<PAGE>
 
                                 RISK FACTORS
   
  Prospective purchasers of the Securities should carefully review the
information contained elsewhere in this Prospectus and any accompanying
Prospectus Supplement and should particularly consider the following matters:
    
REPLACEMENT OF RESERVES
 
  The Company's future success depends upon its ability to find, develop or
acquire additional oil and gas reserves that are economically recoverable. The
proved reserves of the Company will generally decline as reserves are
depleted, except to the extent that the Company conducts successful
exploration or development activities or acquires properties containing proved
reserves, or both. In order to increase reserves and production, the Company
must continue its development drilling and recompletion programs, pursue its
exploration drilling program or undertake other replacement activities. The
Company's current strategy includes increasing its reserve base through
acquisitions of producing properties, by continuing to exploit its existing
properties and, to a lesser extent, by pursuing exploration opportunities.
There can be no assurance, however, that the Company's planned development and
exploration projects and acquisition activities will result in significant
additional reserves or that the Company will have continuing success drilling
productive wells at low finding costs.
 
PRICE FLUCTUATIONS AND MARKETS
   
  The Company's results of operations are highly dependent upon the prices
received for the Company's oil and natural gas. Substantially all of the
Company's sales of oil and natural gas are made in the spot market, or
pursuant to contracts based on spot market prices, and not pursuant to long-
term, fixed-price contracts. Accordingly, the prices received by the Company
for its oil and natural gas production are dependent upon numerous factors
beyond the control of the Company. These factors include, but are not limited
to, the level of consumer product demand, weather conditions, governmental
regulations and taxes, the price and availability of alternative fuels, the
level of foreign imports of oil and natural gas, and the overall economic
environment. Any significant decline in prices for oil and natural gas could
have a material adverse effect on the Company's financial condition, results
of operations and quantities of reserves recoverable on an economic basis.
Should the industry experience significant price declines from current levels
or other adverse market conditions, the Company may not be able to generate
sufficient cash flow from operations to meet its obligations and make planned
capital expenditures. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources,"
"Business and Properties--Competition and Markets" and "--Federal and State
Regulations," incorporated herein by reference from the Company's Annual
Report on Form 10-K for the year ended December 31, 1997 (the "Annual Report
on Form 10-K").     
 
  The availability of a ready market for the Company's oil and natural gas
production also depends on a number of factors, including the demand for and
supply of oil and natural gas and the proximity of reserves to, and the
capacity of, oil and gas gathering systems, pipelines or trucking and terminal
facilities. Wells may be shut-in for lack of a market or due to inadequacy or
unavailability of pipeline or gathering system capacity.
 
SUBSTANTIAL INDEBTEDNESS
 
  The Company has incurred a substantial amount of indebtedness and may incur
additional indebtedness under existing and future credit agreements or
pursuant to public or private offerings of debt securities. This level of
indebtedness may pose substantial risks to holders of Securities offered
pursuant to this Prospectus, including the possibility that the Company might
not generate sufficient cash flow to pay the principal of and interest on Debt
Securities offered hereby. If the Company is unsuccessful in increasing its
proved reserves or realizing production from its proved undeveloped reserves,
the future net revenue from existing proved reserves may not be sufficient to
pay the principal of and interest on debt securities issued by the Company and
would adversely affect the value of any preferred stock or common stock
outstanding. Such indebtedness may also adversely affect the Company's ability
to finance its future operations and capital needs, and may limit its ability
to pursue other business opportunities.
 
                                       3
<PAGE>
 
SUBSTANTIAL CAPITAL REQUIREMENTS
 
  The Company makes, and will continue to make, substantial capital
expenditures for the acquisition, development, production, exploration and
abandonment of its oil and natural gas reserves. The Company intends to
finance such capital expenditures primarily with funds provided by operations
and borrowings under its bank credit agreement.
   
  If revenues decrease as a result of lower oil or gas prices or otherwise,
the Company may have limited ability to expend the capital necessary to
replace its reserves or to maintain production at current levels, resulting in
a decrease in production over time. If the Company's cash flow from operations
is not sufficient to satisfy its capital expenditure requirements, there can
be no assurance that additional debt or equity financing will be available to
meet these requirements. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources," incorporated herein by reference from the Company's Annual Report
on Form 10-K.     
 
COMPETITION
 
  The oil and natural gas industry is highly competitive. The Company will
compete in the acquisition, development, production and marketing of oil and
natural gas with major oil companies, other independent oil and natural gas
concerns and individual producers and operators. Many of these competitors
have substantially greater financial and other resources than the Company.
Furthermore, the oil and natural gas industry competes with other industries
in supplying the energy and fuel needs of industrial, commercial and other
consumers. See "Business and Properties--Competition and Markets,"
incorporated herein by reference from the Company's Annual Report on Form 10-
K.
 
ACQUISITION RISKS
   
  The Company constantly evaluates acquisition opportunities and frequently
engages in bidding and negotiation for acquisitions, many of which are
substantial. If successful in this process, the Company may be required to
alter or increase its capitalization substantially to finance these
acquisitions through the issuance of additional debt or equity securities, the
sale of production payments or otherwise; however, the Company's current bank
revolving credit agreement and the indentures governing outstanding
indebtedness contain covenants that limit the Company's ability to incur
additional indebtedness. See "--Substantial Indebtedness." These changes in
capitalization may significantly affect the risk profile of the Company.
Additionally, significant acquisitions can change the nature of the operations
and business of the Company depending upon the character of the acquired
properties, which may be substantially different in operating or geologic
characteristics or geographic location than existing properties. Moreover,
there can be no assurance that the Company will be successful in the
acquisition of any material property interests. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources," incorporated herein by reference from the Company's Annual
Report on Form 10-K.     
 
DRILLING RISKS
 
  Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that new wells drilled by the Company will be productive or that the
Company will recover all or any portion of its investment. Drilling for oil
and natural gas may involve unprofitable efforts, not only from dry wells, but
from wells that are productive but do not produce sufficient net revenues to
return a profit after drilling, operating and other costs. The cost of
drilling, completing and operating wells is often uncertain. The Company's
drilling operations may be curtailed, delayed or canceled as a result of
numerous factors, many of which are beyond the Company's control, including
title problems, weather
 
                                       4
<PAGE>
 
conditions, compliance with governmental requirements and shortages or delays
in the delivery of equipment and services.
 
OPERATING HAZARDS AND UNINSURED RISKS
   
  The Company's operations are subject to hazards and risks inherent in
drilling for, producing and transporting oil and natural gas, such as fires,
natural disasters, explosions, encountering formations with abnormal
pressures, blowouts, collapse of wellbore, casing or other tubulars, pipeline
ruptures and spills, any of which can result in loss of hydrocarbons,
environmental pollution, personal injury claims and damage to properties of
the Company and others. As protection against operating hazards, the Company
maintains insurance coverage against some, but not all, potential losses. The
Company's coverages include, but are not limited to, operator's extra expense,
physical damage on certain assets, employer's liability, comprehensive general
liability, automobile and workers' compensation insurance. The Company
believes that its insurance is adequate and customary for companies of a
similar size engaged in operations similar to those of the Company, but losses
could occur for uninsurable or uninsured risks or in amounts in excess of
existing insurance coverage. The occurrence of an event that is not fully
covered by insurance could have an adverse impact on the Company's financial
condition and results of operations.     
 
UNCERTAINTY OF ESTIMATES OF RESERVES AND FUTURE NET REVENUES
 
  There are numerous uncertainties inherent in estimating quantities of proved
reserves, including many factors beyond the control of the Company. The
information relating to Company oil and natural gas reserves incorporated
herein by reference represents estimates based on reports prepared by the
Company's independent petroleum engineers, as well as internally generated
reports. Petroleum engineering is not an exact science. Information relating
to the Company's proved oil and natural gas reserves is based upon engineering
estimates. Estimates of economically recoverable oil and natural gas reserves
and of future net cash flows necessarily depend upon a number of variable
factors and assumptions, such as historical production from the area compared
with production from other producing areas, the assumed effects of regulation
by governmental agencies and assumptions concerning future oil and natural gas
prices, future operating costs, severance and excise taxes, capital
expenditures and workover and remedial costs, all of which may in fact vary
considerably from actual results. For these reasons, estimates of
classifications of such reserves based on risk of recovery and estimates of
expected future cash flows prepared by different engineers or by the same
engineers at different times may vary substantially. Actual production,
revenues and expenditures with respect to the Company's reserves will likely
vary from estimates, and such variances may be material.
 
DEPENDENCE UPON KEY PERSONNEL
 
  The success of the Company has been and will continue to be highly dependent
on the Company's Chairman of the Board of Directors and Chief Executive
Officer, Bob R. Simpson, its Vice Chairman of the Board and President, Steffen
E. Palko, and a limited number of other senior management personnel. Loss of
the services of Mr. Simpson or Mr. Palko or any of those other individuals
could have a material adverse impact on the Company's operations. The Company
can make no assurance regarding the future affiliation of any of such persons
with the Company.
 
GOVERNMENTAL REGULATION
 
  The Company's operations are affected by extensive regulation pursuant to
various federal, state and local laws and regulations relating to the
exploration for, and the development, production, gathering and marketing of,
oil and natural gas and the release of material into the environment or
otherwise relating to protection of the environment. In particular, the
Company's oil and natural gas exploration, development and production, and its
activities in connection with the storage and transportation of liquid
hydrocarbons, are subject to stringent environmental regulations by
governmental authorities. Such regulations have increased the costs of
planning, designing, drilling, installing, operating and abandoning oil and
natural gas wells and other related facilities, and such regulations may
become more onerous in the future.
 
                                       5
<PAGE>
 
  The Company may be required to expend significant resources, both financial
and managerial, to comply with environmental regulations and permitting
requirements. Although the Company believes that its operations are in general
compliance with all such laws and regulations, including applicable
environmental laws and regulations, risks of substantial costs and liabilities
are inherent in oil and natural gas operations, and there can be no assurance
that significant costs and liabilities will not be incurred in the future.
Moreover, it is possible that other developments, such as increasingly strict
environmental laws, regulations and enforcement policies thereunder, and
claims for damages to property, employees, other persons and the environment
resulting from the Company's operations, could result in substantial costs and
liabilities in the future.
 
  The Company expects to maintain customary insurance coverage for its
operations, including coverage for sudden environmental damages, but does not
believe that insurance coverage for environmental damages that occur over time
will be available at a reasonable cost. Moreover, the Company does not believe
that insurance coverage against the full potential liability that could be
caused by sudden environmental damages is available at a reasonable cost.
Accordingly, the Company might be subject to uninsured liability because of
the prohibitive premium costs of insuring against certain hazards. See
"Business and Properties--Federal and State Regulations" and "--Environmental
Regulations," incorporated herein by reference from the Company's Annual
Report on Form 10-K.
 
                          FORWARD-LOOKING STATEMENTS
   
  Certain statements incorporated by reference in this Prospectus from

uncertainties and other factors which could cause actual results to differ
materially from future results expressed or implied by such forward-looking
statements. The most significant of such risks, uncertainties and other
factors are discussed under "Risk Factors" in this Prospectus and any
accompanying Prospectus Supplement, and under "Management's Discussion and
Analysis of Financial Condition and Results of Operations," incorporated by
reference herein from the Company's Annual Report on Form 10-K, and
prospective investors are urged to carefully consider such factors.

Company's oil and gas reserves are principally located in relatively long-
lived fields with well-established production histories concentrated in
western Oklahoma, the Permian Basin of West Texas and New Mexico, the Hugoton
Field of Oklahoma and Kansas, the Green River Basin of Wyoming, and the San
Juan Basin of northwestern New Mexico.
 
  The Company is a Delaware corporation. Its principal executive offices are
located at 810 Houston Street, Suite 2000, Fort Worth, Texas 76102 and its
telephone number is (817) 870-2800.
 
                                USE OF PROCEEDS
 
  Except as otherwise described in the applicable Prospectus Supplement, the
net proceeds from the sale of Securities will be used for general corporate
purposes, which may include refinancings or repayments of indebtedness,
property acquisitions, capital expenditures, working capital, acquisitions and
repurchases and redemptions of securities.
 
                      RATIO OF EARNINGS TO FIXED CHARGES

(a) For purposes of calculating this ratio, earnings include income (loss)
    from continuing operations before income tax and fixed charges. Fixed
    charges include interest expense, preferred stock dividends and an imputed
    interest expense on operating lease rentals (assumed as one-third of
    rentals).
(b) Earnings were insufficient to cover fixed charges by $0.4 million due to
    the effect of a one-time, non-cash accounting charge of $4 million for net
    deferred income tax liabilities upon the merger of the Company with the
    predecessor partnership. Excluding the effect of this charge, the ratio of
    earnings to fixed charges would have been 1.6x.
(c) Earnings were insufficient to cover fixed charges by $16.4 million due to
    the effect of a $20.3 million pre-tax, non-cash impairment charge recorded
    upon adoption of Statement of Financial Accounting Standards No. 121,
    Accounting for the Impairment of Long-Lived Assets and for Long-Lived
    Assets to be Disposed of. Excluding the effect of this charge, the ratio
    of earnings to fixed charges would have been 1.3x.

                        DESCRIPTION OF DEBT SECURITIES
 
  The following is a description of certain general terms and provisions of
the Debt Securities. The particular terms of any series of Debt Securities
will be described in the applicable Prospectus Supplement. If so indicated in
a Prospectus Supplement, the terms of any such series may differ from the
terms set forth below.
 
  Debt Securities may be issued from time to time in one or more series by the
Company. The Debt Securities will constitute either indebtedness designated as
Senior Indebtedness ("Senior Securities"), indebtedness designated as Senior
Subordinated Indebtedness ("Senior Subordinated Securities") or indebtedness
designated as Subordinated Indebtedness ("Subordinated Securities"). The
Company may issue Debt Securities with different terms from those of Debt
Securities previously issued without the consent of holders of previously
issued series of Debt Securities. The particular terms of each series of
Securities offered by a particular Prospectus Supplement will be described
therein. Senior Securities, Senior Subordinated Securities and Subordinated
Securities will each be issued under a separate indenture (individually, an
"Indenture" and, collectively, the "Indentures") to be entered into prior to
the issuance of such Debt Securities. The Indentures will be substantially
identical, except for provisions relating to subordination. See "--
Subordination of Senior Subordinated Securities and Subordinated Securities."
A copy of the form of the Indenture is filed as an Exhibit to the Registration
Statement of which this Prospectus is a part. There will be a separate Trustee
(individually, a "Trustee" and, collectively, the "Trustees") under each
Indenture. Information regarding the Trustee under an Indenture will be
included in any Prospectus Supplement relating to the Debt Securities issued
thereunder.
 
  The following discussion includes a summary description of material terms of
the Indentures, other than terms that are specific to a particular series of
Debt Securities and that will be described in the Prospectus Supplement
relating to such series. The following summaries do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, all
of the provisions of the Indentures, including the definitions therein of
certain terms capitalized in this Prospectus. Wherever particular Sections or
Articles or defined terms of the Indentures are referred to herein or in a
Prospectus Supplement, such Sections or defined terms are incorporated herein
or therein by reference.
 
  To the extent applicable to the Debt Securities of a particular series, as
indicated in the applicable Prospectus Supplement, there are no provisions of
the Indentures that afford holders of the Debt Securities protection in the
event of a highly leveraged transaction involving the Company.
 
GENERAL
 
  Debt Securities will be general unsecured obligations of the Company. The
Indentures do not limit the aggregate amount of Debt Securities that may be
issued under each Indenture, and Debt Securities may be issued under the
Indentures from time to time in separate series up to the aggregate amount
authorized from time to time by the Company for each series. Debt Securities
of a series will be issuable only in registered form without coupons in
denominations of $1,000 and integral multiples thereof, or in the form of one
or more Global Securities in registered form (each a "Global Security"). The
Senior Securities will be unsecured and unsubordinated obligations of the
Company and will rank equally and ratably with other unsecured and
unsubordinated indebtedness of the Company. The Senior Subordinated Securities
and the Subordinated Securities will be subordinated in right of payment to
the prior payment in full of the Senior Indebtedness, including the Senior
Securities, of the Company, and the Subordinated Securities will be
subordinated in right of payment to the prior payment in full of the Senior
Subordinated Indebtedness, including the Senior Subordinated Securities, as
described below under "Subordination of Senior Subordinated Securities and
Subordinated Securities" and in a Prospectus Supplement applicable to an
offering of Senior Subordinated Securities or Subordinated Securities.
 
  The applicable Prospectus Supplement or Prospectus Supplements will describe
the following terms of the series of Debt Securities in respect of which this
Prospectus is being delivered: (1) the title of such Debt Securities; (2) any
limit on the aggregate principal amount of such Debt Securities; (3) whether
any of such Debt
 
                                       8
<PAGE>
 
   
Securities are to be issuable as a Global Security, whether such Global
Securities are to be issued in temporary global form or permanent global form,
and, if so, the terms and conditions, if any, upon which interests in such
Securities in global form may be exchanged, in whole or in part, for the
individual Debt Securities represented thereby; (4) the date or dates on which
such Debt Securities will mature; (5) the rate or rates of interest, if any,
or the method of calculation thereof, that such Debt Securities will bear; (6)
the date or dates from which any such interest will accrue, the interest
payment dates on which any such interest on such Debt Securities will be
payable and the record date for any interest payable on any interest payment
date; (7) the place or places where the principal of, premium (if any) and
interest on such Debt Securities will be payable; (8) the period or periods
within which, the events upon the occurrence of which, and the price or prices
at which, such Debt Securities may, pursuant to any optional or mandatory
provisions, be redeemed or purchased, in whole or in part, by the Company and
any terms and conditions relevant thereto; (9) the obligation of the Company,
if any, to redeem or repurchase such Debt Securities at the option of the
holders; (10) any index or formula used to determine the amount of payments of
principal of and any premium and interest on such Debt Securities; (11) if
other than the principal amount thereof, the portion of the principal amount
of such Debt Securities of the series that will be payable upon declaration of
the acceleration of the maturity thereof; (12) any additional covenants of the
Company; (13) the terms and conditions, if any, pursuant to which such Debt
Securities are convertible or exchangeable into Common Stock; and (14) any
other terms of such Debt Securities not inconsistent with the provisions of
the applicable Indentures.     
 
  Debt Securities may be issued at a discount from their principal amount.
United States federal income tax considerations and other special
considerations applicable to any such original issue discount securities will
be described in the applicable Prospectus Supplement.
 
  If the purchase price of any of the Debt Securities is denominated in a
foreign currency or currencies or a foreign currency unit or units or if the
principal of and any premium and interest on any series of Debt Securities is
payable in a foreign currency or currencies or a foreign currency unit or
units, the restrictions, elections, general tax considerations, specific terms
and other information with respect to such issue of Debt Securities and such
foreign currency or currencies or foreign currency unit or units will be set
forth in the applicable Prospectus Supplement.
 
SENIOR SECURITIES
 
  The Senior Securities will rank pari passu with all other unsecured and
unsubordinated debt of the Company, including Senior Indebtedness, and senior
to the Senior Subordinated Indebtedness and Subordinated Indebtedness.
 
