CROSS TIMBERS OIL COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


1.   INTERIM FINANCIAL STATEMENTS

     The accompanying consolidated financial statements of Cross Timbers Oil
Company ("the Company"), with the exception of the consolidated balance sheet at
December 31, 1996, have not been audited by independent public accountants.  In
the opinion of the Company's management, the accompanying financial statements
reflect all adjustments necessary to present fairly the financial position at
March 31, 1997 and the results of operations and cash flows of the Company for
the three months ended March 31, 1997 and 1996.  All such adjustments are of a
normal recurring nature.  Certain amounts presented in prior period financial
statements have been reclassified for consistency with current period
presentation.  The results for interim periods are not necessarily indicative of
annual results.

     Certain disclosures have been condensed or omitted from these financial
statements.  Accordingly, these financial statements should be read with the
Company's consolidated financial statements included in the Company's 1996
annual report on Form 10-K.

2.   LONG-TERM DEBT

     In January 1997, $29.7 million principal amount of the Company's 5 1/4%
convertible subordinated notes was converted by note holders into 1,928,242
shares of common stock and $29,000 was redeemed.  As of January 21, 1997, no 
5 1/4% convertible subordinated notes remained outstanding.

     On April 2, 1997, the Company sold $125 million of 9 1/4% senior
subordinated notes ("Notes") to qualified institutional buyers pursuant to Rule
144A of the Securities Act of 1933. The Notes are general unsecured indebtedness
that is subordinate to bank borrowings under the Revolving Credit Agreement. The
Notes mature on April 1, 2007 and interest is payable each April 1 and October
1. The Notes are redeemable at the option of the Company on April 1, 2002 at a
price of 104.625%, and thereafter at prices declining ratably annually to 100%
on April 1, 2005, plus accrued interest through the redemption date. In
addition, on or prior to April 1, 2000, the Company may, subject to certain
requirements, redeem up to one-third of the Notes with the net proceeds from one
or more public equity offerings at a price equal to 109.25% plus accrued
interest. Upon a change in control (as defined) of the Company, Note holders
have the right to require the Company to purchase all or a portion of their
Notes at 101% plus accrued interest. See also Note 3.

     On March 31, 1997, outstanding bank borrowings and short-term borrowings
were $300 million and $3.4 million respectively. On April 2, outstanding bank
borrowings were reduced to $181.9 million after applying net proceeds of $121.5
million (before estimated offering expenses of $454,000) from the sale of the
Notes. As of April 2, 1997, total bank borrowing commitments were $274 million,
with resulting unused borrowing capacity of $92.1 million. Because of this
increased borrowing capacity, short-term borrowings at March 31 were
reclassified to long-term debt. Borrowing commitments will be reduced to $265.8
million and $257.6 million on June 30, 1997 and December 31, 1997, respectively.

     As of April 2, 1997, there are no maturities of long-term debt through
1999; maturities in 2000 and 2001 are $45 million and $44.1 million,
respectively.

3.   COMMITMENTS

     The Company has entered contracts with two purchasers to sell a total of
60,000 Mcf of gas per day from June through October for delivery in Oklahoma at
a weighted average sales price of $1.97 per Mcf, before Btu and gathering charge
adjustments.  The Company has also entered in a commodity price swap agreement
effectively fixing the Company's gas price on notional volumes of 10,000 Mcf per
day of Oklahoma deliveries from June through October at $1.93 per Mcf, before
Btu and gathering charge adjustments.

                                                                               6
<PAGE>
 
     The Company has entered a registration rights agreement with the purchasers
of the Notes (Note 2) to use its best efforts to register notes ("Exchange
Notes") with the Securities and Exchange Commission ("Commission") that the
purchasers may exchange for the Notes, and to effect the offering of such
exchange ("Exchange Offering"). The Exchange Notes will have substantially
identical terms as the Notes, except that the Exchange Notes will not have
transfer restrictions. The Company's registration statement on Form S-4 to
register the Exchange Notes was declared effective by the Commission on May 14,
1997. If the Exchange Offering is not consummated by September 29, 1997, the
interest rate on the Notes will increase by 0.50% per annum .

4.   COMMON SHARES OUTSTANDING AND EARNINGS PER COMMON SHARE

     On March 19, 1997, the Company effected a three-for-two common stock split.
All share and per share amounts have been restated to reflect the stock split on
a retroactive basis.

     Fully diluted earnings per share includes the effect of outstanding stock
options (calculated on the treasury stock method) and Series A convertible
preferred stock and 5 1/4% convertible subordinated notes, as if converted on
January 1, 1997.

     In March 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, Earnings Per Share, which
changes the method of computing and disclosing earnings per share for periods
ending after December 15, 1997.  The Company has determined that basic and
diluted earnings per share (as defined by SFAS No. 128) would be the same as
primary and fully diluted earnings per share, respectively, for the three months
ended March 31, 1997 and 1996.

5.   SUPPLEMENTAL CASH FLOW INFORMATION


     The following are total interest and income tax payments during each of the

7.   ACQUISITIONS

     From July 1996 through March 1997, the Company purchased 19% of the
outstanding units of beneficial interest in the Royalty Trust ("Units") at a
cost of $15.4 million, funded primarily with bank debt.  The Board of Directors
has authorized the purchase of up to two million, or 33%, of the outstanding
Units.

     On July 19, 1996, the Company acquired primarily gas-producing properties
in the Green River Basin of southwestern Wyoming from Enserch Exploration
("Enserch Acquisition") for an adjusted purchase price of $39.4 million. The
properties primarily consist of operated interests in the Fontenelle, Nitchie
Gulch and Pine Canyon fields. On November 21, 1996, the Company acquired
additional interests in the Fontenelle Unit, the most significant property
included in the Enserch Acquisition, for an estimated adjusted purchase price of
$12.5 million. These acquisitions were funded by bank debt and cash flow from
operations.

     On December 2, 1996, the Company acquired primarily gas-producing
properties in the Northern Val Verde area of the Permian Basin of West Texas.
The properties are primarily operated interests in the Henderson, Ozona and
Davidson Ranch fields. The adjusted purchase price of $28.1 million was funded
by bank debt and cash flow from operations.

     These acquisitions have been recorded using the purchase method of
accounting.  The following presents unaudited pro forma results of operations
for the three months ended March 31, 1996 and the year ended December 31, 1996,
as if these acquisitions had been consummated as of January 1, 1996.  These pro
forma results are not necessarily indicative of future results.

     On May 14, 1997, the Company acquired producing properties and undeveloped
acreage in Oklahoma, Kansas and Texas for $39.5 million from a subsidiary of
Burlington Resources Inc. The purchase price will be reduced by net revenues
from the effective date of April 1, 1997 through the May 14 closing date. The
properties are primarily operated interests. The Company's internal engineers
estimate related proved reserves to be 36.5 billion cubic feet equivalent of
natural gas, of which more than 97% is gas. Approximately 30% of the purchase
price is attributable to 124 square miles (79,500 net acres) of undeveloped
acreage primarily located in Texas County, Oklahoma. The Company funded the
acquisition with bank debt and cash flow from operations.

                                                                               8

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


Cross Timbers Oil Company:

We have reviewed the accompanying consolidated balance sheet of Cross Timbers
Oil Company (a Delaware Corporation) as of March 31, 1997 and the related
consolidated statements of operations and cash flows for the three-month periods
ended March 31, 1997 and 1996.  These financial statements are the
responsibility of the Company's management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, the objective of which
is the expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should
be made to the consolidated financial statements referred to above for them to
be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Cross Timbers Oil Company as of
December 31, 1996 included in the Company's 1996 annual report on Form 10-K, and
in our report dated March 13, 1997, we expressed an unqualified opinion on that
statement.  In our opinion, the information set forth in the accompanying
consolidated balance sheet as of December 31, 1996 is fairly stated, in all
material respects, in relation to the consolidated balance sheet included in the
Company's 1996 annual report on Form 10-K from which it has been derived.

     Oil production increased because of development activity and acquisitions,
partially offset by property sales and natural decline.  Increased gas
production is primarily attributable to the acquisitions and development
activity.

