             CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS

   Certain matters discussed in this prospectus are "forward-looking
statements" intended to qualify for the safe harbors from liability
established by the Private Securities Litigation Reform Act of 1995. These
forward-looking statements can generally be identified as such because the
context of the statement will include words such as "believes", "anticipates",
"expects", "estimates" or words of similar import. Similarly, statements that
describe our future plans, objectives or goals are also forward-looking
statements. Such forward-looking statements are subject to certain risks and
uncertainties which could cause actual results to differ materially from those
anticipated as of the date of this prospectus. The risks and uncertainties
include:

                                      ii
<PAGE>

  . the loss of market share through competition;

  . the introduction of competing technologies by other companies;

  . a prolonged substantial reduction in oil and gas prices which would cause
    a decline in the demand for our compression and oil and gas production
    equipment;

  . new governmental safety, health and environmental regulations which could
    require us to make significant capital expenditures; and

  . changes in economic or political conditions in the countries in which we
    operate.

   The forward-looking statements included herein are only made as of the date
of this prospectus and we undertake no obligation to publicly update such
forward-looking statements to reflect subsequent events or circumstances.

                                  THE COMPANY

   The information provided in this prospectus gives effect to a restructuring
of Hanover Compressor Company that was effected on December 9, 1999 (the
"Restructuring"). The sole purpose of the Restructuring was to create a holding
company, and the Restructuring will have no effect on our business. As a result
of the Restructuring, "old" Hanover Compressor Company was renamed Hanover
Compression Inc. ("HCI") and became a wholly-owned subsidiary of a newly
created holding company called Hanover Compressor Company. Each share of HCI
was exchanged for one share of "new" Hanover Compressor Company, which replaced
"old" Hanover Compressor Company as the publicly held company whose stock is
traded on the New York Stock Exchange. Financial and other information
discussed in this prospectus for periods prior to the Restructuring relates to
HCI and its subsidiaries. Except as described in the previous sentence and
unless the context requires otherwise, "Hanover," "we," "us," "our" or similar
terms in this prospectus refer to "new" Hanover Compressor Company and its
subsidiaries and not the trust.

   We are a leading provider of a broad array of natural gas compression
services in the United States and select international markets. We operate the
largest compressor rental fleet, in terms of horsepower, in the gas compression
industry and provide our services on a rental, contract compression,
maintenance and acquisition leaseback basis. Our customers include independent
and major producers and distributors of natural gas throughout the Western
Hemisphere. Our products and services are essential to the production,
transportation, processing and storage of natural gas. Founded in 1990 and
publicly held since 1997, we are the largest public company whose primary focus
is in the natural gas compression business. Our compression services are
complemented by our compressor and oil and gas production equipment fabrication
operations, which broaden our customer relationships both domestically and
internationally.

   Through internal growth and a series of strategic acquisitions, we have
become the largest operator of rental compression horsepower capacity in the
United States, serving an estimated 28% of the domestic rental market. We began
international operations in 1995 and have become one of the largest providers
of compression services in the rapidly growing Latin American and Canadian
markets. As of September 30, 1999, our compression rental fleet included the
following:

   In addition to our business of providing natural gas compression services,
we also fabricate gas compressors for sale to third parties and for inclusion
in our rental fleet. We were the second largest fabricator of natural gas
compressors (by horsepower) in North America in 1998.

   Complementing our gas compression businesses is our oil and gas production
equipment fabrication business. Oil and gas production equipment is typically
installed at the wellhead immediately before beginning large-scale production
and remains at the site for the life of the well. We fabricate equipment used
by oil and gas producers to separate and treat oil and gas immediately after it
is produced in order to facilitate further processing, transportation and sale.

Industry Overview

   We compete primarily in the transportable natural gas compression market for
units of up to 4,400 horsepower. We believe that aggregate domestic natural gas
compression horsepower grew from approximately 8.8 million horsepower at the
end of 1992 to approximately 13.5 million horsepower at the end of 1998,
reflecting a compound annual growth rate of 9%. We believe that the domestic
gas compression market will continue to grow due to increasing consumption of
natural gas, continued aging of the natural gas reserve base and the attendant
decline of wellhead pressures and the discovery of new reserves.

                                       1
<PAGE>


   We believe that the rental portion of the domestic gas compression market
grew from approximately 1.8 million horsepower at the end of 1992 to
approximately 3.5 million horsepower at the end of 1998, reflecting a compound
annual growth rate of 14%. We believe that the growth in rental compression
capacity in the U.S. has been driven primarily by an increasing trend toward
outsourcing by energy producers and processors. Internationally, we believe
that similar growth opportunities for compressor rental and sales exist due to
anticipated increases in energy consumption worldwide, new international
environmental and conservation laws and increased outsourcing by energy
producers and processors. As worldwide gas consumption continues to grow, we
believe that there will also be a continued demand for the purchase and sale of
gas compression units.

   The oil and gas production equipment industry is more sensitive than the gas
compression industry to the volatility of oil and natural gas prices,
indicating that the growth of this industry will more closely track the growth
of oil and gas production.

Growth Strategy

   Our business strategy is to continue building on our reputation as the
premier operating company in natural gas compression and to grow the rental
fleet in accordance with a proven growth strategy. Our aggressive growth
strategy has generated the following results:

  . aggregate horsepower capacity of our compressor rental fleet grew from
    117,000 horsepower in 1992 to 1,067,000 horsepower in 1998;

  . we maintained average horsepower utilization of approximately 94% from
    1992 to 1998, compared to the average industry utilization which we
    estimate to be approximately 83%;

  . revenues increased from $33.1 million in 1992 to $282.0 million in 1998;

  . earnings before interest, leasing expense, taxes, and depreciation and
    amortization ("EBITDA") increased from $7.3 million in 1992 to $104.7
    million in 1998; and

  . net income grew from $1.0 million in 1992 to $30.4 million in 1998.

   We intend to build on our results to date by continuing to pursue our growth
strategy, which includes the following key elements:

  . delivering a comprehensive range of compression products and services;

  . focusing on higher horsepower compression units;

  . expanding our international operations;

  . broadening our customer base by acquiring compressors from, and leasing
    them back to, our customers;

  . participating in the consolidation of the compression industry;

  . acquiring other companies having assets or businesses which complement
    ours;

  . capitalizing on our decentralized management and operating structure to
    provide superior customer service; and

  . using equity incentives to attract and retain an experienced,
    entrepreneurial, highly motivated management team.

   We believe the successful execution of our growth strategy, combined with
our focus on and leadership position in the compression industry, will enable
us to continue to generate and realize significant growth opportunities.

   Our principal executive office is located at 12001 North Houston Rosslyn,

                                  RISK FACTORS

   An investment in the preferred securities involves risks. You should
carefully consider and evaluate all of the information in this prospectus,
including the following risk factors, before investing.

Risks Relating to Hanover

 Industry Conditions--A prolonged, substantial reduction in oil or gas prices
 could adversely affect our business.

   Our operations depend upon the levels of activity in natural gas
development, production, processing and transportation. In recent years, oil
and gas prices and the level of drilling and exploration activity have been
extremely volatile. For example, from mid-1998 to mid-1999, oil and gas
exploration and development activity and the number of well completions
declined due to a significant reduction in oil and gas prices. As a result, the
demand for our gas compression and oil and gas production equipment was
adversely affected. Any future significant, prolonged decline in oil and gas
prices could have a material adverse effect on our business, results of
operations and financial condition.

 Short Lease Terms--Our compressor leases have short initial terms, and we
 cannot be sure that the compressors will stay out on location after the end
 of the initial lease term.

   The length of our leases varies based on operating conditions and customer
needs. In most cases, under currently prevailing lease rates, the initial lease
terms are not long enough to enable us to fully recoup the average cost of
acquiring or manufacturing the compressors. We cannot assure you that a
substantial number of our lessees will continue to renew their leases or that
we will be able to re-lease the compressors to new customers or that any
renewals or re-leases will be at comparable lease rates. An inability to renew
or re-lease a substantial portion of our compressor rental fleet would have a
material adverse effect upon our business, results of operations and financial
condition.

 Substantial Capital Requirements--We require a substantial amount of capital
 to expand our compressor rental fleet and our complementary businesses.

   We will continue to make substantial capital investments to expand our
compressor rental fleet and our complementary businesses. We had invested
approximately $201 million in capital expenditures as of September 30, 1999,
and we estimate that our capital expenditures in the fourth quarter of 1999
totaled approximately $89 million. We expect to invest approximately $250
million in capital expenditures in 2000. The amount of these expenditures may
vary depending on the rate of return we expect to earn from these investments,
conditions in the natural gas industry and whether we make any significant
acquisitions. Historically, we have funded these investments through internally
generated funds, debt and sale and leaseback transactions and equity financing.
While we believe that cash flow from our operations and borrowings under HCI's
existing $200 million bank credit facility will provide us with sufficient cash
to fund these investments, we cannot assure you that these sources will be
sufficient. HCI would need the consent of the lenders under its bank credit
facility and the lessors under its sale and leaseback transactions to complete
any new financing. Failure to generate sufficient cash flow, together with the
absence of alternative sources of capital, could have a material adverse effect
on our growth, results of operations and financial condition.

 International Operations--There are many risks associated with conducting
 operations in international markets.

   We operate in many different geographic markets, some of which are outside
the United States. Changes in local economic or political conditions,
particularly in Latin America or Canada, could have a material adverse effect
on our business, financial condition and results of operations. Additional
risks inherent in our international business activities include the following:

  . difficulties in managing international operations;

                                       3
<PAGE>

  . unexpected changes in regulatory requirements;

  . tariffs and other trade barriers which may restrict our ability to enter
    into new markets;

  . potentially adverse tax consequences;

  . restrictions on repatriation of earnings;

  . the burden of complying with foreign laws; and

  . fluctuations in currency exchange rates and the value of the U.S. dollar.

 Acquisition Strategy--We may not be able to find suitable acquisition
 candidates or successfully integrate acquired companies into our business.

   As part of our business strategy, we will continue to pursue the acquisition
of other companies, assets and product lines that either complement or expand
our business. Each acquisition involves potential risks, such as the diversion
of management's attention away from current operations, problems in integrating
acquired businesses and possible short-term adverse effects on our operations
as a result of that process. We routinely conduct preliminary discussions with
other companies, which have operations or assets that may be suitable for us to
acquire. Given our selective approach to acquisitions, we are unable to predict
whether or when we will find suitable acquisition candidates or whether we will
be able to complete a material acquisition. We may seek to finance acquisitions
with cash or through the issuance of new debt and/or equity securities. A
relatively large acquisition in which cash is the primary form of consideration
would utilize a substantial portion of our existing financial resources. As the
compression industry continues to consolidate, the size of the companies we may
consider acquiring may become larger and, as a result, the general risks
inherent in acquisitions described above may become more significant.

 Competition--We operate in a highly competitive industry and compete against
 many larger companies with greater financial resources.

   We compete with several large national and multinational companies which
provide compression services to third parties, many of which have greater
financial and other resources than we do. If our competitors were to
substantially increase the resources they devote to the development and
marketing of competitive products and services, we cannot assure you that we
will have sufficient resources to respond accordingly.

 Concentrated Ownership--A significant amount of our stock is owned by one
 stockholder.

   Our largest stockholder, GKH Partners, L.P. ("GKH"), controlled
approximately 40% of our voting power as of December 31, 1999. GKH is in a
position to exert substantial influence over the outcome of most corporate
actions requiring stockholder approval, including the election of directors,
the future issuance by Hanover of common stock or other securities, and the
approval of transactions involving a change of control. The interests of GKH
could conflict with the interests of our other stockholders.

 Anti-Takeover Provisions--Our certificate of incorporation and by-laws
 contain certain provisions that could make a takeover more difficult.

   Certain provisions of our certificate of incorporation and by-laws could
make it more difficult for a third party to acquire control of Hanover, even if
such a change in control would benefit our stockholders. Our certificate of
incorporation allows us to issue preferred stock without stockholder approval
and our by-laws limit who may call special stockholder meetings. These
provisions could make it more difficult for a third party to acquire us and may
discourage acquisition bids or limit the price that investors might be willing
to pay in the future for shares of our common stock. The ownership of a
substantial number of our shares of common stock by GKH and our officers,
directors, employees and their affiliates also could discourage acquisition
bids. There are also provisions of Delaware law that could delay or make
difficult a merger, tender offer or proxy contest. Please read the "Description
of Hanover Capital Stock" section of this prospectus.

<PAGE>

 Potential Liability and Insurance--Natural gas operations entail inherent
 risks that may result in substantial liability to Hanover.

   Natural gas operations entail inherent risks, including equipment defects,
malfunctions, failures and natural disasters which could result in
uncontrollable flows of gas or well fluids, fires and explosions. These risks
may expose us to liability for personal injury, wrongful death, property
damage, pollution and other environmental damage. We have obtained insurance
against liability for personal injury, wrongful death and property damage, but
we cannot assure you that the insurance will be adequate to cover our
liability. Similarly, we cannot assure you that we will be able to obtain
insurance in the future at a reasonable cost or at all. Our business, results
of operations and financial condition could be adversely affected if we incur
substantial liability and the damages are not covered by insurance or are in
excess of policy limits.

 Governmental Regulation--Our business is subject to a variety of governmental
 regulations relating to environmental, health and safety.

   Our business is subject to a variety of federal, state and local laws and
regulations relating to safety, health and the environment. These laws and
regulations are complex, change frequently and have tended to become more
stringent over time. Failure to comply with these laws and regulations may
result in a variety of civil and criminal enforcement measures, including
assessment of monetary penalties, imposition of remedial requirements, and
issuance of injunctions as to future compliance. As part of the regular overall
evaluation of our current operations, we are updating certain facility permits
with respect to stormwater discharges and air emissions but do not believe such
updates will have a material adverse effect on our operations as a result of
any enforcement measures or capital costs. Based on our experience to date, we
believe that the future cost of compliance with existing laws and regulations
and the future cost of necessary investigation or remediation of contamination
will not have a material adverse effect on our business, financial condition
and results of operations. However, future events, such as discovery of unknown
contamination, any third party claims made with respect to previously owned or
leased properties, compliance with more stringent laws and regulations or more
vigorous enforcement policies by regulatory agencies or stricter or different
interpretations of existing laws and regulations could require us to make
material expenditures.

   We have conducted preliminary environmental site assessments with respect to
certain properties currently owned or leased by us. Some of these assessments
have revealed that soils and/or groundwater at some of our facilities are
contaminated with hydrocarbons and various other regulated substances. We do
not believe that our operations caused any such contamination and are not
currently under any orders or directives to undertake any remedial activity. In
addition, we have previously owned or leased certain properties that had in the
past experienced soil contamination. We have since conducted remedial
operations at certain of these previously held properties as we believed
necessary and either sold the owned properties to third parties or returned the
leased properties to the lessors. We are not currently aware of any further
remedial obligations at such previously held properties. We cannot be certain,
however, that we will not be required to undertake any remedial activities
involving any substantial costs on any of these properties in the future.

 Shares Eligible for Future Sale--The market price of our common stock could
 be depressed by future sales.

   Future sales of our common stock, or the perception that these sales could
occur, could adversely affect the market price of our common stock. We cannot
assure you as to when, and how many of, the shares of our common stock will be
sold and the effect those sales may have on the market price of our common
stock. Westar Capital, Inc., which we believe holds approximately 2.9 million
shares of our common stock, has publicly announced this it is reviewing
alternatives to monetize or liquidate these shares. In addition, we may issue
additional shares of common stock in connection with future acquisitions or
other transactions. Although those securities may be subject to regulatory or
contractual resale restrictions, as these restrictions lapse or if these shares
are registered for sale to the public, they may be sold to the public. In the
event we issue a substantial number of shares of our common stock, which
subsequently become available for unrestricted resale, there could be a
material adverse effect on the prevailing market price for our common stock.

Risks Relating to the Preferred Securities

 Subordination--Our obligations under the guarantee and debentures are
 subordinated.

   Because of the subordinated nature of the guarantee and the debentures, we:

  . will not be permitted to make any payments of principal, including
    redemption payments, or interest on the debentures if we default on our
    senior debt, as described under the "Description of Debentures--
    Subordination" section of this prospectus;

  . will not be permitted to make payments on the guarantee if we default on
    any of our senior debt; and

  . must pay all of our senior debt before we make payment on the guarantee
    or the debentures if we become bankrupt, liquidate or dissolve.

   The preferred securities, the guarantee, and the debentures do not limit our
ability or the ability of our subsidiaries to incur additional indebtedness,
including indebtedness that ranks senior to the debentures and the guarantee.
As of October 31, 1999 after giving effect to the Restructuring, Hanover had no
senior debt but had guaranteed approximately $122 million of HCI's indebtedness
under its bank credit agreement. In addition, Hanover has guaranteed the
residual value of the equipment under HCI's sale and lease back transactions of
approximately $332 million, which guarantee ranks senior to the debentures.

 Structural Subordination--The preferred securities and the debentures will be
 effectively subordinated to the obligations of our subsidiaries.

   We are a holding company and we conduct our operations entirely through our
subsidiaries. We have few assets of significance other than the capital stock
of HCI and our other subsidiaries. Consequently, we are dependent upon
dividends or other intercompany transfers of funds from our direct and indirect
subsidiaries to meet our debt service obligations, including those related to
the debentures, the guarantee and the preferred securities. Our subsidiaries
are separate legal entities that have no obligation to pay any amounts due
under the preferred securities, the debentures or the guarantee. Our
subsidiaries do not guarantee the payment of the preferred securities or the
debentures. Furthermore, our subsidiaries are not obligated to make funds
available to us, and creditors of our subsidiaries will have a superior claim
to our subsidiaries' assets. As a result, your right to receive payment on the
debentures and the preferred securities is effectively junior to our
subsidiaries' existing indebtedness and possibly to all of their future
borrowings. In addition, our subsidiaries' ability to make any payments to us
will depend on their earnings, the terms of their indebtedness, business and
tax considerations and legal restrictions.

   Our subsidiaries are permitted to enter into various debt agreements that
restrict their ability to pay dividends, make advances or otherwise distribute
funds to us. We cannot assure you that HCI or any of our other subsidiaries
will be able to pay dividends or otherwise distribute funds to us in an amount
sufficient to pay the principal of or interest on the debentures. At October
31, 1999, after giving effect to the Restructuring, our subsidiaries had
approximately $146 million of debt.

 Tax Consequences of Our Right to Defer Payments--Our right to defer interest
 payments on the debentures has tax consequences for you.

   We can, on one or more occasions, defer interest payments on the debentures
for up to 20 consecutive quarterly periods unless an event of default under the
indenture has occurred and is continuing. We cannot, however, defer interest
payments beyond the earlier of the maturity date of the debentures, which is
December 15, 2029, or the date on which the debentures are redeemed. If we
defer interest payments on the debentures, the trust will also defer
distributions on the preferred securities and the common securities. During a
deferral period, distributions will continue to accumulate on the preferred
securities.

   If we defer payment of interest on the debentures, you will be required to
accrue interest income, as original issue discount, for the deferred interest
allocable to your share of preferred securities for United States

                                       6
<PAGE>

federal income tax purposes. As a result, you will include that income in gross
income for United States federal income tax purposes prior to your receipt of
any cash distributions. In addition, you will not receive cash from the trust
related to that income if you sell your preferred securities prior to the
record date on which those distributions are made. You should consult with your
own tax advisor regarding the tax consequences of an investment in the
preferred securities.

 Market Price Consequences of Our Right to Defer Payments--Our right to defer
 interest payments on the debentures may affect the market price of the
 preferred securities.

   If we defer interest payments on the debentures in the future, the market
price of the preferred securities may not fully reflect the value of accrued
but unpaid interest on the debentures. If you sell preferred securities during
a deferral period, you may not receive the same return on investment as someone
who continues to hold preferred securities. In addition, our right to defer
interest payments on the debentures may mean that the market price for the
preferred securities will be more volatile than other securities that are not
subject to these rights.

 The Guarantee is a Limited Guarantee--The guarantee only guarantees payments
 on the preferred securities if the trust has cash available.

   Our guarantee only applies to the extent that the trust has sufficient funds
to make the payments. If we fail to make payments on the debentures, the trust
will not be able to make the related distribution, redemption or liquidation
payments on the preferred securities. In those circumstances, you will not be
able to rely upon the guarantee for payments of those amounts.

   Instead, if we are in default under the debentures you may:

  . rely on the property trustee of the trust to enforce the trust's rights
    under the debentures; or

  . directly sue us or seek other remedies to collect your pro rata share of
    payments owed.

 Optional Redemption--We may cause the preferred securities to be redeemed on
 or after December 20, 2002 without your consent.

   At our option, we may redeem all or some of the debentures at any time on or
after December 20, 2002. The redemption price you would receive in such an
event may vary, but will not be less than 100% of the principal amount to be
redeemed plus any accrued and unpaid interest. Please read the "Description of
Debentures--Redemption--Optional Redemption" section of this prospectus. You
should assume that we will exercise our redemption option if we are able to
refinance the debentures at a lower interest rate or if it is otherwise in our
interest to redeem the debentures. If a redemption occurs, the trust will use
the cash it receives from the redemption of the debentures to redeem an
equivalent amount of preferred securities and common securities on a pro rata
basis.

 Redemption Upon the Occurrence of a Tax Event--The trust may redeem the
 preferred securities without your consent if specified tax changes occur.

   If specified tax changes occur relating to the non-deductibility of interest
payments on the debentures and certain other conditions are met as are more
fully described under the "Description of Preferred Securities--Tax Event or
Investment Company Event Redemption or Distribution" section of this
prospectus, we may redeem all, but not less than all, of the debentures for the
principal amount of the debentures plus any accrued and unpaid interest on the
debentures. If this happens, the trust will use the cash it receives from the
redemption of the debentures to redeem the preferred securities and the common
securities.

 Distribution of the Debentures--We may, at any time, dissolve the trust and
 distribute the debentures to you which may have adverse tax and other
 consequences for you.

   We may dissolve the trust at any time. If we do so, the trust will, after
satisfaction of liabilities to creditors of the trust as required by applicable
law, redeem the preferred securities and the common securities by distributing
the debentures to you and to us, as holder of the common securities, on a pro
rata basis.

                                       7
<PAGE>

   Under current United States federal income tax laws, a distribution of
debentures on the dissolution of the trust would not be a taxable event to you.
Nevertheless, if the trust is classified for United States federal income tax
purposes as a corporation at the time it is dissolved, the distribution of the
debentures would be a taxable event to you. In addition, if there is a change
in law, a distribution of debentures on the dissolution of the trust could also
be a taxable event to you.

   We have no current intention of dissolving the trust and causing the
distribution of the debentures. However, there are no restrictions on our
ability to do so. We anticipate that we would consider exercising this right if
expenses associated with maintaining the trust were substantially greater than
we currently expect.

   We cannot predict the market prices for the debentures that may be
distributed. Accordingly, the debentures you receive on a distribution, or the
preferred securities you hold pending that distribution, may trade at a
discount to the price you paid to purchase the preferred securities.

   Because you may receive debentures, you should make an investment decision
about the debentures in addition to the preferred securities. You should
carefully review all the information regarding the debentures contained in this
prospectus.

 Lack of an Active Trading Market--We cannot assure you that an active trading
 market for the preferred securities will develop.

   There is no existing market for the preferred securities (or the debentures)
and there can be no assurance as to the liquidity of any markets that may
develop for the preferred securities (or the debentures), the ability of the
holders to sell their preferred securities (or debentures) or at what price
holders of the preferred securities (or the debentures) will be able to sell
such securities. Future trading prices of the preferred securities (and the
debentures) will depend on many factors including:

  . prevailing interest rates;

  . our common stock price;

  . the Company's operating results; and

  . the markets for similar securities.

   The initial purchasers of the preferred securities, Credit Suisse First
Boston Corporation, Goldman Sachs & Co., Salomon Smith Barney, Inc. and Dain
Rauscher Incorporated, currently make a market for the preferred securities
offered hereby; however, the initial purchasers are not obligated to do so and
such market making activity is subject to the limits imposed by applicable law
and may be discontinued at any time without notice.

 Limited Voting Rights--You will have limited voting rights as a holder of
 preferred securities.

   As a holder of preferred securities, you will have limited voting rights
relating only to the modification of the preferred securities and, in specified
circumstances, the exercise of the trust's rights as holder of the debentures
and the guarantee and the appointment of a special trustee. Except as described
in the preceding sentence, only we can replace or remove any of the trustees or
increase or decrease the number of trustees.

 Payment of Dividends--We may not be able to pay dividends on the common stock
 into which your preferred securities may be converted.

   We have no obligation to pay dividends on the common stock into which your
preferred securities may be converted. The declaration and payment of dividends
on our common stock is subject to, and will depend upon, among other things:

  . our future earnings and financial condition, liquidity and capital
    requirements,

  . our ability and the ability of HCI to pay dividends under HCI's bank
    credit agreement,

  . the general economic and regulatory climate and

  . other factors deemed relevant by our board of directors.

   Our guarantee of HCI's senior debt restricts our ability to pay cash
dividends on our common stock.

                                USE OF PROCEEDS

   The Selling Holders will receive all of the proceeds from the sale of the
securities offered by this prospectus. Neither the Company nor the Trust will
receive any of the proceeds from the sale of the securities offered by this
prospectus.

                             ACCOUNTING TREATMENT

   For financial reporting purposes, we will treat the trust as a subsidiary
of Hanover, and accordingly, we will include the accounts of the trust in our
consolidated financial statements. We will present the Preferred Securities in
our consolidated balance sheet as a separate line item entitled "company-
obligated mandatorily redeemable convertible preferred securities." We will
also include appropriate disclosures about the Preferred Securities, the
guarantee and the debentures in the notes to our consolidated financial
statements. For financial reporting purposes, we will record distributions
payable on the Preferred Securities as a financing charge to earnings in our
consolidated statement of income.

                        HANOVER COMPRESSOR CAPITAL TRUST

   Hanover Compressor Capital Trust is a statutory business trust that was
formed under Delaware law on December 1, 1999. The trust's original declaration
of trust was amended and restated in its entirety as of December 15, 1999.

   We own all of the trust's common securities. The common securities represent
common undivided beneficial interests in the assets of the trust with an
aggregate liquidation amount equal to at least 3% of the total capital of the
trust.

   The trust exists for the exclusive purposes of:

  . issuing the preferred securities;

  . issuing the common securities to us;

  . investing the gross proceeds of the sale of the preferred securities and
    the common securities in the debentures;

  . distributing payments received on the debentures to holders of the
    preferred securities and the common securities; and

  . engaging in only those other activities necessary or incidental to such
    purposes.

   The trust currently has five trustees. Three of those trustees, referred to
as administrative trustees, are our employees or officers. Wilmington Trust
Company serves as the trust's property trustee and as the trust's Delaware
trustee. In some circumstances, the holders of a majority of the preferred
securities will be entitled to appoint one additional trustee, referred to as a
special trustee, who does not need to be affiliated with us, who will have the
same rights, powers and privileges as the administrative trustees.

   The property trustee, among other things:

  . holds title to the debentures for the benefit of the holders of the
    preferred securities and the common securities;

  . has the power to exercise all rights, powers and privileges under the
    indenture as the holder of the debentures; and

  . maintains exclusive control of a segregated non-interest bearing bank
    account, called the property account, to hold all payments made in
    respect of the debentures for the benefit of the holders of the preferred
    securities and the common securities.

   Subject to the right of the holders of the preferred securities to appoint a
special trustee, we, as holder of all the common securities, have the right to
appoint, remove or replace any of the trustees and to increase or decrease the
number of trustees. However, the number of trustees is required to be at least
three, a majority of which will be administrative trustees.

   We pay all fees and expenses related to the trust.

   The rights of the holders of the preferred securities, including economic
rights, rights to information and voting rights, are as set forth in the
declaration and the Delaware Business Trust Act, as amended (the "Trust Act").

                      DESCRIPTION OF PREFERRED SECURITIES

   The trust issued the preferred securities pursuant to the terms of the
declaration of trust. The declaration of trust will be qualified under the
Trust Indenture Act and incorporates selected provisions of the Trust Indenture
Act. We have summarized selected provisions of the declaration of trust and the
preferred securities below. This summary is not complete and is subject to, and
is qualified in its entirety by reference to, all the provisions of the
declaration of trust. A copy of the declaration of trust is available upon
request. Unless the context requires otherwise, "Hanover," "we," "us," "our"
and similar terms in this section refer solely to Hanover Compressor Company
after giving effect to the Restructuring and not the trust or any of our other
consolidated subsidiaries.

General

   The declaration of trust authorizes the trust to issue the Preferred
Securities and the common securities. The preferred securities represent
preferred undivided beneficial ownership interests in the assets of the trust.
The common securities represent common undivided beneficial ownership interests
in the assets of the trust. Payments on the preferred securities will be made
pro rata with payments on the common securities, except as described under "--
Subordination of Common Securities." Under a guarantee agreement we guarantee,
on a subordinated basis, any payments required to be made by the trust to the
holders of the preferred securities but only to the extent that the trust has
funds on hand available to make the payments. Please read the "Description of
Guarantee" section of this prospectus.

Distributions

   If you purchase preferred securities you will be entitled to receive cash
distributions at an annual rate of 7 1/4% of the $50 stated liquidation amount
per each preferred securities. Distributions are cumulative and will begin to
accumulate on the date of original issuance of the preferred securities.
Distributions will be payable quarterly in arrears March 15, June 15, September
15 and December 15, of each year beginning March 15, 2000, to the person in
whose name each of the preferred securities is registered, subject to certain
exceptions, at the close of business on the first day of the month of the
applicable distribution date.

   The amount of distributions payable for any period will be computed on the
basis of the number of days elapsed in a 360-day year consisting of twelve 30-
day months. If a distribution date is not a business day, the trust will make
the distributions on the next day that is a business day, without any
additional distributions or other payments due to the delay.

   Accrued distributions that are not paid on the applicable distribution date
will accrue additional distributions compounded quarterly from the relevant
distribution date. For the purpose of this prospectus, a "distribution" will
include quarterly distributions, additional distributions on quarterly
distributions not paid on the applicable distribution date, special
distributions (as described in the "Registration Rights" section of this
prospectus) and additional sums (as described in the "Description of
Debentures--Additional Sums" section of this prospectus), as applicable. A
"business day" is any day other than a Saturday or a Sunday, or a day on which
banking institutions in New York, New York or Wilmington, Delaware are
authorized or required by law or executive order to remain closed, or a day on
which the corporate trust office of the property trustee or the debenture
trustee is closed for business.

 Option to Defer Distributions

   We can, on one or more occasions, defer interest payments on the debentures
for up to 20 consecutive quarterly periods unless an event of default under the
indenture has occurred and is continuing. Interest payments will not be due and
payable on the debentures during a deferral period. We cannot, however, defer
interest payments beyond the earlier of the maturity date of the debentures,
which is December 15, 2029, or the date the debentures are redeemed.

                                       11
<PAGE>

   If we defer interest payments on the debentures, the trust will defer
distribution payments on the preferred securities and the common securities.
Distributions will continue to accumulate on the preferred securities and the
common securities during a deferral period. Also, additional cash
distributions will accumulate on any deferred distributions at the annual rate
of 7 1/4%, compounded quarterly.

   We do not currently intend to defer interest payments on the debentures.

   We may extend a deferral period prior to the period's termination. However,
we may not extend a deferral period, including all previous and further
extensions of the period, beyond 20 consecutive quarterly interest periods or
the maturity date of the debentures. Once a deferral period ends and we make
all payments due on the debentures, we can commence a new deferral period.
Consequently, there could be multiple deferral periods of varying lengths
throughout the term of the debentures. Please read the "Federal Income Tax
Consequences--Interest Income and Original Issue Discount" section of this
prospectus.

 Payment of Distributions

   The trust must pay distributions on the preferred securities on the
distribution payment dates to the extent that the property trustee has cash on
hand to make distributions. The property trustee will maintain that cash in
the property account. The only funds the property trustee will have to
distribute to the holders of the preferred securities will be from payments
received on the debentures. If we do not make interest payments on the
debentures, the property trustee will not have funds available to make
distributions on the preferred securities. If and to the extent we make
interest payments on the debentures, the property trustee will be obligated to
make distributions on the preferred securities and the common securities on a
pro rata basis. We guarantee the payment of distributions and other payments
on the preferred securities on a subordinated basis, but only if, and to the
extent, we have made corresponding payments to the trust on the debentures
and, as a result, the property trustee has funds available to make
distributions on the preferred securities. Please read the "Description of the
Guarantee" section in this prospectus.

Conversion Rights

 General

   Holders of preferred securities may convert them into our common stock at
any time before the earlier of:

  . the close of business on the business day immediately prior to the
    maturity date of the debentures; or

  . in the case of preferred securities called for redemption, the close of
    business on the business day immediately prior to the redemption date.

   Initially, each of the preferred securities is convertible, at the option
of the holder, into 1.3986 shares of our common stock. This conversion rate is
equivalent to a conversion price of $35.75 per share of our common stock. The
conversion rate and conversion price will be subject to adjustment as
described under the "--Conversion Price Adjustments" section of this
prospectus.

   If you wish to exercise your conversion right, you must deliver an
irrevocable conversion notice, together, if the preferred securities are in
certificated form, with the certificated security, to the conversion agent who
will, on your behalf, exchange the preferred securities for a like amount of
debentures and immediately convert the debentures into shares of our common
stock. You may obtain copies of the required form of the conversion notice
from the conversion agent.

   At the close of business on a distribution record date, you will be
entitled to receive the distribution payable on your preferred securities on
the corresponding distribution date even if you convert your preferred
securities after the distribution record date but prior to the distribution
date. Except as provided in the immediately preceding sentence, neither we nor
the trust will make, or be required to make, any payment, allowance or
adjustment for accrued and unpaid distributions, whether or not in arrears, on
converted preferred

                                      12
<PAGE>

securities, even if you convert you preferred securities during a deferral
period. We will make no payment or allowance for distributions on our shares of
common stock issued upon conversion, except to the extent that those shares of
common stock are held of record on the record date for any distributions. We
will deem each conversion to have been effected immediately prior to the close
of business on the day on which the trust received the related conversion
notice.

   We will not issue any fractional shares of our common stock as a result of a
conversion of preferred securities. We will pay cash in lieu of a fractional
share of common stock.

 Conversion Price Adjustments--General.

   The conversion price will be subject to adjustment for some events,
including:

  . the payment of dividends or distributions payable in our common stock on
    our common stock;

  . the issuance of rights or warrants to all holders of our common stock;

  . subdivisions and combinations of our common stock;

  . the payment of dividends or distributions to all holders of our common
    stock consisting of our indebtedness, securities or capital stock, cash
    or assets, excluding any rights, warrants, dividends or distributions
    referred to in the first two bullet points and dividends and
    distributions paid exclusively in cash;

  . the payment of dividends or other distributions on our common stock
    exclusively in cash, excluding:

    . cash dividends that do not exceed the per share amount of the
      smallest of the four immediately preceding quarterly cash dividends
      as adjusted to reflect any of the events referred to in the
      proceeding bullet points; and

    . cash dividends, if the annualized per share amount of the cash
      dividends does not exceed 12.5% of the market price of our common
      stock on the trading day immediately prior to the date of declaration
      of the dividend; and

  . payment to holders of our common stock in respect of a tender or exchange
    offer, other than an odd-lot offer by us or any subsidiary of ours, for
    our common stock at a price in excess of 110% of the market price of our
    common stock as of the trading day next succeeding the last date tenders
    or exchanges may be made in the tender or exchange offer.

   We may, at our option, make other reductions in the conversion price that
our board of directors determines are advisable to avoid or diminish any income
tax to holders of our common stock resulting from any dividend or distribution
of stock or rights to acquire stock or from any event treated as such for
income tax purposes. Please read the "Federal Income Tax Consequences--
Adjustment of Conversion Price" section of this prospectus.

   The conversion price will not be adjusted for the issuance of our common
stock (or securities convertible into or exchangeable for our common stock),
except as described above. For example, the conversion price will not be
adjusted upon the issuance of shares of our common stock

  . under any present or future plan providing for the reinvestment of
    dividends or interest payable on our securities;

  . in connection with the investment of additional optional amounts in
    shares of our common stock under any plan described in the preceding
    bullet point;

  . under any present or future employee benefit plan or program of ours; or

  . pursuant to any option, warrant, right, or exercisable, exchangeable or
    convertible security outstanding as of the date the preferred securities
    were first issued.


                                       13
<PAGE>

   If any action would require adjustment of the conversion price under more
than one of the provisions described above, only one adjustment will be made
and that adjustment will be the amount of adjustment that has the highest
absolute value to holders of the preferred securities. An adjustment in the
conversion price will not be required unless the adjustment would require a
change of at least 1% in the conversion price then in effect.

   However, any adjustment that would otherwise be required to be made will be
carried forward and taken into account in any subsequent adjustment.

 Conversion Price Adjustments--Merger, Consolidation or Sale of Assets

   If we are a party to any transaction, including a merger, consolidation,
sale of all or substantially all of our assets, recapitalization or
reclassification of our common stock or any compulsory share exchange, that
results in shares of our common stock being converted into the right to receive
other securities, cash or other property, then lawful provision will be made as
part of the terms of the transaction so that the holders of the preferred
securities will have the right to convert each Preferred Securities into:

  . in the case of any transaction other than a transaction involving a
    Common Stock Fundamental Change (as defined below), the kind and amount
    of securities, cash or other property receivable upon the consummation of
    the transaction by a holder of that number of shares of our common stock
    into which a preferred securities was convertible immediately prior to
    the transaction; or

  . in the case of a transaction involving a Common Stock Fundamental Change,
    common stock of the kind received by holders of our common stock.

   In each case described in the foregoing bullet points, the conversion will
be made after giving effect to any adjustment discussed below relating to a
Fundamental Change if the transaction constitutes a Fundamental Change. The
holders of preferred securities will have no voting rights with respect to any
transaction described in this section.

   If a Fundamental Change occurs, the conversion price in effect immediately
before the Fundamental Change will be adjusted as described below.

   In the case of a Non-Stock Fundamental Change, the conversion price of the
preferred securities will be adjusted to become the lower of:

  . the conversion price in effect immediately prior to the Non-Stock
    Fundamental Change, but after giving effect to any other adjustments that
    may be made pursuant to the first paragraph under the "--Conversion Price
    Adjustments--General" section of this prospectus; and

  . the result obtained by multiplying the greater of the Relevant Price (as
    defined below) or the then applicable Reference Market Price (as defined
    below) by the Optional Redemption Ratio (as defined below) (such product
    shall be referred to as the "Adjusted Relevant Price" or the "Adjusted
    Reference Market Price," as the case may be).

   In the case of a Common Stock Fundamental Change, the conversion price of
the preferred securities in effect immediately before the Common Stock
Fundamental Change, but after giving effect to any other prior adjustments,
will thereupon be adjusted by multiplying the conversion price by a fraction of
which the numerator will be the Purchaser Stock Price (as defined below) and
the denominator will be the Relevant Price; provided, however, that in the
event of a Common Stock Fundamental Change in which:

  . 100% of the value of the consideration received by a holder of our common
    stock is common stock of the successor, acquiror or other third party
    (and cash, if any, is paid only with respect to any fractional interests
    in that common stock resulting from such Common Stock Fundamental
    Change); and

                                       14
<PAGE>

  . all of our common stock will have been exchanged for, converted into, or
    acquired for common stock (and cash with respect to fractional interests)
    of the successor, acquiror or other third party,

the conversion price of the preferred securities in effect immediately before
the Common Stock Fundamental Change will be adjusted by multiplying the
conversion price by a fraction of which the numerator will be one and the
denominator will be the number of shares of common stock of the successor,
acquiror, or other third party received by a holder of one share of our common
stock as a result of the Common Stock Fundamental Change.

   In the absence of the adjustments to the conversion price after a
Fundamental Change, in the case of a transaction mentioned above, each
preferred securities would become convertible into the securities, cash, or
other property receivable by a holder of the number of shares of our common
stock into which each preferred securities was convertible immediately prior to
the transaction. As a result, in the absence of the Fundamental Change
provisions, a transaction could substantially lessen or eliminate the value of
the conversion privilege associated with the preferred securities. For example,
if we are acquired in a cash merger, each preferred securities would become
convertible solely into cash and would no longer be convertible into securities
whose value would vary depending on our future prospects and other factors.

   In Non-Stock Fundamental Change transactions, the foregoing conversion price
adjustments are designed to increase the securities, cash or other property
into which each preferred securities is convertible. In a Non-Stock Fundamental
Change transaction where the initial value received per share of our common
stock (measured as described in the definition of Relevant Price) is lower than
the conversion price of the preferred securities but greater than or equal to
the Reference Market Price, the conversion price will be adjusted as described
above with the effect that each preferred securities will be convertible into
securities, cash or other property of the same type received by the holders of
our common stock in the transaction with the conversion price adjusted as
though the initial value had been the Adjusted Relevant Price.

   In a Non-Stock Fundamental Change transaction where the initial value
received per share of our common stock (measured as described in the definition
of Relevant Price) is lower than both the conversion price of each preferred
securities in effect immediately before any adjustment described above and the
Reference Market Price, the conversion price will be adjusted as described
above but calculated as though the initial value had been the Adjusted
Reference Market Price.

   In Common Stock Fundamental Change transactions, the adjustments described
above are designed to provide in effect that:

  . where our common stock is converted partly into common stock and partly
    into other securities, cash or property, each preferred securities will
    be convertible solely into a number of shares of common stock determined
    so that the initial value of those shares (measured as described in the
    definition of Purchaser Stock Price below) equals the value of the shares
    of our common stock into which the preferred securities was convertible
    immediately before the transaction (measured as described above) and

  . where our common stock is converted solely into common stock, each
    preferred securities will be convertible into the same number of shares
    of common stock receivable by a holder of the number of shares of our
    common stock into which the preferred securities was convertible
    immediately before the transaction.

   "Closing Price" of any security on any day means the last reported sale
price of that security on that day, or if no sale takes place on that day, the
average of the closing bid and asked prices in each case on the principal
national securities exchange on which the securities are listed or admitted to
trading or, if not listed or admitted to trading on any national securities
exchange, on the National Market System of the Nasdaq Stock Market or any
successor national automated interdealer quotation system (the "Nasdaq Stock
Market") or, if such securities are not listed or admitted to trading on any
national securities exchange or quoted on the

                                       15
<PAGE>

Nasdaq Stock Market, the average of the closing bid and asked prices of that
security in the over-the-counter market as furnished by any New York Stock
Exchange member firm selected by us for that purpose.

   "Common Stock Fundamental Change" means any Fundamental Change in which more
than 50% of the value, as determined in good faith by our board of directors,
of the consideration received by holders of our common stock consists of common
stock that for each of the ten consecutive trading days immediately prior to
and including the Entitlement Date has been admitted for listing or admitted
for listing subject to notice of issuance on a national securities exchange or
quoted on the Nasdaq Stock Market; provided, however, that a Fundamental Change
will not be a Common Stock Fundamental Change unless either:

  . we continue to exist after the occurrence of the Fundamental Change and
    the outstanding preferred securities continue to exist as outstanding
    Preferred Securities; or

  . not later than the occurrence of such Fundamental Change, the outstanding
    debentures are converted into or exchanged for debentures of a
    corporation succeeding to the business of our company, which debentures
    have terms substantially similar to those of the debentures.

