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 ended March 31, 1998 are not necessarily
indicative of the results to be expected for the full fiscal year.

The Company has changed its fiscal year end from June 30 to December 31. This
Form 10-Q relates to the three months ended March 31, 1998 (the "Current
Quarter") and March 31, 1997 (the "Prior Quarter").

2. RECENT ACQUISITIONS

On December 16, 1997, the Company acquired AnSon Production Corporation
("AnSon"), a privately owned oil and gas producer based in Oklahoma City.
Consideration for the acquisition was approximately $43 million, which included
the issuance of 3,792,724 shares of Chesapeake's common stock and the payment
of $24.8 million on May 7, 1998, pursuant to a make-whole provision.

On January 30, 1998, the Company entered into a 40/60 alliance with Ranger Oil
Limited to jointly develop a 3.2 million acre area of mutual interest in the
Helmet area of northeastern British Columbia. As part of the transaction, the
Company paid approximately $48 million for proved oil and gas reserves,
undeveloped leasehold and a 40% interest in Ranger's infrastructure in the area.

On February 6, 1998, the Company purchased the Mid-Continent properties of 
EnerVest Management Company, L.L.C. for $38 million.

On March 10, 1998, the Company acquired Hugoton Energy Corporation ("Hugoton")
pursuant to a merger by issuing approximately 25.8 million shares of the
Company's common stock in exchange for 100% of Hugoton's common stock.
See Consolidated Statements of Cash Flows.

On April 22, 1998, the Company issued $230 million (4.6 million shares) of its
7% Cumulative Convertible Preferred Stock, $50 per share liquidation preference,
and $500 million of its 9.625% Series A Senior Notes due 2005. Net proceeds from
these offerings were approximately $712 million.

On April 27, 1998, the Company acquired from Gothic Energy Corporation certain
proved oil and gas reserves for $20 million, purchased $50 million of Gothic 12%
preferred stock, acquired ten-year warrants to purchase 15% of Gothic's
currently outstanding common stock for $0.01 per share, acquired a 50% interest
in Gothic's undeveloped leasehold acreage and entered into a five-year drilling
and acquisitions participation agreement. 

On April 27, 1998, Chesapeake acquired the British Columbia properties of
Sunoma Energy Corporation for $33 million.

On April 28, 1998 the Company acquired by merger the Mid-Continent operations of
DLB Oil & Gas, Inc. for $17.5 million in cash, 5,000,000 shares of the Company's
common stock, and the assumption of $90 million in outstanding debt and working
capital obligations.

On April 30, 1998, the Company acquired 100% of the stock of MC Panhandle Corp.,
a wholly-owned subsidiary of Occidental Petroleum Corporation, by paying
approximately $95 million, net of working capital adjustments.

Effective April 30, 1998, the Company purchased all of its outstanding 10.5%
Senior Notes due 2002. Of the $90,000,000 aggregate principal amount,
$89,830,000 was acquired pursuant to the Company's offer to purchase, which
commenced April 1, 1998, and the remaining $170,000 was acquired on the same
terms after the tender period. The cost to acquire the 10.5% Senior Notes was
approximately $99,000,000.  The early retirement of these notes will result in
an extraordinary charge of approximately $12 million during the quarter ended
June 30, 1998.

3. LEGAL PROCEEDINGS

The Company and certain of its officers and directors are defendants in a
consolidated class action suit alleging violations of the Securities Exchange
Act of 1934. The plaintiffs assert that the defendants made material
misrepresentations and failed to disclose material facts about the success of
the Company's exploration efforts in the Louisiana Trend. As a result, the
complaint alleges the price of the Company's common stock was artificially
inflated from January 25, 1996 until June 27, 1997, when the Company issued a
press release announcing disappointing drilling results in the Louisiana Trend
and a full-cost ceiling writedown to be reflected in its June 30, 1997 financial
statements. The plaintiffs further allege that certain of the named individual
defendants sold common stock during the class period when they knew or should
have known adverse nonpublic information. The plaintiffs seek a determination
that the suit is a proper class action and damages in an unspecified amount,
together with interest and costs of litigation, including attorneys' fees. The
Company and the individual defendants believe that these claims are without
merit, and intend to defend against them vigorously. No estimate of loss or
range of estimate of loss, if any, can be made at this time.

Various purported class actions alleging violations of the Securities Act of
1933 and the Oklahoma Securities Act have been filed against the Company and
others on behalf of investors who purchased common stock of Bayard Drilling
Technologies, Inc. ("Bayard") in its initial public offering in November 1997.
In May 1998, the plaintiffs in the two cases pursuing state claims dismissed
their state court suits and became co-lead plaintiffs in the remaining federal
case. Total proceeds of the offering were $254 million, of which the Company
received net proceeds of $90.2 million. Plaintiffs allege that the Company, a
major customer of Bayard's drilling services and the owner of 30.1% of Bayard's
common stock outstanding prior to the offering, was a controlling person of
Bayard. Plaintiffs assert that the Bayard prospectus contained material
omissions and misstatements relating to (i) the Company's financial "hardships"
and their significance on Bayard's business, (ii) increased costs associated
with Bayard's growth strategy, and (iii) undisclosed pending related-party
transactions between Bayard and third parties other than the Company. The
alleged defective disclosures are claimed to have resulted in a decline in
Bayard's share price following the public offering. The plaintiffs seek a
determination that the suit is a proper class action and damages in an
unspecified amount or rescission, together with interest and costs of
litigation, including attorney's fees. The Company believes that the claims are
without merit and intends to defend against them vigorously. No estimate of loss
or range of estimate of loss, if any, can be made at this time.

In October 1996, Union Pacific Resources Company ("UPRC") sued the Company
alleging infringement of a patent for a drilling method, tortious interference
with confidentiality contracts between UPRC and certain of its former employees
and misappropriation of proprietary information of UPRC. UPRC's claims against
the Company are based on services provided to the Company by a third party
vendor controlled by former UPRC employees. UPRC is seeking injunctive relief,
damages of an unspecified amount, including actual, enhanced, consequential and
punitive damages, interest, costs and attorneys' fees. The Company believes that
it has meritorious defenses to UPRC's allegations and has requested the court to
declare the UPRC patent invalid. The Company has also filed a motion to construe
UPRC's patent claims and various motions for summary judgment. No estimate of
loss or range of estimate of loss, if any, can be made at this time; however, in
reports filed in the proceeding, experts for UPRC

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (UNAUDITED)


claim that damages could be as much as $18 million while Company experts state
that the amount should not exceed $25,000, in each case based on a reasonable
royalty.

The Company is currently involved in various other 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 such 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.

4. IMPAIRMENT OF OIL AND GAS PROPERTIES

The Company incurred an impairment of oil and gas properties charge of $250
million in the Current Quarter. This writedown was caused by several factors,
including the effects of accounting for the Hugoton acquisition using the 
purchase accounting method, oil prices declining from $17.62 at December 31,
1997 to $13.92 at March 31, 1998, gas prices declining from $2.29 at December
31, 1997 to $2.01 at March 31, 1998 and higher drilling and completion costs
compared to previous estimates. Additionally, lower oil and gas prices at March
31, 1998 and higher drilling costs caused downward revisions in the Company's
proved reserves as certain proved undeveloped reserves previously estimated by
the Company were rendered uneconomic and therefore excluded by the Company from
its proved reserves.

The primary reason for the impairment charge was the completion of the
acquisition in March 1998 of Hugoton, which was accounted for using the purchase
method. The purchase price, which was established in November 1997 when the
acquisition was announced (based on a Chesapeake common stock price of $8.00 per
share), was allocated almost entirely to Hugoton's evaluated oil and gas
properties. Based upon reserve estimates as of March 31, 1998, the portion of
the purchase price which was allocated to evaluated oil and gas properties
exceeded the associated discounted future net revenues from Hugoton's estimated
proved reserves by approximately $150 million.

5. NET INCOME (LOSS) PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, Earnings Per Share ("SFAS 128"). SFAS
128 requires presentation of "basic" and "diluted" earnings per share, as
defined, on the face of the statement of operations for all entities with
complex capital structures. SFAS 128 is effective for financial statements
issued for periods ending after December 15, 1997 and requires restatement of
all prior period earnings per share amounts. The Company has adopted SFAS 128
and has restated all prior periods presented.

SFAS 128 requires a reconciliation of the numerators and denominators of the
basic and diluted EPS computations. For the Current Quarter there was no
difference between actual weighted average shares outstanding, which are used in
computing basic EPS and diluted weighted average shares, which are used in
computing diluted EPS. Options to purchase 10.2 million shares of common stock
at a weighted average exercise price of $5.69 were outstanding during the
Current Quarter but were not included in the computation of diluted EPS because
the effect of these outstanding options would be antidilutive. A reconciliation
for the Prior Quarter is as follows:

Subsidiaries is a direct or indirect wholly-owned subsidiary of the Company.

limiting the Company and the Guarantor Subsidiaries 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,

mergers or consolidations, and transactions with affiliates. The Company is
obligated to repurchase the 9.125% Senior Notes in the event of a change of
control or certain asset sales.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS

RECENT EVENTS

On December 16, 1997, the Company acquired AnSon Production Corporation
("AnSon"), a privately owned oil and gas producer based in Oklahoma City.
Consideration for the acquisition was approximately $43 million, which included 
the issuance of 3,792,724 shares of Chesapeake's common stock and the payment of
$24.8 million on May 7, 1998, pursuant to a make-whole provision.

On January 30, 1998, the Company entered into a 40/60 alliance with Ranger Oil
Limited to jointly develop a 3.2 million acre area of mutual interest in the
Helmet area of northeastern British Columbia. As part of the transaction, the
Company paid approximately $48 million for proved oil and gas reserves,
undeveloped leasehold and a 40% interest in Ranger's infrastructure in the area.

On February 6, 1998, the Company purchased the Mid-Continent properties of 
EnerVest Management Company, L.L.C. for $38 million.

On March 10, 1998, the Company acquired Hugoton Energy Corporation ("Hugoton")
pursuant to a merger by issuing approximately 25.8 million shares of the
Company's common stock in exchange for 100% of Hugoton's common stock.
See Consolidated Statements of Cash Flows.

On April 22, 1998, the Company issued $230 million (4.6 million shares) of its
7% Cumulative Convertible Preferred Stock, $50 per share liquidation preference,
and $500 million of its 9.625% Series A Senior Notes due 2005. Net proceeds from
these offerings were approximately $712 million.

On April 27, 1998, the Company acquired from Gothic Energy Corporation certain
proved oil and gas reserves for $20 million, purchased $50 million of Gothic 12%
preferred stock, acquired ten-year warrants to purchase 15% of Gothic's
currently outstanding common stock for $0.01 per share, acquired a 50% interest
in Gothic's undeveloped leasehold acreage and entered into a five-year drilling
and acquisitions participation agreement.

On April 27, 1998, Chesapeake acquired the British Columbia properties of
Sunoma Energy Corporation for $33 million. 

On April 28, 1998, the Company acquired by merger the Mid-Continent operations
of DLB Oil & Gas, Inc. for $17.5 million in cash, 5,000,000 shares of the
Company's common stock, and the assumption of $90 million in outstanding debt
and working capital obligations.

On April 30, 1998, the Company acquired 100% of the stock of MC Panhandle Corp.,
a wholly-owned subsidiary of Occidental Petroleum Corporation, by paying 
approximately $95 million, net of working capital adjustments.

Effective April 30, 1998, the Company purchased all of its outstanding 10.5%
Senior Notes due 2002. Of the $90,000,000 aggregate principal amount,
$89,830,000 was acquired pursuant to the Company's offer to purchase, which
commenced April 1, 1998, and the remaining $170,000 was acquired on the same
terms after the tender period. The cost to acquire the 10.5% Senior Notes was
approximately $99,000,000. The early retirement of these notes will result in an
extraordinary charge of approximately $12 million during the quarter ended June
30, 1998.

RESULTS OF OPERATIONS - Three months ended March 31, 1998 vs. March 31, 1997

General. For the three months ended March 31, 1998 (the "Current Quarter"), the
Company realized a net loss of $256.5 million, or $3.19 per common share. This
compares to net income of $15.9 million, or $0.22 per common share, in the three
months ended March 31, 1997 (the "Prior Quarter"). The loss in the Current
Quarter was primarily caused by a $250.0 million asset writedown recorded under
the full-cost method of accounting and, to a much lesser extent, a $6.5 million
loss from recurring operations. The asset writedown was primarily caused by the
Hugoton acquisition in March 1998 for consideration in excess of the present
value (10% discount) of the future net revenues of the proved reserves acquired
as of March 31, 1998 (approximately $150 million of the writedown) and by
decreases in oil and gas prices from December 31, 1997 to March 31, 1998. See
Impairment of Oil and Gas Properties. No such writedown occurred in the Prior
Quarter.

Oil and Gas Sales. During the Current Quarter, oil and gas sales decreased 13%
to $50.2 million from $57.4 million in the Prior Quarter. The decrease resulted
from significantly lower oil and gas prices, partially offset by a 12% increase
in production volumes. For the Current Quarter, the Company produced 23.0
billion cubic feet equivalent ("bcfe"), consisting of 1.2 million barrels of oil
("mmbo") and 16 billion cubic feet of natural gas ("bcf"), compared to 0.8 mmbo
and 15.7 bcf, or 20.5 bcfe, in the Prior Quarter. Average oil prices realized
were $14.84 per barrel of oil ("bo") in the Current Quarter compared to $21.55
in the Prior Quarter, a decrease of 31%. Average gas prices realized were $2.06
per thousand cubic feet ("mcf") in the Current Quarter compared to $2.55 per mcf
in the Prior Quarter, a decrease of 19%.

For the Current Quarter, the Company realized an average price of $2.19 per
thousand cubic feet equivalent ("mcfe"), compared to $2.79 per mcfe in the Prior
Quarter. The Company's hedging activities resulted in increased oil and gas
revenues of $1.8 million, or $0.08 per mcfe, in the Current Quarter, compared to
decreases in oil and gas revenues of $0.2 million, or $0.01 per mcfe, in the
Prior Quarter.

The following table shows the Company's production by region for the Current
Quarter and the Prior Quarter:

</TABLE>


Natural gas production represented approximately 69% of the Company's total
production volume on an equivalent basis in the Current Quarter, compared to 77%
in the Prior Quarter. This decrease in natural gas production as a percentage of
total production was primarily the result of new production in the Louisiana
portion of the Austin Chalk Trend, which tends to produce more oil than gas. The
Company anticipates that as a result of its recent acquisitions, increased
drilling in the Mid-Continent and Canada and decreased drilling in Louisiana,
natural gas will represent 70-75% of anticipated 1998 production.

Oil and Gas Marketing Sales. The Company realized $26.5 million in oil and gas
marketing sales for third parties in the Current Quarter, with corresponding oil
and gas marketing expenses of $26.3 million, for a margin of $0.2 million. This
compares to sales of $22.4 million, expenses of $21.7 million, and a margin of
$0.7 million in the Prior Quarter. The Company anticipates gross margins will
increase during 1998 as a result of the acquisition of certain gas gathering,
transportation and marketing assets completed in 1998.

Interest and Other. Interest and other revenues for the Current Quarter were
$0.2 million compared to $3.3 million in the Prior Quarter. The decrease was
primarily caused by the Company maintaining lower invested cash balances
resulting in reduced interest income.



                                       16
<PAGE>   17


Production Expenses and Taxes. Production expenses increased to $7.9 million in
the Current Quarter, a $4.7 million increase from the $3.2 million incurred in
the Prior Quarter. On a production unit basis, production expenses were $0.34
and $0.16 per mcfe in the Current and Prior Quarters, respectively. The primary
reason for the increase in production expenses was the increased lifting costs
associated with the Louisiana production, which represented a higher proportion
of production in the Current Quarter than the Prior Quarter. Also contributing
to the increase was the addition of production obtained in the Hugoton and AnSon
acquisitions, which typically has higher production expense per Mcfe of
production than the Company's historical production base. The Company
anticipates production expenses will continue to rise during 1998 as the result
of additional acquisitions closed in April 1998, and expects production expenses
to average $0.35 to $0.40 per mcfe for 1998.

Production taxes, which consist primarily of wellhead severance taxes, were
$1.5 million and $1.2 million in the Current and Prior Quarters, respectively.
This increase, from $0.06 per mcfe to $0.07 per mcfe, was the result of the
higher tax rates associated with production obtained in the acquisitions as
compared to the Company's historical production base.

Impairment of Oil and Gas Properties. The Company utilizes the full-cost method
to account for its investments in oil and gas properties. Under this method, all
costs of acquisition, exploration and development of oil and gas reserves
(including such costs as leasehold acquisition costs, geological and geophysical
expenditures, certain capitalized internal costs, dry hole costs and tangible
and intangible development costs) are capitalized as incurred. These oil and gas
property costs, including the estimated future capital expenditures to develop
the proved undeveloped reserves, are depleted and charged to operations using
the unit-of-production method based on the ratio of current production to proved
oil and gas reserves as estimated by the Company's independent engineering
consultants and Company engineers. Costs directly associated with the
acquisition and evaluation of unproved properties are excluded from the
amortization computation until it is determined whether or not proved reserves
can be assigned to the property or whether impairment has occurred. To the
extent that capitalized costs of oil and gas properties, net of accumulated
depreciation, depletion and amortization and related deferred income taxes,
exceed the discounted future net revenues of proved oil and gas properties, such
excess costs are charged to operations.

The Company incurred an impairment of oil and gas properties charge of $250
million in the Current Quarter, compared to no impairment in the Prior Quarter.
This writedown was caused by several factors, including the Hugoton acquisition,
oil prices declining from $17.62 at December 31, 1997 to $13.92 at March 31,
1998, gas prices declining from $2.29 at December 31, 1997 to $2.01 at March 31,
1998 and higher drilling and completion costs compared to previous estimates.
Additionally, lower oil and gas prices at March 31, 1998 and higher drilling
costs caused downward revisions in the Company's proved reserves as certain
proved undeveloped reserves previously estimated by the Company were rendered
uneconomic and therefore not included in the Company's evaluation of its proved
reserves.

The primary reason for the impairment charge was the completion of the
acquisition in March 1998 of Hugoton, which was accounted for using the purchase
method. The purchase price, which was established in November 1997 when the
acquisition was announced (based on a Chesapeake common stock price of $8.00 per
share), was allocated almost entirely to Hugoton's evaluated oil and gas
properties. Based upon reserve estimates as of March 31, 1998, the portion of
the purchase price which was allocated to evaluated oil and gas properties
exceeded the associated discounted future net revenues from Hugoton's estimated
proved reserves by approximately $150 million.

Since March 31, 1998, oil and gas prices have declined further. If prices do not
increase from current levels by June 30, 1998, the Company could incur
additional impairment charges, reducing earnings and shareholders' equity.

Oil and Gas Depreciation, Depletion and Amortization. Depreciation, depletion
and amortization of oil and gas properties ("DD&A") for the Current Quarter was
$31.3 million, compared to $24.7 million in the Prior Quarter. This increase was
caused by increased production and an increase in the DD&A rate per mcfe from
$1.20 to $1.36 in the Prior and Current Quarters, respectively. The Company's
DD&A rate is expected to decrease to 



                                       17
<PAGE>   18

approximately $1.10-$1.15 per mcfe for the remainder of 1998 as the result of
the impairment charge, the acquisitions completed in April, and reduced 
drilling in Louisiana.

Depreciation and Amortization of Other Assets. Depreciation and amortization of
other assets ("D&A") increased to $1.4 million in the Current Quarter compared
to $0.9 million in the Prior Quarter. This increase in D&A was caused by
increased investments in depreciable buildings and equipment and increased
amortization of debt issuance costs as a result of the issuance of Senior Notes
in March 1997. The Company anticipates an increase in D&A throughout 1998 as a
result of higher building depreciation expense on the Company's corporate
offices, additional equipment and depreciable assets added from the
acquisitions, and higher amortization caused by the increased offering costs
incurred in the Senior Notes issued in April 1998.

General and Administrative. General and administrative expenses ("G&A"), which
are net of capitalized internal payroll and non-payroll expenses, were $4.4
million in the Current Quarter compared to $2.5 million in the Prior Quarter.
This increase was primarily caused by increased employment levels associated
with the Company's continuing growth. The increase was also caused by increased
accounting, legal, reservoir engineering and other expenses incurred in the
Current Quarter as a result of the Company's change to a December 31 fiscal year
end reporting period for which there were no comparable expenses in the Prior
Quarter. The Company capitalized $2.1 million of internal costs in the Current
Quarter directly related to the Company's oil and gas exploration and
development efforts, compared to $1.4 million in the Prior Quarter. The Company
anticipates that G&A costs for 1998 will continue to increase as the result of
industry wage inflation, legal fees associated with litigation, and increases in
employment due to the acquisition program.

Interest and Other. Interest and other expense increased to $10.7 million in the
Current Quarter from $3.7 million in the Prior Quarter. This increase was a
result of a full quarter of interest expense in the Current Quarter on the $300
million principal amount of Senior Notes issued at the end of the Prior Quarter.
In addition to the interest expense reported, the Company capitalized $2.3
million of interest during the Current Quarter compared to $2.7 million
capitalized in the Prior Quarter. Interest expense will increase during the 
remainder of 1998 as a result of the issuance of $500 million of Senior Notes in
April 1998.

Provision for Income Taxes. The Company recorded no income tax expense for the
Current Quarter, compared to income tax expense of $9.3 million in the Prior
Quarter. At March 31, 1998, the Company had a net operating loss carryforward of
approximately $383 million for regular federal income taxes which will expire in
future years beginning in 2007. Management believes that it cannot be
demonstrated at this time that it is more likely than not that the deferred
income tax assets, comprised primarily of the net operating loss carryforward,
will be realizable in future years, and therefore a valuation allowance of $174
million has been recorded. The Company does not expect to record any book income
tax expense for the remainder of 1998 based on information available at this
time.

RISK MANAGEMENT ACTIVITIES

Periodically the Company utilizes hedging strategies to hedge the price of a
portion of its future oil and gas production. These strategies include (1) swap
arrangements that establish an index-related price above which the Company pays
the counterparty and below which the Company is paid by the counterparty, (2)
the purchase of index-related puts that provide for a "floor" price below which
the counterparty pays the Company the amount by which the price of the commodity
is below the contracted floor, (3) the sale of index-related calls that provide
for a "ceiling" price above which the Company pays the counterparty the amount
by which the price of the commodity is above the contracted ceiling, and (4)
basis protection swaps, which are arrangements that guarantee the price
differential of oil or gas from a specified delivery point or points. Results
from hedging transactions are reflected in oil and gas sales to the extent
related to the Company's oil and gas production. The Company only enters into
hedging transactions related to the Company's oil and gas production volumes or
physical purchase or sale commitments of its oil and gas marketing subsidiaries.

The Company has closed a transaction for natural gas previously hedged for the
period April through November 1999 and received proceeds of $0.9 million, which
will be recognized as income during the corresponding months of production.

The Company does not currently have any oil hedge transactions in place.

Gains or losses on the crude oil and natural gas hedging transactions are
recognized as price adjustments in the months of related production.

LIQUIDITY AND CAPITAL RESOURCES

In April 1998, the Company completed an offering of $230 million of 7%
Cumulative Convertible Preferred Stock and $500 million principal amount of
9.625% Senior Notes due 2005. The net proceeds of these offerings were
approximately $712 million, of which $170 million was used to retire all of the
Company's commercial bank debt, approximately $100 million was used to retire
all $90 million principal amount of the Company's 10.5% Senior Notes due 2002,
$345 million was used to fund certain of the Company's acquisitions, with the
balance of the net proceeds increasing the Company's working capital.

As of March 31, 1998, the Company had a working capital deficit of approximately
$69 million which has been eliminated with the proceeds from the April 1998
Preferred Stock and Senior Note offerings. The Company estimates that its
capital expenditures (excluding acquisitions) for 1998 will be between $225
million and $250 million, including $200-$220 million for drilling and
completion expenditures, and the balance for acreage acquisition and
maintenance, seismic programs and capitalized general and administrative costs.
The capital expenditure budget is largely discretionary, and can be adjusted by
the Company based on operating results or other factors. The Company believes it
has sufficient capital resources from anticipated cash flow from operations and
working capital to fund its drilling program for 1998.

The Company is currently negotiating with its commercial bank group to obtain a
secured revolving bank loan. It is anticipated that this facility will be
completed by the end of May 1998 and will contain terms and conditions similar
to the bank facilities the Company has had in the past. It is anticipated that
the facility will be documented at $500 million, but will have collateral-based
borrowing limitations. The debt incurrence covenants of the Senior Note
indentures will also be a limiting factor. The primary purpose of the facility
will be to fund potential acquisitions of oil and gas reserves.

