the accompanying Letter of Transmittal relating to the Exchange Offer (the
"Letter of Transmittal"), to exchange $1,000 principal amount of its 7 7/8%
Series B Senior Notes due 2004 ("New Notes due 2004") and $1,000 principal
amount of its 8 1/2% Series B Senior Notes due 2012 ("New Notes due 2012" and,
together with its New Notes due 2004, the "New Notes") for each $1,000 principal
amount of its 7 7/8% Series A Senior Notes due 2004 ("Old Notes due 2004") and
$1,000 principal amount of its 8 1/2% Series A Senior Notes due 2012 ("Old Notes
due 2012" and, together with its Old Notes due 2004, the "Old Notes"),
respectively. The New Notes will be registered under the Securities Act of 1933,
as amended (the "Securities Act"), pursuant to a Registration Statement of which
this Prospectus is a part. An aggregate of $150,000,000 principal amount of Old
Notes due 2004, and an aggregate of $150,000,000 principal amount of Old Notes
due 2012 were outstanding as of        , 1997. The New Notes will be obligations
of the Company entitled to the benefits of the respective Indentures under which
they will be issued. The form and terms of the New Notes are identical in all
material respects to the form and terms of the Old Notes except that the New
Notes have been registered under the Securities Act. Any Old Notes not tendered
and accepted in the Exchange Offer will remain outstanding and will be entitled
to all the rights and preferences and will be subject to the limitations
applicable thereto under the Indentures. Following consummation of the Exchange
Offer, the holders of the Old Notes will continue to be subject to the existing
restrictions upon transfer thereof and the Company will have no further
obligation to such holders to provide for the registration under the Securities
Act of the Old Notes held by them. Following the completion of the Exchange
Offer, none of the New Notes will be entitled to the contingent increase in
interest rate provided pursuant to the Old Notes. The New Notes and the Old
Notes are collectively referred to herein as the "Senior Notes."
 
     The Exchange Offer is being made pursuant to the terms of the registration
rights agreement (the "Registration Rights Agreement") entered into between the
Company and its subsidiaries guaranteeing the Senior Notes (the "Subsidiary
Guarantors") and Donaldson, Lufkin & Jenrette Securities Corporation, Bear,
Stearns & Co. Inc., Lehman Brothers Inc. and J.P. Morgan Securities Inc. (the
"Initial Purchasers") pursuant to the terms of the Purchase Agreement dated
March 12, 1997 between the Company and the Subsidiary Guarantors and the Initial
Purchasers. See "The Exchange Offer -- Purpose and Effect of the Exchange
Offer."
 
     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes the New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and otherwise
transferred by any holder thereof (other than broker-dealers, as set forth
below, and any such holder that is an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such New Notes are acquired in the ordinary course of such holder's
business and that such holder has no arrangement or understanding with any
person to participate in the distribution of such New Notes. Any holder who
tenders in the Exchange Offer with the intention to participate, or for the
purpose of participating, in a distribution of the Senior Notes or who is an
affiliate of the Company may not rely upon such interpretations by the staff of
the Commission and, in the absence of an exemption therefrom, must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any secondary resale transaction. Holders of Old Notes wishing
to accept the Exchange offer must represent to the Company in the Letter of
Transmittal that such conditions have been met.

     Each broker-dealer (other than an affiliate of the Company) that receives
New Notes for its own account pursuant to the Exchange Offer must acknowledge
that it will deliver a prospectus in connection with any resale of such Senior
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. This Prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes where such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities. The Company has agreed
that, for a period of one year, if required, after the date of this Prospectus,
it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution." Any broker-dealer
who is an affiliate of the Company may not rely on such no-action letters and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction.

                                  THE COMPANY
 
     Chesapeake Energy Corporation is an independent energy company which
utilizes advanced drilling and completion technologies to explore for and
produce oil and natural gas. The Company is currently the third most active
driller of new wells in the United States.
 
     From its inception in 1989 through December 31, 1996, Chesapeake drilled a
total of 640 gross (233 net) wells, of which 603 gross (220 net) wells were
commercially productive. As a result of its successful drilling efforts, the
Company has experienced significant growth in its proved reserves, production,
revenue, and assets. From its first full fiscal year of operation ended June 30,
1990 to the twelve months ended December 31, 1996, the Company's estimated
proved reserves increased to 494 Bcfe from 11 Bcfe, annual production increased
to 70 Bcfe from 0.2 Bcfe, total revenue increased to $216.6 million from $0.6
million, and total assets increased to $861 million from $8 million.
 
     At December 31, 1996, the Company's estimated proved reserves consisted of
20 MMBbl of oil and 374 Bcf of gas, a total of 494 Bcfe. During the eighteen
months ended December 31, 1996, the Company's proved reserves increased from 242
Bcfe to 494 Bcfe, an increase of 252 Bcfe, or a greater than three-fold
replacement of its 97 Bcfe of production during that period. At December 31,
1996 the present value of estimated future net revenue attributable to
Chesapeake's estimated proved reserves before income taxes (utilizing a 10%
discount rate) was $963 million, based on average prices at December 31, 1996 of
$24.55 per Bbl and $3.55 per Mcf. At December 31, 1996 the Company had an
inventory of approximately 1,075 undrilled locations (including 175 proved
undeveloped locations), providing the Company with an estimated five-year
inventory of drilling opportunities.
 
     The Company operates approximately 80% of the wells in which it owns an
interest. Of the 640 wells drilled by the Company through December 31, 1996, 330
were horizontal wells, reflecting the Company's emphasis on utilizing horizontal
drilling technology.
 
                               BUSINESS STRATEGY
 
     Since its inception, Chesapeake's business strategy has been growth through
the drillbit. Using this strategy, the Company has expanded its reserves and
production through the acquisition and subsequent development of large blocks of
acreage. The Company has focused its activities in areas where reservoirs such
as fractured carbonates offer low geological risk, large reserve potential, and
the opportunity to earn attractive economic returns through the application of
advanced drilling and completion technologies.
 
     The Company's three primary operating areas are: (i) the Giddings Field of
southern Texas, (ii) the Louisiana Austin Chalk Trend (the "Louisiana Trend") in
eastern Texas and central Louisiana and (iii) the Knox, Sholem Alechem, and
Golden Trend fields of southern Oklahoma. In addition, the Company continues to
search for other areas in the United States and Canada where its geological and
engineering expertise provides the Company with competitive advantages. The
additional project areas identified to date include the Williston Basin in
eastern Montana and western North Dakota, the Arkoma Basin in southeastern
Oklahoma, the Lovington area in eastern New Mexico, the Deep Wilcox Trend in
Wharton County, Texas, and the Edwards Trend along the Upper Texas Gulf Coast.
Additionally, the Company has recently initiated a
                                        3

leasehold acquisition program in western Canada and plans to open a district
office in Calgary, Alberta in the near future.
 
     The Company's operating areas are typically characterized by fractured
carbonate reservoirs that are known to contain oil and gas and generally cover a
large geographic area. In the past, development of these reservoirs has been
limited by both economic and technological factors. Recent advances in drilling
and completion technologies, and the resulting higher reserve recoveries and
lowered exploration costs, provide the Company with the opportunity to develop
large new reserves of oil and natural gas and to generate attractive economic
returns.
 
     On March 17, 1997, the Company consummated an offering of the Old Notes
(the "Offering"), resulting in approximately $292.4 million of net proceeds to
the Company. The proceeds of the Offering will allow the Company to expand
further its existing exploration and development activities and to pursue new
exploration projects. Management believes that the Company's growth through the
drillbit business strategy, distinct competitive advantages and its successful
exploration track record provide the basis for continued growth in reserves and
production. Consistent with its previous statements, management seeks to achieve
an investment grade senior debt rating during the next few years.
 
                             COMPETITIVE ADVANTAGES
 
     Management believes five competitive advantages are responsible for
Chesapeake's rapid growth and distinguish the Company from other independent
energy companies.
 
     Growth Through the Drillbit. Employing its strategy of growth through the
drillbit, the Company has substantially increased its reserves and production.
By focusing drilling efforts on reservoirs that respond favorably to the
application of advanced drilling and completion technologies, management
believes the Company can continue to increase its reserves and production and
generate attractive returns by integrating the Company's technical expertise
with its large inventory of undeveloped leasehold.
 
     Dominant Leasehold Positions. Through aggressive acreage acquisition in its
existing and new project areas, the Company seeks to establish a dominant
leasehold position in each of its project areas. Such a dominant position allows
the Company to maximize its economic returns while limiting drilling
opportunities available to its competitors. Consistent with this strategy, the
Company has assembled a significant leasehold acreage inventory which included
approximately 1,075 proved and unproved drilling locations at December 31, 1996.
 
     Technological Leadership. The Company has developed significant expertise
in the rapidly evolving technologies of horizontal drilling, 3-D seismic
evaluation, and deep fracture stimulation. The Company believes its expertise in
employing these technologies is the most important factor in its growth during
the past several years. In particular, the Company has developed considerable
horizontal drilling and completion expertise, especially in wells which target
deep fractured carbonates. Over the last several years, deeper, more complex
horizontal wells have become technically and economically feasible and the cost
of drilling these wells has decreased. As a result, the Company believes there
has been a substantial increase in the number of areas which are economically
attractive for horizontal drilling.
 
     Superior Operating Margin. Management believes the Company's operating cost
structure is among the lowest of all publicly traded independent energy
producers. For the twelve months ended December 31, 1996, the Company's per unit
operating costs (consisting of general and administrative expense, lease
operating expense, production taxes, and depreciation, depletion and
amortization of oil and gas properties) were $1.17 per Mcfe produced, resulting
in an operating margin of $1.04 per Mcfe. Management believes the key to
creating value in the independent energy industry is the ability to generate
high levels of cash flow per Mcfe that can be successfully reinvested in a
technologically-driven exploration program.
 
     Management's Substantial Equity Ownership. At February 28, 1997, the
Company's management and directors beneficially owned (including outstanding
vested options) an aggregate of approximately 42% of the Company's outstanding
shares of Common Stock. Management believes this substantial equity ownership
                                        4

provides a strong alignment of management's and investors' interests and creates
an entrepreneurial culture within the Company.
 
                            PRIMARY OPERATING AREAS
 
     The Company's activities are concentrated in three primary operating areas:
(i) the Navasota River and Independence areas of the downdip Giddings Field in
southern Texas, (ii) the South Brookeland, Leesville, Masters Creek, St. Landry,
Baton Rouge and Livingston areas of the Louisiana Trend, and (iii) the Knox,
Sholem Alechem, and Golden Trend fields of southern Oklahoma.
 
GIDDINGS FIELD
 
     Chesapeake's second largest concentration of proved reserves and its
highest concentration of present value are located in the Giddings Field, which
is one of the most active oil and natural gas fields in the U.S. The primary
producing formation in Giddings is the Austin Chalk formation, a fractured
carbonate reservoir found at depths ranging from 7,000 feet to 17,000 feet along
a 15,000 square mile trend in southeastern Texas and central Louisiana.
Chesapeake has concentrated its drilling efforts in the gas-prone downdip
portion of the Giddings Field, where the Austin Chalk is located at depths below
11,000 feet. The Company believes the downdip Giddings area is one of the
largest discoveries of onshore gas in the U.S. in recent years.
 
     The Company believes that its success in the downdip Giddings Field is
attributable to four principal factors: (i) limited reservoir drainage from
previously drilled vertical wells; (ii) the Company's aggressive leasehold
acquisition program, which has permitted the creation of larger spacing units,
thus reducing competition for reserves from offsetting wells; (iii) continued
technological advances in horizontal drilling, which have significantly lowered
development costs, expanded the field's boundaries into deeper areas, and
increased per well productivity through the ability to drill within a more
precisely defined target zone; and (iv) the geological setting of the downdip
Austin Chalk, which is characterized by greater reservoir pressure and more
intensive fracturing than in the updip area of the Giddings Field. As a result
of these factors, the Company's downdip wells have, on average, produced greater
reserves per well while also exhibiting lower decline rates than average wells
drilled in areas of updip Austin Chalk production.
 
     Navasota River. In February 1994, Chesapeake drilled its first well in the
Navasota River leasehold block, located in Brazos and Grimes Counties, Texas. To
date, the Company has successfully completed 90 of 91 Navasota River wells and
is drilling nine additional wells.
 
     Independence. Chesapeake's Independence block is located in Grimes and
Washington Counties to the south and southwest (and further downdip) from the
Navasota River area. To date, the Company has successfully completed 29 of 32
Independence wells and is drilling two additional wells.
 
LOUISIANA AUSTIN CHALK TREND
 
     The Louisiana Trend is the newest of the Company's primary operating areas
and will be central to the Company's exploration and development activities over
the next several years. As part of the Company's ongoing development of new
exploration areas, the Company began intensive investigation of the geological
characteristics of the Louisiana Austin Chalk in 1995. After evaluating the
large number of vertical wells that were drilled during the 1970's and 1980's
through the Austin Chalk to explore for deeper horizons, the Company concluded
that the Austin Chalk in the Louisiana Trend offered geological characteristics
similar to the Austin Chalk in the downdip Giddings Field. To capitalize on this
opportunity, the Company has acquired approximately 1,200,000 acres of leasehold
in the Louisiana Trend and continues to expand its leasehold.
 
     The Company commenced its first Louisiana Trend well in November 1995 and,
to date, has commenced drilling operations on 27 Company-operated wells. Of
these 27 wells, ten are producing, four are waiting on completion, three have
been abandoned and ten have commenced drilling operations. Additionally, based
on the most recent information available to the Company, management believes its
competitors in the Louisiana Trend (Union Pacific Resources Corporation, Sonat
Exploration Company, Occidental Petroleum Corporation, and Belco Oil & Gas
Corp.) have drilled 12 successful wells out of 14 attempts in the Louisiana
Trend
                                        5
<PAGE>   10
 
and are currently drilling nine additional wells. Total activity to date in the
Louisiana Trend has resulted in 26 successful wells out of 31 tests, or an 84%
drilling success rate.
 
SOUTHERN OKLAHOMA
 
     Chesapeake's largest concentration of proved reserves is located in
southern Oklahoma and is comprised of the Knox, Golden Trend and Sholem Alechem
fields. To date, Chesapeake has successfully completed 177 of 180 wells drilled
in the Knox and Golden Trend fields and is drilling six additional wells. In the
Sholem Alechem portion of southern Oklahoma's Sho-Vel-Tum Field, the Company has
successfully completed 27 of 27 horizontal wells in the Sycamore formation and
has successfully completed its first McLish well, the industry's first
horizontal test of this deeper fractured carbonate reservoir. Chesapeake is
currently drilling three additional wells in this area.
 
OTHER OPERATING AREAS
 
     Williston Basin. During fiscal 1996, Chesapeake began acquiring leasehold
in the Williston Basin, located in eastern Montana and western North Dakota, and
as of December 31, 1996 owned approximately 650,000 gross (500,000 net) acres.
The primary focus of Chesapeake's exploration efforts in the southern portion of
this basin is a horizontal drilling target, the Red River "B" formation in
Bowman and Slope Counties, North Dakota and in Fallon County, Montana. Although
other Red River "B" horizontal wells have been successfully drilled to date by
other companies in this area, Chesapeake's first Red River "B" well was
unsuccessful. Further drilling in this area is planned by the Company later in
1997.
 
     In the northern portion of the Williston Basin, the Company is focusing its
exploratory efforts on drilling vertical wells to the Red River "C" and "D"
formations using 3-D seismic. The Company's first three such wells were
successful and accelerated drilling and 3-D seismic activity are planned for
1997.
 
     Lovington. In late 1994, Chesapeake initiated activity in the Lovington
portion of the Permian Basin of Lea County, New Mexico. In this project, the
Company is utilizing 3-D seismic technology to evaluate the Strawn formation in
which management believes significant prospects have been overlooked because of
inconclusive results provided by traditional 2-D seismic technology. The Company
has been successful with its first five exploratory wells and is currently
drilling two additional exploratory wells. The Company has identified
approximately 50 prospects in the Lovington area and is planning to increase its
drilling and seismic activity in this area in 1997.
 
     Upper Texas Gulf Coast. In this new project area, Chesapeake is pursuing
two distinct geological prospects. The first, in Wharton County, targets the
deep (19,000 feet) Wilcox sands that have been penetrated by the Zeidman Trustee
#1, an apparent significant Wilcox discovery recently drilled by Coastal Oil &
Gas Corporation and Seagull Energy Corporation. This well is the deepest well
ever drilled in Wharton County and may serve as a catalyst for other deep Wilcox
exploration tests in the area. Chesapeake has recently acquired 25,000 net acres
of leasehold in the area near the Zeidman Trustee well and believes it is now
one of the largest leasehold owners in the Zeidman Trustee well area.
 
     In addition, Chesapeake has recently drilled two successful producers in
the Edwards formation, a fractured carbonate formation that is deeper than the
Austin Chalk. The Company has initiated a three-county leasehold acquisition and
seismic program.
 
     Canada. In the Western Sedimentary Basin of Alberta and British Columbia,
Chesapeake has recently initiated several leasehold acquisition projects focused
on reservoirs that the Company believes may respond favorably to the application
of horizontal drilling technology. The Company plans to initiate drilling
activities in Canada in late 1997 or early 1998.

(a) If such estimate had been calculated based on average prices realized by the
    Company at June 30, 1996 the total present value of estimated future net
    revenue before income taxes would have been approximately $638 million.
 
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures, including many factors beyond the control of the
producer. See "Risk Factors -- Uncertainty of Estimates of Oil and Gas Reserves"
and "-- Commodity Price Fluctuations."

    expense and depreciation, depletion and amortization.
 
(c) EBITDA represents net income of the Company and its subsidiaries from
    continuing operations before interest, taxes, depreciation, depletion,
    amortization, extraordinary items, certain other non-cash charges and, with
    respect to fiscal 1993, the provision for legal and other settlements.
    EBITDA should not be considered in isolation or as a substitute for net
    income, cash flows from continuing operations or other consolidated income
    or cash flow data prepared in accordance with generally accepted accounting
    principles or as a measure of the Company's profitability or liquidity.
 
(d) For purposes of determining the ratio of earnings to fixed charges, earnings
    are defined as income (loss) of the Company and its subsidiaries from
    continuing operations before income taxes, extraordinary items and fixed
    charges. Fixed charges consist of interest (whether expensed or
    capitalized), and amortization of debt expenses and discount or premium
    relating to any indebtedness. Earnings were insufficient to cover fixed
    charges in fiscal 1993 by $464,000.
 
(e) The pro forma data, which exclude amounts for Chesapeake Energy Marketing
    Inc. ("CEM"), which will not be a Subsidiary Guarantor, have been prepared
    on the basis of the following assumptions: (i) the Offering was consummated
    at the beginning of each period, (ii) $300 million principal amount of
    Senior Notes was outstanding during each period, (iii) interest as reported
    for each period was reduced by the amount of interest recorded for
    indebtedness which was repaid prior to the end of such period, and (iv) the
    outstanding balance under the Term Credit Facility was repaid at the
    beginning of each period.
 
(f) Gives effect to the application of net proceeds of approximately $292.4
    million from the sale of the Old Notes on March 17, 1997.

                                  RISK FACTORS
 
     In addition to the other information set forth elsewhere or incorporated by
reference in this Prospectus, the following factors relating to the Company and
the Exchange Offer should be considered when evaluating an investment in the New
Notes offered hereby.
 
CONCENTRATION IN LOUISIANA TREND
 
     In addition to the development of its existing proved reserves, the Company
expects that its inventory of unproved drilling locations will be the primary
source of new reserves, production and cash flow over the next few years. The
Louisiana Trend, in particular, is a key element of the existing inventory. The
Company had invested approximately $114 million through December 31, 1996 to
acquire approximately 1,200,000 acres of leasehold in the Louisiana Trend which
is largely undeveloped and unproven. Moreover, approximately 40% of the
Company's fiscal year 1997 drilling budget is associated with drilling and
acreage acquisition activity in the Louisiana Trend. There can be no assurance
that the Louisiana Trend will yield substantial economic returns. Failure of the
Louisiana Trend to yield significant quantities of economically attractive
reserves and production could have a material adverse impact on the Company's
future financial condition and results of operations and could result in a
write-off of a significant portion of its investment in the Louisiana Trend.
 
NEED TO REPLACE RESERVES; SUBSTANTIAL CAPITAL REQUIREMENTS
 
     As is customary in the oil and gas exploration and production industry, the
Company's future success depends upon its ability to find, develop or acquire
additional oil and gas reserves that are economically recoverable. Unless the
Company successfully replaces the reserves that it produces through successful
development, exploration or acquisition, the Company's proved reserves will
decline. Further, approximately 56% of the Company's estimated proved reserves
at December 31, 1996 were located in the Austin Chalk formation, where wells are
characterized by relatively rapid decline rates. Additionally, approximately 55%
of the Company's total estimated proved reserves at December 31, 1996 were
undeveloped. Recovery of such reserves will require significant capital
expenditures and successful drilling operations. There can be no assurance that
the Company will continue to be successful in its effort to develop or replace
its proved reserves.
 
     The Company has made and intends to make substantial capital expenditures
in connection with the exploration and production of its oil and gas properties.
Historically, the Company has funded its capital expenditures through a
combination of internally generated funds, equity and long-term debt financing,
and short-term financing arrangements. The Company anticipates that the net
proceeds from the Offering, together with its cash flow from operations will be
sufficient to meet estimated capital expenditures through fiscal 1999, including
increases in capital expenditures being presently evaluated. Future cash flows
are subject to a number of variables, such as the level of production from
existing wells, prices of oil and gas and the Company's success in locating and
producing new reserves. If revenue were to decrease as a result of lower oil and
gas prices, decreased production or otherwise, and the Company had no available
credit facility, the Company could have a reduced ability to replace its
reserves or to maintain production at current levels, potentially resulting in a
decrease in production and revenue over time. If the Company's cash flow from
operations are not sufficient to satisfy its capital expenditure budget, there
can be no assurance that additional debt or equity financing will be available
to meet these requirements.
 
COMMODITY PRICE FLUCTUATIONS
 
     The Company's revenue, profitability and future rate of growth are
substantially dependent upon prevailing prices for oil, gas and natural gas
liquids, which are dependent upon numerous factors such as weather, economic,
political and regulatory developments and competition from other sources of
energy. The volatile nature of the energy markets makes it particularly
difficult to estimate future prices of oil, gas and natural gas liquids. Prices
of oil, gas and natural gas liquids are subject to wide fluctuations in response
to relatively minor changes in circumstances, and there can be no assurance that
future prolonged decreases in such prices will not occur. All of these factors
are beyond the control of the Company. Any significant decline
 
                                       15
<PAGE>   20
 
in oil and gas prices could have a material adverse effect on the Company's
operations, financial condition and level of expenditures for the development of
its oil and gas reserves, and may result in violations of certain covenants
contained in the Company's credit agreements.
 
UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES
 
     There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves, including many factors beyond the control of the
Company. The Company obtained an estimate of its proved oil and gas reserves and
the estimated future net revenue therefrom based upon a report prepared as of
June 30, 1996 by Williamson and the Company's petroleum engineers and as of
December 31, 1996 prepared by the Company's petroleum engineers. The portion of
the reserves evaluated solely by the Company's petroleum engineers as of June
30, 1996 constituted 0.6% of the Company's total proved reserves at that date.
These estimates rely upon various assumptions, including assumptions required by
the Commission as to constant oil and gas prices, drilling and operating
expenses, capital expenditures, taxes and availability of funds. The process of
estimating oil and gas reserves is complex, requiring significant decisions and
assumptions in the evaluation of available geological, geophysical, engineering
and economic data for each reservoir. As a result such estimates are subject to
great uncertainty, and this is particularly true as to proved undeveloped
reserves, which are inherently less certain than proved developed reserves and
which comprise a significant portion of the Company's proved reserves. Actual
future production, revenue, taxes, development expenditures, operating expenses
and quantities of recoverable oil and gas reserves may vary substantially from
those estimated by the Company. Any significant variance in these assumptions
could materially affect the estimated quantity and value of reserves set forth
in this Prospectus. In addition, the Company's reserves may be subject to
downward or upward revision, based upon production history, results of future
exploration and development, prevailing oil and gas prices and other factors,
many of which are beyond the Company's control.
 
DRILLING AND OPERATING RISKS
 
     Oil and gas drilling activities are subject to numerous risks, many of
which are beyond the Company's control. The Company's operations may be
curtailed, delayed or canceled as a result of title problems, weather
conditions, compliance with governmental requirements, mechanical difficulties
and shortages or delays in the delivery of equipment. In addition, the Company's
properties may be susceptible to hydrocarbon drainage from production by other
operators on adjacent properties. Industry operating risks include the risk of
fire, explosions, blow-outs, pipe failure, abnormally pressured formations and
environmental hazards such as oil spills, gas leaks, ruptures or discharges of
toxic gases, the occurrence of any of which could result in substantial losses
to the Company due to injury or loss of life, severe damage to or destruction of
property, natural resources and equipment, pollution or other environmental
damage, clean-up responsibilities, regulatory investigation and penalties and
suspension of operations.
 
     The Company has been among the most active drillers of horizontal wells and
expects to drill a significant number of deep horizontal wells in the future.
The Company's horizontal drilling activities involve greater risk of mechanical
problems than conventional vertical drilling operations. In some cases, the
locations will require wells to be drilled to greater depths, which may involve
more complex drilling than wells drilled to date. These wells may be
significantly more expensive to drill than those drilled to date.
 
     In accordance with customary industry practice, the Company maintains
insurance against some, but not all, of the risks described above. There can be
no assurance that any insurance will be adequate to cover losses or liabilities.
The Company cannot predict the continued availability of insurance, or its
availability at premium levels that justify its purchase.
 
RESTRICTIONS IMPOSED BY LENDERS; RESTRICTIONS IMPOSED BY LENDERS UNDER CERTAIN
CIRCUMSTANCES
 
     The instruments governing the indebtedness of the Company and its
Restricted Subsidiaries impose significant operating and financial restrictions
on the Company. The terms of the Indentures governing the Senior Notes and the
Indentures governing the Existing Notes (the "Existing Notes Indentures")
affect, and in many respects significantly limit or prohibit, among other
things, the ability of the Company to incur
 
                                       16
<PAGE>   21
 
additional indebtedness, pay dividends, repay indebtedness prior to its stated
maturity, sell assets or engage in mergers or acquisitions. See "Description of
Other Indebtedness" and "Description of Senior Notes -- Certain Covenants."
These restrictions could also limit the ability of the Company to effect future
financings, make needed capital expenditures, withstand a future downturn in the
Company's business or the economy in general, or otherwise conduct necessary
corporate activities. A failure by the Company to comply with these restrictions
could lead to a default under the terms of such indebtedness and the Senior
Notes. In the event of default, the holders of such indebtedness could elect to
declare all of the funds borrowed pursuant thereto due and payable together with
accrued and unpaid interest. In such event, there can be no assurance that the
Company would be able to make such payments or borrow sufficient funds from
alternative sources to make any such payment. Even if additional financing could
be obtained, there can be no assurance that it would be on terms that are
favorable or acceptable to the Company.
 
     The Company must offer to purchase the Existing Notes upon the occurrence
of certain events. In the event of a Change of Control, the Company must offer
to purchase all Existing Notes then outstanding at a purchase price equal to
101% of the principal amount thereof, plus accrued and unpaid interest to the
date of purchase. In the event of certain asset dispositions, the Company will
be required under certain circumstances to use the Excess Proceeds (as defined)
to offer to purchase the Existing Notes at 100% of the principal amount thereof,
plus accrued and unpaid interest to the date of purchase (a "Net Proceeds
Offer"). There are no similar covenants in the Indentures. In the event the
Company is required to make a Net Proceeds Offer or an offer to purchase the
Existing Notes upon a Change of Control, there is no requirement that the
Company make a similar offer with respect to the Senior Notes. Under such
circumstances, the Senior Notes may be considered to be effectively subordinated
in right of payment to the Existing Notes. See "Description of Senior
Notes -- Certain Covenants" and "Description of Other Indebtedness."
 
PATENT LITIGATION
 
     In October 1996, Union Pacific Resources Company ("UPRC") filed suit
against the Company in the United States District Court for the Northern
District of Texas alleging (a) infringement of UPRC's claimed patent (the "UPRC
Patent") for an invention involving a method of maintaining a bore hole in a
stratigraphic zone during drilling, and (b) tortious interference with contracts
between UPRC and a third party vendor regarding the confidentiality of
proprietary information of UPRC. UPRC is seeking injunctive relief, damages of
an unspecified amount, including actual, enhanced, consequential and punitive
damages, interest, costs and attorney's fees. The Company believes that it has
meritorious defenses to UPRC's allegations, including, without limitation, the
Company's belief that the UPRC Patent is invalid. Although the Company will
vigorously defend the lawsuit, no assurance can be given as to the outcome of
the matter or the ultimate impact on the Company of any damages (which could be
substantial) that may be awarded to UPRC because litigation is inherently
uncertain.
 
GOVERNMENTAL REGULATION
 
     Oil and gas operations are subject to various federal, state and local
governmental regulations which may be changed from time to time in response to
economic or political conditions. From time to time, regulatory agencies have
imposed price controls and limitations on production in order to conserve
supplies of oil and gas. In addition, the production, handling, storage,
transportation and disposal of oil and gas, by-products thereof and other
substances and materials produced or used in connection with oil and gas
operations are subject to regulation under federal, state and local laws and
regulations primarily relating to protection of human health and the
environment. To date, expenditures related to complying with these laws and for
remediation of existing environmental contamination have not been significant in
relation to the results of operations of the Company. There can be no assurance
that the trend of more expansive and stricter environmental legislation and
regulations will not continue.
 
COMPETITION
 
     The Company operates in a highly competitive environment. The Company
competes with major and independent oil and gas companies for the acquisition of
desirable oil and gas properties, as well as for the
 
                                       17
<PAGE>   22
 
equipment and labor required to develop and operate such properties. Many of
these competitors have financial and other resources substantially greater than
those of the Company.
 
RELIANCE ON KEY PERSONNEL; CONFLICTS OF INTEREST
 
     The Company is dependent upon its Chief Executive Officer, Aubrey K.
McClendon, and its Chief Operating Officer, Tom L. Ward. The unexpected loss of
the services of either of these executive officers could have a detrimental
effect on the Company. The Company maintains $20 million key man life insurance
policies on the life of each of Messrs. McClendon and Ward.
 
     Messrs. McClendon and Ward, together with another executive officer of the
Company, have rights to, and do, participate in wells drilled by the Company.
Such participation may create interests which conflict with those of the
Company.
 
CONTROL BY CERTAIN STOCKHOLDERS
 
     At February 28, 1997, Aubrey K. McClendon, Tom L. Ward, the Aubrey K.
McClendon Children's Trust and the Tom L. Ward Children's Trust beneficially
owned an aggregate of 24,456,768 shares (including outstanding vested options)
representing approximately 34% of the Company's outstanding Common Stock, and
members of the Company's Board of Directors and senior management, including
Messrs. McClendon and Ward and their respective children's trusts, beneficially
owned an aggregate of 28,233,074 shares (including outstanding vested options),
which represented approximately 42% of the Company's outstanding Common Stock.
As a result, Messrs. McClendon and Ward, together with other officers and
directors of the Company, are in a position to effectively control the Company
through their ability to significantly influence matters requiring the vote or
consent of the Company's stockholders.
 
ABSENCE OF A PUBLIC MARKET FOR THE SENIOR NOTES
 
     The Senior Notes are a new issue of securities with no established trading
market, and there can be no assurance as to the liquidity of any markets that
may develop for the Senior Notes, the ability of the holders of Senior Notes to
sell their Senior Notes or the price at which holders would be able to sell
their Senior Notes. Future trading prices of the Senior Notes will depend on
many factors, including, among others, prevailing interest rates, the Company's
operating results and the market for similar securities. The Company does not
intend to apply for listing of the Senior Notes on any national securities
exchange or the Nasdaq National Market. The investment banking firms which were
the Initial Purchasers have informed the Company that they currently intend to
make a market for the Senior Notes. However, they are not so obligated, and any
such market making may be discontinued at any time without notice. See "Plan of
Distribution." Accordingly, no assurance can be given that an active public or
other market will develop for the Senior Notes or as to the liquidity of or the
trading market for the Senior Notes.
 
CONSEQUENCES OF THE EXCHANGE OFFER ON NON-TENDERING HOLDERS OF THE OLD NOTES
 
     In the event the Exchange Offer is consummated, the Company will not be
required to register any Old Notes not tendered and accepted in the Exchange
Offer. In such event, holders of Old Notes seeking liquidity in their investment
would have to rely on exemptions to the registration requirements under the
securities laws, including the Securities Act. Following the Exchange Offer,
none of the Senior Notes will be entitled to the contingent increase in interest
rate provided for (in the event of a failure to consummate the Exchange Offer in
accordance with the terms of the Registration Rights Agreement) pursuant to the
Old Notes.

                                  THE COMPANY
 
     Chesapeake Energy Corporation is an independent energy company which
utilizes advanced drilling and completion technologies to explore for and
produce oil and natural gas. The Company's executive offices are located at 6100
North Western Avenue, Oklahoma City, Oklahoma 73118 and its telephone number is
(405) 848-8000.
 
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     The Old Notes were sold by Chesapeake on March 17, 1997 to Donaldson,
Lufkin & Jenrette Securities Corporation, Bear, Stearns & Co. Inc., Lehman
Brothers Inc. and J.P. Morgan Securities Inc. (together, the "Initial
Purchasers") in reliance on Section 4(2) of the Securities Act. The Initial
Purchasers offered and sold the Old Notes only (i) to "qualified institutional
buyers" (as defined in Rule 144A) in compliance with Rule 144A, (ii) to a
limited number of other institutional "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) that, prior to their
purchase of Old Notes, delivered to the Initial Purchasers a letter containing
certain representations and agreements, and (iii) outside the United States to
persons other than U.S. Persons, which term includes dealers or other
professional fiduciaries in the United States acting on a discretionary basis
for foreign beneficial owners (other than an estate or trust), in reliance upon
Regulation S under the Securities Act.
 
     In connection with the sale of the Old Notes, the Company and the Initial
Purchasers entered into a Registration Rights Agreement dated as of March 12,
1997 (the "Registration Rights Agreement"), which requires the Company (i) to
cause the Old Notes to be registered under the Securities Act, or (ii) to file
with the Commission a registration statement under the Securities Act with
respect to an issue of new notes of the Company identical in all material
respects to the Old Notes and use its best efforts to cause such registration
statement to become effective under the Securities Act and, upon the
effectiveness of that registration statement, to offer to the holders of the Old
Notes the opportunity to exchange their Old Notes for a like principal amount of
New Notes, which will be issued without a restrictive legend and which may be
reoffered and resold by the holder without restrictions or limitations under the
Securities Act. A copy of the Registration Rights Agreement has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
Exchange Offer is being made pursuant to the Registration Rights Agreement to
satisfy the Company's obligations thereunder with regard to the Senior Notes.
The term "Holder" with respect to the Exchange Offer means any person in whose
name Old Notes are registered on the trustee's books or any other person who has
obtained a properly completed bond power from the registered holder, or any
person whose Old Notes are held of record by The Depository Trust Company
("DTC") who desires to deliver such Old Notes by book-entry transfer at DTC.
 
     The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the New
Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be
offered for sale, resold or otherwise transferred by any holder without
compliance with the registration and prospectus delivery provisions of the
Securities Act. Based on interpretations by the staff
 
                                       19
<PAGE>   24
 
of the Commission set forth in no-action letters issued to third parties, the
Company believes the New Notes issued pursuant to the Exchange Offer in exchange
for Old Notes may be offered for resale, resold and otherwise transferred by any
holder thereof (other than broker-dealers, as set forth below, and any such
holder that is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such Senior
Notes are acquired in the ordinary course of such holder's business and that
such holder has no arrangement or understanding with any person to participate
in the distribution of such New Notes. Any holder who tenders in the Exchange
Offer with the intention to participate, or for the purpose of participating, in
a distribution of the New Notes or who is an affiliate of the Company may not
rely upon such interpretations by the staff of the Commission and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
secondary resale transaction. Failure to comply with such requirements in such
instance may result in such holder incurring liabilities under the Securities
Act for which the holder is not indemnified by the Company. Each broker-dealer
(other than an affiliate of the Company) that receives Senior Notes for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. The Company has agreed that, for a period of one
year, if required, after the date hereof, it will make the Prospectus available
to any broker-dealer for use in connection with any such resale. See "Plan of
Distribution."
 
     The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Old Notes in any jurisdiction in which
this Exchange Offer or the acceptance thereof would not be in compliance with
the securities or blue sky laws of such jurisdiction.
 
     By tendering in the Exchange Offer, each holder of Old Notes will represent
to the Company that, among other things, (i) the New Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Notes, whether or not such person is the holder, (ii)
neither the holder of Old Notes nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, (iii) if the holder is not a broker-dealer, or is a broker-dealer but
will not receive New Notes for its own account in exchange for Old Notes,
neither the holder nor any such other person is engaged in or intends to
participate in the distribution of such New Notes, and (iv) neither the holder
nor any such other person is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act or, if such holder is an "affiliate," that
such holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.
 
     Following the completion of the Exchange Offer, none of the Senior Notes
will be entitled to the contingent increase in interest rate provided pursuant
to the Old Notes. Following the consummation of the Exchange Offer, holders of
Senior Notes will not have any further registration rights, and the Old Notes
will continue to be subject to certain restrictions on transfer. See
"-- Consequences of Failure to Exchange." Accordingly, the liquidity of the
market for the Old Notes could be adversely affected. See "Risk Factors --
Consequences of the Exchange Offer on Non-Tendering Holders of the Old Notes."
 
     Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes are urged to
consult their financial and tax advisors in making their own decisions on
whether to participate in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
     General. Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and all
Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. Subject to the minimum denomination requirements
of the New Notes, the Company will issue (a) $1,000 principal amount of New
Notes due 2004 in exchange for each $1,000 principal amount of outstanding Old
Notes due 2004 accepted in the Exchange Offer, and (b) $1,000 principal amount
of New Notes due 2012 in exchange for each $1,000 principal amount of
 
                                       20
<PAGE>   25
 
outstanding Old Notes due 2012 accepted in the Exchange Offer. Holders may
tender some or all of their Old Notes pursuant to the Exchange Offer. However,
Old Notes may be tendered only in amounts that are integral multiples of $1,000
principal amount.
 
     The form and terms of the New Notes will be identical in all material
respects to the form and terms of the Old Notes except that (i) the New Notes
will be registered under the Securities Act and, therefore, will not bear
legends restricting the transfer thereof, and (ii) holders of the New Notes will
not be entitled to certain rights of holders of Old Notes under the Registration
Rights Agreement, which will terminate upon consummation of the Exchange Offer.
The New Notes will evidence the same debt as the Old Notes, will be entitled to
the benefits of the respective Indentures and each series will be treated as a
single class thereunder with any respective Old Notes that remain outstanding.
The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered for exchange.
 
     As of             , 1997, $150,000,000 aggregate principal amount of the
Old Notes due 2004 was outstanding and $150,000,000 aggregate principal amount
of Old Notes due 2012 was outstanding. This Prospectus, together with the Letter
of Transmittal, is being sent to the registered Holders of the Old Notes.
 
     Holders of Old Notes do not have any appraisal or dissenters' rights under
the Oklahoma General Corporation Act or the Indenture in connection with the
Exchange Offer. The Company intends to conduct the Exchange Offer in accordance
with the provisions of the Registration Rights Agreement and the applicable
requirements of the Exchange Act, and the rules and regulations of the
Commission thereunder. Old Notes which are not tendered for exchange in the
Exchange Offer will remain outstanding and interest thereon will continue to
accrue, but such Old Notes will not be entitled to any rights or benefits under
the Registration Rights Agreement.
 
     The Company will be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purposes of receiving the New Notes from the Company. If any tendered
Old Notes are not accepted for exchange because of an invalid tender, the
occurrence of certain other events set forth herein or otherwise, certificates
for any such unaccepted Old Notes will be returned, without expense, to the
tendering holder thereof as promptly as practicable after the Expiration Date.
 
     Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "-- Fees and Expenses."
 
     Expiration Date; Extensions; Amendments. The term "Expiration Date" shall
mean 5:00 p.m., New York City time, on             , 1997, unless the Company,
in its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended. Although the Company has no current intention to extend the
Exchange Offer, the Company reserves the right to extend the Exchange Offer at
any time and from time to time by giving oral or written notice to the Exchange
Agent and by timely public announcement communicated, unless otherwise required
by applicable law or regulation, by making a release to the Dow Jones News
Service. During any extension of the Exchange Offer, all Old Notes previously
tendered pursuant to the Exchange Offer and not withdrawn will remain subject to
the Exchange Offer. The date of the exchange of the New Notes for Old Notes will
be the first New York Stock Exchange trading day following the Expiration Date.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "-- Conditions of
the Exchange Offer" shall not have been satisfied, by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (ii) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in any manner determined by the Company to constitute
a material change, the Company will promptly disclose such amendment by means of
a prospectus supplement that will be distributed to the registered holders, and
 
                                       21
<PAGE>   26
 
the Company will extend the Exchange Offer for a period of time, depending upon
the significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such period.
 
     In all cases, issuance of the New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of a properly completed and duly executed Letter of
Transmittal and all other required documents; provided, however, that the
Company reserves the absolute right to waive any conditions of the Exchange
Offer or defects or irregularities in the tender of Old Notes. If any tendered
Old Notes are not accepted for any reason set forth in the terms and conditions
of the Exchange Offer or if Old Notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes or substitute Old Notes evidencing the unaccepted portion, as appropriate,
will be returned without expense to the tendering holder, unless otherwise
provided in the Letter of Transmittal, as promptly as practicable after the
expiration or termination of the Exchange Offer.
 
     Interest on the New Notes. Holders of Old Notes that are accepted for
exchange will not receive accrued interest thereon at the time of exchange.
However, each New Note will bear interest from the most recent date to which
interest has been paid on the Old Notes or New Notes, or if no interest has been
paid on the Old Notes or New Notes, from March 17, 1997.
 
     Procedures for Tendering Old Notes. The tender to the Company of Old Notes
by a holder thereof pursuant to one of the procedures set forth below will
constitute an agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal. A holder of the Old Notes may tender such Old Notes by (i) properly
completing and signing a Letter of Transmittal or a facsimile thereof (all
references in this Prospectus to a Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with any
corresponding certificate or certificates representing the Old Notes being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below), or (ii) complying with the guaranteed delivery procedures
described below.
 
     If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are to
be issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in DTC (also referred to as a book-entry facility) whose name
appears on a security listing as the owner of Old Notes), the signature of such
signer need not be guaranteed. In any other case, the tendered Old Notes must be
endorsed or accompanied by written instruments of transfer in form satisfactory
to the Company and duly executed by the registered holder and the signature on
the endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program
(SEMP). If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be guaranteed
by an Eligible Institution.
 
     THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT
TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
                                       22
<PAGE>   27
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish an account with respect
to the Old Notes at DTC for the purpose of facilitating the Exchange Offer, and
subject to the establishment thereof, any financial institution that is a
participant in DTC's system may make book-entry delivery of Old Notes by causing
DTC to transfer such Old Notes into the Exchange Agent's account with respect to
the Old Notes in accordance with DTC's procedure for such transfer. Although
delivery of the Old Notes may be effected through book-entry transfer into the
Exchange Agent's account at DTC, an appropriate Letter of Transmittal with any
required signature guarantee and all other required documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at the address
set forth in the Letter of Transmittal on or prior to the Expiration Date, or,
if the guaranteed delivery procedures described below are complied with, within
the time period provided under such procedures.
 
     A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at DTC), is received by the Exchange
Agent, or (ii) a Notice of Guaranteed Delivery or letter, telegram or facsimile
transmission to similar effect (as provided below) from an Eligible Institution
is received by the Exchange Agent. Issuances of New Notes in exchange for Old
Notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram
or facsimile transmission to similar effect (as provided below) by an Eligible
Institution will be made only against submission of a duly signed Letter of
Transmittal (and any other required documents) and deposit of the tendered Old
Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Notes. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Any Old Notes received by the Exchange Agent that are not validly
tendered and as to which the defects or irregularities have not been cured or
waived, or if Old Notes are submitted in principal amount greater than the
principal amount of Old Notes being tendered by such tendering holder, such
unaccepted or non-exchanged Old Notes will be returned by the Exchange Agent to
the tendering holder, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.
 
     In addition, the Company reserves the right in its sole discretion (a) to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date, and (b) to the extent permitted by applicable law, to
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers will differ from the terms
of the Exchange Offer.
 
     Guaranteed Delivery Procedures. If the holder desires to accept the
Exchange Offer and time will not permit a Letter of Transmittal or Old Notes to
reach the Exchange Agent before the Expiration Date or the procedure for
book-entry transfer cannot be completed on a timely basis, a tender may be
effected if the Exchange Agent has received at its office, on or prior to the
Expiration Date, a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
name(s) in which the Old Notes are registered and the certificate number(s) of
the Old Notes to be tendered, and stating that the tender is being made thereby
and guaranteeing that, within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, such Old Notes, in proper form for transfer (or a
confirmation of book-entry transfer of such Old Notes into the Exchange Agent's
account at DTC), will be delivered by such Eligible Institution together with a
properly completed and duly executed Letter of Transmittal (and any other
required documents). Unless Old Notes being tendered by the above-described
method are deposited with the Exchange Agent within the time period set forth
above (accompanied or preceded by a properly competed Letter of Transmittal and
any other required documents), the Company may, at its option, reject the
tender.
 
                                       23
<PAGE>   28
 
Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the purposes described in this paragraph are available from the
Exchange Agent.
 
     Terms and Conditions of the Letter of Transmittal. The Letter of
Transmittal contains, among other things, the following terms and conditions,
which are part of the Exchange Offer.
 
     The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The Transferor
represents and warrants that it has full power and authority to tender,
exchange, assign and transfer the Old Notes and to acquire New Notes issuable
upon the exchange of such tendered Old Notes, and that, when the same are
accepted for exchange, the Company will acquire good and unencumbered title to
the tendered Old Notes, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim. The Transferor also warrants
that it will, upon request, execute and deliver any additional documents deemed
by the Company to be necessary or desirable to complete the exchange, assignment
and transfer of tendered Old Notes or to transfer ownership of such Old Notes on
the account books maintained by DTC. All authority conferred by the Transferor
will survive the death, bankruptcy or incapacity of the Transferor and every
obligation of the Transferor shall be binding upon the heirs, personal
representatives, executors, administrators, successors, assigns, trustees in
bankruptcy and other legal representatives of such Transferor.
 
     By executing a Letter of Transmittal, each holder will make to the Company
the representations set forth above under the heading "-- Purpose and Effect of
the Exchange Offer."
 
     Withdrawal of Tenders of Old Notes. Except as otherwise provided herein,
tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.
 
     To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) contain a statement that
such holder is withdrawing its election to have such Old Notes exchanged, (iv)
be signed by the holder in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Old Notes register the
transfer of such Old Notes in the name of the person withdrawing the tender, and
(v) specify the name in which any such Old Notes are to be registered, if
different from that of the Depositor. If Old Notes have been tendered pursuant
to the procedure for book-entry transfer, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, whose determination shall be
final and binding on all parties. Any Old Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer and no New
Notes will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the holder thereof without cost to
such holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following one of the procedures described above under
"-- Procedures for Tendering Old Notes" at any time prior to the Expiration
Date.

CONDITIONS OF THE EXCHANGE OFFER
 
     Notwithstanding any other term of the Exchange Offer, or any extension of
the Exchange Offer, the Company shall not be required to accept for exchange, or
exchange New Notes for, any Old Notes, and may terminate the Exchange Offer as
provided herein before the acceptance of such Old Notes, if:
 
          (a) any statute, rule or regulation shall have been enacted, or any
     action shall have been taken by any court or governmental authority which,
     in the reasonable judgment of the Company, would prohibit, restrict or
     otherwise render illegal consummation of the Exchange Offer; or
 
          (b) any change, or any development involving a prospective change, in
     the business or financial affairs of the Company or any of its subsidiaries
     has occurred which, in the sole judgment of the Company, might materially
     impair the ability of the Company to proceed with the Exchange Offer or
     materially impair the contemplated benefits of the Exchange Offer to the
     Company; or
 
          (c) there shall occur a change in the current interpretations by the
     staff of the Commission which, in the Company's reasonable judgment, might
     materially impair the Company's ability to proceed with the Exchange Offer.
 
     If the Company determines in its sole discretion that any of the above
conditions are not satisfied, the Company may (i) refuse to accept any Old Notes
and return all tendered Old Notes to the tendering holders, (ii) extend the
Exchange Offer and retain all Old Notes tendered prior to the Expiration Date,
subject, however, to the right of holders to withdraw such Old Notes (see
"-- Terms of the Exchange Offer -- Withdrawal of Tenders of Old Notes"), or
(iii) waive such unsatisfied conditions with respect to the Exchange Offer and
accept all validly tendered Old Notes which have not been withdrawn. If such
waiver constitutes a material change to the Exchange Offer, the Company will
promptly disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and the Company will extend the Exchange
Offer for a period of time, depending upon the significance of the waiver and
the manner of disclosure to the registered holders, if the Exchange Offer would
otherwise expire during such period.

</TABLE>
 
FEES AND EXPENSES
 
     The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telecopy, telephone or in person by officers and
 
                                       25
<PAGE>   30
 
regular employees of the Company and its affiliates. No additional compensation
will be paid to any such officers and employees who engage in soliciting
tenders.
 
     The Company has not retained any dealer-manager or other soliciting agent
in connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptance of the Exchange Offer. The Company,
however, will pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses in
connection therewith. The Company may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, the Letter of
Transmittal and related documents to the beneficial owners of the Old Notes and
in handling or forwarding tenders for exchange.
 
     The expenses to be incurred in connection with the Exchange Offer will be
paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and transfer agent and registrar, accounting and legal fees and printing
costs, among others.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of the Old Notes pursuant to the Exchange Offer. If, however, New Notes, or Old
Notes for principal amounts not tendered or accepted for exchange, are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered or if a transfer tax is imposed for
any reason other than the exchange of the Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities within the meaning of Rule 144 of the
Securities Act. Accordingly, such Old Notes may be offered, resold, pledged or
otherwise transferred only (i) to the Company, (ii) to a person who the
transferor reasonably believes is a qualified institutional buyer in compliance
with Rule 144A, (iii) pursuant to the exemption from registration provided by
Rule 144 under the Securities Act (if available), (iv) outside the United States
to a foreign person in compliance with Rule 904 under the Securities Act, (v) in
accordance with another exemption from the registration requirements of the
Securities Act (and based upon an opinion of counsel if the Company so requests)
or (vi) pursuant to an effective registration statement under the Securities
Act. The liquidity of the Old Notes could be adversely affected by the Exchange
Offer. Following the consummation of the Exchange Offer, holders of the Old
Notes will have no further registration rights under the Registration Rights
Agreement and will not be entitled to the contingent increase in the interest
rate provided for in the Old Notes.
 
ACCOUNTING TREATMENT
 
     The New Notes will be recorded at the same carrying value as the Old Notes,
as reflected in the Company's accounting records on the date of the exchange.
Accordingly, no gain or loss for accounting purposes will be recognized by the
Company. The costs of the Exchange Offer and the unamortized expenses related to
the issuance of the Old Notes will be amortized over the term of the New Notes.
 
                                USE OF PROCEEDS
 
     The Company will not receive any proceeds from the issuance of the New
Notes offered hereby. In consideration for issuing the New Notes as contemplated
in this Prospectus, the Company will receive in exchange Old Notes in like
principal amount, the term and form of which are identical in all material
respects to the New Notes. The Old Notes surrendered in exchange for New Notes
will be retired and canceled and cannot be reissued. Accordingly, issuance of
the New Notes will not result in any increase in the indebtedness of the
Company.

Company and its subsidiaries at December 31, 1996 and as adjusted to give effect

     The following summaries of the Existing Notes Indentures do not purport to
be complete and are subject to, and qualified in their entirety by reference to,
the applicable Existing Notes Indentures. Capitalized terms used herein but not
defined have the meanings assigned to such terms in the applicable Existing
Notes Indenture.
 
     General. The Company presently has outstanding $90 million in aggregate
principal amount of 10 1/2% Notes which mature on June 1, 2002, and $120 million
in aggregate principal amount of 9 1/8% Notes which mature on April 15, 2006.
The 10 1/2% Notes bear interest at an annual rate of 10 1/2%, payable
semiannually on each June 1 and December 1 and the 9 1/8% Notes bear interest at
an annual rate of 9 1/8%, payable semiannually on each April 15 and October 15.
The Existing Notes are senior, unsecured obligations of the Company that rank
pari passu in right of payment with all existing and future Senior Indebtedness
of the Company and rank senior in right of payment to all existing and future
subordinated indebtedness of the Company. The Existing Notes are fully and
unconditionally guaranteed, jointly and severally, by the Restricted
Subsidiaries.
 
     Optional Redemption. At any time on or after June 1, 1999, the Company may,

     Notwithstanding the foregoing, in the event the Company consummates one or
more Equity Offerings on or prior to June 1, 1998, the Company, at its option,
may redeem up to $30 million of the aggregate principal amount of the 10 1/2%
Notes with all or a portion of the aggregate net proceeds received by the
Company from such Equity Offerings at a redemption price of 110% of the
aggregate principal amount of the 10 1/2% Notes so redeemed, plus accrued and
unpaid interest thereon to the redemption date; provided, however, that
following such redemption, at least $60 million of the aggregate principal
amount of the 10 1/2% Notes remains outstanding.
 
     At any time on or after April 15, 2001, the Company may, at its option,
redeem all or any portion of the 9 1/8% Notes at the redemption prices
(expressed as percentages of the principal amount of the 9 1/8% Notes) set forth

     Change of Control. The Existing Notes Indentures provide that, following
the occurrence of any Change of Control, the Company must offer to purchase all
outstanding Existing Notes at a purchase price equal to 101% of the aggregate
principal amount of the Existing Notes, plus accrued and unpaid interest to the
date of purchase.
 
     Restrictive Covenants. The Existing Notes Indentures contain restrictive
covenants that limit the Company and its Restricted Subsidiaries with respect to
certain matters, including changes in business, liens, debt, mergers, dividends,
investments, sale and leaseback transactions, transactions with affiliates, and
sales of assets. In the event of certain asset dispositions, the Company will be
required, under certain circumstances, to use Excess Proceeds to offer to
purchase Existing Notes at 100% of the principal amount thereof, plus accrued
and unpaid interest. The Existing Notes Indenture applicable to the 10 1/2%
Notes (the "10 1/2% Notes Indenture") prohibits the Company and any Restricted
Subsidiary from incurring Indebtedness, other than Permitted Indebtedness,
unless (i) the Adjusted Consolidated EBITDDA Coverage Ratio is at least
2.5-to-1.0, and (ii) ACNTA is at least 125% of Indebtedness of the Company and
its Restricted Subsidiaries. The 10 1/2% Notes Indenture permits the Company and
its Restricted Subsidiaries to incur Permitted Indebtedness under a bank credit
facility not in excess of the greater of $15 million and 15% of ACNTA. The
Existing Notes Indenture applicable to the 9 1/8% Notes (the "9 1/8% Notes
Indenture") prohibits the Company and any Restricted Subsidiary from incurring
Indebtedness, other than Permitted Indebtedness, unless (i) the Adjusted
Consolidated EBITDA Coverage Ratio is at least 2.5-to-1.0, or (ii) ACNTA is at
least 200% of Indebtedness of the Company and its Restricted Subsidiaries. The
9 1/8% Notes Indenture permits the Company and its Restricted Subsidiaries to
incur Permitted Indebtedness under a bank credit facility not in excess of the
greater of (a) $75 million and (b) $30 million plus 15% of ACNTA.
 
                          DESCRIPTION OF SENIOR NOTES
 
     The Company will issue up to $150 million aggregate principal amount of New
Notes due 2004 and up to $150 million of New Notes due 2012 (less the aggregate
principal amount of Old Notes that are not exchanged), pursuant to separate
Indentures, each dated as of March 15, 1997 among the Company, the Restricted
Subsidiaries and United States Trust Company of New York, as trustee (the
"Trustee"). A copy of each Indenture is available upon request from the Company
and is filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The following summaries of certain provisions of the
Senior Notes, including the New Notes, and the Indentures do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, the Senior Notes and the Indentures, including the definitions therein of
certain capitalized terms used but not defined herein.
 
GENERAL
 
     The aggregate principal amount of the Senior Notes is limited to
$300,000,000, consisting of $150,000,000 principal amount of New Notes due 2004
and Old Notes due 2004 (together, the "Senior Notes due 2004") and $150,000,000
principal amount of New Notes due 2012 and Old Notes due 2012 (together, the
"Senior Notes due 2012"). Each Senior Note due 2004 will mature on March 15,
2004 and will bear interest at an annual rate of 7 7/8% per annum. Each Senior
Note due 2012 will mature on March 15, 2012 and will bear interest at an annual
rate of 8 1/2% per annum. Interest on the Senior Notes will accrue from their
respective dates of original issuance, payable semiannually in arrears on March
15 and September 15 of each year, commencing September 15, 1997, to the Person
in whose name the Senior Note is registered at the close of business on March 1
or September 1 preceding such interest payment date. Interest will be computed
on the basis of a 360-day year of twelve 30-day months. Principal, premium, if
any, and interest will be payable at the offices of the Trustee and the Paying
Agent, provided that, at the option of the Company, payment of interest may be
made by check mailed to the address of the Person entitled thereto as it appears
in the register of the Senior Notes maintained by the Registrar. Initially, the
Trustee will also act as Paying Agent and Registrar for the Senior Notes.
 
     The Senior Notes are senior unsecured obligations of the Company. The
Senior Notes rank pari passu in right of payment with all existing and future
Pari Passu Indebtedness of the Company and rank senior in right
 
                                       29
<PAGE>   34
 
of payment to all existing and future Subordinated Indebtedness of the Company.
At December 31, 1996, on a pro forma basis after giving effect to the sale of
the Old Notes and the application of the net proceeds therefrom, the Company and
its Restricted Subsidiaries would have had Pari Passu Indebtedness in addition
to the Senior Notes of approximately $215.7 million, of which $5.6 million was
secured by certain assets of the Company, and no Indebtedness would have ranked
junior to the Senior Notes in right of payment.
 
GUARANTEES
 
     All of the subsidiaries of the Company other than CEM and Chesapeake Canada
Corporation have fully and unconditionally guaranteed, on a joint and several
basis, the Company's obligations to pay principal of, premium, if any, and
interest on the Senior Notes. Each of the Indentures provides that each Person
other than a Foreign Subsidiary that becomes a Restricted Subsidiary after the
Issue Date will guarantee the payment of the Senior Notes. Each of the
Guarantees is a senior obligation of the Subsidiary Guarantors providing such
Guarantee, and ranks pari passu in right of payment with all existing and future
Pari Passu Indebtedness of such Subsidiary Guarantor, except to the extent of
collateral securing such Pari Passu Indebtedness, and ranks senior to all
existing and future Subordinated Indebtedness of such Subsidiary Guarantor. The
Guarantees rank pari passu in right of payment with the guarantees by the
Subsidiary Guarantors of the Existing Notes.
 
     The obligations of each Subsidiary Guarantor are limited to the amount as
will, after giving effect to all other contingent and fixed liabilities of such
Subsidiary Guarantor and after giving effect to any collections from or payments
made by or on behalf of any other Subsidiary Guarantor in respect of the
obligations of such other Subsidiary Guarantor under its Guarantee or pursuant
to its contribution obligations under the Indentures, result in the obligations
of such Subsidiary Guarantor under its Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal, state or foreign law. Each
Subsidiary Guarantor that makes a payment or distribution under a Guarantee
shall be entitled to a contribution from each other Subsidiary Guarantor in a
pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor.
 
     Each of the Indentures provides that, subject to the next succeeding
paragraph, no Subsidiary Guarantor may consolidate or merge with or into
(whether or not such Subsidiary Guarantor is the surviving entity or Person)
another corporation, entity or Person unless (i) the entity or Person formed by
or surviving any such consolidation or merger (if other than such Subsidiary
Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to
a supplemental indenture, in a form reasonably satisfactory to the Trustee,
under the Senior Notes to which such Indenture relates and such Indenture, and
(ii) immediately after such transaction, no Default or Event of Default exists.
The foregoing will not prohibit a merger between Subsidiary Guarantors or a
merger between the Company and a Subsidiary Guarantor.
 
     Each of the Indentures provides that in the event of a sale or other
disposition of all or substantially all of the assets of any Subsidiary
Guarantor, by way of merger, consolidation or otherwise, or a sale or other
disposition of all of the capital stock or other ownership interests of such
Subsidiary Guarantor, or a Subsidiary ceases to be a Subsidiary Guarantor, then
such Subsidiary (in the event of a sale or other disposition, by way of such a
merger, consolidation or otherwise, of all of the capital stock or other
ownership interests of such Subsidiary) or the corporation acquiring the
property (in the event of a sale or other disposition of all or substantially
all of the assets of such Subsidiary) will be released and relieved of any
obligations under its Guarantees. In addition, each of the Indentures provides
that if, at any time while Senior Notes to which such Indenture relates remain
outstanding, none of the Company's then outstanding Pari Passu Indebtedness
(other than Senior Notes) is guaranteed by a Subsidiary Guarantor, such
Subsidiary Guarantor shall be released and relieved of any obligations under its
Guarantees (which shall be terminated and cease to have any force and effect).
The Indentures provide that if any Subsidiary of the Company that is not a
Subsidiary Guarantor guarantees any Funded Indebtedness of the Company at any
time in the future, then the Company will cause the Senior Notes to be equally
and ratably guaranteed by such Subsidiary.

OPTIONAL REDEMPTION
 
     Senior Notes. The Company may at any time prior to March 15, 2004, at its
option, redeem all or any portion of either series of the Senior Notes at the
Make-Whole Price plus accrued and unpaid interest to the date of redemption.
 
     Senior Notes due 2012. At any time on or after March 15, 2004, the Company
may, at its option, redeem all or any portion of the Senior Notes due 2012 at
the redemption prices (expressed as percentages of the principal amount of the
Senior Notes due 2012) set forth below, plus, in each case, accrued and unpaid
interest thereon to the applicable redemption date, if redeemed during the
twelve-month period beginning March 15 of the years indicated below:
 
<TABLE>
<CAPTION>
                       YEAR                         PERCENTAGE
                       ----                         ----------
<S>                                                 <C>
2004..............................................   104.25%
2005..............................................   103.40%
2006..............................................   102.55%
2007..............................................   101.70%
2008..............................................   100.85%
2009 and thereafter...............................   100.00%
</TABLE>
 
     If less than all of a series of the Senior Notes are to be redeemed at any
time, selection of Senior Notes of such series for redemption will be made by
the Trustee on a pro rata basis, by lot or by any other method that the Trustee
considers fair and appropriate and that complies with the requirements of any
securities exchange on which such series of the Senior Notes may be listed,
provided that no Senior Notes with a principal amount of $1,000 or less will be
redeemed in part. Notice of redemption will be mailed by first class mail at
least 30 but not more than 60 days before the redemption date to each Holder of
Senior Notes to be redeemed at its registered address. If any Senior Note is to
be redeemed in part only, the notice of redemption that relates to such Senior
Note will state the portion of the principal amount thereof to be redeemed. A
new Senior Note in a principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Senior Note. On and after the redemption date interest ceases to accrue
on Senior Notes or portions of them called for redemption.
 
CERTAIN COVENANTS
 
     Nothing in either of the Indentures or either series of the Senior Notes
will in any way limit the amount of Indebtedness or securities (other than the
Senior Notes) that the Company or any of its Subsidiaries may incur or issue.
The Indentures provide that the following restrictive covenants will be
applicable to the Company and its Restricted Subsidiaries.
 
     Limitation on Liens. The Indentures will provide that the Company will not,
and will not permit any Restricted Subsidiary to, issue, assume or guarantee any
Indebtedness for borrowed money secured by any Lien on any property or asset now
owned or hereafter acquired by the Company or such Restricted Subsidiary without
making effective provision whereby any and all Senior Notes then or thereafter
outstanding will be secured by a Lien equally and ratably with any and all other
obligations thereby secured for so long as any such obligations shall be so
secured.
 
     The foregoing restriction will not, however, apply to:
 
          (a) Liens existing on the date on which the Senior Notes are
     originally issued or provided for under the terms of agreements existing on
     such date;
 
          (b) Liens on property securing (i) all or any portion of the cost of
     exploration, drilling or development of such property, (ii) all or any

     repairing any property or assets, real or personal, or improvements used or
     to be used in connection with such property or (iii) Indebtedness incurred
     by the Company or any Restricted Subsidiary to provide funds for the
     activities set forth in clauses (i) and (ii) above;
 
                                       31

          (c) Liens securing Indebtedness owed by a Restricted Subsidiary to the
     Company or to any other Restricted Subsidiary;
 
          (d) Liens on property existing at the time of acquisition of such
     property by the Company or a Subsidiary or Liens on the property of any
     corporation or other entity existing at the time such corporation or other
     entity becomes a Restricted Subsidiary of the Company or is merged with the
     Company in compliance with the Indentures and in either case not incurred
     as a result of (or in connection with or in anticipation of) the
     acquisition of such property or such corporation or other entity becoming a
     Restricted Subsidiary of the Company or being merged with the Company,
     provided that such Liens do not extend to or cover any property or assets
     of the Company or any of its Restricted Subsidiaries other than the
     property so acquired;
 
          (e) Liens on any property securing (i) Indebtedness incurred in
     connection with the construction, installation or financing of pollution
     control or abatement facilities or other forms of industrial revenue bond
     financing or (ii) Indebtedness issued or guaranteed by the United States or
     any State thereof or any department, agency or instrumentality of either;
 
          (f) any Lien extending, renewing or replacing (or successive
     extensions, renewals or replacements of) any Lien of any type permitted
     under clauses (a) through (e) above, provided that such Lien extends to or
     covers only the property that is subject to the Lien being extended,
     renewed or replaced;
 
          (g) certain Liens arising in the ordinary course of business of the
     Company and the Restricted Subsidiaries;
 
          (h) any Lien resulting from the deposit of moneys or evidences of
     indebtedness in trust for the purpose of defeasing Indebtedness of the
     Company or any Restricted Subsidiary; or
 
          (i) Liens (exclusive of any Lien of any type otherwise permitted under
     clauses (a) through (h) above) securing Indebtedness of the Company or any
     Restricted Subsidiary in an aggregate principal amount which, together with
     the aggregate amount of Attributable Indebtedness deemed to be outstanding
     in respect of all Sale/Leaseback Transactions entered into pursuant to
     clause (a) of the covenant described under "Limitation on Sale/Leaseback
     Transactions" below (exclusive of any such Sale/Leaseback Transactions
     otherwise permitted under clauses (a) through (h) above), does not at the
     time such Indebtedness is incurred exceed 15% of ACNTA.
 
     The following types of transactions will not be prohibited or otherwise
limited by the foregoing covenant: (i) the sale, granting of Liens with respect
to, or other transfer of, crude oil, natural gas or other petroleum hydrocarbons
in place for a period of time until, or in an amount such that, the transferee
will realize therefrom a specified amount (however determined) of money or of
such crude oil, natural gas or other petroleum hydrocarbons; (ii) the sale or
other transfer of any other interest in property of the character commonly
referred to as a production payment, overriding royalty, forward sale or similar
interest; (iii) the entering into of Currency Hedge Obligations, Interest Rate

Indebtedness for borrowed money that is the subject of any such obligation shall
not be permitted hereby unless permitted under clauses (a) through (i) above;
and (iv) the granting of Liens required by any contract or statute in order to
permit the Company or any Restricted Subsidiary to perform any contract or
subcontract made by it with or at the request of the United States or any State
thereof or any department, agency or instrumentality of either, or to secure
partial, progress, advance or other payments to the Company or any Restricted
Subsidiary by such governmental unit pursuant to the provisions of any contract
or statute.
 
     Limitation of Sale/Leaseback Transactions. The Indentures will provide that
the Company will not, and will not permit any Restricted Subsidiary to, enter
into any Sale/Leaseback Transaction with any person (other than the Company or a
Restricted Subsidiary) unless:
 
          (a) the Company or such Restricted Subsidiary would be entitled to
     incur Indebtedness, in a principal amount equal to the Attributable
     Indebtedness with respect to such Sale/Leaseback Transaction, secured by a
     Lien on the property subject to such Sale/Leaseback Transaction pursuant to
     the
 
                                       32
<PAGE>   37
 
     covenant described under "-- Limitation on Liens" above without equally and
     ratably securing the Senior Notes pursuant to such covenant;
 
          (b) after the date on which the Senior Notes are originally issued and
     within a period commencing six months prior to the consummation of such
     Sale/Leaseback Transaction and ending six months after the consummation
     thereof, the Company or such Restricted Subsidiary shall have expended for
     property used or to be used in the ordinary course of business of the
     Company and the Restricted Subsidiaries (including amounts expended for the
     exploration, drilling or development thereof, and for additions,
     alterations, repairs and improvements thereto) an amount equal to all or a
     portion of the net proceeds of such Sale/Leaseback Transaction and the
     Company shall have elected to designate such amount as a credit against
     such Sale/Leaseback Transaction (with any such amount not being so
     designated to be applied as set forth in clause (c) below); or
 
          (c) the Company, during the twelve-month period after the effective
     date of such Sale/Leaseback Transaction, shall have applied to the
     voluntary defeasance or retirement of a series of Senior Notes or any Pari
     Passu Indebtedness an amount equal to the greater of the net proceeds of
     the sale or transfer of the property leased in such Sale/Leaseback
     Transaction and the fair value, as determined by the Board of Directors of
     the Company, of such property at the time of entering into such
     Sale/Leaseback Transaction (in either case adjusted to reflect the
     remaining term of the lease and any amount expended by the Company as set
     forth in clause (b) above), less an amount equal to the principal amount of
     Senior Notes and Pari Passu Indebtedness voluntarily defeased or retired by
     the Company within such twelve-month period and not designated as a credit
     against any other Sale/Leaseback Transaction entered into by the Company or
     any Restricted Subsidiary during such period.
 
     Limitations on Mergers and Consolidations. The Indentures will provide that
the Company will not consolidate or merge with or into any Person, or sell,
lease, convey or otherwise dispose of all or substantially all of its assets, or
assign any of its obligations under the Indentures or under the Senior Notes, to
any Person, unless: (i) the Person formed by or surviving such consolidation or
merger (if other than the Company), or to which such sale, lease, conveyance or
other disposition or assignment shall be made (collectively, the "Successor"),
is a corporation organized and existing under the laws of the United States or
any State thereof or the District of Columbia, or Canada or any Province
thereof, and the Successor assumes by supplemental indenture in a form
satisfactory to the Trustee all of the obligations of the Company under the
Indentures and under the Senior Notes; and (ii) immediately after giving effect
to such transaction, no Event of Default shall have occurred and be continuing.
 
     SEC Reports. Notwithstanding that the Company may not be required to remain
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company will file with the SEC and provide the Trustee and Holders with
annual reports and such information, documents and other reports specified in
Sections 13 and 15(d) of the Exchange Act.
 
CERTAIN DEFINITIONS
 
     The following is a summary of certain defined terms to be used in the
Indentures. Reference is made to the Indentures for the full definition of all
such terms and for the definitions of capitalized terms used herein and not
defined below.
 
     "Adjusted Consolidated Net Tangible Assets" or "ACNTA" means, without
duplication, as of the date of determination, (a) the sum of (i) discounted
future net revenue from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines before any
state or federal income taxes, as estimated by independent petroleum engineers
in a reserve report prepared as of the end of the Company's most recently
completed fiscal year, as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of
the Company and its Restricted Subsidiaries attributable to any acquisition
consummated since the date of such year-end reserve report and (B) estimated oil
and gas reserves of the Company and its Restricted Subsidiaries attributable to
extensions, discoveries and other additions and upward revisions of estimates of
proved oil and gas reserves due to exploration, development or exploitation,
production or other activities conducted or otherwise occurring since
 
                                       33
<PAGE>   38
 
the date of such year-end reserve report which, in the case of sub-clauses (A)
and (B), would, in accordance with standard industry practice, result in such
increases as calculated in accordance with SEC guidelines (utilizing the prices
utilized in such year-end reserve report), and decreased by, as of the date of
determination, the discounted future net revenue of (C) estimated proved oil and
gas reserves of the Company and its Restricted Subsidiaries produced or disposed
of since the date of such year-end reserve report and (D) reductions in the
estimated oil and gas reserves of the Company and its Restricted Subsidiaries
since the date of such year-end reserve report attributable to downward
revisions of estimates of proved oil and gas reserves due to exploration,
development or exploitation, production or other activities conducted or
otherwise occurring since the date of such year-end reserve report which, in the
case of sub-clauses (C) and (D) would, in accordance with standard industry
practice, result in such decreases as calculated in accordance with SEC

revenue, calculated in accordance with SEC guidelines, attributable to reserves
subject to Dollar-Denominated Production Payments which, based on the estimates
of production included in determining the discounted future net revenue
specified in (a)(i) above (utilizing the same prices utilized in the Company's

obligations of the Company and its Restricted Subsidiaries with respect to

assessments, water rates or similar charges. In the case of any lease which is
terminable by the lessee upon payment of a penalty, such net amount of rent
shall also include the amount of such penalty, but no rent shall be considered
as required to be paid under such lease subsequent to the first date upon which
it may be so terminated.

EVENTS OF DEFAULT
 
     An Event of Default is defined in each Indenture as being: (i) default by

if any, or interest on the Senior Notes) if the Trustee considers it in the
interest of the Holders of the Senior Notes to do so.
 
     Each of the Indentures provides that if an Event of Default occurs and is
continuing with respect to the Indenture, the Trustee or the Holders of not less

                                       38
<PAGE>   43

of the Senior Notes. The amount due and payable on the acceleration of any
Senior Note will be equal to 100% of the principal amount of such Senior Note,
plus accrued and unpaid interest to the date of payment. Under certain
circumstances, the Holders of a majority in principal amount of the outstanding
series of Senior Notes may rescind any such acceleration with respect to such
series of Senior Notes and its consequences.

such notice, request and offer of indemnity and (v) no direction inconsistent
with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in principal amount of such series of Senior
Notes; provided, however, such provision does not affect the right of a Holder
of a Senior Note to sue for enforcement of any overdue payment thereon.
 
     The Holders of a majority in principal amount of each series of the Senior
Notes then outstanding will have the right to direct the time, method and place
of conducting any proceeding for exercising any remedy available to the Trustee
under the Indenture relating to such series of Senior Notes, subject to certain
limitations specified in such Indenture. Each of the Indentures will require the
annual filing by the Company with the Trustee of a written statement as to
compliance with the covenants contained in such Indenture.

Holders of a majority in principal amount of such series of Senior Notes then
outstanding; provided that no such modification or amendment may, without the
consent of the Holder of each Senior Note of such series then outstanding
affected thereby, (i) reduce the percentage of principal amount of Senior Notes
of such series whose Holders must consent to an amendment, supplement or waiver;
(ii) reduce the rate or change the time for payment of interest, including
default interest, on any such Senior Note; (iii) reduce the principal amount of

percentage of principal amount of Senior Notes necessary to waive compliance
with certain provisions of the Indenture; or (viii) waive a continuing Default
or Event of Default in the payment of principal of, premium, if any, or interest
on such series of the Senior Notes. Each of the Indentures will provide that
modifications and amendments of such Indenture may be made by the Company and
the Trustee without the consent of any holders of the Senior Notes to which such
Indenture relates in certain limited circumstances, including (a) to cure any
ambiguity, omission, defect or inconsistency, (b) to provide for the assumption
of the obligations of the Company or any Subsidiary Guarantor under such
Indenture upon the merger, consolidation or sale or other disposition of all or
substantially all of the assets of the Company or such Subsidiary Guarantor, (c)
to reflect the release of any Subsidiary Guarantor from its Guarantee, or the
addition of any Subsidiary of the Company as a Subsidiary Guarantor, in the
manner provided in such Indenture, (d) to comply with any requirement of the SEC
in order to effect or maintain the qualification of such Indenture under the
Trust Indenture Act of 1939 or (e) to make any change that would
 
                                       39
<PAGE>   44
 
provide any additional benefit to the Holders or that does not adversely affect
the rights of any Holder of Senior Notes in any material respect.
 
     Each of the Indentures provides that the Holders of a majority in aggregate
principal amount of the Senior Notes then outstanding may waive any past default
under such Indenture, except a default in the payment of principal premium, if
any, or interest.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding Senior Notes of either
series ("Legal Defeasance"). Such Legal Defeasance means that the Company will
be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Senior Notes of such series, except for (i) the rights of Holders of
such Senior Notes to receive payments in respect of the principal of, premium,
if any, and interest on such Senior Notes when such payments are due, (ii) the
Company's obligations with respect to such Senior Notes concerning the issuance
of temporary Senior Notes, transfers and exchanges of such Senior Notes,
replacement of mutilated, destroyed, lost or stolen Senior Notes, the
maintenance of an office or agency where such Senior Notes may be surrendered
for transfer or exchange or presented for payment, and duties of paying agents,
(iii) the rights, powers, trusts, duties and immunities of the Trustee, and the
Company's obligations in connection therewith and (iv) the Legal Defeasance
provisions of the Indenture. In addition, the Company may, at its option and at
any time, elect to have the obligations of the Company released with respect to
certain covenants described under "-- Certain Covenants" ("Covenant
Defeasance"), and thereafter any omission to comply with such obligations shall
not constitute a Default or Event of Default with respect to the Senior Notes.
In the event Covenant Defeasance occurs, certain events (not including
non-payment or bankruptcy and insolvency events) described under "-- Events of
Default" will no longer constitute an Event of Default with respect to the
Senior Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of a series of Senior Notes, cash in U.S. Legal Tender,
non-callable U.S. Government Securities, or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Senior Notes of such series on the Maturity Date or
on the applicable mandatory redemption date, as the case may be, of such
principal or installment of principal, premium, if any, or interest; (ii) in the
case of Legal Defeasance, the Company must deliver to the Trustee an opinion of
counsel reasonably acceptable to the Trustee confirming that (A) the Company has
received from or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of such 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 the
outstanding Senior Notes of such series will not recognize income, gain or loss
for federal income tax purposes as a result of such Legal 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 Legal Defeasance had not
occurred; (iii) in the case of Covenant Defeasance, the Company shall have
delivered to the Trustee an opinion of counsel reasonably acceptable to the
Trustee to the effect that the Holders of the related series of outstanding
Senior Notes 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; (iv) no
Default or Event of Default shall have occurred and be continuing on the date of
such deposit or insofar as Events of Default from bankruptcy or insolvency
events are concerned, at any time in the period ending on the 91st day after the
date of deposit; (v) such Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute a default under the Indenture
or any other material agreement or instrument to which the Company is a party or
by which the Company is bound; (vi) the Company shall have delivered to the
Trustee an Officers' Certificate stating that the deposit was not made by the
Company with the intent of preferring the holders of such series of Senior Notes
over other creditors of the Company or with the intent of defeating, hindering,

<PAGE>   45
 
Officers' Certificate and an opinion of counsel each stating that all conditions
precedent provided for relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.
 
GOVERNING LAW
 
     Each of the Indentures provides that it will be governed by, and construed
in accordance with, the laws of the State of New York, but without giving effect
to principles of conflicts of law to the extent that the application of the law
of another jurisdiction would be required thereby.
 
THE TRUSTEE
 
     United States Trust Company of New York is the Trustee under each of the
Indentures. Its address is 114 West 47th Street, New York, New York 10036-1532.
The Company has also appointed the Trustee as the initial Registrar, Transfer
Agent and Paying Agent under the Indentures.
 
     The Trustee is permitted to become an owner or pledgee of Senior Notes and
may otherwise deal with the Company or its Subsidiaries or Affiliates with the
same rights it would have if it were not Trustee. If, however, the Trustee
acquires any conflicting interest (as defined in the Trust Indenture Act of
1939), it must eliminate such conflict or resign.
 
     Each of the Indentures provides that in case an Event of Default shall
occur (and be continuing), the Trustee will be required to use the degree of
care and skill of a prudent person in the conduct of such person's own affairs.
The Trustee will be under no obligation to exercise any of its powers under
either of the Indentures at the request of any of the Holders of the Senior
Notes to which such Indenture relates, unless such Holders have offered the
Trustee indemnity reasonably satisfactory to it.
 
BOOK-ENTRY SYSTEM
 
  Book-Entry, Delivery and Form
 
     The certificates representing each of the New Notes due 2004 and the New
Notes due 2012 will initially be represented by one or more permanent global
Senior Notes in definitive, fully registered form without interest coupons (each
a "Global Note") and will be deposited with the Trustee as custodian for, and
registered in the name of, a nominee of DTC. Except in the limited circumstances
described below under "Certificated Senior Notes," owners of beneficial
interests in a Global Note will not be entitled to receive physical delivery of
Certificated Senior Notes (as defined below).
 
     Ownership of beneficial interests in a Global Note will be limited to
persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in a Global
Note will be shown on, and the transfer of that ownership will be effected only
through, records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants).
 
     So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Senior Notes represented by such Global Note for all
purposes under the applicable Indenture and the Senior Notes. No beneficial
owner of an interest in a Global Note will be able to transfer that interest
except in accordance with the applicable procedures of DTC, in addition to those
provided for under the applicable Indenture.
 
     Payments of the principal of, and interest on, a Global Note will be made
to DTC or its nominee, as the case may be, as the registered owner thereof.
Neither the Company, the Trustee nor any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
     The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or
 
                                       41
<PAGE>   46
 
its nominee. The Company also expects that payments by participants to owners of
beneficial interests in such Global Note held through such participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.
 
     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.
 
     The Company expects that DTC will take any action permitted to be taken by
a holder of Senior Notes (including the presentation of Senior Notes for
exchange as described below) only at the direction of one or more participants
to whose account the DTC interests in a Global Note are credited and only in
respect of such portion of the aggregate principal amount of Senior Notes as to
which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Senior Notes, DTC will
exchange the applicable Global Note for Certificated Senior Notes, which it will
distribute to its participants.
 
     The Company understands that DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A under the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical movement
of certificates and certain other organizations. Indirect access to the DTC
system is available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").
 
     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in a Global Note among participants it is
under no obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Neither the Company nor the Trustee
will have any responsibility for the performance by DTC or its participants or
indirect participants of their respective obligations under the rules and
procedures governing their operations.
 
  Certificated Senior Notes
 
     Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the Trustee, exchange such beneficial interest
for Senior Notes in the form of certificated Senior Notes ("Certificated Senior
Notes"). Upon any such issuance, the Trustee is required to register such
Certificated Senior Notes in the name of, and cause the same to be delivered to,
such person or persons (or the nominee of any thereof). In addition, if (i) the
Company notifies the Trustee in writing that the Depositary is no longer willing
or able to act as a depositary and the Company is unable to locate a qualified
successor within 90 days or (ii) the Company, at its option, notifies the
Trustee in writing that it elects to cause the issuance of Senior Notes in the
form of Certificated Senior Notes under the Indentures, then, upon surrender by
the Global Note holder of its Global Note, Senior Notes in such form will be
issued to each person that the Global Note holder and the Depositary identify as
being the beneficial owner of the related Senior Notes.
 
     Neither the Company nor the Trustee will be liable for any delay by the
Global Note holder or the Depositary in identifying the beneficial owners of
Senior Notes and the Company and the Trustee may conclusively rely on, and will
be protected in relying on, instructions from the Global Note holder or the
Depositary for all purposes.

<PAGE>   47
 
                              PLAN OF DISTRIBUTION
 
     There has previously been only a limited secondary market and no public
market for the Old Notes. The Company does not intend to apply for the listing
of the Senior Notes on a national securities exchange or for their quotation
through The Nasdaq Stock Market. The Old Notes are eligible for trading in the
PORTAL market. The Company has been advised by the Initial Purchasers that the
Initial Purchasers currently intend to make a market in the Senior Notes;
however, no Initial Purchaser is obligated to do so and any market making may be
discontinued by any Initial Purchaser at any time. In addition, such market
making activity may be limited during the Exchange Offer. Therefore, there can
be no assurance that an active market for the Old Notes or the New Notes will
develop.
 
     If a trading market develops for the Old Notes or the New Notes, future
trading prices of such securities will depend on many factors, including, among
other things, prevailing interest rates, the Company's results of operations and
the market for similar securities. Depending on such factors, such securities
may trade at a discount from their offering price.
 
     With respect to resale of New Notes, based on an interpretation by the
staff of the Commission set forth in no-action letters issued to third parties,
the Company believes that a holder (other than a person that is an affiliate of
the Company within the meaning of Rule 405 under the Securities Act or a
"broker" or "dealer" registered under the Exchange Act) who exchanges Old Notes
for New Notes in the ordinary course of business and who is not participating,
does not intend to participate, and has no arrangement or understanding with any
person to participate, in the distribution of the New Notes, will be allowed to
resell the New Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the New Notes a
prospectus that satisfies the requirements of Section 10 thereof. However, if
any holder acquires New Notes in the Exchange Offer for the purpose of
distributing or participating in a distribution of the New Notes, such holder
cannot rely on the position of the staff of the Commission enunciated in Exxon
Capital Holdings Corporation (available May 13, 1988) or similar no-action
letters or any similar interpretive letters and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction, unless an exemption from
registration is otherwise available.
 