   "Entitlement Date" means the record date for determination of the holders of
our common stock entitled to receive securities, cash or other property in
connection with a Non-Stock Fundamental Change or a Common Stock Fundamental
Change or, if there is no record date, the date on which holders of our common
stock will have the right to receive such securities, cash or other property.

   "Fundamental Change" means the occurrence of any transaction or event in
connection with a plan under which all or substantially all of our common stock
will be exchanged for, converted into, acquired for or constitute solely the
right to receive securities, cash or other property (whether by means of an
exchange offer, liquidation, tender offer, consolidation, merger, combination,
reclassification, recapitalization or otherwise); provided that, in the case of
a plan involving more than one of these transactions or events, for purposes of
adjustment of the conversion price, the Fundamental Change will be deemed to
have occurred when substantially all of our common stock will be exchanged for,
converted into, or acquired for or constitute solely the right to receive
securities, cash, or other property, but the adjustment will be based upon the
highest weighted average per share consideration that a holder of our common
stock could have received in that transaction or event as a result of which
more than 50% of our common stock will have been exchanged for, converted into,
or acquired for or constitute solely the right to receive securities, cash or
other property.

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

   "Optional Redemption Ratio" means a fraction of which the numerator will be
$50 and the denominator will be the then current redemption price or, prior to
December 20, 2002, an amount per preferred securities determined by us in our
sole discretion, after consultation with an investment banking firm, to be the
equivalent of the hypothetical redemption price that would have been applicable
if the preferred securities had been redeemable during such period.

   "Purchaser Stock Price" means, with respect to any Common Stock Fundamental
Change, the average of the Closing Prices for the common stock received in the
Common Stock Fundamental Change for the ten consecutive trading days prior to
and including the Entitlement Date, as adjusted in good faith by us to
appropriately reflect any of the events referred to in the first paragraph
under the "--Conversion Price Adjustments--General" section of this prospectus.

   "Reference Market Price" initially means $20.17 (which is an amount equal to
66 2/3% of the last reported sale price for our common stock on the New York
Stock Exchange Composite Transactions Tape on December 9, 1999), and, in the
event of any adjustment to the conversion price, other than as a result of a
Non-Stock Fundamental Change, the Reference Market Price will also be adjusted
so that the ratio of the Reference Market Price to the conversion price after
giving effect to the adjustment will always be the same as the ratio of $20.17
to the initial conversion price of the preferred securities.

                                       16
<PAGE>

   "Relevant Price" means (a) in the case of a Non-Stock Fundamental Change in
which the holder of our common stock receives only cash, the amount of cash
received by the holder of one share of our common stock; and (b) in the event
of any other Non-Stock Fundamental Change or any Common Stock Fundamental
Change, the average of the daily Closing Prices for our common stock during the
ten consecutive trading days prior to and including the Entitlement Date, in
each case as adjusted in good faith by us to appropriately reflect any of the
events referred to in the first paragraph under the "--Conversion Price
Adjustments--General" section of this prospectus.

Mandatory Redemption

   When the debentures are repaid in full at their stated maturity or the
debentures are redeemed in whole or in part (other than following any
distribution of the debentures to the holders of the preferred securities and
common securities), the proceeds from the repayment or redemption of the
debentures will be applied to redeem, on a pro rata basis, an equivalent
liquidation amount of preferred securities and common securities. The
redemption price for each preferred securities on any such redemption will be
equal to:

  . the liquidation amount of each preferred securities plus any accrued and
    unpaid distributions on the preferred securities in the case of (a) the
    repayment of the debentures at their stated maturity or (b) the
    redemption of the debentures in some limited circumstances upon the
    occurrence of a tax event; or

  . the redemption price described under the "Description of Debentures--
    Redemption--Optional Redemption" section of this prospectus in the case
    of an optional redemption of the debentures on or after December 20,
    2002.

Redemption Procedures

   If the trust gives a redemption notice for the preferred securities, then,
by 12:00 noon, New York City time, on the redemption date and provided that we
have paid to the property trustee a sufficient amount of cash for the
redemption, and the preferred securities are held in global form, the property
trustee will:

  . deposit with DTC funds sufficient to pay the applicable redemption price;
    and

  . give DTC irrevocable instructions and authority to pay the applicable
    redemption price to the holders of the preferred securities.

   For preferred securities held in certificated form, the property trustee
will:

  . deposit with the paying agent for the preferred securities funds
    sufficient to pay the applicable redemption price; and

  . give the paying agent irrevocable instructions and authority to pay the
    redemption price to the holders of the preferred securities upon
    surrender of their certificates evidencing the preferred securities.

   Distributions payable on or prior to the applicable redemption date will be
payable to the holders of the preferred securities on the relevant record dates
for the related distribution dates. If notice of redemption has been given and
funds have been deposited as required, then upon the date of the deposit, all
rights of the holders of the preferred securities will cease, except the right
of the holders of the preferred securities to receive the applicable redemption
price, but without interest on such redemption price, and the preferred
securities will cease to be outstanding.

   If a date fixed for redemption is not a business day, then payment of the
redemption price payable on that date will be made on the next day that is a
business day, and without any interest or other payment because of the delay.
However, if the next business day falls in the next calendar year, the payment
will be made on the immediately preceding business day. Payment made in either
of these cases will have the same effect as if made on the date fixed for
redemption. If payment of the redemption price is improperly withheld or
refused and not paid either by the property trustee or by us pursuant to the
guarantee, distributions on the preferred

                                       17
<PAGE>

securities will continue to accrue from the original redemption date of the
preferred securities to the date the redemption price is actually paid. In that
case, the actual payment date will be the date fixed for redemption for
purposes of calculating the redemption price and accrued interest.

   Subject to applicable law, we or our subsidiaries may at any time purchase
outstanding preferred securities by tender, in the open market or by private
agreement.

   If we desire to consummate an optional redemption we must send a notice to
each holder of preferred securities at its registered address in accordance
with the notice procedures set forth under the "Description of Debentures--
Redemption--Optional Redemption" section of this prospectus. Notice of a
redemption due to a tax event must be mailed at least 20 days but not more than
60 days before the redemption date to each holder of preferred securities.
Notice of repayment at the stated maturity of the debentures is not required.

Tax Event or Investment Company Event Redemption or Distribution

 Tax Event

   If a tax event occurs, we will cause the trustees to dissolve the trust and,
after satisfaction of liabilities to creditors of the trust as required by
applicable law, distribute the debentures to the holders of the preferred
securities within 90 days following the occurrence of the tax event. However,
such a liquidation and distribution will be conditioned on:

  . the trustees' receipt of an opinion of nationally recognized independent
    tax counsel experienced in such matters that the holders of the preferred
    securities will not recognize any income, gain or loss for United States
    federal income tax purposes as a result of distribution of the
    debentures; and

  . our being unable to avoid the tax event within the 90-day period by
    taking some ministerial action or pursuing some other reasonable measure
    that, in our sole judgment, will have no adverse effect on the trust, us
    or the holders of the preferred securities and will involve no material
    cost.

   Furthermore, if a tax event occurs and:

  . we receive an opinion of nationally recognized independent tax counsel
    experienced in such matters that, as a result of a tax event, there is
    more than an insubstantial risk that we would be precluded from deducting
    the interest on the debentures for United States federal income tax
    purposes, even after the debentures were distributed to the holders of
    the preferred securities upon liquidation of the trust as described
    above; or

  . the trustees are informed by such tax counsel that it cannot deliver the
    opinion contemplated by the immediately preceding paragraph,

then we will have the right, upon not less than 20 nor more than 60 days'
notice and within 90 days following the occurrence and continuation of the tax
event, to redeem the debentures, in whole, but not in part, for cash, for the
principal amount of the debentures plus accrued and unpaid interest on the
debentures and, following the redemption, all the preferred securities will be
redeemed by the trust at their aggregate liquidation amount plus accrued and
unpaid distributions on the preferred securities. However, if at the time there
is available to us or the trust the opportunity to eliminate, within a 90-day
period, the tax event by taking some ministerial action or pursuing some other
reasonable measure that, in our sole judgment, will have no adverse effect on
us, the trust or the holders of the preferred securities and will involve no
material cost, either we or the trust will pursue such measure in lieu of
redemption. In lieu of the foregoing options, we will also have the option of
causing the preferred securities to remain outstanding and pay additional sums
on the debentures as described below in the "Description of Debentures--
Additional Sums" section of this prospectus.

   A tax event will occur upon the receipt by the property trustee of an
opinion of a nationally recognized independent tax counsel experienced in such
matters to the effect that, on or after the date of original issuance of the
preferred securities, as a result of:

                                       18
<PAGE>

  . any amendment to or change, including any announced prospective change
    (provided that a tax event will not occur more than 90 days before the
    effective date of any such prospective change), in the laws of the United
    States or any political subdivision or taxing authority thereof or
    therein;

  . any judicial decision or official administrative pronouncement, ruling,
    regulatory procedure, notice or announcement, including any notice or
    announcement of intent to adopt such procedures or regulations; or

  . any amendment to or change in the administrative position or
    interpretation of any judicial decision or official administrative
    pronouncement, ruling, regulatory procedure, notice or announcement, or
    judicial decision that differs from the previously generally accepted
    position, in each case, by any legislative body, court, governmental
    agency or regulatory body, irrespective of the manner in which such
    amendment or change is made known, which amendment or change is effective
    or such amendment or change is announced

   there is more than an insubstantial risk that:

    . if the debentures are held by the property trustee, (a) the trust is,
      or will be within 90 days of the date of the opinion, subject to
      United States federal income tax with respect to interest accrued or
      received on the debentures or subject to more than a de minimis amount
      of other taxes, duties or other governmental charges or (b) any
      portion of interest payable by us to the trust on the debentures is
      not, or within 90 days of the date of the opinion will not be,
      deductible by us in whole or in part for United States federal income
      tax purposes; or

    . with respect to debentures that are no longer held by the property
      trustee, any portion of interest payable by us on the debentures is
      not, or within 90 days of the date of the opinion will not be,
      deductible by us in whole or in part for United States federal income
      tax purposes.

 Investment Company Event

   If an investment company event occurs and is continuing, we will cause the
trustees to dissolve the trust and, after satisfaction of liabilities to
creditors of the trust as required by applicable law, cause the debentures to
be distributed to the holders of the preferred securities in liquidation of the
trust within 90 days following the occurrence of the investment company event.

   An investment company event will occur upon the receipt by the property
trustee of an opinion of nationally recognized independent securities counsel
to the effect that on or after the date of original issuance of the preferred
securities, as a result of a change in law or regulation or a written change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, the trust is or will be
considered an investment company that is required to be registered under the
Investment Company Act of 1940, as amended.

   The distribution by us of the debentures will effectively result in the
cancellation of the preferred securities.

Liquidation of the Trust and Distribution of the Debentures

   We will have the right at any time to dissolve the trust and, after
satisfaction of liabilities to creditors of the trust as required by applicable
law, cause an equivalent principal amount of the debentures to be distributed
to the holders of the preferred securities in liquidation of the trust.

   In addition, the trust will automatically dissolve upon the first to occur
of:

  . specified events of bankruptcy, dissolution or liquidation of Hanover;

                                       19
<PAGE>

  . upon our election to distribute all of the debentures to the holders of
    the preferred securities and the common securities in exchange for all of
    the preferred securities and common securities in accordance with the
    terms of the preferred securities and common securities;

  . redemption of all the preferred securities and common securities as
    described under "--Mandatory Redemption" above;

  . conversion of all outstanding preferred securities and the trust's common
    securities as described under "--Conversion Rights" above;

  . December 1, 2049, the expiration of the trust's term; and

  . upon a decree of judicial dissolution.

   If an early dissolution occurs as described in the first, second or sixth
bullet points above, the trustees will liquidate the trust as expeditiously as
possible by distributing, after satisfaction of liabilities to the trust's
creditors as required by applicable law, to the holders of the preferred
securities and common securities an equivalent principal amount of debentures.
However, if the distribution of debentures is not practical, the holders of
preferred securities will be entitled to receive out of the assets of the trust
available for distribution to holders of preferred securities, an amount equal
to the aggregate liquidation amount of the preferred securities plus accrued
and unpaid distributions of the preferred securities to the date of payment. If
this amount can be paid only in part because the trust has insufficient assets
available to pay the full amount, then the amounts payable directly by the
trust on the preferred securities will be paid on a pro rata basis. We, as
holder of the common securities, will be entitled to receive distributions upon
any such liquidation pro rata with the holders of the preferred securities.
However, if an event of default under the indenture or declaration of trust has
occurred and is continuing, the preferred securities will have a priority over
the common securities with respect to any distributions.

   On and after the liquidation date fixed for any distribution of debentures
to holders of the preferred securities and common securities:

  . the preferred securities will no longer be deemed to be outstanding;

  . DTC or its nominee, as the record holder of the preferred securities,
    will receive a registered global certificate or certificates representing
    the debentures to be delivered upon such distribution with respect to
    preferred securities held by DTC or its nominee; and

  . any certificates representing preferred securities not held by DTC or its
    nominee will be deemed to represent debentures having a principal amount
    equal to the liquidation amount of such preferred securities and bearing
    accrued and unpaid interest in an amount equal to the accumulated and
    unpaid distributions on such preferred securities until certificates are
    presented to the administrative trustees or their agent for cancellation,
    whereupon we will issue to such holder, and the debenture trustee will
    authenticate, a certificate representing the debentures.

Subordination of Common Securities

   Payment on the preferred securities will be made pro rata with payments on
the common securities based on the liquidation amount of the securities.
However, if on a distribution date or redemption date, as the case may be, an
event of default under the indenture or declaration of trust has occurred and
is continuing, no payment may be made on the common securities.

   In the case of any event of default under the declaration of trust resulting
from an event of default under the indenture, we, as holder of the common
securities, will be deemed to have waived any right to act with respect to any
such event of default under the declaration of trust until the effect of all
such events of default have been cured, waived or otherwise eliminated. Until
all of the events of default under the declaration of trust have been cured,
waived or otherwise eliminated, the property trustee will act solely on behalf
of the holders of

                                       20
<PAGE>

the preferred securities and not on our behalf, and only the holders of the
preferred securities will have the right to direct the property trustee to act
on their behalf.

Events of Default; Notice

   Any one of the following events constitutes an event of default under the
declaration of trust:

  . the occurrence of an event of default under the indenture;

  . default by the trust in the payment of any distribution when it becomes
    due and payable, and continuation of such default for a period of 30 days
    (subject to the deferral of any due date in the case of a deferral
    period);

  . default by the trust in the payment of any redemption price of any
    preferred securities when it becomes due and payable;

  . default in the performance, or breach, in any material respect, of any
    other covenant or warranty of the trustees in the declaration of trust,
    and continuation of such default or breach for a period of 60 days after
    there has been given written notice of the breach by the holders of at
    least 25% in aggregate liquidation amount of the outstanding preferred
    securities; or

  . the occurrence of certain events of bankruptcy or insolvency with respect
    to the property trustee and our failure to appoint a successor property
    trustee within 60 days thereof.

   We and the administrative trustees are required to file annually with the
property trustee a certificate as to whether or not we are in compliance with
all the conditions and covenants applicable to us under the declaration of
trust.

Removal of Trustees

   Unless an event of default under the indenture occurs and is continuing, we
may remove any trustee at any time. If an event of default under the indenture
has occurred and is continuing, the property trustee and the Delaware trustee
may be removed at that time only by the holders of a majority in liquidation
amount of the outstanding preferred securities. The holders of the preferred
securities do not have the right to appoint, remove or replace the
administrative trustees. We have the exclusive right, as the holder of the
common securities, to appoint, remove or replace the administrative trustees. A
resignation or removal of the Delaware trustee or the property trustee and an
appointment of a successor trustee will not be effective until the acceptance
of appointment by the successor trustee in accordance with the provisions of
the declaration of trust.

Co-trustees and Separate Property Trustee

   Unless an event of default under the indenture has occurred and is
continuing, at any time, 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, we, as the holder of the common
securities, and the administrative trustees may appoint one or more persons
either to act as a co-trustee, jointly with the property trustee, of all or any
part of the trust's property, or to act as separate trustee of any of the
trust's property. If an event of default under the indenture has occurred and
is continuing, the property trustee alone will have the power to make the
appointment.

Mergers, Consolidations, Amalgamations or Replacements of the Trust

   The trust may not merge with or into, consolidate, amalgamate or be replaced
by, or convey, transfer or lease its properties and assets substantially as an
entirety to any corporation or other person, except as described below or as
otherwise set forth in the declaration of trust. The trust may, with the
consent of the administrative trustees and without the consent of the holders
of the preferred securities, the property trustee or

                                       21
<PAGE>

the Delaware trustee, merge with or into, consolidate, amalgamate or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, a trust organized under the laws of any state
of the United States or the District of Columbia if:

  . the trust is not the surviving entity, the successor entity either (a)
    expressly assumes all of the obligations of the trust with respect to the
    preferred securities or (b) substitutes for the preferred securities
    other securities having substantially the same terms as the preferred
    securities so long as the successor securities rank the same as the
    preferred securities;

  . a trustee of the successor entity possessing the same powers and duties
    as the property trustee as the holder of the debentures is appointed;

  . the preferred securities or any successor securities are listed, or any
    successor securities will be listed upon notification of issuance, on any
    national securities exchange or other organization on which the preferred
    securities are then listed or quoted, if any;

  . the transaction does not cause the preferred securities (including any
    successor securities) to be downgraded by any nationally recognized
    statistical rating agency then rating the preferred securities;

  . the transaction does not adversely affect the rights, preferences and
    privileges of the holders of the preferred securities (including any
    successor securities) in any material respect;

  . the successor entity has a purpose substantially identical to that of the
    trust;

  . prior to the transaction, we receive an opinion from independent counsel
    experienced in such matters to the effect that (a) the successor entity
    will be treated as a grantor trust for United States federal income tax
    purposes, (b) following the transaction, neither the trust nor the
    successor entity will be required to register as an investment company
    under the 1940 Act, and (c) the transaction will not adversely affect the
    limited liability of the holders of the trust securities (including any
    successor securities);

  . we or any permitted successor or assignee will own all of the common
    securities of the successor entity and will guarantee the obligations of
    the successor entity under the successor securities at least to the
    extent provided by the guarantee; and

  . the transaction is not a taxable event for holders of the preferred
    securities.

   Notwithstanding the foregoing, the trust will not, except with the consent
of holders of 100% in liquidation amount of the preferred securities and common
securities, consolidate, amalgamate, merge with or into, or be replaced by or
convey, transfer or lease its properties and assets substantially as an
entirety to, any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it, if the transaction would cause
the trust or the successor entity to be classified as an association taxable as
a corporation, or substantially increase the likelihood that the trust or the
successor entity would not be classified as a grantor trust for United States
federal income tax purposes.

Voting Rights; Amendment of the Declaration

   Except as provided below and under the "Description of Guarantee--Amendments
and Assignment" section of this prospectus and as otherwise required by law and
the declaration of trust, the holders of the preferred securities will have no
voting rights.

   In addition to the rights of the holders of preferred securities to enforce
payment to the trust of the principal or interest on the debentures described
in the "Description of Debentures--Enforcement of Certain Rights by Holders of
Preferred Securities" section of this prospectus, if an event of default under
the indenture occurs and is continuing or we default under the guarantee with
respect to the preferred securities, then the holders of the preferred
securities will be entitled by the majority vote of the holders to appoint a
special trustee. Any holder of preferred securities other than us and our
affiliates will be entitled to nominate a special trustee. Not later than 30
days after the right to appoint a special trustee arises, the trustees will
convene a

                                       22
<PAGE>

meeting of the holders of the preferred securities for the purpose of
appointing a special trustee. If the trustees fail to convene the meeting
within the 30-day period, the holders of not less than 10% of the aggregate
liquidation amount of the outstanding preferred securities will be entitled to
convene the meeting. Any appointed special trustee will cease to be a special
trustee if the event that caused the appointment is cured. Regardless of the
appointment of a special trustee, we will retain all rights under the
indenture.

   The declaration of trust may be amended by us, the property trustee and the
administrative trustees without the consent of the holders of the preferred
securities:

  . to cure any ambiguity, correct or supplement any provision in the
    declaration of trust that may be inconsistent with any other provision of
    the declaration of trust, or to make provisions with respect to
    ministerial matters or questions arising under the declaration of trust,
    which are not inconsistent with the other provisions of the declaration
    of trust; or

  . to modify, eliminate or add to any provisions of the declaration of trust
    to the extent as is necessary to ensure that (a) the trust will not be
    taxable as a corporation and will continue to be classified for United
    States federal income tax purposes as a grantor trust at all times that
    any preferred securities or common securities are outstanding or (b) the
    trust will not be required to register as an "investment company" under
    the 1940 Act.

   However, in the case described in the first bullet point above, the action
must not adversely affect in any material respect the interests of any holder
of preferred securities.

   For amendments not described above, the declaration of trust may only be
amended by us and the trustees if:

  . we obtain the consent of holders representing not less than a majority of
    the aggregate liquidation amount of preferred securities outstanding; and

  . the trustees receive an opinion of counsel that the amendment will not
    affect the trust's status as a grantor trust for United States federal
    income tax purposes or the trust's exemption from being an "investment
    company" under the 1940 Act.

   In addition, the declaration of trust may not be amended without the consent
of each holder of preferred securities to:

  . change or adversely affect the amount or timing of any distribution on
    the preferred securities; or

  . restrict the right of a holder of preferred securities to sue to enforce
    the payment of a distribution.

   So long as any debentures are held by the trust, the trustees will not:

  . direct the time, method and place of conducting any proceeding for any
    remedy available to the debenture trustee, or executing any trust or
    power conferred on the property trustee with respect to the debentures;

  . waive any past default that is waivable under the indenture;

  . exercise any right to rescind or annul a declaration of acceleration of
    the maturity of the principal of the debentures; or

  . consent to any amendment, modification or termination of the indenture or
    the debentures, where the consent is required,

without, in each case, obtaining the prior approval of the holders of a
majority in aggregate liquidation amount of all outstanding preferred
securities.

   However, where a consent under the indenture would require the consent of
each holder of debentures affected by the consent, no consent may be given by
the property trustee without the prior consent of each holder of the preferred
securities. The trustees will not revoke any action previously authorized or
approved by

                                       23
<PAGE>

a vote of the holders of the preferred securities except by subsequent vote of
the holders. The property trustee will notify each holder of preferred
securities of any notice of default with respect to the debentures. In addition
to obtaining the foregoing approvals of the holders of the preferred
securities, prior to taking any of the foregoing actions, the trustees will
obtain an opinion of counsel experienced in these matters that the action will
not affect the trust's status as a grantor trust for United States federal
income tax purposes on account of the action.

   Any required approval of holders of preferred securities may be given at a
meeting of the holders of preferred securities convened for that purpose or by
a written consent. Notice of any meeting at which holders of preferred
securities are entitled to vote will be given to each holder of record of
preferred securities in the manner set forth in the declaration of trust.

   No vote or consent of the holders of preferred securities will be required
for the trust to redeem and cancel the preferred securities in accordance with
the declaration of trust.

   Even though holders of the preferred securities may be entitled to vote or
consent under any of the circumstances described above, any of the preferred
securities that are owned by Hanover, the trustees or any affiliate of Hanover
or any trustee, will, for purposes of any vote or consent, be treated as if
they were not outstanding.

Expenses and Taxes

   In the indenture, we have agreed to pay all present and future costs,
expenses, debts and other obligations, including taxes, other than withholding
taxes, of the trust. However, these costs, expenses, debts and obligations do
not include payment obligations of the trust to the holders of the preferred
securities.

Form, Book-Entry Procedures and Transfer

   Preferred securities originally sold to "qualified institutional buyers" as
defined in Rule 144A under the Securities Act were issued in the form of a
fully registered global certificate except as described below. The global
certificate was deposited on the date of original issuance of the preferred
securities with DTC and registered in the name of Cede & Co., as nominee of
DTC. Except as set forth below, the global certificate may be transferred, in
whole and not in part, only to DTC or another nominee of the DTC. Investors may
hold their beneficial interests in the global certificate directly through DTC
if they have an account with DTC or indirectly through organizations that have
accounts with DTC.

   DTC has advised us as follows: DTC is a limited-purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities of institutions that have accounts with DTC ("participants") and to
facilitate the clearance and settlement of securities transactions among its
participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical
movement of securities certificates. DTC's participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. Access to DTC's book-entry system is also available to
others such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, whether directly or
indirectly.

   Upon the issuance of the global certificate, DTC credited, on its book-entry
registration and transfer system, the principal amount of the global
certificate to the accounts of participants. The accounts credited were
designated by the initial purchasers. Ownership of beneficial interests in the
global certificate is shown on, and the transfer of those ownership interests
will be effected only through, records maintained by DTC (with respect to its
participants) and such participants (with respect to owners of beneficial
interests in the global

                                       24
<PAGE>

certificate other than participants). The laws of some jurisdictions may
require that certain purchasers of securities take physical delivery of
securities in definitive form. These limits and laws may impair a person's
ability to transfer or pledge beneficial interests in the global certificate.

   So long as DTC or its nominee is the registered holder and owner of the
global certificate, DTC or its nominee, as the case may be, will be considered
the sole legal owner and holder of the preferred securities represented by the
certificate for all purposes of the declaration of trust, the guarantee and the
indenture. Except as described below, owners of beneficial interests in the
global certificate will not be entitled to have the preferred securities
represented by the global certificate registered in their names, will not
receive or be entitled to receive physical delivery of certificated preferred
securities in definitive form and will not be considered to be the owners or
holders of any preferred securities under the declaration of trust, the
guarantee or the indenture. We understand that under existing industry
practice, in the event an owner of a beneficial interest in the global
certificate desires to take any action that DTC, as the holder of the global
certificate, is entitled to take, DTC would authorize the participants to take
such action, and that the participants would authorize beneficial owners owning
through such participants to take such action or would otherwise act upon the
instructions of beneficial owners owning through them.

   Payment of amounts with respect to the preferred securities represented by
the global certificate registered in the name of and held by DTC or its nominee
will be made to DTC or its nominee, as the case may be, as the registered owner
and holder of the global certificate.

   We expect that DTC or its nominee, upon receipt of payment of amounts with
respect to the global certificate, will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the liquidation amount of the global certificate as shown on the records of DTC
or its nominee. We also expect that payments by participants to owners of
beneficial interests in the global certificate held through such participants
will be governed by standing instructions and customary practices and will be
the responsibility of such participants. Neither the trust, the initial
purchasers nor we will have any responsibility or liability for any aspect of
the records relating to, or payments made on account of, beneficial ownership
interests in the global certificate or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests or for
any other aspect of the relationship between or the relationship between such
participants and the owners of beneficial interests in DTC and its participants
or the relationship between such participants and the owners of beneficial
interests in the global certificate owning through such participants.

   Unless and to the extent they are exchanged in whole or in part for
certificated preferred securities in definitive form, the global certificate
may not be transferred except as a whole by DTC to a nominee of DTC or by a
nominee of DTC to DTC or another nominee of DTC.

   Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the global certificate among participants of DTC, it
is under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the trust, the initial
purchasers nor we will have any responsibility for the performance by DTC or
its participants or indirect participants of their respective obligations under
the rules and procedures governing their operations.

   Neither the trust, the initial purchasers, nor we will be liable for any
delay by DTC or any participant or indirect participant in identifying the
beneficial owners of the preferred securities, and we, the trust and the
initial purchasers may conclusively rely on, and will be protected in relying
on, instructions from DTC for all purposes (including with respect to the
registration and delivery, and their respective liquidation amounts, of the
preferred securities to be issued).

   The information in this prospectus concerning DTC and DTC's book-entry
system has been obtained from sources that we believe to be reliable. Neither
the trust, the initial purchasers nor we will have any responsibility for the
performance by DTC or its participants of their respective obligations as
described in this prospectus or under the rules and procedures governing their
respective operations.

                                       25
<PAGE>

 Certificated Preferred Securities

   The preferred securities represented by the global certificate are
exchangeable for certificated preferred securities in definitive form only if:

  . DTC notifies us or the trust that it is unwilling or unable to continue
    as depositary for the global certificate or if at any time DTC ceases to
    be a clearing agency registered under the Exchange Act;

  . we, or the trust, in our discretion at any time determine not to have all
    of the preferred securities evidenced by the global certificate; or

  . a default entitling the holders of the preferred securities to accelerate
    the maturity of the preferred securities has occurred and is continuing.

Payment and Paying Agency

   Payments in respect of the global certificate will be made to DTC. DTC will
credit the relevant accounts at DTC on the applicable distribution dates. For
any preferred securities that are not held by DTC, payment will be made by
check mailed to the address of the holder entitled to payment as the address
appears on the register. The paying agent will initially be the property
trustee. The paying agent will be permitted to resign upon 30 days' written
notice to the property trustee, the administrative trustees and us. In the
event that the property trustee is no longer willing to be the paying agent,
the administrative trustees will appoint a successor, which will be a bank or
trust company acceptable to the administrative trustees and to us, to act as
paying agent.

   The property trustee has informed the trust that so long as it serves as
paying agent for the preferred securities, it anticipates that information
regarding distributions on the preferred securities, including payment date,
record date and redemption information, will be made available through
Wilmington Trust Company.

Registrar, Conversion Agent, and Transfer Agent

   The property trustee acts as registrar and conversion agent for the
preferred securities. The property trustee acts as initial transfer agent for
certificated preferred securities and may designate additional or substitute
transfer agents at any time. Registration of transfers of certificated
preferred securities will be effected without charge by or on behalf of the
trust upon payment of any tax or other government charges that may be imposed
in relation to the transfer. The trust will not be required to register the
transfer of or exchange certificated preferred securities during the period
beginning at the opening of business 15 days before any selection of
certificated preferred securities to be redeemed and ending at the close of
business on the day of that selection or any certificated preferred securities
called for redemption.

Information Concerning the Property Trustee

   The property trustee, other than during the occurrence and continuance of an
event of default, undertakes to perform only the duties that are specifically
described in the declaration of trust. During the existence of an event of
default under the declaration of trust, the property trustee must exercise the
same degree of care and skill as a prudent person would exercise or use in the
conduct of his or her own affairs. Subject to this provision, the property
trustee is under no obligation to exercise any of the powers vested in it by
the declaration of trust at the request of any holder of preferred securities
unless it is offered reasonable indemnity against any costs, expenses and
liabilities that might be incurred by the property trustee. If no event of
default has occurred and is continuing and the property trustee is required to
decide between alternative causes of action, construe ambiguous provisions in
the declaration of trust or is unsure of the application of any provision of
the declaration of trust, and the matter is not one on which holders of the
preferred securities or the common securities are entitled under the
declaration of trust to vote, then the property trustee will take such action
as is directed by us. If we do not direct the property trustee to take action,
the property trustee will take the action that it deems advisable and in the
best interests of the holders of the preferred securities and common securities
and will have no liability except for its own bad faith, negligence or willful
misconduct.


                                       26

Miscellaneous

   The administrative trustees are authorized and directed to conduct the
affairs of and to operate the trust in such a way that:

  . the trust will not be deemed to be an "investment company" required to be
    registered under the 1940 Act;

  . the trust will not be classified as an association taxable as a
    corporation for United States federal income tax purposes or in a way
    that would substantially increase the risk that the trust would be
    classified as other than a grantor trust for United States federal income
    tax purposes; and

  . the debentures will be treated as our indebtedness for United States
    federal income tax purposes.

   In this connection, we and the administrative trustees are authorized to
take any action, not inconsistent with applicable law, the certificate of trust
or the declaration of trust, that we and the administrative trustees determine
in our discretion to be necessary or desirable for these purposes, as long as
the action does not materially adversely affect the interests of the holders of
the preferred securities and common securities. Holders of the preferred
securities and common securities have no preemptive or similar rights. The
trust may not borrow money or issue debt or mortgage or pledge any of its
assets.

Governing Law

   The declaration of trust and the preferred securities are governed by and
construed in accordance with the laws of the State of Delaware.

                                       27
<PAGE>

                           DESCRIPTION OF DEBENTURES

   We issued the debentures under an indenture between us and Wilmington Trust
Company, as trustee. The indenture will be qualified under the Trust Indenture
Act and incorporates selected provisions of the Trust Indenture Act. We have
summarized selected provisions of the indenture and the debentures. This
summary is not complete, and is subject to and is qualified in its entirety by
reference to all of the provisions of the indenture. A copy of indenture is
available upon request. Unless the context requires otherwise, "Hanover," "we,"
"us," "our" and similar terms in this section refer solely to Hanover
Compressor Company after giving effect to the Restructuring and not the trust
or any of our other consolidated subsidiaries.

General

   Concurrently with the issuance of the preferred securities and common
securities, the trust invested the proceeds in debentures issued by us. The
debentures bear interest at the rate of 7 1/4% per annum from December 15,
1999. Interest is payable quarterly in arrears on March 15, June 15, September
15 and December 15 of each year, beginning March 15, 2000, to the person in
whose name each debenture is registered, subject to certain exceptions, at the
close of business on the 1st day of the month of the applicable interest
payment date. It is anticipated that, until the liquidation of the trust, each
debenture will be registered in the name of the trust and held by the property
trustee for the benefit of the holders of the Preferred Securities and common
securities.

   The amount of interest payable for any period will be computed on the basis
of the number of days elapsed in a 360-day year consisting of twelve 30-day
months. If an interest payment date is not a business day, then we will make
the payment of the interest on the next day that is a business day, without any
additional interest or other payment due to the delay.

   Accrued interest that is not paid on the applicable interest payment date
will bear additional interest compounded quarterly from the relevant interest
payment date. The term "interest" as used in this prospectus includes quarterly
interest payments, interest on quarterly interest payments not paid on the
applicable interest payment date, special interest (as described in the
"Registration Rights" section of this prospectus) and additional sums (as
described in "--Additional Sums"), as applicable.

   Unless previously redeemed or repurchased in accordance with the indenture,
the debentures will mature on December 15, 2029.

   The debentures are unsecured and rank junior and are subordinate in right of
payment to all of our senior debt and effectively subordinated to all existing
and future liabilities of our subsidiaries, including HCI's bank credit
facility. The indenture does not limit the incurrence or issuance of other
secured or unsecured debt by us or any of our subsidiaries, including senior
debt.

Option to Extend Interest Payment Date

   We can, on one or more occasions, defer interest payments on the debentures
for up to 20 consecutive quarterly periods unless an event of default under the
indenture has occurred and is continuing. Thus, we will not be obligated to pay
interest on the debentures during a deferral period. We do not currently intend
to defer interest payments on the debentures.

   We may extend a deferral period prior to the period's termination. However,
we may not extend a deferral period, including all previous and further
extensions of the period, beyond 20 consecutive quarterly interest periods or
the maturity date of the debentures. On the interest payment date occurring at
the end of each deferral period, we will pay to the holders of debentures all
accrued and unpaid interest on the debentures, together with interest on that
interest at the stated annual rate, compounded quarterly, to the extent
permitted by applicable law. Once we make all interest payments due on the
debentures, we can commence a new deferral

                                       28
<PAGE>

period, subject to the same limitations. Consequently, there could be multiple
deferral periods of varying lengths throughout the term of the debentures.
During a deferral period, interest will continue to accrue and holders of the
debentures (and holders of the preferred securities while the preferred
securities are outstanding) will be required to recognize interest income for
United States federal income tax purposes. Please read the "Federal Income Tax
Consequences--Interest Income and Original Issue Discount" section of this
prospectus.

   We will be subject to restrictions during a deferral period on our ability
to pay dividends on our capital stock or to make payments on other debt
securities that are on a parity with or junior to the debentures. Please read
the "--Restrictions on Payments" section of this prospectus.

   We must give the property trustee, the administrative trustees and the
debenture trustee notice of our election to begin a deferral period at least 10
days before the record date for the distributions on the preferred securities
that would have been payable except for the election to begin or extend the
deferral period. The debenture trustee will give notice of our election to
begin or extend a new deferral period to the holders of the preferred
securities.

Redemption

 Repayment at Maturity; Redemption of Debentures

   The debentures must be repaid at their stated maturity, unless earlier
redeemed. The circumstances in which we may redeem the debentures prior to
their stated maturity are described below. Upon the repayment in full at
maturity or redemption (other than following the distribution of the debentures
to the holders of the preferred securities and common securities), the trust
will apply the proceeds from the repayment or redemption to redeem, at the
applicable redemption price, an equivalent liquidation amount of preferred
securities and common securities.

 Optional Redemption

   We have the right to redeem the debentures in whole or in part, at any time
on or after December 20, 2002, upon not less than 20 nor more than 60 days'
notice, at a redemption price equal to the following prices per $50 principal
amount of debentures, plus accrued and unpaid interest thereon, if redeemed
during the 12-month period ending December 19:

      2005.....................................................      $50.60
      2006 and thereafter......................................      $50.00
</TABLE>

   In the event of any redemption in part, we will not be required:

  . to issue, register the transfer of or exchange any debenture during a
    period beginning at the opening of business 15 days before any selection
    of debentures for redemption and ending at the close of business on the
    earliest date on which the notice of redemption is deemed to have been
    given to all holders of debentures to be redeemed; and

  . to register the transfer of or exchange any debentures selected for
    redemption, in whole or in part, except the unredeemed portion of any
    debenture being redeemed in part.

   In no event will we optionally redeem the debentures during a deferral
period. Accordingly, prior to optionally redeeming the debentures, all interest
accrued and unpaid (together, in the case of a deferral period,

                                       29
<PAGE>

with interest thereon, to the extent permitted by law) to the interest payment
date immediately preceding the optional redemption date will be paid in full.

 Tax Event Redemption

   We may also, under limited circumstances within 90 days of the occurrence
and continuation of a tax event, redeem the debentures in whole, but not in
part, at the aggregate principal amount of the debentures plus accrued and
unpaid interest on the debentures to the date of redemption. Please read the
"Description of Preferred Securities--Tax Event or Investment Company Event
Redemption or Distribution" section of this prospectus.

   If we are permitted to consummate the tax event redemption described above
and desire to do so, we must mail notice to holders of Preferred Securities at
least 20 days but not more than 60 days before the redemption date.

Additional Sums

   If the property trustee is the sole holder of all debentures and the trust
is required to pay any additional taxes, duties, assessments or other
governmental charges as a result of a tax event or otherwise, we will pay as
additional amounts on the debentures, referred to in this prospectus as
"additional sums", such amounts as are required so that the distributions
payable by the trust to holders of Preferred Securities and common securities
will not be reduced as a result of the additional taxes, duties, assessments or
other governmental changes.

Restrictions on Payments

   If any of the following occur:

  . an event of default under the indenture;

  . we are in default in our payment obligations under the guarantee; or

  . we have given notice of our election of a deferral period as provided in
    the indenture and have not rescinded the notice, or a deferral period is
    continuing,

then, we covenant that we will not:

  . declare or pay any dividends or distributions on, or redeem, purchase,
    acquire or make a liquidation payment with respect to, any of our capital
    stock other than stock dividends paid by us which consist of stock of the
    same class as that on which the dividend is being paid;

  . make any payment of principal, interest or premium, if any, on or repay
    or repurchase or redeem any of our debt securities that rank pari passu
    with or junior in interest to the debentures; or

  . make any guarantee payments with respect to any guarantee by us of the
    debt securities of any of our subsidiaries if the guarantee ranks pari
    passu with or junior in interest to the debentures.

   However, we may:

  . declare or pay dividends or distributions in our common stock;

  . declare a dividend in connection with the implementation of a
    stockholders' rights plan, or issue stock under the plan in the future,
    or redeem or repurchase the rights pursuant to the plan;

  . make payments under the guarantee;

  . purchase shares of our common stock in connection with the satisfaction
    by us of our obligations under any employee benefit plan or any other of
    our contractual obligations so long as they do not rank pari passu with
    or junior in interest to the debentures;

                                       30
<PAGE>

  . do any of the foregoing if it is a result of a reclassification of our
    capital stock or the exchange or conversion of one class or series of our
    capital stock for another class or series of our capital stock; or

  . purchase fractional interests in shares of our capital stock pursuant to
    the conversion or exchange provisions of that capital stock or the
    security being converted or exchanged.

Modification of Indenture

   From time to time we and the debenture trustee may, without the consent of
the holders of debentures, amend, waive or supplement the indenture for
specified purposes, including, among other things:

  . curing ambiguities, defects or inconsistencies (provided that any such
    action does not materially adversely affect the interest of the holders
    of debentures or the holders of the preferred securities so long as they
    remain outstanding); and

  . qualifying, or maintaining the qualification of, the indenture under the
    Trust Indenture Act.

   In addition, we and the debenture trustee, with the consent of the holders
of not less than a majority in principal amount of the outstanding debentures,
can modify the indenture in a manner affecting the rights of the holders of
debentures. However, without the consent of the holder of each affected
debenture, we may not:

  . change the stated maturity of the debentures;

  . reduce the principal amount of the debentures;

  . reduce the rate or extend the time of payment of interest on the
    debentures; or

  . reduce the percentage of principal amount of debentures the consent of
    whose holders is required to amend, waive or supplement the indenture, or
    have certain other effects as set forth in the indenture.

   notwithstanding the provisions described above or in the "--Events of
Default" section of this prospectus, so long as any of the preferred securities
remain outstanding, (a) no modification may be made that adversely affects the
holders of the preferred securities in any material respect, and no termination
of the indenture may occur, and no waiver of any event of default under the
indenture or compliance with any covenant under the indenture may be effective,
without the prior consent of the holders of at least a majority in aggregate
liquidation preference of preferred securities then outstanding unless and
until the principal of and any premium on the debentures and all accrued and
unpaid interest thereon has been paid in full and (b) where a consent under the
indenture would require the consent of each holder of debentures, no consent
will be given by the property trustee without the prior consent of each holder
of the preferred securities.

Events of Default

   The indenture provides that any one or more of the following described
events with respect to the debentures that has occurred and is continuing
constitutes an event of default under the indenture:

  . failure for 30 days to pay any interest on the debentures when due
    (subject to the deferral of any due date in the case of a deferral
    period);

  . failure to pay any principal or premium, if any, on the debentures when
    due, whether at maturity, upon redemption, by declaration of acceleration
    or otherwise;

  . failure to observe or perform certain other covenants contained in the
    indenture for 60 days after written notice to us from the debenture
    trustee or the holders of at least 25% in aggregate outstanding principal
    amount of the debentures;

  . our failure to issue and deliver shares of our common stock upon an
    election by a holder of preferred securities to convert such preferred
    securities;

  . certain events of bankruptcy, insolvency or reorganization of Hanover; or


                                       31
<PAGE>

  . the voluntary or involuntary dissolution, winding-up or termination of
    the trust, except in connection with the distribution of the debentures
    to the holders of preferred securities or common securities in
    liquidation of the trust, the redemption of all of the preferred
    securities and common securities of the trust, or certain mergers,
    consolidations or amalgamations, each as permitted by the declaration of
    trust.