During April 1998, the Company received a senior debt credit rating decrease
from both Moody's Investors Service and Standard & Poor's Rating Services to B1
and B+, respectively. The rating agencies cited, among other factors, the
Company's long-term debt to total book capitalization, which, after the recent
Senior Notes and Preferred Stock offerings, is approximately 67%.

The Company's cash provided by operating activities increased 24% to $49.2
million during the Current Quarter compared to $39.7 million during the Prior
Quarter. The increase was due primarily to cash provided from changes in current
assets and current liabilities between periods.

<PAGE>   20


Cash used in investing activities increased to $166.5 million during the Current
Quarter from $160.1 million in the Prior Quarter. The Company completed several
acquisitions requiring cash in the Current Quarter which totaled $82 million,
compared to none in the Prior Quarter, offset by a significant decrease in
drilling activity and leasehold acquisitions in the Current Quarter compared to
the Prior Quarter. During the Current Quarter the Company expended approximately
$62 million to initiate drilling on 52 gross (32.9 net) wells and invested
approximately $5 million in leasehold acquisitions. This compares to $129
million to initiate drilling on 35 gross (17.1 net) wells and $30 million to
purchase leasehold in the Prior Quarter.

Cash provided by financing activities was $25.4 million in the Current Quarter,
compared to $280.5 million in the Prior Quarter. During the Current Quarter, the
Company retired $120 million in bank debt which it assumed at the completion of
the Hugoton acquisition. The Company refinanced the Hugoton debt and obtained
additional working capital of $25 million with proceeds from the Company's
commercial bank credit facility. During the Prior Quarter, the Company issued
$300 million in Senior Notes.

The Company is subject to certain routine legal proceedings, none of which are
expected to have a material adverse effect upon the Company's financial
condition or operations. The Company is also a defendant in other non-routine
lawsuits, which are described in Note 3 of the notes to the accompanying
financial statements. Also see Part II, Item 1 of this report. An adverse
outcome in one or more of such suits could have a material effect on the
Company, although management is unable to quantify the Company's exposure to
liability. No provision for litigation liability has been recorded in the
Company's financial statements.

                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is subject to ordinary routine litigation incidental to its
business. In addition, the Company and its officers and directors are defendants
in certain purported class actions based on federal securities fraud claims.
Also the Company is defending claims of patent infringement, tortious
interference with confidentiality contracts and misappropriation of proprietary
information in another pending action. These matters are described in Item 3 of
the Company's Transition Report on Form 10-K for the six-month period ended
December 31, 1997. Subsequent developments are as follows:

On March 16, 1998, the Company and named officers and directors filed a motion
to dismiss in In re Chesapeake Energy Corporation Securities Litigation pending
in the U.S. District Court for the Western District of Oklahoma.

In May 1998, two purported class actions filed on behalf of investors who
purchased common stock of Bayard Drilling Technologies, Inc. in its initial
public offering on November 4, 1997 were dismissed without prejudice pursuant to
stipulation of all parties. These actions had been filed in the District Court
for Oklahoma County, Oklahoma alleging violations by the Company and others of
Sections 11 and 12 of the Securities Act of 1933 and Section 408 of the
Oklahoma Securities Act. The Company was a selling stockholder in the offering.
On May 12, 1998, the plaintiffs in the dismissed cases became co-lead plaintiffs
in the remaining federal case: Tom Yuan v. Bayard, et al. filed in the U.S.
District Court for the Western District of Oklahoma.

ITEM 2. CHANGES IN SECURITIES

On April 22, 1998, the Company sold 4,600,000 shares (the "Shares") of 7%
Cumulative Convertible Preferred Stock having a liquidation preference of $50
per share in a private placement to Donaldson, Lufkin & Jenrette Securities
Corporation, Morgan Stanley & Co. Incorporated, Bear, Stearns & Co. Inc., Lehman
Brothers Inc. and J.P. Morgan Securities Inc. (the "Initial Purchasers")
pursuant to the exemption from registration provided by Section 4 (2) of the
Securities Act of 1933 (the "Securities Act"). The Initial Purchasers resold the
shares to qualified institutional buyers, as defined in, and in reliance on the
exemption from registration provided by, Rule 144A under the Securities Act. The
aggregate offering price for the Shares was $230 million, and aggregate
discounts and commissions were $6.9 million.

Each of the Shares is convertible at the holders' option, exercisable at any
time unless previously redeemed, into shares of Company common stock at a
conversion price of $6.95 per Share (equivalent to a conversion rate of
approximately 7.1942 shares of common stock for each Share), subject to
adjustment pursuant to antidilution provisions.

The Shares are redeemable, in whole or in part, at the Company's option at any
time on or after May 1, 2001, initially at a price of $52.45 per share and
thereafter at prices declining to $50 per share on or after May 1, 2008, plus in
each case all accrued and unpaid dividends to the redemption date, which
redemption price may be paid in cash, by delivery of shares of Company common
stock or through a combination thereof. Upon any Change of Control (as defined
in the Certificate of Designation for the Shares), each holder of Shares will,
in the event that the Market Value (as defined) at such time is less than the
Conversion Price, have a one-time option to convert such holder's Shares into
common stock at an adjusted Conversion Price equal to the greater of (x) the
Market Value for the period ending on the Change of Control date and (y)
66 2/3% of the Market Value for the period ended April 16, 1998. In lieu of
issuing shares of common stock for Shares surrendered for conversion upon a
Change of Control, the Company may, at its option, make a cash payment equal to
the Market Value of the common stock otherwise issuable determined for the
period ending on the Change of Control date.

         3.      Dividends.

                 3.1      The holders of shares of the outstanding Preferred
Stock shall be entitled, when, as and if declared by the Board of Directors out
of funds legally available therefor, to receive cumulative annual cash
dividends of $3.50 per share, payable quarterly in arrears (the "Dividend
Rate").  Dividends payable for each full dividend period will be computed by
dividing the Dividend Rate by four and shall be payable in arrears on each
Dividend Payment Date for the quarterly period ending immediately prior to such
Dividend Payment Date, to the holders of record of Preferred Stock at the close
of business on the Dividend Record Date applicable to such Dividend Payment
Date.   Such dividends shall be cumulative from the Issue Date and shall accrue
on a day-to-day basis, whether or not earned or declared, from and after the
Issue Date.  Dividends on the Preferred Stock which are not declared and paid
when due will compound quarterly on each Dividend Payment Date at the Dividend
Rate.  Dividends payable for any partial dividend period shall be computed on
the basis of actual days elapsed over a 360-day year consisting of twelve
30-day months.  Notwithstanding anything herein to the contrary, the initial





                                      -4-
<PAGE>   5
Dividend Payment Date, which shall be for dividends accrued during the period
commencing on the Issue Date and ending on July 31, 1998, will be August 1,
1998.

                 3.2      Except to the extent specified herein, dividends paid
on the Preferred Stock shall be payable in cash.

                 3.3      No dividends or other distributions (other than a
dividend or distribution payable solely in stock of the Company ranking junior
to the Preferred Stock as to dividends and upon liquidation, including the
Common Stock, and other than cash paid in lieu of fractional shares) may be
declared, made or paid or set apart for payment on the Common Stock or upon any
other stock of the Company ranking junior to or pari passu with the Preferred
Stock as to dividends, and no Common Stock or any other stock of the Company
ranking junior to or pari passu with the Preferred Stock as to dividends or
upon liquidation, including the Preferred Stock, may be repurchased, exchanged,
redeemed or otherwise acquired for any consideration (or any money paid to or
made available for a sinking fund for the redemption of any shares of any such
stock) by the Company (except by conversion into or exchange for stock of the
Company ranking junior to the Preferred Stock as to dividends and upon
liquidation), nor may funds be set apart for payment with respect thereto,
unless full Accumulated Dividends shall have been or contemporaneously are paid
or declared and a sum sufficient for the payment thereof is set apart for such
payment on the Preferred Stock for all Dividend Payment Periods terminating on
or prior to the date of such declaration, payment, redemption, purchase or
acquisition.   Notwithstanding the foregoing, if full dividends have not been
paid on the Preferred Stock or on any other preferred stock ranking pari passu
with the Preferred Stock as to dividends, dividends may be declared and paid on
the Preferred Stock and such other preferred stock so long as the dividends are
declared and paid pro rata so that the amounts of dividends declared per share
on the Preferred Stock and such other preferred stock will in all cases bear to
each other the same ratio that Accrued Dividends on the shares of Preferred
Stock and such other preferred stock bear to each other; provided, that if such
dividends are paid in cash on the other preferred stock, dividends will also be
paid in cash on the Preferred Stock.

                 3.4      Holders of shares of Preferred Stock shall not be
entitled to any dividends on the Preferred Stock, whether payable in cash,
property or stock, in excess of full cumulative dividends at the Dividend Rate
provided herein.  No interest, or sum of money in lieu of interest, shall be
payable in respect of any dividend payment or payments on the Preferred Stock
which may be in arrears (it being understood that the compounding of unpaid
dividends shall not constitute interest or money in lieu of interest).

                 3.5      The holders of shares of Preferred Stock at the close
of business on a Dividend Record Date will be entitled to receive the dividend
payment on those shares (except that holders of shares called for redemption on
a redemption date between the Dividend Record Date and the Dividend Payment
Date will be entitled to receive such dividend on such redemption date as
indicated in Section 3.1 hereof) on the corresponding Dividend Payment Date
notwithstanding the subsequent conversion thereof or the Company's default in
payment of the dividend due on that Dividend Payment Date.  However, shares of
Preferred Stock surrendered





                                      -5-
<PAGE>   6
for conversion during the period between the close of business on any Dividend
Record Date and the close of business on the day immediately preceding the
applicable Dividend Payment Date (except for shares called for redemption on a
redemption date during that period) must be accompanied by payment of an amount
equal to the dividend payable on the shares on that Dividend Payment Date.  A
holder of shares of Preferred Stock on a Dividend Record Date who (or whose
transferee) tenders any shares for conversion on or before a Dividend Payment
Date will receive the dividend payable by the Company on the Preferred Stock on
that date, and the converting holder need not include payment in the amount of
such dividend upon surrender of shares of Preferred Stock for conversion.
Except as provided above and in Section 9(b) hereof, the Company shall make no
payment or allowance for unpaid dividends, whether or not in arrears, on
converted shares or for dividends on the shares of Common Stock issued upon
conversion.

         4.      Optional Redemption.

                 4.1      The Preferred Stock may not be redeemed prior to May
1, 2001.  At any time on or after May 1, 2001, the Company may, at its sole
option, subject to Section 3.3, redeem, out of funds legally available
therefor, all or any part of the outstanding shares of Preferred Stock, in
cash, by delivery of fully paid and nonassessable shares of Common Stock or by
a combination thereof, upon not less than 30 days' nor more than 60 days'
notice provided in the manner specified in Section 5 hereof, during the
12-month periods commencing on May 1 of the years set forth below for the
amount per share of Preferred Stock set forth opposite such years, plus
Accumulated Dividends and Accrued Dividends thereon to the redemption date:

</TABLE>

                 4.2      If the Company elects to make redemption payments in
Common Stock, the number of shares of Common Stock to be delivered in exchange
for each share of Preferred Stock will be calculated by dividing the applicable
redemption price per share of Preferred Stock by the Market Value for the
period ending on the third Business Day immediately preceding the date the
notice of redemption is given.  To the extent that the amount of the redemption
payment payable to a holder of Preferred Stock (in respect of all shares held
by such holder) does not equal a whole number of shares of Common Stock, such
fractional amount shall be paid in cash to such holder of Preferred Stock based
on the same Market Value.  If any dividends on the





                                      -6-
<PAGE>   7
Preferred Stock are in arrears, no shares of Preferred Stock shall be redeemed
unless all outstanding shares of Preferred Stock are simultaneously redeemed.

         5.      Procedure for Redemption.

                 5.1      In the event the Company shall elect to redeem shares
of Preferred Stock pursuant to Section 4 hereof, notice of such redemption
shall be given (i) by publication in a newspaper of general circulation in the
Borough of Manhattan, City and State of New York (if such publication shall be
required by applicable law, rule, regulation or securities exchange
requirement) or (ii) by first-class mail to each record holder of the shares to
be redeemed, at such holder's address as the same appears on the books of the
Company, in either case not less than 30 nor more than 60 days prior to the
redemption date.  Each such notice shall state (i) the time and date as of
which the redemption shall occur; (ii) the total number of shares of Preferred
Stock to be redeemed and, if fewer than all the shares held by such holder are
to be redeemed, the number of such shares to be redeemed from such holder;
(iii) the redemption price (whether to be paid in cash or shares of Common
Stock or a combination thereof); (iv) the place or places where certificates
for such shares are to be surrendered for payment of the redemption price and
delivery of certificates representing shares of Common Stock (if the Company so
chooses); (v) that dividends on the shares to be redeemed will cease to accrue
on such redemption date unless the Company defaults in the payment of the
redemption price; and (vi) the name of any bank or trust company, if any,
performing the duties referred to in Section 5.3 below.

                 5.2      On or before any redemption date, each holder of
shares of Preferred Stock to be redeemed shall surrender the certificate or
certificates representing such shares of Preferred Stock to the Company, in the
manner and at the place designated in the notice of redemption and on the
redemption date, the full redemption price, payable in cash, fully paid and
nonassessable shares of Common Stock or a combination thereof, for such shares
of Preferred Stock shall be paid or delivered to the person whose name appears
on such certificate or certificates as the owner thereof, and the shares
represented by each surrendered certificate shall be returned to authorized but
unissued shares of preferred stock of any or no series.  Upon surrender (in
accordance with the notice of redemption) of the certificate or certificates
representing any shares to be so redeemed (properly endorsed or assigned for
transfer, if the Company shall so require and the notice of redemption shall so
state), such shares shall be redeemed by the Company at the redemption price.
If fewer than all the shares represented by any such certificate are to be
redeemed, a new certificate shall be issued representing the unredeemed shares,
without costs to the holder thereof, together with the amount of cash, if any,
in lieu of fractional shares.

                 5.3      If a notice of redemption shall have been given as
provided in Section 5.1, dividends on the shares of Preferred Stock so called
for redemption shall cease to accrue, such shares shall no longer be deemed to
be outstanding, and all rights of the holders thereof as stockholders of the
Company with respect to shares so called of redemption (except for the right to
receive from the Company the redemption price) shall cease (including any right
to receive dividends otherwise payable on any Dividend Payment Date that would
have occurred after the time and date of redemption) either (i) from and after
the time and date fixed in the notice of





                                      -7-
<PAGE>   8
redemption as the time and date of redemption (unless the Company shall default
in the payment of the redemption price, in which case such rights shall not
terminate at such time and date) or (ii) if the Company shall so elect and
state in the notice of redemption, from and after the time and date (which date
shall be the date fixed for redemption or an earlier date not less than 30 days
after the date of mailing of the redemption notice) on which the Company shall
irrevocably deposit in trust for the holders of the shares to be redeemed with
a designated bank or trust for the holders of the shares of Preferred Stock to
be redeemed with a designated bank or trust company doing business in the
Borough of Manhattan, City and State of New York, as paying agent, money or
such number of fully paid and nonassessable shares of Common Stock (or a
combination thereof)  sufficient to pay at the office of such paying agent, on
the redemption date, the redemption price.  Any money or shares of Common Stock
so deposited with any such paying agent which shall not be required for such
redemption shall be returned to the Company forthwith.  Subject to applicable
escheat laws, any moneys so set aside by the Company and unclaimed at the end
of one year from the redemption date shall revert to the general funds of the
Company, after which reversion the holders of such shares so called for
redemption shall look only to the general funds of the Company for the payment
of the redemption price without interest.  Any interest accrued on funds so
deposited shall be paid to the Company from time to time.

                 5.4      In the event that fewer than all the outstanding
shares of Preferred Stock are to be redeemed, the shares to be redeemed shall
be determined pro rata or by lot, as determined by the Company, except that the
Company may redeem such shares held by any holder of fewer than 100 shares (or
shares held by holders who would hold fewer than 100 shares as a result of such
redemption), as may be determined by the Company.

         6.      Change of Control.

                 6.1      Upon the occurrence of a Change of Control of the
Company, each holder of Preferred Stock shall, in the event that the Market
Value for the period ending on the Change of Control Date is less than the
Conversion Price, have a one-time option (the "Change of Control Option") to
convert all of such holder's shares of Preferred Stock into fully paid and
nonassessable shares of Common Stock at a conversion price equal to the greater
of (i) the Market Value for the period ending on the Change of Control Date and
(ii) 66 2/3 % of the Market Value for the period ended April 16, 1998.  The
Change of Control Option must be exercised during the period of not less than
30 days nor more than 60 days (the actual number of days to be as specified in
the notice furnished in accordance with Section 6.2) commencing on the third
Business Day after notice of a Change in Control has been given by the Company
in accordance with Section 6.2.  In lieu of issuing the shares of Common Stock
issuable upon conversion in the event of a Change of Control, the Company may,
at its sole option, make a cash payment equal to the Market Value determined
for the period ending on the Change of Control Date of the shares Common Stock
otherwise issuable.

                 6.2      In the event of a Change of Control, notice of such
Change of Control shall be given, within five Business Days of the Change of
Control Date, by the Company by first-





                                      -8-
<PAGE>   9
class mail to each record holder of shares of Preferred Stock, at such holder's
address as the same appears on the books of the Company.  Each such notice
shall state (i) that a Change of Control has occurred; (ii) the last day on
which the Change of Control Option may be exercised (the "Expiration Date");
(iii) the name and address of the paying agent; and (iv) the procedures that
holders must follow to exercise the Change of Control Option.

                 6.3      On or before the Expiration Date, each holder of
shares of Preferred Stock wishing to exercise the Change of Control Option
shall surrender the certificate or certificates representing the shares of
Preferred Stock to be converted, in the manner and at the place designated in
the notice described in Section 6.2, and on such date the cash or shares of
Common Stock due to such holder shall be delivered to the person whose name
appears on such certificate or certificates as the owner thereof and each
surrendered certificate shall be returned to authorized but unissued shares.
Upon surrender (in accordance with the notice described in Section 6.2 of the
certificate or certificates representing any shares to be so converted
(properly endorsed or assigned for transfer, if the Company shall so require
and the notice shall so state), such shares shall be converted by the Company
at the Conversion Price.

                 6.4      The rights of holders of Preferred Stock pursuant to
this Section 6 are in addition to, and not in lieu of, the rights of holders of
Preferred Stock provided for in Section 9 hereof.

         7.      Voting.

                 7.1      The shares of Preferred Stock shall have no voting
rights except as required by law or as set forth below:

                 (a)      If and whenever at any time or times a Voting Rights
Triggering Event occurs, then the number of directors constituting the Board of
Directors shall be increased by two and the holders of shares of Preferred
Stock, voting separately as a class with any other preferred stock or
preference security having similar voting rights (the "Voting Rights Class"),
will be entitled at the next regular or special meeting of stockholders of the
Company to elect two directors of the Company to fill the newly created
directorships.

                 (b)      Such voting rights may be exercised at a special
meeting of the holders of the shares of the Voting Rights Class, called as
hereinafter provided, or at any annual meeting of stockholders held for the
purpose of electing directors, and thereafter at each such annual meeting until
such time as all dividends in arrears on the shares of Preferred Stock shall
have been paid in full, at which time or times such voting rights and the term
of the directors elected pursuant to Section 7.1(a) shall terminate.

                 (c)      At any time when such voting rights shall have vested
in holders of shares of the Voting Rights Class, a proper officer of the
Company may call, and, upon written request of the record holders of shares
representing twenty-five percent (25%) of the voting power of the shares then
outstanding of the Voting Rights Class, addressed to the Secretary of the
Company,





                                      -9-
<PAGE>   10
shall call a special meeting of the holders of shares of the Voting Rights
Class.  Such meeting shall be held at the earliest practicable date upon the
notice required for annual meetings of stockholders at the place for holding
annual meetings of stockholders of the Company, or, if none, at a place
designated by the Board of Directors.  Notwithstanding the provisions of this
Section 7.1(c), no such special meeting shall be called during a period within
the 60 days immediately preceding the date fixed for the next annual meeting of
stockholders in which such case, the election of directors pursuant to Section
7.1(a) shall be held at such annual meeting of stockholders.

                 (d)      At any meeting held for the purpose of electing
directors at which the holders of the Voting Rights Class shall have the right
to elect directors as provided herein, the presence in person or by proxy of
the holders of shares representing more than fifty percent (50%) in voting
power of the then outstanding shares of the Voting Rights Class shall be
required and shall be sufficient to constitute a quorum of such class for the
election of directors by such class.  The affirmative vote of the holders of
shares of Preferred Stock constituting a majority of the shares of Preferred
Stock present at such meeting, in person or by proxy, shall be sufficient to
elect such director.

                 (e)      Any director elected pursuant to the voting rights
created under this Section 7.1 shall hold office until the next annual meeting
of stockholders (unless such term has previously terminated pursuant to Section
7.1(b)) and any vacancy in respect of any such director shall be filled only by
vote of the remaining director so elected by holders of the Voting Rights
Class, or if there be no such remaining director, by the holders of shares of
the Voting Rights Class at a special meeting called in accordance with the
procedures set forth in this Section 7, or, if no such special meeting is
called, at the next annual meeting of stockholders.  Upon any termination of
such voting rights, the term of office of all directors elected pursuant to
this Section 7 shall terminate.

                 (f)      So long as any shares of Preferred Stock remain
outstanding, unless a greater percentage shall then be required by law, the
Company shall not, without the affirmative vote or consent of the holders of at
least 66 2/3% of the outstanding Preferred Stock voting or consenting, as the
case may be, separately as one class, (i) create, authorize or issue any class
or series of stock (or security convertible into stock) of the Company ranking
pari passu or senior to the Preferred Stock as to dividends, liquidation rights
or voting rights or (ii) amend the Certificate of Incorporation so as to affect
adversely the specified rights, preferences, privileges or voting rights of
holders of shares of Preferred Stock, including (x) increasing the authorized
number of shares of preferred stock and (y) issuing after the Issue Date any
shares of Preferred Stock in excess of such additional shares of Preferred
Stock as may be issued upon the exercise of the over-allotment option pursuant
to the Purchase Agreement.  The holders of at least a majority of the
outstanding shares of Preferred Stock, voting separately as one class, may
waive compliance with any provision of this Certificate of Designation.

                 (g)      In exercising the voting rights set forth in this
Section 7.1, each share of Preferred Stock shall be entitled to one vote.

                 7.2      Except as set forth in Section 7.1, the Company may
create, authorize or issue any shares of Junior Stock or increase or decrease
the amount of authorized capital stock of any class other than the preferred
stock, without the consent of the holders of Preferred Stock constituting the
Voting Rights Class, and in taking such actions the Company shall not be deemed
to have affected adversely the rights, preferences, privileges or voting rights
of holders of shares of Preferred Stock.

         8.      Liquidation Rights.

                 8.1      In the event of any liquidation, dissolution or
winding-up of the Company, whether voluntary of involuntary, the holders of the
shares of Preferred Stock shall be entitled to receive out of the assets of the
Company available for distribution to stockholders up to the Liquidation
Preference plus Accumulated Dividends and Accrued Dividends thereon in
preference to the holders of, and before any distribution is made on, any other
class or series of stock of the Company ranking junior to the Preferred Stock
upon liquidation, including, without limitation, on any Common Stock.

                 8.2      Neither the sale, conveyance, exchange or transfer
(for cash, shares of stock, securities or other consideration) of all or
substantially all the property and assets of the Company nor the merger or
consolidation of the Company into or with any other corporation, or the merger
or consolidation of any other corporation into or with the Company, shall be
deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, for the purposes of this Section 8.

                 8.3      After the payment to the holders of the shares of
Preferred Stock of full preferential amounts provided for in this Section 8,
the holders of Preferred Stock as such shall have no right or claim to any of
the remaining assets of the Company.

                 8.4      In the event the assets of the Company available for
distribution to the holders of shares of Preferred Stock upon any liquidation,
dissolution or winding up of the Company, whether voluntary or involuntary,
shall be insufficient to pay in full all amounts to which such holders are
entitled pursuant to Section 8.1, no such distribution shall be made on account
of any shares of any other stock of the Company ranking pari passu with the
Preferred Stock  upon such liquidation, dissolution or winding up unless
proportionate distributable amounts shall be paid on account of the shares of
Preferred Stock, ratably, in proportion to the full distributable amounts for
which holders of all Preferred Stock and of any other stock of the Company
ranking pari passu with the Preferred Stock are entitled upon such liquidation,
dissolution or winding up.

