                                 OWENS CORNING
 
     We are a world leader in providing consumer and industrial customers with
building materials systems and composites systems. The building materials are
used in residential remodeling and repair, commercial improvement, new
residential and commercial construction, and other related markets. Composite
materials are used in end-use markets such as building construction, automotive,
telecommunications, marine, aerospace, energy, appliance, packaging and
electronics. In 1998, our Building Materials segment accounted for 78% of our
total sales, and our Composite Materials segment accounted for 22% of total
sales.
 
BUILDING MATERIALS
 
     Our Building Materials business segment sells a variety of building and
home improvement products in three major categories: (1) glass fiber, foam and
mineral wool insulation, (2) roofing materials, and (3) exterior products for
the home, such as vinyl and metal siding and accessories, vinyl windows and
patio doors, rainware (gutters and downspouts), cast stone building products and
housewrap. The Owens Corning name, our trademarked color PINK and licensed Pink
Panther(TM) icon and our FIBERGLAS(R) trademark enjoy strong brand recognition
with consumers in the building materials market.
 
COMPOSITE MATERIALS
 
     We are the world's leading producer of glass fiber materials used in
composites. Composites are fabricated material systems made up of two or more
components (e.g., plastic resin and glass fiber) used in various applications to
replace traditional materials, such as aluminum, wood and steel. The global
composites industry has expanded to include thousands of end-use applications.
The primary end-use markets that we serve are transportation, building
construction, electrical/ electronics, consumer recreational and infrastructure.
In the construction market, the major end-use application for glass fiber is
asphalt roofing shingles.
 
                                USE OF PROCEEDS
 
     The net proceeds from the sale of the notes, after payment of expenses
related to this offering and the underwriting discounts and commissions, are
expected to be approximately $247 million. We intend to use the net proceeds to
repay a portion of the outstanding borrowings under our revolving credit
agreement dated as of June 26, 1997, as amended. The credit agreement has a
maximum commitment of $1.8 billion and provides for varying terms and interest
rates. The weighted average interest rate under the credit agreement was 6.25%
at December 31, 1998.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
(All per share information is on a diluted basis)
 
RESULTS OF OPERATIONS
 
  Business Overview
 
     Our growth agenda has focused on increasing sales and earnings by: (1)
acquiring businesses with products that can be sold through existing or
complementary distribution channels, (2) achieving productivity improvements and
cost reductions in existing and acquired businesses and (3) entering new growth
markets. We are implementing two major initiatives, the System Thinking(TM)
strategy and Advantage 2000, to enhance sales growth and achieve productivity
improvements across all businesses. System Thinking for the Home(TM) leverages
our broad product offering and strong brand recognition to increase our share of
the building materials and home improvement markets. This systems approach
represents a shift from product-oriented selling to providing systems-driven
solutions that combine our insulation, roofing, exterior and acoustic systems,
to provide a high performance, cost-effective building "envelope" for the home.
In the Composite Materials business, we have partnered with the plastics
industry and, with our System Thinking philosophy, are taking a
solution-oriented, customer-focused approach toward the continuous development
of substitution opportunities for composite materials. In addition, we are
implementing Advantage 2000, a fully integrated business technology system
designed to reduce costs and improve business processes.
 
     We have grown our sales from nearly $3.4 billion in 1994 to $5.0 billion in
1998. Acquisitions have been a significant component of that growth. Since 1994,
we have completed 17 acquisitions for an aggregate purchase price of over $1.2
billion. Our acquisitions have broadened our lines of business to include
siding, accessories and other home exteriors and have diversified our materials
portfolio beyond fiber glass to include polymers such as vinyl and styrene, and
metal and stone. In 1997, we completed the two largest of these acquisitions by
acquiring Fibreboard Corporation ("Fibreboard") and AmeriMark Building Products,
Inc. ("AmeriMark"), making us the leader in the U.S. vinyl siding, siding
accessories and manufactured stone markets, as well as a large specialty
distributor in North America through our 180 distribution centers.
 
     Despite improvements in our strategic position in 1997, we experienced a
highly competitive pricing environment in several of our product markets that
negatively impacted financial results. In North America, our insulation pricing
decreased by approximately 10 percent over the course of 1997 and worldwide
composites pricing decreased by approximately 6 percent during 1997. Income from
operations for 1997 was adversely impacted by approximately $87 million as a
result of price declines in insulation products and approximately $64 million as
a result of price declines affecting composite materials. Offset by small price
increases in other businesses, the net unfavorable effect of price on 1997
income from operations was approximately $142 million.
 
     During 1998, the pricing environment applicable to several of our major
products, particularly residential insulation, began to improve. Over the course
of the year, we announced three separate price increases, totaling 27%,
applicable to residential insulation. Another 9% price increase applicable to
such products was announced effective January 1999. In early 1998, we also
announced price increases applicable to our commercial and industrial insulation
products as well as our residential roofing products and composites products. By
the end of 1998, most notably in the fourth quarter, our average price levels of
insulation products surpassed the year-end 1997 levels. Despite the successful
implementation of price increases during 1998, including the restoration of
residential insulation prices to their late 1996 levels, income from operations
during 1998 was adversely impacted by approximately $44 million, compared to
1997, due largely to the relatively low insulation pricing base in effect at the
beginning of 1998, the lag in fully realizing the
 
                                       S-6

1998 price increases as we honor the remainder of pre-existing pricing
contracts, and price declines attributable to vinyl siding products. We expect
the upward price trend established during 1998 to continue into 1999.
 
     As a result of the growth of our business and the significant pricing
pressure experienced in 1997, we implemented a strategic restructuring program
designed to improve profitability, augment previously announced profitability
initiatives, and improve operational efficiency. The specific objectives of this
strategic program are discussed in "-- Restructuring of Operations and Other
Actions" below.
 
YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
  Sales and Profitability
 
     Net sales for the year ended December 31, 1998 were $5.009 billion,
reflecting a 15% increase from the 1997 level of $4.373 billion. Net sales in
1996 were $3.832 billion. The year to year increases are primarily due to the
acquisitions of Fibreboard and AmeriMark which were completed in the second and
fourth quarters of 1997, respectively. Continued strength in U.S. residential
roofing markets resulted in increased volume and price during 1998. Volume
declines in North American and European residential insulation markets were
partially offset by volume increases in mechanical and other insulation markets.
Although average price levels for insulation products were lower in 1998 than
1997 when calculated on an annual basis, residential insulation price levels
were higher in the fourth quarter of 1998 compared to the fourth quarter of
1997, indicating the benefits of the price increases implemented throughout 1998
and the establishment of an upward price trend which is expected to continue
into 1999. This represents a reversal of the downward trend in insulation
pricing experienced during 1997 and 1996. In the vinyl siding market, volume
increases were largely offset by declines in pricing during 1998. Volume
increases in North American composites markets during 1998, particularly during
the fourth quarter, helped to offset price declines in European and Asian
markets during the year. On a consolidated basis, there was virtually no impact
of currency translation on sales in foreign currencies during 1998.
 
     Sales outside the U.S. represented 20% of total sales for the year ended
December 31, 1998, compared to 24% during 1997 and 25% during 1996. The decline
in non-U.S. sales as a percentage of total sales in 1998 compared to 1997 and
1996 is due to the 1997 acquisitions of Fibreboard and AmeriMark, which are
primarily U.S. operations, and volume declines in Europe during 1998. Gross
margin for the year ended December 31, 1998 was 21% of net sales, compared to
20% and 26% in 1997 and 1996, respectively. The decline in gross margin as a
percentage of sales in 1998 and 1997 compared to 1996 and prior years is largely
attributable to the lower-margin businesses of the 1997 acquisitions. Cost of
sales in 1998 includes a $65 million charge as part of the $243 million charge
for restructuring and other actions described below. Gross margin during 1998
reflects the benefits of price improvements, cost reductions resulting from our
strategic restructuring program, and continuing productivity improvements across
our businesses. Cost of sales in 1997 includes a $38 million charge as part of
the $143 million charge for restructuring and other actions described below.
 
     For the year ended December 31, 1998, we reported a net loss of $705
million, or $13.16 per share, compared to net income of $47 million, or $.88 per
share, for the year ended December 31, 1997, and a net loss of $284 million, or
$5.54 per share, for the year ended December 31, 1996. Included in the 1998 net
loss are a $1.415 billion pretax charge ($906 million after-tax) for asbestos
litigation claims, a $243 million pretax charge ($171 million after-tax) for
restructuring and other actions and a $359 million pretax gain ($217 million
after-tax) from the sale of certain businesses. Net income in 1998 also reflects
manufacturing and operating expense reductions of approximately $110 million on
a pretax basis, resulting from our strategic restructuring program. Cost of
borrowed funds during 1998 was $140 million, $29 million higher than the 1997
level, due to higher levels of average debt, offset partially by a reduction in
average interest rates during 1998. The
 
                                       S-7
<PAGE>   8
 
reduction in equity in net income of affiliates for the year ended December 31,
1998 reflects the first quarter 1998 sale of our 50% ownership interest in
Alpha/Owens-Corning, LLC. As part of our debt realignment strategy, we
repurchased, via a tender offer, certain debt securities during the third
quarter of 1998 and recorded an extraordinary loss of $39 million, or $.72 per
share, net of related income taxes of $25 million.
 
     Net income for the year ended December 31, 1997 was $47 million, or $.88
per share, and reflects the adverse impact of lower prices in insulation and
composites worldwide compared to 1996. Net income for 1997 also includes a
pretax charge of $143 million ($104 million after-tax) for restructuring and
other actions; an increase in cost of borrowed funds and minority interest
expense compared to 1996, due primarily to the financing of the Fibreboard and
AmeriMark acquisitions; a $15 million credit ($10 million after-tax) resulting
from the modification of certain employee benefits in the second quarter of
1997; and a $15 million after-tax charge for the cumulative effect of the change
in method of accounting for business process reengineering costs.
 
     The 1996 net loss of $284 million, or $5.54 per share, reflects a pretax
charge of $875 million ($542 million after-tax) for asbestos litigation claims;
pretax charges totaling $42 million ($27 million after-tax) including valuation
adjustments associated with prior divestitures, major product line productivity
initiatives and a contribution to the Owens Corning Foundation; a pretax charge
of $43 million ($26 million after-tax) for restructuring and other actions; a
$27 million reduction of tax reserves due to favorable legislation; and a pretax
gain of $37 million ($27 million after-tax) from the sale of our ownership
interest in our former Japanese affiliate, Asahi Fiber Glass Co. Ltd.
 
     Marketing and administrative expenses were $587 million during 1998,
compared to $544 million and $500 million in 1997 and 1996, respectively. The
increase in marketing and administrative expenses reflects the incremental costs
due to acquisitions, partially offset by the benefits of cost reductions
resulting from our strategic restructuring program.
 
  Restructuring of Operations and Other Actions
 
     During the first and third quarters of 1998, we recorded a total pretax
charge of $243 million for restructuring and other actions as part of our
strategic restructuring program to reduce overhead, enhance manufacturing
productivity, and close manufacturing facilities, which was announced in early
1998. This charge includes $117 million for restructuring and $126 million for
other actions in 1998, the majority of which represent asset impairments. On a
cumulative basis since the fourth quarter of 1997, we have recorded a total
pretax charge of $386 million for this program, of which $185 million represents
restructure costs and $201 million represents other actions.
 
     The $117 million restructuring charge in 1998 includes approximately $90
million for costs associated with the elimination of approximately 1,900
positions worldwide and $27 million for the divestiture of non-strategic
businesses and facilities, of which $3 million represents exit cost liabilities,
comprised primarily of lease commitments. The $27 million charge for
non-strategic businesses and facilities includes $12 million for the closure of
certain U.S. manufacturing facilities, $6 million for the closure of a pipe
manufacturing facility in China, and $9 million for other actions.
 
     The primary components of the $126 million charge for other actions in 1998
and their classification on our consolidated statement of income include: $30
million to write down to fair value certain manufacturing assets held for use in
China, due primarily to poor current and projected financial results, recorded
as cost of sales; $15 million to write down to net realizable value equipment
and inventory made obsolete by changes in our manufacturing and marketing
strategies, recorded as cost of sales; $17 million for the write-down of an
investment in and the write-off of a receivable from a joint venture in Korea to
reflect the current business outlook and the fair market value of the assets,
recorded as other operating expenses; $12 million for the write-down of goodwill
associated with the 1995 acquisition of Fiber-lite, determined to be
unrecoverable due to a change in market conditions and customer demand, recorded
as other operating expenses; and $9 million for the write-down of certain assets
in the U.S. to fair market value, recorded as cost of
                                       S-8
<PAGE>   9
 
sales. We plan to hold and use the investments but disposed of most of the
equipment in 1998. Also included in the $126 million charge for other actions
are $13 million for the write-off of certain receivables in the U.S. and Asia
determined to be uncollectable, recorded as cost of sales and other operating
expenses; and $30 million for other actions recorded as cost of sales, marketing
and administrative expenses, and other operating expenses.
 
     During the fourth quarter of 1997, we recorded a $143 million pretax charge
for restructuring and other actions as the first phase of the strategic
restructuring program. The $143 million pretax charge was comprised of a $68
million charge associated with the restructuring of our business segments and a
$75 million charge associated with asset impairments, including investments in
certain affiliates. The components of the restructure charge include $25 million
for personnel reductions, $41 million for the divestiture of non-strategic
businesses and facilities, including the 1998 closure of the Candiac, Quebec
manufacturing facility, and $2 million for other actions. The $25 million for
personnel reductions represents severance costs associated with the elimination
of nearly 550 positions worldwide.
 
     The primary components of the $75 million charge for other actions and
their classification on our consolidated statement of income include: $17
million for the write-off of certain assets and investments associated with
unconsolidated joint ventures in Spain and Argentina due primarily to poor
current and projected financial results and the expected loss of local partners,
recorded as other operating expenses; $12 million for the write-down of certain
investments in mainland China to reflect the current business outlook and the
fair market value of the investments, recorded as cost of sales; $24 million to
write down to net realizable value equipment and inventory made obsolete by
changes in our manufacturing and marketing strategies, recorded as cost of
sales; $8 million for a supplemental employee retirement plan approved by the
Board of Directors in December 1997, recorded as marketing and administrative
expenses; $5 million for the write-off of an insurance receivable that was
determined to be uncollectable after judicial rejection of our claim, recorded
as other operating expenses; and $9 million for several other actions recorded
as cost of sales, marketing and administrative expenses, and other operating
expenses. We plan to hold and use the investments but disposed of the equipment
in 1998.
 
     During the fourth quarter of 1996, we recorded a $43 million pretax charge
for restructuring and other actions which included the costs associated with a
work force realignment, a replacement of computer technology and asset
valuations and expenses related to exited businesses. The $43 million pretax
charge was comprised of a $38 million restructure charge and a $5 million charge
related to an exited business. The components of the restructure charge included
$20 million for personnel reductions, $8 million in computer technology and $10
million for asset valuations and exited businesses. The $20 million for
personnel reductions represented severance costs associated with the elimination
of nearly 400 positions worldwide.
 
     As indicated above, certain of the charges recorded during 1998, 1997 and
1996 represent valuation adjustments associated with asset impairments. We
continually evaluate whether events and circumstances have occurred that
indicate that the carrying amount of certain long-lived assets is recoverable.
When factors indicate that a long-lived asset should be evaluated for possible
impairment, we use an estimate of the expected undiscounted cash flows to be
generated by the asset to determine whether the carrying amount is recoverable
or if an impairment exists. When it is determined that an impairment exists, we
use the fair market value of the asset, usually measured by the discounted cash
flows to be generated by the asset, to determine the amount of the impairment to
be recorded in the financial statements.
 
     As a result of the strategic restructuring program, we realized a decrease
in manufacturing and operating expenses of approximately $110 million during
1998. Based upon expected economic conditions over the next few years, including
effects on matters such as labor, material and other costs, we expect additional
cost reductions of approximately $65 million in 1999, resulting in ongoing
pretax savings of approximately $175 million per year. The expected $175 million
in cost
 
                                       S-9
<PAGE>   10
 
reductions, the majority of which will be cash savings, is comprised of $150
million in reduced personnel costs, $14 million in reduced facility costs, and
$11 million of reductions in related program spending. We also expect additional
cost savings during 1999 resulting from improved logistics and materials
sourcing.
 
     We also implemented programs to gain synergies in our Exterior Systems
Business during 1998. As a result of these programs, which include closing
redundant facilities, integrating business systems, and improving purchasing
leverage, we reduced costs by approximately $32 million during 1998 and expect
to save an additional $20 million per year in 1999 and beyond, the majority of
which will be cash savings.
 
  Building Materials
 
     In the Building Materials segment, sales increased 22% in 1998 compared to
1997, reflecting the incremental sales from the AmeriMark and Fibreboard
acquisitions. Building Materials sales reflect the benefits of volume increases
in North American vinyl siding and residential roofing markets during 1998,
offset partially by volume declines in European residential insulation markets.
Price increases in North American residential roofing markets were more than
offset by insulation and vinyl siding prices, which were lower on average for
total year 1998 than 1997. Prices of residential insulation, particularly in the
U.S., however, benefitted from an upward trend during much of 1998 and resulted
in prices during the fourth quarter of 1998 that were above fourth quarter 1997
levels. The translation impact of sales denominated in foreign currencies was
slightly unfavorable during 1998. Income from operations was $311 million during
1998, up from $172 million in 1997. Income from operations in 1998 reflects
productivity improvements and cost reductions resulting from the strategic
restructuring program, as well as strong residential roofing volume and price.
 
     Our consolidated financial results include the results of operations of
Fibreboard and AmeriMark beginning with the third and fourth quarters of 1997,
respectively. To enhance comparability, certain information below is presented
on a pro forma basis and reflects the acquisitions of Fibreboard (excluding
Pabco and operations that were discontinued by Fibreboard prior to the
acquisition) and AmeriMark as though they had occurred at the beginning of the
periods presented. (The pro forma impact of all acquisitions during 1997 and
1996, other than Fibreboard and AmeriMark, was not material to our results of
operations for those years.) The pro forma results include certain adjustments,
primarily for depreciation and amortization, interest and other expenses
directly attributable to the acquisitions, and are not necessarily indicative of
the combined results that would have occurred had the acquisitions occurred at
the beginning of that period. These pro forma results do not reflect the
benefits from the consolidation of the exterior systems business discussed
above.

  Composite Materials
 
     In the Composite Materials segment, sales were down 6% for the year ended
December 31, 1998 compared to 1997, due largely to the disposition (discussed
below) of 51% of our yarns and specialty materials business (the "yarns
business") late in the third quarter of 1998. Adjusted for the impact of this
disposition, sales were flat for the year ended December 31, 1998. Volume
increases in North American markets in 1998, particularly during the fourth
quarter, were offset by price declines across European and Asian markets. The
translation impact of sales denominated in foreign currencies was slightly
favorable during 1998. Income from operations was $202 million in 1998, compared
to $165 million in 1997. Reflected in income from operations during 1998 are the
benefits of productivity improvements and cost reductions from our restructuring
program, offset partially by reduced prices during 1998 and the deconsolidation
of our yarns business.
 
     During the third quarter of 1998, we formed a joint venture for our yarns
business to which we contributed two manufacturing plants and certain
proprietary technology. On September 30, 1998, we completed the sale of 51% of
the joint venture to a U.S. subsidiary of Groupe Porcher Industries of
Badinieres, France for $340 million. We continue to have a 49% ownership
interest in the joint venture. Upon closing, we also received a distribution of
approximately $193 million from the joint venture. By retaining a 49% ownership
interest in the joint venture, we will continue to safeguard our proprietary
technology and participate in the yarns market.
 
     Our consolidated balance sheet as of December 31, 1998 reflects the third
quarter 1998 disposition of our yarns business. The results of operations of the
yarns business are reflected in our consolidated statement of income through the
period ending September 30, 1998. For the nine months ended September 30, 1998
and the years ended December 31, 1997 and 1996, the yarns business recorded
sales of approximately $205 million, $277 million, and $275 million,
respectively, and income from operations of approximately $57 million, $80
million and $80 million, respectively. Effective September 30, 1998, we account
for our ownership interest in the yarns joint venture under the equity method.
 
  Accounting Changes
 
     During the first quarter of 1998, we adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130").
Comprehensive income is defined as the change in equity of a business enterprise
during a period from transactions and other events and circumstances from
non-owner sources. Our comprehensive income includes net income, currency
translation adjustments, minimum pension liability adjustments, and deferred
gains and losses on certain hedging transactions.
 
     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at our fair value. SFAS
133 requires that changes in the derivative's fair value be recognized currently
in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement, and requires
that a company must formally document, designate, and assess the effectiveness
of transactions that receive hedge accounting.
 
     SFAS 133 is effective for fiscal years beginning after June 15, 1999, but
earlier adoption is allowed. We have not yet quantified the impact of adopting
SFAS 133 and have not determined the timing of or the method of adoption. We are
aware, however, that the adoption of SFAS 133 could increase volatility in
earnings and other comprehensive income.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS
 
     Cash flow from operations was $124 million for the year ended December 31,
1998, compared to $131 million for the year ended December 31, 1997. The slight
decrease in cash flow from operations in 1998 is largely attributable to a $205
million increase in payments for asbestos litigation claims, net of insurance
proceeds, during 1998 compared to 1997. Payments for asbestos litigation claims
were $455 million during 1998 and proceeds from insurance were $47 million,
compared to $300 million and $97 million, respectively, during 1997. The
increase in net payments results principally from the fact that in conjunction
with the National Settlement Program ("NSP") negotiations in the fourth quarter
of 1998, we were able to achieve settlements on favorable terms of certain
appeals and other pending claims earlier than anticipated. We anticipate $850
million of total payments for asbestos litigation claims during 1999 due to the
implementation of our NSP. We expect that $150 million of insurance proceeds
will be available to cover these costs. During 1998, we collected a federal
income tax refund of approximately $85 million, which favorably impacted cash
flow from operations during the year.
 
     Inventories at December 31, 1998 decreased $66 million, including $37
million for divestitures and non-cash write-offs during the third quarter of
1998, from the December 31, 1997 level of $503 million. Receivables at December
31, 1998 were $451 million, a 5% increase over the December 31, 1997 level, due
largely to a $40 million increase in sales in December 1998 compared to December
1997. Receivables at December 31, 1998 also reflect a $39 million reduction
attributable to the divestitures and non-cash write-offs during the third
quarter of 1998. The increase in accounts payable and accrued liabilities from
$814 million at December 31, 1997 to $942 million at December 31, 1998 favorably
contributed to cash flow from operations during 1998. On an aggregate basis,
receivables, inventory, and accounts payable and accrued liabilities at December
31, 1998, adjusted for the divestitures and non-cash write-offs during the third
quarter of 1998, reflect improved working capital management during 1998.
 
     At December 31, 1998, our net working capital was negative $354 million and
our current ratio was .81, compared to $121 million and 1.09, respectively, at
December 31, 1997. A $500 million increase in the current portion of the reserve
for asbestos litigation claims, due to the implementation of our National
Settlement Program, partially offset by the related income tax benefit,
contributed to the decrease in net working capital at December 31, 1998.
 
