                              ABOUT THIS PROSPECTUS

     This prospectus is part of a registration statement that we filed with the
SEC utilizing a "shelf" registration process. Under this shelf process, we may,
from time to time, sell any combination of the securities described in this
prospectus in one or more offerings up to a total dollar amount of $250,000,000.

     This prospectus provides you with a general description of the securities
we may offer. Each time we sell securities, we will provide a prospectus
supplement that will contain specific information about the terms of that
offering. The prospectus supplement may also add, update or change information
contained in this prospectus. You should read both this prospectus and any
prospectus supplement together with additional information described under the
heading below "Where You Can Find More Information."

     You should rely only on the information or representations incorporated by
reference or provided in this prospectus and in the accompanying prospectus
supplement. We have not authorized anyone to provide you with different
information. You may obtain copies of the registration statement, or of any
document which we have filed as an exhibit to the registration statement or to
any other SEC filing, either from the SEC or from our corporate secretary as
described below. We are not making an offer of these securities in any state
where the offer is not permitted. You should not assume that the information in
this prospectus or in the accompanying prospectus supplement is accurate as of
any date other than the dates printed on the front of each such document.

     Unless otherwise indicated or otherwise required by the context in which
the term occurs, all references in this prospectus or a supplement to "we,"
"our," "us," "company" or similar terms refer to Unit Corporation together with
its subsidiaries.

                           FORWARD-LOOKING STATEMENTS

     This prospectus, including the information we incorporate by reference,
information included in, or incorporated by reference from, future filings by us
with the SEC, as well as information contained in written material, press
releases and oral statements issued by or on behalf of us, contain, or may
contain, certain statements that may be deemed to be "forward-looking
statements" within the meaning of federal securities laws. All statements, other
than statements of historical facts, included or incorporated by reference in
this prospectus, which address activities, events or developments which we
expect or anticipate will or may occur in the future are forward-looking
statements. The words "believes," "intends," "expects," "anticipates,"
"projects," "estimates," "predicts" and similar expressions are also intended to
identify forward-looking statements.

     These forward-looking statements include, among others, such things as:

     .   the amount and nature of our future capital expenditures;

     .   wells to be drilled or reworked;

     .   prices for oil and gas;

     .   demand for oil and gas

     .   exploitation and exploration prospects;

     .   estimates of proved oil and gas reserves;

     .   reserve potential;

     .   development and infill drilling potential;

     .   drilling prospects;

     .   expansion and other development trends of the oil and gas industry;

     .   business strategy;

     .   production of oil and gas reserves;

     .   expansion and growth of our business and operations; and

     .   drilling rig utilization and drilling rig rates.

     These statements are based on certain assumptions and analyses made by us
in light of our experience and our perception of historical trends, current
conditions and expected future developments as well as other factors we believe
are appropriate in the

                                      -1-


circumstances. However, whether actual results and developments will conform to
our expectations and predictions is subject to a number of risks and
uncertainties which could cause actual results to differ materially from our
expectations, including:

     .   the risk factors discussed in this prospectus and in the documents we
         incorporate by reference;

     .   general economic, market or business conditions;

     .   the nature or lack of business opportunities that may be presented to
         and pursued by us;

     .   demand for our land drilling services;

     .   changes in laws or regulations; and

     .   other factors, most of which are beyond our control.

     We describe these risks and uncertainties in greater detail under the
caption "Risk Factors" below and in our recent Forms 10-Q and 10-K filed with
the SEC. See "Where You Can Find More Information" and "Documents Incorporated
by Reference."

     You should not place undue reliance on any these forward-looking
statements. We disclaim any current intention to update forward-looking
information and to release publicly the results of any future revisions we may
make to forward-looking statements to reflect events or circumstances after the
date of this prospectus or the accompanying prospectus supplement to reflect the
occurrence of unanticipated events.

                                  RISK FACTORS

     You should carefully consider the following risk factors, in addition to
the other information set forth in this prospectus, before purchasing any of our
securities. Each of these risk factors could adversely affect our business,
operating results and financial condition, as well as adversely affect the value
of an investment in any of our securities. This investment involves a high
degree of risk.

Oil and gas prices are volatile, and low prices have negatively affected our
financial results and could do so in the future.

     Our revenues, operating results, cash flow and future rate of growth depend
substantially upon prevailing prices for oil and gas. Historically, oil and gas
prices and markets have been volatile, and they are likely to continue to be
volatile in the future. Any decline in prices in the future would have a
negative impact on our future financial results. Because our reserves are
predominantly gas, changes in gas prices may have a particularly large impact on
our financial results.

     Prices for oil and gas are subject to wide fluctuations in response to
relatively minor changes in the supply of and demand for oil and gas, market
uncertainty and a variety of additional factors that are beyond our control.
These factors include:

     .   political conditions in oil producing regions, including the Middle
         East and South America;

     .   the ability of the members of the Organization of Petroleum Exporting
         Countries to agree to and maintain oil price and production controls;

     .   the price of foreign imports;

     .   actions of governmental authorities;

     .   the domestic and foreign supply of oil and gas;

     .   the level of consumer demand;

     .   weather conditions;

     .   domestic and foreign government regulations;

     .   the price, availability and acceptance of alternative fuels; and

     .   overall economic conditions.

     These factors and the volatile nature of the energy markets make it
impossible to predict with any certainty the future prices of oil and gas.

                                      -2-


Our contract drilling operations depend on levels of activity in the oil and gas
exploration and production industry.

     Our contract drilling operations depend on the level of activity in oil and
gas exploration and production in our operating markets. Both short-term and
long-term trends in oil and gas prices affect the level of that activity.
Because oil and gas prices are volatile, the level of exploration and production
activity can also be volatile. We expect that in the near term our customers
will continue a cautious approach to exploration and development spending. Any
decrease from current oil and gas prices would depress the level of exploration
and production activity. This, in turn, would likely result in a decline in the
demand for our drilling services and would have an adverse effect on our
contract drilling revenues, cash flows and profitability. As a result, the
future demand for our drilling services is uncertain.

The industries in which we operate are highly competitive, and many of our
competitors have greater resources than we do. In particular, the contract
drilling industry has intense price competition and excess rig supply.

     The drilling industry in which we operate is very competitive. Most
drilling contracts are awarded on the basis of competitive bids, which results
in intense price competition. In the markets in which we operate, the number of
rigs available for use exceeds the demand for rigs, which increases this price
competition. Several of our competitors in the contract drilling industry have
greater financial and human resources than we do. These resources may enable
them to better withstand periods of low rig utilization, to compete more
effectively on the basis of price and technology, to build new rigs or acquire
existing rigs and to provide rigs more quickly than we do in periods of high rig
utilization.

     The oil and gas industry is also highly competitive. We compete in the
areas of property acquisitions and oil and gas exploration, development,
production and marketing with major oil companies, other independent oil and
natural gas concerns and individual producers and operators. In addition, we
must compete with major and independent oil and natural gas concerns in
recruiting and retaining qualified employees. Many of our competitors in the oil
and gas industry have substantially greater financial and other resources than
we do.

Shortages of experienced personnel for our contract drilling operations could
limit our ability to meet the demand for our services.

     In recent years, the number of oil and gas drilling rigs in operation has
declined substantially. As a result, a large number of experienced personnel in
this industry have moved to other industries or fields. If the demand for
contract drilling services should increase significantly, we and most other
drilling contractors may have difficulties in employing enough qualified and
experienced personnel to be able to meet that demand completely.

Our operations have significant capital requirements, and our debt could have
important consequences to you.

     We have experienced and expect to continue to experience substantial
working capital needs due to our growth in drilling operations and our active
exploration, development and exploitation programs. At December 31, 2002, our
long-term debt outstanding was $35.9 million. As of December 31, 2002, the
amount available for borrowing under our credit facility was $40 million, of
which $30.5 million was outstanding. Our level of indebtedness, the cash flow
needed to satisfy our indebtedness and the covenants governing our indebtedness
could:

     .   limit funds available for financing capital expenditures, our drilling
         program or other activities or cause us to curtail these activities;

     .   limit our flexibility in planning for, or reacting to changes in, our
         business;

     .   place us at a competitive disadvantage to some of our competitors that
         have less debt than we do;

     .   make us more vulnerable during periods of low oil and gas prices or in
         the event of a downturn in our business; and

     .   prevent us from obtaining additional financing on acceptable terms or
         limit amounts available under our existing or any future credit
         facilities.

     Our ability to meet our debt obligations will depend on our future
performance. In addition, lower oil and gas prices could result in future
reductions in the amount available for borrowing under our loan agreement,
reducing our liquidity and even triggering mandatory loan repayments.

Our future performance depends upon our ability to find or acquire additional
oil and gas reserves that are economically recoverable.

     In general, production from oil and natural gas properties declines as
reserves are depleted, with the rate of decline depending on reservoir
characteristics. Unless we successfully replace the reserves that we produce,
our reserves will decline, resulting eventually in a decrease in oil and gas
production and lower revenues and cash flow from operations. Historically, we
have succeeded
                                      -3-


in increasing reserves after taking production into account through
exploitation, development, exploration and acquisitions. We have conducted such
activities on our existing oil and gas properties as well as on newly acquired
properties. We may not be able to continue to replace reserves from such
activities at acceptable costs. Low prices of oil and gas may further limit the
kinds of reserves that can economically be developed. Lower prices also decrease
our cash flow and may cause us to decrease capital expenditures.

     We are continually identifying and evaluating opportunities to acquire oil
and gas properties, including acquisitions that would be significantly larger
than those consummated to date by us. We cannot assure you that we will
successfully consummate any acquisition, that we will be able to acquire
producing oil and gas properties that contain economically recoverable reserves
or that any acquisition will be profitably integrated into our operations.

Our exploration and production operations involve a high degree of business
and financial risk which could adversely affect us.

     Exploitation, development and exploration involve numerous risks that may
result in dry holes, the failure to produce oil and gas in commercial quantities
and the inability to fully produce discovered reserves. The cost of drilling,
completing and operating wells is substantial and uncertain. Numerous factors
beyond our control may cause the curtailment, delay or cancellation of drilling
operations, including:

     .   unexpected drilling conditions;

     .   pressure or irregularities in formations;

     .   equipment failures or accidents;

     .   adverse weather conditions;

     .   compliance with governmental requirements; and

     .   shortages or delays in the availability of drilling rigs or delivery
         crews and the delivery of equipment.

     Exploratory drilling is a speculative activity. Although we may disclose
our overall drilling success rate, those rates may decline. Although we may
discuss drilling prospects that we have identified or budgeted for, we may
ultimately not lease or drill these prospects within the expected time frame, or
at all. Lack of drilling success will have an adverse effect on our future
results of operations and financial condition.

Our hedging arrangements might limit the benefit of increases in natural gas
prices.

     In order to reduce our exposure to short-term fluctuations in the price of
oil and gas, we sometimes enter into hedging arrangements. Our hedging
arrangements apply to only a portion of our production and provide only partial
price protection against declines in oil and gas prices. These hedging
arrangements may expose us to risk of financial loss and limit the benefit to us
of increases in prices.

Estimates of our reserves are uncertain and may prove to be inaccurate, and oil
and gas price declines may lead to an impairment of our oil and gas assets.

     There are numerous uncertainties inherent in estimating quantities of
proved reserves and their values, including many factors beyond our control. The
reserve data included or incorporated by reference in this prospectus or any
accompanying prospectus represent only estimates. Reservoir engineering is a
subjective and inexact process of estimating underground accumulations of oil
and gas that cannot be measured in an exact manner. Estimates of economically
recoverable oil and gas reserves depend on a number of variable factors,
including historical production from the area compared with production from
other producing areas, and assumptions concerning:

     .   the effects of regulations by governmental agencies;

     .   future oil and gas prices;

     .   future operating costs;

     .   severance and excise taxes;

     .   development costs; and

     .   workover and remedial costs.

                                      -4-


     Some or all of these assumptions may vary considerably from actual results.
For these reasons, estimates of the economically recoverable quantities of oil
and gas attributable to any particular group of properties, classifications of
those reserves based on risk of recovery, and estimates of the future net cash
flows from reserves prepared by different engineers or by the same engineers but
at different times may vary substantially. Accordingly, reserve estimates may be
subject to downward or upward adjustment. Actual production, revenues and
expenditures with respect to our reserves will likely vary from estimates, and
those variances may be material.

     The information regarding discounted future net cash flows included in or
incorporated by reference in this prospectus should not be considered as the
current market value of the estimated oil and gas reserves attributable to our
properties. As required by the SEC, the estimated discounted future net cash
flows from proved reserves are based on prices and costs as of the date of the
estimate, while actual future prices and costs may be materially higher or
lower. Actual future net cash flows also will be affected by the following
factors:

     .   the amount and timing of actual production;

     .   supply and demand for oil and gas;

     .   increases or decreases in consumption; and

     .   changes in governmental regulations or taxation.

     In addition, the 10% discount factor, which is required by the SEC to be
used in calculating discounted future net cash flows for reporting purposes, is
not necessarily the most appropriate discount factor based on interest rates in
effect from time to time and risks associated with our operations or the oil and
gas industry in general.

     We periodically review the carrying value of our oil and gas properties
under the full cost accounting rules of the SEC. Under these rules, capitalized
costs of proved oil and gas properties may not exceed the present value of
estimated future net revenues from proved reserves, discounted at 10%.
Application of the ceiling test generally requires pricing future revenue at the
unescalated prices in effect as of the end of each fiscal quarter and requires a
write-down for accounting purposes if the ceiling is exceeded, even if prices
were depressed for only a short period of time. We may be required to write down
the carrying value of our oil and gas properties when oil and gas prices are
depressed or unusually volatile. If a write-down is required, it would result in
a charge to earnings, but would not impact cash flow from operating activities.
Once incurred, a write-down of oil and gas properties is not reversible at a
later date.

Our operations present inherent risks of loss that, if not insured or
indemnified against, could adversely affect our results of operations.

     Our drilling operations are subject to many hazards inherent in the
drilling industry, including blowouts, cratering, explosions, fires, loss of
well control, loss of hole, damaged or lost drilling equipment and damage or
loss from inclement weather. Our exploration and production operations are
subject to these and similar risks. Any of these events could result in personal
injury or death, damage to or destruction of equipment and facilities,
suspension of operations, environmental damage and damage to the property of
others. Generally, drilling contracts provide for the division of
responsibilities between a drilling company and its customer, and we seek to
obtain indemnification from our drilling customers by contract for some of these
risks. To the extent that we are unable to transfer these risks to drilling
customers by contract or indemnification agreements, we seek protection through
insurance which our management considers to be adequate. However, we cannot
assure you that our insurance or indemnification agreements will adequately
protect us against liability from all of the consequences of the hazards
described above. The occurrence of an event not fully insured or indemnified
against, or the failure of a customer to meet its indemnification obligations,
could result in substantial losses. In addition, we cannot assure you that
insurance will be available to cover any or all of these risks. Even if
available, the insurance might not be adequate to cover all of our losses, or we
might decide against obtaining that insurance because of high premiums or other
costs.

     In addition, we are not the operator of some of our wells. As a result, our
operating risks for those wells and our ability to influence the operations for
those wells are less subject to our control. Operators of those wells may act in
ways that are not in our best interests.

Governmental and environmental regulations could adversely affect our business.

     Our business is subject to federal, state and local laws and regulations on
taxation, the exploration for and development, production and marketing of oil
and gas and safety matters. Many laws and regulations require drilling permits
and govern the spacing of wells, rates of production, prevention of waste,
unitization and pooling of properties and other matters. These laws and
regulations have increased the costs of planning, designing, drilling,
installing, operating and abandoning our oil and gas wells and other facilities.
In addition, these laws and regulations, and any others that are passed by the
jurisdictions where we have production, could limit the total number of wells
drilled or the allowable production from successful wells, which could limit our
revenues.
                                      -5-


     Our operations are also subject to complex environmental laws and
regulations adopted by the various jurisdictions where we operate. We could
incur liability to governments or third parties for any unlawful discharge of
oil, gas or other pollutants into the air, soil or water, including
responsibility for remedial costs. We could potentially discharge these
materials into the environment in any number of ways including the following:

     .   from a well or drilling equipment at a drill site;

     .   from gathering systems, pipelines, transportation facilities and
         storage tanks;

     .   damage to oil and natural gas wells resulting from accidents during
         normal operations; and

     .   blowouts, cratering and explosions.

     Because the requirements imposed by laws and regulations are frequently
changed, we cannot assure you that laws and regulations enacted in the future,
including changes to existing laws and regulations, will not adversely affect
our business. In addition, because we acquire interests in properties that have
been operated in the past by others, we may be liable for environmental damage
caused by the former operators.

Our stockholders' rights plan and provisions of Delaware law and our by-laws and
charter could discourage change in control transactions and prevent stockholders
from receiving a premium on their investment.

     Our by-laws provide for a classified board of directors with staggered
terms and authorize the board of directors to set the terms of preferred stock.
In addition, our charter and Delaware law contain provisions that impose
restrictions on business combinations with interested parties. We have also
adopted a stockholders' rights plan. Because of our stockholders' rights plan
and these provisions of our by-laws, charter and Delaware law, persons
considering unsolicited tender offers or other unilateral takeover proposals may
be more likely to negotiate with our board of directors rather than pursue
non-negotiated takeover attempts. As a result, these provisions may make it more
difficult for our stockholders to benefit from transactions that are opposed by
an incumbent board of directors.

                         DESCRIPTION OF DEBT SECURITIES

     The following description of the terms of the debt securities, which may
consist of senior notes and debentures and subordinated notes and debentures,
sets forth certain general terms and provisions of the debt securities to which
any prospectus supplement may relate. The particular terms of the debt
securities offered by any prospectus supplement and the extent, if any, to which
such general provisions may apply to the debt securities being offered will be
described in the prospectus supplement relating to such debt securities. You
will need to review both the prospectus supplement and the following description
for a description of the terms of a particular issue of our debt securities.

     The debt securities will be general obligations and may be subordinated to
our senior indebtedness (as discussed below) to the extent set forth in the
applicable prospectus supplement. See "Description of Debt
Securities--Subordination" below. Debt securities will be issued under an
indenture to be entered into between us and an indenture trustee to be selected
by us and named in a prospectus supplement. A copy of the form of indenture has
been filed as an exhibit to the registration statement. This discussion of
certain provisions of the indenture is a summary only and is not a complete
description of the terms and provisions of the indenture. This discussion is
completely qualified by reference to the actual terms of the indenture. Whenever
defined terms are used but not defined in this prospectus, those terms have the
meanings specified in the indenture.

General

     The indenture does not limit the aggregate principal amount of debt
securities that we may issue. We may issue the debt securities from time to time
in one or more series. The indenture does not limit the amount of other
unsecured indebtedness or securities which we may issue. Unless otherwise
indicated in the applicable prospectus supplement, the debt securities will not
benefit from any covenant or other provision that would afford holders of debt
securities special protection in the event of a highly leveraged transaction
involving us. The applicable prospectus supplement will contain the following
terms of the debt securities of the series for which the prospectus supplement
is being delivered:

     .   the title;

     .   any limit on the aggregate principal amount of the debt securities;

     .   the date or dates on which the principal and premium, if any, are
         payable;

     .   the rate or rates (which may be fixed or variable), or the method of
         determining the rate or rates, at which the debt securities will bear
         interest, the date or dates from when interest will accrue, the dates
         when interest will be payable or the method by which the dates will be
         determined, the record dates for determining who the interest will be
         paid to, and the basis upon which interest will be calculated if other
         than that of a 360-day year of twelve 30-day months;

                                      -7-


     .   when principal, premium, if any, and interest will be paid;

     .   the terms and conditions on which the debt securities may be redeemed;

     .   our obligation, if any, to redeem, purchase, or repay the debt
         securities because of any sinking fund or analogous provisions or at
         the option of a holder of the debt securities and the price or prices
         at which, the period or periods within which, and the terms on which
         the debt securities of the series will be redeemed, purchased, or
         repaid, in whole or in part;

     .   the terms, if any, on which the debt securities may be convertible into
         or exchanged for our securities or any other issuer or obligor and the
         terms and conditions upon which such conversion or exchange will be
         effected, including the initial conversion or exchange price or rate,
         the conversion or exchange period and any other provision;

     .   the denominations in which the debt securities will be issuable;

     .   if the amount of principal, premium, if any, or interest with respect
         to the debt securities may be determined with reference to an index or
         pursuant to a formula, the manner in which such amounts will be
         determined;

     .   if the principal amount payable at the stated maturity of the debt
         securities will not be determinable as of any one or more dates prior
         to the stated maturity, the amount that will be deemed to be such
         principal amount as of any such date for any purpose, including the
         principal amount that will be due and payable upon any maturity other
         than the stated maturity or that will be deemed to be outstanding as of
         any such date (or, in such case, the manner in which such deemed
         principal amount is to be determined), and if necessary, the manner of
         determining the equivalent principal amount in United States currency;

     .   any changes or additions to the provisions of the indenture dealing
         with defeasance, including the addition of additional covenants that
         may be subject to our covenant defeasance option;

     .   if other than United States dollars, the coin or currency or currencies
         or units of two or more currencies in which payment of the principal,
         premium, if any, and interest with respect to debt securities shall be
         payable;

     .   if other than the principal amount of debt securities, the portion of
         the principal amount of debt securities which will be payable upon
         declaration of acceleration or provable in bankruptcy;

     .   the terms, if any, of the transfer, mortgage, pledge or assignment as
         security for the debt securities of any properties, assets, moneys,
         proceeds, securities or other collateral, including whether certain
         provisions of the Trust Indenture Act are applicable and any
         corresponding changes to provisions of the indenture as currently in
         effect;

     .   any addition to or change in the events of default with respect to the
         debt securities and any change in the right of the trustee or the
         holders to declare the principal of and interest on such debt
         securities due and payable;

     .   whether the debt securities will be issued in whole or in part in
         global form, the terms and conditions on which any global security may
         be exchanged in whole or in part for other individual debt securities
         in definitive registered form and the depositary for any such global
         security;

     .   any trustees, authenticating or paying agents, transfer agents or
         registrars;

     .   the applicability of, and any addition to or change in the covenants
         and definitions currently set forth in the indenture or in the terms
         relating to permitted consolidations, mergers, or sales of assets,
         including conditioning any merger, conveyance, transfer or lease
         permitted by the indenture upon the satisfaction of an indebtedness
         coverage standard by us;

     .   the terms, if any, of any guarantee of the payment of principal of, and
         premium, if any, and interest on, debt securities and any corresponding
         changes to the provisions of the indenture as currently in effect;

     .   the subordination, if any, of the debt securities and any changes or
         additions to the provisions of the indenture relating to subordination;

     .   if debt securities do not bear interest, the dates for certain required
         reports to the trustee;

     .   any other terms of the debt securities not prohibited by the indenture;
         and

     .   any material United States federal income tax consequences or other
         special considerations applicable to the series of debt securities
         offered.
                                       -8-


     Senior debt securities may be issued as original issue discount senior debt
securities, which bear no interest or interest at a rate which at the time of
issuance is below market rates, to be sold at a substantial discount below their
stated principal amount due at the stated maturity of the senior debt
securities. There may be no periodic payments of interest on original issue
discount securities. In the event of an acceleration of the maturity of any
original issue discount security, the amount payable to the holder of the
original issue discount security upon acceleration will be determined in
accordance with the prospectus supplement, the terms of the security and the
indenture, but will be an amount less than the amount payable at the maturity of
the principal of the original issue discount security.