         9.      Conversion.

                 (a)      Each holder of Preferred Stock shall have the right,
at its option, exercisable at any time and from time to time from the Issue
Date to convert, subject to the terms and provisions of this Section 9, any or
all of such holder's shares of Preferred Stock.  In such





                                      -11-
<PAGE>   12
case, the shares of Preferred Stock shall be converted into such whole number
of fully paid and nonassessable shares of Common Stock as is equal, subject to
Section 9(g), to the product of the number of shares of Preferred Stock being
so converted multiplied by the quotient of (i) the Liquidation Preference plus
any Accumulated Dividends and any Accrued Dividends to and including the date
of conversion divided by (ii) the Conversion Price (as defined below) then in
effect, except that with respect to any share which shall be called for
redemption such conversion right shall terminate at the close of business on
the date of redemption of such share, unless the Company shall default in
performance or payment due upon exchange or redemption thereof.  The Conversion
Price shall be $6.95, subject to adjustment as set forth in Section 9(c).

         The conversion right of a holder of Preferred Stock shall be exercised
by the holder by the surrender to the Company of the certificates representing
shares to be converted at any time during usual business hours at its principal
place of business or the offices of its duly appointed Transfer Agent (as
defined in Section 10) to be maintained by it, accompanied by written notice
that the holder elects to convert all or a portion of the shares of Preferred
Stock represented by such certificate and specifying the name or names (with
address) in which a certificate or certificates for shares of Common Stock are
to be issued and (if so required by the Company or its duly appointed Transfer
Agent) by a written instrument or instruments of transfer in form reasonably
satisfactory to the Company or its duly appointed Transfer Agent duly executed
by the holder or its duly authorized legal representative and transfer tax
stamps or funds therefor, if required pursuant to Section 9(i).  Immediately
prior to the close of business on the date of receipt by the Company or its
duly appointed Transfer Agent of notice of conversion of shares of Preferred
Stock, each converting holder of Preferred Stock shall be deemed to be the
holder of record of Common Stock issuable upon conversion of such holder's
Preferred Stock notwithstanding that the share register of the Company shall
then be closed or that certificates representing such Common Stock shall not
then be actually delivered to such person.  Upon notice from the Company, each
holder of Preferred Stock so converted shall promptly surrender to the Company,
at any place where the Company shall maintain a Transfer Agent, certificates
representing the shares so converted, duly endorsed in blank or accompanied by
proper instruments of transfer.  On the date of any conversion, all rights with
respect to the shares of Preferred Stock so converted, including the rights, if
any, to receive notices, will terminate, except only the rights of holders
thereof to (i) receive certificates for the number of shares of Common Stock
into which such shares of Preferred Stock have been converted; (ii) the payment
of any Accumulated Dividends or Accrued Dividends thereon; and (iii) exercise
the rights to which they are entitled as holders of Common Stock.

                 If the last day for the exercise of the conversion right shall
not be a Business Day, then such conversion right may be exercised on the next
preceding Business Day.

                 (b)      When shares of Preferred Stock are converted pursuant
to this Section 9, all Accumulated Dividends and all Accrued Dividends (whether
or not declared or currently payable) on the Preferred Stock so converted to
(and not including) the date of conversion less any amounts payable by the
Company in cash pursuant to Section 3.5.  hereof shall be immediately due and
payable, at the Company's option, (i) in cash; (ii) in a number of fully paid





                                      -12-
<PAGE>   13
and nonassessable shares of Common Stock equal to the quotient of (A) the
amount of Accumulated Dividends and Accrued Dividends payable to the holders of
Preferred Stock hereunder, divided by (B) the Market Value for the period
ending on the date of conversion; or (iii) a combination thereof.

                 (c)      The Conversion Price shall be subject to adjustment
as follows:

                          (i)     In case the Company shall at any time or from
time to time (A) make a redemption payment or pay a dividend (or other
distribution) payable in shares of Common Stock on any class of capital stock
(which, for purposes of this Section 9(c) shall include, without limitation,
any dividends or distributions in the form of options, warrants or other rights
to acquire capital stock) of the Company (other than the issuance of shares of
Common Stock in connection with the payment in redemption for, of dividends on
or the conversion of Preferred Stock); (B) subdivide the outstanding shares of
Common Stock into a larger number of shares; (C) combine the outstanding shares
of Common Stock into a smaller number of shares; (D) issue any shares of its
capital stock in a reclassification of the Common Stock; or (E) pay a dividend
or make a distribution to all holders of shares of Common Stock (other than a
dividend or distribution paid or made to holders of shares of Preferred Stock
in the manner provided in Section 9(b) or a dividend or distribution subject to
Section 9(c)(ii)) pursuant to a stockholder rights plan, "poison pill" or
similar arrangement then, and in each such case, the Conversion Price in effect
immediately prior to such event shall be adjusted (and any other appropriate
actions shall be taken by the Company) so that the holder of any share of
Preferred Stock thereafter surrendered for conversion shall be entitled to
receive the number of shares of Common Stock that such holder would have owned
or would have been entitled to receive upon or by reason of any of the events
described above, had such share of Preferred Stock been converted into shares
of Common Stock immediately prior to the occurrence of such event.  An
adjustment made pursuant to this Section 9(c)(i) shall become effective
retroactively (x) in the case of any such dividend or distribution, to the day
immediately following the close of business on the record date for the
determination of holders of Common Stock entitled to receive such dividend or
distribution or (y) in the case of any such subdivision, combination or
reclassification, to the close of business on the day upon which such corporate
action becomes effective.

                          (ii)    In case the Company shall at any time or from
time to time issue to all holders of its Common Stock rights, options or
warrants entitling the holders thereof to subscribe for or purchase shares of
Common Stock (or securities convertible into or exchangeable for shares of
Common Stock) at a price per share less than the Market Value for the period
ending on the date of issuance (treating the price per share of any security
convertible or exchangeable or exercisable into Common Stock as equal to (A)
the sum of the price paid to acquire such security convertible, exchangeable or
exercisable into Common Stock plus any additional consideration payable
(without regard to any anti-dilution adjustments) upon the conversion, exchange
or exercise of such security into Common Stock divided by (B) the number of
shares of Common Stock into which such convertible, exchangeable or exercisable
security is initially convertible, exchangeable or exercisable), other than (I)
issuances of such rights, options or warrants if the holder of Preferred Stock
would be entitled to receive such rights, options or





                                      -13-
<PAGE>   14
warrants upon conversion at any time of shares of Preferred Stock and (II)
issuances that are subject to certain triggering events (until such time as
such triggering events occur), then, and in each such case, the Conversion
Price then in effect shall be adjusted by dividing the Conversion Price in
effect on the day immediately prior to the record date of such issuance by a
fraction (y) the numerator of which shall be the sum of the number of shares of
Common Stock outstanding on such record date plus the number of additional
shares of Common Stock issued or to be issued upon or as a result of the
issuance of such rights, options or warrants (or the maximum number into or for
which such convertible or exchangeable securities initially may convert or
exchange or for which such options, warrants or other rights initially may be
exercised) and (z) the denominator of which shall be the sum of the number of
shares of Common Stock outstanding on such record date plus the number of
shares of Common Stock which the aggregate consideration for the total number
of such additional shares of Common Stock so issued (or into or for which such
convertible or exchangeable securities may convert or exchange or for which
such options, warrants or other rights may be exercised plus the aggregate
amount of any additional consideration initially payable upon the conversion,
exchange or exercise of such security) would purchase at the Market Value for
the period ending on the date of conversion; provided, that if the Company
distributes rights or warrants (other than those referred to above in this
subparagraph (c)(ii))  pro rata to the holders of Common Stock, so long as
such rights or warrants have not expired or been redeemed by the Company, (y)
the holder of any Preferred Stock surrendered for conversion shall be entitled
to receive upon such conversion, in addition to the shares of Common Stock then
issuable upon such conversion (the "Conversion Shares"), a number of rights or
warrants to be determined as follows: (i) if such conversion occurs on or prior
to the date for the distribution to the holders of rights or warrants of
separate certificates evidencing such rights or warrants (the "Distribution
Date"), the same number of rights or warrants to which a holder of a number of
shares of Common Stock equal to the number of Conversion Shares is entitled at
the time of such conversion in accordance with the terms and provisions
applicable to the rights or warrants and (ii) if such conversion occurs after
the Distribution Date, the same number of rights or warrants to which a holder
of the number of shares of Common Stock into which such Preferred Stock was
convertible immediately prior to such Distribution Date would have been
entitled on such Distribution Date had such Preferred Stock been converted
immediately prior to such Distribution Date in accordance with the terms and
provisions applicable to the rights and warrants, and (z) the Conversion Price
shall not be subject to adjustment on account of any declaration, distribution
or exercise of such rights or warrants.

                          (iii)   In case the Company shall at any time or from
time to time (A) make a pro rata distribution to all holders of shares of its
Common Stock consisting exclusively of cash (excluding any cash portion of
distributions referred to in paragraph (c)(i) above, or cash distributed upon a
merger or consolidation to which paragraph (g) below applies), that, when
combined together with (x) all other such all-cash distributions made within
the then-preceding 12 months in respect of which no adjustment has been made
and (y) any cash and the fair market value of other consideration paid or
payable in respect of any tender offer by the Company or any of its
subsidiaries for shares of Common Stock concluded within the then-preceding 12
months in respect of which no adjustment pursuant to this Section 9(c) has been
made, in the





                                      -14-
<PAGE>   15
aggregate exceeds 15% of the Company's market capitalization (defined as the
product of the Market Value for the period ending on the record date of such
distribution times the number of shares of Common Stock outstanding on such
record date) on the record date of such distribution;  (B) complete a tender or
exchange offer by the Company or any of its subsidiaries for shares of Common
Stock that involves an aggregate consideration that, together with (I) any cash
and other consideration payable in a tender or exchange offer by the Company or
any of its subsidiaries for shares of Common Stock expiring within the
then-preceding 12 months in respect of which no adjustment pursuant to this
Section 9(c) has been made and (II) the aggregate amount of any such all-cash
distributions referred to in clause (A) above to all holders of shares of
Common Stock within the then-preceding 12 months in respect of which no
adjustments have been made, exceeds 15% of the Company's market capitalization
on the expiration of such tender offer; or (C) make a distribution to all
holders of its Common Stock consisting of evidences of indebtedness, shares of
its capital stock other than Common Stock or assets (including securities, but
excluding those dividends, rights, options, warrants and distributions referred
to in paragraphs (c)(i) or (c)(ii) above), then, and in each such case, the
Conversion Price then in effect shall be adjusted by dividing the Conversion
Price in effect immediately prior to the date of such distribution or
completion of such tender or exchange offer, as the case may be,) by a fraction
(x) the numerator of which shall be the Market Value for the period ending on
the record date referred to below, or, if such adjustment is made upon the
completion of a tender or exchange offer, on the payment date for such offer,
and (y) the denominator of which shall be such Market Value less the then fair
market value (as determined by the Board of Directors of the Company) of the
portion of the cash, evidences of indebtedness, securities or other assets so
distributed or paid in such tender or exchange offer, applicable to one share
of Common Stock (but such denominator not to be less than one); provided,
however, that no adjustment shall be made with respect to any distribution of
rights to purchase securities of the Company if the holder of shares of
Preferred Stock would otherwise be entitled to receive such rights upon
conversion at any time of shares of Preferred Stock into shares of Common Stock
unless such rights are subsequently redeemed by the Company, in which case such
redemption shall be treated for purposes of this Section 9(c)(iii) as a
dividend on the Common Stock.  Such adjustment shall be made whenever any such
distribution is made or tender or exchange offer is completed, as the case may
be, and shall become effective retroactively to a date immediately following
the close of business on the record date for the determination of stockholders
entitled to receive such distribution.

                          (iv)    In the case the Company at any time or from
time to time shall take any action affecting its Common Stock (it being
understood that the issuance or sale of shares of Common Stock (or securities
convertible into or exchangeable for shares of Common Stock, or any options,
warrants or other rights to acquire shares of Common Stock) to any Person at a
price per share less than the Conversion Price then in effect shall not be
deemed such an action), other than an action described in any of Section
9(c)(i) through Section 9(c)(iii), inclusive, or Section 9(g), then the
Conversion Price shall be adjusted in such manner and at such time as the Board
of Directors of the Company in good faith determines to be equitable in the
circumstances (such determination to be evidenced in a resolution, a certified
copy of which shall be mailed to the holders of the Preferred Stock).





                                      -15-
<PAGE>   16
                          (v)     Notwithstanding anything herein to the
contrary, no adjustment under this Section 9(c) need be made to the Conversion
Price unless such adjustment would require an increase or decrease of at least
1% of the Conversion Price then in effect.  Any lesser adjustment shall be
carried forward and shall be made at the time of and together with the next
subsequent adjustment, if any, which, together with any adjustment or
adjustments so carried forward, shall amount to an increase or decrease of at
least 1% of such Conversion Price.

                          (vi)    The Company reserves the right to make such
reductions in the Conversion Price in addition to those required in the
foregoing provisions as it considers advisable in order that any event treated
for Federal income tax purposes as a dividend of stock or stock rights will not
be taxable to the recipients.  In the event the Company elects to make such a
reduction in the Conversion Price, the Company will comply with the
requirements of Rule 14e-1 under the Exchange Act, and any other securities
laws and regulations thereunder if and to the extent that such laws and
regulations are applicable in connection with the reduction of the Conversion
Price.

                 (d)      If the Company shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive a dividend or
other distribution, and shall thereafter (and before the dividend or
distribution has been paid or delivered to stockholders) legally abandon its
plan to pay or deliver such dividend or distribution, then thereafter no
adjustment in the Conversion Price then in effect shall be required by reason
of the taking of such record.

                 (e)      Upon any increase or decrease in the Conversion
Price, then, and in each such case, the Company promptly shall deliver to each
registered holder of Preferred Stock a certificate signed by an authorized
officer of the Company, setting forth in reasonable detail the event requiring
the adjustment and the method by which such adjustment was calculated and
specifying the increased or decreased Conversion Price then in effect following
such adjustment.

                 (f)      No fractional shares or scrip representing fractional
shares of Common Stock shall be issued upon the conversion of any shares of
Preferred Stock.  If more than one share of Preferred Stock shall be
surrendered for conversion at one time by the same holder, the number of full
shares of Common Stock issuable upon conversion thereof shall be computed on
the basis of the aggregate Liquidation Preference of the shares of Preferred
Stock so surrendered.  If the conversion of any share or shares of Preferred
Stock results in a fraction, an amount equal to such fraction multiplied by the
last reported sale price of the Common Stock on the NYSE (or on such other
national securities exchange or authorized quotation system on which the Common
Stock is then listed for trading or authorized for quotation or, if the Common
Stock is not then so listed or authorized for quotation, an amount determined
in good faith by the Board of Directors to be the fair value of the Common
Stock) at the close of business on the trading day next preceding the day of
conversion shall be paid to such holder in cash by the Company.

                 (g)      In the event  of any capital reorganization or
reclassification or other change of outstanding shares of Common Stock (other
than a change in par value, or from par value to no par value, or from no par
value to par value), or in the event of any consolidation





                                      -16-
<PAGE>   17
or merger of the Company with or into another Person (other than a
consolidation or merger in which the Company is the resulting or surviving
Person and which does not result in any reclassification or change of
outstanding Common Stock), or in the event of any sale or other disposition to
another Person of all or substantially all of the assets of the Company (other
than any assets not owned directly or indirectly by the Company and its
subsidiaries) (computed on a consolidated basis) (any of the foregoing, a
"Transaction"), each share of Preferred Stock then outstanding shall, without
the consent of any holder of Preferred Stock, become convertible only into the
kind and amount of shares of stock or other securities (of the Company or
another issuer) or property or cash receivable upon such Transaction by a
holder of the number of shares of Common Stock into which such share of
Preferred Stock could have been converted immediately prior to such Transaction
after giving effect to any adjustment event.  The provisions of this Section
9(g) and any equivalent thereof in any such certificate similarly shall apply
to successive Transactions.  The provisions of this Section 9(g) shall be the
sole right of holders of Preferred Stock in connection with any Transaction and
such holders shall have no separate vote thereon.

                 (h)      In the event of any distribution by the Company to
its stockholders of all or substantially all of its assets (other than any
assets not owned directly or indirectly by the Company and its subsidiaries)
(computed on a consolidated basis), each holder of Preferred Stock will
participate pro rata in such distribution based on the number of shares of
Common Stock into which such holders' shares of Preferred Stock would have been
convertible immediately prior to such distribution.

                 (i)      The Company shall at all times reserve and keep
available for issuance upon the conversion of the Preferred Stock such number
of its authorized but unissued shares of Common Stock as will from time to time
be sufficient to permit the conversion of all outstanding shares of Preferred
Stock, and shall take all action required to increase the authorized number of
shares of Common Stock if at any time there shall be insufficient unissued
shares of Common Stock to permit such reservation or to permit the conversion
of all outstanding shares of Preferred Stock.

                 (j)      The issuance or delivery of certificates for Common
Stock upon the conversion of shares of Preferred Stock shall be made without
charge to the converting holder of shares of Preferred Stock for such
certificates or for any tax in respect of the issuance or delivery of such
certificates or the securities represented thereby, and such certificates shall
be issued or delivered in the respective names of, or in such names as may be
directed by, the holders of the shares of Preferred Stock converted; provided,
however, that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificate in a name other than that of the holder of the shares of
Preferred Stock converted, and the Company shall not be required to issue or
deliver such certificate unless or until the Person or Persons requesting the
issuance or delivery thereof shall have paid to the Company the amount of such
tax or shall have established to the reasonable satisfaction of the Company
that such tax has been paid.

<PAGE>   18
         10.     Transfer Agent and Registrar.  The duly appointed transfer
agent and registrar (the "Transfer Agent") for the Preferred Stock shall be UMB
Bank, N.A.  The Company may, in its sole discretion, remove the Transfer Agent
with 10 days' prior written notice to the Transfer Agent; provided, that the
Company shall appoint a successor Transfer Agent who shall accept such
appointment prior to the effectiveness of such removal.

         11.     Transfer Restrictions.  The shares of Preferred Stock have not
be registered under the Securities Act of 1933, as amended (the "Securities
Act"), and, accordingly, may not be offered, sold, pledged or otherwise
transferred except (1) to a Person whom the seller reasonably believes is a
qualified institutional buyer within the meaning of Rule 144A under the
Securities Act purchasing for its own account or for the account of a qualified
institutional buyer in a transaction meeting the requirements of Rule 144A, (2)
in a transaction meeting the requirements of Rule 144 under the Securities Act,
(3) in accordance with another exemption from the registration requirements of
the Securities Act (and based upon opinion of counsel acceptable to the
Company), (4) to the Company or any of its subsidiaries,  or (5) pursuant to an
effective registration statement under the Securities Act, and in each case, in
accordance with all applicable securities laws of any State of the United
States.  The Transfer Agent shall refuse to register the transfer of any shares
of Preferred Stock that violates this Section 11.

         12.     Other Provisions.

                 12.1     With respect to any notice to a holder of shares of
Preferred Stock required to be provided hereunder, neither failure to mail such
notice, nor any defect therein or in the mailing thereof, to any particular
holder shall affect the sufficiency of the notice or the validity of the
proceedings referred to in such notice with respect to the other holders or
affect the legality or validity of any distribution, rights, warrant,
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding-up, or the vote upon any such action.  Any notice which
was mailed in the manner herein provided shall be conclusively presumed to have
been duly given whether or not the holder receives the notice.

                 12.2     Shares of Preferred Stock issued and reacquired will
be retired and canceled promptly after reacquisition thereof and, upon
compliance with the applicable requirements of Oklahoma law, have the status of
authorized but unissued shares of preferred stock of the Company undesignated
as to series and may with any and all other authorized but unissued shares of
preferred stock of the Company be designated or redesignated and issued or
reissued, as the case may be, as part of any series of preferred stock of the
Corporation, except that any issuance or reissuance of shares of Preferred
Stock must be in compliance with this Certificate of Designation.

                 12.3     The shares of Preferred Stock shall be issuable only 
in whole shares.

                 12.4     All notices periods referred to herein shall commence
on the date of the mailing of the applicable notice.

                             MERGING
                  CHESAPEAKE ENERGY CORPORATION
                               INTO
                 CHESAPEAKE OKLAHOMA CORPORATION


          CHESAPEAKE ENERGY CORPORATION, a Delaware corporation
(the "Corporation"),     DOES HEREBY CERTIFY:


          FIRST:  That it owns 100% of the issued and outstanding
shares of the capital stock of CHESAPEAKE OKLAHOMA CORPORATION, an
Oklahoma corporation ("Chesapeake Oklahoma").


          SECOND:  That its board of directors at a meeting held on
the 15th day of October, 1996, determined to merge the Corporation
into CHESAPEAKE OKLAHOMA CORPORATION, and did adopt the following
resolutions:

          WHEREAS, the officers of the Corporation recommended that
          the Corporation reincorporate under the laws of the State
          of Oklahoma and the Board of Directors, after discussing
          the issue, has determined that the reincorporation is in
          the best interest of the shareholders and the
          Corporation; and

          WHEREAS, to facilitate the Corporation's reincorporation,
          the officers of the Corporation  recommended that the
          Corporation form Chesapeake Oklahoma Corporation
          ("Chesapeake Oklahoma") to be organized and exist under
          and by virtue of the laws of the State of Oklahoma, with
          an authorized capitalization of (i) 100 million shares of
          common stock, $.01 par value ("Chesapeake Oklahoma Common
          Stock"), 10 shares of which will be issued and
          outstanding prior to the reincorporation, and (ii) 10
          million shares of preferred stock, $.01 par value, no
          shares of which will be issued and outstanding prior to
          the reincorporation  (all shares of Chesapeake Oklahoma
          Common Stock outstanding prior to the reincorporation
          will be held of record and beneficially by the
          Corporation).

          NOW, THEREFORE, BE IT RESOLVED, that the officers of the
          Corporation be, and each of them hereby is, authorized
          and directed to take any and all actions required to
          reincorporate the Corporation under the laws of the State
          of Oklahoma, including without limitation, the forming of
          Chesapeake Oklahoma as a new transitory subsidiary, in
          accordance with the recitations set forth herein, the
          listing of the shares of Chesapeake Oklahoma on the New
          York Stock Exchange, the registration of such shares with
          the Securities and Exchange Commission and any state
          securities agency, the assumption by Chesapeake Oklahoma
          of all existing plans and registration statements of the
          Corporation and such other actions as may be necessary to
          the effect that the rights and obligations of Chesapeake
          Oklahoma will be virtually identical to the rights and
          obligations of the Corporation.

          WHEREAS, after the formation of Chesapeake Oklahoma, the
          Board of Directors deems it advisable and in the best
          interests of the Corporation and its shareholders that
          the Corporation merge with and into Chesapeake Oklahoma
          pursuant to Section 1083 of the Oklahoma General
          Corporation Act and Section 253 of the Delaware General
          Corporation Law (the "Merger") and immediately thereafter
          for Chesapeake Oklahoma to change its name to Chesapeake
          Energy Corporation; and

          WHEREAS, the Corporation and Chesapeake Oklahoma will
          hereinafter be know as the "Constituent Corporations;"
          and 

          WHEREAS, the Board of Directors deems it advisable and in
          the best interests of the Corporation and its
          shareholders that the Corporation be merged with and into
          Chesapeake Oklahoma in the manner contemplated herein
          (the "Plan") and recommend that the Merger and the Plan
          be approved and adopted by the shareholders of the
          Corporation;

          NOW, THEREFORE, BE IT RESOLVED, that the Constituent
          Corporations will be merged into a single corporation by
          the Corporation merging with and into Chesapeake
          Oklahoma, which will survive the Merger, pursuant to the
          provisions of Section 1083 of the Oklahoma General
          Corporation Act and Section 253 of the Delaware General
          Corporation Law.  Upon such Merger, the separate
          existence of the Corporation will cease, and Chesapeake
          Oklahoma will become the owner, without transfer, of all
          rights and property of the Constituent Corporations, and
          will be subject to all the liabilities of the Constituent
          Corporations in the same manner as if Chesapeake Oklahoma
          had itself incurred such liabilities all as provided by
          the Oklahoma General Corporation Act.
<PAGE>   23
          FURTHER RESOLVED, that, on the Effective Date of the
          Merger, which will be 5:00 p.m., CST, on December 31,
          1996 (the "Effective Date of the Merger"), the
          Certificate of Incorporation and Bylaws of Chesapeake
          Oklahoma, as currently in effect, will be the Certificate
          of Incorporation and Bylaws of Chesapeake Oklahoma until
          they are duly amended, except that the name of Chesapeake
          Oklahoma will be changed to Chesapeake Energy
          Corporation.

          FURTHER RESOLVED, that on the Effective Date of the
          Merger, the directors and officers of the Corporation
          will become the directors and officers of Chesapeake
          Oklahoma until their successors are duly elected and
          qualified.