SUBORDINATION OF SENIOR SUBORDINATED SECURITIES AND SUBORDINATED SECURITIES
 
  The payment of the principal of, premium, if any, and interest on the Senior
Subordinated Securities and the Subordinated Securities will, to the extent
set forth in the respective Indentures governing such Senior Subordinated
Securities and Subordinated Securities, be subordinated in right of payment to
the prior payment in full of all Senior Indebtedness (including the Senior
Securities), and payments in respect of the Subordinated Securities will be
subordinated to the prior payment in full of all Senior Subordinated
Indebtedness. Upon any payment or distribution of assets to creditors upon any
liquidation, dissolution, winding up, reorganization, assignment for the
benefit of creditors, marshaling of assets or any bankruptcy, insolvency or
similar proceedings of the Company, (1) the holders of all Senior Indebtedness
will be entitled to receive payment in full of all amounts due or to become
due thereon before the holders of the Senior Subordinated Securities or the
Subordinated Securities will be entitled to receive any payment of the
principal of, premium, if any, or interest on such Senior Subordinated
Securities or Subordinated Securities, as the case may be, and (2) the holders
of Senior Subordinated Securities will be entitled to receive payment in full
in respect thereof before holders of Subordinated Securities are entitled to
receive any payments in respect of such Subordinated Securities. In the event
of the acceleration of the maturity of any Senior Subordinated Securities or
Subordinated Securities, the holders of all Senior Indebtedness will be
entitled to receive payment in full of all amounts due or to become
 
                                       9
<PAGE>
 
due thereon before the holders of the Senior Subordinated Securities or
Subordinated Securities, as the case may be, will be entitled to receive any
payment upon the principal of, premium, if any, or interest on such Senior
Subordinated Securities or Subordinated Securities, as the case may be. Upon
acceleration of the maturity of any Subordinated Securities, the holders of
any Senior Subordinated Indebtedness will be entitled to receive payment in
full of the Senior Subordinated Indebtedness before the holders of
Subordinated Securities are entitled to receive any payments in respect
thereof.
 
  No payments of principal of, premium, if any, or interest on the Senior
Subordinated Securities or Subordinated Securities may be made if there shall
have occurred and be continuing a default in the payment of principal of,
premium, if any, or interest on any Senior Indebtedness (and, in the case of
the Subordinated Securities, on any Senior Subordinated Indebtedness) beyond
any applicable grace period. During the continuance of any default, other than
a default in the payment of principal of, premium, if any, or interest, on
Senior Indebtedness (and in the case of Subordinated Securities, on Senior
Subordinated Indebtedness) pursuant to which the maturity thereof may be
accelerated, upon receipt by the Trustee for Senior Subordinated Securities or
Subordinated Securities of notice from holders of Senior Indebtedness (and/or
Senior Subordinated Indebtedness) the Company will be restricted, as set forth
in the applicable Indenture from making any payments to holders of Senior
Subordinated Securities and/or Subordinated Securities.
 
  The failure of the Company to make any payment on the Senior Subordinated
Securities or the Subordinated Securities when due or within any applicable
grace period, including as a result of a nonpayment default on any Senior
Indebtedness (or in the case of Subordinated Securities, on any Senior
Subordinated Indebtedness), will constitute an Event of Default under the
applicable Indenture and will entitle holders of the Senior Subordinated
Securities and/or Subordinated Securities, as applicable, to accelerate the
maturity thereof.
 
  The Indenture pertaining to the Senior Subordinated Securities will provide
that the Company will not incur any Indebtedness which is expressly
subordinated in right of payment to Senior Indebtedness unless such
Indebtedness ranks pari passu with or subordinate to the Senior Subordinated
Securities.
 
  The Company conducts some of its operations through subsidiaries. The Debt
Securities are obligations only of the Company and not of the subsidiaries. As
an equity holder of its subsidiaries, the right of the Company to receive
assets from a subsidiary upon the bankruptcy, liquidation or reorganization of
such subsidiary (and therefore the right of the holders of Debt Securities to
realize value from such assets) will be effectively subordinated to the claims
of all creditors of that subsidiary, except to the extent that the Company is
recognized as a creditor of the subsidiary.
 
  By reason of such provisions, in the event of insolvency of the Company,
holders of Senior Subordinated Securities and Subordinated Securities may
recover less, ratably, than holders of Senior Indebtedness with respect
thereto, and holders of Subordinated Securities may recover less, ratably,
than holders of Senior Subordinated Securities with respect thereto.
 
  If this Prospectus is being delivered in connection with a series of Senior
Subordinated Securities or Subordinated Securities, the accompanying
Prospectus Supplement or the information incorporated herein by reference will
set forth the approximate amount of Senior Indebtedness outstanding as of the
end of the Company's most recently completed fiscal quarter.
 
CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Company will be obligated to
make an offer to purchase all of the then outstanding Debt Securities (a
"Change of Control Offer"), and purchase, on a business day (the "Change of
Control Purchase Date") not more than 70 nor fewer than 30 days following the
Change of Control, all of the then outstanding Debt Securities validly
tendered pursuant to such Change of Control Offer at a purchase price (the
"Change of Control Purchase Price") equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the Change of Control
Purchase Date. The Change of Control Offer is
 
                                      10
<PAGE>
 
required to remain open for at least 20 Business Days and until the close of
business on the fifth business day prior to the Change of Control Purchase
Date.
 
  In order to effect such Change of Control Offer, the Company, not later than
the 30th day after the Change of Control, will mail to each holder of Debt
Securities a notice of the Change of Control Offer, which notice will govern
the terms of the Change of Control Offer and state, among other things, the
procedures that holders of Debt Securities must follow to accept the Change of
Control Offer.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Debt Securities delivered by holders thereof
seeking to accept the Change of Control Offer. If on a Change of Control
Purchase Date the Company does not have available funds sufficient to pay the
Change of Control Purchase Price or is prohibited from purchasing the Debt
Securities, an Event of Default will occur under the applicable Indenture. The
definition of "Change of Control" includes an event by which the Company
sells, conveys, transfers or leases all or substantially all of its properties
to any Person; the phrase "all or substantially all" is subject to applicable
legal precedent and as a result in the future there may be uncertainty as to
whether a Change of Control has occurred.
 
  The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer at the
same purchase price, at the same times and otherwise in substantial compliance
with the requirements applicable to a Change of Control Offer made by the
Company and purchases all Debt Securities validly tendered and not withdrawn
under such Change of Control Offer.
 
  The Company intends to comply with Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder, if applicable, in the event
that a Change of Control occurs and the Company is required to purchase Debt
Securities as described above. The existence of a holder's right to require,
subject to certain conditions, the Company to repurchase its Debt Securities
upon a Change of Control may deter a third party from acquiring the Company in
a transaction that constitutes, or results in, a Change of Control.
 
REPORTS
 
  The Company will file on a timely basis with the Commission, to the extent
such filings are accepted by the Commission and whether or not the Company has
a class of securities registered under the Exchange Act, the annual reports,
quarterly reports and other documents that the Company would be required to
file if it were subject to Section 13 or 15(d) of the Exchange Act. The
Company will also be required to file copies of such reports and documents
with the Trustee under each Indenture with outstanding Debt Securities within
15 days after the date on which the Company files, or would be required to
file, such reports and documents with the Commission.
 
MERGER, CONSOLIDATION AND SALE OF ASSETS, ETC.
 
  The Company will not, in any single transaction or series of related
transactions, merge or consolidate with or into any other Person, or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially
all of its properties and assets to any Person or group of affiliated Persons,
and the Company will not permit any of its subsidiaries to enter into any such
transaction or series of transactions if such transaction or series of
transactions, in the aggregate, would result in a sale, assignment,
conveyance, transfer, lease or other disposition of all or substantially all
of the properties and assets of the Company and its subsidiaries on a
consolidated basis to any other Person or group of affiliated Persons, unless
at the time and after giving effect thereto (1) either (A) if the transaction
or transactions is a merger or consolidation, the Company will be the
surviving Person of such merger or consolidation, or (B) the Person (if other
than the Company) formed by such consolidation or into which the Company or
such subsidiary is merged or to which the properties and assets of the Company
or such subsidiary, as the case may be, are sold, assigned, conveyed,
transferred, leased or otherwise disposed of is a corporation organized and
existing under the laws of the United States of America, any state thereof or
the District of Columbia and, in either case, expressly assumes by a
supplemental indenture to the Indentures, all the obligations
 
                                      11
<PAGE>
 
of the Company under the Debt Securities and the Indentures, and, in each
case, the Indentures remain in full force and effect; (2) immediately before
and immediately after giving effect to such transaction or series of
transactions on a pro forma basis, no Event of Default shall have occurred and
be continuing; and (3) if any of the properties or assets of the Company or
any of its subsidiaries would upon such transaction or series of related
transactions become subject to any lien, the creation and imposition of such
lien will be in compliance with the terms of the Indentures.
 
EVENTS OF DEFAULT
 
  The following will constitute Events of Default under the Indentures with
respect to Debt Securities of any series: (1) failure to pay principal (or
premium, if any) on any Debt Security of that series when due (whether at
maturity, upon redemption, upon repurchase pursuant to a Change of Control
Offer, by acceleration or otherwise); (2) failure to pay any interest on any
Debt Security of that series when due, which failure continues for 30 days;
(3) default in the performance of the provisions contained in the "Merger,
Consolidation and Sale of Assets" section of the applicable Indenture; (4)
failure to perform any other covenant of the Company in the applicable
Indenture or any other covenant to which the Company may be subject with
respect to Debt Securities of that series (other than a covenant solely for
the benefit of a series of Debt Securities other than that series), which
failure continues for 30 days after written notice as provided in the
applicable Indenture; (5) certain events of bankruptcy, insolvency or
reorganization; and (6) such other events as are set forth in the applicable
Indenture supplement relating to such Debt Securities.
 
  If an Event of Default with respect to outstanding Debt Securities of any
series occurs and is continuing, either the Trustee or the holders of at least
25% in principal amount of the outstanding Debt Securities of that series, by
notice as provided in the applicable Indenture, may declare the principal
amount (or, if the Debt Securities of that series are original issue discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) of all Debt Securities of that series to be due and
payable immediately, except that upon the occurrence of an Event of Default
specified in (5) in the preceding paragraph, the principal amount (or in the
case of original issue discount Securities, such portion) of all Debt
Securities will be immediately due and payable without any action by the
Trustee or any holder. At any time after a declaration of acceleration with
respect to Debt Securities of any series has been made, but before judgment or
decree based on such acceleration has been obtained, the holders of a majority
in principal amount of the outstanding Debt Securities of that series may,
under certain circumstances, rescind and annul such acceleration. For
information as to waiver of defaults, see "Amendments and Waivers" below.
 
  Subject to the duty of the respective Trustees during an Event of Default to
act with the required standard of care, each such Trustee will be under no
obligation to exercise any of its rights or powers under the respective
Indentures at the request or direction of any of the holders, unless such
holders shall have offered to such Trustee reasonable security or indemnity.
Subject to certain provisions, including those requiring security or
indemnification of the applicable Trustee, the holders of a majority in
principal amount of the outstanding Debt Securities of any series will 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 such Trustee, with respect to the Debt Securities of that series.
 
  No holder of a Debt Security of any series will have any right to institute
any proceeding with respect to the applicable Indenture or for any remedy
thereunder, unless such holder shall have previously given to the applicable
Trustee written notice of a continuing Event of Default and unless the holders
of at least 25% in aggregate principal amount of the outstanding Debt
Securities of the same series shall have provided written requests, and
offered reasonable indemnity, to such Trustee to institute such a proceeding,
and the Trustee shall not have received from the holders of a majority in
aggregate principal amount of the outstanding Debt Securities of the same
series a direction inconsistent with such request and shall have failed to
institute such proceeding within 60 days. However, such limitations do not
apply to a suit instituted by a holder of a Debt Security for enforcement of
payment of the principal of and interest on such Debt Security on or after the
respective due dates expressed in such Debt Security.
 
                                      12

  The Company is required to furnish to the Trustees annually a statement as
to the performance by the Company of its obligations under the respective
Indentures and as to any default in such performance.
 
SATISFACTION AND DISCHARGE
 
  An Indenture will be discharged and will cease to be of further effect,
except as to surviving rights or registration of transfer or exchange of the
Debt Securities to which such Indenture pertains, as expressly provided for in
such Indenture, as to all such Debt Securities outstanding when (1) either (A)
all such outstanding Debt Securities have been delivered to the Trustee for
cancellation or (B) all such outstanding Debt Securities not theretofore
delivered to the Trustee for cancellation have become due and payable or will
become due and payable at their stated maturity within one year, or are to be
called for redemption within one year under arrangements satisfactory to the
Trustee for the serving of notice of redemption by the Trustee, and the
Company has irrevocably deposited or caused to be deposited with the Trustee
funds in an amount sufficient to pay and discharge the entire indebtedness on
such Debt Securities not theretofore delivered to the Trustee for
cancellation, for principal of, premium, if any, and interest on such Debt
Securities to the date of deposit or to the stated maturity or redemption
date, as the case may be, together with instructions from the Company
irrevocably directing the Trustee to apply such funds to the payment thereof
at maturity or redemption, as the case may be, (2) the Company has paid all
other sums payable under such Indenture by the Company; and (3) the Company
has delivered to the Trustee an officers' certificate and an opinion of
counsel satisfactory to the Trustee, which, taken together, state that all
conditions precedent under such Indenture relating to the satisfaction and
discharge thereof have been complied with.
 
AMENDMENTS AND WAIVERS
 
  From time to time, the Company and the Trustee may, without the consent of
the holders of Debt Securities, amend, waive or supplement the Indenture to
which such Debt Securities pertain or such Debt Securities for certain
specified purposes, including, among other things, curing ambiguities, defects
or inconsistencies, qualifying, or maintaining the qualification of, such
Indenture under the Trust Indenture Act of 1939, or making any change that
does not adversely affect the rights of any holder of such Debt Securities.
Other amendments and modifications of an Indenture or a series of Debt
Securities may be made by the Company and the Trustee with the consent of the
holders of not less than a majority of the aggregate principal amount of the
Debt Securities of such series then outstanding; provided, however, that no
such modification or amendment may, without the consent of the holder of each
outstanding Debt Security affected thereby, (1) change the stated maturity of
the principal of, or any installment of interest on, any Debt Security, (2)
reduce the principal amount of, premium, if any, or interest on any Debt
Security, (3) change the currency of payment of any Debt Security, (4) impair
the right to institute suit for the enforcement of any payment on any Debt
Security, (5) reduce the percentage of aggregate principal amount of
outstanding Debt Securities of a series necessary to amend the Indenture or to
waive compliance with certain provisions of the Indenture or to waive certain
defaults, or (6) modify the obligation of the Company to make and consummate a
Change of Control Offer in the event of a Change of Control.
 
  The holders of a majority in aggregate principal amount of the outstanding
Debt Securities of any series may waive compliance by the Company with certain
restrictive provisions of, and any past default under, the applicable
Indenture with respect to that series, except a default in the payment of
principal of, premium, if any, or interest on any Debt Security of that series
or a provision of an applicable Indenture which cannot be modified without the
consent of each holder of the Debt Security affected.
 
DEFEASANCE
 
  If so indicated in the applicable Prospectus Supplement with respect to the
Debt Securities of a series, the Company at its option (i) will be discharged
from any and all obligations in respect of the Debt Securities of such series
(except for certain obligations to register the transfer or exchange of Debt
Securities of such series, to replace destroyed, stolen, lost or mutilated
Debt Securities of such series, and to maintain an office or agency
 
                                      13
<PAGE>
 
in respect of the Debt Securities and hold moneys for payment in trust) or
(ii) will (A) be released from its obligations to comply with certain
covenants relating to the Debt Securities of such series and (B) no longer be
subject to certain Events of Default with respect to the Debt Securities of
such series, in each case, as specified in the applicable Prospectus
Supplement. The Company may elect such discharge or release only if the
Company irrevocably deposits with the applicable Trustee, in trust, money,
government obligations of the government issuing the currency in which the
Debt Securities of the relevant series are denominated or a combination of
money or government obligations that through the payment of interest on and
principal of such government obligations in accordance with their terms will
provide money in an amount sufficient to pay all the principal of, premium, if
any, and interest on the Debt Securities of such series on the dates such
payments are due (up to the stated maturity date, or the redemption date, as
the case may be) in accordance with the terms of such Debt Securities. Such a
trust may only be established if, among other things, (a) no Event of Default
described under "Events of Default" shall have occurred and be continuing and
(b) the Company shall have delivered an opinion of counsel to the effect that
(i) the holders of the Debt Securities will not recognize gain or loss for
United States federal income tax purposes as a result of such deposit or
defeasance and will be subject to United States federal income tax in the same
manner as if such defeasance had not occurred, and (ii) the trust resulting
from the deposit does not constitute, or is qualified as, a regulated
investment company under the Investment Company Act of 1940. Such opinion, in
the case of defeasance under clause (i) above, must refer to and be based upon
a ruling of the Internal Revenue Service or a change in applicable federal
income tax law occurring after the date of the applicable Indenture. In the
event the Company fails to comply with its remaining obligations under the
applicable Indenture after a defeasance of such Indenture with respect to the
Debt Securities of any series as described under clause (ii) above and the
Debt Securities of such series are declared due and payable because of the
occurrence of any undefeased Event of Default, the amount of money and
government obligations on deposit with the applicable Trustee may be
insufficient to pay amounts due on the Debt Securities of such series at the
time of the acceleration resulting from such Event of Default. However, the
Company will remain liable in respect of such payments.
 
  Notwithstanding the description set forth under "Subordination of Senior
Subordinated Securities and Subordinated Securities" above, in the event that
the Company deposits money or government obligations in compliance with the
Indenture that governs any Senior Subordinated Securities or Subordinated
Securities, as the case may be, in order to defease all or certain of its
obligations with respect to the applicable series of Debt Securities, the
money or government obligations so deposited will not be subject to the
subordination provisions of the applicable Indenture, and the indebtedness
evidenced by such series of Debt Securities will not be subordinated in right
of payment to the holders of applicable Senior Indebtedness to the extent of
the money or government obligations so deposited.
 
THE TRUSTEES
 
  Each Indenture will provide that, except during the continuance of an Event
of Default, the Trustee thereunder will perform only such duties as are
specifically set forth in the Indenture. If an Event of Default occurs and is
continuing, the Trustee will exercise such rights and powers vested in it
under the Indenture and use the same degree of care and skill in its exercise
as a prudent Person would exercise under the circumstances in the conduct of
such Person's own affairs.
 
  Each Indenture will, and provisions of the Trust Indenture Act of 1939, as
amended, contain limitations on the rights of the Trustee thereunder, should
it become a creditor of the Company, to obtain payment of claims in certain
cases or to realize on certain property received by it in respect of any such
claims, as security or otherwise. The Trustee is permitted to engage in other
transactions; provided, however, that if it acquires any conflicting interest
(as defined) it must eliminate such conflict or resign.
   
FORM, EXCHANGE, REGISTRATION AND TRANSFER     
 
  Debt Securities are issuable in definitive form or in temporary or permanent
global form.
 
                                      14
<PAGE>
 
  Debt Securities of any series will be exchangeable for other Debt Securities
of the same series and of a like aggregate principal amount and tenor of
different authorized denominations.
 
  Debt Securities may be presented for exchange, as provided above, and for
registration of transfer (with the form of transfer endorsed thereon duly
executed), at the office or agency of the Company maintained for such purposes
and at any other office or agency maintained for such purpose with respect to
any series of Debt Securities and referred to in the applicable Prospectus
Supplement, without a service charge and upon payment of any taxes and other
governmental charges as described in the applicable Indenture. Such transfer
or exchange will be effected upon the satisfaction of the Company or its
agent, as the case may be, with the documents of title and identity of the
person making the request.
 
