                           SUMMARY INFORMATION -- Q&A
 
This summary highlights selected information from this prospectus supplement and
the accompanying prospectus to help you understand the preferred securities. You
should carefully read this prospectus supplement and the accompanying prospectus
to understand fully the terms of the preferred securities, as well as the tax
and other considerations that are important to you in making a decision about
whether to invest in the preferred securities. You should pay special attention
to the "risk factors" section beginning on page S-6 of this prospectus
supplement to determine whether an investment in the preferred securities is
appropriate for you.
 
For your convenience, we make reference to specific page numbers in this
prospectus supplement and the accompanying prospectus for more detailed
information on some of the terms and concepts used throughout this prospectus
supplement.
 
WHAT ARE THE PREFERRED SECURITIES?
 
Each preferred security represents an undivided beneficial interest in the
assets of the trust. Each preferred security will entitle the holder to receive
quarterly cash distributions as described in this prospectus supplement. The
underwriters are offering a total of 6,000,000 preferred securities at a price
of $25 each. The underwriters may also purchase up to an additional
preferred securities at the same public offering price within 30 days of the
date of this prospectus supplement to cover any over-allotments. See
"Underwriting" beginning on page S-38.
 
WHO IS THE TRUST?
 
FW Preferred Capital Trust I (the "trust") is a Delaware business trust.
 
The trust will sell its preferred securities to the public and its common
securities to Foster Wheeler. The trust will use the proceeds from these sales
to buy a series of   % Junior Subordinated Deferrable Interest Debentures due
2029 (the "junior subordinated debentures") from Foster Wheeler with the same
financial terms as the preferred securities.

There are five trustees of the trust. Three of them, the "administrative
trustees," are officers of Foster Wheeler. Harris Trust and Savings Bank will
act as the "property trustee" of the trust and Wilmington Trust Company will act
as the "Delaware trustee."
 
WHO IS FOSTER WHEELER?
 
Foster Wheeler is a global company providing engineering services and products
to a broad range of industries through its engineering and construction, energy
equipment and power systems groups.
 
WHEN WILL YOU RECEIVE QUARTERLY DISTRIBUTIONS AND HOW MUCH WILL YOU BE PAID?
 
If you purchase the preferred securities, you will be entitled to receive
cumulative cash distributions at an annual rate of   %. Distributions will
accrue from the date the trust issues the preferred securities and will be paid
quarterly in arrears on              ,              ,              and
             of each year, beginning              , 1999.
 
WHEN CAN PAYMENT OF YOUR DISTRIBUTIONS BE DEFERRED?
 
Foster Wheeler can, on one or more occasions, defer interest payments on the
junior subordinated debentures for up to 20 consecutive quarterly periods unless
an event of default (see page S-29) under the junior subordinated debentures has
occurred and is continuing. In other words, Foster Wheeler may declare a five-
year interest payment moratorium on the junior subordinated debentures. A
deferral of interest payments cannot extend, however, beyond the maturity date
of the junior subordinated debentures (which is              , 2029).
 
If Foster Wheeler defers interest payments on the junior subordinated
debentures, the trust
 
                                       S-3
<PAGE>   4
 
will also defer distributions on the preferred securities. During this deferral
period, distributions will continue to accrue on the preferred securities at an
annual rate of   %, compounded quarterly. Also, the deferred distributions will
themselves accrue interest at an annual rate of   % (to the extent permitted by
law). Once Foster Wheeler makes all interest payments on the junior subordinated
debentures, with accrued interest, it can again postpone interest payments on
the junior subordinated debentures if no event of default under the junior
subordinated debentures has occurred and is continuing.
 
During any period in which Foster Wheeler defers interest payments on the junior
subordinated debentures, Foster Wheeler will not be permitted to do any of the
following (with limited exceptions described on pages S-29 and S-30):
 
- - pay a dividend or make any other payment or distribution on its capital stock;
 
- - redeem, purchase or make a liquidation payment on any of its capital stock;
 
- - make an interest, principal or premium payment, or repay, repurchase or
  redeem, any of its debt securities that rank equal with or junior to the
  junior subordinated debentures; or
 
- - make any guarantee payment with respect to any guarantee by Foster Wheeler of
  debt securities of any of its subsidiaries, if the guarantee ranks equal to,
  or junior in right of payment to the junior subordinated debentures.
 
If Foster Wheeler defers payments of interest on the junior subordinated
debentures, the preferred securities will at that time be treated as being
issued with original issue discount for United States federal income tax
purposes. This means you would be required to recognize interest income with
respect to distributions (even if they are deferred) and include such amounts in
your gross income for United States federal income tax purposes before you
receive any cash distributions relating to such interest payments. See "United
States Federal Income Tax Consequences" beginning on page S-30.

WHEN CAN THE TRUST REDEEM THE PREFERRED SECURITIES?
 
The trust will redeem all of the outstanding preferred securities when the
junior subordinated debentures are paid at maturity on              , 2029. In
addition, if Foster Wheeler redeems any junior subordinated debentures before
their maturity, the trust will use the cash it receives on the redemption of the
junior subordinated debentures to redeem, on a pro rata basis, preferred
securities and common securities having a total liquidation amount equal to the
total principal amount of the junior subordinated debentures redeemed.
 
Foster Wheeler can redeem the junior subordinated debentures before their
maturity at 100% of their principal amount plus accrued and unpaid interest to
the date of redemption:
 
- - on one or more occasions any time on or after              , 2004; and
 
- - at any time, if certain changes in tax or investment company law occur (each
  of which is a "Special Event" and each of which is more fully described on
  pages S-24 and S-25, provided Foster Wheeler chooses to redeem within 90 days
  of the occurrence of the Special Event. If Foster Wheeler redeems the junior
  subordinated debentures because of a Special Event, it must redeem all of
  them.
 
HOW ARE THE PREFERRED SECURITIES GUARANTEED?
 
Foster Wheeler will fully and unconditionally guarantee the preferred securities
on a subordinated basis based on:
 
- - its obligations under a guarantee of the preferred securities (the
  "guarantee"); and
 
- - its obligations under the declaration of trust and the junior subordinated
  indenture.
 
However, if Foster Wheeler does not make a payment on the junior subordinated
debentures, the trust will not have sufficient funds to make payments on the
preferred securities. The guar-
 
                                       S-4
<PAGE>   5
 
antee does not cover payments when the trust does not have sufficient funds to
make payments on the preferred securities. In addition, Foster Wheeler's
obligations under the guarantee are subordinate to its obligations to make
payments on all of its other liabilities.
 
WHEN COULD THE JUNIOR SUBORDINATED DEBENTURES BE DISTRIBUTED TO YOU?
 
Foster Wheeler has the right to terminate the trust at any time. If Foster
Wheeler decides to terminate the trust, the trust will redeem the preferred
securities by distributing the junior subordinated debentures to holders of the
preferred securities and the common securities on a pro rata basis.
 
WHAT HAPPENS IF THE TRUST IS TERMINATED AND THE JUNIOR SUBORDINATED DEBENTURES
ARE NOT DISTRIBUTED?
 
The trust may also terminate in circumstances where the junior subordinated
debentures will not be distributed. In those situations, the trust will pay the
liquidation amount of $25 for each preferred security plus unpaid distributions
to the date such payment is made. The trust will be able to make this
distribution of cash only if the junior subordinated debentures are redeemed by
Foster Wheeler.
 
WILL THE PREFERRED SECURITIES BE LISTED ON A STOCK EXCHANGE?
 
The trust has applied to have the preferred securities listed on the NYSE under
the symbol "FWC-A". If approved for listing, trading is expected to commence
within 30 days after the preferred securities are first issued. You should be
aware that the listing of the preferred securities will not necessarily ensure
that a liquid trading market will be available for the preferred securities.
 
If the trust distributes the junior subordinated debentures, Foster Wheeler will
use its best efforts to list them on the NYSE or any other exchange or other
organization on which the preferred securities are then listed.
 
IN WHAT FORM WILL THE PREFERRED SECURITIES BE ISSUED?

The preferred securities will be represented by one or more global securities
that will be deposited with and registered in the name of The Depository Trust
Company, New York, New York ("DTC") or its nominee. This means that you will not
receive a certificate for your preferred securities. The trust expects that the
preferred securities will be ready for delivery through DTC on or about
            , 1999.

                                  RISK FACTORS
 
Before purchasing any preferred securities, you should carefully read the
following risk factors and the other sections of this prospectus supplement and
the accompanying prospectus. In addition, because holders of preferred
securities may receive junior subordinated debentures in exchange for their
preferred securities if the trust is liquidated, you are also making an
investment decision with regard to the junior subordinated debentures. Thus, you
should also carefully read the information regarding the junior subordinated
debentures contained in this prospectus supplement and the accompanying
prospectus.
 
RISK FACTORS RELATING TO FOSTER WHEELER
 
HIGH LEVEL OF DEBT
 
Foster Wheeler has debt under bank loans and other debt securities that have
been sold to investors. As of September 25, 1998, Foster Wheeler's total debt
amounted to approximately $1,069.8 million, or 65% of Foster Wheeler's total
capitalization. However, a portion of this debt (approximately $436.1 million)
was borrowed by special-purpose subsidiaries to finance projects related to
Foster Wheeler's Power Systems Group. There is limited recourse to Foster
Wheeler for repayment of such debt, but Foster Wheeler often guarantees
completion and operating performance of these projects. The junior subordinated
indenture does not limit the amount of debt that Foster Wheeler may incur in the
future.
 
Over the last five years, Foster Wheeler has been required to allocate a greater
portion of its earnings to pay interest on its debt. See "Ratio of Earnings to
Fixed Charges" on page 3 of the accompanying prospectus. After paying interest
on its debt, Foster Wheeler has less funds available for working capital,
capital expenditures, acquisitions and other business purposes. This could
affect Foster Wheeler's ability to respond to changing market conditions or to
compete effectively in its markets.
 
As a result of certain charges relating to the Robbins Project (see pages S-11
and S-12 for a discussion of these charges), Foster Wheeler is not in compliance
with its financial covenants under its existing revolving credit facility.
Foster Wheeler has, however, received a waiver of those covenants through
February 15, 1999. In addition, Foster Wheeler has received commitments from a
group of lenders for a $400.0 million revolving credit facility which will
replace the current revolving credit facility. This new revolving credit
facility is expected to be available by February 15, 1999. However, Foster
Wheeler cannot assure you that the new revolving credit facility will be
available by such time, or if it is not, that Foster Wheeler will be able to get
additional waivers from its existing lenders.
 
POSSIBLE DELAYS OR CANCELLATION OF PROJECTS INCLUDED IN BACKLOG
 
As of September 25, 1998, Foster Wheeler's backlog amounted to approximately
$7.9 billion. Backlog consists of future revenues that Foster Wheeler expects to
receive.
 
The dollar amount of backlog does not necessarily indicate the future earnings
of Foster Wheeler related to the performance of such work. Backlog includes
expected receipts under signed contracts as well as under agreed letters of
intent which Foster Wheeler's management has determined are likely to be
performed. Although backlog represents only business which is considered firm,
cancellations or scope adjustments may occur. Due to factors outside Foster
Wheeler's control, such as changes in project schedules, Foster Wheeler cannot
predict with certainty the portion of backlog that will not be performed.
 
In addition, even where a project proceeds as scheduled, it is possible that the
parties with which Foster Wheeler has contracted (many of which are large
multinational corporations, however) may default and fail to pay amounts owed to
Foster Wheeler.
 
                                       S-6
<PAGE>   7
 
OPERATIONS IN ASIA
 
Foster Wheeler has operations in several countries in Asia, including China,
Singapore, Malaysia and Thailand. These operations include engineering and
construction and the supply of energy equipment. Current economic conditions in
this region have caused delays in the award of some projects.
 
As of September 25, 1998, approximately 24% of Foster Wheeler's total backlog
represented revenues Foster Wheeler expects to receive over time from projects
in Asia, or sales of equipment to this region. Most of this amount relates to
projects being led by multinational corporations or state-controlled entities,
and none of the projects in Foster Wheeler's Asian backlog have been canceled or
delayed to date. However, it is possible that the continuing economic
uncertainty in Asia may result in unexpected delays or cancellations of projects
in which Foster Wheeler is involved or may in the future become involved. In
addition, Foster Wheeler cannot be sure that economic conditions in Asia will
improve in the future.
 
WORKING CAPITAL REQUIREMENTS
 
Foster Wheeler's business requires a significant amount of working capital.
Working capital is necessary to finance purchase of materials and performance of
engineering, construction, and other work on projects before payment is received
from customers.
 
Working capital requirements have increased because Foster Wheeler has satisfied
requests from its customers, especially in the Energy Equipment Group, for more
favorable payment terms under contracts. Such requests generally include lower
advance payments and payment schedules that are less favorable to Foster
Wheeler. Foster Wheeler intends, however, to pass on all or a portion of these
costs to customers through higher contract prices.
 
Higher working capital requirements may adversely affect Foster Wheeler's
financial condition and results of operations.
 
INCREASE IN LUMP-SUM (FIXED PRICE) CONTRACTS
 
Over the last several years, in response to changing customer demands, the
proportion of Foster Wheeler's revenues derived from "lump-sum" contracts has
increased. Under these contracts, Foster Wheeler is required to design, engineer
and construct facilities and manufacture equipment in exchange for a fixed
amount, which is generally not adjusted to reflect the actual costs incurred by
Foster Wheeler to fulfill its responsibilities under the contract.
 
Lump-sum contracts may result in significant losses when costs are greater than
anticipated. Moreover, factors beyond Foster Wheeler's control may result in
higher costs. For example, costs may increase because of unforeseen conditions,
delays in performance or defaults by subcontractors, increases in costs of
equipment purchased by Foster Wheeler for the projects, and other factors.
 
CONCENTRATION IN PARTICULAR INDUSTRIES
 
Foster Wheeler derives a significant amount of its revenues from services
provided to corporations that are concentrated in five industries: oil,
chemicals, pharmaceuticals, environmental remediation and power generation.
Unfavorable economic conditions in one or more of these industries could
significantly affect Foster Wheeler's financial condition and results of
operations.
 
As a result of certain changes in law and changing economic conditions, Foster
Wheeler has experienced reduced earnings and/or losses at certain of its
waste-to-energy facilities. As is discussed in more detail on pages S-11 and
S-12, certain of those losses are expected to continue. In addition, Foster
Wheeler cannot predict with certainty whether it will suffer reduced earnings or
losses at its other facilities in the future.
 
POSSIBLE INABILITY TO REPATRIATE FOREIGN EARNINGS
 
Foster Wheeler has substantial foreign operations. Foster Wheeler's foreign
operations are subject to the normal risks of doing business
 
                                       S-7
<PAGE>   8
 
overseas, including the risk that it will be unable to convert foreign earnings
into U.S. dollars or transfer such amounts out of foreign countries without
significant costs. Inability to convert these amounts to U.S. dollars or
transfer them out of foreign countries could result from government action,
currency market failure, or other factors.
 
Foster Wheeler has not experienced problems repatriating its foreign earnings to
date, due to the high concentration of foreign earnings in Foster Wheeler's
profit centers in Western Europe. However, Foster Wheeler cannot assure you that
it will not encounter such problems in the future. Inability to repatriate
foreign earnings could adversely affect Foster Wheeler's financial condition.
 
RISK FACTORS RELATING TO THE PREFERRED SECURITIES
 
SUBORDINATION
 
Foster Wheeler's obligations under the junior subordinated debentures and the
guarantee are junior in right of payment to all of Foster Wheeler's senior
indebtedness. This means that Foster Wheeler cannot make any payments on the
junior subordinated debentures or the guarantee if Foster Wheeler is in default
on any of its senior indebtedness. In addition, in the event of the bankruptcy,
liquidation or dissolution of Foster Wheeler, its assets must be used to pay off
its senior indebtedness in full before any payments may be made on the junior
subordinated debentures or the guarantee. Almost all of Foster Wheeler's
existing indebtedness is senior indebtedness.
 
The junior subordinated indenture, the guarantee, the declaration of trust and
the expense agreement do not limit the ability of Foster Wheeler to incur
additional senior indebtedness.
 
The ability of the trust to pay amounts due on the preferred securities is
completely dependent upon Foster Wheeler's making payments on the junior
subordinated debentures when due.
 
For more information please see "Description of Guarantees -- Status of the
Guarantees" and "Description of Debt Securities -- Junior Subordinated
Debentures -- Subordination" on pages 30 and 18, respectively, of the
accompanying prospectus.
 
FOSTER WHEELER'S ABILITY TO DEFER DISTRIBUTIONS HAS TAX CONSEQUENCES FOR YOU AND
MAY AFFECT THE TRADING PRICE OF THE PREFERRED SECURITIES
 
So long as the junior subordinated debentures are not in default, Foster Wheeler
may, on one or more occasions, defer interest payments on the junior
subordinated debentures for up to 20 consecutive quarters. Since interest
payments on the junior subordinated debentures fund the distributions on the
preferred securities, each such deferral would result in a corresponding
deferral of distributions on the preferred securities. However, you would still
accrue distributions at an annual rate of      %, compounded quarterly.
 
Foster Wheeler does not currently intend to defer interest payments on the
junior subordinated debentures. However, if it does so in the future, the
preferred securities may trade at a price that does not fully reflect the value
of the accrued but unpaid distributions.
 
If you sell preferred securities during a deferral period, you may not receive
the same return on your investment as someone who continues to hold the
preferred securities. In addition, Foster Wheeler's right to defer interest
payments on the junior subordinated debentures could mean that the market price
for the preferred securities may be more volatile than that of other securities
without interest deferral rights.
 
At the end of any deferral period, Foster Wheeler must pay all of the accrued
interest on the junior subordinated debentures. Foster Wheeler must also pay
interest on the deferred interest payments at an annual rate of      %. If
Foster Wheeler pays these amounts, it may elect to begin a new deferral period.
There is no other limitation on the number of times that Foster Wheeler may
elect to begin a new deferral period except that no deferral period may extend
beyond the maturity date of the junior subordinated debentures. See "Certain

dinated Debentures and Guarantee -- Option to Defer Interest Payments" on pages
S-22 and S-29, respectively.
 
During a deferral period, you will be required to accrue interest income for
United States federal income tax purposes in respect of your pro rata share of
the junior subordinated debentures held by the trust. As a result, you must
include the accrued interest in your gross income for United States federal
income tax purposes prior to your receiving any cash distribution. You will also
not receive the cash distribution related to any accrued and unpaid interest if
you sell preferred securities before the end of a deferral period. See "United
States Federal Income Tax Consequences -- Interest Income and Original Issue
Discount" and "-- Sale, Exchange or Retirement of Preferred Securities" on pages
S-32 and S-33 for more information regarding the tax consequences of purchasing
the preferred securities.
 
THE PREFERRED SECURITIES MAY BE REDEEMED AT ANY TIME IF A SPECIAL EVENT OCCURS
 
If a Special Event (see pages S-24 and S-25) occurs, Foster Wheeler can redeem
all of the junior subordinated debentures at a price equal to the principal
amount of the junior subordinated debentures plus accrued interest. If such a
redemption happens, the trust must use the redemption price it receives to
redeem the preferred securities.
 
See "-- Potential Changes in Tax Law or Interpretation" beginning on page S-33
for a discussion of certain legislative proposals that, if adopted, could give
rise to a Special Event, which would permit the redemption of the preferred
securities prior to              , 2004.
 
OPTIONAL REDEMPTION
 
Foster Wheeler may redeem the junior subordinated debentures, in whole or in
part, at any time on or after              , 2004. If Foster Wheeler redeems
junior subordinated debentures, the trust must redeem an equivalent amount of
preferred securities at the same time at a redemption price equal to the
liquidation amount of the preferred securities plus any unpaid distributions.
See "Certain Terms of the Junior Subordinated Debentures and
Guarantee -- Redemption" on page S-29 for more information.
 
EXCHANGE OF PREFERRED SECURITIES FOR JUNIOR SUBORDINATED DEBENTURES
 
Foster Wheeler has the right to terminate the trust and, after paying all of the
trust's debts, to cause the trust to distribute junior subordinated debentures
in exchange for all of the outstanding preferred securities. For further
information, see "Certain Terms of the Preferred Securities -- Optional
Liquidation of Trust and Distribution of Junior Subordinated Debentures" on page
S-25.
 
Assuming, as expected, that the trust will not be taxable as a corporation under
current United States federal income tax law, this exchange should not be a
taxable event to holders of the preferred securities. However, if the trust
becomes subject to United States federal income tax with respect to income
received or accrued on the junior subordinated debentures, a distribution of the
junior subordinated debentures by the trust could be a taxable event to the
trust and the holders of the preferred securities. For further information, see
"United States Federal Income Tax Consequences -- Distribution of Junior
Subordinated Debentures to Beneficial Owners" beginning on page S-32.
 
RIGHTS UNDER THE GUARANTEE; DIRECT ACTION
 
Foster Wheeler guarantees the following payments on the preferred securities,
but only to the extent that the trust has funds available to make such payments:
 
- - accrued distributions on the preferred securities;
 
- - the redemption price of any preferred securities called for redemption; and
 
- - upon a voluntary or involuntary dissolution, winding-up or liquidation of the
  trust (unless the junior subordinated debentures are distributed to holders of
  the preferred securities), the liquidation amount of the preferred securities
  and all accrued distributions to the date of payment.
 
                                       S-9
<PAGE>   10
 
The guarantee is subordinated to all senior indebtedness of Foster Wheeler as
described under "Description of Guarantees -- Status of the Guarantees" on page
30 of the accompanying prospectus.
 
The holders of a majority in liquidation amount of the outstanding preferred
securities (a "majority") have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the guarantee trustee
under the guarantee or to direct the exercise of any power given to the
guarantee trustee under the guarantee. If the guarantee trustee does not enforce
the guarantee, any holder of preferred securities may proceed directly against
Foster Wheeler to enforce its rights under the guarantee without first
proceeding against the trust, the guarantee trustee or anybody else.
 
If Foster Wheeler defaults on the junior subordinated debentures, the trust will
lack funds for the payments on the preferred securities. If this happens,
holders of preferred securities will not be able to rely upon the guarantee for
payment of such amounts. Instead, if Foster Wheeler does not pay any amounts on
the junior subordinated debentures when due, then a holder of preferred
securities may proceed directly against Foster Wheeler for payment of any
amounts due on the preferred securities of such holder.
 
For more information, see "Description of Debt Securities -- Junior Subordinated
Debentures -- Enforcement of Certain Rights by Holders of Preferred Securities"
and "Description of Guarantees" on pages 18 and 29-32 of the accompanying
prospectus.
 
By purchasing preferred securities, each holder of preferred securities agrees
to the provisions of the guarantee and the junior subordinated indenture.
 
LIMITED VOTING RIGHTS
 
You will only have limited voting rights. In particular, only Foster Wheeler can
elect and remove trustees, except under certain limited circumstances. For more
information, see "FW Preferred Capital Trust I" on page S-21.
 
STOCK EXCHANGE LISTING
 
We have applied to have the preferred securities listed on the NYSE. However, if
the preferred securities are not listed on a national securities exchange or the
NASDAQ National Market, and the underwriters do not make a market in them, the
market for the preferred securities may not be liquid, and they may be difficult
to sell.
 
POTENTIAL CHANGES IN TAX LAW OR INTERPRETATION
 
Foster Wheeler understands that the IRS recently challenged another company's
deduction for interest paid on a debt instrument similar in some respects to the
junior subordinated debentures and issued to an entity similar to the trust.
Based on available information, Foster Wheeler and the trust do not believe that
this challenge will affect Foster Wheeler's ability to deduct interest payments
on the junior subordinated debentures. However, you should be aware that a Tax
Court decision in that case in favor of the IRS, or other unrelated
developments, could cause a Tax Event. See "United States Federal Income Tax
Consequences" starting on page S-30. Laws and regulations have also been
proposed in the past which, if adopted retroactively, could also cause a Tax
Event, although such legislation and regulations are not currently pending. For
more information, see "United States Federal Income Tax
Consequences -- Potential Changes in Tax Law or Interpretation" and "Certain
Terms of the Preferred Securities -- Redemption" on pages S-33 and S-24,
respectively.

                        INFORMATION ABOUT FOSTER WHEELER
 
FOSTER WHEELER CORPORATION
 
Foster Wheeler, a New York corporation, was organized in 1900. Foster Wheeler
and its subsidiaries operate through three business groups: the Engineering and
Construction Group, the Energy Equipment Group and the Power Systems Group.
 
ENGINEERING AND CONSTRUCTION GROUP
 
The Engineering and Construction Group designs, engineers and constructs
petroleum, chemical, petrochemical and alternative-fuels facilities and related
infrastructure. These facilities and infrastructure include power generation and
distribution facilities, production terminals, pollution control equipment and
water treatment facilities, as well as process plants for the production of fine
chemicals, pharmaceuticals, dyestuffs, fragrances, flavors, food additives and
vitamins. The group also provides a broad range of environmental remediation
services, together with related technical, design and regulatory services.
 