     As contemplated by the above no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) the New Notes are to be
acquired by the holder in the ordinary course of business, (ii) the holder is
not engaging and does not intend to engage in the distribution of the New Notes,
and (iii) the holder acknowledges that if such holder participates in the New
Offer for the purpose of distributing the New Notes such holder must comply with
the registration and prospectus delivery requirements of the Securities Act and
cannot rely on the above no-action letters.
 
     Any broker or dealer registered under the Exchange Act (each a
"Broker-Dealer") who holds Old Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company) may exchange such Old Notes for New
Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed
an underwriter within the meaning of the Securities Act and, therefore, must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of the New Notes received by it in the Exchange
Offer, which prospectus delivery requirement may be satisfied by the delivery by
such Broker-Dealer of this Prospectus. The Company and the Subsidiary Guarantors
have agreed to cause the Exchange Offer Registration Statement, of which this
Prospectus is a part, to remain continuously effective for a period of one year
from the date it is first declared effective, and to make this Prospectus, as
amended or supplemented, available to any such Broker-Dealer for use in
connection with resales. Any Broker-Dealer participating in the Exchange Offer
will be required to acknowledge that it will deliver a prospectus in connection
with any resales of New Notes received by it in the Exchange Offer. The delivery
by a Broker-Dealer of a prospectus in connection with resales of New Notes shall
not be deemed to be an admission by such Broker-Dealer that it is an underwriter
within the meaning of the Securities Act. The Company will not receive any
proceeds from any sale of New Notes by a Broker-Dealer.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of Chesapeake Energy Corporation
 
     We have audited the accompanying consolidated balance sheet of Chesapeake
Energy Corporation and its subsidiaries as of June 30, 1996, and the related
consolidated statements of income, stockholders' equity and cash flows for the
year then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Chesapeake
Energy Corporation and its subsidiaries as of June 30, 1996, and the
consolidated results of their operations and their cash flows for the year then
ended in conformity with generally accepted accounting principles.

SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES:
 
     The Company has a financing arrangement with a vendor to supply certain oil
and gas equipment inventory. The total amounts owed at June 30, 1996, 1995 and
1994 were $3,156,000, $6,513,000 and $5,952,000, respectively. No cash
consideration is exchanged for inventory under this financing arrangement until
actual draws on the inventory are made.
 
     In fiscal 1996 and 1995, the Company recognized income tax benefits of
$7,950,000 and $1,229,000, respectively, related to the disposition of stock
options by directors and employees of the Company. The tax benefits were
recorded as an adjustment to deferred income taxes and paid-in capital.
 
     Proceeds from the issuances of $90 million of 10.5% Senior Notes in May
1995 and $120 million of 9.125% Senior Notes in April 1996 are net of $2.7
million and $3.9 million, respectively, in offering fees and expenses which were
deducted from the actual cash received.
 
     On March 31, 1994, the Company issued 8,000 units (see Note 2) to Trust
Company of the West ("TCW") primarily in consideration for the surrender of
576,923 shares of the Company's 9% convertible preferred stock, including its
rights to dividends, warrants to purchase Common Stock and an overriding royalty
interest.
 
     In February 1994, pending litigation was settled pursuant to an agreement
requiring COI to pay $1.25 million, of which $250,000 plus interest was paid in
July 1994, and the balance of which was paid in June 1995.
 
     The accompanying notes are an integral part of these consolidated financial
statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements of Chesapeake Energy
Corporation (the "Company" or "Parent") include the accounts of Chesapeake
Operating, Inc. ("COI"), Chesapeake Exploration Limited Partnership ("CEX"), a
limited partnership, Chesapeake Gas Development Corporation ("CGDC"), Chesapeake
Energy Marketing, Inc. ("CEMI"), Lindsay Oil Field Supply, Inc. ("LOF"), Sander
Trucking Company, Inc. ("STCO") and subsidiaries of those entities. All
significant intercompany accounts and transactions have been eliminated.
 
     In December 1995, the Company entered into the gas marketing business by
acquiring all of the outstanding stock of an Oklahoma City-based natural gas
marketing company for total consideration of $725,000. This subsidiary was
subsequently named CEMI. CEMI provides natural gas marketing services including
commodity price structuring, contract administration and nomination services for
the Company, its partners and other natural gas producers in the geographical
areas in which the Company is active.
 
  Accounting Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
 
  Cash Equivalents
 
     For purposes of the consolidated financial statements, the Company
considers investments in all highly liquid debt instruments with maturities of
three months or less at date of purchase to be cash equivalents.
 
  Inventory
 
     Inventory consists primarily of tubular goods and other lease and well
equipment which the Company plans to utilize in its ongoing exploration and
development activities and is carried at the lower of cost or market using the
specific identification method.
 
  Oil and Gas Properties
 
     The Company follows the full cost method of accounting under which all
costs associated with property acquisition, exploration and development
activities are capitalized. The Company capitalizes internal costs that can be
directly identified with its acquisition, exploration and development activities
and does not include any costs related to production, general corporate overhead
or similar activities (see Note 11). Capitalized costs are amortized on a
composite unit-of-production method based on proved oil and gas reserves. The
Company's oil and gas reserves are estimated annually by independent petroleum
engineers. The average composite rates used for depreciation, depletion and
amortization were $0.85, $0.80 and $0.80 per equivalent Mcf in 1996, 1995, and
1994, respectively. Proceeds from the sale of properties are accounted for as
reductions to capitalized costs unless such sales involve a significant change
in the relationship between costs and the value of proved reserves or the
underlying value of unproved properties, in which case a gain or loss is
recognized. Unamortized costs as reduced by related deferred taxes are subject
to a ceiling which limits such amounts to the estimated present value of oil and
gas reserves, reduced by operating expenses, future development costs and income
taxes. The costs of unproved properties are excluded from amortization until the
properties are evaluated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     On April 30, 1996, the Company purchased interests in certain producing and
non-producing oil and gas properties, including approximately 14,000 net acres
of unevaluated leasehold from Amerada Hess Corporation for $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
  Other Property and Equipment
 
     Other property and equipment primarily consists of vehicles, office
buildings and equipment, and software. Major renewals and betterments are
capitalized while the costs of repairs and maintenance are charged to expense as
incurred. The costs of assets retired or otherwise disposed of and the
applicable accumulated depreciation are removed from the accounts, and the
resulting gain or loss is reflected in operations. Other property and equipment
costs are depreciated on both straight-line and accelerated methods over the
estimated useful lives of the assets, which range from three to 30 years.
 
  Leases
 
     Included in other property and equipment in the consolidated balance sheets
is computer equipment and software held under capital leases. Minimum lease
payments under these capital leases and other operating leases are as follows:

  Capitalized Interest
 
     During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000,
$1,574,000 and $356,000 was capitalized on significant investments in unproved
properties that are not being currently depreciated, depleted, or amortized and
on which exploration or development activities are in progress.
 
  Service Operations
 
     Certain subsidiaries of the Company performed contractual services on wells
the Company operates as well as for third parties until June 30, 1996. Oil and
gas service operations revenues and costs and expenses reflected in the
accompanying consolidated statements of income include amounts derived from
certain of the contractual services provided. The Company's economic interest in
its oil and gas properties is not affected by the performance of these
contractual services and all intercompany profits have been eliminated.
 
     On June 30, 1996, Peak USA Energy Services, Ltd., a limited partnership
("Peak"), was formed by Peak Oilfield Services Company (a joint venture between
Cook Inlet Region, Inc. and Nabors Industries, Inc.) and Chesapeake for the
purpose of purchasing the Company's oilfield service assets and providing rig
moving, transportation and related site construction services to the Company and
the industry. The Company sold its

                 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
service company assets to Peak for $6.4 million, and simultaneously invested
$2.5 million in exchange for a 33.3% partnership interest in Peak. This
transaction resulted in recognition of a $1.8 million pre-tax gain during the
fourth fiscal quarter of 1996 reported in Interest and other. A deferred gain
from the sale of service company assets of $0.9 million was recorded as a
reduction in the Company's investment in Peak and will be amortized to income
over the estimated useful lives of the Peak assets. The Company's investment in
Peak will be accounted for using the equity method.
 
  Income Taxes
 
     The Company has adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes" ("SFAS 109"). SFAS 109 requires deferred tax
liabilities or assets to be recognized for the anticipated future tax effects of
temporary differences that arise as a result of the differences in the carrying
amounts and the tax bases of assets and liabilities.
 
  Net Income Per Share
 
     Primary and fully diluted earnings per share for all periods have been
computed based upon the weighted average number of shares of Common Stock
outstanding after giving retroactive effect to all stock splits and the issuance
of common stock equivalents when their effect is dilutive. Dilutive options or
warrants which are issued during a period or which expire or are cancelled
during a period are reflected in both primary and fully diluted earnings per
share computations for the time they were outstanding during the period being
reported upon.
 
  Gas Imbalances
 
     The Company follows the "sales method" of accounting for its oil and gas
revenue whereby the Company recognizes sales revenue on all oil or gas sold to
its purchasers, regardless of whether the sales are proportionate to the
Company's ownership in the property. A liability is recognized only to the
extent that the Company has a net imbalance in excess of the reserves on the
underlying properties. The Company's net imbalance positions at June 30, 1996
and 1995 were not material.
 
  Hedging
 
     The Company periodically uses certain instruments to hedge its exposure to
price fluctuations on oil and natural gas transactions. Recognized gains and
losses on hedge contracts are reported as a component of the related
transaction. Results for hedging transactions are reflected in oil and gas sales
to the extent related to the Company's oil and gas production.
 
  Debt Issue Costs
 
     Other assets relate primarily to debt issue costs associated with the
issuance of the 12% Senior Notes on March 31, 1994, the 10.5% Senior Notes on
May 25, 1995, and the 9.125% Senior Notes on April 9, 1996 (see Note 2). The
remaining unamortized costs on these issuances of Senior Notes at June 30, 1996
totaled $8.7 million and are being amortized over the life of the Senior Notes.
 
  Stock Options
 
     In October 1995, the Financial Accounting Standards Board issued Statement
No. 123 ("SFAS 123"), "Accounting for Stock Based Compensation". As permitted by
SFAS 123, the Company plans to continue to retain its current method of
accounting for stock compensation and adopt the disclosure requirements of this
Statement in fiscal 1997.

  Reclassifications
 
     Certain reclassifications have been made to the consolidated financial
statements for the years ended June 30, 1995 and 1994 to conform to the
presentation used for the June 30, 1996 consolidated financial statements.
 
2. SENIOR NOTES
 
     On April 9, 1996, the Company completed an offering of $120 million
principal amount of 9.125% Senior Notes due 2006 ("9.125% Senior Notes"). The
9.125% Senior Notes are redeemable at the option of the Company at any time at
the redemption or make-whole prices set forth in the indenture. The Company may
also redeem at its option at any time on or prior to April 15, 1999 up to $42
million of the 9.125% Senior Notes at 109.125% of the principal amount thereof
with the proceeds of an equity offering.
 
     On May 25, 1995, the Company completed a private offering of $90 million
principal amount of 10.5% Senior Notes due 2002 ("10.5% Senior Notes"). The
10.5% Senior Notes are redeemable at the option of the Company at any time on or
after June 1, 1999. The Company may also redeem at its option any time prior to
June 1, 1998 up to $30 million of the 10.5% Senior Notes at 110% of the
principal amount thereof with the proceeds of an equity offering. In September
1995, the Company exchanged the 10.5% Senior Notes for substantially identical
notes in a registered exchange offer (also referred to as the "10.5% Senior
Notes").
 
     On March 31, 1994, the Company completed a private offering of 47,500 Units
consisting of an aggregate of $47.5 million principal amount of 12% Senior Notes
due 2001 ("12% Senior Notes") and warrants ("Warrants") to purchase 4,381,874
shares of the Company's Common Stock at an aggregate exercise price of $4,870.
The Warrants were valued at $3 million creating a discount on the 12% Senior
Notes. All of the Warrants were subsequently exercised. In exchange for 8,000
Units, the Company acquired from Trust Company of the West ("TCW") 576,923
shares of the Company's 9% cumulative convertible preferred stock and all rights
to dividends thereon, warrants to purchase 2,808,008 shares of the Company's
Common Stock and 50% of an outstanding overriding royalty interest held by TCW.
The 12% Senior Notes are redeemable at the option of the Company at any time on
or after March 1, 1998 at an initial premium of 106% of the principal amount
thereof, declining to no premium in 2000. The Company is required to redeem
$11,875,000 principal amount of 12% Senior Notes on each of March 1, 1998, 1999
and 2000. In November 1994, the Company exchanged the 12% Senior Notes for
substantially identical notes in a registered exchange offer (also referred to
as the "12% Senior Notes").
 
     The Company is a holding company and owns no operating assets and has no
significant operations independent of its subsidiaries. The Company's
obligations under the 12% Senior Notes, the 10.5% Senior Notes and the 9.125%
Senior Notes have been fully and unconditionally guaranteed, on a joint and
several basis, by each of the Company's "Restricted Subsidiaries" (as defined in
the respective Indentures governing the Notes): COI, LOF, STCO, Whitmire Dozer
Service, Inc. and CEX (collectively, the "Subsidiary Guarantors"). The only
subsidiaries of the Company that are not Subsidiary Guarantors are CGDC and CEMI
(together, the "Non-Guarantor Subsidiaries"). Each of the Subsidiary Guarantors
is a direct or indirect wholly-owned subsidiary of the Company. The securities
of the Subsidiary Guarantors have been pledged to secure performance of the
Company's obligations under the 12% Senior Notes. The only affiliate securities
constituting a substantial portion of the collateral for the 12% Senior Notes
are the partnership interests in CEX.
 
     The 12%, 10.5% and 9.125% Senior Note Indentures contain certain covenants,
including covenants limiting the Company and the Subsidiary Guarantors with
respect to asset sales; restricted payments; the incurrence of additional
indebtedness and the issuance of preferred stock; liens; sale and leaseback
transactions; lines of business; dividend and other payment restrictions
affecting Subsidiary Guarantors; mergers or consolidations; and transactions
with affiliates. The Company is also obligated to repurchase 12%,

10.5% and 9.125% Senior Notes if it fails to maintain a specified ratio of
assets to debt and in the event of a change of control or certain asset sales.
 
     The Company's bank credit agreement prohibits any distributions by CEX to
its partners (the Company and COI) if the maturity of any obligations to the
lender has been accelerated. The pledge agreement relating to the 12% Senior
Notes requires that all dividends and distributions from Subsidiary Guarantors
be paid to the collateral agent thereunder upon an event of default under the
12% Senior Notes Indenture. There are no other restrictions on the payment of
cash dividends by Subsidiary Guarantors.
 
     CEX is a limited partnership which is 10% owned by COI, as sole general
partner, and 90% owned directly by the Company, as sole limited partner. CEX
owns 94% and CGDC owns 6% of the Company's producing oil and gas properties,
based on the present value of future net revenue at June 30, 1996 (discounted at
10%).
 
     Set forth below are condensed consolidating financial statements of CEX,
the other Subsidiary Guarantors, all Subsidiary Guarantors combined, the
Non-Guarantor Subsidiaries and the Company. The CEX limited partnership
condensed financial statements were prepared on a separate entity basis as
reflected in the Company's books and records and include all material costs of
doing business as if the partnership were on a stand-alone basis except that
interest is not charged or allocated. No provision has been made for income
taxes because the partnership is not a taxpaying entity. Separate audited
financial statements of each Subsidiary Guarantor, other than CEX, have not been
provided because management has determined that they are not material to
investors.

     In April 1993, CEX entered into an oil and gas reserve-based reducing
revolving credit facility (the "Revolving Credit Facility") with Union Bank. The
Revolving Credit Facility has been amended from time to

time, most recently in September 1996. Concurrent with the September 1996
amendment, the Company increased the facility size to $125 million and expanded
its bank group with Union Bank remaining as agent.
 
     The maturity date of the Revolving Credit Facility is April 30, 2001. The
facility provides for interest at the Union Bank reference rate (8.25% at June
30, 1996) or, at the option of the Company the Eurodollar rate plus 1.375% to
1.875% depending on the ratio of the amount outstanding to the borrowing base.
Borrowings are collateralized by a first priority lien on substantially all of
CEX's proved producing reserves, and are unconditionally guaranteed by the
Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under
the Revolving Credit Facility, respectively.
 
     The amount of credit available at any time under the Revolving Credit
Facility is the lesser of the commitment amount or the borrowing base. The
borrowing base is reduced each month by a specified amount. Both the borrowing
base and the monthly reduction amount are redetermined by Union Bank each May 1
and November 1 and may be redetermined at any other time upon the request of CEX
or Union Bank. To the extent the amount outstanding at any time exceeds the
borrowing base, CEX must reduce the amount outstanding or add additional
collateral. At June 30, 1996, the commitment amount and the borrowing base under
the Revolving Credit Facility were $35 million, and the monthly reduction amount
was $700,000. The Revolving Credit Facility was amended in September 1996 to
provide for a borrowing base and a commitment amount of $75 million, with a
monthly reduction amount of $1,750,000. The Revolving Credit Facility contains
customary financial covenants, limitations on indebtedness and liabilities,
liens, prepayments of other indebtedness (including the 12%, 10.5% and 9.125%
Senior Notes) and loans, investments and guarantees by the Company and prohibits
the payment of dividends on the Company's Common Stock.
 
     The Company's wholly-owned subsidiary, CGDC, has a credit facility with
Union Bank (the "Term Credit Facility"), with an outstanding balance of $12.9
million at June 30, 1996. Collateral for the Term Credit Facility is limited to
CGDC's producing oil and gas properties. The Term Credit Facility has not been
guaranteed by the Company or any of its other subsidiaries and is recourse only
to the assets of CGDC. CGDC acquired producing oil and gas properties from CEX
in December 1994, June 1995 and December 1995 in exchange for $5.5 million, $6
million and $5.3 million in cash, respectively, using proceeds borrowed under
this facility. CGDC has not guaranteed the payment of the Company's 12%, 10.5%
or 9.125% Senior Notes, nor has the capital stock of CGDC been pledged as
collateral for such indebtedness. The terms of the Term Credit Facility prohibit
the payment of dividends by CGDC.
 
4. CONTINGENCIES AND COMMITMENTS
 
     The Company is currently involved in various routine disputes incidental to
its business operations. While it is not possible to determine the ultimate
disposition of these matters, management, after consultation with legal counsel,
is of the opinion that the final resolution of all currently pending or
threatened litigation is not likely to have a material adverse effect on the
consolidated financial position or results of operations of the Company.
 
     The Company has employment contracts with its two principal shareholders
and its chief financial officer and various other senior management personnel
which provide for annual base salaries, bonus compensation and various benefits.
The contracts provide for the continuation of salary and benefits for the
respective terms of the agreements in the event of termination of employment
without cause. These agreements expire June 30, 1997 through June 30, 1998.
 
     Due to the nature of the oil and gas business, the Company and its
subsidiaries are exposed to possible environmental risks. The Company has
implemented various policies and procedures to avoid environmental contamination
and risks from environmental contamination. The Company is not aware of any
potential environmental issues or claims.

     At June 30, 1996, the Company had regular tax net operating loss
carryforwards of approximately $140 million and alternative minimum tax net
operating loss carryforwards of approximately $15 million. These loss
carryforward amounts will expire during the years 2007 through 2011. The Company
also had a percentage depletion carryforward of approximately $2.3 million at
June 30, 1996, which is available to offset future federal income taxes payable
and has no expiration date.
 
     In accordance with certain provisions of the Tax Reform Act of 1986, a
change of greater than 50% of the beneficial ownership of the Company within a
three-year period (an "Ownership Change") would place an annual limitation on
the Company's ability to utilize its existing tax carryforwards. Under

the Internal Revenue Service, the Company does not believe that an Ownership
Change has occurred as of June 30, 1996.
 
6. RELATED PARTY TRANSACTIONS
 
     Certain directors, shareholders and employees of the Company have acquired
working interests in certain of the Company's oil and gas properties. The owners
of such working interests are required to pay their proportionate share of all
costs. As of June 30, 1996, 1995 and 1994 the Company had accounts receivable
for these costs of $2.9 million, $4.4 million and $1.7 million, respectively.
 
     During fiscal 1996, 1995 and 1994 the Company incurred legal expenses of
$347,000, $516,000 and $631,000, respectively, for legal services provided by
the law firm of which a director is a member.
 
7. EMPLOYEE BENEFIT PLANS
 
     Effective October 1, 1989, the Company established a 401(K) profit sharing
plan. On December 1, 1993, the Company amended the plan and established the
Chesapeake Energy Savings and Incentive Plan. On January 1, 1996 the Company
amended the plan and established the Chesapeake Energy Corporation Savings and
Incentive Stock Bonus Plan (the "Savings and Incentive Stock Bonus Plan").
Eligible employees may make voluntary contributions to the Savings and Incentive
Stock Bonus Plan which are matched by the Company up to 10% of the employees'
annual salary with the Company's common stock. The amount of employee
contributions is limited as specified in the Savings and Incentive Stock Bonus
Plan. The Company may, at its discretion, make additional contributions to the
Savings and Incentive Stock Bonus Plan. The Company contributed $187,000,
$95,000 and $70,000 to the Savings and Incentive Stock Bonus Plan during the
fiscal years ended June 30, 1996, 1995 and 1994, respectively.

9. STOCKHOLDERS' EQUITY
 
     Effective December 31, 1996, the Company changed its state of incorporation
from Delaware to Oklahoma. As part of this transaction, the authorized capital
stock of the Company was increased to 100,000,000 shares of common stock, par
value $.01 per share, and 10,000,000 shares of preferred stock, par

value $.01 per share. Also effective December 31, 1996, the Company effected a
2-for-1 split of its common stock. All par value, share and per share
information, common stock options and exercise prices included in these
consolidated financial statements and related footnotes have been restated to
reflect the stock split.
 
     On April 9, 1996, the Company completed a public offering of 4,950,000
shares of Common Stock at a price of $17.67 per share, resulting in net proceeds
(after offering costs) to the Company of approximately $82.1 million. On April
12, 1996, the underwriters exercised an over-allotment option to purchase an
additional 1,039,500 shares of Common Stock at a price of $17.67 per share,
resulting in additional net proceeds (after offering costs) to the Company of
approximately $17.3 million. The net proceeds from the offering were used to
fund a portion of the Company's exploration and development capital expenditures
and for general corporate purposes.
 
     On March 31, 1994, the Company issued 12% Senior Notes and Warrants for
4,381,874 shares of the Company's Common Stock (see Note 2). The Warrants were
valued at $3.04 million and are recorded as Common Stock Warrants and paid-in
capital on the accompanying consolidated balance sheets. A portion of the 12%
Senior Notes and Warrants were issued to Trust Company of the West in exchange
for preferred stock, warrants to purchase Common Stock and an overriding royalty
interest.
 
     A 1.8-for-1 stock split of the Common Stock in January 1993, a 2-for-1
stock split of the Common Stock in December 1994, and 3-for-2 stock splits of
the Common Stock in December 1995 and June 1996 have been given retroactive
effect in these financial statements.
 
  Stock Option Plans
 
     Under the Company's 1992 Incentive Stock Option Plan (the "ISO Plan"),

3,132,000 shares. The maximum period for exercise of an option may not be more
than ten years from the date of grant, and the exercise price may not be less
than the fair market value of the shares underlying the options on the date of
grant. Options granted become exercisable at dates determined by the Stock

     The exercise of certain stock options results in state and federal income
tax benefits to the Company related to the difference between the market price
of the Common Stock at the date of disposition (or sale) and the option price.
During fiscal 1996 and 1995, $7,950,000 and $1,229,000 was recorded as an
adjustment to additional paid-in capital and deferred income taxes with respect
to such tax benefits.
 
10. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
 
     The Company has only limited involvement with derivative financial
instruments, as defined in Statement of Financial Accounting Standards No. 119
"Disclosure About Derivative Financial Instruments and Fair Value of Financial
Instruments" and does not use them for trading purposes. The Company's objective
is to hedge a portion of its exposure to price volatility from producing crude
oil and natural gas. These arrangements may expose the Company to credit risk
from its counter-parties and to basis risk.
 
 Hedging Activities
 
     Periodically the Company utilizes hedging strategies to hedge the price of
a portion of its future oil and gas production. These strategies include swap
arrangements that establish an index-related price above which the Company pays
the hedging partner and below which the Company is paid by the hedging partner,
the purchase of index-related puts that provide for a "floor" price to the
Company to be paid by the counter-party to the extent the price of the commodity
is below the contracted floor, and basis protection swaps.
 
     As of June 30, 1996, the Company had established NYMEX-based crude oil swap
agreements for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an
average price of $17.85 per Bbl. The counter-party has the option exercisable
monthly for an additional 1,000 Bbl per day for the period July 1, 1996 through
December 31, 1996 to cause a swap if the price exceeds an average $17.74 per
Bbl. The actual settlements for July and August resulted in a $0.5 million
payment to the counter-party. The Company estimates, based on NYMEX prices as of
August 30, 1996, that the effect of the September through December hedges would
be a $0.4 million payment to the counter-party.
 
     The Company has purchased Houston Ship Channel put options which guarantee
the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for
the period of November 1, 1996 through February 28, 1997. The average cost of
these puts was $0.14 per Mmbtu.
 
     As of June 30, 1996, the Company had NYMEX-based natural gas swaps and
NYMEX/Houston Ship Channel Basis swaps for the months of July through October
1996. These transactions resulted in payments to

                 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the Company's counter-party of approximately $2 million for the month of July
1996 and $1.5 million for the month of August 1996. The Company estimates, based
on NYMEX prices as of August 30, 1996, that the effect of the September and
October hedges would be a $0.2 million payment to the counter-party.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of trade receivables. The
Company's accounts receivable are primarily from purchasers of oil and natural
gas products and exploration and production companies which own interests in
properties operated by the Company. The industry concentration has the potential
to impact the Company's overall exposure to credit risk, either positively or
negatively, in that the customers may be similarly affected by changes in
economic, industry or other conditions. The Company generally requires letters
of credit for receivables from customers which are not considered investment
grade, unless the credit risk can otherwise be mitigated.
 
  Fair Value of Financial Instruments
 
     The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of Statement of
Financial Accounting Standards No. 107, "Disclosures About Fair Value of
Financial Instruments." The estimated fair value amounts have been determined by
the Company using available market information and valuation methodologies.
Considerable judgment is required in interpreting market data to develop the
estimates of fair value. The use of different market assumptions or valuation
methodologies may have a material effect on the estimated fair value amounts.
 
     The carrying values of items comprising current assets and current
liabilities approximate fair values due to the short-term maturities of these
instruments. The Company estimates the fair value of its long-term, fixed-rate
debt using quoted market prices. The Company's carrying amount for such debt at
June 30, 1996 and 1995 was $255.6 million and $135.2 million, respectively,
compared to approximate fair values of $261.2 million and $137.8 million,
respectively. The carrying value of other long-term debt approximates its fair
value as interest rates are primarily variable, based on prevailing market
rates.

     Unproved properties not subject to amortization at June 30, 1996 and 1995,
consist mainly of lease acquisition costs. The Company capitalized approximately
$6,428,000 and $1,574,000 of interest during the years ended June 30, 1996 and
1995 on significant investments in unproved properties that are not being
currently depreciated, depleted, or amortized and on which exploration or
development activities are in progress. The Company will continue to evaluate
its unevaluated properties; however, the timing of the ultimate evaluation and
disposition of the properties has not been determined.

  Oil and Gas Reserve Quantities (unaudited)
 
     The reserve information presented below is based upon reports prepared by
the independent petroleum engineering firm of Williamson Petroleum Consultants,
Inc. ("Williamson") as of June 30, 1996, 1995 and 1994 and the Company's
petroleum engineers as of June 30, 1996 and 1995. The reserves evaluated
internally by the Company constituted approximately 0.6% and 0.5% of total
proved reserves as of June 30, 1996 and 1995, respectively. The information is
presented in accordance with regulations prescribed by the Securities and
Exchange Commission. The Company emphasizes that reserve estimates are
inherently imprecise. The Company's reserve estimates were generally based upon
extrapolation of historical production trends, analogy

to similar properties and volumetric calculations. Accordingly, these estimates
are expected to change, and such changes could be material, as future
information becomes available.
 
     Proved oil and gas reserves represent the estimated quantities of crude
oil, natural gas, and natural gas liquids which geological and engineering data
demonstrate with reasonable certainty to be recoverable in future years from
known reservoirs under existing economic and operating conditions. Proved
developed oil and gas reserves are those expected to be recovered through
existing wells with existing equipment and operating methods.
 
     Presented below is a summary of changes in estimated reserves of the
Company based upon the reports prepared by Williamson for 1996, 1995 and 1994,
along with those prepared by the Company's petroleum engineers for 1996 and
1995:

     On April 30, 1996, the Company purchased interests in certain producing and
non-producing oil and gas properties, including approximately 14,000 net acres
of unevaluated leasehold, from Amerada Hess Corporation for $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
     In October 1993, the Company entered into a joint development agreement
covering a 20,000 gross acre development area in the Fayette County portion of
the Giddings Field in southern Texas. The Company's ownership interests in the
proved undeveloped properties covered by the joint development agreement were
significantly less than those used in the June 30, 1993 reserve report. The
impact of the reduced ownership percentages is reflected as sales of reserves in
place in fiscal 1994 in the preceding table.
 
  Standardized Measure of Discounted Future Net Cash Flows (unaudited)
 
     Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes
guidelines for computing a standardized measure of future net cash flows and
changes therein relating to estimated proved reserves. The Company has followed
these guidelines which are briefly discussed below.
 
     Future cash inflows and future production and development costs are
determined by applying year-end prices and costs to the estimated quantities of
oil and gas to be produced. Estimates are made of quantities of proved reserves
and the future periods during which they are expected to be produced based on
year-end economic conditions. Estimated future income taxes are computed using
current statutory income tax rates including consideration for the current tax
basis of the properties and related carryforwards, giving effect to

permanent differences and tax credits. The resulting future net cash flows are
reduced to present value amounts by applying a 10% annual discount factor.
 
     The assumptions used to compute the standardized measure are those
prescribed by the Financial Accounting Standards Board and, as such, do not
necessarily reflect the Company's expectations of actual revenue to be derived
from those reserves nor their present worth. The limitations inherent in the
reserve quantity estimation process, as discussed previously, are equally
applicable to the standardized measure computations since these estimates are
the basis for the valuation process.
 
     The following summary sets forth the Company's future net cash flows
relating to proved oil and gas reserves based on the standardized measure
prescribed in SFAS 69:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the General Partner and Limited Partner of
Chesapeake Exploration Limited Partnership
 
     We have audited the accompanying balance sheet of Chesapeake Exploration
Limited Partnership ("CEX") as of June 30, 1996, and the related consolidated
statements of income, partners' capital and cash flows for the year then ended.
These financial statements are the responsibility of the CEX management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of CEX as of June 30, 1996, and
the results of its operations and its cash flows for the year then ended in
conformity with generally accepted accounting principles.
 
     As more fully described in Note 1, CEX is a limited partnership owned by
Chesapeake Energy Corporation ("CEC") and Chesapeake Operating, Inc. ("COI").
CEX has no employees and it is dependent on the financial resources of CEC and
COI as well as being dependent on management by COI. Accordingly, CEX has
significant transactions with CEC and COI which are disclosed in Note 4. The
financial statements of CEX should be read in conjunction with the consolidated
financial statements of CEC.

its operations and its cash flows for each of the two years in the period then
ended, in conformity with generally accepted accounting principles. These

believe that our audits provide a reasonable basis for the opinion expressed
above. We have not audited the financial statements of CEX for any period
subsequent to June 30, 1995.

SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES:
 
     During the three years ended June 30, 1996, CEX had non-cash intercompany
transactions with the Company consisting primarily of allocated general and
administrative expenses. In fiscal 1996 and 1995, the difference between the net
book value and the proceeds from the sale of oil and gas properties sold to CGDC
of $782,000 and $2,852,000, respectively, resulted in a non-cash transfer.
 
  The accompanying notes are an integral part of these consolidated financial
                                  statements.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Chesapeake Exploration Limited Partnership, an Oklahoma limited partnership
("CEX"), was formed on December 27, 1994 and acquired Chesapeake Exploration
Company ("Exploration") by merger on such date. Exploration was a general
partnership which was 10% owned by Chesapeake Operating, Inc. ("COI") and 90%
owned by Chesapeake Energy Corporation ("CEC" or the "Company"). CEC owns 100%
of the Common Stock of COI. CEX is 10% owned by COI as the sole general partner,
and 90% owned directly by the Company, as the sole limited partner.
 
     Effective December 31, 1994, COI transferred to CEX all of the Company's
undeveloped leasehold acreage, thereby formalizing their prior economic
arrangement. Historically, COI had transferred undeveloped leasehold acreage to
CEX on a property-by-property basis as drilling commenced. CEX also owns
substantially all of the Company's proved developed oil and gas properties.
Accordingly, the financial statements of CEX include costs related to proved
undeveloped properties and unevaluated properties, as well as proved producing
properties. The change in partnership structure and the transfer of undeveloped
leasehold by COI to CEX have been accounted for as a reorganization of entities
under common control in a manner similar to a pooling-of-interests.
 
     The CEX financial statements were prepared on a separate entity basis as
reflected in the Company's books and records and include all material costs of
doing business as if the partnership were on a stand-alone basis, except that
interest is not charged on intercompany accounts, or allocated.
 
     Capital is provided by advances from CEC and COI, and to a lesser extent
directly by CEX's bank credit facilities.
 
     These financial statements should be read in conjunction with CEC's
consolidated financial statements.
 
  Accounting Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
  Oil and Gas Properties
 
     CEC, and therefore CEX, follows the full cost method of accounting under
which all costs associated with property acquisition, exploration and
development activities are capitalized. CEX capitalizes internal costs that can
be directly identified with its acquisition, exploration and development
activities. Such costs do not include any costs related to production, general
corporate overhead or similar activities (see Note 7). Capitalized costs are
amortized on a composite unit-of-production method based on proved oil and gas
reserves. CEX's oil and gas reserves are estimated annually by independent
petroleum engineers. The average composite rates used for depreciation,
depletion and amortization were $.85, $.80 and $.80 per equivalent Mcf in 1996,
1995 and 1994, respectively. Proceeds from the sale of properties are accounted
for as reductions to capitalized costs unless such sales involve a significant
change in the relationship between costs and the value of proved reserves or the
underlying value of unproved properties, in which case a gain or loss is
recognized. Unamortized costs, as reduced by related deferred taxes, are subject
to a ceiling which limits such amounts to the estimated present value of oil and
gas reserves, reduced by operating expenses, future development costs and income
taxes. The costs of unproved properties are excluded from amortization until the
properties are evaluated.

         (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     On April 30, 1996, CEX purchased interests in certain producing and
non-producing oil and gas properties, including approximately 14,000 net acres
of unevaluated leasehold, from Amerada Hess Corporation for $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
  Capitalized Interest
 
     During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000,
$1,574,000 and $356,000 was capitalized on significant investments in unproved
properties that are not being currently depreciated, depleted, or amortized and
on which exploration or development activities are in progress.
 
  Intercompany Transactions
 
     COI, as operator of the majority of CEX's producing properties, bills CEX,
as non-operator, on a monthly basis for services performed as operator pursuant
to a standard operating agreement which is common in the industry. Expenses
related to the operations of CEX are recorded via such joint interest billings
and via intercompany expense allocations to CEX by COI. CEX has no employees. In
the CEC consolidated group, COI employs all management personnel and employees,
except for employees of the service company subsidiaries, and the preponderance
of general and administrative expenses are reflected in the financial records of
COI. COI allocates a portion of its general and administrative expenses to CEX
each period. This allocation is based on a per well charge at a rate common in
the industry plus an estimate of time spent on CEX activities by officers and
employees of COI.
 
     CEC makes advances to CEX as needed. Certain of CEC's service subsidiaries
perform contractual services on CEX's wells for third parties. These
subsidiaries bill COI, as operator, and COI in turn bills CEX through monthly
joint interest billings in accordance with the terms of the standard operating
agreement.
 
     It is CEC's policy not to demand payment of intercompany accounts. Interest
is not allocated by the Company, nor is interest charged on intercompany
accounts. CEC may, at its discretion, but it is not required to, contribute
intercompany accounts to capital.
 
  Income Taxes
 
     CEX is a partnership and, accordingly, its taxable income or loss is
allocated to the limited partner and the general partner and is ultimately
included in CEC's consolidated tax returns.
 
  Gas Imbalances
 
     CEX follows the "sales method" of accounting for its oil and gas revenue
whereby CEX recognizes sales revenue on all oil or gas sold to its purchasers,
regardless of whether the sales are proportionate to CEX's ownership in the
property. A liability is recognized only to the extent that CEX has a net
imbalance in excess of the reserves on the underlying properties. CEX's net
imbalance positions at June 30, 1996 and 1995 were not material.
 
  Hedging
 
     The Company, on behalf of CEX, periodically uses certain instruments to
hedge its exposure to price fluctuations on oil and natural gas transactions.
Recognized gains and losses on hedge contracts are reported as a component of
the related transaction. Results for hedging transactions are reflected in oil
and gas sales to the extent related to CEX's oil and gas production.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Reclassifications
 
     Certain reclassifications have been made to the CEX financial statements
for the years ended June 30, 1995 and 1994 to conform to the presentation used
for the June 30, 1996 financial statements.
 
2. LONG-TERM DEBT
 
     In April 1993, CEX entered into an oil and gas reserve-based reducing
revolving credit facility (the "Revolving Credit Facility") with Union Bank. The
Revolving Credit Facility has been amended from time to time, most recently in
September 1996. Concurrent with the September 1996 amendment, CEX increased the
facility size to $125 million and expanded its bank group with Union Bank
remaining as agent.
 
     The maturity date of the Revolving Credit Facility is April 30, 2001. The
facility provides for interest at the Union Bank reference rate (8.25% at June
30, 1996) or, at the option of CEX the Eurodollar rate plus 1.375% to 1.875%
depending on the ratio of the amount outstanding to the borrowing base.
Borrowings are collateralized by a first priority lien on substantially all of
CEX's proved producing reserves, and are unconditionally guaranteed by the
Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under
the Revolving Credit Facility, respectively.
 
     The amount of credit available at any time under the Revolving Credit
Facility is the lesser of the commitment amount or the borrowing base. The
borrowing base is reduced each month by a specified amount. Both the borrowing
base and the monthly reduction amount are redetermined by Union Bank each May 1
and November 1 and may be redetermined at any other time upon the request of CEX
or Union Bank. To the extent the amount outstanding at any time exceeds the
borrowing base, CEX must reduce the amount outstanding or add additional
collateral. At June 30, 1996, the commitment amount and the borrowing base under
the Revolving Credit Facility were $35 million, and the monthly reduction amount
was $700,000. The Revolving Credit Facility was amended in September 1996 to
provide for a borrowing base and a commitment amount of $75 million, with a
monthly reduction amount of $1,750,000. The Revolving Credit Facility contains
customary financial covenants, limitations on indebtedness and liabilities,
liens, prepayments of other indebtedness and loans, investments and guarantees
by the Company and prohibits the payment of dividends on the Company's Common
Stock.
 
3. CONTINGENCIES AND COMMITMENTS
 
     CEX has fully and unconditionally guaranteed CEC's obligations under the
$47.5 million principal amount of 12% Senior Notes due 2001, issued March 31,
1994, the $90 million principal amount of 10.5% Senior Notes due 2002, issued
May 25, 1995, and the $120 million principal amount of 9.125% Senior Notes due
2006, issued April 9, 1996. In addition, the CEX partnership interests have been
pledged as collateral under the 12% Senior Notes.
 
4. RELATED PARTY TRANSACTIONS
 
     CEX has significant transactions with COI, CEC, CGDC and other affiliated
companies included in the CEC consolidated group, including:
 
     COI as operator for CEX:

6. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
 
     The Company, on behalf of CEX, has only limited involvement with derivative
financial instruments, as defined in Statement of Financial Accounting Standards
No. 119 "Disclosure About Derivative Financial Instruments and Fair Value of
Financial Instruments" and does not use them for trading purposes. The Company's
objective is to hedge a portion of its exposure to price volatility from
producing crude oil and natural gas. These arrangements may expose the Company
to credit risk from its counter-parties and to basis risk.
 
  Hedging Activities
 
     Periodically the Company, on behalf of CEX, utilizes hedging strategies to
hedge the price of a portion of its future oil and gas production. These
strategies include swap arrangements that establish an index-related price above
which the Company pays the hedging partner and below which the Company is paid
by the hedging partner, the purchase of index-related puts that provide for a
"floor" price to the Company to be paid by the counter-party to the extent the
price of the commodity is below the contracted floor, and basis protection
swaps.
 
     As of June 30, 1996, the Company had NYMEX-based crude oil swap agreements
for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an average
price of $17.85 per Bbl. The counter-party has the option exercisable monthly
for an additional 1,000 Bbl per day for the period July 1, 1996 through December
31, 1996 to cause a swap if the price exceeds an average $17.74 per Bbl. The
actual settlements for July and August resulted in a $0.5 million payment to the
counter-party. The Company estimates, based on NYMEX prices as of August 30,
1996 that the effect of the September through December hedges would be a $0.4
million payment to the counter-party.
 
     The Company has purchased Houston Ship Channel put options which guarantee
the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for
the period of November 1, 1996 through February 28, 1997. The average cost of
these puts was $0.14 per Mmbtu.
 
     As of June 30, 1996, the Company had NYMEX-based natural gas swaps and
NYMEX/Houston Ship Channel Basis swaps for the months of July through October
1996. These transactions resulted in payments to

the Company's counter-party of approximately $2 million for the month of July
1996 and $1.5 million for the month of August 1996. The Company estimates, based
on NYMEX prices as of August 30, 1996, that the effect of the September and
October hedges would be a $0.2 million payment to the counter-party.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject CEX to concentrations of
credit risk consist principally of trade receivables. CEX's accounts receivable
are primarily from purchasers of oil and natural gas products and exploration
and production companies which own interests in properties operated by the
Company. The industry concentration has the potential to impact CEX's overall
exposure to credit risk, either positively or negatively, in that the customers
may be similarly affected by changes in economic, industry or other conditions.
The Company generally requires letters of credit for receivables from customers
which are not considered investment grade, unless the credit risk can otherwise
be mitigated.
 
  Fair Value of Financial Instruments
 
     The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of Statement of
Financial Accounting Standards No. 107, "Disclosures About Fair Value of
Financial Instruments". The estimated fair value amounts have been determined by
the Company using available market information and valuation methodologies.
Considerable judgment is required in interpreting market data to develop the
estimates of fair value. The use of different market assumptions or valuation
methodologies may have a material effect on the estimated fair value amounts.
 
     The carrying values of items comprising current assets and current
liabilities approximate fair values due to the short-term maturities of these
instruments. Based on the borrowing rates currently available to CEX for bank
loans with similar terms and average maturities, the fair value of long-term
debt approximates the carrying value.