     Our total borrowings at December 31, 1998 were $1.626 billion, $112 million
lower than at year-end 1997. Proceeds from the sale of businesses during 1998
were used to reduce debt as well as repurchase our trust preferred hybrid
securities during the year.
 
     As of December 31, 1998, we had unused lines of credit of $1.307 billion
available under long-term bank credit facilities and an additional $124 million
under short-term facilities, compared to $884 million and $224 million,
respectively, at year-end 1997. The net increase in unused available lines of
credit reflects our reduced borrowings at December 31, 1998 compared to December
31, 1997, offset partially by an agreed $200 million reduction in the maximum
availability from our long-term credit facility during the first quarter of
1998. Letters of credit issued under the facility, most of which support appeals
from asbestos trials, also reduce the available credit. The impact of such
reduction is reflected in the unused lines of credit discussed above.
 
     During 1998, we implemented a debt realignment program intended to reduce
financing costs. This program, which extended the average length of term debt
from four years to ten years, included the issuance of a total of $950 million
in new debt securities, the repurchase of our $309 million of trust preferred
hybrid securities and the retirement of $361 million of higher-rate debt
securities. In connection with this early retirement of debt, we paid premiums
of approximately $62 million, incurred related non-cash costs of approximately
$2 million, and recorded an extraordinary loss of approximately $39 million, or
$.72 per share, net of related income taxes of $25 million.
 
                                      S-12
<PAGE>   13
 
     Capital spending for property, plant and equipment, excluding acquisitions,
was $253 million in 1998. We anticipate 1999 capital spending, exclusive of
acquisitions and investments in affiliates, will be approximately $225 million,
the majority of which is uncommitted. We expect that funding for these
expenditures will be from our operations and external sources as required.
 
  Asbestos Litigation
 
     Gross payments for asbestos litigation claims during 1998, including
payments for claims settled in prior years and excluding amounts payable in
future years, were $455 million. The 1998 expenditures include $92 million in
defense and other costs. Proceeds from insurance were $47 million resulting in a
net pretax cash outflow of $408 million ($245 million after-tax). The increase
in 1998 expenditures from 1997 expenditures of approximately $300 million is
principally attributable to payments in 1998 for claims resolved in prior years
and to the fact that, in conjunction with the National Settlement Program
negotiations in the fourth quarter of 1998, we were able to achieve additional
settlements on favorable terms of certain appeals and other pending claims
earlier than anticipated. On December 15, 1998, we announced a National
Settlement Program ("NSP") under which more than 176,000 asbestos claims against
us will be resolved. Average payments per claim under the NSP are expected to be
substantially lower than those experienced by us in recent years. Settlement
payments aggregating approximately $1.2 billion for cases pending against us
will be made over a period of up to five years, with most payments occurring in
1999 and 2000. Such payments will be made from our available cash and credit
resources. As a result of such payments, our gross payments for asbestos
litigation claims will increase in 1999 and 2000 over the levels experienced in
recent years. However, such payments are expected to be substantially lower than
historical levels in 2001 and subsequent years. Our total payments for asbestos
litigation claims in 1999, including defense costs, are expected to be
approximately $850 million, due principally to payments in conjunction with the
NSP. Proceeds from insurance of $150 million are expected to be available to
cover these costs resulting in a net pretax cash outflow of $700 million ($450
million after-tax). In addition to providing for the resolution of approximately
176,000 claims against us, the NSP establishes administrative processing
arrangements with participating law firms under which future asbestos claims
will be resolved without litigation, with future claimants to receive specified
amounts based on the type and severity of disease and other factors.
 
     Gross payments for asbestos litigation claims against Fibreboard during
1998 were approximately $129 million, all of which was paid directly by
Fibreboard's insurers or from an escrow account funded by its insurers to
claimants on Fibreboard's behalf. Fibreboard is a participant in the NSP and is
a party to most of the NSP Agreements. If the Global Settlement is overturned by
the United States Supreme Court, and the Insurance Settlement therefore becomes
effective, it is anticipated that over 100,000 asbestos litigation claims
pending against Fibreboard will be resolved under the NSP. Payments of such
claims will be made over the next five years with most payments occurring in
1999 and 2000. Such payments will be made from the approximately $2.0 billion in
funds available under the Insurance Settlement to resolve pending and future
Fibreboard claims.
 
     We expect funds generated from operations, together with funds available
under long and short term bank credit facilities, to be sufficient to satisfy
our debt service obligations under our existing and anticipated indebtedness,
our contingent liabilities for uninsured asbestos personal injury claims, as
well as our capital expenditure programs and growth agenda.
 
  Environmental Matters
 
     We have been deemed by the Environmental Protection Agency ("EPA") to be a
Potentially Responsible Party ("PRP") with respect to certain sites under the
Comprehensive Environmental Response, Compensation and Liability Act
("Superfund"). We have also been deemed a PRP under similar state or local laws.
In other instances, other PRPs have brought suits or claims against us as a PRP
for contribution under such federal, state or local laws. During 1998, we were
                                      S-13
<PAGE>   14
 
designated as a PRP in such federal, state, local or private proceedings for
nine additional sites. At December 31, 1998, a total of 37 such PRP designations
remained unresolved by us, some of which designations we believe to be
erroneous. We are also involved with environmental investigation or remediation
at a number of other sites at which we have not been designated a PRP.
 
     We have established a $30 million reserve for our Superfund (and similar
state, local and private action) contingent liabilities. Based upon information
presently available to us, and without regard to the application of insurance,
we believe that, considered in the aggregate, the additional costs associated
with such contingent liabilities, including any related litigation costs, will
not have a materially adverse effect on our results of operations, financial
condition or long-term liquidity.
 
     The 1990 Clean Air Act Amendments ("Clean Air Act") provide that the EPA
will issue regulations on a number of air pollutants over a period of years.
Until these regulations are developed, we cannot determine the extent to which
the Clean Air Act will affect us. We anticipate that our sources to be regulated
will include wool fiber glass, mineral wool, amino/phenolic resin, secondary
aluminum smelting, asphalt processing and roofing, and metal coil coating. The
EPA's currently announced schedule is to issue regulations covering wool fiber
glass, mineral wool, amino/phenolic resin, secondary aluminum smelting, and
asphalt processing and roofing in 1999, and metal coil coating in 2000, with
implementation as to existing sources up to three years thereafter. Based on
information now known to us, including the nature and limited number of
regulated materials we emit, we do not expect the Clean Air Act to have a
materially adverse effect on our results of operations, financial condition or
long-term liquidity.
 
  Year 2000 Readiness
 
This information should be considered a Year 2000 Readiness Disclosure.
 
  Background
 
     Some of our existing information technology ("IT") systems and control
systems containing embedded technology such as processors, controllers and
microchips ("Non-IT") were originally programmed using two digits rather than
four digits to define the applicable year. As a result, such systems, if not
remediated, may experience miscalculations or disruptions when processing
information containing dates that fall after December 31,1999 or other dates
that could cause computer malfunctions (the "Year 2000 Issue").
 
  Our State of Readiness
 
     In recognition of the significance of the Year 2000 Issue, we formed a
senior management team representing business units and business process
functions including information technology, sourcing, logistics and legal. This
team oversees our efforts to assess and resolve the Year 2000 Issue. In
addition, our individual organizational units have developed, and are
implementing, Year 2000 plans. These plans include assessment of all our IT and
Non-IT systems and an evaluation of the external environment to identify
significant exposure areas and to develop appropriate remediation or other risk
management approaches. We are also developing business continuity plans to
assure that all of our operations are prepared in the case of an unexpected
system or supplier failure.
 
  IT Systems
 
     We have been actively implementing new systems and technology on a
worldwide basis since 1995 as part of our Advantage 2000 program to improve
productivity and operational efficiency. One objective of this initiative is to
ensure all business transactions are supporting requirements to process data
accurately in the year 2000 and beyond. The scope of this program has been
continuously expanded to include each of the seventeen acquisitions made by us
during the past five years.
                                      S-14
<PAGE>   15
 
     To date, over 75% of our IT systems are both ready for the year 2000 and
are already in operation for daily business transaction processing. This has
been accomplished through the comprehensive implementation of enterprise
resource planning software across most of our business units. Our schedule is to
have updated or replaced all remaining IT systems by the end of second quarter
1999. Management expects that most of these remaining IT systems will be in full
operation by the end of second quarter 1999 and that all will be in full
operation by the end of the third quarter. All significant system changes are
currently progressing to achieve this schedule.
 
  Non-IT Systems
 
     We have completed an inventory and assessment of substantially all of the
Non-IT systems in our operating facilities. Those Non-IT systems that may fail
as a result of the Year 2000 Issue have been identified. Corrective actions such
as replacement, update or installation of vendor supplied upgrades are currently
being performed. Concurrent with this renovation process, we are now testing
Year 2000 corrections to ensure that Non-IT systems will function properly on
key dates in accordance with testing methodologies which management believes are
reasonable and reflective of practices employed by comparable companies. As with
the IT systems discussed above, we plan to have all of the identified technology
remediated and tested by the end of second quarter 1999. Most locations will
also be operating with these remediated systems within the same time frame; all
locations are expected to be using these systems for business operations by the
end of third quarter 1999.
 
  External Environment
 
     We are working with our suppliers and customers to assess their level of
Year 2000 readiness. This process includes both the receipt of confirmation
documents as well as selective on-site visits. Critical suppliers have been
identified, confirmations received, and now we are conducting visits, which are
expected to be completed in first quarter 1999. Based upon results of the
confirmations and visits, we expect to develop any required contingency plans by
the end of the second quarter. Such contingency plans will include, as
appropriate, using alternate suppliers that are Year 2000 ready.
 
  Estimated Costs
 
     The cumulative cost of systems replacement, remediation and update from
1995 through 1998 has been approximately $145 million, including technology,
design and development, and related training and deployment in business
locations. We currently estimate that our remaining costs to assess and resolve
the Year 2000 Issue including the replacement and remediation at all remaining
locations are in the range of $25 million to $30 million. These cost estimates
are based on currently available information, and may be subject to change.
 
  Risks
 
     If we, or our materially significant suppliers, do not make needed
modifications and upgrades of systems on a timely basis, we could experience
significant disruptions to one or more of our operations, financial loss, legal
liability and similar risks, any of which could have a material adverse effect
on our results of operations or financial position. We believe that the most
reasonably likely worst case scenario would be a short-term slowdown or
cessation of manufacturing operations at one or more of our facilities and a
short-term inability on our part to process orders and billings in a timely
manner, and to deliver product to customers. In view of our Year 2000 readiness
program, including contingency and continuity plans, we believe that significant
disruptions are unlikely and that any disruptions would be both short-term and
manageable.

                       RATIO OF EARNINGS TO FIXED CHARGES
 
     For purposes of the calculation of the ratio of earnings to fixed charges,
earnings represent net income before fixed charges, provision for taxes on
income, undistributed earnings of equity basis investments, extraordinary losses
from early retirement of debt and the cumulative effect of accounting changes.
Fixed charges include interest expense, the portion (one-third) of rental
expense deemed to be representative of interest, and preferred stock dividend
requirements of consolidated subsidiaries. Our earnings were insufficient to
cover fixed charges in 1998 by approximately $1.0 billion and in 1996 by
approximately $600 million.

                              ASBESTOS LITIGATION
 
     We are a co-defendant with other former manufacturers, distributors and
installers of products containing asbestos and with miners and suppliers of
asbestos fibers in personal injury litigation. The personal injury claimants
generally allege injuries to their health caused by inhalation of asbestos
fibers from our products. Most of the claimants seek punitive damages as well as
compensatory damages. Virtually all of the asbestos-related lawsuits against us
arise out of our manufacture, distribution, sale or installation of an
asbestos-containing calcium silicate, high temperature insulation product, the
manufacture of which was discontinued in 1972.
 
NATIONAL SETTLEMENT PROGRAM
 
     As of September 30, 1998, approximately 196,300 asbestos personal injury
claims were pending against us. On December 15, 1998, we announced a National
Settlement Program under which more than 176,000 asbestos claims against us and
more than 100,000 claims against Fibreboard will be resolved. The program also
establishes procedures and fixed payments for resolving future claims brought by
participating plaintiffs' law firms without litigation for at least 10 years.
Average payments per claim under the NSP are expected to be substantially lower
than those experienced by us in recent years.
 
     For a discussion of our asbestos liabilities, see note 22 to our
consolidated financial statements for the year ended December 31, 1998
incorporated by reference in the accompanying prospectus and "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity, Capital Resources and Other Related Matters -- Asbestos Litigation"
included in this prospectus supplement.
 
                            DESCRIPTION OF THE NOTES
 
     The following describes the terms of the notes offered under this
prospectus supplement and should be read together with the statements in the
accompanying prospectus under the caption "Description of Debt Securities".
 
     The notes will be issued as a series of Debt Securities under the Indenture
(the "Indenture") dated as of May 5, 1997 between Owens Corning and The Bank of
New York, as Trustee, which is more fully described in the accompanying
prospectus.
 
     We will issue the notes as unsecured obligations in an aggregate principal
amount of $250,000,000. The notes will mature on March 15, 2009.
 
     We will not be required to make any sinking fund payments on the notes.
 
                                      S-16
<PAGE>   17
 
BOOK ENTRY, DELIVERY AND FORM
 
     The notes will be issued in book-entry form, as global notes registered in
the name of the nominee of The Depository Trust Company ("DTC"), which will act
as a depository. Beneficial interests in the book-entry notes will be shown on,
and transfers of the notes will be made only through, records maintained by DTC
and its participants. The provisions under "Description of Debt
Securities -- Book Entry Securities" in the prospectus will apply to the notes.
 
PAYMENT OF PRINCIPAL AND INTEREST
 
     Interest will begin to accrue on the notes on March 19, 1999. The interest
rate on the notes will be 7% per annum. We will pay interest semiannually in
arrears on March 15 and September 15 to the persons in whose names the notes are
registered on the March 1 or September 1 preceding the respective interest
payment date. The first interest payment will be made on September 15, 1999.
 
     The principal of, premium, if any, and interest on the notes will be
payable at the office of the Trustee. In addition, transfers of the notes will
be registrable at the office of the Trustee, and the notes may be presented for
exchange at the same location. So long as the notes are represented by
book-entry securities, the interest payable on the notes will be paid to DTC.
DTC will then credit the accounts of its participants, who will then pay
beneficial owners in accordance with customary practices and procedures on each
of the applicable interest payment dates. If the notes are no longer represented
by book-entry securities, payment of interest may, at our option, be made by
check mailed to the address of the person entitled to the payment.
 
OPTIONAL REDEMPTION
 
     The notes will be redeemable, in whole or in part, at our option at any
time at a redemption price equal to the greater of:
 
        - 100% of the principal amount of the notes; or
 
        - the sum of the present values of the remaining scheduled payments of
          principal and interest on the notes (not including the portion of any
          payments of interest accrued as of the redemption date) discounted to
          the redemption date on a semiannual basis at the Adjusted Treasury
          Rate, plus .375%.
 
We will also pay the accrued and unpaid interest on the notes to the redemption
date.
 
     The "Adjusted Treasury Rate" is a yield based on the yields on U.S.
treasury securities with comparable maturities and principal amounts to that of
the notes being redeemed. We will calculate the Adjusted Treasury Rate by taking
the arithmetic mean of the yields on U.S. treasury securities published under
the heading "Week Ending" under the caption "Treasury Constant Maturities" in
statistical release H.15(519), published weekly by the Federal Reserve System,
with maturities corresponding to the remaining life to maturity of the notes. If
statistical release H.15(519) or a successor publication of the Federal Reserve
Board is not available, we will designate a reasonably comparable index for this
calculation.
 
     If statistical release H.15(519), or any successor or alternative index,
does not have any U.S. treasury securities with maturities corresponding exactly
to the notes to be redeemed, we will use the yields on the two U.S. treasury
securities with maturities most closely corresponding to the remaining life to
maturity of the notes. We will then interpolate or extrapolate, on a straight
line basis, the Adjusted Treasury Rate based on these two published yields.
 
     The Adjusted Treasury Rate is to be determined on the third business day
preceding any redemption date and the maturity of U.S. treasury securities will
be rounded to the nearest month to determine those with maturities most closely
corresponding to the notes. The redemption price is calculated assuming a
360-day year consisting of twelve 30-day months.
 
                                      S-17
<PAGE>   18
 
     We will mail notice of any redemption at least 30 days but not more than 60
days before the redemption date to each holder of Notes to be redeemed. Interest
on the redeemed Notes will cease to accrue on the redemption date unless we
default on payment of the redemption price.
 
DEFEASANCE
 
     In the prospectus, there is a section called "Description of Debt
Securities -- Defeasance of Offered Debt Securities or Certain Covenants in
Certain Circumstances" which describes the circumstances under which we may be
released from most obligations under the notes or from most covenants in the
Indenture. In order to be released from these obligations, among other things,
we must deposit with the Trustee money or U.S. government securities in an
amount, including interest, sufficient to pay the accrued and unpaid interest
and principal on the notes. The defeasance provisions of the Indenture apply to
the notes.

     Under the terms and subject to the conditions contained in an underwriting
agreement and a related pricing agreement, each dated March 16, 1999, we have
agreed to sell to the underwriters the following principal amounts of the notes:

</TABLE>
 
     The underwriting agreement provides that the underwriters are obligated to
purchase all of the notes if any are purchased. The underwriting agreement
provides that if an underwriter defaults the purchase commitment of the
non-defaulting underwriter may be increased or the offering of the notes may be
terminated.
 
     The underwriters propose to offer the notes initially at the public
offering price on the cover page of this prospectus supplement and to selling
group members at that price less a concession of 0.40% of the principal amount
per note. The underwriters and selling group members may allow a discount of
0.25% of such principal amount per note on sales to other broker-dealers. After
the initial public offering, the public offering price and concession and
discount to broker-dealers may be changed.
 
     We estimate that our out-of-pocket expenses for this offering will be
approximately $350,000.
 
     The notes are a new issue of securities with no established trading market.
One or more of the underwriters intends to make a secondary market for the
notes. However, they are not obligated to do so and may discontinue making a
secondary market for the notes at any time without notice. No assurance can be
given as to how liquid the trading market for the notes will be.
 
     We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or contribute to payments which the underwriters may be required
to make in respect thereof.
 
     Affiliates of Credit Suisse First Boston Corporation are lenders under our
credit agreement and in the past have provided us with commercial banking
services. In the past Credit Suisse First Boston Corporation and Goldman, Sachs
& Co. have provided us with investment banking services. Each has received
customary fees for these services.
 
     The underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act of 1934. Over-allotment involves syndicate
sales in excess of the offering size, which creates a syndicate short position.
Stabilizing transactions permit bids to purchase the underlying security so long
as the stabilizing bids do not exceed a specified maximum. Syndicate covering
transactions involve purchases of notes in the open market after the
distribution has been completed in order to cover syndicate short positions.
Penalty bids permit the underwriters to reclaim a selling concession from a
broker/dealer when the notes originally sold by such broker/dealer are purchased
in a syndicate covering transaction to cover syndicate short positions. Such
stabilizing transactions, syndicate covering transactions and penalty bids may
cause the price of the notes to be higher than it would otherwise be in the
absence of such transactions. These transactions, if commenced, may be
discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
     The distribution of the notes in Canada is being made only on a private
placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of notes are effected. Accordingly, any resale of the notes in Canada
must be made in accordance with applicable securities laws, which will vary
depending on the relevant jurisdiction, and which may require resales to be made
in accordance with available statutory exemptions or pursuant to a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the notes.
 
REPRESENTATIONS OF PURCHASERS
 
     Each purchaser of notes in Canada who receives a purchase confirmation will
be deemed to represent to us and the dealer from whom such purchase confirmation
is received that (1) such purchaser is entitled under applicable provincial
securities laws to purchase such notes without the benefit of a prospectus
qualified under such securities laws, (2) where required by law, that such
purchaser is purchasing as principal and not as agent, and (3) such purchaser
has reviewed the text above under "Resale Restrictions".
 
RIGHTS OF ACTION (ONTARIO PURCHASERS)
 
     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.
 
ENFORCEMENT OF LEGAL RIGHTS
 
     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.
 
NOTICE TO BRITISH COLUMBIA RESIDENTS
 
     A purchaser of notes to whom the Securities Act (British Columbia) applies
is advised that such purchaser is required to file with the British Columbia
Securities Commission a report within ten days of the sale of any notes acquired
by such purchaser pursuant to this offering. Such report must be in the form
attached to British Columbia Securities Commission Blanket Order BOR #95/17, a
copy of which may be obtained from us. Only one such report must be filed in
respect of notes acquired on the same date and under the same prospectus
exemption.
 
TAXATION AND ELIGIBILITY FOR INVESTMENT
 
     Canadian purchasers of notes should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the notes in
their particular circumstances and with respect to the eligibility of the notes
for investment by the purchaser under relevant Canadian legislation.
 
                             VALIDITY OF THE NOTES
 
     The validity of the notes offered hereby will be passed upon for Owens
Corning by Shearman & Sterling, New York, New York and for the Underwriters by
Sullivan & Cromwell, Los Angeles, California.

Owens Corning Capital II and Owens Corning Capital III will not be subject to
the reporting requirements of the Exchange Act. When they issue preferred
securities under this prospectus, we will seek an exemption from the reporting
requirements of the Exchange Act for the trusts and propose to include their
summary financial information in a footnote to our consolidated financial
statements.
 
We do not believe that separate financial statements for the trusts would be
valuable in this prospectus or in separate Exchange Act filings because:
 
        - all of the voting securities of the trusts will be owned by Owens
          Corning, a reporting company under the Exchange Act, and
 
        - the trusts are special purpose entities with no operating history or
          independent operations and they are not engaged, nor do they propose
          to engage in, any activity other than purchasing our junior
          subordinated debt securities and issuing preferred securities and
          common securities.

                                  THE COMPANY
 
Owens Corning, a global company incorporated in Delaware in 1938, serves
consumers and industrial customers with high-performance glass composites and
building materials systems. These products are used in industries such as home
improvement, new construction, transportation, marine, aerospace, energy,
appliance, packaging and electronics. Many of these products are marketed under
the trademark FIBERGLAS(R) and/or the color PINK Trademark. The Company operates
in two industry segments -- Building Materials and Composite Materials. Owens
Corning acquired Fibreboard Corporation and AmeriMark Building Products, Inc. in
1997, making Owens Corning the leader in the U.S. vinyl siding, siding
accessories and cast stone markets, as well as providing Owens Corning with a
large network of company-owned specialty distribution centers. The Company also
has affiliate companies in a number of countries.
 
The Company's principal executive offices are located at Owens Corning World
Headquarters, Toledo, Ohio 43659, and its telephone number is (419) 248-8000.
Unless the context indicates otherwise, references in this Prospectus to the
"Company" include Owens Corning and its consolidated subsidiaries.
 
