into which a Security is convertible will be 
deemed to satisfy the Company's obligation to pay the principal amount of the 
Security.

         Securities shall be deemed to have been converted immediately prior 
to the close of business on the day of surrender of such Securities for 
conversion in accordance with the foregoing provisions, and at such time the 
rights of the Holders of such Securities as Holders shall cease, and the 
Person or Persons entitled to receive the Common Stock issuable upon 
conversion shall be treated for all purposes as the record holder or holders 
of such Common Stock at such time.  As promptly as practicable on or after 
the conversion date, the Company shall issue and deliver to the Trustee, for 
delivery to the Holder, a certificate or certificates for the number of full 
shares of Common Stock issuable upon conversion, together with payment in 
lieu of any fraction of a share, as provided in Section 12.3.

         All shares of Common Stock delivered upon such conversion of 
Restricted Securities shall bear restrictive legends substantially in the 
form of the legends required to be set forth on the Restricted Securities 
pursuant to Section 3.5 and shall be subject to the restrictions on transfer 
provided in such legends.  Neither the Trustee nor any agent maintained for 
the purpose of such conversion shall have any responsibility for the 
inclusion or content of any such restrictive legends on such Common Stock; 
PROVIDED, HOWEVER, that the Trustee or any agent maintained for the purpose 
of such conversion shall have provided, to the Company or to the Company's 
transfer agent for such Common Stock, prior to or concurrently with a request 


                                       -90-


<PAGE>


to the Company to deliver such Common Stock, written notice that the 
Securities delivered for conversion are Restricted Securities.

         In the case of any Security which is converted in part only, upon 
such conversion the Company shall execute and the Trustee shall authenticate 
and deliver to the Holder thereof, at the expense of the Company, a new 
Registered Security or Securities of authorized denominations in an aggregate 
principal amount equal to the unconverted portion of the principal amount of 
such Security.  A Security may be converted in part, but only if the 
principal amount of such Security to be converted is any integral multiple of 
U.S.$1,000 and the principal amount of such security to remain Outstanding 
after such conversion is equal to U.S.$1,000 or any integral multiple of 
$1,000 in excess thereof.

         If shares of Common Stock to be issued upon conversion of a 
Restricted Security, or Registered Securities to be issued upon conversion of 
a Restricted Security in part only, are to be registered in a name other than 
that of the beneficial owner of such Restricted Security, then such Holder 
must deliver to the Conversion Agent a Surrender Certificate, dated the date 
of surrender of such Restricted Security and signed by such beneficial owner, 
as to compliance with the restrictions on transfer applicable to such 
Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar 
or Transfer Agent shall be required to register in a name other than that of 
the beneficial owner, shares of Common Stock or Securities issued upon 
conversion of any such Restricted Security not so accompanied by a properly 
completed Surrender Certificate.

SECTION 12.3. FRACTIONS OF SHARES.

         No fractional shares of Common Stock shall be issued upon conversion 
of any Security or Securities.  If more than one Security shall be 
surrendered for conversion at one time by the same Holder, the number of full 
shares which shall be issuable upon conversion thereof shall be computed on 
the basis of the aggregate principal amount of the Securities (or specified 
portions thereof) so surrendered.  Instead of any fractional share of Common 
Stock which would otherwise be issuable upon conversion of any Security or 
Securities (or specified portions thereof), the Company shall calculate and 
pay a cash adjustment in respect of such fraction (calculated to the nearest 
1/100th of a share) in an amount equal to the same fraction of the Closing 
Price Per Share at the close of business on the day of conversion.

SECTION 12.4. ADJUSTMENT OF CONVERSION RATE.

         The Conversion Rate shall be subject to adjustments from time to 
time as follows:

         (1)  In case the Company shall pay or make a dividend or other
distribution on any class of capital stock of the Company payable in shares of
Common Stock, the Conversion Rate in effect at the opening of business on the
day following the date fixed for the determination of shareholders entitled to
receive such dividend or other distribution shall be 


                                       -91-


<PAGE>

increased by dividing such Conversion Rate by a fraction of which the 
numerator shall be the number of shares of Common Stock outstanding at the 
close of business on the date fixed for such determination and the 
denominator shall be the sum of such number of shares and the total number of 
shares constituting such dividend or other distribution, such increase to 
become effective immediately after the opening of business on the day 
following the date fixed for such determination.  If, after any such date 
fixed for determination, any dividend or distribution is not in fact paid, 
the Conversion Rate shall be immediately readjusted, effective as of the date 
the Board of Directors determines not to pay such dividend or distribution, 
to the Conversion Rate that would have been in effect if such determination 
date had not been fixed.  For the purposes of this paragraph (1), the number 
of shares of Common Stock at any time outstanding shall not include shares 
held in the treasury of the Company but shall include shares issuable in 
respect of scrip certificates issued in lieu of fractions of shares of Common 
Stock.  The Company will not pay any dividend or make any distribution on 
shares of Common Stock held in the treasury of the Company.

         (2)  In case the Company shall issue rights, options or warrants to 
all holders of its Common Stock entitling them to subscribe for or purchase 
shares of Common Stock at a price per share less than the current market 
price per share (determined as provided in paragraph (8) of this Section 
12.4) of the Common Stock on the date fixed for the determination of 
stockholders entitled to receive such rights, options or warrants (other than 
any rights, options or warrants that by their terms will also be issued to 
any Holder upon conversion of a Security into shares of Common Stock without 
any action required by the Company or any other Person), the Conversion Rate 
in effect at the opening of business on the day following the date fixed for 
such determination shall be increased by dividing such Conversion Rate by a 
fraction of which the numerator shall be the number of shares of Common Stock 
outstanding at the close of business on the date fixed for such determination 
plus the number of shares of Common Stock which the aggregate of the offering 
price of the total number of shares of Common Stock so offered for 
subscription or purchase would purchase at such current market price and the 
denominator shall be the number of shares of Common Stock outstanding at the 
close of business on the date fixed for such determination plus the number of 
shares of Common Stock so offered for subscription or purchase, such increase 
to become effective immediately after the opening of business on the day 
following the date fixed for such determination.  If, after any such date 
fixed for determination, any such rights, options or warrants are not in fact 
issued, the Conversion Rate shall be immediately readjusted, effective as of 
the date the Board of Directors determines not to issue such rights, options 
or warrants, to the Conversion Rate that would have been in effect if such 
determination date had not been fixed. For the purposes of this paragraph 
(2), the number of shares of Common Stock at any time outstanding shall not 
include shares held in the treasury of the Company but shall include shares 
issuable in respect of scrip certificates issued in lieu of fractions of 
shares of Common Stock.  The Company will not issue any rights, options or 
warrants in respect of shares of Common Stock held in the treasury of the 
Company.


                                       -92-


<PAGE>

         (3)  In case outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Rate in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately increased, and,
conversely, in case outstanding shares of Common Stock shall each be combined
into a smaller number of shares of Common Stock, the Conversion Rate in effect
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or
reduction, as the case may be, to become effective immediately after the opening
of business on the day following the day upon which such subdivision or
combination becomes effective.

         (4)  In case the Company shall, by dividend or otherwise, distribute
to all holders of its Common Stock evidences of its indebtedness, shares of any
class of capital stock, or other property (including securities, but excluding
(i) any rights, options or warrants referred to in paragraph (2) of this
Section, (ii) any dividend or distribution paid exclusively in cash, (iii) any
dividend or distribution referred to in paragraph (1) of this Section and (iv)
any merger or consolidation to which Section 12.11 applies), the Conversion Rate
shall be adjusted so that the same shall equal the rate determined by dividing
the Conversion Rate in effect immediately prior to the close of business on the
date fixed for the determination of stockholders entitled to receive such
distribution by a fraction of which the numerator shall be the current market
price per share (determined as provided in paragraph (8) of this Section 12.4)
of the Common Stock on the date fixed for such determination less the then fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution filed with the Trustee) of the
portion of the assets, shares or evidences of indebtedness so distributed
applicable to one share of Common Stock and the denominator shall be such
current market price per share of the Common Stock, such adjustment to become
effective immediately prior to the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
distribution.  If, after any such date fixed for determination, any such
distribution is not in fact made, the Conversion Rate shall be immediately
readjusted, effective as of the date the Board of Directors determines not to
make such distribution, to the Conversion Rate that would have been in effect if
such determination date had not been fixed.

         (5) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock cash (excluding any cash that is distributed
upon a merger or consolidation to which Section 12.11 applies or as part of a
distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with (I) the aggregate amount of any other cash
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no adjustment pursuant to this paragraph (5) has been made and (II) the
aggregate of any cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) of consideration payable in respect of any tender offer by the
Company or any of its subsidiaries for all or any portion of the Common Stock
concluded within the 12 months preceding the date of payment of such
distribution and in respect of which no adjustment pursuant to paragraph (6) of
this Section 12.4 has been made (the 


                                     -93-


<PAGE>


"combined cash and tender amount") exceeds 10% of the product of the current 
market price per share (determined as provided in paragraph (8) of this 
Section 12.4) of the Common Stock on the date for the determination of 
holders of shares of Common Stock entitled to receive such distribution times 
the number of shares of Common Stock outstanding on such date (the "aggregate 
current market price"), then, and in each such case, immediately after the 
close of business on such date for determination, the Conversion Rate shall 
be adjusted so that the same shall equal the rate determined by dividing the 
Conversion Rate in effect immediately prior to the close of business on the 
date fixed for determination of the stockholders entitled to receive such 
distribution by a fraction (i) the numerator of which shall be equal to the 
current market price per share (determined as provided in paragraph (8) of 
this Section) of the Common Stock on the date fixed for such determination 
less an amount equal to the quotient of (x) the excess of such combined cash 
and tender amount over such aggregate current market price divided by (y) the 
number of shares of Common Stock outstanding on such date for determination 
and (ii) the denominator of which shall be equal to the current market price 
per share (determined as provided in paragraph (8) of this Section 12.4) of 
the Common Stock on such date for determination.

