                               PROSPECTUS SUMMARY

     This prospectus is part of a registration statement that we filed with the
SEC utilizing a "shelf" registration process. Under this shelf process, we may,
from time to time, sell in one or more offerings up to a total dollar amount of
$600,000,000 of any combination of the following securities:

     - shares of our common stock, and

     - our debt securities.

     This prospectus provides you with a general description of the securities
we may offer. Each time we sell securities, we will provide a prospectus
supplement that will contain specific information about the terms of that
offering, including the specific amounts, prices and terms of the securities
offered. The prospectus supplement may also add, update or change information
contained in this prospectus. You should read both this prospectus and any
prospectus supplement together with additional information described below under
the heading "Where You Can Find More Information."

     We encourage you to read our annual report on Form 10-K, and quarterly
reports on Form 10-Q, in each case, as amended. Instructions on how you can get
copies of these documents are provided below under the heading "Where You Can
Find More Information."

COMMON STOCK

     We may issue shares of common stock. Common stockholders are entitled to
receive dividends declared by the Board of Directors, subject to rights of
preferred stock holders. Currently, we do not pay a dividend. Each holder of
common stock is entitled to one vote per share. The holders of common stock have
no preemptive rights.

DEBT SECURITIES


     We may offer unsecured general obligations in the form of either senior or
subordinated debt. We refer to the senior debt securities and the subordinated
debt securities as the "debt securities" in this prospectus. The senior debt
securities will have the same rank as all of our other unsecured, unsubordinated
debt. The subordinated debt securities will be entitled to payment only after
payment on our senior indebtedness and will rank equally with our outstanding
4 1/4% convertible subordinated notes due 2004. Senior indebtedness generally
includes all indebtedness for money borrowed by us, except indebtedness that is
stated to be not senior to, or to have the same rank as, or is expressly junior
to the subordinated debt securities.


     The senior and subordinated debt will be issued under separate indentures
between us and State Street Bank and Trust Company of California, N.A., as
trustee. We have summarized the general features of the debt from the
indentures. We encourage you to read the indentures which are exhibits to this
Registration Statement No. (333-83963).

                             LSI LOGIC CORPORATION

     We are a worldwide leader in the design, development, manufacture and
marketing of high performance application specific integrated circuits and
application specific standard
                                        3

products. Our submicron process technologies, combined with our CoreWare design
methodology, enable us to integrate system level solutions on a single chip. We
tailor our products to the specific application requirements of original
equipment manufacturers and other customers in the following markets:

     - networking,

     - telecom/wireless,

     - consumer,

     - computer,

     - storage components, and

     - storage systems.

     Many of our customers are worldwide leaders in their end markets. Our
customers include:

     - Cisco Systems, Inc.,

     - Compaq Computer Corporation,

     - Hewlett-Packard Company,

     - IBM Corporation,

     - NCR,

     - Sony Corporation, and

     - Sun Microsystems, Inc.

     Since our inception, we have based our technology and our business strategy
on integrating increasingly complex electronic building blocks onto a few chips
or a single chip. High-level, industry-standard building blocks of the type that
were previously independent chips, such as microprocessors, networking
controllers, digital signal processors and video compression engines, are used
as "cores" that are connected electronically, along with a customer's
proprietary logic and memory, to form an entire system on a single chip.
Consequently, our customers achieve higher system performance, lower system cost
and faster time-to-market with a differentiated product.

     We operate our own manufacturing facilities in order to control our
deployment of advanced wafer fabrication technology, our manufacturing costs and
our response to customer delivery requirements. In December 1998, we began
production in a state-of-the-art facility in Gresham, Oregon. The new facility
is equipped for advanced manufacturing operations and designed to accommodate
our expansion requirements well into the foreseeable future. Our production
operations in the United States and Japan, as well as those of our assembly and
test subcontractors in Asia, are ISO certified, an important international
measure for quality.

     We market our products and services worldwide through direct sales,
marketing and field technical staff and through independent sales
representatives and distributors. In addition, we specifically market our
storage system products to original equipment manufacturing and end users
through value added resellers.

     We were originally incorporated in California in 1980. In 1987, we were
reincorporated in Delaware. Our principal offices are located at 1551 McCarthy
Boulevard, Milpitas, California 95035, and our telephone number is (408)
433-8000.

                          GENERAL INDENTURE PROVISIONS

GENERAL INDENTURE PROVISIONS THAT APPLY TO SENIOR AND SUBORDINATED DEBT

     - Neither indenture limits the amount of debt that we may issue or provides
       holders any protection should there be a highly leveraged transaction
       involving our company.


     - The indentures generally allow us to merge, consolidate or convey,
       transfer or lease our properties and assets substantially as an entirety
       to another U.S. company, limited liability company, partnership, trust or
       other business entity, so long as the successor assumes our obligations
       under the indentures and immediately after giving effect to the
       transaction we are not in default under the indentures. If these events
       occur, the other entity will be required to assume our responsibilities
       on the debt, and we will be released from all liabilities and
       obligations, except in the case of a lease.


     - The indentures provide that holders of a majority of the total principal
       amount of the debt outstanding in any series may vote to change our
       obligations or your rights concerning the debt. But to change the payment
       of principal, interest, or adversely effect the right to convert or
       certain other matters, every holder in that series must consent.

     - We may discharge the indentures and defease restrictive covenants by
       depositing sufficient funds with the trustee to pay the obligations when
       due, as long as we are not in default under the indentures at that time.
       All amounts due to you on the debt would be paid by the trustee from the
       deposited funds.

EVENTS OF DEFAULT

     The following are the events of default under the indentures:

     - Principal not paid when due,

     - Sinking fund payment not made when due,

     - Failure to pay interest for 30 days,

     - Covenants not performed for 90 days after notice,


     - Our bankruptcy, insolvency or reorganization, and


     - Any other event of default in the indenture.

REMEDY

     Upon an event of default, other than a bankruptcy, insolvency or
reorganization, the trustee or holders of 25% of the principal amount
outstanding in a series may declare principal immediately payable. However, the
holders of a majority in principal amount may rescind this action.
                                        5
<PAGE>   6

GENERAL INDENTURE PROVISIONS THAT APPLY ONLY TO SENIOR DEBT SECURITIES

     The indenture relating to the senior debt securities contains covenants
restricting our ability to incur secured debt and our ability to sell or
transfer our property to a lender or investor, which then, either directly or
indirectly, leases the property back to us.

GENERAL INDENTURE PROVISIONS THAT APPLY ONLY TO SUBORDINATED DEBT SECURITIES

     The subordinated debt securities will be subordinated to all senior
indebtedness.

                                  RISK FACTORS

     Before you invest in the debt securities or shares of common stock, you
should be aware of various risks, including those described below. You should
carefully consider these risk factors, together with all of the other
information included or incorporated by reference in this prospectus, before you
decide whether to purchase the debt securities or common stock. The risks set
out below are not the only risks we face.

     If any of the following risks occur, our business, financial condition and
results of operations could be materially adversely affected. In such case, the
trading price of the debt securities and common stock could decline, and you may
lose all or part of your investment.

IF WE ARE NOT ABLE TO IMPLEMENT NEW PROCESS TECHNOLOGIES SUCCESSFULLY, OUR
OPERATING RESULTS AND FINANCIAL CONDITION WILL BE ADVERSELY IMPACTED

     The semiconductor industry is intensely competitive and characterized by
constant technological change, rapid product obsolescence and evolving industry
standards. We believe that our future success depends, in part, on our ability
to improve on existing technologies and to develop and implement new ones in
order to continue to reduce semiconductor chip size and improve product
performance and manufacturing yields. We must also adopt and implement emerging
industry standards and adapt products and processes to technological changes. If
we are not able to implement new process technologies successfully or to achieve
volume production of new products at acceptable yields, our operating results
and financial condition will be adversely impacted.

     In addition, we must continue to develop and introduce new products that
compete effectively on the basis of price and performance and that satisfy
customer requirements. We continue to emphasize engineering development and
acquisition of CoreWare building blocks, or cores, and integration of our
CoreWare libraries into our design capabilities. Our cores and ASSPs are
intended to be based upon industry standard functions, interfaces and protocols
so that they are useful in a wide variety of systems applications. Development
of new products and cores often requires long-term forecasting of market trends,
development and implementation of new or changing technologies and a substantial
capital commitment. We cannot assure you that ASSPs or cores that we select for
investment of our financial and engineering resources will be developed or
acquired in a timely manner or will enjoy market acceptance.

DISRUPTION OF OUR MANUFACTURING FACILITIES COULD CAUSE DELAYS IN SHIPMENTS OF
PRODUCTS TO OUR CUSTOMERS AND COULD RESULT IN CANCELLATION OF ORDERS OR LOSS OF
CUSTOMERS

     A variety of reasons, including work stoppages, fire, earthquake, flooding
or other natural disasters, or Year 2000 related problems could cause disruption
of operations at any of our primary manufacturing facilities or at any of our
assembly subcontractors. Although we carry business interruption insurance, the
disruption could result in delays in shipments of products to our customers. We
cannot assure you that alternate production capacity would be available if a
major disruption were to occur, or that if it were available, it could be
obtained on favorable terms. A disruption could result in cancellation of orders
or loss of customers. The loss would result in a material adverse impact on our
operating results and financial condition.

                                        8
<PAGE>   9

OUR LACK OF LONG-TERM VOLUME PRODUCTION CONTRACTS WITH OUR CUSTOMERS COULD
RESULT IN INSUFFICIENT CUSTOMER ORDERS WHICH WOULD RESULT IN UNDERUTILIZATION OF
OUR MANUFACTURING FACILITIES

     We generally do not have long-term volume production contracts with our
customers. We cannot control whether and to what extent customers place orders
for any specific ASIC design or ASSPs and the quantities of products included in
those orders. Insufficient orders will result in underutilization of our
manufacturing facilities and would adversely impact our operating results and
financial condition.

BRINGING OUR NEW WAFER FABRICATION FACILITY TO FULL OPERATING CAPACITY COULD
TAKE LONGER AND COST MORE THAN ANTICIPATED

     Our new wafer fabrication facility in Gresham, Oregon, began production in
December 1998. The Gresham facility is a sophisticated, highly complex,
state-of-the-art factory. Actual production rates depend upon the reliable
operation and effective integration of a variety of hardware and software
components. We cannot assure you that all of these components will be fully
functional or successfully integrated within the currently projected schedule or
that the facility will achieve the forecasted yield targets. Our inability to
achieve and maintain acceptable production capacity and yield levels could have
a material adverse impact on our operating results and financial condition.

     In addition, the amount of capital expenditures required to bring the
facility to full operating capacity could be greater than we currently
anticipate. Higher costs to bring the facility to full operating capacity will
reduce margins and could have a material adverse impact on our results of
operations and financial condition. As of June 30, 1999, we have spent
approximately $789 million in capital expenditures on the Gresham facility. We
plan to spend no more than $250 million in capital expenditures in 1999,
approximately $84 million of which relate to the Gresham facility.

OUR LACK OF GUARANTEED SUPPLY ARRANGEMENTS WITH OUR SUPPLIERS COULD RESULT IN
OUR INABILITY TO OBTAIN SUFFICIENT RAW MATERIALS FOR USE IN THE PRODUCTION OF
OUR PRODUCTS

     We use a wide range of raw materials in the production of our
semiconductors, host adapter boards and storage systems products, including
silicon wafers, processing chemicals, and electronic and mechanical components.
We generally do not have guaranteed supply arrangements with our suppliers and
do not maintain an extensive inventory of materials for manufacturing. Some of
these materials we purchase from a limited number of vendors, and some we
purchase from a single supplier. On occasion, we have experienced difficulty in
securing an adequate volume and quality of materials. We cannot assure you that
if we have difficulty in obtaining materials or components in the future
alternative suppliers will be available, or that available suppliers will
provide materials and components in a timely manner or on favorable terms. If we
cannot obtain adequate materials for manufacture of products, there could be a
material impact on our operating results and financial condition.

HIGH CAPITAL REQUIREMENTS AND HIGH FIXED COSTS CHARACTERIZE OUR BUSINESS, AND WE
FACE A RISK THAT REQUIRED CAPITAL MIGHT BE UNAVAILABLE WHEN WE NEED IT

     In order to remain competitive, we must continue to make significant
investments in new facilities and capital equipment. We spent $330 million in
1998 and $29 million in the

                                        9
<PAGE>   10

first two fiscal quarters of 1999, net of retirements and refinancings, on
investments in new facilities and capital equipment, not including facilities
and capital equipment acquired with Symbios. We expect to spend no more than
$250 million during 1999. We expect to continue to make significant investments
in new facilities and capital equipment. We believe that we will be able to meet
our operating and capital requirements and obligations for the foreseeable
future using existing liquid resources, funds generated from our operations and
our ability to borrow funds. We believe that our level of liquid resources is
important, and we may seek additional equity or debt financing from time to
time. However, we cannot assure you that additional financing will be available
when needed or, if available, will be on favorable terms. Moreover, any future
equity or convertible debt financing will decrease existing stockholders'
percentage equity ownership and may result in dilution, depending on the price
at which the equity is sold or the debt is converted. In addition, the high
level of capital expenditures required to remain competitive results in
relatively high fixed costs. If demand for our products does not absorb
additional capacity, the fixed costs and operating expenses related to increases
in our production capacity could have a material adverse impact on our operating
results and financial condition.

THE NATURE OF OUR INDUSTRY COULD CREATE FLUCTUATIONS IN OUR OPERATING RESULTS
WHICH COULD RESULT IN A SUDDEN AND SIGNIFICANT DROP IN THE PRICE OF OUR STOCK
AND OTHER SECURITIES, PARTICULARLY ON A SHORT-TERM BASIS

     Future operating results will continue to be subject to quarterly
variations based upon a wide variety of factors including:

     - The cyclical nature of both the semiconductor industry and the markets
       addressed by our products,

     - The availability and extent of utilization of manufacturing capacity,

     - Erosion in the price of our products, and

     - The timing of new product introductions, the ability to develop and
       implement new technologies and other competitive factors.

     Operating results could also be impacted by sudden fluctuations in customer
requirements, currency exchange rate fluctuations and other economic conditions
affecting customer demand and the cost of operations in one or more of the
global markets in which we do business.


     We operate in a technologically advanced, rapidly changing and highly
competitive environment, and we predominantly sell custom products to customers
operating in a similar environment. Accordingly, changes in the conditions of
any of our customers may have a greater impact on our operating results and
financial condition than if we predominantly offered standard products that
could be sold to many purchasers. While we cannot predict what effect these
various factors may have on our financial results, their aggregate effect could
result in significant volatility in future performance and the trading prices of
our common stock and other securities. Our failure to meet the performance
expectations published by external sources could result in a sudden and
significant drop in the price of our common stock, and other securities,
particularly on a short-term basis.


                                       10

IF WE ARE UNABLE TO COMPETE EFFECTIVELY WITH EXISTING OR NEW COMPETITORS,
RESULTING LOSS OF COMPETITIVE POSITION COULD RESULT IN PRICE REDUCTIONS, FEWER
CUSTOMER ORDERS, REDUCED REVENUES, REDUCED GROSS MARGINS AND LOST MARKET SHARE

     We compete in markets that are intensely competitive, and which exhibit
both rapid technological changes and continued price erosion. Our competitors
include many large domestic and foreign companies that have substantially
greater financial, technical and management resources than us. Several major
diversified electronics companies offer ASIC products and/or other products that
are competitive with our product lines. Other competitors are smaller,
specialized and emerging companies attempting to sell products in particular
markets that we also target. In addition, we face competition from some
companies whose strategy is to provide a portion of the products and services
that we offer. For example, these competitors may offer semiconductor design
services, license design tools, and/or provide support for obtaining products at
an independent foundry. Some of our large customers, some of whom may have
licensed elements of our process and product technologies, may develop internal
design and production operations to produce their own ASICs, thereby displacing
our products. Therefore, we cannot assure you that we will be able to continue
to compete effectively with our existing or new competitors. Loss of competitive
position could result in price reductions, fewer customer orders, reduced
revenues, reduced gross margins, and loss of market share, any of which would
affect our operating results and financial condition.

     To remain competitive, we continue to evaluate our worldwide manufacturing
operations, looking for additional cost savings and technological improvements.
If we are not able to implement successfully new process technologies and to
achieve volume production of new products at acceptable yields, our operating
results and financial condition may be affected.

     Our future competitive performance depends on a number of factors,
including our ability to:

     - Accurately identify emerging technological trends and demand for product
       features and performance characteristics,

     - Develop and maintain competitive products,

     - Enhance our products by adding innovative features that differentiate our
       products from those of our competitors,

     - Bring products to market on a timely basis at competitive prices,

     - Properly identify target markets,

     - Respond effectively to new technological changes or new product
       announcements by others,

     - Reduce semiconductor chip size, increase device performance and improve
       manufacturing yields,

     - Adapt products and processes to technological changes, and

     - Adopt and/or set emerging industry standards.

     We cannot assure you that our design, development and introduction
schedules for new products or enhancements to our existing and future products
will be met. In addition, we cannot assure you that these products or
enhancements will achieve market acceptance, or that we will be able to sell
these products at prices that are favorable to us.

                                       11

OUR SIGNIFICANT INVESTMENTS IN RESEARCH AND DEVELOPMENT BEFORE WE CONFIRM THE
TECHNICAL FEASIBILITY AND COMMERCIAL VIABILITY OF A PRODUCT PRESENT RISKS THAT
WE WILL BE UNABLE TO RECOVER THE DEVELOPMENT COSTS ASSOCIATED WITH SUCH PRODUCT

     We must continue to make significant investments in research and
development in order to continually enhance the performance and functionality of
our products, to keep pace with competitive products and to satisfy customer
demands for improved performance, features and functionality. Technical
innovations are inherently complex and require long development cycles and
appropriate professional staffing. We must complete development of such
innovations before they are obsolete, and make them sufficiently compelling to
attract customers. Also, we must incur substantial research and development
costs before we confirm the technical feasibility and commercial viability of a
product. Therefore, we spend substantial resources determining the feasibility
of certain innovations that may not lead to a product but may instead result in
numerous dead ends and sunk costs. We cannot assure you that revenues from
future products or product enhancements will be sufficient to recover the
development costs associated with such products or enhancements. Moreover, we
may not be able to secure the financial resources necessary to fund future
development.

