PART I

ITEM 1.  BUSINESS:

   Hercules Incorporated ("Hercules" or the "company") is a diversified,
worldwide producer of chemicals and related products. The company was
incorporated in Delaware in 1912. During 1998, Hercules made five major
acquisitions with combined annual revenues of approximately $1,600 million. The
largest of these was BetzDearborn Inc., a global specialty chemical company
providing water and process treatment to a variety of commercial and industrial
processes. This acquisition not only adds a new franchise to Hercules'
portfolio, it transforms Hercules' paper chemicals business into a full service
provider to the pulp and paper industry. BetzDearborn's 1997 reported revenues
were $1,295 million. This business is included in the Process Chemicals and
Services segment. The other four acquisitions and the segments in which they are
reported are as follows: Houghton International's paper chemicals group (Process
Chemicals and Services); Citrus Colloids, a pectin manufacturer (Functional
Products); Alliance Technical Products, a manufacturer of resins serving the
water-based adhesives industry (Chemical Specialties); and the 49% share of
FiberVisions owned by Hercules' joint venture partner, making it a wholly owned
subsidiary of Hercules. This business is the world's largest producer of
thermal-bond fiber for disposable diapers and other hygienic products and is
included in the Chemical Specialties segment. In 1997, the company joint
ventured this business and retained a 51% ownership interest. The joint venture
was accounted for under the equity method. Hercules divested its Composite
Products Division (which produced graphite fiber) in 1996 and its Aerospace and
Electronics and Printing businesses in 1995. Accordingly, information related to
divested businesses has been omitted in this Form 10-K, except where relevant.

REPORTABLE SEGMENTS

     Hercules operates, both domestically and throughout the world, in three
reportable segments: Process Chemicals and Services, Functional Products, and
Chemical Specialties. The financial information regarding Hercules' segments,
which includes net sales and profit from operations for each of the three years
in the period ended December 31, 1998 and capital employed as of December 31,
1998, 1997, and 1996, is provided in Note 24 to the Consolidated Financial
Statements. See Part II, Item 8.

     Information regarding principal products produced and sold by each segment
and principal markets served by each segment is presented in the columns so
designated in the segment table presented below. These products are sold
directly to customers from plants and warehouses, as well as being sold in some
cases (particularly in markets outside the United States) to and through
distributors.

     Results of divested businesses (where applicable) are included in
"reconciling items" for segment financial reporting.

     In general, Hercules does not produce against a backlog of firm orders;
production is geared primarily to the level of incoming orders and the
projections of future demand. Inventories of finished products, work in process,
and raw materials are maintained to meet delivery requirements of customers and
Hercules' production schedules.

     The businesses of each of the segments are not seasonal to any significant
extent.

RAW MATERIALS AND ENERGY

     Raw materials and supplies are purchased from a variety of industry
sources, including agricultural, forestry, mining, petroleum, and chemical
industries.

     Important raw materials for the Process Chemicals and Services segment are
cationic and anionic polyacrylamides and emulsions, biocides, amines,
surfactants, rosin, adipic acid, epichlorohydrin, fumaric acid, stearic acid,
diethylenetriamine, phosphorus trichloride, wax and starch.

     Raw materials important to the Functional Products segment are
acetaldehyde, fatty acids, chemical cotton, woodpulp, ethyl chloride, alcohols,
chlorine, ethylene oxide, propylene oxide, monochloroacetic acid, methyl
chloride, caustic, inorganic acids, fruit and floral extracts, guar splits,
seaweed, terpenes, and citrus peel.

     The important raw materials for the Chemical Specialties segment are
ketones, alcohols, phenol, adipic acid, epichlorohydrin, fumaric acid, stearic
acid, diethylenetriamine, phosphorus trichloride, wax, casein, starch, pigments,
antioxidants, d-limonene, turpentine, crude tall oil, rosin, pine wood stumps,
aromatic and aliphatic resin formers, cumene, catalysts, pure monomers, toluene,
clay, process oils, and polypropylene resin.

     Major requirements for key raw materials and fuels are typically purchased
pursuant to multi-year contracts. Hercules is not dependent on any one supplier
for a material amount of its raw material or fuel requirements, but certain
important raw materials are obtained from sole-source or a few major suppliers.

     While temporary shortages of raw materials and fuels may occur
occasionally, these items are currently readily available. However, their
continuing availability and price are subject to domestic and world market and
political conditions as well as to the direct or indirect effect of United
States Government regulations. The impact of any future raw material and energy
shortages on Hercules' business as a whole or in specific world areas cannot be
accurately predicted. Operations and products may, at times, be adversely
affected by legislation, shortages or international or domestic events.

COMPETITION

     Hercules encounters substantial competition in each of its three segments.
This competition, from other manufacturers of the same products and from
manufacturers of different products designed for the same uses, is expected to
continue in both the United States and markets outside the United States. Some
of Hercules' competitors, such as companies engaged in petroleum operations,
have more direct access to raw materials, and some have greater financial
resources than Hercules.

The number of Hercules' principal competitors varies from product to product. It
is not practicable to estimate the number of all competitors because of the
large variety of Hercules' products, the markets served and the worldwide
business interests of Hercules.

PATENTS AND TRADEMARKS

     Patents covering a variety of products and processes have been issued to
Hercules and its assignees. In addition, Hercules is licensed under certain
other patents covering its products and processes. Taken as a whole, the rights
of Hercules under these patents and licenses, which expire from time to time,
are considered by Hercules to constitute a valuable asset. However, Hercules
does not consider any single patent or license, or any group thereof related to
a specific product or process, to be of material importance to its business as a
whole.

     Hercules or its wholly owned subsidiaries also have registered trademarks
for a number of its products. Some of the more significant trademarks include:
AQUAPEL(R) sizing agent, HERCON(R) sizing emulsions, KYMENE(R) resin,
REGALREZ(R) resin, AQUALON(R) water-soluble polymers, SLENDID(R) fat replacer,
NATROSOL(R) hydroxyethylcellulose, CULMINAL(R) methylcellulose, KLUCEL(R)
hydroxypropylcellulose, NATROSOL FPS(R) water-soluble polymer suspension,
PRECIS(R) sizing agent, NOVUS(R) polymer, DIANODIC(R) cooling water products,
CONTINUUM(R) cooling water products, and Herculon(R) fiber.

RESEARCH AND DEVELOPMENT

     Research and development, which is directed toward the discovery and
development of new products and processes, the improvement and refinement of
existing products and processes and development of new applications for existing
products, is primarily company-sponsored. Hercules spent $61 million on research
activities during 1998, as compared to $53 million in 1997 and $56 million in
1996.

ENVIRONMENTAL MATTERS

     Hercules believes that it is in compliance in all material respects with
applicable federal, state, and local environmental laws and regulations.
Expenditures relating to environmental cleanup costs have not materially
affected, and are not expected to materially affect, capital expenditures or
competitive position. Additional information regarding environmental matters is
provided in Note 22 to the Consolidated Financial Statements.

EMPLOYEES

     As of December 31, 1998, Hercules had 12,357 employees worldwide.
Approximately 7,249 were located in the United States, and of these employees
about 18% were represented by various local or national unions.

INTERNATIONAL OPERATIONS

     Information on net sales and long-lived assets by geographic areas, for
each of the three years ended December 31, 1998, appears in Note 24 to the
Consolidated Financial Statements. Direct export sales from the United States to
unaffiliated customers were $319 million, $309 million, and $295 million for
1998, 1997, and 1996, respectively. Hercules' operations outside the United
States are subject to the usual risks and limitations related to investments in
foreign countries, such as fluctuations in currency values, exchange control
regulations, wage and price controls, employment regulations, effects of foreign
investment laws, governmental instability (including expropriation or
confiscation of assets) and other potentially detrimental domestic and foreign
governmental policies affecting United States companies doing business abroad.

     Hercules plants and facilities, which are continually added to and
modernized, are generally considered to be in good condition and adequate for
business operations. From time to time Hercules discontinues operations at, or
disposes of, facilities that have for one reason or another become unsuitable.


ITEM 3. LEGAL PROCEEDINGS:

     In September 1993, Hercules and the U.S. Environmental Protection Agency
(EPA) Region 1 reached an agreement in principle in settlement of the EPA's
claims that Hercules violated its wastewater permit with the City of Chicopee
and the Federal pretreatment standard for industrial users of publicly owned
treatment works at its Chicopee, Massachusetts facility. Hercules signed a
Consent Decree, which was entered by the court on December 15, 1994, based on
this agreement, requiring supplemental environmental projects (at a cost of
approximately $375,000), compliance with permit limits in the future, and
$250,000 in fines. Hercules has paid the $250,000 fine and has completed
performance of the supplemental environmental projects. On March 26, 1998, the
Court granted its approval for the termination of the Consent Decree.

     In December 1997, Hercules received notice of an enforcement action by the
State of Georgia, Environmental Protection Department (EPD). In the notice, EPD
requested that Hercules enter into a proposed Consent Order, alleged violations
of the Resource Conservation and Recovery Act (RCRA) and sought a civil penalty
of $250,000. Hercules, without admitting liability, has entered into a Consent
Order with the State of Georgia settling these claims. The Consent Order was
finalized and became effective in January 1999. The consent Order requires
Hercules to pay a fine of $80,000, install 3 aquaria in the Brunswick, Georgia
community, maintain the aquaria for 10 years and remediate certain soils that
are located at Hercules Brunswick, Georgia plant.

Environmental

         Hercules has been identified as a potentially responsible party (PRP)
by U.S. federal and state authorities, or has been sued for contribution by
private parties, for the cost of environmental investigation and/or cleanup at
numerous sites. The estimated range of the reasonably possible share of costs
for investigation and cleanup is between $63 million and $199 million. The
actual costs will depend upon numerous factors, including the number of parties
found responsible at each environmental site and their ability to pay, the
actual methods of remediation, outcomes of negotiations with regulatory
authorities, outcomes of litigation, changes in environmental laws and
regulations, technological developments, and the years of remedial activity
required, which could range up to 30 years.

         In 1992, Hercules brought suit against its insurance carriers for past
and future costs for cleanup of certain environmental sites. In April 1998, the
trial regarding insurance recovery for the Jacksonville, Arkansas site (see
discussion below) was completed. The jury returned a "Special Verdict Form" with
findings that will, in conjunction with the Court's other opinions, be used by
the Court to enter a judgment. The judgment will determine the amount of
Hercules recovery for past cleanup expenditures and will state that Hercules is
entitled to similar coverage for costs incurred since September 30, 1997 and in
the future. Hercules has not included any insurance recovery in the estimates
above.



                                       6
<PAGE>   7
         Hercules becomes aware of sites in which it may be, but has not yet
been named a PRP, principally through its knowledge of investigation of sites by
the U.S. Environmental Protection Agency (EPA) or other government agencies or
through correspondence with previously named PRPs requesting information on
Hercules' activities at sites under investigation. In addition, Hercules has
established procedures for identifying environmental issues at its respective
plant sites. Environmental coordinators, familiar with environmental laws and
regulations, are resources for identification of environmental issues. Further,
Hercules has environmental audit programs, which are designed to identify
environmental issues at operating plant sites. Through these programs and
information-gathering activities, Hercules identifies potential environmental,
regulatory, and remedial issues.

         Litigation over liability at Jacksonville, Arkansas, the most
significant site, has been pending since 1980. As a result of a pretrial Court
ruling in October 1993, Hercules has been held jointly and severally liable for
costs incurred, and for future remediation costs, at the Jacksonville site by
the District Court, Eastern District of Arkansas (the Court).

         Other defendants in this litigation have either settled with the
government or, in the case of the Department of Defense (DOD), have not been
held liable. Hercules appealed the Court's order finding the DOD not liable. On
January 31, 1995, the 8th Circuit Court of Appeals upheld the Court's order.
Hercules filed a petition to the U.S. Supreme Court requesting review and
reversal of the 8th Circuit Court ruling. This petition was denied on June 26,
1995, and the case was remanded to the District Court for further proceedings.

         On May 21, 1997, the Court issued a ruling that Uniroyal is liable and
that Standard Chlorine is not liable to Hercules for contribution. A trial on
allocation and damages among Hercules, Uniroyal, and the United States was
scheduled to begin October 1998. Through the filing of separate summary judgment
motions, Hercules and Uniroyal raised a number of defenses to the United States'
ability to recover its costs. On October 23, 1998, the Court denied those
motions and granted the United States' summary judgment motion, ordering
Hercules and Uniroyal to pay the United States approximately $103 million plus
any additional response costs incurred or to be incurred after July 31, 1997.
Hercules expects that this amount will be reduced by approximately $7 million,
the amount received by the United States in previous settlements with other
parties. Trial testimony on the issue of allocation between Hercules and
Uniroyal was completed on November 6, 1998. Once a final judgment has been
entered, Hercules expects to appeal the Court's determination with respect to
its liability, the United States' costs, the divisibility of harm issue, and
Standard Chlorine's liability.

         At December 31, 1998, the accrued liability for environmental
remediation represents management's best estimate of the probable and reasonably
estimable costs related to environmental remediation. The extent of liability is
evaluated quarterly. The measurement of the liability is evaluated based on
currently available information, including the process of remedial
investigations at each site and the current status of negotiations with
regulatory authorities regarding the method and extent of apportionment of costs
among other PRPs. Hercules does not anticipate that its financial condition will
be materially affected by environmental remediation costs in excess of amounts
accrued, although quarterly or annual operating results could be materially
affected.

Litigation

         The company is a defendant in numerous lawsuits that arise out of, and
are incidental to, the conduct of its business. In these legal proceedings, no
specifically identified director, officer, or affiliate is a party or a named
defendant. These suits concern issues such as product liability, contract
disputes, labor-related matters, patent infringement, environmental proceedings,
property damage, and personal injury matters.

         Hercules was a defendant in three Qui Tam (Whistle Blower) lawsuits in
the U.S. District Court for the Central District of Utah, brought by former
employees of the Aerospace business sold to Alliant Techsystems Inc. in March
1995. The first suit (United States of America ex. rel, Katherine A. Colunga v.
Hercules Incorporated, et al., Civil No. 89-C-954B), involved allegations
relating to submission of false claims and records under various government
contracts, delivery of defective products, a deficient quality control program,
and wrongful termination claims. The second suit (United States of America ex.
rel. Benny Hullinger, et al., Civil No. 92-CV-085) involved allegations relating
to submission of false claims and records, mischarging of work performed under
government contracts, misuse of government equipment, other acts of financial
mismanagement, and wrongful termination claims. The government, after
investigation of the allegations, declined to intervene in either lawsuit. (A
third Qui Tam lawsuit is described in the following paragraph.) The first
lawsuit was previously scheduled for trial in June 1998. The Court denied
various motions filed by Hercules, including motions for summary judgment and
other

                                       7
<PAGE>   8
motions designed to limit the scope of the trial and the extent of damages
claimed. If any damages had been awarded by the jury under the False Claims Act,
such damages would have been automatically tripled by the Court, and attorneys'
fees and costs would also have been added. As a result of the Court's denial of
Hercules' motions, and the Court's position as to how the relevant contracts
should be interpreted, which position was adverse to Hercules, damage claims
could have been presented to the jury in amounts which, if awarded, would have
had a material adverse effect on Hercules. The damages in the second suit were
not defined. In May 1998, Hercules announced that it had agreed to settle the
first lawsuit. Under the terms of the settlement, Hercules was obligated to pay
$36 million to settle the case, plus another $19 million to cover the
plaintiff's attorneys fees, expenses, and costs. Hercules believed no damages
were incurred by the government, no false claims were made to the government,
and alleged damages were speculative and unsupportable. However, because of the
mounting legal costs, the prospect of treble damages, uncertainty present in any
litigation, and to avoid the major costs of a lengthy trial and subsequent
appeal by the losing party, management determined that the settlement was in the
best interest of Hercules' shareholders. The settlement was approved by the
Court and the case was dismissed in July 1998. In August 1998, the parties to
the second lawsuit reached a tentative settlement, subject to approval of the
Court. Although it did not intervene in the case, the U.S. Department of Justice
(DOJ) objected to approval of the tentative settlement, arguing that Hercules
should only be released from claims that the government contended were actually
investigated, and that the proposed allocation of settlement proceeds between
False Claims Act claims and wrongful termination claims should be revised to
attribute a higher percentage of recovery to claims arising under the False
Claims Act. On February 9, 1999, the Court entered a judgment approving the
settlement and dismissing the lawsuit. The DOJ has 60 days from that date in
which to file a Notice of Appeal, if it chooses to do so. The settlement was
recognized in the first quarter 1998.

         In March 1995, Hercules sold its Aerospace business to Alliant
Techsystems, Inc. As part of the sale, Hercules received an ownership interest
in Alliant. In March 1997, Alliant and Hercules received a partially unsealed
complaint that named both as defendants, initiated on an unknown date, and filed
in an undisclosed federal Court, in a Qui Tam action by a former employee
alleging violations of the False Claims Act. The action was subsequently
identified as United States of America ex. rel. P. Robert Pratt v. Alliant
Techsystems, Inc and Hercules Incorporated, Civil No. 95-4812 SVW (JGx) in the
U.S. District Court for the Central District of California. The action alleged
labor mischarging at Alliant's Bacchus Works facility in Magna, Utah, and
contained a claim for wrongful termination. Damages were not specified, and
Alliant and Hercules agreed to share equally the cost of defense until such time
as a determination is made as to the applicability of the indemnification
provisions of the Purchase and Sale Agreement between Alliant and Hercules. In
February 1998, the parties reached a tentative settlement, which has since been
finalized, under which all claims alleging mischarging to the Intermediate
Nuclear Forces Contract were settled. The settlement was recognized in the
fourth quarter 1997. Other portions of the complaint, which included allegations
of mischarging to other government contracts and claims for wrongful termination
of employment were not resolved by the settlement. The government did not
intervene in these other matters. In August 1998, the parties reached a
tentative settlement of the remaining portions of the complaint, subject to
approval of the Court. The DOJ objected to approval of the tentative settlement,
arguing that Hercules should only be released from claims that the government
contended were actually investigated, and that the settlement agreement should
have contained certain provisions preventing Alliant from recovering certain
costs under its government contracts. On February 17, 1999, the Court entered a
judgment approving the settlement and dismissing the lawsuit. The DOJ has 60
days from that date in which to file a Notice of Appeal, if it chooses to do so.
The settlement was recognized in the first quarter 1998.

         In addition to the Jacksonville, Arkansas, site litigation described
above, two individuals have sued Hercules in a lawsuit captioned Jeffrey
Shelton, Jr., et al. v. Hercules Incorporated, Civil No. LR-C-97-131 (E.D. Ark.
1997). These individuals seek medical monitoring and damages for loss of
recreational opportunities. They have brought a Resource Conservation and
Recovery Act (RCRA) citizens suit against Hercules seeking an injunction which
would require Hercules to fund or perform various environmental and health
studies and pay for any required remediation to the Bayou Meto. Trial is
presently scheduled for August 1999. Further, 19 individuals have sued Hercules
in a matter entitled Gary Graham, et al. v. Vertac Chemical Corporation and
Hercules Incorporated, No. LR-C-98-678 (E.D. Ark. 1998). These individuals seek
damages for personal injuries and diminution of property value as a result of
alleged dioxin contamination from the Jacksonville site. Trial is presently
scheduled for August 1999. Hercules denies liability in both actions, and
Hercules intends to vigorously defend itself.

         BetzDearborn, along with Pacific Gas and Electric (PG&E), is a
defendant in four lawsuits involving in the aggregate approximately 2,350
plaintiffs pending in the Superior Court of Los Angeles County, California (the


                                       8
<PAGE>   9
Lawsuits). Plaintiffs are comprised primarily of present and former PG&E
employees, their families, and residents living in the vicinity of the three
PG&E facilities that are the subject of the Lawsuits. Plaintiffs seek
unspecified monetary damages (including punitive damages) for personal injuries
arising from alleged exposures to chromate-based products sold or allegedly sold
by Betz Laboratories, Inc. (predecessor to BetzDearborn) to PG&E for use in the
cooling towers located at these facilities. The sales in question occurred or
allegedly occurred at various times between 1952 and the mid-1980s, depending
upon the facility. In the Acosta, Aguilar, and Aguayo cases, the parties have
selected 20 plaintiffs and 2 alternates whose claims will be tried together, and
prior to the claims for the remaining plaintiffs in the Lawsuits. It is
anticipated that the 20 plaintiffs' claims will be tried in late 1999.
BetzDearborn denies any legal liability to plaintiffs, believes it has
substantial defenses, and intends to contest the claims vigorously. BetzDearborn
further believes that any claim for punitive damages is without any legitimate
basis in fact or law. The Lawsuits are captioned as follows: Acosta, et al. v.
Betz Laboratories, et al., No. BC 161 669 (1996); Adams, et al. v. Betz
Laboratories, et al., No. BC 113 000 (1994); Aguilar, et al. v. Betz
Laboratories, et al., No. BC 158 588 (1996); and Aguayo et al. v. Betz
Laboratories, et al., No. BC 123 749 (1995).

         Although both BetzDearborn and PG&E are named as defendants in each of
the Lawsuits, not all plaintiffs seek damages from both defendants. PG&E
previously settled a lawsuit brought by many of the same individuals who are
plaintiffs in the Adams lawsuit; as a result, PG&E will have no additional
liability to those plaintiffs.

         In October 1998, BetzDearborn and PG&E settled a fifth lawsuit relating
to alleged exposure to chromate-based products sold or allegedly sold by Betz
Laboratories, Inc. to PG&E for use in cooling towers at one or more of the PG&E
facilities. That lawsuit was captioned Riep, et al. v. Betz Laboratories, et
al., No. 984695 (San Francisco County, 1997). The amount of the settlement was
not material.

         BetzDearborn maintained insurance coverage for the purpose of securing
protection against alleged product and other liabilities, and certain of the
insurance carriers have undertaken to pay the cost of the defense of the
Lawsuits subject to various reservations of rights. BetzDearborn will pursue all
available insurance coverage to fund any damages payable to plaintiffs in
connection with the Lawsuits (excluding any punitive damages to the extent not
recoverable under BetzDearborn's insurance policies).

         While it is not feasible to predict the outcome of all pending suits
and claims, the ultimate resolution of these matters could have a material
effect upon the financial position of Hercules, and the resolution of any of the
matters during a specific period could have a material effect on the quarterly
or annual operating results for that period.

     No matter was submitted to a vote of security holders during the fourth

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATIONS:

This discussion should be read in connection with the information contained in
the Consolidated Financial Statements and Notes thereto.


ACQUISITIONS, DIVESTITURES, AND ONE-TIME ITEMS

In 1998, Hercules made five major acquisitions for an aggregate purchase price
of approximately $3,620 million, primarily in cash and assumed debt. (See Note
1.) These acquisitions were accounted for on the purchase method of accounting,
resulting in $2,531 million of goodwill and other intangible assets, and were
financed with borrowed funds. Total debt increased by $2,968 million in the same
period.

The combined annual revenue of the acquired businesses is approximately $1,600
million. The largest of these acquisitions was the purchase of BetzDearborn
Inc., a global specialty chemical company providing water and process treatment
to a variety of commercial and industrial processes. BetzDearborn reported 1997
revenue of approximately $1,295 million. This acquisition not only adds a new
franchise to Hercules' portfolio, it transforms Hercules' paper chemicals
business into a full service provider to the pulp and paper industry.
Additionally, the company acquired Houghton International's paper chemicals
group; Citrus Colloids, a pectin manufacturer; Alliance Technical Products, a
manufacturer of resins serving the water-based adhesives industry; and the 49%
share of FiberVisions owned by Hercules' joint venture partner, making it a
wholly owned subsidiary of Hercules.


                                       11
<PAGE>   12
This business is the world's largest producer of thermal-bond fiber for
disposable diapers and other hygienic products.

The results of operations of the acquired businesses are included in the
consolidated financial statements from the dates of acquisition. In 1998, these
businesses added $363 million and $41 million of revenue and operating profit,
respectively, after amortization of goodwill and intangible assets of $19
million, reflected in selling, general and administrative expenses. Interest and
debt expense increased significantly as a result of the increased debt.

Primarily as a result of the acquisitions, Hercules incurred charges of $232
million before taxes ($197 million net of income taxes) in the fourth quarter of
1998; $215 million is reflected in Profit from operations and $17 million is
reflected in Other income (expense). The largest portion of these charges is
$130 million for purchased in-process research and development related to the
acquisition of BetzDearborn. (See Note 14.) The remainder of the charges relates
to the company's plans and actions to integrate the operations of BetzDearborn
and improve the efficiencies of its existing operations and support activities.
Charges include employee termination benefits, exit costs related to facility
closures, write-downs of property, plant and equipment, integration expenses,
and contract terminations. (See Notes 15 and 17.) These actions are anticipated
to yield synergies of at least $125 million before taxes on an annual basis;
approximately half of these are expected to be realized by the end of 1999 and
the remainder by the end of 2000. Additional integration expenses are expected
to be incurred during 1999. Other income (expense) in 1998 also includes a $62
million charge from the settlements of long-standing "whistle-blower" lawsuits
related to the divested Aerospace business. (See Note 22.)

Other operating expenses in 1997 included charges of $167 million for asset
rationalizations and impairments, termination benefits primarily associated with
reorganization of management and the adoption of new competitive strategies, and
other costs. (See Note 15.) Additionally, Other income (expense) in 1997
reflects the following items: a $20 million charge related to acquisition
activity; a $32 million charge for legal settlements; and a $368 million gain
from the monetization of Hercules' investment in Tastemaker. (See Note 17.)

Profit from operations in 1996 included $13 million of probable environmental
recoveries, a $2 million favorable settlement of an environmental remediation
claim, and a $3 million favorable adjustment to spare parts inventories.

Hercules divested or joint ventured several businesses in 1996 and 1997.
Revenues and operating profits related to these businesses were $84 million and
$9 million, respectively, in 1997 and $286 million and $25 million,
respectively, in 1996.

SEGMENT REPORTING

In 1998, Hercules adopted Statement of Financial Accounting Standards (SFAS) No.
131, "Disclosures about Segments of an Enterprise and Related Information." (See
Note 24.) In compliance with SFAS 131 and as a result of the acquisition of
BetzDearborn, the company has identified three reportable segments and has
restated prior years to conform with the 1998 presentation. The three segments
are: Process Chemicals and Services, comprised of Pulp and Paper, and
BetzDearborn; Functional Products, comprised of Aqualon and Food Gums; and
Chemical Specialties, comprised of Resins and FiberVisions. Accordingly, the
segment comparisons provided herein are on the basis prescribed by this
standard.


RESULTS OF OPERATIONS

(All comparisons are with the previous year, unless otherwise stated.)

1998 vs. 1997:

Consolidated revenues increased $279 million or 15% as the increase in revenues
from acquisitions was partially offset by the effects of the economic crisis in
Southeast Asia, the strength of the U.S. dollar, and competitive pricing
pressures. Consolidated profit from operations declined $36 million or 16%.
However, after adjusting for the impact of the one-time items described in the
previous section, profit from operations increased $12 million or 3%, while
operating margins decreased from 21.2% in 1997 to 19.0% in 1998. These results
are due to the operating profit impact of the revenue variance noted above,
coupled with manufacturing cost improvement initiatives, partly offset by higher
selling, general, and administrative expenses.

Process Chemicals and Services segment revenues increased 62%, resulting from
acquisitions. Excluding acquisitions, revenues in this segment were negatively
impacted by competitive pricing pressures, the impact of


                                       12
<PAGE>   13
the economic crisis in Southeast Asia, and the weakness of foreign currencies
relative to the dollar. Profit from operations increased 31% as the favorable
impact of acquisitions was partly offset by the adverse revenue impacts
described above, higher raw material costs used in the production of wet
strength products in Europe, and higher selling, general, and administrative
expenses.

Functional Products segment revenues declined 4% on lower volumes, particularly
in Asia and Eastern Europe, and also the U.S. oilfield markets, along with the
negative impact of weaker foreign currencies relative to the dollar, partly
offset by acquired revenues and improved pectin pricing. Profit from operations
declined 4%. This was the result of improved manufacturing costs and pectin
pricing mitigating the volume declines and the negative impact of the weaker
foreign currencies noted above.

Chemical Specialties segment revenues increased 8% as the additional revenues
from acquisitions were partly offset by lower pricing across the major Resins
product lines both in the U.S. and in Europe. Profit from operations rose 12% as
the profit from acquisitions was partly offset by the pricing declines in
Resins.

1997 VS. 1996:

Consolidated revenues declined $194 million or 9%, primarily due to
divestitures, partly offset by generally higher volumes. Weaker foreign
currencies impacted consolidated sales $88 million, or 4%. Profit from
operations declined $213 million or 48%. Excluding divestitures and one-time
items described in the previous section, profit from operations decreased $12
million or 3%, on a comparable basis. Higher volumes and manufacturing cost
improvements were offset by weaker foreign currencies, which negatively impacted
consolidated profit from operations $19 million or 5%.

Process Chemicals and Services revenues decreased 2% as higher volume from
increased market share of wet strength products in Europe and in alkaline size
associated with stronger industry-wide operating rates were essentially offset
by regional competitive pricing pressure across all major product lines and
weaker foreign currencies relative to the dollar. Profit from operations
declined 7% primarily due to the effects of lower pricing, higher selling,
general, and administrative expense spending, along with the negative effect of
the weaker foreign currencies relative to the dollar. These negative impacts
were only partly offset by lower raw material costs in the production of
alkaline size and wet strength products and the beneficial impact of continuing
manufacturing cost improvement initiatives.

Functional Products revenues declined $26 million or 3% primarily due to the
divestiture of a business unit, generally softer pricing, and weaker foreign
currencies relative to the dollar. These declines were partly offset by higher
water-soluble polymers and food gums volumes in various applications. Profit
from operations increased $4 million or 2% as a result of the volume improvement
described above, along with manufacturing cost improvement initiatives partly
offset by the divested business.

Chemical Specialties revenues declined 17% primarily due to the formation of the
FiberVisions joint venture in June 1997, the divestiture of a business unit, and
weaker foreign currencies relative to the dollar, partly offset by Resins volume
improvements. Profit from operations decreased 29% primarily due to the
divestitures, higher manufacturing costs at several Resins plants resulting from
the introduction of new processes and operability issues, and the effect of the
weaker foreign currencies relative to the dollar.

Equity in income of affiliated companies declined in 1998 and in 1997 as a
result of the monetization of Hercules' investment in Alliant Techsystems in
1997 and 1998 and the monetization of Hercules' investment in Tastemaker in
1997. (See Note 21.)

The provision for income taxes reflects effective tax rates of 88% in 1998, 45%
in 1997 and 33% in 1996. Both the 1998 and 1997 rates are significantly higher
than the federal statutory income tax rate of 35%. The 1998 rate is high because
the charges for purchased in-process research and development and goodwill
amortization are not deductible for income tax purposes. The impact of these
nondeductible items was reduced by favorable state tax settlements relating to a
prior year's sale of an investment and favorable federal tax adjustments related
to prior years' assessments. The 1997 rate reflects the relatively higher tax
rate on the monetization of the Tastemaker and Alliant Techsystems investments,
along with required increases to tax reserves related to anticipated assessments
from federal, state, and foreign authorities. The 1996 rate was favorably
affected by tax loss carryforwards. The 1999 tax rate is anticipated to be
approximately 40%, reflecting the effects of the nondeductible goodwill.


                                       13

FINANCIAL CONDITION

Liquidity and financial resources: Net cash flow from operations was $181
million in 1998, $187 million in 1997, and $225 million in 1996. 1998 included
higher interest payments related to increased debt and higher payments of legal
settlements, offset by lower income tax payments and cash flow from acquired
businesses. 1997 decreased primarily from lower trade payables, severance
payments, and higher legal and environmental spending, partially offset by lower
tax payments.

As noted above, during 1998, the company completed five acquisitions for
approximately $3.62 billion, primarily in cash and assumed debt. The company
financed the acquisitions and refinanced existing debt with borrowings under a
$3.65 billion credit facility with a syndicate of banks. Borrowings consisted of
three tranches of varying maturity term loans totaling $2.75 billion due in
various amounts through December 2003. The facility bears interest at London
Interbank Offered Rate (LIBOR) plus 2% and may decrease to LIBOR plus .75% after
six months if a $500 million term-loan tranche has been repaid. The credit
facility includes a $900 million revolving credit agreement. The company's debt
agreement contains restrictive covenants that require maintenance of certain
financial covenants, including leverage, net worth, and interest coverage, and
provides that the entry of a judgment or judgments involving aggregate
liabilities of $50 million or more be vacated, discharged, stayed, or bonded
within 60 days of entry of such judgment or judgments.

In September 1998, the company filed a shelf registration to increase accessible
securities from $300 million to $3.0 billion. The registration allows for
issuance of equity, equity-like, and debt securities. In November 1998, a wholly
owned subsidiary of the company completed a private placement of units
consisting of $200 million in Trust-preferred securities and a forward
underwriting contract to purchase Hercules common stock. The Trust's obligation
is guaranteed by the company. (See Note 7.) The securities are expected to be
remarketed within 12 months of their issuance. Under certain circumstances,
Hercules may be required to redeem these securities. In addition, Hercules has
agreed to sell $200 million of Hercules common stock following the successful
remarketing or redemption of the securities.

In March 1999, another wholly owned subsidiary trust of the company commenced a
public offering, under the registration statement noted above, to sell $250
million of Trust Originated Preferred Securities. As an update to the foregoing,
the offering was over-subscribed and the Trust sold an aggregate of $362 million
of Trust Originated Preferred Securities on March 17, 1999. Proceeds of the
offering were used to repay long-term debt. The Trust's obligations will be
guaranteed by the company.

Issuance of Hercules common stock and the Trust Originated Preferred Securities,
in the updated amount, reduced the amount accessible under the shelf
registration to $2.438 billion. Hercules anticipates issuing additional
equity-like securities to repay long-term debt during 1999.

As of December 31, 1998, the company has $612 million available under the
revolving credit agreement and $219 million of short-term lines of credit.

Capital Structure and Commitments: Total capitalization (stockholders' equity,
trust-preferred securities, and debt) increased to $4.4 billion at December 31,
1998, from $1.4 billion in the prior year. The debt-to-total capitalization
ratio increased to 83% at year-end 1998 from 50% at year-end 1997 and 43% at the
end of 1996. The significant increase in the ratio in 1998 is from debt
financing of acquisitions. The increase in 1997 is from lower stockholders'
equity as a result of the company's stock repurchase program combined with an
increase in total debt. Over the next several years, management plans to reduce
the company's debt-to-total capitalization ratio to pre-acquisition levels. The
company has maintained investment grade rating on outstanding debt.

A quarterly dividend has been paid without interruption since 1913, the
company's first year of operation. The annual dividend of $1.08 per share during
1998 represents a total pay out for the year of $104 million. This reflects an
8% increase announced in December 1997 and payable March 25, 1998, to
shareholders of record on March 6, 1998.

Capital expenditures during 1998 were $157 million, with 27% of the expenditures
related to increased production capacity, compared with 38% in 1997 and 29% in
1996. The remainder mostly relates to cost-savings projects, capacity
maintenance, and regulatory requirements. The increase in 1998 capital
expenditures of approximately $38 million over 1997 and 1996 is primarily from
companies acquired in 1998 and higher spending in the Functional Products
segment. Capital expenditures are expected to approximate $240 million during
1999. This


                                       14
<PAGE>   15
includes funds for continuing or completing existing projects and new expansion
projects, including the methylcellulose expansion in Doel, Belgium, and the
pectin expansion in Grossenbrode, Germany.


YEAR 2000

Readiness

The company has recognized the need to ensure that its operations and
relationships with its business partners will not be adversely affected by the
Year 2000 problem, and thus has developed and implemented a comprehensive
project that addresses those areas of vulnerability. A cross-functional Year
2000 Program Office has been created by the company at the corporate level to
coordinate and provide policies, guidance, and support for its Year 2000
initiatives. Site compliance teams have been formed at all major sites
worldwide.

       The areas addressed by the Program Office include:

      --   Corporate and plant computer systems

      --   Desktop and telecommunications systems

      --   Safety, environmental and quality systems

      --   Process control systems and plant floor equipment and devices with
           embedded chips

      --   Equipment manufactured by or for the BetzDearborn Division and sold
           to customers

      --   Business partner and supply chain risk management

A risk management plan has been developed for Hercules' business partners,
including suppliers, shippers, financial institutions and service providers
involving direct communications to them and feedback analysis to assess their
Year 2000 readiness as it relates to their potential impact on Hercules'
business. Contingency plans are being developed in those cases where the company
appears to be at risk.

The company is engaged in a major project to implement SAP R/3(TM) software. All
vendor supplied SAP code is Year 2000 compliant. The resulting systems comprise
the company's core business systems, including sales and distribution, inventory
and purchasing, finance and control, product costing, human resources and
payroll, and fixed assets. Other internally developed programs are still in the
process of being tested for Year 2000 compliance. The system is in the process
of being rolled out in North America and Europe. The most critical applications
are either already operational or will be in early 1999. Overall, the project is
on schedule to be completed by third quarter 1999.

In other regions of the world, only minor changes are required to make the core
business systems Year 2000 compliant. The recently acquired BetzDearborn
Division is also in the process of implementing SAP R/3(TM) software and is on
schedule to complete its program in the second quarter of 1999 in North America.
BetzDearborn's Information Technology (IT) systems in other regions are or will
be Year 2000 compliant by second quarter 1999.

For all plants and departments, inventories have been taken of equipment that
may have an embedded chip. Assessments of the compliance status and potential
impact on company operations and remediation plans are being completed.
Additionally, suppliers of raw materials and other critical services have been
identified. Questionnaires requesting Year 2000 status have been sent to all
major identified suppliers. Identification of the most critical suppliers is in
progress and, where necessary, additional research is being conducted.
Contingency plans are being developed or alternate suppliers identified in those
cases where the company appears at risk.

The BetzDearborn Division sells chemical feed equipment installed at customer
sites. Earlier versions of this equipment were not Year 2000 compliant. A kit to
make this equipment Year 2000 compliant has been designed and tested. Affected
equipment will be updated through both regular and Year 2000 specific service
visits of the field technicians.

It is also possible that some customers may be unable to place orders or conduct
business due to their potential inability to cope with the Year 2000. Due to the
broad dispersion of sales among Hercules' customer base, there are currently no
plans to conduct any customer readiness assessments.


                                       15
<PAGE>   16

Costs
The primary strategy for achieving Year 2000 compliance is the replacement of
the core business systems through the installation of SAP R/3(TM) software. For
non-IT systems, operational staff conducted departmental inventories under the
direction of an outside consulting firm. The company is in the process of
identifying the costs associated with any necessary process control equipment
upgrades or replacements. The company has also engaged outside consultants
specializing in Year 2000 readiness programs to provide support to the program
office in the final stages of Year 2000 readiness and compliance.

The total cost of the Year 2000 project is currently estimated to be
approximately $8 million and approximately 45% has been spent to date. This cost
estimate does not include the cost to upgrade or replace process control
equipment. These costs are expensed as incurred and are being funded through
operating cash flow. The cost of implementing the SAP R/3(TM) replacement system
is not included in the Year 2000 project cost estimate.

Risks and Contingency Plans

Failure to complete implementation of the SAP system by the end of 1999 would
represent the worst case Year 2000 scenario for Hercules. At the present time,
the company believes that the implementation efforts will be completed as
scheduled so that the risks of material adverse consequences to the company's
results of operations, liquidity, or financial condition, as a result of its
Year 2000 readiness, should be reduced. Some of Hercules' production facilities
are similar in nature and products could be manufactured and shipped from
alternate locations. At these locations, there are feasible manual procedures
that can be implemented in the case of a Year 2000 related failure. For cases
where product cannot be made in multiple locations or where manual procedures
are not feasible, appropriate contingency plans are being developed and are
targeted for completion in the third quarter of 1999.

The company believes that it is unlikely to experience a material adverse effect
to its business, results of operations, liquidity, or financial condition as a
result of Year 2000 related failures.

Forward-looking Statements

The foregoing Year 2000 discussion includes forward-looking statements of the
company's efforts and management's expectations relating to Year 2000 readiness.
The company's ability to achieve Year 2000 compliance and the level of
incremental costs associated therewith could be adversely affected by, among
other things, the availability and cost of remediation and testing resources,
vendors' and customers' abilities to install or modify IT and non-IT systems and
unanticipated problems identified in the ongoing Year 2000 readiness review.

The costs of the Year 2000 project and the dates by which the company plans to
complete the Year 2000 modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third parties' remediation plans
and other factors. However, there can be no guarantee that these estimates will
be achieved and actual results could differ materially. Specific factors that
might cause such material differences include, but are not limited to, the
availability and cost of personnel trained to perform Year 2000 modifications;
the ability of the company to locate and correct all non-compliant computer
codes and embedded controls; the ability of material customers, suppliers, and
trading partners to successfully complete their own Year 2000 remediation
projects; the accuracy of information received from third parties concerning the
Year 2000 compliance of their information systems or automated equipment or
concerning their Year 2000 business risk assessments; and similar uncertainties.


CONVERSION TO THE EURO CURRENCY

On January 1, 1999, the Euro was adopted as the common legal currency, in
coexistence with the national currencies for 11 European Union member nations
until January 1, 2002. Hercules started its preparations in early 1997 with
internal Euro awareness training and the formation of a multifunctional project
team. Since then the company's Euro team has developed and implemented a
strategic action plan that positioned the company for the Euro by mid-1998.

This plan consisted of a project portfolio that was implemented in the second
half of 1998. The company has made the necessary adjustments to its IT systems
to ensure compliance of all business transactional Euro requirements and is
preparing its IT systems for the withdrawal of the national currencies by
January 1, 2002, after which the


                                       16
<PAGE>   17
Euro becomes the sole legal currency for the 11 member states. The company will
be prepared for any European Union nation that enters the Euro.

The company has communicated its strategy to deal in Euro with its business
partners in Euro-participating countries, and it will continuously reconcile its
strategy with its business partners to maintain the competitive position of the
company. The company has trained its employees and ensures compliance with all
legal and tax implications of the Euro. The company does not expect major
differences in its exchange rate and interest rate risk from the Euro.

The company does not expect the Euro adoption to have a material adverse impact
on its financial condition or results of operations.


RISK FACTORS

Market Risk - Fluctuations in interest and foreign currency exchange rates
affect the company's financial position and results of operations. The company
uses several strategies to actively hedge interest rate and foreign currency
exposure and minimize the effect of such fluctuations on reported earnings and
cash flow. (See "Foreign Currency Translation" and "Financial Instruments and
Hedging" in the Summary of Significant Accounting Policies and Notes 17 and 20.)
Sensitivity of the company's financial instruments to selected changes in market
rates and prices, which are reasonably possible over a one-year period, are
described below. Market values are the present value of projected future cash
flows based on the market rates and prices chosen. The market values for
interest rate risk are calculated by the company utilizing a third-party
software model that utilizes standard pricing models to determine the present
value of the instruments based on the market conditions as of the valuation
date.

The company's derivative and other financial instruments subject to interest
rate risk consist of debt instruments, interest rate swaps, and currency swaps.
In addition, at December 31, 1997, the company held a five-year $500 million
note received as a result of the Tastemaker transaction, which it sold during
1998. At December 31, 1998 and 1997, net market value of these combined
instruments was a liability of $3.66 billion and $239 million, respectively. The
increase is primarily the result of acquisition debt incurred during 1998. The
sensitivity analysis assumes an instantaneous 100-basis point move in interest
rates from their levels, with all other variables held constant. A 100-basis
point increase in interest rates at December 31, 1998 and 1997 would result in a
$36 million and $24 million decrease in the net market value of the liability,
respectively. A 100-basis point decrease in interest rates at December 31, 1998
and 1997 would result in a $45 million and $33 million increase in the net
market value of the liability, respectively.

The market value of the company's portfolio of financial instruments subject to
equity price risk at December 31, 1998 and 1997, was an asset of $22 million and
$51 million, respectively. The sensitivity analysis assumes an instantaneous 10%
change in valuation with all other variables held constant. A 10% change at
December 31, 1998 and 1997, would increase or decrease the asset position by $2
million and $5 million, respectively.

The company's financial instruments subject to foreign currency exchange risk
consist of foreign currency forwards and options and represent a net asset
position of $6 million and $2 million at December 31, 1998 and 1997,
respectively. The sensitivity analysis assumes an instantaneous 10% change in
foreign currency exchange rates from year-end levels, with all other variables
held constant. At December 31, 1998 and 1997, a 10% strengthening of the U.S.
dollar versus other currencies would result in an increase in the net asset
position of $63 million and $14 million, respectively, while a 10% weakening of
the dollar versus all other currencies would result in a decrease of $78 million
and $18 million, respectively.

Foreign exchange forward and option contracts are used to hedge the company's
firm and anticipated foreign currency cash flows. Thus, there is either an asset
or cash flow exposure related to all the financial instruments in the above
sensitivity analysis for which the impact of a movement in exchange rates would
be in the opposite direction and substantially equal to the impact on the
instruments in the analysis. There are presently no significant restrictions on
the remittance of funds generated by the company's operations outside the United
States.

Environmental - Hercules has been identified by U.S. federal and state
authorities as a potentially responsible party for environmental cleanup at
numerous sites. The estimated range of reasonably possible costs for


                                       17
<PAGE>   18
remediation is between $63 million and $199 million. The company does not
anticipate that its financial condition will be materially affected by
environmental remediation costs in excess of amounts accrued, although quarterly
or annual operating results could be materially affected. (See Note 22.)

Environmental remediation expenses are funded from internal sources of cash.
Such expenses are not expected to have a significant effect on the company's
ongoing liquidity. Environmental cleanup costs, including capital expenditures
for ongoing operations, are a normal, recurring part of operations and are not
significant in relation to total operating costs or cash flows.

Litigation - Hercules is a defendant in numerous lawsuits that arise out of, and
are incidental to, the conduct of its business. These suits concern issues such
as product liability, contract disputes, labor-related matters, patent
infringement, environmental proceedings, property damage, and personal injury
matters. While it is not feasible to predict the outcome of all pending suits
and claims, the ultimate resolution of these matters could have a material
effect upon the financial position of Hercules, and the resolution of any of the
matters during a specific period could have a material effect on the quarterly
or annual operating results for that period. (See Note 22.)


FORWARD-LOOKING STATEMENT

This annual report includes forward-looking statements, as defined in the
Private Securities Litigation Reform Act of 1995, reflecting management's
current analysis and expectations, based on reasonable assumptions. Results
could differ materially depending on such factors as business climate, economic
and competitive uncertainties, higher manufacturing costs, reduced level of
customer orders, ability to integrate BetzDearborn, changes in strategies, risks
in developing new products and technologies, the ability of Hercules' customers
and suppliers to achieve Year 2000 readiness, environmental and safety
regulations and clean-up costs, foreign exchange rates, adverse legal and
regulatory developments, and adverse changes in economic and political climates
around the world. Accordingly, there can be no assurance that the company will
meet analysts' earnings estimates. As appropriate, additional factors are
contained in reports filed with the Securities and Exchange Commission. This
paragraph is included to provide safe harbor for forward-looking statements,
which are not required to be publicly revised as circumstances change.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and the Board of Directors of
Hercules Incorporated
Wilmington, Delaware

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, comprehensive income, stockholders' equity
and cash flows present fairly, in all material respects, the financial position
of Hercules Incorporated and subsidiary companies at December 31, 1998 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles. In addition, in our opinion, the financial
statement schedule listed in the index appearing under Item 14(a)(2) on page
54 presents fairly, in all material respects, the information set forth therein
when read in conjunction with the related consolidated financial statements.
These financial statements and financial statement schedule are the
responsibility of the company's management; our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards that require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

As discussed in Note 23 to the financial statements, in 1997, the company
changed its method of accounting for costs incurred in connection with its
enterprise software installation.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Hercules
Incorporated and all majority-owned subsidiaries. Following the acquisition of
BetzDearborn, the company continued BetzDearborn's practice of using a November
30 fiscal year-end for all former BetzDearborn non-U.S. subsidiaries, excluding
Canada, to expedite the year-end closing process. Investments in affiliated
companies with a 20% or greater ownership interest are accounted for on an
equity basis and, accordingly, consolidated income includes Hercules' share of
their income.

USE OF ESTIMATES

Preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

ENVIRONMENTAL EXPENDITURES

Environmental expenditures that pertain to current operations or future revenues
are expensed or capitalized according to the company's capitalization policy.
Expenditures for remediation of an existing condition caused by past operations
that do not contribute to current or future revenues are expensed. Liabilities
are recognized for remedial activities when the cleanup is probable and the cost
can be reasonably estimated.

CASH AND CASH EQUIVALENTS

Cash in excess of operating requirements is invested in short-term,
income-producing instruments. Cash equivalents include commercial paper and
other securities with original maturities of 90 days or less. Book value
approximates fair value because of the short maturity of those instruments.

INVENTORIES

Inventories are stated at the lower of cost or market. Domestic inventories are
valued predominantly on the last-in, first-out (LIFO) method. Foreign and
certain domestic inventories, which in the aggregate represent 67% of total
inventories at December 31, 1998, are valued principally on the average-cost
method.

PROPERTY AND DEPRECIATION

Property, plant, and equipment are stated at cost. The company changed to the
straight-line method of depreciation, effective January 1, 1991, for newly
acquired processing facilities and equipment. Assets acquired before then
continue to be depreciated by accelerated methods. The company believes
straight-line depreciation provides a better matching of costs and revenues over
the lives of the assets. The estimated useful lives of depreciable assets are as
follows: buildings - 30 years; plant, machinery and equipment - 15 years; other
machinery and equipment - 3 to 15 years.

Maintenance, repairs, and minor renewals are charged to income; major renewals
and betterments are capitalized. Upon normal retirement or replacement, the cost
of property (less proceeds of sale or salvage) is charged to income.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill and Other intangible assets are amortized on a straight-line basis over
the estimated future periods to be benefited, generally 40 years for goodwill
and 5 to 15 years for other intangible assets.

LONG-LIVED ASSETS

The company reviews its long-lived assets, including goodwill and other
intangibles, for impairment on an exception basis whenever events or changes in
circumstances indicate carrying amounts of the assets may not be recoverable
through future cash flows. If an impairment loss has occurred based on expected
future cash flows (undiscounted), the loss is recognized in the income
statement. The amount of the impairment loss is the excess of the carrying
amount of the impaired asset over the fair value of the asset. The fair value
represents expected future cash flows from the use of the assets, discounted at
the rate used to evaluate potential investments.

FOREIGN CURRENCY TRANSLATION

With the exception of operations in countries with highly inflationary
economies, the financial statements of Hercules' non-U.S. entities are
translated into U.S. dollars using current rates of exchange, with gains or
losses included in the foreign currency translation adjustment account in the
stockholders' equity section of the balance sheet. The related allocation for
income taxes is not significant. For operations in countries with highly
inflationary economies, financial statements are translated at either current or
historical exchange rates, as appropriate. These adjustments, along with gains
and losses on currency transactions (denominated in currencies other than local
currency), are reflected in net income.

FINANCIAL INSTRUMENTS AND HEDGING

Derivative financial instruments are used to hedge risk caused by fluctuating
currency and interest rates. The company enters into forward-exchange contracts
and currency swaps to hedge foreign currency exposure. Decisions regarding
hedging are made on a case-by-case basis, taking into consideration the amount
and duration of the exposure, market volatility, and economic trends. The
company uses the fair-value method of accounting, recording realized and
unrealized gains and losses on these contracts quarterly. They are included in
other income (expense), net, except for gains and losses on contracts to hedge
specific foreign currency commitments, which are deferred and accounted for as
part of the transaction. Gains or losses on contracts used to hedge the value of
investments in certain non-U.S. subsidiaries are accounted for under the
deferral method and are included in the foreign currency translation adjustment
account. It is the company's policy to match the term of financial instruments
with the term of the underlying designated item. If the designated item is an
anticipated transaction no longer likely to occur, gains or losses from the
instrument designated as a hedge are recognized in current period earnings. The
company does not hold or issue financial instruments for trading purposes. In
the Consolidated Statement of Cash Flow, the company reports the cash flows
resulting from its hedging activities in the same category as the related item
that is being hedged. Net investment hedges, requiring cash receipts or payments
from borrowed foreign currencies not identified with any specific cash flows,
are classified as financing activities.

The company uses interest rate swap agreements to manage interest costs and
risks associated with changing rates. The differential to be paid or received is
accrued as interest rates change and is recognized in interest expense over the
life of the agreements. Counterparties to the forward exchange, currency swap,
and interest rate swap contracts are major financial institutions. Credit loss
from counterparty nonperformance is not anticipated.

STOCK-BASED COMPENSATION

Compensation costs attributable to stock option and similar plans are recognized
based on any difference between the quoted market price of the stock on the date
of grant over the amount the employee is required to pay to acquire the stock
(the intrinsic-value method under Accounting Principles Board [APB] Opinion 25).
Such amount, if any, is accrued over the related vesting period, as appropriate.
Statement of Financial Accounting Standard (SFAS) No. 123, "Accounting for
Stock-Based Compensation," requires companies electing to continue to use the
intrinsic-value method to make pro forma disclosures of net income and earnings
per share as if the fair-value-based method of accounting had been applied.

NEW ACCOUNTING STANDARDS

Effective January 1, 1998, the company adopted SFAS, No. 130, "Reporting
Comprehensive Income." SFAS 130 establishes standards for reporting and display
of comprehensive income and its components in financial statements. This
statement requires all items that are required to be recognized under accounting
standards as components of comprehensive income be reported in the financial
statements and displayed with the same prominence as other financial statements.
In 1998, the company adopted SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information." (See Note 24).

PENDING ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS 133 is
effective for fiscal years beginning after June 15, 1999. SFAS 133 requires that
all derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives are recorded each period in current
earnings or other comprehensive income, depending on whether a derivative is
designated as part of a hedge transaction. For fair-value hedge transactions in
which the company is hedging changes in the fair value of an asset, liability,
or firm commitment, changes in the fair value of the derivative instrument will
generally be offset in the income statement by changes in the hedged item's fair
value. For cash-flow hedge transactions, in which the company is hedging the
variability of cash flows related to a variable-rate asset, liability, or a
forecasted transaction, changes in the fair value of the derivative instrument


                                       27
<PAGE>   28
will be reported in other comprehensive income. Gains and losses on the
derivative instrument that are reported in other comprehensive income will be
reclassified as earnings in periods in which earnings are impacted by the
variability of the cash flows of the hedged item. The ineffective portion of all
hedges will be recognized in current-period earnings.

In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" (SOP 98-1). SOP 98-1 provides guidance
on the capitalization and amortization of costs of computer software developed
or obtained for internal use, and is effective for fiscal years beginning after
December 15, 1998. The company is currently capitalizing the design and
implementation costs of its ongoing enterprise-wide software installation
program.

The company is currently evaluating the impact that these statements will have
on its results of operations or financial position.

RECLASSIFICATIONS

Certain amounts in the 1997 and 1996 consolidated financial statements and notes
have been reclassified to conform to the 1998 presentation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.    ACQUISITIONS

All acquisitions have been accounted for under the purchase method. The results
of operations of the acquired businesses are included in the consolidated
financial statements from the dates of acquisition.

BetzDearborn - On October 15, 1998, the company acquired all of the outstanding
shares of BetzDearborn Inc., a global specialty chemical company engaged in the
treatment of water and industrial process systems, for $2,235 million in cash
and $186 million in common stock exchanged for the shares held by the
BetzDearborn ESOP Trust. In addition, the company assumed debt with a fair value
of $117 million and repaid $557 million of other long-term debt held by
BetzDearborn. This acquisition was financed with borrowings under a $3,650
million credit facility with a syndicate of banks. (See Note 6.)

The purchase price was allocated to the estimated fair value of net assets
acquired, with the excess of $2,074 million recorded as goodwill, which is being
amortized over its estimated useful life of 40 years. Additionally, based on an
independent appraisal, approximately $130 million of the purchase price was
allocated to purchased in-process research and development and was charged to
expense at the date of acquisition. (See Note 14.)

As of the acquisition date, the company began to formulate plans to combine the
operations of BetzDearborn and Hercules. It formed a program office, engaged
outside consultants and established several functional integration teams to
formulate and implement the plan and capture anticipated synergies. At December
31, 1998, the company had identified and approved various actions such as
personnel reductions, consolidation of operations and support functions, closure
of redundant or inefficient offices and facilities, and relocation of former
BetzDearborn employees. Accordingly, the company has included a $94 million
liability as part of the purchase price allocation. The liability includes
approximately $78 million related to employee termination benefits for
approximately 850 BetzDearborn manufacturing, technical, sales and marketing,
administrative and support personnel worldwide. Also included is $16 million for
office and facility closures, relocation of BetzDearborn employees and other
related exit costs. Through December 31, 1998, the company paid $5 million of
termination benefits for approximately 130 redundancies, and the remaining
liability is $89 million.

The purchase price allocation for BetzDearborn is a preliminary allocation and
the goodwill recorded is subject to further adjustment resulting primarily from
the completion of the integration and exit plans, which could result in
additional liabilities; adjustments to the fair value of the net assets
acquired; and the resolution of pre-acquisition contingencies, primarily legal
matters and product liabilities, net of any related tax effects.
The allocation of the purchase price is expected to be completed in 1999.

FiberVisions L.L.C. - In July 1998, the company completed the acquisition of the
49% share of FiberVisions L.L.C. owned by its joint venture partner Jacob Holm &
Sons A/S for approximately $230 million in cash, plus assumed debt of $188
million. The allocation of the purchase price resulted in $188 million of
goodwill, which is being amortized over its estimated useful life of 40 years.

The pro forma results of operations are for comparative purposes only and
reflect increased amortization and interest expense resulting from the
acquisitions described above, but do not include any potential cost savings from
combining the acquired businesses with the company's operations. Consequently,
the pro forma results do not reflect the actual results of operations had the
acquisitions occurred on the dates indicated, and are not intended to be a
projection of future results or trends.

Other - The company also made three other acquisitions in 1998 for an aggregate
purchase price of approximately $105 million in cash. These acquisitions
included the worldwide paper chemicals group of Houghton International, Inc. and
Citrus Colloids Ltd., a pectin manufacturer, in April 1998, and Alliance
Technical Products, Ltd., a rosin dispersions company, in September 1998.
Allocations of the purchase prices for these acquisitions resulted in
approximately $67 million of goodwill, which is being amortized over estimated
useful lives ranging from 30 to 40 years.

4.    INVESTMENTS

Total equity investments in affiliated companies were $9 million at December 31,
1998, and $21 million at December 31, 1997. Dividends received from affiliated
companies were $0 in 1998 and 1997, and $11 million in 1996.

Other investments, at cost or less, were $42 million and $594 million at
December 31, 1998 and 1997, respectively. Included in these amounts are
non-current marketable securities aggregating $31 million and $81 million for
the corresponding years, classified as "available for sale." The value of these
investments, based on market quotes, approximates book values. At December 31,
1997, investments also included a $500 million 6.2% interest-bearing five-year
note (the Tastemaker note), which was sold in October 1998 for a $3 million net
loss as part of financing the BetzDearborn acquisition.

The commercial paper program was replaced by the debt syndication utilized for
the acquisition of BetzDearborn. Previously, commercial paper was issued or
renewed for varying periods, with interest at prevailing market rates. Bank
borrowings represent primarily foreign overdraft facilities and short-term lines
of credit, which are generally payable on demand with interest at various rates.
Book values of commercial paper and bank borrowings approximate market value
because of their short maturity period.

At December 31, 1998, Hercules had $219 million of unused lines of credit that
may be drawn as needed, with interest at a negotiated spread over lenders' cost
of funds. Lines of credit in use at December 31, 1998, were $80 million.
Weighted-average interest rates on short-term borrowings at December 31, 1998
and 1997, were 5.10% and 5.40%, respectively.

       (a) 30-year debentures with a 10-year put option, exercisable by
bondholder at a redemption price equal to principal amount.

       (b) Par value of $125 million issued June 1993.

       (c) Subordinated debentures are convertible into common stock at $14.90
per share and are redeemable at the option of the company at varying rates. The
annual sinking fund requirement of $5 million, beginning in 1996, has been
satisfied through conversions of debentures.

       (d) The BetzDearborn acquisition was financed with borrowings under a
$3,650 million credit facility with a syndicate of banks, and was consummated on
October 15, 1998. The syndication included three tranches of varying maturity
term loans totaling $2,750 million and a $900 million revolving credit
agreement. The facility bears interest at London Interbank Offered Rate (LIBOR)
plus 2% and may decrease to LIBOR plus .75% after six months and after certain
conditions are met, including repayments of term-loan tranche B. Interest rates
are reset for one, three or six-month periods at the company's option. The
company's debt agreement contains various restrictive covenants that, among
other things, require maintenance of certain financial covenants: leverage, net
worth and interest coverage, and provides that the entry of a judgment or
judgments involving aggregate liabilities of $50 million or more be vacated,
discharged, stayed or bonded pending appeal within 60 days of entry. Issuance
costs of $59 million related to the financing are included in Deferred charges
and other assets and are being amortized over the term of the loans, using the
effective interest method. As of December 31, 1998, $612 million of the $900
million revolver is available for use.

       (e) The company assumed a loan with a fair market value of $110 million
related to the BetzDearborn ESOP Trust. The proceeds of the loan were used by
the ESOP Trust for the purchase of BetzDearborn preferred shares which, upon
acquisition by Hercules, were converted into equivalent shares of Hercules
common stock. The loan was recorded at fair market value at the date of
acquisition, and the $16 million fair value step-up is being amortized over the
term of the debt. The loan and guarantee mature in June 2009.

       (f) Debt assumed in conjunction with the acquisition of FiberVisions
L.L.C. (see Note 1), less repayments through December 31, 1998.

Long-term debt maturities during the next five years are $486 million in 1999,
$1,342 million in 2000, $318 million in 2001, $366 million in 2002, and $831
million in 2003.