         (6) In case a tender offer made by the Company or any Subsidiary for
all or any portion of the Common Stock shall expire and such tender offer (as
amended upon the expiration thereof) shall require the payment to stockholders
(based on the acceptance (up to any maximum specified in the terms of the tender
offer) of Purchased Shares (as defined below)) of an aggregate consideration
having a fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution) that
combined together with (I) the aggregate of the cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution), as of the expiration of such
tender offer, of consideration payable in respect of any other tender offer by
the Company or any Subsidiary for all or any portion of the Common Stock
expiring within the 12 months preceding the expiration of such tender offer and
in respect of which no adjustment pursuant to this paragraph (6) has been made
and (II) the aggregate amount of any cash distributions to all holders of the
Company's Common Stock within 12 months preceding the expiration of such tender
offer and in respect of which no adjustment pursuant to paragraph (5) of this
Section has been made (the "combined tender and cash amount") exceeds 10% of the
product of the current market price per share of the Common Stock (determined as
provided in paragraph (8) of this Section 12.4) as of the last time (the
"Expiration Time") tenders could have been made pursuant to such tender offer
(as it may be amended) times the number of shares of Common Stock outstanding
(including any tendered shares) as of the Expiration Time, then, and in each
such case, immediately prior to the opening of business on the day after the
date of the Expiration Time, the Conversion Rate shall be adjusted so that the
same shall equal the rate determined by dividing the Conversion Rate immediately
prior to close of business on the date of the Expiration Time by a fraction (i)
the numerator of which shall be equal to (A) the product of (I) the current
market price per share of the Common Stock (determined as provided in paragraph
(8) of this Section 12.4) on the date of the Expiration Time multiplied by (II)
the number of shares of Common Stock outstanding (including any tendered shares)
on the 


                                     -94-


<PAGE>

Expiration Time less (B) the combined tender and cash amount, and (ii) the 
denominator of which shall be equal to the product of (A) the current market 
price per share of the Common Stock (determined as provided in paragraph (8) 
of this Section 12.4) as of the Expiration Time multiplied by (B) the number 
of shares of Common Stock outstanding (including any tendered shares) as of 
the Expiration Time less the number of all shares validly tendered and not 
withdrawn as of the Expiration Time (the shares deemed so accepted up to any 
such maximum, being referred to as the "Purchased Shares").

         (7)  The reclassification of Common Stock into securities including
other than Common Stock (other than any reclassification upon a consolidation or
merger to which Section 12.11 applies) shall be deemed to involve (a) a
distribution of such securities other than Common Stock to all holders of Common
Stock (and the effective date of such reclassification shall be deemed to be
"the date fixed for the determination of stockholders entitled to receive such
distribution" and "the date fixed for such determination" within the meaning of
paragraph (4) of this Section), and (b) a subdivision or combination, as the
case may be, of the number of shares of Common Stock outstanding immediately
prior to such reclassification into the number of shares of Common Stock
outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be "the day upon which such subdivision
becomes effective" or "the day upon which such combination becomes effective",
as the case may be, and "the day upon which such subdivision or combination
becomes effective" within the meaning of paragraph (3) of this Section 12.4).

         (8)  For the purpose of any computation under paragraphs (2), (4), (5)
or (6) of this Section 12.4, the current market price per share of Common Stock
on any date shall be calculated by the Company and be deemed to be the average
of the daily Closing Prices Per Share for the five consecutive Trading Days
selected by the Company commencing not more than 10 Trading Days before, and
ending not later than, the earlier of the day in question and the day before the
"ex" date with respect to the issuance or distribution requiring such
computation.  For purposes of this paragraph, the term " ex' date", when used
with respect to any issuance or distribution, means the first date on which the
Common Stock trades regular way in the applicable securities market or on the
applicable securities exchange without the right to receive such issuance or
distribution.

         (9)  No adjustment in the Conversion Rate shall be required unless
such adjustment (plus any adjustments not previously made by reason of this
paragraph (9)) would require an increase or decrease of at least one percent in
such rate; PROVIDED, HOWEVER, that any adjustments which by reason of this
paragraph (9) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.  All calculations under this Article
shall be made to the nearest cent or to the nearest one-hundredth of a share, as
the case may be.

         (10)  The Company may make such increases in the Conversion Rate, for
the remaining term of the Securities or any shorter term, in addition to those
required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 12.4, as
it considers to be advisable in order to 


                                     -95-


<PAGE>

avoid or diminish any income tax to any holders of shares of Common Stock 
resulting from any dividend or distribution of stock or issuance of rights or 
warrants to purchase or subscribe for stock or from any event treated as such 
for income tax purposes.  The Company shall have the power to resolve any 
ambiguity or correct any error in this paragraph (10) and its actions in so 
doing shall, absent manifest error, be final and conclusive.

         (11)  Notwithstanding the foregoing provisions of this Section, no
adjustment of the Conversion Rate shall be required to be made (a) upon the
issuance of shares of Common Stock pursuant to any present or future plan for
the reinvestment of dividends or (b) because of a tender or exchange offer of
the character described in Rule 13e-4(h)(5) under the Exchange Act or any
successor rule thereto.

SECTION 12.5. NOTICE OF ADJUSTMENTS OF CONVERSION RATE.

         Whenever the Conversion Rate is adjusted as herein provided:

         (1)  the Company shall compute the adjusted Conversion Rate in
    accordance with Section 12.4 and shall prepare a certificate signed by the
    Chief Financial Officer of the Company setting forth the adjusted
    Conversion Rate and showing in reasonable detail the facts upon which such
    adjustment is based, and such certificate shall promptly be filed with the
    Trustee and with each Conversion Agent; and

         (2)  upon each such adjustment, a notice stating that the Conversion
    Rate has been adjusted and setting forth the adjusted Conversion Rate shall
    be required, and as soon as practicable after it is required, such notice
    shall be provided by the Company to all Holders in accordance with Section
    1.6.

Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours.

SECTION 12.6. NOTICE OF CERTAIN CORPORATE ACTION.

         In case:

         (a) the Company shall declare a dividend (or any other distribution)
    on its Common Stock payable (i) otherwise than exclusively in cash or (ii)
    exclusively in cash in an amount that would require any adjustment pursuant
    to Section 12.4; or

         (b) the Company shall authorize the granting to the holders of its
    Common 


                                     -96-


<PAGE>


    Stock of rights, options or warrants to subscribe for or purchase any 
    shares of capital stock of any class or of any other rights; or

         (c) of any reclassification of the Common Stock of the Company, or of
    any consolidation, merger or share exchange to which the Company is a party
    and for which approval of any stockholders of the Company is required, or
    of the conveyance, sale, transfer or lease of all or substantially all of
    the assets of the Company; or

         (d) of the voluntary or involuntary dissolution, liquidation or
    winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.2, and shall
cause to be provided to all Holders in accordance with Section 1.6, at least 20
days (or 10 days in any case specified in clause (a) or (b) above) prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights, options or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to
such dividend, distribution, rights, options or warrants are to be determined or
(y) the date on which such reclassification, consolidation, merger, conveyance,
transfer, sale, lease, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, sale, lease, dissolution,
liquidation or winding up.  Neither the failure to give such notice or the
notice referred to in the following paragraph nor any defect therein shall
affect the legality or validity of the proceedings described in clauses (a)
through (d) of this Section 12.6.  If at the time the Trustee shall not be the
conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

         The Company shall cause to be filed at each office or agency
maintained for the purpose of conversion of Securities pursuant to Section 10.2,
and shall cause to be provided to all Holders in accordance with Section 1.6,
notice of any tender offer by the Company or any Subsidiary for all or any
portion of the Common Stock at or about the time that such notice of tender
offer is provided to the public generally.

SECTION 12.7. COMPANY TO RESERVE COMMON STOCK.

         The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all Outstanding Securities.


                                     -97-


<PAGE>

SECTION 12.8. TAXES ON CONVERSIONS.

         Except as provided in the next sentence, the Company will pay any and
all taxes and duties that may be payable in respect of the issue or delivery of
shares of Common Stock on conversion of Securities pursuant hereto.  The Company
shall not, however, be required to pay any tax or duty which may be payable in
respect of any transfer involved in the issue and delivery of shares of Common
Stock in a name other than that of the Holder of the Security or Securities to
be converted, and no such issue or delivery shall be made unless and until the
Person requesting such issue has paid to the Company the amount of any such tax
or duty, or has established to the satisfaction of the Company that such tax or
duty has been paid.

SECTION 12.9. COVENANT AS TO COMMON STOCK.

         The Company agrees that all shares of Common Stock which may be
delivered upon conversion of Securities, upon such delivery, will have been duly
authorized and validly issued and will be fully paid and nonassessable and,
except as provided in Section 12.8, the Company will pay all taxes, liens and
charges with respect to the issue thereof.

SECTION 12.10. CANCELLATION OF CONVERTED SECURITIES.

         All Securities delivered for conversion shall be delivered to the
Trustee or its agent to be canceled by or at the direction of the Trustee, which
shall dispose of the same as provided in Section 3.9.