     The average posted price for West Texas Intermediate ("WTI"), a benchmark
crude, was $21.01 per barrel for first quarter 1997, compared to $18.07 for
first quarter 1996.  The Company's average oil price includes oil marketing
margins, which are partially offset by lower priced sour crude sales and
transportation charges.  As the market reacted to concerns about oversupplies,
oil prices steadily declined during the first quarter of 1997 from December 1996
and January 1997 highs.  The average posted WTI price for April 1997 was 
$18.11, but has rebounded in May to $19.50. 

     After reaching highs in December 1996 and January 1997, natural gas prices
subsequently declined with warmer than normal late winter weather. Gas prices
have rebounded in April and May because of cooler than normal spring weather.
The Company has entered sales contracts and commodity price swap agreements
effectively fixing its price from June through October 1997 on 60,000 Mcf per
day at an average price of $1.97 and 10,000 Mcf per day at $1.93, before Btu and
gathering charge adjustments. See Note 3 to Consolidated Financial Statements.

RESULTS OF OPERATIONS
- ---------------------

     First quarter 1997 earnings were $10.7 million compared to $4.7 million for
first quarter 1996.  Record quarterly earnings were primarily the result of
higher oil and gas production and prices.

     Total revenues for the 1997 quarter were $53.5 million, a 48% increase over
first quarter 1996 revenues of $36.1 million. Oil revenue increased $3.6 million
(22%) because of the 14% increase in average prices and the 7% increase in
production. Gas revenue increased $13.9 million (89%) as a result of the 42%
increase in average prices and the 33% increase in production. Gas gathering,
processing and marketing revenues decreased $1.1 million (29%) primarily because
of a 66% decline in gas marketing margins. Other revenues of $1.3 million in
first quarter 1997 included gains on sale of property and equity securities of
$200,000 and $1.2 million, respectively.

     Expenses for first quarter 1997 totaled $36.5 million, a 25% increase
compared to $29.1 million total expenses for the first quarter of 1996.
Production expense increased $700,000 (7%) and depreciation, depletion and
amortization ("DD&A") increased $1.9 million (21%) primarily because of the 1996
acquisitions. Taxes on production and property for first quarter 1997 increased
$1.4 million (52%) over first quarter 1996 because of increased oil and gas
revenues and property taxes related to the 1996 acquisitions.

     General and administrative expense increased $1 million (38%) primarily
because of Company growth and a $400,000 increase in stock incentive
compensation related to vesting and grants of performance shares. Interest
expense increased $1.3 million (34%) because of borrowings to fund the 1996
acquisitions (net of subordinated note conversions into common stock) and an
increase in the weighted average interest rate from 6.2% in first quarter 1996
to 6.9% in first quarter 1997. Gas gathering and processing expense increased
$1.2 million (135%) because of lease rentals that began following the sales and
operating leasebacks of the Tyrone plant in March 1996 and the Major County,
Oklahoma gathering system in November 1996.

 </TABLE>

     ____________________________________________

     (a) Includes only DD&A directly related to oil and gas production.


Production- Decreased production expense per BOE is because of lower operating
costs of gas-producing properties acquired in 1996, the timing of workovers and
operating efficiencies initiated after acquiring operated properties.

Taxes on production and property- Increased taxes per BOE are primarily because
of increased property tax rates and increased production taxes resulting from
higher oil and gas prices.

                                                                              11
<PAGE>
 
DD&A- Increased DD&A per BOE is primarily related to increased exploitation and
development costs of producing properties.

G&A- Increased G&A per BOE is attributable to stock incentive compensation.
Excluding stock incentive compensation, G&A per BOE was $1.16 and $1.19 for the
first quarter of 1997 and 1996, respectively.

Interest- Increased interest expense per BOE is because of an 11% increase in
the weighted average interest rate.


LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

CASH FLOW AND WORKING CAPITAL


     Cash provided by operating activities was $39.1 million for the first
quarter of 1997 compared to $16.9 million for the comparable 1996 period.
Operating cash flow (defined as cash provided by operating activities before
changes in working capital) increased 79% from $15.2 million for the first
quarter of 1996 to $27.2 million for the same 1997 period. Stock appreciation
right payments reduced first quarter 1996 operating cash flow by $500,000.

     During the quarter ended March 31, 1997, proceeds from bank and short-term
borrowings of $62.5 million, operating activities of $39.1 million, property and
equity security sales of $7.5 million and stock option exercises of $100,000
were used to fund property acquisitions, development costs, other capital
additions and investments in equity securities of $46.1 million, debt payments
of $47.1 million, treasury stock purchases of $17.7 million and dividends of
$1.9 million. The resulting decrease in cash and cash equivalents for the period
was $3.6 million.

     Other significant changes in current assets during the first three months
of 1997 were a $10.9 million decrease in accounts receivable because of lower
March product prices and a $1.1 million decrease in other current assets
resulting from year-end tubular stock that was used in first quarter
exploitation and development.

     Total current liabilities decreased $7.7 million during first quarter 1997.
Accounts payable and accrued liabilities declined $4.5 million primarily because
of lower drilling and development related payables and lower gas gathering,
processing and marketing payables attributable to lower March gas prices. Short-
term debt declined $3 million because of increased bank borrowing capacity
following the sale of senior subordinated notes on April 2, 1997. See Note 2 to
Consolidated Financial Statements.

ACQUISITIONS AND DEVELOPMENT

     Exploitation and development costs incurred by the Company for the first
three months of 1997 were $11.7 million; expenditures for exploitation and
development for this period totaled $17.4 million. This compares with
exploitation and development expenditures of $3.5 million during the first
quarter of 1996. Although actual exploitation and development expenditures may
vary significantly due to many factors, the Company anticipates its 1997
expenditures for exploitation and development activities to approximate its
previously announced $70 million budget. Such expenditures are expected to be
funded by cash flow from operations. During the quarter ended March 31, 1997,
the Company's purchases of equity securities (for non-trading purposes) totaled
$6.5 million; proceeds from sales of equity securities totaled $7 million.

     On April 10, 1997, the Company announced that its Board of Directors
authorized the purchase of up to two million shares of the Company's common
stock, or about 7% of shares outstanding. These purchases are in addition to the
three million share program (adjusted for the March 1997 three-for-two stock
split) announced in May 1996, which was completed in April 1997.

     As of the end of March, the Company had completed drilling 11 oil wells and
seven gas wells in 1997. A total of 12 recompletions and workovers were also
completed in the first quarter. Oil development during the

                                                                              12
<PAGE>
 
quarter focused on the Prentice Northeast Unit in West Texas, while gas
development has been concentrated in the Fontenelle Unit in the Green River
Basin of Wyoming.

     Six of the 11 oil wells drilled to date have been 10-acre infill wells in
the Prentice Northeast Unit where 31 wells are to be drilled by year-end. Three
of the seven gas wells are located in the Fontenelle Unit; wells completed in
the Fontenelle Unit during the first quarter have exceeded expectations with 
daily rates averaging 1,500 Mcf per well. Thirty wells are expected to be
completed by year-end in the Fontenelle Unit where one rig is currently active
and a second is scheduled to begin drilling by the end of May.
 
DEBT AND EQUITY

     During the first quarter of 1997, long-term debt and short-term debt
decreased $11.4 million and $3 million, respectively, reflecting the $29.7
million conversion of the Company's 5 1/4% subordinated notes into common stock,
offset by bank and short-term borrowings of $15.3 million that were used to
partially fund property acquisitions and treasury stock purchases. Stockholders'
equity at March 31, 1997 increased $21 million from year-end primarily because
of the $29.7 million conversion of subordinated notes into common stock and
first quarter earnings of $10.7 million, partially offset by treasury stock
additions of $18 million and common stock dividends of $1.5 million.

     A three-for-two common stock split was effected on March 19, 1997. All
share and per share amounts have been restated for the effect of this stock
split.