7.    COMPANY-OBLIGATED PREFERRED SECURITIES OF SUBSIDIARY TRUST

In the fourth quarter of 1998, Hercules Trust V (the Trust), the company's
wholly owned consolidated subsidiary trust created under the laws of the State
of Delaware, completed a private placement of units, consisting of Trust
Preferred Securities (the Securities) in the amount of $200 million and a
forward underwriting contract to purchase Hercules common stock. The proceeds of
the Securities were invested by the Trust in the company's newly issued Junior
Subordinated Debenture Notes (the Notes). Each Security will accrue and pay
distributions equal to LIBOR plus 175 basis points, compounded quarterly. The
obligations of the Trust are fully and unconditionally guaranteed by the
company.

The Securities are expected to be remarketed pursuant to their terms within 12
months from their issuance. The distribution rates will be reset to a fixed rate
in the remarketing based on bids received in a private auction to qualified
institutional buyers, and the maturity date will be reset to the one-year
anniversary of the successful remarketing. Hercules will be required to redeem
the Securities if remarketing does not occur within the established period. The
remarketing of the Securities may be accelerated under certain circumstances,
including the price of the company's common stock closing at or below $22.6875
(twenty-two and eleven-sixteenths). In addition, Hercules has agreed to offer
and sell, and a third party has agreed to underwrite $200 million of Hercules
common stock following the successful remarketing or redemption of the
Securities.

8.    SERIES PREFERRED STOCK

The series preferred stock is without par value and is issuable in series. There
are 2,000,000 shares authorized for issuance, none of which have been issued.

9.    COMMON STOCK

Hercules common stock has a stated value of $25/48, and 300,000,000 shares are
authorized for issuance. At December 31, 1998, a total of 16,023,661 shares were
reserved for issuance for the following purposes: 879,999 shares for sales to
the Savings Plan Trustee; 11,382,530 shares for the exercise of awards under the
Stock Option Plan; 2,197,137 shares for awards under incentive compensation
plans; 337,440 shares for conversion of debentures and notes; and 1,226,555
shares for employee stock purchases.


                                       32
<PAGE>   33
For the company's stock repurchase program, from its start in 1991 through
year-end 1998, the Board authorized the repurchase of up to 74,650,000 shares of
company common stock. Of that total, 6,150,000 shares were intended to satisfy
requirements of various employee benefit programs. During this period, a total
of 66,490,592 shares of common stock were purchased in the open market at an
average price of $37.33 per share.

10.    EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

In connection with the acquisition of BetzDearborn, the company acquired its
ESOP and related trust as a long-term benefit for substantially all of
BetzDearborn's U.S. employees. The plan is a supplement to the company's
retirement plan. The ESOP trust has existing long-term debt of $94 million (fair
value of $110 million - see Note 6) which is guaranteed by the company. The
proceeds of the original loan were used to purchase BetzDearborn convertible
preferred stock, which, at the date of the BetzDearborn acquisition, was
converted into Hercules common stock.

The BetzDearborn 401(k) program was previously integrated with the ESOP.
Eligible employees may invest 2% to 15% of eligible compensation. The company's
matching contributions equal to 50% of the first 6% of employees' investments,
fully vest to employees upon the completion of 5 years of service. The company's
matching contributions, which are made in the form of Hercules common stock, are
included in ESOP expense. After satisfying the 401(k) matching contributions and
the dividends on allocated shares, the remaining shares of ESOP stock are
allocated to each participant based on the ratio of participants' compensation
to total compensation of all participants.

The company contribution and dividends on the shares held by the ESOP trust are
used to repay the loan, and stock is allocated as the principal and interest are
paid. Long-term debt is reduced as payments are made on the third-party
financing. The loan and unearned compensation are recorded in the company's
Consolidated Balance Sheet as long-term debt and a reduction in shareholders'
equity, respectively.

The number of shares allocated and unallocated at December 31 are as follows:

The company is required to make cash contributions to the Plan which enable the
trust to service its indebtedness. ESOP expense was $1 million for 1998 which
was net of $2 million of dividends paid and charged to retained earnings.

11.    LONG-TERM INCENTIVE COMPENSATION PLANS

The company's long-term incentive compensation plans provide for the grant of
stock options and the award of common stock and other market-based units to
certain key employees and nonemployee directors. Through 1994, shares of common
stock awarded under these plans normally were either restricted stock or
performance shares. During the restriction period, award holders have the rights
of stockholders, including the right to vote and receive cash dividends, but
they cannot transfer ownership.

In 1995, Hercules changed the structure of the long-term incentive compensation
plans to place a greater emphasis on shareholder value creation through grants
of regular stock options, performance-accelerated stock options, and Cash Value
Awards (performance-based awards denominated in cash and payable in shares of
common or restricted stock, subject to the same restrictions as restricted
stock). Restricted stock and other market-based units are awarded with respect
to certain programs. The number of awarded shares outstanding was 1,083,613;
873,627; and 1,881,946 at December 31, 1998, 1997, and 1996, respectively.

Under the company's incentive compensation plans, 2,197,137 shares of common
stock were available for grant as stock awards or stock option awards. Stock
awards are limited to approximately 15% of the total authorizations. Regular
stock options are granted at the market price on the date of grant and are
exercisable at various periods from one to five years after date of grant.
Performance-accelerated stock options are also granted at the market price on
the date of grant and are normally exercisable at nine and one-half years.
Exercisability may be


                                       33
<PAGE>   34
accelerated based upon the achievement of predetermined performance goals. Both
regular and performance-accelerated stock options expire 10 years after the date
of grant.

Restricted shares, options and performance-accelerated stock options are
forfeited and revert to the company in the event of employment termination,
except in the case of death, disability, retirement, or other specified events.

The company applies APB Opinion 25 in accounting for its plans. Accordingly, no
compensation cost has been recognized for the stock option plans. The cost of
stock awards and other market-based units, which are charged to income over the
restriction or performance period, amounted to $5 million for 1998; $4 million
for 1997, and $9 million for 1996.

Below is a summary of outstanding stock option grants under the incentive
compensation plans during 1996, 1997, and 1998:

The company estimates at December 31, 1998, 100% of performance-accelerated
stock options will eventually vest.

The company's Employee Stock Purchase Plan is a qualified noncompensatory plan,
which allows eligible employees to acquire shares of common stock through
systematic payroll deductions. The plan consists of three-month subscription
periods, beginning July 1 of each year. The purchase price is 85% of the fair
market value of the common stock on either the first or last day of that
subscription period, whichever is lower. Purchases may range from 2% to 15% of
an employee's base salary each pay period, subject to certain limitations.
Currently, 1,226,555 shares of Hercules common stock are registered for offer
and sale under the plan. Shares issued at December 31, 1998 and 1997, were
573,445 and 468,706, respectively. The company applies APB Opinion 25 and
related interpretations in accounting for its Employee Stock Purchase Plan.
Accordingly, no compensation cost has been recognized for the Employee Stock
Purchase Plan.

Had compensation cost for the company's Stock-Based Incentive Plans and Employee
Stock Purchase Plan been determined on the basis of fair value according to SFAS
No. 123, the fair value of each option granted or share purchased would be
estimated on the grant date using the Black-Scholes option pricing model.

The following assumptions would be used in estimating fair value for 1998, 1997,
and 1996:

Pension

During 1997, the company recognized a charge of approximately $8 million for
special termination benefits.

Other Postretirement Benefits

The non-pension postretirement benefit plans are contributory health care and
life insurance plans. In August 1993, a Voluntary Employees' Beneficiary
Association (VEBA) Trust was established and funded with $10 million of company
funds. The company periodically obtains reimbursement for union retiree claims,
while other claims are paid from company assets. The participant contributions
are immediately used to cover claim payments, and for this reason do not appear
as contributions to plan assets.

The assumed health care cost trend rate at December 31, 1998 and 1997, was 5%
for those under age 65 and 4.75% for those over age 65, decreasing to 4.5% in
subsequent years.

A one-percentage point increase or decrease in the assumed health care cost
trend rate would increase or decrease the postretirement benefit obligation by
$6 million or $7 million, respectively, and would not have a material effect on
aggregate service and interest cost components.

14.    PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT

Purchased in-process research and development (IPR&D) represents the value
assigned in a purchase business combination to research and development projects
of the acquired business that were commenced but not yet completed at the date
of the acquisition, and which, if unsuccessful, have no alternative future use
in research and development activities or otherwise. Amounts assigned to
purchased IPR&D must be charged to expense at the date of consummation of the
purchase business combination. Accordingly, the company has charged
approximately $130 million to expense at the acquisition date for IPR&D related
to the BetzDearborn acquisition. (See Note 1.)

The IPR&D projects were principally included in the water treatment and paper
process divisions of the acquired business. The former Water Treatment Group
(WTG) provided specialty water and process treatment programs for boiler,
cooling, influent, and effluent applications to markets such as refining,
chemical, paper, electric utility, food, industrial, commercial and
institutional establishments. Overall, the products are used to control
corrosion, scale, deposit formation, and microbiological growth, conserve energy
and improve efficiency. Additionally, the former Paper Process Group (PPG)
brought to market custom-engineered programs for the process-related problems
associated with paper production. These problems include deposition, corrosion,
microbiological fouling, foam control, deinking and felt conditioning.

1)     This project will continuously screen new microbiocidal actives in order
       to identify promising compounds that may improve current product mix of
       offerings.

2)     This project involves the development of new corrosion control chemistry
       for application in a range of water treatment systems.

3)     This project involves the development of advanced retention, drainage,
       and formation systems for printing and writing paper.

Due to the uniqueness of each of the projects, the costs and effort required are
estimated based on the latest available information. Additionally, the launch
date reflects management's best estimate of the time that the company will begin
to benefit from cash inflow of the projects. However, there is a risk that
certain projects may not be completed successfully for a variety of reasons
including: change in strategies, inability to develop a cost efficient
treatment, and changes in market demand or customer requirements.

The IPR&D valuation charge was measured by the stage of completion method,
primarily calculated by dividing the costs incurred to date by the total
estimated costs. These percentages were applied to the results of
project-by-project discounted cash flow models that estimated the present value
of residual cash flows deemed attributable solely to the underlying IPR&D.

The projected revenues, costs, and margins in the cash flow forecasts are
consistent with projections by management based on available historical data.
The revenue projections are based on an opportunity analysis for each project,
which takes into account market and competitive conditions, potential customers,
and strategic goals. The weighted average cost of capital for the overall
business was estimated at 11% and the risk-adjusted discount rate used in the
IPR&D project valuation model was 13%.

15.    OTHER OPERATING EXPENSES (INCOME), NET

As a result of the BetzDearborn acquisition in the fourth quarter of 1998,
Hercules began to formulate and implement a plan to merge the operations of
BetzDearborn with Hercules (see Note 1). Additionally, the company reviewed its
existing operations and support infrastructure and approved a plan to terminate
Hercules employees and exit activities to eliminate redundancies and
inefficiencies. As a result, the company incurred charges of approximately $76
million. These charges include employee termination benefits of $31 million;
exit costs related to facility closures of $10 million; write-downs of property,
plant and equipment of $24 million; and integration expenses of $11 million.
Employee termination benefits are for approximately 350 Hercules manufacturing,

and marketing, administration, technology and support personnel. Facility
closures and exit costs relate primarily to Process Chemicals and Services in
connection with the acquisition. Write-downs of property, plant and equipment
relate to asset impairments in Chemical Specialties and Functional Products
resulting from adverse business negotiations, the effects of the BetzDearborn
acquisition, and the loss of a customer. Integration expenses include consulting
and legal fees, integration bonuses, travel and training, and are expensed as
incurred.

Other operating expenses in 1997 included charges of $146 million, primarily
associated with reorganization of management and the adoption of new competitive
strategies (announced in early 1997). The charges included $122 million related
to asset rationalizations and impairment and $24 million related to severance
benefits. Included in the $122 million is an impairment loss of $95 million.
Additionally, the company recognized approximately $27 million of
rationalization charges primarily associated with certain assets, which were no
longer being utilized, and lease abandonment costs. Concurrently, management
authorized and committed the company to a plan to reduce its work force by
approximately 270 employees and accrued $24 million of severance-related
benefits. The plan included reorganization of management, reductions in
operating personnel at certain domestic and foreign facilities, and the
consolidation of certain support functions. Other operating expenses in 1997
also include $13 million of net environmental cleanup costs, principally for
nonoperating sites and $8 million of executive retirement benefits.

In 1996, other operating expenses (income), net, included probable recoveries
related to environmental remediation of $13 million and reduction in the
estimated loss on the divestiture of the Composite Products Division of $5
million.

During 1998, the company paid $10 million of these liabilities. As of December
31, 1998, the remaining liability for these charges is $36 million for
termination benefits representing approximately 370 employees and $10 million
for other exit costs. Reorganization in the foreign facilities has proceeded
slower than anticipated due to changes in the information system implementation
schedule, acquisition activity and other corporate initiatives. Management
expects to complete remaining actions under this plan during 2000.

</TABLE>

Interest income in 1998 and 1997 relates primarily to the $500 million note
received upon completion of the Tastemaker monetization. The note was sold
during the fourth quarter of 1998 with a net loss of $3 million reported in net
gains on dispositions. Also, gains of $12 million and $19 million in 1998 and
1997, respectively, were recorded from the sale of Alliant Techsystems common
stock held by Hercules. (See Note 21.) Additionally, 1997 includes a gain of
$368 million on the completion of transactions that monetized the company's
investment in Tastemaker, a 50%-owned flavors joint venture. Net gains on
dispositions in 1996 reflect the sale of real estate and the sale of a product
line. Acquisition costs in 1997 represent a charge primarily related to the
company's

unsuccessful bid for Allied Colloids. The 1998 legal settlements and
accruals relate primarily to settlements of Qui Tam ("Whistle Blower") lawsuits.
(See Note 22.) The 1998 loss from terminated interest rate swaps is related to
the company's financing effort upon the acquisition of BetzDearborn.
Miscellaneous income (expense), net, includes net foreign currency gains of $5
million, $19 million, and $11 million in 1998, 1997, and 1996, respectively.

The company provides taxes on undistributed earnings of subsidiaries and
affiliates included in consolidated retained earnings to the extent such
earnings are planned to be remitted and not reinvested permanently.

The undistributed earnings of subsidiaries and affiliates on which no provision
for foreign withholding or U.S. income taxes has been made amounted to
approximately $400 million at December 31, 1998. U.S. and foreign income taxes
that would be payable if such earnings were distributed may be lower than the
amount computed at the U.S. statutory rate because of the availability of tax
credits.

20.      FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

Notional Amounts and Credit Exposure of Derivatives

The notional amounts of derivatives summarized below do not represent 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, which
relate to interest rates or exchange rates.

Interest Rate Risk Management

During 1998, interest rate swaps which converted 6.02% average fixed-rate debt
to floating-rate debt expired. During the fourth quarter, a series of interest
rate swap agreements converting floating rate debt into fixed rate debt ranging
from 6.05% to 7.08% per year were terminated primarily in conjunction with the
sale of the Tastemaker note (see Note 4) and the BetzDearborn acquisition. New
interest rate swaps totaling $1.0 billion were added in the fourth quarter 1998.
This series of interest rate swap agreements, maturing from 1999 through
December 2002, effectively converts floating-rate debt into debt with a fixed
rate ranging from 4.91% to 5.21% per year as a hedge against the company's
interest rate exposure on its variable rate debt outstanding. For the years
1998, 1997, and 1996, these contracts resulted in a less than 1% change in the
effective interest rate on the weighted-average notional principal amounts
outstanding. The aggregate notional principal amounts at the end of 1998 and
1997 were $1.0 billion and $650 million, respectively.

The following table indicates the types of swaps used and their weighted-average
interest rates:

</TABLE>

Foreign Exchange Risk Management

The company selectively uses foreign currency forward contracts and currency
swaps to offset the effects of exchange rate changes on reported earnings, cash
flow, and net asset positions. The primary exposures are denominated in Danish
kroner, Dutch guilder, Belgian franc, British pound sterling, and the German
mark. Some of the contracts involve the exchange of two foreign currencies,
according to local needs in foreign subsidiaries. The term of the currency
derivatives is rarely more than one year. At December 31, 1998 and 1997, the
company had outstanding forward-exchange contracts to purchase foreign
currencies aggregating $117 million and $29 million and to sell foreign
currencies aggregating $320 million and $171 million, respectively. Non-U.S.
dollar cross-currency trades aggregated $380 million and $630 million at
December 31, 1998 and 1997, respectively. Currency swap agreements, used to
hedge net investment positions, totaled $512 million at December 31, 1998. The
forward-exchange contracts and currency swap agreements outstanding at December
31, 1998 will mature during 1999.

21.     DIVESTITURES

In March 1997, the company completed transactions to monetize its investment in
Tastemaker for approximately $608 million, including $108 million in cash and a
$500 million, 6.2%, interest-bearing five-year note. Equity in income of
affiliated companies included Tastemaker earnings of $11 million in 1997 and $32
million in 1996.

In June 1997, the company completed a joint venture of its polypropylene fiber
business with Jacob Holm & Sons A/S (Denmark) in which Hercules owned 51% of the
joint venture, which was accounted for on the equity method at that time. In
July 1998, Hercules purchased its partner's 49% share of the joint venture, with
the operating results of FiberVisions being included in Hercules' consolidated
financial statements since the date of acquisition. (See Note 1.)

Pursuant to a 1997 agreement, Hercules sold its remaining shares of Alliant
Techsystems Inc. for $12 million in 1998.

In June 1996, the company sold its Composite Products Division for $141 million
in cash. Net sales and operating profit of this business were $49 million and $8
million, respectively in 1996.

22.     COMMITMENTS AND CONTINGENCIES

Leases

Hercules has operating leases (including office space, transportation, and data
processing equipment) expiring at various dates. Rental expense was $35 million
in 1998, and $31 million in both 1997 and 1996.

At December 31, 1998, minimum rental payments under noncancelable leases
aggregated $317 million with subleases of $30 million. A significant portion of
these payments relates to a long-term operating lease for corporate office
facilities. The net minimum payments over the next five years are $39 million in
1999, $32 million in 2000, $24 million in 2001, $20 million in 2002, and $18
million in 2003.

Environmental

Hercules has been identified as a potentially responsible party (PRP) by U.S.
federal and state authorities, or has been sued for contribution by private
parties, for the cost of environmental investigation and/or cleanup at numerous
sites. The estimated range of the reasonably possible share of costs for
investigation and cleanup is between $63 million and $199 million. The actual
costs will depend upon numerous factors, including the number of parties found
responsible at each environmental site and their ability to pay, the actual
methods of remediation, outcomes of negotiations with regulatory authorities,
outcomes of litigation, changes in environmental laws and regulations,
technological developments, and the years of remedial activity required, which
could range up to 30 years.

In 1992, Hercules brought suit against its insurance carriers for past and
future costs for cleanup of certain environmental sites. In April 1998, the
trial regarding insurance recovery for the Jacksonville, Arkansas site (see
discussion below) was completed. The jury returned a "Special Verdict Form" with
findings that will, in conjunction with the court's other opinions, be used by
the Court to enter a judgment. The judgment will determine the amount of
Hercules recovery for past cleanup expenditures and will state that Hercules is
entitled to similar coverage for costs incurred since September 30, 1997 and in
the future. Hercules has not included any insurance recovery in the estimates
above.

Hercules becomes aware of sites in which it may be, but has not yet been named a
PRP, principally through its knowledge of investigation of sites by the U.S.
Environmental Protection Agency (EPA) or other government agencies or through
correspondence with previously named PRPs requesting information on Hercules'
activities at sites under investigation. In addition, Hercules has established
procedures for identifying environmental issues at its respective plant sites.
Environmental coordinators, familiar with environmental laws and regulations,
are resources for identification of environmental issues. Further, Hercules has
environmental audit programs, which are designed to identify environmental
issues at operating plant sites. Through these programs and
information-gathering activities, Hercules identifies potential environmental,
regulatory, and remedial issues.

Litigation over liability at Jacksonville, Arkansas, the most significant site,
has been pending since 1980. As a result of a pretrial court ruling in October
1993, Hercules has been held jointly and severally liable for costs incurred,
and for future remediation costs, at the Jacksonville site by the District
Court, Eastern District of Arkansas (the Court).

Other defendants in this litigation have either settled with the government or,
in the case of the Department of Defense (DOD), have not been held liable.
Hercules appealed the Court's order finding the DOD not liable. On January 31,
1995, the 8th Circuit Court of Appeals upheld the Court's order. Hercules filed
a petition to the U.S. Supreme Court requesting review and reversal of the 8th
Circuit Court ruling. This petition was denied on June 26, 1995, and the case
was remanded to the District Court for further proceedings.

On May 21, 1997, the Court issued a ruling that Uniroyal is liable and that
Standard Chlorine is not liable to Hercules for contribution. A trial on
allocation and damages among Hercules, Uniroyal, and the United States was
scheduled to begin October 1998. Through the filing of separate summary judgment
motions, Hercules and Uniroyal raised a number of defenses to the United States'
ability to recover its costs. On October 23, 1998, the Court denied those
motions and granted the United States' summary judgment motion, ordering
Hercules and Uniroyal to pay the United States approximately $103 million plus
any additional response costs incurred or to be incurred after July 31, 1997.
Hercules expects that this amount will be reduced by approximately $7 million,
the amount received by the United States in previous settlements with other
parties. Trial testimony on the issue of allocation between Hercules and
Uniroyal was completed on November 6, 1998. Once a final judgment has been
entered, Hercules expects to appeal the Court's determination with respect to
its liability, the United States' costs, the divisibility of harm issue, and
Standard Chlorine's liability.

At December 31, 1998, the accrued liability for environmental remediation
represents management's best estimate of the probable and reasonably estimable
costs related to environmental remediation. The extent of liability is evaluated
quarterly. The measurement of the liability is evaluated based on currently
available information, including the process of remedial investigations at each
site and the current status of negotiations with regulatory authorities
regarding the method and extent of apportionment of costs among other PRPs.
Hercules does not anticipate that its financial condition will be materially
affected by environmental remediation costs in excess of amounts accrued,
although quarterly or annual operating results could be materially affected.

Litigation:

The company is a defendant in numerous lawsuits that arise out of, and are
incidental to, the conduct of its business. In these legal proceedings, no
specifically identified director, officer, or affiliate is a party or a named
defendant. These suits concern issues such as product liability, contract
disputes, labor-related matters, patent infringement, environmental proceedings,
property damage, and personal injury matters.

Hercules was a defendant in three Qui Tam (Whistle Blower) lawsuits brought by
former employees of the Aerospace business sold to Alliant Techsystems Inc. in
March 1995. Among the allegations made in the three lawsuits were allegations
relating to submission of false claims and records under various government
contracts, delivery of defective products, a deficient quality control program,
mischarging of work performed under government contracts, misuse of government
equipment, other acts of financial mismanagement, and wrongful termination
claims. The government, after investigation of the allegations, declined to
intervene in two of these lawsuits and partially intervened in the third. In May
1998, Hercules announced that it had agreed to settle the first lawsuit. The
settlement was approved by the court and the case was dismissed in July 1998.

In August 1998, the parties to the second lawsuit reached a tentative
settlement, subject to approval of the court. Although it did not intervene in
the case, the U.S. Department of Justice (DOJ) objected to approval of the
tentative


                                       45
<PAGE>   46
settlement, arguing that Hercules should only be released from claims that the
government contended were actually investigated, and that the proposed
allocation of settlement proceeds between False Claims Act claims and wrongful
termination claims should be revised to attribute a higher percentage of
recovery to claims arising under the False Claims Act. On February 9, 1999, the
court entered a judgment approving the settlement and dismissing the lawsuit.
The DOJ has 60 days from that date in which to file a Notice of Appeal, if it
chooses to do so.

In February 1998, the parties to the third lawsuit reached a tentative
settlement, which has since been finalized, under which all claims alleging
mischarging to the Intermediate Nuclear Forces Contract were settled. Other
portions of the complaint were not resolved by the settlement. In August 1998,
the parties reached a tentative settlement of the remaining portions of the
complaint, subject to approval of the Court. The DOJ objected to approval of the
tentative settlement, arguing that Hercules should only be released from claims
that the government contended were actually investigated, and that the
settlement agreement should have contained certain provisions preventing Alliant
Techsystems Inc., which was also a defendant in the lawsuit, from recovering
certain costs under its government contracts. On February 17, 1999, the Court
entered a judgment approving the settlement and dismissing the lawsuit. The DOJ
has 60 days from that date in which to file a Notice of Appeal, if it chooses to
do so.

As a result of these settlements, the company recognized charges of $4 million
and $62 million in 1997 and 1998, respectively.

In addition to the Jacksonville, Arkansas, site litigation described above, two
individuals have sued Hercules in a lawsuit captioned Jeffrey Shelton, Jr., et
al. v. Hercules Incorporated, Civil No. LR-C-97-131 (E.D. Ark. 1997). These
individuals seek medical monitoring and damages for loss of recreational
opportunities. They have brought a Resource Conservation and Recovery Act (RCRA)
citizens suit against Hercules seeking an injunction which would require
Hercules to fund or perform various environmental and health studies and pay for
any required remediation to the Bayou Meto. Trial is presently scheduled for
August 1999. Further, 19 individuals have sued Hercules in a matter entitled
Gary Graham, et al. v. Vertac Chemical Corporation and Hercules Incorporated,
No. LR-C-98-678 (E.D. Ark. 1998). These individuals seek damages for personal
injuries and diminution of property value as a result of alleged dioxin
contamination from the Jacksonville site. Trial is presently scheduled for
August 1999. Hercules denies liability in both actions, and Hercules intends to
vigorously defend itself.

BetzDearborn, along with Pacific Gas and Electric (PG&E), is a defendant in four
lawsuits involving in the aggregate approximately 2,350 plaintiffs pending in
the Superior Court of Los Angeles County, California (the Lawsuits). Plaintiffs
are comprised primarily of present and former PG&E employees, their families,
and residents living in the vicinity of the three PG&E facilities that are the
subject of the Lawsuits. Plaintiffs seek unspecified monetary damages (including
punitive damages) for personal injuries arising from alleged exposures to
chromate-based products sold or allegedly sold by Betz Laboratories, Inc.
(predecessor to BetzDearborn) to PG&E for use in the cooling towers located at
these facilities. The sales in question occurred or allegedly occurred at
various times between 1952 and the mid-1980s, depending upon the facility. In
the Acosta, Aguilar, and Aguayo cases, the parties have selected 20 plaintiffs
and 2 alternates whose claims will be tried together, and prior to the claims
for the remaining plaintiffs in the Lawsuits. It is anticipated that the 20
plaintiffs' claims will be tried in late 1999. BetzDearborn denies any legal
liability to plaintiffs, believes it has substantial defenses, and intends to
contest the claims vigorously. BetzDearborn further believes that any claim for
punitive damages is without any legitimate basis in fact or law. The Lawsuits
are captioned as follows: Acosta, et al. v. Betz Laboratories, et al., No. BC
161 669 (1996); Adams, et al. v. Betz Laboratories, et al., No. BC 113 000
(1994); Aguilar, et al. v. Betz Laboratories, et al., No. BC 158 588 (1996); and
Aguayo et al. v. Betz Laboratories, et al., No. BC 123 749 (1995).

Although both BetzDearborn and PG&E are named as defendants in each of the
Lawsuits, not all plaintiffs seek damages from both defendants. PG&E previously
settled a lawsuit brought by many of the same individuals who are plaintiffs in
the Adams lawsuit; as a result, PG&E will have no additional liability to those
plaintiffs.

In October 1998, BetzDearborn and PG&E settled a fifth lawsuit relating to
alleged exposure to chromate-based products sold or allegedly sold by Betz
Laboratories, Inc. to PG&E for use in cooling towers at one or more of the PG&E
facilities. That lawsuit was captioned Riep, et al. v. Betz Laboratories, et
al., No. 984695 (San Francisco County, 1997). The amount of the settlement was
not material.



                                       46
<PAGE>   47
BetzDearborn maintained insurance coverage for the purpose of securing
protection against alleged product and other liabilities, and certain of the
insurance carriers have undertaken to pay the cost of the defense of the
Lawsuits subject to various reservations of rights. BetzDearborn will pursue all
available insurance coverage to fund any damages payable to plaintiffs in
connection with the Lawsuits (excluding any punitive damages to the extent not
recoverable under BetzDearborn's insurance policies).

While it is not feasible to predict the outcome of all pending suits and claims,
the ultimate resolution of these matters could have a material effect upon the
financial position of Hercules, and the resolution of any of the matters during
a specific period could have a material effect on the quarterly or annual
operating results for that period.

23.     CHANGE IN ACCOUNTING PRINCIPLE

In November 1997, FASB's Emerging Issues Task Force (EITF) reached a final
consensus on Issue 97-13, "Accounting for Costs Incurred in Connection With a
Consulting Contract That Combines Business Process Reengineering and Information
Technology Transformation." Activities deemed to be business process
reengineering include the following: current state assessments, configuring and
prototyping, process reengineering, and work force restructuring. The consensus
requires that the unamortized amounts of such costs previously capitalized as of
the beginning of the quarter, which includes November 20, 1997, be charged
during that quarter as the cumulative effect of a change in accounting
principle. The company adopted the consensus during the fourth quarter of 1997
and recorded a cumulative-effect adjustment of $5 million.

24.     OPERATIONS BY INDUSTRY SEGMENT AND GEOGRAPHIC AREA

In 1998, Hercules adopted Statement of Financial Accounting Standards (SFAS) No.
131, "Disclosures about Segments of an Enterprise and Related Information." The
statement establishes new standards for reporting information about operating
segments in annual financial statements and requires selected information about
operating segments in interim financial reports. It also establishes standards
for related disclosure about products and services, geographic area, and major
customers. In compliance with SFAS 131 and with the acquisition of BetzDearborn,
the company has identified three reportable segments and has restated prior
years to conform with the 1998 presentation.

Process Chemicals and Services: (Pulp and Paper and BetzDearborn.) Products and
services in this segment are designed to enhance customers' processes and
improve their manufacturing costs or environmental impact. Principal products
and markets include performance additives and water and process treatment
chemicals and related on-site services for a wide variety of industrial and
commercial applications including pulp and paper mills, refineries, chemical
plants, metals manufacturers, automobile assembly plants and makers of food and
beverages.

Functional Products: (Aqualon and Food Gums.) Products from this segment are
principally derived from natural resources and are sold as key raw materials to
other manufacturers. Principal products and markets include water-soluble
polymers and natural gums, used as thickeners, emulsifiers and stabilizers for
water-based paints, oil and gas exploration, building materials, dairy and
bakery products and other processed food products such as jams, jellies and
meats.

Chemical Specialties: (Resins and FiberVisions.) Products in this segment
provide low-cost, technology driven solutions to meet customer needs and market
demands. Principal products and markets include rosin and hydrocarbon resins for
adhesives used in nonwoven fabrics, textile fibers, and adhesive tapes;
thermal-bond polypropylene staple fiber for disposable diapers and other
hygienic products; and automotive textiles.

The company evaluates performance and makes decisions based primarily on "Profit
from Operations" and "Capital Employed." Consolidated capital employed
represents the total resources employed in the company and is the sum of total
debt, trust preferred securities and stockholders' equity. Capital employed in
each reportable segment represents the net operating assets employed to conduct
business in that segment and generally includes working capital (excluding cash)
and property, plant and equipment. Other assets and liabilities, primarily
goodwill and other intangibles, not specifically allocated to business segments,
are reflected in "Reconciling Items" in the table below.

Hercules has no single customer representing greater than 10% of its revenues.





                                       47
<PAGE>   48
GEOGRAPHIC REPORTING

For geographic reporting, no single country, outside the United States, is
material for separate disclosure. However, because the company has significant
foreign operations, revenues and long-lived assets are disclosed by geographic
region.

Revenues are reported on a "customer basis," meaning that net sales are included
in the geographic area where the customer is located. Long-lived assets are
included in the geographic areas in which the producing entities are located.

Intersegment sales are eliminated in consolidation.

BETZDEARBORN INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
SEPTEMBER 30, 1998 AND 1997

Note 1 - Basis of Presentation

The accompanying unaudited consolidated financial statements of BetzDearborn
Inc. (the "Company") for the nine-month periods ended September 30, 1998 and
1997 have been prepared in accordance with generally accepted accounting
principles for interim financial information and with the instructions to
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
considered necessary for fair presentation have been included. Certain amounts
in the financial statements for the year ended December 31, 1997 have been
reclassified to conform with 1998 classifications. Operating results for the
nine-month period ended September 30, 1998 are not necessarily indicative of the
results for the full year ended December 31, 1998.

Financial Accounting Standards Board Statement No. 130, "Reporting Comprehensive
Income," requires the Company to report in its financial statements all
non-owner related changes in equity for the periods being reported.
Comprehensive income for the nine-month periods ended September 30, 1998 and
1997 was $38 million and $24 million, respectively, consisting of net income and
foreign currency translation adjustments.

In the fourth quarter of 1997, the Company changed its method of accounting for
business process reengineering costs incurred in connection with its ongoing
major project that combined business process reengineering and information
technology transformation. This accounting change was mandated by the consensus
position of the Financial Accounting Standards Board's Emerging Issues Task
Force (Issue No. 97-13). Effective October 1, 1997, all such costs were expensed
as incurred, whereas previously such costs were capitalized. In the fourth
quarter of 1997, business process reengineering costs capitalized through
September 30, 1997 were written off as a cumulative effect type adjustment.

Note 2 - Common Shares Reserved for Stock Plans

At September 30, 1998, 4,917,827 and 426,482 Common Shares were reserved for
possible issuance pursuant to the exercise of stock options and grants under the
Company's Stock Option and Incentive Plans, respectively. An additional 256,508
Common Shares were reserved for purchase through payroll deductions under the
terms of the Employee Stock Purchase Plan. Further, 2,673,000 Common Shares were
reserved for possible conversion of the Series A ESOP Convertible preferred
stock.

PRO FORMA FINANCIAL STATEMENTS OF HERCULES INCORPORATED (Unaudited)

The Unaudited Pro Forma Condensed Combined Statement of Income of Hercules
Incorporated for the year ended December 31, 1998 reflects the acquisition of
BetzDearborn Inc. as if it had occurred at the beginning of the year ended
December 31, 1998. The pro forma information is based on the historical
financial statements of Hercules and BetzDearborn after giving effect to the
acquisition using the purchase method of accounting and a preliminary purchase
price allocation. The actual allocation of the purchase price is expected to be
completed during 1999, based on a complete evaluation of the assets acquired and
liabilities assumed. Accordingly, the information presented herein may differ
from the final purchase price allocation. The Unaudited Pro Forma Condensed
Combined Statement of Income also reflects assumptions and adjustments deemed
appropriate by Hercules management, which are described in the accompanying
notes to the Unaudited Pro Forma Condensed Combined Statement of Income. Cost
savings benefits from synergies to be derived from the planned acquisition,
which may be significant, are not reflected in the Unaudited Pro Forma Condensed
Combined Statement of Income.

The Unaudited Pro Forma Condensed Combined Statement of Income does not purport
to be indicative of Hercules' results of operations had the planned acquisition
actually occurred on the date assumed nor is it necessarily indicative of
Hercules' future operating results. The Unaudited Pro Forma Condensed Combined
Statement of Income should be read in conjunction with the audited consolidated
financial statements of Hercules and the notes thereto set forth in Part II,
Item 8, of this Form 10-K, and the historical consolidated financial statements
of BetzDearborn and the notes thereto set forth in BetzDearborn's 1997 Annual
Report on Form 10-K and the unaudited financial statements of BetzDearborn for
the periods ended March 31, 1998 and June 30, 1998, as set forth in its
quarterly reports on Form 10-Q for those periods.

         useful lives.

(b)      To record amortization of goodwill of $2,074 over its estimated useful
         life of 40 years, and amortization of other identified intangible

         years.

(c)      To eliminate historical BetzDearborn goodwill and intangible

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders or by holders of Preferred Securities may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders
or holders of Preferred Securities, as applicable, 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

authorization, direction, notice, consent, waiver or other action, the Company
may, at its option, by or pursuant to a resolution of its Board of Directors,

period or periods within which, the price or prices at which, and the terms and

issuances of additional Debentures of such series or to establish additional
terms of such series of Debentures.

         If any of the terms of the Debentures of any series shall be
established by action taken by or pursuant to a Board Resolution, the Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the

                                       10
<PAGE>   17
         (c) interest on any Debenture shall be paid on each Interest Payment
Date therefor to the Holder thereof at the close of business on the Record Date
therefor, such interest to be payable by check mailed to the address of the
Person entitled thereto as such address appears on the Register; provided
however, that (i) at the written request of any Holder of at least $10,000,000
aggregate principal amount of Debentures received by the Registrar not later
than the Regular Record Date for such Interest Payment Date, interest accrued on
such Debentures will be payable by wire transfer within the continental United
States in immediately available funds to the bank account number of such Holder
specified in such request and entered on the Register by the Registrar and (ii)
payments made in respect of Global Debentures shall be made in immediately
available funds to the Depository.

provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Debenture (or one or more Predecessor Debentures) is registered at the
close of business on the Regular Record Date for such interest. Any interest on
any Debenture which is payable, but is not punctually paid or duly provided for,
on any Interest Payment Date (herein called "Defaulted Interest") shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date
by virtue of having been such Holder, and such Defaulted Interest may be paid by
the Company, at its election in each case, as provided in clause (i) and (ii)
below:

                  (i) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Debentures (or their
         respective Predecessor Debentures) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall, not less than 15 Business Days prior to the date of the proposed
         payment, notify the Trustee and the Paying Agent in writing of the
         amount of Defaulted Interest proposed to be paid on each Debenture and
         the date of the proposed payment, and at the same time the Company
         shall deposit with the Paying Agent 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 Paying Agent
         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 provided in this clause. The
         Special Record Date for the payment of such Defaulted Interest shall be
         the close of business not more than 15 nor less than 10 days prior to
         the date of the proposed payment. The Trustee shall, in the name and at
         the expense of the Company, cause notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor to be
         given to the Holders thereof, 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 given, such
         Defaulted Interest shall be paid to the Persons in whose names the
         Debentures (or their respective Predecessor Debentures) are registered
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (ii).

                  (ii) The Company may make payment of any Defaulted Interest on
         the Debentures in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which such Debentures may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Company to the Trustee and the Paying Agent
         of the proposed payment pursuant to this clause, such manner of payment
         shall be deemed practicable by the Paying Agent.


                                       11
<PAGE>   18
         Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Debenture shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Debenture.

         If any convertible Debenture of any series is converted after any
Regular Record Date and on or prior to the next succeeding Interest Payment Date
(other than any Debenture with respect to which the Stated Maturity Date is
prior to such Interest Payment Date), interest that is due 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 Debenture is registered at
the close of business on such Regular Record Date. Except as otherwise expressly
provided in the immediately preceding sentence, in the case of any Debenture
that is converted, interest shall not be payable if the Regular Record Date is
after the date of conversion of such Debenture.

SECTION 2.03      EXECUTION, AUTHENTICATION AND DELIVERY.

         (a) The Debentures shall be executed on behalf of the Company by either

Secretary or one of its Assistant Secretaries. The signature of any such Officer
on the Debentures may be manual or facsimile.

         (b) Debentures bearing the manual or facsimile signatures of
individuals who were at any time the proper Officers of the Company shall bind

hold such offices prior to the authentication and delivery of such Debentures or
did not hold such offices at the date of such Debentures.

         (c) No Debenture shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Debenture
a Certificate of Authentication duly executed by the Trustee by manual signature
of a Responsible Officer, and such Certificate of Authentication upon any
Debenture shall be conclusive evidence, and the only evidence, that such
Debenture has been duly authenticated and made available for delivery hereunder.

         (d) The Trustee shall authenticate and deliver Debentures of a series,
for original issue, at one time or from time to time in accordance with the
Company Order referred to below, upon receipt by the Trustee of:

                  (iv) such Debentures, executed on behalf of the Company in
         accordance with clause (a) of this Section;

                  (v) an Opinion of Counsel to the effect that:

                         (1) the form or forms of such Debentures have been duly
                  authorized by the Company and have been established in
                  conformity with the provisions of this Indenture;

                         (2) such Debentures, when authenticated and delivered
                  by the Trustee and issued and delivered by the Company in the
                  manner and subject to any conditions specified in such Opinion
                  of Counsel, will have been duly issued under this Indenture
                  and will constitute valid and legally binding obligations of
                  the Company, entitled to the benefits provided by this
                  Indenture, and enforceable in accordance with their terms,
                  subject, as to enforcement to laws relating to or affecting
                  generally the enforcement of creditors' rights, including,
                  without limitation, bankruptcy and insolvency laws and to
                  general principles of equity (regardless of whether such
                  enforceability is considered in a proceeding in equity or at
                  law);

                         (3) that any supplemental indenture referred to in
                  clause (iii) above has been duly authorized, executed and
                  delivered by the Company and is a valid instrument legally
                  binding upon the Company, enforceable in accordance with its
                  terms, subject as to enforcement to laws relating to or
                  affecting creditors' rights, including without limitation,
                  bankruptcy and insolvency laws and to general principles of
                  equity (regardless of whether such enforceability is
                  considered in a proceeding in equity or at law); and

                         (4) that all consents, approvals and orders of any
                  commission, governmental authority or agency required in
                  connection with the issuance and delivery of such Debentures
                  have been obtained; and

                  (vi) an Officers' Certificate certifying that no Default or
         Event of Default has occurred and is continuing.

         (e) The Trustee shall act as the initial authenticating agent.
Thereafter, the Trustee may appoint an authenticating agent. Each authenticating
agent shall be acceptable to the Company and, except as provided in or pursuant
to this Indenture, shall at all times be a corporation that would be permitted
by the TIA to act as trustee under an indenture qualified under the TIA, is
authorized under applicable law and by its charter to act as an authenticating
agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the TIA) of at least $50,000,000. If at any time an
authenticating agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section. An authenticating agent may authenticate
Debentures whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by an authenticating
agent. The Trustee shall pay any authenticating agent appointed by the Trustee
reasonable compensation for its services and the Trustee shall be reimbursed for
such payment by the Company pursuant to Section 7.06. The provisions set forth
in Sections 7.02, 7.03 and 7.06 shall be applicable to any authenticating agent.


                                       13
<PAGE>   20
         (f) If all the Debentures of any series are not to be issued at one
time, it shall not be necessary to deliver an Opinion of Counsel and an
Officers' Certificate at the time of issuance of each Debenture, but such
opinion and certificate, with appropriate modifications, shall be delivered at
or before the time of issuance of the first Debenture of such series. After any
such first delivery, any separate request by the Company that the Trustee
authenticate Debentures of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Debentures continue to
have been complied with.

SECTION 2.04      REGISTRAR AND PAYING AND CONVERSION AGENTS.

         The Company shall maintain or cause to be maintained, in the City of
New York, an Office or Agency where the Debentures may be presented for
registration of transfer or for exchange ("Registrar"), a Paying Agent at whose
Office the Debentures may be presented or surrendered for payment, a Conversion
Agent at whose Office the Debentures may be presented and surrendered in the
event of a conversion or exchange ("Conversion Agent"), and an Office or Agency
where notices and demands to or upon the Company in respect of the Debentures
and this Indenture may be served. The Registrar shall keep a register (the
"Register") of the Debentures and of their transfer and exchange. The Company
may have one or more co-Registrars and one or more additional Paying Agents and
Conversion Agents. The term Registrar includes any additional registrar, the
term Paying Agent includes any additional paying agent and the term Conversion
Agent includes any additional conversion agent.

         Unless otherwise specified in or pursuant to this Indenture or the
Debentures, the Trustee shall be the initial Registrar for each series of
Debentures. The Company shall have the right to remove and replace from time to
time the Registrar for any series of Debentures; provided that no such removal
or replacement shall be effective until a successor Registrar with respect to
such series of Debentures shall have been appointed by the Company and shall
have accepted such appointment by the Company. In the event that the Trustee
shall not be or shall cease to be Registrar with respect to a series of
Debentures, it shall have the right to examine the Register for such series at
all reasonable times. There shall be only one Register for each series of
Debentures.

         The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-Registrar (if not the Company or
the Trustee or an Affiliate of the Trustee). The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall give
prompt written notice to the Trustee and to the Holders of any change of
location of such Office or Agency. If at any time the Company shall fail to
maintain or cause to be maintained any such required Office or Agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 13.02 hereof. The Company shall notify the Trustee
of the name and address of any such agent. If the Company fails to maintain a
Registrar, Paying Agent, Conversion Agent or agent for service of notices or
demands, the Trustee shall act as such and shall be entitled to appropriate
compensation therefor pursuant to Section 7.06. The Company or any Affiliate of
the Company may act as Paying Agent, Registrar, Conversion Agent or co-Registrar
or agent for service of notices and demands.

         The Company may also from time to time designate one or more other
Offices or Agencies where the Debentures may be presented or surrendered for any
or all such purposes and may from time to time 


                                       14
<PAGE>   21
rescind such designations. The Company will give prompt written notice to the
Trustee and to the Holders of any such designation or rescission and of any
change in location of any such other Office or Agency.

SECTION 2.05      PAYING AGENT TO HOLD MONEY IN TRUST.

         Except as otherwise provided herein, prior to or on each due date of
the principal of and premium, if any, and interest on any Debenture, the Company
shall deposit with the Paying Agent a sum of money sufficient to pay such
principal, premium, if any, and interest so becoming due. The Company shall
require each Paying Agent (other than the Trustee or the Company) to agree in
writing that such Paying Agent shall hold in trust for the benefit of Holders or
the Trustee all money held by the Paying Agent for the payment of principal of
and premium, if any, and interest on the Debentures and shall notify the Trustee
of any default by the Company in making any such payment. At any time during the
continuance of any such default, the Paying Agent shall, upon the request of the
Trustee, pay to the Trustee all money so held in trust and account for any money
disbursed by it. The Company at any time may require the Paying Agent to pay all
money held by it to the Trustee and to account for any money disbursed by it.
Upon doing so, the Paying Agent shall have no further liability for the money so
paid over to the Trustee. If the Company, a Subsidiary or an Affiliate of either
of them acts as Paying Agent, it shall segregate the money held by it as Paying
Agent and hold it as a separate trust fund.

SECTION 2.06      DEBENTUREHOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable, the most recent list available to it of the names and addresses of
Debentureholders. If the Trustee is not the Registrar, the Company shall cause
to be furnished to the Trustee on or before the Record Date for each Interest
Payment Date and at such other times as the Trustee may request in writing,
within five Business Days of such request, a list, in such form as the Trustee
may reasonably require of the names and addresses of Debentureholders.

SECTION 2.07      TRANSFER AND EXCHANGE.

         When Debentures are presented to the Registrar or a co-Registrar with a
request to register the transfer or to exchange them for an equal principal
amount of Debentures of the same series of other authorized denominations, the
Registrar shall register the transfer or make the exchange as requested if its
reasonable requirements for such transactions are met. To permit registrations
of transfer and exchanges, the Company shall execute and the Trustee shall
authenticate Debentures, all at the Registrar's request.

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

         The Company shall not require payment of a service charge for any
registration of transfer or exchange of Debentures, but the Company may require
payment of a sum sufficient to pay all taxes, assessments or other governmental
charges that may be imposed in connection with the registration of the transfer
or exchange of Debentures from the Debentureholder requesting such transfer or
exchange (other than any exchange of a temporary Debenture for a definitive
Debenture not involving any change in ownership).


                                       15
<PAGE>   22
         The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of (a) any Debenture for a period beginning at
the opening of business 15 days before the mailing of a notice of redemption of
Debentures and ending at the close of business on the day of such mailing or (b)
any Debenture selected, called or being called for redemption, except, in the
case of any Debenture to be redeemed in part, the portion thereof not to be
redeemed.

SECTION 2.08      REPLACEMENT DEBENTURES.

         If (a) any mutilated Debenture is surrendered to the Company or the
Trustee, or (b) the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Debenture, and there is
delivered to the Company and the Trustee such Debenture or indemnity as may
reasonably be required by them to save each of them harmless, then, in the
absence of notice to the Company or the Trustee that such Debenture has been
acquired by a bona fide purchaser, the Company shall execute in exchange for any
such mutilated Debenture, or in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of the same series and of like tenor and principal
amount, bearing a number not contemporaneously outstanding, and the Trustee
shall authenticate and make such new Debenture available for delivery.

         In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, or is about to be redeemed by the
Company pursuant to Article 3, the Company in its discretion may, instead of
issuing a new Debenture, pay or purchase such Debenture, as the case may be.

         Upon the issuance of any new Debentures 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 reasonable fees and expenses of the Trustee) in
connection therewith.

         Every new Debenture issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Debenture shall constitute an original
additional contractual obligation of the Company (whether or not the mutilated,
destroyed, lost or stolen Debenture shall be at any time enforceable) and shall
be entitled to all benefits of this Indenture equally and ratably with any and
all other Debentures 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 Debentures.

SECTION 2.09      OUTSTANDING DEBENTURES; DETERMINATIONS OF HOLDERS' ACTION.

         Debentures outstanding at any time are all the Debentures authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those mutilated, destroyed, lost or stolen Debentures referred to
in Section 2.08, those redeemed by the Company pursuant to Article 3, and those
described in this Section as not outstanding. A Debenture does not cease to be
outstanding because the Company or a Subsidiary or Affiliate thereof holds the
Debenture; provided, however, that in determining whether the Holders of the
requisite principal amount of Debentures have given or concurred in any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Debentures owned by the 


                                       16
<PAGE>   23
Company or a Subsidiary or Affiliate (other than any Trust so long as any of the
Preferred Securities of such Trust are outstanding) shall be disregarded and
deemed not to be outstanding.

         Subject to the foregoing, only Debentures outstanding at the time of
such determination shall be considered in any such determination (including
determinations pursuant to Articles 3, 6 and 9).

         If a Debenture is replaced pursuant to Section 2.08, it ceases to be
outstanding unless the Trustee receives proof reasonably satisfactory to it that
the replaced Debenture is held by a bona fide purchaser.

         If the Paying Agent (other than the Company) holds, in accordance with
this Indenture, at the Stated Maturity Date or on a Redemption Date, money
sufficient to pay the Debentures payable on that date, then immediately on the
Stated Maturity Date or such Redemption Date, as the case may be, such
Debentures shall cease to be outstanding, and interest, if any, on such
Debentures shall cease to accrue.

SECTION 2.10      TEMPORARY DEBENTURES.

         The Company may execute temporary Debentures, and upon the Company's
Order, the Trustee shall authenticate and make such temporary Debentures
available for delivery. Temporary Debentures shall be printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
in the same series and principal amount and of like tenor as the definitive
Debentures in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the Officers of the
Company executing such Debentures may determine, as conclusively evidenced by
their execution of such Debentures. Such temporary Debentures may be in global
form.

         Except in the case of temporary Debentures in global form, which shall
be exchanged in accordance with the provisions thereof, after the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures of the same series upon surrender of the temporary
Debentures at the Office or Agency of the Company designated for such purpose
pursuant to Section 2.04, without charge to the Holders thereof. Upon surrender
for cancellation of any one or more temporary Debentures, the Company shall
execute a like principal amount of definitive Debentures of the same series of
authorized denominations, and the Trustee, upon receipt of a Company Order,
shall authenticate and make such Debentures available for delivery in exchange
therefor. Until so exchanged, the temporary Debentures shall in all respects be
entitled to the same benefits under this Indenture as definitive Debentures.

SECTION 2.11      BOOK-ENTRY SYSTEM.

         In order to utilize a book-entry-only system for all or any portion of
the Debentures of any series, all or a portion of the Debentures of any series
may be issued in the form of one or more fully registered Debentures of the same
series for the aggregate principal amount of such Debentures (a "Global
Debenture"), which Global Debenture shall be registered in the name of the
depository (the "Depository") selected by the Company or in the name of such
Depository's nominee. Each Global Debenture shall be delivered by the Trustee to
the Depository or pursuant to the Depository's instruction and shall bear a
legend substantially to the following effect: "This Debenture may be
transferred, in whole but not in part, only to another nominee of the Depository
or to a successor Depository or to a nominee of such successor Depository."


                                       17
<PAGE>   24
         Notwithstanding any other provision of this Section or of Section 2.07,
a Global Debenture may be transferred in whole but not in part and in the manner
provided in Section 2.07, only by a nominee of the Depository for such series,
or by the Depository or any such nominee of a successor Depository for such
series selected or approved by the Company or to a nominee of such successor
Depository.

         If (a) at any time the Depository for Global Debentures of any series
of Debentures notifies the Company that it is unwilling or unable to continue as
Depository for such Global Debentures or if at any time the Depository for such
Global Debentures shall no longer be a clearing agency registered or in good
standing under the Exchange Act or other applicable statute or regulation, and a
successor Depository for such Global Debentures is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
condition, as the case may be, (b) the Company determines in its sole
discretion, that the Debentures of any series shall no longer be represented by
one or more Global Debentures and delivers to the Trustee an Officers'
Certificate evidencing such determination or (c) a Default or an Event of
Default occurs and is continuing, then the provisions of this Section shall no
longer apply to the Debentures of such series. In such event, the Company will
execute and the Trustee, upon receipt of an Officers' Certificate evidencing
such determination by the Company, will authenticate and deliver Debentures of
such series and of like tenor in definitive registered form, in authorized
denominations, and in aggregate principal amount equal to the principal amount
of the Global Debentures of such series in exchange for such Global Debentures.
Upon the exchange of Global Debentures for such Debentures in definitive
registered form without coupons, in authorized denominations, the Global
Debentures shall be canceled by the Trustee. Such Debentures in definitive
registered form issued in exchange for Global Debentures pursuant to this
Section shall be registered in such names and in such authorized denominations
as the Depository, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Debentures to the Persons in whose names such Debentures are so registered.

         Except as provided above or as provided in any supplemental indenture,
owners of beneficial interests in a Global Debenture shall not be entitled to
receive physical delivery of Debentures in definitive form and will not be
considered the Holders thereof for any purpose under this Indenture.

         Members of or participants in the Depository shall have no rights under
this Indenture with respect to any Global Debenture held on their behalf by the
Depository, and such Depository or its nominee, as the case may be, may be
treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the Holder of such Global Debentures for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its members or participants, the
operation of customary practices governing exercise of the rights of a Holder of
any Debenture, including without limitation the granting of proxies or other
authorization of participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action which a Holder
is entitled to give or take under this Indenture.

SECTION 2.12      CANCELLATION.

         All Debentures surrendered for payment, redemption, registration of
transfer, exchange or conversion or for credit against any sinking fund payment
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee and shall be promptly canceled by the Trustee. The Company 


                                       18
<PAGE>   25
may at any time deliver to the Trustee for cancellation any Debentures
previously authenticated and made available for delivery hereunder which the
Company may have acquired in any manner whatsoever, and all Debentures so
delivered shall be promptly canceled by the Trustee. The Company may not reissue
or issue new Debentures to replace Debentures it has paid or delivered to the
Trustee for cancellation. No Debentures shall be authenticated in lieu of or in
exchange for any Debentures canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Debentures held by the
Trustee shall be destroyed by the Trustee, and the Trustee shall deliver a
certificate of destruction to the Company.


                                    ARTICLE 3
                                   REDEMPTION

         (a) The Company may redeem the Debentures of any series issued
hereunder on and after the dates and in accordance with the terms established
for such series pursuant to Section 2.01.

         (b) If any or all of the Debentures are to be redeemed pursuant to this
Section, the Company shall deliver to the Trustee no more than 60 and no less
than 45 days prior to the Redemption Date a Company Order specifying the series
and principal amount of Debentures to be redeemed and the Redemption Date and
Redemption Price for such Debentures. Such Company Order shall be accompanied by
a Board Resolution authorizing such redemption. If the Debentures of a series
are held by a Trust, the Company shall also deliver a copy of such Company Order
to the Property Trustee for such Trust.

SECTION 3.02      SELECTION OF DEBENTURES TO BE REDEEMED.

         If less than all the outstanding Debentures of a series are to be
redeemed at any time, the Trustee shall select the Debentures of such series to
be redeemed by lot or by any other method the Trustee considers fair and
appropriate. The Trustee shall make the selection at least 30 but not more than
60 days before the Redemption Date from outstanding Debentures of such series
not previously called for redemption. Provisions of this Indenture that apply to
Debentures called for redemption also apply to portions of Debentures called for
redemption. The Trustee shall notify the Company promptly of the Debentures or
portions of Debentures to be redeemed.

SECTION 3.03      NOTICE OF REDEMPTION.

         At least 30 days but not more than 60 days before the Redemption Date,
the Trustee, in the Company's name and at the Company's expense, shall mail or
cause to be mailed a notice of redemption by first-class mail, postage prepaid,
to each Holder of Debentures to be redeemed at such Holder's last address as it
appears in the Register.

         The notice of redemption shall identify the Debentures to be redeemed,
the provision of the Debentures or this Indenture pursuant to which the
Debentures called for redemption are being redeemed and shall state:


                                       19
<PAGE>   26
         (a) the Redemption Date;

         (b) the Redemption Price;

         (c) the name and address of the Paying Agent;

         (d) that payment of the Redemption Price of Debentures called for
redemption will be made only upon surrender of such Debentures to the Paying
Agent;

         (e) if fewer than all the outstanding Debentures of any series are to
be redeemed, the identification and principal amounts of the particular
Debentures to be redeemed and that, on and after the Redemption Date, upon
surrender of such Debentures, a new Debenture or Debentures of the same series
and of like tenor and in a principal amount equal to the unredeemed portion
thereof will be issued;

         (f) that, unless the Company defaults in paying the Redemption Price of
the Debentures called for redemption, including accrued interest thereon to the
Redemption Date, interest will cease to accrue on such Debentures on and after
the Redemption Date;

         (g) that the redemption is for a sinking fund, if such is the case; and

         (h) in the case of Debentures of any series that are convertible or
exchangeable into Capital Stock, the conversion or exchange price or rate, the
date or dates on which or the period or periods during which the right to
convert or exchange the principal of the Debentures of such series to be
redeemed will commence or terminate and the place or places where such
Debentures may be surrendered for conversion or exchange.

         Any notice of redemption given in the manner provided herein shall be
conclusively presumed to have been given, whether or not such notice is actually
received. Failure to mail any notice or defect in the mailed notice or the
mailing thereof in respect of any Debenture shall not affect the validity of the
redemption of any other Debenture.

SECTION 3.04      EFFECT OF NOTICE OF REDEMPTION.

         After notice of redemption has been given, Debentures called for
redemption shall become due and payable on the Redemption Date at the Redemption
Price and from and after the Redemption Date (unless the Company shall default
in the payment of the Redemption Price and accrued interest), such Debentures
shall cease to bear interest. Upon the later of the Redemption Date and the date
such Debentures are surrendered to the Paying Agent, such Debentures shall be
paid at the Redemption Price, plus accrued interest to the Redemption Date,
provided that installments of interest on Debentures with an Interest Payment
Date which is on or prior to the Redemption Date shall be payable to the Holders
of such Debentures, registered as such at the close of business on the Regular
Record Dates therefor according to their terms and provisions.

SECTION 3.05      DEPOSIT OF REDEMPTION PRICE.

         On or prior to the Redemption Date, the Company shall deposit with the
Paying Agent (or if the Company or an Affiliate is the Paying Agent, shall
segregate and hold in trust or cause such Affiliate to segregate and hold in
trust) money sufficient to pay the Redemption Price of, and accrued interest on,
all Debentures to be redeemed on that Redemption Date. The Paying Agent shall
return to the Company any money in excess of the amount sufficient to pay the
Redemption Price of, and accrued interest on, all Debentures to be redeemed and
any interest accrued on the amount deposited pursuant to this Section.

SECTION 3.06      DEBENTURES REDEEMED IN PART.

         Upon surrender of a Debenture that is redeemed in part, the Trustee
shall authenticate for the Holder a new Debenture of the same series and in a
principal amount equal to the unredeemed portion of such Debenture.


                                    ARTICLE 4

SECTION 4.01      PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST

         (a) The Company shall pay the principal of and premium, if any, and
interest (including interest accruing during any Extension Period and/or on or
after the filing of a petition in bankruptcy or reorganization relating to the
Company, whether or not a claim for post-filing interest is allowed in such
proceeding) on the Debentures on or prior to the dates and in the manner
provided in such Debentures or pursuant to this Indenture. An installment of
principal, premium, if any, or interest shall be considered paid on the
applicable due date if on such date the Trustee or the Paying Agent holds, in
accordance with this Indenture, money sufficient to pay all of such installment
then due. With respect to any Debenture, the Company shall pay interest on
overdue principal and interest on overdue installments of interest (including
interest accruing during any Extension Period and/or on or after the filing of a
petition in bankruptcy or reorganization relating to the Company, whether or not
a claim for post-filing interest is allowed in such proceeding), to the extent
lawful, at the rate accruing on such Debenture, compounded with the same
frequency as interest is payable on such Debentures. Interest on overdue
interest shall accrue from the date such amounts become overdue.