     If the senior debt securities are issued with "original issue discount"
within the meaning of the Internal Revenue Code of 1986, as amended, then a
holder of those senior debt securities will be required under the Internal
Revenue Code to include original issue discount in ordinary income for federal
income tax purposes as it accrues, in accordance with a constant interest method
that takes into account the compounding of interest, in advance of receipt of
cash attributable to that income. Generally, the total amount of original issue
discount on a senior debt security will be the excess of the stated redemption
price at maturity of the security over the price at which the security is sold
to the public. To the extent a holder of a senior debt security receives a
payment (at the time of acceleration of maturity, for example) that represents
payment of original issue discount already included by the holder in ordinary
income or reflected in the holder's tax basis in the security, that holder
generally will not be required to include the payment in income. The specific
terms of any senior debt securities that are issued with original issue discount
and the application of the original discount rules under the Internal Revenue
Code to those securities will be described in a prospectus supplement for those
securities.

     Payments of interest on debt securities will be made at the corporate trust
office of the trustee or at our option by check mailed to the registered holders
of debt securities or, if so provided in the applicable prospectus supplement,
at the option of a holder by wire transfer to an account designated by such
holder.

     Unless otherwise provided in the applicable prospectus supplement, debt
securities may be transferred or exchanged at the office of the trustee at which
its corporate trust business is principally administered in the United States,
subject to the limitations provided in the indenture, without the payment of any
service charge, other than any applicable tax or governmental charge.

Global Securities

     The debt securities of a series may be issued in whole or in part in the
form of one or more fully registered global securities that will be deposited
with a depositary or its nominee identified in the prospectus supplement
relating to such series. In that case, one or more global securities will be
issued in a denomination or aggregate denominations equal to the portion of the
aggregate principal amount of outstanding registered debt securities of the
series to be represented by such global security or securities. Until it is
exchanged in whole or in part for debt securities in definitive registered form,
a global security may not be transferred except as a whole by the depositary for
such global security to a nominee of such depositary or by a nominee of such
depositary to such depositary or another nominee of such depositary or by such
depositary or any such nominee to a successor of such depositary or a nominee of
such successor.

     The specific terms of any depositary arrangement will be described in the
prospectus supplement relating to such series. We anticipate that the following
provisions will apply to all depositary arrangements.

     If we issue a global security, the depositary for such global security will
credit on its system, the respective principal amounts of the debt securities
represented by such global security to the accounts of persons that have
accounts with such depositary ("participants"). The underwriters or agents
participating in the distribution of the debt securities will designate the
amounts to be credited. Ownership of beneficial interests in a global security
will be limited to participants or persons that may hold interests through
participants. Ownership and transfer of beneficial interests in the global
security will be effected only through, records maintained by the depositary for
the global security (with respect to interests of participants) or by
participants or persons that hold through participants (with respect to
interests of persons other than participants). While depositary for a global
security, or its nominee, is the registered owner of such global security, the
depositary or such nominee, as the case may be, will be the sole owner or holder
of the debt securities represented by such global security for all purposes
under the indenture. Except as set forth below, owners of beneficial interests
in a global security will not be entitled to have the debt securities
represented by such global security registered in their names, will not receive
or be entitled to receive physical delivery of such debt securities and will not
be considered the owners or holders of such debt securities under the indenture.

     Principal, premium, if any, and interest payments on debt securities
represented by a global security registered in the name of a depositary or its
nominee will be made to the depositary or its nominee, as the case may be, as
the registered owner of the global security. We, the trustee or any paying agent
for such debt securities will not have any responsibility or liability for the
records relating to or payments made on account of beneficial ownership
interests in the global securities or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

     We expect that the depositary for any debt securities represented by a
global security, on receipt of any payment of principal, premium, or interest,
will immediately credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such global security as shown on the records of such depositary. We also
expect that

                                      -9-


payments by participants to owners of beneficial interests in the global
security held through such participants will be governed by standing
instructions and customary practices, as is now the case with the securities
held for the accounts of customers registered in "street name," and will be the
responsibility of such participants.

     If the depositary for any debt securities represented by a global security
is at any time unwilling or unable to continue as depositary and a successor
depositary is not appointed by us within 90 days, we will issue the debt
securities in exchange for the global security. Also, we may determine not to
have any of the debt securities of a series represented by one or more global
securities and, in that event, will issue debt securities of such series in
definitive form in exchange for the global security or Securities representing
such debt securities.

Subordination

     Debt securities may be subordinated to the prior payment of all our
indebtedness that is designated as "senior indebtedness." Senior indebtedness,
with respect to any series of subordinated debt securities, will consist of any
of our indebtedness that is designated in a resolution of our board of directors
or the supplemental indenture establishing such series as senior indebtedness
with respect to such series.

     If we make a payment or distribution of our assets to our creditors or if
there is a total or partial liquidation or we are dissolved or we file for
bankruptcy, receivership, or similar proceeding, the holders of the senior
indebtedness will be paid in full before the holders of the subordinated debt
would receive any payment with respect to the subordinated debt securities.
Until the senior indebtedness is paid in full, there would be no distribution to
the holders of the subordinated debt securities (except that the holders may
receive shares of stock and any debt securities that are subordinated to senior
indebtedness to at least the same extent as the subordinated debt securities).

     We may not make any payments of principal, premium, or interest with
respect to subordinated debt securities, make any deposit for the purpose of
defeasance of such subordinated debt securities, or repurchase, redeem, or
otherwise retire (except, in the case of subordinated debt securities that
provide for a mandatory sinking fund, by the delivery of subordinated debt
securities by us to the trustee in satisfaction of our sinking fund obligation)
any subordinated debt securities if:

     (a) any principal, premium, if any, or interest with respect to senior
     indebtedness is not paid within any applicable grace period (including at
     maturity), or

     (b) any other default on senior indebtedness occurs and the maturity of
     such senior indebtedness is accelerated in accordance with its terms,

     unless, in either case,

          (i) the default has been cured or waived and such acceleration has
          been rescinded,

          (ii) such senior indebtedness has been paid in full in cash, or

          (iii) we and the trustee receive written notice approving such payment
          from the representatives of each issue of "designated senior
          indebtedness" (which will include any specified issue of senior
          indebtedness).

     During any default (other than a default described in clause (a) or (b)
above) on any senior indebtedness under which the maturity of the senior
indebtedness may be accelerated without further notice (except any notice
required to effect the acceleration) or the expiration of any applicable grace
periods, we may not pay the subordinated debt securities for a period (the
"payment blockage period") starting on our receipt and the trustee's receipt of
written notice of the election to effect a payment blockage period and ending
179 days thereafter. The payment blockage period may be terminated before its
expiration by written notice to the trustee and to us from the person who gave
the blockage notice, by repayment in full in cash of the senior indebtedness
with respect to which the blockage notice was given, or because the default
giving rise to the payment blockage period is no longer continuing. Unless the
holders of the senior indebtedness have accelerated the maturity of the senior
indebtedness, we may resume payments on the subordinated debt securities after
the expiration of the payment blockage period. Not more than one blockage notice
may be given in any period of 360 consecutive days unless the first blockage
notice within such 360-day period is given by or on behalf of holders of
designated senior indebtedness other than the bank indebtedness, in which case
the representative of the bank indebtedness may give another blockage notice
within such period. In no event, however, may the total number of days during
which any payment blockage period or periods is in effect exceed 179 days in the
aggregate during any period of 360 consecutive days. After all senior
indebtedness is paid in full and until the subordinated debt securities are paid
in full, holders of the subordinated debt securities shall be subrogated to the
rights of holders of senior indebtedness to receive distributions applicable to
senior indebtedness.

     As a result of the subordination provisions, in the event of our bankruptcy
or insolvency, our creditors who are holders of senior indebtedness, as well as
certain of our general creditors, may recover ratably more than the holders of
the subordinated debt securities.

                                      -10-


Events of Default and Remedies

     The following events are defined in the indenture as "events of default"
with respect to a series of debt securities:

     (a) a default in the payment of any installment of interest (whether or
     not, in the case of subordinated debt securities, such payment shall be
     prohibited by reason of the subordination provision described above) and
     continuance of such default for a period of 30 days;

     (b) a default in the payment of principal or premium, if any, whether at
     maturity, upon redemption, by declaration, upon required repurchase, or
     otherwise (whether or not, in the case of subordinated debt securities,
     such payment shall be prohibited by reason of the subordination provision
     described above);

     (c) a default in the payment of any sinking fund payment;

     (d) we fail to comply with the provisions of the indenture relating to
     consolidations, mergers and sales of assets;

     (e) we fail to observe or perform any other covenants or agreements in the
     debt securities, in any resolution of our board of directors authorizing
     the issuance of the debt securities, in the indenture, or in any
     supplemental indenture (other than a covenant or agreement a default in the
     performance of which is otherwise specifically dealt with) for a period of
     60 days following the date we receive proper written notice specifying the
     failure;

     (f) we do not pay our indebtedness within any applicable grace period after
     final maturity or the indebtedness is accelerated by the holders of the
     indebtedness because of a default, the total amount of such indebtedness
     unpaid or accelerated exceeds the amount specified or the United States
     dollar equivalent of the amount specified million at the time, and such
     default remains uncured or such acceleration is not rescinded for 10 days
     after the date on which written notice specifying such failure and
     requiring us to remedy such failure shall have been given to us by the
     trustee or to us and the trustee by the holders of at least 25% in
     aggregate principal amount of the debt securities of that series at the
     time outstanding;

     (g) we

          (1) voluntarily commence any proceeding or file any petition seeking
          relief under the United States Bankruptcy Code or other federal or
          state bankruptcy, insolvency, or similar law,

          (2) consent to the institution of, or fail to controvert within the
          time and in the manner prescribed by law, any such proceeding of the
          filing of any such petition,

          (3) apply for or consent to the appointment of a receiver, trustee,
          custodian, sequestrator, or similar official for us for a substantial
          part of our property,

          (4) file an answer admitting the material allegations of a petition
          filed against us in any such proceeding,

          (5) make a general assignment for the benefit of our creditors,

          (6) admit in writing our inability or fail generally to pay our debts
          as they become due,

          (7) take corporate action for the purpose of effecting any of the
          foregoing, or

          (8) take any comparable action under any foreign laws relating to
          insolvency;

     (h) the entry of an order or decree by a court having competent
     jurisdiction for

          (1) relief with respect to us or a substantial part of our property
          under the United States Bankruptcy Code or any other federal or state
          bankruptcy, insolvency, or similar law,

          (2) the appointment of a receiver, trustee, custodian, sequestrator,
          or similar official for us or for a substantial part of our property,
          or

          (3) our winding-up or liquidation;

     and such order or decree shall continue unstayed and in effect for 60
     consecutive days, or any similar relief is granted under any foreign laws
     and the order or decree stays in effect for 60 consecutive days; or

     (i) any other event of default provided under the terms of the debt
     securities of that series.

     An event of default with respect to one series of debt securities is not
necessarily an event of default for another series.

                                      -11-


     If an event of default occurs and is continuing with respect to any series
of debt securities, unless the principal and interest with respect to all the
debt securities of such series shall have already become due and payable, either
the trustee or the holders of not less than 25% in aggregate principal amount of
the debt securities of such series then outstanding may declare the principal of
(or, if original issue discount debt securities, such portion of the principal
amount as may be specified in such series) and interest on all the debt
securities of such series due and payable immediately.

     If an event of default occurs and is continuing, the trustee shall be
entitled and empowered to institute any action or proceeding for the collection
of the sums so due and unpaid or to enforce the performance of any provision of
the debt securities of the affected series or the indenture, to prosecute any
such action or proceeding to judgment or final decree, and to enforce any such
judgment or final decree against us or any other obligor on the debt securities
of such series. In addition, if there is pending proceedings for the bankruptcy
or reorganization of the company or any other obligor on the debt securities, or
if a receiver, trustee, or similar official shall have been appointed for our
property, the trustee shall be entitled and empowered to file and prove a claim
for the whole amount of principal, premium and interest (or, in the case of
original issue discount debt securities, such portion of the principal amount as
may be specified in the terms of such series) owing and unpaid with respect to
the debt securities. No holder of any debt securities of any series shall have
any right to institute any action or proceeding upon or under or with respect to
the indenture, for the appointment of a receiver or trustee, or for any other
remedy, unless:

     (a) such holder previously will have given to the trustee written notice of
     an event of default with respect to debt securities of that series and of
     the continuance of such event of default;

     (b) the holders of not less than 25% in aggregate principal amount of the
     outstanding debt securities of that series will have made written request
     to the trustee to institute such action or proceeding with respect to the
     event of default and will have offered to the trustee such reasonable
     indemnity as it may require against the costs, expenses, and liabilities to
     be incurred in connection with such action or proceeding; and

     (c) the trustee, for 60 days after its receipt of such notice, request, and
     offer of indemnity will have failed to institute such action or proceeding
     and no direction inconsistent with such written request shall have been
     given to the trustee pursuant to the provisions of the indenture.

     Prior to the acceleration of the maturity of the debt securities of any
series, the holders of a majority in aggregate principal amount of the debt
securities of that series at the time outstanding may, on behalf of the holders
of all debt securities of that series, waive any past default or event of
default and its consequences for that series, except:

     (a) a default in the payment of the principal, premium, if any, or interest
     with respect to such debt securities; or

     (b) a default with respect to a provision of the indenture that cannot be
     amended without the consent of each holder so affected.

     In case of any such waiver, the default shall cease to exist, any event of
default arising from the default will be deemed to have been cured for all
purposes, and we, the trustee and the holders of the debt securities of that
series will each be restored to their former positions and rights under the
indenture.

     The trustee will, within 90 days after the occurrence of a default known to
it with respect to a series of debt securities, give to the holders of the debt
securities notice of all uncured defaults known to it, unless the defaults will
have been cured or waived before the giving of such notice; provided, however,
that except in the case of default in the payment of principal, premium, or
interest with respect to the debt securities or in the making of any sinking
fund payment with respect to the debt securities, the trustee will be protected
in withholding such notice if it in good faith determines that the withholding
of such notice is in the interest of the holders of the debt securities.

Modification of the indenture

     We and the trustee may enter into supplemental indentures without the
consent of the holders of debt securities issued under the indenture for one or
more of the following purposes:

     (a) to evidence our succession by another person and the assumption by such
     successor of our covenants, agreements, and obligations in the indenture
     and in the debt securities;

     (b) to surrender any right or power conferred upon us by the indenture, to
     add further covenants, restrictions, conditions, or provisions for the
     protection of the holders of all or any series of debt securities, and to
     make the occurrence, or the occurrence and continuance of a default in any
     of such additional covenants, restrictions, conditions, or provisions, a
     default or an event of default under the indenture;

     (c) to cure any ambiguity or to correct or supplement any provision
     contained in the indenture, in any supplemental indenture, or in any debt
     securities that may be defective or inconsistent with any other provision
     contained in the indenture,

                                      -12-


     in any supplemental indenture, or in any debt securities, to convey,
     transfer, assign, mortgage, or pledge any property to or with the trustee,
     or to make such other provisions in regard to matters or questions arising
     under the indenture as shall not adversely affect the interests of any
     holders of debt securities of any series;

     (d) to modify or amend the indenture in such a manner as to permit the
     qualification of the indenture or any supplemental indenture under the
     Trust indenture Act as then in effect;

     (e) to add or change any of the provisions of the indenture to change or
     eliminate any restriction on the payment of principal or premium with
     respect to debt securities so long as any such action does not adversely
     affect the interest of the holders of debt securities in any material
     respect or permit or facilitate the issuance of debt securities of any
     series in uncertificated form;

     (f) to comply with the provisions of the indenture relating to
     consolidations, mergers, and sales of assets;

     (g) in the case of subordinated debt securities, to make any change in the
     provisions of the indenture relating to subordination that would limit or
     terminate the benefits available to any holder of senior indebtedness under
     such provisions (but only if such holder of senior indebtedness consents to
     such change);

     (h) to add guarantees with respect to the debt securities or to secure the
     debt securities;

     (i) to add to, change, or eliminate any of the provisions of the indenture
     with respect to one or more series of debt securities, so long as any such
     addition, change, or elimination not otherwise permitted under the
     indenture shall

          (1) neither apply to any debt securities of any series created prior
          to the execution of such supplemental indenture and entitled to the
          benefit of such provision nor modify the rights of the holders of any
          such debt security with respect to such provision, or

          (2) become effective only when there is no such debt security
          outstanding;

     (j) to evidence and provide for the acceptance of appointment by a
     successor or separate trustee with respect to the debt securities of one or
     more series and to add to or change any of the provisions of the indenture
     as shall be necessary to provide for or facilitate the administration of
     the indenture by more than one trustee; and

     (k) to establish the form or terms of any series of debt securities.

     With the consent of the holders of a majority in aggregate principal amount
of the outstanding debt securities of each series affected, we and the trustee
may from time to time and at any time enter into a supplemental indenture for
the purpose of adding any provisions to, changing in any manner, or eliminating
any of the provisions of the indenture or of any supplemental indenture or
modifying in any manner the rights of the holder of the debt securities of such
series. However, without the consent of the holders of each debt security so
affected, no such supplemental indenture may:

     .   reduce the percentage in principal amount of debt securities of any
         series whose holders must consent to an amendment;

     .   reduce the interest rate or extend the time for payment of interest on
         any debt security;

     .   reduce the principal of or extend the stated maturity of any debt
         security;

     .   reduce the premium payable upon the redemption of any debt security or
         change the time at which any debt security may or shall be redeemed;

     .   make any debt security payable in a currency other than that stated in
         the debt security;

     .   in the case of any subordinated debt security, make any change in the
         provisions of the indenture relating to subordination that adversely
         affects the rights of any holder under such provisions;

     .   release any security that may have been granted with respect to the
         debt securities; or

     .   make any change in the provisions of the indenture relating to waivers
         of defaults or amendments that require unanimous consent.

Consolidation, Merger, and Sale of Assets

     The indenture provides that we may not consolidate with or merge with or
into any person, or convey, transfer, or lease all or substantially all of our
assets, unless the following conditions have been satisfied:

                                      -13-


     (a) Either

          (i) We are the continuing person in the case of a merger, or

          (ii) the successor corporation is a corporation organized and existing
          under the laws of the United States, any State, or the District of
          Columbia and shall expressly assume all of our obligations under the
          debt securities and the indenture;

     (b) Immediately after giving effect to the transaction (and treating any
     indebtedness that becomes an obligation of the successor corporation or any
     of our subsidiaries as a result of the transaction as having been incurred
     by the successor corporation or a subsidiary at the time of the
     transaction), no default or event of default would occur or be continuing;
     and

     (c) We have delivered to the trustee an officers' certificate and an
     opinion of counsel, each stating that the consolidation, merger, or
     transfer complies with the indenture.

Satisfaction and Discharge of the Indenture

     The indenture provides, among other things, that when all debt securities
not previously delivered to the trustee for cancellation (1) have become due and
payable or (2) will become due and payable at their stated maturity within one
year, we may deposit with the trustee funds, in trust, for the purpose and in an
amount sufficient to pay and discharge the entire indebtedness on the debt
securities not previously delivered to the trustee for cancellation. Those funds
will include all principal, premium, if any, and interest, if any, to the date
of the deposit or to the stated maturity, as applicable. Upon such deposit, the
indenture will cease to be of further effect except as to our obligations to pay
all other sums due under the indenture and to provide the officers' certificates
and opinions of counsel required under the indenture. At such time we will be
deemed to have satisfied and discharged the indenture.

Governing Law

     The indenture and the debt securities will be governed by, and construed in
accordance with, the laws of the State of New York.

Regarding the Trustee

     Information concerning the trustee for a series of debt securities will be
set forth in the prospectus supplement relating to that series of debt
securities.

     We may have normal banking relationships with the trustee in the ordinary
course of business.

                          DESCRIPTION OF CAPITAL STOCK

     We have 80,000,000 authorized shares of capital stock, consisting of (a)
75,000,000 shares of common stock, having a par value of $.20 per share, and (b)
5,000,000 shares of preferred stock, having a par value of $1.00 per share. As
of December 31, 2002, there were 43,339,400 shares of our common stock
outstanding. No preferred stock is outstanding.

Common Stock

     Dividends are paid to the holders of our common stock, when, as and if
declared by our board of directors. The provisions of our credit arrangements
subject us to certain restrictions on the payment of dividends.

     In the event of our voluntary or involuntary liquidation, dissolution or
winding up, the holders of our common stock will be entitled to share equally in
our assets remaining after payment of all liabilities and after the holders of
all series of outstanding preferred stock have received their liquidation
preferences in full.

     The holders of our common stock have no preemptive subscription, conversion
or redemption rights, and are not subject to further calls or assessments by us.
There are no sinking fund provisions applicable to the common stock.

     Holders of our common stock are entitled to one vote per share for the
election of directors and on all other matters submitted to a vote of
stockholders. Holders of common stock have no right to cumulate their votes in
the election of directors.

Preferred Stock

     Preferred stock may be issued from time to time in one or more series, and
our board of directors, without further approval of our stockholders, is
authorized to fix the dividend rates and terms, conversion rights, voting
rights, redemption rights and terms, liquidation preferences, sinking fund and
any other rights, preferences, privileges and restrictions applicable to each
series of preferred stock. The purpose of authorizing the board of directors to
determine such rights, preferences, privileges and restrictions is to

                                      -14-

eliminate delays associated with a stockholder vote on specific issuances. The
issuance of preferred stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could, among other things:

     .   decrease the amount of earnings and assets available for distribution
         to holders of common stock;

     .   adversely affect the rights and powers, including voting rights, of
         holders of common stock; and

     .   have the effect of delaying, deferring or preventing a change in
         control.

Stockholder Rights Agreement

     Each share of common stock includes one right ("right") entitling the
registered holder to purchase from us one one-hundredth of a share (a
"fractional share") of Series A Participating Cumulative Preferred Stock (the
"preferred shares"), at a purchase price per fractional share of $70.00, subject
to adjustment (the "purchase price").