          FURTHER RESOLVED, that on the Effective Date of the
          Merger (i) each share of Chesapeake Common Stock issued
          and outstanding immediately prior to the Effective Date
          of the Merger, by virtue of the Merger and without any
          action on the part of the holder thereof, will be
          converted into one share of Chesapeake Oklahoma Common
          Stock, (ii) each share of Chesapeake Oklahoma Common
          Stock issued and outstanding immediately prior to the
          Effective Date of the Merger, by virtue of the Merger and
          without any action on the part of the holder thereof,
          will be cancelled and no payment will be made in respect
          thereof, and (iii) upon surrender of any certificates
          representing Chesapeake Common Stock, stock certificates
          representing Chesapeake Oklahoma Common Stock will be
          reissued to the holder thereof.

          FURTHER RESOLVED, that this Plan will be submitted to the
          shareholders of the Corporation for approval in the
          manner provided by applicable Oklahoma and Delaware law. 
          After approval by the vote of the holders representing
          not less than a majority of the issued and outstanding
          shares of Chesapeake Common Stock entitled to vote on the
          Merger, the officers are, and each of them hereby is,
          authorized and directed to execute and file with the
          Secretary of State of the States of Oklahoma and Delaware
          a Certificate of Ownership and Merger and to make any

          the Merger.

          FURTHER RESOLVED, that the officers of the Corporation
          are authorized and directed to execute any and all
          agreements, documents or consents, and to take any and
          all actions deemed necessary or desirable to permit the

          The execution by the officers, or any one of them, of any
          such document or agreement, or the doing by them of any
          act in connection with the foregoing matter, will
          conclusively establish their authority therefor from this
          Board and from the Corporation and the approval,
          ratification and adoption of any documents or agreements
          executed and any action taken.

          FURTHER RESOLVED, that the officers of the Corporation

be paid or set apart for payment before any dividends shall be paid
or declared or set apart for payment on the common shares with
respect to the same dividend period.
<PAGE>   27

          If upon any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation the assets available
for distribution to holders of shares of Preferred Stock of all
series shall be insufficient to pay such holders the full
preferential amount to which they are entitled, then such assets
shall be distributed ratably among the shares of all series in
accordance with the respective preferential amounts (including
unpaid cumulative dividends, if any) payable with respect thereto.

          Section 2.     Common Stock.  The Common Stock
shall be subject to the express terms of the Preferred Stock and
any series thereof.  Each share of Common Stock shall be equal to
every other share of Common Stock.  The holders of shares of Common
Stock shall be entitled to one vote for each share of such stock
upon all matters presented to the shareholders.  Shares of Common
Stock authorized hereby shall not be subject to preemptive rights. 
The holders of shares of Common Stock now or hereafter outstanding
shall have no preemptive right to purchase or have offered to them
for purchase any of such authorized but unissued shares.  The
holders of shares of Common Stock now or hereafter outstanding
shall have no preemptive right to purchase or have offered to them
for purchase any shares of Preferred Stock, Common stock, or other
equity securities issued or to be issued by the Company.

          Subject to the preferential and other dividend rights
applicable to Preferred Stock, the holders of shares of Common
Stock shall be entitled to receive such dividends (payable in cash,
stock or otherwise) as may be declared on the Common Stock by the
Board of Directors at any time or from time to time out of any

          In the event of any voluntary or involuntary liquidation,

in full of the preferential and/or other amounts to be distributed

                            ARTICLE VI

                     Certain Stock Purchases

          Section 1.     Certain Definitions.  For the
purposes of this Article VI:

          "Continuing Director" means any member of the Board of
Directors of the Corporation (the "Board") who is unaffiliated with
the Interested Shareholder and was a member of the Board prior to
the time that the Interested Shareholder became an Interested
Shareholder, and any successor of a Continuing Director who is
unaffiliated with the Interested Shareholder and is recommended to
succeed a Continuing Director by a majority of Continuing Directors
then on the Board.

          "Exchange Act" shall mean the Securities Exchange Act of
1934, as amended.

          "Fair Market Value" means:  (1) in the case of stock, the
highest closing sale price during the 30-day period ending on the
date in question of a share of such stock on a principal United
States securities exchange registered under the Exchange Act on
which such stock is listed or in the national market system
maintained by the National Association of Securities Dealers, Inc.,
or, if the stock is not listed on any such exchange or designated
as a national market system security, the highest closing bid
quotation with respect to a share of such stock during the 30-day
period ending on the date in question on the National Association
of Securities Dealers, Inc. Automated Quotations system or any
system then in use, or if no such quotations are available, the
fair market value on the date in question of a share of such stock
as determined by the Board in good faith.

          "Interested Shareholder" shall have the meaning ascribed
to such term under Section 1090.3 of the Act.

          Section 2.     Vote Required for Certain Stock
Purchases.

               A.   Any direct or indirect purchase by the Corporation, or
any subsidiary of the Corporation, of any capital stock from a
person or persons known by a majority of the Continuing Directors
of the Corporation to be an Interested Shareholder who has
beneficially owned such capital stock for less than three years
prior to the date of such purchase, or any agreement in respect
thereof, at a price in excess of the Fair Market Value shall
require the affirmative vote of no less than 66 2/3% of the votes
cast by the holders, voting together as a single class, of all then
outstanding shares of capital stock, excluding for this purpose the
votes by the Interested Shareholder, unless a greater vote shall be
required by law.

               B.   Such affirmative vote shall not be required for a
purchase or other acquisition of securities of the same class made
on substantially the same terms to all holders of such securities
and complying with the applicable requirements of the Exchange Act,
and the rules and regulations thereunder (or any subsequent
provisions replacing the Exchange Act, rules or regulations). 
Furthermore, such affirmative vote shall not be required for any
purchase effected on the open market and not the result of a
privately-negotiated transaction.

          Section 3.     Powers of Continuing Directors. 
The Continuing Directors of the Corporation shall have the power
and duty to determine for the purposes of this Article VI, on the
basis of information known to them after reasonable inquiry,
whether a person is an Interested Shareholder, and the number of
shares of capital stock owned beneficially by any person.

                           ARTICLE VII

                        Board of Directors
          
          Section 1.     Management by Board of Directors. 
The business and affairs of the Corporation shall be under the
direction of the Board of Directors.

          Section 2.     Number of Directors.  The number
of Directors which shall constitute the whole board shall be not
less than three nor more than fifteen, and shall be determined by
resolution adopted by a vote of two-thirds (2/3) of the entire
board, or at an annual or special meeting of shareholders by the
affirmative vote of sixty-six and two-third percent (66 2/3%) of
the outstanding stock entitled to vote.  No reduction in number
shall have the effect of removing any director prior to the
expiration of his term.  The number of directors of the Corporation
may, from time to time, be increased or decreased in such manner as
may be provided in the bylaws of the Corporation.

          Section 3.     Classes of Directors; Election by
Shareholders; Vacancies.  The directors shall be divided into three
classes, designated Class I, Class II and Class III.  Each class
shall consist, as nearly as may be possible, of one-third of the
total number of directors constituting the entire Board of
Directors.  The term of the initial Class I directors shall
terminate on the date of the 1997 annual meeting of shareholders;
the term of the initial Class II directors shall terminate on the
date of the 1998 annual meeting of shareholders and the term of the
initial Class III directors shall terminate on the date of the 1999
annual meeting of shareholders.  At each annual meeting of
shareholders beginning in 1997, successors to the class of
directors whose term expires at that annual meeting shall be
elected for a three-year term.  If the number of directors is
changed, any increase or decrease shall be apportioned among the
classes so as to maintain the number of directors in each class as
nearly equal as possible, and any additional directors of any class
elected to fill a vacancy resulting from an increase in such class
shall hold office for a term that shall coincide with the remaining
term of that class, but in no case will a decrease in the number of
directors shorten the term of any incumbent director.  A director
shall hold office until the annual meeting for the year in which
his term expires and until his successor shall be elected and shall
qualify, subject, however, to prior death, resignation, retirement,
disqualification or removal from office.  Any vacancy on the Board
of directors, however resulting, may be filled by a majority of the
directors then in office, even if less than a quorum, or by a sole
remaining director.  Any director elected to fill a vacancy shall
hold office for a term that shall coincide with the term of the
class to which such director shall have been elected.  No election
of directors need be by written ballot.
          
                                Notwithstanding the foregoing,
whenever the holders of any one or more classes or series of
Preferred Stock issued by the Corporation shall have the right,
voting separately by class or series, to elect directors at an
annual or special meeting of shareholders, the election, term of
office, filling of vacancies and other features of such
directorships shall be governed by the terms of the Certificate of
Designation attributable to such Preferred stock or the resolution
or resolutions adopted by the Board of Directors pursuant to
Section 2 of this Article VII applicable thereto, and such
directors so elected shall not be divided into classes pursuant to
this Article VII unless expressly provided by such terms.

                           ARTICLE VIII

                            Indemnity
          
          Section 1.     Third Party Claims.  The
Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or
completed action, suit or proceeding whether civil, criminal,
administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that he is or was
a director, officer, employee or agent of the Corporation or is or
was serving at the request of the Corporation as a director,
officer, employee or agent of another corporation, partnership,
joint venture or other enterprise against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such
action, suit or proceeding, if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best
interest of the Corporation and, with respect to any criminal
action or proceeding, had no reasonable cause to believe that his
conduct was unlawful.  The termination of any action, suit or
proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent shall not of itself
create a presumption that the person did not act in good faith and
in a manner which he reasonably believed to be in or not opposed to
the best interest of the Corporation and with respect to any
criminal action or proceeding had reasonable cause to believe that
his conduct was unlawful.

          Section 2.     Derivative Claims.  The Corporation
shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action
or suit by or in the right of the Corporation to procure a judgment
in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation or is or was serving
at the request of the Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust
or other enterprise against expenses (including attorney's fees)
actually and reasonably incurred by him in connection with the
defense or settlement of such action or suit, if he acted in good
faith and in a manner he reasonably believed to be in or not
opposed to the best interest of the Corporation; except that no
indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the
court in which such action or suit was brought shall determine,
upon application, that despite the adjudication of liability, but
in the view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which
the court shall deem proper.

          Section 3.     Expenses.  Expenses, including fees
and expenses of counsel, incurred in defending a civil, criminal,
administrative or investigative action, suit or proceeding may be
paid by the Corporation in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on
behalf of the director, officer, employee or agent to repay such
amount if it shall ultimately be determined that he is not entitled
to be indemnified by the Corporation as authorized herein.

          Section 4.     Insurance.  The Corporation may
purchase (upon resolution duly adopted by the board of directors)
and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director,
officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability.
<PAGE>   31

          Section 5.      Reimbursement.  To the extent that
a director, officer, employee or agent of, or any other person
entitled to indemnity hereunder by, the Corporation has been
successful on the merits or otherwise in defense of any action,
suit, or proceeding referred to herein or in defense of any claim,
issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him
in connection therewith.

          Section 6.       Enforcement.  Every such person
shall be entitled, without demand by him upon the Corporation or
any action by the Corporation, to enforce his right to such
indemnity in an action at law against the Corporation.  The right
of indemnification and advancement of expenses hereinabove provided
shall not be deemed exclusive of any rights to which any such
person may now or hereafter be otherwise entitled and specifically,
without limiting the generality of the foregoing, shall not be
deemed exclusive of any rights pursuant to statute or otherwise, of
any such person in any such action, suit or proceeding to have
assessed or allowed in his favor against the Corporation or
otherwise, his costs and expenses incurred therein or in connection
therewith or any part thereof.


                            ARTICLE IX

     Amendments; Bylaws; Control Shares Act; Written Consent

          Section 1.     Amendments to Certificate of
Incorporation.  Notwithstanding anything contained in this
Certificate of Incorporation to the contrary, the affirmative vote
of the holders of at least sixty-six and two-thirds percent (66
2/3%) of the issued and outstanding stock having voting power,
voting together as a single class, shall be required to amend,
repeal or adopt any provision inconsistent with Articles V, VI,
VII, VIII and this Article IX of this Certificate of Incorporation.

          Section 2.      Bylaws.  Prior to the receipt of
any payment for any of the Corporation's stock, the Bylaws of the
Corporation shall be adopted, amended or repealed by the
Incorporator.  Thereafter, in furtherance and not in limitation of
the powers conferred by statute, the Board of Directors is
expressly authorized to adopt, repeal, alter, amend or rescind the
Bylaws of the Corporation.  In addition, the Bylaws of the
Corporation may be adopted, repealed, altered, amended, or
rescinded by the affirmative vote of the holders of sixty-six and
two-thirds percent (66 2/3%) of the outstanding stock of the
Corporation entitled to vote thereon.

          Section 3.      Control Shares Act.  The
Corporation shall not be subject to the Oklahoma Control Shares Act
as codified at Sections 1145-1155 of the Act.  This election shall
be effective on the date of filing this Certificate.

          Section 4.      Action By Written Consent.  Any
action required or permitted to be taken at a meeting of the
shareholders may be taken without a meeting, without prior notice
and without a vote, if a consent in writing, setting forth the
action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes which would
be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted.  Prompt
notice of the taking of corporate action without a meeting by less
than unanimous written consent shall be given to those shareholders
who have not consented in writing.

listed as signatories hereto, and United States Trust Company of New York, a
New York corporation, as Trustee.

                 Each party agrees as follows for the benefit of the other
parties and for the equal and ratable benefit of the holders of the Company's
Series A and Series B 9 5/8% Senior Notes due 2005:

                                  ARTICLE ONE

                   DEFINITIONS AND INCORPORATION BY REFERENCE

SECTION 1.01.    Definitions.

                 "Adjusted Consolidated EBITDA" means the Consolidated Net
Income of the Company and its Restricted Subsidiaries for the Reference Period,
(a) increased (to the extent deducted in determining Consolidated Net Income)
by the sum, without duplication, of: (i) all income and state franchise taxes
of the Company and its Restricted Subsidiaries paid or accrued according to
GAAP for such period (other than income taxes attributable to extraordinary,
unusual or non-recurring gains or losses); (ii) all interest expense of the
Company and its Restricted Subsidiaries paid or accrued in accordance with GAAP
for such period (including amortization of original issue discount); (iii)
depreciation and depletion of the Company and its Restricted Subsidiaries; (iv)
amortization of the Company and its Restricted Subsidiaries including, without
limitation, amortization of capitalized debt issuance costs; (v) any loss
realized in accordance with GAAP upon the sale or other disposition of any
property, plant or equipment of the Company or its Restricted Subsidiaries
(including pursuant to any Sale/Leaseback Transaction) which is not sold or
otherwise disposed of in the ordinary course of business and any loss realized
in accordance with GAAP upon the sale or other disposition of any Capital Stock
of any Person; (vi) any loss realized in accordance with GAAP from currency
exchange transactions not in the ordinary course of business consistent with
past practice; (vii) any loss realized in accordance with GAAP attributable to
extraordinary items; (viii) any charges associated solely with the prepayment
of any Indebtedness; and (ix) any other non-cash charges to the extent deducted
from Consolidated Net Income and (b) decreased (to the extent included in
determining Consolidated Net Income) by the sum of (i) the amount of deferred
revenues that are amortized during the Reference Period and are attributable to
reserves that are subject to Volumetric Production Payments and (ii) amounts
recorded in accordance with GAAP as repayments of principal and interest
pursuant to Dollar-Denominated Production Payments.

                 "Adjusted Consolidated EBITDA Coverage Ratio" means, for any
Reference Period, the ratio on a pro forma basis of (a) Adjusted Consolidated
EBITDA for the Reference Period to (b) Adjusted Consolidated Interest Expense
for such Reference Period; provided, that, in calculating Adjusted Consolidated
EBITDA and Adjusted Consolidated Interest Expense (i) acquisitions which
occurred during the Reference Period or subsequent to the Reference Period and
on or prior to the date of the transaction giving rise to the need to calculate
the Adjusted Consolidated EBITDA Coverage Ratio (the "Transaction Date") shall
be assumed to have occurred on the first day of the Reference Period, (ii) the
incurrence of any Indebtedness (including the issuance of the Securities) or
issuance of any Disqualified Stock during the Reference Period or subsequent to
the Reference Period and on or prior to the Transaction Date shall be assumed
to have occurred on the first day of such Reference Period, (iii) any
Indebtedness that had been outstanding during the Reference Period that has
been repaid on or prior to the Transaction Date shall be assumed to have been
repaid as of the first day of such Reference Period, (iv) the Adjusted
Consolidated Interest Expense attributable to interest on any Indebtedness or
dividends on any Disqualified Stock bearing a floating interest (or dividend)
rate shall be computed on a pro forma basis as if the rate in effect on the
Transaction Date were the average rate in effect during the entire Reference
Period and (v) in determining the amount of Indebtedness pursuant to Section
4.09, the incurrence of Indebtedness or issuance of Disqualified Stock giving
rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio
and, to the extent the net proceeds from the incurrence or issuance thereof are
used to retire Indebtedness, the application of the proceeds therefrom shall be
assumed to have occurred on the first day of the Reference Period.

                 "Adjusted Consolidated Interest Expense" means, with respect
to the Company and its Restricted Subsidiaries, for the Reference Period, the
aggregate amount (without duplication) of (a) interest expensed in accordance
with GAAP (including, in accordance with the following sentence, interest
attributable to Capitalized Lease Obligations, but excluding interest
attributable to Dollar-Denominated Production Payments and amortization of
deferred debt
<PAGE>   8
expense) during such period in respect of all Indebtedness of the Company and
its Restricted Subsidiaries (including (i) amortization of original issue
discount on any Indebtedness (other than with respect to the Existing Notes and
the Securities), (ii) the interest portion of all deferred payment obligations,
calculated in accordance with GAAP, and (iii) all commissions, discounts and
other fees and charges owed with respect to bankers' acceptance financings and
currency and interest rate swap arrangements, in each case to the extent
attributable to such period), and (b) dividend requirements of the Company and
its Restricted Subsidiaries with respect to any Preferred Stock dividends
(whether in cash or otherwise (except dividends paid solely in shares of
Qualified Stock)) paid (other than to the Company or any of its Restricted
Subsidiaries), declared, accrued or accumulated during such period, divided by
one minus the applicable actual combined federal, state, local and foreign
income tax rate of the Company and its Subsidiaries (expressed as a decimal),
on a consolidated basis, for the four quarters immediately preceding the date
of the transaction giving rise to the need to calculate Consolidated Interest
Expense, in each case to the extent attributable to such period and excluding
items eliminated in consolidation. For purposes of this definition, (a)
interest on a Capitalized Lease Obligation shall be deemed to accrue at an
interest rate reasonably determined by the Company to be the rate of interest
implicit in such Capitalized Lease Obligation in accordance with GAAP and (b)
interest expense attributable to any Indebtedness represented by the guarantee
by the Company or a Restricted Subsidiary of the Company of an obligation of
another Person shall be deemed to be the interest expense attributable to the
Indebtedness guaranteed.

                 "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
proved 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 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





                                      -2-
<PAGE>   9
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

using the full cost method of accounting.

such date and (ii) the amount by which the present fair saleable value of the
assets of such Subsidiary Guarantor at such date exceeds the amount that will
be required to pay the probable liability of such Subsidiary Guarantor on its
debts (after giving effect to all other fixed and contingent liabilities
incurred or assumed on such date and after giving effect to any collection from
any Subsidiary of such Subsidiary Guarantor in respect of the obligations of
such Subsidiary under the Guarantee), excluding debt in respect of the
Guarantee, as they become absolute and matured.

of the Company's oil and gas production operations, (c) any abandonment,

compliance with Article Five, (e) Sale/Leaseback Transactions in compliance
with Section 4.13, (f) the provision of services and equipment for the

such insertions, omissions, substitutions and variations as are required or as

Indenture and, to the extent applicable, the Company and the Subsidiary
Guarantors, by their execution and delivery of this Indenture, expressly agree
to such terms and provisions and to be bound thereby.

                 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

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

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

Securities for original issue in the aggregate principal amount of $500,000,000
upon a written order of the Company signed by two Officers of the Company.  The

payable to the Depositary 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

                 The Trustee may appoint an authenticating agent to

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.

                 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 2.03.    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 Depositary Trust Company
("DTC") to act as Depositary with respect to the Global Securities.  Cede & Co.
has been appointed as the nominee of DTC.

                 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 2.04.    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, it shall segregate and hold as separate trust funds for the
benefit of the Holders all money held by it as Paying Agent.

SECTION 2.05.    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 10 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 2.06.    Transfer and Exchange.

                 (a)      Exchange of Beneficial Interests in Global Security
for Certificated Security.  Beneficial interests in a Global Security may,
subject to the restrictions on the transferability of the Securities, 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
Depositary (in accordance with the Depositary's customary procedures) and will
bear the applicable legends set forth in Exhibit A hereto.

                 (b)      Surrender for Exchange of Global Securities.  If any
Global Security is to be exchanged for other Securities or canceled in whole,
it shall be surrendered by or on behalf of the Depositary or its nominee to the
Trustee, as Registrar, for exchange or cancellation as provided in this Article
Two.  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 Two or, if the Trustee is acting as custodian for the Depositary 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 Depositary 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 Two, 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 Depositary 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 (k) 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 Depositary or its authorized representative which is given or made pursuant
to this Article Two if such order, direction or request is given or made in
accordance with the Applicable Procedures.

                 (c)      Proxies by Registered Holder.  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)      Interests of Agent Members and Depositary in Global
Security.  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 Depositary or under the Global
Security, and the Depositary 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 Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practice governing the
exercise of the rights of a Holder of any Security.

                 (e)      Transfers of Securities.  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





                                      -19-
<PAGE>   26
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 2.06, 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 2.06,
shall only be made in accordance with this Section 2.06.  Transfers and
exchanges subject to this Section 2.06 shall also be subject to the other
provisions of this Indenture that are not inconsistent with this Section 2.06.

                 (f)      General.  A Global Security may not be transferred,
in whole or in part, to any Person other than the Depositary 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 render ineffective any transfer of a beneficial interest in a
Global Security effected in accordance with the other provisions of this
Section 2.06.

                 (g)      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 (including the
certification requirements intended to insure that transfers of beneficial
interests in a Global Security comply with Rule 144A under the Securities Act),
as may from time to time be adopted by the Company and the Trustee.

                 (h)      Transfers of Certificated Securities.  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 its 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
2.02, 2.10, 3.07 or 9.05).  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.

                 (i)      Exchange of Certificated Series A Notes for
Book-Entry Security.  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, may exchange such Security for a Global Security by
instructing the Trustee 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 Depositary.

                 (j)      Execution and Authentication of Certificated
Securities.  Upon any exchange provided for in Section 2.06(a), the Company
shall execute and the Trustee shall authenticate, and deliver to the person
specified by the Depositary a new Series A Note or Notes registered in such
names and in such authorized denominations as the Depositary, 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 Depositary 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 Depositary in accordance with the procedures of
the Depositary therefor.





                                      -20-
<PAGE>   27
                 (k)      Registration of Global Security in Name Other than
Depositary.  Notwithstanding the foregoing, no Global Security shall be
registered for transfer or exchange, or authenticated and delivered, whether
pursuant to this Section, Section 2.07, 2.10 or 3.06 or otherwise, in the name
of a person other than the Depositary for such Global Security or its nominee
until (i) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or if at any time the
Depositary ceases to be a clearing agency registered under the Exchange Act,
and a successor depositary is not appointed by the Company within 30 days, (ii)
the Company executes and delivers to the Trustee a Company Order 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 Securities 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 Securities
registered in the names of, authenticated and delivered to, such persons as the
Trustee or the Depositary, as the case may be, shall direct.

                 (l)      Delivery of Securities Upon Transfer or Exchange of
Global Security.  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 2.07, 2.10 or 3.06 or
otherwise, shall also be a Global Security and bear the legend specified in
footnote 1 to Exhibit A.

SECTION 2.07.    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 2.08.    Outstanding Securities.

                 Securities 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 2.08 as not outstanding.  Except as set forth in
Section 2.09, 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 2.07, it ceases
to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Securities is held by a bona fide purchaser.

                 If the principal amount of any Security is considered paid
under Section 4.01, it ceases to be outstanding and interest on it ceases to
accrue.

SECTION 2.09.    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, 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.

<PAGE>   28
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 2.07, 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, that are
repurchased by the Company pursuant to Section 4.11 or Section 4.16, 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 4.01 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 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 THREE

                                   REDEMPTION

SECTION 3.01.    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





                                      -22-
<PAGE>   29
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 3.02.    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 3.03.    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.

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

                          (1)     the redemption date;

                          (2)     the redemption price;

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

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

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

                          (6)     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;

                          (7)     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;

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

                          (9)     the CUSIP number of the Securities.

                 (b)      At the Company's request, the Trustee shall give the
notice of redemption required in Section 3.03(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 3.03(a).