         (b) Notwithstanding the provisions of Section 4.01(a) or any other
provision herein to the contrary, the Company shall have the right, as provided
in a Board Resolution or supplemental indenture issued pursuant to Section 2.01,
in its sole and absolute discretion at any time and from time to time while the
Debentures of any series are outstanding, so long as no Event of Default with
respect to such series of Debentures has occurred and is continuing, to defer
payments of interest by extending the interest payment period for such series of
Debentures for the maximum consecutive period, if any, specified for such series
of Debentures, provided that such Extension Period must end on an Interest
Payment Date and shall not extend beyond the Stated Maturity Date or Redemption
Date of any Debenture of such series, and provided further that at the end of
each Extension Period the Company shall pay all interest then accrued and unpaid
(together with interest thereon to the extent permitted by applicable law at the
rate accruing on such Debentures). Prior to the termination of an Extension
Period, the Company may shorten or may further extend the interest payment
period for such series of Debentures, provided that such 


                                       21
<PAGE>   28
Extension Period together with all such previous and further extensions may not
exceed the maximum consecutive period specified for such series of Debentures,
end on a date other than an Interest Payment Date or extend beyond the Stated
Maturity Date or Redemption Date of any Debenture of such series. The Company
shall give the Trustee notice of the Company's election to begin an Extension
Period for any series of Debentures and any shortening or extension thereof at
least five Business Days prior to: (i) the date notice of payment of interest on
such Debentures is required to be given to any national securities exchange on
which the related Preferred Securities, if any, or Debentures are then listed or
other applicable self-regulatory organization or (ii) the date of the notice of
the record or payment date of the related distribution on the Preferred
Securities issued by the Trust which is the Holder of the Debentures of such
series, but in any event not less than five Business Days prior to the Record
Date fixed by the Company for the payment of such interest. The Company shall
give or cause the Trustee to give notice (a form of which shall be provided by
the Company to the Trustee) of the Company's election to begin an Extension
Period to the Holders by first class mail, postage prepaid.

SECTION 4.02      PROHIBITION AGAINST DIVIDENDS, ETC.

         The Company shall not (a) declare or pay any dividends or distributions
on, or redeem, purchase, acquire, or make a liquidation payment with respect to,
any of the Company's Capital Stock or (b) make any payment of principal of or
premium, if any, or interest on or repay or repurchase or redeem any debt
securities of the Company (including Debentures) that rank pari passu with or
junior in right of payment to the Debentures or (c) make any guarantee payments
with respect to any guarantee by the Company of the debt securities of any
Subsidiary of the Company (including any Guarantee) if such guarantee ranks pari
passu or junior in right of payment to the Debentures (other than (i) dividends
or distributions in shares of, or options, warrants or rights to subscribe for
or purchase shares of, Common Stock of the Company, (ii) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
or the issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (iii) payments under any
Guarantee, (iv) 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, (v) 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, and (vi) purchases of Common Stock
related to the issuance of Common Stock or rights under any of the Company's
benefit plans for its directors, officers or employees or any of the Company's
dividend reinvestment plans): (X) during any Extension Period, (Y) if at such
time there shall have occurred and is continuing any Default or Event of
Default, or (Z) if the Company shall be in default with respect to its payment
or other obligations under any Guarantee.

SECTION 4.03      SEC REPORTS.

         The Company shall file with the Trustee, within 15 days after it files
them with the SEC, copies of its annual report and of the information, documents
and other reports (or copies of such portions of any of the foregoing as the SEC
may by rules and regulations prescribe) which the Company is required to file
with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. If the Company
is not subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, the Company shall file with the Trustee such information,
documents and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) which are specified in
Section 13 or 15(d) of the Exchange Act. The Company shall also comply with the
provisions of Section 314(a) of the TIA.

SECTION 4.04      COMPLIANCE CERTIFICATES.

         (a) The Company shall deliver to the Trustee, within 120 days after the
end of each of the Company's fiscal years, an Officers' Certificate stating
whether or not the signer knows of any Default or Event of Default. Such
certificate shall contain a certification from the Principal Executive Officer,
Principal Financial Officer or Principal Accounting Officer of the Company as to
his or her knowledge of the Company's compliance with all conditions and
covenants under this Indenture. For purposes of this Section, such compliance
shall be determined without regard to any period of grace or requirement of
notice provided under this Indenture. If such Officer does know of such a
Default or Event of Default, the Officers' Certificate shall describe any such
Default or Event of Default, and its status. Such Officers' Certificate need not
comply with Sections 13.04 and 13.05.

         (b) The Company shall deliver to the Trustee any information reasonably
requested by the Trustee in connection with the compliance by the Trustee or the
Company with the TIA.

SECTION 4.05      FURTHER INSTRUMENTS AND ACTS.

         Upon request of the Trustee, the Company shall execute and deliver such
further instruments and do such further acts as may be reasonably necessary or
proper to carry out more effectively the purposes of this Indenture.

SECTION 4.06      PAYMENT OF EXPENSES OF EACH TRUST.

         The Company covenants for the benefit of the Holders of each series of
Debentures to pay all of the obligations, costs and expenses of such Trust
(other than payments in respect of Trust Securities) in accordance with the
provisions of its Trust Agreement and to pay the taxes of such Trust in
accordance with the provisions of its Trust Agreement in order to permit such
Trust to make distributions on and redemptions of its Preferred Securities in
accordance with such Trust Agreement.

SECTION 4.07      OWNERSHIP OF COMMON SECURITIES.

         So long as the Trust Securities of each Trust remain outstanding, the
Company hereby covenants (a) to maintain 100% direct or indirect ownership of
the common securities issued by such Trust (it being understood that any
permitted successor of the Company under this Indenture may succeed to the
Company's ownership of such common securities), (b) to use its best efforts to
cause each Trust (i) to remain a business trust, except in connection with the
distribution of Debentures to the holders of related Trust Securities in
liquidation of such Trust, the conversion, exchange or redemption of all of such
Trust Securities, or certain mergers, consolidations or amalgamations, each as
permitted by the applicable Trust Agreement, and (ii) to otherwise continue to
be classified as a grantor trust for United States federal income tax purposes,
(c) to use its best efforts to cause each holder of each Trust's Trust
Securities to be treated as owning an undivided beneficial interest in the
related Debentures and (d) not to cause, as sponsor of each Trust, or to permit,
as holder of the common securities, the dissolution, liquidation or winding-up
of any Trust, except as provided in the applicable Trust Agreement.

                              SUCCESSOR CORPORATION

SECTION 5.01      WHEN THE COMPANY MAY MERGE, ETC.

         The Company may not consolidate with or merge with or into, or sell,
convey, transfer or lease its properties and assets as an entirety or
substantially as an entirety (either in one transaction or a series of
transactions) to, any Person, and no Person shall consolidate with or merge into
the Company or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to the Company, unless:

         (a) the Person formed by or surviving such consolidation or merger or
to which such sale, conveyance, transfer or lease shall have been made (the
"Successor") if other than the Company (i) is organized and existing under the
laws of the United States of America or any state thereof or the District of
Columbia, and (ii) shall expressly assume by a supplemental indenture, executed
and delivered to the Trustee, in form satisfactory to the Trustee, all the
obligations of the Company under the Debentures, this Indenture and the
Guarantees;

         (b) immediately prior to and after giving effect to such transaction
(and treating any Indebtedness which becomes an obligation of the Successor
Person or any Subsidiary as a result of such transaction as having been incurred
by such Person or such Subsidiary at the time of such transaction), no Default
or Event of Default shall have occurred and be continuing; and

         (c) the Company delivers to the Trustee an Officers' Certificate and an
Opinion of Counsel, each stating that such consolidation, merger, sale,
conveyance, transfer or lease and such supplemental indenture comply with this
Indenture.

         The Successor will be the successor to the Company, and will be
substituted for, and may exercise every right and power and become the obligor
on the Debentures with the same effect as if the Successor had been named as the
Company herein but, in the case of a sale, conveyance, transfer or lease of all
or substantially all of the assets of the Company, the predecessor Company will
not be released from its obligation to pay the principal of and premium, if any,
and interest on the Debentures.

                              DEFAULTS AND REMEDIES

SECTION 6.01      EVENTS OF DEFAULT.

         "Event of Default," wherever used herein with respect to Debentures of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless such event is specifically deleted or modified in or pursuant to the
supplemental indenture, Board Resolution or Officers' Certificate establishing
the terms of such series pursuant to this Indenture:


                                       24
<PAGE>   31
         (a) default in the payment, when due, of interest on any Debenture of
that series and the default continues for a period of 30 days; provided, that
during any Extension Period for the Debentures of that series, failure to pay
interest on the Debentures of that series shall not constitute a Default or
Event of Default hereunder, or

         (b) default in the payment of the principal of or premium, if any, on
any Debenture of such series when it becomes due, whether at maturity, upon any
redemption, by declaration of acceleration of maturity or otherwise; or

         (c) default in the deposit of any sinking fund payment when and as due
by the terms of a Debenture of such series; or

         (d) default in the performance or breach of any covenant or agreement
of the Company in this Indenture (other than a covenant or agreement a default
in the performance or the breach of which is elsewhere in this Section
specifically dealt with or which has been expressly included in this Indenture
solely for the benefit of a series of Debentures), and continuance of such
breach or default for a period of 90 days after receipt by the Company of a
"Notice of Default"; or

         (e) a court of competent jurisdiction enters:

                  (i) a decree or order for relief in respect of the Company in
         an involuntary proceeding under any applicable Bankruptcy Law and such
         decree or order shall remain unstayed and in effect for a period of 60
         consecutive days; or

                  (ii) a decree or order adjudging the Company to be insolvent,
         or approving a petition seeking reorganization, arrangement, adjustment
         or composition of the Company and such decree or order shall remain
         unstayed and in effect for a period of 60 consecutive days; or

                  (iii) a final and non-appealable order appointing a Custodian
         of the Company or of any substantial part of the property of the
         Company, or ordering the winding up or liquidation of the affairs of
         the Company; or

         (f) the Company pursuant to or within the meaning of any Bankruptcy
Law: (i) commences a voluntary case or proceeding; (ii) consents to the entry of
an order for relief against it in an involuntary case or proceeding; (iii) files
a petition or answer or consent seeking reorganization or relief or consents to
such filing or to the appointment of or taking possession by a Custodian of it
or for all or substantially all of its property, and such Custodian is not
discharged within 60 days; (iv) makes a general assignment for the benefit of
its creditors; or (v) admits in writing its inability to pay its debts generally
as they become due; or

         (g) if applicable, failure by the Company to deliver the required
securities or other rights upon an appropriate conversion or exchange election
by Holders of the Debentures or the related Preferred Securities; or

         (h) any other Event of Default provided in or pursuant to this
Indenture with respect to Debentures of such series.


                                       25
<PAGE>   32
         The term "Bankruptcy Law" means Title 11 of the United States Code, or
any similar federal or state bankruptcy, insolvency, reorganization or other law
for the relief of debtors. "Custodian" means any receiver, trustee, assignee,
liquidator, sequestrator, custodian or similar official under any Bankruptcy
Law.

         A Default under clause (d) above is not an Event of Default until (i)
the Trustee provides a "Notice of Default" to the Company or the Holders of at
least 25% in aggregate principal amount of the Debentures of that series at the
time outstanding or, if that series of Debentures is held by a Trust, the
holders of at least 25% in aggregate liquidation amount of the outstanding
Preferred Securities of that Trust provide a "Notice of Default" to the Company
and the Trustee and (ii) the Company does not cure such Default within the time
specified in clause (d) above after receipt of such notice. Any such notice must
specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default."

SECTION 6.02      ACCELERATION.

         If any Event of Default with respect to the Debentures of any series
other than an Event of Default under clause (e) or (f) of Section 6.01 occurs
and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Debentures of that series then outstanding may declare
the principal of, and any accrued interest on, all the Debentures of that series
due and payable immediately, provided that in the case of a series of Debentures
then held by a Trust, if upon an Event of Default with respect to the Debentures
of that series the Trustee has, or the Holders of at least 25% in aggregate
principal amount of the Debentures of that series then outstanding have, failed
to declare the principal of, and any accrued interest on, the Debentures of that
series to be immediately due and payable, the holders of at least 25% in
aggregate liquidation amount of the outstanding Preferred Securities of that
Trust shall have such right by a notice in writing to the Company and the
Trustee. If an Event of Default specified in clause (e) or (f) of Section 6.01
occurs, the principal of, and any accrued interest on, all the Debentures shall
ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Debentureholders.

         The foregoing paragraph, however, is subject to the condition that if,
at any time after the principal of the Debentures of that series shall have been
so declared due and payable, and before any judgment or decree for the payment
of the moneys due shall have been obtained or entered as hereinafter provided,
the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
all matured installments of interest upon all the Debentures of that series and
the principal of and premium, if any, on all Debentures of that series which
shall have become due otherwise than by acceleration (with interest upon such
principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate accruing on the Debentures of that series to the date of such payment or
deposit) and the amount payable to the Trustee under Section 7.06, and any and
all Defaults under the Indenture, other than the nonpayment of principal of and
interest on Debentures of that series which shall not have become due by their
terms, shall have been remedied or waived as provided in Section 6.04, then and
in every such case the Holders of at least a majority in aggregate principal
amount of the Debentures of that series then outstanding (subject to, in the
case of any series of Debentures held as assets of a Trust and with respect to
which a Security Exchange has not theretofore occurred, such consent of the
holders of the Preferred Securities and the Common Securities of such Trust as
may be required under the Trust Agreement of such Trust), by written notice to
the Company and to the Trustee, may rescind and annul such declaration and its
consequences with respect to 


                                       26
<PAGE>   33
that series of Debentures; but no such rescission and annulment shall extend to
or shall affect any subsequent default, or shall impair any right consequent
thereon.

SECTION 6.03      OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may, in
its own name or as trustee of an express trust, institute, pursue and prosecute
any proceeding, including without limitation, any action at law or suit in
equity or other judicial or administrative proceeding to collect the payment of
principal of or premium, if any, or interest on the Debentures of the series
that is in default, to enforce the performance of any provision of the
Debentures of that series or this Indenture or to obtain any other available
remedy.

         The Trustee may maintain a proceeding even if it does not possess any
of the Debentures or does not produce any of the Debentures in the proceeding. A
delay or omission by the Trustee, any Debentureholder or the holders of
Preferred Securities in exercising any right or remedy accruing upon an Event of
Default shall not impair such right or remedy or constitute a waiver of, or
acquiescence in, such Event of Default. No remedy is exclusive of any other
remedy. All available remedies are cumulative.

SECTION 6.04      WAIVER OF PAST DEFAULTS.

         If a Default or Event of Default with respect to a series of Debentures
has occurred and is continuing, the Holders of at least a majority in aggregate
principal amount of the Debentures of that series at the time outstanding, or,
if that series of Debentures is held by a Trust, the holders of at least a
majority in aggregate liquidation amount of the Preferred Securities of that
Trust, in each case by notice to the Trustee and the Company, may waive an
existing Default or Event of Default and its consequences except a Default or
Event of Default in the payment of the principal of or premium, if any, or
interest on any Debenture of that series (unless such Event of Default has been
cured and a sum sufficient to pay all matured installments of interest and
premium, if any and principal due otherwise than by acceleration has been
deposited with the Trustee) or a default in respect of a covenant or provision
which under this Indenture cannot be modified or amended without the consent of
the holder of each outstanding Debenture of that series. When a Default or Event
of Default is waived, it is deemed cured and shall cease to exist, but no such
waiver shall extend to any subsequent or other Default or Event of Default or
impair any consequent right.

SECTION 6.05      CONTROL BY HOLDERS.

         The Holders of at least a majority in aggregate principal amount of the
Debentures of a series or, if that series of Debentures is held by a Trust, the
holders of at least a majority in aggregate liquidation amount of the Preferred
Securities of that Trust, may direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or of exercising any
trust or power conferred on the Trustee, in respect of such series of
Debentures. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or that the Trustee determines in good
faith is unduly prejudicial to the rights of other Debentureholders or may
involve the Trustee in personal liability. The Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction,
including withholding notice to the Holders of the Debentures of continuing
default (except in the payment of the principal of (other than any mandatory
sinking fund payment) or premium, if any, or 


                                       27
<PAGE>   34
interest on any Debentures) if the Trustee considers it in the interest of the
Holders of the Debentures to do so.

SECTION 6.06      LIMITATION ON SUITS.

         Except as provided in Section 6.07 or 6.08, no Holder of Debentures of
any series or holder of Preferred Securities of the Trust which is the Holder of
that series of Debentures may pursue any remedy with respect to this Indenture
or the Debentures unless:

         (a) the Holders of Debentures of such series or the holders of such
Preferred Securities give to the Trustee written notice stating that an Event of
Default with respect to the corresponding Debentures of such series has occurred
and is continuing;

         (b) the Holders of at least 25% in aggregate principal amount of the
outstanding Debentures of that series or the holders of at least 25% in
aggregate liquidation amount of such Preferred Securities make a written request
to the Trustee to pursue a remedy;

         (c) the Holders of Debentures of such series or the holders of such
Preferred Securities provide to the Trustee reasonable security and indemnity
against any loss, liability or expense satisfactory to the Trustee;

         (d) the Trustee does not comply with the request within 60 days after
receipt of the notice, the request and the offer of security and indemnity; and

         (e) during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Debentures of that series or the holders of at
least a majority in aggregate liquidation amount of such Preferred Securities do
not give the Trustee a direction inconsistent with the request,

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

SECTION 6.07      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM 
                  AND INTEREST.

         Notwithstanding any other provision of this Indenture, the Holder of
any Debenture shall have the right which is absolute and unconditional to
receive payment of the principal of, premium, if any, and (subject to Section
2.02) interest on such Debenture on the respective due dates expressed in such
Debenture (or, in the case of redemption, on the Redemption Date) and to convert
or exchange such Debentures in accordance with its terms, if applicable, and to
institute suit for the enforcement of such payment or conversion or exchange,
and such right shall not be impaired without the consent of such Holder.


                                       28
<PAGE>   35
SECTION 6.08      DIRECT ACTION RIGHT OF HOLDERS OF TRUST PREFERRED SECURITIES.

         If an Event of Default has occurred and is continuing and is
attributable either to (a) the failure of the Company to pay the principal of or
premium, if any, or interest on the Debentures on the due date therefor or (b)
the failure by the Company to deliver the required securities or other rights
upon an appropriate conversion or exchange right election, and an event of
default has occurred and is continuing under the applicable Trust Agreement, a
holder of the related Preferred Securities, in lieu of any action that may
otherwise be taken hereunder as a Holder of Debentures, may institute a legal
proceeding directly against the Company for enforcement of payment to such
holder of the principal of or premium, if any, or interest on such Debentures
having a principal amount equal to the liquidation amount of the Preferred
Securities held by such holder or for enforcement of such conversion or exchange
rights, as the case may be (a "Direct Action"). Notwithstanding anything
contained herein to the contrary, the Company may not amend this Indenture to
remove the foregoing right to bring a Direct Action without the prior written
consent of the holders of all of the Preferred Securities outstanding.
Notwithstanding any payments made to a holder of Preferred Securities by the
Company in connection with a Direct Action, the Company shall remain obligated
to pay the principal of and premium, if any, or interest on the related
Debentures, 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.

SECTION 6.09      COLLECTION SUITS BY THE TRUSTEE.

         The Company covenants that if

         (a) default is made in the payment of any interest on any Debenture
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 or premium, if
any, on any Debenture on the Stated Maturity Date or Redemption Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holder of such Debenture, the whole amount then due and payable on such
Debenture for principal, premium, if any, and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium, if any, and on any overdue interest, at the rate or rates
prescribed therefor in such Debenture 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 the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Debenture and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Debenture, wherever
situated.

         If an Event of Default with respect to Debentures of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of 


                                       29
<PAGE>   36
Debentures of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or such Debentures or in aid of the exercise of any power granted
herein, or to enforce any other remedy available under this Indenture or by law.

SECTION 6.10      TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or its properties or assets, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise:

         (a) to file and prove a claim for the whole amount of the principal of
and premium, if any, and interest on the Debentures and to file such other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and of the
Holders of Debentures allowed in such judicial proceeding; and

         (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any Custodian 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 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 7.06.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a
Debenture any plan of reorganization, arrangement, adjustment or composition
affecting the Debentures 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 6.11      PRIORITIES.

         If the Trustee collects any money pursuant to this Article 6, it shall,
subject to Article 10, pay out the money in the following order:

         FIRST:            to the Trustee for amounts due under Section 7.06;

         SECOND:           to Holders of Debentures in respect of which or for
                           the benefit of which such money has been collected
                           for amounts due and unpaid on such Debentures for the
                           principal thereof or premium, if any, or interest, if
                           any, thereon ratably, without preference or priority
                           of any kind, according to such amounts due and
                           payable on such Debentures; and

         THIRD:            the balance, if any, to the Company.

         Except as otherwise set forth in the Debentures, the Trustee may fix a
Record Date and payment date for any payment to Debentureholders pursuant to
this Section.

SECTION 6.12      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 or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant (other than the Trustee) in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section does not apply to a suit by
the Trustee, a suit by a Holder of Debentures or holder of Preferred Securities
pursuant to Section 6.07 or 6.08 or a suit by Holders of Debentures of more than
10% in aggregate principal amount of the outstanding Debentures of any series
or, if a series of Debentures is held by a Trust, the holders of more than 10%
in aggregate liquidation amount of the Preferred Securities of that Trust.


                                    ARTICLE 7
                                   THE TRUSTEE

SECTION 7.01      DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

         (a) If an Event of Default occurs and is continuing with respect to the
Debentures of any series, the Trustee shall exercise the rights and powers
vested in it by this Indenture with respect to that series and use the same
degree of care and skill in its exercise as a prudent person would exercise or
use under the circumstances in the conduct of his or her own affairs.

         (b) Except during the continuance of an Event of Default with respect
to the Debentures of any series, (i) the Trustee need perform only those duties
with respect to that series that are specifically set forth in this Indenture or
the TIA and no others; and (ii) in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of any certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall examine the certificates and opinions to determine whether or not they
conform to the requirements of this Indenture (but shall not be required to
confirm or investigate the accuracy of mathematical calculations or other facts
stated therein).

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

               (i) this clause (c) does not limit the effect of Section 7.01(b);

              (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts; and

             (iii) the Trustee shall not be liable with respect to any action it
         takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.


                                       31
<PAGE>   38
         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to Section 7.01(a), (b), (c) and (e) and Section 7.02.

         (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives security and indemnity reasonably satisfactory to it
against any loss, liability or expense (including reasonable counsel fees).

         (f) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur personal 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.

         (g) Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall not be
liable for interest on any money held by it hereunder except as otherwise agreed
with the Company.

SECTION 7.02      RIGHTS OF THE TRUSTEE.

         Subject to Sections 315(a) through 315(d) of the TIA:

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

         (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Order (in each case, other than delivery of
any Debenture to the Trustee for authentication and delivery pursuant to Section
2.03 which shall be sufficiently evidenced as provided therein) and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;

         (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
shall 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 and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon;

         (e) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by or pursuant to this Indenture at the request or
direction of any of the Holders of Debentures of any series pursuant to this
Indenture, unless such Holders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;


                                       32
<PAGE>   39
         (f) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
coupon or other paper or document, but the Trustee, in its discretion, may make
such further inquiry or investigation into such facts or matters as it may see
fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine, during business hours and upon
reasonable notice, the books, records and premises of the Company, personally or
by agent or attorney; and

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

SECTION 7.03      NOT RESPONSIBLE FOR RECITALS OR ISSUANCES OF DEBENTURES.

         The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Debentures. The Trustee shall not be accountable for the
Company's use of the proceeds from the Debentures, and the Trustee shall not be
responsible for any statement in this Indenture or the Debentures or any report
or certificate issued by the Company hereunder or any registration statement
relating to the Debentures (other than the Trustee's Certificate of
Authentication and the Trustee's Statement of Eligibility on Form T-1), or the
determination as to which beneficial owners are entitled to receive any notices
hereunder.

SECTION 7.04      NOTICE OF DEFAULTS.

         If a Default occurs and is continuing with respect to the Debentures of
any series and if it is known to the Trustee, the Trustee shall mail to each
Holder of a Debenture of that series notice of the Default within 90 days after
it becomes known to the Trustee unless such Default shall have been cured or
waived. Except in the case of a Default described in Section 6.01(a), (b) or
(g), the Trustee may withhold such notice if and so long as a committee of
Responsible Officers in good faith determines that the withholding of such
notice is in the interests of the Holders of the Debentures of that series. The
Trustee shall not be charged with knowledge of any Default unless a Responsible
Officer assigned to the Corporate Trust Department of the Trustee shall have
actual knowledge of the Default. The second sentence of this Section shall be in
lieu of the proviso to TIA Section 315(b). Said proviso is hereby expressly
excluded from this Indenture, as permitted by the TIA.

SECTION 7.05      REPORTS BY TRUSTEE TO HOLDERS.

         Within 60 days after each September 1, beginning with the September 1
next following the date of this Indenture, the Trustee shall mail to each
Debentureholder, and such other holders that have submitted their names to the
Trustee for such purpose, a brief report dated as of such September 1 in
accordance with and to the extent required under TIA Section 313.

         A copy of each report at the time of its mailing to Debentureholders
shall be filed with the Company, the SEC and any securities exchange on which
the Debentures are listed. The Company agrees to promptly notify the Trustee
whenever the Debentures become listed on any securities exchange and of any
listing thereof.

SECTION 7.06      COMPENSATION AND INDEMNITY.

         The Company covenants and agrees:

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

         (b) to reimburse the Trustee upon its request for reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses, and advances of its agents and counsel; provided that, prior to any
Default or Event of Default, the Trustee shall only have one outside counsel),
including all reasonable expenses and advances incurred or made by the Trustee
in connection with any Default or Event of Default or any membership on any
creditors' committee, except any such expense or advance as may be attributable
to its negligence or bad faith; and

         (c) to indemnify the Trustee, its officers, employees, directors and
shareholders, for, and to hold it harmless against, any and all loss, liability
or expense, incurred without negligence or willful misconduct on its part,
arising out of or in connection with the acceptance or administration of this
trust, including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder.

         Before, after or during an Event of Default with respect to the
Debentures of a series, the Trustee shall have a claim and lien prior to the
Debentures of that series as to all property and funds held by it hereunder for
any amount owing it for its fees and expenses or any predecessor Trustee
pursuant to this Section, except with respect to funds held by the Trustee or
any Paying Agent in trust for the payment of principal of or premium, if any, or
interest on Debentures pursuant to Section 2.05 or Section 8.01.

         The Company's payment and indemnity obligations pursuant to this
Section are not subject to Article 10 of this Indenture and shall survive the
discharge of this Indenture. When the Trustee renders services or incurs
expenses after the occurrence of a Default specified in Section 6.01, the
compensation for services and expenses are intended to constitute expenses of
administration under any Bankruptcy Law.

SECTION 7.07      ELIGIBILITY; DISQUALIFICATION.

         (a) The Trustee shall at all times satisfy the requirements of the TIA
Sections 310(a)(1) and 310(a)(2). The Trustee (or any Affiliate thereof which
has unconditionally guaranteed the obligations of the Trustee hereunder) shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recently published annual report of condition. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

         (b) The Trustee shall comply with TIA Section 310(b). In determining
whether the Trustee has conflicting interests as defined in TIA Section
310(b)(1), the provisions contained in the proviso to TIA Section 310(b)(1) and
the Trustee's Statement of Eligibility on Form T-1 shall be deemed incorporated
herein.

SECTION 7.08      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 7.09.

         (b) The Trustee may resign at any time with respect to the Debentures
of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 7.09 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Debentures of such series.

         (c) If the Trustee has or shall acquire any conflicting interest, as
defined in Section 310(b) of the TIA, with respect to the Debentures of any
series, it shall, within 90 days after ascertaining it has such conflicting
interest, either eliminate the conflicting interest or resign with respect to
the Debentures of that series in the manner set forth in this Section.

         (d) The Trustee may be removed at any time with respect to the
Debentures of any series by Act of the Holders of at least a majority in
principal amount of the outstanding Debentures of such series, delivered to the
Trustee and to the Company.

         (e) If at any time:

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

                  (ii) the Trustee shall cease to be eligible under Section
         7.07(a) 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 bankrupt or insolvent, or a receiver of Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation, then, in any such case,
         (1) the Company by a Board Resolution may remove the Trustee with
         respect to all Debentures, or (2) subject to Section 6.12, any Holder
         of a Debenture who has been a bona fide Holder of a Debenture for at
         least six months may, on behalf of himself and all others similarly
         situated, petition any court of competent jurisdiction for the removal
         of the Trustee with respect to all Debentures of such series and the
         appointment of a successor Trustee or Trustees.

         (f) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debentures of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Debentures of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Debentures of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Debentures of any particular series) and shall comply with
the applicable requirements of Section 7.09. If, within one year after such


                                       35
<PAGE>   42
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Debentures of any series shall be
appointed by Act of the Holders of at least a majority in principal amount of
the outstanding Debentures of such series, notice of such appointment shall be
delivered to the Company and the retiring Trustee. The successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 7.09, become the successor Trustee
with respect to the Debentures of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Debentures of any series shall have been so appointed by the Company or
the Holders of Debentures and accepted appointment in the manner required by
Section 7.09, any Holder of a Debenture who has been a bona fide Holder of a
Debenture of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Debentures of such
series.

         (g) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Debentures of any series and each appointment
of a successor Trustee with respect to the Debentures of any series in the
manner provided in Section 13.02. Each notice shall include the name of the
successor Trustee with respect to the Debentures of such series and the address
of its Corporate Trust Office.

SECTION 7.09      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Debentures, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Debentures of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Debentures of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (i) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and deeds of the Trustee with respect to the Debentures of that or those
series which the appointment of such successor Trustee relates, (ii) if the
retiring Trustee is not retiring with respect to all Debentures, shall contain
such provisions as shall be deemed necessary or desirable to confirm that all
the rights, powers, trusts and duties of the retiring Trustee with respect to
the Debentures of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (iii) shall
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees as co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture
the resignation or removal of the


                                       36
<PAGE>   43
retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Debentures of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Debentures of that or those series to
which the appointment of such successor Trustee relates.

         (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

         (d) 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 7.10      SUCCESSOR TRUSTEE BY MERGER.

         If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all its corporate trust business or assets to another
corporation, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

satisfaction and discharge of this Indenture as to such series, when

                  series which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 2.08, and
                  (2) Debentures of such series for whose payment money has
                  theretofore been deposited in trust or segregated and held in

                  discharged from such trust, as provided in Section 8.04) have
                  been delivered to the Trustee for cancellation; or

                  in an interest bearing account insured by the Federal Deposit
                  Insurance Corporation) in an amount, or (b) U.S. Government
                  Obligations, maturing as to principal and interest at such
                  times and in such amounts as will ensure the availability of
                  cash, or (c) a combination thereof, in an amount sufficient to
                  pay and discharge the entire indebtedness on such Debentures
                  not theretofore delivered to the Trustee for cancellation,
                  including the principal of, and premium, if any, and interest
                  on such Debentures, to the date of such deposit (in the case
                  of Debentures which have become due and payable) or to the
                  Stated Maturity Date or Redemption Date thereof, as the case
                  may be; and

         (b) the Company has paid or caused to be paid all other sums payable
hereunder by the Company with respect to the outstanding Debentures of such
series.

         In the event there are Debentures of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Debentures of such series as to which it is Trustee and if the other conditions
thereto are met.

         Notwithstanding the satisfaction and discharge of this Indenture, with
respect to any series of Debentures, the obligations of the Company to the
Trustee under Section 7.06 and, if money shall have been deposited with the
Trustee pursuant to clause (a)(ii) of this Section, the following obligations of
the Company and the Trustee with respect to the Debentures of such series, shall
survive: (i) the rights of registration of transfer and exchange of Debentures
of such series, (ii) the replacement of apparently mutilated, defaced,
destroyed, lost or stolen Debentures of such series, (iii) the rights of the
Holders of the Debentures of such series to receive payments of the principal of
and premium, if any, interest on the Debentures of such series, (iv) the rights
of the Holders of the Debentures of such series as beneficiaries hereof with
respect to the property so deposited with the Trustee payable to all or any of
them, (v) the obligation of the Company to maintain an Office or Agency for
payments on and registration of transfer of the Debentures of such series, (vi)
the rights, obligations and immunities of the Trustee hereunder, and (vii) any
rights to convert or exchange the Debentures of such series into other
securities or rights in accordance with their terms.

SECTION 8.02      APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT OF 
                  DEBENTURES.

         Subject to Section 8.04, all moneys deposited with the Trustee pursuant
to Section 8.01 shall be held in trust and applied by it to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent), to the Holders of the Debentures of the series for the payment


                                       38
<PAGE>   45
or redemption of which such moneys have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest, but such money
need not be segregated from other funds except to the extent required by law.

SECTION 8.03      REPAYMENT OF MONEYS HELD BY PAYING AGENT.

         In connection with the satisfaction and discharge of this Indenture,
all moneys then held by any Paying Agent under this Indenture shall, upon demand
of the Company, be repaid to it or paid to the Trustee, and thereupon such
Paying Agent shall be released from all further liability with respect to such
moneys.

SECTION 8.04      RETURN OF MONEYS HELD BY THE TRUSTEE AND PAYING AGENT 
                  UNCLAIMED FOR TWO YEARS.

         Any moneys deposited with or paid to the Trustee or any Paying Agent
for the payment of the principal of and premium, if any, or interest on the
Debentures of any series and not applied but remaining unclaimed for two years
after the date when such principal, premium, if any, or interest shall have
become due and payable shall, unless otherwise required by mandatory provisions
of applicable escheat or abandoned or unclaimed property law, be repaid to the
Company by the Trustee or such Paying Agent, and the Holders of such Debentures
shall, unless otherwise required by mandatory provisions of applicable escheat
or abandoned or unclaimed property laws, thereafter look only to the Company for
any payment which such Holder may be entitled to collect as a general unsecured
creditor, and all liability of the Trustee or any Paying Agent with respect to
such moneys shall thereupon cease.

                             SUPPLEMENTAL INDENTURES

SECTION 9.01      SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

         From time to time, when authorized by a resolution of the Board of
Directors, the Company and the Trustee, without notice to or the consent of any
Holders of the Debentures, may amend or supplement this Indenture:

         (a) to evidence the succession of another Person to the Company and the
assumption by any such successor of the covenants of the Company contained
herein and in the Debentures; or

         (b) to add to the covenants of the Company for the benefit of the
Holders of all or any series of Debentures (as shall be specified in such
supplemental indenture or indentures) or to surrender any right or power herein
conferred upon the Company; provided, however, that in respect of any such
additional covenant, or restriction or condition on the Company, such
supplemental indenture may provide for a particular period of grace after
default (which period may be shorter or longer than that allowed in the case of
other defaults) or may provide for an immediate enforcement upon such default or
may limit the remedies available to the Trustee upon such default; or

         (c) to add any additional Events of Default with respect to all or any
series of Debentures (as shall be specified in such supplemental indenture); or


                                       39
<PAGE>   46
         (d) to change or eliminate any of the provisions of this Indenture,
provided, that any such change or elimination shall become effective only when
there is no Debenture outstanding of any series created prior to the execution
of such supplemental indenture which is entitled to the benefit of such
provision; or

         (e) to establish the form or terms of Debentures of any series as
permitted by Section 2.01 or, in lieu of any such supplemental indenture, the
Company may provide the Trustee with an Officers' Certificate with respect to
the form or terms of such Debentures; or

         (f) to evidence and provide for the acceptance of appointment hereunder
by a successor Trustee with respect to the Debentures of one or more series, and
to add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee; or

         (g) to cure any ambiguity, to correct or supplement any provision
herein or in any supplemental indenture which may be defective or inconsistent
with any other provision herein or in any supplemental indenture, or to make any
other provisions with respect to matters or questions arising under this
Indenture, which shall not adversely affect the interests of the Holders of
Debentures of any series then outstanding in any material respect; or

         (h) to add to, delete from or revise the conditions, limitations and
restrictions on the authorized amount, terms or purposes of issue,
authentication and delivery of Debentures as herein set forth; or

         (i) to maintain qualification of this Indenture under the TIA; or

         (j) to supplement any of the provisions of this Indenture to such
extent as shall be necessary to permit or facilitate the defeasance and
discharge of any series of Debentures provided that any such action shall not
adversely affect the interests of any Holder of a Debenture of such series or
any other Debenture in any material respect.

SECTION 9.02      SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         The Company and the Trustee may amend this Indenture in any manner not
permitted by Section 9.01 or may waive future compliance by the Company with any
provisions of this Indenture with the consent of the Holders of at least a
majority in aggregate principal amount of the Debentures of each series affected
thereby then outstanding (and, in the case of any series of Debentures held as
assets of a Trust and with respect to which a Security Exchange has not
theretofore occurred, such consent of holders of the Preferred Securities and
the Common Securities of such Trust as may be required under the Trust Agreement
of such Trust). Such an amendment or waiver may not, without the consent of each
Holder of any Debenture affected thereby:

         (a) reduce the principal amount of such Debentures;

         (b) reduce the percentage of the principal amount of such Debentures
the Holders of which must consent to an amendment of this Indenture or a waiver;


                                       40
<PAGE>   47
         (c) change (i) the stated maturity of the principal of or the interest
on such Debentures, except in connection with any Extension Period, (ii) the
rate of interest (or the manner of calculation thereof) on such Debentures, or
(iii) the duration of the maximum consecutive period that payments of interest
on such Debentures may be deferred;

         (d) change adversely to the Holders the redemption, conversion or
exchange provisions applicable to such Debentures, if any;

         (e) change the currency in respect of which the payments on such
Debentures are to be made;

         (f) make any change in Article 10 that adversely affects the rights of
the Holders of the Debentures or any change to any other Section hereof that
adversely affects their rights under Article 10; or

         (g) change Section 6.07 or 6.08;

provided that, in the case of the outstanding Debentures of a series then held
by a Trust, no such amendment shall be made that adversely affects the holders
of the Preferred Securities of that Trust, and no waiver of any Event of Default
with respect to the Debentures of that series or compliance with any covenant
under this Indenture shall be effective, without the prior consent of the
holders of at least a majority of the aggregate liquidation amount of the
outstanding Preferred Securities of that Trust or the holder of each such
Preferred Security, as applicable.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Debentures, or which modifies
the rights of the Holders of Debentures of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Debentures of any other series.

         It shall not be necessary for the consent of the Holders of Debentures
or holders of Preferred Securities under this Section to approve the particular
form of any proposed amendment, but it shall be sufficient if such consent
approves the substance thereof.

         If certain Holders agree to defer or waive certain obligations of the
Company hereunder with respect to Debentures held by them, such deferral or
waiver shall not affect the rights of any other Holder to receive the payment or
performance required hereunder in a timely manner.

         After an amendment or waiver under this Section becomes effective, the
Company shall mail to each Holder a notice briefly describing the amendment or
waiver. Any failure of the Company to mail such notices, or any defect therein,
shall not, however, in any way impair or affect the validity of such amendment
or waiver.

SECTION 9.03      COMPLIANCE WITH TRUST INDENTURE ACT.

         Every supplemental indenture executed pursuant to this Article 9 shall
comply with the TIA.

SECTION 9.04      REVOCATION AND EFFECT OF CONSENTS, WAIVERS AND ACTIONS.

         Until an amendment, waiver or other action by Holders becomes
effective, a consent, waiver or any other action by a Holder of a Debenture
hereunder is a continuing consent by the Holder and every subsequent Holder of
that Debenture or portion of the Debenture that evidences the same obligation as
the consenting Holder's Debenture, even if notation of the consent, waiver or
action is not made on such Debenture. However, any such Holder or subsequent
Holder may revoke the consent, waiver or action as to such Holder's Debenture or
portion of the Debenture if the Trustee receives the notice of revocation before
the consent of the requisite aggregate principal amount of such Debentures then
outstanding has been obtained and not revoked. After an amendment, waiver or
action becomes effective, it shall bind every Holder of the Debentures of the
related series, except as provided in Section 9.02.

         The Company may, but shall not be obligated to, fix a Record Date for
the purpose of determining the Persons entitled to consent to any amendment or
waiver. If a Record Date is fixed, then, notwithstanding the first two sentences
of the immediately preceding paragraph, only Holders of Debentures or holders of
Preferred Securities, as applicable, on such Record Date or their duly
designated proxies, and only those Persons, shall be entitled to consent to such
amendment, supplement or waiver or to revoke any consent previously given,
whether or not such Persons continue to be such after such Record Date. No such
consent shall be valid or effective for more than 90 days after such Record
Date.

SECTION 9.05      NOTATION ON OR EXCHANGE OF DEBENTURES.

         Debentures of the related series authenticated and made available for
delivery after the execution of any supplemental indenture pursuant to this
Article 9 may, and shall, if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Debentures so modified to
conform, in the opinion of the Trustee and the Board of Directors, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and made available for delivery by the Trustee in exchange for
outstanding Debentures.

SECTION 9.06      EXECUTION OF SUPPLEMENTAL INDENTURES.

         The Trustee shall execute any supplemental indenture authorized
pursuant to this Article 9 if the supplemental indenture does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, execute it. In executing such supplemental
indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Officers' Certificate and Opinion of Counsel
stating that such supplemental indenture is authorized or permitted by this
Indenture.

SECTION 9.07      EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article 9,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes and every Holder
of Debentures of the related series theretofore or thereafter authenticated and
made available for delivery hereunder shall be bound thereby.

                                  SUBORDINATION

SECTION 10.01     DEBENTURES SUBORDINATED TO SENIOR INDEBTEDNESS.

         Notwithstanding the provisions of Section 6.11 or any other provision
herein or in any Debenture, the Company and the Trustee and, by their acceptance
thereof, the Holders of the Debentures (a) covenant and agree that all payments
by the Company of the principal of and premium, if any, and interest on the
Debentures (other than Debentures which have been discharged pursuant to Article
8) shall be subordinated in accordance with the provisions of this Article 10 to
the prior payment in full, in cash or cash equivalents, of all amounts payable
on, under or in connection with Senior Indebtedness, and (b) acknowledge that
holders of Senior Indebtedness are or shall be relying on this Article 10.
Nothing herein or in any Debenture is intended to or shall limit the amount of
Senior Indebtedness the Company may incur.

SECTION 10.02     PRIORITY AND PAYMENT OF PROCEEDS IN CERTAIN EVENTS: REMEDIES
                  STANDSTILL.

         (a) Upon any payment or distribution of assets or securities of the
Company, as the case may be, of any kind or character, whether in cash, property
or securities, upon any dissolution or winding up or total or partial
liquidation or reorganization of the Company, whether voluntary or involuntary,
or in bankruptcy, insolvency, receivership or other proceedings, all amounts
payable on, under or in connection with Senior Indebtedness (including any
interest accruing on such Senior Indebtedness subsequent to the commencement of
a bankruptcy, insolvency, receivership or similar proceeding) shall first be
paid in full in cash, or payment provided for in cash or cash equivalents,
before the Holders or the Trustee on behalf of the Holders or the holders of
Preferred Securities shall be entitled to receive from the Company any payment
of principal of or premium, if any, or interest on the Debentures or
distribution of any assets or securities.

         (b) No direct or indirect payment by or on behalf of the Company of
principal of or premium, if any, or interest on the Debentures (other than
Debentures which have been discharged pursuant to Article 8), whether pursuant
to the terms of the Debentures or upon acceleration or otherwise, shall be made
if, at the time of such payment, there exists (i) a default in the payment of
all or any portion of any Senior Indebtedness and the Trustee has received
written notice thereof from the Company, from holders of Senior Indebtedness or
from any trustee, representative or agent therefor, or (ii) any other default
affecting Senior Indebtedness as a result of which the maturity of Senior
Indebtedness has been accelerated and the Trustee has received written notice
from the Company, from holders of Senior Indebtedness or from any trustee,
representative or agent therefor, and such default shall not have been cured or
waived by or on behalf of the holders of such Senior Indebtedness.


                                       43
<PAGE>   50
         (c) If, notwithstanding the foregoing provisions prohibiting such
payment or distribution, the Trustee or any Holder shall have received any
payment on account of the principal of or premium, if any, or interest on the
Debentures when such payment is prohibited by this Section and before all
amounts payable on, under or in connection with Senior Indebtedness are paid in
full in cash or cash equivalents, then and in such event (subject to the
provisions of Section 10.08) such payment or distribution shall be received and
held in trust for the holders of Senior Indebtedness and, at the written
direction of the trustee, representative or agent for the holders of the Senior
Indebtedness, shall be paid to the holders of the Senior Indebtedness remaining
unpaid to the extent necessary to pay such Senior Indebtedness in full in cash
or cash equivalents.

         Upon any payment or distribution of assets or securities referred to in
this Article 10, the Trustee and the Holders shall be entitled to rely upon any
order or decree of a court of competent jurisdiction in which such dissolution,
winding up, liquidation or reorganization proceedings are pending, and upon a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other Person making any such payment or distribution, delivered to the
Trustee for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of Senior Indebtedness and other Indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
10.

SECTION 10.03     PAYMENTS WHICH MAY BE MADE PRIOR TO NOTICE.

         Nothing in this Article 10 or elsewhere in this Indenture shall prevent
(a) the Company, except under the conditions described in Section 10.02, from
making payments of principal of or premium, if any, or interest on the
Debentures or from depositing with the Trustee any monies for such payments, or
(b) the application by the Trustee of any monies deposited with it for the
purpose of making such payments of principal of or premium, if any, or interest
on the Debentures, to the Holders entitled thereto, unless at least one Business
Day prior to the date when such payment would otherwise (except for the
prohibitions contained in Section 10.02) become due and payable, the Trustee
shall have received the written notice provided for in Section 10.02(b)(i) or
(ii).

SECTION 10.04     RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS NOT TO BE IMPAIRED.

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

         The provisions of this Article 10 are intended to be for the benefit
of, and shall be enforceable directly by, the holders of Senior Indebtedness.
Notwithstanding anything to the contrary in this Article 10, to the extent any
Holders or the Trustee have paid over or delivered to any holder of Senior
Indebtedness any payment or distribution received on account of the principal of
or premium, if any, or interest on the Debentures to which any other holder of
Senior Indebtedness shall be entitled to share in accordance with Section 10.02,
no holder of Senior Indebtedness shall have a claim or right against any Holders
or the Trustee with respect to any such payment or distribution or as a result
of the failure to make payments or distributions to such other holder of Senior
Indebtedness.

<PAGE>   51
SECTION 10.05     TRUSTEE MAY TAKE ACTION TO EFFECTUATE SUBORDINATION.

         Each Holder of a Debenture, by his acceptance thereof, authorizes and
directs the Trustee on his behalf to take such action as may be required by the
trustee, representative or agent for holders of Senior Indebtedness or by the
Company to effectuate, as between the holders of Senior Indebtedness and the
Holders, the subordination as provided in this Article 10 and appoints the
Trustee his attorney-in-fact for any and all such purposes.

SECTION 10.06     SUBROGATION.

         Upon the payment in full, in cash or cash equivalents, of all Senior
Indebtedness, any Holder shall be subrogated to the rights of the holders of
such Senior Indebtedness to receive payments or distributions of assets of the
Company in respect of such Senior Indebtedness until the Debentures shall be
paid in full; and for the purposes of such subrogation, no payments or
distributions to holders of such Senior Indebtedness of any cash property or
securities to which such Holders of the Debentures would be entitled except for
this Article 10, and no payment pursuant to this Article 10 to holders of such
Senior Indebtedness by such Holders of the Debentures, shall, as between the
Company, its creditors other than holders of such Senior Indebtedness and such
Holders of the Debentures, be deemed to be a payment by the Company to or on
account of such Senior Indebtedness, it being understood that the provisions of
this Article 10 are solely for the purpose of defining the relative rights of
the holders of such Senior Indebtedness, on the one hand, and such Holders of
the Debentures, on the other hand.

         If any payment or distribution to which Holders of Debentures would
otherwise have been entitled but for the provisions of this Article 10 shall
have been applied, pursuant to this Article 10, to the payment of all Senior
Indebtedness, then and in such case such Holders of the Debentures shall be
entitled to receive from the holders of such Senior Indebtedness at the time
outstanding any payments or distributions received by such holders of Senior
Indebtedness in excess of the amount sufficient to pay, in cash or cash
equivalents, all such Senior Indebtedness in full.

SECTION 10.07     OBLIGATIONS OF COMPANY UNCONDITIONAL; REINSTATEMENT.

         Nothing in this Article 10 or elsewhere in this Indenture or in any
Debenture is intended to or shall impair, as between the Company and Holders of
the Debentures, the obligations of the Company, which are absolute and
unconditional, to pay to such Holders the principal of and premium, if any, and
interest on the Debentures 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 such Holders of the Debentures and creditors of the Company other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or any Holder of Debentures or holder of Preferred
Securities, as applicable, from exercising all remedies otherwise permitted by
applicable law under this Indenture, subject to the rights, if any, under this
Article 10 of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy.

         The failure to make a scheduled payment of principal of or premium, if
any, or interest on the Debentures by reason of Section 10.02 shall not be
construed as preventing the occurrence of a Default or an Event of Default under
Section 6.01; provided, however, that if (a) the conditions preventing the
making of such payment no longer exist, and (b) such Holders of the Debentures
are made whole with respect to such omitted payments, the Default or Event of
Default relating thereto (including any failure 


                                       45
<PAGE>   52
to pay any accelerated amounts) shall be automatically waived, and the
provisions of the Indenture shall be reinstated as if no such Event of Default
had occurred.

SECTION 10.08     TRUSTEE ENTITLED TO ASSUME PAYMENTS NOT PROHIBITED IN ABSENCE
                  OF NOTICE.

         The Trustee or Paying Agent shall not be charged with the knowledge of
the existence of any default in the payment of all or a portion of any Senior
Indebtedness or any other default affecting Senior Indebtedness as a result of
which the maturity of the Senior Indebtedness has been accelerated, unless and
until the Trustee or Paying Agent shall have received written notice thereof;
from the Company or one or more holders of Senior Indebtedness or from any
trustee, representative or agent therefor; and, prior to the receipt of any such
written notice, the Trustee or Paying Agent may conclusively assume that no such
facts exist.

         Unless at least two Business Days prior to the date when by the terms
of this Indenture any monies are to be deposited by the Company with the Trustee
or any Paying Agent for any purpose (including, without limitation, the payment
of the principal of or premium, if any, or interest on any Debenture), the
Trustee or Paying Agent shall have received with respect to such monies the
notice provided for in Section 10.02, the Trustee or Paying Agent shall have
full power and authority to receive and apply such monies to the purpose for
which they were received. Neither of them shall be affected by any notice to the
contrary, which may be received by either on or after such second Business Day.
The foregoing shall not apply to the Paying Agent if the Company is acting as
Paying Agent. Nothing in this Section shall limit the right of the holders of
Senior Indebtedness to recover payments as contemplated by Section 10.02. The
Trustee or Paying Agent shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or itself to be a holder of such
Senior Indebtedness (or a trustee, representative or agent on behalf of such
holder) to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee, representative or agent on behalf of any such holder.
The Trustee shall not be deemed to have any duty to the holders (and shall be
fully protected in relying upon such notice) of Senior Indebtedness.

SECTION 10.09     RIGHT OF TRUSTEE TO HOLD SENIOR INDEBTEDNESS.

         The Trustee and any Paying Agent shall be entitled to all of the rights
set forth in this Article 10 in respect of any Senior Indebtedness at any time
held by them to the same extent as any other holder of such Senior Indebtedness,
and nothing in this Indenture shall be construed to deprive the Trustee or any
Paying Agent of any of its rights as such holder.

SECTION 11.01     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Debentures of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Debenture of such series issued
pursuant to this Indenture.


                                       46

         The minimum amount of any sinking fund payment provided for by the
terms of Debentures of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Debentures of such series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Debentures of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 11.02. Each sinking fund payment shall be applied to the
redemption of Debentures of any series as provided for by the terms of
Debentures of such series and this Indenture.

SECTION 11.02     SATISFACTION OF SINKING FUND PAYMENTS WITH DEBENTURES.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Debentures of any series to be made pursuant to the
terms of such Debentures (a) deliver outstanding Debentures of such series
(other than any of such Debentures previously called for redemption or any of
such Debentures in respect of which cash shall have been released to the
Company), and (b) apply as a credit Debentures of such series which have been
redeemed either at the election of the Company pursuant to the terms of such
series of Debentures or through the application of permitted optional sinking
fund payments pursuant to the terms of such Debentures, provided that such
series of Debentures have not been previously so credited. Such Debentures shall
be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Debentures for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.
If as a result of the delivery or credit of Debentures of any series in lieu of
cash payments pursuant to this Section, the principal amount of Debentures of
such series to be redeemed in order to exhaust the aforesaid cash payment shall
be less than $100,000, the Trustee need not call Debentures of such series for
redemption, except upon a Company Order, and such cash payment shall be held by
the Trustee or a Paying Agent and applied to the next succeeding sinking fund
payment on Debentures of such series, provided, however, that the Trustee or
such Paying Agent shall at the request of the Company from time to time pay over
and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Debentures of that
series purchased by the Company having an unpaid principal amount equal to the
cash payment requested to be released to the Company.

SECTION 11.03     REDEMPTION OF DEBENTURES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Debentures, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Debentures of that series pursuant to Section 11.02, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Debentures to be so credited and not
theretofore delivered. If such Officers' Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 30 days before each such sinking fund payment date the Trustee
shall select the Debentures to be redeemed upon such sinking fund payment date
in the manner specified in Section 3.02 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 3.03. Such notice having been duly given, the
redemption of such Debentures shall be made upon the terms and in the manner
stated in Sections 3.04 and 3.06.

of the Holders of such specified percentage in principal amount of the
outstanding Debentures of such series.

         Any resolution passed or decision taken at any meeting of Holders of
Debentures of any series duly held in accordance with this Section shall be
binding on all the Holders of Debentures of such series, whether or not such
Holders were present or represented at the meeting.

                  MEETINGS.

         (a) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Debentures of a series in regard to proof of the holding of
Debentures of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Debentures shall be proved in the manner specified in Section 1.05 and the
appointment of any proxy shall be proved in the manner specified in Section
1.05. Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof
specified in Section 1.05 or other proof.

         (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Debentures as provided in Section 12.02(b), in which
case the Company or the Holders of Debentures of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote at least a majority in principal amount of

         (c) At any meeting each Holder of a Debenture of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
outstanding Debentures of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any

except as a Holder of a Debenture of such series or proxy.

         (d) Any meeting of Holders of Debentures of any series duly called
pursuant to Section 12.02 at which a quorum is present may be adjourned from

SECTION 12.06     COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

Debentures of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Debentures of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the outstanding Debentures of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Debentures of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 12.02 and, if
applicable, Section 12.04. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

          (b) The Subordinated Notes may be transferred or exchanged only in
minimum denominations of $100,000 and integral multiples of $1,000 in excess
thereof, and any attempted transfer, sale or other disposition of Subordinated


                                       8
<PAGE>   13
Notes in a denomination of less than $100,000 shall be deemed to be void and of
no legal effect whatsoever.

         SECTION 2.04. Exchange and Registration of Transfer of Securities;
Restrictions on Transfers; Depository. (a) If distributed to holders of
Preferred Securities in connection with a Dissolution Event, the Subordinated
Notes will be issued in the same form as the Preferred Securities that such
Subordinated Notes replace in accordance with the following procedures.

                  (i) If the Preferred Securities are held in global form, the
         Subordinated Notes shall be presented to the Trustee by the Property
         Trustee in exchange for a Global Debenture in an aggregate principal
         amount equal to the aggregate principal amount of all outstanding
         Subordinated Notes (a "GLOBAL SUBORDINATED NOTE"), to be registered in
         the name of the Depository, or its nominee, and delivered by the
         Property Trustee to the Depository for crediting to the accounts of its
         participants pursuant to the instructions of the Administrative
         Trustees. The Company upon any such presentation shall execute a Global
         Subordinated Note in such aggregate principal amount and deliver the
         same to the Trustee for authentication and delivery in accordance with
         the Indenture. Payments on the Subordinated Notes issued as a Global
         Subordinated Note will be made to the Depository.

                 (ii) If the Preferred Securities are held in certificated form,
         the Subordinated Notes shall be presented to the Trustee by the
         Property Trustee and each outstanding Preferred Security certificate
         will be deemed to represent a beneficial interest in such Subordinated
         Note in an aggregate principal amount equal to the aggregate
         Liquidation Amount of the Preferred Securities represented by such
         Preferred Security certificate. When the holder of a Preferred Security
         certificate presents such certificate for transfer or reissuance, such
         certificate will be canceled and a Subordinated Note, registered in the
         name of such holder or such holder's transferee, as the case may be, in
         an aggregate principal amount equal to the aggregate Liquidation Amount
         of the canceled certificate, will be executed by the Company and
         delivered to the Trustee for authentication and delivery in accordance
         with the Indenture. On issue of such Subordinated Notes, Subordinated
         Notes with an equivalent aggregate principal amount that were presented
         by the Property Trustee to the Trustee will be deemed to have been
         canceled.

          (b) Any Global Subordinated Note may be endorsed with or have
incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Indenture as may be required by the


                                       9
<PAGE>   14
Depository, by a national securities exchange or by the National Association of
Securities Dealers, Inc. in order for the Subordinated Notes to be tradeable on
the PORTAL Market or as may be required for the Subordinated Notes to be
tradeable on any other market developed for trading of securities pursuant to
Rule 144A or required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange upon
which the Subordinated Notes may be listed or traded or to conform with any
usage with respect thereto, or to indicate any special limitations or
restrictions to which any particular Subordinated Notes are subject.

          (c) Each Subordinated Note that bears or is required to bear the
legend set forth in this Section 2.04(c) (a "RESTRICTED SECURITY") shall be
subject to the restrictions on transfer provided in the legend set forth in this
Section 2.04(c), unless such restrictions on transfer shall be waived by the
written consent of the Company, and the Holder of each Restricted Security, by
such Holder's acceptance thereof, agrees to be bound by such restrictions on
transfer. As used in this Section 2.04(c) and in Section 2.04(d), the term
"transfer" encompasses any sale, pledge, transfer or other disposition of any
Restricted Security.

         Prior to the Transfer Restriction Termination Date, any certificate
evidencing a Subordinated Note shall bear a legend in substantially the
following form, unless otherwise agreed by the Company (with written notice
thereof to the Trustee):

         THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
         FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
         RULE 144A UNDER THE SECURITIES ACT), (2) AGREES THAT IT WILL NOT PRIOR
         TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE
         SECURITIES EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT
         (OR ANY SUCCESSOR PROVISION) RESELL OR OTHERWISE TRANSFER THE SECURITY
         EVIDENCED HEREBY EXCEPT (A) TO HERCULES INCORPORATED OR ANY SUBSIDIARY
         THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE
         144A UNDER THE SECURITIES ACT OR (C) TO A SECONDARY PURCHASER (AS
         DEFINED IN THE


                                       10
<PAGE>   15
         AMENDED AND RESTATED TRUST AGREEMENT OF HERCULES TRUST V DATED AS OF
         NOVEMBER 12, 1998 (AS AMENDED FROM TIME TO TIME, THE "TRUST
         AGREEMENT")) THAT HAS ENTERED INTO A SECONDARY PURCHASE AGREEMENT (AS
         DEFINED IN THE TRUST AGREEMENT) WITH THE TRUST, (3) AGREES THAT IT WILL
         DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS
         TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AT THE
         REQUEST OF THE HOLDER, THIS LEGEND WILL BE REMOVED AFTER THE EXPIRATION
         OF THE HOLDING PERIOD APPLICABLE TO THE SALE OF THE SECURITY EVIDENCED
         HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT AND (4) AGREES WITH
         RESPECT TO ANY TRANSFER OCCURRING PRIOR TO THE REMARKETING DATE ON
         WHICH REPLACEMENT NOTES ARE ISSUED TO ANY PERSON OTHER THAN THE
         PROPERTY TRUSTEE, TO PROVIDE TO THE INDENTURE TRUSTEE A DULY EXECUTED
         CERTIFICATE SUBSTANTIALLY TO THE EFFECT OF CLAUSES (1), (2) AND (3),
         ABOVE. THIS SECURITY WAS ISSUED WITH ORIGINAL ISSUE DISCOUNT FOR UNITED
         STATES FEDERAL INCOME TAX PURPOSE. THE ISSUE PRICE, AMOUNT OF ORIGINAL
         ISSUE DISCOUNT, ISSUE DATE, AND YIELD TO MATURITY WILL BE PROMPTLY MADE
         AVAILABLE UPON REQUEST TO THE VICE PRESIDENT - TAXES (AT (302)
         594-5887) OR THE SENIOR VICE PRESIDENT AND CHIEF FINANCIAL OFFICER (AT
         (302) 594-5175), HERCULES INCORPORATED, HERCULES PLAZA, 1313 NORTH
         MARKET STREET, WILMINGTON, DE 19894-0001.

         Following the Transfer Restriction Termination Date, any Subordinated
Note or security issued in exchange or substitution therefor (other than
Subordinated Notes acquired by the Company or any Affiliate), may upon surrender
of such Subordinated Note or security for exchange to the Trustee in accordance
with the provisions of this Section 2.04, be exchanged for a new Subordinated
Note or Subordinated Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.04(c).

          (d) Any Subordinated Note that, prior to the Transfer Restriction
Termination Date, is purchased or owned by the Company or any Affiliate thereof


                                       11
<PAGE>   16
may not be resold by the Company or such Affiliate unless registered under the
Securities Act or resold pursuant to an exemption from the registration
requirements thereof that results in such Subordinated Note no longer being a
"restricted security" as defined under Rule 144 under the Securities Act.

         SECTION 2.05. Interest. (a) Interest on the principal amount of each
Subordinated Note will accrue and be payable at a rate (the "INTEREST RATE") per
annum equal to

                  (i) from and including the date of issuance to but excluding
         the earlier of (A) the Remarketing Settlement Date on which Replacement
         Notes are issued and (B) the date such principal amount is paid, LIBOR
         plus 175 basis points, compounded quarterly;

                 (ii) from and including the Remarketing Settlement Date on
         which Replacement Notes are issued to but excluding the date such
         principal amount is paid, the Winning Bid Rate, compounded quarterly;
         and

                (iii) notwithstanding clauses (i) and (ii) above, if the Company
         fails to pay the principal amount on the date such amount becomes due,
         then from and including such due date to but excluding the date such
         principal amount is paid, the Default Rate, compounded quarterly, but
         only to the extent permitted by applicable law.

Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate specified above
(to the extent permitted by applicable law). The term "INTEREST", as used
herein, includes any such additional interest and Additional Interest unless
otherwise stated.