OUR ACQUISITION AND INVESTMENT ALLIANCE ACTIVITIES COULD DISRUPT OUR ONGOING
BUSINESS

     We intend to continue to make investments in companies, products and
technologies, either through acquisitions or investment alliances. We are
currently evaluating potential acquisition and investment alliances and will
continue to do so on an ongoing basis. We do not currently have any commitments
for a material acquisition or investment alliance. Acquisitions and investment
activities often involve risks, including:

     - We may experience difficulty in assimilating the acquired operations and
       employees,

     - We may be unable to retain the key employees of the acquired operation,

     - The acquisition or investment may disrupt our ongoing business,

     - We may not be able to incorporate successfully the acquired technology
       and operations into our business and maintain uniform standards,
       controls, policies and procedures, and

     - We may lack the experience to enter into new markets, products or
       technologies.

     Some of these factors are beyond our control. Failure to manage growth
effectively and to integrate acquisitions would affect our operating results or
financial condition.

CHANGES IN FOREIGN CURRENCY EXCHANGE RATES COULD AFFECT OUR OPERATIONS OR CASH
FLOWS

     We have international subsidiaries that operate and sell our products
globally. Our international sales totaled approximately $560 million in 1998 and
$373 million in the first two fiscal quarters of 1999. Further, we purchase a
substantial portion of our raw materials and equipment from foreign suppliers,
and we incur labor and other operating costs in foreign currencies, particularly
in our Japanese manufacturing facilities. As a result, we are exposed to changes
in foreign currency exchange rates or weak economic conditions in the other
countries.

                                       12
<PAGE>   13

     Our debt obligations in Japan totaled approximately 8.6 billion yen,
approximately $71 million, at June 30, 1999. These obligations expose us to
exchange rate fluctuations for the period of time from the start of the
transaction until it is settled. In recent years, the yen has fluctuated
substantially against the U.S. dollar. We use forward exchange, currency swap,
interest rate swap and option contracts to manage our exposure to currency
fluctuations and changes in interest rates. There were no interest rate swap or
currency swap contracts outstanding as of June 30, 1999. We cannot assure you,
however, that such hedging transactions will eliminate exposure to currency rate
fluctuations and changes in interest rates. Notwithstanding our efforts to
foresee and mitigate the effects of changes in fiscal circumstances,
fluctuations in currency exchange rates in the future could affect our
operations and/or cash flows. In addition, high inflation rates in foreign
countries could affect our future results.

IF WE DO NOT SUCCESSFULLY COMPLETE MODIFICATIONS TO OUR SYSTEMS AND COMMERCIAL
ARRANGEMENTS IN A TIMELY MANNER TO ACCOMMODATE THE NEW EUROPEAN CURRENCY,
MATERIAL DISRUPTION OF OUR BUSINESS COULD OCCUR

     A new European currency was implemented in January 1999 to replace the
separate currencies of eleven western European countries. In response, we are
changing our operations as we modify systems and commercial arrangements to deal
with the new currency. Modifications are necessary in operations such as
payroll, benefits and pension systems, contracts with suppliers and customers,
and internal financial reporting systems. We expect a three-year transition
period during which transactions may also be made in the old currencies. This
requires dual currency processes for our operations. We have identified issues
involved and are developing and implementing solutions. The cost of this effort
is not expected to have a material effect on our business or results of
operations. We cannot assure you, however, that all problems will be foreseen
and corrected or that no material disruption of our business will occur.

CHANGES IN INTERNATIONAL TRADE AND ECONOMIC CONDITIONS COULD ADVERSELY IMPACT
OUR ABILITY TO MANUFACTURE OR SELL IN FOREIGN MARKETS AND COULD RESULT IN A
DECLINE IN CUSTOMER ORDERS

     We have substantial business activities in Europe and the Pan-Asia region.
Both manufacturing and sales of our products may be adversely impacted by
changes in political and economic conditions abroad. A change in the current
tariff structures, export compliance laws or other trade policies, in either the
United States or foreign countries could adversely impact our ability to
manufacture or sell in foreign markets.

     The recent economic crisis in Asia has affected business conditions and
pricing in the region. We subcontract test and assembly functions to
subcontractors in Asia. A significant reduction in the number or capacity of
qualified subcontractors or a substantial increase in pricing could cause longer
lead times, delays in the delivery of customer orders or increased costs. Such
conditions could have an adverse impact on our operating results. Additionally,
our customers sell products, especially consumer products, into the Pan-Asia
region. A significant decrease in sales to end-users and consumers in the area
could result in a decline in orders and have an impact on our operating results
and financial condition.

                                       13
<PAGE>   14

OUR MARKETING STRATEGY CREATES RISKS ASSOCIATED WITH CUSTOMER CONCENTRATION

     We expect that we will become increasingly dependent on a limited number of
customers for a substantial portion of our net revenues. This is as a result of
our strategy to direct our marketing and selling efforts toward selected
customers. During 1998, Sony Corporation accounted for 12% of net revenues. We
fill Sony's orders as they are placed and accepted. We do not have a supply
contract with Sony and Sony is not obligated to purchase our products.

     Our operating results and financial condition could be affected if:

     - We do not win new product designs from major customers,

     - Major customers cancel their business with us,

     - Major customers make significant changes in scheduled deliveries, or

     - Prices of products that we sell to these customers are decreased.

OUR BUSINESS AS A HIGH TECHNOLOGY COMPANY PRESENTS RISKS OF INTELLECTUAL
PROPERTY OBSOLESCENCE, INFRINGEMENT AND LITIGATION

     Our success is dependent in part on our technology and other proprietary
rights. We believe that there is value in the protection afforded by our
patents, patent applications and trademarks. However, the semiconductor industry
is characterized by rapidly changing technology. Our future success depends
primarily on the technical competence and creative skills of our personnel,
rather than on patent and trademark protection.

     As is typical in the semiconductor industry, from time to time we have
received communications from other parties asserting that they possess patent
rights, mask work rights, copyrights, trademark rights or other intellectual
property rights which cover certain of our products, processes, technologies or
information. We are evaluating several such assertions. We are considering
whether to seek licenses with respect to certain of these claims. Based on
industry practice, we believe that licenses or other rights, if necessary, could
be obtained on commercially reasonable terms for existing or future claims.
Nevertheless, we cannot assure you that licenses can be obtained, or if obtained
will be on acceptable terms or that litigation or other administrative
proceedings will not occur. Litigation of such claims or the inability to obtain
certain licenses or other rights or to obtain such licenses or rights on
favorable terms could have an impact on our operating results and financial
condition.

CYCLICAL FLUCTUATIONS IN OUR MARKETS COULD CAUSE A DOWNTURN IN DEMAND FOR OUR
PRODUCTS AND RESULT IN LOWER REVENUES

     We may experience period-to-period fluctuations or a decline as a result of
the following:

     - Rapid technological change, rapid product obsolescence, and price erosion
       in our products,

     - Fluctuations in supply and demand in the semiconductor or storage markets
       for our products,

     - Maturing product cycles in our products or products produced by our
       customers, and

                                       14
<PAGE>   15

     - Fluctuations or declines in general economic conditions, which often
       produce abrupt fluctuations or declines in our products or the products
       or services offered by our suppliers and customers.

     Significant industry-wide fluctuations or a downturn as a result of these
factors could affect our operating results and financial condition.

     The semiconductor industry also has experienced periods of rapid expansion
of production capacity. Even if our customers' demand were not to decline, the
availability of additional excess production capacity in our industry creates
competitive pressure that can degrade pricing levels, which can also depress our
revenues. Also, during such periods, customers who benefit from shorter lead
times may delay some purchases into future periods, which could affect our
demand and revenues for the short term. We cannot assure you that we will not
experience such downturns or fluctuations in the future, which could affect our
operating results and financial condition.

WE DEPEND ON KEY EMPLOYEES AND FACE COMPETITION IN HIRING AND RETAINING
QUALIFIED EMPLOYEES

     Our employees are vital to our success. Moreover, our key management,
engineering and other employees are difficult to replace. We generally do not
have employment contracts with our key employees. Further, we do not maintain
key person life insurance on any of our employees. The expansion of high
technology companies in Silicon Valley and Colorado has increased demand and
competition for qualified personnel. We may not be able to attract, assimilate
or retain additional highly qualified employees in the future. These factors
could affect our business, financial condition and results of operations.

IF WE, OUR SUPPLIERS OR OUR CUSTOMERS DO NOT SUCCESSFULLY, TIMELY OR ADEQUATELY
ADDRESS THE YEAR 2000 ISSUE, WE COULD EXPERIENCE A SIGNIFICANT DISRUPTION OF OUR
FINANCIAL MANAGEMENT AND CONTROL SYSTEMS OR A LENGTHY INTERRUPTION IN OUR
MANUFACTURING OPERATIONS

     As with many other companies, the Year 2000 computer issue presents risks
for us. We use a significant number of computer software programs and operating
systems in our internal operations, including applications used in our
financial, product development, order management and manufacturing systems.

     The inability of computer software programs to accurately recognize,
interpret and process date codes designating the year 2000 and beyond could
cause systems to yield inaccurate results or encounter operating problems
resulting in the interruption of the business operations which they control.
This could adversely affect our ability to process orders, forecast production
requirements or issue invoices. A significant failure of the computer integrated
manufacturing systems, which monitor and control factory equipment, would
disrupt manufacturing operations and cause a delay in completion and shipping of
products. Moreover, if our critical suppliers' or customers' systems or products
fail because of a Year 2000 malfunction, it could impact our operating results.
Finally, our own products could malfunction as a result of a failure in date
recognition, giving rise to the possibility of warranty claims and litigation.

     Based on currently available information, our management does not believe
that the Year 2000 issues discussed above, related to internal systems or
products sold to customers, will have a material impact on our financial
condition or overall trends in

                                       15
<PAGE>   16

results of operations. However, we are uncertain to what extent we may be
affected by such matters. A significant disruption of our financial management
and control systems or a lengthy interruption in our manufacturing operations
caused by a Year 2000 related issue could result in a material adverse impact on
our operating results and financial condition. In addition, it is possible that
a supplier's failure to ensure Year 2000 capability or our customer's concerns
about Year 2000 readiness of our products would have a material adverse effect
on our results of operations.

OUR ABILITY TO REPAY THE DEBT SECURITIES IS DEPENDENT IN PART ON THE EARNINGS OF
OUR SUBSIDIARIES

     The debt securities are exclusively obligations of LSI Logic Corporation. A
substantial portion of our operations are conducted through our subsidiaries. As
a result, our cash flow and our ability to service our debt, including the debt
securities, is dependent upon the earnings of our subsidiaries. In addition, we
are dependent on the distribution of earnings, loans or other payments by our
subsidiaries to us.

     Our subsidiaries are separate and distinct legal entities. Our subsidiaries
have no obligation to pay any amounts due on the debt securities. Our
subsidiaries are not required to provide us with funds for our payment
obligations, whether by dividends, distributions, loans or other payments. In
addition, any payment of dividends, distributions, loans or advances by our
subsidiaries to us could be subject to statutory or contractual restrictions.
Payments to us by our subsidiaries will also be contingent upon our
subsidiaries' earnings and business considerations.

     Our right to receive any assets of any of our subsidiaries upon their
liquidation or reorganization, and therefore the right of the holders to
participate in those assets, will be effectively subordinated to the claims of
that subsidiary's creditors, including trade creditors. In addition, even if we
were a creditor to any of our subsidiaries, our rights as a creditor would be
subordinate to any security interest in the assets of our subsidiaries and any
indebtedness of our subsidiaries senior to that held by us.

POSSIBLE VOLATILITY OF PRICE OF COMMON STOCK

     The market price of our common stock has been volatile in the past and may
be volatile in the future. The trading price of the common stock may be
significantly affected by the following factors:

     - The cyclical nature of both the semiconductor industry and the markets
       addressed by our products,

     - The availability and extent of utilization of manufacturing capacity,

     - Erosion in the price of our products,

     - The timing of new product introductions, the ability to develop and
       implement new technologies and other competitive factors,

     - Our announcement of new products or product enhancements or similar
       announcements by our competitors, and

     - General market conditions or market conditions specific to particular
       industries.

     In addition, the stock prices of many companies in the technology and
emerging growth sectors have fluctuated widely due to events unrelated to their
operating performance. These fluctuations may adversely affect the market price
of our common stock.

                                       16

                                USE OF PROCEEDS

     Unless otherwise indicated in the applicable prospectus supplement, we
anticipate that any net proceeds from the sale of securities offered by this
prospectus will be used to fund expansion of our business, including for:

     - additional working capital,

     - capital expenditures,

     - repayment of existing indebtedness,

     - acquisitions of products, technologies and businesses, and

     - general corporate purposes.

     When we offer a particular series of securities offered by this prospectus,
the prospectus supplement relating to that offering will set forth the intended
use of the net proceeds received from that offering. Pending the application of
the net proceeds, we expect to invest the proceeds from the sale of offered
securities in interest-bearing securities.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The ratio of earnings to fixed charges for each of the periods indicated is
as follows:

</TABLE>


     These computations include us and our consolidated subsidiaries. Ratio of
earnings to fixed charges is computed by dividing (i) earnings before taxes
adjusted for fixed charges, minority interest and capitalized interest net of
amortization by (ii) fixed charges, which includes interest expense and
capitalized interest incurred, plus the portion of interest expense under
operating leases deemed by us to be representative of the interest factor, plus
amortization of debt issuance costs. In 1998, earnings were inadequate to cover
fixed charges by $140 million.


     Our fiscal years ended on December 31, 1997 and 1998, and the Sunday
closest to December 31, in 1994, 1995 and 1996. For presentation purposes, this
prospectus refers to December 31 as our fiscal year end.

                       DESCRIPTION OF THE DEBT SECURITIES

     The debt securities will either be our senior debt securities or our
subordinated debt securities. The debt securities will be issued under one or
more separate indentures between us and State Street Bank and Trust Company of
California, N.A., as trustee. Senior debt securities will be issued under a
senior indenture and subordinated debt securities will be issued under a
subordinated indenture. Together, the senior indenture and subordinated
indenture are called indentures. The prospectus, together with its prospectus
supplement, will describe all the material terms of a particular series of debt
securities.

                                       17
<PAGE>   18

     The following is a summary of the most important provisions and definitions
of the indentures. For additional information, you should look at the applicable
indenture that is filed as an exhibit to the registration statement which
includes this prospectus. In this description of the debt securities, the words
"LSI", "we", "us" or "our" refer only to LSI Logic Corporation and not to any of
our subsidiaries.

GENERAL

     Debt securities may be issued in separate series without limitation as to
aggregate principal amount. We may specify a maximum aggregate principal amount
for the debt securities of any series. We are not limited as to the amount of
debt securities we may issue under the indentures.

     The prospectus supplement will set forth:

     - whether the debt securities are senior or subordinated,

     - the offering price,

     - the title,

     - any limit on the aggregate principal amount,

     - the person who shall be entitled to receive interest, if other than the
       record holder on the record date,

     - the date the principal will be payable,

     - the interest rate, if any, the date interest will accrue, the interest
       payment dates and the regular record dates,

     - the place where payments shall be made,

     - any mandatory or optional redemption provisions,

     - if applicable, the method for determining how principal, premium, if any,
       or interest will be calculated by reference to an index or formula,

     - if other than U.S. currency, the currency or currency units in which
       principal, premium, if any, or interest will be payable and whether we or
       the holder may elect payment to be made in a different currency,

     - the portion of the principal amount that will be payable upon
       acceleration of stated maturity, if other than the entire principal
       amount,

     - if the principal amount payable at stated maturity will not be
       determinable as of any date prior to stated maturity, the amount which
       will be deemed to be the principal amount,

     - any defeasance provisions if different from those described below under
       "Satisfaction and Discharge -- Defeasance,"

     - any conversion or exchange provisions,

     - whether the debt securities will be issuable in the form of a global
       security,

                                       18
<PAGE>   19

     - any subordination provisions if different from those described below
       under "Subordinated Debt Securities,"

     - any deletions of, or changes or additions to, the events of default or
       covenants, and

     - any other specific terms of such debt securities.

     Unless otherwise specified in the prospectus supplement:

     - the debt securities will be registered debt securities; and

     - registered debt securities denominated in U.S. dollars will be issued in
       denominations of $1,000 or an integral multiple of $1,000.

     Debt securities may be sold at a substantial discount below their stated
principal amount, bearing no interest or interest at a rate which at time of
issuance is below market rates.

EXCHANGE AND TRANSFER

     Debt securities may be transferred or exchanged at the office of the
security registrar or at the office of any transfer agent designated by us. We
will not impose a service charge for any transfer or exchange, but we may
require holders to pay any tax or other governmental charges associated with any
transfer or exchange.

     In the event of any potential redemption of debt securities of any series,
we will not be required to:

     - issue, register the transfer of, or exchange, any debt security of that
       series during a period beginning at the opening of business 15 days
       before the day of mailing of a notice of redemption and ending at the
       close of business on the day of the mailing, or

     - register the transfer of or exchange any debt security of that series
       selected for redemption, in whole or in part, except the unredeemed
       portion being redeemed in part.

     We have initially appointed the trustee as the security registrar. Any
transfer agent, in addition to the security registrar, initially designated by
us will be named in the prospectus supplement. We may designate additional
transfer agents or change transfer agents or change the office of the transfer
agent. However, we will be required to maintain a transfer agent in each place
of payment for the debt securities of each series.

GLOBAL SECURITIES

     The debt securities of any series may be represented, in whole or in part,
by one or more global securities. Each global security will:

     - be registered in the name of a depositary that we will identify in a
       prospectus supplement,

     - be deposited with the depositary or nominee or custodian, and

     - bear any required legends.

                                       19
<PAGE>   20

     No global security may be exchanged in whole or in part for debt securities
registered in the name of any person other than the depositary or any nominee
unless:

     - the depositary has notified us that it is unwilling or unable to continue
       as depositary or has ceased to be qualified to act as depositary,

     - an event of default is continuing, or

     - any other circumstances described in a prospectus supplement.

     As long as the depositary, or its nominee, is the registered owner of a
global security, the depositary or nominee will be considered the sole owner and
holder of the debt securities represented by the global security for all
purposes under the indentures. Except in the above limited circumstances, owners
of beneficial interests in a global security will not be:

     - entitled to have the debt securities registered in their names,

     - entitled to physical delivery of certificated debt securities, and

     - considered to be holders of those debt securities under the indenture.

     Payments on a global security will be made to the depositary or its nominee
as the holder of the global security. Some jurisdictions have laws that require
that certain purchasers of securities take physical delivery of such securities
in definitive form. These laws may impair the ability to transfer beneficial
interests in a global security.

     Institutions that have accounts with the depositary or its nominee are
referred to as "participants." Ownership of beneficial interests in a global
security will be limited to participants and to persons that may hold beneficial
interests through participants. The depositary will credit, on its book-entry
registration and transfer system, the respective principal amounts of debt
securities represented by the global security to the accounts of its
participants.

     Ownership of beneficial interests in a global security will be shown on and
effected through records maintained by the depositary, with respect to
participants' interests, or any participant, with respect to interests of
persons held by participants on their behalf.

     Payments, transfers and exchanges relating to beneficial interests in a
global security will be subject to policies and procedures of the depositary.
The depositary's policies and procedures may change from time to time. Neither
we nor the trustee will have any responsibility or liability for the
depositary's or any participant's records with respect to beneficial interests
in a global security.

PAYMENT AND PAYING AGENTS

     The provisions of this paragraph will apply to the debt securities unless
otherwise indicated in the prospectus supplement. Payment of interest on a debt
security on any interest payment date will be made to the person in whose name
the debt security is registered at the close of business on the regular record
date. Payment on debt securities of a particular series will be payable at the
office of a paying agent or paying agents designated by us. However, at our
option, we may pay interest by mailing a check to the record holder. The
corporate trust office will be designated as our sole paying agent.

                                       20
<PAGE>   21

     We may also name any other paying agents in the prospectus supplement. We
may designate additional paying agents, change paying agents or change the
office of any paying agent. However, we will be required to maintain a paying
agent in each place of payment for the debt securities of a particular series.

     All moneys paid by us to a paying agent for payment on any debt security
which remain unclaimed for a period ending the earlier of:

     - 10 business days prior to the date the money would be turned over to the
       state, or

     - at the end of two years after such payment was due

will be repaid to us. Thereafter, the holder may look only to LSI for such
payment.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may not consolidate with or merge into any other person, in a
transaction in which we are not the surviving corporation, or convey, transfer
or lease our properties and assets substantially as an entirety to, any person,
unless:

     - the successor, if any, is a U.S. corporation, limited liability company,
       partnership, trust or other business entity,

     - the successor assumes our obligations on the debt securities and under
       the indentures,

     - immediately after giving effect to the transaction, no default or event
       of default shall have occurred and be continuing, and

     - certain other conditions are met.

EVENTS OF DEFAULT

     Each indenture defines an event of default with respect to any series of
debt securities as one or more of the following events:

          (1) failure to pay principal of or any premium on any debt security of
     that series when due,

          (2) failure to pay any interest on any debt security of that series
     for 30 days when due,

          (3) failure to deposit any sinking fund payment when due,

          (4) failure to perform any other covenant in the indenture continued
     for 90 days after being given the notice required in the indenture,

          (5) our bankruptcy, insolvency or reorganization, and


          (6) any other event of default specified in the prospectus supplement.


     An event of default of one series of debt securities is not necessarily an
event of default for any other series of debt securities.

     If an event of default, other than an event of default described in clause
(5) above, occurs and continues, either the trustee or the holders of at least
25% in aggregate

                                       21
<PAGE>   22

principal amount of the outstanding securities of that series may declare the
principal amount of the debt securities of that series to be due and payable
immediately. If an event of default described in clause (5) above occurs, the
principal amount of all the debt securities of that series, will automatically
become immediately due and payable. Any payment by us on the subordinated debt
securities following any acceleration will be subject to the subordination
provisions described below under "Subordinated Debt Securities."

     After acceleration the holders of a majority in aggregate principal amount
of the outstanding securities of that series may, under certain circumstances,
rescind and annul such acceleration if all events of default, other than the
non-payment of accelerated principal, or other specified amount, have been cured
or waived.

     Other than the duty to act with the required care during an event of
default, the trustee will not be obligated to exercise any of its rights or
powers at the request of the holders unless the holders offer the trustee
reasonable indemnity. Generally, the holders of a majority in aggregate
principal amount of the outstanding debt securities of any series 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.

     A holder will have the right to begin a proceeding under the indentures, or
for the appointment of a receiver or a trustee, or for any other remedy under
the indentures only if:

          (1) the holder has previously given to the trustee written notice of a
     continuing event of default with respect to the debt securities of that
     series,

          (2) the holders of at least 25% in aggregate principal amount of the
     outstanding debt securities of that series have made a written request and
     have offered reasonable indemnity to the trustee to begin the proceeding,

          (3) the trustee has not started the proceeding within 60 days after
     the request, and

          (4) the trustee has not received direction inconsistent with the
     original request from the holders of a majority in aggregate principal
     amount of the outstanding debt securities of that series within 60 days
     after the original request.


     Holders may, however, sue to enforce the payment of principal, premium or
interest on or after the due date or their right to convert without following
the procedures listed in (1) through (4) above.


     We will furnish the trustee an annual statement by our officers as to
whether or not we are in default in the performance of the indenture and, if so,
specifying all known defaults.

MODIFICATION AND WAIVER

     We and the trustee may make modifications and amendments to the indentures
with the consent of the holders of a majority in aggregate principal amount of
the outstanding securities of each series affected by the modification or
amendment.

                                       22
<PAGE>   23

     However, neither we nor the trustee may make any modification or amendment
without the consent of the holder of each outstanding security of that series
affected by the modification or amendment if such modification or amendment
would:

     - change the stated maturity of any debt security,

     - reduce the principal, premium, if any, or interest on any debt security,

     - reduce the principal of an original issue discount security or any other
       debt security payable on acceleration of maturity,

     - change the place of payment or the currency in which any debt security is
       payable,

     - impair the right to sue for any payment after the stated maturity or
       redemption date,

     - if subordinated debt securities, modify the subordination provisions in a
       materially adverse manner to the holders,

     - adversely affect the right to convert any debt security, or

     - change the provisions in the indenture that relate to modifying or
       amending the indenture.

SATISFACTION AND DISCHARGE; DEFEASANCE

     We may be discharged from our obligations on the debt securities of any
series that have matured or will mature or be redeemed within one year if we
deposit with the trustee enough cash to pay all the principal, interest and any
premium due to the stated maturity date or redemption date of the debt
securities.

     Each indenture contains a provision that permits us to elect:

     - to be discharged from all of our obligations, subject to limited
       exceptions, with respect to any series of debt securities then
       outstanding; and/or

     - to be released from our obligations under the following covenants and
       from the consequences of an event of default resulting from a breach of
       these covenants:

          (1) the limitations on sale and leaseback transactions under the
     senior indenture,

          (2) the limitations on secured debt under the senior indenture,

          (3) the subordination provisions under the subordinated indenture, and

          (4) covenants as to payment of taxes and maintenance of properties.

     To make either of the above elections, we must deposit in trust with the
trustee enough money to pay in full the principal, interest and premium on the
debt securities. This amount may be made in cash and/or U.S. government
obligations. As a condition to either of the above elections, we must deliver to
the trustee an opinion of counsel that the holders of the debt securities will
not recognize income, gain or loss for Federal income tax purposes as a result
of the action.

     If we elect to be discharged from all of our obligations as outlined above
in the first bullet point in this section, the holders of the debt securities of
the series will not be

                                       23
<PAGE>   24

entitled to the benefits of the indenture, except for registration of transfer
and exchange of debt securities and replacement of lost, stolen or mutilated
debt securities.

NOTICES

     Notices to holders will be given by mail to the addresses of the holders in
the security register.

GOVERNING LAW

     The indentures and the debt securities will be governed by, and construed
under, the law of the State of New York, without regard to conflicts of laws
principles.

REGARDING THE TRUSTEE

     The indentures limit the right of the trustee, should it become a creditor
of LSI, to obtain payment of claims or secure its claims.

     The trustee is permitted to engage in certain other transactions. However,
if the trustee acquires any conflicting interest, and there is a default under
the debt securities of any series for which they are trustee, the trustee must
eliminate the conflict or resign.

SENIOR DEBT SECURITIES

     The senior debt securities will be unsecured and will rank equally with all
of our other unsecured and non-subordinated senior debt.

Covenants in the Senior Indenture

     Limitations on Liens. Neither we nor any restricted subsidiary will issue,
incur, create, assume or guarantee any secured debt without securing the senior
debt securities equally and ratably with or prior to that secured debt unless
the total amount of all secured debt that the senior debt securities are not
secured equally and ratably with, would not exceed the greater of $300 million
or 10% of our consolidated net tangible assets.

     Limitations on Sale and Lease-back Transactions. Subject to the last
paragraph of this Section, neither we nor any restricted subsidiary will enter
into any lease longer than three years covering any of our principal property or
any restricted subsidiary that is sold to any other person in connection with
that lease unless either:

          (1) we or any restricted subsidiary would be entitled to incur
     indebtedness secured by a mortgage on the principal property involved in
     such transaction at least equal in amount to the attributable debt with
     respect to the lease, without equally and ratably securing the senior debt
     securities, pursuant to "Limitation on Liens" described above, or

          (2) an amount equal to the greater of the following amounts is applied
     within 180 days to the retirement of our or any restricted subsidiary's
     long-term debt or the purchase or development of comparable property:

     - the net proceeds from the sale; and

     - the attributable debt with respect to the sale and leaseback transaction.

                                       24
<PAGE>   25

     However, either we or our restricted subsidiaries would be able to enter
into a sale and lease back transaction without being required to apply the net
proceeds from this sale and lease back transaction as required by (2) above if
the sum of the following amounts would not exceed the greater of $300 million or
10% of our consolidated net tangible assets:

     - the total amount of the sale and leaseback transactions, and

     - the total amount of secured debt.


     Absence of Certain Covenants. The prospectus supplement will specify any
additional restrictive covenants applicable to the senior debt securities. The
senior indenture does not contain provisions permitting the holders of senior
debt securities to require us to repurchase or redeem the senior debt securities
in the event of a takeover, recapitalization or similar restructuring, highly
leveraged transaction, or any downgrading of our debt ratings.


Definitions

     "attributable debt" with regard to a sale and leaseback transaction means
the lesser of:

          (1) the fair market value of such property as determined in good faith
     by our board of directors, or

          (2) discounted present value of all net rentals under the lease.

       to the proceeds or the project financed with the proceeds of the
       transaction.

     "principal property" means the land, improvements, buildings and fixtures
owned by us or a subsidiary located in the United States that constitutes our

     "secured debt" means any of our debt or any debt of a restricted subsidiary
for borrowed money secured by a mortgage on any principal property or any stock

       (including leases), or mortgages to secure payment of all or any part of
       the purchase price, or to secure any debt within 270 days after the
       acquisition thereof, or in the case of property, the completion of
       construction, improvement or commencement of substantial commercial

     - mortgages constituting any extension, renewal or replacement of any

SUBORDINATED DEBT SECURITIES

     The indebtedness evidenced by the subordinated debt securities is
subordinated to the extent provided in the subordinated indenture to the prior
payment in full in cash or other payment satisfactory to holders of senior
indebtedness of all senior indebtedness, including

                                       26
<PAGE>   27

any senior debt securities, and will rank equally with our outstanding 4 1/4%
convertible subordinated notes due 2004.

     Upon any distribution of our assets upon any dissolution, winding up,
liquidation or reorganization, payments on the subordinated debt securities will
be subordinated in right of payment to the prior payment in full in cash or
other payment satisfactory to holders of senior indebtedness of all senior
indebtedness.


     In the event of any acceleration of the subordinated debt securities
because of an event of default, holders of any senior indebtedness would be
entitled to payment in full in cash or other payment satisfactory to holders of
senior indebtedness of all senior indebtedness before the holders of
subordinated debt securities are entitled to receive any payment or
distribution.



     We are required to promptly notify holders of senior indebtedness if
payment of the subordinated debt securities is accelerated because of an event
of default.


     As a result of these subordination provisions, in the event of our
bankruptcy, dissolution or reorganization, holders of senior indebtedness may
receive more, ratably, and holders of the subordinated debt securities may
receive less, ratably, than our other creditors.


     We may also not make payment on the subordinated debt securities if:



     - a default in the payment of senior indebtedness occurs and is continuing
       beyond any grace period,



     - any other default occurs and is continuing with respect to designated
       senior indebtedness that permits holders or their representatives of
       designated senior indebtedness to accelerate its maturity, and the
       trustee receives a payment blockage notice from us or some other person
       permitted to give the notice under the subordinated indenture, or


     - any judicial proceeding shall be pending with respect to any payment
       default or non-payment default.

     We may and shall resume payments on the subordinated debt securities:


     - in case of a payment default, the date on which the default is cured or
       waived or ceases to exist, and



     - in case of a nonpayment default, the earlier of the date on which the
       default is cured or waived or ceases to exist or 179 days after the
       receipt of the payment blockage notice.


     No new payment blockage period may start unless 365 days have elapsed from
the effectiveness of the prior payment blockage notice.

     No nonpayment default that existed or was continuing on the date of
delivery of any payment blockage notice to the trustee shall be the basis for a
subsequent payment blockage notice.

     The subordination provisions will not prevent the occurrence of any event
of default under the subordinated indenture.

                                       27
<PAGE>   28


     Senior debt securities will constitute senior indebtedness under the
subordinated indenture.



     If the Trustee, any paying agent or any holder receives any payment or
distribution of assets in contravention of these subordination provisions before
all senior indebtedness is paid in full in cash or other payment satisfactory to
holders of senior indebtedness, then such payment or distribution will be held
in trust for the holders of senior indebtedness to the extent necessary to make
payment in full in cash or payment satisfactory to the holders of senior
indebtedness of all unpaid senior indebtedness.


Definitions


     "designated senior indebtedness" means senior indebtedness under our
existing credit facility and any other senior indebtedness that expressly
provides that it is "designated senior indebtedness."


     "indebtedness" means:

          (1) all obligations


             - for borrowed money,



             - evidenced by a note, debenture, bond or written instrument,



             - in respect of leases required, in conformity with generally
               accepted accounting principles, to be accounted for as
               capitalized lease obligations on the balance sheet,


             - all obligations and other liabilities under any lease or related
               document in connection with the lease of real property which
               provides that such person is contractually obligated to purchase
               or cause a third party to purchase the leased property and as a
               result guarantee a minimum residual value of the leased property
               to the lessor and the obligations of such person under such lease
               or related document to purchase or to cause a third party to
               purchase such leased property, or

             - in respect of letters of credit, local guarantees or bankers'
               acceptances;


          (2) all obligation of others of the type described in clause (1) above

              cap, floor and collar agreements, spot and forward contracts and
              similar agreements and arrangements; and

          (5) all deferrals or renewals of (1) through (4) above.

     "senior indebtedness" means the principal, premium, if any, and interest,
including bankruptcy interest and fees, and rent payable on all our
indebtedness, whether outstanding on the date of the indenture or thereafter
created, incurred, assumed, guaranteed or in effect guaranteed by us, including
all renewals or extensions.

                                       28
<PAGE>   29

     However, senior indebtedness shall not include:

          - indebtedness evidenced by the subordinated debt securities,


          - our 4 1/4% convertible subordinated debentures due 2004,



          - indebtedness to any of our subsidiaries, except if it is pledged as
            security for any senior indebtedness,


          - our accounts payable to trade creditors arising in the ordinary
            course of business, and

          - any indebtedness that expressly provides that it shall not be senior
            in right of payment to, or on the same basis with, or is
            subordinated or junior to, the subordinated debt securities.

                          DESCRIPTION OF CAPITAL STOCK

     Our authorized capital stock consists of 450,000,000 shares of common
stock, par value $0.01 per share, and 2,000,000 shares of preferred stock, par
value $0.01 per share.

     COMMON STOCK. As of August 7, 1999, there were 147,622,560 shares of common
stock outstanding held by approximately 2,907 holders of record. Each holder of
common stock is entitled to one vote per share on all matters to be voted upon
by the stockholders. Our certificate of incorporation provides that at all
elections of directors, each holder of stock shall be entitled to cumulative
voting. The holder may cast all of these votes for a single candidate or may
distribute them among the number of directors to be elected. Holders of common
stock are entitled to receive dividends declared by the board of directors, out
of funds legally available for the payment of dividends subject to preferences
that may be applicable to the holders of preferred stock. Upon liquidation,
dissolution or winding up of our business, the holders of common stock are
entitled to share equally in all assets available for distribution after payment
of liabilities, subject to prior distribution rights of preferred stock. The
holders of common stock have no preemptive or conversion rights or other
subscription rights. No redemption or sinking fund provisions apply to the
common stock.

     All outstanding shares of common stock are fully paid and nonassessable.

     PREFERRED STOCK. As of August 11, 1999, no shares of preferred stock were
issued and outstanding. The board of directors has the authority to issue the
preferred stock in one or more series and to fix the following rights,
preferences, privileges and restrictions of the preferred stock without further
vote or action by our stockholders:

     - dividend rights and rates,

     - terms of conversion, voting rights, terms of redemption, liquidation
       preferences,

     - the number of shares constituting any series or the designation of such
       series.

Preferred stock could be issued quickly with terms calculated to delay or
prevent a change in control and may adversely affect the voting and other rights
of the holders of common stock. Except in accordance with the rights plan
described below, we have no present plans to issue any shares of preferred
stock.

     PREFERRED SHARES RIGHTS PLAN. On November 16, 1988, our board of directors
authorized a dividend distribution of one share purchase right for each share of
common stock outstanding as of the close of business on December 15, 1988 and
each future share of common stock. The Amended and Restated Preferred Shares
Rights Agreement dated November 20, 1998 between us and BankBoston, N.A., as
rights agent, provides, among other things, that after a distribution date, each
right entitles the registered holder to purchase from us 1/1000 of a share of
our Series A participating preferred stock, $0.01 par value, initially at a
price of $100.00.

     The rights will expire ten years after the date of issuance, or December
15, 2008, unless earlier redeemed, and will become exercisable and transferable
separately from the common stock following the tenth day after a person or
group:

     - acquires beneficial ownership of 20% or more of our common stock,

     - announces a tender or exchange offer, the consummation of which would
       result in ownership by a person or group of 30% or more of our common
       stock, or

                                       30
<PAGE>   31

     - a later date after the occurrence of an event described in clause (i) or
       (ii) above as may be determined by a majority of directors not affiliated
       with the acquiring group or person.

     If (a) an acquiror obtains 30% or more of our common stock, (b) an
acquiring entity combines with us in a transaction in which we are the surviving
company and our common stock remains outstanding and unchanged or (c) we effect
or permit certain "self-dealing" transactions with an owner of 20% or more of
our common stock or its affiliates or associates, then each right will entitle
the holder to purchase, at the then-current purchase price, a number of shares
of common stock having a then-current market value of twice the purchase price.

     If (x) we merge into another entity, (y) an acquiring entity merges into us
and our common stock is changed into or exchanged for other securities or assets
or (z) we sell more than 50% of our assets or earning power, then each right
will entitle the holder to purchase, at the then-current purchase price, a
number of shares of common stock of the person engaging in the transaction
having a then-current market value of twice the purchase price.

     We may redeem the rights at our option for $0.01 per right at any time on
or prior to the tenth day after public announcement that a person or group has
acquired beneficial ownership of 20% or more of our common stock or such later
date as may be determined by a majority of the directors not affiliated with the
acquiring group or person. The rights are also redeemable at our option
following the shares acquisition date if:

     - such redemption is in connection with a consolidation or merger in which
       we are not the surviving corporation,

     - no acquiror has held more than 20% of our common stock for less than the
       last three years, and

     - the redemption is approved by a majority of the directors not affiliated
       with the acquiring group or person.

Our right of redemption may be reinstated if the acquiring person or group
reduces its beneficial ownership to 10% or less of our common stock.


     The Series A participating preferred purchasable upon exercise of the
rights will be nonredeemable and junior to any other series of our preferred
stock. Each share of Series A participating preferred will have a preferential
cumulative quarterly dividend in an amount equal to 1,000 times the dividend
declared on each share of common stock. In the event of liquidation, the holders
of Series A participating preferred will receive a preferred liquidation payment
equal to 1,000 times the aggregate amount to be distributed per share to the
holders of shares of common stock plus accrued dividends. Following payment of
the Series A liquidation preference, and after the holders of shares of common
stock shall have received an amount per share equal to the quotient obtained by
dividing the Series A liquidation preference by 1,000, the holders of Series A
participating preferred and holders of common stock will share ratably and
proportionately the remaining assets to be distributed in liquidation. Each
share of Series A participating preferred will have 1,000 votes and will vote
together with the shares of common stock. In the event of any merger,
consolidation or other transaction in which shares of common stock are exchanged
for or changed into other securities, cash and/or other property, each share of
Series A


                                       31
<PAGE>   32

participating preferred will be entitled to receive 1,000 times the amount and
type of consideration received per share of common stock.

     Although the rights should not interfere with a business combination
approved by the board of directors in the manner set forth in the rights plan,
they may cause substantial dilution to a person or group that attempts to
acquire control without approval by the board.

DELAWARE GENERAL CORPORATION LAW SECTION 203

     We are a Delaware corporation subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203 prohibits
a publicly held Delaware corporation from engaging in a "business combination"
transaction with an "interested stockholder" for a period of three years after
the person became an interested stockholder, unless the business combination or
the transaction in which the person became an interested stockholder is approved
in the manner described below.

     The Section 203 restrictions do not apply if:

     (1) the business combination or transaction is approved by our board of
         directors before the date the interested stockholder obtained the
         status,

     (2) upon consummation of the transaction which resulted in the stockholder
         obtaining the status, the stockholder owned at least 85% of the shares
         of stock entitled to vote in the election of directors, the "voting
         stock". The 85% calculation does not include those shares:

        - owned by directors who are also officers of the target corporation,
          and

        - held by employee stock plans which do not permit employees to decide
          confidentially whether to accept a tender or exchange offer, or

     (3) on or after the date the interested stockholder obtained its status,
         the business combination is approved by our board of directors and at a
         stockholder meeting by the affirmative vote of at least 66 2/3% of the
         outstanding voting stock which is not owned by the interested
         stockholder.

     Generally, a "business combination" includes a merger, asset sale, or other
transaction resulting in a financial benefit to the interested stockholder.
Generally, an "interested stockholder" is a person who, together with affiliates
and associates, owns, or within three years prior to the determination of
interested stockholder status, did own, 15% or more of a corporation's voting
stock. Section 203 may prohibit or delay mergers or other takeover or change in
control attempts with respect to LSI Logic Corporation. As a result, Section 203
may discourage attempts to acquire us even though such transaction may offer our
stockholders the opportunity to sell their stock at a price above the prevailing
market price.

CHARTER AND BYLAW PROVISIONS

     Our charter and bylaws include provisions that may have the effect of
discouraging, delaying or preventing a change in control or an unsolicited
acquisition proposal that a stockholder might consider favorable, including a
proposal that might result in the payment of a premium over the market price for
the shares held by stockholders as follows:

     - our charter provides for cumulative voting at all elections of directors,

     - our board has the power to establish the rights, preferences and
       privileges of authorized and unissued shares,

     - our charter limits the liability of our directors, in their capacity as
       directors but not in their capacity as officers, to LSI Logic Corporation
       or its stockholders to the fullest extent permitted by Delaware law.

INDEMNIFICATION ARRANGEMENTS

     Our bylaws provide that our directors, officers and agents shall be
indemnified against expenses, including attorneys' fees, judgments, fines,
settlements actually and reasonably incurred in connection with any proceeding
arising out of their status as such, if such director, officer or agent acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of LSI Logic Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such conduct
was unlawful.

     We have entered into agreements to indemnify our directors and officers, in
addition to the indemnification provided for in our Certificate of Incorporation
and Bylaws. These agreements, among other things, indemnify our directors and
officers for certain expenses, including attorney's fees, judgments, fines and
settlement amounts incurred by any such person in any action or proceeding,
including any action by or in the right of LSI, arising out of such person's
services as a director or officer of LSI, any subsidiary of LSI or any other
company or enterprise to which the person provides services at the request of
LSI.

CHANGE OF CONTROL AGREEMENTS

     We have entered into certain severance agreements with each of our
executive officers providing for the acceleration of unvested options held by
such executive officers and the payment of certain lump sum amounts and benefits
upon an involuntary termination at any time within twelve (12) months after a
change of control.

     A "change of control" is defined as

     - the consummation of a merger or consolidation with any other corporation,
       other than a merger or consolidation in which we are the surviving
       entity,

     - the approval by our stockholders of a plan of liquidation or an agreement
       for the sale or disposition by us of all or substantially all of our
       assets, and

     - any person becoming the beneficial owner, as defined in Rule 13d-3 under
       the Securities and Exchange Act of 1934, as amended, of 50% or more of
       our total outstanding voting securities.

     Our successors shall be bound under the change of control severance
agreements. The change of control severance agreements terminate on November 20,
2003. Although these

                                       33
<PAGE>   34

should not interfere with a business combination, they may cause a substantial
dilution to a person or group that attempts to acquire us without approval of
our board of directors.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is Boston EquiServe,
L.P.

                              PLAN OF DISTRIBUTION

     We may sell the securities separately or together:

     - through one or more underwriters or dealers in a public offering and sale
       by them,

     - directly to investors, or

     - through agents.

     We may distribute the securities from time to time in one or more
transactions at a fixed price or prices. These prices may be changed from time
to time and may be set:

     - at market prices prevailing at the times of sale,

     - at prices related to such prevailing market prices, or

     - at negotiated prices.

     We will describe the method of distribution of the securities in the
prospectus supplement.

     Underwriters, dealers or agents may receive compensation in the form of
discounts, concessions or commissions from us or our purchasers (as their agents
in connection with the sale of securities). These underwriters, dealers or
agents may be considered to be underwriters under the Securities Act. As a
result, discounts, commissions, or profits on resale received by the
underwriters, dealers or agents may be treated as underwriting discounts and
commissions. The prospectus supplement will identify any such underwriter,
dealer or agent, and describe any compensation received by them from us. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.

     Underwriters, dealers and agents may be entitled to indemnification by us
against certain civil liabilities, including liabilities under the Securities
Act, or to contribution with respect to payments made by the underwriters,
dealers or agents, under agreements between us and the underwriters, dealers and
agents.

     We may grant underwriters who participate in the distribution of securities
an option to purchase additional securities to cover over-allotments, if any, in
connection with the distribution.

     All debt securities will be new issues of securities with no established
trading market. Underwriters involved in the public offering and sale of debt
securities may make a market in the debt securities. However, they are not
obligated to make a market and may discontinue market making activity at any
time. Therefore, we cannot give any assurances to you as to the liquidity of the
trading market for any debt securities.

                                       34

     Underwriters or agents and their associates may be customers of, engage in
transactions with or perform services for us in the ordinary course of business.

                                 LEGAL MATTERS

     The validity of the issuance of our securities offered by this prospectus
will be passed upon for LSI Logic Corporation by Wilson Sonsini Goodrich &
Rosati, Professional Corporation, Palo Alto, California.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS OF LSI

CERTIFICATE OF INCORPORATION

     Article 10 of our Certificate of Incorporation provides that, to the
fullest extent permitted by Delaware law, as the same now exists or may
hereafter be amended, a director shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. Delaware law provides that directors of a corporation will
not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability:

     - for any breach of their duty of loyalty to the corporation or its
       stockholders,

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law,

     - for unlawful payments of dividends or unlawful stock repurchases or
       redemptions as provided in Section 174 of the Delaware General
       Corporation Law, or

     - for any transaction from which the director derived an improper personal
       benefit.

BYLAWS

INDEMNIFICATION ARRANGEMENTS

     Our bylaws provide that our directors, officers and agents shall be
indemnified against expenses including attorneys' fees, judgments, fines,
settlements actually and reasonably incurred in connection with any proceeding
arising out of their status as such, if such director, officer or agent acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of LSI Logic Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such conduct
was unlawful.

     We have entered into agreements to indemnify our directors and officers, in
addition to the indemnification provided for in our Certificate of Incorporation
and Bylaws. These agreements, among other things, indemnify our directors and
officers for certain expenses, including attorney's fees, judgments, fines and
settlement amounts incurred by any such

ITEM 17. UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (a) To include any prospectus required by Section 10(a)(3) of the
     Securities Act,

          (b) 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

                                      II-2
<PAGE>   38

     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 percent change in
     the maximum aggregate offering price set forth in the "Calculation of
     Registration Fee" table in the effective registration statement,

          (c) 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;

provided, however, that clauses (a) and (b) do not apply if the information
required to be included in a post-effective amendment by such clauses is
contained in periodic reports filed with or furnished to the Securities and
Exchange Commission by the Registrant pursuant to Section 13 or Section 15(d) of
the Securities Exchange Act of 1934 (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 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 this 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 provisions described under Item 15 above, 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.

     The undersigned Registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act of
         1933, the information omitted from the form of prospectus filed as part
         of this registration statement in reliance upon Rule 430A and contained
         in a form of prospectus filed by the registrant pursuant to Rule
         424(b)(1) or (4) or 497(h) under the

                                      II-3
<PAGE>   39

         Securities Act shall be deemed to be part of this registration
         statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities Act
         of 1933, each post-effective amendment that contains a form of
         prospectus 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.

     Pursuant to the requirements of the Securities Act, the Registrant

Indenture to provide for the issuance from time to time of its unsecured
debentures, notes or other evidences of indebtedness (herein called the
"Securities"), to be issued in one or more series as provided in this Indenture.

         All things necessary to make this Indenture a valid agreement of the
Company, in accordance with its terms, have been done.

                   NOW, THEREFORE, THIS INDENTURE WITNESSETH:

         For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed, for the
equal and proportionate benefit of all Holders of the Securities or of series
thereof appertaining, as follows:

                                   ARTICLE ONE

             DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

<PAGE>   9

similar import refer to this Indenture as a whole and not to any particular

in Section 104.

         "Affiliate" of any specified Person means any other Person directly or

foregoing definition, rent shall not include amounts required to be paid by the
lessee, whether or not designated as rent or additional rent, on account of or

net amount determined assuming termination upon the first date such lease may be
terminated (in which case the net amount shall also include the amount of the
penalty, but no rent shall be considered as required to be paid under such lease
subsequent to the first date upon which it may be so terminated) and the net
amount determined assuming no such termination.

if at any time there is more than one such Person, "Trustee" as used with
respect to the Securities of any series shall mean the Trustee with respect to
Securities of that series.

         "U.S. Government Obligation" has the meaning specified in Section 1304.

         "Vice President," when used with respect to the Company or the Trustee,
means any vice president, whether or not designated by a number or a word or
words added before or after the title "vice president."

SECTION 102. COMPLIANCE CERTIFICATES AND OPINIONS.

         Upon any application or request by the Company to the Trustee to take
any action under any provision of this Indenture, the Company shall furnish to
the Trustee such certificates and opinions as may be required under the Trust
Indenture Act. Each such certificate or opinion shall be given in the form of an
Officers' Certificate, if to be given by an officer of the Company, or an
Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.


                                       -8-

<PAGE>   16

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include,

         (1) a statement that each individual signing such certificate or
opinion has read such covenant or condition and the definitions herein relating
thereto;

         (2) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based;

         (3) a statement that, in the opinion of each such individual, he or she
has made such examination or investigation as is necessary to enable him or her
to express an informed opinion as to whether or not such covenant or condition
has been complied with; and

         (4) a statement as to whether, in the opinion of each such individual,
such condition or covenant has been complied with.

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is
based are erroneous. Any such certificate or opinion of counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104. ACTS OF HOLDERS; RECORD DATES.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent



                                       -9-

<PAGE>   17

duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
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
instrument or instruments and records delivered to the Trustee. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the "Act" of the Holders signing such instrument
or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive in favor of the Trustee and the Company,
if made in the manner provided in this Section.

         The fact and date of the execution by any Person of any such 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
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him or her the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, 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.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, vote, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice


                                      -10-

<PAGE>   18

of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,


                                      -11-

<PAGE>   19

         (1) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing (or by
facsimile transmission ((213) 362-7357), provided that oral confirmation of
receipt shall have been received) to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust Administration or

         (2) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the
Trustee by the Company, Attention: Chief Financial Officer.

SECTION 106. NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. 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 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.

         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 as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which 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
which 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.

SECTION 108. 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.

SECTION 109. SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

SECTION 110. SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 112. GOVERNING LAW.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF
LAWS PRINCIPLES THEREOF.

SECTION 113. LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert a Security at a particular conversion price shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) or, if applicable to a
particular series of Securities, conversion need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, at the Stated Maturity or on such last day for
conversion, as the case may be.

SECTION 114. INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

         No recourse for the payment of the principal of or premium, if any, or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in this Indenture or in any supplemental indenture or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, employee, agent, officer, or
director or subsidiary, as such, past, present or future, of the Company or of
any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of
law, or

the Person entitled thereto as such address shall appear in the Security
Register].

Securities of this series at the time 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

SECTION 302. DENOMINATIONS.

         The Securities of each series shall be issuable only in registered form

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its principal financial
officer, its President or one of its Vice Presidents, attested by its Treasurer,
its Assistant Treasurer, Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
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 of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, a copy of such Board Resolution, the Officers' Certificate setting
forth the terms of the series and an Opinion of Counsel, with such Opinion of
Counsel stating,

         (1) if the form of such Securities has been established by or pursuant
to Board Resolution as permitted by Section 201, that such form has been
established in conformity with the provisions of this Indenture;

         (2) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 301, that such terms have
been established in conformity with the provisions of this Indenture; and

         (3) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company enforceable in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.



                                      -26-

<PAGE>   34

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

         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, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

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

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

SECTION 305. REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

         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 in a Place of Payment 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 Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         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 entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) 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 its attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, 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 304, 906 or 1107 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

<PAGE>   36

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

         (1) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated 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.

         (2) 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 such Global Security or a nominee
thereof unless (A) such Depositary (i) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (ii)
has ceased to be a clearing agency registered under the Exchange Act, (B) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security or (C) there shall exist such circumstances, if any, in addition
to or in lieu of the foregoing as have been specified for this purpose as
contemplated by Section 301.

         (3) Subject to Clause (2) above, any exchange of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

         (4) 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 Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
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.

SECTION 306. MUTILATED, DESTROYED, LOST AND 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 the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of 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 the same series and 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 may,
instead of issuing a new Security, pay such Security.


                                      -29-

<PAGE>   37

         Upon the issuance of any new Security under this Section, 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 and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

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

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, 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 of any series 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 of such series (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 of such series
and the date of the proposed payment, 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. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which 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 shall promptly notify the Company of such Special Record Date and, 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
given to each Holder of Securities of such series in the manner set forth in
Section 106, not less than 10 days prior to such Special Record Date.



                                      -30-

<PAGE>   38

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 of such series (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).

         (2) The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such 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, 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.

         Subject to the provisions of Section 1402, in the case of any Security
(or any part thereof) which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date (other than any Security the
principal of (or premium, if any, on) which shall become due and payable,
whether at Stated Maturity or by declaration of acceleration or otherwise prior
to such Interest Payment Date), interest whose Stated Maturity is on such
Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion and such interest (whether or not punctually
paid or duly provided for) shall be paid to the Person in whose name that
Security (or any one or more Predecessor Securities) is registered at the close
of business on such Regular Record Date. Except as otherwise expressly provided
in the immediately preceding sentence or in Section 1402, in the case of any
Security (or any part thereof) which is converted, interest whose Stated
Maturity is after the date of conversion of such Security (or such part thereof)
shall not be payable.

SECTION 308. 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 and any premium
and (subject to Section 307) any 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 309. CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder



                                      -31-

<PAGE>   39

which the Company has not issued and sold, and all Securities so delivered shall
be promptly canceled by the Trustee. No Securities shall be authenticated in
lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be returned to the Company.

SECTION 310. COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311. CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

         (1) either

                  (A) all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 306 and
         (ii) Securities for whose payment money has theretofore been deposited
         in trust or segregated and held in trust by the Company and thereafter
         repaid to the Company or discharged from such trust, as provided in
         Section 1003) have been delivered to the Trustee for cancellation; or

<PAGE>   40

                  (B) all such Securities not theretofore delivered to the
         Trustee for cancellation

                           (i) have become due and payable, or

                           (ii) will become due and payable at their Stated
                  Maturity within one year, or

                           (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company, and the Company,

                  in the case of (i), (ii) or (iii) above, has deposited or
                  caused to be deposited with the Trustee as trust funds in
                  trust for the purpose money in an amount sufficient to pay and
                  discharge the entire indebtedness on such Securities not
                  theretofore delivered to the Trustee for cancellation, for
                  principal and any premium and interest 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.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Company to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402. APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

SECTION 501. EVENTS OF DEFAULT.

         "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

         (1) default in the payment of any interest upon any Security of that
series when it becomes due and payable, and continuance of such default for a
period of 30 days; or

         (2) default in the payment of the principal of or any premium on any
Security of that series at its Maturity; or

         (3) default in the deposit of any sinking fund payment, when and as due
by the terms of a Security of that series; or

         (4) default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture (other than a covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such
default or breach for a period of 90 days after there has 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 25% in principal amount of the
Outstanding Securities of that series 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; or

         (5) 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 bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization, arrangement, adjustment or composition of or in respect of the
Company under any applicable Federal or State law, or appointing a custodian,
receiver, liquidator, assignee, trustee, sequestrator or other similar official
of the Company or of any substantial 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 90 consecutive days; or

         (6) the commencement by the Company of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or
other similar law or of any other case or proceeding to be adjudicated a
bankrupt or insolvent, or the consent by it to the entry of 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 to the commencement



                                      -34-

<PAGE>   42

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 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; or

         (7) any other Event of Default provided with respect to Securities of
that series.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding 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
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(5)
or 501(6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series 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 provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, 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 of that series,

                  (B) the principal of (and premium, if any, on) any Securities
         of that series which have become due otherwise than by such declaration
         of acceleration and any interest thereon at the rate or rates
         prescribed therefor in such Securities,

                  (C) to the extent that payment of such interest is lawful,
         interest upon overdue interest at the rate or rates prescribed therefor
         in such Securities, and



                                      -35-

<PAGE>   43

                  (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 with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

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

         (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, 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If an Event of Default with respect to Securities of any series 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 of such series 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 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
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 to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of



                                      -36-

<PAGE>   44

such payments directly to the Holders, to pay to the Trustee any amount due 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 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder 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 in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505. 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,

ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,

continuing Event of Default with respect to the Securities of that series;


                                      -37-

<PAGE>   45

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series 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 of that series;

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 to 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 of such
Holders.

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST AND TO CONVERT.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert
such Securities in accordance with Article Fourteen and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder 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 shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510. 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 306, no right or remedy herein conferred upon or reserved to the Trustee

                                      -38-

<PAGE>   46

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 511. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Securities
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
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee (subject to the limitations
contained in this Indenture) or by the Holders, as the case may be.

SECTION 512. CONTROL BY HOLDERS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series 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, with respect to the
Securities of such series, provided that

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture and the Trustee shall not have determined that the action so
directed would be unjustly prejudicial to Holders of Securities of that series,
or any other series, not taking part in such direction, and

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

SECTION 513. WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

         (1) in the payment of the principal of or any premium or interest on
any Security of such series, or

         (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series 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 514. UNDERTAKING FOR COSTS.

         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, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, including legal fees and
expenses, and may assess costs against any such party litigant, in the manner
and to the extent provided in the Trust Indenture Act; provided that neither
this Section nor the Trust Indenture Act shall be deemed to authorize any court
to require such an undertaking or to make such an assessment in any suit
instituted by the Company or the Trustee or in any suit for the enforcement of
the right to convert any Security in accordance with Article Fourteen.

SECTION 515. WAIVER OF USURY, STAY 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 usury, stay 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 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.


                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, 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. 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 602. NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default known to it as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means


                                      -40-

<PAGE>   48

any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

         (1) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

         (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order, and any resolution
of the Board of Directors shall be sufficiently evidenced by a Board Resolution;

         (3) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (4) the Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

         (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 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
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

         (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
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;


                                      -41-

<PAGE>   49

         (8) the Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture; and

         (9) the Trustee shall not be deemed to have notice of any default or
Event of Default unless a responsible officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture.

SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 605. MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

         Subject to the limitations imposed by the Trust Indenture Act, nothing
in this Indenture shall prohibit the Trustee from becoming and acting as trustee
under other indentures under which other securities, or certificates of interest
of participation in other securities, of the Company are outstanding in the same
manner as if it were not Trustee hereunder.

SECTION 606. MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.



                                      -42-

<PAGE>   50

SECTION 607. COMPENSATION AND REIMBURSEMENT.

         The Company agrees

         (1) to pay to the Trustee from time to time such compensation as shall
be agreed in writing between the Company and the Trustee for all services
rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

         (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

         (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State Bankruptcy, insolvency or
other similar law.

SECTION 608. 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. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most



                                      -43-

<PAGE>   51

recent report of condition so published. If at any time the Trustee with respect
to the Securities of any series 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.

SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         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 611.

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition, at
the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         If at any time:

         (1) the Trustee shall fail to comply with Section 608 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

         (2) the Trustee shall cease to be eligible under Section 609 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

         (3) 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, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder 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 with respect to all
Securities and the appointment of a successor Trustee or Trustees.


                                      -44-

<PAGE>   52

         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, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
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 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, the
retiring Trustee may petition, or any Holder who has been a bona fide Holder of
a Security of such series 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 with respect to the Securities of such
series.

         The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed 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
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.

         In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee



                                      -45-

<PAGE>   53

is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall, upon payment
in full of all of its charges, duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

         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 referred to in the
first or second preceding paragraph, as the case may be.

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

SECTION 612. 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 the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and 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 613. 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).

SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated 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. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference 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
acceptable to 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, having (or if the Authenticating Agent is a member of a bank holding
company system, its bank holding company has) a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal
or State authority. If such Authenticating Agent 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 Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         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 all or substantially all 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, 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

SECTION 906. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Company covenants and agrees for the benefit of each series of

and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

surrendered for conversion and where notices and demands to or upon the Company

furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be

order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as, and to the extent, in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company upon the income, profits
or property of the Company, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim (i) whose amount, applicability or validity is being contested in good
faith by appropriate proceedings or (ii) if the failure to pay or discharge
would not have a material adverse effect on the assets, business, operations,
properties or condition (financial or otherwise) of the Company and its
subsidiaries, taken as a whole.

guarantee, any Secured Debt (as defined below) without in any such case
effectively providing concurrently with issuance, incurrence, creation,
assumption or guarantee of any such Secured Debt, or the grant of a mortgage

the Company shall so determine, any other indebtedness of or guarantee by the
Company or such Restricted Subsidiary ranking equally with the Securities) shall
be secured equally and ratably with (or, at the option of the Company, prior to)
such Secured Debt. The foregoing restriction with respect to Secured Debt,
however, will not apply to:

prior to the contemplation of such acquisitions;

         (2) mortgages on property, shares of stock or indebtedness or other
assets of any corporation existing at the time such corporation becomes a

include property previously leased by the Company and leasehold interests
thereon, provided that the lease terminates prior to or upon the acquisition);

         (3) mortgages on property, shares of stock or indebtedness existing at
the time of acquisition thereof by the Company or a Restricted Subsidiary or
mortgages thereon to secure the payment of all or any part of the purchase price

commencement of substantial commercial operation of such property for the
purpose of financing all or any part of the purchase price thereof, such
construction, or the making of such improvements;

         (4) mortgages to secure indebtedness owing to the Company or to a
Restricted Subsidiary:

         (5) mortgages existing at the date of this Indenture;

         (6) mortgages on property of a corporation existing at the time such
corporation is merged into or consolidated with the Company or a Subsidiary or
at the time of a sale, lease or other disposition of the properties of a
corporation as an entirety or substantially as an entirety to the Company or a
Restricted Subsidiary, provided that such mortgage was not incurred in
anticipation of such merger or consolidation or sale, lease or other
disposition;

         (7) mortgages in favor of the United States or any State, territory or
possession thereof (or the District of Columbia), or any department, agency,
instrumentality or political subdivision of the United States or any State,
territory or possession thereof (or the District of Columbia), to secure
partial, progress, advance or other payments pursuant to any contract or statute

the cost of constructing or improving the property subject to such mortgages;

         (8) mortgages created in connection with the acquisition of assets or a
project financed with, and created to secure, a Nonrecourse Obligation;

         (9) extensions, renewals, refinancings or replacements of any mortgage
referred to in the foregoing clauses (1), (2), (3), (4), (5), (6), (7) and (8)
provided, however, that any mortgages permitted by any of the foregoing clauses
(1), (2), (3), (4), (5), (6), (7) and (8) shall not extend to or cover any
property of the Company or such Restricted Subsidiary, as the case may be, other
than the property, if any, specified in such clauses and improvements thereto,
and provided further that any refinancing or replacement of any mortgages
permitted by the foregoing clauses (7) and (8) shall be of the type referred to
in such clauses (7) or (8), as the case may be.

         Notwithstanding the restrictions outlined in the preceding paragraph,
the Company or any Restricted Subsidiary will be permitted to issue, incur,
create, assume or guarantee debt secured by a mortgage which would otherwise be
subject to such restrictions, without equally and ratably securing the
Securities, provided that after giving effect thereto, the aggregate amount of
all debt so secured by mortgages (not including mortgages permitted under
clauses (1) through (9) above) does not exceed the greater of $300 million or
10% of the Consolidated Net Tangible Assets of the Company as most recently
determine on or prior to such date.

         For purposes of this Section 1008:

         (i) "Secured Debt" means any debt for borrowed money secured by a
mortgage upon any Principal Property of the Company or any Restricted Subsidiary
or upon any shares of stock or indebtedness (whether such Principal Property,
shares or indebtedness are now existing or owed or hereafter created or
acquired); and

         (ii) "mortgage" means a mortgage, security interest, pledge, lien,
charge or other encumbrance.

SECTION 1009. LIMITATIONS ON SALE AND LEASEBACK TRANSACTIONS.

         The Company will not, nor will it permit any Restricted Subsidiary to,
enter into any Sale and Lease-Back Transaction with respect to any Principal
Property, other than any such transaction involving a lease for a term of not
more than three years of any such transaction between the Company and a
Restricted Subsidiary or between Restricted Subsidiaries, unless: (1) the
Company or such Restricted Subsidiary would be entitled to incurs indebtedness
secured by a mortgage on the Principal Property involved in such transaction at
least equal in amount to the Attributable Debt with respect to such Sale and
Lease-Back Transaction, without equally and ratably securing the Securities,
pursuant to Section 1008; or (2) the Company shall apply an amount equal to the
greater of the net proceeds of such sale or the Attributable Debt with respect
to such Sale and Lease-Back Transaction within 180 days of such sale to either
(or a combination of) the retirement (other than mandatory retirement, mandatory



                                      -58-

prepayment or sinking fund payment or by a payment at maturity) of debt for
borrowed money of the Company or a Restricted Subsidiary that matures more than
12 months after the creation of such indebtedness or the purchase, construction
or development of other comparable property.

         Notwithstanding the restrictions outlined is the preceding paragraph,
the Company or any Restricted Subsidiary will be permitted to enter into Sale
and Lease-Back Transactions which would otherwise be subject to such
restrictions, without applying the net proceeds of such transactions in the
manner set forth in clause (b) above, provided that after giving effect thereto,
the aggregate amount of such sale and Lease-Back Transactions, together with the
aggregate amount of all debt secured by mortgages not permitted by clauses (1)
through (9) under Section 1008 above, does not exceed the greater of $300
million or 10% of Consolidated Net Tangible Assets of the Company as most
recently determined on or prior to such date.

SECTION 1010. WAIVER OF CERTAIN COVENANTS.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(19),
901(2), 901(7), 1006, 1007, 1008 or 1009 for the benefit of the Holders of such
series if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities of such series shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision 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 in respect of any such
term, provision or condition shall remain in full force and effect.

SECTION 1011. CALCULATION OF ORIGINAL ISSUE DISCOUNT.

         The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

SECTION 1101. APPLICABILITY OF ARTICLE.

Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of the Securities of any series (including any such redemption affecting
only a single Security), the Company shall, at least 35 days (or 45 days if less
than all the Securities of any series are to be redeemed) prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by lot, or in the Trustee's
discretion, on a pro-rata basis, provided that the unredeemed portion of the
principal amount of any Security shall be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for such Security.
If less than all the Securities of such series and of a specified tenor are to
be redeemed (unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in
accordance with the preceding sentence.

         If any 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 shall be treated
by the Trustee as Outstanding for the purpose of such selection.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

<PAGE>   68

         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 1104. NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
each Holder of Securities to be redeemed, at its address appearing in the
Security Register.

         All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

         (1) the Redemption Date,

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

         (3) if less than all the Outstanding Securities of any series
consisting of more than a single Security are to be redeemed, the identification
(and, in the case of partial redemption of any such Securities, the principal
amounts) of the particular Securities to be redeemed and, if less than all the
Outstanding Securities of any series consisting of a single Security are to be
redeemed, the principal amount of the particular Security to be redeemed,

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

         (5) the place or places where each such Security is to be surrendered
for payment of the Redemption Price,

         (6) if applicable, the conversion price, that the date on which the
right to convert the principal of the Securities or the portions thereof to be
redeemed will terminate will be the Business Day prior to the Redemption Date
and the place or places where such Securities may be surrendered for conversion,
and

         (7) that the redemption is for a sinking fund, if such is the case.

         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 request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

         On or prior to 10:00 a.m., New York time, on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money 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.

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

SECTION 1106. 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 and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (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 its attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, 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.

                                  SINKING FUNDS


SECTION 1201. APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of such Securities is herein referred to as an "optional sinking fund
payment." If provided for by the terms of any Securities, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 1202.
Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, and, if applicable, Article Fourteen, (3) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (4) this Article. Subject to
compliance with this Article, the Company may exercise its option (if any) to
have this Section applied to any Securities notwithstanding the prior exercise
of its option (if any) to have Section 1303 applied to such Securities.

SECTION 1303. COVENANT DEFEASANCE.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1009, inclusive, and any covenants provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such Securities and (2) the
occurrence of any event specified in Sections 501(4) (with respect to any of
Sections 1006 through 1009, inclusive, and any such covenants provided pursuant
to Section 301(19), 901(2) or 901(7)) shall be deemed not to be or result in an
Event of Default, in each case with respect to such Securities as provided in
this Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or



                                      -64-

<PAGE>   72

limitation set forth in any such specified Section (to the extent so specified
in the case of Section 501(4)), whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or by reason of any reference in
any such Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of Section
1302 or Section 1303 to any Securities or any series of Securities, as the case
may be:

         (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.

         (2) In the event of an election to have Section 1302 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this instrument, there has been a change in
the applicable Federal income tax law, in either case (A) or (B) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, Defeasance and discharge to be effected with respect to
such Securities and will



                                      -65-

<PAGE>   73

be subject to Federal income tax on the same amount, in the same manner and at
the same times as would be the case if such deposit, Defeasance and discharge
were not to occur.

         (3) In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

         (4) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

         (5) No event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 501(5) and (6), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

         (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest within the meaning of the Trust Indenture Act
(assuming all Securities are in default within the meaning of such Act).

         (7) Such Defeasance or Covenant Defeasance shall not result in a breach
or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

         (8) Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act unless such trust shall be registered
under such Act or exempt from registration thereunder.

         (9) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.

SECTION 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to


                                      -66-

<PAGE>   74

the payment, either directly or through any such Paying Agent (including the
Company acting as its own Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in respect
of principal and any premium and interest, but money so held in trust need not
be segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

SECTION 1306. REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

                                ARTICLE FOURTEEN

                      CONVERSION AND EXCHANGE OF SECURITIES

SECTION 1401. APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to the Securities of

SECTION 1402. EXERCISE OF CONVERSION AND EXCHANGE PRIVILEGE.

         In order to exercise a conversion or exchange privilege, the Holder of
a Security of a series with such a privilege shall surrender such Security to
the Company at the office or agency maintained for that purpose pursuant to
Section 1002, accompanied by a duly executed conversion or exchange notice to
the Company substantially in the form set forth in Section 206 stating that the
Holder elects to convert such Security or a specified portion thereof. Such
notice shall also state, if different from the name and address of such Holder,
the name or names (with address) in which the certificate or certificates for
shares of Common Stock which shall be issuable on such conversion or exchange
shall be issued. Securities surrendered for conversion or exchange shall (if so
required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee
duly executed by the registered Holder or its attorney duly authorized in
writing; and Securities so surrendered for conversion or exchange (in whole or
in part) 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
(excluding Securities or portions thereof called for redemption during the
period beginning at the close of business on a Regular Record Date and ending at
the opening of business on the first Business Day after the next succeeding
Interest Payment Date, or if such Interest Payment Date is not a Business Day,
the second such Business Day) shall also be accompanied by payment in 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 then being
converted or exchanged, and such interest shall be payable to such registered
Holder notwithstanding the conversion or exchange of such Security, subject to
the provisions of Section 307 relating to the payment of Defaulted Interest by
the Company. As promptly as practicable after the receipt of such notice and of
any payment required pursuant to a Board Resolution and, subject to Section 303,
set forth, or determined in the manner provided, in an Officers' Certificate, or
established in one or more indentures supplemental hereto setting forth the
terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the
Company shall issue and shall deliver, at the office or agency at which such
Security is surrendered, to such Holder or on its written order, a certificate
or certificates for the number of full shares of Common Stock issuable upon the
conversion or exchange of such Security (or specified portion thereof), in
accordance with the provisions of such Board Resolution, Officers' Certificate
or supplemental indenture, and cash as provided therein in respect of any
fractional share of such Common Stock otherwise issuable upon such conversion or
exchange. Such conversion or exchange shall be deemed to have been effected
immediately prior to the close of business on the date on which such notice and
such payment, if required, shall have been received in proper order for
conversion or exchange by the Company and such Security shall have been
surrendered as aforesaid (unless such Holder shall have so surrendered such
Security and shall have instructed the Company to effect the conversion or
exchange on a particular date following such surrender and such Holder shall be
entitled to convert or exchange such Security on such date, in which case such
conversion or exchange shall be deemed to be effected immediately prior to the
close of business on such date) and at such time the rights of the Holder of
such Security as such Security Holder shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
of the Company shall be issuable upon such conversion or exchange shall be
deemed to have become the Holder or Holders of record of the shares represented
thereby. Except as set forth above and subject to the final paragraph of Section
307, no payment or adjustment shall be made upon any conversion or



                                      -68-

<PAGE>   76

exchange on account of any interest accrued on the Securities (or any part
thereof) surrendered for conversion or exchange or on account of any dividends
on the Common Stock of the Company issued upon such conversion or exchange.

         In the case of any Security which is converted or exchanged in part
only, upon such conversion or exchange the Company shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security.

SECTION 1403. NO FRACTIONAL SHARES.

         No fractional share of Common Stock of the Company shall be issued upon
conversions or exchanges of Securities of any series. If more than one Security
shall be surrendered for conversion or exchange at one time by the same Holder,
the number of full shares which shall be issuable upon conversion or exchange
shall be computed on the basis of the aggregate principal amount of the
Securities (or specified portions thereof to the extent permitted hereby) so
surrendered. If, except for the provisions of this Section 1403, any Holder of a
Security or Securities would be entitled to a fractional share of Common Stock
of the Company upon the conversion or exchange of such Security or Securities,
or specified portions thereof, the Company shall pay to such Holder an amount in
cash equal to the current market value of such fractional share computed, (i) if
such Common Stock is listed or admitted to unlisted trading privileges on a
national securities exchange or market, on the basis of the last reported sale
price regular way on such exchange or market on the last trading day prior to
the date of conversion or exchange upon which such a sale shall have been
effected, or (ii) if such Common Stock is not at the time so listed or admitted
to unlisted trading privileges on a national securities exchange or market, on
the basis of the average of the bid and asked prices of such Common Stock in the
over-the-counter market, on the last trading day prior to the date of conversion
or exchange, as reported by the National Quotation Bureau, Incorporated or
similar organization if the National Quotation Bureau, Incorporated is no longer
reporting such information, or if not so available, the fair market price as
determined by the Board of Directors. For purposes of this Section, "trading
day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday other than
any day on which the Common Stock is not traded on the Nasdaq National Market,
or if the Common Stock is not traded on the Nasdaq National Market, on the
principal exchange or market on which the Common Stock is traded or quoted.

SECTION 1404. ADJUSTMENT OF CONVERSION AND EXCHANGE PRICE.

         The conversion or exchange price of Securities of any series that is
convertible or exchangeable into Common Stock of the Company shall be adjusted
for any stock dividends, stock splits, reclassifications, combinations or
similar transactions in accordance with the terms of the supplemental indenture
or Board Resolutions setting forth the terms of the Securities of such series.


                                      -69-

<PAGE>   77

         Whenever the conversion or exchange price is adjusted, the Company
shall compute the adjusted conversion or exchange price in accordance with terms
of the applicable Board Resolution or supplemental indenture and shall prepare
an Officers' Certificate setting forth the adjusted conversion or exchange price
and showing in reasonable detail the facts upon which such adjustment is based,
and such certificate shall forthwith be filed at each office or agency
maintained for the purpose of conversion or exchange of Securities pursuant to
Section 1002 and, if different, with the Trustee. The Company shall forthwith
cause a notice setting forth the adjusted conversion or exchange price to be
mailed, first class postage prepaid, to each Holder of Securities of such series
at its address appearing on the Security Register and to any conversion or
exchange agent other than the Trustee.

SECTION 1405. NOTICE OF CERTAIN CORPORATE ACTIONS.

         In case:

         (1) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable otherwise than in cash out of its retained earnings
(other than a dividend for which approval of any shareholders of the Company is
required) that would require an adjustment pursuant to Section 1404; or

         (2) the Company shall authorize the granting to all or substantially
all of the holders of its Common Stock of rights, options or warrants to
subscribe for or purchase any shares of capital stock of any class or of any
other rights (other than any such grant for which approval of any shareholders
of the Company is required); or

         (3) of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding shares of Common Stock, or
of any consolidation, merger or share exchange to which the Company is a party
and for which approval of any shareholders of the Company is required), or of
the sale of all or substantially all of the assets of the Company; or

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

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in Clause
(1) or (2) above) prior to the applicable record date hereinafter specified, a
notice stating (i) 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 (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, 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, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the
conversion or exchange agent, a copy of such notice shall also forthwith be
filed by the Company with the Trustee.



                                      -70-

<PAGE>   78

SECTION 1406. RESERVATION OF SHARES OF 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 or exchange of Securities, the full number
of shares of Common Stock of the Company then issuable upon the conversion or
exchange of all outstanding Securities of any series that has conversion or
exchange rights.

SECTION 1407. PAYMENT OF CERTAIN TAXES UPON CONVERSION AND EXCHANGE.

         Except as provided in the next sentence, the Company will pay any and
all taxes that may be payable in respect of the issue or delivery of shares of
its Common Stock on conversion or exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the issue and delivery of shares of its
Common Stock in a name other than that of the Holder of the Security or
Securities to be converted or exchanged, 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 has established, to the satisfaction of the
Company, that such tax has been paid.

SECTION 1408. NONASSESSABILITY.

         The Company covenants that all shares of its Common Stock which may be
issued upon conversion or exchange of Securities will upon issue in accordance
with the terms hereof be duly and validly issued and fully paid and
nonassessable.

SECTION 1409. 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 of a series then Outstanding that is convertible or exchangeable
into Common Stock of the Company shall have the right thereafter (which right
shall be the exclusive conversion or exchange right thereafter available to said
Holder), during the period such Security shall be convertible or exchangeable,
to convert or exchange 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
or exchanged 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 (a "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, cash and other property receivable



                                      -71-

<PAGE>   79

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 1409 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). 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 or in accordance with the terms of the supplemental indenture or
Board Resolutions setting forth the terms of such adjustments. The above
provisions of this Section 1409 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 of a series that is convertible or exchangeable into
Common Stock of the Company as provided in Section 106 promptly upon such
execution.

         Neither the Trustee nor any conversion or exchange agent, if any, 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 of a series convertible or exchangeable into Common Stock
of the Company upon the conversion or exchange 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 1410. DUTIES OF TRUSTEE REGARDING CONVERSION AND EXCHANGE.

         Neither the Trustee nor any conversion or exchange agent shall at any
time be under any duty or responsibility to any Holder of Securities of any
series that is convertible or exchangeable into Common Stock of the Company to
determine whether any facts exist which may require any adjustment of the
conversion or exchange price, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, whether
herein or in any supplemental indenture (or whether any provisions of any
supplemental indenture are correct), any resolutions of the Board of Directors
or written instrument executed by one or more officers of the Company provided
to be employed in making the same. Neither the Trustee nor any conversion or
exchange agent shall be accountable with respect to the validity or value (or
the kind or amount) of any shares of Common Stock of the Company, or of any
securities or property, which may at any time be issued or delivered upon the
conversion or exchange of any Securities and neither the Trustee nor any
conversion or exchange agent makes any representation with respect thereto.
Subject to the provisions of Section 601, neither the Trustee nor any conversion
or exchange agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of its Common Stock or stock certificates or
other securities or property upon the surrender of any Security for the purpose
of conversion or exchange or to comply with any of the covenants of the



                                      -72-

<PAGE>   80

Company contained in this Article Fourteen or in the applicable supplemental
indenture, resolutions of the Board of Directors or written instrument executed
by one or more duly authorized officers of the Company.

SECTION 1411. REPAYMENT OF CERTAIN FUNDS UPON CONVERSION AND EXCHANGE.

         Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article Twelve hereof and funds deposited pursuant to
Article Thirteen hereof) and which shall not be required for such purposes
because of the conversion or exchange of such Securities as provided in this
Article Fourteen shall after such conversion or exchange be repaid to the
Company by the Trustee upon the Company's written request.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

SECTION 104.      ACTS OF HOLDERS; RECORD DATES.

or other action provided or permitted by this Indenture to be given, made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are 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 instrument or
instruments and records delivered to the Trustee. Such instrument or instruments
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

         The fact and date of the execution by any Person of any such 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
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him or her the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, 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.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, vote, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a

                                      -10-

<PAGE>   19
record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph. If any record date is set pursuant
to this paragraph, the Holders of Outstanding Securities of the relevant series
on such record date, and no other Holders, shall be entitled to take the
relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Company, at its own
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities of the relevant series in the manner set forth in
Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change

                                      -11-

the Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Expiration Date shall be later than the 180th day after the
applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

SECTION 105.      NOTICES, ETC., TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing (or by
facsimile transmission ((212) 815-5915), provided that oral confirmation of
receipt shall have been received) to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust Administration, or

         (2) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the
Trustee by the Company, Attention: Chief Financial Officer.

SECTION 106.      NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. 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 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.

         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 as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111.      BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness and the Holders, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

convert a Security at a particular conversion price shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) or, if applicable to a
particular series of Securities, conversion need not be made at such Place of

with the same force and effect as if made on the Interest Payment Date or
Redemption Date, at the Stated Maturity or on such last day for conversion, as
the case may be.

adjustment is to be made on conversion for interest accrued hereon or for
dividends on shares of Common Stock issued on conversion. The Company is not
required to issue fractional shares upon any such conversion, but shall make
adjustment therefor in cash on the basis of the current market value of such

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 sale of substantially all of the assets of the Company, the

consolidation, merger or sale by a holder of the number of shares of Common
Stock into which this Security might have been converted immediately prior to
such consolidation, merger or sale (assuming such holder of Common Stock 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). In the event of
conversion of this Security in part only, a new Security or Securities for the
unconverted portion hereof shall be issued in the name of the Holder hereof upon

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 to appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes.

amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of more than 50% in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, 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 upon the registration

SECTION 303.      EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

        The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its principal financial
officer, its President or one of its Vice Presidents, attested by its Treasurer,
its Assistant Treasurer, its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

        Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
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 of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, a copy of such

                                      -26-

<PAGE>   35
Board Resolution, the Officers' Certificate setting forth the terms of the
series and an Opinion of Counsel, with such Opinion of Counsel stating,

        (1) if the form of such Securities has been established by or pursuant
to Board Resolution as permitted by Section 201, that such form has been
established in conformity with the provisions of this Indenture;

        (2) if the terms of such Securities have been established by or pursuant
to Board Resolution as permitted by Section 301, that such terms have been
established in conformity with the provisions of this Indenture; and

        (3) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company enforceable in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

        If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

        Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

        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, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304.      TEMPORARY SECURITIES.

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

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

SECTION 305.      REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

        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 in a Place of Payment 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 Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

        Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

        At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

        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 entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

                                      -28-

<PAGE>   37

        Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) 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 its attorney duly authorized in writing.

        No service charge shall be made for any registration of transfer or
exchange of Securities, 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 304, 906 or 1107 not involving any transfer.

        If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

        The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

        (1) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated 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.

        (2) 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 such Global Security or a nominee
thereof unless (A) such Depositary (i) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or (ii)
has ceased to be a clearing agency registered under the Exchange Act, (B) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security or (C) there shall exist such circumstances, if any, in addition
to or in lieu of the foregoing as have been specified for this purpose as
contemplated by Section 301.

        (3) Subject to Clause (2) above, any exchange of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

        (4) 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 Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
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.

SECTION 306.      MUTILATED, DESTROYED, LOST AND 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 the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

        If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of 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 the same series and 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 may,
instead of issuing a new Security, pay such Security.

        Upon the issuance of any new Security under this Section, 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 and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

        Every new Security of any series issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

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

SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

        Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, 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 of any series 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:

                                      -30-

<PAGE>   39

        (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series (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 of such series
and the date of the proposed payment, 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. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which 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 shall promptly notify the Company of such Special Record Date and, 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
given to each Holder of Securities of such series in the manner set forth in
Section 106, 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 of such series (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).

        (2) The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such 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, 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.

        Subject to the provisions of Section 1402, in the case of any Security
(or any part thereof) which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date (other than any Security the
principal of (or premium, if any, on) which shall become due and payable,
whether at Stated Maturity or by declaration of acceleration or otherwise prior
to such Interest Payment Date), interest whose Stated Maturity is on such
Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion and such interest (whether or not punctually
paid or duly provided for) shall be paid to the Person in whose name that
Security (or any one or more Predecessor Securities) is registered at the close
of business on such Regular Record Date. Except as otherwise expressly provided
in the immediately preceding sentence or in Section 1402, in the case of any
Security (or any part thereof) which is converted, interest whose Stated
Maturity is after the date of conversion of such Security (or such part thereof)
shall not be payable.

SECTION 308.      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 and any premium and
(subject to Section 307) any 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 309.      CANCELLATION.

        All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be returned to the Company.

SECTION 310.      COMPUTATION OF INTEREST.

        Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311.      CUSIP NUMBERS.

        The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

SECTION 401.      SATISFACTION AND DISCHARGE OF INDENTURE.

        This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

        (1)    either

               (A) all Securities theretofore authenticated and delivered (other
        than (i) Securities which have been destroyed, lost or stolen and which
        have been replaced or paid as provided in Section 306 and (ii)
        Securities for whose payment money has theretofore been deposited in
        trust or segregated and held in trust by the Company and thereafter
        repaid to the Company or discharged from such trust, as provided in
        Section 1003) have been delivered to the Trustee for cancellation; or

               (B) all such Securities not theretofore delivered to the Trustee
        for cancellation

                        (i)   have become due and payable, or

                       (ii) will become due and payable at their Stated Maturity
        within one year, or

                       (iii) are to be called for redemption within one year
        under arrangements satisfactory to the Trustee for the giving of notice
        of redemption by the Trustee in the name, and at the expense, of the
        Company,

        and the Company, in the case of (i), (ii) or (iii) above, has deposited
        or caused to be deposited with the Trustee as trust funds in trust for
        the purpose money in an amount sufficient to pay and discharge the
        entire indebtedness on such Securities not theretofore delivered to the
        Trustee for cancellation, for principal and any premium and interest 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

<PAGE>   42



        Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Company to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402.      APPLICATION OF TRUST MONEY.

        Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                  ARTICLE FIVE

any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
Fifteen or be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or

        (4) default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture (other than a covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such
default or breach for a period of 90 days after there has 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 25% in principal amount of the
Outstanding Securities of that series 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; or

                                      -34-

<PAGE>   43

        (5) failure by the Company to make any payment at maturity, including
any applicable grace period, in respect of indebtedness, which term as used
herein means obligations (other than the Securities of such series or
non-recourse obligations) of the Company for borrowed money or evidenced by
bonds, debentures, notes or other similar instruments ("Indebtedness") in an
amount in excess of $25,000,000 or the equivalent thereof in any other currency
or composite currency and such failure shall have continued for thirty (30) days
after written notice thereof shall have been given to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in principal
amount of the Outstanding Securities of that series 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; or

        (6) the commencement by the Company of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or
other similar law or of any other case or proceeding to be adjudicated a

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 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 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; or

        (7) any other Event of Default provided with respect to Securities of
that series.

SECTION 502.      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

        If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding 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
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(5)
or 501(6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable. Any
payments by the Company on the Securities following any such acceleration will
be subject to the subordination provisions of Article Fifteen to the extent
provided therein.


                                      -35-

<PAGE>   44

        At any time after such a declaration of acceleration with respect to
Securities of any series 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 provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, 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 of that series,

               (B) the principal of (and premium, if any, on) any Securities of
        that series which have become due otherwise than by such declaration of
        acceleration and any interest thereon at the rate or rates prescribed
        therefor in such Securities,

               (C) to the extent that payment of such interest is lawful,
        interest upon overdue interest at the rate or rates prescribed therefor
        in such Securities, 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 with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                  TRUSTEE.

        The Company covenants that if

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

        (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, 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.


                                      -36-

<PAGE>   45
        If an Event of Default with respect to Securities of any series 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 of such series 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 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

        In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims 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 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, to
pay to the Trustee any amount due 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 607.

        No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder 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 in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.      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 such
judgment has been recovered.

SECTION 506.      APPLICATION OF MONEY COLLECTED.

        Any money collected by the Trustee pursuant to this Article 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 or any premium
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:

                                      -37-

<PAGE>   46



        FIRST: To the payment of all amounts due the Trustee under Section 607;
and

        SECOND: Subject to Article Fifteen, to the payment of the amounts then
due and unpaid for principal of and any premium, if any, and 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 and any premium, if
any, and interest, respectively.

SECTION 507.      LIMITATION ON SUITS.

        No Holder of any Security of any series 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 with respect to the Securities of that series;

        (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series 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 of that series;

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 to 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 of such
Holders.

SECTION 508.      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
                  AND INTEREST AND TO CONVERT.

        Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert
such Securities in

                                      -38-

<PAGE>   47

accordance with Article Fourteen and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

        If the Trustee or any Holder 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 shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510.      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 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders 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 511.      DELAY OR OMISSION NOT WAIVER.

        No delay or omission of the Trustee or of any Holder of any Securities
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
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee (subject to the limitations
contained in this Indenture) or by the Holders, as the case may be.

SECTION 512.      CONTROL BY HOLDERS.

        The Holders of a majority in principal amount of the Outstanding
Securities of any series 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, with respect to the
Securities of such series, provided that

        (1) such direction shall not be in conflict with any rule of law or with
this Indenture and the Trustee shall not have determined that the action so
directed would be unjustly prejudicial to Holders of Securities of that series,
or any other series, not taking part in such direction; and

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

                                      -39-

<PAGE>   48

SECTION 513.      WAIVER OF PAST DEFAULTS.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

        (1) in the payment of the principal of or any premium or interest on any
Security of such series, or

        (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series 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 514.      UNDERTAKING FOR COSTS.

        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, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, including legal fees and
expenses, and may assess costs against any such party litigant, in the manner
and to the extent provided in the Trust Indenture Act; provided that neither
this Section nor the Trust Indenture Act shall be deemed to authorize any court
to require such an undertaking or to make such an assessment in any suit
instituted by the Company or in any suit for the enforcement of the right to
convert any Security in accordance with Article Fourteen.

SECTION 515.      WAIVER OF USURY, STAY 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 usury, stay 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 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.

                                   THE TRUSTEE

SECTION 601.      CERTAIN DUTIES AND RESPONSIBILITIES.

        The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, 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. 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 602.      NOTICE OF DEFAULTS.

        If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default known to it as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. 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 with
respect to Securities of such series.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

        Subject to the provisions of Section 601:

        (1) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

        (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order, and any resolution
of the Board of Directors shall be sufficiently evidenced by a Board Resolution;

        (3) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;


                                      -41-

<PAGE>   50

        (4) the Trustee may consult with counsel of its selection and the advice
of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

        (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 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
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

        (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
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

        (8) the Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture; and

        (9) the Trustee shall not be deemed to have notice of any default or
Event of Default unless a responsible officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture.


SECTION 604.      NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

        The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 605.      MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

        The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

        Subject to the limitations imposed by the Trust Indenture Act, nothing
in this Indenture shall prohibit the Trustee from becoming and acting as trustee
under other indentures under which other securities, or certificates of interest
of participation in other securities, of the Company are outstanding in the same
manner as if it were not Trustee hereunder.

SECTION 606.      MONEY HELD IN TRUST.

        Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

SECTION 607.      COMPENSATION AND REIMBURSEMENT.

        The Company agrees

        (1) to pay to the Trustee from time to time such compensation as shall
be agreed in writing between the Company and the Trustee for all services
rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

        (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

        (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder.

        When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State Bankruptcy, insolvency or
other similar law.

<PAGE>   52
SECTION 608.      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. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609.      CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

        There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person 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 with respect to the Securities of any
series 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.

SECTION 610.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

        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 611.

        The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

        The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition, at
the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.


                                      -44-

<PAGE>   53

        If at any time:

        (1) the Trustee shall fail to comply with Section 608 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

        (2) the Trustee shall cease to be eligible under Section 609 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

        (3) 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, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder 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 with respect to all
Securities and the appointment of a successor Trustee or Trustees.

        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, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
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 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, the
retiring Trustee may petition, any Holder who has been a bona fide Holder of a
Security of such series 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 with respect to the Securities of such
series.

        The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

        In case of the appointment hereunder of a successor Trustee with respect
to all Securities, every such successor Trustee so appointed 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 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.

        In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall, upon payment
of all of its charges, duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

        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 referred to in the
first or second preceding paragraph, as the case may be.

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

SECTION 612.      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 the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and 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 613.      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).

SECTION 614.      APPOINTMENT OF AUTHENTICATING AGENT.

        The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated 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. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference 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
acceptable to 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, having (or if the Authenticating Agent is a member of a bank holding
company system, its bank holding company has) a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal
or State authority. If such Authenticating Agent 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 Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

        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

                                      -47-

<PAGE>   56

which such Authenticating Agent shall be a party, or any corporation succeeding
to all or substantially all 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, 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, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. 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.

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

        If an appointment with respect to one or more series is made pursuant to
this Section 612, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:
        This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

a list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders of Securities of each series as of such Regular Record
Date, as the case may be, and

        (2) at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company of any such request, a list of similar

is furnished;

provided that no such list need be furnished by the Company to the Trustee so
long as the Trustee is acting as Security Registrar.

SECTION 702.      PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

        The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701, if any, and the names
and addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

        The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding
rights and privileges of the Trustee, shall be as provided by the Trust
Indenture Act.

        Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

SECTION 703.      REPORTS BY TRUSTEE.

        The Trustee shall transmit to Holders such reports concerning the

shall, within sixty days after each July 15 following the date of this Indenture
deliver to Holders a brief report, dated as of such July 15, which complies with
the provisions of such Section 313(a).

        A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company
will promptly notify the Trustee when any Securities are listed on any stock
exchange or of any delisting thereof.

SECTION 704.      REPORTS BY COMPANY.

        The Company shall file with the Trustee and the Commission, and transmit
to Holders, such information, documents and other reports, and such summaries
thereof, as may be required pursuant to the Trust Indenture Act at the times and
in the manner provided pursuant to the Trust Indenture Act; provided that any
such information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the
Trustee within 15 days after the same is so required to be filed with the
Commission.

        Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

        A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for

        It shall not be necessary for any Act of Holders under this Section to

SECTION 1001.          PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

        The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002.          MAINTENANCE OF OFFICE OR AGENCY.

        The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served.
The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

        The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 1003.          MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

        If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

        Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, on or prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by

                                      -55-

<PAGE>   64

the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

        The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

        The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

        Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

SECTION 1004.          STATEMENT BY OFFICERS AS TO DEFAULT.

        The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. The fiscal year of the Company ends on June 30;
and the Company will give the Trustee prompt written notice of any change of its
fiscal year.

        Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence.

SECTION 1006.          MAINTENANCE OF PROPERTIES.

        The Company will cause all properties used or useful in the conduct of
its business to be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as, and to the extent, in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

SECTION 1007.          PAYMENT OF TAXES AND OTHER CLAIMS.

        The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or upon the income,
profits or property of the Company, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or (ii) if the failure to pay
or discharge would not have a material adverse effect on the assets, business,
operations, properties or condition (financial or otherwise) of the Company and
its subsidiaries, taken as a whole.

SECTION 1008.          WAIVER OF CERTAIN COVENANTS.

        Except as otherwise specified as contemplated by Section 301 for
Securities of such series or in a supplemental indenture, the Company may, with
respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any covenant provided
pursuant to Section 301(19), 901(2), 901(7), 1006 or 1007 for the benefit of the
Holders of such series if before the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision 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 in
respect of any such term, provision or condition shall remain in full force and
effect.

SECTION 1009.          CALCULATION OF ORIGINAL ISSUE DISCOUNT.

        The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                            REDEMPTION OF SECURITIES

SECTION 1101.          APPLICABILITY OF ARTICLE.

        Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.          ELECTION TO REDEEM; NOTICE TO TRUSTEE.

        The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 35
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

SECTION 1103.          SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

        If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by lot, or in the Trustee's discretion, on
a pro-rata basis, provided that the unredeemed portion of the principal amount
of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all
the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

        If any 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 shall be treated
by the Trustee as Outstanding for the purpose of such selection.


                                      -58-

<PAGE>   67



        The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

        The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

        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 1104.          NOTICE OF REDEMPTION.

        Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
each Holder of Securities to be redeemed, at its address appearing in the
Security Register.

        All notices of redemption shall identify the Securities to be redeemed
(including CUSIP number(s)) and shall state:

        (1) the Redemption Date,

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

        (3) if less than all the Outstanding Securities of any series consisting
of more than a single Security are to be redeemed, the identification (and, in
the case of partial redemption of any such Securities, the principal amounts) of
the particular Securities to be redeemed and, if less than all the Outstanding
Securities of any series consisting of a single Security are to be redeemed, the
principal amount of the particular Security to be redeemed,

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

        (5) the place or places where each such Security is to be surrendered
for payment of the Redemption Price,

        (6) if applicable, the conversion price, that the date on which the
right to convert the principal of the Securities or the portions thereof to be
redeemed will terminate will be the Business Day prior to

                                      -59-

<PAGE>   68

the Redemption Date and the place or places where such Securities may be
surrendered for conversion, and

        (7) that the redemption is for a sinking fund, if such is the case.

        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 request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 1105.          DEPOSIT OF REDEMPTION PRICE.

        On or prior to 10:00 a.m., New York time, on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money 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.

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

SECTION 1106.          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 and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

        If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107.          SECURITIES REDEEMED IN PART.

        Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument

                                      -60-

of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or its attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and of like tenor, 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

                                  SINKING FUNDS

SECTION 1201.          APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

        The minimum amount of any sinking fund payment provided for by the terms
of any Securities is herein referred to as a "mandatory sinking fund payment,"
and any payment in excess of such minimum amount provided for by the terms of
such Securities is herein referred to as an "optional sinking fund payment." If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

SECTION 1202.          SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

        The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.          REDEMPTION OF SECURITIES FOR SINKING FUND.

        Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall

                                      -61-

<PAGE>   70

select the Securities to be redeemed upon such sinking fund payment date in the
manner specified in Section 1103 and cause notice of the redemption thereof to
be given in the name of and at the expense of the Company in the manner provided
in Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107.

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.          COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT
                       DEFEASANCE.

        The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302.          DEFEASANCE AND DISCHARGE.

        Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article Fifteen shall cease to be effective, with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Defeasance"). For this
purpose, such Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged
hereunder: (1) the rights of Holders of such Securities to receive, solely from
the trust fund described in Section 1304 and as more fully set forth in such
Section, payments in respect of the principal of and any premium and interest on
such Securities when payments are due, (2) the Company's obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, and, if
applicable, Article Fourteen, (3) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (4) this Article. Subject to compliance
with this Article, the Company may exercise its option (if any) to have this
Section applied to any Securities notwithstanding the prior exercise of its
option (if any) to have Section 1303 applied to such Securities.

SECTION 1303.          COVENANT DEFEASANCE.

        Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1007, inclusive, and any covenants provided pursuant to Section 301(19),

                                      -62-

<PAGE>   71

901(2) or 901(7) for the benefit of the Holders of such Securities and (2) the
occurrence of any event specified in Sections 501(4) (with respect to any of
Sections 1006 through 1007, inclusive, and any such covenants provided pursuant
to Section 301(19), 901(2) or 901(7)), shall be deemed not to be or result in an
Event of Default, and (3) the provisions of Article Fifteen shall cease to be
effective, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)) or Article Fifteen, whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or
Article or by reason of any reference in any such Section or Article to any
other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

SECTION 1304.          CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

        The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

        (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.

<PAGE>   72

        (2) In the event of an election to have Section 1302 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this instrument, there has been a change in
the applicable Federal income tax law, in either case (A) or (B) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, Defeasance and discharge to be effected with respect to
such Securities and will be subject to Federal income tax on the same amount, in
the same manner and at the same times as would be the case if such deposit,
Defeasance and discharge were not to occur.

        (3) In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

        (4) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

        (5) No event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 501(5) and (6), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

        (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest within the meaning of the Trust Indenture Act
(assuming all Securities are in default within the meaning of such Act).

        (7) Such Defeasance or Covenant Defeasance shall not result in a breach
or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

        (8) Such Defeasance or Covenant Defeasance shall not result in the trust
arising from such deposit constituting an investment company within the meaning
of the Investment Company Act unless such trust shall be registered under such
Act or exempt from registration thereunder.

        (9) At the time of such deposit, (A) no default in the payment of any
principal of or premium or interest on any Senior Indebtedness shall have
occurred and be continuing, (B) no event of default with respect to any Senior
Indebtedness shall have resulted in such Senior Indebtedness becoming, and
continuing to be, due and payable prior to the date on which it would otherwise
have become due and payable (unless payment of such Senior Indebtedness has been
made or duly provided for), and (C) no

                                      -64-

<PAGE>   73
other event of default with respect to any Senior Indebtedness shall have
occurred and be continuing permitting (after notice or lapse of time or both)
the holders of such Senior Indebtedness (or a trustee on behalf of such holders)
to declare such Senior Indebtedness due and payable prior to the date on which
it would otherwise have become due and payable.

        (10) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.

SECTION 1305.          DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE
                       HELD IN TRUST; MISCELLANEOUS PROVISIONS.

        Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law. Money and U.S. Government
Obligations so held in trust shall not be subject to the provisions of Article
Fifteen.

        The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

        Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

SECTION 1306.          REINSTATEMENT.

        If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article;

                                      -65-

<PAGE>   74

provided, however, that if the Company makes any payment of principal of or any
premium or interest on any such Security following such reinstatement of its
obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities to receive such payment from the money so held in
trust.

                                ARTICLE FOURTEEN

                      CONVERSION AND EXCHANGE OF SECURITIES

SECTION 1401.          APPLICABILITY OF ARTICLE.

        The provisions of this Article shall be applicable to the Securities of
any series which are convertible or exchangeable into shares of Common Stock of
the Company, and the issuance of such shares of Common Stock upon the conversion
of such Securities, except as otherwise specified as contemplated by Section 301
for the Securities of such series.

SECTION 1402.          EXERCISE OF CONVERSION AND EXCHANGE PRIVILEGE.

        In order to exercise a conversion or exchange privilege, the Holder of a
Security of a series with such a privilege shall surrender such Security to the
Company at the office or agency maintained for that purpose pursuant to Section
1002, accompanied by a duly executed conversion or exchange notice to the
Company substantially in the form set forth in Section 206 stating that the
Holder elects to convert or exchange such Security or a specified portion
thereof. Such notice shall also state, if different from the name and address of
such Holder, the name or names (with address) in which the certificate or
certificates for shares of Common Stock which shall be issuable on such
conversion or exchange shall be issued. Securities surrendered for conversion or
exchange shall (if so required by the Company or the Trustee) be duly endorsed
by or accompanied by instruments of transfer in forms satisfactory to the
Company and the Trustee duly executed by the registered Holder or its attorney
duly authorized in writing; and Securities so surrendered for conversion or
exchange (in whole or in part) 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 (excluding Securities or portions thereof called for
redemption during the period beginning at the close of business on a Regular
Record Date and ending at the opening of business on the first Business Day
after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day) shall also be
accompanied by payment in 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 then being converted or exchanged, and such interest shall be
payable to such registered Holder notwithstanding the conversion or exchange of
such Security, subject to the provisions of Section 307 relating to the payment
of Defaulted Interest by the Company. As promptly as practicable after the
receipt of such notice and of any payment required pursuant to a Board
Resolution and, subject to Section 303, set forth, or determined in the manner
provided, in an Officers' Certificate, or established in one or more indentures
supplemental hereto setting forth the terms of such series of Security, and the
surrender of such Security in accordance with such reasonable regulations as the
Company may prescribe, the Company shall issue and shall deliver, at the office
or agency at which such Security is surrendered, to such Holder or on its
written order, a certificate or certificates for the

                                      -66-

<PAGE>   75

number of full shares of Common Stock issuable upon the conversion or exchange
of such Security (or specified portion thereof), in accordance with the
provisions of such Board Resolution, Officers' Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of
such Common Stock otherwise issuable upon such conversion or exchange. Such
conversion or exchange shall be deemed to have been effected immediately prior
to the close of business on the date on which such notice and such payment, if
required, shall have been received in proper order for conversion or exchange by
the Company and such Security shall have been surrendered as aforesaid (unless
such Holder shall have so surrendered such Security and shall have instructed
the Company to effect the conversion or exchange on a particular date following
such surrender and such Holder shall be entitled to convert or exchange such
Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) and at
such time the rights of the Holder of such Security as such Security Holder
shall cease and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock of the Company shall be issuable upon
such conversion or exchange shall be deemed to have become the Holder or Holders
of record of the shares represented thereby. Except as set forth above and
subject to the final paragraph of Section 307, no payment or adjustment shall be
made upon any conversion or exchange on account of any interest accrued on the
Securities (or any part thereof) surrendered for conversion or exchange or on
account of any dividends on the Common Stock of the Company issued upon such
conversion or exchange.

        In the case of any Security which is converted or exchanged in part
only, upon such conversion or exchange the Company shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security.

SECTION 1403.          NO FRACTIONAL SHARES.

        No fractional share of Common Stock of the Company shall be issued upon
conversions or exchanges of Securities of any series. If more than one Security
shall be surrendered for conversion or exchange at one time by the same Holder,
the number of full shares which shall be issuable upon conversion or exchange
shall be computed on the basis of the aggregate principal amount of the
Securities (or specified portions thereof to the extent permitted hereby) so
surrendered. If, except for the provisions of this Section 1403, any Holder of a
Security or Securities would be entitled to a fractional share of Common Stock
of the Company upon the conversion or exchange of such Security or Securities,
or specified portions thereof, the Company shall pay to such Holder an amount in
cash equal to the current market value of such fractional share computed, (i) if
such Common Stock is listed or admitted to unlisted trading privileges on a
national securities exchange or market, on the basis of the last reported sale
price regular way on such exchange or market on the last trading day prior to
the date of conversion or exchange upon which such a sale shall have been
effected, or (ii) if such Common Stock is not at the time so listed or admitted
to unlisted trading privileges on a national securities exchange or market, on
the basis of the average of the bid and asked prices of such Common Stock in the
over-the-counter market, on the last trading day prior to the date of conversion
or exchange, as reported by the National Quotation Bureau, Incorporated or
similar organization if the National

                                      -67-

<PAGE>   76
Quotation Bureau, Incorporated is no longer reporting such information, or if
not so available, the fair market price as determined by the Board of Directors.
For purposes of this Section, "trading day" shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the Common Stock is
not traded on the Nasdaq National Market, or if the Common Stock is not traded
on the Nasdaq National Market, on the principal exchange or market on which the
Common Stock is traded or quoted.

SECTION 1404.          ADJUSTMENT OF CONVERSION AND EXCHANGE PRICE.

        The conversion price of Securities of any series that is convertible or
exchangeable into Common Stock of the Company shall be adjusted for any stock
dividends, stock splits, reclassifications, combinations or similar transactions
in accordance with the terms of the supplemental indenture or Board Resolutions
setting forth the terms of the Securities of such series.

        Whenever the conversion or exchange price is adjusted, the Company shall
compute the adjusted conversion or exchange price in accordance with terms of
the applicable Board Resolution or supplemental indenture and shall prepare an
Officers' Certificate setting forth the adjusted conversion or exchange price
and showing in reasonable detail the facts upon which such adjustment is based,
and such certificate shall forthwith be filed at each office or agency
maintained for the purpose of conversion or exchange of Securities pursuant to
Section 1002 and, if different, with the Trustee. The Company shall forthwith
cause a notice setting forth the adjusted conversion or exchange price to be
mailed, first class postage prepaid, to each Holder of Securities of such series
at its address appearing on the Security Register and to any conversion or
exchange agent other than the Trustee.

SECTION 1405.          NOTICE OF CERTAIN CORPORATE ACTIONS.

        In case:

        (1) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable otherwise than in cash out of its retained earnings
(other than a dividend for which approval of any shareholders of the Company is
required) that would require an adjustment pursuant to Section 1404; or

        (2) the Company shall authorize the granting to all or substantially all
of the holders of its Common Stock of rights, options or warrants to subscribe
for or purchase any shares of capital stock of any class or of any other rights
(other than any such grant for which approval of any shareholders of the Company
is required); or

        (3) of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding shares of Common Stock, or
of any consolidation, merger or share exchange to which the Company is a party
and for which approval of any shareholders of the Company is required), or of
the sale of all or substantially all of the assets of the Company; or

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

                                      -68-

<PAGE>   77

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in Clause
(1) or (2) above) prior to the applicable record date hereinafter specified, a
notice stating (i) 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 (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, 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, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the
conversion or exchange agent, a copy of such notice shall also forthwith be
filed by the Company with the Trustee.