                                      -23-
<PAGE>   30
SECTION 3.04.    Effect of Notice of Redemption.

                 Once notice of redemption is mailed in accordance with Section
3.03, 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 redemption date.

SECTION 3.05.    Deposit of Redemption Price.

                 Prior to the redemption date, the Company shall deposit with
the Paying Agent funds available on the redemption date sufficient to pay the
redemption price of, and accrued and unpaid interest on, the Securities to be
redeemed on that date.  The Paying Agent shall promptly return to the Company
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 3.06.    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 3.07.    Optional Redemption.

                 Except as set forth in Sections 3.08 and 3.09 hereof, the
Company shall not have the option to redeem the Securities prior to May 1,
2002.  The Securities may be redeemed at the option of the Company, in whole or
from time to time in part, at any time on or after May 1, 2002, at the
redemption prices set forth below (expressed as a percentage of the principal
amount of the Securities to be redeemed), together with accrued and unpaid
interest on the Securities so redeemed to the redemption date, if redeemed
during the 12-month period commencing on May 1 of the years indicated below:

hereof.

SECTION 3.08.    Equity Offering Redemption.

                 In the event the Company consummates one or more Equity
Offerings on or prior to May 1, 2001, the Company may redeem, in its sole
discretion, up  to $167,000,000 of the aggregate principal amount of the
Securities with all or a portion of the aggregate net proceeds received by the
Company from any such Equity Offering or Equity Offerings at a redemption price
of 109.625% of the aggregate principal amount of the Securities so redeemed,
plus accrued and unpaid interest on the Securities so redeemed to the
redemption date; provided, however, that (i) the date of any such redemption
occurs within the 90-day period after the Equity Offering in respect of which

SECTION 4.03.    Compliance Certificates.

                 (a)      The Company shall deliver to the Trustee, within 90
days after the end of each fiscal year of the Company, an Officers' Certificate
substantially in the form of Exhibit J hereto, stating that a review of the
activities of the Company and the Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its

signing such certificate, that, to the best of such Officer's knowledge, the
Company and each Subsidiary Guarantor has kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and is not in

conditions hereof (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which such Officer may
have knowledge and what action the Company is taking or proposes to take with
respect thereto) and that to the best of such Officer's knowledge, after
reasonable inquiry, no event has occurred and remains in existence by reason of
which payments on account of the principal of, premium, if any, or interest, if
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
Guarantors are taking or propose to take with respect thereto.  Such Officers'

hereby covenants that it shall notify the Trustee at least 30 days in advance
of any change in its fiscal year.

                 (b)      So long as not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
year-end financial statements delivered pursuant to Section 4.02 shall be
accompanied by a written statement of the Company's independent public
accountants (which shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial statements
nothing has come to their attention that would lead them to believe that the
Company has violated any provisions of Sections 4.07, 4.09, 4.10, 4.11 or 4.15
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 recommendations of the American Institute of Certified Public
Accountants.

                 (c)      The Company and the Subsidiary Guarantors will, so
long as any of the Securities are outstanding, deliver to the Trustee forthwith
upon any Officer becoming aware of any Default or Event of Default or default
in the performance of any covenant, agreement or condition contained in this
Indenture, an Officers' Certificate specifying such Default or Event of Default
and what action the Company or any Subsidiary Guarantor proposes to take with

SECTION 4.04.    Maintenance of Office or Agency.

                 The Company will maintain in the Borough of Manhattan, The
City of New York, an office or agency where Securities may be surrendered for
registration of transfer or exchange or for presentation for payment and where
notices and demands to or upon the Company in respect of the Securities and
this Indenture may be served.  The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at
the address of the Trustee set forth in Section 11.02.  If at any time the
Company shall fail to maintain any required office or agency or shall fail to
furnish the Trustee with the address thereof, such surrenders, presentations,
notices and demands may be made or served at the corporate trust office of the
Trustee.

                 Subject to Section 2.03, the Company may also from time to
time designate one or more other offices or agencies where the Securities may
be presented or surrendered for any or all such purposes and may from time to
time rescind such designations; provided, that no such designation or
rescission shall in any manner relieve the Company of its 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.

SECTION 4.05.    Corporate Existence.

                 The Company will do or cause to be done all things necessary
to preserve and keep in full force and effect its corporate existence and the
corporate, partnership or other existence of each Subsidiary and all rights
(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
Directors of the Company shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the
loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 4.06.    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 4.07.    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) all lawful claims for labor, materials and supplies which, if unpaid, might
by law become a Lien upon the property of the Company or any Subsidiary;
provided, however, that the Company shall not be required to pay or discharge
or cause to be paid or discharged any such tax, assessment, charge or claim
whose amount, applicability or validity is being contested in good faith by
appropriate proceedings.

SECTION 4.08.    Maintenance of Properties and Insurance.

                 (a)      The Company shall cause all properties used or held
for use in the conduct of its business or the business of any Subsidiary to be
maintained and kept in good condition, repair and working order (ordinary wear
and tear excepted) and supplied with all necessary equipment and shall cause to
be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so
that the business carried on 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 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
Company, for corporations similarly situated in the industry.

SECTION 4.09.    Limitation on Incurrence of Additional Indebtedness.

                 (a)      The Company will not, and will not permit any of its
Restricted Subsidiaries, directly or indirectly, to issue, incur, assume,
guarantee, become liable, contingently or otherwise, with respect to or
otherwise become responsible for the payment of (collectively, "incur") any
Indebtedness; provided, however, that if no Default





                                      -27-
<PAGE>   34
or Event of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of such Indebtedness, the Company or its
Restricted Subsidiaries may incur Indebtedness if, on a pro forma basis, after
giving effect to such incurrence and the application of the proceeds therefrom,
either of the following tests shall have been satisfied: (i) the Adjusted
Consolidated EBITDA Coverage Ratio would have been at least 2.25 to 1.0; or
(ii) Adjusted Consolidated Net Tangible Assets would have been equal to or
greater than 200% of Indebtedness of the Company and its Restricted
Subsidiaries.

                 (b)      Notwithstanding the foregoing, if no Default or Event
of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of such Indebtedness, the Company and its
Restricted Subsidiaries may incur Permitted Indebtedness.

                 (c)      Any Indebtedness of a Person existing at the time
such Person becomes a Restricted Subsidiary (whether by merger, consolidation,
acquisition or otherwise) shall be deemed to be incurred by such Restricted
Subsidiary at the time it becomes a Restricted Subsidiary.

SECTION 4.10.    Limitation on Restricted Payments.

                 (a)      The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, make any Restricted
Payment, unless:

                          (i)     no Default or Event of Default shall have
                 occurred and be continuing at the time of or immediately after
                 giving effect to such Restricted Payment;

                          (ii)    at the time of and immediately after giving
                 effect to such Restricted Payment, the Company would be able
                 to incur at least $1.00 of additional Indebtedness (other than
                 Permitted Indebtedness) pursuant to Section 4.09(a); and

                          (iii)   immediately after giving effect to such
                 Restricted Payment, the aggregate of all Restricted Payments
                 declared or made after the Issue Date does not exceed the sum
                 of (A) 50% of the Consolidated Net Income of the Company and
                 its Restricted Subsidiaries (or in the event such Consolidated
                 Net Income shall be a deficit, minus 100% of such deficit)
                 during the period (treated as one accounting period)
                 subsequent to March 31, 1998 and ending on the last day of the
                 fiscal quarter immediately preceding the date of such
                 Restricted Payment; (B) the aggregate Net Cash Proceeds, and
                 the fair market value of property other than cash (as
                 determined in good faith by the Company's Board of Directors,
                 including a majority of the Company's Disinterested Directors,
                 and evidenced by a resolution of such Board), received by the
                 Company during such period from any Person other than a
                 Subsidiary of the Company as a result of the issuance or sale
                 of Capital Stock of the Company (other than any Disqualified
                 Stock and other than Preferred Shares issued in the Preferred
                 Stock Offering), other than in connection with the conversion
                 of Indebtedness or Disqualified Stock; (C) the aggregate Net
                 Cash Proceeds, and the fair market value of property other
                 than cash (as determined in good faith by the Company's Board
                 of Directors and evidenced by a resolution of such Board),
                 received by the Company during such period from any Person
                 other than a Subsidiary of the Company as a result of the
                 issuance or sale of any Indebtedness or Disqualified Stock to
                 the extent that at the time the determination is made such
                 Indebtedness or Disqualified Stock, as the case may be, has
                 been converted into or exchanged for Capital Stock of the
                 Company (other than Disqualified Stock); (D)(i) in case any
                 Unrestricted Subsidiary has been redesignated a Restricted
                 Subsidiary, an amount equal to the lesser of (x) the book
                 value (determined in accordance with GAAP) at the date of such
                 redesignation of the aggregate Investments made by the Company
                 and its Restricted Subsidiaries in such Unrestricted
                 Subsidiary and (y) the fair market value of such Investments
                 in such Unrestricted Subsidiary at the time of such
                 redesignation, as determined in good faith by the Company's
                 Board of Directors, including a majority of the Company's
                 Disinterested Directors, whose determination shall be
                 conclusive and evidenced by a resolution of such Board; or
                 (ii) in case any Restricted Subsidiary has been redesignated
                 an Unrestricted Subsidiary, minus the greater of (x) the book
                 value (determined in accordance with GAAP) at the date of
                 redesignation of the aggregate Investments made by the





                                      -28-
<PAGE>   35
                 Company and its Restricted Subsidiaries in such Restricted
                 Subsidiary and (y) the fair market value of such Investments
                 in such Restricted Subsidiary at the time of such
                 redesignation, as determined in good faith by the Company's
                 Board of Directors, including a majority of the Company's
                 Disinterested Directors, whose determination shall be
                 conclusive and evidenced by a resolution of such Board; and
                 (E) $25,000,000.

                 (b)      Notwithstanding the foregoing, the above limitations
will not prevent (i) the payment of any dividend within 60 days after the date
of declaration thereof, if at such date of declaration such payment complied
with the provisions hereof; (ii) the purchase, redemption, acquisition or
retirement of any shares of Capital Stock of the Company in exchange for, or
out of the net proceeds of the substantially concurrent sale (other than to a
Restricted Subsidiary of the Company) of, other shares of Capital Stock (other
than Disqualified Stock) of the Company; and (iii) any dividend or other
distribution payable from a Subsidiary to the Company or any Restricted
Subsidiary.

SECTION 4.11.    Limitation on Sale of Assets.

                 (a)      The Company will not, and will not permit any
Restricted Subsidiary to, make any Asset Sale unless:

                          (i) the Company (or its Restricted Subsidiaries, as
                 the case may be) receives consideration at the time of such
                 sale or other disposition at least equal to the fair market
                 value thereof (as determined in good faith by the Company's
                 Board of Directors and evidenced by a resolution of such
                 Board, including a majority of the Company's Disinterested
                 Directors, in the case of any Asset Sales or series of related
                 Asset Sales having a fair market value of $20,000,000 or
                 greater);

                          (ii) at least 75% of the proceeds from such Asset
                 Sale consist of cash, cash equivalents or property, equipment,
                 leasehold interests or other assets used in the Oil and Gas
                 Business; and

                          (iii) the Net Available Proceeds received by the
                 Company (or its Restricted Subsidiaries, as the case may be)
                 from such Asset Sale are applied in accordance with paragraphs
                 (b) or (c) hereof.

                 (b)      The Company may apply such Net Available Proceeds
within 365 days after receipt of Net Available Proceeds from any Asset Sale,
to: (i) the repayment of Indebtedness of the Company under a Bank Credit
Facility or other Senior Indebtedness, including any mandatory redemption or
repurchase or optional redemption of the Existing Notes or the Securities; (ii)
make an Investment in assets used in the Oil and Gas Business; or (iii) develop
by drilling the Company's oil and gas reserves.

                 (c)      If, upon completion of the 365-day period referred to
above, any portion of the Net Available Proceeds of any Asset Sale shall not
have been applied by the Company as described in clauses (i), (ii) or (iii) of
the immediately preceding paragraph and such remaining Net Available Proceeds,
together with any remaining net cash proceeds from any prior Asset Sale (such
aggregate constituting "Excess Proceeds"), exceed $15,000,000, then the Company
will be obligated to make an offer (the "Net Proceeds Offer") to purchase the
Securities and any other Senior Indebtedness in respect of which such an offer
to purchase is required to be made concurrently with the Net Proceeds Offer
having an aggregate principal amount equal to the Excess Proceeds (such
purchase to be made on a pro rata basis if the amount available for such
repurchase is less than the principal amount of the Senior Notes and other
Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of
100% of the principal amount thereof plus accrued and unpaid interest on the
Securities and other Senior Indebtedness so repurchased to the date of
repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess
Proceeds will be reset to zero.

                 (d)      The Company shall commence a Net Proceeds Offer by
preparing and mailing a notice to the Trustee, the Paying Agent and each Holder
as of such record date as the Company shall establish (upon written notice to
the Trustee).  Notice of a Net Proceeds Offer to purchase the Securities will
be made on behalf of the Company not less than 25 Business Days nor more than
60 Business Days before the payment date of the Net Proceeds Offer (the "Net
Proceeds Payment Date"), and shall set forth the Net Proceeds Offer Amount and
the Net Proceeds Payment Date and refer to and summarize the material points
contained in Sections 4.11(d) and (e) hereof.  Securities tendered to the





                                      -29-
<PAGE>   36
Company pursuant to a Net Proceeds Offer will cease to accrue interest after
the Net Proceeds Payment Date.  For purposes of this covenant, the term "Net
Proceeds Offer Amount" means the principal of outstanding Securities in an
aggregate principal amount equal to any remaining Net Available Proceeds
(rounded to the next lowest $1,000).  If the Net Proceeds Payment Date is on or
after an interest payment record date and on or before the related interest
payment date, any accrued interest payable on such interest payment date will
be paid to the Person in whose name a Security is registered at the close of
business on such record date, and no additional interest will be payable to
Holders who tender Securities pursuant to the Net Proceeds Offer.

                 (e)      On the Net Proceeds Payment Date, the Company will
(i) accept for payment Securities and any other Senior Indebtedness in respect
of which such an offer to purchase is required to be made concurrently with the
Net Proceeds Offer  or portions thereof pursuant to the Net Proceeds Offer in
an aggregate principal amount equal to the Net Proceeds Offer Amount or such
lesser amount as has been tendered, (ii) deposit with the Paying Agent money
sufficient to pay the purchase price of all Securities and such other Senior
Indebtedness or portions thereof so tendered in an aggregate principal amount
equal to the Net Proceeds Offer Amount or such lesser amount, including any
accrued and unpaid interest thereon, and (iii) deliver or cause to be delivered
to the Trustee, Securities so accepted together with an Officers' Certificate
stating the Securities or portions thereof tendered to the Company.  If the
aggregate principal amount of Securities and such other Senior Indebtedness
tendered exceeds the Net Proceeds Offer Amount, the Trustee will select the
Securities and other Senior Indebtedness to be purchased (in integral multiples
of $1,000) on a pro rata basis based on the principal amount of Securities and
other Senior Indebtedness so tendered and notify the Company, the Registrar and
the Paying Agent.  The Paying Agent, upon instruction of the Company, will
promptly mail or deliver to Holders of Securities so accepted payment in an
amount equal to the purchase price (representing those funds received pursuant
to clause (ii) of this Section 4.11(e)), and the Company will execute and the
Trustee will promptly authenticate and mail or make available for delivery to
Holders a new Security equal in principal amount to any unpurchased portion of
the Security surrendered.  Any Securities not so accepted will be promptly
mailed or delivered to the Holder thereof by the Company, or, if the Company so
directs the Trustee, by the Trustee on behalf of the Company at the Company's
expense.  The Company will publicly announce the results of the Net Proceeds
Offer on or as soon as practicable after the Net Proceeds Payment Date.  For
purposes of this Section 4.11, the Trustee will act as the Paying Agent.

                 (f)      The Company will comply with Section 14 of the
Exchange Act and the provisions of Regulation 14E and any other tender offer
rules under the Exchange Act and any other federal and state securities laws,
rules and regulations which may then be applicable to any Net Proceeds Offer.

                 (g)      During the period between any Asset Sale and the
application of the Net Available Proceeds therefrom in accordance with this
covenant, all Net Available Proceeds shall be maintained in a segregated
account and shall be invested in Permitted Financial Investments.

                 (h)      Notwithstanding the foregoing, the Company will not
and will not permit any Restricted Subsidiary to, directly or indirectly, make
any Asset Sale of any of the Capital Stock of a Restricted Subsidiary except
pursuant to an Asset Sale of all of the Capital Stock of such Restricted
Subsidiary.

SECTION 4.12.    Limitation on Liens Securing Indebtedness.

                 The Company will not, and will not permit any of its
Restricted Subsidiaries to, create, incur, assume or suffer to exist any Liens
(other than Permitted Liens) upon any of their respective properties securing
(i) any Indebtedness of the Company, unless the Securities are equally and
ratably secured or (ii) any Indebtedness of any Restricted Subsidiary, unless
the Guarantees are equally and ratably secured; provided, that if such
Indebtedness is expressly subordinated to the Securities or the Guarantees, the
Lien securing such Indebtedness will be subordinated and junior to any Lien
securing the Securities or the Guarantees, with the same relative priority as
such Subordinated Indebtedness of the Company or Subordinated Indebtedness of a
Restricted Subsidiary will have with respect to the Securities or the
Guarantees, as the case may be.

SECTION 4.13.    Limitation on Sale/Leaseback Transactions.

                 The Company will not, and will not permit any of its
Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any
Person (other than the Company or any Wholly Owned Restricted Subsidiary)
unless (i) the Company or such Restricted Subsidiary, as the case may be, would
be able to incur Indebtedness in a principal amount equal to the Attributable
Indebtedness with respect to such Sale/Leaseback Transaction in accordance with
Section 4.09 or (ii) the Company or such Restricted Subsidiary receives
proceeds from such Sale/Leaseback Transaction at least equal to the fair market
value thereof (as determined in good faith by the Company's Board of Directors,
whose determination in good faith, evidenced by a resolution of such Board
shall be conclusive) and such proceeds are applied in the same manner and to
the same extent as Net Available Proceeds and Excess Proceeds from an Asset
Sale.

SECTION 4.14.    Limitation on Payment Restrictions Affecting Subsidiaries.

                 The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any consensual encumbrance or consensual
restriction on the ability of any Restricted Subsidiary of the Company to (i)
pay dividends or make any other distributions on its Capital Stock or on any
other interest or participation in the Company or a Restricted Subsidiary, (ii)
pay any Indebtedness owed to the Company or a Restricted Subsidiary of the
Company; (iii) make loans or advances to the Company or a Restricted Subsidiary
of the Company; or (iv) transfer any of its properties or assets to the Company
or a Restricted Subsidiary of the Company (each, a "Payment Restriction"),
except for (a) encumbrances or restrictions under a Bank Credit Facility;
provided, that any Payment Restrictions thereunder (other than, with respect to
(iv) above, customary restrictions in security agreements or other loan
documents thereunder securing or governing Indebtedness of a Restricted
Subsidiary) may be imposed only upon the acceleration of the maturity of the
Indebtedness thereunder; (b) consensual encumbrances or consensual restrictions
binding upon any Person at the time such Person becomes a Restricted Subsidiary
of the Company (unless the agreement creating such consensual encumbrances or
consensual restrictions was entered into in connection with, or in
contemplation of, such entity becoming a Restricted Subsidiary); (c) consensual
encumbrances or consensual restrictions under any agreement that refinances or
replaces any agreement described in clauses (a) and (b) above, provided that
the terms and conditions of any such restrictions are in the aggregate no less
favorable to the holders of the Securities than those under the agreement so
refinanced or replaced; and (d) customary non-assignment provisions in leases,
purchase money financings and any encumbrance or restriction due to applicable
law.

SECTION 4.15.    Limitation on Transactions with Affiliates.

                 The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, enter into any transaction
or series of transactions (including, without limitation, the sale, purchase or
lease of any assets or properties or the rendering of any services) with any
Affiliate or beneficial owner (as defined in Rules 13d-3 and 13d-5 under the
Exchange Act) of 10% or more of the Company's common stock (other than with a
Wholly Owned Restricted Subsidiary of the Company) (an "Affiliate
Transaction"), on terms that are less favorable to the Company or such
Restricted Subsidiary, as the case may be, than would be available in a
comparable transaction with an unrelated Person. In addition, the Company will
not, and will not permit any Restricted Subsidiary of the Company to, enter
into an Affiliate Transaction, or any series of related Affiliate Transactions
having a value of (a) more than $5,000,000 unless a majority of the Board of
Directors of the Company (including a majority of the Company's Disinterested
Directors) determines in good faith, as evidenced by a resolution of such
Board, that such Affiliate Transaction or series of related Affiliate
Transactions is fair to the Company; or (b) more than $25,000,000, unless the
Company receives a written opinion from a nationally recognized investment
banking firm with total assets in excess of $1.0 billion that such transaction
or series of transactions is fair to the Company from a financial point of
view.

SECTION 4.16.    Change of Control.

                 (a)      Following the occurrence of any Change of Control,
the Company shall offer (a "Change of Control Offer") to purchase all
outstanding Securities at a purchase price equal to 101% of the aggregate
outstanding principal amount of the Securities, plus accrued and unpaid
interest on the Securities so purchased to the date of purchase.  The Change of
Control Offer shall be deemed to have commenced upon mailing of the notice
described in the next succeeding paragraph and shall terminate 20 Business Days
after its commencement, unless a longer offering period is required by law.
Promptly after the termination of the Change of Control Offer (the "Change of
Control Payment Date"), the Company shall purchase and mail or deliver payment
for all Securities tendered in response to the Change of Control Offer.  If the
Change of Control Payment Date is on or after an interest payment record date
and on or before the related interest payment date, any accrued interest
payable on such interest payment date will be paid to the Person in whose name
a Security is registered at the close of business on such record date, and no
additional interest will be payable to Holders who tender Securities pursuant
to the Change of Control Offer.

                 (b)      Within 15 days after any Change of Control, the
Company (with notice to the Trustee and the Paying Agent), or the Trustee at
the Company's request and expense, will mail or cause to be mailed to all
Holders on the date of the Change of Control a notice prepared by the Company
(the "Change of Control Notice") of the occurrence of such Change of Control
and of the Holders' rights arising as a result thereof.  The Change of Control
Notice will contain all instructions and materials necessary to enable Holders
to tender their Securities to the Company.  The Change of Control Notice, which
shall govern the terms of the Change of Control Offer, shall state:  (1) that
the Change of Control Offer is being made pursuant to this Section 4.16; (2)
the purchase price and the Change of Control Payment Date; (3) that any
Security not tendered will continue to accrue interest at the stated rate; (4)
that any Security accepted for payment pursuant to the Change of Control Offer
shall cease to accrue interest on the Change of Control Payment Date; (5) that
Holders electing to have a Security purchased pursuant to any Change of Control
Offer will be required to surrender the Security, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Security completed,
to the Company, a depositary, if appointed by the Company, or a Paying Agent at
the address specified in the notice prior to termination of the Change of
Control Offer; (6) that Holders will be entitled to withdraw their election if
the Company, depositary or Paying Agent, as the case may be, receives, not
later than the expiration of the Change of Control Offer, or such longer period
as may be required by law, a telegram, telex, facsimile transmission or letter
setting forth the name of the Holder, the principal amount of the Security the
Holder delivered for purchase and a statement that such Holder is withdrawing
its election to have the Security purchased; and (7) that Holders whose
Securities are purchased only in part will be issued Securities equal in
principal amount to the unpurchased portion of the Securities surrendered.

                 (c)      On the Change of Control Payment Date, the Company
shall, to the extent permitted by applicable law, (i) accept for payment
Securities or portions thereof tendered pursuant to the Change of Control
Notice, (ii) if the Company appoints a depositary or Paying Agent, deposit with
such depositary or Paying Agent money sufficient to pay the purchase price of
all Securities or portions thereof so tendered and (iii) deliver to the Trustee
Securities so accepted together with an Officers' Certificate stating the
Securities or portions thereof tendered to the Company.  The depositary, the
Company or the Paying Agent, as the case may be, shall promptly mail to the
Holders of Securities so accepted payment in an amount equal to the purchase
price (representing those funds received pursuant to clause (ii) of this
Section 4.16(c)), and the Trustee shall promptly authenticate and mail to each
such Holder a new Security equal in principal amount to any unpurchased portion
of the Security surrendered; provided that each such new Security will be in a
principal amount of $1,000 or an integral multiple thereof.  The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.  For purposes of this
Section 4.16, the Trustee shall act as the Paying Agent.