          (b) Until the Remarketing Settlement Date on which Replacement Notes
are issued, interest on the Subordinated Notes will be cumulative, will be
payable quarterly in arrears on February 12, May 12, August 12 and November 12
of each year, commencing February 12, 1999, and on such Remarketing Settlement
Date (each, a "PRE-REMARKETING INTEREST PAYMENT DATE"), will accumulate from and
including the most recent date to which interest has been paid or, if no
interest has been paid, from November 12, 1998, to but excluding the related
Pre-Remarketing Interest Payment Date, except as otherwise described below.

         The Interest Rate in effect for the period from and including November
12, 1998 to but excluding February 12, 1999 shall be the rate determined by the
Calculation Agent two London Banking Days prior to November 12, 1998 and


                                       12
<PAGE>   17
shall equal LIBOR plus 175 basis points. The Interest Rate in effect thereafter,
for each quarterly period from and including the immediately preceding
Pre-Remarketing Interest Payment Date to but excluding the applicable
Pre-Remarketing Interest Payment Date, shall be determined by the Calculation
Agent two London Banking Days prior to such immediately preceding
Pre-Remarketing Interest Payment Date and shall equal LIBOR plus 175 basis
points. The amount of interest payable for any quarterly period shall be
computed on the basis of a 360-day year of twelve 30-day months. Except as
provided in the last sentence of this paragraph, 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
30-day month. If a Pre-Remarketing Interest Payment Date is not a Business Day,
then such Pre-Remarketing Interest Payment Date will be the next succeeding
Business Day, except if such Business Day is in the next succeeding calendar
month, such Pre-Remarketing Interest Payment Date will be the immediately
preceding Business Day.

          (c) Interest shall be paid to the Person in whose name such
Subordinated Note or any predecessor Subordinated Note is registered on the
books and records of the Company at the close of business on the Regular Record
Date for such interest installment, which shall be fifteen (15) days prior to a
Pre-Remarketing Interest Payment Date (the "PRE-REMARKETING REGULAR RECORD
DATE").

          (d) From and including the Remarketing Settlement Date on which
Replacement Notes are issued, interest on the Replacement Notes will be
cumulative, will be payable quarterly in arrears on February 12, May 12, August
12 and November 12 of each year, commencing on the Remarketing Settlement Date,
and on the Maturity Date (each, an "INTEREST PAYMENT DATE"), will accumulate
from the most recent date to which interest has been paid or, if no interest has
been paid, from and including the Remarketing Settlement Date, to but excluding
the related Interest Payment Date, except as otherwise described below. The
amount of interest payable for any quarterly period shall be computed on the
basis of a 360-day year of twelve 30-day months. Except as provided in the last
sentence of this paragraph, 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 30-day month. If
an Interest Payment Date is not a Business Day, then such Interest Payment Date
will be the next succeeding Business Day, except if such Business Day is in the
next succeeding calendar month, such Interest Payment Date will be the
immediately preceding Business Day.

          (e) Interest shall be paid to the Person in whose name the
Subordinated Note or any predecessor Subordinated Note is registered on the
books and records of the Company, at the close of business on the Regular Record
Date for such 


                                       13
<PAGE>   18
interest installment, which, in respect of (i) Subordinated Notes of which the
Property Trustee is the Holder and the related Preferred Securities are in
book-entry only form or (ii) a Global Subordinated Note, shall be the close of
business on the Business Day next preceding that Interest Payment Date (the
"REGULAR RECORD DATE"). If the Subordinated Notes are not represented by a
Global Subordinated Note, the Regular Record Date for such interest installment
shall be fifteen (15) days prior to that Interest Payment Date.

          (f) If, at any time while the Property Trustee is the Holder of any
Subordinated Notes, the Trust or the Property 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 Subordinated Notes held by the Property Trustee,
such additional amounts as shall be required so that the net amounts received
and retained by the Trust and the Property Trustee after paying such taxes,
duties, assessments or other governmental charges will be equal to the amounts
the Trust and the Property Trustee would have received had no such taxes,
duties, assessments or other government charges been imposed.

Indenture) at any time, upon not less than 30 nor more than 60 days notice, to
redeem the Subordinated Notes in whole, but not in part, within the 90 days
following the occurrence of such Special Event (the "90 DAY PERIOD"), and,

Pro Rata basis at a redemption price equal to 100% of the principal amount of
the Subordinated Notes plus any accrued and unpaid interest thereon to the date
of such redemption (the "REDEMPTION PRICE"), provided that if at the time there
is available to the Company or the Trust the opportunity to eliminate, within
the 90-Day Period, the Special 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 has no adverse effect on the
Company, the Trust or the Holders of the Trust Securities issued by the Trust,
the Company shall pursue such Ministerial Action in lieu of redemption, and,
provided, further, that the Company shall have no right to redeem the
Subordinated Notes while the Trust is pursuing 


                                       14
<PAGE>   19
any Ministerial Action pursuant to its obligations under the Trust Agreement.
The Redemption Price shall be paid prior to 12:00 noon, New York City time, on
the date of such redemption or such earlier time as the Company determines,
provided that the Company shall deposit with the Trustee an amount sufficient to
pay the Redemption Price prior to the Redemption Date.

         SECTION 3.02. Optional Redemption by Company. The Subordinated Notes
are not entitled to any optional redemption by the Company.

         SECTION 3.03. No Sinking Fund. The Subordinated Notes are not entitled
to the benefit of any sinking fund.

         SECTION 3.04. Mandatory Redemption upon a Failed Remarketing. If a

whole at the Redemption Price on the third Business Day following the date such
Failed Remarketing occurs or is deemed to occur in the manner set forth in
Article 3 of the Base Indenture as though a notice of redemption had been timely
given as required by Sections 3.01 and 3.03 of the Base Indenture. The
Redemption Price shall be paid prior to 12:00 noon, New York City time, on the
date of such redemption or such earlier time as the Company determines, provided
that the Company shall deposit with the Trustee an amount sufficient to pay the
Redemption Price prior to the Redemption Date



                                    ARTICLE 4

         SECTION 4.01. Extension of Interest Payment Period. The Company is not
entitled at any time during the term of the Subordinated Notes to the benefit of
any interest payment deferral or extension.

                  (b) pay all costs and expenses of the Trust (other than

prohibit the making of any payment of monies to or by the Trustee in respect of
the Subordinated Notes pursuant to the provisions of this Article.
Notwithstanding any of the provisions of the Base Indenture or this First
Supplemental Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies

have full power and authority to receive such money and to apply the same to the
purposes for which it was received, and shall not be affected by any notice to
the contrary that may be received by it on or after the second Business Day
prior to such date.

         SECTION 6.02. Power of Attorney. Each Holder by acceptance of the
Subordinated Notes hereby irrevocably constitutes and appoints the Remarketing
Agent and each of its officers as such Holder's true and lawful representative
and attorney-in-fact, with full power and authority in such person's name, place
and stead to make, execute, acknowledge, deliver, swear to, record and file with

Remarketing Agreement. (a) Sections 10.02, 10.04 and 10.06 shall become

         be unable to meet the conditions to Remarketing in the absence of such
         a delay; and

                  (ii) the Remarketing Agent may, by notice to the Company,
         direct that the Reset Date be delayed if the Remarketing Agent believes
         that a Remarketing will not be successful in the absence of such a
         delay;

and, in either such event, the Company and the Remarketing Agent will use their
best efforts to establish a delayed Reset Date that is within five Business Days
after the Expected Reset Date, but in no event later than the Final Reset Date;
and provided further, that no Reset Date may be established if any Default (as
defined in the Credit Agreement) has occurred, except in connection with a
Remarketing following a Cured Default Trigger Event pursuant to Section 10.06.
If the Company and the Remarketing Agent have not agreed, on or prior to the
sixth Business Day preceding the Final Reset Date, to a Reset Date that is not
later than the Final Reset Date, no Remarketing shall occur and the Company
shall repay the Subordinated Notes in accordance with their terms.

           (b) The Company shall, by notice to the Remarketing Agent no later
than five Business Days prior to the Reset Date, select and specify three
Reference Corporate Dealers. By 3:00 p.m., New York City time, on the Reset
Date, the Remarketing Agent shall request Bids from such Reference Corporate
Dealers. The Remarketing Agent shall determine the lowest Bid Rate (the "WINNING
BID RATE") from among the Bids obtained on the Reset Date. By approximately 4:30
p.m., New York City time, on the Reset Date, the Remarketing Agent shall notify
the Company, the Underwriter and the Trustee of the Winning Bid Rate. If on a
Reset Date, Bids are not submitted by at least two 


                                       19
<PAGE>   24
Reference Corporate Dealers, or if the lowest Bid submitted would result in a
Winning Bid Rate in excess of the rate permitted by applicable law, such
Remarketing shall be deemed to be a Failed Remarketing on the corresponding
Remarketing Settlement Date. The Winning Bid Rate determined by the Remarketing
Agent, absent manifest error, shall be binding and conclusive upon the Holders
of the Subordinated Notes and the Company.

           (c) On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "SECONDARY PURCHASER") the Reference Corporate Dealer
providing the Bid containing the Winning Bid Rate. If the Winning Bid Rate is
specified in the Bids submitted by two or more Reference Corporate Dealers, the
Remarketing Agent shall, in its sole discretion, designate one of such Reference
Corporate Dealers as the Secondary Purchaser.

           (d) On the Reset Date, the Secondary Purchaser shall enter into a
Secondary Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate principal amount of Subordinated Notes, with
an Interest Rate equal to the Winning Bid Rate and with a Maturity Date on the
Maturity Extension Date.

           (e) If a Remarketing has occurred pursuant to this Section 10.02 but
settlement of the purchase and sale of the Subordinated Notes does not occur on
the corresponding Remarketing Settlement Date, then, unless the provisions of
Section 10.04 with respect to a Renewed Remarketing shall apply, a Failed
Remarketing shall be deemed to occur on such Remarketing Settlement Date.

           (f) At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay to the Remarketing Agent on behalf
of the Holders of the Subordinated Notes on the Remarketing Settlement Date, an
amount of cash equal to the Remarketing Price.

           (g) Unless otherwise agreed among the Remarketing Agent, the Paying
Agent and any Former Holder, the Remarketing Agent shall pay the Remarketing
Price, less the Remarketing Fee, to the Paying Agent, acting solely as agent for
the Former Holders, and the Paying Agent shall promptly pay such amounts to the
Former Holders in the same manner as is specified in Section 2.02 of the Base
Indenture for payments of interest, except that the Record Date therefor shall
be the Business Day immediately preceding the Remarketing Settlement Date.

           (h) The obligation of the Remarketing Agent to make payment to the
Former Holders in connection with the Remarketing shall be limited to the extent
that the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

<PAGE>   25
           (i) Any outstanding Subordinated Notes purchased on the Remarketing
Settlement Date shall be deemed to be transferred to the Secondary Purchaser and
shall be replaced in the manner provided in Section 10.02(j). On and after the
Remarketing Settlement Date (except in the event of a Failed Remarketing), the
Company shall make no further payments to, and the Company shall have no further
obligations under this First Supplemental Indenture in respect of, the Holders
of such replaced Subordinated Notes (the "FORMER HOLDERS"), the Company shall
only be obligated to make payments to the Holders of Replacement Notes, and the
Subordinated Notes of the Former Holders shall no longer represent an obligation
of the Company but shall only represent a right to receive the proceeds of the
Remarketing from the Paying Agent.

           (j) The Company shall cause replacement certificates evidencing the
remarketed Subordinated Notes to be executed by the Company and authenticated by
the Trustee in accordance with the provisions of Section 2.03 of the Base
Indenture (the "REPLACEMENT NOTES"). The Replacement Notes shall be delivered to
the purchaser or purchasers of the remarketed Subordinated Notes in accordance
with the terms of the Secondary Purchase Agreement.

         SECTION 10.03. Reset of Interest Rate and Maturity Date. Unless a
Failed Remarketing shall have occurred, from and including the Reset Settlement
Date, the Interest Rate on the Subordinated Notes shall be the Winning Bid Rate
and the Maturity Date shall be the Maturity Extension Date.

         SECTION 10.04. Renewed Remarketing. If a Remarketing has occurred
pursuant to Section 10.02 that would be a Failed Remarketing solely pursuant to
Section 10.02(e), but the purchase and sale of the Subordinated Notes does not
take place on the corresponding Remarketing Settlement Date, and the reason for
such failure shall, in the good faith determination of the Remarketing Agent
(made after consultation with the Company), result from facts or circumstances
that are not due to the action or inaction of the Company, then the provisions
of Sections 10.02 and 10.06 shall apply to a second remarketing (a "RENEWED
REMARKETING") of the Subordinated Notes, except that the Expected Reset Date
shall be the sixth Business Day following such corresponding Remarketing
Settlement Date; provided that the provisions of this Section 10.04 shall be
applied only once.

         SECTION 10.05. Failed Remarketing; Mandatory Redemption. The
Remarketing Agent shall give notice of any Failed Remarketing on the date such
Failed Remarketing occurs or is deemed to have occurred, by 4:00 p.m., New York
City time, on the date of such Failed Remarketing, to the Company, the Trustee,
the Underwriter and the Paying Agent. In the case of any Failed


                                       21
<PAGE>   26
Remarketing, the Company shall redeem the Subordinated Notes in whole, but not
in part, within three Business Days following the date such Failed Remarketing
occurs or is deemed to occur as provided in Section 3.04.

         SECTION 10.06. Early Remarketing. If any of the following events (each,
a "TRIGGER EVENT") shall have occurred:

           (a) the Closing Price of the Common Stock on any Trading Day, as
determined by the Remarketing Agent, is less than the Trigger Price (a "STOCK
PRICE TRIGGER EVENT");

           (b) a Cross Default shall have occurred but such Cross Default shall
have ceased to be continuing (a "CURED DEFAULT TRIGGER EVENT"); or

           (c) the Company (i) shall have made a written request to the
Underwriter to enter into a firm commitment underwriting of the Common Stock,
and the Company and the Underwriter shall have substantially agreed to the terms
of such underwriting in the manner described in Section 12 of the Forward
Underwriting Agreement or (ii) shall have given notice to accelerate the
Commencement Date in the manner described in Section 7 of the Forward
Underwriting Agreement (an "UNDERWRITING TRIGGER EVENT");

then a Remarketing shall occur pursuant to Sections 10.02 and, if applicable,
Section 10.04, except that:

           (A) the Expected Reset Date shall be the sixth Business Day following
the date such Trigger Event first occurs;

           (B) in the case of a Stock Price Trigger Event or a Cured Default
Trigger Event, the Final Reset Date shall be the 15th day following the date
such Trigger Event occurs, or the 20th day in the case of a Renewed Remarketing
to which the provisions of Section 10.04 apply, but in no event later than the
third scheduled Trading Day prior to November 10, 1999;

           (C) in the case of an Underwriting Trigger Event, the Final Reset
Date shall be the 45th day following the date such Trigger Event occurs, but in
no event later than the third scheduled Trading Day prior to November 10, 1999;
and

           (D) notwithstanding the provisions of clauses (A), (B) and (C) above,
if a Reset Date has already been established or a Remarketing has already taken
place at the time such Trigger Event occurs, the Remarketing shall occur on such
established Reset Date or settled on the corresponding Remarketing Settlement
Date.

facto become and be immediately due and payable without any declaration or other

              AUCTION RATE RESET JUNIOR SUBORDINATED NOTE SERIES A

                  Hercules Incorporated, a Delaware corporation (the "COMPANY",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay the principal sum of
_________ Dollars ($     ) on November 10, 1999, or such other date as may be
provided pursuant to the terms of the Indenture.

           (a) Interest on the principal amount of this Subordinated Note will
accrue and be payable at a rate (the "INTEREST RATE") per annum equal to

                   (i) from and including the date of issuance to but excluding
         the date on which the principal amount of this Subordinated Note
         becomes due upon the maturity, acceleration or redemption thereof,
         LIBOR plus 175 basis points, compounded quarterly;

                  (ii) except as provided in clause (iii) below, from and
         including the Remarketing Settlement Date on which Replacement Notes
         are issued to but excluding the date on which the principal amount of
         the Subordinated Notes becomes due upon the maturity, acceleration or
         redemption thereof, the Winning Bid Rate, compounded quarterly; and

                 (iii) if the Company fails to pay the principal amount due upon
         the maturity, acceleration or redemption of this Subordinated Notes on
         the date such amount becomes due (other than as a result of an
         acceleration pursuant to Section 6.01(e) or (f) of the Base Indenture),
         from and including such due date to but excluding the date of actual
         payment by the Company, the Default Rate, compounded quarterly.

Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate (to the extent
permitted by applicable law). The term "INTEREST", as used herein, includes any
such additional interest and Additional Interest unless otherwise stated.


                                      A1-3
<PAGE>   33
           (b) Until the Remarketing Settlement Date on which Replacement Notes
are issued, interest on this Subordinated Note will be cumulative, will be
payable quarterly in arrears on February 12, May 12, August 12 and November 12
of each year, commencing February 12, 1999, and on such Remarketing Settlement
Date (each, a "PRE-REMARKETING INTEREST PAYMENT DATE"), will accumulate from and
including the most recent date to which interest has been paid or, if no
interest has been paid, from November 12, 1998, to but excluding the related
Pre-Remarketing Interest Payment Date, except as otherwise described below.

         The Interest Rate in effect for the period from and including November
12, 1998 to but excluding February 12, 1999 shall be the rate determined by the
Calculation Agent two London Banking Days prior to November 12, 1998 and shall
equal LIBOR plus 175 basis points. The Interest Rate in effect thereafter, for
each quarterly period from and including the immediately preceding
Pre-Remarketing Interest Payment Date to but excluding the applicable
Pre-Remarketing Interest Payment Date, shall be determined by the Calculation
Agent two London Banking Days prior to such immediately preceding
Pre-Remarketing Interest Payment Date and shall equal LIBOR plus 175 basis
points. The amount of interest payable for any quarterly period shall be
computed on the basis of a 360-day year of twelve 30-day months. Except as
provided in the last sentence of this paragraph, 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
30-day month. If a Pre-Remarketing Interest Payment Date is not a Business Day,
then such Pre-Remarketing Interest Payment Date will be the next succeeding
Business Day, except if such Business Day is in the next succeeding calendar
month, such Pre-Remarketing Interest Payment Date will be the immediately
preceding Business Day.

         As used herein, "LONDON BANKING DAY" means any day on which dealings in
deposits in U.S. Dollars are transacted in the London interbank market.

           (c) From and including the Remarketing Settlement Date on which
Replacement Notes are issued, interest on the Replacement Notes will be
cumulative, will be payable quarterly in arrears on February 12, May 12, August
12 and November 12 of each year, commencing on the Remarketing Settlement Date,
and on the Maturity Date (each, an "INTEREST PAYMENT DATE"), will accumulate
from the most recent date to which interest has been paid or, if no interest has
been paid, from and including the Remarketing Settlement Date, to but excluding
the related Interest Payment Date, except as otherwise described below. The
amount of interest payable for any quarterly period shall be computed on the
basis of a 360-day year of twelve 30-day months. Except as provided in the last
sentence of this paragraph, the amount of interest payable for any period


                                      A1-4
<PAGE>   34
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 30-day month. If
an Interest Payment Date is not a Business Day, then such Interest Payment Date
will be the next succeeding Business Day, except if such Business Day is in the
next succeeding calendar month, such Interest Payment Date will be the
immediately preceding Business Day.

           (d) Interest shall be paid to the Person in whose name this
Subordinated Note or any predecessor Subordinated Note is registered on the
books and records of the Company at the close of business on the Regular Record
Date for such interest installment, which shall be fifteen (15) days prior to a
Pre-Remarketing Interest Payment Date (the "PRE-REMARKETING REGULAR RECORD
DATE"). Notwithstanding the foregoing, so long as the Holder of this
Subordinated Note is the Property Trustee, the payment of the principal of (and
premium, if any) and interest on this Subordinated Note will be made at such
place and to such account as may be designated by the Property Trustee.

         The indebtedness evidenced by this Subordinated Note is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness, and this
Subordinated Note is issued subject to the provisions of the Indenture with
respect thereto. Each Holder of this Subordinated Note, by accepting the same,
(a) agrees to and shall be bound by such provisions, (b) authorizes and directs
the Trustee on his or her behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination so provided and (c)
appoints the Trustee his or her attorney-in-fact for any and all such purposes.
Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         This Subordinated Note shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any purpose
until the Certificate of Authentication hereon shall have been signed by or on
behalf of the Trustee.

         The provisions of this Subordinated Note are continued on the reverse
side hereof and such continued provisions shall for all purposes have the same
effect as though fully set forth at this place.

the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the Holders of the Subordinated Notes. By the
terms of the Indenture, the Debentures are issuable thereunder in series that
may vary as to amount, date of maturity, rate of interest and in other respects
as provided in the Indenture. This series of Debentures is limited in aggregate
principal amount as specified in said First Supplemental Indenture and herein
sometimes referred to as the "SUBORDINATED NOTES."

         Because of the occurrence and continuation of a Special Event or a
Failed Remarketing, in certain circumstances, this Subordinated Note may become
due and payable at the principal amount together with any interest accrued
thereon (the "REDEMPTION PRICE"). The Redemption Price shall be paid prior to
12:00 noon, New York City time, on the date of such redemption or at such
earlier time as the Company determines.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Subordinated Notes may
be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of at least a majority in aggregate
principal amount of the Debentures of each series affected thereby then
outstanding (and, in the case of any series of Debentures held as assets of a
Trust and with respect to which a Dissolution Event has not theretofore
occurred, such consent of holders of the Preferred Securities and the Common
Securities of such Trust as may be required under the Trust Agreement), as
defined in the Indenture, to reduce the principal amount of such Debentures;
reduce the percentage of the principal amount of such Debentures the Holders of
which must consent to an amendment of this Indenture or a waiver; change (i) the
stated maturity of the principal of or the interest on such Debentures, or (ii)
the rate of interest (or the manner of calculation thereof) on such Debentures,
change adversely to the 


                                      A1-8

Holders the redemption, conversion or exchange provisions applicable to such
Debentures, if any; change the currency in respect of which the payments on such
Debentures are to be made; make any change in the Subordination provisions of
the Indenture (Article 10) that adversely affects the rights of the Holders of
the Debentures or any change to any other Section hereof that adversely affects
their rights; or change the direct action rights of holders of Preferred
Securities; provided that, in the case of the outstanding Debentures of a series
then held by a Trust, no such amendment shall be made that adversely affects the
holders of the Preferred Securities of that Trust, and no waiver of any Event of
Default with respect to the Debentures of that series or compliance with any
covenant under this Indenture shall be effective, without the prior consent of
the holders of at least a majority of the aggregate liquidation amount of the
outstanding Preferred Securities of that Trust or the holder of each such
Preferred Security, as applicable.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Debentures, or which modifies
the rights of the Holders of Debentures of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Debentures of any other series.

         No reference herein to the Indenture and no provision of this
Subordinated Note or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Subordinated Note at the time and place
and at the rate or rates and in the currency herein prescribed.

         As provided in the Indenture and subject to certain limitations herein
and therein set forth, this Subordinated Note is transferable by the registered
Holder hereof on the Register of the Company, upon surrender of this
Subordinated Note for registration of transfer at the office or agency of the
Trustee in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Subordinated Notes of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

         Prior to due presentment for registration of transfer of this
Subordinated Note, the Company, the Trustee, any paying agent and the Registrar
may deem 


                                      A1-9
<PAGE>   39
and treat the registered holder hereof as the absolute owner hereof (whether or
not this Subordinated Note shall be overdue and notwithstanding any notice of
ownership or writing hereon made by anyone other than the Registrar) for the
purpose of receiving payment of or on account of the principal hereof and
premium, if any, and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any Registrar shall be
affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Subordinated Note, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         The Subordinated Notes of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple of
$1,000 thereof. The Subordinated Notes may be transferred or exchanged only in
minimum denominations of $100,000 and integral multiples of $1,000 in excess
thereof, and any attempted transfer, sale or other disposition of Subordinated
Notes in a denomination of less than $100,000 shall be deemed void and of no
legal effect whatsoever.

         All terms used in this Subordinated Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE DEBENTURES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS
PRINCIPLES OF CONFLICTS OF LAWS.

a Book-Entry Note within the meaning of the Indenture hereinafter referred to
and is registered in the name of a Depository or a nominee of a Depository. This

authorized representative of The Depository Trust Company and any payment hereon
is made to Cede & Co., ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY A PERSON IS WRONGFUL since the registered owner hereof, Cede & Co.,
has an interest herein.

         Hercules Incorporated, a Delaware corporation (the "COMPANY", which
term includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay the principal sum of _________
Dollars ($      ) on the Maturity Date or such earlier date as may be provided
pursuant to the terms of the Indenture.

         Interest on the principal amount of this Subordinated Note will accrue
and be payable at a rate (the "INTEREST RATE") per annum equal to (i) from and
including the date of issuance to but excluding the date such principal amount
is paid, the Winning Bid Rate, compounded quarterly; and (ii) notwithstanding
clause (i) above, if the Company fails to pay the principal amount on the date
such amount becomes due, then from and including such due date to but excluding
the date such principal amount is paid, the Default Rate, compounded quarterly,
but only to the extent permitted by applicable law.

Interest that is not paid when due will bear additional interest thereon
compounded quarterly at the applicable periodic Interest Rate specified above
(to the extent permitted by applicable law). The term "INTEREST", as used
herein, includes any such additional interest and Additional Interest unless
otherwise stated.

         From and including the date of issuance, interest on this Replacement
Note will be cumulative, will be payable quarterly in arrears on February 12,
May 12, August 12 and November 12 of each year, commencing on the Remarketing
Settlement Date, and on the Maturity Date (each, an "INTEREST PAYMENT DATE"),
will accumulate from the most recent date to which interest has been paid or, if
no interest has been paid, from and including the date of issuance, to but
excluding the related Interest Payment Date, except as otherwise described
below. The amount of interest payable for any quarterly period shall be computed
on the basis of a 360-day year of twelve 30-day months. Except as provided in
the last sentence of this paragraph, 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 30-day month.
If an Interest Payment Date is not a Business Day, then such Interest Payment
Date will be the next succeeding Business Day, except if such Business Day is in
the next 


                                      A2-3

succeeding calendar month, such Interest Payment Date will be the immediately
preceding Business Day.

         Interest shall be paid to the Person in whose name the Subordinated
Note or any predecessor Subordinated Note is registered on the books and records
of the Company at the close of business on the Regular Record Date for such
interest installment, which, in respect of (iii) Subordinated Notes of which the
Property Trustee is the Holder and the related Preferred Securities are in
book-entry only form or (iv) a Global Subordinated Note, shall be the close of
business on the Business Day next preceding that Interest Payment Date (the
"REGULAR RECORD DATE"). If the Subordinated Notes are not represented by a
Global Subordinated Note, the Regular Record Date for such interest installment
shall be fifteen (15) days prior to an Interest Payment Date. Notwithstanding
the foregoing, so long as the Holder of this Subordinated Note is the Property
Trustee, the payment of the principal of (and premium, if any) and interest on
this Subordinated Note will be made at such place and to such account as may be
designated by the Property Trustee.

         The indebtedness evidenced by this Subordinated Note is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness, and this
Subordinated Note is issued subject to the provisions of the Indenture with
respect thereto. Each Holder of this Subordinated Note, by accepting the same,
(a) agrees to and shall be bound by such provisions, (b) authorizes and directs
the Trustee on his or her behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination so provided and (c)
appoints the Trustee his or her attorney-in-fact for any and all such purposes.
Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         This Subordinated Note shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any purpose
until the Certificate of Authentication hereon shall have been signed by or on
behalf of the Trustee.

         The provisions of this Subordinated Note are continued on the reverse
side hereof and such continued provisions shall for all purposes have the same
effect as though fully set forth at this place.

                            [FORM OF REVERSE OF NOTE]

         This Subordinated Note is one of a duly authorized series of Debentures
of the Company (herein sometimes referred to as the "DEBENTURES"), specified in
the Indenture, all issued or to be issued in one or more series under and
pursuant to a Junior Subordinated Debenture Indenture dated as of November 12,
1998, duly executed and delivered between the Company and The Chase Manhattan
Bank, as Trustee (the "TRUSTEE"), as supplemented by the First Supplemental
Indenture dated as of November 12, 1998, between the Company and the Trustee
(the Indenture as so supplemented, the "INDENTURE"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the Holders of the Subordinated Notes. By the
terms of the Indenture, the Debentures are issuable thereunder in series that
may vary as to amount, date of maturity, rate of interest and in other respects
as provided in the Indenture. This series of Debentures is limited in aggregate
principal amount as specified in said First Supplemental Indenture and herein
sometimes referred to as the "SUBORDINATED NOTES."

         Because of the occurrence and continuation of a Special Event, in
certain circumstances, this Subordinated Note may become due and payable at the
principal amount together with any interest accrued thereon (the "REDEMPTION
PRICE"). The Redemption Price shall be paid prior to 12:00 noon, New York City
time, on the date of such redemption or at such earlier time as the Company
determines.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Subordinated Notes may
be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of at least a majority in aggregate
principal amount of the Debentures of each series affected thereby then
outstanding (and, in the case of any series of Debentures held as assets of a
Trust and with respect to which a Dissolution Event has not theretofore
occurred, such consent of holders of the Preferred Securities and the Common
Securities of such Trust as may be required under the Trust Agreement), as
defined in the Indenture, to reduce the principal amount of such Debentures;
reduce the percentage of the principal amount of such Debentures the Holders of
which must consent to an amendment of this Indenture or a waiver; change (i) the
stated maturity of the principal of or the interest on such Debentures, or (ii)
the rate of interest (or the manner of calculation thereof) on such Debentures,
change adversely to the 


                                      A2-7
<PAGE>   47
Holders the redemption, conversion or exchange provisions applicable to such
Debentures, if any; change the currency in respect of which the payments on such
Debentures are to be made; make any change in the Subordination provisions of
the Indenture (Article 10) that adversely affects the rights of the Holders of
the Debentures or any change to any other Section hereof that adversely affects
their rights; or change the direct action rights of holders of Preferred
Securities; provided that, in the case of the outstanding Debentures of a series
then held by a Trust, no such amendment shall be made that adversely affects the
holders of the Preferred Securities of that Trust, and no waiver of any Event of
Default with respect to the Debentures of that series or compliance with any
covenant under this Indenture shall be effective, without the prior consent of
the holders of at least a majority of the aggregate liquidation amount of the
outstanding Preferred Securities of that Trust or the holder of each such
Preferred Security, as applicable.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Debentures, or which modifies
the rights of the Holders of Debentures of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Debentures of any other series.

         No reference herein to the Indenture and no provision of this
Subordinated Note or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Subordinated Note at the time and place
and at the rate or rates and in the currency herein prescribed.

         As provided in the Indenture and subject to certain limitations herein
and therein set forth, this Subordinated Note is transferable by the registered
Holder hereof on the Register of the Company, upon surrender of this
Subordinated Note for registration of transfer at the office or agency of the
Trustee in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Trustee duly
executed by the registered Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Subordinated Notes of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

         Prior to due presentment for registration of transfer of this
Subordinated Note, the Company, the Trustee, any paying agent and the Registrar
may deem 


                                      A2-8
<PAGE>   48
and treat the registered holder hereof as the absolute owner hereof (whether or
not this Subordinated Note shall be overdue and notwithstanding any notice of
ownership or writing hereon made by anyone other than the Registrar) for the
purpose of receiving payment of or on account of the principal hereof and
premium, if any, and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any Registrar shall be
affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Subordinated Note, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         The Subordinated Notes of this series are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple of
$1,000 thereof. The Subordinated Notes may be transferred or exchanged only in
minimum denominations of $100,000 and integral multiples of $1,000 in excess
thereof, and any attempted transfer, sale or other disposition of Subordinated
Notes in a denomination of less than $100,000 shall be deemed void and of no
legal effect whatsoever. This Global Subordinated Note is exchangeable for
Subordinated Notes in definitive form only under certain limited circumstances
set forth in the Indenture.

         All terms used in this Subordinated Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE DEBENTURES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS
PRINCIPLES OF CONFLICTS OF LAWS.

herein) from time to time of the Preferred Securities (as defined herein) of
Hercules Trust V, a statutory business trust formed under the laws of the State
of Delaware (the "ISSUER").

         WHEREAS, pursuant to an Amended and Restated Trust Agreement (the

and to make certain other payments on the terms and conditions set forth herein.

         WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "COMMON SECURITIES GUARANTEE") with substantially identical terms
to this Preferred Securities Guarantee, for the benefit of the holders of the

Guarantee are subordinated, to the extent and in the manner set forth in the

receive Guarantee Payments under this Preferred Securities Guarantee.

         NOW, THEREFORE, in consideration of the purchase by each Holder of
Preferred Securities, which purchase the Guarantor hereby acknowledges shall
benefit the Guarantor, the Guarantor executes and delivers this Preferred

Securities, and the Preferred Securities Guarantee Trustee shall not transfer
this Preferred Securities Guarantee to any Person except a Holder of Preferred

Successor Preferred Securities Guarantee Trustee, and such vesting and
succession of title shall be effective whether or not conveyancing documents
have been executed and delivered pursuant to the appointment of such Successor
Preferred Securities Guarantee Trustee.

          (b) If an Event of Default actually known to a Responsible Officer of

of any Event of Default and after the curing of all Events of Default that may

set forth in this Preferred Securities Guarantee, and no implied covenants shall
be read into this Preferred Securities Guarantee against the Preferred
Securities Guarantee Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.06) and is actually known to a
Responsible Officer of the Preferred Securities Guarantee Trustee, the Preferred
Securities Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities Guarantee, and use the same degree of care
and skill in its exercise thereof, as a prudent person would exercise or use
under the circumstances in the conduct of his or her own affairs.

          (d) No provision of this Preferred Securities Guarantee shall be
construed to relieve the Preferred Securities Guarantee Trustee from liability
for its own negligent action, its own negligent failure to act, its own bad
faith or its own willful misconduct, except that:

              (i) prior to the occurrence of any Event of Default and after the
         curing or waiving of all such Events of Default that may have occurred:

                       (A) the duties and obligations of the Preferred
                  Securities Guarantee Trustee shall be determined solely by the
                  express provisions of this Preferred Securities Guarantee, and
                  the Preferred Securities Guarantee Trustee shall not be liable
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Preferred Securities
                  Guarantee, and no implied covenants or obligations shall be
                  read into this Preferred Securities Guarantee against the
                  Preferred Securities Guarantee Trustee; and


                                        9
<PAGE>   13
                       (B) in the absence of bad faith on the part of the
                  Preferred Securities Guarantee Trustee, the Preferred
                  Securities Guarantee 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 Preferred Securities Guarantee Trustee and conforming
                  to the requirements of this Preferred Securities Guarantee;
                  provided, however, that in the case of any such certificates
                  or opinions that by any provision hereof are specifically
                  required to be furnished to the Preferred Securities Guarantee
                  Trustee, the Preferred Securities Guarantee Trustee shall be
                  under a duty to examine the same to determine whether or not
                  they conform to the requirements of this Preferred Securities
                  Guarantee (but shall not be required to confirm or investigate
                  the accuracy of mathematical calculations or other facts
                  stated therein);

                  (ii) the Preferred Securities Guarantee Trustee shall not be
         liable for any error of judgment made in good faith by a Responsible
         Officer of the Preferred Securities Guarantee Trustee, unless it shall
         be proved that the Preferred Securities Guarantee Trustee was negligent
         in ascertaining the pertinent facts upon which such judgment was made;

                  (iii) the Preferred Securities Guarantee 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 a
         Majority in Liquidation Amount of the Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Preferred Securities Guarantee Trustee, or exercising
         any trust or power conferred upon the Preferred Securities Guarantee

         require the Preferred Securities Guarantee 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 the Preferred Securities Guarantee Trustee 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
         Preferred Securities Guarantee or indemnity reasonably satisfactory to
         the Preferred Securities Guarantee Trustee against such risk or

         Officers' Certificate.

                  (iii) Whenever, in the administration of this Preferred
         Securities Guarantee, the Preferred Securities Guarantee Trustee shall
         deem it desirable that a matter be proved or established before taking,
         suffering or omitting any action hereunder, the Preferred Securities
         Guarantee Trustee (unless other evidence is herein specifically
         prescribed) may, in the absence of bad faith on its part, request and
         conclusively rely upon an Officers' Certificate which, upon receipt of
         such request, shall be promptly delivered by the Guarantor.

                  (iv) The Preferred Securities Guarantee Trustee shall have no
         duty to see to any recording, filing or registration of any instrument

         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

         no obligation to exercise any of the rights or powers vested in it by
         this Preferred Securities Guarantee at the request or direction of any

         upon the occurrence of an Event of Default, of its obligation to
         exercise the rights and powers vested in it by the terms of this
         Preferred Securities Guarantee.

                  (vii) The Preferred Securities Guarantee Trustee shall not be
         bound to make any investigation into the facts or matters stated in any

         any of the trusts or powers hereunder or perform any duties hereunder
         either directly or by or through agents, nominees, custodians or
         attorneys, and the Preferred Securities Guarantee 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 Preferred Securities Guarantee
         Trustee or its agents hereunder shall bind the Holders of the Preferred
         Securities, and the signature of the Preferred Securities Guarantee
         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 Preferred Securities Guarantee Trustee to so
         act or as to its compliance with any of the terms and provisions of
         this Preferred Securities Guarantee, both of which shall be
         conclusively evidenced by the Preferred Securities Guarantee Trustee's
         or its agent's taking such action.

                  (x) Whenever in the administration of this Preferred
         Securities Guarantee the Preferred Securities Guarantee Trustee shall
         deem it desirable to receive instructions with respect to enforcing any
         remedy or right or taking any other action hereunder, the Preferred

         refrain from enforcing such remedy or right or taking such other action
         until such instructions are received, and (C) shall be protected in
         conclusively relying on or acting in accordance with such instructions.

                  (xi) Except as otherwise expressly provided by this Preferred
         Securities Guarantee, the Preferred Securities Guarantee Trustee shall

         under the provisions of this Preferred Securities Guarantee Agreement.

                  (xii) The Preferred Securities Guarantee Trustee shall not be
         liable for any action taken, suffered, or omitted to be taken by it in

         authorized or within the discretion or rights or powers conferred upon
         it by this Preferred Securities Guarantee.

          (b) No provision of this Preferred Securities Guarantee shall be
deemed to impose any duty or obligation on the Preferred Securities Guarantee
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 Preferred Securities Guarantee 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 Preferred Securities Guarantee
Trustee shall be construed to be a duty.

         SECTION 5.01. Guarantee. The Guarantor irrevocably and unconditionally
agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim that the Issuer may have or assert.
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 Issuer to pay such amounts to the Holders.

         SECTION 5.02. Waiver of Notice and Demand. The Guarantor hereby waives
notice of acceptance of this Preferred Securities Guarantee and of any liability
to which it applies or may apply, presentment, demand for payment, any right to
require a proceeding first against the Issuer or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.


                                       15
<PAGE>   19
         SECTION 5.03. Obligations Not Affected. 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 Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

          (b) 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 Issuer granting indulgence or extension of any
kind;

          (c) 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 debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

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

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

          (f) 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 5.03 that the obligations of the Guarantor with respect to the
Guarantee Payments shall be absolute and unconditional under any and all
circumstances. There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

         SECTION 5.04. 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 any proceeding for any remedy available to
the Preferred Securities Guarantee Trustee in respect of this Preferred
Securities Guarantee or exercising any trust or power conferred upon the
Preferred Securities Guarantee Trustee under this Preferred Securities
Guarantee.

          (b) If the Preferred Securities Guarantee Trustee fails to enforce
this Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
rights of such Holder under this Preferred Securities Guarantee, without first
instituting a legal


                                       16
<PAGE>   20
proceeding against the Issuer, the Preferred Securities Guarantee Trustee or any
other person or entity. The Guarantor waives any right or remedy to require that
any action be brought first against the Issuer or any other person or entity
before proceeding directly against the Guarantor.

         Notwithstanding the foregoing, if the Guarantor has failed to make a
required Guarantee Payment, a Holder of Preferred Securities may directly
institute a proceeding against the Guarantor for enforcement of this Preferred
Securities Guarantee for such Guarantee Payment.

         SECTION 5.05.  Guarantee of Payment.  This Preferred Securities
Guarantee creates a guarantee of payment and not of collection.

         SECTION 5.06. Subrogation. The Guarantor shall be subrogated to all (if
any) rights of the Holders of Preferred Securities against the Issuer 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 5.07. Independent Obligations. The Guarantor acknowledges that
its obligations hereunder are independent of the obligations of the Issuer 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 (f), inclusive, of Section 5.03
hereof.

common and preferred stock), (ii) make any payment of principal, interest or
premium, if any, on or repay or repurchase or redeem any debt securities of the
Guarantor (including any Other Debentures) that rank pari passu with or junior
in right of payment to the Debentures or (iii) make any guarantee payments with
respect to any guarantee by the Guarantor of the debt securities of any
subsidiary of the Guarantor (including Other Guarantees) if such guarantee ranks
pari passu or junior in right of payment to the Debentures (other than (a)
dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Guarantor; (b) any
declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto; (c)
payments under the Preferred Securities Guarantee; (d) as a result of a
reclassification of the Guarantor's capital stock or the exchange or the
conversion of one class or series of the Guarantor's capital stock for another
class or series of the Guarantor's capital stock; (e) the purchase of fractional
interests in shares of the Guarantor's capital stock pursuant to the conversion
or exchange provisions of such capital stock or the security being converted or
exchanged; and (f) purchases of common stock related to the issuance of common
stock or rights under any of the Guarantor's benefit and compensation plans for
its directors, officers or employees or any of the Guarantor's dividend
reinvestment plans) if at such time (i) there shall have occurred any event of
which the Guarantor has actual knowledge that is, or with the giving of notice
or the lapse of time, or both, would be an Event of Default or (ii) the
Guarantor shall be in default with respect to its payment obligations under this
Preferred Securities Guarantee.

         SECTION 6.02. Ranking. This Preferred Securities Guarantee will
constitute an unsecured obligation of the Guarantor and will rank (i)
subordinate and junior in right of payment to all other liabilities of the
Guarantor except any liabilities (including the Other Guarantees, the Common
Securities Guarantee and the Other Common Securities Guarantees) that may be
pari passu or junior expressly by their terms, and (ii) senior to the
Guarantor's capital stock now or hereafter issued by the Guarantor, if any, and
with any guarantee now or hereafter entered into by the Guarantor in respect of
any preferred or preference stock of any Affiliate of the Guarantor. The
foregoing subordination shall not apply to amounts payable under Article 8.

terminate upon (i) full payment of the Redemption Price of all Preferred
Securities, or (ii) liquidation of the Issuer, the full payment of the amounts
payable in accordance with the Trust Agreement or the distribution of the
Debentures to the Holders of all of the Preferred Securities. Notwithstanding
the foregoing, this Preferred Securities Guarantee will continue to be effective

Preferred Securities must restore payment of any sums paid under the Preferred
Securities or under this Preferred Securities Guarantee.

lien or charge on any Guarantee Payments as a result of any amount due to it
under this Preferred Securities Guarantee.

of Holders will be required), this Preferred Securities Guarantee may only be
amended with the prior approval of the Holders of a Majority in Liquidation
Amount of the outstanding Preferred Securities (including the amount payable on
redemption, liquidation or otherwise, plus accumulated and unpaid Distributions
to the date upon which the voting percentages are determined). The provisions of
Section 12.2 of the Trust Agreement with respect to meetings of Holders of the
Securities apply to the giving of such approval. Except in connection with any
permitted merger or consolidation of the Guarantor with or into another entity
or any permitted sale, transfer or lease of the Guarantor's assets to another
entity (as described in Article 5 of the Indenture), the Guarantor may not
assign its rights or delegate its obligations under the Common Securities
Guarantee without the prior approval of the Holders of at least a Majority in
Liquidation Amount of the Common Securities then outstanding.

respect of the 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 Agreement shall also not be waivable; or

                  (ii) requires the consent or vote of greater than a majority
         in aggregate principal amount of the holders of the Subordinated Notes
         (a "SUPER MAJORITY") to be waived under the Indenture, the Event of
         Default under the Agreement may only be waived by the vote of the
         Holders of at least the proportion in aggregate Liquidation Amount of

                                       17
<PAGE>   23
         Securities that the relevant Super Majority represents of the aggregate
         principal amount of the Subordinated Notes outstanding.

The foregoing provisions of this Section 2.06(a) 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 Agreement 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 Agreement, 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 Agreement 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 Agreement as provided below in this Section
         2.06(b)), the Event of Default under the Agreement 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 Agreement as provided below
         in this Section 2.06(b), the Event of Default under the Agreement may
         only be waived by the vote of the Holders of at least the proportion in
         aggregate Liquidation Amount of the Common Securities that the relevant
         Super Majority represents of the aggregate principal amount of the
         Subordinated Notes outstanding;

provided further, 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,


                                       18
<PAGE>   24
the Property 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 Property Trustee in accordance with the terms
of the Securities. The foregoing provisions of this Section 2.06(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 Agreement and the Securities, as
permitted by the Trust Indenture Act. Subject to the foregoing provisions of
this Section 2.06(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 Agreement, 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
Property Trustee, at the direction of the Holders of the Preferred Securities,
constitutes a waiver of the corresponding Event of Default under this Agreement.
The foregoing provisions of this Section 2.06(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 Agreement and the
Securities, as permitted by the Trust Indenture Act.

         SECTION 2.07. Event of Default; Notice. (a) The Property Trustee shall,
within 90 days after the occurrence of any default with respect to the
Securities, transmit by mail, first class postage prepaid, to the Holders of the
Securities and to the Sponsor, notices of all such defaults actually known to a
Responsible Officer of the Property Trustee, unless such defaults have been
cured before the giving of such notice (the term "DEFAULTS" for the purposes of
this Section 2.07(a) being hereby defined to be a Default as defined in the
Indenture, not including any periods of grace provided for 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 Subordinated Notes, the Property Trustee shall be
protected in withholding such notice if and so long as a committee of
Responsible Officers of the Property Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of the Securities.

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

                  (i) a default under Sections 6.01(a) and 6.01(b) of the
         Indenture; or


                                       19
<PAGE>   25
              (ii) any default as to which the Property Trustee shall have
         received written notice or of which a Responsible Officer of the
         Property Trustee charged with the administration of the Agreement shall
         have actual knowledge.

          (c) Within ten Business Days after the occurrence of any Event of
Default actually known to a Responsible Officer of the Property Trustee, the
Property Trustee shall transmit notice of such Event of Default to the Holders
of the Preferred Securities, the Administrative Trustees and the Sponsor, unless
such Event of Default shall have been cured, waived or otherwise eliminated. The
Sponsor and the Administrative Trustees shall file annually with the Property
Trustee a certification as to whether or not they are in compliance with all the
conditions and covenants applicable to them under this Agreement.

         ownership of, or beneficial interest in, the Trust other than the
         Securities;

                  (vii) so long as any Subordinated Notes are held by the
         Property Trustee, the Trustees shall not (A) direct the time, method
         and place of conducting any proceeding with respect to any remedy
         available to the Subordinated Note Trustee, or exercise any trust or
         power conferred upon the Subordinated Note Trustee with respect to the
         Subordinated Notes, (B) waive any past default that is not waivable
         under the Indenture, (C) exercise any right to rescind or annul any
         declaration of acceleration of the maturity of the principal of the
         Subordinated Notes or (D) consent to any amendment, modification or
         termination of the Indenture or the Subordinated Notes where such
         consent shall be required, without, in each case, obtaining the prior
         approval of the Holders of a Majority in Liquidation Amount of all
         outstanding Securities of the Trust; provided, however, that where a
         consent under the Indenture would require the consent of each holder of
         Subordinated Notes affected thereby, no such consent shall be given by
         the Property Trustee without (1) the prior approval of each Holder of
         Securities and (2) a reasoned Opinion of Counsel delivered to the Trust
         from tax counsel experienced in such matters to the effect that the
         Trust will not be classified as an association taxable as a corporation
         for United States federal income tax purposes on account of such
         action;

                  (viii) shall not revoke any action previously authorized or
         approved by a vote of the Holders of Preferred Securities except by
         subsequent vote of such Holders; or

                  (ix) shall not revoke any action previously authorized or
         approved by a vote of the Holders of Common Securities except by
         subsequent vote of such Holders.

         SECTION 3.08. Powers and Duties of the Property Trustee. (a) The legal
title to the Subordinated Notes shall be owned by and held of record in the name
of the Property Trustee in trust for the benefit of the Trust and the Holders of
the Securities. The right, title and interest of the Property Trustee to the
Subordinated Notes shall vest automatically in each Person who may hereafter be
appointed as Property Trustee in accordance with Section 5.07. Such vesting and
cessation of title shall be effective whether or not conveyancing documents with
regard to the Subordinated Notes have been executed and delivered.


                                       25
<PAGE>   31
          (b) The Property Trustee shall not transfer its right, title and
interest in the Subordinated Notes to the Administrative Trustees or to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

          (c)   The Property Trustee shall:

                  (i) establish and maintain a segregated non-interest bearing
         trust account (the "PROPERTY TRUSTEE ACCOUNT") in the name of and under
         the exclusive control of the Property Trustee on behalf of the Holders
         of the Securities and, upon the receipt of payments of funds made in
         respect of the Subordinated Notes held by the Property Trustee, deposit
         such funds into the Property Trustee Account and make payments or cause
         the Paying Agent to make payments to the Holders of the Preferred
         Securities and Holders of the Common Securities from the Property
         Trustee Account in accordance with Section 6.01. Funds in the Property
         Trustee Account shall be held uninvested until disbursed in accordance
         with this Agreement;

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

                  (iii) upon written notice of the occurrence of a Special Event
         distribution issued by the Administrative Trustees in accordance with
         the terms of the Securities, engage in such ministerial activities as
         shall be necessary or appropriate to effect the distribution of the
         Subordinated Notes to Holders of Securities upon the occurrence of
         certain events (as may be defined in the terms of the Securities); and

                  (iv) take such ministerial action as may be requested by the
         Administrative Trustees in connection with the winding up of the
         affairs of or liquidation of the Trust in accordance with this
         Agreement and the preparation, execution and filing of a certificate of
         cancellation or other appropriate certificates with the Secretary of
         State of the State of Delaware and other appropriate governmental
         authorities.

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

          (e) Subject to Section 3.09(a), the Property Trustee shall take any
Legal Action which arises out of or in connection with an Event of Default of
which a


                                       26
<PAGE>   32
Responsible Officer of the Property Trustee has actual knowledge or the Property
Trustee's duties and obligations under this Agreement or the Trust Indenture Act
and, if the Property Trustee shall have failed to take such Legal Action, the
Holders of the Preferred Securities may, to the fullest extent permitted by law,
take such Legal Action, to the same extent as if such Holders of Preferred
Securities held an aggregate principal amount of Subordinated Notes equal to the
aggregate Liquidation Amount of such Preferred Securities, without first
proceeding against the Property Trustee or the Trust; provided however, that if
an Event of Default has occurred and is continuing and such event is
attributable to the failure of the Subordinated Note Issuer to pay the principal
of or premium, if any, or interest on the Subordinated Notes on the date such
principal, premium, if any, or interest 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 premium, if any, or interest on the Subordinated Notes 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
Indenture or in the Subordinated Notes (a "DIRECT ACTION"). In connection with
such Direct Action, the Subordinated Note Issuer shall remain obligated to pay
the principal of, premium, if any, or interest on such Subordinated Notes, and
the Common Securities Holder shall be subrogated to the rights of such Holder of
Preferred Securities to the extent of any payment made by the Subordinated Note
Issuer to such Holder in such Direct Action. Except as provided in the preceding
sentences, the Holders of Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the Subordinated Notes.

          (f) The Property Trustee shall continue to serve as a Trustee until
either:

                  (i) the Trust has been completely liquidated and the proceeds
         of the liquidation distributed to the Holders of Securities pursuant to
         the terms of the Securities and this Agreement; or

                  (ii) a successor Property Trustee has been appointed and has
         accepted that appointment in accordance with Section 5.07 (a "SUCCESSOR
         PROPERTY TRUSTEE").

          (g) The Property Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Subordinated Notes under the
Indenture and, if an Event of Default actually known to a Responsible Officer of
the Property Trustee occurs and is continuing, the Property Trustee shall, for
the benefit of Holders of the Securities, enforce its rights as holder of the
Subordinated Notes subject to the rights of the Holders pursuant to the terms of
the Securities and this Agreement.

<PAGE>   33
          (h) The Property Trustee shall be authorized to undertake any actions
set forth in Section 317(a) of the Trust Indenture Act.

          (i) For such time as the Property Trustee is the Paying Agent, the
Property Trustee may authorize one or more Persons to act as additional Paying
Agents and to pay Distributions, redemption payments or liquidation payments on
behalf of the Trust with respect to all Securities and any such Paying Agent
shall comply with Section 317(b) of the Trust Indenture Act. Any such additional
Paying Agent may be removed by the Property Trustee at any time the Property
Trustee remains as Paying Agent and a successor Paying Agent or additional
Paying Agents may be (but are not required to be) appointed at any time by the
Property Trustee while the Property Trustee is acting as Paying Agent.

          (j) Subject to this Section 3.08, the Property Trustee shall have none
of the duties, liabilities, powers or the authority of the Administrative
Trustees set forth in Section 3.06.

         Notwithstanding anything expressed or implied to the contrary in this
Agreement or any Annex or Exhibit hereto, the Property Trustee must exercise the
powers set forth in this Section 3.08 in a manner that is consistent with the
purposes and functions of the Trust set out in Section 3.03.

         SECTION 3.09. Certain Duties and Responsibilities of the Property
Trustee. (a) The Property 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 as are specifically set forth in
this Agreement and in the Securities and no implied covenants or obligations
shall be read into this Agreement against the Property Trustee. In case an Event
of Default has occurred (that has not been cured or waived pursuant to Section
2.06) of which a Responsible Officer of the Property Trustee has actual
knowledge, the Property Trustee shall exercise such of the rights and powers
vested in it by this Agreement, and use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

          (b) No provision of this Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, its own bad faith or its own willful misconduct, except that:

                  (i) 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:


                                       28
<PAGE>   34
                       (A) the duties and obligations of the Property Trustee
                  shall be determined solely by the express provisions of this
                  Agreement and in the Securities and the Property Trustee shall
                  not be liable except for the performance of such duties and
                  obligations as are specifically set forth in this Agreement
                  and in the Securities, and no implied covenants or obligations
                  shall be read into this Agreement against the Property
                  Trustee; and

                       (B) in the absence of bad faith on the part of the
                  Property Trustee, the Property 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 Property Trustee and conforming to the
                  requirements of this Agreement; provided, however, that in the
                  case of any such certificates or opinions that by any
                  provision hereof are specifically required to be furnished to
                  the Property Trustee, the Property Trustee shall be under a
                  duty to examine the same to determine whether or not they
                  conform to the requirements of this Agreement (but shall not
                  be required to confirm or investigate the accuracy of
                  mathematical calculations or other facts stated therein);

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

                  (iii) the Property 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 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
         Property Trustee, or exercising any trust or power conferred upon the
         Property Trustee under this Agreement;

                  (iv) no provision of this Agreement shall require the Property
         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 Agreement or
         indemnity reasonably satisfactory to the Property Trustee against such
         risk or liability is not reasonably assured to it;


                                       29
<PAGE>   35
                  (v) the Property Trustee's sole duty with respect to the
         custody, safekeeping and physical preservation of the Subordinated
         Notes and the Property Trustee Account shall be to deal with such
         property in a similar manner as the Property Trustee deals with similar
         property for its own account, subject to the protections and
         limitations on liability afforded to the Property Trustee under this
         Agreement and the Trust Indenture Act;

                  (vi) the Property Trustee shall have no duty or liability for
         or with respect to the value, genuineness, existence or sufficiency of
         the Subordinated Notes or the payment of any taxes or assessments
         levied thereon or in connection therewith;

                  (vii) the Property 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 Property Trustee need
         not be segregated from other funds held by it except in relation to the
         Property Trustee Account maintained by the Property Trustee pursuant to
         Section 3.08(c)(i) and except to the extent otherwise required by law;
         and

                  (viii) the Property Trustee shall not be responsible for
         monitoring the compliance by the Administrative Trustees or the Sponsor
         with their respective duties under this Agreement, nor shall the
         Property Trustee be liable for any default or misconduct of the
         Administrative Trustees or the Sponsor.

         SECTION 3.10.  Certain Rights of Property Trustee.  (a) Subject to the
provisions of Section 3.09:

                  (i) the Property Trustee may conclusively 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 Administrative
         Trustees contemplated by this Agreement may be sufficiently evidenced
         by an Officers' Certificate;

                  (iii) whenever in the administration of this Agreement, the
         Property Trustee shall deem it desirable that a matter be proved or
         established before taking, suffering or omitting any action hereunder,
         the Property Trustee (unless other evidence is herein specifically
         prescribed)


                                       30
<PAGE>   36
         may, in the absence of bad faith on its part, request and conclusively
         rely upon an Officers' Certificate which, upon receipt of such request,
         shall be promptly delivered by the Sponsor or the Administrative
         Trustees;

                  (iv) the Property 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 re-recording, refiling or registration thereof;

                  (v) the Property Trustee may consult with counsel or other
         experts of its selection 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; and the Property
         Trustee shall have the right at any time to seek instructions
         concerning the administration of this Agreement from any court of
         competent jurisdiction;

                  (vi) the Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Agreement at
         the request or direction of any Holder, unless such Holder shall have
         provided to the Property Trustee security and indemnity, reasonably
         satisfactory to the Property Trustee, against the costs, expenses
         (including reasonable attorneys' fees and expenses and the expenses of
         the Property 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 Property Trustee;

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

                  (viii) the Property Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through agents, custodians, nominees or attorneys and the Property
         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;


                                       31
<PAGE>   37
                  (ix) any action taken by the Property Trustee or its agents
         hereunder shall bind the Trust and the Holders of the Securities, and
         the signature of the Property 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 Property
         Trustee to so act or as to its compliance with any of the terms and
         provisions of this Agreement, both of which shall be conclusively
         evidenced by the Property Trustee's or its agent's taking such action;

                  (x) whenever in the administration of this Agreement the
         Property Trustee shall deem it desirable to receive instructions with
         respect to enforcing any remedy or right or taking any other action
         hereunder, the Property Trustee (i) 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 Property Trustee under the terms of
         the Securities in respect of such remedy, right or action, (ii) may
         refrain from enforcing such remedy or right or taking such other action
         until such instructions are received, and (iii) shall be protected in
         conclusively relying on, or acting in accordance with, such
         instructions;

                  (xi) except as otherwise expressly provided by this Agreement,
         the Property Trustee shall not be under any obligation to take any
         action that is discretionary under the provisions of this Agreement;
         and

                  (xii) the Property Trustee shall not be liable for any action
         taken, suffered, or omitted to be taken by it in good faith, without
         negligence, and reasonably believed by it to be authorized or within
         the discretion or rights or powers conferred upon it by this Agreement.

          (b) No provision of this Agreement shall be deemed to impose any duty
or obligation on the Property 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 Property 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 Property Trustee shall be
construed to be a duty.

          (c) It is expressly understood and agreed by the parties hereto that

Trust, (i) any agreements or instruments executed or delivered by The Chase
Manhattan Bank are executed and delivered not in its individual capacity but

Securities) shall The Chase Manhattan Bank in its individual capacity be
personally liable for the payment of any indebtedness or expenses of the Trust
or be liable for the breach or failure of any obligation, representation,
warranty, or covenant made or undertaken by the Trust under this Agreement
except if such breach or failure is due to any negligence, bad faith or wilful
misconduct of the Property Trustee.

         SECTION 3.11. Delaware Trustee. (a) Notwithstanding any other provision
of this Agreement other than Section 5.02, the Delaware Trustee shall not be
entitled to exercise any powers, nor shall the Delaware Trustee have any of the

misconduct of the Delaware Trustee.

         SECTION 3.12. Execution of Documents. Except as otherwise required by
the Business Trust Act or applicable law, each Administrative Trustee,
individually, is authorized to execute and deliver on behalf of the Trust any

         SECTION 3.13. Not Responsible for Recitals or Issuance of Securities.
The recitals contained in this Agreement and the Securities shall be taken as
the statements of the Sponsor, and the Trustees do not assume any responsibility
for their correctness. The Trustees make no representations as to the value or

lease its properties and assets as an entirety or substantially as an entirety
to any Person, except as described in Section 3.15(b) and 3.15(c) and except
with respect to the distribution of all Subordinated Notes to Holders of
Securities pursuant to Section 8.01(a)(iii) or Section 4 of Annex I.

          (b) The Trust may, at the request of the Sponsor, with the consent of
the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees and without the consent of the Holders of the
Securities, the Delaware Trustee or the Property Trustee, merge with or into,
convert into, consolidate, amalgamate, or be replaced by, or convey, transfer or
lease its properties and assets as an entirety or substantially as an entirety
to, a trust organized as such under the laws of any State; provided that:

                  (i) such successor entity (the "SUCCESSOR ENTITY") either:

                           (A) expressly assumes all of the obligations of the
                  Trust under the Securities; or

                           (B) substitutes for the Securities other securities
                  having substantially the same terms as the Securities (the
                  "SUCCESSOR SECURITIES") so long as the Successor Securities
                  rank the same as the Securities rank with respect to
                  Distributions and payments upon liquidation, redemption and
                  otherwise;

                  (ii) the Sponsor expressly appoints a trustee of the Successor
         Entity that possesses the same powers and duties as the Property
         Trustee with respect to the Subordinated Notes;

                  (iii) the Successor Securities (excluding any securities
         substituted for any Common Securities) are listed, quoted or included
         for trading, or


                                       34
<PAGE>   40
         any Successor Securities will be listed, quoted or included for
         trading, upon notification of issuance, on any organization on which
         the Preferred Securities are then listed, quoted or included;

                  (iv) such merger, conversion, consolidation, amalgamation,
         replacement, conveyance, transfer or lease does not cause the Preferred
         Securities (including any Successor Securities) or the Subordinated
         Notes to be downgraded or placed under surveillance or review by any
         nationally recognized statistical rating organization that publishes a
         rating on the Preferred Securities or the Subordinated Notes;

                  (v) such merger, conversion, consolidation, amalgamation,
         replacement, conveyance, transfer or lease does not adversely affect
         the rights, preferences and privileges of the Holders of the Securities
         (including the Holders of any Successor Securities) in any material
         respect (other than with respect to any dilution of the interests of
         such Holders or Holder of Successor Securities, as the case may be, in
         the Successor Entity);

                  (vi) the Successor Entity has a purpose substantially
         identical to that of the Trust;

                  (vii) prior to such merger, conversion, consolidation,
         amalgamation, replacement, conveyance, transfer or lease, the Sponsor
         has received an opinion of a nationally recognized independent counsel
         to the Trust experienced in such matters to the effect that:

                       (A) such merger, conversion, consolidation, amalgamation,
                  replacement, conveyance, transfer or lease does not adversely
                  affect the rights, preferences and privileges of the Holders
                  of the Securities (including the Holders of any Successor
                  Securities) in any material respect (other than with respect
                  to any dilution of the interests of such Holders or Holders of
                  Successor Securities, as the case may be, in the Successor
                  Entity); and

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

                  (viii) the Sponsor or any permitted successor or assignee owns
         all of the common securities of the Successor Entity and guarantees the
         obligations of the Successor Entity under the Successor Securities at
         least


                                       35

         to the extent provided by the Preferred Securities Guarantee and the
         Common Securities Guarantee.

          (c) Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in Liquidation Amount of the Securities, merge
with or into, convert into, consolidate, amalgamate, or be replaced by, or
convey, transfer or lease its properties and assets as an entirety or
substantially as an entirety to, any other Person or permit any other Person to
merge with or into, consolidate, amalgamate, or replace it if such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease would
cause the Trust or the Successor Entity, if any, not to be classified as a
grantor trust for United States Federal income tax purposes.

         SECTION 4.01. Sponsor's Purchase of Common Securities. At the Closing
Time, the Sponsor will purchase all of the Common Securities then issued by the
Trust, in an amount equal to at least 3% of the total capital of the Trust, at
the same time as the Preferred Securities are issued and sold. The aggregate
Liquidation Amount of Common Securities at any time shall not be less than 3% of
the capital of the Trust.

         SECTION 4.02. Covenants of the Common Securities Holder. For so long as
the Preferred Securities remain outstanding, the Holder of the Common Securities
shall covenant (i) to maintain, directly or indirectly, 100% ownership of the
Common Securities; provided, however, that any permitted successor of the Holder
of the Common Securities under the Indenture may succeed to such Holder's
interest in the Common Securities, (ii) to cause the Trust to remain a statutory
business trust, except in connection with a distribution of Subordinated Notes
to the Holders of Securities, the redemption of all of the Securities, or
certain mergers, consolidations, conversions or amalgamations, each as permitted
by this Agreement, and not to voluntarily dissolve, wind up, liquidate or be
terminated, except as permitted by this Agreement, (iii) to use its commercially
reasonable efforts to ensure that the Trust shall not be an investment company
for purposes of the Investment Company Act, and (iv) to take no action which
would be reasonably likely to cause the Trust to be classified as an association
or a publicly traded partnership taxable as a corporation for United States
federal income tax purposes.

          (d) determine the jurisdictions in which to take appropriate action to
qualify or register for sale all or part of the Preferred Securities and to do
any and all such acts, other than actions which must be taken by the Trust, and

<PAGE>   43
          (a) at any time before the issuance of any Securities, the Sponsor
may, by written instrument, increase or decrease the number of Trustees; and

          (b) after the issuance of any Securities, the number of Trustees may
be increased or decreased by vote of the Holders of a Majority in Liquidation
Amount of the Common Securities voting as a class at a meeting of the Holders of
the Common Securities;

provided, however, that, the number of Trustees shall in no event be less than
two (2); provided, further, that (1) one Trustee shall be a Person meeting the
requirements of Section 5.02 (the "DELAWARE TRUSTEE"); (2) there shall be at
least one Trustee who is an employee or officer of, or is affiliated with the
Sponsor (an "ADMINISTRATIVE TRUSTEE"); and (3) one Trustee shall be the Property
Trustee, and such Trustee may also serve as Delaware Trustee if it meets the
applicable requirements. Notwithstanding the above, unless an Event of Default
shall have occurred and be continuing, at any time or times, for the purpose of
meeting the legal requirements of the Trust Indenture Act or of any jurisdiction
in which any part of the Trust's property may at the time be located, the
Holders of a Majority in Liquidation Amount of the Common Securities acting as a

either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in such capacity any
property, title, right or power deemed necessary or desirable, subject to the
provisions of this Agreement. In case an Event of Default has occurred and is

          (b) if not a natural person, an entity which has its principal place
of business in the State of Delaware, and otherwise meets the requirements of
applicable law,

provided, however, if the Property Trustee has its principal place of business
in the State of Delaware and otherwise meets the requirements of applicable law,
then the Property Trustee shall also be the Delaware Trustee and Section 3.11
shall have no application.

         subject to supervision or examination by federal, state, territorial or
         District of Columbia authority. If such corporation publishes reports
         of 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 5.03(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 Property Trustee shall cease to be eligible to
so act under Section 5.03(a), the Property Trustee shall immediately resign in
the manner and with the effect set forth in Section 5.07(c).

          (c) If the Property Trustee has or shall acquire any "CONFLICTING
INTEREST" within the meaning of Section 310(b) of the Trust Indenture Act, the
Property Trustee and the Holder of the Common Securities (as if it were the
obligor referred to in Section 310(b) of the Trust Indenture Act) shall in all
respects comply with the proviso of Section 310(b) of the Trust Indenture Act.

          (d) The Preferred Securities Guarantee shall be deemed to be
specifically described in this Agreement for purposes of clause (i) of the first
provision contained in Section 310(b) of the Trust Indenture Act.

<PAGE>   46
                  (i) without cause until the issuance of any Securities, by
         written instrument executed by the Sponsor;

                  (ii) unless an Event of Default shall have occurred and be

         of the Holders of a Majority in Liquidation Amount of the Preferred

         remove or replace the Administrative Trustees, which voting rights are
         exclusively vested in the Holder of the Common Securities); and

                  (iv) if an Event of Default shall have occurred and be
         continuing after the issuance of the Securities, with respect to the
         Property Trustee or the Delaware Trustee, by vote of Holders of a
         Majority in Liquidation Amount of the Preferred Securities voting as a
         class at a meeting of Holders of the Preferred Securities.

          (b) (i) The Trustee that acts as Property Trustee shall not be removed
in accordance with Section 5.07(a) until a Successor Property Trustee has been
appointed and has accepted such appointment by written instrument executed by
such Successor Property Trustee and delivered to the Administrative Trustees and
the Sponsor; and

                  (ii) the Trustee that acts as Delaware Trustee shall not be
         removed in accordance with Section 5.07(a) until a successor Trustee
         possessing the qualifications to act as Delaware Trustee under Sections
         5.02 and 5.04 (a "SUCCESSOR DELAWARE TRUSTEE") has been appointed and
         has accepted such appointment by written instrument executed by such
         Successor Delaware Trustee and delivered to the removed Delaware
         Trustee, the Property Trustee (if the removed Delaware Trustee is not

         Sponsor.

          (c) A Trustee appointed to office shall hold office until his
successor shall have been appointed or until his death, removal or resignation.
Any Trustee may resign from office (without need for prior or subsequent
accounting) by an instrument in writing signed by the Trustee and delivered to
the other Trustees,


                                       41
<PAGE>   47
the Sponsor and the Trust, which 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 Property
         Trustee shall be effective:

                       (A) until a Successor Property Trustee has been appointed
                  and has accepted such appointment by instrument executed by
                  such Successor Property Trustee and delivered to the Trust,
                  the Sponsor, the Delaware Trustee (if the resigning Property
                  Trustee is not also the Delaware Trustee) and the resigning
                  Property Trustee; or

                       (B) until the assets of the Trust have been completely
                  liquidated and the proceeds thereof distributed to the Holders
                  of the Securities; and

         (ii) no such resignation of the Trustee that acts as the Delaware
         Trustee shall be effective until a Successor Delaware Trustee has been
         appointed and has accepted such appointment by instrument executed by
         such Successor Delaware Trustee and delivered to the Trust, the
         Property Trustee (if the resigning Delaware Trustee is not also the
         Property Trustee), the Sponsor and the resigning Delaware Trustee.

          (d) The Holders of the Common Securities or, if an Event of Default
shall have occurred and be continuing after the issuance of the Securities, the
Holders of the Preferred Securities shall use their best efforts to promptly
appoint a Successor Delaware Trustee or Successor Property Trustee, as the case
may be, if the Property Trustee or the Delaware Trustee delivers an instrument
of resignation in accordance with this Section 5.07.

          (e) If no Successor Property Trustee or Successor Delaware Trustee
shall have been appointed and accepted appointment as provided in this Section
5.07 within 60 days after delivery of an instrument of resignation or removal,
the Property Trustee or Delaware Trustee resigning or being removed, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper and
prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be.

          (f) No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

         SECTION 5.08. Vacancies among Trustees. If a Trustee ceases to hold
office for any reason and the number of Trustees is not reduced pursuant to
Section 5.01, or if the number of Trustees is increased pursuant to Section
5.01, a vacancy shall occur. A resolution certifying the existence of such
vacancy by the Administrative Trustees or, if there are more than two, a
majority of the Administrative Trustees shall be conclusive evidence of the
existence of such vacancy. The vacancy shall be filled with a Trustee appointed
in accordance with Section 5.07.

         SECTION 5.09. Effect of Vacancies. The death, resignation, retirement,
removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to
perform the duties of a Trustee shall not operate to dissolve, terminate or
annul the Trust or to terminate this Agreement. Whenever a vacancy in the number
of Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 5.07, the
Administrative Trustees in office, regardless of their number, shall have all
the powers granted to the Administrative Trustees and shall discharge all the
duties imposed upon the Administrative Trustees by this Agreement.

         SECTION 5.10. Meetings. If there is more than one Administrative
Trustee, meetings of the Administrative Trustees shall be held from time to time
upon the call of any Administrative Trustee. Regular meetings of the
Administrative Trustees may be held at a time and place fixed by resolution of
the Administrative Trustees. Notice of any in-person meetings of the
Administrative Trustees shall be hand delivered or otherwise delivered in
writing (including by facsimile, with a hard copy by overnight courier) not less
than 24 hours before such meeting. Notice of any telephonic meetings of the
Administrative Trustees or any committee thereof shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 24 hours before a meeting. 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 an Administrative
Trustee at a meeting shall constitute a waiver of notice of such meeting except
where an Administrative Trustee attends a meeting for the express purpose of
objecting to the transaction of any activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this
Agreement, any action of the Administrative Trustees may be taken at a meeting
by vote of a majority of the Administrative 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 majority written consent of the
Administrative Trustees. In the event there is only one Administrative Trustee,
any and all action of such Administrative Trustee shall be evidenced by a
written consent of such Administrative Trustee.

         SECTION 5.11. Delegation of Power. (a) Any Administrative Trustee may,
by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing
any documents contemplated in Section 3.06, including any registration statement
or amendment thereto filed with the Commission; and

          (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of this Agreement.

         SECTION 5.12. Merger, Conversion, Consolidation or Succession to
Business. Any Person into which the Property Trustee or the Delaware Trustee or
any Administrative Trustee that is not a natural person, as the case may be, may
be merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which the Property
Trustee or the Delaware Trustee, as the case may be, shall be a party, or any
Person succeeding to all or substantially all the corporate trust business of
the Property Trustee or the Delaware Trustee, as the case may be, shall be the
successor of the Property Trustee or the Delaware Trustee, as the case may be,
hereunder, provided such Person 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; provided, however, such successor shall
notify the Sponsor and the Trust promptly of its succession.

         SECTION 5.13.  Compensation.  The Sponsor agrees:

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

          (b) to reimburse the Property Trustee and the Delaware Trustee upon
their request for reasonable expenses, disbursements and advances incurred or
made by the Property Trustee or the Delaware Trustee, respectively, in
accordance with any provision of this Agreement (including the reasonable
compensation and the expenses and advances of its agents and counsel), except
any such expense or advance as may be attributable to their negligence, willful
misconduct or bad faith.

          DISTRIBUTIONS; RESET RATE; REMARKETING; MANDATORY REDEMPTION

         SECTION 6.01. Distributions. Holders shall receive Distributions in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Securities in accordance with the respective
terms and preferences set forth below and in Annex I. If and to the extent that
the Subordinated Note Issuer makes a payment of interest (including Additional
Interest (as defined in the Indenture)), premium and/or principal on the
Subordinated Notes held by the Property Trustee (the amount of any such payment
being a "PAYMENT AMOUNT"), the Property Trustee shall and is directed, to the
extent funds are available for that purpose, to make a distribution (a
"DISTRIBUTION") of the Payment Amount to Holders.

         SECTION 6.02. Determination of Reset Date; Remarketing Procedures. (a)
Subject to Sections 6.04 and 6.06, the Reset Date shall be September 28, 1999
(the "EXPECTED RESET DATE"); provided that

                  (i) the Sponsor may, by notice to the Remarketing Agent,
         direct that the Reset Date be delayed if the Sponsor believes it will
         be unable to meet the conditions to Remarketing in the absence of such
         a delay; and

                  (ii) the Remarketing Agent may, by notice to the Sponsor,
         direct that the Reset Date be delayed if the Remarketing Agent believes
         that a Remarketing will not be successful in the absence of such a
         delay;

and, in either such event, the Sponsor and the Remarketing Agent will use their
best efforts to establish a delayed Reset Date that is within five Business Days
after the Expected Reset Date, but in no event later than the Final Reset Date;
and provided further, that no Reset Date may be established if any Default (as
defined in the Credit Agreement) has occurred, except in connection with a
Remarketing following a Cured Default Trigger Event pursuant to Section 6.06. If
the Sponsor and the Remarketing Agent have not agreed, on or prior to the sixth
Business Day preceding the Final Reset Date, to a Reset Date that is not later
than the Final Reset Date, no Remarketing shall occur and the Securities shall
be redeemed at the Mandatory Redemption Price on the Mandatory Redemption Date.

          (b) The Sponsor shall, by notice to the Remarketing Agent no later
than five Business Days prior to the Reset Date, select and specify at least
three but no more than five Reference Corporate Dealers. By 3:00 p.m., New York
City time, on the Reset Date, the Remarketing Agent shall request Bids from such
Reference


                                       45
<PAGE>   51
Corporate Dealers. The Remarketing Agent shall determine the lowest Bid Rate
(the "WINNING BID RATE") from among the Bids obtained on the Reset Date. By
approximately 4:30 p.m., New York City time, on the Reset Date, the Remarketing
Agent shall notify the Sponsor, the Underwriter, the Indenture Trustee and the
Property Trustee of the Winning Bid Rate. If on a Reset Date, Bids are not
submitted by at least two Reference Corporate Dealers, or if the lowest Bid
submitted would result in a Winning Bid Rate in excess of the rate permitted by
applicable law, such Remarketing shall be deemed to be a Failed Remarketing on
the corresponding Remarketing Settlement Date. The Winning Bid Rate determined
by the Remarketing Agent, absent manifest error, shall be binding and conclusive
upon the Holders of the Trust Securities, the Sponsor and the Trust.

          (c) On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "SECONDARY PURCHASER") the Reference Corporate Dealer
providing the Bid containing the Winning Bid Rate. If the Winning Bid Rate is
specified in the Bids submitted by two or more Reference Corporate Dealers, the
Remarketing Agent shall, in its sole discretion, designate one of such
Reference Corporate Dealers as the Secondary Purchaser.

          (d) On the Reset Date, the Secondary Purchaser shall enter into a
Secondary Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate Liquidation Amount of Preferred Securities,
with a Distribution Rate equal to the Winning Bid Rate and with a Mandatory
Redemption Date on the Maturity Extension Date.

          (e) If a Remarketing has occurred pursuant to this Section 6.02 but
settlement of the purchase and sale of the Preferred Securities does not occur
on the corresponding Remarketing Settlement Date, then, unless the provisions of
Section 6.04 with respect to a Renewed Remarketing shall apply, a Failed
Remarketing shall be deemed to occur on such Remarketing Settlement Date.

          (f) At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay to the Remarketing Agent on behalf
of the Holders of the Preferred Securities on the Remarketing Settlement Date,
an amount of cash equal to the Remarketing Price.

          (g) Unless otherwise agreed among the Remarketing Agent, the Paying
Agent and any Former Holder, the Remarketing Agent shall pay the Remarketing
Price, less the Remarketing Fee, to the Paying Agent, acting solely as agent for
the Former Holders, and the Paying Agent shall promptly pay such amounts to the
Former Holders on the Remarketing Settlement Date in the same manner as is
specified in Section 5(g) of Annex I hereto for payments with respect to


                                       46
<PAGE>   52
Redemptions of the Preferred Securities. Any amounts held by the Paying Agent
for payment to the Former Holders shall not be property of the Trust.

          (h) The obligation of the Remarketing Agent to make payment to the
Former Holders in connection with the Remarketing shall be limited to the extent
that the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

          (i) Any outstanding Preferred Securities purchased on the Remarketing
Settlement Date shall be deemed to be transferred to the Secondary Purchaser and
shall be replaced in the manner provided in Section 6.02(j). On and after the
Remarketing Settlement Date (except in the event of a Failed Remarketing), the
Trust shall make no further payments to, and the Trust shall have no further
obligations under this Agreement in respect of, the Holders of such replaced
Preferred Securities (the "FORMER HOLDERS"), the Trust shall only be obligated
to make payments to the Holders of Replacement Securities, and the Preferred
Securities of the Former Holders shall no longer represent an obligation of or
interest in the Trust but shall only represent a right to receive the proceeds
of the Remarketing from the Paying Agent.

          (j) The Sponsor shall cause replacement certificates evidencing the
remarketed Preferred Securities to be executed by an Administrative Trustee on
behalf of the Trust and authenticated by the Property Trustee in accordance with
the provisions of Section 7.03 (the "REPLACEMENT SECURITIES"). The Replacement
Securities shall be delivered to the purchaser or purchasers of the remarketed
Preferred Securities in accordance with the terms of the Secondary Purchase
Agreement.

         SECTION 6.03. Reset of Distribution Rate and Mandatory Redemption Date.
Unless a Failed Remarketing shall have occurred, from and including the Reset
Settlement Date, the Distribution Rate on the Securities shall be the Winning
Bid Rate and the Mandatory Redemption Date shall be the Maturity Extension Date.

         SECTION 6.04. Renewed Remarketing. If a Remarketing has occurred
pursuant to Section 6.02 that would be a Failed Remarketing solely pursuant to
Section 6.02(e), because the purchase and sale of the Preferred Securities does
not take place on the corresponding Remarketing Settlement Date, and the reason
for such failure shall, in the good faith determination of the Remarketing Agent
(made after consultation with the Sponsor), result from facts or circumstances
that are not due to the action or inaction of the Sponsor, then the provisions
of Sections 6.02 and 6.06 shall apply to a second remarketing (a "RENEWED
REMARKETING") of the Preferred Securities, except that the Expected Reset Date


                                       47
<PAGE>   53
shall be the sixth Business Day following such corresponding Remarketing
Settlement Date; provided that the provisions of this Section 6.04 shall be
applied only once.

         SECTION 6.05. Failed Remarketing; Mandatory Redemption. The Remarketing
Agent shall give notice of any Failed Remarketing on the date such Failed
Remarketing occurs or is deemed to occur, by 4:00 p.m., New York City time, on
the date of such Failed Remarketing, to the Subordinated Note Issuer, the
Property Trustee, the Indenture Trustee, the Underwriter and the Paying Agent
under the Indenture. In the case of any Failed Remarketing, the Subordinated
Notes shall be redeemed by the Subordinated Note Issuer, pursuant to Section
3.04 of the Supplemental Indenture, on the third Business Day following the date
such Failed Remarketing occurs or is deemed to occur, and the proceeds of such
redemption shall be simultaneously applied by the Property Trustee to redeem a
Like Amount of the Securities at the Mandatory Redemption Price on a Pro Rata
basis in the manner provided in Section 5 of Annex I.

         SECTION 6.06. Early Remarketing. If any of the following events (each,
a "TRIGGER EVENT") shall have occurred:

          (a) the Closing Price of the Common Stock on any Trading Day, as
determined by the Remarketing Agent, is less than the Trigger Price (a "STOCK
PRICE TRIGGER EVENT");

          (b) a Cross Default shall have occurred but such Cross Default shall
have ceased to be continuing (a "CURED DEFAULT TRIGGER EVENT"); or

          (c) the Sponsor (i) shall have made a written request to the
Underwriter to enter into a firm commitment underwriting of the Common Stock,
and the Sponsor and the Underwriter shall have substantially agreed to the terms
of such underwriting in the manner described in Section 12 of the Forward
Underwriting Agreement or (ii) shall have given notice to accelerate the
Commencement Date in the manner described in Section 7 of the Forward
Underwriting Agreement (an "UNDERWRITING TRIGGER EVENT");

then a Remarketing shall occur pursuant to Section 6.02 and, if applicable,
Section 6.04, except that:

           (A) the Expected Reset Date shall be the sixth Business Day following
the date such Trigger Event first occurs;

           (B) in the case of a Stock Price Trigger Event or a Cured Default
Trigger Event, the Final Reset Date shall be the 15th day following the date
such Trigger


                                       48
<PAGE>   54
Event occurs, or the 20th day in the case of a Renewed Remarketing to which the
provisions of Section 6.04 apply, but in no event later than the third scheduled
Trading Day prior to November 10, 1999;

           (C) in the case of an Underwriting Trigger Event, the Final Reset
Date shall be the 45th day following the date such Trigger Event occurs, but in
no event later than the third scheduled Trading Day prior to November 10, 1999;
and

           (D) notwithstanding the provisions of clauses (A), (B) and (C) above,
if a Reset Date has already been established or a Remarketing has already taken
place at the time such Trigger Event occurs, the Remarketing shall occur on such
established Reset Date or settled on the corresponding Remarketing Settlement
Date.

         SECTION 6.07. Adjustments to Trigger Price. The "TRIGGER PRICE" shall
initially be $22 11/16 (twenty-two and eleven-sixteenths). Following the
determination by the Calculation Agent in its reasonable discretion that a
Potential Adjustment Event has occurred, the Calculation Agent shall determine
(after consultation with the Sponsor) whether such Potential Adjustment Event
has a diluting or concentrative effect on the theoretical value of the Common
Stock and, if so, shall make the corresponding adjustment(s), if any, to the
Trigger Price. The Sponsor shall promptly notify the Calculation Agent of any
Potential Adjustment Event. The Calculation Agent may, but need not, determine
the appropriate adjustment(s) by reference to the adjustment(s) in respect of
such Potential Adjustment Event made by an options exchange to options on the
Common Stock traded on that options exchange. In the event of any merger,
consolidation or reorganization of the Sponsor, the Calculation Agent shall
determine the appropriate Trigger Price as a result of such event.



                                    ARTICLE 7
                             ISSUANCE OF SECURITIES

         SECTION 7.01. General Provisions Regarding Securities. (a) The
Administrative Trustees shall on behalf of the Trust issue one class of
preferred securities representing undivided beneficial interests in the assets
of the Trust having such terms as are set forth in Annex I (the "PREFERRED
SECURITIES") and one class of common securities representing undivided
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "COMMON SECURITIES"). The Trust shall issue no securities
or other interests in the assets of the Trust other than the Preferred
Securities and the Common Securities.


                                       49
<PAGE>   55
          (b) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

          (c) Upon issuance of the Securities as provided in this Agreement, the
Securities so issued shall be validly issued, fully paid and non-assessable.

          (d) Every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Agreement, shall
(i) be deemed to have expressly assented and agreed to the terms of, and shall
be bound by, this Agreement, including the terms of Annex I, Exhibits A-1, A-2,
A-3 and D and (ii) be deemed to have expressly appointed the Remarketing Agent
as its attorney-in-fact with respect to the transactions contemplated by the
Secondary Purchase Agreement.

         SECTION 7.02. Execution and Authentication. (a) The Securities shall be
signed on behalf of the Trust by an Administrative Trustee. In case any
Administrative Trustee of the Trust who shall have signed any of the Securities
shall cease to be such Administrative Trustee before the Securities so signed
shall be delivered by the Trust, such Securities nevertheless may be delivered
as though the Person who signed such Securities had not ceased to be such
Administrative Trustee; and any Securities may be signed on behalf of the Trust
by such persons who, at the actual date of execution of such Security, shall be
the Administrative Trustees of the Trust, although at the date of the execution
and delivery of this Agreement any such person was not an Administrative
Trustee.

          (b) One Administrative Trustee shall sign the Preferred Securities for
the Trust by manual or facsimile signature.

         A Preferred Security shall not be valid until authenticated by the
manual signature of an authorized signatory of the Property Trustee. The
signature shall be conclusive evidence that the Preferred Security has been
authenticated under this Agreement. A Common Security shall be valid upon
execution by an Administrative Trustee without any act of the Property Trustee.

         Upon a written order of the Trust signed by one Administrative Trustee,
the Property Trustee shall authenticate the Preferred Securities for original
issue.

         The aggregate number of Preferred Securities outstanding at any time
shall not exceed the number set forth in the terms in Annex I hereto except as
provided in Section 7.06.


                                       50
<PAGE>   56
         The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Preferred Securities. An authenticating agent may
authenticate Preferred Securities whenever the Property Trustee may do so. Each
reference in this Agreement to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee hereunder with respect to the Sponsor or an Affiliate.

         SECTION 7.03. Form and Dating. The Preferred Securities and the
Property Trustee's certificate of authentication shall be substantially in the
form of Exhibit A-1, the Replacement Securities shall be substantially in the
form of Exhibit A-3 and the Common Securities shall be substantially in the form
of Exhibit A-2, each of which is hereby incorporated in and expressly made a
part of this Agreement. The Preferred Securities shall be issued only in minimum
denominations of $100,000 Liquidation Amount and integral multiples of $1,000 in
excess thereof. The Securities may be in definitive or global form, and may be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to an Administrative Trustee, as evidenced by the
execution thereof. The Securities may have letters, CUSIP or other numbers,
notations or other marks of identification or designation and such legends or
endorsements required by law, stock exchange or quotation system rule,
agreements to which the Trust is subject, if any, or usage (provided that any
such notation, legend or endorsement is in a form acceptable to the Trust). An
Administrative Trustee, at the direction of the Sponsor, shall furnish any such
legend not contained in Exhibits A-1, A-2 or A-3 to the Property Trustee in
writing. Each Preferred Security shall be dated the date of its authentication.
The terms and provisions of the Securities set forth in Annex I and the forms of
Securities set forth in Exhibits A-1, A-2 and A-3 are part of the terms of this
Agreement and to the extent applicable, the Property Trustee and the Sponsor, by
their execution and delivery of this Agreement, expressly agree to such terms
and provisions and to be bound thereby.

          (a) The Preferred Securities shall initially be issued in definitive
form ("DEFINITIVE PREFERRED SECURITIES"). Upon Remarketing, the Preferred
Securities shall be issued as Replacement Securities in the form of one or more
permanent global Securities in definitive, fully registered form with the
appropriate global legends set forth in Exhibit A-3 hereto (a "GLOBAL PREFERRED
SECURITY"), which shall be deposited on behalf of the purchasers of the
Preferred Securities represented thereby with the Property Trustee, as custodian
for the Depository, and registered in the name of the Depository or a nominee of
the Depository, duly executed by an Administrative Trustee on behalf of the
Trust and authenticated by the Property Trustee as hereinafter provided. The
number of Preferred Securities represented by the Global Preferred Security may
from time to time be increased or decreased by adjustments made on the records
of the Property Trustee and the


                                       51
<PAGE>   57
Depository or its nominee as hereinafter provided. The Holder of a Global
Preferred Security may grant proxies and otherwise authorize any Person,
including Participants, and Persons that may hold interests through
Participants, to take any action which such Holder is entitled to take under
this Agreement or the Securities.

          (b) An Administrative Trustee shall execute and the Property Trustee
shall, in accordance with this Section 7.03, authenticate and make available for
delivery initially one or more Definitive Preferred Securities registered in the
name of the initial Holders or their designees. Upon Remarketing, an
Administrative Trustee shall execute and the Property Trustee shall, in
accordance with this Section 7.03, authenticate and make available for delivery
one or more Global Preferred Securities that (i) shall be registered in the name
of Cede & Co. or other nominee of such Depository and (ii) shall be delivered by
the Property Trustee to such Depository or pursuant to such Depository's written
instructions or held by the Property Trustee as custodian for the Depository.

          (c) Members of, or participants in, the Depository ("PARTICIPANTS")
shall have no rights under this Agreement with respect to any Global Preferred
Security held on their behalf by the Depository or by the Property Trustee as
the custodian of the Depository or under such Global Preferred Security, and the
Depository or its nominee may be treated by the Trust, the Property Trustee and
any agent of the Trust or the Property Trustee as the absolute owner of such
Global Preferred Security for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Trust, the Property Trustee or any
agent of the Trust or the Property Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depository or
impair, as between the Depository and its Participants, the operation of
customary practices of such Depository governing the exercise of the rights of
an owner of a beneficial interest in any Global Preferred Security.

          (d) Except in connection with the initial issuance of the Preferred
Securities and as further provided in Section 9.02, owners of beneficial
interests in a Global Preferred Security will not be entitled to receive
physical delivery of Definitive Preferred Securities.

         SECTION 7.04. Registrar and Paying Agent. The Trust shall maintain in
the Borough of Manhattan, The City of New York, (i) an office or agency where
Preferred Securities may be presented for registration of transfer ("REGISTRAR")
and (ii) an office or agency where Preferred Securities may be presented for
payment ("PAYING AGENT"). The Registrar shall keep a register of the Preferred
Securities and of their transfer. The Trust may appoint the Registrar and the
Paying Agent and may appoint one or more co-registrars and one or more


                                       52
<PAGE>   58
additional paying agents in such other locations as it shall determine. The term
"REGISTRAR" includes any additional registrar and the term "PAYING AGENT"
includes any additional paying agent. The Trust may change any Registrar or
Paying Agent without prior notice to any Holder. The Administrative Trustees
shall notify the Property Trustee of the name and address of any Agent not a
party to this Agreement. If the Trust fails to appoint or maintain another
entity as Registrar or Paying Agent, the Property Trustee shall act as such, and
as Paying Agent the Property Trustee shall have the rights set forth in Section
3.08(i). The Property Trustee or any of its Affiliates may act as Registrar or
Paying Agent. The Trust shall act as Registrar and Paying Agent for the Common
Securities.

         Any Paying Agent shall be permitted to resign as Paying Agent upon 30
days' prior written notice to the Property Trustee, the Administrative Trustees
and the Sponsor. In the event that the Property Trustee shall no longer be the
Paying Agent, the Trust shall appoint a successor Paying Agent (which shall be a
bank or trust company acceptable to the Sponsor) to act as Paying Agent. Any
such resignation shall become effective upon the appointment of a successor
paying agent by the Trust to perform the services that would otherwise be
performed hereunder by the Paying Agent and the agreement of any such successor
so to serve.

         The Trust initially appoints the Property Trustee as Registrar and
Paying Agent for the Preferred Securities.

         SECTION 7.05. Paying Agent to Hold Money in Trust. The Trust shall
require each Paying Agent other than the Property Trustee to agree in writing
that the Paying Agent will hold in trust for the benefit of Holders or the
Property Trustee all money held by the Paying Agent for the payment of
Liquidation Amounts or Distributions on the Securities and will notify the
Property Trustee if there are insufficient funds for such purpose. While any
such insufficiency continues, the Property Trustee may require a Paying Agent to
pay all money held by it to the Property Trustee. The Trust at any time may
require a Paying Agent to pay all money held by it to the Property Trustee and
to account for any money disbursed by it. Upon payment over to the Property
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 7.06. Replacement of Securities. If a Holder of a Security
claims that a Security owned by it has been lost, destroyed or wrongfully taken
or if such Security is mutilated and is surrendered to the Trust or, in the case
of the Preferred Securities, to the Property Trustee, an Administrative Trustee
shall execute and


                                       53
<PAGE>   59
the Property Trustee shall authenticate and make available for delivery a
replacement of such Security if the Property Trustee's and the Trust's
requirements, as the case may be, are met. An indemnity bond must be provided by
the Holder which, in the judgment of the Property Trustee, is sufficient to
protect the Trustees, the Sponsor or any authenticating agent from any loss
which any of them may suffer if a Security is replaced. The Trust may charge
such Holder for its expenses in replacing a Security.

         SECTION 7.07. Outstanding Preferred Securities. The Preferred
Securities outstanding at any time are all the Preferred Securities
authenticated by the Property Trustee except for those canceled by it, those
delivered to it for cancellation, and those described in this Section as not
outstanding.

         If a Preferred Security is replaced, paid or purchased pursuant to
Section 7.06 hereof, it ceases to be outstanding unless the Property 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 Agreement, including any Preferred Securities replaced by
Replacement Securities in accordance with the provisions of Article 6, they
cease to be outstanding and Distributions thereon shall cease to accumulate.

         Except to the extent set forth in the last paragraph of Section 6 of
Annex I and Section 7.08, a Preferred Security does not cease to be outstanding
because the Trust, the Sponsor or an Affiliate of the Sponsor holds such
Preferred Security.

         SECTION 7.08. Preferred Securities in Treasury. In determining whether
the Holders of the required amount of Preferred 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 Property Trustee shall be fully protected in relying on any such
direction, waiver or consent, only Preferred Securities which a Responsible
Officer of the Property Trustee actually knows are so owned shall be so
disregarded.

         SECTION 7.09. Temporary Securities. Until Definitive Securities are
ready for delivery, the Administrative Trustees may prepare and, in the case of
the Preferred Securities, the Property Trustee shall authenticate temporary
Securities. Temporary Securities shall be substantially in the form of
Definitive Securities but may have variations that the Trust considers
appropriate for temporary Securities. Without unreasonable delay, the
Administrative Trustees shall prepare


                                       54
<PAGE>   60
and, in the case of the Preferred Securities, the Property Trustee shall
authenticate Definitive Securities in exchange for temporary Securities.

         SECTION 7.10. Cancellation. The Trust at any time may deliver Preferred
Securities to the Property Trustee for cancellation. The Registrar and Paying
Agent shall forward to the Property Trustee any Preferred Securities surrendered
to them for registration of transfer, redemption, exchange or payment. The
Property Trustee shall promptly cancel all Preferred Securities surrendered for
registration of transfer, redemption, exchange, payment, replacement or
cancellation and shall dispose of canceled Preferred Securities as the Trust
directs, provided that the Property Trustee shall not be obligated to destroy
Preferred Securities. The Trust may not issue new Preferred Securities to
replace Preferred Securities that it has paid or redeemed or that have been
delivered to the Property Trustee for cancellation or that any Holder has
exchanged.

         SECTION 7.11. CUSIP Numbers. The Trust, in issuing the Preferred
Securities, may use "CUSIP" numbers (if then generally in use), and, if so, the
Property Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Holders of Preferred Securities; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Preferred 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 Preferred Securities, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Sponsor will
promptly notify the Property Trustee of any change in the CUSIP numbers.

         Section 3.14.

          (b) As soon as is practicable upon completion of winding up of the
Trust following the occurrence of an event referred to in Section 8.01(a), the

          (b) Subject to this Article 9, Preferred Securities shall be freely
transferable.


                                       56
<PAGE>   62
          (c) To the fullest extent permitted by law, the Sponsor may not
transfer the Common Securities except for any transfer (whether voluntarily or
by operation of law) permitted under Article 5 of the Indenture.

          (d) Each Security that bears or is required to bear the legend set
forth in this Section 9.01(d) (a "RESTRICTED SECURITY") shall be subject to the
restrictions on transfer provided in the legend set forth in this Section
9.01(d), unless such restrictions on transfer shall be waived by the written
consent of the Administrative Trustees, and the Holder of each Restricted
Security, by such Holder's acceptance thereof, agrees to be bound by such
restrictions on transfer. As used in this Section 9.01(d) and in Section
9.01(f), the terms "transfer" encompasses any sale, pledge, transfer or other
disposition of any Restricted Security.

         Prior to the Transfer Restriction Termination Date, any certificate
evidencing a Security shall bear a legend in substantially the following form,
unless otherwise agreed by the Administrative Trustees (with written notice
thereof to the Indenture Trustee):

         THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY
NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED
INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (2)
AGREES THAT IT WILL NOT PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE
TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES
ACT (OR ANY SUCCESSOR PROVISION) RESELL OR OTHERWISE TRANSFER THE SECURITIES
EVIDENCED HEREBY EXCEPT (A) TO HERCULES INCORPORATED OR ANY SUBSIDIARY THEREOF,
(B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
SECURITIES ACT OR (C) TO A SECONDARY PURCHASER (AS DEFINED IN THE AMENDED AND
RESTATED TRUST AGREEMENT OF HERCULES TRUST V DATED AS OF NOVEMBER 12, 1998 (AS
AMENDED FROM TIME TO TIME, THE "TRUST AGREEMENT")) THAT HAS ENTERED INTO A
SECONDARY PURCHASE AGREEMENT (AS DEFINED IN THE TRUST AGREEMENT) WITH THE TRUST,
(3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITIES EVIDENCED
HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND AND
(4) AGREES, WITH RESPECT TO ANY TRANSFER OCCURRING PRIOR TO THE REMARKETING DATE
ON


                                       57
<PAGE>   63
WHICH REPLACEMENT SECURITIES ARE ISSUED, TO PROVIDE TO THE PROPERTY TRUSTEE A
DULY EXECUTED CERTIFICATE SUBSTANTIALLY TO THE EFFECT OF CLAUSES (1), (2) AND
(3), ABOVE. THIS LEGEND WILL BE REMOVED AFTER THE EXPIRATION OF THE HOLDING
PERIOD APPLICABLE TO THE SALES OF THE SECURITIES EVIDENCED HEREBY UNDER RULE
144(K) UNDER THE SECURITIES ACT.

         Following the Transfer Restriction Termination Date, any Security or
Securities issued in exchange or substitution therefor (other than Securities
acquired by the Sponsor or any Affiliate), may upon surrender of such Security
or Securities for exchange to the Trustee in accordance with the provisions of
this Section 9.01(d), be exchanged for a new Security or Securities, as the case
may be, in a like aggregate Liquidation Amount that shall not bear the
restrictive legend required by this Section.

          (e) Any Security that, prior to the Transfer Restriction Termination
Date, is purchased or owned by the Sponsor or any Affiliate thereof may not be
resold by the Sponsor or such Affiliate unless registered under the Securities
Act or resold pursuant to an exemption from the registration requirements
thereof that results in such Security no longer being a "restricted security" as
defined under Rule 144 under the Securities Act.

          (f) The Preferred Securities may be transferred or exchanged only in
minimum denominations of $100,000 Liquidation Amount and integral multiples of
$1,000 in excess thereof, and any attempted transfer, sale or other disposition
of Preferred Securities in a denomination of less than $100,000 Liquidation
Amount shall be deemed to be void and of no legal effect whatsoever.

          (g) The Administrative Trustees shall provide for the registration of
Securities and of the transfer of Securities, which will be effected without
charge but only upon payment (with such indemnity as the Administrative 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
Securities, the Administrative Trustees shall cause one or more new Securities
to be issued in the name of the designated transferee or transferees. Every
Security surrendered for registration of transfer or exchange shall be
accompanied by a written instrument of transfer in form satisfactory to the
Administrative Trustees duly executed by the Holder or such Holder's attorney
duly authorized in writing. Each Security surrendered for registration of
transfer shall be canceled by the Administrative Trustees. A transferee of a
Security shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee of a Security. By
acceptance of a Security, each transferee shall be deemed to have agreed to be
bound by this Agreement.

         SECTION 9.02. Transfer Procedures and Restrictions. (a) When Definitive
Preferred Securities are presented to the Registrar:

                  (x) to register the transfer of such Definitive Preferred
         Securities; or

                  (y) to exchange such Definitive Preferred Securities which
         became mutilated, destroyed, defaced, stolen or lost, for an equal
         Liquidation Amount of Definitive Preferred Securities,

the Registrar shall register the transfer or make the exchange as requested if
its reasonable requirements for such transaction are met; provided, however,
that the Definitive Preferred Securities surrendered for transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form reasonably satisfactory to the Property Trustee and the Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing and
comply with Section 9.01(d) herein.

          (b) Transfer of a Definitive Preferred Security for a Beneficial
Interest in a Global Preferred Security. Upon receipt by the Property Trustee of
a Definitive Preferred Security, duly endorsed or accompanied by appropriate
instruments of transfer, in form satisfactory to the Property Trustee, and in
compliance with restrictions under Section 9.01(d), together with written
instructions directing the Property Trustee to make, or to direct the Depository
to make, an adjustment on its books and records with respect to the Global
Preferred Security to reflect an increase in the Liquidation Amount of the
Preferred Securities represented by such Global Preferred Security, then the
Property Trustee shall cancel such Definitive Preferred Security and cause, or
direct the Depository to cause, the aggregate Liquidation Amount of Preferred
Securities represented by the appropriate Global Preferred Security to be
increased accordingly. If no Global Preferred Securities are then outstanding,
an Administrative Trustee shall execute on behalf of the Trust shall issue and
the Property Trustee shall authenticate, upon written order of any
Administrative Trustee, a Global Preferred Security representing an appropriate
Liquidation Amount of Preferred Securities.

          (c) Transfer and Exchange of Global Preferred Securities. Subject to
Section 9.01(d) and Section 9.02(d), the transfer and exchange of Global
Preferred Securities or beneficial interests therein shall be effected through
the Depository, in accordance with this Agreement and the procedures of the
Depository therefor.

          (d) Transfer of a Beneficial Interest in a Global Preferred Security
for a Definitive Preferred Security.


                                       59
<PAGE>   65
                  (i) A Global Preferred Security deposited with the Depository
         or with the Property Trustee as custodian for the Depository pursuant
         to Section 7.03 shall be transferred to the beneficial owners thereof
         in the form of Definitive Preferred Securities only if such transfer
         complies with Sections 9.01(d), 9.02(c) and 9.02(e) and (A) the
         Depository notifies the Trust that it is unwilling or unable to
         continue as Depository for such Global Preferred Security or if at any
         time such Depository ceases to be a "clearing agency" registered under
         the Exchange Act and, in each case, a depository is not appointed by
         the Sponsor within 90 days of receipt of such notice or of becoming
         aware of such condition, (B) a Default or an Event of Default has
         occurred and is continuing or (C) the Administrative Trustees, on
         behalf of the Trust, at its sole discretion elects to cause the
         issuance of Definitive Preferred Securities.

                  (ii) Any Global Preferred Security that is transferable to the
         beneficial owners thereof in the form of Definitive Preferred
         Securities pursuant to this Section 9.02(d) shall be surrendered by the
         Depository to the Property Trustee to be so transferred, in whole or
         from time to time in part, without charge, and the Property Trustee
         shall authenticate and make available for delivery, upon such transfer
         of each portion of such Global Preferred Security, an equal aggregate
         Liquidation Amount of Securities of authorized denominations in the
         form of Definitive Preferred Securities. Any portion of a Global
         Preferred Security transferred pursuant to this Section shall be
         registered in such names as the Depository shall direct.

                  (iii) In the event of the occurrence of any of the events
         specified in Section 9.02(d)(i) above, the Administrative Trustees will
         promptly make available to the Property Trustee a reasonable supply of
         Definitive Preferred Securities in fully registered form without
         Distribution coupons.

          (e) Restrictions on Transfer and Exchange of Global Preferred
Securities. Notwithstanding any other provisions of this Agreement (other than
the provisions set forth in Section 9.01(d) and 9.02(d)), a Global Preferred
Security may not be transferred as a whole except by the Depository to a nominee
of the Depository or another nominee of the Depository or by the Depository or
any such nominee to a successor Depository or a nominee of such successor
Depository.

          (f) Cancellation or Adjustment of Global Preferred Security. At such
time as all beneficial interests in a Global Preferred Security have either been
exchanged for Definitive Preferred Securities to the extent permitted by this
Agreement or redeemed, repurchased or canceled in accordance with the terms of
this Agreement, such Global Preferred Security shall be returned to the
Depository for cancellation


                                       60
<PAGE>   66
or retained and canceled by the Property Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Preferred Security is
exchanged for Definitive Preferred Securities, Preferred Securities represented
by such Global Preferred Security shall be reduced and an adjustment shall be
made on the books and records of the Property Trustee (if it is then the
custodian for such Global Preferred Security) with respect to such Global
Preferred Security, by the Property Trustee or the Securities Custodian, to
reflect such reduction.

         (g) Obligations with Respect to Transfers and Exchanges of Preferred
Securities.

                  (i) To permit registrations of transfers and exchanges, an
         Administrative Trustee shall execute and the Property Trustee shall
         authenticate Definitive Preferred Securities and Global Preferred
         Securities at the Registrar's request in accordance with the terms of
         this Agreement.

                  (ii) Registrations of transfers or exchanges will be effected
         without charge, but only upon payment (with such indemnity as the Trust
         or the Sponsor may require) in respect of any tax or other governmental
         charge that may be imposed in relation to it.

                  (iii) The Registrar shall not be required to register the
         transfer of or exchange of (A) Preferred Securities during a period
         beginning at the opening of business 15 days before the day of mailing
         of a notice of redemption or any notice of selection of Preferred
         Securities for redemption and ending at the close of business on the
         day of such mailing; or (B) any Preferred Security so selected for
         redemption in whole or in part, except the unredeemed portion of any
         Preferred Security being redeemed in part.

                  (iv) All Preferred Securities issued upon any registration of
         transfer or exchange pursuant to the terms of this Agreement shall
         evidence the same security and shall be entitled to the same benefits
         under this Agreement as the Preferred Securities surrendered upon such
         registration of transfer or exchange.

         (h) No Obligation of the Property Trustee.

                  (i) The Property Trustee shall have no responsibility or
         obligation to any beneficial owner of a Global Preferred Security, a
         Participant in the Depository or other Person with respect to the
         accuracy of the records of the Depository or its nominee or of any
         Participant thereof, with respect to any ownership interest in the
         Preferred Securities or with respect to the delivery to any
         Participant, beneficial owner or other Person (other than the


                                       61
<PAGE>   67
         Depository) of any notice (including any notice of redemption) or the
         payment of any amount, under or with respect to such Preferred
         Securities. All notices and communications to be given to the Holders
         and all payments to be made to Holders under the Preferred Securities
         shall be given or made only to or upon the order of the Holders (which
         shall be the Depository or its nominee in the case of a Global
         Preferred Security). The rights of beneficial owners in any Global
         Preferred Security shall be exercised only through the Depository
         subject to the applicable rules and procedures of the Depository. The
         Property Trustee may conclusively rely and shall be fully protected in
         relying upon information furnished by the Depository or any agent
         thereof with respect to its Participants and any beneficial owners.

         (ii) The Property Trustee and Registrar shall have no obligation or
         duty to monitor, determine or inquire as to compliance with any
         restrictions on transfer imposed under this Agreement or under
         applicable law with respect to any transfer of any interest in any
         Preferred Security (including any transfers between or among
         Participants or beneficial owners in any Global Preferred Security)
         other than to require delivery of such certificates and other
         documentation or evidence as are expressly required by, and to do so if
         and when expressly required by, the terms of this Agreement, and to
         examine the same to determine substantial compliance as to form with
         the express requirements hereof.

         SECTION 9.03. Deemed Security Holders. The Trust, the Trustees, the
Registrar and the Paying Agent may treat the Person in whose name any Security
shall be registered on the books and records of the Trust as the sole owner and
Holder of such Security 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 Security on the part of any
Person other than such Holder, regardless of any notice to the contrary.

         SECTION 9.04. Book Entry Interests. (a) Unless and until Definitive
Preferred Securities have been issued to the Preferred Security Beneficial
Owners pursuant to Section 9.02:

                  (i) the provisions of this Section 9.04 shall be in full force
         and effect;

                  (ii) the Trust and the Trustees shall be entitled to deal with
         the Depository for all purposes of this Agreement (including the
         payment of Distributions on the Global Preferred Securities and
         receiving approvals, votes or consents hereunder) as the Holder of the
         Preferred Securities and the


                                       62
<PAGE>   68
         sole Holder of the Global Preferred Securities and shall have no
         obligation to the Preferred Security Beneficial Owners;

                  (iii) to the extent that the provisions of this Section 9.04
         conflict with any other provisions of this Agreement, the provisions of
         this Section 9.04 shall control; and

                  (iv) the rights of the Preferred Security Beneficial Owners
         shall be exercised only through the Depository and shall be limited to
         those established by law and agreements between such Preferred Security
         Beneficial Owners and the Depository and/or the Participants, including
         receiving and transmitting payments of Distributions on the Global
         Certificates to such Participants. The Depository will make book entry
         transfers among the Participants.

          (b) Any Global Preferred Security may be endorsed with or have
incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Agreement as may be required by the
Depository, by any exchange or by the National Association of Securities
Dealers, Inc. in order for the Preferred Securities to be tradeable on the
PORTAL Market or as may be required for the Preferred Securities to be tradeable
on any other market developed for trading of securities pursuant to Rule 144A or
required to comply with any applicable law or any regulation thereunder or with
the rules and regulations of any securities exchange upon which the Preferred
Securities may be listed or traded or to conform with any usage with respect
thereto, or to indicate any special limitations or restrictions to which any
particular Preferred Securities are subject.

         SECTION 9.05. Notices to Depository. Whenever a notice or other
communication to the Holders of Preferred Securities is required to be given by
a Trustee under this Agreement, such Trustee shall give all such notices and
communications specified herein to be given to the Holders of Global Preferred
Securities to the Depository and shall have no notice obligations to the
Preferred Security Beneficial Owners.

         SECTION 9.06. Appointment of Successor Depository. If any Depository
elects to discontinue its services as securities depositary with respect to the
Preferred Securities, the Administrative Trustees may, in their sole discretion,
appoint a successor Depository with respect to the Preferred Securities.

      LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

         SECTION 10.01.  Liability.

          (a) Except as expressly set forth in this Agreement, 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; and

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

          (b) The Sponsor 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 extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         SECTION 10.02. 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
Agreement or by law, except that this provision will not be deemed to modify
Section 3.09.

          (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon 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 10.03. 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 Agreement shall not be liable to the Trust
or to any other Covered Person for its good faith reliance on the provisions of
this Agreement. The provisions of this Agreement, 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 Property 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
         any Covered Person and any Indemnified Person; or

                  (ii) whenever this Agreement 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 Agreement or any
other agreement contemplated herein or of any duty or obligation of the
Indemnified Person at law or in equity or otherwise.

         (c) Whenever in this Agreement 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


                                       65

         subject to any other or different standard imposed by this Agreement or
         by applicable law.

         SECTION 10.04.  Indemnification.

          (a) (i) The Sponsor 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 and
expenses), 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.

                  (ii) The Sponsor 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 and expenses)
         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 Company Indemnified 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


                                       66
<PAGE>   72
         liability) in defense of any action, suit or proceeding referred to in
         paragraphs (i) and (ii) of this Section 10.04(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 10.04(a) (unless ordered by a court) shall be made by the
         Sponsor 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 Administrative Trustees by a majority vote of a Quorum
         consisting of such Administrative 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 Administrative
         Trustees so directs, by independent legal counsel in a written opinion,
         or (3) by the Common Security Holder of the Trust.

                  (v) Expenses (including attorneys' fees and expenses) incurred
         by a Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in Sections 10.04(a)(i) and 10.04(a)(ii) shall be paid by the Sponsor
         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 Sponsor as
         authorized in this Section 10.04(a). Notwithstanding the foregoing, no
         advance shall be made by the Sponsor if a determination is reasonably
         and promptly made (A) by the Administrative Trustees by a majority vote
         of a Quorum of disinterested Administrative Trustees, (B) if such a
         Quorum is not obtainable, or, even if obtainable, if a quorum of
         disinterested Administrative Trustees so directs, by independent legal
         counsel in a written opinion or (C) by the Common Security Holder of
         the Trust, that, based upon the facts known to the Administrative
         Trustees, counsel or the Common Security Holder 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 Administrative
         Trustees, independent legal counsel or Common Security Holder
         reasonably determine that such person deliberately breached his duty to
         the Trust or its Common or Preferred Security Holders.

                  (vi) The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section
         10.04(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 Sponsor or Preferred Security Holders 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 10.04(a) shall be deemed to be
         provided by a contract between the Sponsor and each Company Indemnified
         Person who serves in such capacity at any time while this Section
         10.04(a) is in effect. Any repeal or modification of this Section
         10.04(a) shall not affect any rights or obligations then existing.

                  (vii) The Sponsor 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 Sponsor would have the power to indemnify him against such
         liability under the provisions of this Section 10.04(a).

                  (viii) For purposes of this Section 10.04(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 10.04(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 10.04(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) Property Trustee, (ii) the
Delaware Trustee, (iii) any Affiliate of the Property Trustee and the Delaware
Trustee, and (iv) any officers, directors, shareholders, members, partners,
employees, representatives, custodians, nominees or agents of the Property
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


                                       68
<PAGE>   74
Person harmless against, any and all loss, liability, damage, claim or expense
including taxes (other than taxes based on the income of such Fiduciary
Indemnified Person) incurred without gross negligence, bad faith or willful
misconduct on its part (or such other standard otherwise provided, in the case
of the Property Trustee, in the Trust Indenture Act), arising out of or in
connection with the acceptance or administration of the trust or trusts
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 with respect to the Property Trustee, this provision shall not be
deemed to modify Section 3.09(b) or the Trust Indenture Act. The obligation to
indemnify as set forth in this Section 10.04(b) shall survive the resignation or
removal of the Property Trustee or the Delaware Trustee and the satisfaction and
discharge of this Agreement.

         SECTION 10.05. Outside Businesses. Any Covered Person, the Sponsor, the
Delaware Trustee and the Property Trustee subject to Section 5.03 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 Agreement 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 Property
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 Property 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 Property 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.

                                   ACCOUNTING

         SECTION 11.01. Fiscal Year. The fiscal year ("FISCAL YEAR") of the
Trust shall be the calendar year, or such other year as is required by the Code.

<PAGE>   75
         SECTION 11.02. Certain Accounting Matters. (a) At all times during the
existence of the Trust, the Administrative 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 of the Trust by a firm of
independent certified public accountants selected by the Administrative
Trustees.

          (b) The Administrative 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 Administrative 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 Administrative Trustees shall
endeavor to deliver all such information statements within 60 days after the end
of each Fiscal Year of the Trust.

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

         SECTION 11.03. 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 Subordinated Notes held by the
Property Trustee shall be made directly to the Property Trustee Account and no
other funds of the Trust shall be deposited in the Property Trustee Account. The
sole signatories for such accounts shall be designated by the Administrative
Trustees; provided, however, that the Property Trustee shall designate the
signatories for the Property Trustee Account.

         SECTION 11.04. Withholding. The Trust and the Administrative Trustees
shall comply with all withholding requirements under United States Federal,
state


                                       70
<PAGE>   76
and local law. The Administrative Trustees, on behalf of 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 Administrative Trustees to assist them in determining the extent of, and in
fulfilling, the Trust's withholding obligations. The Administrative Trustees
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 claim of excess withholding, 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.

                             AMENDMENTS AND MEETINGS

         SECTION 12.01. Amendments. (a) Except as otherwise provided in this
Agreement or by any applicable terms of the Securities, this Agreement may only
be amended by a written instrument approved and executed by:

                  (i) the Sponsor and the Administrative Trustees (or, if there
         are more than two Administrative Trustees, a majority of the
         Administrative Trustees);

                  (ii) if the amendment affects the rights, powers, duties,
         obligations or immunities of the Property Trustee, the Property
         Trustee; and

                  (iii) if the amendment affects the rights, powers, duties,
         obligations or immunities of the Delaware Trustee, the Delaware
         Trustee.

          (b) No amendment shall be made, and any such purported amendment shall
be void and ineffective:

                  (i) unless, in the case of any proposed amendment, the
         Property Trustee shall have first received an Officers' Certificate
         from each of the Trust and the Sponsor that such amendment is permitted
         by, and conforms to, the terms of this Agreement (including the terms
         of the Securities);


                                       71
<PAGE>   77
                  (ii) unless, in the case of any proposed amendment which
         affects the rights, powers, duties, obligations or immunities of the
         Property Trustee, the Property Trustee shall have first received:

                       (A) an Officers' Certificate from each of the Trust and
                  the Sponsor that such amendment is permitted by, and conforms
                  to, the terms of this Agreement (including the terms of the
                  Securities); and

                       (B) an opinion of counsel (who may be counsel to the
                  Sponsor or the Trust) that such amendment is permitted by, and
                  conforms to, the terms of this Agreement (including the terms
                  of the Securities) and that all conditions precedent to the
                  execution and delivery of such amendment have been satisfied;
                  and

                  (iii) to the extent the result of such amendment would:

                       (A) cause the Trust to fail to be classified for purposes
                  of United States Federal income taxation as a grantor trust;

                       (B) reduce or otherwise adversely affect the powers of
                  the Property Trustee in contravention of the Trust Indenture
                  Act; or

                       (C) cause the Trust to be deemed to be an Investment
                  Company required to be registered under the Investment Company
                  Act.

          (c) At such time after the Trust has issued any Securities that remain
outstanding, any amendment that would adversely affect the rights, privileges or
preferences of any Holder of the Securities may be effected only with such
additional requirements as may be set forth in the terms of such Securities;
provided, however, that, without the consent of each Holder of the Securities,
this Agreement may not be amended to (i) change the Distribution Rate (or manner
of calculation of the Distribution Rate), amount, timing or currency or
otherwise adversely affect the method of any required payment, (ii) change the
purposes of the Trust, (iii) authorize the issuance of any additional beneficial
interests in the Trust, (iv) change the redemption provisions, (v) change the
conditions precedent for the Sponsor to elect to dissolve the Trust and
distribute the Subordinated Notes to the Holders of the Securities, (vi) change
the Liquidation Distribution or other provisions relating to the distribution of
amounts payable upon the dissolution and liquidation of the Trust, (vii) affect
the limited liability of any Holder of the Securities or (viii) restrict the
right of a Holder of the Securities to institute suit for the enforcement of any
required payment on or after the due date therefor (or, in the case of a
redemption, on the redemption date).

<PAGE>   78
          (d) Article 6, Section 9.01(c) and this Section 12.01 shall not be
amended without the consent of all of the Holders of the Securities.

          (e) Article 4 shall not be amended without the consent of the Holders
of a Majority in Liquidation Amount of the Common Securities.

          (f) The rights of the Holders of the Common Securities under Article 5
to increase or decrease the number of, and to appoint and remove, Trustees shall
not be amended without the consent of the Holders of a Majority in Liquidation
Amount of the Common Securities.

          (g) Notwithstanding Section 12.01(c), this Agreement may be amended by
the Sponsor and the Trustees without the consent of the Holders of the
Securities to:

                  (i) cure any ambiguity, correct or supplement any provision in
         this Agreement that may be inconsistent with any other provision of
         this Agreement or to make any other provisions with respect to matters
         or questions arising under this Agreement not inconsistent with any
         other provisions of this Agreement; and

                  (ii) modify, eliminate or add to any provisions of this
         Agreement to such extent as shall be necessary to ensure that the Trust
         will be classified for United States Federal income tax purposes as a
         grantor trust at all times that any Securities are outstanding or to
         ensure that the Trust will not be required to register as an Investment
         Company under the Investment Company Act;

      provided, however, that, in each case, such action shall not adversely
affect in any material respect the interests of the Holders of the Securities,
and any such amendments of this Agreement shall become effective when notice
thereof is given to the Holders of the Securities.

         SECTION 12.02. 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 Administrative 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 Agreement, the terms of
the Securities or the rules of any stock exchange or quotation system or market
on which the Preferred Securities are listed or admitted for trading. The
Administrative 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 the
Securities of such class. Such direction shall be given by delivering to the
Administrative Trustees one or more notices in a writing stating that the
signing Holders of Securities wish to call a meeting and indicating the


                                       73
<PAGE>   79
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 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) Whenever a vote, consent or approval of the Holders of Securities
is permitted or required under this Agreement or the rules of any stock exchange
or quotation system or market on which the Preferred Securities are listed or
admitted 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.