ENERGY EQUIPMENT GROUP
 
The Energy Equipment Group designs, manufactures and builds steam generating and
auxiliary equipment for power stations and industrial markets worldwide. The
group's steam generating equipment includes a full range of fluidized bed and
conventional boilers, which burn coal, oil, gas, biomass and other municipal
solid waste, waste wood and low-Btu gases. The group's auxiliary equipment
includes feedwater heaters, steam condensers, heat-recovery equipment and
low-NOx burners. The group also provides site services related to these
products, including plant erection, maintenance engineering, plant upgrading and
life extension, and plant repowering. Finally, the group provides research
analysis and performs experimental work in fluid dynamics, heat transfer,
combustion and fuel technology, materials engineering and solids mechanics.
 
At the end of June 1997, the Energy Equipment Group sold substantially all of
the operations of Glitsch International, Inc. Glitsch International had provided
proprietary solutions and systems for many separation applications, and had
manufactured highly engineered chemical separations equipment for the petroleum
refining, petrochemical, chemical and gas processing industries.
 
POWER SYSTEMS GROUP
 
The Power Systems Group builds, owns, leases and operates cogeneration,
independent power production and resource recovery facilities, as well as
facilities for the process and petrochemical industries, utilizing Foster
Wheeler's strengths in design, engineering, manufacturing and construction. The
group generates revenues from construction and operating activities performed
under long-term off-take and operating and maintenance agreements, and also from
returns on its equity positions. The group operates through special-purpose
subsidiaries, with one established for each project. Each special-purpose
subsidiary manages its project from the permitting stage through construction
and operation of the plant. All project debt of the special-purpose subsidiaries
is limited-recourse. However, Foster Wheeler often provides support for projects
in the form of guarantees of the completion and operating performance of the
project. The group refinances its equity interest in selected projects from time
to time when such refinancing will result in reduction of risk, a lower
effective financing cost or a potential increased return on investment.
 
In the fourth quarter of 1998, Foster Wheeler restated previously reported
earnings to reverse a $60.0 million charge against earnings that was taken in
the second quarter of 1997 and $127.9 million of a $175.0 million charge against
earnings that was taken in the third quarter of 1998. These charges related to
the anticipated losses of a waste-to-energy plant located in the Village of
Robbins, Illinois (the "Robbins Project"). These losses resulted from a change
in law in Illinois that significantly reduced the revenues of the Robbins
Facility. These losses
 
                                      S-11
<PAGE>   12
 
were initially recorded because, as a result of this change in law, Foster
Wheeler expected that the income and cash to be generated by the Robbins Project
would not be sufficient to cover the lease expense. Based on a further detailed
review in conjunction with the filing of the registration statement of which
this prospectus supplement forms a part, Foster Wheeler changed its accounting
for costs associated with this operating lease agreement to reflect them as
charges to earnings as lease costs are incurred. As a result, Foster Wheeler
expects to record losses of $127.9 million in future periods related to the
operations of the Robbins Facility. The $175.0 million charge had initially been
taken to fully reserve for all asset impairments and financial guarantees of
Foster Wheeler relating to the Robbins Facility. For further information
regarding the Robbins Project, see Foster Wheeler's Quarterly Report on Form
10-Q/A, for the fiscal quarter ended September 25, 1998, which is incorporated
by reference in this prospectus supplement.
 
As a result of these charges, Foster Wheeler is not in compliance with its
financial covenants under its existing revolving credit facility. Foster Wheeler
has, however, received a waiver of those covenants through February 15, 1999. In
addition, Foster Wheeler has received commitments from a group of lenders for a
$400.0 million revolving credit facility (the "New Revolving Credit Facility")
which will replace the current revolving credit facility. The New Revolving
Credit Facility is expected to be available by February 15, 1999 and will
consist of two tranches, a $100.0 million tranche with a maturity of 364 days
and a $300.0 million tranche with a maturity of four years, and each bearing
interest at floating rates. For further information regarding Foster Wheeler's
financing arrangements, see Foster Wheeler's Annual Report on Form 10-K/A for
the fiscal year ended December 26, 1997 and its Quarterly Report on Form 10-Q/A,
for the fiscal quarter ended September 25, 1998, both of which are incorporated
by reference in this prospectus supplement.
 
The Power Systems Group consists of the following projects:

OPERATIONS
 
Foster Wheeler markets its services and products through a staff of sales and
marketing personnel, and through a network of sales representatives. Foster
Wheeler operates globally, and approximately two-thirds of its revenues comes
from business outside of the United States. One half of these foreign revenues
comes from Europe. The operations of Foster Wheeler's three business groups are
not seasonal, nor are these businesses dependent on a limited group of
customers. No single customer accounted for 10% or more of Foster Wheeler's
consolidated revenues in fiscal 1995, 1996 and 1997, although in any given year
one customer may have accounted for a significant share of these revenues.
 
Foster Wheeler obtains the materials used in its manufacturing and construction
operations from both domestic and foreign sources. These materials consist
mainly of steel products and manufactured items. Foster Wheeler depends heavily
on foreign sources for these materials, particularly for overseas projects.
Generally, lead time for delivery of materials is not a problem.
 
Foster Wheeler owns and licenses patents, trademarks and know-how in each of its
industry groups. The duration of these licenses, patents and trademarks varies.
No business group is materially dependent on any particular or related group of
patents, trademarks or licenses. Foster Wheeler has licensed companies
throughout the world to manufacture marine and stationary steam generators and
related equipment as well as other products. Foster Wheeler's principal
licensees are in Finland, Japan, The Netherlands, Italy, Spain, Portugal, Norway
and England.
 
Foster Wheeler generally custom designs and manufactures products for its
customers, rather than manufacturing products for inventory. In the Engineering
and Construction Group and the Energy Equipment Group, customers often make a
down payment at the time a contract is entered into. The customer then makes
progress payments until the contract is completed and the work has been accepted
by the customer.
 
BACKLOG
 
As of September 25, 1998, Foster Wheeler had a backlog of firm orders of
$7,871.8 million compared to a backlog of $7,222.6 million as of September 26,
1997. The dollar amount of these backlog orders does not necessarily indicate
that Foster Wheeler will reach a certain level of future earnings through work
related to the orders. Even though these backlog figures represent only orders
that Foster Wheeler's management considers to be "firm," it is possible that
orders will be canceled or scaled down. It may take up to four years from the
time a contract is entered into to complete performance under the contract. Due
to other factors that are outside of Foster Wheeler's control, such as changes
in project schedules, it
 
                                      S-13
<PAGE>   14
 
is not possible to predict with certainty the portion of backlog that will not
be completed.
 
A considerable portion of the backlog for both the Engineering and Construction
Group and the Energy Equipment Group is derived from projects in Asia. The Asian
backlog in the Engineering and Construction Group largely consists of contracts
denominated in US dollars with large multinational corporations (or in one case,
with a national oil and gas company geared toward export). A large portion of
the Asian backlog in the Energy Equipment Group consists of contracts with
Chinese companies financed through or guaranteed by United States, European or
Japanese export credit agencies.
 
Foster Wheeler's backlog by business groups as of September 25, 1998 and
September 26, 1997 is as follows:

POSITION IN THE MARKET
 
Many companies compete in the engineering and construction segment of Foster
Wheeler's business. Based on information contained in industry publications,
Foster Wheeler's management estimates that Foster Wheeler is among the ten
largest companies involved in the design and construction of petroleum
refineries and chemical plants. Neither Foster Wheeler nor any other single
company accounts for a large percentage of the total volume of such business.
 
Many companies compete internationally in the Energy Equipment segment of Foster
Wheeler's business. Based on industrial surveys and trade association materials,
Foster Wheeler's management estimates that Foster Wheeler is among the ten
largest suppliers of utility and industrial-size steam generating and auxiliary
equipment in the world, and is among the three largest in the United States.
 
RESEARCH AND DEVELOPMENT
 
Customers in Foster Wheeler's industries generally award contracts on the basis
of price, delivery, performance and service. Foster Wheeler is continually
engaged in research and development efforts, focusing on performance and
analytical services related to current projects, as well as on the development
of new products and processes. During 1997, approximately $16.1 million was
spent on these research activities, compared to $16.9 million in 1996 and $11.1
million in 1995. In addition, Foster Wheeler conducts research activities that
are paid for by customers. Foster Wheeler's customers paid it approximately
$40.4 million in 1997 to perform research activities compared to $29.6 million
in 1996, and $25.9 million in 1995.

GOVERNMENT REGULATION
 
Foster Wheeler and its domestic subsidiaries are required to comply with
federal, state and local environmental, occupational health and product safety
laws. Except where stated otherwise in this document (or the documents we refer
you to in this document), Foster Wheeler believes all of its operations comply
with these laws. Foster Wheeler does not anticipate incurring any extraordinary
expenses to remain in compliance with these laws, and its compliance with these
laws should not have a material adverse effect on Foster Wheeler's earnings or
cash flows.
 
EMPLOYEES
 
Foster Wheeler had approximately 11,090 full-time employees on December 26,
1997. The following table shows the number of full-time employees of Foster

           SELECTED CONSOLIDATED FINANCIAL DATA AND OTHER INFORMATION
 
Below you will find selected financial information for Foster Wheeler and its
consolidated subsidiaries, for each of the three fiscal years ended on December
26, 1997. This information has been derived from the audited consolidated
financial statements of the corporation and its consolidated subsidiaries
included in Foster Wheeler's Annual Report on Form 10-K/A filed for the fiscal
year ended December 26, 1997, which is incorporated herein by reference. You
should read this summary together with the detailed information contained in the
Annual Report on Form 10-K/A. The information included for the nine months ended
September 25, 1998 has not been audited, but in the opinion of Foster Wheeler's
management, this information reflects all adjustments that are necessary for a
fair presentation of Foster Wheeler's financial condition and results of
operation for these periods. All of the adjustments made to this information are
of a normal, recurring nature. The results for the nine months ended September
25, 1998 are not necessarily indicative of Foster Wheeler's business performance
for the full year of 1998, or for any other interim period. In conformity with
generally accepted accounting principles, management must make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expense during the reporting
period. Actual results could differ from those estimates.

- -------------------------
 
 *  The effect of stock options was not included in the calculation of diluted
    earnings per share as these shares were antidilutive due to the 1998 loss.
 
(1) During the fourth quarter of 1995, Foster Wheeler acquired the
    power-generation business of A. Ahlstrom Corporation, "Pyropower."
 
(2) In the third quarter of 1998, the Corporation recorded a $47,100 charge
    related to the Robbins Resource Recovery Facility and a valuation allowance
    of $60,000 for deferred tax assets that more likely than not will not be
    recovered.
 
(3) Includes in 1997 a net charge of $50,900 ($37,400 after tax) consisting of
    the following pre-tax items: Second quarter amounts: gain on sale of Glitsch
    International, Inc.'s operations, $56,400; provision for reorganization
    costs of the Energy Equipment Group, $32,000; and write-downs of long-lived
    assets, $6,500; Third quarter amounts: contract write-downs, $24,000
    (Engineering and Construction Group) and $30,000 (Energy Equipment Group);
    Fourth quarter amount: realignment of the Engineering and Construction
    Group's European operations, $14,800.
 
(4) Includes a 1996 provision of $24,000 ($15,600 after taxes) for asbestos
    claims.
 
(5) Includes a 1995 provision of $50,120 ($46,500 after taxes) for
    reorganization costs.
 
(6) Previously reported earnings have been restated to reverse a charge of
    $60,000 that was taken in the second quarter of 1997 and a charge of
    $127,900 that was taken in the third quarter of 1998 as part of a larger
    $175,000 provision. These charges related to the anticipated losses of the
    Robbins Project. These losses were initially provided for because Foster
    Wheeler does not expect the income and cash to be generated by the Robbins
    Project to be sufficient to cover the lease expense. Based on further
    detailed review and analysis, Foster Wheeler changed its accounting for
    costs associated with this operating lease agreement to reflect such as
    charges to earnings as lease costs are incurred. Since Foster Wheeler has a
    guarantee to continue to operate the facility, it was determined that the
    losses should be recognized as incurred and not accrued based on probable
    scenarios. As a result, Foster Wheeler expects to record losses of $127,900
    in future periods related to the operations of the Robbins Facility. The
    $175,000 charge was initially taken to fully reserve for all asset
    impairments and financial guarantees thereunder.

The following table shows the consolidated capitalization of Foster Wheeler and
its subsidiaries as of September 25, 1998. The "As Adjusted" column indicates
how the offering of the preferred securities would have affected Foster
Wheeler's capitalization if the preferred securities had been issued on
September 25, 1998, assuming that the underwriters' overallotment option was not
exercised. You should read this information together with the consolidated
financial statements, including the notes contained in the financial statements,
of Foster Wheeler and its subsidiaries, which are incorporated by reference in

                          FW PREFERRED CAPITAL TRUST I
 
FW Preferred Capital Trust I is a business trust organized under Delaware law.
Foster Wheeler established this trust by (1) filing a certificate of trust with
the Secretary of State of Delaware on May 8, 1998, and (2) executing a
declaration of trust, which was also signed by the Delaware trustee.
 
The trust's business and affairs are conducted by its trustees, which initially
are Harris Trust and Savings Bank, as property trustee, Wilmington Trust
Company, as Delaware trustee, and three administrative trustees. The
administrative trustees will be employees or officers of, or will be affiliated
with, Foster Wheeler. See "Description of Preferred Securities" beginning on
page 20 of the accompanying prospectus for further information. Harris Trust and
Savings Bank will also act as trustee under the guarantee. See "Description of
Guarantees" beginning on page 29 of the accompanying prospectus for further
information.
 
Foster Wheeler will have the right to appoint, remove and replace the property
trustee and the Delaware trustee. In certain cases, which are described under
"Description of Preferred Securities" on page 20 of the accompanying prospectus,
the holders of a majority in liquidation amount of the preferred securities will
also have this right. However, only Foster Wheeler will be entitled to appoint,
remove and replace the administrative trustees.
 
Foster Wheeler will pay all fees and expenses related to the trust and the
offering of the preferred securities. Foster Wheeler will also pay, directly or
indirectly, all ongoing costs, expenses and liabilities of the trust, except
obligations to make distributions and other payments on the common and preferred
securities.
 
The trust is being established for the following purposes only:
 
- - to issue and sell the common and preferred securities;
 
- - to use the proceeds from the sale of the common and preferred securities to
  acquire the junior subordinated debentures; and
 
- - to engage in activities that are directly related to these activities, such as
  registering the transfer of the preferred securities.
 
Because the trust is being established only for the purposes listed above, the
junior subordinated debentures will be the sole assets of the trust, and
payments under the junior subordinated debentures will be the sole source of
income to the trust.
 
All of the common securities of the trust will be owned by Foster Wheeler. The
common securities will rank equally with the preferred securities and payments
on the common securities will be made pro rata with the preferred securities,
unless Foster Wheeler fails to pay amounts that become due under the junior
subordinated debentures and under certain other circumstances described in
"Description of Debt Securities -- Events of Default -- Events of Default under
the Junior Subordinated Indenture" beginning on page 12 of the accompanying
prospectus. If Foster Wheeler fails to pay these amounts, the trust will be
unable to make payments under the common securities until it satisfies its
obligations under the preferred securities. See "Certain Terms of the Preferred
Securities -- Subordination of Common Securities" on page S-26 for further
details. Foster Wheeler will acquire common securities in total liquidation
amount equal to approximately 3% of the total capital of the trust.
 
The executive office of the trust is c/o Foster Wheeler Corporation, Perryville
Corporate Park, Clinton, New Jersey 08809, Attention: Office of the Secretary,
and its telephone number is (908) 730-4000.
 
We anticipate that the trust will not be required to file reports with the
Securities and Exchange Commission under the Securities Exchange Act of 1934, as
amended.

<PAGE>   22
 
                                USE OF PROCEEDS
 
The trust will invest all of the proceeds from the sale of the preferred
securities in the junior subordinated debentures. Foster Wheeler will use the
net proceeds from the sale of the junior subordinated debentures to pay
indebtedness it owes under a revolving credit agreement (the "Revolving Credit
Agreement"). This Revolving Credit Agreement matures on June 27, 2001, and bears
interest at a floating rate.
 
                              ACCOUNTING TREATMENT
 
For financial reporting purposes, the trust will be treated as a subsidiary of
Foster Wheeler, and its accounts will be included in Foster Wheeler's financial
statements.
 
In its future financial reports, Foster Wheeler will:
 
- - present the capital or preferred securities issued by the trust and any other
  trusts of Foster Wheeler on Foster Wheeler's balance sheet as a separate line
  term entitled "Mandatorily Redeemable Preferred Securities of Subsidiary
  Trusts Holding Solely Junior Subordinated Deferrable Interest Debentures",
 
- - include a footnote in its financial statements stating that the sole assets of
  these trusts are the junior subordinated debentures (specifying for each trust
  the principal amount, interest rate and maturity date of the junior
  subordinated debentures it holds) and providing information about the
  preferred securities and the guarantee, and
 
- - record distributions due on the preferred securities as charges to income in
  its consolidated statements of income.
 
Please see "Relationship Among the Preferred Securities, the Corresponding
Junior Subordinated Debentures, the Guarantees and the Expense Agreements' "
beginning on page 32 of the accompanying prospectus for further details.
 
                           DESCRIPTION OF SECURITIES
 
This prospectus supplement summarizes the specific terms and provisions of the
preferred securities, the junior subordinated debentures and the guarantee, and
supplements the general description of the terms and provisions of these
securities in the accompanying prospectus. These summaries are not meant to be
complete descriptions of each security. However, this prospectus supplement and
the accompanying prospectus do contain the material terms and conditions for
each security. For more information, please refer to the declaration of trust,
the junior subordinated indenture and the guarantee. Forms of these documents
are filed as exhibits to the registration statement of which this prospectus
supplement and the accompanying prospectus are a part. All terms used in this
prospectus supplement and not defined in this prospectus supplement have the
meanings given to them in these documents.
 
                   CERTAIN TERMS OF THE PREFERRED SECURITIES
 
DISTRIBUTIONS
 
The preferred securities represent undivided beneficial interests in the assets
of the trust. The only assets of the trust will be the junior subordinated
debentures. Distributions on the preferred securities are cumulative and will
accrue from the date they are first issued at the annual rate of   %.
Distributions will be payable quarterly in arrears on   ,   ,   and   of each
year, beginning           , 1999. Distributions not paid when due will
themselves accrue interest, at the annual rate of   % on the amount of unpaid
distributions
 
                                      S-22
<PAGE>   23
 
(to the extent permitted by law). When we refer to any payment of distributions,
the term "distributions" includes any such additional interest. The amount of
distributions payable for any period will be computed on the basis of a 360-day
year comprised of twelve 30-day months. The amount of interest payable for any
period shorter than a full quarterly period will be computed on the basis of the
actual number of days elapsed per 30-day month.
 
If distributions are payable on a date that is not a business day (as defined at
the end of this paragraph), payment will be made on the next business day (and
without any interest or other payment in respect of such delay). However, if the
next business day is in the next calendar year, payment of distributions will be
made on the preceding business day. A "business day" means each day except
Saturday, Sunday and any day on which banking institutions in The City of New
York or Chicago, Illinois are authorized or required by law to close.
 
Distributions on the preferred securities will only be paid if the trust has
sufficient funds available to make such payments. The income of the trust
available for the payment of distributions will be limited to payments made by
Foster Wheeler on the junior subordinated debentures.
 
DEFERRAL OF DISTRIBUTIONS
 
If no event of default has occurred and is continuing under the junior
subordinated debentures, Foster Wheeler can, on one or more occasions, defer
interest payments on the junior subordinated debentures for up to 20 consecutive
quarterly periods. A deferral of interest payments cannot extend, however,
beyond the maturity date of the junior subordinated debentures. If Foster
Wheeler defers interest payments on the junior subordinated debentures, the
trust will also defer quarterly distributions on the preferred securities.
During a deferral period, the amount of distributions due to you would continue
to accrue and such deferred distributions will themselves accrue interest.
 
Once Foster Wheeler makes all deferred interest payments on the junior
subordinated debentures, with accrued interest, it can again defer interest
payments on the junior subordinated debentures if no event of default under the
junior subordinated debentures has occurred and is continuing.
 
Foster Wheeler does not currently intend to defer interest payments on the
junior subordinated debentures. However, if Foster Wheeler does defer such
interest payments, it will be subject to certain restrictions relating to the
payment of dividends on or purchases of its capital stock and payments on its
debt securities that rank equal with or junior to the junior subordinated
debentures or the guarantee, as the case may be. See "Certain Terms of the
Junior Subordinated Debentures and Guarantee -- Option to Defer Interest
Payments" on pages S-29 and S-30.
 
If Foster Wheeler chooses to defer payments of interest on the junior
subordinated debentures, the preferred securities would at that time be treated
as being issued with original issue discount for United States federal income
tax purposes. This means you will be required to recognize and include interest
income with respect to the distributions (even if they are deferred) for United
States federal income tax purposes before you receive cash distributions. This
treatment will apply as long as you own preferred securities. See "United States
Federal Income Tax Consequences -- Interest Income and Original Issue Discount"
on page S-32.
 
PAYMENT OF DISTRIBUTIONS
 
Distributions on the preferred securities will be payable to holders named on
the securities register of the trust on the relevant record date. Payments on
the preferred securities represented by a global security will be made in
immediately available funds to DTC, the depositary for the preferred securities.
 
As long as the preferred securities are only in book-entry form, the record date
for the payment of distributions will be one business day before the
distribution date. If the preferred securities are ever issued in certificated
form,
 
                                      S-23
<PAGE>   24
 
the record date for the payment of distributions will be determined by the
administrative trustees and will be at least one business day before the
relevant payment dates.
 
REDEMPTION
 
Foster Wheeler may redeem the junior subordinated debentures before their
maturity:
 
- - on one or more occasions any time on or after              , 2004; and
 
- - before                   , 2004, if certain changes in tax or investment
  company law occur (each of which is a "Special Event" and is described more
  fully under "-- Special Event Redemption" on pages S-24 and S-25) provided
  that Foster Wheeler chooses to redeem within 90 days of the Special Event.
 
If Foster Wheeler chooses to redeem the junior subordinated debentures after a
Special Event, it must redeem them all.
 
When Foster Wheeler pays off the junior subordinated debentures, either at
maturity on              , 2029 or upon early redemption (as we discussed
above), the trust will use the cash it receives upon the redemption of the
junior subordinated debentures to redeem a like amount of the preferred and
common securities. The preferred and common securities will be redeemed at a
price equal to the redemption price for each $25 principal amount of the junior
subordinated debentures redeemed. The redemption price for the junior
subordinated debentures is 100% of their principal amount plus accrued and
unpaid interest to the date of redemption.
 
If less than all the preferred and common securities are redeemed, then the
aggregate liquidation amount of preferred and common securities to be redeemed
will be allocated pro rata among the preferred and common securities, subject to
the exceptions described under "-- Subordination of Common Securities" on page
S-26. The preferred securities to be redeemed will be selected by DTC in
accordance with its usual procedures if they are in book-entry-only form.
 
SPECIAL EVENT REDEMPTION
 
If a Tax Event or an Investment Company Event (as we define them below) has
occurred and is continuing, Foster Wheeler may redeem the junior subordinated
debentures, within 90 days following the occurrence of the Special Event.
 
"Tax Event" means that the trust or Foster Wheeler has received an opinion of an
independent tax counsel experienced in such matters to the effect that, as a
result of any:
 
- - amendment to, clarification of, or change (including any announced future
  change) in, the laws, the regulations interpreting such laws, or the official
  position of the United States or any political subdivision or taxing authority
  affecting taxation; or
 
- - official administrative pronouncement, notice, announcement or judicial
  decision interpreting or applying such laws or regulations;
 
where such change, amendment, pronouncement, notice, announcement or decision
becomes effective or is announced on or after the date of this prospectus
supplement, there is a substantial risk that:
 
- - the trust will be subject to United States federal income tax with respect to
  interest accrued or received on the junior subordinated debentures;
 
- - interest payable to the trust on the junior subordinated debentures when paid
  will not be deductible by Foster Wheeler for United States federal income tax
  purposes; or
 
- - the trust will be subject to more than a nominal amount of other taxes,
  duties, assessments or other governmental charges.
 
Foster Wheeler understands that the IRS recently challenged another company's
deduction for interest paid on a debt instrument similar in some respects to the
junior subordinated debentures and issued to an entity similar to the trust.
Based on available information, Foster Wheeler and the trust do not believe that
this challenge will affect Foster Wheeler's ability to deduct interest payments
on the junior subordinated debentures. However, you should
 
                                      S-24
<PAGE>   25
 
be aware that a Tax Court decision in that case in favor of the IRS, or other
unrelated developments, could cause a Tax Event. See "United States Federal
Income Tax Consequences" starting on page S-30. Laws and regulations have also
been proposed in the past which, if adopted retroactively, could also cause a
Tax Event, although such legislation and regulations are not currently pending.
 
"Investment Company Event" means the trust has received an opinion of a
nationally recognized independent counsel to the effect that, as a result of the
occurrence of a change in law or regulation or a written change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, the trust is or will be
considered an "investment company" under the Investment Company Act of 1940 that
is required to be registered under this law, which change becomes effective on
or after the date of this prospectus supplement.
 
If Foster Wheeler does not elect any of the options we described above, the
preferred securities will remain outstanding until the repayment of the junior
subordinated debentures.
 
REDEMPTION PROCEDURES
 
The trust will give you at least 30 days', but not more than 60 days', notice
before any redemption of preferred securities. To the extent funds are available
for payment, the trust will irrevocably deposit with the depositary sufficient
funds to pay the redemption amount for the preferred securities being redeemed.
The trust will also give the depositary irrevocable instructions and authority
to pay the redemption amount to the preferred securities holders. Distributions
to be paid on or before the redemption date for any preferred securities called
for redemption will be payable to the holders on the record dates for the
related dates of distribution.
 
Once notice of redemption is given and the redemption amount is irrevocably
deposited, additional distributions on the preferred securities will cease to
accrue and all rights of the holders of the preferred securities called for
redemption will cease, except for the right of holders to receive distributions
payable prior to the redemption date and the redemption amount, which amount
includes all accrued and unpaid distributions to the date of redemption (but
without interest on such redemption amount).
 
If any redemption date is not a business day, then the redemption amount will be
payable on the next business day (and without any interest or other payment in
respect of any such delay). However, if the next business day is in the next
calendar year, the redemption amount will be payable on the preceding business
day.
 
If payment of the redemption amount for any preferred securities called for
redemption is improperly withheld or refused and not paid either by the trust or
by Foster Wheeler pursuant to the guarantee, distributions on the preferred
securities will continue to accrue at the applicable rate from the originally
scheduled redemption date to the actual date of payment. In this case, the
actual payment date will be the redemption date for purposes of calculating the
redemption amount.
 
In compliance with applicable law (including the United States federal
securities laws), Foster Wheeler or its affiliates may, at any time, purchase
outstanding preferred securities by tender, in the open market, or by private
agreement.
 
OPTIONAL LIQUIDATION OF THE TRUST AND DISTRIBUTION OF JUNIOR SUBORDINATED
DEBENTURES
 
Foster Wheeler may dissolve the trust at any time, and, after paying the
creditors of the trust, cause the junior subordinated debentures to be exchanged
for the preferred securities.
 
Assuming that the trust is not taxable as a corporation, a distribution of
junior subordinated debentures upon a liquidation of the trust should not be a
taxable event to holders of the preferred securities. If, however, the trust
were subject to United States federal income tax with respect to income accrued
or received on the junior subordinated debentures, the distribution of junior
subordinated debentures by the
 
                                      S-25
<PAGE>   26
 
trust would be a taxable event to the trust and you. For further information,
see "United States Federal Income Tax Consequences -- Distribution of Junior
Subordinated Debentures to Beneficial Owners" beginning on page S-32.
 
If Foster Wheeler elects to dissolve the trust, thus causing the junior
subordinated debentures to be distributed in exchange for the preferred
securities, Foster Wheeler will continue to have the right to shorten the
maturity of the junior subordinated debentures, or to redeem the junior
subordinated debentures in certain circumstances. See "Certain Terms of the
Junior Subordinated Debentures and Guarantee -- Redemption" on page S-29 for
more information.
 
SUBORDINATION OF COMMON SECURITIES
 
Payment of distributions on, and the redemption and liquidation amount of, the
preferred and common securities will be made pro rata based on the aggregate
liquidation amounts of the preferred and common securities. However, if an event
of default has occurred and is continuing with respect to the junior
subordinated debentures, no payments may be made on the common securities unless
all unpaid amounts on the preferred securities have been provided for or paid in
full.
 
BOOK-ENTRY-ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
The preferred securities will be represented by one or more global securities
that will be deposited with and registered in the name of DTC or its nominee.
This means that the trust will not issue certificates to you for the preferred
securities. Each global security will be issued to DTC which will keep a
computerized record of its participants (for example, a broker) whose clients
have purchased the preferred securities. Each participant will then keep a
record of its clients. Unless it is exchanged in whole or in part for a
certificated security, a global security may not be transferred. However, DTC,
its nominees and their successors may transfer a global security as a whole to
one another.
 
Beneficial interests in a global security will be shown on, and transfers of the
global security will be made only through, records maintained by DTC and its
participants. DTC has provided the trust and Foster Wheeler with the following
information: 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 United States Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered under the provisions of Section 17A of the
Securities Exchange Act of 1934. DTC holds securities that its participants
("direct participants") deposit with DTC. DTC also records the settlement among
direct participants of securities transactions, such as transfers and pledges,
in deposited securities through computerized records for direct participant's
accounts. This eliminates the need to exchange certificates. Direct participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations.
 
DTC's book-entry system is also used by other organizations such as securities
brokers and dealers, banks and trust companies that work through a direct
participant. The rules that apply to DTC and its participants are on file with
the SEC.
 
DTC is owned by a number of its direct participants and by the NYSE, the
American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc.
 
When you purchase preferred securities through the DTC system, the purchases
must be made by or through a direct participant, who will receive credit for the
preferred securities on DTC's records. Since you actually own the preferred
security, you are the beneficial owner. Your ownership interest will only be
recorded on the direct (or indirect) participants' records. DTC has no knowledge
of your individual ownership of the preferred securities. DTC's records only
show the identity of the direct participants and the amount of the preferred
securities held by or through them. You will not
 
                                      S-26
<PAGE>   27
 
receive a written confirmation of your purchase or sale or any periodic account
statement directly from DTC. You should instead receive these from your direct
(or indirect) participant. As a result, the direct (or indirect) participants
are responsible for keeping accurate account of the holdings of their customers
like you.
 
The property trustee will wire payments on the preferred securities to DTC's
nominee. Foster Wheeler, the trust and the property trustee will treat DTC's
nominee as the owner of each global security for all purposes. Accordingly,
Foster Wheeler, the trust, the property trustee and any paying agent will have
no direct responsibility or liability to pay amounts due on the global security
to you or any other beneficial owners in the global security.
 
Any redemption notices will be sent by Foster Wheeler and the trust directly to
DTC, who will in turn inform the direct participants, who will then contact you
as a beneficial holder. If less than all of the preferred securities are being
redeemed, DTC's practice is to choose by lot the amount of the interest of each
direct participant to be redeemed. The direct participant will then use an
appropriate method to allocate the redemption among its beneficial holders, like
you.
 
It is DTC's current practice, upon receipt of any payment of distributions or
liquidation amount, to credit direct participants' accounts on the payment date
based on their holdings of beneficial interests in the global securities as
shown on DTC's records. In addition, it is DTC's current practice to assign any
consenting or voting rights to direct participants whose accounts are credited
with preferred securities on a record date, by using an omnibus proxy. Payments
by participants to owners of beneficial interests in the global securities, and
voting by participants, will be based on the customary practices between the
participants and owners of beneficial interests, as is the case with preferred
securities held for the account of customers registered in "street name."
However, payments will be the responsibility of the participants and not of DTC,
the property trustee, Foster Wheeler or the trust.
 
Preferred securities represented by a global security will be exchangeable for
certificated securities with the same terms in authorized denominations only if:
 
- - DTC is unwilling or unable to continue as depositary or if DTC ceases to be a
  clearing agency registered under applicable law and a successor depositary is
  not appointed by the trust within 90 days; or
 
- - the trust decides to discontinue use of the system of book-entry transfer
  through DTC (or any successor depositary).
 
If the book-entry-only system is discontinued, the property trustee will keep
the registration books for the preferred securities at its corporate office and
follow the practices and procedures discussed immediately below.
 
CERTIFICATED SECURITIES -- REGISTRATION, TRANSFER AND PAYMENT
 
If the trust issues certificated securities, each one will be registered in the
name of the relevant securityholder. The preferred securities may be transferred
or exchanged, based on administrative procedures in the declaration of trust,
without the payment of any service charge (other than any tax or other
governmental charge) by contacting the property trustee, Harris Trust and
Savings Bank, 311 West Monroe Street, 12th Floor, Chicago, Illinois 60606,
Attention: Corporate Trust Dept.
 
Distribution payments on certificated preferred securities will be made by
check. Payment of the redemption price or liquidation amount will be made in
immediately available funds when you surrender a preferred security.
 
                                      S-27
<PAGE>   28
 
                    CERTAIN TERMS OF THE JUNIOR SUBORDINATED
                            DEBENTURES AND GUARANTEE
 
The junior subordinated debentures will be issued pursuant to a supplemental
junior subordinated indenture ("supplemental junior subordinated indenture") to
the junior subordinated indenture.
 
Foster Wheeler will fully and unconditionally guarantee the payment of principal
and interest on the junior subordinated debentures under the guarantee on a
subordinated basis. See "-- Subordination" below for an explanation of the
subordination provisions.
 
SUBORDINATION
 
The junior subordinated debentures are unsecured and are junior in right of
payment to all senior indebtedness (as we define below) of Foster Wheeler. The
guarantee is unsecured and junior in right of payment to all senior indebtedness
of Foster Wheeler. This means that no payment on the junior subordinated
debentures and no payment under the guarantee may be made if:
 
- - any senior indebtedness of Foster Wheeler is not paid when due; or
 
- - if the maturity of any senior indebtedness of Foster Wheeler has been
  accelerated because of a default.
 
On any distribution of assets of Foster Wheeler to creditors as a result of any
dissolution, winding-up, liquidation or reorganization, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
principal of, premium, if any, and interest due or to become due on, all senior
indebtedness of Foster Wheeler must be paid in full before the holders of the
junior subordinated debentures or the guarantee are entitled to receive or
retain any payment.
 
Senior indebtedness means principal, premium and interest Foster Wheeler owes
on:
 
- - indebtedness for money borrowed by Foster Wheeler; or
 
- - indebtedness evidenced by securities, debentures, bonds or similar instruments
  issued by Foster Wheeler;
 
- - all capital lease obligations of Foster Wheeler;
 
- - all obligations of Foster Wheeler issued or assumed as the deferred purchase
  price of property;
 
- - all obligations of Foster Wheeler for reimbursement on any letter of credit,
  banker's acceptance, or similar facility;
 
- - all obligations of Foster Wheeler for claims in respect of derivative
  products, including interest rate, foreign exchange rate and other commodity
  forward contracts, options and swaps and other similar arrangements; and
 
- - all obligations of the type referred to in the bullet points above of other
  persons for the payment of which Foster Wheeler is responsible or liable as
  obligor, guarantor or otherwise.
 
The preferred securities, the junior subordinated debentures and the guarantee
do not limit the ability of Foster Wheeler and its subsidiaries to incur
additional indebtedness, including indebtedness that ranks senior in priority of
payment to the junior subordinated debentures and the guarantee. At September
25, 1998, on a pro forma basis, the total amount of senior indebtedness of
Foster Wheeler that would have effectively ranked senior to the junior
subordinated debentures and the guarantee would have been approximately $1,069.8
million.
 
INTEREST RATE AND MATURITY
 
The junior subordinated debentures will mature on                , 2029 and will
bear interest at the annual rate of      %, payable quarterly in arrears on
       ,        ,        and        of each year, beginning                ,
1999. Interest payments not paid when due will themselves accrue additional
interest at the annual rate of      % on the amount of unpaid interest (to the
extent
 
                                      S-28
<PAGE>   29
 
permitted by law). When we refer to any payment of interest on the junior
subordinated debentures, such interest includes such additional interest and any
Additional Sums as we define it in the next paragraph. The amount of interest
payable for any period will be computed based on a 360-day year comprised of
twelve 30-day months. The amount of interest payable for any period shorter than
a full quarterly period will be computed on the basis of the actual number of
days elapsed per 30-day month. The interest payment provisions for the junior
subordinated debentures correspond to the distribution provisions of the
preferred securities. The junior subordinated debentures do not have a sinking
fund. This means that Foster Wheeler is not required to make any principal
payments prior to maturity.
 
ADDITIONAL SUMS
 
If the trust is required to pay any taxes, duties, assessments or governmental
charges of whatever nature (other than withholding taxes) imposed by the United
States, or any other taxing authority (collectively, "Taxes"), then Foster
Wheeler will be required to pay additional sums ("Additional Sums") on the
junior subordinated debentures. The amount of any Additional Sums will be an
amount sufficient so that after the trust pays any Taxes, the trust will be in
the same position it would have been if it did not have to pay such Taxes.
 
REDEMPTION
 
Foster Wheeler has the option to redeem some or all of the junior subordinated
debentures before their maturity. See "Certain Terms of the Preferred
Securities -- Redemption" on page S-24 for further information.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES
 
If the property trustee distributes the junior subordinated debentures to the
preferred and common securities holders upon the dissolution and liquidation of
the trust, the junior subordinated debentures will be issued in denominations of
$25 principal amount and integral multiples thereof. Foster Wheeler anticipates
that the junior subordinated debentures would be distributed in the form of one
or more global securities and DTC, or any successor depositary for the preferred
securities, would act as depositary for the junior subordinated debentures and
guarantee. The depository arrangements for the junior subordinated debentures
would be substantially similar to those in effect for the preferred securities.
 
For a description of DTC and the terms of the depository arrangements relating
to payments, transfers, voting rights, redemption and other notices and other
matters, see "Certain Terms of the Preferred Securities -- Book-Entry-Only
Issuance -- The Depository Trust Company" beginning on page S-26.
 
OPTION TO DEFER INTEREST PAYMENTS
 
Foster Wheeler can defer interest payments on the junior subordinated debentures
for up to 20 consecutive quarterly periods, if no event of default has occurred
and is continuing with respect to the junior subordinated debentures. A deferral
of interest payments cannot extend, however, beyond the maturity date of the
junior subordinated debentures. No interest will be due and payable on the
junior subordinated debentures until the end of the deferral period except upon
a redemption of the junior subordinated debentures during a deferral period.
 
Foster Wheeler may pay at any time all or any portion of the interest accrued to
that point during a deferral period. At the end of the deferral period or at a
redemption date, Foster Wheeler will be obligated to pay all accrued and unpaid
interest.
 
Once Foster Wheeler makes all interest payments on the junior subordinated
debentures, with accrued and unpaid interest, it can again defer interest
payments on the junior subordinated debentures if no event of default under the
junior subordinated debentures has occurred and is continuing.
 
During any deferral period, Foster Wheeler will not be permitted to:
 
- - declare or pay any dividend on, make any distributions, or redeem, purchase,
  acquire or
 
                                      S-29
<PAGE>   30
 
  make a liquidation payment on any shares of its capital stock; or
 
- - make any payment of principal, premium, if any, or interest, on or repay,
  repurchase or redeem any debt securities issued by Foster Wheeler that rank
  equal with or junior to the junior subordinated debentures; or
 
- - make any guarantee payment with respect to any guarantee by Foster Wheeler of
  debt securities of any of its subsidiaries, if the guarantee ranks equal to,
  or junior in right of payment to the junior subordinated debentures, other
  than:
 
- - dividends or distributions by Foster Wheeler by way of issuance of its capital
  stock;
 
- - payments under the guarantee by Foster Wheeler in respect of the preferred and
  common securities;
 
- - any declaration of a dividend in connection with the implementation of a
  shareholders' rights plan, or the issuing of stock under such a plan; and
 
- - purchase of common stock relating to the issuing of common stock or rights
  under any of Foster Wheeler's benefit plans.
 
If the property trustee is the sole holder of the junior subordinated
debentures, Foster Wheeler will give the trust, the administrative trustees and
the property trustee notice if it decides to defer interest payments on the
junior subordinated debentures. Foster Wheeler will give that notice one
business day before the earlier of:
 
- - the next date distributions on the preferred securities are payable; or
 
- - the date the trust is required to give notice to the NYSE (or any other
  applicable self-regulatory organization) or to holders of the preferred
  securities of the record date or the date any distribution is payable.
 
The administrative trustees will give notice to the holders of preferred
securities if Foster Wheeler decides to defer interest payments on the junior
subordinated debentures.
 
If the property trustee is not the sole holder of the junior subordinated
debentures, Foster Wheeler will give the holders notice of its selection of any
deferral period ten business days prior to the earlier of:
 
- - the next interest payment date; or
 
- - the date upon which Foster Wheeler is required to give notice to the NYSE (or
  any other applicable self-regulatory organization) or to holders of the junior
  subordinated debentures of the record date or payment date of any related
  interest payment.
 
                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
In the opinion of White & Case LLP, special tax counsel to Foster Wheeler and
the trust, the following is a description of the principal United States federal
income tax consequences of purchasing, holding and selling the preferred
securities. This description is based on (1) the Internal Revenue Code of 1986,
as amended (the "Code"), (2) income tax regulations (proposed and final) issued
under the Code, and (3) administrative and judicial interpretations of the Code
and regulations, each as in effect and available as of the date of this
prospectus supplement. These income tax laws, regulations, and interpretations,
however, may change at any time, and any change could be retroactive to the
issuance date of the preferred securities. In particular, legislation has been
proposed in the past that could adversely affect Foster Wheeler's ability to
deduct interest on the junior subordinated debentures, which may in turn permit
Foster Wheeler to cause a redemption of the preferred securities prior to
               , 2004. See "-- Potential Changes in Tax Law or Interpretation"
beginning on page S-33. However, no such legislation currently is pending.
 
These income tax laws and regulations are also subject to various
interpretations, and the Internal Revenue Service (the "IRS") or the
 
                                      S-30
<PAGE>   31
 
courts could later disagree with the explanations or conclusions contained in
this summary. The IRS has not formally ruled (and we do not intend to seek a
ruling) on the tax consequences of purchasing, holding and selling the preferred
securities. Accordingly, the IRS could challenge the opinions expressed in this
prospectus supplement concerning such consequences, and a court could agree with
the IRS.
 
Except where we state otherwise, this summary deals only with preferred
securities held as capital assets (as defined in the Code) by a holder who (1)
purchases the preferred securities at their original offering price and (2) is a
U.S. Holder (as defined below).
 
A "U.S. Holder" is a preferred securities holder who or which for United States
federal income tax purposes is:
 
- - a United States citizen or resident individual;
 
- - a corporation or partnership created or organized in or under the laws of the
  United States;
 
- - an estate if its income is subject to United States federal income taxation
  regardless of its source;
 
- - a trust if such trust validly has elected to be treated as a United States
  person for United States federal income tax purposes, or if (1) a United
  States court can exercise primary supervision over its administration and (2)
  one or more United States persons have the authority to control all of its
  substantial decisions; or
 
- - any other person who is otherwise taxable with respect to income from the
  preferred securities on a net income basis.
 
We do not address all of the tax consequences that may be relevant to a U.S.
Holder. We also do not address, except as stated below, any of the tax
consequences to (1) holders that are not U.S. Holders (as defined below), (2)
holders that may be subject to special tax treatment such as financial
institutions, thrift institutions, real estate investment trusts, tax-exempt
organizations, regulated investment companies, insurance companies and brokers
and dealers or traders in securities or currencies, (3) persons whose functional
currency is not the United States dollar and (4) persons that will hold
preferred securities as part of a position in a straddle or as part of a
hedging, conversion or other integrated investment transaction. Further, we do
not address:
 
- - the United States federal estate and gift or alternative minimum tax
  consequences of the purchase, ownership or sale of the preferred securities;
  or
 
- - any state, local or foreign tax consequences of the purchase, ownership and
  sale of preferred securities.
 
PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT WITH THEIR OWN TAX ADVISORS IN
LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES AS TO THE UNITED STATES FEDERAL
INCOME TAX CONSEQUENCES OF PURCHASING, HOLDING AND DISPOSING OF THE PREFERRED
SECURITIES, AS WELL AS THE EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
CHARACTERIZATION OF THE TRUST
 
Under current law and assuming compliance with the terms of the declaration of
trust, the underwriting agreement and the junior subordinated indenture (and
other relevant documents), the trust will not be taxable as a corporation for
United States federal income tax purposes. As a result, you will include in your
gross income for United States federal income tax purposes all interest,
including original issue discount, paid or accrued with respect to your pro rata
share of the assets of the trust, including the junior subordinated debentures,
whether or not cash is actually distributed to you. See "-- Interest Income and
Original Issue Discount" on page S-32.
 
CHARACTERIZATION OF THE JUNIOR
SUBORDINATED DEBENTURES
 
Foster Wheeler intends to take the position that the junior subordinated
debentures will be classified for United States federal income tax purposes as
its own indebtedness under current law and, by acceptance of a preferred
security, you agree to treat the junior subordinated debentures as indebtedness
for all United States
 
                                      S-31
<PAGE>   32
 
federal tax purposes. The remainder of this description assumes that the junior
subordinated debentures will be classified as indebtedness of Foster Wheeler.
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
In general, a debt instrument will have original issue discount ("OID") equal to
the excess of its "stated redemption price at maturity" over its "issue price."
The issue price of the junior subordinated debentures will be the initial
offering price of a substantial amount of the preferred securities to investors
(other than persons acting in their capacity as underwriters, placement agents
or wholesalers). An instrument's "stated redemption price at maturity" is equal
to the sum of all amounts payable as interest and principal on the instrument,
excluding only "qualified stated interest." Under the Treasury Regulations
addressing original issue discount (the "OID Regulations"), a remote contingency
that stated interest will not be timely paid is ignored in determining whether a
debt instrument is issued with OID. Foster Wheeler believes that the likelihood
of its exercising its option to defer payments of interest is remote.
Accordingly, all of the stated interest on the junior subordinated debentures
should be "qualified stated interest." Based on the foregoing, Foster Wheeler
believes that the stated redemption price at maturity of the junior subordinated
debentures will not exceed their issue price by more than a de minimis amount;
thus, the junior subordinated debentures will not be considered to be issued
with OID at the time of their original issuance. Accordingly, you should include
in gross income your allocable share of interest on the junior subordinated
debentures. The following discussion assumes that unless and until Foster
Wheeler exercises its option to defer interest on the junior subordinated
debentures, the junior subordinated debentures will not be treated as issued
with OID.
 
Under the OID Regulations, if Foster Wheeler exercised its option to defer any
payment of interest, the junior subordinated debentures would at that time be
treated as issued with OID, and all stated interest on the junior subordinated
debentures would thereafter be treated as OID as long as the junior subordinated
debentures remained outstanding. In such event, all of your taxable interest
income with respect to the junior subordinated debentures would be accounted for
as OID on an economic accrual basis regardless of your method of tax accounting,
and actual distributions of stated interest would not be reported as taxable
income. Consequently, you would be required to include in gross income OID even
though Foster Wheeler would not make any actual cash payments during periods in
which it exercised its option to defer cash payments.
 
The provision of the OID Regulations discussed above has not been addressed in
any rulings or other interpretations by the IRS, and it is possible that the IRS
could interpret such provision differently.
 
Subsequent uses of the term "interest" in this summary include income in the
form of OID.
 
CORPORATE U.S. HOLDERS
 
Because income on the preferred securities will constitute interest or OID,
corporate U.S. Holders will not be entitled to a dividends received deduction
with respect to any income recognized with respect to the preferred securities.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO BENEFICIAL OWNERS
 
Under certain circumstances, as described under "Certain Terms of the Preferred
Securities -- Optional Liquidation of the Trust and Distribution of Junior
Subordinated Debentures" beginning on page S-25, the trustee may distribute the
junior subordinated debentures to you in exchange for your preferred securities.
Under current law, such distribution will be non-taxable and will result in your
receiving directly your pro rata share of the junior subordinated debentures
previously held indirectly through the trust, with a holding period and
aggregate tax basis equal to the holding period and aggregate tax basis you had
in your preferred securities before such distribution. If, however,
 
                                      S-32
<PAGE>   33
 
the liquidation of the trust were to occur because the trust is subject to
United States federal income tax with respect to income accrued or received on
the junior subordinated debentures, the distribution of junior subordinated
debentures to you by the trust would be a taxable event to the trust and to you.
In such case, you would recognize gain or loss as if you had exchanged your
preferred securities for the junior subordinated debentures received upon the
liquidation of the trust. You will include interest in respect of junior
subordinated debentures received from the trust in the manner described above
under "-- Interest Income and Original Issue Discount" on page S-32.
 
SALE, EXCHANGE OR RETIREMENT OF PREFERRED SECURITIES
 
If you sell (including a redemption for cash) preferred securities, you will
recognize gain or loss equal to the difference between your adjusted tax basis
in the preferred securities and the amount realized on the sale of such
preferred securities. Assuming that Foster Wheeler does not exercise its option
to defer payment of interest on the junior subordinated debentures, your
adjusted tax basis in the preferred securities generally will be your initial
purchase price. If the junior subordinated debentures are deemed to be issued
with OID as a result of Foster Wheeler's deferral of any interest payment, your
adjusted tax basis in the preferred securities generally will be your initial
purchase price, increased by OID previously includible in your gross income to
the date of sale and decreased by distributions or other payments you received
on the preferred securities since and including the date of the first period in
which Foster Wheeler exercised its option to defer interest payments. Such gain
or loss generally will be a capital gain or loss (except to the extent any
amount realized is treated as a payment of accrued but unpaid interest (other
than OID) with respect to your pro rata share of the junior subordinated
debentures required to be included in income). If you are not a corporation and
your holding period for a preferred security exceeds one year, the maximum
United States federal income tax rate applicable to such gain will be lower than
the maximum United States federal income tax rate applicable to your ordinary
income.
 