                                  THE ISSUERS
 
Each Issuer is a statutory business trust formed under Delaware law pursuant to
(i) a declaration of trust executed by the Company, as sponsor of such Issuer,
and the Delaware Trustee (as defined herein) of such Issuer and (ii) the filing
of a certificate of trust with the Delaware Secretary of State. Each declaration
of trust will be amended and restated in its entirety (each, as so amended and
restated, a "Trust Agreement") substantially in the form filed as an exhibit to
the Registration Statement of which this Prospectus forms a part. Each Trust
Agreement will be qualified as an indenture under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"). Each Issuer exists for the
exclusive purposes of (i) issuing and selling its common securities and
preferred securities (the "Trust Securities"), (ii) using the proceeds from the
sale of such Trust Securities to acquire Corresponding Junior Subordinated
Debentures issued by the Company and (iii) engaging in only those other
activities necessary, convenient or incidental thereto. Accordingly, the
Corresponding Junior Subordinated Debentures will be the sole assets of each
Issuer, and payments under the Corresponding Junior Subordinated Debentures and
the related Expense Agreement will be the sole revenue of each Issuer.
 
All of the Common Securities of each Issuer will be owned by the Company. The
Common Securities of an Issuer will rank pari passu, and payments will be made
thereon pro rata, with the Preferred Securities of such Issuer, except that upon
the occurrence and continuance of an event of default under a Trust Agreement
resulting from a Debenture Event of Default (as defined herein), the rights of
the Company as holder of the Common Securities to payment in respect of
Distributions and payments upon liquidation, redemption or otherwise will be
subordinated to the rights of the holders of the Preferred Securities of such
Issuer. See "Description of Preferred Securities -- Subordination of Common
Securities". The Company will acquire Common Securities in an aggregate
liquidation amount equal to not less than 3% of the total capital of each
Issuer.
 
Unless otherwise specified in the applicable Prospectus Supplement, each Issuer
has a term of approximately 55 years, but may terminate earlier as provided in
the applicable Trust Agreement. Each Issuer's business and affairs are conducted
by its trustees, each appointed by the Company as holder of the Common
Securities: Wilmington Trust Company as the Property Trustee (the "Property
Trustee") and as the Delaware Trustee (the "Delaware Trustee"), and two
individual trustees (the "Administrative Trustees") who are employees or
officers of or affiliated with the Company (collectively, the "Issuer
Trustees"). Wilmington Trust Company, as Property Trustee, will act as sole
indenture trustee under each Trust Agreement for purposes of compliance with the
Trust Indenture Act. Wilmington Trust Company will also act as trustee under
each Guarantee and the Subordinated Indenture. See "Description of Guarantees"
and "Description of Junior Subordinated Debentures". The holder of the Common
Securities of an Issuer, or the holders of a majority
                                        3
<PAGE>   24
 
in liquidation preference of the Preferred Securities of such Issuer if a
Debenture Event of Default with respect to the related Corresponding Junior
Subordinated Debentures has occurred and is continuing, will be entitled to
appoint, remove or replace the Property Trustee and/or the Delaware Trustee of
such Issuer. In no event will the holders of the Preferred Securities have the
right to vote to appoint, remove or replace the Administrative Trustees; such
voting rights are vested exclusively in the holder of the Common Securities. The
duties and obligations of each Issuer Trustee are governed by the applicable
Trust Agreement. The Company will pay all fees and expenses related to each
Issuer and the offering of its Preferred Securities and will pay, directly or
indirectly, all ongoing costs, expenses and liabilities of each Issuer. The
principal executive office of each Issuer is located at Owens Corning World
Headquarters, Toledo, Ohio 43659, and the telephone number is (419) 248-8000.
 
                                USE OF PROCEEDS
 
Except as set forth in a Prospectus Supplement, the Company intends to use the
net proceeds from the sale of the Securities (including Corresponding Junior
Subordinated Debentures issued to the Issuers in connection with the investment
by the Issuers of all of the proceeds from the sale of Preferred Securities) for
general corporate purposes, including, without limitation, working capital,
capital expenditures, investments in or loans to subsidiaries, repurchases or
redemptions of the Company's outstanding debt securities or other reductions of
the Company's outstanding borrowings, possible future business acquisitions, the
satisfaction of other obligations or for such other purposes as may be specified
in the applicable Prospectus Supplement.

                                        6
<PAGE>   27
 
Junior Subordinated Debentures may be presented for exchange as provided above,
and may be presented for registration of transfer (with the form of transfer
endorsed thereon, or a satisfactory written instrument of transfer, duly
executed), at the office of the appropriate Securities Registrar or at the
office of any transfer agent designated by the Company for such purpose with
respect to any series of Junior Subordinated Debentures and referred to in the
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the Subordinated Indenture.
The Company will appoint the Debenture Trustee as Securities Registrar under the
Subordinated Indenture. If the applicable Prospectus Supplement refers to any
transfer agents (in addition to the Securities Registrar) initially designated
by the Company with respect to any series of Junior Subordinated Debentures, the
Company may at any time rescind the designation of any such transfer agent or
approve a change in the location through which any such transfer agent acts,
provided that the Company maintains a transfer agent in each Place of Payment
for such series. The Company may at any time designate additional transfer
agents with respect to any series of Junior Subordinated Debentures.
 
In the event of any redemption, neither the Company nor the Debenture Trustee
shall be required to (i) issue, register the transfer of or exchange Junior
Subordinated Debentures of any series during a period beginning at the opening
of business 15 days before the day of selection for redemption of Junior
Subordinated Debentures of that series and ending at the close of business on
the day of mailing of the relevant notice of redemption or (ii) transfer or
exchange any Junior Subordinated Debentures so selected for redemption, except,
in the case of any Junior Subordinated Debentures being redeemed in part, any
portion thereof not to be redeemed.
 
GLOBAL JUNIOR SUBORDINATED DEBENTURES
 
The Junior Subordinated Debentures of a series may be issued in whole or in part
in the form of one or more Global Junior Subordinated Debentures that will be
deposited with, or on behalf of, a depositary (the "Subordinated Depositary")
identified in the Prospectus Supplement relating to such series. Global Junior
Subordinated Debentures may be issued only in fully registered form and in
either temporary or permanent form. Unless and until it is exchanged in whole or
in part for the individual Junior Subordinated Debentures represented thereby, a
Global Junior Subordinated Debenture may not be transferred except as a whole by
the Subordinated Depositary for such Global Junior Subordinated Debenture to a
nominee of such Subordinated Depositary or by a nominee of such Subordinated
Depositary to such Subordinated Depositary or another nominee of such
Subordinated Depositary or by the Subordinated Depositary or any nominee to a
successor Subordinated Depositary or any nominee of such successor.
 
The specific terms of the depositary arrangement with respect to a series of
Junior Subordinated Debentures will be described in the Prospectus Supplement
relating to such series. The Company anticipates that the following provisions
will generally apply to depositary arrangements.
 
Upon the issuance of a Global Junior Subordinated Debenture, and the deposit of
such Global Junior Subordinated Debenture with or on behalf of the Subordinated
Depositary, the Subordinated Depositary for such Global Junior Subordinated
Debenture or its nominee will credit on its book-entry registration and transfer
system, the respective principal amounts of the individual Junior Subordinated
Debentures represented by such Global Junior Subordinated Debenture to the
accounts of persons that have accounts with such Subordinated Depositary
("Participants"). Such accounts shall be designated by the dealers, underwriters
or agents with respect to such Junior Subordinated Debentures or by the Company
if such Junior Subordinated Debentures are offered and sold directly by the
Company. Ownership of beneficial interests in a Global Junior Subordinated
Debenture will be limited to Participants or persons that may hold interests
through Participants. Ownership of beneficial interests in such Global Junior
Subordinated Debenture will be shown on, and the transfer of that ownership will
be effected only through, records maintained by the applicable Subordinated
Depositary or its nominee (with respect to interests of Participants) and the
records of Participants (with respect to interests of persons who hold through
Partici-
                                        7
<PAGE>   28
 
pants). The laws of some states require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such limits and
such laws may impair the ability to transfer beneficial interests in a Global
Junior Subordinated Debenture.
 
So long as the Subordinated Depositary for a Global Junior Subordinated
Debenture, or its nominee, is the registered owner of such Global Junior
Subordinated Debenture, such Subordinated Depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the Junior
Subordinated Debentures represented by such Global Junior Subordinated Debenture
for all purposes under the Subordinated Indenture. Except as provided below,
owners of beneficial interests in a Global Junior Subordinated Debenture will
not be entitled to have any of the individual Junior Subordinated Debentures of
the series represented by such Global Junior Subordinated Debenture registered
in their names, will not receive or be entitled to receive physical delivery of
any such Junior Subordinated Debentures of such series in definitive form and
will not be considered the owners or holders thereof under the Subordinated
Indenture.
 
Payments of principal of (and premium, if any) and interest on individual Junior
Subordinated Debentures represented by a Global Junior Subordinated Debenture
registered in the name of the Subordinated Depositary or its nominee will be
made to the Subordinated Depositary or its nominee, as the case may be, as the
registered owner of the Global Junior Subordinated Debenture representing such
Junior Subordinated Debentures. None of the Company, the Debenture Trustee, any
paying agent, or the Securities Registrar for such Junior Subordinated
Debentures will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interest
of the Global Junior Subordinated Debenture for such Junior Subordinated
Debentures or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
The Company expects that the Subordinated Depositary for a series of Junior
Subordinated Debentures or its nominee, upon receipt of any payment of
principal, premium or interest in respect of a permanent Global Junior
Subordinated Debenture representing any of such Junior Subordinated Debentures,
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the principal amount of
such Global Junior Subordinated Debenture for such Junior Subordinated
Debentures as shown on the records of such Subordinated Depositary or its
nominee. The Company also expects that payments by Participants to owners of
beneficial interests in such Global Junior Subordinated Debenture held through
such Participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of customers
in bearer form or registered in "street name". Such payments will be the
responsibility of such Participants.
 
Unless otherwise specified in the applicable Prospectus Supplement, if the
Subordinated Depositary for a series of Junior Subordinated Debentures is at any
time unwilling, unable or ineligible to continue as depositary and a successor
depositary is not appointed by the Company within 90 days, the Company will
issue individual Junior Subordinated Debentures of such series in exchange for
the Global Junior Subordinated Debenture representing such series of Junior
Subordinated Debentures. In addition, the Company may at any time and in its
sole discretion, subject to any limitations described in the Prospectus
Supplement relating to such Junior Subordinated Debentures, determine not to
have any Junior Subordinated Debentures of such series represented by one or
more Global Junior Subordinated Debentures and, in such event, will issue
individual Junior Subordinated Debentures of such series in exchange for such
Global Junior Subordinated Debentures. Further, if the Company so specifies with
respect to the Junior Subordinated Debentures of a series, an owner of a
beneficial interest in a Global Junior Subordinated Debenture representing
Junior Subordinated Debentures of such series may, on terms acceptable to the
Company, the Debenture Trustee and the Subordinated Depositary for such Global
Junior Subordinated Debenture, receive individual Junior Subordinated Debentures
of such series in exchange for such beneficial interests, subject to any
limitations described in the Prospectus Supplement relating to such Junior
Subordinated Debentures. In any such instance, an owner of a
                                        8
<PAGE>   29
 
beneficial interest in a Global Junior Subordinated Debenture will be entitled
to physical delivery of individual Junior Subordinated Debentures of the series
represented by such Global Junior Subordinated Debenture equal in principal
amount to such beneficial interest and to have such Junior Subordinated
Debentures registered in its name. Individual Junior Subordinated Debentures of
such series so issued will be issued in denominations, unless otherwise
specified by the Company, of $25 and integral multiples thereof.
 
PAYMENT AND PAYING AGENTS
 
Unless otherwise indicated in the applicable Prospectus Supplement, payment of
principal of (and premium, if any) and any interest on Junior Subordinated
Debentures will be made at the office of the Debenture Trustee in The City of
New York or at the office of such paying agent or paying agents as the Company
may designate from time to time in the applicable Prospectus Supplement, except
that at the option of the Company payment of any interest may be made (i) except
in the case of Global Junior Subordinated Debentures, by check mailed to the
address of the person or entity entitled thereto as such address shall appear in
the Securities Register or (ii) by transfer to an account maintained by the
person or entity entitled thereto as specified in the Securities Register,
provided that proper transfer instructions have been received by the Regular
Record Date. Unless otherwise indicated in the applicable Prospectus Supplement,
payment of any interest on Junior Subordinated Debentures will be made to the
person or entity in whose name such Junior Subordinated Debenture is registered
at the close of business on the Regular Record Date for such interest, except in
the case of Defaulted Interest. The Company may at any time designate additional
paying agents or rescind the designation of any paying agent; however, the
Company will at all times be required to maintain a paying agent in each Place
of Payment for each series of Junior Subordinated Debentures.
 
Any moneys deposited with the Debenture Trustee or any paying agent, or held by
the Company in trust, for the payment of the principal of (and premium, if any)
or interest on any Junior Subordinated Debenture and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall, at the request of the Company, be repaid to the Company or
released from such trust, as applicable, and the holder of such Junior
Subordinated Debenture shall thereafter look, as a general unsecured creditor,
only to the Company for payment thereof.
 
REDEMPTION
 
Unless otherwise indicated in the applicable Prospectus Supplement, Junior
Subordinated Debentures will not be subject to any sinking fund.
 
Unless otherwise indicated in the applicable Prospectus Supplement, the Company
may, at its option, redeem the Junior Subordinated Debentures of any series in
whole at any time or in part from time to time, at the redemption price set
forth in the applicable Prospectus Supplement plus accrued and unpaid interest
to the date fixed for redemption. Junior Subordinated Debentures in
denominations larger than $25 may be redeemed in part but only in integral
multiples of $25. If the Junior Subordinated Debentures of any series are so
redeemable only on or after a specified date or upon the satisfaction of
additional conditions, the applicable Prospectus Supplement will specify such
date or describe such conditions.
 
Except as otherwise specified in the applicable Prospectus Supplement, if a
Debenture Tax Event (as defined below or in the applicable Prospectus
Supplement) in respect of a series of Junior Subordinated Debentures or a
Special Event (as defined in "Description of Preferred Securities --
Redemption -- Mandatory Redemption" below or in the applicable Prospectus
Supplement) in respect of an Issuer shall occur and be continuing, the Company
may, at its option, redeem such series of Junior Subordinated Debentures or the
related series of Corresponding Junior Subordinated Debentures, as the case may
be, in whole (but not in part) within 90 days of the occurrence
 
                                        9
<PAGE>   30
 
of such Debenture Tax Event or Special Event, at a redemption price equal to
100% of the principal amount of such Junior Subordinated Debentures or
Corresponding Junior Subordinated Debentures then outstanding plus accrued and
unpaid interest to the date fixed for redemption.
 
"Debenture Tax Event" means the receipt by the Company of an opinion of counsel
experienced in such matters to the effect that, as a result of (i) any amendment
to, or change (including any announced prospective change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein affecting taxation, (ii) any amendment to or
change in an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority or (iii)
any interpretation or pronouncement that provides for a position with respect to
such laws or regulations that differs from the generally accepted position on
the date the applicable series of Junior Subordinated Debentures is issued,
which amendment or change is effective or which interpretation or pronouncement
is announced on or after the date of issuance of the applicable series of Junior
Subordinated Debentures under the Subordinated Indenture, there is more than an
insubstantial risk that interest payable by the Company on such series of Junior
Subordinated Debentures is not, or within 90 days of the date thereof, will not
be, deductible, in whole or in part, for U.S. federal income tax purposes.
 
Notice of any redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of Junior Subordinated Debentures
to be redeemed at such holder's registered address. Unless the Company defaults
in the payment of the redemption price, on and after the redemption date
interest shall cease to accrue on such Junior Subordinated Debentures or
portions thereof called for redemption.
 
In the recent past, there have been various legislative proposals which, if
enacted, would have prohibited an issuer from deducting interest payments or
original issue discount under certain circumstances. There can be no assurance
that legislation affecting the Company's ability to deduct interest paid on the
Junior Subordinated Debentures or the characterization of the Junior
Subordinated Debentures as indebtedness for U.S. federal income tax purposes,
including legislation similar to the proposals described above, will not be
enacted in the future or that any such legislation would not be effective
retroactively. In the event tax law changes are enacted and apply retroactively
to the Junior Subordinated Debentures, such changes could give rise to a
Debenture Tax Event, which would permit the Company to cause a redemption of
such Junior Subordinated Debentures, as described more fully under
"-- Redemption" or, in the case of Corresponding Junior Subordinated Debentures,
such changes could give rise to a Special Event, which would permit the Company
to cause a redemption of the related Preferred Securities and Common Securities,
as described more fully under "Description of Preferred
Securities -- Redemption -- Special Event Redemption."
 
OPTION TO DEFER INTEREST PAYMENTS
 
If provided in the applicable Prospectus Supplement, the Company shall have the
right at any time and from time to time during the term of any series of Junior
Subordinated Debentures to defer the payment of interest for such number of
consecutive interest payment periods as may be specified in the applicable
Prospectus Supplement (each, an "Extension Period"), subject to the terms,
conditions and covenants, if any, specified in such Prospectus Supplement,
provided that such Extension Period may not extend beyond the Stated Maturity of
the Junior Subordinated Debentures. Certain material U.S. federal income tax
consequences and special considerations applicable to any such Junior
Subordinated Debentures will be described in the applicable Prospectus
Supplement.
 
                                       10
<PAGE>   31
 
RESTRICTIONS ON CERTAIN PAYMENTS
 
The Company will covenant, as to each series of Junior Subordinated Debentures,
that it will not, and will not permit any subsidiary of the Company to, (i)
declare or pay any dividends or distributions on, or redeem, purchase, acquire,
or make a liquidation payment with respect to, any of the Company's capital
stock (other than as a result of a reclassification of such capital stock or the
exchange or conversion of one class or series of capital stock for another class
or series) or (ii) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities (including other Junior
Subordinated Debentures) that rank pari passu with or junior in interest to the
Junior Subordinated Debentures or make any guarantee payments with respect to
the foregoing (in each case other than (a) dividends or distributions in common
stock of the Company, (b) redemptions or purchases of any rights pursuant to the
1996 Rights Agreement (as defined herein), or any successor to such Rights
Agreement, and the declaration thereunder of a dividend of rights in the future,
(c) payments under any Guarantee and (d) guarantee payments to the Company from
a subsidiary thereof) if at such time (x) there shall have occurred any event of
which the Company has actual knowledge (A) that with the giving of notice or the
lapse of time, or both, would constitute a Debenture Event of Default under the
Subordinated Indenture with respect to Junior Subordinated Debentures of such
series and (B) in respect of which the Company shall not have taken reasonable
steps to cure, (y) if such Junior Subordinated Debentures are held by an Issuer
of related Preferred Securities, the Company shall be in default with respect to
its payment of any obligations under the Guarantee relating to such Preferred
Securities or (z) the Company shall have given notice of its selection of an
Extension Period as provided in the Subordinated Indenture with respect to
Junior Subordinated Debentures of such series and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing.
 
MODIFICATION OF SUBORDINATED INDENTURE
 
From time to time the Company and the Debenture Trustee may, without the consent
of the holders of any series of Junior Subordinated Debentures, amend, waive or
supplement the Subordinated Indenture for specified purposes, including, among
other things, curing ambiguities, defects or inconsistencies (provided that any
such action does not materially adversely affect the interest of the holders of
any series of Junior Subordinated Debentures or, in the case of Corresponding
Junior Subordinated Debentures, the holders of the corresponding series of
Preferred Securities so long as they remain outstanding) and qualifying, or
maintaining the qualification of, the Subordinated Indenture under the Trust
Indenture Act. The Subordinated Indenture contains provisions permitting the
Company and the Debenture Trustee, with the consent of the holders of not less
than a majority in principal amount of each outstanding series of Junior
Subordinated Debentures affected, to modify the Subordinated Indenture in a
manner affecting the rights of the holders of such series of the Junior
Subordinated Debentures; provided, that no such modification may, without the
consent of the holder of each outstanding Junior Subordinated Debenture so
affected, (i) change the Stated Maturity of any series of Junior Subordinated
Debentures (except as otherwise specified in the applicable Prospectus
Supplement), or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon (except such extension as may be
contemplated in the applicable Prospectus Supplement) or (ii) reduce the
percentage of principal amount of Junior Subordinated Debentures of any series,
the holders of which are required to consent to any such modification of the
Subordinated Indenture, provided that, in the case of Corresponding Junior
Subordinated Debentures, so long as any of the corresponding series of Preferred
Securities remain outstanding, no such modification may be made that adversely
affects the holders of such Preferred Securities, and no termination of the
Subordinated Indenture may occur, and no waiver of any Debenture Event of
Default or compliance with any covenant under the Subordinated Indenture may be
effective, without the prior consent of the holders of at least a majority of
the aggregate liquidation preference of such Preferred Securities unless and
until the principal of the Corresponding Junior Subordinated Debentures and all
accrued and unpaid
                                       11
<PAGE>   32
 
interest thereon have been paid in full or provided for in accordance with the
Subordinated Indenture.
 
In addition, the Company and the Debenture Trustee may execute, without the
consent of any holder of Junior Subordinated Debentures, any supplemental
Subordinated Indenture for the purpose of creating any new series of Junior
Subordinated Debentures.
 
DEBENTURE EVENTS OF DEFAULT
 
The Subordinated Indenture provides that any one or more of the following
described events with respect to a series of Junior Subordinated Debentures that
has occurred and is continuing constitutes a "Debenture Event of Default" with
respect to such series of Junior Subordinated Debentures:
 
         (i) failure for 30 days to pay any interest on such series of the
     Junior Subordinated Debentures, when due (subject to the deferral of any
     due date in the case of an Extension Period); or
 
         (ii) failure to pay any principal or premium, if any, on such series of
     Junior Subordinated Debentures when due whether at maturity, upon
     redemption, by declaration or otherwise; or
 
        (iii) failure to observe or perform in any material respect certain
     other covenants contained in the Subordinated Indenture for 90 days after
     written notice has been given to the Company from the Debenture Trustee or
     the holders of at least 25% in principal amount of such series of
     outstanding Junior Subordinated Debentures; or
 
        (iv) certain events in bankruptcy, insolvency or reorganization of the
     Company.
 
The holders of a majority in outstanding principal amount of such series of
Junior Subordinated Debentures have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee. The Debenture Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of such series of Junior Subordinated Debentures
may declare the principal due and payable immediately upon a Debenture Event of
Default, and, in the case of Corresponding Junior Subordinated Debentures,
should the Debenture Trustee or such holders of such Corresponding Junior
Subordinated Debentures fail to make such declaration, the holders of at least
25% in aggregate Liquidation Amount (as defined in "Description of Preferred
Securities -- Redemption -- Change of Maturity of Corresponding Junior
Subordinated Debentures" below) of the related Preferred Securities shall have
such right. The holders of a majority in aggregate outstanding principal amount
of such series of Junior Subordinated Debentures may annul such declaration and
waive the default if the default (other than the non-payment of the principal of
such series of Junior Subordinated Debentures which has become due solely by
such acceleration) has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Debenture Trustee. In the case of Corresponding Junior
Subordinated Debentures, should the holders of such Corresponding Junior
Subordinated Debentures fail to so annul such declaration and waive such
default, the holders of a majority in aggregate Liquidation Amount of the
related Preferred Securities shall have such right.
 