SECTION 12.11. PROVISION IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

         In case of any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security then Outstanding shall have the right thereafter, during the
period such Security shall be convertible as specified in Section 12.1, to
convert such Security only into the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, conveyance, sale,
transfer or lease by a holder of the number of shares of Common Stock of the
Company into which such Security might have been converted immediately prior to
such consolidation, merger, conveyance, sale, transfer or lease, assuming such
holder of Common Stock of the Company (i) is not a Person with which the Company
consolidated or merged with or into or which merged into or with the Company or
to which such conveyance, sale, transfer or lease was made, as the case may be
("Constituent Person"), or an Affiliate of a Constituent Person and (ii) failed
to exercise his rights of election, if any, as to the kind or amount of
securities, 


                                     -98-


<PAGE>

cash and other property receivable upon such consolidation, merger, 
conveyance, sale, transfer or lease (PROVIDED that if the kind or amount of 
securities, cash and other property receivable upon such consolidation, 
merger, conveyance, sale, transfer, or lease is not the same for each share 
of Common Stock of the Company held immediately prior to such consolidation, 
merger, conveyance, sale, transfer or lease by others than a Constituent 
Person or an Affiliate thereof and in respect of which such rights of 
election shall not have been exercised ("Non-electing Share"), then for the 
purpose of this Section 12.11 the kind and amount of securities, cash and 
other property receivable upon such consolidation, merger, conveyance, sale, 
transfer or lease by the holders of each Non-electing Share shall be deemed 
to be the kind and amount so receivable per share by a plurality of the 
Non-electing Shares), and further assuming, if such consolidation, merger, 
conveyance, transfer, sale or lease occurs prior to the 90th day following 
the last original issue date of the Securities, that the Security was 
convertible at the time of such occurrence at the Conversion Rate specified 
in Section 12.1 as adjusted from the issue date of such Security to such time 
as provided in this Article Twelve.  Such supplemental indenture shall 
provide for adjustments which, for events subsequent to the effective date of 
such supplemental indenture, shall be as nearly equivalent as may be 
practicable to the adjustments provided for in this Article.  The above 
provisions of this Section 12.11 shall similarly apply to successive 
consolidations, mergers, conveyances, sales, transfers or leases. Notice of 
the execution of such a supplemental indenture shall be given by the Company 
to the Holder of each Security as provided in Section 1.6 promptly upon such 
execution.

         Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or other securities or property or cash receivable by Holders of
Securities upon the conversion of their Securities after any such consolidation,
merger, conveyance, transfer, sale or lease or to any such adjustment, but may
accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, an Opinion of Counsel with respect thereto,
which the Company shall cause to be furnished to the Trustee upon request.

SECTION 12.12. RESPONSIBILITY OF TRUSTEE FOR CONVERSION PROVISIONS.

         The Trustee, subject to the provisions of Section 6.1, and any
Conversion Agent shall not at any time be under any duty or responsibility to
any Holder of Securities to determine whether any facts exist which may require
any adjustment of the Conversion Rate, or with respect to the nature or extent
of any such adjustment when made, or with respect to the method employed, or
herein or in any supplemental indenture provided to be employed, in making the
same, or whether a supplemental indenture need be entered into.  Neither the
Trustee, subject to the provisions of Section 6.1, nor any Conversion Agent
shall be accountable with respect to the validity or value (or the kind or
amount) of any Common Stock, or of any other securities or property or cash,
which may at any time be issued or delivered upon the conversion of any
Security; and it or they do not make any representation with respect thereto. 
Neither the Trustee, subject to the provisions of Section 6.1, nor any
Conversion Agent shall be responsible 


                                     -99-


<PAGE>

for any failure of the Company to make or calculate any cash payment or to 
issue, transfer or deliver any shares of Common Stock or share certificates 
or other securities or property or cash upon the surrender of any Security 
for the purpose of conversion; and the Trustee, subject to the provisions of 
Section 6.1, and any Conversion Agent shall not be responsible for any 
failure of the Company to comply with any of the covenants of the Company 
contained in this Article.

                               ARTICLE THIRTEEN

                         SUBORDINATION OF SECURITIES


SECTION 13.1. SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS.

         The Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article (subject to the provisions
of Article Four), the indebtedness represented by the Securities and the payment
of the principal of (and premium, if any) and interest on, and any payment of
the Repurchase Price with respect to, each and all of the Securities are hereby
expressly made subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness.

SECTION 13.2. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

         In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or (b) any liquidation, dissolution or other winding
up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling of assets and liabilities of the Company, then and in any
such event the holders of Senior Indebtedness shall be entitled to receive
payment in full of all amounts due or to become due on or in respect of all
Senior Indebtedness in cash before the Holders of the Securities are entitled to
receive any payment on account of principal of (or premium, if any) or interest
(including any Liquidated Damages) on the Securities or on account of the
purchase, redemption or other acquisition of Securities, and to that end the
holders of Senior Indebtedness shall be entitled to receive, for application to
the payment thereof, any payment or distribution of any kind or character,
whether in cash, property or securities, which may be payable or deliverable in
respect of the Securities in any such case, proceeding, dissolution, liquidation
or other winding up or event.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, securities or other property, before all Senior Indebtedness is
paid in full, and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event such payment or distribution shall be paid over
or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior


                                    -101-


<PAGE>

Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

         For purposes of this Article only, the words "cash, securities or
other property" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, which shares of stock
or securities are subordinated in right of payment to all then outstanding
Senior Indebtedness to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article.  The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article Seven shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of the Company
for the purposes of this Section if the Person formed by such consolidation or
into which the Company is merged or which acquires by conveyance or transfer
such properties and assets substantially as an entirety, as the case may be,
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions set forth in Article Seven.

SECTION 13.3. NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

         (a)  In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on (including a default
under any redemption or repurchase obligation with respect to) any Senior
Indebtedness beyond any applicable grace period with respect thereto or in the
event that any other event of default with respect to any Senior Indebtedness
shall have occurred and be continuing which would then permit the holders of
such Senior Indebtedness to declare such Senior Indebtedness due and payable
prior to the date on which it would otherwise have become due and payable,
unless and until such event of default shall have been cured or waived or shall
have ceased to exist after written notice to the Company and the Trustee by any
holder of such Senior Indebtedness, or any trustee, agent or representative
therefor or (b) in the event any judicial proceeding shall be pending with
respect to any such default in payment or event of default, then no payment
shall be made by the Company on account of principal of (or premium, if any) or
interest (including Liquidated Damages) on the Securities or on account of the
purchase, redemption or other acquisition of Securities.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company, in the case of the Trustee, or the Trustee,
in the case of such Holder.


                                    -102-


<PAGE>

         The provisions of this Section shall not apply to any payment with 
respect to which Section 13.2 would be applicable.

SECTION 13.4. PAYMENT PERMITTED IF NO DEFAULT.

         Nothing contained in this Article or elsewhere in this Indenture or 
in any of the Securities shall prevent (a) the Company, at any time except 
during the pendency of any case, proceeding, dissolution, liquidation or 
other winding up, assignment for the benefit of creditors or other 
marshalling of assets and liabilities of the Company referred to in Section 
13.2 or under the conditions described in Section 13.3, from making payments 
at any time of principal of (and premium, if any) or interest on the 
Securities, or (b) the application by the Trustee of any money deposited with 
it hereunder to the payment of or on account of the principal of (and 
premium, if any) or interest on the Securities or the retention of such 
payment by the Holders, if, at the time of such application by the Trustee, 
it did not have knowledge that such payment would have been prohibited by the 
provisions of this Article.

SECTION 13.5. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

         Subject to the payment in full of all Senior Indebtedness, the 
Holders of the Securities shall be subrogated to the extent of the payments 
or distributions made to the holders of such Senior Indebtedness pursuant to 
the provisions of this Article to the rights of the holders of such Senior 
Indebtedness to receive payments and distributions of cash, property and 
securities applicable to the Senior Indebtedness until the principal of (and 
premium, if any) and interest on the Securities shall be paid in full.  For 
purposes of such subrogation, no payments or distributions to the holders of 
the Senior Indebtedness of any cash, property or securities to which the 
Holders of the Securities or the Trustee would be entitled except for the 
provisions of this Article, and no payments over pursuant to the provisions 
of this Article to the holders of Senior Indebtedness by Holders of the 
Securities or the Trustee, shall, as among the Company, its creditors other 
than holders of Senior Indebtedness and the Holders of the Securities, be 
deemed to be a payment or distribution by the Company to or on account of the 
Senior Indebtedness.

SECTION 13.6. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand.  Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders of
the Securities the principal of (and premium, if any) and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other 


                                       -103-


<PAGE>

than the holders of Senior Indebtedness; or (c) prevent the Trustee or the 
Holder of any Security from exercising all remedies otherwise permitted by 
applicable law upon default under this Indenture, subject to the rights, if 
any, under this Article of the holders of Senior Indebtedness to receive 
cash, property and securities otherwise payable or deliverable to the Trustee 
or such Holder.

SECTION 13.7. TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each holder of a Security by his acceptance thereof authorizes and 
directs the Trustee on his behalf to take such action as may be necessary or 
appropriate to effectuate the subordination provided in this Article and 
appoints the Trustee his attorney-in-fact for any and all such purposes.

SECTION 13.8. NO WAIVER OF SUBORDINATION PROVISIONS.

         No right of any present or future holder of any Senior Indebtedness 
to enforce subordination as herein provided shall at any time in any way be 
prejudiced or impaired by any act or failure to act on the part of the 
Company or by any act or failure to act, in good faith, by any such holder of 
any Senior Indebtedness, or by any non-compliance by the Company with the 
terms, provisions and covenants of this Indenture, regardless of any 
knowledge thereof any such holder may have or be otherwise charged with.