     With certain exceptions, upon the earlier of (1) 10 days following the date
we learn that a person or group of affiliated or associated persons (an
"acquiring person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of our outstanding shares of common stock, or (2) 10
business days following the commencement of a tender offer or exchange offer
that would result in a person becoming an acquiring person, a "distribution
date" will occur and the rights will be separated from the common stock. In
certain circumstances, our board of directors may defer the distribution date.
Certain inadvertent acquisitions will not result in a person becoming an
acquiring person if the person promptly divests itself of sufficient common
stock. Until the distribution date, (1) the rights are evidenced by the
certificates representing outstanding shares of common stock and will be
transferred with and only with such certificates, which contain a notation
incorporating the rights agreement by reference, and (2) the surrender for
transfer of any certificate for common stock will also constitute the transfer
of the rights associated with the common stock represented by such certificate.

     The rights are not exercisable until the distribution date and will expire
at the close of business 10 years after the rights are issued, unless earlier
redeemed or exchanged by us as described below.

     As soon as practicable after the distribution date, rights certificates
will be mailed to holders of record of the common stock as of the close of
business on the distribution date and, from and after the distribution date, the
separate rights certificates alone will represent the rights. All shares of
common stock issued prior to the distribution date will be issued with rights.
Shares of common stock issued after the distribution date in connection with
certain employee benefit plans or upon conversion of certain securities will be
issued with rights. Except as otherwise determined by the board of directors, no
other shares of the common stock issued after the distribution date will be
issued with rights.

     In the event (a "flip-in event") that a person becomes an acquiring person
(except pursuant to a tender or exchange offer for all outstanding shares of
common stock at a price and on terms that a majority of our independent
directors determines to be fair to our stockholders and otherwise in our and our
stockholders' best interests (a "permitted offer")), each holder of a right will
thereafter have the right to receive, upon exercise of that right, the number of
fractional shares equivalent to the number of shares of common stock (or, in
certain circumstances, cash, property or other securities) having a market value
equal to two times the purchase price. Notwithstanding the foregoing, following
the occurrence of any flip-in event or flip-over event (as described below), all
rights that are, or (under certain circumstances specified in the rights
agreement) were, beneficially owned by or transferred to an acquiring person (or
by certain related parties) will be null and void in the circumstances set forth
in the rights agreement.

     In the event (a "flip-over event") that, at any time from and after the
time an acquiring person becomes such, (1) we are acquired in a merger or other
business combination transaction (other than certain mergers that follow a
permitted offer) or (2) 50% or more of our assets or earning power is sold or
transferred, each holder of a right (except rights that are voided as set forth
above) shall thereafter have the right to receive, upon exercise, a number of
shares of common stock of the acquiring company having a market value equal to
two times the exercise price of the right as set by the board of directors. The
number of outstanding rights associated with a share of common stock, or the
number of preferred shares issuable upon exercise of a right and the purchase
price, are subject to adjustment in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the common stock occurring
prior to the distribution date. The purchase price payable, and the number of
fractional shares of preferred shares or other securities or property issuable,
upon exercise of the rights are subject to adjustment from time to time to
prevent dilution in the event of certain transactions affecting the preferred
shares.

     At any time until ten days following the first date of public announcement
of the occurrence of a flip-in event, we may redeem the rights in whole, but not
in part, at a price of $0.01 per right, payable, at our option, in cash, shares
of common stock or such other consideration as our board of directors may
determine. Immediately upon the effectiveness of the action of the board of
directors ordering redemption of the rights, the rights will terminate and the
only right of the holders of rights will be to receive the $0.01 redemption
price.

                                      -15-


     Until a right is exercised, the holder thereof, as such, will have no
rights as a stockholder, including, without limitation, the right to vote or to
receive dividends.

     Other than the redemption price, our board of directors may amend any of
the provisions of the rights agreement as long as the rights are redeemable.

     The rights have certain antitakeover effects. They will cause substantial
dilution to any person or group that attempts to acquire us without the approval
of our board of directors. As a result, the overall effect of the rights may be
to render more difficult or discourage any attempt to acquire us, even if that
acquisition may be favorable to the interests of our stockholders. Because the
board of directors can redeem the rights or approve a permitted offer, the
rights should not interfere with a merger or other business combination approved
by the board of directors. The rights were issued to protect our stockholders
from coercive or abusive takeover tactics and inadequate takeover offers and to
afford our board of directors more negotiating leverage in dealing with
prospective acquirors.

Certain Other Possible Anti-takeover Provisions

     Our charter and Delaware law contain certain provisions that might be
characterized as anti-takeover provisions. These provisions may make it more
difficult to acquire control of us or remove our management.

Classified Board of Directors

     Our charter provides for the board of directors to be divided into three
classes of directors serving staggered three-year terms, with the number of
directors in each class to be as nearly equal as possible. As a result, about
one-third of our directors are elected each year.

Issuance of Preferred Stock

     As described above, our charter authorizes a class of undesignated
preferred stock consisting of 5,000,000 shares. The issuance of preferred stock
could, among other things, make it more difficult for a third party to gain
control of us.

Fair Price Provisions

     Our charter also contains certain "fair price provisions" designated to
provide safeguards for stockholders when an "interested stockholder" (defined as
a stockholder owning 5% or more of our voting stock) attempts to effect a
"business combination" with us. The term "business combination" includes:

     .   any merger or consolidation of us involving the interested stockholder,

     .   certain dispositions of our assets,

     .   any issuance of our securities meeting certain threshold amounts, to
         the interested stockholder,

     .   adoption of any plan of liquidation or dissolution of us proposed by
         the interested stockholder, and

     .   any reclassification of our securities having the effect of increasing
         the proportionate share of ownership of the interested stockholder.

     In general, a business combination between us and the interested
stockholder must be approved by the affirmative vote of 80% of the outstanding
voting stock unless the transaction is approved by a majority of the members of
the board of directors who are not affiliated with the interested stockholder or
certain minimum price and form of consideration requirements are satisfied.

Delaware Business Combination Statute

     We are incorporated under the laws of the State of Delaware. Section 203 of
the Delaware General Corporation Law prevents an "interested stockholder"
(defined as a stockholder owning 15% or more of a corporation's voting stock)
from engaging in a business combination with that corporation for a period of
three years from the date the stockholder became an interested stockholder
unless:

     .   the corporation's board of directors had earlier approved either the
         business combination or the transaction by which the stockholder became
         an interested stockholder;

     .   upon attaining that status, the interested stockholder had acquired at
         least 85% of the corporation's voting stock (not counting shares owned
         by persons who are directors and also officers); or

                                      -16-


     .   the business combination is later approved by the board of directors
         and authorized by a vote of two-thirds of the stockholders (not
         including the shares held by the interested stockholder).

     Since we have not amended our charter or by-laws to exclude the application
of Section 203, its provisions apply to us. Accordingly, Section 203 may inhibit
an interested stockholder's ability to acquire additional shares of common stock
or otherwise engage in a business combination with us.

Advance Notice for Raising Business or Making Nominations at Meetings

     Our by-laws establish an advance notice procedure for stockholder proposals
to be brought before an annual meeting of stockholders and for nominations by
stockholders of candidates for election as directors at an annual or special
meeting at which directors are to be elected.

     Only such business may be conducted at an annual meeting of stockholders as
has been brought before the meeting by, or at the direction of, the board of
directors or by a stockholder who has given to our secretary timely written
notice, in proper form, of the stockholder's intention to bring that business
before the meeting. Only persons who are nominated by, or at the direction of,
the board of directors, or who are nominated by a stockholder who has given
timely written notice, in proper form, to the secretary prior to a meeting at
which directors are to be elected will be eligible for election as directors.
The person presiding at the meeting will have the authority to make
determinations whether a stockholder's notice complies with the procedures in
our by-laws.

     To be timely, notice of business to be brought before an annual meeting or
nominations of candidates for election as directors at an annual meeting is
generally required to be received by our secretary not later than 90 days nor
earlier than 120 days prior to the first anniversary of the prior years annual
meeting date.

     The notice of any nomination for election as a director is required to set
forth the information regarding that person required in our by-laws as well as
by paragraphs (a), (e), and (f) of Item 401 of regulation S-K adopted by the
SEC.

Transfer Agent and Registrar

     We may issue purchase contracts, including contracts obligating holders to
purchase from us and us to sell to the holders, a specified principal amount of
debt securities or a specified number of shares of common stock or preferred
stock or any of the other securities that we may sell under this prospectus (or
a range of principal amount or number of shares pursuant to a predetermined
formula) at a future date or dates. The consideration payable upon settlement of
the purchase contracts may be fixed at the time the purchase contracts are
issued or may be determined by a specific reference to a formula set forth in
the purchase contracts. The purchase contracts may be issued separately or as
part of units consisting of a purchase contract and other securities or
obligations issued by us or third parties, including United States treasury
securities, securing the holders' obligations to purchase the relevant
securities under the purchase contracts.

                                      -18-


     The purchase contracts may require us to make periodic payments to the
holders of the purchase contracts or units or vice versa, and the payments may
be unsecured or prefunded on some basis. The purchase contracts may require
holders to secure their obligations under the purchase contracts in a specified
manner and in some circumstances we may deliver newly issued prepaid purchase
contracts, often referred to as "prepaid securities," upon release to a holder
of any collateral securing such holder's obligations under the original purchase
contract.

     The applicable prospectus supplement will describe the terms of any
purchase contracts or purchase units and, if applicable, such other securities
or obligations. The description in the prospectus supplement will not
necessarily be complete and will be qualified in its entirety by reference to
the purchase contracts, and, if applicable, collateral arrangements, relating to
the purchase contracts.

     We may issue units consisting of one or more purchase contracts, warrants,
debt securities, shares of preferred stock, shares of common stock or any
combination of such securities. The applicable prospectus supplement will

         securities, preferred stock and/or common stock comprising the units,
         including whether and under what circumstances the securities
         comprising the units may be traded separately;

     .   a description of the terms of any unit agreement governing the units;
         and

     .   a description of the provisions for the payment, settlement, transfer
         or exchange of the units.

                              PLAN OF DISTRIBUTION

     We may sell offered securities in any one or more of the following ways
from time to time

     .   through agents,

     .   to or through underwriters,

     .   through dealers,

     .   directly to purchasers, or

     .   through a combination of these methods or through any other method
         permitted by law.

Any underwriter, dealer or agent may be deemed to be an "underwriter" within the
meaning of the Securities Act.

     The prospectus supplement with respect to the offered securities will set
forth the terms of the offering, including

     .   the name or names of any underwriters, dealers or agents,

     .   the purchase price and the proceeds to us from the sale,

     .   any underwriting discounts and commissions or agency fees and other
         items constituting underwriters' or agents' compensation,

     .   any over-allotment options under which underwriters may purchase
         additional securities from us,

     .   any initial public offering price and any discounts or concessions
         allowed or reallowed or paid to dealers, or

     .   any trading market or securities exchange on which the offered
         securities may be listed.

Any initial public offering price, discounts or concessions allowed or reallowed
or paid to dealers may be changed from time to time.

     The distribution of the offered securities may be effected from time to
time in one or more transactions:

     .   at a fixed price or prices (which may be changed),

     .   at market prices prevailing at the time of sale,

                                      -19-


     .   at prices related to such prevailing market prices, or

     .   at negotiated prices.

Offers to purchase offered securities may be solicited by agents designated by
us from time to time. Any agent involved in the offer or sale of the offered
securities will be named, and any commissions payable by us to the agent will be
set forth in the applicable prospectus supplement. Unless otherwise indicated in
the prospectus supplement, the agent will be acting on a reasonable best efforts
basis for the period of its appointment.

     If offered securities are sold by means of an underwritten offering, we
will execute an underwriting agreement with an underwriter or underwriters, and
the names of the specific managing underwriter or underwriters, as well as any
other underwriters, and the terms of the transaction, including commissions,
discounts and any other compensation of the underwriters and dealers, if any,
will be set forth in the prospectus supplement which will be used by the
underwriters to make resales of the offered securities. If underwriters are
utilized in the sale of the offered securities, the offered securities will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at fixed
public offering prices or at varying prices determined by the underwriters at
the time of sale. Our offered securities may be offered to the public either
through underwriting syndicates represented by managing underwriters or directly
by the managing underwriters. If any underwriter or underwriters are utilized in
the sale of the offered securities, unless otherwise indicated in the prospectus
supplement, the underwriting agreement will provide that the obligations of the
underwriters are subject to certain conditions precedent and that the
underwriters with respect to a sale of offered securities will be obligated to
purchase all such offered securities of a series if any are purchase.

     We may grant to the underwriters options to purchase additional offered
securities, to cover over-allotments, if any, at the public offering price, with
additional underwriting discounts or commissions, as may be set forth in the
prospectus supplement relating thereto. If we grant any over-allotment option,
the terms of the over-allotment option will be set forth in the prospectus
supplement relating to the offered securities.

     If a dealer is utilized in the sales of offered securities we will sell
such offered securities to the dealer as principal. The dealer may then resell
such offered securities to the public at varying prices to be determined by the
dealer at the time of resale. The dealer may be deemed to be an underwriter, as
the term is defined in the Securities Act, of the offered securities so offered
and sold. The name of the dealer and the terms of the transaction will be set
forth in the related prospectus supplement.

     Offers to purchase offered securities may be solicited directly by us and
the sale may be made by us directly to institutional investors or others, who
may be deemed to be underwriters within the meaning of the Securities Act with
respect to any resale thereof. The terms of the sales will be described in the
related prospectus supplement.

     Offered securities may also be offered and sold, if so indicated in the
applicable prospectus supplement, in connection with a remarketing upon their
purchase, in accordance with a redemption or repayment pursuant to their terms,
or otherwise, by one or more firms, acting as principals of their own accounts
or as agents for us. Any such remarketing firm will be identified and the terms
of its agreements, if any, with us and its compensation will be described in the
applicable prospectus supplement. Remarketing firms may be deemed to be
underwriters, as that term is defined in the Securities Act, in connection with
the offered securities remarketed thereby.

     Agents, underwriters, dealers and remarketing firms may be entitled under
relevant agreements entered into with us to indemnification by us against
certain civil liabilities, including liabilities under the Securities Act that
may arise from any untrue statement or alleged untrue statement of a material
fact or any omission or alleged omission to state a material fact in this
prospectus, any supplement or amendment hereto, or in the registration statement
of which this prospectus forms a part, or to contribution with respect to
payments which the agents, underwriters or dealers may be required to make.

     Each class or series of securities will be a new issue of securities with
no established trading market, other than our common stock, which is listed on
the New York Stock Exchange. We may elect to list any other class or series of
securities on any exchange, but are not obligated to do so. Any underwriters to
whom securities are sold by us for public offering and sale may make a market in
such securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for any securities.

                                  LEGAL MATTERS

     The validity of the offered securities will be passed upon for us by Conner
& Winters, P.C., Tulsa, Oklahoma, and for any underwriters, dealers or agents by
a firm named in the prospectus supplement relating to the particular securities.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 4 of our amended and restated by-laws provides for indemnification
of any person who is, or is threatened to be made, a witness in or a party to
any proceeding by reason of his or her position as one of our directors,
officers, or employees, to the extent authorized by applicable law including,
but not limited to, the Delaware General Corporation Law. Pursuant to Section
145 of the Delaware General Corporation Law, a corporation generally has the
power to indemnify its present and former directors, officers, employees and
agents against expenses and liabilities incurred by them in connection with any
suit to which they are, or are threatened to be made, a party by reason of their
serving in such positions so long as they acted in good faith and in a manner
they reasonably believed to be in, or not opposed to, the best interests of the
corporation, and with respect to any criminal action, they had no reasonable
cause to believe their conduct was unlawful. With respect to suits by or in the
right of a corporation, however, indemnification is generally limited to
attorney's fees and other expenses and is not available if such person is
adjudged to be liable to the corporation unless the court determines that
indemnification is appropriate. In addition, a corporation has the power to
purchase and maintain insurance for such persons. Article 4 of our by-laws also
expressly provides that the power to indemnify authorized thereby is not
exclusive of any rights granted to present and former directors, officers,
employees and agents, under any bylaw, agreement, vote of stockholders or
disinterested directors, or otherwise.

     Article Nine of our charter eliminates in certain circumstances the
monetary liability of our directors for a breach of their fiduciary duty as
directors. These provisions do not eliminate the liability of a director

     .   for a breach of the director's duty of loyalty to us or to our
         stockholders;

     .   for acts or omissions not in good faith or which involve intentional
         misconduct or knowing violation of law;

     .   under Section 174 of the Delaware General Corporation Law (relating to
         the declaration of dividends and purchase or redemption of shares in
         violation of the Delaware General Corporation Law); or

     .   for transactions from which the director derived an improper personal
         benefit.

     We have purchased directors and officers liability insurance that would
indemnify our directors and officers against damages arising out of certain
kinds of claims that might be made against them based on their negligent acts or
omissions while acting in their capacity as such.

     The above discussion of our charter, by-laws and of Section 145 of the
Delaware General Corporation Law is not exhaustive and is qualified in its
entirety by our charter, our by-laws and statute.

                     reflected in the form of prospectus filed with the SEC
                     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 this effective
                     registration statement;

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

                     provided, however, that paragraphs (i) and (ii) above do
                     not apply if the information required to be included in a
                     post-effective amendment by those paragraphs is contained
                     in periodic reports filed by the Registrant pursuant to
                     section 13 or section 15(d) of the Securities Exchange Act
                     of 1934 ("Exchange Act") that are incorporated by reference
                     in this registration statement.

                                      II-2


          (2)  That, for the purpose of determining any liability under the
               Securities Act, 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.

          (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 undersigned registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act, each filing of the
         Registrant's Annual Report pursuant to section 13(a) or section 15(d)
         of the Exchange Act (and, where applicable, each filing of an employee
         benefit plan's annual report pursuant to section 15(d) of the Exchange
         Act) that is incorporated by reference in this registration statement
         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) Insofar as indemnification for liabilities arising under the Securities
         Act may be permitted to directors, officers and controlling persons of
         the Registrant pursuant to the provisions described under Item 15
         above, or otherwise, the Registrant has been advised that, in the
         opinion of the SEC, such indemnification is against public policy as
         expressed in the Securities Act and is, therefore, unenforceable. In
         the event that a claim for indemnification against such liabilities
         (other than the payment by the 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, submit to a court of appropriate jurisdiction the question
         whether such indemnification by it is against public policy as
         expressed in the Securities Act and will be governed by the final
         adjudication of such issue.

     (d) The undersigned Registrant undertakes that:

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

                    (2) For the 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.

     (e) The undersigned 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 Trust Indenture Act ("Act") in
         accordance with the rules and regulations prescribed by the Commission
         under section 305(b)(2) of the Act.

          laws affecting the enforcement of creditors' rights generally and (ii)
          general principles of equity, whether such principles are considered
          in a proceeding at law or in equity;

          (d) that the Company has the corporate power to issue such Debt
          Securities and has duly taken all necessary corporate action with
          respect to such issuance;

          (e) that the issuance of such Debt Securities will not contravene the
          charter or by-laws of the Company or result in any material violation
          of any of the terms or provisions of any law or regulation or of any
          indenture, mortgage or other agreement known to such counsel by which
          the Company is bound;

          (f) that authentication and delivery of such Debt Securities and the
          execution and delivery of any supplemental Indenture will not violate
          the terms of this Indenture; and

          (g) such other matters as the Trustee may reasonably request.

Such Opinion of Counsel need express no opinion as to whether a court in the
United States would render a money judgment in a currency other than that of the
United States.

The Trustee shall have the right to decline to authenticate and deliver any Debt
Securities under this Section 2.05 if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee or a trust
committee of directors or trustees and/or vice presidents shall determine that
such action would expose the Trustee to personal liability to existing Holders
or would adversely affect the Trustee's rights, duties, obligations or
immunities under this Indenture in a manner which is not reasonably acceptable
to the Trustee.

The Trustee may appoint an authenticating agent reasonably acceptable to the
Company to authenticate Debt Securities of any series. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Debt
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, paying agent or agent
for service of notices and demands.

Unless otherwise provided in the form of Debt Security for any series, each Debt
Security shall be dated the date of its authentication.

SECTION 2.06. Denomination of Debt Securities. Unless otherwise provided in the
form of Debt Security for any series, the Debt Securities of each series shall
be issuable only as Registered Securities in such denominations as shall be
specified or contemplated by Section 2.03. In the absence of any such
specification with respect to the Debt Securities of any series, the Debt
Securities of such series shall be issuable in denominations of $1,000 and any
integral multiple thereof.

SECTION 2.07.  Registration of Transfer and Exchange.

          (a) The Company shall keep or cause to be kept a register for each
series of Registered Securities issued hereunder (hereinafter collectively
referred to as the "Debt Security Register"), in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfer or
exchange of Registered Securities as in this Article II provided. At all
reasonable times the Debt Security Register shall be open for inspection by the
Trustee. Subject to Section 2.15, upon due presentment for registration of
transfer of any Registered Security at any office or agency to be maintained by
the Company in accordance with the provisions of Section 4.02, the Company shall
execute and the Trustee shall authenticate and deliver in the name of the
transferee or transferees a new Registered Security or Registered Securities of
the same series, for a like aggregate principal amount and tenor, in authorized
denominations.

                                       12

Unless and until otherwise determined by the Company by resolution of the Board
of Directors, the register of the Company for the purpose of registration,
exchange or registration of transfer of the Registered Securities shall be kept
at the corporate trust office of the Trustee and, for this purpose, the Trustee
shall be designated "Registrar".

Registered Securities of any series (other than a Global Security) may be
exchanged for a like aggregate principal amount and tenor of Registered
Securities of the same series of other authorized denominations. Subject to
Section 2.15, Registered Securities to be exchanged shall be surrendered at the
office or agency to be maintained by the Company as provided in Section 4.02,
and the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor the Registered Security or Registered Securities which the
Holder making the exchange shall be entitled to receive.

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

All Debt Securities issued in exchange for or upon transfer of Debt Securities
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture as the Debt Securities
surrendered for such exchange or transfer. No service charge shall be made for
any exchange or registration of transfer of Debt Securities (except as provided
by Section 2.09), but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto, other than those expressly provided in this Indenture to be made at the
Company's own expense or without expense or without charge to the Holders.

The Company shall not be required (a) to issue, register the transfer of or
exchange any Debt Securities for a period of 15 days next preceding any mailing
of notice of redemption of Debt Securities of such series or (b) to register the
transfer of or exchange any Debt Securities selected, called or being called for
redemption in whole or in part, except, in the case of Debt Securities to be
redeemed in part, the portion thereof not to be so redeemed.

Prior to the due presentation for registration of transfer of any Debt Security,
the Company, the Trustee, any paying agent or any Registrar may deem and treat
the Person in whose name a Debt Security is registered as the absolute owner of
such Debt Security for the purpose of receiving payment of principal of, and
premium, if any, and (subject to Section 2.12(a)) interest on, such Debt
Security and for all other purposes whatsoever, whether or not such Debt
Security is overdue, and none of the Company, the Trustee, any paying agent or
Registrar shall be affected by notice to the contrary.