          (c) 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. The
         Administrative 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
         Administrative 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 eleven 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, all matters relating to the giving, voting or validity of
         proxies shall be governed by the General Corporation Law of the State
         of Delaware relating to proxies, and judicial interpretations
         thereunder, as if the Trust were a Delaware corporation and the Holders
         of the Securities were stockholders of a Delaware corporation;


                                       74
<PAGE>   80
                  (iii) each meeting of the Holders of the Securities shall be
         conducted by the Administrative Trustees or by such other Person that

                     AUCTION RATE RESET PREFERRED SECURITIES
                      AUCTION RATE RESET COMMON SECURITIES

         Pursuant to Section 7.01 of the Amended and Restated Trust Agreement,
dated as of November 12, 1998 (as amended from time to time, the "AGREEMENT"),
the designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Preferred Securities and the Common Securities
(collectively, the "SECURITIES") are set out below (each capitalized term used
but not defined herein has the meaning set forth in the Agreement or, if not
defined in such Agreement, as defined in the Indenture):

           1.   Designation and Number.

          (a) Preferred Securities. 200,000 Auction Rate Reset Preferred
Securities of the Trust, with an aggregate Liquidation Amount with respect to
the assets of the Trust of Two Hundred Million dollars ($200,000,000), and with
a Liquidation Amount with respect to the assets of the Trust of $1,000 per
security, are hereby designated for the purposes of identification only as
"PREFERRED SECURITIES" (the "PREFERRED SECURITIES"). The Preferred Securities
shall be issued only in minimum denominations of $100,000 Liquidation Amount and

the Preferred Securities shall initially be substantially in the form of Exhibit

shall be substantially in the form of Exhibit A-3 to the Agreement, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice or to conform to the rules of any stock
exchange or quotation system on which the Preferred Securities are listed or

           2.   Distributions.

          (a) Distributions with respect to the Liquidation Amount of $1,000 per
Security (the "LIQUIDATION AMOUNT") of each Security will accrue and be payable
at a rate (the "DISTRIBUTION RATE") (such rate being the rate of interest
payable on the Subordinated Notes to be held by the Property Trustee) per annum
equal to

                  (i) from and including the date of issuance to but excluding
         the date such Securities are redeemed, LIBOR plus 175 basis points,
         compounded quarterly;

                  (ii) from and including the Remarketing Settlement Date on
         which Replacement Securities are issued to but excluding the date such
         Securities are redeemed, the Winning Bid Rate, compounded quarterly;
         and

                  (iii) notwithstanding clauses (i) and (ii) above, if the
         Securities are not redeemed because the Company fails to pay the
         principal amount of the Subordinated Notes on the date such amount
         becomes due, then from and including such due date to but excluding the
         date the Securities are redeemed, the Default Rate, compounded
         quarterly, but only to the extent permitted by applicable law.

Distributions that are not paid when due will bear additional distributions
thereon compounded quarterly at the applicable periodic Distribution Rate
specified above (to the extent permitted by applicable law). Distributions are
payable if and to the extent the Subordinated Note Issuer makes a payment of
Additional Interest (as defined in the Indenture) upon the occurrence of certain
events specified in the Indenture. The term "DISTRIBUTIONS", as used herein,
includes any such additional distributions unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Subordinated Notes held by the Property Trustee and to the extent the
Property Trustee has funds on hand legally available therefor.

          (b) Until the Remarketing Settlement Date on which Replacement
Securities are issued, Distributions on the Securities will be cumulative, will
be payable quarterly in arrears on February 12, May 12, August 12 and November
12 of each year, commencing February 12, 1999, and on such Remarketing
Settlement Date (each, a "PRE-REMARKETING DISTRIBUTION DATE"), will accumulate
from and including the most recent date to which Distributions have been paid
or, if no Distributions have been paid, from November 12, 1998, to but excluding
the related Pre-Remarketing Distribution Date, except as otherwise described
below.

         The Distribution Rate in effect for the period from and including
November 12, 1998 to but excluding February 12, 1999 shall be the rate
determined by the Calculation Agent two London Banking Days prior to November
12, 1998 and shall equal LIBOR plus 175 basis points. The Distribution Rate in
effect thereafter, for


                                       I-2
<PAGE>   90
each quarterly period from and including the immediately preceding
Pre-Remarketing Distribution Date to but excluding the applicable
Pre-Remarketing Distribution Date, shall be determined by the Calculation Agent
two London Banking Days prior to such immediately preceding Pre-Remarketing
Distribution Date and shall equal LIBOR plus 175 basis points. The amount of
Distributions payable for any quarterly period shall be computed on the basis of
a 360-day year of twelve 30-day months. Except as provided in the last sentence
of this paragraph, the amount of Distributions payable for any period shorter
than a full quarterly period for which Distributions are computed will be
computed on the basis of the actual number of days elapsed per 30-day month. If
a Pre-Remarketing Distribution Date is not a Business Day, then such
Pre-Remarketing Distribution Date will be the next succeeding Business Day,
except if such Business Day is in the next succeeding calendar month, such
Pre-Remarketing Distribution Date will be the immediately preceding Business
Day.

         As used herein, "LONDON BANKING DAY" means any day on which dealings in
deposits in U.S. Dollars are transacted in the London interbank market.

          (c) From and including the Remarketing Settlement Date on which
Replacement Securities are issued, Distributions on the Replacement Securities
and on the Common Securities will be cumulative, will be payable quarterly in
arrears on February 12, May 12, August 12 and November 12 of each year,
commencing on the Remarketing Settlement Date, and on the Mandatory Redemption
Date (each, a "DISTRIBUTION DATE"), will accumulate from the most recent date to
which Distributions have been paid or, if no Distributions have been paid, from
and including the Remarketing Settlement Date, to but excluding the related
Distribution Date, except as otherwise described below. The amount of
Distributions payable for any quarterly period shall be computed on the basis of
a 360-day year of twelve 30-day months. Except as provided in the last sentence
of this paragraph, the amount of Distributions payable for any period shorter
than a full quarterly period for which Distributions are computed will be
computed on the basis of the actual number of days elapsed per 30-day month. If
a Distribution Date is not a Business Day, then such Distribution Date will be
the next succeeding Business Day, except if such Business Day is in the next
succeeding calendar month, such Distribution Date will be the immediately
preceding Business Day.

          (d) Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the fifteenth
day prior to each Pre-Remarketing Distribution Date or Distribution Date, as the
case may be. Subject to any applicable laws and regulations and the provisions
of the Agreement, each such payment in respect of the Preferred Securities will
be made in respect of any global certificate representing Securities, to the
Depository (or other applicable Depository), which shall credit the relevant
accounts at the Depository (or such other Depository) on the applicable payment
dates, or in respect of Securities in certified form, by check mailed to the
address of the Holder entitled thereto as such address


                                      I-3
<PAGE>   91
shall appear on the register; provided, however, that at the written request of
any Holder of at least $10,000,000 aggregate Liquidation Amount of Preferred
Securities received by the Property Trustee not later than the fifteenth day
prior to the applicable Pre-Remarketing Distribution Date or Distribution Date,
Distributions accrued on such Preferred Securities will be payable by wire
transfer within the continental United States in immediately available funds to
the bank account number of such holder specified in such request. The relevant
record dates for the Common Securities shall be the same as the record dates for
the Preferred Securities. Distributions payable on any Securities that are not
punctually paid on any Distribution Date, as a result of the Subordinated Note
Issuer having failed to make a payment under the Subordinated Notes, will cease
to be payable to the Holder on the relevant record date, and such defaulted
Distributions 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.

          (e) The Distribution Rate on the Trust Securities (as well as the
interest rate on the Subordinated Notes) shall be reset in the manner provided
in Section 6.03 of the Agreement and in the Indenture.

          (f) 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 herein) among the Holders of the Securities.

           3.   Remarketing.

         The Preferred Securities shall be remarketed in accordance with the
provisions of Article 6 of the Agreement.

         FROM AND AFTER THE REMARKETING SETTLEMENT DATE ON WHICH REPLACEMENT
SECURITIES ARE ISSUED, THIS CERTIFICATE SHALL REPRESENT ONLY THE RIGHT TO
RECEIVE THE REMARKETING PRICE, AS PROVIDED IN THE TRUST AGREEMENT, AND SHALL NO
LONGER REPRESENT AN OBLIGATION OF OR INTEREST IN THE TRUST.

           4.   Liquidation Distribution Upon Dissolution.

         In the event of any dissolution of the Trust, the Trust shall be
liquidated by the Administrative Trustees as expeditiously as the Administrative
Trustees determine to be possible by distributing pursuant to Section 5, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, to the Holders of the Securities a Like Amount (as defined below) of the
Subordinated Notes, unless such distribution is determined by the Property
Trustee not to be practicable, in which event such Holders will be entitled to
receive out of the assets of the Trust legally available for distribution to
Holders, after satisfaction of liabilities to creditors of the Trust as provided
by applicable law, an amount equal to the aggregate of the


                                      I-4
<PAGE>   92
Liquidation Amount of $1,000 per Security plus accumulated and unpaid
Distributions thereon to the date of payment (such amount being the "LIQUIDATION
DISTRIBUTION").

         "LIKE AMOUNT" means (i) with respect to a redemption of the Securities,
Securities having a Liquidation Amount equal to the principal amount of
Subordinated Notes to be paid in accordance with their terms and (ii) with
respect to a distribution of Subordinated Notes upon the dissolution of the
Trust, Subordinated Notes having a principal amount equal to the Liquidation
Amount of the Securities of the Holder to whom such Subordinated Notes are
distributed.

         If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets on hand legally 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.

           5.   Redemption and Distribution.

          (a) Upon the repayment of the Subordinated Notes in whole or in part,
at maturity or upon acceleration or redemption, the proceeds from such repayment
shall be simultaneously applied by the Property Trustee to redeem a Like Amount
of the Securities at the Mandatory Redemption Price (as defined below). In the
case of an early redemption pursuant to a Special Event, Holders will be given
not less than 30 nor more than 60 days notice of such redemption. Any redemption
of Securities shall be made, and the Mandatory Redemption Price shall be
payable, on the applicable redemption date, and only to the extent that the
Trust has funds legally available for the payment thereof.

          (b) The "MANDATORY REDEMPTION PRICE" shall mean a price equal to 100%
of the Liquidation Amount of the Securities to be redeemed plus accumulated and
unpaid Distributions thereon, if any, to the date of redemption.

          (c) If at any time a Tax Event or Investment Company Event (each as
defined in the Trust Agreement) (a "SPECIAL EVENT") occurs, the Subordinated
Note Issuer shall have the right (subject to the conditions set forth in the
Indenture) at any time, upon not less than 30 nor more than 60 days notice, to
redeem the Subordinated Notes in whole, but not in part, within the 90 days
following the occurrence of such Special Event (the "90 DAY PERIOD"), and,
simultaneous with such redemption, to cause a Like Amount of the Securities to
be redeemed by the Trust at the Mandatory Redemption Price on a Pro Rata basis.

          (d) On and from the date fixed by the Administrative Trustees for any
distribution of Subordinated Notes and liquidation of the Trust: (i) the
Securities will no longer be deemed to be outstanding and (ii) the Depository or
its nominee (or any successor Depository or its nominee), as the Holder of the
Preferred Securities, will


                                      I-5
<PAGE>   93
receive a registered global certificate or certificates representing the
Subordinated Notes to be delivered upon such distribution and any certificates
representing Securities not held by the Depository or its nominee (or any
successor Depository or its nominee) will be deemed to represent beneficial
interests in a Like Amount of Subordinated Notes until such certificates are
presented to the Subordinated Note Issuer or its agent for transfer or reissue.
The Subordinated Notes shall be distributed to the Holders pursuant to Section
2.04 of the Supplemental Indenture.

          (e) The Trust may not redeem fewer than all the outstanding
Securities.

          (f) The notice procedure with respect to redemptions pursuant to a
Special Event or distributions of Subordinated Notes shall be as follows:

                  (i) Notice of any such redemption of, or notice of
         distribution of Subordinated Notes in exchange for, the Securities (a
         "REDEMPTION/DISTRIBUTION NOTICE") will be given by an Administrative
         Trustee on behalf of 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 Subordinated
         Notes. For purposes of the calculation of the date of redemption or
         exchange and the dates on which notices are given pursuant to this
         Section 5(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) Redemption/Distribution Notices shall be sent by the
         Property Trustee on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Depository or its nominee) if the Global Preferred Securities have been
         issued or, if Definitive Preferred Securities have been issued, to the
         Holders thereof, and (B) in respect of the Common Securities, to the
         Holder thereof.

          (g) The payment procedure with respect to all redemptions shall be as
follows:

                  (i) If Securities are to be redeemed, whether or not the Trust
         gives a Redemption/Distribution Notice (which notice will be
         irrevocable), then (A) with respect to Preferred Securities issued in
         book-entry form, by 12:00 noon, New York City time, on the redemption
         date, provided that the


                                      I-6
<PAGE>   94
         Subordinated Note Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Subordinated Notes by 10:00 a.m., New York City time, on the
         maturity date or the date of redemption, as the case requires, the
         Property Trustee will deposit irrevocably with the Depository or its
         nominee (or successor Depository or its nominee) immediately available
         funds sufficient to pay the Mandatory Redemption Price with respect to
         such Preferred Securities and will give the Depository irrevocable
         instructions and authority to pay the Mandatory Redemption Price to the
         relevant Participants, and (B) with respect to Preferred Securities
         issued in certificated form and Common Securities, provided that the
         Subordinated Note Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Subordinated Notes, the Property Trustee will pay the Mandatory
         Redemption Price to the Holders of such Securities by check mailed to
         the address of the relevant Holder appearing on the books and records
         of the Trust on the redemption date; provided, however, that at the
         written request of any Holder of at least $10,000,000 aggregate
         Liquidation Amount of Preferred Securities received by the Property
         Trustee not later than 9:00 a.m. on the redemption date, the Mandatory
         Redemption Price payable to such Holder will be payable by wire
         transfer within the continental United States in immediately available
         funds to the bank account number of such Holder specified in such
         request. If a Redemption/Distribution Notice, if necessary, shall have
         been given and funds deposited as required, if applicable, then
         immediately prior to the close of business on the date of such deposit,
         or on the redemption date, as applicable, Distributions will cease to
         accumulate on the Securities so called for redemption and 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 on such Redemption Price, and such
         Securities shall cease to be outstanding.

                  (ii) Payment of accumulated and unpaid Distributions on the
         Redemption Date of the Securities will be subject to the rights of
         Holders of Securities on the close of business on a regular record date
         in respect of a Distribution Date occurring on or prior to such
         redemption date.

                  (iii) If any date fixed for redemption of Securities is not a
         Business Day, then payment of the Mandatory Redemption Price 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), with the same force and effect as if made on such date fixed
         for redemption. If payment of the Mandatory Redemption Price in respect
         of any Securities is improperly withheld or refused and not paid either
         by the Property Trustee or by the Sponsor as guarantor pursuant to the
         relevant Securities Guarantee, Distributions on such Securities will
         continue to accumulate from the original


                                      I-7
<PAGE>   95
         redemption date to the actual date of payment, in which case the actual
         payment date will be considered the date fixed for redemption for
         purposes of calculating the Mandatory Redemption Price.

          (h) Neither the Administrative Trustees nor the Trust shall be
required to register or cause to be registered the transfer of any Securities
beginning on the opening of business 15 days before the day of mailing of a
notice of redemption.

         (i) Subject to the foregoing, the provisions of the Remarketing
Agreement and applicable law (including, without limitation, United States
Federal securities laws), the Sponsor 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.

           6. Voting Rights - Preferred Securities.

          (a) Except as provided under Sections 6(b) and 8 and as otherwise
required by law or the Agreement, the Holders of the Preferred Securities will
have no voting rights.

          (b) So long as any Subordinated Notes are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding with respect to any remedy available to the
Subordinated Note Trustee, or exercise any trust or power conferred upon the
Subordinated Note Trustee with respect to the Subordinated Notes, (ii) waive any
past default that is waivable under Section 6.04 of the Indenture, (iii)
exercise any right to rescind or annul a declaration of acceleration of the
maturity of the principal of the Subordinated Notes or (iv) consent to any
amendment, modification or termination of the Indenture or the Subordinated
Notes, where such consent shall be required, without, in each case, obtaining
(1) the prior approval of the Holders of a Majority in Liquidation Amount of all
outstanding Preferred Securities; provided, however, that where a consent under
the Indenture would require the consent of each holder of Subordinated Notes
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Preferred Securities and (2) an Opinion
of Counsel delivered to the Trust from independent tax counsel experienced in
such matters to the effect that the Trust will not be classified as an
association taxable as a corporation for United States Federal income tax
purposes on account of such action.

         If an Event of Default under the Agreement has occurred and is
continuing and such event is attributable to the failure of the Subordinated
Note Issuer to pay principal of or premium, if any, or interest on the
Subordinated Notes on the date such principal, premium, if any, or interest is
otherwise payable (or in the case of redemption, on the redemption date), then a
Holder of Preferred Securities may directly institute a proceeding against the
Subordinated Note Issuer for enforcement of payment to such Holder of the
principal of or premium, if any, or interest on a


                                      I-8
<PAGE>   96
Like Amount of Subordinated Notes on or after the respective due date specified
herein or in the Subordinated Notes (a "DIRECT ACTION"). In connection with such
Direct Action, the Common Securities Holder will be subrogated to the rights of
such Holder of Preferred Securities to the extent of any payment made by the
Subordinated Note Issuer to such Holder of Preferred Securities in such Direct
Action. Except as provided in the second preceding sentence, the Holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Subordinated Notes.

         Any 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 Property Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, to be
mailed to each Holder of record of Preferred Securities. Each such notice will
include a statement setting forth (i) the date of such meeting (ii) a
description of any resolution proposed for adoption at such meeting on which
such Holders are entitled to vote and (iii) instructions for the delivery of
proxies.

         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 Subordinated Notes in accordance with the Agreement and the terms
of the Securities.

         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 Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

           7. Voting Rights - Common Securities.

          (a) Except as provided under Sections 7(b) and 8 as otherwise required
by law or the Agreement, the Holders of the Common Securities will have no
voting rights.

          (b) So long as any Subordinated Notes are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding with respect to any remedy available to the
Subordinated Note Trustee, or exercise any trust or power conferred upon the
Subordinated Note Trustee with respect to the Subordinated Notes, (ii) waive any
past default that is waivable under Section 6.04 of the Indenture, (iii)
exercise any right to rescind or annul a declaration of acceleration of the
maturity of the principal of the Subordinated Notes or (iv) consent to any
amendment, modification or termination of the Indenture or the Subordinated
Notes, where such consent shall be required, without, in each case, obtaining
(A) the


                                      I-9
<PAGE>   97
prior approval of the Holders of a Majority in Liquidation Amount of all
outstanding Common Securities; provided, however, that where a consent under the
Indenture would require the consent of each holder of Subordinated Notes
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Common Securities and (B) an Opinion of
Counsel delivered to the Trust from independent tax counsel experienced in such
matters to the effect that the Trust will not be classified as an association
taxable as a corporation for United States Federal income tax purposes on
account of such action.

         If an Event of Default under the Agreement has occurred and is
continuing and such event is attributable to the failure of the Subordinated
Note Issuer to pay principal of or premium, if any, or interest on the
Subordinated Notes on the date such principal, premium, if any, or interest is
otherwise payable (or in the case of redemption, on the redemption date), then a
Holder of Common Securities may institute a Direct Action against the
Subordinated Note Issuer for enforcement of payment to such Holder of the
principal of or premium, if any, or interest on a Like Amount of Subordinated
Notes on or after the respective due date specified in the Subordinated Notes.
Except as provided in the immediately preceding sentence, the Holders of Common
Securities will not be able to immediately exercise directly any other remedy
available to the holders of the Subordinated Notes.

         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 Administrative Trustees will cause a notice of any meeting
at which Holders of Common Securities are entitled to vote 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 and (iii) instructions for
the delivery of proxies.

         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 Subordinated Notes in accordance with the Agreement and these terms of the
Securities.

           8.   Amendments to Agreement.

         In addition to the requirements set out in Section 12.01 of the
Agreement, the Agreement may be amended from time to time by the Sponsor, the
Property Trustee and the Administrative Trustees, with (i) the consent of
Holders representing a Majority in Liquidation Amount of all outstanding
Securities, and (ii) receipt by the Trustees of a reasoned Opinion of Counsel of
independent tax counsel experienced in such matters to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the


                                      I-10
<PAGE>   98
Trust's status as a grantor trust for United States Federal income tax purposes
or the Trust's exemption from status as an Investment Company under the
Investment Company Act, provided that, without the consent of each Holder of
Trust Securities, the Agreement may not be amended to (i) change the amount or
timing of any Distribution on the Trust Securities or otherwise adversely affect
the amount of any Distribution required to be made in respect of the Trust
Securities as of a specified date or (ii) restrict the right of a Holder of
Securities to institute suit for the enforcement of any such payment on or after
such date.

           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 Agreement 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 with the Common Securities and
payment thereon shall be made Pro Rata with the Common Securities, except that,
if an Event of Default under the Agreement occurs and is continuing, no payments
in respect of Distributions on, or payments upon liquidation, redemption or
otherwise with respect to, the Common Securities shall be made until the Holders
of the Preferred Securities shall be paid in full the Distributions, Mandatory
Redemption Price, Liquidation Distribution and other payments to which they are
entitled at such time.

          11.   Acceptance of Securities Guarantees and Indenture.

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


                                      I-11
<PAGE>   99
          12.   No Preemptive Rights.

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

          13.   Miscellaneous.

         These terms constitute a part of the Agreement.

         The Sponsor will provide a copy of the Agreement, the Preferred
Securities Guarantee or the Common Securities Guarantee (as may be appropriate)
and the Indenture (including any supplemental indenture) to a Holder without
charge on written request to the Sponsor at its principal place of business.

                          [FORM OF REVERSE OF SECURITY]

          (a) Distributions with respect to the Liquidation Amount of $1,000 per
Preferred Security (the "LIQUIDATION AMOUNT") will accrue and be payable at a
rate (the "DISTRIBUTION RATE") (such rate being the rate of interest payable on
the Subordinated Notes to be held by the Property Trustee) per annum equal to

                  (i) from and including the date of issuance to but excluding
         the date such Securities are redeemed, LIBOR plus 175 basis points,
         compounded quarterly;

                  (ii) from and including the Remarketing Settlement Date on
         which Replacement Securities are issued to but excluding the date such
         Securities are redeemed, the Winning Bid Rate, compounded quarterly;
         and

                  (iii) notwithstanding clauses (i) and (ii) above, if the
         Securities are not redeemed because the Sponsor fails to pay the
         principal amount of the Subordinated Notes on the date such amount
         becomes due, then, from and including such due date to but excluding
         the date the Securities are redeemed, the Default Rate, compounded
         quarterly, but only to the extent permitted by applicable law.

Distributions in arrears for more than one quarterly period will bear additional
distributions thereon compounded quarterly at the applicable periodic
Distribution Rate specified above (to the extent permitted by applicable law).
Distributions are payable if and to the extent the Subordinated Note Issuer
makes a payment of Additional Interest (as defined in the Indenture) upon the
occurrence of certain events specified in the Indenture. The term
"DISTRIBUTIONS", as used herein, includes any such additional distributions
unless otherwise stated. A Distribution is payable only to the extent that
payments are made in respect of the Subordinated Notes held by the Property
Trustee and to the extent the Property Trustee has funds on hand legally
available therefor.

          (b) Until the Remarketing Settlement Date on which Replacement
Securities are issued, Distributions on this Preferred Security will be
cumulative, will be payable quarterly in arrears on February 12, May 12, August
12 and November 12 of each year, commencing February 12, 1999, and on such
Remarketing Settlement Date (each, a "PRE-REMARKETING DISTRIBUTION DATE"), will
accumulate from and including the most recent date to which Distributions have
been paid or, if no Distributions have been paid, from November 12, 1998, to but
excluding the related Pre-Remarketing Distribution Date, except as otherwise
described below.

<PAGE>   104
         The Distribution Rate in effect for the period from and including
November 12, 1998 to but excluding February 12, 1999 shall be the rate
determined by the Calculation Agent two London Banking Days prior to November
12, 1998 and shall equal LIBOR plus 175 basis points. The Distribution Rate in
effect thereafter, for each quarterly period from and including the immediately
preceding Pre-Remarketing Distribution Date to but excluding the applicable
Pre-Remarketing Distribution Date, shall be determined by the Calculation Agent
two London Banking Days prior to such immediately preceding Pre-Remarketing
Distribution Date and shall equal LIBOR plus 175 basis points. The amount of
Distributions payable for any quarterly period shall be computed on the basis of
a 360-day year of twelve 30-day months. Except as provided in the last sentence
of this paragraph, the amount of Distributions payable for any period shorter
than a full quarterly period for which Distributions are computed will be
computed on the basis of the actual number of days elapsed per 30-day month. If
a Pre-Remarketing Distribution Date is not a Business Day, then such
Pre-Remarketing Distribution Date will be the next succeeding Business Day,
except if such Business Day is in the next succeeding calendar month, such
Pre-Remarketing Distribution Date will be the immediately preceding Business
Day.

         As used herein, "LONDON BANKING DAY" means any day on which dealings in
deposits in U.S. Dollars are transacted in the London interbank market.

          (c) From and including the Remarketing Settlement Date on which
Replacement Securities are issued, Distributions on the Replacement Securities
will be cumulative, will be payable quarterly in arrears on February 12, May 12,
August 12 and November 12 of each year, commencing on the Remarketing Settlement
Date, and on the Mandatory Redemption Date (each, a "DISTRIBUTION DATE"), will
accumulate from the most recent date to which Distributions have been paid or,
if no Distributions have been paid, from and including the Remarketing
Settlement Date, to but excluding the related Distribution Date, except as
otherwise described below. The amount of Distributions payable for any quarterly
period shall be computed on the basis of a 360-day year of twelve 30-day months.
Except as provided in the last sentence of this paragraph, the amount of
Distributions payable for any period shorter than a full quarterly period for
which Distributions are computed will be computed on the basis of the actual
number of days elapsed per 30-day month. If a Distribution Date is not a
Business Day, then such Distribution Date will be the next succeeding Business
Day, except if such Business Day is in the next succeeding calendar month, such
Distribution Date will be the immediately preceding Business Day.

         Subject to other conditions set forth in the Agreement and the
Indenture, the Property Trustee may, at the direction of the Sponsor, at any
time dissolve the Trust and cause the Subordinated Notes to be distributed to
the Holders of the


                                      A1-5

Securities in liquidation of the Trust or, simultaneously with any redemption of
the Subordinated Notes, cause a Like Amount of the Securities to be redeemed by

Agreement.

          (a) Distributions with respect to the Liquidation Amount of $1,000 per

                          [FORM OF REVERSE OF SECURITY]

         Distributions with respect to the Liquidation Amount of $1,000 per
Security (the "LIQUIDATION AMOUNT") will accrue and be payable at a rate (the
"DISTRIBUTION RATE", such rate being the rate of interest payable on the
Subordinated Notes to be held by the Property Trustee) per annum equal to

                  (i) from and including the date of issuance to but excluding
         the date such Securities are redeemed, the Winning Bid Rate, compounded
         quarterly; and

                  (ii) notwithstanding clause (i) above, if the Securities are
         not redeemed because the Sponsor fails to pay the principal amount of
         the Subordinated Notes on the date such amount becomes due, then from
         and including such due date to but excluding the date the Securities
         are redeemed, the Default Rate, compounded quarterly but only to the
         extent permitted by applicable law.

Distributions in arrears for more than one quarterly period will bear additional
distributions thereon compounded quarterly at the applicable periodic
Distribution Rate specified above (to the extent permitted by applicable law).
Distributors are payable if and to the extent the Subordinated Note Issuer makes
a payment of Additional Interest (as defined in the Indenture) upon the
occurrence of certain events specified in the Indenture. The term
"DISTRIBUTIONS", as used herein, includes any such additional distributions
unless otherwise stated. A Distribution is payable only to the extent that
payments are made in respect of the Subordinated Notes held by the Property
Trustee and to the extent the Property Trustee has funds on hand legally
available therefor.

         From and including the date of issuance, Distributions on the
Replacement Securities will be cumulative, will be payable quarterly in arrears
on February 12, May 12, August 12 and November 12 of each year, commencing on
the Remarketing Settlement Date, and on the Mandatory Redemption Date (each, a
"DISTRIBUTION DATE"), will accumulate from the most recent date to which
Distributions have been paid or, if no Distributions have been paid, from and
including the date of issuance, to but excluding the related Distribution Date,
except as otherwise described below. The amount of Distributions payable for any
quarterly period shall be computed on the basis of a 360-day year of twelve
30-day months. Except as provided in the last sentence of this paragraph, the
amount of Distributions payable for any period shorter than a full quarterly
period for which Distributions are computed will be computed on the basis of the
actual number of days elapsed per 30-day month. If a Distribution Date is not a
Business Day, then such Distribution Date will be the next succeeding Business
Day, except if such Business Day is in the next succeeding calendar month, such
Distribution Date will be the immediately preceding Business Day.

         Subject to certain conditions set forth in the Agreement and the
Indenture, the Property Trustee may, at the direction of the Sponsor, at any
time dissolve the Trust and cause the Subordinated Notes to be distributed to
the Holders of the Securities in liquidation of the Trust or, simultaneously
with any redemption of the Subordinated Notes, cause a Like Amount of the
Securities to be redeemed by the Trust.

         This Preferred Security shall be redeemable as provided in the
Agreement.

         the expected results of this Agreement. Each other party is not acting
         as a fiduciary for or an adviser to it in respect of this Agreement.

         Trust and the Company, as the case may be, and authenticated, issued
         and


                                       7

         delivered in the manner provided for in the Trust Agreement and the
         Indenture, respectively, and delivered against payment of the purchase
         price therefor as provided in the Purchase Agreement, and constitute
         legally binding obligations of the Trust or the Company, as the case
         may be, entitled to the benefits of the Trust Agreement and Indenture.

                  (ii) No Event of Default. No Event of Default under the Trust
         Agreement and no Event of Default under the Indenture or Cross Default
         has occurred and is continuing and no such event or circumstance would

         under this Agreement.

                  (iii) Compliance with Exchange Act Requirements. The Company
         has made all the filings with the Commission that it is required to
         make under the Exchange Act and the Exchange Act Regulations, each such
         filing complies in all material respects with the requirements of the
         Exchange Act and Exchange Act Regulations.

                  (iv) No Material Misstatements. The Company's Annual Report on
         Form 10-K for the fiscal year ended December 31, 1997, its Quarterly
         Reports on Form 10-Q for the periods ended March 31, 1998 and June 30,

         1998 and October 15, 1998 (collectively, the "1934 ACT REPORTS"), as
         supplemented by material press releases, at the time they were filed
         did not, and, giving effect as of the date hereof to the transactions
         contemplated by the Transaction Documents do not, contain any untrue
         statement of a material fact or omit to state a material fact necessary
         in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.

                  (v) No Material Adverse Change. Since the respective dates as
         of which information is given in, except as otherwise stated therein,
         there has been no Material Adverse Change.

                  (vi) Not an Investment Company. Neither the Company nor the
         Trust is an "investment company" or an entity "controlled" by an
         "investment company" as such terms are defined in the Investment
         Company Act.

         SECTION 3.  Covenants.  (a) The Company hereby covenants with the
Remarketing Agent as follows:


                                       8
<PAGE>   11
                  (i) Maintain Authorizations. The Company shall use all
         reasonable efforts to maintain in full force and effect all consents of
         any governmental or other authority that are required to be obtained by
         it with respect to this Agreement and shall use all reasonable efforts
         to obtain any that may become necessary in the future.

                  (ii) Comply with Laws. The Company shall comply in all
         material respects with all applicable laws and orders to which it may
         be subject if failure so to comply would materially impair its ability
         to perform its obligations under this Agreement.

                  (iii) Furnish Documentation. The Company will furnish to the
         Remarketing Agent: (i) unless available to the Remarketing Agent on
         EDGAR or the Company's website, each Exchange Act Document filed after
         the date hereof and (ii) in connection with the remarketing of the
         Preferred Securities or Subordinated Notes, as the case may be, such
         other information as the Remarketing Agent may reasonably request from
         time to time. Notwithstanding the foregoing sentence, the Company
         agrees to provide the Remarketing Agent with as many copies of the
         foregoing written materials and other Company-approved information as
         the Remarketing Agent may reasonably request for use in connection with
         the remarketing of the Preferred Securities or Subordinated Notes, as
         the case may be, and consents to the use thereof for such purpose.

                  (iv) Notification. If, at any time prior to the Remarketing
         Settlement Date, any event or condition known to the Company relating
         to or affecting the Company, any Material Subsidiary thereof or the
         Preferred Securities or Subordinated Notes shall occur which could
         reasonably be expected to cause any of the reports, documents,
         materials or information referred to in Section 3(a)(iii) or any
         document incorporated therein by reference to contain an untrue
         statement of a material fact or omit to state a material fact, the
         Company shall promptly notify the Remarketing Agent in writing of the
         then-known circumstances and details of such event or condition.

                  (v) File Exchange Act Documents. At all times prior to the
         Remarketing Settlement Date, the Company will file all documents
         required to be filed with the Commission pursuant to the Exchange Act
         within the time periods required by the Exchange Act and the Exchange
         Act Regulations.

                  (vi) Comply with Securities Laws. The Company will comply with
         the Securities Act and the rules and regulations of the Commission


                                       9
<PAGE>   12
         thereunder, the Exchange Act and the Exchange Act Regulations so as to
         permit the completion of the remarketing of the Preferred Securities or
         Subordinated Notes, as the case may be, as contemplated in this
         Agreement.

                  (vii) No Purchase of Securities. The Company agrees that
         neither it nor any of its subsidiaries or Affiliates shall purchase or
         otherwise acquire, or enter into any agreement to purchase or otherwise
         acquire, any of the Preferred Securities or Subordinated Notes prior to
         the remarketing thereof by the Remarketing Agent, other than pursuant
         to the Trust Agreement or the Indenture.

                  (viii) Notification of Rating Agency Action. The Company will
         provide prompt notice by telephone, confirmed in writing (which may
         include facsimile or other electronic transmission), to the Remarketing
         Agent of any notification or announcement by a "nationally recognized
         statistical rating organization" (as defined by the Commission for
         purposes of Rule 436(g)(2) under the Securities Act) with regard to a
         downgrade to below investment grade or withdrawal of the rating of any
         security of the Company or the placement on what is currently called a
         "watch list"or a "credit watch" with negative implications of any
         security of the Company.

                  (ix) Restriction on Debt Issuance. During the three Business
         Day period ending on the Remarketing Settlement Date, the Company will
         not, without the consent of the Remarketing Agent, offer, sell or
         contract to sell, or otherwise dispose of, directly or indirectly, or
         announce the offering of, any debt securities with a maturity of more
         than one year.

                  (x) Best Efforts. The Company shall use its best efforts to
         assist the Remarketing Agent in remarketing the Preferred Securities or
         the Subordinated Notes, as the case may be, in the manner contemplated
         in this Agreement.

          (b) The Remarketing Agent hereby covenants with the Company as
follows:

                  (i) Maintain Authorizations. The Remarketing Agent will use
         all of its reasonable efforts to maintain in full force and effect all
         consents of any governmental or other authority that are required to be
         obtained by it with respect to this Agreement and shall use all
         reasonable efforts to obtain any that may become necessary in the
         future.


                                       10
<PAGE>   13
                  (ii) Comply with Laws. The Remarketing Agent shall comply in
         all material respects with all applicable laws and orders which it may
         be subject if failure so to comply would materially impair its ability
         to perform its obligations under this Agreement.

         SECTION 4. Appointment and Obligations of Remarketing Agent and
Calculation Agent; Secondary Purchaser. (a) The Company and the Trust hereby
appoint NMS as Remarketing Agent and as Calculation Agent under the Trust
Agreement and the Indenture and NMS hereby accepts such appointments (i) to
determine, pursuant to the process described in Section 5(b), the Reset Rate
that, when applied to the Preferred Securities (and, thus, the Subordinated
Notes), shall result in the resale of all outstanding Preferred Securities (or,
following any distribution of Subordinated Notes, all such Subordinated Notes),
at a sales price equal to 100.5% of the aggregate stated liquidation amount of
such Preferred Securities, or 100.5% of the aggregate principal amount of such
Subordinated Notes (provided that the Reset Rate shall in no event exceed the
rate permitted by applicable law), (ii) as the Remarketing Agent to conduct a
private auction of all outstanding Preferred Securities, or, following the
distribution of Subordinated Notes to holders of the Preferred Securities upon
termination of the Trust, all such Subordinated Notes, as the case may be and
(iii) to enter into a Secondary Purchase Agreement.

          (b) Pursuant to the Secondary Purchase Agreement, the Secondary
Purchaser, either as the sole purchaser or as the representative of a syndicate
of purchasers designated by the Remarketing Agent, shall agree, subject to the
terms and conditions set forth therein, that the Secondary Purchaser and any
such other purchasers shall purchase such Preferred Securities or Subordinated
Notes, as the case may be, from the holders thereof at a price equal to the
Remarketing Price.

         SECTION 5.  Determination of Reset Date; Remarketing Procedures.  (a)
Subject to Sections 7 and 10, the Reset Date shall be September 28, 1999 (the
"EXPECTED RESET DATE"); provided that

                  (i) the Company may, by notice to the Remarketing Agent,
         direct that the Reset Date be delayed if the Company believes it will
         be unable to meet the conditions to Remarketing in the absence of such
         a delay; and

                  (ii) the Remarketing Agent may, by notice to the Company,
         direct that the Reset Date be delayed if the Remarketing Agent believes
         that a Remarketing will not be successful in the absence of such a
         delay;


                                       11
<PAGE>   14
and, in either such event, the Company and the Remarketing Agent will use their
best efforts to establish a delayed Reset Date that is within five Business Days
after the Expected Reset Date, but in no event later than the Final Reset Date;
and provided, further, that no Reset Date may be established if any Cross
Default (as defined in the Credit Agreement) has occurred, except in connection
with a Remarketing following a Cured Default Trigger Event pursuant to Section
10(ii). If the Company and the Remarketing Agent have not agreed, on or prior to
the sixth Business Day preceding the Final Reset Date, to a Reset Date that is
not later than the Final Reset Date, no Remarketing shall occur, the Preferred
Securities (if then outstanding) shall be redeemed at the Mandatory Redemption
Price and the Company shall repay the Subordinated Notes in accordance with
their terms on the Mandatory Redemption Date.

          (b) The Company shall, by notice to the Remarketing Agent no later
than five Business Days prior to the Reset Date, select and specify at least
three but not more than five Reference Corporate Dealers. By 3:00 p.m., New York
City time, on the Reset Date, the Remarketing Agent shall request Bids from such
Reference Corporate Dealers. The Remarketing Agent shall determine the lowest
Bid Rate (the "WINNING BID RATE") from among the Bids obtained on the Reset
Date. By approximately 4:30 p.m., New York City time, on the Reset Date, the
Remarketing Agent shall notify the Company, the Underwriter, the Indenture
Trustee and the Property Trustee of the Winning Bid Rate. If on a Reset Date,
Bids are not submitted by at least two Reference Corporate Dealers, or if the
lowest Bid submitted would result in a Winning Bid Rate in excess of the rate
permitted by applicable law, such Remarketing shall be deemed to be a Failed
Remarketing on the corresponding Remarketing Settlement Date. The Winning Bid
Rate determined by the Remarketing Agent, absent manifest error, shall be
binding and conclusive upon the Holders of the Trust Securities, the holders of
the Subordinated Notes, the Company and the Trust.

          (c) On the Reset Date, the Remarketing Agent shall designate as the
Secondary Purchaser (the "SECONDARY PURCHASER") the Reference Corporate Dealer
providing the Bid containing the Winning Bid Rate. If the Winning Bid Rate is
specified in the Bids submitted by two or more Reference Corporate Dealers, the
Remarketing Agent shall, in its sole discretion, designate one of such
Reference Corporate Dealers as the Secondary Purchaser.

          (d) On the Reset Date, the Secondary Purchaser shall enter into a
Secondary Purchase Agreement for the purchase by such Secondary Purchaser at the
Remarketing Price of the aggregate Liquidation Amount of Preferred Securities,
with a Distribution Rate equal to the Winning Bid Rate (or, if Subordinated
Notes shall have been distributed to Holders of the Trust Securities, the
aggregate principal amount of Subordinated Notes with an interest rate equal


                                       12
<PAGE>   15
to the Winning Bid Rate) and with a Mandatory Redemption Date (or, in the case
of Subordinated Notes, a maturity date) on the Maturity Extension Date.

          (e) If a Remarketing shall have occurred pursuant to this Section 5
but settlement of the purchase and sale of the Preferred Securities or
Subordinated Notes, as the case may be, does not occur on the corresponding
Remarketing Settlement Date, then, unless the provisions of Section 7 with
respect to a Renewed Remarketing shall apply, a Failed Remarketing shall be
deemed to occur on such Remarketing Settlement Date.

          (f) At the time and in the manner specified in the Secondary Purchase
Agreement, the Secondary Purchaser shall pay to the Remarketing Agent on behalf
of the holders of the Preferred Securities or Subordinated Notes, as the case
may be, on the Remarketing Settlement Date, an amount of cash equal to the
Remarketing Price.

          (g) Unless otherwise agreed among the Remarketing Agent, the paying
agent (under the Trust Agreement or Indenture as applicable) and any Former
Holder, the Remarketing Agent shall promptly pay the Remarketing Price, less the
Remarketing Fee, to the paying agent, acting solely as agent for the Former
Holders, and the paying agent shall pay such amount to the Former Holders on the
Remarketing Settlement Date in the manner specified in the Trust Agreement or
the Indenture, as the case may be. Any amounts held by the Paying Agent for
payment to the Former Holders shall not be property of the Trust.

          (h) The obligation of the Remarketing Agent to make payment to the
Former Holders in connection with the Remarketing shall be limited to the extent
that the Secondary Purchaser has delivered the Remarketing Price therefor to the
Remarketing Agent.

          (i) Any outstanding Preferred Securities (or, if Subordinated Notes
shall have been distributed to holders of the Trust Securities, Subordinated
Notes) purchased on the Remarketing Settlement Date shall be deemed to be
transferred to the Secondary Purchaser and shall be replaced in the manner
provided in Section 5(j). On and after the Remarketing Settlement Date (except
in the event of a Failed Remarketing), the Trust (or the Company, in the case of
the Subordinated Notes) shall make no further payments to, and the Trust (or the
Company, in the case of the Subordinated Notes) shall have no further
obligations under the Trust Agreement (or the Indenture in the case of the
Subordinated Notes) in respect of, the Holders of such replaced securities (the
"FORMER HOLDERS"), the Trust (or the Company, in the case of the Subordinated
Notes) shall only be obligated to make payments to the Holders of Replacement
Securities, and the Preferred Securities (or Subordinated Notes) of the Former


                                       13
<PAGE>   16
Holders shall no longer represent an obligation of, or interest in, the Trust
(or the Company, in the case of the Subordinated Notes) but shall only represent
a right to receive the proceeds of the Remarketing from the Paying Agent under
the Trust Agreement or the Indenture, as the case may be.

          (j) The Company shall cause replacement certificates evidencing the
remarketed Preferred Securities (or Subordinated Notes) to be executed by an
Administrative Trustee (or, in the case of Subordinated Notes, an authorized
signatory) on behalf of the Trust (or, in the case of Subordinated Notes, on
behalf of the Company) and authenticated by the Property Trustee or the
Indenture Trustee in accordance with the provisions of Section 5 (the
"REPLACEMENT SECURITIES"). The Replacement Securities shall be delivered to the
purchaser or purchasers of the remarketed Preferred Securities (or Subordinated
Notes) in accordance with the terms of the Secondary Purchase Agreement.

         SECTION 6. Reset of Distribution Rate, Mandatory Redemption Date,
Interest Rate and Maturity Date. Unless a Failed Remarketing or Renewed
Remarketing shall have occurred, from and including the Reset Settlement Date,
the Distribution Rate on the Trust Securities and the interest rate on the
Subordinated Notes shall be the Winning Bid Rate and the mandatory redemption
date of the Trust Securities and the maturity date of the Subordinated Notes
shall be the Maturity Extension Date.

         SECTION 7. Renewed Remarketing. If a Remarketing has occurred pursuant
to Section 5 that would be a Failed Remarketing pursuant to Section 5(e),
because the purchase and sale of the Preferred Securities (or, if Subordinated
Notes shall have been distributed to Holders of the Trust Securities,
Subordinated Notes) does not take place on the corresponding Remarketing
Settlement Date, and the reason for such failure shall, in the good faith
determination of the Remarketing Agent (made after consultation with the
Company), result from facts or circumstances that are not due to the action or
inaction of the Company, then the provisions of Section 5 and this Section 7
shall apply to any remarketing (each, a "RENEWED REMARKETING") of the Preferred
Securities (or, if Subordinated Notes shall have been distributed to Holders of
the Trust Securities, Subordinated Notes), except that the Expected Reset Date
shall be the sixth Business Day following such corresponding Remarketing
Settlement Date. The provisions of this Section 7 shall apply successively to
each Renewed Remarketing, provided that no Renewed Remarketing shall occur after
the Final Reset Date.

         SECTION 8. Remarketing Fee. With respect to the Remarketing, the
Remarketing Agent shall retain as a remarketing fee (the "REMARKETING FEE") an
amount equal to 25 basis points (.25%) of the aggregate stated liquidation 
amount


                                       14
<PAGE>   17
(the "LIQUIDATION AMOUNT") of the remarketed Preferred Securities or 25 basis
points (.25%) of the aggregate principal amount of the Subordinated Notes, as
the case may be, from the purchase price received in connection with such
Remarketing.

         SECTION 9. Failed Remarketing; Mandatory Redemption. The Remarketing
Agent shall give notice of any Failed Remarketing on the date such Failed
Remarketing occurs, or is deemed to occur, by 4:00 p.m., New York City time, on
the date of such Failed Remarketing, to the Subordinated Note Issuer, the
Property Trustee, the Indenture Trustee, the Underwriter and the Paying Agent
under the Indenture. In the case of any Failed Remarketing, the Company shall
redeem the Subordinated Notes in whole, but not in part, on the third Business
Day following the date such Failed Remarketing occurs or is deemed to occur, and
the proceeds from such repayment shall be simultaneously applied by the Property
Trustee to redeem a like amount of any outstanding Trust Securities at the
Mandatory Redemption Price on a pro rata basis in the manner provided in Section
5 of Annex I to the Trust Agreement.

         SECTION 10. Early Remarketing. If any of the following events (each, a
"TRIGGER EVENT") shall have occurred:

         (a) the Closing Price of the Common Stock on any Trading Day, as
determined by the Remarketing Agent, is less than the Trigger Price (a "STOCK
PRICE TRIGGER EVENT");

         (b) a Cross Default shall have occurred but such Cross Default shall
have ceased to be continuing (a "CURED DEFAULT TRIGGER EVENT"); or

         (c) the Company shall have made a written request to the Underwriter to
enter into a firm commitment underwriting of the Common Stock, and the Company
and the Underwriter shall have substantially agreed to the terms of such
underwriting in the manner described in Section 2 of the Forward Underwriting
Agreement or shall have given notice to accelerate the Commencement Date in the
manner described in Section 7(c) of the Forward Underwriting Agreement (an
"UNDERWRITING TRIGGER EVENT");

then a Remarketing shall occur pursuant to Section 5 and, if applicable, Section
7, except that:

                  (i) the Expected Reset Date shall be the sixth Business Day
         following the date such Trigger Event first occurs;


                                       15
<PAGE>   18
                  (ii) in the case of a Stock Price Trigger Event or a Cured
         Default Trigger Event, the Final Reset Date shall be the 15th day
         following the date such Trigger Event occurs, or the 20th day in the
         case of a Renewed Remarketing to which the provisions of Section 7
         apply, but in no event later than the third scheduled Trading Day prior
         to November 10, 1999;

                  (iii) in the case of an Underwriting Trigger Event, the Final
         Reset Date shall be the 45th day following the date such Trigger Event
         occurs, but in no event later than the third scheduled Trading Day
         prior to November 10, 1999; and

                  (iv) notwithstanding the provisions of clauses (A), (B) and
         (C) above, if a Reset Date has already been established or a
         Remarketing has already taken place at the time such Trigger Event
         occurs, the Remarketing shall occur on such established Reset Date or
         settled on the corresponding Remarketing Settlement Date.

         SECTION 11. Adjustments to Trigger Price. The "TRIGGER PRICE" shall
initially be $22 11/16 (twenty-two and eleven-sixteenths). Following the
determination by the Remarketing Agent in its reasonable discretion that a
Potential Adjustment Event has occurred, the Remarketing Agent shall determine
(after consultation with the Company) whether such Potential Adjustment Event
has a diluting or concentrative effect on the theoretical value of the Common
Stock and, if so, shall make the corresponding adjustment(s), if any, to the
Trigger Price. The Company shall promptly notify the Remarketing Agent of any
Potential Adjustment Event. The Remarketing Agent may, but need not, determine
the appropriate adjustment(s) by reference to the adjustment(s) in respect of
such Potential Adjustment Event made by an options exchange to options on the
Common Stock traded on that options exchange. In the event of any merger,
consolidation or reorganization of the Company, the Remarketing Agent shall
determine the appropriate Trigger Price as a result of such event.

         SECTION 12.  Replacement and Resignation of Remarketing Agent.  (a) The
Company shall not have the right to replace NMS as the Remarketing Agent,
except in the case of bad faith, gross negligence or willful misconduct by NMS.

          (b) NMS may resign at any time for good reason (after consultation
with the Company) and, subject to the following sentence, shall be discharged
from its duties and obligations hereunder or as Calculation Agent under the
Trust Agreement and the Indenture by giving no less than 10 days notice. Any
such resignation shall become effective upon the Company's appointment of a
successor to perform the services that would otherwise be performed hereunder by
the Remarketing Agent or the Calculation Agent under the Trust Agreement and


                                       16
<PAGE>   19
the Indenture, as the case may be, and the agreement of any such successor so to
serve. Upon receiving notice from the Remarketing Agent that it wishes to resign
hereunder or as Calculation Agent under the Trust Agreement and the Indenture
stating the reasons for such resignation, the Company shall appoint such a
successor and enter into a new remarketing agreement with it as soon as
reasonably practicable.

         SECTION 13. Dealing in the Securities. NMS, when acting as Remarketing
Agent hereunder or under the Secondary Purchase Agreement or when acting in its
individual or any other capacity, may, to the extent permitted by law, buy,
sell, hold or deal in any of the Preferred Securities or Subordinated Notes, as
the case may be. With respect to any Preferred Securities or Subordinated Notes,
as the case may be, owned by it, the Remarketing Agent may exercise any vote or
join in any action with like effect as if it did not act in any capacity
hereunder. NMS, in its individual capacity, either as principal or agent, may
also engage in or have an interest in any financial or other transaction with
the Company as freely as if it did not act in any capacity hereunder.

         SECTION 14. Offering Memorandum. Promptly following the date hereof,
the Company shall furnish an offering memorandum (the "OFFERING MEMORANDUM") to
the Remarketing Agent, in form and substance reasonably satisfactory to the
Remarketing Agent, to be used in the remarketing by the Secondary Purchaser or
purchasers under the Secondary Purchase Agreement, and shall pay all expenses
relating thereto.

         SECTION 15. Conditions to the Remarketing Agent's Obligations. (a) The

under the laws of each other jurisdiction where its ownership, lease, licensing

          (e) Valid and Binding Obligations. The Subordinated Notes have been
duly authorized, executed, authenticated and issued and delivered as provided in
the Indenture against payment of the purchase price therefor as provided in the
Indenture, and are validly issued and outstanding, and constitute valid and

Indenture and enforceable against the Company in accordance with their terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other laws of general application relating to or
affecting the enforcement of creditors' rights or by general equitable
principles.

          (f) Non-Contravention of Existing Instruments. Neither the Company nor
any of its Material Subsidiaries is in default or, with the giving of notice or

consummation by the Company of the transactions contemplated hereby, except such

securities or blue sky laws of the various States in connection with the
purchase of the Preferred Securities by the Secondary Purchaser or where the
failure to obtain such consent, approval, authorization, order, registration,
qualification, or make such filing will not adversely affect such authorization,
execution or delivery of this Agreement, the compliance with the terms hereof or
the consummation by the Company of the transactions contemplated hereby.

          (h) Compliance with Exchange Act Requirements. The Company has made
all the filings with the Commission that it is required to make under the

charter document or supplement thereto, respectively, there has been no dividend
or distribution of any kind declared, paid or made by the Company on any class
of its capital stock.

          (n) Capitalization. The authorized, issued and outstanding capital
stock of the Company is as set forth or incorporated by reference in the
Offering Memorandum under the caption ["CAPITALIZATION"] (other than for
subsequent issuances, if any, pursuant to employee benefit and compensation
plans described in the Offering Memorandum or any Incorporated Document or upon
exercise of outstanding options or warrants described in the Offering Memorandum
or any Incorporated Document). Such shares of capital stock have been duly
authorized and validly issued by the Company and are fully paid and
non-assessable and have been issued in compliance with federal and state
securities laws. The capital stock conforms in all material respects to the
description thereof contained in the Offering Memorandum. There are no
authorized or outstanding options, warrants, preemptive rights, rights of first
refusal or other rights to purchase, or equity or debt securities convertible
into or exchangeable or exercisable for, any capital stock of the Company or any
of its subsidiaries other than those accurately described or incorporated by
reference in the Offering Memorandum.

          (o) No Material Actions or Proceedings. There are no actions, suits,
proceedings, inquiries or investigations before or brought by any legal or
governmental agency or body now pending or, to the knowledge of the Company,
threatened, against or affecting the Company or any of its Material Subsidiaries
that are not disclosed in the Offering Memorandum or in any Incorporated
Document. The aggregate of all pending legal or governmental proceedings to
which the Company or any of its Material Subsidiaries is a party or of which any
of their respective assets, properties or operations is the subject that are not
described in the Offering Memorandum or any Incorporated Documents, including
ordinary routine litigation incidental to the business, could not reasonably be
expected to result in a Material Adverse Change.

          (p)   Intellectual Property Rights. Except as otherwise disclosed or
incorporated by reference in the Offering Memorandum, the Company and each


                                      A-9
<PAGE>   33
Material Subsidiary owns, leases, licenses or otherwise possesses adequate
trademarks, service marks, trade names, patents, patent rights, copyrights,
licenses, inventions, approvals, and other intellectual property rights
(collectively, "INTELLECTUAL PROPERTY") necessary to conduct its business as now
conducted. Neither the Company nor any of its Material Subsidiaries has received
any written notice of any infringement of or conflict with, asserted rights of
others with respect to any Intellectual Property which infringement or conflict,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Change.

          (q) Possession of Licenses and Permits. Each of the Company and its
Material Subsidiaries possesses such permits, licenses, approvals, consents and
other authorizations (collectively, "GOVERNMENTAL LICENSES") issued by the
appropriate federal, state, local or foreign regulatory agencies or bodies
necessary to conduct the business now operated by it. The Company and its
Material Subsidiaries are in compliance with the terms and conditions of all
such Governmental Licenses, except where the failure to so comply could not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change. All of the Governmental Licenses are valid and in full force and
effect, except where the invalidity of such Governmental Licenses or the failure
of such Governmental Licenses to be in full force and effect could not
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change. Neither the Company nor any of its Material Subsidiaries has
received any written notice of proceedings relating to the revocation or
modification of any such Governmental Licenses which, individually or in the
aggregate (if the subject of an unfavorable decision, ruling or finding), would
result in a Material Adverse Change.

          (r) Company Not "Investment Company". The Company is not an
"investment company" within the meaning of the Investment Company Act and the
rules and regulations of the Commission thereunder.

          (s) Related Party Transactions. There are no business relationships or
related party transactions involving the Company or any subsidiary or any other
person required to be described in the Offering Memorandum or in any
Incorporated Document that have not been described as required.

          (t)   Environmental Laws.

                  (i) Except as would not have or be reasonably expected to
         result in a Material Adverse Change or as is otherwise described in the
         Exchange Act Reports:

                  all operations at the Real Properties are in compliance with
                  all applicable Environmental Laws, and there is no violation
                  of any Environmental Law with respect to the Real Properties
                  or the businesses operated by the Company or any of its
                  Material Subsidiaries (the "BUSINESSES"), and there are no
                  conditions relating to the Businesses or Real Properties that

                  any applicable Environmental Laws.

                       (B) Neither the Company nor any of its Material
                  Subsidiaries has received any written notice of, or inquiry
                  from any Governmental Authority regarding, any violation,
                  alleged violation, non-compliance, liability or potential
                  liability regarding Hazardous Materials (as defined herein) or
                  compliance with Environmental Laws (as defined herein) with
                  regard to any of the Real Properties or the Businesses, nor
                  does the Company or any of its Material Subsidiaries have
                  knowledge or reason to believe that any such notice is being
                  threatened.

                       (C) Hazardous Materials have not been transported or
                  disposed of from the Real Properties, or generated, treated,
                  stored or disposed of at, on or under any of the Real
                  Properties or any other location, in each case by, or on
                  behalf or with the permission of, the Company or any of its
                  Material Subsidiaries.

                       (D) No judicial proceeding or governmental or
                  administrative action is pending or, to the knowledge of the
                  Company, threatened, under any Environmental Law to which the
                  Company or any of its Material Subsidiaries is or, to the best
                  knowledge of the Company, will be named as a party, nor are
                  there any consent decrees or other decrees, consent orders,
                  administrative orders or other orders, or other administrative
                  or judicial requirements outstanding under any Environmental
                  Law with respect to the Company or any of its Material
                  Subsidiaries, the Real Properties or the Businesses.

                       (E) There has been no release or, to the best knowledge
                  of the Company, threat of release of Hazardous Materials at or
                  from the Real Properties, or arising from or related to the
                  operations (including, without limitation, disposal) of the
                  Company or any of its Material Subsidiaries in connection with
                  the Real Properties or


                                      A-11
<PAGE>   35
                  otherwise in connection with the Businesses, in violation of,
                  or in amounts or in a manner that could give rise to liability
                  under, Environmental Laws.

                       (F) None of the Real Properties contains, or has
                  previously contained, any Hazardous Materials at, on or under
                  the Real Properties in amounts or concentrations that, if
                  released, constitute or constituted a violation of, or would
                  give rise to liability under, Environmental Laws.

                       (G) Neither the Company, nor any of its Material
                  Subsidiaries, has assumed any liability of any person (other
                  than the Company or one of its Material Subsidiaries) under
                  any Environmental Law.

                  (ii) The Company has adopted procedures that are designed to
         (A) ensure that for the Company and each of its Material Subsidiaries,
         each of their respective operations and each of the properties owned or
         leased by the Company and each of its Material Subsidiaries remains in
         compliance with applicable Environmental Laws, to the extent that the
         failure to comply with such Environmental Laws would result in or would
         be reasonably expected to result in a Material Adverse Change, and (B)
         manage, to the same extent as and in accordance with the practices of
         companies engaged in the same or a similar business, any liabilities or
         potential liabilities that the Company and each of its Material
         Subsidiaries, any of its respective operations and each of the
         properties owned or leased by the Company and each of its Material
         Subsidiaries may have under applicable Environmental Laws.

Agreement or the Indenture under the Trust Indenture Act of 1939, as amended

otherwise negotiated in respect of, any security (as defined in the Securities
Act) which is or


                                      A-12
<PAGE>   36
will be integrated with the sale of the Preferred Securities in a manner that
would require the registration under the Securities Act of the Preferred
Securities.

          (w) No Solicitation. No form of general solicitation or general
advertising was used by the Company, the Trust or, to the best of its knowledge,
any other person acting on behalf of the Company or the Trust in respect of the
Preferred Securities or in connection with the remarketing and sale of the
Preferred Securities (as those terms are used in Regulation D under the
Securities Act), or in any manner involving a public offering within the meaning
of Section 4(2) of the Securities Act. Neither the Company, the Trust nor any
person acting on behalf of the Company or the Trust has, either directly or
indirectly, sold or offered for sale to any person any of the Preferred
Securities or any other similar security of the Company or the Trust except for
the Secondary Purchaser, so as thereby to bring the issuance or sale of any of
the Securities within the provisions of Section 5 of the Securities Act or any
Blue Sky law of any state or the provincial securities laws of Canada.

         SECTION 4. Representations and Warranties and Agreements of the Company

warrant and agree that:

          (a) The Trust has been duly created and is validly existing in good
standing as a statutory business trust organized under the Business Trust Act of
the State of Delaware (chapter 38, Title 12, of the Delaware Code, 12 Del. C.
Sec. 3801 et seq.) (the "BUSINESS TRUST ACT"), is a "grantor trust" or
pass-through entity and not an association or publicly traded partnership
subject to taxation as a corporation for Federal income tax purposes under
existing law, has the business trust power and authority to own property,
conduct its business and enter into and perform the obligations under the
Transaction Agreements and is not required to be authorized to do business in
any other jurisdiction. All filings required under the laws of the State of
Delaware with respect to the creation and valid existence of the Trust as a
business trust have been made.

          (b) The Trust has conducted and will conduct no business other than
the transactions contemplated by this Agreement, the Remarketing Agreement and
the Trust Agreement; the Trust is not a party to or bound by any agreement or
instrument other than this Agreement, the Remarketing Agreement and the Trust
Agreement; the Trust has no liabilities or obligations other than those arising

Agreement, the Subscription Agreement, the Subordinated Note Purchase Agreement
and such Trust Agreement; and the Trust is not a party to or subject to any
action, suit or proceeding of any nature.

<PAGE>   37
          (c) The Trust Agreement has been duly authorized, executed and
delivered by the Company, as Sponsor, and the Trustees, and assuming due
authorization, execution and delivery of the Trust Agreement by the Delaware
Trustee (as defined in the Trust Agreement), constitutes a valid and binding
obligation of the Trust, enforceable against the Trust in accordance with its
terms, subject to the effects of bankruptcy, insolvency, reorganization,
moratorium and other laws of general application relating to or affecting the
enforcement of creditors' rights or by general equitable principles.

          (d) The Preferred Securities have been duly authorized by, and
executed and delivered in accordance with the Trust Agreement and represent
validly issued, fully paid and non-assessable undivided beneficial interests in
the assets of the Trust. Holders of the Preferred Securities are entitled to the
same limitation of liability extended to stockholders of private corporations
for profit under the General Corporation Law of the State of Delaware. The
Common Securities have been duly authorized by, and executed and delivered in
accordance with, the Trust Agreement and represent validly issued undivided
beneficial interests in the assets of the Trust. The remarketing of Preferred
Securities(3) will not be subject to any preemptive or similar rights.

          (e) Each of this Agreement and the Remarketing Agreement has been duly
authorized, executed and delivered by, and is a valid and binding obligation of,
the Trust, enforceable against the Trust in accordance with its terms, subject
to the effects of bankruptcy, insolvency, reorganization, moratorium and other
laws of general application relating to or affecting the enforcement of
creditors' rights or by general equitable principles.