     Unproved properties not subject to amortization at June 30, 1996 and 1995,
consist mainly of lease acquisition costs. CEX capitalized approximately
$6,428,000 and $1,574,000 of interest during the years ended June 30, 1996 and
1995 on significant investments in unproved properties that are not being
currently depreciated, depleted, or amortized and on which exploration or
development activities are in progress. CEX will continue to evaluate its
unevaluated properties; however, the timing of the ultimate evaluation and
disposition of the properties has not been determined.

  Oil and Gas Reserve Quantities (Unaudited)
 
     The reserve information presented below is based upon reports prepared by
the independent petroleum engineering firm of Williamson Petroleum Consultants,
Inc. ("Williamson") as of June 30, 1996, June 30, 1995 and June 30, 1994 and the
Company's petroleum engineers as of June 30, 1996 and 1995. The reserves
evaluated by the Company's petroleum engineers constituted approximately 0.6%
and 0.5% of total proved reserves as of June 30, 1996 and 1995, respectively.
The information is presented in accordance with regulations prescribed by the
Securities and Exchange Commission. CEX emphasizes that reserve estimates are
inherently imprecise. CEX's reserve estimates were generally based upon
extrapolation of historical production trends, analogy to similar properties and
volumetric calculations. Accordingly, these estimates are expected to change,
and such changes could be material, as future information becomes available.
 
     Proved oil and gas reserves represent the estimated quantities of crude
oil, natural gas, and natural gas liquids which geological and engineering data
demonstrate with reasonable certainty to be recoverable in

     On April 30, 1996, the Company purchased interests in certain producing and
non-producing oil and gas properties, including approximately 14,000 net acres
of unevaluated leasehold, from Amerada Hess Corporation for $35 million, subject
to adjustment for activity after the effective date of January 1, 1996. The
properties are located in the Knox and Golden Trend fields of southern Oklahoma,
most of which are operated by the Company.
 
     In October 1993, CEX entered into a joint development agreement covering a
20,000 gross acre development area in the Fayette County portion of the Giddings
Field in southern Texas. CEX's ownership interests in the proved undeveloped
properties covered by the joint development agreement were significantly less
than those used in the June 30, 1993 reserve report. The impact of the reduced
ownership percentages is reflected as sales of reserves in place in fiscal 1994
in the preceding table.
 
  Standardized Measure of Discounted Future Net Cash Flows (Unaudited)
 
     Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes
guidelines for computing a standardized measure of future net cash flows and
changes therein relating to estimated proved reserves. CEX has followed these
guidelines which are briefly discussed below.
 
     Future cash inflows and future production and development costs are
determined by applying year-end prices and costs to the estimated quantities of
oil and gas to be produced. Estimates are made of quantities of proved reserves
and the future periods during which they are expected to be produced based on
year-end economic conditions. Estimated future income taxes are computed using
current statutory income tax rates including consideration for the current tax
basis of the properties and related carryforwards, giving effect to permanent
differences and tax credits. The income tax effect of these future cash inflows
will be recognized by CEX's partners. The resulting future net cash flows are
reduced to present value amounts by applying a 10% annual discount factor.
 
     The assumptions used to compute the standardized measure are those
prescribed by the Financial Accounting Standards Board and, as such, do not
necessarily reflect CEX's expectations of actual revenue to
 
                                      F-42

be derived from those reserves nor their present worth. The limitations inherent
in the reserve quantity estimation process, as discussed previously, are equally
applicable to the standardized measure computations since these estimates are
the basis for the valuation process.

proved oil and gas reserves based on the standardized measure prescribed in SFAS

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
                                  (UNAUDITED)
 
1. ACCOUNTING PRINCIPLES
 
     The accompanying unaudited consolidated financial statements of Chesapeake
Energy Corporation and Subsidiaries (the "Company") have been prepared in
accordance with the instructions to Form 10-Q as prescribed by the Securities
and Exchange Commission. All material adjustments (consisting solely of normal
recurring adjustments) which, in the opinion of management, are necessary for a
fair presentation of the results for the interim periods have been reflected.
The results for the three months and six months ended December 31, 1996, are not
necessarily indicative of the results to be expected for the full fiscal year.
 
2. RECENT EVENTS
 
     On November 25, 1996, the Company issued 8,000,000 shares of Common Stock
in a public offering at a price of $33.63 per share, which resulted in net
proceeds to the Company of approximately $256.9 million. On December 2, 1996,
the underwriters of the Company's Common Stock offering exercised an
over-allotment option to purchase an additional 972,000 shares of Common Stock
at a price of $33.63 per share, resulting in additional net proceeds to the
Company of approximately $31.2 million, and total proceeds of $288.1 million.
 
     Using a portion of the proceeds from the Common Stock offering, the Company
exercised its covenant defeasance rights under Section 8.03 of the Indenture
dated as of March 31, 1994 with respect to all of its outstanding $47.5 million
of 12% Senior Notes. A combination of cash and non-callable U.S. Government
Securities in the amount of $55 million was irrevocably deposited in trust to
satisfy the Company's obligations, including accrued but unpaid interest through
the date of defeasance of $1.3 million. The Company also repaid in full the
outstanding balance of its revolving bank credit facility.
 
     Effective December 31, 1996, the Company changed its state of incorporation
from Delaware to Oklahoma. As part of this transaction, the authorized capital
stock of the Company was increased to 100,000,000 shares of common stock, par
value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01
per share. Also effective December 31, 1996, the Company effected a 2-for-1
split of its common stock. All par value, share and per share information,
common stock options and exercise prices included in these consolidated
financial statements and related footnotes have been restated to reflect the
stock split.
 
3. LEGAL PROCEEDINGS
 
     On October 15, 1996, Union Pacific Resources Company ("UPRC") filed suit
against the Company alleging patent infringement and tortious interference with
contracts regarding confidentiality and proprietary information of UPRC. UPRC is
seeking injunctive relief and damages in an unspecified amount, including
actual, enhanced, consequential and punitive damages. The Company believes it
has meritorious defenses to the allegations, including its belief that the
subject patent is invalid. Given the subject of the claims, the Company is
unable to predict the outcome of the matter or estimate a range of financial
exposure.
 
4. SENIOR NOTES
 
  10 1/2% Notes
 
     The Company has outstanding $90 million in aggregate principal amount of
10 1/2% Notes which mature June 2002. The 10 1/2% Notes bear interest at an
annual rate of 10 1/2%, payable semiannually on each June 1 and December 1. The
10 1/2% Notes are senior, unsecured obligations of the Company, and are fully
and unconditionally guaranteed, jointly and severally, by certain subsidiaries
of the Company (the "Guarantor Subsidiaries").

  9 1/8% Notes
 
     The Company has outstanding $120 million in aggregate principal amount of
9 1/8% Senior Notes due 2006 which mature April 15, 2006. The 9 1/8% Notes bear
interest at an annual rate of 9 1/8%, payable semiannually on each April 15 and
October 15. The 9 1/8% Notes are senior, unsecured obligations of the Company,
and are fully and unconditionally guaranteed, jointly and severally, by the
Guarantor Subsidiaries.
 
     Set forth below are condensed consolidating financial statements of the
Guarantor Subsidiaries, the Non-Guarantor Subsidiaries and the Company. Separate
financial statements of each Guarantor Subsidiary have not been included because
management has determined that they are not material to investors.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     As permitted by the Oklahoma General Corporation Act under which the
Company is incorporated, the Company's Certificate of Incorporation provides for
indemnification of each of the Company's officers and directors against (a)
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with any
action, suit or proceeding brought by reason of his being or having been a
director, officer, employee or agent of the Company, or of any other
corporation, partnership, joint venture, or other enterprise at the request of
the Company, other than an action by or in the right of the Company, provided
that he acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interest of the Company, and with respect to any
criminal action, he had no reasonable cause to believe that his conduct was
unlawful and (b) expenses, including attorneys' fees, actually and reasonably
incurred by him in connection with the defense or settlement of any action or
suit by or in the right of the Company brought by reason of his being or having
been a director, officer, employee or agent of the Company, or any other
corporation, partnership, joint venture, or other enterprise at the request of
the Company, provided that he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interest of the Company, except
that no indemnification shall be made in respect of any claim, issue or matter
as to which he shall have been adjudged liable to the Company, unless and only
to the extent that the court in which such action was decided has determined
that the person is fairly and reasonably entitled to indemnity for such expenses
which the court deems proper. The Company's bylaws provide for similar
indemnification. These provisions may be sufficiently broad to indemnify such
persons for liabilities arising under the Securities Act of 1933, as amended.
 
     The Company has entered into indemnity agreements with each of its
directors and executive officers. Under each indemnity agreement, the Company
will pay on behalf of the indemnitee, and his executors, administrators and
heirs, any amount which he is or becomes legally obligated to pay because of (i)
any claim or claims from time to time threatened or made against him by any
person because of any act or omission or neglect or breach of duty, including
any actual or alleged error or misstatement or misleading statement, which he
commits or suffers while acting in his capacity as a director and/or officer of
the Company or an affiliate or (ii) being a party, or being threatened to be
made a party, to any threatened, pending or contemplated action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was an officer, director, employee or agent of the
Company or an affiliate or is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. The payments which the Company will be
obligated to make thereunder shall include, inter alia, damages, charges,
judgments, fines, penalties, settlements and costs, cost of investigation and
cost of defense of legal, equitable or criminal actions, claims or proceedings
and appeals therefrom, and costs of attachment, supersedeas, bail, surety or
other bonds. The Company also provides liability insurance for each of its
directors and executive officers.

ITEM 22. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
 
          (i) To include any prospectus required by section 10(a)(3) of the
     Securities Act of 1933;
 
          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement;
 
          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the Registration Statement or any
     material change to such information in the Registration Statement.
 
     Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission 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.
 
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registration pursuant to the provisions described under Item 20, 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 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

future net revenue from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines before any
state or federal income taxes, as estimated by independent petroleum engineers
in a reserve report prepared as of the end of the Company's most recently
completed fiscal year, as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of
the Company and its Restricted Subsidiaries attributable to any acquisition
consummated since the date of such year-end reserve report, and (B) estimated
oil and gas reserves of the Company and its Restricted Subsidiaries
attributable to extensions, discoveries and other additions and upward
revisions of estimates of proved oil and gas reserves due to exploration,
development or exploitation, production or other activities conducted or
otherwise occurring since the date of such year-end reserve report, which, in
the case of sub-clauses (A) and (B), would, in accordance with standard
industry practice, result in such increases as calculated in accordance with
SEC guidelines (utilizing the prices utilized in such year-end reserve report),
and decreased by, as of the date of determination, the discounted future net
revenue of (C) estimated proved oil and gas reserves of the Company and its
Restricted Subsidiaries produced or disposed of since the date of such year-end
reserve report and (D) reductions in the estimated oil and gas reserves of the
Company and its Restricted Subsidiaries since the date of such year-end reserve
report attributable to downward revisions of estimates of proved oil and gas
reserves due to exploration, development or exploitation, production or other
activities conducted or otherwise occurring since the date of such year-end
reserve report which, in the case of sub-clauses (C) and (D), would, in
accordance with standard industry practice, result in such decreases as
calculated in accordance with SEC guidelines (utilizing the prices utilized in
such year-end reserve report); provided that, in the case of each of the
determinations made pursuant to clauses (A) through (D), such increases and
decreases shall be as estimated by the Company's engineers, (ii) the

minority interests, (ii) any gas balancing liabilities of the Company and its
Restricted Subsidiaries reflected in the Company's latest annual or quarterly
financial statements, (iii) the discounted future net revenue, calculated in
accordance with SEC guidelines (utilizing the prices utilized in the Company's
year-end reserve report), attributable to reserves which are required to be
delivered to third parties to fully satisfy the obligations of the Company and
its Restricted Subsidiaries with respect to Volumetric Production Payments on
the schedules specified with respect thereto, (iv) the discounted future net
revenue, calculated in accordance with SEC guidelines, attributable to reserves
subject to Dollar-Denominated Production Payments which, based on the estimates
of production included in determining the discounted future net revenue
specified in (a) (i) above (utilizing the same prices utilized in the Company's
year-end reserve report), would be necessary to fully satisfy the payment
obligations of the Company and its Restricted Subsidiaries with respect to
Dollar-Denominated Production Payments on the schedules specified with respect
thereto and (v) the discounted future net revenue, calculated in accordance
with SEC guidelines (utilizing the same prices utilized in the Company's

                                       13
<PAGE>   21
         Securities offered and sold in their initial distribution in reliance
on Regulation S may be initially issued in the form of temporary Global
Securities in fully registered form without interest coupons, substantially in
the form of Exhibit A, with such applicable legends as are provided for in
Exhibit A hereto.  Such temporary Global Securities may be registered in the
name of the Depository or its nominee and deposited with the Trustee, as
custodian for the Depository, duly executed by the Company and authenticated by
the Trustee as hereinafter provided, for credit by the Depository to the
respective accounts of the beneficial owners of the Securities represented
thereby (or such other accounts as they may direct), provided that upon such
deposit all such Securities shall be credited to or through accounts maintained
at the Depository by or on behalf of Euroclear or CEDEL.  Until such time as
the Restricted Period (as defined below) shall have expired, any such temporary
Global Securities, together with their Successor Securities which are Global
Securities other than the Restricted Global Security, shall each be referred to
herein as a "Temporary Regulation S Global Security."  After such time as the
Restricted Period shall have expired and the certifications referred to in the
next succeeding paragraph shall have been provided, interests in such Temporary
Regulation S Global Securities shall be exchanged for interests in like Global
Securities, each referred to herein collectively as a "Permanent Regulation S
Global Security," substantially in the form of Security set forth in Exhibit A,
with such applicable legends as are provided for in Exhibit A.  Such Permanent
Regulation S Global Securities shall be registered in the name of the
Depository or its nominee and deposited with the Trustee, as custodian for the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided, for credit to the respective accounts of the beneficial
owners of the Securities represented thereby (or such other accounts as they
may direct).  The aggregate principal amount of the Temporary Regulation S
Global Security or the Permanent Regulation S Global Security may be increased
or decreased from time to time by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided.  As used
herein, the term "Restricted Period" means the period of 40 days commencing on
the day after the latest of (a) the day on which the Securities are first
offered to persons other than distributors (as defined in Regulation S) in
reliance on Regulation S and (b) the Issue Date.

         Interests in a Temporary Regulation S Global Security may be exchanged
for interests in a Permanent Regulation S Global Security only after (a) the
expiration of the Restricted Period, (b) delivery by a beneficial owner of an
interest therein to Euroclear or CEDEL of a written certification (an "Owner
Securities Certification") substantially in the form of Exhibit C hereto, and
(c) upon delivery by Euroclear or CEDEL to the Trustee of a written
certification (a "Depository Securities Certification") substantially in the
form attached hereto as Exhibit D.  Upon satisfaction of such conditions, the
Trustee will exchange the portion of the Temporary Regulation S Global Security
covered by such certification for interests in a Permanent Regulation S Global
Security.  The delivery by such Holder of a beneficial interest in such
Temporary Regulation S Global Security of such certification shall constitute
an irrevocable instruction by such holder to Euroclear or CEDEL, as the case
may be, to exchange such Holder's beneficial interest in the Temporary
Regulation S Global Security for a beneficial interest in the Permanent
Regulation S Global Security upon the expiration of the Restricted Period in
accordance with the next succeeding paragraph.

         Upon:

<PAGE>   22
                          (i)     the expiration of the Restricted Period;

                          (ii)    receipt by Euroclear or CEDEL, as the case
         may be, of Owner Securities Certifications described in the preceding
         paragraph;

                          (iii)   receipt by the Depository of:

                          (1)     written instructions given in accordance with
                 the Applicable Procedures from an Agent Member directing the
                 Depository to credit or cause to be credited to a specified
                 Agent Member's account a beneficial interest in a Permanent
                 Regulation S Global Security in a principal amount equal to
                 that of the beneficial interest in a corresponding Temporary
                 Regulation S Global Security for which the necessary
                 certifications have been delivered; and

                          (2)     a written order given in accordance with the
                 Applicable Procedures containing information regarding the
                 account of the Agent Member, and the Euroclear or CEDEL
                 account for which such Agent Member's account is held, to be
                 credited with, and the account of the Agent Member to be
                 debited for, such beneficial interest; and

                          (iv)    receipt by the Trustee of notification from
         the Depository of the transactions described in (iii) above and from
         Euroclear or CEDEL, as the case may be, of Depository Securities
         Certifications,

the Trustee, as Registrar (as defined below), shall instruct the Depository to
reduce the principal amount of such Temporary Regulation S Global Security and
to increase the principal amount of such Permanent Regulation S Global
Security, by the principal amount of the beneficial interest in such Temporary
Regulation S Global Security to be so transferred, and to credit or cause to be
credited to the account of the person specified in such instructions a
beneficial interest in such Permanent Regulation S Global Security having a
principal amount equal to the amount by which the principal amount of such
Temporary Regulation S Global Security was reduced upon such transfer.

         Securities offered and sold in their initial distribution in reliance
on Rule 144A under the Securities Act and other than in reliance on Rule 144A
under the Securities Act or Regulation S shall be issued in the form of one or
more Global Securities (collectively, and, together with their Successor
Securities, the "Restricted Global Security") in fully registered form without
interest coupons, substantially in the form of Security set forth in Exhibit A
hereto, with such applicable legends as are provided for in Exhibit A except as
otherwise permitted herein.  Such Restricted Global Security shall be
registered in the name of the Depository or its nominee and deposited with the
Trustee, as custodian for the Depository, duly executed by the Company and
authenticated by the Trustee as hereinafter provided, for credit by the
Depository to the respective accounts of beneficial owners of the securities
represented thereby (or such other accounts as they may direct).





                                       15
<PAGE>   23
The aggregate principal amount of the Restricted Global Security may be
increased or decreased from time to time by adjustments made on the records of
the Trustee, as custodian for the Depository, in connection with a
corresponding decrease or increase in the aggregate principal amount of the
Temporary Regulation S Global Security or the Permanent Regulation S Global
Security, as hereinafter provided.

SECTION  2.2     Execution and Authentication.

         Two Officers of the Company shall sign the Securities on behalf of the
Company, and one Officer of each Subsidiary Guarantor shall sign the notation
on the Securities relating to the Guarantee of such Subsidiary Guarantor on
behalf of such Subsidiary Guarantor, in each case by manual or facsimile
signature.  The Company's seal shall be reproduced on the Securities.

         If an Officer of the Company or any Subsidiary Guarantor whose
signature is on a Security no longer holds that office at the time the Security
is authenticated, the Security shall be valid nevertheless.

         A Security shall not be valid until the Trustee or an authenticating
agent 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 or an authenticating agent shall authenticate Securities
for original issue in the aggregate principal amount of $150,000,000 upon a
written order of the Company signed by two Officers of the Company.  The
aggregate principal amount of Securities outstanding at any time may not exceed
$150,000,000.

         Series B Notes may be issued only in exchange for a like principal
amount of Series A Notes pursuant to an Exchange Offer.

         The principal and interest on Book-Entry Securities shall be payable
to the Depository or its nominee, as the case may be, as the sole registered
owner and the sole holder of the Book-Entry Securities represented thereby.
The principal and interest on Securities in certificated form shall be payable
at the office of the Paying Agent.

         The Trustee may appoint an authenticating agent to authenticate
Securities.  An authenticating agent may authenticate Securities whenever the
Trustee may do so except on original issuance.  Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent.  An authenticating agent has the same rights as an Agent to deal with
the Company or its Affiliates.

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





                                       16
<PAGE>   24
         If the Securities are to be issued in the form of one or more Global
Securities, then the Company shall execute and the Trustee shall authenticate
and deliver one or more Global Securities that shall represent and shall be in
minimum denominations of $1,000.

SECTION  2.3     Registrar and Paying Agent.

         The Company shall maintain an office or agency where the 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").  The Registrar shall keep a register of the Securities and of
their transfer and exchange.  Where the Trustee is acting as or has been
appointed Registrar and/or Paying Agent, the Company may appoint one or more
co- registrars and one or more additional paying agents with the prior consent
of the Trustee, whose consent shall not be unreasonably withheld.  The term
"Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture.  Such agency agreement shall provide for
reasonable compensation for such services.  The agreement shall implement the
provisions of this Indenture that relate to such Agent.  The Company shall
notify the Trustee of the name and address of any such Agent and shall furnish
the Trustee with an executed counterpart of any such agency agreement.  If the
Company fails to maintain or act as Registrar or Paying Agent, the Trustee
shall act as such and shall be duly compensated therefor.

         The Registrar or a co-registrar and a Paying Agent shall be maintained
by the Company in the Borough of Manhattan, the City of New York.  The Company
initially designates the Trustee as the Registrar and Paying Agent.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Securities Custodian with respect to the Global
Securities.

SECTION  2.4     Paying Agent to Hold Money in Trust.

         The Company shall require each Paying Agent other than the Trustee to
hold in trust for the benefit of Holders or the Trustee all money held by such
Paying Agent for the payment of principal of, premium, if any, or interest on
the Securities (whether such money shall have been paid to it by the Company or
any Subsidiary Guarantor), and to notify the Trustee of any Default by the
Company or any Subsidiary Guarantor in making any such payment.  While any such
Default continues, the Trustee may require the Paying Agent to pay all money
held by it to the Trustee.  Except as provided in the immediately preceding
sentence, the Company at any time may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed and, if the
Company requires such payment, the Company shall give prior notice to the
Trustee and provide appropriate money transfer instructions to the Paying
Agent.  Upon such payment over to the Trustee and accounting for any funds
disbursed, such Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money.  If the Company or a Subsidiary acts
as Paying Agent,





                                       17
<PAGE>   25
it shall segregate and hold as separate trust funds for the benefit of the
Holders all money held by it as Paying Agent.

SECTION  2.5     Holder Lists.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders and shall otherwise comply with TIA Section 312(a).  If the Trustee is
not the Registrar, the Company shall furnish or cause to be furnished to the
Trustee at least ten Business Days prior to each semiannual 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, and the Company shall otherwise comply with TIA
Section 312(a).

SECTION  2.6     Transfer and Exchange.

                 (a)      Beneficial interests in a Global Security may,
subject to the restrictions on the transferability of the Securities and upon
delivery of a certificate in the form of Exhibit B hereto be exchanged for
certificated Securities upon request but only upon at least 20 days' prior
written notice given to the Trustee by or on behalf of the Depository (in
accordance with the Depository's customary procedures) and will bear the
applicable legends set forth in Exhibit A hereto.

                 (b)      If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depository or its nominee to the Trustee, as Registrar, for exchange or
cancellation as provided in this Article II.  If any Global Security is to be
exchanged for other Securities or cancelled in part, or if another Security is
to be exchanged in whole or in part for a beneficial interest in any Global
Security, such Global Security shall be so surrendered for exchange or
cancellation as provided in this Article II or, if the Trustee is acting as
custodian for the Depository or its nominee (or is party to a similar
arrangement) with respect to such Global Security, the principal amount thereof
shall be reduced or increased by an amount equal to the portion thereof to be
so exchanged or cancelled, or the principal amount of such other Security to be
so exchanged for a beneficial interest therein, as the case may be, in each
case by means of an appropriate adjustment made on the records of the Trustee,
whereupon the Trustee, in accordance with the Applicable Procedures, shall
instruct the Depository or its authorized representatives to make a
corresponding adjustment to its records (including by crediting or debiting any
Agent Member's account as necessary to reflect any transfer or exchange of a
beneficial interest).  Upon any such surrender or adjustment of a Global
Security, the Trustee shall, subject to this Article II, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered in such names as may
be directed by, the Depository or its authorized representative.  Upon the
request of the Trustee in connection with the occurrence of any of the events
specified in the preceding paragraph or in clause (r) below, the Company shall
promptly make available to the Trustee a reasonable supply of Securities that
are not in the form of Global Securities.  The Trustee shall be entitled to
rely upon any order, direction or request of the





                                       18
<PAGE>   26
Depository or its authorized representative which is given or made pursuant to
this Article II if such order, direction or request is given or made in
accordance with the Applicable Procedures.

                 (c)      Subject to the provisions in the legends required by
this Indenture, the registered Holder may grant proxies and otherwise authorize
any Person, including Agent Members and Persons who may hold interests in Agent
Members to take any action that such Holder is entitled to take under this
Indenture.

                 (d)      Neither Agent Members nor any other Person on whose
behalf Agent Members may act shall have any rights under this Indenture with
respect to any Global Security held on their behalf by the Depository or under
the Global Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever.  Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent
of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of customary practice
governing the exercise of the rights of a Holder of any Security.  With respect
to any Global Security deposited with the Trustee as custodian for the
Depository for credit to their respective accounts (or to such other accounts
as they may direct) at Euroclear or CEDEL, the provisions of the "Operating
Procedures of the Euroclear System" and the "Terms and Conditions Governing Use
of Euroclear," and the "Management Regulations" and "Instructions to
Participants" of CEDEL, respectively, shall be applicable to such Global
Security.

                 (e)      Upon presentation for transfer and exchange of any
Security at the office of the Trustee, as Registrar, located in The City of New
York, accompanied by a written instrument of transfer or exchange in the form
approved by the Company (it being understood that, until notice to the contrary
is given to holders of Securities, the Company shall be deemed to have approved
the form of instrument of transfer or exchange, if any, printed on any
Security), executed by the registered Holder, in person or by such Holder's
attorney thereunto duly authorized in writing, and upon compliance with this
Section 2.6, such Security shall be transferred upon the Register, and a new
Security shall be authenticated and issued in the name of the transferee.
Notwithstanding any provision to the contrary herein or in the Securities,
transfers of a Global Security, in whole or in part, and transfers of interests
therein of the kind described in this Section 2.6, shall only be made in
accordance with this Section 2.6.  Transfers and exchanges subject to this
Section 2.6 shall also be subject to the other provisions of this Indenture
that are not inconsistent with this Section 2.6.

                 (f)      General.  A Global Security may not be transferred,
in whole or in part, to any Person other than the Depository or a nominee
thereof, and no such transfer to any such other Person may be registered;
provided, however, that this clause (f) shall not prohibit any transfer of a
Security that is issued in exchange for a Global Security but is not itself a
Global Security.  No transfer of a Security to any Person shall be effective
under this Indenture or the Securities unless and until such Security has been
registered in the name of such Person.  Nothing in this clause (f) shall
prohibit or





                                       19
<PAGE>   27
render ineffective any transfer of a beneficial interest in a Global Security
effected in accordance with the other provisions of this Section 2.6.

                 (g)      Temporary Regulation S Global Security.  If the
holder of a beneficial interest  in a Temporary Regulation S Global Security
wishes at any time to transfer such interest to a Person who wishes to take
delivery thereof in the form of a beneficial interest in such Temporary
Regulation S Global Security, such transfer may be effected, subject to the
rules and procedures of the Depository, Euroclear and CEDEL, in each case to
the extent applicable and as in effect from time to time (the "Applicable
Procedures"), only in accordance with this clause (g).  Upon delivery (i) by a
beneficial owner of an interest in a Temporary Regulation S Global Security to
Euroclear or CEDEL, as the case may be, of an Owner Securities Certification,
(ii) by the transferee of such beneficial interest in the Temporary Regulation
S Global Security to Euroclear or CEDEL, as the case may be, of a written
certification (a "Transferee Securities Certification") substantially in the
form of Exhibit E hereto and (iii) by Euroclear or CEDEL, as the case may be,
to the Trustee, as Registrar, of a Depository Securities Certification, the
Trustee may direct either Euroclear or CEDEL, as the case may be, to reflect on
its records the transfer of a beneficial interest in the Temporary Regulation S
Global Security from the beneficial owner providing the Owner Securities
Certification to the Person providing the Transferee Securities Certification.

                 (h)      Restricted Global Security to Temporary Regulation S
Global Security.  If the holder of a beneficial interest in the Restricted
Global Security wishes at any time to transfer such interest to a Person who
wishes to take delivery thereof in the form of a beneficial interest in the
Temporary Regulation S Global Security, such transfer may be effected, subject
to the Applicable Procedures, only in accordance with the provisions of this
clause (h) and clause (n) below.  Upon receipt by the Trustee, as Registrar, of
(A) written instructions given by or on behalf of the Depository in accordance
with the Applicable Procedures directing the Trustee to credit or cause to be
credited to a specified Agent Member's account a beneficial interest in the
Temporary Regulation S Global Security in a specified principal amount and to
cause to be debited from another specified Agent Member's account a beneficial
interest in the Restricted Global Security in an equal principal amount and (B)
a certificate in substantially the form set forth in Exhibit F hereto signed by
or on behalf of the holder of such beneficial interest in the Restricted Global
Security, the Trustee, as Registrar, shall, subject to clause (n) below, reduce
the principal amount of the Restricted Global Security, and increase the
principal amount of the Temporary Regulation S Global Security by such
specified principal amount.

                 (i)      Restricted Global Security to Permanent Regulation S
Global Security.  If the holder of a beneficial interest in the Restricted
Global Security wishes at any time to transfer such interest to a Person who
wishes to take delivery thereof in the form of a beneficial interest in the
Permanent Regulation S Global Security, such transfer may be effected, subject
to the Applicable Procedures, only in accordance with this clause (i).  Upon
receipt by the Trustee, as Registrar, of (A) written instructions given by or
on behalf of the Depository in accordance with the Applicable Procedures
directing the Trustee to credit or cause to be credited to a specified Agent
Member's account a beneficial interest in the Permanent Regulation S Global
Security in a specified principal





                                       20
<PAGE>   28
amount and to cause to be debited from another specified Agent Member's account
a beneficial interest in the Restricted Global Security in an equal principal
amount and (B) a certificate in substantially the form set forth in Exhibit G
hereto signed by or on behalf of the holder of such beneficial interest in the
Restricted Global Security, the Trustee, as Registrar, shall reduce the
principal amount of a Restricted Global Security, and increase the principal
amount of the Permanent Regulation S Global Security by such specified
principal amount.

                 (j)      Temporary Regulation S Global Security or Permanent
Regulation S Global Security to Restricted Global Security.  If the holder of a
beneficial interest in the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security at any time, wishes to transfer such
interest to a Person who wishes to take delivery thereof in the form of a
beneficial interest in the Restricted Global Security, such transfer may be
effected, subject to the Applicable Procedures, only in accordance with this
clause (j) and clause (n) below; provided, that with respect to any transfer of
a beneficial interest in a Temporary Regulation S Global Security, the
transferor and Euroclear or CEDEL, as the case may be, must have previously
delivered an Owner Securities Certification and a Depository Securities
Certification respectively, with respect to such beneficial interest.  Upon
receipt by the Trustee, as Registrar, of (A) written instructions given by or
on behalf of the Depository in accordance with the Applicable Procedures
directing the Trustee to credit or cause to be credited, to a specified Agent
Member's account a beneficial interest in the Restricted Global Security in a
specified principal amount and to cause to be debited from another specified
Agent Member's account a beneficial interest in the Temporary Regulation S
Global Security or the Permanent Regulation S Global Security, as the case may
be, in an equal principal amount and (B) a certificate in substantially the
form set forth in Exhibit H signed by or on behalf of the holder of such
beneficial interest in the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security, as the case may be, the Trustee, as
Security Registrar, shall, subject to clause (n) below, reduce the principal
amount of such Temporary Regulation S Global Security or Permanent Regulation S
Global Security, as the case may be, and increase the principal amount of the
Restricted Global Security by such specified principal amount.

                 (k)      Non-Global Restricted Security to Restricted Global
Security.  If the holder of a Restricted Security (other than a Global
Security) wishes at any time to transfer all or any portion of such Security to
a Person who wishes to take delivery thereof in the form of a beneficial
interest in the Restricted Global Security, the Temporary Regulation S Global
Security or the Permanent Regulation S Global Security, such transfer may be
effected, subject to the Applicable Procedures, only in accordance with this
clause (k) and clause (n) below.  Upon receipt by the Trustee, as Registrar, of
(A) such Security and written instructions given by or on behalf of such Holder
as provided in this Section 2.6 directing the Trustee to credit or cause to be
credited to a specified Agent Member's account a beneficial interest in the
Restricted Global Security, the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security, as the case may be, in a specified
principal amount equal to the principal amount of the Restricted Security (or
portion thereof) to be so transferred, and (B) an appropriately completed
certificate substantially in the form set forth in Exhibit I-1 hereto, if the
specified account is to be credited with a beneficial interest in the
Restricted Global Security, or Exhibit I-2 herein, if the specified account is
to be





                                       21
<PAGE>   29
credited with a beneficial interest in the Temporary Regulation S Global
Security or the Permanent Regulation S Global Security, signed by or on behalf
of such Holder, then the Trustee, as Registrar, shall, subject to clause (n)
below, cancel such Restricted Security (and issue a new Security in respect of
any untransferred portion thereof) as provided in this Section 2.6 and increase
the principal amount of the Restricted Global Security, Temporary Regulation S
Global Security or Permanent Regulation S Global Security, as the case may be,
by the specified principal amount.

                 (l)      Non-Global Permanent Regulation S Security to
Restricted Global Security or Permanent Regulation S Global Security.  If the
Holder of a Permanent Regulation S Security (other than a Global Security)
wishes at any time to transfer all or any portion of such Security to a Person
who wishes to take delivery thereof in the form of a beneficial interest in the
Restricted Global Security or the Permanent Regulation S Global Security, as
the case may be, such transfer may be effected only in accordance with this
clause (1) and subject to the Applicable Procedures.  Upon receipt by the
Trustee, as Registrar, of (A) such Security and instructions given by or on
behalf of such Holder as provided in this Section 2.6 directing the Trustee to
credit or cause to be credited to a specified Agent Member's account a
beneficial interest in the Restricted Global Security or the Permanent
Regulation S Global Security, as the case may be, in a principal amount equal
to the principal amount of the Security (or portion thereof) to be so
transferred, and (B) (i) with respect to a transfer which is to be delivered in
the form of a beneficial interest in the Restricted Global Security, a
certificate in substantially the form set forth in Exhibit J-1 hereto, signed
by or on behalf of such Holder, and (ii) with respect to a transfer which is to
be delivered in the form of a beneficial interest in the Permanent Regulation S
Global Security, a certificate in substantially the form set forth in Exhibit
J-2 hereto, signed by or on behalf of such Holder, then the Trustee, as
Registrar, shall, subject to clause (q) below, cancel such Security (and issue
a new Security in respect of any untransferred portion thereof) as provided in
this Section 2.6 and increase the principal amount of the Restricted Global
Security, or the Permanent Regulation S Global Security, as the case may be, by
the specified principal.

                 (m)      Other Exchanges.  Securities that are not Global
Securities may be exchanged (on transfer or otherwise) for Securities that are
not Global Securities or for beneficial interests in a Global Security (if any
is then outstanding) only in accordance with such procedures, which shall be
substantially consistent with the provisions of clauses (f) through (l) above
(including the certification requirements intended to insure that transfers of
beneficial interests in a Global Security comply with Rule 144A under the
Securities Act or Regulation S, as the case may be) and any Applicable
Procedures, as may from time to time be adopted by the Company and the Trustee.

                 (n)      Interests in Temporary Regulation S Global Security
to be Held Through Euroclear or CEDEL.  Until the later of the expiration of
the Restricted Period and the provision of the Owner Securities Certification
and the Depository Securities Certification, beneficial interests in any
Temporary Regulation S Global Security may be held only in or through accounts
maintained at the Depository by Euroclear or CEDEL (or by Agent Members acting
for the account thereof).





                                       22
<PAGE>   30
                 (o)      When Securities in certificated form are presented to
the Registrar with a request to register the transfer of such Securities or to
exchange such Securities for an equal principal amount of Securities of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing.  To permit registrations of
transfers and exchanges, the Company shall execute and the Trustee shall
authenticate Securities at the Registrar's request.  No service charge shall be
made for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer taxes or
similar governmental charge payable upon exchanges or transfers pursuant to
Sections 2.2, 2.10, 3.7 or 9.5).  The Registrar shall not be required to
register the transfer of or exchange of any Security (i) during a period
beginning at the opening of business 15 days before the mailing of a notice of
redemption of Securities and ending at the close of business on the day of such
mailing and (ii) selected for redemption in whole or in part pursuant to
Article Three, except the unredeemed portion of any Security being redeemed in
part.

                 (p)      If a Series A Note is a Restricted Security in
certificated form, then as provided in this Indenture and subject to the
limitations herein set forth, the Holder, provided it is a Qualified
Institutional Buyer or an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act), may exchange such
Security for a Book-Entry Security by instructing the Trustee (by completing
the Transferee Certificate in the form of Exhibit B hereto) to arrange for such
Series A Note to be represented by a beneficial interest in a Global Security
in accordance with the customary procedures of the Depository.

                 (q)      Upon any exchange provided for in Section 2.6(a), the
Company shall execute and the Trustee shall authenticate, and deliver to the
person specified by the Depository a new Series A Note or Notes registered in
such names and in such authorized denominations as the Depository, pursuant to
the instructions of the beneficial owner of the Securities requesting the
exchange, shall instruct the Trustee.  Thereupon, the beneficial ownership of
such Global Security shown on the records maintained by the Depository or its
nominee shall be reduced by the amounts so exchanged and an appropriate
endorsement be made by and on behalf of the Trustee on the Global Security.
Any such exchange shall be effected through the Depository in accordance with
the procedures of the Depository therefor.

                 (r)      Notwithstanding the foregoing, no Global Security
shall be registered for transfer or exchange, or authenticated and delivered,
whether pursuant to this Section, Section 2.7, 2.10 or 3.7 or otherwise , in
the name of a person other than the Depository for such Global Security or its
nominee until (i) the Depository notifies the Company that it is unwilling or
unable to continue as Depository for such Global Security or if at any time the
Depository ceases to be a clearing agency registered under the Exchange Act,
and a successor depository is not appointed by the Company within 30 days, (ii)
the Company executes and delivers to the Trustee a Company order





                                       23
<PAGE>   31
that all such Global Securities shall be exchangeable or (iii) there shall have
occurred and be continuing an Event of Default.  Upon the occurrence in respect
of any Global Security representing the Series A Notes of any one or more of
the conditions specified in clause (i), (ii) or (iii) of the preceding
sentence, such Global Security may be registered for transfer or exchange for
Series A Notes registered in the names of, authenticated and delivered to, such
persons as the Trustee or the Depository, as the case may be, shall direct.

                 (s)      Except as provided above, any Security authenticated
and delivered upon registration of transfer of, or in exchange for, or in lieu
of, any Global Security, whether pursuant to this Section 2.7, 2.10 or 3.7 or
otherwise, shall also be a Global Security and bear the legend specified in
footnote 1 to Exhibit A.

SECTION  2.7     Replacement Securities.

         If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security claims that the Security has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of the Trustee are met.  An indemnity bond may be
required by the Trustee, the Company or any Subsidiary Guarantor that is
sufficient in the judgment of the Company, the Subsidiary Guarantors and the
Trustee to protect the Company, the Subsidiary Guarantors, the Trustee or any
Agent from any loss which any of them may suffer if a Security is replaced.
The Company may charge for its expenses (including fees and expenses of the
Trustee) in replacing a Security.

SECTION  2.8     Outstanding Securities.

         Senior Notes outstanding at any time are all Securities authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section 2.8 as not outstanding.  Except as set forth in Section 2.9, a
Security does not cease to be outstanding because the Company, the Subsidiary
Guarantors or any of their respective Subsidiaries or Affiliates holds the
Security.

         If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the principal amount of any Security is considered paid under
Section 4.1, it ceases to be outstanding and interest on it ceases to accrue.

SECTION  2.9     Treasury Securities.

         In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, any Subsidiary Guarantor or an Affiliate of the Company shall
be considered as though they are not outstanding,





                                       24
<PAGE>   32
except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities
which the Trustee knows are so owned shall be so disregarded.

SECTION  2.10    Temporary Securities.

         Until definitive Securities are ready for delivery, the Company may
prepare and, upon written order of the Company, the Trustee shall authenticate
temporary Securities.  Temporary Securities shall be substantially in the form
of definitive Securities but may have variations that the Company considers
appropriate for temporary Securities.  Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate and deliver definitive
Securities in exchange for a like principal amount of temporary Securities
surrendered to it.  Until so exchanged, temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

SECTION  2.11    Cancellation.

         The Company or any Subsidiary Guarantor at any time may deliver
Securities to the Trustee for cancellation.  The Registrar and Paying Agent
shall forward to the Trustee any Securities surrendered to them for transfer,
exchange or payment.  The Trustee shall cancel all Securities surrendered for
registration, transfer, exchange, payment or cancellation and shall destroy
canceled Securities unless the Company directs their return to the Company.
Except as provided in Section 2.7, the Company may not issue new Securities to
replace Securities that it has paid or delivered to the Trustee for
cancellation.

         Securities that are redeemed by the Company or that are otherwise
acquired by the Company, will be surrendered to the Trustee for cancellation.

SECTION  2.12    Defaulted Interest.

         If the Company defaults in a payment of interest on the Securities, it
shall pay, or cause the Paying Agent to pay, the defaulted interest in any
lawful manner (plus interest on such defaulted interest to the extent lawful)
(taken together, the "Defaulted Interest") to the persons who are Holders on a
subsequent special record date, in each case at the rate provided in the
Securities and in Section 4.1 hereof.  At least 15 days before the special
record date, the Company shall mail to each Holder a notice stating the special
record date, the payment date and the amount of Defaulted Interest to be paid.
In the event that the Company has elected to cause a Paying Agent to pay the
Defaulted Interest, the Company shall so notify the Paying Agent at least 15
days before the special record date, which notice shall also set forth the
special record date, the payment date and the aggregate amount of Defaulted
Interest to be paid.  At least five days before such payment date, the Company
shall deposit with the Paying Agent money sufficient to pay all of the
Defaulted Interest on the payment date therefor and instruct the Paying Agent
in writing to pay to specified Holders on the payment date.  On the payment
date, the Paying Agent shall make the payments in accordance with





                                       25
<PAGE>   33
the Company's written instructions from funds deposited with the Paying Agent
for the purpose of making such Defaulted Interest payments.

SECTION  2.13    Persons Deemed Owners.

         The Company, the Trustee, any Paying Agent and any authenticating
agent may treat the Person in whose name any Security (including, without
limitation, any Global Security) is registered as the owner of such Security
for the purpose of receiving payments of principal of, premium, if any, or
interest on such Security and for all other purposes.  None of the Company, the
Trustee, any Paying Agent or any authenticating agent shall be affected by any
notice to the contrary.

                                  ARTICLE III

                                   REDEMPTION


SECTION  3.1     Notice to Trustee.

         If the Company elects to redeem Securities pursuant to the optional
redemption provisions of Paragraphs 6 or 7 of the Securities, it shall furnish

before the redemption date (unless the Trustee consents to a shorter period in

SECTION  3.2     Selection of Securities to Be Redeemed.