None of the Company, the Trustee, any agent of the Trustee, any paying agent or
any Registrar will have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

SECTION 2.08. Temporary Debt Securities. Pending the preparation of definitive
Debt Securities of any series, the Company may execute and the Trustee shall
authenticate and deliver temporary Debt Securities (printed, lithographed,
photocopied, typewritten or otherwise produced) of any authorized denomination,
and substantially in the form of the definitive Debt Securities in lieu of which
they are issued, in registered form and with such omissions, insertions and
variations as may be appropriate for temporary Debt Securities, all as may be
determined by the Company with the concurrence of the Trustee. Temporary Debt
Securities may contain such reference to any provisions of this Indenture as may
be appropriate. Every temporary Debt Security shall be executed by the Company
and be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with like effect, as the definitive Debt
Securities.

If temporary Debt Securities of any series are issued, the Company will cause
definitive Debt Securities of such series to be prepared without unreasonable
delay. After the preparation of definitive Debt Securities of such series, the
temporary Debt Securities of such series shall be exchangeable for definitive
Debt Securities of such series upon surrender of the temporary Debt Securities
of such series at the office or agency of the Company at a Place of

                                       13

Payment for such series, without charge to the Holder thereof, except as
provided in Section 2.07 in connection with a transfer, and upon surrender for
cancellation of any one or more temporary Debt Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Debt Securities of the same
series of authorized denominations and of like tenor. Until so exchanged,
temporary Debt Securities of any series shall in all respects be entitled to the
same benefits under this Indenture as definitive Debt Securities of such series,
except as otherwise specified as contemplated by Section 2.03(17) with respect
to the payment of interest on Global Securities in temporary form.

Upon any exchange of a portion of a temporary Global Security for a definitive
Global Security or for the individual Debt Securities represented thereby
pursuant to Section 2.07 or this Section 2.08, the temporary Global Security
shall be endorsed by the Trustee to reflect the reduction of the principal
amount evidenced thereby, whereupon the principal amount of such temporary
Global Security shall be reduced for all purposes by the amount so exchanged and
endorsed.

SECTION 2.09. Mutilated, Destroyed, Lost or Stolen Debt Securities. If (i) any
mutilated Debt Security is surrendered to the Trustee at its corporate trust
office or (ii) the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Debt Security, and there
is delivered to the Company and the Trustee such security or indemnity as may be
required by them to save each of them and any paying agent harmless, and neither
the Company nor the Trustee receives notice that such Debt Security has been
acquired by a bona fide purchaser, then the Company shall execute and, upon a
Company Order, the Trustee shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt
Security of the same series of like tenor, form, terms and principal amount,
bearing a number not contemporaneously Outstanding. Upon the issuance of any
substituted Debt Security, 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 connected therewith. In case any Debt
Security which has matured or is about to mature or which has been called for
redemption shall become mutilated or be destroyed, lost or stolen, the Company
may, instead of issuing a substituted Debt Security, pay or authorize the
payment of the same (without surrender thereof except in the case of a mutilated
Debt Security) if the applicant for such payment shall furnish the Company and
the Trustee with such security or indemnity as either may require to save it
harmless from all risk, however remote, and, in case of destruction, loss or
theft, evidence to the satisfaction of the Company and the Trustee of the
destruction, loss or theft of such Debt Security and of the ownership thereof.

Every substituted Debt Security of any series issued pursuant to the provisions
of this Section 2.09 by virtue of the fact that any Debt Security is destroyed,
lost or stolen shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Debt Security shall be
found at any time, and shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Debt Securities of that
series duly issued hereunder. All Debt Securities shall be held and owned upon
the express condition that the foregoing provisions are exclusive with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Debt
Securities, and shall preclude any and all other rights or remedies,
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement or payment of negotiable instruments or other
securities without their surrender.

SECTION 2.10. Cancellation of Surrendered Debt Securities. All Debt Securities
surrendered for payment, redemption, registration of transfer or exchange shall,
if surrendered to the Company or any paying agent or a Registrar, be delivered
to the Trustee for cancellation by it, or if surrendered to the Trustee, shall
be canceled by it, and no Debt Securities shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this Indenture. All canceled
Debt Securities held by the Trustee shall be disposed of by the Trustee in
accordance with its customary procedures, and certification by the Trustee of
their disposition shall be delivered to the Company, unless otherwise directed.
On request of the Company, the Trustee shall deliver to the Company canceled
Debt Securities held by the Trustee. If the Company shall acquire any of the
Debt Securities, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented thereby unless and until the same
are delivered or surrendered to the Trustee for cancellation. The Company may
not issue new Debt Securities to replace Debt Securities it has redeemed, paid
or delivered to the Trustee for cancellation.

SECTION 2.11. Provisions of the Indenture and Debt Securities for the Sole
Benefit of the Parties and the Holders. Nothing in this Indenture or in the Debt
Securities, expressed or implied, shall give or be construed to give to any

                                       14

Person, other than the parties hereto, the Holders or any Registrar or paying
agent or the holders of Senior Indebtedness, if any, any legal or equitable
right, remedy or claim under or in respect of this Indenture, or under any
covenant, condition or provision herein contained; all its covenants, conditions
and provisions being for the sole benefit of the parties hereto, the Holders and
any Registrar and paying agents and the holders of Senior Indebtedness, if any.

SECTION 2.12.  Payment of Interest; Rights Preserved.

          (a) Interest on any Registered Security that is payable and is
punctually paid or duly provided for on any interest payment date shall be paid
to the Person in whose name such Registered Security is registered at the close
of business on the regular record date for such interest notwithstanding the
cancellation of such Registered Security upon any transfer or exchange
subsequent to the regular record date. Payment of interest on Registered
Securities shall be made at the corporate trust office of the Trustee (except as
otherwise specified pursuant to Section 2.03), or at the option of the Company,
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Debt Security Register or, if provided pursuant to Section
2.03 and in accordance with arrangements satisfactory to the Trustee, at the
option of the Registered Holder by wire transfer to an account designated by the
Registered Holder.

          (b) Subject to the foregoing provisions of this Section 2.12 and
Section 2.17, each Debt Security of a particular series delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any
other Debt Security of the same series shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Debt
Security.

SECTION 2.13.  Securities Denominated in Foreign Currencies.

          (a) Except as otherwise specified pursuant to Section 2.03 for
Registered Securities of any series, payment of the principal of, and premium,
if any, and interest on, Registered Securities of such series will be made in
Dollars.

          (b) For the purposes of calculating the principal amount of Debt
Securities of any series denominated in a Foreign Currency or in units of two or
more Foreign Currencies for any purpose under this Indenture, the principal
amount of such Debt Securities at any time Outstanding shall be deemed to be the
Dollar Equivalent of such principal amount as of the date of any such
calculation.

In the event any Foreign Currency or currencies or units of two or more
Currencies in which any payment with respect to any series of Debt Securities
may be made ceases to be a freely convertible Currency on United States Currency
markets, for any date thereafter on which payment of principal of, or premium,
if any, or interest on, the Debt Securities of a series is due, the Company
shall select the Currency of payment for use on such date, all as provided in
the Debt Securities of such series. In such event, the Company shall, as
provided in the Debt Securities of such series, notify the Trustee of the
Currency which it has selected to constitute the funds necessary to meet the
Company's obligations on such payment date and of the amount of such Currency to
be paid. Such amount shall be determined as provided in the Debt Securities of
such series. The payment to the Trustee with respect to such payment date shall
be made by the Company solely in the Currency so selected.

SECTION 2.14. Wire Transfers. Notwithstanding any other provision to the
contrary in this Indenture, the Company may make any payment of monies required
to be deposited with the Trustee on account of principal of, or premium, if any,
or interest on, the Debt Securities (whether pursuant to optional or mandatory
redemption payments, interest payments or otherwise) by wire transfer of
immediately available funds to an account designated by the Trustee on or before
the date such moneys are to be paid to the Holders of the Debt Securities in
accordance with the terms hereof.

SECTION 2.15.  Securities Issuable in the Form of a Global Security.

          (a) If the Company shall establish pursuant to Sections 2.01 and 2.03
that the Debt Securities of a particular series are to be issued in whole or in
part in the form of one or more Global Securities, then the Company shall
execute and the Trustee or its agent shall, in accordance with Section 2.05,
authenticate and deliver, such Global

                                       15

Security or Securities, which (i) shall represent, and shall be denominated in
an amount equal to the aggregate principal amount of, the Outstanding Debt
Securities of such series to be represented by such Global Security or
Securities, or such portion thereof as the Company shall specify in an Officers'
Certificate or Company Order, (ii) shall be registered in the name of the
Depositary for such Global Security or securities or its nominee, (iii) shall be
delivered by the Trustee or its agent to the Depositary or pursuant to the
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect: "Unless and until it is exchanged in whole or in part for the
individual Debt Securities represented hereby, this Global Security may not be
transferred except as a whole by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary", or such other legend as may then be
required by the Depositary for such Global Security or Securities.

          (b) Notwithstanding any other provision of this Section 2.15 or of
Section 2.07 to the contrary, and subject to the provisions of paragraph (c)
below, unless the terms of a Global Security expressly permit such Global
Security to be exchanged in whole or in part for definitive Debt Securities in
registered form, a Global Security may be transferred, in whole but not in part
and in the manner provided in Section 2.07, only by the Depositary to a nominee
of the Depositary for such Global Security, or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary, or by the Depositary or a
nominee of the Depositary to a successor Depositary for such Global Security
selected or approved by the Company, or to a nominee of such successor
Depositary.

          (c)

          (i)   If at any time the Depositary for a Global Security or
                Securities notifies the Company that it is unwilling or unable
                to continue as Depositary for such Global Security or Securities
                or if at any time the Depositary for the Debt Securities for
                such series shall no longer be eligible or in good standing
                under the Exchange Act or other applicable statute, rule or
                regulation, the Company shall appoint a successor Depositary
                with respect to such Global Security or Securities. If a
                successor Depositary for such Global Security or Securities is
                not appointed by the Company within 90 days after the Company
                receives such notice or becomes aware of such ineligibility, the
                Company shall execute, and the Trustee or its agent, upon
                receipt of a Company Order for the authentication and delivery
                of such individual Debt Securities of such series in exchange
                for such Global Security, will authenticate and deliver,
                individual Debt Securities of such series of like tenor and
                terms in definitive form in an aggregate principal amount equal
                to the principal amount of the Global Security in exchange for
                such Global Security or Securities.

          (ii)  The Company may at any time and in its sole discretion determine
                that the Debt Securities of any series or portion thereof issued
                or issuable in the form of one or more Global Securities shall
                no longer be represented by such Global Security or Securities.
                In such event the Company will execute, and the Trustee, upon
                receipt of a Company Order for the authentication and delivery
                of individual Debt Securities of such series in exchange in
                whole or in part for such Global Security, will authenticate and
                deliver individual Debt Securities of such series of like tenor
                and terms in definitive form in an aggregate principal amount
                equal to the principal amount of such series or portion thereof
                in exchange for such Global Security or Securities.

          (iii) If specified by the Company pursuant to Sections 2.01 and 2.03
                with respect to Debt Securities issued or issuable in the form
                of a Global Security, the Depositary for such Global Security
                may surrender such Global Security in exchange in whole or in
                part for individual Debt Securities of such series of like tenor
                and terms in definitive form on such terms as are acceptable to
                the Company, the Trustee and such Depositary. Thereupon the
                Company shall execute, and the Trustee or its agent upon receipt
                of a Company Order for the authentication and delivery of
                definitive Debt Securities of such series shall authenticate and
                deliver, without service charge, (1) to each Person specified by
                such Depositary a new Debt Security or Securities of the same
                series of like tenor and terms and of any authorized
                denomination as requested by such Person in aggregate principal
                amount equal to and in exchange for such Person's beneficial
                interest in the Global Security; and (2) to such Depositary a
                new Global Security of like tenor and terms and in an authorized
                denomination equal to the difference, if any, between the
                principal amount of the surrendered Global Security and the
                aggregate principal amount of Debt Securities delivered to
                Holders thereof.

                                       16

          (iv)  In any exchange provided for in any of the preceding three
                paragraphs, the Company will execute and the Trustee or its
                agent will authenticate and deliver individual Debt Securities.
                Upon the exchange of the entire principal amount of a Global
                Security for individual Debt Securities, such Global Security
                shall be canceled by the Trustee or its agent. Except as
                provided in the preceding paragraph, Registered Securities
                issued in exchange for a Global Security pursuant to this
                Section 2.15 shall be registered in such names and in such
                authorized denominations as the Depositary for such Global
                Security, pursuant to instructions from its direct or indirect
                participants or otherwise, shall instruct the Trustee or the
                Registrar. The Trustee or the Registrar shall deliver such
                Registered Securities to the Persons in whose names such
                Registered Securities are so registered.

          (v)   Payments in respect of the principal of and interest on any Debt
                Securities registered in the name of the Depositary or its
                nominee will be payable to the Depositary or such nominee in its
                capacity as the registered owner of such Global Security. The
                Company and the Trustee may treat the Person in whose name the
                Debt Securities, including the Global Security, are registered
                as the owner thereof for the purpose of receiving such payments
                and for any and all other purposes whatsoever. None of the
                Company, the Trustee, any Registrar, the paying agent or any
                agent of the Company or the Trustee will have any responsibility
                or liability for (a) any aspect of the records relating to or
                payments made on account of the beneficial ownership interests
                of the Global Security by the Depositary or its nominee or any
                of the Depositary's direct or indirect participants, or for
                maintaining, supervising or reviewing any records of the
                Depositary, its nominee or any of its direct or indirect
                participants relating to the beneficial ownership interests of
                the Global Security, (b) the payments to the beneficial owners
                of the Global Security of amounts paid to the Depositary or its
                nominee, or (c) any other matter relating to the actions and
                practices of the Depositary, its nominee or any of its direct or
                indirect participants. None of the Company, the Trustee or any
                such agent will be liable for any delay by the Depositary, its
                nominee, or any of its direct or indirect participants in
                identifying the beneficial owners of the Debt Securities, and
                the Company and the Trustee may conclusively rely on, and will
                be protected in relying on, instructions from the Depositary or
                its nominee for all purposes (including with respect to the
                registration and delivery, and the respective principal amounts,
                of the Debt Securities to be issued).

SECTION 2.16. Medium Term Securities. Notwithstanding any contrary provision
herein, if all Debt Securities of a series are not to be originally issued at
one time, it shall not be necessary for the Company to deliver to the Trustee an
Officers' Certificate, resolutions of the Board of Directors, supplemental
Indenture, Opinion of Counsel or written order or any other document otherwise
required pursuant to Section 2.01, 2.03, 2.05 or 13.05 at or prior to the time
of authentication of each Debt Security of such series if such documents are
delivered to the Trustee or its agent at or prior to the authentication upon
original issuance of the first such Debt Security of such series to be issued;
provided, that any subsequent request by the Company to the Trustee to
authenticate Debt Securities of such series upon original issuance shall
constitute a representation and warranty by the Company that, as of the date of
such request, the statements made in the Officers' Certificate delivered
pursuant to Section 2.05 or 13.05 shall be true and correct as if made on such
date and that the Opinion of Counsel delivered at or prior to such time of
authentication upon original issuance of Debt Securities shall specifically
state that it shall relate to all subsequent issuances of Debt Securities of
such series that are identical to the Debt Securities issued in the first
issuance of Debt Securities of such series.

A Company Order delivered by the Company to the Trustee in the circumstances set
forth in the preceding paragraph, may provide that Debt Securities which are the
subject thereof will be authenticated and delivered by the Trustee or its agent
on original issue from time to time upon the telephonic, electronic or written
order of Persons designated in such written order (any such telephonic or
electronic instructions to be promptly confirmed in writing by such Person) and
that such Persons are authorized to determine, consistent with the Officers'
Certificate, supplemental Indenture or resolution of the Board of Directors
relating to such written order, such terms and conditions of such Debt
Securities as are specified in such Officers' Certificate, supplemental
Indenture or such resolution.

SECTION 2.17. Defaulted Interest. Any interest on any Debt Security of a
particular series which is payable, but is not punctually paid or duly provided
for, on the dates and in the manner provided in the Debt Securities of such
series and in this Indenture (herein called "Defaulted Interest") shall
forthwith cease to be payable to the Registered

                                       17

Holder thereof on the relevant record date by virtue of having been such
Registered Holder, and such Defaulted Interest may be paid by the Company, at
its election in each case, as provided in clause (i) or (ii) below:

          (i) The Company may elect to make payment of any Defaulted Interest to
          the Persons in whose names the Registered Securities of such series
          are registered at the close of business on a special record date for
          the payment of such Defaulted Interest, which shall be fixed in the
          following manner: The Company shall notify the Trustee in writing of
          the amount of Defaulted Interest proposed to be paid on each such
          Registered Security of such series and the date of the proposed
          payment, and at the same time the Company shall deposit with the
          Trustee an amount of money equal to the aggregate amount proposed to
          be paid in respect of such Defaulted Interest or shall make
          arrangements satisfactory to the Trustee for such deposit prior to the
          date of the proposed payment, such money when deposited to be held in
          trust for the benefit of the Persons entitled to such Defaulted
          Interest as in this clause provided. Thereupon the Trustee shall fix a
          special record date for the payment of such Defaulted Interest which
          shall be not more than 15 days and not less than 10 days prior to the
          date of the proposed payment and not less than 10 days after the
          receipt by the Trustee of the notice of the proposed payment. The
          Trustee shall promptly notify the Company of such special record date
          and, in the name and at the expense of the Company, shall cause notice
          of the proposed payment of such Defaulted Interest and the special
          record date therefor to be mailed, first class postage prepaid, to
          each Holder thereof at its address as it appears in the Debt 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 Registered
          Securities of such series are registered at the close of business on
          such special record date.

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


SECTION 2.18. Judgments. The Company may provide pursuant to Section 2.03 for
Debt Securities of any series that (a) the obligation, if any, of the Company to
pay the principal of, and premium, if any, and interest on, the Debt Securities
of any series in a Foreign Currency or Dollars (the "Designated Currency") as
may be specified pursuant to Section 2.03 is of the essence and agrees that, to
the fullest extent possible under applicable law, judgments in respect of Debt
Securities of such series shall be given in the Designated Currency; (b) the
obligation of the Company to make payments in the Designated Currency of the
principal of, and premium, if any, and interest on, such Debt Securities shall,
notwithstanding any payment in any other Currency (whether pursuant to a
judgment or otherwise), be discharged only to the extent of the amount in the
Designated Currency that the Holder receiving such payment may, in accordance
with normal banking procedures, purchase with the sum paid in such other
Currency (after any premium and cost exchange) on the business day in the
country of issue of the Designated Currency or in the international banking
community (in the case of a composite currency) immediately following the day on
which such Holder receives such payment; (c) if the amount in the Designated
Currency that may be so purchased for any reason falls short of the amount
originally due, the Company shall pay such additional amounts as may be
necessary to compensate for such shortfall; and (d) any obligation of the
Company not discharged by such payment shall be due as a separate and
independent obligation and, until discharged as provided herein, shall continue
in full force and effect.

                                   ARTICLE III
                          Redemption of Debt Securities

SECTION 3.01. Applicability of Article. The provisions of this Article shall be
applicable to the Debt Securities of any series which are redeemable before
their Stated Maturity except as otherwise specified as contemplated by Section
2.03 for Debt Securities of such series.

                                       18

SECTION 3.02. Notice of Redemption; Selection of Debt Securities. In case the
Company shall desire to exercise the right to redeem all or any part of the Debt
Securities of any series, as the case may be, in accordance with their terms,
the Company shall fix a date for redemption and shall give notice of such
redemption at least 30 and not more than 60 days prior to the date fixed for
redemption to the Holders of Debt Securities of such series so to be redeemed as
a whole or in part, in the manner provided in Section 13.03. The notice if given
in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives such notice. In any case, failure to
give such notice or any defect in the notice to the Holder of any Debt Security
of a series designated for redemption as a whole or in part shall not affect the
validity of the proceedings for the redemption of any other Debt Security of
such series.

Each such notice of redemption shall specify the date fixed for redemption, the
redemption price at which Debt Securities of such series are to be redeemed, the
Place or Places of Payment that payment will be made upon presentation and
surrender of such Debt Securities, that any interest accrued to the date fixed
for redemption will be paid as specified in said notice, that the redemption is
for a sinking fund payment (if applicable), that, if the Company defaults on
making such redemption payment or if the Debt Securities of that series are
subordinated pursuant to the terms of Article XII the paying agent is prohibited
from making such payment pursuant to the terms of this Indenture, that on and
after said date any interest thereon or on the portions thereof to be redeemed
will cease to accrue, that in the case of Original Issue Discount Securities
original issue discount accrued after the date fixed for redemption will cease
to accrue, the provision of the Debt Securities of that series pursuant to which
the Debt Securities of that series are being redeemed, the CUSIP numbers of the
Debt Securities of that series being redeemed and that no representation is made
as to the correctness or accuracy of the CUSIP number listed in such notice or
printed on the Debt Securities of that series. In case any Debt Security of a
series is to be redeemed in part only, the notice of redemption shall state the
portion of the principal amount thereof to be redeemed and shall state that on
and after the date fixed for redemption, upon surrender of such Debt Security, a
new Debt Security or Debt Securities of that series in principal amount equal to
the unredeemed portion thereof will be authenticated and delivered in exchange
for the unredeemed portion of the principal of the Debt Security so surrendered.

At least 60 days before the redemption date unless the Trustee consents to a
shorter period, the Company shall give notice to the Trustee of the redemption
date, the principal amount of Debt Securities to be redeemed and the series and
terms of the Debt Securities pursuant to which such redemption will occur. Such
notice shall be accompanied by an Officers' Certificate and an Opinion of
Counsel from the Company to the effect that such redemption will comply with the
conditions herein.

On or prior to the redemption date for any Registered Securities, 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) an amount of money
in the Currency in which such Debt Securities are denominated (except as
provided pursuant to Section 2.03) sufficient to pay the redemption price of
such Registered Securities or any portions thereof that are to be redeemed on
that date.

If less than all the Debt Securities of like tenor and terms of a series are to
be redeemed (other than pursuant to mandatory sinking fund redemptions), the
Trustee shall select, in such manner as in its sole discretion it shall deem
appropriate and fair, the Debt Securities of that series or portions thereof (in
authorized denominations) to be redeemed. In any case where more than one
Registered Security of such series is registered in the same name, the Trustee
in its discretion may treat the aggregate principal amount so registered as if
it were represented by one Registered Security of such series. The Trustee shall
promptly notify the Company in writing of the Debt Securities selected for
redemption and, in the case of any Debt Securities selected for partial
redemption, the principal amount thereof to be redeemed. If any Debt Security
called for redemption shall not be so paid upon surrender thereof on such
redemption date, the principal, premium, if any, and interest shall bear
interest until paid from the redemption date at the rate borne by the Debt
Securities of that series. If less than all the Debt Securities of unlike tenor
and terms of a series are to be redeemed, the particular Debt Securities to be
redeemed shall be selected by the Company. Provisions of this Indenture that
apply to Debt Securities called for redemption also apply to portions of Debt
Securities called for redemption.