  In the event of any redemption in part, the Company will not be required to
(i) issue, register the transfer of or exchange Debt Securities of any series
during a period beginning at the opening of business 15 days prior to the
selection of Debt Securities of that series for redemption and ending on the
close of business on the day of mailing of the relevant notice of redemption;
or (ii) register the transfer of or exchange any Debt Security, or portion
thereof, called for redemption, except the unredeemed portion of any Debt
Security being redeemed in part.
 
PAYMENT AND PAYING AGENTS
 
  Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of, premium, if any, and interest on Debt Securities will be made
in the designated currency or currency unit at the office of such Paying Agent
or Paying Agents as the Company may designate from time to time, except that
at the option of the Company payment of any interest may be made by check
mailed to the address of the person entitled thereto at the address in the
Security Register. Unless otherwise indicated in an applicable Prospectus
Supplement, payment of any installment of interest on Debt Securities will be
made to the person in whose name such Debt Security is registered at the close
of business on the record date for such interest payment.
 
  Unless otherwise indicated in the applicable Prospectus Supplement, the
Corporate Trust Office of the Trustee will be designated as a Paying Agent for
the Trustee for payments with respect to Debt Securities. Any other Paying
Agents will be named in an applicable Prospectus Supplement. The Company may
at any time designate additional Paying Agents or rescind the designation of
any Paying Agent or approve a change in the office through which any Paying
Agent acts, except that the Company will be required to maintain a Paying
Agent in each place of payment for each series of Debt Securities.
 
  All monies paid by the Company to a Paying Agent for the payment of
principal of and any premium or interest on any Debt Security that remain
unclaimed at the end of two years after such principal, premium or interest
shall have become due and payable will (subject to applicable escheat laws) be
repaid to the Company, and the holder of such Debt Security or any coupon will
thereafter look only to the Company for payment thereof.
 
TEMPORARY GLOBAL SECURITIES
 
  If so specified in the applicable Prospectus Supplement, all or any portion
of the Debt Securities of a series which are sold in offshore transactions
initially may be represented by one or more temporary global Debt Securities,
without interest coupons, to be deposited with or on behalf of, and registered
in the name of, a depositary or its nominee (a "Depositary") identified in the
applicable Prospectus Supplement for credit to the purchasers' respective
accounts at Morgan Guaranty Trust Company of New York, Brussels office, as
operator of the Euroclear System ("Euroclear") and Cedel, societe anonyme
("Cedel"). On and after the date determined as provided in any such temporary
global Debt Security and described in the applicable Prospectus Supplement,
each such temporary global Debt Security will be exchangeable for definitive
Debt Securities or all or a portion of a permanent global security, or any
combination thereof, as specified in the applicable Prospectus Supplement.
 
                                      15
<PAGE>
 
PERMANENT GLOBAL SECURITIES
 
  If any Debt Securities of a series are issuable in permanent global form as
a Global Security, the applicable Prospectus Supplement will describe the
circumstances, if any, under which beneficial owners of interests in any such
Global Security may exchange such interests for Debt Securities of such series
in definitive form of like tenor and principal amount in any authorized
denomination.
 
BOOK-ENTRY DEBT SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on
behalf of, a Depositary or its nominee identified in the applicable Prospectus
Supplement. In such a 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 Debt Securities of the series to be
represented by such Global Security or Securities. Unless and until it is
exchanged in whole or in part for Debt Securities in registered form, a Global
Security may not be registered for transfer or exchange 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 nominee to a successor Depositary or a
nominee of such successor Depositary and except in the circumstances described
in the applicable Prospectus Supplement.
 
  The specific terms of the depository arrangement with respect to any portion
of a series of Debt Securities to be represented by a Global Security will be
described in the applicable Prospectus Supplement. The Company expects that
the following provisions will apply to depository arrangements.
 
  Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities which are to be represented by a Global Security to be deposited
with or on behalf of a Depositary will be represented by a Global Security
registered in the name of such Depositary. Upon the issuance and deposit with
or on behalf of the Depositary of such Global Security, the Depositary will
credit, on its book-entry registration and transfer system, the respective
principal amounts of the Debt Securities represented by such Global Security
to the accounts of institutions that have accounts with such Depositary or its
nominee ("participants"). The accounts to be credited will be designated by
the underwriters or agents of such Debt Securities or by the Company, if such
Debt Securities are offered and sold directly by the Company. Ownership of
beneficial interest in such Global Security will be limited to participants or
persons that may hold interests through participants. Ownership of beneficial
interests by participants in such Global Security will be shown on, and the
transfer of that ownership interest will be effected only through, records
maintained by the Depositary for such Global Security. Ownership of beneficial
interests in such Global Security by persons that hold through participants
will be shown on, and the transfer of that ownership interest within such
participant will be effected only through, records maintained by such
participant. The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. The
foregoing limitations and such laws may impair the ability to transfer
beneficial interests in such Global Securities.
 
  So long as the Depositary for a Global Security is the registered owner of
such Global Security, such Depositary will be considered the sole owner or
holder of the Debt Securities represented by such Global Security for all
purposes under the applicable Indenture. Unless otherwise specified in the
applicable Prospectus Supplement, owners of beneficial interests in such
Global Security will not be entitled to have Debt Securities of the series
represented by such Global Security registered in their names, will not
receive or be entitled to receive physical delivery of Debt Securities of such
series in definitive form and will not be considered the holders thereof for
any purposes under the applicable Indenture. Accordingly, each person owning a
beneficial interest in such Global Security must rely on the procedures of the
Depositary and, if such person is not a participant, on the procedures of the
participant through which such person owns its interest, to exercise any
rights of a holder under the applicable Indenture. The Company understands
that under existing industry practices, if the Company requests any action of
holders, or an owner of a beneficial interest in such Global Security desires
to give any notice or take any action a holder is entitled to give or take
under an Indenture, the Depositary would authorize
 
                                      16
<PAGE>
 
the participants to give such notice or take such action, and participants
would authorize beneficial owners owning through such participants to give
such notice or take such action or would otherwise act upon the instructions
of beneficial owners owning through them.
 
  Principal of and any premium and interest on a Global Security will be
payable in the manner described in the applicable Prospectus Supplement.

                        DESCRIPTION OF PREFERRED STOCK
 
  The Company's Restated Certificate of Incorporation authorizes 25,000,000
shares of preferred stock, par value $0.01 per share. Preferred Stock may be
issued from time to time in one or more classes or series, without stockholder
approval. Subject to limitations prescribed by law, the Board of Directors of
the Company is authorized to determine the different classes and/or series of
Preferred Stock and the powers, preferences and rights thereof.
   
  The Company currently has one series of Preferred Stock outstanding,
designated as Series A Convertible Preferred Stock (the "Series A Preferred
Stock"). As of March 23, 1998, there were 1,138,729 shares of Series A
Preferred Stock outstanding that are listed on the New York Stock Exchange and
trade under the symbol "XTOpA." The Series A Preferred Stock ranks prior to
all shares of Common Stock as to payment of dividends and liquidation
distributions and provides for a liquidation preference of $25.00 per share
and cumulative dividends of $1.5625 per share per year. The Series A Preferred
Stock is subject to redemption by the Company under certain conditions and is
convertible into Common Stock at the rate of 2.16 shares of Common Stock (as
adjusted for the three-for-two stock split distributed on February 25, 1998)
for each share of Series A Preferred Stock. Holders of Series A Preferred
Stock are entitled to vote (1) with the holders of Common Stock the number of
votes equal to the number of shares of Common Stock into which such Series A
Preferred Stock is convertible and (2) separately as a class to elect two
additional directors if Series A Preferred Stock dividends are in arrears for
at least six quarters.     
 
  The following is a description of certain general terms and provisions of
Preferred Stock that may be offered hereby. The particular terms of any series
of Preferred Stock will be described in the applicable Prospectus Supplement.
If so indicated in a Prospectus Supplement, the terms of any such series may
differ from the terms set forth below. Certain provisions applicable to the
Company's Common Stock are set forth below in "Description of Common Stock."
 
  The summary of terms of the Company's preferred stock (including the
Preferred Stock) contained in this Prospectus does not purport to be complete
and is subject to, and qualified in its entirety by, the provisions of the
Company's Restated Certificate of Incorporation and the certificate of
designations relating to each class or series of Preferred Stock, which will
be filed as an exhibit to or incorporated by reference in the Registration
Statement of which this Prospectus is a part at or prior to the time of
issuance of such series of the Preferred Stock.
 
  The Preferred Stock will have the dividend, liquidation, redemption and
voting rights set forth below unless otherwise provided in a Prospectus
Supplement relating to a particular series of Preferred Stock.
 
  The applicable Prospectus Supplement will describe the following terms of
the series of Preferred Stock in respect of which this Prospectus is being
delivered: (1) the designation and stated value, if any, per share of such
Preferred Stock and the number of shares offered; (2) the amount of
liquidation preference per share and any priority relative to any other class
or series of Preferred Stock or Common Stock; (3) the initial public offering
price at which such Preferred Stock will be issued; (4) the dividend rate or,
if applicable, any index or formula used to determine the amount of dividends
payable, the dates on which dividends shall be payable and the dates from
which dividends will commence to cumulate, if any; (5) any redemption or
sinking fund provisions; (6) any conversion or exchange rights; (7) any voting
rights; and (8) other rights, preferences, privileges, limitations and
restrictions.
 
GENERAL
 
  The Preferred Stock offered hereby will be issued in one or more classes or
series. The holders of Preferred Stock will have no preemptive rights.
Preferred Stock, upon issuance against full payment of the purchase price
therefor, will be fully paid and nonassessable. Neither the par value nor the
liquidation preference is indicative of the price at which the Preferred Stock
will actually trade on or after the date of issuance.
 
                                      19
<PAGE>
 
RANK
 
  Unless otherwise specified in the applicable Prospectus Supplement, the
Preferred Stock will, with respect to dividend rights and rights on
liquidation, winding up and dissolution of the Company, rank prior to the
Company's Common Stock and to all other classes and series of equity
securities of the Company now or hereafter authorized, issued or outstanding
(the Common Stock and such other classes and series of equity securities
collectively may be referred to herein as the "Junior Stock"), other than any
classes or series of equity securities of the Company ranking on a parity with
(the "Parity Stock") or senior to (the "Senior Stock") the Preferred Stock as
to dividend rights and rights upon liquidation, winding up or dissolution of
the Company. The Preferred Stock will be junior to all outstanding debt of the
Company. The Preferred Stock will be subject to creation of Senior Stock,
Parity Stock and Junior Stock to the extent not expressly prohibited by the
Company's Restated Certificate of Incorporation.
 
DIVIDENDS
 
  Holders of shares of Preferred Stock will be entitled to receive, when, as
and if declared by the Board of Directors out of funds of the Company legally
available for payment, cash dividends, payable at such dates and at such rates
per share per annum as set forth in the applicable Prospectus Supplement. Such
rate may be fixed or variable or both. Each declared dividend will be payable
to holders of record as they appear at the close of business on the stock
books of the Company on such record dates, not more than 60 calendar days
preceding the payment dates therefor, as are determined by the Board of
Directors.
 
  Such dividends may be cumulative or noncumulative, as provided in the
Prospectus Supplement. If dividends on a class or series of Preferred Stock
are noncumulative and if the Board of Directors fails to declare a dividend in
respect of a dividend period with respect to such class or series, then
holders of such Preferred Stock will have no right to receive a dividend in
respect of such dividend period, and the Company will have no obligation to
pay the dividend for such period, whether or not dividends are declared
payable on any future dates. Dividends on the shares of each class or series
of Preferred Stock for which dividends are cumulative will accrue from the
date on which the Company initially issues shares of such class or series.
 
  No full dividends will be declared or paid or set apart for payment on
Parity Stock or Junior Stock for any period unless full dividends for the
immediately preceding dividend period on the Preferred Stock offered hereby
and by the applicable Prospectus Supplement (including any accumulation in
respect of unpaid dividends for prior dividend periods, if dividends on such
Preferred Stock are cumulative) have been paid or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for such payment. When dividends are not so paid in full (or a sum
sufficient for such full payment is not so set apart) upon such Preferred
Stock and any Parity Stock, dividends upon shares of such Preferred Stock and
dividends on such Parity Stock shall be declared pro rata so that the amount
of dividends declared per share on such Preferred Stock and such Parity Stock
shall in all cases bear to each other the same ratio that accrued dividends
for the then-current dividend period per share on the shares of such Preferred
Stock (including any accumulation in respect of unpaid dividends for prior
dividend periods, if dividends on such Preferred Stock are cumulative) and
accrued dividends, including required or permitted accumulations, if any, on
shares of such Parity Stock, bear to each other. Unless full dividends on such
Preferred Stock have been declared and paid or set apart for payment for the
immediately preceding dividend period (including any accumulation in respect
of unpaid dividends for prior dividend periods, if dividends on such Preferred
Stock are cumulative) (a) no cash dividend or distribution (other than in
shares of Junior Stock) may be declared, set aside or paid on the Junior
Stock, (b) the Company may not repurchase, redeem or otherwise acquire any
shares of its Junior Stock (except by conversion into or exchange for other
Junior Stock) and (c) the Company may not, directly or indirectly, repurchase,
redeem or otherwise acquire any shares of Preferred Stock or Parity Stock
otherwise than pursuant to certain pro rata offers to purchase or a concurrent

CONVERTIBILITY
 
  The terms, if any, on which shares of Preferred Stock of any class or series
may be exchanged for or converted (mandatorily or otherwise) into shares of
Common Stock of the Company or another class or series of Preferred Stock or
other securities of the Company will be set forth in the Prospectus Supplement
relating thereto. See "Description of Common Stock."
 
REDEMPTION
 
  The terms, if any, on which shares of Preferred Stock of any class or series
may be redeemed will be set forth in the related Prospectus Supplement.
 
LIQUIDATION
 
  Unless otherwise specified in the applicable Prospectus Supplement, in the
event of a voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, the holders of a class or series of Preferred
Stock will be entitled, subject to the rights of creditors, but before any
distribution or payment to the holders of Junior Stock, to receive an amount
per share as set forth in the related Prospectus Supplement plus accrued and
unpaid dividends for the then-current dividend period (including any
accumulation in respect of unpaid dividends for prior dividend periods, if
dividends on such class or series of Preferred Stock are cumulative). If the
amounts available for distribution with respect to the Preferred Stock and
Parity Stock upon liquidation are not sufficient to satisfy the full
liquidation rights of all the outstanding Preferred Stock and Parity Stock,
then the holders of such stock will share ratably in any such distribution of
assets in proportion to the full respective preferential amount to which they
are entitled. After payment of the full amount of the liquidation preference,
unless otherwise specified in the applicable Prospectus Supplement, the
holders of shares of Preferred Stock will not be entitled to any further
participation in any distribution of assets by the Company.
 
VOTING
 
  The Preferred Stock of a class or series will be entitled to vote only as
specified in the applicable Prospectus Supplement and as required by
applicable law. Unless otherwise specified in the related Prospectus
Supplement, the Preferred Stock will have the following rights. At any time
dividends in an amount equal to six quarterly dividend payments on the
Preferred Stock shall have accrued and be unpaid, holders of the Preferred
Stock shall have the right to a separate class vote (together with the holders
of shares of any Parity Stock upon which like voting rights have been
conferred and are exercisable, "Voting Parity Stock") to elect two additional
members of the Board of Directors of the Company at any meeting of
stockholders at which directors are elected that is held during the period
such dividends remain in arrears. The right of holders of Voting Parity Stock
to elect such two additional directors and the term of office of such
additional directors will terminate at the time that all accrued and unpaid
dividends on such Voting Parity Stock shall be declared and paid or set apart
for payment. If the right to elect such two additional directors shall accrue
more than 90 days before the date established for the next annual meeting of
stockholders, the Chairman of the Board of the Company shall call a special
meeting of holders of Voting Parity Stock within 20 days after a written
request therefor signed by holders of at least 10% of such Voting Parity Stock
outstanding is received by the Company. Additionally, without the affirmative
vote of the holders of two-thirds of the shares of Preferred Stock then
outstanding (voting separately as a class together with any Voting Parity
Stock), the Company may not, either directly or indirectly or through merger
or consolidation with any other corporation, (i) approve the authorization,
creation or issuance, or an increase in the authorized or issued amount, of
any class or series of stock ranking prior to the shares of Preferred Stock in
rights and preferences or (ii) amend, alter or repeal its Restated Certificate
of Incorporation or the Certificate of Designations so as to materially and
adversely change the specific terms of the Preferred Stock. An amendment that
increases the number of authorized shares of or authorizes the creation or
issuance of other Parity Stock or Junior Stock, or substitutes the surviving
entity in a merger, consolidation, reorganization or other business
combination for the Company, will not be considered to be such an adverse
change.

NO OTHER RIGHTS

special rights except as set forth above or in the related Prospectus
Supplement, the Restated Certificate of Incorporation and in the certificate of
designations or as otherwise required by law.

                             PLAN OF DISTRIBUTION
 
  The Company may offer Securities to or through underwriters, through agents
or dealers or directly to other purchasers. The applicable Prospectus
Supplement will set forth the names of any underwriters or agents and the
amount of Securities, if any, to be purchased by such underwriters or sold
through such agents.
 
  The distribution of 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, at prices related to such market prices
or at negotiated prices.
 
  In connection with the sale of Securities, underwriters or agents may
receive compensation from the Company or from purchasers in the form of
discounts, concessions or commissions. Underwriters, agents and dealers
participating in the distribution of the Securities may be deemed to be
underwriters within the meaning of the Securities Act.

underwriters or agents named in the applicable Prospectus Supplement, such
underwriters or agents may be entitled to indemnification by the Company
against certain liabilities, including liabilities under the Securities Act.

issue Securities to or through underwriters, agents or dealers in connection
with the conversion or redemption of its outstanding securities.

future date. Institutions with which such contracts may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and others, but shall in

of delivery be prohibited by the laws of any jurisdiction in the United States
to which such institution is subject, and (ii) if a portion of the Securities
is being sold to underwriters, the Company shall have sold to such
underwriters the Securities not sold for delayed delivery. Underwriters and
such other persons will not have any responsibility in respect of the validity
or performance of such contracts.
 
  Although the Company has previously issued debt securities, preferred stock,
common stock and warrants to purchase Common Stock, any Debt Securities,
Preferred Stock, Common Stock and Warrants offered may be a new issue of
securities with no established trading market. Any underwriters to whom such
Debt Securities, Preferred Stock and Warrants are sold by the Company for
public offering and sale may make a market in such Debt Securities, Preferred
Stock and Warrants, 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 or the trading markets for any Debt
Securities, Preferred Stock or Warrants.
 
  Certain of the underwriters or agents and their associates may be customers

ordinary course of business.

incorporated by reference herein in reliance upon the authority of said firm
as experts with respect to the matters contained in such reports.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company is incorporated in Delaware. Under Section 145 of the Delaware
General Corporation Law (the "DGCL"), a Delaware corporation has the power,
under specified circumstances, to indemnify its directors, officers, employees
and agents in connection with actions, suits or proceedings brought against
them by a third party or in the right of the corporation, by reason of the
fact that they were or are such directors, officers, employees or agents,
against expenses and liabilities incurred in any such action, suit or
proceeding so long as they acted in good faith and in a manner that they
reasonably believed to be in, or not opposed to, the best interests of such
corporation, and with respect to any criminal action, that they had no
reasonable cause to believe their conduct was unlawful. With respect to suits
by or in the right of such corporation, however, indemnification is generally
limited to attorneys' fees and other expenses and is not available if such
person is adjudged to be liable to such corporation unless the court
determines that indemnification is appropriate. A Delaware corporation also
has the power to purchase and maintain insurance for such persons. Article
Nine of the Restated Certificate of Incorporation of the Company permits
indemnification of directors and officers to the fullest extent permitted by
Section 145 of the DGCL. Reference is made to the Restated Certificate of
Incorporation of the Company.
 