     On April 2, 1997, the Company sold $125 million of 9 1/4% senior
subordinated notes to qualified institutional buyers pursuant to Rule 144A of
the Securities Act of 1933. The notes are general unsecured indebtedness that is
subordinate to bank borrowings under the Revolving Credit Agreement. The notes
mature on April 1, 2007 and interest is payable each April 1 and October 1. See
Note 2 to Consolidated Financial Statements.

DIVIDENDS

     In February 1997, the Board of Directors of the Company declared a first
quarter common stock dividend of $0.055 per share, or a total of $1.5 million,
paid in April 1997. Dividends paid by the Company or its predecessors from
September 1992 through January 1997 were at the rate of $0.05 per share.

ACCOUNTING PRONOUNCEMENTS
- -------------------------

     In March 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, Earnings Per Share, which
changes the method of computing and disclosing earnings per share for periods
ending after December 15, 1997. Upon the Company's adoption as of December 31,
1997, restatement of some prior periods may require disclosure of diluted
earnings which was not required under previous accounting standards since the
dilution was less than 3%. The Company has determined that basic and diluted
earnings per share (as defined by SFAS No. 128) would be the same as primary and
fully diluted earnings per share, respectively, disclosed for the three months
ended March 31, 1997 and 1996.

                                                                              13

ITEM 5.  OTHER INFORMATION

     On April 10, 1997, the Company announced that its Board of Directors
authorized the purchase of up to two million shares of the Company's common
stock, or about 7% of shares outstanding. These purchases are in addition to the
three million share program (adjusted for the March 1997 three-for-two stock
split) announced in May 1996, which was completed in April 1997.

     On May 14, 1997, the Company acquired producing properties and undeveloped
acreage in Oklahoma, Kansas and Texas for $39.5 million from a subsidiary of
Burlington Resources Inc. The purchase price will be reduced by net revenues
from the effective date of April 1, 1997 through the May 14 closing date. The
properties are primarily operated interests. The Company's internal engineers
estimate related proved reserves to be 36.5 billion cubic feet equivalent of
natural gas, of which more than 97% is gas. Current daily production from the
acquired interests averages 5.5 million cubic feet of gas equivalent.
Approximately 30% of the purchase price is attributable to 124 square miles
(79,500 net acres) of undeveloped acreage primarily located in Texas County,
Oklahoma. The Company funded the acquisition with bank debt and cash flow from
operations.

     The Company understands that the Initial Purchasers propose to make an
offering of the Securities on the terms and in the manner set forth herein and
agrees that the Initial Purchasers may resell, subject to the conditions set

Purchasers") at any time after the date of this Agreement.  The Securities are
to be offered and sold through the Initial Purchasers without being registered
under the Securities Act of 1933, as amended (the "1933 Act"), in reliance upon
exemptions therefrom.  Pursuant to the terms of the Securities and the
Indenture, investors that acquire Securities may only resell or otherwise
transfer such Securities if such Securities are hereafter registered under the
1933 Act or if an exemption from the registration requirements of the 1933 Act
is available (including the exemption afforded by Rule 144A ("Rule 144A") or
Regulation S ("Regulation S") of the rules and regulations promulgated under the
1933 Act by the Securities and Exchange Commission (the "Commission")).

     The Company has prepared and delivered to each Initial Purchaser copies of
a preliminary offering memorandum dated March 14, 1997 (the "Preliminary
Offering Memorandum") and has prepared and will deliver to each Initial
Purchaser, on the date hereof or the next succeeding business day, copies of a
final offering memorandum dated March 26, 1997 (the "Final Offering
Memorandum"), each for use by such Initial Purchaser in connection with its
solicitation of purchases of, or offering of, the Securities. "Offering
Memorandum" means, with respect to any date or time referred to in this
Agreement, the most recent offering memorandum (whether the Preliminary Offering
Memorandum or the Final Offering Memorandum, or any amendment or supplement to
either such document), including exhibits thereto and any documents incorporated
therein by reference, which has been prepared and delivered by the Company to
the Initial Purchasers in connection with their solicitation of purchases of, or
offering of, the Securities.

     At the Closing Time, and as a condition to the obligations of the Initial
Purchasers hereunder, the Company and each of the Initial Purchasers will enter
into a Registration Rights Agreement (the "Registration Rights Agreement"),
substantially in the form attached hereto as Exhibit A.  Pursuant to the
Registration Rights Agreement, the Company will agree, among other things, to
use its reasonable best efforts to file with, and cause to be declared effective
by, the Commission a registration statement with respect to a registered
exchange offer under the 1933 Act, relating to the offer to exchange the
Securities for like respective principal amount of debt securities of the
Company identical in all material respects to the Securities.

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the Offering
Memorandum (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
are incorporated by reference in the Offering Memorandum; and all references in
this Agreement to amendments or supplements to the Offering Memorandum shall be
deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934 (the "1934 Act") which is incorporated by reference in the

     included in the Offering Memorandum present fairly in all material respects
     the information shown therein and have been compiled on a basis consistent
     with that of the audited financial statements included in the Offering
     Memorandum. The column entitled "Pro Forma, As Adjusted," in the section of

                    (xiii) Description of the Securities and the Indenture.  
                           ----------------------------------------------- 
     The Securities and the Indenture will conform in all material respects to
     the respective statements relating thereto contained in the Offering
     Memorandum and will be in substantially the respective forms previously
     delivered to the Initial Purchasers.

                    (xiv)  Absence of Defaults and Conflicts.  Neither the 
                           ---------------------------------  
     Company nor any of its subsidiaries is in violation of its charter or by-
     laws or in default in the performance or observance of any obligation,
     agreement, covenant or condition contained in any contract, indenture,
     mortgage, deed of trust, loan or credit agreement, note, lease or other
     agreement or instrument to which the Company or any of its subsidiaries is
     a party or by which any of them may be bound, or to which any of the
     property or assets of the Company or any of its subsidiaries is subject
     (collectively, "Agreements and Instruments") except for such defaults that
     would not result in a Material Adverse Effect; and the execution, delivery
     and performance of this Agreement, the Registration Rights Agreement, the
     Indenture and the Securities and any other agreement or instrument entered
     into or issued or to be entered into or issued by the Company in connection
     with the transactions contemplated hereby or thereby or in the Offering
     Memorandum and the consummation of the transactions contemplated herein and
     in the Offering Memorandum (including the issuance and sale of the
     Securities and the use of the proceeds from the sale of the Securities as
     described in the Offering Memorandum under the caption "Use of Proceeds")
     and compliance by the Company with its obligations hereunder have been duly
     authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or a Repayment Event
     (as defined below) under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any property or assets of the Company or
     any of its subsidiaries pursuant to, the Agreements and Instruments except
     for such conflicts, breaches or defaults or liens, charges or encumbrances
     that, singly or in the aggregate, would not result in a Material Adverse
     Effect, nor will such action result in any violation of any applicable law,
     statute, rule, regulation, judgment, order, writ or decree of any
     government, government instrumentality or court, domestic or foreign,
     having jurisdiction over the Company or any of its subsidiaries or any of
     their assets or properties, which violation would result in a Material
     Adverse Effect, nor will such action result in any violation of the
     provisions of the charter or by-laws of the Company or any of its
     subsidiaries. No event of default exists under any contract, indenture,
     mortgage, loan agreement, note, lease or other agreement or instrument
     constituting Senior Indebtedness (as defined in the Indenture). As used
     herein, a "Repayment Event" means any event or condition which gives the
     holder of any note, debenture or other evidence of indebtedness (or any
     person acting on such holder's behalf) the right to require the repurchase,
     redemption or repayment of all or a portion of such indebtedness by the
     Company or any of its subsidiaries.

                    (xv)   Absence of Labor Dispute.  No labor dispute with the

     knowledge of the Company, is imminent, and the Company is not aware of any
     existing or imminent labor disturbance by the employees of any of its or
     any of its subsidiaries' principal suppliers, manufacturers,

                                       6
<PAGE>
 
     customers or contractors, which, in either case, may reasonably be expected
     to result in a Material Adverse Effect.