SECTION 3.03. Payment of Debt Securities Called for Redemption. If notice of
redemption has been given as provided in Section 3.02, the Debt Securities or
portions of Debt Securities of the series with respect to which such

                                       19

notice has been given shall become due and payable on the date and at the Place
or Places of Payment stated in such notice at the applicable redemption price,
together with any interest accrued to the date fixed for redemption, and on and
after said date (unless the Company shall default in the payment of such Debt
Securities at the applicable redemption price, together with any interest
accrued to said date) any interest on the Debt Securities or portions of Debt
Securities of any series so called for redemption shall cease to accrue and any
original issue discount in the case of Original Issue Discount Securities shall
cease to accrue. On presentation and surrender of such Debt Securities at the
Place or Places of Payment in said notice specified, the said Debt Securities or
the specified portions thereof shall be paid and redeemed by the Company at the
applicable redemption price, together with any interest accrued thereon to the
date fixed for redemption.

Any Debt Security that is to be redeemed only in part shall be surrendered at
the corporate trust office of the Trustee or such other office or agency of the
Company as is specified pursuant to Section 2.03, with, if the Company, the
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Registrar 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 deliver to the Holder of such Debt Security without service charge, a new
Debt Security or Debt Securities of the same series, of like tenor and form, 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 Debt Security so surrendered; except that if a Global Security is so
surrendered, the Company shall execute, and the Trustee shall authenticate and
deliver to the Depositary for such Global Security, without service charge, a
new Global Security in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Global Security so surrendered. In
the case of a Debt Security providing appropriate space for such notation, at
the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt
Security or Debt Securities as aforesaid, may make a notation on such Debt
Security of the payment of the redeemed portion thereof.

SECTION 3.04. Mandatory and Optional Sinking Funds. The minimum amount of any
sinking fund payment provided for by the terms of Debt Securities of any series,
resolution of the Board of Directors or a supplemental Indenture is herein
referred to as a "mandatory sinking fund payment", and any payment in excess of
such minimum amount provided for by the terms of Debt Securities of any series,
resolution of the Board of Directors or a supplemental Indenture is herein
referred to as an "optional sinking fund payment".

In lieu of making all or any part of any mandatory sinking fund payment with
respect to any Debt Securities of a series in cash, the Company may at its
option (a) deliver to the Trustee Debt Securities of that series theretofore
purchased or otherwise acquired by the Company or (b) receive credit for the
principal amount of Debt Securities of that series which have been redeemed
either at the election of the Company pursuant to the terms of such Debt
Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Debt Securities, resolution or
supplemental Indenture; provided, that such Debt Securities have not been
previously so credited. Such Debt Securities shall be received and credited for
such purpose by the Trustee at the redemption price specified in such Debt
Securities, resolution or supplemental Indenture for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

SECTION 3.05. Redemption of Debt Securities for Sinking Fund. Not less than 60
days prior to each sinking fund payment date for any series of Debt Securities,
the Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
payment of cash in the Currency in which the Debt Securities of such series are
denominated (except as provided pursuant to Section 2.03) and the portion
thereof, if any, which is to be satisfied by delivering and crediting Debt
Securities of that series pursuant to this Section 3.05 (which Debt Securities,
if not previously redeemed, will accompany such certificate), the basis for such
credit and that such Debt Securities have not been previously so credited and
whether the Company intends to exercise its right to make any permitted optional
sinking fund payment with respect to such series. Such certificate shall also
state that no Event of Default has occurred and is continuing with respect to
such series. Such certificate shall be irrevocable and upon its delivery the
Company shall be obligated to make the cash payment or payments therein referred
to, if any, on or before the next succeeding sinking fund payment date. Failure
of the Company to deliver such certificate (or to deliver the Debt Securities
specified in this paragraph) shall not constitute a Default, but such failure
shall require that the sinking fund payment due on the next succeeding sinking
fund payment date for that series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of such Debt Securities subject to a
mandatory

                                       20

sinking fund payment without the option to deliver or credit Debt Securities as
provided in this Section 3.05 and without the right to make any optional sinking
fund payment, if any, with respect to such series.

Any sinking fund payment or payments (mandatory or optional) made in cash plus
any unused balance of any preceding sinking fund payments made in cash which
shall equal or exceed $100,000 (or a lesser sum if the Company shall so request)
with respect to the Debt Securities of any particular series shall be applied by
the Trustee on the sinking fund payment date on which such payment is made (or,
if such payment is made before a sinking fund payment date, on the sinking fund
payment date following the date of such payment) to the redemption of such Debt
Securities at the redemption price specified in such Debt Securities, resolution
or supplemental Indenture for operation of the sinking fund together with any
accrued interest to the date fixed for redemption. Any sinking fund moneys not
so applied or allocated by the Trustee to the redemption of Debt Securities
shall be added to the next cash sinking fund payment received by the Trustee for
such series and, together with such payment, shall be applied in accordance with
the provisions of this Section 3.05. Any and all sinking fund moneys with
respect to the Debt Securities of any particular series held by the Trustee on
the last sinking fund payment date with respect to Debt Securities of such
series and not held for the payment or redemption of particular Debt Securities
shall be applied by the Trustee, together with other moneys, if necessary, to be
deposited sufficient for the purpose, to the payment of the principal of the
Debt Securities of that series at its Stated Maturity.

The Trustee shall select the Debt Securities to be redeemed upon such sinking
fund payment date in the manner specified in the last paragraph of Section 3.02
and the Company shall cause notice of the redemption thereof to be given in the
manner provided in Section 3.02 except that the notice of redemption shall also
state that the Debt Securities are being redeemed by operation of the sinking
fund. Such notice having been duly given, the redemption of such Debt Securities
shall be made upon the terms and in the manner stated in Section 3.03.

At least one business day before each sinking fund payment date, the Company
shall pay to the Trustee (or, if the Company is acting as its own paying agent,
the Company shall segregate and hold in trust) in cash a sum in the Currency in
which the Debt Securities of such series are denominated (except as provided
pursuant to Section 2.03) equal to any interest accrued to the date fixed for
redemption of Debt Securities or portions thereof to be redeemed on such sinking
fund payment date pursuant to this Section 3.05.

The Trustee shall not redeem any Debt Securities of a series with sinking fund
moneys or mail any notice of redemption of such Debt Securities by operation of
the sinking fund for such series during the continuance of a Default in payment
of interest on such Debt Securities or of any Event of Default (other than an
Event of Default occurring as a consequence of this paragraph) with respect to
such Debt Securities, except that if the notice of redemption of any such Debt
Securities shall theretofore have been mailed in accordance with the provisions
hereof, the Trustee shall redeem such Debt Securities if cash sufficient for
that purpose shall be deposited with the Trustee for that purpose in accordance
with the terms of this Article III. Except as aforesaid, any moneys in the
sinking fund for such series at the time when any such Default or Event of
Default shall occur and any moneys thereafter paid into such sinking fund shall,
during the continuance of such Default or Event of Default, be held as security
for the payment of the Debt Securities of such series; provided, however, that
in case such Event of Default or Default shall have been cured or waived as
provided herein, such moneys shall thereafter be applied on the next sinking
fund payment date for such Debt Securities on which such moneys may be applied
pursuant to the provisions of this Section 3.05.

                                   ARTICLE IV
                       Particular Covenants of the Company

SECTION 4.01. Payment of Principal of, and Premium If Any, and Interest on, Debt
Securities. The Company, for the benefit of each series of Debt Securities, will
duly and punctually pay or cause to be paid the principal of, and premium, if
any, and interest on, each of the Debt Securities at the place, at the
respective times and in the manner provided herein and in the Debt Securities.
Each installment of interest on the Debt Securities may at the Company's option
be paid by mailing checks for such interest payable to the Person entitled
thereto to the address of such Person as it appears on the Debt Security
Register maintained pursuant to Section 2.07(a) or, if provided pursuant to
Section 2.03 and in accordance with arrangements satisfactory to the Trustee, at
the option of the Registered Holder by wire transfer to an account designated by
the Registered Holder.

                                       21

Principal, premium and interest of Debt Securities of any series shall be
considered paid on the date due if on such date the Trustee or any paying agent
holds in accordance with this Indenture money sufficient to pay in the Currency
in which the Debt Securities of such series are denominated (except as provided
pursuant to Section 2.03) all principal, premium and interest then due and, in
the case of Debt Securities subordinated pursuant to the terms of Article XII,
the Trustee or such paying agent, as the case may be, is not prohibited from
paying such money to the Holders on that date pursuant to the terms of the
Indenture.

The Company shall pay interest on overdue principal at the rate specified
therefor in the Debt Securities and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.


SECTION 4.02. Maintenance of Offices or Agencies for Registration of Transfer,
Exchange and Payment of Debt Securities. The Company will maintain in each Place
of Payment for any series of Debt Securities, an office or agency where Debt
Securities of such series may be presented or surrendered for payment, where
Debt Securities of such series may be surrendered for registration of transfer
or exchange and where notices and demands to or upon the Company in respect of
the Debt Securities of such series 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
presentations, surrenders, notices and demands.

The Company may also from time to time designate different or additional offices
or agencies to be maintained for such purposes (in or outside of such Place of
Payment), and may from time to time rescind any such designation; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligations described in the preceding paragraph. The company
will give prompt written notice to the Trustee of any such additional
designation or rescission of designation and any change in the location of any
such different or additional office or agency.

SECTION 4.03. Appointment to Fill a Vacancy in the Office of Trustee. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.08, a Trustee, so that there
shall at all times be a Trustee hereunder with respect to each series of Debt
Securities.

SECTION 4.04.  Duties of Paying Agents, etc.

          (a) The Company shall cause each paying agent, if any, other than the
Trustee, to execute and deliver to the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this Section 4.04,

          (i) that it will hold all sums held by it as such agent for the
          payment of the principal of, and premium, if any, or interest on, the
          Debt Securities of any series (whether such sums have been paid to it
          by the Company or by any other obligor on the Debt Securities of such
          series) in trust for the benefit of the Holders of the Debt Securities
          of such series;

          (ii) that it will give the Trustee notice of any failure by the
          Company (or by any other obligor on the Debt Securities of such
          series) to make any payment of the principal of and premium, if any,
          or interest on, the Debt Securities of such series when the same shall
          be due and payable; and

          (iii) that it will at any time during the continuance of an Event of
          Default, upon the written request of the Trustee, forthwith pay to the
          Trustee all sums so held by it as such agent.

          (b) If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of, and premium, if any, or interest, if
any, on, the Debt Securities of any series, set aside, segregate and hold in
trust for the benefit of the Holders of the Debt Securities of such series a sum
sufficient to pay such principal, premium, if any, or interest so becoming due.
The Company will promptly notify the Trustee of any failure by the Company to

                                       22

take such action or the failure by any other obligor on such Debt Securities to
make any payment of the principal of, and premium, if any, or interest on, such
Debt Securities when the same shall be due and payable.

          (c) Anything in this Section 4.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by it or any paying agent, as required by
this Section 4.04, 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.

          (d) Whenever the Company shall have one or more paying agents with
respect to any series of Debt Securities, it will, prior to each due date of the
principal of, and premium, if any, or interest on, any Debt Securities of such
series, deposit with any such paying agent a sum sufficient to pay the
principal, premium or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled thereto, and (unless any such paying agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

          (e) Anything in this Section 4.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 4.04 is subject to
the provisions of Section 11.05.

SECTION 4.05. Statement by Officers as to Default. The Company will deliver to
the Trustee, on or before a date not more than four months after the end of each
fiscal year of the Company (currently on a calendar year basis) ending after the
date hereof, an Officers' Certificate, one of the signatories of which shall be
the Company's principal executive officer, principal accounting officer or
principal financial officer, stating, as to each officer signing such
certificate, that (i) in the course of his performance of his duties as an
officer of the Company he would normally have knowledge of any Default, (ii)
whether or not to the best of his knowledge any Default occurred during such
year and (iii) if to the best of his knowledge the Company is in Default,
specifying all such Defaults and what action the Company is taking or proposes
to take with respect thereto. The Company also shall comply with Section
314(a)(4) of the Trust Indenture Act.

SECTION 4.06. Further Instruments and Acts. The Company will, upon request of
the Trustee, execute and deliver such further instruments and do such further
acts as may reasonably be necessary or proper to carry out more effectually the
purposes of this Indenture.

SECTION 4.07. Existence. Subject to Article X, the Company will do or cause to
be done all things necessary to preserve and keep in full force and effect its
existence and rights (charter and statutory); provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Company shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 4.08. Maintenance of Properties. The Company will cause all properties
used or useful in the conduct of its business or the business of any Subsidiary
to be maintained and kept in good condition, repair and working order in all
material respects and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on by the Company and
its subsidiaries may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or a
Subsidiary from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, in the judgment of the Company, not
materially detrimental to the conduct of the business of the Company and its
Subsidiaries, taken as a whole, and not disadvantageous in any material respect
to the Holders.

SECTION 4.09. Payment of Taxes and Other Claims. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Subsidiary or upon the income, profits or
property of the Company or any Subsidiary, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a Lien upon the
property of the Company or any Subsidiary, provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.

                         by the Company and the Trustee

SECTION 5.01. Company to Furnish Trustee Information as to Names and Addresses
of Holders; Preservation of Information. The Company covenants and agrees that
it will furnish or cause to be furnished to the Trustee with respect to the
Registered Securities of each series:

          (a) not more than 15 days after each record date with respect to the
          payment of interest, if any, a list, in such form as the Trustee may
          reasonably require, of the names and addresses of the Registered
          Holders as of such record date, and

          (b) at such other times as the Trustee may request in writing, within
          30 days after the receipt by the Company of any such request, a list
          as of a date not more than 15 days prior to the time such list is
          furnished;

provided, however, that so long as the Trustee shall be the Registrar, such
lists shall not be required to be furnished.

The Trustee shall preserve, in as current a form as is reasonably practicable,
all information as to the names and addresses of the Holders (1) contained in
the most recent list furnished to it as provided in this Section 5.01 or (2)
received by it in the capacity of paying agent or Registrar (if so acting)
hereunder.

The Trustee may destroy any list furnished to it as provided in this Section
5.01 upon receipt of a new list so furnished.

SECTION 5.02. Communications to Holders. Holders may communicate pursuant to
Section 312(b) of the Trust Indenture Act with other Holders with respect to
their rights under this Indenture or the Debt Securities. The Company, the
Trustee, the Registrar and anyone else shall have the protection of Section
312(c) of the Trust Indenture Act.

SECTION 5.03.  Reports by Company.

          (a) The Company covenants and agrees, and any obligor hereunder shall
covenant and agree, to file with the Trustee, within 15 days after the Company
or such obligor, as the case may be, is required to file the same with the
Securities and Exchange Commission, copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of
the foregoing as said Commission may from time to time by rules and regulations
prescribe) which the Company or such obligor, as the case may be, may be
required to file with said Commission pursuant to Section 13 or Section 15(d) of
the Exchange Act; or, if the Company or such obligor, as the case may be, is not
required to file information, documents or reports pursuant to either of such
Sections, then to file with the Trustee and said Commission, in accordance with
rules and regulations prescribed from time to time by said Commission, such of
the supplementary and periodic information, documents and reports which may be
required pursuant to Section 13 of the Exchange Act in respect of a security
listed and registered on a national securities exchange as may be prescribed
from time to time in such rules and regulations.

          (b) The Company covenants and agrees, and any obligor hereunder shall
covenant and agree, to file with the Trustee and the Securities and Exchange
Commission, in accordance with the rules and regulations prescribed from time to
time by said Commission, such additional information, documents, and reports
with respect to compliance by the Company or such obligor, as the case may be,
with the conditions and covenants provided for in this Indenture as may be
required from time to time by such rules and regulations.

SECTION 5.04. Reports by Trustee. Within 60 days after May 15 of each year
commencing with the first May 15 after the first issuance of Debt Securities
pursuant to this Indenture, the Trustee shall transmit to the Holders, in the
manner and to the extent provided in Section 313(c) of the Trust Indenture Act,
a brief report dated as of such May 15 if required by Section 313(a) of the
Trust Indenture Act.

                                       24


The Trustee shall comply with Sections 313(b) and 313(c) of the Trust Indenture
Act.

A copy of each report at the time of its mailing to Holders shall be filed with
the Securities and Exchange Commission and each stock exchange (if any) on which
the Debt Securities of any series are listed. The Company agrees to notify
promptly the Trustee whenever the Debt Securities of any series become listed on
any stock exchange and of any delisting thereof.

SECTION 5.05. Record Dates for Action by Holders. If the Company shall solicit
from the Holders of Debt Securities of any series any action (including the
making of any demand or request, the giving of any direction, notice, consent or
waiver or the taking of any other action), the Company may, at its option, by
resolution of the Board of Directors, fix in advance a record date for the
determination of Holders of Debt Securities entitled to take such action, but
the Company shall have no obligation to do so. Any such record date shall be
fixed at the Company's discretion. If such a record date is fixed, such action
may be sought or given before or after the record date, but only the Holders of
Debt Securities of record at the close of business on such record date shall be
deemed to be Holders of Debt Securities for the purpose of determining whether
Holders of the requisite proportion of Debt Securities of such series
Outstanding have authorized or agreed or consented to such action, and for that
purpose the Debt Securities of such series Outstanding shall be computed as of
such record date.

                                   ARTICLE VI
             Remedies of the Trustee and Holders in Event of Default

SECTION 6.01. Events of Default. If any one or more of the following shall have
occurred and be continuing with respect to Debt Securities of any series (each
of the following, an "Event of Default"):

          (a) default in the payment of any installment of interest upon any
          Debt Securities of that series as and when the same shall become due
          and payable, whether or not such payment shall be prohibited by
          Article XII, if applicable, and continuance of such default for a
          period of 30 days; or

          (b) default in the payment of the principal of or premium, if any, on

          upon required repurchase or otherwise, whether or not such payment
          shall be prohibited by Article XII, if applicable; or

          (c) default in the payment of any sinking fund payment with respect to
          any Debt Securities of that series as and when the same shall become
          due and payable; or

          (e) failure on the part of the Company duly to observe or perform any

          Directors authorizing the issuance of that series of Debt Securities,
          in this Indenture with respect to such series or in any supplemental
          Indenture with respect to such series (other than a covenant a default
          in the performance of which is elsewhere in this Section specifically
          dealt with), continuing for a period of 60 days after the date on
          which written notice, specifying such failure, requiring the Company
          to remedy the same and stating that such written notice is a "Notice
          of Default" hereunder, shall have been given by registered or
          certified mail to the Company by the Trustee or to the Company and the
          Trustee by the Holders of at least 25% in aggregate principal amount
          of the Debt Securities of that series at the time Outstanding; or

          (f) Indebtedness of the Company or any Subsidiary of the Company is
          not paid within any applicable grace period after final maturity or is
          accelerated by the holders thereof because of a default, the total
          amount of such Indebtedness unpaid or accelerated exceeds
          $[______________] or its Dollar Equivalent at the time and such
          default remains uncured or such acceleration is not rescinded for 10
          days after the date on which written notice specifying such failure
          and requiring the Company to remedy the same shall have been given, by
          registered or certified mail, to the Company by the Trustee

                                       25


          or to the Company and the Trustee by the Holders of at least 25% in
          aggregate principal amount of the Debt Securities of that series at
          the time Outstanding; or

          (g) the Company shall (i) voluntarily commence any proceeding or file
          any petition seeking relief under Title 11 of the United States Code
          or any other Federal or State bankruptcy, insolvency or similar law,
          (ii) consent to the institution of, or fail to controvert within the
          time and in the manner prescribed by law, any such proceeding or the
          filing of any such petition, (iii) apply for or consent to the
          appointment of a receiver, trustee, custodian, sequestrator or similar
          official for the Company or for a substantial part of its property,
          (iv) file an answer admitting the material allegations of a petition
          filed against it in any such proceeding, (v) make a general assignment
          for the benefit of creditors, (vi) admit in writing its inability or
          fail generally to pay its debts as they become due, (vii) take
          corporate action for the purpose of effecting any of the foregoing, or
          (viii) take any comparable action under any foreign laws relating to
          insolvency; or

          (h) the entry of an order or decree by a court having competent
          jurisdiction in the premises for (i) relief in respect of the Company
          or a substantial part of its property under Title 11 or the United
          States Code or any other Federal or State bankruptcy, insolvency or
          similar law, (ii) the appointment of a receiver, trustee, custodian,
          sequestrator or similar official for the Company or for a substantial
          part of its property, or (iii) the winding-up or liquidation of the
          Company; and such order or decree shall continue unstayed and in
          effect for 60 consecutive days; or any similar relief is granted under
          any foreign laws and the order or decree stays in effect for 60
          consecutive days; or

          (i) any other Event of Default provided under the terms of the Debt
          Securities of that series;

then and in each and every case that an Event of Default with respect to Debt
Securities of that series at the time outstanding occurs and is continuing,
unless the principal of and interest on all the Debt Securities of that series
shall have already become due and payable, either the Trustee or the Holders of
not less than 25% in aggregate principal amount of the Debt Securities of that
series then Outstanding hereunder, by notice in writing to the Company (and to
the Trustee if given by Holders), may declare the principal of (or, if the Debt
Securities of that series are Original Issue Discount Debt Securities, such
portion of the principal amount as may be specified in the terms of that series)
and interest on all the Debt Securities of that series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything in this Indenture or in the Debt
Securities of that series contained to the contrary notwithstanding.

The Holders of a majority in principal amount of the Debt Securities of a
particular series by notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
already rendered 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
acceleration and if the Company shall have paid or deposited with the Trustee a
sum sufficient to pay all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. Upon any such rescission, the parties hereto shall be
restored respectively to their several positions and rights hereunder, and all
rights, remedies and powers of the parties hereto shall continue as though no
proceeding had been taken.

In case the Trustee or any Holder shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee or such Holder, then and in
every such case the parties hereto shall be restored respectively to their
several positions and rights hereunder, and all rights, remedies and powers of
the parties hereto shall continue as though no such proceeding had been taken.

The foregoing Events of Default shall constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

The Company shall deliver to the Trustee, within 30 days after the occurrence
thereof, written notice in the form of an Officers' Certificate of any event
which with the giving of notice and the lapse of time would become an Event of

                                       26


Default under clause (c), (d), (e), (f), (g), (h) or (i), its status and what
action the Company is taking or proposes to take with respect thereto.

SECTION 6.02. Collection of Indebtedness by Trustee, etc. If an Event of Default
occurs and is continuing, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any action or
proceedings at law or in equity for the collection of the sums so due and unpaid
or enforce the performance of any provision of the Debt Securities of the
affected series or this Indenture, and may prosecute any such action or
proceedings to judgment or final decree, and may enforce any such judgment or
final decree against the Company or any other obligor upon the Debt Securities
of such series (and collect in the manner provided by law out of the property of
the Company or any other obligor upon the Debt Securities of such series
wherever situated the moneys adjudged or decreed to be payable).