          (f) The execution and delivery by the Trust and the performance by the
Trust of its obligations under, this Agreement, the Remarketing Agreement and
the Trust Agreement will not result in a violation of any existing statute or
order, rule or regulation of any court or governmental agency or body having
jurisdiction over the Trust or any of its assets, the Trust Agreement or any
agreement or other instrument binding upon the Trust; and except for such
consents, approvals, authorizations, registrations or qualifications as may be
required under applicable state securities laws in connection with the purchase
of the Preferred Securities by the Secondary Purchaser, no consent, approval,
authorization or order of, or filing or registration with, any such court or
governmental agency or body is required for the performance by the Trust under
this Agreement, the Remarketing Agreement and the Trust Agreement.

         SECTION 7. Additional Covenants of the Company and the Remarketing
Agent. (a) None of the Company, the Remarketing Agent or any Affiliate of the
Company will sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in the Securities Act) which
could be integrated with the sale of the Securities to the Secondary Purchaser
in a manner that would require the registration under the Securities Act of the
Securities.

          (b) None of the Company, the Remarketing Agent or any Affiliate of the
Company shall solicit any offer to buy or offer to sell the Securities by means

Preferred Securities and prospective purchasers of Preferred Securities
designated by such holders, upon request of such holders or such prospective
purchasers, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act, if applicable.

          (d) The Company shall include in any Offering Memorandum information
substantially in the form set forth in Exhibit I.

          (e) The Company shall advise the Secondary Purchaser promptly and, if
requested by the Secondary Purchaser, to confirm such advice in writing, of (i)
the issuance by any state securities commission of any stop order suspending the
qualification or exemption from qualification of any Preferred Securities for
offering or sale in any jurisdiction, or the initiation of any proceeding for
such purpose by the Commission or any state securities commission or other
regulatory authority, and (ii) the happening of any event that makes any
statement of a material fact made in the Offering Memorandum or incorporated by
reference therein untrue or that requires the making of any additions to or
changes in the Offering Memorandum or any Incorporated Document in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading. The Company shall use every reasonable effort to prevent
the issuance of any stop order or order suspending the qualification or
exemption of the Preferred Securities under any state securities or blue sky
laws and, if at any time any state securities commission shall issue any stop
order suspending the qualification or exemption of the Securities under any
state securities or blue sky laws, the Company shall use every reasonable effort
to obtain the withdrawal or lifting of such order at the earliest possible time.

principal national securities exchange or automatic quotation system upon which
its common stock may be listed or quoted pursuant to requirements of or
agreements with such exchange or system or to the Commission pursuant to the
Exchange Act or any Exchange Act Regulation.

          (g) Until the expiration of two years after the last date of issuance
of the Preferred Securities, the Company shall not, and shall cause its
Affiliates not to, resell any Preferred Securities that were acquired
beneficially or of record by the Company or such affiliate if such Preferred
Securities were "restricted securities" (as such term is defined under Rule
144(a)(3) under the Securities Act) when so acquired unless such resale is
registered pursuant to the Securities Act.

          (h) The Company shall take such steps as shall be necessary to ensure

Investment Company Act and the rules and regulations of the Commission
thereunder.

Securities only from, and will offer and resell the Preferred Securities only

<PAGE>   41
          (b) The Secondary Purchaser is capable of assessing the merits of and
understanding (on its own behalf or through independent professional advice),
and understands and accepts, the terms, conditions and risks of this Agreement,
and of assuming, and assumes, the risks of this Agreement.

         SECTION 9. Payment of Expenses. The Company shall pay all costs, fees

         general application relating to or affecting the enforcement of
         creditors' rights or by general equitable principles;

                  (iii) The Subordinated Notes have been duly authorized and
         established in conformity with the provisions of the Indenture and are
         validly issued and outstanding;

                  (iv) No consent, approval, authorization, order of,
         registration, qualification, or filing of or registration with, any
         court or Governmental Authority or agency is required for the Company's
         execution, delivery and performance of this Agreement, the Company's
         performance of the Remarketing Agreement, the Guarantee Agreement, the
         Indenture and the Subordinated Notes and consummation of the
         transactions contemplated hereby and thereby;

                  (v) (A) The Company is not an "INVESTMENT COMPANY" within the
         meaning of the Investment Company Act and the rules and regulations of
         the Commission thereunder; and (B) the Trust is not an "investment

                  (vi) Assuming the accuracy of the Secondary Purchaser's
         representations, warranties and agreements set forth in Section 8
         hereof, registration of the Preferred Securities, the Subordinated
         Notes or the Guarantee Agreement under the Securities Act is not
         required in connection with the offer, sale and delivery of the
         Preferred Securities to the Secondary Purchaser and qualification of
         the Trust Agreement, the Guarantee Agreement or the Indenture under the
         Trust Indenture Act is not required;

                  (vii) To the best of such counsel's knowledge after due
         inquiry, neither the Company nor any of its Affiliates has directly, or
         through any agent, sold, offered for sale, solicited offers to buy or
         otherwise negotiated in respect of, any security (as defined in the
         Securities Act) which is or will be integrated with the sale of the
         Preferred Securities in a manner that would require the registration
         under the Securities Act of the Preferred Securities.

                  (viii) The Trust is classified as a grantor trust or other
         pass-through entity for United States federal income tax purposes and
         not as an association or publicly traded partnership taxable as a
         corporation; and

                  (ix) The Subordinated Notes are classified as indebtedness for
         United States federal income tax purposes;

In rendering the opinions set forth above, counsel may state that its opinion is
limited to matters governed by the federal laws of the United States of America,
the laws of the State of New York and the General Corporation Law of the State
of Delaware and that such counsel is not admitted in the state of Delaware.

Counsel shall have furnished to the Secondary Purchaser his written opinion, as
counsel to the Company, addressed to the Secondary Purchaser and dated the
Remarketing Settlement Date, in form and substance reasonably satisfactory to
the Secondary Purchaser, to the effect that:

                      (i) The Company has been duly incorporated and is validly

           State of Delaware;

           Agreement and the

           contemplated thereby;

                      (iii) No stockholder of the Company or any other person
           has any preemptive right, right of first refusal or other similar
           right to subscribe for or purchase securities of the Company arising
           (AQ) by operation of the charter or By-Laws of the Company or the
           General Corporation Law of the State of Delaware or (B) to the best
           knowledge of such counsel, otherwise;

                      (iv) The Company is duly qualified as a foreign
           corporation and is in good standing under the laws of each other
           jurisdiction where its ownership, lease, license or operation of
           property or its conduct of business requires such qualification,
           other than in such jurisdiction or jurisdictions where the failure to
           be so qualified and in good standing could not reasonably be expected
           to result in a Material Adverse Change;

                      (v) Each Material Subsidiary of the Company has been duly
           incorporated or formed and is validly existing in good standing under

           operate its properties and conduct its business as currently
           conducted. Each Material Subsidiary is duly qualified as a foreign
           entity, to transact business and is in good standing in each other
           jurisdiction or jurisdictions in which such qualification is

           or the conduct of business, except where the failure to so qualify or
           be in good standing could not reasonably be expected to result in a
           Material Adverse Change. All of the issued and outstanding capital
           stock of each Material Subsidiary has been duly authorized and
           validly issued, is fully paid and nonassessable and is owned by the

           encumbrance or, to the best of such counsel's knowledge, any pending
           or threatened claim;

                      (vi) Neither the Company nor any of its Material
           Subsidiaries is in violation of its charter or by-laws or is in
           Default under any Existing Instrument, except for such Defaults as
           could not, individually or in the aggregate, reasonably be expected
           to result in a Material Adverse Change. The execution, delivery and
           performance by the Company of its obligations under the Transaction
           Documents, the

           purchase of the Common Securities by the Company from the Trust and
           the consummation by the Company of the transactions contemplated in

           ByLaws or other constitutive documents of the Company or any
           Subsidiary, (B) do not and will not conflict with or constitute a
           breach of, Default or a Debt Repayment Trigger Event under, or result

           any assets, properties or operations of the Company or any of its
           Material Subsidiaries pursuant to, or require the consent of any

           in the Credit Agreement as in effect on November 12, 1998), charges
           or encumbrances as would not, individually or in the aggregate,
           result in a Material Adverse Change and (C) will not result in any
           violation of any applicable law or statute or any order, rule,
           regulation or judgment of any court or governmental agency or body
           having jurisdiction over the Company or any of its Material
           Subsidiaries or any of their respective assets, properties or
           operations the result of which could be a Material Adverse Change;

                      (vii) Other than as set forth in the Exchange Act Reports,
           there are no legal or governmental actions, suits or proceedings
           pending or, to the best of such counsel's knowledge, threatened (A)
           against or affecting the Company or any of its subsidiaries, or (B)
           that have as the subject thereof any officer or director of, or
           property owned or leased by, the Company or any of its subsidiaries,

           such action, suit or proceeding might be determined adversely to the
           Company or such subsidiary and (II) any such action, suit or
           proceeding, if so determined adversely, could reasonably be expected
           to result in a Material Adverse Change or adversely affect the

                      (ix) To the best of such counsel's knowledge, the Exchange
           Act Reports, as supplemented by material press releases, at the time
           they were filed did not, and giving effect on the date hereof to the
           transactions contemplated by the Transaction Documents do not,
           contain


                                      A-22
<PAGE>   46
           any untrue statement of a material fact or omit to state a material
           fact necessary in order to make the statements therein, in the light
           of the circumstances under which they were made, not misleading.



In rendering such opinions, such counsel may state that his opinion is limited
to matters governed by Delaware law and that such counsel is not admitted in the
State of New York.

           (d) Opinion of Delaware Counsel. Richards, Layton & Finger, P.A.,
         Delaware counsel for the Company and the Trust, shall have furnished to
         the Purchaser their written opinion addressed to the Secondary
         Purchaser and dated the Remarketing Settlement Date, in form and
         substance reasonably satisfactory to the Secondary Purchaser, to the
         effect that:

                      (i) The Trust has been duly created and is validly
           existing in good standing as a business trust under the Business
           Trust Act and under the Business Trust Act, and the Trust Agreement
           has the trust power and authority to own property and to conduct its
           business, all as described in the Trust Agreement, and to enter into
           and perform its obligations under the Agreement and to perform its
           obligations under each of the Remarketing Agreement, the Preferred
           Securities and the Common Securities;

                      (ii) The Common Securities have been duly authorized by
           the Trust Agreement and are validly issued undivided beneficial
           ownership interests in the assets of the Trust;

                      (iii) The Preferred Securities have been duly authorized
           by the Trust Agreement and, the Preferred Securities are validly
           issued and (subject to qualifications set forth in this paragraph)
           fully paid and non-assessable undivided beneficial interests in the
           assets of the Trust. The holders of the Preferred Securities are, and
           will be entitled to the benefits of the Trust Agreement and, as
           beneficial owners of the Trust, are, and will be entitled to the same
           limitation of personal liability as extended to stockholders of
           private corporations for profit organized under the General
           Corporation Law of the State of Delaware. We note that the holders of
           the Preferred Securities may be obligated, pursuant to the Trust
           Agreement, to (i) provide indemnity and/or security in connection
           with and pay taxes or governmental charges arising from transfers or
           exchanges of Preferred Securities certificates and the issuance of
           replacement Preferred Securities certificates, and (ii) provide


                                      A-23

           the Property Trustee to exercise its rights and powers under the
           Trust Agreement;

                      (iv) Under the Trust Agreement and the Business Trust Act,
           all necessary trust action has been taken to duly authorize the
           execution and delivery by the Trust of this Agreement and the
           Remarketing Agreement;

                      (v) The Trust Agreement constitutes a valid and binding
           obligation of the Company and the Administrative Trustees, and is
           enforceable against the Company and the Administrative Trustees in
           accordance with its terms, except to the extent that enforcement
           thereof may be limited by (i) bankruptcy, insolvency, moratorium,
           receivership, reorganization, liquidation, fraudulent conveyance or
           transfer and other similar laws relating to or affecting the rights
           and remedies of creditors generally, (ii) principles of equity,
           including applicable law relating to fiduciary duties (regardless of
           whether considered and applied in a proceeding in equity or at law),
           and (iii) the effect of applicable public policy on the
           enforceability of provisions relating to indemnification or
           contribution.

                      (vi) The Subordinated Notes are validly issued and
           outstanding and will constitute valid and legally binding obligations
           of the Company and the Administrative Trustees in accordance with
           their terms, except to the extent that enforcement thereof may be
           limited by (i) bankruptcy, insolvency, moratorium, receivership,
           reorganization, liquidation, fraudulent conveyance or transfer and
           other similar laws relating to or affecting the rights and remedies
           of creditors generally, (ii) principles of equity, including
           applicable law relating to fiduciary duties (regardless of whether
           considered and applied in a proceeding in equity or at law), and
           (iii) the effect of applicable public policy on the enforceability of
           provisions relating to indemnification or contribution.

                      (vii) Each of the Guarantee Agreement, the Indenture, the
           Supplemental Indenture (assuming in the case of the Indenture, due
           execution and delivery by the Company and Indenture Trustee, in the
           case of the Guarantee Agreement, due execution and delivery by the
           Company and the Guarantee Trustee and assuming in the case of the
           First Supplemental Indenture, due execution and delivery by the
           Company and the Indenture Trustee) constitutes a valid and binding
           obligation of the Company and the Administrative Trustees, and is
           enforceable against the Company and the Trustees in accordance with
           its


                                      A-24
<PAGE>   48
           terms, except to the extent that enforcement thereof may be limited
           by (i) bankruptcy, insolvency, moratorium, receivership,

           other similar laws relating to or affecting the rights and remedies
           of creditors generally, (ii) principles of equity, including
           applicable law relating to fiduciary duties (regardless of whether
           considered and applied in a proceeding in equity or at law), and
           (iii) the effect of applicable public policy on the enforceability of
           provisions relating to indemnification or contribution.

                      (viii) The Remarketing of the Preferred Securities, the
           purchase by the Trust of the Subordinated Notes, the execution,
           delivery and performance by the Trust of this Agreement and the
           performance by the Trust of the Remarketing Agreement, the
           consummation by the Trust of the transactions contemplated by this
           Agreement and compliance by the Trust with its obligations hereunder
           and thereunder (A) did and do not violate (I) any of the provisions
           of the Certificate of Trust or the Trust Agreement or (II) any
           applicable Delaware law or administrative regulation; and (B) do not
           require any filing with, or authorization, approval, consent,
           license, order, registration, qualification or decree of, any
           Delaware court or Delaware governmental authority or agency.

         In rendering such opinion, such counsel may state that its opinion is
         limited to matters governed by the laws of the State of Delaware.

          (e) Opinion of Counsel for the Secondary Purchaser. On the Remarketing
Settlement Date, the Secondary Purchaser shall have received the written
opinion, dated as of the Remarketing Settlement Date, of counsel selected by the
Secondary Purchaser (and reasonably acceptable to the Company), with respect to
the matters set forth. Such counsel may state that, insofar as such opinion
involves factual matters, they have relied, to the extent they deem proper, upon
certificates of officers of the Company and the Trust and certificates of public
officials.

          (f) Officer's Certificate. The Company shall have furnished to the
Secondary Purchaser a certificate, dated the Remarketing Settlement Date, of any
of its Co-Chief Executive Officers, its President or any Senior Vice President
stating that (i) the representations, warranties and agreements of the Company
and the Trust in Sections 3 and 4 are true and correct as of such Remarketing
Settlement Date; (ii) the Company has complied with all its agreements contained
herein; and (iii) there has been no Material Adverse Change.

<PAGE>   49
accountants for the Company and any other accountants as appropriate, letters,
dated such date, in form and substance satisfactory to the Secondary Purchaser,
containing statements and information of the type ordinarily included in
accountants' "comfort letters" to underwriters with respect to the financial
statements and certain financial information contained or incorporated by
reference in the Offering Memorandum.

          (h) No Adverse Rating Agency Action. Subsequent to the execution and
delivery of this Agreement (i) no downgrading shall have occurred in the rating
accorded the Company's debt securities or preferred stock by any "nationally
recognized statistical rating organization," as that term is defined by the
Commission for purposes of Rule 436(g)(2) of the Securities Act Regulations and
(ii) no such organization shall have publicly announced that it has under
surveillance or review, with possible negative implications, its rating of any
of the Company's debt securities.

          (i) No Market Disruption Event. Subsequent to the execution and
delivery of this Agreement and prior to the Remarketing Settlement Date there
shall not have occurred any of the following: (i) trading or quotation in any of
the Company's securities shall have been, or continue to be, suspended or
limited by the Commission or by the Relevant Exchange, or trading in securities

established on the New York Stock Exchange Inc. by the Commission; (ii) a
general banking moratorium shall have been declared by federal, New York,
Delaware or London authorities and continue to be in effect; (iii) there shall

States or international financial markets, or any substantial change or
development involving a prospective substantial change in the United States' or
international political, financial or economic conditions affecting the
securities markets generally, as in the reasonable judgment of the Secondary
Purchaser is material and adverse and makes it impracticable to sell Preferred
Securities(6) in the manner and on the terms provided herein or to enforce
contracts for the sale of securities; (iv) since the most recent dates as of
which information is given in the Offering Memorandum, in the reasonable
judgment of the Secondary Purchaser, there shall have occurred any Material
Adverse Change; or (v) the Company shall have sustained a loss by strike, fire,
flood, earthquake, accident or other calamity of such character as in the
reasonable judgment of the Secondary Purchaser may interfere materially with

the conduct of the business and operations of the Company regardless of whether
or not such loss shall have been insured.

          (j) Additional Documents. On the Remarketing Settlement Date, counsel
for the Secondary Purchaser shall have been furnished with such documents and
opinions as they may require for the purpose of enabling them to pass upon the
Remarketing and sale of the Preferred Securities as herein contemplated, or in

the fulfillment of any of the conditions, herein contained; and all proceedings
taken by the Company in connection with the sale of the Preferred Securities as
herein contemplated shall be reasonably satisfactory in form and substance to
the Secondary Purchaser.

          (k) Form of Documents. All opinions, letters, evidence and
certificates mentioned above or elsewhere in this Agreement shall be deemed to
be in compliance with the provisions hereof only if they are in form and
substance satisfactory to the Secondary Purchaser.

         SECTION 11. Purchase Default. If, on the Remarketing Settlement Date,
the Secondary Purchaser fails to purchase the liquidation amount of Preferred
Securities or principal amount of Subordinated Notes, as the case may be, such
failure shall constitute either a Renewed Remarketing or a Failed Remarketing,
as determined in accordance with Section 7 of the Remarketing Agreement.

         SECTION 12. Indemnification. (a) Indemnification of the Secondary
Purchaser and Remarketing Agent. The Company agrees to indemnify and hold
harmless each of the Secondary Purchaser and Remarketing Agent, its officers and
employees, and each person, if any, who controls the Secondary Purchaser and
Remarketing Agent within the meaning of the Securities Act and the Exchange Act
against any loss, claim, damage, liability or expense, as incurred, to which the
Secondary Purchaser and Remarketing Agent or such controlling person may become
subject, under the Securities Act, the Exchange Act or other federal or state
statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of the Company), insofar as such loss, claim, damage, liability or
expense (or actions in respect thereof as contemplated below) arises out of or
is based (i) upon any untrue statement or alleged untrue statement of a material
fact contained in any preliminary Offering Memorandum or the final Offering
Memorandum (or any amendment or supplement thereto), or the omission or alleged
omission therefrom of a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; or (ii) in whole or in part upon any inaccuracy in the
representations and warranties of the Company contained herein; or (iii) in
whole


                                      A-27
<PAGE>   51
or in part upon any failure of the Company to perform its obligations hereunder
or under law; or (iv) any act or failure to act or any alleged act or failure to
act by the Secondary Purchaser and Remarketing Agent in connection with, or
relating in any manner to, the Securities or the remarketing contemplated
hereby, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon any matter covered by
clause (i) above, provided that the Company shall not be liable under this
clause (iv) to the extent that a court of competent jurisdiction shall have
determined by a final judgment that such loss, claim, damage, liability or
action resulted directly from any such acts or failures to act undertaken or
omitted to be taken by the Secondary Purchaser or the Remarketing Agent, as the
case may be, through its bad faith, gross negligence or willful misconduct; and
to reimburse each of the Secondary Purchaser and Remarketing Agent, as the case
may be, and each such controlling person for any and all expenses (including the
fees and disbursements of counsel chosen by the Secondary Purchaser or the
Remarketing Agent and reasonably acceptable to the Company) as such expenses are
reasonably incurred by the Secondary Purchaser or the Remarketing Agent, as the
case may be, or such controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the foregoing indemnity
agreement shall not apply to any loss, claim, damage, liability or expense to
the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Company by the Secondary Purchaser or the Remarketing Agent, as the case may be,
expressly for use in any preliminary Offering Memorandum or final Offering
Memorandum (or any amendment or supplement thereto); and provided, further, that
with respect to any preliminary Offering Memorandum, the foregoing indemnity
agreement shall not inure to the benefit of the Secondary Purchaser and
Remarketing Agent from whom the person asserting any loss, claim, damage,
liability or expense purchased Securities, or any person controlling the
Secondary Purchaser or the Remarketing Agent, as the case may be, if copies of
the final Offering Memorandum were timely delivered to the Secondary Purchaser
or the Remarketing Agent, as the case may be, pursuant to Section 2 and a copy
of the final Offering Memorandum (as then amended or supplemented if the Company
shall have furnished any amendments or supplements thereto) was not sent or
given by or on behalf of the Secondary Purchaser or the Remarketing Agent, as
the case may be, to such person, if required by law so to have been delivered,
at or prior to the written confirmation of the sale of the Securities to such
person, and if the final Offering Memorandum (as so amended or supplemented)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. The indemnity agreement set forth in this Section 12 shall be in
addition to any liabilities that the Company may


                                      A-28
<PAGE>   52
otherwise have and shall be in addition to the Company's indemnification
obligations pursuant to the Remarketing Agreement.

          (b) Indemnification of the Company, its Directors and Officers. Each
of the Secondary Purchaser and Remarketing Agent agrees, severally and not
jointly, to indemnify and hold harmless the Company, each of its directors, each
of its officers and each person, if any, who controls the Company within the
meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of the Secondary Purchaser and
Remarketing Agent), insofar as such loss, claim, damage, liability or expense
(or actions in respect thereof as contemplated below) arises out of or is based
upon any untrue or alleged untrue statement of a material fact contained in any
preliminary Offering Memorandum or the final Offering Memorandum (or any
amendment or supplement thereto), or arises out of or is based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any preliminary
Offering Memorandum, the final Offering Memorandum (or any amendment or
supplement thereto), in reliance upon and in conformity with written information
furnished to the Company by the Secondary Purchaser and the Remarketing Agent
expressly for use therein; and to reimburse the Company, or any such director,
officer or controlling person for any and all expenses (including the fees and
disbursements of counsel chosen by any such Person) as such expenses are
reasonably incurred by the Company, or any such director, officer or controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action. The indemnity
agreement set forth in this Section 12 shall be in addition to any liabilities
that the Secondary Purchaser and Remarketing Agent may otherwise have.

          (c) Notifications and Other Indemnification Procedures. Promptly after
receipt by an indemnified party under this Section 12 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 12,
notify the indemnifying party in writing of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party for contribution or
otherwise than under the indemnity agreement contained in this Section 12 or to
the extent it is not prejudiced as a proximate result of such failure. In case
any such action is


                                      A-29
<PAGE>   53
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and
the indemnified party in conducting the defense of any such action or that there
may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval by the
indemnified party of counsel, the indemnifying party will not be liable to such
indemnified party under this Section 12 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
accordance with the proviso to the next preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel (together with local counsel), approved by the
indemnifying party), or (ii) the indemnifying party shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action, in each of
which cases the fees and expenses of counsel shall be at the expense of the
indemnifying party.

          (d) Settlements. The indemnifying party under this Section 12 shall
not be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by Section
12(c) hereof, the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 60 days after receipt by such indemnifying
party of the aforesaid request and (ii) such indemnifying party shall not have
reimbursed the indemnified party in accordance with such request prior to the
date of such


                                      A-30
<PAGE>   54
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement, compromise or consent to the entry
of judgment in any pending or threatened action, suit or proceeding in respect
of which any indemnified party is or could have been a party and indemnity was
or could have been sought hereunder by such indemnified party, unless such
settlement, compromise or consent includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

         SECTION 13. Contribution. If the indemnification provided for in
Section 12 is for any reason held to be unavailable to or otherwise insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount paid or payable by such indemnified party, as
incurred, as a result of any losses, claims, damages, liabilities or expenses
referred to therein (i) in such proportion as is appropriate to reflect the
relative benefits received by each of the Company, the Secondary Purchaser and
Remarketing Agent, from the offering of the Securities pursuant to this
Agreement 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 each of the Company, the Secondary Purchaser and the Remarketing Agent
in connection with the statements or omissions or inaccuracies in the
representations and warranties herein which resulted in such losses, claims,
damages, liabilities or expenses, as well as any other relevant equitable
considerations. The relative benefits received by each of the Company, the
Secondary Purchaser and the Remarketing Agent in connection with the remarketing
of the Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the remarketing of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company, and the total underwriting discount received by the Secondary
Purchaser, the Remarketing Fee received by the Remarketing Agent, bear to the
Remarketing Price. The relative fault of each of the Company, the Secondary
Purchaser and the Remarketing Agent shall be determined by reference to, among
other things, whether any such untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact or any such
inaccurate or alleged inaccurate representation or warranty relates to
information supplied by the Company or the Secondary Purchaser or the
Remarketing Agent, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 12(c), any legal or
other fees or


                                      A-31
<PAGE>   55
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim. The provisions set forth in Section 12(c) with
respect to notice of commencement of any action shall apply if a claim for
contribution is to be made under this Section 13; provided, however, that no
additional notice shall be required with respect to any action for which notice
has been given under Section 12(c) for purposes of indemnification.

         Each of the Company, the Secondary Purchaser and the Remarketing Agent
agree that it would not be just and equitable if contribution pursuant to this
Section 13 were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 13.

         Notwithstanding the provisions of this Section 13, the Secondary
Purchaser shall not be required to contribute any amount in excess of the
underwriting commissions received by it in connection with the Securities
underwritten by it and distributed to the public and the Remarketing Agent shall
not be required to contribute any amount in excess of the Remarketing Fee
received by it in connection with the Securities remarketed by it. 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. For purposes of this Section
13, each officer and employee of the Secondary Purchaser or the Remarketing
Agent, as the case may be, and each person, if any, who controls the Secondary
Purchaser or the Remarketing Agent, as the case may be, within the meaning of
the Securities Act and the Exchange Act shall have the same rights to
contribution as the Secondary Purchaser or the Remarketing Agent, as the case
may be and each director of the Company and each person, if any, who controls
the Company with the meaning of the Securities Act and the Exchange Act shall
have the same rights to contribution as the Company.

         SECTION 14. Termination. The obligations of the Secondary Purchaser
hereunder may be terminated by it by notice given to and received by the Company
prior to delivery of and payment for the Preferred Securities if, prior to that
time, any of the events described in Sections 10(h) and 10(i) shall have
occurred or if the Secondary Purchaser shall decline to purchase the Preferred
Securities for any reason permitted under this Agreement.

         SECTION 15. Survival. The respective indemnities, representations,
warranties and agreements of the Company, the Trust, the Secondary Purchaser and
the Remarketing Agent contained in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall survive the delivery of
and payment for the Securities and shall remain in full force and effect,
regardless


                                      A-32
<PAGE>   56
of any investigation made by or on behalf of any of them or any person
controlling any of them.

         SECTION 16.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF NEW YORK WITHOUT REFERENCE TO
THE CHOICE OF LAW RULES THEREOF.

         SECTION 17. Counterparts. This Agreement may be executed in one or more
counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

         SECTION 18. Headings. The headings herein are inserted for convenience
of reference only and are not intended to be part of, or to affect the meaning
or interpretation of, this Agreement.

         SECTION 19. Notices. Unless otherwise specified, any notices, requests,
consents or other communications given or made hereunder or pursuant hereto
shall be made in writing or transmitted by any standard form of
telecommunication, including telephone, telegraph or telecopy, and confirmed in
writing. All written notices and confirmations of notices by telecommunication
shall be deemed to have been validly given or made when delivered or mailed,

                                    EXHIBIT I

         Each preliminary and final Offering Memorandum shall contain language
to the following effect:

         Each purchaser of the Preferred Securities will be deemed to:

                           (1) represent that it is purchasing the Preferred
                  Securities for its own account or an account with respect to
                  which it exercises sole investment discretion and that it and
                  any such account is a QIB;

                           (2) acknowledge that the Preferred Securities have
                  not been registered under the Securities Act and may not be
                  offered or sold except as set forth below; and

                           (3) agree that if it should resell or transfer the
                  Preferred Securities prior to the expiration of the holding
                  period applicable to sales thereof under Rule 144(k) under the
                  Securities Act (or any successor provision), it will do so
                  only (a) to the Company or any subsidiary thereof, (b) to a
                  QIB in compliance with Rule 144A or (c) a Secondary Purchaser.

         Each purchaser of the Preferred Securities will be required to furnish
to the Secondary Purchaser such certifications, legal opinions or other
information as the Secondary Purchaser may reasonably require to confirm that
the proposed sale is being made pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act.

         Until sold in a transaction that is registered under the Securities Act
or that is exempt from such registration requirements pursuant to Rule 144 under
the Securities Act, each certificate representing a Preferred Security will bear
the following legend:

         THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY
NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED
INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (2)
AGREES THAT IT WILL NOT PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE
TO SALES OF THE SECURITIES EVIDENCED


                                       I-1

RESELL OR OTHERWISE TRANSFER THE SECURITIES EVIDENCED HEREBY EXCEPT (A) TO
HERCULES INCORPORATED OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT OR (C)
TO A SECONDARY PURCHASER (AS DEFINED IN THE AMENDED AND RESTATED TRUST AGREEMENT
OF HERCULES TRUST V DATED AS OF NOVEMBER 12, 1998 (THE "TRUST AGREEMENT") THAT
HAS ENTERED INTO A SECONDARY PURCHASE AGREEMENT (AS DEFINED IN THE TRUST
AGREEMENT) WITH THE TRUST, (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO
WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
EFFECT OF THIS LEGEND AND (4) AGREES, WITH RESPECT TO ANY TRANSFER OCCURRING
PRIOR TO THE REMARKETING DATE ON WHICH REPLACEMENT SECURITIES ARE ISSUED, TO
PROVIDE TO THE PROPERTY TRUSTEE A DULY EXECUTED CERTIFICATE SUBSTANTIALLY TO THE
EFFECT OF CLAUSES (1), (2) AND (3), ABOVE. THIS LEGEND WILL BE REMOVED AFTER THE
EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO THE SALES OF THE SECURITY
EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT.

         FROM AND AFTER THE REMARKETING SETTLEMENT DATE ON WHICH REPLACEMENT
SECURITIES ARE ISSUED, THIS CERTIFICATE SHALL REPRESENT ONLY THE RIGHT TO
RECEIVE THE REMARKETING PRICE, AS PROVIDED IN THE TRUST AGREEMENT, AND SHALL NO
LONGER REPRESENT AN OBLIGATION OF OR INTEREST IN THE TRUST.

         Each preliminary and final Offering Memorandum shall also contain
language to the following effect:

                  "Each person receiving this Offering Memorandum acknowledges
         that (i) such person has been afforded an opportunity to request from
         the Company and to review all additional information considered by it
         to be necessary to verify the accuracy of or to supplement the
         information herein, (ii) it has not relied on the Secondary Purchaser
         or any person affiliated with the Secondary Purchaser in connection
         with its investigation of the accuracy of such information or its
         investment decision and (iii) no person has been authorized to give any
         information or to make any representation concerning the Company or the
         Preferred Securities offered hereby other than as contained herein and
         information given by duly authorized officers and employees of the
         Company in

NATIONSBANC MONTGOMERY SECURITIES LLC
600 Montgomery Street
San Francisco, California 94111


Ladies and Gentlemen:

         INTRODUCTORY. Hercules Incorporated (the "COMPANY"), a Delaware
corporation, proposes to issue and sell to NationsBanc Montgomery Securities
LLC, as underwriter (the "UNDERWRITER"), an aggregate number of shares (the
"PURCHASE SHARES") of its common stock, no par value (the "COMMON STOCK"), with
an aggregate Public Offering Price (as defined herein) equal to $200,000,000
(the "AGGREGATE PUBLIC OFFERING PRICE").

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-3 (No. 333-63423) and
Pre-effective Amendment No. 1 thereto for the registration of, among other
securities, the Purchase Shares under the Securities Act of 1933, as amended
(the "1933 ACT"), and the offering thereof from time to time in accordance with
Rule 415 of the rules and regulations of the Commission under the 1933 Act (the
"1933 ACT REGULATIONS"). Such registration statement has been declared effective
by the Commission, and the Company has filed and will file such post-effective
amendments and supplements thereto as may be required prior to the sale of
Purchase Shares pursuant thereto, and each such post-effective amendment has
been or will be declared effective by the Commission. Such registration
statement (as so amended or supplemented, if applicable), including the
information, if any, deemed to be a part thereof pursuant to Rule 430A(b) of the
1933 Act Regulations (the "RULE 430A INFORMATION") or Rule 434(d) of the 1933
Act Regulations (the "RULE 434 INFORMATION"), is referred to herein as the
"REGISTRATION STATEMENT"; and the final prospectus and the final prospectus
supplement relating to the offering of the Purchase Shares, in the form
furnished to the Underwriter by the Company for use in connection with each
offering of the Purchase Shares, are collectively referred to herein as the
"PROSPECTUS"; provided, however, that all
<PAGE>   3
references to the "REGISTRATION STATEMENT" and the "PROSPECTUS" shall also be
deemed to include all documents incorporated therein by reference pursuant to
the Securities Exchange Act of 1934, as amended (the "1934 ACT"), prior to the
time the applicable final prospectus and the final prospectus supplement with
respect to the offering of Purchase Shares on each Pricing Date are furnished to
the Underwriter by the Company; provided, further, that if the Company files a
registration statement with the Commission pursuant to Rule 462(b) of the 1933
Act Regulations (the "RULE 462(B) REGISTRATION STATEMENT"), then, after such
filing, all references to "REGISTRATION STATEMENT" shall also be deemed to
include the Rule 462(b) Registration Statement; and provided, further, that if
the Company elects to rely upon Rule 434 of the 1933 Act Regulations, then all
references to "PROSPECTUS" shall also be deemed to include the final or
preliminary prospectus and the applicable term sheet or abbreviated term sheet
(the "TERM SHEET"), as the case may be, in the forms first furnished to the
Underwriter by the Company for use in connection with each offering of the
Purchase Shares in reliance upon Rule 434 of the 1933 Act Regulations, and all
references in this Forward Underwriting Agreement to the date of the Prospectus
shall mean the date of the Term Sheet. A "PRELIMINARY PROSPECTUS" shall be
deemed to refer to any prospectus used before the Registration Statement became
effective and any prospectus that omitted, as applicable, the Rule 430A
Information, the Rule 434 Information or other information to be included upon
pricing in a form of prospectus filed with the Commission pursuant to Rule
424(b) of the 1933 Act Regulations that was used after such effectiveness but
prior to the delivery of the applicable final prospectus and the final
prospectus supplement in the forms first furnished to the Underwriter by the
Company. For purposes of this Forward Underwriting Agreement, all references to
the Registration Statement, Prospectus, Term Sheet or preliminary prospectus or
to any amendment or supplement to any of the foregoing shall be deemed to
include any copy filed with the Commission pursuant to its Electronic Data
Gathering, Analysis and Retrieval system ("EDGAR").

         All references in this Forward Underwriting Agreement to financial
statements and schedules and other information which is "contained," "included"
or "stated" (or other references of like import) in the Registration Statement,

         of the Company or any of its Material Subsidiaries pursuant to, or
         require the consent of any other party to, any Existing Instrument,
         except for such conflicts, breaches, Defaults, liens (other than liens
         created by or contemplated in the Credit Agreement as in effect on the
         date hereof), charges or encumbrances or failure to obtain consent as
         would not, individually or in the aggregate, result in a Material
         Adverse


                                       13

         Change and (C) will not result in any violation of any applicable law
         or statute or any order, rule, regulation or judgment of any court or
         governmental agency or governmental body having jurisdiction over the
         Company or any of its Material Subsidiaries or any of their respective
         assets, properties or operations the result of which could be a
         Material Adverse Change.

                  (v) No consent, approval, authorization, order, registration,
         qualification or filing of or with any court or governmental agency or
         body having jurisdiction over the Company or any of its Material
         Subsidiaries or any of their respective properties is required for the
         due authorization, execution and delivery by the Company of, and the
         compliance by the Company with all the terms of, this Forward
         Underwriting Agreement or the consummation by the Company of the
         transactions contemplated hereby except such as have been obtained or
         made by the Company, as may be required by the securities or Blue Sky
         laws of the various States in connection with the offer and sale of the
         Purchase Shares or where the failure to obtain such consent, approval,
         authorization, order, registration, qualification or make such filing
         will not adversely affect such authorization, execution or delivery of
         this Forward Underwriting Agreement, the compliance with the terms
         hereof or the consummation by the Company of the transactions
         contemplated hereby.

          (b) Compliance with Registration Requirements. (i) The Company meets
the requirements for use of Form S-3 under the 1933 Act. The Registration
Statement has been declared effective by the Commission under the 1933 Act. The
Company has complied to the Commission's satisfaction with all requests of the
Commission for additional or supplemental information. No stop order suspending
the effectiveness of the Registration Statement is in effect and no proceedings
for such purpose have been instituted or are pending or, to the best knowledge
of the Company, are contemplated or threatened by the Commission.

                  (ii) Each preliminary prospectus and each Prospectus when
         filed complied in all material respects with the 1933 Act, and each
         preliminary prospectus and each Prospectus delivered to the Underwriter
         for use in connection with the offering of the Purchase Shares pursuant
         to this Forward Underwriting Agreement will, at the time of such
         delivery, be identical to any electronically transmitted copies thereof
         filed with the Commission pursuant to EDGAR, except such variation as
         may be permitted or required by Regulation S-T under the 1933 Act. The
         Registration Statement and any post-effective amendment thereto, at the
         time it became effective and at all subsequent times, complied and will
         comply in all material respects with the 1933 Act and the 1933 Act


                                       14
<PAGE>   16
         Regulations and did not and will not contain any 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. The
         Prospectus, as amended or supplemented, as of its date and at all
         subsequent times, did not and will not contain any untrue statement of
         a material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. If the Company elects to rely
         upon Rule 434 of the 1933 Act Regulations, the Company will comply with
         the requirements of Rule 434. Notwithstanding the foregoing, the
         representations and warranties set forth in this subsection do not
         apply to statements in or omissions from any Registration Statement or
         any post-effective amendment thereto or any Prospectus or any
         amendments or supplements thereto made in reliance upon and in
         conformity with information furnished to the Company in writing by the
         Underwriter expressly for use therein.

                  (iii) The documents incorporated or deemed to be incorporated
         by reference in the Registration Statement and the Prospectus, at the
         time they were or hereafter are filed with the Commission, complied and
         will comply in all material respects with the requirements of the 1934
         Act and the rules and regulations of the Commission thereunder (the
         "1934 ACT REGULATIONS").

                  (iv) There are no actions, suits, proceedings, inquiries or
         investigations before or brought by any legal or governmental agency or
         body, now pending, or to the knowledge of the Company threatened,
         against or affecting the Company or any of its Material Subsidiaries
         that are required to be disclosed in the Registration Statement and the
         Prospectus (other than as stated therein), or which could reasonably be
         expected to result in a Material Adverse Change, or adversely affect
         the consummation of the transactions contemplated under this Forward
         Underwriting Agreement. The aggregate of all pending legal or
         governmental proceedings to which the Company or any of its Material
         Subsidiaries is a party or of which any of their respective assets,
         properties or operations is the subject, which are not described in the
         Registration Statement and the Prospectus, including ordinary routine
         litigation incidental to the business, could not reasonably be expected
         to result in a Material Adverse Change.

          (c) Offering Materials Furnished to Underwriters. The Company has
delivered to the Underwriter one complete manually signed copy of the
Registration Statement and of each consent and certificate of experts filed as a
part thereof, and conformed copies of such Registration Statement (without


                                       15
<PAGE>   17
exhibits) and preliminary prospectuses and the related Prospectus, as amended or
supplemented, in such quantities and at such places as the Underwriter has
reasonably requested.

          (d) Financial Statements. The financial statements of the Company
included in the Registration Statement and the Prospectus, together with the
related schedules and notes, as well as those financial statements, schedules
and notes of any other entity included therein, present fairly the financial
position of the Company and its consolidated subsidiaries, or such other entity
as the case may be as of and at the dates indicated and the statement of
operations, stockholders' equity and cash flows of the Company and its
consolidated subsidiaries, or such other entity, as the case may be, for the
periods specified. Such financial statements have been prepared in conformity
with generally accepted accounting principles ("GAAP") applied on a consistent
basis throughout the periods involved. The supporting schedules, if any,
included in the Registration Statement and the Prospectus 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 and the Prospectus. In addition, any pro forma financial
statements of the Company and its consolidated subsidiaries and the related
notes thereto included in the Registration Statement and the Prospectus have
been prepared in accordance with the Commission's rules and guidelines with
respect to pro forma financial statements and have been properly compiled on the
bases described therein, and the assumptions used in the preparation thereof are
reasonable and the adjustments used therein are appropriate to give effect to
the transactions and circumstances referred to therein but the pro forma
financial statements may differ from actual results. The financial data, if any,
set forth in the Prospectus under the captions "Prospectus Summary--Summary
Selected Financial Data," "Selected Financial Data" and "Capitalization" (or
similar captions) fairly present the information set forth therein on a basis
consistent with that of the audited financial statements contained in the
related Registration Statement.

          (e) Authorization of the Common Stock. Any shares of Common Stock to
be delivered by the Company under this Forward Underwriting Agreement have been
or, prior to such delivery, will be duly authorized for issuance and delivery
pursuant to this Forward Underwriting Agreement and, when issued and delivered
by the Company pursuant to this Forward Underwriting Agreement, will be validly
issued, fully paid and non-assessable.

          (f) No Applicable Registration or Other Similar Rights. There are no
persons with registration or other similar rights to have any equity or debt


                                       16
<PAGE>   18
securities registered for sale under the Registration Statement, except for such
rights as have been duly waived.

          (g) Independent Accountants. Each of the accountants who certified
financial statements and any supporting schedules thereto filed as part of the
Registration Statement and included in the Prospectus are independent public or
certified public accountants as required by the 1933 Act, the 1933 Act
Regulations, the 1934 Act and the 1934 Act Regulations.

          (h) No Material Adverse Change in Business. 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, any development that could reasonably be expected to result in a
material adverse change in the condition, financial or otherwise, in or
affecting the earnings, business, operations, financial position or prospects,
whether or not arising from transactions in the ordinary course of business, of
the Company and its subsidiaries, considered as one entity (a "MATERIAL ADVERSE
CHANGE"), (B) there have been no transactions entered into by the Company or any
of its Material Subsidiaries, other than those arising in the ordinary course of
business, which are, individually or in the aggregate, material with respect to
the Company and its subsidiaries, considered as one enterprise and (C) except
for regular dividends on the Company's Common Stock or preferred stock (which
dividends include amounts, sometimes called "dividend equivalents," paid under
the Company's employee benefit and compensation plans on the Common Stock grants
(whether options, restricted stocks or other) under such plans on the Common
Stock, but only to the extent such amounts do not exceed the amounts of ordinary
cash dividends that would be payable were such Common Stock grants treated as
Common Stock) in amounts per share that are consistent with past practice or the
applicable charter document or supplement thereto, respectively, there has been
no dividend or distribution of any kind declared, paid or made by the Company on
any class of its capital stock.

          (i) Good Standing of Material Subsidiaries. Each Material Subsidiary
is a duly and validly existing corporation or entity and is in good standing
under the laws of the jurisdiction of its incorporation or organization, has all
corporate power and authority to own, lease, license and operate its properties
and to conduct its business as currently conducted and is duly qualified as a
foreign entity in good standing in each other jurisdiction where its ownership,
lease, license or operation of property or the conduct of its business requires
such qualification, other than in such jurisdiction or jurisdictions where the
failure to be so qualified and in good standing could not reasonably be expected
to result in a Material Adverse Change. All of the issued and outstanding
capital stock of each Material Subsidiary have been duly authorized and validly
issued, is fully paid


                                       17
<PAGE>   19
and non-assessable and is owned by the Company, directly or through
subsidiaries, free and clear of any security interest, mortgage, pledge, lien
(other than those created by or contemplated in the Credit Agreement as in
effect on the date hereof), encumbrance or claim. None of the outstanding shares
of capital stock of any Material Subsidiary were issued in violation of
preemptive or other similar rights of any securityholder of such Material
Subsidiary.

          (j) Capitalization. The authorized, issued and outstanding capital
stock of the Company is as set forth in the Prospectus under the caption,
"Capitalization" (or any other similar caption) (other than for subsequent
issuances, if any, pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding options or warrants described in the
Prospectus). Such shares of capital stock have been duly authorized and validly
issued by the Company and are fully paid and non-assessable and have been issued
in compliance with federal and state securities laws. The Common Stock
(including the Purchase Shares) conforms in all material respects to the
description thereof contained in the Prospectus. None of the outstanding shares
of Common Stock was issued in violation of preemptive rights, rights of first
refusal or other similar rights to subscribe for or purchase securities of the
Company. There are no authorized or outstanding options, warrants, preemptive
rights, rights of first refusal or other rights to purchase, or equity or debt
securities convertible into or exchangeable or exercisable for, any capital
stock of the Company or any of its subsidiaries other than those accurately
described in the Registration Statement and the Prospectus.

          (k) Stock Exchange Listing. All shares of Common Stock to be issued
hereunder have been or, prior to such issuance, will be approved for inclusion
or listing on the principal national securities exchange or automated quotation
system on which the Common Stock is listed or quoted (the "RELEVANT EXCHANGE"),
subject only to official notice of issuance.

          (l) Intellectual Property Rights. Except as otherwise disclosed in the
Prospectus, the Company and each Material Subsidiary owns, leases, licenses or
otherwise possesses adequate trademarks, service marks, trade names, patents,
patent rights, copyrights, licenses, inventions, approvals and other
intellectual property (collectively, "INTELLECTUAL PROPERTY") necessary to
conduct its business as now conducted. Neither the Company nor any of its
Material Subsidiaries has received any written notice of any infringement of or
conflict with asserted rights of others with respect to any Intellectual
Property which infringement or conflict, individually or in the aggregate, could
be reasonably expected to result in a Material Adverse Change.


                                       18
<PAGE>   20
          (m) Possession of Licenses and Permits. Each of the Company and its
Material Subsidiaries possesses such permits, licenses, approvals, consents and
other authorizations (collectively, "GOVERNMENTAL LICENSES") issued by the
appropriate federal, state, local or foreign regulatory agencies or bodies as
are necessary to conduct the business now operated by it except as could not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change. The Company and its Material Subsidiaries are in compliance with
the terms and conditions of all such Governmental Licenses, except where the
failure so to comply could not, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Change. All of the Governmental
Licenses are valid and in full force and effect, except where the invalidity of
such Governmental Licenses or the failure of such Governmental Licenses to be in
full force and effect could not, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Change. Neither the Company nor any of
its Material Subsidiaries has received any written notice of proceedings
relating to the revocation or modification of any such Governmental Licenses
which, individually or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, could reasonably be expected to result in a
Material Adverse Change.

          (n) Company Not an "Investment Company." The Company is not, and upon
the issuance and sale of the Purchase Shares as herein contemplated and the
application of the net proceeds therefrom as described in the Prospectus will
not be, an "investment company" within the meaning of the Investment Company Act
of 1940, as amended (the "INVESTMENT COMPANY ACT") and the rules and regulations
of the Commission thereunder.

          (o) Price Stabilization or Manipulation. The Company has not taken and
will not take, directly or indirectly, any action designed to or that could be
reasonably expected to cause or result in stabilization or manipulation of the
price of the Common Stock to facilitate the sale or resale of any shares of
Common Stock delivered hereunder. Notwithstanding the foregoing, the repurchase
by the Company from time to time pursuant to a share repurchase program
authorized by the Board of Directors of the Company, if conducted in accordance
with applicable law (including without limitation Regulation M under the 1934
Act), shall not be deemed or considered to be such stabilization or
manipulation.

          (p) Related Party Transactions. There are no business relationships or
related party transactions involving the Company or any subsidiary or any other
person required to be described in the Prospectus that have not been described
as required.


                                       19

          (q)   Environmental Laws.

         (i) Except as would not have or could not be reasonably expected to
result in a Material Adverse Change, or as is not otherwise disclosed in the
Prospectus:

          (A) Each of the real properties owned by the Company or any of its
         Material Subsidiaries (the "REAL PROPERTIES") and all operations at the
         Real Properties are in compliance with all applicable Environmental
         Laws, and there is no violation of any Environmental Law with respect
         to the Real Properties or the businesses operated by the Company or any
         of its Material Subsidiaries (the "BUSINESSES"), and there are no
         conditions relating to the Businesses or Real Properties that could be
         reasonably expected to give rise to liability under any applicable
         Environmental Laws.

          (B) Neither the Company nor any of its Material Subsidiaries has
         received any written notice of, or inquiry from any governmental
         authority regarding, any violation, alleged violation, non-compliance,
         liability or potential liability regarding Hazardous Materials or
         compliance with Environmental Laws with regard to any of the Real
         Properties or the Businesses, nor does the Company or any of its
         Material Subsidiaries have knowledge or reason to believe that any such
         notice is being threatened.

          (C) Hazardous Materials have not been transported or disposed of from
         the Real Properties, or generated, treated, stored or disposed of at,
         on or under any of the Real Properties or any other location, in each
         case by, or on behalf or with the permission of, the Company or any of
         its Material Subsidiaries.

          (D) No judicial proceeding or governmental or administrative action is
         pending or, to the knowledge of the Company, threatened, under any
         Environmental Law to which the Company or any Material Subsidiary, is
         or, to the best knowledge of the Company, will be named as a party, nor
         are there any consent decrees or other decrees, consent orders,
         administrative orders or other orders, or other administrative or
         judicial requirements outstanding under any Environmental Law with
         respect to the Company or any of its Material Subsidiaries, the Real
         Properties or the Businesses.

          (E) There has been no release or, to the best knowledge of the Company
         or any Material Subsidiary, threat of release of Hazardous Materials at
         or from the Real Properties, or arising from or related to the


                                       20
<PAGE>   22
         operations (including, without limitation, disposal) of the Company or
         any of its Material Subsidiaries in connection with the Real Properties
         or otherwise in connection with the Businesses, in violation of, or in
         amounts or in a manner that could give rise to liability under,
         Environmental Laws.

          (F) None of the Real Properties contains, or has previously contained,
         any Hazardous Materials at, on or under the Real Properties in amounts
         or concentrations that, if released, constitute or constituted a
         violation of, or would give rise to liability under, Environmental
         Laws.

          (G) Neither the Company nor any of its Material Subsidiaries, has
         assumed any liability of any Person (other than the Company or one of
         its Material Subsidiaries) under any Environmental Law.

                  (ii) The Company has adopted procedures that are designed to
         (A) ensure that for the Company and each of the its Material
         Subsidiaries, each of their respective operations and each of the
         properties owned or leased by each such entity remains in compliance
         with applicable Environmental Laws, to the extent that the failure to
         comply with such Environmental Laws would result in or could be
         reasonably expected to result in a Material Adverse Change and (B)
         manage, to the same extent as and in accordance with the practices of
         companies engaged in the same or a similar business, any liabilities or
         potential liabilities that each such entity, any of its respective
         operations and each of the properties owned or leased by such entity
         may have under applicable Environmental Laws.

Securities. On or prior to the Initial Pricing Date, the Trust Preferred
Securities (or, if Subordinated Notes shall have been distributed with respect
to the Trust Preferred


                                       23
<PAGE>   25
Securities, such Subordinated Notes) shall have been either (i) remarketed
pursuant to the terms of the Remarketing Agreement or (ii) mandatorily redeemed
or matured in accordance with their terms pursuant to the applicable provisions
of the Trust Agreement and Indenture and, in each case, the holders of the Trust
Preferred Securities or Subordinated Notes, as the case may be, shall have
received the proceeds of such remarketing or mandatory redemption (or maturity),
as the case may be.

          (i) Effect of Failure of Conditions. If any condition specified in
this Section 4 is not satisfied with respect to the purchase and settlement of
Purchase Shares on any Pricing Date or Purchase Date when and as required to be
satisfied, the Underwriter shall be released from its obligations hereunder with
respect thereto.

          (j) Ratification. The Board of Directors of the Company shall have
ratified this Agreement and actions to be taken by the Company in connection
herewith.

         SECTION 5.  Registration Agreements.

         The Company covenants and agrees with the Underwriter as follows:

          (a) Without limiting the generality of the provisions of Sections 4(d)
and 5(c), during the period beginning on the date hereof and ending on the date
all Purchase Shares have been sold pursuant to the Registration Statement (the
"EFFECTIVENESS PERIOD"), prior to amending or supplementing the Registration
Statement or the Prospectus, the Company shall furnish to the Underwriter for
review a copy of each such proposed amendment or supplement that could
reasonably relate to the offer and sale of Purchase Shares, and the Company
shall not file any such proposed amendment or supplement to which the
Underwriter reasonably objects within 5 days of receipt thereof.

          (b) During the Effectiveness Period, the Company shall promptly advise
the Underwriter in writing (A) of the receipt of any comments of, or requests
for additional or supplemental information from, the Commission regarding the
Registration Statement, (B) of the time and date of any filing of any
post-effective amendment to the Registration Statement or any amendment or
supplement to any related preliminary prospectus or the Prospectus, (C) of the
time and date that any post-effective amendment to the Registration Statement
becomes effective, (D) of the occurrence of any event or the existence of any
condition as a result of which it is necessary to amend or supplement the
Prospectus so that such Prospectus does not include an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the


                                       24
<PAGE>   26
circumstances when the Prospectus is delivered to a purchaser of Common Stock,
not misleading, and (E) of the issuance by the Commission of any stop order
suspending the effectiveness of such Registration Statement or any
post-effective amendment thereto or of any order preventing or suspending the
use of any related preliminary prospectus or the Prospectus, or of any
proceedings to remove, suspend or terminate from listing or quotation the Common
Stock from the Relevant Exchange, or, to the best knowledge of the Company, of
the threatening or initiation of any proceedings for any of such purposes. If
the Commission shall enter any such stop order at any time, the Company shall
use its best efforts to obtain the lifting of such order at the earliest
possible moment. Additionally, the Company agrees that it shall comply with the
provisions of Rules 424(b), 430A and 434, as applicable, under the 1933 Act and
will use its reasonable efforts to confirm that any filings made by the Company
under such Rule 424(b) were received in a timely manner by the Commission.

          (c) If, during the Effectiveness Period for any Registration
Statement, any event shall occur or condition exist as a result of which it is
necessary to amend or supplement the related Prospectus so that such Prospectus
does not include an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances when the Prospectus is delivered to a purchaser of Common
Stock, not misleading, or if in the opinion of the Underwriter it is otherwise
necessary to amend or supplement such Prospectus to comply with law, the Company
agrees to prepare promptly, file (subject to Section 5(a)) with the Commission
and furnish at its own expense to the Underwriter, amendments or supplements to
such Prospectus so that the Prospectus as so amended or supplemented will not
include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances when the Prospectus is delivered to a purchaser of Common Stock,
not misleading or so that such Prospectus, as so amended or supplemented, will
comply with law.

          (d) The Company agrees to furnish the Underwriter, without charge,
during the Effectiveness Period, as many copies of the Prospectus and any
amendments and supplements thereto as the Underwriter may reasonably request.

          (e) The Company shall cooperate with the Underwriter to qualify or
register the Purchase Shares registered pursuant to the Registration Statement
for sale under (or obtain exemptions from the application of) the state
securities or blue sky laws of those jurisdictions designated by the
Underwriter, shall comply with such laws and shall continue such qualifications,
registrations and exemptions in effect so long as required for the distribution
of the Purchase Shares. The Company shall not be required to qualify as a
foreign corporation or to take any action that would subject it to general
service of process in any such


                                       25
<PAGE>   27
jurisdiction where it is not presently qualified or where it would as a result
of such action be subject to taxation as a foreign corporation. The Company will
advise the Underwriter promptly of the suspension of the qualification or
registration of (or any exemption therefrom with respect to) such Purchase
Shares for offering, sale or trading in any jurisdiction or any initiation or
threat of any proceeding for any such purpose, and in the event of the issuance
of any order suspending such qualification, registration or exemption, the
Company shall use its best efforts to obtain the withdrawal thereof at the
earliest possible moment.

         SECTION 6. Additional Covenants of the Company.

         The Company further covenants and agrees with the Underwriter as
follows:

          (a) During the Effectiveness Period, the Company shall continue to
engage and maintain, at its expense, a registrar and transfer agent for the
Common Stock.

          (b) During the Effectiveness Period, the Company will timely file such
reports pursuant to the 1934 Act as are necessary in order to make generally
available to its securityholders as soon as practicable an earnings statement
for the purposes of, and to provide the benefits contemplated by, the last
paragraph of Section 11(a) of the 1933 Act.

          (c) During the Effectiveness Period, the Company shall file, on a
timely basis, with the Commission and the Relevant Exchange all reports and
documents required to be filed under the 1934 Act or the rules of the Relevant
Exchange.

          (d) During the Effectiveness Period, the Company shall furnish to the
Underwriter (A) at the time delivered to stockholders, copies of the Annual
Report of the Company containing the balance sheet of the Company as of the
close of such fiscal year and statements of income, stockholders' equity and
cash flows for the year then ended and the opinion thereon of the Company's
independent public or certified public accountants; (B) as soon as practicable
after the filing thereof, unless available to the Underwriter on EDGAR or the
Company's website, copies of each proxy statement, Annual Report on Form 10- K,
Quarterly Report on Form 10-Q, Current Report on Form 8-K or other report filed
by the Company with the Commission or any securities exchange or automated
quotation system; and (C) as soon as available, copies of any report or
communication of the Company mailed generally to holders of its capital stock.

          (e) At all times during the Effectiveness Period, if requested by the
Underwriter, the Company shall cause to be delivered to the Underwriter such


                                       26
<PAGE>   28
information, documents and opinions as they may reasonably require for the
purposes of enabling it to pass upon the issuance and delivery of the Purchase
Shares as contemplated herein or in order to evidence the accuracy of any of the
representations and warranties, or the satisfaction of any of the conditions or
agreements herein contained.

          (f) The Company will reserve and keep available at all times, free of
preemptive or other similar rights, a sufficient number (the "RESERVE NUMBER")
of shares (which, in any event, shall not be less than 20,000,000 (as may be
adjusted from time to time pursuant to Section 8)) of Common Stock and capacity
on the Registration Statement for the purpose of enabling the Company to satisfy
its obligations to issue and deliver the Purchase Shares hereunder.

          (g) During the period from the date hereof until the earlier of the
final day of the Dribble-out Period or any earlier termination of this Forward
Underwriting Agreement, the Company will not, without the prior written consent
of the Underwriter (which consent may be withheld at the reasonable discretion
of the Underwriter) sell or offer or announce the offering of, or file any
registration statement under the 1933 Act in respect of, or enter into any
agreement or arrangement providing for the offer or sale of, any shares of
Common Stock, except in the case of a merger of the Company; provided, however,
that the Company may issue shares of its Common Stock pursuant to any stock
option, stock bonus or other stock plan or arrangement described in the
Prospectus and may issue securities convertible into Common Stock and the Common
Stock underlying such securities.

         SECTION 7.  Acceleration of Commencement Date.

          (a) Subject to Section 4(h), if the Closing Price of the Common Stock,
as determined by the Underwriter, on any day prior to the Commencement Date is
less than the Trigger Price (a "STOCK PRICE ACCELERATION EVENT"), then
Commencement Date shall be accelerated to the date that is the earliest to occur
of (x) the nineteenth day immediately succeeding the date on which such Stock
Price Acceleration Event shall have occurred, (y) the Trading Day immediately
following the Remarketing Settlement Date, (as defined in the Remarketing
Agreement) on which the Remarketing Agent (as defined in the Remarketing
Agreement) shall have received the proceeds of the related Remarketing (as
defined in the Remarketing Agreement), but in no event later than the third
Scheduled Trading Day prior to November 10, 1999.

          (b) If the Company shall redeem the Subordinated Notes as a result of
a Failed Remarketing (as defined in the Remarketing Agreement) prior to the
Commencement Date, then the Commencement Date shall be accelerated to the


                                       27
<PAGE>   29
Trading Day immediately following the date of such redemption (a "COMPANY
ACCELERATION").

          (c) The Company may, upon three Business Days' written notice to the
Underwriter, elect to accelerate the Commencement Date to any scheduled Trading
Day after the conditions set forth in Section 4(h) have been satisfied.

This Section 7 shall be subject in all respects to the provisions of Section 12.

         SECTION 8.  Adjustments to Trigger Price and Reserve Number.

         Following the declaration of any Potential Adjustment Event, the
Underwriter shall determine (after consultation with the Company) whether such
Potential Adjustment Event has a diluting or concentrative effect on the
theoretical value of the Common Stock and, if so, shall make the corresponding
adjustment(s), if any, to the Trigger Price and the Reserve Number. The
Underwriter may, but need not, determine the appropriate adjustment(s) by
reference to the adjustment(s) in respect of such Potential Adjustment Event
made by an options exchange to options on the Common Stock traded on that
options exchange. In the event of any merger, consolidation or reorganization of
the Company, the Underwriter shall determine the appropriate Trigger Price and
Reserve Number as a result of such event.

         SECTION 9.  Expenses.