                 (d)      The Company will comply with Section 14 of the
Exchange Act and the provisions of Regulation 14E and any other tender offer
rules under the Exchange Act and any other federal and state securities laws,
rules and regulations which may then be applicable to any offer by the Company
to purchase the Securities at the option of the Holders upon a Change of
Control.

transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under this Indenture with the same effect

                 individually or, taken together with the principal amount of

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

                 The term "Bankruptcy Law" means Title 11, U.S. Code or any

SECTION 6.02.    Acceleration.

                 If an Event of Default (other than an Event of Default
specified in clauses (8) or (9)) under Section 6.01 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 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 6.03.    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 6.01 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

<PAGE>   42
remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default.  No remedy
is exclusive of any other remedy.  All available remedies are cumulative.

SECTION 6.04.    Waiver of Past Defaults.

                 Subject to Sections 6.07 and 9.02, 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 6.05.    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 6.06.    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 6.07.    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 6.08.    Collection Suit by Trustee.

                 If an Event of Default in payment of principal, premium, if
any, or interest specified in Section 6.01(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 of collection,
including the reasonable compensation and expenses of the Trustee, its agents
and counsel.

SECTION 6.09.    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 
                 7.07;

                          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 6.07, or a suit by Holders of more than 10% in
principal amount of the then outstanding Securities.

                                    TRUSTEE

SECTION 7.01.    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.

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

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

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

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

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

                          (2)     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.

                          (3)     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
                 6.05, and the Trustee shall be entitled from time to time to
                 request such a direction.

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

                 (e)      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 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.

                 (f)      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 7.02.    Rights of Trustee.

                 Subject to Section 7.01:

                 (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.



                                      -38-
<PAGE>   45
                 (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 7.03.    Individual Rights of Trustee.

                 The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company or
its 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 7.04.    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 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 7.05.    Notice of Defaults.

                 If a Default occurs and is continuing and if it is known to
the Trustee, the Trustee shall mail to each Holder pursuant to Section 11.02 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 7.06.    Reports by Trustee to Holders.

                 Within 60 days after each April 1, beginning with the April 1
following the date of this Indenture, the Trustee shall mail to each Holder a
brief report dated as of such April 1 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 7.07.    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





                                      -39-
<PAGE>   46
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 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
7.07) 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 7.07 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 6.01(8) or (9), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law.

SECTION 7.08.    Replacement of Trustee.

                 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:

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

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

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

                          (4)     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 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 7.07, 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.

<PAGE>   47
                 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 7.09.    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.

SECTION 8.01.    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 8.02 or 8.03 with respect to all outstanding Securities upon compliance
with the conditions set forth below in this Article Eight.

SECTION 8.02.    Legal Defeasance and Discharge.

                 Upon the Company's exercise under Section 8.01 of the option
applicable to this Section 8.02, the Company shall be deemed to have been
discharged from its 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 8.05 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 8.04, 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 2.03, 2.04, 2.06, 2.07, 2.10 and 4.04, (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
7.07) and (d) this Article Eight.  Subject to compliance with this Article
Eight, the Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 with
respect to the Securities.

SECTION 8.03.    Covenant Defeasance.

                 Upon the Company's exercise under Section  8.01 of the option
applicable to this Section 8.03, the Company shall be released from its
obligations under the covenants contained in the second sentence of Section
4.02, Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, and
4.16 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 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 6.01(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 8.01 of the
option applicable to this Section 8.03, Sections 6.01(4) through 6.01(9) shall
not constitute Events of Default.

SECTION 8.04.    Conditions to Legal or Covenant Defeasance.

                 The following shall be the conditions to application of either
Section 8.02 or Section 8.03 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 U.S. Government Securities to said payments with respect to the
Securities.

                 (b)      In the case of an election under Section 8.02, 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;

                 (c)      In the case of an election under Section 8.03, 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 6.01(8) or 6.01(9) is concerned, at any time in the
period





                                      -42-

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 8.02 or
8.03, 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 8.02 or 8.03 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 8.02 or the Covenant Defeasance under Section 8.03 (as the case may be)
have been complied with as contemplated by this Section 8.04.

SECTION 8.05.    Deposited Money and U.S. Government Securities to be Held in
Trust; Other Miscellaneous Provisions.

                 Subject to Section 8.06, 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
8.05, the "Trustee") pursuant to Section 8.04 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 8.04 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.

                 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 8.04 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 8.04(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 8.06.    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 8.05 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.

<PAGE>   50
SECTION 8.07.    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 8.02 or 8.03, 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 8.02 or 8.03 until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 8.02 or 8.03, 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 NINE

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.    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 5.01;

                          (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 9.06, 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 9.02.    With Consent of Holders.

                 Except as provided below in this Section 9.02, 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.

                 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





                                      -44-
<PAGE>   51
Opinion of Counsel described in Section 9.06, 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)     reduce the repurchase price, including
                 premium, if any, payable upon the repurchase of any Security
                 pursuant to Sections 4.11 or 4.16, or change the time at which
                 any Security may or shall be repurchased thereunder;

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

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

                          (8)     impair the right to institute suit for the
                 enforcement of principal of, premium, if any, or principal on
                 any Security pursuant to Sections 6.07 or 6.08, except as
                 limited by Section 6.06; or

                          (9)     make any change in Section 6.04 or Section
                 6.07 or in this sentence of this Section 9.02.

                 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 9.03.    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.





                                      -45-
<PAGE>   52
SECTION 9.04.    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
2.05, 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
(1) through (9) of Section 9.02.  In that case the amendment, supplement or
waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the
same debt as the consenting Holder's Security.

SECTION 9.05.    Notation on or Exchange of Senior Notes.

                 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 9.06.    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 TEN

                                   GUARANTEES

SECTION 10.01.   Unconditional Guarantee.

                 Each Subsidiary Guarantor hereby, jointly and severally, fully
and unconditionally guarantees, as principal obligor and not only as surety
(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,





                                      -46-
<PAGE>   53
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 10.05.

                 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 10.02.   Subsidiary Guarantors May Consolidate, etc., on Certain Terms.

                 (a)      Subject to paragraph (b) of this Section 10.02, 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, (ii) immediately after such transaction, no
Default or Event of Default exists, (iii) such Subsidiary Guarantor or the
entity or Person formed by or surviving any such consolidation or merger will
have Consolidated Tangible Net Worth (immediately after the transaction) equal
to or greater than the Consolidated Tangible Net Worth of such Subsidiary
Guarantor immediately preceding the transaction and (iv) the Company will, at
the time of such transaction after giving pro forma effect thereto as if such
transaction had occurred at the beginning of the applicable Reference Period,
be permitted to incur at least $1.00 of additional Indebtedness pursuant to
Section 4.09(a).  In connection with any consolidation or merger contemplated
by this Section 10.02, 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 10.02(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; provided that in the event such sale or disposition constitutes an
Asset Sale, the Net Available Proceeds of such sale or other disposition are
applied in accordance with the provisions of this Indenture described under
Section 4.11.





                                      -47-
<PAGE>   54
SECTION 10.03.   Addition of Subsidiary Guarantors.

                 (a)      The Company agrees to cause each 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.

                 (b)      Any Person that was not a Subsidiary Guarantor on the
Issue Date may become a Subsidiary 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 and binding 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 10.04.   Release of a Subsidiary Guarantor.

                 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
10.02, such Subsidiary Guarantor shall be deemed released from all of its
Guarantee and related obligations in this Indenture.  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 was made by the Company in
accordance with the provisions of this Indenture.  Any Subsidiary Guarantor not
so released remains liable for the full amount of principal of and interest on
the Securities as provided in this Article Ten.

SECTION 10.05.   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, state or
foreign 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 10.06, result in the obligations of such Subsidiary
Guarantor under the Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal, state or foreign law.  This Section 10.05 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 10.06.   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

SECTION 10.07.   Execution and Delivery of Guarantee.

                 To further evidence the Guarantees set forth in Section 10.01,

                 Each of the Subsidiary Guarantors hereby agrees that its
Guarantee set forth in Section 10.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation relating to
such Guarantee.

                 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.

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

SECTION 10.08.   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.

                             [REVERSE OF SECURITY]

                         CHESAPEAKE ENERGY CORPORATION

                    9 5/8% SERIES [A/B] SENIOR NOTE DUE 2005

                 1.       Interest.  Chesapeake Energy Corporation, an Oklahoma
corporation (the "Company"), promises to pay interest on the principal amount
of this Security at 9 5/8% per annum from the Issue Date until maturity.  The
Company will pay interest semiannually on May 1 and November 1 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 November  1, 1998.  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 such amounts by check payable
in such money.  It may mail an interest check to a 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 specified by the
Holders of such Securities or, if no such account is specified, by check to
each such Holder's address.  If this Security is a Global Security, all
payments in respect of this Security will be made to the Depositary or its
nominee by wire transfer of immediately available funds to the account(s)
specified by the Depositary or its nominee and in accordance with customary
procedures established from time to time by the Depositary.

                 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 April 1,  1998 (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 $500,000,000
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.

principal amount of the Securities with all or a portion of the aggregate net
proceeds received by the Company from any such Equity Offering or Equity
Offerings at a redemption price of 109.625% of the aggregate principal amount
of Securities so redeemed, plus accrued and unpaid interest on the Securities
so redeemed to the redemption date; provided, however, that (i) the date of any
such redemption occurs within the 90-day period after the Equity Offering in
respect of which such redemption is made and (ii) following each such
redemption, at least $333,000,000 of the aggregate principal amount of the
Securities remains outstanding.  Any redemption pursuant to this Paragraph 7
shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the
Indenture.

                 8.     Redemption at Make-Whole Price.  At any time prior to
May 1, 2002, the Company may, at its option, redeem all or any portion of the
Securities at the Make-Whole Price plus accrued and unpaid interest on the
Securities so redeemed to the date of redemption.  Any redemption pursuant to
this Paragraph 8 shall be made pursuant to the provisions of Sections 3.01
through 3.06 of the Indenture.

                 9.     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).

                 10.    Change of Control Offer.  In the event of a Change of
Control of the Company, the Company shall be required to make an offer to
purchase all or any portion of each Holder's Securities, at 101% of the
principal amount thereof, plus accrued and unpaid interest to the date of
purchase.

                 11.    Net Proceeds Offer.  In the event of certain Asset
Sales (and Sale/Leaseback Transactions), the Company may be required to make a

the Net Proceeds Payment Date.

                 12.    Restrictive Covenants.  The Indenture imposes certain

                                      A-4
<PAGE>   65
certain property and to enter into certain transactions with Affiliates, all
subject to certain limitations described in the Indenture.

                 13.    Denominations, Transfer, Exchange.  The Securities
shall be issued in global form or in accordance with Section 2.06(f) of the
Indenture, in definitive 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.

                 14.    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.

                 15.    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.

                 16.    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.

                 17.    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.

                 18.    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;
failure by the Company to make any offer to purchase; 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.

                 19.    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.

<PAGE>   66
                 20.    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.

                 21.    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.

Restricted Securities shall be entitled to liquidated damages pursuant to
Section 4 hereof unless such Holder shall have timely provided all such
information.  Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information
previously furnished to the Company by such Holder not materially misleading.

SECTION 4.          LIQUIDATED DAMAGES

          If the Shelf Registration Statement (i) is not filed with the
Commission on or prior to the Filing Deadline, (ii) has not been declared
effective by the Commission on or prior to the Effectiveness Deadline, or (iii)
is filed and declared effective but shall thereafter cease to be effective or
fail to be usable for its intended purpose (other than as a result of





                                      -3-

a Suspension Notice) without being succeeded (a) within five Business Days by a
post-effective amendment to such Shelf Registration Statement or a supplement
to the Prospectus under Rule 424 of the Act or that cures such failure and that
is itself declared effective within ten days of filing such post-effective
amendment to the Shelf Registration Statement or (b) within 20 days by the
filing of an Exchange Act report incorporated by reference in such Shelf
Registration Statement that cures such failure (each such event referred to in
clauses (i) through (iii), a "REGISTRATION DEFAULT"), then the Company hereby
agrees to pay to each Holder of Transfer Restricted Securities affected thereby
liquidated damages in an amount equal to one-half of one percent (0.5%) per
annum of the liquidation preference amount of the Transfer Restricted
Securities held by such holder during the first 90-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 liquidation
preference amount of such Transfer Restricted Securities during each subsequent
90-day period, up to a maximum amount of liquidated damages equal to two
percent (2.0%) per annum of the liquidation preference of such Transfer
Restricted Securities, which provision for liquidated damages will continue
until such Registration Default has been cured; provided that the Company shall
in no event be required to pay liquidated damages for more than one
Registration Default at any given time.  Notwithstanding anything to the
contrary set forth herein, (1) upon filing of the Shelf Registration Statement,
in the case of (i) above, (2) upon the effectiveness of the Shelf Registration
Statement, in the case of (ii) above, or (3) upon the filing of a (a)
post-effective amendment to the Shelf Registration Statement or a Prospectus
supplement or (b) an Exchange Act report that causes the Shelf Registration
Statement to again be declared effective or made usable, in the case of (iii)
above, the liquidated damages payable with respect to the Transfer Restricted
Securities as a result of such clause (i), (ii) or (iii), as applicable, shall
cease.

          All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of dividends, on each Dividend
Payment Date as more fully set forth in the Certificate of Designation.
Notwithstanding the fact that any Shares and/or shares of Common Stock for
which liquidated damages are due cease to be Transfer Restricted Securities,
all obligations of the Company to pay liquidated damages with respect to any
such Shares and/or shares of Common Stock shall survive until such time as all
such obligations shall have been satisfied in full.

SECTION 5.          SHELF REGISTRATION PROCEDURES

          (a)  Procedures.  In connection with the Shelf Registration
Statement, the Company shall:

               (i)  use its best efforts to effect such registration to permit
               the sale of the Transfer Restricted Securities being sold in
               accordance with the intended method or methods of distribution
               thereof (as indicated in the information furnished to the
               Company pursuant to Section 3(b) hereof), and pursuant thereto
               the Company will prepare and file with the Commission a Shelf
               Registration Statement relating to the registration on any
               appropriate form under the Act, which form shall be available
               for the sale of the Transfer Restricted Securities in accordance
               with the intended method or methods of distribution thereof
               (including, without limitation, one or more underwritten
               offerings) within the time periods and otherwise in accordance
               with the provisions hereof.  The Company shall not be permitted
               to include in the Shelf Registration Statement any securities
               other than the Transfer Restricted Securities;

               (ii)  use its best efforts to contact all Holders of Transfer
               Restricted Securities and notify each Holder of its right to
               include its Transfer Restricted Securities in such Shelf
               Registration Statement;

               (iii)  use its best efforts to keep such Shelf Registration
               Statement continuously effective and provide all requisite
               financial statements for the period specified in Section 3 of
               this Agreement.  Upon the occurrence of any event that would
               cause any such Shelf Registration Statement or the Prospectus
               contained therein (i) to contain an untrue statement of a
               material fact or omit to state any material fact necessary to
               make the statements therein not misleading or (ii) not to be
               effective and usable for resale of Transfer Restricted
               Securities during the period required by this Agreement, the
               Company shall file promptly (A) an appropriate amendment to such
               Shelf Registration Statement curing such defect, and, if
               Commission review is required, use its best efforts to cause
               such amendment to be declared effective as soon as practicable,
               (B) a supplement pursuant to Rule 424 under the Act curing such
               defect or (C) an Exchange Act report incorporated by reference
               curing such defect;





                                      -4-

               (iv)  prepare and file with the Commission such amendments and
               post-effective amendments to the Shelf Registration Statement as
               may be necessary to keep such Shelf Registration Statement
               effective for the applicable period set forth in Section 3
               hereof, cause the Prospectus to be supplemented by any required
               Prospectus supplement, and as so supplemented to be filed
               pursuant to Rule 424 under the Act, and to comply fully with
               Rules 424, 430A and 462, as applicable, under the Act in a
               timely manner; and comply with the provisions of the Act with
               respect to the disposition of all Transfer Restricted Securities
               covered by such Shelf Registration Statement during the
               applicable period in accordance with the intended method or
               methods of distribution by the sellers thereof set forth in such
               Shelf Registration Statement or supplement to the Prospectus;

               (v)  advise the Holders and underwriters, if any, promptly and,
               if requested by such Persons, confirm such advice in writing,
               (A) when the Shelf Registration Statement or any Prospectus
               supplement or post- effective amendment has been filed, and,
               with respect to the Shelf Registration Statement or any post-
               effective amendment thereto, when the same has become effective,
               (B) of any request by the Commission for amendments to the Shelf
               Registration Statement or amendments or supplements to the
               Prospectus or for additional information relating thereto, (C)
               of the issuance by the Commission of any stop order suspending
               the effectiveness of the Shelf Registration Statement under the
               Act or of the suspension by any state securities commission of
               the qualification of the Transfer Restricted Securities for
               offering or sale in any jurisdiction, or the initiation of any
               proceeding for any of the preceding purposes, (D) of the
               existence of any fact or the happening of any event that makes
               any statement of a material fact made in the Shelf Registration
               Statement, the Prospectus, any amendment or supplement thereto
               or any document incorporated by reference therein untrue, or
               that requires the making of any additions to or changes in the
               Shelf Registration Statement in order to make the statements
               therein not misleading, or that requires the making of any
               additions to or changes in the Prospectus in order to make the
               statements therein, in the light of the circumstances under
               which they were made, not misleading.  If at any time the
               Commission shall issue any stop order suspending the
               effectiveness of the Shelf Registration Statement, or any state
               securities commission or other regulatory authority shall issue
               an order suspending the qualification or exemption from
               qualification of the Transfer Restricted Securities under state
               securities or Blue Sky laws, the Company shall use its best
               efforts to obtain the withdrawal or lifting of such order at the
               earliest possible time;

               (vi)  subject to Section 5(a)(iii), if any fact or event
               contemplated by Section 5(a)(v)(D) above shall exist or have
               occurred, prepare a post-effective amendment or supplement to
               the Shelf Registration Statement or related Prospectus or any
               document incorporated therein by reference or file any other
               required document so that, as thereafter delivered to the
               purchasers of Transfer Restricted Securities, 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, in the light of the circumstances under which they were
               made, not misleading;

               (vii)  upon the request of counsel for the Holders and
               underwriters, if any, furnish to such counsel before filing with
               the Commission, copies of any Shelf Registration Statement or
               any Prospectus included therein or any amendments or supplements
               to any such Shelf Registration Statement or Prospectus
               (including all documents incorporated by reference after the
               initial filing of such Shelf Registration Statement), which
               documents will be subject to the review and comment of such
               counsel in connection with such sale, if any, for a period of at
               least five Business Days, and the Company will not file any such
               Shelf Registration Statement or Prospectus or any amendment or
               supplement to any such Shelf Registration Statement or
               Prospectus (including all such documents incorporated by
               reference) to which such Persons shall reasonably object within
               five Business Days after the receipt thereof.  Any such Person
               shall be deemed to have reasonably objected to such filing if
               such Registration Statement, amendment, Prospectus or
               supplement, as applicable, as proposed to be filed, contains an
               untrue statement of a material fact or omits to state any
               material fact necessary to make the statements therein not
               misleading or fails to comply with the applicable requirements
               of the Act;

               (viii)  upon the request of any Holder or underwriter, if any,
               provide copies of any document filed with the Commission that is
               incorporated by reference into the Shelf Registration Statement
               or Prospectus

               to such Holder or underwriter, and make the Company's
               representatives available for discussion of such document and
               other customary due diligence matters;

               (ix)  make available at reasonable times for inspection by the
               Holders and underwriters, if any, and any attorney or accountant
               retained by such Holders or underwriters, if any, all financial
               and other records, pertinent corporate documents of the Company
               and cause the Company's officers and employees to supply all
               information reasonably requested by any such Holder,
               underwriters, attorney or accountant in connection with the
               Shelf Registration Statement or any post-effective amendment
               thereto subsequent to the filing thereof and prior to its
               effectiveness;

               (x)  if requested by any Holder or underwriter, if any, promptly
               include in the Shelf Registration Statement or Prospectus,
               pursuant to a supplement or post-effective amendment, if
               necessary, such information as such Holder or underwriter may
               reasonably request to have included therein, including, without
               limitation, information relating to the "Plan of Distribution"
               of the Transfer Restricted Securities; and make all required
               filings of such Prospectus supplement or post-effective
               amendment as soon as practicable after the Company is notified
               of the matters to be included in such Prospectus supplement or
               post-effective amendment;

               (xi)  upon the request of any Holder or underwriter, if any,
               furnish such Holder or underwriter, if any, without charge, at
               least one copy of the Shelf Registration Statement, as first
               filed with the Commission, and of each amendment thereto;

               (xii)  deliver to each Holder and underwriter, if any, without
               charge, as many copies of the Prospectus (including each
               preliminary prospectus) and any amendment or supplement thereto
               as such Holder or underwriter reasonably may request; the
               Company hereby consents to the use (in accordance with law) of
               the Prospectus and any amendment or supplement thereto by each
               Holder and each underwriter, if any, in connection with the
               offering and the sale of the Transfer Restricted Securities
               covered by the Prospectus or any amendment or supplement
               thereto;

               (xiii)  upon the request of any Holder or underwriter, if any,
               enter into such agreements (including underwriting agreements)
               and make such representations and warranties and take all such
               other actions in connection therewith in order to expedite or
               facilitate the disposition of the Transfer Restricted Securities
               pursuant to the Shelf Registration Statement as may be
               reasonably requested by such Holder or underwriter in connection
               with any sale or resale pursuant to the Shelf Registration
               Statement and in such connection, the Company shall:

                     (A)  upon request of any such Holder or underwriter
               furnish (or in the case of paragraphs (2) and (3) below, use its
               best efforts to cause to be furnished) to each Holder or
               underwriter upon the effectiveness of the Shelf Registration
               Statement:

                     (1)  a certificate, dated such date, signed on behalf of
               the Company by the Chairman of the Board or President and
               Financial Officer of the Company, confirming, as of the date
               thereof, the matters set forth in Sections 6(v), 9(a) and 9(b)
               of the Purchase Agreement and such other similar matters as such
               Person may reasonably request;

                    (2)  an opinion, dated the date of effectiveness of the
               Shelf Registration Statement, of counsel for the Company
               covering matters similar to those set forth in paragraph (e) of
               Section 9 of the Purchase Agreement and such other matter as
               such Holder or underwriter may reasonably request, and in any
               event including a statement to the effect that such counsel has
               participated in conferences with officers and other
               representatives of the Company, representatives of the
               independent public accountants for the Company and has
               considered the matters required to be stated therein and the
               statements contained therein, although such counsel has not
               independently verified the accuracy, completeness or fairness of
               such statements; and that such counsel advises that, on the
               basis of the foregoing (relying as to materiality to the extent
               such counsel deems appropriate upon the statements of officers
               and other representatives of the Company and without independent
               check or verification), no facts came to such counsel's
               attention that caused such counsel to believe that the Shelf
               Registration Statement and any





                                      -6-
<PAGE>   7




               post-effective amendment thereto, at the time such Shelf
               Registration Statement or any post-effective amendment thereto
               became effective, contained an untrue statement of a material
               fact or omitted to state a material fact required to be stated
               therein or necessary to make the statements therein, in the
               light of the circumstances under which they were made, not
               misleading, or that the Prospectus contained in such Shelf
               Registration Statement, as of its date, contained an untrue
               statement of a material fact or omitted to state a material fact
               necessary in order to make the statements therein, in the light
               of the circumstances under which they were made, not misleading.
               Without limiting the foregoing, such counsel may state further
               that such counsel assumes no responsibility for, and has not
               independently verified the accuracy, completeness or fairness of
               the financial statements, notes and schedules and other
               financial data included in the Shelf Registration Statement or
               the related Prospectus; and

                    (3)  a customary comfort letter, dated as of the date of
               effectiveness of the Shelf Registration Statement from the
               Company's independent accountants, in the customary form and
               covering matters of the type customarily covered in comfort
               letters to underwriters in connection with underwritten
               offerings, and affirming the matters set forth in the comfort
               letters delivered pursuant to Section 9(i) of the Purchase
               Agreement; and

                    (B)  deliver such other documents and certificates as may
               be reasonably requested by such Holder or underwriter to
               evidence compliance with the matters set forth in clause (A)
               above and with any customary conditions contained in any
               agreement entered into by the Company pursuant to this clause
               (xiii);

               (xiv)  prior to any public offering of Transfer Restricted
               Securities, cooperate with the Holders, underwriters, if any,
               and their respective counsel in connection with the registration
               and qualification of the Transfer Restricted Securities under
               the securities or Blue Sky laws of such jurisdictions as such
               Persons may request and do any and all other acts or things
               necessary or advisable to enable the disposition in such
               jurisdictions of the Transfer Restricted Securities covered by
               the Shelf Registration Statement; provided, however, that the
               Company shall not be required to register or qualify as a
               foreign corporation where it is not now so qualified or to take
               any action that would subject it to the service of process in
               suits or to taxation, other than as to matters and transactions
               relating to the Shelf Registration Statement, in any
               jurisdiction where it is not now so subject;

               (xv)  in connection with any sale of Transfer Restricted
               Securities that will result in such securities no longer being
               Transfer Restricted Securities, cooperate with the Holders to
               facilitate the timely preparation and delivery of certificates
               (including global certificates registered in the name of Cede &
               Co. as nominee for The Depository Trust Company) representing
               Transfer Restricted Securities to be sold and not bearing any
               restrictive legends; and, in the case of certificated Transfer
               Restricted Securities, to register such Transfer Restricted
               Securities in such denominations and such names as the Holders
               may request at least two Business Days prior to such sale of
               Transfer Restricted Securities;

               (xvi)  list all shares of Common Stock covered by the Shelf
               Registration Statement on any securities exchange on which the
               Common Stock is then listed;

               (xvii)  use its best efforts to cause the disposition of the
               Transfer Restricted Securities covered by the Shelf Registration
               Statement to be registered with or approved by such other
               governmental agencies or authorities as may be required to
               enable the seller or sellers thereof to consummate the
               disposition of such Transfer Restricted Securities, subject to
               the provision contained in clause (xiv) above;

               (xviii)  otherwise use its best efforts to comply with all
               applicable rules and regulations of the Commission, and make
               generally available to its security holders with regard to the
               Shelf Registration Statement, as soon as practicable, a
               consolidated earnings statement meeting the requirements of Rule
               158 (which need not be audited) covering a twelve-month period
               beginning after the effective date of the Shelf Registration
               Statement (as such term is defined in paragraph (c) of Rule 158
               under the Act);

               (xix)  if underwritten, make appropriate officers of the Company
               available to the underwriters for meetings with prospective
               purchasers of the Transfer Restricted Securities and prepare and

               potential investors customary "road show" material in a manner
               consistent with other new issuances of other securities similar
               to the Transfer Restricted Securities; and

          (b)  Restrictions on Holders.  Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of (i) the notice referred to
in Section 5(a)(v)(C), (ii) any notice from the Company of the existence of any
fact of the kind described in Section 5(a)(v)(D) hereof or (iii) any notice
from the Company that (a) sales under any Registration Statement contemplated
by this Agreement would require the disclosure of material information which
the Company has a bona fide business purpose for preserving as confidential, or
(b) such disclosure would impede the Company's ability to consummate a material
transaction (in each case, a "SUSPENSION NOTICE"), such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the
applicable Registration Statement until (A) such Holder has received copies of
the supplemented or amended Prospectus contemplated by Section 5(a)(vi) hereof,
or (B) such Holder is advised in writing by the Company that the use of the
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus (in
each case, the "RECOMMENCEMENT DATE"), provided, that any suspension pursuant
to clause (iii) above shall not exceed 60 days in any twelve-month period.
Each Holder receiving a Suspension Notice hereby agrees that it will either (x)
destroy any Prospectuses, other than permanent file copies, then in such
Holder's possession which have been replaced by the Company with more recently
dated Prospectuses or (y) deliver to the Company (at the Company's expense) all
copies, other than permanent file copies, then in such Holder's possession of
the Prospectus covering such Transfer Restricted Securities that was current at
the time of receipt of the Suspension Notice.  The time period regarding the
effectiveness of the Shelf Registration Statement set forth in Section 3 hereof
shall be extended by a number of days equal to the number of days in the period
from and including the date of delivery of the Suspension Notice to the date of
delivery of the Recommencement Date.