         If less than all of the Securities are to be redeemed at any time, the
Trustee shall select the Securities to be redeemed pro rata, by lot or, if the
Securities are listed on any securities exchange, by any other method that the
Trustee considers fair and appropriate and that complies with the requirements
of such exchange; provided, however, that no Securities with a principal amount
of $1,000 or less will be redeemed in part.  The Trustee shall make the
selection from outstanding Securities not previously called for redemption not
less than 30 nor more than 45 days prior to the redemption date.  Securities
and portions of them it selects shall be in amounts of $1,000 or whole
multiples 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 selected for redemption.

SECTION  3.3     Notice of Redemption.

                 (a)      At least 30 days but not more than 60 days before a

                          (iii)   the redemption price;

                          (iv)    the aggregate principal amount of Securities
         being redeemed;

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

                          (vi)    that Securities called for redemption must be
         surrendered to the Paying Agent at the address specified in such
         notice to collect the redemption price;

                          (vii)   that, unless the Company defaults in the
         payment of the redemption price or accrued interest, interest on
         Securities called for redemption ceases to accrue on and after the
         redemption date and the only remaining right of the Holders is to
         receive payment of the redemption prices in respect of the Securities
         upon surrender to the Paying Agent of the Securities;

                          (viii)  if any Security is being redeemed in part,
         the portion of the principal amount of such Security to be redeemed
         and that, after the redemption date, upon surrender of such Security,
         a new Security or Securities in principal amount equal to the
         unredeemed portion will be issued in the name of the Holder thereof
         upon cancellation of the Security or Securities being redeemed;

                          (ix)    the paragraph of the Securities pursuant to
         which the Securities called for redemption are being redeemed; and

                          (x)     the CUSIP number of the Securities.

                 (b)      At the Company's request, the Trustee shall give the
notice of redemption required in Section 3.3(a) in the Company's name and at
the Company's expense; provided, however, that the Company shall deliver to the
Trustee, at least 45 days prior to the redemption date (unless the Trustee
consents to a shorter notice period in writing), an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in Section 3.3(a).

SECTION  3.4     Effect of Notice of Redemption.

         Once notice of redemption is mailed in accordance with Section 3.3,
Securities called for redemption become due and payable on the redemption date
at the redemption price.  Upon surrender to the Paying Agent, such Securities
shall be paid at the redemption price, plus accrued  and unpaid interest to the

any money so deposited which is not required for that purpose upon the written
request of the Company, except with respect to monies owed as obligations to
the Trustee pursuant to Article Seven.

         If any Security called for redemption shall not be so paid upon
redemption because of the failure of the Company to comply with the preceding
paragraph, interest will continue to be payable on the unpaid principal and
premium, if any, including from the redemption date until such principal and
premium, if any, is paid, and, to the extent lawful, on any interest not paid
on such unpaid principal, in each case at the rate provided in the Securities
and in Section 4.01 hereof.

SECTION  3.6     Securities Redeemed in Part.

         Upon surrender of a Security that is to be redeemed in part, the
Company shall issue and the Trustee shall authenticate for the Holder, at the
expense of the Company, a new Security equal in aggregate amount to the
unredeemed portion of the Security surrendered.

SECTION  3.7     Optional Redemption at Make-Whole Price.

         At any time, the Company may, at its option, redeem all or any portion
of the Securities at the "Make-Whole Price" (hereinafter defined) plus accrued
and unpaid interest to the date of redemption.  For purposes hereof, the term
"Make-Whole Price" means the sum of (i) the outstanding principal amount of the
Securities plus (ii) the Make-Whole Amount.

         Any redemption pursuant to this Section 3.7 shall be made, to the

any, on the Securities are prohibited or, if such event has occurred, a
description of the event and what action the Company and the Subsidiary

nothing has come to their attention that would lead them to believe that the
Company has violated any provisions of Sections 4.7, 4.8, 4.9 or 4.10 of this
Indenture (to the extent such provisions relate to accounting matters) or, if
any such violation has occurred, specifying the nature and period of existence
thereof.  Where such financial statements are not accompanied by such a written
statement, the Company shall furnish the Trustee with an Officers' Certificate
stating that any such written statement would be contrary to the then current

                 (c)      The Company and the Subsidiary Guarantors will, so
long as any of the Securities are outstanding, deliver to the Trustee forthwith

         Subject to Section 2.3, the Company may also from time to time
designate one or more other offices or agencies where the Securities may be

rescind such designations; provided, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in the Borough of Manhattan, The City of New York, for such purposes.
The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

(charter and statutory) and franchises of the Company and the Subsidiaries;
provided, that the Company shall not be required to preserve the corporate
existence of any Subsidiary, or any such right or franchise, if the Board of

that each may lawfully do so) that it will not at any time insist upon, plead,

stay, extension, or usury law or other law, which would prohibit or forgive the
Company or any Subsidiary Guarantor from paying all or any portion of the
principal of, premium, if any, or interest on the Securities as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this Indenture; and (to the extent
that it may lawfully do so) each of the Company and the Subsidiary Guarantors
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

SECTION  4.7     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 taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary and (b)

improvements thereof, all as in the judgment of the Company may be necessary so

or disposal is, in the judgment of the Company, desirable in the conduct of its
business and not disadvantageous in any material respect to the Holders.

                 (b)      The Company shall provide or cause to be provided,
for itself and each of its Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the reasonable,

                 Subsidiary Guarantor or any other Restricted Subsidiary in an

                 insurance coverage by a third party insurer which is
                 acknowledged in writing by such insurer) that has not been
                 vacated, discharged, satisfied or stayed pending appeal within

Bankruptcy Law.

SECTION  6.2     Acceleration.

         If an Event of Default (other than an Event of Default specified in
clauses 8 or 9) under Section 6.1 occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% of the principal
amount of the outstanding Securities may declare the unpaid principal of and
premium, if any, or the Change of Control purchase price if the Event of
Default includes failure to pay the Change of Control purchase price, and
accrued and unpaid interest on, all the Securities then outstanding to be due
and payable, by a notice in writing to the Company (and to the Trustee, if
given by Holders), and upon any such declaration such principal, premium, if
any, and accrued and unpaid interest shall become immediately due and payable,
notwithstanding anything contained in this Indenture or the Securities to the
contrary.  If an Event of Default specified in clauses 8 or 9 above occurs, all
unpaid principal of, and premium, if any, and accrued and unpaid interest on,
the Securities then outstanding will become due and payable, without any
declaration or other act on the part of the Trustee or any Holder.

         The Holders of a majority of the principal amount of the outstanding
Securities, by written notice to the Company, the Subsidiary Guarantors and the
Trustee, may rescind and annul a declaration of acceleration and its
consequences if (1) the Company or any Subsidiary Guarantor has paid or
deposited with such Trustee a sum sufficient to pay (A) all overdue
installments of interest





                                       37
<PAGE>   45
on all the Securities, (B) the principal of, and premium, if any, on any
Securities that have become due otherwise than by such declaration of
acceleration and interest thereon at the rate or rates prescribed therefor in
the Securities, (C) to the extent that payment of such interest is lawful,
interest on the defaulted interest at the rate or rates prescribed therefor in
the Securities, and (D) all money paid or advanced by the Trustee thereunder
and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; (2) all Events of Default, other than the
non-payment of the principal of any Securities that have become due solely by
such declaration of acceleration, have been cured or waived as provided in this
Indenture; and (3) the rescission would not conflict with any judgment or
decree of a court of competent jurisdiction.  No such rescission will affect
any subsequent Event of Default or impair any right consequent thereon.


SECTION  6.3     Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may, but
is not obligated to, pursue, in its own name and as trustee of an express
trust, any available remedy by proceeding at law or in equity to collect the
payment of principal or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.  If an Event
of Default specified under clauses (8) or (9) of Section 6.1 occurs with
respect to the Company at a time when the Company is the Paying Agent, the
Trustee shall automatically assume the duties of Paying Agent.

         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  6.4     Waiver of Past Defaults.

         Subject to Sections 6.7 and 9.2, the Holders of at least a majority of
the principal amount of the outstanding Securities by notice to the Trustee may
waive an existing Default or Event of Default and its consequences, except a
Default or Event of Default in payment of principal or interest on the
Securities, including any optional redemption payments or Change of Control or
Net Proceeds Offer payments.

SECTION  6.5     Control by Majority.

         The Holders of a majority in principal amount of the Securities 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, provided that (1) such direction is not in
conflict with any rule of law or with this Indenture and (2) the Trustee may
take any other action deemed proper by such Trustee that is not inconsistent
with such direction.

SECTION  6.6     Limitation on Remedies.

         No Holder of any of the Securities will have any right to institute
any proceeding, judicial or otherwise, or for the appointment of a receiver or
trustee or pursue any remedy under this Indenture, unless:

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

                                  (2)      the Holders of not less than 25% of
                 the principal amount of the outstanding Securities have made
                 written request to such Trustee to institute proceedings in
                 respect of such Event of Default in its own name as Trustee
                 under this Indenture,

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

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

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

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

SECTION  6.7     Rights of Holders to Receive Payment.

         Notwithstanding any other provision of this Indenture, the Holder of
any Securities will have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on such Securities on the
stated maturity therefor and to institute suit for the enforcement of any such
payment, and such right may not be impaired without the consent of such Holder.

SECTION  6.8     Collection Suit by Trustee.

         If an Event of Default in payment of principal, premium, if any, or
interest specified in Section 6.1(1), (2) or (3) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company or any Subsidiary Guarantor for the whole amount of
principal, premium, if any, and interest remaining unpaid with respect to the
Securities, and interest on overdue principal and premium, if any, and, to the
extent lawful, interest on overdue interest, and such further amounts as shall
be sufficient to cover the costs and expenses





                                       39
<PAGE>   47
of collection, including the reasonable compensation and expenses of the
Trustee, its agents and counsel.

SECTION  6.9     Trustee May File Proofs of Claim.

                 (a)      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, the Subsidiary Guarantors, their creditors or their
property and may collect and receive any money or securities or other property
payable or deliverable on any such claims and to distribute the same.

                 (b)      Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION  6.10    Priorities.

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

         First:  to the Trustee for amounts due under Section 7.7;

         Second:  to Holders for amounts due and unpaid on the Securities for
principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Securities for principal and
interest, respectively; and

         Third:    To the Company.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10.

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 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.7, or a suit by Holders of more than 10% in principal
amount of the then outstanding Securities.

                                    TRUSTEE


SECTION  7.1     Duties of Trustee.

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

Except during the continuance of an Event of Default:

                          (i)     The Trustee need perform only those duties
         that are specifically set forth (or incorporated by reference) in this
         Indenture and no others.

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

                          (iii)   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:

                          (iv)    This paragraph (c) does not limit the effect 
         of paragraph (b) of this Section.

                          (v)     The Trustee shall not be liable for any error
         of judgment made in good faith by an officer of the Trustee, unless it
         is proved that the Trustee was negligent in ascertaining the pertinent
         facts.

                          (vi)    The Trustee shall not be liable with respect
         to action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.5, and the Trustee
         shall be entitled from time to time to request such a direction.

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

                 (c)      The Trustee shall be under no obligation and may
refuse to perform any duty or exercise any right or power unless it receives
indemnity satisfactory to it against any loss, liability or expense.  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





                                       41
<PAGE>   49
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.

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

SECTION  7.2     Rights of Trustee.

         Subject to Section 7.1:

                 (a)      The Trustee may rely on and shall be protected in
acting or refraining from acting upon any document believed by it to be genuine
and to have been signed or presented by the proper person.  The Trustee shall
not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee
shall determine to make such further inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company, personally
or by agent or attorney, to the extent reasonably required by such inquiry or
investigation.

                 (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 such certificate or opinion.

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

                 (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.

SECTION  7.3     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
Subsidiaries or Affiliates with the same rights it would have if it were not
Trustee.  Any Agent may do the same with like rights.  However, the Trustee
must comply with Sections 7.10 and 7.11.

SECTION  7.4     Trustee's Disclaimer.

         The Trustee 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 or





                                       42
<PAGE>   50
any prospectus, offering or solicitation documents, and it shall not be
responsible for any statement in the Securities other than its certificate of
authentication.

SECTION  7.5     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 pursuant to Section 11.2 a
notice of the Default within 90 days after it occurs.  Except in the case of a
Default in any payment on any Security, the Trustee may withhold the notice if
and so long as the board of directors, executive committee or a trust committee
of officers in good faith determines that withholding the notice is in the
interests of Holders.

SECTION  7.6     Reports by Trustee to Holders.

         Within 60 days after each May 15, beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to each Holder a brief
report dated as of such May 15 that complies with TIA Section 313(a), but only
if such report is required in any year under TIA Section 313(a).  The Trustee
also shall comply with TIA Sections 313(b) and 313(c).

         A copy of each report at the time of its mailing to Holders shall be
filed with the SEC and each stock exchange on which the Securities are listed.
The Company shall notify the Trustee in writing when the Securities become
listed on any national securities exchange or of any delisting thereof.

SECTION  7.7     Compensation and Indemnity.

         The Company and the Subsidiary Guarantors jointly and severally agree
to pay the Trustee from time to time reasonable compensation for its services
(which compensation shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust).  The Company and the
Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon
request for all reasonable out-of-pocket expenses, disbursements and advances
incurred by it.  Such expenses shall include when applicable the reasonable
compensation and expenses of the Trustee's agents and counsel.

         The Trustee shall not be under any obligation to institute any suit,
or take any remedial action under this Indenture, or to enter any appearance or
in any way defend any suit in which it may be a defendant, or to take any steps
in the execution of the trusts created hereby or thereby or in the enforcement
of any rights and powers under this Indenture, until it shall be indemnified to
its satisfaction against any and all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provisions of
this Indenture, including compensation for services, costs, expenses, outlays,
counsel fees and other disbursements, and against all liability not due to its
negligence or willful misconduct.  The Company and the Subsidiary Guarantors
jointly and severally agree to indemnify the Trustee against any loss,
liability or expenses incurred by it arising out of or in connection with the
acceptance and administration of the trust and its duties





                                       43
<PAGE>   51
hereunder as Trustee, Registrar and/or Paying Agent, including the costs and
expenses of enforcing this Indenture against the Company (including with
respect to this Section 7.7) and of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers
or duties hereunder.  The Trustee shall notify the Company and the Subsidiary
Guarantors of any claim for which it may seek indemnity; however, unless the
position of the Company is prejudiced by such failure, the failure of the
Trustee to promptly notify the Company shall not limit its right to
indemnification.  The Company shall defend each such claim and the Trustee
shall cooperate in the defense.  The Trustee may retain separate counsel and
the Company shall reimburse the Trustee for the reasonable fees and expenses of
such counsel.  The Company need not pay for any settlement made without its
consent.

         Neither the Company nor the Subsidiary Guarantors shall be obligated
to reimburse any expense or indemnify against any loss or liability incurred by
the Trustee through the Trustee's negligence or willful misconduct.

         To secure the payment obligations of the Company and the Subsidiary
Guarantors in this Section, the Trustee shall have a claim prior to that of the
Holders of the Securities on all money or property held or collected by the
Trustee, except that held in trust to pay principal of and interest on
particular Securities.  The Trustee's right to receive payment of any amounts
due under this Section 7.7 shall not be subordinate to any other liability or
Indebtedness of the Company.

         When the Trustee incurs expenses or renders services after the
occurrence of any Event of Default specified in Sections 6.1(8) or (9), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law.

SECTION  7.8     Replacement of Trustee.

                          (i)     The Trustee may resign by so notifying the
         Company and the Subsidiary Guarantors.  The Holders of a majority in
         principal amount of the Securities may remove the Trustee by so
         notifying the Trustee, in writing.  The Company may remove the Trustee
         if:

                          (ii)    the Trustee fails to comply with Section 7.1;

                          (iii)   the Trustee is adjudged a bankrupt or an
         insolvent;

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

                          (v)     the Trustee becomes incapable of acting as
         Trustee hereunder.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.  Within one year after the





                                       44
<PAGE>   52
successor Trustee takes office, the Holders of a majority in principal amount
of the Securities may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company and the Subsidiary
Guarantors.  Immediately after that, the retiring Trustee shall transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.7, 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.  A successor Trustee
shall mail notice of its succession to each Holder.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or
the Holders of a majority in principal amount of the Securities may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.  Any successor Trustee shall comply
with TIA Section 310(a)(5).

SECTION  7.9     Successor Trustee by Merger, etc.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust assets to, another corporation, the
successor corporation without any further act shall be the successor Trustee;
provided such corporation or association shall be otherwise eligible and
qualified under this Article.

SECTION  7.10    Eligibility; Disqualification.

         This Indenture shall always have a Trustee which satisfies the
requirements of TIA Section 310(a)(1).  The Trustee shall always 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 also comply
with TIA Section 310(b).

SECTION  7.11    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 VIII

                             DISCHARGE OF INDENTURE


SECTION  8.1     Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, with respect
to the Securities, elect to exercise its rights pursuant to either Section 8.2
or 8.3 with respect to all outstanding Securities upon compliance with the
conditions set forth below in this Article Eight.

SECTION  8.2     Legal Defeasance and Discharge.

         Upon the Company's exercise under Section 8.1 of the option applicable
to this Section 8.2, the Company and the Subsidiary Guarantors shall be deemed
to have been discharged from their obligations with respect to all outstanding
Securities on the date all conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Securities, which shall thereafter
be deemed to be "outstanding" only for the purposes of Section 8.5 and the
other Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Securities and this Indenture
(and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which
shall survive until otherwise terminated or discharged hereunder: (a) the
rights of Holders of outstanding Securities to receive solely from the trust
fund described in Section 8.4, and as more fully set forth in such Section,
payments in respect of the principal of, premium, if any, and interest on such
Securities when such payments are due, (b) the Company's obligations with
respect to such Securities under Sections 2.3, 2.4, 2.6, 2.7, 2.10 and 4.4, (c)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company's obligations in connection therewith (including, but not limited
to, Section 7.7) and (d) this Article Eight.  Subject to compliance with this
Article Eight, the Company may exercise its option under this Section 8.2
notwithstanding the prior exercise of its option under Section 8.3 with respect
to the Securities.

SECTION  8.3     Covenant Defeasance.

         Upon the Company's exercise under Section  8.1 of the option
applicable to this Section 8.3, the Company shall be released from its
obligations under the covenants contained in Sections 4.7, 4.8, 4.9 and 4.10
and Article Five with respect to the outstanding Securities on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Securities shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
outstanding for accounting purposes).  For this





                                       46
<PAGE>   54
purpose, such Covenant Defeasance means that, with respect to the outstanding
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.1(5),
but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.  In addition, upon the Company's
exercise under Section 8.1 of the option applicable to this Section 8.3,
Sections 6.1(4) through 6.1(9) shall not constitute Events of Default.

SECTION  8.4     Conditions to Legal or Covenant Defeasance.

         The following shall be the conditions to application of either Section
8.2 or Section 8.3 to the outstanding Securities:

                 (a)      The Company shall irrevocably have deposited or cause
to be deposited with the Trustee (or another trustee satisfying the
requirements of Section 7.10 who shall agree to comply with the provisions of
this Article Eight applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Securities, (a) cash in
U.S. Legal Tender in an amount, or (b) non-callable U.S. Government Securities
which through the scheduled payment of principal and interest in respect
thereof in accordance with their terms will provide, not later than one day
before the due date of any payment, cash in U.S. Legal Tender in an amount, or
(c) a combination thereof, in such amounts, as will be sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge the principal of, premium, if any, and interest
on the outstanding Securities on the Maturity Date or on the applicable
redemption date, as the case may be, of such principal or installment of
principal, premium, if any, or interest and in accordance with the terms of
this Indenture and of such Securities; provided that the Trustee shall have
been irrevocably instructed to apply such money or the proceeds of such non-
callable Government Securities to said payments with respect to the Securities.

                 (b)      In the case of an election under Section 8.2, the
Company shall have delivered to the Trustee an Opinion of Counsel confirming
that (i) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (ii) since the date hereof, there has been
a change in the applicable federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of the
outstanding Securities will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;





                                       47
<PAGE>   55
                 (c)      In the case of an election under Section 8.3, the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of the outstanding Securities 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;

                 (d)      No Default or Event of Default with respect to the
Securities shall have occurred and be continuing on the date of such deposit
or, insofar as Subsection 6.1(8) or 6.1(9) is concerned, at any time in the
period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period);

                 (e)      Such Legal Defeasance or Covenant Defeasance shall
not result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is
a party or by which the Company is bound;

                 (f)      In the case of any election under Section 8.2 or 8.3,
the Company shall have delivered to the Trustee an Officers' Certificate
stating that the deposit made by the Company pursuant to its election under
Section 8.2 or 8.3 was not made by the Company with the intent of preferring
the Holders over other creditors of the Company or with the intent of
defeating, hindering, delaying or defrauding creditors of the Company or
others; and

                 (g)      The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for relating to either the Legal Defeasance under
Section 8.2 or the Covenant Defeasance under Section 8.3 (as the case may be)
have been complied with as contemplated by this Section 8.4.

SECTION  8.5     Deposited Money and U.S. Government Securities to be Held in
                 Trust; Other Miscellaneous Provisions.

         Subject to Section 8.6, all money and non-callable U.S. Government
Securities (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.5, the
"Trustee") pursuant to Section 8.4 in respect of the outstanding Securities
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company or a Subsidiary
Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the
Holders of such Securities of all sums due and to become due thereon in respect
of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable U.S.
Government Securities deposited pursuant to Section 8.4 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.





                                       48
<PAGE>   56
         Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the
Company's request any money or non-callable U.S. Government Securities held by
it as provided in Section 8.4 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.4(a)), are in excess of the amount thereof which would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION  8.6     Repayment to Company.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Security which is not subject to the last paragraph of
Section 8.5 and has remained unclaimed for one year after such principal, and
premium, if any, or interest has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Securities shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

SECTION  8.7     Reinstatement.

         If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or non-callable U.S. Government Securities in accordance with Section
8.2 or 8.3, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining, or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.2 or 8.3 until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 8.2 or 8.3, as
the case may be; provided, however, that, if the Company makes any payment of
principal of, premium, if any, or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held
by the Trustee or Paying Agent.

                                   ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS


SECTION  9.1     Without Consent of Holders.

         The Company, the Subsidiary Guarantors and the Trustee may amend or
supplement this Indenture or the Securities without notice to or consent of any
Holder:

                          (1)     to cure any ambiguity, defect or
                                  inconsistency;

                          (2)     to comply with Section 5.1;

                          (3)     to reflect the addition or release of any
                 Subsidiary Guarantor, as provided for by this Indenture;

                          (4)     to comply with any requirements of the SEC in
                 order to effect or maintain the qualification of this
                 Indenture under the TIA; or

                          (5)     to make any change that would provide any
                 additional benefit or rights to the Holders or that does not
                 adversely affect the rights of any Holder in any material
                 respect.

         Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board Resolution of the Company and of each Subsidiary
Guarantor authorizing the execution of any such supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 9.6, the
Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of any supplemental indenture authorized or permitted by the terms of
this Indenture and make any further appropriate agreements and stipulations
that may be therein contained.  After an amendment or waiver under this Section
becomes effective, the Company shall mail to the Holders of each Security
affected thereby a notice briefly describing the amendment or waiver.  Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

SECTION  9.2     With Consent of Holders.

         Except as provided below in this Section 9.2, the Company, the
Subsidiary Guarantors and the Trustee may amend this Indenture or the
Securities with the written consent (including consents obtained in connection
with a tender offer or exchange offer for Securities or a solicitation of
consents in respect of Securities, provided that in each case such offer or
solicitation is made to all Holders of then outstanding Securities on equal
terms) of the Holders of at least a majority of the principal amount of the
outstanding Securities.





                                       50
<PAGE>   58
         Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board Resolution of the Company and each Subsidiary Guarantor
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of the Holders as aforesaid,
and upon receipt by the Trustee of the Opinion of Counsel described in Section
9.6, the Trustee shall join with the Company and the Subsidiary Guarantors in
the execution of such supplemental indenture.

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

         The Holders of a majority of the principal amount of the outstanding
Securities may waive compliance in a particular instance by the Company or the
Subsidiary Guarantors with any provision of this Indenture or the Securities
(including waivers obtained in connection with a tender offer or exchange offer
for Securities or a solicitation of consents in respect of Securities, provided
that in each case such offer or solicitation is made to all Holders of the then
outstanding Securities on equal terms).  However, without the consent of each
Holder affected, an amendment or waiver under this Section may not:

                          (1)     reduce the percentage of principal amount of
                 Securities whose Holders must consent to an amendment,
                 supplement or waiver of any provision of this Indenture or the
                 Securities;

                          (2)     reduce the rate or change the time for
                 payment of interest, including default interest, on the
                 Securities;

                          (3)     reduce the principal amount of any Security
                 or change the Maturity Date of the Securities;

                          (4)     reduce the redemption price, including
                 premium, if any, payable upon the redemption of any Security
                 or change the time at which any Security may be redeemed;

                          (5)     waive a Default or Event of Default in the
                 payment of the principal of, premium, if any, or interest on
                 the Securities;

                          (6)     make any Security payable in money other than
                                  that stated in the Security;

                          (7)     impair the right to institute suit for the
                 enforcement of principal of, premium, if any, or principal on
                 any Security pursuant to Sections 6.7 or 6.8, except as
                 limited by Section 6.6; or





                                       51
<PAGE>   59
                          (8)     make any change in Section 6.4 or Section 6.7 
                 or in this sentence of this Section 9.2.

         The right of any Holder to participate in any consent required or
sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of
record of any Securities with respect to which such consent is required or
sought as of a date identified by the Trustee in a notice furnished to Holders
in accordance with the terms of this Indenture.

SECTION  9.3     Compliance with Trust Indenture Act.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with the TIA as then in effect.

SECTION  9.4     Revocation and Effect of Consents.

         A consent to an amendment, supplement or waiver by a Holder of a
Security shall bind the Holder and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security, even if notation of the consent is not made on any Security.
However, until an amendment, supplement or waiver becomes effective, any such
Holder or subsequent Holder may revoke the consent as to its Security or
portion of a Security.  For such revocation to be effective, the Trustee must
receive the notice of revocation before the date the amendment, supplement or
waiver becomes effective.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver.  If the Company elects to fix a record date for such purpose, the
record date shall be fixed at (i) the later of 30 days prior to the first
solicitation of such consent or the date of the most recent list of Holders
furnished to the Trustee prior to such solicitation pursuant to Section 2.5, or
(ii) such other date as the Company shall designate.  If a record date is
fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to
such amendment or waiver or to revoke any consent previously given, whether or
not such Persons continue to be Holders after such record date.  No consent
shall be valid or effective for more than 90 days after such record date unless
consent from the Holders of the principal amount of Securities required
hereunder for such amendment or waiver to be effective also shall have been
given and not revoked within such 90-day period.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder unless it makes a change described in any of clauses (i)
through (ix) of Section 9.2.  In that case the amendment, supplement or waiver
shall bind each Holder of a Security who has consented to it and





                                       52
<PAGE>   60
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security.

SECTION  9.5     Notation on or Exchange of Securities.

         If an amendment, supplement or waiver 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 about
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.

SECTION  9.6     Trustee Protected.

         The Trustee shall sign any amendment or supplement or waiver
authorized pursuant to this Article if the amendment or supplement or waiver
does not adversely affect the rights of the Trustee.  If it does adversely
affect the rights of the Trustee, the Trustee may but need not sign it.  In
signing such amendment or supplement or waiver the Trustee shall be entitled to
receive, and (subject to Article Seven) shall be fully protected in relying

                                   GUARANTEES


SECTION  10.1    Unconditional Guarantee.

         Each Subsidiary Guarantor hereby, jointly and severally,
unconditionally guarantees (such guarantee to be referred to herein as the
"Guarantee") to each Holder and to the Trustee the due and punctual payment of
the principal of, premium, if any, and interest on the Securities and all other
amounts due and payable under this Indenture and the Securities by the Company
whether at maturity, by acceleration, redemption, repurchase or otherwise,
including, without limitation, interest on the overdue principal of, premium,
if any, and interest on the Securities, to the extent lawful, all in accordance
with the terms hereof and thereof; subject, however, to the limitations set
forth in Section 10.5.

         Failing payment when due of any amount so guaranteed for whatever
reason, the Subsidiary Guarantors will be jointly and severally obligated to
pay the same immediately.  Each Subsidiary Guarantor hereby agrees that its
obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Securities or this Indenture, the absence
of any action to enforce the same, any waiver or consent by any Holder of the
Securities with respect to any provisions hereof or thereof, the recovery of
any judgment against the Company, any action to





                                       53
<PAGE>   61
enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company,
any right to require a proceeding first against the Company, protest, notice
and all demands whatsoever and covenants that this Guarantee will not be
discharged except by complete performance of the obligations contained in the
Securities, this Indenture and in this Guarantee.  If any Holder or the Trustee
is required by any court or otherwise to return to the Company, any Subsidiary
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or any Subsidiary Guarantor, any amount paid
by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.  Each Subsidiary Guarantor agrees it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby.  Each Subsidiary Guarantor further agrees that, as between
each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any acceleration of such obligations as provided in Article Six, such
obligations (whether or not due and payable) shall forthwith become due and
payable by each Subsidiary Guarantor for the purpose of this Guarantee.

SECTION  10.2    Subsidiary Guarantors May Consolidate, etc. on Certain Terms.

                 (a)      Subject to paragraph (b) of this Section 10.2, no
Subsidiary Guarantor may consolidate or merge with or into (whether or not such
Subsidiary Guarantor is the surviving entity or Person) another corporation,
entity or Person unless (i) the entity or Person formed by or surviving any
such consolidation or merger (if other than such Subsidiary Guarantor) assumes
all the obligations of such Subsidiary Guarantor pursuant to a supplemental
indenture, in a form reasonably satisfactory to the Trustee, under the
Securities and this Indenture and (ii) immediately after such transaction, no
Default or Event of Default exists.  In connection with any consolidation or
merger contemplated by this Section 10.2, the Company shall deliver to the
Trustee prior to the consummation of the proposed transaction an Officers'
Certificate to the foregoing effect and an Opinion of Counsel stating that the
proposed transaction and such supplemental indenture comply with this
Indenture.  This Section 10.2(a) will not prohibit a merger between Subsidiary
Guarantors or a merger between the Company and a Subsidiary Guarantor.

                 (b)      In the event of a sale or other disposition of all or
substantially all of the assets of any Subsidiary Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the
Capital Stock of such Subsidiary Guarantor, then such Subsidiary Guarantor (in
the event of a sale or other disposition, by way of such a merger,
consolidation or otherwise, of all of the Capital Stock of such Subsidiary
Guarantor) or the corporation acquiring the property (in the event of a sale or
other disposition of all or substantially all of the assets of such Subsidiary
Guarantor) will be released and relieved of any obligations under its
Guarantees.

SECTION  10.3    Addition of Subsidiary Guarantors.

                 (a)      If any Subsidiary of the Company guarantees any
Funded Indebtedness of the Company at any time subsequent to the Issue Date,
then the Company shall (i) cause the Securities to be equally and ratably
guaranteed by such Subsidiary, but only to the extent that the Securities are
not already guaranteed by such Subsidiary on reasonably comparable terms and
(ii) cause such Subsidiary to execute and deliver a supplemental indenture, in
a form reasonably satisfactory to the Trustee, evidencing its provision of a
guarantee pursuant to the terms hereof.

                 (b)      The Company agrees to cause each Subsidiary other
than a Foreign Subsidiary that shall become a Restricted Subsidiary after the
Issue Date to execute and deliver a supplemental indenture pursuant to which
such Restricted Subsidiary shall guarantee the payment of the Securities
pursuant to the terms hereof.

                 (c)      Any Person that was not a Subsidiary Guarantor on the
Issue Date may become a Guarantor by executing and delivering to the Trustee
(i) a supplemental indenture in form and substance satisfactory to the Trustee,
which subjects such Person to the provisions (including the representations and
warranties) of this Indenture as a Subsidiary Guarantor and (ii) an Opinion of
Counsel and Officers' Certificate to the effect that such supplemental
indenture has been duly authorized and executed by such Person and constitutes
the legal, valid, binding and enforceable obligation of such Person (subject to
such customary exceptions concerning creditors' rights and equitable principles
as may be acceptable to the Trustee in its discretion and provided that no
opinion need be rendered concerning the enforceability of the Guarantee).

SECTION  10.4    Release of a Subsidiary Guarantor.

                 (a)      If, at any time while the Securities remain
outstanding, none of the Company's then outstanding Pari Passu Indebtedness
(other than the Securities) is guaranteed by a Restricted Subsidiary, such
Restricted Subsidiary shall be released and relieved of its obligations under
its Guarantee (which shall be terminated and cease to have any force and
effect).  For purposes of this Section 10.4(a) only, other Pari Passu
Indebtedness shall not be deemed to be outstanding if, and as long as, all
conditions to defeasance thereof have been satisfied, pursuant to defeasance
provisions substantially similar to those set forth in Article Eight hereof.

                 (b)      Upon the sale or disposition of a Subsidiary
Guarantor (or substantially all of its assets), which is otherwise in
compliance with the terms of this Indenture, including but not limited to the
provisions of Section 10.2, or if a Subsidiary ceases to be a Restricted
Subsidiary, such Subsidiary shall be released and relieved of its obligations
under its Guarantee (which shall terminate and cease to have any force and
effect).  The Trustee shall deliver an appropriate instrument evidencing such
release upon receipt of a request by the Company accompanied by an Officers'
Certificate and an Opinion of Counsel certifying that such sale or other
disposition or cessation was made by the Company in accordance with the
provisions of this Indenture.





                                       55
<PAGE>   63
                 (c)      Any Subsidiary Guarantor not so released pursuant to
this Article Ten remains liable for the full amount of principal of and
interest on the Securities as provided in this Article Ten.

SECTION  10.5    Limitation of Subsidiary Guarantor's Liability.

         Each Subsidiary Guarantor, and by its acceptance hereof each Holder,
hereby confirms that it is the intention of all such parties that the guarantee
by such Subsidiary Guarantor pursuant to its Guarantee not constitute a
fraudulent transfer or conveyance for purposes of any federal or state law.  To
effectuate the foregoing intention, the Holders and each Subsidiary Guarantor
hereby irrevocably agree that the obligations of each Subsidiary Guarantor
under the Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Subsidiary
Guarantor and after giving effect to any collections from or payments made by
or on behalf of any other Subsidiary Guarantor in respect of the obligations of
such other Subsidiary Guarantor under its Guarantee or pursuant to Section
10.6, result in the obligations of such Subsidiary Guarantor under the
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal or state law.  This Section 10.5 is for the benefit of the creditors of
each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer
and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor
pursuant to a bank credit facility shall be deemed to have been incurred prior
to the incurrence by such Subsidiary Guarantor of its liability under the
Guarantee.

SECTION  10.6    Contribution.

         In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
"Funding Guarantor") under the Guarantee, such Funding Guarantor shall be
entitled to a contribution from each other Subsidiary Guarantor in a pro rata
amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including
the Funding Guarantor) for all payments, damages and expenses incurred by the
Funding Guarantor in discharging the Company's obligations with respect to the
Securities or any other Subsidiary Guarantor's obligations with respect to the
Guarantee.

SECTION  10.7    Execution and Delivery of Guarantee.

         To further evidence the Guarantees set forth in Section 10.1, each
Subsidiary Guarantor hereby agrees that a notation relating to such Guarantee,
in substantially the form of Exhibit A-1, shall be endorsed on each Security
authenticated and delivered by the Trustee and executed by either manual or
facsimile signature of one Officer of each Subsidiary Guarantor.

         Each of the Subsidiary Guarantors hereby agrees that its Guarantee set
forth in Section 10.1 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation relating to such Guarantee.





                                       56
<PAGE>   64
         If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Security no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, such Subsidiary
Guarantor's Guarantee of such Security shall be valid nevertheless.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Subsidiary Guarantor.

SECTION  10.8    Severability.

         In case any provision of this Guarantee shall be invalid, illegal or
unenforceable, that portion of such provision that is not invalid, illegal or
unenforceable shall remain in effect, and the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

                         CHESAPEAKE ENERGY CORPORATION

                    7 7/8% SERIES [A/B] SENIOR NOTE DUE 2004


                 1.       Interest.  Chesapeake Energy Corporation, an Oklahoma
corporation (the "Company"), promises to pay interest on the principal amount
of this Security at 7 7/8% per annum from the Issue Date until maturity.  The
Company will pay interest semiannually on March 15 and September 15 of each
year (each an "Interest Payment Date"), or if any such day is not a Business
Day, on the next succeeding Business Day.  Interest on the Securities will
accrue from the most recent Interest Payment Date on which interest has been
paid or, if no interest has been paid, from the Issue Date; provided, that if
there is no existing Default in the payment of interest, and if this Security
is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be September 15, 1997.  The Company shall pay interest on
overdue principal and premium, if any, from time to time on demand at a rate
equal to the interest rate on the Securities then in effect; it shall pay
interest on overdue installments of interest (without regard to any applicable
grace periods) from time to time on demand at the same rate to the extent
lawful.  Interest will be computed on the basis of a 360-day year of twelve
30-day months.  All references herein to interest shall include additional
interest, if any, payable as Liquidated Damages pursuant to the Registration
Rights Agreement.

                 2.       Method of Payment.  The Company will pay interest on
the Securities to the persons who are registered holders of Securities at the
close of business on the record date immediately preceding the Interest Payment
Date, even if such Securities are canceled after the record date and on or
before the Interest Payment Date. Holders must surrender Securities to the
Paying Agent to collect principal payments.  The Company will pay principal of,
premium, if any, and interest on the Securities in money of the United States
of America that at the time of payment is legal tender for payment of public
and private debts.  However, the Company may pay principal and interest by wire
transfer of Federal Funds, or interest by its check payable in such U.S. Legal
Tender.  The Company may deliver any such interest payment to the Paying Agent
or to a Holder at the Holder's registered address.  Notwithstanding the
foregoing, the Company shall pay or cause to be paid all amounts payable with
respect to Restricted Securities or non-DTC eligible Securities by wire
transfer of Federal funds to the account of the Holders of such Securities.  If
this Security is a Global Security, all payments in respect of this Security
will be made to the Depository or its nominee in immediately available funds in
accordance with customary procedures established from time to time by the
Depository.

                 3.       Paying Agent and Registrar.  Initially, the Trustee
will act as Paying Agent and Registrar.  The Company may change any Paying
Agent, Registrar or co-registrar without notice.  The Company or any of its
Subsidiaries may act as Paying Agent or Registrar.

                 4.       Indenture.  The Company issued the Securities under
an Indenture, dated as of March 15, 1997 (the "Indenture"), among the Company,
the Subsidiary Guarantors and the Trustee.  Capitalized terms herein are used
as defined in the Indenture unless otherwise defined herein.  The terms of the
Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code
Sections 77aaa-77bbbb) as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Securities are subject to
all such terms, and Holders are referred to the Indenture and such Act for a
complete statement of such terms.  The Securities are limited to $150,000,000
aggregate principal amount.

                 5.       Ranking and Guarantees.  The Securities are general
senior unsecured obligations of the Company.  The Company's obligation to pay
principal, premium, if any, and interest with respect to the Securities is
unconditionally guaranteed on a senior basis, jointly and severally, by the
Subsidiary Guarantors pursuant to Article Ten of the Indenture.  Certain
limitations to the obligations of the Subsidiary Guarantors are set forth in
further detail in the Indenture.

                 6.       Redemption at Make-Whole Price.  At any time, the
Company may, at its option, redeem all or any portion of the Securities at the
Make-Whole Price plus accrued and unpaid interest to the date of redemption.
Any redemption pursuant to this Paragraph 6 shall be made pursuant to the
provisions of Sections 3.1 through 3.6 of the Indenture.

                 7.       Notice of Redemption.  Notice of redemption will be
mailed to the Holder's registered address at least 30 days but not more than 60
days before the redemption date to each Holder of Securities to be redeemed.
If less than all Securities are to be redeemed, the Trustee shall select pro
rata, by lot or, if the Securities are listed on any securities exchange, by
any other method that the Trustee considers fair and appropriate and that
complies with the requirements of such exchange; the Securities to be redeemed
in multiples of $1,000; provided, however, that no Securities with a principal
amount of $1,000 or less will be redeemed in part.  Securities in denominations
larger than $1,000 may be redeemed in part.  On and after the redemption date,
interest ceases to accrue on Securities or portions of them called for
redemption (unless the Company shall default in the payment of the redemption
price or accrued interest).

                 8.       Restrictive Covenants.  The Indenture imposes certain
limitations on, among other things, the ability of the Company to merge or
consolidate with any other Person or sell, lease or otherwise transfer all or
substantially all of its properties or assets, the ability of the Company or
the Restricted Subsidiaries to incur encumbrances against certain property or
enter into certain sale and leaseback transactions, all subject to certain
limitations described in the Indenture.

                 9.       Denominations, Transfer, Exchange.  The Securities
shall be issued in global form or in accordance with Section 2.6(f) of the
Indenture, in definite registered form, without coupons in denominations of
$1,000 and whole multiples of $1,000.  A Holder may transfer or exchange
Securities in accordance with the Indenture.  The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not transfer or exchange any





                                      A-5
<PAGE>   76
Securities selected for redemption.  Also, it need not transfer or exchange any
Securities for a period of 15 days before a selection of Securities to be
redeemed.

                 10.      Persons Deemed Owners.  The registered Holder of a
Security may be treated as the owner of it for all purposes and neither the
Company, any Subsidiary Guarantor, the Trustee nor any Agent shall be affected
by notice to the contrary.

                 11.      Unclaimed Money.  If money for the payment of
principal or interest remains unclaimed for one year, the Trustee or Paying
Agent will pay the money back to the Company at its request.  After that, all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

                 12.      Amendment, Supplement, Waiver.  Subject to certain
exceptions, the Indenture or the Securities may be amended or supplemented with
the consent of the Holders of at least a majority of the outstanding principal
amount of the Securities, and any past default or noncompliance with any
provision may be waived with the consent of the Holders of a majority in
principal amount of the Securities.  Without the consent of any Holder, the
Company may amend or supplement the Indenture or the Securities to, among other
things, cure any ambiguity, defect or inconsistency or to make any change that
does not adversely affect the rights of any Holder.

                 13.      Successor Corporation.  When a successor corporation
assumes all the obligations of its predecessor under the Securities and the
Indenture, the predecessor corporation will be released from those obligations.