         The Company agrees to pay all costs, fees and expenses incurred in
connection with the performance of its obligations hereunder and in connection
with the transactions contemplated hereby, including without limitation (a) all
costs and expenses incident to the authorization, issuance, sale and delivery of
the Purchase Shares (including all printing and engraving costs), (b) all fees
and expenses of the registrar and transfer agent of the Common Stock, (c) all
necessary issue, transfer and other stamp taxes in connection with the issuance
and delivery of the Purchase Shares to the Underwriter, (d) all fees and
expenses of the Company's counsel, independent public or certified public
accountants and other advisors, (e) all costs and expenses incurred in
connection with the preparation, printing, filing, shipping and distribution of
any Registration Statement (including financial statements, exhibits, schedules,
consents and certificates of experts), each related preliminary prospectus and
the related Prospectus, and all amendments and supplements thereto, and this
Forward Underwriting Agreement, (f) all filing fees and other expenses incurred
by the Company or the Underwriter in connection with qualifying or registering
(or obtaining exemptions from the qualification or registration of) any Common
Stock delivered hereunder for offer and sale under the state securities or blue
sky


                                       28
<PAGE>   30
laws and, if requested by the Underwriter, preparing and printing a "BLUE SKY
SURVEY" or memorandum, and any supplements thereto, advising the Underwriter of
such qualifications, registrations and exemptions, (g) the fees and expenses
associated with listing or including any shares of Common Stock delivered
hereunder on the Relevant Exchange, (h) the fees and expenses of counsel for the
Underwriter and its Affiliates incurred in connection with the transactions
contemplated by this Forward Underwriting Agreement and (i) all other fees,
costs and expenses referred to in Item 13 or Item 14, as the case may be, of
Part II of the Registration Statement.

         SECTION 10.  Indemnification.

          (a) Indemnification of the Underwriter. The Company agrees to
indemnify and hold harmless the Underwriter, its officers and employees, and
each person, if any, who controls the Underwriter within the meaning of the 1933
Act and the 1934 Act against any loss, claim, damage, liability or expense, as
incurred, to which the Underwriter or such controlling person may become
subject, under the 1933 Act, the 1934 Act or other federal or state statutory
law or regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of the
Company), insofar as such loss, claim, damage, liability or expense (or actions
in respect thereof as contemplated below) arises out of or is based (i) upon any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement, or any amendment thereto, including any information
deemed to be a part thereof pursuant to Rule 430A or Rule 434 under the 1933
Act, or the omission or alleged omission therefrom of a material fact required
to be stated therein or necessary to make the statements therein not misleading;
or (ii) upon any untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto), or the omission or alleged omission therefrom of a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; or (iii) in whole or
in part upon any inaccuracy in the representations and warranties of the Company
contained herein; or (iv) in whole or in part upon any failure of the Company to
perform its obligations hereunder or under law; or (v) any act or failure to act
or any alleged act or failure to act by the Underwriter in connection with, or
relating in any manner to, the Common Stock or the offerings contemplated
hereby, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon any matter covered by
clause (i) or (ii) above, provided that the Company shall not be liable under
this clause (v) to the extent that a court of competent jurisdiction shall have
determined by a final judgment that such loss, claim, damage, liability or
action resulted directly from any such acts or failures to act undertaken or
omitted to be taken by the Underwriter


                                       29
<PAGE>   31
through its bad faith, gross negligence or willful misconduct; and to reimburse
the Underwriter and each such controlling person for any and all expenses
(including the fees and disbursements of counsel chosen by the Underwriter) as
such expenses are reasonably incurred by the Underwriter or such controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action; provided,
however, that the foregoing indemnity agreement shall not apply to any loss,
claim, damage, liability or expense to the extent, but only to the extent,
arising out of or based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in reliance upon and in conformity with
written information furnished to the Company by the Underwriter expressly for
use in the Registration Statement, any preliminary prospectus or the Prospectus
(or any amendment or supplement thereto); and provided, further, that with
respect to any preliminary prospectus, the foregoing indemnity agreement shall
not inure to the benefit of the Underwriter from whom the person asserting any
loss, claim, damage, liability or expense purchased Purchase Shares, or any
person controlling the Underwriter, if copies of the Prospectus were timely
delivered to the Underwriter pursuant to Section 5(d) and a copy of the
Prospectus (as then amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) was not sent or given by or on behalf of
the Underwriter to such person, if required by law so to have been delivered, at
or prior to the written confirmation of the sale of the Purchase Shares to such
person, and if the Prospectus (as so amended or supplemented) would have cured
the defect giving rise to such loss, claim, damage, liability or expense. The
indemnity agreement set forth in this Section 10 shall be in addition to any
liabilities that the Company may otherwise have.

          (b) Indemnification of the Company, its Directors and Officers. The
Underwriter agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers who signed the Registration Statement and each
person, if any, who controls the Company within the meaning of the 1933 Act or
the 1934 Act, against any loss, claim, damage, liability or expense, as
incurred, to which the Company, or any such director, officer or controlling
person may become subject, under the 1933 Act, the 1934 Act, or other federal or
state statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of the Underwriter), insofar as such loss, claim, damage, liability or
expense (or actions in respect thereof as contemplated below) arises out of or
is based upon any untrue or alleged untrue statement of a material fact
contained in the Registration Statement, any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto), or arises out of or is
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the


                                       30
<PAGE>   32
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in the Registration
Statement, any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto), in reliance upon and in conformity with written information
furnished to the Company by the Underwriter expressly for use therein; and to
reimburse the Company, or any such director, officer or controlling person for
any and all expenses (including the fees and disbursements of counsel chosen by
any such person) as such expenses are reasonably incurred by the Company, or any
such director, officer or controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action. The indemnity agreement set forth in this Section
10 shall be in addition to any liabilities that the Underwriter may otherwise
have.

          (c) Notifications and Other Indemnification Procedures. Promptly after
receipt by an indemnified party under this Section 10 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 10,
notify the indemnifying party in writing of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party for contribution or
otherwise than under the indemnity agreement contained in this Section 10 or to
the extent it is not prejudiced as a proximate result of such failure. In case
any such action is brought against any indemnified party and such indemnified
party seeks or intends to seek indemnity from an indemnifying party, the
indemnifying party will be entitled to participate in, and, to the extent that
it shall elect, jointly with all other indemnifying parties similarly notified,
by written notice delivered to the indemnified party promptly after receiving
the aforesaid notice from such indemnified party, to assume the defense thereof
with counsel reasonably satisfactory to such indemnified party; provided,
however, if the defendants in any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that a conflict may arise between the positions of the indemnifying
party and the indemnified party in conducting the defense of any such action or
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel reasonably acceptable to the indemnifying party to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval by the
indemnified party of counsel, the indemnifying party will not be liable to such
indemnified party under this Section 10 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the


                                       31
<PAGE>   33
defense thereof unless (i) the indemnified party shall have employed separate
counsel in accordance with the proviso to the next preceding sentence (it being
understood, however, that the indemnifying party shall not be liable for the
expenses of more than one separate counsel (together with local counsel),
approved by the indemnifying party, or (ii) the indemnifying party shall not
have employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action, in each of which cases the fees and expenses of counsel shall be at the
expense of the indemnifying party.

          (d) Settlements. The indemnifying party under this Section 10 shall
not be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by Section
10(c) hereof, the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 60 days after receipt by such indemnifying
party of the aforesaid request and (ii) such indemnifying party shall not have
reimbursed the indemnified party in accordance with such request prior to the
date of such settlement. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement, compromise or consent
to the entry of judgment in any pending or threatened action, suit or proceeding
in respect of which any indemnified party is or could have been a party and
indemnity was or could have been sought hereunder by such indemnified party,
unless such settlement, compromise or consent includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such action, suit or proceeding.

         SECTION 11.  Contribution.

         If the indemnification provided for in Section 10 is for any reason
held to be unavailable to or otherwise insufficient to hold harmless an
indemnified party in respect of any losses, claims, damages, liabilities or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount paid or payable by such indemnified party, as incurred, as
a result of any losses, claims, damages, liabilities or expenses referred to
therein (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company, on the one hand, and the Underwriter, on the
other hand, from the offering of the Purchase Shares pursuant to this Agreement
or (ii) if the allocation provided by


                                       32
<PAGE>   34
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 Company, on the one hand, and the
Underwriter, on the other hand, in connection with the statements or omissions
or inaccuracies in the representations and warranties herein which resulted in
such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative benefits received by the
Company, on the one hand, and the Underwriter, on the other hand, in connection
with the offering of the Common Stock pursuant to this Agreement shall be deemed
to be in the same respective proportions as the total net proceeds from the
offering of the Purchase Shares pursuant to this Agreement (before deducting
expenses) received by the Company, and the total Underwriting Commission
received by the Underwriter, bear to the Aggregate Public Offering Price. The
relative fault of the Company, on the one hand, and the Underwriter, on the
other hand, shall be determined by reference to, among other things, whether any
such untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact or any such inaccurate or alleged
inaccurate representation or warranty relates to information supplied by the
Company, on the one hand, or the Underwriter, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

         The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 10, any legal or other
fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in
Section 10 with respect to notice of commencement of any action shall apply if a
claim for contribution is to be made under this Section 11; provided, however,
that no additional notice shall be required with respect to any action for which
notice has been given under Section 10 for purposes of indemnification.

         The Company and the Underwriter agree that it would not be just and
equitable if contribution pursuant to this Section 11 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in this Section 11.

         Notwithstanding the provisions of this Section 11, the Underwriter
shall not be required to contribute any amount in excess of the Underwriting
Commissions received by the Underwriter in connection with the Purchase Shares
underwritten by it and distributed to the public. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 11, each officer and employee of


                                       33
<PAGE>   35
the Underwriter and each person, if any, who controls the Underwriter within the
meaning of the 1933 Act and the Exchange Act shall have the same rights to
contribution as the Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement, and each person, if any,
who controls the Company with the meaning of the 1933 Act and the 1934 Act shall
have the same rights to contribution as the Company.

         SECTION 12.  Termination of this Forward Underwriting Agreement.

          (a) Execution of Terms Agreement. If at any time the parties enter
into a firm commitment underwriting agreement, with respect to Purchase Shares
(whether evidenced by a written agreement substantially in the form of a Terms
Agreement (as defined in the Underwriting Agreement between the Company and
NationsBanc Montgomery Securities, LLC attached as an exhibit to, or
incorporated by reference in, the Registration Statement) or any other form of
underwriting agreement) at an aggregate public offering price equal to the
Settlement Balance as of the date of such underwriting agreement, then this
Forward Underwriting Agreement shall terminate without any liability (except as
provided in Section 12(f)) on the part of either party, except that all
obligations of the parties with respect to any Purchase Shares purchased and
sold on any Pricing Date prior to the date of such termination shall remain in
effect.

          (b) Cross Acceleration Termination Event. Notwithstanding anything
herein to the contrary, if at any time a Senior Bank Debt Acceleration has
occurred, then this Forward Underwriting Agreement shall terminate and the
parties shall have no liability hereunder (except as provided in Section 12(f))
including any obligation of the Underwriter or the Company to pay for and
deliver, as the case may be, Purchase Shares sold on any Pricing Date prior to
the date of such Senior Bank Debt Acceleration.

          (c) Failure of Company to Sell and Deliver Purchase Shares. If the
Company shall fail to deliver to the Underwriter the Purchase Shares to be
delivered by the Company on any Purchase Date pursuant to this Forward
Underwriting Agreement (except as permitted hereby), then the Underwriter may at
its option, by written notice to the Company, terminate this Forward
Underwriting Agreement without any liability on the part of the Underwriter,
except that all obligations of the parties with respect to any Purchase Shares
purchased and sold prior to the date of such failure shall remain in effect.

          (d) The obligations of the Underwriter to purchase and pay for
Purchase Shares on any Purchase Date may be terminated by the Underwriter by

                       FORM OF OPINION OF COMPANY COUNSEL


         Opinion of Company Counsel to be delivered pursuant to Section 4(a) of
the Forward Underwriting Agreement shall be to the effect that:

                  (i) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware.

                  (ii) The Company is duly qualified as a foreign corporation
         and is in good standing under the laws of each other jurisdiction where
         its ownership, lease, licensing or operation of property or the conduct
         of business requires such qualification, other than in such
         jurisdiction or jurisdictions where the failure to be so qualified and
         be in good standing could not reasonably be expected to result in a
         Material Adverse Change.

                  (iii) The Company has all corporate power and authority and
         the legal right to (x) own, lease and operate its properties, (y)
         conduct the business in which it is currently engaged and (z) enter
         into, and perform its obligations under, or as contemplated under, the
         Forward Underwriting Agreement and consummate the transactions
         contemplated thereby.

                  (iv) Neither the Company nor any of its Material Subsidiaries
         is in violation of its charter or by-laws or is in default or, with the
         giving of notice or lapse of time, would be in default ("DEFAULT")
         under any indenture, mortgage, loan or credit agreement, note,
         contract, franchise, lease or other instrument to which the Company or
         any of its Material Subsidiaries is a party or by which it or any of
         them may be bound, or to which any of the property or assets of the
         Company or any of its Material Subsidiaries is subject (each, an
         "EXISTING INSTRUMENT"), except for such Defaults as could not,
         individually or in the aggregate, reasonably be expected to result in a
         Material Adverse Change. The execution, delivery and performance by the
         Company of this Forward Underwriting Agreement, the consummation of the
         transactions herein contemplated and the compliance by the Company with
         its obligations hereunder do not and will not result in any violation
         of the provisions of the Certificate of Incorporation or By-Laws or
         other constitutive documents of the Company or any Material Subsidiary,
         do not and will not conflict with or constitute a breach of, Default or
         a Debt Repayment Trigger Event under, or result in the creation or
         imposition of any lien, charge or encumbrance upon any


                                       A-1
<PAGE>   42
         assets, properties or operations of the Company or any of its Material
         Subsidiaries pursuant to, or require the consent of any other party to,
         any Existing Instrument, except for such conflicts, breaches, Defaults,
         liens (other than liens created by or contemplated in the Credit
         Agreement as in effect of the date hereof), charges or encumbrances or
         failure to obtain consent as would not, individually or in the
         aggregate, result in a Material Adverse Change and will not result in
         any violation of any applicable law or statute or any order, rule,
         regulation or judgment of any court or governmental agency or
         governmental body having jurisdiction over the Company or any of its
         Material Subsidiaries or any of their respective assets, properties or
         operations the result of which could be a Material Adverse Change.

                  (v) Each Material Subsidiary of the Company is a duly and
         validly existing entity and is in good standing under the laws of the
         jurisdiction of its incorporation, has all corporate power and
         authority to own, lease, license and operate its properties and conduct
         its business as currently conducted and is duly qualified as a foreign
         entity in good standing in each other jurisdiction, where its
         ownership, lease, license or operation of property or the conduct of
         its business requires such qualification, other than in such
         jurisdiction or jurisdictions where the failure to be so qualified and
         or be in good standing could not reasonably be expected to result in
         Material Adverse Change. All of the issued and outstanding capital
         stock of each Material 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 (other than those created by or
         contemplated in the Credit Agreement as on November 12, 1998),
         encumbrance or claim, to the best of such counsel's knowledge. None of
         the outstanding shares of capital stock of any Material Subsidiary was
         issued in violation of preemptive or other similar rights of any
         securityholder of such Material Subsidiary.

                  (vi) (A) The authorized, issued and outstanding capital stock
         of the Company is set forth in the Prospectus under the caption
         "Capitalization" (other than for subsequent issuances, if any, pursuant
         to employee benefit plans described in the Prospectus or upon exercise
         of outstanding options or warrants described in the Prospectus). (B)
         Such shares of capital stock have been duly authorized and validly
         issued by the Company and are fully paid and non-assessable and, to the
         best of such counsel's knowledge, have been issued in compliance with
         federal and state securities laws. (C) The Common Stock (including the
         Purchase Shares) conforms in all material respects to the description
         thereof


                                       A-2
<PAGE>   43
         contained in the Prospectus. (D) None of the outstanding shares of
         Common Stock was issued in violation of preemptive rights, rights of
         first refusal or other similar rights to subscribe for or purchase
         securities of the Company. (E) No stockholder of the Company or any
         other person has any preemptive right, right of first refusal or other
         rights to subscribe for or purchase, securities of the Company (except
         for any such rights granted pursuant to the Credit Agreement as in
         effect on November 12, 1998) arising (i) by operation of the
         Certificate of Incorporation or By-Laws of the Company or the General
         Corporation Law of the State of Delaware or (ii) to the best of such
         counsel's knowledge, otherwise.

                  (vii) No holder of the Common Stock is or will be subject to
         personal liability by reason of being such a holder. The form of
         certificate used to evidence the Purchase Shares is in due and proper
         form and complies with all applicable requirements of the charter and
         By-Laws of the Company and the General Corporation Law of the State of
         Delaware.

                  (viii) The Company meets the requirements for use of Form S-3
         under the 1933 Act. The Registration Statement (including any Rule
         462(b) Registration Statement, if any) has been declared effective by
         the Commission under the 1933 Act. To the best knowledge of such
         counsel, the Company has complied to the Commission's satisfaction with
         all requests of the Commission for additional or supplemental
         information. No stop order suspending the effectiveness of the
         Registration Statement is in effect and no proceedings for such purpose
         have been instituted or are pending or, to the best of such counsel's
         knowledge are contemplated or threatened by the Commission. Based on
         the advice of the Division of Corporation Finance of the Commission,
         any required filing of the Prospectus and any supplement thereto
         pursuant to Rule 424(b) under the 1933 Act has been made in the manner
         and within the time period required by such Rule 424(b).

                  (ix) The documents incorporated or deemed to be incorporated
         by reference in the Registration Statement and the Prospectus, at the
         time they were filed with the Commission, complied in all material
         respects with the requirements of the 1934 Act and the 1934 Act
         Regulations.

                  (x) To the best knowledge of such counsel, there are no
         actions, suits, proceedings, inquiries or investigations before or
         brought by any legal or governmental agency or body now pending or, to
         the best of such counsel's knowledge, threatened against or affecting
         the Company or any of its Material Subsidiaries which are required to
         be disclosed in the


                                       A-3
<PAGE>   44
         Registration Statement and the Prospectus, other than those disclosed
         therein.

                  (xi) To the best knowledge of such counsel, there are no
         Existing Instruments required to be described or referred to in the
         Registration Statement or the Prospectus or to be filed as exhibits
         thereto other than those described or referred to therein or filed or
         incorporated by reference as exhibits thereto; and the descriptions
         thereof and references thereto are correct in all material respects.

                  (xii) No consent, approval, authorization, order registration
         qualification, of or with filing any court or governmental agency or
         body having jurisdiction over the Company or any of its Material
         Subsidiaries or any of their respective properties is required for the
         due authorization, execution and delivery by the Company of, and the
         compliance by the Company with, all the terms of this Forward
         Underwriting Agreement and the consummation by the Company of the
         transactions contemplated thereby except such as have been obtained or
         made by the Company, as may be required by the securities or Blue Sky
         laws of the various States in connection with the offer and sale of the
         Purchase Shares or where the failure to obtain such consent, approval,
         authorization, order, registration, qualification, or make such filing
         will not adversely affect such authorization, execution or delivery of
         the Forward Underwriting Agreement, the compliance with the terms
         thereof or the consummation by the Company of the transactions
         contemplated hereby.

                  (xiii) 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, or development that could reasonably be expected to result in a
         material adverse change in the condition, financial or otherwise, in or
         affecting the earnings, business, operations, financial position or
         prospects, whether or not arising from transactions in the ordinary
         course of business, of the Company and its subsidiaries, considered as
         one entity, (B) there have been no transactions entered into by the
         Company or any of its Material Subsidiaries, other than those arising
         in the ordinary course of business, which are, individually or in the
         aggregate, material with respect to the Company and its subsidiaries,
         considered as one enterprise and (C) except for regular dividends on
         the Company's Common Stock or preferred stock (which dividends include
         amounts, sometimes called "dividend equivalents," paid under the
         Company's employment benefit compensation plans on the Common Stock
         grants (whether options, restricted stock or other) under such plans,
         but only to the extent such amounts do not exceed the amounts of
         ordinary


                                       A-4
<PAGE>   45
         cash dividends that would be payable were such Common Stock grants
         treated as Common Stock) or the applicable charter document or
         supplement thereto, respectively, there has been no dividend or
         distribution of any kind declared, paid or made by the Company on any
         class of its capital stock.

                  (xiv) There are no persons with registration or other similar
         rights to have any equity or debt securities registered for sale under
         the Registration Statement, except for such rights as have been duly
         waived.

                  (xv) The statements (A) in the Prospectus under the caption
         (or analagous caption) "Business-Litigation", insofar as such
         statements constitute matters of law, summaries of legal matters, the
         Company's charter or By-Law provisions, documents or legal proceedings,
         or legal conclusions, has been reviewed by such counsel and fairly
         present and summarize, in all material respects, the matters referred
         to therein.

         In addition, such counsel shall state that he has participated in
conferences with officers and other representatives of the Company,
representatives of the independent public or certified public accountants for
the Company and with representatives of the Underwriter at which the contents of
the Registration Statement and the Prospectus, and any supplements or amendments
thereto, and related matters were discussed and, although such counsel is not
passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectus (other than as specified above), and any supplements
or amendments thereto, on the basis of the foregoing, nothing has come to his
attention which would lead him to believe that either the Registration Statement
or any amendments thereto, at the time the Registration Statement or such
amendments became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus, as of its
date or as of the date of such opinion contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading (it being understood that such counsel need express no
belief as to the financial statements or schedules or other financial or
statistical data derived therefrom, included or incorporated by reference in the
Registration Statement or the Prospectus or any amendments or supplements

and specified in such opinion, upon the opinion (which shall be dated the date
of such opinion, shall be satisfactory in form and substance to the Underwriter,
shall expressly state that the Underwriter may rely on such opinion as if it
were addressed to the Underwriter and shall be furnished to the Underwriter) of
other counsel of good standing whom he believes to be reliable and who are
satisfactory to the Underwriter; provided, however, that such counsel shall
further state that he believes that he and the Underwriter are justified in
relying upon such opinion of other counsel, and (B) as to matters of fact, to
the extent they deem proper, on certificates of responsible officers of the
Company and public officials.

                FORM OF OPINION OF SPECIAL COUNSEL TO THE COMPANY


         Opinion of Special Counsel to the Company to be delivered pursuant to
Section 4(a) of the Forward Underwriting Agreement shall be to the effect that:

                  (i) The Forward Underwriting Agreement has been duly
         authorized, executed and delivered by, and is a valid and binding
         agreement of, the Company, enforceable in accordance with its terms,
         except as rights to indemnification thereunder may be limited by
         applicable law and except as the enforcement thereof may be limited by
         bankruptcy, insolvency, reorganization, moratorium or other laws of
         general application relating to or affecting the enforcement of
         creditors' rights or by general equitable principles (except that the
         opinion to be delivered on the date hereof may state that they are
         subject to ratification of this Agreement and of actions to be taken by
         the Company in connection therewith by the Board of Directors of the
         Company).

                  (ii) The Purchase Shares to be purchased by the Underwriter
         from the Company have been duly authorized for issuance and sale
         pursuant to the Forward Underwriting Agreement (except that the opinion
         to be delivered on the date hereof may state that they are subject to
         ratification of this Agreement and of actions to be taken by the
         Company in connection therewith by the Board of Directors of the
         Company) and, when issued and delivered by the Company pursuant to the
         Forward Underwriting Agreement against payment of the consideration set
         forth therein, will be validly issued, fully paid and non-assessable.

                  (iii) The Company meets the requirements for use of Form S-3
         under the 1933 Act. The Registration Statement (including any Rule
         462(b) Registration Statement, if any) has been declared effective by
         the Commission under the 1933 Act. To the best knowledge of such
         counsel, the Company has complied to the Commission's satisfaction with
         all requests of the Commission for additional or supplemental
         information. No stop order suspending the effectiveness of the
         Registration Statement is in effect and no proceedings for such purpose
         have been instituted or are pending or, to the best of such counsel's
         knowledge are contemplated or threatened by the Commission. To the
         extent related to the offer and sale of Purchase Shares, each required
         filing, if any, of the Prospectus and any supplement thereto pursuant
         to Rule 424(b) under the 1933 Act has been


                                       B-1
<PAGE>   48
         made in the manner and within the time period required by such Rule
         424(b).


                  (iv) Based on advice from the Division of Corporate Finance of
         the Commission, the Registration Statement, the Prospectus therein and
         each amendment or supplement to the Registration Statement and the
         Prospectus as of its effective or issue date, as applicable, (other
         than the financial statements and supporting schedules included or
         incorporated by reference therein or in exhibits to or excluded from
         the Registration Statement, as to which no opinion need be expressed)
         comply as to form in all material respects with the applicable
         requirements of the 1933 Act and the 1933 Act Regulations.

                  (v) The statements (A) in the Prospectus under the captions
         "Risk Factors--[___]," "Description of Capital Stock," "Management's
         Discussion and Analysis and Results of Operations--Liquidity," "Certain
         Relationships and Related Transactions," "Shares Eligible for Future
         Sale," "Certain United States Income Tax Considerations" and
         "Underwriting" or analogous captions and (B) in Item 14 and Item 15] of
         the Registration Statement, insofar as such statements constitute
         matters of law, summaries of legal matters, the Company's charter or
         By-Law provisions, documents or legal proceedings, or legal
         conclusions, has been reviewed by such counsel and fairly present and
         summarize, in all material respects, the matters referred to therein.

                  (vi) The Company is not, and upon the issuance and sale of the
         Purchase Shares as herein contemplated and the application of the net
         proceeds therefrom as described in the Prospectus will not be, an
         "investment company" within the meaning of the Investment Company Act
         of 1940, as amended.

         In addition, such counsel shall state that they have participated in
conferences with officers and other representatives of the Company,
representatives of the independent public or certified public accountants for
the Company and with representatives of the Underwriter at which the contents of
the Registration Statement and the Prospectus, and any supplements or amendments
thereto, and related matters were discussed and, although such counsel is not
passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectus (other than as specified above), and any supplements
or amendments thereto, on the basis of the foregoing, nothing has come to their
attention which would lead them to believe that either the Registration
Statement


                                       B-2
<PAGE>   49
or any amendments thereto, at the time the Registration Statement or such
amendments became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus, as of its
date or as of the date of such opinion contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading (it being understood that such counsel need express no
belief as to the financial statements or schedules or other financial or
statistical data derived therefrom, included or incorporated by reference in the
Registration Statement or the Prospectus or any amendments or supplements
thereto).

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the General
Corporation Law of the State of Delaware, the State of New York or the federal
law of the United States, to the extent they deem proper and specified in such
opinion, upon the opinion (which shall be dated the date of such opinion, shall
be satisfactory in form and substance to the Underwriter, shall expressly state
that the Underwriter may rely on such opinion as if it were addressed to the
Underwriter and shall be furnished to the Underwriter) of other counsel of good
standing whom they believe to be reliable and who are satisfactory to the
Underwriter; provided, however, that such counsel shall further state that they
believe that they and the Underwriter are justified in relying upon such opinion
of other counsel, and (B) as to matters of fact, to the extent they deem proper,
on certificates of responsible officers of the Company and public officials.

                                    AGREEMENT
                                VINCENT J. CORBO

Purpose and Term of Agreement:

In anticipation of the consummation of the BetzDearborn transaction, this is to
confirm Vincent J. Corbo's (VJC) agreement to remain as an employee of Hercules
Incorporated as President and Chief Operating Officer, or any other position
which may be mutually agreed upon, from July 29, 1998 through January 1, 2001.
During this term, the following conditions will apply.

Position/Title:

President and Chief Operating Officer of Hercules Incorporated and a member of
Hercules Incorporated Board of Directors.

Base Salary:

Effective August 1, 1998, his annualized base salary will be increased by
$100,000 to $550,000. At closing, his base salary will be set at no less than
75% of the highest annualized rate then in effect for the Chief Executive
Officer or co-Chief Executive Officer(s). Until this agreement expires his
annualized base salary will be increased as required to ensure that his rate is
no less than 75% of the highest annualized rate in effect for the Chief
Executive Officer or co-Chief Executive Officer(s).

Incentive Payments:

If VJC remains as an active employee of Hercules Incorporated as described above
through January 1, 2001, the following incentive payments will be provided:

         A.  Restricted Stock

         A grant of Restricted Stock Units with a value of $2,000,000 on the
         grant date and at the grant price hereinafter defined. The grant price
         used to determine the actual number of units will be the closing price
         of one share of Hercules Common Stock on August 4, 1998, as reported on
         the Composite Tape for New York Stock Exchange Listed Companies and
         published in the Eastern Edition of The Wall Street Journal. Such units
         will accrue dividend equivalents and interest, payable at vesting.

         These units will vest to you on January 1, 2001, and be payable, at
         your option, in shares of Hercules Incorporated Common Stock or cash,
         net of applicable taxes.
<PAGE>   2
         B.  Cash

         If still employed on January 1, 2001 as stipulated above, a cash award
         of $1,000,000 will be earned and will be paid, net of applicable taxes.

Change of Control:

In the event of a solicited or unsolicited change of control of Hercules
Incorporated as defined in your Employment Contract dated June 29, 1995, the
provisions for payment of the following elements of this Agreement will be
applicable:

         -     Restricted Stock Incentive
         -     Cash Incentive

Where provisions may be made to provide for payment of Employment Contracts for
certain HPC individuals as a result of the Bluenose transaction, this
opportunity will not apply to you.

Pension Adjustments:

If still employed on January 1, 2001 as stipulated above, you will earn the
right to the following enhancements of pension benefit credits when you elect to
retire:

         1.       You shall be given credit for three additional years of
                  service for purposes of calculating pension benefits.

         2.       You shall be given credit for the number of additional years
                  of age for purposes of calculating pension benefits to the
                  extent needed to provide that you had attained age 60.

No additional credit for years of age shall be accounted for beyond the actual
attainment of age 60 if you remain an active employee of Hercules Incorporated,
but you will be eligible to earn additional years of service for purposes of
calculating pension benefits. However, under no circumstances will service
credit be applied beyond your attainment of age 65.

Mega Grant Stock Option Agreements:

         1.       For the PASO awards made under the LTICP on October 29, 1996,
                  it will be determined that all minimum vesting date(s)
                  requirements will be satisfied if you are still employed on
                  January 1, 2001.

         2.       For the PASO awards made under the LTICP on February 7, 1997,
                  it will be determined that all minimum vesting date(s)
                  requirements will be satisfied if you are still employed on
                  January 1, 2001.

The provisions for Accelerated Vesting as provided for in the Award Commitment
notices will remain applicable.


                                       2
<PAGE>   3
At the times when William R. Cook receives Performance Accelerated Stock Options
(PASO's), otherwise known as Mega Grants, per the terms of his Employment
Agreement, then VJC will receive PASO's, otherwise known as Mega Grants, such
that the total PASO's, including those awarded on October 29, 1996 (300,000
shares), and February 7, 1997 (150,000 shares), are 75% of the total number of
shares granted to Mr. Cook. Terms and conditions for vesting will be the same as
applied for Mr. Cook under the conditions of the LTICP. Provision for
acceleration of vesting under special circumstances as described in this
agreement will not apply to these extra awards.

Matching Grant:

For the record, under the terms of the Matching Grant included in your
confirmation letter of February 28, 1997, the Restricted Stock Units and
Restricted Stock, with accrued dividend equivalents and interest, will vest to
you on May 1, 2000, and all other terms of the letter will apply.

At the time when William R. Cook has the opportunity to participate in the
Hercules Matching Grant Program, VJC will have the opportunity to extend his
participation in the Program such that the multiplier for determining the
matching Restricted Stock is 75% of the multiplier in effect for Mr. Cook. Terms
and conditions for vesting of Restricted Stock will be the same as applied to
Mr. Cook under the conditions of the LTICP. Provisions for acceleration of
vesting under special circumstances as described in this agreement will not
apply to this extra grant feature.

Special Circumstances:

If because of extraordinary events VJC decides that it is in his best interests
and the best interests of HPC to resign with at least 60 days advance notice
prior to January 1, 2001, and with the agreement of the Compensation Committee
of the Board of Directors, then certain considerations will be provided:

         1.       At the time of the effective date of resignation you will be
                  paid in cash an amount equal to two (2) times the base annual
                  salary in effect at that time, less applicable taxes.

         2.       At the time of the effective date of resignation you will earn
                  the right to the enhancements of pension benefit credits when
                  you elect to retire as set forth in the Pension Adjustments
                  section above.

Accelerated vesting for the Mega Grants and vesting of Restricted Stock under
the Matching Grants will be determined by the terms of the Long Term Incentive
Plan, or any special action which may be authorized by the Compensation
Committee of the Board of Directors


                                       3
<PAGE>   4
Perquisites:

In determining the perquisites which will be provided through January 1, 2001,
you will have the option to elect whatever benefits you choose, as would be
reasonably made available to a senior HPC executive, up to a dollar value that
is 75% of the amount provided for perquisites for the Chief Executive Officer or
co-Chief Executive Officer(s). These perquisites may include such items as
automobile, country club memberships, eating club memberships, etc. but
specifically excludes the use of company-owned or leased aircraft for business
or personal travel. Any tax liabilities for perquisite payments will be
grossed-up.

Director's Charitable Award Program:

If VJC remains an active employee of Hercules Incorporated as described above
through January 1, 2001, and remains as a Director of Hercules Incorporated for
the same period, then he will become fully vested in the Program.

Company-owned Leased Aircraft:

VJC will have the authority to utilize company-owned or leased aircraft for
business travel only within the continental U.S. during a calendar year (or
pro-rata portion thereof) up to a value of $200,000. Rates for aircraft
utilization will be actual charges for leased equipment and for the calculated
effective operating rate for company-owned aircraft.

Death:

If, prior to the expiration of this agreement, VJC dies or becomes permanently
and totally disabled as determined under the provisions of the Long Term
Disability Plan, then his designated beneficiaries will receive the greater of
the base salary and pension considerations contained in the Special
Circumstances section, or the pro-rated value of the Incentive Payments and
Pension Adjustments set forth above.

                              EMPLOYMENT AGREEMENT

         THIS Employment Agreement ("Agreement") is entered into as of October
15, 1998, by and BETWEEN HERCULES INCORPORATED (the "Company"), a Delaware
corporation, and WILLIAM R. COOK ("EXECUTIVE").

                                    RECITALS

         WHEREAS, pursuant to the Agreement and Plan of Merger among Hercules
Incorporated, Water Acquisition Co. and BetzDearborn Inc. dated as of July 30,
1998 (the "Merger Agreement"), the Company has agreed to purchase all the issued
and outstanding stock of BetzDearborn Inc., a Pennsylvania Corporation;

         WHEREAS, Executive is currently employed by BetzDearborn Inc. subject
to an employment agreement dated March 20, 1998, and as amended effective as of
March 6, 1998 (the "BetzDearborn Employment Agreement");

         WHEREAS, the Company and Executive intend that Executive's transition
from employment by BetzDearborn Inc. to employment by the Company not constitute
a termination of his employment by BetzDearborn Inc. under his BetzDearborn
Employment Agreement;

         WHEREAS, the Company and Executive desire that this Agreement
constitute an assumption, cancellation of, and replacement for, his BetzDearborn
Employment Agreement in its entirety;

         WHEREAS, the Company and Executive desire that Executive provide,
following the Acquisition, employment services to the Company upon the terms and
conditions set forth below;

         NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein, the parties agree as follows.


<PAGE>   2

         1. EFFECTIVE DATE OF AGREEMENT. This Agreement constitutes an
assumption, cancellation, and replacement of the BetzDearborn Employment
Agreement in its entirety and will be effective, and Executive's employment by
the Company pursuant hereto will commence, at the Effective Time (as defined in
the Merger Agreement) on the date which includes the Effective Time (the
"Effective Date").

         2. TERM OF EMPLOYMENT. This Agreement, and Executive's employment by
the Company pursuant hereto, will be for the period commencing on the Effective
Date and continuing for the three (3) year period commencing on such date (the
"Term"), unless sooner terminated pursuant to the terms hereof. Executive agrees
that his transition from employment by BetzDearborn Inc. to employment by the
Company under this Agreement shall not constitute, and shall not be treated as,
a termination of his employment under his BetzDearborn Employment Agreement.

         3. DUTIES OF EXECUTIVE. During the Term, Executive will be employed as
the Company's Co-Chief Executive Officer and shall (pursuant to and subject to
the Merger Agreement) serve as the Vice-Chairman of the Company's Board of
Directors (the "Board of Directors"). Executive will have and fulfil1 (i) all of
the duties and responsibilities ordinarily associated with such status as
Co-Chief Executive Officer at an organization comparable to the Company and (ii)
any duties and responsibilities established for the Company's Co-Chief Executive
Officer in the Company's charter or bylaws or other organizational documents or
by the Board of Directors that are consistent with his position and status as
Co-Chief Executive Officer. The Board of Directors will have the right to assign
to Executive such other or additional duties and responsibilities, or reduce
Executive's duties and responsibilities (provided such reductions do not
materially diminish his position, authority or responsibilities at the


<PAGE>   3

Company) as the Board of Directors deems in the Company's best interest, and
Executive will fulfill such duties and responsibilities as directed by the Board
of Directors. Executive will devote substantially all of his working time,
attention, and energy to the Company's business and will not during the term of
this Agreement engage in any substantial outside business or other activity
unrelated to serving the Company's interest, unless he receives prior approval
for such activities from the Board of Directors; provided, however, that
Executive may continue to occupy, without Board approval, a seat on the Board of
Directors of Teleflex Corporation. Executive will fulfill his duties and
responsibilities as described in this Paragraph 3 in a reasonable and
appropriate manner in light of the Company's policies and practices as
established by the Board of Directors and the laws and regulations and policies
which apply to the Company's operation and administration. Executive agrees
(and, under Section 6(c)(4) of the BetzDearborn Employment Agreement consents
to) perform his duties and responsibilities under this Agreement primarily at
the Company's headquarters in Wilmington, Delaware and to commute to such
headquarters to perform his duties and responsibilities at such headquarters.

         4. BASE SALARY. Subject to the provisions of Paragraph 6, the Company
will pay Executive a base salary ("Base Salary"), which will be paid in
accordance with the Company's standard payroll practices and policies as in
effect from time to time for salaried employees, as follows:

                  (a) Beginning on the Effective Date, Executive's Base Salary
         will be $700,000 per year, less applicable withholding;

                  (b) Beginning on the nine month anniversary of the Effective
         Date, Executive's Base Salary will be increased to $750,000 per year,
         less applicable withholding; and
<PAGE>   4

          (c) Beginning on the eighteen month anniversary of the Effective Date,
Executive will be paid a Base Salary, less applicable withholding, that the
Board of Directors determines is consistent with the competitive market value of
the duties performed by Executive under Paragraph 3 of this Agreement; provided,
however, that Executive's Base Salary shall in no event be less than $750,000
per year, less applicable withholding. In reaching its determination, the Board
of Directors will take into account comparative data concerning the salaries of
individuals with similar duties and responsibilities in the industry in which
the Company operates. Such comparative data will be obtained from one, or more
than one, nationally recognized compensation consulting firms selected by the
Board of Directors.

5.       BENEFITS.

          (a) MICP. Executive shall be eligible to participate in the Company's
Management Incentive Compensation Plan ("MICP") in 1998, 1999, 2000 and 2001
subject to all the terms and conditions in such plan except that (i) his target
for each such year shall be set under this Agreement and (ii) if Executive's
employment terminates for any reason other than by the Company for Good Cause
(as defined in Paragraph 6(a)(3)) after 1998, he shall be treated under Section
14.1 of the MICP as if he had retired. A copy of the MICP as in effect as of the
Effective Date is attached to this Agreement as Exhibit A. Executive's target
under the MICP for 1998 shall be (i) $490,000, pro rated for the period from the
Effective Date through December 31, 1998 but reduced for the portion of any
bonus payable under any BetzDearborn Inc. bonus program which is attributable to
such proration period; (ii) $490,000 for 1999; (iii) $600,000 for 2000; and (iv)
90% of his Base Salary in effect on January 1, 2001 for 2001; provided, however,
<PAGE>   5

that if Executive terminates employment on or after the expiration of the Term
but prior to December 31, 2001, payments made to him under MICP for 2001 shall
be pro rated.

          (b)     Restricted Stock.

                   (1) Sign Up Restricted Stock Grant. Executive shall receive a
         restricted stock grant under the Company's Long Term Incentive
         Compensation Plan ("LTICP") equal to the number of whole shares of the
         Company's common stock determined by dividing (i) $2,967,000 by (ii)
         the average closing price for a share of the Company's common stock as
         reported in the Eastern Edition of The Wall Street Journal for the five
         (5) consecutive trading days before the Effective Date (the "Sign Up
         Restricted Stock Grant"). The Company shall pay to Executive cash in
         lieu of a fractional share of common stock based on such average
         closing price.

                  (2) Vesting. One third of the number of shares subject to the
         Sign Up Restricted Stock Grant shall have a Restricted Period (as
         defined under the LTICP) ending on the eight month anniversary of the
         Effective Date, one third of the number of such shares shall have a
         Restricted Period ending on the sixteen month anniversary of the
         Effective Date, and the remaining one third shall have a Restricted
         Period ending on the twenty four month anniversary of the Effective
         Date. Executive in addition will vest 100% in the Sign Up Restricted
         Stock Grant (without regard to the Restricted Period) upon (i) the date
         of his termination of employment (A) by the Company other than for Good
         Cause or (B) by Executive for Good Reason; (ii) the date the
         Compensation Committee of the Board of Directors approves Executive's
         request to retire at any time following the eight month anniversary of
         the Effective Date on account of an unforeseen financial emergency or
         other family circumstances which Executive believes will render him no
         longer able to perform the essential 


<PAGE>   6

     functions of his job, which approval shall not be withheld if the
     Compensation Committee determines that such belief on the part of Executive
     is reasonable; (iii) the death of Executive; or (iv) the date that the
     Board of Directors reasonably determines that because of a mental or
     physical impairment Executive has been unable for a period of at least six
     (6) consecutive months to perform the essential functions of his job with
     or without reasonable accommodation (a "Disability"). A retirement which is
     approved under Paragraph 5(b)(2)(ii) shall be treated under this Agreement
     as a termination by Executive without Good Reason under Paragraph 6(b)(2)
     except as provided in this Paragraph 5(b)(2).

          (3) Supplemental Grants. The Company shall make a grant of
     nonforfeitable, nonrestricted stock to Executive as of the date, or on each
     date, that Executive's interest in all or a part of the Sign Up Restricted
     Stock Grant vests (the "Vest Date") under Paragraph 5(b)(2) (a
     "Supplemental Grant") if (i) the total Vested Date Value of the number of
     shares of the Company's common stock subject to the Sign Up Restricted
     Stock Grant in which Executive's interest vests on the Vest Date is less
     than (ii) the total value attributable to such shares as determined under
     Paragraph 5(b)(I)(ii) on the date of the grant of the Sign Up Restricted
     Stock Grant (as adjusted by the Company to account for any stock splits,
     stock dividends or other changes in the Company's capital structure). Such
     Supplemental Grant, or each such Supplemental Grant, shall equal the number
     of whole shares of the Company's common stock determined by dividing the
     difference between the value under this Paragraph 5(b)(3)(i) and
     5(b)(3)(ii) by the Vest Date Value of a share of the Company's common stock
     on the Vest Date. The term Vest Date Value under this Paragraph 5(b)(3)
     shall mean the average closing price for a share of the Company's common
     stock as


<PAGE>   7
     reported in the Eastern Edition of The Wall Street Journal for the five (5)
     consecutive trading days ending on the Vest Date. The Company shall pay to
     Executive cash in lieu of a fractional share of common stock based on the
     Vest Date Value.

          (4) LTICP Terms. Except as provided in this Paragraph 5(b), the Sign
     Up Restricted Stock Grant shall be made subject to the same terms and
     conditions as standard restricted stock grants made under the LTICP. (c)
     Unrestricted Stock. Executive (as soon as practicable after Executive
     receives the cash from the Acquisition attributable to his BetzDearborn
     Inc. restricted stock grants and stock options) shall purchase a number of
     shares of common stock of the Company equal to (i) $1,700,000 divided by
     (ii) the average closing price of a share of the Company's common stock as
     reported in the Eastern Edition of The Wall Street Journal for the three
     trading days immediately following the Effective Date. Such purchase may be
     made from the Company or in the open market, as agreed upon between the
     Company and Executive.

          (c) Stock Ownership Guidelines. Executive shall purchase such common
stock of the Company as required to satisfy the Company's Stock Ownership
Guidelines in full within the three year period starting on the Effective Date
in accordance with the terms of such guidelines. The stock awarded under
Paragraphs 5(b) and 5(c) shall be counted towards the satisfaction of such
guidelines together with his other Company stock holdings, direct or indirect,
which are of a kind taken into account for other executives under such
guidelines.

          (d) Matching Grant Program. Executive shall have a one-time right to
elect to participate in the Company's Matching Grant Program pursuant to the
terms of such program. Such election shall be made in writing no later than 3
business days following the first date after the Effective Date that the


<PAGE>   8

Company makes a public announcement of its quarterly earnings and shall be
delivered to the Company's Vice President, Human Resources and, if Executive
makes such election by such deadline, the Company match in restricted stock
under the program will vest at the end of the Term if Executive remains employed
under this Agreement through the end of the Term. The program as currently in
effect requires the purchase of Hercules restricted stock units outright or
through salary and/or annual bonus deferral up to 65% of the present value of
four years salary in effect at the time of election. The Company will match any
purchase of Hercules restricted stock units with a grant of restricted stock
equal to two times the number of restricted stock units purchased. The Company
match of restricted stock normally is restricted for three years, but in the
case of Executive shall be restricted until the third anniversary of the
Effective Date and, in the event of voluntary resignation within that period for
any reason, including retirement, will be forfeited. The Company shall provide
such additional information to Executive regarding the program as he shall
reasonably request from the Company.

         (f) Stock Options. Executive shall be granted a "performance
accelerated stock option" under the LTICP (i) as of the Effective Date, for
500,000 shares of common stock, (ii) as of September 30, 1999, for 250,000
shares of common stock, and (iii) as of June 30, 2000, for 250,000 shares of
common stock, each as adjusted by the Company to account for stock splits, stock
dividends and other changes in the Company's capital structure. Each such grant
shall be made only if Executive is employed by the Company on the date as of
which such grant is called for under this Agreement. Each such option shall be
granted at fair market value option price on the date of grant (as determined
under the LTICP) and shall be evidenced by an agreement in substantially the
same form as the form agreement for each grant which is attached to this
Agreement as Exhibit B-I through B-3. The Compensation Committee of the Board of
Directors may, at its discretion, grant additional stock options to Executive
during the Term.

     (g) Other Benefits.

          (I) Supplemental Pension Benefit

               (A) Formula. A benefit shall be payable to, or on behalf of,
Executive under this Paragraph 5(g)(l) upon his termination of employment for
any reason. The amount of such benefit shall (subject to the other provisions of
this Paragraph 5(g)(1)) be determined under the benefit formula in effect under
the BetzDearborn Inc. Employees Retirement Plan as in effect on the Effective
Date (the "BD Plan") without regard to (i) any reduction otherwise required
under the BD Plan as a result of the application of the Section 415 Limitation
(as defined in the BD Plan) and (ii) any reduction otherwise required under the
BD Plan by reason of the compensation exclusion called for under Section
401(a)(17) of the Internal Revenue Code of 1986, as amended (the "Code").

               (B) Special Benefit Calculation Rules. Executive's benefit under
Paragraph 5(g)(l)(A) shall be calculated subject to the following special rules:

                    (i) Age. If Executive is less than 65 years old at the time
     his employment terminates, he shall be treated as if he was 65 years old.

                    (ii) Compensation.

                           (1) Any Base Salary and MICP bonus actually
paid to Executive by the Company or any successor to the Company shall be taken
into account on the same basis that such compensation would have been taken into
account if paid by BetzDearborn Inc.

                            (2) If Executive's employment with the Company
terminates before the end of the Term, the Base Salary and MICP target bonus
which would have been payable to Executive through the remainder of the Term but
for such termination of employment shall be


<PAGE>   10

taken into account as if Executive's employment had continued for the remainder
of the Term on the same basis that such compensation would have been taken into
account if actually paid by BetzDearborn Inc. over the remainder of the Term. If
Executive's employment terminates before his actual Base Salary is set under
Paragraph 4(c), his Base Salary under Paragraph 4(c) shall be treated as equal
to $750,000 and his MICP target bonuses under Paragraph 5(a)(iv) shall be
treated as equal to $675,000.

                     (iii) Service. All service actually completed by Executive
with the Company or any successor to the Company shall be treated as service
completed with BetzDearborn Inc. and, further, Executive's actual number of
years of service shall be increased by three full years.

         (C) Payment Form. Executive's benefit under this Paragraph
5(g)(l) shall be paid in accordance with the benefit payment form and timing and
joint annuitant and/or beneficiary designation rules set forth in Article V of
the BetzDearborn Inc. Pension Restoration Plan as in effect on the Effective
Date (the "BD Restoration Plan") based on the benefit payment form and timing
and joint annuitant and/or beneficiary designations made by Executive with
respect to the payment of his benefits under the BD Plan or, if the BD Plan is
merged into another plan (a "'Successor Plan"), with respect to the payment of
his benefit under such Successor Plan which is attributable to his benefit
accrued under the BD Plan.

         (D) Offset. The benefit described in Paragraph 5(g)(1)(A) shall
be offset (i) by the benefit actually payable to, or on behalf of, Executive
under the BD Plan or any successor to such plan, the BD Restoration Plan or any
successor to such plan and any defined benefit plan (as defined in Section
414(j) of the Code) maintained by the Company or any successor to the Company or
(ii) by the actuarial equivalent of the benefit payable under any such plan
described in


<PAGE>   11

Paragraph 5(g)(l)(D)(i) if the benefit paid under such plan is paid
in a form or at a time or to a person or persons different from the form or time
or person or persons described in Paragraph 5(g)(C). Any actuarial equivalent
calculations required under this Paragraph 5(g)( l )(D) shall be made in
accordance with the actuarial equivalent factors, tables and interest rate and
other assumptions in the BD Plan.

         (E) No Assignment. Neither Executive nor any other person shall have
any right whatsoever to transfer, alienate, or assign his or her right to the
benefit described in this Paragraph 5(g)(l) and attempt to do so shall be null
and void.

         (F) General Creditor Status. Neither Executive nor any other person
shall have a claim to the benefit described in this Paragraph 5(g)(l) which is
superior to the right of a claim of a general and unsecured creditor of the
Company or any successor to the Company, and neither Executive nor any other
person shall have the right to look to any assets except the general assets of
the Company or any successor to the Company for the payment of such benefit.

         (G) Rabbi Trust. The Company has established a trust under the Hercules
Incorporated Compensation Benefits Grantor Trust Agreement for Management
Employees (the "Rabbi Trust") to provide a mechanism through which the Company
can (subject to the terms of the Rabbi Trust and the conditions set forth in the
Rabbi Trust related to the funding of the Rabbi Trust) satisfy the Company's
obligation to pay certain benefits to the Company's executives, including
benefits under Hercules Incorporated Nonqualified Supplemental Retirement Plan,
and the Company as of the Effective Date shall add the Company's obligation to
pay the benefit described in this Paragraph 5(g)(l) to the list of the Company's
obligations furnished to the Trustee for the Rabbi Trust which shall (subject to

<PAGE>   12

the terms of the Rabbi Trust and the conditions set forth in the Rabbi Trust
related to the funding of the Rabbi Trust) be satisfied through the Rabbi Trust
or any successor to such Trust.

               (2) Company Automobile. Executive shall have his choice while
employed by the Company of the use of (i) an automobile comparable to that
provided to the Company's other Co-Chief Executive Officer (which currently is a
Mercedes Benz S420) or (ii) an appropriate car (such as a Lincoln Town Car) and
driver only for business use. Executive shall maintain appropriate records of
his business and personal use of an automobile and shall make such records
available to the Company to account for such use in accordance with the income
tax laws

               (3) Other Executive Benefits. The Company shall make available to
Executive the same plans, programs and benefits as the Company generally makes
available to the members of the Hercules Management Committee, as long as such
committee includes the Company's Chief Executive Officer or Co-Chief Executive
Officer or, if it does not, to the other most senior executives of the Company,
except to the extent like-kind plans, programs or benefits are otherwise
expressly called for elsewhere in this Paragraph 5.

               (4) Chief Executive Officer Perks. Executive while employed by
the Company shall have his choice of appropriate executive officer perquisites,
such as social and dining club memberships, routine physical examinations,
financial counseling, a special entertainment allowance, and a home security
system; provided, the aggregate annual value of such perquisites shall not
exceed S17,600 a calendar year (which figure shall be pro-rated for any part of
a calendar year) or such other


<PAGE>   13

figure as provided to the Company's other Co-Chief Executive Officer for such
calendar year as determined by the Company for financial reporting purposes.

               (5) Tax Protection. If the Company or the Company's accountants
determine that the payments and other benefits called for under this Agreement
or any other payments or benefits to or for the benefit of Executive either
pursuant to the Merger Agreement or from the Company after the Effective Date
will result in Executive being subject to an excise tax under Section 4999 of
the Code and/or if such an excise tax is assessed against Executive as a result
of such payments or other benefits, the Company shall make a Gross Up Payment
(as defined in this Paragraph 5(g)(5)) to or on behalf of Executive as and when
such determination(s) and assessment(s), as appropriate, are made, provided
Executive takes such action as the Company reasonably requests under the
circumstances to mitigate or challenge, or to mitigate and challenge, such tax
and the Company complies with its obligations under this Paragraph 5(g)(5). A
"Gross Up Payment" means a payment to or on behalf of Executive which shall be
sufficient to pay (i) any such excise tax in full, (ii) any federal, state and
local income tax and social security or other employment tax on the payment made
to pay Executive's excise tax as well as any additional excise tax on such
payment and (iii) any interest or penalties assessed by the Internal Revenue
Service on Executive if such interest or penalties are attributable to the
Company's failure to comply with its obligations under this Paragraph 5(g)(5) or
applicable law. Any determination under this Paragraph 5(g)(5) by the Company or
the Company's accountants shall be made in accordance with Section 280G of the
Code and any applicable related regulations (whether proposed, temporary or
final) and any related Internal Revenue Service rulings and any related case law
and, if the Company reasonably requests that


<PAGE>   14

Executive take action to mitigate or challenge, or to mitigate and challenge,
any such tax or assessment and Executive complies with such request, the Company
shall provide Executive with such information and such expert advice and
assistance from the Company's accountants, lawyers and other advisors as he may
reasonably request and shall pay for all expenses incurred in effecting such
compliance and any related fines, penalties, interest and other assessments.

         6. TERMINATION. This Agreement, and Executive's employment by the
Company hereunder, may be terminated early as follows:

         (a) By the Company.

<PAGE>   15

          each year in such period pay Executive the sum of (i) the Base Salary
          in effect under Paragraph 4 as of the date of such termination, less

          Paragraph 5(a) as of the date of such termination, less applicable
          withholding.

         withholding.

                  (C) If the Company terminates Executive's employment without

the Company or its successors in the change in control transaction of any
provision of this Agreement that continues to be applicable pursuant to this
Paragraph 6(d) shall be treated as a breach of such change in control agreement
by the Company and such successor.

         7. CONFIDENTIALITY. Executive acknowledges that during the course of
his employment with the Company he has received or will receive and has had or
will have access to Confidential Information and Trade Secrets of the Company,
including but not limited to confidential and secret business and marketing
plans, strategies, and studies, detailed customer and/or client lists and
information relating to the operations and business requirements of those
customers and/or clients, and accordingly, he is willing to enter into the
covenants contained in this Agreement in order to provide the Company with what
he considers to be reasonable protection for its interests.

          (a) Trade Secrets. Executive agrees and covenants that, both during
the term of this Agreement and after the termination of this Agreement,
Executive will hold in a fiduciary capacity for the benefit of the Company, and
will not directly or indirectly use or disclose, except as authorized by the
Company in connection with the performance of Executive's duties, any Trade
secret, as defined


<PAGE>   20

hereinafter, that Executive may have or acquire during the term of this
Agreement for so long as the such information remains a Trade Secret.

                            (1) The term "Trade Secret" as used in this
                  Agreement will mean information including, but not limited to,
                  technical or non-technical data, a formula, pattern,
                  compilation, program, device, method, technique, drawing,
                  product, system or process, design, prototype, procedure, code
                  or financial data, or a list of actual or potential customers
                  or suppliers, including without limitation, information
                  received by the Company or Executive from any client or
                  potential client of the Company, that:

                                    (A) derives economic value, actual or
                           potential, from not being generally known to, and not
                           being readily ascertainable by proper means by the
                           public or any other person who can obtain economic
                           value from its disclosure or use; and

                                    (B) is the subject of reasonable efforts by
                           the Company or the client from which the information
                           was received to maintain its secrecy or
                           confidentiality.

These rights of the Company are in addition to those rights the Company has
under the common law or applicable statute for protection of trade secrets.

                  (b) Confidential Information. In addition to the foregoing and
         not in limitation thereof, Executive agrees that, during the Term of
         this Agreement and for a term of three (3) years after termination of
         his employment, Executive will hold in a fiduciary capacity for the
         benefit of the Company and will not directly or indirectly use or
         disclose, except


<PAGE>   21

     as authorized by the Company in connection with the performance of
     Executive's duties, any confidential or proprietary information; as defined
     hereinafter, that Executive may have or acquire (whether or not developed
     or compiled by Executive and whether or not Executive has been authorized
     to have access to such confidential or proprietary information) during the
     term of this Agreement. The term "Confidential Information" as used in this
     Agreement means any secret, confidential or proprietary information of the
     Company, including information received by the Company or Executive from
     any customer or client or potential customer or client of the Company, not
     otherwise included in the definition of "Trade Secret" in Paragraph
     7(a)(l). The term "Confidential Information" does not include information
     that has become generally available to the public other than by Executive
     in violation of this Agreement or his violating any right of the customer
     or client to which such information pertains.

     8. NON-COMPETITION. The Company and Executive agree that the Company's
customer and/or client contacts and relations are established and maintained at
great expense and that Executive will, by virtue of his employment with the
Company, have unique and extensive exposure to and personal contact with the
Company's customers and/or clients and that he will be able to establish a
unique relationship with those customers and/or clients. Moreover, the Company
and Executive agree that during the course of his employment with the Company he
has received or will receive and has had or will have access to Confidential
Information and Trade Secrets of the Company, which Executive agrees would be
inevitably used or disclosed if Executive leaves the Company for employment with
a competitor of the Company. Accordingly, in order to protect the Company from
unfair competition, Executive covenants and agrees that he


<PAGE>   22

will not, while employed by the Company (including employment continuing beyond
the expiration of the Term) and continuing thereafter for the longer of (a) any
period during which Executive receives any payments under Paragraph 6(a)(2) of
this Agreement or (b) one year from the date of termination of Executive's
employment, collectively the "Non-competition Period," directly or indirectly,
(whether as owner, partner, stockholder, investor, officer, director, agent,
independent contractor, associate, employee, consultant or licensor (other than

the nonwoven or fabricated textile industry, or (f) water treatment chemicals
("Company Business") anywhere in the United States, Europe, Latin America, South
America, or Asia ("Territory"), which is the geographic area in which the
Company engages in this business and, as such, where Executive will be
performing his responsibilities under this Agreement. Executive further
covenants that during the Non-competition Period he will not own or share in the
earnings of or invest in the capital stock of any corporation, partnership,
venture or other business entity which competes with the Company in the
Territory in the Company Business ("Competitor"). Provided, however, that
Executive may passively invest in stocks, bonds or other securities of any
Competitor if:

         (a) such stock, bonds or other securities are listed on a national or
regional securities exchange or have been registered under Section 12(g) of the
Securities Exchange Act of 1934, and

          (b) Executive's investment in any class of securities does not exceed
5% of the aggregate amount of such class outstanding, as the case may be.
<PAGE>   23

         9. NON-SOLICITATION OF EMPLOYEES. Executive agrees and covenants that
during the Non-competition Period he will not, for any reason, either
individually, or as an owner, partner, employee, agent, consultant, advisor,
contractor, salesman, stockholder, investor, officer, director, or other member
of any corporation, partnership, venture or other business entity, solicit any
employee of the Company with whom Executive had material Contact during
Executive's employment with the Company to leave his or her employment with the
Company.

     10. NON-SOLICITATION OF CUSTOMERS AND/OR CLIENTS. Executive agrees and
covenants that during the Non-competition Period he will not, for any reason,

and/or client, of the Company with whom Executive had material business contact
during Executive's employment with the Company for the purpose of competing with
the Company in the Company Business.

         11. REASONABLENESS. Executive acknowledges and agrees that the
restrictions, prohibitions and covenants in Paragraphs 7, 8, 9 and 10 are
reasonable, fair and equitable in scope, terms and duration, are necessary to
protect the legitimate business interests of the Company.

         12. REFORMATION. If any of the covenants in Paragraphs 7, 8, 9 and 10
of this Agreement are determined by any court of law or equity, with
jurisdiction over this matter, to be unreasonable or unenforceable, in whole or
in part, as written, Executive hereby consents to and affirmatively requests
that said court reform the covenant or promise so as to be reasonable and
enforceable and that said court enforce the covenant or promise as reformed.
<PAGE>   24

         13. LEGAL AND EQUITABLE REMEDIES. Executive agrees that for any breach
or threatened breach of any of Paragraphs 7 through 10 of this Agreement, a

result of, his employment shall, as between the parties hereto, remain the sole
property of the Company. Upon the termination of his employment or upon the
prior demand of the Company, he shall immediately return all such materials and
thereafter shall not remove or cause to be removed such materials from the
premises of the Company.

         counterparts, each of which will be deemed an original, but all of