   The holders of a majority in aggregate outstanding principal amount of the
debentures have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the debenture trustee. The debenture
trustee or the holders of not less than 25% in aggregate outstanding principal
amount of the debentures may declare the principal due and payable immediately
upon an event of default under the indenture and, should the debenture trustee
or the holders of debentures fail to make such declaration, the holders of at
least 25% in aggregate liquidation amount of the preferred securities will have
such right. The holders of a majority in aggregate outstanding principal amount
of the debentures may annul the declaration and waive the default if the
default (other than the non-payment of the principal of the debentures which
has become due solely by such acceleration) has been cured and a sum sufficient
to pay all matured installments of interest and principal due otherwise than by
acceleration has been deposited with the debenture trustee. Should the holders
of debentures fail to annul the declaration and waive the default, the holders
of a majority in aggregate liquidation amount of the preferred securities will
have the right.

   The holders of a majority in aggregate outstanding principal amount of the
debentures affected thereby may, on behalf of the holders of all the
debentures, waive any past default, except a default in the payment of
principal of (or premium, if any) or interest (unless the default has been
cured and a sum sufficient to pay all matured installments of interest and
principal due otherwise than by acceleration has been deposited with the
debenture trustee) or a default in respect of a covenant or provision which
under the indenture cannot be modified or amended without the consent of the
holder of each outstanding debenture. Should the holders of such debentures
fail to annul the declaration and waive such default, the holders of a majority
in aggregate liquidation amount of the preferred securities will have the
right. We are required to file annually with the debenture trustee a
certificate as to whether or not we are in compliance with all the conditions
and covenants applicable to us under the indenture.

   If an event of default under the indenture has occurred and is continuing,
the property trustee will have the right to declare the principal of and the
interest on the debentures, and any other amounts payable under the indenture,
to be due and payable and to enforce its other rights as a creditor with
respect to the debentures.

Enforcement of Certain Rights by Holders of Preferred Securities

   If an event of default under the indenture has occurred and is continuing
and is attributable to our failure to pay interest or principal on the
debentures on the date such interest or principal is otherwise payable, a
holder of preferred securities may institute a direct action against us. We may
not amend the indenture to remove the right to bring a direct action against us
without the prior written consent of the holders of all of the preferred
securities. Notwithstanding any payments made to a holder of preferred
securities by us in connection with a direct action against us, we will remain
obligated to pay the principal of and interest on the debentures, and will be
subrogated to the rights of the preferred securities holders with respect to
payments on the preferred securities to the extent of any payments made by us
to such holder in any direct action against us.

   The holders of the preferred securities will not be able to exercise
directly any remedies, other than those set forth in the preceding paragraph,
available to the holders of the debentures unless there is an event of default
under the declaration of trust.

Consolidation, Merger, Sale of Assets and Other Transactions

   The indenture provides that we may not consolidate with or merge with or
into any other person or convey, transfer or lease our properties and assets
substantially as an entirety to any person, and no person may consolidate with
or merge with or into us or convey, transfer or lease its properties and assets
substantially as an entirety to us, unless:

                                       32
<PAGE>

  . in case we consolidate with or merge with or into another person or
    convey or transfer our properties and assets substantially as an entirety
    to any person, the successor person is organized under the laws of the
    United States or any state of the United States or the District of
    Columbia, and the successor person expressly assumes our obligations on
    the debentures and provides for conversion rights in accordance with the
    terms of the indenture;

  . immediately after giving effect to the transaction, no event of default
    under the indenture, and no event which, after notice or lapse of time or
    both, would become an event of default under the indenture, will have
    occurred and be continuing;

  . if at the time any preferred securities are outstanding, the transaction
    is permitted under the declaration of trust and the guarantee and does
    not give rise to any breach or violation of the declaration of trust or
    the guarantee; and

  . other conditions as specified in the indenture are met.

   The general provisions of the indenture do not afford holders of the
debentures protection in the event of a highly leveraged or other transaction
involving us that may adversely affect holders of the debentures.

Subordination

   In the indenture, we have covenanted and agreed that the debentures will be
subordinate and junior in right of payment to all our senior debt to the extent
provided in the indenture. Upon any payment or distribution of assets to
creditors upon any liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors, marshaling of assets or any
bankruptcy, insolvency, debt restructuring or similar proceedings in connection
with any insolvency or bankruptcy proceeding of us, the holders of our senior
debt will first be entitled to receive payment in full before the holders of
debentures will be entitled to receive or retain any payment.

   If the maturity of the debentures is accelerated, the holders of all our
senior debt outstanding at the time of the acceleration will be entitled to
receive payment in full of all amounts due on the senior debt, including any
amounts due upon acceleration, before the holders of the debentures will be
entitled to receive or retain any payment of the principal of, and premium and
interest, if any, on, the debentures.

   In the event that we default in the payment of any principal of, or premium
or interest on, any of our senior debt, and such default continues beyond the
period of grace, if any, specified in the instrument evidencing the senior
debt, then, unless and until the default is cured or waived or ceases to exist
or all senior debt is paid, no direct or indirect payment may be made or agreed
to be made for principal of, and premium and interest, if any, on, the
debentures, or in respect of any redemption, repayment, retirement, purchase or
other acquisition of any of the debentures.

   The term "senior debt" as used in this prospectus means:

  . the principal of, and premium and interest, if any, on all of our
    indebtedness for money borrowed, whether outstanding on the date of
    execution of the indenture or thereafter created, assumed or incurred;

  . all obligations to make payment pursuant to the terms of financial
    instruments, such as (1) securities contracts and foreign currency
    exchange contracts, (2) derivative instruments, such as swap agreements
    (including interest rate and foreign exchange rate swap agreements), cap
    agreements, floor agreements, collar agreements, interest rate
    agreements, foreign exchange agreements, options, commodity futures
    contracts and commodity options contracts, and (3) similar financial
    instruments; except, in the case of both the immediately preceding bullet
    point and this bullet point, the indebtedness and obligations that are
    expressly stated to rank junior in right of payment to, or pari passu in
    right of payment with, the debentures;

                                       33
<PAGE>

  . indebtedness or obligations of others of the kind described in the two
    immediately preceding bullet points above for the payment of which we are
    responsible or liable as guarantor or otherwise; and

  . any deferrals, renewals or extensions of such senior debt.

   However, senior debt does not include:

  . any of our debt which, when incurred and without respect to any election
    under Section 1111(b) of the United States Bankruptcy Code of 1978, was
    without recourse to us;

  . trade accounts payable and accrued liabilities arising in the ordinary
    course of business;

  . any of our debt to any of our subsidiaries;

  . debt to any of our employees; and

  . debt which by its terms is subordinated to trade accounts payable or
    accrued liabilities arising in the ordinary course of business to the
    extent that payments made to the holders of such debt by the holders of
    the debentures as a result of the subordination provisions of the
    indenture would be greater than such payments otherwise would have been
    as a result of any obligation of such holders of such debt to pay amounts
    over to the obligees on such trade accounts payable or accrued
    liabilities arising in the ordinary course of business as a result of
    subordination provisions to which such debt is subject.

   The term "debt" as used in this prospectus means:

  . the principal of, and premium and interest, if any, on, indebtedness for
    money borrowed;

  . purchase money and similar obligations;

  . obligations under capital leases;

  . guarantees, assumptions or purchase commitments relating to, or other
    transactions as a result of which we are responsible for the payment of
    such indebtedness of others;

  . renewals, extensions and refunding of any such indebtedness;

  . interest or obligations in respect of any such indebtedness accruing
    after the commencement of any insolvency or bankruptcy proceedings; and

  . obligations associated with derivative products such as interest rate and
    currency exchange contracts, foreign exchange contracts, commodity
    contracts and similar arrangements.

   The indenture places no limitation on the amount of senior debt that we or
our subsidiaries may incur. At October 31, 1999 after giving effect to the
restructuring, we had no senior debt but had guaranteed approximately $122
million of HCI's indebtedness under its bank credit agreement. In addition, we
had guaranteed the residual value of the equipment under HCI's sale and lease
back transactions of approximately $332 million, which guarantee ranks senior
to the debentures.

Structural Subordination

   The debentures are effectively junior in right of payment to all of our
subsidiaries' existing or future indebtedness and other liabilities. As of
October 31, 1999 after giving effect to the Restructuring, our subsidiaries had
$146 million of indebtedness. The indenture permits our subsidiaries to incur
indebtedness and other liabilities without restriction. Any indebtedness of our
subsidiaries will effectively rank senior to the debentures with respect to
such subsidiary's assets. Accordingly, there might only be a limited amount of
assets available to satisfy Hanover's obligations under the debentures and, as
a result, the trust's obligations to holders of the preferred securities.

   The debentures and the guarantee are obligations exclusively of Hanover.
Since the operations of Hanover are conducted through its subsidiaries, the
cash flow and the consequent ability to service debt, including the

                                       34
<PAGE>

debentures and the guarantee, of Hanover, are dependent upon the earnings of
its subsidiaries and the distribution of those earnings to, or upon loans or
other payments of funds by those subsidiaries to, Hanover.

   The payment of dividends and the making of loans and advances to Hanover by
its subsidiaries may be subject to statutory or contractual restrictions, are
dependent upon the earnings of those subsidiaries and are subject to various
business considerations.

   Any right of Hanover to receive assets of any of its subsidiaries upon their
liquidation or reorganization (and the consequent right of the holders of the
debentures to participate in those assets) will be effectively subordinated to
the claims of that subsidiary's creditors (including trade creditors), except
to the extent that Hanover is itself recognized as a creditor of such
subsidiary, in which case the claims of Hanover would still be subordinate to
any security interests in the assets of such subsidiary and any indebtedness of
such subsidiary senior to that held by Hanover.

Registration and Transfer

   The debentures will be represented by one or more global certificates
registered in the name of Cede & Co. as the nominee of DTC if, and only if,
distributed to the holders of the preferred securities and the trust's common
securities. Until that time, the debentures will remain registered in the name
of and held by the property trustee. Should the debentures be distributed to
holders of the preferred securities and the trust's common securities,
beneficial interests in the debentures will be shown on, and transfers of
debentures will be effected only through, records maintained by participants in
DTC. Except as described below, debentures in certificated form will not be
issued in exchange for the global certificates.

   A global security will be exchangeable for debentures in certificated form
registered in the names of persons other than Cede & Co. only if:

  . DTC notifies us that it is unwilling or unable to continue as a
    depositary for the global security or if at any time DTC ceases to be a
    clearing agency registered under the Exchange Act;

  . we in our sole discretion determine that the global security will be
    exchangeable; or

  . there shall have occurred and be continuing an event of default under the
    indenture.

   Payments on debentures held in global form will be made to DTC. For
debentures issued in certificated form, principal and interest will be payable,
the transfer of the debentures will be registrable, and debentures will be
exchangeable for debentures of other denominations of a like aggregate
principal amount, at the corporate office of the debenture trustee in New York,
New York, or at the offices of any paying agent or transfer agent appointed by
us, provided that payment of interest may be made at our option by check mailed
to the address of the persons entitled to payment or by wire transfer.

   For a description of DTC and the terms of the depositary arrangements
relating to payments, transfers, voting rights, redemptions and other notices
and other matters, please read the "Description of Preferred Securities--Form,
Book-Entry Procedures and Transfer" section of this prospectus. If the
debentures are distributed to the holders of the Preferred Securities and
common securities upon the termination of the trust, the form, book-entry and
transfer procedures with respect to the Preferred Securities as described under
the "Description of Preferred Securities--Form, Book-Entry Procedures and
Transfer" section of this prospectus will apply to the debentures.

Payment and Paying Agents

   Payment of the principal of, and premium and interest, if any, on, the
debentures will be made at the office or agency of us maintained for that
purpose in New York, New York, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. However, at our option, payment of interest may be made (except
in the case of debentures that are held in global form)

                                       35
<PAGE>

by check mailed to each registered holder or by wire transfer. Payment of any
interest on any debenture will be made to the person in whose name the
debenture is registered at the close of business on the record date for such
interest, except in the case of defaulted interest.

Governing Law

   The indenture and the debentures are governed by and construed in accordance
with the laws of the State of New York.

Information Concerning the Debenture Trustee

   The debenture trustee has and is subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the debenture trustee is under no
obligation to exercise any of the powers vested in it by the indenture at the
request of any holder of debentures, unless offered reasonable indemnity by the
holder against the costs, expenses and liabilities that might be incurred by
the debenture trustee. The debenture trustee is not required to expend or risk
its own funds or otherwise incur personal financial liability in the
performance of its duties if the debenture trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.

                            DESCRIPTION OF GUARANTEE

   The guarantee was executed and delivered by us concurrently with the
issuance by the trust of the preferred securities for the benefit of holders of
preferred securities. Wilmington Trust Company acts as trustee under the
guarantee agreement. The guarantee agreement will be qualified under the Trust
Indenture Act. We have summarized selected provisions of the guarantee
agreement. This summary is not complete and is subject to, and qualified in its
entirety by reference to, all of the provisions of the guarantee agreement. The
guarantee trustee will hold the guarantee for the benefit of the holders of the
preferred securities. A copy of the guarantee agreement is available upon
request. Unless the context requires otherwise, "Hanover," "we," "us," "our"
and similar terms in this section refer solely to Hanover Compressor Company
after giving effect to the Restructuring and not the trust or any of our other
consolidated subsidiaries.

General

   Under the guarantee agreement, we irrevocably agree to pay in full on a
subordinated basis, to the extent described below, the guarantee payments
described below to the holders of the preferred securities regardless of any
defense, right of set-off or counterclaim that the trust may have or assert
other than the defense of payment. The following payments, called the guarantee
payments, with respect to the preferred securities, to the extent not paid by
or on behalf of the trust, will be subject to the guarantee:

  . any accrued and unpaid distributions required to be paid on the preferred
    securities, to the extent that the trust has funds on hand available for
    payment at such time;

  . the applicable redemption price with respect to preferred securities
    called for redemption, to the extent that the trust has funds on hand
    available for payment at such time; and

  . upon a voluntary or involuntary dissolution, winding up or liquidation of
    the trust, other than in connection with the distribution of debentures
    to the holders of the preferred securities or the redemption of all of
    the preferred securities, the lesser of:

    .the liquidation distribution, to the extent the trust has funds
       available therefor; and

    . the amount of assets of the trust remaining available for distribution
      to holders of the preferred securities upon liquidation of the trust
      after satisfaction of liabilities to creditors of the trust as
      required by applicable law.

   Our obligation to make a guarantee payment may be satisfied by direct
payment of the required amounts by us to the holders of the preferred
securities or by causing the trust to pay the amounts to the holders.

   The guarantee is an irrevocable guarantee on a subordinated basis of the
trust's obligations under the preferred securities. However, the guarantee will
apply only to the extent that the trust has funds sufficient to make such
payments, and is not a guarantee of collection. If we do not make interest
payments on the debentures held by the trust, the trust will not be able to pay
distributions on the preferred securities and will not have funds legally
available for the distributions.

   The guarantee ranks subordinate and junior in right of payment to all senior
debt. In addition, our obligations under the guarantee are effectively
subordinated to all existing and future liabilities of our subsidiaries. The
guarantee does not limit the incurrence or issuance of other secured or
unsecured debt by us or by our subsidiaries, including senior debt.

   Taken together, our obligations under the guarantee agreement, the
declaration of trust, the debentures and the indenture, including our
obligation to pay the costs, expenses and other liabilities of the trust other
than the trust's obligations to the holders of the preferred securities and
common securities, provide, in the aggregate, a full, irrevocable and
unconditional guarantee of all of the trust's obligations under the preferred
securities. No single document standing alone or operating in conjunction with
fewer than all the other documents constitutes

                                       37
<PAGE>

such guarantee. It is only the combined operation of these documents that has
the effect of providing a full, irrevocable and unconditional guarantee of the
trust's obligations under the preferred securities.

Status of the Guarantee

   The guarantee is a guarantee of payment and not of collection, meaning the
guaranteed party may institute a legal proceeding directly against us to
enforce its rights under the guarantee without first instituting a legal
proceeding against any other person or entity. The guarantee will be held for
the benefit of the holders of the preferred securities. The guarantee will not
be discharged except by payment of the guarantee payments in full to the extent
not paid by the trust or upon distribution to the holders of the preferred
securities of the debentures.

Amendments and Assignment

   Except with respect to any changes that do not materially adversely affect
the rights of holders of the preferred securities (in which case no vote will
be required), the guarantee may not be amended without the prior approval of
the holders of not less than a majority of the aggregate liquidation amount of
the outstanding preferred securities. The manner of obtaining any such approval
will be as set forth under the "Description of preferred securities--Voting
Rights; Amendment of the Declaration" section of this prospectus. All
guarantees and agreements contained in the guarantee will bind the successors,
assigns, receivers, trustees and our representatives and will inure to the
benefit of the holders of the preferred securities then outstanding.

Events of Default

   An event of default under the guarantee will occur upon our failure to
perform any of our payment or other obligations under the guarantee agreement.
However, except for a failure to make a guarantee payment, we are entitled to
receive notice of the default and cure the default within 60 days after receipt
of the notice. The holders of a majority in aggregate liquidation amount of the
preferred securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the guarantee trustee in
respect of the guarantee or to direct the exercise of any trust or power
conferred upon the guarantee trustee under the guarantee.

   Any holder of the preferred securities may institute a legal proceeding
directly against us to enforce its rights under the guarantee without first
instituting a legal proceeding against the trust, the guarantee trustee or any
other person or entity.

   We, as guarantor, are required to file annually with the guarantee trustee a
certificate as to whether or not we are in compliance with all the conditions
and covenants applicable to us under the guarantee.

Information Concerning the Guarantee Trustee

   The guarantee trustee, other than during the occurrence and continuance of a
default by us in performance of the guarantee, undertakes to perform only the
duties that are specifically described in the guarantee. After a default under
the guarantee agreement, the guarantee trustee must exercise the same degree of
care and skill as a prudent person would exercise or use in the conduct of his
or her own affairs. Subject to this provision, the guarantee trustee is under
no obligation to exercise any of the powers vested in it by the guarantee at
the request of any holder of the preferred securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred.

Termination of the Guarantee

   The guarantee will terminate as to each holder of preferred securities upon:

  . full payment of the redemption price and accrued and unpaid distributions
    with respect to all preferred securities;

                                       38
<PAGE>

  . distribution of the debentures held by the trust to the holders of the
    preferred securities;

  . liquidation of the trust; or

  . distribution of our common stock to such holder in respect of the
    conversion of such holder's preferred securities into common stock.

   In addition, the guarantee will terminate completely upon full payment of
the amounts payable in accordance with the declaration of trust. The guarantee
will continue to be effective or will be reinstated, as the case may be, if at
any time any holder must restore payment of any sums paid under the preferred
securities or the guarantee.

Governing Law

   The guarantee agreement is governed by and construed in accordance with the
laws of the State of New York.

                                       39

                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
                        THE DEBENTURES AND THE GUARANTEE

Full and Unconditional Guarantee

   Payments of distributions and other amounts due on the preferred securities
(to the extent the trust has funds available for the payment of such
distributions) are irrevocably guaranteed by us to the extent set forth under
the "Description of Guarantee" section of this prospectus. Taken together, our
obligations under the debentures, the indenture, the declaration of trust and
the guarantee agreement provide a full, irrevocable and unconditional guarantee
of payments of distributions and other amounts due on the preferred securities.
No single document standing alone or operating in conjunction with fewer than
all of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the trust's obligations under the
preferred securities. If and to the extent that we do not make payments on the
debentures, the trust will not pay distributions or other amounts due on the
preferred securities. The guarantee does not cover payment of distributions
when the trust does not have sufficient funds to pay such distributions. In
such event, the remedy of a holder of preferred securities is to institute a
direct action against us under the debentures. Our obligations under the
guarantee are subordinate and junior in right of payment to all our senior
debt. Unless the context requires otherwise, "Hanover," "we," "us," "our" and
similar terms in this section refer solely to Hanover Compressor Company after
giving effect to the Restructuring and not the trust or any of our other
consolidated subsidiaries.

Sufficiency of Payments

   As long as payments of interest and other payments are made when due on the
debentures, the payments will be sufficient to cover distributions and other
payments due on the preferred securities, primarily because:

  . the aggregate principal amount or applicable redemption price of the
    debentures will be equal to the sum of the aggregate liquidation amount
    or applicable redemption price, as applicable, of the preferred
    securities and common securities;

  . the interest rate payable on the debentures and interest and other
    payment dates on the debentures will match the distribution rate and
    distribution and other payment dates for the preferred securities;

  . we will pay for all costs, expenses and liabilities of the trust except
    the trust's obligations to holders of preferred securities and common
    securities; and

  . the declaration of trust further provides that the trust will not engage
    in any activity that is not consistent with its limited purposes.

   Notwithstanding anything to the contrary in the indenture, we have the right
to set off any payment we are otherwise required to make under the indenture to
the extent we have made, or are concurrently on the date of such payment
making, any payment under the guarantee used to satisfy the related payment of
indebtedness under the indenture.

Enforcement Rights of Holders of Preferred Securities

   Any holder of preferred securities may institute a legal proceeding directly
against us to enforce its rights under the guarantee without first instituting
a legal proceeding against the guarantee trustee, the trust or any other person
or entity and may, under certain circumstances, also institute a legal
proceeding directly against us to recover unpaid amounts under the debentures.

   A default or event of default under any of our senior debt would not
constitute a default or event of default under the declaration of trust.
However, in the event of payment defaults under, or acceleration of, our senior
debt, the subordination provisions of the indenture provide that no payments
may be made in respect of the debentures until the senior debt has been paid in
full or any payment default thereunder has been cured or waived. Failure to
make required payments on debentures would constitute an event of default under
the declaration of trust.

                                       40
<PAGE>

Limited Purpose of the Trust

   The preferred securities evidence a beneficial interest in the trust, and
the trust exists for the sole purpose of issuing the preferred securities and
common securities and investing the proceeds of the preferred securities and
common securities in debentures.

Rights Upon Dissolution

   Upon any voluntary or involuntary dissolution, winding-up or liquidation of
the trust involving the liquidation of the debentures, after satisfaction of
the liabilities of creditors of the trust as required by applicable law, the
holders of the preferred securities and common securities will be entitled to
receive, out of assets held by the trust, the liquidation distribution in cash.
Upon any voluntary or involuntary liquidation or our bankruptcy, the property
trustee, as holder of the debentures, would be a subordinated creditor of us,
subordinated in right of payment to all senior debt as set forth in the
indenture, but entitled to receive payment in full of principal and interest,
before any of our stockholders receive payments or distributions. Since we are
the guarantor under the guarantee and have agreed to pay for all costs,
expenses and liabilities of the trust, other than the trust's obligations to
the holders of the preferred securities and common securities, the positions of
a holder of preferred securities and a holder of debentures relative to other
creditors and to our stockholders in the event of liquidation or our bankruptcy
are expected to be substantially the same.

                      DESCRIPTION OF HANOVER CAPITAL STOCK

   Our authorized capital stock currently consists of 100,000,000 shares of
common stock and 3,000,000 shares of preferred stock, $.01 par value per share.
The following summary description relating to the capital stock does not
purport to be complete. For a detailed description, reference is made to our
certificate of incorporation.

Common Stock

   As of November 30, 1999, 28,674,267 shares of common stock were issued and
held of record by approximately 236 stockholders. The holders of common stock
are entitled to one vote for each share held of record on all matters submitted
to a vote of the stockholders. Subject to preferential rights with respect to
our preferred stock, holders of common stock are entitled to receive ratably
any dividends declared by our board of directors out of legally available
funds. On liquidation, dissolution, sale or winding up of Hanover, holders of
common stock are entitled to share ratably in all assets remaining after
payment of liabilities and satisfaction of preferential rights. Holders of
common stock have no preemptive or subscription rights. The outstanding shares
of common stock are, and the shares of common stock to be issued upon
conversion of the preferred securities will be, fully paid and nonassessable.
We have never declared a dividend on the common stock, and our bank credit
agreement prohibits the payment of dividends on common stock without the
lenders' prior written consent. The payment of any such dividends also will be
subject to, and may be limited by, the terms of any preferred stock we may
issue in the future.

Transfer Agent And Registrar

   The transfer agent and registrar for the common stock is ChaseMellon
Shareholder Services.

Preferred Stock

   We are authorized to issue 3,000,000 shares of preferred stock. Our board of
directors may establish, without stockholder approval, one or more classes or
series of preferred stock having the number of shares, designations, relative
voting rights, dividend rates, liquidation and other rights, preferences and
limitations that the board of directors may designate. We believe that this
power to issue preferred stock provides flexibility in connection with possible
corporate transactions. The issuance of preferred stock, however, could
adversely affect the voting power of holders of common stock and restrict their
rights to receive payments upon liquidation of Hanover. It could also have the
effect of delaying, deferring or preventing a change in control of Hanover.

Special Provisions Of The Certificate Of Incorporation And Delaware Law

   Section 102(b)(7) of the Delaware General Corporation Law authorizes
corporations to limit or eliminate the personal liability of directors to
corporations and their stockholders for monetary damages for breach of
directors' fiduciary duty of care. Although Section 102(b) does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. Our certificate of
incorporation limits the liability of directors to us or our stockholders (in
their capacity as directors but not in their capacity as officers) to the
fullest extent permitted by Section 102(b). Specifically, our directors will
not be personally liable for monetary damages for breach of a director's
fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to Hanover or our stockholders (b) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) for unlawful payments of dividends or unlawful
stock repurchases or redemptions as provided in Section 174 of the Delaware
General Corporation Law or (d) for any transaction from which the director
derived an improper personal benefit.

   To the maximum extent permitted by law, our certificate of incorporation and
bylaws provide for mandatory indemnification of directors and officers and
permit indemnification of our officers, employees and

                                       42
<PAGE>

agents against all expense, liability and loss to which they may become subject
or which they may incur as a result of being or having been a director,
officer, employee or agent of Hanover or its subsidiaries. In addition, we must
advance or reimburse directors, and may advance or reimburse officers,
employees and agents for expenses incurred by them in connection with
indemnifiable claims.

   We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, Section 203 prohibits a public Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless (a) before that
person became an interested stockholder, the corporation's board of directors
approved the transaction in which the interested stockholder became an
interested stockholder or approved the business combination; (b) upon
completion of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owns at least
85% of the voting stock outstanding at the time the transaction commenced
(excluding stock held by directors who are also officers of the corporation and
by employee stock plans that do not provide employees with the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer); or (c) following the transaction in
which that person became an interested stockholder, the business combination is
approved by the corporation's board of directors and authorized at a meeting of
stockholders by the affirmative vote of the holders of at least two-thirds of
the outstanding voting stock not owned by the interested stockholder. Under
Section 203, these restrictions also do not apply to certain business
combinations proposed by an interested stockholder following the announcement
or notification of one of certain extraordinary transactions involving the
corporation and a person who was not an interested stockholder during the
previous three years or who became an interested stockholder with the approval
of a majority of the corporation's directors, if that extraordinary transaction
is approved or not opposed by a majority of the directors who were directors
before any person became an interested stockholder in the previous three years
or who were recommended for election or elected to succeed such directors by a
majority of such directors then in office. "Business combination" includes
mergers, assets sales and other transactions resulting in a financial benefit
to the stockholder. "Interested stockholder" is a person who, together with
affiliates and associates, owns (or within three years, did own) 15% or more of
the corporation's voting stock.

                        FEDERAL INCOME TAX CONSEQUENCES

   In the opinion of Latham & Watkins, counsel to Hanover, the following are
the material United States federal income tax consequences to beneficial owners
resulting from their ownership and disposition of the preferred securities.
Unless otherwise stated, this summary considers only preferred securities and
common stock held as capital assets (generally, property held for investment).
The tax treatment of a holder may vary depending on its particular situation.
This summary does not consider all aspects of taxation that may be relevant to
a holder in light of its particular circumstances or to classes of holders who
are subject to special treatment under the federal income tax laws, including,
without limitation:

  . banks, thrifts, and other financial institutions;

  . real estate investment trusts and regulated investment companies;

  . insurance companies;

  . tax exempt organizations;

  . broker-dealers;

  . persons holding preferred securities or common stock as part of a
    straddle or as part of a hedging or conversion transaction or other
    integrated investment;

  . foreign persons; and

  . persons whose functional currency is not the United States dollar.

   In addition, this summary does not include any discussion of the alternative
minimum tax consequences or the tax laws of any state, local or foreign
jurisdictions that may be applicable to the preferred securities and the common
stock.

   This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury Regulations thereunder and administrative and judicial
interpretations thereof as of the date hereof, all of which are subject to
change, possibly on a retroactive basis. The authorities on which this summary
is based are subject to various interpretations, and it is therefore possible
that the federal income tax treatment of the ownership and disposition of
preferred securities and the common stock may differ from the treatment
described below. Neither the trust nor Hanover has sought, nor will either
seek, a ruling from the Internal Revenue Service (the "IRS") on the federal tax
consequences described in this summary, and it is possible that the IRS could
take a position contrary to the interpretations herein.

   Investors are advised to consult their own tax advisors as to the tax
consequences of the ownership and disposition of the preferred securities and
the common stock, in light of their particular circumstances, under the federal
income tax laws and any applicable state, local, foreign and other tax laws,
including the effects of possible future changes in such laws.

Classification of the Trust

   Assuming full compliance with the terms of the declaration of trust, the
indenture and certain other documents, the trust will be classified for federal
income tax purposes as a grantor trust and not as a corporation or a publicly
traded partnership taxable as a corporation. Accordingly, each holder of
preferred securities will be considered to be the owner of an undivided
interest in the debentures held by the trust and will be required to include in
gross income its pro rata share of interest income on the debentures, including
original issue discount (if any), whether or not cash is actually distributed
to the holder.

Classification of the Debentures

   Hanover intends to take the position that the debentures will be classified
for federal income tax purposes as indebtedness. By acceptance of the preferred
securities, each holder covenants to treat the debentures as

                                       44
<PAGE>

indebtedness and the preferred securities as evidence of an indirect beneficial
ownership interest in the debentures. No assurance can be given, however, that
the classification of the debentures as indebtedness will not be challenged by
the IRS or, if challenged, that such a challenge will not be successful. The
remainder of this summary assumes that the debentures will be classified for
federal income tax purposes as indebtedness of Hanover.

Interest Income and Original Issue Discount

   Unless the original issue discount ("OID") rules apply to the debentures, as
discussed below, stated interest on the preferred securities generally will be
taxable to a holder as ordinary income when paid or accrued in accordance with
the holder's method of accounting for federal income tax purposes. While the
existence of an issuer's option to defer the payment of interest on debt
instruments generally results in the application of the OID rules, debt
instruments like the debentures are not considered issued with OID if there is
only a "remote" likelihood of the issuer exercising its option of deferral.

   Hanover believes that, as of the issue date of the preferred securities, the
likelihood of Hanover deferring payments of interest under the terms of the
debentures was "remote" within the meaning of the applicable Treasury
Regulations. Therefore, the debentures should not be treated as subject to the
OID rules at the time of their original issuance by reason of Hanover's
deferral option.

   If the likelihood of Hanover exercising its option to defer any payment of
interest was determined not to be "remote" or if Hanover does exercise its
option to defer payments of interest, the debentures would be treated as
subject to the OID rules at the time of their original issuance or at the time
of such exercise, as the case may be, for the entire remaining term of the
debentures. Under these rules, all of the stated interest on the debentures
would be treated as OID and such OID would accrue, and be includible in income,
on a daily basis under a constant yield method, including during any interest
deferral period, regardless of the holder's method of accounting for federal
income tax purposes. Consequently, holders of the preferred securities would be
required to include OID in gross income even if Hanover did not make any actual
distributions during a deferral period. Actual distributions of stated interest
on the debentures generally would not be separately taxable. A holder that
disposes of its preferred securities prior to the record date for payment of
distributions on the debentures will be subject to tax on OID accrued through
the date of disposition and not previously included in income, but will not
receive cash from the trust with respect to such OID. If Hanover exercises its
deferral option, investors should consult their own tax advisors regarding
their specific tax consequences of such deferral.

   The income underlying the preferred securities should be treated as interest
and will not be characterized as dividends for federal income tax purposes.
Consequently, corporate holders of the preferred securities should not be
entitled to a dividends-received deduction for any income recognized with
respect to the preferred securities.

Market Discount

   The market discount rules generally provide that, subject to a statutorily-
defined de minimis exception, if an investor acquires a preferred security at a
market discount (i.e., at a price below its stated redemption price at maturity
or its revised issue price if it is subject to the OID rules) and thereafter
recognizes gain upon a disposition of the preferred security (or disposes of it
in certain non-recognition transactions such as a gift), the lesser of (i) such
gain (or appreciation, in the case of an applicable non-recognition
transaction) or (ii) the portion of the market discount that accrued while the
preferred security was held by such holder will be treated as ordinary interest
income at the time of the disposition. A holder of a preferred security who
acquired the preferred security at a market discount would be required to treat
as ordinary interest income the portion of any principal payment (including a
payment on maturity) attributable to accrued market discount on such preferred
security. In addition, a holder of a preferred security who acquires a
preferred security at a market discount

                                       45
<PAGE>

may be required to defer a portion of any interest expense that otherwise may
be deductible on any indebtedness incurred or maintained to purchase or carry
the preferred security until such holder disposes of the preferred security in
a taxable transaction.

   A holder of a preferred security who acquired a preferred security at a
market discount may elect to include market discount in income as the discount
accrues, either on a ratable basis or, if elected, on a constant interest rate
basis. The current inclusion election, once made, applies to all market
discount obligations acquired on or after the first day of the first taxable
year to which the election applies, and may only be revoked with the consent of
the IRS. If a holder makes a current inclusion election, the foregoing rules
with respect to the recognition of ordinary income on sales, principal payments
and certain other dispositions of the preferred securities and the deferral of
interest deductions on indebtedness related to the preferred securities would
not apply.

Amortizable Bond Premium

   Generally, if the price or tax basis of a preferred security exceeds the sum
of all amounts payable on the preferred security after the acquisition date
(other than payments of qualified stated interest), such excess may constitute
amortizable bond premium that a holder may elect to amortize under the constant
interest rate method over the period from the holder's acquisition date to the
maturity date of the preferred security. Amortizable bond premium generally
will be treated as an offset to interest income on a preferred security, rather
than as a separate interest deduction item subject to the investment interest
limitations of the Code. A holder of a preferred security that elects to
amortize bond premium must generally reduce the tax basis in the preferred
security by the amount of bond premium used to offset interest income. If a
preferred security purchased at a premium is redeemed in full prior to its
maturity, a holder of a preferred security who has elected to amortize bond
premium may be entitled to a deduction for any remaining unamortized bond
premium in the taxable year of redemption.

Sale of Preferred Securities

   A holder who sells preferred securities will be considered to have disposed
of all or part of its pro rata share of the debentures and will recognize gain
or loss equal to the difference between the amount realized on the sale of the
preferred securities and the holder's adjusted tax basis in such preferred
securities. A holder's adjusted tax basis in the preferred securities generally
will be its initial purchase price. If, however, the OID rules apply to the
debentures, a holder's adjusted tax basis in the preferred securities will be
its initial purchase price, increased by any OID or market discount previously
includible in such holder's income to the date of sale and decreased by
distributions or other payments received on the preferred securities from and
including the day that the debentures became subject to the OID rules and by
the amount of amortizable bond premium that offset interest income. Any gain or
loss recognized on the sale of the preferred securities generally will be
capital gain or loss except to the extent of any accrued interest with respect
to such holder's pro rata share of the debentures required to be included in
income as ordinary income. Such capital gain or loss will be long-term capital
gain or loss if the preferred securities have been held by the holder for more
than one year.

   If the debentures are subject to the OID rules, a holder who disposes of its
preferred securities between record dates for payments of distributions thereon
will be required to include OID on the debentures through the date of
disposition in income as ordinary income, and to add such amount to its
adjusted tax basis in the preferred securities. To the extent the amount
realized on the sale is less than the holder's adjusted tax basis, which basis
will include all accrued but unpaid OID, a holder will recognize a capital
loss. Subject to certain limited exceptions, capital losses cannot be applied
to offset ordinary income for federal income tax purposes.

Receipt of Debentures or Cash Upon Liquidation of the Trust

   Under certain circumstances, the debentures may be distributed to holders in
exchange for the preferred securities and in liquidation of the trust. Such a
distribution would be a nontaxable event to each holder, and each holder would
receive an aggregate tax basis in the debentures equal to such holder's
aggregate tax basis in

                                       46
<PAGE>

the preferred securities. A holder's holding period in the debentures so
received would include the period during which the preferred securities were
held by such holder.

   Under certain circumstances, the debentures also may be redeemed for cash
and the proceeds of such redemption distributed to holders in redemption of
their preferred securities. Such a redemption would constitute a taxable
disposition of the redeemed preferred securities, and a holder would recognize
gain or loss as if it sold the redeemed preferred securities for cash. Please
read the "--Sale of Preferred Securities" section of this prospectus.

   If, however, the liquidation of the trust were to occur because of an event
which results in the trust being subject to federal income tax with respect to
income accrued or received on the debentures, the distribution of the
debentures to a holder of preferred securities would be a taxable event to the
trust and to each holder of preferred securities. In this case, each holder of
preferred securities would recognize gain or loss as if the holder had
exchanged its preferred securities for the debentures upon liquidation of the
trust.

Conversion of Preferred Securities into Common Stock

   Except to the extent attributable to accrued but unpaid interest on the
debentures, a holder of preferred securities generally will not recognize
income, gain or loss upon the conversion of preferred securities into Hanover
common stock. A holder will, however, recognize gain or loss upon the receipt
of cash in lieu of a fractional share of common stock equal to the amount of
cash so received less the holder's adjusted tax basis in the fractional share.
A holder's tax basis in the common stock received upon conversion generally
will be equal to the holder's adjusted tax basis in the preferred securities
delivered to the conversion agent for exchange, less the basis allocated to any
fractional share for which cash is received. A holder's holding period in the
common stock received upon conversion generally will include the holding period
of the preferred securities delivered to the conversion agent for exchange.

Adjustment of Conversion Price

   Treasury Regulations promulgated under Section 305 of the Code may treat
holders of preferred securities as having received a constructive distribution
from Hanover in certain events in which the conversion ratio of the debentures
into common stock is adjusted. Accordingly, under certain circumstances, a
reduction in the conversion price for the debentures may result in deemed
dividend income to holders of preferred securities to the extent of current and
accumulated earnings and profits of Hanover. In this case, holders of preferred
securities would be required to include their allocable share of such deemed
dividend income in gross income but would not receive any cash related thereto,
and holders would increase their tax basis in their preferred securities by the
amount includible in income. Holders are advised to consult their own tax
advisors as to the federal income tax consequences of adjustments in the
conversion ratio of the debentures.

Distributions on Common Stock

   The amount of any distribution on the common stock will be equal to the
amount of cash and the fair market value of any property distributed.
Generally, distributions will be treated as dividends, subject to tax as
ordinary income, to the extent of Hanover's current and accumulated earnings
and profits as determined for federal income tax purposes, then as a tax-free
return of capital to the extent of a holder's tax basis in the common stock and
thereafter as gain from the sale or exchange of the stock. In general, a
corporate recipient of a dividend distribution will qualify for a dividends
received deduction the amount of which varies, depending upon the level of the
holder's stock ownership, and which is subject to certain holding period,
taxable income and other limitations.

Sale of Common Stock

   Upon the sale or taxable exchange of common stock, a holder generally will
recognize gain or loss equal to the difference between the amount of cash and
the fair market value of any property received and such holder's adjusted tax
basis in the common stock. Any such gain or loss generally will be capital gain
or loss and will be long-term capital gain or loss if such holder's holding
period for the common stock exceeds one year. The determination of a holder's
basis and holding period in common stock received upon conversion of preferred
securities are discussed above under the "--Conversion of Preferred Securities
into Common Stock" section of this prospectus. A holder that purchases common
stock generally will have a basis in the common stock equal to the amount of
cash paid plus the fair market value of any property exchanged for the stock.

Information Reporting

   The trust will report the interest paid or accrued, including OID (if any),
during the year with respect to the debentures, and any gross proceeds received
by the trust from the retirement or redemption of the debentures, annually to
the holders of record of the preferred securities and to the IRS. The trust
currently intends to deliver such reports to holders of record not later than
January 31 following each calendar year. It is anticipated that persons who
hold preferred securities as nominees for beneficial owners will report the
required tax information to beneficial owners on Form 1099.

Backup Withholding

   Payments made on, and proceeds from the sale of, preferred securities, any
debentures distributed by the trust or any common stock received on conversion
may be subject to 31% backup withholding unless the holder complies with
certain identification requirements or otherwise qualifies for an exemption
from backup withholding. Backup withholding is not an additional tax. Any
withheld amounts generally will be refunded or credited against the holder's
federal income tax liability, provided the required information is timely filed
with the IRS.

Possible Tax Law Changes

   Holders of preferred securities should be aware that legislation has been
proposed by the Clinton Administration in the past that, if enacted, would have
denied an interest expense deduction to issuers of instruments such as the
preferred securities. While legislation of this kind is not currently pending,
it is possible that similar legislation ultimately could be enacted into law,
or that other developments may occur on or after the date of this prospectus
that would adversely affect the tax treatment of the preferred securities or
the trust. Changes of this kind could, among other things, result in the
redemption of the preferred securities for cash or the dissolution of the trust
and the distribution of the debentures to holders of the preferred securities.

                          CERTAIN ERISA CONSIDERATIONS

   Each fiduciary of a pension, profit-sharing or other employee benefit plan
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA") should consider the fiduciary standards of ERISA in the context of
the plan's particular circumstances before authorizing an investment in the
Preferred Securities. Accordingly, among other factors, the fiduciary should
consider whether the investment would satisfy the prudence and diversification
requirements of ERISA, whether the investment could result in an improper
delegation of fiduciary authority and whether the investment would be
consistent with the documents and instruments governing the plan.

   Section 406 of ERISA and Section 4975 of the Code prohibit plans, as well as
individual retirement accounts and Keogh plans subject to Section 4975 of the
Code, from engaging in certain transactions involving "plan assets" with
persons who are "parties in interest" under ERISA or "disqualified persons"
under the Code with respect to such plans. A violation of these "prohibited
transaction" rules may result in an excise tax or other liabilities under ERISA
and/or Section 4975 of the Code for such persons, unless exemptive relief is
available under an applicable statutory or administrative exemption. Employee
benefit plans that are governmental plans (as defined in Section 3(32) of
ERISA), certain church plans (as defined in Section 3(33) of ERISA) and foreign
plans (as described in Section 4(b)(4) of ERISA) are not subject to the
requirements of ERISA or Section 4975 of the Code.

   Under a regulation issued by the United States Department of Labor (the
"DOL"), the assets of the trust would be deemed to be "plan assets" of a plan
for purposes of ERISA and Section 4975 of the Code if "plan assets" of the plan
were used to acquire an equity interest in the trust and no exception were
applicable under the plan assets regulation. An "equity interest" is defined
under the plan assets regulation as any interest in an entity other than an
instrument that is treated as indebtedness under applicable local law and that
has no substantial equity features and specifically includes a beneficial
interest in a trust.