The holders of a majority in outstanding principal amount of the Junior
Subordinated Debentures affected thereby may, on behalf of the holders of all
the Junior Subordinated Debentures, waive any past default, except a default in
the payment of principal or interest (unless such default has been cured and a
sum sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
a default in respect of a covenant or provision which under the Subordinated
Indenture cannot be modified or amended without the consent of the holder of
each outstanding Junior Subordinated Debenture. In the case of Corresponding
Junior Subordinated Debentures, should the holders of such Corresponding Junior
Subordinated Debentures fail to so waive such a past default, the holders of a
majority in
                                       12
<PAGE>   33
 
aggregate Liquidation Amount of the related Preferred Securities shall have such
right. The Company is required to file annually with the Debenture Trustee a
certificate as to whether or not the Company is in compliance with all the
conditions and covenants applicable to it under the Subordinated Indenture.
 
In case a Debenture Event of Default shall occur and be continuing as to a
series of Corresponding Junior Subordinated Debentures, the Property Trustee
will have the right to declare the principal of and the interest on such
Corresponding Junior Subordinated Debentures, and any other amounts payable
under the Subordinated Indenture, to be forthwith due and payable and to enforce
its other rights as a creditor with respect to such Corresponding Junior
Subordinated Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
If a Debenture Event of Default with respect to a series of Junior Subordinated
Debentures has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on such Junior Subordinated
Debentures on the date such interest or principal is otherwise payable, a holder
of the related Preferred Securities may institute a legal proceeding directly
against the Company for enforcement of payment to such holder of the principal
of or interest on such Junior Subordinated Debentures having a principal amount
equal to the aggregate Liquidation Amount of the related Preferred Securities of
such holder (a "Direct Action"). The Company may not amend the Subordinated
Indenture to remove the foregoing right to bring a Direct Action without the
prior written consent of the holders of all of the related Preferred Securities.
If the right to bring a Direct Action is removed, the applicable Issuer may
become subject to the reporting obligations under the Exchange Act. The Company
shall have the right under the Subordinated Indenture to set-off any payment
made to such holder of Preferred Securities by the Company in connection with a
Direct Action. The holders of Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the Junior Subordinated
Debentures unless there shall have been an Event of Default under the applicable
Trust Agreement. See "Description of Preferred Securities -- Events of Default;
Notice".
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
The Subordinated Indenture provides that the Company shall not consolidate with
or merge into any other person or entity or sell, assign, convey, transfer or
lease its properties and assets substantially as an entirety to any person or
entity, and no person or entity shall consolidate with or merge into the Company
or sell, assign, convey, transfer or lease its properties and assets
substantially as an entirety to the Company, unless (i) in case the Company
consolidates with or merges into another person or entity or sells, assigns,
conveys, transfers or leases its properties and assets substantially as an
entirety to any person or entity, the successor person or entity is organized
under the laws of the United States or any state or the District of Columbia,
and such successor person or entity expressly assumes the Company's obligations
on the Junior Subordinated Debentures issued under the Subordinated Indenture;
(ii) immediately after giving effect thereto, no Debenture Event of Default, and
no event which, after notice or lapse of time or both, would become a Debenture
Event of Default, shall have happened and be continuing; and (iii) in the case
of Corresponding Junior Subordinated Debentures, such transaction is permitted
under the related Trust Agreement and Guarantee and does not give rise to any
breach or violation of such Trust Agreement or Guarantee.
 
The general provisions of the Subordinated Indenture do not afford holders of
the Junior Subordinated Debentures protection in the event of a highly leveraged
or other transaction involving the Company that may adversely affect holders of
the Junior Subordinated Debentures.
 
                                       13
<PAGE>   34
 
SATISFACTION AND DISCHARGE
 
The Subordinated Indenture provides that when, among other things, all Junior
Subordinated Debentures not previously delivered to the Debenture Trustee for
cancellation (i) have become due and payable or (ii) will become due and payable
at their Stated Maturity within one year, and the Company deposits or causes to
be deposited with the Debenture Trustee, as trust funds in trust for the
purpose, an amount in the currency or currencies in which the Junior
Subordinated Debentures are payable sufficient to pay and discharge the entire
indebtedness on the Junior Subordinated Debentures not previously delivered to
the Debenture Trustee for cancellation, for the principal (and premium, if any)
and interest to the date of the deposit or to the Stated Maturity, as the case
may be, then the Subordinated Indenture will cease to be of further effect
(except as to the Company's obligations to pay all other sums due pursuant to
the Subordinated Indenture and to provide the officers' certificates and
opinions of counsel described therein), and the Company will be deemed to have
satisfied and discharged the Subordinated Indenture.
 
CONVERSION OR EXCHANGE
 
If and to the extent indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures of any series may be convertible or exchangeable
into Preferred Securities or other securities. The specific terms on which
Junior Subordinated Debentures of any series may be so converted or exchanged
will be set forth in the applicable Prospectus Supplement. Such terms may
include provisions for conversion or exchange, either mandatory, at the option
of the holder, or at the option of the Company, in which case the number of
shares of Preferred Securities or other securities to be received by the holders
of Junior Subordinated Debentures would be calculated as of a time and in the
manner stated in the applicable Prospectus Supplement.
 
SUBORDINATION
 
In the Subordinated Indenture, the Company has covenanted and agreed that any
Junior Subordinated Debentures issued thereunder will be subordinate and junior
in right of payment to all Senior Debt to the extent provided in the
Subordinated Indenture. In the event of any dissolution, winding-up, liquidation
or reorganization of the Company (whether voluntary or involuntary and whether
in bankruptcy, insolvency or receivership proceedings, or upon an assignment for
the benefit of creditors or any other marshalling of the assets and liabilities
of the Company or otherwise), all Senior Debt will first be paid in full before
any payment or distribution may be made in respect of the principal of (and
premium, if any) or interest, if any, on the Junior Subordinated Debentures.
 
The Company may not make any payment with respect to the Junior Subordinated
Debentures if and for so long as (i) any Senior Debt is or becomes due and
payable (whether at maturity, for an installment of principal or interest, upon
acceleration, for mandatory prepayment, or otherwise) and remains unpaid; (ii)
any Senior Debt Default (as defined below) has occurred and has not been cured
or waived in conformity with the terms of the instrument, indenture or agreement
governing such Senior Debt; or (iii) a payment by the Company with respect to
the Junior Subordinated Debentures would, immediately after giving effect
thereto, result in a Senior Debt Default.
 
A payment with respect to the Junior Subordinated Debentures shall include,
without limitation, payment of principal of, premium, if any, and interest on
the Junior Subordinated Debentures, the purchase of Junior Subordinated
Debentures by the Company and any other payment other than a payment in stock or
any equity securities.
 
"Senior Debt Default" means the failure to make any payment of any Senior Debt
when due or the happening of an event of default with respect to any Senior
Debt, as defined therein or in the instrument under which the same is
outstanding, which, by its terms, if occurring prior to the stated maturity of
such Senior Debt, permits or with the giving of notice or lapse of time (or
both) would permit any holder thereof, any group of such holders or any trustee
or representative for such
                                       14
<PAGE>   35
 
holders thereupon to accelerate the maturity thereof or which results in such
acceleration, including, without limitation, a "Default" under the Credit
Agreement, dated as of November 2, 1993 (the "Credit Agreement"), by and among
the Company, the several financial institutions listed on Annex A thereof and
Credit Suisse, as Agent, as in effect and as amended, renewed, extended or
supplemented from time to time, and any document, instrument or agreement
executed and delivered in connection therewith, whether or not such Senior Debt
or instrument has been avoided, disallowed or subordinated.
 
"Senior Debt" means all indebtedness incurred, assumed or guaranteed, directly
or indirectly, by the Company, either before, on, or after the date of the
Subordinated Indenture without any limitation as to the amount or terms thereof,
and whether such indebtedness (including, but not limited to, interest on any
such indebtedness) arises or accrues before or after the commencement of any
bankruptcy, insolvency or receivership proceedings, (i) which arises for
borrowed money, securities sold, funds provided, assets or services purchased or
any other transaction whether or not in the ordinary course of business and
which is evidenced by a promissory note, bond, debenture, writing or other
instrument of indebtedness or reflected on the accounting records of the Company
as a payable (but expressly excluding (A) amounts owed for compensation to
employees, (B) obligations owing under judgments arising out of obligations that
are not indebtedness for borrowed money (other than any such obligations arising
from obligations which are otherwise Senior Debt), (C) any indebtedness which by
the terms of the instrument creating or evidencing the same is not superior in
right of payment to or is junior in right of payment to the Junior Subordinated
Debentures, (D) any liability for federal, state, local or other taxes owed or
owing by the Company, (E) any liability in respect of any employee benefit plan
(including, without limitation, any liability to the Pension Benefit Guaranty
Corporation or any successor thereto), (F) indebtedness or obligations to a
subsidiary of the Company, (G) the Convertible Subordinated Debentures) and (H)
indebtedness to trade creditors or monetary obligations to trade creditors
incurred or assumed by the Company or any of its subsidiaries in the ordinary
course of business; (ii) for principal of and interest on all loans and other
extensions of credit under the Credit Agreement, as in effect and as amended,
renewed, extended or supplemented from time to time, and any document,
instrument or agreement executed and delivered in connection therewith and all
fees, expenses, reimbursements, indemnities, premiums and other amounts payable
under the Credit Agreement; (iii) for principal of (and premium, if any) and
interest on the Company's 5 3/8% Swiss Franc Bonds due November 26, 2000 and the
Company's 7 1/4% DM Bonds of 1985/2000 and all fees, expenses, reimbursements,
indemnities, premiums and other amounts payable thereunder; (iv) for any amount
payable with respect to any lease, conditional sale or installment sale
agreement or other financing instrument or agreement which in accordance with
generally accepted accounting principles is, at the date of the Subordinated
Indenture or at the time the lease, conditional sale or installment sale
agreement or other financing instrument or agreement is entered into, assumed or
guaranteed, directly or indirectly, by the Company, required to be reflected as
a liability on the face of the balance sheet of the Company; (v) for all
principal of and interest on all loans and other extensions of credit under any
lines of credit, credit agreements or promissory notes from a bank or other
financial institution (including, without limitation, any letters of credit,
bankers' acceptances, performance bonds and other credit facilities under such
borrowing arrangements), and all fees, expenses, reimbursements, indemnities,
premiums and other amounts payable under such borrowing arrangements; (vi) for
any amounts payable in respect of any interest rate exchange agreement, ceiling
rate agreement, currency exchange agreement or similar agreement; and (vii) for
renewals, deferrals, amendments, modifications, supplements, extensions or
refundings of any of the indebtedness described in clauses (i) through (vi),
inclusive, or evidences of indebtedness issued in exchange for such Senior Debt.
Senior Debt shall continue to constitute Senior Debt for all purposes of the
Junior Subordinated Debentures, and the provisions of Article XIII of the
Subordinated Indenture shall continue to apply to such Senior Debt,
notwithstanding the fact that such Senior Debt or any claim in respect thereof
shall be disallowed,
 
                                       15
<PAGE>   36
 
avoided or subordinated pursuant to the provisions of the United States
Bankruptcy Code of 1978, as amended, or other applicable law.
 
The Subordinated Indenture places no limitation on the amount of additional
Senior Debt that may be incurred by the Company. The Company expects from time
to time to incur additional indebtedness constituting Senior Debt.
 
The Subordinated Indenture provides that the foregoing subordination provisions,
insofar as they relate to any particular issue of Junior Subordinated
Debentures, may be changed prior to such issuance. Any such change would be
described in the Prospectus Supplement relating to such Junior Subordinated
Debentures.
 
GOVERNING LAW
 
The Subordinated Indenture and the Junior Subordinated Debentures will be
governed by and construed in accordance with the laws of the State of New York.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
The Debenture Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the Debenture Trustee is under no
obligation to exercise any of the powers vested in it by the Subordinated
Indenture at the request of any holder of Junior Subordinated Debentures, unless
offered reasonable indemnity by such holder against the costs, expenses and
liabilities which might be incurred thereby. The Debenture Trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties if the Debenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
 
Wilmington Trust Company, the Debenture Trustee, is also Property Trustee and
Delaware Trustee under each Trust Agreement and Guarantee Trustee under each
Guarantee. The Company maintains trust and other business relationships in the
ordinary course of business with Wilmington Trust Company. Pursuant to the
provisions of the TIA, upon the occurrence of certain events, Wilmington Trust
Company may be deemed to have a conflicting interest, by virtue of its acting as
the Property Trustee, the Delaware Trustee, the Debenture Trustee and the
Guarantee Trustee, and its other business relationships with the Company, and
thereby may be required to resign and be replaced by a successor trustee under
the Junior Subordinated Indenture, each Trust Agreement and each Guarantee.
 
CORRESPONDING JUNIOR SUBORDINATED DEBENTURES
 
  General
 
The Corresponding Junior Subordinated Debentures are to be issued in one or more
series of Junior Subordinated Debentures under the Subordinated Indenture with
terms corresponding to the terms of the related Preferred Securities.
Concurrently with the issuance of an Issuer's Preferred Securities, such Issuer
will invest the proceeds thereof and the consideration paid by the Company for
the related Common Securities in a series of Corresponding Junior Subordinated
Debentures issued by the Company to such Issuer. Each series of Corresponding
Junior Subordinated Debentures will be in the principal amount equal to the
aggregate stated Liquidation Amount of the related Preferred Securities plus the
Company's concurrent investment in the related Common Securities and will rank
pari passu with the Convertible Subordinated Debentures and with all other
series of Junior Subordinated Debentures, if any. The Corresponding Junior
Subordinated Debentures will be unsecured and subordinate and junior in right of
payment to the extent and in the manner set forth in the Subordinated Indenture
to all Senior Debt of the Company. See "--Subordination" and the Prospectus
Supplement relating to any offering of corresponding Preferred Securities.
Holders of Preferred Securities relating to a series of Corresponding Junior
Subordi-
 
                                       16
<PAGE>   37
 
nated Debentures will have the rights in connection with modifications to the
Subordinated Indenture or upon occurrence of Debenture Events of Default
described under "-- Modification of Indenture", "-- Debenture Events of
Default", and "-- Enforcement of Certain Rights by Holders of Preferred
Securities", unless otherwise provided in the applicable Prospectus Supplement.
 
  Optional Redemption
 
Unless otherwise specified in the applicable Prospectus Supplement, if a Special
Event in respect of an Issuer shall occur and be continuing, the Company may, at
its option, redeem the Corresponding Junior Subordinated Debentures at any time
within 90 days of the occurrence of such Special Event, in whole but not in
part, subject to the provisions of the Subordinated Indenture. The redemption
price for such Corresponding Junior Subordinated Debentures shall be equal to
100% of the principal amount of such Corresponding Junior Subordinated
Debentures then outstanding plus accrued and unpaid interest to the date fixed
for redemption. Unless otherwise specified in the applicable Prospectus
Supplement, the Company also may, at its option, redeem Corresponding Junior
Subordinated Debentures in whole at any time or in part from time to time. See
"Description of Junior Subordinated Debentures -- Redemption".
 
For so long as the applicable Issuer is the holder of all the outstanding series
of Corresponding Junior Subordinated Debentures, the proceeds of any redemption
thereof will be used by such Issuer to redeem the corresponding Trust Securities
in accordance with their terms. The Company may not redeem a series of
Corresponding Junior Subordinated Debentures in part unless all accrued and
unpaid interest has been paid in full on all outstanding Corresponding Junior
Subordinated Debentures of such series for all interest periods terminating on
or prior to the Redemption Date.
 
  Certain Covenants of the Company
 
The Company will covenant in the Subordinated Indenture, as to each series of
Corresponding Junior Subordinated Debentures, that if and for so long as (i) the
Issuer of the corresponding Trust Securities is the holder of all such
Corresponding Junior Subordinated Debentures, (ii) a Tax Event (as defined in
"Description of Preferred Securities -- Redemption -- Change of Maturity of
Corresponding Junior Subordinated Debentures" or in the applicable Prospectus
Supplement) in respect of such Issuer has occurred and is continuing and (iii)
the Company has not elected to redeem such corresponding Junior Subordinated
Debentures or to liquidate such Issuer, the Company will pay to such Issuer
Additional Sums (as defined in "Description of Preferred
Securities -- Redemption -- Change of Maturity of Corresponding Junior
Subordinated Debentures" or in the applicable Prospectus Supplement) in respect
of such Trust Securities. The Company will also covenant, as to each series of
Corresponding Junior Subordinated Debentures, (i) to maintain directly or
indirectly 100% ownership of the Common Securities of the Issuer in respect of
which such Corresponding Junior Subordinated Debentures have been issued,
provided that certain successors which are permitted pursuant to the
Subordinated Indenture may succeed to the Company's ownership of the Common
Securities, (ii) not to voluntarily terminate, wind-up or liquidate the
applicable Issuer, except (a) in connection with a distribution of Corresponding
Junior Subordinated Debentures to the holders of such Issuer's Preferred
Securities in liquidation of such Issuer, or (b) in connection with certain
mergers, consolidations or amalgamations permitted by the related Trust
Agreement and (iii) to use its reasonable efforts, consistent with the terms and
provisions of the related Trust Agreement, to cause such Issuer to remain a
grantor trust for U.S. federal income tax purposes.
 
                      DESCRIPTION OF PREFERRED SECURITIES
 
Pursuant to the terms of the Trust Agreement for each Issuer, the Issuer
Trustees on behalf of such Issuer will issue the Preferred Securities and the
Common Securities. The Preferred Securities of a

particular issue will represent preferred undivided beneficial interests in the
assets of the related Issuer and the holders thereof will be entitled to a
preference in certain circumstances with respect to Distributions and amounts
payable on redemption or liquidation over the Common Securities of such Issuer,
as well as other benefits as described in the applicable Trust Agreement. This
summary of certain provisions of the Preferred Securities and each Trust
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of each Trust Agreement,
including the definitions therein of certain terms, and the Trust Indenture Act.
Wherever particular defined terms of a Trust Agreement are referred to in this
Section or in a Prospectus Supplement, such defined terms are incorporated
herein by reference. The form of Trust Agreement has been filed as an exhibit to
the Registration Statement of which this Prospectus forms a part. Each of the
Issuers is a legally separate entity and the assets of one Issuer are not
available to satisfy the obligations of the other Issuer.
 
GENERAL
 
The Preferred Securities of an Issuer will rank pari passu, and payments will be
made thereon pro rata, with the Common Securities of that Issuer except as
described under "-- Subordination of Common Securities". Legal title to the
Corresponding Junior Subordinated Debentures will be held by the Property
Trustee in trust for the benefit of the holders of the related Preferred
Securities and Common Securities. Each Guarantee Agreement executed by the
Company for the benefit of the holders of an Issuer's Preferred Securities
(each, a "Guarantee") will be a guarantee on a subordinated basis with respect
to the related Preferred Securities but will not guarantee payment of
Distributions or amounts payable on redemption or liquidation of such Preferred
Securities when the related Issuer does not have funds on hand available to make
such payments. See "Description of Guarantees".
 
DISTRIBUTIONS
 
Each Issuer's Preferred Securities represent preferred undivided beneficial
interests in the assets of such Issuer, and the Distributions on each Preferred
Security will be payable at a rate specified in the Prospectus Supplement for
such Preferred Securities. The amount of Distributions payable for any period
will be computed on the basis of a 360-day year of twelve 30-day months unless
otherwise specified in the applicable Prospectus Supplement. Distributions that
are in arrears will accumulate additional Distributions thereon at the rate per
annum if and as specified in the applicable Prospectus Supplement ("Additional
Amounts"). The term "Distributions" as used herein includes any Additional
Amounts unless otherwise stated.
 
Distributions on the Preferred Securities will be cumulative, will accumulate
from the date of original issuance and will be payable on such dates as
specified in the applicable Prospectus Supplement. In the event that any date on
which Distributions are payable on the Preferred Securities is not a Business
Day (as defined below), payment of the Distribution payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
is in the next succeeding calendar year, payment of such Distribution shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date (each date on which Distributions are payable
in accordance with the foregoing, a "Distribution Date"). A "Business Day" shall
mean any day other than a Saturday or a Sunday, or a day on which banking
institutions in The City of New York are authorized or required by law or
executive order to remain closed or a day on which the corporate trust office of
the Property Trustee or the Debenture Trustee is closed for business.
 
If provided in the applicable Prospectus Supplement, the Company has the right
under the Subordinated Indenture, pursuant to which it will issue the
Corresponding Junior Subordinated Debentures, to defer the payment of interest
at any time and from time to time on any series of the Corresponding Junior
Subordinated Debentures, for a period which will be specified in such
                                       18
<PAGE>   39
 
Prospectus Supplement relating to such series (each, an "Extension Period"),
provided that no Extension Period may extend beyond the Stated Maturity of the
Corresponding Junior Subordinated Debentures. As a consequence of any such
deferral, Distributions on the corresponding Preferred Securities would be
deferred (but would continue to accumulate additional Distributions thereon at
the rate per annum if and as specified in the Prospectus Supplement for such
Preferred Securities) by the Issuer of such Preferred Securities during any such
Extension Period. In the event that the Company exercises this right, during
such Extension Period the Company may not, and may not permit any subsidiary of
the Company to, (i) declare or pay any dividends or distributions on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of the
Company's capital stock (other than as a result of a reclassification of such
capital stock or the exchange or conversion of one class or series of capital
stock for another class or series) or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities that rank pari passu with or junior in interest to the Corresponding
Junior Subordinated Debentures or make any guarantee payments with respect to
the foregoing (in each case other than (a) dividends or distributions in common
stock of the Company, (b) redemptions or purchases of any rights pursuant to the
1996 Rights Agreement, or any successor to such Rights Agreement, and the
declaration thereunder of a dividend of rights in the future, (c) payments under
any Guarantee and (d) guarantee payments to the Company from a subsidiary
thereof).
 
It is anticipated that the revenue of each Issuer available for distribution to
holders of its Preferred Securities will be limited to payments under the
Corresponding Junior Subordinated Debentures in which such Issuer will invest
the proceeds from the issuance and sale of its Preferred Securities and its
Common Securities. See "Description of Junior Subordinated
Debentures -- Corresponding Junior Subordinated Debentures". If the Company does
not make interest payments on such Corresponding Junior Subordinated Debentures,
the Property Trustee will not have funds available to pay Distributions on the
corresponding Preferred Securities. The payment of Distributions (if and to the
extent an Issuer has funds legally available for the payment of such
Distributions and cash sufficient to make such payments) is guaranteed by the
Company on a limited basis as set forth herein under "Description of
Guarantees".
 
Distributions on the Preferred Securities will be payable to the holders thereof
as they appear on the register of the applicable Issuer on the relevant record
dates, which, as long as the Preferred Securities remain in book-entry form,
will be one Business Day prior to the relevant Distribution Date. Subject to any
applicable laws and regulations and the provisions of the applicable Trust
Agreement, each such payment will be made as described under "Book-Entry
Issuance". In the event any Preferred Securities are not in book-entry form, the
relevant record date for such Preferred Securities shall be the date, at least
15 days prior to the relevant Distribution Date, that is specified in the
applicable Prospectus Supplement.
 