                    (xvi)   Absence of Proceedings.  Except as disclosed in the 
                            ----------------------       
     Offering Memorandum, there is no action, suit, proceeding, inquiry or
     investigation before or by any court or governmental agency or body,
     domestic or foreign, now pending, or, to the knowledge of the Company,
     threatened, against or affecting the Company or any subsidiary thereof
     which might reasonably be expected to result in a Material Adverse Effect,
     or which might reasonably be expected to materially and adversely affect
     the properties or assets of the Company or any of its subsidiaries or the
     consummation of this Agreement, the Indenture, the Securities or the
     Registration Rights Agreement or the performance by the Company of its
     obligations hereunder. The aggregate of all pending legal or governmental
     proceedings to which the Company or any subsidiary thereof is a party or of
     which any of their respective property or assets is the subject which are
     not described in the Offering Memorandum, including ordinary routine
     litigation incidental to the business, could not reasonably be expected to
     result in a Material Adverse Effect.

                    (xvii)  Possession of Intellectual Property.  The Company 
                            -----------------------------------  
     and its subsidiaries own or possess, or can acquire on reasonable terms,
     adequate patents, patent rights, licenses, inventions, copyrights, know-how
     (including trade secrets and other unpatented and/or unpatentable
     proprietary or confidential information, systems or procedures),
     trademarks, service marks, trade names or other intellectual property
     (collectively, "Intellectual Property") necessary to carry on the business
     now operated by them, and neither the Company nor any of its subsidiaries
     has received any notice or is otherwise aware of any infringement of or
     conflict with asserted rights of others with respect to any Intellectual
     Property or of any facts or circumstances which would render any
     Intellectual Property invalid or inadequate to protect the interest of the
     Company or any of its subsidiaries therein, and which infringement or
     conflict (if the subject of any unfavorable decision, ruling or finding) or
     invalidity or inadequacy, singly or in the aggregate, would result in a
     Material Adverse Effect.

                    (xviii) Absence of Further Requirements.  No filing with, or
                            -------------------------------

     qualification or decree of, any court or governmental authority or agency
     is necessary or required for the performance by the Company of its
     obligations hereunder, in connection with the offering, issuance or sale of
     the Securities hereunder or the consummation of the transactions
     contemplated by this Agreement or the Registration Rights Agreement, except
     such as may be required under state securities laws, and, in the case of
     the performance of the Company's obligations under the Registration Rights
     Agreement, such as may be required under the federal securities laws.

                    (xix)   Possession of Licenses and Permits.  The Company 
                            ----------------------------------   
     and its subsidiaries possess such certificates, permits, licenses,
     approvals, consents and other authorizations (collectively, "Governmental
     Licenses") issued by the appropriate federal, state, local or foreign
     regulatory agencies or bodies necessary to conduct the business now

                                       7
<PAGE>
 
     conducted by them; the Company and its subsidiaries are in compliance with
     the terms and conditions of all such Governmental Licenses, except where
     the failure so to comply would not, singly or in the aggregate, have a
     Material Adverse Effect; all of the Governmental Licenses are valid and in
     full force and effect, except where the invalidity of such Governmental
     Licenses or the failure of such Governmental Licenses to be in full force
     and effect would not have a Material Adverse Effect; and neither the
     Company nor any of its subsidiaries has received any notice of proceedings
     relating to the revocation or modification of any such Governmental
     Licenses which, singly or in the aggregate, if the subject of an
     unfavorable decision, ruling or finding, would result in a Material Adverse
     Effect.

                    (xx)   Title to Property.  The Company and its subsidiaries
                           ----------------- 
      have good and defensible title to their producing oil and gas properties,
     and any gas gathering properties that it owns, free and clear of all liens,
     encumbrances and defects, except (a) those described in the Offering
     Memorandum, (b) liens securing taxes and other governmental charges, or
     claims of materialmen, mechanics and similar persons, not yet due and
     payable, (c) liens and encumbrances under operating agreements, unitization
     and pooling agreements, and gas sales contracts, securing payment of
     amounts not yet due and payable and of a scope and nature customary in the
     oil and gas industry and (d) liens, encumbrances and defects that do not in
     the aggregate materially affect the value of such oil and gas properties or
     gas gathering properties or materially interfere with the use made or
     proposed to be made of such properties by the Company and its subsidiaries.
     Except to the extent described in the Offering Memorandum, the oil, gas and
     mineral leases, coal methane leases, options to lease, drilling concessions
     or other property interests therein held by the Company and its
     subsidiaries reflect in all material respects the right of the Company and
     its subsidiaries, as the case may be, to explore or receive production from
     the undeveloped properties described in the Offering Memorandum, and the
     care taken by the Company and its subsidiaries with respect to acquiring or
     otherwise procuring such leases, options to lease, drilling concessions and
     other property interests was generally consistent with standard industry
     practices for acquiring or procuring leases and interests therein to
     explore such for hydrocarbons. All other leases and subleases material to
     the business of the Company and its subsidiaries, considered as one
     enterprise, and under which the Company or any of its subsidiaries holds
     properties described in the Offering Memorandum are in full force and
     effect, and neither the Company nor any of its subsidiaries has actual
     notice of any material claim of any sort that has been asserted by anyone
     adverse to the rights of the Company or any subsidiary under any of such
     leases or subleases, or affecting or questioning the rights of the Company
     or such subsidiary to the continued possession of the leased or subleased

Memorandum by preparing and furnishing (in reasonable number) to each Initial
Purchaser an amendment or amendments of, or a supplement or supplements to, the
Final Offering Memorandum (in form and substance satisfactory in the reasonable
opinion of counsel for the Initial Purchasers) so that, as so amended or
supplemented, the Final Offering Memorandum will not include an untrue statement
of a material fact or omit to state a material fact necessary in order to make

     ("Institutional Accredited Investors") or (C) non-U.S. persons

                                       16

     outside the United States to whom the offeror or seller reasonably believes
     offers and sales of the Securities may be made in reliance upon Regulation
     S under the 1933 Act.

               (ii)   No General Solicitation.  The Securities will be offered 
                      -----------------------         
     by the Initial Purchasers only by approaching prospective Subsequent
     Purchasers on an individual basis. No general solicitation or general
     advertising (within the meaning of Rule 502(c) under the 1933 Act) will be
     used in the United States in connection with the offering of the
     Securities.

               (iii)  Purchases by Non-Bank Fiduciaries.  In the case of a 
                      ---------------------------------   
     non-bank Subsequent Purchaser of a Security acting as a fiduciary for one
     or more third parties, in connection with an offer and sale to such
     purchaser pursuant to clause (a) (i) above, each third party shall, in the
     judgment of the applicable Initial Purchaser, be an Institutional
     Accredited Investor or a Qualified Institutional Buyer or a non-U.S. person
     outside the United States.

               (iv)   Subsequent Purchaser Notification.  Each Initial Purchaser
                      ---------------------------------  
     will take reasonable steps to inform, and cause each of its U.S. affiliates
     to take reasonable steps to inform, persons acquiring Securities from such
     Initial Purchaser or affiliate, as the case may be, in the United States
     that the Securities (A) have not been and will not be registered under the
     1933 Act, (B) are being sold to them without registration under the 1933
     Act in reliance on Rule 144A or in accordance with another exemption from
     registration under the 1933 Act, as the case may be, and (C) may not be
     offered, sold or otherwise transferred except (1) to the Company, (2)
     outside the United States in accordance with Rule 904 of Regulation S, or
     (3) inside the United States in accordance with (x) Rule 144A to a person
     whom the seller reasonably believes is a Qualified Institutional Buyer that
     is purchasing such Securities for its own account or for the account of a
     Qualified Institutional Buyer to whom notice is given that the offer, sale
     or transfer is being made in reliance on Rule 144A or (y) the exemption
     from registration under the 1933 Act provided by Rule 144, if available.

               (v)    Restrictions on Transfer.  The transfer restrictions and 
                      ------------------------       
     the other provisions set forth in Section 2.07 of the Indenture, including
     the legend required thereby, shall apply to the Securities except as
     otherwise agreed by the Company and the Initial Purchasers. Following the
     sale of the Securities by the Initial Purchasers to Subsequent Purchasers
     pursuant to the terms hereof, the Initial Purchasers shall not, in their
     capacities as Initial Purchasers, be liable or responsible to the Company
     for any losses, damages or liabilities suffered or incurred by the Company,
     including any losses, damages or liabilities under the 1933 Act, arising
     from or relating to any subsequent resale or transfer of any Security.