   Pursuant to an exception contained in the plan assets regulation, the assets
of the trust would not be deemed to be "plan assets" of investing plans if,
immediately after the most recent acquisition of any equity interest in the
trust, less than 25% of the value of each class of equity interests in the
trust were held by plans, other employee benefit plans not subject to ERISA or
Section 4975 of the Code (such as governmental, church and foreign plans), and
entities holding assets deemed to be "plan assets" of any plan. We cannot
assure you that the value of the preferred securities held by benefit plan
investors will be less than 25% of the total value of such preferred securities
at the completion of the initial offering or otherwise.

   Certain transactions involving the trust could be deemed to constitute
direct or indirect prohibited transactions under ERISA and Section 4975 of the
Code with respect to a plan if the preferred securities were acquired with
"plan assets" of such plan and assets of the trust were deemed to be "plan
assets" of plans investing in the trust. For example, if we are a party in
interest with respect to an investing plan (either directly or by reason of its
ownership of its subsidiaries), extensions of credit between the trust and us
(as represented by the debentures and the guarantee) would likely be prohibited
by Section 406(a)(1)(B) of ERISA and Section 4975(c)(1)(B) of the Code, unless
exemptive relief were available under an applicable administrative exemption
(see below). Because the assets of the trust may be considered "plan assets"
for ERISA purposes as a result of a plan's acquisition and holding of preferred
securities, a plan fiduciary should consider (a) whether powers which
potentially may be exercised by any person or entity with respect to the trust
or its assets would result in such person or entity being potentially deemed to
be a fiduciary and, therefore, a party in interest with respect to a plan
acquiring or holding preferred securities and (b) if so, whether such
acquisition and holding could result in a delegation of fiduciary authority
which is impermissible under the plan's governing instruments or any investment
management agreement with the plan. In making such determination, a plan
fiduciary should note that prior to a default, the trustees will have only
limited custodial and ministerial authority with respect to the assets of the
trust.

   The DOL has issued five prohibited transaction class exemptions that may
provide exemptive relief for direct or indirect prohibited transactions
resulting from the purchase or holding of the preferred securities,

                                       49
<PAGE>

assuming that assets of the trust were deemed to be "plan assets" of plans
investing in the trust (see above). Those class exemptions are PTCE 96-23 (for
certain transactions determined by in-house asset managers), PTCE 95-60 (for
certain transactions involving insurance company general accounts), PTCE 91-38
(for certain transactions involving bank collective investment funds), PTCE 90-
1 (for certain transactions involving insurance company separate accounts) and
PTCE 84-14 (for certain transactions determined by qualified professional asset
managers).
   Because the preferred securities may be deemed to be equity interests in the
trust for purposes of applying ERISA and Section 4975 of Code, the preferred
securities may not be purchased or held by any plan, any entity whose
underlying assets include "plan assets" by reason of any plan's investment in
an entity (a "plan asset entity") or any person investing "plan assets" of any
plan, unless the purchaser or holder is eligible for the exemptive relief
available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14. Any purchaser or
holder of the preferred securities or any interest therein will be deemed to
have represented by its purchase and holding that it either (a) is not a plan
or a plan asset entity and is not purchasing such securities on behalf of or
with "plan assets" of any plan or (b) is eligible for the exemptive relief
available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14. See "Transfer
Restrictions." Further, the fiduciaries of any plan or plan asset entity which
may purchase or hold preferred securities will be deemed as a result of such
acquisition or holding to have (a) directed the trust to invest in the
debentures, (b) authorized and directed any of the actions taken or which may
be taken with respect to the trust, the debentures and the preferred securities
by any of the trustees, the debenture trustee, the guarantee trustee, or us as
contemplated by the indenture, the debentures or the guarantee and (c) to have
appointed the trustees.

   Due to the complexity of these rules and the penalties that may be imposed
upon persons involved in non-exempt prohibited transactions, it is particularly
important that fiduciaries or other persons considering purchasing the
preferred securities on behalf of or with "plan assets" of any plan consult
with their counsel regarding the potential consequences if the assets of the
trust were deemed to be "plan assets" and the availability of exemptive relief
under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14.

                              REGISTRATION RIGHTS

   We and the trust entered into a registration agreement with the initial
purchasers of the preferred securities for the benefit of the holders of the
preferred securities wherein we and the trust agreed, at our sole expense, to

  . file as soon as practicable, but in no event more than 60 days after the
    original issuance of the preferred securities, a shelf registration
    covering resales of the preferred securities, the guarantee, the
    debentures and the related common stock issuable upon conversion of the
    preferred securities;

  . use our best efforts to cause the shelf registration statement to be
    declared effective under the Securities Act within 150 days after the
    original issuance of the preferred securities; and

  . use our best efforts to keep effective the shelf registration statement
    for two years or such other period as required under Rule 144(k) of the
    Securities Act or any successor rule thereto or, if earlier, such time as
    all of the applicable securities have been sold thereunder.

   We will provide to each holder for whom the shelf registration statement was
filed copies of the prospectus that is a part of the shelf registration
statement, notify each such holder when the shelf registration statement for
the securities has become effective and take certain other actions as are
required to permit unrestricted resales of the securities. A holder that sells
securities pursuant to the shelf registration statement will be required to be
named as a selling security holder in the related prospectus and to deliver a
prospectus to purchasers, will be subject to certain of the civil liability
provisions under the Securities Act in connection with such sales and will be
bound by the provisions of the registration agreement that are applicable to
such a holder (including certain indemnification rights and obligations).

   If (1) within 150 days of the original issuance of the preferred securities
the shelf registration statement has not been declared effective by the
Commission, or (2) if a shelf registration statement is declared effective by
the Commission and we or the trust fail to keep the shelf registration
statement continuously effective and usable (subject to some exceptions) for
the period required by the registration agreement, then additional interest,
referred to in this prospectus as special interest, will accrue on the
debentures, and corresponding special distributions will accrue on the
preferred securities and common securities, in each case from and including the
day following the registration default to but excluding the day on which the
registration default has been cured or has been deemed to have been cured.
Special interest and special distributions will be paid in cash quarterly in
arrears on each interest payment date commencing with the first interest
payment date following the applicable registration default and will accrue at a
rate so that the interest rate or distribution rate, as the case may, will be
increased 0.50% per annum of the principal amount or liquidation amount, as
applicable. Following the cure of a registration default, special interest and
special distributions will cease to accrue with respect to the applicable
registration default.

   Each security will contain a legend to the effect that the holder of the
security, by its acceptance of the security, will be deemed to have agreed to
be bound by the provisions of the registration agreement.

   The registration agreement is governed by, and construed in accordance with,
the laws of the State of New York. This summary of the registration agreement
is not complete and is subject to, and is qualified in its entirety by
reference to, all the provisions of the registration agreement. A form of the
registration agreement is available upon request.

                                SELLING HOLDERS

   The preferred securities were originally issued by the trust and sold by
Credit Suisse First Boston Corporation, Goldman Sachs & Co., Salomon Smith
Barney Inc. and Dain Rauscher Incorporated (the "initial purchasers") in a
transaction exempt from the registration requirements of the Securities Act, to
persons reasonably believed by such initial purchasers to be "qualified
institutional buyers" (as defined in Rule 144A under the Securities Act). The
holders named below and their transferees, pledgees, donees or successors
(collectively, the "Selling Holders") may from time to time offer and sell
pursuant to this prospectus any or all of the Preferred Securities, any
debentures and common stock issued upon conversion of the preferred securities.

   The following table sets forth information with respect to the Selling
Holders of the preferred securities and the respective number of preferred
securities beneficially owned by each Selling Holder that may be offered
pursuant to this prospectus.

(1) Comprises the shares of common stock into which the preferred securities
    held by such Selling Holder are convertible at the initial conversion
    price. The conversion price and the number of shares of common stock
    issuable upon conversion of the preferred securities are subject to
    adjustment under certain circumstances. Accordingly, the number of shares
    of common stock issuable upon conversion of the Preferred Securities may
    increase or decrease from time to time. Fractional shares will not be
    issued upon conversion of the preferred securities; rather, cash will be
    paid in lieu of fractional shares, if any.
(2) Assumes the offering of such shares by such Selling Holder pursuant to the
    registration statement of which this prospectus forms a part.
(3) No such holder may offer preferred securities or common stock pursuant to
    the registration statement of which this prospectus from a part until such
    holder is included as a Selling Holder in a supplement to this prospectus.
(4) Assumes that the unnamed holders of preferred securities or common stock or
    any future transferees, pledgees, donees or successors of or from any such
    named holder do not beneficially own any common stock other than the common
    stock issuable upon conversion of the preferred securities at the initial
    conversion price.

   None of the Selling Holders has, or within the past three years has had, any
position, office or other material relationship with the trust or Hanover
Compressor Company or any of their predecessors or affiliates.

   Because the Selling Holders may, pursuant to this prospectus, offer all or
some portion of the preferred securities or common stock they presently hold,
no estimate can be given as to the amount of the preferred securities or shares
of common stock that will be held by the Selling Holders upon termination of
any such sales. In addition, the Selling Holders identified above may have
sold, transferred or otherwise disposed of all or a portion of their preferred
securities or common stock since the date on which they provided the
information regarding their preferred securities or common stock, in
transaction exempt from the registration requirements of the Securities Act.

   Only Selling Holders identified above who beneficially own the preferred
securities or common stock set forth opposite each such Selling Holder's name
in the foregoing table on the effective date of the registration statement of
which this prospectus forms a part may sell such preferred securities or common
stock pursuant to the registration statement. We may from time to time include
additional Selling Holders in supplements to this prospectus.

   We will pay the expenses of registering the preferred securities and common
stock being sold hereunder.

                              PLAN OF DISTRIBUTION

   The securities offered hereby (the "offered securities") may be sold from
time to time to purchasers directly by the Selling Holders. Alternatively, the
Selling Holders may from time to time offer the offered securities to or
through underwriters, broker/dealers or agents, who may receive compensation in
the form of underwriting discounts, concessions or commissions from the Selling
Holders or the purchasers of such offered securities for whom they may act as
agents. The Selling Holders and any underwriters, broker/dealers or agents that
participate in the distribution of offered securities may be deemed to be
"underwriters" within the meaning of the Securities Act and any profit on the
sale of such securities by them and any underwriter, broker/dealer or agent may
be deemed to be underwriting discounts and commissions under the Securities
Act.

   The offered securities may be sold by the Selling Holders from time to time,
in one or more transactions at fixed prices, at prevailing market prices at the
time of sale, at varying prices determined at the time of sale or at negotiated
prices. Such prices will be determined by the Selling Holders. The sale of the
offered securities may be effected in transactions (which may involve crosses
or block transactions) (i) on any national securities exchange or quotation
service on which the offered securities may be listed or quoted at the time of
sale, (ii) in the over-the-counter market, (iii) otherwise than on such
exchanges or in the over-the-counter market or (iv) through the writing of
options. At the time a particular offering of the offered securities is made,
if required, a prospectus supplement will be distributed which will set forth
the names of the Selling Holders, the aggregate amount and type of offered
securities being offered, and, to the extent required, the terms of the
offering, including the name or names of any underwriters, broker/dealers or
agents, any discounts, commissions and other terms constituting compensation
from the Selling Holders and any discounts, commissions or concessions allowed
or reallowed or paid to broker/dealers.

   To comply with the securities laws of certain jurisdictions, if applicable,
the offered securities will be offered or sold in such jurisdictions only
through registered or licensed brokers or dealers. In addition, in certain
jurisdictions the offered securities may not be offered or sold unless they
have been registered or qualified for sale in such jurisdictions or any
exemption from registration or qualification is available and is complied with.

   Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the offered securities may be limited in its
ability to engage in market activities with respect to such securities. In
addition and without limiting the foregoing, each Selling Holder will be
subject to applicable provisions of the Exchange Act and the rules and
regulations thereunder, which provisions may limit the timing of purchases and
sales of any of the offered securities by the Selling Holders. All of the
foregoing may affect the marketability of the offered securities.

   Pursuant to the registration rights agreement, all expenses of the
registration of the offered securities will be paid by the Company, including,
without limitation, Commission filing fees and expenses of compliance with
state securities or "blue sky" laws. The Selling Holders will pay any
underwriting discounts and selling commissions. The Selling Holders will be
indemnified by us and the trust, jointly and severally, against certain civil
liabilities, including certain liabilities under the Securities Act, or will be
entitled to contribution in connection therewith. We and the trust will be
indemnified by the Selling Holders severally against certain civil liabilities,
including certain liabilities under the Securities Act, or will be entitled to
contribution in connection therewith.

   Pursuant to the registration rights agreement, we are required to use our
best efforts to keep the registration statement continuously effective for a
period of two years from its effective date or such shorter period that will
terminate upon the earlier of the date on which the offered securities shall
have been sold pursuant to the Registration Statement or the date on which the
offered Securities are permitted to be freely sold or distributed to the public
pursuant to any exemption from the registration requirements of the Securities
Act (including in reliance on Rule 144(k) but excluding in reliance on Rule
144A under the Securities Act). Notwithstanding these obligations, we may,
under certain circumstances, postpone or suspend the filing or the
effectiveness of the registration statement (or any amendments or supplements
thereto) or the sale of offered securities under the registration statement.

Item 15. Indemnification of Directors and Officers.

The Company

   The Company is empowered by Section 145 of the Delaware General Corporation
Law (the "DGCL"), subject to the procedures and limitations stated therein, to
indemnify any 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 by reason of
the fact that such person is or was a director, officer, employee or agent of
the company, or is or was serving at the request of the company as a director,
officer, employee or agent of another corporation or other enterprise, against
reasonable expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually incurred by him in connection with such action,
suit or proceeding, if such director, officer, employee or agent acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the company and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. The
Company is required by Section 145 to indemnify any person against reasonable
expenses (including attorneys' fees) actually incurred by him in connection
with an action, suit or proceeding in which he is a party because he is or was
a director, officer, employee or agent of the company or is or was serving at
the request of the company as a director, officer, employee or agent of another
corporation or other enterprise, if he has been successful, on the merits or
otherwise, in the defense of the action, suit or proceeding. Section 145 also
allows a corporation to purchase and maintain insurance or on behalf of any
such person against any liability asserted against him in any such capacity, or
arising out of his status as such, whether or not the corporation would have
the power to indemnify him against such liability under the provisions of
Section 145. In addition, Section 145 provides that indemnification pursuant to
its provisions is not exclusive of other rights of indemnification to which a
person may be entitled under any bylaw, agreement, vote of shareholders or
disinterested directors, or otherwise.

   Article Eighth of the Company's charter provides that the Company shall
indemnify and hold harmless all officers and directors of the Company, and
advance expenses reasonably incurred by such officers and directors in
defending any civil, criminal, administrative or investigative action, suit or
proceeding, in accordance with and to the fullest extent permitted by Section
145 of the DGCL.

The Trust

   The Declaration of Trust (the "Declaration") provides that no Trustee,
affiliate of any Trustee, or any officers, directors, shareholders, members,
partners, employees, representatives or agents of any Trustee, or any employee
or agent of the Trust or its affiliates (each an "Indemnified Person") shall be
liable, responsible or

Item 17. Undertakings

    (a) The registrants hereby undertake:

      (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;

       (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement; notwithstanding the foregoing, any
    increase or decrease in the volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement; and

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in the registration statement
    or any material change to such information in the registration
    statement;

  provided, however, that the undertakings set forth in clauses (i) and (ii)
  above do not apply if the information required to be included in a post-
  effective amendment by those clauses is contained in periodic reports filed
  with or furnished to the Securities and Exchange Commission by the Company
  pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
  1934 that are incorporated by reference in the registration statement.

     (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

                                      II-3
<PAGE>

     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

    (b) The registrant hereby undertakes that:

     (1) That for purposes of determining any liability under the Securities
  Act of 1933, the information omitted from the form of prospectus filed as
  part of a registration statement in reliance upon Rule 430A and contained
  in a form of prospectus filed by the registrants pursuant to Rule 424(b)(1)
  or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be
  part of this registration statement as of the time it was declared
  effective.

     (2) That, for purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

    (c) The registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Company's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange
Act of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the registration statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at hat time shall be deemed to be the
initial bona fide offering thereof.

   (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrants pursuant to the provisions set forth in Item 15, or otherwise,
the registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by a
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, subject to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

   (e) The registrant hereby undertakes to file an application for the purpose
of determining the eligibility of the trustee to act under subsection (a) of
Section 310 of the Trust Indenture Act ("Act") in accordance with the rules and
regulations prescribed by the Commission under Section 305(6)(2) of the Act.

such opinion will not be, deductible by the Sponsor in whole or in part for
United States Federal income tax purposes or (b) with respect to Debentures
which are no longer held by the Property Trustee, any portion of interest
payable by the Sponsor on the Debentures is not, or within 90 days of the date
of such opinion will not be, deductible by the Sponsor in whole or in part for
United States Federal income tax purposes.

     may, by vote, on behalf of the Holders of all of the Preferred Securities,
     waive any past Event of Default in respect of the Preferred Securities and
     its consequences, provided that, if the Event of Default:

        (i) is caused by a Debenture Event of Default that is not waivable under
            the Indenture, the Event of Default under the Declaration shall also
            not be waivable;

        (ii) is caused by a Debenture Event of Default that requires the consent
             or vote of greater than a majority in principal amount of the
             holders of the Debentures (a "Super Majority") to be waived under
             the Indenture, the Event of Default under the Declaration may only
             be waived by the vote of the Holders of at least the proportion in
             liquidation amount of the Preferred Securities that the relevant
             Super Majority represents of the aggregate principal amount of the
             Debentures outstanding;

        (iii) is the result of a default by the Trust in the payment of any
              Distribution when it becomes due and payable, which default has
              continued for 30 days (subject to the deferral of any due date in
              the case of a Default Period), the Event of Default shall not be
              waivable; or

        (iv) is the result of a default by the Trust in the payment of any
             Redemption Price of any Preferred Security when it becomes due and
             payable, the Event of Default shall not be waivable.

     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 Declaration and
the Securities, as permitted by the Trust Indenture Act.

                                       10
<PAGE>

     Upon such waiver, any such default shall cease to exist, and any Event of
Default with respect to the Preferred Securities arising therefrom shall be
deemed to have been cured for every purpose of this Declaration, but no such
waiver shall extend to any subsequent or other default or an Event of Default
with respect to the Preferred Securities or impair any right consequent thereon.
Any waiver by the Holders of the Preferred Securities of an Event of Default
with respect to the Preferred Securities shall also be deemed to constitute a
waiver by the Holders of the Common Securities of any such Event of Default with
respect to the Common Securities for all purposes of this Declaration without
any further act, vote, or consent of the Holders of the Common Securities.

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

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

        (ii) requires the consent or vote of a Super Majority to be waived,
             except where the Holders of the Common Securities are deemed to
             have waived such Event of Default under the Declaration as provided
             below in this Section 2.06(b), the Event of Default under the
             Declaration may only be waived by the vote of the Holders of at
             least the proportion in liquidation amount of the Common Securities
             that the relevant Super Majority represents of the aggregate
             principal amount of the Debentures outstanding;

provided further, 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 the effects of all Events of Default with
respect to the Preferred Securities have been cured, waived or otherwise
eliminated, and until such Events of Default have been so cured, waived or
otherwise eliminated, the 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 Section 316(a)(1)(A) and 316(a)(1)(B) of the
Trust Indenture Act are hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act. Subject to the foregoing
provisions of this Section 2.06(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
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default with respect to the Common Securities or impair any right
consequent thereon.

(c)  A waiver of an Event of Default under the Indenture by the Property Trustee
     at the direction of the Holders of the Preferred Securities, constitutes a
     waiver of the corresponding Event of Default under this Declaration. The
     foregoing provisions of this Section 2.06(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

                                       11

     of an Event of Default actually known to the Property Trustee, (i) transmit
     by mail, first-class postage prepaid, to the Holders of the Securities, and
     (ii) transmit by any means provided for in this Declaration to the
     Administrative Trustees and the Sponsor, notices of all defaults actually
     known to 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 an Event of Default, not
     including any periods of grace and irrespective of the giving of any
     notice); provided that, except for a default in the payment of principal of
     (or premium, if any) or interest on any of the Debentures or in the payment
     of any sinking fund installment established for the Debentures, the
     Property Trustee shall be protected in withholding such notice if and so
     long as the board of directors, the executive committee, or a trust
     committee of directors and/or Responsible Officers of the 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 knowledge of any default
     except:

        (i)  a default under Sections 5.01(1) and 5.01(2) of the Indenture; or

        (ii) any default as to which the Property Trustee shall have received
             written notice.

              conferred upon the Debenture Trustee with respect to the
              Debentures, (B) waive any past default that is waivable under
              Section 5.13 of the Indenture, (C) exercise any right to rescind
              or annul any declaration that the principal of all the Debentures
              shall be due and payable, or (D) consent to any amendment,
              modification or termination of the Indenture or the Debentures
              where such consent shall be required unless, in the case of each
              action described in clause (A), (B), (C) or (D), the Trust shall
              have received an opinion of counsel to the effect that such
              modification will not cause more than an insubstantial risk that
              for United States federal income tax purposes the Trust will not
              be classified as a grantor trust.

Section 3.08   Powers and Duties of the Property Trustee.

(a)  The legal title to the Debentures shall be owned by and held of record in
     the name of the Property Trustee in trust for the benefit of the Holders of
     the Securities. The right, title and interest of the Property Trustee to
     the Debentures shall vest automatically in each Person who may hereafter be
     appointed as Property Trustee in accordance with Section 5.06. Such vesting
     and cessation of title shall be effective whether or not conveyancing
     documents with regard to the Debentures have been executed and delivered.

(b)  The Property Trustee shall not transfer its right, title and interest in
     the Debentures 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 Debentures held by the Property Trustee,
            deposit such funds into the Property Trustee Account and 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
            Declaration;

                                       17
<PAGE>

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

        (iii) upon written notice of distribution issued by the Administrative
              Trustees in accordance with the terms of the Securities, engage in
              such ministerial activities as so directed as shall be necessary
              or appropriate to effect the distribution of the Debentures to
              Holders of Securities upon the occurrence of certain special
              events (as may be defined in the terms of the Securities) arising
              from a change in law or a change in legal interpretation or other
              specified circumstances pursuant to the terms of the Securities.

(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
     the Securities.

(e)  The Property Trustee shall take any Legal Action which arises out of or in
     connection with an Event of Default or the Property Trustee's duties and
     obligations under this Declaration or the Trust Indenture Act; provided,
     however, that if a Debenture Event of Default has occurred and is
     continuing and such event is attributable to the failure of the Sponsor to
     pay interest or principal on the Debentures on the date such interest or
     principal is otherwise payable (or in the case of redemption, on the
     redemption date), then a holder of Preferred Securities may institute a
     legal proceeding directly for enforcement of payment to such Holder of the
     principal of or interest on the Debentures having a principal amount equal
     to the aggregate liquidation amount of the Preferred Securities of such
     Holder (a "Direct Action") on or after the respective due date specified in
     the Securities. In connection with such Direct Action, the Debenture Issuer
     shall be subrogated to the rights of such Holder of Preferred Securities
     with respect to payments on the Preferred Securities to the extent of any
     payment made by the Sponsor to such Holder of Preferred Securities in such
     Direct Action. In addition, if the Property Trustee fails to enforce its
     rights under the Debentures (other than rights arising from an Event of
     Default described in the immediately preceding sentence) after any Holder
     of Preferred Securities shall have made a written request to the Property
     Trustee to enforce such rights, such Holder of Preferred Securities may, to
     the fullest extent permitted by law, institute a Direct Action to enforce
     such rights. 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 Debentures.

(f)  The Property Trustee shall not resign as a Trustee unless 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; or

        (ii) a Successor Property Trustee has been appointed and has accepted
             that appointment in accordance with Section 5.06.

(g)  The Property Trustee shall have the legal power to exercise all of the
     rights, powers and privileges of a holder of Debentures under the Indenture
     and, if an Event of Default occurs and is continuing, the Property Trustee
     shall, for the benefit of Holders of the Securities,

                                       18
<PAGE>

     enforce its rights as holder of the Debentures subject to the rights of the
     Holders pursuant to the terms of such Securities.

(h)  The Property Trustee will act as Paying Agent and Registrar in Wilmington,
     Delaware 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
     Paying Agent may be removed by the Property Trustee at any time and a
     successor Paying Agent or additional Paying Agents may be appointed at any
     time by the Property Trustee.

(i)  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.

(j)  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, and the Property Trustee shall not take any
     action that is inconsistent 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 of all Events of Default that may have occurred, shall
     undertake to perform only such duties as are specifically set forth in this
     Declaration and no implied covenants shall be read into this Declaration
     against the Property Trustee. In case an Event of Default has occurred
     (that has not been cured or waived pursuant to Section 2.06), the Property
     Trustee shall exercise such of the rights and powers vested in it by this
     Declaration, 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)  No provision of this Declaration shall be construed to relieve the Property
     Trustee from liability for its own negligent action, its own negligent
     failure to act, 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:

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

                                       19
<PAGE>

                    Declaration; but 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 Declaration;

        (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 not less than a
              Majority in liquidation amount of the Securities relating to the
              time, method and place of conducting any proceeding for any remedy
              available to the Property Trustee, or exercising any trust or
              power conferred upon the Property Trustee under this Declaration;

        (iv) no provision of this Declaration 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;

        (v)  the Property Trustee's sole duty with respect to the custody, safe
             keeping and physical preservation of the Debentures 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 Declaration
             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
             Debentures 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 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 Declaration, nor shall the
               Property Trustee be liable for the default or misconduct of the
               Administrative Trustees or the Sponsor.

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

             provided to the Property Trustee security satisfactory to the
             Property Trustee, against the costs, expenses (including its
             attorneys' fees and expenses) and liabilities that might be

<PAGE>

               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;

        (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 Declaration, 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 Declaration the Property
             Trustee shall deem it desirable to receive instructions with
             respect to enforcing any remedy or right or taking any other action

             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 acting in accordance with such
             instructions;

              discretion or rights or powers conferred upon it by this
              Declaration.

(b)  No provision of this Declaration shall be deemed to impose any duty or
     obligation on the 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.

Section 3.11   Delaware Trustee.

     Notwithstanding any other provision of this Declaration 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 duties and responsibilities of the
Administrative Trustees or the Property Trustee described in this Declaration.
Except as set forth in Section 5.02, the Delaware Trustee shall be a Trustee for
the sole and limited purpose of fulfilling the requirements of Section 3807 of
the Business Trust Act.

     Delaware Trustee or the Property Trustee, consolidate, amalgamate, merge
     with or into, or be replaced by a trust organized as such under the laws of
     any State or the District of Columbia; provided that:

        (i) if the Trust is not the surviving entity, the 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 Preferred Securities (the
                "Successor Securities") as long as the Successor Securities
                rank, with respect to participation in the profits and
                distributions and payments upon liquidation, redemption and
                otherwise at least as high as the Preferred Securities rank with
                respect to participation in the profits and dividends and

                                       23
<PAGE>

        (ii) the Debenture Issuer appoints a Trustee of such Successor Entity
             possessing the same powers and duties of the Property Trustee as
             the Holder of the Debentures;

        (iii) the Preferred Securities or any Successor Securities are listed,
              or any Successor Securities will be listed upon notification of
              issuance, on any national securities exchange or with any other
              organization on which the Preferred Securities are then listed or
              quoted;

        (iv) such merger, consolidation, amalgamation, or replacement does not
             cause the Preferred Securities (including any Successor Securities)
             to be downgraded by any nationally recognized statistical rating
             organization;

        (v)  such merger, consolidation, amalgamation, replacement or does not
             adversely affect the powers, preferences and other special rights

             Securities) in any material respect;

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

        (vii) prior to such merger, consolidation, amalgamation, or replacement
              , the Sponsor has received an opinion of a nationally recognized
              independent counsel (reasonably acceptable to the Property
              Trustee) to the Trust experienced in such matters to the effect
              that:

              (A) the Successor Entity will be treated as a grantor trust for
                  United States federal income tax purposes;

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

              (C) such merger, consolidation, amalgamation or replacement will
                  not adversely affect the limited liability of the Holders of
                  the Securities (including any Successor Securities); and

        (viii) the Sponsor provides a guarantee to the Holders of the Successor
               Securities with respect to the Successor Entity having
               substantially the same terms as the Preferred Securities
               Guarantee; and

        (ix) such merger, consolidation, amalgamation, replacement or lease is
             not a taxable event for holders of the Preferred Securities.

(c)  Notwithstanding Section 3.15(b), the Trust shall not, except with the
     consent of Holders of 100% in liquidation amount of the Securities,
     consolidate, amalgamate, merge with or into, or be replaced by any other
     entity or permit any other entity to consolidate, amalgamate,

                                       24
<PAGE>

     merge with or into, or replace it if such consolidation, amalgamation,
     merger or replacement would cause the Trust or Successor Entity to be
     classified as other than a grantor trust for United States federal income
     tax purposes.

        (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 Sponsor and the resigning Delaware Trustee; and

        (iii) no such resignation of a Special Trustee shall be effective until
              the 60th day following delivery of the instrument of resignation
              of the Special Trustee to the Sponsor and the Trust or such later
              date specified in such instrument during which period the Holders
              of the Preferred Securities shall have the right to appoint a
              successor Special Trustee as provided in this Section 5.06.

(f)  The Holders of the Common Securities shall use their best efforts to
     promptly appoint a Successor Property Trustee or Successor Delaware
     Trustee, as the case may be, if the Property Trustee or the Delaware
     Trustee delivers an instrument of resignation in accordance with this
     Section 5.06.

(g)  If no Successor Property Trustee or Successor Delaware Trustee shall have
     been appointed and accepted appointment as provided in this Section 5.06
     within 60 days after delivery to the Sponsor and the Trust of an instrument
     of resignation or removal, at the cost of the Sponsor the resigning
     Property Trustee or Delaware Trustee, resigning or being removed as

                                       30
<PAGE>

     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.

(h)  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 5.07   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 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
5.06.

Section 5.08   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 annul, dissolve or terminate the Trust.

     Whenever a vacancy in the number of Administrative Trustees shall occur,
until such vacancy is filled by the appointment of a Administrative Trustee in
accordance with Section 5.06, 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 Declaration.

Section 5.09   Meetings.

     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 meetings of the Administrative
Trustees shall be hand delivered or otherwise delivered in writing (including by
facsimile or overnight courier) not less than 24 hours before such 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 a
Administrative Trustee at a meeting shall constitute a waiver of notice of such
meeting except where a 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 Declaration, 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 and without prior notice
by the unanimous written consent of the Administrative Trustees.

<PAGE>

     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. In the event a Special Trustee is holding office
pursuant to Section 5.06, such Special Trustee shall have the same rights as an
Administrative Trustee with respect to participation in a meeting of the
Administrative Trustees.

Section 5.10   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

     Section 3.06, including any registration statement or amendment thereto
     filed with the Commission, or making any other governmental filing; 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 the
     Trust, as set forth herein.

Section 5.11   Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Property Trustee or the Delaware Trustee, as the
case may be, may be merged or converted or with which either 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.

     Trust shall have no securities or other interests in the assets of the
     Trust other than the Preferred Securities and the Common Securities. The
     Trust shall issue no Securities in bearer form.

(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 Declaration, the
     Securities so issued shall be deemed to be validly issued, fully paid and
     non-assessable, subject to Section 10.01 with respect to the Common
     Securities.

(d)  Every Person, by virtue of having become a Holder or a Preferred Security
     Beneficial Owner in accordance with the terms of this Declaration, shall be
     deemed to have expressly assented and agreed to the terms of, and shall be
     bound by, this Declaration.

(e)  Every Person, by virtue of having become a Holder or a Preferred Securities
     Beneficial Owner in accordance with the terms of this Declaration, shall be
     deemed to have covenanted to treat the Debentures as indebtedness and the
     Securities as evidence of an indirect beneficial ownership interest in the
     Debentures.

Section 7.02  Execution and Authentication.

(a)  The Securities shall be signed on behalf of the Trust by one 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 delivery of the Declaration
     any such person was not such a Administrative Trustee.

(b)  One Administrative Trustee shall sign the Preferred Securities and the
     Common Securities for the Trust by manual or facsimile signature.

                                       33
<PAGE>

     A Preferred Security shall not be valid until authenticated by the manual
or facsimile signature of an authorized signatory of the Property Trustee. The
signature shall be conclusive evidence that the Preferred Security has been
authenticated under this Declaration.

     Upon a written order of the Trust signed by one Administrative Trustee, the
Property Trustee shall authenticate the Preferred Securities for original issue
by executing the Property Trustee's certificate of authentication contained in
the form of Preferred Securities attached hereto as Exhibit A-1. 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.

     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 Declaration to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee to deal with the Company 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 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 Declaration.
Certificates may be printed, lithographed or engraved or may be produced in any
other manner as is reasonably acceptable to the Administrative Trustees, as
evidenced by their execution thereof. The Securities may have letters, numbers,
notations or other marks of identification or designation and such legends or
endorsements required by law, stock exchange 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). The Trust at the direction of
the Sponsor shall furnish any such legend not contained in Exhibit A-1 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 and A-2 are part
of the terms of this Declaration and to the extent applicable, the Property
Trustee and the Sponsor, by their execution and delivery of this Declaration,
expressly agree to such terms and provisions and to be bound thereby.

     The Preferred Securities are being offered and sold by the Trust pursuant
to a Purchase Agreement relating to the Preferred Securities, dated December 9,
1999, among the Trust, the Sponsor and the Purchasers named therein (the
"Purchase Agreement").

(a)  Global Securities. Preferred Securities offered and sold to Qualified
     Institutional Buyers ("QIBs") in reliance on Rule 144A under the Securities
     Act ("Rule 144A") as provided in the Purchase Agreement, shall be issued in
     the form of one or more permanent global Securities in definitive, fully
     registered form without distribution coupons with the appropriate global
     legends, ERISA legend and Restricted Securities Legend set forth in Exhibit
     A-1 hereto (each, a "Rule 144A Global Preferred Security"), which shall be
     deposited on behalf of the purchasers of the Preferred Securities
     represented thereby with the Property Trustee, at its Wilmington, Delaware
     office, as custodian for the Depositary, and registered in the name of the
     Depositary or a nominee

                                       34
<PAGE>

     of the Depositary, duly executed by an Administrative Trustee on behalf of
     the Trust and authenticated by the Property Trustee as provided herein. The
     number of Preferred Securities represented by the Rule 144A Global
     Preferred Security may from time to time be increased or decreased by
     adjustments made on the records of the Property Trustee and the Depositary
     or its nominee as hereinafter provided.

(b)  Book-Entry Provisions. This Section 7.03(b) shall apply only to the Rule
     144A Global Preferred Securities and such other Preferred Securities in
     global form as may be authorized by the Trust to be deposited with or on
     behalf of the Depositary.

     An Administrative Trustee on behalf of the Trust shall execute and the
Property Trustee shall, in accordance with this Section 7.03, authenticate and
deliver initially one or more Rule 144A Global Preferred Securities that (a)
shall be registered in the name of Cede & Co. or other nominee of such
Depositary and (b) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's written instructions or held by the Trustee as
custodian for the Depositary.

     Members of, or participants in, the Depositary ("Participants") shall have
no rights under this Declaration with respect to any Rule 144A Global Preferred
Security held on their behalf by the Depositary or by the Property Trustee as
the custodian of the Depositary or under such Rule 144A Global Preferred
Security, and the Depositary 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
Rule 144A 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 Depositary or
impair, as between the Depositary and its Participants, the operation of
customary practices of such Depositary governing the exercise of the rights of a
holder of a beneficial interest in any Rule 144A Global Preferred Security.

(c)  Certificated Securities. Except as provided in Section 7.03(d), owners of
     beneficial interests in the Rule 144A Global Preferred Security will not be
     entitled to receive physical delivery of certificated Preferred Securities.

(d)  A Global Preferred Security deposited with the Depositary or with the
     Property Trustee as custodian for the Depositary pursuant to this Section
     7.03 shall be transferred to the beneficial owners thereof in the form of
     certificated Preferred Securities only if such transfer complies with
     Section 9.02 and (i) the Depositary notifies the Company that it is
     unwilling or unable to continue as Depositary for such Global Preferred
     Security or if at any time such Depositary ceases to be a "clearing agency"
     registered under the Exchange Act, at a time when the Depositary is
     required to be so registered to act as such depositary, (ii) the Sponsor on
     behalf of the Trust in its sole discretion determines that such Global
     Preferred Security shall be so exchangeable, or (iii) an Event of Default
     has occurred and is continuing.

(e)  Any Global Preferred Security that is transferable to the beneficial owners
     thereof in the form of certificated Preferred Securities pursuant to this
     Section 7.03 shall be surrendered by the Depositary to the Property Trustee
     located in Wilmington, Delaware, to be so transferred, in whole or from
     time to time in part, without charge, and the Property Trustee shall

                                       35
<PAGE>

     authenticate and deliver, upon such transfer of each portion of such Global
     Preferred Security, an equal aggregate liquidation amount of Preferred
     Securities of authorized denominations in the form of certificated
     Preferred Securities. Any portion of a Global Preferred Security
     transferred pursuant to this Section shall be registered in such names as
     the Depositary shall direct. Any Preferred Security in the form of
     certificated Preferred Securities delivered in exchange for an interest in
     the Rule 144A Global Preferred Security shall, except as otherwise provided
     by Section 9.01, bear the Restricted Securities Legend set forth in Exhibit
     A hereto.

(f)  Subject to the provisions of Section 7.03(e), the registered 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 a holder is entitled to take under
     this Declaration or the Securities.

(g)  In the event of the occurrence of any of the events specified in Section
     7.03(d), the Trust will promptly make available to the Property Trustee a
     reasonable supply of certificated Securities in definitive, fully
     registered form without distribution coupons.

Section 7.04  Registrar, Paying Agent and Conversion Agent.

     The Trust shall maintain in Wilmington, Delaware (i) an office or agency
where Preferred Securities may be presented for registration of transfer or for
exchange ("Registrar"), (ii) an office or agency where Preferred Securities may
be presented for payment ("Paying Agent") and (iii) an office or agency where
Securities may be presented for conversion ("Conversion Agent"). The Registrar
shall keep a register of the Preferred Securities and of their transfer and
exchange. The Trust may appoint the Registrar, the Paying Agent and the
Conversion Agent and may appoint one or more co-registrars, one or more
additional paying agents and one or more additional conversion agents in such
other locations as it shall determine. The term "Paying Agent" includes any
additional paying agent and the term "Conversion Agent" includes any additional
conversion agent. The Trust may change any Paying Agent, Registrar, co-registrar
or Conversion Agent without prior notice to any Holder. The Trust shall notify
the Property Trustee of the name and address of any Agent not a party to this
Declaration. If the Trust fails to appoint or maintain another entity as
Registrar, Paying Agent or Conversion Agent, the Property Trustee shall act as
such. The Trust or any of its Affiliates may act as Paying Agent, Registrar, or
Conversion Agent. The Trust shall act as Paying Agent, Registrar, co-registrar,
and Conversion Agent for the Common Securities.

     The Trust initially appoints the Property Trustee as Registrar, Paying
Agent, and Conversion 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 principal or distribution on the Securities, and will notify the
Property Trustee if there are insufficient funds. 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

                                       36
<PAGE>

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 Securities.

     If the Holder of a Security claims that the Security 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 on behalf of the Trust shall issue
and, with respect to the Preferred Securities, the Property Trustee shall
authenticate a replacement Security if the Property Trustee's and the Trust's
requirements, as the case may be, are met. If required by the Property Trustee
or the Trust, an indemnity bond must be sufficient in the judgment of both 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 Sponsor may charge
for its expenses in replacing a Security.

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

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 protected purchaser.

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

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

Section 7.08  Preferred Securities in Treasury.

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

                                       37
<PAGE>

on any such direction, waiver or consent, only Securities which the Property
Trustee actually knows are so owned shall be so disregarded.

Section 7.09  Temporary Securities.

     Until definitive Securities are ready for delivery, an Administrative
Trustee 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
an Administrative Trustee considers appropriate for temporary Securities.
Without unreasonable delay, an Administrative Trustee shall prepare and deliver
to the Property Trustee Preferred Securities in certificated form (other than in
the case of Preferred Securities in global form) and thereupon any or all
temporary Preferred Securities (other than any such Preferred Securities in
global form) may be surrendered in exchange therefor, at the office of the
Registrar, and the Property Trustee shall authenticate and deliver an equal
aggregate liquidation amount of definitive Preferred Securities in certificated
form in exchange for temporary Preferred Securities (other than any such
Preferred Securities in global form).

Section 7.10  Cancellation.

     The Trust at any time may deliver Preferred Securities to the Property
Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall
forward to the Property Trustee any Preferred Securities surrendered to them for
registration of transfer, redemption, conversion, exchange or payment. The
Property Trustee shall promptly cancel all Preferred Securities, surrendered for
registration of transfer, redemption, conversion, exchange, payment, replacement
or cancellation and shall return such canceled Preferred Securities to the
Administrative Trustees. The Trust may not issue new Preferred Securities to
replace Preferred Securities that it has paid or that have been delivered to the
Property Trustee for cancellation or that any holder has converted.

        (v)  the entry of a decree of judicial dissolution of the Holder of the

     is hereby authorized to take such action) shall file a certificate of
     cancellation with the Secretary of State of the State of Delaware
     terminating the Trust and, upon such filing, the respective obligations and
     responsibilities of the Trustees and the Trust created and continued
     hereby, shall terminate.

(c)  The provisions of Sections 3.09, 4.03, 10.01(b), 10.04, the last sentence
     of Section 3.06 and Article X shall survive the termination of the Trust.

                                    ARTICLE IX

                             Transfer and Exchange

Section 9.01  General.

(a)  Where Preferred Securities are presented to the Registrar or a co-registrar
     with a request to register a transfer or to exchange them for an equal
     number of Preferred Securities represented by different certificates, the
     Registrar shall register the transfer or make the exchange if its
     requirements for such transactions are met. To permit registrations of
     transfers and exchanges, the Administrative Trustee in accordance with this
     Declaration shall execute and deliver and the Property Trustee shall
     authenticate Preferred Securities at the Registrar's request.

                                       39
<PAGE>

(b)  Securities may only be transferred, in whole or in part, in accordance with
     the terms and conditions set forth in this Declaration and in the terms of
     the Securities. To the fullest extent permitted by law, any transfer or
     purported transfer of any Security not made in accordance with this
     Declaration shall be null and void.

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

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

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

(c)  The Administrative Trustees shall provide for the registration of
     Securities and of transfers of Securities, which will be effected without
     charge but only upon payment (with such indemnity as the Administrative
     Trustees or Property Trustee 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 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 in
     accordance with Section 7.10. 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 Declaration.

(d)  The Trust shall not be required (i) to issue, register the transfer of, or
     exchange, Preferred Securities during a period beginning at the opening of
     business 15 days before the day of any selection of Preferred Securities
     for redemption set forth in the terms of the Securities as set forth in
     Annex I hereto and ending at the close of business on the day of selection,
     or (ii) to register the transfer or exchange of any Preferred Security so
     selected for redemption in whole or in part, except the unredeemed portion
     of any Preferred Security being redeemed in part.

(e)  All Preferred Securities issued upon any transfer or exchange pursuant to
     the terms of this Declaration shall evidence the same security and shall be
     entitled to the same benefits under this Declaration as the Preferred
     Securities surrendered upon such transfer or exchange.

Section 9.02  Transfer Procedures and Restrictions.

(a)  General. Subject to Sections 9.02(b) and 9.02(j)(ii), if Preferred
     Securities are issued upon the transfer, exchange or replacement of
     Preferred Securities bearing the Restricted Securities Legend set forth in
     Exhibit A-1 hereto, or if a request is made to remove such Restricted

                                       40
<PAGE>

     Securities Legend on Preferred Securities, the Preferred Securities so
     issued shall bear the Restricted Securities Legend, or the Restricted
     Securities Legend shall not be removed, as the case may be, unless there is
     delivered to the Trust and the Property Trustee such satisfactory evidence,
     which may include an opinion of counsel, as may be reasonably required by
     the Company, that (i) neither the legend nor the restrictions on transfer
     set forth therein are required to ensure that transfers thereof comply with
     the provisions of Rule 144A or Rule 144 under the Securities Act or (ii)
     that such Securities are not "restricted" within the meaning of Rule 144
     under the Securities Act. Upon provision of such satisfactory evidence, the
     Property Trustee, at the written direction of an Administrative Trustee on
     behalf of the Trust, shall authenticate and deliver Preferred Securities
     that do not bear the Restricted Securities Legend.

(b)  Transfers After Effectiveness of Shelf Registration Statement. After the
     effectiveness of a Shelf Registration Statement for any Preferred
     Securities, all requirements pertaining to Restricted Securities Legends on
     any Preferred Security included within such Shelf Registration Statement
     will cease to apply, and beneficial interests in a Preferred Security in
     global form without Restricted Securities Legends will be available to
     transferees of such Preferred Securities, upon directions to transfer such
     Holder's beneficial interest in the Rule 144A Global Preferred Security.
     After the effectiveness of the Shelf Registration Statement, the
     Administrative Trustees shall execute and deliver and the Property Trustee
     shall authenticate a Preferred Security in global form without the
     Restricted Securities Legend (the "Unrestricted Global Preferred Security")
     to deposit with the Depositary to evidence transfers of beneficial
     interests from the Rule 144A Global Preferred Security.

(c)  [Reserved]

(d)  Transfer and Exchange of Definitive Preferred Securities.  When Definitive
     Preferred Securities are presented to the Registrar or co-Registrar

        (x) to register the transfer of such Definitive Preferred Securities; or

        (y) to exchange such Definitive Preferred Securities for an equal number
            of Definitive Preferred Securities of another denomination.

the Registrar or co-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:

        (i)  shall be duly endorsed or accompanied by a written instrument of
             transfer in form reasonably satisfactory to an Administrative
             Trustee on behalf of the Trust and the Registrar or co-registrar,
             duly executed by the Holder thereof or his attorney duly authorized
             in writing; and

        (ii)  in the case of Definitive Preferred Securities that are Restricted
              Preferred Securities, and are being transferred or exchanged (x)
              pursuant to an effective registration statement under the
              Securities Act or (y) pursuant to, and in compliance with, clause
              (A) or (B) below:

                                       41
<PAGE>

               (A)  if such Restricted Preferred Securities are being delivered
                    to the Registrar by a Holder for registration in the name of
                    such Holder, without transfer, such Holder shall deliver a
                    certification to that effect (in the form set forth on the
                    reverse of the Preferred Security); or

                (B) if such Restricted Preferred Securities are being
                    transferred pursuant to an exemption from registration in
                    accordance with Rule 144A or Rule 144 under the Securities
                    Act such Holder shall deliver: (i) a certification to that
                    effect (in the form set forth on the reverse of the
                    Preferred Security) and (ii) if the Trust or Registrar so
                    requests, evidence reasonably satisfactory to them as to the
                    compliance with the restrictions set forth in the Restricted
                    Securities Legend.

     Definitive Preferred Securities that are transferred to QIBs in accordance
with Rule 144A under the Securities Act must take delivery of their interests in
the Preferred Securities in the form of a beneficial interest in the Rule 144A
Global Preferred Security in accordance with Section 9.02(e).

(e)  Restrictions on Transfer of a Definitive Preferred Security for a
     Beneficial Interest in a Global Preferred Security. A Definitive Preferred
     Security may not be exchanged for a beneficial interest in a Global
     Preferred Security except upon satisfaction of the requirements set forth
     below. 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, together with
     written instructions directing the Property Trustee to make, or to direct
     the Depositary to make, an adjustment on its books and records with respect
     to such Global Preferred Security to reflect an increase in the number of
     the Preferred Securities represented by the Global Preferred Security, then
     the Property Trustee shall cancel such Definitive Preferred Security and
     cause, or direct the Depositary to cause, the aggregate number of Preferred
     Securities represented by the Global Preferred Security to be increased
     accordingly. If no Global Preferred Securities are then outstanding, the
     Administrative Trustee shall execute and deliver and the Property Trustee
     shall authenticate, upon written order of any Administrative Trustee, an
     appropriate number of Preferred Securities in global form.

(f)  Transfer and Exchange of Global Preferred Securities. The transfer and
     exchange of Global Preferred Securities or beneficial interests therein
     shall be effected through the Depositary, in accordance with this
     Declaration (including applicable restrictions on transfer set forth
     herein, if any) and the procedures of the Depositary therefor.

(g)  Transfer of a Beneficial Interest in a Global Preferred Security for a
     Definitive Preferred Security.

        (i)  The transfer of a beneficial interest in a Rule 144A Global
             Preferred Security in exchange for a Definitive Preferred Security
             will require the delivery by the transferee of a transfer
             certificate in the form set forth in Exhibit A-1.

        (ii) Definitive Preferred Securities issued in exchange for a beneficial
             interest in a Global Preferred Security pursuant to this Section
             9.02(g) shall be registered in

                                       42

             pursuant to instructions from its Participants or indirect
             participants or otherwise, shall instruct the Property Trustee. The
             Property Trustee shall deliver such Preferred Securities to the
             Persons in whose names such Preferred Securities are so registered
             in accordance with the instructions of the Depositary.

(h)  Restrictions on Transfer and Exchange of Global Preferred Securities.
     Notwithstanding any other provisions of this Declaration (other than the
     provisions set forth in Section 7.03), a Global Preferred Security may not
     be transferred as a whole except by the Depositary to a nominee of the
     Depositary or another nominee of the Depositary or by the Depositary or any
     such nominee to a successor Depositary or a nominee of such successor
     Depositary.

               following form, unless otherwise determined by the Sponsor in
               accordance with applicable law.

(k)  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
     the Declaration or redeemed, repurchased or cancelled in accordance with
     the terms of this Declaration, such Global Preferred Security shall be
     returned to the Depositary for cancellation or retained and cancelled by
     the Property Trustee. At any time prior to such cancellation, if any
     beneficial interest in a Global Preferred Security is exchanged for

                                       44

     Securities 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.

(l)  [Reserved]

(m)  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 Depositary or other Person with respect to the accuracy of
             the records of the Depositary 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 Depositary) 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 registered
             Holders (which shall be the Depositary 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
             Depositary subject to the applicable rules and procedures of the
             Depositary. The Property Trustee may conclusively rely and shall be
             fully protected in relying upon information furnished by the
             Depositary or 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 Declaration or under
              applicable law with respect to any transfer of any interest in any
              Preferred Security (including any transfers between or among
              Depositary 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 Declaration, and to examine the same to determine
              substantial compliance as to form with the express requirements
              hereof.

Section 9.03  Deemed Security Holders.

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

shall have no notice obligations to the Preferred Security Beneficial Owners.

depositary with respect to the Preferred Securities, the Administrative Trustees

     Limitation of Liability of Holders of Securities, Trustees or Others

Section 10.01  Liability.

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

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

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

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

(c)  Pursuant to Section 3803(a) of the Business Trust Act, the Holders of the
     Preferred Securities shall be entitled to the same limitation of personal
     liability 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

                                       46
<PAGE>

     the Trust and in a manner such Indemnified Person reasonably believed to be
     within the scope of the authority conferred on such Indemnified Person by
     this Declaration or by law, except that an Indemnified Person shall be
     liable for any such loss, damage or claim incurred by reason of such
     Indemnified Person's gross negligence (or, in the case of the Property
     Trustee, negligence) or willful misconduct with respect to such acts or
     omissions.

(b)  An Indemnified Person shall be fully protected in relying in good faith
     upon the records of the Trust and upon 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
     Declaration shall not be liable to the Trust or to any other Covered Person
     for its good faith reliance on the provisions of this Declaration. The
     provisions of this Declaration, to the extent that they restrict the duties
     and liabilities of an Indemnified Person otherwise existing at law or in
     equity (other than the duties imposed on the 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 an
             Indemnified Person and any Covered Person; or

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

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

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

                                       47
<PAGE>

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

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

Section 10.04   Indemnification.

(a)  To the fullest extent permitted by applicable law, the Debenture Issuer
     shall indemnify and hold harmless each Indemnified Person from and against
     any loss, damage, liability, tax, penalty, expense or claim of any kind or
     nature whatsoever incurred by such Indemnified Person by reason of the
     creation, operation or termination of the Trust or 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 authority conferred on such Indemnified Person by this
     Declaration, except that no Indemnified Person shall be entitled to be
     indemnified in respect of any loss, damage or claim incurred by such
     Indemnified Person by reason of gross negligence (or, in the case of the
     Property Trustee, negligence) or willful misconduct with respect to such
     acts or omissions.

(b)  To the fullest extent permitted by applicable law, expenses (including
     legal fees and expenses) incurred by an Indemnified Person in defending any
     claim, demand, action, suit or proceeding shall, from time to time, be
     advanced by the Debenture Issuer prior to the final disposition of such
     claim, demand, action, suit or proceeding upon receipt by the Debenture
     Issuer of an undertaking by or on behalf of the Indemnified Person to repay
     such amount if it shall be determined that the Indemnified Person is not
     entitled to be indemnified as authorized in Section 10.4(a). The
     indemnification shall survive the termination of this Declaration or the
     resignation or removal of the Property Trustee or the Delaware Trustee, as
     the case may be.

Section 10.05   Outside Businesses.

     Any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee (subject to Section 5.03(c)) may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Trust, and the Trust and
the Holders of Securities shall have no rights by virtue of this Declaration in
and to such independent ventures or the income or profits derived therefrom and
the pursuit of any such venture, even if competitive with the business of the
Trust, shall not be deemed wrongful or improper. None of the Sponsor, any
Covered Person, 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

                                       48

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.

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 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 statements
     within 30 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, 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 Debentures held by the Property Trustee shall be made directly to
the Property Trustee Account and no other funds of the

                                       49
<PAGE>

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 Administrative Trustees on behalf of the Trust shall comply with all
withholding requirements under United States federal, state 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 on behalf of the Trust to assist it in determining the extent of, and
in fulfilling, its 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 claimed overwithholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust (at the
written direction of one of the Administrative Trustees of the Trust) may reduce
subsequent Distributions by the amount of such withholding.

                                   ARTICLE XII

                            Amendments and Meetings

Section 12.01   Amendments.

(a)  This Declaration may be amended from time to time by the Sponsor, the
     Property Trustee and the Administrative Trustees, without the consent of
     the Holders of the Securities, (i) to cure any ambiguity, correct or
     supplement any provision in the Declaration that may be inconsistent with
     any other provision, or to make any other provisions with respect to
     ministerial matters or questions arising under the Declaration, which shall
     not be inconsistent with the other provisions of the Declaration, or (ii)
     to modify, eliminate or add to any provisions of the Declaration to such
     extent as shall be necessary to ensure that the Trust will not be taxable
     as a corporation or 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 the case of clause (i), such action shall not adversely
     affect in any material respect the interests of any Holder of Securities,
     and any such amendments of the Declaration shall become effective when
     notice thereof is given to the Holders of the Securities.

(b)  Except as provided in (c) below, this Declaration may be amended by the
     Trustees and the Sponsor with (i) the consent of Holders representing not
     less than a Majority in liquidation amount of the outstanding Preferred
     Securities, and (ii) receipt by the Trustees of an opinion of counsel to
     the effect that such amendment or the exercise of any power granted to the

                                       50
<PAGE>

     Trustees in accordance with such amendment will not affect the 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.

(c)  Without the consent of each holder of Securities, the Declaration may not
     be amended to (i) change the amount or timing of any Distribution on the
     Securities or otherwise adversely affect the amount of any Distribution
     required to be made in respect of the Securities 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.

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
     Declaration, the terms of the Securities or the rules of any stock exchange
     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 25% in liquidation amount
     of such class of Securities. Such direction shall be given by delivering to
     the Administrative Trustees one or more requests in a writing stating that
     the signing Holders of Securities wish to call a meeting and indicating the
     general or specific purpose for which the meeting is to be called. Any
     Holders of Securities calling a meeting shall specify in writing the
     Certificates held by the Holders of Securities exercising the right to call
     a meeting and only those Securities represented by the Certificates so
     specified shall be counted for purposes of determining whether the required
     percentage set forth in the second sentence of this paragraph has been met.

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

        (i)  notice of any such meeting shall be given to all the Holders of
             Securities having a right to vote thereat at least 7 days and not
             more than 60 days before the date of such meeting. Whenever a vote,
             consent or approval of the Holders of Securities is permitted or
             required under this Declaration or the rules of any stock exchange
             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
             and without prior notice if a consent in writing setting forth the
             action so taken is signed by the Holders of Securities owning not
             less than the minimum aggregate liquidation amount of Securities
             that would be necessary to authorize or take such action at a
             meeting at which all Holders of Securities having a right to vote
             thereon were present and voting. Prompt notice of the taking of
             action without a meeting shall be given to the Holders of
             Securities entitled to vote who have not consented in writing. The
             Administrative Trustees may specify that any written ballot
             submitted to the 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;

                                       51
<PAGE>

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

        (iii) each meeting of the Holders of the Securities shall be conducted
              by the Administrative Trustees or by such other Person that the
              Administrative Trustees may designate; and

        (iv)  unless the Business Trust Act, this Declaration, the terms of the
              Securities, the Trust Indenture Act or the listing rules of any
              stock exchange on which the Preferred Securities are then listed
              or trading, provide otherwise, the Administrative Trustees, in
              their sole discretion, shall establish all other provisions
              relating to meetings of Holders of Securities, including notice of
              the time, place or purpose of any meeting at which any matter is
              to be voted on by any Holders of Securities, waiver of any such
              notice, action by consent without a meeting, the establishment of
              a record date, quorum requirements, voting in person or by proxy
              or any other matter with respect to the exercise of any such right
              to vote.

                TERMS OF 7 1/4% CONVERTIBLE PREFERRED SECURITIES
                TERM INCOME DEFERABLE EQUITY SECURITIES (TIDES)(SM)
                      7 1/4% CONVERTIBLE COMMON SECURITIES

     Pursuant to Section 7.01 of the Amended and Restated Declaration of Trust,
dated as of December 15, 1999 (as amended from time to time, the "Declaration"),
the designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Preferred Securities and the Common Securities are set out
below (each capitalized term used but not defined herein has the meaning set
forth in the Declaration or the Indenture (as defined in the Declaration) or, if
not defined in the Declaration or Indenture, as defined in the Offering Circular
(as defined in the Declaration):

1.   Designation and Number.

     (a) "Preferred Securities."  1,725,000 Preferred Securities of the Trust
with an aggregate liquidation preference with respect to the assets of the Trust
of Eighty-Six Million Two Hundred Fifty Thousand Dollars ($86,250,000), and a
liquidation amount with respect to the assets of the Trust of $50  per Preferred
Security, are hereby designated for the purposes of identification only as
"7 1/4% Convertible Preferred Securities, Term Income Deferrable Equity
Securities (TIDES)(SM)" (the "Preferred Securities"). The Preferred Security
Certificates evidencing the Preferred Securities shall be substantially in the
form attached hereto as Exhibit A-1, 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 other organization on which the
Preferred Securities are listed.

     (b) "Common Securities." 53,351 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of Two
Million Six Hundred Sixty-Seven Thousand Five Hundred Fifty Dollars ($2,667,550)
and a liquidation amount with respect to the assets of the Trust of $50 per
Common Security, are hereby designated for the purposes of identification only
as "7 1/4% Convertible Common Securities" (the "Common Securities"). The Common
Security Certificates evidencing the Common Securities shall be substantially in
the form attached hereto as Exhibit A-2, with such changes and additions thereto
or deletions therefrom as may be required by ordinary usage, custom or practice.

2.   Distributions.

     (a) Distributions payable on each Security will be fixed at a rate per
annum of 7 1/4% (the "Coupon Rate") of the stated liquidation amount of $50 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee. Distributions in arrears for more than one quarter
will bear interest thereon compounded quarterly at the Coupon Rate (to the
extent permitted by applicable law), subject to adjustment in the event of a
Registration Default, as described in the Declaration. The term "Distributions"
as used herein includes such quarterly distributions, additional distributions
on quarterly distributions not paid on the applicable Distribution Date, Special
Distributions and Additional Sums, as applicable. A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of

                                       1
<PAGE>

Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 30-day month.

     (b) Distributions on the Securities will be cumulative, will accrue from
the date of their original issuance and will be payable quarterly in arrears, on
the following dates, which dates correspond to the interest payment dates on the
Debentures: March 15, June 15, September 15 and December 15 of each year,
commencing on March 15, 2000, except as otherwise described below. The Sponsor
has the right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters (each a "Deferral Period") and, as a
consequence of such deferral, Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Deferral Period. Prior to three Business Days before a
Regular Record Date fixed for a Payment Resumption Date (as defined in the
Indenture), the Sponsor may further extend such Deferral Period; provided that
such Deferral Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters or extend beyond the maturity
(whether at the stated maturity or by declaration of acceleration, call for
redemption or otherwise) of the Debentures under the Indenture. Payments of
accrued Distributions will be payable to Holders as they appear on the books and
records of the Trust on the Regular Record Date for the relevant Payment
Resumption Date. Upon the termination of any Deferral Period and the payment of
all amounts then due, the Sponsor may commence a new Deferral Period, subject to
the above requirements.

     (c) Distributions on the Securities will be payable to the Holders thereof
as they appear on the books and records of the Trust at the close of business on
the relevant record dates. The relevant record dates shall be on the 1st day of
the month of the relevant payment dates, except as otherwise described in this
Annex I to the Declaration. Subject to any applicable laws and regulations and
the provisions of the Declaration, each such payment in respect of Preferred
Securities being held in book-entry form through The Depository Trust Company
(the "Depositary") will be made as described under the heading "Description of
TIDES -- Form, Book-Entry Procedures and Transfer" in the Offering Circular. The
relevant record dates for the Common Securities shall be the same record dates
as for the Preferred Securities. Distributions payable on any Securities that
are not punctually paid on any Distribution payment date, as a result of the
Sponsor having failed to make a payment under the Debentures, will cease to be
payable to the Person in whose name such Securities are registered on the
relevant record date, and such defaulted Distribution will instead be payable to
the Person in whose name such Securities are registered on the special record
date or other specified date determined in accordance with the Indenture. If any
date on which Distributions are payable on the Securities is not a Business Day,
then payment of the Distribution payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, with respect to any Redemption Date,
if such Business Day is in the next succeeding calendar year, such Redemption
Date shall be the immediately preceding Business Day, in each case with the same
force and effect as if made on such date.

                                       2
<PAGE>

     (d) In the event of an election by the Holder to convert its Securities
through the Conversion Agent into Common Stock pursuant to the terms of the
Securities as forth in this Annex I to the Declaration, no payment, allowance or
adjustment shall be made with respect to accumulated and unpaid Distributions on
such Securities, or be required to be made; provided that Holders of Securities
at the close of business on any record date for the payment of Distributions
will be entitled to receive the Distributions payable on such Securities on the
corresponding payment date notwithstanding the conversion of such Securities
into Common Stock following such record date.

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

3.   Liquidation Distribution Upon Dissolution.

     In the event of any voluntary or involuntary dissolution of the Trust, the
Trust shall be liquidated by the Trustees as expeditiously as the Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law (including, without
limitation, by paying or making reasonable provision to pay all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act), to the Holders of the Securities a Like Amount of Debentures, unless
such distribution would not be practical as determined by the Administrative
Trustees, in which event such Holders will be entitled to receive out of the
assets of the Trust available for distribution to holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law (including,
without limitation, by paying or making reasonable provision to pay all claims
and obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act), an amount equal to, in the case of Holders of Preferred Securities,
the aggregate liquidation amount thereof plus accrued and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"). If such Liquidation Distribution can be paid only in part
because the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by the Trust on the
Preferred Securities shall be paid on a Pro Rata (as defined below) basis in
accordance with paragraph 9. The Holder of the Common Securities will be
entitled to receive distributions upon any such liquidation Pro Rata with the
Holders of the Preferred Securities, except as provided in paragraph 10.

4.   Redemption and Distribution.

     (a) Upon the repayment or payment of the Debentures in whole or in part,
whether at maturity or upon redemption or otherwise (other than following any
distribution of the Debentures to the Holders), the proceeds from such repayment
or redemption shall be simultaneously applied to redeem, on a Pro Rata basis, a
Like Amount of Securities, on the redemption date, in an amount per Security
equal to the applicable redemption price, which redemption price will be equal
to (i) the liquidation amount of each of the Securities plus any accrued and
unpaid Distributions thereon (A) in the case of the repayment of the Debentures
at stated maturity, or (B) in the case of a redemption of the Debentures in
certain limited circumstances set forth in the Indenture upon the occurrence of
a Tax Event or (ii) in the case of an Optional Redemption on or after December
20, 2002, the Optional Redemption Price (as defined in the Indenture), payable
in cash (as applicable, the "Redemption Price"). Holders will be given not less
than 20 nor more than 60 days' notice of such

                                       3
<PAGE>

redemption. Upon the repayment of the Debentures at maturity or upon any
acceleration, earlier redemption or otherwise, the proceeds from such repayment
will be applied to redeem the Securities, in whole, upon not less than 30 nor
more than 60 days' notice.

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

     (c) The Sponsor, as the Holder of the outstanding Common Securities, shall
have the right at any time (including, without limitation, upon the occurrence
of a Tax Event or Investment Company Act Event) to dissolve the Trust and, after
satisfaction of the creditors of the Trust, cause a Like Amount of the
Debentures to be distributed to the Holders of the Securities upon liquidation
of the Trust, provided that the Administrative Trustees shall have received a No
Recognition Opinion (as defined below) prior to the dissolution of the Trust.

     (d) If, at any time, a Tax Event shall occur and be continuing the Sponsor
shall cause the Administrative Trustees to dissolve the Trust and, after
satisfaction of creditors of the Trust (including, without limitation, by paying
or making reasonable provision to pay all claims and obligations of the Trust in
accordance with Section 3808(e) of the Business Trust Act), cause Debentures to
be distributed to the Holders of the Securities in liquidation of the Trust
within 90 days following the occurrence of such Tax Event (the "90 Day Period");
provided, however, that such dissolution and distribution shall be conditioned
on (i) the Trustees' receipt of an opinion of a nationally recognized
independent tax counsel (reasonably acceptable to the Trustees) experienced in
such matters (a "No Recognition Opinion"), which opinion may rely on published
revenue rulings of the Internal Revenue Service, to the effect that the Holders
of the Securities will not recognize any income, gain or loss for United States
federal income tax purposes as a result of such liquidation and distribution of
Debentures, and (ii) the Sponsor being unable to avoid such Tax Event within the
90 day period by taking some ministerial action or pursuing some other
reasonable measure that, in the sole judgment of the Sponsor, will have no
adverse effect on the Trust, the Sponsor or the Holders of the Securities and
will involve no material cost ("Ministerial Action").

     If (i) the Sponsor has received an opinion (a "Redemption Tax Opinion") of
a nationally recognized independent tax counsel (reasonably acceptable to the
Trustees) experienced in such matters that, as a result of a Tax Event, there is
more than an insubstantial risk that the Sponsor would be precluded from
deducting the interest on the Debentures for United States federal income tax
purposes, even after the Debentures were distributed to the Holders of
Securities upon liquidation of the Trust as described in this paragraph 4(d), or
(ii) the Trustees shall have been informed by such tax counsel that it cannot
deliver a No Recognition Opinion, the Sponsor shall have the right, upon not
less than 20 nor more than 60 days' notice, and within 90 days following the
occurrence of such Tax Event, to redeem the Debentures in whole (but not in
part) for cash, for the principal amount plus accrued and unpaid interest
thereon and, following such redemption, all the Securities will be redeemed by
the Trust at the liquidation amount of $50 per Security plus accrued and unpaid
Distributions thereon; provided, however, that, if at the time there is
available to the Sponsor or the Trust the opportunity to eliminate, within the
90 Day Period, the Tax Event by taking some Ministerial Action, the Trust or the
Sponsor will pursue such Ministerial Action in lieu of redemption.


                                       4
<PAGE>

     In lieu of the foregoing options, the Company shall also have the option of
causing the Securities to remain outstanding and pay Additional Sums on the
Debentures.

    "Tax Event" means that the Property Trustee shall have received an opinion
of a nationally recognized independent tax counsel to the Sponsor (reasonably
acceptable to the Trustees) experienced in such matters (a "Dissolution Tax
Opinion") to the effect that, as a result of (i) any amendment to, or change
(including any announced prospective change (which shall not include a proposed
change), provided that a Tax Event shall not occur more than 90 days before the
effective date of any such prospective change) in the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority therefor or therein, (ii) any judicial decision or official
administrative pronouncement, ruling, regulatory procedure, notice or
announcement, including any notice or announcement of intent to adopt such
procedures or regulations (an "Administrative Action") or (iii) any amendment to
or change in the administrative position or interpretation of any Administrative
Action or judicial decision that differs from the theretofore generally accepted
position, in each case, by any legislative body, court, governmental agency or
regulatory body, irrespective of the manner in which such amendment or change is
made known, which amendment or change is effective or such Administrative Action
or decision is announced, in each case, on or after the date of original
issuance of the Debentures or the issue date of the Preferred Securities issued
by the Trust, there is more than an insubstantial risk that (a) if the
Debentures are held by the Property Trustee, (I) the Trust is, or will be within
90 days of the date of such opinion, subject to United States federal income tax
with respect to interest accrued or received on the Debentures or subject to
more than a de minimis amount of other taxes, duties or other governmental
charges as determined by such counsel, or (II) any portion of interest payable
by the Sponsor to the Trust on the Debentures is not, or within 90 days of the
date of such opinion will not be, deductible by the Sponsor in whole or in part
for United States federal income tax purposes or (b) with respect to Debentures
which are no longer held by the Property Trustee, any portion of interest
payable by the Sponsor on the Debentures is not, or within 90 days of the date
of such opinion will not be, deductible by the Sponsor in whole or in part for
United States federal income tax purposes.

     If an Investment Company Event (as hereinafter defined) shall occur and be
continuing, the Sponsor shall cause the Trustees to dissolve the Trust and,
after satisfaction of liabilities of the creditors of the Trust as provided by
applicable law (including, without limitation, by paying or making reasonable
provision to pay all claims and obligations of the Trust in accordance with
Section 3808(e) of the Business Trust Act), cause the Debentures to be
distributed to the Holders of the Securities in liquidation of the Trust within
90 days following the occurrence of such Investment Company Event.

    "Investment Company Event" means the occurrence of a change in law or
regulation or a written change in interpretation or application of law or
regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), to the effect that the Trust is or will
be considered an Investment Company which is required to be registered under the
Investment Company Act, which Change in 1940 Act Law becomes effective on or
after the date of the Offering Circular.

     After the date fixed for any distribution of Debentures: (i) the Securities
will no longer be deemed to be outstanding, (ii) the Depositary or its nominee
(or any successor Depositary or its

                                       5
<PAGE>

nominee), as record Holder of Preferred Securities represented by global
certificates, will receive a registered global certificate or certificates
representing the Debentures to be delivered upon such distribution and (iii) any
certificates representing Securities, except for certificates representing
Preferred Securities held by the Depositary or its nominee (or any successor
Depositary or its nominee), will be deemed to represent Debentures having an
aggregate principal amount equal to the aggregate stated liquidation amount of
such Securities, with accrued and unpaid interest equal to accrued and unpaid
Distributions on such Securities until such certificates are presented to the
Sponsor or its agent for transfer or reissuance.

     (e) The Securities will not be redeemed unless all accrued and unpaid
Distributions have been paid on all Securities for all quarterly Distribution
periods terminating on or before the date of redemption.

     (f) Redemption or Distribution Procedures.

         (i) Notice of any redemption of, or notice of distribution of
     Debentures in exchange for the Securities (a "Redemption/Distribution
     Notice") will be given any an Administrative Trustee on behalf of the Trust
     by mail to each Holder of Securities to be redeemed or exchanged not fewer
     than 20 nor more than 60 days before the date fixed for redemption or
     exchange thereof which, in the case of a redemption, will be the date fixed
     for redemption of the Debentures. For purposes of the calculation of the
     date of redemption or exchange and the dates on which notices are given
     pursuant to this paragraph 4(f)(i), a Redemption/Distribution Notice shall
     be deemed to be given on the day such notice is first mailed by first-class
     mail, postage prepaid, to Holders of Securities. Each
     Redemption/Distribution Notice shall be addressed to the Holders of
     Securities at the address of each such Holder appearing in the books and
     records of the Trust. No defect in the Redemption/Distribution Notice or in
     the mailing of either thereof with respect to any Holder shall affect the
     validity of the redemption or exchange proceedings with respect to any
     other Holder.

         (ii) In the event that fewer than all the outstanding Securities are to
     be redeemed, the Securities to be redeemed shall be redeemed Pro Rata from
     each Holder of Preferred Securities, it being understood that, in respect
     of Preferred Securities registered in the name of and held of record by the
     Depositary (or any successor Depositary) or any nominee, the distribution
     of the proceeds of such redemption will be made to each Participant (or
     Person on whose behalf such nominee holds such securities) in accordance
     with the procedures applied by such agency or nominee.

         (iii) If Securities are to be redeemed and an Administrative Trustee on
     behalf of the Trust gives a Redemption/Distribution Notice, which notice
     may only be issued if the Debentures are redeemed as set out in this
     paragraph 4 (which notice will be irrevocable), then (A) with respect to
     Preferred Securities held in book-entry form, by 12:00 noon, New York City
     time, on the redemption date, to the extent funds are available, with
     respect to Preferred Securities held in global form, the Property Trustee
     will deposit irrevocably with the Depositary (or successor Depositary)
     funds sufficient to pay the amount payable on redemption with respect to
     such Preferred Securities and will give the Depositary

                                       6
<PAGE>

     irrevocable instructions and authority to pay the amount payable on
     redemption to the Holders of such Preferred Securities, and (B) with
     respect to Preferred Securities issued in certificated form and Common
     Securities, to the extent funds are available, the Property Trustee will
     irrevocably deposit with the Paying Agent funds sufficient to pay the
     amount payable on redemption to the Holders of such Securities and will
     give the Paying Agent irrevocable instructions and authority to pay the
     amount payable on redemption to the Holders thereof upon surrender of their
     certificates. If a Redemption/Distribution Notice shall have been given and
     funds deposited as required, then on the date of such deposit, all rights
     of Holders of such Securities so called for redemption will cease, except
     the right of the Holders of such Securities to receive the redemption
     price, but without interest on such redemption price, and such Securities
     will cease to be outstanding. Neither the Administrative Trustees nor the
     Property Trustee shall be required to register or cause to be registered
     the transfer of any Securities that have been so called for redemption. If
     any date fixed for redemption of Securities is not a Business Day, then
     payment of the amount payable on such date will be made on the next
     succeeding day that is a Business Day (without any interest or other
     payment in respect of any such delay) except that, if such Business Day
     falls in the next calendar year, such payment will be made on the
     immediately preceding Business Day, in each case with the same force and
     effect as if made on such date fixed for redemption. If payment of the
     redemption price in respect of any Securities is improperly withheld or
     refused and not paid either by the Trust or by the Sponsor as guarantor
     pursuant to the relevant Securities Guarantee, Distributions on such
     Securities will continue to accrue at the then applicable rate, from the
     original redemption date to the date of payment, in which case the actual
     payment date will be considered the date fixed for redemption for purposes
     of calculating the amount payable upon redemption (other than for purposes
     of calculating any premium).

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

         (v) Subject to the foregoing 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.

5.   Conversion Rights.

     The Holders of Securities shall have the right at any time prior to 5:00
p.m. New York City Time on the Business Day immediately preceding the earlier of
December 15, 2029 and the date fixed for redemption of the Securities, at their
option, to cause the Conversion Agent to convert Securities, on behalf of the
converting Holders, into shares of  Common Stock, par value $.001 per share, of
the Sponsor (the "Common Stock") in the manner described herein on and subject
to the following terms and conditions:

                                       7
<PAGE>

     (a) The Securities will be convertible at the office of the Conversion
Agent into fully paid and nonassessable shares of Common Stock pursuant to the
Holder's direction to the Conversion Agent to exchange such Securities for a
portion of the Debentures theretofore held by the Trust on the basis of one
Security per $50 principal amount of Debentures, and immediately convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock at
an initial rate of 1.3986 shares of Common Stock per $50 principal amount of
Debentures (which is equivalent to a conversion price of $35.75 per share of
Common Stock, subject to certain adjustments set forth in the Indenture).

     (b) In order to convert Securities into Common Stock the Holder shall
submit to the Conversion Agent at the office referred to above an irrevocable
request to convert Securities on behalf of such Holder (the "Conversion
Request"), together, if the Securities are in certificated form, with such
certificates. The Conversion Request shall (i) set forth the number of
Securities to be converted and the name or names, if other than the Holder, in
which the shares of Common Stock should be issued and (ii) direct the Conversion
Agent (a) to exchange such Securities for a portion of the Debentures held by
the Trust (at the rate of exchange specified in the preceding paragraph) and (b)
to immediately convert such Debentures on behalf of such Holder, into Common
Stock (at the conversion rate specified in the preceding paragraph). The
Conversion Agent shall notify the Trust of the Holder's election to exchange
Securities for a portion of the Debentures held by the Trust and the Trust
shall, upon receipt of such notice, deliver to the Conversion Agent the
appropriate principal amount of Debentures for exchange in accordance with this
Section. The Conversion Agent shall thereupon notify the Sponsor of the Holder's
election to convert such Debentures into shares of Common Stock. Holders of
Securities at the close of business on a Distribution record date will be
entitled to receive the Distribution payable on such Securities on the
corresponding Distribution payment date notwithstanding the conversion of such
Securities following such record date but prior to such distribution payment
date. Except as provided above, neither the Trust nor the Sponsor will make, or
be required to make, any payment, allowance or adjustment upon any conversion on
account of any accumulated and unpaid Distributions accrued on the Securities,
whether or not in arrears, (including any Additional Amounts accrued thereon)
surrendered for conversion, or on account of any accumulated and unpaid
dividends on the shares of Common Stock issued upon such conversion, except to
the extent that such shares are held of record on the record date for any such
distributions. Securities shall be deemed to have been converted immediately
prior to the close of business on the day on which a Notice of Conversion
relating to such Securities is received by the Trust in accordance with the
foregoing provision (the "Conversion Date"). The Person or Persons entitled to
receive the Common Stock issuable upon conversion of the Debentures shall be
treated for all purposes as the record holder or holders of such Common Stock at
such time. As promptly as practicable on or after the Conversion Date, the
Sponsor shall issue and deliver at the office of the Conversion Agent a
certificate or certificates for the number of full shares of Common Stock
issuable upon such conversion, together with the cash payment, if any, in lieu
of any fraction of any share to the Person or Persons entitled to receive the
same, unless otherwise directed by the Holder in the notice of conversion and
the Conversion Agent shall distribute such certificate or certificates to such
Person or Persons.

     (c) Each Holder of a Security by his acceptance thereof appoints Wilmington
Trust Company "Conversion Agent" for the purpose of effecting the conversion of
Securities in accordance with this Section. In effecting the conversion and
transactions described in this Section,

                                       8
<PAGE>

the Conversion Agent shall be acting as agent of the Holders of Securities
directing it to effect such conversion transactions. The Conversion Agent is
hereby authorized (i) to exchange Securities from time to time for Debentures
held by the Trust in connection with the conversion of such Securities in
accordance with this Section and (ii) to convert all or a portion of the
Debentures into Common Stock and thereupon to deliver such shares of Common
Stock in accordance with the provisions of this Section and to deliver to the
Trust a new Debenture or Debentures for any resulting unconverted principal
amount.

     (d) No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, such fractional interest will be paid in cash
by the Sponsor to the Trust, which in turn will make such payment to the Holder
or Holders of Securities so converted.

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

     (f) The Sponsor will pay any and all taxes that may be payable in respect
of the issue or delivery of shares of Common Stock on conversion of Debentures
and the delivery of the shares of Common Stock upon conversion of the
Securities. The Sponsor shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of
shares of Common Stock in a name other than that in which the Securities so
converted were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Sponsor the amount of
any such tax, or has established to the satisfaction of the Sponsor that such
tax has been paid.

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

6.   Voting Rights--Preferred Securities.

                                       9
<PAGE>

     (a) Except as provided under paragraphs 6(b) and 8, in the Business Trust
Act and as otherwise required by law, the Declaration and the Indenture, the
Holders of the Preferred Securities will have no voting rights.

     (b) In addition to the rights of the Holders of the Preferred Securities
with respect to the enforcement of payment of principal and interest on the
Debentures set forth herein, in the Declaration or in the Indenture, if (i) a
Debenture Event of Default occurs and is continuing or (ii) the Company defaults
under the Guarantee (each of (i) and (ii) being an "Appointment Event"), then
the Holders of the Preferred Securities, acting as a single class, will be
entitled by the vote of a Majority in liquidation amount of the Preferred
Securities to appoint a  Special Trustee in accordance with Section
5.06(a)(ii)(B) of the Declaration. Any Holder of Preferred Securities (other
than the Sponsor, or any entity directly or indirectly controlling or controlled
by or under direct or indirect common control with the Sponsor) will be entitled
to nominate any Person to be appointed as Special Trustee. Not later than 30
days after such right to appoint a Special Trustee arises, the Trustees will
convene a meeting for the purpose of appointing a Special Trustee. If the
Trustees fail to convene such meeting within such 30-day period, the Holders of
not less than 10% in aggregate liquidation amount of the Preferred Securities
will be entitled to convene such meeting in accordance with Section 12.02 of the
Declaration. The record date for such meeting will be the close of business on
the Business Day that is one Business Day before the day on which notice of the
meeting is sent to the Holders. The provisions of the Declaration relating to
the convening and conduct of the meetings of the Holders will apply with respect
to any such meeting.

     Any Special Trustee so appointed shall cease to be a Special Trustee if the
Appointment Event pursuant to which the Special Trustee was appointed and all
other Appointment Events cease to be continuing. A Special Trustee may be
removed without cause at any time by vote of the Holders of a Majority in
liquidation amount of the Preferred Securities at a meeting of the Holders of
the Preferred Securities or by written consent in accordance with Section
5.06(a)(ii)(B) of the Declaration. The Holders of 10% in liquidation amount of
the Preferred Securities will be entitled to convene such a meeting in
accordance with Section 12.02 of the Declaration. The record date for such
meeting will be the close of business on the Business Day which is one Business
Day before the day on which the notice of meeting is sent to Holders.
Notwithstanding the appointment of a Special Trustee, the Sponsor shall retain
all rights under the Indenture, including the right to defer payments of
interest by extending the interest payment period on the Debentures.

     Subject to the requirements set forth in this paragraph, the Holders of a
majority in liquidation amount of the Preferred Securities, voting separately as
a class may, and the Trustees shall not, without obtaining the prior approval of
the Holders of a Majority in aggregate liquidation amount of all outstanding
Preferred Securities (i) direct the time, method, and place of conducting any
proceeding for any remedy available to the Trustee under the Indenture, or
executing any trust or power conferred upon the Property Trustee with respect to
the Debentures, (ii) waive any past default and its consequences that is
waivable under Section 5.13 of the Indenture or otherwise, (iii) exercise any
right to rescind or annul a declaration that the principal of all the Debentures
shall be due and payable or (iv) consent to any amendment, modification or
termination of the Indenture or the Debentures, where such consent shall be
required, provided, however, that, where a consent under the Indenture would
require the consent or act of the Holders of greater than a majority of the
Holders in principal amount of Debentures affected thereby (a "Super Majority"),
the Property

                                      10
<PAGE>

Trustee may only give such consent or take such action at the
direction of the Holders of at least the proportion in liquidation preference of
the Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding. The Property Trustee
shall not, and none of the other Trustees shall in any event, revoke any action
previously authorized or approved by a vote of the Holders of the Preferred
Securities, except by a subsequent vote of the Holders of the Preferred
Securities. Other than with respect to directing the time, method and place of
conducting any remedy available to the Property Trustee or the Debenture Trustee
as set forth above, the Property Trustee shall not take any action in accordance
with the directions of the Holders of the Preferred Securities under this
paragraph unless the Property Trustee has obtained an opinion of tax counsel to
the effect that, as a result of such action, the Trust will not fail to be
classified as a grantor trust for United States federal income tax purposes.

     If a Declaration Event of Default has occurred and is continuing and such
event is attributable to the failure of the Debenture Issuer to pay interest or
principal on the Debentures on the date such interest or principal is otherwise
payable (or in the case of redemption on the redemption date), then a Holder of
Preferred Securities may directly institute a proceeding for enforcement of
payment to such Holder (a "Direct Action") of the principal of or interest on
the Debentures having a principal amount equal to the aggregate liquidation
amount of the Preferred Securities of such Holder on or after the respective due
date specified in the Debentures. Except as provided in the preceding sentence,
the Holders of Preferred Securities will not be able to exercise directly any
other remedy available to the Holders of the Debentures. In connection with any
Direct Action, the Debenture Issuer will be subrogated to the rights of such
Holder of Preferred Securities under the Declaration to the extent of any
payment made by the Debenture Issuer to such Holder of Preferred Securities in
such Direct Action.

     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
without notice pursuant to written consent. The Administrative 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 the following
information (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 Debentures in accordance with the Declaration 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

7.   Voting Rights--Common Securities.


                                      11
<PAGE>

     (a) Except as provided under paragraphs 7(b), (c) and 8, in the Business
Trust Act and as otherwise required by law and the Declaration, the Holders of
the Common Securities will have no voting rights.

     (b) The Holders of the Common Securities are entitled, in accordance with
Article V of the Declaration, to vote to appoint, remove or replace any Trustee,
subject to the exclusive right of the Holders of the Preferred Securities to
appoint, remove or replace a Special Trustee.

     (c) Subject to Section 2.06 of the Declaration and only after the Event of
Default with respect to the Preferred Securities has been cured, waived, or
otherwise eliminated and subject to the requirements of the second to last
sentence of this paragraph, the Holders of a Majority in liquidation amount of
the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee, or exercising any trust or power conferred upon the Property
Trustee under the Declaration, including (i) directing the time, method, place
of conducting any proceeding for any remedy available to the Debenture Trustee,
or exercising any trust or power conferred on the Debenture Trustee with respect
to the Debentures, (ii) waive any past default and its consequences that is
waivable under Section 5.13 of the Indenture, or (iii) exercise any right to
rescind or annul a declaration that the principal of all the Debentures shall be
due and payable, provided that, where a consent or action under the Indenture
would require the consent or act of the Holders of greater than a majority in
principal amount of Debentures affected thereby (a "Super Majority"), the
Property Trustee may only give such consent or take such action at the direction
of the Holders of at least the proportion in liquidation amount of the Common
Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding. Pursuant to this paragraph 7(c),
the Property Trustee shall not revoke any action previously authorized or
approved by a vote of the Holders of the Preferred Securities, except by a
subsequent vote of the Holders of the Preferred Securities. Other than with
respect to directing the time, method and place of conducting any remedy
available to the Property Trustee or the Debenture Trustee as set forth above,
the Property Trustee shall not take any action in accordance with the directions
of the Holders of the Common Securities under this paragraph unless the Property
Trustee has obtained an opinion of tax counsel to the effect that, as a result
of such action the Trust will not fail to be classified as a grantor trust for
United States federal income tax purposes. If the Property Trustee fails to
enforce its rights, as holder of the Debentures, under the Indenture, any Holder
of Common Securities may, to the fullest extent permitted by law and after a
period of 30 days has elapsed from such Holder's written request to the Property
Trustee to enforce such rights, institute a legal proceeding directly against
the Sponsor, to enforce the Property Trustee's rights, as holder of the
Debentures, under the Indenture, without first instituting any legal proceeding
against the Property Trustee or any other Person.

     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 without notice
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, (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.

                                      12
<PAGE>

     No vote or consent of the Holders of the Common Securities will be required
for the Trust to redeem and cancel Common Securities or to distribute the
Debentures in accordance with the Declaration and the terms of the Securities.

8.   Amendments to Declaration and Indenture.

     (a) In addition to any requirements under Section 12.01 of the Declaration,
if any proposed amendment to the Declaration provides for, or the Administrative
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers, preferences or rights of the Securities, whether by way of amendment
to the Declaration or otherwise, or (ii) the dissolution, winding-up or
termination of the Trust, other than as described in Section 8.01 of the
Declaration, then the Holders of outstanding Securities will be entitled to vote
on such amendment or proposal (but not on any other amendment or proposal) and
such amendment or proposal shall not be effective except with the approval of
the Holders of at least a Majority in liquidation amount of the Securities,
voting together as a single class, provided, however, that, the rights of
Holders of Preferred Securities under Article V of the Declaration to appoint,
remove or replace a Special Trustee shall not be amended without the consent of
each Holder of Preferred Securities; and provided further that if any amendment
or proposal referred to in clause (i) above would adversely affect only the
Preferred Securities or only the Common Securities, then only the affected class
will be entitled to vote on such amendment or proposal and such amendment or
proposal shall not be effective except with the approval of at least a Majority
in liquidation amount of such class of Securities.

     (b) In the event the consent of the Property Trustee as the holder of the
Debentures is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the Property
Trustee shall request the direction of the Holders of the Securities with
respect to such amendment, modification or termination and shall vote with
respect to such amendment, modification or termination as directed by at least
the same proportion in aggregate stated liquidation preference of the
Securities; provided, however, that the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Securities under
this paragraph 8(b) unless the Property Trustee has obtained an opinion of tax
counsel to the effect that for the purposes of United States federal income tax
the Trust will not be classified as other than a grantor trust on account of
such action.

9.   Pro Rata.

     A reference in these terms of the Securities to any payment, Distribution
or treatment as being "Pro Rata" shall mean pro rata to each Holder of
Securities according to the aggregate liquidation amount of the Securities held
by the relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, on any Distribution Date or redemption date an
Event of Default under the Declaration has occurred and is continuing, in which
case no payment of any Distribution on, or amount payable upon redemption of,
any Common Security, and no other payment on account of the redemption,
liquidation or other acquisition of Common Securities, shall be made unless
payment in full in cash of all accumulated and unpaid Distributions on all
outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the amount payable upon redemption
of the Preferred Securities, the full amount of such amount in respect of all
outstanding Preferred Securities shall have been made or provided


                                      13
<PAGE>

for, and all funds available to the Property Trustee shall first be applied to
the payment in full in cash of all Distributions on, or the amount payable upon
redemption of Preferred Securities then due and payable.

10.  Ranking.

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

11.  Acceptance of Securities Guarantees and Indenture.

     Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture which
are incorporated by reference herein and which include, among other things,
provisions relating to certain rights of the Holders of the Preferred Securities
all as set forth therein.

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 Declaration.

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

<PAGE>

                         [FORM OF REVERSE OF SECURITY]

     Distributions payable on each Preferred Security will be fixed at a rate
per annum of 7 1/4% (the "Coupon Rate") of the stated liquidation amount of $50
per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one quarter will bear interest thereon compounded quarterly at the Coupon
Rate (to the extent permitted by applicable law). The term "Distributions" as
used herein includes such quarterly distributions, additional distributions on
quarterly distributions not paid on the applicable Distribution Date, Special
Distributions and Additional Sums, as applicable. A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

     Except as otherwise described below, Distributions on the Preferred
Securities will be cumulative, will accrue from the date of their original
issuance and will be payable quarterly in arrears, on March 15, June 15,
September 15 and December 15 of each year, commencing on March 15, 2000, to
Holders of record at the close of business on the 1st day of the month of the
applicable payment date, which payment dates shall correspond to the interest
payment dates (each an "Interest Payment Date") on the Debentures. The Debenture
Issuer has the right under the Indenture to defer payments of interest by
extending the interest payment period from time to time on the Debentures for a
period not exceeding 20 consecutive quarters (each a "Deferral Period") and, as
a consequence of such deferral, Distributions will also be deferred. Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded quarterly during any such Deferral Period. Prior to the termination
of any such Deferral Period, the Debenture Issuer may further extend such
Deferral Period; provided that such Deferral Period together with all such
previous and further deferrals thereof may not exceed 20 consecutive quarters or
extend beyond the maturity (whether at the stated maturity or by declaration of
acceleration, call for redemption or otherwise) of the Debentures under the
Indenture. Payments of accrued Distributions will be payable on an Interest
Payment Date elected by the Company to Holders as they appear on the books and
records of the Trust on the record date fixed for such Interest Payment Date.
Upon the termination of any Deferral Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Deferral Period, subject to the
above requirements.

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

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

(the "Holder") is the registered owner of common securities of the Trust

Restated Declaration of Trust of the Trust dated as of December 15, 1999, as the
same may be amended from time to time (the "Declaration"), including the
designation of the terms of the Common Securities as set forth in Annex I to the
Declaration. Capitalized terms used herein but not defined shall have the

  Upon receipt of this certificate, the Sponsor is bound by the Declaration and

  By acceptance, the Holder agrees to treat for United States federal income tax

                                Hanover Compressor Capital Trust


                                By:
                                   --------------------------------
                                   Name:
                                   Title:

                                       2
<PAGE>

                         [FORM OF REVERSE OF SECURITY]

  Distributions payable on each Common Security will be fixed at a rate per
annum of 7 1/4% (the "Coupon Rate") of the stated liquidation amount of $50 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
quarter will bear interest thereon compounded quarterly at the Coupon Rate (to
the extent permitted by applicable law). The term "Distributions" as used herein
includes quarterly distributions, additional distributions on quarterly
distributions not paid on the applicable Distribution Date, Special
Distributions and Additional Sums, as applicable. A Distribution is payable only
to the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

  Except as otherwise described below, Distributions on the Common Securities
will be cumulative, will accrue from the date of their original issuance and
will be payable quarterly in arrears, on March 15, June 15, September 15 and
December 15 of each year, commencing on March 15, 2000, to Holders of record one
(1) day prior to such payment dates, which payment dates shall correspond to the
interest payment dates (each, an "Interest Payment Date") on the Debentures. The
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period from time to time on the Debentures for
a period not exceeding 20 consecutive quarters (each a "Deferral Period") and,
as a consequence of such deferral, Distributions will also be deferred. Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded quarterly during any such Deferral Period. Prior to the termination
of any such Deferral Period, the Debenture Issuer may further extend such
Deferral Period; provided that such Deferral Period together with all such
previous and further deferrals thereof may not exceed 20 consecutive quarters or
extend beyond the maturity (whether at the stated maturity or by declaration of
acceleration, call for redemption or otherwise) of the Debentures under the
Indenture. Payments of accrued Distributions will be payable on an Interest
Payment Date elected by the Company to Holders as they appear on the books and
records of the Trust on the record date fixed for such Interest Payment Date.
Upon the termination of any Deferral Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Deferral Period, subject to the
above requirements.

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

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

be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments is or are delivered to the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments (and the

                                      -11-
<PAGE>

action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 6.01)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

(b)  The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee or the Company, as the case may be, deems
sufficient.

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

(d)  The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to join in the giving or making
of (i) any notice of default, (ii) any declaration of acceleration referred to
in Section 5.02, (iii) any request to institute proceedings referred to in
Section 5.07(2) or (iv) any direction referred to in Section 5.12. If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities on
such record date, and no other Holders, shall be entitled to join in such
notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the date set by the Trustee by which any
such determination shall be made (the "Expiration Date") by Holders of the
requisite principal amount of Outstanding Securities on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting
a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities on the date such action is taken. Promptly after any record date is
set pursuant to this paragraph, the Trustee, at the Company's expense, shall
cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities in the manner set forth in Section 1.06.

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

                                      -12-
<PAGE>

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

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

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

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

(1)  the Trustee by any Holder or by the Company shall be sufficient for every
purpose hereunder if made, given, furnished or filed in writing to:

               Wilmington Trust Company
               1100 North Market Street
               Wilmington, Delaware 19890
               Attention:  Corporate Trust Administration

(2)  the Company by the Trustee or by any Holder shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing and
mailed, first-class postage prepaid, to the Company addressed to:

               Hanover Compressor Company
               12001 North Houston Rosslyn
               Houston, Texas 77086
               Attention:  Chief Financial Officer

Section 1.06  Notice to Holders; Waiver.

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

                                      -13-
<PAGE>

before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service or by reason
of any other cause, it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Section 1.07  Conflict with Trust Indenture Act.

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

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

its successors and assigns, whether so expressed or not.

Section 1.10  Separability Clause.

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

Section 1.11  Benefits of Indenture.

give to any Person, other than the parties hereto and their successors

convert his Securities shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal or conversion of the Securities need not be made on such date, but may
be made on the next succeeding Business Day (except that, with respect to any
Redemption Date, if such Business Day is in the next succeeding calendar year,
such Redemption Date shall be the immediately preceding Business Day) with the
same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity or on such last day for conversion, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

Section 2.04  Issuance of Global Securities to Holders.

     The Securities may be represented by one or more Global Securities
registered in the name of the Depositary or its nominee if, and only if, the
Securities are distributed to the Holders of the Trust Securities. Until such
time, the Securities shall be registered in the name of and held by the Property
Trustee. Securities distributed to Holders of book-entry Trust Securities shall
be distributed in the form of one or more Global Securities registered in the
name of the Depositary or its nominee, and deposited with the Security
Registrar, as custodian for such Depositary, or held by such Depositary for
credit by the Depositary to the respective accounts of the beneficial owners of
the Securities represented thereby (or such other accounts as they may direct).
Securities distributed to Holders of Trust Securities other than book-entry
Trust Securities shall not be issued in the form of a Global Security or any
other form intended to facilitate book-entry trading in beneficial interests in
such Securities.

                                  ARTICLE III

                                THE SECURITIES

Section 3.01  Title and Terms.

     The aggregate principal amount of Securities that may be authenticated and
delivered under this Indenture is limited to the sum of $88,917,550 except for
Securities authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, other Securities pursuant to Section 3.04, 3.05,
3.06, 3.07, 9.06, 11.07 or 13.02.

                                      -17-
<PAGE>

     The Securities shall be known and designated as the "7 1/4% Convertible
Junior Subordinated Debentures Due 2029" of the Company. Their Stated Maturity
shall be December 15, 2029, and they shall bear interest at the Applicable Rate,
from December 15, 1999 or from the most recent Interest Payment Date (as defined
below) to which interest has been paid or duly provided for, as the case may be,
payable quarterly (subject to deferral as set forth herein), in arrears, on
March 15, June 15, September 15 and December 15 (each an "Interest Payment
Date") of each year, commencing March 15, 2000, until the principal thereof is
paid or made available for payment, and they shall be paid to the Person in
whose name the Security is registered at the close of business on the regular
record date for such interest installment, which shall be the close of business
on the first day of the month of the applicable Interest Payment Date (the
"Regular Record Date"). Interest will compound quarterly and will accrue at the
Applicable Rate on any interest installment in arrears for more than one quarter
or during an extension of an interest payment period as set forth in Section
3.13 hereof.

     The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. Except as provided in the following
sentence, the amount of interest payable for any period shorter than a full
quarterly period for which interest is computed, will be computed on the basis
of the actual number of days elapsed in such a 30-day month. In the event that
any date on which interest is payable on the Securities is not a Business Day,
then payment of interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), with the same force and effect as if made
on such date.

     If at any time (including upon the occurrence of a Tax Event) while the
Property Trustee is the Holder of all the Securities, 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 case, the Company will pay
as additional amounts ("Additional Sums") on the Securities 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 governmental charges been imposed.

     The principal of and interest on the Securities shall be payable at the
office or agency of the Company in New York, New York maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at any time that the Property Trustee is not the sole holder of
the Securities, payment of interest may, at the option of the Company, be made
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or by wire transfer.

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

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

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

                                      -18-

Section 3.02  Denominations.

     The Securities shall be issuable only in registered form without coupons
and only in denominations of $1,000 and integral multiples thereof.

Section 3.03  Execution, Authentication, Delivery and Dating.

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

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

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

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual or facsimile signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

Section 3.04  Temporary Securities.

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

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

                                      -19-
<PAGE>

temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

Section 3.05  Global Securities.

(a)  Each Global Security issued under this Indenture shall be registered in the
name of the Depositary designated by the Company for such Global Security or a
nominee thereof and delivered to such Depositary or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.

(b)  Notwithstanding any other provision in this Indenture, no Global Security
may be exchanged in whole or in part for Securities registered, and no transfer
of a Global Security in whole or in part may be registered, in the name of any
Person other than the Depositary for such Global Security or a nominee thereof
unless (i) such Depositary advises the Trustee in writing that such Depositary
is no longer willing or able to continue as a Depositary with respect to such
Global Security, and no successor depositary shall have been appointed, or if at
any time the Depositary ceases to be a "clearing agency" registered under the
Exchange Act, at a time when the Depositary is required to be so registered to
act as such depositary, (ii) the Company in its sole discretion determines that
such Global Security shall be so exchangeable or (iii) there shall have occurred
and be continuing an Event of Default.

(c)  If any Global Security is to be exchanged for other Securities or canceled
in whole, it shall be surrendered by or on behalf of the Depositary or its
nominee to the Security Registrar for exchange or cancellation as provided in
this Article III. If any Global Security is to be exchanged for other Securities
or canceled in part, or if another Security is to be exchanged in whole or in
part for a beneficial interest in any Global Security, then either (i) such
Global Security shall be so surrendered for exchange or cancellation as provided
in this Article III or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
canceled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Security Registrar, whereupon
the Trustee shall instruct the Depositary or its authorized representative to
make a corresponding adjustment to its records. Upon any such surrender or
adjustment of a Global Security by the Depositary, accompanied by registration
instructions and, to the extent required by Section 3.06, a Restricted
Securities Certificate, the Trustee shall, subject to Section 3.05(b) and as
otherwise provided in this Article III, authenticate and make available for
delivery any Securities issuable in exchange for such Global Security (or any
portion thereof) in accordance with the instructions of the Depositary. The
Trustee shall not be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be fully protected in relying on, such
instructions.

(d)  The Depositary or its nominee, as registered owner of a Global Security,
shall be the Holder of such Global Security for all purposes under this
Indenture and the Securities, and owners of beneficial interests in a Global
Security shall hold such interest pursuant to the rules and procedures of the
Depositary. Accordingly, any such owner's beneficial interests in a Global
Security shall be shown only on, and the transfer of such interest shall be
effected only through, records

                                      -20-
<PAGE>

maintained by the Depositary or its nominee or its Agent Members. Neither the
Trustee nor the Security Registrar shall have any liability in respect of any
transfers effected by the Depositary.

(e)  The rights of the beneficial interests in a Global Security shall be
exercised only through the Depositary and shall be limited to those established
by law and agreements between such owners and the Depositary and/or its Agent
Members.

Section 3.06  Registration, Transfer and Exchange Generally; Certain Transfers
              and Exchanges.

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

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

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

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

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.04, 3.05, 9.06, 11.09 or 13.01 not involving any
transfer.

     Neither the Company nor the Trustee shall be required (i) in the case of a
partial redemption of the Securities, to issue, register the transfer of or
exchange any Security during a period beginning

                                      -21-
<PAGE>

at the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities selected for redemption under Section 11.04 and ending
at the close of business on the day of such mailing or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

(b)  Transfer and Exchange Procedures and Restrictions. The Securities may not
be transferred except in compliance with the Restricted Securities Legend unless
otherwise determined by the Company in accordance with applicable law. Upon any
distribution of the Securities to the holders of the Trust Securities in
accordance with the Declaration, the Company and the Trustee shall enter into a
supplemental indenture pursuant to Section 9.01(6) to provide for transfer
procedures and restrictions with respect to the Securities substantially similar
to those contained in the Declaration to the extent applicable in the
circumstances existing at the time of such distribution. Notwithstanding any
other provision of the Indenture, transfers and exchanges of Securities and
beneficial interests in a Global Security of the kinds specified in this Section
3.06(b) shall be made only in accordance with this Section 3.06(b).

(1)  Non-Global Security to Global Security. If the Holder of a Security (other
than a Global Security) wishes at any time to transfer all or any portion of
such Security to a Person who wishes to take delivery thereof in the form of a
beneficial interest in a Global Security, such transfer may be effected only in
accordance with the provisions of this clause (b)(1) and subject to the rules
and procedures of the Depositary. Upon receipt by the Security Registrar of (A)
such Security as provided in Section 3.06(a) and instructions satisfactory to
the Security Registrar directing that a beneficial interest in the Global
Security in a specified principal amount not greater than the principal amount
of such Security be credited to a specified Agent Member's account and (B) a
Securities Certificate duly executed by such Holder or such Holder's attorney
duly authorized in writing, then the Security Registrar shall cancel such
Security (and issue a new Security in respect of the untransferred portion
thereof) as provided in Section 3.06(a) and increase the aggregate principal
amount of the Global Security by the specified principal amount as provided in
Section 3.05(c).

(2)  Non-Global Security to Non-Global Security. A Security that is not a Global
Security may be transferred, in whole or in part, to a Person who takes delivery
in the form of another Security that is not a Global Security as provided in
Section 3.06(a); provided, that if such Security to be transferred in whole or
in part is a Restricted Security, the Security Registrar shall have received the
assignment form attached to the Security duly executed by the transferor Holder
or such Holder's attorney duly authorized in writing.

(3)  Exchanges between Global Security and Non-Global Security.  A beneficial
interest in a Global Security may be exchanged for a Security that is not a
Global Security as provided in Section 3.05.

(c)  Restricted Securities Legend.

(1)  Except as set forth below, all Securities shall bear the Restricted
Securities Legend set forth in Section 2.02.

                                      -22-
<PAGE>

(2)  Subject to Section 3.06(d) and to the following clauses of this Section
3.06(c), a Security (other than a Global Security) that does not bear a
Restricted Securities Legend may be issued in exchange for or in lieu of a
Restricted Security or any portion thereof that bears such legend if, in the
Company's judgment, placing such a legend upon such new Security is not
necessary to ensure compliance with the registration requirements of the
Securities Act, and the Trustee, at the written direction of the Company in the
form of an Officers' Certificate, shall countersign and deliver such a new
Security.

(3)  Notwithstanding the foregoing provisions of this Section 3.06(c), a
successor Security of a Security that does not bear a Restricted Securities
Legend shall not bear such form of legend unless the Company has reasonable
cause to believe that such successor Security is a "restricted security" within
the meaning of Rule 144 under the Securities Act, in which case the Trustee, at
the written direction of the Company in the form of an Officers' Certificate,
shall countersign and deliver a new Security bearing a Restricted Securities
Legend in exchange for such successor Security.

(4)  Upon any sale or transfer of a Restricted Security (including any
Restricted Security represented by a Global Security) pursuant to an effective
registration statement under the Securities Act or pursuant to Rule 144 under
the Securities Act after such registration ceases to be effective: (A) in the
case of any Restricted Security that is a definitive Security, the Security
Registrar shall permit the Holder thereof to exchange such Restricted Security
for a definitive Security that does not bear the Restricted Securities Legend
and shall rescind any restriction on the transfer of such Restricted Security;
and (B) in the case of any Restricted Security that is represented by a Global
Security, the Security Registrar shall permit the Holder of such Global Security
to exchange such Global Security for another Global Security that does not bear
the Restricted Securities Legend.

(5)  If Restricted Securities are being presented or surrendered for transfer or
exchange then there shall be (if so required by the Trustee), (A) if such
Restricted Securities are being delivered to the Security Registrar by a Holder
for registration in the name of such Holder, without transfer, a certification
from such Holder to that effect; or (B) if such Restricted Securities are being
transferred, a certification from the transferor as to the compliance with the
restrictions set forth in the Restricted Securities Legend.

Section 3.07  Mutilated, Destroyed, Lost and Stolen Securities.

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

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed,

                                      -23-
<PAGE>

lost or stolen Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

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

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

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

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

Section 3.08  Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date.

     Any interest on any Security which is payable, but is not punctually paid
or duly provided for, on any Interest 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 (1) or (2) below:

(1)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date (as
defined below) for the payment of such Defaulted Interest, which shall be fixed
in the following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment (which date shall be sufficiently in advance of such
notice to permit the Trustee to timely take the actions contemplated by this
Section 3.08), and at the same time the Company shall deposit with the Trustee
an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to the date of the proposed payment, such money
when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this clause

                                      -24-
<PAGE>

provided. Thereupon the Trustee shall fix a special record date (the "Special
Record Date") for the payment of such Defaulted Interest which shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment
and not less than 10 days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special
Record Date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record
Date therefor to be mailed, first-class postage prepaid, to each Holder at his
address as it appears in the Security Register, not less than 10 days prior to
such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such
Defaulted Interest shall be paid to the Persons in whose names the Securities
(or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to
the following clause (2).

(2)  The Company may make payment of any Defaulted Interest in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities may be listed, and, if so listed, upon such notice as may
be required by such exchange (or by the   Trustee if the Securities are not
listed), if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee provided that any such payment will be made in coin
or currency of the United States of America which at the time of payment is a
legal tender for payment of public and private debt.

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

     In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security that is converted prior to any Regular Record Date, interest
whose Stated Maturity is after the date of conversion of such Security shall not
be payable, and the Company shall not make nor be required to make any other
payment, adjustment or allowance with respect to accrued but unpaid interest
(including Additional Payments) on the Securities being converted, which shall
be deemed to be paid in full.

Section 3.09  Persons Deemed Owners.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 3.08) interest on such Security and for all other

                                      -25-
<PAGE>

purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. No holder of any beneficial interest in any
Global Security held on its behalf by a Depositary shall have any rights under
this Indenture with respect to such Global Security, and such Depositary may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company or the
Trustee from giving effect to any written certification, proxy, or other
authorization furnished by a Depositary or impair, as between the Depositary and
such holders of beneficial interests, the operation of customary practices
governing the exercise of the rights of the Depositary (or its nominee) as
Holder of any Security.

Section 3.10  Cancellation.

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

Section 3.11  Right of Set Off.

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

Section 3.12  CUSIP Numbers.

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

Section 3.13  Extension of Interest Payment Period; Notice of Extension.

(a)  So long as no Event of Default has occurred and is continuing, the Company
shall have the right, at any time during the term of this Security, from time to
time to defer payments of interest by extending for successive periods not
exceeding 20 consecutive quarters for each such period (a "Deferral Period");
provided that no Deferral Period may extend beyond December 15,

                                      -26-
<PAGE>

2029. To the extent permitted by applicable law, interest, the payment of which
has been deferred because of the extension of the interest payment period
pursuant to this Section 3.13, will bear interest thereon at the Applicable Rate
compounded quarterly for each quarter of the Deferral Period ("Compounded
Interest"). On the applicable Payment Resumption Date, the Company shall pay all
interest then accrued and unpaid on the Securities, including any Compounded
Interest that shall be payable to the Holders of the Securities in whose names
the Securities are registered in the Security Register on the Regular Record
Date fixed for such Payment Resumption Date. A Deferral Period shall terminate
upon the payment by the Company of all interest then accrued and unpaid on the
Securities (together with interest thereon accrued at an annual rate equal to
the Applicable Rate, compounded quarterly, to the extent permitted by applicable
law). Before the termination of any Deferral Period, the Company may further
extend such period as provided in paragraph (b) of this Section 3.13, provided
that such period together with all such further extensions thereof shall not
exceed 20 consecutive quarters or extend beyond the Stated Maturity of the
Securities. Upon the termination of any Deferral Period, and subject to the
foregoing requirements, the Company may elect to begin a new Deferral Period. No
interest shall be due and payable during a Deferral Period except on the Payment
Resumption Date as determined pursuant to paragraph (b) of this Section 3.13.
There is no limitation on the number of times that the Company may elect to
begin a Deferral Period.

(b)  The Company shall give the Holder of the Security and the Trustee written
notice (a "Deferral Notice") of its selection of a Deferral Period at least ten
days prior to the record date for any distributions that would have been payable
on the Trust Securities except for the decision to begin or extend a Deferral
Period.  On or prior to the Regular Record Date immediately preceding the
Interest Payment Date on which the Company elects to pay all interest then
accrued and unpaid on the Securities, including Compound Interest (the "Payment
Resumption Date"), the Company shall give the Holder of the Security and the
Trustee written notice that the Deferral Period will end on such Payment
Resumption Date. Notwithstanding the provision of such notice, the Company may
elect to further extend the Deferral Period, subject to the limitations set
forth in Section 3.13(a), by providing the Holder of the Security and the
Trustee with a new Deferral Notice not less than three Business Days prior to
the Regular Record Date immediately preceding the previously scheduled Payment
Resumption Date. The Company may elect to pay all interest then accrued and
unpaid on the Securities, including Compound Interest, on an Interest Payment
Date prior to its most recently established Payment Resumption Date provided
that the Company gives the Holder of the Security and the Trustee a new Deferral
Notice setting forth the revised Payment Resumption Date at least three Business
Days prior to the Regular Record Date for such revised Payment Resumption Date.

(c)  The quarter in which any Deferral Notice is given pursuant to paragraph (b)
hereof shall be counted as one of the 20 quarters permitted in the maximum
Deferral Period permitted under paragraph (a) hereof.

Section 3.14 Paying Agent, Security Registrar and Conversion Agent.

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

Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and interest for
whose payment such money has been deposited with the Trustee. All moneys
deposited with the Trustee pursuant to Section 4.01 (and held by it or any
Paying Agent) for the payment of Securities subsequently converted shall be
returned to the Company upon Company Request.

by the Trustee or to the Company and the Trustee by the Holders of at least 25%
in aggregate outstanding principal amount of the Securities a written notice
specifying such default and requiring it to be remedied; or

(4)  failure by the Company to issue and deliver Common Stock upon an election

(5)  the entry or a decree or order by a court having jurisdiction in the

Section 5.02  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities may declare the principal of all the Outstanding
Securities and any other amounts payable hereunder (including any Additional
Payments) to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders); provided that, if the Property
Trustee is the sole Holder of the Securities and if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities fail to declare the principal of all the Securities to be
immediately due and payable, the holders of at least 25% in aggregate
liquidation amount of Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee; and upon any such
declaration such principal and all accrued interest shall become immediately due
and payable. Upon any such declaration such principal amount (or specified
amount) of and the accrued interest (including any Additional Payments) on all
the Securities shall then become immediately due and payable; provided that the
payment of principal and interest on such Securities (including Additional
Payments) shall remain subordinated to the extent provided in Article XII.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as provided in this Article

                                      -30-
<PAGE>

hereinafter, the Holders of a majority in aggregate principal amount of the
Outstanding Securities or of a majority in liquidation amount of Preferred
Securities, as the case may be, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

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

(A)  all overdue interest (including any Compounded Interest) on all Securities,

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

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

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

     The Company is required to file annually with the Trustee a certificate as
to whether or not the Company is in compliance with all the conditions and
covenants applicable to it under this Indenture.

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

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee.
             The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest (including any Additional Payments) and,
to the extent that payment thereof shall be legally enforceable, interest on any
overdue principal and on any overdue interest (including any Additional

                                      -31-
<PAGE>

Sums), at the rate borne by the Securities, and, in addition thereto,
all amounts owing to the Trustee under Section 6.07.

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

Section 5.04  Trustee May File Proofs of Claim.

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

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

Section 5.05  Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of all the amounts owing to the Trustee and any predecessor
Trustee under Section 6.07, be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

Section 5.06  Application of Money Collected.

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

                                      -32-
<PAGE>

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

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

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

Section 5.07 Limitation on Suits.

     Subject to Section 5.08, no Holder of any Security shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

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

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

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

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

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

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

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

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and (subject

                                      -33-
<PAGE>

to Section 3.08) interest (including any Additional Payments) on such Security
on the respective Stated Maturities expressed in such Security (or, in the case
of redemption, on the Redemption Date) and to convert such Security in
accordance with Article XIII and to institute suit for the enforcement of any
such payment and right to convert, and such rights shall not be impaired without
the consent of such Holder. If the Property Trustee is the sole Holder of the
Securities, any holder of the Preferred Securities shall have the right to
institute suit on behalf of the Trust for the enforcement of any such payment
and right to convert.

Section 5.09  Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

Section 5.10  Rights and Remedies Cumulative.

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

Section 5.11  Delay or Omission Not Waiver.

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

Section 5.12  Control by Holders.

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

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

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

                                      -34-
<PAGE>

(3)  subject to Section 6.01, the Trustee need not take any action that might
involve the Trustee in personal liability or be unduly prejudicial to the
Holders not joining therein.

Section 5.13  Waiver of Past Defaults.

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

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

(2)  in respect of a covenant or provision hereof which under Article IX cannot
be modified or amended without the consent of the Holder of each Outstanding
Security affected.

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

Section 5.14  Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or the Trustee or in
any suit for the enforcement of the right to receive the principal of and
interest (including any Additional Payments) on any Security or to convert any
Security in accordance with Article XIII.

Section 5.15  Waiver of Stay or Extension Laws.

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

Section 5.16  Enforcement by Holders of Preferred Securities.

     Notwithstanding anything to the contrary contained herein, if an Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on the Securities on the
date such interest or principal is otherwise payable, the Company acknowledges
that, in such event, a holder of Preferred Securities may institute a legal
proceeding directly for enforcement of payment to such Holder of the principal
of or interest on the Debentures having a principal amount equal to the
aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct Action") on or after the respective due date specified in the
Securities. The Company may not amend this Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of all the
holders of Preferred Securities. Notwithstanding any payment made to such holder
of Preferred Securities by the Company in connection with a Direct Action, the
Company shall remain obligated to pay the principal of and interest on the
Securities (including Additional Payments, if any) held by the Trust or the
Property Trustee and the Company shall be subrogated to the rights of the holder
of such Preferred Securities with respect to payments on the Preferred
Securities to the extent of any payments made by the Company to such holder in
any Direct Action. The holders of Preferred Securities will not be able to
exercise directly any other remedy available to the Holders of the Securities.

                                  THE TRUSTEE

Section 6.01  Certain Duties and Responsibilities.

(a)  Except during the continuance of an Event of Default, the Trustee
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture, and no implied covenants or obligations shall be read
into this Indenture against the Trustee.

(b)  In case an Event of Default has occurred and is continuing, and is known to
the Trustee, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, 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 own affairs.

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

Section 6.02  Notice of Defaults.

     The Trustee shall give the Holders notice of any default hereunder known to
the Trustee as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
5.01(3), no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default.

Section 6.03  Certain Rights of Trustee.

     Subject to the provisions of Section 6.01:

(a)  the Trustee may conclusively 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, other evidence of indebtedness or other paper or document 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 Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

forthwith upon its acceptance of such appointment, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona

resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
provided, that on request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder. Upon

least 25% in principal amount of the Securities then outstanding, the Company
shall for such purpose join with the Trustee in the execution and delivery of
all instruments and agreements necessary or proper to appoint one or more
Persons approved by the Trustee either to act as co-trustee, jointly with the
Trustee, or to act as separate trustee, in either case with such powers as may
be provided in the instrument of appointment, and to vest in such Person or
Persons in the capacity aforesaid, any property, title, right or power deemed
necessary or desirable, subject to the other provisions of this Section.  If the

Company.

     Every co-trustee or separate trustee shall, to the extent permitted by law,

provided in the instrument appointing such co-trustee or separate trustee,
except to the extent that under any law of any jurisdiction in which any
particular act is to be performed, the Trustee shall be incompetent or
unqualified to perform such act, in which event such rights, powers, duties and
obligations shall be exercised and performed by such co-trustee or separate
trustee;

(c)  the Trustee at any time, by an instrument in writing executed by it, with
the concurrence of the Company, may accept the resignation of or remove any co-
trustee or separate trustee appointed under this Section, and, if an Event of
Default shall have occurred and be continuing, the Trustee shall have power to
accept the resignation of, or remove, any such co-trustee or separate trustee
without the concurrence of the Company.  Upon the written request of the
Trustee, the Company shall join with the Trustee in the execution and delivery
of all instruments and agreements, necessary or proper to effectuate such
resignation or removal.  A successor to any co-trustee or separate trustee so

notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain 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
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     The Company may also from time to time designate one or more other offices
or agencies (in the United States) where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in the United States for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

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

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

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

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

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

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

Section 10.04  Statement by Officers as to Default.

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

the shares of Common Stock of the Company issuable upon conversion of the
Securities (collectively, the "Registrable Securities") are entitled to the
benefits of a Registration Rights Agreement, dated as of December 15, 1999,

Rights Agreement"). Pursuant to the Registration Rights Agreement the Company
and the Trust have agreed for the benefit of the holders of the Registrable

rule or regulation thereto or such earlier date as is provided in the
Registration Rights Agreement. If the Company fails to comply with either of
clauses (ii) or (iii) above, subject to certain exceptions provided in the
Registration Rights Agreement, (a "Registration Default") then, at such time,
the Applicable Rate will increase by 50 basis points (.50%). Such increase will
remain in effect from and including the date on which any such Registration
Default shall occur to but excluding the date on which all Registration Defaults
have been cured, on which date the interest rate on the Securities will revert
to the interest rate originally borne by the Securities.

Section 10.08  Offering Document Amendment or Supplement.

     The Trust and the Company will advise each Initial Purchaser promptly of
any proposal to amend or supplement the final confidential offering circular
dated December 9, 1999 (the "Offering Document"), and will not effect such
amendment or supplementation without the Initial Purchasers' consent.  If, at
any time, any event occurs as a result of which the Offering Document as then
amended or supplemented would include an untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary at any such time to amend or supplement the
Offering Document to comply with any applicable law, the Trust and the Company
promptly will notify each Initial Purchaser of such event and promptly will
prepare, at their own expense, an amendment or supplement which will correct
such statement or omission or effect such compliance.  Neither the Initial
Purchasers' consent to nor the Initial Purchasers' delivery to offerees or
investors of, any such amendment or supplement shall constitute a waiver of any
of the conditions set forth in Section 6 of the Purchase Agreement.

                           REDEMPTION OF SECURITIES

Section 11.01  Optional Redemption.

     The Company shall have the right to redeem the Securities (an "Optional
Redemption") in whole or in part, at any time or from time to time on or after
December 20, 2002, at a Redemption Price (the "Optional Redemption Price") equal
to the prices per $50 principal amount of Securities set forth in the following
table, plus accrued and unpaid interest, including Additional Payments, if any,
to the Redemption Date, if redeemed during the 12-month period ending on

<TABLE>
<CAPTION>
                             Price Per $50

2006                             $50.00
</TABLE>

and thereafter at $50 per $50 principal amount of the Securities plus, in each
case, any accrued and unpaid interest, including Additional Payments, if any, to
the Redemption Date.

11.02  Tax Event Redemption.

     If a Tax Event has occurred and is continuing and:

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

                                      -52-
<PAGE>

(2)  the Issuer Trustees shall have been informed by nationally recognized
independent tax counsel (reasonably acceptable to the Issuer Trustees)
experienced in such matters that a No Recognition Opinion cannot be delivered,

then the Company shall have the right upon not less than 20 days, nor more than
60 days, notice to the Holders of the Securities to redeem the Securities in
whole, but not in part, for cash at $50 per $50 principal amount of the
Securities plus accrued and unpaid interest, including Additional Payments, if
any, to the Redemption Date, within 90 days following the occurrence of such Tax
Event (the "90 Day Period"); provided, however, that if, at the time there is
available to the Company or the Trust the opportunity to eliminate, within the
90 Day Period, the Tax Event by taking some ministerial action, including, but
not limited to, filing a form or making an election, or pursuing some other
similar reasonable measure which, in the sole judgment of the Company, will have
no adverse effect on the Company, the Trust or the Holders of the Preferred
Securities and will involve no material cost, then the Company or the Trust
shall pursue such ministerial action or other measure in lieu of redemption; and
provided further that the Company shall have no right to redeem the Securities
while the Trust is pursuing any ministerial action or other similar measure
pursuant to its obligations under the Declaration.

     If the Company opts not to redeem the Securities pursuant to this Section
11.02, the Company shall be required to pay Additional Sums in respect of the
Securities pursuant to Section 3.01 for so long as (i) a Tax Event has occurred
and is continuing and (ii) the Property Trustee is the sole Holder of the
Securities.

Section 11.03  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee by
such method as the Trustee shall deem fair and appropriate, from the Outstanding
Securities not previously called for redemption. Such selection method may
provide for the selection for redemption of portions (equal to $50 or any
integral multiple thereof) of the principal amount of the Securities.

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

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

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

Section 11.04  Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 20 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at such Holder's address appearing in
the Security Register.

     All notices of redemption given pursuant to this Article XI shall identify
the Securities to be redeemed (including, if relevant, CUSIP number) and shall
state:

(1)  the Redemption Date,

(2)  the Redemption Price,

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

(4)  the place or places where such Securities are to be surrendered for payment
of the Redemption Price, and

(5)  the date on which the right to convert the Securities to be redeemed will
terminate and the places where such Securities may be surrendered for
conversion.

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

Section 11.05  Deposit of Redemption Price.

     Prior to 12:00 noon on any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 10.03) an
amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

     If any Security called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any Predecessor Security to receive interest as provided in the
last paragraph of Section 3.08) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

Section 11.06  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price

                                      -54-
<PAGE>

and accrued interest) such Securities shall cease to bear interest. Upon
surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company at the Redemption Price; provided,
however, that installments of interest whose Stated Maturity is on or prior to
the Redemption Date shall be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to the terms and the provisions of Section
3.08.

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

Section 11.07  Securities Redeemed in Part.

(a)  In the event of any redemption in part, the Company shall not be required
(i) to issue, register the transfer of or exchange any Security during a period
beginning at the opening of business 15 days before the date of the mailing of a
notice of redemption of Securities selected for redemption and ending at the
close of business on the day of such mailing and (ii) to register the transfer
of or exchange any Securities so selected for redemption, in whole or in part,
except for the unredeemed portion of any Securities being redeemed in part.

(b)  If a partial redemption of the Securities would result in the delisting of
the Preferred Securities issued by the Trust from any national securities
exchange or other organization on which the Preferred Securities are listed, the
Company shall not be permitted to effect such partial redemption and may only
redeem the Securities in whole.

(c)  Any Security which is to be redeemed only in part shall be surrendered at a
place of payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and make available for delivery to the Holder of such
Security without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered. If a Global Security is surrendered, such new Security will
(subject to Section 3.06) also be a new Global Security.

                          SUBORDINATION OF SECURITIES

Section 12.01  Agreement to Subordinate.

     The Company covenants and agrees, and each Holder of Securities by such
Holder's acceptance thereof likewise covenants and agrees, that all Securities
shall be issued subject to the provisions of this Article XII; and each Holder
of a Security, whether upon original issue or upon transfer or assignment
thereof, accepts and agrees to be bound by such provisions. The payment by the
Company of the principal of, premium, if any, and interest (including Additional
Payments) on

                                      -55-
<PAGE>

all Securities issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all Senior Debt, whether outstanding at the date of
this Indenture or thereafter incurred; provided, however, that no provision of
this Article XII shall prevent the occurrence of any default or Event of Default
hereunder.

Section 12.02  Default on Senior Debt.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Debt continuing beyond the period of grace, if any, specified in the
instrument evidencing such Senior Debt, unless and until such default shall have
been cured or waived or shall have ceased to exist, and in the event that the
maturity of any Senior Debt has been accelerated because of a default, then no
payment shall be made by the Company with respect to the principal of (including
redemption payments), premium, if any, or interest on the Securities.

     In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 12.02, subject to Section 12.06, such payment shall be
held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Senior Debt or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Debt may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Debt (or their representative or representatives
or a trustee) notify the Trustee in writing within 90 days of such payment of
the amounts then due and owing on the Senior Debt and only the amounts specified
in such notice to the Trustee shall be paid to the holders of Senior Debt.

Section 12.03  Liquidation; Dissolution; Bankruptcy.

     Upon any payment by the Company or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding up or liquidation or reorganization of the
Company, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts (including principal, premium, if
any, and interest) due or to become due upon all Senior Debt (including any
interest accruing subsequent to the filing of a petition for bankruptcy
regardless of whether such interest is an allowed claim in the bankruptcy
proceeding) shall first be paid in full in cash, or payment thereof provided for
in money in accordance with and to the extent permitted by the terms of such
Senior Debt, before any payment is made on account of the principal (and
premium, if any) or interest on the Securities; and upon any such dissolution or
winding up or liquidation or reorganization, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holders of the Securities or the Trustee
would be entitled, except for the provisions of this Article XII, shall be paid
by the Company or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the Holders of
the Securities or by the Trustee under this Indenture if received by them or it,
directly to the holders of Senior Debt (pro rata to such holders on the basis of
the respective amounts of Senior Debt held by such holders, as calculated by the
Company) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Debt may have been issued, as their respective interests may appear, to
the extent necessary to pay

                                      -56-
<PAGE>

such Senior Debt in full, in cash or in money's worth in accordance with and to
the extent permitted by the terms of such Senior Debt, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Debt, before any payment or distribution is made to the Holders of Securities or
to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing shall be received by the
Trustee or the Holders of the Securities before all Senior Debt is paid in full
in cash, or provision is made for such payment in money in accordance and to the
extent permitted by the terms of such Senior Debt subject to Section 12.06, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of Senior Debt or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Debt may have been issued, and
their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Debt remaining unpaid to the extent
necessary to pay such Senior Debt in full in cash or in money's worth in
accordance with and to the extent permitted by the terms of such Senior Debt,
after giving effect to any concurrent payment or distribution to or for the
holders of such Senior Debt.

     For purposes of this Article XII, the words, "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article XII with respect to
the Securities to the payment of all Senior Debt which may at the time be
outstanding; provided that (i) such Senior Debt is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment, and
(ii) the rights of the holders of such Senior Debt are not, without the consent
of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company with or into,
another Person or the liquidation or dissolution of the Company following the
conveyance, transfer or lease of all or substantially all its properties and
assets on a consolidated basis to another Person upon the terms and conditions
provided for in Article VIII hereof shall not be deemed a dissolution, winding
up, liquidation or reorganization for the purposes of this Section 12.03 if such
other Person shall, as a part of such consolidation, merger, conveyance,
transfer or lease, comply with the conditions stated in Article VIII hereof.
Nothing in Section 12.02 or in this Section 12.03 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.07 hereof.

Section 12.04  Subrogation.

     Subject to the prior payment in full of all Senior Debt in cash or in
money's worth in accordance with and to the extent permitted by the terms of
such Senior Debt, the rights of the Holders of the Securities shall be
subrogated to the rights of the holders of such Senior Debt to receive payments
or distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Debt until the principal of (and premium, if any)
and interest on the Securities shall be paid in full; and, for the purposes of
such subrogation, no payments or distributions to the holders of such Senior
Debt of any cash, property or securities to which the Holders of the Securities
or the Trustee would be entitled except for the provisions of this Article XII,
and no payment pursuant to the provisions of this Article XII, to or for the
benefit of the holders

                                      -57-

of such Senior Debt by Holders of the Securities or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Debt, and the
Holders of the Securities, be deemed to be a payment by the Company to or on
account of such Senior Debt. It is understood that the provisions of this
Article XII are and are intended solely for the purposes of defining the
relative rights of the Holders of the Securities, on the one hand, and the
holders of such Senior Debt on the other hand.

     Nothing contained in this Article XII or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Debt, and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of (and premium, if any)
and interest on the Securities as and when the same shall become due and payable
in accordance with their terms, or is intended to or shall affect the relative
rights of the Holders of the Securities and creditors of the Company, as the
case may be, other than the holders of Senior Debt, nor shall anything herein or
therein prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article XII of the holders
of such Senior Debt in respect of cash, property or securities of the Company,
as the case may be, received upon the exercise of any such remedy.

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

Section 12.05  Trustee to Effectuate Subordination.

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

Section 12.06  Notice by the Company.

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

                                      -58-
<PAGE>

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

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

Section 12.07  Rights of the Trustee; Holders of Senior Debt.

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

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

Section 12.08  Subordination May Not Be Impaired.

     No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any

                                      -59-
<PAGE>

noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the holders of the Securities and without impairing
or releasing the subordination provided in this Article XII or the obligations
hereunder of the Holders of the Securities to the holders of Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, such Senior Debt, or
otherwise amend or supplement in any manner such Senior Debt or any instrument
evidencing the same or any agreement under which such Senior Debt is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing such Senior Debt; (iii) release any
Person liable in any manner for the collection of such Senior Debt; and (iv)
exercise or refrain from exercising any rights against the Company and any other
Person.

                                 ARTICLE XIII

                           CONVERSION OF SECURITIES

Section 13.01  Conversion Rights.

     Subject to and upon compliance with the provisions of this Article, the
Securities are convertible, at the option of the Holder, at any time prior to
5:00 p.m. New York City time on the Business Day immediately preceding December
15, 2029 into fully paid and nonassessable shares of Common Stock at an initial
conversion rate of 1.3986 shares of Common Stock for each $50 in aggregate
principal amount of Securities (the "Initial Conversion Ratio") (equal to a
conversion price of $35.75 principal amount of Securities per share of Common
Stock (the "Initial Conversion Price")). The conversion ratio and the equivalent
conversion price in effect at any given time are known as the "Applicable
Conversion Ratio" and the "Applicable Conversion Price", respectively, and are
subject to adjustment as described in this Article XIII. A Holder of Securities
may convert any portion of the principal amount of the Securities into that
number of fully paid and nonassessable shares of Common Stock (calculated as to
each conversion to the nearest 1/100th of a share) obtained by dividing the
principal amount of the Securities to be converted by the Applicable Conversion
Ratio. In case a Security or portion thereof is called for redemption, such
conversion right in respect of the Security or portion so called shall expire at
the close of the Business Day immediately preceding the corresponding Redemption
Date, unless the Company defaults in making the payment due upon redemption.

Section 13.02  Conversion Procedures.

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

                                      -60-
<PAGE>

its right under the Declaration to convert such Preferred Securities into Common
Stock by delivering to the Conversion Agent an irrevocable Notice of Conversion
setting forth the information called for by the preceding sentence and directing
the Conversion Agent (i) to exchange such Preferred Security for a portion of
the Securities held by the Trust (at an exchange rate of $50 principal amount of
Securities for each Preferred Security) and (ii) to immediately convert such
Securities, on behalf of such holder, into Common Stock of the Company pursuant
to this Article XIII and, if such Preferred Securities are in definitive form,
surrendering such Preferred Securities, duly endorsed or assigned to the Company
or in blank. So long as any Preferred Securities are outstanding, the Trust
shall not convert any Securities except pursuant to a Notice of Conversion duly
executed and delivered to the Conversion Agent by a holder of Preferred
Securities.

     If a Notice of Conversion is delivered on or after the Regular Record Date
and prior to the subsequent Interest Payment Date, the Holder will be entitled
to receive the interest payable on the subsequent Interest Payment Date on the
portion of Securities to be converted notwithstanding the conversion thereof
prior to such Interest Payment Date. Except as otherwise provided in the
immediately preceding sentence, in the case of any Security which is converted,
interest whose Stated Maturity is after the date of conversion of such Security
shall not be payable, and the Company shall not make nor be required to make any
other payment, adjustment or allowance with respect to accrued but unpaid
interest on the Securities being converted, which shall be deemed to be paid in
full. Each conversion shall be deemed to have been effected immediately prior to
the close of business on the day on which the Notice of Conversion was received
(the "Conversion Date") by the Conversion Agent from the Holder or from a holder
of the Preferred Securities effecting a conversion thereof pursuant to its
conversion rights under the Declaration, as the case may be. The Person or
Persons entitled to receive the Common Stock issuable upon such conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
as of the Conversion Date. As promptly as practicable on or after the Conversion
Date, the Company shall issue and deliver at the office of the Conversion Agent,
unless otherwise directed by the Holder in the Notice of Conversion, a
certificate or certificates for the number of full shares of Common Stock
issuable upon such conversion, together with the cash payment, if any, in lieu
of any fraction of any share to the Person or Persons entitled to receive the
same. The Conversion Agent shall deliver such certificate or certificates to
such Person or Persons.

(b)  Subject to any right of the Holder of such Security or any Predecessor
Security to receive interest as provided in the last paragraph of Section 3.08
and the second paragraph of clause (a) of Section 13.02, the Company's delivery
upon conversion of the whole number of shares of Common Stock into which the
Securities are convertible (together with the cash payment, if any, in lieu of
fractional shares) shall be deemed to satisfy the Company's obligation to pay
the principal amount at Maturity of the portion of Securities so converted and
any unpaid interest (including Compounded Interest and Additional Sums) accrued
on such Securities at the time of such conversion.

(c)  No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, the Company shall pay to the Conversion Agent a
cash adjustment in an amount equal to the same fraction of the Closing Price of
such fractional interest on the date on which the Securities or Preferred
Securities, as the case may be, were duly surrendered to the Conversion Agent
for conversion, or, if such day is not a Trading Day, on the next Trading Day,
and

                                      -61-
<PAGE>

the Conversion Agent in turn will make such payment, if any, to the Holder of
the Securities or the holder of the Preferred Securities so converted.

(d)  In the event of the conversion of any Security in part only, a new Security
or Securities for the unconverted portion thereof will be issued in the name of
the Holder thereof upon the cancellation thereof in accordance with Section
3.06.

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

(f)  All shares of Common Stock delivered upon any conversion of Restricted
Securities shall bear a restrictive legend substantially in the form of the
legend required to be set forth on such Securities and shall be subject to the
restrictions on transfer provided in such legend and in Section 3.06(b) hereof.
Neither the Trustee nor the Conversion Agent shall have any responsibility for
the inclusion or content of any such restrictive legend on such Common Stock;
provided, however, that the Trustee or the Conversion Agent shall have provided
to the Company or to the Company's transfer agent for such Common Stock, prior
to or concurrently with a request to the Company to deliver to such Conversion
Agent certificates for such Common Stock, written notice that the Securities
delivered for conversion are Restricted Securities.

Section 13.03  Conversion Price Adjustments.

     The Applicable Conversion Price shall be subject to adjustment (without
duplication) from time to time as follows:

(i)  In case the Company shall pay a dividend or make a distribution on the
Common Stock exclusively in Common Stock, the Applicable Conversion Price in
effect at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be reduced by multiplying such Applicable Conversion Price by
a fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
and the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such
reduction

                                      -62-
<PAGE>

to become effective immediately after the opening of business on the day
following the date fixed for such determination. For the purposes of this
subparagraph (i), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company.

     In the event that such dividend or distribution is not so paid or made, the
Applicable Conversion Price shall again be adjusted to be the Applicable
Conversion Price which would then be in effect if such dividend or distribution
had not occurred.

(ii)  In case the Company shall pay or make a dividend or other distribution on
its Common Stock consisting exclusively of, or shall otherwise issue to all
holders of its Common Stock, rights or warrants, in each case entitling the
holders thereof to subscribe for or purchase shares of Common Stock at a price
per share less than the current market price per share (determined as provided
in subparagraph (vii)) of the Common Stock on the date fixed for the
determination of stockholders entitled to receive such rights or warrants, the
Applicable Conversion Price in effect at the opening of business on the day
following the date fixed for such determination shall be reduced by multiplying
such Applicable Conversion Price by a fraction of which the numerator shall be
the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
current market price and the denominator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such reduction to become effective immediately prior
to the opening of business on the day following the date fixed for such
determination. To the extent that rights are not so issued or shares of Common
Stock are not so delivered after the expiration of such rights or warrants, the
Applicable Conversion Price shall be readjusted to the Applicable Conversion
Price which would then be in effect if such date fixed for the determination of
stockholders entitled to receive such rights or warrants had not been fixed. For
the purposes of this subparagraph (ii), the number of shares of Common Stock at
any time outstanding shall not include shares held in the treasury of the
Company.

(iii)  In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Applicable Conversion Price in
effect at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced and, conversely,
in case outstanding shares of Common Stock shall each be combined into a smaller
number of shares of Common Stock, the Applicable Conversion Price in effect at
the opening of business on the day following the day upon which such combination
becomes effective shall be proportionately increased, such reduction or
increase, as the case may be, to become effective immediately prior to the
opening of business on the day following the day upon which such subdivision or
combination becomes effective.

(iv)  Subject to the last sentence of this subparagraph (iv), in case the
Company shall, by dividend or otherwise, distribute to all holders of its Common
Stock

                                      -63-
<PAGE>

evidences of its indebtedness, shares of any class or series of capital stock,
cash or assets (including securities, but excluding any rights or warrants
referred to in subparagraph (ii) of this Section 13.03, any dividend or
distribution paid exclusively in cash and any dividend or distribution referred
to in subparagraph (i) of this Section 13.03), the Applicable Conversion Price
shall be reduced so that the same shall equal the price determined by
multiplying the Applicable Conversion Price in effect immediately prior to the
effectiveness of the Applicable Conversion Price reduction contemplated by this
subparagraph (iv) by a fraction of which the numerator shall be the current
market price per share (determined as provided in subparagraph (vii) of this
Section 13.03) of the Common Stock on the date fixed for the determination of
stockholders entitled to receive such distribution (the "Reference Date") less
the fair market value (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a resolution of the
Board of Directors), on the Reference Date, of the portion of the evidences of
indebtedness, shares of capital stock, cash and assets so distributed applicable
to one share of Common Stock and the denominator shall be such current market
price per share of the Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the Reference
Date. In the event that such dividend or distribution is not so paid or made,
the Applicable Conversion Price shall again be adjusted to be the Applicable
Conversion Price which would then be in effect if such dividend or distribution
had not occurred. For purposes of this subparagraph (iv), any dividend or
distribution that includes shares of Common Stock or rights or warrants to
subscribe for or purchase shares of Common Stock shall be deemed instead to be
(1) a dividend or distribution of the evidences of indebtedness, shares of
capital stock, cash or assets other than such shares of Common Stock or such
rights or warrants (making any Applicable Conversion Price reduction required by
this subparagraph (iv)) immediately followed by (2) a dividend or distribution
of such shares of Common Stock or such rights or warrants (making any further
Applicable Conversion Price reduction required by subparagraph (i) or (ii) of
this Section 13.03), except any shares of Common Stock included in such dividend
or distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of subparagraph (i) of
this Section 13.03.

(v)  In case the Company shall pay or make a dividend or other distribution on
its Common Stock exclusively in cash (excluding (x) cash dividends to the extent
that they do not exceed the per share amount of the smallest of the immediately
four preceding quarterly cash dividends (as adjusted to appropriately reflect
any of the events referred to in subparagraphs (i), (ii), (iii), (iv), (v) and
(vi)), and (y) cash dividends to the extent that the annualized per share amount
thereof does not exceed 12.5% of the current market price per share of the
Common Stock on the Trading Day next preceding the date of declaration of such
dividend, the Applicable Conversion Price shall be reduced so that the same
shall equal the price determined by multiplying the Applicable Conversion Price
in effect immediately prior to the effectiveness of the Applicable Conversion
Price reduction contemplated by this subparagraph (v) by a fraction of which the
numerator shall be the current market price per share (determined as provided in
subparagraph (vii) of this Section 13.03) of the Common Stock on the date fixed
for the payment of such distribution less the amount of cash so distributed and
not excluded as provided applicable to one share of Common Stock and the
denominator shall be such current market price per share of the Common Stock,
such

                                      -64-
<PAGE>

reduction to become effective immediately prior to the opening of business on
the day following the date fixed for the payment of such distribution; provided,
however, that in the event the portion of the cash so distributed applicable to
one share of Common Stock is equal to or greater than the current market price
per share (as defined in subparagraph (vii) of this Section 13.03) of the Common
Stock on the record date mentioned above, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Holder of Securities shall have
the right to receive upon conversion the amount of cash such Holder would have
received had such Holder converted each Security immediately prior to the record
date for the distribution of the cash. In the event that such dividend or
distribution is not so paid or made, the Applicable Conversion Price shall again
be adjusted to be the Applicable Conversion Price which would then be in effect
if such record date had not been fixed.

(vi)  In case a tender or exchange offer (other than an odd-lot offer) made by
the Company or any Subsidiary of the Company for all or any portion of the
Company's Common Stock shall expire and such tender or exchange offer shall
involve the payment by the Company or such Subsidiary of consideration per share
of Common Stock having a fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors) at the last time (the "Expiration Time")
tenders or exchanges may be made pursuant to such tender or exchange offer (as
it shall have been amended) that exceeds 110% of the current market price per
share (determined as provided in subparagraph (vii) of this Section 13.03) of
the Common Stock on the Trading Day next succeeding the Expiration Time, the
Applicable Conversion Price shall be reduced so that the same shall equal the
price determined by multiplying the Applicable Conversion Price in effect
immediately prior to the effectiveness of the Applicable Conversion Price
reduction   contemplated by this subparagraph (vi) by a fraction of which the
numerator shall be the number of shares of Common Stock outstanding (including
any tendered or exchanged shares) at the Expiration Time multiplied by the
current market price per share (determined as provided in subparagraph (vii) of
this Section 13.03) of the Common Stock on the Trading Day next succeeding the
Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Common Stock outstanding (less any Purchased
Shares) at the Expiration Time and the current market price per share
(determined as provided in subparagraph (vii) of this Section 13.03) of the
Common Stock on the Trading Day next succeeding the Expiration Time, such
reduction to become effective immediately prior to the opening of business on
the day following the Expiration Time.

(vii)  For the purpose of any computation under subparagraphs (ii), (iv), (v)
and (vi) of this Section 13.03, the current market price per share of Common
Stock on any date in question shall be deemed to be the average of the daily
Closing Prices of the Common Stock for the ten consecutive Trading Days prior to
the earlier of the day in question and, if applicable, the day before the "ex"
date with respect to the issuance or distribution requiring such computation;
provided, however, that if another event occurs that would require an

                                      -65-
<PAGE>

adjustment pursuant to subparagraphs (i) through (vi) of this Section 13.03,
inclusive, the Board of Directors may make such adjustments to the Closing
Prices during such five Trading Day period as it deems appropriate to effectuate
the intent of the adjustments in this Section 13.03, in which case any such
determination by the Board of Directors shall be set forth in a Board Resolution
and shall be conclusive. For purposes of this paragraph, the term "ex" date, (1)
when used with respect to any issuance or distribution, means the first date on
which the Common Stock is quoted regular way on the New York Stock Exchange
Composite Tape or on such successor securities exchange on which the Common
Stock may be quoted or listed or in the relevant market from which the Closing
Prices were obtained without the right to receive such issuance or distribution,
and (2) when used with respect to any tender or exchange offer means the first
date on which the Common Stock is quoted regular way on such securities exchange
or in such market after the Expiration Time of such offer.

(viii)  The Company may make such reductions in the Applicable Conversion Price,
in addition to those required by subparagraphs (i), (ii), (iii), (iv), (v) and
(vi) of this Section 13.03, as it considers to be advisable to avoid or diminish
any income tax to holders of Common Stock or rights to purchase Common Stock
resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes.

(ix)  There shall also be no adjustment of the Applicable Conversion Price in
case of the issuance of any Common Stock (or securities convertible into or
exchangeable for Common Stock), except as specifically described above. If any
action would require adjustment of the Applicable Conversion Price, pursuant to
more than one of the anti-dilution provisions set forth in this Article XIII,
only one adjustment shall be made and such adjustment shall be the amount of
adjustment that has the highest absolute value to Holders. Furthermore, no
adjustment in the Applicable Conversion Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
Applicable Conversion Price; provided, however, that any adjustments which by
reason of this sentence are not required to be made shall be carried forward and
taken into account in determining whether any subsequent adjustment shall be
required.

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

     In the event that the Company shall be a party to any transaction
(including without limitation (a) any recapitalization or reclassification of
the Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination of the Common Stock), (b) any consolidation of the Company with, or
merger of the Company into, any other Person, any merger of another Person into
the Company (other than a merger which does not result in a reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of
the Company), (c) any sale or transfer of all or substantially all of the assets
of the Company or (d) any compulsory share exchange) (each of the events in the
preceding clauses (a) through (d) being referred to as a "Company Transaction"),
in each case, as a result of which shares of Common Stock shall be converted
into the right to receive other securities, cash or other property, then lawful
provision shall be made as part of the terms of such Company

                                      -66-
<PAGE>

Transaction whereby the Holder of each Security then outstanding shall have the
right thereafter to convert such Security only into (i) in the case of any
Company Transaction other than a Common Stock Fundamental Change, the kind and
amount of securities, cash and other property receivable upon the consummation
of the Company Transaction by a holder of that number of shares of Common Stock
into which such Security was convertible immediately prior to such transaction,
after giving effect to any adjustment in the Applicable Conversion Price
required by the provisions of Section 13.07(a)(i), and (ii) in the case of a
Company Transaction involving a Common Stock Fundamental Change, common stock of
the kind received by holders of Common Stock as a result of such Common Stock
Fundamental Change in an amount determined pursuant to the provisions of Section
13.07(a)(ii). Holders of the Securities shall have no voting rights with respect
to any Company Transaction described in this Section 13.04.

     The Company or the Person formed by such consolidation or resulting from
such merger or which acquired such assets or which acquires the Company's
shares, as the case may be, shall make provision in its certificate or articles
of incorporation or other constituent document to establish such right. Such
certificate or articles of incorporation or other constituent document shall
provide for adjustments which, for events subsequent to the effective date of
such certificate or articles of incorporation or other constituent document,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article XIII. The above provisions shall similarly apply to
successive transactions of the foregoing type.

Section 13.05  Notice of Adjustments of Conversion Price.

     Whenever the Applicable Conversion Price is adjusted as herein provided:

(a)  the Company shall compute the adjusted Applicable Conversion Price and
shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted Applicable Conversion Price
and showing in reasonable detail the facts upon which such adjustment is based,
and such certificate shall forthwith be filed with the Trustee, the Conversion
Agent, the Property Trustee and the transfer agent for the Preferred Securities
and the Securities; and

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

Section 13.06  Prior Notice of Certain Events.

     In case:

(i)  the Company shall (1) declare any dividend (or any other distribution) on
its Common Stock, other than (A) a dividend payable in shares of Common Stock or
(B) a dividend payable in cash that would not require an adjustment pursuant to
Section 13.03(iv)

                                      -67-
<PAGE>

or (v) or (2) authorize a tender or exchange offer that would
require an adjustment pursuant to Section 13.03(vi);

(ii)  the Company shall authorize the granting to all holders of Common Stock of
rights or warrants to subscribe for or purchase any shares of stock of any class
or series or of any other rights or warrants;

(iii)  of any reclassification of Common Stock (other than a subdivision or
combination of the outstanding Common Stock, or a change in par value, or from
par value to no par value, or from no par value to par value), or of any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company shall be required, or of the sale or transfer
of all or substantially all of the assets of the Company or of any compulsory
share exchange whereby the Common Stock is converted into other securities, cash
or other property; or

(iv)  of the voluntary or involuntary dissolution, liquidation or winding up of
the Company;

then the Company shall (a) if any Preferred Securities are outstanding, cause to
be filed with the transfer agent for the Preferred Securities, and shall cause
to be mailed to the holders of record of the Preferred Securities, at their last
addresses as they shall appear upon the books and records of the Trust, or (b)
shall cause to be mailed to all Holders at their last addresses as they shall
appear in the Security Register, at least fifteen days prior to the applicable
record or effective date hereinafter specified, a notice stating (x) the date on
which a record (if any) is to be taken for the purpose of such dividend,
distribution, rights or warrants or, if a record is not to be taken, the date as
of which the holders of Common Stock of record to be entitled to such dividend,
distribution, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, share exchange, dissolution, liquidation or winding up (but no failure
to mail such notice or any defect therein or in the mailing thereof shall affect
the validity of the corporate action required to be specified in such notice).

Section 13.07  Adjustments in Case of Fundamental Changes.

(a)  Notwithstanding any other provision in this Article XIII to the contrary,
in the case of any Company Transaction involving a Fundamental Change, the
Applicable Conversion Price will be adjusted immediately after such Fundamental
Change as follows:

(i)  in the case of a Non-Stock Fundamental Change, the Applicable Conversion
Price of the Securities shall thereupon become the lower of (A) the Applicable
Conversion Price in effect immediately prior to such Non-Stock Fundamental
Change, but after giving effect to any other prior adjustments effected pursuant
to this Article XIII, and (B) the result obtained by multiplying the greater of
the Relevant Price or the then applicable Reference Market Price by the Optional
Redemption Ratio (such product shall hereinafter

                                      -68-
<PAGE>

be referred to as the "Adjusted Relevant Price" or the "Adjusted Reference
Market Price", as the case may be); and

(ii)  in the case of a Common Stock Fundamental Change, the Applicable
Conversion Price of the Securities in effect immediately prior to such Common
Stock Fundamental Change, but after giving effect to any other prior adjustments
effected pursuant to this Article XIII, shall thereupon be adjusted by
multiplying such Applicable Conversion Price by a fraction of which the
numerator shall be the Purchaser Stock Price and the denominator shall be the
Relevant Price; provided, however, that in the event of a Common Stock
Fundamental Change in which (A) 100% of the value of the consideration received
by a holder of Common Stock is common stock of the successor, acquiror or other
third party (and cash, if any, is paid only with respect to any fractional
interests in such common stock resulting from such Common Stock Fundamental
Change) and (B) all of the Common Stock shall have been exchanged for, converted
into or acquired for common stock (and cash with respect to fractional
interests) of the successor, acquiror or other third party, the Applicable
Conversion Price of the Securities in effect immediately prior to such Common
Stock Fundamental Change shall thereupon be adjusted by multiplying such
Applicable Conversion Price by a fraction of which the numerator shall be one
and the denominator shall be the number of shares of common stock of the
successor, acquiror, or other third party received by a stockholder for one
share of Common Stock as a result of such Common Stock Fundamental Change.

(b)  Definitions. The following definitions shall apply to terms used in this
Article XIII:

(1)  "Closing Price" of any security on any day shall mean on any day the last
reported sale price of such security on such day, or in case no sale takes place
on such day, the average of the closing bid and asked prices in each case on the
principal national securities exchange on which such securities are listed or
admitted to trading or, if not listed or admitted to trading on any national
securities exchange, on the NNM or, if such securities are not listed or
admitted to trading on any national securities exchange or quoted on the NNM,
the average of the closing bid and asked prices in the over-the-counter market
as furnished by any New York Stock Exchange member firm selected by the Company
for such purpose.

(2)  "Common Stock Fundamental Change" shall mean any Fundamental Change in
which more than 50% of the value (as determined in good faith by the Board of
Directors) of the consideration received by holders of Common Stock consists of
common stock that for each of the ten consecutive Trading Days immediately prior
to the Entitlement Date has been admitted for listing or admitted for listing
subject to notice of issuance on a national securities exchange or quoted on the
NNM; provided, however, that a Fundamental Change shall not be a Common Stock
Fundamental Change unless either (i) the Company continues to exist after the
occurrence of such Fundamental Change and the outstanding Preferred Securities
continue to exist as outstanding Preferred Securities, or (ii) not later than
the occurrence of such Fundamental Change, the outstanding Securities are
converted into

                                      -69-
<PAGE>

or exchanged for debentures of a corporation succeeding to the business of the
Company, which debentures have terms substantially similar to those of the
Securities.

(3)  "Entitlement Date" shall mean the record date for determination of the
holders of Common Stock entitled to receive securities, cash or other property
in connection with a Non-Stock Fundamental Change or a Common Stock Fundamental
Change or, if there is no such record date, the date upon which holders of
Common Stock shall have the right to receive such securities, cash or other
property.

(4)  "Fundamental Change" shall mean the occurrence of any transaction or event
in connection with a plan pursuant to which all or substantially all of the
Common Stock shall be exchanged for, converted into, acquired for or constitute
solely the right to receive securities, cash or other property (whether by means
of an exchange offer, liquidation, tender offer, consolidation, merger,
combination, reclassification, recapitalization or otherwise); provided,
however, in the case of a plan involving more than one such transaction or
event, for purposes of adjustment of the Applicable Conversion Price, such
Fundamental Change shall be deemed to have occurred when substantially all of
the Common Stock of the Company shall be exchanged for, converted into, or
acquired for or constitute solely the right to receive securities, cash or other
property, but the adjustment shall be based upon the highest weighted average
per share consideration that a holder of Common Stock could have received in
such transactions or events as a result of which more than 50% of the Common
Stock of the Company shall have been exchanged for, converted into, or acquired
for or constitute solely the right to receive securities, cash or other
property.

(5)  "Non-Stock Fundamental Change" shall mean any Fundamental Change other than
a Common Stock Fundamental Change.

(6)  "Optional Redemption Ratio" means a fraction of which the numerator shall
be $50 and the denominator will be the then current Optional Redemption Price
or, prior to December 20, 2002, an amount per Security determined by the Company
in its sole discretion, after consultation with an investment banking firm, to
be the equivalent of the hypothetical redemption price that would have been
applicable if the Securities had been redeemable during such period.

(7)  "Purchaser Stock Price" shall mean, with respect to any Common Stock
Fundamental Change, the average of the daily Closing Prices of the common stock
received in such Common Stock Fundamental Change for the ten (10) consecutive
Trading Days prior to and including the Entitlement Date, as adjusted in good
faith by the Board of Directors to appropriately reflect any of the events
referred to in subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of Section
13.03.

(8)  "Reference Market Price" shall initially mean on the date of original
issuance of the Securities, $20.17 (which is an amount equal to 66-2/3% of the
last reported sale price for the Common Stock on the New York Stock Exchange
Composite Tape on December 9, 1999 and, in the event of any adjustment to the
Applicable Conversion Price, other than as a result of a Non-Stock Fundamental
Change, the Reference Market Price shall

                                      -70-
<PAGE>

also be adjusted so that the ratio of the Reference Market Price to the
Applicable Conversion Price after giving effect to any such adjustment shall
always be the same as the ratio of $20.17 to the Initial Conversion Price.

(9)  "Relevant Price" shall mean (i) in the event of a Non-Stock Fundamental
Change in which the holders of the Common Stock receive only cash, the amount of
cash received by a stockholder for one share of Common Stock and (ii) in the
event of any other Non-Stock Fundamental Change or any Common Stock Fundamental
Change, the average of the daily Closing Prices of the Common Stock for the ten
(10) consecutive Trading Days prior to and including the Entitlement Date, in
each case, as adjusted in good faith by the Company to appropriately reflect any
of the events referred to in subparagraphs (i), (ii), (iii), (iv), (v) and (vi)
of Section 13.03.

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

Section 13.08  Dividend or Interest Reinvestment Plans.

(a)  Notwithstanding the foregoing provisions, the issuance of any shares of
Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Company and
the investment of additional optional amounts in shares of Common Stock under
any such plan, and the issuance of any shares of Common Stock or options or
rights to purchase such shares pursuant to any employee benefit plan or program
of the Company or pursuant to any option issued, shall not be deemed to
constitute an issuance of Common Stock or exercisable, exchangeable or
convertible securities by the Company to which any of the adjustment provisions
described above applies.

(b)  There shall also be no adjustment of the Applicable Conversion Price in
case of the issuance of any stock (or securities convertible into or
exchangeable for stock) of the Company except as specifically described in this
Article XIII.

Section 13.09  Certain Additional Rights.

     Notwithstanding any other provision of this Article XIII to the contrary,
rights, warrants, evidences of indebtedness, other securities, cash or other
assets (including, without limitation, any rights distributed pursuant to any
stockholder rights plan) shall be deemed not to have been distributed for
purposes of this Article XIII if the Company makes proper provision so that each
Holder who converts a Security (or any portion thereof) after the date fixed for
determination of stockholders entitled to receive such distribution shall be
entitled to receive upon such conversion, in addition to the shares of Common
Stock issuable upon such conversion, the amount and kind of such distributions
that such Holder would have been entitled to receive if such Holder had,
immediately prior to such determination date, converted such Security into
Common Stock.

                                      -71-
<PAGE>

Section 13.10  Restrictions on Common Stock Issuable Upon Conversion.

(a)  Shares of Common Stock to be issued upon conversion of a Security in
respect of Restricted Preferred Securities (as defined in the Declaration) shall
bear such restrictive legends as the Company may provide in accordance with
applicable law.

(b)  If shares of Common Stock to be issued upon conversion of a Security in
respect of Restricted Preferred Securities are to be registered in a name other
than that of the Holder of such Preferred Security, then the Person in whose
name such shares of Common Stock are to be registered must deliver to the
Conversion Agent a certificate satisfactory to the Company and signed by such
Person, as to compliance with the restrictions on transfer applicable to such
Preferred Security. Neither the Trustee nor any Conversion Agent or Registrar
shall be required to register in a name other than that of the Holder shares of
Common Stock or such Preferred Securities issued upon conversion of any such
Security in respect of such Preferred Securities not so accompanied by a
properly completed certificate.

Section 13.11  Trustee Not Responsible for Determining Conversion Price or
               Adjustments.

     Neither the Trustee nor any Conversion Agent shall at any time be under any
duty or responsibility to any Holder of any Security to determine whether any
facts exist which may require any adjustment of the Applicable Conversion Price,
or with respect to the nature or extent of any such adjustment when made, or
with respect to the method employed, or whether any supplemental indenture needs
to be entered into. Neither the Trustee nor any Conversion Agent shall be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock or of any securities or property, which may at any time
be issued or delivered upon the conversion of any Security; and neither the
Trustee nor any Conversion Agent makes any representation with respect thereto.
Neither the Trustee nor any Conversion Agent shall be responsible for any
failure of the Company to make any cash payment or to issue, transfer or deliver
any shares of Common Stock or stock certificates or other securities or property
upon the surrender of any Security for the purpose of conversion, or, except as
expressly herein provided, to comply with any of the covenants of the Company
contained in Article X or this Article XIII.

        IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

              Convertible Junior Subordinated Debenture Due 2029/3/



     1. Interest.  Hanover Compressor Company, a Delaware corporation (the
"Company"), is the issuer of this Convertible Junior Subordinated Debenture Due
2029 (the "Security") limited in aggregate principal amount to $              ,
                                                                --------------
issued under the Indenture hereinafter referred to. The Company promises to pay
interest on the Securities in cash from December 15, 1999 or from the most
recent interest payment date to which interest has been paid or duly provided
for, quarterly (subject to deferral for up to 20 consecutive quarters as
described in Section 3 hereof) in arrears on March 15, June 15, September 15,
and December 15 of each year (each such date, an "Interest Payment Date"),
commencing March 15, 2000, at the Applicable Rate, plus Additional Sums, if any,
until the principal hereof shall have become due and payable.

     The amount of interest payable for any period will be computed on the basis
of twelve 30-day months and a 360-day year. To the extent lawful, the Company
shall pay interest on overdue installments of interest (without regard to any
applicable grace period) at the rate borne by the Securities, compounded
quarterly. Any interest paid on this Security shall be increased to the extent
necessary to pay Additional Sums as set forth in this Security.

     2.  Additional Sums. The Company shall pay to Hanover Compressor Capital
Trust (and its permitted successors or assigns under the Declaration) (the
"Trust") such additional amounts as may be necessary in order that the amount of
dividends or other distributions then due and payable by the Trust on the
Preferred Securities that at any time remain outstanding in accordance with the
terms thereof shall not be reduced as a result of any additional taxes, duties,
assessments and other governmental charges of whatever nature (other than
withholding taxes) imposed by the United States or any other taxing authority.

     3.  Extension of Interest Payment Period. So long as no Event of Default
has occurred and is continuing, the Company shall have the right, at any time
during the term of this Security, from time to time to defer payments of
interest by extending the interest payment period of such Security for up to 20
consecutive quarters (a "Deferral Period"); provided that no Deferral Period may
extend beyond December 15, 2029.  To the extent permitted by applicable law,
interest, the payment of which has been deferred because of the extension of the
interest payment period pursuant to Section 3.13 of the Indenture, will bear
interest thereon at the Applicable Rate compounded quarterly for each quarter of
the Deferral Period ("Compounded Interest"). On the applicable Payment
Resumption Date, the Company shall pay all interest then accrued and unpaid on
the Securities, including any Compounded Interest that shall be payable to the
Holders of the Securities in whose names the Securities are registered in the
Security Register on the record date fixed for such Payment Resumption Date.
Before the termination of any Deferral Period, the Company may further


- ---------------------

/3/ All terms used in this Security which are defined in the Indenture or in the
    Declaration referred to herein shall have the meanings assigned to them in
    the Indenture or the Declaration, as the case may be.

                                      -79-
<PAGE>

extend such period as provided in the Indenture, provided that such period
together with all such further extensions thereof shall not exceed 20
consecutive quarters or extend beyond the Stated Maturity of the Security. Upon
the termination of any Deferral Period and upon the payment of all Compounded
Interest and Additional Sums (together, "Additional Payments"), if any, then
due, the Company may commence a new Deferral Period, subject to the foregoing
requirements. No interest shall be due and payable during a Deferral Period
except on the applicable Payment Resumption Date.

     The Company shall give the Holder of the Security and the Trustee written
notice (a "Deferral Notice") of its selection of a Deferral Period at least ten
days prior to the record date for any distributions that would have been payable
on the Trust Securities except for the decision to begin or extend such Deferral
Period. The Company may elect to pay all interest then accrued and unpaid on the
Securities, including Compound Interest, on an Interest Payment Date prior to
its most recently established Payment Resumption Date, provided that the Company
gives the Holder of the Security and the Trustee a new Deferral Notice setting
forth the revised Payment Resumption Date at least three Business Days prior to
the Regular Record Date for such revised Payment Resumption Date.

     The quarter in which any Deferral Notice is given pursuant to the second
paragraph of this Section 3 shall be counted as one of the 20 quarters permitted
in the maximum Deferral Period permitted under the first paragraph of this
Section 3.

     4.  Method of Payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the regular record date
for such interest installment, which shall be the close of business on the first
day of the month of each Interest Payment Date (the "Regular Record Date"),
commencing March 1, 2000.  Any such interest not so punctually paid or duly
provided for shall forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than ten days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture,
provided that any such payment will be made in such coin or currency of the
United States of America which at the time of payment is a legal tender for
payment of public and private debts.

     Payment of the principal of and interest on this Security will be made at
the office or agency of the Company maintained for that purpose in New York, New
York, in coin or currency of the United States of America which at the time of
payment is legal tender for payment of public and private debts; provided,
however, that at any time that the Property Trustee is not the sole holder of
the Securities, payment of interest may, at the option of the Company, be made
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or by wire transfer.

                                      -80-

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

     6. Indenture. The Company issued the Securities under an indenture, dated
as of December 15, 1999 (the "Indenture"), between the Company and Wilmington
Trust Company, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered. The terms of the
Securities include those stated in the Indenture and those made part of the
Indenture by the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-
77bbbb) ("Trust Indenture Act") as in effect on the date of the Indenture. The
Securities are subject to, and qualified by, all such terms, certain of which
are summarized herein, and holders are referred to the Indenture and the Trust
Indenture Act for a statement of such terms. The Securities are unsecured
general obligations of the Company limited to up to $              and
                                                     ------------
subordinated in right of payment to all existing and future Senior Debt of the
Company. No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed or to convert this Security as provided in the Indenture.

     7.  Optional Redemption. The Securities are redeemable at the Company's
option (an "Optional Redemption") in whole or in part, at any time or from time
to time, on or after December 20, 2002, at a Redemption Price equal to the
applicable price per $50 principal amount of Securities set forth in the table
below, plus any accrued and unpaid interest, including Additional Payments, if
any, to the Redemption Date, if redeemed during the 12-month period ending on
December 19:

2006                                  $50.00
</TABLE>

and thereafter at $50 per $50 principal amount of the Securities plus, in each
case, any accrued and unpaid interest, including Additional Payments, if any, to
the Redemption Date.

     8.  Optional Redemption Upon Tax Event. Subject to the conditions set forth
in the Indenture, the Securities are subject to redemption in whole, but not in
part, if a Tax Event shall occur and be continuing, at any time within 90 days
following the occurrence of such Tax Event, at a Redemption Price equal to $50
per $50 principal amount thereof, plus accrued but unpaid interest, including
Additional Payments, if any, to the Redemption Date.

     In lieu of the foregoing, the Company also shall have the option of causing
the Securities to remain outstanding and pay Additional Sums on the Securities.

                                      -81-
<PAGE>

     9.  Notice of Redemption. Notice of redemption will be mailed by first-
class mail, postage prepaid, at least 20 days, but not more than 60 days before
the Redemption Date to each Holder of the Securities to be redeemed at such
Holder's address appearing in the Security Register.

     10.  No Sinking Fund.  There are no sinking fund payments with respect to
the Securities.

     11.  Payment to Registered Holders; Cessation of Interest Accrual Upon
Redemption. If this Security is redeemed subsequent to a Regular Record Date
with respect to any Interest Payment Date specified above and on or prior to
such Interest Payment Date, then any accrued interest will be paid to the person
in whose name this Security is registered at the close of business on such
record date. On or after the Redemption Date, interest will cease to accrue on
the Securities, or portion thereof, called for redemption.

     12.  Subordination. The payment of the principal of, interest on or any
other amounts due on the Securities is subordinated in right of payment to all
existing and future Senior Debt (as defined below) of the Company, as described
in the Indenture. Each Holder, by accepting a Security, agrees to such
subordination and authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and appoints the Trustee as its attorney-in-fact for such purpose.

     "Senior Debt" means (i) the principal of, premium, if any,  and interest,
on all obligations of every nature of the Company for money borrowed, whether
outstanding on the date of execution of the Indenture or thereafter created,
assumed or incurred, together with all fees, indemnities and expenses payable
under such obligations, (ii) all obligations to make payment pursuant to the
terms of financial instruments, such as (a) securities contracts and foreign
currency exchange contracts, (b) derivative instruments, such as swap agreements
(including interest rate and foreign exchange rate swap agreements), cap
agreements, floor agreements, collar agreements, interest rate agreements,
foreign exchange agreements, options, commodity futures contracts and commodity
options contracts, and (c) similar financial instruments; except, in the case of
both (i) and (ii) above, such indebtedness and obligations that are expressly
stated to rank junior in right of payment to, or pari passu in right of payment
with, the Securities, (iii) indebtedness or obligations of others of the kind
described in both (i) and (ii) above for the payment of which the Company is
responsible or liable as guarantor or otherwise, and (iv) deferrals, renewals or
extensions of any such Senior Debt; provided, however, that Senior Debt shall
not be deemed to include (a) any Debt of the Company which, when incurred and
without respect to any election under Section 1111(b) of the United States
Bankruptcy Code of 1978, was without recourse to the Company, (b) trade accounts
payable and accrued liabilities arising in the ordinary course of business, (c)
any Debt of the Company to any of its subsidiaries, (d) Debt to any employee of
the Company and (e) Debt which by its terms is subordinated to trade accounts
payable or accrued liabilities arising in the ordinary course of business to the
extent that payments made to the holders of such Debt by the Holders of the
Securities as a result of the subordination provisions of the Indenture would be
greater than such payments otherwise would have been as a result of any
obligation of such holders of such Debt to pay amounts over to the obligees on
such trade accounts payable or accrued liabilities arising in the ordinary
course of business as a result of subordination provisions to which such Debt is
subject.

                                      -82-

     13.  Conversion.  The Holder of any Security has the right, exercisable at
any time prior to 5:00 p.m., New York City time, on the Business Day immediately
preceding December 15, 2029, to convert the principal amount thereof (or any
portion thereof that is an integral multiple of $50) into shares of Common Stock
at the initial conversation rate of 1.3986 shares of Common Stock for each $50
in aggregate principal amount of Securities (equivalent to a conversion price of
$35.75 per share of Common Stock of the Company). The conversion ratio and
equivalent conversion price in effect at any time are known as the "Applicable
Conversion Price" and the "Applicable Conversion Ratio," respectively, and are
subject to adjustment under certain circumstances. If a Security is called for
redemption, the conversion right will terminate at the close of business on the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

     To convert a Security, a Holder must (1) complete and sign a conversion
notice substantially in the form attached hereto, (2) surrender the Security to
a Conversion Agent, (3) furnish appropriate endorsements or transfer documents
if required by the Security Registrar or Conversion Agent and (4) pay any
transfer or similar tax, if required. Upon conversion, no adjustment or payment
will be made for interest or dividends, but if any Holder surrenders a Security
for conversion after the close of business on the Regular Record Date for the
payment of an installment of interest and prior to the opening of business on
the next Interest Payment Date, then, notwithstanding such conversion, the
interest payable on such Interest Payment Date will be paid to the registered
Holder of such Security on such Regular Record Date. In such event, such
Security, when surrendered for conversion, need not be accompanied by payment of
an amount equal to the interest payable on such Interest Payment Date on the
portion so converted. The number of shares issuable upon conversion of a
Security is determined by dividing the principal amount of the Security
converted by the Applicable Conversion Price in effect on the Conversion Date.
No fractional shares will be issued upon conversion but a cash adjustment will
be made for any fractional interest.  The outstanding principal amount of any
Security shall be reduced by the portion of the principal amount thereof
converted into shares of Common Stock.