In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor upon the Debt Securities of
any series under Title 11 of the United States Code or any other Federal or
State bankruptcy, insolvency or similar law, or in case a receiver, trustee or
other similar official shall have been appointed for its property, or in case of
any other similar judicial proceedings relative to the Company or any other
obligor upon the Debt Securities of any series, its creditors or its property,
the Trustee, irrespective of whether the principal of Debt Securities of any
series shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section 6.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal, premium, if any, and interest
(or, if the Debt Securities of such series are Original Issue Discount Debt
Securities, such portion of the principal amount as may be specified in the
terms of such series) owing and unpaid in respect of the Debt Securities of such
series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation to the Trustee, its agents, attorneys and counsel, and
for reimbursement of all expenses and liabilities Incurred, and all advances
made, by the Trustee except as a result of its negligence or bad faith) and of
the Holders thereof allowed in any such judicial proceedings relative to the
Company, or any other obligor upon the Debt Securities of such series, its
creditors or its property, and to collect and receive any moneys or other
property payable or deliverable on any such claims, and to distribute all
amounts received with respect to the claims of such Holders and of the Trustee
on their behalf, and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of such Holders to make payments to
the Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to such Holders, to pay to the Trustee such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other reasonable expenses and liabilities
Incurred, and all advances made, by the Trustee except as a result of its
negligence or bad faith.

All rights of action and of asserting claims under this Indenture, or under any
of the Debt Securities, of any series, may be enforced by the Trustee without
the possession of any such Debt Securities or the production thereof in any
trial or other proceedings relative thereto, and any such action or proceedings
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment (except for any amounts payable to
the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the
Holders of all the Debt Securities in respect of which such action was taken.

In case of an Event of Default hereunder the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

SECTION 6.03. Application of Moneys Collected by Trustee. Any moneys or other
property collected by the Trustee pursuant to Section 6.02 with respect to Debt
Securities of any series shall be applied in the order following, at the date or
dates fixed by the Trustee for the distribution of such moneys or other
property, upon presentation of the several Debt Securities of such series in
respect of which moneys or other property have been collected, and the notation
thereon of the payment, if only partially paid, and upon surrender thereof if
fully paid:

          First: To the payment of all money due the Trustee pursuant to Section
7.06;


                                       27


          Second: As provided in Article XII, if applicable;

          Third: In case the principal of the Outstanding Debt Securities in
respect of which such moneys have been collected shall not have become due, to
the payment of interest on the Debt Securities of such series in the order of
the maturity of the installments of such interest, with interest (to the extent
that such interest has been collected by the Trustee) upon the overdue
installments of interest at the rate or Yield to Maturity (in the case of
Original Issue Discount Debt Securities) borne by the Debt Securities of such
series, such payments to be made ratably to the Persons entitled thereto,
without discrimination or preference;

         Fourth: In case the principal of the Outstanding Debt Securities in
respect of which such moneys have been collected shall have become due, by
declaration or otherwise, to the payment of the whole amount then owing and
unpaid upon the Debt Securities of such series for principal and premium, if
any, and interest, with interest on the overdue principal and premium, if any,
and (to the extent that such interest has been collected by the Trustee) upon
overdue installments of interest at the rate or Yield to Maturity (in the case
of Original Issue Discount Debt Securities) borne by the Debt Securities of such
series; and, in case such moneys shall be insufficient to pay in full the whole
amount so due and unpaid upon the Debt Securities of such series, then to the
payment of such principal and premium, if any, and interest, without preference
or priority of principal and premium, if any, over interest, or of interest over
principal and premium, if any, or of any installment of interest over any other
installment of interest, or of any Debt Security of such series over any Debt
Security of such series, ratably to the aggregate of such principal and premium,
if any, and interest; and

         Fifth: The remainder, if any, shall be paid to the Company, its
successors or assigns, or to whomsoever may be lawfully entitled to receive the
same, or as a court of competent jurisdiction may direct.

The Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section 6.03. At least 15 days before such record date, the
Company shall mail to each Holder and the Trustee a notice that states the
record date, the payment date and amount to be paid.

SECTION 6.04. Limitation on Suits by Holders. No Holder of any Debt Security of
any series shall have any right by virtue or by availing of any provision of
this Indenture to institute any action or proceeding at law or in equity or in
bankruptcy or otherwise, upon or under or with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless such Holder previously shall have given to the Trustee written notice of
an Event of Default with respect to Debt Securities of that same series and of
the continuance thereof and unless the Holders of not less than 25% in aggregate
principal amount of the Outstanding Debt Securities of that series shall have
made written request upon the Trustee to institute such action or proceedings in
respect of such Event of Default in its own name as Trustee hereunder and shall
have offered to the Trustee such reasonable indemnity as it may require against
the costs, expenses and liabilities to be Incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity shall have failed to institute any such action or proceedings and no
direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 6.06; it being understood and intended, and being
expressly covenanted by the Holder of every Debt Security with every other
Holder and the Trustee, that no one or more Holders shall have any right in any
manner whatever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any Holders, or to obtain or seek to
obtain priority over or preference to any other such Holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all such Holders. For the protection and
enforcement of the provisions of this Section 6.04, each and every Holder and
the Trustee shall be entitled to such relief as can be given either at law or in
equity.

Notwithstanding any other provision in this Indenture, however, the right of any
Holder of any Debt Security to receive payment of the principal of, and premium,
if any, and (subject to Section 2.12) interest on, such Debt Security on or
after the respective due dates expressed in such Debt Security, and to institute
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or effected without the consent of such Holder.



                                       28

SECTION 6.05. Remedies Cumulative; Delay or Omission in Exercise of Rights Not a
Waiver of Default. All powers and remedies given by this Article VI to the
Trustee or to the Holders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the Holders, by judicial proceedings or otherwise,
to enforce the performance or observance of the covenants and agreements
contained in this Indenture, and no delay or omission of the Trustee or of any
Holder to exercise any right or power accruing upon any Default occurring and
continuing as aforesaid, shall impair any such right or power, or shall be
construed to be a waiver of any such Default or an acquiescence therein; and,
subject to the provisions of Section 6.04, every power and remedy given by this
Article VI or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as shall be deemed expedient, by the Trustee or by the
Holders.

SECTION 6.06. Rights of Holders of Majority in Principal Amount of Debt
Securities to Direct Trustee and to Waive Default. The Holders of a majority in
aggregate principal amount of the Debt Securities of any series at the time
Outstanding 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, with respect to the Debt Securities
of such series; provided, however, that such direction shall not be otherwise
than in accordance with law and the provisions of this Indenture, and that
subject to the provisions of Section 7.01, the Trustee shall have the right to
decline to follow any such direction if the Trustee being advised by counsel
shall determine that the action so directed may not lawfully be taken, or if the
Trustee shall by a responsible officer or officers determine that the action so
directed would involve it in personal liability or would be unjustly prejudicial
to Holders of Debt Securities of such series not taking part in such direction;
and provided further, however, that nothing in this Indenture contained shall
impair the right of the Trustee to take any action deemed proper by the Trustee
and which is not inconsistent with such direction by such Holders. The Holders
of a majority in aggregate principal amount of the Debt Securities of that
series at the time Outstanding may on behalf of the Holders of all the Debt
Securities of that series waive any past Default or Event of Default and its
consequences for that series specified in the terms thereof as contemplated by
Section 2.03, except (i) a Default in the payment of the principal of, and
premium, if any, or interest on, any of the Debt Securities and (ii) a Default
in respect of a provision that under Section 9.02 cannot be amended without the
consent of each Holder affected thereby. In case of any such waiver, such
Default shall cease to exist, any Event of Default arising there from shall be
deemed to have been cured for every purpose of this Indenture, and the Company,
the Trustee and the Holders of the Debt Securities of that series shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

SECTION 6.07. Trustee to Give Notice of Defaults Known to It, but May Withhold
Such Notice in Certain Circumstances. The Trustee shall, within 90 days after
the occurrence of a Default known to it with respect to a series of Debt
Securities give to the Holders thereof, in the manner provided in Section 13.03,
notice of all Defaults with respect to such series known to the Trustee, unless
such Defaults shall have been cured or waived before the giving of such notice;
provided that, except in the case of Default in the payment of the principal of,
or premium, if any, or interest on, any of the Debt Securities of such series or
in the making of any sinking fund payment with respect to the Debt Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a committee of
directors or responsible officers of the Trustee in good faith determine that
the withholding of such notice is in the interests of the Holders thereof.

SECTION 6.08. Requirement of an Undertaking to Pay Costs in Certain Suits under
the Indenture or Against the Trustee. All parties to this Indenture agree, and
each Holder of any Debt Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit in
the manner and to the extent provided in the Trust Indenture Act, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 6.08 shall not apply to any suit instituted
by the Trustee, to any suit instituted by any Holder, or group of Holders,
holding in the aggregate more than ten percent in principal amount of the
Outstanding Debt Securities of that series or to any suit instituted by any
Holder for the enforcement of the payment of the principal of, or premium, if
any, or interest on, any Debt Security on or after the due date for such payment
expressed in such Debt Security.


                                       29


                                   ARTICLE VII
                             Concerning the Trustee

SECTION 7.01. Certain Duties and Responsibilities. The Trustee, prior to the
occurrence of an Event of Default and after the curing or waiving of all Events
of Default which may have occurred, undertakes to perform such duties and only
such duties as are specifically set forth in this Indenture. In case an Event of
Default has occurred (which has not been cured or waived), 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 man would
exercise or use under the circumstances in the conduct of his own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own negligent failure to act, or its
own willful misconduct, except that:

          (a) this subsection shall not be construed to limit the effect of the
          first paragraph of this Section 7.01;

          (b) prior to the occurrence of an Event of Default with respect to the
          Debt Securities of a series and after the curing or waiving of all
          Events of Default with respect to such series which may have occurred:

          (1) the duties and obligations of the Trustee with respect to Debt
          Securities of such series shall be determined solely by the express
          provisions of this Indenture, and the Trustee shall not be liable
          except for the performance of such duties and obligations with respect
          to such series as are specifically set forth in this Indenture, and no
          implied covenants or obligations with respect to such series shall be
          read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on the part of the Trustee, the
          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 Trustee and conforming to
          the requirements of this Indenture; but in the case of any such
          certificates or opinions which by any provision hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture; but the Trustee
          shall examine the evidence furnished to it pursuant to Section 5.03 to
          determine whether or not such evidence conforms to the requirement of
          this Indenture;

          (c) the Trustee shall not be liable for an error of judgment made in
          good faith by a responsible officer, unless it shall be proved that
          the Trustee was negligent in ascertaining the pertinent facts;

          (d) the Trustee shall not be liable with respect to any action taken
          or omitted to be taken by it with respect to Debt Securities of any
          series in good faith in accordance with the direction of the Holders
          of not less than a majority in aggregate principal amount of the
          Outstanding Debt Securities of that series relating to the time,
          method and place of conducting any proceeding for any remedy available
          to the Trustee, or exercising any trust or power conferred upon the
          Trustee, under this Indenture with respect to Debt Securities of such
          series; and

          (e) none of the provisions of this Indenture shall require the Trustee
          to expend or risk its own funds or otherwise incur any personal
          financial liability in the performance of any of its duties hereunder,
          or in the exercise of any of its rights or powers, if there shall be
          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 7.02.  Certain Rights of Trustee.  Except as otherwise provided
in Section 7.01:

          (a) the Trustee may rely and shall be protected in acting or
          refraining from acting upon any resolution, certificate, statement,
          instrument, opinion, report, notice, request, direction, consent,
          order, bond,

                                       30

          debenture, note 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, direction, order or demand of the Company mentioned
          herein shall be sufficiently evidenced by a Company Order (unless
          other evidence in respect thereof be herein specifically prescribed);
          and any resolution of the Board of Directors may be evidenced to the
          Trustee by a copy thereof certified by the Secretary or an Assistant
          Secretary of the Company;

          (c) the Trustee may consult with counsel, and the advice of such
          counsel or any Opinion of Counsel shall be full and complete
          authorization and protection in respect of any action taken or
          suffered or omitted by it hereunder in good faith and in accordance
          with such advice or Opinion of Counsel;

          (d) the Trustee shall be under no obligation to exercise any of the
          rights or powers vested in it by this Indenture at the request, order
          or direction of any of the Holders of Debt Securities of any series
          pursuant to the provisions of this Indenture, unless such Holders
          shall have offered to the Trustee reasonable security or indemnity
          against the costs, expenses and liabilities which may be Incurred
          therein or thereby;

          (e) the Trustee shall not be liable for any action taken or omitted by
          it in good faith and reasonably believed by it to be authorized or
          within the discretion or rights or powers conferred upon it by this
          Indenture;

          (f) prior to the occurrence of an Event of Default and after the
          curing or waiving of all Events of Default which may have occurred,
          the Trustee shall not be bound to make any investigation into the
          facts or matters stated in any resolution, certificate, statement,
          instrument, opinion, report, notice, request, direction, consent,
          order, approval or other paper or document, unless requested in
          writing to do so by the Holders of a majority in aggregate principal
          amount of the then outstanding Debt Securities of a series affected by
          such matter; provided, however, that if the payment within a
          reasonable time to the Trustee of the costs, expenses or liabilities
          likely to be Incurred by it in the making of such investigation is
          not, in the opinion of the Trustee, reasonably assured to the Trustee
          by the security afforded to it by the terms of this Indenture, the
          Trustee may require reasonable indemnity against such costs, expenses
          or liabilities as a condition to so proceeding. The reasonable expense
          of every such investigation shall be paid by the Company or, if paid
          by the Trustee, shall be repaid by the Company upon demand;

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

          (h) if any property other then cash shall at any time be subject to a
          Lien in favor of the Holders, the Trustee, if and to the extent
          authorized by a receivership or bankruptcy court of competent
          jurisdiction or by the supplemental instrument subjecting such
          property to such Lien, shall be entitled to make advances for the
          purpose of preserving such property or of discharging tax Liens or
          other prior Liens or encumbrances thereon.

SECTION 7.03. Trustee Not Liable for Recitals in Indenture or in Debt
Securities. The recitals contained herein and in the Debt Securities (except the
Trustee's certificate of authentication) shall be taken as the statements of the
Company, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations as to the validity or sufficiency of
this Indenture or of the Debt Securities of any series, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Debt Securities and perform its obligations hereunder, and that
the statements made by it or to be made by it in a Statement of Eligibility and
Qualification on Form T-1 supplied to the Company are true and accurate. The
Trustee shall not be accountable for the use or application by the Company of
any of the Debt Securities or of the proceeds thereof. The Trustee shall not be
charged with knowledge of any Default or Event of Default hereunder unless an
officer of the Trustee assigned to and working in its corporate trust office
shall have actual knowledge thereof or unless notice thereof shall have been
given to the Trustee in accordance with Section 13.03 by the Company or any
Holder.

                                       31


SECTION 7.04. Trustee, Paying Agent or Registrar May Own Debt Securities. The
Trustee or any paying agent or Registrar, in its individual or any other
capacity, may become the owner or pledgee of Debt Securities and subject to the
provisions of the Trust Indenture Act relating to conflicts of interest and
preferential claims may otherwise deal with the Company with the same rights it
would have if it were not Trustee, paying agent or Registrar.

SECTION 7.05. Moneys Received by Trustee to Be Held in Trust. Subject to the
provisions of Section 11.05, all moneys received by the Trustee shall, until
used or applied as herein provided, be held in trust for the purposes for which
they were received, but need not be segregated from other funds except to the
extent required by law. The Trustee shall be under no liability for interest on
any moneys received by it hereunder. So long as no Event of Default shall have
occurred and be continuing, all interest allowed on any such moneys shall be
paid from time to time to the Company upon a Company Order.

SECTION 7.06. Compensation and Reimbursement. The Company covenants and agrees
to pay in Dollars to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation for all services rendered by it hereunder
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and, except as otherwise
expressly provided herein, the Company will pay or reimburse in Dollars the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents, attorneys and counsel and of all Persons not
regularly in its employ) except any such expense, disbursement or advances as
may arise from its negligence or bad faith. The Company also covenants to
indemnify in Dollars the Trustee for, and to hold it harmless against, any loss,
liability or expense Incurred without negligence, willful misconduct or bad
faith on the part of the Trustee, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder, including the
reasonable costs and expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of its powers or duties
hereunder. The obligations of the Company under this Section 7.06 to compensate
and indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the satisfaction and discharge of this Indenture. The Company
and the Holders agree that such additional indebtedness shall be secured by a
Lien prior to that of the Debt Securities upon all property and funds held or
collected by the Trustee, as such, except funds held in trust for the payment of
principal of, and premium, if any, or interest on, particular Debt Securities.

Without prejudice to any other rights available to the Trustee under applicable
law, when the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency, reorganization or other similar
law.

SECTION 7.07. Right of Trustee to Rely on an Officers' Certificate Where No
Other Evidence Specifically Prescribed. Except as otherwise provided in Section
7.01, whenever in the administration of the provisions of this Indenture the
Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or suffering or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the
Trustee, be deemed to be conclusively proved and established by an Officers'
Certificate delivered to the Trustee and such certificate, in the absence of
negligence or bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken, suffered or omitted by it under the provisions of
this Indenture upon the faith thereof.

SECTION 7.08. Separate Trustee; Replacement of Trustee. The Company may, but
need not, appoint a separate Trustee for any one or more series of Debt
Securities. The Trustee may resign with respect to one or more or all series of
Debt Securities at any time by giving notice to the Company. The Holders of a
majority in principal amount of the Debt Securities of a particular series may
remove the Trustee for such series and only such series by so notifying the
Trustee and may appoint a successor Trustee. The Company shall remove the
Trustee if:

          (1) the Trustee fails to comply with Section 7.10;

          (2) the Trustee is adjudged bankrupt or insolvent;

                                       32

          (3) a receiver or other public officer takes charge of the Trustee or
          its property; or

          (4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns, is removed by the Company or by the Holders of a
majority in principal amount of the Debt Securities of a particular series and
(where so removed by such Holders) such Holders do not reasonably promptly
appoint a successor Trustee, or if a vacancy exists in the office of Trustee for
any reason (the Trustee in such event being referred to herein as the retiring
Trustee), the Company shall promptly appoint a successor Trustee. No resignation
or removal of the Trustee and no appointment of a successor Trustee shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of this Section 7.08.

A successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Thereupon the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee shall have
all the rights, powers and duties of the Trustee under this Indenture. The
successor Trustee shall mail a notice of its succession to Holders of Debt
Securities of each applicable series. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject to
the Lien provided for in Section 7.06.

If a successor Trustee does not take office within 60 days after the retiring
Trustee gives notice of resignation or is removed, the retiring Trustee or the
Holders of 25% in principal amount of the Debt Securities of any applicable
series may petition any court of competent jurisdiction for the appointment of a
successor Trustee for the Debt Securities of such series.

If the Trustee fails to comply with Section 7.10, any Holder of Debt Securities
of any applicable series who has been a bona fide Holder of such Debt Securities
for at least six months may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee for the Debt
Securities of such series.

Notwithstanding the replacement of the Trustee pursuant to this Section 7.08,
the Company's obligations under Section 7.06 shall continue for the benefit of
the retiring Trustee.

In the case of the appointment hereunder of a separate or successor trustee with
respect to the Debt Securities of one or more but not all series, the Company,
any retiring Trustee and each successor or separate Trustee with respect to the
Debt Securities of any applicable series shall execute and deliver an Indenture
supplemental hereto (1) which shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties
of any retiring Trustee with respect to the Debt Securities of any series as to
which any such retiring Trustee is not retiring shall continue to be vested in
such retiring Trustee and (2) that shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one trustee, it being
understood that nothing herein or in such supplemental Indenture shall
constitute such Trustees co-trustees of the same trust and that each such
separate, retiring or successor Trustee shall be Trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee.

SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all of its corporate
trust business or assets to, another corporation or banking association, the
resulting, surviving or transferee corporation or banking association without
any further act shall be the successor Trustee; provided, that it is qualified
and eligible hereunder.

In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Debt Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Debt Securities so
authenticated; and in case at that time any of the Debt Securities shall not
have been authenticated, any successor to the Trustee may authenticate such Debt
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Debt Securities or in this Indenture
provided that the certificate of the Trustee shall have.


                                       33


SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times
satisfy the requirements of Section 310(a) of the Trust Indenture Act. The
Trustee shall have a combined capital and surplus of at least $50,000,000, as
set forth in its most recent published annual report of condition. No obligor
upon the Debt Securities of a particular series or Person directly or indirectly
controlling, controlled by or under common control with such obligor shall serve
as Trustee upon the Debt Securities of such series. The Trustee shall comply
with Section 310(b) of the Trust Indenture Act, subject to the penultimate
paragraph thereof; provided, however, that there shall be excluded from the
operation of Section 310(b)(1) of the Trust Indenture Act this Indenture or any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in Section 310(b)(1) of the Trust
Indenture Act are met.

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee
shall comply with Section 311(a) of the Trust Indenture Act, excluding any
creditor relationship listed in Section 311(b) of the Trust Indenture Act. A
Trustee who had resigned or been removed shall be subject to Section 311(a) of
the Trust Indenture Act to the extent indicated therein.

SECTION 7.12. Compliance with Tax Laws. The Trustee hereby agrees to comply with
all U.S. Federal income tax information reporting and withholding requirements
applicable to it with respect to payments of premium (if any) and interest on
the Debt Securities, whether acting as Trustee, Security Registrar, paying agent
or otherwise with respect to the Debt Securities.

                                  ARTICLE VIII
                             Concerning the Holders

SECTION 8.01. Evidence of Action by Holders. Whenever in this Indenture it is
provided that the Holders of a specified percentage in aggregate principal
amount of the Debt Securities of any or all series may take action (including
the making of any demand or request, the giving of any direction, notice,
consent or waiver or the taking of any other action) the fact that at the time
of taking any such action the Holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of
similar tenor executed by Holders in person or by agent or proxy appointed in
writing, (b) by the record of the Holders voting in favor thereof at any meeting
of Holders duly called and held in accordance with the provisions of Section
13.09 or (c) by a combination of such instrument or instruments and any such
record of such a meeting of Holders.

SECTION 8.02. Proof of Execution of Instruments and of Holding of Debt
Securities. Subject to the provisions of Sections 7.01, 7.02 and 13.09, proof of
the execution of any instrument by a Holder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee.

The ownership of Registered Securities of any series shall be proved by the Debt
Security Register or by a certificate of the Registrar for such series.

The Trustee may require such additional proof of any matter referred to in this
Section 8.02 as it shall deem necessary.