REDEMPTION
 
  Mandatory Redemption
 
Upon the repayment or redemption, in whole or in part, of any Corresponding
Junior Subordinated Debentures, whether at maturity or upon earlier redemption
as provided in the Subordinated Indenture, the proceeds from such repayment or
redemption shall be applied by the Property Trustee to redeem a Like Amount (as
defined below) of the related Trust Securities, upon not less than 30 nor more
than 60 days notice, at a redemption price (the "Redemption Price") equal to the
aggregate Liquidation Amount of such Trust Securities plus accumulated and
unpaid Distributions thereon to the date of redemption (the "Redemption Date")
and the related amount of the premium, if any, paid by the Company upon the
concurrent redemption of such Corresponding Junior Subordinated Debentures. See
"Description of Junior Subordinated Debentures -- Corresponding Junior
Subordinated Debentures -- Optional Redemption". If less than all of any series
of Corresponding Junior Subordinated Debentures are to be repaid or redeemed on
a Redemption Date, then the proceeds from such repayment or redemption shall be
allocated to the redemption
 
                                       19
<PAGE>   40
 
pro rata of the related Preferred Securities and the related Common Securities.
The amount of premium, if any, paid by the Company upon the redemption of all or
any part of any series of any Corresponding Junior Subordinated Debentures to be
repaid or redeemed on a Redemption Date shall be allocated to the redemption pro
rata of the related Preferred Securities and the related Common Securities.
 
The Company will have the right to redeem any series of Corresponding Junior
Subordinated Debentures (i) in whole at any time or in part from time to time,
at the redemption price described under "Description of Junior Subordinated
Debentures -- Redemption", (ii) in whole (but not in part), within 90 days of
the occurrence of a Tax Event or an Investment Company Event (each as defined
below or in the applicable Prospectus Supplement, a "Special Event"), at the
redemption price described under "Description of Junior Subordinated
Debentures -- Corresponding Junior Subordinated Debentures -- Optional
Redemption", or (iii) as may be otherwise specified in the applicable Prospectus
Supplement.
 
  Distribution of Corresponding Junior Subordinated Debentures
 
The Company has the right at any time to dissolve an Issuer and, after
satisfaction of the liabilities of creditors of such Issuer as provided by
applicable law, to cause the Corresponding Junior Subordinated Debentures in
respect of the Trust Securities issued by such Issuer to be distributed to the
holders of such Trust Securities in liquidation of such Issuer.
 
After the liquidation date fixed for any distribution of Corresponding Junior
Subordinated Debentures for any Preferred Securities of an Issuer (i) such
Preferred Securities will no longer be deemed to be outstanding, (ii) the
Depositary (if any) for such Preferred Securities, as the record holder of such
Preferred Securities, will receive a registered global certificate or
certificates representing the Corresponding Junior Subordinated Debentures to be
delivered upon such distribution and (iii) any certificates representing such
Preferred Securities not held by or on behalf of such Depositary will be deemed
to represent the Corresponding Junior Subordinated Debentures having a principal
amount equal to the Liquidation Amount of such Preferred Securities, and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on such Preferred Securities, until such certificates are
presented to the Administrative Trustees or their agent for transfer or
reissuance.
 
There can be no assurance as to the market prices for the Preferred Securities
or the Corresponding Junior Subordinated Debentures that may be distributed in
exchange for Preferred Securities if a dissolution or liquidation of an Issuer
were to occur. Accordingly, the Preferred Securities that an investor may
purchase, or the Corresponding Junior Subordinated Debentures that the investor
may receive on dissolution or liquidation of an Issuer, may trade at a discount
to the price that the investor paid to purchase the Preferred Securities offered
hereby.
 
  Special Event Redemption
 
If a Special Event in respect of the Trust Securities of an Issuer shall occur
and be continuing, the Company will have the right to redeem the Corresponding
Junior Subordinated Debentures in whole (but not in part) and therefore cause a
mandatory redemption of such Trust Securities in whole (but not in part) at the
Redemption Price within 90 days following the occurrence of such Special Event.
If a Special Event in respect of the Trust Securities of an Issuer has occurred
and is continuing and the Company does not elect to redeem the Corresponding
Junior Subordinated Debentures and thereby cause a mandatory redemption of such
Trust Securities, or to dissolve such Issuer and, after satisfaction of the
liability to creditors of such Issuer as provided by applicable law, cause the
Corresponding Junior Subordinated Debentures to be distributed to holders of
such Trust Securities in liquidation of such Issuer, the applicable Preferred
Securities will remain outstanding and, in the event a Tax Event has occurred
and is continuing, unless otherwise
 
                                       20
<PAGE>   41
 
specified in the applicable Prospectus Supplement, Additional Sums, if any, will
be payable on the Corresponding Junior Subordinated Debentures.
 
  Change of Maturity of Corresponding Junior Subordinated Debentures
 
If provided in the applicable Prospectus Supplement, the Company shall have the
right to extend or shorten the maturity of any series of Corresponding Junior
Subordinated Debentures at the time that the Company exercises its right to
elect to dissolve the related Issuer and, after satisfaction of the liability to
creditors of such Issuer as provided by applicable law, cause such Corresponding
Junior Subordinated Debentures to be distributed to the holders of the Preferred
Securities and Common Securities of such Issuer in liquidation of such Issuer,
provided that it can extend the maturity only if certain conditions specified in
the applicable Prospectus Supplement are met at the time such election is made
and at the time of such extension.
 
"Additional Sums" means the additional amounts as may be necessary in order that
the amount of Distributions then due and payable by an Issuer on the outstanding
Preferred Securities and Common Securities of such Issuer shall not be reduced
as a result of any additional taxes, duties and other governmental charges to
which such Issuer has become subject as a result of a Tax Event (other than
withholding taxes).
 
"Tax Event" means the receipt by an Issuer of an opinion of counsel experienced
in such matters to the effect that, as a result of (i) any amendment to, or
change (including any announced prospective change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein affecting taxation, (ii) any amendment to or
change in an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority or (iii)
any interpretation or pronouncement that provides for a position with respect to
such laws or regulations that differs from the generally accepted position on
the date the applicable Preferred Securities are issued, which amendment or
change is effective or which interpretation or pronouncement is announced on or
after the date of issuance of the applicable Preferred Securities under the
Trust Agreement, there is more than an insubstantial risk that (x) the
applicable Issuer is, or will be within 90 days of the date thereof, subject to
U.S. federal income tax with respect to income received or accrued on the
Corresponding Junior Subordinated Debentures, (y) interest payable by the
Company on such Corresponding Junior Subordinated Debentures is not, or within
90 days of the date thereof, will not be, deductible, in whole or in part, for
U.S. federal income tax purposes, or (z) such Issuer is, or will be within 90
days of the date thereof, subject to more than a de minimis amount of other
taxes, duties or other governmental charges.
 
"Investment Company Event" means the occurrence of a change in law or regulation
or a change in interpretation or application of law or regulation by any
legislative body, court, governmental agency or regulatory authority (a "Change
in 1940 Act Law") to the effect that the applicable Issuer is or will be
considered an "investment company" that is required to be registered under the
Investment Company Act of 1940, as amended (the "Investment Company Act"), which
Change in 1940 Act Law becomes effective on or after the date of original
issuance of the applicable Preferred Securities.
 
"Like Amount" means (i) with respect to a redemption of any Trust Securities of
an Issuer, Trust Securities of such Issuer having a Liquidation Amount equal to
that portion of the principal amount of Corresponding Junior Subordinated
Debentures to be contemporaneously redeemed in accordance with the Subordinated
Indenture, allocated to the Common Securities and to the Preferred Securities
based upon the relative Liquidation Amounts of such classes of Trust Securities,
and the proceeds of which will be used to pay the Redemption Price of such Trust
Securities, and (ii) with respect to a distribution of Corresponding Junior
Subordinated Debentures to holders of any Trust Securities of an Issuer in
connection with a dissolution or liquidation of such Issuer, Corresponding
Junior Subordinated Debentures having a principal amount equal to the
Liquidation Amount of the
 
                                       21
<PAGE>   42
 
Trust Securities of the holder to whom such Corresponding Junior Subordinated
Debentures are distributed. "Liquidation Amount" means the stated amount of $25
per Preferred Security and Common Security.
 
REDEMPTION PROCEDURES
 
Preferred Securities redeemed on each Redemption Date shall be redeemed at the
Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Corresponding Junior Subordinated Debentures. Redemptions of
Preferred Securities shall be made and the Redemption Price shall be payable on
each Redemption Date only to the extent that the related Issuer has funds on
hand available for the payment of such Redemption Price. See also "--
Subordination of Common Securities".
 
If an Issuer gives a notice of redemption in respect of its Preferred
Securities, then, on the Redemption Date, to the extent funds are available, the
Property Trustee will deposit irrevocably with the Depositary for such Preferred
Securities (if such Preferred Securities are issued in the form of one or more
Global Preferred Securities) funds sufficient to pay the applicable Redemption
Price and will give such Depository irrevocable instructions and authority to
pay the Redemption Price to the beneficial owners of such Preferred Securities.
See "-- Global Preferred Securities" and "Book-Entry Issuance". If such
Preferred Securities are not issued in the form of one or more Global Preferred
Securities, such Issuer, to the extent funds are available, will irrevocably
deposit with the paying agent for such Preferred Securities funds sufficient to
pay the applicable Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the Redemption Price to the holders thereof
upon surrender of their certificates evidencing such Preferred Securities.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Preferred Securities called for redemption shall be
payable to the holders of such Preferred Securities on the relevant record dates
for the related Distribution Dates. If notice of redemption shall have been
given and funds deposited as required, then upon the date of such deposit, all
rights of the holders of such Preferred Securities so called for redemption will
cease, except the right of the holders of such Preferred Securities to receive
the Redemption Price, but without interest on such Redemption Price, and such
Preferred Securities will cease to be outstanding. In the event that any date
fixed for redemption of Preferred Securities is not a Business Day, then payment
of the Redemption Price payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that, if such Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day. In the event that payment of the Redemption Price in respect of Preferred
Securities called for redemption is improperly withheld or refused and not paid
either by the applicable Issuer or by the Company pursuant to the applicable
Guarantee as described under "Description of Guarantees", Distributions on such
Preferred Securities will continue to accumulate at the then applicable rate,
from the Redemption Date originally established by such Issuer for such
Preferred Securities to the date such Redemption Price is actually paid, in
which case the actual payment date will be the date fixed for redemption for
purposes of calculating the Redemption Price.
 
Subject to applicable law (including, without limitation, U. S. federal
securities law), the Company or its subsidiaries may at any time and from time
to time purchase outstanding Preferred Securities by tender, in the open market
or by private agreement.
 
If less than all of the Preferred Securities and Common Securities issued by an
Issuer are to be redeemed on a Redemption Date, then the aggregate Liquidation
Amount of such Preferred Securities and Common Securities to be redeemed shall
be allocated pro rata among the Preferred Securities and Common Securities of
such Issuer based on the relative Liquidation Amounts of such classes of Trust
Securities. The particular Preferred Securities to be redeemed shall be selected
on a pro rata basis not more than 60 days prior to the Redemption Date by the
Property Trustee from the outstanding Preferred Securities not previously called
for redemption, by such
                                       22
<PAGE>   43
 
method as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $25 or an
integral multiple of $25 in excess thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $25. The Property Trustee
shall promptly notify the registrar in writing of the Preferred Securities
selected for redemption and, in the case of any Preferred Securities selected
for partial redemption, the Liquidation Amount thereof to be redeemed. For all
purposes of each Trust Agreement, unless the context otherwise requires, all
provisions relating to the redemption of Preferred Securities shall relate, in
the case of any Preferred Securities redeemed or to be redeemed only in part, to
the portion of the aggregate Liquidation Amount of Preferred Securities which
has been or is to be redeemed.
 
Notice of any redemption will be mailed at least 30 days but not more than 60
days before the Redemption Date to each holder of Preferred Securities to be
redeemed at its registered address. Unless the Company defaults in payment of
the Redemption Price on the Junior Subordinated Debentures, on and after the
Redemption Date interest will cease to accrue on the Junior Subordinated
Debentures or portions thereof (and Distributions will cease to accumulate on
the Preferred Securities or portions thereof) called for redemption.
 
POSSIBLE TAX LAW CHANGES
 
See "Description of Junior Subordinated Debentures -- Redemption".
 
SUBORDINATION OF COMMON SECURITIES
 
Payment of Distributions (including Additional Amounts, if applicable) on, and
the Redemption Price of, each Issuer's Preferred Securities and Common
Securities, as applicable, shall be made pro rata based on the Liquidation
Amount of such Preferred Securities and Common Securities; provided, however,
that if on any Distribution Date or Redemption Date a Debenture Event of Default
shall have occurred and be continuing, no payment of any Distribution (including
Additional Amounts, if applicable) on, or Redemption Price of, any of such
Issuer's Common Securities, and no other payment on account of the redemption,
liquidation or other acquisition of such Common Securities, shall be made unless
payment in full in cash of all accumulated and unpaid Distributions (including
Additional Amounts, if applicable) on all of such Issuer's outstanding Preferred
Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all of such Issuer's outstanding Preferred Securities then called for
redemption, shall have been made or provided for, and all funds available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or Redemption
Price of, such Issuer's Preferred Securities then due and payable.
 
In the case of any Event of Default under a Trust Agreement resulting from a
Debenture Event of Default, the Company as holder of the applicable Issuer's
Common Securities will be deemed to have waived any right to act with respect to
any such Event of Default under such Trust Agreement until the effect of all
such Events of Default with respect to the applicable Preferred Securities have
been cured, waived or otherwise eliminated. Until any such Events of Default
under such Trust Agreement have been so cured, waived or otherwise eliminated,
the Property Trustee shall act solely on behalf of the holders of such Preferred
Securities and not on behalf of the Company as holder of such Issuer's Common
Securities, and only the holders of such Preferred Securities will have the
right to direct the Property Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
Pursuant to each Trust Agreement, the applicable Issuer shall automatically
dissolve upon expiration of its term and shall be dissolved by the Company on
the first to occur of: (i) the occurrence of certain events of bankruptcy,
dissolution or liquidation of the Company; (ii) the receipt by the
 
                                       23
<PAGE>   44
 
Property Trustee of written direction from the Company to dissolve such Issuer
(which direction is optional and wholly within the discretion of the Company as
Depositor); (iii) the redemption of all of such Issuer's Preferred Securities;
and (iv) an order for the dissolution of such Issuer shall have been entered by
a court of competent jurisdiction.
 
If an early dissolution occurs as described in clause (i), (ii) or (iv) above,
the applicable Issuer shall be liquidated by the Issuer Trustees as
expeditiously as the Issuer Trustees determine to be possible by distributing,
after satisfaction of liabilities to creditors of such Issuer as provided by
applicable law, to the holders of the applicable Trust Securities a Like Amount
of the Corresponding Junior Subordinated Debentures, unless such distribution is
determined by the Property Trustee not to be practical, in which event such
holders will be entitled to receive out of the assets of such Issuer available
for distribution to holders, after satisfaction of liabilities to creditors of
such Issuer as provided by applicable law, an amount equal to, in the case of
holders of Preferred Securities, the aggregate of the Liquidation Amount plus
accrued and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If such Liquidation Distribution can be
paid only in part because such Issuer has insufficient assets available to pay
in full the aggregate Liquidation Distribution, then the amounts payable
directly by such Issuer on its Preferred Securities shall be paid on a pro rata
basis. The holder(s) of such Issuer's Common Securities will be entitled to
receive distributions upon any such liquidation pro rata with the holders of its
Preferred Securities, except that if a Debenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities. A supplemental Subordinated Indenture may provide that if an
early termination occurs as described in clause (iv) above, the Corresponding
Junior Subordinated Debentures may be subject to optional redemption in whole
(but not in part).
 
EVENTS OF DEFAULT; NOTICE
 
Any one of the following events constitutes an "Event of Default" under each
Trust Agreement (an "Event of Default") with respect to the Preferred Securities
issued thereunder (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):
 
        (i) the occurrence of a Debenture Event of Default under the
     Subordinated Indenture (see "Description of Junior Subordinated
     Debentures -- Debenture Events of Default"); or
 
        (ii) default by the Property Trustee in the payment of any Distribution
     when it becomes due and payable, and continuation of such default for a
     period of 30 days; or
 
        (iii) default by the Property Trustee in the payment of any Redemption
     Price of any Trust Security when it becomes due and payable; or
 
        (iv) default in the performance, or breach, in any material respect, of
     any covenant or warranty of the Issuer Trustees in such Trust Agreement
     (other than a covenant or warranty a default in the performance of which or
     the breach of which is dealt with in clause (ii) or (iii) above), and
     continuation of such default or breach for a period of 90 days after
     written notice has been given to the defaulting Issuer Trustee or Trustees
     by the holders of at least 25% in aggregate Liquidation Amount of the
     outstanding Preferred Securities, which notice shall specify such default
     or breach and require it to be remedied and shall state that such notice is
     a "Notice of Default" under such Trust Agreement; or
 
        (v) the occurrence of certain events of bankruptcy or insolvency with
     respect to the Property Trustee and the failure by the Company to appoint a
     successor Property Trustee within 60 days thereof.
 
Within five Business Days after the occurrence of any Event of Default actually
known to the Property Trustee, the Property Trustee shall transmit notice of
such Event of Default to the holders of the applicable Issuer's Preferred
Securities, the Administrative Trustees and the Company, as
                                       24
<PAGE>   45
 
Depositor, unless such Event of Default shall have been cured or waived. The
Company, as Depositor, and the Administrative Trustees are required to file
annually with the Property Trustee a certificate as to whether or not they are
in compliance with all the conditions and covenants applicable to them under the
applicable Trust Agreement.
 
If a Debenture Event of Default has occurred and is continuing, the Preferred
Securities of an Issuer shall have a preference over the Common Securities of
such Issuer upon termination of such Issuer as described above. See "--
Liquidation Distribution Upon Termination." The existence of an Event of Default
does not entitle the holders of Preferred Securities to accelerate the maturity
thereof.
 
REMOVAL OF ISSUER TRUSTEES
 
Unless a Debenture Event of Default shall have occurred and be continuing, any
Issuer Trustee may be removed at any time by the holder of the Common
Securities. If a Debenture Event of Default with respect to any series of
Corresponding Junior Subordinated Debentures has occurred and is continuing, the
Property Trustee and the Delaware Trustee may be removed at such time by the
holders of a majority in Liquidation Amount of the outstanding Preferred
Securities of the relevant Issuer. In no event will the holders of the Preferred
Securities of an Issuer have the right to vote to appoint, remove or replace the
Administrative Trustees, which voting rights are vested exclusively in the
Company as the holder of the Common Securities of such Issuer. No resignation or
removal of an Issuer Trustee and no appointment of a successor trustee shall be
effective until the acceptance of appointment by the successor trustee in
accordance with the provisions of the applicable Trust Agreement.
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
Unless an Event of Default with respect to the Preferred Securities of an Issuer
shall have occurred and be continuing, at any time or times, for the purpose of
meeting the legal requirements of the Trust Indenture Act or of any jurisdiction
in which any part of the Trust Property may at the time be located, the Company,
as the holder of the Common Securities of such Issuer, and the Administrative
Trustees shall have power to appoint one or more persons either to act as a
co-trustee, jointly with the Property Trustee, of all or any part of such Trust
Property, or to act as separate trustee of any such property, in either case
with such powers as may be provided in the instrument of appointment, and to
vest in such person or persons in such capacity any property, title, right or
power deemed necessary or desirable, subject to the provisions of the applicable
Trust Agreement. In case a Debenture Event of Default has occurred and is
continuing, the Property Trustee alone shall have power to make such
appointment.
 
MERGER OR CONSOLIDATION OF ISSUER TRUSTEES
 
Any entity into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
entity succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee under the Trust Agreements,
provided such entity shall be otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE ISSUERS
 
An Issuer may not merge with or into, consolidate, amalgamate, or be replaced
by, or convey, transfer or lease its properties and assets substantially as an
entirety to any corporation or other body, except as described below. An Issuer
may, at the request of the Company, with the consent of the Administrative
Trustees and without the consent of the holders of its Preferred Securities,
merge with or into, consolidate, amalgamate, or be replaced by or convey,
transfer or lease its
 
                                       25
<PAGE>   46
 
properties and assets substantially as an entirety to a trust organized as such
under the laws of any State; provided, that (i) such successor entity either (a)
expressly assumes all of the obligations of such Issuer with respect to its
Preferred Securities or (b) substitutes for such Preferred Securities other
securities having substantially the same terms as such Preferred Securities (the
"Successor Securities") so long as the Successor Securities rank the same in
priority as such Preferred Securities with respect to distributions and payments
upon liquidation, redemption and otherwise, (ii) the Company expressly appoints
a trustee of such successor entity possessing the same powers and duties as the
Property Trustee as the holder of the related Corresponding Junior Subordinated
Debentures, (iii) the Successor Securities are listed, or any Successor
Securities will be listed upon notification of issuance, on any national
securities exchange or other organization on which such Preferred Securities are
then listed, (iv) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause such Preferred Securities
(including any Successor Securities) to be downgraded by any nationally
recognized statistical rating organization, (v) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of such Preferred
Securities (including any Successor Securities) in any material respect, (vi)
such successor entity has a purpose identical to that of such Issuer, (vii)
prior to such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease the Company has received an opinion from independent counsel
to such Issuer experienced in such matters to the effect that (a) such merger,
consolidation, amalgamation, replacement conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of such
Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease neither such Issuer nor such
successor entity will be required to register as an investment company under the
Investment Company Act and (viii) the Company or any permitted successor or
assignee owns all of the Common Securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the applicable Guarantee.
Notwithstanding the foregoing, an Issuer shall not, except with the consent of
holders of 100% in Liquidation Amount of its Preferred Securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to any other entity or
permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger, replacement, conveyance,
transfer or lease would cause such Issuer or the successor entity to be
classified as other than a grantor trust for U.S. federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENTS
 
Except as provided below and under "Description of Guarantees -- Amendments and
Assignment" and as otherwise required by law and each Trust Agreement, the
holders of the Preferred Securities will have no voting rights.
 
A Trust Agreement may be amended from time to time by the Company and the Issuer
Trustees, without the consent of the holders of the applicable Preferred
Securities (i) to cure any ambiguity, correct or supplement any provisions in
such Trust Agreement which may be inconsistent with any other provision, or to
make any other provisions with respect to matters or questions arising under
such Trust Agreement, which shall not be inconsistent with the other provisions
of such Trust Agreement, or (ii) to modify, eliminate or add to any provisions
of such Trust Agreement to such extent as shall be necessary to ensure that the
applicable Issuer will be classified for U.S. federal income tax purposes as a
grantor trust at all times that any Trust Securities of such Issuer are
outstanding or to ensure that such Issuer will not be required to register as an
"investment company" under the Investment Company Act; provided, however, that
in the case of clause (i), such action shall not adversely affect in any
material respect the interests of any holder of Trust Securities of such Issuer,
and any amendments of such Trust Agreement shall become effective when notice
thereof is given to the holders of Trust Securities of such Issuer. A Trust
Agreement
                                       26
<PAGE>   47
 
may be amended by the Issuer Trustees and the Company with (i) the consent of
holders representing not less than a majority (based upon Liquidation Amounts)
of the outstanding Trust Securities of the applicable Issuer and (ii) receipt by
the Issuer Trustees of an opinion of counsel to the effect that such amendment
or the exercise of any power granted to the Issuer Trustees in accordance with
such amendment will not affect the Issuer's status as a grantor trust for U.S.
federal income tax purposes or such Issuer's exemption from status of an
"investment company" under the Investment Company Act, provided that without the
consent of each holder of Trust Securities of such Issuer, such Trust Agreement
may not be amended to (i) change the amount or timing of any Distribution on the
Trust Securities of such Issuer or otherwise adversely affect the amount of any
Distribution required to be made in respect of such Trust Securities as of a
specified date or (ii) restrict the right of a holder of Trust Securities to
institute suit for the enforcement of any such payment on or after such date.
 
So long as any Corresponding Junior Subordinated Debentures are held by the
Property Trustee, the Issuer Trustees shall not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on the Property Trustee with
respect to such Corresponding Junior Subordinated Debentures, (ii) waive any
past default that is waiveable under Section 5.13 of the Subordinated Indenture,
(iii) exercise any right to rescind or annul a declaration that the principal of
all the Junior Subordinated Debentures shall be due and payable or (iv) consent
to any amendment, modification or termination of the Subordinated Indenture or
such Corresponding Junior Subordinated Debentures, where such consent shall be
required, without, in each case, obtaining the prior approval of the holders of
a majority in aggregate Liquidation Amount of all outstanding Preferred
Securities of the applicable Issuer; provided, however, that where a consent
under the Subordinated Indenture would require the consent of each holder of
Corresponding Junior Subordinated Debentures affected thereby, no such consent
shall be given by the Property Trustee without the prior consent of each holder
of the related Preferred Securities. The Issuer Trustees shall not revoke any
action previously authorized or approved by a vote of the related Preferred
Securities except by subsequent vote of the holders of the Preferred Securities.
The Property Trustee shall notify all holders of the related Preferred
Securities of any notice of default with respect to the Corresponding Junior
Subordinated Debentures. In addition to obtaining the foregoing approvals of the
holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Issuer Trustees shall obtain an opinion of counsel experienced in
such matters to the effect that such action shall not cause the applicable
Issuer to fail to be classified as a grantor trust for U.S. federal income tax
purposes.
 
Any required approval of holders of Preferred Securities may be given at a
meeting of holders of Preferred Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be given
to each holder of record of Preferred Securities in the manner set forth in the
applicable Trust Agreement.
 
No vote or consent of the holders of Preferred Securities will be required for
an Issuer to redeem and cancel its Preferred Securities in accordance with the
applicable Trust Agreement.
 
Notwithstanding that holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities that are owned by the Company, the Issuer Trustees or any affiliate
of the Company or any Issuer Trustees, shall, for purposes of such vote or
consent, be treated as if they were not outstanding.
 
GLOBAL PREFERRED SECURITIES
 
The Preferred Securities of an Issuer may be issued in whole or in part in the
form of one or more Global Preferred Securities that will be deposited with, or
on behalf of, the Depositary identified in
 
                                       27
<PAGE>   48
 
the Prospectus Supplement relating to such Preferred Securities. Unless
otherwise indicated in the applicable Prospectus Supplement for such Preferred
Securities, the Depositary will be The Depository Trust Company ("DTC"). Global
Preferred Securities may be issued only in fully registered form and in either
temporary or permanent form. Unless and until it is exchanged in whole or in
part for the individual Preferred Securities represented thereby, a Global
Preferred Security may not be transferred except as a whole by the Depositary
for such Global Preferred Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any nominee to a successor Depositary or any
nominee of such successor.
 
While the specific terms of the depositary arrangement with respect to the
Preferred Securities of an Issuer (if other than as described under "Book-Entry
Issuance") will be described in the Prospectus Supplement relating to such
Preferred Securities, the Company anticipates that the following provisions will
generally apply to depositary arrangements.
 
Upon the issuance of a Global Preferred Security, and the deposit of such Global
Preferred Security with or on behalf of the applicable Depositary, the
Depositary for such Global Preferred Security or its nominee will credit, on its
book-entry registration and transfer system, the respective aggregate
Liquidation Amounts of the individual Preferred Securities represented by such
Global Preferred Securities to the accounts of Participants. Such accounts shall
be designated by the dealers, underwriters or agents with respect to such
Preferred Securities or by the Company if such Preferred Securities are offered
and sold directly by the Company. Ownership of beneficial interests in a Global
Preferred Security will be limited to Participants or persons that may hold
interests through Participants. Ownership of beneficial interests in such Global
Preferred Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the applicable Depositary or its
nominee (with respect to interests of Participants) and the records of
Participants (with respect to interests of persons who hold through
Participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Preferred Security.
 
So long as the Depositary for a Global Preferred Security, or its nominee, is
the registered owner of such Global Preferred Security, such Depositary or such
nominee, as the case may be, will be considered the sole owner or holder of the
Preferred Securities represented by such Global Preferred Security for all
purposes under the applicable Trust Agreement. Except as provided below, owners
of beneficial interests in a Global Preferred Security will not be entitled to
have any of the individual Preferred Securities represented by such Global
Preferred Security registered in their names, will not receive or be entitled to
receive physical delivery of any such Preferred Securities in definitive form
and will not be considered the owners or holders thereof under the applicable
Trust Agreement.
 
Payments of Liquidation Amount, premium or Distributions in respect of
individual Preferred Securities represented by a Global Preferred Security
registered in the name of a Depositary or its nominee will be made to such
Depositary or its nominee, as the case may be, as the registered owner of the
Global Preferred Security representing such Preferred Securities. None of the
Company, the Property Trustee, any paying agent or the registrar for such
Preferred Securities will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests of the Global Preferred Security representing such Preferred
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
The Company expects that the Depositary for the Preferred Securities of an
Issuer, or its nominee, upon receipt of any payment of Liquidation Amount,
premium or Distributions in respect of a Global Preferred Security representing
any of such Preferred Securities, immediately will credit Participants' accounts
with payments in amounts proportionate to their respective beneficial interest
in the
 
                                       28
<PAGE>   49
 
aggregate Liquidation Amount of such Global Preferred Security for such
Preferred Securities as shown on the records of such Depositary or its nominee.
The Company also expects that payments by Participants to owners of beneficial
interests in such Global Preferred Security held through such Participants will
be governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in "street name". Such payments will be the responsibility of such Participants.
 
Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for the Preferred Securities of an Issuer is at any time unwilling,
unable or ineligible to continue as a depositary and a successor depositary is
not appointed by the Company within 90 days, the applicable Issuer will issue
individual Preferred Securities of such Issuer in exchange for the Global
Preferred Security representing such Preferred Securities. In addition, the
Company may at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Preferred Securities,
determine not to have any Preferred Securities of an Issuer represented by one
or more Global Preferred Securities and, in such event, the applicable Issuer
will issue individual Preferred Securities in exchange for the Global Preferred
Security or Securities representing such Preferred Securities. Further, if the
Company so specifies with respect to the Preferred Securities of an Issuer, an
owner of a beneficial interest in a Global Preferred Security representing such
Preferred Securities may, on terms acceptable to the Company, the Property
Trustee and the Depositary for such Global Preferred Security, receive
individual Preferred Securities in exchange for such beneficial interests,
subject to any limitations described in the Prospectus Supplement relating to
such Preferred Securities. In any such instance, an owner of a beneficial
interest in a Global Preferred Security will be entitled to physical delivery of
individual Preferred Securities represented by such Global Preferred Security
equal in Liquidation Amount to such beneficial interest and to have such
Preferred Securities registered in its name. Individual Preferred Securities so
issued will be issued in denominations, unless otherwise specified by the
Company, of $25 and integral multiples thereof.
 
PAYMENT AND PAYING AGENCY
 
Payments in respect of the Preferred Securities shall be made to the applicable
Depositary, which shall credit the relevant accounts at such Depositary on the
applicable Distribution Dates or, if any Issuer's Preferred Securities are not
held by a Depositary, such payments shall be made by check mailed to the address
of the holder entitled thereto as such address shall appear on the Register.
Unless otherwise specified in the applicable Prospectus Supplement, the paying
agent for the Preferred Securities shall initially be the Property Trustee and
any co-paying agent chosen by the Property Trustee and acceptable to the
Administrative Trustees and the Company. The paying agent shall be permitted to
resign as paying agent upon 30 days' written notice to the Property Trustees and
the Company. In the event that the Property Trustee shall no longer be the
paying agent, the Administrative Trustees shall appoint a successor to act as
paying agent (which shall be a bank or trust company acceptable to the
Administrative Trustees and the Company).
 
REGISTRAR AND TRANSFER AGENT
 
Unless otherwise specified in the applicable Prospectus Supplement, the Property
Trustee will act as registrar and transfer agent for the Preferred Securities.
 
Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of each Issuer, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Issuers will not be required to register or cause to be registered
the transfer of their Preferred Securities after such Preferred Securities have
been called for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
The Property Trustee, other than during the occurrence and continuance of an
Event of Default, undertakes to perform only such duties as are specifically set
forth in the Trust Agreements and, after such Event of Default, must exercise
the same degree of care and skill as a prudent person would exercise or use in
the conduct of his or her own affairs. Subject to this provision, the Property
Trustee is under no obligation to exercise any of the powers vested in it by the
Trust Agreements at the request of any holder of Preferred Securities unless it
is offered reasonable indemnity against the costs, expenses and liabilities that
might be incurred thereby. If no Event of Default has occurred and is continuing
and the Property Trustee is required to decide between alternative causes of
action, construe ambiguous provisions in a Trust Agreement or is unsure of the
application of any provision of a Trust Agreement, and the matter is not one on
which holders of Preferred Securities are entitled under such Trust Agreement to
vote, then the Property Trustee shall take such action as is directed by the
Company and if not so directed, shall take such action as it deems advisable and
in the best interests of the holders of the applicable Trust Securities and will
have no liability except for its own bad faith, negligence or willful
misconduct.
 
MISCELLANEOUS
 
The Administrative Trustees are authorized and directed to conduct the affairs
of and to operate the Issuers in such a way that no Issuer will be deemed to be
an "investment company" required to be registered under the Investment Company
Act or fail to be classified as a grantor trust for U.S. federal income tax
purposes and so that the Corresponding Junior Subordinated Debentures will be
treated as indebtedness of the Company for U.S. federal income tax purposes. In
this connection, the Company and the Administrative Trustees are authorized to
take any action, not inconsistent with applicable law, the certificate of trust
of either Issuer or either Trust Agreement, that the Company and the
Administrative Trustees determine in their discretion to be necessary or
desirable for such purposes, as long as such action does not materially
adversely affect the interests of the holders of the related Preferred
Securities.
 
Holders of the Preferred Securities have no preemptive or similar rights.
 
Neither Issuer may borrow money or issue debt or mortgage or pledge any of its
assets.
 
                           DESCRIPTION OF GUARANTEES
 
A Guarantee will be executed and delivered by the Company concurrently with the
issuance by the applicable Issuer of its Preferred Securities for the benefit of
the holders from time to time of such Preferred Securities. Wilmington Trust
Company will act as indenture trustee ("Guarantee Trustee") under each Guarantee
for the purposes of compliance with the Trust Indenture Act and each Guarantee
will be qualified as an indenture under the Trust Indenture Act. This summary of
certain provisions of the Guarantees does not purport to be complete and is
subject to, and qualified in its entirety by reference to, all of the provisions
of the applicable Guarantee Agreement, including the definitions therein of
certain terms, and the Trust Indenture Act. The form of Guarantee has been filed
as an exhibit to the Registration Statement of which this Prospectus forms a
part. References in this summary to Preferred Securities means that Issuer's
Preferred Securities to which a Guarantee relates. The Guarantee Trustee will
hold each Guarantee for the benefit of the holders of the related Issuer's
Preferred Securities.
 
GENERAL
 
The Company will irrevocably agree to pay in full on a subordinated basis, to
the extent set forth herein, the Guarantee Payments (as defined below) to the
holders of the Preferred Securities, as and when due, regardless of any defense,
right of set-off or counterclaim that the applicable Issuer may have or assert
other than the defense of payment. The following payments with respect to the
 
                                       30
<PAGE>   51
 
Preferred Securities, to the extent not paid by or on behalf of the related
Issuer (the "Guarantee Payments"), will be subject to the applicable Guarantee:
(i) any accumulated and unpaid Distributions required to be paid on such
Preferred Securities, to the extent that the applicable Issuer has funds on hand
available therefor, (ii) the Redemption Price with respect to any Preferred
Securities called for redemption to the extent that the applicable Issuer has
funds on hand available therefor, or (iii) upon a voluntary or involuntary
dissolution, winding up or liquidation of such Issuer (unless the Corresponding
Junior Subordinated Debentures are distributed to holders of such Preferred
Securities), the lesser of (a) the Liquidation Distribution and (b) the amount
of assets of such Issuer remaining available for distribution to holders of
Preferred Securities. The Company's obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by the Company to the
holders of the applicable Preferred Securities or by causing the applicable
Issuer to pay such amounts to such holders.
 
Each Guarantee will be an irrevocable guarantee on a subordinated basis of the
related Issuer's obligations under the Preferred Securities, but will apply only
to the extent that such Issuer has funds sufficient to make such payments, and
is not a guarantee of collection.
 
If the Company does not make interest payments on the Corresponding Junior
Subordinated Debentures held by an Issuer, it is expected that such Issuer will
not pay Distributions on the Preferred Securities and will not have funds
legally available therefor. Each Guarantee will rank subordinate and junior in
right of payment to all Senior Debt. See "-- Status of the Guarantees". Except
as otherwise provided in the applicable Prospectus Supplement, the Guarantees do
not limit the incurrence or issuance of other secured or unsecured debt of the
Company, including Senior Debt, whether under the Subordinated Indenture, any
other indenture that the Company may enter into in the future or otherwise. See
the Prospectus Supplement relating to any offering of Preferred Securities.
 
Through the related Guarantee, the applicable Trust Agreement, the Junior
Subordinated Debentures, the Subordinated Indenture and the related Expense
Agreement, taken together, the Company has, in effect, fully, irrevocably and
unconditionally guaranteed all of the applicable Issuer's obligations under the
Preferred Securities. No single document standing alone or operating in
conjunction with fewer than all of the other documents constitutes such
guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of the
applicable Issuer's obligations under the Preferred Securities. See
"Relationship Among the Preferred Securities, the Junior Subordinated Debentures
and the Guarantees".
 
STATUS OF THE GUARANTEES
 
Each Guarantee will constitute an unsecured obligation of the Company that will
rank (i) subordinate and junior in right of payment to all liabilities of the
Company, including all Senior Debt and the Junior Subordinated Debentures, and
(ii) pari passu (i.e. on a parity) with the other Guarantee, with the guarantee
by the Company of certain payments required to be made in respect of the
Convertible Subordinated Debentures, with the most senior preferred or
preference stock now or hereafter issued by the Company and with any guarantee
now or hereafter entered into by the Company in respect of any preferred or
preference stock of any affiliate of the Company and (iii) senior to Common
Stock and any other class or series of capital stock issued by the Company or
any of its affiliates which by its express terms ranks junior to such Guarantee
in the payment of dividends and amounts on liquidation, dissolution, and
winding-up. On the bankruptcy, liquidation or winding-up of the Company, its
obligations under each Guarantee will rank junior to all its other liabilities
and, therefore, funds may not be available for payment under the Guarantees.
 
Each Guarantee will constitute a guarantee of payment and not of collection
(i.e., the guaranteed party may institute a legal proceeding directly against
the Company to enforce its rights under the applicable Guarantee without first
instituting a legal proceeding against any other person or entity).
 
                                       31
<PAGE>   52
 
Each Guarantee will be held for the benefit of the holders of the related
Preferred Securities. Each Guarantee will not be discharged except by payment of
the Guarantee Payments in full to the extent not paid by the applicable Issuer
or upon distribution to the holders of the Preferred Securities of the
Corresponding Junior Subordinated Debentures. Neither of the Guarantees places a
limitation on the amount of additional Senior Debt that may be incurred by the
Company. The Company expects from time to time to incur additional indebtedness
constituting Senior Debt.
 
AMENDMENTS AND ASSIGNMENT
 
Except with respect to any changes which do not materially adversely affect the
rights of holders of the related Preferred Securities (in which case no vote
will be required), neither Guarantee may be amended without the prior approval
of the holders of not less than a majority of the aggregate Liquidation Amount
of the related Preferred Securities then outstanding. The manner of obtaining
any such approval will be as set forth under "Description of Preferred
Securities -- Voting Rights; Amendment of Trust Agreements". All guarantees and
agreements contained in each Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the holders of the related Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
An event of default under a Guarantee will occur upon the failure of the Company
to perform any of its payment or other obligations thereunder. The holders of
not less than a majority in aggregate Liquidation Amount of the related
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of such Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under such Guarantee.
 
Any holder of Preferred Securities may institute a legal proceeding directly
against the Company to enforce its rights under such Guarantee without first
instituting a legal proceeding against the Issuer, the Guarantee Trustee or any
other person or entity.
 
The Company, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not the Company is in compliance with all
the conditions and covenants applicable to it under each Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
The Guarantee Trustee, other than during the occurrence and continuance of a
default by the Company in performance of a Guarantee, undertakes to perform only
such duties as are specifically set forth in the applicable Guarantee and, after
default with respect to a Guarantee, must exercise the same degree of care and
skill as a prudent person would exercise or use in the conduct of his or her own
affairs. Subject to this provision, the Guarantee Trustee is under no obligation
to exercise any of the powers vested in it by a Guarantee at the request of any
holder of the related Preferred Securities unless it is offered reasonable
indemnity against the costs, expenses and liabilities that might be incurred
thereby.
 
TERMINATION OF THE GUARANTEES
 
A Guarantee will terminate and be of no further force and effect upon full
payment of the Redemption Price of the related Preferred Securities, upon full
payment of the amounts payable upon liquidation of the related Issuer or upon
distribution of Corresponding Junior Subordinated Debentures to the holders of
the related Preferred Securities. A Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any holder of the related
Preferred Securities must restore payment of any sums paid under such Preferred
Securities or such Guarantee.
 
                                       32
<PAGE>   53
 
GOVERNING LAW
 
Each Guarantee will be governed by and construed in accordance with the laws of
the State of New York.
 
THE EXPENSE AGREEMENTS
 
Pursuant to the Expense Agreement entered into by the Company under each Trust
Agreement (each, an "Expense Agreement"), the Company will irrevocably and
unconditionally guarantee to each person or entity to whom the applicable Issuer
becomes indebted or liable, the full payment of any costs, expenses or
liabilities of such Issuer, other than obligations of such Issuer to pay to the
holders of any Preferred Securities or other similar interests in such Issuer
the amounts due such holders pursuant to the terms of the Preferred Securities
or such other similar interests, as the case may be.
 
                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
      THE CORRESPONDING JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEES
 
As long as payments of interest and other payments are made when due on each
series of Corresponding Junior Subordinated Debentures, such payments will be
sufficient to cover Distributions and other payments due on the corresponding
Preferred Securities, primarily because (i) the aggregate principal amount of
each series of Corresponding Junior Subordinated Debentures will be equal to the
sum of the aggregate stated Liquidation Amount of the corresponding Preferred
Securities and corresponding Common Securities; (ii) the interest rate and
interest and other payment dates on each series of Corresponding Junior
Subordinated Debentures will match the Distribution rate and Distribution and
other payment dates for the corresponding Preferred Securities; (iii) the
Company shall pay all and any costs, expenses and liabilities of the applicable
Issuer except such Issuer's obligations to holders of its Preferred Securities
under such Preferred Securities; and (iv) each Trust Agreement further provides
that the applicable Issuer will not engage in any activity that is not
consistent with the limited purposes of such Issuer.
 
Payments of Distributions and other amounts due on the Preferred Securities (to
the extent the applicable Issuer has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Company as and to the extent
set forth under "Description of Guarantees". Taken together, the Company's
obligations under a series of Junior Subordinated Debentures, the Subordinated
Indenture, the related Trust Agreement, the related Expense Agreement and the
related Guarantee have the effect of providing a full, irrevocable and
unconditional guarantee of payments of Distributions and other amounts due on
the related Preferred Securities. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such
guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of the
applicable Issuer's obligations under the related Preferred Securities. If and
to the extent that the Company does not make payments on any series of
Corresponding Junior Subordinated Debentures, the applicable Issuer will not pay
Distributions or other amounts due on its Preferred Securities. The Guarantees
do not cover payment of Distributions when the related Issuer does not have
sufficient funds to pay such Distributions. In such event, the remedy of a
holder of a series of Preferred Securities is to institute a legal proceeding
directly against the Company for enforcement of payment of such Distributions to
such holder.
 
Notwithstanding anything to the contrary in the Subordinated Indenture, the
Company has the right to set-off any payment it is otherwise required to make
thereunder with and to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a payment under the related
Guarantee.
 
                                       33
<PAGE>   54
 
A holder of any related Preferred Security may institute a legal proceeding
directly against the Company to enforce its rights under the related Guarantee
without first instituting a legal proceeding against the Guarantee Trustee, the
related Issuer or any other person or entity.
 
Each Issuer's Preferred Securities evidence preferred undivided beneficial
interests in the assets of such Issuer, and each Issuer exists for the sole
purpose of issuing its Preferred Securities and Common Securities and investing
the proceeds thereof in Corresponding Junior Subordinated Debentures. A
principal difference between the rights of a holder of a Preferred Security and
a holder of a Corresponding Junior Subordinated Debenture is that a holder of a
Corresponding Junior Subordinated Debenture will accrue, and (subject to the
permissible extension of the interest period) is entitled to receive, interest
on the principal amount of Corresponding Junior Subordinated Debentures held,
while a holder of Preferred Securities is only entitled to receive Distributions
if and to the extent the applicable Issuer has funds available for the payment
of such Distributions.
 
Upon any voluntary or involuntary dissolution of an Issuer involving the
liquidation of the Corresponding Junior Subordinated Debentures, the holders of
Preferred Securities of such Issuer will be entitled to receive, out of assets
held by such Issuer, the Liquidation Distribution in cash. See "Description of
Preferred Securities -- Liquidation Distribution Upon Termination". Upon any
voluntary or involuntary liquidation or bankruptcy of the Company, the Property
Trustee, as holder of the Corresponding Junior Subordinated Debentures, would be
a subordinated creditor of the Company, subordinated in right of payment to all
Senior Debt, but entitled to receive payment in full of principal and interest,
before any stockholders of the Company receive payments or distributions. Since
the Company is the guarantor under each Guarantee and has agreed to pay for all
costs, expenses and liabilities of each Issuer (other than such Issuer's
obligations to the holders of its Preferred Securities), the positions of a
holder of such Preferred Securities and a holder of such Corresponding Junior
Subordinated Debentures relative to other creditors and to stockholders of the
Company in the event of liquidation or bankruptcy of the Company would be
substantially the same.
 
A default or event of default under any Senior Debt would not constitute a
default or Debenture Event of Default under the Subordinated Indenture. However,
in the event of payment defaults under, or acceleration of, Senior Debt, the
subordination provisions of the Subordinated Indenture provide that no payments
may be made in respect of the Corresponding Junior Subordinated Debentures until
such Senior Debt has been paid in full or any payment default thereunder has
been cured or waived. Failure to make required payments on any series of
Corresponding Junior Subordinated Debentures would constitute a Debenture Event
of Default under the Subordinated Indenture.
 
                         DESCRIPTION OF DEBT SECURITIES

If any index is used to determine the amount of payments of principal of,
premium, if any, or interest, if any, on any series of Debt Securities, material
U.S. federal income tax, accounting and other considerations applicable thereto
will be described in the Applicable Prospectus Supplement.
 
BOOK ENTRY DEBT SECURITIES
 
The following description of Book Entry Securities will apply to any series of
Debt Securities except as otherwise provided in the Prospectus Supplement
relating thereto.
 
The Debt Securities of a series may be issued in the form of one or more Book
Entry Securities that will be deposited with or on behalf of a Depositary, which
will be a clearing agent registered under the Exchange Act. Book Entry
Securities will be registered in the name of the Depositary or a nominee of the
Depositary, will be deposited with such Depositary or nominee or a custodian
therefor and will bear a legend regarding the restrictions on exchanges and
registration of transfer thereof and any such other matters as may be provided
for pursuant to the Indenture. Unless and until it is exchanged in whole or in
part for Debt Securities in definitive certificated form, a Book Entry Security
may not be transferred or exchanged except as a whole by the Depositary for such
Book Entry Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such
Depositary or any such nominee to a successor Depositary for such series or a
nominee of such successor Depositary, or except in the circumstances described
in the Applicable Prospectus Supplement. (Section 305)
 
Upon the issuance of any Book Entry Security, and the deposit of such Book Entry
Security with or on behalf of the Depositary for such Book Entry Security, the
Depositary will credit on its book-entry registration and transfer system the
respective principal amounts of the Debt Securities represented by such Book
Entry Security to the accounts of institutions ("Participants") that have
accounts with the Depositary. The accounts to be credited will be designated by
the underwriters or agents engaging in the distribution of such Debt Securities
or by the Company, if such Debt Securities are offered and sold directly by the
Company. Ownership of beneficial interests in a Book Entry Security will be
limited to Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in a Book Entry Security will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by the Depositary for such Book Entry Security or by its nominee. Ownership of
beneficial interests in such Book Entry Security by persons who hold through
Participants will be shown on, and the transfer of such beneficial interests
within such Participants will be effected only through, records maintained by
such Participants. The laws of some jurisdictions require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such laws may impair the ability to transfer beneficial interests in such
a Book Entry Security.
 
So long as the Depositary for a Book Entry Security, or its nominee, is the
owner of such Book Entry Security, such Depositary or such nominee, as the case
may be, will be considered the sole owner or holder of the Debt Security
represented by such Book Entry Security for all purposes under the Indenture.
Accordingly, each person owning a beneficial interest in such Book Entry
Security must rely on the procedures of the Depositary and, if such person is
not a Participant, on the procedures of the Participant through which such
person owns its interest, to exercise any rights of a holder under such
Indenture. The Company understands that under existing industry practices, if it
requests any action of holders or if an owner of a beneficial interest in a Book
Entry Security desires to give or take any instruction or action which a holder
is entitled to give or take under the Indenture, the Depositary would authorize
the Participants holding the relevant beneficial interests to give or take such
instruction or action, and such Participants would authorize beneficial owners
owning through such Participants to give or take such instruction or action or
would otherwise act upon the instructions of beneficial owners holding through
them.
 
Unless otherwise specified in the Applicable Prospectus Supplement, payments
with respect to principal, premium, if any, and interest, if any, on the Debt
Securities represented by a Book Entry
 
                                       37
<PAGE>   58
 
Security registered in the name of the Depositary or its nominee will be made to
such Depositary or its nominee, as the case may be, as the registered owner of
such Book Entry Security. The Company expects that the Depositary for any Debt
Securities represented by a Book Entry Security, upon receipt of any payment of
principal or interest in respect of such Book Entry Security, will credit
immediately Participants' accounts with payments in amounts proportionate to
their respective beneficial interests in the Book Entry Security as shown on the
records of the Depositary. The Company also expects that payments by
Participants to owners of beneficial interests in such Book Entry Security held
through such Participants will be governed by standing instructions and
customary practices, as is now the case with securities in bearer form held for
the accounts of customers or registered in "street name", and will be the
responsibility of such Participants. None of the Company, the Trustee or any
agent of the Company or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial interests in any Book Entry Security, or for maintaining, supervising
or reviewing any records relating to such beneficial interests.
 
A Book Entry Security shall be exchangeable for Debt Securities in certificated
registered form, of like tenor and of an equal aggregate principal amount, only
if (a) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Book Entry Security or if at any time the
Depositary ceases to be a clearing agency registered under the Exchange Act, (b)
the Company in its sole discretion determines that such Book Entry Security
shall be exchangeable for Debt Securities in certificated registered form or (c)
there shall have occurred and be continuing an Event of Default with respect to
the Debt Securities. Any Book Entry Security that is exchangeable pursuant to
the preceding sentence shall be exchangeable for Debt Securities registered in
the name or names of such person or persons as the Depositary shall instruct the
Trustee. It is expected that such instructions may be based upon directions
received by the Depositary from its participants with respect to ownership of
beneficial interests in such Book Entry Security.
 
CERTAIN COVENANTS OF THE COMPANY
 
  Restrictions on Secured Debt
 
If subsequent to the date of the initial issuance of the Debt Securities of any
series, the Company or any Subsidiary shall incur, issue, assume or guarantee
any Debt secured by a Mortgage on any Principal Property owned by the Company or
any Restricted Subsidiary or on any shares of stock or Debt of any Restricted
Subsidiary, the Company will secure, or cause such Subsidiary to secure, such
Debt Securities equally and ratably with (or prior to) such secured Debt, unless
after giving effect thereto the aggregate amount of all such Debt so secured
together with all Attributable Debt in respect of sale and leaseback
transactions involving Principal Properties owned by the Company or a Restricted
Subsidiary and otherwise prohibited by the Indenture would not exceed 10% of the
Consolidated Net Tangible Assets. This restriction will not apply to, and
therefore the following shall be excluded in computing secured Debt for the
purpose of such restriction: Debt secured by (a) Mortgages on property of, or on
any shares of stock or Debt of, any corporation existing at the time such
corporation becomes a Restricted Subsidiary, (b) Mortgages in favor of the
Company or any Restricted Subsidiary, (c) Mortgages in favor of the United
States of America, or any agency, department or other instrumentality thereof,
to secure progress, advance or other payments pursuant to any contract or
provision of any statute, (d) Mortgages on property, shares of stock or Debt
existing at the time of acquisition thereof (including acquisition through
merger or consolidation) and purchase money Mortgages and construction cost
Mortgages (including those incurred within 120 days following the purchase or
completion of the property in question) and (e) any extension, renewal or
replacement of any Mortgage referred to in the foregoing clauses (a) through (d)
inclusive. The Indenture will not restrict the incurring of unsecured Debt by
the Company or its Subsidiaries.
 
                                       38
<PAGE>   59
 
  Restrictions on Sales and Leasebacks
 
Neither the Company nor any Restricted Subsidiary may enter into any sale and
leaseback transaction involving any Principal Property owned by the Company or
any Restricted Subsidiary, the acquisition of which, or completion of
construction and commencement of full operation of which, has occurred more than
120 days prior to such sale and leaseback transaction, unless (a) the Company or
such Restricted Subsidiary could create Debt secured by a Mortgage on such
property in accordance with the immediately preceding paragraph in an amount
equal to the Attributable Debt with respect to the sale and leaseback
transaction without equally and ratably securing the Outstanding Debt Securities
or (b) the Company, within 120 days after the sale or transfer of such property,
applies to the retirement of its Funded Debt an amount equal to the greater of
(i) the net proceeds of the sale of the Principal Property sold and leased back
pursuant to such arrangement or (ii) the fair market value of the Principal
Property so sold and leased back, subject to credits for certain voluntary
retirements of Funded Debt. This restriction will not apply to any sale and
leaseback transaction (a) between the Company and a Restricted Subsidiary or
between Restricted Subsidiaries or (b) involving a lease for a period of three
years or less.
 
Unless otherwise indicated in the Applicable Prospectus Supplement, the
Indenture does not contain covenants specifically designed to protect holders of
Debt Securities in the event of a highly leveraged transaction, restructuring,
change in control, merger or similar transaction involving the Company that may
adversely affect holders of Debt Securities.
 
EVENTS OF DEFAULT
 
Any one of the following events will constitute an Event of Default under the
Indenture with respect to Debt Securities of any series: (a) failure to pay any
interest on any Debt Security of that series when due, continued for 30 days;
(b) failure to pay principal of or any premium on any Debt Security of that
series when due; (c) failure to deposit any sinking fund payment, when due, in
respect of any Debt Security of that series; (d) failure to perform, or breach
of, any covenant or warranty of the Company in the Indenture with respect to
Debt Securities of that series continued for 60 days after written notice as
provided in the Indenture; (e) certain events of bankruptcy, insolvency or
reorganization of the Company; or (f) any other Event of Default provided with
respect to Debt Securities of that series. (Section 501)
 
If any Event of Default with respect to the Debt Securities of any series at the
time outstanding occurs and is continuing, either the Trustee or the holders of
at least 25% in aggregate principal amount of the Outstanding Debt Securities of
that series may declare the principal amount (or, if the Debt Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms thereof) of all the Debt Securities of
that series to be due and payable immediately. At any time after a declaration
of acceleration with respect to Debt Securities of any series has been made, but
before a judgment or decree based on acceleration has been obtained, the holders
of a majority in aggregate principal amount of Outstanding Debt Securities of
that series may, under certain circumstances, rescind and annul such
acceleration. (Section 502)
 
Reference is made to the Applicable Prospectus Supplement relating to any series
of Offered Debt Securities that are Original Issue Discount Securities for the
particular provisions relating to acceleration of the Stated Maturity of a
portion of the principal amount of such series of Original Issue Discount Debt
Securities upon the occurrence of an Event of Default and the continuation
thereof.
 
The Indenture provides that, subject to the duty of the Trustee during default
to act with the required standard of care, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the holders of Debt Securities, unless such
holders shall have offered to the Trustee reasonable indemnity. (Section 603)
Subject to such provisions for the indemnification of the Trustee and to certain
other conditions, the holders of a
                                       39
<PAGE>   60
 
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, with respect to the Debt Securities of that
series. (Section 512)
 
No holder of any series of Debt Securities will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such holder shall have previously given to the Trustee written notice of a
continuing Event of Default and unless the holders of at least 25% in principal
amount of the Outstanding Debt Securities of that series shall have made written
request, and offered reasonable indemnity, to the Trustee to institute such
proceeding as trustee, and the Trustee shall not have received from the holders
of a majority in aggregate principal amount of the Outstanding Debt Securities
of that series a direction inconsistent with such request and shall have failed
to institute such proceeding within 60 days. (Section 507) However, such
limitations do not apply to a suit instituted by a holder of a Debt Security for
enforcement of payment of the principal of and premium, if any, or interest on
such Debt Security on or after the respective due dates expressed in such Debt
Security. (Section 508)
 
The Company is required to furnish to the Trustee annually a statement as to the
performance by the Company of certain of its obligations under the Indenture and
as to any default in such performance. (Section 1004)
 
MODIFICATION AND WAIVER
 
Modifications and amendments of the Indenture may be made by the Company and the
Trustee without the consent of the holders of any of the Debt Securities in
order (i) to evidence the succession of another entity to the Company and the
assumption of the covenants and obligations of the Company under the Debt
Securities and the Indenture by such successor to the Company; (ii) to add to
the covenants of the Company for the benefit of the holders of all or any series
of Debt Securities or surrender any right or power conferred on the Company by
the Indenture; (iii) to add additional Events of Default with respect to any
series of Debt Securities; (iv) to add to or change any provisions to such
extent as necessary to facilitate the issuance of Debt Securities in bearer form
or to facilitate the issuance of Book Entry Securities; (v) to add to, change or
eliminate any provision affecting only Debt Securities not yet issued; (vi) to
secure the Debt Securities; (vii) to establish the form or terms of Debt
Securities of any series; (viii) to evidence and provide for successor Trustees
or to add or change any provisions to such extent as necessary to provide for or
facilitate the appointment of a separate Trustee or Trustees for specific series
of Debt Securities; (ix) to permit payment in respect of Debt Securities in
bearer form in the United States to the extent allowed by law; (x) to cure any
ambiguity, to correct or supplement any mistaken or inconsistent provisions or
to make any other provisions with respect to matters or questions arising under
the Indenture, provided that any such action (other than in respect of a
mistaken provision) does not adversely affect in any material respect the
interests of any holder of Debt Securities of any series then outstanding.
(Section 901)
 
Modifications and amendments of the Indenture also may be made by the Company
and the Trustee with the consent of the holders of not less than a majority in
aggregate principal amount of the Outstanding Debt Securities of each series
issued under the Indenture and affected by the modification or amendments;
provided, however, that no such modification or amendment may, without the
consent of the Holders of all Debt Securities affected thereby, (i) change the
Stated Maturity of the principal amount of, or any installment of principal of
or interest on, any Debt Security; (ii) reduce the principal amount of, or the
premium, if any, or (except as otherwise provided in the Applicable Prospectus
Supplement) interest on any Debt Security (including in the case of an Original
Issue Discount Security the amount payable upon acceleration of the maturity
thereof); (iii) change the place or currency of payment of principal of,
premium, if any, or interest on any Debt Security; (iv) impair the right to
institute suit for the enforcement of any payment on any Debt Security on or
after the Stated Maturity thereof (or in the case of redemption, on or after
                                       40
<PAGE>   61
 
the Redemption Date); or (v) reduce the percentage in principal amount of
Outstanding Debt Securities of any series, the consent of whose holders is
required for modification or amendment of the Indenture or for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults. (Section 902)
 
The holders of at least a majority in aggregate principal amount of the
Outstanding Debt Securities of any series may, on behalf of all holders of Debt
Securities of that series, waive compliance by the Company with certain
restrictive provisions of the Indenture. (Section 1010) The holders of not less
than a majority in aggregate principal amount of the Outstanding Debt Securities
of any series may, on behalf of all holders of Debt Securities of that series,
waive any past default under the Indenture, except a default in the payment of
principal, premium or interest or in respect of a covenant or provision of the
Indenture that cannot be modified or amended without the consent of the holder
of each Outstanding Debt Security of such series affected thereby. (Section 513)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
The Company may not consolidate with or merge with or into any other entity or
transfer or lease its assets substantially as an entirety to any entity, unless
(i) either the Company is the continuing corporation, or any successor or
purchaser is a corporation, partnership or trust organized under the laws of the
United States of America, any State thereof or the District of Columbia, and any
such successor or purchaser expressly assumes the Company's obligations on the
Debt Securities under a supplemental indenture, (ii) immediately after giving
effect to the transaction, no Event of Default, and no event which, after notice
or lapse of time or both, would become an Event of Default, shall have occurred
and be continuing, (iii) if properties or assets of the Company become subject
to a Mortgage not permitted by the Indenture, the Company or such successor
entity, as the case may be, takes such steps as shall be necessary effectively
to secure the Debt Securities equally and ratably with (or prior to) all Debt
secured thereby, and (iv) if a supplemental indenture is to be executed in
connection with such consolidation, merger, transfer or lease, the Company has
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel
stating compliance with these provisions. (Section 801)
 
DEFEASANCE OF OFFERED DEBT SECURITIES OR CERTAIN COVENANTS IN CERTAIN
CIRCUMSTANCES
 
  Defeasance and Discharge
 
The Indenture provides that the terms of any series of Debt Securities may
provide that the Company, at the Company's option, will be discharged from any
and all obligations in respect of the Debt Securities of such series (except for
certain obligations to register the transfer or exchange of Debt Securities of
such series, to replace stolen, lost or mutilated Debt Securities of such
series, to maintain paying agencies and to hold moneys for payment in trust)
upon the deposit with the Trustee, in trust, of money and/or U.S. Government
Obligations which, through the payment of interest and principal thereof in
accordance with their terms, will provide money in an amount sufficient to pay
any installment of principal (and premium, if any) and interest on, and any
mandatory sinking fund payments in respect of, the Debt Securities of such
series on the stated maturity of such payments in accordance with the terms of
the Indenture and such Debt Securities. Such discharge may only occur if, among
other things, the Company has delivered to the Trustee an opinion of counsel to
the effect that the Company has received from, or there has been published by,
the United States Internal Revenue Service a ruling, or there has been a change
in tax law, in either case to the effect that such discharge will not be deemed,
or result in, a taxable event with respect to holders of the Debt Securities of
such series. (Sections 1302 and 1304)
 
  Defeasance of Certain Covenants
 
The Indenture provides that the terms of any series of Debt Securities may
provide the Company with the option to omit to comply with certain restrictive
covenants described in this Prospectus
 
                                       41
<PAGE>   62
 
under "-- Certain Covenants of the Company -- Restrictions on Secured Debt",
"-- Certain Covenants of the Company -- Restrictions on Sales and Leasebacks"
and "-- Consolidation, Merger and Sale of Assets". The Company, in order to
exercise such option, will be required to deposit with the Trustee money and/or
U.S. Government Obligations which, through the payment of interest and principal
thereof in accordance with their terms, will provide money in an amount
sufficient to pay principal (and premium, if any) and interest on, and any
mandatory sinking fund payments in respect of, the Debt Securities of such
series on the stated maturity of such payments in accordance with the terms of
the Indenture and such Debt Securities. The Company will also be required to
deliver to the Trustee an opinion of counsel to the effect that the deposit and
related covenant defeasance will not cause the holders of the Debt Securities of
such series to recognize income, gain or loss for federal income tax purposes.
(Sections 1303 and 1304)
 
In the event the Company exercises this option and the Debt Securities of such
series are declared due and payable because of the occurrence of any Event of
Default, the amount of money and U.S. Government Obligations on deposit with the
Trustee will be sufficient to pay amounts due on the Debt Securities of such
series at the time of their stated maturity but may not be sufficient to pay
amounts due on the Debt Securities of such series at the time of the
acceleration resulting from such Event of Default. However, the Company shall
remain liable for such payments.
 
The Applicable Prospectus Supplement will state if any defeasance provision will
apply to the Offered Debt Securities.
 
CONCERNING THE TRUSTEE
 
The Bank of New York, a New York banking corporation, is the Trustee under the
Indenture and is also trustee under several other indentures with the Company.
The Company maintains banking and other business relationships in the ordinary
course of business with The Bank of New York. Pursuant to the provisions of the
TIA, upon the occurrence of certain events, The Bank of New York may be deemed
to have a conflicting interest, by virtue of its acting as the Trustee under the
Indenture, the several other indentures and its other business relationships
with the Company, thereby requiring it to resign and be replaced by a successor
trustee under any or all of the Indenture or the several other indentures.
 
The Trustee may resign at any time or may be removed by the holders of at least
a majority in aggregate principal amount of the Outstanding Debt Securities. If
the Trustee resigns, is removed or becomes incapable of acting as Trustee or if
a vacancy occurs in the office of the Trustee for any cause, a successor Trustee

COMMON STOCK
 
Each holder of Common Stock is entitled to one vote for every share standing in
his or her name on the books of the Company. The Common Stock does not have
cumulative voting rights for the election of directors, which means that holders
of more than 50% of the shares voting for the election of directors can elect
100% of the directors if they choose to do so, and, in such event, the holders
of the remaining shares voting for the election of directors will not be able to
elect any person or persons to the Board of Directors.
 
Subject to the limitations contained in the Company's debt instruments and after
provision for the payment of dividends on any series of Preferred Stock which
might be issued and which has a preference with respect to the payment of
dividends, holders of Common Stock are entitled to receive such dividends as may
be declared by the Board of Directors of the Company.
 
The Common Stock has no conversion rights and is not redeemable. No holder of
Common Stock has any preemptive right to subscribe for any stock or other
securities of the Company which may be issued.
 
In the event of dissolution, liquidation or winding up of the Company, or upon
any distribution of its assets, the holders of Common Stock are entitled to
receive a pro rata portion of all of the assets available for distribution to
stockholders, subject to any preferential right which may be accorded to any
series of Preferred Stock which might be issued.
 
The Common Stock is listed on the New York Stock Exchange. The outstanding
shares of Common Stock are validly issued, fully paid and non-assessable.
 
PREFERRED STOCK
 
The Board of Directors of the Company has the authority, without further action
by stockholders, to determine the principal rights, preferences and privileges
of any unissued Preferred Stock. Provisions may be included in the shares of
Preferred Stock, such as extraordinary voting, dividend, redemption or
conversion rights, which could discourage an unsolicited tender offer or
takeover proposal.
 
The particular terms of any series of Preferred Stock offered hereby will be set
forth in the Prospectus Supplement relating thereto. The rights, preferences,
privileges and restrictions, including dividend rights, voting rights, terms of
redemption, retirement and sinking fund provisions and liquidation preferences,
if any, of the Preferred Stock of each series will be fixed or designated
pursuant to a certificate of designation adopted by the Board of Directors of
the Company or a duly authorized committee thereof. The terms, if any, on which
shares of any series of Preferred Stock are convertible or exchangeable into
Common Stock will also be set forth in the Prospectus Supplement relating
thereto. Such terms may include provisions for conversion or exchange, either
mandatory, at the option of the holder, or at the option of the Company, in
which case the number of shares of Common Stock to be received by the holders of
Preferred Stock would be calculated as of a time and in the manner stated in the
applicable Prospectus Supplement. The description of the terms of a particular
series of Preferred Stock that will be set forth in the applicable Prospectus
Supplement does not purport to be complete and is qualified in its entirety by
reference to the certificate of designation relating to such series.
 
SERIES A PREFERRED STOCK
 
Out of the authorized Preferred Stock, the Company has designated 750,000 shares
of Series A Participating Preferred Stock ("Series A Preferred Stock"), the
terms of which are summarized below. Each outstanding share of Common Stock
includes a right, which expires December 30, 2006, to purchase one one-hundredth
of a share of Series A Preferred Stock ("1996 Preferred Share Purchase Rights"),
which Rights are listed on the New York Stock Exchange and the terms of which
are summarized below under "1996 Preferred Share Purchase Rights".
                                       43
<PAGE>   64
 
  Dividends
 
Holders of shares of Series A Preferred Stock are entitled to receive, when, as
and if declared by the Board of Directors out of funds legally available for the
purpose, dividends, payable in cash quarterly in arrears on January 1, April 1,
July 1 and October 1 of each year (each, a "Quarterly Dividend Payment Date"),
at an annual rate per share of the greater of (i) $10.00 or (ii) 100 times the
aggregate per share amount of all cash and non-cash dividends or other
distributions (other than dividends payable in Common Stock or subdivisions of
outstanding shares of Common Stock) declared on the Common Stock since the last
Quarterly Dividend Payment Date. Accrued but unpaid dividends accumulate but do
not bear interest.
 