     14.  Registration Rights. The holders of the Preferred Securities, the
Securities, the Guarantee Agreement and the shares of Common Stock of the
Company issuable upon conversion of the Securities (collectively, the
"Registrable Securities") are entitled to the benefits of a Registration Rights
Agreement, dated as of December 15, 1999, among the Company, the Trust and the
Initial Purchasers (the "Registration Rights Agreement").  Pursuant to the
Registration Rights Agreement the Company and the Trust have agreed for the
benefit of the holders of the Registrable Securities that (i) they will, at the
Company's sole expense, prior to February 15, 2000, file a shelf registration
statement (the "Shelf Registration Statement") with the Commission with respect
to resales of the Registrable Securities, (ii) they will use their best efforts
to cause such Shelf Registration Statement to be declared effective under the
Securities Act prior to May 15, 2000, and (iii) they will use their best efforts
to maintain such Shelf Registration Statement continuously effective under the
Securities Act (subject to certain exceptions under the Registration Rights
Agreement) until the second anniversary of the effectiveness of the Shelf
Registration Statement or such other period as shall be required under Rule
144(k) thereunder or any successor rule or regulation thereto or such earlier
date as is provided in the Registration Rights Agreement. If the Company fails
to comply with either of clauses (ii) or (iii) above, subject to certain
exceptions provided in the Registration Rights Agreement, (a "Registration
Default") then, at such time, the

                                      -83-
<PAGE>

Applicable Rate will increase by 50 basis points (.50%). Such increase will
remain in effect from and including the date on which any such Registration
Default shall occur to but excluding the date on which all Registration Defaults
have been cured, on which date the interest rate on the Securities will revert
to the interest rate originally borne by the Securities.

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

     The Securities are issuable only in registered form without coupons in
denominations of $50 and integral multiples thereof. No service charge shall be
made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Prior to due presentment of this
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary. In the event of redemption or conversion of
this Security in part only, a new Security or Securities for the unredeemed or
unconverted portion hereof will be issued in the name of the Holder hereof upon
the cancellation hereof.

     16.  Persons Deemed Owners.  Except as provided in Section 3 hereof, the
registered Holder of a Security may be treated as its owner for all purposes.

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

     18.  Events of Default and Remedies. The Securities shall have the Events
of Default as set forth in Section 5.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the Holders of at least 25% in aggregate
principal amount of the Outstanding Securities by notice to the Company and the
Trustee may declare all amounts payable on the Securities (including any
Additional Payments) to be due and payable immediately; provided that, if the
Property Trustee is the sole Holder of the Security and if upon an Event of
Default, the Trustee or the Holder of not less than 25% in aggregate principal
amount of the then outstanding Securities fail to declare the principal of all
the Securities to be immediately due and payable, the Holders of at least 25% in
aggregate liquidation amount of Preferred Securities then outstanding shall have
such right by a notice in writing to the Company and the Trustee; and upon any
such declaration such principal and all accrued interest shall become

                                      -84-
<PAGE>

immediately due and payable; and provided further that the payment of principal
and interest on such Securities shall remain subordinated to the extent provided
in the Indenture.

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

     Holders may not enforce the Indenture or the Securities except as provided
in the Indenture. Subject to certain limitations, Holders of a majority in
principal amount of the then outstanding Securities issued under the Indenture
may direct the Trustee in its exercise of any trust or power. The Company must
furnish annually compliance certificates to the Trustee. The above description
of Events of Default and remedies is qualified by reference to, and subject in
its entirety by, the more complete description thereof contained in the
Indenture.

     19.  Amendments, Supplements and Waivers. The Indenture permits, subject to
the rights of the holders of Preferred Securities set forth therein and in the
Declaration and with certain other exceptions as therein provided, the amendment
thereof and the modification of the rights and obligations of the Company, and
the rights of the Holders of the Securities under the Indenture, at any time, by
the Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Securities at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, subject to the
rights of the holders of the Preferred Securities set forth therein and in the
Declaration, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security. The above description of amendments, supplements and
waivers is qualified by reference to, and subject in its entirety, by the more
complete description thereof contained in the Indenture.

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

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

                                      -85-
<PAGE>

     22.  Governing Law.  THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE SECURITIES.

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

     24.  Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     25.  The Company will furnish to any Holder of the Securities upon written
request and without charge a copy of the Indenture. Request may be made to:

                Powers, Duties and Rights of Guarantee Trustee

SECTION 3.01  Powers, Duties and Rights of Guarantee Trustee.

          (a) This Guarantee shall be held by the Guarantee Trustee for the
benefit of the Holders, and the Guarantee Trustee shall not transfer this
Guarantee to any Person except a Holder exercising his or her rights pursuant to
Section 5.05(d) or to a Successor Guarantee Trustee on acceptance by such
Successor Guarantee Trustee of its appointment to act as Successor Guarantee
Trustee. The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor Guarantee Trustee, and such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

          (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee for the benefit of the Holders.

          (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee, and no implied covenants shall be read into this Guarantee
against the Guarantee Trustee. In case an Event of Default has occurred (that
has not been cured or waived pursuant to Section 2.06) and is known to the
Guarantee Trustee, the Guarantee Trustee shall exercise such of the rights and
powers vested in it by this 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.

                                       6

          (d) No provision of this Guarantee shall be construed to relieve the
Guarantee Trustee from liability for its own negligent action, its own negligent
failure to act, 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 Guarantee Trustee shall be
          determined solely by the express provisions of this Guarantee, and the
          Guarantee Trustee shall not be liable except for the performance of
          such duties and obligations as are specifically set forth in this
          Guarantee, and no implied covenants or obligations shall be read into
          this Guarantee against the Guarantee Trustee; and

               (B) in the absence of bad faith on the part of the Guarantee
          Trustee, the 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 Guarantee
          Trustee and conforming to the requirements of this Guarantee; but in
          the case of any such certificates or opinions that by any provision
          hereof are specifically required to be furnished to the Guarantee
          Trustee, the Guarantee Trustee shall be under a duty to examine the
          same to determine whether or not they conform to the requirements of
          this Guarantee;

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

               (iii)  the 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 not less than 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 Guarantee Trustee, or exercising any trust or power conferred upon the
     Guarantee Trustee under this Guarantee; and

               (iv) no provision of this Guarantee shall require the 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.

SECTION 3.02  Certain Rights of Guarantee Trustee.

          a)   Subject to the provisions of Section 3.01:

               (i) the Guarantee 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,

                                       7

     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 Guarantor contemplated by this
     Guarantee shall be sufficiently evidenced by an Officers' Certificate;

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

               (iv) the Guarantee Trustee shall have no duty to see to any
     recording, filing or registration of any instrument (or any rerecording,
     refiling or reregistration thereof);

               (v) the Guarantee Trustee may consult with legal counsel of its
     selection, and the written advice or opinion of such legal counsel with
     respect to legal matters shall be full and complete authorization and
     protection in respect of any action taken, suffered or omitted to be taken
     by it hereunder in good faith and in accordance with such advice or
     opinion. Such legal counsel may be legal counsel to the Guarantor or any of
     its Affiliates and may include any of the Guarantor's employees.  The
     Guarantee Trustee shall have the right at any time to seek instructions
     concerning the administration of this Guarantee from any court of competent
     jurisdiction;

               (vi) the Guarantee Trustee shall be under no obligation to
     exercise any of the rights or powers vested in it by this Guarantee at the
     request or direction of any Holder, unless such Holder shall have provided
     to the Guarantee Trustee security and indemnity satisfactory to the
     Guarantee Trustee against the costs, expenses (including attorneys' fees
     and expenses) 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 Guarantee Trustee; provided that nothing contained in
     this Section 3.02(a)(vi) shall be taken to relieve the Guarantee Trustee,
     upon the occurrence of an Event of Default known to the Guarantee Trustee,
     of its obligation to exercise the rights and powers vested in it by this
     Guarantee;

               (vii)  the Guarantee 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 Guarantee Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit; the reasonable expense of every such
     investigation shall be paid by the Guarantor or, if paid by the Guarantee
     Trustee, shall be repaid by the Guarantor upon request, except any such
     expense  as may be attributable to the Guarantee Trustee's negligence or
     bad faith;

               (viii)  the Guarantee Trustee may execute any of the trusts or
     powers hereunder or perform any duties hereunder either directly or by or
     through agents or

                                       8
<PAGE>

     attorneys, and the 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 Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the Guarantee
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action; it being understood that no third party shall be required
     to inquire as to the authority of the Guarantee Trustee to so act or as to
     its compliance with any of the terms and provisions of this Guarantee, both
     of which shall be conclusively evidenced by the Guarantee Trustee's or its
     agent's taking such action;

               (x) whenever in the administration of this Guarantee the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (i) may request written instructions from
     the Holders or, other than with respect to enforcing any remedy or right or
     taking any action related thereto, the Guarantor, (ii) may refrain from
     enforcing such remedy or right or taking such other action until such
     written instructions are received, and (iii) shall be protected in acting
     in accordance with such written instructions; and

               (xi) the Guarantee Trustee shall not be charged with knowledge of
     any default or Event of Default hereunder unless a Responsible Officer of
     the Guarantee Trustee shall have knowledge of the default or Event of
     Default.

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

SECTION 3.03  Not Responsible for Recitals or Issuance of Guarantee.

     The recitals contained in this Guarantee shall be taken as the statements
of the Guarantor, and the Guarantee Trustee does not assume any responsibility
for their correctness. The Guarantee Trustee makes no representations as to the

     The Guarantor agrees:

     (a) to pay the Guarantee Trustee from time to time such reasonable
compensation as the Guarantor and the Guarantee Trustee shall from time to time
agree in writing 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);

                                       9

     (b) except as otherwise expressly provided herein, to reimburse the
Guarantee Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Guarantee Trustee in accordance with the
provisions of this Guarantee (including the reasonable compensation and expenses
of its agents and counsel), except any such expense, disbursement or advance as

     As security for the performance of the obligations of the Guarantor under
this Section 3.04, the Guarantee Trustee shall have a lien, prior to the
Preferred Securities, upon all the property and funds held or collected by the
Guarantee Trustee as such, except funds held in trust for the payment of
principal of, and premium (if any) or interest on, particular obligations of the
Guarantor under this Guarantee.

     The provisions of this Section 3.04 shall survive the termination of this
Guarantee.

 SECTION 4.01  Guarantee Trustee; Eligibility.

          (a) There shall at all times be a Guarantee Trustee which shall:

               (i) not be an Affiliate of the Guarantor; and

               (ii) be a corporation organized and doing business under the laws

     U.S. dollars ($50,000,000), and 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 4.01(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 Guarantee Trustee shall cease to be eligible to
so act under Section 4.01(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.02(c).

          (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 3.10(b) of the Trust Indenture Act, the

or removed without cause at any time by the Guarantor.

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

accepted such appointment by written instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor.

          (c) The Guarantee Trustee appointed to office shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or

Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

          (d) If no Successor Guarantee Trustee shall have been appointed and

a Successor Guarantee Trustee.

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

          (f) Upon termination of this Guarantee or removal or resignation of
the Guarantee Trustee pursuant to this Section 4.02, the Guarantor shall pay to

SECTION 5.01  Guarantee.

     The Guarantor irrevocably and unconditionally agrees to pay in full on a
subordinated basis to the Holders the Guarantee Payments (without duplication of
amounts theretofore paid by or on behalf of the Issuer), as and when due, in
coin or currency of the United States of America which at the time of payment is
legal tender for payment of public and private debt regardless of any defense,
right of setoff or counterclaim that the Issuer may have or assert other than
the defense of payment. 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  Subordination.

     If a Debenture Event of Default or a Declaration Event of Default (or an
event that, with passage of time, would become a Debenture Event of Default)
shall have occurred and be continuing, the rights of holders of the Common
Securities to receive Guarantee Payments under the Common Securities Guarantee
are subordinated to the rights of Holders to receive Guarantee Payments under
this Guarantee.

SECTION 5.03  Waiver of Notice and Demand.

     The Guarantor hereby waives notice of acceptance of this Guarantee and of
any liability to which it applies or may apply, presentment, demand for payment,

before proceeding against the Guarantor, protest, notice of nonpayment, notice
of dishonor, notice of redemption and all other notices and demands.

SECTION 5.04  Obligations Not Affected.

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

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) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, the amount payable upon redemption or the amount
payable upon liquidation of the Issuer or any other sums payable under the terms
of the Preferred Securities or the extension of time for the performance of any
other obligation under, arising out of, or in connection with, the Preferred
Securities (other than an extension of time for payment of Distributions that
results from the extension of any interest payment period on the Debentures
permitted by the Indenture);

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

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

Issuer;

<PAGE>

          (g) any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.04 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

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

SECTION 5.05  Rights of Holders.

held for the benefit of the Holders.

          (b) The Guarantee Trustee has the right to enforce this Guarantee on
behalf of the Holders.

          (c) 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

Guarantee or exercising any trust or power conferred upon the Guarantee Trustee
under this Guarantee.

          (d) Any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee, without first instituting
a legal proceeding against the Issuer, the Guarantee Trustee or any other
Person.

SECTION 5.06  Guarantee of Payment.

     This Guarantee creates a guarantee of payment and not of collection. This
Guarantee will not be discharged except by payment of the Guarantee Payments in
full (without duplication of amounts theretofore paid by the Issuer) or upon
distribution of Debentures to Holders as provided in the Declaration.

SECTION 5.07  Subrogation.

     The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Guarantee and shall have the right to waive payment by the
Issuer pursuant to Section 5.01; 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 Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this 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 5.08  Independent Obligations.

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Preferred Securities, and

Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the
occurrence of any event referred to in subsections (a) through (g), inclusive,
of Section 5.04 hereof.

SECTION 5.09  Conversion.

     The Guarantor acknowledges its obligation to issue and deliver common stock
upon the conversion of the Preferred Securities.

     So long as any Preferred Securities remain outstanding, if there shall have
occurred and be continuing a Debenture Event of Default, a Declaration Event of
Default or an event that, with the giving of notice or the lapse of time or
both, would constitute a Debenture Event of Default or a Declaration Event of
Default, or a selection by the Guarantor of a Deferral Period as provided in the
Indenture and such period, or any extension thereof, shall be continuing, then
(a) the Guarantor shall not declare or pay any dividend on, or make any
distribution with respect to, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock (other than stock dividends
paid by the Guarantor which stock dividends consist of the stock of the same

make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Guarantor which rank pari
passu with or junior in interest to the Debentures and (c) the Guarantor shall
not make any guarantee payments with respect to any guarantee by the Guarantor
of the debt securities of any subsidiary of the Guarantor if such guarantee
ranks pari passu with or junior in interest to the Debentures (in each case,
other than (A) dividends or distributions in Common Stock, (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
this Guarantee and the Common Securities Guarantee, (D) purchases or
acquisitions of shares of Common Stock in connection with the satisfaction by
the Guarantor of its obligations under any employee benefit plan or any other
contractual obligation of the Guarantor (other than a contractual obligation
ranking pari passu with or junior in interest to the Debentures), (E) as a
result of a reclassification of the Guarantor's capital stock or the exchange or
conversion of one class or series of the Guarantor's capital stock for another
class or series of the Guarantor's capital stock or (F) 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).

SECTION 6.02  Ranking.

     This Guarantee will constitute an unsecured obligation of the Guarantor and
will rank subordinate to all Senior Debt of the Guarantor to the same extent
that the Debentures are subordinated pursuant to the Indenture.

                                  ARTICLE VII

                                  Termination

SECTION 7.01  Termination.

     This Guarantee shall terminate upon (i) full payment of the amount payable

Guarantor's common stock to the Holders in respect of the conversion of the
Preferred Securities into the Guarantor's common stock, (iii) the distribution
of the Debentures to the Holders of all of the Preferred Securities or (iv) full
payment of the amounts payable in accordance with the Declaration upon
liquidation of the Issuer. Notwithstanding the foregoing, this Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any Holder must restore payment of any sums paid under the Preferred
Securities or under this Guarantee.

                                 ARTICLE VIII

in damages or otherwise to the Guarantor or any Covered Person for any loss,

by such Indemnified Person in good faith in accordance with this Guarantee and
in a manner that such Indemnified Person reasonably believed to be within the
scope of the authority conferred on such Indemnified Person by this Guarantee or
by law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's negligence or
willful misconduct with respect to such acts or omissions.

          (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,
reports or statements presented to the Guarantor 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 Guarantor, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,

expense including taxes (other than taxes based on the income of such
Indemnified Person) incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including

"Declaration"), dated as of December 15, 1999, among the trustees of the Issuer
named therein, the Guarantor, as sponsor, and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer may issue

     WHEREAS, pursuant to the Declaration, the Issuer may issue up to 53,351
Common Securities, having an aggregate stated liquidation amount of up to

covenant, term or condition relating to the Common Securities to be performed or

<PAGE>

Securities (other than an extension of time for payment of Distributions, that

permitted by the Indenture);

     (c) any failure, omission, delay or lack of diligence on the part of the

conferred on the Holders pursuant to the terms of the Common Securities, or any

 hereby incurred;

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

SECTION 2.05  Rights of Holders.

     The Guarantor expressly acknowledges that any Holder may institute a legal
proceeding directly against the Guarantor to enforce its rights under this
Common Securities Guarantee, without first instituting a legal proceeding
against the Issuer or any other Person.

SECTION 2.06  Guarantee of Payment.

     This Common Securities Guarantee creates a guarantee of payment and not of
collection. This Common Securities Guarantee will not be discharged except by
payment of the Guarantee Payments in full (without duplication of amounts

provided in the Declaration.

SECTION 2.07  Subrogation.

     The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Common Securities Guarantee and shall have right to waive
payment by the Issuer pursuant to Section 2.01; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any

                                       5
<PAGE>

indemnity, reimbursement or other agreement, in all cases as a result of payment
under this Common Securities Guarantee, if, at the time of any such payment, any

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 2.08  Independent Obligations.

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Common Securities and that
the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Common Securities Guarantee
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 2.04 hereof.

SECTION 2.09  Conversion.

     The Guarantor acknowledges its obligation to issue and deliver common stock
upon the conversion of the Common Securities.

SECTION 2.10  Events of Default; Waiver.

     The Holders of a majority in liquidation amount of Common Securities may by
vote, on behalf of the Holders of all of the Common securities, waive any past
Guarantee Event of Default and its consequences.  Upon such waiver, any such
Guarantee Event of Default shall cease to exist, and any Guarantee Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Common Securities Guarantee, but no such waiver shall extend to any
subsequent or other default or Guarantee Event of Default or impair any right
consequent thereon.

     So long as any Common Securities remain outstanding, if (i) there shall
have occurred and be continuing a Debenture Event of Default, a Declaration
Event of Default or an event that, with the giving of notice or the lapse of
time or both, would constitute a Debenture Event of Default or a Declaration
Event of Default or (ii) a selection by the Guarantor of a Deferral Period as
provided in the Indenture and such period, or any extension thereof, shall be
continuing, then (a) the Guarantor shall not declare or pay any dividend on, or
make any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than stock
dividends paid by the Guarantor which consist of the stock of the same class as
that on which the dividend is being paid), (b) the Guarantor shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by the Guarantor which rank pari passu with or
junior in interest to the Debentures and (c) shall not make any guarantee
payments with respect to any guarantee by the Guarantor of the debt securities
of any

                                       6

subsidiary of the Guarantor if such guarantee ranks pari passu with or junior in

under any such plan in the future, or the redemption or repurchase of any such
rights pursuant thereto, (C) payments under the Guarantee and the Common

Guarantor=s capital stock or the exchange or conversion of one class or series
of the Guarantor=s capital stock for another class or series of the Guarantor=s
capital stock or (F) 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).

SECTION 3.02  Ranking.

     This Common Securities Guarantee will constitute an unsecured obligation of
the Guarantor and will rank subordinate to all Senior Debt of the Guarantor to
the same extent that the Debentures (as defined in the Indenture) are
subordinated pursuant to the Indenture.

                                  ARTICLE IV

distribution of the Debentures to the Holders in exchange for all of the Common
Securities or (iv) full payment of the amounts payable in accordance with the
Declaration upon liquidation of the Issuer. Notwithstanding the foregoing, this

as the case may be, if at any time any Holder of Common Securities must restore
payment of any sums paid under the Common Securities or under this Common
Securities Guarantee.

<PAGE>

Shelf Registration Statement, promptly upon the request of any Holder that is
not then an Electing Holder to take any action reasonably necessary to register
the sale of any Securities of such Holder and to identify such Holder as a
selling securityholder, provided, however, that nothing in this subparagraph
shall relieve such Holder of the obligation to provide the Company and the Trust
with the information required pursuant to Section 2(c) hereof.

     (2)      (i) No Holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement as of the date on which the
Commission declares the Shelf Registration Statement effective or on which the
Shelf Registration Statement otherwise becomes effective, and no Holder shall be
entitled to use the Prospectus forming a part thereof for resales of Registrable
Securities at any time, unless such holder has provided the Company and the
Trust with such information as they shall reasonably request in order to enable
the Company and the Trust to comply with the applicable requirements of the
Securities Act in connection with offers and sales by such Holder as a selling
securityholder in the Shelf Registration Statement within 30 calendar days from
the date on which any such request is first mailed to such Holder. Each Holder
as to which any Shelf Registration is being effected agrees to furnish promptly
to the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

              (ii) After the date on which the Commission declares the Shelf
Registration Statement effective or on which the Shelf Registration Statement
otherwise becomes effective, the Company and the Trust may, upon the request of
any Holder of Registrable Securities that is not then an Electing Holder, take
such action as is necessary to name such Holder as a selling security holder in
the Shelf Registration Statement or to enable such Holder to use the Prospectus
forming a part thereof for resales of Registrable Securities if such Holder
promptly provides the Company and the Trust with such information as they shall
reasonably request in order to enable the Company and the Trust to comply with
the applicable requirements of the Securities Act in connection with offers and
sales by such Holder so as to permit such Holder to be so named. Each Holder as
to which any Shelf Registration is being effected agrees to furnish promptly to
the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

          (iii)  The term "Electing Holder" shall mean any holder of
Registrable Securities that has complied with the requests of the Company and
the Trust in accordance with Section 2(c)(i) or 2(c)(ii) hereof.

     3.  Registration Procedures.  In connection with any Shelf Registration
Statement, the following provisions shall apply:

         (1)   The Trust and the Company shall furnish to each Purchaser,
prior to the filing thereof with the Commission, a copy of any Shelf
Registration Statement, and each amendment thereof and each amendment or
supplement, if any, to the Prospectus included therein and shall each use its
best efforts to reflect in each such document, when so filed with the
Commission, such comments as such Purchaser reasonably may propose.

<PAGE>

         (2)   The Trust and the Company shall take such action as may be
necessary, subject to Section 7(b) hereof, so that (i) any Shelf Registration
Statement and any amendment thereto and any Prospectus forming part thereof and
any amendment or supplement thereto (and each report or other document
incorporated therein by reference in each case) complies in all material
respects with the Securities Act and the Exchange Act and the respective rules
and regulations thereunder, (ii) any Shelf Registration Statement and any
amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) any Prospectus forming part of any Shelf Registration Statement, and any
amendment or supplement to such Prospectus, does not, during the Shelf
Registration Period, include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements, in the light of
the circumstances under which they were made, not misleading.


         (3)   The Company shall advise each Purchaser and each Electing
     Holder and, if requested by such Purchaser or any such Electing Holder in
     writing, confirm such advice in writing:

                 (1)  when a Shelf Registration Statement and any amendment
thereto has been filed with the Commission and when the Shelf Registration
Statement or any post-effective amendment thereto has become effective; and

                 (2)  of any request by the Commission for amendments or
     supplements to the Shelf Registration Statement or the Prospectus included
     therein or for additional information.

          (2)  The Trust and the Company shall advise each Purchaser and each
     Electing Holder and, if requested by such Purchaser or any such Electing
     Holder in writing, confirm such advice in writing:

                 (3)  of the issuance by the Commission of any stop order
     suspending the effectiveness of the Shelf Registration Statement or the
     initiation of any proceedings for that purpose;

                 (4)  of the receipt by the Trust or the Company of any
     notification with respect to the suspension of the qualification of the
     securities included therein for sale in any jurisdiction or the initiation
     or threatening of any proceeding for such purpose; and

                 (5)  of the happening, during the Shelf Registration Period,
of any event (provided that such notice need not specify the nature of such
event) that requires the making of any changes in the Shelf Registration
Statement or the Prospectus so that, as of such date, the Registration Statement
and the Prospectus do not contain an untrue statement of a material fact and do
not omit to state a material fact required to be stated therein or necessary to
make the statements therein (in the case of the Prospectus, in light of the
circumstances under which they were made) not misleading (which advice shall be

                                       6
<PAGE>

accompanied by an instruction to suspend the use of the Prospectus until the
requisite changes have been made).

                (3) Written notice pursuant to Section 3(c)(1)(ii) and Section
3(c)(2)(i)-(iii) shall be accompanied by an instruction to suspend the use of
the prospectus until the requisite changes have been made.

         (4)   The Trust and the Company shall use their reasonable best
efforts to prevent the issuance, and if issued to obtain the withdrawal, of any
order suspending the effectiveness of any Shelf Registration Statement at the
earliest possible time.

         (5)   The Trust and the Company shall furnish to each Electing Holder
of Securities, without charge, at least one copy of such Shelf Registration
Statement and any post-effective amendment thereto (including any reports or
other documents incorporated therein by reference), including financial
statements and schedules, and, if the Electing Holder so requests in writing,
all exhibits thereto (including those incorporated by reference).

         (6)   The Trust and the Company shall, during the Shelf Registration
Period, deliver to each Electing Holder, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in such Shelf
Registration Statement and any amendment or supplement thereto as such Electing
Holder may reasonably request and shall deliver such materials to the New York
Stock Exchange pursuant to Rule 153 under the Act; and each of the Trust and the
Company consents to the use of the Prospectus or any amendment or supplement
thereto by each of the Electing Holders in connection with the offering and sale
of the Securities covered by the Prospectus or any amendment or supplement
thereto during the Shelf Registration Period.

         (7)   Prior to any offering of Securities pursuant to any Shelf
Registration Statement, the Trust and the Company shall register or qualify or
cooperate with the Electing Holders and their respective counsel in connection
with the registration or qualification of such Securities for offer and sale
under the securities or blue sky laws of such jurisdictions as any such Electing
Holders reasonably request in writing and do any and all other acts or things
necessary or advisable to enable the offer and sale in such jurisdictions of the
Securities covered by such Shelf Registration Statement; provided, however, that
neither the Trust nor the Company will be required to qualify generally to do
business in any jurisdiction where it is not then so qualified or to take any
action which would subject it to general service of process or to taxation in
any such jurisdiction where it is not then so subject.

          (8)  Unless the applicable Securities shall be in book-entry only
form, the Trust and the Company shall cooperate with the Electing Holders to
facilitate the timely preparation and delivery of certificates representing
Securities to be sold pursuant to any Shelf Registration Statement free of any
restrictive legends and in such permitted denominations and registered in such
names as Electing Holders may request in connection the sale of Securities
pursuant to such Shelf Registration Statement.

<PAGE>

         (9)   Upon the occurrence of any event contemplated by Section
3(c)(1)(ii) or 3(c)(2)(i) above, the Trust and the Company shall promptly
prepare, subject to Section 7(b) hereof, as soon as possible a post-effective
amendment to any Shelf Registration Statement or an amendment or supplement to
the related Prospectus or file any other required document so that, as
thereafter delivered to purchasers of the Securities included therein, the
Prospectus will not include an untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. If the Trust or
the Company notifies the Electing Holders in accordance with Section 3(c)(3)
above to suspend use of the prospectus until the requisite changes to the
Prospectus have been made, then the Electing Holders shall suspend the use of
the Prospectus until the requisite changes to the Prospectus have been made, and
the period of effectiveness of the Shelf Registration Statement provided for in

Holders, the Convertible Junior Subordinated Debentures, registered under such
Shelf Registration Statement, and provide the applicable Trustee with
certificates for such Securities, in a form eligible for deposit with The
Depository Trust Company.

         (11)  The Trust and the Company shall comply with all applicable
rules and regulations of the Commission and shall make generally available to
their securityholders (or otherwise provide in accordance with Section 11(a) of
the Securities Act) an earnings statement satisfying the provisions of Section
11(a) of the Securities Act, no later than 45 days after the end of a 12-month
period (or 90 days, if such period is a fiscal year) beginning with the first
month of the Company's first quarter commencing after the effective date of the
Registration Statement, which statement shall cover such 12-month period.

         (l2)  The Trust and the Company shall cause the Indenture, the
Declaration and the Guarantee to be qualified under the Trust Indenture Act in a
timely manner and containing such changes, if any, as shall be necessary for
such qualification. In the event that such qualification would require the
appointment of a new trustee under the Indenture, the Company shall appoint a
new trustee thereunder pursuant to the applicable provisions of the Indenture.

         (13)  The Trust and the Company may require each Electing Holder to
furnish to the Trust and the Company such information regarding the Electing
Holder and the distribution of such Securities as the Trust and the Company may
from time to time reasonably require for inclusion in such Shelf Registration
Statement, and the Trust and the Company may exclude from such registration the
Securities of any Electing Holder that

                                       8

incorporate in a Prospectus supplement or post-effective amendment to a Shelf
Registration Statement, such information as the Managing Underwriters reasonably
agree should be included therein and to which the Trust and the Company do not

supplement or post-effective amendment as soon as practicable after they are

obligated to arrange for more than one underwritten offering during the Shelf
Registration Period as set forth in Section 6 hereof .

         (15)  The Trust and the Company shall enter into such customary
agreements (including underwriting agreements in customary form) to take all
other appropriate actions in order to expedite or facilitate the registration or
the disposition of the Securities, and in connection therewith, if an
underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures substantially identical to those set

Managing Underwriters, if any) with respect to all parties to be indemnified
pursuant to Section 5.

         (16)  The Trust and the Company shall (i) make reasonably available for
inspection by the Electing Holders, any underwriter participating in any

Company. The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of
this Section 3(p) shall be performed at (A) with respect to clauses (ii) and (v)

                                       10
<PAGE>

Rules and By-Laws, including, without limitation, by (A) if such Rules or By-
Laws, including Schedule E thereto, shall so require, engaging a "qualified
independent underwriter" (as defined in such Schedule) to participate in the
preparation of the Shelf Registration Statement relating to such Securities, to
exercise usual standards of due diligence in respect thereto, (B) indemnifying
any such qualified independent underwriter to the extent of the indemnification
of underwriters provided in Section 5 hereof and (C) providing such information
to such broker-dealer as may be required in order for such broker-dealer to
comply with the requirements of the Rules of Fair Practice of the NASD.

         (19)  The Company will use its best efforts to (a) if the Securities
have been rated prior to the initial sale of such Securities, confirm such
ratings will apply to the Securities covered by the Shelf Registration
Statement, or (b) if the Securities were not previously rated, cause the

Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Securities Act, the Exchange Act or other Federal or state statutory
law or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Shelf Registration Statement as originally filed or in any
amendment thereof, or in any preliminary prospectus or Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are 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, and
agree to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability

                                       11

or action; provided, however, that (i) the Company and the Trust will not be
liable in any case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf any
such Electing Holder specifically for inclusion therein and, provided, further,
that with respect to any untrue statement or alleged untrue statement in or
omission or alleged omission from any preliminary prospectus, the indemnity
agreement contained in this subsection (a) shall not inure to the benefit of any
Electing Holder or person who controls any such Electing Holder from whom the
person asserting any such losses, claims, damages or liabilities purchased the
Securities concerned, to the extent that a prospectus relating to such
Securities was required to be delivered by such Electing Holder under the Act in
connection with such purchase and any such loss, claim, damage or liability of
such Electing Holder results from the fact that there was not sent or given to
such person, at or prior to the written confirmation of the sale of such
Securities to such person, a copy of the Prospectus if the Company has
previously furnished such quantity of copies thereof to such Electing Holder.
This indemnity agreement will be in addition to any liability which the Company
or the Trust may otherwise have. The Trust and the Company, jointly and
severally, also agree to indemnify or contribute to Losses (as defined below)
of, as provided in Section 5(d), any underwriters of Securities registered under
the Shelf Registration Statement, their officers, directors, employees and
agents and each person who controls such underwriters on substantially the same
basis as that of the indemnification of the Electing Holders provided in this
Section 5(a) and shall, if requested by any Electing Holder, enter into an
underwriting agreement reflecting such agreement, as provided in Section 3(o)
and Section 6 hereof.

         (b)  Each Electing Holder, severally and not jointly, agrees as a
consequence of the inclusion of any of such Holder's Registrable Securities in
such Shelf Registration Statement, and each underwriter executing an
underwriting agreement, if any, which facilitates the disposition of Registrable
Securities shall agree, as a consequence of facilitating such disposition of
Registrable Securities, severally and not jointly, to indemnify and hold
harmless (i) the Trust and the Company, (ii) each of the directors of the
Company, (iii) each of its officers and any Administrative Trustee who signs
such Shelf Registration Statement and (iv) each person who controls the Trust or
the Company within the meaning of either the Securities Act or the Exchange Act
to the same extent as the foregoing indemnity from the Trust and the Company,
but only with reference to written information relating to such Electing Holder
or underwriter executing an underwriting agreement furnished to the Company by
or on behalf of such Electing Holder or underwriter executing an underwriting
agreement specifically for inclusion in the documents referred to in the
foregoing indemnity; and shall reimburse, as incurred, the Company and the Trust
for any legal or other expenses reasonably incurred by the Company or the Trust
or any such controlling person in connection with investigating or defending any
loss, claim, damage, liability or action in respect thereof.  This indemnity
agreement will be in addition to any

                                       12
<PAGE>

liability which any such Electing Holder or underwriter executing an
underwriting agreement may otherwise have.

         (c)  Promptly after receipt by an indemnified party under this Section
5 of notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under this Section 5,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not relieve the indemnifying party from
any liability it may have to any indemnified party otherwise than under
paragraph (a) or (b) above, except to the extent such failure prejudices the
indemnified person. In case any such action is brought against any indemnified
party and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party (who shall not, except with the consent of such indemnified party, be
counsel to the indemnifying party), and after notice from the indemnifying party
to such indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action, and does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 5 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall have a joint and several
obligation to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending same) (collectively "Losses") to which such
indemnified party may be subject in such proportion as is appropriate to reflect
the relative benefits received by such indemnifying party, on the one hand, and
such indemnified party, on the other hand, from the Initial Placement and the
Shelf Registration Statement which resulted in such Losses; provided, however,
that in no case shall the Purchasers or any subsequent Holder of any Securities
be responsible, in the aggregate, for any amount in excess of the amount by
which the net proceeds received by such Holders from the sale of the Securities
pursuant to the Registration Statement exceeds the amount of damages which such
Holders have otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. If the allocation provided by
the immediately

                                       13
<PAGE>

preceding sentence is unavailable for any reason, the indemnifying party and the
indemnified party shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of such
indemnifying party, on the one hand, and such indemnified party, on the other
hand, in connection with the statements or omissions which resulted in such
Losses as well as any other relevant equitable considerations. Relative fault
shall be determined by reference to whether any alleged untrue statement or
omission relates to information provided by the indemnifying party, on the one
hand, or by the indemnified party, on the other hand. The parties agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this
subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any action or claim which is the subject of this subsection (d). For purposes of
this Section 5, each person who controls a Holder within the meaning of either
the Securities Act or the Exchange Act shall have the same rights to
contribution as such Holder, and each person who controls the Company or the
Trust within the meaning of either the Securities Act or the Exchange Act, each
officer of the Company who shall have signed the Shelf Registration Statement
and each director of the Company shall have the same rights to contribution as
the Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

         (e)  The provisions of this Section 5 will remain in full force and
effect, regardless of any investigation made by or on behalf of any Holder or
the Company or the Trust or any of the officers, directors, employees, agents or
controlling persons referred to in Section 5 hereof, and will survive the sale
by a Holder of Securities covered by the Shelf Registration Statement. The
obligations of the Trust and the Company under this Section shall be in addition
to any liability which the Trust and the Company may otherwise have.

     6.   Underwritten Offering. The Holders of Securities covered by the Shelf
Registration Statement who desire to do so may sell such Securities in an
underwritten offering. In any such underwritten offering, the investment banker
or bankers and manager or managers that will administer the offering will be
selected by, and the underwriting arrangements with respect thereto will be
approved by, the Holders of a majority of the Securities to be included in such
offering; provided, however, that (i) such investment bankers and managers and
underwriting arrangements must be reasonably satisfactory to the Company and the
Trust and (ii) the Company shall not be obligated to arrange for more than one
underwritten offering during the Shelf Registration Period. No Holder may
participate in any underwritten offering contemplated hereby unless such Holder
(a) agrees to sell such

                                       14
<PAGE>

Holder's Securities in accordance with any approved underwriting arrangements,
(b) completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such approved underwriting arrangements, (c) at
least 30% of the outstanding Securities are included in such underwritten
offering, and (d) if such Holder is not then an Electing Holder, such Holder
provides the Company and the Trust with such information as they shall
reasonably request in order to enable the Company and the Trust to comply with
the applicable requirements of the Securities Act in connection with offers and
sales by such Holder as a selling securityholder in the underwritten offering
within a reasonable amount of time before such underwritten offering. The
Holders participating in any underwritten offering shall be responsible for any
expenses customarily borne by selling securityholders, including underwriting
discounts and commissions and fees and expenses of counsel to the selling
securityholders.

     7.  Special Interest and Special Distributions Under Certain Circumstances.
If (i) within 150 days of the First Closing Date the Shelf Registration
Statement has not been declared effective by the Commission, or (ii) in the
event that a Shelf Registration Statement is declared effective by the
Commission, the Company or the Trust fails to keep such Shelf Registration
Statement continuously effective and usable (except as permitted in paragraph
(b) of this Section 7) prior to the end of the Shelf Registration Period (each
such event referred to in clauses (i) and (ii) a "Registration Default"), then
additional interest ("Special Interest") will accrue on the Convertible Junior
Subordinated Debentures (including in respect of amounts accruing during any
Deferral Period), and corresponding additional distributions (the "Special
Distributions") will accrue on the TIDES and the Common Securities, in each case
from and including the day following such Registration Default to but excluding
the day on which such Registration Default has been cured or has been deemed to
have been cured.  Subject to the deferral of interest provisions of the
Convertible Junior Subordinated Debentures and the deferral of distributions
provisions of the TIDES, Special Interest and Special Distributions will be paid
in cash quarterly in arrears on March 15, June 15, September 15 and December 15
commencing with the first such date following the applicable Registration
Default and will accrue at a rate such that the interest rate or distribution
rate, as the case may be, will be increased 0.50% per annum of the principal
amount or liquidation amount, as applicable.  Following the cure of a
Registration Default, Special Interest and Special Distributions will cease to
accrue with respect to such Registration Default.

         (3)  A Registration Default referred to in Section 7(a)(ii) shall be
deemed not to have occurred and be continuing in relation to the Shelf
Registration Statement or the related Prospectus if such Registration Default
has occurred solely as a result of (x) the filing of a post-effective amendment
to such Shelf Registration Statement to incorporate annual audited financial
information with respect to the Company where such post-effective amendment is
not yet effective and needs to be declared effective to permit Holders to use
the related Prospectus or (y) the occurrence of other material events or
developments with

                                       15
<PAGE>

respect to the Trust or the Company that would need to be described in such
Registration Statement or the related Prospectus and either (i) the Company
shall have determined in good faith that such disclosure is not in the best
interests of the Company and its stockholders or (ii) the Trust and the Company
are proceeding promptly and in good faith to amend or supplement such
Registration Statement and related Prospectus to describe such events; provided,
however, that in any case, if such Registration Default occurs for a continuous
period in excess of 45 days, Special Interest and Special Distributions shall be
payable in accordance with the above paragraph from the first day of such 45-day
period until the date on which such Registration Default is cured.


     8.  Rules 144 and 144A.  The Company shall use its best efforts to file the
reports required to be filed by it under the Securities Act and the Exchange Act
in a timely manner and, if at any time the Company is not required to file such
reports, it will, within a reasonable period of time, upon written request of
any Holder of Securities, make publicly available other information so long as
necessary to permit sales of their securities pursuant to Rules 144 and 144A.
The Company covenants that it will take such further action as any Holder of
Securities may reasonably request, all to the extent required from time to time
to enable such Holder to sell Securities without registration under the
Securities Act within the limitation of the exemptions provided by Rules 144 and
144A (including the requirements of Rule 144A(d)(4)).  The Company will provide
a copy of this Agreement to prospective purchasers of Securities identified to
the Company by any Purchaser upon request.  Upon the request of any Holder of
Securities, the Company shall deliver to such Holder a written statement as to
whether it has complied with such requirements.  Notwithstanding the foregoing,
nothing in this Section 8 shall be deemed to require the Company to register any
of its securities pursuant to the Exchange Act.

     9.   Miscellaneous.

         (3)  No Inconsistent Agreements. The Trust and the Company have not, as
of the date hereof, entered into, nor shall they on or after the date hereof,
enter into, any agreement with respect to their securities or otherwise that is
inconsistent with the rights granted to the Holders herein or otherwise
conflicts with the provisions hereof.

         (4)  Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Trust and the Company have
obtained the written consent of the Credit Suisse First Boston Corporation.

                                      16
<PAGE>

         (5)  Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telex, telecopier, or air courier guaranteeing overnight delivery:

         (1)  if to a Holder, at the most current address given by such Holder
to the Company in accordance with the provisions of this Section 7(c), which
address initially is, with respect to each Holder, the address of such Holder
maintained by the Registrar under the Indenture;

         (2)   if to the Purchasers, initially at the address set forth in the
Purchase Agreement; and

         (3)   if to the Trust or the Company, initially at its address set
forth in the Purchase Agreement.

     All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; three business
days after being deposited in the mail, postage prepaid, if mailed; when receipt
is acknowledged by recipient's facsimile machine operator, if sent by facsimile
transmission; and on the day delivered, if sent by overnight air courier
guaranteeing next day delivery.

     The Purchaser or the Trust and the Company by notice to the other may
designate additional or different addresses for subsequent notices or
communications.

         (6)  Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties and the
Holders, including, without the need for an express assignment or any consent by
the Trust or the Company thereto, subsequent Holders of Securities. The Trust
and the Company hereby agree to extend the benefits of this Agreement to any
Holder of Securities and any such Holder may specifically enforce the provisions
of this Agreement as if an original party hereto.

         (7)  Counterparts. This agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (8)  Headings. The headings in this agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (9)  Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
PRINCIPLES THEREOF REGARDING CONFLICTS OF LAWS.

                                       17
<PAGE>

         (10)  Severability. In the event that any one of more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties
shall be enforceable to the fullest extent permitted by law.

         (11)  Third Party Beneficiaries. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Trust, on the one hand, and the Purchasers, on the other hand, and the Holders
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect their rights or the
rights of Holders hereunder.

         (12)  Securities Held by the Company. Whenever the consent or approval
of Holders of a specified percentage of principal amount of Securities is
required hereunder, Securities held by the Company or its affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.