         Without in any way limiting the generality of the foregoing 
paragraph, the holders of Senior Indebtedness may, at any time and from time 
to time, without the consent of or notice to the Trustee or the Holders of 
the Securities, without incurring responsibility to the Holders of the 
Securities and without impairing or releasing the subordination provided in 
this Article or the obligations hereunder of the Holders of the Securities to 
the holders of Senior Indebtedness, do any one or more of the following:  (i) 
change the manner, place or terms of payment or extend the time of payment 
of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement 
in any manner Senior Indebtedness or any instrument evidencing the same or 
any agreement under which Senior Indebtedness is outstanding; (ii) sell, 
exchange, release or otherwise deal with any property pledged, mortgaged or 
otherwise securing Senior Indebtedness; (iii) release any Person liable in 
any manner for the collection of Senior Indebtedness; and (iv) exercise or 
refrain from exercising any rights against the Company and any other Person.

SECTION 13.9. NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, 


                                       -104-

unless and until the Trustee shall have received written notice thereof from 
the Company or a holder of Senior Indebtedness or from any trustee, agent or 
representative therefor; and, prior to the receipt of any such written 
notice, the Trustee, subject to the provisions of Section 6.1, shall be 
entitled in all respects to assume that no such facts exist; PROVIDED, 
HOWEVER, that if the Trustee shall not have received the notice provided for 
in this Section 13.9 prior to the date upon which by the terms hereof any 
money may become payable for any purpose (including, without limitation, the 
payment of the principal of (and premium, if any) or interest on any 
Security), then, anything herein contained to the contrary notwithstanding, 
the Trustee shall have full power and authority to receive such money and to 
apply the same to the purpose for which such money was received and shall not 
be affected by any notice to the contrary which may be received by it within 
two Business Days prior to such date.

         Subject to the provisions of Section 6.1, the Trustee shall be 
entitled to rely on the delivery to it of a written notice by a Person 
representing himself to be a holder of Senior Indebtedness (or a trustee, 
agent or representative therefor) to establish that such notice has been 
given by a holder of Senior Indebtedness (or a trustee, agent or 
representative therefor). In the event that the Trustee determines in good 
faith that further evidence is required with respect to the right of any 
Person as a holder of Senior Indebtedness to participate in any payment or 
distribution pursuant to this Article, the Trustee may request such Person to 
furnish evidence to the reasonable satisfaction of the Trustee as to the 
amount of Senior Indebtedness held by such Person, the extent to which such 
Person is entitled to participate in such payment or distribution and any 
other facts pertinent to the rights of such Person under this Article, and if 
such evidence is not furnished, the Trustee may defer any payment to such 
Person pending judicial determination as to the right of such Person to 
receive such payment.

SECTION 13.10.   RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING 
                 AGENT.

         Upon any payment or distribution of assets of the Company referred 
to in this Article, the Trustee, subject to the provisions of Section 6.1, 
and the Holders of the Securities shall be entitled to rely upon any order or 
decree entered by any court of competent jurisdiction in which such 
insolvency, bankruptcy, receivership, liquidation, reorganization, 
dissolution, winding up or similar case or proceeding is pending, or a 
certificate of the trustee in bankruptcy, receiver, liquidating trustee, 
custodian, assignee for the benefit of creditors, agent or other Person 
making such payment or distribution, delivered to the Trustee or to the 
Holders of Securities, for the purpose of ascertaining the Persons entitled 
to participate in such payment or distribution, the holders of the Senior 
Indebtedness and other indebtedness of the Company, the amount thereof or 
payable thereon, the amount or amounts paid or distributed thereon and all 
other facts pertinent thereto or to this Article.

SECTION 13.11.     TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.

         The Trustee shall not be deemed to owe any fiduciary duty to the 
holders of Senior Indebtedness and shall not be liable to any such holders if 
it shall in good faith mistakenly pay over or distribute to Holders of 
Securities or to the Company or to any other Person cash, property or 
securities to which any holders of Senior Indebtedness shall be entitled by 
virtue of this Article or otherwise.

SECTION 13.12.     RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS ON SUBORDINATION
                   PROVISIONS.

         Each Holder by accepting a Security acknowledges and agrees that the 
foregoing subordination provisions are, and are intended to be, an inducement 
and a consideration to each holder of any Senior Indebtedness, whether such 
Senior Indebtedness was created or acquired before or after the issuance of 
the Securities, to acquire and continue to hold, or to continue to hold, such 
Senior Indebtedness and such holder of Senior Indebtedness shall be deemed 
conclusively to have relied on such subordination provisions in acquiring and 
continuing to hold, or in continuing to hold, such Senior Indebtedness.

SECTION 13.13.     RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; 
                   PRESERVATION OF TRUSTEE'S RIGHTS.

         The Trustee in its individual capacity shall be entitled to all the 
rights set forth in this Article with respect to any Senior Indebtedness 
which may at any time be held by it, to the same extent as any other holder 
of Senior Indebtedness, and nothing in this Indenture shall deprive the 
Trustee of any of its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, 
the Trustee under or pursuant to Section 6.7.

SECTION 13.14.     ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall 
have been appointed by the Company and be then acting hereunder, the term 
"Trustee" as used in this Article shall in such case (unless the context 
otherwise requires) be construed as extending to and including such Paying 
Agent within its meaning as fully for all intents and purposes as if such 
Paying Agent were named in this Article in addition to or in place of the 
Trustee; PROVIDED, HOWEVER, that Section 13.13 shall not apply to the Company 
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

SECTION 13.15.     CERTAIN CONVERSIONS AND REPURCHASES DEEMED PAYMENT.

         For the purposes of this Article only, (1) the issuance and delivery 
of junior securities upon conversion of Securities in accordance with Article 
Twelve or upon the 


                                       -106-


<PAGE>

repurchase of Securities in accordance with Article Fourteen shall not be 
deemed to constitute a payment or distribution on account of the principal of 
or premium or interest on Securities or on account of the purchase or other 
acquisition of Securities, and (2) the payment, issuance or delivery of cash, 
property or securities (other than junior securities) upon conversion of a 
Security shall be deemed to constitute payment on account of the principal of 
such Security.  For the purposes of this Section, the term "junior 
securities" means (a) shares of any stock of any class of the Company and any 
cash, property or securities into which the Securities are convertible 
pursuant to Article Twelve and (b) securities of the Company which are 
subordinated in right of payment to all Senior Indebtedness which may be 
outstanding at the time of issuance or delivery of such securities to 
substantially the same extent as, or to a greater extent than, the Securities 
are so subordinated as provided in this Article.  Nothing contained in this 
Article or elsewhere in this Indenture or in the Securities is intended to or 
shall impair, as among the Company, its creditors other than holders of 
Senior Indebtedness and the Holders of the Securities, the right, which is 
absolute and unconditional, of the Holder of any Security to convert such 
Security in accordance with Article Twelve or to exchange such Security for 
Common Stock in accordance with Article Fourteen if the Company elects to 
satisfy the obligations under Article Fourteen by the delivery of Common 
Stock.

                    REPURCHASE OF SECURITIES AT THE OPTION OF THE
                           HOLDER UPON A CHANGE IN CONTROL


SECTION 14.1. RIGHT TO REQUIRE REPURCHASE.

         In the event that a Change in Control (as hereinafter defined) shall 
occur, then each Holder shall have the right, at the Holder's option, but 
subject to the provisions of Section 14.2, to require the Company to 
repurchase, and upon the exercise of such right the Company shall repurchase, 
all of such Holder's Securities not theretofore called for redemption, or any 
portion of the principal amount thereof that is equal to U.S.$5,000 or any 
integral multiple of U.S.$1,000 in excess thereof (PROVIDED that no single 
Security may be repurchased in part unless the portion of the principal 
amount of such Security to be Outstanding after such repurchase is equal to 
U.S.$5,000 or integral multiples of U.S.$1,000 in excess thereof), on the 
date (the "Repurchase Date") that is 45 days after the date of the Company 
Notice (as defined in Section 14.3) at a purchase price equal to 100% of the 
principal amount of the Securities to be repurchased plus interest accrued to 
the Repurchase Date (the "Repurchase Price"); PROVIDED, HOWEVER, that 
installments of interest on Securities whose Stated Maturity is on or prior 
to the Repurchase Date shall be payable to the Holders of such Securities, or 
one or more Predecessor Securities, registered as such on the relevant Record 
Date according to their terms and the provisions of Section 3.7.  Such right 
to require the repurchase of the Securities shall not continue after a 
discharge of the Company from its obligations with respect to the Securities 
in accordance with Article Four, unless a Change in Control shall have 
occurred prior to such discharge.  At the option of the Company, the 
Repurchase Price may be paid in cash or, subject to the fulfillment by the 
Company of the conditions set forth Section 14.2, by delivery of shares of 
Common Stock having a fair market value equal to the Repurchase Price.  
Whenever in this Indenture (including Sections 2.2, 3.1, 5.1(1) and 5.8) 
there is a reference, in any context, to the principal of any Security as of 
any time, such reference shall be deemed to include reference to the 
Repurchase Price payable in respect of such Security to the extent that such 
Repurchase Price is, was or would be so payable at such time, and express 
mention of the Repurchase Price in any provision of this Indenture shall not 
be construed as excluding the Repurchase Price in those provisions of this 
Indenture when such express mention is not made; PROVIDED, HOWEVER, that for 
the purposes of Article Thirteen such reference shall be deemed to include 
reference to the Repurchase Price only to the extent the Repurchase Price is 
payable in cash.

SECTION 14.2. CONDITIONS TO THE COMPANY'S ELECTION TO PAY THE
              REPURCHASE PRICE IN COMMON STOCK.               