SECTION 1406.          RESERVATION OF SHARES OF 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 or exchange of Securities, the full number
of shares of Common Stock of the Company then issuable upon the conversion or
exchange of all outstanding Securities of any series that has conversion or
exchange rights.

SECTION 1407.          PAYMENT OF CERTAIN TAXES UPON CONVERSION AND EXCHANGE.

        Except as provided in the next sentence, the Company will pay any and
all taxes that may be payable in respect of the issue or delivery of shares of
its Common Stock on conversion or exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the issue and delivery of shares of its
Common Stock in a name other than that of the Holder of the Security or
Securities to be converted or exchanged, 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 has established, to the satisfaction of the
Company, that such tax has been paid.

SECTION 1408.          NONASSESSABILITY.

        The Company covenants that all shares of its Common Stock which may be
issued upon conversion or exchange of Securities will upon issue in accordance
with the terms hereof be duly and validly issued and fully paid and
nonassessable.

SECTION 1409.          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

                                      -69-

<PAGE>   78

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
of a series then Outstanding that is convertible or exchangeable into Common
Stock of the Company shall have the right thereafter (which right shall be the
exclusive conversion right thereafter available to said Holder), during the
period such Security shall be convertible or exchangeable, to convert or
exchange 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 or exchanged
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 (a "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, 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 1409 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). 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 or in accordance with the terms of the supplemental indenture or
Board Resolutions setting forth the terms of such adjustments. The above
provisions of this Section 1409 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 of a series that is convertible or exchangeable into
Common Stock of the Company as provided in Section 106 promptly upon such
execution.

        Neither the Trustee nor any conversion or exchange agent, if any, 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 of a series convertible or exchangeable into Common Stock
of the Company upon the conversion or exchange 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 1410.          DUTIES OF TRUSTEE REGARDING CONVERSION AND EXCHANGE.

        Neither the Trustee nor any conversion agent shall at any time be under
any duty or responsibility to any Holder of Securities of any series that is
convertible or exchangeable into Common Stock of the

                                      -70-

<PAGE>   79

Company to determine whether any facts exist which may require any adjustment of
the conversion or exchange price, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, whether
herein or in any supplemental indenture (or whether any provisions of any
supplemental indenture are correct), any resolutions of the Board of Directors
or written instrument executed by one or more officers of the Company provided
to be employed in making the same. Neither the Trustee nor any conversion or
exchange agent shall be accountable with respect to the validity or value (or
the kind or amount) of any shares of Common Stock of the Company, or of any
securities or property, which may at any time be issued or delivered upon the
conversion or exchange of any Securities and neither the Trustee nor any
conversion or exchange agent makes any representation with respect thereto.
Subject to the provisions of Section 601, neither the Trustee nor any conversion
or exchange agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of its Common Stock or stock certificates or
other securities or property upon the surrender of any Security for the purpose
of conversion or to comply with any of the covenants of the Company contained in
this Article Fourteen or in the applicable supplemental indenture, resolutions
of the Board of Directors or written instrument executed by one or more duly
authorized officers of the Company.

SECTION 1411.          REPAYMENT OF CERTAIN FUNDS UPON CONVERSION AND EXCHANGE .

        Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article Twelve hereof and funds deposited pursuant to
Article Thirteen hereof) and which shall not be required for such purposes
because of the conversion or exchange of such Securities as provided in this
Article Fourteen shall after such conversion or exchange be repaid to the
Company by the Trustee upon the Company's written request.

                                 ARTICLE FIFTEEN

                           SUBORDINATION OF SECURITIES

SECTION 1501.          SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

        Except as otherwise provided in a supplemental indenture or pursuant to
Section 301, the Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that the indebtedness
represented by the Securities and the payment of the principal of (and premium,
if any) and interest on each and all of the Securities is hereby expressly
subordinate and junior, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of all Senior Indebtedness.

        (1) In the event of any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, whether
in bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshaling of the assets
and liabilities of the Company or otherwise, then the holders of all Senior
Indebtedness shall

                                      -71-

<PAGE>   80

first be entitled to receive payment of the full amount due thereon in cash or
other consideration satisfactory to the holders of Senior Indebtedness in
respect of principal (and premium, if any) and interest, or provision shall be
made for such amount in money or money's worth, before the Holders of any of the
Securities are entitled to receive any payment or distribution of any character,
whether in cash, securities or other property, on account of the principal of
(or premium, if any) or interest on the indebtedness evidenced by the
Securities.

        For purposes of this Article Fifteen, 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, the payment of which
is subordinated at least to the extent provided in this Article Fifteen with
respect to the Securities to the payment of all Senior Indebtedness which may at
the time be outstanding; provided that (i) the Senior Indebtedness is assumed by
the new corporation, if any, resulting from any reorganization or readjustment,
and (ii) the rights of the holders of Senior Indebtedness (other than leases
which are not assumed by the Company or the new corporation, as the case may be)
are not, without the consent of such holders, altered by such reorganization or
readjustment. 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 property as an entirety, or
substantially as an entirety, to another person upon the terms and conditions
provided for in Article Eight shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 1501(1) if such
other person shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article Eight.

        (2) In the event of any default in payment of the principal of or
premium, if any, or interest on, rent under, or any other payment obligation
under any Senior Indebtedness (a "Payment Default") beyond any applicable grace
period with respect thereto, then, unless and until all such payments due in
respect of such Senior Indebtedness have been paid in full in cash or other
consideration satisfactory to holders of Senior Indebtedness or such default
shall have been cured or waived or shall have ceased to exist, no payment shall
be made by the Company with respect to the principal of, premium, if any, or
interest on the Securities or to acquire any of the Securities.

        (3) In the event (i) any event of default, other than a Payment Default,
with respect to any Designated Senior Indebtedness shall have occurred and be
continuing permitting the holders of such Designated Senior Indebtedness (or a
trustee or other representative on behalf of the holders thereof) to declare
such Designated Senior Indebtedness due and payable prior to the date on which
it would otherwise have become due and payable, upon written notice thereof to
the Company and the Trustee by any holders of such Designated Senior
Indebtedness (or a trustee or other representative on behalf of the holders
thereof) (the "Default Notice"), unless and until such event of default shall
have been cured or waived or shall have ceased to exist and such acceleration
shall have been rescinded or annulled, or (ii) 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, directly or indirectly, with respect to
principal of, premium, if any, or interest on the Securities; provided, however,
that clause (i) of this paragraph shall not prevent the making of any such
payment by the Company with respect to the

                                      -72-

<PAGE>   81

Securities for more than 179 days after a Default Notice shall have been
received by the Trustee unless the Designated Senior Indebtedness in respect of
which such event of default exists has been declared due and payable in its
entirety in which case no such payment may be made until such acceleration has
been rescinded or annulled or such Designated Senior Indebtedness has been paid
in full. Notwithstanding the foregoing, no event of default which existed or was
continuing on the date of any Default Notice shall be made the basis for the
giving of a second Default Notice; provided, further, however, that no
subsequent Default Notice shall be effective for purposes of this Section
1501(3) unless and until at least 365 days shall have elapsed since the initial
effectiveness of the immediately prior Default Notice.

        (4) If the maturity of the Securities is accelerated, no payment may be
made on the Securities until all amounts due or to become due on Senior
Indebtedness has been paid in full in cash or other consideration satisfactory
to holders of Senior Indebtedness or until such acceleration has been cured or
waived.

        (5) In the event that, notwithstanding the foregoing provisions of
Sections 1501(1), (2), (3) and (4), any payment on account of principal of or
interest on the Securities shall be made by or on behalf of the Company and
received by the Trustee, by any Holder or by any Paying Agent (or, if the
Company is acting as its own Paying Agent, money for any such payment shall be
segregated and held in trust), at a time when such payment is not permitted by
any of such provisions, then, unless and until all Senior Indebtedness (or
Designated Senior Indebtedness, in the case of Section 1051(3)) is paid in full
in cash or other consideration satisfactory to the holders thereof, or such
payment is otherwise permitted to be made by the provisions of each of Sections
1501(1), 1501(2), 1501(3) and 1501(4) (subject, in each case, to the provisions
of Section 1507), such payment on account of principal of or interest on the
Securities shall be held in trust for the benefit of, and shall be immediately
paid over to, the holders of Senior Indebtedness (or Designated Senior
Indebtedness, in the case of Section 1501(3)) or their representative or
representatives or the trustee or trustees under any indenture under which any
instruments evidencing any of the Senior Indebtedness (or Designated Senior
Indebtedness, in the case of Section 1501(3)) may have been issued, as their
interests may appear.

        Regardless of anything to the contrary herein, nothing shall prevent (a)
any payment by the Company or the Trustee to Holders of amounts in connection
with a redemption of Securities if (i) notice of such redemption has been given
pursuant to Section 1102 prior to the receipt by the Trustee of written notice
as aforesaid, and (ii) such notice of redemption is given not earlier than 75
days before the Redemption Date, or (b) any payment by the Trustee to the
Holders of amounts deposited with it pursuant to Sections 1501 and 1502.

SECTION 1502.          SUBROGATION.

         Subject to the payment in full of all Senior Indebtedness to which the
indebtedness evidenced by the Securities is in the circumstances subordinated as
provided in Section 1501, the Holders of the Securities (together with the
holders of any other indebtedness of the Company which is subordinate in right
of payment to the payment in full of all Senior Indebtedness, which is not
subordinate in right of payment to the Securities

                                      -73-

<PAGE>   82

and which by its terms grants such right of subrogation to the holders thereof)
shall be subrogated to the rights of the holders of such Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable to such Senior Indebtedness until all amounts owing on the Securities
shall be paid in full, and, as between the Company, its creditors other than
holders of such Senior Indebtedness, and the Holders of the Securities, no such
payment or distribution made to the holders of Senior Indebtedness by virtue of
this Article which otherwise would have been made to the Holders of the
Securities shall be deemed to be a payment by the Company on account of such
Senior Indebtedness, it being understood that 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.

SECTION 1503.          OBLIGATION OF COMPANY UNCONDITIONAL.

        Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as between the Company, its
creditors other than the 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 is intended to or shall affect the relative
rights of the Holders of the Securities and creditors of the Company other than
the holders of Senior Indebtedness, nor shall anything herein or therein 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 in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

SECTION 1504.        MODIFICATION OF TERMS OF SENIOR INDEBTEDNESS.

        Any renewal or extension of the time of payment of any Senior
Indebtedness or the exercise by the holders of Senior Indebtedness of any of
their rights under any instrument creating or evidencing Senior Indebtedness,
including without limitation the waiver of default thereunder, may be made or
done all without notice to or assent from the Holders of the Securities or the
Trustee.

        No compromise, alteration, amendment, modification, extension, renewal
or other change of, or waiver, consent or other action in respect of, any
liability or obligation under or in respect of, or of any of the terms,
covenants or conditions of any indenture or other instrument under which any
Senior Indebtedness is outstanding or of such Senior Indebtedness, whether or
not such release is in accordance with the provisions of any applicable
document, shall in any way alter or affect any of the provisions of this Article
or of the Securities relating to the subordination thereof

SECTION 1505.           PAYMENTS ON SECURITIES PERMITTED.

        Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Securities, shall affect the obligation of the Company to make, or
prevent the Company from making, payments of the principal of, or premium, if
any, or interest on the Securities in accordance with the provisions hereof and
thereof, or shall prevent the Trustee or any Paying Agent from applying any
moneys deposited with

                                      -74-

<PAGE>   83

it hereunder to the payment of the principal of, or premium, if any, or interest
on the Securities, in each case except as otherwise provided in this Article.

SECTION 1506.          EFFECTUATION OF SUBORDINATION BY TRUSTEE.

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

        Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee and the Holders of the Securities shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction in
which any such dissolution, winding up, liquidation or reorganization proceeding
affecting the affairs of the Company is pending or upon a certificate of the
trustee in bankruptcy, receiver, assignee for the benefit of creditors,
liquidating trustee or agent or other Person making any payment or distribution,
delivered to the Trustee or to the Holders of the Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, and as to other facts pertinent to the right of such Persons under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment to such Persons pending judicial determination as to the right of such
Persons to receive such payment.

SECTION 1507.          KNOWLEDGE OF TRUSTEE.

        Notwithstanding the provisions of this Article or any other provisions
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any Senior Indebtedness, of any default in payment of principal,
premium (if any) or interest on any Senior Indebtedness, or of any facts which
would prohibit the making of any payment of moneys to or by the Trustee, or the
taking of any other action by the Trustee, unless and until a Responsible
Officer of the Trustee having responsibility for the administration of the trust
established by this Indenture shall have received written notice thereof from
the Company, any Holder of Securities, any Paying or Conversion Agent of the
Company or the holder or representative of any class of Senior Indebtedness,
and, prior to the receipt of any such written notice, the Trustee shall be
entitled in all respects to assume that no such default or facts exist;
provided, however, that unless on the third Business Day prior to the date upon
which by the terms hereof any such moneys may become payable for any purpose
(other than a payment under Article Eleven) the Trustee shall have received the
notice provided for in this Section 1507, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys and apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it on or after such date.

SECTION 1508.          TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.

        The Trustee shall be entitled to all the rights set forth in this
Article with respect to any Senior Indebtedness at the time 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.


                                      -75-

<PAGE>   84

        Nothing in this Article shall apply to claims of or payments to the
Trustee under or pursuant to Section 607.

        With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and the Trustee shall
not be liable to any holder of Senior Indebtedness if it shall pay over or
deliver to Holders, the Company or any other Person moneys or assets to which
any holder of Senior Indebtedness shall be entitled by virtue of this Article or
otherwise.

SECTION 1509.          RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT IMPAIRED.

         No right of any present or future holder of any Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Company or by any
noncompliance 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.

SECTION 1510.          CERTAIN CONVERSIONS NOT DEEMED PAYMENT.

        For the purposes of this Article Fifteen only, (1) the issuance and
delivery of junior securities upon conversion of Securities in accordance with
Article Fourteen shall not be deemed to constitute a payment or distribution on
account of the principal of, premium, if any, or interest on Securities or on
account of the purchase or other acquisition of Securities, and (2) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 1403), property or securities (other than junior securities)
upon conversion of a Security shall be deemed to constitute payment on account
of the principal of, premium, if any, or interest on such Security. For the
purposes of this Section 1510, the term "junior securities" means (a) shares of
any stock of any class of the Company or (b) securities of the Company that are
subordinated in right of payment to all Senior Indebtedness 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 Fifteen 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, the right, which is absolute and unconditional, of the holder
of any Security to convert such note in accordance with Article Fourteen.

        RE:    LSI LOGIC CORPORATION -- REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

        At your request, we have examined the Registration Statement on Form
S-3, including Amendment No. 1 thereto (the "Registration Statement"), filed by
LSI Logic Corporation, a Delaware corporation (the "Company"), with the
Securities and Exchange Commission in connection with the registration pursuant
to the Securities Act of 1933, as amended (the "Act"), of the Company's senior
and subordinated debt securities (the "Debt Securities") and shares of the
Company's Common Stock, $0.01 par value per share (the "Common Stock"), with an
aggregate offering price of up to $600,000,000 or the equivalent thereof. The
Debt Securities and the Common Stock are to be sold from time to time as set
forth in the Registration Statement, the Prospectus contained therein (the
"Prospectus") and the supplements to the Prospectus (the "Prospectus
Supplements"). The Debt Securities are to be issued pursuant to a Senior Debt
Securities Indenture and a Subordinated Debt Securities Indenture, which have
been filed as exhibits to the Registration Statement (the "Indentures") and are
to be entered into between the Company and State Street Bank and Trust Company
of California, N.A. (the "Trustee"). The Debt Securities and shares of Common
Stock are to be sold pursuant to an underwriting agreement (the "Underwriting
Agreement"), in substantially the form to be filed under a Current Report on
Form 8-K. The Debt Securities are to be issued in the forms set forth in the
Indentures filed as exhibits to the Registration Statement.

        We have examined instruments, documents and records which we deemed
relevant and necessary for the basis of our opinion hereinafter expressed. In
such examination, we have assumed (a) the authenticity of original documents and
the genuineness of all signatures, (b) the conformity to the originals of all
documents submitted to us as copies and (c) the truth, accuracy, and
completeness of the information, representations and warranties contained in the
records, documents, instruments and certificates we have reviewed.

        Based on such examination, we are of the opinion that:

        1. The issuance of the Debt Securities has been duly authorized by
appropriate corporate action. The Debt Securities, in the forms set forth in the
Indentures filed as exhibits to the Registration Statement, when duly completed,
executed, authenticated and delivered in accordance with the Indentures and sold
pursuant to an appropriate Underwriting Agreement and as described in the
Registration Statement, any amendment thereto, the Prospectus and any Prospectus
Supplement relating thereto, will be legal, valid and binding obligations of the
Company, entitled to the benefits of such Indentures.

        2. The issuance of the shares of Common Stock has been duly authorized
by appropriate corporate action . The shares of Common Stock, duly issued, sold
and delivered in accordance with an appropriate Underwriting Agreement and as
described in the Registration Statement, any amendment thereto, the Prospectus
and the Prospectus Supplement relating thereto, will be legally issued, fully
paid and nonassessable.

        Our opinion that any document is legal, valid and binding is qualified
as to:

                (a) limitations imposed by bankruptcy, insolvency,
reorganization, arrangement, fraudulent conveyance, moratorium or other laws
relating to or affecting the rights of creditors generally; and

                (b) general principles of equity, including without limitation
concepts of materiality, reasonableness, good faith and fair dealing, and the
possible unavailability of specific performance or injunctive relief, regardless
of whether such enforceability is considered in a proceeding in equity or at
law.

        We hereby consent to the filing of this opinion as an exhibit to the
above-referenced Registration Statement and to the use of our name wherever it
appears in the Registration Statement, the Prospectus, the Prospectus
Supplement, and in any amendment or supplement thereto. In giving such consent,
we do not believe that we are "experts" within the meaning of such term as used
in the Act or the rules and regulations of the Securities and Exchange
Commission issued thereunder with respect to any part of the Registration
Statement, including this opinion as an exhibit or otherwise.

                                      Sincerely,