                 14.      Defaults and Remedies.  An event of default generally
is: default by the Company or any Subsidiary Guarantor for 30 days in payment
of interest on the Securities; default by the Company or any Subsidiary
Guarantor in payment of principal of, or premium, if any, on the Securities;
default by the Company or any Subsidiary Guarantor in the deposit of any
optional redemption payment when due and payable; defaults resulting in
acceleration prior to maturity of certain other Indebtedness or resulting from
payment defaults under certain other Indebtedness; failure by the Company or
any Subsidiary Guarantor for 45 days after notice to comply with any of its
other agreements in the Indenture; certain final judgments against the Company
or Subsidiaries; a failure of any Guarantee of a Subsidiary Guarantor to be in
full force and effect or denial by any Subsidiary Guarantor of its obligations
with respect thereto; and certain events of bankruptcy or insolvency.  Subject
to certain limitations in the Indenture, if an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Securities may declare all the Securities to be due and
payable immediately, except that in the case of an Event of Default arising
from certain events of bankruptcy, insolvency or reorganization relating to the
Company, all outstanding Securities shall become due and payable immediately
without further action or notice.  Holders may not enforce the Indenture or the
Securities except as provided in the Indenture.  The Trustee may require
indemnity satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations, Holders of a majority in principal





                                      A-6
<PAGE>   77
amount of the Securities may direct the Trustee in its exercise of any trust or
power.  The Company must furnish an annual compliance certificate to the
Trustee.

                 15.      Trustee Dealings with Company and Subsidiary
Guarantors.  The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company, the Subsidiary Guarantors or their respective Subsidiaries or
Affiliates with the same rights it would have if it were not Trustee.

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

                 17.      Authentication.  This Security shall not be valid
until the Trustee or an authenticating agent signs the certificate of
authentication on the other side of this Security.

                 18.      Abbreviations.  Customary abbreviations may be used
in the name of a Holder or an assignee, such as: TEN COM (=tenants in common),
TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of
survivorship and not as tenants in common), CUST (=Custodian), and U/G/M/A
(=Uniform Gifts to Minors Act).

                 19.      CUSIP Numbers.  Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company will cause CUSIP numbers to be printed on the Securities as a
convenience to Holders of the Securities.  No representation is made as to the
accuracy of such numbers as printed on the Securities and reliance may be
placed only on the other identification numbers printed hereon.

and without charge a copy of the Indenture.  Requests may be made to:

Attention:

Ladies and Gentlemen:

         In connection with our proposed purchase of $_________ aggregate
principal amount of 7 7/8% Senior Notes due 2004 (the "Notes") of Chesapeake
Energy Corporation (the "Company"), we confirm that:

                 (i)      we are an "institutional accredited investor" within
         the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities
         Act of 1933, as amended (the "Securities Act") (an "Institutional
         Accredited Investor"), or any entity in which all of the equity owners
         are Institutional Accredited Investors;

                 (ii)     any purchase of Notes by us will be for our own
         account or for the account of one or more other Institutional
         Accredited Investors as to which we exercise sole investment
         discretion;

                 (iii)    in the event that we purchase any Notes, we will
         acquire such Notes having a minimum purchase price of at least
         $100,000 for our own account and for each separate account for which
         we exercise sole investment discretion;

                 (iv)     we have such knowledge and experience in financial
         and business matters that we are capable of evaluating the merits and
         risks of purchasing Notes and we





                                      B-1
<PAGE>   82
         and any accounts for which we are acting are able to bear the economic
         risks of our or their investment;

                 (v)      we are not acquiring the Notes with a view to any
         distribution thereof in a transaction that would violate the
         Securities Act or the securities laws of any State of the United
         States or any other applicable jurisdiction; provided that the
         disposition of our property and the property of any accounts for which
         we are acting as shall remain at all times within our control; and

                 (vi)     we have received a copy of the Offering Memorandum
         and acknowledge that we have had access to such financial and other
         information, and have been afforded the opportunity to ask such
         questions of representatives of the Company and receive answers
         thereto, as we deem necessary in connection with our decision to
         purchase Notes.

         We understand that the Notes are being offered in a transaction not
involving any public offering in the United States within the meaning of the
Securities Act and that the Notes have not been registered under the Securities
Act, and we agree, on our own behalf and on behalf of each account for which we
acquire any Notes, that if we should sell or otherwise transfer any Notes prior
to the date which is three years  (or such shorter period set forth in Rule
144(k) under the Securities Act, as such provision may be amended) after the
original issuance of the Notes, we will do so only (a) to the Company or any of
its subsidiaries, (b) inside the United States in accordance with Rule 144A
under the Securities Act to a "qualified institutional buyer" (as defined in
Rule 144A under the Securities Act), (c) inside the United States to an
Institutional accredited Investor that, prior to such transfer, furnishes (or
has furnished on its behalf by a U.S. broker-dealer) to the Trustee, a signed
letter contained certain representations and agreements relating to the
restrictions on transfer of the Notes (the form of which letter can be obtained
from the applicable Trustee), (d) outside the United States in accordance with
Regulation S under the Securities Act, (e) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if available), or
(f) pursuant to an effective registration statement under the Securities Act.

         We understand that the registrar will not be required to accept for
registration of transfer any Notes, except upon presentation of evidence
satisfactory to the Company that the foregoing restrictions on transfer have
been complied with.  We understand that, on any proposed resale of any Notes,
we will be required to furnish to the Trustee and the Company such
certification, legal opinions and other information as the Trustee and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions.  We further understand that the Notes purchased by
us will bear a legend reflecting the substance of this paragraph.  We further
agree to provide to any person acquiring any of the Notes from us a notice
advising such person that resales of the Notes are restricted as stated herein.

         We acknowledge that you, the Company and others will rely upon our
confirmation, acknowledgments and agreements set forth herein, and agree to
notify you promptly in writing if any of our representations or warranties
herein cease to be accurate and complete.

SECTION  1.1     Definitions.

         "Adjusted Consolidated Net Tangible Assets" means, without
duplication, as of the date of determination, (a) the sum of (i) discounted
future net revenue from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines before any
state or federal income taxes, as estimated by independent petroleum engineers
in a reserve report prepared as of the end of the Company's most recently
completed fiscal year, as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of
the Company and its Restricted Subsidiaries attributable to any acquisition
consummated since the date of such year-end reserve report, and (B) estimated
oil and gas reserves of the Company and its Restricted Subsidiaries
attributable to extensions, discoveries and other additions and upward
revisions of estimates of proved oil and gas reserves due to exploration,
development or exploitation, production or other activities conducted or
otherwise occurring since the date of such year-end reserve report, which, in
the case of sub-clauses (A) and (B), would, in accordance with standard
industry practice, result in such increases as calculated in accordance with
SEC guidelines (utilizing the prices utilized in such year-end reserve report),
and decreased by, as of the date of determination, the discounted future net
revenue of (C) estimated proved oil and gas reserves of the Company and its
Restricted Subsidiaries produced or disposed of since the date of such year-end
reserve report and (D) reductions in the estimated oil and gas reserves of the
Company and its Restricted Subsidiaries since the date of such year-end reserve
report attributable to downward revisions of estimates of proved oil and gas
reserves due to exploration, development or exploitation, production or other
activities conducted or otherwise occurring since the date of such year-end
reserve report which, in the case of sub-clauses (C) and (D), would, in
accordance with standard industry practice, result in such decreases as
calculated in accordance with SEC guidelines (utilizing the prices utilized in
such year-end reserve report); provided that, in the case of each of the
determinations made pursuant to clauses (A) through (D), such increases and
decreases shall be as estimated by the Company's engineers, (ii) the
capitalized costs that are attributable to oil and gas properties of the
Company and its Restricted Subsidiaries to which no proved oil  and gas
reserves are attributable, based on the Company's books and records as of a
date no earlier than the date of the Company's latest annual or quarterly
financial statements, (iii) the Net Working Capital on a date
<PAGE>   9
no earlier than the date of the Company's latest annual or quarterly financial
statements and (iv) the greater of (I) the net book value on a date no earlier
than the date of the Company's latest annual or quarterly financial statements
and (II) the appraised value, as estimated by independent appraisers, of other
tangible assets (including Investments in unconsolidated Subsidiaries) of the
Company and its Restricted Subsidiaries, as of a date no earlier than the date
of the Company's latest audited financial statements, minus (b) the sum of (i)
minority interests, (ii) any gas balancing liabilities of the Company and its
Restricted Subsidiaries reflected in the Company's latest annual or quarterly
financial statements, (iii) the discounted future net revenue, calculated in
accordance with SEC guidelines (utilizing the prices utilized in the Company's
year-end reserve report), attributable to reserves which are required to be
delivered to third parties to fully satisfy the obligations of the Company and
its Restricted Subsidiaries with respect to Volumetric Production Payments on
the schedules specified with respect thereto, (iv) the discounted future net
revenue, calculated in accordance with SEC guidelines, attributable to reserves
subject to Dollar-Denominated Production Payments which, based on the estimates
of production included in determining the discounted future net revenue
specified in (a) (i) above (utilizing the same prices utilized in the Company's
year-end reserve report), would be necessary to fully satisfy the payment
obligations of the Company and its Restricted Subsidiaries with respect to
Dollar-Denominated Production Payments on the schedules specified with respect
thereto and (v) the discounted future net revenue, calculated in accordance
with SEC guidelines (utilizing the same prices utilized in the Company's
year-end reserve report), attributable to reserves subject to participation
interests, overriding royalty interests or other interests of third parties,
pursuant to participation, partnership, vendor financing or other agreements
then in effect, or which otherwise are required to be delivered to third
parties.  If the Company changes its method of accounting from the full cost

debts (after giving effect to all other fixed and contingent liabilities

<PAGE>   21
Securities offered and sold in their initial distribution in reliance on
Regulation S may be initially issued in the form of temporary Global Securities
in fully registered form without interest coupons, substantially in the form of
Exhibit A, with such applicable legends as are provided for in Exhibit A
hereto.  Such temporary Global Securities may be registered in the name of the
Depository or its nominee and deposited with the Trustee, as custodian for the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided, for credit by the Depository to the respective accounts
of the beneficial owners of the Securities represented thereby (or such other
accounts as they may direct), provided that upon such deposit all such
Securities shall be credited to or through accounts maintained at the
Depository by or on behalf of Euroclear or CEDEL.  Until such time as the
Restricted Period (as defined below) shall have expired, any such temporary
Global Securities, together with their Successor Securities which are Global
Securities other than the Restricted Global Security, shall each be referred to
herein as a "Temporary Regulation S Global Security."  After such time as the
Restricted Period shall have expired and the certifications referred to in the
next succeeding paragraph shall have been provided, interests in such Temporary
Regulation S Global Securities shall be exchanged for interests in like Global
Securities, each referred to herein collectively as a "Permanent Regulation S
Global Security," substantially in the form of Security set forth in Exhibit A,
with such applicable legends as are provided for in Exhibit A.  Such Permanent
Regulation S Global Securities shall be registered in the name of the
Depository or its nominee and deposited with the Trustee, as custodian for the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided, for credit to the respective accounts of the beneficial
owners of the Securities represented thereby (or such other accounts as they
may direct).  The aggregate principal amount of the Temporary Regulation S
Global Security or the Permanent Regulation S Global Security may be increased
or decreased from time to time by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided.  As used
herein, the term "Restricted Period" means the period of 40 days commencing on
the day after the latest of (a) the day on which the Securities are first
offered to persons other than distributors (as defined in Regulation S) in
reliance on Regulation S and (b) the Issue Date.

         Interests in a Temporary Regulation S Global Security may be exchanged
for interests in a Permanent Regulation S Global Security only after (a) the
expiration of the Restricted Period, (b) delivery by a beneficial owner of an
interest therein to Euroclear or CEDEL of a written certification (an "Owner
Securities Certification") substantially in the form of Exhibit C hereto, and
(c) upon delivery by Euroclear or CEDEL to the Trustee of a written
certification (a "Depository Securities Certification") substantially in the
form attached hereto as Exhibit D.  Upon satisfaction of such conditions, the
Trustee will exchange the portion of the Temporary Regulation S Global Security
covered by such certification for interests in a Permanent Regulation S Global
Security.  The delivery by such Holder of a beneficial interest in such
Temporary Regulation S Global Security of such certification shall constitute
an irrevocable instruction by such holder to Euroclear or CEDEL, as the case
may be, to exchange such Holder's beneficial interest in the Temporary
Regulation S Global Security for a beneficial interest in the Permanent
Regulation S Global Security upon the expiration of the Restricted Period in
accordance with the next succeeding paragraph.

         Upon:

<PAGE>   22
                          (i)     the expiration of the Restricted Period;

                          (ii)    receipt by Euroclear or CEDEL, as the case
         may be, of Owner Securities Certifications described in the
         preceding paragraph;

                          (iii)   receipt by the Depository of:

                          (1)     written instructions given in accordance with
                 the Applicable Procedures from an Agent Member directing the
                 Depository to credit or cause to be credited to a specified
                 Agent Member's account a beneficial interest in a Permanent
                 Regulation S Global Security in a principal amount equal to
                 that of the beneficial interest in a corresponding Temporary
                 Regulation S Global Security for which the necessary
                 certifications have been delivered; and

                          (2)     a written order given in accordance with the
                 Applicable Procedures containing information regarding the
                 account of the Agent Member, and the Euroclear or CEDEL
                 account for which such Agent Member's account is held, to be
                 credited with, and the account of the Agent Member to be
                 debited for, such beneficial interest; and

                          (iv)    receipt by the Trustee of notification from
         the Depository of the transactions described in (iii) above and from
         Euroclear or CEDEL, as the case may be, of Depository Securities
         Certifications,

the Trustee, as Registrar (as defined below), shall instruct the Depository to
reduce the principal amount of such Temporary Regulation S Global Security and
to increase the principal amount of such Permanent Regulation S Global
Security, by the principal amount of the beneficial interest in such Temporary
Regulation S Global Security to be so transferred, and to credit or cause to be
credited to the account of the person specified in such instructions a
beneficial interest in such Permanent Regulation S Global Security having a
principal amount equal to the amount by which the principal amount of such
Temporary Regulation S Global Security was reduced upon such transfer.

         Securities offered and sold in their initial distribution in reliance
on Rule 144A under the Securities Act and other than in reliance on Rule 144A
under the Securities Act or Regulation S shall be issued in the form of one or
more Global Securities (collectively, and, together with their Successor
Securities, the "Restricted Global Security") in fully registered form without
interest coupons, substantially in the form of Security set forth in Exhibit A
hereto, with such applicable legends as are provided for in Exhibit A except as
otherwise permitted herein.  Such Restricted Global Security shall be
registered in the name of the Depository or its nominee and deposited with the
Trustee, as custodian for the Depository, duly executed by the Company and
authenticated by the Trustee as hereinafter provided, for credit by the
Depository to the respective accounts of beneficial owners of the securities
represented thereby (or such other accounts as they may direct).





                                       15
<PAGE>   23
The aggregate principal amount of the Restricted Global Security may be
increased or decreased from time to time by adjustments made on the records of
the Trustee, as custodian for the Depository, in connection with a
corresponding decrease or increase in the aggregate principal amount of the
Temporary Regulation S Global Security or the Permanent Regulation S Global
Security, as hereinafter provided.

SECTION  2.2     Execution and Authentication.

         Two Officers of the Company shall sign the Securities on behalf of the
Company, and one Officer of each Subsidiary Guarantor shall sign the notation
on the Securities relating to the Guarantee of such Subsidiary Guarantor on
behalf of such Subsidiary Guarantor, in each case by manual or facsimile
signature.  The Company's seal shall be reproduced on the Securities.

         If an Officer of the Company or any Subsidiary Guarantor whose
signature is on a Security no longer holds that office at the time the Security
is authenticated, the Security shall be valid nevertheless.

         A Security shall not be valid until the Trustee or an authenticating
agent 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 or an authenticating agent shall authenticate Securities
for original issue in the aggregate principal amount of $150,000,000 upon a
written order of the Company signed by two Officers of the Company.  The
aggregate principal amount of Securities outstanding at any time may not exceed
$150,000,000.

         Series B Notes may be issued only in exchange for a like principal
amount of Series A Notes pursuant to an Exchange Offer.

         The principal and interest on Book-Entry Securities shall be payable
to the Depository or its nominee, as the case may be, as the sole registered
owner and the sole holder of the Book-Entry Securities represented thereby.
The principal and interest on Securities in certificated form shall be payable
at the office of the Paying Agent.

         The Trustee may appoint an authenticating agent to authenticate
Securities.  An authenticating agent may authenticate Securities whenever the
Trustee may do so except on original issuance.  Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent.  An authenticating agent has the same rights as an Agent to deal with
the Company or its Affiliates.

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





                                       16
<PAGE>   24
If the Securities are to be issued in the form of one or more Global
Securities, then the Company shall execute and the Trustee shall authenticate
and deliver one or more Global Securities that shall represent and shall be in
minimum denominations of $1,000.

SECTION  2.3     Registrar and Paying Agent.

         The Company shall maintain an office or agency where the 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").  The Registrar shall keep a register of the Securities and of
their transfer and exchange.  Where the Trustee is acting as or has been
appointed Registrar and/or Paying Agent, the Company may appoint one or more
co- registrars and one or more additional paying agents with the prior consent
of the Trustee, whose consent shall not be unreasonably withheld.  The term
"Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture.  Such agency agreement shall provide for
reasonable compensation for such services.  The agreement shall implement the
provisions of this Indenture that relate to such Agent.  The Company shall
notify the Trustee of the name and address of any such Agent and shall furnish
the Trustee with an executed counterpart of any such agency agreement.  If the
Company fails to maintain or act as Registrar or Paying Agent, the Trustee
shall act as such and shall be duly compensated therefor.

         The Registrar or a co-registrar and a Paying Agent shall be maintained
by the Company in the Borough of Manhattan, the City of New York.  The Company
initially designates the Trustee as the Registrar and Paying Agent.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Securities Custodian with respect to the Global
Securities.

SECTION  2.4     Paying Agent to Hold Money in Trust.

         The Company shall require each Paying Agent other than the Trustee to
hold in trust for the benefit of Holders or the Trustee all money held by such
Paying Agent for the payment of principal of, premium, if any, or interest on
the Securities (whether such money shall have been paid to it by the Company or
any Subsidiary Guarantor), and to notify the Trustee of any Default by the
Company or any Subsidiary Guarantor in making any such payment.  While any such
Default continues, the Trustee may require the Paying Agent to pay all money
held by it to the Trustee.  Except as provided in the immediately preceding
sentence, the Company at any time may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed and, if the
Company requires such payment, the Company shall give prior notice to the
Trustee and provide appropriate money transfer instructions to the Paying
Agent.  Upon such payment over to the Trustee and accounting for any funds
disbursed, such Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money.  If the Company or a Subsidiary acts
as Paying Agent,





                                       17
<PAGE>   25
it shall segregate and hold as separate trust funds for the benefit of the
Holders all money held by it as Paying Agent.

SECTION  2.5     Holder Lists.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders and shall otherwise comply with TIA Section 312(a).  If the Trustee is
not the Registrar, the Company shall furnish or cause to be furnished to the
Trustee at least ten Business Days prior to each semiannual 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, and the Company shall otherwise comply with TIA
Section 312(a).

SECTION  2.6     Transfer and Exchange.

                 (a)      Beneficial interests in a Global Security may,
subject to the restrictions on the transferability of the Securities and upon
delivery of a certificate in the form of Exhibit B hereto be exchanged for
certificated Securities upon request but only upon at least 20 days' prior
written notice given to the Trustee by or on behalf of the Depository (in
accordance with the Depository's customary procedures) and will bear the
applicable legends set forth in Exhibit A hereto.

                 (b)      If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depository or its nominee to the Trustee, as Registrar, for exchange or
cancellation as provided in this Article II.  If any Global Security is to be
exchanged for other Securities or cancelled in part, or if another Security is
to be exchanged in whole or in part for a beneficial interest in any Global
Security, such Global Security shall be so surrendered for exchange or
cancellation as provided in this Article II or, if the Trustee is acting as
custodian for the Depository or its nominee (or is party to a similar
arrangement) with respect to such Global Security, the principal amount thereof
shall be reduced or increased by an amount equal to the portion thereof to be
so exchanged or cancelled, or the principal amount of such other Security to be
so exchanged for a beneficial interest therein, as the case may be, in each
case by means of an appropriate adjustment made on the records of the Trustee,
whereupon the Trustee, in accordance with the Applicable Procedures, shall
instruct the Depository or its authorized representatives to make a
corresponding adjustment to its records (including by crediting or debiting any
Agent Member's account as necessary to reflect any transfer or exchange of a
beneficial interest).  Upon any such surrender or adjustment of a Global
Security, the Trustee shall, subject to this Article II, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered in such names as may
be directed by, the Depository or its authorized representative.  Upon the
request of the Trustee in connection with the occurrence of any of the events
specified in the preceding paragraph or in clause (r) below, the Company shall
promptly make available to the Trustee a reasonable supply of Securities that
are not in the form of Global Securities.  The Trustee shall be entitled to
rely upon any order, direction or request of the





                                       18
<PAGE>   26
Depository or its authorized representative which is given or made pursuant to
this Article II if such order, direction or request is given or made in
accordance with the Applicable Procedures.

                 (c)      Subject to the provisions in the legends required by
this Indenture, the registered Holder may grant proxies and otherwise authorize
any Person, including Agent Members and Persons who may hold interests in Agent
Members to take any action that such Holder is entitled to take under this
Indenture.

                 (d)      Neither Agent Members nor any other Person on whose
behalf Agent Members may act shall have any rights under this Indenture with
respect to any Global Security held on their behalf by the Depository or under
the Global Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever.  Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent
of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of customary practice
governing the exercise of the rights of a Holder of any Security.  With respect
to any Global Security deposited with the Trustee as custodian for the
Depository for credit to their respective accounts (or to such other accounts
as they may direct) at Euroclear or CEDEL, the provisions of the "Operating
Procedures of the Euroclear System" and the "Terms and Conditions Governing Use
of Euroclear," and the "Management Regulations" and "Instructions to
Participants" of CEDEL, respectively, shall be applicable to such Global
Security.

                 (e)      Upon presentation for transfer and exchange of any
Security at the office of the Trustee, as Registrar, located in The City of New
York, accompanied by a written instrument of transfer or exchange in the form
approved by the Company (it being understood that, until notice to the contrary
is given to holders of Securities, the Company shall be deemed to have approved
the form of instrument of transfer or exchange, if any, printed on any
Security), executed by the registered Holder, in person or by such Holder's
attorney thereunto duly authorized in writing, and upon compliance with this
Section 2.6, such Security shall be transferred upon the Register, and a new
Security shall be authenticated and issued in the name of the transferee.
Notwithstanding any provision to the contrary herein or in the Securities,
transfers of a Global Security, in whole or in part, and transfers of interests
therein of the kind described in this Section 2.6, shall only be made in
accordance with this Section 2.6.  Transfers and exchanges subject to this
Section 2.6 shall also be subject to the other provisions of this Indenture
that are not inconsistent with this Section 2.6.

                 (f)      General.  A Global Security may not be transferred,
in whole or in part, to any Person other than the Depository or a nominee
thereof, and no such transfer to any such other Person may be registered;
provided, however, that this clause (f) shall not prohibit any transfer of a
Security that is issued in exchange for a Global Security but is not itself a
Global Security.  No transfer of a Security to any Person shall be effective
under this Indenture or the Securities unless and until such Security has been
registered in the name of such Person.  Nothing in this clause (f) shall
prohibit or





                                       19
<PAGE>   27
render ineffective any transfer of a beneficial interest in a Global Security
effected in accordance with the other provisions of this Section 2.6.

                 (g)      Temporary Regulation S Global Security.  If the
holder of a beneficial interest  in a Temporary Regulation S Global Security
wishes at any time to transfer such interest to a Person who wishes to take
delivery thereof in the form of a beneficial interest in such Temporary
Regulation S Global Security, such transfer may be effected, subject to the
rules and procedures of the Depository, Euroclear and CEDEL, in each case to
the extent applicable and as in effect from time to time (the "Applicable
Procedures"), only in accordance with this clause (g).  Upon delivery (i) by a
beneficial owner of an interest in a Temporary Regulation S Global Security to
Euroclear or CEDEL, as the case may be, of an Owner Securities Certification,
(ii) by the transferee of such beneficial interest in the Temporary Regulation
S Global Security to Euroclear or CEDEL, as the case may be, of a written
certification (a "Transferee Securities Certification") substantially in the
form of Exhibit E hereto and (iii) by Euroclear or CEDEL, as the case may be,
to the Trustee, as Registrar, of a Depository Securities Certification, the
Trustee may direct either Euroclear or CEDEL, as the case may be, to reflect on
its records the transfer of a beneficial interest in the Temporary Regulation S
Global Security from the beneficial owner providing the Owner Securities
Certification to the Person providing the Transferee Securities Certification.

                 (h)      Restricted Global Security to Temporary Regulation S
Global Security.  If the holder of a beneficial interest in the Restricted
Global Security wishes at any time to transfer such interest to a Person who
wishes to take delivery thereof in the form of a beneficial interest in the
Temporary Regulation S Global Security, such transfer may be effected, subject
to the Applicable Procedures, only in accordance with the provisions of this
clause (h) and clause (n) below.  Upon receipt by the Trustee, as Registrar, of
(A) written instructions given by or on behalf of the Depository in accordance
with the Applicable Procedures directing the Trustee to credit or cause to be
credited to a specified Agent Member's account a beneficial interest in the
Temporary Regulation S Global Security in a specified principal amount and to
cause to be debited from another specified Agent Member's account a beneficial
interest in the Restricted Global Security in an equal principal amount and (B)
a certificate in substantially the form set forth in Exhibit F hereto signed by
or on behalf of the holder of such beneficial interest in the Restricted Global
Security, the Trustee, as Registrar, shall, subject to clause (n) below, reduce
the principal amount of the Restricted Global Security, and increase the
principal amount of the Temporary Regulation S Global Security by such
specified principal amount.

                 (i)      Restricted Global Security to Permanent Regulation S
Global Security.  If the holder of a beneficial interest in the Restricted
Global Security wishes at any time to transfer such interest to a Person who
wishes to take delivery thereof in the form of a beneficial interest in the
Permanent Regulation S Global Security, such transfer may be effected, subject
to the Applicable Procedures, only in accordance with this clause (i).  Upon
receipt by the Trustee, as Registrar, of (A) written instructions given by or
on behalf of the Depository in accordance with the Applicable Procedures
directing the Trustee to credit or cause to be credited to a specified Agent
Member's account a beneficial interest in the Permanent Regulation S Global
Security in a specified principal





                                       20
<PAGE>   28
amount and to cause to be debited from another specified Agent Member's account
a beneficial interest in the Restricted Global Security in an equal principal
amount and (B) a certificate in substantially the form set forth in Exhibit G
hereto signed by or on behalf of the holder of such beneficial interest in the
Restricted Global Security, the Trustee, as Registrar, shall reduce the
principal amount of a Restricted Global Security, and increase the principal
amount of the Permanent Regulation S Global Security by such specified
principal amount.

                 (j)      Temporary Regulation S Global Security or Permanent
Regulation S Global Security to Restricted Global Security.  If the holder of a
beneficial interest in the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security at any time, wishes to transfer such
interest to a Person who wishes to take delivery thereof in the form of a
beneficial interest in the Restricted Global Security, such transfer may be
effected, subject to the Applicable Procedures, only in accordance with this
clause (j) and clause (n) below; provided, that with respect to any transfer of
a beneficial interest in a Temporary Regulation S Global Security, the
transferor and Euroclear or CEDEL, as the case may be, must have previously
delivered an Owner Securities Certification and a Depository Securities
Certification respectively, with respect to such beneficial interest.  Upon
receipt by the Trustee, as Registrar, of (A) written instructions given by or
on behalf of the Depository in accordance with the Applicable Procedures
directing the Trustee to credit or cause to be credited, to a specified Agent
Member's account a beneficial interest in the Restricted Global Security in a
specified principal amount and to cause to be debited from another specified
Agent Member's account a beneficial interest in the Temporary Regulation S
Global Security or the Permanent Regulation S Global Security, as the case may
be, in an equal principal amount and (B) a certificate in substantially the
form set forth in Exhibit H signed by or on behalf of the holder of such
beneficial interest in the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security, as the case may be, the Trustee, as
Security Registrar, shall, subject to clause (n) below, reduce the principal
amount of such Temporary Regulation S Global Security or Permanent Regulation S
Global Security, as the case may be, and increase the principal amount of the
Restricted Global Security by such specified principal amount.

                 (k)      Non-Global Restricted Security to Restricted Global
Security.  If the holder of a Restricted Security (other than a Global
Security) wishes at any time to transfer all or any portion of such Security to
a Person who wishes to take delivery thereof in the form of a beneficial
interest in the Restricted Global Security, the Temporary Regulation S Global
Security or the Permanent Regulation S Global Security, such transfer may be
effected, subject to the Applicable Procedures, only in accordance with this
clause (k) and clause (n) below.  Upon receipt by the Trustee, as Registrar, of
(A) such Security and written instructions given by or on behalf of such Holder
as provided in this Section 2.6 directing the Trustee to credit or cause to be
credited to a specified Agent Member's account a beneficial interest in the
Restricted Global Security, the Temporary Regulation S Global Security or the
Permanent Regulation S Global Security, as the case may be, in a specified
principal amount equal to the principal amount of the Restricted Security (or
portion thereof) to be so transferred, and (B) an appropriately completed
certificate substantially in the form set forth in Exhibit I-1 hereto, if the
specified account is to be credited with a beneficial interest in the
Restricted Global Security, or Exhibit I-2 herein, if the specified account is
to be





                                       21
<PAGE>   29
credited with a beneficial interest in the Temporary Regulation S Global
Security or the Permanent Regulation S Global Security, signed by or on behalf
of such Holder, then the Trustee, as Registrar, shall, subject to clause (n)
below, cancel such Restricted Security (and issue a new Security in respect of
any untransferred portion thereof) as provided in this Section 2.6 and increase
the principal amount of the Restricted Global Security, Temporary Regulation S
Global Security or Permanent Regulation S Global Security, as the case may be,
by the specified principal amount.

                 (l)      Non-Global Permanent Regulation S Security to
Restricted Global Security or Permanent Regulation S Global Security.  If the
Holder of a Permanent Regulation S Security (other than a Global Security)
wishes at any time to transfer all or any portion of such Security to a Person
who wishes to take delivery thereof in the form of a beneficial interest in the
Restricted Global Security or the Permanent Regulation S Global Security, as
the case may be, such transfer may be effected only in accordance with this
clause (1) and subject to the Applicable Procedures.  Upon receipt by the
Trustee, as Registrar, of (A) such Security and instructions given by or on
behalf of such Holder as provided in this Section 2.6 directing the Trustee to
credit or cause to be credited to a specified Agent Member's account a
beneficial interest in the Restricted Global Security or the Permanent
Regulation S Global Security, as the case may be, in a principal amount equal
to the principal amount of the Security (or portion thereof) to be so
transferred, and (B) (i) with respect to a transfer which is to be delivered in
the form of a beneficial interest in the Restricted Global Security, a
certificate in substantially the form set forth in Exhibit J-1 hereto, signed
by or on behalf of such Holder, and (ii) with respect to a transfer which is to
be delivered in the form of a beneficial interest in the Permanent Regulation S
Global Security, a certificate in substantially the form set forth in Exhibit
J-2 hereto, signed by or on behalf of such Holder, then the Trustee, as
Registrar, shall, subject to clause (q) below, cancel such Security (and issue
a new Security in respect of any untransferred portion thereof) as provided in
this Section 2.6 and increase the principal amount of the Restricted Global
Security, or the Permanent Regulation S Global Security, as the case may be, by
the specified principal.

                 (m)      Other Exchanges.  Securities that are not Global
Securities may be exchanged (on transfer or otherwise) for Securities that are
not Global Securities or for beneficial interests in a Global Security (if any
is then outstanding) only in accordance with such procedures, which shall be
substantially consistent with the provisions of clauses (f) through (l) above
(including the certification requirements intended to insure that transfers of
beneficial interests in a Global Security comply with Rule 144A under the
Securities Act or Regulation S, as the case may be) and any Applicable
Procedures, as may from time to time be adopted by the Company and the Trustee.

                 (n)      Interests in Temporary Regulation S Global Security
to be Held Through Euroclear or CEDEL.  Until the later of the expiration of
the Restricted Period and the provision of the Owner Securities Certification
and the Depository Securities Certification, beneficial interests in any
Temporary Regulation S Global Security may be held only in or through accounts
maintained at the Depository by Euroclear or CEDEL (or by Agent Members acting
for the account thereof).





                                       22
<PAGE>   30
                 (o)      When Securities in certificated form are presented to
the Registrar with a request to register the transfer of such Securities or to
exchange such Securities for an equal principal amount of Securities of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing.  To permit registrations of
transfers and exchanges, the Company shall execute and the Trustee shall
authenticate Securities at the Registrar's request.  No service charge shall be
made for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer taxes or
similar governmental charge payable upon exchanges or transfers pursuant to
Sections 2.2, 2.10, 3.7 or 9.5).  The Registrar shall not be required to
register the transfer of or exchange of any Security (i) during a period
beginning at the opening of business 15 days before the mailing of a notice of
redemption of Securities and ending at the close of business on the day of such
mailing and (ii) selected for redemption in whole or in part pursuant to
Article Three, except the unredeemed portion of any Security being redeemed in
part.

                 (p)      If a Series A Note is a Restricted Security in
certificated form, then as provided in this Indenture and subject to the
limitations herein set forth, the Holder, provided it is a Qualified
Institutional Buyer or an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act), may exchange such
Security for a Book-Entry Security by instructing the Trustee (by completing
the Transferee Certificate in the form of Exhibit B hereto) to arrange for such
Series A Note to be represented by a beneficial interest in a Global Security
in accordance with the customary procedures of the Depository.

                 (q)      Upon any exchange provided for in Section 2.6(a), the
Company shall execute and the Trustee shall authenticate, and deliver to the
person specified by the Depository a new Series A Note or Notes registered in
such names and in such authorized denominations as the Depository, pursuant to
the instructions of the beneficial owner of the Securities requesting the
exchange, shall instruct the Trustee.  Thereupon, the beneficial ownership of
such Global Security shown on the records maintained by the Depository or its
nominee shall be reduced by the amounts so exchanged and an appropriate
endorsement be made by and on behalf of the Trustee on the Global Security.
Any such exchange shall be effected through the Depository in accordance with
the procedures of the Depository therefor.

                 (r)      Notwithstanding the foregoing, no Global Security
shall be registered for transfer or exchange, or authenticated and delivered,
whether pursuant to this Section, Section 2.7, 2.10 or 3.7 or otherwise , in
the name of a person other than the Depository for such Global Security or its
nominee until (i) the Depository notifies the Company that it is unwilling or
unable to continue as Depository for such Global Security or if at any time the
Depository ceases to be a clearing agency registered under the Exchange Act,
and a successor depository is not appointed by the Company within 30 days, (ii)
the Company executes and delivers to the Trustee a Company order





                                       23
<PAGE>   31
that all such Global Securities shall be exchangeable or (iii) there shall have
occurred and be continuing an Event of Default.  Upon the occurrence in respect
of any Global Security representing the Series A Notes of any one or more of
the conditions specified in clause (i), (ii) or (iii) of the preceding
sentence, such Global Security may be registered for transfer or exchange for
Series A Notes registered in the names of, authenticated and delivered to, such
persons as the Trustee or the Depository, as the case may be, shall direct.

                 (s)      Except as provided above, any Security authenticated
and delivered upon registration of transfer of, or in exchange for, or in lieu
of, any Global Security, whether pursuant to this Section 2.7, 2.10 or 3.7 or
otherwise, shall also be a Global Security and bear the legend specified in
footnote 1 to Exhibit A.

SECTION  2.7     Replacement Securities.

         If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security claims that the Security has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of the Trustee are met.  An indemnity bond may be
required by the Trustee, the Company or any Subsidiary Guarantor that is
sufficient in the judgment of the Company, the Subsidiary Guarantors and the
Trustee to protect the Company, the Subsidiary Guarantors, the Trustee or any
Agent from any loss which any of them may suffer if a Security is replaced.
The Company may charge for its expenses (including fees and expenses of the
Trustee) in replacing a Security.

SECTION  2.8     Outstanding Securities.

         Senior Notes outstanding at any time are all Securities authenticated
by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section 2.8 as not outstanding.  Except as set forth in Section 2.9, a
Security does not cease to be outstanding because the Company, the Subsidiary
Guarantors or any of their respective Subsidiaries or Affiliates holds the
Security.

         If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the principal amount of any Security is considered paid under
Section 4.1, it ceases to be outstanding and interest on it ceases to accrue.

SECTION  2.9     Treasury Securities.

         In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, any Subsidiary Guarantor or an Affiliate of the Company shall
be considered as though they are not outstanding,





                                       24
<PAGE>   32
except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities
which the Trustee knows are so owned shall be so disregarded.

SECTION  2.10    Temporary Securities.

         Until definitive Securities are ready for delivery, the Company may
prepare and, upon written order of the Company, the Trustee shall authenticate
temporary Securities.  Temporary Securities shall be substantially in the form
of definitive Securities but may have variations that the Company considers
appropriate for temporary Securities.  Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate and deliver definitive
Securities in exchange for a like principal amount of temporary Securities
surrendered to it.  Until so exchanged, temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

SECTION  2.11    Cancellation.

         The Company or any Subsidiary Guarantor at any time may deliver
Securities to the Trustee for cancellation.  The Registrar and Paying Agent
shall forward to the Trustee any Securities surrendered to them for transfer,
exchange or payment.  The Trustee shall cancel all Securities surrendered for
registration, transfer, exchange, payment or cancellation and shall destroy
canceled Securities unless the Company directs their return to the Company.
Except as provided in Section 2.7, the Company may not issue new Securities to
replace Securities that it has paid or delivered to the Trustee for
cancellation.

         Securities that are redeemed by the Company or that are otherwise
acquired by the Company, will be surrendered to the Trustee for cancellation.

SECTION  2.12    Defaulted Interest.

         If the Company defaults in a payment of interest on the Securities, it
shall pay, or cause the Paying Agent to pay, the defaulted interest in any
lawful manner (plus interest on such defaulted interest to the extent lawful)
(taken together, the "Defaulted Interest") to the persons who are Holders on a
subsequent special record date, in each case at the rate provided in the
Securities and in Section 4.1 hereof.  At least 15 days before the special
record date, the Company shall mail to each Holder a notice stating the special
record date, the payment date and the amount of Defaulted Interest to be paid.
In the event that the Company has elected to cause a Paying Agent to pay the
Defaulted Interest, the Company shall so notify the Paying Agent at least 15
days before the special record date, which notice shall also set forth the
special record date, the payment date and the aggregate amount of Defaulted
Interest to be paid.  At least five days before such payment date, the Company
shall deposit with the Paying Agent money sufficient to pay all of the
Defaulted Interest on the payment date therefor and instruct the Paying Agent
in writing to pay to specified Holders on the payment date.  On the payment
date, the Paying Agent shall make the payments in accordance with





                                       25
<PAGE>   33
the Company's written instructions from funds deposited with the Paying Agent
for the purpose of making such Defaulted Interest payments.

SECTION  2.13    Persons Deemed Owners.

         The Company, the Trustee, any Paying Agent and any authenticating
agent may treat the Person in whose name any Security (including, without
limitation, any Global Security) is registered as the owner of such Security
for the purpose of receiving payments of principal of, premium, if any, or
interest on such Security and for all other purposes.  None of the Company, the
Trustee, any Paying Agent or any authenticating agent shall be affected by any
notice to the contrary.

                                  ARTICLE III

                                   REDEMPTION

SECTION  3.1     Notice to Trustee.

         If the Company elects to redeem Securities pursuant to the optional
redemption provisions of Paragraphs 6, 7 or 8 of the Securities, it shall
furnish to the Trustee and the Registrar, at least 45 days but not more than 60
days before the redemption date (unless the Trustee consents to a shorter
period in writing), an Officers' Certificate setting forth the redemption date,
the principal amount of Securities to be redeemed and the redemption price,
including the detail of the calculation of the Make-Whole Price, if applicable.

SECTION  3.2     Selection of Securities to Be Redeemed.

         If less than all of the Securities are to be redeemed at any time, the
Trustee shall select the Securities to be redeemed pro rata, by lot or, if the
Securities are listed on any securities exchange, by any other method that the
Trustee considers fair and appropriate and that complies with the requirements
of such exchange; provided, however, that no Securities with a principal amount
of $1,000 or less will be redeemed in part.  The Trustee shall make the
selection from outstanding Securities not previously called for redemption not
less than 30 nor more than 45 days prior to the redemption date.  Securities
and portions of them it selects shall be in amounts of $1,000 or whole
multiples 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 selected for redemption.

SECTION  3.3     Notice of Redemption.

                 (a)      At least 30 days but not more than 60 days before a
redemption date, the Company shall mail a notice of redemption by first-class
mail to each Holder of Securities to be redeemed at such Holder's registered
address.





                                       26
<PAGE>   34
                          (i)     The notice shall identify the Securities to
         be redeemed and shall state:

                          (ii)    the redemption date;

                          (iii)   the redemption price;

                          (iv)    the aggregate principal amount of Securities
         being redeemed;

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

                          (vi)    that Securities called for redemption must be
         surrendered to the Paying Agent at the address specified in such
         notice to collect the redemption price;

                          (vii)   that, unless the Company defaults in the
         payment of the redemption price or accrued interest, interest on
         Securities called for redemption ceases to accrue on and after the
         redemption date and the only remaining right of the Holders is to
         receive payment of the redemption prices in respect of the Securities
         upon surrender to the Paying Agent of the Securities;

                          (viii)  if any Security is being redeemed in part,
         the portion of the principal amount of such Security to be redeemed
         and that, after the redemption date, upon surrender of such Security,
         a new Security or Securities in principal amount equal to the
         unredeemed portion will be issued in the name of the Holder thereof
         upon cancellation of the Security or Securities being redeemed;

                          (ix)    the paragraph of the Securities pursuant to
         which the Securities called for redemption are being redeemed; and

                          (x)     the CUSIP number of the Securities.

                 (b)      At the Company's request, the Trustee shall give the
notice of redemption required in Section 3.3(a) in the Company's name and at
the Company's expense; provided, however, that the Company shall deliver to the
Trustee, at least 45 days prior to the redemption date (unless the Trustee
consents to a shorter notice period in writing), an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in Section 3.3(a).

SECTION  3.4     Effect of Notice of Redemption.

         Once notice of redemption is mailed in accordance with Section 3.3,

accompanied by a written statement of the Company's independent public
accountants (which shall be a firm of established national reputation) that in

nothing has come to their attention that would lead them to believe that the
Company has violated any provisions of Sections 4.7, 4.8, 4.9 or 4.10 of this
Indenture (to the extent such provisions relate to accounting matters) or, if
any such violation has occurred, specifying the nature and period of existence
thereof.  Where such financial statements are not accompanied by such a written
statement, the Company shall furnish the Trustee with an Officers' Certificate
stating that any such written statement would be contrary to the then current

rescind such designations; provided, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in the Borough of Manhattan, The City of New York, for such purposes.
The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

provided, that the Company shall not be required to preserve the corporate
existence of any Subsidiary, or any such right or franchise, if the Board of

SECTION  4.6     Waiver of Stay, Extension or Usury Laws.