    The Company may elect to pay the Repurchase Price by delivery of shares 
of Common Stock pursuant to Section 14.1 if and only if the following 
conditions shall have been satisfied:


                                       -108-


<PAGE>

         (a)  The shares of Common Stock deliverable in payment of the 
Repurchase Price shall have a fair market value as of the Repurchase Date of 
not less than the Repurchase Price.  For purposes of Section 14.1 and this 
Section 14.2, the fair market value of shares of Common Stock shall be 
determined by the Company and shall be equal to 95% of the average of the 
Closing Prices Per Share for the five consecutive Trading Days immediately 
preceding the second Trading Day prior to the Repurchase Date;

         (b)  The Repurchase Price shall be paid only in cash in the event 
any shares of Common Stock to be issued upon repurchase of Securities 
hereunder (i) require registration under any federal securities law before 
such shares may be freely transferrable without being subject to any transfer 
restrictions under the Securities Act upon repurchase and if such 
registration is not completed or does not become effective prior to the 
Repurchase Date, and/or (ii) require registration with or approval of any 
governmental authority under any state law or any other federal law before 
such shares may be validly issued or delivered upon repurchase and if such 
registration is not completed or does not become effective or such approval 
is not obtained prior to the Repurchase Date;

         (c)  Payment of the Repurchase Price may not be made in Common Stock 
unless such stock is, or shall have been, approved for quotation on the 
Nasdaq National Market or listed on a national securities exchange, in either 
case, prior to the Repurchase Date; and
 
         (d)  All shares of Common Stock which may be issued upon repurchase 
of Securities will be issued out of the Company's authorized but unissued 
Common Stock and, will upon issue, be duly and validly issued and fully paid 
and non-assessable and free of any preemptive rights.

         If all of the conditions set forth in this Section 14.2 are not 
satisfied in accordance with the terms thereof, the Repurchase Price shall be 
paid by the Company only in cash.

SECTION 14.3.      NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC.

         (a)  Unless the Company shall have theretofore called for redemption 
all of the Outstanding Securities, on or before the 30th day after the 
occurrence of a Change in Control, the Company or, at the request and expense 
of the Company on or before the 15th day after such occurrence, the Trustee, 
shall give to all Holders of Securities, in the manner provided in Section 
1.6, notice (the "Company Notice") of the occurrence of the Change of Control 
and of the repurchase right set forth herein arising as a result thereof.  
The Company shall also deliver a copy of such notice of a repurchase right to 
the Trustee.

         Each notice of a repurchase right shall state:

         (1)  the Repurchase Date,


                                       -109-


<PAGE>

         (2)  the date by which the repurchase right must be exercised,

         (3)  the Repurchase Price, and whether the Repurchase Price shall be
    paid by the Company in cash or by delivery of shares of Common Stock,

         (4)  a description of the procedure which a Holder must follow to
    exercise a repurchase right, and the place or places where such Securities,
    are to be surrendered for payment of the Repurchase Price and accrued
    interest, if any,

         (5)  that on the Repurchase Date the Repurchase Price, and accrued
    interest, if any, will become due and payable upon each such Security
    designated by the Holder to be repurchased, and that interest thereon shall
    cease to accrue on and after said date,

         (6)  the Conversion Rate then in effect, the date on which the right
    to convert the principal amount of the Securities to be repurchased will
    terminate and the place or places where such Securities may be surrendered
    for conversion, and

         (7)  the place or places that the certificate required by Section 2.2
    shall be delivered, and the form of such certificate and the place or
    places that the Surrender Certificate required by Section 14.3(i) shall be
    delivered.

         No failure of the Company to give the foregoing notices or defect 
therein shall limit any Holder's right to exercise a repurchase right or 
affect the validity of the proceedings for the repurchase of Securities.

         If any of the foregoing provisions or other provisions of this 
Article Fourteen are inconsistent with applicable law, such law shall govern.

         (b)  To exercise a repurchase right, a Holder shall deliver to the 
Trustee on or before the 30th day after the date of the Company Notice (i) 
written notice of the Holder's exercise of such right, which notice shall set 
forth the name of the Holder, the principal amount of the Securities to be 
repurchased (and, if any Security is to repurchased in part, the serial 
number thereof, the portion of the principal amount thereof to be repurchased 
and the name of the Person in which the portion thereof to remain Outstanding 
after such repurchase is to be registered) and a statement that an election 
to exercise the repurchase right is being made thereby, and, in the event 
that the Repurchase Price shall be paid in shares of Common Stock, the name 
or names (with addresses) in which the certificate or certificates for shares 
of Common Stock shall be issued, and (ii) the Securities with respect to 
which the repurchase right is being exercised.  Such written notice shall be 
irrevocable, except that the right of the Holder to convert the Securities 
with respect to which the repurchase right is being exercised shall continue 
until the close of business on the Repurchase Date.


                                       -110-


<PAGE>

         (c)  In the event a repurchase right shall be exercised in 
accordance with the terms hereof, the Company shall pay or cause to be paid 
to the Trustee the Repurchase Price in cash or shares of Common Stock, as 
provided above, for payment to the Holder on the Repurchase Date or, if 
shares of Common Stock are to be paid, as promptly after the Repurchase Date 
as practicable, together with accrued and unpaid interest to the Repurchase 
Date payable with respect to the Securities as to which the purchase right 
has been exercised; PROVIDED, HOWEVER, that installments of interest that 
mature on or prior to the Repurchase Date shall be payable in cash to the 
Holders of such Securities, or one or more Predecessor Securities, registered 
as such at the close of business on the relevant Regular Record Date.  

         (d)  If any Security (or portion thereof) surrendered for repurchase 
shall not be so paid on the Repurchase Date, the principal amount of such 
Security (or portion thereof, as the case may be) shall, until paid, bear 
interest to the extent permitted by applicable law from the Repurchase Date 
at the rate of 5 1/2% per annum, and each Security shall remain convertible 
into Common Stock until the principal of such Security (or portion thereof, 
as the case may be) shall have been paid or duly provided for.

         (e)  Any Security which is to be repurchased only in part shall be 
surrendered to the Trustee (with, if the Company or the Trustee so requires, 
due endorsement by, or a written instrument of transfer in form satisfactory 
to the Company and the Trustee duly executed by, the Holder thereof or his 
attorney duly authorized in writing), and the Company shall execute, and the 
Trustee shall authenticate and make available for delivery to the Holder of 
such Security without service charge, a new Security or Securities, 
containing identical terms and conditions, each in an authorized denomination 
in aggregate principal amount equal to and in exchange for the unrepurchased 
portion of the principal of the Security so surrendered.  

         (f)  Any issuance of shares of Common Stock in respect of the 
Repurchase Price shall be deemed to have been effected immediately prior to 
the close of business on the Repurchase Date and the Person or Persons in 
whose name or names any certificate or certificates for shares of Common 
Stock shall be issuable upon such repurchase shall be deemed to have become 
on the Repurchase Date the holder or holders of record of the shares 
represented thereby; PROVIDED, HOWEVER, that any surrender for repurchase on 
a date when the stock transfer books of the Company shall be closed shall 
constitute the Person or Persons in whose name or names the certificate or 
certificates for such shares are to be issued as the record holder or holders 
thereof for all purposes at the opening of business on the next succeeding 
day on which such stock transfer books are open.  No payment or adjustment 
shall be made for dividends or distributions on any Common Stock issued upon 
repurchase of any Security declared prior to the Repurchase Date.

         (g)  No fractions of shares shall be issued upon repurchase of
Securities.  If more than one Security shall be repurchased from the same Holder
and the Repurchase Price shall be payable in shares of Common Stock, the number
of full shares which shall be issuable upon such repurchase shall be computed on
the basis of the aggregate principal amount of the Securities 


                                       -111-


<PAGE>

so repurchased. Instead of any fractional share of Common Stock which would 
otherwise be issuable on the repurchase of any Security or Securities, the 
Company will deliver to the applicable Holder its check for the current 
market value of such fractional share.  The current market value of a 
fraction of a share is determined by multiplying the current market price of 
a full share by the fraction, and rounding the result to the nearest cent.  
For purposes of this Section, the current market price of a share of Common 
Stock is the Closing Price Per Share of the Common Stock on the Trading Day 
immediately preceding the Repurchase Date.

         (h)  Any issuance and delivery of certificates for shares of Common 
Stock on repurchase of Securities shall be made without charge to the Holder 
of Securities being repurchased for such certificates or for any tax or duty 
in respect of the issuance or delivery of such certificates or the securities 
represented thereby; PROVIDED, HOWEVER, that the Company shall not be 
required to pay any tax or duty which may be payable in respect of (i) income 
of the Holder or (ii) any transfer involved in the issuance or delivery of 
certificates for shares of Common Stock in a name other than that of the 
Holder of the Securities being repurchased, and no such issuance or delivery 
shall be made unless and until the Person requesting such issuance or 
delivery has paid to the Company the amount of any such tax or duty or has 
established, to the satisfaction of the Company, that such tax or duty has 
been paid.

         (i)  If shares of Common Stock to be delivered upon repurchase of a 
Security are to be registered in a name other than that of the beneficial 
owner of such Security, then such Holder must deliver to the Trustee a 
Surrender Certificate, dated the date of surrender of such Restricted 
Security and signed by such beneficial owner, as to compliance with the 
restrictions on transfer applicable to such Restricted Security.  Neither the 
Trustee nor any Registrar or Transfer Agent or other agents shall be required 
to register in a name other than that of the beneficial owner shares of 
Common Stock issued upon repurchase of any such Restricted Security not so 
accompanied by a properly completed Surrender Certificate.

         (j)  All Securities delivered for repurchase shall be delivered to 
the Trustee to be canceled at the direction of the Trustee, which shall 
dispose of the same as provided in Section 3.9.

SECTION 14.4. CERTAIN DEFINITIONS.

         For purposes of this Article Fourteen,

         (a)  the term "beneficial owner" shall be determined in accordance 
with Rule 13d-3, as in effect on the date of the original execution of this

               exercise 50% or more of the total voting power of all shares
               of capital stock of the Company entitled to vote generally
               in the elections of directors (any shares of voting stock of
               which such person or group is the beneficial owner that are
               not then outstanding being deemed outstanding for purposes
               of calculating such percentage), other than any such

               outstanding shares of Common Stock and (y) pursuant to which
               holders of Common Stock immediately prior to such transaction
               have the entitlement to exercise, directly or indirectly, 50% or

               jurisdiction of incorporation of the Company and results in a
               reclassification, conversion or exchange of outstanding shares of
               Common Stock into solely shares of common stock);

PROVIDED, HOWEVER, that a Change in Control shall not be deemed to have

         Reference is made to the Indenture, dated as of May 28, 1996 (the

         This certificate relates to U.S. $____________ principal amount of 
Securities, which are evidenced by the following certificate(s) (the

         CUSIP No(s). ___________________________

         CERTIFICATE No(s). _____________________

The person in whose name this certificate is executed below (the 
"Undersigned") hereby certifies that either (i) it is the sole beneficial 
owner of the Specified Securities or (ii) it is acting on behalf of all the 
beneficial owners of the Specified Securities and is duly authorized by them

collectively as the "Owner". If the Specified Securities are represented by a 
Global Security, they are held through the Depositary or an Agent Member in

         The Owner has requested that the Specified Securities be transferred 
to a person (the "Transferee") who will take delivery in the form of a 
Regulation S Security.  In connection with such transfer, the Owner hereby 
certifies that, unless such transfer is being effected pursuant to an 
effective registration statement under the Securities Act, it is being 
effected in accordance with Rule 904 or Rule 144 under the Securities Act and 
with all applicable securities laws of the states of the United States and 
other jurisdictions.  Accordingly, the Owner hereby further certifies as

         accordance with Rule 904:

              (A)  the Owner is not a distributor of the Securities, an
         affiliate of the Company or any such distributor or a person acting on
         behalf of any of the foregoing;

              (B)  the offer of the Specified Securities was not made to a
         person in the United States;

              (C)    either:  

                   (i)  at the time the buy order was originated, the
              Transferee was outside the United States or the Owner and any
              person acting on its behalf reasonably believed that the
              Transferee was outside the United States, or

                   (ii)  the transaction is being executed in, on or through
              the facilities of the Eurobond market, as regulated by the
              Association of International Bond Dealers, or another designated
              offshore securities market and neither the Owner nor any person
              acting on its behalf knows that the transaction has been
              prearranged with a buyer in the United States;

              (D)  no directed selling efforts have been made in the United
         States by or on behalf of the Owner or any affiliate thereof; 

              (E)  if the Owner is a dealer in securities or has received a
         selling concession, fee or other remuneration in respect of the
         Specified Securities, and the transfer is to occur during the
         Restricted Period, then the requirements of Rule 904(c)(1) have been
         satisfied; and

              (F)  the transaction is not part of a plan or scheme to evade the
         registration requirements of the Securities Act.

         (2)  RULE 144 TRANSFERS.  If the transfer is being effected pursuant
    to Rule 144:

              (A)  the transfer is occurring after a holding period of at least
         two years (computed in accordance with paragraph (d) of Rule 144) has
         elapsed since the date the Specified Securities were acquired from the
         Company or from an affiliate (as such term is defined in Rule 144) of
         the Company, whichever is later, and is being effected in accordance
         with the applicable amount, manner of sale and notice requirements of

     jurisdiction as any selling holder or underwriter reasonably shall 
     request, (B) keep such registrations or qualifications in effect and 
     comply with such laws so as to permit the continuance of offers, sales

     necessary (but not to exceed three years from the Effective Time) to 
     enable any such holder or underwriter to complete its distribution of 
     Registrable Securities pursuant to the Registration Statement and (C) 
     take any and all other actions as may be reasonably necessary or 
     advisable to enable the disposition in such jurisdictions of such 
     Registrable Securities; PROVIDED, HOWEVER, that the Company shall not be 
     required for any such purpose to


                                      -9-

     jurisdiction;

          (x)  cooperate with the selling holders of Registrable Securities 
     and the managing underwriter or underwriters, if any, to facilitate the 
     timely preparation and delivery of certificates representing Registrable 
     Securities to be sold, which certificates shall not bear any restrictive 
     legends and which, if so required by any securities exchange upon which 
     any Registrable Securities are listed, shall be penned, lithographed or 
     engraved, or produced by any combination of such methods, on steel 
     engraved borders; and enable such Registrable Securities to be in such

     any, to consummate the disposition of such Registrable Securities;

          (xii)  if any fact contemplated by subparagraph (iv)(F) above shall 
     exist, prepare a post-effective amendment or supplement to the 
     Registration Statement or the related Prospectus or any document 
     incorporated therein by reference or file any other required document so 
     that the Prospectus, as thereafter delivered to the purchasers of the

          amendment to the Registration Statement, and at the time of the 
          signing of the underwriting or purchase agreement and at the time 
          of delivery of any Registrable Securities sold pursuant thereto, in 
          each case if so specified in such underwriting agreement, letters

          (A) above and compliance with any customary conditions contained in

     an offering, (B) commencing with the first month of the Company's first 
     fiscal quarter commencing after 


                                     -12-

     the effective date of the Registration Statement, which statements shall 
     cover said 12-month periods;

          (xvi)  notify in writing each holder of Registrable Securities of 
     any proposal by the Company to amend or waive any provision of this 
     Agreement pursuant to Section 9(h) hereof and of any amendment or waiver 
     effected pursuant thereto, each of which notices shall contain the text 
     of the amendment or waiver proposed or effected, as the case may be; and

          (xvii)  in the event that any broker-dealer registered under the 
     Exchange Act shall be an "Affiliate" (as defined in Schedule E to the 
     By-Laws of the National Association of Securities Dealers, Inc. 
     ("NASD")) of the Company or has a "Conflict of Interest" (as defined in 
     such Schedule) and such broker-dealer shall underwrite, participate as a 
     member of an underwriting syndicate or selling group or "assist in the 
     distribution" (within the meaning of such Schedule) of any Registrable 
     Securities, whether as a holder of such Registrable Securities or as an 
     underwriter, a placement or sales agent or a broker or dealer in respect 
     thereof, or otherwise, assist such broker-dealer in complying with the 
     requirements of such Schedule, including, without limitation, by (A) 
     engaging a "qualified independent underwriter" (as defined in such 
     Schedule) to participate in the preparation of the registration 
     statement relating to such Registrable Securities, to exercise usual 
     standards of due diligence in respect thereto and to recommend the 
     public offering price of such Registrable Securities, (B) indemnifying 
     such qualified independent underwriter to the extent of the 
     indemnification of underwriters provided in Section 6 hereof, and (C) 
     providing such information within the possession of the Company to such 
     broker-dealer as may be reasonably required in order for such 
     broker-dealer to comply with the requirements of the Rules of Fair 
     Practice of the NASD.

     (d)  Each seller of Registrable Securities as to which any 
registration is being effected shall use reasonable efforts to cooperate with 
the Company.  The Company may require each selling holder of Registrable 
Securities as to which any registration is being effected to furnish to the 
Company such information regarding such holder, the Registrable Securities 
held by such holder, the distribution of such Registrable Securities as the 
Company may from time to time reasonably request.  If a holder refuses to 
supply the Company with any of such information 


                                     -13-


<PAGE>


on the grounds that it is not necessary to include such information in the 
Registration Statement or for any other reason, the Company may exclude such 
holder's Registrable Securities from the Registration Statement if the 
Company provides such holder with a written opinion of counsel satisfactory 
to such holder to the effect that such information must be included in the 
Registration Statement and such holder thereafter continues to withhold such 
information.  The deletion of such holder's Registrable Securities from a 
registration shall not affect the registration of the other Registrable 
Securities to be included in the Registration Statement.  Each seller of 
Registrable Securities will furnish to the Company information concerning 
sales made pursuant to the Registration Statement.  Each such holder agrees, 
by the acquisition of Registrable Securities, and agrees to confirm such 
agreement in writing upon request of the Company, to notify  the Company as 
promptly as practicable of any inaccuracy or change in information previously 
furnished by such holder to the Company or of the occurrence of any event in 
either case as a result of which any Prospectus relating to such registration 
contains or would contain an untrue statement of a material fact regarding 
such holder or such holder's intended method of distribution of such 
Registrable Securities or omits to state any material fact regarding such 
holder or such holder's intended method of distribution of such  Registrable 
Securities necessary to make the statements therein, in light of the 
circumstances then existing, not misleading and promptly to furnish to the 
Company any additional information required to correct and update any 
previously furnished information or required so that such Prospectus shall 
not contain, with respect to such holder or the distribution of such 
Registrable Securities, an untrue statement of a material fact or omit to 
state a material fact necessary to make the statements therein, in light of 
the circumstances then existing, not misleading.