SECTION 6.          REGISTRATION EXPENSES

          (a)  All expenses incident to the Company's performance of or
compliance with this Agreement will be borne by the Company, regardless of
whether a Shelf Registration Statement required by this Agreement becomes
effective, including without limitation: (i) all registration and filing fees
and expenses; (ii) all fees and expenses of compliance with federal securities
and state Blue Sky or securities laws; (iii) all expenses of printing
(including printing certificates for the Common Stock to be issued upon
conversion of the Shares and printing of Prospectuses), messenger and delivery
services and telephone; (iv) all fees and disbursements of counsel for the
Company and not more than one counsel for the Holders of Transfer Restricted
Securities as described in Section 6(b) below; (v) all application and filing
fees in connection with listing the Common Stock on a national securities
exchange pursuant to the requirements hereof; and (vi) all fees and
disbursements of independent certified public accountants of the Company
(including the expenses of any special audit and comfort letters required by or
incident to such performance).

          The Company will, in any event, bear its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expenses of any annual
audit and the fees and expenses of any Person, including special experts,
retained by the Company.

          (b)  In connection with the Shelf Registration Statement required by
this Agreement, the Company will reimburse the Initial Purchasers and the
Holders selling Transfer Restricted Securities pursuant to the "Plan of
Distribution" contained in the Shelf Registration Statement, for the reasonable
fees and disbursements of not more than one counsel, who shall be Andrews &
Kurth L.L.P., unless another firm shall be chosen by the Holders of a majority

SECTION 7.          INDEMNIFICATION

          (a)  The Company agrees to indemnify and hold harmless each Holder,
its directors, its officers and each Person, if any, who controls such Holder
(within the meaning of Section 15 of the Act and Section 20 of the Exchange
Act), from and against any and all losses, claims, damages, liabilities,
judgments, (including without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Shelf Registration Statement, preliminary
prospectus or Prospectus (or any amendment or supplement thereto) provided by
the Company to any Holder or any prospective purchaser of registered Shares or
registered shares of Common Stock 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 not misleading, except insofar as such losses,
claims, damages, liabilities or judgments are caused by an untrue statement or
omission or alleged untrue statement or omission that is based upon information
relating to any of the Holders furnished in writing to the Company by any of
the Holders.

          (b)  Each Holder of Transfer Restricted Securities agrees, severally
and not jointly, to indemnify and hold harmless the Company and its directors
and officers, and each person, if any, who controls (within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act) the Company, to the
same extent as the foregoing indemnity from the Company set forth in section
(a) above, but only with reference to information relating to such Holder
furnished in writing to the Company by such Holder expressly for use in the
Shelf Registration Statement.  In no event shall any Holder, its directors, its
officers or any Person, if any, who controls such Holder be liable or
responsible for any amount in excess of the amount by which the total amount
received by such Holder with respect to its sale of Transfer Restricted
Securities pursuant to the Shelf Registration Statement exceeds (i) the amount
paid by such Holder for such Transfer Restricted Securities and (ii) the amount
of any damages that such Holder, its directors, its officers or any Person, if
any, who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

          (c)  In case any action shall be commenced involving any Person in
respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the Person
against whom such indemnity may be sought (the "INDEMNIFYING PERSON") in
writing and the indemnifying party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel, as incurred
(except that in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 7(a) and 7(b), a Holder shall not be required
to assume the defense of such action pursuant to this Section 7(c), but may
employ separate counsel and participate in the defense thereof, but the fees
and expenses of such counsel, except as provided below, shall be at the expense
of the Holder).  Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) for all indemnified parties and all such
fees and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by a majority of the Holders, in the case of the parties
indemnified pursuant to Section 7(a), and by the Company, in the case of
parties indemnified pursuant to Section 7(b).  The indemnifying party shall
indemnify and hold harmless the indemnified party from and against any and all
losses, claims, damages, liabilities and judgments by reason of any settlement
of any action (i) effected with its written consent or (ii) effected without
its written consent if the settlement is entered into more than twenty business
days after the indemnifying party shall have received a request from the
indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and, prior to the date of such settlement, the indemnifying party shall
have failed to comply with such reimbursement request.   No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement or compromise of, or consent to the entry of judgment with





                                      -9-
<PAGE>   10




respect to, any pending or threatened action in respect of which the
indemnified party is or could have been a party and indemnity or contribution
may be or could have been sought hereunder by the indemnified party, unless
such settlement, compromise or judgment (i) includes an unconditional release
of the indemnified party from all liability on claims that are or could have
been the subject matter of such action and (ii) does not include a statement as
to or an admission of fault, culpability or a failure to act, by or on behalf
of the indemnified party.

          (d)  To the extent that the indemnification provided for in this
Section 7 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
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 (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Holders, on the other hand, from their sale
of Transfer Restricted Securities or (ii) if the allocation provided by clause
7(d)(i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
7(d)(i) above but also the relative fault of the Company on the one hand, and
of the Holders, on the other hand, 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, on the one hand, and of the Holders, on the
other hand, 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, on the one hand, or by the Holders, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and judgments
referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 6(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 and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any
matter, including any action that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 7, no Holder or its related Indemnified Holders shall be required to
contribute, in the aggregate, any amount in excess of the amount by which the
total received by such Holder with respect to the sale of its Transfer
Restricted Securities pursuant to the Shelf Registration Statement exceeds (i)
the amount paid by such Holder for such Transfer Restricted Securities and (ii)
the amount of any damages which such Holder has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The Holders'
obligations to contribute pursuant to this Section 7(d) are several in
proportion to the respective liquidation  preference of Transfer Restricted
Securities held by each of the Holders hereunder and not joint.


SECTION 8.          RULE 144A AND RULE 144

          The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder of Transfer Restricted Securities, to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of Transfer Restricted
Securities designated by such Holder or beneficial owner, the information
required by Rule 144(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to
Section 13 or 15(d) of the Exchange Act, to make all filings required thereby
in a timely manner in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144 (if available).

SECTION  9.         UNDERWRITTEN REGISTRATIONS

          (a)  If any of the Transfer Restricted Securities covered by the
Shelf Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
liquidation preference of such Transfer Restricted Securities included in such
offering, subject to the consent of the Company (which will not be unreasonably
withheld or delayed); provided, that any such underwritten offering shall
include a minimum of $50,000,000 in aggregate liquidation preference of
Transfer Restricted Securities.

          No Holder of Transfer Restricted Securities may participate in any
underwritten registration hereunder unless such Holder (i) agrees to sell its
Transfer Restricted Securities on the basis reasonably provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

          (b)  Each Holder of Transfer Restricted Securities agrees, if
requested (pursuant to a timely written notice) by the managing underwriters in
an underwritten offering made pursuant to the Shelf Registration Statement, not
to effect any private sale or distribution (including a sale pursuant to Rule
144(k) and Rule 144A, but excluding non- public sales to any of its affiliates,
officers, directors, employees and controlling persons) of any of the Shares,
in the case of an underwritten offering of the Shares, or the Common Stock, in
the case of an underwritten offering of shares of Common Stock constituting
Transfer Restricted Securities, during the period beginning 10 days prior to,
and ending 90 days after, the closing date of such underwritten offering.

          The foregoing provisions of Section 9(b) shall not apply to any
Holder of Transfer Restricted Securities if such Holder is prevented by
applicable statute or regulation from entering into any such agreement.

          (c)  If any of the Transfer Restricted Securities covered by any
Shelf Registration are to be sold in an underwritten offering, the
underwriters, their controlling persons and their respective officers,
directors, employees, representatives and agents shall be entitled to indemnity
(substantially similar to the indemnity set forth in Section 7 of this
Agreement) from the Company and the Holders, which indemnity may be set forth
in an underwriting agreement.

SECTION 10.         MISCELLANEOUS

          (a)  Remedies.  The Company acknowledges and agrees that any failure
by the Company to comply with its obligations under Section 3 hereof may result
in material irreparable injury to the Initial Purchasers or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's  obligations under Section 3
hereof.  The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

          (b)  No Inconsistent Agreements.  The Company will not, on or after
the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof.  The Company has
not previously entered into any agreement (which has not expired or been
terminated) granting any registration rights with respect to its securities to
any Person, except as disclosed in the Purchase Agreement.  The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof.

          (c)  No Piggybacks on Shelf Registration Statement.  The Company
shall not grant to any of its security holders (other than the holders of
Transfer Restricted Securities in such capacity) the right to include any of
its securities in the Shelf Registration Statement other than the Transfer
Restricted Securities.

          (d)  Amendments and Waivers.  The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case
of Section 4 hereof and this Section 10(d)(i), the Company has obtained the
written consent of Holders of all outstanding Transfer Restricted Securities
and (ii) in the case of all other provisions hereof, the Company has obtained
the written consent of Holders of Shares representing a majority of the
outstanding liquidation preference of Transfer Restricted Securities (excluding
Transfer Restricted Securities held by the Company or its Affiliates).

<PAGE>   12





          (e)  Third Party Beneficiary.  The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right
to enforce such agreements directly to the extent they may deem such
enforcement necessary or advisable to protect their rights hereunder.

          (f)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air

          (g)  Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent Holders of Transfer Restricted Securities; provided,
that nothing herein shall be deemed to permit any assignment, transfer or other
disposition of Transfer Restricted Securities in violation of the terms hereof
or of the Purchase Agreement or the Certificate of Designation.  If any
transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale
set forth in this Agreement, the Certificate of Designation and, if applicable,
the Purchase Agreement, and such Person shall be entitled to receive the
benefits hereof.

          (h)  Counterparts.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (i)  Headings.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (j)  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND

TO THE CONFLICT OF LAW RULES THEREOF.

          (k)  Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such

provision in every other respect and of the remaining provisions contained
herein shall not be affected or impaired thereby.

SECTION 2.          HOLDERS

          A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "HOLDER") whenever such Person owns Transfer Restricted Securities.

SECTION 3.          REGISTERED EXCHANGE OFFER

          (a)  Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company and the Guarantors shall (i) cause the Exchange
Offer Registration Statement to be filed with the Commission as soon as
practicable after the Closing Date, but in no event later than 60 days after
the Closing Date (such 60th day being the "FILING DEADLINE"), (ii) use their
best efforts to cause such Exchange Offer Registration Statement to become
effective at the earliest possible time, but in no event later than 180 days
after the Closing Date (such 180th day being the "EFFECTIVENESS DEADLINE"),
(iii) in connection with the foregoing, (A) file all pre-effective amendments
to such Exchange Offer Registration Statement as may be necessary in order to
cause it to become effective, (B) file, if applicable, a post-effective
amendment to such Exchange Offer Registration Statement pursuant to Rule 430A
under the Act and (C) cause all necessary filings, if any, in connection with
the registration and qualification of the Series B Notes to be made under the
Blue Sky laws of such jurisdictions as are necessary to permit Consummation of
the Exchange Offer, and (iv) upon the effectiveness of such Exchange Offer
Registration Statement, commence and Consummate the Exchange Offer.  The
Exchange Offer shall be on the appropriate form permitting (1) registration of
the Series B Notes to be offered in exchange for the Series A Notes that are
Transfer Restricted Securities and (2) resales of Series B Notes by any
Broker-Dealer that tendered into the Exchange Offer Series A Notes that such
Broker-Dealer acquired for its own account as a result of market making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any of its Affiliates) as contemplated by Section
3(c) below.

          (b)  The Company and the Guarantors shall use their respective best
efforts to cause the Exchange Offer Registration Statement to be effective
continuously, and shall keep the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
laws to Consummate the Exchange Offer; provided, however, that in no event
shall such period be less than 30 days nor more than 60 days.  The Company and
the Guarantors shall cause the Exchange Offer to comply with all applicable
federal and state securities laws.  No securities other than the Series B Notes
shall be included in the Exchange Offer Registration Statement.  The Company
and the Guarantors shall use their respective best efforts to cause the
Exchange Offer to be Consummated on the earliest practicable date after the
Exchange Offer Registration Statement has become effective, but in no event
later than 60 days after commencement of the Exchange Offer (such 60th day
being the "CONSUMMATION DEADLINE").

          (c)  The Company shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted
Securities that were acquired for the account of such Broker-Dealer as a result
of market-making activities or other trading activities (other than Series A
Notes acquired directly from the Company or any Affiliate of the Company) may
exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission as a result of a change in policy, rules or
regulations after the date of this Agreement.  See the Shearman & Sterling
no-action letter (available July 2, 1993).

          Because such Broker-Dealer may be deemed to be an "underwriter"
within the meaning of the Act and must, therefore, deliver a prospectus meeting
the requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus





                                      -4-
<PAGE>   5
delivery requirement.  To the extent necessary to ensure that the prospectus
contained in the Exchange Offer Registration Statement is available for sales
of Series B Notes by Broker-Dealers, the Company and the Guarantors agree to
use their respective best efforts to keep the Exchange Offer Registration
Statement continuously effective, supplemented, amended and current as required
by and subject to the provisions of Section 6(a) and (c) hereof and in
conformity with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of 180 days from the Consummation Deadline or such shorter period as
will terminate when all Transfer Restricted Securities covered by such
Registration Statement have been sold pursuant thereto.  The Company and the
Guarantors shall provide sufficient copies of the latest version of such
Prospectus to such Broker-Dealers, promptly upon request, and in no event later
than one day after such request, at any time during such period.

SECTION 4.          SHELF REGISTRATION

          (a)  Shelf Registration.  If (i) the Exchange Offer is not permitted
by applicable law (after the Company and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of
Transfer Restricted Securities shall notify the Company within 20 Business Days
following the Consummation Deadline that (A) such Holder was prohibited by law
or Commission policy from participating in the Exchange Offer or (B) such
Holder may not resell the Series B Notes acquired by it in the Exchange Offer
to the public without delivering a prospectus and the Prospectus contained in
the Exchange Offer Registration Statement is not appropriate or available for
such resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Series A Notes acquired directly from the Company or any of its Affiliates,
then the Company and the Guarantors shall:

               (x)  cause to be filed, on or prior to 30 days after the earlier
          of (i) the date on which the Company determines that the Exchange
          Offer Registration Statement cannot be filed as a result of clause
          (a)(i) above and (ii) the date on which the Company receives the
          notice specified in clause (a)(ii) above, (such earlier date, the
          "FILING DEADLINE"), a shelf registration statement pursuant to Rule
          415 under the Act (which may be an amendment to the Exchange Offer
          Registration Statement (the "SHELF REGISTRATION STATEMENT")),
          relating to all Transfer Restricted Securities, and

               (y)  shall use their respective best efforts to cause such Shelf
          Registration Statement to become effective on or prior to 180 days
          after the Filing Deadline for the Shelf Registration Statement (such
          180th day the "EFFECTIVENESS DEADLINE").

          If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Company shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

          To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Company and the Guarantors shall use their respective best efforts
to keep any Shelf Registration Statement required by this Section 4(a)
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Sections 6(b) and (c) hereof and in conformity
with the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
at least two years (as extended pursuant to Section 6(c)(i)) following the
Closing Date, or such shorter period as will terminate when all Transfer
Restricted Securities covered by such Shelf Registration Statement have been
sold pursuant thereto.

          (b)  Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement.  No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 15 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.





                                      -5-
<PAGE>   6
No Holder of Transfer Restricted Securities shall be entitled to liquidated
damages pursuant to Section 5 hereof until 30 days after such Holder shall have
provided all such information.  Each selling Holder agrees to promptly furnish
additional information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

SECTION 5.          LIQUIDATED DAMAGES

          If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation
Deadline or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded (a) within 5 Business
Days by a post-effective amendment to such Registration Statement that cures
such failure and that is itself declared effective within 10 days of filing
such post-effective amendment to such Registration Statement or (b) within 20
days by the filing of a supplement to the Prospectus under Rule 424 of the Act
or an Exchange Act report incorporated by reference in such Registration
Statement that cures such failure (each such event referred to in clauses (i)
through (iv), a "REGISTRATION DEFAULT"), then the Company and the Guarantors
hereby jointly and severally agree to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to one-half
of one percent (0.5%) per annum of the principal amount of the Transfer
Restricted Securities held by such Holder during the first 90-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 Transfer Restricted Securities during each subsequent
90-day period, up to a maximum amount of liquidated damages equal to two
percent (2.0%) per annum of the principal amount of such Transfer Restricted
Securities; provided that the Company and the Guarantors shall in no event be
required to pay liquidated damages for more than one Registration Default at
any given time.  Notwithstanding anything to the contrary set forth herein, (1)
upon filing of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (i) above, (2)
upon the effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4)
upon the filing of (a) a post-effective amendment to the Registration
Statement, a Prospectus supplement or an additional Registration Statement or
(b) a Prospectus supplement or an Exchange Act report incorporated by reference
that causes the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement) to again be declared effective or made usable
in the case of (iv) above, the liquidated damages payable with respect to the
Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

          All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture,
on each Interest Payment Date, as more fully set forth in the Indenture and the
Series A Notes.  Notwithstanding the fact that any securities for which
liquidated damages are due cease to be Transfer Restricted Securities, all
obligations of the Company and the Guarantors to pay liquidated damages with
respect to securities shall survive until such time as such obligations with
respect to such securities shall have been satisfied in full.

SECTION 6.          REGISTRATION PROCEDURES

          (a)  Exchange Offer Registration Statement.  In connection with the
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Series B Notes by
any Broker-Dealer that tendered in the Exchange Offer Series A Notes that such
Broker-Dealer acquired for its own account as a result of its market making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any of its Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply
with all of the following provisions:

               (i)  If, following the date hereof there has been announced a
     change in Commission policy with respect to exchange offers such as the
     Exchange Offer, that in the reasonable opinion of counsel to the Company
     raises a substantial question as to whether the Exchange Offer is
     permitted by applicable federal law, the Company and the





                                      -6-
<PAGE>   7
     Guarantors hereby agree to seek a no-action letter or other favorable
     decision from the Commission allowing the Company and the Guarantors to
     Consummate an Exchange Offer for such Transfer Restricted Securities.  The
     Company and the Guarantors hereby agree to pursue the issuance of such a
     decision to the Commission staff level.  In connection with the foregoing,
     the Company and the Guarantors hereby agree to take all such other actions
     as may be requested by the Commission or otherwise required in connection
     with the issuance of such decision, including without limitation (A)
     participating in telephonic conferences with the Commission staff, (B)
     delivering to the Commission staff an analysis prepared by counsel to the
     Company setting forth the legal bases, if any, upon which such counsel has
     concluded that such an Exchange Offer should be permitted and (C)
     diligently pursuing a resolution (which need not be favorable) by the
     Commission staff.

               (ii)  As a condition to its participation in the Exchange Offer,
     each Holder of Transfer Restricted Securities (including, without
     limitation, any Holder who is a Broker Dealer) shall furnish, upon the
     request of the Company, prior to the Consummation of the Exchange Offer, a
     written representation to the Company and the Guarantors (which may be
     contained in the letter of transmittal contemplated by the Exchange Offer
     Registration Statement) to the effect that (A) it is not an Affiliate of
     the Company, (B) it is not engaged in, and does not intend to engage in,
     and has no arrangement or understanding with any person to participate in,
     a distribution of the Series B Notes to be issued in the Exchange Offer
     and (C) it is acquiring the Series B Notes in its ordinary course of
     business.  Each Holder using the Exchange Offer to participate in a
     distribution of the Series B Notes hereby acknowledges and agrees that, if
     the resales are of Series B Notes obtained by such Holder in exchange for
     Series A Notes acquired directly from the Company or an Affiliate thereof,
     it (1) could not, under Commission policy as in effect on the date of this
     Agreement, rely on the position of the Commission enunciated in Morgan
     Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings
     Corporation (available May 13, 1988), as interpreted in the Commission's
     letter to Shearman & Sterling (available July 2, 1993), and similar
     no-action letters (including, if applicable, any no-action letter obtained
     pursuant to clause (i) above), and (2) must comply with the registration
     and prospectus delivery requirements of the Act in connection with a
     secondary resale transaction and that such a secondary resale transaction
     must be covered by an effective registration statement containing the
     selling security holder and plan of distribution information required by
     Item 507 or 508, as applicable, of Regulation S-K.

               (iii)  Prior to effectiveness of the Exchange Offer Registration
     Statement, the Company and the Guarantors shall provide a supplemental
     letter to the Commission (A) stating that the Company and the Guarantors
     are registering the Exchange Offer in reliance on the position of the
     Commission enunciated in Exxon Capital Holdings Corporation (available May
     13, 1988), Morgan Stanley and Co., Inc. (available June 5, 1991) as
     interpreted in the Commission's letter to Shearman & Sterling (available
     July 2, 1993), and, if applicable, any no-action letter obtained pursuant
     to clause (i) above, (B) including a representation that neither the
     Company nor any Guarantor has entered into any arrangement or
     understanding with any Person to distribute the Series B Notes to be
     received in the Exchange Offer and that, to the best of the Company's and
     each Guarantor's information and belief, each Holder participating in the
     Exchange Offer is acquiring the Series B Notes in its ordinary course of
     business and has no arrangement or understanding with any Person to
     participate in the distribution of the Series B Notes received in the
     Exchange Offer and (C) any other undertaking or representation required by
     the Commission as set forth in any no-action letter obtained pursuant to
     clause (i) above, if applicable.

          (b)  Shelf Registration Statement.  In connection with the Shelf
Registration Statement, (i) the Company and the Guarantors shall (x) comply
with all the provisions of Section 6(c) below and (y) use their respective best
efforts to effect such registration to permit the sale of the Transfer
Restricted Securities being sold in accordance with the intended method or
methods of distribution thereof (as indicated in the information furnished to
the Company pursuant to Section 4(b) hereof), and pursuant thereto the Company
and the Guarantors will prepare and file with the Commission a Registration
Statement relating to the registration on any appropriate form under the Act,
which form shall be available for the sale of the Transfer Restricted
Securities in accordance with the intended method or methods of distribution
thereof within the time periods and otherwise in accordance with the provisions
hereof; and (ii) issue, upon the request of any Holder or purchaser of Series A
Notes covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Notes having an aggregate principal amount equal to the
aggregate principal amount of Series A Notes sold pursuant to the Shelf
Registration Statement and surrendered to the Company for cancellation; the
Company





                                      -7-
<PAGE>   8
shall register Series A Notes on the Shelf Registration Statement for this
purpose and issue the Series B Notes to the purchaser(s) of securities subject
to the Shelf Registration Statement in the names as such purchaser(s) shall
designate.

          (c)  General Provisions.  In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Company
and the Guarantors shall:

               (i)  use their respective best efforts to keep such Registration
     Statement continuously effective and provide all requisite financial
     statements for the period specified in Section 3 or 4 of this Agreement,
     as applicable.  Upon the occurrence of any event that would cause any such
     Registration Statement or the Prospectus contained therein (A) to contain
     an untrue statement of material fact or omit to state any material fact
     necessary to make the statements therein not misleading or (B) not to be
     effective and usable for resale of Transfer Restricted Securities during
     the period required by this Agreement, the Company and the Guarantors
     shall file promptly an appropriate (x) amendment to such Registration
     Statement curing such defect, and, if Commission review is required, use
     their respective best efforts to cause such amendment to be declared
     effective as soon as practicable, (y) supplement pursuant to Rule 424
     under the Act curing such default or (z) Exchange Act report incorporated
     by reference curing such default;

               (ii)  prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such Registration Statement effective for the
     applicable period set forth in Section 3 or 4 hereof, as the case may be;
     cause the Prospectus to be supplemented by any required Prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
     under the Act in a timely manner; and comply with the provisions of the
     Act with respect to the disposition of all securities covered by such
     Registration Statement during the applicable period in accordance with the
     intended method or methods of distribution by the sellers thereof set
     forth in such Registration Statement or supplement to the Prospectus;

               (iii)  advise each Holder and each Initial Purchaser who is
     required to deliver a prospectus in connection with sales or market making
     activities (an "AFFILIATED MARKET MAKER") promptly and, if requested by
     such Person, confirm such advice in writing, (A) when a Registration
     Statement or any Prospectus supplement or post- effective amendment has
     been filed, and, with respect to any applicable Registration Statement or
     any post- effective amendment thereto, when the same has become effective,
     (B) of any request by the Commission for amendments to the Registration
     Statement or amendments or supplements to the Prospectus or for additional
     information relating thereto, (C) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Registration Statement
     under the Act or of the suspension by any state securities commission of
     the qualification of the Transfer Restricted Securities for offering or
     sale in any jurisdiction, or the initiation of any proceeding for any of
     the preceding purposes, (D) of the existence of any fact or the happening
     of any event that makes any statement of a material fact made in the
     Registration Statement, the Prospectus, any amendment or supplement
     thereto or any document incorporated by reference therein untrue, or that
     requires the making of any additions to or changes in the Registration
     Statement or the Prospectus in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.
     If at any time the Commission shall issue any stop order suspending the
     effectiveness of the Registration Statement, or any state securities
     commission or other regulatory authority shall issue an order suspending
     the qualification or exemption from qualification of the Transfer
     Restricted Securities under state securities or Blue Sky laws, the Company
     and the Guarantors shall use their respective best efforts to obtain the
     withdrawal or lifting of such order at the earliest possible time;

               (iv)  subject to Section 6(c)(i), if any fact or event
     contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
     prepare a post-effective amendment or supplement to the Registration
     Statement or related Prospectus or any document incorporated therein by
     reference or file any other required document so that, as thereafter
     delivered to the purchasers of Transfer Restricted Securities, 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, in
     the light of the circumstances under which they were made, not misleading;

               (v)   upon the request of counsel for the Holders and for any
     Affiliated Market Makers, furnish to such counsel or Affiliated Market
     Maker before filing with the Commission, copies of any Registration
     Statement or any Prospectus included therein or any amendments or
     supplements to any such Registration Statement or Prospectus (including
     all documents incorporated by reference after the initial filing of such
     Registration Statement), which documents will be subject to the review and
     comment of such counsel for a period of at least five Business Days, and
     the Company will not file any such Registration Statement or Prospectus or
     any amendment or supplement to any such Registration Statement or
     Prospectus (including all such documents incorporated by reference) to
     which such Persons shall reasonably object within five Business Days after
     the receipt thereof.  Such Person shall be deemed to have reasonably
     objected to such filing if such Registration Statement, amendment,
     Prospectus or supplement, as applicable, as proposed to be filed, contains
     an untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein not misleading or fails to comply
     with the applicable requirements of the Act;

               (vi) upon the request of any Holder or Affiliated Market Maker,
     provide copies of any document filed with the Commission that is
     incorporated by reference into a Registration Statement or Prospectus, and
     make the Company's and the Guarantors' representatives available for
     discussion of such document and other customary due diligence matters;

               (vii)  make available, at reasonable times, for inspection by
     each Holder and each Affiliated Market Maker and any attorney or
     accountant retained by such Persons, all financial and other records,
     pertinent corporate documents of the Company and the Guarantors and cause
     the Company's and the Guarantors' officers and employees to supply all
     information reasonably requested by any such Persons, attorney or
     accountant in connection with such Registration Statement or any
     post-effective amendment thereto subsequent to the filing thereof and
     prior to its effectiveness;

               (viii)  if requested by any Holders or any Affiliated Market
     Maker, promptly include in any Registration Statement or Prospectus,
     pursuant to a supplement or post-effective amendment if necessary, such
     information as such Persons may reasonably request to have included
     therein including, without limitation, information relating to the "Plan
     of Distribution" of the Transfer Restricted Securities and the use of the
     Registration Statement or Prospectus for market making activities; and
     make all required filings of such Prospectus supplement or post- effective
     amendment as soon as practicable after the Company is notified of the
     matters to be included in such Prospectus supplement or post-effective
     amendment;

               (ix) upon the request of any Holder or Affiliated Market Maker,
     furnish to such Holder or Affiliated Market Maker, without charge, at
     least one copy of the Registration Statement, as first filed with the
     Commission, and of each amendment thereto;

               (x)  deliver to each Holder and each Affiliated Market Maker
     without charge, as many copies of the Prospectus (including each
     preliminary prospectus) and any amendment or supplement thereto as such
     Persons reasonably may request; the Company and the Guarantors hereby
     consent to the use (in accordance with law) of the Prospectus and any
     amendment or supplement thereto by each selling Person in connection with
     the offering and the sale of the Transfer Restricted Securities covered by
     the Prospectus or any amendment or supplement thereto and all market
     making activities of such Affiliated Market Maker, as the case may be;

               (xi)  upon the request of any Holder or Affiliated Market Maker,
     enter into such agreements (including underwriting agreements) and make
     such representations and warranties and take all such other actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any applicable Registration
     Statement contemplated by this Agreement as may be reasonably requested by
     any Holder in connection with any sale or resale pursuant to any
     applicable Registration Statement.  In such connection, and also in
     connection with market making activities by any Affiliated Market Maker,
     the Company and the Guarantors shall:





                                      -9-
<PAGE>   10
                          (A)  upon request of such Holder or Affiliated Market
          Maker, furnish (or in the case of paragraphs (2) and (3), use its
          best efforts to cause to be furnished) to each Person, upon
          Consummation of the Exchange Offer or upon the effectiveness of the
          Shelf Registration Statement, as the case may be:

                                    (1)  a certificate, dated such date, signed
               on behalf of the Company and each Guarantor by (x) the Chairman
               of the Board, President or any Vice President and (y) a
               principal financial or accounting officer of the Company and
               such Guarantor, confirming, as of the date thereof, the matters
               set forth in Sections 6(y), 9(a) and 9(b) of the Purchase
               Agreement and such other similar matters as such Person may
               reasonably request;

                                    (2)  an opinion, dated the date of
               Consummation of the Exchange Offer or the date of effectiveness
               of the Shelf Registration Statement, as the case may be, of
               counsel for the Company and the Guarantors covering matters
               similar to those set forth in paragraph (e) of Section 9 of the
               Purchase Agreement and such other matter as such Holder or
               Affiliated Market Maker may reasonably request, and in any event
               including a statement to the effect that such counsel has
               participated in conferences with officers and other
               representatives of the Company and the Guarantors,
               representatives of the independent public accountants for the
               Company and the Guarantors and has considered the matters
               required to be stated therein and the statements contained
               therein, although such counsel has not independently verified
               the accuracy, completeness or fairness of such statements; and
               that such counsel advises that, on the basis of the foregoing
               (relying as to materiality to the extent such counsel deems
               appropriate upon the statements of officers and other
               representatives of the Company and the Guarantors and without
               independent check or verification), no facts came to such
               counsel's attention that caused such counsel to believe that the
               applicable Registration Statement and any post-effective
               amendment thereto, at the time such Registration Statement or
               any post-effective amendment thereto became effective and, in
               the case of the Exchange Offer Registration Statement, as of the
               date of Consummation of the Exchange Offer, contained an untrue
               statement of a material fact or omitted to state a material fact
               required to be stated therein or necessary to make the
               statements therein, in the light of the circumstances under
               which they were made, not misleading, or that the Prospectus
               contained in such Registration Statement as of its date and, in
               the case of the opinion dated the date of Consummation of the
               Exchange Offer, as of the date of Consummation, contained an
               untrue statement of a material fact or omitted to state a
               material fact necessary in order to make the statements therein,
               in the light of the circumstances under which there were made,
               not misleading.  Without limiting the foregoing, such counsel
               may state further that such counsel assumes no responsibility
               for, and has not independently verified, the accuracy,
               completeness or fairness of the financial statements, notes and
               schedules and other financial data included in any Registration
               Statement contemplated by this Agreement or the related
               Prospectus; and

                                    (3)  a customary comfort letter, dated the
               date of Consummation of the Exchange Offer, or as of the date of
               effectiveness of the Shelf Registration Statement, as the case
               may be, from the Company's independent accountants, in the
               customary form and covering matters of the type customarily
               covered in comfort letters to underwriters in connection with
               underwritten offerings, and affirming the matters set forth in
               the comfort letters delivered pursuant to Section 9(i) of the
               Purchase Agreement; and

                          (B) deliver such other documents and certificates as
          may be reasonably requested by such Persons to evidence compliance
          with the matters covered in clause (A) above and with any customary
          conditions contained in the any agreement entered into by the Company
          and the Guarantors pursuant to this clause (xi);

               (xii)  prior to any public offering of Transfer Restricted
     Securities, cooperate with the selling Holders and their counsel in
     connection with the registration and qualification of the Transfer
     Restricted Securities under the securities or Blue Sky laws of such
     jurisdictions as the selling Holders may request and do any and all other
     acts or things necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the
     applicable Registration Statement; provided, however, that neither the
     Company nor any Guarantor





                                      -10-
<PAGE>   11
     shall be required to register or qualify as a foreign corporation where it
     is not now so qualified or to take any action that would subject it to the
     service of process in suits or to taxation, other than as to matters and
     transactions relating to the Registration Statement, in any jurisdiction
     where it is not now so subject;

               (xiii)  in connection with any sale of Transfer Restricted
     Securities that will result in such securities no longer being Transfer
     Restricted Securities, cooperate with the Holders to facilitate the timely
     preparation and, subject to the Indenture, delivery of certificates
     representing Transfer Restricted Securities to be sold and not bearing any
     restrictive legends; and, subject to the Indenture, to register such
     Transfer Restricted Securities in such denominations and such names as the
     selling Holders may request at least two Business Days prior to such sale
     of Transfer Restricted Securities;

               (xiv)  use their respective best efforts to cause the
     disposition of the Transfer Restricted Securities covered by the
     Registration Statement to be registered with or approved by such other
     governmental agencies or authorities as may be required to enable the
     seller or sellers thereof to consummate the disposition of such Transfer
     Restricted Securities, subject to the proviso contained in clause (xii)
     above;

               (xv)  provide a CUSIP number for the Series B Notes not later
     than the effective date of an Exchange Offer Registration Statement
     covering such Transfer Restricted Securities and provide the Trustee under
     the Indenture with printed certificates for the Transfer Restricted
     Securities which are in a form eligible for deposit with The Depository
     Trust Company;

               (xvi)  otherwise use their respective best efforts to comply
     with all applicable rules and regulations of the Commission, and make
     generally available to its security holders with regard to any applicable
     Registration Statement, as soon as practicable, a consolidated earnings
     statement meeting the requirements of Rule 158 (which need not be audited)
     covering a twelve-month period beginning after the effective date of the
     Registration Statement (as such term is defined in paragraph (c) of Rule
     158 under the Act); and

               (xvii)  cause the Indenture to be qualified under the TIA not
     later than the effective date of the first Registration Statement required
     by this Agreement and, in connection therewith, cooperate with the Trustee
     and the Holders to effect such changes to the Indenture as may be required
     for such Indenture to be so qualified in accordance with the terms of the
     TIA; and execute and use their best efforts to cause the Trustee to
     execute, all documents that may be required to effect such changes and all
     other forms and documents required to be filed with the Commission to
     enable such Indenture to be so qualified in a timely manner.

          (d)  Restrictions on Holders.  Each Holder agrees by acquisition of a
Transfer Restricted Security and each Affiliated Market Maker agrees that, upon
receipt of (i) the notice referred to in Section 6(c)(iii)(C), (ii) any notice
from the Company of the existence of any fact of the kind described in Section
6(c)(iii)(D) hereof or (ii) any notice from the Company that (a) sales under
any Registration Statement contemplated by this Agreement would require the
disclosure of material information which the Company has a bona fide business
purpose for preserving as confidential, or (b) such disclosure would impede the
Company's ability to consummate a material transaction (in each case, a
"SUSPENSION NOTICE"), such Person will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration
Statement until (A) such Holder or Affiliated Market Maker has received copies
of the supplemented or amended Prospectus contemplated by Section 6(c)(iv)
hereof, or (B) such Holder or Affiliated Market Maker is advised in writing by
the Company that the use of the Prospectus may be resumed, and has received
copies of any additional or supplemental filings that are incorporated by
reference in the Prospectus (in each case, the "RECOMMENCEMENT DATE"),
provided, that any suspension pursuant to clause (iii) above shall not exceed
60 days in any twelve-month period.  Each Holder or Affiliated Market Maker
receiving a Suspension Notice hereby agrees that it will either (x) destroy any
Prospectuses, other than permanent file copies, then in such Person's
possession which have been replaced by the Company with more recently dated
Prospectuses or (y) deliver to the Company (at the Company's expense) all
copies, other than permanent file copies, then in such Holder's or Affiliated
Market Maker's possession of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of the Suspension Notice.
The time period regarding the effectiveness of such Registration Statement set
forth in Section 3 or 4 hereof, as applicable, shall be extended by a number of
days equal to the number of days in the period from and including the date of
delivery of the Suspension Notice to the date of delivery of the Recommencement
Date.

SECTION 7.          REGISTRATION EXPENSES

          (a)  All expenses incident to the Company's and the Guarantors'
performance of or compliance with this Agreement will be borne by the Company,
regardless of whether a Registration Statement becomes effective, including
without limitation: (i) all registration and filing fees and expenses; (ii) all
fees and expenses of compliance with federal securities and state Blue Sky or
securities laws; (iii) all expenses of printing (including printing
certificates for the Series B Notes to be issued in the Exchange Offer and
printing of Prospectuses whether for exchanges, sales, market making or
otherwise), messenger and delivery services and telephone; (iv) all fees and
disbursements of counsel for the Company and the Guarantors, and not more than
one counsel for the Holders of Transfer Restricted Securities as described in
Section 7(b) below; (v) all application and filing fees in connection with
listing the Series B Notes on a national securities exchange or automated
quotation system pursuant to the requirements hereof; and (vi) all fees and
disbursements of independent certified public accountants of the Company and
the Guarantors (including the expenses of any special audit and comfort letters
required by or incident to such performance).

          The Company will, in any event, bear its and the Guarantors' internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company or the Guarantors.

          (b)  In connection with any Registration Statement required by this
Agreement, the Company and the Guarantors will reimburse the Initial Purchasers
and the Holders of Transfer Restricted Securities who are tendering Series A
Notes into in the Exchange Offer and/or selling or reselling Series A Notes or
Series B Notes pursuant to the "Plan of Distribution" contained in the Exchange
Offer Registration Statement or the Shelf Registration Statement, as
applicable, for the reasonable fees and disbursements of not more than one
counsel, who shall be Andrews & Kurth L.L.P., unless another firm shall be
chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit such Registration Statement is being
prepared.

SECTION 8.          INDEMNIFICATION

          (a)  The Company and the Guarantors agree, jointly and severally, to
indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all
losses, claims, damages, liabilities, judgments, (including without limitation,
any legal or other expenses incurred in connection with investigating or
defending any matter, including any action that could give rise to any such
losses, claims, damages, liabilities or judgments) caused by any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement, preliminary prospectus or Prospectus (or any amendment
or supplement thereto) provided by the Company to any Holder or any prospective
purchaser of Series B Notes or registered Series A Notes, 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 not misleading,
except insofar as such losses, claims, damages, liabilities or judgments are
caused by an untrue statement or omission or alleged untrue statement or
omission that is based upon information relating to any of the Holders
furnished in writing to the Company by any of the Holders.

          (b)  Each Holder of Transfer Restricted Securities agrees, severally
and not jointly, to indemnify and hold harmless the Company and the Guarantors,
and their respective directors and officers, and each person, if any, who
controls (within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act) the Company or the Guarantors to the same extent as the foregoing
indemnity from the Company and the Guarantors set forth in section (a) above,
but only with reference to information relating to such Holder furnished in
writing to the Company by such Holder expressly for use in any Registration
Statement.  In no event shall any Holder, its directors, officers or any Person
who controls such Holder be liable or responsible for any amount in excess of
the amount by which the total amount received by such Holder with respect to
its sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages that such Holder,





                                      -12-
<PAGE>   13
its directors, officers or any Person who controls such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.

          (c)  In case any action shall be commenced involving any Person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the Person
against whom such indemnity may be sought (the "INDEMNIFYING PERSON") in
writing and the indemnifying party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel, as incurred
(except that in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required
to assume the defense of such action pursuant to this Section 8(c), but may
employ separate counsel and participate in the defense thereof, but the fees
and expenses of such counsel, except as provided below, shall be at the expense
of the Holder).  Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) for all indemnified parties and all such
fees and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by a majority of the Holders, in the case of the parties
indemnified pursuant to Section 8(a), and by the Company and Guarantors, in the
case of parties indemnified pursuant to Section 8(b). The indemnifying party
shall indemnify and hold harmless the indemnified party from and against any
and all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel
(in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request.  No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

          (d)  To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
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 (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Guarantors, on the one hand, and the Holders, on the other
hand, from their sale of Transfer Restricted Securities or (ii) if the
allocation provided by clause 8(d)(i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause 8(d)(i) above but also the relative fault of the Company
and the Guarantors, on the one hand, and of the Holder, on the other hand, 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
Guarantors, on the one hand, and of the Holder, on the other hand, 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 or such
Guarantor, on the one hand, or by the Holder, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and judgments





                                      -13-

referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 7(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 Guarantors and each Holder agree that it would not
be just and equitable if contribution pursuant to this Section 8(d) were
determined by pro rata allocation (even if the Holders were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in the immediately
preceding paragraph.  The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities or judgments referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any
matter, including any action that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 8, no Holder, its directors, its officers or any Person, if any, who
controls such Holder shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total received by such Holder with
respect to the sale of Transfer Restricted Securities pursuant to a
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages which such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Holders' obligations to contribute pursuant
to this Section 8(d) are several in proportion to the respective principal
amount of Transfer Restricted Securities held by each Holder hereunder and not
joint.

     (e)  The Company and Guarantors agree that the indemnity and contribution
provisions of this Section 8 shall apply to Affiliated Market Makers to the
same extent, on the same conditions, as it applies to Holders.

SECTION 9.          RULE 144A AND RULE 144

          The Company and each Guarantor agree with each Holder, for so long as
any Transfer Restricted Securities remain outstanding and during any period in
which the Company or such Guarantor (i) is not subject to Section 13 or 15(d)
of the Exchange Act, to make available, upon request of any Holder, to such
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of such Transfer Restricted
Securities designated by such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to
Section 13 or 15 (d) of the Exchange Act, to make all filings required thereby
in a timely manner in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144 (if available).

SECTION 10.         MISCELLANEOUS

          (a)  Remedies.  The Company and the Guarantors acknowledge and agree
that any failure by the Company and/or the Guarantors to comply with their
respective obligations under Sections 3 and 4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders or Affiliated
Market Makers for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchasers or any Holder or Affiliated Market
Makers may obtain such relief as may be required to specifically enforce the
Company's and the Guarantors' obligations under Sections 3 and 4 hereof.  The
Company and the Guarantors further agree to waive the defense in any action for
specific performance that a remedy at law would be adequate.

          (b)  No Inconsistent Agreements.  Neither the Company nor any
Guarantor will, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof.  Neither the Company nor any Guarantor has previously
entered into any agreement granting any registration rights with respect to its
securities to any Person, except as disclosed in the Purchase Agreement.  The
rights granted to the Holders hereunder do not in any way conflict with and are
not inconsistent with the rights granted to the holders of the Company's and
the Guarantors' securities under any agreement in effect on the date hereof.

          (c)  No Piggybacks on Shelf Registration Statement.  The Company
shall not grant to any of its security holders (other than the holders of
Transfer Restricted Securities in such capacity) the right to include any of
its securities in any Registration Statement provided for in this Agreement
other than the Transfer Restricted Securities.

          (d)  Amendments and Waivers.  The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case
of Section 5 hereof and this Section 10(d)(i), the Company has obtained the
written consent of Holders of all outstanding Transfer Restricted Securities
and (ii) in the case of all other provisions hereof, the Company has obtained
the written consent of Holders of a majority of the outstanding principal
amount of Transfer Restricted Securities (excluding Transfer Restricted
Securities held by the Company or its Affiliates).  Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose Transfer Restricted
Securities are being tendered pursuant to the Exchange Offer, and that does not
affect directly or indirectly the rights of other Holders whose Transfer
Restricted Securities are not being tendered pursuant to such Exchange Offer,
may be given by the Holders of a majority of the outstanding principal amount
of Transfer Restricted Securities subject to such Exchange Offer.

          (e)  Third Party Beneficiary.  The Holders and Affiliated Market
Makers shall be third party beneficiaries to the agreements made hereunder
between the Company and the Guarantors, on the one hand, and the Initial
Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent they may deem such enforcement necessary or
advisable to protect their rights hereunder.

          (f) Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

               All such notices and communications shall be deemed to have been
duly given:  at the time delivered by hand, if personally delivered; five
Business Days after being deposited in the mail, postage prepaid, if mailed;

          Upon the date of filing of the Exchange Offer or a Shelf Registration

Jenrette Securities Corporation, on behalf of the Initial Purchasers (in the
form attached hereto as Exhibit A) and shall be addressed to:  Attention:
Louise Guarneri (Compliance Department), 277 Park Avenue, New York, New York
10172.

          (f)  Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent Holders; provided, that nothing herein shall be deemed
to permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement or the
Indenture.  If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities shall be held subject to all of the terms of
this Agreement, and by taking and holding such Transfer Restricted Securities
such Person shall be conclusively deemed to have agreed to be bound by and to
perform all of the terms and provisions of this Agreement, including the
restrictions on resale set forth in this Agreement, the Indenture and, if
applicable, the Purchase Agreement, and such Person shall be entitled to
receive the benefits hereof.

          (g)  Counterparts.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h)  Headings.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (i)  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE CONFLICT OF LAW RULES THEREOF.

          (j)  Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

          (k)  Entire Agreement.  This Agreement is intended by the parties as
a final expression of their agreement and intended to be a complete and
exclusive statement of the agreement and understanding of the parties hereto in
respect of the subject matter contained herein.  There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to
herein with respect to the registration rights granted with respect to the
Transfer Restricted Securities.  This Agreement supersedes all prior agreements
and understandings between the parties with respect to such subject matter.
