     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 January 3, 1997, the
last reported sale price of the Common Stock on the NNM was $18 1/4. Application
has been made to have the Preferred Securities approved for quotation on the
NNM, subject to official notice of issuance, under the symbol "WALBP". 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."

in conjunction with, the more detailed information and consolidated financial
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>   9
 
     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 January 3, 1997 was $18 1/4 per share.
                                 In connection with any conversion of a
                                 Preferred Security, the Conversion Agent (as
                                 defined herein) will exchange such Preferred
                                 Security for the appropriate principal amount
                                 of Convertible Debentures held by the Trust and
                                 immediately convert such Convertible Debentures
                                 into shares of Common Stock. 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. See "Description of the Preferred
                                 Securities -- Conversion Rights." In addition,

     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>   16
 
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>   17
 
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>   18
 
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>   19
 
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>   20
 
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>   21
 
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
the benefit of the holders of the Trust Securities and, in its capacity as the
holder, the Institutional Trustee will have the power to exercise all rights,
powers and privileges under the indenture pursuant to which the Convertible
Debentures are issued. In addition, the Institutional Trustee will maintain
exclusive control of a segregated non-interest bearing bank account (the
"Property Account") to hold all payments made in respect of the Convertible
Debentures for the benefit of the holders of the Trust Securities. The
Institutional Trustee will make payments of distributions and payments on
liquidation, redemption and otherwise for the holders of the Trust Securities
out of funds from the Property Account. The Guarantee Trustee will hold the
Guarantee for the benefit of the holders of the Preferred Securities. The
Company, as the direct or indirect holder of all the Common Securities, will
have the right, subject to certain restrictions constrained in the Declaration,
to appoint, remove or replace any Trustee and to increase or decrease the number
of Trustees. The Company will pay all fees and expenses related to the Trust and
the offering of the Trust Securities. See "Description of the Convertible
Debentures -- Miscellaneous."
 
     The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights are set forth in the
Declaration, the Delaware Business Trust Act, as amended (the "Trust Act") and
the Trust Indenture Act. See "Description of the Preferred Securities."
 
     The place of business and the telephone number of the Trust are the
principal executive offices and telephone numbers of the Company.

     On January 3, 1997, the closing price of the Common Stock as reported on
the NNM was $18 1/4. On January 2, 1997, the Common Stock was held by 1,123
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>   27
 
     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>   28
 
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>   29
 
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>   30
 
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>   31
 
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, which is scheduled to begin volume
production in the third quarter of 1997, is equipped with the Company's fuel
storage and delivery system. These products have a selling price of greater than
$120, 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 sold by General Motors, Ford and
Chrysler in North America in 1995 used 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
truck.
    
 
     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>   38
 
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>   39
 
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 management estimates 1995 production to
have been approximately 7.8 million units. 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.

  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>   41
 
     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>   43
 
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>   49
 
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
 
                                       48
<PAGE>   51
 
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>   52
 
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>   53
 
     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>   54
 
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>   56
 
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>   57
 
     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>   58
 
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>   60
 
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>   61
 
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>   62
 
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.
 
                                       60
<PAGE>   63
 
     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
materially 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>   65
 
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

     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>   67
 
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>   68
 
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>   69
 
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>   70
 
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>   71
 
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.
 
                                       69

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>   74
 
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>   75
 
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>   78
 
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>   79
 
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.

<PAGE>   80
 
                          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.
 
                                       78
<PAGE>   81

 
     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>   83
 
     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 has been 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.

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.

     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

depreciation and amortization adjustments, increased interest expense,
elimination of certain costs assumed by the seller and the related income tax

     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.

     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.
 
     In October 1994, the Company sold $45,000,000 of 7.68% senior notes (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 a
funded debt to total capital ratio not greater than .65 to 1 among other
measures.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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

     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

     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.

     The Company also sponsors a defined contribution plan for non-union
domestic employees under which the Company will make matching contributions of
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 15. LEASES.
 
     The Company has leased certain of its buildings, equipment and vehicles
under operating leases. The leases involving buildings contain options enabling
the Company to renew the leases at the end of the respective lease terms. Rent
expense was approximately $4,761,000, $3,324,000 and $2,655,000 in 1995, 1994
and 1993, respectively.

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.

     Worldwide operations are located in three geographic segments -- United
States, Europe and Far East and Other Foreign. The Europe geographic segment
includes operations in Belgium, France, Germany, Norway, Spain and the United
Kingdom. The Far East and Other Foreign geographic segment includes operations
in Japan, Singapore, Korea, China, Mexico and Canada. Sales between geographic
areas are accounted for at cost plus a margin for profit. Operating profit
consists of total sales less operating expenses excluding general corporate
expenses, interest expense and income taxes. Identifiable assets are those
assets used in the operations in each geographic area. Export sales from
domestic locations were approximately $45,485,000, $36,881,000 and $47,876,000
for 1995, 1994 and 1993, respectively.
 
     The net assets of the Company's foreign operations were $29,137,000,
$24,598,000 and $17,240,000 at December 31, 1995, 1994 and 1993, respectively.
The Company's share of foreign net income was $4,763,000, $3,369,000 and
$2,843,000 in 1995, 1994 and 1993, respectively.
 
     A majority of the Company's sales are to automobile manufacturing
companies. Sales to certain major customers which exceeded 10% of consolidated
sales are as follows. Sales to one such customer amounted to 21%, 30% and 30% of
consolidated sales in 1995, 1994 and 1993, respectively. Sales to another such
customer amounted to 19%, 23% and 21% of consolidated sales in 1995, 1994 and
1993, respectively.
 
     Several other factors could have a significant impact on the continuing
operations of the Company. These factors include changes in demand for
automobiles and light trucks, relationships with significant customers, price
pressures, the timing and structure of future acquisitions or dispositions, the
integration of the Dyno acquisition into Walbro's overall business, impact of
environmental regulations, continued availability of

                   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.

Ladies and Gentlemen:

          Walbro Capital Trust (the "Trust"), a statutory business trust
created under the Business Trust Act (the "Delaware Act") of the State of
Delaware (Chapter 38, Title 12, of the Delaware Code, 12 Del. C. Section 3801 et
seq.), proposes, upon the terms and conditions set forth herein, to issue and
sell 2,000,000 [    ]% Convertible Trust Preferred Securities, liquidation
amount $25 per security (the "Firm Preferred Securities"), to the several
Underwriters named in Schedule I hereto (the "Underwriters").  The Trust also
proposes, upon the terms and conditions set forth herein and solely for the
purpose of covering over-allotments, to issue and sell to the Underwriters up to
an additional 300,000 [    ]% Convertible Trust Preferred Securities,
liquidation amount $25 per security (the "Additional Preferred Securities"). The
Firm Preferred Securities and the Additional Preferred Securities

<PAGE>   2
                                      -2-
are hereinafter collectively referred to as the "Preferred Securities."

          Each Preferred Security is convertible at the option of the holder
thereof into shares of common stock, par value $.50 per share (the "Conversion
Shares"), of Walbro Corporation (the "Company" and together with the Trust, the
"Offerors") at a conversion rate of [   ] Conversion Shares for each Preferred
Security, subject to adjustment in certain circumstances.  The Preferred
Securities will be guaranteed by the Company, to the extent set forth in the
Prospectus (as defined below), with respect to distributions and amounts payable
upon liquidation or redemption (the "Preferred Securities Guarantee") pursuant
to the Preferred Securities Guarantee Agreement (the "Preferred Securities
Guarantee Agreement") to be dated as of the Closing Date (as defined below)
executed and delivered by the Company and Bankers Trust Company (the "Guarantee
Trustee"), a New York banking corporation, not in its individual capacity
but solely as trustee, for the benefit of the holders from time to time of the
Preferred Securities.  The entire proceeds from the sale of the Preferred
Securities will be combined with the entire proceeds from the sale by the Trust
to the Company of its common securities (the "Common Securities") which will be
guaranteed by the Company, to the extent set forth in the Prospectus, with
respect to distributions and amounts payable upon liquidation or redemption (the
"Common Securities Guarantee" and, together with the Preferred Securities
Guarantee, the "Guarantees") pursuant to the Common Securities Guarantee
Agreement (the "Common Securities Guarantee Agreement" and, together with the
Preferred Securities Guarantee Agreement, the "Guarantee Agreements"), to be
dated as of the Closing Date, executed and delivered by the Company for the
benefit of the holders from time to time of the Common Securities, and will be
used by the Trust to purchase the [    ]% Convertible Subordinated Debentures
due 2017 (the "Convertible Debentures") issued by the Company.  The Preferred
Securities and the Common Securities will be issued pursuant to the Amended and
Restated Declaration of Trust of the Trust, to be dated as of Closing Date (the
"Declaration"), among the Company, as Sponsor, Bankers Trust Company, as 
institutional trustee (the "Institutional Trustee"), Bankers Trust (Delaware), 
as Delaware trustee (the "Delaware Trustee"), and Lambert E. Althaver, Daniel
L. Hittler and Michael A. Shope as regular trustees (the "Regular Trustees" 
and together with the Institutional Trustee and the Delaware Trustee, the 
"Trustees"), and the holders from time to time of undivided beneficial 
interests in the assets of the Trust.  The Convertible Debentures will be 
issued pursuant to an Indenture, to be dated
<PAGE>   3
                                      -3-





as of the Closing Date (the "Indenture"), between the Company and Bankers Trust
Company, as trustee (the "Indenture Trustee").  The Preferred Securities, the 
Preferred Securities Guarantee, the Convertible Debentures and the Conversion 
Shares are collectively referred to herein as the "Securities."  Capitalized 
terms used herein without definition have the respective meanings specified in 
the Prospectus.

          The Offerors wish to confirm as follows their agreement with you and
the other several Underwriters on whose behalf you are acting, in connection

          1.       Registration Statement and Prospectus.  The Offerors have
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,

(collectively, the "Securities Act"), a registration statement on Form S-3 (File
No. 333-18317) under the Securities Act (the "registration statement"),
including a prospectus subject to completion relating to the Securities.  The
term "Registration Statement" as used in this Agreement means the registration
statement (including all financial schedules and exhibits), as amended at the
time it becomes effective, or, if the registration statement became effective
prior to the execution of this Agreement, as supplemented or amended prior to
the execution of this Agreement.  If it is contemplated, at the time this
Agreement is executed, that a post-effective amendment to the registration
statement will be filed and must be declared effective before the offering of
the Preferred Securities may commence, the term "Registration Statement" as used
in this Agreement means the registration statement as amended by said
post-effective amendment.  If an additional registration statement is prepared
and filed with the Commission in accordance with Rule 462(b) under the
Securities Act (an "Additional Registration Statement"), the term "Registration
Statement" as used in this Agreement includes the Additional Registration
Statement.  The term "Prospectus" as used in this Agreement means the prospectus
in the form included in the Registration Statement as supplemented by the
addition of Rule 430A information contained in the prospectus filed with the
Commission pursuant to Rule 424(b) under the Securities Act.  The term
"Prepricing Prospectus" as used in this Agreement means the prospectus subject
to completion relating to the Preferred Securities in the form included in the 
registration statement at the time of the initial filing of the registration 
statement
<PAGE>   4
                                      -4-

with the Commission, and as such prospectus shall have been amended from  time
to time prior to the date of the Prospectus.  Any reference in this Agreement to
the registration statement, the Registration Statement, any Prepricing
Prospectus or the Prospectus shall be deemed to refer to and include the
documents incorporated by reference therein pursuant to Form S-3 under the
Securities Act, as of the date of the registration statement, the Registration
Statement, such Prepricing Prospectus or the Prospectus, as the case may be, and
any reference to any amendment or supplement to the registration statement, the
Registration Statement, any Prepricing Prospectus or the Prospectus shall be
deemed to refer to and include any documents filed after such date under the
Securities Exchange Act of 1934, as amended, and the rules and regulations of
the Commission thereunder (collectively, the "Exchange Act") which, upon filing,
are incorporated by reference therein, as required by Form S-3.  As used herein,
the term "Incorporated Documents" means the documents which at the time are
incorporated by reference in the registration statement, the Registration
Statement, any Prepricing Prospectus, the Prospectus, or any amendment or
supplement thereto.

          2.       Agreements to Sell and Purchase.  The Trust hereby agrees,
subject to all the terms and conditions set forth herein, to issue and sell to
each Underwriter and, upon the basis of the representations, warranties and
agreements of the Offerors herein contained and subject to all the terms and
conditions set forth herein each Underwriter agrees, severally and not jointly,
to purchase from the Trust, at a purchase price of $[     ] per Firm Preferred
Security, plus accrued distributions, if any from [          ], 1997, the number
of Firm Preferred Securities set forth opposite the name of such Underwriter in
Schedule I hereto (or such number of Firm Preferred Securities increased as set
forth in Section 10 hereof).

          The Company agrees that, in view of the fact that the proceeds of the
sale of the Preferred Securities will be invested in the Convertible Debentures,
it shall pay to the Underwriters as compensation ("Underwriters' Compensation")
for their arranging the investment of the proceeds therein, on the Closing Date,
$[         ] per Firm Preferred Security.  The Underwriters shall inform the
Company in writing on the Closing Date of the aggregate number of Firm Preferred
Securities so sold.

          The Trust also agrees, subject to all the terms and conditions set
forth herein, to sell to the Underwriters, and upon the basis of the

agreements of the Company herein contained and subject to all the terms and
conditions set forth herein, the Underwriters shall have the right to purchase
from the Trust pursuant to an option (the "over-allotment option") which may be
exercised at any one time prior to 9:00 P.M., New York City time, on the 30th
day after the date of the Prospectus (or, if such 30th day shall be a Saturday
or Sunday or a holiday, on the next business day thereafter when the NASDAQ
National Market ("NASDAQ") is open for trading), up to 300,000 Additional
Preferred Securities at the same purchase price as the Firm Preferred
Securities, plus accrued distributions, if any, from [          ], 1997.  Upon
exercise of the over-allotment option, each Underwriter, severally and not
jointly, agrees to purchase that number of Additional Preferred Securities
(subject to such adjustments as you may determine in order to avoid fractional
securities) which bears the same proportion to the aggregate number of
Additional Preferred Securities to be purchased by the Underwriters as the
number of Firm Preferred Securities set forth opposite the name of such
Underwriter bears in Schedule I hereto (or such number of Firm Preferred
Securities increased as set forth in Section 10 hereof) to the aggregate number
of Firm Preferred Securities.  The Company agrees that it will pay Underwriters'
Compensation on the Option Closing Date (as hereinafter defined) in the amounts
per Preferred Security set forth in the immediately preceding paragraph with
respect to any Additional Preferred Securities purchased by the Underwriters.

          3.       Terms of Public Offering.  The Offerors have been advised by
you that the Underwriters propose to make a public offering of their respective
portions of the Preferred Securities as soon as the Underwriters deem advisable
after the Registration Statement has become effective, this Agreement has been
executed and delivered, and the Declaration, the Preferred Securities Guarantee
Agreement and the Indenture have been qualified under the Trust Indenture Act of
1939, as amended (the "1939 Act").  The entire proceeds from the sale of the
Preferred Securities will be combined with the entire proceeds from the sale by
the Trust to the Company of its Common Securities, and will be used by the Trust
to purchase an equivalent amount of the Convertible Debentures.

          4.       Delivery of the Preferred Securities and Payment Therefor.
Delivery to the Underwriters of and payment for the  Firm Preferred Securities
shall be made at the office of Smith Barney Inc., 388 Greenwich Street, New
York, New York 10013, at 8:30 A.M., New York City time, on [ ], 1997 (the
"Closing Date").  The place of closing for the Preferred Securities
<PAGE>   6
                                      -6-

and the Closing Date may be varied by agreement between you and the Company.

          Delivery to the Underwriters of and payment for any Additional
Preferred Securities to be purchased by the Underwriters shall be made at the
aforementioned office of Smith Barney Inc. at such time and on such date (the
"Option Closing Date"), which may be the same as the Closing Date but shall in
no event be earlier than the Closing Date nor earlier than two nor later than
ten business days after the giving of the notice hereinafter referred to, as
shall be specified in a written notice from you to the Offerors of the
Underwriters' determination to purchase the number of Additional Preferred
Securities specified in such notice.  The place of closing for any Additional
Preferred Securities and the Option Closing Date for such Additional Preferred
Securities may be varied by agreement between you and the Offerors.

          The Firm Preferred Securities and any Additional Preferred Securities
which the Underwriters may elect to purchase shall be delivered to you for the
accounts of the several Underwriters registered in the name of Cede & Co., as
nominee for the Depository Trust Company, against payment of the purchase price
therefor in immediately available funds.  The Preferred Securities to be
delivered to the Underwriters shall be made available to you in New York City
for inspection and packaging not later than 9:30 A.M., New York City time, on
the business day next preceding the Closing Date or the Option Closing Date, as
the case may be.

          5.    Agreements of the Offerors.  The Company and the Trust, jointly
and severally, agree with the several Underwriters as follows:

               (a)      If, at the time this Agreement is executed and
          delivered, it is necessary for the Registration Statement or a post-
          effective amendment thereto (or any Additional Registration Statement)
          to be declared or to become effective before the offering of the
          Securities may commence, the Offerors will endeavor to cause the
          Registration Statement or such post-effective amendment to become
          effective as soon as possible and will advise you promptly and, if
          requested by you, will confirm such advice in  writing, when the
          Registration Statement or such post-effective amendment (or any
          Additional Registration Statement) has become effective.
<PAGE>   7
                                      -7-

               (b)      The Offerors will advise you promptly and, if requested
          by you, will confirm such advice in writing:  (i) of any request by
          the Commission for amendment of or a supplement to the Registration
          Statement, any Prepricing Prospectus or the Prospectus or for
          additional information; (ii) of the issuance by the Commission of any
          stop order suspending the effectiveness of the Registration Statement
          or of the suspension of qualification of the Securities for offering
          or sale in any jurisdiction or the initiation of any proceeding for
          such purpose; and (iii) within the period of time referred to in
          paragraph (f) below, of the happening of any event, which makes any
          statement of a material fact made in the Registration Statement or the
          Prospectus (as then amended or supplemented) untrue or which requires
          the making of any additions to or changes in the Registration
          Statement or the Prospectus (as then then amended or supplemented) in
          order to state a material fact required by the Securities Act or the
          regulations thereunder to be stated therein or necessary in order to
          make the statements therein not misleading, or of the necessity to
          amend or supplement the Prospectus (as then amended or supplemented)
          to comply with the Securities Act or any other law.  If at any time
          the Commission shall issue any stop order suspending the effectiveness
          of the Registration Statement, the Offerors will make every reasonable
          effort to obtain the withdrawal of such order at the earliest possible
          time.

               (c)      The Offerors will furnish to you, without charge, (i) 3
          copies of the registration statement as originally filed with the
          Commission via EDGAR and of each amendment thereto so filed, including
          financial statements and all exhibits to the registration statement,
          and will furnish you with an equal number of copies of executed
          signature pages regarding the same, (ii) such number of conformed
          copies of the registration statement as originally filed and of each
          amendment thereto, but without exhibits, as you may reasonably request
          and (iii) such number of copies of the Declaration, the Preferred
          Securities Guarantee Agreement, the Common Securities Guarantee
          Agreement and the Indenture and of the Incorporated Documents, as you
          may reasonably request.

               (d)      Prior to the end of the period of time referred to in
          the first sentence in subsection (f) below, the Offerors will not file
          any amendment to the Registration Statement or any Additional
          Registration Statement or make
<PAGE>   8
                                      -8-

     any amendment or supplement to the Prospectus to which you shall reasonably
     object or file with the Commission any document which upon filing becomes
     an Incorporated Document and of which you shall not previously have been
     advised.

          (e)      Prior to the execution and delivery of this Agreement, the
     Offerors have delivered to you, without charge, in such quantities as you
     have reasonably requested, copies of each Prepricing Prospectus.  The
     Offerors consent to the use, in accordance with the provisions of the
     Securities Act and with the securities or Blue Sky laws of the
     jurisdictions in which the Preferred Securities are offered by the several
     Underwriters and by dealers, prior to the date of the Prospectus, of each
     Prepricing Prospectus so furnished by the Offerors.

          (f)      As soon after the execution and delivery of this Agreement as
     possible and thereafter from time to time for such period as in the opinion
     of counsel for the Underwriters a Prospectus is required by the Securities
     Act to be delivered in connection with sales by any Underwriter or dealer,
     the Offerors will expeditiously deliver to each Underwriter and each
     dealer, without charge, as many copies of the Prospectus (and of any
     amendment or supplement thereto) as you may reasonably request.  The
     Offerors' consent to the use of the Prospectus (and of any amendment or
     supplement thereto) in accordance with the provisions of the Securities Act
     and with the securities or Blue Sky laws of the jurisdictions in which the
     Preferred Securities are offered by the several Underwriters and by all
     dealers to whom Preferred Securities may be sold, both in connection with
     the offering and sale of the Preferred Securities and for such period of
     time thereafter as the Prospectus is required by the Securities Act to be
     delivered in connection with sales by any Underwriter or dealer.  If during
     such period of time any event shall occur that in the judgment of the
     Offerors or in the opinion of counsel for the Underwriters is required to
     be set forth in the Prospectus (as then amended or supplemented) or should
     be set forth therein in order to make the statements therein, in the light
     of the circumstances under which they were made, not misleading, or if it
     is necessary to supplement or amend the Prospectus (or to file under the
     Exchange Act any document which upon filing, becomes an Incorporated
     Document) in order to comply with the Securities Act or any other law, the
     Offerors will forthwith prepare and, subject to the provisions of
<PAGE>   9
                                      -9-

     paragraph (d) above, file with the Commission an appropriate supplement or
     amendment thereto (or to such document), and will expeditiously furnish to
     the Underwriters and dealers a reasonable number of copies thereof.  In the
     event that the Offerors and you, as Representatives of the several
     Underwriters, agree that the Prospectus should be amended or supplemented,
     the Offerors or the Company, if requested by you, will promptly issue a
     press release announcing or disclosing the matters to be covered by the
     proposed amendment or supplement.

          (g)      The Offerors will cooperate with you and with counsel for the
     Underwriters in connection with the registration or qualification of the
     Securities for offering and sale by the several Underwriters and by dealers
     under the securities or Blue Sky Laws of such jurisdictions as you may
     designate and will file such consents to service of process or other
     documents necessary or appropriate in order to effect such registration or
     qualification; provided that in no event shall the Company or the Trust be
     obligated to qualify to do business in any jurisdiction where it is not now
     so qualified or to take any action which would subject it to taxation or
     service of process in suits, other than those arising out of the offering
     or sale of the Preferred Securities, in any jurisdiction where it is not
     now so subject.

          (h)      The Offerors will make generally available to the Trust's
     security holders a consolidated earnings statement of the Company, which
     need not be audited, covering a twelve-month period commencing after the
     effective date of the Registration Statement and ending not later than 15
     months thereafter, as soon as practicable after the end of such period,
     which consolidated earnings statement shall satisfy the provisions of
     Section 11(a) of the Securities Act.

          (i)      So long as any of the Securities are outstanding, the Company
     will furnish to you, (i) as soon  as available, a copy of all reports and
     other communications (financial or otherwise) of the Company mailed to
     stockholders or filed by the Company with the Commission or any national
     securities exchange on which any security of the Company may be listed or
     quoted and a copy of each Annual Report on Form 10-K, each quarterly report
     on Form 10-Q and each current report on Form 8-K filed by the Company with
     the Commission under the Exchange Act, and (ii) from time to
<PAGE>   10
                                      -10-

     time such other information concerning the Company as you may reasonably
     request and the Trust will furnish to you, upon your request, a copy of
     each report of the Trust mailed to holders of Preferred Securities or
     Common Securities.

          (j)      If this Agreement shall terminate or shall be terminated
     after execution pursuant to any provisions hereof (otherwise than pursuant
     to the second paragraph of Section 10 hereof or by notice given by you
     terminating this Agreement pursuant to Section 10 hereof) or if this
     Agreement shall be terminated by the Underwriters because of any failure or
     refusal on the part of the Offerors to comply with the terms or fulfill any
     of the conditions of this Agreement, the Company agrees to reimburse the
     Underwriters for all reasonable out-of-pocket expenses (including
     reasonable fees and expenses of counsel for the Underwriters) incurred by
     you in connection herewith.

          (k)      The Trust will apply the net proceeds from the sale of the
     Preferred Securities, and the Company will apply the net proceeds from the
     sale of the Convertible Debentures, substantially in accordance with the
     description set forth in the Prospectus under "Use of Proceeds".

          (l)      If required by the rules of the Commission, the Offerors 
     will timely file the Prospectus pursuant to Rule 424(b) under the 
     Securities Act and will advise you of the time and manner of such filing.

          (m)      Each of the Trust and the Company agree, during the period
     beginning on the date of this Agreement and continuing to and including the
     date that is 90 days after the Closing Date, not to offer, sell,
     contract to offer, sell or otherwise dispose of any preferred securities,
     any preferred stock, any common stock or any other securities (including
     any backup undertakings for 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.

          (n)      Except as stated in this Agreement and in the Prepricing
     Prospectus and Prospectus, the Company has not

<PAGE>   11
                                      -11-


     taken, nor will it take, directly or indirectly, any action designed to or
     that might reasonably be expected to cause or result in stabilization or
     manipulation of the price of the Preferred Securities to facilitate the
     sale or resale of the Preferred Securities.

          (o)      The Company will use its best efforts to effect the quotation
     of the Preferred Securities on the NASDAQ.  If the Convertible Debentures
     are distributed on the occurrence of a Tax Event (as defined in the
     Prospectus), the Company will use its best efforts to effect the quotation
     of such Convertible Debentures on the NASDAQ or such other exchange where
     the Preferred Securities are listed.

          6.       Representations and Warranties of the Offerors.  The Company
and the Trust, jointly and severally, represent and warrant to, and agree with,
each Underwriter that as of the date hereof, as of the Closing Date referred to
in Section 4 hereof, and as of each Option Closing Date if any, as referred to
in Section 4 hereof:

          (a)      Each Prepricing Prospectus complied in all material respects
     with the provisions of the Securities Act.  The Commission has not issued
     any order preventing or suspending the use of any Prepricing Prospectus.

          (b)      Each of the Offerors and the transactions contemplated by
     this Agreement meet the requirements for using Form S-3 under the
     Securities Act.  The registration statement in the form in which it became
     or becomes effective and also in such form as it may be when any
     post-effective amendment thereto shall become effective, any Additional
     Registration statement when filed with the Commission pursuant to Rule
     462(b) under the Securities Act and the Prospectus and any supplement and
     amendment thereto when filed with the Commission under Rule 424(b) under
     the Securities Act complied or will comply in all material respects with
     the provisions of the Securities  Act and will not at any such times
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, except that this representation and warranty does
     not apply to statements in or omissions from the registration statement or
     the Prospectus made in reliance upon and in conformity with


<PAGE>   12
                                      -12-


     information relating to any Underwriter furnished to the Offerors in
     writing by or on behalf of any Underwriter through you expressly for use
     therein.

          (c)      The Incorporated Documents heretofore filed, when they were
     filed (or, if any amendment with respect to any such document was filed,
     when such amendment was filed), conformed in all material respects with the
     requirements of the Exchange Act and the rules and regulations thereunder,
     any further Incorporated Documents so filed will, when they are filed,
     conform in all material respects with the requirements of the Exchange Act
     and the rules and regulations thereunder; no such document when it was
     filed (or, if an amendment with respect to any such document was filed,
     when such amendment was filed), contained an untrue statement of a material
     fact or omitted to state a material fact required to be stated therein or
     necessary in order to make the statements therein not misleading; and no
     such further document, when it is filed, will contain an untrue statement
     of a material fact or will omit to state a material fact required to be
     stated therein or necessary in order to make the statements therein not
     misleading.

          (d)      The execution and delivery of, and the performance by the
     Company and the Trust of their respective obligations under this Agreement
     have been duly and validly authorized by the Company and the Trust,
     respectively, and this Agreement has been duly executed and delivered by
     the Company and the Trust, respectively, and is enforceable in accordance
     with its terms, except as the enforcement thereof may be limited by
     bankruptcy, insolvency (including, without limitation, all laws relating to
     fraudulent transfers), reorganization, moratorium or other similar laws
     affecting enforcement of creditors' rights generally and subject to the
     applicability of general principles of equity and except as rights 
     to indemnity hereunder may be limited by federal securities laws.

          (e)      The Offerors have not distributed and, prior to the later to
     occur of (i) the Closing Date and (ii) completion of the distribution of
     the Preferred Securities, will not distribute any offering materials in
     connection with the offering and sale of the Preferred Securities other
     than the Registration Statement, the Prepricing Prospectus, the Prospectus
     or other materials, if any, permitted by the Securities Act.

     financial statements and supporting schedules of the Company, Dyno and

     regulations.

          (g)      The financial statements included in the Registration

     generally accepted accounting principles ("GAAP") applied on a consistent
     basis throughout the periods involved.  The supporting schedules, if any,
     included in the Registration Statement present fairly in accordance with
     GAAP the information required to be stated therein.  The selected financial
     data and the summary financial information included in the Prospectus
     present fairly the information shown therein and have been compiled on a
     basis consistent with that of the audited financial statements included in
     the Registration Statement.

          (h)      Since the respective dates as of which information is given
     in the Registration Statement and the Prospectus, except as otherwise
     stated therein, (A) there has been no material adverse change in the
     condition, financial or otherwise, or in the earnings, business affairs or

     "Material Adverse Effect") and (B) there have been no transactions entered

     no dividend or distribution of any kind declared, paid or made by the
     Company on any class of its capital stock except as is described in the

     existing as a corporation in good standing under the laws of the state of

     under this Agreement, the Declaration, the Indenture, the Guarantees and
     the Convertible Debentures and to purchase, own and hold the Common
     Securities issued by the Trust; and the Company is duly registered and
     qualified as a foreign corporation to conduct its business and is in good
     standing in each other jurisdiction in which such qualification is
     required, whether by reason of the ownership or leasing of property or the
     conduct of business, except where the failure so to qualify or to be in
     good standing would not result in a Material Adverse Effect.