  Additionally, the Company has acquired directors and officers insurance in
the amount of $10,000,000, which includes coverage for liability under the
federal securities laws.
 
  Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may contain a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director provided that such provisions may not
eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) under Section 174 (relating to liability for
unauthorized acquisitions or redemptions of, or dividends on, capital stock)
of the DGCL or (iv) for any transaction from which the director derived an
improper personal benefit. Article Ten of the Company's Restated Certificate
of Incorporation contains such a provision.
 
  The above discussion of the Company's Restated Certificate of Incorporation
and Sections 102(b)(7) and 145 of the DGCL is not intended to be exhaustive
and is qualified in its entirety by such Restated Certificate of Incorporation
and statutes.

    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement; notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement; and
 
      (iii) to include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;
 
                                     II-2
<PAGE>
 
  provided, however, that paragraphs (a)(i) and (a)(ii) 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, that are incorporated by reference in the Registration Statement;
 
    (b) That for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new Registration Statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof; and
 
    (c) 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.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.
 
  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 the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Trust
Indenture Act.

     Maturity or which shall be deemed to be Outstanding as of any date (or, in
     any such case, the manner in which such principal amount shall be
     determined);

     Security in addition to or in lieu of that set forth in Section 2.16 and
     any circumstances other than those set forth in Section 2.07 in which any
     such Global Security may be transferred to, and registered and exchanged

     such transfer may be registered;

     any change in the right of the Trustee or the Holders to declare the
     principal of, and premium and interest on, such Securities due and payable;

          (x) provisions, if any, regarding the appointment by the Trustee of an
     authenticating agent in one or more places other than the location of the
     office of the Trustee with power to act on behalf of the Trustee and
     subject to its direction in the authentication and delivery of the

          (y) the provisions for the payment of any additional amounts, to the

          (z) whether the provisions of Section 4.02 shall apply in respect of

          (aa) any other terms of the series, which shall not be inconsistent
     with the provisions of this Indenture.

     All Securities of any one series shall be substantially identical except as
to denomination and except as may otherwise be provided in or pursuant to the
Board Resolutions of the Company referred to above and set forth, or determined
in the manner provided, in the Officers' Certificate referred to above or in any
such indenture supplemental hereto.  All Securities of any one series need not
be issued at the same time and, unless otherwise provided, a series may be
reopened for issuances of additional Securities of such series.

     If any of the terms of the series are established by action taken pursuant
to Board Resolutions of the Company, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificates setting forth the terms of the series.

      SECTION 2.03. EXECUTION OF SECURITIES. The Securities shall be signed on
behalf of the Company by its Chairman of the Board, its Chief Executive Officer
or a Vice President and by its Secretary, an Assistant Secretary, a Treasurer or
an Assistant Treasurer. Such signatures upon the Securities may be the manual or
facsimile signatures of the present or any future such authorized officers and
may be imprinted or otherwise reproduced on the

                                       15
<PAGE>
 
Securities. The seal of the Company, if any, may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the
Securities.

     Only such Securities as shall bear thereon a certificate of authentication
substantially in the form hereinafter recited, signed manually by the Trustee,
shall be entitled to the benefits of this Indenture or be valid or obligatory
for any purpose. Such certificate by the Trustee upon any Security executed by
the Company shall be conclusive evidence that the Security so authenticated has
been duly authenticated and delivered hereunder.

     In case any officer of the Company who shall have signed any of the
Securities shall cease to be such officer before the Securities so signed shall
have been authenticated and delivered by the Trustee, or disposed of by the
Company, such Securities nevertheless may be authenticated and delivered or
disposed of as though the Person who signed such Securities had not ceased to be
such officer of the Company; and any Security may be signed on behalf of the
Company by such Persons as, at the actual date of the execution of such
Security, shall be the proper officers of the Company, although at the date of
such Security or of the execution of this Indenture any such Person was not such
officer.

      SECTION 2.04. AUTHENTICATION AND DELIVERY OF SECURITIES. At any time and
from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
deliver said Securities to or upon an Order by the Company. In authenticating
such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and (subject to Section 7.01) shall be fully protected in relying upon:

          (1) a copy of any resolution or resolutions of the Board of Directors,
     certified by the Secretary or Assistant Secretary of the Company,
     authorizing the terms of issuance of any series of Securities;

          (2) an executed supplemental Indenture, if any;

          (3)  an Officers' Certificate; and

          (4) an Opinion of Counsel prepared in accordance with Section 13.01
     which shall also state that the form of such Securities has been
     established by or pursuant to a resolution of the Board of Directors or by
     a supplemental Indenture as permitted by Section 2.02 in conformity with
     the provisions of this Indenture.

     A Security shall not be valid until an authorized signatory of the Trustee
manually signs the certificate of authentication on the Security. The signature
shall be conclusive evidence that the Security has been authenticated under this
Indenture.

     The Trustee may appoint an authenticating agent reasonably acceptable to
the Company to authenticate Securities of any series. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An

                                       16
<PAGE>

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 Security for any series, each
Security shall be dated the date of its authentication.

     SECTION 2.05. DENOMINATION OF SECURITIES. Unless otherwise provided in the
form of Security for any series, the Securities of each series shall be issuable
only as Registered Securities in such denominations as shall be specified or
contemplated by Section 2.02. In the absence of any such specification with
respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 and any integral multiple thereof.

     SECTION 2.06. REGISTRAR AND PAYING AGENT. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer
or for exchange (the "REGISTRAR") and an office or agency where Securities may
be presented for payment (the "PAYING AGENT"). 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". The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Company may have one or more co-registrars and one or
more additional paying agents; PROVIDED, HOWEVER, that so long as
____________________ shall be the Trustee, without the consent of the Trustee,
there shall be no more than one Registrar or Paying Agent. The term "PAYING
AGENT" includes any additional paying agent.

     The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the names and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.06. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

     SECTION 2.07. REGISTRATION OF TRANSFER AND EXCHANGE.

          (a) The Company shall keep or cause to be kept a register for each
     series of Securities issued hereunder (hereinafter collectively referred to
     as the "Security Register"), in which, subject to such reasonable
     regulations as it may prescribe, the Company shall provide for the
     registration of Securities and the transfer of Securities as in this
     Article 2 provided. At all reasonable times the Security Register shall be
     open for inspection by the Trustee. The Trustee shall preserve in as
     current a form as is reasonably practicable the most recent list available
     to it of the names and addresses of Holders. If the Trustee is not the
     Registrar, the Company shall furnish to the Trustee, in writing at least
     five Business Days before each Interest Payment Date and at such other
     times as the Trustee may request in writing, a list in such form and as of
     such date as the Trustee may reasonably require of the names and addresses
     of Holders. Subject

                                       17
<PAGE>
 
     to Section 2.16, upon due presentment for registration of transfer of any
     Security at any office or agency to be maintained by the Company in
     accordance with the provisions of Section 4.03, the Company shall execute
     and the Trustee shall authenticate and deliver in the name of the
     transferee or transferees a new Security or Securities of authorized
     denominations for a like aggregate principal amount.

       Securities of any series (other than a Global Security, except as set
     forth below) may be exchanged for a like aggregate principal amount of
     Securities of the same series of other authorized denominations. Subject to
     Section 2.16, Securities to be exchanged shall be surrendered at the office
     or agency to be maintained by the Company as provided in Section 4.03, and
     the Company shall execute and the Trustee shall authenticate and deliver in
     exchange therefor the Security or Securities which the Holder making the
     exchange shall be entitled to receive.

           Whenever any Securities are so surrendered for exchange, the Company
     shall execute, and the Trustee shall authenticate and deliver, the
     Securities that the Holder making the exchange is entitled to receive.

          (b) All 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 Holder or his attorney
     duly authorized in writing.

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

          No service charge shall be made for any exchange or registration of
     transfer of 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 Securities for a period of 15 days next preceding any
     mailing of notice of redemption of Securities of such series or (b) to
     register the transfer of or exchange any Securities selected, called or
     being called for redemption.

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

                                       18
<PAGE>
 
          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 SECURITIES. Pending the preparation of definitive
Securities of any series, the Company may execute and the Trustee shall
authenticate and deliver temporary Securities (printed, lithographed,
photocopied, typewritten or otherwise produced) of any authorized denomination,
and substantially in the form of the definitive Securities in lieu of which they
are issued, in registered form, and with such omissions, insertions and
variations as may be appropriate for temporary Securities, all as may be
determined by the Company with the concurrence of the Trustee.  Temporary
Securities may contain such reference to any provisions of this Indenture as may
be appropriate.  Every temporary 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 Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company at a Place of Payment for such series, without
charge to the Holder thereof, except as provided in Section 2.07 in connection
with a transfer upon surrender for cancellation of any one or more temporary
Securities of any series, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor. Until so exchanged, temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

     Upon any exchange of a portion of a temporary Global Security for a
definitive Global Security or for the individual 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 SECURITIES. If (i) any
mutilated 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 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 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, if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Security, a new Security of the same series of like
tenor, form, terms and principal amount, bearing a number not 

                                       19
<PAGE>
 
contemporaneously Outstanding, and neither gain nor loss in interest shall
result from such exchange or substitution. If required by the Trustee or the
Company, such Holder shall furnish an indemnity bond sufficient in the judgment
of the Company and the Trustee to protect the Company, the Trustee, the Paying
Agent, the Registrar and any co-registrar from any loss which any of them may
suffer if a Security is replaced. Upon the issuance of any substituted 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 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
Security, pay or authorize the payment of the same (without surrender thereof
except in the case of a mutilated 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 Security and of the
ownership thereof.

     Every substituted Security of any series issued pursuant to the provisions
of this Section 2.09 by virtue of the fact that any Security is destroyed, lost
or stolen shall constitute an original additional contractual obligation of the
Company, whether or not the destroyed, lost or stolen 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 Securities of that series duly issued
hereunder. All 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 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 SECURITIES.  The Company at any
time may deliver Securities to the Trustee for cancellation. All 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 Securities shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture. The Trustee and
no one else shall cancel and destroy (subject to the record retention
requirements of the Exchange Act) all Securities surrendered for registration of
transfer, exchange, payment or cancellation and certification of their
destruction shall be delivered to the Company, unless otherwise directed. On
request of the Company, the Trustee shall deliver to the Company canceled
Securities held by the Trustee. If the Company shall acquire any of the
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 Securities to replace Securities it has redeemed, paid or
delivered to the Trustee for cancellation.

     SECTION 2.11. PROVISIONS OF THE INDENTURE AND SECURITIES FOR THE SOLE
BENEFIT OF THE PARTIES AND THE HOLDERS. Nothing in this Indenture or in the
Securities, expressed or implied, shall give or be construed to give to any
Person, other than the parties hereto, the Holders or any Registrar or Paying
Agent, any legal or equitable right, 

                                       20
<PAGE>
 
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.

     SECTION 2.12. PAYING AGENT TO HOLD MONEY IN TRUST. Prior to each due date
of the principal and interest on any Security, the Company shall deposit with
the Paying Agent a sum sufficient to pay such principal and interest when so
becoming due. The Paying Agent shall hold in trust for the benefit of Holders or
the Trustee all money held by the Paying Agent for the payment of principal of
or interest on the Securities and shall notify the Trustee of any default by the
Company in making any such payment. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate the money held by it as Paying Agent to pay all
money held by it to the Trustee and to account for any funds disbursed by the
Paying Agent. Upon complying with this Section, the Paying Agent shall have no
further liability for the money delivered to the Trustee.

     SECTION 2.13. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

          (a) Interest on any 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 Security upon any transfer or exchange subsequent to
     the Regular Record Date. Payment of interest on Securities shall be made at
     the Corporate Trust Office of the Trustee (except as otherwise specified
     pursuant to Section 2.02), 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 Security Register or, if provided pursuant to Section 2.02 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 clause (a) of this Section 2.13 and Section 2.17,
     each Security of a particular series delivered under this Indenture upon
     registration of transfer of or in exchange for or in lieu of any other
     Security of the same series shall carry the rights to interest accrued and
     unpaid, and to accrue, which were carried by such other Security.

     SECTION 2.14. SECURITIES DENOMINATED IN FOREIGN CURRENCIES.

          (a) Payment of the principal of, and premium, if any, and interest on,
     Securities of any series denominated in any Currency will be made in such
     Currency.

          (b) Unless Securities of any Series are denominated in a Currency,
     payment of the principal of, and premium, if any, and interest on,
     Registered Securities of such series will be made in Dollars.

          (c) For the purposes of calculating the principal amount of Securities
     of any series denominated in a Foreign Currency or Foreign Currencies
     (including European Currency Units) for any purpose under this Indenture,
     the principal amount of such 

                                       21
<PAGE>
 
     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 in which any payment
     with respect to any series of 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 Securities of a series is due, the Company shall select
     the Currency of payment for use on such date, all as provided in the
     Securities of such series. In such event, the Company shall, as provided in
     the 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 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 2.15. 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 Securities (whether pursuant to optional or mandatory
redemption payments, interest payments or otherwise) by wire transfer in
immediately available funds to an account designated by the Trustee on or before
the date such monies are to be paid to the Holders of the Securities in
accordance with the terms hereof.

     SECTION 2.16. SECURITIES ISSUABLE IN THE FORM OF A GLOBAL SECURITY.

          (a) If the Company shall establish pursuant to Section 2.02 that the
     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 2.04,
     authenticate and deliver, such Global Security or Securities, which (i)
     shall represent, and shall be denominated in an amount equal to the
     aggregate principal amount of, the Outstanding Securities of such series to
     be represented by such Global Security or Securities, or such portion
     thereof as the Company shall specify in an Officer's Certificate, (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 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 2.16 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 

                                       22
<PAGE>
 
     in part for definitive 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 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 Securities of such series in exchange for such Global
     Security, will authenticate and deliver, individual 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 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 Securities of such series in
     exchange in whole or in part for such Global Security, will authenticate
     and deliver individual 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 2.02 with
     respect to 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 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 Securities of such series
     shall authenticate and deliver, without service charge, (1) to each Person
     specified by such Depositary a new 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 

                                       23
<PAGE>
 
     surrendered Global Security and the aggregate principal amount of
     Securities delivered to Holders thereof.

               (iv) In any exchange provided for in this subsection (c), the
     Company will execute and the Trustee or its agent will authenticate and
     deliver individual Securities.  Upon the exchange of the entire principal
     amount of a Global Security for individual Securities, such Global Security
     shall be canceled by the Trustee or its agent. Except as provided in
     subsection (c)(iii), Registered Securities issued in exchange for a Global
     Security pursuant to this Section 2.16 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
     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 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 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 Securities to be issued).

     SECTION 2.17. DEFAULTED INTEREST.

          Any interest on any 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 Securities of such series and in this Indenture
     (herein called "Defaulted Interest") shall forthwith cease to be payable to
     the Registered 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:

                                       24
<PAGE>
 
               (i) The Company may elect to make payment of any Defaulted
          Interest to the Persons in whose names the 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
          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 pre-paid, to each Holder thereof at its
          address as it appears in the Security Register, not less than 10 days
          prior to such special record date.  Notice of the proposed payment of
          such Defaulted Interest and the special record date therefor having
          been so mailed, such Defaulted Interest shall be paid to the Persons
          in whose names the Securities 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 2.02
for 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 Securities of
any series in a Foreign Currency or Dollars (the "Designated Currency") as may
be specified pursuant to Section 2.02 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 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 of 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 

                                       25
<PAGE>
 
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.

     SECTION 2.19. CUSIP NUMBERS.  The Company in issuing the Securities of any
series may use "CUSIP" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; PROVIDED, HOWEVER, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

     SECTION 2.20. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. The
Trustee's Certificate of Authentication on all Securities authenticated by the
Trustee shall be in substantially the following form:

                    TRUSTEE'S CERTIFICATE OF AUTHENTICATION

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

                                       As Trustee


                                       By
                                         ----------------------------------
                                         Authorized Signature


                                   ARTICLE 3

                                   REDEMPTION

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

     SECTION 3.02. NOTICES TO TRUSTEE.  If the Company elects to redeem all or
any part of the Securities of any series in accordance with their terms, it
shall notify the Trustee in writing of the redemption date, the principal amount
of Securities to be redeemed and the series and terms of the Securities pursuant
to which the redemption will occur.

     The Company shall give each notice to the Trustee provided for in this
Section at least 45 days before the redemption date unless the Trustee consents
to a shorter period. Such notice 

                                       26
<PAGE>
 
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.

     SECTION 3.03. SELECTION OF SECURITIES TO BE REDEEMED.  If fewer than all
the Securities of a series are to be redeemed, the Trustee shall select the
Securities of such series to be redeemed pro rata or by lot or by a method that
complies with applicable legal and securities exchange requirements, if any, and
that the Trustee considers fair and appropriate and in accordance with methods
generally used at the time of selection by fiduciaries in similar circumstances.
The Trustee shall make the selection from outstanding Securities of such series
not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities of such series that have denominations
larger than $1,000. Securities and portions of them that the Trustee selects
shall be in amounts of $1,000 or a whole multiple of $1,000. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption. The Trustee shall notify the Company
promptly of the Securities or portions of Securities to be redeemed.

     SECTION 3.04. NOTICE OF REDEMPTION.  At least 30 days but not more than 60
days before a date for redemption of Securities of any series, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities of
such series to be redeemed.

     The notice shall identify the Securities to be redeemed and shall state:

     (1)  the redemption date;

     (2)  the redemption price;

     (3) the name and address of the Paying Agent where payment will be made
upon presentation and surrender of Securities;

     (4) that Securities called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (5) the terms of the Securities of that series pursuant to which the
Securities of that series are being redeemed;

     (6) if fewer than all the outstanding Securities are to be redeemed, the
identification and principal amounts of the particular Securities to be
redeemed;

     (7) that, unless the Company defaults in making such redemption payment or
the Paying Agent is prohibited from making such payment pursuant to the terms of
this Indenture, interest on Securities (or portion thereof) called for
redemption ceases to accrue on and after the redemption date, and, in the case
of Original Issue Discount Securities, original issue discount accrued after the
date fixed for redemption will cease to accrue; and

     (8) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Securities.

                                       27
<PAGE>
 
     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense. In such event, the Company
shall provide the Trustee with the information required by this Section at least
45 days before the redemption date.

     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 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 Security of such series.

     SECTION 3.05. EFFECT OF NOTICE OF REDEMPTION.  Once notice of redemption
is mailed, Securities of a series called for redemption become due and payable
on the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date. If any
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 Securities
of that series.

     SECTION 3.06. DEPOSIT OF REDEMPTION PRICE.  Prior to the redemption date,
the Company shall deposit with the Paying Agent (or, if the Company or a
Subsidiary is the Paying Agent, shall segregate and hold in trust) money in the
Currency in which such Securities are denominated sufficient to pay the
redemption price of and accrued interest on all Securities to be redeemed on
that date other than Securities or portions of Securities called for redemption
which have been delivered by the Company to the Trustee for cancellation.