SECTION 8.03. Who May Be Deemed Owner of Debt Securities. Prior to due
presentment for registration of transfer of any Registered Security, the
Company, the Trustee, any paying agent and any Registrar may deem and treat the
Person in whose name any Registered Security shall be registered upon the books
of the Company as the absolute owner of such Registered Security (whether or not
such Registered Security shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of or
on account of the principal of and premium, if any, and (subject to Sections
2.12 and 2.17) interest on such Registered Security and for all other purposes,
and neither the Company nor the Trustee nor any paying agent nor any Registrar
shall be affected by any notice to the contrary; and all such payments so made
to any such Holder for the time being, or upon his order, shall be valid and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Registered Security.



                                       34


None of the Company, the Trustee, any paying agent or the Registrar will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

SECTION 8.04. Instruments Executed by Holders Bind Future Holders. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
8.01, of the taking of any action by the Holders of the percentage in aggregate
principal amount of the Debt Securities of any series specified in this
Indenture in connection with such action and subject to the following paragraph,
any Holder of a Debt Security which is shown by the evidence to be included in
the Debt Securities the Holders of which have consented to such action may, by
filing written notice with the Trustee at its corporate trust office and upon
proof of holding as provided in Section 8.02, revoke such action so far as
concerns such Debt Security. Except as aforesaid any such action taken by the
Holder of any Debt Security shall be conclusive and binding upon such Holder and
upon all future Holders and owners of such Debt Security and of any Debt
Security issued upon registration of transfer thereof or in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon such Debt Security or such other Debt Securities. Any
action taken by the Holders of the percentage in aggregate principal amount of
the Debt Securities of any series specified in this Indenture in connection with
such action shall be conclusively binding upon the Company, the Trustee and the
Holders of all the Debt Securities of such series.

The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders of Registered Securities entitled to give
their consent or take any other action required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders of Registered
Securities at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders of Registered Securities after such record date. No such
consent shall be valid or effective for more than 120 days after such record
date unless the consent of the Holders of the percentage in aggregate principal
amount of the Debt Securities of such series specified in this Indenture shall
have been received within such 120-day period.

                                   ARTICLE IX
                             Supplemental Indentures

SECTION 9.01. Purposes for Which Supplemental Indenture May Be Entered into
Without Consent of Holders. The Company, when authorized by a resolution of the
Board of Directors, and the Trustee may from time to time and at any time,
without the consent of Holders, enter into an Indenture or Indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as in force at the date of the execution thereof) for one or more
of the following purposes:

          (a) to evidence the succession pursuant to Article X of another Person
          to the Company, or successive successions, and the assumption by the
          Successor Company (as defined in Section 10.01) of the covenants,
          agreements and obligations of the Company in this Indenture and in the
          Debt Securities;

          (b) to surrender any right or power herein conferred upon the Company,
          to add to the covenants of the Company such further covenants,
          restrictions, conditions or provisions for the protection of the
          Holders of all or any series of Debt Securities (and if such covenants
          are to be for the benefit of less than all series of Debt Securities,
          stating that such covenants are expressly being included solely for
          the benefit of such series) as the Board of Directors shall consider
          to be for the protection of the Holders of such Debt Securities, and
          to make the occurrence, or the occurrence and continuance, of a
          default in any of such additional covenants, restrictions, conditions
          or provisions a Default or an Event of Default permitting the
          enforcement of all or any of the several remedies provided in this
          Indenture; provided, that in respect of any such additional covenant,
          restriction, condition or provision such supplemental Indenture may
          provide for a particular period of grace after Default (which period
          may be shorter or longer than that allowed in the case of other
          Defaults) or may provide for an immediate enforcement upon such
          Default or may limit the remedies available to the Trustee upon such
          Default or may limit the right of the Holders of a majority in
          aggregate principal amount of any or all series of Debt Securities to
          waive such default;

                                       35


          (c) to cure any ambiguity or to correct or supplement any provision
          contained herein, in any supplemental Indenture or in any Debt
          Securities of any series that may be defective or inconsistent with
          any other provision contained herein, in any supplemental Indenture or
          in the Debt Securities of such series; to convey, transfer, assign,
          mortgage or pledge any property to or with the Trustee, or to make
          such other provisions in regard to matters or questions arising under
          this Indenture as shall not adversely affect the interests of any
          Holders of Debt Securities of any series;

          (d) to modify or amend this Indenture in such a manner as to permit
          the qualification of this Indenture or any Indenture supplemental
          hereto under the Trust Indenture Act as then in effect, except that
          nothing herein contained shall permit or authorize the inclusion in
          any Indenture supplemental hereto of the provisions referred to in
          Section 316(a)(2) of the Trust Indenture Act;

          (e) to add to or change any of the provisions of this Indenture to
          change or eliminate any restrictions on the payment of principal of,
          or premium, if any, or interest on, Registered Securities; provided,
          that any such action shall not adversely affect the interests of the
          Holders of Debt Securities of any series in any material respect; or
          permit or facilitate the issuance of Debt Securities of any series in
          uncertificated form;

          (f) in the case of any Debt Securities, if any, subordinated pursuant
          to Article XII, to make any change in Article XII that would limit or
          terminate the benefits applicable to any holder of Senior Indebtedness
          (or Representatives therefor) under Article XII;

          (g) to add Guarantees with respect to the Debt Securities or to secure
          the Debt Securities;

          (h) to add to, change or eliminate any of the provisions of this
          Indenture in respect of one or more series of Debt Securities;
          provided, however, that any such addition, change or elimination not
          otherwise permitted under this Section 9.01 shall (i) neither (A)
          apply to any Debt Security of any series created prior to the
          execution of such supplemental Indenture and entitled to the benefit
          of such provision nor (B) modify the rights of the Holder of any such
          Debt Security with respect to such provision or (ii) shall become
          effective only when there is no such Debt Security outstanding;

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

          (j) to establish the form or terms of Debt Securities of any series as
          permitted by Sections 2.01 and 2.03.

The Trustee is hereby authorized to join with the Company in the execution of
any such supplemental Indenture, to make any further appropriate agreements and
stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental Indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

Any supplemental Indenture authorized by the provisions of this Section 9.01 may
be executed by the Company and the Trustee without the consent of the Holders of
any of the Debt Securities at the time outstanding, notwithstanding any of the
provisions of Section 9.02.

In the case of any Debt Securities subordinated pursuant to Article XII, an
amendment under this Section 9.01 may not make any change that adversely affects
the rights under Article XII of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
Representative thereof authorized to give a consent) consent to such change.

After an amendment under this Section 9.01 becomes effective, the Company shall
mail to Holders of Debt Securities of each series affected thereby a notice
briefly describing such amendment. The failure to give such

                                       36


notice to all such Holders, or any defect therein, shall not impair or affect
the validity of an amendment under this Section 9.01.


SECTION 9.02. Modification of Indenture with Consent of Holders of Debt
Securities. Without notice to any Holder but with the consent (evidenced as
provided in Section 8.01) of the Holders of not less than a majority in
aggregate principal amount of the outstanding Debt Securities of each series
affected by such supplemental Indenture, the Company, when authorized by a
resolution of the Board of Directors, and the Trustee may from time to time and
at any time enter into an Indenture or Indentures supplemental hereto (which
shall conform to the provisions of the Trust Indenture Act as in force at the
date of execution thereof) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental Indenture or of modifying in any manner the rights of the
Holders of the Debt Securities of such series; provided, that no such
supplemental Indenture, without the consent of the Holders of each Debt Security
so affected, shall (i) reduce the percentage in principal amount of Debt
Securities of any series whose Holders must consent to an amendment; (ii) reduce
the rate of or extend the time for payment of interest on any Debt Security;
(iii) reduce the principal of or extend the Stated Maturity of any Debt
Security; (iv) reduce the premium payable upon the redemption of any Debt
Security or change the time at which any Debt Security may or shall be redeemed
in accordance with Article III; (v) make any Debt Security payable in Currency
other than that stated in the Debt Security; (vi) in the case of any Debt
Security subordinated pursuant to Article XII, make any change in Article XII
that adversely affects the rights of any Holder under Article XII; (vii) release
any security that may have been granted in respect of the Debt Securities; or
(viii) make any change in Section 6.06 or this Section 9.02.

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

Upon the request of the Company, accompanied by a copy of a resolution of the
Board of Directors authorizing the execution of any such supplemental Indenture,
and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental Indenture unless such supplemental Indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion but shall not be obligated to enter into
such supplemental Indenture.

It shall not be necessary for the consent of the Holders under this Section 9.02
to approve the particular form of any proposed supplemental Indenture, but it
shall be sufficient if such consent shall approve the substance thereof.

In the case of any Debt Securities subordinated pursuant to Article XII, an
amendment under this Section 9.02 may not make any change that adversely affects
the rights under Article XII of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
Representative thereof authorized to give a consent) consent to such change.

After an amendment under this Section 9.02 becomes effective, the Company shall
mail to Holders of Debt Securities of each series affected thereby a notice
briefly describing such amendment. The failure to give such notice to all such
Holders, or any defect therein, shall not impair or affect the validity of an
amendment under this Section 9.02.

SECTION 9.03. Effect of Supplemental Indentures. Upon the execution of any
supplemental Indenture pursuant to the provisions of this Article IX, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Company and the Holders
shall thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental Indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.




                                       37


The Trustee, subject to the provisions of Sections 7.01 and 7.02, may receive an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that any
such supplemental Indenture complies with the provisions of this Article IX.


SECTION 9.04. Debt Securities May Bear Notation of Changes by Supplemental
Indentures. Debt Securities of any series authenticated and delivered after the
execution of any supplemental Indenture pursuant to the provisions of this
Article IX may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
Indenture. New Debt Securities of any series so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental Indenture may be prepared and
executed by the Company, authenticated by the Trustee and delivered in exchange
for the Debt Securities of such series then outstanding. Failure to make the
appropriate notation or to issue a new Debt Security of such series shall not
affect the validity of such amendment.

SECTION 9.05. Payment for Consent. Neither the Company nor any Affiliate of the
Company shall, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest fee or otherwise, to any Holder for or
as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Debt Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                    ARTICLE X
                    Consolidation, Merger, Sale or Conveyance

SECTION 10.01. Consolidations and Mergers of the Company. The Company shall not
consolidate with or merge with or into any Person, or convey, transfer or lease
all or substantially all its assets to any Person, unless: (i) either (a) the
Company shall be the continuing Person in the case of a merger or (b) the
resulting, surviving or transferee Person if other than the Company (the
"Successor Company") shall be a corporation organized and existing under the
laws of the United States, any State thereof or the District of Columbia and the
Successor Company shall expressly assume, by an Indenture supplemental hereto,
executed and delivered to the Trustee, in form satisfactory to the Trustee, all
the obligations of the Company under the Debt Securities according to their
tenor, and this Indenture; (ii) immediately after giving effect to such
transaction (and treating any Indebtedness which becomes an obligation of the
Successor Company or any Subsidiary of the Company as a result of such
transaction as having been Incurred by the Successor Company or such Subsidiary
at the time of such transaction), no Default or Event of Default would occur or
be continuing; and (iii) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and such supplemental
Indenture (if any) comply with this Indenture.

SECTION 10.02. Rights and Duties of Successor Corporation. In case of any
consolidation, merger, conveyance, transfer or lease of the assets of the
Company in accordance with Section 10.01, the Successor Company shall succeed to
and be substituted for the Company, with the same effect as if it had been named
herein as the party of the first part, and the predecessor corporation (except
in the case of a lease) shall be relieved of any further obligation under the
Indenture and the Debt Securities. The Successor Company thereupon may cause to
be signed, and may issue either in its own name or in the name of the Company,
any or all the Debt Securities issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee; and, upon the
order of the Successor Company, instead of the Company, and subject to all the
terms, conditions and limitations in this Indenture prescribed, the Trustee
shall authenticate and shall deliver any Debt Securities which previously shall
have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Debt Securities which the Successor Company thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All the
Debt Securities so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Debt Securities theretofore or thereafter
issued in accordance with the terms of this Indenture as though all such Debt
Securities had been issued at the date of the execution hereof.

In case of any such consolidation, merger, conveyance, transfer or lease, such
changes in phraseology and form (but not in substance) may be made in the Debt
Securities appertaining thereto thereafter to be issued as may be appropriate.

                                   ARTICLE XI
                    Satisfaction and Discharge of Indenture;
                          Defeasance; Unclaimed Moneys

SECTION 11.01. Applicability of Article. The provisions of this Article XI
relating to defeasance of Debt Securities shall be applicable to the Debt
Securities of a series except as otherwise specified pursuant to Section 2.03
for the Debt Securities of such series.

SECTION 11.02.  Satisfaction and Discharge of Indenture; Defeasance.
- -------------------------------------------------------------------

          (a) If at any time (i) the Company shall have delivered to the Trustee
for cancellation all Debt Securities of any series theretofore authenticated and
delivered (other than (1) any Debt Securities of such series which shall have
been destroyed, lost or stolen and which shall have been replaced or paid as
provided in Section 2.09 and (2) Debt Securities for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Company as
provided in Section 11.05) or (ii) all Debt Securities of such series not
theretofore delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee as trust funds the entire amount in the Currency in
which such Debt Securities are denominated (except as otherwise provided
pursuant to Section 2.03) sufficient to pay at maturity or upon redemption all
Debt Securities of such series not theretofore delivered to the Trustee for
cancellation, including principal and premium, if any, and interest due or to
become due on such date of maturity or redemption date, as the case may be, and
if in either case the Company shall also pay or cause to be paid all other sums
payable hereunder by the Company, then this Indenture shall cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of such Debt Securities herein expressly provided for and rights to
receive payments of principal of, and premium, if any, and interest on, such
Debt Securities) with respect to the Debt Securities of such series, and the
Trustee, on demand of the Company accompanied by an Officers' Certificate and an
Opinion of Counsel complying with Section 13.05 and at the cost and expense of
the Company, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture.

          (b) Subject to Sections 11.02(c), 11.03 and 11.07, the Company at any
time may terminate, with respect to Debt Securities of a particular series, (i)
all its obligations under the Debt Securities of such series and this Indenture
with respect to the Debt Securities of such series ("legal defeasance option")
or (ii) its obligations with respect to the Debt Securities of such series under
clause (ii) of Section 10.01 and the related operation of Section 6.01(d), any
obligations with respect to the Debt Securities of such series which, in
accordance with Section 2.03(12), are subject to the covenant defeasance option,
and the related operation of Section 6.01(e), and the operation of Sections 6.01
(f) and (i) ("covenant defeasance option"). The Company may exercise its legal
defeasance option notwithstanding its prior exercise of its covenant defeasance
option.

If the Company exercises its legal defeasance option, payment of the Debt
Securities of the defeased series may not be accelerated because of an Event of
Default. If the Company exercises its covenant defeasance option, payment of the
Debt Securities of the defeased series may not be accelerated because of an
Event of Default specified in Sections 6.01(d), (e), (f) and (i) (except to the
extent covenants or agreements referenced in such Sections remain applicable).

Upon satisfaction of the conditions set forth herein and upon request of the
Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c) Notwithstanding clauses (a) and (b)(i) above, the Company's
obligations in Sections 2.07, 2.09, 4.02, 4.03, 4.04, 5.01, 7.06, 11.06 and
11.07 shall survive until the Debt Securities of the defeased series have been
paid in full. Thereafter, the Company's obligations in Sections 7.06 and 11.06
shall survive.

SECTION 11.03. Conditions of Defeasance. The Company may exercise its legal
defeasance option or its covenant defeasance option with respect to Debt
Securities of a particular series only if:


                                       39


          (1) the Company irrevocably deposits in trust with the Trustee money
          or U.S. Government Obligations for the payment of principal of, and
          premium, if any, and interest on, the Debt Securities of such series
          to maturity or redemption, as the case may be;

          (2) the Company delivers to the Trustee a certificate from a
          nationally recognized firm of independent accountants expressing their
          opinion that the payments of principal and interest when due and
          without reinvestment on the deposited U.S. Government Obligations plus
          any deposited money without investment will provide cash at such times
          and in such amounts as will be sufficient to pay the principal,
          premium and interest when due on all the Debt Securities of such
          series to maturity or redemption, as the case may be;

          (3) 91 days pass after the deposit is made and during the 91-day
          period no Default specified in Section 6.01(g) or (h) with respect to
          the Company occurs which is continuing at the end of the period;

          (4) no Default has occurred and is continuing on the date of such
          deposit and after giving effect thereto;

          (5) the deposit does not constitute a default under any other
          agreement binding on the Company and, if the Debt Securities of such
          series are subordinated pursuant to Article XII, is not prohibited by
          Article XII;

          (6) the Company delivers to the Trustee an Opinion of Counsel to the
          effect that the trust resulting from the deposit does not constitute,
          or is qualified as, a regulated investment company under the
          Investment Company Act of 1940;

          (7) in the event of the legal defeasance option, the Company shall
          have delivered to the Trustee an Opinion of Counsel stating that (i)
          the Company has received from the Internal Revenue Service a ruling,
          or (ii) since the date of this Indenture there has been a change in
          the applicable Federal income tax law, in either case of the effect
          that, and based thereon such Opinion of Counsel shall confirm that,
          the Holders of Debt Securities of such series will not recognize
          income, gain or loss for Federal income tax purposes as a result of
          such defeasance and will be subject to Federal income tax on the same
          amounts, in the same manner and at the same times as would have been
          the case if such defeasance had not occurred;

          (8) in the event of the covenant defeasance option, the Company shall
          have delivered to the Trustee an Opinion of Counsel to the effect that
          the Holders of Debt Securities of such series will not recognize
          income, gain or loss for Federal income tax purposes as a result of
          such covenant defeasance and will be subject to Federal income tax on
          the same amounts, in the same manner and at the same times as would
          have been the case if such covenant defeasance had not occurred; and

          (9) the Company delivers to the Trustee an Officers' Certificate and
          an Opinion of Counsel, each stating that all conditions precedent to
          the defeasance and discharge of the Debt Securities of such series as
          contemplated by this Article XI have been complied with.

Before or after a deposit, the Company may make arrangements satisfactory to the
Trustee for the redemption of Debt Securities of such series at a future date in
accordance with Article III.

SECTION 11.04. Application of Trust Money. The Trustee shall hold in trust money
or U.S. Government Obligations deposited with it pursuant to this Article XI. It
shall apply the deposited money and the money from U.S. Government Obligations
through any paying agent and in accordance with this Indenture to the payment of
principal of, and premium, if any, and interest on, the Debt Securities of the
defeased series. In the event the Debt Securities of the defeased series or the
Debt Securities of a series with respect to which the Indenture has been
discharged are subordinated pursuant to Article XII, money and securities so
held in trust are not subject to Article XII.

SECTION 11.05. Repayment to Company. The Trustee and any paying agent shall
promptly turn over to the Company upon request any excess money or securities
held by them at any time; provided, that, if such excess

                                       40


money or securities are held by the Trustee in connection with the exercise by
the Company of the legal defeasance option or the covenant defeasance option,
the Trustee shall not turn over such excess money or securities unless it shall
have received a certificate from a nationally recognized firm of independent
accountants to the effect that such money and securities are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent defeasance in accordance with Section 11.03.

Subject to any applicable abandoned property law, the Trustee and any paying
agent shall pay to the Company upon request any money held by them for the
payment of principal, premium or interest that remains unclaimed for two years,
and, thereupon, all liability of the Trustee and any such paying agent with
respect to such money shall cease, and, thereafter, Holders entitled to such
money must look to the Company for payment as general creditors.

SECTION 11.06. Indemnity for U.S. Government Obligations. The Company shall pay
and shall indemnify the Trustee and the Holders against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or
the principal and interest received on such U.S. Government Obligations.

SECTION 11.07. Reinstatement. If the Trustee or any paying agent is unable to
apply any money or U.S. Government Obligations in accordance with this Article
XI by reason of any legal proceeding or by reason of any order or judgment of
any court or government authority enjoining, restraining or otherwise
prohibiting such application, the Company's obligations under this Indenture and
the Debt Securities of the defeased series shall be revived and reinstated as
though no deposit had occurred pursuant to this Article XI until such time as
the Trustee or any paying agent is permitted to apply all such money or U.S.
Government Obligations in accordance with this Article XI; provided, however,
that if the Company makes any payment of principal of, premium, if any, or
interest on any such Debt Security following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Debt Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or such paying agent.

                                   ARTICLE XII
                        Subordination of Debt Securities

SECTION 12.01. Applicability of Article; Agreement to Subordinate. The
provisions of this Article XII shall be applicable to the Debt Securities of any
series (Debt Securities of such series referred to in this Article XII as
"Subordinated Debt Securities") designated, pursuant to Section 2.03, as
subordinated to Senior Indebtedness. Each Holder by accepting a Subordinated
Debt Security agrees that the Indebtedness evidenced by such Subordinated Debt
Security is subordinated in right of payment, to the extent and in the manner
provided in this Article XII, to the prior payment of all Senior Indebtedness
and that the subordination is for the benefit of and enforceable by the holders
of Senior Indebtedness. All provisions of this Article XII shall be subject to
Section 12.12.

SECTION 12.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or
distribution of the assets of the Company to creditors upon a total or partial
liquidation or a total or partial dissolution of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property:

          (1) holders of Senior Indebtedness shall be entitled to receive
          payment in full in cash of the Senior Indebtedness (including interest
          (if any), accruing on or after the commencement of a proceeding in
          bankruptcy, whether or not allowed as a claim against the Company in
          such bankruptcy proceeding) before Holders of Subordinated Debt
          Securities shall be entitled to receive any payment of principal of,
          or premium, if any, or interest on, the Subordinated Debt Securities;
          and

          (2) until the Senior Indebtedness is paid in full, any distribution to
          which Holders of Subordinated Debt Securities would be entitled but
          for this Article XII shall be made to holders of Senior Indebtedness
          as their interests may appear, except that such Holders may receive
          shares of stock and any debt securities that are subordinated to
          Senior Indebtedness to at least the same extent as the Subordinated
          Debt Securities.