               (vi)   Delivery of Offering Memorandum.  Each Initial Purchaser 
                      -------------------------------    
     will deliver to each purchaser of the Securities from such Initial
     Purchaser, in connection with its original distribution of the Securities,
     a copy of the Offering Memorandum, as amended and supplemented at the date
     of such delivery.

                                       17
<PAGE>
 
          (b)  Covenants of the Company.  The Company covenants with each
Initial Purchaser as follows:

               (i)    Due Diligence.  In connection with the original 
                      -------------                                
     distribution of the Securities, the Company agrees that, prior to any offer
     or resale of the Securities by the Initial Purchasers, the Initial
     Purchasers and counsel for the Initial Purchasers shall have the right to
     make reasonable inquiries into the business of the Company and its
     subsidiaries. The Company also agrees to provide answers to each
     prospective Subsequent Purchaser of Securities who so requests concerning
     the Company and its subsidiaries (to the extent that such information is
     available or can be acquired and made available to prospective Subsequent
     Purchasers without unreasonable effort or expense and to the extent that
     officers of the Company determine, in their reasonable judgment, such
     information need not be kept confidential and the provision thereof is not
     prohibited by applicable law) and the terms and conditions of the offering
     of the Securities, as provided in the Offering Memorandum.

               (ii)   Integration.  The Company agrees that it will not and will
                      -----------      
     cause its affiliates not to make any offer or sale of any class of
     securities of the Company if, as a result of the doctrine of "integration"
     referred to in Rule 502 under the 1933 Act, such offer or sale would render
     invalid (for the purpose of (A) the sale of the Securities by the Company
     to the Initial Purchasers, (B) the resale of the Securities by the Initial
     Purchasers to Subsequent Purchasers or (C) the resale of the Securities by
     such Subsequent Purchasers to others) the exemption from the registration
     requirements of the 1933 Act provided by Section 4(2) thereof or Regulation
     thereunder or by Rule 144A or otherwise.

               (iii)  Rule 144A Information.  The Company agrees that, in order 
                      ---------------------  
     to render the Securities eligible for resale pursuant to Rule 144A under
     the 1933 Act, while any of the Securities remain outstanding, it will make
     available, upon request, to any holder of Securities or prospective
     purchasers of Securities the information specified in Rule 144A(d)(4),
     unless the Company furnishes information to the Commission pursuant to
     Section 13 or 15(d) of the 1934 Act (such information, whether made
     available to holders or prospective purchasers or furnished to the
     Commission, is herein referred to as "Additional Information").

               (iv)   Restriction on Repurchases.  Until the expiration of two 
                      -------------------------- 
     years after the original issuance of the Securities, the Company will not,
     and will cause its affiliates not to, purchase or agree to purchase or
     otherwise acquire any Securities which are "restricted securities" (as such
     term is defined under Rule 144(a)(3) under the 1933 Act), whether as
     beneficial owner or otherwise (except as agent acting as a securities
     broker on behalf of and for the account of customers in the ordinary course
     of business in unsolicited broker's transactions) unless, immediately upon
     any such purchase, the Company or any Affiliate shall submit such
     Securities to the Trustee for cancellation.

          (c)  Selling Restrictions for Offers and Sales Outside the United
States. Each Initial Purchaser understands that the Securities have not been and
will not be registered under the 1933 Act and may not be offered or sold within
the United States or to, or for the account or benefit

                                       18
<PAGE>
 
of, U.S. persons except in accordance with Regulation S under the 1933 Act or
pursuant to an exemption from the registration requirements of the 1933 Act.
Each Initial Purchaser represents and agrees, that except as permitted by
Section 6(a) above, it has offered and sold Securities and will offer and sell
Securities (i) as part of their distribution at any time and (ii) otherwise
until forty days after the later of the date upon which the offering of the
Securities commences and the Closing Time, only in accordance with Rule 903 of
Regulation S or Rule 144A under the 1933 Act. Accordingly, neither the Initial
Purchasers, their affiliates nor any persons acting on their behalf have engaged
or will engage in any directed selling efforts with respect to Securities, and
the Initial Purchasers, their affiliates and any person acting on their behalf
have complied and will comply with the offering restriction requirements of
Regulation S. Each Initial Purchaser agrees that at or prior to confirmation of
a sale of Securities (other than a sale of Securities pursuant to Rule 144A), it
will have sent to each distributor, dealer or person receiving a selling
concession, fee or other remuneration that purchases Securities from it or
through it during the restricted period a confirmation or notice to
substantially the following effect:

          "The Securities covered hereby have not been registered
          under the United States Securities Act of 1933 (the
          "Securities Act") and may not be offered or sold within the
          United States or to or for the account or benefit of U.S.
          persons (i) as part of their distribution at any time and
          (ii) otherwise until forty days after the later of the date
          upon which the offering of the Securities commenced and the
          date of closing, except in either case in accordance with
          Regulation S or Rule 144A under the Securities Act. Terms
          used above have the meaning given to them by Regulation S."

Terms used in the above paragraph have the meanings given to them by Regulation
S.

     Each Initial Purchaser severally represents and agrees that it has not
entered and will not enter into any contractual arrangements with respect to the
distribution of the Securities, except with its affiliates or with the prior
written consent of the Company.

Section 7.   Indemnification.

          (a)  Indemnification of Initial Purchasers.  The Company agrees to
indemnify and hold harmless each Initial Purchaser and each person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act as follows:

               (i)    against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Offering Memorandum or the Final Offering Memorandum (or any amendment or
     supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

                                       19
<PAGE>
 
               (ii)   against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, to the extent of the aggregate amount paid
     in settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     7(d) below) any such settlement is effected with the written consent of the
     Company; and

               (iii)  against any and all expense whatsoever, as incurred
     (including the fees and disbursements of counsel chosen by Merrill Lynch),
     reasonably incurred in investigating, preparing or defending against any
     litigation, or any investigation or proceeding by any governmental agency
     or body, commenced or threatened, or any claim whatsoever based upon any
     such untrue statement or omission, or any such alleged untrue statement or
     omission, to the extent that any such expense is not paid under (i) or (ii)
     above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Initial Purchaser through Merrill Lynch expressly for use in the Offering
Memorandum (or any amendment thereto) and provided, further, that this indemnity
agreement with respect to any Preliminary Offering Memorandum shall not inure to
the benefit of any Initial Purchaser from whom the person asserting any such
losses, liabilities, claims, damages or expenses purchased Securities, or any
person controlling such Initial Purchaser, if a copy of the Offering Memorandum,
as then amended or supplemented, was not sent or given by or on behalf of the
Initial Purchaser to such person at or prior to the written confirmation of the
sale of such Securities to such person and if the Offering Memorandum, as so
amended or supplemented, would have corrected any untrue statement or omission,
or alleged untrue statement or omission, giving rise to such loss, liability,
claim, damage or expense (provided the Company has delivered the Offering
Memorandum, as then amended or supplemented, to the several Initial Purchasers
in requisite quantity on a timely basis to permit such delivery or sending).

          (b)  Indemnification of Company and Directors.  Each Initial Purchaser
severally agrees to indemnify and hold harmless the Company, its directors, and
each person, if any, who controls the Company within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act against any and all loss,
liability, claim, damage and expense described in the indemnity contained in
subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Offering Memorandum in reliance upon and in conformity with written information
furnished to the Company by such Initial Purchaser through Merrill Lynch
expressly for use in the Offering Memorandum.