         The Company and each Subsidiary Guarantor covenants (to the extent
that each may lawfully do so) that it will not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension, or usury law or other law, which would prohibit or forgive the
Company or any Subsidiary Guarantor from paying all or any portion of the
principal of, premium, if any, or interest on the Securities as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this Indenture; and (to the extent
that it may lawfully do so) each of the Company and the Subsidiary Guarantors
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

SECTION  4.7     Payment of Taxes and Other Claims.

         The Company shall pay or discharge or cause to be paid or discharged,

governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary and (b)

be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate

improvements thereof, all as in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company from discontinuing the operation

<PAGE>   40
or maintenance of any such property, or disposing of it, if such discontinuance
or disposal is, in the judgment of the Company, desirable in the conduct of its
business and not disadvantageous in any material respect to the Holders.

                 (b)      The Company shall provide or cause to be provided,
for itself and each of its Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the reasonable,
good faith opinion of the Company, are adequate and appropriate for the conduct
of the business of the Company and such Subsidiaries in a prudent manner, with
reputable insurers or with the government of the United States or an agency or
instrumentality thereof, in such amounts, with such deductibles, and by such
methods as shall be customary, in the reasonable, good faith opinion of the

                 Guarantor in the payment of any installment of interest on the
                 Securities when due and payable and continuance of such
                 default for 30 days;

                 taken together with the principal amount of any other such

                          (5)     default in the performance, or breach of, the

                 principal amount of the outstanding Securities;

                          (6)     the entry by a court of one or more judgments
                 or orders for the payment of money against the Company, any
                 Subsidiary Guarantor or any other Restricted Subsidiary in an
                 aggregate amount in excess of $10.0 million (net of applicable
                 insurance coverage by a third party insurer which is
                 acknowledged in writing by such insurer) that has not been

                                  (A)      is for relief (with respect to the
                 petition commencing such case) against the Company or any

SECTION  6.2     Acceleration.

         If an Event of Default (other than an Event of Default specified in
clauses 8 or 9) under Section 6.1 occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% of the principal
amount of the outstanding Securities may declare the unpaid principal of and
premium, if any, or the Change of Control purchase price if the Event of
Default includes failure to pay the Change of Control purchase price, and
accrued and unpaid interest on, all the Securities then outstanding to be due
and payable, by a notice in writing to the Company (and to the Trustee, if
given by Holders), and upon any such declaration such principal, premium, if
any, and accrued and unpaid interest shall become immediately due and payable,
notwithstanding anything contained in this Indenture or the Securities to the
contrary.  If an Event of Default specified in clauses 8 or 9 above occurs, all
unpaid principal of, and premium, if any, and accrued and unpaid interest on,
the Securities then outstanding will become due and payable, without any
declaration or other act on the part of the Trustee or any Holder.

         The Holders of a majority of the principal amount of the outstanding
Securities, by written notice to the Company, the Subsidiary Guarantors and the
Trustee, may rescind and annul a declaration of acceleration and its
consequences if (1) the Company or any Subsidiary Guarantor has paid or
deposited with such Trustee a sum sufficient to pay (A) all overdue
installments of interest





                                       38
<PAGE>   46
on all the Securities, (B) the principal of, and premium, if any, on any
Securities that have become due otherwise than by such declaration of
acceleration and interest thereon at the rate or rates prescribed therefor in
the Securities, (C) to the extent that payment of such interest is lawful,
interest on the defaulted interest at the rate or rates prescribed therefor in
the Securities, and (D) all money paid or advanced by the Trustee thereunder
and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; (2) all Events of Default, other than the
non-payment of the principal of any Securities that have become due solely by
such declaration of acceleration, have been cured or waived as provided in this
Indenture; and (3) the rescission would not conflict with any judgment or
decree of a court of competent jurisdiction.  No such rescission will affect
any subsequent Event of Default or impair any right consequent thereon.

SECTION  6.3     Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may, but
is not obligated to, pursue, in its own name and as trustee of an express
trust, any available remedy by proceeding at law or in equity to collect the
payment of principal or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.  If an Event
of Default specified under clauses (8) or (9) of Section 6.1 occurs with
respect to the Company at a time when the Company is the Paying Agent, the
Trustee shall automatically assume the duties of Paying Agent.  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  6.4     Waiver of Past Defaults.

         Subject to Sections 6.7 and 9.2, the Holders of at least a majority of
the principal amount of the outstanding Securities by notice to the Trustee may
waive an existing Default or Event of Default and its consequences, except a
Default or Event of Default in payment of principal or interest on the
Securities, including any optional redemption payments or Change of Control or
Net Proceeds Offer payments.

SECTION  6.5     Control by Majority.

         The Holders of a majority in principal amount of the Securities 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, provided that (1) such direction is not in
conflict with any rule of law or with this Indenture and (2) the Trustee may
take any other action deemed proper by such Trustee that is not inconsistent
with such direction.

<PAGE>   47
SECTION  6.6     Limitation on Remedies.

         No Holder of any of the Securities will have any right to institute
any proceeding, judicial or otherwise, or for the appointment of a receiver or
trustee or pursue any remedy under this Indenture, unless:

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

                          (2)     the Holders of not less than 25% of the
                 principal amount of the outstanding Securities have made
                 written request to such Trustee to institute proceedings in
                 respect of such Event of Default in its own name as Trustee
                 under this Indenture,

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

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

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

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

SECTION  6.7     Rights of Holders to Receive Payment.

         Notwithstanding any other provision of this Indenture, the Holder of
any Securities will have the right, which is absolute and unconditional, to
receive payment of the principal of and interest on such Securities on the
stated maturity therefor and to institute suit for the enforcement of any such
payment, and such right may not be impaired without the consent of such Holder.

SECTION  6.8     Collection Suit by Trustee.

         If an Event of Default in payment of principal, premium, if any, or
interest specified in Section 6.1(1), (2) or (3) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company or any Subsidiary Guarantor for the whole amount of
principal, premium, if any, and interest remaining unpaid with respect to the
Securities, and interest on overdue principal and premium, if any, and, to the
extent lawful, interest on overdue interest, and such further amounts as shall
be sufficient to cover the costs and expenses





                                       40
<PAGE>   48
of collection, including the reasonable compensation and expenses of the
Trustee, its agents and counsel.

SECTION  6.9     Trustee May File Proofs of Claim.

                 (a)      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, the Subsidiary Guarantors, their creditors or their
property and may collect and receive any money or securities or other property
payable or deliverable on any such claims and to distribute the same.

                 (b)      Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION  6.10    Priorities.

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

         First:  to the Trustee for amounts due under Section 7.7;

         Second:  to Holders for amounts due and unpaid on the Securities for
principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Securities for principal and
interest, respectively; and

         Third:    To the Company.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10.

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 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.7, or a suit by Holders of more than 10% in principal
amount of the then outstanding Securities.

                                  ARTICLE VII

                                    TRUSTEE

SECTION  7.1     Duties of Trustee.

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

Except during the continuance of an Event of Default:

                          (i)     The Trustee need perform only those duties
         that are specifically set forth (or incorporated by reference) in this
         Indenture and no others.

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

                          (iii)   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:

                          (iv)    This paragraph (c) does not limit the effect
         of paragraph (b) of this Section.

                          (v)     The Trustee shall not be liable for any error
         of judgment made in good faith by an officer of the Trustee, unless it
         is proved that the Trustee was negligent in ascertaining the pertinent
         facts.

                          (vi)    The Trustee shall not be liable with respect
         to action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.5, and the Trustee
         shall be entitled from time to time to request such a direction.

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

                 (c)      The Trustee shall be under no obligation and may
refuse to perform any duty or exercise any right or power unless it receives
indemnity satisfactory to it against any loss, liability or expense.  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





                                       42
<PAGE>   50
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.

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

SECTION  7.2     Rights of Trustee.

         Subject to Section 7.1:

                 (a)      The Trustee may rely on and shall be protected in
acting or refraining from acting upon any document believed by it to be genuine
and to have been signed or presented by the proper person.  The Trustee shall
not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee
shall determine to make such further inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company, personally
or by agent or attorney, to the extent reasonably required by such inquiry or
investigation.

                 (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 such certificate or opinion.

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

                 (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.

SECTION  7.3     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
Subsidiaries or Affiliates with the same rights it would have if it were not
Trustee.  Any Agent may do the same with like rights.  However, the Trustee
must comply with Sections 7.10 and 7.11.

SECTION  7.4     Trustee's Disclaimer.

         The Trustee 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 or





                                       43
<PAGE>   51
any prospectus, offering or solicitation documents, and it shall not be
responsible for any statement in the Securities other than its certificate of
authentication.

SECTION  7.5     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 pursuant to Section 11.2 a
notice of the Default within 90 days after it occurs.  Except in the case of a
Default in any payment on any Security, the Trustee may withhold the notice if
and so long as the board of directors, executive committee or a trust committee
of officers in good faith determines that withholding the notice is in the
interests of Holders.

SECTION  7.6     Reports by Trustee to Holders.

         Within 60 days after each May 15, beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to each Holder a brief
report dated as of such May 15 that complies with TIA Section 313(a), but only
if such report is required in any year under TIA Section 313(a).  The Trustee
also shall comply with TIA Sections 313(b) and 313(c).

         A copy of each report at the time of its mailing to Holders shall be
filed with the SEC and each stock exchange on which the Securities are listed.
The Company shall notify the Trustee in writing when the Securities become
listed on any national securities exchange or of any delisting thereof.

SECTION  7.7     Compensation and Indemnity.

         The Company and the Subsidiary Guarantors jointly and severally agree
to pay the Trustee from time to time reasonable compensation for its services
(which compensation shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust).  The Company and the
Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon
request for all reasonable out-of-pocket expenses, disbursements and advances
incurred by it.  Such expenses shall include when applicable the reasonable
compensation and expenses of the Trustee's agents and counsel.

         The Trustee shall not be under any obligation to institute any suit,
or take any remedial action under this Indenture, or to enter any appearance or
in any way defend any suit in which it may be a defendant, or to take any steps
in the execution of the trusts created hereby or thereby or in the enforcement
of any rights and powers under this Indenture, until it shall be indemnified to
its satisfaction against any and all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provisions of
this Indenture, including compensation for services, costs, expenses, outlays,
counsel fees and other disbursements, and against all liability not due to its
negligence or willful misconduct.  The Company and the Subsidiary Guarantors
jointly and severally agree to indemnify the Trustee against any loss,
liability or expenses incurred by it arising out of or in connection with the
acceptance and administration of the trust and its duties





                                       44
<PAGE>   52
hereunder as Trustee, Registrar and/or Paying Agent, including the costs and
expenses of enforcing this Indenture against the Company (including with
respect to this Section 7.7) and of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers
or duties hereunder.  The Trustee shall notify the Company and the Subsidiary
Guarantors of any claim for which it may seek indemnity; however, unless the
position of the Company is prejudiced by such failure, the failure of the
Trustee to promptly notify the Company shall not limit its right to
indemnification.  The Company shall defend each such claim and the Trustee
shall cooperate in the defense.  The Trustee may retain separate counsel and
the Company shall reimburse the Trustee for the reasonable fees and expenses of
such counsel.  The Company need not pay for any settlement made without its
consent.  Neither the Company nor the Subsidiary Guarantors shall be obligated
to reimburse any expense or indemnify against any loss or liability incurred by
the Trustee through the Trustee's negligence or willful misconduct.  To secure
the payment obligations of the Company and the Subsidiary Guarantors in this
Section, the Trustee shall have a claim prior to that of the Holders of the
Securities on all money or property held or collected by the Trustee, except
that held in trust to pay principal of and interest on particular Securities.
The Trustee's right to receive payment of any amounts due under this Section
7.7 shall not be subordinate to any other liability or Indebtedness of the
Company.  When the Trustee incurs expenses or renders services after the
occurrence of any Event of Default specified in Sections 6.1(8) or (9), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law.

SECTION  7.8     Replacement of Trustee.

                          (i)     The Trustee may resign by so notifying the
         Company and the Subsidiary Guarantors.  The Holders of a majority in
         principal amount of the Securities may remove the Trustee by so
         notifying the Trustee, in writing.  The Company may remove the Trustee
         if:

                          (ii)    the Trustee fails to comply with Section 7.1;

                          (iii)   the Trustee is adjudged a bankrupt or an
         insolvent;

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

                          (v)     the Trustee becomes incapable of acting as
         Trustee hereunder.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.  Within one year after the





                                       45
<PAGE>   53
successor Trustee takes office, the Holders of a majority in principal amount
of the Securities may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company and the Subsidiary
Guarantors.  Immediately after that, the retiring Trustee shall transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.7, 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.  A successor Trustee
shall mail notice of its succession to each Holder.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or
the Holders of a majority in principal amount of the Securities may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.  Any successor Trustee shall comply
with TIA Section 310(a)(5).

SECTION  7.9     Successor Trustee by Merger, etc.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust assets to, another corporation, the
successor corporation without any further act shall be the successor Trustee;
provided such corporation or association shall be otherwise eligible and
qualified under this Article.

SECTION  7.10    Eligibility; Disqualification.

         This Indenture shall always have a Trustee which satisfies the
requirements of TIA Section 310(a)(1).  The Trustee shall always 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 also comply
with TIA Section 310(b).

SECTION  7.11    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 VIII

                             DISCHARGE OF INDENTURE

SECTION  8.1     Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by
a resolution set forth in an Officers' Certificate, at any time, with respect
to the Securities, elect to exercise its rights pursuant to either Section 8.2
or 8.3 with respect to all outstanding Securities upon compliance with the
conditions set forth below in this Article Eight.

SECTION  8.2     Legal Defeasance and Discharge.

         Upon the Company's exercise under Section 8.1 of the option applicable
to this Section 8.2, the Company and the Subsidiary Guarantors shall be deemed
to have been discharged from their obligations with respect to all outstanding
Securities on the date all conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Securities, which shall thereafter
be deemed to be "outstanding" only for the purposes of Section 8.5 and the
other Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Securities and this Indenture
(and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which
shall survive until otherwise terminated or discharged hereunder: (a) the
rights of Holders of outstanding Securities to receive solely from the trust
fund described in Section 8.4, and as more fully set forth in such Section,
payments in respect of the principal of, premium, if any, and interest on such
Securities when such payments are due, (b) the Company's obligations with
respect to such Securities under Sections 2.3, 2.4, 2.6, 2.7, 2.10 and 4.4, (c)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company's obligations in connection therewith (including, but not limited
to, Section 7.7) and (d) this Article Eight.  Subject to compliance with this
Article Eight, the Company may exercise its option under this Section 8.2
notwithstanding the prior exercise of its option under Section 8.3 with respect
to the Securities.

SECTION  8.3     Covenant Defeasance.

         Upon the Company's exercise under Section  8.1 of the option
applicable to this Section 8.3, the Company shall be released from its
obligations under the covenants contained in Sections 4.7, 4.8, 4.9 and 4.10
and Article Five with respect to the outstanding Securities on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Securities shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
outstanding for accounting purposes).  For this





                                       47
<PAGE>   55
purpose, such Covenant Defeasance means that, with respect to the outstanding
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.1(5),
but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.  In addition, upon the Company's
exercise under Section 8.1 of the option applicable to this Section 8.3,
Sections 6.1(4) through 6.1(9) shall not constitute Events of Default.

SECTION  8.4     Conditions to Legal or Covenant Defeasance.

         The following shall be the conditions to application of either Section
8.2 or Section 8.3 to the outstanding Securities:

                 (a)      The Company shall irrevocably have deposited or cause
to be deposited with the Trustee (or another trustee satisfying the
requirements of Section 7.10 who shall agree to comply with the provisions of
this Article Eight applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Securities, (a) cash in
U.S. Legal Tender in an amount, or (b) non-callable U.S. Government Securities
which through the scheduled payment of principal and interest in respect
thereof in accordance with their terms will provide, not later than one day
before the due date of any payment, cash in U.S. Legal Tender in an amount, or
(c) a combination thereof, in such amounts, as will be sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge the principal of, premium, if any, and interest
on the outstanding Securities on the Maturity Date or on the applicable
redemption date, as the case may be, of such principal or installment of
principal, premium, if any, or interest and in accordance with the terms of
this Indenture and of such Securities; provided that the Trustee shall have
been irrevocably instructed to apply such money or the proceeds of such non-
callable Government Securities to said payments with respect to the Securities.

                 (b)      In the case of an election under Section 8.2, the
Company shall have delivered to the Trustee an Opinion of Counsel confirming
that (i) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (ii) since the date hereof, there has been
a change in the applicable federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of the
outstanding Securities will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;





                                       48
<PAGE>   56
                 (c)      In the case of an election under Section 8.3, the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of the outstanding Securities 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;

                 (d)      No Default or Event of Default with respect to the
Securities shall have occurred and be continuing on the date of such deposit
or, insofar as Subsection 6.1(8) or 6.1(9) is concerned, at any time in the
period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period);

                 (e)      Such Legal Defeasance or Covenant Defeasance shall
not result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is
a party or by which the Company is bound;

                 (f)      In the case of any election under Section 8.2 or 8.3,
the Company shall have delivered to the Trustee an Officers' Certificate
stating that the deposit made by the Company pursuant to its election under
Section 8.2 or 8.3 was not made by the Company with the intent of preferring
the Holders over other creditors of the Company or with the intent of
defeating, hindering, delaying or defrauding creditors of the Company or
others; and

                 (g)      The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for relating to either the Legal Defeasance under
Section 8.2 or the Covenant Defeasance under Section 8.3 (as the case may be)
have been complied with as contemplated by this Section 8.4.

SECTION  8.5     Deposited Money and U.S. Government Securities to be Held in
                 Trust; Other Miscellaneous Provisions.

         Subject to Section 8.6, all money and non-callable U.S. Government
Securities (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.5, the
"Trustee") pursuant to Section 8.4 in respect of the outstanding Securities
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company or a Subsidiary
Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the
Holders of such Securities of all sums due and to become due thereon in respect
of principal, premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable U.S.
Government Securities deposited pursuant to Section 8.4 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.





                                       49
<PAGE>   57
Anything in this Article Eight to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the Company's
request any money or non-callable U.S. Government Securities held by it as
provided in Section 8.4 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.4(a)), are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION  8.6     Repayment to Company.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Security which is not subject to the last paragraph of
Section 8.5 and has remained unclaimed for one year after such principal, and
premium, if any, or interest has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Securities shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

SECTION  8.7     Reinstatement.

         If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or non-callable U.S. Government Securities in accordance with Section
8.2 or 8.3, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining, or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.2 or 8.3 until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 8.2 or 8.3, as
the case may be; provided, however, that, if the Company makes any payment of
principal of, premium, if any, or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held
by the Trustee or Paying Agent.

                                   ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS


SECTION  9.1     Without Consent of Holders.

         The Company, the Subsidiary Guarantors and the Trustee may amend or
supplement this Indenture or the Securities without notice to or consent of any
Holder:

                          (1)     to cure any ambiguity, defect or
                                  inconsistency;

                          (2)     to comply with Section 5.1;

                          (3)     to reflect the addition or release of any
                 Subsidiary Guarantor, as provided for by this Indenture;

                          (4)     to comply with any requirements of the SEC in
                 order to effect or maintain the qualification of this
                 Indenture under the TIA; or

                          (5)     to make any change that would provide any
                 additional benefit or rights to the Holders or that does not
                 adversely affect the rights of any Holder in any material
                 respect.

         Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board Resolution of the Company and of each Subsidiary
Guarantor authorizing the execution of any such supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 9.6, the
Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of any supplemental indenture authorized or permitted by the terms of
this Indenture and make any further appropriate agreements and stipulations
that may be therein contained.  After an amendment or waiver under this Section
becomes effective, the Company shall mail to the Holders of each Security
affected thereby a notice briefly describing the amendment or waiver.  Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

SECTION  9.2     With Consent of Holders.

         Except as provided below in this Section 9.2, the Company, the
Subsidiary Guarantors and the Trustee may amend this Indenture or the
Securities with the written consent (including consents obtained in connection
with a tender offer or exchange offer for Securities or a solicitation of
consents in respect of Securities, provided that in each case such offer or
solicitation is made to all Holders of then outstanding Securities on equal
terms) of the Holders of at least a majority of the principal amount of the
outstanding Securities.





                                       51
<PAGE>   59
Upon the request of the Company and the Subsidiary Guarantors, accompanied by a
Board Resolution of the Company and each Subsidiary Guarantor authorizing the
execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of the Holders as aforesaid, and upon
receipt by the Trustee of the Opinion of Counsel described in Section 9.6, the
Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of such supplemental indenture.

         It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment or waiver, but
it shall be sufficient if such consent approves the substance thereof.  The
Holders of a majority of the principal amount of the outstanding Securities may
waive compliance in a particular instance by the Company or the Subsidiary
Guarantors with any provision of this Indenture or the Securities (including
waivers obtained in connection with a tender offer or exchange offer for
Securities or a solicitation of consents in respect of Securities, provided
that in each case such offer or solicitation is made to all Holders of the then
outstanding Securities on equal terms).  However, without the consent of each
Holder affected, an amendment or waiver under this Section may not:

                          (1)     reduce the percentage of principal amount of
                 Securities whose Holders must consent to an amendment,
                 supplement or waiver of any provision of this Indenture or the
                 Securities;

                          (2)     reduce the rate or change the time for
                 payment of interest, including default interest, on the
                 Securities;

                          (3)     reduce the principal amount of any Security
                 or change the Maturity Date of the Securities;

                          (4)     reduce the redemption price, including
                 premium, if any, payable upon the redemption of any Security
                 or change the time at which any Security may be redeemed;

                          (5)     waive a Default or Event of Default in the
                 payment of the principal of, premium, if any, or interest on
                 the Securities;

                          (6)     make any Security payable in money other than
                 that stated in the Security;

                          (7)     impair the right to institute suit for the
                 enforcement of principal of, premium, if any, or principal on
                 any Security pursuant to Sections 6.7 or 6.8, except as
                 limited by Section 6.6; or





                                       52
<PAGE>   60
                          (8)     make any change in Section 6.4 or Section 6.7
                 or in this sentence of this Section 9.2.

         The right of any Holder to participate in any consent required or
sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of
record of any Securities with respect to which such consent is required or
sought as of a date identified by the Trustee in a notice furnished to Holders
in accordance with the terms of this Indenture.

SECTION  9.3     Compliance with Trust Indenture Act.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with the TIA as then in effect.

SECTION  9.4     Revocation and Effect of Consents.

         A consent to an amendment, supplement or waiver by a Holder of a
Security shall bind the Holder and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security, even if notation of the consent is not made on any Security.
However, until an amendment, supplement or waiver becomes effective, any such
Holder or subsequent Holder may revoke the consent as to its Security or
portion of a Security.  For such revocation to be effective, the Trustee must
receive the notice of revocation before the date the amendment, supplement or
waiver becomes effective.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver.  If the Company elects to fix a record date for such purpose, the
record date shall be fixed at (i) the later of 30 days prior to the first
solicitation of such consent or the date of the most recent list of Holders
furnished to the Trustee prior to such solicitation pursuant to Section 2.5, or
(ii) such other date as the Company shall designate.  If a record date is
fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to
such amendment or waiver or to revoke any consent previously given, whether or
not such Persons continue to be Holders after such record date.  No consent
shall be valid or effective for more than 90 days after such record date unless
consent from the Holders of the principal amount of Securities required
hereunder for such amendment or waiver to be effective also shall have been
given and not revoked within such 90-day period.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder unless it makes a change described in any of clauses (i)
through (ix) of Section 9.2.  In that case the amendment, supplement or waiver
shall bind each Holder of a Security who has consented to it and





                                       53
<PAGE>   61
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security.

SECTION  9.5     Notation on or Exchange of Securities.

         If an amendment, supplement or waiver 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 about
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.

SECTION  9.6     Trustee Protected.

         The Trustee shall sign any amendment or supplement or waiver
authorized pursuant to this Article if the amendment or supplement or waiver
does not adversely affect the rights of the Trustee.  If it does adversely
affect the rights of the Trustee, the Trustee may but need not sign it.  In
signing such amendment or supplement or waiver the Trustee shall be entitled to
receive, and (subject to Article Seven) shall be fully protected in relying
upon, an Opinion of Counsel stating that such amendment or supplement or waiver
is authorized or permitted by and complies with this Indenture.  The Company
may not sign an amendment or supplement until the Boards of Directors of the
Company and the Subsidiary Guarantors approve it.

                                   ARTICLE X

                                   GUARANTEES

SECTION  10.1    Unconditional Guarantee.

         Each Subsidiary Guarantor hereby, jointly and severally,
unconditionally guarantees (such guarantee to be referred to herein as the
"Guarantee") to each Holder and to the Trustee the due and punctual payment of
the principal of, premium, if any, and interest on the Securities and all other
amounts due and payable under this Indenture and the Securities by the Company
whether at maturity, by acceleration, redemption, repurchase or otherwise,
including, without limitation, interest on the overdue principal of, premium,
if any, and interest on the Securities, to the extent lawful, all in accordance
with the terms hereof and thereof; subject, however, to the limitations set
forth in Section 10.5.

         Failing payment when due of any amount so guaranteed for whatever
reason, the Subsidiary Guarantors will be jointly and severally obligated to
pay the same immediately.  Each Subsidiary Guarantor hereby agrees that its
obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Securities or this Indenture, the absence
of any action to enforce the same, any waiver or consent by any Holder of the
Securities with respect to any provisions hereof or thereof, the recovery of
any judgment against the Company, any action to

enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company,
any right to require a proceeding first against the Company, protest, notice
and all demands whatsoever and covenants that this Guarantee will not be
discharged except by complete performance of the obligations contained in the
Securities, this Indenture and in this Guarantee.  If any Holder or the Trustee
is required by any court or otherwise to return to the Company, any Subsidiary
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or any Subsidiary Guarantor, any amount paid
by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.  Each Subsidiary Guarantor agrees it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby.  Each Subsidiary Guarantor further agrees that, as between
each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any acceleration of such obligations as provided in Article Six, such
obligations (whether or not due and payable) shall forthwith become due and
payable by each Subsidiary Guarantor for the purpose of this Guarantee.

SECTION  10.2    Subsidiary Guarantors May Consolidate, etc. on Certain Terms.

                 (a)      Subject to paragraph (b) of this Section 10.2, no
Subsidiary Guarantor may consolidate or merge with or into (whether or not such
Subsidiary Guarantor is the surviving entity or Person) another corporation,
entity or Person unless (i) the entity or Person formed by or surviving any
such consolidation or merger (if other than such Subsidiary Guarantor) assumes
all the obligations of such Subsidiary Guarantor pursuant to a supplemental
indenture, in a form reasonably satisfactory to the Trustee, under the
Securities and this Indenture and (ii) immediately after such transaction, no
Default or Event of Default exists.  In connection with any consolidation or
merger contemplated by this Section 10.2, the Company shall deliver to the
Trustee prior to the consummation of the proposed transaction an Officers'
Certificate to the foregoing effect and an Opinion of Counsel stating that the
proposed transaction and such supplemental indenture comply with this
Indenture.  This Section 10.2(a) will not prohibit a merger between Subsidiary
Guarantors or a merger between the Company and a Subsidiary Guarantor.

                 (b)      In the event of a sale or other disposition of all or
substantially all of the assets of any Subsidiary Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the
Capital Stock of such Subsidiary Guarantor, then such Subsidiary Guarantor (in
the event of a sale or other disposition, by way of such a merger,
consolidation or otherwise, of all of the Capital Stock of such Subsidiary
Guarantor) or the corporation acquiring the property (in the event of a sale or
other disposition of all or substantially all of the assets of such Subsidiary
Guarantor) will be released and relieved of any obligations under its
Guarantees.

SECTION  10.3    Addition of Subsidiary Guarantors.

                 (a)      If any Subsidiary of the Company guarantees any
Funded Indebtedness of the Company at any time subsequent to the Issue Date,
then the Company shall (i) cause the Securities to be equally and ratably
guaranteed by such Subsidiary, but only to the extent that the Securities are
not already guaranteed by such Subsidiary on reasonably comparable terms and
(ii) cause such Subsidiary to execute and deliver a supplemental indenture, in
a form reasonably satisfactory to the Trustee, evidencing its provision of a
guarantee pursuant to the terms hereof.

                 (b)      The Company agrees to cause each Subsidiary other
than a Foreign Subsidiary that shall become a Restricted Subsidiary after the
Issue Date to execute and deliver a supplemental indenture pursuant to which
such Restricted Subsidiary shall guarantee the payment of the Securities
pursuant to the terms hereof.

                 (c)      Any Person that was not a Subsidiary Guarantor on the
Issue Date may become a Guarantor by executing and delivering to the Trustee
(i) a supplemental indenture in form and substance satisfactory to the Trustee,
which subjects such Person to the provisions (including the representations and
warranties) of this Indenture as a Subsidiary Guarantor and (ii) an Opinion of
Counsel and Officers' Certificate to the effect that such supplemental
indenture has been duly authorized and executed by such Person and constitutes
the legal, valid, binding and enforceable obligation of such Person (subject to
such customary exceptions concerning creditors' rights and equitable principles
as may be acceptable to the Trustee in its discretion and provided that no
opinion need be rendered concerning the enforceability of the Guarantee).

SECTION  10.4    Release of a Subsidiary Guarantor.

                 (a)      If, at any time while the Securities remain
outstanding, none of the Company's then outstanding Pari Passu Indebtedness
(other than the Securities) is guaranteed by a Restricted Subsidiary, such
Restricted Subsidiary shall be released and relieved of its obligations under
its Guarantee (which shall be terminated and cease to have any force and
effect).  For purposes of this Section 10.4(a) only, other Pari Passu
Indebtedness shall not be deemed to be outstanding if, and as long as, all
conditions to defeasance thereof have been satisfied, pursuant to defeasance
provisions substantially similar to those set forth in Article Eight hereof.

                 (b)      Upon the sale or disposition of a Subsidiary
Guarantor (or substantially all of its assets), which is otherwise in
compliance with the terms of this Indenture, including but not limited to the
provisions of Section 10.2, or if a Subsidiary ceases to be a Restricted
Subsidiary, such Subsidiary shall be released and relieved of its obligations
under its Guarantee (which shall terminate and cease to have any force and
effect).  The Trustee shall deliver an appropriate instrument evidencing such
release upon receipt of a request by the Company accompanied by an Officers'
Certificate and an Opinion of Counsel certifying that such sale or other
disposition or cessation was made by the Company in accordance with the
provisions of this Indenture.





                                       56
<PAGE>   64
                 (c)      Any Subsidiary Guarantor not so released pursuant to
this Article Ten remains liable for the full amount of principal of and
interest on the Securities as provided in this Article Ten.

SECTION  10.5    Limitation of Subsidiary Guarantor's Liability.

         Each Subsidiary Guarantor, and by its acceptance hereof each Holder,
hereby confirms that it is the intention of all such parties that the guarantee
by such Subsidiary Guarantor pursuant to its Guarantee not constitute a
fraudulent transfer or conveyance for purposes of any federal or state law.  To
effectuate the foregoing intention, the Holders and each Subsidiary Guarantor
hereby irrevocably agree that the obligations of each Subsidiary Guarantor
under the Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Subsidiary
Guarantor and after giving effect to any collections from or payments made by
or on behalf of any other Subsidiary Guarantor in respect of the obligations of
such other Subsidiary Guarantor under its Guarantee or pursuant to Section
10.6, result in the obligations of such Subsidiary Guarantor under the
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal or state law.  This Section 10.5 is for the benefit of the creditors of
each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer
and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor
pursuant to a bank credit facility shall be deemed to have been incurred prior
to the incurrence by such Subsidiary Guarantor of its liability under the
Guarantee.

SECTION  10.6    Contribution.

         In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
"Funding Guarantor") under the Guarantee, such Funding Guarantor shall be
entitled to a contribution from each other Subsidiary Guarantor in a pro rata
amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including
the Funding Guarantor) for all payments, damages and expenses incurred by the
Funding Guarantor in discharging the Company's obligations with respect to the
Securities or any other Subsidiary Guarantor's obligations with respect to the
Guarantee.

SECTION  10.7    Execution and Delivery of Guarantee.

         To further evidence the Guarantees set forth in Section 10.1, each
Subsidiary Guarantor hereby agrees that a notation relating to such Guarantee,
in substantially the form of Exhibit A-1, shall be endorsed on each Security
authenticated and delivered by the Trustee and executed by either manual or
facsimile signature of one Officer of each Subsidiary Guarantor.

         Each of the Subsidiary Guarantors hereby agrees that its Guarantee set
forth in Section 10.1 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation relating to such Guarantee.





                                       57
<PAGE>   65
         If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Security no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, such Subsidiary
Guarantor's Guarantee of such Security shall be valid nevertheless.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Subsidiary Guarantor.

SECTION  10.8    Severability.

         In case any provision of this Guarantee shall be invalid, illegal or
unenforceable, that portion of such provision that is not invalid, illegal or
unenforceable shall remain in effect, and the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

                         CHESAPEAKE ENERGY CORPORATION

                    8 1/2% SERIES [A/B] SENIOR NOTE DUE 2012

       1.       Interest.  Chesapeake Energy Corporation, an Oklahoma
corporation (the "Company"), promises to pay interest on the principal amount
of this Security at 8 1/2% per annum from the Issue Date until maturity.  The
Company will pay interest semiannually on March 15 and September 15 of each
year (each an "Interest Payment Date"), or if any such day is not a Business
Day, on the next succeeding Business Day.  Interest on the Securities will
accrue from the most recent Interest Payment Date on which interest has been
paid or, if no interest has been paid, from the Issue Date; provided, that if
there is no existing Default in the payment of interest, and if this Security
is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be September 15, 1997.  The Company shall pay interest on
overdue principal and premium, if any, from time to time on demand at a rate
equal to the interest rate on the Securities then in effect; it shall pay
interest on overdue installments of interest (without regard to any applicable
grace periods) from time to time on demand at the same rate to the extent
lawful.  Interest will be computed on the basis of a 360-day year of twelve
30-day months.  All references herein to interest shall include additional
interest, if any, payable as Liquidated Damages pursuant to the Registration
Rights Agreement.

       2.       Method of Payment.  The Company will pay interest on the 
Securities to the persons who are registered holders of Securities at the
close of business on the record date immediately preceding the Interest Payment
Date, even if such Securities are canceled after the record date and on or
before the Interest Payment Date. Holders must surrender Securities to the
Paying Agent to collect principal payments.  The Company will pay principal of,
premium, if any, and interest on the Securities in money of the United States
of America that at the time of payment is legal tender for payment of public
and private debts.  However, the Company may pay principal and interest by wire
transfer of Federal Funds, or interest by its check payable in such U.S. Legal
Tender.  The Company may deliver any such interest payment to the Paying Agent
or to a Holder at the Holder's registered address.  Notwithstanding the
foregoing, the Company shall pay or cause to be paid all amounts payable with
respect to Restricted Securities or non-DTC eligible Securities by wire
transfer of Federal funds to the account of the Holders of such Securities.  If
this Security is a Global Security, all payments in respect of this Security
will be made to the Depository or its nominee in immediately available funds in
accordance with customary procedures established from time to time by the
Depository.

       3.       Paying Agent and Registrar.  Initially, the Trustee will act 
as Paying Agent and Registrar.  The Company may change any Paying Agent,
Registrar or co-registrar without notice.  The Company or any of its
Subsidiaries may act as Paying Agent or Registrar.

Indenture, dated as of March 15, 1997 (the "Indenture"), among the Company, the
Subsidiary Guarantors and the Trustee.  Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein.  The terms of the
Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb) as in effect on the date of the Indenture. Notwithstanding
anything to the contrary herein, the Securities are subject to all such terms,
and Holders are referred to the Indenture and such Act for a complete statement
of such terms.  The Securities are limited to $150,000,000 aggregate principal
amount.

       5.       Ranking and Guarantees.  The Securities are general senior 
unsecured obligations of the Company.  The Company's obligation to pay

Subsidiary Guarantors pursuant to Article Ten of the Indenture.  Certain
limitations to the obligations of the Subsidiary Guarantors are set forth in
further detail in the Indenture.

rata, by lot or, if the Securities are listed on any securities exchange, by
any other method that the Trustee considers fair and appropriate and that
complies with the requirements of such exchange; the Securities to be redeemed
in multiples of $1,000; provided, however, that no Securities with a principal
amount of $1,000 or less will be redeemed in part.  Securities in denominations
larger than $1,000 may be redeemed in part.  On and after the redemption date,
interest ceases to accrue on Securities or portions of them called for
redemption (unless the Company shall default in the payment of the redemption
price or accrued interest).

       9.       Restrictive Covenants.  The Indenture imposes certain
limitations on, among other things, the ability of the Company to merge or
consolidate with any other Person or sell, lease or otherwise transfer all or
substantially all of its properties or assets, the ability of the Company or
the Restricted Subsidiaries to incur encumbrances against certain property or
enter into certain sale and leaseback transactions, all subject to certain
limitations described in the Indenture.

       10.      Denominations, Transfer, Exchange.  The Securities shall be 
issued in global form or in accordance with Section 2.6(f) of the Indenture, in
definite registered form, without coupons in denominations of $1,000 and whole
multiples of $1,000.  A Holder may transfer or exchange Securities in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture.  The Registrar need not
transfer or exchange any Securities selected for redemption.  Also, it need not
transfer or exchange any Securities for a period of 15 days before a selection
of Securities to be redeemed.

       11.      Persons Deemed Owners.  The registered Holder of a Security 
may be treated as the owner of it for all purposes and neither the Company, any
Subsidiary Guarantor, the Trustee nor any Agent shall be affected by notice to
the contrary.

       12.      Unclaimed Money.  If money for the payment of principal or 
interest remains unclaimed for one year, the Trustee or Paying Agent will pay
the money back to the Company at its request.  After that, all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

       13.      Amendment, Supplement, Waiver.  Subject to certain exceptions, 
the Indenture or the Securities may be amended or supplemented with the consent
of the Holders of at least a majority of the outstanding principal amount of the
Securities, and any past default or noncompliance with any provision may be
waived with the consent of the Holders of a majority in principal amount of the
Securities.  Without the consent of any Holder, the Company may amend or
supplement the Indenture or the Securities to, among other things, cure any
ambiguity, defect or inconsistency or to make any change that does not adversely
affect the rights of any Holder.

       14.      Successor Corporation.  When a successor corporation
assumes all the obligations of its predecessor under the Securities and the
Indenture, the predecessor corporation will be released from those obligations.





                                      A-6
<PAGE>   79
       15.      Defaults and Remedies.  An event of default generally is: 
default by the Company or any Subsidiary Guarantor for 30 days in payment of
interest on the Securities; default by the Company or any Subsidiary Guarantor
in payment of principal of, or premium, if any, on the Securities; default by
the Company or any Subsidiary Guarantor in the deposit of any optional
redemption payment when due and payable; defaults resulting in acceleration
prior to maturity of certain other Indebtedness or resulting from payment
defaults under certain other Indebtedness; failure by the Company or any
Subsidiary Guarantor for 45 days after notice to comply with any of its other
agreements in the Indenture; certain final judgments against the Company or
Subsidiaries; a failure of any Guarantee of a Subsidiary Guarantor to be in full
force and effect or denial by any Subsidiary Guarantor of its obligations with
respect thereto; and certain events of bankruptcy or insolvency.  Subject to
certain limitations in the Indenture, if an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Securities may declare all the Securities to be due and
payable immediately, except that in the case of an Event of Default arising from
certain events of bankruptcy, insolvency or reorganization relating to the
Company, all outstanding Securities shall become due and payable immediately
without further action or notice.  Holders may not enforce the Indenture or the
Securities except as provided in the Indenture.  The Trustee may require
indemnity satisfactory to it before it enforces the Indenture or the 
Securities.  Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or
power.  The Company must furnish an annual compliance certificate to the
Trustee.

       16.      Trustee Dealings with Company and Subsidiary Guarantors.  
The Trustee under the Indenture, in its individual or any other capacity, may
become the owner or pledgee of Securities and may otherwise deal with the
Company, the Subsidiary Guarantors or their respective Subsidiaries or
Affiliates with the same rights it would have if it were not Trustee.

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

       18.      Authentication.  This Security shall not be valid until the 
Trustee or an authenticating agent signs the certificate of authentication on
the other side of this Security.

       19.      Abbreviations.  Customary abbreviations may be used in the 
name of a Holder or an assignee, such as: TEN COM (=tenants in common), TEN ENT
(=tenants by the entireties), JT TEN (=joint tenants with right of survivorship
and not as tenants in common), CUST (=Custodian), and U/G/M/A (=Uniform Gifts to
Minors Act).

       20.      CUSIP Numbers.  Pursuant to a recommendation promulgated by 
the Committee on Uniform Security Identification Procedures, the Company will
cause CUSIP numbers to be printed

Attention:

Ladies and Gentlemen:

         In connection with our proposed purchase of $_________ aggregate
principal amount of 8 1/2% Senior Notes due 2012 (the "Notes") of Chesapeake
Energy Corporation (the "Company"), we confirm that:

                          (i)     we are an "institutional accredited investor"
         within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
         Securities Act of 1933, as amended (the "Securities Act") (an
         "Institutional Accredited Investor"), or any entity in which all of
         the equity owners are Institutional Accredited Investors;

                          (ii)    any purchase of Notes by us will be for our
         own account or for the account of one or more other Institutional
         Accredited Investors as to which we exercise sole investment
         discretion;

                          (iii)   in the event that we purchase any Notes, we
         will acquire such Notes having a minimum purchase price of at least
         $100,000 for our own account and for each separate account for which
         we exercise sole investment discretion;

                          (iv)    we have such knowledge and experience in
         financial and business matters that we are capable of evaluating the
         merits and risks of purchasing Notes and we





                                      B-1
<PAGE>   85
         and any accounts for which we are acting are able to bear the economic
         risks of our or their investment;

                          (v)     we are not acquiring the Notes with a view to
         any distribution thereof in a transaction that would violate the
         Securities Act or the securities laws of any State of the United
         States or any other applicable jurisdiction; provided that the
         disposition of our property and the property of any accounts for which
         we are acting as shall remain at all times within our control; and

                          (vi)    we have received a copy of the Offering
         Memorandum and acknowledge that we have had access to such financial
         and other information, and have been afforded the opportunity to ask
         such questions of representatives of the Company and receive answers
         thereto, as we deem necessary in connection with our decision to
         purchase Notes.