Should Foster Wheeler exercise its option to defer any payment of interest on
the junior subordinated debentures, the preferred securities may trade at a
price that does not accurately reflect the value of accrued but unpaid interest
with respect to the underlying junior subordinated debentures. In the event of
such a deferral, if you dispose of preferred securities between record dates for
payments of distributions on such securities, you will be required to include in
income (as ordinary income) accrued but unpaid interest on the junior
subordinated debentures to the date of sale as OID, but you may not receive the
cash related to such unpaid interest. However, you would add such amount to your
adjusted tax basis in the preferred securities. To the extent the selling price
is less than your adjusted tax basis, you will recognize a capital loss. Subject
to certain limited exceptions, capital losses cannot be applied to offset
ordinary income for United States federal income tax purposes.
 
POTENTIAL CHANGES IN TAX LAW OR INTERPRETATION
 
Prospective investors should be aware that legislation has been introduced in
the United States Congress in the past that would, if enacted, deny an interest
deduction to issuers of instruments such as the junior subordinated debentures.
No such legislation is currently pending. There can be no assurance, however,
that similar legislation will not ultimately be enacted into law, or that other
developments will not occur after today that would adversely affect the tax
treatment of the junior subordinated debentures. Such a change could give rise
to a Tax Event, which may permit Foster Wheeler to cause a redemption of the
preferred securities, as described more fully in this prospectus supplement. See
"Certain Terms of the Preferred Securities -- Redemption" on page S-24.
 
Moreover, Foster Wheeler is aware of at least one case in which the IRS
attempted to disallow the deductibility of interest paid with respect to
subordinated debentures that were
 
                                      S-33
<PAGE>   34
 
issued to a partnership that, in turn, issued "monthly income preferred
securities" ("MIPs"). The issuer of such subordinated debentures recently
petitioned the Tax Court of the United States to challenge such proposed
disallowance. However, the subordinated debentures issued in such transaction
are distinguishable from the junior subordinated debentures and the MIPs issued
in such transaction are distinguishable from the preferred securities. It is
possible, though, that a decision by the Tax Court in such case could give rise
to a Tax Event, which may permit Foster Wheeler to cause a redemption of the
preferred securities, as described more fully in this prospectus supplement. See
"Certain Terms of Preferred Securities -- Redemption" on page S-24.
 
UNITED STATES BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
Certain noncorporate holders of preferred securities may be subject to backup
withholding at a rate of 31% on payments made on a preferred security. Backup
withholding will apply to you only if you are a United States person (as defined
in the Code) and you (1) fail to furnish your Taxpayer Identification Number
("TIN") which, in the case of an individual, would be your Social Security
number, (2) furnish an incorrect TIN, (3) are notified by the IRS that you have
failed to properly report payments of interest or dividends or (4) under certain
circumstances, fail to certify, under penalty of perjury, that you furnished a
correct TIN and have not been notified by the IRS that it is subject to backup
withholding. The amounts withheld under the backup withholding rules are not an
additional tax and may be refunded, or credited against your United States
federal income tax liability provided that the required information is furnished
to the IRS. Further, information reporting will apply to such payments.
 
THE ABOVE DESCRIPTION IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL
TAX CONSEQUENCES RELATING TO YOUR ACQUISITION, OWNERSHIP AND SALE OF PREFERRED
SECURITIES. ACCORDINGLY, PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS TO DETERMINE THE UNITED STATES FEDERAL, STATE, LOCAL AND FOREIGN
TAX CONSEQUENCES RELATING TO THE ACQUISITION, OWNERSHIP AND SALE OF PREFERRED
SECURITIES IN LIGHT OF THEIR PARTICULAR SITUATIONS.
 
                          CERTAIN ERISA CONSIDERATIONS
 
Each fiduciary of an employee benefit plan subject to Title I of ERISA, a plan
described in Section 4975 of the Code, including an individual retirement
arrangement or a Keogh plan, and any entity whose underlying assets include
"plan assets" by reason of any such employee benefit plan's or plan's investment
in such entity (each, a "Plan") should consider the fiduciary responsibility and
prohibited transaction provisions of ERISA and Section 4975 of the Code in the
context of the Plan's particular circumstances before authorizing an investment
in the preferred securities. Accordingly, such a fiduciary should consider,
among other factors, that each Plan investing in the preferred securities will
be deemed to have represented that the Plan's purchase and holding of the
preferred securities is covered by one or more specified prohibited transaction
class exemptions. Plan fiduciaries should also consider whether the Plan's
investment in the preferred securities would satisfy the prudence and
diversification requirements of ERISA and would be consistent with the documents
and instruments governing their Plan.
 
Section 406 of ERISA and Section 4975 of the Code prohibit Plans from engaging
in certain transactions involving "plan assets" with persons who are "parties in
interest" under ERISA or "disqualified persons" under the Code ("Parties in
Interest") with respect to such a Plan. A violation of these "prohibited
transaction" rules may result in an excise tax, penalty or other liabilities
under ERISA and/or Section 4975 of the Code for such persons, unless exemptive
relief is available under an applicable statutory or administrative exemption.
Employee benefit plans that are governmental plans (as defined in Section 3(32)
of ERISA), certain church plans
 
                                      S-34
<PAGE>   35
 
(as defined in Section 3(33) of ERISA or Section 4975(g)(2) of the Code) and
foreign plans (as described in Section 4(b)(4) of ERISA) are not subject to the
requirements of ERISA or Section 4975 of the Code.
 
Under a regulation (the "Plan Assets Regulation") issued by the United States
Department of Labor (the "DOL"), the assets of the trust would be deemed to be
"plan assets" of a Plan for purposes of ERISA and Section 4975 of the Code if
"plan assets" of the Plan were used to acquire an equity interest in the trust
and no exception were applicable under the Plan Assets Regulation. An "equity
interest" is defined under the Plan Assets Regulation as any interest in an
entity other than an instrument which is treated as indebtedness under
applicable local law and which has no substantial equity features. Under one
such exception contained in the Plan Assets Regulation, the assets of the trust
would not be deemed to be "plan assets" of investing Plans if, immediately after
the most recent acquisition of any equity interest in the trust, less than 25%
of the value of each class of equity interests in the trust were held by Plans,
other employee benefit plans not subject to ERISA or Section 4975 of the Code
(such as governmental, church or foreign plans), and entities holding assets
deemed to be "plan assets" of any Plan (collectively, "Benefit Plan Investors").
No assurance can be given that the value of the preferred securities held by
Benefit Plan Investors will be less than 25% of the total value of such
preferred securities at the completion of the initial offering or thereafter,
and no monitoring or other measures will be taken with respect to the
satisfaction of the conditions to this exception. All of the common securities
will be purchased and held by Foster Wheeler.
 
It is possible that the preferred securities may qualify as "publicly-offered
securities" under the Plan Assets Regulation. "Publicly-offered securities"
within the meaning of the Plan Assets Regulation are:
 
- - widely held (i.e., owned by more than 100 investors independent of Foster
  Wheeler and of each other);
 
- - freely transferable; and
 
- - sold as part of an offering pursuant to an effective registration statement
  under the Securities Act and then timely registered under Section 12(b) or
  12(g) of the Exchange Act.
 
If the preferred securities are "publicly-offered securities," the underlying
assets of the trust would not be deemed to be "plan assets" of investing Plans.
The Underwriter expects:
 
- - that the preferred securities will be held by at least 100 independent
  investors at the conclusion of the offering of the preferred securities;
 
- - that there will be no restrictions imposed on the transfer of the preferred
  securities; and
 
- - that the preferred securities will be sold as part of an offering pursuant to
  an effective registration statement under the Securities Act and then will be
  timely registered under the Exchange Act.
 
There can be no assurance that this or any of the other exceptions set forth in
the Plan Assets Regulation will apply to the preferred securities, and, as a
result, under the terms of the Plan Assets Regulation, an investing Plan's
assets could be considered to include an undivided interest in the assets held
by the trust (including the junior subordinated debentures), and transactions by
the trust could be subject to the fiduciary responsibility provisions of Title I
of ERISA.
 
Regardless of whether the assets of the trust are deemed to be "plan assets" of
Plans investing in the trust, as discussed above, the acquisition and holding of
the preferred securities with "plan assets" of a Plan could itself result in a
prohibited transaction. The DOL has issued five prohibited transaction class
exemptions ("PTCEs") that may provide exemptive relief for direct or indirect
prohibited transactions resulting from the purchase and/or holding of the
preferred securities by a Plan. These class exemptions are:
 
- - PTCE 96-23 (for certain transactions determined by "in-house asset managers");
 
                                      S-35
<PAGE>   36
 
- - PTCE 95-60 (for certain transactions involving insurance company general
  accounts);
 
- - PTCE 91-38 (for certain transactions involving bank collective investment
  funds);
 
- - PTCE 90-1 (for certain transactions involving insurance company pooled
  separate accounts); and
 
- - PTCE 84-14 (for certain transactions determined by independent "qualified
  professional asset managers").
 
Such class exemptions may not, however, apply to all of the transactions that
could be deemed prohibited transactions in connection with a Plan's investment
in the preferred securities.
 
Any purchaser of the preferred securities that is an insurance company using
assets of its general account should note that, based on the reasoning of the
United States Supreme Court in John Hancock Mutual Life Insurance Company v.
Harris Trust & Savings Bank, 114 S. Ct. 517 (1993), an insurance company's
general account may be deemed to include assets of Plans investing in such
general account (e.g., through the purchase of an annuity contract).
 
On December 22, 1997, the DOL issued proposed regulations (62 F.R. 66908) under
Section 401(c) of ERISA intended to provide guidance on which assets held by an
insurance company in its general account constitute "plan assets" in cases where
such insurer has issued, on or before December 31, 1998, policies or contracts
to or for the benefit of a Plan that are supported by assets of such insurer's
general account. When a Plan acquires such a policy or contract issued by an
insurer on or before December 31, 1998, which is supported by assets of the
insurer's general account, the underlying general account assets will not be
deemed to be assets of such Plan if the insurer satisfies the requirements of
such regulation (if adopted as proposed).
 
Section 401(c) of ERISA also provides for certain other temporary and
transitional rules concerning the application of the fiduciary responsibility
and prohibited transaction provisions of ERISA and Section 4975 of the Code to
assets of an insurer's general account that support insurance policies or
contracts issued by the insurer. The plan asset status of insurance company
separate accounts is unaffected by Section 401(c) of ERISA and the proposed
regulations thereunder. Any insurance company considering the use of its general
account assets to purchase preferred securities should consult with its counsel
concerning these and other matters affecting its purchase decision.
 
Because of ERISA's prohibitions and those of Section 4975 of the Code, discussed
above, the preferred securities, or any interest therein, may not be purchased
or held by any Plan or any person investing "plan assets" of any Plan, unless
such purchase and holding is covered by the exemptive relief available under
PTCE 96-23, 95-60, 91-38, 90-1 or 84-14. Accordingly, each purchaser or holder
of the preferred securities or any interest therein will be deemed to have
represented by its purchase and holding thereof that either:
 
- - it is not a Plan and no part of the assets to be used by it to purchase and/or
  hold such preferred securities or any interest therein constitutes "plan
  assets" of any Plan; or
 
- - it is itself a Plan, or is purchasing or holding the preferred securities or
  an interest therein on behalf of or with "plan assets" of one or more Plans,
  and each such purchase and holding of such securities satisfies the
  requirements of, and is entitled to full exemptive relief under, PTCE 96-23,
  95-60, 91-38, 90-1 or 84-14.
 
Although, as noted above, governmental plans are not subject to ERISA, including
the prohibited transaction provisions thereof, or of Section 4975 of the Code,
state laws or regulations governing the investment and management of the assets
of such plans may contain fiduciary and prohibited transaction provisions
similar to those under ERISA and Section 4975 of the Code discussed above.
Accordingly, fiduciaries of governmental plans, in consultation with their
advisors, should consider the impact of their respective state laws on their
investment in preferred securities,

and the considerations discussed above, to the extent applicable.
 
Due to the complexity of the fiduciary responsibility and prohibited transaction
rules described above and the penalties that may be imposed upon persons
involved in non-exempt prohibited transactions, it is particularly important
that fiduciaries or other persons considering purchasing the preferred
securities on behalf of or with "plan assets" of any Plan consult with their
counsel, prior to any such purchase, with respect to the potential applicability
of ERISA and Section 4975 of the Code to such investment and whether any
exemption would be applicable and determine on their own whether all conditions
of such exemption or exemptions have been satisfied such that the acquisition
and holding of preferred securities by the purchaser Plan are entitled to full
exemptive relief thereunder. Fiduciaries of non-ERISA plans should consult with
their counsel concerning any applicable state law considerations prior to any
such purchase.

                                  UNDERWRITING
 
GENERAL
 
Based on the terms and conditions of an underwriting agreement, the trust has
agreed to sell to each of the underwriters named below, and each of the
underwriters, for whom Lehman Brothers Inc., Bear, Stearns & Co. Inc., EVEREN
Securities, Inc., NationsBanc Montgomery Securities LLC, PaineWebber
Incorporated, Prudential Securities Incorporated and SG Cowen Securities
Corporation, are acting as the representatives, has severally agreed to purchase
from the trust, the number of preferred securities set forth opposite its name
below:

                                                                   NUMBER OF
UNDERWRITERS                                                  PREFERRED SECURITIES

<S>                                                           <C>
 
Total
</TABLE>
 
The underwriters are obligated to purchase all of the preferred securities, if
any preferred securities are purchased.
 
Foster Wheeler and the trust have agreed with the underwriters to indemnify them
against certain civil liabilities, including liabilities under the Securities
Act of 1933, or to contribute with respect to payments which the underwriters
may be required to make.
 
The underwriters have in the past and may in the future engage in transactions
with, or perform services for, Foster Wheeler or its subsidiaries in the
ordinary course of their businesses.
 
COMMISSIONS AND DISCOUNTS
 
The underwriters will offer the preferred securities directly to the public at
$25 per preferred security. The underwriters may also offer the preferred
securities to certain securities dealers at the above mentioned offering price
less a concession of $  per preferred security. The underwriters may allow, and
such dealers may reallow, a discount not in excess of $  per preferred security
to certain brokers and dealers. After the initial public offering, the public
offering price, concession and discount may be changed.
 
Since the proceeds from the sale of the preferred securities will be used to
purchase the junior subordinated debentures, Foster Wheeler has agreed to pay to
the underwriters an underwriting commission of $  per preferred security (or a
total of $  million).
 
The representatives have advised Foster Wheeler that they intend to make a
market in the preferred securities; however, they are not obligated to do so and
may discontinue market making at any time without notice. We can not give any
assurance about the liquidity of the trading market for the preferred
securities.
 
Foster Wheeler will pay certain expenses, expected to be approximately
$          associated with the offer and sale of the preferred securities.
 
OVER-ALLOTMENT OPTION
 
The underwriters have an option to purchase up to   additional preferred
securities at the public offering price to cover over-allotments. The
underwriters can exercise this option for a period of 30 days after the date of
this prospectus supplement. If the underwriters exer-
 
                                      S-38
<PAGE>   39
 
cise this option, each underwriter will have a firm commitment, subject to some
conditions, to purchase approximately the same percentage of any additional
preferred securities as the percentage of the preferred securities initially
offered that such underwriter has agreed to purchase.
 
NEW YORK STOCK EXCHANGE LISTING
 
Before this offering, there has been no established public trading market for
the preferred securities. The trust has submitted an application to list the
preferred securities on the NYSE. If approved for listing, trading of the
preferred securities is expected to begin within 30 days of the issuance of the
preferred securities. In order to meet all of the requirements for listing the
preferred securities on the NYSE, the underwriters have agreed to sell the
preferred securities to a minimum of 400 beneficial holders. The representatives
have advised Foster Wheeler that they intend to make a market in the preferred
securities prior to the commencement of trading on the NYSE. However, the
representatives are not obligated to do so and may discontinue market making at
any time without notice. We can not give any assurance about the liquidity of
the trading market for the preferred securities.
 
NO SALES OF SIMILAR SECURITIES
 
Foster Wheeler and the trust have agreed that for 30 business days after the
date of this prospectus supplement they will not directly or indirectly offer,
sell, offer to sell, grant any option for the sale of or otherwise dispose of
any preferred securities or junior subordinated debentures or any securities
convertible or exchangeable into, or exercisable for preferred securities or
junior subordinated debentures, or any debt securities substantially similar to
junior subordinated debentures or any equity securities substantially similar to
the preferred securities (except for the preferred securities and junior
subordinated debentures described in this prospectus supplement) without the
prior written consent of Lehman Brothers Inc.
 
PRICE STABILIZATION AND SHORT POSITIONS
 
In connection with the sale of the preferred securities, SEC rules permit the
underwriters to engage in transactions that stabilize the price of the preferred
securities. These transactions may include purchases for the purpose of fixing
or maintaining the price of the preferred securities.
 
The underwriters may create a short position in the preferred securities in
connection with the offering. That means they may sell a larger number of the
preferred securities than is shown on the cover page of the prospectus
supplement. If they create a short position, the underwriters may purchase
preferred securities in the open market to reduce the short position.
 
If the underwriters purchase the preferred securities to stabilize the price or
to reduce their short position, the price of the preferred securities could be
higher than it might be if they had not made such purchases. The underwriters
make no representation or prediction about any effect that the purchases may
have on the price of the preferred securities.
 
The underwriters may suspend any of these activities at any time.
 
The representatives of the underwriters may also impose a penalty bid on certain
underwriters and selling group members. This means that if the representatives
purchase preferred securities in the open market to reduce the underwriters'
short position or to stabilize the price of the preferred securities, they may
reclaim the amount of the selling concession from the underwriters or selling
group members who sold those securities as part of this offering.

     Foster Wheeler Corporation ("Foster Wheeler" or the "Corporation") may
offer from time to time, together or separately, up to $300,000,000 aggregate
principal amount, or its equivalent based on the applicable exchange rate at the
time of the offering, of its (i) debt securities consisting of debentures, notes
or other unsecured evidences of indebtedness (the "Debt Securities"), which may
be either senior debt securities (the "Senior Debt Securities"), senior
subordinated debt securities (the "Senior Subordinated Debt Securities") or
junior subordinated debt securities (the "Junior Subordinated Debentures"); (ii)
shares of preferred stock (the "Preferred Stock"), which may be issued in the
form of depositary receipts (the "Depositary Shares") that will represent a
fraction of a share of Preferred Stock; (iii) shares of common stock (the
"Common Stock") and (iv) warrants to purchase securities of the Corporation as
shall be designated by the Corporation at the time of the offering (the
"Warrants"), in each case in amounts, at prices and on terms to be determined at
the time of the offering. The Debt Securities, Preferred Stock, Depositary
Shares, Common Stock and the Warrants are collectively called the "Corporation
Securities."
 
     FW Preferred Capital Trust I and FW Preferred Capital Trust II, each a
statutory business trust organized under the laws of the State of Delaware
(each, an "Issuer Trust"), may severally offer, from time to time, preferred
securities (the "Preferred Securities") representing preferred undivided
beneficial interests in the assets of such Issuer Trust. The Corporation will
initially be the registered holder (the "Holder") of all the beneficial
interests represented by common securities of such Issuer Trust (the "Common
Securities" and, together with the Preferred Securities, the "Trust
Securities"). The Trust Securities and the Corporation Securities are referred
to collectively herein as the "Securities"). Holders of the Preferred Securities
will be entitled to receive preferential cumulative cash distributions
("Distributions") accumulating from the date of original issuance and payable
periodically as provided in the applicable supplement to this Prospectus (the
"Prospectus Supplement"). Concurrently with the issuance by an Issuer Trust of
its Preferred Securities, such Issuer Trust will invest the proceeds thereof and
of any contributions received in respect of the Common Securities in a
corresponding series of the Corporation's Junior Subordinated Debentures (the
"Corresponding Junior Subordinated Debentures") with terms corresponding to the
terms of that Issuer Trust's Preferred Securities (the "Related Preferred
Securities"). The Corresponding Junior Subordinated Debentures will be the sole
assets of such Issuer Trust, and payments under the Corresponding Junior
Subordinated Debentures will be the only revenues of such Issuer Trust. If so
provided in the applicable Prospectus Supplement, the Corporation may redeem the
Corresponding Junior Subordinated Debentures (and cause the redemption of the
Related Preferred Securities) or may dissolve each Issuer Trust and cause the
Corresponding Junior Subordinated Debentures to be distributed to the Holders of
the Related Preferred Securities in liquidation of their interests in such
Issuer Trust.

                             AVAILABLE INFORMATION
 
     The Corporation is subject to the informational requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in
accordance therewith files reports, proxy statements and other information with
the Securities and Exchange Commission (the "Commission"). Such reports, proxy
statements and other information concerning the Corporation can be inspected and
copied at the Commission's office at 450 Fifth Street, N.W., Room 1024,
Washington, D.C. 20549, and the Commission's Regional Offices in New York (Seven
World Trade Center, 13th Floor, New York, New York 10048) and Chicago (Citicorp
Center, 500 West Madison Street, Suite 1400, Chicago, Illinois 60661-2511).
Copies of such material can also be obtained at prescribed rates from the Public
Reference Section of the Commission at 450 Fifth Street, N.W., Washington, D.C.
20549. The Commission also maintains a site on the World Wide Web, the address
of which is http://www.sec.gov, that contains reports, proxy statements and
other information regarding issuers, such as the Corporation, that file
electronically with the Commission. In addition, such materials can be inspected
at the office of the New York Stock Exchange, Inc., on which certain securities
of the Corporation are listed. This Prospectus does not contain all the
information set forth in the registration statement of which this Prospectus
forms a part (the "Registration Statement"), which the Corporation and the
Issuer Trusts have filed with the Commission under the Securities Act of 1933,
as amended (the "Securities Act"), and to which reference is hereby made,
certain parts of which are omitted in accordance with the rules and regulations
of the Commission.
 
     No separate financial statements of any Issuer Trust have been included or
incorporated by reference herein. The Corporation and the Issuer Trusts do not
consider that such financial statements would be material to Holders of the
Preferred Securities because each Issuer Trust is a newly-formed special-purpose
entity, has no operating history or independent operations and is not engaged in
and does not propose to engage in any activity other than holding as trust
assets the Corresponding Junior Subordinated Debentures and issuing the Trust
Securities and engaging in only those other activities necessary or incidental
thereto. Furthermore, taken together, the Corporation's obligations under each
series of Corresponding Junior Subordinated Debentures, the Junior Subordinated
Indenture, the related Declaration of Trust, the related Expense Agreement and
the related Guarantee, in the aggregate, provide a full, irrevocable and
unconditional guarantee of payments of Distributions and other amounts due on
the Preferred Securities of the Issuer Trust. See "The Issuer Trusts",
"Description of Preferred Securities", "Description of Junior Subordinated
Debentures", "Description of Guarantees" and "Relationship Among the Preferred
Securities, the Corresponding Junior Subordinated Debentures, the Guarantees and

Issuer Trusts will be filing reports under the Exchange Act with the Commission.

                                THE CORPORATION
 
GENERAL
 
     The business of the Corporation and its subsidiaries falls within three
business groups. The Corporation's Engineering and Construction Group (the "E&C
Group") designs, engineers and constructs petroleum, chemical, petrochemical and
alternative-fuels facilities and related infrastructure, including power
generation and distribution facilities, production terminals, pollution control
equipment and water treatment facilities and process plants for the production
of fine chemicals, pharmaceuticals, dyestuffs, fragrances, flavors, food
additives and vitamins. Also, the E&C Group provides a broad range of
environmental remediation services, together with related technical, design and
regulatory services. The Corporation's Energy Equipment Group (the "Energy
Equipment Group") designs, manufactures and erects steam generating and
auxiliary equipment for power stations and industrial markets worldwide. Steam
generating equipment includes a full range of fluidized bed and conventional
boilers firing coal, oil, gas, biomass and other municipal solid waste, waste
wood and low-Btu gases. Auxiliary equipment includes feedwater heaters, steam
condensers, heat-recovery equipment and low-NOx burners. Site services related
to these products encompass plant erection, maintenance engineering, plant
upgrading and life extension, and plant repowering. In addition, the Energy
Equipment Group provides research analysis and experimental work in fluid
dynamics, heat transfer, combustion and fuel technology, materials engineering
and solids mechanics. At the end of June 1997, the Energy Equipment Group sold
Glitsch International, Inc. which provided proprietary solutions and systems for
many separation applications and manufactured highly engineered chemical
separations equipment for the petroleum refining, petrochemical, chemical and
gas processing industries. The Corporation's Power System's Group (the "Power
Systems Group") utilizes Foster Wheeler strengths in design, engineering,
manufacturing and construction to build, own or lease, and operate cogeneration,
independent power production and resource recovery facilities as well as
facilities for the process and petrochemical industries. The Power Systems Group
generates revenues from construction and operating activities pursuant to
long-term off-take and operating and maintenance agreements and from returns on
its equity positions. A special-purpose subsidiary established for each new
project manages that project from the permitting stage through plant
construction and operation. All of the special-purpose subsidiary project debt
is limited-recourse. The Power Systems Group refinances its equity interest in
selected projects from time to time when such refinancing will result in risk
mitigation, a lower effective financing cost or a potential increased return on
investment.
 
     The executive offices of the Corporation, a New York corporation organized
in 1900, are located at Perryville Corporate Park, Clinton, New Jersey 08809,
and the general telephone number is (908) 730-4000.
 
RATIO OF EARNINGS TO FIXED CHARGES
 
     The following table sets forth the ratio of earnings to fixed charges for
the periods indicated:

     The ratio of earnings to fixed charges was calculated based on information
from the Corporation's books and records. In computing the ratio of earnings to
fixed charges, earnings consist of net earnings/loss of the Corporation and its
consolidated subsidiaries, plus income taxes, plus fixed charges and capitalized
interest amortized, less capitalized interest and equity earnings of
non-consolidated associated companies accounted for by the equity method, net of
dividends. Fixed charges consist of interest costs on borrowed funds, including
capitalized interest, commitment fees, and a reasonable approximation of the
imputed interest on non-capitalized lease expense.
 
                               THE ISSUER TRUSTS
 
     Each Issuer Trust is a statutory business trust created under Delaware law
pursuant to (i) a declaration of trust executed by the Corporation, as sponsor
(the "Sponsor") of the Issuer Trust, and the Delaware Trustee (as defined
herein) of such Issuer Trust and (ii) a certificate of trust filed 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 "Declaration of
Trust") substantially in the form filed as an exhibit to the Registration
Statement. Each Declaration of Trust will be qualified as an indenture under the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Corporation will acquire Common Securities in an aggregate liquidation amount
equal to at least 3% of the total capital of such Issuer Trust at the same time
as the Preferred Securities are sold. Each Issuer Trust exists for the exclusive
purposes of (i) issuing and selling its Trust Securities, (ii) using the
proceeds from the sale of such Trust Securities to acquire a series of
Corresponding Junior Subordinated Debentures issued by the Corporation, and
(iii) engaging in only those other activities necessary or incidental thereto
(such as registering the transfer of the Trust Securities). Accordingly, the
Corresponding Junior Subordinated Debentures will be the sole assets of each
Issuer Trust, and payments under the Corresponding Junior Subordinated
Debentures will be the sole source of revenue of such Issuer Trust.
 
     All of the Common Securities of each Issuer Trust will initially be owned
by the Corporation. The Common Securities of an Issuer Trust will rank pari
passu, and payments will be made thereon pro rata, with the Preferred Securities
of such Issuer Trust, except that upon the occurrence of a Trust Enforcement
Event (as defined under "Description of Preferred Securities"), the rights of
the Holder of all 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 Trust. See
"Description of Preferred Securities".
 
     Each Issuer Trust's business and affairs are conducted by its trustees,
each appointed by the Corporation as Holder of all the Common Securities. The
trustees for each Issuer Trust will be Harris Trust and Savings Bank, as the
Property Trustee (the "Property Trustee"), and Wilmington Trust Company, as
Delaware Trustee (the "Delaware Trustee"), and three individual trustees (the
"Administrative Trustees") who are employees or officers of or affiliated with
the Corporation (collectively, the "Issuer Trustees"). Harris Trust and Savings
Bank, as Property Trustee, will act as sole indenture trustee under each
Declaration of Trust for purposes of compliance with the Trust Indenture Act.
Harris Trust and Savings Bank will also act as trustee under the Guarantees (as
defined under "Description of Guarantees") and the Indentures (as defined under
"Description of Debt Securities"). See "Description of Guarantees" and
"Description of Debt Securities". If a Trust Enforcement Event relating thereto
has occurred and is continuing, the Holders of a majority in liquidation amount
of the Related Preferred Securities will be entitled to appoint, remove or
replace the Property Trustee and/or the Delaware Trustee for such Issuer Trust.
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 all the Common Securities. The duties
and obligations of each Issuer Trustee are governed by the applicable
Declaration of Trust.
 
     The Property Trustee will hold title to the Corresponding Junior
Subordinated Debentures for the benefit of the Holders of the related Trust
Securities and, as Holder of such Corresponding Junior Subordinated Debentures,
the Property Trustee will have the power to exercise all rights, powers and
privileges of a Holder of Corresponding Junior Subordinated Debentures under the
Junior Subordinated Indenture. In addition, the Property Trustee will maintain
exclusive control of a non-interest bearing bank account (the "Property
 
                                        4
<PAGE>   44
 
Account") to hold all payments made in respect of the Corresponding Junior
Subordinated Debentures for the benefit of the Holders of the related Trust
Securities. The Corporation, as Holder of all the Common Securities, will have
the right to appoint, remove or replace any of the Issuer Trustees and to
increase or decrease the number of Issuer Trustees; provided that after the
issuance of the Trust Securities, the number of Issuer Trustees will at all
times be at least three; and provided further, that after the issuance of the
Trust Securities, at least one Issuer Trustee will be a Delaware Trustee, one
Issuer Trustee will be a Property Trustee and one Issuer Trustee will be an
Administrative Trustee. The Corporation, as issuer of the Corresponding Junior
Subordinated Debentures to be acquired and held by the Issuer Trusts, will pay
all fees and expenses related to the organization and operations of the Issuer
Trusts (including any taxes, duties, assessments or governmental charges of
whatever nature, other than United States withholding taxes, imposed by the
United States or any other domestic taxing authority upon the Issuer Trusts) and
the offering of the Trust Securities and be responsible for all debts and
obligations of the Issuer Trusts (other than with respect to the Trust
Securities).
 
     With respect to each Issuer Trust, for so long as the Preferred Securities
of such Issuer Trust remain outstanding, the Corporation will covenant, among
other things, to maintain 100% ownership of the Common Securities of such Issuer
Trust, to cause such Issuer Trust to remain a statutory business trust and to
use its commercially reasonable efforts to ensure that such Issuer Trust will
not be an "investment company" for purposes of the Investment Company Act of
1940 (the "Investment Company Act").
 
     The rights of the Holders of the Preferred Securities of an Issuer Trust,
including economic rights, rights to information and voting rights, are set
forth in the Declaration of Trust of each Issuer Trust and the Trust Indenture
Act. See "Description of Preferred Securities". The Declarations of Trust and
the Guarantees also incorporate by reference the terms of the Trust Indenture
Act.
 
     The principal executive office of each Issuer Trust is c/o Foster Wheeler
Corporation, Perryville Corporate Park, Clinton, New Jersey, 08809 and its
telephone number is (908) 730-4000.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The Senior Debt Securities and the Senior Subordinated Debt Securities may
be issued by the Corporation from time to time in one or more series under an
Indenture, dated as of November 17, 1995 (the "1995 Indenture"), between the
Corporation and Harris Trust and Savings Bank, as Trustee. The Junior
Subordinated Debentures may be issued by the Corporation from time to time in
one or more series under an Indenture, the form of which has been filed as an
exhibit to the Registration Statement (the "Junior Subordinated Indenture" and,
together with the 1995 Indenture, the "Indentures"), between the Corporation and
Harris Trust and Savings Bank, as Trustee (in its capacity as Trustee under
either the 1995 Indenture or the Junior Subordinated Indenture, as applicable,
the "Indenture Trustee"). The following summaries of certain provisions of the
Debt Securities and the Indentures, as modified or superseded by any applicable
Prospectus Supplement, are brief summaries of certain provisions thereof, do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all of the provisions of the relevant Indenture. Capitalized
terms are used as defined in the 1995 Indenture and the Junior Subordinated
Indenture, as applicable, unless otherwise defined herein. Whenever any term
defined therein is referred to, such definition is incorporated herein by
reference.
 
GENERAL
 
     Neither Indenture limits the amount of Debt Securities that may be issued
thereunder, and each provides that additional Debt Securities may be issued in
one or more series thereunder up to the aggregate principal amount that may be
authorized from time to time by the Corporation's Board of Directors (the "Board
of Directors"). The Senior Debt Securities will be unsecured senior obligations
of the Corporation and will rank equally and ratably with all other unsecured
unsubordinated indebtedness of the Corporation. As will be described more fully
in the applicable Prospectus Supplement, the Senior Subordinated Debt Securities
will be subordinated in right of payment to the prior payment in full of all
Senior Debt (as defined below under "-- Certain Covenants of the Corporation
under the 1995 Indenture -- Definitions") of the Corporation. See "-- Senior
Subordinated Debt Securities". The Junior Subordinated Debentures will be
subordinated and junior in right of payment to the prior payment in full of all
Senior Indebtedness (as defined under "-- Junior
                                        5
<PAGE>   45
 
Subordinated Debentures -- Subordination") of the Corporation. See "-- Junior
Subordinated Debentures -- Subordination".
 
     In the event that Junior Subordinated Debentures are issued to an Issuer
Trust or an Issuer Trustee thereof in connection with the issuance of Trust
Securities by such Issuer Trust, such Junior Subordinated Debentures may
subsequently be distributed pro rata to the Holders of such Trust Securities as
will be described in the Prospectus Supplement relating to such Trust
Securities. Only one series of Junior Subordinated Debentures will be issued to
an Issuer Trust or an Issuer Trustee thereof in connection with the issuance of
Trust Securities by such Trust.
 
     Reference is made to the Prospectus Supplement relating to the particular
Debt Securities offered thereby for the following terms, where applicable, of
the Debt Securities: (i) the specific designation of the Debt Securities; (ii)
the denominations in which such Debt Securities are authorized to be issued;
(iii) the aggregate principal amount of such Debt Securities; (iv) the date or
dates on which the principal and premium, if any, of such Debt Securities will
mature or the method of determining such date or dates; (v) the price or prices
(expressed as a percentage of the aggregate principal amount thereof) at which
the Debt Securities will be issued; (vi) the rate or rates (which may be fixed

which, the price or prices at which, the currency or currencies (including
currency units) in which, and the terms and conditions upon which, such Debt
Securities may be redeemed, in whole or in part, at the option of the
Corporation, pursuant to any sinking fund or otherwise; (xi) the obligation, if
any, of the Corporation to redeem or purchase such Debt Securities pursuant to
any sinking fund or analogous provisions, upon the happening of a specified
event or at the option of a Holder thereof and the period or periods within
which, the price or prices at which and the terms and conditions upon which,
such Debt Securities shall be redeemed or purchased, in whole or in part,
pursuant to such obligations; (xii) the terms and conditions, if any, pursuant
to which the Debt Securities are convertible or exchangeable into Common Stock
or Preferred Stock or other debt securities, including the conversion or
exchange price, the conversion or exchange period and other conversion or

Securities may be purchased or in which such Debt Securities may be denominated
and/or the currency or currency units in which principal of, premium, if any,

Corporation or the Holders of any such Debt Securities may elect to receive
payments in respect of such Debt Securities in a currency or currency units
other than that in which such Debt Securities are stated to be payable; (xiv)
any index or formula used to determine the amount of payments of principal of
and premium, if any, and interest; (xv) if other than the principal amount
thereof, the portion of the principal amount of such Debt Securities that will

method by which such portion shall be determined; (xvi) the person to whom any
interest on any such Debt Security shall be payable if other than the person in

Indenture with respect to such Debt Securities; (xviii) the application, if any,

Debt Securities; (xix) whether such Debt Securities are to be issued in whole or
in part in the form of one or more temporary or permanent global securities and,
if so, the identity of the depositary for such global security or securities;
(xx) subordination terms, if any, applicable to such Debt Securities; (xxi) the
right, if any, to extend the interest payment periods and the duration of such

See "Description of Warrants -- Debt Warrants." Unless otherwise specified in
the applicable Prospectus Supplement, the Debt Securities will not be listed on
any securities exchange.
                                        6
<PAGE>   46
 
     Some of the Debt Securities may be issued at a discount (bearing no
interest or interest at below market rates) ("Discount Securities") to their
stated principal amount. United States Federal income tax consequences and other
special considerations applicable to any such Discount Securities or any Debt
Securities which are denominated in a currency or composite currency other than
United States dollars will be described in the applicable Prospectus Supplement.
 
     Since the Corporation is a holding company, the rights of the Corporation,
and hence the right of creditors of the Corporation (including the Holders of
Debt Securities), to participate in any distribution of the assets of any
subsidiary upon its liquidation or reorganization otherwise is necessarily
subject to the prior claims of creditors of any such subsidiary except to the
extent that claims of the Corporation itself as a creditor of the subsidiary may
be recognized.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
covenants contained in the Indentures and the Debt Securities would not provide
for redemption at the option of a Holder nor necessarily afford Holders thereof
protection in the event of a highly leveraged or other transaction that may
adversely affect such Holders, except to the extent described under
"-- Consolidation, Merger and Sale of Assets." Such covenants may not be waived
or modified by the Corporation or its Board of Directors, although Holders of
Debt Securities could waive or modify such covenants as more fully described
below under "-- Modification and Waiver."
 
CONVERSION OR EXCHANGE OF DEBT SECURITIES
 
     If so indicated in the applicable Prospectus Supplement with respect to a
particular series of Debt Securities, such series will be convertible or
exchangeable into Common Stock, Preferred Stock or other securities on the terms
and conditions set forth therein. Such terms will include provisions as to
whether conversion is mandatory, at the option of the Holder or at the option of
the Corporation, and may include provisions pursuant to which the number of
shares of Common Stock, Preferred Stock or other securities of the Corporation
to be received by the Holders of such Debt Securities would be calculated
according to the market price of Common Stock, Preferred Stock or other
securities of the Corporation as of a time stated in the Prospectus Supplement.
The applicable Prospectus Supplement will indicate restrictions on ownership
that may apply in the event of a conversion or exchange.
 
FORM, EXCHANGE, REGISTRATION, TRANSFER AND PAYMENT
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Debt Securities will be issued in fully registered form without coupons in
denominations set forth in the Prospectus Supplement. No service charge will be
made for any transfer or exchange of such Debt Securities, but the Corporation
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Where Debt Securities of any series are
issued in bearer form, the special restrictions and considerations, including
special offering restrictions and special United States Federal income tax
considerations, applicable to any such Debt Securities and to payment on and
transfer and exchange of such Debt Securities will be described in the
Prospectus Supplement. Debt Securities in bearer form will be transferable by
delivery.
 
     Unless otherwise provided in the applicable Prospectus Supplement,
principal and premium, if any, or interest, if any, will be payable and the Debt
Securities may be surrendered for payment or transferred at the offices of the
Indenture Trustee as paying and authenticating agent, provided that payment of
interest on registered securities may be made at the option of the Corporation
(i) by check mailed to the address of the person entitled thereto as it appears
in the applicable Security Register or (ii) by wire transfer to an account
maintained by the person entitled thereto as specified in the applicable
Security Register. Payment of Debt Securities in bearer form will be made at
such paying agencies outside of the United States as the Corporation may
appoint.
 
BOOK-ENTRY DEBT SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on behalf
of, a depositary (the "Global Depositary"), or its nominee,
                                        7
<PAGE>   47
 
identified in the Prospectus Supplement relating to such series. In such a case,
one or more Global Securities will be issued in a denomination or aggregate
denomination equal to the portion of the aggregate principal amount of
outstanding Debt Securities of the series to be represented by such Global
Security or Securities. Unless and until it is exchanged in whole or in part for
Debt Securities in definitive registered form, a Global Security may not be
registered for transfer or exchange except as a whole by the Global Depositary
for such Global Security to a nominee for such Global Depositary and except in
the circumstances described in the applicable Prospectus Supplement.
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Debt Securities to be represented by a Global Security
and a description of the Global Depositary will be provided in the applicable
Prospectus Supplement.

lien on ("Lien"), any Principal Property of the Corporation or any Subsidiary,
or any shares of stock or Debt of any Subsidiary without effectively providing
that the Debt Securities of all series issued pursuant to the 1995 Indenture
(together with, if the Corporation shall so determine, any other Debt of the
Corporation or such Subsidiary then existing or thereafter created which is not
subordinate to the Debt Securities) shall be secured equally and ratably with
(or, at the option of the Corporation, prior to) such Secured Debt, so long as
such Secured Debt shall be so secured, unless after giving effect thereto, the
aggregate principal amount of all such Secured Debt then outstanding which would
otherwise be prohibited, plus all Attributable Debt of the Corporation and its
Subsidiaries in respect of sale and leaseback transactions (as defined in
"-- Restrictions on Sales and Leasebacks") occurring after the date of the 1995
Indenture and existing at such time which would otherwise be prohibited by the
covenant described in "-- Restrictions on Sales and Leasebacks", would not
exceed 5% of Consolidated Net Tangible Assets. This restriction does not apply
to, and there shall be excluded in computing secured Debt for the purpose of

     financing all or any part of the purchase price or construction cost or

     that any such Liens shall only extend to the above-described property or
     property on which the above-described property is situated;
 
          (2) Liens on property of, or on any shares of stock or Debt of, any
     corporation or other Person existing at the time such corporation becomes a
     Restricted Subsidiary;
 
          (3) Liens on property of, or on any shares of capital stock or Debt of
     any Corporation or other Person existing at the time such Corporation or
     other Person is merged into or consolidated with the Corporation or a

     partial, progress, advance or other payments pursuant to any contract or

     other like Liens, or deposits to obtain the release of such Liens;
 
          (5) Liens on any property or assets of any Restricted Subsidiary to
     secure Debt owing by it to the Corporation or any other Restricted
     Subsidiary;
 
          (6) Liens arising out of judgments or awards against the Corporation
     or any subsidiary that the Corporation or such subsidiary is contesting in
     good faith;
 
          (7) Liens made in favor of any customer arising in the ordinary course
     of business of the Corporation or any subsidiary in respect of payments
     made by or on behalf of such customer for goods produced or services
     rendered to such customer,
 
          (8) Liens existing at the date of the 1995 Indenture;
 
          (9) Liens created to secure Project Debt, but only to the extent that
     any such Lien does not extend beyond the assets, contractual rights and
     revenues of such project and the capital stock of the corporation owning
     such project, and any extension, renewal, refunding, replacement or
     refinancing (or successive extensions, renewals, replacements, refundings
     or refinancings) as a whole or in part of any Liens referred to in this
     clause (9); and
 
          (10) Any extension, renewal, refunding or replacement (or successive
     extensions, renewals, refundings or replacements), as a whole or in part,
     of any Lien referred to in the foregoing clauses (1) through (3) and (8),
     inclusive; provided, however, that (i) such extension, renewal, refunding
     or replacement Lien shall be limited to all or a part of the same property,
     shares of stock or Debt that secured the Lien extended, renewed, refunded
     or replaced (plus improvements on such property) and (ii) the Debt secured
     by such Lien at such time is not increased.
 
  Restrictions on Sales and Leasebacks
 
     In the 1995 Indenture, the Corporation has covenanted that it will not, and
will not permit any Subsidiary to, enter into any arrangement with any bank,
insurance company or other lender or investor (not including the Corporation or
any Subsidiary) or to which any such lender or investor is a party, providing
for the leasing by the Corporation or any such Subsidiary of any Principal
Property which has been owned and operated by the Corporation or such Subsidiary
for more than 180 days and which has been sold or transferred by the Corporation
or such Subsidiary to such lender or investor or to any Person to whom funds
have been advanced by such lender or investor (each, a "sale and leaseback
transaction") unless, after giving effect thereto, the aggregate amount of all
Attributable Debt of the Corporation and its Subsidiaries in respect of such
sale and leaseback transactions occurring after the date of the 1995 Indenture
and existing at such time which would otherwise be prohibited under the covenant
described in "-- Restrictions on Sales and Leasebacks" plus all secured Debt
then outstanding of the Corporation and its Subsidiaries incurred after the date
of the 1995 Indenture which would otherwise be prohibited by the covenant
described in "-- Limitation on Liens", would
                                       10
<PAGE>   50
 
not exceed 5% of Consolidated Net Tangible Assets. This restriction does not
apply to, and there shall be excluded from Attributable Debt in any computation
under such restriction, Attributable Debt with respect to any sale and leaseback
transaction under any of the following circumstances:
 
          (1) the lease in such sale and leaseback transaction is for a period,
     including renewals, of not in excess of three years; or
 
          (2) the property which is the subject of the sale and leaseback
     transaction is property capable of being subject to a Lien described in
     clauses (1), (2), (3), (8) or (9) in the covenant described in
     "-- Limitation on Liens"; or
 
          (3) the Corporation or a Subsidiary, within 180 days after the sale or
     transfer shall have been made by the Corporation or by any such Subsidiary,
     applies an amount equal to the lesser of (i) Attributable Debt or (ii) the
     net proceeds of any such sale or transfer to (a) the acquisition of other
     Principal Property of equal fair market value (as determined by the Board
     of Directors) or (b) the retirement of indebtedness for pari passu borrowed
     money (including Debt Securities of any series).
 
  Limitation on Debt Incurred by Restricted Subsidiaries
 
     In the 1995 Indenture, the Corporation has covenanted that it will not
permit any Restricted Subsidiary to directly or indirectly, incur, assume or
suffer to exist any Debt, unless, after giving effect thereto, the aggregate
amount of then outstanding Debt incurred by all Restricted Subsidiaries,
excluding all Secured Debt and Attributable Debt in respect of sale and
leaseback transactions, shall not exceed 10% of Consolidated Net Tangible
Assets. The immediately preceding sentence shall not apply to the incurrence or
issuance of (a) Existing Debt, (b) Working Debt, (c) Debt of a Restricted
Subsidiary which represents the assumption by such Restricted Subsidiary of Debt
of another Restricted Subsidiary as a result of the merger or acquisition of
such Restricted Subsidiary, (d) Debt of any Corporation existing at the time
such corporation becomes a Restricted Subsidiary, (e) Permitted Secured Debt and
(f) Project Debt which does not constitute Secured Debt.
 
  No Similar Restrictive Covenants in the Junior Subordinated Indenture
 
     The Junior Subordinated Indenture contains no covenants analogous to those

Indenture -- Limitation on Liens" and "-- Restrictions on Sales and Leasebacks".

     included in the 1995 Indenture and designated as being solely for the
     benefit of such series of Debt Securities other than such
 
                                       11
<PAGE>   51
 
     series), and continuance of such default or breach for a period of 90 days

     Corporation by the Indenture Trustee or to the Corporation and the
     Indenture Trustee by the Holders of at least 25% in principal amount of the
     Debt Securities of such series then outstanding, a written notice
     specifying such default or breach and requiring it to be remedied and
     stating that such notice is a "Notice of Default" under the 1995 Indenture;
     or
 
          (5) default resulting in acceleration of or failure to pay at maturity
     (i) other Debt of the Corporation or Debt that the Corporation has
     guaranteed where the aggregate principal amount so accelerated exceeds $15
     million or (ii) Debt of any Subsidiary which the Corporation has directly
     assumed or on which the Corporation has otherwise become directly liable as
     a result of the exercise of remedies upon the occurrence of a default by
     such Subsidiary in the performance of its obligations under any agreement
     guaranteed by the Corporation in a principal amount of $15 million or more;
     without such involuntary acceleration having been rescinded or annulled
     within a period of 30 days after there shall have been given, by registered
     or certified mail, to the Corporation by the Indenture Trustee or to the
     Corporation and the Indenture Trustee by the Holders of at least 25% in
     aggregate principal amount of the Debt Securities of such series then
     outstanding a written notice specifying such default and requiring the
     Corporation to cause such acceleration to be rescinded or annulled and
     stating that such notice is a "Notice of Default" under the 1995 Indenture;
     provided, however, that, if such default shall be remedied or cured by the
     Corporation or waived by the Holders of such indebtedness before any
     judgment or decree for the payment of money due shall have been obtained or
     entered, then the Event of Default under the Indenture by reason thereof
     shall be deemed likewise to have been thereupon remedied, cured or waived
     without any action on the part of the Indenture Trustee or any of the
     Holders; or
 
          (6) a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of the Corporation in an involuntary case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law then or thereafter in effect, or
     appointing a receiver, liquidator, assignee, custodian, trustee or
     sequestrator (or similar official) of the Corporation or for all or
     substantially all of its property or ordering the winding up or liquidation
     of its affairs, and such decree or order shall remain unstayed and in
     effect for a period of 60 consecutive days; or
 
          (7) the Corporation shall commence a voluntary case or proceeding
     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law then or thereafter in effect, or
     consent to the entry of an order for relief in an involuntary case under
     any such law, or consent to the appointment or taking possession by a
     receiver, liquidator, assignee, custodian, trustee or sequestrator (or
     similar official) of the Corporation or for all or substantially all of its
     property, or make any general assignment for the benefit of creditors; or
 
          (8) any other Event of Default provided with respect to Debt
     Securities of such series.
 
  Events of Default under the Junior Subordinated Indenture
 
     The Junior Subordinated Indenture provides that any one or more of the
following events that has occurred and is continuing constitutes an "Event of
Default":
 
          (i) failure for 30 days to pay any interest on 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 of (or premium, if any) on the
     Junior Subordinated Debentures when due, whether at maturity or upon
     redemption, by declaration, by acceleration or otherwise; or
 
          (iii) failure to observe or perform in any material respect certain
     other covenants or agreements contained in the Junior Subordinated
     Indenture that shall not have been remedied for 90 days after written
     notice to the Corporation from the Indenture Trustee or to the Indenture
     Trustee and the Corporation by the holders of at least 25% in aggregate
     outstanding principal amount of the outstanding Junior Subordinated
     Debentures of that series; or
 
          (iv) certain events of bankruptcy, insolvency or reorganization of the
     Corporation; or
 
                                       12
<PAGE>   52
 
          (v) any other Event of Default with respect to a particular series of
     Junior Subordinated Debentures as described in the related Prospectus
     Supplement.
 
  Provisions Applicable to Events of Default under either Indenture
 
     If an Event of Default (as used herein, "Event of Default" with respect to
a particular series of Debt Securities shall refer to an Event of Default under
the Indenture under which such series was issued) with respect to Debt
Securities of any series at the time outstanding occurs and is continuing, then,
and in each and every such case, unless the principal of all of the Debt
Securities of such series shall have already become due and payable, either the
Indenture Trustee or the Holders of not less than 25% in aggregate principal
amount of the Debt Securities of such series then outstanding, by notice in
writing to the Corporation (and to the Indenture Trustee if given by Holders),
may declare the entire principal amount (or, if the Debt Securities of such
series are Discount Securities (as defined in the applicable Indenture), such
portion of the principal as may be specified in the terms of such series) of all
of the Debt Securities of such series and any premium and interest accrued
thereon to be due and payable immediately, and upon any such declaration such
principal amount (or specified amount) and any premium and interest accrued
thereon shall become immediately due and payable. With regard to Corresponding
Junior Subordinated Debentures held by an Issuer Trust, if the Indenture Trustee
or such percentage of Holders of Corresponding Junior Subordinated Debentures
fails to make such declaration, the Holders of at least 25% in aggregate
liquidation amount of the outstanding Related Preferred Securities will have
such right.
 
     However, 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 such acceleration has been obtained, the Holders of a majority in
principal amount of outstanding Debt Securities of that series may, under
certain circumstances, rescind and annul such acceleration. See also
"-- Modification and Waiver." In the case of Corresponding Junior Subordinated
Debentures, if the Holders of such Corresponding Junior Subordinated Debentures
fail to rescind and annul such declaration, the Holders of a majority in
aggregate liquidation amount of the Related Preferred Securities will have such
right.
 
     Reference is made to the Prospectus Supplement relating to each series of
Debt Securities which are Discount Securities for the particular provisions
relating to acceleration of the Maturity of a portion of the principal amount of
such Discount Securities upon the occurrence of an Event of Default and the
continuation thereof.
 
     Each Indenture provides that, subject to the duty of the Indenture Trustee
during default to act with the required standard of care, the Indenture Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders, unless such Holders
shall have offered to the Indenture Trustee reasonable indemnity. Subject to
such provisions for indemnification of the Indenture Trustee, the Holders of a
majority in 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 Indenture Trustee, or exercising any
trust or power conferred on the Indenture Trustee, with respect to the Debt
Securities of that series.
 
     The occurrence of an Event of Default in respect of a series of
Corresponding Junior Subordinated Debentures will also constitute a Trust
Enforcement Event in respect of the Related Preferred Securities and related
Common Securities. See "Description of Preferred Securities."
 
     If an Event of Default occurs and is continuing with respect 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 Indenture with
respect thereto, to be forthwith due and payable and to enforce its other rights
as a creditor with respect to such Corresponding Junior Subordinated Debentures.
 
     The Corporation is required to furnish to the Indenture Trustee annual
statements as to the performance by the Corporation of certain of its
obligations under each Indenture and as to any default in such performance.

MODIFICATION AND WAIVER
 
  1995 Indenture
 
     Modifications and amendments of the 1995 Indenture may be made by the
Corporation and the Indenture Trustee with the consent of the Holders of a
majority in principal amount of the outstanding Debt Securities of each series
affected thereby (each such series voting as a single class); provided, however,
that no such modification or amendment may, without the consent of the Holder of
each outstanding Debt Security affected thereby, (a) change the Stated Maturity
of the principal, or any installment of principal of or interest on, any Debt
Security, (b) reduce the principal amount thereof, or reduce any premium thereof
or change the time of payment of any premium thereon, (c) reduce the rate or
change the time of payment of interest thereon, if any, (d) reduce any amount
payable on redemption of any such Debt Security (if any), (e) reduce the overdue
rate thereof, (f) change the place or currency of payment of principal of, or
any premium or interest thereon, (g) reduce, if applicable, the amount of
principal of any Discount Security payable upon acceleration of the Maturity
thereof or the amount thereof provable in bankruptcy, (h) impair, if applicable,
any right of repayment at the option of the Holder, (i) impair the right to
institute suit for the enforcement of any payment on or with respect to any Debt
Security, or (j) reduce the percentage in principal amount of outstanding Debt
Securities of any series, the consent of the Holders of which is required for
modification or amendment of the 1995 Indenture or for waiver of compliance with
certain provisions of the 1995 Indenture or for waiver of certain defaults, or
(k) alter or impair the right of any Holder to convert or exchange Debt
Securities of any series, if applicable, at the rate and upon the terms
established pursuant to the 1995 Indenture.
 
  Junior Subordinated Indenture
 
     The Junior Subordinated Indenture contains provisions permitting the
Corporation and the Indenture Trustee, with the consent of the Holders of not
less than a majority in aggregate principal amount of the Junior Subordinated
Debentures of all series affected by such modification or amendment at the time
outstanding, to amend the Junior Subordinated Indenture or modify the rights of
the Holders of the Junior Subordinated Debentures; provided, that no such
amendment or modification shall (i) change the Stated Maturity of any Junior
Subordinated Debenture or reduce the principal amount thereof or reduce the rate
or extend the time for payment of interest thereon, or make the principal
thereof, or interest or premium, if any, thereon, payable in any coin or
currency other than that provided in such Junior Subordinated Debentures, or
impair or affect the right of any Holder of Junior Subordinated Debentures to
institute suit for the payment thereon or reduce any amount payable on
prepayment thereof, without the consent of each Holder of Junior Subordinated
Debentures so affected, or (ii) reduce the aforesaid percentage of principal
amount of Junior Subordinated Debentures for which the consent of the Holders is
required for any such modification, without the consent of each Holder of Junior
Subordinated Debentures so affected. Furthermore, in the case of Corresponding
Junior Subordinated Debentures, so long as any of the Related Preferred
Securities remain outstanding, (a) no such modification may be made that
adversely affects the Holders of such Preferred Securities in any material
respect, and no termination of the Junior Subordinated Indenture may occur, and
no waiver of any event of default or compliance with any covenant under the
Junior Subordinated Indenture in respect of such series of Junior Subordinated
Debentures may be effective, without the prior consent of the Holders of at
least a majority in aggregate liquidation amount of all the outstanding Related
Preferred Securities unless and until the principal of (and premium, if any, on)
the Corresponding Junior Subordinated Debentures and all accrued and unpaid
interest thereon have been paid in full and certain other conditions are
satisfied and (b) where a consent under the Junior Subordinated Indenture would
require the consent of each Holder of Corresponding Junior Subordinated
Debentures, no such consent may be given by the Property Trustee without the
prior consent of each Holder of Related Preferred Securities.
 
  The Indentures Generally
 
     The Holders of a majority in aggregate principal amount of the outstanding
Debt Securities of any series may on behalf of the Holders of all Debt
Securities of that series waive, insofar as that series is concerned, compliance
by the Corporation with certain restrictive provisions of the applicable
Indenture. In the case of
 
                                       14
<PAGE>   54
 
Corresponding Junior Subordinated Debentures, if the Holders of such
Corresponding Junior Subordinated Debentures fail to waive such compliance, the
Holders of a majority in aggregate liquidation amount of the Related Preferred
Securities will have such right. The Holders of a majority in principal amount
of the outstanding Debt Securities of any series may, on behalf of the Holders
of all Debt Securities of that series, direct the Indenture Trustee as to the
time, method and place of pursuing any remedy available to it or exercising any
trust or power conferred on it and may waive any past default under the
Indenture with respect to Debt Securities of that series, except a default not
theretofore cured in the payment of the principal of (or premium, if any) or
interest on any Debt Securities of that series or in respect of any provision
which under the applicable Indenture cannot be modified or amended without the
consent of the Holder of each outstanding Security of that series affected.
 
     Each Indenture contains provisions, where applicable, permitting the
Corporation and the Indenture Trustee to enter into one or more supplemental
indentures without the consent of the Holders of any of the Debt Securities in
order (i) to evidence the succession of another corporation to the Corporation
and the assumption of the covenants of the Corporation by a successor to the
Corporation; (ii) to add to the covenants of the Corporation or surrender any
right or power of the Corporation; (iii) to add additional Events of Default
with respect to any series of Debt Securities; (iv) to add to, change or
eliminate any provision affecting Debt Securities not yet issued; (v) to secure
the Debt Securities (in the case of Debt Securities issued under the 1995
Indenture only); (vi) to establish the form or terms of Debt Securities; (vii)
to evidence and provide for a successor Indenture Trustee; and (viii) to cure
any ambiguity or correct any mistake or to correct any defect or supplement any
inconsistent provisions or to make any other provisions with respect to matters
or questions arising under the Indenture, provided that such action does not
adversely affect the interests of any Holder of Debt Securities of any series.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Corporation may not consolidate or merge with or into, or convey,
transfer or lease all or substantially all its properties and assets to, any
Person, and any other Person may not consolidate or merge with or into, the
Corporation, unless (i) the Person (if other than the Corporation) formed by
such consolidation or into which the Corporation is merged or which acquires or
leases all or substantially all the assets of the Corporation is organized and
existing under the laws of the United States, any state thereof or the District
of Columbia and expressly assumes all of the Corporation's obligations under the
Debt Securities and under the applicable Indenture, (ii) immediately after
giving effect to such 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
happened and be continuing (provided that a transaction will only be deemed to
be in violation of this condition (ii) as to any series of Debt Securities as to
which such Event of Default or such event shall have occurred and be
continuing), and (iii) with respect to the 1995 Indenture only, the Trustee
receives an Opinion of Counsel and an Officers' Certificate that such
consolidation, merger, conversion, transfer or lease and such assumption
complies with the terms of the 1995 Indenture and all conditions precedent set
forth in the 1995 indenture relating to such transaction have been complied
with.
 
SATISFACTION, DISCHARGE, AND DEFEASANCE PRIOR TO MATURITY OR REDEMPTION
 
  Covenant Defeasance of any Series Issued under the 1995 Indenture
 
     If the Corporation shall deposit with the Indenture Trustee, in trust, at
or before maturity or redemption of the Debt Securities of any series issued
under the 1995 Indenture, money and/or Government Obligations in such amounts
and maturing at such times such that the proceeds of such obligations to be
received upon the respective maturities and interest payment dates of such
obligations will provide funds sufficient, without reinvestment, in the opinion
of a nationally recognized firm of independent public accountants, to pay when
due the principal of (and premium, if any) and each installment of principal of
(and premium, if any) and interest on such series of Debt Securities at the
Stated Maturity of such principal or installment of principal or interest, as
the case may be, then the Corporation may omit to comply with certain of the
terms of the 1995 Indenture with respect to that series of Debt Securities,
including any or all of the restrictive covenants described above or in any
Prospectus Supplement, and the Events of Default described in clauses (4) and
(5)
 
                                       15
<PAGE>   55
 
under "Events of Default -- Events of Default under the 1995 Indenture" shall
not apply. Defeasance of Debt Securities of any such series is subject to the
satisfaction of certain conditions, including among others: (1) the absence of
an Event of Default or event which, with notice or lapse of time, would become
an Event of Default at the date of the deposit, (2) the delivery to the
Indenture Trustee by the Corporation of an Opinion of Counsel to the effect that
Holders of the Debt Securities of such series will not recognize income, gain or
loss for United States Federal income tax purposes as a result of such deposit
and covenant defeasance and will be subject to United States Federal income tax
in the same amounts and in the same manner and at the same times as would have
been the case if such deposit and covenant defeasance had not occurred, (3) such
covenant defeasance will not cause any Debt Securities of such series then
listed on any nationally recognized securities exchange to be delisted, (4) that
such covenant defeasance will not result in a breach of, or constitute a default
under, any instrument by which the Corporation is bound and (5) such covenant
defeasance shall not cause the Indenture Trustee for the Securities of such
series to have a "conflicting interest" (as defined in Section 310(b) of the
Trust Indenture Act) with respect to any securities of the Corporation. If
indicated in the Prospectus Supplement relating to a series of Debt Securities,
in addition to the obligations of the United States of America or obligations
guaranteed by the United States of America, Government Obligations may include
obligations of the government, and obligations guaranteed by such government,
issuing the currency or currency unit in which Debt Securities of such series
are payable.
 
  Defeasance of any Series Issued under the 1995 Indenture
 
     Upon the deposit of money or securities as contemplated in the preceding
paragraph and the satisfaction of certain other conditions, the Corporation may
also omit to comply with its obligation duly and punctually to pay the principal
of (and premium, if any) and interest on a particular series of Debt Securities
issued under the 1995 Indenture, and any Events of Default with respect thereto
shall not apply, and thereafter, the Holders of Debt Securities of such series
shall be entitled only to payment out of the money or securities deposited with
the Indenture Trustee. Such conditions include among others: (1) the absence of
an Event of Default or event which, with notice or lapse of time, would become
an Event of Default at the date of the deposit, (2) the delivery to the
Indenture Trustee by the Corporation of an Opinion of Counsel, which refers to
or is based on a ruling of the Internal Revenue Service or a change in the
applicable United States Federal income tax law occurring after the date of the
Indenture, to the effect that Holders of the Debt Securities of such series will
not recognize income, gain or loss for United States Federal income tax purposes
as a result of such deposit and the satisfaction, discharge and defeasance, and
will be subject to United States Federal income tax in the same amounts and in
the same manner and at the same times as would have been the case if such
deposit and defeasance had not occurred, (3) such defeasance will not cause any
Debt Securities of such series then listed on any nationally recognized
securities exchange to be delisted, (4) that such defeasance will not result in
a breach of, or constitute a default under, any instrument by which the
Corporation is bound and (5) such defeasance shall not cause the Indenture
Trustee for the Securities of such series to have a conflicting interest for the
purpose of the Trust Indenture Act with respect to any securities of the
Corporation.
 
SATISFACTION AND DISCHARGE OF THE JUNIOR SUBORDINATED INDENTURE
 
     The Junior Subordinated Indenture provides that when, among other things,
all Junior Subordinated Debentures of a series not previously delivered to the
Indenture 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
Corporation deposits or causes to be deposited with the Indenture Trustee trust
funds, in trust, for the purpose of, and in an amount sufficient for, payment
and discharge of the entire indebtedness on the Junior Subordinated Debentures
of such series not previously delivered to the Indenture 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 Junior
Subordinated Indenture will cease to be of further effect with respect to the
series (except as to the Corporation's obligations to pay all other sums due
with respect to that series pursuant to the Junior Subordinated Indenture and to
provide the officer's certificates and opinions of counsel described therein),
and the Corporation will be deemed to have satisfied and discharged the Junior
Subordinated Indenture with respect to that series.
 
                                       16

SENIOR DEBT SECURITIES
 
     The Debt Securities that will be designated and will constitute part of the
Senior Debt and Senior Indebtedness of the Corporation, will rank pari passu
with all other unsecured and unsubordinated Debt of the Corporation.
 
SENIOR SUBORDINATED DEBT SECURITIES
 
     The Senior Subordinated Debt Securities, may be subordinated and junior in
right of payment, to the extent set forth in the applicable Prospectus
Supplement, to all Senior Debt.
 
JUNIOR SUBORDINATED DEBENTURES
 
  Corresponding Junior Subordinated Debentures
 
     The Corresponding Junior Subordinated Debentures may be issued in one or
more series of Junior Subordinated Debentures under the Junior Subordinated
Indenture in connection with the issuance of a series of Related Preferred
Securities by an Issuer Trust. In that event, concurrently with the issuance of
such Issuer Trust's Preferred Securities, such Issuer Trust will invest the
proceeds thereof and the consideration paid by the Corporation for the Common
Securities of such Issuer Trust in such series of Corresponding Junior
Subordinated Debentures, which will be issued by the Corporation to such Issuer
Trust. Each series of Corresponding Junior Subordinated Debentures will be in a
principal amount equal to the aggregate stated liquidation amount of the Related
Preferred Securities and the Common Securities of such Issuer Trust. Holders of
the Related Preferred Securities for a series of Corresponding Junior
Subordinated Debentures will have the rights in connection with modifications to
the Indenture or upon occurrence of Events of Default, as described under
"-- Modification and Waiver" and "-- Events of Default -- Events of Default
under the Junior Subordinated Indenture", unless provided otherwise in the
applicable Prospectus Supplement.
 
  Deferral of Interest Payments
 
     If provided in the applicable Prospectus Supplement, the Corporation will
have the right under the Junior Subordinated Indenture and the Corresponding
Junior Subordinated Debentures to defer the payment of interest at any time or
from time to time on any series of Corresponding Junior Subordinated Debentures
for up to such number of consecutive interest payment periods as may be
specified in such 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 in effect
at the time of the Corporation's election to defer interest in this manner. As a
consequence of any such election, Distributions on the Related Preferred
Securities would be deferred (but would continue to accumulate additional
Distributions thereon at the rate per annum set forth in the Prospectus
Supplement for such Preferred Securities) by the Issuer Trust of such Preferred
Securities during any such Extension Period. During any such Extension Period,
the Corporation may not (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Corporation's capital stock, (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Corporation that rank pari passu with or junior in interest to the Corresponding
Junior Subordinated Debentures, or (iii) make any guarantee payments with
respect to any guarantee by the Corporation of debt securities of any subsidiary
of the Corporation if such guarantee ranks pari passu with, or junior in right
of payment to, the Junior Subordinated Debentures (other than (a) dividends or
distributions by the Corporation by way of issuance of its common stock, (b)
payments under the applicable Guarantee made by the Corporation in respect of
the Trust Securities of such Issuer Trust, (c) any declaration of a dividend in
connection with the implementation of a shareholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, and (d) purchases of common
stock related to the issuance of common stock or rights under any of the
Corporation's benefit plans). Certain United States federal income tax
consequences and special considerations applicable to any such Junior
Subordinated Debentures will be described in the applicable Prospectus
Supplement.

<PAGE>   57
 
  Enforcement of Certain Rights by Holders of Preferred Securities
 
     If an Event of Default with respect to a series of Corresponding Junior
Subordinated Debentures has occurred and is continuing and such event is
attributable to the failure of the Corporation to pay any amounts payable in
respect of such Corresponding Junior Subordinated Debentures on the date such
amounts are otherwise payable, a Holder of the Related Preferred Securities may
institute a legal proceeding directly against the Corporation for enforcement of
payment to such Holder of an amount equal to the amount payable in respect of
such Corresponding Junior Subordinated Debentures having a principal amount
equal to the aggregate liquidation amount of the Related Preferred Securities
held by such Holder (a "Direct Action"). The Corporation may not amend the
Junior Subordinated Indenture or the Corresponding Junior Subordinated
Debentures to remove the foregoing right to bring a Direct Action without the
prior written consent of the Holders of all of the Preferred Securities.
 
     The Holders of the Preferred Securities will not be able to exercise
directly any remedies available to the Holders of the Junior Subordinated
Debentures except under the circumstances described in the previous paragraph.
See "Description of Preferred Securities".
 
  Subordination
 
     The Junior Subordinated Debentures will be subordinate and junior in right
of payment, to the extent set forth therein and in the Junior Subordinated
Indenture, to all Debt of the Corporation other than Debt that expressly ranks
pari passu with, or junior in interest to, the Junior Subordinated Debentures
("Senior Indebtedness"). If the Corporation defaults in the payment of any
principal, premium, if any, or interest, if any, or any other amount payable on
any Senior Indebtedness when the same becomes due and payable, whether at
maturity or at a date fixed for redemption or by declaration of acceleration or
otherwise, then, unless and until such default has been cured or waived or has
ceased to exist or all Senior Indebtedness has been paid, no direct or indirect
payment (in cash, property, securities, by set-off or otherwise) may be made or
agreed to be made on the Junior Subordinated Debentures, or in respect of any
redemption, repayment, retirement, purchase or other acquisition of any of the
Junior Subordinated Debentures.
 
     In the event of (i) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceeding relating
to the Corporation, its creditors or its property, (ii) any proceeding for the
liquidation, dissolution or other winding up of the Corporation, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings,
(iii) any assignment by the Corporation for the benefit of creditors or (iv) any
other marshalling of the assets of the Corporation, all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made on account of the
Junior Subordinated Debentures. In such event, any payment or distribution on
account of the Junior Subordinated Debentures, whether in cash, securities or
other property, that would otherwise (but for the subordination provisions) be
payable or deliverable in respect of the Junior Subordinated Debentures will be
paid or delivered directly to the Holders of Senior Indebtedness in accordance
with the priorities then existing among such Holders until all Senior
Indebtedness (including any interest thereon accruing after the commencement of
any such proceedings) has been paid in full.
 
     In the event of any such proceeding, after payment in full of all sums
owing with respect to Senior Indebtedness, the Holders of Junior Subordinated
Debentures, together with the Holders of any obligations of the Corporation
ranking pari passu with the Junior Subordinated Debentures, will be entitled to
be paid from the remaining assets of the Corporation the amounts at the time due
and owing on the Junior Subordinated Debentures and such other obligations
before any payment or other distribution, whether in cash, property or
otherwise, will be made on account of any capital stock or obligations of the
Corporation ranking junior to the Junior Subordinated Debentures and such other
obligations. If any payment or distribution on account of the Junior
Subordinated Debentures of any character or any security, whether in cash,
securities or other property is received by any Holder of any Junior
Subordinated Debentures in contravention of any of the terms hereof and before
all the Senior Indebtedness has been paid in full, such payment or distribution
or security will be received in trust for the benefit of, and must be paid over
or delivered and transferred to, the Holders of the
 
                                       18
<PAGE>   58
 
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such Holders for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all such Senior
Indebtedness in full. By reason of such subordination, in the event of the
insolvency of the Corporation, Holders of Senior Indebtedness may receive more,
ratably, and Holders of the Junior Subordinated Debentures may receive less,
ratably, than the other creditors of the Corporation. Such subordination will
not prevent the occurrence of any Event of Default.
 
     The Junior Subordinated Indenture places no limitation on the amount of
additional Senior Indebtedness that may be incurred by the Corporation. The
Corporation expects from time to time to incur additional indebtedness
constituting Senior Indebtedness.
 
  Restrictions on Certain Payments
 
     The Corporation will not, as to each series of Junior Subordinated
Debentures, (i) declare or pay any dividends or distributions on, or prepay,
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Corporation's capital stock, (ii) make any payment of principal of, premium,
if any, or interest on, or repay, repurchase or redeem any debt securities of
the Corporation that rank pari passu with or junior in interest to the Junior
Subordinated Debentures, including other Junior Subordinated Debentures, or
(iii) make any guarantee payment with respect to any guarantee by the
Corporation of debt securities of any subsidiary of the Corporation if such
guarantee ranks pari passu with, or junior in right of payment to, the Junior
Subordinated Debentures (other than (a) dividends or distributions by the
Corporation by way of issuance of its common stock, (b) payments under the
applicable Guarantee made by the Corporation in respect of the Trust Securities
of such Issuer Trust, (c) any declaration of a dividend in connection with the
implementation of a shareholders' rights plan, or the issuance of stock under
any such plan in the future, or the redemption or repurchase of any such rights
pursuant thereto, and (d) purchases of common stock related to the issuance of
common stock or rights under any of the Corporation's benefit plans), if at such
time (i) there has occurred any event of which the Corporation has actual
knowledge that with the giving of notice or the lapse of time, or both, would
constitute an Event of Default with respect to the Junior Subordinated
Debentures of such series, (ii) if such Junior Subordinated Debentures are held
by an Issuer Trust, the Corporation is in default with respect to its payment of
any obligations under the Guarantee relating to the Related Preferred Securities
or (iii) the Corporation has given notice of its selection of an Extension
Period as provided in the Junior Subordinated Indenture with respect to the
Junior Subordinated Debentures of such series and has not rescinded such notice,
or such Extension Period, or any extension thereof, is continuing.
 
  Certain Covenants of the Corporation
 
     In the event Junior Subordinated Debentures are issued to an Issuer Trust
or Issuer Trustee thereof in connection with the issuance of Trust Securities of
such Issuer Trust, for so long as such Trust Securities remain outstanding, the
Corporation will covenant (i) to maintain, directly or indirectly, 100%
ownership of the Common Securities of such Issuer Trust, provided that certain
successors that are permitted pursuant to the Junior Subordinated Indenture may
succeed to the Corporation's ownership of the Common Securities, (ii) to use
commercially reasonable efforts, consistent with the terms and provisions of the
Declaration of Trust of such Issuer Trust to cause such Issuer Trust (a) to
remain a grantor trust, except in connection with a distribution of Junior
Subordinated Debentures to the Holders of the Trust Securities in liquidation of
the Issuer Trust, the redemption of all of the Trust Securities of an Issuer
Trust, or certain mergers, consolidations or amalgamations, each as permitted by
the Declaration of Trust of such Issuer Trust, and (b) to otherwise continue to
be classified as a grantor trust and not an association taxable as a corporation
for United States federal income tax purposes and (iii) not to cause, as Sponsor
of each Issuer Trust, or permit, as Holder of the Commons Securities, the
dissolution, winding-up or termination of such Issuer Trust except in connection
with a distribution of the Junior Subordinated Debentures as provided in the
Declaration of Trust of such Issuer Trust and in connection with certain
mergers, consolidations or amalgamations.

GOVERNING LAW
 
     Each Indenture and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of New York.
 
REGARDING THE INDENTURE TRUSTEE
 
     Harris Trust and Savings Bank is the trustee under each Indenture and has
been appointed by the Corporation as initial Security Registrar and Paying Agent
with regard to the Debt Securities. The Company has customary banking
relationships with the Indenture Trustee and certain of its affiliates in the
ordinary course of business.
 
                      DESCRIPTION OF PREFERRED SECURITIES
 
     Each Issuer Trust may issue only one series of Preferred Securities having
terms described in the Prospectus Supplement relating thereto. The Declaration
of Trust of each Issuer Trust will be qualified as an indenture under the Trust
Indenture Act. Harris Trust and Savings Bank will act as indenture trustee under
each Declaration of Trust. The Preferred Securities will represent undivided
beneficial ownership interests in the assets of the Issuer Trusts 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, as well as other benefits as described in the Declaration
of Trust. This Prospectus contains a description of all material provisions of
each Declaration of Trust. The summary of such provisions does not purport to be
complete; a copy of the form of such Declarations of Trust is filed as an
exhibit to the Registration Statement. All capitalized terms set forth below
have the meanings specified in the form of Declaration of Trust.
 
     The Preferred Securities will have such terms, including as to
Distributions, redemption, voting, liquidation rights and such other preferred,
deferred or other special rights or such restrictions as shall be set forth in
the Declaration of Trust of the Issuer Trust issuing such Preferred Securities
or made part of such Declaration by the Trust Indenture Act. Reference is made
to any Prospectus Supplement relating to the Preferred Securities of an Issuer
Trust for specific terms, including (i) the distinctive designation of such
Preferred Securities, (ii) the number of Preferred Securities issued by such
Issuer Trust, (iii) the annual Distribution rate (or method of determining such
rate) for Preferred Securities issued by such Issuer Trust and the date or dates
upon which such Distributions shall be payable, (iv) whether Distributions on
Preferred Securities issued by such Issuer Trust shall be cumulative, and, in
the case of Preferred Securities having such cumulative distribution rights, the
date or dates or method of determining the date or dates from which
distributions on Preferred Securities issued by such Issuer Trust shall be
cumulative, (v) the amount or amounts which shall be paid out of the assets of
such Issuer Trust to the Holders of Preferred Securities of such Issuer Trust
upon voluntary or involuntary dissolution, winding-up or termination of such
Issuer Trust, (vi) the obligation, if any, of such Issuer Trust to purchase or
redeem Preferred Securities issued by such Issuer Trust and the price or prices
at which, the period or periods within which and the terms and conditions upon
which Preferred Securities issued by such Issuer Trust shall be purchased or
redeemed, in whole or in part, pursuant to such obligation, (vii) the voting
rights, if any, of Preferred Securities issued by such Issuer Trust in addition
to those required by law, including the number of votes per Preferred Security
and any requirement for the approval by the Holders of Preferred Securities as a
condition to specified action or amendments to the Declaration of Trust of such
Issuer Trust, and (viii) any other relevant rights, preferences, privileges,
limitations or restrictions of Preferred Securities issued by such Issuer Trust,
consistent with the Declaration of Trust of such Issuer Trust and with
applicable law. All Preferred Securities offered hereby will be guaranteed by
the Corporation to the extent set forth below under "Description of Guarantees."
Certain United States federal income tax considerations applicable to any
offering of Preferred Securities will be described in the Prospectus Supplement
relating thereto.
 
     In connection with the issuance of Preferred Securities, each Issuer Trust
will issue one series of Common Securities, having such terms, including as to
Distributions, redemption, voting, liquidation rights or such restrictions, as
shall be set forth in the Declaration of Trust of the Issuer Trust issuing such
Common Securities or made part of such Declaration of Trust by the Trust
Indenture Act. The terms of the Common
                                       20
<PAGE>   60
 
Securities issued by such Issuer Trust will be substantially identical to the
terms of the Preferred Securities issued by such Issuer Trust. The Common
Securities will rank on a parity, and payments will be made thereon pro rata,
with such Preferred Securities except that upon a Trust Enforcement Event under
the Declaration of Trust of such Issuer Trust, the rights of the Holders of such
Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise will be subordinated to the rights of the
Holders of such Preferred Securities. Except in certain limited circumstances,
the Holders of Common Securities of an Issuer Trust will also be entitled to
vote and appoint, remove or replace any of the Issuer Trustees of such Issuer
Trust. All of the Common Securities of an Issuer Trust will be directly or
indirectly owned by the Corporation.
 
     If a Trust Enforcement Event with respect to a Declaration of Trust of any
Issuer Trust occurs and is continuing, then the Holders of Preferred Securities
of such Issuer Trust would rely on the enforcement by the Property Trustee of
its rights as a Holder of Junior Subordinated Debentures against the
Corporation. In addition, the Holders of a majority in liquidation amount of
such Preferred Securities will have the right to direct the time, method, and
place of conducting any proceeding for any remedy available to the Property
Trustee or to direct the exercise of any trust or power conferred upon the
Property Trustee under such Declaration of Trust, including the right to direct
the Property Trustee to exercise the remedies available to it as a Holder of
Junior Subordinated Debentures.
 
     An Event of Default under the Junior Subordinated Indenture that has
occurred and is continuing with respect to Corresponding Junior Subordinated
Debentures constitutes a "Trust Enforcement Event" under the Declaration of
Trust with respect to the Issuer Trust that issued the Related Preferred
Securities; provided that pursuant to such Declaration, the Holder of the Common
Securities will be deemed to have waived any Trust Enforcement Event with
respect to the Common Securities until all Trust Enforcement Events with respect
to the Related Preferred Securities have been cured, waived or otherwise
eliminated. Until such Trust Enforcement Event with respect to the Related
Preferred Securities has been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Related Preferred Securities and only the Holders of the Related Preferred
Securities will have the right to direct the Property Trustee with respect to
certain matters under such Declaration of Trust, and therefore the Junior
Subordinated Indenture.
 
     Upon the occurrence of a Trust Enforcement Event, the Property Trustee, as
the Holder of Corresponding Junior Subordinated Debentures, will have the right
under the Junior Subordinated Indenture to declare the principal of and premium,
if any, and interest on such Junior Subordinated Debentures to be immediately
due and payable.
 
     If the Property Trustee fails to enforce its rights with respect to Junior
Subordinated Debentures, any Holder of Preferred Securities may, to the extent
permitted by applicable law, institute a legal proceeding directly against the
Corporation to enforce the Property Trustee's rights under such Junior
Subordinated Debentures without first instituting any legal proceeding against
the Property Trustee or any other person or entity. In addition, if a Trust
Enforcement Event has occurred and is continuing and such event is attributable
to the failure of the Corporation to pay principal of and premium, if any, and
interest or other required payments on Junior Subordinated Debentures on the
date such interest, principal or other payment is otherwise payable, then a
Holder of Preferred Securities of such Issuer Trust may, on or after the
respective due dates specified in such Junior Subordinated Debentures, institute
a Direct Action. In connection with such Direct Action, the rights of the
Corporation will be subrogated to the rights of such Holder of Preferred
Securities under such Declaration of Trust to the extent of any payment made by
the Corporation to such Holder of Preferred Securities in such Direct Action.
Consequently, the Corporation will be entitled to payment of amounts that a
Holder of Preferred Securities receives in respect of an unpaid distribution
that resulted in the bringing of a Direct Action to the extent that such Holder
receives or has already received full payment with respect to such unpaid
distribution from an Issuer Trust. The Holders of Preferred Securities of an
Issuer Trust will not be able to exercise directly any other remedy available to
the Holders of Junior Subordinated Debentures.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The following description of the Corporation's capital stock does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the more complete descriptions thereof set forth in the
Corporation's Restated Certificate of Incorporation, as amended (the
"Certificate"), and By-laws, as amended (the "By-laws") which documents are
exhibits to this Registration Statement.
 
     The Corporation is authorized to issue up to 80,000,000 shares of Common
Stock, par value $1.00, and up to 1,500,000 shares of Preferred Stock, no par
value. As of March 27, 1998 there were 40,734,864 shares of Common Stock and no
shares of Preferred Stock outstanding. Of the 1,500,000 shares of authorized
Preferred Stock, 400,000 shares have been reserved and designated as "Series A
Junior Participating Preferred Stock."
 
PREFERRED STOCK
 
     General.  The following summary contains a description of certain general
terms of the Preferred Stock. The particular terms of any series of Preferred
Stock that may be offered will be described in the applicable Prospectus
Supplement. If so indicated in a Prospectus Supplement, the terms of any such
series may differ from the terms set forth below. The summary of terms of the
Preferred Stock does not purport to be complete and is subject to and qualified
in its entirety by reference to the provisions of the Certificate and the
Certificate of Designation (the "Certificate of Designation") relating to a
particular series of offered Preferred Stock which is or will be in the form
filed or incorporated by reference as an exhibit to the Registration Statement
at or prior to the time of the issuance of such series of Preferred Stock.
 
     The Board of Directors has the power, without further action by the
shareholders, to issue Preferred Stock in one or more series, with such
designations or titles, dividend rates, redemption provisions, special or
relative rights in the event of liquidation, dissolution, distribution or
winding up of the Corporation, sinking fund provisions, conversion provisions,
voting rights thereof and other preferences, privileges, powers, rights,
qualifications, limitations and restrictions, as shall be set forth as and when
established by the Board of Directors; provided that the Board of Directors
shall fix such provisions as will, at a minimum, entitle the Holders of such
Preferred Stock, voting as a class, to elect at least two directors upon default
of the equivalent of six quarterly dividends, such right to continue until
cumulative dividends have been paid in full, or until non-cumulative dividends
have been paid regularly for at least a year, and require the affirmative
approval of at least two-thirds of the outstanding Preferred Stock as a
prerequisite to any amendment to the Certificate or By-laws altering materially
any existing provision of such Preferred Stock. The shares of any series of
Preferred Stock will be, when issued, fully paid and non-assessable and Holders
thereof will have no preemptive rights in connection therewith.
 
     Rank.  Any series of Preferred Stock will, with respect to rights on
liquidation, winding up and dissolution, rank (i) senior to all classes of
Common Stock and to all equity securities issued by the Corporation, the terms
of which specifically provide that such equity securities will rank junior to
such series of Preferred Stock (the "Junior Liquidation Securities"); (ii) on a
parity with all equity securities issued by the Corporation, the terms of which
specifically provide that such equity securities will rank on a parity with such
series of Preferred Stock ("Parity Liquidation Securities"); and (iii) junior to
all equity securities issued by the Corporation, the terms of which specifically
provide that such equity securities will rank senior to such series of Preferred
Stock (the "Senior Liquidation Securities"). In addition, any series of
Preferred Stock will, with respect to dividend rights, rank (i) senior to all
equity securities issued by the Corporation, the terms of which specifically
provide that such equity securities will rank junior to such series of Preferred
Stock and, to the extent provided in the applicable Certificate of Designation,
to Common Stock; (ii) on a parity with all equity securities issued by the
Corporation, the terms of which specifically provide that such equity securities
will rank on a parity with such series of Preferred Stock and, to the extent
provided in the applicable Certificate of Designation, to Common Stock ("Parity
Dividend Securities"); and (iii) junior to all equity securities issued by the
Corporation, the terms of which specifically provide that such equity securities
will
 
                                       22
<PAGE>   62
 
rank senior to such series of Preferred Stock. As used in any Certificate of
Designation for these purposes, the term "equity securities" will not include
debt securities convertible into or exchangeable for equity securities.
 
     Dividends.  Holders of each series of Preferred Stock will be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available therefor, cash dividends at such rates and on such dates as are set
forth in the Prospectus Supplement relating to such series of Preferred Stock.
Dividends will be payable to Holders of Preferred Stock as they appear on the
books of the Corporation (or, if applicable, the records of the Depositary
referred to below under "-- Depositary Shares") on such record dates as shall be
fixed by the Board of Directors. Dividends on any series of Preferred Stock may
be cumulative or non-cumulative.
 
     No full dividends may be declared or paid out of funds set apart for the
payment of dividends on any series of Preferred Stock unless dividends shall
have been paid or set apart for such payment on the Parity Dividend Securities.
If full dividends are not so paid, such series of Preferred Stock shall share
dividends pro rata with the Parity Dividend Securities.
 
     Conversion and Exchange.  The Prospectus Supplement for any series of
Preferred Stock will state the terms, if any, on which shares of that series are
convertible into shares of another series of Preferred Stock or Common Stock or
exchangeable for another series of Preferred Stock, Common Stock or Debt
Securities of the Corporation.
 
     Redemption.  A series of Preferred Stock may be redeemable at any time, in
whole or in part, at the option of the Corporation or the Holder thereof and may
be subject to mandatory redemption pursuant to a sinking fund or otherwise upon
terms and at the redemption prices set forth in the Prospectus Supplement
relating to such series.
 
     In the event of partial redemptions of Preferred Stock, whether by
mandatory or optional redemption, the shares to be redeemed will be determined
by lot or pro rata, as may be determined by the Board of Directors, or by any
other method determined to be equitable by the Board of Directors.
 
     On and after a redemption date, unless the Corporation defaults in the
payment of the redemption price, dividends will cease to accrue on shares of
Preferred Stock called for redemption and all rights of Holders of such shares
will terminate except for the right to receive the redemption price.
 
     Liquidation Preference.  Upon any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, Holders of each series of
Preferred Stock that ranks senior to the Junior Liquidation Securities will be
entitled to receive out of assets of the Corporation available for distribution
to shareholders, before any distribution is made on any Junior Liquidation
Securities, including Common Stock, distributions upon liquidation in the amount
set forth in the Prospectus Supplement relating to such series of Preferred
Stock. If the Holders of the Preferred Stock of any series and any other Parity
Liquidation Securities are not paid in full, the Holders of the Preferred Stock
of such series and the Parity Liquidation Securities will share ratably in any
such distribution of assets of the Corporation in proportion to the full
liquidation preferences to which each is entitled. After payment of the full
amount of the liquidation preference to which they are entitled, the Holders of
such series of Preferred Stock will not be entitled (unless the applicable
Prospectus Supplement indicates otherwise) to any further participation in any
distribution of assets of the Corporation. The liquidation preference of any
series of Preferred Stock is not necessarily indicative of the price at which
shares of such series of Preferred Stock will actually trade at or after the
time of their issuance.
 
     Voting Rights.  Except as indicated in the Prospectus Supplement relating
to a particular series of Preferred Stock as specified under "-- General" above,
or except as expressly required by applicable law or the Certificate, the
Holders of shares of Preferred Stock will have no voting rights.
 
     Preferred Share Purchase Rights.  On September 22, 1987, the Corporation's
Board of Directors declared a dividend distribution of one Preferred Share
Purchase Right (a "Right") on each share of the Common Stock outstanding as of
October 2, 1987 and adopted the Rights Agreement, dated as of October 22, 1987
(the "Rights Agreement"). On September 30, 1997, the Board of Directors amended
and restated the Rights Agreement. Each Right allows the shareholder to purchase
1/100th of a share of a new series of
 
                                       23
<PAGE>   63
 
preferred stock of the Corporation at an exercise price of $175. Rights are
exercisable only if a person or group acquires 20% or more of the Common Stock
or announces a tender offer the consummation of which would result in ownership
by a person or group of 20% or more of the Common Stock. The Rights, which do
not have the right to vote or receive dividends, expire on October 2, 2007 and
may be redeemed, prior to becoming exercisable, by the Board of Directors at
$.02 per Right or by shareholder action with an acquisition proposal.
 
     If any person or group acquires 20% or more of the outstanding Common
Stock, the "flip-in" provision of the Rights will be triggered and the Rights
will entitle a Holder (other than such person or any member of such group) to
acquire a number of additional shares of the Corporation's common stock having a
market value of twice the exercise price of each Right.
 
     In the event the Corporation is involved in a merger or other business
combination transaction, each Right will entitle its Holder to purchase, at the
Right's then-current exercise price, a number of the acquiring company's common
stock having a market value at that time of twice the Rights' exercise price.
 
     The existence of the Rights Plan and the Rights may, under certain
circumstances discourage, delay or prevent a change in control of the
Corporation.
 
DEPOSITARY SHARES
 
     The description set forth below of certain provisions of the Deposit
Agreement (as defined below) and of the Depositary Shares and Depositary
Receipts (as defined below) does not purport to be complete and is subject to
and qualified in its entirety by reference to the forms of Deposit Agreement and
Deposit Receipt, included as exhibits to the Registration Statement.
 
     General.  The Corporation may, at its option, elect to offer fractional
shares of Preferred Stock, rather than full shares of Preferred Stock. In the
event the Corporation so elects, the Depositary will issue receipts for
Depositary Shares, each of which will represent a fraction (to be set forth in
the Prospectus Supplement relating to a particular series of Preferred Stock) of
a share of a particular series of Preferred Stock as described below.
 
     The shares of any series of Preferred Stock represented by Depositary
Shares will be deposited under a Deposit Agreement (the "Deposit Agreement")
between the Corporation and a depositary that is a bank or trust company having
its principal offices in the United States and having a combined capital surplus
of at least the amount set forth in the Deposit Agreement (the "Depositary").
Subject to the terms of the Deposit Agreement, each owner of a Depositary Share
will be entitled, in proportion to the applicable fraction of a share of
Preferred Stock represented by such Depositary Share, to all the rights and
preferences of the Preferred Stock represented thereby (including dividend,
voting, redemption, conversion and liquidation rights).
 
     The Depositary Shares will be evidenced by depositary receipts issued
pursuant to the Deposit Agreement (the "Depositary Receipts"). The Depositary
Receipts will be distributed to those persons purchasing the fractional shares
of Preferred Stock in accordance with the terms of the offering.
 
     Pending the preparation of definitive Depositary Receipts, the Depositary
shall, upon the written order of the Corporation or any Holder of deposited
Preferred Stock, execute and deliver temporary Depositary Receipts which are
substantially identical to, and entitle the Holders thereof to all the rights
pertaining to, the definitive Depositary Receipts. Depositary Receipts will be
prepared thereafter without unreasonable delay, and temporary Depositary
Receipts will be exchangeable for definitive Depositary Receipts at the
Corporation's expense.
 
     Dividends and Other Distributions.  The Depositary will distribute all cash
dividends or other cash distributions received in respect of the deposited
Preferred Stock to the record Holders of the Depositary Shares relating to such
Preferred Stock in proportion to the number of such Depositary Shares owned by
such Holders.
 
     In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record Holders of Depositary Shares
entitled thereto. If the Depositary determines that it is not feasible to
                                       24
<PAGE>   64
 
make such distribution, it may, with the approval of the Corporation, sell such
property and distribute the net proceeds from such sale to such Holders.
 
     Redemption of Stock.  If a series of Preferred Stock represented by
Depositary Shares is to be redeemed, the Depositary Shares will be redeemed from
the proceeds received by the Depositary resulting from the redemption, in whole
or in part, of such series of Preferred Stock held by the Depositary. The
Depositary Shares will be redeemed by the Depositary at a price per Depositary
Share equal to the applicable fraction of the redemption price per share payable
in respect of the shares of Preferred Stock so redeemed. If fewer than all the
Depositary Shares will be redeemed, the Depositary Shares to be redeemed will be
selected by the Depositary by lot or pro rata or by any other equitable method
as may be determined by the Depositary.
 
     Voting Deposited Preferred Stock.  Upon receipt of notice of any meeting at
which the Holders of any series of deposited Preferred Stock are entitled to
vote, the Depositary will mail the information contained in such notice of
meeting to the record Holders of the Depositary Shares relating to such series
of Preferred Stock. Each record Holder of such Depositary Shares on the record
date (which will be the same date as the record date for the relevant series of
Preferred Stock) will be entitled to instruct the Depositary as to the exercise
of the voting rights pertaining to the amount of the Preferred Stock represented
by such Holder's Depositary Shares. The Depositary will endeavor, insofar as
practicable, to vote the amount of such series of Preferred Stock represented by
such Depositary Shares in accordance with such instructions, and the Corporation
will agree to take all reasonable actions that may be deemed necessary by the
Depositary in order to enable the Depositary to do so. The Depositary will
abstain from voting shares of the Preferred Stock to the extent it does not
receive specific instructions from the Holder of Depositary Shares representing
such Preferred Stock.
 
     Amendment and Termination of the Deposit Agreement.  The form of the
Depositary Receipt evidencing the Depositary Shares and any provision of the
Deposit Agreement may at any time be amended by agreement between the
Corporation and the Depositary. However, any amendment which materially
prejudices any substantial right of the Holders of the Depositary Shares
representing Preferred Stock of any series will not be effective unless such
amendment has been approved by the record Holders of a majority of the
Depositary Shares then outstanding. Every Holder of an outstanding Depositary
Receipt at the time any such amendment becomes effective shall be deemed, by
continuing to hold such Depositary Receipt to consent and agree to such
amendment and to be bound by the Deposit Agreement as amended thereby. The
Deposit Agreement may be terminated by the Corporation or by the Depositary only
after (i) all outstanding Depositary Shares have been redeemed; or (ii) each
share of Preferred Stock has been converted into other Preferred Stock or Common
Stock or has been exchanged for Debt Securities; or (iii) there has been a final
distribution in respect of the Preferred Stock in connection with any
liquidation, dissolution or winding up of the Corporation and such distribution
has been distributed to the Holders of Depositary Shares.
 
     Charges of Depositary.  The Corporation will pay all transfer and other
taxes and governmental charges arising solely from the existence of the
depositary arrangements. The Corporation will pay all charges of the Depositary
in connection with the initial deposit of the relevant series of Preferred Stock
and any redemption of such Preferred Stock. Holders of Depositary Receipts will
pay other transfer and other taxes and governmental charges and such other
charges or expenses as are expressly provided in the Deposit Agreement to be for
their accounts.
 
     Resignation and Removal of Depositary.  The Depositary may resign at any
time by delivering to the Corporation notice of its election to do so, and the
Corporation may at any time remove the Depositary, any such resignation or
removal to take effect upon the appointment of a successor Depositary and its
acceptance of such appointment. Such successor Depositary must be appointed
within 60 days after delivery of the notice of resignation or removal and must
be a bank or trust company having its principal office in the United States and
having a combined capital and surplus of at least the amount set forth in the
Deposit Agreement.
 
     Miscellaneous.  The Depositary will forward all reports and communications
from the Corporation that are delivered to the Depositary and that the
Corporation is required to furnish to the Holders of the deposited Preferred
Stock.
 
                                       25
<PAGE>   65
 
     Neither the Depositary nor the Corporation will be liable if it is
prevented or delayed by law or any circumstances beyond its control in
performing its obligations under the Deposit Agreement. The obligations of the
Depositary under the Deposit Agreement will be limited to performance in good
faith of its duties thereunder, and it will not be obligated to prosecute or
defend any legal proceeding in respect of any Depositary Shares, Depositary
Receipts or shares of Preferred Stock unless satisfactory indemnity is
furnished. The Depositary may rely upon written advice of counsel or
accountants, or upon information provided by Holders of Depositary Receipts or
other persons believed to be competent and on documents believed to be genuine.
 
COMMON STOCK
 
     Each Holder of Common Stock is entitled to one vote for each share owned of
record on all matters voted upon by shareholders, and a majority vote is
required for all action to be taken by shareholders except for certain
transactions described in the Certificate and in the New York Business
Corporation Law. See "Corporate Provisions." In the event of a liquidation,
dissolution or winding up of the Corporation, the Holders of Common Stock are
entitled to share equally and ratably in the assets of the Corporation, if any,
remaining after the payment of all debts and liabilities of the Corporation and
the liquidation preference of any outstanding Preferred Stock. The Holders of
the Common Stock have no preemptive rights or cumulative voting rights and there
are no redemption, sinking fund or conversion provisions applicable to the
Common Stock.
 