          (c)  Actions against Parties; Notification.  Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not

                                       20
<PAGE>
 
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 7(a) above,
counsel to the indemnified parties shall be selected by Merrill Lynch, and, in
the case of parties indemnified pursuant to Section 7(b) above, counsel to the
indemnified parties shall be selected by the Company. Notwithstanding the
foregoing, in case any action or proceeding shall be instituted and the
indemnified party shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate therein, and,
after written notice from the indemnifying party to such indemnified party, to
assume the defense thereof with counsel of its choice reasonably acceptable to
the indemnified parties in such action. Notwithstanding the election of the
indemnifying party to assume defense of such action or proceeding, the
indemnified party shall have the right, at its own expense, to employ one
additional firm as separate counsel and to participate in the defense of the
action or proceeding; provided that the indemnifying party shall pay the
reasonable fees and expenses of such separate counsel reasonably satisfactory to
the indemnifying party if (i) the indemnifying party shall have failed to employ
counsel to represent the indemnified party in a reasonably timely manner or (ii)
the defendants in any such action or proceeding include both the indemnified
party and the indemnifying party and counsel to the indemnified party shall have
concluded and notified the indemnifying party that in its reasonable judgment
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 7 or Section 8 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim 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 any
indemnified party.

          (d)  Settlement without Consent if Failure to Reimburse.  If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 7(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

                                       21

Section 8.   Contribution.

     If the indemnification provided for in Section 7 hereof is for any reason
unavailable to or insufficient to hold harmless an indemnified party in respect
of any losses, liabilities, claims, damages or expenses referred to therein,
then each indemnifying party shall contribute to the aggregate amount of such
losses, liabilities, claims, damages and expenses incurred by such indemnified
party, as incurred, (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Initial
Purchasers on the other hand from the offering of the Securities pursuant to
this Agreement or (ii) if the allocation provided by clause (i) is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and of the Initial Purchasers on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received by the Company on the one hand and the
Initial Purchasers on the other hand in connection with the offering of the
Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total initial purchasers' discount received by the Initial
Purchasers, bear to the aggregate initial offering price of the Securities.

     The relative fault of the Company on the one hand and the Initial
Purchasers on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Initial Purchasers and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

     The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation (even if the Initial Purchasers 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 above in this Section 8. The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 8 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 8, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities purchased by it exceeds the amount of any
damages which such Initial Purchaser has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.

                                       22
<PAGE>
 
     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 8, each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such Initial
Purchaser, and each director of the Company, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as the Company.
The Initial Purchasers' respective obligations to contribute pursuant to this
Section 8 are several in proportion to the principal amount of Securities set
forth opposite their respective names in Schedule A hereto and not joint.

Section 9.   Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement
or in certificates of officers of the Company submitted pursuant hereto, shall
remain operative and in full force and effect, regardless of any investigation
made by or on behalf of any Initial Purchaser or controlling person, or by or on
behalf of the Company, and shall survive delivery of the Securities to the
Initial Purchasers.

Section 10.  Termination of Agreement.

          (a)  Termination; General.  The Representatives may terminate this
Agreement, by notice to the Company, at any time at or prior to the Closing Time
(i) if there has been, since the time of execution of this Agreement or since
the respective dates as of which information is given in the Offering
Memorandum, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company and its subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there has occurred any
material adverse change in the financial markets in the United States or
elsewhere, any outbreak of hostilities or escalation thereof or other calamity
or crisis or any change or development involving a prospective change in
national or international political, financial or economic conditions, in each
case the effect of which is such as to make it, in the judgment of the
Representatives, impracticable to market the Securities or to enforce contracts
for the sale of the Securities, or (iii) if trading in any securities of the
Company has been suspended or limited by the Commission or New York Stock
Exchange, or if trading generally on the American Stock Exchange or the New York
Stock Exchange or in the NASDAQ National Market System has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Commission, the National Association of Securities Dealers,
Inc. or any other governmental authority, or (iv) if a banking moratorium has
been declared by either Federal, New York or Texas authorities.

          (b)  Liabilities.  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4

                                       23
<PAGE>
 
hereof, and provided further that Sections 1, 7 and 8 shall survive such
termination and remain in full force and effect.

Section 11.  Default by One or More of the Initial Purchasers.

     If one or more of the Initial Purchasers shall fail at the Closing Time to
purchase the Securities which it or they are obligated to purchase under this
Agreement (the "Defaulted Securities"), the Representatives shall have the
right, within 24 hours thereafter, to make arrangements for one or more of the
non-defaulting Initial Purchasers, or any other Initial Purchasers, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set forth:  if, however, the
Representatives shall not have completed such arrangements within such 24-hour
period, then:

          (a)  if the number of Defaulted Securities does not exceed 10% of the
aggregate principal amount of the Securities to be purchased hereunder, each of
the non-defaulting Initial Purchasers shall be obligated, severally and not
jointly, to purchase the full amount thereof in the proportions that their
respective underwriting obligations hereunder bear to the underwriting
obligations of all non-defaulting Initial Purchasers, or

          (b)  if the number of Defaulted Securities exceeds 10% of the
aggregate principal amount of the Securities to be purchased hereunder, this
Agreement shall terminate without liability on the part of any non-defaulting
Initial Purchaser.

     No action taken pursuant to this Section shall relieve any defaulting
Initial Purchaser from liability in respect of its default.

     In the event of any such default which does not result in a termination of
this Agreement, either the Representatives or the Company shall have the right
to postpone the Closing Time for a period not exceeding seven days in order to
effect any required changes in the Offering Memorandum or in any other documents
or arrangements.  As used herein, the term "Initial Purchaser" includes any
person substituted for an Initial Purchaser under this Section 11.

Section 12.  Notices.

     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication. Notices to the Initial Purchasers shall be directed
to the Representatives at North Tower, World Financial Center, New York, New
York 10281-1201, attention of Wood Steinberg, Vice President; notices to the
Company shall be directed to them at 810 Houston Street, Suite 2000, Fort Worth,
Texas 76102, attention of Louis G. Baldwin.

Section 13.  Parties.

     This Agreement shall inure to the benefit of and be binding upon the
Initial Purchasers, the Company and their respective successors. Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any person, firm or corporation, other than the Initial Purchasers, the
Company and their respective successors and the controlling persons and officers
and directors referred to in Sections 7 and 8 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision herein contained. This Agreement and
all conditions and provisions hereof are intended to be for the sole and
exclusive benefit of the Initial Purchasers, the Company and their respective
successors, and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm or
corporation. No purchaser of Securities from any Initial Purchaser shall be
deemed to be a successor by reason merely of such purchase.

Section 14.  GOVERNING LAW AND TIME.

     THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED

               (a) Exchange Offer Registration. To the extent not prohibited by
                   ---------------------------
law (including, without limitation, any applicable interpretation of the staff
of the SEC), the Company shall use its reasonable best efforts (i) to file
within 45 days after the Closing Date an Exchange Offer Registration Statement
covering the offer by the Company to the Holders to exchange all of the
Registrable Securities (except Registrable Securities held by an Initial
Purchaser and acquired directly from the Company if such Initial Purchaser is
not permitted, in the reasonable opinion of counsel to the Initial Purchasers,
pursuant to applicable law or SEC interpretation, to participate in the Exchange
Offer) for Exchange Securities, (ii) to cause such Exchange Offer Registration
Statement to be declared effective by the SEC within 105 days after the Closing
Date, (iii) to cause such Exchange Offer Registration Statement to remain
effective until the closing of the Exchange Offer and (iv) to consummate the
Exchange Offer within 180 days following the Closing Date. The Exchange
Securities will be issued under the Indenture. Upon the effectiveness of the
Exchange Offer Registration Statement, the Company shall promptly commence the
Exchange Offer, it being the objective of such Exchange Offer to enable each
Holder (other than Participating Broker-Dealers (as defined in Section 3(f)
hereof) and broker-dealers who purchased Debt Securities directly from the
Company to resell pursuant to Rule 144A or any other available exemption under
the 1933 Act) eligible and electing to exchange Registrable Securities for
Exchange Securities (assuming that such Holder is not an affiliate of the
Company, acquires the Exchange Securities in the ordinary course of such
Holder's business and has no arrangements or understandings with any person to
participate in the distribution (within the meaning of the 1933 Act) of Exchange
Securities) to trade or sell such Exchange Securities from and after their
receipt without any limitations or restrictions under the 1933 Act and without
material restrictions under the securities laws of a substantial proportion of
the several states of the United States.

     In connection with the Exchange Offer, the Company shall:

                    (A)  mail to each Holder a copy of the Prospectus forming
          part of the Exchange Offer Registration Statement, together with an
          appropriate letter of transmittal and related documents;

                    (B)  keep the Exchange Offer open for not less than 30 days
          after the date notice thereof is mailed to the Holders (or longer if
          required by applicable law);

                    (C)  use the services of the Depositary for the Exchange
          Offer;

                    (D)  permit Holders to withdraw tendered Registrable
          Securities at any time prior to the close of business, New York City
          time, on the last business day on which the Exchange Offer shall
          remain open, by sending to the institution specified

                                      -5-
<PAGE>
 
          in the notice, a telegram, telex, facsimile transmission or letter
          setting forth the name of such Holder, the principal amount of
          Registrable Securities delivered for exchange and a statement that
          such Holder is withdrawing his election to have such Debt Securities
          exchanged; and

                    (E)  otherwise comply in all respects with all applicable
          laws relating to the Exchange Offer.

               As soon as practicable after the close of the Exchange Offer, the
Company shall:

                         (x)  accept for exchange Registrable Securities duly
          tendered and not validly withdrawn pursuant to the Exchange Offer in
          accordance with the terms of the Exchange Offer Registration Statement
          and the letter of transmittal which is an exhibit thereto;

                         (y)  deliver, or cause to be delivered, to the Trustee
          for cancellation all Registrable Securities so accepted for exchange
          by the Company; and

                         (z)  cause the Trustee promptly to authenticate and
          deliver Exchange Securities to each Holder of Registrable Securities
          equal in amount to the Registrable Securities of such Holder so
          accepted for exchange.

     Interest on each Exchange Security will accrue from the last date on which
interest was paid or duly provided for on the Registrable Securities surrendered
in exchange therefor or, if no interest has been paid on the Registrable
Securities, from April 2, 1997. The Exchange Offer shall not be subject to any
conditions, other than (1) that the Exchange Offer, or the making of any
exchange by a Holder, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (2) that no action or proceeding shall
have been instituted or threatened in any court or by or before any governmental
agency or body with respect to the Exchange Offer, (3) that there shall not have
been adopted or enacted any law, statute, rule or regulation prohibiting or
limiting the Exchange Offer, (4) that there shall not have been declared by
United States federal or Texas or New York state authorities a banking
moratorium, (5) that trading on the New York Stock Exchange or generally in the
United States over-the-counter market shall not have been suspended by order of
the SEC or any other governmental authority and (6) such other conditions as may
be reasonably acceptable to Merrill Lynch which, in the Company's judgment,
would reasonably be expected to impair the ability of the Company to proceed
with the Exchange Offer. In addition, each Holder of Registrable Securities
(other than Participating Broker-Dealers) who wishes to exchange such
Registrable Securities for Exchange Securities in the Exchange Offer will be
required to represent that (I) it is not an affiliate of the Company, (II) any
Exchange Securities to be received by it were acquired in the ordinary course of
business and (III) it is not engaged in, and does not intend to engage in, and
has no arrangement or understanding with any person to participate in, the
distribution (within the meaning of the 1933 Act) of the Exchange Securities.
Each Participating Broker-Dealer shall be required to make such representations
as, in the reasonable judgment of the Company, may be necessary under applicable

                                      -6-
<PAGE>
 
SEC rules, regulations or interpretations or customary in connection with
similar exchange offers. Each Holder (including Participating Broker-Dealers)
shall be required to make such other representations as may be reasonably
necessary under applicable SEC rules, regulations or interpretations to render
the use of Form S-4 or another appropriate form under the 1933 Act available and
will be required to agree to comply with their agreements and covenants set
forth in this Agreement. The Exchange Offer shall be subject to the further
condition that no stop order, injunction or similar order shall have been issued
or obtained by the SEC or any state securities authority suspending the
effectiveness of the Exchange Offer Registration Statement and no proceedings
shall have been initiated or, to the knowledge of the Company, threatened for
that purpose. To the extent permitted by law, the Company shall, upon request of
Merrill Lynch, inform the Initial Purchasers of the names and addresses of the
Holders to whom the Exchange Offer is made, and the Initial Purchasers shall
have the right to, and, if requested by the Company, shall, contact such Holders
and otherwise facilitate the tender of Registrable Securities in the Exchange
Offer.

     Prior to effectiveness of the Exchange Offer Registration Statement, the
Company shall, if requested by the staff of the SEC, provide a supplemental
letter to the SEC (aa) stating that the Company is registering the Exchange
Offer in reliance on the position of the SEC enunciated in Exxon Capital
Holdings Corporation (available May 13, 1988) and Morgan Stanley and Co., Inc.
(available June 5, 1991) and (bb) including a representation that the Company
has not entered into any arrangement or understanding with any Person to
distribute the Exchange Securities and that, to the best of the Company's
information and belief, each Holder participating in the Exchange Offer is
acquiring the Exchange Securities in its ordinary course of business and has no
arrangement or understanding with any Person to participate in the distribution
of the Exchange Securities received in the Exchange Offer.

     If in the reasonable opinion of counsel to the Company there is a question
as to whether the Exchange Offer is permitted by applicable law, the Company
hereby agrees to seek a no-action letter or other favorable decision from the
SEC allowing the Company to consummate the Exchange Offer. The Company hereby
agrees to pursue the issuance of such a decision to the SEC staff level, but
shall not be required to take action to effect a change of stated or recognized
SEC policy.  The Company hereby agrees, however, to (xx) participate in
telephonic conferences with the SEC and the staff of the SEC, (yy) deliver to
the staff of the SEC an analysis prepared by counsel to the Company setting
forth the legal bases, if any, upon which such counsel has concluded that the
Exchange Offer should be permitted and (zzz) diligently pursue a resolution
(which need not be favorable) by the staff of the SEC of such submission.

          (b)  Shelf Registration. (i) If, because of any change in law or
               ------------------                                         
applicable interpretations thereof by the staff of the SEC, the Company is not
permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof,
or (ii) if for any other reason the Exchange Offer Registration Statement is not
declared effective within 105 days after the Closing Date or the Exchange Offer
is not consummated within 180 days after the Closing Date, or (iii) upon the
request of Merrill Lynch (but only with respect to any Registrable Securities
which the Initial Purchasers acquired directly from the Company) following the
consummation of the Exchange Offer if any of the Initial Purchasers shall hold
Registrable Securities which such Initial Purchaser acquired directly

                                      -7-
<PAGE>
 
from the Company and if such Initial Purchaser is not permitted, in the
reasonable opinion of counsel to the Initial Purchasers, pursuant to applicable
law or applicable interpretation of the staff of the SEC to participate in the
Exchange Offer, then the Company shall, at its cost:

                    (A)  in the event clause (i) or (ii) is applicable, as
          promptly as practicable (but in no event (x) more than 30 days from
          the date on which the Company determined that it is not permitted to
          effect the Exchange Offer as contemplated by Section 2(a) hereof in
          the case of clause (i) or (y) on the 135th day after the Closing Date
          in the case of clause (ii)), file with the SEC a Shelf Registration
          Statement relating to the offer and sale of the Registrable Securities
          (other than Registrable Securities owned by Holders who have elected
          not to include such Registrable Securities in such Shelf Registration
          Statement or who have not complied with their obligations under the
          penultimate paragraph of Section 3 hereof or under the penultimate
          sentence of this Section 2(b)) by the Holders from time to time in
          accordance with the methods of distribution elected by the Majority
          Holders of such Registrable Securities and set forth in such Shelf
          Registration Statement, and use its reasonable best efforts to cause
          such Shelf Registration Statement to be declared effective by the SEC
          by the 180th day after the Closing Date. In the event that the Company
          is required to file a Purchaser Shelf Registration Statement upon the
          request of Merrill Lynch pursuant to clause (iii) above, the Company
          shall use its reasonable best efforts (unless clause (i) or (ii) above
          is applicable) to file and have declared effective by the SEC an
          Exchange Offer Registration Statement pursuant to Section 2(a) with
          respect to all Registrable Securities (other than Registrable
          Securities acquired directly from the Company and held by the Initial
          Purchasers) and use its reasonable best efforts to file, promptly
          after any such request from Merrill Lynch, and have declared
          effective, a Purchaser Shelf Registration Statement (which may be a
          combined Registration Statement with the Exchange Offer Registration
          Statement or, if clause (i) or (ii) above is applicable, a combined
          Registration Statement with the Shelf Registration Statement);