          (j)      Each Significant Subsidiary of the Company as defined in 
     Rule 1-02 of Regulation S-X under the Securities Act (a "Significant
     Subsidiary") has been duly incorporated and is validly existing as a 
     corporation in good standing under the laws of the jurisdiction of its

     operate its properties and to conduct its business as described in the
     Registration Statement and the Prospectus and is duly registered and
     qualified as a foreign corporation to transact business and is in good

     conduct of its business requires such registration or qualification,
     except where the failure so to qualify or to be in good standing would not
     result in a Material Adverse Effect; except as otherwise disclosed in the
     Registration Statement and the Prospectus, all of the issued and
     outstanding capital stock of each such Significant Subsidiary has been 
     duly authorized and validly issued, is fully paid and non-assessable
     and is owned by the Company, directly or through subsidiaries, free and
     clear of any security interest, mortgage pledge, lien, encumbrance, claim
     or equity; none of the outstanding shares of capital stock of any
     subsidiary was issued in violation of the preemptive or similar rights of
     any securityholder of such subsidiary.  The only Significant Subsidiaries
     of the Company are the subsidiaries listed in Schedule II hereto.

          (k)      The authorized, issued and outstanding capital stock of the
     Company is as set forth in the Prospectus as of the respective dates
     presented; and the Preferred Securities, the Common Securities, the
     Conversion Shares, the Convertible Debentures, the Declaration, the
     Preferred Securities Guarantee Agreement and the Indenture conform in all
     material respects to

     of the Preferred Securities," "Description of the Guarantee," "Description
     of the Convertible Debentures," "Effect of Obligations Under the
     Convertible Debentures and the Guarantee" and "Description of Capital
     Stock".

          (l)      The Trust has been duly created and is validly existing in
     good standing as a business trust under the Delaware Act with the power and
     authority to own property and to conduct its business as described in the
     Registration Statement and the Prospectus, and any amendment or supplement
     thereto, and to enter into and perform its obligations under this
     Agreement, the Preferred Securities, the Common Securities and the
     Declaration; the Trust is duly qualified to transact business as a foreign
     corporation in good standing in each jurisdiction in which such
     qualification is necessary, except to the extent that the failure to so
     qualify would not have a Material Adverse Effect on the Trust; and the
     Trust is not a party to or otherwise bound by any agreement other than
     those described in the Prospectus, and any amendment or supplement thereto.
     
          (m)      The Common Securities have been duly authorized by the
     Declaration and, when issued and delivered by the Trust to the Company in
     accordance with the terms of the Declaration and against payment therefor
     as described in the Prospectus, will be validly issued and (subject to the
     terms of the Declaration) fully paid and nonassessable undivided beneficial

     subleases mentioned above, or affecting or questioning the rights of the
     Company or such Significant Subsidiaries to the continued possession of

     any Environmental Law against the Company or any of its Significant
     Subsidiaries and (D) there are no events or circumstances to the knowledge

     deficiency which has been or is reasonably likely to be asserted against

          7.       Indemnification and Contribution.  (a)  Each of the Trust and
the Company, jointly and severally, agrees to indemnify and hold harmless each
of you and each other Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation) arising
out of or based upon any untruestatement or alleged untrue statement of a
material fact contained in any Prepricing Prospectus or in the Registration
Statement or the Prospectus or in any amendment or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages,
liabilities or expenses arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which has been made therein or
omitted therefrom in reliance upon and in conformity with the information
relating to such reliance upon and in conformity with the information relating
to such Underwriter furnished in writing to the Offerors by or on behalf of any
Underwriter through you expressly for use in connection therewith; provided,
however, that the indemnification contained in this paragraph (a) with respect
to any Prepricing Prospectus shall not inure to the benefit of any Underwriter
(or to the benefit of any person controlling such Underwriter) to the extent
that any such loss, claim, damage, liability or expense arises from the sale of
the Preferred Securities by such Underwriter to any person if it shall be
established that a copy of the Prospectus shall not have been delivered or sent
to such person within the  time 

<PAGE>   25
                                      -25-

required by the Securities Act and the regulations thereunder, and the untrue
statement or alleged untrue statement or omission or alleged omission of a
material fact contained in such Prepricing Prospectus was corrected in the
Prospectus and such correction would have cured the defect giving rise to such
loss, claim, damage, liability or expense, provided that the Offerors have
delivered the Prospectus to the several Underwriters in such quantity as the
Underwriters reasonably request on a timely basis to permit such delivery or 
sending. The foregoing indemnity agreement shall be in addition to any 
liability which the Trust or the Company may otherwise have.

          (b)      If any action, suit or proceeding shall be brought against
any Underwriter or any person controlling any Underwriter in respect of which
indemnity may be sought against the Trust or the Company, such underwriter or
such controlling person shall promptly notify the Trust and the Company, and the
Trust or the Company shall assume the defense thereof, including the employment
of counsel and payment of all fees and expenses.  Such Underwriter or any such
controlling person shall have the right to employ separate counsel in any such
action, suit or proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Underwriter or
such controlling person unless (i) the Trust or the Company has agreed in
writing to pay such fees and expenses, (ii) the Trust or the Company has failed
to assume the defense and employ counsel, or (iii) the named parties to any such
action, suit or proceeding (including any impleaded parties) include both such
Underwriter or such controlling person and the Trust or the Company, and such
Underwriter or such controlling person shall have been advised by its counsel
that representation of such indemnified party and the Trust or the Company by
thesame counsel would be inappropriate under applicable standards of
professional conduct (whether or not such representation by the same counsel has
been proposed) due to actual or potential differing interests between them (in
which case the Trust or the Company shall not have the right to assume the
defense of such action, suit or proceeding on behalf of such Underwriter or such
controlling person).  It is understood, however, that the Trust and the Company
together shall, in connection with any one such action, suit or proceeding or
separate but substantially similar or related actions, suits or proceedings in
the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of only one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Underwriters and  controlling persons 

<PAGE>   26
                                      -26-

not having actual or potential differing interests with you or among themselves,
which firm shall be designated in writing by Smith Barney Inc., and that all
such fees and expenses shall be reimbursed as they are incurred.  The Trust and
the Company shall not be liable for any settlement of any such action, suit or
proceeding effected without the Company's written consent, but if settled with
such written consent, or if there be a final judgment for the plaintiff in any
such action, suit or proceeding, the Trust and the Company agree to indemnify
and hold harmless any Underwriter, to the extent provided in the preceding
paragraph, and any such controlling person from and against any loss, claim,
damage, liability or expense by reason of such settlement or judgment.

          (c)      Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Trust, the Company, the Company's directors,
the Company's officers and the Regular Trustees who sign the Registration
Statement, and any person who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same
extent as the foregoing indemnity from the Trust and the Company to each
Underwriter, but only with respect to information relating to such Underwriter
furnished in writing by or on behalf of such Underwriter through you expressly
for use in the Registration Statement, the Prospectus or any Prepricing
Prospectus, or any amendment or supplement thereto.  If any action, suit or
proceeding shall be brought against the Trust, the Company, any of the
Company's directors, any such officer or Regular Trustee, or any such
controlling person, based on the  Registration Statement, the Prospectus or any
Prepricing Prospectus, or any amendment or supplement thereto, and in respect
of which indemnity may be sought against any Underwriter pursuant to this
paragraph (c), such Underwriter shall have the rights and duties given to the
Trust or the Company by paragraph (b) above (except that if the Trust or the
Company shall have assumed the defense thereof, such Underwriter shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Underwriter's expense), Regular Trustee and the Trust, the Company, the
Company's directors, any such officer or trustee, and any such controlling
person shall have the rights and duties given to the Underwriters by paragraph
(b) above.  The foregoing indemnity agreement shall be in addition to any
liability which the Underwriters may otherwise have.

          (d)      If the indemnification provided for in this Section 7 is
unavailable to an indemnified party under
<PAGE>   27
                                      -27-

paragraphs (a) or (c) hereof in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then an indemnifying party, in lieu
of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or expenses (i) in such proportion as is appropriate to reflect the
relative benefits received by the Trust and the Company on the one hand and the
Underwriters on the other hand from the offering of the Preferred Securities, or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Trust and the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Trust and the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Trust bear to the total compensation 
received by the Underwriters, in each case as set forth in the table on the 
cover page of the Prospectus.  The relative fault of the Trust and the 
Company on the one hand and the Underwriters on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Offerors on the one hand
or by the Underwriters on the other hand and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          (e)      The Trust, the Company and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 7 were
determined by a pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to in paragraph (d) above.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities and expenses referred to in paragraph (d) above
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating any claim or defending any such action, suit or
proceeding.  Notwithstanding the provisions of this Section 7, no Underwriter
shall be

<PAGE>   28
                                      -28-

required to contribute any amount in excess of the amount by which the total
price ofthe Preferred Securities underwritten by it and distributed to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations to contribute pursuant to this
Section 7 are several in proportion to the respective numbers of Preferred
Securities set forth opposite their names in Schedule I hereto (or such numbers
of Preferred Securities increased as set forth in Section 10 hereof) and not
joint.

          (f)      No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement, compromise or consent
relating to any pending or threatened action, suit or proceeding in respect of
which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement,
compromise or consent (i) includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such action,
suit or proceeding and (ii) does not include a statement as to or an admission
of fault or culpability by or on behalf of any indemnified party.

          (g)      Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 7 shall be paid by the indemnifying party to the indemnified party
as such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Trust and the Company set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Trust, the Company, the Company's directors or
officers, the Regular Trustees, or any person controlling the Company, (ii)
acceptance of any Preferred Securities and payment therefor hereunder, and (iii)
any termination of this Agreement.  A successor to any  Underwriter or any
person controlling any Underwriter, or to the Trust, the Company, the Company's
directors or officers, the Regular Trustees, or any person controlling the
Company, shall be entitled to the
<PAGE>   29
                                      -29-


benefits of the indemnity, contribution, and reimbursement agreements contained
in this Section 7.

          8.       Conditions of Underwriters' Obligations.  The obligations of
the several Underwriters to purchase and pay for the Preferred Securities as

          10.      Effective Date of Agreement.  This Agreement shall become
effective:  (i) upon the execution and delivery hereof by the parties hereto; or
(ii) if, at the time this Agreement isexecuted and delivered, it is necessary
for the registration statement or a post- effective amendment thereto or an
Additional Registration Statement to be declared effective before the offering
of the Preferred Securities may commence, when notification of the effectiveness
of the registration statement or such post-effective amendment has been released

<PAGE>   34
                                      -34-


notifying you, or by you, as Representatives of the several Underwriters, by
notifying the Offerors.

          If any one or more of the Underwriters shall fail or refuse to
purchase Firm Preferred Securities which it or they are obligated to purchase
hereunder, and the aggregate number of Firm Preferred Securities which such
defaulting Underwriter or Underwriters are obligated but fail or refuse to
purchase is not more than one-tenth of the aggregate number of the Firm
Preferred Securities, each non- defaulting Underwriter shall be obligated,
severally, in the proportion which the number of Firm Preferred Securities set
forth opposite its name in Schedule I hereto bears to the aggregate number of
Firm Preferred Securities set forth opposite the names of all non-defaulting
Underwriters, to purchase the Firm Preferred Securities which such defaulting
Underwriter or Underwriters are obligated, but fail or refuse, to purchase.  If
any Underwriter or Underwriters shall fail or refuse to purchase Firm Preferred
Securities and the aggregate number of Firm Preferred Securities with respect to
which such default occurs is more than one-tenth of the aggregate number of the
Firm Preferred Securities and arrangements satisfactory to you and the Offerors
for the purchase of such Firm Preferred Securities by one or more non-defaulting
Underwriters or other party or parties approved by you and the Offerors are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Offerors.  In any
such case which does not result in termination of this Agreement, either you or
the Offerors shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected.  Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any such default of any such
Underwriter under this Agreement.  The term "Underwriter" as used in this
Agreement includes, for all purposes of this Agreement, any party not listed in
Schedule I hereto, who, with your approval and the approval of the Offerors,
purchases Firm Preferred Securities which a defaulting Underwriter is obligated,
but fails or refuses, to purchase.

          Any notice under this Section 10 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

                                      -35-


          11.      Termination of Agreement.  This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Underwriter to the Offerors, by notice to the Offerors, if prior to the Closing
Date or any Option Closing Date (if different from the Closing Date and then
only as to the Additional Preferred Securities) there shall have occurred:  (i)
any suspension or limitation of trading in securities generally on the New York
Stock Exchange, the American Stock Exchange or the NASDAQ National Market, or
any setting of minimum prices for trading on any such exchange, or any
suspension of trading of any securities of the Company on any exchange or in the
over-the-counter market; (ii) any banking moratorium declared by Federal or New
York authorities; or (iii) any outbreak or escalation of hostilities or other
international or domestic calamity, crisis or change in political, financial or
economic conditions, the effect of which on the financial markets of the United
States is such as to make it, in your judgment, impracticable or inadvisable to
commence or continue the offering of the Preferred Securities on the terms set
forth on the cover page of the Prospectus or to enforce contracts for the resale
of the Preferred Securities by the Underwriters.  Notice of such termination may
be given to the Company by telegram, telecopy or telephone and shall be
subsequently confirmed by letter.

set forth in the last paragraph on the cover page, the stabilization legend on

Preferred Securities and its consequences, provided that, if the underlying
Event of Default under the Indenture:

                    (i)    is not waivable under the Indenture, the Event of
         Default under the Declaration shall also not be waivable; or



<PAGE>   19
                                      -12-



                   (ii) requires the consent or vote of greater than a majority
         in principal amount of the holders of the Debentures (a "Super
         Majority") to be waived under the Indenture, the Event of Default under

         least the proportion in liquidation amount of the Preferred Securities
         that the relevant Super Majority represents of the aggregate principal
         amount of the Debentures outstanding.

lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act. Upon
such waiver, any such default shall cease to exist, and any Event of Default
with respect to the Preferred Securities arising therefrom shall be deemed to
have been cured, for every purpose of this Declaration, but no such waiver shall
extend to any subsequent or other default or an Event of Default with respect to
the Preferred Securities or impair any right consequent thereon. Any waiver by
the Holders of the Preferred Securities of an Event of Default with respect to
the Preferred Securities shall also be deemed to constitute a waiver by the
Holders of the Common Securities of any such Event of Default with respect to
the Common Securities for all purposes of this Declaration without any further
act, vote, or consent of the Holders of the Common Securities.

                  (b) The Holders of a majority in liquidation amount of the
Common Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                    (i) is not waivable under the Indenture, except where the
         Holders of the Common Securities are deemed to have waived such Event
         of Default under the Declaration as provided below in this Section
         2.6(b), the Event of Default under the Declaration shall also not be
         waivable; or

                   (ii) requires the consent or vote of a Super Majority to be
         waived, except where the Holders of the Common Securities are deemed to
         have waived such Event of Default under the Declaration as provided
         below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the 
<PAGE>   20
                                      -13-



         proportion in liquidation amount of the Common Securities that the
         relevant Super Majority represents of the aggregate principal amount of
         the Debentures outstanding;

provided further, that each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated, and
until such Events of Default 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 in accordance
with the terms of the Securities. The foregoing provisions of this Section
2.6(b) shall be in lieu of Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act and such Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust
Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Subject to the foregoing
provisions of this Section 2.6(b), upon such waiver, any such default shall
cease to exist and any Event of Default with respect to the Common Securities
arising therefrom shall be deemed to have been cured for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

                  (c) A waiver of an Event of Default under the Indenture by the
Institutional Trustee at the direction of the Holders of the Preferred
Securities constitutes a waiver of the corresponding Event of Default under this
Declaration. The foregoing provisions of this Section 2.6(c) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Declaration and
the Securities, as permitted by the Trust Indenture Act.

SECTION 2.7 Event of Default; Notice.

                  (a) The Institutional Trustee shall, within 90 days after the
occurrence of an Event of Default, transmit by mail, first class postage
prepaid, to the Holders of the Securities, notices of all defaults with respect
to the Securities actually known to a Responsible Officer of the Institutional
Trustee, unless such defaults have been cured before the giving of such notice
(the term "defaults" for the purposes of this Section 2.7(a) being hereby
defined to be an Event of Default as

therein and irrespective of the giving of any notice provided therein); provided
that, except for a default in the payment of principal of (or premium, if any)
or interest on any of the Debentures or in the payment of any sinking fund
installment established for the Debentures, the Institutional Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors and/or Responsible
Officers of the Institutional Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of the Securities.

                  (b)      The Institutional Trustee shall not be deemed to
have knowledge of any default except:

                    (i)    a default under Sections [501(1) and 501(2)] of
         the Indenture; or

                   (ii) any default as to which the Institutional Trustee shall
         have received written notice or of which a Responsible Officer of the
         Institutional Trustee charged with the administration of the
         Declaration shall have actual knowledge.

Act, or (ii) for United States federal income tax purposes the Trust will not be
classified as a grantor trust.

         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 Sponsor guarantees the obligations of such Successor
         Entity under the Successor Securities at least to the extent provided
         by the Preferred Securities Guarantee; and

                 (viii) prior to such merger, consolidation, amalgamation or
         replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust reasonably acceptable to
         the Institutional Trustee 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 Securities (including any
                  Successor Securities) in any material respect (other than with
                  respect to any dilution of the Holders' interest in the new
                  entity);

                           (B) following such merger, consolidation,
                  amalgamation or replacement, neither the Trust nor the
                  Successor Entity will be required to register as an Investment
                  Company; and

                           (C) following such merger, consolidation,
                  amalgamation or replacement, the Trust (or the Successor
                  Entity) will be treated as a grantor trust for United States
                  federal income tax purposes.

                  (c) Notwithstanding Section 3.9(b), the Trust shall not,
except with the consent of Holders of 100% in liquidation amount of the Common
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 Successor Entity to be classified
as other than a grantor trust for United States federal income tax purposes.

resignation shall take effect upon such delivery or upon such later date as is
specified therein; provided, however, that:

                    (i) No such resignation of the Trustee that acts as the

                  (e) The Holders of the Common Securities shall use their best
efforts to promptly appoint a Successor Institutional Trustee or Successor
Delaware Trustee, as the case may be, if the Institutional Trustee or the

Delaware Trustee shall have been appointed and accepted appointment as provided

                  If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Regular Trustees or,
if there are more than two, a majority of the Regular Trustees, shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.6

                  The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to annul the Trust. Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the appointment
of a Regular Trustee in accordance with this Section 5.6, the Regular Trustees
in office, regardless of their number, shall have all the powers granted to the
Regular Trustees and shall discharge all the duties imposed upon the Regular
Trustees by this Declaration.

                  (a) Subject to the limitations provided in this Declaration
and to the specific duties of the Institutional Trustee, the Regular Trustees
shall have exclusive and complete authority to carry out the purposes of the
Trust. An action taken by the Regular Trustees in accordance with their powers

except if a meeting of the Regular Trustees is called with respect to any matter
over which the Regular Trustees have power to act, any power of the Regular

of the Holders of the Securities. The right, title and interest of the
Institutional Trustee to the Debentures shall vest automatically in each Person
who may hereafter be appointed as Institutional Trustee in accordance with

                    (i) establish and maintain a segregated non-interest bearing

         make payments to the Holders of the Preferred Securities and Holders of
         the Common Securities from the Institutional Trustee Account in
         accordance with Section 6.1. Funds in the Institutional Trustee Account
         shall be held uninvested until disbursed in accordance with this
         Declaration. The Institutional Trustee Account shall be an account that
         is maintained with the Institutional Trustee or a banking institution

         to the rating assigned to the Preferred Securities by a "nationally
         recognized statistical rating organization," as that term is defined
         for purposes of Rule 436(g)(2) under the Securities Act;

                   (ii) engage in such ministerial activities as so directed and
         as shall be necessary or appropriate to effect the redemption of the
         Preferred Securities and the Common Securities to the extent the
         Debentures are redeemed or mature; and

                  (iii) upon written notice of distribution issued by the
         Regular Trustees in accordance with the terms of the 



<PAGE>   39
                                      -32-



         Securities, engage in such ministerial activities as so directed as
         shall be necessary or appropriate to effect the distribution of the
         Debentures to Holders of Securities upon the occurrence of certain
         Special Events pursuant to the terms of the Securities.

                  (d) The Institutional Trustee shall take all actions and
perform such duties as may be specifically required of the Institutional Trustee
pursuant to the terms of the Securities.

                  (e) The Institutional Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, if an Event of Default actually known to a Responsible
Officer of the Institutional Trustee occurs and is continuing, the Institutional
Trustee shall, for the benefit of Holders of the Securities, but subject to the
rights of the Holders pursuant to the terms of such Securities, enforce its
rights as holder of the Debentures, including the right to take any Legal Action
which arises out of or in connection with such an Event of Default.

                  (f) Subject to this Section 5.11, the Institutional Trustee
shall have none of the duties, liabilities, powers or the authority of the
Regular Trustees set forth in Section 5.9.

                  (g) The Institutional Trustee must exercise the powers set
forth in this Section 5.11 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Institutional Trustee
shall not take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3

SECTION  5.12 Certain Duties and Responsibilities of the Institutional Trustee.

                  (a) The Institutional Trustee, before the occurrence of any
Event of Default and after the curing or waiving of all Events of Default that
may have occurred, shall undertake to perform only such duties and obligations
as are specifically set forth in this Declaration and no implied covenants shall
be read into this Declaration against the Institutional Trustee. In case an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6) of which a Responsible Officer of the Institutional Trustee has
actual knowledge, the Institutional Trustee shall exercise such rights and
powers vested in it by this Declaration, and use the same degree of care and
skill in its exercise, as a prudent individual would 



<PAGE>   40
                                      -33-



exercise or use under the circumstances in the conduct of his or her own
affairs.

                  (b) No provision of this Declaration shall be construed to
relieve the Institutional Trustee from liability for its own negligent action,
its own negligent failure to act, or its own willful misconduct, except that
prior to the occurrence of an Event of Default and after the curing or waiving
of all such Events of Default that may have occurred, in the absence of bad
faith on the part of the Institutional Trustee, the Institutional Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon any certificates or opinions furnished to the
Institutional Trustee and conforming to the requirements of this Declaration;
but in the case of any such certificates or opinions that by any provision
hereof are specifically required to be furnished to the Institutional Trustee,
the Institutional Trustee shall be under a duty to examine the same to determine
whether or not they conform to the requirements of this Declaration.

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

                  (d) The Institutional Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance
with the direction of the Holders of not less than a majority in liquidation
amount of the Securities relating to the time, method and place of conducting
any proceeding for any remedy available to the Institutional Trustee, or
exercising any trust or power conferred upon the Institutional Trustee under
this Declaration.

                  (e) The Institutional Trustee shall not be responsible for
monitoring the compliance by the Regular Trustees or the Sponsor with their
respective duties under this Declaration, nor shall the Institutional Trustee be
liable for any default or misconduct of the Regular Trustees or the Sponsor.

                  (f) No provision of this Declaration shall require the
Institutional Trustee to expend or risk its own funds or otherwise incur
personal financial liability in the performance of any of its duties or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that the repayment of such funds or liability is not reasonably



<PAGE>   41
                                      -34-



assured to it under the terms of this Declaration or indemnity reasonably
satisfactory to the Institutional Trustee against such risk or liability is not
reasonably assured to it.

                  (g) The Institutional Trustee's sole duty with respect to the
custody, safe keeping and physical preservation of the Debentures and the
Institutional Trustee Account shall be to deal with such property in a similar
manner as the Institutional Trustee deals with similar property for its own
account, subject to the protections and limitations on liability afforded to the
Institutional Trustee under this Declaration and the Trust Indenture Act.

                  (h) The Institutional Trustee shall not be liable for any
interest on any money received by it except as it may otherwise agree in writing
with the Sponsor. Money held by the Institutional Trustee need not be segregated
from other funds held by it except in relation to the Institutional Trustee
Account maintained by the Institutional Trustee pursuant to Section 5.11(c)(i)
and except to the extent otherwise required by law.

                  (i) The Institutional Trustee shall have no duty or liability
for or with respect to the value, genuineness, existence or sufficiency of the
Debentures or the payment of any taxes or assessments levied thereon or in
connection therewith.

                  (a) Subject to the provisions of Section 5.12:

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

                   (ii) any direction or act of the Sponsor or the Regular
         Trustees contemplated by this Declaration shall be
         sufficiently evidenced by an Officers Certificate;

                  (iii) whenever in the administration of this Declaration, the
         Institutional Trustee shall deem it desirable that a matter be proved
         or established 


<PAGE>   42
                                      -35-



         before taking, suffering or omitting any action hereunder, the
         Institutional Trustee (unless other evidence is herein specifically
         prescribed) may, in the absence of bad faith on its part, request and
         rely upon an Officers' Certificate which, upon receipt of such request,
         shall be promptly delivered by the Sponsor or the Regular Trustees;

                   (iv) the Institutional Trustee shall have no duty to see to
         any recording, filing or registration of any instrument (including any
         financing or continuation statement or any filing under tax or
         securities laws) or any rerecording, refiling or registration thereof;

                    (v) the Institutional Trustee may consult with counsel of
         its choice or other experts and the advice or opinion of such counsel
         and experts with respect to legal matters or advice within the scope of
         such experts' area of expertise shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in accordance with such
         advice or opinion, such counsel may be counsel to the Sponsor or any of
         its Affiliates, and may include any of its employees. The Institutional
         Trustee shall have the right at any time to seek instructions
         concerning the administration of this Declaration from any court of
         competent jurisdiction;

                   (vi) the Institutional Trustee shall be under no obligation
         to exercise any of the rights or powers vested in it by this
         Declaration at the request or direction of any Holder, unless such
         Holder shall have provided to the Institutional Trustee adequate
         security and indemnity, reasonably satisfactory to the Institutional
         Trustee, against the costs, expenses (including attorneys' fees and
         expenses and the expenses of the Institutional Trustee's agents,
         nominees or custodians) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Institutional Trustee; provided
         that, nothing contained in this Section 5.13(a)(vi) shall be taken to
         relieve the Institutional Trustee, upon the occurrence of an Event of
         Default, of its obligation to exercise the rights and powers vested in
         it by this Declaration;
<PAGE>   43
                                      -36-



                  (vii) the Institutional Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, security, bond, debenture, note, other
         evidence of indebtedness or other paper or document, but the
         Institutional Trustee, in its discretion, may make such further inquiry
         or investigation into such facts or matters as it may see fit;

                 (viii) the Institutional Trustee may execute any of the trusts
         or powers hereunder or perform any duties hereunder either directly or
         by or through agents or attorneys and the Institutional Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         agent or attorney appointed with due care by it hereunder;

                   (ix) any action taken by the Institutional Trustee or its
         agents hereunder shall bind the Trust and the Holders of the
         Securities, and the signature of the Institutional Trustee or its
         agents alone shall be sufficient and effective to perform any such
         action and no third party shall be required to inquire as to the
         authority of the Institutional Trustee to so act or as to its
         compliance with any of the terms and provisions of this Declaration,
         both of which shall be conclusively evidenced by the Institutional
         Trustee's or its agent's taking such action;

                    (x) whenever in the administration of this Declaration the
         Institutional Trustee shall deem it desirable to receive instructions
         with respect to enforcing any remedy or right or taking any other
         action hereunder, the Institutional Trustee (A) may request
         instructions from the Holders of the Securities, which instructions may
         only be given by the Holders of the same proportion in liquidation
         amount of the Securities as would be entitled to direct the
         Institutional Trustee under the terms of the Securities in respect of
         such remedy, right or action, (B) may refrain from enforcing such
         remedy or right or taking such other action until such instructions are
         received, and (C) shall be protected in acting in accordance with such
         instructions;

                   (xi)    except as otherwise expressly provided by this
         Declaration, the Institutional Trustee shall not 



<PAGE>   44

                                      -37-



         be under any obligation to take any action that is discretionary under
         the provisions of this Declaration; and

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

                  (b) No provision of this Declaration shall be deemed to impose
any duty or obligation on the Institutional Trustee to perform any act or acts
or exercise any right, power, duty or obligation conferred or imposed on it, in
any jurisdiction in which it shall be illegal, or in which the Institutional
Trustee shall be unqualified or incompetent in accordance with applicable law,
to perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Institutional
Trustee shall be construed to be a duty.

SECTION 5.14 Delaware Trustee.

                  Notwithstanding any other provision of this Declaration other
than Section 5.2, the Delaware Trustee shall not be entitled to exercise any
powers, nor shall the Delaware Trustee have any of the duties and
responsibilities of the Regular Trustees or the Institutional Trustee described
in this Declaration. Except as set forth in Section 5.2, the Delaware Trustee
shall be a Trustee for the sole and limited purpose of fulfilling the
requirements of Section 3807 of the Business Trust Act.

SECTION 5.15  Meetings.

                  If there is more than one Regular Trustee, meetings of the

Trustee. Regular meetings of the Regular Trustees may be held at a time and
place fixed by resolution of the Regular Trustees. Notice of any in-person
meetings of the Regular Trustees shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 48 hours before such meeting. Notice of any telephonic meetings of the

<PAGE>   45
                                      -38-



Notices shall contain a brief statement of the time, place and anticipated
purposes of the meeting. The presence (whether in person or by telephone) of a
Regular Trustee at a meeting shall constitute a waiver of notice of such meeting
except where a Regular Trustee attends a meeting for the express purpose of
objecting to the transaction of an activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this
Declaration, any action of the Regular Trustees may be taken at a meeting by
vote of a majority of the Regular Trustees present (whether in person or by
telephone) and eligible to vote with respect to such matter, provided that a
Quorum is present, or without a meeting by the unanimous written consent of the
Regular Trustees. In the event there is only one Regular Trustee, any and all
action of such Regular Trustee shall be evidenced by a written consent of such
Regular Trustee.

                  The definitive Certificates shall be printed, lithographed or
engraved or produced by any combination of these methods on steel engraved
borders or may be produced in any other manner permitted by the rules of any
securities exchange on which the Securities may be listed, all as determined by
the Regular Trustees, as evidenced by their execution thereof. The Trust shall
issue no Securities in bearer form.

SECTION 7.4  Form of Preferred Securities Certificates; Global Certificates.

                  (a) Unless otherwise specified in the terms of the Preferred
Securities, the Preferred Securities Certificates, on original issuance, will be
issued in the form of one or more, fully registered, global Preferred Security
Certificates (each a "Global Certificate"), to be delivered to The Depository
Trust Company, the initial Clearing Agency, by, or on behalf of, the Trust. No
Preferred Security Beneficial Owner will receive a definitive Preferred Security
Certificate representing such Preferred Security Beneficial Owner's interests in
such Global Certificates, except as provided in Section 7.7

                  (b) Unless required by the Depositary, any securities exchange
on which the Preferred Securities may be listed or quoted for trading or any
rule, regulation or law, Preferred Securities issued in the form of Global

         IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS
         MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
         AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE
         HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH
         AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

SECTION 7.5 Execution and Dating of Certificates.

                  The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. In case any Regular Trustee who shall have signed any of the
Certificates shall cease to be such Regular Trustee before the Certificates so
signed shall be delivered by the Trust, such Certificates nevertheless may be
delivered as though the person who signed such Certificates had not ceased to be
such Regular Trustee; and any Certificates may be signed on behalf of the Trust
by such persons who, at the actual date of execution of such Certificate, shall
be the Regular Trustees of the Trust, although at the date of the execution and
delivery of the Declaration any such person was not such a Regular Trustee. Each
Preferred Security shall be dated the date of its authentication.

                  One Regular Trustee shall sign the Preferred Security
Certificates for the Trust by manual or facsimile signature. Unless otherwise
determined by the Trust, such signature shall, in the case of Common Security
Certificates, be a manual signature.

SECTION 7.6  Authentication of Preferred Security Certificates.

                  Each Global Certificate shall initially be registered on the
books and records of he Trust in the name of Cede & Co., the nominee of The
Depositary Trust Company, and delivered to such Depositary or a nominee thereof
or custodian therefor, and each such Global Certificate shall constitute a
single Preferred Security for all purposes of this Declaration.

                  A Preferred Security Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the
Institutional Trustee. The signature shall be conclusive evidence that the
Preferred Security Certificate has been authenticated under this Declaration.
Upon a written 


<PAGE>   49
                                      -42-



order of the Trust signed by one Regular Trustee, the Institutional Trustee
shall authenticate the Preferred Security Certificates for original issue.

                  The Institutional Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Preferred Security Certificates. An
authenticating agent may authenticate Preferred Security Certificates whenever
the Institutional Trustee may do so. Each reference in this Declaration to
authentication by the Institutional Trustee includes authentication by such
agent. An authenticating agent has the same rights as the Institutional Trustee
to deal with the Sponsor or an Affiliate.

SECTION 7.7  Definitive Preferred Security Certificates.

                  (a) Upon the occurrence of an event specified in Section
8.2(a), definitive, fully registered Preferred Security Certificates
("Definitive Preferred Security Certificates") shall be prepared by the Regular
Trustees on behalf of the Trust with respect to such Preferred Securities.

                  (b) Upon surrender of the Global Certificates by the Clearing
Agency, accompanied by registration instructions, the Regular Trustees shall
cause Definitive Preferred Security Certificates to be delivered to Preferred
Security Beneficial Owners in accordance with the instructions of the Clearing
Agency. Neither the Trustees nor the Trust shall be liable for any delay in
delivery of such instructions and each of them may conclusively rely on and
shall be protected in relying on, said instructions of the Clearing Agency.

SECTION 7.8 Temporary Certificates.

                  Until definitive Certificates are ready for delivery, the
Trust may prepare and, in the case of the Preferred Securities, the
Institutional Trustee shall authenticate temporary Certificates. Temporary
Certificates shall be substantially in the form of definitive Certificates but
may have variations that the Trust considers appropriate for temporary
Certificates. Without unreasonable delay, the Trust shall prepare and, in the
case of the Preferred Securities, the Institutional Trustee shall authenticate
definitive Certificates in exchange for temporary Certificates.

SECTION 7.9  Registrar, Paying Agent and Conversion Agent.

                  In the event that the Preferred Securities are not in book
entry only form, the Trust shall maintain in the Borough of Manhattan, City of
New York, State of New York, an office or agency where Preferred Securities may
be presented for registration of transfer or from exchange ("Registrar"), (ii)
an office or agency where Preferred Securities may be presented for payment
("Paying Agent"). The Trust shall maintain an office or agency where Securities
may be presented for conversion ("Conversion Agent"). The Registrar shall keep a
register of the Preferred Securities and of their transfer and exchange. The
Trust may appoint the Registrar, the Paying Agent and the Conversion Agent and
may appoint one or more coregistrars, one or more additional paying agents and
one or more additional conversion agents in such other locations as it shall
determine. The term "Paying Agent" includes any additional paying agent and the
term "Conversion Agent" includes any additional conversion agent. The Trust may
change any Paying Agent, Registrar, co-registrar or Conversion Agent without
prior notice to any Holder. The Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Regular Trustees. The Trust
shall notify the Institutional Trustee of the name and address of any Agent not
a party to this Declaration. If the Trust fails to appoint or maintain another
entity as Registrar, Paying Agent or Conversion Agent, the Institutional Trustee
shall act as such. The Trust or any of its Affiliates may act as Paying Agent,
Registrar, or Conversion Agent.

                  The Trust initially appoints the Institutional Trustee as
Registrar, Paying Agent and Conversion Agent for the Preferred Securities. The
Institutional Trustee shall be entitled to the protections of Sections 5.12 and
5.13 and Article IX in its capacity as Registrar, Paying Agent and Conversion
Agent.

SECTION 7.10  Paying Agent to Hold Money in Trust.

                  The Trust shall require each Paying Agent other than the
Institutional Trustee to agree in writing that the Paying Agent will hold in
trust for the benefit of Holders or the Institutional Trustee all money held by
the Paying Agent for the payment of principal or distribution on the Securities,
and will notify the Institutional Trustee if there are insufficient funds. While
any such insufficiency continues, the Institutional Trustee may require a Paying
Agent to pay all money held by it to the Institutional Trustee. The Trust at any
time may 


<PAGE>   51
                                      -44-



require a Paying Agent to pay all money held by it to the Institutional Trustee
and to account for any money disbursed by it. Upon payment over to the
Institutional Trustee, the Paying Agent (if other than the Trust or an Affiliate
of the Trust) shall have no further liability for the money. If the Trust or the
Sponsor or an Affiliate of the Trust or the Sponsor acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent.

SECTION 7.11  Outstanding Preferred Securities.

                  The Preferred Securities outstanding at any time are all the
Preferred Securities authenticated by the Institutional Trustee except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section 7.11 as not outstanding.

                  If a Preferred Security is replaced or paid pursuant to
Section 8.3, it ceases to be outstanding unless the Institutional Trustee
receives proof satisfactory to it that the replaced, paid or purchased Preferred
Security is held by a bona fide purchaser.

                  If Preferred Securities are considered paid in accordance with
the terms of this Declaration, they cease to be outstanding and interest on them
ceases to accrue.

                  A Preferred Security does not cease to be outstanding because
one of the Trust, the Sponsor or an Affiliate of the Sponsor holds the Preferred
Security.

SECTION 7.12 Preferred Securities in Treasury.

                  In determining whether the Holders of the required amount of
Securities have concurred in any direction, waiver or consent, Preferred
Securities owned by the Trust, the Sponsor or an Affiliate of the Sponsor, as
the case may be, shall be disregarded and deemed not to be outstanding, except
that for the purposes of determining whether the Institutional Trustee shall be
fully protected in relying on any such direction, waiver or consent, only
Preferred Securities which the Institutional Trustee knows are so owned shall be
so disregarded.

SECTION 7.13 Notices to Clearing Agency.

                  Whenever a notice or other communication to the Preferred
Security Holders is required under this Declaration, the Regular Trustees shall,
in the case of any Global Preferred Security, give all such notices and
communications specified herein to be given to the Preferred Security Holders to
the Depositary, and shall have no notice obligations to the Preferred Security
Beneficial Owners.

SECTION 7.14  Appointment of Successor Clearing Agency.

                  If the Depositary elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency with
respect to such Preferred Securities.

SECTION 7.15  Deemed Security Holders.

                  The Trustees and any Agent may treat the Person in whose name
any Certificate shall be registered on the books and records of the Trust as the
sole holder of such Certificate and of the Securities represented by such
Certificate for purposes of receiving Distributions and for all other purposes
whatsoever and, accordingly, shall not be bound to recognize any equitable or
other claim to or interest in such Certificate or in the Securities represented
by such Certificate on the part of any Person, whether or not the Trust shall
have actual or other notice thereof.

                                  ARTICLE VIII

                     TRANSFERS, EXCHANGES AND CANCELLATIONS
                                  OF SECURITIES

SECTION 8.1  General.

                  (a) Where Preferred Security Certificates are presented to the
Registrar or a co-registrar with a request to register a transfer or to exchange
them for an equal number of Preferred Securities represented by different
certificates, the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met. To permit registrations of
transfers and exchanges, the Trust shall issue and the Institutional Trustee
shall authenticate Preferred Security Certificates at the Registrar's request.

                  (b) Securities may only be transferred, in whole or in part,
in accordance with the terms and conditions set forth in this Declaration and in
the Terms set forth in Annex I. Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

                  (c) Subject to this Article VIII, the Sponsor and any Related
Party may only transfer Common Securities to the Sponsor or a Related Party of
the Sponsor; provided that, any such transfer is subject to the condition
precedent that the transferor obtain the written opinion of nationally
recognized independent counsel experienced in such matters that such transfer
would not cause more than an insubstantial risk that:

                    (i)    the Trust would not be classified for United
         States federal income tax purposes as a grantor trust; and

                   (ii) the Trust would be an Investment Company or the
         transferee would become an Investment Company.

                  (d) The Regular Trustees shall provide for the registration of
Securities and of transfers of Securities, which will be effected without charge
but only upon payment (with such indemnity as the Regular Trustees may require)
in respect of any tax or other governmental charges that may be imposed in
relation to it. Upon surrender for registration of transfer of any Certificates,
the Regular Trustees shall cause one or more new Certificates to be issued in
the name of the designated transferee or transferees. Every Certificate
surrendered for registration of transfer shall be accompanied by a written
instrument of transfer in form satisfactory to the Regular Trustees duly
executed by the Holder or such Holder's attorney duly authorized in writing.
Each Certificate surrendered for registration of transfer shall be canceled by
the Regular Trustees. A transferee of a Certificate shall be entitled to the
rights and subject to the obligations of a Holder hereunder upon the receipt by
such transferee of a Certificate. By acceptance of a Certificate, each
transferee shall be deemed to have agreed to be bound by this Declaration.

                  (e) The Trust shall not be required (i) to issue, register the
transfer of or exchange Preferred Security Certificates during a period
beginning at the opening of business 15 days before the day of any selection of
Preferred Securities for redemption and ending at 5:00 p.m. (New York City time)
on the day of selection, or (ii) to register the transfer or exchange of any
Preferred Security so selected for redemption 


<PAGE>   54
                                      -47-



in whole or in part, except the unredeemed portion of any Preferred Security
being redeemed in part.

SECTION 8.2  Transfer Procedures and Restrictions for Global Certificates.

                  (a) Notwithstanding any other provision in this Declaration,
no Global Certificate may be exchanged in whole or in part for Preferred
Securities registered, and no transfer of a Global Certificate in whole or in
part may be registered, in the name of any Person other than the Depositary for
such Global Certificate or a nominee thereof or a successor Depositary or a
nominee of such successor Depositary, unless (i) such Depositary (x) has
notified the Sponsor that it is unwilling or unable to continue as Depositary
for such Global Certificate and is not replaced by a successor Depositary
approved by the Sponsor within 90 days or (y) at any time has ceased to be a
clearing agency registered under the Exchange Act, or (ii) an Event of Default
has occurred and is continuing.

                  (b) The transfer and exchange of Global Certificates or
beneficial interests therein shall be effected through the Clearing Agency, in
accordance with this Declaration and the procedures of the Clearing Agency
therefor.

                  (c) Unless and until Definitive Preferred Security
Certificates have been issued to the Preferred Security
Beneficial owners pursuant to Section 7.7:

                    (i) the Trust and the Trustees shall be entitled to deal
         with the Clearing Agency for all purposes of this Declaration
         (including the payment of Distributions on the Global Certificates and
         receiving approvals, votes or consents hereunder) as the Holder of the
         Preferred Securities and the sole holder of the Global Certificates and
         shall have no obligation to the Preferred Security Beneficial owners;
         and

                   (ii) the rights of the Preferred Security Beneficial Owners
         shall be exercised only through the Clearing Agency and shall be
         limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or the
         Clearing Agency Participants and receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants. The Depositary will make book entry transfers among the
         Clearing Agency Participants.

SECTION 8.3  Mutilated, Destroyed, Lost or Stolen Certificates; Replacement
             Securities.

                  If the holder of a Security claims that the Certificate
representing such Security has been lost, destroyed or wrongfully taken or if
such Certificate is mutilated and is surrendered to the Trust or in the case of
the Preferred Securities to the Institutional Trustee, the Trust shall issue and
the Institutional Trustee shall authenticate a replacement Certificate if the
Institutional Trustee's and the Trust's requirements, as the case may be, are
met. If required by the Institutional Trustee or the Trust, an indemnity bond
must be sufficient in the judgment of both to protect the Trustees, the
Institutional Trustee, the Sponsor or any authenticating agent from any loss
which any of them may suffer if a Certificate is replaced. The Company may
charge for its expenses in replacing a Certificate.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Sponsor in its discretion
may, instead of issuing a new Certificate, pay such Security.

                  Every replacement Certificate is an additional obligation of
the Trust.

SECTION 8.4  Cancellation of Preferred Security Certificates.

                  The Trust at any time may deliver Preferred Security
Certificates to the Institutional Trustee for cancellation. The Registrar,
Paying Agent and Conversion Agent shall forward to the Institutional Trustee any
Preferred Securities surrendered to them for registration of transfer,
redemption, conversion, exchange or payment. The Institutional Trustee shall
promptly cancel all Preferred Securities surrendered for registration of
transfer, redemption, conversion, exchange, payment, replacement or cancellation
and shall dispose of cancelled Preferred Securities as the Trust directs. The
Trust may not issue new Preferred Securities to replace Preferred Securities
that it has paid or that have been delivered to the Institutional Trustee for
cancellation or that any holder has converted.

                           LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES AND OTHERS

SECTION 9.1  Liability.

                  (a)      Except as expressly set forth in this Declaration,
the Securities Guarantees and the terms of the Securities, the
Sponsor shall not be:

                    (i) personally liable for the return of any portion of the
         capital contributions (or any return thereon) of the Holders of the
         Securities which shall be made solely from assets of the Trust; or

                   (ii) required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution of the Trust or otherwise.

                  (b)      The Holder of the Common Securities shall be liable
for all of the debts and obligations of the Trust (other than with respect to
the Securities) to the extent not satisfied out of the Trust's assets.

                  (c)      Pursuant to Section 3803(a) of the Business Trust
Act, the Holders of the Preferred Securities shall be entitled to the same
limitation of personal liability as is extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

SECTION 9.2  Exculpation.

                  (a)      No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or, in
the case of the Institutional Trustee, negligence) or willful misconduct with
respect to such acts or omissions.

                  (b)      An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon 



<PAGE>   57
                                      -50-


such information, opinions, reports or statements presented to the Trust by any
Person as to matters the Indemnified Person reasonably believes are within such
other Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be paid.

SECTION 9.3 Fiduciary Duty.

                  (a)      To the extent that, at law or in equity, an 
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Declaration shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration. The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than the duties imposed on the Institutional Trustee
under the Trust Indenture Act), are agreed by the parties hereto to replace such
other duties and liabilities of such Indemnified Person.

                  (b)      Unless otherwise expressly provided herein:

                    (i)    whenever a conflict of interest exists or arises
         between an Indemnified Person and any Covered Person or

                   (ii) whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or 



<PAGE>   58
                                      -51-

obligation of the Indemnified Person at law or in equity or otherwise.

                  (c)      Whenever in this Declaration an Indemnified Person
is permitted or required to make a decision:

                    (i) in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                   (ii) in its "good faith" or under another express standard,
         the Indemnified Person shall act under such express standard and shall
         not be subject to any other or different standard imposed by this
         Declaration or by applicable law.

SECTION 9.4  Indemnification.

                  (a)      (i)      The Debenture Issuer shall indemnify, to the
         full extent permitted by law, any Company Indemnified Person
         who was or is a party or is threatened to be made a party to
         any threatened, pending or completed action, suit or proceeding,
         whether civil, criminal, administrative or investigative (other than an
         action by or in the right of the Trust) by reason of the fact that he
         is or was a Company Indemnified Person against expenses (including
         attorneys' fees), judgments, fines and amounts paid in settlement
         actually and reasonably incurred by him in connection with such action,
         suit or proceeding if he acted in good faith and in a manner he
         reasonably believed to be in or not opposed to the best interests of
         the Trust, and, with respect to any criminal action or proceeding, had
         no reasonable cause to believe his conduct was unlawful. The
         termination of any action, suit or proceeding by judgment, order,
         settlement, conviction, or upon a plea of nolo contendere or its
         equivalent, shall not, of itself, create a presumption that the Company
         Indemnified Person did not act in good faith and in a manner which he
         reasonably believed to be in or not opposed to the best interests of
         the Trust, and, with respect to any criminal action or proceeding, had
         reasonable cause to believe that his conduct was unlawful.

                                      -52-


                  (ii) The Debenture Issuer shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection with the defense
         or settlement of such action or suit if he acted in good faith and in a
         manner he reasonably believed to be in or not opposed to the best
         interests of the Trust and except that no such indemnification shall be
         made in respect of any claim, issue or matter as to which such Company
         Indemnified Person shall have been adjudged to be liable to the Trust
         unless and only to the extent that the Court of Chancery of Delaware or
         the court in which such action or suit was brought shall determine upon
         application that, despite the adjudication of liability but in view of
         all the circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such expenses which such Court of Chancery or
         such other court shall deem proper.

                  (iii) To the extent that a Company Indemnified Person shall be
         successful on the merits or otherwise (including dismissal of an action
         without prejudice or the settlement of an action without admission of
         liability) in defense of any action, suit or proceeding referred to in
         paragraphs (i) and (ii) of this Section 9.4(a), or in defense of any
         claim, issue or matter therein, he shall be indemnified, to the full
         extent permitted by law, against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection therewith.

                  (iv) Any indemnification under paragraphs (i) and (ii) of this
         Section 9.4(a) (unless ordered by a court) shall be made by the
         Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person is
         proper in the circumstances because he has met the applicable standard
         of conduct set forth in paragraphs (i) and (ii). Such determination
         shall be made (1) by the Regular Trustees by a majority vote of a
         quorum consisting of such Regular Trustees who were not parties to such
         action, suit or proceeding, (2) if such a quorum is not obtainable, or,
         even if obtainable, if a quorum of disinterested Regular Trustees so
         directs, by independent legal counsel in a written

<PAGE>   60
                                      -53-


         opinion, or (3) by the Holders of the Common Securities of the Trust.

                  (v) Expenses (including attorneys, fees) incurred by a Company
         Indemnified Person in defending a civil, criminal, administrative or
         investigative action, suit or proceeding referred to in paragraphs (i)
         and (ii) of this Section 9.4(a) shall be paid by the Debenture Issuer
         in advance of the final disposition of such action, suit or proceeding
         upon receipt of an undertaking by or on behalf of such Company
         Indemnified Person to repay such amount if it shall ultimately be
         determined that he is not entitled to be indemnified by the Debenture
         Issuer as authorized in this Section 9.4(a). Notwithstanding the
         foregoing, no advance shall be made by the Debenture Issuer if a
         determination is reasonably and promptly made (i) by the Regular
         Trustees by a majority vote of a quorum of disinterested Regular
         Trustees, (ii) if such a quorum is not obtainable, or, even if
         obtainable, if a quorum of disinterested Regular Trustees so directs,
         by independent legal counsel in a written opinion or (iii) the Holders
         of the Common Securities of the Trust, that, based upon the facts known
         to the Regular Trustees, counsel or the Holders of the Common
         Securities at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful. In no event shall any advance be made in
         instances where the Regular Trustees, independent legal counsel or the
         Holders of the Common Securities reasonably determine that such person
         deliberately breached his duty to the Trust or the Holders of the
         Common or Preferred Securities.

                  (vi) The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section 9.4(a)
         shall not be deemed exclusive of any other rights to which those
         seeking indemnification and advancement of expenses may be entitled
         under any agreement, vote of stockholders or disinterested directors of
         the Debenture Issuer or Holders of the Preferred Securities of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office. All rights to
         indemnification under this Section 9.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each 



<PAGE>   61
                                      -54-


         Company Indemnified Person who serves in such capacity at any time
         while this Section 9.4(a) is in effect. Any repeal or modification of
         this Section 9.4(a) shall not affect any rights or obligations then
         existing.

                  (vii) The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 9.4(a).

                  (viii) For purposes of this Section 9.4(a), references to "the
         Trust" shall include, in addition to the resulting or surviving entity,
         any constituent entity (including any constituent of a constituent)
         absorbed in a consolidation or merger, so that any person who is or was
         a director, trustee, officer or employee of such constituent entity, or
         is or was serving at the request of such constituent entity as a
         director, trustee, officer, employee or agent of another entity, shall
         stand in the same position under the provisions of this Section 9.4(a)
         with respect to the resulting or surviving entity as he would have with
         respect to such constituent entity if its separate existence had
         continued.

                  (ix) The indemnification and advancement of expenses provided
         by, or granted pursuant to, this Section 9.4(a) shall, unless otherwise
         provided when authorized or ratified, continue as to a person who has
         ceased to be a Company Indemnified Person and shall inure to the
         benefit of the heirs, executors and administrators of such a person.

                  (b) The Sponsor agrees to indemnify the (i) Institutional
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Institutional
Trustee and the Delaware Trustee, and (iv) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Institutional Trustee and the Delaware Trustee (each
of the Persons in (i) through (iv) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any and all loss, liability or expense including taxes (other than taxes based
on the income of such Fiduciary Indemnified Person) incurred without negligence
or bad faith on its part, arising out of or in connection with the acceptance or
administration or the trust or trusts 


<PAGE>   62
                                      -55-


hereunder, including the costs and expenses (including reasonable legal fees and
expenses) of defending itself against or investigating any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder. The obligation to indemnify as set forth in this Section 9.4(b) shall
survive the satisfaction and discharge of this Declaration.

SECTION 9.5 Outside Businesses.

                  Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional Trustee may engage in or possess an interest in other business
ventures of any nature or description, independently or with others, similar or
dissimilar to the business of the Trust, and the Trust and the Holders of
Securities shall have no rights by virtue of this Declaration in and to such
independent ventures or the income or profits derived therefrom, and the pursuit
of any such venture, even if competitive with the business of the Trust, shall
not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware
Trustee, or the Institutional Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust, could be taken by the Trust,
and any Covered Person, the Sponsor, the Delaware Trustee and the Institutional
Trustee shall have the right to take for its own account (individually or as a
partner or fiduciary) or to recommend to others any such particular investment
or other opportunity. Any Covered Person, the Delaware Trustee and the
Institutional Trustee may engage or be interested in any financial or other
transaction with the Sponsor or any Affiliate of the Sponsor, or may act as
depositary for, trustee or agent for, or act on any committee or body of holders
of, securities or other obligations of the Sponsor or its Affiliates.

SECTION 10.2  Certain Accounting Matters.

                  (a) At all times during the existence of the Trust, the
Regular Trustees shall keep, or cause to be kept, full books of account, records
and supporting documents, which shall reflect in reasonable detail, each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year by a firm of independent certified public accountants
selected by the Regular Trustees.

                  (b) The Regular Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                  (c) The Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, any annual United States federal
income tax information statement required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations. Notwithstanding any right under the Code
to deliver any such statement at a later date, the Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

                  (d) The Regular Trustees shall cause to be duly prepared and
filed with the appropriate taxing authority, an annual United States federal
income tax return, on a Form 1041 or such other form required by the Code, and
any other annual income tax returns required to be filed by the Regular Trustees
on behalf of the Trust with any state or local taxing authority.

SECTION 10.3  Banking.

                  The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Institutional Trustee shall be
made directly to the Institutional Trustee Account and no other funds of the
Trust 



<PAGE>   64
                                      -57-


shall be deposited in the Institutional Trustee Account. The sole signatories
for such accounts shall be designated by the Regular Trustees; provided,
however, that the Institutional Trustee shall designate the signatories for the
Institutional Trustee Account.

SECTION 10.4  Withholding.

                  The Trust and the Regular Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Regular Trustee shall file required
forms with applicable jurisdictions and, unless an exemption from withholding is
properly established by a Holder, shall remit amounts withheld with respect to
the Holder to applicable jurisdictions. To the extent that the Trust is required
to withhold and pay over any amounts to any authority with respect to
distributions or allocations to any Holder, the amount withheld shall be deemed
to be a distribution in the amount of the withholding to the Holder. In the
event of any claimed overwithholding, Holders shall be limited to an action
against the applicable jurisdiction. If the amount required to be withheld was
not withheld from actual Distributions made, the Trust may reduce subsequent
Distributions by the amount of such withholding.

                  powers of the Institutional Trustee in contravention of
                  the Trust Indenture Act; or

                           (C)      cause the Trust to be deemed to be an
                  Investment Company that is required to be registered

effected only with such additional requirements as may be set forth in the terms
of such Securities.

                  (d) Section 8.1(c) and this Section 11.1 shall not be amended
without the consent of all of the Holders of the Securities.

                  (e) Article IV and the rights of the holders of the Common

         not have a material adverse effect on the rights, preferences or
         privileges of the Holders.



SECTION 11.2 Meetings of the Holders of Securities; 
             Action by Written Consent.

                  (a) Meetings of the Holders of any class of Securities may be
called at any time by the Regular Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Preferred
Securities are listed or quoted for trading. The Regular Trustees shall call a
meeting of the Holders of such class if directed to do so by the Holders of at
least 10% in liquidation amount of such class of Securities. Such direction
shall be given by delivering to the Regular Trustees one or more calls in a
writing stating that the signing Holders 
<PAGE>   67
                                      -60-


of Securities wish to call a meeting and indicating the general or specific
purpose for which the meeting is to be called. Any Holders of Securities calling
a meeting shall specify in writing the Certificates held by the Holders of
Securities exercising the right to call a meeting and only those Securities
represented by the Certificates so specified shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

                  (b)      Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to
meetings of Holders of Securities:

                    (i) notice of any such meeting shall be given to all the
         Holders of Securities having a right to vote thereat at least seven
         days and not more than 60 days before the date of such meeting.
         Whenever a vote, consent or approval of the Holders of Securities is
         permitted or required under this Declaration or the rules of any stock
         exchange or over-the-counter market on which the Preferred Securities
         are listed or quoted for trading, such vote, consent or approval may be
         given at a meeting of the Holders of Securities. Any action that may be
         taken at a meeting of the Holders of Securities may be taken without a
         meeting if a consent in writing setting forth the action so taken is
         signed by the Holders of Securities owning not less than the minimum
         amount of Securities in liquidation amount that would be necessary to
         authorize or take such action at a meeting at which all Holders of
         Securities having a right to vote thereon were present and voting.
         Prompt notice of the taking of action without a meeting shall be given
         to the Holders of Securities entitled to vote who have not consented in
         writing. The Regular Trustees may specify that any written ballot
         submitted to the Security Holders for the purpose of taking any action
         without a meeting shall be returned to the Trust within the time
         specified by the Regular Trustees;

                   (ii) each Holder of a Security may authorize any Person to
         act for it by proxy on all matters in which a Holder of Securities is
         entitled to participate, including waiving notice of any meeting, or
         voting or participating at a meeting. No proxy shall be valid after the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy. Every proxy shall be revocable at the pleasure of the
         Holder of Securities executing it. Except as otherwise provided herein,

                  a rate per annum of [   ]% (the "Coupon Rate") of the
                  stated liquidation amount of $25 per Security, such
                  rate being the rate of interest payable on the
                  Debentures to be held by the Institutional Trustee.
                  Distributions in arrears for more than one quarter will
                  bear interest thereon compounded quarterly at the
                  Coupon Rate (to the extent permitted by applicable
                  law).  The term "Distributions" as used herein includes
                  any such interest including any Additional Interest and
                  Compounded Interest payable unless otherwise stated. A
                  Distribution is payable only to the extent that
                  payments are made in respect of the Debentures held by
                  the Institutional Trustee and to the extent the Trust
                  has funds available therefor.  The amount of
                  Distributions payable for any period will be computed
                  for any full quarterly Distribution period on the basis
                  of a 360-day year of twelve 30-day months, and for any
                  period shorter than a full quarterly Distribution
                  period for which Distributions are computed,
                  Distributions will be computed on the basis of the
                  actual number of days elapsed per 90-day quarter.

         (b)      Except as otherwise described below, Distributions on
                  the Securities will be cumulative, will accrue from the
                  date of initial issuance and will be payable quarterly
                  in arrears, on the following dates, which



                                      I-2
<PAGE>   76

                  dates correspond to the interest payment dates on the
                  Debentures: March 31, June 30, September 30 and December 31 of
                  each year, commencing on March 31, 1997, when, as and if
                  available for payment by the Institutional Trustee. The
                  Debenture Issuer has the right at any time during the term of
                  the Debentures to defer interest payments from time to time by
                  extending the interest payment period for successive periods
                  not exceeding 20 consecutive quarters (each, an "Extension
                  Period") for each such period; provided that no Extension
                  Period may extend beyond the maturity date of the Debentures.
                  As a consequence of such extension, quarterly Distributions on
                  the Securities would be deferred (though such Distributions
                  would continue to accrue with interest since interest would
                  continue to accrue on the Debentures) during any such extended
                  interest payment period. In the event that the Debenture
                  Issuer exercises this right, then, during such period, (a) the
                  Debenture Issuer 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 Debenture
                  Issuer of its obligations under any employee benefit plans or
                  the satisfaction by the Debenture Issuer of its obligations
                  pursuant to any contract or security requiring the Debenture
                  Issuer to purchase shares of the Common Stock, (ii) as a
                  result of a reclassification of the Debenture Issuer's capital
                  stock or the exchange or conversion of one class or series of
                  the Debenture Issuer's capital stock for another class or
                  series of the Debenture Issuer's capital stock, (iii) the
                  purchase of fractional interests in shares of the Debenture
                  Issuer'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
                  Debenture Issuer where the dividend stock is the same stock as
                  that on which the dividend is paid), (b) the Debenture Issuer
                  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 Debenture
                  Issuer which rank pari passu with or junior to the Debentures
                  and (c) the Debenture Issuer 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 Debenture Issuer may further extend the





                                      I-3
<PAGE>   77

                  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 Debentures. Upon the
                  termination of any Extension Period and the payment of all
                  amounts then due, the Debenture Issuer may commence a new
                  Extension Period, subject to the above requirements.

         (c)      Distributions on the Securities will be payable to the
                  Holders thereof as they appear on the books and records
                  of the Trust on the relevant record dates.  The
                  relevant record dates shall be the March 15, June 15,
                  September 15 and December 15 prior to the next
                  succeeding payment dates, except as otherwise described
                  in this Annex I to the Declaration.  Subject to any
                  applicable laws and regulations and the provisions of
                  the Declaration, each such payment in respect of the
                  Preferred Securities being held in book-entry form
                  through The Depository Trust Company (the "Depositary")
                  will be made as described under the heading
                  "Description of the Preferred Securities -- Book Entry
                  Only Issuance -- The Depository Trust Company" in the
                  Registration Statement.  The relevant record dates for
                  the Common Securities shall be the same record dates as
                  for the Preferred Securities.  Distributions payable on
                  any Securities that are not punctually paid on any
                  Distribution payment date as a result of the Debenture
                  Issuer having failed to make a payment under the
                  Debentures, will cease to be payable to the Person in
                  whose name such Securities are registered on the
                  relevant record date, and such defaulted Distribution
                  will instead be payable to the Person in whose name
                  such Securities are registered on the special record
                  date or other specified date determined in accordance
                  with the Indenture.  If any date on which Distributions
                  are payable on the Securities is not a Business Day,
                  then payment of the Distribution payable on such date
                  will be made on the next succeeding day that is a
                  Business Day (and without any distribution or other
                  payment in respect of any such delay) except that, if
                  such Business Day is in the next succeeding calendar
                  year, 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.

         (d)      In the event of an election by the Holder to convert
                  its Securities through the Conversion Agent into
                  Common Stock of the Debenture Issuer pursuant to the



                                      I-4
<PAGE>   78

                  terms of the Securities as set forth in this Annex I to the
                  Declaration, accrued Distributions will not be paid on
                  Preferred Securities that are converted, nor will any payment,
                  allowance or adjustment be made for accumulated and unpaid
                  Distributions, whether or not in arrears, on converted
                  Preferred Securities except that if any Preferred Security is
                  converted (i) on or after a record date for payment of
                  Distributions thereon, the amount of the Distributions payable
                  on the related payment date with respect to such Preferred
                  Security shall be paid by the converting Holder to the Trust
                  and the Distributions payable on the related payment date with
                  respect to such Preferred Security shall be distributed to the
                  Holder as of such record date, despite such conversion, and
                  (ii) during an Extension Period and after the Institutional
                  Trustee mails a notice of redemption of the Preferred
                  Securities that are converted, accrued and unpaid
                  Distributions through the date of conversion on such Preferred
                  Securities called for redemption shall be distributed to the
                  Holder who converts such Preferred Securities, which
                  Distribution shall be made on the redemption date.

         (e)      In the event that there is any money or other property held by
                  or for the Trust that is not accounted for hereunder, such
                  property shall be distributed Pro Rata (as defined in
                  paragraph 9) among the Holders of the Securities.

3.       Liquidation Distribution Upon Dissolution.

                  In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust (each a "Liquidation"), the then Holders
of the Securities on the date of the Liquidation will be entitled to receive out
of the assets of the Trust available for distribution to Holders of Securities
after satisfaction of liabilities of creditors, Distributions in an amount equal
to the aggregate of the stated liquidation amount of $25 per Security plus
accrued and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
Liquidation, Debentures in an aggregate principal amount equal to the aggregate
stated liquidation amount of such Securities, with an interest rate equal to the
Coupon Rate of, and bearing accrued and unpaid interest in an amount equal to
the accrued and unpaid Distributions on, such Securities, shall be distributed
on a Pro Rata basis to the Holders of the Securities.



                                      I-5
<PAGE>   79

                  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 Securities shall be paid on a Pro Rata basis in
accordance with paragraph 9 below.

4.       Redemption and Distribution.

         (a)      Upon the repayment of the Debentures, in whole or in part,
                  whether at maturity or upon redemption (either at the option
                  of the Debenture Issuer or pursuant to a Tax Event), the
                  proceeds from such repayment or payment shall be
                  simultaneously applied to redeem Securities having an
                  aggregate liquidation amount equal to the aggregate principal
                  amount of the Debentures so repaid or redeemed at a redemption
                  price equal to the redemption price of such repaid or redeemed
                  Debentures, together with accrued and unpaid Distributions
                  thereon through the date fixed for redemption, payable in cash
                  (the "Redemption Price").

         (b)      If fewer than all the outstanding Securities are to be so
                  redeemed, the Common Securities and the Preferred Securities
                  will be redeemed Pro Rata and the Preferred Securities to be
                  redeemed will be as described in paragraph 4(f)(ii) below.

         (c)      If, at any time, a Tax Event or an Investment Company
                  Event (each as defined below and each a "Special
                  Event") shall occur and be continuing, the Regular
                  Trustees shall, unless the Debentures are redeemed in
                  the limited circumstances in relation to a Tax Event
                  described in the following paragraph of this paragraph
                  4(c), dissolve the Trust and, after satisfaction of
                  creditors of the Trust, if any, cause Debentures held
                  by the Institutional Trustee (w) having an aggregate
                  principal amount equal to the aggregate stated
                  liquidation amount of, (x) an interest rate identical
                  to the Coupon Rate of, (y) accrued and unpaid interest
                  on, and (z) the same record dates for payment as, the
                  Securities, to be distributed to the Holders of the
                  Securities in liquidation of such Holders' interest in
                  the Trust on a Pro Rata basis, within 90 days following
                  the occurrence of such Special Event (the "90 Day
                  Period"); provided, however, that in the case of a Tax
                  Event, such dissolution and distribution shall be
                  conditioned on the Regular Trustees' receipt of an
                  opinion of a nationally recognized independent tax
                  counsel experienced in such 



                                      I-6
<PAGE>   80

                  matters (a "No Recognition Opinion"), which opinion may rely
                  on 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 Debentures, and provided, further, that       
                  if at the time there is available to the Trust the
                  opportunity to eliminate, within the 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
                  Debenture Issuer has, or will cause, no adverse effect on the
                  Trust, the Debenture Issuer or the Holders of the Securities
                  ("Ministerial Action"), the Debenture Issuer or the Trust
                  will pursue such Ministerial Action in lieu of dissolution.

                                    If in the event of a Tax Event, (i) the
                  Debenture Issuer 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
                  Debenture Issuer would be precluded from deducting the
                  interest on the Debentures for United States federal income
                  tax purposes even if the Debentures were distributed to the
                  Holders of Securities in liquidation of such Holders' interest
                  in the Trust as described in this paragraph 4(c), or (ii) the
                  Regular Trustees shall have been informed by such a tax
                  counsel that it cannot deliver a No Recognition Opinion to the
                  Regular Trustees, the Debenture Issuer shall have the right,
                  upon not less than 30 nor more than 60 days' notice, to redeem
                  the Debentures, in whole or in part, for cash within 90 days
                  following the occurrence of such Tax Event, and promptly
                  following such redemption, Securities shall be redeemed at the
                  Redemption Price on a Pro Rata basis at $25 per security plus
                  accrued and unpaid distributions; provided, however, that if
                  at the time there is available to the Debenture Issuer or the
                  Trust the opportunity to eliminate, within such 90 Day Period,
                  the Tax Event by taking some Ministerial Action that has no
                  adverse effect on the Trust, the Holders of Securities or the
                  Debenture Issuer, the Trust or the Debenture Issuer will
                  pursue such Ministerial Action in lieu of redemption.

                                    "Tax Event" means that the Regular Trustees
                  shall have received an opinion of nationally 



                                      I-7
<PAGE>   81

                  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 
                  [            ], 1997), in either case after [             ],
                  1997, 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 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 Debenture Issuer to the Trust on
                  the Debentures would not be deductible, in whole or in part,
                  by the Debenture Issuer for United States federal income tax
                  purposes.

                                    "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 [               ], 1997.

                                    On the date fixed for any distribution of
                  Debentures, upon dissolution of the Trust: (i) the Securities
                  will no longer be deemed to be outstanding and (ii)
                  certificates representing Securities will be deemed to
                  represent beneficial interests in Debentures having an
                  aggregate principal amount equal to the stated liquidation
                  amount, and bearing accrued and unpaid interest equal to
                  accrued and unpaid Distributions, on such Securities until
                  such 


                                      I-8

                  certificates are presented to the Debenture Issuer or its
                  agent for transfer or reissuance.

         (d)      The Trust may not redeem fewer than all the outstanding
                  Securities unless all accrued and unpaid Distributions have
                  been paid on all Securities for all quarterly Distribution
                  periods terminating on or before the date fixed for
                  redemption.

         (e)      If the Debentures are distributed to the Holders of the
                  Securities, pursuant to the terms of the Indenture, the
                  Debenture Issuer will use its best efforts to have the
                  Debentures quoted for trading on the Nasdaq National Market
                  System or on such exchange as the Preferred Securities were
                  listed immediately prior to the distribution of the
                  Debentures.

         (f)      Redemption or Distribution Procedures.

                    (i)    Notice of any redemption of, or notice of
                           distribution of Debentures in exchange for, the
                           Securities (a "Redemption/Distribution Notice") will
                           be given by the Trust by mail to each Holder of
                           Securities to be redeemed or exchanged not fewer than
                           30 nor more than 60 days before the date fixed for
                           redemption or exchange thereof, which, in the case of
                           a redemption, will be the date fixed for redemption
                           of the Debentures.  For purposes of the calculation
                           of the date of redemption or exchange and the dates
                           on which notices are given pursuant to this paragraph
                           4(f)(i), a Redemption/Distribution Notice shall be
                           deemed to be given on the day such notice is first
                           mailed by first-class mail, postage prepaid, to
                           Holders of Securities.  Each Redemption/Distribution
                           Notice shall be addressed to the Holders of
                           Securities at the address of each such Holder
                           appearing in the books and records of the Trust.  No
                           defect in the Redemption/Distribution Notice or in
                           the mailing of either thereof with respect to any
                           Holder shall affect the validity of the redemption or
                           exchange proceedings with respect to any other
                           Holder.

                   (ii)    In the event that fewer than all the outstanding
                           Securities are to be redeemed, the Securities to
                           be redeemed shall be redeemed Pro Rata from each
                           Holder of Preferred Securities, it being
                           understood that, in respect of Preferred
                           Securities

                           registered in the name of and held of record by the
                           Depositary or its nominee (or any successor Clearing
                           Agency or its nominee), the distribution of the
                           proceeds of such redemption will be made to each
                           Clearing Agency Participant (or Person on whose
                           behalf such nominee holds such securities) in
                           accordance with the procedures applied by such agency
                           or nominee.

                  (iii)    If Securities are to be redeemed and the Trust gives
                           a Redemption/Distribution Notice (which notice is
                           irrevocable), then, provided that the Debenture
                           Issuer has paid the Institutional Trustee a
                           sufficient amount of cash in connection with the
                           related redemption or maturity of the Debentures, (A)
                           with respect to Preferred Securities held in
                           book-entry form, by 12:00 noon, New York City time,
                           on the redemption date, the Trust will deposit
                           irrevocably with the Depositary or its nominee (or
                           successor Clearing Agency or its nominee) funds
                           sufficient to pay the applicable Redemption Price
                           with respect to such Preferred Securities and will
                           give the Depositary irrevocable instructions and
                           authority to pay the applicable Redemption Price to
                           the Holders of such Preferred Securities represented
                           by the Global Certificates, and (B) with respect to
                           Preferred Securities issued in definitive form and
                           Common Securities, the Trust will irrevocably deposit
                           with the Paying Agent funds sufficient to pay the
                           amount payable on redemption to the Holders of such
                           Securities upon surrender of their certificates. If a
                           Redemption/Distribution Notice shall have been given
                           and funds deposited as required, then on the date of
                           such deposit, all rights of Holders of such
                           Securities so called for redemption will cease,
                           except the right of the Holders of such Securities to
                           receive the Redemption Price, but without interest
                           thereon. Neither the Regular Trustees nor the Trust
                           shall be required to register or cause to be
                           registered the transfer of any Securities that have
                           been so called for redemption. If any date fixed for
                           redemption of Securities is not a Business Day, then
                           payment of the amount 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, 




                                      I-10
<PAGE>   84

                           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 fixed for
                           redemption. If payment of the Redemption Price in
                           respect of any Securities is improperly withheld or
                           refused and not paid either by the Trust or by the
                           Debenture Issuer as guarantor pursuant to the
                           relevant Securities Guarantee, Distributions on such
                           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 amount payable upon
                           redemption (other than for purposes of calculating
                           any premium).

                  (iv)     In the event of any redemption in part, the Trust
                           shall not be required to (i) issue, register the
                           transfer of or exchange of any Preferred Security
                           during a period beginning at the opening of business
                           15 days before any selection for redemption of
                           Preferred Securities and ending at 5:00 p.m. (New
                           York City time) on the earliest date in which the
                           relevant notice of redemption is deemed to have been
                           given to all holders of Preferred Securities to be so
                           redeemed and (ii) register the transfer of or
                           exchange of any Preferred Securities so selected for
                           redemption, in whole or in part, except for the
                           unredeemed portion of any Preferred Securities being
                           redeemed in part.

                  (v)      Redemption/Distribution Notices shall be sent by the
                           Regular Trustees on behalf of the Trust to (A) in the
                           case of Preferred Securities held in book-entry form,
                           the Depositary and, in the case of Securities held in
                           definitive form, the Holders of such certificates and
                           (B) in respect of the Common Securities, the Holder
                           thereof.

                  (vi)     Subject to the foregoing and applicable law
                           (including, without limitation, United States federal
                           securities laws), the Debenture Issuer or any of 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.

5.       Conversion Rights.



                                      I-11
<PAGE>   85

         The Holders of Securities shall have the right at any time prior to
         5:00 p.m. (New York City time) on the Business Day immediately
         preceding the date of repayment of such Securities, whether at maturity
         or upon redemption (either at the option of the Debenture Issuer or
         pursuant to a Tax Event), at their option, to cause the Conversion
         Agent to convert Securities, on behalf of the converting Holders, into
         shares of Common Stock of the Debenture Issuer in the manner described
         herein on and subject to the following terms and conditions:

         (a)      The Securities will be convertible at the office of the
                  Conversion Agent into fully paid and nonassessable
                  shares of Common Stock of the Debenture Issuer pursuant
                  to the Holder's direction to the Conversion Agent to
                  exchange such Securities for a portion of the
                  Debentures theretofore held by the Trust on the basis
                  of one Security per $25 principal amount of Debentures,
                  and immediately convert such amount of Debentures into
                  fully paid and nonassessable shares of Common Stock of
                  the Debenture Issuer at an initial conversion rate of
                  [            ] shares of Common Stock of the Debenture
                  Issuer per $25 principal amount of Debentures (which is
                  equivalent to a conversion price of $[            ] per
                  share of Common Stock of the Debenture Issuer, subject
                  to certain adjustments set forth in the terms of the
                  Debentures (as so adjusted, "Conversion Price")).

         (b)      In order to convert Securities into Common Stock of the
                  Debenture Issuer, the Holder shall submit to the
                  Conversion Agent at the office referred to above an
                  irrevocable request to convert Securities on behalf of
                  such Holder (the "Conversion Request"), together, if
                  the Securities are in certificated form, with such
                  certificates.  The Conversion Request shall (i) set
                  forth the number of Securities to be converted and the
                  name or names, if other than the Holder, in which the
                  shares of Common Stock of the Debenture Issuer should
                  be issued and (ii) direct the Conversion Agent (A) to
                  exchange such Securities for a portion of the
                  Debentures held by the Trust (at the rate of exchange
                  specified in the preceding paragraph) and (B) to
                  immediately convert such Debentures on behalf of such
                  Holder, into Common Stock of the Debenture Issuer (at
                  the conversion rate specified in the preceding
                  paragraph).  The Conversion Agent shall notify the
                  Trust of the Holder's election to exchange Securities
                  for a portion of the Debentures held by the Trust and
                  the Trust shall, upon receipt of such notice, deliver to


                                      I-12
<PAGE>   86

                  the Conversion Agent the appropriate principal amount of
                  Debentures for exchange in accordance with this paragraph 5.
                  The Conversion Agent shall thereupon notify the Debenture
                  Issuer of the Holder's election to convert such Debentures
                  into shares of Common Stock of the Debenture Issuer. Accrued
                  Distributions will not be paid on Preferred Securities that
                  are converted, nor will any payment, allowance or adjustment
                  be made for accumulated and unpaid Distributions, whether or
                  not in arrears, on converted Preferred Securities except that
                  if any Preferred Security is converted (i) on or after a
                  record date for payment of Distributions thereon, the amount
                  of the Distributions payable on the related payment date with
                  respect to such Preferred Security shall be paid by the
                  converting Holder to the Trust and the Distributions payable
                  on the related payment date with respect to such Preferred
                  Security shall be distributed to the Holder on such record
                  date, despite such conversion, and (ii) during an Extension
                  Period and after the Institutional Trustee mails a Redemption
                  Distribution Notice with respect to the Preferred Securities
                  that are converted, accrued and unpaid Distributions through
                  the date of conversion on such Preferred Securities called for
                  redemption shall be distributed to the Holder who converts
                  such Preferred Securities, which Distribution shall be made on
                  the redemption date fixed for redemption. Except as provided
                  above, neither the Trust nor the Debenture Issuer will make,
                  or be required to make, any payment, allowance or adjustment
                  upon any conversion on account of any accumulated and unpaid
                  Distributions accrued on the Securities (including any
                  Additional Interest or Compounded Interest) surrendered for
                  conversion, or on account of any accumulated and unpaid
                  dividends on the shares of Common Stock of the Debenture
                  Issuer issued upon such conversion. The Debenture Issuer shall
                  make no payment or allowance for distributions on the shares
                  of Common Stock of the Debenture Issuer issued upon such
                  conversion, except to the extent that such shares of Common
                  Stock of the Debenture Issuer are held of record on the record
                  date for any such distributions and except as provided in
                  Section [1309] of the Indenture. Securities shall be deemed to
                  have been converted immediately prior to 5:00 p.m. (New York
                  City time) on the day on which a Conversion Request relating
                  to such Securities is received by the Trust in accordance with
                  the foregoing provision (the "Conversion Date"). The Person or
                  Persons entitled to receive the Common

                  Stock of the Debenture Issuer issuable upon conversion of the
                  Debentures shall be treated for all purposes as the record
                  holder or holders of such Common Stock of the Debenture Issuer
                  at such time. As promptly as practicable on or after the
                  Conversion Date, the Debenture Issuer shall issue and deliver
                  at the office of the Conversion Agent a certificate or
                  certificates for the number of full shares of Common Stock of
                  the Debenture Issuer issuable upon such conversion, together
                  with the cash payment, if any, in lieu of any fraction of any
                  share to the Person or Persons entitled to receive the same,
                  unless otherwise directed by the Holder in the notice of
                  conversion and the Conversion Agent shall distribute such
                  certificate or certificates to such Person or Persons.

         (c)      Each Holder of a Security by his acceptance thereof appoints 
                  [                  ] (the "Conversion Agent") for the purpose 
                  of effecting the conversion of Securities in accordance with
                  this paragraph 5. In effecting the conversion and transactions
                  described in this paragraph 5, the Conversion Agent shall be
                  acting as agent of the Holders of Securities directing it to
                  effect such conversion transactions. The Conversion Agent is
                  hereby authorized (i) to exchange Securities from time to time
                  for Debentures held by the Trust in connection with the
                  conversion of such Securities in accordance with this
                  paragraph 5 and (ii) to convert all or a portion of the
                  Debentures into Common Stock of the Debenture Issuer and
                  thereupon to deliver such shares of Common Stock of the
                  Debenture Issuer in accordance with the provisions of this
                  paragraph 5 and to deliver to the Trust a new Debenture or
                  Debentures for any resulting unconverted principal amount.

         (d)      No fractional shares of Common Stock of the Debenture Issuer
                  will be issued as a result of conversion, but in lieu thereof,
                  such fractional interest will be in cash (based on the last
                  reported sale price of the Common Stock of the Debenture
                  Issuer on the Conversion Date) by the Debenture Issuer to the
                  Trust, which in turn will make such payment to the Holder or
                  Holders of Securities so converted.

         (e)      The Debenture Issuer shall at all times reserve and keep
                  available out of its authorized and unissued Common Stock out
                  of its authorized and unissued Common Stock of the Debenture
                  Issuer, solely for




                                      I-14
<PAGE>   88

                  issuance upon the conversion of the Debentures, free from any
                  preemptive or other similar rights, such number of shares of
                  Common Stock of the Debenture Issuer as shall from time to
                  time be issuable upon the conversion of all the Debentures
                  then outstanding. Notwithstanding the foregoing, the Debenture
                  Issuer shall be entitled to deliver upon conversion of
                  Debentures, shares of Common Stock of the Debenture Issuer
                  reacquired and held in the treasury of the Debenture Issuer
                  (in lieu of the issuance of authorized and unissued shares of
                  Common Stock of the Debenture Issuer), so long as any such
                  treasury shares are free and clear of all liens, charges,
                  security interests or encumbrances. Any shares of Common Stock
                  of the Debenture Issuer issued upon conversion of the
                  Debentures shall be duly authorized, validly issued, fully
                  paid and nonassessable. The Trust shall deliver the shares of
                  Common Stock of the Debenture Issuer received upon conversion
                  of the Debentures to the converting Holder free and clear of
                  all liens, charges, security interests and encumbrances,
                  except for United States withholding taxes. Each of the
                  Debenture Issuer and the Trust shall prepare and shall use its
                  best efforts to obtain and keep in force such governmental or
                  regulatory permits or other authorizations as may be required
                  by law, and shall comply with all applicable requirements as
                  to registration or qualification of the Common Stock of the
                  Debenture Issuer (and all requirements to list the Common
                  Stock of the Debenture Issuer issuable upon conversion of
                  Debentures that are at the time applicable), in order to
                  enable the Debenture Issuer to lawfully issue Common Stock of
                  the Debenture Issuer to the Trust upon conversion of the
                  Debentures and the Trust to lawfully deliver the Common Stock
                  of the Debenture Issuer to each Holder upon conversion of the
                  Securities.

         (f)      The Debenture Issuer will pay any and all taxes that may be
                  payable in respect of the issue or delivery of shares of
                  Common Stock of the Debenture Issuer on conversion of
                  Debentures and the delivery of the shares of Common Stock of
                  the Debenture Issuer by the Trust upon conversion of the
                  Securities. The Debenture Issuer shall not, however, be
                  required to pay any tax that may be payable in respect of any
                  transfer involved in the issue and delivery of shares of
                  Common Stock of the Debenture Issuer in a name other than that
                  in which the Securities so converted were registered, and no
                  such issue or delivery shall be 




                                      I-15

                  made unless and until the person requesting such issue has
                  paid to the Trust the amount of any such tax or has
                  established to the satisfaction of the Trust that such tax has
                  been paid.

         (g)      Nothing in the preceding paragraph 5(f) shall limit the
                  requirement of the Trust to withhold taxes pursuant to the
                  terms of the Securities or as set forth in this Annex I to the
                  Declaration or the Declaration itself or otherwise require the
                  Institutional Trustee or the Trust to pay any amount on
                  account of such withholdings.

6.       Voting Rights - Preferred Securities.

         (a)      Except as provided under paragraph 6(b) and paragraph 8, in
                  the Business Trust Act and as otherwise required by law and
                  the Declaration, the Holders of the Preferred Securities will
                  have no voting rights. No vote or consent of the Holders of
                  the Preferred Securities will be required for the Trust to
                  redeem and cancel Preferred Securities or to distribute the
                  Debentures in accordance with the Declaration and the terms of
                  the Securities.

         (b)      Subject to the requirements set forth in this paragraph 6(b),
                  the Holders of a majority in liquidation amount of the
                  Preferred Securities, voting separately as a class may direct
                  the time, method, and place of conducting any proceeding for
                  any remedy available to the Institutional Trustee and 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
                  Debentures, to (i) exercise the remedies available to it under
                  the Indenture as a holder of the Debentures, (ii) waive any
                  past default and its consequences that are waivable under the
                  Indenture, (iii) exercise any right to rescind or annul a
                  declaration that the principal of all the Debentures shall be
                  due and payable, or (iv) consent to any amendment,
                  modification or termination of the Indenture or the 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 a Super Majority of
                  Debentures affected thereby, the Institutional Trustee may
                  only give such consent or take such action at the written
                  direction of the Holders of at least the proportion in
                  liquidation amount of the Preferred Securities that the
                  relevant 



                                      I-16
<PAGE>   90

                  Super Majority represents of the aggregate principal amount of
                  the Debentures outstanding. The Institutional Trustee shall be
                  under no obligation to revoke any action previously authorized
                  or approved by a vote of the Holders of the Preferred
                  Securities. Other than with respect to directing the time,
                  method and place of conducting any remedy available to the
                  Institutional Trustee or the Debenture Trustee as set forth
                  above, the Institutional Trustee shall be under no obligation
                  to take any action in accordance with the directions of the
                  Holders of the Preferred Securities under this paragraph 6
                  unless the Institutional Trustee has obtained an opinion of
                  independent tax counsel to the effect that for the purposes of
                  United States federal income tax the Trust will not be
                  classified as other than a grantor trust on account of such
                  action and each Holder will be treated as owning an undivided
                  beneficial interest in the Debentures. If the Institutional
                  Trustee fails to enforce its rights under the Debentures after
                  a Holder of Preferred Securities has made a written request,
                  such Holder of Preferred Securities may directly institute a
                  legal proceeding against the Debenture Issuer to enforce the
                  Institutional Trustee's rights under the Debentures without
                  first instituting any legal proceeding against the
                  Institutional Trustee or any other Person. Notwithstanding the
                  foregoing, if an Event of Default has occurred and is
                  continuing and such event is attributable to the failure of
                  the Debenture Issuer to pay interest or principal on the
                  Debentures on the date such interest or principal is otherwise
                  payable (or in the case of redemption on the date fixed for
                  redemption), then a Holder of Preferred Securities may
                  directly institute a proceeding for enforcement of payment to
                  such Holder (a "Direct Action") of the principal of or
                  interest on 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 Debentures. Except as provided in the preceding sentence,
                  the Holders of Preferred Securities will not be able to
                  exercise directly any other remedy available to the holders of
                  the Debentures. In connection with such Direct Action, the
                  Debenture Issuer will be subrogated to the rights of such
                  Holder of Preferred Securities under the Declaration to the
                  extent of any payment made by the Debenture Issuer to such
                  Holder of Preferred Securities in such Direct Action.

         (c)      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 Securities in the Trust 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 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.

         (d)      Notwithstanding that Holders of Preferred Securities are
                  entitled to vote or consent under any of the circumstances
                  described above, any of the Preferred Securities that are
                  owned by the Debenture Issuer or any Affiliate of the
                  Debenture Issuer 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.

7.       Voting Rights - Common Securities.

         (a)      Except as provided under paragraphs 7(b) and (c) and paragraph
                  8, in the Business Trust Act and as otherwise required by law
                  and the Declaration, the Holders of the Common Securities will
                  have no voting rights. No vote or consent of the Holders of
                  the Common Securities will be required for the Trust to redeem
                  and cancel Common Securities or to distribute the Debentures
                  in accordance with the Declaration and the terms of the
                  Securities.

         (b)      The Holders of the Common Securities are entitled, in
                  accordance with Article V of the Declaration, to vote to
                  appoint, remove or replace any Trustee or to increase or
                  decrease the number of Trustees.

         (c)      Subject to Section 2.6 of the Declaration and only after the
                  Event of Default with respect to the Preferred Securities has
                  been cured, waived, or otherwise eliminated and subject to the
                  requirements of the penultimate sentence of this paragraph
                  7(c), the


                                      I-18
<PAGE>   92

                  Holders of a majority in liquidation amount of the Common
                  Securities, voting separately as a class, may direct the time,
                  method, and place of conducting any proceeding for any remedy
                  available to the Institutional Trustee, or exercising any
                  trust or power conferred upon the Institutional Trustee under
                  the Declaration, including (i) directing the time, method,
                  place of conducting any proceeding for any remedy available to
                  the Debenture Trustee, or exercising any trust or power
                  conferred on the Debenture Trustee with respect to the
                  Debentures, (ii) waive any past default and its consequences
                  that are waivable under Section 513 of the Indenture, (iii)
                  exercise any right to rescind or annul a declaration that the
                  principal of all the Debentures shall be due and payable, or
                  (iv) consent to any amendment, modification or termination of
                  the Indenture or the Debentures where such consent shall be
                  required; provided that, where a consent or action under the
                  Indenture would require the consent or act of the Holders of a
                  Super Majority in principal amount of Debentures affected
                  thereby, the Institutional Trustee may only give such consent
                  or take such action at the written direction of the Holders of
                  at least the proportion in liquidation amount of the Common
                  Securities which the relevant Super Majority represents of the
                  aggregate principal amount of the Debentures outstanding.
                  Pursuant to this paragraph 7(c), the Institutional Trustee
                  shall not revoke any action previously authorized or approved
                  by a vote of the Holders of the Preferred Securities. Other
                  than with respect to directing the time, method and place of
                  conducting any remedy available to the Institutional Trustee
                  or the Debenture Trustee as set forth above, the Institutional
                  Trustee shall be under no obligation to take any action in
                  accordance with the directions of the Holders of the Common
                  Securities under this paragraph 7(c) unless the Institutional
                  Trustee has obtained an opinion of independent tax counsel to
                  the effect that for the purposes of United States federal
                  income tax the Trust will not be classified as other than a
                  grantor trust on account of such action and each Holder will
                  be treated as owning an undivided beneficial interest in the
                  Debentures. If the Institutional Trustee fails to enforce its
                  rights under the Debentures after a Holder of Common
                  Securities has made a written request, such Holder of Common
                  Securities may institute a legal proceeding directly against
                  the Debenture Issuer or any other Person to enforce the
                  Institutional Trustee's rights under the


                                      I-19
<PAGE>   93

                  Debentures, without first instituting any legal proceeding
                  against the Institutional Trustee or any other Person.

         (d)      Any approval or direction of Holders of Common Securities may
                  be given at a separate meeting of Holders of Common Securities
                  convened for such purpose, at a meeting of all of the Holders
                  of Securities in the Trust or pursuant to written consent. The
                  Regular Trustees will cause a notice of any meeting at which
                  Holders of Common Securities are entitled to vote, or of any
                  matter upon which action by written consent of such Holders is
                  to be taken, to be mailed to each Holder of record of Common
                  Securities. Each such notice will include a statement setting
                  forth (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.

8.       Amendments to Declaration and Indenture.

         (a)      In addition to any requirements under Section 11.1 of
                  the Declaration, if any proposed amendment to the
                  Declaration 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 Securities, whether by way of amendment
                  to the Declaration or otherwise, or (ii) the
                  dissolution, winding-up or termination of the Trust,
                  other than as described in Section 3.10 of the
                  Declaration, then the Holders of Securities as a class,
                  will be entitled to vote on such amendment or proposal
                  (but not on any other amendment or proposal) and such
                  amendment or proposal shall not be effective except
                  with the approval of the Holders of a majority  in
                  liquidation amount of the Securities affected thereby,
                  voting together as a single class; provided, however,
                  if any amendment or proposal referred to in clause (i)
                  above would adversely affect only the Preferred
                  Securities or only 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
                  Securities.

         (b)      In the event the consent of the Institutional Trustee
                  as the holder of the Debentures is required under the
                  Indenture with respect to any amendment, modification
                  or termination on the Indenture or the Debentures, the
                  Institutional Trustee shall request the written
                  direction of the Holders of the 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 Securities voting together as a single
                  class; provided, however, that where a consent under
                  the Indenture would require a Super Majority in
                  aggregate principal amount of the Debentures, the
                  Institutional Trustee may only give such consent at the
                  written direction of the Holders of at least the same
                  proportion in aggregate stated liquidation preference
                  of the Securities; provided, further, that the
                  Institutional Trustee shall not take any action in
                  accordance with the directions of the Holders of the
                  Securities under this paragraph 8(b) unless the
                  Institutional Trustee has obtained an opinion of tax
                  counsel to the effect that for the purposes of United
                  States federal income tax the Trust will not be
                  classified as other than a grantor trust on account of
                  such action.

9.       Pro Rata.

                  A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.

10.      Ranking.

                  The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where an Event of
Default occurs and is continuing under the Indenture in respect of the
Debentures held by the Institutional Trustee, the rights of Holders of the
Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights to payment
of the Holders of the Preferred Securities.

11.      Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

12.      No Preemptive Rights.

                  The Holders of the Securities shall have no preemptive rights
to subscribe for any additional securities.

13.      Miscellaneous.

                  These terms constitute a part of the Declaration.

                  The Debenture Issuer will provide a copy of the Declaration,
the Preferred Securities Guarantee or the Common Securities Guarantee (as may be
appropriate), and the Indenture to a Holder without charge on written request to
the Debenture Issuer at its principal place of business.

                             [REVERSE OF SECURITY]


     Distributions payable on each Preferred Security will be fixed at a rate
per annum of [   ]% (the "Coupon Rate") of the stated liquidation amount of $25
per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee.  Distributions in arrears
for more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law).  The term
"Distributions" as used herein includes any such interest including any
Additional Interest and Compounded Interest payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the Trust has
funds available therefor.  The amount of Distributions payable for any period
will be computed for any full quarterly Distribution period on the basis of a
360-day year of twelve 30-day months, and for any period shorter than a full
quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days elapsed
per 90-day quarter.

     Except as otherwise described below, Distributions on the Preferred
Securities will be cumulative, will accrue from the date of initial issuance and
will be payable quarterly in arrears, on the following dates, which dates
correspond to the interest payment dates on the Debentures: March 31, June 30,
September 30 and December 31 of each year, commencing on March 31, 1997, when,
as and if available for payment by the Institutional Trustee.  The Debenture
Issuer has the right at any time during the term of the Debentures to defer
interest payments from time to time by extending the interest payment period for
successive periods not exceeding 20 consecutive quarters (each, an "Extension
Period") for each such period; provided that no Extension Period may extend
beyond the maturity date of the Debentures.  As a consequence of such extension,
quarterly Distributions on the Preferred Securities would be deferred (though
such Distributions would continue to accrue with interest since interest would
continue to accrue on the Debentures) during any such extended interest payment
period.  In the event that the Debenture Issuer exercises this right, then,
during such period, (a) the Debenture Issuer 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 Debenture





                                     A-1-4
<PAGE>   101

Issuer of its obligations under any employee benefit plans or the satisfaction
by the Debenture  Issuer of its obligations pursuant to any contract or
security requiring the Debenture Issuer to purchase shares of the Common Stock,
(ii) as a result of a reclassification of the Debenture Issuer's capital stock
or the exchange or conversion of one class or series of the Debenture Issuer's
capital stock for another class or series of the Debenture Issuer's capital
stock, (iii) the purchase of fractional interests in shares of the Debenture
Issuer'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 Debenture Issuer where the dividend stock is the same
stock as that on which the dividend is paid), (b) the Debenture Issuer 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 Debenture Issuer which rank pari passu with or junior to the Debentures
and (c) the Debenture Issuer shall not make any guarantee payments with respect
to the foregoing (other than pursuant to the Preferred Securities Guarantee or
Common Securities Guarantee).  Prior to the termination of any such Extension
Period, the Debenture Issuer 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 Debentures.  Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.
Notwithstanding anything to the contrary, the Debenture Issuer shall not have
the right at any time to defer any Additional Interest, including by extending
the interest payment period.

     Distributions on the Preferred Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the relevant
record dates.  The relevant record dates shall be the March 15, June 15,
September 15 and December 15 prior to the next such succeeding payment date,
except as otherwise described in the Declaration.

     The Preferred Securities shall be redeemable as provided in the
Declaration.

     The Preferred Securities shall be convertible into shares of Common Stock
of Walbro Corporation, through (i) the exchange of Preferred Securities for a
portion of the Debentures and (ii) the immediate conversion of such Debentures
into Common Stock of Walbro Corporation, in the manner and according to the
terms set forth in the Declaration.

                             [REVERSE OF SECURITY]


   Distributions payable on each Common Security will be fixed at a rate per
annum of [   ] (the "Coupon Rate") of the stated liquidation amount of $25 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Institutional Trustee.  Distributions in arrears for more
than one quarter will bear interest thereon compounded quarterly at the Coupon
Rate (to the extent permitted by applicable law).  The term "Distributions" as
used herein includes any such interest including any Additional Interest and
Compounded Interest payable unless otherwise stated.  A Distribution is payable
only to the extent that payments are made in respect of the Debentures held by
the Institutional Trustee and to the extent the Trust has funds available
therefor.  The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

   Except as otherwise described below, Distributions on the Common Security
Securities will be cumulative, will accrue from the date of initial issuance
and will be payable quarterly in arrears, on the following dates, which dates
correspond to the interest payment dates on the Debentures:  March 31, June 30,
September 30 and December 31 of each year, commencing on March 31, 1997, when,
as and if available for payment by the Institutional Trustee.  The Debenture
Issuer has the right at any time during the term of the Debentures to defer
interest payments from time to time by extending the interest payment period
for successive periods not exceeding 20 consecutive quarters (each, an
"Extension Period") for each such period; provided that no Extension Period may
extend beyond the maturity date of the Debentures.  As a consequence of such
extension, quarterly Distributions on the Common Security Securities would be
deferred (though such Distributions would continue to accrue with interest
since interest would continue to accrue on the Debentures) during any such
extended interest payment period.  In the event that the Debenture Issuer
exercises this right, then, during such period, (a) the Debenture Issuer 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





                                     A-2-4
<PAGE>   110

acquisitions of shares of Common Stock in connection with the satisfaction by
the Debenture Issuer of its obligations under any employee benefit plans or the
satisfaction by the Debenture Issuer of its obligations pursuant to any
contract or security requiring the Debenture Issuer to purchase shares of the
Common Stock, (ii) as a result of a reclassification of the Debenture Issuer's
capital stock or the exchange or conversion of one class or series of the
Debenture Issuer's capital stock for another class or series of the Debenture
Issuer's capital stock, (iii) the purchase of fractional interests in shares of
the Debenture Issuer'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 Debenture Issuer where the dividend stock
is the same stock as that on which the dividend is paid), (b) the Debenture
Issuer 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 Debenture Issuer which rank pari passu with or junior
to the Debentures and (c) the Debenture Issuer shall not make any guarantee
payments with respect to the foregoing (other than pursuant to the Preferred
Securities Guarantee or Common Securities Guarantee).  Prior to the termination
of any such Extension Period, the Debenture Issuer 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 Debentures.  Upon the
termination of any Extension Period and the payment of all amounts then due,
the Debenture Issuer may commence a new Extension Period, subject to the above
requirements.  Notwithstanding anything to the contrary, the Debenture Issuer
shall not have the right at any time to defer any Additional Interest,
including by extending the interest payment period.

   The Common Securities shall be convertible into shares of Common Stock of
Walbro Corporation through (i) the exchange of Common Securities for a portion
of the Debentures and (ii) the immediate conversion of such Debentures into
Common Stock of Walbro Corporation, in the manner and according to the terms
set forth in the Declaration.

                         [FORM OF REVERSE OF SECURITY]

     This Security is one of a duly authorized issue of securities of the
Company designated as its [  ]% Convertible Subordinated Debenture Due 2017
(herein called the "Securities"), in aggregate principal amount of $[
] (or up to $[          ] if the over-allotment option is exercised by the
Trust in accordance with the terms and provisions of the Underwriting
Agreement), issued and to be issued under an Indenture, dated as of [
], 1997 (herein called the "Indenture"), between the Company and [
], as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.  The terms of the
Securities include those stated in the Indenture and those made part of the
Indenture by the Trust Indenture Act of 1939 (15 U.S.C. Section Section
77aaa-77bbbb) ("TIA") as in effect on the date of the Indenture.  The
Securities are subject to, and qualified by, all such terms, certain of which
are summarized hereon, and holders are referred to the Indenture and the TIA
for a statement of such terms.  No reference herein to the Indenture and no
provision of this Security or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed or to convert this Security as provided
in the Indenture.  All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.  The
Company will furnish to any Holder upon written request and without charge a
copy of the Indenture.

     (1) Interest.  The Securities shall bear interest at the rate of [  ]% per
annum, from [        ], 1997 or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, as the case may be, payable
quarterly (subject to deferral as set forth herein), in arrears, on March 31,
June 30, September 30 and December 31 (each an "Interest Payment Date") of each
year, commencing March 31, 1997, until the principal thereof is paid or made
available for payment, and they shall be paid to the Person in whose name the
Security is registered at 5:00 p.m. (New York  City time) on the

                                     B-4

<PAGE>   118


regular record date for such interest installment, which shall be the March 15,
June 15, September 15 and December 15 next preceding such Interest Payment Date
(the "Regular Record Date").  Interest will compound quarterly and will accrue
at the rate of [  ]% per annum on any interest installment in arrears for more
than one quarter or during an extension of an interest payment period as set
forth below.
        
     The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  Except as provided in the
following sentence, 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 per 90-day quarter.  In the event
that any date on which interest is payable on the Securities is not a Business
Day, then payment of interest 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 shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.

     If at any time while the Institutional Trustee is the Holder of any
Securities, the Trust or the Institutional Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any such case, the Company shall pay as additional interest
("Additional Interest") on the Securities held by the Institutional Trustee,
such amounts as shall be required so that the net amounts received and retained
by the Trust and the Institutional Trustee after paying any such taxes, duties,
assessments or other governmental charges will be not less than the amounts the
Trust and the Institutional Trustee would have received had no such taxes,
duties, assessments or other governmental charges been imposed.

     The principal of and interest on the Securities shall be payable at the
office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company

                                     B-5

<PAGE>   119


payment of interest may be made by check mailed to the address  of the Person
entitled thereto as such address shall appear in the Security Register.
        
     (2)  Option to Extend Interest Payment Period.  The Company shall have the
right at any time during the term of the Securities to defer interest payments
(including Additional Payments) by extending the interest payment period for a
period (each, an "Extension Period") not exceeding 20 consecutive quarters;
provided, no Extension Period may extend beyond the maturity date of the
Securities and at the end of which Extension Period, the Company shall pay all
interest then accrued and unpaid (including Additional Interest) together with
interest thereon compounded quarterly at the rate specified for the Securities
to the extent permitted by applicable law ("Compounded Interest"); provided,
that during any Extension Period, the Company shall (i) not declare or pay
dividends on, or make any distributions with respect to, or redeem or purchase
or acquire, or liquidation payments with respect to, or redeem, purchase or
acquire any of its capital stock (other than (A) 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, (B) 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 (C) 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 (D) stock dividends paid by the Company where the dividend stock
is the same as that on which the dividend is paid), (ii) 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 that
rank pari passu with or junior to the Securities and (iii) 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 such 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 Securities.  Upon the termination of any
Extension Period and the payment of 

                                     B-6

<PAGE>   120


all amounts then due, the Company may commence a new Extension Period, subject
to the  above requirements.  No interest during an Extension Period shall be
due and payable.  Notwithstanding anything to the contrary, the Company shall
not have the right at any time to defer any Additional Interest, including by
extending the interest payment period.
        
     If the Institutional Trustee is the sole Holder of the Securities at the
time the Company selects an Extension Period, the Company shall give written
notice to the Regular Trustees, the Institutional Trustee and the Trustee 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) if the Preferred Securities
are listed on the Nasdaq National Market or any other stock exchange or
quotation system, the date the Regular Trustees are required to give notice to
the Nasdaq National Market (or other applicable self-regulatory organization)
or to holders of the Preferred Securities of the record date or the date such
distributions would be payable if not for such Extension Period, but in any
event not less than one Business Day prior to such record date.

     If the Institutional Trustee is not the sole Holder of the Securities at
the time the Company selects an Extension Period, the Company shall give the
Holders of the Securities and the Trustee written notice of its selection of
such Extension Period at least 10 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 Nasdaq National Market (or any applicable
self-regulatory organization) or to Holders of the Securities on the record or
payment date of such related interest payment.

     The quarter in which any notice is given pursuant to paragraphs second and
third of this Section 2 shall be counted as one of the 20 quarters permitted in
the maximum Extension Period permitted under paragraph one of this Section 2.

     (3)  Paying Agent and Security Registrar.  The Trustee will act as Paying
Agent, Security Registrar and Conversion Agent.  The Company may change any
Paying Agent, Security Registrar, co-registrar or Conversion Agent without
prior notice.  The Company or any of its Affiliates may act in any such
capacity.

                                     B-7

     (4) Redemption.  The Securities are redeemable, in whole or in part, at any
time or from time to time after  [          ], 2000 at the redemption prices
(expressed as a percentage of the principal amount of Securities) specified
below for the 12 month period commencing [          ] in the year indicated ([
], in the case of 2000), if redeemed during the 12-month period
beginning December 31:


                                           Percentage of
                                             Principal
          Year                                 Amount
          ----                            -----------------

          2000                                     %
          2001
          2002
          2003
          2004
          2005
          2006
          2007 and thereafter                 100.0%

plus, in each case, accrued and unpaid interest (including Additional Payments,
if any) to the Redemption Date.  On and after the Redemption Date, interest
ceases to accrue on the Securities or portions of them called for redemption.

     The Securities are subject to redemption in whole or in part), at any time
within 90 days, under certain circumstances if a Tax Event (as defined in the
Declaration) shall occur and be continuing, at a redemption price equal to 100%
of the principal amount thereof plus accrued but unpaid interest (including
Additional Payments, if any) to the Redemption Date.  On and after the
Redemption Date, interest ceases to accrue on the Securities or portions of
them called for redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at such Holder's address appearing in
the Security Register.  The Securities in denominations larger than $25 may be
redeemed in part but only in integral multiples of $25.  In the event of a
redemption of less than all of the Securities, the Securities will be chosen
for redemption by the Trustee in accordance with the Indenture.

                                     B-8

<PAGE>   122

     If this Security is redeemed subsequent to a Regular Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the person in
whose name this  Security is registered at the close of business on such record
date.

     (5)  Sinking Fund.  The Securities are not entitled to the benefit of any
sinking fund.

     (6)  Subordination.  The payment of the principal of, premium, if any, and
interest (including Additional Payments, if any) on all Securities is
subordinated and junior in right of payment to the prior payment in full of all
existing and future Senior Indebtedness, whether outstanding at the date of
this Indenture or thereafter incurred.  Each holder, by accepting a Security,
agrees to such subordination and authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee as its attorney-in-fact for
such purpose.

     (7)  Conversion.  The Holder of any Security has the right, exercisable
at any time after [           ], 1997 and on or before 5:00 p.m. (New York City
time) on the Business Day immediately preceding the date of repayment of such
Securities, whether at maturity or upon redemption (either at the option of the
Company or pursuant to a Tax Event), to convert the principal amount thereof
(or any portion thereof that is an integral multiple of $25) into fully paid
and nonassessable shares of Common Stock of the Company at an initial
conversion rate of [     ] shares of Common Stock for each $25 in aggregate
principal amount of Securities (equal to a conversion price of $[       ] per
share of Common Stock), subject to adjustment under certain circumstances.  The
number of shares issuable upon conversion of a Security is determined by
dividing the principal amount of the Security converted by the conversion price
in effect on the Conversion Date.  No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.  The
outstanding principal amount of any Security shall be reduced by the portion of
the principal amount thereof converted into shares of Common Stock.
        
     To convert a Security, a Holder must (i) complete and sign a conversion
notice substantially in the form attached hereto, (ii) surrender the Security
to a Conversion Agent, (iii) furnish appropriate endorsements or transfer
documents if 

                                     B-9

<PAGE>   123

required by the Security Registrar or Conversion Agent and (iv) pay any
transfer or similar tax, if required.  If a Notice of Conversion is delivered
on or after the Regular Record Date and prior to the subsequent Interest
Payment Date, the Holder shall be required to pay to the Company the interest
payment on the  subsequent Interest Payment Date and, will be entitled to
receive the interest payable on the subsequent Interest Payment Date, on the
portion of Securities to be converted notwithstanding the conversion thereof
prior to such Interest Payment Date.  Notwithstanding the foregoing, if, during
an Extension Period, a notice of redemption is mailed pursuant to Section 11.06
of the Indenture and a Security is converted after such mailing but prior to
the relevant Redemption Date, all accrued but unpaid interest (including
Additional Payments, if any) through the date of conversion shall be paid to
the holder of such Security on the Redemption Date.  Except as otherwise
provided in the immediately preceding two sentences, in the case of any
Security which is converted, interest whose Stated Maturity is after the date
of conversion of such Security shall not be payable, and the Company shall not
make nor be required to make any other payment, adjustment or allowance with
respect to accrued but unpaid interest (including Additional Payments, if any)
on the Securities being converted, which shall be deemed to be paid in full. If
any Security called for redemption is converted, any money deposited with the
Trustee or with any Paying Agent or so segregated and held in trust for the
redemption of such Security shall (subject to any right of the Holder of such
Security or any Predecessor Security to receive interest as provided in the
last paragraph of Section 3.07 of the Indenture and this paragraph) be paid to
the Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.
        
     (8)  Registration, Transfer, Exchange and Denominations.  As provided in
the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon
surrender of this Security for registration of transfer at the office or agency
of the Company, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.
        
                                     B-10
        
<PAGE>   124

     The Securities are issuable only in registered form without coupons in
denominations of $25 and integral multiples thereof.  No service charge shall
be made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.  Prior to due presentment of this
Security for registration of transfer,  the Company, the Trustee and any agent
of the Company or the Trustee may treat the Person in whose name this Security
is registered as the owner hereof for all purposes, whether or not this
Security be overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary.  In the event of redemption or
conversion of this Security in part only, a new Security or Securities for the
unredeemed or unconverted portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

     (9)  Persons Deemed Owners.  Except as provided in the Indenture, the
registered Holder of a Security may be treated as its owner for all purposes.

     (10) Unclaimed Money.  If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request.  After that, holders of
Securities entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

     (11) Defaults and Remedies.  The Securities shall have the Events of
Default as set forth in Section 5.01 of the Indenture.  Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the holders of at least 25% in
aggregate principal amount of the then outstanding Securities by notice to the
Company and the Trustee may declare all the Securities to be due and payable
immediately.

     The holders of a majority in principal amount of the Securities then
outstanding by written notice to the Trustee may rescind an acceleration and
its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration.  Holders may not enforce the Indenture or the 

                                     B-11

<PAGE>   125


Securities except as provided in the Indenture.  Subject to certain
limitations, holders of a majority in principal amount of the then outstanding
Securities issued under the Indenture may direct the Trustee in its exercise of
any trust or power. The Securities are unsecured general obligations of the
Company.  The Company must furnish annually compliance certificates to the
Trustee.  The above description of Events of Default and remedies is qualified
by reference to, and subject in  its entirety by, the more complete description
thereof contained in the Indenture.
        
     (12)  Amendments, Supplements and Waivers.  The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders of the Securities under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in aggregate
principal amount of the Securities at the time Outstanding.  The Indenture also
contains provisions permitting the Holders of specified percentages in
aggregate principal amount of the Securities at the time Outstanding, on behalf
of the Holders of all the Securities, to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.
        
     (13) Trustee Dealings with the Company.  The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Securities and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA.  Any Agent may do the same with like rights.
        
     (14) No Recourse Against Others.  A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation.  Each Holder of the Securities by accepting a Security waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

     (15) Governing Law.  THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE SECURITIES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

     (16) Authentication.  The Securities shall not be valid until
authenticated by the manual signature of an authorized officer of the Trustee
or an authenticating agent.

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

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

SECTION 1.04.   Acts of Holders; Record Dates.

          (a)     Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

          (b)     The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such

law to take acknowledgments of deeds, certifying that the individual 

<PAGE>   22

                                      -14-

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

          (c)     The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Outstanding Securities entitled to give, make or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders.  If
not set by the Company prior to the first solicitation of a Holder made by any
Person in respect of any such action, or, in the case of any such vote, prior to
such vote, the record date for any such action or vote shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 7.01) prior to such first solicitation or vote, as
the case may be.  With regard to any record date, only the Holders on such date
(or their duly designated proxies) shall be entitled to give or take, or vote
on, the relevant action.

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

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

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

SECTION 1.05.   Notices, Etc., to Trustee and the Company.

or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

          (a)     the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust & Agency Department, or

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

SECTION 1.06.   Notice to Holders; Waiver.

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at such Holder's address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice.  In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders.  Any notice when
mailed to a Holder in the aforesaid manner shall be conclusively deemed to have
been received by such Holder whether or not actually received by such Holder.
Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such  filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be 

<PAGE>   24
                                      -16-

impracticable to give such notice by mail, then such notification as shall be
made with the approval of the Trustee shall constitute a sufficient notification
for every purpose hereunder.

SECTION 1.07.   Conflict with Trust Indenture Act.

          If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

SECTION 1.08.   Effect of Headings and Table of Contents.

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

SECTION 1.09.   Successors and Assigns.

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

SECTION 1.10.   Separability Clause.

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

SECTION 1.11.   Benefits of Indenture.

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

SECTION 1.13   Legal Holidays.

          In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert his Securities shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal or conversion of the Securities need not be made on such date, but may
be made on the next succeeding Business Day (except that, if such Business Day
is in the next succeeding calendar year, such Interest Payment Date, Redemption
Date or Stated Maturity, as the case may be, shall be the immediately preceding
Business Day) with the same force and effect as if made on the Interest Payment
Date or Redemption Date, or at the Stated Maturity or on such last day for

after such Interest Payment Date, Redemption Date or Stated Maturity, as the

be substantially in the form of Exhibit A, which is hereby incorporated in and
expressly made a part of this Indenture.  The Securities may have letters,
numbers, notations or other marks of identification or designation and such

shall furnish any such legend not contained in Exhibit A to the Trustee in
writing.  Each Security shall be dated the date of  its authentication.  The

their execution and delivery of this Indenture, expressly agree to such terms

steel engraved borders or may be produced in any other manner permitted by the
rules of any securities exchange on which the Securities may be listed, all as

SECTION 2.02.   Initial Issuance to Institutional Trustee.

          The Securities initially issued to the Institutional Trustee of the
Trust shall be in the form of one or more individual certificates in definitive,
fully registered form without coupons.

                                 ARTICLE THREE

                                 The Securities

SECTION 3.01.   Title and Terms.

          The aggregate principal amount of Securities that may be authenticated
and delivered under this Indenture is limited to $[          ] (or up to $[ ] if
the over-allotment option is exercised in full in accordance with the terms and
provisions of the Underwriting Agreement), except for Securities authenticated
and delivered upon registration of transfer of, or in exchange for, or in lieu
of, other Securities pursuant to Section 3.04, 3.05, 3.06, 9.06, 11.09 or 13.01.

          The Securities shall be known and designated as the "[   ]% 
Convertible Subordinated Debentures Due 2017" of the Company.  Their
Stated Maturity shall be [          ], 2017, and they shall bear interest at
the rate of [   ]% per annum, from [           ], 1997 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, as
the case may be, payable quarterly (subject to deferral as set forth herein),
in arrears, on March 31, June 30, September 30 and December 31 (each an
"Interest Payment Date") of each year, commencing March 31, 1997, until the
principal  thereof is paid or made available for payment, and they shall be
paid to the Person in whose name the Security is registered at 5:00 p.m. (New
York City time) on the regular record date for such interest installment, which
shall be the March 15, June 15, 

<PAGE>   27

                                      -19-

September 15 and December 15 next preceding such Interest Payment Date (the
"Regular Record Date").  Interest will compound quarterly and will accrue at the
rate of [   ]% per annum on any interest installment in arrears for more than
one quarter or during an extension of an interest payment period as set forth in
Section 3.12 hereof.

          The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest in computed, will be computed on the
basis of the actual number of days elapsed per 90-day quarter.  In the event
that any date on which interest is payable on the Securities is not a Business
Day, then payment of interest 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 shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

          If at any time while the Institutional Trustee is the Holder of any
Securities, the Trust or the Institutional Trustee is required to pay any taxes,
duties, assessments or governmental charges of whatever nature (other than
withholding taxes) imposed by the United States, or any other taxing authority,
then, in any such case, the Company will pay as additional interest ("Additional
Interest") on the Securities held by the Institutional Trustee, such amounts as
shall be required so that the net amounts received and retained by the Trust and
the Institutional Trustee after paying any such taxes, duties, assessments or
other governmental charges will be not less than the amounts the Trust and the
Institutional Trustee would have received had no such taxes, duties, assessments
or other governmental charges been imposed.

          The principal of and interest on the Securities shall be payable at
the office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of  payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
check mailed to the address 

<PAGE>   28

                                      -20-

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

          The Securities shall be redeemable as provided in Article Eleven
hereof.

          The Securities shall be subordinated in right of payment to Senior
Indebtedness as provided in Article Twelve hereof.

          The Securities shall be convertible as provided in Article Thirteen
hereof.

SECTION 3.02.   Denominations.

          The Securities shall be issuable only in registered form without
coupons and only in denominations of $25 and integral multiples thereof.

SECTION 3.03.    Execution, Authentication, Delivery
                 and Dating.
                 

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries.  The signature of any of these
officers on the Securities may be manual or facsimile.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

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

          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless 

<PAGE>   29

                                      -21-

there appears on such Security a certificate of authentication substantially in
the form provided for herein executed by the Trustee by manual signature, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

SECTION 3.04.   Temporary Securities.

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

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.02, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and make
available for delivery in exchange therefor a like principal amount of
definitive Securities of authorized denominations.  Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.


SECTION 3.05.    Registration, Registration of Transfer and
                 Exchange.
                 

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.02 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed  "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

<PAGE>   30
                                      -22-


          Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 10.02 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate principal
amount.

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

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

          Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 9.06, 11.09 or 13.01 not involving any
transfer.

SECTION 3.06.    Mutilated, Destroyed, Lost and Stolen
                 Securities.
                 

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

<PAGE>   31


                                      -23-

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

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


SECTION 3.07.    Payment of Interest; Interest Rights
                 Preserved.
                 

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at 5:00 p.m. (New York City time) on the Regular Record Date.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest 
<PAGE>   32

                                      -24-

Payment Date (herein called "Defaulted Interest") shall forthwith cease to be
payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (a) or (b) below:

          (a)     The Company may elect to make payment of any Defaulted
     Interest to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at 5:00 p.m. (New York City time) on
     a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner.  The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security and the date of the proposed payment, and at the same time
     the Company shall deposit with the Trustee an amount of money equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as in this Clause (a) provided. Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the Trustee
     of the notice of the proposed payment.  The Trustee shall promptly notify
     the Company of such Special Record Date and, in the name and at the expense
     of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder at his address as it appears in
     the Security Register, not less than 10 days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such Defaulted Interest
     shall be paid to the Persons in whose names the Securities (or their
     respective Predecessor Securities) are registered at 5:00 p.m. (New York
     City time) on such Special Record Date and shall no longer be payable
     pursuant to the following Clause 

          (b)     The Company may make payment of any Defaulted Interest in 
     any other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and, if so
     listed, upon such 

<PAGE>   33

                                      -25-

     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this Clause (b),
     such manner of payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section 3.07, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue (including in each such case Additional
Payments, if any), which were carried by such other Security.

          In the case of any Security which is converted after any Regular
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Security whose Maturity is prior to such Interest Payment Date),
interest whose Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at 5:00 p.m. (New York City time) on such Regular Record Date.
Notwithstanding the foregoing, if, during an Extension Period, a notice of
redemption is mailed pursuant to Section 11.06 and a Security is converted after
such mailing but prior to the relevant Redemption Date, all accrued but unpaid
interest (including Additional Payments, if any) through the date of conversion
shall be paid to the holder of such Security on the Redemption Date. Except as
otherwise expressly provided in the immediately preceding two sentences, in the
case of any Security that is converted prior to any Regular Record Date,
interest whose Stated Maturity is after the date of conversion of such Security
shall not be payable, and the Company shall not make nor be required to make any
other payment, adjustment or allowance with respect to accrued but unpaid
interest  (including Additional Payments, if any) on the Securities being
converted, which shall be deemed to be paid in full.  Subject to any right of
the Holder of such Security or any Predecessor Security to receive interest as
provided in this paragraph and the second paragraph of Clause (a) of Section
13.02, the Company's delivery upon conversion of the fixed number of shares of
Common Stock into which the Securities are convertible (together with the cash
payment, if any, in lieu of fractional shares) shall be deemed to satisfy the
Company's obligation to pay the principal amount at Maturity of the portion of
Securities so converted and any unpaid interest (including Additional Payments,
if any) accrued on such Securities at the time of such 

<PAGE>   34

                                      -26-

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

SECTION 3.08.   Persons Deemed Owners.

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 3.07) interest (including Additional Payments, if any) on such Security
and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

SECTION 3.09.   Cancellation.

          All Securities surrendered for payment, redemption, registration of
transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it.  The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture.  All cancelled
Securities held by the Trustee shall be disposed of as directed by a Company
Order; provided, however, that the Trustee shall not be required to destroy the
certificates representing such cancelled Securities.

SECTION 3.10.   Right of Setoff.

          Notwithstanding anything to the contrary in this Indenture, the
Company shall have the right to set off any payment it is otherwise required to
make hereunder to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a payment under the Guarantee.

<PAGE>   35
                                      -27-


SECTION 3.11.  CUSIP Numbers.

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

SECTION 3.12.   Option to Extend Interest Payment Period.

          (a)   The Company shall have the right at any time, and from time to
time during the term of the Securities, to defer interest payments (including
Additional Payments) by extending the interest payment period for a period
(each, an "Extension Period") not exceeding 20 consecutive quarters; provided,
no Extension Period may extend beyond the maturity date of the Securities, and
at the end of which Extension Period, the Company shall pay all interest then
accrued and unpaid (including Additional Interest) together with interest
thereon compounded quarterly at the rate specified for the Securities to the
extent permitted by applicable law ("Compounded Interest"); provided, that
during any Extension Period, the Company shall (i) 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 (A) 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, (B) 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 (C) 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 (D) stock dividends paid by the Company where the dividend stock is
the same as that on which the dividend is paid), (ii) 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 that
rank pari passu with or 

<PAGE>   36

                                      -28-

junior to the Securities and (iii) 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 such
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 Securities.  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 during an Extension
Period shall be due and payable. Notwithstanding any other provision in this
Indenture to the contrary, the Company shall not have the right at any time to
defer any Additional Interest, including by extending the interest payment
period.

          (b)     If the Institutional Trustee is the sole Holder of the
Securities at the time the Company selects an Extension Period, the Company
shall give written notice to the Regular Trustees, the Institutional Trustee and
the Trustee 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) if the
Preferred Securities are quoted for trading on the Nasdaq National Market or any
other stock exchange or quotation system, the date the Regular Trustees are
required to give notice to the Nasdaq National Market (or other applicable
self-regulatory organization) or to holders of the Preferred Securities of the
record date or the date such distributions would be payable if not for such
Extension Period, but in any event not less than one Business Days prior to such
record date.

          (c)     If the Institutional Trustee is not the sole Holder of the
Securities at the time the Company selects an Extension Period, the Company
shall give the Holders of the Securities and the Trustee written notice of its
selection of such Extension Period at least 10 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 Nasdaq National Market (or any
applicable self-regulatory organization) or to Holders of the Securities on the
record or payment date of such related interest payment.

          (d)     The quarter in which any notice is given pursuant to
paragraphs (b) and (c) hereof shall be counted as one of 

<PAGE>   37
                                      -29-


the 20 quarters permitted in the maximum Extension Period permitted under
paragraph (a) hereof.


SECTION 3.13.    Paving Agent, Security Registrar and
                 Conversion Agent.

          The Trustee will initially act as Paying Agent, Security Registrar and
Conversion Agent.  The Company may change any Paying Agent, Security Registrar,
co-registrar or Conversion Agent without prior notice.  The Company or any of
its Affiliates may act in any such capacity.  The Trustee is entitled to the
protections of Article Six in its capacity as Paying Agent, Registrar and
Conversion Agent.


SECTION 3.14.    Global Security. 

          (a)    In connection with a Dissolution Event,

          (1)   the Securities in certificated form may be presented to the
     Trustee by the Institutional Trustee in exchange for a global Security in
     an aggregate principal amount equal to the aggregate principal amount of
     all outstanding Securities (a "Global Security"), to be registered in the
     name of the Depositary, or its nominee, and delivered by the Trustee to the
     Depositary for crediting to the accounts of its participants pursuant to
     the instructions of the Regular Trustees.  The Company upon any such
     presentation shall execute a Global Security in such aggregate principal
     amount and deliver the same to the Trustee for authentication and delivery
     in accordance with this Indenture. Payments on the Securities issued as a
     Global Security will be made to the Depositary; and

          (2)     if any Preferred Securities are held in non-book-entry
     certificated form, the Securities in certificated form may be presented to
     the Trustee by the Institutional Trustee and any Preferred Security
     Certificate which represents Preferred Securities other than Preferred
     Securities held by the Depositary or its nominee ("Non-Book-Entry Preferred
     Securities") will be deemed to represent beneficial interests in Securities
     presented to the Trustee by the Institutional Trustee having an aggregate
     principal amount equal to the aggregate liquidation amount of the
     Non-Book-Entry Preferred Securities until such Preferred Security
     Certificates are presented to the Security Registrar for transfer or
     reissuance, at which time such Preferred Security Certificates will be
     cancelled and a

<PAGE>   38
                                      -30-


     Security, registered in the name of the holder of the Preferred Security
     Certificate or the transferee of the holder of such Preferred Security
     Certificate, as the case may be, with an aggregate principal amount equal
     to the aggregate liquidation amount of the Preferred Security Certificate
     cancelled, will be executed by the Company and delivered to the Trustee for
     authentication and delivery in accordance with this Indenture.  On issue of
     such Securities, Securities with an equivalent aggregate principal amount
     that were presented by the Institutional Trustee to the Trustee will be
     deemed to have been cancelled.

          (b)   A Global Security may be transferred, in whole but not in part,
only to another nominee of the Depositary, or to a nominee of such successor
Depositary.

          (c)   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 Event of Default with respect to such
Securities, as the case may be, the Company will execute, and, subject to
Article Three of this Indenture, the Trustee, upon written notice from the
Company and receipt of a Company Order, will authenticate and deliver the
Securities in definitive registered form without coupons, in  authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security.  In
addition, upon an Event of Default or if the Company may at any time determine
that the Securities shall no longer be represented by a Global Security, in such
event the Company will execute, and subject to Section 3.05 of this Indenture,
the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and make available for delivery
the Securities in definitive registered form without coupons, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security. Upon the
exchange of the Global Security for such Securities in definitive registered
form without coupons, in authorized denominations, the Global Security shall be
cancelled by the Trustee.  Such Securities in definitive

<PAGE>   39
                                      -31-

registered form issued in exchange for the Global Security shall be registered
in such names and in such authorized denominations as the Depositary, pursuant
to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee.  The Trustee shall deliver such Securities to the
Depositary for delivery to the Persons in whose names such Securities are so
registered.

          (d)   Every Global Security authenticated and delivered hereunder
shall bear a legend in substantially the following form, in capital letters and
bold face type:

     THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
     HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
     NOMINEE THEREOF.  THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART
     FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN
     PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
     DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES
     DESCRIBED IN THE INDENTURE.

          (e)   If the Depositary is the Depository Trust Company, the Global
Security authenticated and delivered hereunder shall also bear a legend in
substantially the following form, in capital letters and bold face type:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED SIGNATORY OF THE
     DEPOSITORY TRUST COMPANY ("DTC") TO THE COMPANY OR ITS AGENT FOR
     REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE  ISSUED
     IS REGISTERED IN THE NAME OF CEDE & CO.  OR IN SUCH OTHER NAME AS IS
     REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE
     TO CEDE & CO.  OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
     REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE
     OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED
     OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

                           Satisfaction and Discharge

SECTION 4.01.   Satisfaction and Discharge of Indenture.

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

          (a)  either

               (i)  all Securities theretofore authenticated and delivered

          Additional Payments, if any) to the date of such deposit (in the case
          of Securities which have become due and payable) or to the Stated
          Maturity or  Redemption Date, as the case may be, along with an

     termination of the Trust, except in connection with (i) the distribution of
     Securities to holders of Preferred Securities in liquidation of the Trust
     upon the redemption of all of the outstanding Preferred Securities of the
     Trust or (ii) certain mergers, consolidations or amalgamations, each as
     permitted by the Declaration.


SECTION 5.02.    Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities may declare the principal of all the
Securities and any other amounts payable hereunder to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal and all accrued
interest shall become immediately due and payable.

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

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

               (i)  all overdue interest (including Additional Payments, if any)
          on all Securities,

<PAGE>   44

                                      -36-

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

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

          and

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

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


SECTION 5.03.  Collection of Indebtedness and Suits for 
               Enforcement by Trustee.

          The Company covenants that if:


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

          (b)  default is made in the payment of the principal of any Security
     at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest (including Additional Payments, if any)
and, to the  extent that payment thereof shall be legally enforceable, interest
on any overdue principal and on any overdue interest (including Additional
Payments, if any), at the rate borne by the Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce 

<PAGE>   45

                                      -37-

its rights and the rights of the Holders by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

SECTION 5.04.   Trustee May File Proofs of Claim.

          In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding.  In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.


SECTION 5.05.    Trustee May Enforce Claims
                 Without Possession of Securities.

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

<PAGE>   46

                                      -38-

Trustee, its agents and counsel, be for the ratable benefit of the Holders of
the Securities in respect of which such judgment has been recovered.

SECTION 5.06.   Application of Money Collected.

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

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

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

SECTION 5.07.   Limitation on Suits.

          Subject to Section 5.16, no Holder of any Security shall have any
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

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

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

<PAGE>   47
                                      -39-


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

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

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

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


SECTION 5.08.    Unconditional Right of Holders to Receive
                 Principal and Interest and Convert.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 3.07) interest
(including Additional Payments, if any) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to convert such Security in accordance with Article
Thirteen and to institute suit for the enforcement of any such payment and right
to convert, and such rights shall not be impaired without the consent of such
Holder.

SECTION 5.09.   Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their 

<PAGE>   48

                                      -40-

former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

SECTION 5.10.   Rights and Remedies Cumulative.

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

SECTION 5.11.   Delay or Omission Not Waiver.

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

SECTION 5.12.   Control by Holders.

          The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee; provided, that

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

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

                                      -41-


SECTION 5.13.   Waiver of Past Defaults.

          Subject to Section 9.02 hereof, the Holders of not less than a
majority in principal amount of the Outstanding Securities may on behalf of the
Holders of all the Securities waive any past default hereunder and its
consequences, except a default

          (a)   in the payment of the principal of, premium, if any, or
     interest (including Additional Payments, if any) on any Security (unless
     such default has been cured and a sum sufficient to pay all matured
     installments of interest and principal due otherwise than by acceleration
     has been deposited with the Trustee); or

          (b)  in respect of a covenant or provision hereof that under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security affected; provided, however, that if the
     Securities 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 Security is required, such waiver
     shall not be effective until each holder of the Trust Securities shall have
     consented to such waiver.

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

SECTION 5.14.   Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a  court may require any party litigant in such suit
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in the
Trust Indenture Act; provided, that neither this Section nor the Trust Indenture
Act shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company

<PAGE>   50
                                      -42-

or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest (including Additional Payments, if any) on any
Security or to convert any Security in accordance with Article Thirteen.

SECTION 5.15.   Waiver of Stay or Extension Laws.

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

SECTION 5.16.   Enforcement by Holders of Preferred Securities.

          Notwithstanding the foregoing, if an 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 Securities 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 Securities.  The Company may not
amend this 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 Securities (including
Additional Payments, if any) 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 Securities.

the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur personal financial liability in the performance of any of its duties or in
the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that the repayment of such funds or liability is not reasonably
assured to it under the terms of this Indenture or indemnity reasonably
satisfactory to the Trustee against such risk or liability is not reasonably
assured to it. Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 6.01.

SECTION 6.02.   Notice of Defaults.

such notice to Holders shall be given until at least 30 days after the
occurrence thereof.  For the purpose of this Section 6.02, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default.

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

          (d)   the Trustee may consult with counsel of its choice and the

     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

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

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

          The provisions of this Section shall survive the termination of this
Indenture.

SECTION 6.08.   Disqualification; Conflicting Interests.

SECTION 6.10.   Resignation and Removal; Appointment of
                Successor.

          (b)  The Trustee may resign at any time by giving written notice

          (d)    If at any time:

          (i)    the Trustee shall fail to comply with Section 6.08 after
     written request therefor by the Company or by  any Holder who has been a
     bona fide Holder of a Security for at least six months, or

          (ii)   the Trustee shall cease to be eligible under Section 6.09 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

          (iii)  the Trustee shall become incapable of acting or shall be
     adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of the Trustee 

<PAGE>   56

     conservation or liquidation,

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

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

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 1.06.  Each notice shall include the

SECTION 6.11.   Acceptance of Appointment by Successor.

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; provided, that on request of the Company or
the successor Trustee, such retiring Trustee shall, upon payment of its 

<PAGE>   57

                                      -49-

charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.  Upon request of any such successor
Trustee, the Company shall execute any and all instruments required to more
fully and certainly vest in and confirm to such successor Trustee all such
rights, powers and trusts.

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


SECTION 6.12.   Merger, Conversion, Consolidation 
                or Succession to Business.

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


SECTION 6.13.    Preferential Collection of Claims Against 
                 Company.

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

supplemental hereto.  If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled

<PAGE>   64
                                      -56-

shall in any manner relieve the Company of its obligation to maintain an office
or agency in the United States for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

SECTION 10.03.    Money for Security Payments to Be Held 
                  in Trust.


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

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

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

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

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or interest on
(including Additional Payments, if any) any Security and remaining unclaimed for
two years 

<PAGE>   67

                                      -59-

after such principal or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of any such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease.

SECTION 10.04.   Statement by Officers as to Default.

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


SECTION 10.05.    Limitation on Dividends; Covenants as to 
                  the Trust.

          (a)     The Company covenants that so long as the Securities 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
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 Securities by extending
the interest payment period and such period, or any extension thereof, shall be
continuing, then the Company shall (A) not 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 (w)
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, (x) 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, (y) the purchase of fractional
interests in shares of the Company's 

<PAGE>   68

                                      -60-

capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged or (z) stock dividends paid
by the Company where the dividend stock is the same stock as that on which the
dividend is paid), (B) 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 that rank pari passu with or junior
to the Securities and (C) not make any guarantee payments with respect to the
foregoing (other than pursuant to the Guarantee).

          (b)  The Company also covenants and agrees (i) that it shall directly
or indirectly maintain 100% ownership of the Common Securities of the Trust;
provided, however, that any permitted successor of the Company hereunder may
succeed to the Company's ownership of such Common Securities and (ii) that it
shall use its reasonable efforts, consistent with the terms and provisions of
the Declaration, to cause the Trust (x) to remain a statutory business trust,
except in connection with the distribution of the Securities 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 amalgamations,
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.

SECTION 10.06.   Payment of Expenses of the Trust.

          In connection with the offering, sale and issuance of the Securities
to the Institutional Trustee in connection with  the sale of the Trust

          (b)  If a partial redemption of the Securities would result in the
delisting of the Preferred Securities issued by the Trust from any national

may only redeem the Securities in whole.


SECTION 11.02.    Tax Event Optional Redemption.

          If a Tax Event has occurred and is continuing and:

          (a)   the Company has received a Redemption Tax Opinion; or

          (b)  after receiving a Dissolution Tax Opinion, the Regular Trustees
     shall have been informed by tax counsel rendering the Dissolution Tax
     Opinion that a No Recognition Opinion cannot be delivered to the Regular
     Trustees,

then, notwithstanding Section 11.01(a) but subject to Section 11.01(b), the
Company shall have the right upon not less than 30 days nor more than 60 days
notice to the Holders of the Securities to redeem the Securities in whole or in
part for cash at a redemption price equal to 100% of the principal amount of the
Securities plus accrued and unpaid interest (including Additional Payments), if
any, within 90 days following the occurrence of such Tax Event (the "90-day

Company or the Trust the opportunity to eliminate within such 90-Day Period, the
Tax Event by taking some ministerial action ("Ministerial Action"), such as
filing a form or making an election, or pursuing some other similar reasonable
measure which, in the sole judgment of the Company, has or will cause no adverse
effect on the Company, the Trust or the Holders of the Trust Securities, the
Company or the Trust shall pursue such Ministerial Action or other measure in
lieu of redemption, and provided, further, that the Company shall have no right
to redeem the Securities while the Trust is pursuing any Ministerial Action or
other similar measure pursuant to its obligations under the Declaration.

SECTION 11.03.  Applicability of Article.

SECTION 11.04.   Election to Redeem; Notice to Trustee.

          The election of the Company to redeem Securities pursuant to Section
11.01 or 11.02 shall be evidenced by a Board Resolution.  In case of any
redemption at the election of the Company, the Company shall, at least 45 days
and no more than 90 days prior to the Redemption Date fixed by the Company,
notify the Trustee in writing of such Redemption Date and of the principal
amount of Securities to be redeemed and provide a copy of the notice of

11.05.


SECTION 11.05.    Selection by Trustee of Securities to Be 
                  Redeemed.

          If less than all the Securities are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 45 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities not previously called for
redemption, by such method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions (equal to $25 or
any integral multiple thereof) of the principal amount of the Securities.

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

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

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

SECTION 11.06.   Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at such Holder's address
appearing in the Security Register.

          (b)      the Redemption Price,

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

          (d)      the place or places where such Securities are to be
surrendered for payment of the Redemption Price.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 11.07.   Deposit and Payment of Redemption Price.

          Prior to 10:00 a.m. (New York City time) on the Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) an amount of money sufficient to pay the Redemption
Price of, plus (except if the Redemption Date shall be an Interest Payment Date)

deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such





<PAGE>   73
                                      -65-



Security shall (subject to any right of the Holder of such Security or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 3.07) be paid to the Company upon Company Request or, if then held by
the Company, shall be discharged from such trust.

SECTION 11.08.   Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued and
unpaid interest, including Additional Payments, if any) such Securities shall
cease to bear interest.  Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued and unpaid interest (including
Additional Payments, if any) to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at 5:00 p.m. (New York City time) on
the relevant Record Dates according to the terms and provisions of Section 3.07.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal  shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security.

SECTION 11.09.   Securities Redeemed in Part.

          In the event of any redemption in part, the Company shall not be
required to (i) issue, register the transfer of or exchange any Security during
a period beginning at 9:00 a.m. (New York City time) 15 Business Days before any
selection for redemption of Securities and ending at 5:00 p.m. (New York City
time) on the earliest date in which the relevant notice of redemption is deemed
to have been given to all holders of Securities to be so redeemed and (ii)
register the transfer of or exchange any Securities so selected for redemption,
in whole or in part, except for the unredeemed portion of any Securities being
redeemed in part.

          Any Security which is to be redeemed only in part shall be surrendered
at a place of payment therefor (with, if 

<PAGE>   74
                                      -66-

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

SECTION 11.10.   No Sinking Fund.

          The Securities are not entitled to the benefit of any sinking fund.

                                 ARTICLE TWELVE

SECTION 12.01.   Agreement to Subordinate.

          The Company covenants and agrees, and each Holder of Securities by
such Holder's acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article Twelve; and
each Holder of a Security, whether upon original issue or upon transfer or
assignment thereof, accepts and agrees to be bound  by such provisions.  The
payment by the Company of the principal of, premium, if any, and interest
(including Additional Payments, if any) on all Securities issued hereunder
shall, to the extent and in the manner hereinafter set forth, be subordinated
and junior in right of payment to the prior payment in full of all existing and
future Senior Indebtedness, whether outstanding at the date of this Indenture or
thereafter incurred; provided however, that no provision of this Article Twelve
shall prevent the occurrence of any default or Event of Default hereunder.

SECTION 12.02.   Default on Senior Indebtedness.

          In the event and during the continuation of any default by the on any
Senior Indebtedness continuing beyond the period of grace, if any, specified in
the instrument evidencing such Senior Indebtedness, unless and until such
default shall have been cured or waived or shall have ceased to exist, and in
the event that the maturity of any 
<PAGE>   75

                                      -67-

Senior Indebtedness has been accelerated because of a default, then no payment
shall be made by the Company with respect to the principal of (including
redemption payments, if any), premium, if any, or interest on the Securities.

          In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 12.02, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any  of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 12.03.   Liquidation; Dissolution; Bankruptcy.

          Upon any distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding up or liquidation or reorganization of the Company,
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 must be paid in full before any payment
is made on account of the principal (and premium, if any) or interest (including
Additional Payments, if any) on the Securities; and upon any such dissolution or
winding up or liquidation or reorganization, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Securities or the Trustee
would be entitled, except for the provisions of this Article Twelve, shall be
paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the
Holders of the Securities or by the Trustee under this Indenture if received by
them or it, directly to the holders of Senior Indebtedness (pro rata to such
holders on the basis of the respective amounts of Senior Indebtedness held by
such holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any 
<PAGE>   76


                                      -68-

instruments evidencing such Senior Indebtedness may have been issued, as their
respective interests may appear, to the extent necessary to pay such Senior
Indebtedness in full, in money or money's worth, after giving effect to any
concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the Holders of
Securities or to the Trustee.

          In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or the Holders of the Securities before all Senior Indebtedness is paid
in full, or provision is made for such payment in money in accordance with its
terms, such payment or distribution shall be held in trust for the benefit of
and shall be paid over or delivered to the holders of Senior Indebtedness or
their representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, and their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay such Senior Indebtedness in full
in money in accordance with its terms, after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Indebtedness.

          For purposes of this Article Twelve, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Twelve with
respect to the Securities to the payment of all Senior Indebtedness which may at
the time be outstanding; provided, that (i) such Senior Indebtedness is assumed
by the new corporation, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of such Senior Indebtedness are
not, without the consent of such holders, altered by such reorganization or
readjustment.  The consolidation of the Company with, or the merger of the
Company with or into, another Person or the liquidation or dissolution of the
Company following the conveyance, transfer or lease of all or substantially all
its properties and assets on a consolidated basis to another Person upon the
terms and conditions provided for in Article Eight hereof shall not be deemed a
dissolution, winding up, liquidation or reorganization for the 

<PAGE>   77

                                      -69-

purposes of this Section 12.03 if such other Person shall, as a part of such
consolidation, merger, conveyance, transfer or lease, comply with the conditions
stated in Article Eight hereof.  Nothing in Section 12.02 or in this Section
12.03 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.07 hereof.

SECTION 12.04.   Subrogation.

          Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Securities shall be subrogated to the rights of the
holders of such Senior Indebtedness to receive payments or distributions of
cash, property or securities of the Company, as the case may be, applicable to
such Senior Indebtedness until the principal of (and premium, if any) and
interest (including Additional Payments, if any) on the Securities shall be paid
in full; and, for the purposes of such subrogation, no payments or distributions
to the holders of such Senior Indebtedness of any cash, property or securities
to which the Holders of the Securities or the Trustee would be entitled except
for the provisions of this Article Twelve, and no payment over pursuant to the
provisions of this Article Twelve, to or for the benefit of the holders of such
Senior Indebtedness by Holders of the Securities or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Indebtedness,
and the Holders of the Securities, be deemed to be a payment by the  Company to
or on account of such Senior Indebtedness.  It is understood that the provisions
of this Article Twelve are and are intended solely for the purposes of defining
the relative rights of the Holders of the Securities, on the one hand, and the
holders of such Senior Indebtedness on the other hand.

          Nothing contained in this Article Twelve or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness, and the
Holders of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest (including Additional Payments, if any) on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders of the Securities and creditors of the Company, as the case may be,
other than the holders of Senior Indebtedness, nor shall anything herein or
therein prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise 

<PAGE>   78
                                      -70-

permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article Twelve of the
holders of such Senior Indebtedness in respect of cash, property or securities
of the Company, as the case may be, received upon the exercise of any such
remedy.

          Upon any payment or distribution of assets of the Company referred to
in this Article Twelve, the Trustee, subject to the provisions of Section 6.03,
and the Holders of the Securities, shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which such dissolution,
winding up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders of the Securities, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, as the case may be, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Twelve.

SECTION 12.05.   Trustee to Effectuate Subordination.

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

SECTION 12.06.   Notice by the Company.

          The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company which would prohibit the making
of any payment of monies to or by the Trustee in respect of the Securities
pursuant to the provisions of this Article Twelve.  Notwithstanding the
provisions of this Article Twelve or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provision of this Article Twelve,
unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office of the Trustee from the
Company or a holder or holders of Senior Indebtedness or from any trustee
therefor; and before

<PAGE>   79
                                      -71-

the receipt of any such written notice, the Trustee, subject to the provisions
of Section 6.03 hereof, shall be entitled in all respects to assume that no such
facts exist; provided, however, that if the Trustee shall not have received the
notice provided for in this Section 12.06 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of (and
premium, if any) or interest (including Additional Payments, if any) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purposes for which they were received, and shall not be affected
by any notice to the contrary which may be received by it within two Business
Days prior to such date.

          The Trustee, subject to the provisions of Section 6.03, shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such notice has been given by a holder
of such Senior Indebtedness or a trustee on behalf of any such holder or
holders.  In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this  Article Twelve, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
right of such Person under this Article Twelve, and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

SECTION 12.07.   Rights of the Trustee; Holders of
                 Senior Indebtedness.             
                                                          

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

<PAGE>   80
                                      -72-

          With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are set forth in this Article Twelve, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be
read into this Indenture against the Trustee.  The Trustee shall not be deemed
to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Section 6.03, the Trustee shall not be liable to
any holder of such Senior Indebtedness if it shall pay over or deliver to
Holders of Securities, the Company or any other Person money or assets to which
any holder of such Senior Indebtedness shall be entitled by virtue of this
Article Twelve or otherwise.  With respect to the holders of Senior
Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants or obligations as are specifically set forth in this Article Twelve
and no implied covenants or obligations with respect to holders of Senior
Indebtedness shall be read into this Indenture against the Trustee.

SECTION 12.08.   Subordination May Not Be Impaired.

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

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

<PAGE>   81
                                      -73-

otherwise securing such Senior Indebtedness; (iii) release any Person liable in
any manner for the collection of such Senior Indebtedness; and (iv) exercise or
refrain from exercising any rights against the Company and any other Person.

                                ARTICLE THIRTEEN

                            Conversion of Securities

SECTION 13.01.   Conversion Rights.

          Subject to and upon compliance with the provisions of this Article,
the Securities are convertible, at the option of the Holder at any time after
[], 1997 and on or prior to 5:00 p.m. (New York City time) on the Business Day
immediately preceding the date of repayment of such Securities, whether at
maturity or upon redemption (either at the option of the Company or pursuant to
a Tax Event), into fully paid and nonassessable shares of Common Stock of the
Company at an initial conversion rate of [      ] shares of Common Stock for
each $25 in aggregate principal amount of Securities (equal to a conversion
price of $[      ] per share of Common Stock), subject to adjustment as
described in this Article Thirteen.  A Holder of Securities may convert any
portion of the principal amount of the Securities into that number of fully paid
and nonassessable shares of Common Stock (calculated as to each conversion to
the nearest 1/100th of a share) obtained by  dividing the principal amount of
the Securities to be converted by such conversion price. In case a Security or
portion thereof is called for redemption, such conversion right in respect of
the Security or portion so called shall expire at 5:00 p.m. (New York City time)
on the Business Day immediately preceding the corresponding Redemption Date,
unless the Company defaults in making the payment due upon redemption.

SECTION 13.02.   Conversion Procedures.

          (a)      In order to convert all or a portion of the Securities, the
Holder thereof shall deliver to the Conversion Agent an irrevocable Notice of
Conversion setting forth the principal amount of Securities to be converted,
together with the name or names, if other than the Holder, in which the shares
of Common Stock should be issued upon conversion and, if such Securities are
definitive Securities, surrender to the Conversion Agent the Securities to be
converted, duly endorsed or assigned to the Company or in blank.  In addition, a
holder of Preferred Securities may exercise its right under the 

<PAGE>   82


                                      -74-

     Declaration to convert such Preferred Securities into Common Stock by
     delivering to the Conversion Agent an irrevocable Notice of Conversion
     setting forth the information called for by the preceding sentence and
     directing the Conversion Agent (i) to exchange such Preferred Security for
     a portion of the Securities held by the Trust (at an exchange rate of $25
     principal amount of Securities for each Preferred Security) and (ii) to
     immediately convert such Securities, on behalf of such holder, into Common
     Stock of the Company pursuant to this Article Thirteen and, if such
     Preferred Securities are in definitive form, surrendering such Preferred
     Securities, duly endorsed or assigned to the Company or in blank.  So long
     as any Preferred Securities are outstanding, the Trust shall not convert
     any Securities except pursuant to a Notice of Conversion delivered to the
     Conversion Agent by a holder of Preferred Securities.

          If a Notice of Conversion is delivered on or after the Regular Record
     Date and prior to the subsequent Interest Payment Date, the Holder shall be
     required to pay to the Company the interest payable on the subsequent
     Interest Payment Date, and will be entitled to receive the interest payable
     on the subsequent Interest Payment Date, on the portion of Securities to be
     converted notwithstanding the conversion thereof prior to such Interest
     Payment Date.  Notwithstanding the foregoing, if, during an Extension
     Period, a notice of redemption is mailed pursuant to Section 11.06 and a
     Security  is converted after such mailing but prior to the relevant
     Redemption Date, all accrued but unpaid interest (including Additional
     Payments, if any) through the date of conversion shall be paid to the
     holder of such Security on the Redemption Date. Except as otherwise
     provided in the immediately preceding two sentences, in the case of any
     Security which is converted, interest whose Stated Maturity is after the
     date of conversion of such Security shall not be payable, and the Company
     shall not make nor be required to make any other payment, adjustment or
     allowance with respect to accrued but unpaid interest (including Additional
     Payments, if any) on the Securities being converted, which shall be deemed
     to be paid in full.  If any Security called for redemption is converted,
     any money deposited with the Trustee or with any Paying Agent or so
     segregated and held in trust for the redemption of such Security shall
     (subject to any right of the Holder of such Security or any Predecessor
     Security to receive interest as provided in the last paragraph of Section
     3.07 and this paragraph) be paid to the Company upon Company Request or, if
     then held by the Company, shall be discharged from such trust.


<PAGE>   83

                                      -75-


          Each conversion shall be deemed to have been effected immediately
     prior to 5:00 p.m. (New York City time) on the day on which the Notice of
     Conversion was received (the "Conversion Date") by the Conversion Agent
     from the Holder or from a holder of the Preferred Securities effecting a
     conversion thereof pursuant to its conversion rights under the Declaration,
     as the case may be.  The Person or Persons entitled to receive the Common
     Stock issuable upon such conversion shall be treated for all purposes as
     the record holder or holders of such Common Stock as of the Conversion
     Date.  As promptly as practicable on or after the Conversion Date, the
     Company shall issue and deliver at the office of the Conversion Agent,
     unless otherwise directed by the Holder in the Notice of Conversion, a
     certificate or certificates for the number of full shares of Common Stock
     issuable upon such conversion, together with the cash payment, if any, in
     lieu of any fraction of any share to the Person or Persons entitled to
     receive the same.  The Conversion Agent shall deliver such certificate or
     certificates to such Person or Persons.

          (b)      Subject to any right of the Holder of such Security or any
     Predecessor Security to receive interest as provided in the last paragraph
     of Section 3.07 and the second paragraph of Clause (a) of Section 13.02,
     the Company's delivery upon conversion of the fixed number of shares of
     Common Stock into which the Securities are convertible  (together with the
     cash payment, if any, in lieu of fractional shares) shall be deemed to
     satisfy the Company's obligation to pay the principal amount of the portion
     of Securities so converted and any unpaid interest (including Additional
     Payments, if any) accrued on such Securities at the time of such
     conversion.

          (c)      No fractional shares of Common Stock will be issued as a
     result of conversion, but in lieu thereof, the Company shall pay to the
     Conversion Agent a cash adjustment in an amount equal to the same fraction
     of the last reported sale price of such fractional interest on the date on
     which the Securities or Preferred Securities, as the case may be, were duly
     surrendered to the Conversion Agent for conversion, or, if such day is not
     a Trading Day, on the next Trading Day, and the Conversion Agent in turn
     will make such payment, if any, to the Holder of the Securities or the
     holder of the Preferred Securities so converted.

          (d)      In the event of the conversion of any Security in part only,
     a new Security or Securities for the unconverted portion thereof will be
     issued in the name of the Holder 

<PAGE>   84

                                      -76-


thereof upon the cancellation thereof in accordance with Section 3.05.

          (e)      In effecting the conversion transactions described in this
Section, the Conversion Agent is acting as agent of the holders of Preferred
Securities (in the exchange of Preferred Securities for Securities) and as agent
of the Holders of Securities (in the conversion of Securities into Common
Stock), as the case may be, directing it to effect such conversion transactions.
The Conversion Agent is hereby authorized (i) to exchange Securities held by the
Trust from time to time for Preferred Securities in connection with the
conversion of such Preferred Securities in accordance with this Article Thirteen
and (ii) to convert all or a portion of the Securities into Common Stock and
thereupon to deliver such shares of Common Stock in accordance with the
provisions of this Article Thirteen and to deliver to the Trust a new Security
or Securities for any resulting unconverted principal amount.

SECTION 13.03.   Conversion Price Adjustments.

          The conversion price shall be subject to adjustment (without
duplication) from time to time as follows:

          (a)      In case the Company shall, while any of the Securities are
     outstanding, (i) pay a dividend or make a distribution with respect to its
     Common Stock in shares of Common Stock, (ii) subdivide its outstanding
     shares of Common Stock, (iii) combine its outstanding shares of Common
     Stock into a smaller number of shares or (iv) issue by reclassification of
     its shares of Common Stock any shares of capital stock of the Company, the
     conversion price in effect immediately prior to such action shall be
     adjusted so that the Holder of any Securities thereafter surrendered for
     conversion shall be entitled to receive the number of shares of capital
     stock of the Company which he would have owned immediately following such
     action had such Securities been converted immediately prior thereto.  An
     adjustment made pursuant to this Section 13.03(a) shall become effective
     immediately after the record date in the case of a dividend or other
     distribution and shall become effective immediately after the effective
     date in case of a subdivision, combination or reclassification (or
     immediately after the record date if a record date shall have been
     established for such event).  If, as a result of an adjustment made
     pursuant to this Section 13.03(a), the Holder of any Security thereafter
     surrendered for 

<PAGE>   85
                                      -77-


     conversion shall become entitled to receive shares of two or more classes
     or series of capital stock of the Company, the Board of Directors (whose
     determination shall be conclusive and shall be described in a Board
     Resolution filed with the Trustee) shall determine the allocation of the
     adjusted conversion price between or among shares of such classes or series
     of capital stock.
        
          (b)      In case the Company shall, while any of the Securities are
     outstanding, issue rights or warrants to all holders of its Common Stock
     entitling them (for a period expiring within 45 days after the record date
     mentioned in this Section 13.03(b)) to subscribe for or purchase shares of
     Common Stock at a price per share less than the Current Market Price per
     share of Common Stock (as determined pursuant to 13.03(f) below) on such
     record date, the conversion price for the Securities shall be adjusted so
     that the same shall equal the price determined by multiplying the
     conversion price in effect immediately prior to the date of issuance of
     such rights or warrants by a fraction of which the numerator shall be the
     number of shares of Common Stock outstanding on the date of issuance of
     such rights or warrants plus the number of shares which the aggregate
     offering price of the total  number of shares so offered for subscription
     or purchase would purchase at such Current Market Price, and of which the
     denominator shall be the number of shares of Common Stock outstanding on
     the date of issuance of such rights or warrants plus the number of
     additional shares of Common Stock offered for subscription or purchase.
     Such adjustment shall become effective immediately after the record date
     for the determination of stockholders entitled to receive such rights or
     warrants.  For the purposes of this subsection, the number of shares of
     Common Stock at any time outstanding shall not include shares held in the
     treasury of the Company.  The Company shall not issue any rights or
     warrants in respect of shares of Common Stock held in the treasury of the
     Company.  In case any rights or warrants referred to in this subsection in
     respect of which an adjustment shall have been made shall expire
     unexercised within 45 days after the same shall have been distributed or
     issued by the Company, the conversion price shall be readjusted at the time
     of such expiration to the conversion price that would have been in effect
     if no adjustment had been made on account of the distribution or issuance
     of such expired rights or warrants.

<PAGE>   86
                                      -78-

 
                 (c)      Subject to the last sentence of this Section
         13.03(c), in case the Company shall, by dividend or otherwise,
         distribute to holders of its Common Stock evidences of its
         indebtedness, shares of any class or series of capital stock, cash or
         assets (including securities, but excluding any rights or warrants
         referred to in Section 13.03(b), any dividend or distribution paid
         exclusively in cash and any dividend or distribution referred to in
         Section 13.03(a)), the conversion price shall be reduced so that the
         same shall equal the price determined by multiplying the conversion
         price in effect immediately prior to the effectiveness of the
         conversion price reduction contemplated by Section 13.03(c) by a
         fraction of which the numerator shall be the Current Market Price per
         share (determined as provided in Section 13.03(f)) of the Common Stock
         on the date fixed for the payment of such distribution (the "Reference
         Date") less the fair market value (as determined in good faith by the
         Board of Directors, whose determination shall be conclusive and
         described in a resolution of the Board of Directors), on the Reference
         Date, of the portion of the evidences of indebtedness, shares of
         capital stock, cash and assets so distributed applicable to one share
         of Common Stock and the denominator shall be such Current  Market
         Price per share of the Common Stock, such reduction to become
         effective immediately prior to the opening of business on the day
         following the Reference Date.  In the event that such dividend or
         distribution is not so paid or made, the conversion price shall again
         be adjusted to be the conversion price which would then be in effect
         if such dividend or distribution had not occurred.  If the Board of
         Directors determines the fair market value of any distribution for
         purposes of this Section 13.03(c) by reference to the actual or when
         issued trading market for any securities comprising such distribution,
         it must in doing so consider the prices in such market over the same
         period used in computing the Current Market Price per share of Common
         Stock (determined as provided in Section 13.03(f)).  For purposes of
         this Section 13.03(c), any dividend or distribution that includes
         shares of Common Stock or rights or warrants to subscribe for or
         purchase shares of Common Stock shall be deemed instead to be (1) a
         dividend or distribution of the evidences of indebtedness, shares of
         capital stock, cash or assets other than such shares of Common Stock
         or such rights or warrants (making any conversion price reduction
         required by this Section 13.03(c)) immediately followed by (2) a
         dividend or distribution of such shares of Common Stock or such rights
         or 
<PAGE>   87
                                      -79-


     warrants (making any further conversion price reduction required by Section
     13.03(a) or 13.03(b)), except (A) the Reference Date of such dividend or
     distribution as defined in this 13.03(c) shall be substituted as (a) "the
     record date in the case of a dividend or other distribution," and (b) "the
     record date for the determination of stockholders entitled to receive such
     rights or warrants" and (c) "the date fixed for such determination" within
     the meaning of Sections 13.03(a) and 13.03(b) and (B) any shares of Common
     Stock included in such dividend or distribution shall not be deemed
     outstanding for purposes of computing any adjustment of the conversion
     price in Section 13.03(a).

          (d)      In case the Company shall pay or make a dividend or other
     distribution on its Common Stock exclusively in cash (excluding any cash
     distribution referred to in 13.03(c)) 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 Section 13.03(c)) 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 12 months preceding such distribution, exceeds 12.5%
     of the Company's market capitalization (being the product of the Current
     Market Price multiplied by the number of shares of Common Stock then
     outstanding (Current Market Price per share shall be determined as provided
     in Section 13.03(f) of the Common Stock on the Trading Day immediately
     preceding the date of declaration of such dividend)), the conversion price
     shall be reduced so that the same shall equal the price determined by
     multiplying the conversion price in effect immediately prior to the
     effectiveness of the conversion price reduction contemplated by this
     Section 13.03(d) by a fraction of which the numerator shall be the Current
     Market Price per share (determined as provided in Section 13.03(f)) of the
     Common Stock on the date fixed for the payment of such distribution less
     the amount of cash so distributed and not excluded as provided applicable
     to one share of Common Stock and the denominator shall be such Current
     Market Price per share of the Common Stock, such reduction to become
     effective immediately prior to the opening of business on the day following
     the date fixed for the payment of such distribution; provided, however,
     that in the event the portion of the cash so distributed applicable to one
     share of Common Stock is equal 

<PAGE>   88

                                      -80-

     to or greater than the Current Market Price per share (as defined in
     Section 13.03(f)) of the Common Stock on the record date mentioned above,
     in lieu of the foregoing adjustment, adequate provision shall be made so
     that each Holder of shares of Securities shall have the right to receive
     upon conversion the amount of cash such Holder would have received had such
     Holder converted each share of the Securities immediately prior to the
     record date for the distribution of the cash.  In the event that such
     dividend or distribution is not so paid or made, the conversion price shall
     again be adjusted to be the conversion price which would then be in effect
     if such record date had not been fixed.

          (e)      In the case of a tender offer by the Company or any
     Subsidiary of the Company for 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 Section 13.03(c)) 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 (being the
     product of the Current Market Price multiplied by the number of shares of
     Common Stock then outstanding (Current Market Price per share shall be
     determined as provided in 13.03(f)) at the date of consummation of such
     tender offer, the conversion price shall be reduced so that the same shall
     equal the price determined by multiplying the conversion price in effect
     immediately prior to the effectiveness of the conversion price reduction
     contemplated by this Section 13.03(e) by a fraction of which the numerator
     shall be the number of shares of Common Stock outstanding (including any
     tendered shares) multiplied by the closing bid price per share of the
     Common Stock on the Trading Day next succeeding the last time tenders may
     be made pursuant to such tender offer (as it shall have been amended) (the
     "Expiration Time") and the denominator shall be the sum of (x) the fair
     market value (determined as aforesaid) of the aggregate consideration
     payable to stockholders based on the acceptance (up to any maximum
     specified in the terms of the tender offer) of all shares validly tendered
     and not withdrawn as of the Expiration Time (the shares deemed so accepted,
     up to any such

<PAGE>   89
                                      -81-


          maximum, being referred to as the "Purchased Shares") and (y) the
          product of the number of shares of Common Stock outstanding (less any
          Purchased Shares) at the Expiration Time and the closing bid price per
          share of the Common Stock on the Trading Day next succeeding the
          Expiration Time, such reduction to become effective immediately prior
          to the opening of business on the day following the Expiration Time.

               (f)      For the purpose of any computation under Section
          13.03(b), 13.03(c), 13.03(d) or 13.03(e), the "Current Market Price"
          per share of Common Stock or any other security on any date in
          question shall be deemed to be 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; provided, however, that if another event
          occurs that would require an adjustment pursuant to Section 13.03(a)
          through (e), inclusive, the Board of Directors may make such
          adjustments to the Closing Prices during such ten Trading Day period
          as it deems appropriate to effectuate the  intent of the adjustments
          in this Section 13.03, in which case any such determination by the
          Board of Directors shall be set forth in a Board Resolution and shall
          be conclusive.

               (g)      The Company may make at its option such reductions in
          the conversion price, in addition to those required by Sections 13.03
          (a) through (e), as it considers to be advisable to avoid or diminish
          any income tax to holders of Common Stock or rights to purchase 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.  The Company from time to time may reduce the conversion
          price by any amount for any period of time if the period is at least
          20 days, the reduction is irrevocable during the period, and the Board
          of Directors of the Company shall have made a determination that such
          reduction would be in the best interest of the Company, which
          determination shall be conclusive.  Whenever the conversion price is
          reduced pursuant to the preceding sentence, the Company shall mail to
          holders of record of the Securities a notice of the reduction at least
          15 days prior to the date the reduced conversion price takes effect,
          and such notice shall state the reduced conversion price and the
          period it will be in effect.

                                      -82-


               (h)      No adjustment in the conversion price shall be required
          unless such adjustment would require an increase or decrease of at
          least 1% in the conversion price then in effect; provided, however,
          that any adjustments which by reason of this Section 13.03(h) are not
          required to be made shall be carried forward and taken into account in
          determining whether any subsequent adjustment shall be required.

               (i)      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 Securities.

SECTION 13.04.   Reclassification, Consolidation, Merger
                 or Sale of Assets.                     

               (a)      In the event that the Company shall be a party to any
transaction or series of transactions constituting a Fundamental Change (as
hereinafter defined), 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 of the Company with, or merger of the Company into, any other
Person, any merger of another Person into the Company (other than a merger
which does not result in a reclassification, conversion, exchange or
cancellation of outstanding shares of 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 as part of the terms of such transaction or
series of transactions so that the holders of each Security then outstanding
shall have the right thereafter to convert such Security only into (A) if any
such transaction does not constitute a Common Stock Fundamental Change (as
hereinafter defined), 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 into which such Security might
have been converted immediately prior to such recapitalization,
reclassification, consolidation, merger, sale, transfer or share exchange,
after, in the case of a Non-Stock Fundamental Change (as hereinafter 

<PAGE>   91
                                      -83-


defined), giving effect to any adjustment in the conversion price required by
the provisions which follow in subparagraph (i) of Section 13.04(c), and (B) in
the case of a Common Stock Fundamental Change (as hereinafter defined), common
stock of the kind received by holders of Common Stock as a result of such Common
Stock Fundamental Change in an amount determined pursuant to the provisions
which follow in subparagraph (ii) of Section 13.04(c).  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 Trustee, satisfactory in form to the Trustee and
executed and delivered to the Trustee, the provisions of which shall establish
such right and provide for adjustments which, for events subsequent to the
effective date of such supplemental indenture, shall be  as nearly equivalent as
may be practicable to the adjustments provided for in this Article Thirteen.
The above provisions shall similarly apply to successive recapitalizations,
reclassifications, consolidations, mergers, sales, transfers or share exchanges.

               (b)      Notwithstanding any other provisions in this Article
Thirteen to the contrary, if any Fundamental Change occurs, then the conversion
price in effect will be adjusted immediately following such Fundamental Change
as described below in Section 13.04(c).  In addition, in the event of a Common
Stock Fundamental Change, each Security shall be convertible solely into common
stock of the kind received by holders of Common Stock as the result of such
Common Stock Fundamental Change as more specifically provided below in Section
13.04(c).

               (c)      For purposes of calculating any adjustment to be made
pursuant to this Article Thirteen in the event of a Fundamental Change,
immediately following such Fundamental Change (and for such purposes a
Fundamental Change shall be deemed to occur on the earlier of (a) the occurrence
of such Fundamental Change and (b) the date, if any, fixed for determination of
shareholders entitled to receive the cash, securities, property or other assets
distributable in such Fundamental Change to holders of the Common Stock):

               (i)    in the case of a Non-Stock Fundamental Change, the
          conversion price per share of Common Stock shall 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 this Article Thirteen, and (B) the

<PAGE>   92
                                      -84-


         product of (1) the greater of the Applicable Price (as hereinafter
         defined) and the then applicable Reference Market Price (as
         hereinafter defined) and (2) a fraction the numerator of which shall
         be $25 and the denominator of which shall be (x) the amount set forth
         below (based on the date on which such Non-Stock Fundamental Change
         occurs).  For the twelve month period beginning on [        ] in the
         year indicated:

         Year                                                     Denominator

         Payments, if any) on $25 principal amount of Securities; and

               (ii)    in the case of a Common Stock Fundamental Change, the
          conversion price per share of Common Stock shall be the conversion
          price in effect immediately prior to such Common Stock Fundamental
          Change, but after giving effect to any other adjustments effected
          pursuant to this Article Thirteen, multiplied by a fraction, the
          numerator of which is the Purchaser Stock Price (as hereinafter
          defined) 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
          such shares of common stock resulting from such Common Stock
          Fundamental Change) and (B) all of the Common Stock 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 such Common Stock Fundamental
     Change shall be the conversion price in effect immediately prior to such
     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 such Common Stock Fundamental
     Change.

          (d)      The following definitions shall apply to terms used in this
     Article Thirteen:

          (i)    "Applicable Price" means (A) 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
     (B) 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.

          (ii)    "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 Nasdaq National
     Market; provided, however, that a Fundamental Change will not be a Common
     Stock Fundamental Change unless either (A) 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 (B) the outstanding Preferred Securities continue to exist as Preferred
     Securities and are convertible into shares of common stock of the successor
     to the Company.

          (iii)    "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

<PAGE>   94

                                      -86-

     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 received 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.

          (iv)    "Non-Stock Fundamental Change" means any Fundamental Change
     other than a Common Stock Fundamental Change.

          (v)    "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 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.

          (vi)    "Reference Market Price" will initially mean $[ ] (which,
     unless otherwise specified in this Indenture, will be 66 2/3% of the last
     reported sale price per share of Common Stock on the Nasdaq National Market
     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.

          (e)      In determining the amount and type of consideration received
by a holder of Common Stock in the event of a 

<PAGE>   95


                                      -87-

Fundamental Change, consideration received by a holder of Common Stock pursuant
to a statutory right of appraisal will be disregarded.

SECTION 13.05.   Notice of Adjustments of Conversion Price.

          Whenever the conversion price is adjusted as herein provided:

          (a)      the Company shall compute the adjusted conversion price and

     showing in reasonable detail the facts upon which such adjustment is based,
     and such certificate shall forthwith be filed with the Trustee, the
     Conversion Agent and the transfer agent for the Preferred Securities and
     the Securities; and

          (b)      a notice stating the conversion price has been adjusted and
     setting forth the adjusted conversion price shall as soon as practicable be
     mailed by the Company to all record holders of Preferred Securities and the
     Securities at their last addresses as they appear upon the stock transfer
     books of the Company and the Trust.

SECTION 13.06.   Prior Notice of Certain Events.

          In case:

          (a)      the Company shall (i) declare any dividend (or any other
     distribution) on its Common Stock, other than (A) a dividend payable in
     shares of Common Stock or (B) a dividend payable in cash that would not
     require an adjustment pursuant to Section 13.03(c) or 13.03(d), or (ii)
     authorize a tender or exchange offer that would require an adjustment
     pursuant to Section 13.03(e);

          (b)      the Company shall authorize the granting to all holders of
     Common Stock of rights or warrants to subscribe for or purchase any shares

     par value, or from par value to no par value, or from no par value to par
     value), or of any consolidation or merger to which the Company is a

     party and for which approval of any stockholders of the Company shall be
     required, or of the sale or transfer of all or substantially all of the
     assets of the Company or of any compulsory share exchange whereby the
     Common Stock is converted into other securities, cash or other property; or

          (d)      of the voluntary or involuntary dissolution, liquidation or

date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, share exchange, dissolution, liquidation or winding up (but no failure
to mail such notice or any defect therein or in the mailing thereof shall affect
the validity of the corporate action required to be specified in such notice).

SECTION 13.07.   Certain Defined Terms.

          The following definitions shall apply to terms used in this Article
Thirteen:

          (a)      "Closing Price" of any Common Stock or other Security on any
     day shall mean the last reported sale price regular way on such day or, in
     case no such sale takes place on such day, the average of the reported
     closing bid and asked prices regular way of such Common Stock, in each case
     on the Nasdaq National Market or, if the 

<PAGE>   97

                                      -89-


     Common Stock is not listed or admitted to trading on such exchange, on the
     principal national securities exchange on which such common stock is listed
     or admitted to trading, or, if not listed or admitted to trading on any
     national securities exchange, the average of the closing bid and asked
     prices as furnished by any Nasdaq National Market member firm selected from
     time to time by the Board of Directors of the Company for that purpose or,
     if not so available in such manner, as otherwise determined in good faith
     by the Board of Directors.

          (b)      "Trading Day" shall mean a day on which securities are traded
     on the national securities exchange or quotation system used to determine
     the Closing Price.

SECTION 13.08.   Dividend or Interest Reinvestment Plans.

of Common Stock pursuant to any 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, and
the issuance of any shares of Common Stock or options or rights to purchase such
shares pursuant to any employee benefit plan or program of the Company or
pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security outstanding as of the date the Securities were first
issued, shall not be deemed to constitute an issuance of Common Stock or
exercisable, exchangeable or convertible securities by the Company to which any
of the adjustment provisions described above applies.  There shall also be no
adjustment of the conversion price in case of the issuance of any stock (or
securities convertible into or exchangeable for stock) of the Company except as
specifically described in this Article Thirteen.

SECTION 13.09.   Certain Additional Rights.

          In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in Section 13.03(c) or 13.03(d)
(including, without limitation, dividends or distributions referred to in the
last sentence of Section 13.03(c)), the Holder of the Securities, upon the
conversion thereof subsequent to 5:00 p.m. (New York City time) on the date
fixed for the determination of stockholders entitled to receive such
distribution and prior to the effectiveness of the conversion price adjustment
in respect of such distribution, shall also be entitled to receive for each
share of

<PAGE>   98
                                      -90-


Common Stock into which the Securities are converted, the portion of the shares

portion of such distribution not consisting of cash or securities of the
Company, pay such Holder an amount in cash equal to the  fair market value
thereof (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors).  If any conversion of Securities described in the immediately
preceding sentence occurs prior to the payment date for a distribution to
holders of Common Stock which the Holder of Securities so converted is entitled
to receive in accordance with the immediately preceding sentence, the Company
may elect (such election to be evidenced by a resolution of the Board of
Directors) to distribute to such Holder a due bill for the shares of Common
Stock, rights, warrants, evidences of indebtedness, shares of capital stock,
cash or assets to which such Holder is so entitled, provided, that such due bill
(i) meets any applicable requirements of the principal national securities
exchange or other market on which the Common Stock is then traded and (ii)
requires payment or delivery of such shares of Common Stock, rights, warrants,
evidences of indebtedness, shares of capital stock, cash or assets no later than
the date of payment or delivery thereof to holders of shares of Common Stock

                         [FORM OF REVERSE OF SECURITY]

          This Security is one of a duly authorized issue of securities of the
Company designated as its [  ]% Convertible Subordinated Debenture Due 2017
(herein called the "Securities"), in aggregate principal amount of $[ ] (or up
to $[          ] if the over- allotment option is exercised by the Trust in
accordance with the terms and provisions of the Underwriting Agreement), issued
and to be issued under an Indenture, dated as of [ ], 1997 (herein called the
"Indenture"), between the Company and [ ], as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,
authenticated and delivered.  The terms of the Securities include those stated
in the Indenture and those made part of the Indenture by the Trust Indenture Act
of 1939 (15 U.S.C. Section Section 77aaa-77bbbb) ("TIA") as in effect on the
date of the Indenture.  The Securities are subject to, and qualified by, all
such terms, certain of which are summarized hereon, and holders are referred to
the Indenture and the TIA for a statement of such terms.  No reference herein to
the Indenture and no provision of this Security or of the Indenture shall alter
or impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of and interest on this Security at the times, place and rate,
and in the coin or currency, herein prescribed or to convert this Security as
provided in the Indenture.  All terms used in this Security which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.  The
Company will furnish to any Holder upon written request and without charge a
copy of the Indenture.

          (1)      Interest.  The Securities shall bear interest at the rate of
[  ]% per annum, from [        ], 1997 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, as the case may be,
payable quarterly (subject to deferral as set forth herein), in arrears, on
March 31, June 30, September 30 and December 31 (each an "Interest Payment
Date") of each year, commencing March 31, 1997, until the principal thereof is
paid or made available for payment, and they shall be paid to the Person in
whose name the Security is registered at 5:00 p.m. (New York  City time) on the
regular record date for such interest installment, which shall

                                     A-4
<PAGE>   106
                                      -5-

be the March 15, June 15, September 15 and December 15 next preceding such
Interest Payment Date (the "Regular Record Date").  Interest will compound
quarterly and will accrue at the rate of [  ]% per annum on any interest
installment in arrears for more than one quarter or during an extension of an
interest payment period as set forth below.

          The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  Except as provided in the
following sentence, 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 per 90-day quarter.  In the event
that any date on which interest is payable on the Securities is not a Business
Day, then payment of interest 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 shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

          If at any time while the Institutional Trustee is the Holder of any
Securities, the Trust or the Institutional Trustee is required to pay any taxes,
duties, assessments or governmental charges of whatever nature (other than
withholding taxes) imposed by the United States, or any other taxing authority,
then, in any such case, the Company shall pay as additional interest
("Additional Interest") on the Securities held by the Institutional Trustee,
such amounts as shall be required so that the net amounts received and retained
by the Trust and the Institutional Trustee after paying any such taxes, duties,
assessments or other governmental charges will be not less than the amounts the
Trust and the Institutional Trustee would have received had no such taxes,
duties, assessments or other governmental charges been imposed.

          The principal of and interest on the Securities shall be payable at
the office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
check mailed to the address 


                                     A-5
<PAGE>   107

                                      -6-

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



          (2)      Option to Extend Interest Payment Period.  The Company shall
have the right at any time during the term of the Securities to defer interest
payments (including Additional Payments) by extending the interest payment
period for a period (each, an "Extension Period") not exceeding 20 consecutive
quarters; provided, no Extension Period may extend beyond the maturity date of
the Securities and at the end of which Extension Period, the Company shall pay
all interest then accrued and unpaid (including Additional Interest) together
with interest thereon compounded quarterly at the rate specified for the
Securities to the extent permitted by applicable law ("Compounded Interest");
provided, that during any Extension Period, the Company shall (i) not declare or
pay dividends on, or make any distributions with respect to, or redeem or
purchase or acquire, or liquidation payments with respect to, or redeem,
purchase or acquire any of its capital stock (other than (A) 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, (B) 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 (C) 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 (D) stock dividends paid by the Company where the dividend stock
is the same as that on which the dividend is paid), (ii) 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 that
rank pari passu with or junior to the Securities and (iii) 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 such 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 Securities.  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 during 
                                     A-6


<PAGE>   108

                                      -7-

an Extension Period shall be due and payable. Notwithstanding anything to the
contrary, the Company shall not have the right at any time to defer any
Additional Interest, including by extending the interest payment period.

          If the Institutional Trustee is the sole Holder of the Securities at
the time the Company selects an Extension Period, the Company shall give written
notice to the Regular Trustees, the Institutional Trustee and the Trustee 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) if the Preferred Securities
are listed on the Nasdaq National Market or any other stock exchange or
quotation system, the date the Regular Trustees are required to give notice to
the Nasdaq National Market (or other applicable self-regulatory organization) or
to holders of the Preferred Securities of the record date or the date such
distributions would be payable if not for such Extension Period, but in any
event not less than one Business Day prior to such record date.

          If the Institutional Trustee is not the sole Holder of the Securities
at the time the Company selects an Extension Period, the Company shall give the
Holders of the Securities and the Trustee written notice of its selection of
such Extension Period at least 10 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 Nasdaq National Market (or any applicable
self-regulatory organization) or to Holders of the Securities on the record or
payment date of such related interest payment.

          The quarter in which any notice is given pursuant to paragraphs second
and third of this Section 2 shall be counted as one of the 20 quarters permitted
in the maximum Extension Period permitted under paragraph one of this Section 2.

          (3)      Paying Agent and Security Registrar.  The Trustee will act as
Paying Agent, Security Registrar and Conversion Agent.  The Company may change
any Paying Agent, Security Registrar, co-registrar or Conversion Agent without
prior notice.  The Company or any of its Affiliates may act in any such
capacity.

          (4)      Redemption.  The Securities are redeemable, in whole or in
part, at any time or from time to time after  [          ], 2000 at the
redemption prices (expressed as a

percentage of the principal amount of Securities) specified below for the 12
month period commencing [          ] in the year indicated ([          ], in the
case of 2000), if redeemed during the 12-month period beginning December 31:

      2000                                                        %

      2007 and thereafter                                     100 .0%

plus, in each case, accrued and unpaid interest (including Additional Payments,
if any) to the Redemption Date.  On and after the Redemption Date, interest
ceases to accrue on the Securities or portions of them called for redemption.

          The Securities are subject to redemption in whole or in part), at any
time within 90 days, under certain circumstances if a Tax Event (as defined in
the Declaration) shall occur and be continuing, at a redemption price equal to
100% of the principal amount thereof plus accrued but unpaid interest (including
Additional Payments, if any) to the Redemption Date.  On and after the
Redemption Date, interest ceases to accrue on the Securities or portions of them
called for redemption.

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at such Holder's address
appearing in the Security Register.  The Securities in denominations larger than
$25 may be redeemed in part but only in integral multiples of $25. In the event
of a redemption of less than all of the Securities, the Securities will be
chosen for redemption by the Trustee in accordance with the Indenture.

          If this Security is redeemed subsequent to a Regular Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the person in
whose name this 


                                     A-8

                                      -9-

Security is registered at the close of business on such record date.

          (5)      Sinking Fund.  The Securities are not entitled to the benefit
of any sinking fund.


          (6)      Subordination.  The payment of the principal of, premium, if
any, and interest (including Additional Payments, if any) on all Securities is
subordinated and junior in right of payment to the prior payment in full of all
existing and future Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred.  Each holder, by accepting a Security, agrees
to such subordination and authorizes and directs the Trustee on its behalf to
take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee as its attorney-in-fact for
such purpose.

          (7)      Conversion.  The Holder of any Security has the right,
exercisable at any time after [           ], 1997 and on or before 5:00 p.m.
(New York City time) on the Business Day immediately preceding the date of
repayment of such Securities, whether at maturity or upon redemption (either at
the option of the Company or pursuant to a Tax Event), to convert the principal
amount thereof (or any portion thereof that is an integral multiple of $25) into
fully paid and nonassessable shares of Common Stock of the Company at an initial
conversion rate of [     ] shares of Common Stock for each $25 in aggregate
principal amount of Securities (equal to a conversion price of $[ ] per share of
Common Stock), subject to adjustment under certain circumstances.  The number of
shares issuable upon conversion of a Security is determined by dividing the
principal amount of the Security converted by the conversion price in effect on
the Conversion Date.  No fractional shares will be issued upon conversion but a
cash adjustment will be made for any fractional interest.  The outstanding
principal amount of any Security shall be reduced by the portion of the
principal amount thereof converted into shares of Common Stock.

          To convert a Security, a Holder must (i) complete and sign a
conversion notice substantially in the form attached hereto, (ii) surrender the
Security to a Conversion Agent, (iii) furnish appropriate endorsements or
transfer documents if required by the Security Registrar or Conversion Agent and
(iv) pay any transfer or similar tax, if required.  If a Notice of Conversion is
delivered on or after the Regular Record Date and prior to the subsequent
Interest Payment Date, the Holder shall 


                                     A-9
<PAGE>   111


                                     -10-

be required to pay to the Company the interest payment on the  subsequent
Interest Payment Date and, will be entitled to receive the interest payable on
the subsequent Interest Payment Date, on the portion of Securities to be
converted notwithstanding the conversion thereof prior to such Interest Payment
Date.  Notwithstanding the foregoing, if, during an Extension Period, a notice
of redemption is mailed pursuant to Section 11.06 of the Indenture and a
Security is converted after such mailing but prior to the relevant Redemption
Date, all accrued but unpaid interest (including Additional Payments, if any)
through the date of conversion shall be paid to the holder of such Security on
the Redemption Date.  Except as otherwise provided in the immediately preceding
two sentences, in the case of any Security which is converted, interest whose
Stated Maturity is after the date of conversion of such Security shall not be
payable, and the Company shall not make nor be required to make any other
payment, adjustment or allowance with respect to accrued but unpaid interest
(including Additional Payments, if any) on the Securities being converted, which
shall be deemed to be paid in full.  If any Security called for redemption is
converted, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Security shall (subject
to any right of the Holder of such Security or any Predecessor Security to
receive interest as provided in the last paragraph of Section 3.07 of the
Indenture and this paragraph) be paid to the Company upon Company Request or, if
then held by the Company, shall be discharged from such trust.

          (8)      Registration, Transfer, Exchange and Denominations. As
provided in the Indenture and subject to certain limitations therein set forth,
the transfer of this Security is registrable in the Security Register, upon
surrender of this Security for registration of transfer at the office or agency
of the Company, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities are issuable only in registered form without coupons in
denominations of $25 and integral multiples thereof.  No service charge shall be
made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.  Prior to due presentment of 



                                     A-10
<PAGE>   112
                                      11

this Security for registration of transfer,  the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not
this Security be overdue, and neither the Company, the Trustee nor any such
agent shall be affected by notice to the contrary.  In the event of redemption
or conversion of this Security in part only, a new Security or Securities for
the unredeemed or unconverted portion hereof will be issued in the name of 
the Holder hereof upon the cancellation hereof.

          (9)      Persons Deemed Owners.  Except as provided in the Indenture,
the registered Holder of a Security may be treated as its owner for all
purposes.

          (10)     Unclaimed Money.  If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent shall
pay the money back to the Company at its written request. After that, holders of
Securities entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

          (11)     Defaults and Remedies.  The Securities shall have the Events
of Default as set forth in Section 5.01 of the Indenture.  Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the holders of at least 25% in aggregate
principal amount of the then outstanding Securities by notice to the Company and
the Trustee may declare all the Securities to be due and payable immediately.

          The holders of a majority in principal amount of the Securities then
outstanding by written notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration.  Holders may not enforce the Indenture or the Securities except as
provided in the Indenture.  Subject to certain limitations, holders of a
majority in principal amount of the then outstanding Securities issued under the
Indenture may direct the Trustee in its exercise of any trust or power.  The
Securities are unsecured general obligations of the Company.  The Company must
furnish annually compliance certificates to the Trustee.  The above description
of Events of Default and remedies

                                     A-11
<PAGE>   113
                                      12

is qualified by reference to, and subject in  its entirety by, the more 
complete description thereof contained in the Indenture.

          (12)     Amendments, Supplements and Waivers.  The Indenture permits,
with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders of the Securities under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of a majority in aggregate principal
amount of the Securities at the time Outstanding.  The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

          (13)     Trustee Dealings with the Company.  The Trustee, in its
individual or any other capacity may become the owner or pledgee of the
Securities and may otherwise deal with the Company or an Affiliate with the same
rights it would have, as if it were not Trustee, subject to certain limitations
provided for in the Indenture and in the TIA.  Any Agent may do the same with
like rights.

          (14)     No Recourse Against Others.  A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation.  Each Holder of the Securities by accepting a Security waives and
releases all such liability.  The waiver and release are part of the
consideration for the issue of the Securities.

          (15)     Governing Law.  THE INTERNAL LAWS OF THE STATE OF NEW YORK
SHALL GOVERN THE INDENTURE AND THE SECURITIES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

          (16)     Authentication.  The Securities shall not be valid until
authenticated by the manual signature of an authorized officer of the Trustee or
an authenticating agent.

          This PREFERRED SECURITIES GUARANTEE AGREEMENT (the "Preferred
Securities Guarantee"), dated as of [          ], 1997, is executed and
delivered by Walbro Corporation, a Delaware corporation (the "Guarantor"), and
[                               ], as trustee (the "Preferred Guarantee

                         DEFINITIONS AND INTERPRETATION

requires:

          (a)  Capitalized terms used in this Preferred Securities Guarantee
               but not defined in the preamble above have the respective
               meanings assigned to them in this Section 1.1;

          (b)  terms defined in the Declaration as at the date hereof have
               the same meaning when used in this Preferred Securities Guarantee
               unless otherwise defined in this Preferred Securities Guarantee;

          (c)  a term defined anywhere in this Preferred Securities

          condition at least annually, pursuant to law or to the requirements of
          the supervising or examining authority referred to above, then, for
          the purposes of this Section 4.1(a)(ii), the combined capital and
          surplus of such corporation shall be deemed to be its combined capital
          and surplus as set forth in its most recent report of condition so
          published.

     (b)  If at any time the Preferred Guarantee Trustee shall cease to be

Indenture Act, the Preferred Guarantee Trustee and Guarantor shall in all
respects comply with the provisions of Section 310(b) of the Trust Indenture
Act.

SECTION 4.2  Appointment, Removal and Resignation of
             Preferred Guarantee Trustee.

appointed or removed without cause at any time by the Guarantor.

     (b)  The Preferred Guarantee Trustee shall not be removed in accordance

from office (without need for prior or subsequent accounting) by an instrument
in writing executed by the Preferred Guarantee Trustee and delivered to the
Guarantor, which resignation shall not take effect until a Successor Preferred
Guarantee Trustee has been appointed and has accepted such appointment by

<PAGE>   18
                                      -15-

Trustee.  Such court may thereupon, after prescribing such notice, if any, as it
may deem proper, appoint a Successor Preferred Guarantee Trustee.

     (e)  No Preferred Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Preferred Guarantee Trustee.

     (f)  Upon termination of this Preferred Securities Guarantee or removal
or resignation of the Preferred Guarantee Trustee pursuant to this Section 4.2,
the Guarantor shall pay to the Preferred Guarantee Trustee all amounts accrued

SECTION 5.1  Guarantee.

     The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders (except to the extent paid by the  Trust), as and when due, regardless
of any defense, right of set-off or counterclaim that the Trust may have or
assert, the Guarantee Payments, without duplication.  The Guarantor's obligation
to make a Guarantee Payment may be satisfied by direct payment of the required
amounts by the Guarantor to the Holders or by causing the Trust to pay such
amounts to the Holders.

SECTION 5.2  Subordination.

     If an Event of Default (as defined in the Indenture) has occurred and is
continuing, the rights of Holders of Common Securities to receive Guarantee
Payments under the Common Securities Guarantee are subordinate to the rights of

Securities Guarantee.

notices and demands.

     The obligations, covenants, agreements and duties of the Guarantor under
this Preferred Securities Guarantee shall in no way be affected or impaired by
reason of the happening from time to time of any of the following:

     (a)  the release or waiver, by operation of law or otherwise, of the
performance or observance by the Trust of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Trust;

     (b)  the extension of time for the payment by the Trust of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time  for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Debentures or any extension of the maturity date of the Debentures permitted
by the Indenture),

     (c)  any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Trust granting indulgence or extension of any
kind;

     (d)  the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of

<PAGE>   20
                                      -17-


     debt of, or other similar proceedings affecting, the Trust or any of the
     assets of the Trust;

     (e)  any invalidity of, or defect or deficiency in, the Preferred
Securities;

     (f)  the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

     (g)  any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.4 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

     There shall be no obligation of the Holders or any other Persons to give
notice to, or obtain consent of, the Guarantor with respect to the happening of
any of the foregoing.

SECTION 5.5  Rights of Holders.

     (a)  The Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting of
any proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of this Preferred Securities Guarantee or to direct the exercise of any
trust or power conferred upon the Preferred Guarantee Trustee under this
Preferred Securities Guarantee.

     (b)  Any Holder may directly institute a legal proceeding against the
Guarantor to enforce the obligations of the Guarantor under this Preferred
Securities Guarantee without first instituting a legal proceeding against the
Trust, the Preferred Guarantee Trustee or any other Person.

     (c)  If an Event of Default with respect to the Debentures (an
"Indenture Event of Default"), constituting the failure to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable has occurred and is continuing, then a Holder of Preferred Securities
may directly, at any time, institute a proceeding for enforcement of payment to
such Holder of the principal of or interest on the 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

<PAGE>   21
                                      -18-

the Debentures.  The Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures
unless the Institutional Trustee (as defined in the Indenture) fails to do so.

SECTION 5.6  Guarantee of Payment.

     This Preferred Securities Guarantee creates a guarantee of payment and not
of collection.

SECTION 5.7  Subrogation.

     The Guarantor shall be subrogated to all, if any, rights of the Holders
against the Trust in respect of any amounts paid to such Holders by the
Guarantor under this Preferred Securities Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any right that it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Preferred Securities Guarantee, if, at the time
of any such payment, any amounts are due and unpaid under this Preferred
Securities Guarantee.  If any amount shall be paid to the Guarantor in violation
of the preceding sentence, the Guarantor agrees to hold such amount in trust for
the Holders and to pay over such amount to the Holders.

SECTION 5.8  Independent Obligations.

of the obligations of the Trust with  respect to the Preferred Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Preferred Securities Guarantee
notwithstanding the occurrence of any event referred to in subsections (a)
through (g) inclusive, of Section 5.4 hereof.

by extending the interest payment period and such extension shall be continuing,

Securities Guarantee or (iii) any event that, with the giving of notice or the
lapse of time or both, would constitute an Event of Default under the Indenture,
then the Guarantor shall not (a) declare or pay dividends on, or make a
distribution with respect to, or redeem, purchase, 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

security requiring the Guarantor to purchase shares of common stock, (ii) as a

if any, on or repay, repurchase or redeem debt securities of the Guarantor
(including guarantees) that rank pari passu with or junior to the Debentures or
(c) make any guarantee payments with respect  to the foregoing (other than
pursuant to this Preferred Securities Guarantee and the Common Securities
Guarantee).

SECTION 6.2  Ranking.

     (a)  This Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior to all
other liabilities of the Guarantor except any liabilities that may be pari passu
expressly by their terms, (ii) pari passu with the most senior preferred stock
or preference issued from time to time by the Guarantor and with any guarantee
now or hereafter entered into by the Guarantor in respect of any preferred or
preference stock or 


<PAGE>   23
                                      -20-

preferred securities of any Affiliate of the Guarantor, and (iii) senior to the
Guarantor's common stock.

     (b)  The holders of any obligations of the Guarantor that are senior in
priority to the obligations under this Preferred Securities Guarantee will be
entitled to all of the rights inuring to the holders of "Senior Indebtedness"
under Article 12 of the Indenture, and the Holders of the Preferred Securities
will be subject to all of the terms and conditions of such Article 12 with
respect to any claims or rights hereunder with the same effect as though fully
set forth herein.

stock to such Holder in respect of conversion of such Holder's Preferred
Securities into common stock of the Guarantor.  This Preferred Securities
Guarantee also will terminate completely upon full payment of the amounts
payable in accordance with the Declaration of the Trust.  This Preferred
Securities Guarantee will continue to be effective or will be reinstated, as the
case may be, if at any time any Holder must restore payment of any sums paid
under such Preferred Securities or under this Preferred Securities Guarantee.

incurred without negligence or bad faith on its part, arising out of or in

hereunder, including the costs and expenses (including reasonable legal fees and

in connection with the exercise or performance of any of its powers or duties
hereunder.  The obligation to indemnify as set forth in this Section 8.2 shall
survive the termination of this Preferred Securities Guarantee.

Cass City, Michigan  48726

  Re:  Walbro Corporation; Walbro Capital Trust;
   Registration Statement on Form S-3 (Registration No. 333-18317)

Ladies and Gentlemen:

  We have acted as special counsel to Walbro Capital Trust, a statutory
business trust created under the Business Trust Act of the State of Delaware
(Del. Code Ann., tit. 12, Section 3810) (the "Trust"), and Walbro Corporation,
a Delaware corporation (the "Company"), in connection with the preparation of
the Registration Statement (as defined below) for the registration under the
Securities Act of 1933, as amended (the "Act"), of (i) 2,300,000 Convertible
Trust Preferred Securities (the "Preferred Securities") (liquidation amount $25
per Convertible Trust Preferred Security) of the Trust, (ii) $57,500,000
aggregate principal amount of     % Convertible Subordinated Debentures due
2017 of the Company (the "Debentures"), (iii) shares of Common Stock, par value
$.50 per share (the "Common Stock"), of the Company initially issuable upon
conversion of the Debentures and the Preferred Securities (the "Conversion
Shares") and (iv) the rights of holders of the Preferred Securities under a
guarantee (the "Preferred Securities Guarantee") by the Company.

  The Preferred Securities are to be issued pursuant to an Amended and Restated
Declaration of Trust of the Trust (the "Declaration"), among the Company, as
sponsor and as the issuer of the Debentures to be held by the Institutional
Trustee (as defined below) of the Trust, Bankers Trust (Delaware), as Delaware
trustee, Bankers Trust Company, as institutional trustee (the "Institutional
Trustee"), and each of Lambert E.  Althaver, Daniel L. Hittler and Michael A.
Shope, as regular trustees.  The Preferred Securities Guarantee will be issued
pursuant to a Preferred Securities Guarantee Agreement (the "Guarantee
Agreement") by the Company, as guarantor.  In connection with any conversion of
a Preferred Security by the holder thereof, such Preferred Security will be
exchanged for the appropriate principal amount of Debentures held by the Trust,
which will, in turn, be immediately converted into shares of
<PAGE>   2

Common Stock at the then applicable rate, as further described in the
Declaration and the Indenture (as defined below).

  This opinion is being delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Act.  Capitalized terms used but not
otherwise defined herein have the meanings ascribed to them in the Registration
Statement.

  In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Registration
Statement on Form S-3 (Registration No. 333-18317) filed by the Company and the
Trust with the Securities and Exchange Commission (the "Commission") on
December 20, 1996 under the Act and Amendment No. 1 thereto filed with the
Commission on January 7, 1997 (such Registration Statement, as so amended,
being hereinafter referred to as the "Registration Statement"); (ii) the
Certificate of Trust of the Trust filed with the Secretary of State of the
State of Delaware on December 17, 1996; (iii) the form of the Declaration
(including the designations of the terms of the Preferred Securities annexed
thereto); (iv) the form of the Preferred Securities and specimen certificates
thereof; (v) the form of the Guarantee Agreement; (vi) the form of the
indenture (the "Indenture"), between the Company and Bankers Trust Company, as
indenture trustee, pursuant to which the Debentures will be issued; (vii) a
specimen Debenture; (viii) a specimen certificate representing the Common
Stock; (ix) the form of the Underwriting Agreement (the "Underwriting
Agreement") proposed to be entered into among the Company, the Trust and Smith
Barney Inc. and Interstate/Johnson Lane Corporation (collectively, the
"Underwriters") relating to, among other things, the sale of the Preferred
Securities; (x) the Restated Certificate of Incorporation of the Company, as
presently in effect; (xi) the By-Laws of the Company, as presently in effect;
and (xii) certain resolutions of the Board of Directors of the Company relating
to the issuance and sale of the Debentures and the Preferred Securities and
related matters.  We have also examined originals or copies, certified or
otherwise identified to our satisfaction, of such other documents, certificates
and records as we have deemed necessary or appropriate as a basis for the
opinions set forth herein.

  In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such copies.  In making our examination of
documents executed by parties other than the Company and the Trust, we have
assumed that such parties had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other, and execution and delivery by
such parties of such documents and that, except to the extent set forth in
paragraphs (2) and (3) below, such documents constitute valid and binding
obligations of such parties.  In addition, we have assumed that the
Declaration, the Preferred

Securities, the Guarantee Agreement, the Indenture, the Debenture and the
Underwriting Agreement when executed will be in substantially the forms
reviewed by us.  As to any facts material to the opinions expressed herein
which were not independently established or verified, we have relied upon oral
or written statements and representations of officers, trustees and other
representatives of the Company, the Trust and others.

  Members of our firm are admitted to the bar in the State of Illinois, and we
do not express any opinion as to the laws of any jurisdiction other than the
laws of the States of Illinois and Delaware and the federal laws of the United
States to the extent set forth herein.  To the extent that the opinions set
forth below relate to matters under the laws of the State of Delaware other
than the General Corporation Law of the State of Delaware, we have relied on
the opinion of Richards, Layton & Finger.

  Based on and subject to the foregoing and to the other qualifications and
limitations set forth herein, we are of the opinion that when (i) the
Registration Statement becomes effective; (ii) the price at which the Preferred
Securities are to be sold to the Underwriters pursuant to the Underwriting
Agreement and other matters relating to the issuance and sale of the Preferred
Securities and the Debentures have been duly adopted by the Pricing Committee
of the Board of Directors of the Company; (iii) the Declaration, the
Underwriting Agreement, the Guarantee Agreement, the Indenture and a purchase
agreement by and between the Company and the Trust relating to the sale of the
Debentures (the "Debenture Purchase Agreement") have been duly executed and
delivered by the parties thereto; (iv) the Preferred Securities have been duly
executed and authenticated in accordance with the terms of the Declaration and
delivered to and paid for by the Underwriters as contemplated by the
Underwriting Agreement; and (v) the Debentures have been duly executed and
authenticated in accordance with the terms of the Indenture and delivered to
and paid for by the Trust as contemplated by the Debenture Purchase Agreement
and the Declaration:

  1. The issuance and sale of the Preferred Securities will have been duly
authorized, and the Preferred Securities will be validly issued, fully paid and
nonassessable, representing undivided beneficial ownership interests in the
assets of the Trust; and the holders of such Preferred Securities will be
entitled to the same limitation of personal liability extended to stockholders
of private corporations for profit organized under the General Corporation Law
of the State of Delaware.  We bring to your attention, however, that the
holders of Preferred Securities may be obligated, pursuant to the Declaration
to (i) provide indemnity and/or security in connection with and pay taxes or
governmental charges arising from transfers of Preferred Securities and (ii)
provide security and indemnity in connection with the requests of or directions
to the Institutional Trustee to exercise its rights and powers under the
Declaration.

  2. The Guarantee Agreement will be a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except
to the extent that enforcement thereof may be limited by (i) bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter
in effect relating to creditors' rights generally and (ii) general principles
of equity (regardless of whether enforceability is considered in a proceeding
at law or in equity).

  3. The issuance and sale of the Debentures will have been duly authorized and
the Debentures will be valid and binding obligations of the Company, entitled
to the benefits of the Indenture and enforceable against the Company in
accordance with their terms, except to the extent that enforcement thereof may
be limited by (i) bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights generally
and (ii) general principles of equity (regardless of whether enforceability is
considered in a proceeding at law or in equity) and except that the waiver of
stay or extension laws contained in the Indenture may be unenforceable.

  4. The Conversion Shares, when certificates representing the Conversion
Shares in the form of the specimen certificates examined by us have been
manually signed by an authorized officer of the transfer agent and registrar
for the Common Stock and registered by such transfer agent and registrar and
delivered to the holders of the Preferred Securities upon conversion thereof in
accordance with the terms of the Declaration and the Indenture, will have been
duly authorized, and the Conversion Shares will be validly issued, fully paid
and nonassessable.

  We hereby consent to the use of our name under the heading "Legal Matters" in
the prospectus which forms a part of the Registration Statement.  We also
hereby consent to the filing of this opinion with the Commission as an exhibit

     Re: Walbro Capital Trust

Ladies and Gentlemen:

          We have acted as special Delaware counsel for Walbro Corporation, a
Delaware corporation (the "Company"), and Walbro Capital Trust, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
At your request, this opinion is being furnished to you.

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a)  The Certificate of Trust of the Trust, dated as of December 17,
1996 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on December 17, 1996;

          (b)  The Declaration of Trust of the Trust, dated as of December 17,
1996, among the Company, as Sponsor, and the trustee of the Trust named therein;

          (c)   Amendment No. 1 to the Registration Statement (the "Registration
Statement") on Form S-3, including a preliminary prospectus (the "Prospectus"),
relating to the __% Convertible Trust Preferred Securities of the Trust
representing preferred undivided beneficial interests in the assets of the Trust
(each, a "Preferred Security" and collectively, the "Preferred Securities"), as
proposed to be filed by the Company and the Trust with the Securities and
Exchange Commission on or about January 7, 1997;

          (d)  A form of Amended and Restated Declaration of Trust of the Trust,
to be entered into among the Company, as Sponsor, the trustees of the Trust
named therein, and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust (including Annex I and Exhibits A-1 and A-2
thereto) (the "Declaration"), attached as an exhibit to the Registration
Statement; and

          (e)   A Certificate of Good Standing for the Trust, dated January 7,
1997, obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Declaration.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (e) above.  In particular,
we have not reviewed any document (other than the documents listed in paragraphs
(a) through (e) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

          For purposes of this opinion, we have assumed (i) that the Declaration
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation and
termination of the Trust, and that the Declaration and the Certificate are in
full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due creation or due

organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by
us, (iv) that each of the parties to the documents examined by us has the power
and authority to execute and deliver, and to perform its obligations under,
such documents, (v) the due authorization, execution and delivery by all
parties thereto of all documents examined by us, (vi) the receipt by each
Person to whom a Preferred Security is to be issued by the Trust (collectively,
the "Preferred Security Holders") of a Preferred Security Certificate for such
Preferred Security and the payment for the Preferred Security acquired by it,
in accordance with the Declaration and the Registration Statement, and (vii)
that the Preferred Securities are issued and sold to the Preferred Security
Holders in accordance with the Declaration and the Registration Statement.  We
have not participated in the preparation of the Registration Statement and
assume no responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Business Trust Act.

          2.  The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.   The Preferred Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Declaration.

  Re:  Walbro Corporation; Walbro Capital Trust;
       Registration Statement on Form S-3 (Registration No. 333-18317)
 
Ladies and Gentlemen:

  We have acted as special tax counsel for Walbro Corporation, a Delaware
corporation (the "Company"), and Walbro Capital Trust, a statutory business
trust organized under the Business Trust Act of the State of Delaware (Del.
Code Ann., Tit. 12, Section 3810) (the "Trust"), in connection with the
preparation of the Registration Statement (as defined below) for registration
under the Securities Act of 1933, as amended (the "Act") of (i) 2,300,000
Convertible Trust Preferred Securities (the "Preferred Securities")
(liquidation amount of $25 per Preferred Security) of the Trust, (ii)
$57,500,000 aggregate principal amount of Convertible Subordinated Debentures
due 2017 of the Company (the "Debentures"), (iii) shares of Common Stock, par
value $.50 per share (the "Common Stock") of the Company issuable upon
conversion of the Preferred Securities, including such number of additional
shares of Common Stock as may be issuable upon conversion of the Preferred
Securities pursuant to anti-dilution adjustments (collectively, the "Conversion
Shares"), and (iv) the rights of holders of the Preferred Securities under a
guarantee (the "Preferred Securities Guarantee") and certain backup
undertakings consisting of obligations of the Company to provide certain
indemnities in respect of, and to pay and to be responsible for certain
expenses and debts of, the Trust as described in the Registration Statement.

  The Preferred Securities are guaranteed (the "Preferred Securities
Guarantee") by the Company with respect to the payment of distributions and
payments upon liquidation, redemption and otherwise pursuant to, and to the
extent set forth in, the Preferred Securities Guarantee Agreement ("Preferred
Securities Guarantee Agreement"), between the Company and Bankers Trust
Company, for the benefit of the holders of the Preferred Securities.

<PAGE>   2

Walbro Capital Trust

  In connection with the issuance of the Preferred Securities, the Trust is
also issuing its convertible common securities (liquidation amount of $25 per
convertible common security) (the "Common Securities"), representing undivided
beneficial interests in the assets of the Trust.  The Common Securities are
also guaranteed by the Company with respect to the payment of distributions and
payments upon liquidation, redemption and otherwise pursuant to, and to the
extent set forth in the Common Securities Guarantee Agreement ("Common
Securities Guarantee Agreement"), between the Company and Bankers Trust
Company, for the benefit of the holders of the Common Securities.

  The Preferred Securities and the Common Securities are being issued pursuant
to the Amended and Restated Declaration of Trust of the Trust (the
"Declaration"), among the Company, as sponsor and as the issuer of the
Debentures to be held by the Institutional Trustee (as defined below) of the
Trust, Bankers Trust (Delaware), as Delaware trustee, Bankers Trust Company, as
institutional trustee (the "Institutional Trustee"), and Lambert E. Althaver,
Daniel L. Hittler, and Michael A. Shope, as regular trustees.

  The entire proceeds from the sale of the Preferred Securities and the Common
Securities are to be used by the Trust to purchase the Debentures.  The
Debentures are to be issued pursuant to an Indenture (the "Indenture") between
the Company and Bankers Trust Company, as trustee (the "Indenture Trustee").

  In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction of (i) the Registration
Statement on Form S-3 (Registration No. 333-18317) filed by the Company and the
Trust with the Securities and Exchange Commission (the "Commission") on
December 20, 1996, under the Act, and Amendment No. 1 thereto filed with the
Commission on January 7, 1997 (such Registration Statement, as so amended,
being hereinafter referred to as the "Registration Statement"); (ii) the
certificate of trust of the Trust (the "Certificate of Trust") filed by the
Trust with the Secretary of State of Delaware on December 17, 1996; (iii) the
form of Declaration (including the designations of the terms of the Preferred
Securities annexed thereto); (iv) the form of the Preferred Securities
Guarantee Agreement; (v) the form of the Indenture; (vi) the form of Debentures
and a specimen certificate thereof; (vii) a specimen certificate representing
the Common Stock; (viii) the form of the underwriting agreement proposed to be
entered into among the Company, the Trust, Smith Barney Inc., and
Interstate/Johnson Lane Corporation (the "Underwriting Agreement"); and (ix)
the form of the Preferred Securities and a specimen certificate thereof.
Furthermore, we have relied upon certain statements and representations made by
officers of the Company.  We have also examined originals or copies, certified
or otherwise identified to our satisfaction, of such records of the Trust and
the Company and such other documents, certificates and records as we have
deemed necessary or appropriate as a basis for the opinions set forth herein.

  In rendering our opinion, we have participated in the preparation of the
Registration Statement.  Our opinion is conditioned on, among other things, the
initial and continuing accuracy of the facts, information, covenants and
representations set forth in the documents referred to above and the statements
and representations made by the Company and the Trust.  In our examination, we
have assumed the genuineness of all signatures, the legal capacity of all
natural persons, the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies and the authenticity of the originals of
such copies.  We also have assumed that the Declaration, the Preferred
Securities, the Guarantee Agreement, the Convertible Debentures, the Indenture
and the Conversion Shares will be executed in substantially the form reviewed
by us and that the transactions related to the issuance of the Preferred
Securities, the Common Securities, the Convertible Debentures, and the
Conversion Shares will be consummated in the manner contemplated by the
Registration Statement.

  In rendering our opinion, we have considered the current provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations
(proposed, temporary and final) promulgated thereunder, judicial decisions and
Internal Revenue Service rulings, all of which are subject to change, which
changes may be retroactively applied.  A change in the authorities upon which
our opinion is based could affect our conclusions.  Moreover, there can be no
assurances that any of the opinions expressed herein will be accepted by the
Internal Revenue Service or, if challenged, by a court.

  Based solely upon the foregoing, we are of the opinion that under current
United States federal income tax law:

  (1)  The Trust will be classified as a grantor trust and not as an
       association taxable as a corporation.

  (2)  Subject to the qualifications set forth therein, the statements made in
       the Registration Statement set forth under the captions "United States
       Federal Income Taxation", "Risk Factors -- Company Option to Extend
       Interest Payment Periods; OID Risk", "Risk Factors -- Proposed Tax
       Legislation", and "Description of the Convertible Debentures -- Proposed
       Tax Legislation" fairly present, in all material respects, the principal
       United States federal income tax consequences of an investment in the
       Convertible Preferred Securities.

  Except as set forth above, we express no opinion to any party as to the tax
consequences, whether federal, state, local or foreign, of the issuance of the
Convertible Debentures, the Preferred Securities, the Common Securities or of
any transactions related to or contemplated

by such issuance.  This opinion is solely for your benefit in connection with
the filing of the Registration Statement and, except as set forth below, is not
to be used, circulated, quoted or otherwise referred to for any purpose without
our prior written consent.  We hereby consent to the use of our name under the
heading "Legal Matters" in the Registration Statement.  We also hereby consent
to the filing of this opinion with the Commission as an exhibit to the
Registration Statement.  In giving this consent, we do not thereby admit that
we are within the category of persons whose consent is required under Section 7
of the Act or the rules and regulations of the Commission promulgated

expressly stated, and we disclaim any undertaking to advise you of any
subsequent changes of the facts stated or assumed herein or any subsequent
changes in applicable law.