     (e)  Each holder of Registrable Securities agrees by acquisition of such 
Registrable Securities that, upon receipt of any notice from the Company of 
the happening of any event of the kind described in Section 3(c)(iv)(F) 
hereof, such holder will forthwith discontinue disposition of Registrable 
Securities pursuant to the Registration Statement until such holder's receipt 
of the copies of the supplemented or amended Prospectus contemplated by 
Section 3(c)(xii) hereof, or until it is advised in writing by the Company 
that the use of the Prospectus may be resumed, and has received copies of any 
additional or supplemental filings which are incorporated by reference in the 
Prospectus, and, if so directed by the Company, such holder will deliver to 
the Company (at the Company's expense) all


                                     -14-

copies, other than permanent file copies, then in such holder's possession 
of the Prospectus covering such Registrable Securities at the time of receipt 
of such notice.

qualification of the shares of Common Stock constituting Registrable

Registration Expenses are incurred, assumed or paid by any holder of 
Registrable Securities or any underwriter thereof, the Company shall 
reimburse such person for the full amount of the Registration Expenses so 
incurred, assumed or paid promptly after receipt of a request therefor. 
Notwithstanding the foregoing, the holders of the Registrable Securities 
being registered shall pay all agency fees and commissions and underwriting 
discounts and commissions attributable to the sale of such Registrable

material respects to the requirements of the Securities Act and will not 
contain an untrue statement of a material fact or omit to state a material

     6.   INDEMNIFICATION.

     (a)  INDEMNIFICATION BY THE COMPANY.  Upon the registration of the 
Registrable Securities pursuant to Section 2 hereof, and in consideration of 
the agreements of the Purchasers contained herein and in the Purchase 
Agreement, and as an inducement to the Purchasers to enter into such 
Agreements, the Company shall, and it hereby agrees to, indemnify and hold 
harmless each of the holders of Registrable Securities to be included in 
such registration, each underwriter, selling agent or placement agent with 
respect to the Registrable Securities and each of their respective officers, 
directors, employees and agents and each person who controls such holder or 
underwriter, selling agent or placement agent within the meaning of Section 
15 of the Securities Act or Section 20 of the Exchange Act (each such person 
being sometimes referred to as an "Indemnified Person") against any losses, 
claims, damages or liabilities, joint or several, to which such Indemnified 
Person may become subject under the Securities Act or otherwise, insofar as 
such losses, claims, damages or liabilities (or actions in respect thereof) 
arise out of or are based up on an untrue statement or alleged untrue 
statement of a material fact contained in any Registration Statement under 
which such Registrable Securities were registered under the Securities Act, 
or any Prospectus contained th erein or furnished by the Company to any 
Indemnified Person, or any amendment or supplement thereto, or arise out of 
or are based upon the omission or alleged omission to state therein a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading, and the Company shall, and it hereby 
agrees to, reimburse such Indemnified Person for any reasonable legal or 
other expenses reasonably incurred by them in connection with investigating 
or defending any such action 


                                     -18-


<PAGE>

or claim, it being understood that the Purchaser shall not, in connection 
with any one such action or separate but substantially similar related 
actions arising out of the same general allegations or circumstances, be 
liable for the fees and exp  enses of more than one separate firm or 
attorneys (other than local counsel) for all Indemnified Persons; PROVIDED, 
HOWEVER, that the Company shall not be liable to any such Indemnified Person 
in any such case to the extent that any such loss, claim, damage or liability 
arises out of or is based upon an untrue statement or alleged untrue 
statement or omission or alleged omission made in such Registration Statement 
or Prospectus, or amendment or supplement, in reliance upon and in conformity 
with written information furnished to the Company by or on behalf of such 
Indemnified Person expressly for use therein.

     (b)  INDEMNIFICATION BY THE HOLDERS AND ANY AGENTS AND UNDERWRITERS.  
The Company may require, as a condition to including any Registrable 
Securities in any Registration Statement filed pursuant to this Agreement and 
to entering into any underwriting agreement with respect thereto, that the 
Company shall have received an undertaking reasonably satisfactory to it from 
the holder of such Registrable Securities and from each underwriter named in 
any such underwriting agreement, severally and not jointly, to (i) indemnify 
and hold harmless the Company, its directors, officers who sign any 
Registration Statement and each person, if any, who controls the Company 
within the meaning of either Section 15 of the Securities Act or Section 20 
of the Exchange Act, against any losses, claims, damages or liabilities to 
which the Company or such other persons may become subject, under the 
Securities Act or otherwise, insofar as such losses, claims, damages or 
liabilities (or actions in respect thereof) arise out of or are based upon an 
untrue st atement or alleged untrue statement of a material fact contained in 
such Registration Statement, or any Prospectus contained therein or furnished 
by the Company to any such holder or underwriter, or any amendment or 
supplement thereto, or arise out of or are based upon the omission or alleged 
omission to state therein a material fact required to be stated therein or 
necessary to make the statements therein not misleading, in each case to the 
extent, but only to the extent, that such untrue statement or alleged untrue 
statement or omission or alleged omission was made in reliance upon and in 
conformity with written information furnished in writing to the Company by or 
on behalf of such holder or underwriter expressly for use therein, and (ii) 
reimburse the Company for any legal or other expens es reasonably incurred by 
the Company in connection with investigating or defending any such action or 
claim, it being understood that the Purchasers shall not, 


                                     -19-


<PAGE>


in connection with any one such action or separate but substantially similar 
related actions arising out of the same general allegations or circumstances, 
be liable for the fees and exp  enses of more than one separate firm or 
attorneys (other than local counsel) for the Company;

     (c)  NOTICES OF CLAIMS, ETC.  Promptly after receipt by an indemnified 
party under subsection (a) or (b) above of written notice of the commencement 
of any action, such indemnified party shall, if a claim in respect thereof is 
to be made against an indemnifying party pursuant to the indemnification 
provisions of or contemplated by this Section 6, notify such indemnifying 
party in writing of the commencement of such action; but the omission so to 
notify the indemnifying party shall not relieve it from any liability which 
it may have to any indemnified party other than under the indemnification 
provisions of or contemplated by Section 6(a) or 6(b) hereof.  In case any 
such action shall be brought against any indemnified party and it shall 
notify an indemnifying party of the commencement thereof, such indemnifying 
party shall be entitled to participate therein and, to the extent that it 
shall wish, jointly with any other indemnifying party similarly notified, to 
assume the defense thereof, with counsel reasonably satisfactory to such 
indemnified party (who shall not, except with the consent of the 
indemnified party, be counsel to the indemnifying party), and, after notice 
from the indemnifying party to such indemnified party of its election so to 
assume the defense thereof, such indemnifying party shall not be liable to 
such indemnified party for any legal expenses of other counsel or any 
other expenses, in each case subsequently incurred by such indemnified 
party, in connection with the defense thereof other than reasonable costs of 
investigation. No indemnifying party shall, without the written consent of 
the indemnified party, effect the settlement or compromise of, or consent to 
the entry of any judgment with respect to, any pending or threatened action 
or claim in respect of which indemnification or contribution may be sought 
hereunder (whether or not the indemnified party is an actual or potential 
party to such action or claim) unless such settlement, compromise or judgment 
(i) includes an unconditional release of the indemnified party from all 
liability arising out of such action or claim and (ii) does not include a 
statement as to, or an admission of, fault, culpability or a failure to act, 
by or on behalf of any indemnified party.
                                                     
     (d)  CONTRIBUTION.  Each party hereto agrees that, if for any reason the 
indemnification provisions contemplated by Section 6(a) or Section 6(b) are 
unavailable to or insufficient to hold harmless an indemnified party in 


                                     -20-


<PAGE>

respect of any losses, claims, damages or liabilities (or actions in respect 
thereof) referred to therein, then each indemnifying party shall contribute 
to the amount paid or payable by such indemnified party as a result of such 
losses, claims, damages or liabilities (or actions in respect thereof) in 
such proportion as is appropriate to reflect the relative fault of the 
indemnifying party and the indemnified party in connection with the 
statements or omissions which resulted in such losses, claims, damages or 
liabilities (or actions in respect thereof), as well as any other relevant 
equitable considerations.  The relative fault of such indemnifying party and 
indemnified party shall be determined by reference to, among other things, 
whether the untrue or alleged untrue statement of a material fact or omission 
or alleged omission to state a material fact relates to information supplied 
by such indemnifying party or by such indemnified party, and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such statement or omission.  The parties hereto agree that it 
would not be just and equitable if contribution pursuant to this Section 6(d) 
were determined by pro rata allocation (even if the holders or any agents or 
underwriters or all of them were treated as one entity for such purpose) or 
by any other method of allocation which does not take account of the 
equitable considerations referred to in this Section 6(d).  The amount paid 
or payable by an indemnified party as a result of the losses, claims, damages 
or liabilities (or actions in respect thereof) referred to above shall be 
deemed to include any legal or other fees or expenses reasonably incurred by 
such indemnified party in connection with investigating or defending any 
such action or claim.  No person guilty of fraudulent misrepresentation 
(within the meaning of Section 11(f) of the Securities Act) shall be entitled 
to contribution from any person who was not guilty of such fraudulent 
misrepresentation.  The holders' and any underwriters' obligations in this 
Section 6(d) to contribute shall be several in proportion to the percentage 
of principal amount of Registrable Securities registered or underwritten, as 
the case may be, by them and not joint.

     (e)  Notwithstanding any other provision of this Section 6, in no event 
will any (i) holder be required to undertake liability to any person under 
this Section 6 for any amounts in excess of the dollar amount of the proceeds 
to be received by such holder from the sale of such holder's Registrable 
Securities (after deducting any fees, discounts and commissi ons applicable 
thereto) pursuant to such registration and (ii) underwriter be required to 
undertake liability to any person hereunder for any amounts in excess of the 
discount, commission or other compensation payable to


                                     -21-

<PAGE>

such underwriter with respect to the Registrable Securities underwritten by 
it and distributed to the public pursuant to any such underwriting agreement.

     (f)  The obligations of an indemnifying party under this Section 6 shall 
be in addition to any liability which such indemnifying party may otherwise 
have to any Indemnified Person, including any liability of the Company to the 
Purchasers pursuant to Section 8 of the Purchase Agreement.

     In the event that any provision of an indemnification clause in an 
underwriting agreement executed by or on behalf of a holder of Registrable 
Securities differs from a provision in this Section 6, such provision in the 
underwriting agreement shall determine such holder's rights in respect thereof.