         We understand that the Notes are being offered in a transaction not
involving any public offering in the United States within the meaning of the
Securities Act and that the Notes have not been registered under the Securities
Act, and we agree, on our own behalf and on behalf of each account for which we
acquire any Notes, that if we should sell or otherwise transfer any Notes prior
to the date which is three years (or such shorter period set forth in Rule
144(k) under the Securities Act, as such provision may be amended) after the
original issuance of the Notes, we will do so only (a) to the Company or any of
its subsidiaries, (b) inside the United States in accordance with Rule 144A
under the Securities Act to a "qualified institutional buyer" (as defined in
Rule 144A under the Securities Act), (c) inside the United States to an
Institutional accredited Investor that, prior to such transfer, furnishes (or
has furnished on its behalf by a U.S. broker-dealer) to the Trustee, a signed
letter contained certain representations and agreements relating to the
restrictions on transfer of the Notes (the form of which letter can be obtained
from the applicable Trustee), (d) outside the United States in accordance with
Regulation S under the Securities Act, (e) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if available), or
(f) pursuant to an effective registration statement under the Securities Act.

         We understand that the registrar will not be required to accept for
registration of transfer any Notes, except upon presentation of evidence
satisfactory to the Company that the foregoing restrictions on transfer have
been complied with.  We understand that, on any proposed resale of any Notes,
we will be required to furnish to the Trustee and the Company such
certification, legal opinions and other information as the Trustee and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions.  We further understand that the Notes purchased by
us will bear a legend reflecting the substance of this paragraph.  We further
agree to provide to any person acquiring any of the Notes from us a notice
advising such person that resales of the Notes are restricted as stated herein.

         We acknowledge that you, the Company and others will rely upon our
confirmation, acknowledgments and agreements set forth herein, and agree to
notify you promptly in writing if any of our representations or warranties
herein cease to be accurate and complete.

Ladies and Gentlemen:

                 Chesapeake Energy Corporation, an Oklahoma corporation (the
"Company"), and its subsidiaries listed on the signature pages hereto (the
"Subsidiary Guarantors") propose to issue and sell to you (the "Initial
Purchasers"), upon the terms set forth in a purchase agreement of even date
herewith (the "Purchase Agreement"), $150,000,000 principal amount of the
Company's 7 7/8% Senior Notes due 2004 (the "2004 Senior Notes") and
$150,000,000 principal amount of the Company's 8 1/2% Senior Notes due 2012
(the "2012 Senior Notes" and, collectively with the 2004 Senior Notes, the
"Senior Notes").  The 2004 Senior Notes and the 2012 Senior Notes will be
issued pursuant to separate indentures, each to be dated as of March 15, 1997
(respectively, the "2004 Senior Notes Indenture" and the "2012 Senior Notes
Indenture" and, collectively, the "Indentures") by and among the Company, the
Subsidiary Guarantors and United States Trust Company of New York, as trustee
(with respect to each of the Indentures, the "Trustee"), substantially in the
forms previously furnished to you.

                 Capitalized terms used but not specifically defined herein are
defined in the Purchase Agreement and used herein as so defined.  References to
each issue of Senior Notes shall include the related Guarantees (as defined in
the related Indenture) of the Subsidiary Guarantors.  As used herein,
"Registrable Senior Notes" shall mean each Senior Note of each issue, until the
earliest to occur of (a) the date on which such Senior Note is exchanged in the
applicable Registered Exchange Offer for an Exchange Note (each as defined
below) of such issue and entitled to be resold to the
<PAGE>   2
public by the holder thereof without complying with the prospectus delivery
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
(b) the date on which such Senior Note has been effectively registered under
the Securities Act and disposed of pursuant to a Senior Notes Shelf
Registration (as defined below) and (c) the date on which such Senior Note is
distributed to the public pursuant to Rule 144 under the Securities Act or by a
Broker-Dealer (as defined below) pursuant to the "Plan of Distribution"
contemplated by the registration statement relating to the Registered Exchange
Offer (including delivery of the prospectus contained therein).

                 In consideration of the premises, and the mutual covenants,
representations, warranties and agreements herein contained, the parties hereby
agree as follows:

                 1.       Registered Exchange Offers.

                 (a)      Promptly (and in any event not more than 60 days)
following the closing date of the sale of the Senior Notes (the "Closing
Date"), the Company and the Subsidiary Guarantors shall file with the
Commission, with respect to each of the 2004 Senior Notes and the 2012 Senior
Notes, a registration statement on an appropriate form under the Securities Act
with respect to proposed offers (the "Registered Exchange Offers") to the
holders of the Registrable Senior Notes of the applicable issue to issue and
deliver to such holders, in exchange for the Registrable Senior Notes of such
issue, a like principal amount of debt securities of the Company identical in
all material respects to the Registrable Senior Notes of such issue (the
"Exchange Notes"), shall use their best efforts to cause such registration
statement to become effective under the Securities Act no later than 160 days
after the Closing Date and, upon the effectiveness of such registration
statement, shall commence each Registered Exchange Offer and shall cause the
same to remain open for such period of time to be determined by the Company
(but not less than 30 nor more than 60 days after the commencement of the
applicable Registered Exchange Offer), and to be conducted in accordance with
such procedures, as may be required by the applicable provisions of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), it being the
objective of such Registered Exchange Offers to enable each holder of
Registrable Senior Notes of the applicable issue electing to exchange
Registrable Senior Notes of such issue for Exchange Notes of such issue
(assuming that such holder is not an affiliate of the Company within the
meaning of the Securities Act, acquires the Exchange Notes in the ordinary
course of such holder's business and has no arrangements with any person to
participate in the distribution of the Exchange Notes) to trade such Exchange
Notes from and after their receipt without any limitations or restrictions
under the Securities Act, subject as to a Broker-Dealer to the provisions of
Section 1(b) hereof, or the Exchange Act and without material restrictions
under the securities laws of a substantial proportion of the several states of
the United States.

                 (b)      The Company shall indicate in a "Plan of
Distribution" section contained in the final prospectus constituting a part of
the registration statement relating to the Registered Exchange Offers that any
broker or dealer registered under the Exchange Act (each a "Broker-Dealer") who
holds Registrable Senior Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than
Registrable Senior Notes acquired





                                      -2-
<PAGE>   3
directly from the Company), may exchange such Registrable Senior Notes for
Exchange Notes of the applicable issue pursuant to the applicable Registered
Exchange Offer; however, such Broker-Dealer may be deemed an "underwriter"
within the meaning of the Securities Act and, therefore, must deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resales of such Exchange Notes received by it in the applicable Registered
Exchange Offer, which prospectus delivery requirement may be satisfied by the
delivery by such Broker-Dealer of the final prospectus contained in the
registration statement relating to such Registered Exchange Offer.  Such "Plan
of Distribution" section also shall state that the delivery by a Broker-Dealer
of the final prospectus relating to the Registered Exchange Offer in connection
with resales of Exchange Notes shall not be deemed to be an admission by such
Broker-Dealer that it is an "underwriter" within the meaning of the Securities
Act, and shall contain all other information with respect to resales of the
Exchange Notes by Broker-Dealers that the Commission may require in connection
therewith, but such "Plan of Distribution" shall not name any such
Broker-Dealer or disclose the amount of Exchange Notes held by any such Broker-
Dealer except to the extent required by the Commission as a result of a change
in policy after the date of this Agreement.

                 (c)      In connection with such Registered Exchange Offers
and the offer and sale of Exchange Notes by Broker-Dealers as contemplated
above, the Company and the Subsidiary Guarantors shall take such other and
further action, including making appropriate filings under state securities
laws and delivering such number of final prospectuses relating to the
Registered Exchange Offers as any Broker-Dealer proposing to deliver the same
in connection with its resales of Exchange Notes may reasonably request, as may
be necessary to realize the foregoing objectives.  The Company and the
Subsidiary Guarantors shall cause the registration statement relating to the
Registered Exchange Offers to remain continuously effective for a period of one
year, if required, from the date on which such registration statement is first
declared effective, and shall supplement or amend the prospectus contained
therein to the extent necessary to permit such prospectus (as supplemented or
amended) to be delivered by Broker-Dealers in connection with their resales of
Exchange Notes as aforesaid.

                 2.       Senior Notes Shelf Registration.  If, because of any
change in currently prevailing interpretations of the Commission's staff, the
Company is not permitted to effect a Registered Exchange Offer, as contemplated
by Section 1 hereof, the following provisions shall apply with respect to each
issue of Senior Notes:

                 (a)      Promptly (and in any event not more than 60 days)
following the date of closing (the "Closing Date") of the sale of the Senior
Notes, the Company and the Subsidiary Guarantors shall file with the
Commission, and thereafter use their best efforts to have declared effective
not later than 160 days after the Closing Date, a registration statement on an
appropriate form under the Securities Act relating to the offer and sale of the
Registrable Senior Notes by the holders thereof, from time to time in
accordance with the methods of distribution set forth in such registration
statement and Rule 415 under the Securities Act (the "Senior Notes Shelf
Registration").





                                      -3-
<PAGE>   4
                 (b)      The Company and the Subsidiary Guarantors agree to
use their best efforts to keep the registration statement relating to the
Senior Notes Shelf Registration continuously effective in order to permit the
prospectus included therein to be usable by the holders of the Registrable
Senior Notes for a period of three years from the Closing Date or such shorter
period (i) as may be set forth in any amendment to Rule 144(k) of the
Securities Act of 1933, or any amendment thereto, when such amendment becomes
effective, or (ii) that will terminate when all the Registrable Senior Notes
covered by the registration statement have been sold pursuant to such
registration statement; provided, that the Company and the Subsidiary
Guarantors shall be deemed not to have used their best efforts to keep the
registration statement effective during the requisite period if they
voluntarily take any action that would result in holders of the Registrable
Senior Notes covered thereby not being able to offer and sell such Registrable
Senior Notes during that period, unless such action is required by applicable
law, and provided, further, that the foregoing shall not apply if the Company
determines, in its reasonable judgment, upon advice of counsel, as authorized
by a resolution of its Board of Directors, that the continued effectiveness and
usability of such registration statement would (i) require the disclosure of
material information, which the Company has a bona fide business reason for
preserving as confidential, or (ii) interfere with any financing, acquisition,
corporate reorganization or other material transaction involving the Company or
any of its Affiliates (as defined in the rules and regulations adopted under
the Exchange Act); provided, however, that the failure to keep the registration
statement effective and usable for offers and sales of Registrable Senior Notes
for such reasons shall last no longer than 60 days in any 12-month period
(whereafter Senior Notes Liquidated Damages (as defined in Section 6) shall
accrue and be payable), so long as the Company promptly thereafter complies
with the requirements of Section 3(h) hereof, if applicable.  Any such period
during which the Company and the Subsidiary Guarantors fail to keep the
registration statement effective and usable for offers and sales of Registrable
Senior Notes is referred to as a "Suspension Period."  A Suspension Period
shall commence on and include the date that the Company gives notice that the
registration statement is no longer effective or the prospectus included
therein is no longer usable for offers and sales of Registrable Senior Notes
and shall end on the date when each seller of Registrable Senior Notes covered
by such registration statement either receives the copies of the supplemented
or amended prospectus contemplated by Section 3(h) hereof or is advised in
writing by the Company that use of the prospectus may be resumed.

                 (c)      Notwithstanding any other provisions of this
Agreement to the contrary, the Company and the Subsidiary Guarantors will cause
the Senior Notes Shelf Registration and the related prospectus and any
amendment or supplement thereto, as of the effective date of such registration
statement, amendment or supplement, (i) to comply in all material respects with
the applicable requirements of the Securities Act and the rules and regulations
of the Commission and (ii) not to contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading.

                 3.       Registration Procedures.  In connection with, to the
extent applicable, any Registered Exchange Offer pursuant to Section 1 hereof,
or any Senior Notes Shelf Registration





                                      -4-
<PAGE>   5
pursuant to Section 2 hereof, the following provisions shall apply with respect
to each issue of Senior Notes:

                 (a)      If requested by any holder of Registrable Senior
Notes or the managing underwriter, if any, with respect to the Senior Notes
Shelf Registration, the Company shall furnish to each such holder of
Registrable Senior Notes or such managing underwriter, prior to the filing
thereof with the Commission, a copy of the applicable registration statement
and each amendment thereof and each supplement, if any, to the prospectus
included therein.  The Company shall use its best efforts to reflect in each
such document, when so filed with the Commission, such comments as such holder
or managing underwriter reasonably may propose.

                 (b)      The Company shall advise the holders of Registrable
Senior Notes or the Exchange Notes, and the managing underwriter, if any, and,
if requested by any such person, confirm such advice in writing:

                 (i)      when the applicable registration statement and any
         amendment thereto has been filed with the Commission and when the
         registration statement or any post-effective amendment thereto has
         become effective;

                 (ii)     of the issuance by the Commission of any stop order
         suspending the effectiveness of the applicable registration statement
         or the initiation of any proceedings for that purpose;

                 (iii)    of the receipt by the Company of any notification
         with respect to the suspension of the qualification of the Registrable
         Senior Notes or the Exchange Notes for sale in any jurisdiction or the
         initiation or threatening of any proceeding for such purpose; and

                 (iv)     of the happening of any event that requires the
         making of any changes in the registration statement or the prospectus
         in order to make the statements therein not misleading (which advice
         shall be accompanied by an instruction to suspend the use of the
         prospectus until the requisite changes have been made).

                 (c)      The Company will make every reasonable effort to
obtain the withdrawal of any order suspending the effectiveness of the
registration statement at the earliest possible time.

                 (d)      The Company will furnish to each holder of the
Registrable Senior Notes or the Exchange Notes included within the coverage of
the Registered Exchange Offer or the Senior Notes Shelf Registration, as
appropriate, without charge, at least one copy of the registration statement in
the form in which it was declared effective by the Commission and any
post-effective amendment thereto, including financial statements and schedules,
and, if the holder so requests in writing, all exhibits (including those
incorporated by reference).

<PAGE>   6
                 (e)      The Company will deliver to each holder of the
Registrable Senior Notes or the Exchange Notes included within the coverage of
the Registered Exchange Offer or the Senior Notes Shelf Registration, as
appropriate, without charge, as many copies of the prospectus (including each
preliminary prospectus) included in the registration statement and any
amendment or supplement thereto as such persons may reasonably request; the
Company consents to the use of the prospectus or any amendment or supplement
thereto by each of the selling holders of the Registrable Senior Notes or the
Exchange Notes in connection with the offering and sale of the Registrable
Senior Notes or the Exchange Notes covered by the prospectus or any amendment
or supplement thereto.

                 (f)      Prior to any public offering of the Registrable
Senior Notes or the Exchange Notes pursuant to the Registered Exchange Offer or
the Senior Notes Shelf Registration, as the case may be, the Company will
register or qualify, or cooperate with the holders of the Registrable Senior
Notes or the Exchange Notes covered thereby and their respective counsel in
connection with the registration or qualification of, such Registrable Senior
Notes or Exchange Notes for offer and sale under the securities or blue sky
laws of such jurisdictions as any seller reasonably requests in writing and do
any and all other acts or things necessary or advisable to enable the offer and
sale in such jurisdictions, of the Registrable Senior Notes or the Exchange
Notes covered by the Registered Exchange Offer or the Senior Notes Shelf
Registration, as the case may be; provided, that the Company will not be
required to qualify generally to do business in any jurisdiction where it is
not then so qualified or to take any action which would subject it to general
service of process or to taxation in any such jurisdiction where it is not then
so subject.

                 (g)      The Company will cooperate with the holders of the
Registrable Senior Notes and the Exchange Notes to facilitate the timely
preparation and delivery of certificates representing the Registrable Senior
Notes and the Exchange Notes to be sold in the Registered Exchange Offer or the
Senior Notes Shelf Registration, as the case may be, free of any restrictive
legends and in such denominations and registered in such names as the holders
may request prior to sales of the Registrable Senior Notes or the Exchange
Notes, pursuant to the Registered Exchange Offer or the Senior Notes Shelf
Registration, as the case may be.

                 (h)      Upon the occurrence of any event contemplated by
paragraph (b)(v) above, the Company will prepare a post-effective amendment to
the registration statement or a supplement to the related prospectus or file
any other required document so that, as thereafter delivered to purchasers of
the Registrable Senior Notes or the Exchange Notes, the prospectus will not
contain an untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading.

                 (i)      Not later than the effective date of the applicable
registration statement, the Company will provide a CUSIP number for the
Registrable Senior Notes or the Exchange Notes, as the case may be, and provide
the Trustee with printed certificates for the Registrable Senior Notes or the
Exchange Notes, as the case may be, in a form eligible for deposit with The
Depository Trust Company.

                 (j)      The Company will use its best efforts to comply with
all applicable rules and regulations of the Commission and will make generally
available to its security holders an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act, no later than 60 days after
the end of 12-month period (or 90 days, if such period is a fiscal year)
beginning with the first month of the Company's first fiscal quarter commencing
after the effective date of each of the Registered  Exchange Offer and the
Senior Notes Shelf Registration, which statements shall cover such 12-month
period.

                 (k)      The Company will cause the Indenture to be qualified
under the Trust Indenture Act of 1939 upon effectiveness of the registration
statement contemplated by Section 1(a) or Section  2(a).

                 (l)      The Company may require each holder of Registrable
Senior Notes to be sold pursuant to the Senior Notes Shelf Registration, to
furnish to the Company such information regarding the holder and the
distribution of such Registrable Senior Notes as the Company may from time to
time reasonably require for inclusion in the registration statement.

         4.      Registration Expenses.  The Company and the Subsidiary
Guarantors will bear all expenses incurred in connection with the performance
of their obligations under Sections 1 through 3 hereof and will bear or
reimburse the holders of the Registrable Senior Notes for the reasonable fees
and disbursements of one firm of counsel designated by the holders of a
majority in principal amount of the Registrable Senior Notes to act as counsel
for the holders of the Registrable Senior Notes in connection therewith.

         5.      Indemnification.

         (a)     Indemnification by Company and the Subsidiary Guarantors.  The
Company and the Subsidiary Guarantors, jointly and severally, shall indemnify
and hold harmless (i) each Initial Purchaser, (ii) in the case of any Senior
Notes Shelf Registration, each holder of Registrable Senior Notes, and (iii) in
the case of any Registered Exchange Offer, each Broker-Dealer who holds
Exchange Notes acquired for its own account pursuant to the Exchange Offer,
and, in any such case, each Initial Purchaser's and such holder's officers,
directors, employees and agents and each person who controls each such Initial
Purchaser, now or hereafter, and each such holder within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act (each such
person being sometimes hereinafter referred to as an "Indemnified Person") from
and against any and all losses, claims, damages, liabilities and judgments
caused by any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus or in any amendment or
supplement thereto relating to the Senior Notes Shelf Registration or the
Registered Exchange Offer, as the case may be, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, except insofar as such losses,
claims, damages, liabilities or judgments are caused by any such untrue
statement or omission or allegation thereof based upon information relating to
such Indemnified Person furnished in writing





                                      -7-
<PAGE>   8
to the Company by such Indemnified Person expressly for use therein.  The
indemnity will be in addition to any liability which the Company and the
Subsidiary Guarantors may otherwise have.

                 If any action or proceeding (including any governmental
investigation or inquiry) shall be brought or asserted against an Indemnified
Person in respect of which indemnity may be sought from the Company or the
Subsidiary Guarantors, such Indemnified Person shall promptly notify the
Company and the Subsidiary Guarantors in writing, and the Company and the
Subsidiary Guarantors shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to such Indemnified Person and
the payment of all reasonable expenses.  Such Indemnified  Person shall have
the right to employ separate counsel in any such action and to participate in
the defense thereof, but the fees and expenses of such counsel shall be the
expense of such Indemnified Person unless (a) the Company and the Subsidiary
Guarantors have agreed to pay such fees and expenses or (b) the Company and the
Subsidiary Guarantors shall have failed to assume the defense of such action or
proceeding and to employ counsel reasonably satisfactory to such Indemnified
Person in any such action or proceeding within a reasonable time after notice
of commencement of such action or proceeding or (c) the named parties to any
such action or proceeding (including any impleaded parties) include such
Indemnified Person and the Company and/or the Subsidiary Guarantors, and such
Indemnified Person shall have been advised in writing by counsel that there
may be one or more legal defenses available to such Indemnified Person which
are different from or additional to those available to the Company and/or the
Subsidiary Guarantors (in which case, if  such Indemnified Person notifies the
Company and the Subsidiary Guarantors in writing that it elects to employ
separate counsel at the expense of the Company and the Subsidiary Guarantors,
the Company and the Subsidiary Guarantors shall not have the right to assume
the defense of such action or proceeding on behalf of such Indemnified Person,
it being understood, however, that the Company and the Subsidiary Guarantors
shall not, in connection with any one such action or separate but substantially
similar or related actions or proceedings in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the reasonable
fees and expenses of more than one separate firm of attorneys (in addition to
local counsel) at any time for such Indemnified Person and any other
Indemnified Persons, which firm shall be designated in writing by such
Indemnified Persons (which shall be reasonably satisfactory to the Company and
the Subsidiary Guarantors), and that all such fees and expenses shall be
reimbursed as they are billed).  The Company and the Subsidiary Guarantors
shall not be liable for any settlement of any such action or proceeding
effected without their written consent (not to be unreasonably withheld), but
if settled with their written consent, or if there be a  final, unappealable
judgment for the plaintiff in any such action or proceeding, the Company and
the Subsidiary Guarantors agree to indemnify and hold harmless such Indemnified
Persons from and against any loss or liability by reason of such settlement or
judgment.  The Company and the Subsidiary Guarantors shall not, without the
prior written consent of the Indemnified Person, effect any settlement of any
pending or threatened proceeding in respect of which any Indemnified Person is
a party and indemnity has been sought hereunder by such Indemnified Person;
provided however, that the Company and the Subsidiary Guarantors may effect
such a settlement without the consent of such Indemnified Person if such
settlement includes an unconditional release of such Indemnified Person from
all lability for claims that are the subject matter of such proceeding or the
Company and the Subsidiary Guarantors





                                      -8-
<PAGE>   9
indemnify such Indemnified Person in writing and post a bond for an amount
equal to the maximum liability for all such claims as contemplated above.

         (b)     Indemnification by Holders.  In the event of a Senior Notes
Shelf Registration, each holder of Registrable Senior Notes agrees to indemnify
and hold harmless the Company and the Subsidiary Guarantors, their directors
and officers, employees and agents and each person, if any, controlling the
Company and the Subsidiary Guarantors within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act to the same extent as
the foregoing indemnity from the Company to such holder, but only with respect
to information relating to such holder or the distribution furnished in writing
by such holder expressly for use in any registration statement or prospectus or
any amendment or supplement thereto or any preliminary prospectus relating to
the Senior Notes Shelf Registration, provided, however, that no such holder
shall be liable for any indemnity claims hereunder in excess of the amount of
net proceeds received by such holder from the sale of Registrable Senior Notes
pursuant to the Senior Notes Shelf Registration.  If any action or proceeding
shall be brought against the Company, the Subsidiary Guarantors or their
directors, officers, employees or agents or any such controlling person, in
respect of which indemnity may be sought against a holder of Registrable Senior
Notes, such holder shall have the rights and duties given the Company and the
Subsidiary Guarantors and the Company and the Subsidiary Guarantors or their
directors, officers, employees or agents or such controlling person shall have
the rights and duties given to each holder by Section 5(a) hereof.  The Company
and the Subsidiary Guarantors shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in the distribution, to the same extent as provided
above with respect to information so furnished in writing by such persons
specifically for inclusion in any prospectus or registration statement or any
amendment or supplement thereto.

         (c)     Contribution.   If the indemnification provided for in this
Section 5 is unavailable to an indemnified party under Section 5(a) or Section
5(b) hereof (other than by reason of exceptions provided in those Sections) in
respect of any losses, claims, damages, liabilities or judgments referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
judgments in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and the Subsidiary
Guarantors on the one hand and of the Indemnified Person on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations.  The relative fault of the Company and the Subsidiary
Guarantors on the one hand and of the Indemnified Person on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company and the
Subsidiary Guarantors or by the Indemnified Person and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The amount paid or payable by a party as a result
of the losses, claims, damages, liabilities and expenses referred to above
shall be deemed to include, subject to the





                                      -9-
<PAGE>   10
limitations set forth in the second paragraph of Section 5(a), any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim.

                 The Company, the Subsidiary Guarantors and the holders of the
Registrable Senior Notes and Exchange Notes agree that it would not be just and
equitable if contribution pursuant to this Section 5(c) were determined by pro
rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately
preceding paragraph.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                 6.       Additional Interest Under Certain Circumstances;
Remedies.

                 If the Company and the Subsidiary Guarantors fail to file
within 60 days, or cause to become effective within 160 days, the registration
statement relating to the Registered Exchange Offers or the Senior Notes Shelf
Registration, as applicable, or (subject to Section 2(b)) the Senior Notes
Shelf Registration is declared effective but thereafter ceases to be effective
in connection with resales of the Registrable Senior Notes (each such event, a
"Registration Default"), then the Company agrees to pay to each holder of
Registrable Senior Notes of the applicable issue, accruing from the date of the
first such Registration Default, liquidated damages in an amount equal to
one-half of one percent (0.5%) per annum of the principal amount of Registrable
Senior Notes held by such holder during the first 160-day period immediately
following the occurrence of the first such Registration Default, increasing by
an additional one-half of one percent (0.5%) per annum of the principal amount
of such Registrable Senior Notes during each subsequent 160-day period, up to a
maximum amount of liquidated damages equal to two percent (2.0%) per annum of
the principal amount of such Registrable Senior Notes ("Senior Notes Liquidated
Damages"), and ceasing to accrue on the date such Registration Default has been
cured by, as applicable, the filing, declaration of effectiveness or withdrawal
of suspension of effectiveness of the applicable registration statement.  The
Company shall notify the Trustee within one business day after (i) each and
every Registration Default and (ii) the date the Registration Default has been
so cured.  Until the Trustee and the Paying Agent have received an Officers'
Certificate from the Company to the effect that all Senior Notes Liquidated
Damages then due have been paid in full, the Company (in respect of any payment
date) shall pay Senior Notes Liquidated Damages then due by depositing with the
Trustee, in trust, for the benefit of the affected holders of Registrable
Senior Notes, on or before the applicable semi-annual interest payment date,
immediately available funds in sums sufficient to pay the liquidated damages
then due and provide to the Trustee and the Paying Agent a list of holders
entitled to Senior Notes Liquidated Damages together with the amount of cash
such holder is due.  The Senior Notes Liquidated Damages amount due shall be
payable as additional interest (from funds received pursuant to such deposit)
on each interest payment date to the record holder and Registrable Senior Notes
entitled to receive the interest payment to be made on such date as set forth
in the Indenture.

                             S-4

Ladies and Gentlemen:

                 Reference is made to the above-captioned registration
statement (the "Registration Statement") to be filed with the Securities and
Exchange Commission by Chesapeake Energy Corporation (the "Company") and its
subsidiaries Chesapeake Operating, Inc., Chesapeake Gas Development Corporation
and Chesapeake Exploration Limited Partnership (the "Subsidiary Guarantors")
with respect to (a) $150 million principal amount of 7 7/8% Series B Senior
Notes due 2004 ("New Notes due 2004") of the Company to be offered in exchange
for $150 million principal amount of its outstanding 7 7/8% Series A Senior
Notes due 2004 ("Old Notes due 2004") and (b) $150 million principal amount of
8 1/2% Series B Senior Notes due 2012 ("New Notes due 2012") of the Company to
be offered in exchange for $150 million principal amount of its outstanding 8
1/2% Series A Senior Notes due 2012 ("Old Notes due 2012").  The Old Notes due
2004 were, and the New Notes due 2004 will be, issued pursuant to the Indenture
dated as of March 15, 1997 among the Company, as issuer, the Subsidiary
Guarantors, as guarantors, and United States Trust Company of New York ("U.S.
Trust"), as trustee (the "Notes due 2004 Indenture"), which will be filed as
Exhibit 4.1 to the Registration Statement.  The Old Notes due 2012 were, and
the New Notes due 2012 will be, issued pursuant to the Indenture dated as of
March 15, 1997 among the Company, as issuer, the Subsidiary Guarantors, as
guarantors, and U.S. Trust, as trustee (the "Notes due 2012 Indenture"), which
will be filed as Exhibit 4.3 to the Registration Statement.  The New Notes due
2004 and the New Notes due 2012 are referred to, collectively, as the "New
Notes," and the Notes due 2004 Indenture and the Notes due 2012 Indenture are
referred to, together, as the "Indentures."

                 We have examined the Indentures, the forms of certificate
which will evidence the New Notes (the "Certificates"), and certain corporate
records of the Company, and we have made such other

investigations as we have deemed appropriate in order to express the opinion
set forth herein.

                 Based upon the foregoing, we are of the opinion that:

                 1.       The Company is a corporation duly organized and
validly existing under the laws of the State of Oklahoma; and

                 2.       The Indentures, the New Notes, and the guarantees of
the New Notes by the Subsidiary Guarantors (the "Guarantees") have been duly
and validly authorized, and the New Notes and Guarantees, when issued in
accordance with the terms of the respective Indentures, will constitute binding
obligations of the Company and the Subsidiary Guarantors, enforceable against
the Company and the Subsidiary Guarantors in accordance with the terms of the
Indentures and the Certificates, subject to (a) applicable bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and similar laws
relating to creditors' rights and remedies generally and (b) general principles
of equity (whether enforcement is sought in a proceeding at law or in equity).

                 While each of the Indentures provides that it will be governed
by the substantive laws of the State of New York, we have assumed, for purposes
of our opinion, that the Indentures will be governed by the laws of the State
of Oklahoma.

                 We hereby consent to the inclusion of this opinion as an
exhibit to the Registration Statement and to the reference to our firm under
the caption "Legal Matters" in the Prospectus which is a part of the
Registration Statement.



                                        Very truly yours,

                                        McAFEE & TAFT A PROFESSIONAL

         DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET
FORTH ABOVE OR TRANSMISSION OF INSTRUCTIONS VIA A FACSIMILE TRANSMISSION TO A
NUMBER OTHER THAN AS SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

         The undersigned acknowledges receipt of the Prospectus dated        ,
1997 (the "Prospectus") of Chesapeake Energy Corporation ("Chesapeake") which,
together with this Letter of Transmittal (the "Letter of Transmittal"),
constitutes Chesapeake's offer (the "Exchange Offer") to exchange $1,000 in
principal amount of a new series of [7 7/8% Series B Senior Notes Due 2004][8
1/2% Series B Senior Notes Due 2012] (the "New Notes") of Chesapeake for each
$1,000 in principal amount of outstanding [7 7/8% Series A Senior Notes Due
2004][8 1/2% Series A Senior Notes Due 2012] (the "Old Notes") of Chesapeake.
The terms of the New Notes are identical in all material respects (including
principal amount, interest rate and maturity) to the terms of the Old Notes for
which they may be exchanged pursuant to the Exchange Offer, except that the New
Notes will have been registered under the Securities Act of 1933, as amended,
and, therefore, will not bear legends restricting the transfer thereof.

         The Exchange Offer is being made pursuant to the Registration Rights
Agreement dated as of March 12, 1997 (the "Registration Rights Agreement"), and
all Old Notes validly tendered will be accepted for exchange.  Any Old Notes
not tendered will remain outstanding and continue to accrue interest, but will
not retain any rights under the Registration Rights Agreement. Holders electing
to have Old Notes exchanged pursuant to the Exchange Offer will be required to
surrender such Old Notes,
<PAGE>   2
together with the Letter of Transmittal, to the Exchange Agent at the address
specified herein prior to the close of business on the Expiration Date.
Holders will be entitled to withdraw their election, at any time prior to 5:00
p.m., New York City time on the Expiration Date, by sending to the Exchange
Agent at the address specified herein a facsimile transmission or letter
setting forth the name of such Holder, the principal amount of Old Notes
delivered for exchange and a statement that such Holder is withdrawing this
election to have such Old Notes exchanged.

         The undersigned has checked the appropriate boxes below and signed
this Letter of Transmittal to indicate the action the undersigned desires to
take with respect to the Exchange Offer.

         PLEASE READ THE ENTIRE LETTER OF TRANSMITTAL AND THE PROSPECTUS
CAREFULLY BEFORE CHECKING ANY BOX BELOW.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offer,
the undersigned hereby tenders to Chesapeake the above-described principal
amount of Old Notes. Subject to, and effective upon, the acceptance for
exchange of the Old Notes tendered herewith, the undersigned hereby exchanges,
assigns and transfers to, or upon the order of, Chesapeake all right, title and
interest in and to such Old Notes. The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent as the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that said Exchange
Agent acts as the agent of the undersigned in connection with the Exchange
Offer) to cause the Old Notes to be assigned, transferred and exchanged. The
undersigned represents and warrants that it has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire New Notes
issuable upon the exchange of such tendered Old Notes, and that, when the same
are accepted for exchange, Chesapeake will acquire good and unencumbered title
to the tendered Old Notes, free and clear of all liens, restrictions, charges
and encumbrances and not subject to any adverse claim. The undersigned also
warrants that it will, upon request, execute and deliver any additional
documents deemed by Chesapeake to be necessary or desirable to complete the
exchange, assignment and transfer of tendered Old Notes or to transfer
ownership of such Old Notes on the account books maintained by The Depository
Trust Company.

         The Exchange Offer is subject to certain conditions as set forth in
the Prospectus under the caption "The Exchange Offer -- Conditions of the
Exchange Offer." The undersigned recognizes that as a result of these
conditions (which may be waived, in whole or in part, by Chesapeake) as more
particularly set forth in the Prospectus, Chesapeake may not be required to
exchange any of the Old Notes tendered hereby and, in such event, the Old Notes
not exchanged will be returned to the undersigned at the address shown below
the signature of the undersigned.

         By tendering, each Holder of Old Notes represents to Chesapeake that
(i) the New Notes acquired pursuant to the Exchange Offer are being obtained in
the ordinary course of business of the person receiving such New Notes, whether
or not such person is such Holder, (ii) neither the Holder of Old Notes nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such New Notes, (iii) if the Holder is not a
broker- dealer or is a broker-dealer but will not receive New Notes for its own
account in exchange for Old Notes, neither the Holder nor any such other person
is engaged in or intends to participate in a distribution of the New Notes and
(iv) neither the Holder nor any such other person is an "affiliate" of
Chesapeake within the meaning of Rule 405 under the Securities Act of 1933, as
amended (the "Securities Act") or, if such Holder is an "affiliate," that such
Holder will comply with the registration and prospectus delivery requirements
of the Securities Act to the extent applicable. If the tendering Holder is a
broker-dealer (whether or not it is also an "affiliate" of Chesapeake within
the meaning of Rule 405 under the Securities Act) that will receive New Notes
for its own account in exchange for Old Notes, it acknowledges that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Notes. By acknowledging that it will

                                  INSTRUCTIONS

                    FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER

         1.      DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.
Certificates for all physically delivered Old Notes, as well as a properly
completed and duly executed copy of this Letter of Transmittal or facsimile
thereof, and any other documents required by this Letter of Transmittal, must
be received by the Exchange Agent at any of its addresses set forth herein on
or prior to the Expiration Date.

         THE METHOD OF DELIVERY OF OLD NOTES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. INSTEAD OF
DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND
DELIVERY SERVICE.

         Holders whose Old Notes are not immediately available or who cannot
deliver their Old Notes and all other required documents to the Exchange Agent
on or prior to the Expiration Date may tender their Old Notes pursuant to the
guaranteed delivery procedure set forth in the Prospectus under "The Exchange
Offer -- Terms of the Exchange Offer -- Guaranteed Delivery Procedures."
Pursuant to such procedure: (i) such tender must be made by or through an
Eligible Institution (as defined in the Prospectus); (ii) on or prior to the
Expiration Date, the Exchange Agent must have received from such Eligible
Institution a letter, telegram or facsimile transmission setting forth the name
and address of the tendering Holder, the name(s) in which such Old Notes are
registered, and the certificate number(s) of the Old Notes to be tendered; and
(iii) all tendered Old Notes as well as this Letter of Transmittal and all
other documents required by this Letter of Transmittal must be received by the
Exchange Agent within three New York Stock Exchange trading days after the date
of execution of such letter, telex, telegram or facsimile transmission, all as
provided in the Prospectus under the caption "The Exchange Offer -- Terms of
the Exchange Offer -- Guaranteed Delivery Procedures."

         No alternative, conditional, irregular or contingent tenders will be
accepted.  All tendering Holders, by execution of this Letter of Transmittal
(or facsimile thereof), shall waive any right to receive notice of the
acceptance of the Old Notes for exchange.

         2.      PARTIAL TENDERS; WITHDRAWALS.  Tenders of Old Notes will be
accepted in denominations of $1,000 and integral multiples in excess thereof.
If less than the entire principal amount of Old Notes evidenced by a submitted
certificate is tendered, the tendering Holder must fill in the principal amount
tendered in the column entitled "Principal Amount Tendered."  A newly issued
certificate for the principal amount of Old Notes submitted but not tendered
will be sent to such Holder as soon as practicable after the Expiration Date.
All Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.  To withdraw a tender of Old Notes in the
Exchange Offer, a written or facsimile transmission notice of withdrawal must
be received by the Exchange Agent at its address set forth herein prior to 5:00
p.m., New York City time, on the Expiration Date. Any such notice of withdrawal
must (i) specify the name of the person having deposited the Old Notes to be
withdrawn (the "Depositor"), (ii) identify the Old Notes to be withdrawn
(including the certificate number or numbers and principal amount of such Old
Notes), (iii) contain a statement that such holder is withdrawing its election
to have such Old Notes exchanged, (iv) be signed by the Holder in the same
manner as the original signature on the Letter of Transmittal by which such Old
Notes were tendered (including any required signature





                                      -7-
<PAGE>   8
guarantees) or be accompanied by documents of transfer sufficient to have the
Trustee with respect to the Old Notes register the transfer of such Old Notes
in the name of the person withdrawing the tender and (v) specify the name in
which any such Old Notes are to be registered, if different from that of the
Depositor. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the book-entry transfer facility. All questions as to the
validity, form and eligibility (including time of receipt) of such notices will
be determined by Chesapeake, whose determination shall be final and binding on
all parties. Any Old Notes so withdrawn will be deemed not to have been validly
tendered for purposes of the Exchange Offer and no New Notes will be issued
with respect thereto unless the Old Notes so withdrawn are validly retendered.
Any Old Notes which have been tendered but which are not accepted for exchange
will be returned to the Holder thereof without cost to such Holder as soon as
practicable after withdrawal, rejection of tender or termination of the
Exchange Offer.  Properly withdrawn Old Notes may be retendered by following
one of the procedures described herein at any time prior to the business day
prior to the Expiration Date.

         3.      SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS
AND ENDORSEMENTS; GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is
signed by the registered Holder(s) of the Old Notes tendered hereby, the
signature must correspond with the name(s) as written on the face of
certificates without alteration, enlargement or any change whatsoever.

         If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are
to be issued (and any untendered Old Notes are to be reissued) in the name of
the registered holder (including any participant in The Depository Trust
Company (also referred to as a book-entry facility) whose name appears on a
security listing as the owner of Old Notes), the signature of such signer need
not be guaranteed. In any other case, the tendered Old Notes must be endorsed
or accompanied by written instruments of transfer in form satisfactory to
Chesapeake and duly executed by the registered holder and the signature on the
endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion
Program (SEMP).

         If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be
guaranteed by an Eligible Institution.

         Endorsements on certificates or signatures on separate written
instruments of transfer or exchange required by this Instruction 3 must be
guaranteed by an Eligible Institution.

         If any of the Old Notes tendered hereby are owned of record by two or
more joint owners, all such owners must sign this Letter of Transmittal.

         If a number of Old Notes registered in different names are tendered,
it will be necessary to complete, sign and submit as many separate copies of
this Letter of Transmittal as there are different registrations of Old Notes.





                                      -8-
<PAGE>   9
         When this Letter of Transmittal is signed by the registered Holder or
Holders of Old Notes listed and tendered hereby, no endorsements of
certificates or separate written instruments of transfer or exchange are
required.

         If this Letter of Transmittal is signed by a person other than the
registered Holder or Holders of the Old Notes listed, such Old Notes must be
endorsed or accompanied by separate written instruments of transfer or exchange
in form satisfactory to Chesapeake and duly executed by the registered Holder
or Holders, in either case signed exactly as the name or names of the
registered Holder or Holders appear(s) on the Old Notes.

         If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or
others acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by Chesapeake, proper evidence
satisfactory to Chesapeake of their authority so to act must be submitted.

         4.      TRANSFER TAXES.  Chesapeake shall pay all transfer taxes, if
any, applicable to the exchange of Old Notes pursuant to the Exchange Offer.
If, however, certificates representing New Notes, or Old Notes for principal
amounts not tendered or accepted for exchange, are to be delivered to, or are
to be issued in the name of, any person other than the registered Holder of the
Old Notes tendered hereby, or if a transfer tax is imposed for any reason other
than the exchange of Old Notes pursuant to the Exchange Offer, then the amount
of any such transfer taxes (whether imposed on the registered Holder or any
other person) will be payable by the tendering Holder.  If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted
herewith, the amount of such transfer taxes will be billed directly to such
tendering Holder.

         Except as provided in this Instruction 4, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.

         5.      WAIVER OF CONDITIONS.  Chesapeake reserves the absolute right
to waive, in whole or in part, any of the conditions to the Exchange Offer set
forth in the Prospectus.

         6.      MUTILATED, LOST, STOLEN OR DESTROYED NOTES.  Any Holder whose
Old Notes have been mutilated, lost, stolen or destroyed should contact the
Exchange Agent at the address indicated above for further instructions.

         7.      REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions
relating to the procedure for tendering and other questions relating to the
Exchange Offer, as well as requests for assistance or additional copies of the
Prospectus and this Letter of Transmittal, may be directed to the Exchange
Agent at the address and telephone number set forth above and in the
Prospectus.

         8.      IRREGULARITIES.  All questions as to the validity, form,
eligibility (including time of receipt), and acceptance of Letters of
Transmittal or Old Notes will be resolved by Chesapeake, whose determination
will be final and binding.  Chesapeake reserves the absolute right to reject
any or all Letters of Transmittal or tenders that are not in proper form or the
acceptance of which would, in the opinion of Chesapeake's counsel, be unlawful.
Chesapeake also reserves the right to waive any irregularities or conditions of
tender as to the particular Old Notes covered by any Letter of Transmittal or
tendered pursuant to such Letter of Transmittal.  None of Chesapeake, the
Exchange Agent or any other person will be under any duty to





                                      -9-
<PAGE>   10
give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification.  Chesapeake's
interpretation of the terms and conditions of the Exchange Offer shall be final
and binding.

         9.      DEFINITIONS.  Capitalized terms used in this Letter of
Transmittal and not otherwise defined have the meanings given in the
Prospectus.


         IMPORTANT:  THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF
(TOGETHER WITH CERTIFICATES FOR OLD NOTES AND ALL OTHER REQUIRED DOCUMENTS) OR
A NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR
