matters by Cahill Gordon & Reindel, counsel for the Underwriters. It is expected

     Each Preferred Security is convertible on or after                , 1997
(60 days after the date of issue), at the option of the holder thereof into
shares of common stock, par value $.50 per share (the "Common Stock"), of the
Company, at a conversion rate of      shares of Common Stock for each Preferred
Security (equivalent to $       per share of Common Stock), subject to
adjustment in certain circumstances. The Common Stock is quoted on the Nasdaq
National Market (the "NNM") under the symbol "WALB." On December 17, 1996, the
last reported sale price of the Common Stock on the NNM was $18 1/2. Application
will be made to have the Preferred Securities approved for quotation on the NNM,
subject to official notice of issuance, under the symbol "     ". Trading of the
Preferred Securities on the NNM is expected to commence within 30 days after
initial delivery of the Preferred Securities. See "Underwriting."
 
     Holders of the Preferred Securities are entitled to receive cumulative cash
distributions at an annual rate of   % of the liquidation amount of $25 per
Preferred Security, accruing from, and including,               , 1997 and
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year, commencing March 31, 1997 ("distributions"). The payment of
distributions out of moneys held by the Trust and payments on liquidation of the
Trust or the redemption of Preferred Securities, as set forth below, are
guaranteed by the Company (the "Guarantee") to the extent described under
"Description of the Guarantee." The Guarantee covers payments of distributions
and other payments on the Preferred Securities only if and to the extent that
the Company has made a payment of interest or principal or other payments on the
Convertible Debentures held by the Trust as its sole assets. The Guarantee, when
taken together with the Company's obligations under the Convertible Debentures,
the Indenture (as defined herein) pursuant to which the Convertible Debentures
are issued and its obligations under the Declaration, including its obligations
to pay costs, expenses, debts and liabilities of the Trust (other than with
respect to the Trust Securities), provides a full and unconditional guarantee of
amounts due on the Preferred Securities. The obligations of the Company under
the Guarantee rank (i) subordinate and junior in right of payment to all other
liabilities of the Company, (ii) pari passu with the most senior preferred or
preference stock, if any, issued from time to time by the Company and (iii)
senior to the Common Stock. The obligations of the Company under the Convertible
Debentures are subordinate and junior in right of payment to all present and
future Senior Indebtedness (as defined herein) of the Company, which aggregated
approximately $272 million at September 30, 1996, after giving effect to the
application of the net proceeds of the Offering, and rank pari passu with the
Company's other general unsecured obligations. The obligations of the Company
under the Convertible Debentures are also effectively subordinated to all
existing and future indebtedness and other liabilities, including trade
payables, of the Company's subsidiaries. At September 30, 1996, the indebtedness
and other liabilities of such subsidiaries, after giving effect to the
application of the net proceeds of the Offering, aggregated $369 million
(including the $272 million referred to above).
 
     The distribution rate and the distribution payment dates and other payment
dates for the Preferred Securities will correspond to the interest rate and
interest payment dates and other payment dates on the Convertible Debentures,
which will be the sole assets of the Trust. As a result, if principal or
interest is not paid on the Convertible Debentures, no amounts will be paid on
the Preferred Securities because the Trust will not have sufficient funds to
make distributions on the Preferred Securities. In such event, the Guarantee
will not apply to such distributions until the Trust has sufficient funds
available therefor.
 
     The Company has the right to defer payments of interest on the Convertible
Debentures by extending the interest payment period on the Convertible
Debentures at any time for up to 20 consecutive quarters (each, an "Extension
Period"); provided, that no such Extension Period may extend beyond the maturity
date of the Convertible Debentures. If interest payments are so deferred,
distributions on the Preferred Securities will also be deferred. During any
Extension Period, distributions on the Preferred Securities will continue to
accrue with interest thereon (to the extent permitted by applicable law) at an
annual rate of   % per annum compounded quarterly. Additionally, during any
Extension Period, holders of Preferred Securities will be required to include
deferred interest income in the form of original issue discount ("OID") in their
gross income for United States federal income tax purposes in advance of receipt
of cash distributions with respect to such deferred interest payments. See
"Description of the Convertible Debentures -- Interest Income and Option to
Extend Interest Payment Periods," "Risk Factors -- Company Option to Extend
Interest Payment

Periods; OID Risk" and "United States Federal Income Taxation -- Interest Income
and Original Issue Discount."
 
     The Convertible Debentures are redeemable by the Company, in whole or in
part, from time to time, on or after               , 2000, at the redemption
price specified herein, or at any time, in whole or in part, in certain
circumstances upon the occurrence of a Tax Event (as defined herein). If the
Company redeems Convertible Debentures, the Trust will redeem Trust Securities
having an aggregate liquidation amount equal to the aggregate principal amount
of the Convertible Debentures so redeemed at the redemption price specified
herein per Trust Security, plus accrued and unpaid distributions thereon to the
date fixed for redemption. See "Description of the Preferred Securities --
Mandatory Redemption of Trust Securities." The Preferred Securities will be
redeemed upon maturity of the Convertible Debentures on               , 2017. In
addition, upon the occurrence of a Special Event arising from a change in laws
or a change in legal interpretation regarding tax or investment company matters,
unless the Convertible Debentures are redeemed in the limited circumstances
described herein, the Trust shall be dissolved, with the result that the
Convertible Debentures will be distributed to the holders of the Trust
Securities, on a pro rata basis, in lieu of any cash distribution. See
"Description of the Preferred Securities -- Special Event Redemption or
Distribution." In certain circumstances, the Company will have the right to
redeem the Convertible Debentures prior to               , 2000, which would
result in the redemption by the Trust of Trust Securities in the same amount on
a pro rata basis. If the Convertible Debentures are distributed to the holders
of the Preferred Securities, the Company will use its best efforts to have the
Convertible Debentures quoted on the NNM or on such other exchange as the
Preferred Securities are then listed. See "Description of the Preferred
Securities -- Special Event Redemption or Distribution" and "Description of the
Convertible Debentures."
 
     In the event of the involuntary or voluntary dissolution, winding up or
termination of the Trust, after satisfaction of liabilities to creditors of the
Trust as required by applicable law, the holders of the Preferred Securities
will be entitled to receive for each Preferred Security a liquidation amount of
$25 plus accrued and unpaid distributions thereon (including interest thereon)
to the date of payment, unless, in connection with such dissolution, winding up
or termination of the Trust, the Convertible Debentures are distributed to the
holders of the Preferred Securities. See "Description of the Preferred
Securities -- Liquidation Distribution Upon Dissolution."

statements of the Company and the notes thereto appearing elsewhere or

                                  THE COMPANY
 
     The Company is a global leader in the design, development and manufacture
of precision fuel storage and delivery systems and products for automotive and
small engine markets worldwide. The Company manufactures plastic fuel tanks,
fuel pumps, fuel modules, fuel rails and fuel level sensors for sale to
automotive original equipment manufacturers ("OEMs"). Products manufactured for
the small engine market include carburetors and ignitions for chain saws,
outboard marine engines, two-wheeled vehicles, industrial engines and lawn and
garden equipment, such as lawn mowers and weed trimmers. From 1990 to 1995, the
Company (excluding Dyno as defined herein) increased net sales at the compound
rate of approximately 17% per year. This growth was primarily due to the
introduction of new automotive products, penetration of additional automotive
platforms and a recovery in the small engine industry. The Company had net sales
of $459.3 million in 1995 and net sales of $440.5 million for the first nine
months of 1996.
 
WALBRO AUTOMOTIVE
 
     Approximately 75% of the Company's net sales for the first nine months of
1996 were generated by Walbro Automotive. Through Walbro Automotive, the Company
designs, develops and manufactures fuel storage and delivery systems and
components for a broad range of U.S. and foreign manufacturers of passenger
automobiles and light trucks (including minivans). The Company and its joint
ventures hold a strong market position in North America, Europe and South
America and a growing market presence in Asia. In July 1995, the Company
substantially expanded its European automotive business by acquiring the fuel
systems business of Dyno Industrier A.S ("Dyno"), of Oslo, Norway (the "Dyno
Acquisition"). In 1996, management estimates that the Company supplied Chrysler
with approximately three-quarters of its fuel pump and fuel module requirements,
including all requirements for Chrysler's passenger cars and minivans and
approximately one-half of its requirements for Chrysler's light trucks. In
addition, the Company manufactures fuel pumps, fuel modules and fuel rails for a
number of Ford's minivans and light vehicles. Management believes that the
Company manufactures substantially all of the fuel tank systems for Saab and
Volvo light vehicles and all of the fuel tanks for the Mercedes-Benz C Class,
Volkswagen Polo and Renault Twingo. Other automotive customers of the Company,
and its joint ventures, include Audi, Daewoo, Fiat, General Motors, Hyundai,
Kia, Nedcar, Peugeot and Rover. The Company has recently been awarded
significant new contracts that include new fuel tank business for a variety of
General Motors platforms, including Saturn, Monte Carlo/Impala, Sonoma truck,
the Suburban, Yukon/Tahoe and Blazer/Jimmy sport utility vehicles, fuel tanks
for the redesigned Mercedes-Benz C Class, and a complete fuel tank system for
the Dodge Durango sport utility vehicle. In addition, the Company has been
awarded new contracts for the first time with Honda, Toyota and Ssangyong.
 
     The Company's growth strategy is to position itself as a global supplier to
the automotive industry through the design, development and manufacture of
technologically advanced fuel systems and components which are delivered
worldwide. Due to the increasing demand by OEMs for the supply of integrated
automotive systems, Walbro is supplying OEMs with an increasing number of fuel
storage and delivery components with the ultimate goal of being responsible for
the complete fuel storage and delivery systems ("FSDS") which would integrate
all of the components necessary for fuel delivery. By assuming responsibility
for the development of complete systems, the Company allows its OEM customers to
reduce their internal engineering costs, use fewer suppliers and assemble
systems rather than components. Once an OEM designates the Company to supply
FSDS components for a new vehicle program, the OEM usually will continue to
purchase those components from the Company for the life of the program, although
not necessarily for a redesign.
 
                                        6
<PAGE>   8
 
     The Company and its joint ventures in Europe, South America and East Asia
design, develop, manufacture and distribute fuel delivery components and systems
worldwide to support OEMs as they produce vehicles for the global automotive
market. The Company's product development efforts focus on the regulatory and
competitive challenges facing its customers worldwide. For example, the Company
has used its technical skills to develop multi-layer plastic fuel tanks and
onboard running and vapor recovery ("ORVR") devices, which are designed, in
part, to assist OEMs in complying with increasingly strict emission regulations.
 
WALBRO ENGINE MANAGEMENT
 
     Approximately 25% of the Company's net sales for the first nine months of
1996 were generated by Walbro Engine Management. Through Walbro Engine
Management, the Company designs, develops and manufactures diaphragm carburetors
for portable engines (such as those used in chain saws and weed trimmers), float
feed carburetors for ground supported engines (such as those used in lawn mowers
and marine engines) and ignition systems and other components for a variety of
small engine products. The Company believes that it is the world's largest
independent manufacturer of small engine carburetors, with an approximate 75%
share of the global diaphragm carburetor market including sales to such leading
chain saw and weed trimmer manufacturers as Poulan/Weedeater, Deere and Company
(Homelite), Stihl Incorporated, McCulloch Corporation, Ryobi Ltd. and Kioritz
(Echo) Corporation. The Company believes it has an approximate 10% share of the
global float feed carburetor market, including sales to Briggs & Stratton
Corporation, the world's largest small engine manufacturer, Kohler Company,
Tecumseh Products Co., and Mercury Marine, a major manufacturer of outboard
marine engines. The Company produces substantial volumes of float feed
carburetors for the Chinese two-wheeled vehicle market. The Company also
manufactures replacement products for both the automotive and small engine
aftermarkets, sales of which are included within its small engine product
business.
 
     The Company's strategy in the small engine sector is to enhance its
presence as a leading supplier of small engine carburetors, ignition systems and
other small engine products through the development of technologies which assist
customers in complying with new emission standards. The Company's strategy also
includes increasing its global presence, particularly in developing countries
such as The People's Republic of China and India, to profit from the growing
market for carburetors for two-wheeled vehicles, gasoline-powered portable tools
used for infrastructure development and other small engine applications.

                                  THE OFFERING
 
General.......................   The Preferred Securities represent undivided
                                 beneficial interests in the Trust's assets,
                                 which will consist solely of the Convertible
                                 Debentures. The Convertible Debentures, in
                                 which the proceeds of the Preferred Securities
                                 offered hereby will be invested, mature on
                                               , 2017, unless the Convertible
                                 Debentures are redeemed by the Company prior to
                                 such maturity as described under "Description
                                 of the Preferred Securities -- Mandatory
                                 Redemption of Trust Securities" and
                                 "Description of the Preferred Securities --
                                 Special Event Redemption or Distribution."
 
Distributions.................   The distributions payable on each Preferred
                                 Security will be fixed at a rate per annum of
                                   % of the stated liquidation amount of $25 per
                                 Preferred Security, will be cumulative, will
                                 accrue from               , 1997, the date of
                                 issuance of the Preferred Securities, and will
                                 be payable quarterly in arrears, on March 31,
                                 June 30, September 30 and December 31 of each
                                 year, commencing March 31, 1997. See
                                 "Description of the Preferred Securities --
                                 Distributions."
 
Option to Extend Interest
Payment Period................   The Company has the right at any time, and from
                                 time to time, during the term of the
                                 Convertible Debentures, to defer payments of
                                 interest on the Convertible Debentures for a
                                 period not exceeding 20 consecutive quarters;
                                 provided, that no Extension Period may extend
                                 beyond the maturity date of the Convertible
                                 Debentures. As a consequence of the Company's
                                 extension of the interest payment period,
                                 quarterly distributions on the Preferred
                                 Securities would be deferred (though such
                                 distributions would continue to accrue with
                                 interest thereon compounded quarterly, since
                                 interest would continue to accrue on the
                                 Convertible Debentures) during any such
                                 extended interest payment period. In the event
                                 that the Company exercises its right to extend
                                 an interest payment period, then (a) the
                                 Company shall not declare or pay any dividend
                                 on, make any distributions or liquidation
                                 payments with respect to, or redeem, purchase
                                 or acquire any of its capital stock (other than
                                 (i) purchases or acquisitions of shares of
                                 Common Stock in connection with the
                                 satisfaction by the Company of its obligations
                                 under any employee benefit plans or the
                                 satisfaction by the Company of its obligations
                                 pursuant to any contract or security requiring
                                 the Company to purchase shares of the Common
                                 Stock, (ii) as a result of a reclassification
                                 of the Company's capital stock or the exchange
                                 or conversion of one class or series of the
                                 Company's capital stock for another class or
                                 series of the Company's capital stock, (iii)
                                 the purchase of fractional interests in shares
                                 of the Company's capital stock pursuant to the
                                 conversion or exchange provisions of such
                                 capital stock or the security being converted
                                 or exchanged or (iv) stock dividends paid by
                                 the Company where the dividend stock is the
                                 same stock as that on which the dividend is
                                 paid), (b) the Company shall not make any
                                 payment of interest on or principal of (or
                                 premium, if any, on) or repay, repurchase or
                                 redeem any debt securities (including
                                 guarantees) issued by the Company which rank
                                 pari passu with or junior to the Convertible

                                 Debentures and (c) the Company shall not make
                                 any guarantee payments with respect to the
                                 foregoing (other than pursuant to the
                                 Guarantee). Prior to the termination of any
                                 Extension Period, the Company may further
                                 extend such Extension Period, provided that
                                 such Extension Period together with all such
                                 previous and further extensions thereof may not
                                 exceed 20 consecutive quarters. Upon the
                                 termination of any Extension Period and the
                                 payment of all amounts then due, the Company
                                 may commence a new Extension Period, subject to
                                 the foregoing requirements. Should an Extension
                                 Period occur, Preferred Security holders will
                                 continue to recognize interest income for
                                 United States federal income tax purposes. As a
                                 result, such holders will be required to
                                 include such interest in gross income for
                                 United States federal income tax purposes in
                                 advance of the receipt of cash, and such
                                 holders will not receive the cash from the
                                 Trust related to such income if such holders
                                 dispose of Preferred Securities prior to the
                                 record date for payment of distributions. See
                                 "United States Federal Income Taxation --
                                 Interest Income and Original Issue Discount."
 
Conversion into Common
Stock.........................   Each Preferred Security is convertible on or
                                 after                , 1997 (60 days after the
                                 date of issue), at the option of the holder
                                 into shares of Common Stock, at the rate of
                                      shares of Common Stock for each Preferred
                                 Security (equivalent to a conversion price of
                                 $       per share of Common Stock), subject to
                                 adjustment in certain circumstances. The last
                                 reported sale price of the Common Stock on the
                                 NNM on December 17, 1996 was $18 1/2 per share.
                                 In connection with any conversion of a
                                 Preferred Security, the Conversion Agent (as
                                 defined herein) will exchange such Preferred

    recorded a one-time after tax charge of $2,900 for the cumulative effect of
    this accounting change in the year ended December 31, 1993.

    income as an indicator of operating performance or to cash flow as a measure

    understands that it is used by certain investors as one measure of an
    issuer's historical ability to service its debt.

                                  RISK FACTORS
 
     Prospective purchasers of the Preferred Securities offered hereby should
consider carefully the following factors, as well as other information set forth
or incorporated by reference in this Prospectus, in evaluating an investment in
the Preferred Securities.
 
RISK FACTORS RELATING TO THE COMPANY
 
  SUBSTANTIAL LEVERAGE
 
     The Company has consolidated indebtedness that is substantial in relation
to its stockholders' equity.  As of September 30, 1996, the Company had
outstanding approximately $311 million of total debt and approximately $140
million of stockholders' equity.
 
     The Company's indebtedness will have several important consequences for the
holders of the Preferred Securities (or Common Stock which may be acquired upon
conversion), including but not limited to the following: (i) a substantial
portion of the Company's cash flow from operations must be dedicated to debt
service requirements (principal and interest) on its indebtedness and will not
be available for other purposes; (ii) the Company's ability to obtain additional
financing in the future for working capital, capital expenditures, acquisitions,
or for general corporate purposes may be impaired; (iii) the Company's leverage
may increase its vulnerability to economic downturns and limit its ability to
withstand competitive pressures; and (iv) the Company's ability to capitalize on
significant business opportunities may be limited.
 
     The Company's ability to satisfy its debt obligations will depend on its
future operating performance, which will be affected by prevailing economic
conditions and financial, business and other factors, certain of which are
beyond the Company's control. The Company believes, based on current
circumstances, that the Company's cash flow, together with available borrowings
under the Credit Facility (as defined herein) will be sufficient to permit the
Company to meet its operating expenses and to service its debt requirements,
including the Convertible Debentures underlying the Preferred Securities, as
they become due. Significant assumptions underlie this belief, including, among
other things, that the Company will succeed in implementing its business
strategy and there will be no material adverse developments in the business,
liquidity or capital requirements of the Company. If the Company is unable to
service its indebtedness, it will be forced to adopt an alternative strategy
that may include actions such as reducing or delaying capital expenditures,
selling assets, restructuring or refinancing its indebtedness or seeking
additional equity capital. There can be no assurance that any of these
strategies could be effected on satisfactory terms, if at all. In addition,
there can be no assurance that the Company will not increase its leverage to
meet capital requirements in the future. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
  RESTRICTIONS IMPOSED BY TERMS OF INDEBTEDNESS
 
     The indenture relating to the 2005 Notes (the "2005 Note Indenture")
restricts the ability of the Company and its subsidiaries to, among other
things, incur additional indebtedness, pay dividends or make certain other
restricted payments or investments, consummate certain asset sales, enter into
certain transactions with affiliates, incur liens, or merge or consolidate with
any other person or sell, assign, transfer, lease, convey or otherwise dispose
of all or substantially all of their assets. In addition, the Credit Facility
contains other and more restrictive covenants. The agreement under which the
2004 Notes were issued (the "2004 Note Agreement") requires, and the Credit
Facility requires the Company to maintain specified financial ratios and satisfy
certain financial tests. The Company's ability to meet such financial ratios and
tests may be affected by events beyond its control, and there can be no
assurance that the Company will meet such tests. A breach of any of these
covenants could result in an event of default under the 2004 Note Agreement or
the Credit Facility. In an event of default under the 2004 Note Agreement or the
Credit Facility, the lenders thereunder could elect to declare all amounts
borrowed, together with accrued interest, to be immediately due and payable and
the lenders under the Credit Facility could terminate all commitments
thereunder. Such event would constitute an event of default under the 2005 Note
Indenture pursuant to which the 2005 Notes were issued, entitling the holders of
the 2005 Notes to declare the principal and interest on the 2005 Notes to
 
                                       13
<PAGE>   15
 
be immediately due and payable. If any such indebtedness were to be accelerated,
there can be no assurance that the assets of the Company would be sufficient to
repay in full such indebtedness and the other indebtedness of the Company. See
"Description of Certain Indebtedness."
 
  DEPENDENCE ON CUSTOMER RELATIONSHIPS
 
     Sales to Chrysler, the Company's largest customer, accounted for 20%, 19%,
23% and 21% of the Company's consolidated net sales for the nine months ended
September 30, 1996 and the years 1995, 1994 and 1993, respectively. Although the
Company has ongoing supply relationships with Chrysler and certain of its other
OEM customers, there can be no assurance that sales to these customers will
continue at current levels. Further, continuation of the Company's customer
relationships is dependent upon the customers' satisfaction with the price,
quality and delivery of the Company's products. While management believes its
relationships with its customers are mutually satisfactory, if Chrysler or any
of the Company's other significant customers were to reduce substantially or
discontinue its purchases, the Company would be adversely affected. See
"Business -- Walbro Automotive -- Automotive Markets and Customer Base."
 
  CYCLICAL NATURE OF AUTOMOTIVE AND SMALL ENGINE INDUSTRIES
 
     The Company's principal operations are related directly to domestic and
foreign automotive vehicle and small engine consumer product sales. Sales and
production of automobiles and small engine products are cyclical and can be
affected by the strength of a country's general economy, prevailing interest
rates, weather and by other factors which may have an adverse effect on the
level of the Company's sales to automobile and small engine product
manufacturers.
 
  COMPETITION
 
     The automotive fuel system and small engine supply industries in which the
Company operates are highly competitive. There can be no assurance that the
Company's products will continue to compete successfully with the products of
other companies, including the automotive OEMs themselves, many of whom are
significantly larger and have greater financial and other resources available to
them. In addition, the Company is under constant pressure from its major
customers to reduce product costs. Management believes that the Company's
experience in engineering and implementing cost reduction programs and its
ability to develop proprietary new products and to control manufacturing and
development costs should allow the Company's product prices to remain
competitive. However, there can be no assurance that the Company will be able to
improve or maintain its profit margins on sales to vehicle manufacturers and
small engine producers.
 
  RISKS ASSOCIATED WITH FOREIGN OPERATIONS
 
     Walbro has significant international operations, specifically in Europe,
South America and Asia and therefore the Company is subject to various
political, economic and other uncertainties. Among others, the Company's
operations are subject to the risks of taxation policies, foreign exchange
restrictions, changing political conditions and governmental regulations.
Accordingly, no assurance can be given that any of the Company's strategies will
prove to be effective or that management's goals will be achieved. In addition,
the Company receives a substantial portion of its net sales in currencies other
than U.S. Dollars. Fluctuations in the exchange rates of these currencies with
respect to the U.S. Dollar could have an adverse effect on the Company's
financial results. From time to time the Company engages in hedging programs
intended to reduce the Company's exposure to currency fluctuations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Foreign Currency Transactions."
 
  IMPACT OF ENVIRONMENTAL REGULATIONS
 
     In 1992, the California Air Resources Board promulgated comprehensive air
quality regulations limiting small engine emissions, which became effective in
August 1995. A more stringent phase is scheduled to become effective in 1999. In
addition, the Environmental Protection Agency ("EPA") has imposed similar
regulations which became effective in August 1996, with the more stringent phase
expected to become
 
                                       14
<PAGE>   16
 
effective during the 2002 to 2005 period. The implementation of the 1999
California air quality regulations and proposed EPA regulations could
significantly reduce the number of units the Company sells of its current
carburetor models, especially diaphragm carburetors, and the Company's resulting
sales. Hand-held power equipment is most vulnerable to a decrease in demand
because the cost of compliance with these emission standards could force
manufacturers to replace gasoline-powered lawn and garden equipment with
electric-powered equipment. There can be no assurance that the Company will
develop cost effective products to meet all of these regulations or that the
ultimate customer might not select electric-powered equipment instead. See
"Business -- Walbro Engine Management -- Small Engine Industry Overview."
 
  WARRANTY EXPOSURE AND RECALLS
 
     The Company warrants to its OEM customers that its products are free from
defect and that they meet certain OEM designated specifications. The OEMs in
turn offer product warranties to their retail customers. In some instances of
common complaint, the automobile manufacturer will institute a voluntary recall
or will be required by a governmental agency to conduct a recall. As a result,
from time to time, the Company has received claims against it and requests for
payment from its OEM customers to remedy complaints made by the ultimate
consumers. There can be no assurance that the Company will not incur substantial
warranty or recall expense in the future. Such complaints and the related
expenses may have a material adverse effect on the Company's relationship with
its OEM customers, its financial condition and results of operations. See
"Business -- Walbro Automotive -- Automotive Warranty and Other Product
Exposure."
 
RISK FACTORS RELATING TO THE PREFERRED SECURITIES
 
  RANKING OF SUBORDINATE OBLIGATIONS UNDER THE GUARANTEE AND CONVERTIBLE
DEBENTURES
 
     The Company's obligations under the Guarantee are subordinate and junior in
right of payment to all liabilities of the Company and pari passu with the most
senior preferred or preference stock issued, from time to time, if any, by the
Company. The obligations of the Company under the Convertible Debentures are
subordinate and junior in right of payment to all present and future Senior
Indebtedness of the Company and pari passu with obligations to or rights of the
Company's other general unsecured creditors. No payment of principal (including
redemption payments, if any), or premium, if any, or interest on the Convertible
Debentures may be made if (i) any Senior Indebtedness of the Company is not paid
when due and any applicable grace period with respect to such default has ended
with such default not having been cured or waived or ceasing to exist, or (ii)
the maturity of any Senior Indebtedness has been accelerated because of a
default. As of September 30, 1996, Senior Indebtedness, after giving effect to
the application of the net proceeds of the Offering, aggregated approximately
$272 million. In addition, because a significant portion of the Company's
operations are conducted through its subsidiaries and the subsidiaries have not
guaranteed the payment of principal of and interest on the Convertible
Debentures, all liabilities of such subsidiaries, including trade payables, are
effectively senior to the Convertible Debentures and the Guarantee. As of
September 30, 1996, the subsidiaries, after giving effect to the application of
the net proceeds of the Offering, had indebtedness and other liabilities of
approximately $369 million (including the $272 million referred to above)
outstanding. There are no terms in the Preferred Securities, the Convertible
Debentures or the Guarantee that limit the Company's or any subsidiary's ability
to incur additional indebtedness, including indebtedness that ranks senior to
the Convertible Debentures and the Guarantee. See "Description of the Guarantee
- -- Status of the Guarantee" and "Description of the Convertible Debentures."
 
  HOLDING COMPANY STRUCTURE AND SUBORDINATION
 
     The ability of the Trust to pay amounts due on the Preferred Securities is
wholly dependent upon the Company making payments on the Convertible Debentures.
Since the Company is a holding company with a substantial portion of its
operations conducted through its subsidiaries, the ability of the Company to pay
interest and principal on the Convertible Debentures, and, therefore, for the
Trust to make distributions and other payments on the Preferred Securities, will
be dependent on such subsidiaries' ability to pay dividends to the Company.
Because such subsidiaries do not guarantee the payment of principal of and
interest on the Convertible Debentures, claims of holders of the Preferred
Securities effectively will be subordinate to the
 
                                       15
<PAGE>   17
 
claims of creditors of the subsidiaries, including trade creditors. See "--
Ranking of Subordinate Obligations Under the Guarantee and Convertible
Debentures."
 
     The ability of the Company's subsidiaries to pay dividends, as well as to
repay debt, is dependent on the Company's financial and operating performance
which, in turn, is subject to prevailing economic conditions and to financial,
business and other factors beyond its control.
 
  RIGHTS UNDER THE GUARANTEE
 
     The Guarantee will be qualified as an indenture under the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). The Guarantee Trustee (as
defined herein) will act as indenture trustee under the Guarantee for the
purposes of compliance with the provisions of the Trust Indenture Act. The
Guarantee Trustee will hold the Guarantee for the benefit of the holders of the
Preferred Securities.
 
     The Guarantee guarantees to the holders of the Preferred Securities the
payment of (i) any accrued and unpaid distributions that are required to be paid
on the Preferred Securities, to the extent the Trust has funds available
therefor, (ii) the Redemption Price, including all accrued and unpaid
distributions with respect to the Preferred Securities called for redemption by
the Trust, to the extent the Trust has funds available therefor, and (iii) upon
a voluntary or involuntary dissolution, winding-up or termination of the Trust
(other than in connection with the distribution of Convertible Debentures to the
holders of Preferred Securities or a redemption of all the Preferred
Securities), the lesser of (a) the aggregate of the liquidation amount and all
accrued and unpaid distributions on the Preferred Securities to the date of the
payment, to the extent the Trust has funds available therefor, or (b) the amount
of assets of the Trust remaining available for distribution to holders of the
Preferred Securities in liquidation of the Trust. The holders of a majority in
liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee or to direct the exercise of any trust or power conferred
upon the Guarantee Trustee under the Guarantee. Notwithstanding the foregoing,
if the Company has failed to make a payment under the Guarantee, any holder of
Preferred Securities may directly institute a legal proceeding against the
Company to enforce its rights under the Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. If the Company were to default on its obligation to pay amounts payable
on the Convertible Debentures, the Trust would lack available funds for the
payment of distributions or amounts payable on redemption of the Preferred
Securities or otherwise, and, in such event, holders of the Preferred Securities
would not be able to rely upon the Guarantee for payment of such amounts.
Instead, holders of the Preferred Securities would be required to rely on the
enforcement by (i) the Institutional Trustee (as defined herein) of its rights
as registered holder of the Convertible Debentures against the Company pursuant
to the terms of the Convertible Debentures or (ii) such holder of its right
against the Company under certain circumstances to enforce payments on the
Convertible Debentures. See "-- Enforcement of Certain Rights by Holders of
Preferred Securities," "Description of the Guarantee" and "Description of the
Convertible Debentures." The Declaration provides that each holder of Preferred
Securities, by acceptance thereof, agrees to the provisions of the Guarantee,
including the subordination provisions thereof, and the Indenture.
 
  ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
     If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Institutional Trustee of its rights as a holder of the
Convertible Debentures against the Company. In addition, the holders of a
majority in liquidation amount of the Preferred Securities will have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Institutional Trustee or to direct the exercise of any trust or
power conferred upon the Institutional Trustee under the Declaration, including
the right to direct the Institutional Trustee to exercise the remedies available
to it as a holder of the Convertible Debentures. If the Institutional Trustee
fails to enforce its rights under the Convertible Debentures, to the fullest
extent permitted by law, any holder of Preferred Securities may directly
institute a legal proceeding against the Company to enforce the Institutional
Trustee's rights under the Convertible Debentures without first instituting any
legal proceeding against the Institutional Trustee or any other person or
entity. Notwithstanding the foregoing, if a Declaration
 
                                       16
<PAGE>   18
 
Event of Default has occurred and is continuing and such event is attributable
to the failure of the Company to pay interest or principal on the Convertible
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the Convertible Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action") on or after the respective due
date specified in the Convertible Debentures. In connection with such Direct
Action, the Company will be subrogated to the rights of such holder of Preferred
Securities under the Declaration to the extent of any payment made by the
Company to such holder of Preferred Securities in such Direct Action. The
holders of Preferred Securities will not be able to exercise directly any other
remedy available to the holders of the Convertible Debentures. The Indenture
provides that the Indenture Trustee (as defined herein) shall give holders of
the Convertible Debentures notice of all uncured defaults or events of default
within 30 days after occurrence. However, except in the case of a default or an
event of default in payment on the Convertible Debentures, the Indenture Trustee
(as defined herein) is protected in withholding such notice if its officers or
directors in good faith determine that withholding of such notice is in the
interest of the holders.
 
  COMPANY OPTION TO EXTEND INTEREST PAYMENT PERIODS; OID RISK
 
     The Company has the right under the Indenture to defer payments of interest
on the Convertible Debentures by extending the interest payment period at any
time, and from time to time, on the Convertible Debentures. As a consequence of
such an extension, quarterly distributions on the Preferred Securities would be
deferred (but despite such deferral would continue to accrue interest thereon,
compounded quarterly) by the Trust during any such extended interest payment
period. Such right to extend the interest payment period for the Convertible
Debentures is limited to a period not exceeding 20 consecutive quarters, during
which no interest shall be due and payable, provided, that no such Extension
Period may extend beyond the maturity date of the Convertible Debentures. In the
event that the Company exercises this right to defer interest payments, the
Company has agreed, among other things, (a) not to declare or pay dividends on,
or make a distribution with respect to, or redeem or purchase or acquire, or
make a liquidation payment with respect to, any of its capital stock (other than
(i) purchases or acquisitions of shares of Common Stock in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security requiring the Company to purchase shares of Common Stock, (ii) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock or (iii) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged), (b) not to make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees) issued by the Company that rank pari passu with or junior
to the Convertible Debentures and (c) not to make any guarantee payments with
respect to the foregoing (other than pursuant to the Guarantee). Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period; provided, that such Extension Period, together with all
such previous and further extensions thereof, may not exceed 20 consecutive
quarters or extend beyond the maturity date of the Convertible Debenture. Upon
the termination of any Extension Period and the payment of all amounts then due,
the Company may commence a new Extension Period, subject to the above
requirements. See "Description of the Preferred Securities -- Distributions" and
"Description of the Convertible Debentures -- Interest Income and Option to
Extend Interest Payment Periods."
 
     Should the Company exercise its right to defer payments of interest by
extending the interest payment period, each holder of Preferred Securities will
continue to accrue income (as OID) in respect of the deferred interest allocable
to its Preferred Securities for United States federal income tax purposes, which
will be allocated but not distributed, to holders of record of Preferred
Securities. As a result, each such holder of Preferred Securities will recognize
income for United States federal income tax purposes in advance of the receipt
of cash and will not receive the cash from the Trust related to such income if
such holder disposes of its Preferred Securities prior to the record date for
the date on which distributions of such amounts are made. The Company has no
current intention of exercising its right to defer payments of interest by
extending the interest
 
                                       17
<PAGE>   19
 
payment period on the Convertible Debentures. However, should the Company
determine to exercise such right in the future, the market price of the
Preferred Securities is likely to be affected. A holder that disposes of its
Preferred Securities during an Extension Period might not receive the same
return on its investment as a holder that continues to hold its Preferred
Securities. In addition, as a result of the existence of the Company's right to
defer interest payments, the market price of the Preferred Securities (which
represent an undivided beneficial interest in the Convertible Debentures) may be
more volatile than other securities on which OID accrues that do not have such
rights. See "United States Federal Income Taxation -- Interest Income and
Original Issue Discount."
 
  SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
     Upon the occurrence of a Special Event (as defined), the Trust shall be
dissolved, except in the limited circumstance described below, with the result
that the Convertible Debentures would be distributed to the holders of the Trust
Securities in connection with the liquidation of the Trust. In the case of a
Special Event that is a Tax Event, in certain circumstances, the Company shall
have the right to redeem the Convertible Debentures, in whole or in part, in
lieu of a distribution of the Convertible Debentures by the Trust, in which
event the Trust will redeem the Trust Securities on a pro rata basis to the same
extent as the Convertible Debentures are redeemed by the Company. See
"Description of the Preferred Securities -- Special Event Redemption or
Distribution."
 
     Under current United States federal income tax law, a distribution of
Convertible Debentures upon the dissolution of the Trust would not be a taxable
event to holders of the Preferred Securities. Upon occurrence of a Tax Event,
however, a dissolution of the Trust in which holders of the Preferred Securities
receive cash would be a taxable event to such holders. See "United States
Federal Income Taxation -- Receipt of Convertible Debentures or Cash Upon
Liquidation of the Trust."
 
     There can be no assurance as to the market prices for the Preferred
Securities or the Convertible Debentures that may be distributed in exchange for
the Preferred Securities if a dissolution or liquidation of the Trust were to
occur. Accordingly, the Preferred Securities that an investor may purchase,
whether pursuant to the offer made hereby or in the secondary market, or the
Convertible Debentures that a holder of Preferred Securities may receive on
dissolution and liquidation of the Trust, may trade at a discount to the price
that the investor paid to purchase the Preferred Securities offered hereby.
Because holders of Preferred Securities may receive Convertible Debentures upon
the occurrence of a Special Event, prospective purchasers of Preferred
Securities are also making an investment decision with regard to the Convertible
Debentures and should carefully review all the information regarding the
Convertible Debentures contained in this Prospectus. See "Description of the
Preferred Securities -- Special Event Redemption or Distribution."
 
  PROPOSED TAX LEGISLATION
 
     On March 19, 1996, the U.S. Treasury Department proposed certain tax law
changes (the "Proposed Legislation") that would, among other things, generally
deny corporate issuers a deduction for interest in respect of certain debt
obligations, with a maximum term of more than 20 years, that are not shown as
indebtedness on the consolidated balance sheet of the issuer. The Convertible
Debentures have a maximum term of 20 years, and therefore would not be adversely
affected by passage of the Proposed Legislation, even if the Proposed
Legislation has a retroactive effective date. However, there can be no assurance
that any Proposed Legislation, if enacted, would not apply to debt obligations
with a term of 20 or fewer years, including the Convertible Debentures.
 
     On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr.
and House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that the Proposed Legislation,
if adopted by either of the tax-writing committees of Congress, would have an
effective date that is no earlier than the date of "appropriate Congressional
action." Based upon the Joint Statement, it is expected that if the Proposed
Legislation were to be enacted, such legislation would not apply to the
Convertible Debentures because they will be issued prior to the date of any
"appropriate Congressional action." There can be no assurance, however, that any
proposed legislation enacted after the
 
                                       18
<PAGE>   20
 
date hereof will not otherwise adversely affect the ability of the Company to
deduct the interest payable on the Convertible Debentures. Accordingly, there
can be no assurance that a Tax Event will not occur. See "Description of the
Preferred Securities -- Special Event Redemption or Distribution."
 
  LIMITED VOTING RIGHTS
 
     Holders of Preferred Securities will have limited voting rights and will
not be entitled to vote to appoint, remove, replace, or increase or decrease the
number of Trustees, which voting rights are vested exclusively in the holder of
the Common Securities. Prior to any conversion, holders of Preferred Securities
will not have any voting rights with respect to the Common Stock of Walbro. See
"Description of the Preferred Securities -- Voting Rights."
 
  UNCERTAINTY WITH RESPECT TO TRADING PRICE
 
     The Preferred Securities may trade at a price that does not fully reflect
the value of accrued but unpaid interest with respect to the underlying
Convertible Debentures. In addition, as a result of the Company's right to defer
interest payments, the market price of the Preferred Securities (which represent
an undivided interest in the assets of the Trust) may be more volatile than
other similar securities where the issuer does not have such right to defer
interest payments. A holder who disposes of his Preferred Securities between
record dates for payments of distributions thereon will be required to include
accrued but unpaid interest on the Convertible Debentures through the date of
disposition in income as ordinary income (i.e., OID) and to add such amount to
his adjusted tax basis in his pro rata share of the underlying Convertible
Debentures deemed disposed. To the extent the selling price is less than the
holder's adjusted tax basis (which will include, in the form of OID, all accrued
but unpaid interest), a holder will recognize a capital loss. Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for federal income tax purposes. See "United States Federal Income Taxation --
Interest Income and Original Issue Discount" and "-- Sales of Preferred
Securities."

                              WALBRO CAPITAL TRUST
 
     The Trust is a statutory business trust created under Delaware law pursuant
to (i) a declaration of trust, dated as of December 17, 1996, executed by the
Company, as sponsor (the "Sponsor"), and certain of the trustees of the Trust
(as described below) and (ii) the filing of a certificate of trust with the
Secretary of State of the State of Delaware on December 17, 1996. Such
declaration will be amended and restated in its entirety (as so amended and
restated, the "Declaration") substantially in the form filed as an exhibit to
the Registration Statement of which this Prospectus forms a part. The
Declaration will be qualified as an indenture under the Trust Indenture Act.
Upon issuance of the Preferred Securities, the purchasers thereof will own all
of the Preferred Securities. See "Description of the Preferred Securities --
Book-Entry Only Issuance -- The Depository Trust Company." The Company will
directly or indirectly acquire Common Securities in an aggregate liquidation
amount equal to 3% or more of the total capital of the Trust. The Trust exists
for the exclusive purposes of (i) issuing the Trust Securities representing
undivided beneficial interests in the assets of the Trust, (ii) investing the
gross proceeds of the Trust Securities in the Convertible Debentures and (iii)
engaging in only those other activities necessary or incidental thereto.
 
     The Trust's business and affairs are conducted by its trustees, each
appointed by the Company as holder of the Common Securities. Pursuant to the
Declaration, the number of trustees of the Trust will be five: Bankers Trust
Company, as the institutional trustee (the "Institutional Trustee"), Bankers
Trust (Delaware), as the Delaware trustee (the "Delaware Trustee"), and three
individual trustees (the "Regular Trustees" and, together with the Institutional
Trustee and the Delaware Trustee, the "Trustees") will be persons who are
employees or officers of, or who are affiliated with the Company. Initially, the
Regular Trustees will be Lambert E. Althaver, Daniel L. Hittler and Michael A.
Shope, each of whom is an officer of the Company. The Institutional Trustee will
act as the sole indenture trustee under the Declaration for purposes of
compliance with the Trust Indenture Act until removed or replaced by the holder
of the Common Securities. Bankers Trust Company will act as indenture trustee
(the "Guarantee Trustee") under the Guarantee for the purposes of compliance
with the provisions of the Trust Indenture Act. See "Description of the
Guarantee" and "Description of Convertible Debentures."
 
     The Institutional Trustee will hold title to the Convertible Debentures for

     On December 17, 1996, the closing price of the Common Stock as reported on
the NNM was $18 1/2. On December 16, 1996, the Common Stock was held by 1,122
stockholders of record. On December 5, 1996, the Company declared a dividend of
$0.10 per share of Common Stock, payable on January 31, 1997 to stockholders of
record on December 31, 1996. The Company currently intends to continue to
declare and pay cash dividends on its Common Stock on a quarterly basis.
However, all dividend payments are subject to the Company's earnings, financial
condition and capital requirements at the time of declaration and will be paid
only if, as and to the extent declared by the Company's Board of Directors.
 
     The Credit Facility, the 2004 Note Agreement and the 2005 Note Indenture
contain restrictions on the Company's ability to pay dividends. See "Description
of Certain Indebtedness."

                                USE OF PROCEEDS
 
     The proceeds from the sale of the Preferred Securities offered hereby will
be invested by the Trust in the Convertible Debentures. The Company intends to
apply the net proceeds (net of the underwriting commissions and estimated
expenses) from the sale of the Convertible Debentures, estimated to be
approximately $47,937,500 ($55,203,125 if the Underwriters' over-allotment
option is exercised in full) to repay a portion of the borrowings under the
Credit Facility (as defined herein). Borrowings under the Credit Facility bear
interest at a per annum rate equal to LIBOR plus 1.75%. See "Capitalization."
 
     After giving effect to the application of the net proceeds of the Offering,
management believes the availability under the Credit Facility, combined with
funds from operations, will provide the Company with sufficient financial
flexibility to fund planned capital expenditures, most of which are associated
with expansion programs related to contract awards for new automotive OEM
platforms and facilities for new small engine business, and increased working
capital requirements for the foreseeable future. The Company's plans for 1997
capital expenditures, which total approximately $70 million, are principally for
new blow molding machines, tooling and equipment to produce fuel tank systems
for five new platforms the Company has been awarded by U.S. OEM customers and
for facilities to support new small engine business.
 
                                 CAPITALIZATION
 
     The following table sets forth the actual capitalization of the Company as
of September 30, 1996 and as adjusted to give effect to the issuance of the
Preferred Securities being offered hereby, the receipt by the Company of the net
proceeds of approximately $47.9 million therefrom and the application of the
estimated net proceeds as described under "Use of Proceeds." This table should
be read in conjunction with "Selected Financial Information" and the condensed
consolidated financial statements of the Company and related notes thereto
included elsewhere in this Prospectus.

RESULTS OF OPERATIONS
 
     NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 1995
 
     Net Sales. Net sales for the first nine months of 1996 increased 40.8% to
$440.5 million compared to $312.8 million for the same period of 1995. Net sales
for the first nine months of 1995 included two months of Dyno net sales. Net
sales for the first nine months of 1996, excluding net sales relating to Dyno,
increased 1.8%. Net sales of automotive products increased 61.0% to $329.8
million for the first nine months of 1996 compared to $204.8 million for the
same period of 1995 (1.3% increase excluding Dyno net sales). The increased
automotive product net sales were primarily the result of increased net sales
due to the inclusion of Dyno net sales for the entire 1996 period, partially
offset by lower net sales of fuel pumps and fuel modules to one of the Company's
largest customers as a result of the customer's increased in-house production.
 
     Net sales of small engine products increased 2.7% to $88.7 million for the
first nine months of 1996 compared to $86.4 million for the same period of 1995.
The increased small engine product net sales were the result of increased net
sales of ignition systems products and carburetors in China. These increased net
sales were mostly offset by declines in diaphragm carburetors in the U.S. due to
reduced demand for handheld power equipment caused by drought in the Southeast
and Southwest U.S. and cold, wet spring conditions in other areas of the United
States, and in Japan because of lower demand and because of the lower yen-dollar
exchange rate.
 
                                       24
<PAGE>   26
 
     Net sales to the aftermarket decreased 4.7% to $18.3 million for the first
nine months of 1996 compared to $19.2 million for the same period of 1995. Net
sales of aftermarket products declined during the first nine months of 1996
because of increased in-house production by one of the Company's aftermarket
customers.
 
     Cost of Sales. The Company's cost of sales is composed primarily of
material, labor, and manufacturing and engineering overhead. Cost of sales for
the first nine months of 1996 increased 41.4% to $362.0 million compared to
$256.0 million for the same period of 1995 (0.5% increase without Dyno). Cost of
sales as a percent of net sales was 82.2% for the first nine months of 1996
compared to 81.9% for the same period of 1995. For the first nine months of
1996, gross margin decreased slightly primarily as a result of the inclusion of
Dyno, which had a lower margin product mix, partially offset by higher sales
volumes of fuel tanks and fuel rails. In February 1996, the Company announced
its plans to sell the steel fuel rail business at its Ligonier, Indiana plant,
and is currently evaluating its strategic alternatives related to this business.
In small engine products, gross margin decreased primarily because of lower
diaphragm carburetor volume, partially offset by higher volume of ignition
system products.
 
     Selling and Administrative Expenses. Selling and Administrative ("S&A")
expenses (which include research and development ("R&D") expenses) increased by
46.9% for the first nine months of 1996 compared to the same period of 1995. R&D
expenses increased by 29.5% for the first nine months of 1996 compared to the
same period of 1995. As a percent of net sales, S&A expenses increased to 12.0%
for the first nine months of 1996, from 11.5% for the same period in 1995. The
increase in S&A expenses was due primarily to the inclusion of nine months of
Dyno results in 1996 and to start-up costs for the Company's new plastic fuel
tank facility near Sao Paulo, Brazil, its new carburetor facility in Tianjin,
China and its new diecast facility in Tucson, Arizona.
 
     Net Interest Expense. Net interest expense for the first nine months of
1996 increased 121.2% to $14.6 million compared to $6.6 million for the same
period of 1995. This increase was a result of increased borrowings relating to
the Dyno Acquisition and for additional working capital required to support
sales growth and for capital expenditures.
 
     Income Taxes. The provision for income taxes was 34.7% lower for the first
nine months of 1996 compared to the same period of 1995 because of lower taxable
income and a lower effective tax rate of 28.2% for the 1996 nine month period
compared to 35.1% for the same 1995 period. The lower effective tax rate
resulted from research and development tax credits.
 
     Joint Venture Income. The equity in income from joint ventures was $4.0
million for the first nine months of 1996 compared to $2.6 million for the same
period of 1995 because of the increased net sales and improved profitability at
Marwal Systems (France), Marwal do Brasil and Mitsuba-Walbro (Japan) during the
first nine months of 1996, which more than offset the start-up costs at Korea
Automotive Fuel Systems, Ltd.
 
     Net Income and Income Per Share. Net income for the first nine months of
1996 was $11.7 million, an increase of 4.4% compared to net income of $11.2
million for the same period of 1995. The increase was due to the reasons
described above. Net income per share was $1.35 for the first nine months of
1996 compared to $1.30 for the first nine months of 1995.
 
     YEAR ENDED DECEMBER 31, 1995 COMPARED TO 1994, 1994 COMPARED TO 1993
 
     Net Sales. The Company reported record net sales in 1995 of $459.3 million,
an increase of 41.2%. Excluding net sales of $88.5 million contributed by Dyno,
1995 net sales increased 14.0%. Net sales in 1994 were $325.2 million compared
to net sales of $273.5 million in 1993, an increase of 18.9%. The $134.1 million
of additional net sales in 1995 were divided primarily among the automotive
market with a $119.8 million increase and the small engine market with a $10.8
million increase. On a percentage basis, net sales to the automotive market
increased 60.4% in 1995 (15.8% increase without Dyno net sales) compared to an
18.6% increase in 1994, while net sales to the small engine market increased
10.6% in 1995 compared to a 16.5% increase in 1994. Aftermarket net sales were
flat in 1995 compared to an increase of 32.8% in 1994.
 
     Net sales of the Company's original equipment automotive products were
$318.1 million in 1995 ($229.7 million without Dyno), up from $198.3 million in
1994 and $167.2 million in 1993. In 1995, the Company was able to increase U.S.
based automotive product net sales (representing all automotive net sales other
than
 
                                       25
<PAGE>   27
 
those of Dyno) by $31.4 million or 15.8% in spite of the U.S. light vehicle
market decline. The U.S. light vehicle market declined in 1995 to approximately
14.8 million vehicles compared to approximately 15.1 million in 1994, a 2.1%
decrease. U.S. light vehicle sales increased by 8.4% in 1994 and by 8.0% in
1993. The Company was able to record a net sales increase of its U.S. based
automotive products in the face of a declining vehicle market due to increased
net sales of fuel modules (up 23.7%) because of increased use of fuel modules in
the light truck market and increased net sales of fuel modules with higher
dollar content. Light trucks (which include minivans) experienced moderate sales
growth in 1995. The increase in fuel module net sales was partially offset by
the slower than scheduled start-up of a customer's major new vehicle line with
significant fuel module product content.
 
     Net sales of fuel pumps increased by 3.3% and net sales of fuel rails
declined by 14.9% in 1995 compared to 1994 because of the decline in U.S.
passenger car net sales during 1995. Net sales of plastic fuel tanks were $3.0
million in 1995 compared to $0.6 million in 1994, as the Company's U.S. net
sales of plastic fuel tanks did not begin until the fourth quarter of 1994.
Production of plastic fuel tanks increased in the fourth quarter of 1995 for a
second vehicle platform. Net sales of component parts in 1995 were $20.4 million
compared to $3.6 million in 1994. Dyno automotive product net sales were $88.5
million for the last five months of 1995.
 
     In 1994, the Company was able to increase automotive product net sales by
18.6% while the U.S. light vehicle market grew by 8.4%. Automotive product net
sales benefited from the overall market growth, from increased penetration of
existing products and from the development of new products for new models in
1994. In addition, the Company sold its first multi-layer plastic fuel tanks in
1994. For 1994, net sales of fuel pumps increased modestly while net sales of
fuel rails increased by 22.3% and net sales of fuel modules increased by 32.2%.
 
     Net sales of the Company's small engine products also hit a record level of
$112.6 million in 1995, up from $101.8 million in 1994 and $87.4 million in
1993. Overall net sales growth of small engine products was 10.6% in 1995
compared to 16.5% during 1994. Net sales of diaphragm carburetors increased
16.1% in 1995 compared to 7.4% for 1994, from $58.3 million in 1993 to $62.6
million in 1994 to $72.7 million in 1995. Part of the 1995 increase reflects
depressed U.S. diaphragm carburetor sales in the second half of 1994 because of
delays in the emission certification by the California Air Resources Board for
customers' engines during that period. Increases in U.S. sales of diaphragm
carburetors in the first half of 1994 combined with increases in Europe and the
Far East during all of 1994 more than offset the second half decline in the
U.S., resulting in the overall increase of 7.4% for 1994.
 
     Net sales of float feed carburetors decreased 8.7% in 1995 compared to a
27.7% increase for 1994, with $27.4 million of net sales in 1995 versus $30.0
million in 1994 and $23.5 million in 1993. During 1995, float feed carburetor
sales in the U.S. declined as heavy rain in the spring and a drought during the
summer caused lower sales of lawn and garden products and outdoor power
equipment. Also during 1995, the weak market for marine engines contributed to
lower float feed carburetor sales. The significant increase in 1994 float feed
carburetor net sales was primarily due to a 36% increase in net sales to the
Company's largest lawn and garden customer and a 36% increase in net sales of
marine carburetors.
 
     Net sales of small engine ignition systems were $7.9 million in 1995
compared to $7.1 million in 1994 and $5.1 million in 1993 as customer demand has
grown for this expanding family of products. In addition, carburetor net sales
from the Company's subsidiary in China, Fujian Hualong Carburetor, which the
Company acquired in January, 1994, were $4.6 million in 1995 compared to $1.9
million in 1994.
 
     The Company's aftermarket business for both automotive and small engine
products is consolidated as a business unit within Walbro Engine Management, but
reported separately in this discussion. Aftermarket net sales were $25.2 million
in 1995 compared to $25.1 million in 1994. Aftermarket net sales in 1995 were
flat compared to 1994 for two significant reasons. First, the aftermarket
distribution center in Cass City, Michigan was struck by lightning in August,
1995, causing substantial smoke and water damage to the building and its
contents. Aftermarket operations were shut down for three weeks in August as a
result of the fire and subsequent order levels were lower because of the reduced
inventory available to fill orders. Secondly, a major aftermarket
customer/competitor for fuel pumps chose to manufacture more of its
requirements. The 32.8%
 
                                       26
<PAGE>   28
 
increase in 1994 aftermarket net sales was the result of the addition of several
new aftermarket customers and the expansion of the product offering for
aftermarket net sales.
 
     Cost of Sales. Cost of sales was $377.8 million in 1995 ($300.9 million
without Dyno) compared to $261.5 million in 1994 and $216.8 million in 1993.
Cost of sales as a percent of net sales was 82.3% in 1995 (81.1% without Dyno)
compared to 80.4% in 1994 and 79.3% in 1993.
 
     Gross margin for U.S. based automotive products decreased in 1995 because
of lower volumes of fuel rails partially offset by higher volumes of fuel
modules and plastic fuel tanks. The Company's Ligonier, Indiana plant, which
makes steel fuel rails, experienced significantly higher costs in the second
half of 1995 because of lower volumes related to lower passenger car sales. Cost
of sales as a percent of net sales at Dyno was 86.9% for the last five months of
1995. The Dyno gross margin was lower than anticipated during the last five
months of 1995 because of higher raw material prices and lower volumes due to
seasonally lower production schedules and because of a weaker European
automotive market during this period. Also contributing to the higher cost of
sales as a percent of net sales were continuing start-up costs at the Company's
Ossian, Indiana plastic fuel tank plant. The 1994 cost of sales as a percent of
net sales increased because of the Ossian plant start-up costs and additional
costs of expanding production capacity for fuel modules at the Company's
Meriden, Connecticut plant.
 
     Cost of sales as a percent of net sales for small engine products increased
for 1995 because of lower volume of float feed carburetors in the U.S., lower
production volumes at the Company's Singapore manufacturing facility and the
stronger Singapore Dollar versus the U.S. Dollar. These increased costs were
partially offset by higher volume of diaphragm carburetors in Japan and Mexico
and higher volume of float feed carburetors in China. Gross margin decreased in
1994 primarily because of lower volume of diaphragm carburetors in the U.S.
during the second half of the year. A secondary factor for the decreased gross
margin was the higher cost of manufacturing carburetors in Japan and Singapore
as a result of the weaker U.S. Dollar during 1994.
 
     In December 1990, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 106 (SFAS 106), Employer's Accounting for
Post Retirement Benefits Other Than Pensions, and the Company changed its method
of accounting for these benefits in 1993 as required by SFAS 106. See Note 12 of
the Notes to the Consolidated Financial Statements for a detailed discussion of
the impact of this change.
 
     Selling and Administrative Expenses. S&A expenses were $57.5 million in
1995, an increase of 46.3% (25.6% without Dyno) compared to $39.3 million in
1994. The 1994 S&A expenses increased by 19.0% compared to $33.0 million in
1993. As a percent of net sales, S&A expenses were 12.5% in 1995 (13.3% without
Dyno), 12.1% in 1994 and 12.1% in 1993. In 1995, S&A expenses increased because
of increased spending for research and development, expansion of the Company's
automotive systems center in Auburn Hills, Michigan and its automotive testing
center in Caro, Michigan, the inclusion of five months of Dyno results in 1995
and general expenses related to adding manufacturing capacity in Meriden,
Connecticut. In 1994, most S&A expense categories increased to support the net
sales growth. Research and development spending increased by 37.3% (14.4%
without Dyno) in 1995 and by 28.3% in 1994 to support the new product
development efforts required by emission regulations for both automotive and
small engine products. Incentive compensation expense in the small engine
business increased in 1994 and again in 1995 because of higher profitability.
 
     Reorganization Charges. In 1993, the Company recorded a $1.8 million
reorganization charge reflecting the Company's actual and anticipated expenses
from reorganization of the executive management team at Walbro Automotive. In
1993, $1.0 million was paid and the remaining $0.8 million was paid in 1994. See
Note 7 of the Notes to the Consolidated Financial Statements.
 
     Loss on Foreign Exchange Transactions. Foreign exchange contracts are used
primarily to manage the exposure to foreign currency losses from operations in
foreign countries, from investments in foreign joint ventures and from
commitments in foreign currencies. In 1992, the Company entered into forward
foreign exchange contracts to hedge the Company's foreign currency exposure
related to a sales commitment to a foreign customer. The loss on these contracts
was treated as a hedge for accounting purposes and recorded as a deferred asset,
which is being amortized as foreign currency exchange loss. In 1993 and 1994,
the Company
 
                                       27
<PAGE>   29
 
entered into foreign exchange contracts to hedge the Company's foreign currency
risk from foreign currency commitments which did not qualify for deferred
accounting treatment and the losses were recorded as foreign currency exchange
loss in 1993 and 1994. The foreign currency exchange loss in 1995, 1994 and 1993
was $1.5 million, $2.6 million and $1.5 million, respectively. See Note 14 of
the Notes to the Consolidated Financial Statements.
 
     Net Interest Expense. Net interest expense was $11.1 million in 1995, $3.8
million in 1994 and $2.6 million in 1993. To finance the Dyno Acquisition in
July 1995, the Company sold $110 million in aggregate principal amount of the
2005 Notes (as defined herein) and obtained a $135 million secured Credit
Facility (as defined herein). Borrowing levels were also higher in 1995 to
support the higher level of capital expenditures for facility expansions.
General interest rates declined during 1995 but the additional borrowings and
the shift to a higher percentage of long-term fixed rate debt raised the average
cost of capital and caused the higher interest expense. The 1994 increased
interest expense resulted from higher interest rates, increased borrowings for
additional working capital and the full year effect of financing the Company's
Ossian, Indiana plant. During October of 1994, the Company sold $45 million of
the 2004 Notes (as defined herein) which contributed to the higher net interest
expense. The average cost of borrowing was 7.4% in 1995, 5.9% in 1994 and 4.9%
in 1993. See Note 8 of the Notes to Consolidated Financial Statements for
details of the borrowings.
 
     Income Taxes. The provision for income taxes was lower for 1995 compared to
1994 because of an R&D tax credit recorded in 1995. This tax credit resulted
from a change by the Internal Revenue Service in defining the R&D activities
which qualify for the tax credit. The $3.0 million credit results from R&D
activities at the Company from 1988 through 1995. The R&D tax credit resulted in
an effective tax rate of 10.8% for 1995 compared to 32.5% for 1994.
 
     Joint Venture Income. The Company's equity in income of joint ventures was
$3.9 million in 1995, $2.6 million in 1994 and a loss of $89,000 in 1993. The
loss in 1993 was due primarily to first year losses of $538,000 in Brazil and
the significant income in 1994 and 1995 resulted from increased net sales and
profits in all the Company's joint ventures.
 
     Net Income and Income Per Share. Net income for 1995 was $13.8 million, a
decrease of 5.5% compared to $14.6 million in 1994. Income before cumulative
effect of accounting change was $12.6 million in 1993 with net income of $9.7
million for the same period. Net income per share was $1.61 for 1995 compared
with $1.70 for 1994. Income per share before cumulative effect of accounting
change was $1.47 with net income per share of $1.13 for 1993. Net income as a
percent of net sales was 3.0% in 1995, 4.5% in 1994 and 4.6% in 1993 (income
before accounting change as a percent of net sales). The decline in net income
as a percent of net sales in 1995 was related to the Dyno Acquisition, which
contributed to lower profit margins in 1995 and resulted in increased interest
expense. The decline in net income as a percent of net sales during 1994 was the
result of higher cost of sales, higher interest expense and foreign exchange
losses as explained above.
 
INFLATION
 
     Inflation potentially affects the Company in two principal ways. First, a
portion of the Company's debt is tied to prevailing short-term interest rates
which may change as a result of inflation rates, translating into changes in
interest expense. Second, general inflation can impact material purchases, labor
and other costs. In many cases, the Company has limited ability to pass through
inflation-related cost increases due to the competitive nature of the markets
that the Company serves. In the past three years, however, inflation has not
been a significant factor for the Company.
 
FOREIGN CURRENCY TRANSACTIONS
 
     Approximately 51% of the Company's net sales during the first nine months
of 1996 were derived from manufacturing operations in Europe, Asia and Mexico.
The financial position and the results of operations of the Company's
subsidiaries in Europe (36% of net sales), Japan (4% of net sales) and China (1%
of net sales) are measured in the local currency of the countries in which they
operate and translated into U.S. dollars. The effects of foreign currency
fluctuations in Europe, Japan and China are somewhat mitigated by the fact that
expenses are generally incurred in the same currencies in which net sales are
generated and the reported
 
                                       28
<PAGE>   30
 
income of these subsidiaries will be higher or lower depending on a weakening or
strengthening of the U.S. dollar.
 
     For the Company's subsidiary in Singapore (3% of net sales) the expenses
are generally incurred in the local currency, but net sales are generated in
U.S. dollars; therefore, results of operations are more directly influenced by a
weakening or strengthening of the local currency. The Company's subsidiary in
Mexico (7% of net sales) operates as a maquiladora, or contract manufacturer,
where certain direct manufacturing expenses are incurred in the local currency
and net sales are generated in U.S. dollars. Thus, results of operations of the
Company's subsidiary in Mexico are also more directly influenced by a weakening
or strengthening of the local currency.
 
     Approximately 46% of the Company's assets at September 30, 1996 are based
in its foreign operations and are translated into U.S. dollars at foreign
currency exchange rates in effect as of the end of each period. Accordingly, the
Company's consolidated stockholders' equity will fluctuate depending upon the
weakening or strengthening of the U.S. dollar. In addition, the Company has
equity investments in unconsolidated joint ventures in France, Brazil, Japan,
Korea and Mexico. The Company's reported income from these joint ventures will
be higher or lower depending upon a weakening or strengthening of the U.S.
dollar.
 
     The Company's strategy for management of currency risk relies primarily
upon the use of forward currency exchange contracts to manage its exposure to
foreign currency fluctuations related to its operations in foreign countries, to
manage certain of its firm transaction commitments in foreign currencies and to
hedge its equity investment in certain foreign joint ventures.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As of September 30, 1996, the Company had outstanding $15.4 million in
short-term debt, including current portion of long-term debt, and $295.5 million
in long-term debt. The approximate minimum principal payments required on the
Company's long-term debt in each of the five fiscal years subsequent to December
31, 1995 are $1.1 million in 1996, $1.3 million in 1997, $7.9 million in 1998,
$7.6 million in 1999, $64.6 million in 2000 and $152.0 million thereafter.
 
     The net purchase price of the Dyno Acquisition was approximately $114
million (approximately $130 million less approximately $16 million cash acquired
by the Company). The Company financed the acquisition through the combination of
an issuance of $110 million in aggregate principal amount of its 2005 Notes (as
defined herein) and a $135 million secured Credit Facility (as defined herein)
with a group of commercial banks. At September 30, 1996, the Company had
available to it approximately $9 million under the Credit Facility.
 
     In the first nine months of 1996, net working capital increased by $10.0
million and cash used for investing activities was $70.4 million. Financing
activities provided $66.5 million with the remaining cash generated from
operations. In the first nine months of 1995, net working capital increased by
$3.9 million, net of acquisition, while cash used for investing activities was
$169.8 million. Financing activities provided $168.6 million with the remaining
cash generated from operations.
 
     As of September 30, 1996, accounts receivable amounted to $140.8 million,
an increase of $9.9 million, compared to $130.9 million at September 30, 1995.
The increase was due to longer collection periods due to revised payment terms
with certain customers. The average collection period at September 30, 1996 was
89.2 days compared to the average collection period at September 30, 1995 of
77.8 days.
 
     The Company's plans for 1996 capital expenditures total approximately $80
million, of which $70 million had been spent in the first nine months of 1996.
The major projects for 1996 included new blow molding machines for plastic fuel
tanks, expansion of the Ossian, Indiana plant and new plants in Meriden,
Connecticut, Belgium and Brazil. The Company's plans for 1997 capital
expenditures, which total approximately $70 million, are principally for new
blow molding machines, tooling and equipment to produce fuel tank systems for
five new platforms the Company has been awarded by U.S. OEM customers and for
facilities to support new small engine business.
 
     Management believes that the Company's long-term cash needs will continue
to be provided principally by operating activities supplemented, to the extent
required, by borrowing under the Company's existing and future credit
facilities. Management expects to replace these credit facilities as they expire
with comparable facilities. Management believes the availability under the
Credit Facility, combined with funds from operations, will provide the Company
with sufficient financial flexibility to fund planned capital expenditures and
increased working capital requirements for the foreseeable future.

WALBRO AUTOMOTIVE
 
  AUTOMOTIVE INDUSTRY OVERVIEW
 
     A number of trends within the global automotive market have had and will
continue to have a fundamental impact on the Company's future profitability and
growth prospects, including: the shift by OEMs to the purchase of "systems"
rather than individual components, the globalization of the OEM supplier base,
the expansion of OEM supplier responsibilities and increased emissions
regulation. These trends have contributed to a consolidation of OEM suppliers
which the Company expects will continue.
 
     Purchase of Integrated Systems. Automotive OEMs are relying increasingly on
suppliers who can provide entire systems rather than a number of different
parts. OEMs can reduce their own internal engineering efforts and the number of
suppliers by purchasing systems rather than components. Management believes the
engineering and technological challenges facing systems suppliers will continue
to grow as these systems become more complex. To strengthen the Company's
position as a major supplier of automotive fuel systems, the Company is
investing in its engineering and testing capabilities and actively pursuing its
systems philosophy. The Company believes that the systems approach is being
adopted outside North America and that the Company will be able to provide
systems to the European market in the future.
 
     Globalization of the OEM Supplier Base. Several OEMs, including Ford,
General Motors and Volkswagen, are introducing automobile models which are
designed for the world automotive market ("World Cars"). This departure from the
historical practice of designing separate models for each regional market is
requiring suppliers to establish international development and manufacturing
facilities capable of providing system components with consistent quality on a
worldwide basis. The Company believes it is well positioned as a major supplier
of fuel storage and delivery systems ("FSDS") to the world automotive markets.
 
     Expansion of OEM Supplier Responsibilities. Since the 1980s, Ford, Chrysler
and General Motors have been actively reducing their respective supplier bases
to those who accept significant responsibility for product management and meet
increasingly strict standards for product quality, on time delivery and
manufacturing costs. These suppliers are expected to control all aspects of
production of system components, including design, development, component
sourcing, manufacturing, quality assurance, testing and delivery to the
customer's assembly plant. The Company believes that many suppliers do not have
the resources to meet these OEM requirements and that the automotive OEM
supplier market will be divided among a smaller group of key suppliers. The
Company has received a number of quality awards from its OEM customers,
including the Ford Q1 Award, Chrysler QE Award and General Motors Supplier of
the Year Award, and believes that this supplier consolidation provides an
opportunity for the Company's increased penetration of the OEM market.
 
     Increasing Emissions Regulation. Beginning in the late 1970s, U.S.
environmental regulations, including fuel economy regulations and the Clean Air
Act and its Amendments, have had a significant impact on fuel systems and the
controls placed on mobile source emissions. As a result, U.S. automotive fuel
systems have evolved from mechanically controlled carbureted systems to more
sophisticated, electronically controlled fuel injection systems. Governmental
action in many other parts of the world is forcing a similar transition to
engine management systems which produce less emissions. For example, the
European Economic Community, which previously had less stringent automotive
exhaust regulations, adopted exhaust standards effective January 1, 1993 which
are comparable to 1983 U.S. requirements.
 
     Compliance with these regulations has resulted in efforts to reduce
evaporative emissions and the development of new "flexible" fuels such as
ethanol and methanol blends. In response to these changes, the Company has
developed a number of products including electric pumps designed for electronic
fuel injection systems, onboard running and vapor recovery ("ORVR") systems and
plastic fuel tanks which reduce hydrocarbon permeation and are corrosion
resistant to flexible fuels.

  AUTOMOTIVE BUSINESS STRATEGY
 
     The Company intends to capitalize on trends in the automotive industry
through the development of its fuel systems technology and expansion of its
product line and customer base. The key elements of the Company's strategy
include:
 
     Systems Approach to Product Development. The Company is utilizing its
expertise to develop integrated FSDS which reduce evaporative emissions, are
compatible with the corrosive nature of flexible fuels and provide customers
with the cost savings and convenience of purchasing complete systems rather than
numerous individual components. The Company's "systems" approach to product
development is designed to allow the Company to increase product content on each
vehicle in which its products are installed while providing customers with
substantial performance and cost benefits. This systems approach has made
possible an increase in the dollar value of the Company's products per vehicle.
For example, the new Dodge Durango V-8, which is scheduled to begin volume
production in the third quarter of 1997, is equipped with the Company's fuel
storage and delivery system and a plastic fuel rail. These products have a
selling price of approximately $130 to $160 compared to a typical 1987 Chrysler
vehicle equipped with only $15 of the Company's products. The Company's ability
to assume responsibility for the development of FSDS allows OEMs to reduce
internal engineering efforts and use fewer suppliers through the purchase of
systems rather than components.
 
     Global Capabilities. The Company's international manufacturing and market
presence allows the Company to offer its current and future FSDS technology to
the global automotive market. The Company's presence in Europe provides it with
additional resources and marketing contacts to supply integrated fuel systems to
both European and North American OEMs assembling vehicles in Europe and European
OEMs assembling vehicles in the United States. The Company's international sales
for the first nine months of 1996 were 51% of the Company's net sales (excluding
joint ventures) compared to 20% in 1994. The Company's plastic tank
manufacturing capability allows it to pursue its systems strategy in Europe and
serve OEM customers as they confront new environmental and regulatory challenges
worldwide and introduce World Cars designed for sale to the global automotive
market. In addition, the Company has a market presence in Brazil, South Korea
and Japan and it has entered into joint ventures with foreign manufacturers in
Brazil, France, India, Japan, Mexico, Argentina and South Korea which enable the
Company to access those foreign markets.
 
     Technical and Product Development Capabilities. The Company's engineers
focus their research and development efforts to respond to the technical
challenges facing their customers. The Company has designed its current line of
FSDS products in response to U.S. fuel economy and emission regulations and
changing consumer demands over the past two decades. Management believes that
the Company is well positioned to capitalize on the emergence of more stringent
global emission regulations through the development of a new generation of
products and systems with greater fuel efficiency, reduced component weight,
improved durability, fuel vapor control and flexible fuel compatibility. An
example of these products is the ORVR system which captures fuel vapors from the
fuel system and routes them to a carbon canister for storage and reuse.
 
     The Company has made substantial investments in fuel systems technology,
product design and test capability and technical personnel to advance FSDS
technology and respond to customer needs. The Company's new state-of-the-art
systems center in Auburn Hills, Michigan provides the Company with the
full-service product management capability which OEMs require of key suppliers
and provides the Company with a competitive advantage in the development of
proprietary fuel systems technology. Similarly, the Company intends to build a
new systems center in Europe to provide product design and test capabilities and
has longer term plans to expand its technical capabilities in Asia.
 
  AUTOMOTIVE PRODUCTS
 
     The Company's product development engineers design fuel storage and
delivery systems in response to customer needs and in anticipation of evolving
trends in the market. Today's electronic fuel injected engines demand an
uninterrupted supply of fuel under pressure and some vehicles require complex
fuel tank
 
                                       32

configurations. The Company specializes in technology employed in the FSDS and
currently manufactures and sells fuel pumps, fuel modules, fuel level sensors,
plastic fuel tanks, bracket assemblies and fuel rails.
 
     In response to the environmental and fuel efficiency demands on today's
automobiles, the Company has developed, and is continually taking steps to
improve, an electric pump designed to deliver fuel under pressure to electronic
fuel injection equipped engines. The pump is fastened to a bracket and flange
assembly, which allows the pump to be mounted in the fuel tank. The assembly has
been increasingly replaced with a single integrated unit, called a fuel module,
which performs all of the functions of the assembly described above. The fuel
module is a complete, value-added package for specific applications composed of
a fuel pump, plastic reservoir, fuel level sensor and related parts. These
injection-molded plastic units fit inside the fuel tank, ensuring continuous
fuel delivery under low fuel conditions, maximum vehicle driving range and
enhanced fuel delivery under high temperature conditions, all at a reduced noise
level. Although vehicles were not equipped with fuel modules until 1988,
approximately 28% of cars and light trucks currently sold by General Motors,
Ford and Chrysler in North America in 1995 use fuel modules. In 1995, the
Company supplied approximately 70% of all of the fuel modules purchased in North
America, principally to Ford and Chrysler.
 
     Approximately 25% of North American vehicles and 70% of European vehicles
produced in 1995 contained plastic fuel tanks. Plastic fuel tanks offer several
advantages over conventional steel tanks, including lighter weight, greater
corrosion resistance to new, cleaner-burning fuels like methanol and the ability
to be produced in unusual shapes to better use available space. In anticipation
of customer demand in North America for more sophisticated fuel tanks, the
Company built a new facility in Ossian, Indiana in 1993 to produce plastic
multi-layer fuel tanks. The Company began production of three-layer plastic fuel
tanks during the fourth quarter of 1994 for the 1995 Ford Windstar. The
multi-layer construction of the Company's new, six-layer plastic tank
substantially eliminates fuel permeation, making this one of the first plastic
tanks which complies with the U.S. Environmental Protection Agency (the "EPA")
permeability requirements which became effective beginning in model year 1996.
The first production run of six-layer tanks began in 1996 for the GM T600.
 
     The Company is currently producing mono-layer plastic fuel tanks, which
include coatings and permeation barriers that meet European emission
requirements, for Audi, Mercedes-Benz, Nedcar, Peugeot, Renault, Rover, Saab,
Volkswagen and Volvo. As these customers require more sophisticated fuel tanks,
the Company will likely supplement a portion of its mono-layer blow molding
machines with multi-layer blow molding machines to provide the Company's OEM
customers in Europe with advanced, plastic fuel tank technology.
 
     The Company also produces metal and plastic fuel rails suitable for a
variety of engine applications. An extension of the FSDS concept, these
under-hood components, located on the engine, deliver fuel to the individual
fuel injectors used in electronic multi-point fuel injection systems. The
Company has designed a plastic fuel rail which is superior to metal fuel rails
in cost, weight and handling of more corrosive flexible fuels. In 1994, Ford
began to install this new rail on the three-liter engine in the Windstar. In
1996, Chrysler began to install this rail on the V-8 engine for its Dodge Ram
and Dakota trucks.
 
     An important advantage of the Company's systems approach is that it assists
customers in responding to developments in safety and environmental standards.
For example, current environmental regulations call for a FSDS that minimizes or
eliminates the escape of fuel vapors during refueling, storage and operation. In
January 1994, the EPA announced regulations governing ORVR systems as mandated
by the 1990 Clean Air Act. The regulations require installation of devices which
trap hydrocarbon vapors on a phase-in basis for passenger cars beginning in
model year 1998 and for light trucks in model year 2001. In anticipation of
these regulations, the Company has developed a variety of ORVR devices which
help prevent fuel vapor loss from fuel delivery systems. These devices are
expected to enter production during 1997.
 
  AUTOMOTIVE MARKETS AND CUSTOMER BASE
 
     The Company currently provides a wide variety of products to a diverse
customer base in a number of geographic areas. The Company has recently been
awarded significant new contracts that include new fuel tank business for a
variety of General Motors platforms, including Saturn, Monte Carlo/Impala,
Sonoma

(1) South American customers supplied by Marwal do Brasil, Ltda.
 
(2) European customers supplied by Marwal Systems, S.N.C.
 
(3) Korean customers supplied through Korean Automotive Fuel Systems, Ltd.
 
     In addition to the customers described above, the Company also supplies a
variety of its products to a number of other customers including, but not
limited to, the following: IBC, Iveco, J.I. Case, Lister Petter, New Holland,
Scandia, VME and Steyr-Puch.
 
     North America. Net sales to Chrysler and Ford for the first nine months of
1996 accounted for 20% and 11% of the Company's consolidated net sales,
respectively. Both of these customers have ongoing supply relationships with the
Company which are subject to continued satisfactory price, quality and delivery.
The Company is the primary outside supplier of fuel pumps, the core of the FSDS,
to Chrysler and Ford. In the past, the Company has capitalized on its fuel
system components penetration to supply additional fuel system products, such as
fuel modules and fuel rails, to Chrysler and Ford, and to assume a key role in
the development of new fuel system products, such as ORVR devices. General
Motors historically developed and produced substantially all of its fuel storage
and delivery systems internally but recently has sourced a significant portion
of future plastic fuel tank programs to outside suppliers, including the
Company.
 
     In October 1996, the Company announced its intent to form a joint venture
with two minority business owners to produce automotive components in Detroit's
Empowerment Zone. The joint venture is expected to manufacture FSDS products
(including blow-molded plastic fuel tanks), air ducts, reservoirs and similar
small blow-molded components for automotive applications. General Motors has
awarded $300 million of new business to the proposed joint venture over a
five-year period commencing in 1998. Chrysler has also committed to awarding new
business to the proposed joint venture. In September 1996, the Company received
a tax credit worth an estimated $13.6 million from the Michigan Economic Growth
Authority for this new facility.
 
     Europe. In 1991, the Company began operations in Europe with the
establishment of its Marwal Systems joint venture in France with Magneti Marelli
S.p.A. of Italy to serve customers that include Fiat, Nissan, Peugeot, Renault,
Rover, Saab and Volvo. As a result of the Dyno Acquisition, the Company is the
only integrated FSDS supplier in Europe, which has provided the Company with the
immediate opportunity to increase its participation in the European automotive
market. In addition, the Company is using its
 
                                       35
<PAGE>   37
 
relationships in the U.S. to increase its sales to North American manufacturers
in Europe. Similarly, the Company is leveraging its relationships with
Mercedes-Benz, Peugeot, Renault, Saab, Volkswagen, Volvo and other European
manufacturers to enhance the Company's marketing efforts with these European
manufacturers around the world. Approximately 70% of the European light duty
vehicles and 25% of the North American light duty vehicles are equipped with
plastic fuel tanks. The Company's management estimates that operations in Europe
produced plastic fuel tanks accounting for approximately 20% of the European
plastic fuel tank market in the first nine months of 1996.
 
     South America. In January 1993, operations began at the Company's Marwal do
Brasil joint venture, which targets the South American automotive market of
approximately two million units per year. In September 1995, the Company
established Walbro Automotive do Brasil to manufacture plastic fuel tanks for
the Brazilian automotive market. It began production of plastic fuel tanks for
Volkswagen in November 1996. The Company recently received an order from Ford
for a supply of plastic fuel tanks for Ranger trucks to be produced in
Argentina.
 
     Asia. In December 1986, the Company entered into a joint venture in Japan
known as Mitsuba-Walbro, Inc. with Mitsuba Electric Manufacturing Company to
manufacture fuel pump components. In November 1994, the Company established
Korea Automotive Fuel Systems Ltd., a joint venture with Daewoo Precision
Industries Ltd. in South Korea, to manufacture and market fuel sending units
(which include a fuel pump, bracket and level sensor) for the domestic Korean
automotive market (estimated at approximately 1.5 million units per year) and
additional export markets established by Korean OEMs. In November 1995, the
Company established Mutual Walbro P. Ltd., a joint venture with Mutual
Industries Ltd., in India to manufacture plastic fuel tanks for the Indian
automotive market.
 
  AUTOMOTIVE COMPETITION
 
     The Company competes with several other manufacturers, including the OEMs
themselves, many of which have greater sales and financial resources than the
Company. In the fuel pump market, the Company's major competitors include Robert
Bosch GmbH, Denso Corp., Ltd., VDO (a division of Mannesmann), Electronics and
Fuel Handling Division of Ford and Delphi Automotive Systems (GM's component
group). In the fuel rail market, the Company's major competitors include Delphi,
Ford, Echlin Inc. and Siemens A.G. The Company has competition in the fuel
module market from Delphi and Ford. The Company's largest competitors in the
plastic fuel tank market include Kautex Werke Reinold Hagen A.G. (which signed a
definitive agreement in November 1996 to be acquired by Textron Inc., subject to
regulatory approval), Solvay S.A., Plastic Omnium Industries, Inc. and Ford.
Steel tanks, manufactured primarily by the OEMs, also compete with the Company's
plastic fuel tanks.
 
     The Company competes for new business both at the beginning of the
development of new models and upon the redesign of existing models. New model
development generally begins two to three years prior to a product introduction.
Once a producer has been designated to supply parts for a new program, an OEM
usually will continue to purchase those parts from the designated producer for
the life of the program, although not necessarily for a redesign. Competitive
factors in the market for fuel storage and delivery products include product
quality and reliability, cost and timely delivery, technical expertise and
development capability and new product innovation.
 
  AUTOMOTIVE SALES AND ENGINEERING SUPPORT
 
     Sales of the Company's FSDS products to automotive OEMs are made directly
by the Company's sales/engineering force, who not only sell the products but
assist customers with related engineering matters. Because of the automobile
design process, the Company is generally able to determine a few years in
advance the models for which it will supply products. The Company's sales force
works closely with the Company's engineering departments and systems center in
Auburn Hills in the research, design, development and improvement of its
products. When the Company's systems center in Europe is completed, the Company
and Marwal will also have additional design and research capabilities to provide
OEMs in Europe with full-service product management. Because the Company has the
capability to provide comprehensive engineering
 
                                       36
<PAGE>   38
 
resources with respect to its product line and assume increasing responsibility
for the development of FSDS products, the Company has been successful in
responding to the decisions by OEMs to consolidate suppliers and reduce internal
engineering resources.
 
  AUTOMOTIVE WARRANTY AND OTHER PRODUCT EXPOSURE
 
     The design and manufacture of fuel systems entails an inherent risk that a
governmental authority or a customer may require the recall of one of the
Company's products or a product in which one of the Company's products has been
installed. The Company has taken and intends to continue to take all reasonable
precautions to avoid the risk of exposure to an expensive recall campaign which
could have a material adverse effect on the business and financial condition of
the Company.
 
WALBRO ENGINE MANAGEMENT
 
  SMALL ENGINE INDUSTRY OVERVIEW
 
     The small engine industry is facing a number of environmentally driven
changes which will require an increased emphasis on fuel systems technology and
the development of new fuel systems products. Growth opportunities outside of
the U.S. are expected to be driven by growth in the use of two-wheeled vehicles
and the increased use of gasoline-powered portable equipment in developing
countries.
 
     Emphasis on Engine Management Systems and New Product
Development. Historically, exhaust emissions of gasoline-powered small engines
were unregulated. In 1992, the California Air Resources Board promulgated
comprehensive air quality regulations limiting small engine emissions, which
regulations became effective in August 1995. A more stringent phase is scheduled
to become effective in 1999. In addition, the EPA has implemented similar
regulations that became effective in August 1996, with a more stringent phase
expected to be phased in beginning 2002. The products designed to meet these new
emission standards in the small engine market will require more sophisticated
product research and new production capabilities. The increased technological
content and sophistication required to meet emission regulations is expected to
result in lower unit sales with greater value added per product and higher unit
prices.
 
     Growing Demand in Developing Countries. The Company expects significant
growth in the demand for float feed carburetors in developing countries as per
capita income increases and two-wheeled vehicles become more affordable.
Production of two-wheeled vehicles in The People's Republic of China, for
example, increased from approximately 49,000 units in 1980 to approximately 3.4
million in 1993, 5.2 million in 1994 and 7.8 million in 1995. In addition,
management believes demand for diaphragm carburetors used in gasoline-powered
portable tools will grow in these developing countries. The inaccessibility of
electrical power distribution and geographic isolation of many projects, such as
the clearing of land and highway construction, hinder the use of
electric-powered equipment.
 
  SMALL ENGINE BUSINESS STRATEGY
 
     To respond to the promulgation of increasingly strict emission regulations
in the small engine industry, the Company is working to develop a small engine
management system which will comply with new emission standards. As the leading
developer of fuel systems technology for portable engines, the Company is well
positioned to draw upon its expertise in carburetor and ignition system design
and development, as well as its experience in responding to emissions-driven
challenges in the automotive sector. The Company's advanced product design and
development facilities in Michigan and Japan, which are equipped with
sophisticated emission measurement instruments, provide the Company with the
facilities necessary to develop more sophisticated small engine management
systems.
 
     In addition to developing new technologies, the Company intends to grow its
small engine business through expansion into foreign markets. The Company's
presence in developing countries such as The People's Republic of China will
allow it to benefit from the growing market for carburetors for two-wheeled
vehicles and from infrastructure development which requires portable power
tools.
 
                                       37

  SMALL ENGINE PRODUCTS
 
     The Company was founded as a manufacturer of carburetors for small engine
products such as lawn mowers and marine engines, and later expanded its customer
base to include manufacturers of chain saws, weed trimmers, snow blowers and
two-wheeled vehicles. The Company's carburetor technology has continually
evolved, with the Company now manufacturing diaphragm and float feed
carburetors, ignition systems and other components for small engine products and
aftermarket applications. The Company's diaphragm carburetor, float feed
carburetor and ignition system sales accounted for 53%, 23% and 6%,
respectively, of the Company's 1995 small engine net sales. The remaining 18% of
small engine net sales consisted of aftermarket sales.
 
     The diaphragm carburetor uses a diaphragm and a series of interconnected
passages to draw and regulate the amount of fuel delivered to the engine from
the fuel tank. The Company manufactures several basic models of diaphragm
carburetors from which are derived numerous variations. Diaphragm carburetors
are used on chain saw and weed trimmer engines because they will operate in any
position and minimize vapor lock. The Company believes that it is the world's
largest manufacturer of small engine diaphragm carburetors.
 
     The float feed carburetor uses a float in a reservoir of fuel to regulate
the amount of fuel delivered to the engine. In contrast to the diaphragm
carburetor, which operates in all positions, the float feed carburetor operates
only in an upright position. The Company manufactures several basic models of
float feed carburetors from which are derived numerous variations. The Company's
float feed carburetors are used on engines for lawn mowers, garden tractors,
two-wheeled vehicles, marine outboard engines, generators and industrial
engines.
 
     The ignition system uses rotating magnets in a flywheel, which induce an
electrical charge in the ignition module. The ignition module releases this
charge to the spark plug. The Company's ignition systems are used predominantly
in chain saw and weed trimmer applications.
 
     In response to California and proposed EPA air quality regulations, the
Company is integrating its carburetor and ignition technology to develop an
engine management system which will electronically control both fuel delivery
and ignition functions to limit exhaust emissions. The Company has successfully
refined existing carburetors through the incorporation of extremely close
tolerances which provide more accurate control of the fuel/air mixture to meet
the first set of standards that became effective in California in 1995 and
nationwide in 1996. Company engineers are developing new technology to meet the
subsequent requirements which will become effective in California in 1999 and
nationwide during the period 2002 to 2005. This development effort focuses on
complete engine management systems that control air flow, fuel delivery and
ignition timing to enhance fuel efficiency and reduce pollution.
 
     The Company has acquired an exclusive license to apply electronic fuel
injection to two stroke engines. It has operating prototypes for outboard marine
(including personal watercraft) and snowmobile applications. The Company
believes that this technology known as "side wall injection" offers competitive
and performance benefits and expects to obtain new supply contracts beginning in
1998. Also, the Company has developed an all-mechanical fuel injection system
for application to small displacement (150 cc or less) two-wheeled vehicles.
This system has also been presented as an operating prototype to potential
customers.
 
  SMALL ENGINE MARKETS AND CUSTOMER BASE
 
     The Company sells its small engine products in a global market. Carburetors
and small engine ignitions are sold by the Company's sales and engineering staff
directly to engine manufacturers. The Company sells a major portion of its
diaphragm carburetors to most of the leading chain saw and weed trimmer
manufacturers, including Poulan/Weedeater, Deere and Company (Homelite), Stihl
Incorporated, McCulloch Corporation, Ryobi Ltd. and Kioritz (Echo) Corporation.
The Company sells float feed carburetors to several of the leading manufacturers
of small engines, including Briggs & Stratton Corporation, the world's largest
small engine manufacturer. Mercury Marine, a major outboard engine manufacturer,
buys all of its outboard engine carburetors from the Company.
 
                                       38
<PAGE>   40
 
     One of the Company's opportunities for growth in the small engine industry
is the Chinese market. In January 1994, the Company acquired a 60% interest,
increased to 70% in 1995, in Fujian Hualong Carburetor Co., Ltd. (Fujian) which
manufactures and markets carburetors for two-wheeled vehicles in The People's
Republic of China. In addition, the Company has built a new manufacturing
facility in Tianjin to provide additional capacity to take advantage of growth
in the two-wheeled vehicle market. This new facility began production in October
1996.
 
  SMALL ENGINE COMPETITION
 
     The Company has several competitors that manufacture diaphragm carburetors
for the global small engine market, including Zama Industries, Ltd., Tillotson
Commercial Motors Ltd. and Dell' Orto, some of which are divisions of large
diversified organizations which have total sales and financial resources
exceeding those of the Company. In the market for float feed carburetors, the
Company has several competitors, including Briggs & Stratton and Tecumseh
Products, both of which have greater sales and financial resources than the
Company. The Company's major competitor in the ignition systems market is R.E.
Phelon Company Inc.
 
  AFTERMARKET PRODUCTS
 
     The Company's aftermarket sales of both automotive and small engine
products are consolidated within the small engine business. The Company sells
automotive aftermarket products for both carbureted vehicle applications and
electronic fuel injection vehicle applications through independent distributors,
such as Federal-Mogul Corporation and Standard Motor Products, Inc., and jobbers
and dealers worldwide. Some automotive products are also sold to national
manufacturing and distribution organizations for sale under private brand names
or to industrial customers for use in special applications. Aftermarket sales
accounted for $25.2 million in 1995 compared to $11.3 million in 1990.
 
     The Company sells automotive aftermarket products to support its OEM
customers and to benefit from higher margins on aftermarket sales. Management
believes that the overall market size for automotive electronic fuel injection
systems components sold to the aftermarket will continue to grow as the
population of vehicles equipped with electronic fuel injection systems ages.
 
     The Company sells its own brand name small engine aftermarket products
through independent distributors, jobbers and dealers worldwide. Some of these
products are also sold to national manufacturing and distribution organizations
for sale under private brand names or to industrial customers for use in special
applications.
 
ACQUISITION AND JOINT VENTURE STRATEGY
 
     As part of a long-term strategy for growth and expansion into new
geographic and product markets, the Company may undertake select acquisitions
and strategic alliances in the form of joint ventures. The Company may make
select acquisitions of fuel systems product manufacturers whose products can be
integrated with the Company's traditional products as part of the Company's
system development focus. These acquisitions would contribute new product
technology and open new markets to the Company. In evaluating these
acquisitions, the Company seeks high quality operations which fit with the
Company's expertise in markets where it has an established customer base and a
clear vision of opportunities, thus decreasing transition costs and other
financial risks associated with corporate acquisitions. Similarly, each of the
Company's joint ventures provides the Company with the opportunity to benefit
from established customer relationships or a unique technological advancement
which the Company could not develop on its own without the risk and expense of
establishing marketing and manufacturing organizations alone. In management's
opinion, the Company's joint ventures ultimately reduce the cost of penetrating
new markets and limit the Company's financial exposure with respect to these
operations. At the present time the Company has no specific agreements with
respect to any new acquisitions or joint ventures.
 
                                       39

MANUFACTURING AND FACILITIES
 
     The Company (including the Company's joint ventures) conducts operations in
approximately 1.9 million square feet of space in a total of 31 locations. The
Company believes that substantially all of its property and equipment is in good
condition. The Company has not experienced significant limitations on its
ability to transfer products between, or sell products in, various countries.
 
     Each of the Company's manufacturing facilities practices advanced inventory
control procedures and has installed statistical process controls to insure high
levels of quality. In that regard, some of the Company's factories have received
the Ford Q1 Award and the Chrysler QE Award. In connection with its sales to
Saab, which is partially owned by General Motors, the Company's Norway facility
has been named a General Motors Supplier of the Year four years in a row
beginning in 1991. In 1995, Walbro Automotive was named a supplier of the year
by General Motors. Various other Company factories have been recognized by
customers such as Mercury Marine, Stihl and Federal-Mogul Corporation for
excellence in product quality and delivery.
 
     In addition, the Company's domestic automotive customers have cooperated in
the development of a broad based quality procedure for which their suppliers are
required to be certified. The procedure, known as QS 9000, has been derived from
the International Standards Organization's ISO 9000 procedure. General Motors
requires its Tier I suppliers to be certified by December 1997; Chrysler
requires its suppliers to be certified by July 1997; and Ford required its
suppliers to complete the self-assessment portion of the procedure during 1996
but has not set a specific date by which suppliers must be certified. The
Company has an aggressive program in place to achieve the required
certifications on or prior to such dates. Management believes that its
manufacturing facilities at Meriden, Connecticut, Caro, Michigan and Ligonier
and Ossian, Indiana will complete certification by the second quarter of 1997.
 
     When justified by volume, the Company has invested in labor-saving
automated machining, assembly and testing equipment. For example, the operation
in Meriden, Connecticut employs computer controlled molding machines to form the
Company's plastic in-tank reservoirs. These machines are individually
programmable so that variations can be reduced and refined as part of the
continuous control process. Another example is the Caro, Michigan manufacturing
facility's automated fuel pump assembly line, which is capable of producing
1,000 pumps per hour using only six persons. Over the past several years, the
Company has reduced the cost to manufacture its fuel pumps at this facility by
reducing both labor and material costs. In Ettlingen, Germany, the Company uses
a fully automated assembly line for production of plastic fuel tanks for the
Mercedes-Benz C Class. In addition to these examples of purchased automation,
the Company designs and builds major portions of its own machining and assembly
equipment. This in-house capability permits close control over the manufacturing
process and helps the Company stay competitive in both cost and quality.
 
PATENTS, RESEARCH AND PRODUCT DEVELOPMENT
 
     The Company owns approximately 150 U.S. patents and 600 international
patents in the fuel systems field and has a number of applications pending.
These patents include proprietary ownership of designs for control devices for
engines and engine systems, fuel pumps, fuel rails, fuel regulators, fuel level
sensors, fuel reservoirs and fuel system vapor control devices, carburetors and
throttle bodies, as well as ancillary devices for engine and vehicle
applications.
 
     Although these patents are significant to the Company, management believes
that in many cases the adaptation and use of the technology involved and the
proprietary process technology employed to manufacture these products are more
important. The Company maintains a systems center in Michigan for the research,
design and development of new products. The Company's engineering departments
also engage in design, development and testing. In 1995, 1994 and 1993, the
Company spent approximately $16.7 million, $12.2 million and $9.5 million,
respectively, for engineering and research and product development.
 
COMPONENTS, MATERIALS AND INVENTORY
 
     The Company has a number of sources for the components used in
manufacturing its products. The suppliers who manufacture components often
utilize tools and dies owned by the Company. If a supplier were
 
                                       40
<PAGE>   42
 
to discontinue supplying any component, it could take the Company some time to
replace the supplier; however, the Company believes its operations would not be
materially adversely affected.
 
     The Company's principal customers provide it with estimates of their annual
needs and make monthly purchase commitments. As a result, the Company does not
experience material backlog. Consequently, the Company manages its manufacturing
facilities on a just-in-time production basis and does not maintain a
significant finished product inventory.
 
EMPLOYEES
 
     As of November 30, 1996, the Company had approximately 4,650 employees. The
Company believes that its relations with its employees are satisfactory. All of
the Company's approximately 850 European plant employees are unionized. All of
the Company's United States plant employees are non-unionized except
approximately 450 employees at both of its Michigan manufacturing locations. The
Company's three-year contract with the bargaining unit for these Michigan plants
expires in November 1998.
 
REGULATION
 
     The Company's operations are subject to increasingly stringent
environmental laws and regulations governing air emissions, waste water
discharges, the generation, treatment, storage, disposal and remediation of
hazardous substances and wastes, and employee health and safety. Certain of
these laws can impose joint and several liability for releases or threatened
releases of material upon certain statutorily defined parties, including the
Company, regardless of fault or the lawfulness of the original activity or
disposal.
 
     The Company believes it is currently in material compliance with applicable
environmental laws and regulations. The Company's compliance with environmental
laws and regulations has not materially affected the results of its operations
or the conduct of its business; however, the Company cannot predict the future
effects of such laws and regulations.

                    DESCRIPTION OF THE PREFERRED SECURITIES
 
     The Preferred Securities will be issued pursuant to the terms of the
Declaration, a copy of which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The Declaration will be qualified
as an indenture under the Trust Indenture Act. Bankers Trust Company, as
Institutional Trustee, will act as indenture trustee under the Declaration for
purposes of compliance with the provisions of the Trust Indenture Act. The terms
of the Preferred Securities will include those stated in the Declaration and
those made part of the Declaration by the Trust Indenture Act. The following
summary of the material terms and provisions of the Preferred Securities does
not purport to be complete and is subject to, and qualified in its entirety by
reference to, the Declaration, the Trust Act and the Trust Indenture Act.
 
GENERAL
 
     The Declaration authorizes the Regular Trustees to issue on behalf of the
Trust the Trust Securities, which represent undivided beneficial interests in
the assets of the Trust. All of the Common Securities will be owned, directly or
indirectly, by the Company. The Common Securities rank pari passu, and payments
will be made thereon on a pro rata basis, with the Preferred Securities, except
that upon the occurrence and during the continuance of a Declaration Event of
Default, the rights of the holders of the Common Securities to receive payment
of periodic distributions and payments upon liquidation, redemption and
otherwise will be subordinated to the rights of the holders of the Preferred
Securities. The Declaration does not permit the issuance by the Trust of any
securities other than the Trust Securities or the incurrence of any indebtedness
by the Trust. Pursuant to the Declaration, the Institutional Trustee will hold
title to the Convertible Debentures purchased by the Trust for the benefit of
the holders of the Trust Securities. The payment of distributions out of money
held by the Trust, and payments upon redemption of the Preferred Securities or
liquidation of the Trust out of money held by the Trust, are guaranteed by the
Company to the extent described under "Description of the Guarantee." The
Guarantee will be held by Bankers Trust Company, the Guarantee Trustee, for the
benefit of the holders of the Preferred Securities. The Guarantee does not cover
payment of distributions when the Trust does not have sufficient available funds
to pay such distributions. In such event, the remedy of a holder of Preferred
Securities is to (i) vote to direct the Institutional Trustee to enforce the
Institutional Trustee's rights under the Convertible Debentures or (ii) if the
failure of the Trust to pay distributions is attributable to the failure of the
Company to pay interest or principal on the Convertible Debentures, to institute
a proceeding directly against the Company for enforcement of payment to such
holder of the principal of or interest on the Convertible Debentures having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder on or after the respective due date specified in the
Convertible Debentures. See "-- Voting Rights."
 
DISTRIBUTIONS
 
     Distributions on Preferred Securities will be fixed at a rate per annum of
  % of the stated liquidation amount of $25 per Preferred Security.
Distributions in arrears beyond the first date such distributions are payable
(or would be payable, if not for any Extension Period or default by the Company
on the Convertible Debentures) will bear interest thereon at the rate per annum
of      % thereof compounded quarterly. The term "distribution" as used herein
includes any such interest payable unless otherwise stated. The amount of
distributions payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months.
 
     Distributions on the Preferred Securities will be cumulative, will accrue
from the date of initial issuance and will be payable quarterly in arrears on
each March 31, June 30, September 30 and December 31, commencing March 31, 1997.
When, as and if available for payment, distributions will be made by the
Institutional Trustee, except as otherwise described below.
 
     The distribution rate and the distribution payment dates and other payment
dates for the Preferred Securities will correspond to the interest rate and
interest payment dates and other payment dates on the Convertible Debentures.
 
     The Company has the right under the Indenture to defer payments of interest
on the Convertible Debentures by extending the interest payment period from time
to time on the Convertible Debentures for an
 
                                       46
<PAGE>   48
 
Extension Period not exceeding 20 consecutive quarterly interest periods during
which no interest shall be due and payable; provided, that no such Extension
Period may extend beyond the maturity date of the Convertible Debentures. As a
consequence of the Company's extension of the interest payment period, quarterly
distributions on the Preferred Securities would be deferred (though such
distributions would continue to accrue with interest thereon compounded
quarterly since interest would continue to accrue on the Convertible Debentures)
during any such extended interest payment period. In the event that the Company
exercises its right to extend the interest payment period, then (a) the Company
shall not declare or pay dividends on, or make any distributions or liquidation
payments with respect to, or redeem, purchase or acquire any of its capital
stock (other than (i) purchases or acquisitions of shares of Common Stock in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security requiring the Company to purchase shares of
the Common Stock, (ii) as a result of a reclassification of the Company's
capital stock or the exchange or conversion of one class or series of the
Company's capital stock for another class or series of the Company's capital
stock, (iii) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged or (iv) stock dividends paid
by the Company where the dividend stock is the same stock as that on which the
dividend is paid), (b) the Company shall not make any payment of interest on or
principal of (or premium, if any, on) or repay, repurchase or redeem any debt
securities (including guarantees) issued by the Company which rank pari passu
with or junior to the Convertible Debentures and (c) the Company shall not make
any guarantee payments with respect to the foregoing (other than pursuant to the
Guarantee). Prior to the termination of any Extension Period, the Company may
further extend such Extension Period; provided, that such Extension Period,
together with all previous and further extensions thereof may not exceed 20
consecutive quarters; and provided further that no Extension Period may extend
beyond the maturity date of the Convertible Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements. See
"Description of the Convertible Debentures -- Interest" and "Description of the
Convertible Debentures -- Interest Income and Option to Extend Interest Payment
Periods." The Regular Trustees shall give the holders of the Preferred
Securities notice of any Extension Period upon receipt of notice thereof from
the Company. See "Description of the Convertible Debentures -- Interest Income
and Option to Extend Interest Payment Periods." If distributions are deferred as
a result of an Extension Period, the deferred distributions and accrued interest
thereon shall be paid to holders of record of the Preferred Securities as they
appear on the books and records of the Trust on the record date next following
the termination of such deferral period.
 
     Distributions on the Preferred Securities will be made on the dates payable
to the extent that the Trust has funds available for the payment of such
distributions in the Property Account. The Trust's funds available for
distribution to the holders of the Preferred Securities will be limited to
payments received by the Trust from the Company pursuant to the Convertible
Debentures. See "Description of the Convertible Debentures." The payment of
distributions out of monies held by the Trust is guaranteed by the Company to
the extent set forth under "Description of the Guarantee."
 
     Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the books and records of the Trust at the close of
business on the March 15, June 15, September 15 and December 15, as the case may
be, next preceding the relevant payment dates. Such distributions will be paid
through the Institutional Trustee who will hold amounts received in respect of
the Convertible Debentures in the Property Account for the benefit of the
holders of the Trust Securities. Subject to any applicable laws and regulations
and the provisions of the Declaration, each such payment will be made as
described under "-- Book-Entry Only Issuance -- The Depository Trust Company"
below. In the event that any date on which distributions are payable on the
Preferred Securities is not a Business Day, then payment of the distributions
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date. A "Business Day" shall
mean any day other than Saturday, Sunday or any other day on which banking
institutions in New York, New York, Detroit, Michigan or Wilmington, Delaware
are permitted or required by any applicable law to close.

CONVERSION RIGHTS
 
     General. Preferred Securities will be convertible at any time on or after
            , 1997 (60 days after the date of issue) and prior to the close of
business on the Business Day immediately preceding the date of repayment of such
Preferred Securities, whether at maturity or upon redemption (either at the
option of the Company or pursuant to a Tax Event), at the option of the holder
thereof and in the manner described below, into shares of Common Stock at an
initial conversion rate of      shares of Common Stock for each Preferred
Security (equivalent to a conversion price of $     per share of Common Stock),
subject to adjustment as described under "-- Conversion Price Adjustments"
below. The Trust will covenant in the Declaration not to convert Convertible
Debentures held by it except pursuant to a notice of conversion delivered to the
Institutional Trustee, as conversion agent (the "Conversion Agent"), by a holder
of Preferred Securities. A holder of a Preferred Security wishing to exercise
its conversion right will deliver an irrevocable notice of conversion, together,
if the Preferred Security is a Certificated Security (as defined herein), with
such Certificated Security, to the Conversion Agent, which shall, on behalf of
such holder, exchange such Preferred Security for a portion of the Convertible
Debentures and immediately convert such Convertible Debentures into Common
Stock. Holders may obtain copies of the required form of the notice of
conversion notice from the Conversion Agent. Procedures for converting
book-entry Preferred Securities into shares of Common Stock will differ, as
described under "-- Book-Entry Only Issuance -- The Depository Trust Company."
 
     Holders of Preferred Securities at the close of business on a distribution
record date will be entitled to receive the distribution payable on such
Preferred Securities on the corresponding distribution payment date
notwithstanding the conversion of such Preferred Securities following such
distribution record date but prior to such distribution payment date. If any
Preferred Securities are surrendered for conversion during the period from the
close of business on any record date through and including the next succeeding
distribution payment date (except any such Preferred Securities called for
redemption), such Preferred Securities when surrendered for conversion must be
accompanied by payment in next day funds of an amount equal to the distribution
which the registered holder on such record date is to receive. Except as
described above, no distribution will be payable by the Company on converted
Preferred Securities with respect to any distribution payment date subsequent to
the date of conversion. Except as provided above, neither the Trust nor the
Company will make, or be required to make, any payment, allowance or adjustment
for accumulated and unpaid distributions, whether or not in arrears, on
Preferred Securities. Each conversion will be deemed to have been effected
immediately prior to the close of business on the day on which the related
conversion notice was received by the Conversion Agent.
 
     Shares of Common Stock issued upon conversion of Preferred Securities will
be validly issued, fully paid and nonassessable. No fractional shares of Common
Stock will be issued as a result of conversion, but in lieu thereof such
fractional interest will be paid by the Company in cash based on the last
reported sale price of Common Stock on the date such Preferred Securities are
surrendered for conversion.
 
     Conversion Price Adjustments -- General. The conversion price is subject to
adjustment in certain events, including (a) the issuance of shares of Common
Stock as a dividend or a distribution with respect to Common Stock, (b)
subdivisions, combinations and reclassification of Common Stock, (c) the
issuance to all holders of Common Stock of rights or warrants entitling them
(for a period not exceeding 45 days) to subscribe for shares of Common Stock at
less than the then Current Market Price (as defined below) of the Common Stock,
(d) the distribution to holders of Common Stock of evidences of indebtedness of
the Company, securities or capital stock, cash or assets (including securities,
but excluding those rights, warrants, dividends and distributions referred to
above and dividends and distributions paid exclusively in cash), (e) a
distribution consisting exclusively of cash (excluding any cash distributions
referred to in (d) above) to all holders of Common Stock in an aggregate amount
that, together with (i) all other cash distributions (excluding any cash
distributions referred to in (d) above) made within the 12 months preceding such
distribution and (ii) any cash and the fair market value of other consideration
payable in respect of any tender offer by the Company or a subsidiary of the
Company for the Common Stock consummated within the twelve months preceding such
distribution, exceeds 12.5% of the Company's market capitalization (being the
product of the Current Market Price times the number of shares of Common Stock
then outstanding) on the date fixed for determining the stockholders entitled to
such distribution; and (f) the consummation of a tender offer

by the Company or any subsidiary of the Company for the Common Stock which
involves an aggregate consideration that, together with (X) any cash and other
consideration payable in respect of any tender offer consummated by the Company
or a subsidiary of the Company for the Common Stock consummated within the 12
months preceding the consummation of such tender offer and (Y) the aggregate
amount of all cash distributions (excluding any cash distributions referred to
in (d) above) to all holders of the Common Stock within the twelve months
preceding the consummation of such tender offer, exceeds 12.5% of the Company's
market capitalization at the date of consummation of such tender offer. "Current
Market Price" means the average of the daily closing prices for the ten
consecutive trading days selected by the Company commencing not more than 20
trading days before, and ending not later than, the day in question.
 
     The Company from time to time may reduce the conversion price of the
Convertible Debentures (and thus, the conversion price of the Preferred
Securities) by any amount selected by the Company for any period of at least 20
days, in which case the Company shall give at least 15 days' notice of such
reduction. The Company may, at its option, make such reductions in the
conversion price, in addition to those set forth above, as the Company's Board
of Directors deem advisable to avoid or diminish any income tax to holders of
Common Stock resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes. See
"United States Federal Income Taxation -- Conversion of Preferred Securities."
 
     No adjustment of the conversion price will be made upon the issuance of any
shares of Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Company and
the investment of additional optional amounts in shares of Common Stock under
any such plan. No adjustment in the conversion price will be required unless
such adjustment would require a change of at least 1% in the conversion price
then in effect; provided, however, that any adjustment that would not be
required to be made shall be carried forward and taken into account in any
subsequent adjustment. If any action would require adjustment of the conversion
price pursuant to more than one of the provisions described above, only one
adjustment shall be made and such adjustment shall be the amount of adjustment
that has the highest absolute value to the holder of the Preferred Securities.
 
     Conversion Price Adjustments -- Merger, Consolidation or Sale of Assets of
the Company. In the event that the Company shall be a party to any transaction
or series of transactions constituting a Fundamental Change (as defined below),
including, without limitation, (i) any recapitalization or reclassification of
the Common Stock (other than a change in par value or as a result of a
subdivision or combination of the Common Stock); (ii) any consolidation or
merger of the Company with or into another corporation as a result of which
holders of Common Stock shall be entitled to receive securities or other
property or assets (including cash) with respect to or in exchange for Common
Stock (other than a merger which does not result in a reclassification,
conversion, exchange or cancellation of the outstanding Common Stock); (iii) any
sale or transfer of all or substantially all of the assets of the Company; or
(iv) any compulsory share exchange, pursuant to any of which holders of Common
Stock shall be entitled to receive other securities, cash or other property or
assets, then appropriate provision shall be made so that the holders of the
Preferred Securities then outstanding shall have the right thereafter to convert
such Preferred Securities only into (x) if any such transaction does not
constitute a Common Stock Fundamental Change (as defined below), the kind and
amount of the securities, cash or other property or assets that would have been
receivable upon such recapitalization, reclassification, consolidation, merger,
sale, transfer or share exchange by a holder of the number of shares of Common
Stock issuable upon conversion of such Preferred Securities immediately prior to
such recapitalization, reclassification, consolidation, merger, sale, transfer
or share exchange, after, in the case of a Non-Stock Fundamental Change (as
defined below), giving effect to any adjustment in the conversion price in
accordance with clause (i) of the following paragraph, and (y) if any such
transaction constitutes a Common Stock Fundamental Change, shares of common
stock of the kind received by holders of Common Stock as a result of such Common
Stock Fundamental Change in an amount determined in accordance with clause (ii)
of the following paragraph. The company formed by such consolidation or
resulting from such merger or which acquires such assets or which acquires the
Common Stock, as the case may be, shall enter into a supplemental indenture with
the Indenture Trustee, satisfactory in form to the Indenture Trustee and
executed and delivered to the Indenture Trustee, the provisions of which shall
establish
 
                                       49
<PAGE>   51
 
such right. Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as practical to the relevant adjustments provided for in
the preceding paragraphs and in this paragraph.
 
     Notwithstanding any other provision in the preceding paragraphs, if any
Fundamental Change occurs, the conversion price in effect will be adjusted
immediately after that Fundamental Change as follows:
 
          (i) in the case of a Non-Stock Fundamental Change, the conversion
     price per share of Common Stock immediately following such Non-Stock
     Fundamental Change will be the lower of (A) the conversion price in effect
     immediately prior to such Non-Stock Fundamental Change, but after giving
     effect to any other prior adjustments effected pursuant to the preceding
     paragraphs, and (B) the product of (X) the greater of the Applicable Price
     (as defined below) and the then applicable Reference Market Price (as
     defined below) and (Y) a fraction, the numerator of which is $25 and the
     denominator of which is (I) the applicable Redemption Price for one
     Preferred Security if the redemption date were the date of such Non-Stock
     Fundamental Change ($   , if such change occurs before             , 2000)
     plus (II) any then-accrued but unpaid distributions on one Preferred
     Security; and
 
          (ii) in the case of a Common Stock Fundamental Change, the conversion
     price per share of Common Stock immediately following the Common Stock
     Fundamental Change will be the conversion price in effect immediately prior
     to the Common Stock Fundamental Change, but after giving effect to any
     other prior adjustments effected pursuant to the preceding paragraphs,
     multiplied by a fraction, the numerator of which is the Purchaser Stock
     Price (as defined below) and the denominator of which is the Applicable
     Price; provided, however, that in the event of a Common Stock Fundamental
     Change in which (A) 100% of the value of the consideration received by a
     holder of Common Stock (subject to certain limited exceptions) is shares of
     common stock of the successor, acquiror or other third party (and cash, if
     any, paid with respect to any fractional interests in the shares of common
     stock resulting from the Common Stock Fundamental Change) and (B) all of
     the Common Stock (subject to certain limited exceptions) shall have been
     exchanged for, converted into, or acquired for, shares of common stock (and
     cash, if any, with respect to fractional interests) of the successor,
     acquiror or other third party, the conversion price per share of Common
     Stock immediately following the Common Stock Fundamental Change shall be
     the conversion price in effect immediately prior to the Common Stock
     Fundamental Change divided by the number of shares of common stock of the
     successor, acquiror, or other third party received by a holder of one share
     of Common Stock as a result of the Common Stock Fundamental Change.
 
     The foregoing conversion price adjustments are designed, in "Fundamental
Change" transactions where all or substantially all of the Common Stock is
converted into securities, cash, or property and not more than 50% of the value
received by the holders of Common Stock consists of stock listed or admitted for
listing subject to notice of issuance on a national securities exchange or
quoted on the NNM (a "Non-Stock Fundamental Change," as defined herein), to
increase the securities, cash or property into which each Preferred Security is
convertible.
 
     In a Non-Stock Fundamental Change transaction where the initial value
received per share of Common Stock (measured as described in the definition of
Applicable Price below) is lower than the then applicable conversion price of
the Preferred Securities but greater than or equal to the Reference Market
Price, the conversion price will be adjusted as described above with the effect
that each Preferred Security will be convertible into securities, cash or
property of the same type received by the holders of Common Stock in such
transaction but in an amount per Preferred Security equal to the amount
indicated as the denominator as of the date of such transaction as set forth in
clause (i) above with respect to conversion prices for Non-Stock Fundamental
Changes.
 
     In a Non-Stock Fundamental Change transaction where the initial value
received per share of Common Stock (measured as described in the definition of
Applicable Price below) is lower than both the conversion price of a Preferred
Security and the Reference Market Price, the conversion price will be adjusted
as described above but calculated as though such initial value had been the
Reference Market Price.
 
                                       50
<PAGE>   52
 
     In a Fundamental Change transaction where all or substantially all the
Common Stock is converted into securities, cash, or property and more than 50%
of the value received by the holders of Common Stock (subject to certain limited
exceptions) consists of listed or NNM traded common stock (a "Common Stock
Fundamental Change," as defined herein), the foregoing adjustments are designed
to provide in effect that (a) where Common Stock is converted partly into such
common stock and partly into other securities, cash, or property, each Preferred
Security will be convertible solely into a number of shares of such common stock
determined so that the initial value of such shares (measured as described in
the definition of Purchaser Stock Price below) equals the value of the shares of
Common Stock into which such Preferred Security was convertible immediately
before the transaction (measured as aforesaid) and (b) where Common Stock is
converted solely into such common stock, each Preferred Security will be
convertible into the same number of shares of such common stock receivable by a
holder of the number of shares of Common Stock into which such Preferred
Security was convertible before such transaction.
 
     In determining the amount and type of consideration received by a holder of
Common Stock in the event of a Fundamental Change, consideration received by a
holder of Common Stock pursuant to a statutory right of appraisal will be
disregarded.
 
     "Applicable Price" means (i) in the event of a Non-Stock Fundamental Change
in which the holders of Common Stock receive only cash, the amount of cash
receivable by a holder of one share of Common Stock and (ii) in the event of any
other Fundamental Change, the Current Market Price for one share of Common Stock
on the record date for the determination of the holders of Common Stock entitled
to receive cash, securities, property or other assets in connection with such
Fundamental Change or, if there is no such record date, on the date on which the
holders of the Common Stock will have the right to receive such cash,
securities, property or other assets.
 
     "Common Stock Fundamental Change" means any Fundamental Change in which
more than 50% of the value (as determined in good faith by the Company's Board
of Directors) of the consideration received by holders of Common Stock (subject
to certain limited exceptions) pursuant to such transaction consists of shares
of common stock that, for the twenty consecutive trading days immediately prior
to such Fundamental Change, has been admitted for listing or admitted for
listing subject to notice of issuance on a national securities exchange or
quoted on the NNM, provided, however, that a Fundamental Change will not be a
Common Stock Fundamental Change unless either (i) the Company continues to exist
after the occurrence of such Fundamental Change and the outstanding Preferred
Securities continue to exist as outstanding Preferred Securities, or (ii) the
outstanding Preferred Securities continue to exist as Preferred Securities and
are convertible into shares of common stock of the successor to the Company.
 
     "Fundamental Change" means the occurrence of any transaction or event or
series of transactions or events pursuant to which all or substantially all of
the Common Stock is exchanged for, converted into, acquired for or constitutes
solely the right to receive cash, securities, property or other assets (whether
by means of an exchange offer, liquidation, tender offer, consolidation, merger,
combination, reclassification, recapitalization or otherwise); provided,
however, in the case of a plan involving more than one such transaction or
event, for purposes of adjustment of the conversion price, such Fundamental
Change will be deemed to have occurred when substantially all of the Common
Stock has been exchanged for, converted into, or acquired for or constitutes
solely the right to receive cash, securities, property or other assets but the
adjustment shall be based upon the consideration that the holders of Common
Stock received in the transaction or event as a result of which more than 50% of
the Common Stock shall have been exchanged for, converted into, or acquired for,
or shall constitute solely the right to receive such cash, securities, property
or other assets.
 
     "Non-Stock Fundamental Change" means any Fundamental Change other than a
Common Stock Fundamental Change.
 
     "Purchaser Stock Price" means, with respect to any Common Stock Fundamental
Change, the Current Market Price of common stock received by holders of Common
Stock in such Common Stock Fundamental Change on the record date for the
determination of the holders of Common Stock entitled to receive such
 
                                       51
<PAGE>   53
 
shares of common stock or, if there is no such record date, on the date upon
which the holders of Common Stock shall have the right to receive such shares of
common stock.
 
     "Reference Market Price" will initially mean $          (which, unless
otherwise specified in this Prospectus, will be 66 2/3% of the last reported
sale price per share of Common Stock on the NNM on                , 1997) and,
in the event of any adjustment to the conversion price other than as a result of
a Fundamental Change, the Reference Market Price will also be adjusted so that
the ratio of the Reference Market Price to the conversion price after giving
effect to any adjustment will always be the same as the ratio of the initial
Reference Market Price to the initial conversion price of the Preferred
Securities.
 
     Conversion price adjustments or omissions in making such adjustments may,
under certain circumstances, be deemed to be distributions that could be taxable
as dividends to holders of Preferred Securities or to the holders of Common
Stock. See "United States Federal Income Taxation -- Conversion of Preferred
Securities."
 
MANDATORY REDEMPTION OF TRUST SECURITIES
 
     The Preferred Securities have no stated maturity date but will be redeemed
upon the maturity of the Convertible Debentures or to the extent the Convertible
Debentures are redeemed. The Convertible Debentures will mature on
               , 2017. Upon redemption of the Convertible Debentures at the
option of the Company, in whole or in part, at any time on or after
            , 2000 (as described under "Description of the Convertible
Debentures -- Optional Redemption"), the Institutional Trustee shall
simultaneously use the proceeds from such redemption to redeem Trust Securities
with an aggregate liquidation amount equal to the aggregate principal amount of
the Convertible Debentures redeemed by the Company at the redemption prices
(expressed as a percentage of the liquidation amount) specified below for the
twelve month period commencing             , in the year indicated
(            , in the case of 2000):

plus, in each case, accrued and unpaid distributions (including distributions
with respect to Additional Interest and Compound Interest, if any, on the
corresponding Convertible Debentures so redeemed) to the date set for
redemption.
 
     Upon the redemption of the Convertible Debentures by the Company, in whole
or in part, at any time in certain circumstances upon the occurrence of a Tax
Event described under "-- Special Event Redemption or Distribution," the
Institutional Trustee shall simultaneously use the proceeds from such redemption
to redeem Trust Securities with an aggregate liquidation amount equal to the
aggregate principal amount of the Convertible Debentures redeemed by the Company
at a redemption price equal to 100% of the liquidation amount thereof plus
accrued and unpaid distributions (including distributions with respect to
Additional Interest and Compound Interest, if any, on the corresponding
Convertible Debentures so redeemed) to the date set for redemption (subject to
the right of holders of the relevant record date to receive distributions due on
the applicable distribution payment date that is on or prior to the redemption
date).
 
     Holders of the Trust Securities shall be given not less than 30 nor more
than 60 days' notice of any redemption. In the event that fewer than all of the
outstanding Preferred Securities are to be redeemed, the Preferred Securities
will be redeemed pro rata as described under "-- Book-Entry Only Issuance -- The
Depository Trust Company" below.

SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
     As used herein, "Tax Event" means that the Regular Trustees shall have
received an opinion of nationally recognized independent tax counsel experienced
in such matters (a "Dissolution Tax Opinion") to the effect that as a result of
(a) any amendment to, or change (including any announced prospective change) in,
the laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein or (b) any amendment to, or
change in, an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority (including
the enactment of any legislation and the publication of any judicial decision or
regulatory determination on or after the date of this Prospectus), in either
case after the date of this Prospectus, there is more than an insubstantial risk
that (i) the Trust would be subject to United States federal income tax with
respect to income accrued or received on the Convertible Debentures, (ii) the
Trust would be subject to more than a de minimis amount of other taxes, duties
or other governmental charges or (iii) interest payable by the Company to the
Trust on the Convertible Debentures would not be deductible, in whole or in
part, by the Company for United States federal income tax purposes.
 
     As used herein, "Investment Company Event" means that the Regular Trustees
shall have received an opinion of a nationally recognized independent counsel
experienced in practicing under the Investment Company Act of 1940, as amended
(the "1940 Act"), 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 (a "Change in 1940 Act Law"), there is more than an insubstantial risk
that the Trust is or will be considered an "investment company" which is
required to be registered under the 1940 Act, which Change in 1940 Act Law
becomes effective on or after the date of this Prospectus.
 
     If, at any time, a Tax Event or an Investment Company Event shall occur and
be continuing, the Trust shall, except in the limited circumstances described
below, be dissolved with the result that Convertible Debentures, with an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the distribution rate of, with accrued and
unpaid interest equal to accrued and unpaid distributions on, and having the
same record date for payment as, the Preferred Securities outstanding at such
time, would be distributed to the holders of the Trust Securities in liquidation
of such holders' interests in the Trust, on a pro rata basis within 90 days
following the occurrence of such Special Event; provided, however, that in the
case of the occurrence of a Tax Event, such dissolution and distribution shall
be conditioned on the Regular Trustees receipt of an opinion of nationally
recognized independent tax counsel experienced in such matters (a "No
Recognition Opinion"), which opinion may rely on, among other things, published
revenue rulings of the Internal Revenue Service, to the effect that the holders
of the Preferred Securities will not recognize any gain or loss for United
States federal income tax purposes as a result of such dissolution and
distribution of Convertible Debentures; and, provided, further, that if at the
time there is available to the Company or the Trust the opportunity to
eliminate, within such 90-day period, the Special Event by taking some
ministerial action, such as filing a form or making an election, or pursuing
some other similar reasonable measure that, in the sole judgment of the Company,
has or will cause no adverse effect on the Trust, the Company or the holders of
the Trust Securities, the Company or the Trust will pursue such measure in lieu
of dissolution. Furthermore, if in the case of the occurrence of a Tax Event,
(i) the Company has received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of such Tax Event, there is more than an insubstantial risk that the
Company would be precluded from deducting the interest on the Convertible
Debentures for United States federal income tax purposes, even after the
Convertible Debentures were distributed to the holders of Preferred Securities
in liquidation of such holders' interests in the Trust as described above, or
(ii) the Regular Trustees shall have been informed by such tax counsel that it
cannot deliver a No Recognition Opinion to the Regular Trustees, the Company
shall have the right, upon not less than 30 nor more than 60 days' notice to the
holders of the Preferred Securities, to redeem the Convertible Debentures, in
whole or in part, for cash within 90 days following the occurrence of such Tax
Event, and following such redemption, Preferred Securities with an aggregate
liquidation amount equal to the aggregate principal amount of Convertible
Debentures so redeemed shall be redeemed by the Trust at the Redemption Price on
a pro rata basis; provided, however, that if at the
 
                                       53
<PAGE>   55
 
time there is available to the Company or the Trust the opportunity to
eliminate, within such 90-day period, the Tax Event by taking some ministerial
action, such as filing a form or making an election, or pursuing some other
similar reasonable measure that, in the sole judgment of the Company, will have
no adverse effect on the Trust, the Company or the holders of the Trust
Securities, the Company or the Trust will pursue such measure in lieu of
redemption.
 
     If the Convertible Debentures are distributed to the holders of the
Preferred Securities, the Company will use its best efforts to cause the
Convertible Debentures to be quoted on the NNM or on such other exchange as the
Preferred Securities are then listed.
 
     After the date fixed for any distribution of Convertible Debentures upon
dissolution of the Trust, (i) the Preferred Securities will no longer be deemed
to be outstanding, (ii) the securities depositary or its nominee, as the record
holder of the Preferred Securities, will receive a registered global certificate
or certificates representing the Convertible Debentures to be delivered to the
holders of the Preferred Securities upon such distribution and (iii) any
certificates representing Preferred Securities not held by the securities
depositary or its nominee will be deemed to represent Convertible Debentures
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the distribution rate of, and with
accrued and unpaid interest equal to accrued and unpaid distributions on, such
Preferred Securities until such certificates are presented to the Company or its
agent for transfer or reissuance.
 
     There can be no assurance as to the market prices for either the Preferred
Securities or the Convertible Debentures that may be distributed in exchange for
Trust Securities if a dissolution and liquidation of the Trust were to occur.
Accordingly, the Preferred Securities that an investor may purchase, whether
pursuant to the offer made hereby or in the secondary market, or the Convertible
Debentures that the investor may receive if a dissolution and liquidation of the
Trust were to occur, may trade at a discount to the price the investor paid to
purchase Preferred Securities.
 
REDEMPTION PROCEDURES
 
     The Trust may not redeem fewer than all of the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Preferred Securities for all quarterly distribution periods occurring on or
prior to the date of redemption.
 
     If the Trust gives a notice of redemption in respect of Preferred
Securities (which notice will be irrevocable), then, if the Company has paid to
the Institutional Trustee a sufficient amount of cash in connection with the
related redemption or maturity of the Convertible Debentures by 12:00 noon New
York City time on the redemption date, the Preferred Securities represented by
the Global Certificates will irrevocably deposit (i) with DTC, funds sufficient
to pay the applicable Redemption Price on redemption of all Preferred Securities
represented by the Global Certificates and will give DTC irrevocable
instructions and authority to pay such amount in respect of Preferred Securities
represented by the Global Certificates (as defined herein) and (ii) with the
paying agent for the Preferred Securities, funds sufficient to pay such amount
in respect of any Certificated Securities and will give such paying agent
irrevocable instructions and authority to pay such amount to the holders of
Certificated Securities upon surrender of their certificates. If notice of
redemption shall have been given and funds are deposited as required, then
immediately prior to the close of business on the date of such deposit
distributions will cease to accrue and all rights of holders of Preferred
Securities so called for redemption will cease, except the right of the holders
of such Preferred Securities to receive the Redemption Price, but without
interest on such Redemption Price. In the event that any date fixed for
redemption of Preferred Securities is not a Business Day, then payment of the
applicable Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (without any interest or other payment in
respect of any such delay), except that, if such Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day. In the event that payment of the Redemption Price in respect of Preferred
Securities is improperly withheld or refused and not paid either by the Trust or
by the Company pursuant to the Guarantee, distributions on such Preferred
Securities will continue to accrue at the then applicable rate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
Redemption Price.
 
                                       54
<PAGE>   56
 
     In the event that fewer than all of the outstanding Preferred Securities
are to be redeemed, the Preferred Securities will be redeemed in accordance with
DTC's standard procedures. See "-- Book-Entry Only Issuance -- The Depository
Trust Company."
 
     Subject to the foregoing and applicable law (including, without limitation,
United States federal securities laws), the Company or its subsidiaries may at
any time, and from time to time, purchase outstanding Preferred Securities by
tender, in the open market or by private agreement.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of distributions on, and the amount payable upon redemption of, the
Trust Securities, as applicable, shall be made pro rata based on the liquidation
amount of the Trust Securities; provided, however, that, if on any distribution
date or redemption date a Declaration Event of Default shall have occurred and
be continuing, no payment of any distribution on, or amount payable upon
redemption of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid distributions on
all outstanding Preferred Securities for all distribution periods terminating on
or prior thereto, or in the case of payment of the amount payable upon
redemption of the Preferred Securities, all of such amount in respect of all
outstanding Preferred Securities shall have been made or provided for, and all
funds available to the Institutional Trustee shall first be applied to the
payment in full in cash of all distributions on, or the amount payable upon
redemption of, Preferred Securities then due and payable.
 
     In the case of any Declaration Event of Default, the holders of Common
Securities will be deemed to have waived any such Declaration Event of Default
with respect to the Common Securities until all such Declaration Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Declaration Events of Default with respect
to the Preferred Securities have been so cured, waived or otherwise eliminated,
the Institutional Trustee will act solely on behalf of the holders of the
Preferred Securities and not the holders of the Common Securities, and only the
holders of the Preferred Securities will have the right to direct the
Institutional Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     In the event of any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust (each, a "Liquidation"), the holders of
the Preferred Securities will be entitled to receive out of the assets of the
Trust, after satisfaction of liabilities to creditors, distributions in an
amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security plus accrued and unpaid distributions thereon to the date of
payment (the "Liquidation Distribution"), unless, in connection with such
Liquidation, Convertible Debentures in an aggregate stated principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the distribution rate of, and accrued and unpaid interest equal to
accrued and unpaid distributions on, the Preferred Securities outstanding at
such time have been distributed on a pro rata basis to the holders of the
Preferred Securities.
 
     If, upon any such Liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities shall be paid on a pro rata basis. The holders
of the Common Securities will be entitled to receive distributions upon any such
dissolution pro rata with the holders of the Preferred Securities, except that
if a Declaration Event of Default has occurred and is continuing, the holders of
the Common Securities shall not be permitted to receive such distributions until
such Declaration Event of Default has been cured.
 
     Pursuant to the Declaration, the Trust shall terminate (i) upon the
bankruptcy of the Company or the holder of the Common Securities; (ii) upon the
filing of a certificate of dissolution or its equivalent with respect to the
holder of the Common Securities or the Company, the filing of a certificate of
cancellation with respect to the Trust after having obtained the consent of at
least a majority in liquidation amount of the Trust Securities, voting together
as a single class, to file such certificate of cancellation, or the revocation
of the charter of the Company or the holder of the Common Securities and the
expiration of 90 days after the date of
 
                                       55
<PAGE>   57
 
revocation without a reinstatement thereof; (iii) upon the entry of a decree of
judicial dissolution of the holder of the Common Securities, the Company or the
Trust; (iv) when all of the Trust Securities shall have been called for
redemption and the amounts necessary for redemption thereof, including any
Additional Interest, shall have been paid to the holders thereof in accordance
with the terms of the Trust Securities; (v) upon the distribution of Convertible
Debentures upon the occurrence of a Special Event; or (vi) the expiration of the
term of the Trust.
 
DECLARATION EVENTS OF DEFAULT
 
     An event of default under the Indenture (an "Indenture Event of Default")
constitutes an event of default under the Declaration with respect to the Trust
Securities (a "Declaration Event of Default"); provided, that pursuant to the
Declaration, the holder of the Common Securities will be deemed to have waived
any Declaration Event of Default with respect to the Common Securities until all
Declaration Events of Default with respect to the Preferred Securities have been
cured, waived or otherwise eliminated. Until such Declaration Events of Default
with respect to the Preferred Securities have been so cured, waived or otherwise
eliminated, the Institutional Trustee will be deemed to be acting solely on
behalf of the holders of the Preferred Securities, and only the holders of the
Preferred Securities will have the right to direct the Institutional Trustee
with respect to certain matters under the Declaration and, therefore, the
Indenture. In the event any Declaration Event of Default with respect to the
Preferred Securities is waived by the holders of the Preferred Securities as
provided in the Declaration, the holders of Common Securities pursuant to the
Declaration have agreed that such waiver also constitutes a waiver of such
Declaration Event of Default with respect to the Common Securities for all
purposes under the Declaration without any further act, vote or consent of the
holders of Common Securities. See "-- Voting Rights." The Institutional Trustee
shall notify all holders of the Preferred Securities of any notice of default
received from the Indenture Trustee with respect to the Convertible Debentures.
Such notice shall state that such Indenture Event of Default also constitutes a
Declaration Event of Default.
 
     If the Institutional Trustee fails to enforce its rights under the
Convertible Debentures, to the fullest extent permitted by law, any holder of
Preferred Securities may directly institute a legal proceeding against the
Company to enforce the Institutional Trustee's rights under the Convertible
Debentures without first instituting any legal proceeding against the
Institutional Trustee or any other person or entity. If a Declaration Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on the Convertible
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, the redemption date), then a holder of Preferred
Securities may also directly institute a proceeding for enforcement of payment
to such holder of the principal of or interest on the Convertible Debentures
having a principal amount equal to the aggregate liquidation amount of the
Preferred Securities of such holder on or after the respective due date
specified in the Convertible Debentures without first (i) directing the
Institutional Trustee to enforce the terms of the Convertible Debentures or (ii)
instituting a legal proceeding against the Company to enforce the Institutional
Trustee's rights under the Convertible Debentures. In connection with such
Direct Action, the Company will be subrogated to the rights of such holder of
Preferred Securities under the Declaration to the extent of any payment made by
the Company to such holder of Preferred Securities in such Direct Action.
Consequently, the Company 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 the Trust. The holders of Preferred Securities will not be
able to exercise directly any other remedy available to the holders of the
Convertible Debentures.
 
     Upon the occurrence of an Indenture Event of Default, the Institutional
Trustee as the sole holder of the Convertible Debentures will have the right
under the Indenture to declare the principal of and interest on the Convertible
Debentures to be immediately due and payable. The Company and the Trust are each
required to file annually with the Institutional Trustee an officers'
certificate as to its compliance with all conditions and covenants under the
Declaration.

VOTING RIGHTS
 
     Except as described in this Prospectus under "Description of the Guarantee
- -- Modification of the Guarantee; Assignment," and except as provided under the
Trust Act and the Trust Indenture Act and as otherwise required by law and the
Declaration, the holders of the Preferred Securities will have no voting rights.
 
     Subject to the requirement of the Institutional Trustee obtaining a tax
opinion in certain circumstances set forth in the last sentence of this
paragraph, the holders of a majority in aggregate liquidation amount of the
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Institutional Trustee
or direct the exercise of any trust or power conferred upon the Institutional
Trustee under the Declaration, including the right to direct the Institutional
Trustee, as holder of the Convertible Debentures, to (i) 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 Convertible Debentures, (ii) waive any past Indenture Event
of Default that is waivable under the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Convertible
Debentures shall be due and payable or (iv) consent to any amendment,
modification or termination of the Indenture or the Convertible Debentures where
such consent shall be required; provided, however, that where a consent or
action under the Indenture would require the consent or act of the holders of
more than a majority in principal amount of Convertible Debentures (a "Super
Majority") affected thereby, only the holders of at least such Super Majority in
aggregate liquidation amount of the Preferred Securities may direct the
Institutional Trustee to give such consent or take such action. If the
Institutional Trustee fails to enforce its rights under the Convertible
Debentures, any record holder of Preferred Securities may directly institute a
legal proceeding against the Company to enforce the Institutional Trustee's
rights under the Convertible Debentures without first instituting any legal
proceeding against the Institutional Trustee or any other person or entity. The
Institutional Trustee shall notify all holders of the Preferred Securities of
any notice of default received from the Indenture Trustee with respect to the
Convertible Debentures. Such notice shall state that such Indenture Event of
Default also constitutes a Declaration Event of Default. Except with respect to
directing the time, method and place of conducting a proceeding for a remedy
available to the Institutional Trustee, the Institutional Trustee, as holder of
the Convertible Debentures, shall not take any of the actions described in
clauses (i), (ii), (iii) or (iv) above unless the Institutional Trustee has
obtained an opinion of independent tax counsel experienced in such matters to
the effect that as a result of such action, the Trust will not fail to be
classified as a grantor trust for United States federal income tax purposes.
 
     In the event the consent of the Institutional Trustee, as the holder of the
Convertible Debentures, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture, the Institutional
Trustee shall request the written direction of the holders of the Trust
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification or termination as directed by
a majority in liquidation amount of the Trust Securities voting together as a
single class; provided, however, that where any amendment, modification or
termination under the Indenture would require the consent of a Super Majority,
the Institutional Trustee may only give such consent at the direction of the
holders of at least the proportion in aggregate stated liquidation amount of the
Trust Securities which the relevant Super Majority represents of the aggregate
principal amount of the Convertible Debentures outstanding. The Institutional
Trustee shall be under no obligation to take any such action in accordance with
the direction of the holders of the Trust Securities unless the Institutional
Trustee has obtained an opinion of a nationally recognized independent tax
counsel experienced in such matters to the effect that for United States federal
income tax purposes the Trust will not be classified as other than a grantor
trust.
 
     A waiver of an Indenture Event of Default will constitute a waiver of the
corresponding Declaration Event of Default.
 
     Any required approval or direction of holders of Preferred Securities may
be given at a separate meeting of holders of Preferred Securities convened for
such purpose, at a meeting of all of the holders of Trust Securities or pursuant
to written consent. The Regular Trustees will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of
 
                                       57
<PAGE>   59
 
such holders is to be taken, to be mailed to each holder of record of Preferred
Securities. Each such notice will include a statement setting forth the
following information: (i) the date of such meeting or the date by which such
action is to be taken; (ii) a description of any resolution proposed for
adoption at such meeting on which such holders are entitled to vote or of such
matter upon which written consent is sought; and (iii) instructions for the
delivery of proxies or consents. No vote or consent of the holders of Preferred
Securities will be required for the Trust to redeem and cancel Preferred
Securities or distribute Convertible Debentures in accordance with the
Declaration.
 
     Notwithstanding that holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities that are owned at such time by the Company or any entity directly or
indirectly controlling or controlled by, or under direct or indirect common
control with, the Company, shall not be entitled to vote or consent and shall,
for purposes of such vote or consent, be treated as if such Preferred Securities
were not outstanding.
 
     The procedures by which holders of Preferred Securities represented by the
Global Certificates may exercise their voting rights are described below. See
"-- Book-Entry Only Issuance -- The Depository Trust Company."
 
     Holders of the Preferred Securities will have no right to appoint or remove
any of the Trustees, who may be appointed, removed or replaced solely by the
Company as the holder of the Common Securities.
 
MODIFICATION OF THE DECLARATION
 
     The Declaration may be modified and amended if approved by the Regular
Trustees (and, in certain circumstances, the Institutional Trustee and the
Delaware Trustee), provided, that if any proposed amendment provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the holders of the
Trust Securities, whether by way of amendment to the Declaration or otherwise or
(ii) the dissolution, winding-up or termination of the Trust other than pursuant
to the terms of the Declaration, then the holders of the Trust Securities voting
together as a single class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of holders of at least a majority in liquidation amount of the Trust
Securities affected thereby; provided, that if any amendment or proposal
referred to in clause (i) above would adversely affect only the Preferred
Securities or the Common Securities, then only the affected class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of a majority in liquidation
amount of such class of Trust Securities.
 
     Notwithstanding the foregoing, no amendment or modification may be made to
the Declaration if such amendment or modification would (i) cause the Trust to
be classified for United States federal income tax purposes as other than a
grantor trust, (ii) reduce or otherwise adversely affect the powers of the
Institutional Trustee or (iii) cause the Trust to be deemed an "investment
company" that is required to be registered under the 1940 Act.
 
MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST
 
     The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any corporation or other body, except as
described below or as otherwise set forth in the Declaration. The Trust may,
with the consent of the Regular Trustees and without the consent of the holders
of the Trust Securities, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State provided, that
(i) such successor entity either (x) expressly assumes all of the obligations of
the Trust under the Trust Securities or (y) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities"), so long as the Successor Securities
rank the same as the Preferred Securities rank with respect to distributions,
assets and payments upon liquidation, redemption and otherwise, (ii) the Company
expressly acknowledges a trustee of such successor entity possessing the same
powers and duties as the Institutional Trustee, in its capacity as the holder of
the Convertible Debentures, (iii) the Preferred Securities or any Successor
Securities are listed, or any Successor Securities will be listed upon
notification of
 
                                       58
<PAGE>   60
 
issuance, on any national securities exchange or with another organization on
which the Preferred Securities are then listed or quoted, (iv) such merger,
consolidation, amalgamation or replacement does not cause the Preferred
Securities (including any Successor Securities) to be downgraded by any
nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation or replacement does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities (including
any Successor Securities) in any material respect (other than with respect to
any dilution of the holders' interest in the new entity), (vi) such successor
entity has a purpose substantially identical to that of the Trust, (vii) the
Company guarantees the obligations of such successor entity under the Successor
Securities to the same extent as provided by the Guarantee and (viii) prior to
such merger, consolidation, amalgamation or replacement, the Company has
received an opinion of a nationally recognized independent counsel to the Trust
and experienced in such matters to the effect that: (A) such merger,
consolidation, amalgamation or replacement will not adversely affect the rights,
preferences and privileges of the holders of the Trust Securities (including any
Successor Securities) in any material respect (other than with respect to any
dilution of the holders' interest in the new entity) and (B) following such
merger, consolidation, amalgamation or replacement, neither the Trust nor such
successor entity will be required to register as an "investment company" under
the 1940 Act. Notwithstanding the foregoing, the Trust shall not, except with
the consent of holders of 100% in liquidation amount of the Trust Securities,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it, if, in the opinion of a nationally recognized independent tax
counsel experienced in such matters, such consolidation, amalgamation, merger or
replacement would cause the Trust or the successor entity to be classified as
other than a grantor trust for United States federal income tax purposes. In
addition, so long as any Preferred Securities remain outstanding and are not
held entirely by the Company, the Trust may not voluntarily liquidate, dissolve,
wind-up or terminate except as described above under "-- Special Event
Redemption or Distribution."
 
BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
     The Depository Trust Company ("DTC") will act as securities depositary for
the Preferred Securities. The Preferred Securities will be issued only as
fully-registered securities registered in the name of Cede & Co. (DTC's
nominee). One or more fully-registered global Preferred Securities certificates
(the "Global Certificates"), representing the total aggregate number of
Preferred Securities, will be issued and will be deposited with DTC.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in the global Preferred
Securities as represented by a Global Certificate.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants ("Participants") deposit with DTC. DTC
also facilitates the settlement among Participants of securities transactions,
such as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct Participants
in DTC include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations (the "Direct Participants"). DTC is
owned by a number of its Direct Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc., and the National Association of
Securities Dealers, Inc. (the "NASD"). Access to the DTC system is also
available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly ("Indirect Participants"). The rules
applicable to DTC and its Participants are on file with the Commission.
 
     Purchases of Preferred Securities within the DTC system must be made by or
through Participants, which will receive a credit for the Preferred Securities
on DTC's records. The ownership interest of each actual purchaser of each
Preferred Security ("Beneficial Owner") is in turn to be recorded on the Direct
and
 
                                       59
<PAGE>   61
 
Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchases, but Beneficial Owners are expected to
receive written conformations providing details of the transactions, as well as
periodic statements of their holdings, from the Direct or Indirect Participants
through which the Beneficial Owners purchased Preferred Securities. Transfers of
ownership interests in the Preferred Securities are to be accomplished by
entries made on the books of Direct Participants acting on behalf of Beneficial
Owners. Beneficial Owners will not receive certificates representing their
ownership interests in the Preferred Securities, except in the event that use of
the book-entry system for the Preferred Securities is discontinued.
 
     To facilitate subsequent transfers, all Preferred Securities deposited by
Participants with DTC are registered in the name of DTC's nominee, Cede & Co.
The deposit of Preferred Securities with DTC and their registration in the name
of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of
the actual Beneficial Owners of the Preferred Securities. DTC's records reflect
only the identity of the Direct Participants to whose accounts such Preferred
Securities are credited, which may or may not be the Beneficial Owners. The
Participants will remain responsible for keeping account of their holdings on
behalf of their customers.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices shall be sent to Cede & Co. If less than all of the
Preferred Securities are being redeemed, DTC will reduce the amount of the
interest of each Direct Participant in such Preferred Securities in accordance
with its procedures.
 
     Although voting with respect to the Preferred Securities is limited, in
those cases where a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to the Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Direct Participants to whose accounts the Preferred
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).
 
     Distributions on the Preferred Securities will be made to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payments on such payment date.
Payments by Participants and Indirect Participants to Beneficial Owners will be
governed by standing instructions and customary practices, as is the case with
securities held for the account of customers in bearer form or registered in
"Street name," and such payments will be the responsibility of such Participants
and not of DTC, the Trust or the Company, subject to any statutory or regulatory
requirements as may be in effect from time to time. Payment of distributions to
DTC is the responsibility of the Trust, disbursement of such payments to Direct
Participants is the responsibility of DTC, and disbursement of such payments to
the Beneficial Owners is the responsibility of Direct and Indirect Participants.
 
     Except as provided herein, a Beneficial Owner of an interest in a Global
Certificate will not be entitled to receive physical delivery of Preferred
Securities. Accordingly, each Beneficial Owner must rely on the procedures of
DTC to exercise any rights under the Preferred Securities.
 
     DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
the Trust. Under such circumstances, in the event that a successor securities
depositary is not obtained, Preferred Securities certificates are required to be
printed and delivered. Additionally, the Regular Trustees (with the consent of
the Company) may decide to discontinue use of the system of book-entry transfers
through DTC (or a successor depositary) with respect to the Preferred
Securities. In that event, certificates for the Preferred Securities will be
printed and delivered.

<PAGE>   62
 
     The information in this Section concerning DTC and DTC's book-entry system
has been obtained from sources that the Trust and the Company believe to be
reliable, but neither the Trust nor the Company takes responsibility for the
accuracy thereof.
 
INFORMATION CONCERNING THE INSTITUTIONAL TRUSTEE
 
     The Institutional Trustee, prior to the occurrence of a default with
respect to the Trust Securities, undertakes to perform only such duties as are
specifically set forth in the Declaration and, after such a default, shall
exercise the same degree of care as a prudent individual would exercise in the
conduct of his own affairs. Subject to such provisions, the Institutional
Trustee is under no obligation to exercise any of the powers vested in it by the
Declaration at the request of any holder of Preferred Securities, unless offered
reasonable indemnity by such holder against the costs, expenses and liabilities
which might be incurred thereby. Notwithstanding the foregoing, the holders of
Preferred Securities will not be required to offer such indemnity in the event
such holders, by exercising their voting rights, direct the Institutional
Trustee to take any action following a Declaration Event of Default.
 
PAYING AGENT
 
     Payments in respect of the Preferred Securities represented by the Global
Certificates will be made to DTC, which will credit the relevant accounts at DTC
on the applicable distribution dates or, in the case of Certificated Securities,
such payments shall be made by check mailed to the address of the holder
entitled thereto as such address shall appear on the Register. The Paying Agent
initially will be the Institutional Trustee. The Paying Agent will be permitted
to resign as Paying Agent upon 30 days' written notice to the Trustees. In the
event that the Institutional Trustee will no longer be the Paying Agent, the
Regular Trustees shall appoint a successor to act as Paying Agent (which shall
be a bank or trust company).
 
REGISTRAR, TRANSFER AGENT AND CONVERSION AGENT
 
     The Institutional Trustee will act as Registrar, Transfer Agent and
Conversion Agent for the Preferred Securities.
 
     Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of the Trust, but upon payment (with the giving of such
indemnity as the Trust or the Company may require) in respect of any tax or
other government charges that may be imposed in relation to it.
 
     The Trust will not be required to register or cause to be registered the
transfer of Preferred Securities after such Preferred Securities have been
called for redemption.
 
GOVERNING LAW
 
     The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.
 
MISCELLANEOUS
 
     The Regular Trustees are authorized and directed to operate the Trust in
such a way that the Trust will not be deemed to be an "investment company"
required to be registered under the 1940 Act or characterized as other than a
grantor trust for United States federal income tax purposes. In this connection,
the Company and the Regular Trustees are authorized to take any action, not
inconsistent with applicable law, the certificate of trust or the Declaration
that each of the Company and the Regular Trustees determine in their discretion
to be necessary or desirable for such purposes as long as such action does not
adversely affect the interests of the holders of the Preferred Securities.
 
     Holders of the Preferred Securities have no preemptive or similar rights.
 
                                       61

                   DESCRIPTION OF THE CONVERTIBLE DEBENTURES
 
     Set forth below is a description of the specific terms of the Convertible
Debentures in which the Trust will invest the proceeds from the issuance and
sale of the Trust Securities. The following description does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
the Indenture (the "Indenture") between the Company and Bankers Trust Company,
as trustee (the "Indenture Trustee"), the form of which is filed as an exhibit
to the Registration Statement of which this Prospectus is a part. Certain
capitalized terms used herein are defined in the Indenture.
 
     Under certain circumstances involving the dissolution of the Trust
following the occurrence of a Special Event, Convertible Debentures may be
distributed to the holders of the Trust Securities in liquidation of the Trust.
See "Description of the Preferred Securities -- Special Event Redemption or
Distribution."
 
     If the Convertible Debentures are distributed to the holders of Preferred
Securities, the Company will use its best efforts to have the Convertible
Debentures quoted on the NNM or on any national securities exchange or similar
organization on which the Preferred Securities are then listed or quoted (as
defined herein).
 
GENERAL
 
     The Convertible Debentures will be issued as unsecured debt under the
Indenture. The Convertible Debentures will be limited in aggregate principal
amount to $50 million ($57.5 million if the Underwriters' over-allotment option
is exercised in full), such amount being the sum of the aggregate stated
liquidation amount of the Preferred Securities and the Common Securities.
 
     The Convertible Debentures are not subject to a sinking fund provision. The
entire principal amount of the Convertible Debentures will mature and become due
and payable, together with any accrued and unpaid interest thereon, including
Compound Interest (as defined herein) and Additional Interest (as defined
herein), if any, on               , 2017.
 
     If Convertible Debentures are distributed to holders of Preferred
Securities in liquidation of such holder's interest in the Trust, such
Convertible Debentures will initially be issued in the form of one or more
Global Securities (as defined herein under "-- Book-Entry and Settlement"
below). As described herein under certain limited circumstances, Convertible
Debentures may be issued in certificated form in exchange for a Global Security.
In the event that Convertible Debentures are issued in certificated form, such
Convertible Debentures will be in denominations of $25 and integral multiples
thereof and may be transferred or exchanged at the offices described below.
Payments on Convertible Debentures issued as a Global Security will be made to
DTC, a successor depositary or, in the event that no depositary is used, to a
Paying Agent for the Convertible Debentures. In the event Convertible Debentures
are issued in certificated form, principal and interest will be payable, the
transfer of the Convertible Debentures will be registrable and Convertible
Debentures will be exchangeable for Convertible Debentures of other
denominations of a like aggregate principal amount at the corporate trust office
of the Indenture Trustee in New York, New York; provided, that payment of
interest may be made at the option of the Company by check mailed to the address
of the persons entitled thereto.
 
     There are no covenants or provisions in the Indenture that afford holders
of Convertible Debentures protection in the event of a highly leveraged
transaction, reorganization, restructuring, merger or similar transaction
involving the Company that may adversely affect such holders.
 
SUBORDINATION
 
     The Indenture provides that the Convertible Debentures are subordinate and
junior in right of payment to all existing and future Senior Indebtedness of the
Company. No payment of principal (including redemption payments), premium, if
any, or interest (including Additional Interest and Compound Interest) on, the
Convertible Debentures may be made if (i) any Senior Indebtedness of the Company
has not been paid when due and any applicable grace period with respect to such
default has ended and such default has not been cured or waived, or ceased to
exist or (ii) the maturity of any Senior Indebtedness of the Company has been
accelerated because of a default. At September 30, 1996, after giving effect to
the application of the net proceeds of the Offering, Senior Indebtedness of the
Company aggregated approximately $272 million. Upon any distribution of assets
of the Company to creditors upon any dissolution, winding up, liquidation or
 
                                       62
<PAGE>   64
 
reorganization, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal of, and premium, if any, and
interest due or to become due on, all Senior Indebtedness of the Company must be
paid in full before the holders of the Convertible Debentures are entitled to
receive or retain any payment. Upon satisfaction of all claims related to all
Senior Indebtedness of the Company then outstanding, the rights of the holders
of the Convertible Debentures will be subrogated to the rights of the holders of
Senior Indebtedness of the Company to receive payments or distributions
applicable to Senior Indebtedness until all amounts owing on the Convertible
Debentures are paid in full.
 
     The term "Senior Indebtedness" means, with respect to the Company, (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of such
obligor for money borrowed and (B) indebtedness evidenced by securities, notes,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter of credit, banker's acceptance, security purchase
facility or similar credit transaction, (v) all obligations in respect of
interest rate swap, cap or other similar agreements, interest rate future or
option contracts, currency swap agreements, currency future or option contracts
and other similar agreements, (vi) all obligations of the type referred to in
clauses (i) through (v) above of other persons for the payment of which such
obligor is responsible or liable as obligor, guarantor or otherwise, and (vii)
all obligations of the type referred to in clauses (i) through (vi) above of
other persons secured by any lien on any property or asset of such obligor
(whether or not such obligation is assumed by such obligor), except for (1) any
such indebtedness that is by its terms subordinated to or pari passu with the
Convertible Debentures and (2) any indebtedness between or among such obligor or
its affiliates, including all other debt securities and guarantees in respect of
those debt securities, issued to (a) the Trust or a trustee of such trust and
(b) any other trust, or a trustee of such trust, partnership or other entity
affiliated with the Company that is a financing vehicle of the Company (a
"financing entity") in connection with the issuance by such financing entity of
preferred securities or other securities that rank pari passu with, or junior
to, the Preferred Securities. Such Senior Indebtedness shall continue to be
Senior Indebtedness and be entitled to the benefits of the subordination
provisions irrespective of any amendment, modification or waiver of any term of
such Senior Indebtedness.
 
     In addition, a substantial portion of the Company's operations is conducted
through its subsidiaries. At September 30, 1996, indebtedness and other
liabilities of such subsidiaries aggregated, after giving effect to the
application of the net proceeds of the Offering, approximately $369 million
(including the $272 million referred to above), which liabilities are
effectively senior to the Convertible Debentures. See "Capitalization."
 
     The Indenture does not limit the aggregate amount of Senior Indebtedness
that may be issued by the Company.
 
OPTIONAL REDEMPTION
 
     The Company shall have the right to redeem the Convertible Debentures, in
whole or in part, from time to time on or after             , 2000, at the
redemption prices (expressed as a percentage of principal amount) specified
below (the "Redemption Prices") for the twelve month period commencing
            , in the year indicated (     , in the case of 2000):

plus, in each case, accrued and unpaid interest, including Additional Interest
and Compound Interest, if any, to the date set for redemption.
 
                                       63
<PAGE>   65
 
     The Company may also redeem the Convertible Debentures, in whole or in
part, at any time in certain circumstances upon the occurrence of a Tax Event as
described under "Description of the Preferred Securities -- Special Event
Redemption or Distribution" at a redemption price equal to 100% of the principal
amount to be redeemed plus accrued and unpaid interest, including Additional
Interest and Compound Interest, if any, to the date set for redemption (subject
to the right of holders of record on the relevant record date to receive
interest due on an Interest Payment Date that is on or prior to the redemption
date).
 
     If a partial redemption of the Preferred Securities resulting from a
partial redemption of the Convertible Debentures would result in the delisting
of the Preferred Securities, the Company may only redeem Convertible Debentures
in whole.
 
PROPOSED TAX LEGISLATION
 
     On March 19, 1996, the U.S. Treasury Department proposed certain tax law
changes (the "Proposed Legislation") that would, among other things, generally
deny corporate issuers a deduction for interest in respect of certain debt
obligations, with a maximum term of more than 20 years, that are not shown as
indebtedness on the consolidated balance sheet of the issuer. The Convertible
Debentures have a maximum term of 20 years, and therefore would not be adversely
affected by passage of the Proposed Legislation, even if the Proposed
Legislation has a retroactive effective date. However, there can be no assurance
that any Proposed Legislation, if enacted, would not apply to debt obligations
with a term of 20 or fewer years, including the Convertible Debentures.
 
     On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr.
and House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that the Proposed Legislation,
if adopted by either of the tax-writing committees of Congress, would have an
effective date that is no earlier than the date of "appropriate Congressional
action." Based upon the Joint Statement, it is expected that if the Proposed
Legislation were to be enacted, such legislation would not apply to the
Convertible Debentures because they will be issued prior to the date of any
"appropriate Congressional action." There can be no assurance, however, that any
proposed legislation enacted after the date hereof will not otherwise adversely
affect the ability of the Company to deduct the interest payable on the
Convertible Debentures. Accordingly, there can be no assurance that a Tax Event
will not occur. See "Description of the Preferred Securities -- Special Event
Redemption or Distribution."
 
INTEREST
 
     Each Convertible Debenture will bear interest at the rate of    % per annum
from the original date of issuance, payable quarterly in arrears on March 31,
June 30, September 30 and December 31 (each, an "Interest Payment Date"),
commencing March 31, 1997, to the person in whose name such Convertible
Debenture is registered, subject to certain exceptions, at the close of business
on the March 15, June 15, September 15 and December 15, as the case may be, next
preceding such Interest Payment Date. In the event the Convertible Debentures
shall not continue to remain in book-entry only form, the Company shall have the
right to select record dates, which shall be more than 14 days but less than 60
days prior to the Interest Payment Date.
 
     The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. The amount of interest payable for
any period shorter than a full quarterly period for which interest is computed
will be computed on the basis of the actual number of days elapsed. In the event
that any date on which interest is payable on the Convertible Debentures is not
a Business Day, then payment of the interest payable on such date will be made
on the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay), except that, if such Business Day
is in the next succeeding calendar year, then such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.
 
INTEREST INCOME AND OPTION TO EXTEND INTEREST PAYMENT PERIODS
 
     The Company shall have the right at any time, and from time to time, during
the term of the Convertible Debentures, to defer payments of interest by
extending the interest payment period for a period not exceeding 20 consecutive
quarters; provided, that no Extension Period may extend beyond the maturity of
the
 
                                       64
<PAGE>   66
 
Convertible Debentures, and at the end of which Extension Period the Company
shall pay all interest then accrued and unpaid (including any Additional
Interest) together with interest thereon compounded quarterly at the rate
specified for the Convertible Debentures to the extent permitted by applicable
law ("Compound Interest"); provided, further, that during any such Extension
Period, (a) the Company shall not declare or pay dividends on, or make any
distributions or liquidation payments with respect to, or redeem, purchase or
acquire any of its capital stock (other than (i) purchases or acquisitions of
shares of Common Stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans or the satisfaction by the Company
of its obligations pursuant to any contract or security requiring the Company to
purchase shares of the Common Stock, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged or (iv) stock
dividends paid by the Company where the dividend stock is the same stock as that
on which the dividend is paid), (b) the Company shall not make any payment of
interest on or principal of (or premium, if any, on) or repay, repurchase or
redeem any debt securities (including guarantees) issued by the Company which
rank pari passu with or junior to the Convertible Debentures and (c) the Company
shall not make any guarantee payments with respect to the foregoing (other than
pursuant to the Guarantee). Prior to the termination of any such Extension
Period, the Company may further extend such Extension Period; provided, that
such Extension Period together with all previous and further extensions thereof
may not exceed 20 consecutive quarters; and provided further that no Extension
Period may extend beyond the maturity date of the Convertible Debentures. Upon
the termination of any Extension Period and the payment of all amounts then due,
the Company may commence a new Extension Period, subject to the above
requirements. No interest shall be due and payable during an Extension Period.
The Company has no current intention of exercising its right to defer payments
of interest by extending the interest payment period on the Convertible
Debentures. If the Institutional Trustee shall be the sole holder of the
Convertible Debentures, the Company shall give the Regular Trustees and the
Institutional Trustee notice of its selection of such Extension Period at least
one Business Day prior to the earlier of (i) the date the distributions on the
Preferred Securities would be payable, if not for such Extension Period or (ii)
the date the Regular Trustees are required to give notice to the NNM (or any
applicable self-regulatory organization) or to holders of the Preferred
Securities of the record date or the date such distribution would be payable if
not for such Extension Period, but in any event not less than one Business Day
prior to such record date. The Regular Trustees shall give notice of the
Company's selection of such Extension Period to the holders of the Preferred
Securities. If the Institutional Trustee shall not be the sole holder of the
Convertible Debentures, the Company shall give the holders of the Convertible
Debentures notice of its selection of such Extension Period at least ten
Business Days prior to the earlier of (i) the next succeeding Interest Payment
Date or (ii) the date upon which the Company is required to give notice to the
NNM (or any applicable self-regulatory organization) or to holders of the
Convertible Debentures on the record or payment date of such related interest
payment.
 
ADDITIONAL INTEREST
 
     If at any time the Trust shall be 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, then, in any
such case, the Company will pay as additional interest ("Additional Interest")
on the Convertible Debentures such additional amounts as shall be required so
that the net amounts received and retained by the Trust after paying any such
taxes, duties, assessments or governmental charges will be not less than the
amounts the Trust would have received had no such taxes, duties, assessments or
governmental charges been imposed.
 
CONVERSION OF THE CONVERTIBLE DEBENTURES
 
The Convertible Debentures will be convertible into Common Stock at the option
of the holders of the Convertible Debentures at any time on or after
               , 1997 (60 days after the date of issue) and prior to 5:00 P.M.
(New York City time) on the Business Day immediately preceding the date of
repayment of such Convertible Debentures, whether at maturity or upon redemption
(either at the option of the Company
 
                                       65
<PAGE>   67
 
or pursuant to a Tax Event), at the initial conversion price set forth on the
cover page of this Prospectus subject to the conversion price adjustments
described under "Description of the Preferred Securities -- Conversion Rights."
The Trust will covenant not to convert Convertible Debentures held by it except
pursuant to a notice of conversion delivered to the Conversion Agent by a holder
of Preferred Securities. Upon surrender of a Preferred Security to the
Conversion Agent for conversion, the Trust will distribute $25 principal amount
of the Convertible Debentures per Preferred Security to the Conversion Agent on
behalf of the holder of the Preferred Securities so converted whereupon the
Conversion Agent will convert such Convertible Debentures to Common Stock on
behalf of such holder. The Company's delivery to the holders of the Convertible
Debentures (through the Conversion Agent) of the fixed number of shares of
Common Stock into which the Convertible Debentures are convertible (together
with the cash payment, if any, in lieu of fractional shares) will be deemed to
satisfy the Company's obligation to pay the principal amount of the Convertible
Debentures so converted, and the accrued and unpaid interest thereon
attributable to the period from the last date to which interest has been paid or
duly provided for; provided, however, that if any Convertible Debenture is
converted after a record date for payment of interest, the interest payable on
the related interest payment date with respect to such Convertible Debenture
shall be paid to the Trust (which will distribute such interest to the holder of
such Preferred Security on the record date) or other holder of Convertible
Debentures, as the case may be, despite such conversion; provided, further that
if any Convertible Debentures are delivered for conversion during an Extension
Period by a holder after receiving a notice of redemption from the Institutional
Trustee, the Company shall be required to pay to the Trust all accrued and
unpaid interest, if any, on such Convertible Debentures through the date of
conversion which amount shall be simultaneously distributed to the holders of
the Preferred Securities in respect of which such Convertible Debentures were
delivered. See "-- Optional Redemption," "Description of the Preferred
Securities -- Conversion Rights" and "-- Mandatory Redemption."
 
CERTAIN COVENANTS
 
In the Indenture, so long as any Convertible Debentures are outstanding, if (i)
there shall have occurred and be continuing any event that with the giving of
notice or the lapse of time or both, would constitute an Indenture Event of
Default, (ii) the Company shall be in default with respect to its payment of any
obligations under the Guarantee, or (iii) the Company has exercised its option
to defer interest payments on the Convertible Debentures by extending the
interest payment period and such period, or any extension thereof, shall be
continuing, then (a) the Company shall not declare or pay dividends on, or make
any distributions or liquidation payments with respect to, or redeem, purchase
or acquire any of its capital stock (other than (i) purchases or acquisitions of
shares of Common Stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans or the satisfaction by the Company
of its obligations pursuant to any contract or security requiring the Company to
purchase shares of the Common Stock, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged or (iv) stock
dividends paid by the Company where the dividend stock is the same stock as that
on which the dividend is paid), (b) the Company shall not make any payment of
interest on or principal of (or premium, if any, on) or repay, repurchase or
redeem any debt securities (including guarantees) issued by the Company which
rank pari passu with or junior to the Convertible Debentures and (c) the Company
shall not make any guarantee payments with respect to the foregoing (other than
pursuant to the Guarantee).
 
     The Company will covenant (i) to directly or indirectly maintain 100%
ownership of the Common Securities of the Trust; provided, however, that any
permitted successor of the Company under the Indenture may succeed to the
Company's ownership of such Common Securities and (ii) to use its reasonable
efforts to cause the Trust (x) to remain a statutory business trust, except in
connection with the distribution of Convertible Debentures to the holders of
Trust Securities in liquidation of the Trust, the redemption of all of the Trust
Securities of the Trust, or certain mergers, consolidations or amalgamation,
each as permitted by the Declaration, and (y) to otherwise continue to be
classified as a grantor trust for United States federal income tax purposes.
 
                                       66
<PAGE>   68
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Indenture provides that the Company will not consolidate with or merge
into any other corporation or convey, transfer or lease its assets substantially
as an entirety unless (a) if the Company is not the survivor, the successor is a
corporation organized under the laws of a State of the United States and
expressly assumes the due and punctual payment of the principal of (and premium,
if any) and interest on all Convertible Debentures issued thereunder and the
performance of every other covenant of the Indenture on the part of the Company
and (b) immediately thereafter no event of default under the Indenture and no
event which, after notice or lapse of time, or both, would become an event of
default under the Indenture, shall have occurred and be continuing. Upon any
such consolidation, merger, conveyance or transfer, the successor corporation
shall succeed to and be substituted for the Company under the Indenture and
thereafter the predecessor corporation shall be relieved of all obligations and
covenants under the Indenture and the Convertible Debentures.
 
INDENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events, which has occurred and is continuing, constitutes an "Indenture Event of
Default" with respect to the Convertible Debentures: (i) failure for 30 days to
pay interest on the Convertible Debentures, including any Additional Interest
and Compound Interest in respect thereof, when due provided that a valid
extension of an interest payment period will not constitute a default in the
payment of interest (including any Additional Interest and Compound Interest)
for this purpose; or (ii) failure to pay principal of or premium, if any, on the
Convertible Debentures when due whether at maturity, upon redemption, by
declaration or otherwise; or (iii) failure to observe or perform any other
covenant contained in the Indenture for 90 days after notice to the Company by
the Indenture Trustee or by the holders of not less than 25% in aggregate
outstanding principal amount of the Convertible Debentures; or (iv) failure by
the Company to deliver shares of Common Stock upon an election by a holder of
Preferred Securities to convert such Preferred Securities; or (v) the
dissolution, winding up or termination of the Trust, except in connection with
the distribution of Convertible Debentures to the holders of Preferred
Securities in liquidation of the Trust, upon the redemption of all outstanding
Preferred Securities in connection with certain mergers, consolidations or
amalgamation permitted by the Declaration; or (vi) certain events of bankruptcy,
insolvency or reorganization of the Company.
 
     The Indenture Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of the Convertible Debentures may declare the
principal of and interest on the Convertible Debentures due and payable
immediately on the occurrence of an Indenture Event of Default; provided,
however, that, after such acceleration, but before a judgment or decree based on
acceleration, the holders of a majority in aggregate principal amount of
outstanding Convertible Debentures may, under certain circumstances, rescind and
annul such acceleration if all Indenture Events of Default, other than the
nonpayment of accelerated principal, have been cured or waived as provided in
the Indenture. For information as to waiver of defaults, see "-- Modifications
and Amendments of the Indenture."
 
     Notwithstanding the foregoing, if an Indenture Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Convertible Debentures on the date
such interest or principal is otherwise payable, the Company acknowledges that,
in such event, a holder of Preferred Securities may institute a Direct Action
for payment on or after the respective due date specified in the Convertible
Debentures. The Company may not amend the Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of all the
holders of Preferred Securities. Notwithstanding any payment made to such holder
of Preferred Securities by the Company in connection with a Direct Action, the
Company shall remain obligated to pay the principal of or interest of the Trust
on the Convertible Debentures held by the Trust or the Institutional Trustee,
and the Company shall be subrogated to the rights of the holder of such
Preferred Securities with respect to payments on the Preferred Securities to the
extent of any payments made by the Company to such holder in any Direct Action.
The holders of Preferred Securities will not be able to exercise directly any
other remedy available to the holders of the Convertible Debentures.
 
     The Holders of not less than a majority in principal amount of the
outstanding Convertible Debentures may on behalf of the holders of all the
Convertible Debentures waive any past defaults except (a) a default in
 
                                       67
<PAGE>   69
 
payment of the principal of (or premium, if any) or interest (including
Additional Interest and Compound Interest) on any Convertible Debentures and (b)
a default in respect of a covenant or provision of the Indenture which cannot be
amended or modified without the consent of the holder of each Convertible
Debenture; provided, however, that if the Convertible Debentures are held by the
Trust or a trustee of such Trust, such waiver or modification to such waiver
shall not be effective until the holders of a majority in liquidation amount of
Trust Securities shall have consented to such waiver or modification to such
waiver; provided, further, that if the consent of the holder of each outstanding
Convertible Debenture is required, such waiver shall not be effective until each
holder of the Trust Securities shall have consented to such waiver.
 
     A default under any other indebtedness of the Company would not constitute
an Indenture Event of Default.
 
     Subject to the provisions of the Indenture relating to the duties of the
Indenture Trustee, in case an Indenture Event of Default shall occur and be
continuing, 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
holders of Convertible Debentures, unless such holders shall have offered to the
Indenture Trustee reasonable indemnity. Subject to such provisions for the
indemnification of the Indenture Trustee, the holders of a majority in aggregate
principal amount of the Convertible Debentures then outstanding 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 such series.
 
     No holder of any Convertible Debenture will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
(i) such holder shall have previously given to the Indenture Trustee written
notice of a continuing Indenture Event of Default, (ii) if the Trust is not the
sole holder of Convertible Debentures, the holders of at least 25% in aggregate
principal amount of the Convertible Debentures then outstanding shall also have
made a written request, (iii) such holder has offered reasonable indemnity to
the Indenture Trustee to institute such proceeding as Indenture Trustee, (iv)
the Indenture Trustee shall have failed to institute such proceeding within 60
days of such notice, and (v) the Indenture Trustee shall not have received from
the holders of a majority in aggregate principal amount of the outstanding
Convertible Debentures a direction inconsistent with such request. However, such
limitations do not apply to a suit instituted by a holder of a Convertible
Debenture for enforcement of payment of the principal of or interest on such
Convertible Debenture on or after the respective due dates expressed in such
Convertible Debenture.
 
     The Company is required to file annually with the Indenture Trustee and the
Institutional Trustee a certificate as to whether or not the Company is in
compliance with all the conditions and covenants under the Indenture.
 
MODIFICATIONS AND AMENDMENTS OF THE INDENTURE
 
     The Indenture contains provisions permitting the Company and the Indenture
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the outstanding Convertible Debentures, to modify
the Indenture or the rights of the holders of Convertible Debentures; provided,
however, that no such modification may, without the consent of the holder of
each outstanding Convertible Debenture affected thereby, (i) extend the stated
maturity of the Convertible Debentures or reduce the principal amount thereof,
or reduce the rate or extend the time of payment of interest thereon, or
adversely affect the right to convert Convertible Debentures or the
subordination provisions of the Indenture, or (ii) reduce the percentage in
aggregate principal amount of outstanding Convertible Debentures, the holders of
which are required to consent to any such supplemental indenture.
 
     In addition, the Company and the Indenture Trustee may execute, without the
consent of any holder of Convertible Debentures, any supplemental indenture to
cure any ambiguities, comply with the Trust Indenture Act and for certain other
customary purposes.
 
BOOK-ENTRY AND SETTLEMENT
 
     If distributed to holders of Preferred Securities in connection with the
involuntary or voluntary dissolution, winding-up or liquidation of the Trust as
a result of the occurrence of a Special Event, the
 
                                       68
<PAGE>   70
 
Convertible Debentures will be issued in the form of one or more global
certificates (each a "Global Security") registered in the name of the depositary
or its nominee. Except under the limited circumstances described below,
Convertible Debentures represented by a Global Security will not be exchangeable
for, and will not otherwise be issuable as, Convertible Debentures in definitive
form. The Global Securities described above may not be transferred except by the
depositary to a nominee of the depositary or by a nominee of the depositary to
the depositary or another nominee of the depositary or to a successor depositary
or its nominee.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.
 
     Except as provided below, owners of beneficial interests in such a Global
Security will not be entitled to receive physical delivery of Convertible
Debentures in definitive form and will not be considered the holders thereof for
any purpose under the Indenture, and no Global Security representing Convertible
Debentures shall be exchangeable, except for another Global Security of like
denomination and tenor to be registered in the name of the depositary or its
nominee or to a successor depositary or its nominee. Accordingly, each
beneficial owner must rely on the procedures of the depositary or if such person
is not a Participant, on the procedures of the Participant through which such
person owns its interest to exercise any rights of a holder under the Indenture.
 
THE DEPOSITARY
 
     If Convertible Debentures are distributed to holders of Preferred
Securities in liquidation of such holders' interest in the Trust, DTC will act
as securities depositary for the Convertible Debentures. For a description of
DTC and the specific terms of the depositary arrangements, see "Description of
the Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company." As of the date of this Prospectus, the description therein of DTC's
book-entry system and DTC's practices as they relate to purchases, transfers,
notices and payments with respect to the Preferred Securities apply in all
material respects to any debt obligations represented by one or more Global
Securities held by DTC. The Company may appoint a successor to DTC or any
successor depositary in the event DTC or such successor depositary is unable or
unwilling to continue as a depositary for the Global Securities.
 
     None of the Company, the Trust, the Indenture Trustee, any paying agent and
any other agent of the Company or the Indenture Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
for such Convertible Debentures or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
DISCONTINUANCE OF THE DEPOSITARY'S SERVICES
 
     A Global Security shall be exchangeable for Convertible Debentures
registered in the names of persons other than the depositary or its nominee only
if (i) the depositary notifies the Company that it is unwilling or unable to
continue as a depositary for such Global Security and no successor depositary
shall have been appointed, (ii) the depositary, at any time, ceases to be a
clearing agency registered under the Exchange Act at which time the depositary
is required to be so registered to act as such depositary and no successor
depositary shall have been appointed, (iii) the Company, in its sole discretion,
determines that such Global Security shall be so exchangeable or (iv) there
shall have occurred an Indenture Event of Default with respect to such
Convertible Debentures. Any Global Security that is exchangeable pursuant to the
preceding sentence shall be exchangeable for Convertible Debentures registered
in such names as the depositary shall direct. It is expected that such
instructions will be based upon directions received by the depositary from its
Participants with respect to ownership of beneficial interests in such Global
Security.
 
GOVERNING LAW
 
     The Indenture and the Convertible Debentures will be governed by, and
construed in accordance with, the internal laws of the State of New York.

INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
     The Indenture Trustee, prior to default, undertakes to perform only such
duties as are specifically set forth in the Indenture and, after default, shall
exercise the same degree of care as a prudent individual would exercise in the
conduct of his or her own affairs. Subject to such provision, the Indenture
Trustee is under no obligation to exercise any of the powers vested in it by the
Indenture at the request of any holder of Convertible Debentures, unless offered
reasonable indemnity by such holder against the costs, expenses and liabilities
which might be incurred thereby. The Indenture Trustee is not required to expend
or risk its own funds or otherwise incur personal financial liability in the
performance of its duties if the Indenture Trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.
 
MISCELLANEOUS
 
     The Indenture will provide that the Company will pay all fees and expenses
related to (i) the offering of the Trust Securities and the Convertible
Debentures, (ii) the organization, maintenance and dissolution of the Trust,
(iii) the retention of the Trustees and (iv) the enforcement by the
Institutional Trustee of the rights of the holders of the Preferred Securities.

                          DESCRIPTION OF THE GUARANTEE
 
     Set forth below is a summary of information concerning the Guarantee that
will be executed and delivered by the Company for the benefit of the holders of
Preferred Securities. The summary does not purport to be complete and is subject
in all respects to the provisions of, and is qualified in its entirety by
reference to, the Guarantee, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. The Guarantee
incorporates by reference the terms of the Trust Indenture Act. The Guarantee
will be qualified under the Trust Indenture Act. Bankers Trust Company, as the
Guarantee Trustee, will hold the Guarantee for the benefit of the holders of the
Preferred Securities.
 
GENERAL
 
     Pursuant to and to the extent set forth in the Guarantee, the Company will
irrevocably and unconditionally agree to pay in full to the holders of the
Preferred Securities (except to the extent paid by such Trust), as and when due,
regardless of any defense, right of set off or counterclaim which the Trust may
have or assert, the following payments (the "Guarantee Payments"), without
duplication: (i) any accrued and unpaid distributions that are required to be
paid on the Preferred Securities, to the extent the Trust has funds available
therefor, (ii) the Redemption Price with respect to any Preferred Securities
called for redemption by the Trust, to the extent the Trust has funds available
therefor and (iii) upon a voluntary or involuntary dissolution, winding-up or
termination of the Trust (other than in connection with the distribution of
Convertible Debentures to the holders of Preferred Securities or the redemption
of all the Preferred Securities), the lesser of (a) the aggregate of the
liquidation amount and all accrued and unpaid distributions on the Preferred
Securities to the date of payment and (b) the amount of assets of the Trust
remaining available for distribution to holders of Preferred Securities upon the
liquidation of the Trust. The Company's obligation to make a Guarantee Payment
may be satisfied by direct payment of the required amount by the Company to the
holders of Preferred Securities or by causing the Trust to pay such amounts to
such holders.
 
     The Guarantee will be a guarantee on a subordinated basis with respect to
the Preferred Securities from the time of issuance of such Preferred Securities
but will not apply to any payment of distributions or Redemption Price, or to
payments upon the dissolution, winding-up or termination of the Trust, except to
the extent the Trust shall have funds available therefor. If the Company does
not make interest payments on the Convertible Debentures, the Trust will not pay
distributions on the Preferred Securities and will not have funds available
therefor. See "Description of the Convertible Debentures." The Guarantee, when
taken together with the Company's obligations under the Convertible Debentures,
the Indenture and the Declaration, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Trust Securities), will provide a full and unconditional guarantee on a
subordinated basis by the Company of payments due on the Preferred Securities.
 
CERTAIN COVENANTS OF THE COMPANY
 
     In the Guarantee, the Company will covenant that so long as any Preferred
Securities remain outstanding, if (i) the Company has exercised its option to
defer interest payments on the Convertible Debentures by extending the interest
payment period and such extension shall be continuing, (ii) the Company shall be
in default with respect to its payment or other obligations under the Guarantee
or (iii) there shall have occurred and be continuing any event that, with the
giving of notice or the lapse of time or both, would constitute an Indenture
Event of Default, then the Company has agreed (a) not to declare or pay
dividends on, or make a distribution with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
(other than (i) purchases or acquisitions of shares of Common Stock in
connection with the satisfaction by the Company of its obligations under any
employee benefit plans or the satisfaction by the Company of its obligations
pursuant to any contract or security requiring the Company to purchase shares of
Common Stock, (ii) as a result of a reclassification of the Company's capital
stock or the exchange or conversion of one class or series of the Company's
capital stock for another class or series of the Company's capital stock or
(iii) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged), (b) not to make any payment of
interest, principal or premium, if
 
                                       71
<PAGE>   73
 
any, on or repay, repurchase or redeem any debt securities of the Company
(including guarantees) that rank pari passu with or junior to the Convertible
Debentures and (c) not to make any guarantee payments with respect to the
foregoing (other than pursuant to the Guarantee).
 
     As part of the Guarantee, the Company will agree that it will honor all
obligations described therein relating to the conversion of the Preferred
Securities into Common Stock as described in "Description of the Preferred
Securities -- Conversion Rights."
 
MODIFICATION OF THE GUARANTEE; ASSIGNMENT
 
     Except with respect to any changes that do not materially adversely affect
the rights of holders of Preferred Securities (in which case no vote will be
required), the Guarantee may be amended only with the prior approval of the
holders of at least a majority in aggregate liquidation amount of all the
outstanding Preferred Securities. All guarantees and agreements contained in the
Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of the Company and shall inure to the benefit of the holders of
the Preferred Securities then outstanding. Except in connection with any
permitted merger or consolidation of the Company with or into another entity or
any permitted sale, transfer or lease of the Company's assets to another entity
as described under "Description of the Convertible Debentures -- Consolidation,
Merger and Sale of Assets," the Company may not assign its rights or delegate
its obligations under the Guarantee without the prior approval of the holders of
at least a majority of the aggregate stated liquidation amount of the Preferred
Securities then outstanding. All guarantees and agreements contained in the
Guarantee shall bind the permitted successors, assigns and transferees of the
Company and shall inure to the benefit of the holders of the Preferred
Securities then outstanding.
 
EVENTS OF DEFAULT
 
     An Event of Default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder. The
holders of a majority in aggregate liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of the
Guarantee or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under the Guarantee. If the Guarantee Trustee fails to enforce
the Guarantee Trustee's rights under the Guarantee, any holder of related
Preferred Securities may directly institute a legal proceeding against the
Company to enforce the Guarantee Trustee's rights under the Guarantee without
first instituting a legal proceeding against the Trust, the Guarantee Trustee or
any other person or entity. A holder of Preferred Securities may also directly
institute a legal proceeding against the Company to enforce such holder's right
to receive payment under the Guarantee without first (i) directing the Guarantee
Trustee to enforce the terms of the Guarantee or (ii) instituting a legal
proceeding against the Trust or any other person or entity.
 
     The Company will be required to provide annually to the Guarantee Trustee a
statement as to the performance by the Company of certain of its obligations
under the Guarantee and as to any default in such performance.
 
INFORMATION CONCERNING THE INSTITUTIONAL TRUSTEE
 
     The Institutional Trustee, prior to the occurrence of a default with
respect to the Trust Securities, undertakes to perform only such duties as are
specifically set forth in the Declaration and, after default, shall exercise the
same degree of care as a prudent individual would exercise in the conduct of his
own affairs. Subject to such provisions, the Institutional Trustee is under no
obligation to exercise any of the powers vested in it by the Declaration at the
request of any holder of Preferred Securities, unless offered reasonable
indemnity by such holder against the costs, expenses and liabilities which might
be incurred thereby. The holders of Preferred Securities will not be required to
offer such indemnity in the event such holders, by exercising their voting
rights, direct the Institutional Trustee to take any action following a
Declaration Event of Default.
 
                                       72
<PAGE>   74
 
TERMINATION OF THE GUARANTEE
 
     The Guarantee will terminate as to the Preferred Securities upon (i) full
payment of the Redemption Price of all Preferred Securities; or (ii)
distribution of the Convertible Debentures held by the Trust to the holders of
the Preferred Securities; or (iii) liquidation of the Trust; or (iv)
distribution of Common Stock to such holder in respect of conversion of such
holder's Preferred Securities into Common Stock. The Guarantee also will
terminate completely upon full payment of the amounts payable in accordance with
the Declaration. The Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of Preferred
Securities must restore payment of any sum paid under such Preferred Securities
or the Guarantee.
 
STATUS OF THE GUARANTEE
 
     The Guarantee will constitute an unsecured obligation of the Company and
will rank (i) subordinate and junior to all other liabilities of the Company
except any liabilities that may be pari passu expressly by their terms, (ii)
pari passu with the most senior preferred or preference stock, if any, issued
from time to time by the Company and with any guarantee now or hereafter entered
into by the Company in respect of any preferred or preference stock or preferred
securities of any affiliate of the Company and (iii) senior to the Common Stock.
The terms of the Preferred Securities provide that each holder of Preferred
Securities by acceptance thereof agrees to the subordination provisions and
other terms of the Guarantee.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may directly institute a legal proceeding against
the Company to enforce its rights under a Guarantee without instituting a legal
proceeding against any other person or entity).
 
GOVERNING LAW
 
     The Guarantee will be governed by, and construed in accordance with, the
internal laws of the State of New York.

                        EFFECT OF OBLIGATIONS UNDER THE
                    CONVERTIBLE DEBENTURES AND THE GUARANTEE
 
     As set forth in the Declaration, the sole purpose of the Trust is to issue
the Trust Securities evidencing undivided beneficial interests in the assets of
the Trust, and to invest the proceeds from such issuance and sale in the
Convertible Debentures.
 
     As long as payments of interest and other payments are made when due on the
Convertible Debentures, such payments will be sufficient to cover distributions
and payments due on the Trust Securities because of the following factors: (i)
the aggregate principal amount of Convertible Debentures will be equal to the
sum of the aggregate stated liquidation amount of the Trust Securities; (ii) the
interest rate and the interest and other payment dates on the Convertible
Debentures will match the distribution rate and distribution and other payment
dates for the Preferred Securities; (iii) pursuant to the Indenture, the Company
shall pay all, and the Trust shall not be obligated to pay, directly or
indirectly, any, costs, expenses, debts and liabilities of the Trust other than
with respect to the Trust Securities; and (iv) the Declaration further provides
that the Trustees will not cause or permit the Trust to, among other things,
engage in any activity that is not consistent with the purposes of the Trust.
 
     Payments of distributions (to the extent funds therefor are available) and
other payments due on the Preferred Securities (to the extent funds therefor are
available) are guaranteed by the Company as and to the extent set forth under
"Description of the Guarantee." If the Company does not make interest payments
on the Convertible Debentures purchased by the Trust, it is expected that the
Trust will not have sufficient funds to pay distributions on the Preferred
Securities. The Guarantee is a guarantee on a subordinated basis with respect to
the Preferred Securities from the time of its issuance but does not apply to any
payment of distributions unless and until the Trust has sufficient funds for the
payment of such distributions.
 
     The Guarantee covers the payment of distributions and other payments on the
Preferred Securities only if and to the extent that the Company has made a
payment of interest or principal on the Convertible Debentures held by the Trust
as its sole asset. The Guarantee, when taken together with the Company's
obligations under the Convertible Debentures and the Indenture and its
obligations under the Declaration, including its obligations to pay costs,
expenses, debts and liabilities of the Trust (other than with respect to the
Trust Securities), will provide a full and unconditional guarantee of amounts on
the Preferred Securities.
 
     If the Company fails to make interest or other payments on the Convertible
Debentures when due (taking account of any Extension Period), the Declaration
provides a mechanism whereby the holders of the Preferred Securities, using the
procedures described in "Description of the Preferred Securities -- Voting
Rights" and "-- Book-Entry Only Issuance -- The Depository Trust Company," may
direct the Institutional Trustee to enforce its rights under the Convertible
Debentures. If the Institutional Trustee fails to enforce its rights under the
Convertible Debentures, to the fullest extent permitted by law, any holder of
Preferred Securities may directly institute a legal proceeding against the
Company to enforce the Institutional Trustee's rights under the Convertible
Debentures without first instituting any legal proceeding against the
Institutional Trustee or any other person or entity. If a Declaration Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on the Convertible
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities may institute a Direct Action for payment on or after the respective
due date specified in the Convertible Debentures. In connection with such Direct
Action, the Company will be subrogated to the rights of such holder of Preferred
Securities under the Declaration to the extent of any payment made by the
Company to such holder of Preferred Securities in such Direct Action. The
Company, under the Guarantee, acknowledges that the Guarantee Trustee shall
enforce the Guarantee on behalf of the holders of the Preferred Securities. If
the Company fails to make payments under the Guarantee, the Guarantee provides a
mechanism whereby the holders of the Preferred Securities may direct the
Guarantee Trustee to enforce its rights thereunder. If the Guarantee Trustee
fails to enforce the Guarantee, any holder of Preferred Securities may directly
institute a legal proceeding against the Company to enforce the Guarantee
Trustee's rights under the Guarantee without first instituting a legal
proceeding against the Trust, the Guarantee Trustee, or any other person or
entity.
 
     The Company and the Trust believe that the above mechanisms and
obligations, taken together, are equivalent to a full and unconditional
guarantee by the Company of payments due on the Preferred Securities. See
"Description of Guarantee -- General."

                     UNITED STATES FEDERAL INCOME TAXATION
 
GENERAL
 
     The following is a summary of certain of the material United States federal
income tax consequences of the purchase, ownership, disposition and conversion
of Preferred Securities. Unless otherwise stated, this summary deals only with
Preferred Securities held as capital assets by holders who purchase the
Preferred Securities upon original issuance. This summary addresses the United
States federal income tax considerations to holders of Preferred Securities who
are citizens or residents of the United States, corporations, partnerships or
other entities created or organized in or under the laws of the United States or
any political subdivision thereof or therein, or estates or trusts the income of
which is subject to United States federal income taxation regardless of its
source or other holders who are otherwise subject to United States federal
income taxation on a net income basis with respect to Preferred Securities
("U.S. Holders") and does not address the tax consequences to holders of
Preferred Securities who are not U.S. Holders. This summary does not deal with
special classes of holders such as banks, thrift institutions, real estate
investment trusts, regulated investment companies, insurance companies, dealers
in securities or currencies, tax-exempt investors, or persons that will hold the
Preferred Securities as part of a straddle, hedge or conversion transaction, or
as other than a capital asset. This summary also does not address tax
consequences to persons that have a functional currency other than the U.S.
Dollar or the tax consequences to shareholders, partners or beneficiaries of a
holder of Preferred Securities. Further, it does not include any description of
any alternative minimum tax consequences or the tax laws of any state or local
government or of any foreign government that may be applicable to the Preferred
Securities. This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations thereunder and administrative and
judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis.
 
CLASSIFICATION OF THE CONVERTIBLE DEBENTURES
 
     The Company intends to take the position that the Convertible Debentures
will be classified for United States federal income tax purposes as indebtedness
of the Company under current law, and, by acceptance of a Preferred Security,
each holder covenants to treat the Convertible Debentures as indebtedness and
the Preferred Securities as evidence of an indirect beneficial ownership
interest in the Convertible Debentures. No assurance can be given, however, that
such position of the Company will not be challenged by the Internal Revenue
Service or, if challenged, that such a challenge would not be successful. The
remainder of this discussion assumes that the Convertible Debentures will be
classified as indebtedness of the Company for United States federal income tax
purposes.
 
CLASSIFICATION OF THE TRUST
 
     In connection with the issuance of the Preferred Securities, Katten Muchin
& Zavis, tax counsel to the Company and the Trust, will render its opinion
generally to the effect that, under then current law and assuming full
compliance with the terms of the Declaration and the Indenture (and certain
other documents), and based on certain facts and assumptions contained in such
opinion, the Trust will be classified for United States federal income tax
purposes as a grantor trust and not as an association taxable as a corporation.
Accordingly, for United States federal income tax purposes, each holder of
Preferred Securities generally will be considered the owner of an undivided
interest in the Convertible Debentures, and each holder will be required to
include in its gross income any OID accrued with respect to its allocable share
of those Convertible Debentures.
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
     Because the Company has the option, under the terms of the Convertible
Debentures, to defer payments of interest by extending interest payment periods
for up to 20 quarters, all of the stated interest payments on the Convertible
Debentures will be treated as "original issue discount." Holders of debt
instruments issued with OID must include that discount in income on an economic
accrual basis before the receipt of cash attributable to the interest,
regardless of their method of tax accounting. Generally, all of a holder's
taxable interest income with respect to the Convertible Debentures will be
accounted for as OID, and actual distributions of stated interest will not be
separately reported as taxable income. The amount of OID that
 
                                       75
<PAGE>   77
 
accrues in any month will approximately equal the amount of the interest that
accrues on the Convertible Debentures in that month at the stated interest rate.
In the event that the interest payment period is extended, holders will continue
to accrue OID approximately equal to the amount of the interest payment due at
the end of the extended interest payment period on an economic accrual basis
over the length of the extended interest period.
 
RECEIPT OF CONVERTIBLE DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST
 
     Under certain circumstances, as described under the caption "Description of
the Preferred Securities -- Special Event Redemption or Distribution," the
Convertible Debentures may be distributed to holders in exchange for the
Preferred Securities and in liquidation of the Trust. Under current law, such a
distribution, for United States federal income tax purposes, would be treated as
a non-taxable event to each holder, and each holder would receive an aggregate
tax basis in the Convertible Debentures equal to such holder's aggregate tax
basis in its Preferred Securities. A holder's holding period in the Convertible
Debentures so received in liquidation of the Trust would include the period
during which the Preferred Securities were held by such holder.
 
     Under certain circumstances described under "Description of the Preferred
Securities -- Special Event Redemption or Distribution," the Convertible
Debentures may be redeemed for cash and the proceeds of such redemption
distributed to holders in redemption of their Preferred Securities. Under
current law, such a redemption of the Convertible Debentures would, for United
States federal income tax purposes, constitute a taxable disposition of the
redeemed Preferred Securities, and a holder could recognize gain or loss as if
it sold such redeemed Preferred Securities for cash. See "-- Sales of Preferred
Securities."
 
SALES OF PREFERRED SECURITIES
 
     A holder that sells Preferred Securities will recognize gain or loss equal
to the difference between its adjusted tax basis in the Preferred Securities and
the amount realized on the sale of such Preferred Securities. A holder's
adjusted tax basis in the Preferred Securities generally will be its initial
purchase price increased by OID previously includible in such holder's gross
income to the date of disposition and decreased by payments received on the
Preferred Securities. Such gain or loss generally will be a capital gain or loss
and generally will be a long-term capital gain or loss if the Preferred
Securities have been held for more than one year.
 
     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
Convertible Debentures. A holder who disposes of his Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest on the Convertible Debentures through the
date of disposition in income as ordinary income and to add such amount to his
adjusted tax basis in his pro rata share of the underlying Convertible
Debentures deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis (which will include, in the form of OID, all accrued
but unpaid interest) a holder 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.
 
     Because income on the Preferred Securities will constitute interest (in the
form of OID) for federal income tax purposes, corporate holders of Preferred
Securities will not be entitled to a dividends received deduction with respect
to any income recognized with respect to the Preferred Securities.
 
CONVERSION OF PREFERRED SECURITIES
 
     A holder generally will not recognize income, gain or loss upon the
conversion, through the Conversion Agent, of its Preferred Securities into
Common Stock. A holder will, however, recognize gain upon the receipt of cash in
lieu of a fractional share of Common Stock equal to the amount of cash received
less the holder's tax basis in such fractional share. A holder's tax basis in
the Common Stock received upon exchange and conversion should generally be equal
to the holder's tax basis in the Preferred Securities delivered to the
Conversion Agent for exchange less the basis allocated to any fractional share
for which cash is received, and a holder's holding period in the Common Stock
received upon exchange and conversion should generally begin on the date the
holder acquired the Preferred Securities delivered to the Conversion Agent for
exchange.
 
                                       76
<PAGE>   78
 
ADJUSTMENT OF CONVERSION PRICE
 
     Treasury Regulations promulgated under Section 305 of the Code would treat
holders of Preferred Securities as having received a constructive distribution
from the Company in the event the conversion ratio of the Convertible Debentures
were adjusted if (i) as a result of such adjustment, the proportionate interest
(measured by the quantum of Common Stock into or for which the Convertible
Debentures are convertible or exchangeable) of the holders of the Preferred
Securities in the assets or earnings and profits of the Company were increased,
and (ii) the adjustment was not made pursuant to a bona fide, reasonable
anti-dilution formula. An adjustment in the conversion ratio would not be
considered made pursuant to such a formula if the adjustment was made to
compensate for certain taxable distributions with respect to the Common Stock.
Thus, under certain circumstances, a reduction in the conversion price for the
holders may result in deemed dividend income to holders to the extent of the
current or accumulated earnings and profits of the Company. Holders of the
Preferred Securities would be required to include their allocable share of such
deemed dividend income in gross income but would not receive any cash related
thereto.
 
PROPOSED TAX LEGISLATION
 
     On March 19, 1996, the U.S. Treasury Department proposed certain tax law
changes (the "Proposed Legislation") that would, among other things, generally
deny corporate issuers a deduction for interest in respect of certain debt
obligations with a maximum term of more than 20 years, that are not shown as
indebtedness on the consolidated balance sheet of the issuer. The Convertible
Debentures have a maximum term of 20 years, and therefore would not be adversely
affected by passage of the Proposed Legislation, even if the Proposed
Legislation has a retroactive effective date. However, there can be no assurance
that any Proposed Legislation, if enacted, would not apply to debt obligations
with a term of 20 or fewer years, including the Convertible Debentures.
 
     On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr.
and House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that the Proposed Legislation,
if adopted by either of the tax-writing committees of Congress, would have an
effective date that is no earlier than the date of "appropriate Congressional
action." Based upon the Joint Statement, it is expected that if the Proposed
Legislation were to be enacted, such legislation would not apply to the
Convertible Debentures because they will be issued prior to the date of any
"appropriate Congressional action." There can be no assurance, however, that any
proposed legislation enacted after the date hereof will not otherwise adversely
affect the ability of the Company to deduct the interest payable on the
Convertible Debentures. Accordingly, there can be no assurance that a Tax Event
will not occur. See "Description of the Preferred Securities -- Special Event
Redemption or Distribution."
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Generally, income on the Preferred Securities will be reported to holders
on Forms 1099, which forms should be mailed to holders of Preferred Securities
by January 31 following each calendar year. Payments made on, and proceeds from
the sale of, the Preferred Securities may be subject to a "backup" withholding
tax of 31% unless the holder complies with certain identification requirements.
Any withheld amounts will be allowed as a credit against the holder's United
States federal income tax, provided the required information is provided to the
Internal Revenue Service on a timely basis.
 
     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE
PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN
AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL
OR OTHER TAX LAWS.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 25,000,000 shares
of Common Stock, $.50 par value, and 1,000,000 shares of Preferred Stock, $1.00
par value ("Preferred Stock").
 
COMMON STOCK
 
     Subject to preferences that may be applicable to any outstanding Preferred
Stock, holders of Common Stock are entitled to (a) receive ratably such
dividends as may be declared by the Board of Directors out of funds legally
available therefor, (b) cast one vote per share on all matters to be voted upon
by the stockholders, and (c) in the event of a liquidation, dissolution or
winding up of the Company, share ratably in all assets remaining after payment
of the Company's liabilities and the liquidation preference of any outstanding
Preferred Stock. Holders of Common Stock have no cumulative voting rights or
preemptive rights nor any rights to convert their Common Stock into any other
securities, and there are no redemption provisions with respect to such shares.
All of the outstanding shares of Common Stock are, and the Shares issuable upon
conversion of the Preferred Securities will be, fully paid and non-assessable.
The rights, preferences and privileges of holders of Common Stock are subject
to, and may be adversely affected by, the rights of the holders of shares of
Preferred Stock currently outstanding, described below, and of any series of
Preferred Stock which the Company may designate and issue in the future.
Additional shares of Common Stock may be issued without stockholder approval.
Each share of Common Stock also represents a preferred stock purchase right, as
described below.
 
PREFERRED STOCK
 
The Company has an authorized class of undesignated Preferred Stock consisting
of 1,000,000 shares. The Company's Board of Directors has authority, without any
further vote or action by the stockholders, to provide for the issuance of the
shares of Preferred Stock in series, to establish from time to time the number
of shares to be included in each such series and to fix the designations,
preferences and relative, participating, optional or other special rights, and
qualifications or restrictions of the shares of each such series and to
determine the voting powers, if any, of such shares. The issuance of Preferred
Stock can, among other things, (a) adversely affect the rights of existing
stockholders and the amount of earnings and assets available for distribution to
holders of Common Stock, (b) delay, defer or prevent a change in control of the
Company, and (c) make the removal of the present management of the Company more
difficult. As of December 11, 1996, no shares of Preferred Stock were
outstanding.
 
DELAWARE LAW AND CERTAIN CORPORATE PROVISIONS
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law. In general, this statute prohibits a publicly held
Delaware corporation from engaging, under certain circumstances, in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person becomes an interested
stockholder, unless either (a) prior to the date at which the stockholder became
an interested stockholder, the Board of Directors approved either the business
combination or the transaction in which the person becomes an interested
stockholder, (b) the stockholder acquires more than 85% of the outstanding
voting stock of the corporation (excluding shares held by directors who are
officers or held in certain employee stock plans) upon consummation of the
transaction in which the stockholder becomes an interested stockholder or (c)
the business combination is approved by the Board of Directors and by two-thirds
of the outstanding voting stock of the corporation (excluding shares held by the
interested stockholder) at a meeting of stockholders (and not by written
consent) held on or subsequent to the date of the business combination. An
"interested stockholder" is a person who, together with affiliates and
associates, owns (or at any time within the prior three years did own) 15% or
more of the corporation's voting stock. Section 203 defines a "business
combination" to include, without limitation, mergers, consolidations, stock
sales and asset based transactions and other transactions resulting in a
financial benefit to the interested stockholder.

     The Company's Restated Certificate of Incorporation (the "Certificate") and
By-laws contain a number of provisions relating to corporate governance and to
the rights of stockholders. Certain of these provisions may be deemed to have a
potential "anti-takeover" effect in that such provisions may delay, defer or
prevent a change of control of the Company. These provisions include (a) the
classification of the Board of Directors into three classes, such classes
serving for staggered three year terms; (b) restrictions on the removal of
directors; (c) a requirement that special meetings of stockholders may be called
only by the Board of Directors or by unanimous written stockholder consent and
that stockholder action may be taken only at stockholder meetings or by
unanimous written stockholder consent; (d) the authority of the Board to issue
series of Preferred Stock with such voting rights and other powers as the Board
of Directors may determine without further stockholder approval; (e) a
requirement for certain business combinations of (i) approval by the affirmative
vote of at least 66 2/3% of the voting power of the then outstanding capital
stock of the Company, (ii) approval by a majority of disinterested directors and
(iii) fair consideration to the stockholders; (f) a requirement that the vote of
greater than 66 2/3% of the voting power of the then outstanding capital stock
of the Company is required to amend, alter, repeal provisions, or adopt
inconsistent provisions, of the Certificate relating to (i) the classification
of the Board, (ii) the removal of directors, (iii) the inability of stockholders
to call special meetings and to take action outside of a special meeting other
than by unanimous written consent, and (iv) the stockholder vote and fair price
required for certain business combinations.
 
     In December, 1988, the Company initially designated 40,878 shares of
Preferred Stock for possible future issuance pursuant to the terms of a
Shareholder Rights Plan (the "Rights Plan"). In December 1988, pursuant to the
Rights Plan, the Company issued a dividend of one preferred stock purchase right
on each outstanding share of Common Stock. Each right entitles the holder, upon
the occurrence of certain events (such as an acquisition, or announcement of
intent to acquire, by certain persons or groups of 15% or more of the Company's
Common Stock), to purchase one one-hundredth of a share of a new series of
preferred stock for $75. If a person, entity or group becomes the beneficial
owner of 15% or more of the Company's Common Stock (other than pursuant to
certain limited exceptions), then each holder of a right, other than the 15%
holder, will be entitled to buy the number of shares of Common Stock having a
market value of twice the then exercise price of each right. Furthermore, if the
Company is involved in a merger or other business combination at any time after
the rights become exercisable, the rights will entitle the holder to buy the
number of shares of common stock of the acquiring company having a market value
of twice the then current exercise price of each right. Alternatively, if a 15%
or more shareholder acquires the Company by means of a reverse merger in which
the Company and its stock survives, or engages in self-dealing transactions with
the Company, or if any person acquires 50% or more of the Company's Common
Stock, then each right not owned by a 15% or more shareholder will become
exercisable for the number of shares of Common Stock of the Company having a
market value of twice the then current exercise price of each right. The rights,
which do not have voting rights, expire in December 1998 and may be redeemed by
the Company at a price of $.01 per right at any time prior to their expiration
or the time they become exercisable. The above shareholder rights may be deemed
to have a potential "anti-takeover" effect in that such rights may delay, defer
or prevent a change in control of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Company's Common Stock is Harris
Trust and Savings Bank, Chicago, Illinois.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
CREDIT FACILITY
 
     In July 1995, the Company entered into a credit facility (the "Credit
Facility") among the Company, certain of its subsidiaries, Comerica Bank, as
agent, and the other lenders named therein. The Credit Facility consists of a
$135 million multicurrency revolving loan facility for the Company and certain
of its wholly-owned domestic and foreign subsidiaries, including a $5 million
swing line facility and a $17 million letter of credit facility. The Credit
Facility has an initial term of five years, with annual one year extensions of
the revolving credit portion of the facility available in the lenders'
discretion.
 
     At any time within three years after closing of the Credit Facility, the
Company may convert up to $70 million of revolving loans under the Credit
Facility to term loans in minimum amounts of $15 million and with maturities not
exceeding seven years from the closing of the Credit Facility.
 
     Borrowings under the Credit Facility bear interest at a per annum rate
equal to the agent's base rate or the prevailing interbank offered rate in the
applicable offshore currency market, plus an additional margin ranging from 0.5%
to 1.75% based on certain financial ratios of the Company. The annual letter of
credit fee ranges from 0.5% to 1.5% based on the same financial ratios. The
Company may upon notice convert the interest rate applicable to any term loan
for its remaining term from a floating rate to a fixed rate option, to be
determined at the time of such conversion, based on the lenders' funding rate in
the interbank swap market. The Company is also required to pay a quarterly
unused facility fee.
 
     The Credit Facility is secured by first liens on the inventory, accounts
receivable and certain intangibles (excluding intellectual property) of the
Company and certain of its wholly-owned domestic subsidiaries and by a pledge of
100% of the stock of wholly-owned domestic subsidiaries, and up to 65% of the
stock of wholly-owned foreign subsidiaries. Collateral for the Credit Facility
secures the 2004 Notes on an equal and ratable basis. The Company and its
wholly-owned domestic subsidiaries guarantee payment of domestic and foreign
borrowings under the Credit Facility and the Company's wholly-owned foreign
subsidiaries guarantee payment of foreign borrowings under the Credit Facility.
 
     The Credit Facility contains customary representations and warranties and
events of default and requires compliance with certain covenants by the Company
and its subsidiaries, including, among other things: (i) maintenance of certain
financial ratios and compliance with certain financial tests and limitations;
(ii) limitations on the payment of dividends, incurrence of additional
indebtedness and granting of certain liens; and (iii) restrictions on mergers,
acquisitions, asset sales, capital expenditures and investments.
 
SENIOR NOTES DUE 2005
 
     In July 1995, the Company sold $110,000,000 in aggregate principal amount
of 9.875% senior notes due 2005 (the "2005 Notes"). The 2005 Notes are general
unsecured obligations of the Company with interest payable semi-annually. The
2005 Notes are guaranteed on a senior unsecured basis, jointly and severally, by
each of the Company's principal wholly-owned domestic operating subsidiaries and
certain of its indirect wholly-owned subsidiaries. Except as noted below, the
2005 Notes are not redeemable at the Company's option prior to July 15, 2000.
Thereafter, the 2005 Notes will be redeemable, in whole or part, at the option
of the Company at various redemption prices as set forth in the 2005 Note
Indenture, plus accrued and unpaid interest thereon to the redemption date. In
addition, prior to July 15, 1998, the Company may, at its option, redeem up to
an aggregate of 30% of the principal amount of the 2005 Notes originally issued
with the net proceeds from one or more public equity offerings at the redemption
price specified of 109.875% plus accrued interest to the date of redemption.
Also, in the event of a change in control, the Company will be obligated to make
any offer to purchase all of the outstanding 2005 Notes at a redemption price of
101% of the principal amount thereof plus accrued interest to the date of
repurchase. Further, in certain circumstances, the Company will be required to
make an offer to repurchase the 2005 Notes at a price equal to 100% of the
principal amount thereof, plus accrued interest to the date of repurchase, with
the net cash proceeds of certain asset sales.
 
                                       80
<PAGE>   82
 
     The 2005 Note Indenture contains customary events of default and covenants
which limit (i) the incurrence of additional indebtedness; (ii) the issuance of
preferred stock by subsidiaries; (iii) the creation of liens; and (iv)
restrictions on sales of assets and subsidiary stock, mergers and
consolidations, payments to subsidiaries and transactions with affiliates.
 
SENIOR NOTES DUE 2004
 
     In October 1994, the Company sold $45 million in principal amount of 7.68%
senior notes due 2004 (the "2004 Notes"). The 2004 Notes require quarterly
interest payments due January 1, April 1, July 1 and October 1. The agreement
requires the Company to maintain consolidated adjusted net worth of $85 million,
plus 25% of cumulative net income for each year beginning in 1995, and a funded
debt to total capital ratio not greater than .65 to 1. The agreement also
prohibits the Company from consolidating or merging with another corporation
except under certain circumstances and from disposing of substantially all of
its assets. The 2004 Note Agreement gives the holders of the 2004 Notes the
option of having their 2004 Notes repurchased at the principal amount thereof in
the event of a Change of Control (as defined in the 2004 Note Agreement). In
addition, the 2004 Note Agreement contains events of default including (i) a
default in the payment of interest, (ii) a default in the payment of any
principal or required prepayment or premium, (iii) defaults under certain other
debt instruments, and (iv) certain events of insolvency or bankruptcy of the
Company or its subsidiaries. The 2004 Notes are secured equally and ratably with
the Credit Facility by the Company's and its domestic subsidiaries' inventory,
accounts receivable and certain intangibles and by a pledge of 100% of the
capital stock of wholly-owned domestic subsidiaries and up to 65% of the capital
stock of wholly-owned foreign subsidiaries.

     The Underwriters are obligated to take and pay for the total number of
Preferred Securities offered hereby if any such Preferred Securities are
purchased. In the event of default by any Underwriter, the Underwriting
Agreement provides that, in certain circumstances, purchase commitments of the
non-defaulting Underwriters may be increased or the Underwriting Agreement may
be terminated.
 
     The Underwriting Agreement provides that the Trust and the Company will
indemnify the several Underwriters against certain liabilities, including
liabilities under the Securities Act of 1933, as amended, and to make certain
contributions in respect thereof.
 
     The Trust and the Company have agreed, during the period beginning on the
date of the Underwriting Agreement and continuing to and including the date that
is 90 days after the closing date of the purchase of the Preferred Securities,
not to offer, sell, contract to sell or otherwise dispose of any preferred
securities, any preferred stock or any other securities (including any backup
undertakings of such preferred stock or other securities) of the Company or of
the Trust, in each case that are substantially similar to the Preferred
Securities, or any securities convertible into or exchangeable for the Preferred
Securities or such substantially similar securities of either the Trust or the
Company without the prior written consent of Smith Barney Inc.
 
     In view of the fact that the proceeds of the sale of the Preferred
Securities will ultimately be used to purchase the Convertible Debentures of the
Company, the Underwriting Agreement provides that the Company will pay as
compensation to the Underwriters $       per Preferred Security for the accounts
of the several Underwriters.
 
     The Underwriters propose to offer the Preferred Securities, in part,
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and to certain dealers at a price that represents
a concession not in excess of $       . The Underwriters may allow, and such
dealers may reallow, a concession not in excess of $       per Preferred
Security to certain brokers and dealers. After Preferred Securities are released
for sale to the public, the offering price and other selling terms may from time
to time be varied by the Underwriters.
 
     Application will be made to have the Preferred Securities approved for
listing on the NNM subject to official notice of issuance. Trading of the
Preferred Securities on the NNM is expected to commence within a 30-day period
after the date of this Prospectus.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and
Stockholders of Walbro Corporation:
 
     We have audited the accompanying consolidated balance sheets of Walbro
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1995,
1994 and 1993, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Walbro Corporation and
subsidiaries as of December 31, 1995, 1994 and 1993, and the results of their
operations and their cash flows for each of the years then ended in conformity
with generally accepted accounting principles.
 
     As discussed in Note 3 to the consolidated financial statements, effective
January 1, 1994, the Company changed its method of accounting for investments in
debt and equity securities. In addition, as discussed in Note 12 to the
consolidated financial statements, effective January 1, 1993, the Company
changed its method of accounting for postretirement benefits other than
pensions.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.
 
Principles of Consolidation:
 
     The consolidated financial statements include the accounts of Walbro
Corporation and its wholly-owned and majority-owned subsidiaries (the Company).
Investments in joint ventures are generally accounted for under the equity
method (Note 2). Significant transactions and balances among the Company and its
subsidiaries have been eliminated in the consolidated financial statements.
 
Foreign Currency Translation:
 
     The assets and liabilities of the Company's foreign operations are
generally translated into U.S. dollars at current exchange rates, and revenues
and expenses are translated at average exchange rates for the year. Resulting
translation adjustments are reflected as a separate component of stockholders'
equity.
 
     Transaction gains and losses that arise from exchange rate fluctuations on
transactions denominated in a currency other than the functional currency,
except those transactions which operate as a hedge of an identifiable foreign
currency commitment or as a hedge of a foreign currency investment position, are
included in the results of operations as incurred.
 
Accounts Receivable:
 
     Accounts receivable are net of allowances for doubtful accounts of
$978,000, $822,000 and $413,000 as of December 31, 1995, 1994 and 1993,
respectively.
 
Inventories:
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market. Inventories include raw materials and component parts, work-in-process
and finished products. Work-in-process and finished products inventories include
material, labor and manufacturing overhead costs.
 
     Inventory at December 31 consisted of the following:

     Amounts included in work-in-process and finished products in 1993 was not
material.
 
Plant and Equipment:
 
     The Company provides for depreciation of plant and equipment based upon the
acquisition costs and the estimated service lives of depreciable assets. The
straight-line method is the principal method used to compute depreciation for
financial reporting purposes. However, the units-of-production method is used to
compute depreciation of certain equipment. Estimated service lives of
depreciable assets are as follows: buildings and improvements - 10 to 30 years,
machinery and equipment - 5 to 10 years.
 
Marketable Equity Securities:
 
     Effective January 1, 1994, the carrying value of marketable equity
securities is market value (Note 3). During 1993, the carrying value of
marketable equity securities was based on the lower of cost or quoted

market value. Net unrealized losses on non-current marketable equity securities
that were deemed to be other than temporary were reflected in income. Realized
gains and losses on the sale of marketable equity securities are recognized in
income on the specific identification basis.
 
Goodwill:
 
     Goodwill consists of purchase price and related acquisition costs in excess
of the fair value of the identifiable net assets acquired. Goodwill is amortized
on a straight-line basis over 15 to 40 years. The Company evaluates the carrying
value of goodwill for potential impairment on an ongoing basis. Such evaluations
compare operating income before amortization of goodwill of the operations to
which goodwill relates to the amortization recorded. The Company also considers
future anticipated operating results, trends and other circumstances in making
such evaluations.
 
     Goodwill consisted of the following at December 31:

Income Taxes:
 
     The consolidated financial statements have been prepared in accordance with
the provisions of Statement of Financial Accounting Standards (SFAS) No. 109,
"Accounting for Income Taxes." The adoption of SFAS No. 109 as of January 1,
1993 did not have a material impact on the consolidated financial statements of
the Company.
 
     Deferred income taxes represent the effect of cumulative temporary
differences between income and expense items reported for financial statement
and tax purposes, and between the bases of various assets and liabilities for
financial statement and tax purposes. Deferred tax assets are reduced by a
valuation allowance if, based on the weight of evidence, it is deemed more
likely than not that the asset will not be realized.
 
Research and Development Costs:
 
     Research and development costs are charged to operations as incurred and
amounted to $16,742,000, $12,199,000 and $9,484,000 for 1995, 1994 and 1993,
respectively.
 
Financial Instruments:
 
     In order to manage exposure to fluctuations in foreign currency exchange
rates, the Company regularly enters into forward currency exchange contracts.
Gains and losses on contracts that hedge specific foreign currency commitments
are deferred and recognized in net income in the period in which the related
transaction is consummated. Gains and losses on contracts that hedge net
investments in foreign joint ventures or subsidiaries are recognized as
cumulative translation adjustments in stockholders' equity. Gains and losses on
forward currency exchange contracts that do not qualify as hedges are recognized
as other income or expense.
 
Per Share Information:
 
     Income per share is based on the weighted average number of shares
outstanding during each period. Shares used in the per share calculations were
8,609,431 in 1995, 8,602,077 in 1994 and 8,537,375 in 1993.

Reclassifications:
 
     Certain amounts in prior years' consolidated financial statements have been
reclassified to conform with the presentation used in 1995.
 
Use of Estimates:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to 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 expenses during the reported
period. Actual results could differ from these estimates.

     The above joint ventures are generally involved in the design and
manufacture of precision fuel systems products for the global automotive market.
 
     All of the above investments in joint ventures are accounted for using the
equity method. Certain adjustments are made to the joint ventures' income so
that recorded income is stated in accordance with United States generally
accepted accounting principles. At December 31, 1995 and 1994, the cumulative
effect of these adjustments was to increase the Company's equity in its joint
ventures by approximately $2,102,000 and $1,300,000, respectively. At December
31, 1995, the amount included in retained earnings as undistributed earnings of
foreign joint ventures was approximately $4,380,000.
 
     In December 1994, the Company entered into a joint venture (Korea
Automotive Fuel Systems, Ltd.) with Daewoo Precision Industries in Korea. Korea
Automotive Fuel Systems, Ltd. manufactures fuel sending units for the Korean
automotive market.
 
     In February 1993, the Company entered into a joint venture (Marwal do

     Dividends from joint ventures of approximately $415,000, $38,000 and
$45,000 were received by the Company during 1995, 1994 and 1993, respectively.
The Company had sales to joint ventures of approximately $29,280,000,
$20,407,000 and $20,456,000 for 1995, 1994 and 1993, respectively. Included in
accounts receivable are trade receivables from joint ventures of approximately
$9,583,000, $7,349,000 and $1,882,000 for 1995, 1994 and 1993, respectively. The
Company had purchases from joint ventures of approximately $22,977,000,
$15,329,000 and $11,820,000 for 1995, 1994 and 1993, respectively. Included in
accounts payable are trade payables to joint ventures of approximately
$3,995,000, $782,000 and $1,120,000 for 1995, 1994 and 1993, respectively.
 
NOTE 3. INVESTMENTS.
 
     Effective January 1, 1994, the Company adopted SFAS No. 115, "Accounting
for Certain Investments in Debt and Equity Securities." This Statement requires
that certain investments be classified into three separate categories:
"held-to-maturity", "available-for-sale", and "trading," each with different
accounting treatment. The Company classified its investments in common stock
securities as "available-for-sale" which required the Company to record these
investments at fair market value and record the gross unrealized holding gains
and losses, after-tax, as a separate component of stockholders' equity. The
impact of adoption at January 1, 1994 was to increase investments by
approximately $3,225,000 and to increase stockholders' equity by $2,096,000, net
of income taxes.
 
     As of December 31, 1995 and 1994, the fair market value of the Company's
investments classified as "available-for-sale" was approximately $5,456,000 and
$6,256,000, respectively, including gross unrealized holding gains of
approximately $1,272,000 ($827,000 after-tax) and $2,197,000 ($1,428,000
after-tax), respectively. At December 31, 1995 and 1994, the fair market value
of the Company's investments classified as "trading" was $2,641,000 and
$3,304,000, respectively. The change in net unrealized holding gain included in
earnings was not significant.
 
NOTE 4. DYNO ACQUISITION.
 
     On July 27, 1995, the Company acquired the plastic fuel tank business of
Dyno Industrier A.S (Dyno), Oslo, Norway for $129,758,000 in cash which is
subject to certain subsequent adjustments as defined in the Purchase Agreement.
Dyno is a leading designer, manufacturer and marketer of plastic fuel tank

     The acquisition was accounted for under the purchase method, and
accordingly, the assets purchased and liabilities assumed in the acquisition are
reflected in the accompanying consolidated balance sheet as of December 31, 1995
and the operations since the date of acquisition are included in the

     In connection with the acquisition, the Company will be required to
relocate certain facilities. The Company anticipates it will incur costs to move
to the new facilities and involuntarily terminate or relocate employees in
addition to other costs directly associated with the acquisition. The Company
has recorded a liability of approximately $7,758,000 related to these costs in
purchase accounting. The Company expects the relocation of these facilities and
employees to be substantially completed during 1996.
 
     The purchase price and related allocation may be revised within one year
from the acquisition based on revisions of preliminary estimates of fair values
and final working capital acquired made at the date of purchase. Such changes
are not expected to be significant.
 
     Assuming the acquisition had taken place as of the beginning of 1995 and
1994, the consolidated pro forma results of operations of the Company would have
been as follows, after giving effect to certain adjustments, including
depreciation and amortization adjustments, increased interest expense,
elimination of certain costs assumed by the seller and the related income tax
effects:

     In January 1994, the Company acquired a 60% interest in Fujian Hualong
Carburetor Co., Ltd. (Fujian), which manufactures and markets carburetors for
two-wheeled vehicles in China. In connection with the acquisition, the Company
exchanged approximately $1,500,000 for a 60% ownership interest in Fujian. This
acquisition was accounted for as a purchase. The purchase price approximated the
fair value of the net assets acquired. Fujian is included in the Company's
consolidated financial statements from the date of purchase. In November 1995,
the Company acquired an additional 10% of Fujian for $250,000.
 
     In May 1994, the Company acquired a 100% ownership interest in an
engineering firm in Canada (Walbro Canada) for an aggregate purchase price of
$352,000. This acquisition was accounted for as a purchase. The excess of the
purchase price over the fair value of the net assets acquired was approximately
$424,000 and is being amortized over 15 years. Walbro Canada is included in the
Company's consolidated financial statements from the date of purchase.
 
     In April 1993, the Company purchased the interests of its joint venture
partners in Walbro Korea Ltd. for a purchase price of approximately $640,000,
including related expenses. As a result, the Company now has 100% ownership.
Prior to this purchase, the Company owned 50% of Walbro Korea Ltd.'s common
stock and accounted for its investment under the equity method of accounting.
This acquisition was accounted for as a purchase. The excess of the purchase
price over the fair value of net assets acquired was approximately $800,000 and
is being amortized over 40 years. Walbro Korea Ltd. is included in the Company's
consolidated financial statements from the date of purchase.
 
     Pro forma results of these acquisitions, assuming they had taken place at
the beginning of each year presented, would not be materially different from the
results reported.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In July 1995, the Company sold $110,000,000 in aggregate principal amount
of 9.875% senior notes due 2005 (the "2005 Notes"). The 2005 Notes are general
unsecured obligations of the Company with interest payable semi-annually. The
2005 Notes are guaranteed on a senior unsecured basis, jointly and severally, by
each of the Company's principal wholly-owned domestic operating subsidiaries and
certain of its indirect wholly-owned subsidiaries. Except as noted below, the
2005 Notes are not redeemable at the Company's option prior to July 15, 2000.
Thereafter, the 2005 Notes will be redeemable, in whole or part, at the option
of the Company at various redemption prices as set forth in the 2005 Note
Indenture, plus accrued and unpaid interest thereon to the redemption date. In
addition, prior to July 15, 1998, the Company may, at its option, redeem up to
an aggregate of 30% of the principal amount of the 2005 Notes originally issued
with the net proceeds from one or more public equity offerings at the redemption
price specified in the 2005 Note Indenture plus accrued interest to the date of
redemption. Also in the event of a change in control, the Company will be
obligated to make an offer to purchase all of the outstanding 2005 Notes at a
redemption price of 101% of the principal amount thereof plus accrued interest
to the date of repurchase. Also, in certain circumstances, the Company will be
required to make an offer to repurchase the 2005 Notes at a price equal to 100%
of the principal amount thereof, plus accrued interest to the date of
repurchase, with the net cash proceeds of certain asset sales.
 
     In July 1995, the Company executed a new $135,000,000 credit facility (the
"Credit Facility"). The Credit Facility consists of a $135,000,000
multi-currency revolving loan facility for the Company and certain of its
wholly-owned domestic and foreign subsidiaries, including a $5,000,000 swing
line facility and a $17,000,000 letter of credit facility. The Credit Facility
has an initial term of five years, with annual one year extensions of the
revolving credit portion of the facility available at the lender's discretion.
At any time within three years after closing of the Credit Facility, the Company
may convert up to $70,000,000 of revolving credit loans under the Credit
Facility to term loans in minimum amounts of $15,000,000 with maturities not
exceeding seven years from the closing of the Credit Facility. Borrowings under
the Credit Facility bear interest at a per annum rate equal to the agent's base
rate or the prevailing interbank offered rate in the applicable offshore
currency market, plus an additional margin ranging from 0.5% to 1.75% based on
the specific financial ratios of the Company. Borrowings under the Credit
Facility bore interest at rates ranging from 7.5% to 8.5% as of December 31,
1995. The Company will also be required to pay a quarterly unused facility fee
of 0.08% to 0.5%, based on the Company's funded debt ratio. Borrowings under the
Credit Facility are secured by first liens on the inventory, accounts receivable
and certain intangibles of the Company and its wholly-owned domestic
subsidiaries and by a pledge of 100% of the stock of wholly-owned domestic
subsidiaries and 65% of the stock of wholly-owned foreign subsidiaries.
Collateral for the Credit Facility secures the Senior Notes on an equal and
ratable basis. The Company and its wholly-owned domestic subsidiaries guarantee
payment of domestic and foreign borrowings under the Credit Facility. The
Company's wholly-owned foreign subsidiaries guarantee payment of foreign
borrowings under the Credit Facility.
 
     In November 1995, the Company executed with the State of Connecticut, a
ten-year provisional term loan, in the original principal amount of $3,400,000,
to be used exclusively for the purchase of equipment and certain construction
costs. The loan requires payment of interest only for the first two years at a
fixed rate equal to 6% per annum and then repayment in equal monthly
installments of principal and interest over the remaining eight years with a
balloon payment of $1,387,000 at the end of the ten year contractual agreement.
However, if the Company meets certain employment targets and other measures,
some or all of this loan is forgivable during this ten year period.

     The Credit Facility contains numerous restrictive covenants including but
not limited to, the following matters: (i) maintenance of certain financial
ratios and compliance with certain financial tests and limitations which become
increasingly restrictive with the passage of time; (ii) limitations on payment
of dividends, incurrence of additional indebtedness and granting of certain
liens; (iii) restrictions on mergers, acquisitions, asset sales, sales of
subsidiary stock, capital expenditures and investments; (iv) issuance of
preferred stock by subsidiaries and (v) sale and leaseback transactions. The
Company received waivers and amendments to certain financial covenants from its
lenders at December 31, 1995 due to non-compliance with such covenants.
 
     During 1994, the Company entered into an agreement to lease certain
machinery under terms which qualified as a capital lease. As of December 31,
1995 and 1994, assets recorded under this capital lease were approximately
$5,032,000 and $5,109,000, respectively, net of accumulated amortization of
approximately $95,000 and $18,000, respectively.
 
     Aggregate minimum principal payment requirements on long-term debt,
including capital lease obligations, in each of the five years subsequent to
December 31, 1995 are as follows: 1996 -- $1,086,000; 1997 -- $1,252,000; 1998
- -- $7,949,000; 1999 -- $7,596,000; 2000 -- $64,603,000, and thereafter --
$151,989,000.
 
     In addition to long-term debt, the Company and its subsidiaries have line
of credit arrangements with foreign banks for short-term borrowings of
approximately $17,191,000, $11,919,000 and $7,200,000 at December 31, 1995, 1994
and 1993, respectively. The weighted average interest rate on short-term bank
borrowings outstanding under these arrangements was 6.1%, 6.7% and 5.6% as of
December 31, 1995, 1994 and 1993, respectively.
 
NOTE 9. COMMITMENTS AND CONTINGENCIES.
 
     The manufacture of automotive components entails the risk that a customer
or governmental authority may require the recall of one of the Company's
products or a product in which one of the Company's products has been installed.
The Company has taken and will continue to take all reasonable precautions to
avoid the risk of exposure to a recall or warranty claim that would have a
material effect on the financial position of the Company. The Company does not
believe that significant insurance coverage is available to protect against
potential product recall/warranty liability. The Company provides for warranty
claims on its products on a specific identification basis.
 
     Management believes that any liability resulting from these matters will
not have a material impact on the financial position or future results of
operations of the Company.

     At December 31, 1995, the cumulative amount of undistributed earnings of
foreign subsidiaries was approximately $21,300,000. No deferred U.S. income
taxes have been provided on these earnings as such amounts are deemed to be
permanently reinvested. If such earnings were remitted, the impact of foreign
withholding taxes would not be significant.
 
     As of December 31, 1995, the Company has net operating loss carryforwards
of approximately $13,832,000, which expire in varying amounts between 2003 and
2010, available from certain of its subsidiaries. The Company has recorded a
deferred tax asset of $4,231,000 associated with these carryforwards.
Realization is dependent on generating sufficient taxable income in specific
countries prior to the expiration of the loss carryforwards. Although
realization is not assured, management believes it is more likely than not that
all of the deferred tax asset will be realized. The amount of the deferred tax
asset considered realizable, however, could be reduced in the near term if
estimates of future taxable income during the carryforward period are reduced.
 
     Provisions for state income taxes are included in selling and
administrative expenses and amounted to $1,369,000 in 1995, $1,203,000 in 1994
and $722,000 in 1993.
 
NOTE 11. STOCK OPTION PLANS AND LONG-TERM INCENTIVE PLANS.
 
     The Company has a stock option plan, the Walbro Corporation 1983 Incentive
Stock Option Plan (1983 Plan), under which 155,850 shares of common stock are
reserved for issuance to officers and key employees.

Options may be granted for periods of up to ten years at prices greater than or
equal to the market value at the date of grant.
 
     In 1991, the Company adopted an incentive stock option plan, the Walbro
Corporation Equity Based Long Term Incentive Plan (Incentive Plan) under which
856,457 shares of common stock are reserved for issuance to officers, directors
and key employees. Options are granted yearly based on certain financial
performance criteria as compared to the annual business plan and other factors.
In addition, Stock Performance Award Grants (Grants) are awarded annually when
the common stock price appreciates and Grants are exchanged for common stock at
the end of the five-year term. If the Company's common stock price appreciates
at a 17% compounded rate over the term, the number of Grants awarded, valued at
the common stock price, will equal the dollar amount necessary to exercise the
stock options. Participants will receive a greater or lesser number of Grants
based on the actual market performance of the stock over the term. The number of
grants outstanding was 33,294, 30,915 and 31,912 as of December 31, 1995, 1994
and 1993, respectively.
 
     A summary of the stock option transactions of the 1983 Plan and the
Incentive Plan for the years ended December 31, 1995, 1994 and 1993 is as

     In 1991, the Company approved the Walbro Engine Management Corporation
(EMC) Incentive Compensation Plan (EMC Plan) which covers selected officers and
key employees of EMC. The purpose of the plan is to increase the proportion of
officer and key employee compensation tied to the profitability and cash flow of
EMC, a wholly-owned subsidiary of the Company. The EMC Plan requires EMC
management to amortize over a seven-year period, in annual installments of
interest and principal, an amount approximating the fair market value (FMV) of
EMC at July 1, 1991. If all required payments have been made at the end of the
fifth plan year, the participants will receive an amount equal to 15% of the FMV
of EMC. At that time, if the payments made are less than 100% but greater than
70% of the required amortization amount, the participants are eligible to
receive a pro-rata share of the 15% of FMV of EMC based on the actual repayment
percentage achieved. The Company has accrued approximately $5,044,000,
$3,100,000 and $1,480,000 as of December 31, 1995, 1994 and 1993, respectively,
under this plan.

NOTE 12. POSTRETIREMENT HEALTH BENEFITS.
 
     The Company provides postretirement health care, dental benefit and
prescription drug coverage to a limited number of current retirees.
Postretirement benefits are not available for active employees.
 
     Effective January 1, 1993, the Company changed its method of accounting for
the cost of these benefits from a pay-as-you-go (cash) method to an accrual
method as required by SFAS No. 106, "Employers' Accounting for Postretirement
Benefits Other than Pensions," and recognized the unfunded transition obligation
of $4,394,000 ($2,900,000 after-tax) as a one-time cumulative effect of change
in accounting.
 
     The following table reconciles the status of the accrued postretirement
benefit obligation at December 31:

     For measurement purposes, an 8% annual rate of increase was assumed in per
capita cost of covered health and dental care benefits for 1995. The rate was
assumed to gradually decrease to 5% by the year 2003 and remain at that level
thereafter. The health care cost trend rate assumption has a significant impact
on the accumulated postretirement benefit obligation and on future amounts
accrued. A one percentage point increase each year in the assumed health care
cost would increase the accumulated postretirement benefit obligation at
December 31, 1995 by $407,000 and the interest cost component of net periodic
postretirement benefit cost for the year ended December 31, 1996 by $30,000.
 
NOTE 13. PENSION PLANS.
 
     The Company sponsors pension plans covering substantially all domestic
collectively bargained employees and certain foreign employees. The plan
covering domestic collectively bargained employees provides benefits of stated
amounts for each year of service. Plans covering certain foreign employees
provide payments at termination which are based upon length of service,
compensation rate and whether termination was voluntary or involuntary. The
Company annually contributes to the plans covering domestic employees and
certain foreign employees amounts which are actuarially determined to provide
the plan with sufficient assets to meet future benefit payment requirements. The
plans covering foreign employees in certain countries are not funded.

     Total pension expense amounted to $251,000 in 1995, $239,000 in 1994 and
$280,000 in 1993. The Company recognizes currently the amount which would be
payable if employees covered by certain foreign plans terminated voluntarily.
Pension expense for the other plans is comprised of the following:

     The Company also sponsors a defined contribution plan for non-union

50% of each participant's before-tax contribution (up to 6% of the participant's
annual income) and retirement contribution of up to 3% (subject to change on an
annual basis) of a participant's annual income. The cost of defined
contributions charged to earnings during 1995, 1994 and 1993 was approximately
$2,255,000, $1,431,000 and $1,416,000, respectively.
 
     Certain non-union employees, excluding officers, are eligible to
participate in the Walbro Corporation Employee Stock Ownership Plan (ESOP). The
Company will make annual contributions to a trust in the form of either cash or
common stock of the Company. The amount of the annual contribution is
discretionary,

except that it must be sufficient to enable the trust to meet its current
obligations. The Company has guaranteed the ESOP's loan and is obligated to
contribute sufficient cash to the trust to repay the loan. Contribution expense
related to the ESOP amounted to $515,000, $365,000 and $302,000 in 1995, 1994
and 1993, respectively. Contribution expense is net of dividends of $105,000,
$210,000 and $106,000 in 1995, 1994 and 1993, respectively. As of December 31,
1995, 1994 and 1993, the following are held by the ESOP: 194,000, 170,000 and
152,000 allocated shares, respectively, and 56,000, 82,000 and 109,000 suspense
(unallocated) shares, respectively, which are all committed-to-be-released.
 
NOTE 14. DISCLOSURES ABOUT DERIVATIVE FINANCIAL INSTRUMENTS AND FAIR VALUE OF
         FINANCIAL INSTRUMENTS.
 
     The Company is a party to financial instruments with off-balance sheet risk
in the normal course of business to help meet financing needs and to reduce
exposure to fluctuating foreign currency exchange rates. The Company is exposed
to credit loss in the event of nonperformance by the other parties to the
financial instruments described below. However, the Company does not anticipate
nonperformance by the other parties. The Company does not engage in trading
activities with these financial instruments and does not generally require
collateral or other security to support these financial instruments. The
notional amounts of derivatives summarized below do not represent the amounts
exchanged by the parties and, thus, are not a measure of the exposure of the
Company through its use of derivatives. The amounts exchanged are calculated on
the basis of the notional amounts and the other terms of the derivatives.
 
Financial Instruments with Off-Balance Sheet Risk
 
     The Company enters into forward currency exchange contracts to manage its
foreign currency exchange risk. There were no contracts outstanding as of
December 31, 1995. As of December 31, 1994 and 1993, the notional amounts of
contracts outstanding were $14,000,000 and $30,000,000, respectively.
 
     The Company enters into forward currency exchange contracts to manage its
exposure against foreign currency fluctuations related to firm commitments. As
of December 31, 1994, the Company had one forward currency exchange contract
which matured in 1995 and exchanged 86,332,000 French francs. Total losses on
this contract of approximately $1,800,000 were recorded as a deferred asset
during 1994. This asset is being recognized based on actual purchases of the
related commitments. The amounts included in the equity in (income) loss of
joint ventures in the accompanying consolidated statements of income related to
this contract for the year ending December 31, 1995 and 1994 is approximately
$720,000 and $600,000, respectively. The balance remaining to be amortized at
December 31, 1995 and 1994 is $480,000 and $1,200,000, respectively.
 
     The Company enters into forward currency exchange contracts to hedge its
equity investments in certain foreign joint ventures. During 1994, the Company
had one forward currency exchange contract, which matured during 1994, which
exchanged 44,100,000 French francs. At December 31, 1994, losses of $1,020,000
on a hedge of a net investment in a foreign joint venture are included in
stockholders' equity.
 
     The Company enters into forward currency exchange contracts to reduce its
exposure against fluctuations in foreign currency exchange rates. During 1995,
the Company had twenty-one forward currency exchange contracts which matured
during 1995, which exchanged 1,015,000,000 Japanese yen and 15,300,000 Singapore
dollars. During 1994, the Company had twenty-one forward currency exchange
contracts which matured during 1994, which exchanged 1,133,000,000 Japanese yen,
20,100,000 Deutsche marks and 15,100,000 Singapore dollars. The amounts included
in foreign currency exchange loss in the accompanying consolidated statements of
income related to these contracts were a gain of $929,000 for the year ending
December 31, 1995 and a loss of $1,200,000 for the year ending December 31,
1994.

Fair Value of Financial Instruments
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
          Cash and short-term financial instruments
 
        The fair values are estimated to be equal to carrying values because of
        the short-term, highly liquid nature of these instruments.
 
          Notes receivable
 
        The fair value is estimated using the expected future cash flows
        discounted at current interest rates.
 
          Marketable equity securities
 
        The fair value of marketable equity securities is estimated by quoted
        market prices when the investment is traded on a public stock exchange.
        For investments not publicly traded, a combination of book value and
        fair market value of assets is used.
 
          Long-term debt
 
        The fair value of the Company's public debt is estimated using quoted
        market prices. The fair value of the Company's other long-term debt is
        estimated using the expected future cash flows discounted at the current
        interest rates offered to the Company for debt of the same remaining
        maturities.
 
          Forward currency exchange contracts
 
        The fair value of forward currency exchange contracts is estimated by
        obtaining quotes from brokers.
 
     The estimated fair values of the Company's financial instruments are as
follows:

NOTE 17. STOCKHOLDERS' EQUITY.
 
     The Company has a stock rights plan which entitles the holder of each
right, upon the occurrence of certain events, to purchase one one-hundredth of a
share of a new series of preferred stock for $75. Furthermore, if the Company is
involved in a merger or other business combination at any time after the rights
become exercisable, the rights will entitle the holder to buy the number of
shares of common stock of the acquiring company having a market value of twice
the then current exercise price of each right. Alternatively, if a 15% or more
shareholder acquires the Company by means of a reverse merger in which the
Company and its stock survives, or engages in self-dealing transactions with the
Company, or if any person acquires 50% or more of the Company's common stock,
then each right not owned by a 15% or more shareholder will become exercisable
for the number of shares of common stock of the Company having a market value of
twice the then current exercise price of each right. The rights, which do not
have voting rights, expire in December 1998 and may be redeemed by the Company
at a price of $.01 per right at any time prior to their expiration or the time
they become exercisable.
 
     The Company has authorized 1,000,000 shares of $1.00 par value preferred
stock.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) ACQUISITION OF DYNO INDUSTRIER FUEL SYSTEMS BUSINESS
 
     On July 27, 1995, the Company, through certain of its wholly-owned
subsidiaries, acquired the Fuel Systems Business of Dyno Industrier A.S, Oslo,
Norway ("Dyno"). Dyno supplies plastic fuel tanks to most European vehicle
manufacturers through production facilities in Belgium, France, Germany, Norway,
Spain and the United Kingdom.
 
     This acquisition was accounted for as a purchase and, accordingly, the
operating results of Dyno have been included in the accompanying financial
statements since the date of the acquisition. The results of operations for the
three months and nine months ended September 30, 1996 include the results of
Dyno, while the results of operations for the three months and nine months ended
September 30, 1995 only include the results of Dyno after July 27, 1995.
 
     Assuming the acquisition had taken place as of the beginning of 1995, the
consolidated pro forma results of operations of the Company for the three months
and nine months ended September 30, 1995 would have been as follows, after
giving effect to certain adjustments consisting principally of management's
estimates of depreciation and amortization expense resulting from the market
valuation of Dyno net assets acquired, interest expense on acquisition debt and
related tax adjustments (Unaudited; in thousands, except per share data):

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify any persons, including directors and officers, who are
(or are threatened to be made) parties to any threatened, pending or completed
legal action, suit or proceeding (whether civil, criminal, administrative or
investigative), by reason of their being directors or officers of the
corporation. The indemnity may include expenses, attorneys' fees, judgments,
fines and amounts paid in settlement, provided such sums were actually and
reasonably incurred in connection with such action, suit or proceeding and
provided the director or officer acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests,
and, in the case of criminal proceedings, provided he had no reasonable cause to
believe his conduct was unlawful. A corporation may indemnify directors and
officers in a derivative action (in which suit is brought by a stockholder on
behalf of the corporation) under the same conditions, except that no
indemnification is permitted without judicial approval if the director or
officer is adjudged liable to the corporation. If the director or officer is
successful on the merits or otherwise in defense of any actions referred to
above, the corporation must indemnify him against the expenses and attorneys'
fees he actually and reasonably incurred.
 
     Article VIII of the Company's By-Laws provides that the Company shall
indemnify its officers and directors to the fullest extent permitted by Section
145.
 
     Under an existing policy of insurance, the Company is entitled to be
reimbursed for certain indemnity payments it is required or permitted to make to
directors and officers of the Company.
 
     Under the Trust Agreement, the Company will agree to indemnify each of the
Trustees of Walbro Capital Trust or any predecessor Trustee for Walbro Capital
Trust, and to hold each Trustee harmless against, any loss, damage, claims,
liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
Trust Agreement, including the costs and expenses of defending itself against
any claim or liability in connection with the exercise or performance of any of
its powers or duties under the Trust Agreement.

ITEM 17. UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the provisions referred to in Item 15 (other than the
insurance policies referred to therein), or otherwise, the Registrants have been
advised that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrants of expenses
incurred or paid by a director, officer or controlling person of the Registrants
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrants will, unless in the opinion of their counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue. The undersigned Registrants hereby
undertake that:
 
     (1) For purposes of determining any liability under the Securities Act, the
        information omitted from the form of prospectus filed as part of a
        registration statement in reliance upon Rule 430A and contained in the
        form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
        (4) or 497(h) under the Securities Act shall be deemed to be part of the
        registration statement as of the time it was declared effective.
 
     (2) For the purposes of determining any liability under the Securities Act,
        each post-effective amendment that contains a form of prospectus shall
        be deemed to be a new registration statement relating to the securities
        offered therein, and the offering of such securities at that time shall
        be deemed to be the initial bona fide offering thereof.

                        (Pursuant to Section 151 of the
                       Delaware General Corporation Law)

                   __________________________________________

     WALBRO CORPORATION, a corporation organized and existing under the General
Corporation Law of the State of Delaware (hereinafter called the "Company"),
hereby certifies that the following resolution was adopted by the Board of
Directors of the Company as required by Section 151 of the General Corporation
Law at a meeting duly called and held on December 6, 1988:

     RESOLVED, that pursuant to the authority granted to and vested in the Board
of Directors of this Company (hereinafter called the "Board of Directors" or the
"Board") in accordance with the provisions of the Certificate of Incorporation,
the Board of Directors hereby creates a series of Preferred Stock, par value
$.01 per share (the "Preferred Stock"), of the Company and hereby states the
designation and number of shares, and fixes the relative rights, preferences,
and limitations thereof as follows:

     Series A Junior Participating Preferred Stock:

     Section 1. Designation and Amount.  The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall initially be 40,878.  Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities or rights issued by the
Company convertible into Series A Preferred Stock and further provided that the
Board of Directors shall increase the number of shares constituting the Series A
Preferred Stock to the extent necessary for the Company to have available
sufficient shares of such Series A Preferred Stock available to fulfill all of
the Company's obligations to holders of securities and Rights of the Company.

<PAGE>   15
     Section 2. Dividends and Distributions.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Series A Preferred Stock with respect to dividends, the holders of shares
     of Series A Preferred Stock, in preference to the holders of Common Stock,
     par value $.50 per share (the "Common Stock"), of the Company, and of any
     other junior stock, shall be entitled to receive, when, as and if declared
     by the Board of Directors out of funds legally available for the purpose,
     dividends payable when and as dividends are declared on the Company's
     Common Stock in an amount, subject to the provision for adjustment
     hereinafter set forth, equal to 100 times the aggregate per share amount of
     all cash dividends, and 100 times the aggregate per share amount (payable
     in kind) of all non-cash dividends or other distributions, declared on the
     Company's Common Stock (except as provided in the next sentence).  In the
     event the Company shall at any time declare or pay any dividend on the
     Common Stock payable in shares of Common Stock, or effect a subdivision or
     combination or consolidation of the outstanding shares of Common Stock (by
     reclassification or otherwise than by payment of a dividend in shares of
     Common Stock) into a greater or lesser number of shares of Common Stock,
     then in each such case the amount to which holders of shares of Series A
     Preferred Stock were entitled immediately prior to such event under the
     preceding sentence shall be adjusted by multiplying such amount by a
     fraction, the numerator of which is the number of shares of Common Stock
     outstanding immediately after such event and the denominator of which is
     the number of shares of Common Stock that were outstanding immediately
     prior to such event.

          (b) The Company shall declare a dividend or distribution on the Series
     A Preferred Stock as provided in paragraph (A) of this Section immediately
     after it declares a dividend or distribution on the Common Stock.

     Section 3. Voting Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

          (A) Each share of Series A Preferred Stock shall entitle the holder
     thereof to 100 votes on all matters submitted to a vote of the stockholders
     of the Company.

          (B) Except as otherwise provided herein, in any other Certificate of
     Designations creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A Preferred Stock and the holders
     of shares of Common Stock and the holders of shares of Common Stock and any
     other capital stock of the Company having general voting rights shall vote
     together as one class on all matters submitted to a vote of stockholders of
     the Company.

          (C) Except as set forth herein, or as otherwise provided by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

<PAGE>   16
     Section 4. Reacquired Shares.  Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof.  All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as part of a new series of Preferred Stock subject to
the conditions and restrictions on issuance set forth herein, in the Certificate
of Incorporation, or in any other Certificate of Designations creating a series
of Preferred Stock or any similar stock or as otherwise required by law.

     Section 5. Liquidation, Dissolution or Winding Up.  Upon any liquidation,
dissolution or winding up of the Company, no distribution shall be made (1) to
the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received an aggregate amount per share, subject to the provisions for adjustment
hereinafter set forth, equal to 100 times the aggregate amount to be distributed
per share to holders of shares of Common Stock.  In the event the Company shall
at any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     Section 6. Consolidation, Merger, etc.  In case the Company shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly provisions for
adjustment hereinafter set forth, equal to 100 times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged.  In the event the Company shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount set forth in the preceding sentence with respect to
the exchange or change of shares of Series A Preferred Stock shall be adjusted
by multiplying such amount by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     Section 7. No Redemption.  The shares of Series A Preferred Stock shall not
be redeemable.



                                      -3-
<PAGE>   17
     Section 8. Rank.  The Series A Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Company's Preferred Stock.

     Section 9. Amendment.  The Certificate of Incorporation of the Company
shall not be amended in any manner which would materially alter or change the
powers, preferences or special rights of the Series A Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of at least
two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

     IN WITNESS WHEREOF, this Certificate of Designations is executed on behalf
of the Company by its Chairman of the Board and attested by its Secretary this
6th day of December, 1988.

                               WALBRO CORPORATION

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware

     Walbro Corporation, a Delaware corporation (the "Corporation"), certifies
that pursuant to the authority contained in its Restated Certificate of
Incorporation and in accordance with the provisions of Section 151 of the
General Corporation Law of the State of Delaware, its Board of Directors has
adopted the following resolution creating a series of its Preferred Stock, $1.00
par value per share, designated as Series A Increasing Rate Perpetual
Convertible Cumulative Preferred Stock;

     RESOLVED, that a series of the class of authorized Preferred Stock, $1.00
par value per share, of the Corporation (the "Preferred Stock") be hereby
created, and that the designation and amount thereof and the voting powers,
preferences and relative, participating, optional and other special rights of
the shares of such series, and the qualifications, limitations or restrictions
thereof are as follows:

     Section 1. Designation and Amount.  The shares of such series shall be
designated as the "Series A Increasing Rate Perpetual Convertible Cumulative
Preferred Stock" (the "Series A Preferred Stock") and the number of shares
constituting such series shall be 350,000, which number may be decreased (but
not increased) by the Board of Directors without a vote of stockholders;
provided, however, that such number may not be decreased below the number of
then currently outstanding shares of Series A Preferred Stock.

     Section 2. Dividends and Distributions.

          (a) The holders of shares of Series A Preferred Stock, in preference
     to the holders of shares of the Common Stock, $0.50 par value per share
     (the "Common Stock"), of the Corporation and of any other capital stock of
     the Corporation ranking junior to the Series A Preferred Stock as to
     payment of dividends, shall be entitled to receive, when and as declared by
     the Board of Directors in accordance with the Delaware General Corporation
     Law, out of funds legally available for the payment of dividends,
     cumulative cash dividends at the annual rate set forth below, and no more,
     payable in quarterly payments on September 30, December 31, March 31 and
     June 30 in each year (each such date being referred to herein as a
     "Dividend Payment Date"), commencing on the first Dividend Payment Date
     which is at least 10 days after the date of original issue of the Series A
     Preferred Stock.  The annual dividend rate on the Series A Preferred Stock
     shall be equal to the Base Rate (as defined below), plus the applicable
     Margin (as defined below), if any; provided, however that in no event shall

<PAGE>   19
     Payment Date exceed 15%; provided, further that the first dividend payment
     shall be reduced by an amount equal to $25,000.

          (b) For purposes of paragraph (a) of this Section 2, the following
     terms shall have the respective meanings assigned to them herein. "Margin"
     shall be (i) 0% through and until March 31, 1988; (ii) 3% on and after
     April 1, 1988 and through and until June 30, 1988; (iii) 6% on and after
     July 1, 1988 and through and until September 30, 1988; (iv) 9% on and after
     October 1, 1988 and through and until December 31, 1988; (v) 12% on or
     after January 1, 1989 and through and until March 31, 1989; and (vi) 15% on

     Manufacturers Hanover Trust Company, Citibank, N.A., Morgan Guaranty Trust
     Company of New York, Chemical Bank and The Chase Manhattan Bank, N.A.
     "Prime Rate" shall mean the respective prime rate quoted by any Determining
     Bank.  The "Average Prime Rate" for any Determining Bank shall be a
     fraction, the numerator of which is the sum of the Prime Rates in effect at
     the close of business on each Business Day in the three-month period in
     question (as provided below) and the denominator of which is the number of
     Business Days in such period; provided, however, that for purposes of
     determining the amount of accrued dividends on the Series A Preferred Stock
     as of any date, the period for determining the Average Prime Rate shall end
     on the date of determination.  The "Base Rate" for the immediately
     preceding three-month period shall be determined on each September 29,
     December 30, March 30 and June 29, commencing on December 30, 1987, and
     shall be equal to the highest Average Prime Rate of any of the Determining
     Banks for the immediately preceding three-month period.

          (c) Dividends payable pursuant to paragraph (a) of this Section 2
     shall begin to accrue on a daily basis and be cumulative from the date of
     original issue of the Series A Preferred Stock.  The amount of dividends so
     payable shall be determined on the basis of twelve 30-day months and a
     360-day year.  Accrued but unpaid dividends shall not bear interest.
     Dividends paid on the shares of Series A Preferred Stock in an amount less
     than the total amount of such dividends at the time accrued and payable on
     such shares shall be allocated pro rata on a share-by-share basis among all
     such shares at the time outstanding.  The Board of Directors may fix a
     record date for the determination of holders of shares of Series A
     Preferred Stock entitled to receive payment of a dividend declared thereon,
     which record date shall be no more than 60 days prior to the date fixed for
     the payment thereof.

     Section 3. Voting Rights.  In addition to any voting rights provided
elsewhere herein and in the Corporation's Restated Certificate of Incorporation,
as it may be amended or restated from time to time (the "Certificate of
Incorporation"), and any voting rights provided by law, the holders of shares of
Series A Preferred Stock shall have the following voting rights:

          (a) Each share of Series A Preferred Stock shall initially be entitled
     to 3.076923 votes, subject to adjustment in the manner set forth in clauses
     (i), (ii) and (iii) of paragraph (b) of Section 8; provided, however, that
     the right to exercise any vote pursuant to this paragraph (a) shall be
     subject to satisfaction of any applicable waiting period with respect to
     any acquisition of shares of Series A Preferred Stock under the
     Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, including
     any 



                                     - 2 -
<PAGE>   20

     extensions thereof.  Except as otherwise provided herein, by the
     Certificate of Incorporation, or by law, the shares of Series A Preferred
     Stock and the shares of Common Stock (and any other shares of capital stock
     of the Corporation at the time entitled thereto) shall vote together as one
     class on all matters submitted to a vote of stockholders of the
     Corporation.

          (b) So long as any shares of Series A Preferred Stock shall be
     outstanding and unless the approval of a greater number of shares shall
     then be required by law, without first obtaining the approval of the
     holders of at least two-thirds of the number of then-outstanding shares of
     Series A Preferred Stock, voting as a single class, given in person or by
     proxy at a meeting at which the holders of such shares shall be entitled to
     vote separately as a class, the Corporation shall not:  (i) authorize or
     issue shares of any class or series of stock having any preference or
     priority as to dividends or upon liquidation ("Senior Stock") over or on a
     parity with the Series A Preferred Stock; (ii) reclassify any shares of
     stock of the Corporation into shares of Senior Stock; (iii) authorize or
     issue any security exchangeable for, convertible into, or evidencing the
     right to purchase any shares of Senior Stock; or (iv) amend, alter or
     repeal the Certificate of Incorporation to alter or change the preferences,
     rights or powers of the Series A Preferred Stock so as to affect the Series
     A Preferred Stock adversely.

          (c) If (i) on any Dividend Payment Date for the Series A Preferred
     Stock the dividends accrued pursuant to Section 2 hereof, for any two
     quarterly periods shall not have been paid in full or (ii) at any time
     during which General Electric Credit Corporation ("GECC") shall hold at
     least 50,000 shares of Series A Preferred Stock the Company shall violate
     in any material respect any provision of Section 5 of the Stock Purchase
     Agreement dated as of September 29, 1987, by and between GECC and the
     Company (the "Purchase Agreement"), the holders of shares of Series A
     Preferred Stock shall have the right, voting together as a single class, to
     elect two directors; provided, however, that if at the time such right to
     elect two directors shall occur there shall be more than two members of the
     Board of Directors who are then, or who have within the past five years
     been, either officers or full-time employees of the Corporation (other than
     any such Directors elected by the holders of the Series A Preferred Stock
     pursuant to this subsection) (an "Officer-Director"), then the holders of
     shares of Series A Preferred Stock shall have the right, voting together as
     a single class, to elect such number of directors as is equal to the number
     of Directors of the Corporation who are then Officer-Directors (an
     "adjusted number" of Directors).  Such right to vote for the election of
     such directors may be exercised at any annual meeting or at any special
     meeting called for such purpose as hereinafter provided or at any
     adjournment thereof by the holders of a majority of all of the outstanding
     shares of Series A Preferred Stock, until such time as all dividends in
     arrears on the outstanding shares of Series A Preferred Stock shall have
     been paid in full (or such dividends shall have been declared and funds
     sufficient therefor set apart for payment) or any violation of any
     provision of Section 5 of the Purchase Agreement shall have been cured, as
     the case may be, at which time the term of officer of the directors so
     elected shall terminate automatically.  So long as such right to vote
     continues, the Secretary of the Corporation may call, and upon the written
     request of the holders of record of a majority of the outstanding shares of
     Series A Preferred Stock addressed to him at the principal office of the
     Corporation shall call, a special 



                                     - 3 -
<PAGE>   21

     meeting of the holders of such shares for the election of such directors as
     provided herein.  Such meeting shall be held within 30 days after delivery
     of such request to the Secretary, at the place and upon the notice provided
     by law and in the By-laws for the holding of meetings of stockholders;
     provided, however, that no such special meeting or adjournment thereof
     shall be held on a date less than 30 days before an annual meeting of
     stockholders or any special meeting in lieu thereof.  If at any such annual
     or special meeting or any adjournment thereof the holders of a majority of
     all of the then outstanding shares of Series A Preferred Stock entitled to
     vote in such election shall be present or represented by proxy, then the
     authorized number of directors shall be increased by two (or such adjusted
     number), and the holders of the Series A Preferred Stock shall be entitled
     to elect such additional directors.  Directors so elected shall serve until
     the next annual meeting or until their successors shall be elected and
     shall qualify, unless the term of office of the persons so elected as
     directors shall have terminated under the circumstances set forth in the
     second sentence of this paragraph (c).  In case of any vacancy occurring
     among the directors elected by the holders of the Series A Preferred Stock
     as a class, the remaining directors who shall have been so elected may
     appoint a successor to hold office for the unexpired term of the directors
     whose places shall be vacant.  If all of the directors so elected by the
     holders of the Series A Preferred Stock, voting as a class shall cease to
     serve as directors before their terms shall expire, the holders of the
     Series A Preferred Stock then outstanding and entitled to vote for such
     directors may at a special meeting of such holders called as provided
     above, elect successors to hold office for the unexpired terms of the

     rights of the holders thereof as stockholders of the Corporation, except
     the right to receive the redemption price (but without interest), shall
     cease and determine.  Any interest allowed on moneys so deposited shall be
     paid to the Corporation.  Any moneys so deposited which shall remain

     Preferred Stock, $1.00 par value per share, of the Corporation subject to

          Corporation, no distribution shall be made (i) to the holders of
          shares of Junior Stock, unless, prior thereto, the holders of shares
          of Series A Preferred Stock shall have received $100.00 per share,
          plus an amount per share equal to all accrued but unpaid dividends
          thereon, whether or not declared, to the date of such payment or (ii)
          to the holders of shares of Parity Stock, except distributions made
          ratably on the Series A Preferred Stock and all such Parity Stock in

<PAGE>   26
     of Series A Preferred Stock is entitled pursuant to paragraph (a) of
     Section 3, shall be subject to adjustment from time to time as follows:

               (i) In case the Corporation shall at any time or from time to
          time declare a dividend, or make a distribution, on the outstanding
          shares of Common Stock in shares of Common Stock or subdivide or
          reclassify the outstanding shares of Common Stock into a greater
          number of shares or combine or reclassify the outstanding shares of
          Common Stock into a smaller number of shares of Common Stock, then,
          and in each such case.

                    (A) the number of shares of Common Stock into which each
               share of Series A Preferred Stock is convertible shall be
               adjusted so that the holder of each share thereof shall be
               entitled to receive, upon the conversion thereof, the number of
               shares of Common Stock which the holder of a share of Series A
               Preferred Stock would have been entitled to receive after the
               happening of any of the events described above had such share
               been converted immediately prior to the happening of such event
               or the record date therefor, whichever is earlier; and

                    (B) the number of votes to which a holder of a share of
               Series A Preferred Stock is entitled pursuant to paragraph (a) of
               Section 3 shall be adjusted so that, after the happening of any
               of the events described above, such holder shall be entitled to a
               number of votes equal to (I) the number of votes to which such
               holder was entitled pursuant to paragraph (a) of Section 3
               immediately prior to such happening multiplied by (II) a
               fraction, the numerator of which is the number of shares of
               Common Stock into which one share of Series A Preferred Stock was
               convertible immediately after such happening and the denominator
               of which is the number of shares of Common Stock into which one
               share of Series A Preferred Stock was convertible immediately
               prior to such happening; and

                    (C) an adjustment made pursuant to this clause (i) shall
               become effective (x) in the case of any such dividend or
               distribution, (1) immediately after the close of business on the
               record date for the determination of holders of shares of Common
               Stock entitled to receive such dividend or distribution, for
               purposes of subclause (A), and (2) immediately after the close of
               business on the date of payment of such dividend or distribution,
               or the date of effectiveness of such subdivision or
               reclassification, for purposes of subclause (B), or (y) in the
               case of any such subdivision, reclassification or combination, at
               the close of business on the day upon which such corporate action
               becomes effective, for purposes of both subclause (A) and
               subclause (B).

               (ii) In case the Corporation shall issue rights or warrants to
          subscribe for or purchase Common Stock at a price per share less than
          the Current Market Price per share of the Common Stock on the record
          date for the determination of 



                                     - 9 -

<PAGE>   27
          stockholders entitled to receive such rights or warrants, then, and in
          each such case,

                    (A) the number of shares of Common Stock into which each
               share of Series A Preferred Stock is convertible shall be
               adjusted so that the holder of each share thereof shall be
               entitled to receive, upon the conversion thereof, the number of
               shares of Common Stock determined by multiplying the number of
               shares of Common Stock into which such share was convertible on
               the day immediately prior to such record date by a fraction, (I)
               the numerator of which is the sum of (1) the number of shares of
               Common Stock outstanding on such record date and (2) the number
               of additional shares of Common Stock which such rights or warrant
               entitle holders of Common Stock to subscribe for or purchase
               ("Offered Shares"), and (II) the denominator of which is the sum
               of (1) the number of shares of Common Stock outstanding on the
               record date and (2) a fraction, (x) the numerator of which is the
               product of the number of Offered Shares multiplied by the
               subscription or purchase price of the Offered Shares and (y) the
               denominator of which is the Current Market Price per share of
               Common Stock on such record date;

                    (B) the number of votes to which a holder of a share of
               Series A Preferred Stock is entitled pursuant to paragraph (a) of
               Section 3 shall be adjusted so that, after the happening of any
               of the events described in this subparagraph (ii) above, such
               holder shall be entitled to a number of votes equal to (I) the
               number of votes to which such holder was entitled pursuant to
               paragraph (a) of Section 3 immediately prior to such happening
               multiplied by (II) a fraction, the numerator of which is the
               number of shares of Common Stock into which one share of Series A
               Preferred Stock was convertible immediately after such happening
               and the denominator of which is the number of shares of Common
               Stock into which one share of Series A Preferred Stock was
               convertible immediately prior to such happening; and

                    (C) such adjustment shall become effective immediately after
               such record date, for purposes of clause (A), and immediately
               after the date of such issuance, for purposes of clause (B).

               (iii) In case the Corporation shall at any time or from time to
          time declare, order, pay or make a dividend or other distribution
          (including, without limitation, any distribution of stock or other
          securities or property or rights or warrants to subscribe for
          securities of the Corporation or any of its Subsidiaries by way of
          dividend) on its Common Stock, other than (A) regular quarterly
          dividends payable in cash, (B) shares of Common Stock which are
          referred to in subparagraph (i) of this paragraph (b), or (C) rights
          or warrants which are referred to in subparagraph (ii) of this
          paragraph (b), then, and in each such case, the number of shares of
          Common Stock into which each share of Series A Preferred Stock is
          convertible shall be adjusted so that the holder of each share

               thereof shall be entitled to receive, upon the conversion
               thereof, the number of shares of Common Stock determined by
               multiplying (1) the number of shares of Common Stock into which
               such share was convertible on the day immediately prior to the
               record date fixed for the determination of stockholders entitled
               to receive such dividend or distribution by (2) a fraction, the
               numerator of which shall be the Current Market Price per share of
               Common Stock as of such record date, and the denominator of which
               shall be such Current Market Price per share of Common Stock less
               the Fair Market Value per share of Common Stock (as determined in
               good faith by the Board of Directors of the Corporation, a
               certified resolution with respect to which shall be mailed to
               each holder of shares of Series A Preferred Stock) of such
               dividend or distribution; provided, however, that in the event of
               a distribution of shares of capital stock of a Subsidiary of the
               Corporation (a "Spin-Off") made to holders of shares of Common
               Stock, the numerator of such fraction shall be the sum of the
               Current Market Price per share of Common Stock as of the 35th
               Trading Day after the effective date of such Spin-Off and the
               Current Market Price of the number of shares (or the fraction of
               a share) of capital stock of the Subsidiary which is distributed
               in such Spin-Off in respect of one share of Common Stock as of
               such both Trading Day and the denominator of which shall be the
               Current Market Price per share of Common Stock as of such 35th
               Trading Day.  An adjustment made pursuant to this clause (iii)
               shall be made upon the opening of business on the next Business
               Day following the date on which any such dividend or distribution
               is made and shall be effective retroactively immediately after
               the close of business on the record date fixed for the
               determination of stockholders entitled to receive such dividend
               or distribution; provided, however, if the proviso to the
               preceding sentence applies, then such adjustment shall be made
               and be effective as of such 35th Trading Day after the effective
               date of such Spin-Off.

     For purposes of determining a conversion adjustment required by this
     paragraph (b) only, the shares of Series A Preferred Stock shall be deemed
     to be convertible, although they may not at the time of such determination
     be convertible pursuant to clauses (x), (y) or (z) of the first sentence of
     this Section 8.

               (c) In case of the consolidation or merger of the Corporation
          with another corporation, each share of Series A Preferred Stock shall
          thereafter be converted into and become, without any action on the
          part of the holder thereof, the number of shares of stock or other
          securities or cash or other property receivable upon such
          consolidation or merger by a holder of the number of shares of Common
          Stock into which such share was convertible immediately prior to such
          merger or consolidation.

               (d) If any adjustment in the number of shares of Common Stock
          into which each share of Series A Preferred Stock may be converted
          required pursuant to this Section 8 would result in an increase or
          decrease of less than 1% in the number of shares of Common Stock into
          which each share of Series A Preferred Stock is then convertible, the
          amount of any such adjustment shall be carried forward and adjustment
          with respect thereto shall be made at the time of and together with
          any subsequent adjustment, which, together with such amount and any
          other amount or amounts so carried forward, shall 



                                     - 11 -
<PAGE>   29

          aggregate at least 1% of the number of shares of Common Stock into
          which each share of Series A Preferred Stock is then convertible.

               (e) The Board of Director may increase the number of shares of
          Common Stock into which each share of Securities A Preferred Stock may
          be converted, in addition to the adjustments required by this Section
          8, as shall be determined by it (as evidenced by a resolution of the
          Board of Directors) to be advisable in order to avoid or diminish any
          income deemed to be received by any holder for federal income tax
          purposes of shares of Common Stock or Series A Preferred Stock
          resulting from any events or occurrences given rise to adjustments
          pursuant to this Section 8 or from any other similar event.

               (f) The holder of any shares of Series A Preferred Stock may
          exercise his right to convert such shares into shares of Common Stock
          by surrendering for such purpose to the Corporation, at its principal
          office or at such other office or agency maintained by the Corporation
          for that purpose, a certificate or certificates representing the
          shares of Series A Preferred Stock to be converted accompanied by a
          written notice stating that such holder elects to convert all or a
          specified whole number of such shares in accordance with the
          provisions of this Section 8 and specifying the name or names in which
          such holder wishes the certificate or certificates for shares of
          Common Stock to be issued.  In case such notice shall specify a name
          or names other than that of such holder, such notice shall be
          accompanied by payment of all transfer taxes payable upon the issuance
          of shares of Common Stock (or other securities) in such name or names.
          Other than such taxes, the Corporation will pay any and all transfer
          and other taxes (other than taxes based on income) that may be payable
          in respect of any issue or delivery of shares of Common Stock on
          conversion of Series A Preferred Stock pursuant hereto.  As promptly
          as practicable, and in any event within five business days after the
          surrender of such certificate or certificates and the receipt of such
          notice relating thereto and, if applicable, payment of all transfer
          taxes (or the demonstration to the satisfaction of the Corporation
          that such taxes have been paid), the Corporation shall deliver or
          cause to be delivered (i) certificates representing the number of
          validly issued, fully paid and nonassessable full shares of Common
          Stock to which the holder of shares of Series A Preferred Stock so
          converted shall be entitled and (ii) if less than the full number of
          shares of Series A Preferred Stock evidenced by the surrendered
          certificate or certificates are being converted, a new certificate or
          certificates, of like tenor, for the number of shares evidenced by
          such surrendered certificate or certificates less the number of shares
          converted.  Such conversion shall be deemed to have been made at the
          close of business on the date of giving of such notice and of such
          surrender of the certificate or certificates representing the shares
          of Series A Preferred Stock to be converted so that the rights of the
          holder thereof as to the shares being converted shall cease except for
          the right to receive shares of Common Stock in accordance herewith,
          and the person entitled to receive the shares of Common Stock shall be
          treated for all purposes as having become the record holder of such
          shares of Common Stock at such time.

               (g) Subject to the limitations on conversion set forth in the
          first sentence of Section 8 hereof, shares of Series A Preferred Stock
          may be converted at any time up 



                                     - 12 -
<PAGE>   30

          to the close of business on the second Business Day preceding the date
          fixed for redemption of such shares pursuant to Section 5 hereof.

               (h) Upon conversion of any shares of Series A Preferred Stock,
          the holder thereof shall be entitled to receive in cash any
          accumulated, accrued or unpaid dividends in respect of the shares so
          converted.

               (i) In connection with the conversion of any shares of Series A
          Preferred Stock, no fractions of shares of Common Stock shall be
          issued, but in lieu thereof the Corporation shall pay a cash
          adjustment in respect of such fractional interest in an amount equal
          to such fractional interest multiplied by the Current Market Price per
          share of Common Stock on the day on which such shares of Series A
          Preferred Stock are deemed to have been converted.

               (j) The Corporation shall at all times reserve and keep available
          out of its authorized and unissued Common Stock, solely for the
          purpose of effecting the conversion of the Series A Preferred Stock,
          such number of shares of Common Stock as shall from time to time be
          sufficient to effect the conversion of all then outstanding shares of
          Series A Preferred Stock.  The Corporation shall from time to time,
          subject to and in accordance with the laws of Delaware, increase the
          authorized amount of Common Stock if at any time the number of
          authorized shares of Common Stock remaining unissued shall not be
          sufficient to permit the conversion at such time of all then
          outstanding shares of Series A Preferred Stock.

          Section 9. Reports as to Adjustments.  Whenever the number of shares
     of Common Stock into which each share of Series A Preferred Stock is
     convertible and the number of votes per share of Series A Preferred Stock
     accorded a holder thereof is adjusted as provided in Section 8 hereof, the
     Corporation shall promptly mail to the holders of record of the outstanding
     shares of Series A Preferred Stock at their respective addresses as the
     same shall appear in the Corporation's stock records a notice stating that
     the number of shares of Common Stock into which the shares of Series A
     Preferred Stock are convertible and/or the number of votes per share they
     are accorded has been adjusted and setting forth the new number of shares
     of Common Stock (or describing the new stock, securities, cash or other
     property) into which each share of Series A Preferred Stock is convertible
     as a result of such adjustment, a brief statement of the facts requiring
     such adjustment and the computation thereof, and when such adjustment
     became effective.

                          CERTIFICATE OF DESIGNATIONS

                                       OF

               SERIES B 8% CUMULATIVE CONVERTIBLE PREFERRED STOCK

                               WALBRO CORPORATION


     Pursuant to Section 151 of the General Corporation Law of the State of
Delaware.

     Walbro Corporation, a Delaware corporation (the "Corporation"), certifies
that pursuant to the authority contained in its Restated Certificate of
Incorporation and in accordance with the provisions of Section 151 of the
General Corporation Law of the State of Delaware, its Board of Directors has
adopted the following resolution, creating a series of its Preferred Stock,
$1.00 par value per shares, designated as Series B 8% Cumulative Convertible
Preferred Stock:

     RESOLVED, that a Series of the class of authorized Preferred Stock, $1.00
par value per share, of the Corporation (the "Preferred Stock") be hereby
created, and that the designation and amount hereof and the voting powers,
preferences and relative, participating, optional and other special right of the
shares of such series, and the qualifications, limitations and restrictions
thereof are as follows:

     SECTION 1. DESIGNATION AND AMOUNT.  The shares of such series shall be
designated as the "Series B 8% Cumulative Convertible Preferred Stock" (the
"Series B Preferred Stock") and the number of shares constituting such series
shall be 50,000, which number may be decreased (but not increased) by the Board
of Directors without a vote of stockholders; provided, however, that such number
may not be decreased below the number of then currently outstanding shares of
Series B Preferred Stock.  Certain capitalized terms used herein are defined in
Section 13 hereof.

     SECTION 2. DIVIDENDS AND DISTRIBUTIONS

     (a) 8% Preferred Dividend.  When and as declared by the Corporation's Board
of Directors and to the extent permitted by the General Corporation Law of the
State of Delaware, the Corporation will pay preferential dividends to the
holders of the Series B Preferred Stock as provided in this Section 2(a). Except
as otherwise provided herein, dividends on each share of Series B Preferred
Stock will accrue cumulatively at the rate of 8% per annum of the initial $100
of the Liquidation Value thereof, from and including the date of issuance of
such share of Series B Preferred Stock to and including the date on which the
Liquidation Value of such share of Series B Preferred Stock is paid or such
share is redeemed or converted in accordance with the provisions hereof (the "8%
Preferred Dividends").  Such dividend will accrue whether or not it has been
declared and whether or not there are profits, surplus or other funds of the
Corporation legally available for the payment of the 8% Preferred Dividends. The
date on which the Corporation initially issues any shares of Series B Preferred
Stock will be deemed to the "date of issuance" regardless of the number of times
transfer of such share is made on the stock transfer books maintained by or for
the Corporation and regardless of the number of
<PAGE>   34
certificates which may be issues to evidence such share.  The 8% Preferred
Dividend shall be paid annually, commencing on January 4, 1989.  The 8%
Preferred Dividends are to be paid in preference to the holders of shares of
Common Stock, $0.50 par value per share (the "Common Stock"), of the Corporation
and of any other Junior Securities as to payment of dividends.

          (i) The 8% Preferred Dividends shall begin to accrue on a daily basis
     and be cumulative from the date of issuance of the Series B Preferred
     Stock.  The amount of 8% Preferred Dividends so payable shall be determined
     on the basis of twelve 30-day months and a 360-day year for the actual
     number of days elapsed.  Accrued but unpaid 8% Preferred Dividends shall
     not bear interest.  8% Preferred Dividends paid in an amount less than the
     total amount of such dividends at the time accrued and payable on such
     shares of Series B Preferred Stock shall be allocated pro rata on a
     share-by-share basis among all such shares of Series B Preferred Stock at
     the time outstanding.  The Board of Directors may fix a record date for the
     determination of holders of shares of Series B Preferred Stock entitled to
     receive payment of the 8% Preferred Dividend declared thereon, which record
     date shall be no more than 60 days prior to the date fixed for the payment
     thereof.

     (b) Common Stock Participating Dividend.  In addition to the 8% Preferred
Dividend payable on the shares of Series B Preferred Stock, if the Corporation
pays any dividends or makes any other distributions with respect to its Common
Stock, the Corporation shall pay at such time (the "Dividend Reference Date") to
each holder of Series B Preferred Stock the dividends or other distributions
which such holder would have been entitled to receive had such holder converted
all of the shares of Series B Preferred Stock held by him into Common Stock
immediately prior to the date as of which the holders of the Common Stock of
record entitled to such dividends or other distributions were determined (a
"Participating Dividend").  Participating Dividends paid in an amount less than
the total amount of such dividends at the time accrued and payable on such
shares of Participating Preferred Stock shall be allocated pro rata on a
share-by-share basis among all such shares of Participating Preferred Stock at
the time outstanding.  Any Participating Dividends not paid with respect to a
share of Series B Preferred Stock on any Dividend Reference Date or thereafter
will be added to such share's Liquidation Value.

          SECTION 3. LIQUIDATION.  Upon any liquidation, dissolution or winding
up of the Corporation, the holders of the Series B Preferred Stock will be
entitled to be paid, before any distribution or payment is made upon any Junior
Securities, but after any distribution or payment is made upon the Corporation's
Series A Preferred Stock (as hereinafter defined in Section 8), an amount in
cash equal to the aggregate Liquidation Value of all shares outstanding and the
holders of the Series B Preferred Stock will not be entitled to any further
payment.  If upon any such liquidation, dissolution or winding up of the
Corporation, the Corporation's assets to be distributed among the holders of the
Series B Preferred Stock are insufficient to permit payment to such holders of
the aggregate amount which they are entitled to be paid, then the entire assets
to be distributed will be distributed ratably among such holders and the holders
of Parity Securities based upon the aggregate Liquidation Value of the Series B
Preferred Stock and the Party Securities held by each such holder.  The
Corporation will mail written notice of such 




                                      -2-
<PAGE>   35

liquidation, dissolution or winding up, not less than 60 days prior to the
payment date stated therein, to each record holder of Series B Preferred Stock.
Neither the consolidation or merger of the Corporation into or with any other
corporation or corporations, nor the sale or transfer by the Corporation of all
or any part of its assets, nor the reduction of the capital stock of the
Corporation, will be deemed to be a liquidation, dissolution or winding up of
the Corporation within the meaning of this Section 3.

     SECTION 4. VOTING RIGHTS.  The holders of the Series B Preferred Stock
shall initially be entitled to four (4) votes per share of Series B Preferred
Stock, subject to adjustment in the manner set forth in Section 6(b).  Except as
otherwise provided herein, or by the Corporation's Restated Certificate of
Incorporation, or By-laws, the shares of Series B Preferred Stock and the shares
of Common Stock (and any other shares of capital stock of the Corporation at the
time entitled thereto) shall vote together as one class on all matters submitted
to a vote of stockholders of the Corporation.

     SECTION 5. REDEMPTION.

     (a) Redemption at the Option of Holder.  The holders of any shares of
Series B Preferred Stock shall have the right to have the Corporation redeem
all, but not less than all of the shares of Series B Preferred Stock then owned
by such holder (unless previously redeemed or converted in accordance with the
terms hereof), at any one time from and after January 4, 1993 but not later than
January 31, 1993 (the "Put Date") at a redemption price per share equal to the
Liquidation Value.

          (i) If the funds of the Corporation legally available for redemption
     of shares of Series B Preferred Stock on the Put Date are insufficient to
     redeem the total number of such shares to be redeemed on such date, those
     funds which are legally available will be used to redeem the maximum
     possible number of shares of Series B Preferred Stock ratably among the
     holders of such shares to be redeemed based upon the aggregate Liquidation
     Value of such shares hold by each such holder.  At any time thereafter when
     additional funds of the Corporation are legally available for the
     redemption of shares of Series B Preferred Stock, such funds will
     immediately be used to redeem the balance of such shares which the
     Corporation has become obligated to redeem on the Put Date but which it has
     not redeemed.

          (ii) Notice of any election of a holder of shares of Series B
     Preferred Stock to cause the Corporation to redeem shares held by such
     holder pursuant to this Section 5(a) (the "Put Notice") shall be given to
     the Corporation not less than thirty (30) days nor more than forty-five
     (45) days prior to the Put Date set forth in the Put Notice, at the
     Corporation, principal office or at such other office agency maintained for
     such purpose, either in person, by telefax, telecopier or by first class
     mail.  The Put Notice shall state the holder's name, address, his election,
     the number of shares subject to the election (which shall be not less than
     the total number of shares then held by such holder) and the Put Date.




                                      -3-
<PAGE>   36
          (iii) Upon surrender of the certificates for any shares of Series B
     Preferred Stock to be redeemed in accordance with the Put Notice (properly
     endorsed or assigned for transfer, if the Corporation's Board of Directors
     shall so require), and in any event not later than two business days
     following the Put Date, such shares shall be redeemed by the Corporation at
     the redemption price aforesaid.

     (b) Redemption at the Option of the Corporation.  The Corporation shall
have the right, at its election, to redeem all or any of the shares of Series B
Preferred Stock then outstanding (unless previously redeemed or converted in
accordance with the terms hereof), from and after January 4, 1993 but not later
than January 31, 1993 (the "Call Date") at a redemption price equal to the
Liquidation Value for each share of Series B Preferred Stock to be redeemed.

          (i) If the Corporation elects to redeem only a part of the outstanding
     shares of Series B Preferred Stock on the Call Date, the number of such
     shares to be redeemed from each holder thereof shall be determined by
     multiplying the total number of shares to be redeemed by a fraction, the
     numerator of which shall be the total shares held by said holder and the
     denominator of which shall be the total number of shares of Series B
     Preferred Stock then outstanding.

          (ii) If the funds of the Corporation legally available for redemption
     of shares of Series B Preferred Stock on the Call Date are insufficient to
     redeem the total number of shares to be redeemed on such date, those funds
     which are legally available will be used to redeem the maximum possible
     number of shares ratably among the holders of the shares of Series B
     Preferred Stock to be redeemed based upon the aggregate Liquidation Value
     of such shares hold by each such holder.  At any time thereafter when
     additional funds of the Corporation are legally available for the
     redemption of shares of Series B Preferred Stock, such funds will
     immediately be used to redeem the balance of the shares of Series B
     Preferred Stock which the Corporation has become obligated to redeem on the
     Call Date but which it has not redeemed.

          (iii) Notice of any election by the Corporation to redeem all or a
     portion of the outstanding shares of Series B Preferred Stock pursuant to
     this Section 5(b) (the "Call Notice") shall be given to all holders of
     record of the shares of Series B Preferred Stock not lose than thirty (30)
     nor more than forty-five (45) days prior to the Call Date set forth in the
     Call Notice at the addresses set forth in the stock transfer records
     maintained by or for the Corporation.  The Call Notice shall be delivered
     in person or by telefax or by first class mail, and shall state the
     holder's name, address, the Corporation's election and the number of shares
     of Series B Preferred Stock subject to the election.  Upon communication of
     any Call Notice the Corporation will become obligated to redeem the total
     number of shares of Series B Preferred Stock specified in the Call Notice
     on the Call Date.

          (iv) Upon surrender of the certificates for any shares of Series B
     Preferred Stock to be redeemed in accordance with the Call Notice (properly
     endorsed or assigned for transfer, if the Corporation's Board of Directors
     shall so require), such shares shall be redeemed by the Corporation at the
     redemption price aforesaid.  In case fewer than 




                                      -4-
<PAGE>   37
     the total number of shares of Series B Preferred Stock represented by any
     certificate are redeemed, a new certificate representing the number of
     unredeemed shares will be issued to the holder thereof without cost to such
     holder within three business days after surrender of the certificate
     representing the redeemed shares.

     (c) Dividends after Put Date or Call Date.  Any share of Series B Preferred
Stock which is redeemed pursuant to the provisions of subsection (a) or (b) of
this Section 5 shall not be entitled to accrue any dividend on or after the Put
Date or the Call Date, as the case may be, provided that the Corporation shall
pay the redemption price for any such share so redeemed.  At the time any share
of Series B Preferred Stock is redeemed pursuant to this Section 5, the rights
of any holders of such shares so redeemed shall cease, except for the right to
receive the redemption price therefor.

     (d) Status of Redeemed Shares.  Any shares of Series B Preferred Stock
which are redeemed or otherwise acquired by the Corporation shall be cancelled
and, upon cancellation, shall become authorized but unissued shares of Preferred
Stock of the Corporation and may be reissued an part of another series of
Preferred Stock.

     SECTION 6. CONVERSION.  Each share of Series B Preferred Stock may, at the
option of the holder thereof, be converted into shares of Common Stock on the
terms and conditions set forth in this Section 6 at any time after the date of
issuance and before the close of business on the second business day preceding
the Put Date or the Call Date.

     a) Conversion Ratio.  Subject to the provisions for Adjustment hereinafter
set forth, each share of Series B Preferred Stock shall be convertible in the
manner hereinafter set forth into four (4) fully paid and nonassessable shares
of Common Stock.

     b) Adjustments.  The number of shares of Common Stock into which each share
of Series B Preferred Stock is convertible, and the number of votes to which the
holder of a share of Series B Preferred Stock is entitled pursuant to Section 4,
shall be subject to adjustment from time to time as follows:

          (i) In case the Corporation shall at any time or from time to time
     declare a dividend, or make a distribution, on the outstanding shares of
     Common Stock in shares of Common Stock or subdivide or reclassify the
     outstanding shares of Common Stock into a greater number of shares or
     combine or reclassify the outstanding shares of Common Stock into a smaller
     number of shares of Common Stock into a smaller number of shares of Common
     Stock, then, and in each such case,

               (A) the number of shares of Common Stock into which each share of
          Series B Preferred Stock is convertible shall be adjusted so that the
          holder of each share thereof shall be entitled to receive, upon the
          conversion thereof, the number of shares of Common Stock which the
          holder of a share of Series B Preferred Stock would have been entitled
          to receive after the happening of any of the events described above
          had such share been converted immediately prior to the happening of
          such event or the record date therefor, whichever is earlier; and


                                      -5-
<PAGE>   38

               (B) the number of votes to which a holder of a share of Series B
          Preferred Stock is entitled pursuant to Section 4 shall be adjusted so
          that, after the happening of any of the events described above, such
          holder shall be entitled to a number of votes equal to (I) the number
          of votes to which such holder was entitled pursuant to Section 4
          immediately prior to such happening multiplied by (II) a fraction, the
          numerator of which is the number of shares of Common Stock into which
          one share of Series B Preferred Stock was convertible immediately
          after such happening and the denominator of which is the number of
          shares of Common Stock into which is the number of shares of Common
          Stock into which one share of Series B Preferred Stock was convertible
          immediately prior to such happening; and

               (C) an adjustment made pursuant to this clause (i) shall become
          effective (x) in the case of any such dividend or distribution, (1)
          immediately after the close of business on the record date for the
          determination of holders of shares of Common Stock entitled to receive
          such dividend or distribution, for purposes of subclause (A), and (2)
          immediately after the close of business on the date of payment of such
          dividend or distribution, or the date of effectiveness of such
          subdivision or reclassification, for purposes of subclause (B), or (y)
          in the case of any such subdivision, reclassification or combination,
          at the close business on the day upon which such corporate action
          becomes effective, for purposes of both subclause (A) and subclause
          (B).

          (ii) In case the Corporation shall issue rights or warrants to
     subscribe for or purchase Common Stock at a price per share less than the
     Current Market Price per share of the Common Stock on the record date for
     the determination of stockholders entitled to receive such rights or
     warrants, then, and in each such case,

               (A) the number of shares of Common Stock into which each share of
          Series B Preferred Stock is convertible shall be adjusted so that the
          holder of each share thereof shall be entitled to receive, upon the
          conversion thereof, the number of shares of Common Stock determined by
          multiplying the number of shares of Common Stock into which such share
          was convertible on the day immediately prior to such record date by a
          fraction, (I) the numerator of which is the sum of (1) the number of
          shares of Common Stock outstanding on such record date and (2) the
          number of additional shares of Common Stock which such rights of
          warrant entitle holders of Common Stock to subscribe for or purchase
          ("Offered Shares"), and (II) the denominator of which is the sum of
          (1) the number of Shares of Common Stock outstanding on the record
          date and (2) a fraction, (x) the numerator of which is the product of
          the number of Offered Shares multiplied by the subscription or
          purchase price of the Offered Shares and (y) the denominator of which
          is the Current Market Price per share of Common Stock on such record
          date;



                                      -6-
<PAGE>   39

               (B) the number of votes to which a holder of a share of Series B
          Preferred Stock is entitled pursuant to Section 4 shall be adjusted so
          that, after the happening of any of the events described in this
          subparagraph (ii) above, such holder shall be entitled to a number of
          votes equal to (I) the number of votes to which such holder was
          entitled pursuant to Section 4 immediately prior to such happening
          multiplied by (II) a fraction, the numerator of which is the number of
          shares of Common Stock into which one share of Series B Preferred
          Stock was convertible immediately after such happening and the
          denominator of which is the number of shares of Common Stock into
          which one share of Series A Preferred Stock was convertible
          immediately prior to such happening; and

               (C) such adjustment shall become effective immediately after such
          record date, for purposes of clause (A), and immediately after the
          date of such issuance, for purposes of clause (B).

          (iii) If the Corporation declares or pays a dividend upon the Common
     Stock payable otherwise than in cash out of earnings or earned surplus
     (determined in accordance with generally accepted accounting principles,
     consistently applied) except for a stock dividend payable in shares of
     Common Stock (a "Liquidating Dividend"), then the Corporation will pay to
     the holders of Series B Preferred Stock at the time of payment thereof the
     Liquidating Dividends which would have been paid on the Common Stock had
     such Series B Preferred been converted immediately prior to the date on
     which a record is taken for such Liquidating Dividend, or, if no record is
     taken, the date as of which the record holders of Common Stock entitled to
     such dividends are to be determined.

     (c) Organic Change.  Any capital reorganization, reclassification,
consolidation, merger or sale of all or substantially all of the Corporation's
assets to another Person which is effected in such a way that holders of Common
Stock or entitled to receive (either directly or upon subsequent liquidation)
stock, securities or assets with respect to or in exchange for common Stock is
referred to herein as an "Organic Change".  Prior to the consummation of any
Organic Change the Corporation will appropriate provisions (in form and
substance satisfactory to the holders of a majority of the Series B Preferred
Stock then outstanding) to insure that each of the holders of Series B Preferred
Stock will thereafter have the right to acquire and receive, in lieu of or in
addition to the shares of Common Stock immediately theretofore acquirable and
receivable upon the conversion of such holder's Series B Preferred Stock, such
shares of stock, securities or assets as such holder would have received in
connection with such Organic Change if such holder had converted his Series B
Preferred Stock immediately prior to such organic Change.  In any such case, the
Corporation will stake appropriate provisions (in form and substance
satisfactory to the holders of a majority of the Series B Preferred Stock then
outstanding) to insure that the provisions of this Section 5 will thereafter be
applicable to the Series B Preferred Stock.  The Corporation will not effect any
such consolidation, merger or sale, unless prior to the consummation thereof,
the successor corporation (if other than the Corporation) resulting from
consolidation or merger or the corporation purchasing such assets assume by
written instrument (in form reasonably satisfactory to the holders of a majority
of the 



                                      -7-
<PAGE>   40

Series B Preferred Stock then outstanding), the obligation to deliver to each
such holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holder may be entitled to acquire.

     (d) DeMinimis Adjustments.  If any adjustment in the number of shares of
Common Stock into which each share of Series B Preferred Stock may be converted
required pursuant to this Section 6 would result in an increase or decrease of
less than 1% in the number of shares of common Stock into which each share of
Series B Preferred Stock is then convertible, the amount of any such adjustment
shall be carried forward and adjustment with respect thereto shall be made at
the time of and together with any subsequent. adjustment, which, together with
such amount and any other amount or amounts so carried forward, shall aggregate
at least 1% of the number of shares of Common Stock into which each share of
Series B Preferred Stock is then convertible.

     (e) Procedure for Conversion.  The holder of any shares of Series B
Preferred stock may exercise his right to convert such shares into shares of
Common Stock by surrendering for such purpose to the Corporation, at its
principal office or at such other office or agency maintained by the Corporation
for that purpose, a certificate or certificates representing the shares of
Series B Preferred Stock to be converted accompanied by a written notice stating
that such holder elects to convert  all or a specified whole number of such
shares in accordance with the provisions of this Section 6 and specifying the
name or names in which such holder wishes the certificate or certificates for
shares of Common Stock to be issued.  In case such notice shall specify a name
or names other than that of such holder, such notice shall be accompanied by
payment of all transfer taxes payable upon the issuance of shares of Common
Stock (or other securities) in such name or names.  Other than such taxes, the
corporation will pay any and all transfer and other taxes (other than taxes
based on income) that may be payable in respect of any issue or delivery of
shares of Common Stock on conversion of Series B Preferred Stock pursuant
hereto.  As promptly as practicable, and in any event within five business days
after the surrender of such certificate or certificates and the receipt of such
notice relating thereto and, if applicable, payment of all transfer taxes (or
the demonstration to the satisfaction of the Corporation that such taxes have
bean paid), the corporation shall deliver or cause to be delivered (i)
certificates representing the number of validly issued, fully paid and
nonassessable full shares of Common Stock to which the holder of shares of
Series B Preferred Stock so converted shall be entitled and (ii) if less than
the full n r of shares of Series B Preferred Stock evidenced by the surrendered
certificate or certificates, of like tenor, for the number of shares evidenced
by such surrendered certificate or certificates lose the number of shares
converted. Such conversion shall be deemed to have been made at the close of
business on the date of giving of such notice and of such surrender of the
certificate or certificates representing the shares of Series B Preferred Stock
to be converted so that the rights of the holder thereof as to the shares being
converted shall cease except for the right to receive shares of Common Stock in
accordance herewith, and the person entitled to receive the shares of Common
Stock shall be treated for all purposes as having become the record holder of
such shares of Common Stock at such time.



                                      -8-
<PAGE>   41
     (f) Status of Converted Shares.  Any shares of Series B Preferred Stock
which are converted or otherwise acquired by the Corporation shall be cancelled,
and, upon cancellation, shall become authorized but unissued shares of Preferred
Stock of the Corporation and may be reissued as part of another series of
Preferred Stock.

     (g) Accrued Dividends.  Upon conversion of any shares of Series B Preferred
Stock, the holder thereof shall be entitled to receive in cash any accumulated,
accrued or unpaid dividends in respect of the shares so converted.

     (h) No Fractional Shares.  In connection with the conversion of any shares
of Series B Preferred Stock, no fractions of shares of Common Stock shall be
issued, but in lieu thereof the Corporation shall pay a cash adjustment in
respect of such fractional interest in an amount equal to such fractional
interest multiplied by the current Market Price per share of Common Stock on the
day on which such shares of Series B Preferred Stock are deemed to have been
converted.

     (i) Reservation of Shares of Common Stock.  The Corporation shall at all
times reserve and keep available out of its authorized and unissued Common
Stock, solely for the purpose of effecting the conversion of the Series B
Preferred Stock, such number of shares of Common Stock as shall from time to
time be sufficient to effect the conversion of all then outstanding shares of
Series B Preferred Stock.  The Corporation shall from time to time, subject to
and in accordance with the laws of Delaware, increase the authorized amount of
Common Stock if at any time the number of authorized shares of Common Stock
remaining unissued shall not be sufficient to permit the conversion at such time
of all then outstanding shares of Series B Preferred Stock.

     SECTION 7. REPORTS AS TO ADJUSTMENTS.  Whenever the number of shares of
Common Stock into which each share of Series B Preferred Stock is convertible
and the number of votes per share of Series B Preferred Stock accorded a holder
thereof is adjusted as provided in Section 6 hereof, the Corporation shall
promptly mail to the holders of record of the outstanding shares of Series B
Preferred Stock at their respective addresses as the same shall appear in the
Corporation's stock records a notice stating that the number of shares of Common
Stock into which the shares of Series B Preferred Stock are convertible and/or
the number of votes per share they are accorded has been adjusted and setting
forth the new number of shares of Common Stock (or describing the new stock,
securities, cash or other property) into which each share of Series B Preferred
Stock is convertible as a result of such adjustment, a brief statement of the
facts requiring such adjustment and the computation thereof, and when such
adjustment became effective.

     SECTION 8. RANKING.  The shares of series B Preferred Stock shall be
superior, as to the payment of dividends and distributions of whatever kind
including, without limitation distributions payable upon the dissolution,
liquidation and winding up of the Corporation, to all Junior Securities.  The
shares of Series B Preferred Stock shall rank pari passu, as to the payment of
all such dividends and distributions, with the shares of the Corporation's
Parity Securities.  The shares of the Series B Preferred Stock shall be
inferior, as to the payment of such dividends and distributions, to the shares
of the Corporation's Series A Increasing Rate 



                                      -9-
<PAGE>   42

Perpetual Convertible Cumulative Preferred Stock (the "Series A Preferred
Stock"), except to the extent that the Certificate of Designations respecting
said Series A Preferred Stock may be amended from and after the date hereof.

     SECTION 9. REGISTRATION OF TRANSFER.  The Corporation will keep at its
principal office a register for the registration of Series B Preferred Stock.
Upon the surrender of any certificate representing Series B Preferred Stock at
such place, the Corporation will, at the request of the record holder of such
certificate, execute and deliver (at the Corporation's expense) a new
certificate or certificates in exchange therefor representing in the aggregate
the number of shares represented by the surrender certificate.  Each such new
certificate will be registered in such name and will represent such number of
shares as is requested by the holder of the surrendered certificate and will be
substantially identical in form to the surrendered certificate, and dividends
will accrue on the Series B Preferred Stock represented by such new certificate
from the date to which dividends have been fully paid on such Series B Preferred
Stock represented by the surrender certificate.

     SECTION 10. REPLACEMENT.  Upon receipt of the evidence reasonably
satisfactory to the Corporation (an affidavit of the registered holder will be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing shares of Series B Preferred Stock, and in the case
of any such loss, theft or destruction, upon receipt of indemnity reasonably
satisfactory to the Corporation, or, in the case of any such mutilation upon
surrender of such certificate, the Corporation will (at its expense) execute and
deliver in lieu of such certificate of new certificate of like kind representing
the number of shares represented by such loss, stolen, or destroyed or mutilated
certificate and dated the date of such lost, stolen, destroyed or mutilated
certificate, and dividends will accrue on the Series B Preferred Stock
represented by such new certificate from the date to which dividends have been
fully paid on such lost, stolen, destroyed or mutilated certificate.

     SECTION 11. AMENDMENT.  No amendment, modification or waiver will be
binding or effective with respect to any provision of this Designation of
Series B Preferred Stock without the prior written consent of the holders of at
least majority of the then outstanding shares of Series B Preferred Stock.

     SECTION 12. NOTICE.  Except as otherwise expressly provided, all notices
referred to herein will be in writing and will be delivered by registered or
certified mail, return receipt requested, postage prepaid and will be deemed to
have been given when so mailed (i) to the Corporation at its principal
executive offices and (ii) to any stockholder, at such holder's address as it

                             WALBRO CAPITAL TRUST


    THIS DECLARATION OF TRUST is made as of December 17, 1996 (this
"Declaration"), by and among Walbro Corporation, a Delaware corporation, as
sponsor (the "Sponsor"), Bankers Trust (Delaware), a Delaware banking
corporation, as trustee, and Michael A. Shope, as trustee (jointly, the
"Trustees").  The Sponsor and the Trustees hereby agree as follows:

    1.   The trust created hereby shall be known as "Walbro Capital Trust" (the
"Trust"), in which name the Trustees or the Sponsor, to the extent provided
herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

    2.   The Sponsor hereby assigns, transfers, conveys and sets over to the
Trust the sum of $10.  Such amount shall constitute the initial trust estate. 
It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 Del. C. Section 3801, et seq. (the "Business Trust Act"), and that this
document constitute the governing instrument of the Trust.  The Trustees are
hereby authorized and directed to execute and file a certificate of trust with
the Delaware Secretary of State in such form as the Trustees may approve.


    3.   The Sponsor and the Trustees will enter into an amended and restated
Trust Agreement or Declaration satisfactory to each such party to provide for
the contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and Common Securities referred to therein.  Prior to the
execution and delivery of such amended and restated Trust Agreement or
Declaration, the Trustees shall not have any duty or obligation hereunder or
with respect of the trust estate, except as otherwise required by applicable
law or as may be necessary to obtain prior to such execution and delivery any
licenses, consents or approvals required by applicable law or otherwise.
Notwithstanding the foregoing, the Trustees may take all actions deemed proper
as are necessary to effect the transactions contemplated herein.

     4.   The Depositor and the Trustees hereby authorize and direct the
Depositor, as the sponsor of the Trust, (i) to file with the Securities and
Exchange Commission (the "Commission") and to execute, in the case of the 1933
Act Registration Statement and 1934 Act Registration Statement (as herein
defined), on behalf of the Trust, (a) the 1933 Act Registration Statement,
including pre-effective or post-effective amendments to such Registration
Statement, relating to the registration under the Securities Act of 1933, as
amended (the "1933 Act"), of the Preferred Securities of the Trust, (b) any
preliminary prospectus or prospectus supplement thereto relating to the
Preferred Securities required to be filed under the 1933 Act, and (c) a
Registration Statement on Form 8-A or other appropriate form (the "1934 Act
Registration Statement") (including all pre-effective and post-effective
amendments thereto) relating to the registration of the Preferred Securities of
the Trust under the Securities Exchange Act of 1934, as amended; (ii) to file
with the New York Stock Exchange or other exchange, and execute on behalf of
the Trust a listing application and all other applications, statements,
certificates,         
<PAGE>   2
agreements and other instruments as shall be necessary or desirable to cause
the Preferred Securities to be listed on the New York Stock Exchange or such
other exchange; (iii) to file and execute on behalf of the Trust such
applications, reports, surety bonds, irrevocable consents, appointments of
attorney for service of process and other papers and documents as shall be
necessary or desirable to register the Preferred Securities under the
securities or "Blue Sky" laws of such jurisdictions as the Depositor, on behalf
of the Trust, may deem necessary or desirable; and (iv) to execute,     deliver
and perform on behalf of the Trust an underwriting agreement with the Depositor
and the underwriter or underwriters of the Preferred Securities of the Trust. 
In the event that any filing referred to in clauses (i)-(iii) above is required
by the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, or state securities or Blue Sky laws to be executed on behalf
of the Trust by the Trustees, the Trustees, in their capacity as trustees of
the Trust, are hereby authorized and directed to join in any such filing and to
execute on behalf of the Trust any and all of the foregoing, it being
understood that the Trustees, in their capacity as trustees of the Trust, shall
not be required to join in any such filing or execute on behalf of the Trust
any such document unless required by the rules and regulations of the
Commission, the New York Stock Exchange or other exchange, or state securities
or Blue Sky laws.  In connection with all of the foregoing, Bankers Trust
(Delaware), solely in its capacity as trustee of the Trust, and the Depositor
hereby constitute and appoint Michael A. Shope as its true and lawful
attorney-in-fact and agent, with full power of substitution and resubstitution
for the Depositor or in the Depositor's name, place and stead, in any and all
capacities, to sign any and all amendments (including all pre-effective and
post-effective amendments) to the 1933 Act Registrations Statement and the 1934
Act Registration Statement and to file the same, with all exhibits thereto, and
any other documents in connection therewith, with the Commission, granting unto
said attorney-in-fact and agent full power and authority to do and perform each
and every act and thing requisite and necessary to be done in connection
therewith, as fully to all intents and purposes as the Depositor might or could
do in person, hereby ratifying and confirming all that said attorney-in-fact and
agent or his respective substitute or substitutes, shall do or cause to be done
by virtue hereof.

        5.      This Declaration may be executed in one or more counterparts.

        6.      The number of trustees of the Trust initially shall be two
and thereafter the number of trustees of the Trust shall be such number as
shall be fixed from time to time by a written instrument signed by the Sponsor
which may increase or decrease the number of trustees of the Trust; provided,
however, that to the extent required by the Business Trust Act, one trustee of
the Trust shall either be a natural person who is a resident of the State of
Delaware or, if not a natural person, an entity which has its principal place
of business in the State of Delaware.  Subject to the foregoing, the Sponsor is
entitled to appoint or remove without cause any trustee of the Trust at any
time.  Any trustee of the Trust may resign upon thirty days' prior notice to the
Sponsor.

        7.      This Declaration shall be governed by, and construed in
accordance with the laws of the State of Delaware (with regard to conflict of
laws principles).