The Series A Preferred Stock will be junior as to dividends to any series or
class of Preferred Stock (or any similar stock) that ranks senior as to
dividends to the Series A Preferred Stock. The Series A Preferred Stock has
priority as to dividends over the Common Stock and any other series or class of
the Company's stock thereafter issued that ranks junior as to dividends to the
Series A Preferred Stock. If dividends or distributions payable on the Series A
Preferred Stock are in arrears, the Company (i) may not declare or pay dividends
or other distributions on the Common Stock (or any other stock of the Company
that ranks junior to the Series A Preferred Stock) and (ii) is restricted in its
declaration and payment of dividends or other distributions on any stock of the
Company that ranks on a parity with the Series A Preferred Stock except for
dividends paid ratably in accordance with the respective preferential amounts
payable on the Series A Preferred Stock and all such parity stock.
 
  Liquidation Rights
 
In the case of the voluntary or involuntary liquidation, dissolution or
winding-up of the Company, holders of shares of Series A Preferred Stock are
entitled to receive the liquidation preference of the higher of (i) $100.00 per
share, plus an amount equal to the accrued and unpaid dividends to the payment
date, or (ii) 100 times the aggregate per share amount to be distributed to
holders of shares of Common Stock, before any payment or distribution is made to
the holders of shares of Common Stock (or any other stock of the Company that
ranks junior to the Series A Preferred Stock). The holders of shares of Series A
Preferred Stock and of any other stock of the Company that ranks on a parity
with the Series A Preferred Stock are entitled to share ratably, in accordance
with the respective preferential amounts payable on such stock, in any
distribution that is not sufficient to pay in full the aggregate of the amounts
payable thereon.
 
  Consolidation and Merger Rights
 
In case the Company enters into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are changed into or exchanged
for other stock or securities, cash and/or any other property, each share of
Series A Preferred Stock at the same time will be similarly changed into or
exchanged for an amount per share equal to 100 times the aggregate amount of
stock or securities, cash and/or any other property into which or for which each
share of Common Stock is changed or exchanged.
 
  Limitation on Share Repurchase
 
If dividends or distributions payable on the Series A Preferred Stock are in
arrears, the Company may not redeem, purchase or otherwise acquire for
consideration (i) any stock of the Company that ranks on a parity with the
Series A Preferred Stock, except in exchange for shares of any stock of the
Company ranking junior to the Series A Preferred Stock or (ii) any shares of
Series A Preferred Stock or any stock of the Company that ranks on a parity with
the Series A Preferred Stock, except through a purchase offer made in writing or
by publication to all holders of such shares on terms that the Board of
Directors of the Company determines will result in fair and equitable treatment
among the respective series or classes of shares.
 
                                       44
<PAGE>   65
 
  Voting Rights
 
Each share of Series A Preferred Stock entitles the holder thereof to 100 votes
on all matters submitted to a vote of the Company's stockholders, and the
holders of the shares of Series A Preferred Stock and the holders of shares of
Common Stock and any other capital stock of the Company having general voting
rights will vote together as one class on all matters submitted to a vote of the
Company's stockholders.
 
If, at the time of any annual stockholders' meeting for the election of
directors, the equivalent of at least six quarterly dividends payable on any
shares of Series A Preferred Stock are in default, the number of members of the
Company's Board of Directors will be increased by two, and the holders of the
Series A Preferred Stock, voting separately as a class, will be entitled at such
meeting (and each subsequent annual stockholders' meeting) to elect such two
additional directors. Such voting rights will terminate when all such dividends
in arrears have been paid or declared and set apart for payment. Upon the
termination of such voting rights, the terms of office of all directors so
elected will terminate immediately and the number of members of the Company's
Board of Directors will be reduced by two.
 
  Other Features
 
The shares of Series A Preferred Stock are not redeemable. Unless otherwise
provided in the Company's Restated Certificate of Incorporation or the
designation of a subsequent series of Preferred Stock, the Series A Preferred
Stock will rank junior to all of the Company's other series of Preferred Stock
as to the payment of dividends and the distribution of assets on liquidation,
dissolution or winding-up, and senior to the Common Stock. Series A Preferred
Stock may be issued in fractions of a share (in one onehundredths ( 1/100) of a
share and integral multiples thereof).
 
1996 PREFERRED SHARE PURCHASE RIGHTS
 
Under a Rights Agreement, dated as of December 12, 1996 (the "1996 Rights
Agreement"), between the Company and The Chase Manhattan Bank, as Rights Agent,
each outstanding share of Common Stock is coupled with a 1996 Preferred Share
Purchase Right. Each right entitles the holder to buy from the Company one
one-hundredth of a share of Series A Preferred Stock at a price of $190.
 
The 1996 Preferred Share Purchase Rights become exercisable and detach from the
Common Stock ten business days after a person or group acquires, or announces a
tender offer for, 15% or more of the Company's outstanding shares of Common
Stock. The rights will expire on December 30, 2006, unless redeemed earlier by
the Company. The rights are redeemable by the Company at one cent each at any
time prior to public announcement or notice to the Company that an acquiring
person or group has purchased 15% or more of the Company's outstanding Common
Stock (an "Acquisition Event"). At any time after an Acquisition Event and prior
to the acquisition by such person or group of 50% or more of the outstanding
Common Stock, the Board of Directors of the Company may exchange one share of
Common Stock for each right outstanding, other than the rights held by the
acquiring person or group. At any time after an Acquisition Event and the rights
become exercisable, each right, other than rights held by the acquiring person
or group, would entitle its holder to buy Common Stock of the Company having a
market value of twice the exercise price of the right or, if the Company is
subsequently acquired in a merger or other business combination, such shares of
the acquiring or surviving company. Until the 1996 Preferred Share Purchase
Rights detach from the Common Stock (or the earlier termination or redemption of
the 1996 Preferred Share Purchase Rights), an additional 1996 Preferred Share
Purchase Right will be issued with every share of newly issued Common Stock.

DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. In general, this statute prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person becomes an interested stockholder, unless the
business combination is approved in a prescribed manner. An "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within the prior three years did own) 15% or more of the corporation's voting
stock.
 
In addition to Section 203 of the General Corporation Law of Delaware and the
Preferred Share Purchase Rights, the Charter contains several provisions that
may discourage certain transactions involving an actual or threatened change of
control of the Company.
 
For example, the Charter requires that certain business combinations and other
combinations involving the Company and a holder of 10% or more of its voting
securities be approved by at least 66 2/3% of all shares having voting rights.
 
The foregoing provisions of the General Corporation Law of Delaware and the
Charter are intended to encourage persons seeking to acquire control of the
Company to consult first with the Board of Directors to permit negotiation of
the terms of any proposed business combination or offer. They may, however, also
have the effect of discouraging a third party from attempting to acquire control
of the Company. In addition, since these provisions are designed to discourage
accumulations of large blocks of stock by third parties who wish to gain control
of the Company, such provisions may reduce the temporary market price
fluctuations caused by such accumulations.
 
TRANSFER AGENT AND REGISTRAR
 
The primary Transfer Agent and Registrar for the Common Stock is ChaseMellon
Shareholder Services, located in New York, New York.
 
                            DESCRIPTION OF WARRANTS
 
The Company may issue Warrants, including Warrants to purchase Debt Securities
("Debt Warrants"), Preferred Stock, Common Stock or other of its securities.
Warrants may be issued independently or together with any such securities of the
Company and may be attached to or separate from such securities of the Company.
The Warrants are to be issued under warrant agreements (each a "Warrant
Agreement") to be entered into between the Company and a bank or trust company,
as warrant agent (the "Warrant Agent"), all as shall be set forth in the
Prospectus Supplement relating to Warrants being offered pursuant thereto. The
description of the terms of the Warrants that are set forth below and that will
be set forth in the applicable Prospectus Supplement do not purport to be
complete and are qualified in their entirety by reference to the Warrant
Agreement and warrant certificate relating to such Warrants.
 
DEBT WARRANTS

offered thereby, the Warrant Agreement relating to such Debt Warrants and the
warrant certificates representing such Debt Warrants, including the following:
(i) the specific designation of such Debt Warrants; (ii) the Debt Securities of
the Company for which such Debt Warrants are exercisable; (iii) the aggregate
number of such Debt Warrants; (iv) the principal amount of Debt Securities
purchasable upon exercise of each Debt Warrant, and the price or prices at which
such Debt Warrants will be issued; (v) the procedures and conditions relating to
the exercise of such Debt Warrants; (vi) the designation and terms of any
related Debt Securities of the Company with which such Debt Warrants are issued,
and the number of such Debt Warrants issued with each such Debt Security; (vii)

                                       46
<PAGE>   67
 
Company will be separately transferable; (viii) the date on which the right to
exercise such Debt Warrants shall commence, and the date on which such right
shall expire; (ix) the maximum or minimum number of such Debt Warrants which may
be exercised at any time; (x) if applicable, a discussion of material U.S.
federal income tax considerations; (xi) any other terms of such Debt Warrants
and terms, procedures and limitations relating to the exercise of such Debt
Warrants; and (xii) the terms of the securities of the Company purchasable upon
exercise of such Debt Warrants. Prior to the exercise of their Debt Warrants,
holders of Debt Warrants exercisable for Debt Securities will not have any of
the rights of holders of the Debt Securities purchasable upon such exercise and
will not be entitled to payments of principal (or premium, if any) or interest,
if any, on the Debt Securities purchasable upon such exercise.
 
OTHER WARRANTS
 
The Company may issue other Warrants. The applicable Prospectus Supplement will
describe the following terms of any such other Warrants in respect of which this
Prospectus is being delivered: (i) the title of such Warrants; (ii) the
securities (which may include Preferred Stock or Common Stock) for which such
Warrants are exercisable; (iii) the price or prices at which such Warrants will
be issued; (iv) if applicable, the designation and terms of the Preferred Stock
or Common Stock with which such Warrants are issued, and the number of such
Warrants issued with each such share of Preferred Stock or Common Stock; (v) if
applicable, the date on and after which such Warrants and the related Preferred
Stock or Common Stock will be separately transferable; (vi) if applicable, a
discussion of material U.S. federal income tax considerations; and (vii) any
other terms of such Warrants, including terms, procedures and limitations
relating to the exchange and exercise of such Warrants. The applicable
Prospectus Supplement will also set forth (a) the amount of securities called
for by such Warrants, and if applicable, the amount of Warrants outstanding, and
(b) information relating to provisions, if any, for a change in the exercise
price or the expiration date of such Warrants and the kind, frequency and timing
of any notice to be given. Prior to the exercise of their Warrants for shares of
Preferred Stock or Common Stock, holders of such Warrants will not have any
rights of holders of the Preferred Stock or Common Stock purchasable upon such
exercise and will not be entitled to dividend payments, if any, or voting rights
of the Preferred Stock or Common Stock purchasable upon such exercise.
 
EXERCISE OF WARRANTS
 
Each Warrant will entitle the holder thereof to purchase for cash or other
consideration such principal amount or such number of securities of the Company
at such exercise price as shall in each case be set forth in, or be determinable
as set forth in, the Prospectus Supplement relating to the Warrants offered
thereby. Warrants may be exercised as set forth in the Prospectus Supplement
relating to the Warrants offered thereby at any time up to the close of business
on the expiration date set forth in such Prospectus Supplement. After the close
of business on the expiration date (or such later expiration date as may be
extended by the Company), unexercised Warrants will become void.
 
Upon receipt of payment and the Warrant certificate properly completed and duly
executed at the corporate trust office of the Warrant Agent or any other office
indicated in the applicable Prospectus Supplement, the Company will, as soon as
practicable, forward the securities purchasable upon such exercise. If less than
all of the Warrants represented by such Warrant certificate are exercised, a new
Warrant certificate will be issued for the remaining Warrants.
 
MODIFICATIONS
 
Unless otherwise specified in the applicable Prospectus Supplement, each Warrant
Agreement and the terms of the Warrants and the Warrant certificates may be
amended by the Company and the Warrant Agent, without the consent of the
holders, for the purpose of curing any ambiguity, or of curing, correcting or
supplementing any defective or inconsistent provision therein or in any other
                                       47
<PAGE>   68
 
manner which the Company may deem necessary or desirable and which will not
adversely affect the interests of the holders of such Warrants in any material
respect.
 
                    DESCRIPTION OF STOCK PURCHASE CONTRACTS
                            AND STOCK PURCHASE UNITS
 
The Company may issue Stock Purchase Contracts, including contracts obligating
holders to purchase from the Company, and the Company to sell to the holders, a
specified number of shares of Common Stock or Preferred Stock at a future date
or dates. The consideration per share of Preferred Stock or Common Stock may be
fixed at the time the Stock Purchase Contracts are issued or may be determined
by reference to a specific formula set forth in the Stock Purchase Contracts.
The Stock Purchase Contracts may be issued separately or as a part of units
("Stock Purchase Units") consisting of a Stock Purchase Contract and Debt
Securities, Preferred Securities or debt obligations of third parties, including
U.S. Treasury securities, securing the holders' obligations to purchase the
Preferred Stock or the Common Stock under the Stock Purchase Contracts. The
Stock Purchase Contracts may require the Company to make periodic payments to
the holders of the Stock Purchase Units or vice versa, and such payments may be
unsecured or prefunded on some basis. The Stock Purchase Contracts may require
holders to secure their obligations thereunder in a specified manner.
 
The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units. The description in the Prospectus
Supplement will not purport to be complete and will be qualified in its entirety
by reference to the Stock Purchase Contracts, and, if applicable, collateral
arrangements and depositary arrangements, relating to such Stock Purchase
Contracts or Stock Purchase Units.
 
                              BOOK-ENTRY ISSUANCE
 
Unless otherwise specified in the applicable Prospectus Supplement, DTC will act
as Depositary or Subordinated Depositary, as the case may be, for Securities
issued in the form of Global Securities. Such Securities will be issued only as
fully-registered securities registered in the name of Cede & Co. (DTC's
nominee). One or more fully-registered Global Securities will be issued for such
Securities representing in the aggregate the total number of such Securities,
and will be deposited with or on behalf of DTC.
 
DTC is a limited purpose trust company organized under the New York Banking Law,
a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its Participants deposit with DTC. DTC also facilitates
the settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct Participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations ("Direct Participants"). DTC is owned by a number of its
Direct Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain custodial
relationships with Direct Participants, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
Purchases of Securities within the DTC system must be made by or through Direct
Participants, which will receive a credit for such Securities on DTC's records.
The ownership interest of each actual purchaser of each Security ("Beneficial
Owner") is in turn to be recorded on the Direct and
 
                                       48
<PAGE>   69
 
Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchases, but Beneficial Owners are expected to
receive written confirmations providing details of the transactions, as well as
periodic statements of their holdings, from the Direct or Indirect Participants
through which the Beneficial Owners purchased Securities. Transfers of ownership
interests in Securities issued in the form of Global Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners. Beneficial Owners will not receive certificates representing
their ownership interests in such Securities, except in the event that use of
the book-entry system for such Securities is discontinued.
 
DTC has no knowledge of the actual Beneficial Owners of the Securities issued in
the form of Global Securities; DTC's records reflect only the identity of the
Direct Participants to whose accounts such Securities are credited, which may or
may not be the Beneficial Owners. The Participants will remain responsible for
keeping account of their holdings on behalf of their customers.
 
Conveyance of notices and other communications by DTC to Direct Participants, by
Direct Participants to Indirect Participants, and by Direct Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.
 
Redemption notices shall be sent to Cede & Co. as the registered holder of
Securities issued in the form of Global Securities. If less than all of a series
of such Securities are being redeemed, DTC's current practice is to determine by
lot the amount of the interest of each Direct Participant to be redeemed.
 
Although voting with respect to Securities issued in the form of Global
Securities is limited to the holders of record of such Securities, in those
instances in which a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to such Securities. Under its usual procedures, DTC
would mail an omnibus proxy (the "Omnibus Proxy") to the issuer of such
Securities as soon as possible after the record date. The Omnibus Proxy assigns
Cede & Co.'s consenting or voting rights to those Direct Participants to whose
accounts such Securities are credited on the record date (identified in a
listing attached to the Omnibus Proxy).
 
Payments in respect of Securities issued in the form of Global Securities will
be made by the issuer of such Securities to DTC. DTC's practice is to credit
Direct Participants' accounts on the relevant payment date in accordance with
their respective holdings shown on DTC's records unless DTC has reason to
believe that it will not receive payments on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions and
customary practices and will be the responsibility of such Participant and not
of DTC, the Property Trustee, either Issuer or the Company, subject to any
statutory or regulatory requirements as may be in effect from time to time.
Payments to DTC are the responsibility of the issuer of the applicable
Securities, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursements of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
DTC may discontinue providing its services as Depositary or Subordinated
Depositary, as the case may be, with respect to any Securities at any time by
giving reasonable notice to the issuer of such Securities. In the event that a
successor Depositary or Subordinated Depositary, as the case may be, is not
obtained, individual Security certificates representing such Securities are
required to be printed and delivered. The Company, at its option, may decide to
discontinue use of the system of book-entry transfers through DTC (or a
successor Depositary or Subordinated Depositary, as the case may be).
 
The information in this section concerning DTC and DTC's book-entry system has
been obtained from sources that the Issuers and the Company believe to be
accurate, but the Issuers and the Company assume no responsibility for the
accuracy thereof. Neither the Issuers nor the Company
 
                                       49
<PAGE>   70
 
has any responsibility for the performance by DTC or its Participants of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.
 
                              PLAN OF DISTRIBUTION
 
Any of the Securities being offered hereby may be sold in any one or more of the
following ways from time to time: (i) through agents; (ii) to or through
underwriters; (iii) through dealers; and (iv) directly by the Company or, in the
case of Preferred Securities, by the Issuers to purchasers.
 
The distribution of the Securities may be effected from time to time in one or
more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices.
 
Sales of Common Stock offered hereby may be effected from time to time in one or
more transactions on the New York Stock Exchange or the Toronto Stock Exchange
or in negotiated transactions or a combination of such methods of sale, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at other negotiated prices.
 
Offers to purchase Securities may be solicited by agents designated by the
Company from time to time. Any such agent involved in the offer or sale of the
Securities in respect of which this Prospectus is delivered will be named, and
any commissions payable by the Company or the Issuers to such agent will be set
forth, in the applicable Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be deemed to
be an underwriter, as that term is defined in the Securities Act, of the
Securities so offered and sold.
 
If Securities are sold by means of an underwritten offering, the Company and, in
the case of an offering of Preferred Securities, the applicable Issuer will
execute an underwriting agreement with an underwriter or underwriters at the
time an agreement for such sale is reached, and the names of the specific
managing underwriter or underwriters, as well as any other underwriters, the
respective amounts underwritten and the terms of the transaction, including
commissions, discounts and any other compensation of the underwriters and
dealers, if any, will be set forth in the applicable Prospectus Supplement which
will be used by the underwriters to make resales of the Securities in respect of
which this Prospectus is being delivered to the public. If underwriters are
utilized in the sale of any Securities in respect of which this Prospectus is
being delivered, such Securities will be acquired by the underwriters for their
own account and may be resold from time to time in one or more transactions,
including negotiated transactions, at fixed public offering prices or at varying
prices determined by the underwriters at the time of sale. Securities may be
offered to the public either through underwriting syndicates represented by
managing underwriters or directly by one or more underwriters. If any
underwriter or underwriters are utilized in the sale of Securities, unless
otherwise indicated in the applicable Prospectus Supplement, the underwriting
agreement will provide that the obligations of the underwriters are subject to
certain conditions precedent and that the underwriters with respect to a sale of
such Securities will be obligated to purchase all such Securities if any are
purchased.
 
The Company or an Issuer, as applicable, may grant to the underwriters options
to purchase additional Securities, to cover over-allotments, if any, at the
initial public offering price (with additional underwriting commissions or
discounts), as may be set forth in the Prospectus Supplement relating thereto.
If the Company or an Issuer, as applicable, grants any over-allotment option,
the terms of such overallotment option will be set forth in the Prospectus
Supplement for such Securities.
 
If a dealer is utilized in the sale of the Securities in respect of which this
Prospectus is delivered, the Company or an Issuer, as applicable, will sell such
Securities to the dealer as principal. The dealer may then resell such
Securities to the public at varying prices to be determined by such dealer at
the time of resale. Any such dealer may be deemed to be an underwriter, as such
term is defined in
                                       50

the Securities Act, of the Securities so offered and sold. The name of the
dealer and the terms of the transaction will be set forth in the Prospectus
Supplement relating thereto.
 
Offers to purchase Securities may be solicited directly by the Company or an
Issuer, as applicable, and the sale thereof may be made by the Company or an
Issuer directly to institutional investors or others, who may be deemed to be
underwriters within the meaning of the Securities Act with respect to any resale
thereof. The terms of any such sales will be described in the Prospectus
Supplement relating thereto.
 
Securities may also be offered and sold, if so indicated in the applicable
Prospectus Supplement, in connection with a remarketing upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more firms ("remarketing firms"), acting as principals for their own
accounts or as agents for the Company or an Issuer, as applicable. Any
remarketing firm will be identified and the terms of its agreement, if any, with
the Company or such Issuer and its compensation will be described in the
applicable Prospectus Supplement. Remarketing firms may be deemed to be
underwriters, as that term is defined in the Securities Act, in connection with
the Securities remarketed thereby.
 
If so indicated in the applicable Prospectus Supplement, the Company or an
Issuer, as applicable, may authorize agents and underwriters to solicit offers
by certain institutions to purchase Securities from the Company or such Issuer
at the public offering price set forth in the applicable Prospectus Supplement
pursuant to delayed delivery contracts providing for payment and delivery on the
date or dates stated in the applicable Prospectus Supplement. Such delayed
delivery contracts will be subject to only those conditions set forth in the
applicable Prospectus Supplement. A commission indicated in the applicable
Prospectus Supplement will be paid to underwriters and agents soliciting
purchases of Securities pursuant to delayed delivery contracts accepted by the
Company or such Issuer, as applicable.
 
Agents, underwriters, dealers and remarketing firms may be entitled under
relevant agreements with the Company or an Issuer, as applicable, to
indemnification by the Company or such Issuer against certain liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, underwriters, dealers and remarketing firms may
be required to make in respect thereof.
 
Each series of Securities will be a new issue and, other than the Common Stock,
which is listed on the New York Stock Exchange and the Toronto Stock Exchange,
will have no established trading market. The Company may elect to list any
series of Securities on an exchange, and in the case of the Common Stock, on any
additional exchange, but, unless otherwise specified in the applicable
Prospectus Supplement, the Company shall not be obligated to do so. No assurance
can be given as to the liquidity of the trading market for any of the
Securities.
 
Agents, underwriters, dealers and remarketing firms may be customers of, engage
in transactions with, or perform services for, the Company and its subsidiaries
in the ordinary course of business.