     SECTION 3.07. SECURITIES REDEEMED IN PART. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate for the Holder (at the Company's expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered.

     SECTION 3.08. MANDATORY AND OPTIONAL SINKING FUNDS. The minimum amount of
any sinking fund payment provided for by the terms of 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 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 Securities of a series in cash, the Company may at its
option (a) deliver to the Trustee Securities of that series theretofore
purchased or otherwise acquired by the Company or (b) receive credit for the
principal amount of Securities of that series which have been redeemed either at
the election of the Company pursuant to the terms of such Securities or through
the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, resolution or supplemental Indenture; PROVIDED, that
such Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the redemption price
specified in such Securities, resolution or supplemental Indenture for

                                       28
<PAGE>
 
redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

     SECTION 3.09. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60
days prior to each sinking fund payment date for any series of 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, any resolution or supplemental Indenture, the portion
thereof, if any, which is to be satisfied by payment of cash in the Currency in
which the Securities of such series are denominated (except as provided pursuant
to Section 2.02) and the portion thereof, if any, which is to be satisfied by
delivering and crediting Securities of that series pursuant to this Section 3.09
(which Securities, if not previously redeemed, will accompany such certificate)
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 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 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 Securities subject to a mandatory sinking fund payment
without the option to deliver or credit Securities as provided in this Section
3.09 and without the right to make any optional sinking fund payment, if any,
with respect to such series.

     The Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 3.03 and the Company shall
cause notice of the redemption thereof to be given in the manner provided in
Section 3.04 except that the notice of redemption shall also state that the
Securities are being redeemed by operation of the sinking fund. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in this Article 3.

                                   ARTICLE 4

                                   COVENANTS

     SECTION 4.01. PAYMENT OF SECURITIES. The Company shall promptly pay the
principal of and interest on the Securities of each series on the dates and in
the manner provided in the Securities and in this Indenture. Principal and
interest shall be considered paid on the date due if on such date the Trustee or
a Paying Agent holds in accordance with this Indenture money sufficient to pay
in the Currency in which the Securities of such series are denominated, all
principal and interest then due and, in the case of Securities subordinated
pursuant to the terms of Article 10, the Trustee or the 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 this Indenture.

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

     SECTION 4.02. CHANGE OF CONTROL.

     obligated to make an offer to purchase (a "Change of Control Offer") all of
     the then outstanding Securities, in whole or in part, from the Holders of
     such Securities in integral multiples of $1,000, at a purchase price (the
     "Change of Control Purchase Price") equal to 101% of the aggregate
     principal amount of such Securities, plus accrued and unpaid interest, if
     any, to the Change of Control Purchase Date (as defined below), in
     accordance with the procedures set forth in paragraphs (b), (c) and (d) of
     this Section. The Company shall, subject to the provisions described below,
     be required to purchase all securities properly tendered into the Change of
     Control Offer and not withdrawn. The Company will not be required to make a
     Change of Control Offer upon a Change of Control if a third party makes a
     Change of Control Offer at the same purchase price, at the same times and
     otherwise in substantial compliance with the requirements applicable to a
     Change of Control Offer made by the Company and purchases all Securities
     validly tendered and not withdrawn under such Change of Control Offer.

          (b) The Change of Control Offer is required to remain open for at
     least 20 Business Days and until the close of business on the fifth
     Business Day prior to the Change of Control Purchase Date (as defined
     below).

          (c) Not later than the 30th day following any Change of Control, the
     Company shall give to the Trustee in the manner provided in Section 13.05
     and each Holder of the Securities in the manner provided in Section 13.05,
     a notice (the "Change of Control Notice") stating:

               (1) that a Change in Control has occurred and that such Holder
          has the right to require the Company to repurchase such Holder's
          Securities, or portion thereof, at the Change of Control Purchase
          Price;

               (2) any information regarding such Change of Control required to
          be furnished pursuant to Rule 14e-1 under the Exchange Act and any
          other securities laws and regulations thereunder;

               (3) a purchase date (the "Change of Control Purchase Date") which
          shall be on a Business Day and no earlier than 30 days nor later than
          70 days from the date the Change of Control occurred;

               (4) that any Security, or portion thereof, not tendered or
          accepted for payment will continue to accrue interest;

               (5) that unless the Company defaults in depositing money with the
          Paying Agent in accordance with the last paragraph of clause (d) of
          this Section 4.02, or payment is otherwise prevented, any Security, or
          portion thereof, accepted for payment pursuant to the Change of
          Control Offer shall cease to accrue interest after the Change of
          Control Purchase Date; and

                                       30
<PAGE>
 
               (6) the instructions a Holder must follow in order to have its
          Securities repurchased in accordance with paragraph (d) of this
          Section.

          (d) Holders electing to have Securities purchased will be required to
     surrender such Securities to the Company at the address specified in the
     Change of Control Notice at least five Business Days prior to the Change of
     Control Purchase Date.  Holders will be entitled to withdraw their election
     if the Company receives, not later than three Business Days prior to the
     Change of Control Purchase Date, a facsimile transmission or letter setting
     forth the name of the Holder, the certificate number(s) and principal
     amount of the Securities delivered for purchase by the Holder as to which
     his election is to be withdrawn and a statement that such Holder is
     withdrawing his election to have such Securities purchased.  Holders whose
     Securities are purchased only in part will be issued new Securities equal
     in principal amount to the unpurchased portion of the Securities
     surrendered.

     SECTION 4.03. MAINTENANCE OF OFFICE OR AGENCY. The Company shall maintain
in each Place of Payment for any series of Securities an office or agency where
Securities of such series may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities of such
series and this Indenture may be served. The Company shall 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 its agent to receive all presentations, surrenders, notices
and demands.

     The Company may also from time to time designate one or more different or
additional offices or agencies (in or outside of The City of New York) where
Securities may be presented or surrendered for any or all of such purposes, and
may from time to time rescind such designations; PROVIDED that no such
designation or rescission shall in any manner relieve the Company of its
obligations described in the preceding paragraph. The Company shall give prompt
written notice to the Trustee of any such designation and any change in the
location of any such other office or agency.

     SECTION 4.04. MONEY FOR THE SECURITY PAYMENTS TO BE HELD IN TRUST. If the
Company, any Subsidiary of the Company or any of their respective Affiliates
shall at any time act as Paying Agent with respect to the Securities of any
series, such Paying Agent shall, on or before each due date of the principal of
(and premium, if any) or interest on any of the Securities, segregate and hold
in trust for the benefit of the Persons entitled thereto money sufficient to pay
the principal (and premium, if any) or interest so becoming due until such money
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents with respect to
the Securities, it shall, prior to or on each due date of the principal of (and
premium, if any) or interest on any of the Securities, deposit with a Paying
Agent a sum sufficient to pay the 

                                       31
<PAGE>
 
principal (and premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Paying Agent shall
promptly notify the Trustee of the Company's action or failure so to act.

     Any funds deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or
interest on any Securities and remaining unclaimed for two years after the date
upon which such payment shall have become due, shall be paid to the Company on
Order or, if then held by the Company, shall be discharged from such trust;
PROVIDED, HOWEVER, that the Company shall cause to be published at least once in
a newspaper of general circulation in The City of New York or mailed to each
Holder entitled to such unclaimed funds, notice that such funds remain unclaimed
and that, after a date specified therein, which shall be a date not less than 30
days from the date of such publication or mailing, any unclaimed balance of such
money remaining as of such date shall be repaid to the Company. After repayment
to the Company, Holders entitled to such funds shall look only to the Company
for payment without interest thereon, as an unsecured general creditor, and the
Trustee and the Paying Agent shall have no further liability with respect to
such trust money, and the Company shall not be a trustee in respect of such
funds.

     SECTION 4.05. PAYMENT OF TAXES AND OTHER CLAIMS. The Company shall pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all material taxes, assessments and governmental charges levied
or imposed upon the Company or any of its Subsidiaries or upon the income,
profits or property of the Company or any of its Subsidiaries and (b) all
material lawful claims for labor, materials and supplies which, if unpaid, might
by law become a Lien upon the property of the Company or any of its
Subsidiaries; PROVIDED 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 and for which adequate reserves in accordance with
GAAP or other appropriate provision has been made.

occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with TIA (S) 314(a)(4).

     SECTION 4.08. FURTHER INSTRUMENTS AND ACTS.  Upon request of the Trustee,
the Company will execute and deliver such further instruments and do such
further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

     transaction or series of transactions on a pro forma basis (and treating
     any Indebtedness not previously an obligation of the Company which becomes
     the obligation of the Company in connection with or as a result of such

                             DEFAULTS AND REMEDIES

     SECTION 6.01. EVENTS OF DEFAULT. Whenever used herein, an "EVENT OF
DEFAULT" means any one of the following events (whatever the reason for such

          (e) a court of competent jurisdiction enters an order or decree under

          thereof;

          and the order or decree remains unstayed and in effect for 60 days.

     SECTION 6.02. ACCELERATION. If an Event of Default (other than an Event of
Default described in clause (d) or (e) above) with respect to Securities of a
series at the time Outstanding shall occur and be continuing, either the Trustee
or the Holders of at least 25% in aggregate principal amount of the Outstanding
Securities of that series by written notice may declare the principal amount of
the Securities of that series (or, if the Securities of that series are Original
Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of that series) and interest on all the Securities of
that series to be due and payable immediately. If an Event of Default described
in clause (d) or (e) above with respect to the Securities of a series at the
time Outstanding shall occur, the principal amount (or, if the Securities of
that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) and interest
on all the Securities of that series will automatically, and without any action
by the Trustee or any Holder, become immediately due and payable.

     After any such acceleration, but before a judgment or decree based on
acceleration, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of that series may rescind and annul such acceleration if

                                       35
<PAGE>
 
          (a) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

               (i) all money paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursement and advances of the
          Trustee, its agents and counsel,

               (ii) all overdue installments of interest on all Securities of
          such series;

               (iii)  the principal of (and premium, if any, on ) any Securities
          of such series that have become due otherwise than by such declaration
          of acceleration and interest thereon at the rate or rates prescribed
          therefor in the Securities of such series, and

               (iv) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate prescribed therefor in the
          Securities of such series;

          (b) all Events of Default, other than the nonpayment of principal of
     Securities which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 6.04;

          (c) the annulment of such acceleration would not conflict with any
     judgment or decree of a court of competent jurisdiction; and

          (d) the Company has delivered an Officers' Certificate to the Trustee
     to the effect of clauses (b) and (c) of this sentence.

     No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

     SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities of a series or to enforce the
performance of any provision of the Securities of such series or this Indenture.

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

     SECTION 6.04. WAIVER OF PAST DEFAULTS. The Holders of a majority in
principal amount of the Securities of a series by notice to the Trustee may
waive an existing Default and its consequences except (i) a Default in the
payment of the principal of or interest on a Security of such series or (ii) a
Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Holder affected. When a Default is waived, it 

                                       36
<PAGE>
 
is deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

     SECTION 6.05. CONTROL BY MAJORITY. The Holders of a majority in principal
amount of the Securities of a series may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Holders, it being understood that the Trustee shall have no
duty to ascertain whether or not such actions or forbearances are unduly
prejudiced to such Holders, or would involve the Trustee in personal liability;
PROVIDED, HOWEVER, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory
to it in its sole discretion against all losses and expenses caused by taking or
not taking such action.

     SECTION 6.06. LIMITATION ON SUITS. No Holder of any Securities of any
series shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or a
trustee, or for any other remedy hereunder, unless:

               (i)   such Holder has previously given to the Trustee written
          notice of a continuing Event of Default with respect to a series of
          Securities;

               (ii)  the Holders of at least 25% in aggregate principal amount
          of the Outstanding Securities of such Series have made written
          request, and such Holder or Holders have offered reasonable indemnity,
          to the Trustee to institute such proceeding as trustee; and

               (iii) the Trustee has failed to institute such proceeding, and
          has not received from the Holders of a majority in aggregate principal
          amount of the Outstanding Securities of such series a direction
          inconsistent with such request, within 60 days after such notice,
          request and offer.

     A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over another Holder.

     SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.  Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal of and interest on the Securities of any series held by such Holder,
on or after the respective due dates expressed in the Securities, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

     SECTION 6.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified
in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount then due and 

                                       37
<PAGE>
 
owing (together with interest on any unpaid interest to the extent lawful) and
the amounts provided for in Section 7.06.

     SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Holders allowed in any
judicial proceedings relative to the Company, its creditors or its property and,
unless prohibited by law or applicable regulations, may vote on behalf of the
Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and its counsel, and any other amounts due the Trustee under Section 7.06.

     SECTION 6.10. PRIORITIES. If the Trustee collects any money or property
pursuant to this Article 6, it shall pay out the money or property in the
following order, at the date or dates fixed by the Trustee for the distribution
of such monies or other property, upon presentation of the several Securities of
such series in respect of which monies 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 Trustee for amounts due under Section 7.06;

          [If applicable:  SECOND: to holders of Senior Indebtedness of the
     Company to the extent required by Article 10;]

          [If applicable:  THIRD: to holders of Senior Subordinated Indebtedness
     of the Company to the extent required by Article 10;]

          FOURTH:  In case the principal of the Outstanding Securities in
     respect of which such monies have been collected shall not have become due,
     to the payment of interest on the 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 Securities) borne by the Securities of such
     series, such payments to be made ratably to the Persons entitled thereto,
     without discrimination or preference;

          FIFTH: In case the principal of the Outstanding Securities in respect
     of which such monies have been collected shall have become due, by
     declaration or otherwise, to the payment of the whole amount then owing and
     unpaid upon the 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 Securities) borne by the
     Securities of such series; and, in case such monies shall be insufficient
     to pay in full the whole amount so due and 

                                       38
<PAGE>

     unpaid upon the 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 Security of such series over any
     Security of such series, ratably to the aggregate of such principal and
     premium, if any, and interest; and

          SIXTH: to the Company.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section. 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 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the Trustee
or a suit by a Holder pursuant to Section 6.07.

                                   ARTICLE 7

                                    TRUSTEE

     SECTION 7.01. DUTIES OF TRUSTEE.

          (a) If an Event of Default has occurred and is continuing, the Trustee
     shall exercise the rights and powers vested in it by this Indenture and use
     the same degree of care and skill in their exercise as a prudent Person
     would exercise or use under the circumstances in the conduct of such
     Person's own affairs.

          (b) Except during the continuance of an Event of Default:

               (1) the Trustee undertakes to perform such duties and only such
          duties as are specifically set forth in this Indenture and no implied
          covenants or obligations shall be read into this Indenture against the
          Trustee; and

               (2) in the absence of bad faith on its part, the Trustee may
          conclusively rely, as to the truth of the statements and the
          correctness of the opinions expressed therein, upon certificates or
          opinions furnished to the Trustee and conforming to the requirements
          of this Indenture. However, the Trustee shall examine the certificates
          and opinions to determine whether or not they conform to the
          requirements of this Indenture.

                                       39
<PAGE>
 
          (c) The Trustee may not be relieved from liability for its own
     negligent action, its own negligent failure to act or its own willful
     misconduct, except that:

               (1) this subsection does not limit the effect of subsection (b)
          of this Section;

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

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

          (d) Every provision of this Indenture that in any way relates to the
     Trustee is subject to subsections (a), (b) and (c) of this Section.

          (e) The Trustee shall not be liable for interest on any money received
     by it except as the Trustee may agree in writing with the Company.

          (f) Money held in trust by the Trustee need not be segregated from
     other funds except to the extent required by law.

          (g) No provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur financial liability in the
     performance of any of its duties hereunder or in the exercise of any of its
     rights or powers, if it shall have reasonable grounds to believe that
     repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (h) 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 and to the provisions of the
     Trust Indenture Act.

     SECTION 7.02. RIGHTS OF TRUSTEE.

          (a) The Trustee may rely on any document believed by it to be genuine
     and to have been signed or presented by the proper Person. The Trustee need
     not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate or an Opinion of Counsel. The Trustee shall not be
     liable for any action it takes or omits to take in good faith in reliance
     on the Officers' Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible
     for the misconduct or negligence of any agent appointed with due care.

                                       40
<PAGE>
 
          (d) The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it believes to be authorized or within its
     rights or powers; PROVIDED, HOWEVER, that the Trustee's conduct does not
     constitute willful misconduct or negligence.

          (e) The Trustee may consult with counsel, and the advice or opinion of
     counsel with respect to legal matters relating to this Indenture and the
     Securities shall be full and complete authorization and protection from
     liability in respect to any action taken, omitted or suffered by it
     hereunder in good faith and in accordance with the advice or opinion of
     such counsel.

          (f) Prior to the occurrence of an Event of Default hereunder and after
     the curing or waiving of all Events of Default, the Trustee shall not be
     bound to make any investigation into the facts or matters stated in any
     resolution, Officer's Certificate, or other certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     appraisal, bond, debenture, note, coupon, security, or other paper or
     document unless requested in writing to do so by the Holders of not less
     than a majority in aggregate principal amount of the Securities then
     outstanding; provided, 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, in the opinion of the Trustee, not
     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 expenses or liabilities as a condition to proceeding; the
     reasonable expenses of every such examination shall be paid by the Company
     or, if advanced by the Trustee, shall be repaid by the Company upon demand.

          (g) The Trustee shall not be required to give any bond or surety in
     respect of the performance of its powers and duties hereunder.

          (h) The Trustee shall not be bound to ascertain or inquire as to the
     performance or observance of any covenants, conditions, or agreements on
     the part of the Company, except as otherwise set forth herein, but the
     Trustee may require of the Company full information and advice as to the
     performance of the covenants, conditions and agreements contained herein
     and shall be entitled in connection herewith to examine the books, records
     and premises of the Company.

          (i) The permissive rights of the Trustee to do things enumerated in
     this Indenture shall not be construed as a duty.

          (j) Except for (i) a default under Section 6.01(a) or (b) hereof, or
     (ii) any other event of which the Trustee has "actual knowledge" and which
     event, with the giving of notice or the passage of time or both, would
     constitute an Event of Default under this Indenture, the Trustee shall not
     be deemed to have notice of any Default or Event of Default unless
     specifically notified in writing of such event by the Company or the
     Holders of not less than 25% in aggregate principal amount of the relevant
     series of Securities then Outstanding; as used herein, the term "actual
     knowledge" means the 

                                       41
<PAGE>
 
     actual fact or statement of knowing, without any duty to make any
     investigation with regard thereto.

     SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-
paying agent may do the same with like rights. However, the Trustee must comply
with Sections 7.09 and 7.10.

     SECTION 7.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Securities, it shall not be accountable for the Company's use of the
proceeds from the Securities, and it shall not be responsible for any statement
of the Company in this Indenture or in any document issued in connection with
the sale of the Securities of any series or in the Securities of any series
other than the Trustee's certificate of authentication.

     SECTION 7.05. NOTICE OF DEFAULTS. If a Default occurs and is continuing
and if it is known to the Trustee, the Trustee shall mail to each Holder notice
of the Default within 90 days after it occurs. Except in the case of a Default
in payment of principal of or interest on any Security (including payments
pursuant to the mandatory redemption provisions of such Security, if any), the
Trustee may withhold the notice if and so long as the Trustee in good faith
determines that withholding the notice is in the interests of Holders.

     SECTION 7.06. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee promptly upon request from time to time the compensation for its
services as agreed to by the Trustee and the Company. The Trustee's compensation
shall not be limited by any law on compensation of a trustee of an express
trust. The Company shall reimburse the Trustee promptly upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to the compensation for its services. Such expenses
shall include the reasonable compensation and expenses, disbursements and
advances of the Trustee's agents, counsel, accountants and experts. The Company
shall indemnify the Trustee against any and all loss, liability or reasonable
expense (including reasonable attorneys' fees) incurred by it in connection with
the acceptance and administration of this trust and the performance of its
duties hereunder. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim and the Trustee may have separate counsel and the Company shall
pay the fees and expenses of such counsel. The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by the
Trustee through the Trustee's own willful misconduct, negligence or bad faith.
The Company need not pay for any settlement made by the Trustee without the
Company's consent, such consent not to be unreasonably withheld.

     To secure the Company's payment obligations in this Section, the Trustee
shall have a lien prior to the Securities on all money or property held or
collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.

                                       42
<PAGE>
 
     The Company's payment obligations pursuant to this Section shall survive
the discharge of this Indenture. When the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01 (d) or (e) with respect to the
Company, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law.

     SECTION 7.07. SEPARATE TRUSTEE; REPLACEMENT OF TRUSTEE. The Company may,
but need not, appoint a separate Trustee for any one or more series of
Securities. The Trustee may resign with respect to one or more or all series of
Securities at any time by notifying the Company. The Holders of a majority in
principal amount of the Securities of a particular series may remove the Trustee
for such series by notifying the Trustee and may appoint a successor Trustee.
The Company shall remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.09;

          (2) the Trustee is adjudged bankrupt or insolvent;

          (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 Securities of a particular series and 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.

     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 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 resigns or is removed, the retiring Trustee or the Holders of
10% in principal amount of the Securities of any applicable series may petition
any court of competent jurisdiction for the appointment of a successor Trustee
for the Securities of such series.

     If the Trustee fails to comply with Section 7.09, any Holder of Securities
of any applicable series may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee for the
Securities of such series.

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

                                       43
<PAGE>
 
     SECTION 7.08. SUCCESSOR TRUSTEE BY MERGER. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

     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 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 Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such 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 Securities or in this Indenture provided that the certificate of the
Trustee shall have.

     SECTION 7.09. ELIGIBILITY; DISQUALIFICATION. The Trustee shall at all
times satisfy the requirements of TIA Section 310(a). 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. The Trustee shall comply with TIA
Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) 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
TIA Section 310(b)(1) are met.

     SECTION 7.10. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.


                                   ARTICLE 8

              SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE

     SECTION 8.01. APPLICABILITY OF ARTICLE.  If, pursuant to Section 2.02,
provision is made for the defeasance of Securities of a series and if the
Securities of such series are denominated and payable only in Dollars (except as
provided pursuant to Section 2.02), then the provisions of this Article 8
relating to defeasance of Securities shall be applicable except as otherwise
specified pursuant to Section 2.02 for Securities of such series. Defeasance
provisions, if any, for Securities denominated in a Foreign Currency may be
specified pursuant to Section 2.02.

     SECTION 8.02. DISCHARGE OF LIABILITY ON SECURITIES.

          (a) When (i) the Company delivers to the Trustee all outstanding
     Securities of any series for cancellation (other than Securities replaced
     pursuant to Article 2 and Securities for whose payment money has
     theretofore been deposited in trust and 

                                       44
<PAGE>
 
     thereafter repaid to the Company as provided in Section 8.06), or (ii) all
     outstanding Securities of such series have become due and payable, whether
     at maturity or as a result of the mailing of a notice of redemption
     pursuant to Article 3 hereof and the Company irrevocably deposits with the
     Trustee cash in the Currency in which such Securities are denominated, U.S.
     Government Obligations or a combination thereof sufficient to pay at
     maturity or upon redemption all outstanding Securities of such series,
     including premium and interest thereon to maturity or such redemption date
     (other than Securities replaced pursuant to Article 2), and premium, if
     any, and if in either case the Company pays all other sums payable
     hereunder by the Company, then this Indenture shall, subject to Sections
     8.02(b), cease to be of further effect. The Trustee shall acknowledge
     satisfaction and discharge of this Indenture on demand of the Company
     accompanied by an Officers' Certificate and an Opinion of Counsel and at
     the cost and expense of the Company.

          (b) Notwithstanding subsection (a) above, the Company's obligations in
     Sections 2.06, 2.07, 2.09, 2.12, 7.06, 8.06, 8.07, 8.08 and 12.02 shall
     survive until the Securities of such series have been paid in full.
     Thereafter, the Company's obligations in Sections 8.06, 8.07 and 12.02
     shall survive.

     SECTION 8.03. DEFEASANCE.

          (a) Subject to Sections 8.03(d), 8.04 and 8.07, the Company at any
     time may terminate, with respect to Securities of a particular series, (i)
     all its obligations under the Securities of such series and this Indenture
     with respect to the Securities of such series ("LEGAL DEFEASANCE OPTION")
     or (ii) its obligations with respect to the Securities of such series under
     Sections 4.02, 4.05 and 12.03, and the operation of Sections 6.01(c),
     6.01(d), and 6.01(e) ("COVENANT DEFEASANCE OPTION"). The Company may
     exercise its legal defeasance option notwithstanding its prior exercise of
     its covenant defeasance option.

          (b) If the Company exercises its legal defeasance option, payment of
     the 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 Securities may not be accelerated because of an Event of
     Default specified in Sections 6.01(c), 6.01(d), and 6.01(e).

          (c) 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.

          (d) Notwithstanding subsection (a) above, the Company's obligations in
     Sections 2.06, 2.07, 2.09, 2.12, 7.06, 8.06, 8.07, 8.08 and 12.02 shall
     survive until the Securities of the defeased series have been paid in full.
     Thereafter, the Company's obligations in Section 8.06, 8.07 and 12.02 shall
     survive.

                                       45
<PAGE>
 
     SECTION 8.04. CONDITIONS TO DEFEASANCE. The Company may exercise its legal
defeasance option or its covenant defeasance option with respect to Securities
of a particular series only if:

          (1) the Company irrevocably deposits in trust with the Trustee cash in
     U.S. dollars, U.S. Government Obligations or a combination thereof for the
     payment of principal of, interest on and premium, if any, on the 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 principal, premium and interest
     when due on all the Securities of such series to maturity or redemption, as
     the case may be;

          (3) At the time the deposit is made no Default shall have occurred and
     be continuing;

          (4) the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article 10;

          (5) 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;

          (6) in the case 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, or there has been published by, 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 to the
     effect that, and based thereon such Opinion of Counsel shall confirm that,
     the Holders of 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;

          (7) in the case of the covenant defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of 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

          (8) the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that all conditions precedent to the
     defeasance and 

                                       46
<PAGE>
 
     discharge of the Securities of such series as contemplated by this Article
     8 have been complied with.

     Before or after a deposit, the Company may make arrangements satisfactory
to the Trustee for the redemption of Securities of such series at a future date
in accordance with Article 3.

     SECTION 8.05. APPLICATION OF TRUST MONEY. The Trustee shall hold in trust
money or U.S. Government Obligations deposited with it pursuant to this Article
8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal, premium and interest on the Securities of the defeased
series. In the event the Securities of the defeased series are subordinated
pursuant to Article 10, money and securities so held in trust are not subject to
Article 10.

     SECTION 8.06. REPAYMENT TO COMPANY. The Trustee and the Paying Agent shall
promptly turn over to the Company upon request any excess money or securities
held by them at any time.

     Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon Order any money held by them for the
payment of principal of, premium, if any, or interest on any Securities that
remains unclaimed for two years after the date upon which such payment shall
have become due; PROVIDED, HOWEVER, that the Company shall cause to be published
at least once in a newspaper of general circulation in The City of New York or
mailed to each Holder entitled to such unclaimed funds, notice that such funds
remain unclaimed and that, after a date specified therein, which shall be a date
not less than 30 days from the date of such publication or mailing, any
unclaimed balance of such money remaining as of such date shall be repaid to the
Company. After repayment to the Company, Holders entitled to such funds shall
look only to the Company for payment without interest thereon, as an unsecured
general creditor, and the Trustee and the Paying Agent shall have no further
liability with respect to such money.

     SECTION 8.07. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company shall pay
and shall indemnify the Trustee 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 8.08. REINSTATEMENT. If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with this Article 8
by reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company's obligations under this Indenture and the
Securities of the defeased series shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; PROVIDED, HOWEVER, that, if the
Company has made any payment of interest on or principal of Securities of the
defeased series because of the reinstatement of its obligations, 

                                       47
<PAGE>
 
the Company shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the money or U.S. Government Obligations held by
the Trustee or Paying Agent.

              (vi) to add guarantees by Subsidiary guarantors with respect to
          Securities of any series, or to secure the Securities pursuant to the

              (ix) to add to, change or eliminate any of the provisions of this
          Indenture in respect of one or more series of Securities; provided,
          however, that any such addition, change or elimination not otherwise
          permitted under this 

                                       48
<PAGE>
 
          Section 9.01 shall (i) neither (A) apply to any 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 Security with respect to such provision or (ii)
          shall become effective only when there is no such Security
          Outstanding;

              (x) to evidence and provide for the acceptance of appointment
          hereunder by a successor or separate Trustee with respect to the

          facilitate the administration of the trusts hereunder by more than one
          Trustee; and

              (xi) to establish the form or terms of Securities of any series
          as permitted by Section 2.02.

          (b) [Insert for Subordinated or Senior Subordinated Securities -- An
     amendment under this Section may not make any change that adversely affects
     the rights under Article 10 of any holder of Senior Indebtedness of the
     Company then outstanding unless the holders of such Senior Indebtedness (or
     any group or representative thereof authorized to give a consent) consent
     to such change in writing.]

          (c) After an amendment under this Section becomes effective, the
     Company shall mail to Holders a notice briefly describing such amendment.
     The failure to give such notice to all Holders, or any defect therein,
     shall not impair or affect the validity of an amendment under this Section.

     SECTION 9.02. WITH CONSENT OF HOLDERS.

          (a) The Company and the Trustee, with the written consent of the
     Holders of at least a majority of the principal amount of the Outstanding
     Securities of each series affected by such supplemental Indenture, may
     execute supplemental Indentures adding any provisions to or changing or
     eliminating any of the provisions of this Indenture or of any supplemental
     Indenture or modifying the rights of the Holders of the Securities of such
     series, except that no supplemental Indenture or waiver, without the
     consent of each Holder affected thereby, may:

              (i) reduce the principal amount of Securities of any series whose
          Holders must consent to an amendment or waiver;

              (ii) reduce the rate of or extend the time for payment of
          interest on any Securities;

              (iii)  change the Currency in which any amount due in respect of
          the Securities is payable from that stated in the Security;

                                       49
<PAGE>
 
              (iv) reduce the principal of or any premium on or change the
          Stated Maturity of any Securities or alter the redemption or
          repurchase provisions with respect thereto;

              (v) reduce the relative ranking of any Securities;

              (vi) release any security that may have been granted in respect
          of the Securities;

              (vii)  impair the right of any Holder to institute suit for
          enforcement of any payment on or with respect to such Holder's
          Securities; or

              (viii)  make any change in Sections 6.04, 6.07 or 9.02.

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

          (c) A supplemental Indenture under this Section may not make any
     change that adversely affects the rights under Article 10 of any holder of
     Senior Indebtedness of the Company then outstanding unless the holders of
     such Senior Indebtedness (or any group or representative thereof authorized
     to give a consent) consent to such change in writing.

          (d) After a supplemental Indenture under this Section becomes
     effective, the Company shall mail to Holders a notice briefly describing
     such supplemental Indenture. The failure to give such notice to all
     Holders, or any defect therein, shall not impair or affect the validity of
     a supplemental Indenture under this Section.

          (e) 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 Securities or
     which modifies the rights of the Holders of 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 Securities of any other
     series.

     SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every supplemental
Indenture or amendment to the Securities shall comply with the Trust Indenture
Act as then in effect.

     SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS AND WAIVERS.

          (a) A consent to a supplemental Indenture or a waiver by a Holder of a
     Security shall bind the Holder and every subsequent Holder of that Security
     or portion of the Security that evidences the same debt as the consenting
     Holder's Security, even if notation of the consent or waiver is not made on
     the Security. However, any such Holder or subsequent Holder may revoke the
     consent or waiver as to such Holder's Security or portion of the Security
     if the Trustee receives the notice of revocation before 

                                       50
<PAGE>
 
     the date the supplemental Indenture or waiver becomes effective. After a
     supplemental Indenture or waiver becomes effective, it shall bind every
     Holder. A supplemental Indentures or waiver becomes effective upon the
     execution of such supplemental Indenture or waiver by the Trustee.

          (b) The Company may, but shall not be obligated to, fix a record date
     for the purpose of determining the Holders entitled to give their consent
     or take any other action described above or required or permitted to be
     taken pursuant to this Indenture. If a record date is fixed, then
     notwithstanding the immediately preceding subsection, those Persons who
     were Holders 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 after such record date. No such consent
     shall be valid or effective for more than 120 days after such record date.

     SECTION 9.05. NOTATION ON OR EXCHANGE OF SECURITIES. If a supplemental
Indenture changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

     SECTION 9.06. TRUSTEE TO SIGN SUPPLEMENTAL INDENTURE. The Trustee shall
sign any supplemental Indenture authorized pursuant to this Article 9 if the
supplemental Indenture does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. If it does, the Trustee may but need not sign it.
In signing such supplemental Indenture, the Trustee shall be entitled to receive
indemnity reasonably satisfactory to it and to receive, and (subject to Section
7.01) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that such supplemental Indenture is authorized or
permitted by this Indenture.


                                  ARTICLE 10

                        SUBORDINATION OF THE SECURITIES

     SECTION 10.01. APPLICABILITY OF ARTICLE; AGREEMENT TO SUBORDINATE. The
provisions of this Article 10 shall be applicable to the Securities of any
series (Securities of such series referred to in this Article 10 as
"Subordinated Debt Securities") designated pursuant to Section 2.02 as
subordinated to Senior Indebtedness. Notwithstanding any other provision to the
contrary in this Indenture, the Company covenants and agrees, and each Holder by
accepting a Subordinated Debt Security covenants and agrees, that the principal
of (and premium, if any) and interest on the Indebtedness now or hereafter
evidenced by the Subordinated Debt Security and this Indenture are subordinated
in right of payment, to the extent and in the manner provided in this Article,
to the prior payment in full in cash of all existing 

                                       51
<PAGE>
 
and future Senior Indebtedness, and that the subordination provisions set forth
in this Article are for the benefit of, and shall be enforceable directly by,
the holders of Senior Indebtedness.

     Each Holder of a Subordinated Debt Securities authorizes and directs the
Trustee on such Holder's behalf to take such action as may be necessary or
appropriate, in the sole discretion of the Trustee, to acknowledge or effectuate
the subordination between the Holders and the holders of Senior Indebtedness as
provided in this Article and appoints the Trustee as such Holder's attorney-in-
fact for any and all such purposes, including, in the event of any voluntary or
involuntary liquidation or dissolution of the Company, whether total or partial,
or in a bankruptcy, reorganization, insolvency, receivership, dissolution,
assignment for the benefit of creditors, marshaling of assets or similar
proceeding relating to the Company or its property, the timely filing of a claim
for the unpaid balance of such Holder's Securities in the form required in said
proceeding and cause said claim to be approved. If the Trustee does not file a
proper claim or proof of debt in the form required in such proceeding prior to
20 days before the expiration of the time to file such claim or claims, then the
Principal Agent is hereby authorized to have the right to file and is hereby
authorized to file an appropriate claim for and on behalf of the Holders;
provided, however, that any such claim filed by the Principal Agent shall be
superseded by the claim, if any, subsequently filed by the Trustee.

     Each Holder of a Subordinated Debt Security by accepting a Security
acknowledges and agrees that the subordination provision set forth in this
Article are, and are intended to be, an inducement and consideration to each
holder of any Senior Indebtedness, whether such Senior Indebtedness was created
before or after the issuance of the 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 upon such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness, and such holder is made an obligee hereunder and may
enforce directly such subordination provisions.

     SECTION 10.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY. Upon any payment or
distribution (whether in cash, property, debt, equity or other securities, a
combination thereof or otherwise) to creditors or equity holders of the Company
in a voluntary or involuntary liquidation or dissolution of the Company, whether
total or partial, or in bankruptcy, reorganization, insolvency, receivership,
assignment for the benefit of creditors, marshaling of assets or similar
proceeding relating to the Company or its property:

          (a) holders of Senior Indebtedness shall be entitled to receive
     payment in full in cash of all amounts due or to become due on or in
     respect of all Senior Indebtedness before Holders of Subordinated Debt
     Securities shall be entitled to receive any Security Payment (as defined in
     Section 10.03(a)); and

          (b) until all Senior Indebtedness is paid in full in cash, any
     Security Payment (as defined in Section 10.03(a)) to which Holders of a
     Subordinated Debt Securities would be entitled but for this Article shall
     be made to holders of Senior Indebtedness, as their interests may appear.

          Upon any prepayment, payment or distribution referred to in this
     Article, the Trustee and the Holders shall be entitled to rely upon any
     order or decree of a court of 

                                       52
<PAGE>
 
     competent jurisdiction in which such proceedings are pending for the
     purpose of ascertaining the identity of Persons entitled to participate in
     such payment or distribution, the holders of Senior Indebtedness, the
     amount thereof or payable thereon and all other facts pertinent thereto or
     to this Article, and the Trustee and the Holders shall be entitled to rely
     upon a certificate of the liquidating trustee or agent or other Person
     (including any Representative of holders of Senior Indebtedness) making any
     payment or distribution to the Trustee or to the Holders for the purpose of
     ascertaining the identity of Persons entitled to participate in such
     payment or distribution, the holders of Senior Indebtedness, the amount
     thereof or payable thereon, the amount or amounts paid or distributed
     thereon and all other facts pertinent thereto or to this Article. In the
     event that the Trustee determines in good faith that further evidence is
     required with respect to the right of any Person, as a holder of Senior
     Indebtedness, to participate in any payment or distribution pursuant to
     this Section, the Trustee may require such Person (at the expense of the
     Holders) to furnish evidence to the reasonable satisfaction of the Trustee,
     acting in good faith, as to the amount of such Senior Indebtedness held by
     such Person, as to the extent to which such Person is entitled to
     participate in such payment or distribution, and as to other facts
     pertinent to the rights of such Person under this Section, 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
     payment.

          For purposes of this Article, a distribution may consist of cash,
     securities or other property, by set-off or otherwise; PROVIDED that, for
     purposes of this Article only, the words "cash, securities or other
     property" shall not be deemed to include securities of the Company or any
     other corporation ("REORGANIZATION SECURITIES") provided for by a plan of
     reorganization or readjustment of the Company the payment of which is
     subordinated, at least to the extent provided in this Article with respect
     to the Subordinated Debt Securities, to the payment of all Senior
     Indebtedness that may at the time be outstanding.

          The consolidation or merger of the Company with or into any Person, or
     the sale, assignment, transfer, lease, conveyance or other disposition of
     all or substantially all of the Company's assets to any Person, upon the
     terms and conditions set forth in Article 5, shall not be deemed to be
     liquidation, dissolution or reorganization or similar proceeding relating
     to the Company for purposes of this Section if the Person formed by or
     surviving such consolidation or merger, or to which such sale, assignment,
     transfer, lease, conveyance or other disposition is made, shall, as a part
     of such consolidation, merger, sale, assignment, transfer, lease,
     conveyance or other disposition, comply with the conditions set forth in
     Article 5.

     SECTION 10.03. DEFAULT ON SENIOR INDEBTEDNESS.

          (a) Upon any Senior Indebtedness becoming due and payable, whether at
     the stated maturity thereof or by acceleration or otherwise, such Senior
     Indebtedness shall first be irrevocably and indefeasibly paid in full in
     cash, or the immediate payment thereof duly provided for in cash, before
     the Company or any Person acting on behalf of the Company shall directly or
     indirectly pay, prepay, redeem, retire, repurchase or otherwise acquire for
     value, or make any deposit pursuant to Article 8 in respect of, or 

                                       53
<PAGE>
 
     make any other prepayment, payment or distribution (whether in cash,
     property, securities or a combination thereof or otherwise) on account of
     the principal of (or premium, if any) or interest on, any Subordinated Debt
     Securities (each, a "SECURITY PAYMENT").

          (b) If there exists a default in payment of all or any portion of any
     principal of (and premium, if any) and interest and fees, expenses, costs
     and other obligations on Senior Indebtedness, and (i) such default shall
     not have been cured or waived in writing or the benefits of this sentence
     waived in writing by or on behalf of the holders of such Senior
     Indebtedness or (ii) any judicial proceeding shall be pending with respect
     to any such default, then no Security Payment shall be made.

          (c) In addition, during the continuance of any event of default (other
     than a default referred to in subsection (b) of this Section 10.03) with
     respect to any Specified Senior Indebtedness, as such event of default is
     defined therein or in the instrument under which such Specified Senior
     Indebtedness is outstanding, permitting the holders of such Specified
     Senior Indebtedness to accelerate the maturity thereof under the terms of
     such Specified Senior Indebtedness, and upon written notice of such event
     of default given by the Principal Agent to the Trustee, with a copy to the
     Company (the delivery of such shall not affect the validity of the notice
     to the Trustee), then, unless and until such event of default shall have
     been cured or waived or shall have ceased to exist, no Security Payment
     shall be made; provided, that if the holders of the Specified Senior
     Indebtedness to which the default relates have not declared such Specified
     Senior Indebtedness to be immediately due and payable within 179 days after
     the occurrence of such default (or have declared such Specified Senior
     Indebtedness to be immediately due and payable and within such period have
     rescinded such declaration of acceleration), then, subject to the
     provisions of Section 10.02 and 10.03(a), the Company shall resume making
     any and all unpaid scheduled Security Payments. Any period during which any
     Security Payment is prohibited pursuant to the immediately preceding
     sentence is referred to in this Article as a "PAYMENT BLOCKAGE PERIOD."
     Notwithstanding any other provisions of this Article or any other provision
     of this Indenture, in no event shall a payment blockage period under this
     Article extend beyond 179 days from the date on which such payment blockage
     period commenced. Not more than one payment blockage period may be
     commenced within any consecutive 365-day period with respect to the
     Subordinated Debt Securities. For all purposes of this Article, no event of
     default that existed or was continuing on the date of the commencement of
     any payment blockage period with respect to the Specified Senior
     Indebtedness initiating such payment blockage period shall be, or be made,
     the basis for the commencement of a second payment blockage period by the
     holder or holders of such Specified Senior Indebtedness at any time after
     the 365-day period referred to in the previous sentence unless such event
     of default shall have been cured or waived for a period of not less than 90
     consecutive days.

          (d) The Company covenants that it will, upon request of the Trustee,
     deliver an Officers' Certificate (with copies thereof to the Representative
     of each class of Senior Indebtedness) showing in reasonable detail the
     Senior Indebtedness outstanding as of the date of such Officers'
     Certificate and the Representative of each class of Senior Indebtedness.
     The Trustee may conclusively rely thereon except to the extent that it
     shall 

                                       54
<PAGE>
 
     have received, from the Representative of any class of Senior Indebtedness,
     notice in writing controverting any of the statements made therein. Not
     less than 10 days prior to making any distribution in respect of Senior
     Indebtedness pursuant to this Section, the Trustee shall deliver to each
     Representative of any class of Senior Indebtedness copies of the most
     recent Officers' Certificate filed with it by the Company pursuant to this
     subsection (d).

     SECTION 10.04. SECURITY PAYMENTS PERMITTED IF NO DEFAULT. Nothing
contained in this Article or elsewhere in this Indenture, or in any of the
Subordinated Debt Securities, shall prevent the Company or any Person acting on
behalf of the Company, at any time except as otherwise provided in Sections
10.02 and 10.03 from making any Security Payment.

     SECTION 10.05. WHEN SECURITY PAYMENT MUST BE PAID OVER. In the event that
any Security Payment is made to the Trustee or the Holders of Subordinated Debt
Securities that, because of this Article, should not have been so made or may
not be paid over to the Holders, such Security Payment shall be held by the
Trustee or the Holders who receive such Security Payment, as the case may be,
for the benefit of, and shall forthwith be paid over or delivered to, the
holders of the Senior Indebtedness remaining unpaid or their Representatives, as
their interests may appear, to the extent necessary to irrevocably and
indefeasibly pay such Senior Indebtedness in full in cash in accordance with its
terms, after giving effect to any concurrent payment or distribution to or for
the holders of such Senior Indebtedness.

     SECTION 10.06. NOTICES BY THE COMPANY. The Company shall promptly notify
the Trustee, each Paying Agent and the Principal Agent of any facts known to the
Company that would cause a Security Payment to violate this Article, but failure
to give such notice shall not affect the subordination provided in this Article
of the Subordinated Debt Securities to Senior Indebtedness. Without limiting the
foregoing, if payment of the Subordinated Debt Securities is accelerated because
of an Event of Default, the Company shall promptly notify the Principal Agent of
the acceleration.

     SECTION 10.07. SUBROGATION. After all Senior Indebtedness is irrevocably
and indefeasibly paid in full in cash and until the Subordinated Debt Securities
are paid in full, Holders shall be subrogated to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to Holders have been applied to the
payment of Senior Indebtedness. A distribution made under this Article to
holders of Senior Indebtedness which otherwise would have been made to Holders
is not, as between the Company and the Holders, payment by the Company on Senior
Indebtedness.

     SECTION 10.08. RELATIVE RIGHTS. This Article defines the relative rights
of Holders of Subordinated Debt Securities and holders of Senior Indebtedness.
Nothing in this Indenture shall:

          (a) impair, as between the Company and the Holders of Subordinated
     Debt Securities, the obligation of the Company, which is absolute and
     unconditional, to pay 

                                       55
<PAGE>
 
     the principal of (and premium, if any) and interest on the Subordinated
     Debt Securities in accordance with their terms;

          (b) affect the relative rights of Holders of Subordinated Debt
     Securities and creditors of the Company other than holders of Senior
     Indebtedness; or

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

     If the Company fails because of this Article to pay the principal of (or
premium, if any) or interest on a Subordinated Debt Security on the due date or
upon the acceleration thereof, the failure is still a Default or Event of
Default.

     SECTION 10.09. SUBORDINATION MAY NOT BE IMPAIRED BY THE 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 (a) any act or failure to act by the Company or by its failure to
comply with this Indenture, (b) any release of any collateral or any Guarantor
of the Company's obligations under the Senior Indebtedness, (c) any amendment,
supplement, extension, renewal, restatement or other modification of the Senior
Indebtedness, (d) any settlement or compromise of any Senior Indebtedness, (e)
the unenforceability of any of the Senior Indebtedness or (f) the failure of any
holder of Senior Indebtedness to pursue claims against the Company.

     SECTION 10.10. DISTRIBUTION OF 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 10.11. RIGHTS OF TRUSTEE AND PAYING AGENT.  The Trustee or any
Payment Agent may continue to make payments in respect of the Subordinated Debt
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payment unless, not less than three
Business Days prior to the date of any such payment, a Responsible Officer of
the Trustee receives written notice reasonably satisfactory to it that payments
in respect of the Subordinated Debt Securities may not be made under this
Article. Only the Company, a Representative (satisfactorily identified to the
Trustee) or a holder of a class of Senior Indebtedness that has no
Representative (satisfactorily identified to the Trustee) may give the notice.
Prior to the receipt of such notice, the Trustee and any Paying Agent shall be
entitled in all respects to assume that no such facts exist. In any case, the
Trustee shall have no responsibility to the holders of Senior Indebtedness for
payments made to Holders by the Company or any Paying Agent unless cash payments
are made at the direction of the Trustee after receipt of such notice referred
to above.

     Neither the Trustee nor any Payment Agent shall be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness.

                                       56
<PAGE>
 
     The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have it were not Trustee.

     This Section is solely for the benefit of the Trustee and any Payment
Agents and shall not limit the obligations of the Holders under Section 10.05.

     SECTION 10.12. CONSENT OF HOLDERS OF SPECIFIED SENIOR INDEBTEDNESS. The
provisions of this Article (including the definitions contained in this Article
and references to this Article contained in this Indenture) shall not be
amended, waived or modified in a manner that would adversely affect the rights
of the holders of any Specified Senior Indebtedness, and no such amendment,
waiver or modification shall become effective, unless the holders of such
Specified Senior Indebtedness shall have consented in writing (in accordance
with the provisions of the agreement governing such Specified Senior
Indebtedness) to such amendment, waiver or modification.

     SECTION 10.13. CONTRACTUAL SUBORDINATION. This Article 10 represents a
bona fide agreement of contractual subordination pursuant to Section 510(b) of
the United States Bankruptcy Code.


                                  ARTICLE 11

                           CONVERSION OF SECURITIES

     SECTION 11.01. APPLICABILITY; CONVERSION PRIVILEGE AND CONVERSION PRICE.
If pursuant to a Board Resolution with respect to Securities of any series
denominated and payable in Dollars, Securities of such series may be convertible
into Common Stock of the Company, such conversion shall be in accordance with
the terms of such Board Resolution and (except as otherwise specified as
contemplated by Section 2.02 for Securities of any series) in accordance with
this Article. Conversion provisions, if any, for Securities denominated in a
Foreign Currency or for conversion into a security other than Company Common
Stock shall be specified pursuant to Section 2.02.

     Subject to and upon compliance with the provisions of this Article at the
option of the Holder thereof, any Security or any portion of the principal
amount thereof which is U.S. $1,000 or an integral multiple of U.S. $1,000
(unless otherwise specified in a Board Resolution or supplemental indenture with
respect to the Securities of the relevant series), may be converted at the
principal amount thereof, or of such portion thereof, into fully paid and non-
assessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100 of a share) of the Company, at the Conversion Price, determined as
hereinafter provided, in effect at the time of conversion. Such conversion right
shall expire at the close of business on the date specified for Securities of
such series. In case a Security or portion thereof is called for redemption,
such conversion right in respect of the Security or portion so called shall
expire at the close of business on the redemption date, unless the Company
defaults in making the payment due upon redemption.

                                       57
<PAGE>
 
     The price at which Common Stock shall be delivered upon conversion (the
"Conversion Price") shall initially be the price per share of Common Stock at
which the Securities of the relevant series are convertible as set forth in any
Board Resolution with respect to such series (or any supplemental indenture with
respect thereto). The Conversion Price shall be adjusted in certain instances as
provided in Section 11.04.

     SECTION 11.02. EXERCISE OF CONVERSION PRIVILEGE.  In order to exercise the
conversion privilege, the Holder of any Security to be converted shall surrender
such Security, duly endorsed or assigned to the Company or in blank, at any
office or agency of the Company maintained for that purpose pursuant to Section
4.04, accompanied by written notice to the Company (which shall be substantially
in the form set forth in the form of Security) at such office or agency or, if
applicable, by notice in accordance with specified procedures that the Holder
elects to convert such Security or, if less than the entire principal amount
thereof is to be converted, the portion thereof to be converted. Securities
surrendered for conversion during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except in the case of Securities
or portions thereof which have been called for redemption on a redemption date
within such period) be accompanied by payment in New York Clearing House funds
or other funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of Securities
being surrendered for conversion; PROVIDED, HOWEVER, that a Security surrendered
for conversion on an Interest Payment Date need not be accompanied by a payment,
and interest on the principal amount of the Securities being converted will be
paid on such Interest Payment Date, to the Holder of such Security on the
immediately preceding Record Date. Except as provided in the Securities, no
payment or adjustment shall be made upon any conversion on account of any
interest accrued on the Securities surrendered for conversion or on account of
any dividends on the Common Stock issued upon conversion.

     Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to received the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the date of conversion, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 11.03.

     All Securities converted in accordance with the provisions of this Article
11 are, and shall be deemed to have been, transferred to or for the account of
the Company.

     In the case of any Security which is converted in part only, upon such
conversion, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in aggregate principal amount equal to
the unconverted portion of the principal amount of such Security.

                                       58
<PAGE>
 
     SECTION 11.03. FRACTIONS OF SHARES. No fractional shares of Common Stock
or other such securities shall be issued upon conversion of Securities. If more
than one Security shall be surrendered for conversion at one time by the same
Holder, the number of full shares which shall be issuable upon conversion
thereof shall be computed on the basis of the aggregate principal amount of the
Securities (or specified portions thereof) so surrendered. Instead of any
fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay a cash adjustment in respect of such fraction in an amount
equal to the same fraction of the closing price per share of Common Stock at the
close of business on the day prior to the day of conversion on the New York
Stock Exchange or, if the Common Stock is not listed or admitted to trading on
such exchange, on the principal (as determined by the Company's Board of
Directors) U.S. securities exchange on which the Common Stock is listed or
admitted to trading or, if not listed or admitted to trading on any U.S.
securities exchange, on the National Association of Securities Dealers Automated
Quotations National Market System or, if the Common Stock is not listed or
admitted to trading on any U.S. securities exchange or quoted on such National
Market System, the average of the closing bid and asked prices in the over-the-
counter market as furnished by any New York Stock Exchange member firm selected
from time to time by the Company for that purpose.

     SECTION 11.04. ADJUSTMENT OF CONVERSION PRICE. The Conversion Price with
respect to any Security which is convertible into Common Stock shall be subject
to adjustment from time to time as follows:

          (a) If the Company shall pay or make a dividend or other distribution
     on any class of equity capital of the Company which is payable in Common
     Stock, the Conversion Price in effect at the opening of business on the day
     following the date fixed for the determination of stockholders entitled to
     receive such dividend or other distribution shall be reduced by multiplying
     such Conversion Price by a fraction of which (i) the numerator shall be the
     number of shares of Common Stock outstanding at the close of business on
     the date fixed for such determination and (ii) the denominator shall be the
     sum of such number of shares referred to in the preceding clause and the
     total number of shares constituting such dividend or other distribution,
     such reduction to become effective immediately after the opening of
     business on the day following the date fixed for such determination.

          (b) If the Company shall issue rights or warrants to all holders of
     its Common Stock entitling them to subscribe for or purchase Common Stock
     at a price per share less than the current market price per share of Common
     Stock (determined as provided in paragraph 11.04(d)) on the date fixed for
     the determination of stockholders entitled to receive such rights or
     warrants, the Conversion Price in effect at the opening of business on the
     day following the date fixed for such determination shall be reduced by
     multiplying such Conversion Price by a fraction of which (i) the numerator
     shall be the number of shares of Common Stock outstanding at the close of
     business on the date fixed for such determination plus the number of shares
     of Common Stock which the aggregate of the offering price of the total
     number of shares of Common Stock so offered for subscription or purchase
     would purchase at such current market price and (ii) the denominator shall
     be the number of shares of Common stock outstanding at the close of

                                       59
<PAGE>
 
     business on the date fixed for such determination plus the number of shares
     of Common Stock so offered for subscription or purchase, such reduction to
     become effective immediately after the opening of business on the day
     following the date fixed for such determination.

          (c) If outstanding shares of Common Stock shall be subdivided into a
     greater number of shares of Common Stock, the Conversion Price in effect at
     the opening of business on the day following the day upon which the
     subdivision becomes effective shall be proportionately reduced, and,
     conversely, in case outstanding shares of Common Stock shall be
     consolidated into a smaller number of shares of Common Stock, the
     Conversion Price in effect at the opening of business on the day following
     the day upon which such combination becomes effective shall be
     proportionately increased, such reduction or increase, as the case may be,
     to become effective immediately after the opening of business on the day
     following the day upon which such subdivision or consolidation becomes
     effective.

          (d) For the purpose of any computation under Section 11.03 and
     11.04(b), the current market price per share of Common Stock on any date
     shall be deemed to be the average of the daily closing prices for the five
     consecutive trading days selected by the Company commencing not more than
     20 trading days before, and ending not later than, the earlier of the day
     in question and the day before the "ex" date with respect to the issuance
     requiring such computation. The closing price for each day shall be the
     last reported sales price regular way or, in case no such reported sale
     takes place on such day, the average of the reported closing bid and asked
     prices regular way, in either case on the New York Stock Exchange or, if
     the Common Stock is not listed or admitted to trading on such exchange, on
     the principal (as determined by the Company's Board of Directors) U.S.
     securities exchange on which the Common Stock is listed or admitted to
     trading or, if not listed or admitted to trading on any U.S. securities
     exchange, on the National Association of Securities Dealers Automated
     Quotations National Market System or, if the Common Stock is not listed or
     admitted to trading on any U.S. securities exchange or quoted on such
     National Market System, the average of the closing bid and asked prices in
     the over-the-counter market as furnished by any New York Stock Exchange
     member firm selected from time to time by the Company for that purpose. For
     purposes of this paragraph, the term "ex date," when used with respect to
     any issuance means the first date on which the Common Stock trades regular
     way on such exchange or in such market without the right to receive such
     issuance or distribution.

          (e) The Company may make such reductions in the Conversion Price, in
     addition to those required by Sections 11.04(a) through 11.04(c), as it
     considers to be advisable in order that any event treated for the United
     States federal income tax purposes as a dividend of stock or stock rights
     shall not be taxable to the recipients. The Company shall have the power to
     resolve any ambiguity or correct any error in this paragraph 11.04(e) and
     its actions in so doing shall be final and conclusive.

          (f) No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least one
     percent in such price; PROVIDED, HOWEVER, that any adjustments which by
     reason of this paragraph 

                                       60
<PAGE>
 
     11.04(f) are not required to be made shall be carried forward and taken
     into account in any subsequent adjustment. All calculations under this
     Article shall be made to the nearest cent or to the nearest one-hundredth
     of a share, as the case may be.

          (g) For purposes of this Section, each Holder of Securities shall be
     deemed to have failed to exercise any right to elect the kind or amount of
     securities receivable upon the payment of any such dividend, subdivision,
     consolidation or reclassification (PROVIDED THAT if the kind or amount of
     securities receivable upon such dividend, subdivision, consolidation or
     reclassification for each non-electing share shall be deemed to be the kind
     and amount so receivable per share by a plurality of the non-electing
     shares).

     SECTION 11.05. NOTICE OF ADJUSTMENT OF CONVERSION PRICE. Whenever the
Conversion Price is adjusted as herein provided:

          (a) the Company shall compute the adjusted Conversion Price in
     accordance with Section 11.04 and shall prepare a certificate signed by an
     Officer of the Company setting forth the adjusted Conversion Price and
     showing in reasonable detail the facts upon which such adjustment is based,
     and such certificate shall forthwith be filed with the Trustee and at each
     office or agency maintained for the purpose of conversion of Securities
     pursuant to Section 4.03; and

          (b) a notice stating the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be required,
     and as soon as practicable after it is required, such notice shall be
     mailed by the Company to all Holders at their last addresses as they shall
     appear in the Security Register.

     SECTION 11.06. NOTICE OF CERTAIN CORPORATION ACTION.  In case:

          (a) the Company shall declare a dividend (or any other distribution)
     on its Common Stock payable otherwise than in cash out of its retained
     earnings; or

          (b) the Company shall authorize the granting to the holders of its
     Common Stock of rights or warrants to subscribe for or purchase any shares
     of equity capital of any class or of any other rights; or

          (c) the Company or any Subsidiary shall commence a tender offer or
     other offer to purchase any of its Common Stock; or

          (d) of any reclassification of the Common Stock of the Company (other
     than a subdivision or consolidation of its outstanding Common Stock), or of
     any consolidation or merger to which the Company is a party and for which
     approval of stockholders of the Company is required, or of the sale or
     transfer of all or substantially all of the assets of the Company; or

          (e) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company,

                                       61
<PAGE>
 
     then the Company shall cause to be filed at the Corporate Trust Office of
     the Trustee and at each office or agency maintained for the purpose of
     conversion of Securities pursuant to Section 4.05, and shall cause to be
     mailed to all Holders at their last addresses as they shall appear in the
     Security Register, at least 20 days (or 10 days in any case specified in
     clause (a) or (b) above) prior to the applicable record, effective or
     expiration date hereinafter specified, a notice stating (i) the date on
     which a record is to be taken for the purpose of such dividend,
     distribution, rights or warrants, or, if a record is not to be taken, the
     date as of which the holders of Common Stock of record to be entitled to
     such dividend, distribution, rights or warrants are to be determined, (ii)
     the date on which such reclassification, consolidation, merger, sale,
     transfer, dissolution, liquidation or winding up is expected to become
     effective, and the date as of which it is expected that holders of Common
     Stock of record shall be entitled to exchange their Common Stock for
     securities, cash or other property deliverable upon such reclassification
     consolidation, merger, sale, transfer, dissolution, liquidation or winding
     up, or (iii) the date on which such tender offer or other offer to purchase
     commenced, the date on which such tender offer or other offer to purchase
     is scheduled to expire unless extended, the consideration offered and the
     other material terms thereof (or the material terms of any amendment
     thereto). Neither the failure to give any such notice nor any defect
     therein shall affect the legality or validity of any action described in
     clauses (a) through (e) of this Section 11.06.

     SECTION 11.07. COMPANY TO RESERVE COMMON SHARES.  The Company shall at all
times reserve and keep available, free from pre-emptive rights, out of its
authorized but unissued Common Stock, for the purpose of effecting the
conversion of Securities, the number of its duly authorized shares of Common
Stock then issuable upon the conversion of all Outstanding Securities.

     SECTION 11.08. TAXES ON CONVERSION.  The Company will pay any and all
taxes that may be payable in respect of the issue or delivery of Common Stock on
conversion of Securities pursuant hereto. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issue and delivery of Common Stock in a name other than that of the
Holder of the Security or Securities to be converted, and no such issue or
delivery shall be made unless and until the Person requesting such issue has
paid to the Company the amount of any such tax, or has established to the
satisfaction of the Company that such tax has been paid.

     SECTION 11.09. COVENANT AS TO COMMON STOCK.  The Company covenants that
all Common Stock which may be issued upon conversion of Securities will upon
issue be fully paid and non-assessable and, except as provided in Section 11.08,
the Company will pay all taxes, liens and charges with respect to the issue
thereof.

     SECTION 11.10. COMPANY TO RECEIVE CONVERTED SECURITIES. All Securities
surrendered for conversion pursuant to Section 11.02 shall be delivered to the
Company.

     SECTION 11.11. PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF
ASSETS. In case of any consolidation of the Company with, or merger of the
Company into, any other corporation, any merger of another corporation into the
Company (other than a merger which does not result in any reclassification,
conversion, exchange or cancellation of 

                                       62
<PAGE>
 
outstanding Common Stock of the Company) or any sale or transfer of all or
substantially all of the assets of the Company (treating the Company and its
Subsidiaries as a single consolidated entity and treating any sale by a
Subsidiary as a sale by the Company for such purpose), the corporation formed by
such consolidation or resulting from such merger or which acquires such assets,
as the case may be, shall execute and deliver to the Trustee a supplemental
indenture providing that the Holder of each Security then outstanding shall have
the right thereafter, during the period such Security shall be convertible as
specified in Section 11.01, to convert such Security only into the kind and
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Common Stock of the Company into which such Security might have been converted
immediately prior to such consolidation, merger, sale or transfer, assuming such
holder of Common Stock of the Company (i) is not a Person with which the Company
consolidated or into which the Company merged or which merged into the Company
or to which such sale or transfer was made, as the case may be ("constituent
Person"), or an Affiliate of a constituent Person and (ii) failed to exercise
his rights of election, if any, as to the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer
(PROVIDED THAT if the kind or amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer by others than a
constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non-electing share"), then, for the
purpose of this Section, the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, sale or transfer by each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date
of such supplemental indenture, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article. The Trustee shall
not be under any responsibility to determine the correctness of any provision
contained in such supplemental indenture relating to either the kind or amount
of shares, other securities, cash or property receivable by Holders upon the
conversion of their Securities after any such consolidation, merger, sale or
transfer. The above provisions of this Section shall similarly apply to
successive consolidations, mergers, sales or transfers.

     SECTION 11.12. RESPONSIBILITY OF TRUSTEE AND CONVERSION AGENT. Neither the
Trustee nor any agent appointed to effect conversions shall at any time be under
any duty or responsibility to any Holder of Securities to determine whether any
facts exist which may require any adjustment of the Conversion Price, or with
respect to the nature or extent of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. Neither the Trustee nor any such
conversion agent shall be accountable with respect to the validity or value (or
the kind or amount) of any Common Stock or of any securities or property which
may at any time be issued or delivered upon the conversion of any Security; and
neither the Trustee nor any such conversion agent shall be responsible for any
failure of the Company to issue, transfer or deliver any Common Stock or stock
certificates or other securities or property or to make any cash payment upon
the delivery of any Security for the purpose of conversion or to comply with any
of the covenants contained in this Article.

               HOLDERS' LIST AND REPORTS BY TRUSTEE AND COMPANY

     SECTION 12.01  DISCLOSURE OF NAMES AND ADDRESSES OF HOLDERS. Every Holder
of Securities, by receiving and holding the same, agrees with the Company, the
Subsidiary Guarantors, if any, the Security Registrar and the Trustee that none
of the Company, the Subsidiary Guarantors, the Security Registrar or the
Trustee, or any agent of either of them, shall be held accountable by reason of
the disclosure of any such information as to the names and addresses of the
Holders in accordance with TIA Section 312, regardless of the source from which
such information was derived, and that the Trustee shall not be held accountable
by reason of mailing any material pursuant to a request made under TIA Section
312(b).

     SECTION 12.02  REPORTS BY TRUSTEE.  Within 60 days after ___________ of
each year commencing with _________, 1998, the Trustee shall transmit by mail to
the Holders, as their names and addresses appear in the Security Register, a
brief report dated as of such _________ in accordance with and to the extent
required under TIA Section 313(a).  The Trustee shall also comply with TIA
Sections 313(b) and 313(c).

     The Company shall promptly notify the Trustee in writing if the Securities
become listed on any stock exchange or automatic quotation system.

     A copy of each Trustee's report, at the time of its mailing to Holders of
Securities, shall be mailed to the Company and filed with the Commission and
each stock exchange, if any, on which the Securities are listed.

     SECTION 12.03  REPORTS BY COMPANY.  The Company shall:

          (a) file with the Trustee, and provide to each Holder, without cost to
     such Holder, within 15 days after the Company is required to file the same
     with the 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 the Commission may from time to time by rules and regulations
     prescribe) which the Company may be required to file with the Commission
     pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the
     Company is not required to file information, documents or reports pursuant
     to either of said Sections, then it shall file with the Trustee and the
     Commission, in accordance with the rules and regulations prescribed from
     time to time by the 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) file with the Trustee and the Commission, in accordance with rules
     and regulations prescribed from time to time by the Commission, such
     additional information, documents and reports with respect to compliance by
     the Company with the conditions and covenants of this Indenture as may be
     required from time to time by such rules and regulations; and

                                       64
<PAGE>

          (c) transmit by mail to all Holders, in the manner and to the extent
     provided in TIA Section 313(c), within 30 days after the filing thereof
     with Trustee, such summaries of any information, documents and reports
     required to be filed by the Company pursuant to paragraphs (a) and (b) of
     this Section as may be required by rules and regulations prescribed from
     time to time by the Commission.  Delivery of such reports, information and
     documents to the Trustee is for informational purposes only and the
     Trustee's receipt of such shall not constitute constructive notice of any
     information contained therein or determinable from information contained
     therein, including the Company's compliance with any of its covenants
     hereunder (as to which the Trustee is entitled to rely exclusively on
     Officers' Certificates).


                                  ARTICLE 13

                                 MISCELLANEOUS

     SECTION 13.01. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any application
or request by the Company to the Trustee to take any action under any provision
of this Indenture, the Company shall furnish to the Trustee, to the extent
required by the TIA or this Indenture, (i) an Officers' Certificate stating that
all conditions precedent, if any, provided for in this Indenture (including any
covenant, compliance with which constitutes a condition precedent) relating to
the proposed action have been complied with and (ii) an Opinion of Counsel
stating that in the opinion of such counsel all such conditions precedent, if
any, have been complied with, except that in the case of any such application or
request as to which the furnishing of such documents is specifically required by
any provision of this Indenture relating to such particular application or
request, no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (i) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (ii) 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;

          (iii)  a statement that, in the opinion of each such individual, 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

          (iv) a statement as to whether or not, in the opinion of each such
     individual, such condition or covenant has been complied with.

     SECTION 13.02. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, 

                                       65
<PAGE>
 
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents.

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

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

     SECTION 13.03. ACTS OF HOLDERS.

          (a) Any request, demand, authorization, direction, notice, consent,
     waiver or other action provided by this Indenture to be given or taken by a
     specified percentage of Holders of Securities of a particular series may be
     embodied in and evidenced by one or more instruments of substantially
     similar tenor signed by such specified percentage of Holders of Securities
     of a particular series in person or by agents duly appointed in writing;
     and, except as herein otherwise expressly provided, such action shall
     become effective when such instrument or instruments are received by the
     Trustee and, where it is hereby expressly required, by the Company. Such
     instrument or instruments (and the action embodied therein and evidenced
     thereby) are herein sometimes referred to as the "ACT" of the Holders
     signing such instrument or instruments. Proof of execution of any such
     instrument or of a writing appointing any such agent shall be sufficient
     for any purpose of this Indenture and (subject to Sections 7.01 and 7.02)
     conclusive in favor of the Trustee and the Company, if made in the manner
     provided in this Section.

          (b) The fact and date of the execution by any Person of any such
     instrument or writing may be proved by the affidavit of a witness of such
     execution or by a certificate of a notary public or other officer
     authorized by law to take acknowledgments of deeds, certifying that the
     individual signing such instrument or writing acknowledged to him the
     execution thereof. Where such execution is by a signer acting in a capacity
     other than his individual capacity, such certificate or affidavit shall
     also constitute sufficient proof of authority. The fact and date of the
     execution of any such instrument or writing, or the authority of the Person
     executing the same, may also be proved in any other manner which the
     Trustee deems sufficient, including the execution of such instrument or
     writing without more.

                                       66
<PAGE>
 
          (c) The ownership, principal amount and serial numbers of Securities
     of any series held by any Person, and the date of holding the same, shall
     be proved by the Security Register.

          (d) If the Company shall solicit from the Holders of Securities of any
     series any request, demand, authorization, direction, notice, consent,
     waiver or other Act, the Company may, at its option, by or pursuant to
     Board Resolution, fix in advance a record date for the determination of
     Holders of Registered Securities entitled to give such request, demand,
     authorization, direction, notice, consent, waiver or other Act, but the
     Company shall have no obligation to do so. Such record date shall be the
     record date specified in or pursuant to such Board Resolution, which shall
     be a date not earlier than the date 30 days prior to the first solicitation
     is completed. If such a record date is fixed, such request, demand,
     authorization, direction, notice, consent, waiver or other Act may be given
     before or after such record date, but only the Holders of record of
     Registered Securities at the close of business on such record date shall be
     deemed to be Holders for the purposes of determining whether Holders of the
     requisite proportion of Outstanding Securities of any series have
     authorized or agreed or consented to such request, demand, authorization,
     direction, notice, consent, waiver or other Act, and for that purpose the
     Outstanding Securities of any series shall be computed as of such record
     date; PROVIDED that no such authorization, agreement or consent by the
     Holders on such record date shall be deemed effective unless it shall
     become effective pursuant to the provisions of this Indenture not later
     than eleven months after the record date.

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

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

     SECTION 13.04. TRUST INDENTURE ACT CONTROLS. If any provision of this
Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the Trust Indenture Act, the
required provision shall control. If any provision of this Indenture modifies or
excludes any provision of the TIA that 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 13.05. NOTICES. Any notice or communication shall be in writing
and delivered in person, or sent by registered or certified mail, by air courier
guaranteeing overnight delivery or by fax (promptly confirmed by telephone) and

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

     Any notice or communication sent to a Registered Holder shall be sent to
the Registered Holder at the Holder's address as it appears on the registration
books of the Registrar and shall be sufficiently given if so sent within the
time prescribed.

     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 hereunder.

     Failure to send a notice or communication to a Holder or any defect in it
shall not effect its sufficiency with respect to other Holders. If a notice or
communication is given in the manner provided above, it is duly given, whether
or not the addressee receives it.

     SECTION 13.06. COMMUNICATION BY HOLDERS WITH OTHER HOLDERS. Holders may
communicate pursuant to TIA Section 312(b) with other Holders with respect to
their rights under this Indenture or the Securities. The Company, the Trustee,
the Registrar and anyone else shall have the protection of TIA Section 312(c).

     SECTION 13.07. RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR. The Trustee
may make reasonable rules for action by or a meeting of Holders. The Registrar
and the Paying Agent may make reasonable rules for their functions.

     SECTION 13.08. LEGAL HOLIDAYS.  A "LEGAL HOLIDAY" is a Saturday, a Sunday
or a day on which banking institutions are not required to be open in the State
of New York. If a payment date is a Legal Holiday, payment shall be made on the
next succeeding day that is not a Legal Holiday, and no interest shall accrue
for the intervening period. If a regular record date is a Legal Holiday, the
record date shall not be affected.

<PAGE>
 
     SECTION 13.09. GOVERNING LAW.  This Indenture and the Securities shall be
governed by, and construed in accordance with, the laws of the State of New York
but without giving effect to applicable principles of conflicts of law to the
extent that the application of the laws of another jurisdiction would be
required thereby.

     SECTION 13.10. NO RECOURSE AGAINST OTHERS.  A director, officer, employee
or stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or this Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By accepting a 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 Securities.

     SECTION 13.11. SUCCESSORS.  All agreements of the Company in this
Indenture and the Securities shall bind its successors. All agreements of the
Trustee in this Indenture shall bind its successors.

     SECTION 13.12. MULTIPLE ORIGINALS.  The parties may sign any number of

which shall be deemed an original, but all such counterparts shall together
constitute but one and the same instrument.

                                 April 8, 1998

Cross Timbers Oil Company
810 Houston Street, Suite 2000
Fort Worth, Texas  76102

     Re:  Registration Statement on Form S-3

Gentlemen:

     This firm has acted as counsel to Cross Timbers Oil Company, 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, for the
registration of the sale from time to time (A) by the Company of up to
$390,000,000 aggregate amount of (i) debt securities of the Company (the "Debt
Securities"), (ii) preferred stock, par value $0.01 per share, of the Company
(the "Preferred Stock"), (iii) common stock, par value $0.01 per share, of the
Company (the "Common Stock") and (iv) warrants of the Company to purchase Debt
Securities, Preferred Stock or Common Stock (the "Warrants") and (B) by certain
selling stockholders of the Company to be named in the Registration Statement of
up to $10,000,000 of Common Stock.

     In connection with this opinion, we have made the following assumptions:
(i) all documents submitted to or reviewed by us, including all amendments and
supplements thereto, are accurate and complete and if not originals are true and
correct copies of the originals; (ii) the signatures on each of such documents
by the parties thereto are genuine; (iii) each individual who signed such
documents had the legal capacity to do so; and (iv) all persons who signed such
documents on behalf of a corporation were duly authorized to do so.  We have
assumed that there are no amendments, modifications or supplements to such
documents other than those amendments, modifications and supplements that are
known to us.

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

     1.  The Company was incorporated, exists and is in good standing under the
laws of the State of Delaware.

     2.  Assuming that any indenture, any Debt Securities and any supplemental
indenture to be entered into in connection with the issuance of such Debt
Securities have been duly authorized, when (i) an indenture and any applicable
supplemental indenture relating to the Debt Securities have been duly executed
and delivered, (ii) the terms of the Debt Securities have been duly established
in accordance with the applicable indenture and the applicable supplemental
indenture relating to 
<PAGE>
 
Cross Timbers Oil Company
April 8, 1998
Page 2

such Debt Securities 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
governmental or regulatory body having jurisdiction over the Company and (iii)
the Debt Securities have been duly executed and authenticated in accordance with
the applicable indenture and the applicable supplemental indenture relating to
such Debt Securities and paid for, duly issued and delivered by the Company in
the manner contemplated in the Registration Statement and any prospectus
supplement relating thereto, then the Debt Securities will constitute valid and
binding obligations of the Company, enforceable in accordance with their terms,
except as (a) the enforceability thereof may be limited by bankruptcy,
insolvency, reorganization, fraudulent transfer, moratorium or other similar
laws now or hereinafter in effect relating to or affecting the enforcement of
creditor's rights generally and (b) the availability of equitable remedies may
be limited by equitable principles of general applicability (regardless of
whether considered in a proceeding at law or in equity).
 
     3.  When all necessary corporate action on the part of the Company has been
taken  to authorize the issuance and sale of the shares of the class of
currently outstanding Common Stock proposed to be sold by the Company, or upon
designation of the relative rights, preferences and limitations of any other
class or series of Common Stock by the Board of Directors of the Company and the
proper filing with the Secretary of State of the State of Delaware of a
Statement of Designations, Preferences and Rights relating to such class or
series of Common Stock, all necessary corporate action on the part of the
Company will have been taken to authorize the issuance and sale of such class or
series of Common Stock proposed to be sold by the Company, and when such shares
of Common Stock are paid for, issued and delivered in accordance with the
applicable underwriting or other agreement, then such shares of Common Stock
(including any shares of Common Stock issuable upon (i) conversion or exchange
of any Debt Securities that are convertible or exchangeable into Common Stock,
(ii) conversion or exchange of any shares of Preferred Stock that are
convertible or exchangeable into Common Stock or (iii) exercise of any Warrants
for Common Stock) will be validly issued, fully paid and non-assessable.

     4.  Upon designation of the relative rights, preferences and limitations of
any class or series of Preferred Stock by the Board of Directors of the Company
and the proper filing with the Secretary of State of the State of Delaware of a
Statement of Designations, Preferences and Rights relating to such class or
series of Preferred Stock, all necessary corporate action on the part of the
Company will have been taken to authorize the issuance and sale of such class or
series of Preferred Stock proposed to be sold by the Company, and when such
shares of Preferred Stock are paid for, issued and delivered in accordance with