SECTION 12.03. Default on Senior Indebtedness. The Company may not pay the
principal of, or premium, if any, or interest on, the Subordinated Debt
Securities or make any deposit pursuant to Article XI and may not repurchase,
redeem or otherwise retire (except, in the case of Subordinated Debt Securities
that provide for a mandatory sinking

                                       41


fund pursuant to Section 3.04, by the delivery of Subordinated Debt Securities
by the Company to the Trustee pursuant to the first paragraph of Section 3.05)
any Debt Securities (collectively, "pay the Subordinated Debt Securities") if
(i) any principal, premium or interest in respect of Senior Indebtedness is not
paid within any applicable grace period (including at maturity) or (ii) any
other default on Senior Indebtedness occurs and the maturity of such Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
(x) the default has been cured or waived and any such acceleration has been
rescinded or (y) such Senior Indebtedness has been paid in full in cash;
provided, however, that the Company may pay the Subordinated Debt Securities
without regard to the foregoing if the Company and the Trustee receive written
notice approving such payment from the Representative of each issue of
Designated Senior Indebtedness. During the continuance of any default (other
than a default described in clause (i) or (ii) of the preceding sentence) with
respect to any Senior Indebtedness pursuant to which the maturity thereof may be
accelerated immediately without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, the Company may not pay the Subordinated Debt Securities for a period
(a "Payment Blockage Period") commencing upon the receipt by the Company and the
Trustee of written notice of such default from the Representative of any
Designated Senior Indebtedness specifying an election to effect a Payment
Blockage Period (a "Blockage Notice") and ending 179 days thereafter (or earlier
if such Payment Blockage Period is terminated (i) by written notice to the
Trustee and the Company from the Person or Persons who gave such Blockage
Notice, (ii) by repayment in full in cash of such Designated Senior Indebtedness
or (iii) because the default giving rise to such Blockage Notice is no longer
continuing). Notwithstanding the provisions described in the immediately
preceding sentence (but subject to the provisions contained in the first
sentence of this Section 12.03), unless the holders of such Designated Senior
Indebtedness or the Representative of such holders shall have accelerated the
maturity of such Designated Senior Indebtedness, the Company may resume payments
on the Subordinated Debt Securities after such Payment Blockage Period. Not more
than one Blockage Notice may be given in any consecutive 360-day period,
irrespective of the number of defaults with respect to any number of issues of
Senior Indebtedness during such period; provided, however, that if any Blockage
Notice within such 360-day period is given by or on behalf of any holders of
Designated Senior Indebtedness (other than the Bank Indebtedness), the
Representative of the Bank Indebtedness may give another Blockage Notice within
such period; provided further, however, that in no event may the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period. For purposes of
this Section 12.03, no default or event of default which existed or was
continuing on the date of the commencement of any Payment Blockage Period with
respect to the Senior Indebtedness initiating such Payment Blockage Period shall
be, or be made, the basis of the commencement of a subsequent Payment Blockage
Period by the Representative of such Senior Indebtedness, whether or not within
a period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

SECTION 12.04. Acceleration of Payment of Debt Securities. If payment of the
Subordinated Debt Securities is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness (or their Representatives) of the acceleration.

SECTION 12.05. When Distribution Must Be Paid Over. If a distribution is made to
Holders of Subordinated Debt Securities that because of this Article XII should
not have been made to them, the Holders who receive such distribution shall hold
it in trust for holders of Senior Indebtedness and pay it over to them as their
interests may appear.

SECTION 12.06. Subrogation. After all the Senior Indebtedness is paid in full,
Holders of Subordinated Debt Securities shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article XII (equally and ratably with the
holders of all indebtedness of the Company which by its express terms is
subordinated to other indebtedness of the Company to substantially the same
extent as the Subordinated Debt Securities are subordinated and is entitled to
like rights of subrogation) to the rights of the holders of Senior Indebtedness
to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Indebtedness until the principal of and any
premium and interest on the Subordinated Debt Securities shall be paid in full;
and, for the purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which
the Holders of the Subordinated Debt Securities or the Trustee would be entitled
except for the provisions of this Article XII, and no payment over pursuant to
the provisions of this Article XII, to or for the benefit of the holders of
Senior Indebtedness by Holders of the Subordinated Debt Securities or the
Trustee, shall, as between the Company, its

                                       42


creditors other than holders of Senior Indebtedness, and the Holders of the
Subordinated Debt Securities, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness.

SECTION 12.07. Relative Rights. This Article XII defines the relative rights of
Holders of Subordinated Debt Securities and holders of Senior Indebtedness.
Nothing in this Indenture shall:

          (1) impair, as between the Company, its creditors (other than the
          holders of Senior Indebtedness), and Holders of either Subordinated
          Debt Securities or Debt Securities, the obligation of the Company,
          which is absolute and unconditional, to pay principal of, and premium,
          if any, and interest on, the Subordinated Debt Securities and the Debt
          Securities in accordance with their terms; or

          (2) prevent the Trustee or any Holder of either Subordinated Debt
          Securities or Debt Securities from exercising its available remedies
          upon a Default, subject to the rights of holders of Senior
          Indebtedness to receive distributions otherwise payable to Holders of
          Subordinated Debt Securities.

SECTION 12.08. Subordination May Not Be Impaired by Company. No right of any
holder of Senior Indebtedness to enforce the subordination of the Indebtedness
evidenced by the Subordinated Debt Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

SECTION 12.09. Rights of Trustee and Paying Agent. Notwithstanding Section
12.03, the Trustee or any paying agent may continue to make payments on
Subordinated Debt Securities and shall not be charged with knowledge of the
existence of facts that would prohibit the making of any such payments unless,
not less than two business days prior to the date of such payment, a responsible
officer of the Trustee receives notice satisfactory to it that payments may not
be made under this Article XII. The Company, the Registrar, any paying agent, a
Representative or a holder of Senior Indebtedness may give the notice; provided,
however, that, if an issue of Senior Indebtedness has a Representative, only the
Representative may give the notice.

The Trustee in its individual or any other capacity may hold Senior Indebtedness
with the same rights it would have if it were not Trustee. The Registrar and any
paying agent may do the same with like rights. The Trustee shall be entitled to
all the rights set forth in this Article XII with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness; and nothing in Article VII shall deprive
the Trustee of any of its rights as such holder. Nothing in this Article XII
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.06.

SECTION 12.10. Distribution or Notice to Representative. Whenever a distribution
is to be made or a notice given to holders of Senior Indebtedness, the
distribution may be made and the notice given to their Representative (if any).

SECTION 12.11. Article XII Not to Prevent Defaults or Limit Right to Accelerate.
The failure to make a payment pursuant to the Debt Securities by reason of any
provision in this Article XII shall not be construed as preventing the
occurrence of a Default. Nothing in this Article XII shall have any effect on
the right of the Holders or the Trustee to accelerate the maturity of either the
Subordinated Debt Securities or the Debt Securities, as the case may be.

SECTION 12.12. Trust Moneys Not Subordinated. Notwithstanding anything contained
herein to the contrary, payments from money or the proceeds of U.S. Government
Obligations held in trust under Article XI by the Trustee for the payment of
principal of, and premium, if any, and interest on, the Subordinated Debt
Securities or the Debt Securities shall not be subordinated to the prior payment
of any Senior Indebtedness or subject to the restrictions set forth in this
Article XII, and none of the Holders thereof shall be obligated to pay over any
such amount to the Company or any holder of Senior Indebtedness of the Company
or any other creditor of the Company.

SECTION 12.13. Trustee Entitled to Rely. Upon any payment or distribution
pursuant to this Article XII, the Trustee and the Holders shall be entitled to
rely (i) upon any order or decree of a court of competent jurisdiction in which
any proceedings of the nature referred to in Section 12.02 are pending, (ii)
upon a certificate of the liquidating trustee or agent or other Person making
such payment or distribution to the Trustee or to such Holders or (iii) upon the
Representatives for the holders of Senior Indebtedness for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other Indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other

                                       43


facts pertinent thereto or to this Article XII. The Trustee shall be entitled to
conclusively rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a Representative
on behalf of such holder), to establish that such notice has been given by a
holder of such Senior Indebtedness or Representative on behalf of any such
holder or holders. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article XII, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and other facts pertinent to the rights 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. The provisions of Sections
7.01 and 7.02 shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article XII.

SECTION 12.14. Trustee to Effectuate Subordination. Each Holder by accepting a
Subordinated Debt Security authorizes and directs the Trustee on his behalf to
take such action as may be necessary or appropriate to acknowledge or effectuate
the subordination between the Holders of Subordinated Debt Securities and the
holders of Senior Indebtedness as provided in this Article XII and appoints the
Trustee as attorney-in-fact for any and all such purposes.

SECTION 12.15. Trustee Not Fiduciary for Holders of Senior Indebtedness. With
respect to the holders of Senior Indebtedness, the Trustee undertakes to perform
or observe only such of its covenants and obligations as are specifically set
forth in this Article XII, and no implied covenants or obligations with respect
to the holders of Senior Indebtedness shall be read into this Indenture against
the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Holders of Subordinated Debt
Securities or the Company or any other Person, money or assets to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article XII
or otherwise.

SECTION 12.16. Reliance by Holders of Senior Indebtedness on Subordination
Provisions. Each Holder by accepting a Subordinated Debt Security acknowledges
and agrees that the foregoing subordination provisions are, and are intended to
be, an inducement and a consideration to each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Subordinated Debt Securities, to acquire and continue to hold,
or to continue to hold, such Senior Indebtedness and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness.

                                  ARTICLE XIII
                            Miscellaneous Provisions

SECTION 13.01. Successors and Assigns of Company Bound by Indenture. All the
covenant's stipulations, promises and agreements in this Indenture contained by
or in behalf of the Company or the Trustee shall bind its successors and
assigns, whether so expressed or not.

SECTION 13.02. Acts of Board, Committee or Officer of Successor Company Valid.
Any act or proceeding by any provision of this Indenture authorized or required
to be done or performed by any board, committee or officer of the Company shall
and may be done and performed with like force and effect by the like board,
committee or officer of any Successor Company.

SECTION 13.03. Required Notices or Demands. Except as otherwise expressly
provided in this Indenture, any notice or demand which by any provision of this
Indenture is required or permitted to be given or served by the Trustee or by
the Holders to or on the Company may be given or served by being deposited first
class mail, postage prepaid, in a post office letter box in the United States
addressed (until another address is filed by the Company with the Trustee) as
follows: Unit Corporation, 7130 South Lewis, Tulsa, Oklahoma 74136, Attention:
Chief Financial Officer.

                                       44


Except as otherwise expressly provided in this Indenture, any notice, direction,

prepaid, in a post office letter box in the United States addressed to the
corporate trust office of the Trustee initially at
[------------------------------------------].

The Company or the Trustee by notice to the other may designate additional or
different addresses for subsequent notices or communications.

Any notice required or permitted to a Registered Holder by the Company or the
Trustee pursuant to the provisions of this Indenture shall be deemed to be
properly mailed by being deposited first class mail, postage prepaid, in a post
office letter box in the United States addressed to such Holder at the address
of such Holder as shown on the Debt Security Register. Any report pursuant to
Section 313 of the Trust Indenture Act shall be transmitted in compliance with
subsection (c) therein.

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

Failure to mail a notice or communication to a Holder or any defect in it or any
defect in any notice by publication as to a Holder shall not affect the
sufficiency of such notice with respect to other Holders. If a notice or
communication is mailed or published in the manner provided above, it is
conclusively presumed duly given.

SECTION 13.04. Indenture and Debt Securities to Be Construed in Accordance with
the Laws of the State of New York. This Indenture and each Debt Security shall
be deemed to be New York contracts, and for all purposes shall be construed in
accordance with the laws of said State (without reference to principles of
conflicts of law).

SECTION 13.05. Officers' Certificate and Opinion of Counsel to Be Furnished upon
Application or Demand by the Company. Upon any application or demand by the
Company to the Trustee to take any action under any of the provisions of this
Indenture, the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent provided for in this Indenture relating to
the proposed action have been complied with and an Opinion of Counsel stating
that, in the opinion of such counsel, all such conditions precedent have been
complied with, except that in the case of any such application or demand as to

of this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

Each certificate (other than an Officers' Certificate provided pursuant to
Section 4.05) or opinion provided for in this Indenture and delivered to the
Trustee with respect to compliance with a condition or covenant provided for in
this Indenture shall include (1) a statement that the Person making such
certificate or opinion has read such covenant or condition, (2) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (3) a statement that, in the opinion of such Person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (4) a statement as to whether or not, in the opinion of such
Person, such condition or covenant has been complied with.

SECTION 13.06. Payments Due on Legal Holidays. In any case where the date of
maturity of interest on or principal of and premium, if any, on the Debt
Securities of a series or the date fixed for redemption or repayment of any Debt
Security or the making of any sinking fund payment shall not be a business day
at any Place of Payment for the Debt Securities of such series, then payment of
interest or principal and premium, if any, or the making of such sinking fund
payment need not be made on such date at such Place of Payment, but may be made
on the next succeeding business day at such Place of Payment with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date. If a record date is
not a business day, the record date shall not be affected.

SECTION 13.07. Provisions Required by Trust Indenture Act to Control. If and to
the extent that any provision of this Indenture limits, qualifies or conflicts
with another provision included in this Indenture which is required or deemed to
be included herein by operation of the Trust Indenture Act, such required or
deemed provision shall

                                       45

control. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act which may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or excluded,
as the case may be.

SECTION 13.08. Computation of Interest on Debt Securities. Interest, if any, on

Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Debt Security, each
Holder shall waive and release all such liability. The waiver and release shall
be part of the consideration for the issue of the Debt Securities.

SECTION 13.11. Severability. In case any provision in this Indenture or the Debt
Securities shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected

Unit Corporation
1000 Kensington Tower I
7130 South Lewis
Tulsa, Oklahoma 74136

     Re: Unit Corporation
         Registration Statement on Form S-3

Gentlemen:

     We have acted as counsel for Unit Corporation, a Delaware corporation (the
"Company"), in connection with the filing of a registration statement on Form
S-3 (the "Registration Statement") with the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended (the "Securities Act"), for
the registration from time to time of up to $250,000,000 aggregate amount of (i)
debt securities of the Company, which may be either senior or subordinated
(collectively, the "Debt Securities"), (ii) shares of the Company's preferred
stock, par value $1.00 per share (the "Preferred Stock"), (iii) shares of the
Company's common stock, par value $0.20 per share (the "Common Stock"), (iv)
Warrants representing rights to purchase Debt Securities, Preferred Stock or
Common Stock of the Company ("Warrants"), (v) purchase contracts for the
purchase or sale of debt or equity securities of the Company or any combination
thereof, ("Purchase Contracts"), and (vi) units consisting of one or more
Purchase Contracts, Warrants, Debt Securities, shares of Common Stock, shares of
Preferred Stock or any combination of such securities ("Units") and together
with the Debt Securities, Preferred Stock, Common Stock, Warrants and Purchase
Contracts (the "Securities"). The Securities will be sold or delivered from time
to time as set forth in the Registration Statement, any amendment thereto, the
prospectus contained therein (the "Prospectus") and supplements to the
Prospectus (the "Prospectus Supplements").

     We have examined (i) the Registration Statement, and (ii) the form of
Indenture relating to the Debt Securities (the "Indenture") to be executed by
the Company and an indenture trustee to be selected by the Company (the
"Trustee") filed as an exhibit to the Registration Statement. In addition, we
have (a) examined such certificates of public officials and of corporate
officers and directors and such other documents and matters as we have deemed
necessary or appropriate, (b) relied upon the accuracy of facts and information
set forth in all such documents, and (c) assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as copies, and
the authenticity of the originals from which all such copies were made.

     We have also assumed that (i) prior to the issuance of any Securities, (a)
the Registration Statement, as finally amended (including any necessary
post-effective amendments), and any additional registration statement filed
under Rule 462 under the Securities Act shall have been declared effective under
the Securities Act and such effectiveness shall not have been terminated or
rescinded, (b) an appropriate Prospectus Supplement describing the Securities
shall have been prepared, delivered and filed in compliance with the Securities
Act and the applicable rules and regulations thereunder, (c) the Securities
shall have been duly authorized by appropriate corporate action so as not to
violate any applicable law or result in a default under or breach of any
agreement or instrument binding upon the Company and so as to comply with any
requirement or restriction imposed by any court or government body having
jurisdiction over the Company and (d) there will exist under the Restated
Certificate of Incorporation of the Company (the "Certificate of Incorporation")
the requisite number of authorized but unissued shares of Common Stock and/or
Preferred Stock, as the case may be, and (ii) with respect to the issuance of
shares of each series of Preferred Stock offered from time to time under the
Registration Statement, the Board of Directors of the Company shall have
approved and adopted and filed with the Delaware Secretary of State a
Certificate of Designation of Preferences, Rights, Privileges and Restrictions
of Preferred Stock with respect to such series.

     Further, with respect to Warrants issued from time to time pursuant to any
warrant agreement(s) as shall be entered into by the Company (individually, a
"Warrant Agreement" and, collectively, the "Warrant Agreements"), to the extent
that the obligation of the Company under any such Warrant Agreement may be
dependent upon such matters, we assume for purposes of this opinion that (a) any
warrant agent named therein ("Warrant Agent") is duly qualified to engage in the
activities contemplated by the Warrant Agreement, (b) the Warrant Agreement has
been duly authorized, executed and delivered by the Warrant Agent and
constitutes the legally valid and binding obligation of the Warrant Agent
enforceable against the Warrant Agent in accordance with its terms, (c) the
Warrant Agent is in compliance, generally, with respect to acting as Warrant
Agent under the Warrant Agreement with all applicable laws and regulations, and
(d) the Warrant Agent has the requisite organizational and legal power and
authority to perform its obligations under the Warrant Agreement.

     We have further assumed that the Securities will be offered and sold
pursuant to and in accordance with the terms and conditions set forth in one or
more underwriting agreements (collectively, the "Underwriting Agreement")
between the Company and an investment banking firm or firms to be selected by
the Company as the Representative of the Underwriters for the Offering (the
"Underwriters"), covering the sale by the Company and the purchase by the
Underwriters of up to such number of Securities as shall have been authorized by
the Board of Directors of the Company, and providing, among other things, for
payment to the Company of such consideration for such purchase and sale as shall
constitute sufficient and valid consideration pursuant to the Certificate of
Incorporation, and the by-laws of the Company, as amended, and the laws of the
State of Delaware. We have also assumed that the choice of New York law to
govern the Indenture is a valid and legal provision.


     Based on the foregoing and subject to the qualifications and limitations
stated herein, we are of the opinion that:

     1. The Debt Securities proposed to be sold by the Company, when (i) all
necessary corporate action on the part of the Company has been taken to
authorize the issuance and sale of such Debt Securities; (ii) the Trustee has
been selected and qualified pursuant to the Trust Indenture Act of 1939, as
amended; (iii) the Indenture and any supplemental indenture in respect of the
Debt Securities have been duly executed and delivered; (iv) the terms of the
Debt Securities have been duly established in accordance with the Indenture and
any applicable supplemental indenture relating to the Debt Securities; and (v)
the Debt Securities have been duly executed and authenticated in accordance with
the Indenture and any related supplemental indenture in respect of the Debt
Securities and duly issued and delivered by the Company upon payment of the
consideration therefor in the manner contemplated in the Registration Statement
and any Prospectus Supplement relating thereto, will be validly issued and
constitute valid and binding obligations of the Company.

     2. The shares of Preferred Stock proposed to be sold by the Company, when
(i) all necessary corporate action on the part of the Company has been taken to
authorize the issuance and sale of such series of Preferred Stock and (ii) such
shares of Preferred Stock are issued and delivered upon payment of the
consideration therefor in the manner contemplated in the Registration Statement
and any Prospectus Supplement relating thereto, will be validly issued, fully
paid and non-assessable.

     3. The shares of Common Stock proposed to be sold by the Company, when (i)
all necessary corporate action on the part of the Company has been taken to
authorize the issuance and sale of such shares of Common Stock and (ii) such
shares of Common Stock are issued and delivered upon payment of the
consideration therefor in the manner contemplated in the Registration Statement
and any Prospectus Supplement relating thereto, will be validly issued, fully
paid and non-assessable.

     4. The Warrants proposed to be sold by the Company, when (i) all necessary
corporate action on the part of the Company has been taken to authorize the
issuance and sale of the Warrants and the issuance and sale of the Securities
issuable upon the exercise thereof; (ii) a Warrant Agreement relating to the
Warrants has been duly authorized and validly executed and delivered; (iii) the
Warrants have been duly authenticated by the Warrant Agent; and (iv) the
Warrants are issued and delivered upon payment of the consideration therefor in
the manner contemplated in the Registration Statement and any Prospectus
Supplement relating thereto, will be validly issued, fully paid and
non-assessable, and will constitute valid and binding obligations of the
Company.

     5. The Purchase Contracts proposed to be sold by the Company, when (i) all
necessary corporate action on the part of the Company has been taken to
authorize the issuance and sale of the Purchase Contracts; (ii) a purchase
contract agreement relating to the Purchase Contracts (the "Purchase Contract
Agreement") has been duly authorized and validly executed and delivered; and
(iii) the Purchase Contracts are issued and delivered by the Company upon
payment of the consideration therefor in the manner contemplated in the
Registration Statement and any Prospectus Supplement relating thereto, will be
validly issued and constitute valid and binding obligations of the Company.

     6. The Units, when (i) all necessary corporate action on the part of the
Company has been taken to authorize the issuance and sale of the Units; (ii) the
terms of the collateral arrangements, if any, relating to the Units have been
duly established and the agreement(s) relating thereto have been duly executed
and delivered and the collateral has been deposited with the collateral agent in
accordance with such arrangements; and (iii) the Units are issued and delivered
by the Company upon payment of the consideration therefor in the manner
contemplated by the Registration Statement and any Prospectus Supplement
relating thereto, will be validly issued and constitute valid and binding
obligations of the Company.

     We note that, as of the date of this opinion, a judgment for money in an
action based on a Security denominated in a foreign currency or currency unit in
a Federal or state court in the United States ordinarily would be enforced in
the United States only in United States dollars. The date used to determine the
rate of conversion of the foreign currency or currency unit in which a
particular Security is denominated into United States dollars will depend upon
various factors, including which court renders judgment. In the case of a
security denominated in a foreign currency, a state court in the State of New
York rendering a judgment on such Security would be required under Section 27 of
the New York Judiciary Law to render such judgment in the foreign currency in
which the security is denominated, and such judgment would be converted into
United States dollars at the exchange rate prevailing on the date of entry of
the judgment.

     Our opinions set forth in paragraphs 1, 4, 5 and 6 above are subject to the
effects of bankruptcy, insolvency, reorganization, fraudulent transfer or
conveyance, moratorium or other similar laws now or hereinafter in effect
relating to or affecting the enforcement of creditors' rights generally and by
general principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law).

     Our opinion expressed above is limited to the laws of the State of New
York, the corporate laws of the State of Delaware, and the federal laws of the
United States of America, and we do not express any opinion herein concerning
the laws of any other jurisdiction.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to our firm in the Prospectus constituting a part
of the Registration Statement under the caption "Legal Matters." In giving this
consent, we do not thereby admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act.



                                     Yours very truly,
                                     CONNER & WINTERS,
                                     P.C.

Ratio of Earning to Fixed Charges

The tables below set forth the ratios of earnings to fixed charges of the
Company and its consolidated subsidiaries for the periods indicated. The ratios
have been computed using the amounts for the Company and, its consolidated
subsidiaries. Earnings available for fixed charges represent earnings from
continuing operations before income taxes and fixed charges less income from
investments accounted for by the equity method. Fixed charges represent
interest incurred and guaranteed plus that portion of rental expense
deemed to be the equivalent of interest.