     7.   UNDERWRITTEN OFFERINGS.

     (a)  SELECTION OF UNDERWRITERS.  If any of the Registrable Securities 
covered by the Registration Statement are to be sold pursuant to an 
underwritten offering, the managing underwriter or underwriters thereof shall 
be designated by the holders of at least 50% in aggregate principal amount of 
the outstanding Registrable Securities to be included in such offering, 
provided that such designated managing underwriter or underwriters is or are 
reasonably acceptable to the Company.

     (b)  PARTICIPATION BY HOLDERS.  Each holder of Registrable Securities 
hereby agrees with each other such holder that no such holder may participate 
in any underwritten offering hereunder unless such holder (i) agrees to sell 
such holder's Registrable Securities on the basis provided in any 
underwriting arrangements approved by the persons entitled hereunder to 
approve such arrangements and (ii) completes and executes all questionnaires, 
powers of attorney, indemnities, underwriting agreements and other documents 
reasonably required under the terms of such underwriting arrangements.

     8.  RULE 144.

     The Company covenants to the holders of Registrable Securities that to 
the extent it shall be required to do so under the Exchange Act, the Company 
shall timely file the reports required to be filed by it under the Exchange 
Act or the Securities Act (including, but not 


                                     -22-


<PAGE>

limited to, the reports under Sections 13 and 15(d) of the Exchange Act 
referred to in subparagraph (c)(1) of Rule 144 under the Securities Act) and 
the Rules and Regulations, and shall take such further action as any holder 
of Registrable Securities may reasonably request, all to the extent required 
from time to time to enable such holder to sell Registrable Securities 
without registration under the Securities Act within the limitations of the 
exemption provided by Rule 144 under the Securities Act, as such Rule may be 
amended from time to time, or any similar rule or regulation hereafter 
adopted by the Commission.  Upon the request of any holder of Registrable 
Securities, the Company shall deliver to such holder a written statement as 
to whether it has complied with such requirements.

     9.  MISCELLANEOUS.

     (a)  NO INCONSISTENT AGREEMENTS.  The Company will not on or after 
the date of this Agreement grant registration rights with respect to 
Registrable Securities or any other securities, or enter into any agreement 
with respect to its securities, which is inconsistent with the rights granted 
to the holders of Registrable Securities in this Agreement or otherwise 
conflicts with the provisions hereof.  The Company is not currently a party 
to any agreement with respect to any of its equity or debt securities 
granting any registration rights to any person.

     (b)  SPECIFIC PERFORMANCE.  The parties hereto acknowledge that there 
may be no adequate remedy at law if any party fails to perform any of its 
obligations hereunder and that each party may be irreparably harmed by any 
such failure, and accordingly agree that each party, in addition to any other 
remedy to which it may be entitled at law or in equity, shall be entitled to 
compel specific performance of the obligations of any other party under this 
Agreement in accordance with the terms and conditions of this Agreement, in 
any court of the United States or any State thereof having jurisdiction.

     (c)  NOTICES.  All notices, requests, claims, demands, waivers and other 
communications hereunder shall be given in the manner provided for in the 
Indenture.

     (d)  PARTIES IN INTEREST.  All the terms and provisions of this 
Agreement shall be binding upon, shall inure to the benefit of and shall be 
enforceable by the respective successors and assigns of the parties hereto.  
In the event that any transferee of any holder of Registrable Securities 
shall acquire Registrable Securities, in any 


                                     -23-


<PAGE>

manner, whether by gift, bequest, purchase, operation of law or otherwise, 
such transferee shall, without any further writing or action of any kind, be 
deemed a party hereto for all purposes and such Registrable Securities shall 
be held subject to all of the terms of this Agreement, and by taking and 
holding such Registrable Securities such transferee shall be entitled to 
receive the benefits of and be conclusively deemed to have agreed to be bound 
by and to perform all of the terms and provisions of this Agreement. If the 
Company shall so request, any such successor, assign or transferee shall 
agree in writing to acquire and hold the Registrable Securities subject to 
all of the terms hereof.

     (e)  SURVIVAL.  The respective indemnities, agreements, representations, 
warranties and each other provision set forth in this Agreement or made 
pursuant hereto shall remain in full force and effect regardless of any 
investigation (or statement as to the results thereof) made by or on behalf 
of any holder of Registrable Securities, any director, officer or partner of 
such holder, any agent or underwriter or any director, officer or partner 
thereof, or any controlling person of any of the foregoing, and shall survive 
delivery of and payment for the Registrable Securities pursuant to the 
Purchase Agreement and the transfer and registration of Registrable 
Securities by such holder.

     (f)  LAW GOVERNING.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED 
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     (g)  HEADINGS.  The descriptive headings of the several Sections and 
paragraphs of this Agreement are inserted for convenience only, do not 
constitute a part of this Agreement and shall not affect in any way the 
meaning or interpretation of this Agreement.

     (h)  AMENDMENTS AND WAIVERS.  This Agreement may be amended and the 
observance of any term of this Agreement may be waived (either generally or 
in a particular instance and either retroactively or prospectively) only by a 
written instrument duly executed by the Company and the holders of at least a 
majority of the principal amount of the Registrable Securities at the time 
outstanding.  Each holder of any Registrable Securities at the time or 
thereafter outstanding shall be bound by any amendment or waiver effected 
pursuant to this Section 9(h), whether or not any notice, writing or marking 
indicating such amendment or waiver appears on such Registrable Securities 
or is delivered to such holder.


                                     -24-

     (i)  INSPECTION.  For so long as this Agreement shall be in effect, this 
Agreement and a complete list of the names and addresses of all the holders 
of Registrable Securities shall be made available for inspection and copying 
on any business day by any holder of Registrable Securities at the offices of 
the Company at the address set forth in the Indenture.

     (j)  COUNTERPARTS.  This Agreement may be executed in two or more 
counterparts, each of which shall be deemed an original, but all of which 
together shall constitute one and the same instrument.

                             August 22, 1996


Cyrix Corporation
2703 North Central Expressway
Richardson, Texas  75080

Ladies and Gentlemen:

    We have acted as counsel for Cyrix Corporation, a Delaware corporation 
(the "COMPANY"), in connection with the registration under the Securities Act 
of 1933 (the "SECURITIES ACT") on a Registration Statement on Form S-3 (the 
"REGISTRATION STATEMENT") of holders' resales of $126,500,000  aggregate 
principal amount of the Company's 5 1/2% Convertible Subordinated Notes due 
June 1, 2001 (the "NOTES") and such indeterminate number of shares of Common 
Stock, par value $0.004 per share, of the Company (the "COMMON STOCK") as 
shall be issuable upon conversion of the Notes in accordance with their terms.

    In reaching the opinions set forth in this letter, we have reviewed 
originals or copies of the Registration Statement, the Notes and such other 
agreements, certificates of public officials, certificates of officers of the 
Company, certificates of other persons, records, documents and matters of law 
as we deemed relevant.

    Based on and subject to the foregoing and subject further to the 
assumptions, exceptions and qualifications hereinafter stated, we are of the 
opinion that:

    1.   The Notes have been duly authorized, executed, issued and delivered 
by the Company and constitute valid and legally binding obligations of the 
Company entitled to the benefits provided by the Indenture, dated as of May 28,
1996 (the "Indenture"), between the Company and Bank of Montreal Trust 
Company, as trustee (the "Trustee");

    2.   The Indenture is a valid and legally binding instrument of the 
Company, enforceable against the Company in accordance with its terms, 
subject, as to enforcement, to bankruptcy, insolvency, fraudulent conveyance, 
reorganization and other laws of general applicability relating to or 
affecting creditors' rights and to general equity principles; and 

    3.   The shares of Common Stock issuable upon conversion of the Notes in 
accordance with their terms, when so issued, will be validly issued, fully 
paid and non-assessable.

    The opinions expressed above are subject to the following assumptions, 
exceptions and qualifications:

<PAGE>

    a.   We have assumed that (i) all information contained in all documents 
reviewed by us is true and correct, (ii) all signatures on all documents 
reviewed by us are genuine, (iii) all documents submitted to us as originals 
are true and complete, (iv) all documents submitted to us as copies are true 
and complete copies of the originals thereof, (v) each natural person signing 
any document reviewed by us had the legal capacity to do so, (vi) each 
natural person signing in a representative capacity any document reviewed by 
us had authority to sign in such capacity and, (vii) the Indenture is a valid 
and binding agreement of the Trustee.

    b.   The opinions expressed in this letter are limited to the Delaware 
General Corporation Law, the federal laws of the United States of America and 
the laws of the State of New York.  We express no opinion about the effect of 
the laws of any other jurisdiction.

    This opinion may be filed as an exhibit to the Registration Statement.  
Consent is also given to the reference to this firm under the caption "Legal 
Matters" in the Prospectus included in the Registration Statement as having 
passed on certain legal matters in connection with the Notes and the Common 
Stock.  In giving this consent we do not admit that we come within the 
category of persons whose consent is required under Section 7 of the 
Securities Act or the rules and regulations of the Securities and Exchange 
Commission promulgated thereunder.

    This opinion speaks as of the date hereof, and we disclaim any duty to 
advise you regarding any changes subsequent to the date hereof in, or to 
otherwise communicate with you with respect to, the matters addressed herein.

                                       Very truly yours,

                                       /s/ VINSON & ELKINS L.L.P.

                        CONSENT OF INDEPENDENT AUDITORS
 
    We consent to the reference to our firm under the caption "Experts" in the
Registration Statement (Form S-3) and related Prospectus of Cyrix Corporation
for the sale of $126,500,000 of 5 1/2% Convertible Subordinated Notes due June
1, 2001 and to the incorporation by reference therein of our report dated
January 18, 1996, with respect to the consolidated financial statements and
schedule of Cyrix Corporation included in its Annual Report (Form 10-K) for the
year ended December 31, 1995, filed with the Securities and Exchange Commission.