     Holders of Common Stock are entitled to receive dividends if, as and when
declared by the Board of Directors out of funds legally available for such
purpose, subject to the dividend and liquidation rights of any Preferred Stock
that may be issued and subject to restrictions and limitations that may be
contained in the Corporation's loan agreements. See "-- Preferred
Stock -- Preferred Share Purchase Rights."
 
                            DESCRIPTION OF WARRANTS
 
GENERAL
 
     The Corporation may issue together with other Securities or separately,
warrants for the purchase of (i) Debt Securities ("Debt Warrants"), (ii) Common
Stock ("Common Stock Warrants") or (iii) Preferred Stock ("Preferred Stock
Warrants"). The Corporation may also issue, together with Debt Securities or
Debt Warrants or separately, currency warrants ("Currency Warrants" and together
with Debt Warrants, Common Stock Warrants, the "Warrants") either in the form of
Currency Put Warrants or Currency Call Warrants (as defined below).
 
     The Warrants are to be issued under agreements ("Warrant Agreements") to be
entered into between the Corporation and a bank or trust company, as agent, all
to be set forth in the applicable Prospectus Supplement relating to any or all

CURRENCY WARRANTS
 
     The Corporation may issue, together with Debt Securities or Debt Warrants
or separately, Currency Warrants either in the form of "Currency Put Warrants"
entitling the Holders thereof to receive from the Corporation the Cash
Settlement Value in U.S. dollars of the right to sell a specified amount of a
specified foreign currency or currency units for a specified amount of U.S.
dollars, or in the form of "Currency Call Warrants" entitling the Holders
thereof to receive from the Corporation the Cash Settlement Value in U.S.
dollars of the right to purchase a specified amount of a specified foreign
currency or currency units for a specified amount of U.S. dollars. The spot
exchange rate of the applicable Base Currency, upon exercise, as compared to the
U.S. dollar, will determine whether the Currency Warrants have a Cash Settlement
Value on any given day prior to their expiration.
 
     General.  Reference is made to the applicable Prospectus Supplement for the
terms of Currency Warrants in respect of which this Prospectus is being
delivered, the Currency Warrant Agreement relating to such Currency Warrants and
the Currency Warrant Certificates representing such Currency Warrants, including
the following: (1) whether such Currency Warrants will be Currency Put Warrants,
Currency Call Warrants, or both; (2) the formula for determining the Cash
Settlement Value, if any, of each Currency Warrant; (3) the procedures and
conditions relating to the exercise of such Currency Warrants; (4) the
circumstances which will cause the Currency Warrants to be deemed to be
automatically exercised; (5) any minimum number of Currency Warrants which must
be exercised at any one time, other than upon automatic exercise; and (6) the
date on which the right to exercise such Currency Warrants will commence and the
date on which such right will expire.
 
     Book-Entry Procedures and Settlement.  Except as may otherwise be provided
in the applicable Prospectus Supplement, the Currency Warrants will be issued in
the form of Global Currency Warrant Certificates, registered in the name of a
depositary or its nominee. Holders will not be entitled to receive definitive
certificates representing Currency Warrants. A Holder's ownership of a Currency
Warrant will be recorded on or through the records of the brokerage firm or
other entity that maintains such Holder's account. In turn, the total number of
Currency Warrants held by an individual brokerage firm for its clients will be
maintained on the records of the depositary in the name of such brokerage firm
or its agent. Transfer of ownership of any Currency Warrant will be effected
only through the selling Holder's brokerage firm.
 
     Exercise of Currency Warrants.  Each Currency Warrant will entitle the
Holder to receive the Cash Settlement Value of such Currency Warrant on the
applicable Exercise Date, in each case as such terms will be defined in the
applicable Prospectus Supplement. If not exercised prior to 3:00 p.m., New York
City time, on the fifth New York Business Day preceding the expiration date,
Currency Warrants will be deemed automatically exercised on the expiration date.
 
                           DESCRIPTION OF GUARANTEES
 
     A guarantee (each, a "Guarantee") will be executed and delivered by the
Corporation concurrently with the issuance by an Issuer Trust of Preferred
Securities for the benefit of the Holders from time to time of such Preferred
Securities. Each Guarantee will be qualified as an indenture under the Trust
Indenture Act. Harris Trust and Savings Bank will act as indenture trustee under
each Guarantee (the "Guarantee Trustee"). This Prospectus contains a description
of all material provisions of each Guarantee. The summary of such provisions
does not purport to be complete; a copy of the form of such Guarantees is filed
as an exhibit to the Registration Statement. All capitalized terms set forth
below have the meanings specified in the form of Guarantee. The Guarantee
Trustee will hold each Guarantee for the benefit of the Holders of the Preferred
Securities of an Issuer Trust.
 
                                       29
<PAGE>   69
 
GENERAL
 
     Pursuant to and to the extent set forth in each Guarantee, and except as
otherwise set forth in the applicable Prospectus Supplement, the Corporation
will irrevocably and unconditionally agree to pay in full 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 such Issuer
Trust may have or assert. The following payments or Distributions with respect
to the Preferred Securities, to the extent not paid by or on behalf of such
Issuer Trust (the "Guarantee Payments"), will be subject to such Guarantee: (i)
any accumulated and unpaid Distributions required to be paid on such Preferred
Securities, to the extent that such Issuer Trust has sufficient funds available
therefor at the time, (ii) the Redemption Price with respect to any Preferred
Securities called for redemption, to the extent that such Issuer Trust has
sufficient funds available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding up or liquidation of such Issuer Trust (other
than in connection with the distribution of Junior Subordinated Debentures to
the Holders of Trust Securities as provided in the Declaration of Trust), the
lesser of (a) the aggregate liquidation amount of the Preferred Securities and
all accumulated and unpaid Distributions thereon to the date of payment and (b)
the amount of assets of such Issuer Trust remaining available for distribution
to Holders of such Preferred Securities. The Corporation's obligation to make a
Guarantee Payment may be satisfied by direct payment of the required amounts by
the Corporation to the Holders of the applicable Preferred Securities or by
causing such Issuer Trust to pay such amounts to such Holders.
 
     Each Guarantee will apply only to the extent that the applicable Issuer
Trust has sufficient funds available to make such payments. If the Corporation
does not make interest payments on Junior Subordinated Debentures held by an
Issuer Trust, such Issuer Trust will not be able to pay Distributions on the
Preferred Securities issued by such Issuer Trust and will not have funds legally
available therefor.
 
     The Corporation will also irrevocably and unconditionally guarantee the
obligations of any Issuer Trust with respect to such Issuer Trust's Common
Securities to the same extent as the Guarantee of the Preferred Securities of
such Issuer Trust, except that upon the occurrence and the continuation of a
Trust Enforcement Event with respect to such Issuer Trust, Holders of such
Preferred Securities shall have a priority over Holders of such Common
Securities with respect to Distributions and payments on liquidation, redemption
or otherwise.
 
     The Corporation will, through the Declarations of Trust, the Guarantees,
the Expense Agreements (as defined under "Description of Expense Agreements"),
the Junior Subordinated Debentures and the Junior Subordinated Indenture, taken
together, fully and unconditionally guarantee each Issuer Trust's obligations
under the Preferred Securities of such Issuer Trust. 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 and unconditional guarantee of each
Issuer Trust's obligations under the Preferred Securities of such Issuer Trust.
 
STATUS OF THE GUARANTEES
 
     Each Guarantee will constitute an unsecured obligation of the Corporation
and will rank (i) subordinate and junior in right of payment to all other
liabilities of the Corporation, (ii) on a parity with the most senior preferred
or preference stock now or hereafter issued by the Corporation and with any
guarantee now or hereafter entered into by the Corporation in respect of any
preferred securities of any affiliate of the Corporation and (iii) senior to the
Corporation's common stock. The Guarantees will not place a limitation on the
amount of additional Senior Indebtedness that may be incurred by the
Corporation.
 
     Each Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the Corporation to enforce its rights under a Guarantee without first
instituting a legal proceeding against any other person or entity). Each such
Guarantee will not be discharged except by payment of the Guarantee Payments in
full to the extent not paid by the applicable Issuer Trust or upon distribution
of Junior Subordinated Debentures to the Holders of the applicable Preferred
Securities in exchange for all such Preferred Securities.

<PAGE>   70
 
CERTAIN COVENANTS OF THE CORPORATION
 
     In each Guarantee, the Corporation will covenant that, so long as any Trust
Securities issued by the applicable Issuer Trust remain outstanding, if (i)
there shall have occurred any Event of Default under the Junior Subordinated
Indenture with respect to the applicable series of Junior Subordinated
Debentures held by such Issuer Trust, (ii) the Corporation shall be in default
with respect to its payment of any obligations under such Guarantee or (iii) the
Corporation shall have given notice of its election of an Extension Period as
provided in the certificate evidencing such Junior Subordinated Debentures and
shall not have rescinded such notice, or such Extension Period or any extension
thereof shall be continuing, then the Corporation will not, and will not permit
any subsidiary to, (x) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Corporation's capital stock or (y) make any payment of principal, interest
or premium, if any, on or repay, repurchase or redeem any debt securities of the
Corporation that rank on a parity with or junior in interest to Junior
Subordinated Debentures or (z) make any guarantee payments with respect to any
guarantee by the Corporation of the debt securities of any subsidiary of the
Corporation if such guarantee ranks pari passu with, or junior in interest to,
such Junior Subordinated Debentures (other than (a) dividends or distributions
by the Corporation by way of issuance of its common stock, (b) payments under
the applicable Guarantee made by the Corporation in respect of the Trust
Securities of such Issuer Trust, (c) any declaration of a dividend in connection
with the implementation of a shareholders' rights plan, or the issuance of stock
under any such plan in the future, or the redemption or repurchase of any such
rights pursuant thereto, and (d) purchases of common stock related to the
issuance of common stock or rights under any of the Corporation's benefit
plans).
 
AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes that do not materially adversely affect
the rights of Holders of Preferred Securities to which a Guarantee relates (in
which case no consent of such Holders will be required), a Guarantee may not be
amended without the prior approval of the Holders of not less than 66 2/3% of
the aggregate liquidation amount of the outstanding Preferred Securities to
which a Guarantee relates. The manner of obtaining any such approval will be as
set forth in an accompanying Prospectus Supplement. All guarantees and
agreements contained in a Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Corporation and shall inure to
the benefit of the Holders of such Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
     An event of default under a Guarantee will occur upon the failure of the
Corporation to perform any of its payment or other obligations thereunder. The
Holders of not less than a majority in aggregate liquidation amount of the
Preferred Securities to which a Guarantee relates 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 the Guarantee or to direct the exercise of
any trust or power conferred upon the Guarantee Trustee under such Guarantee.
 
     If the Guarantee Trustee fails to enforce a Guarantee, then any Holder of
Preferred Securities to which such Guarantee relates may institute a legal
proceeding directly against the Corporation to enforce the Guarantee Trustee's
rights under such Guarantee, without first instituting a legal proceeding
against the Issuer Trust that issued such Preferred Securities, the Guarantee
Trustee or any other person or entity.
 
     The Corporation, as guarantor, will be required to file annually with the
Guarantee Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under any
outstanding Guarantees.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by the Corporation in performance of a Guarantee, undertakes to
perform only such duties as are specifically set forth in the Guarantee and,
after default with respect to a Guarantee (that has not been cured or waived)
that is
                                       31
<PAGE>   71
 
actually known to a responsible officer of the Guarantee Trustee, must exercise
the same degree of care and skill as a prudent person would exercise or use
under the circumstances 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 Preferred
Securities to which such Guarantee relates unless it is offered reasonable
indemnity against the costs, expenses and liabilities that might be incurred
thereby.
 
TERMINATION OF THE GUARANTEES
 
     Each Guarantee will terminate as to the Preferred Securities issued by an
Issuer Trust and be of no further force and effect upon full payment of the
Redemption Price of all Preferred Securities of such Issuer Trust, upon full
payment of the amounts payable upon liquidation of such Issuer Trust or upon
distribution of Junior Subordinated Debentures held by such Issuer Trust to the
Holders of the Preferred Securities of such Issuer Trust in exchange for all of
the Preferred Securities of such Issuer Trust. Each Guarantee will continue to
be effective or will be reinstated, as the case may be, if at any time any
Holder of related Preferred Securities issued by an Issuer Trust must restore
payment of any sums paid under such Preferred Securities or such Guarantee.
 
GOVERNING LAW
 
     The Guarantees will be governed by and construed and interpreted in
accordance with the laws of the State of New York.
 
                       DESCRIPTION OF EXPENSE AGREEMENTS
 
     Pursuant to the Agreements as to Expenses and Liabilities entered into by
the Corporation and each Issuer Trust (each, an "Expense Agreement"), the
Corporation will, as Sponsor, irrevocably and unconditionally guarantee to each
person or entity to whom the applicable Issuer Trust becomes indebted or liable,
the full payment of any costs, expenses or liabilities of such Issuer Trust,
other than obligations of such Issuer Trust to pay to the Holders of its Trust
Securities the amounts distributable to such Holders pursuant to the terms of
such Trust Securities. Each Expense Agreement will constitute an unsecured
obligation of the Corporation and will rank subordinate and junior in right of
payment to all liabilities of the Corporation in the same manner as the
Guarantees.
 
                RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE
               CORRESPONDING JUNIOR SUBORDINATED DEBENTURES, THE
                     GUARANTEES AND THE EXPENSE AGREEMENTS
 
FULL AND UNCONDITIONAL GUARANTEE
 
     Payments of Distributions and other amounts due on the Preferred Securities
of any Issuer Trust (to the extent such Issuer Trust has funds available for
such payment) are irrevocably guaranteed by the Corporation as and to the extent
set forth under "Description of Guarantees". Taken together, the Corporation's
obligations under each series of Corresponding Junior Subordinated Debentures,
the Junior Subordinated Indenture, the related Declaration of Trust, the related
Expense Agreement and the related Guarantee provide, in the aggregate, a full,
irrevocable and unconditional guarantee on a subordinated basis 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 such Issuer Trust's obligations in
respect of the Related Preferred Securities. If and to the extent that the
Corporation does not make payments on the Corresponding Junior Subordinated
Debentures held by any Issuer Trust, such Issuer Trust will not have sufficient
funds to pay Distributions or other amounts due on its Related Preferred
Securities. The Guarantees do not cover payment of amounts payable with respect
to an Issuer Trust's Preferred Securities when such Issuer Trust does not have
sufficient
                                       32
<PAGE>   72
 
funds to pay such amounts. In such event, the remedy of a Holder of Preferred
Securities is to institute a Direct Action against the Corporation for
enforcement of payment of the Corporation's obligations under Corresponding
Junior Subordinated Debentures having a principal amount equal to the
liquidation amount of the Preferred Securities held by such Holder.
 
     The obligations of the Corporation under the Junior Subordinated
Debentures, each Guarantee and each Expense Agreement are subordinate and junior
in right of payment to all Senior Indebtedness of the Corporation.
 
SUFFICIENCY OF PAYMENTS
 
     As long as payments are made when due on each series of Corresponding
Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments distributable on the Related 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 Related Preferred Securities and
related 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, Distribution dates and other payment dates for the
Related Preferred Securities; (iii) the Corporation will pay for all and any
costs, expenses and liabilities of each Issuer Trust except such Issuer Trust's
obligations to Holders of its Trust Securities; and (iv) each Declaration of
Trust further provides that the Issuer Trust will not engage in any activity
that is not consistent with the limited purposes of such Issuer Trust.
 
     Notwithstanding anything to the contrary in the Junior Subordinated
Indenture, the Corporation has the right to set off any payment it is otherwise
required to make thereunder against and to the extent the Corporation has
theretofore made, or is concurrently on the date of such payment making, a
payment under the related Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
 
     A Holder of any Preferred Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the related
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, the related Issuer Trust or any other person or entity. See
"Description of Guarantee".
 
     A default or event of default under any Debt (other than the Corresponding
Junior Subordinated Debentures) of the Corporation would not constitute a
default or Event of Default in respect of the Related Preferred Securities.
However, in the event of payment defaults under, or acceleration of, Senior
Indebtedness of the Corporation, the subordination provisions of the Junior
Subordinated Indenture and the Junior Subordinated Debentures provide that no
payments may be made in respect of any Junior Subordinated Debentures until such
Senior Indebtedness has been paid in full or any payment default thereunder has
been cured or waived. See "Description of Debt Securities -- Description of
Junior Subordinated Debentures -- Subordination." Failure to make required
payments on any series of Corresponding Junior Subordinated Debentures would
constitute an Event of Default with respect to such series under the Junior
Subordinated Indenture.
 
LIMITED PURPOSE OF ISSUER TRUSTS
 
     Each Issuer Trust's Preferred Securities represent preferred undivided
beneficial interests in the assets of such Issuer Trust, and each Issuer Trust
exists for the sole purpose of issuing its Preferred Securities and Common
Securities, investing the proceeds thereof in Corresponding Junior Subordinated
Debentures and engaging in only those other activities necessary or incidental
thereto. 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 is entitled to receive
from the Corporation payments on Corresponding Junior Subordinated Debentures
held, while a Holder of Preferred Securities is entitled to receive
Distributions or other amounts distributable with respect to the Preferred
Securities from
 
                                       33
<PAGE>   73
 
such Issuer Trust (or from the Corporation under the related Guarantee) only if
and to the extent such Issuer Trust has funds available for the payment of such
Distributions.
 
RIGHTS UPON TERMINATION
 
     Upon any voluntary or involuntary dissolution, winding-up or liquidation of
any Issuer Trust, other than any such dissolution, winding-up or liquidation
involving the distribution of the Corresponding Junior Subordinated Debentures,
after satisfaction of liabilities to creditors of the Issuer Trust as required
by applicable law, the Holders of the Related Preferred Securities will be
entitled to receive, out of the assets held by such Issuer Trust, the
Liquidation Distribution (as defined in the relevant Declaration of Trust) in
cash. See "Description of Preferred Securities". Upon any voluntary or
involuntary liquidation or bankruptcy of the Corporation, the Property Trustee,
as the Holder of the Corresponding Junior Subordinated Debentures, would be a
subordinated creditor of the Corporation, subordinated and junior in right of
payment to all Senior Indebtedness as set forth in the Junior Subordinated
Indenture and the Corresponding Junior Subordinated Debentures, but entitled to
receive payment in full of all amounts payable with respect to the Corresponding
Junior Subordinated Debentures, before any Holders of Common Stock or Preferred
Stock of the Corporation receive payments or distributions. Since the
Corporation is the guarantor under each Guarantee and has agreed under the
related Expense Agreement to pay for all costs, expenses and liabilities of each
Issuer Trust (other than such Issuer Trust's obligations to the Holders of its
Trust Securities), the positions of a Holder of the Preferred Securities and a
Holder of such Corresponding Junior Subordinated Debentures relative to other
creditors and to stockholders of the Corporation in the event of liquidation or
bankruptcy of the Corporation are expected to be substantially the same.

     The Certificate and By-laws provide (i) for the classification of the Board
of Directors into three classes to be elected to staggered three-year terms
(with the exception of Mr. David J. Roberts who is elected to a two-year term);
(ii) that special meetings of shareholders may only be called pursuant to a
resolution approved by a majority of the entire Board of Directors and (iii)
subject to the rights of any series of Preferred Stock then outstanding,
directors may be removed from office only for cause and only by the affirmative
vote of the Holders of at least 66 2/3% of the voting power of all of the shares
of the Corporation entitled to vote for the election of directors.
 
     The Board of Directors believes that the provisions described above and the
Rights described under "Description of Capital Stock -- Preferred
Stock -- Preferred Share Purchase Rights" will help assure that all of the
Corporation's shareholders will be treated similarly if certain kinds of
business combinations are effected. However, these provisions also may have the
effect of deterring hostile takeovers or delaying or preventing changes in
control or management of the Corporation, and may make it more difficult to
accomplish certain transactions that are opposed by the incumbent Board of
Directors.
 
NEW YORK BUSINESS CORPORATION LAW
 
     The New York Business Corporation Law (the "BCL") requires the affirmative
vote of at least two thirds of the voting power of the outstanding shares
entitled to vote thereon to approve mergers or consolidations in which the
Corporation would be merged or consolidated or the sale of all or substantially
all the assets of the Corporation. New York law provides that mergers,
consolidations and amendments of the Certificate must also be approved by a
majority of each class of outstanding shares, voting separately as a class, if
the merger, consolidation or amendment would (1) eliminate or limit the voting
rights of the class, (2) subordinate the rights of the class or (3) change such
shares or result in their conversion or in the modification of the terms on
which they may be converted, but only if any such actions would adversely affect
the Holders thereof. Other amendments of the Certificate require the affirmative
vote of a majority of the voting power of the outstanding shares entitled to
vote thereon.

     In addition, Section 912 of the BCL provides, with certain exceptions that
no "domestic corporation" (or any subsidiary) shall engage in a "business
combination" with any "interested shareholder" (generally, a beneficial owner of
20% or more of the outstanding voting stock) for a period of five years of such
shareholder's "stock acquisition date," unless (1) the business combination or
the purchase of stock by the interested shareholder is approved by the board of
directors prior to such shareholder's stock acquisition date, (2) the business
combination is approved by a majority of the voting power of the corporation's
outstanding stock (excluding any stock owned by the interested shareholder) at a
meeting called no earlier than five years after the stock acquisition date or
(3) the consideration paid to shareholders in the business combination (which
may not occur until the expiration of five years from the stock acquisition
date) is at least equal to the highest of certain specified amounts. As defined,
a "domestic corporation" is a corporation incorporated under the BCL or any
other general statute or special act of the State of New York, other than under
the cooperative corporation law; a "business combination" includes a merger or
consolidation, a sale of assets representing 10% or more of the corporation's
consolidated earning power or market value, the issuance of stock amounting to
5% or more of the corporation's outstanding stock and a liquidation proposal
made by the interested shareholder; and the "stock acquisition date" is the date
on which a shareholder first becomes an interested shareholder.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The Corporation has a By-law provision requiring it to indemnify its
directors and officers to the fullest extent permitted in certain circumstances,
to advance expenses, to maintain insurance and to follow certain other
procedures. Provisions of the Certificate eliminate the personal monetary
liability of directors and officers for breaches of duty, except for (i)
breaches of such person's duty of loyalty, (ii) those instances where such
person is found not to have acted in good faith or in knowing violation of law,
(iii) those instances where such person received an improper personal benefit as
the result of such breach and (iv) acts in violation of Section 719 of the BCL.
 
TRANSFER AGENT
 
     The transfer agent for the Common Stock is Mellon Securities Trust Company.
 
                             UNITED STATES TAXATION
 
     Certain special United States federal income tax considerations may be
applicable to the Securities. If any such tax considerations are material to
investors, the applicable Prospectus Supplement will describe such tax
considerations. Prospective purchasers of Securities are urged to consult their
own tax advisors prior to any acquisition of such Securities.
 
                              PLAN OF DISTRIBUTION
 
     The Corporation may sell the Securities directly to purchasers, through
agents, through underwriters, or through dealers.
 
     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, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
     Offers to purchase Securities may be solicited directly by the Corporation
or by agents designated by the Corporation from time to time. Any such agent,
who may be deemed to be an underwriter as that term is defined in the Securities
Act 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
Corporation to such agent will be set forth, in the Prospectus Supplement.
Unless otherwise indicated in the Prospectus Supplement, any such agent will be
acting on a best efforts basis for the period of its appointment. Agents may be
customers of, engage in transactions with or perform services for the
Corporation in the ordinary course of business.
 
                                       35
<PAGE>   75
 
     If an underwriter or underwriters are utilized in the sale, the Corporation
will execute an underwriting agreement with such underwriters at the time of
sale to them, and the names of the underwriters and the terms of the transaction
will be set forth in the Prospectus Supplement, which will be used by the
underwriters to make resales of the Securities in respect of which this
Prospectus is delivered to the public.
 
     If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Corporation will sell such Securities to such
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.
 
     Agents, underwriters and dealers may be entitled under the relevant
agreements to indemnification by the Corporation against certain liabilities,
including liabilities under the Securities Act.
 
     If so indicated in the Prospectus Supplement, the Corporation will
authorize agents or underwriters to solicit offers by certain institutions to
purchase Securities from the Corporation at the public offering price set forth
in the Prospectus Supplement pursuant to delayed delivery contracts
("Contracts") providing for payment and delivery on the date stated in the
Prospectus Supplement. Each Contract will be for an amount not less than, and
unless the Corporation otherwise agrees the aggregate principal amount of
Securities sold pursuant to Contracts shall be not more than, the respective
amounts stated in the Prospectus Supplement. Institutions with which Contracts,
when authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and other institutions, but shall in all cases be subject to the
approval of the Corporation. Contracts will not be subject to any condition
except that the purchase by an institution of the Securities covered by its
Contract shall not at the time of delivery be prohibited under the laws of any
jurisdiction in the United States to which such institution is subject. A
commission indicated in the Prospectus Supplement will be paid to underwriters
or agents soliciting purchases of Securities pursuant to Contracts accepted by
the Corporation.
 
     The place and time of delivery for the Securities in respect of which this
Prospectus is delivered will be set forth in the Prospectus Supplement.