                    (B)  use its reasonable best efforts to keep the relevant
          Subject Registration Statement continuously effective in order to
          permit the Prospectus forming part thereof to be usable by Holders for
          a period of two years from the date a Shelf Registration Statement is
          declared effective by the SEC (or, in the case of a Purchaser Shelf
          Registration Statement, one year from the date a Purchaser Shelf
          Registration Statement is declared effective) or in each case such
          shorter period which will terminate when all of the Registrable
          Securities covered by the relevant Subject Registration Statement have
          been sold pursuant to such Subject Registration Statement or otherwise
          are no longer Registrable Securities; and

                    (C)  notwithstanding any other provisions hereof, use its
          reasonable best efforts to ensure that (x) any Subject Registration
          Statement and any amendment thereto and any Prospectus forming part
          thereof and any supplement thereto complies in all material respects
          with the 1933 Act and the rules and regulations thereunder, (y)

                                      -8-
<PAGE>
 
          any Subject Registration Statement and any amendment thereto does not,
          when it becomes effective, contain an untrue statement of a material
          fact or omit to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading and (z) any
          Prospectus forming part of any Subject Registration Statement, and any
          supplement to such Prospectus (as amended or supplemented from time to
          time), does not include an untrue statement of a material fact or omit
          to state a material fact necessary in order to make the statements, in
          light of the circumstances under which they were made, not misleading.

     To the extent permitted by law, the Company further agrees, if necessary,
to supplement or amend the Shelf Registration Statement (if reasonably requested
by one firm of legal counsel selected by the Majority Holders) or the Purchaser
Shelf Registration Statement (if reasonably requested by Merrill Lynch), as the
case may be, with respect to information relating to the Holders or the Initial
Purchasers, respectively, and otherwise as required by Section 3(b) below, to
use its reasonable best efforts to cause any such amendment to become effective
and such Subject Registration Statement to become usable as soon as thereafter
practicable and to furnish to the Holders of Registrable Securities registered
thereby or the relevant Initial Purchasers, as the case may be, copies of any
such supplement or amendment promptly after its being used or filed with the
SEC. The Company may require, as a condition to including the Registrable
Securities of any Holder in any Subject Registration Statement, that such Holder
shall have furnished to the Company a written agreement to the effect that such
Holder agrees to comply with and be bound by the provisions of this Agreement.
For further clarity, the Company shall have no obligation to keep the Shelf
Registration Statement effective after consummation of the Exchange Offer, and
the Company's obligations to use its reasonable best efforts to file a Shelf
Registration Statement and to keep such Shelf Registration Statement effective
shall immediately terminate upon effectiveness of the Exchange Offer
Registration Statement (regardless of when such effectiveness shall occur).

          (c)  Expenses. The Company (i) shall pay all Registration Expenses in
               --------                                                        
connection with the registration pursuant to Section 2(a) or 2(b) and (ii) in
connection with the Exchange Offer Registration Statement and the Shelf
Registration Statement, shall reimburse the Holders of Registrable Securities
being tendered in the Exchange Offer and/or resold pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or
registered pursuant to the Shelf Registration Statement, as applicable (or to
the extent such fees and disbursements are paid to such counsel by the Initial
Purchasers, the Initial Purchasers), for the reasonable fees and disbursements
of not more than one counsel, to be chosen by the Holders of a majority in
principal amount of the Registrable Securities for whose benefit such
Registration Statement is being prepared. Each Holder (including each Initial
Purchaser) shall pay all expenses of its counsel other than as set forth in the
preceding sentence, underwriting discounts and commissions and transfer taxes,
if any, relating to the sale or disposition of such Holder's Registrable
Securities pursuant to any Subject Registration Statement or the exchange of its
Registrable Securities pursuant to any Exchange Offer Registration Statement.
Notwithstanding anything in this Agreement to the contrary, the Company shall
not be required to pay the fees and disbursements of legal counsel for any
Holders (including Initial Purchasers) except (A) as provided in clause (ii) of
the first sentence of this paragraph, (B) to the extent such fees and
disbursements constitute Registration Expenses which the Company is

                                      -9-
<PAGE>
 
required to pay pursuant to the other provisions of this Agreement and (C) to
the extent required by Section 5 hereof.

          (d)  Effective Registration Statement. (i) The Company will be deemed
               --------------------------------
not to have used its reasonable best efforts to cause the Exchange Offer
Registration Statement or any Subject Registration Statement, as the case may
be, to become, or to remain, effective during the requisite period if the
Company voluntarily takes any action that would result in any such Registration
Statement not being declared effective or in the Holders of Registrable
Securities covered thereby not being able to exchange or offer and sell such
Registrable Securities during that period unless such action is, in the
reasonable judgment of the Company, required by applicable law (including,
without limitation, any interpretation of the SEC).

               (ii) An Exchange Offer Registration Statement pursuant to Section
     2(a) hereof or a Subject Registration Statement pursuant to Section 2(b)
     hereof will not be deemed to have become effective unless it has been
     declared effective by the SEC; provided, however, that if, after it has
     been declared effective, the offering of Registrable Securities pursuant to
     such Subject Registration Statement is interfered with by any stop order,
     injunction or other order or requirement of the SEC or any other
     governmental agency or court, such Subject Registration Statement will be
     deemed not to have been effective during the period of such interference,
     until the offering of Registrable Securities pursuant to such Subject
     Registration Statement may legally resume.

          (e)  Increase in Interest Rate.  In the event that (i) the Exchange
               -------------------------                                     
Offer Registration Statement is not filed with the SEC on or prior to the 45th
calendar day after the Closing Date, (ii) the Exchange Offer Registration
Statement is not declared effective by the SEC on or prior to the 105th calendar
day after the Closing Date or (iii) the Exchange Offer is not consummated or a
Shelf Registration Statement is not declared effective by the SEC on or prior to
the 180th calendar day after the Closing Date, the interest rate borne by the
Debt Securities shall be increased by 0.50% per annum, as liquidated damages,
following such 45th day in the case of clause (i) above, such 105th day in the
case of clause (ii) above, or such 180th day in the case of clause (iii) above;
provided, however, that the aggregate amount of any such increase in such
interest rate will in no event exceed 0.50% per annum; and provided, further
that if the Exchange Offer Registration Statement is not declared effective by
the SEC on or prior to the 105th day following the Closing Date, then Debt
Securities owned by Persons who do not comply in all material respects with
their obligations under the penultimate paragraph of Section 3 will not be
entitled to any such increase in the interest rate for any day after the 180th
day following the Closing Date. Upon (A) the filing of the Exchange Offer
Registration Statement after the 45th day described in clause (i) above, (B) the
effectiveness of the Exchange Offer Registration Statement after the 105th day
described in clause (ii) above or (C) the consummation of the Exchange Offer or
the effectiveness of a Shelf Registration Statement, as the case may be, after
the 180th day described in clause (iii) above, the interest rate borne by the
Debt Securities from the date of such filing, effectiveness or consummation
(effective immediately preceding such consummation), as the case may be, will be
reduced to the original interest rate; provided, however, that the interest rate
borne by the Debt Securities will be  reduced to the original

                                      -10-
<PAGE>
 
interest rate only if there is not then continuing a default with respect to any
of the events set forth in the immediately preceding sentence causing the
interest rate borne by the Debt Securities to increase.

          (f)  Specific Enforcement. Without limiting the remedies available to
               --------------------                                            
the Initial Purchasers and the Holders, the Company acknowledges that any
failure by the Company to comply with its obligations under Section 2(a) and
Section 2(b) 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, to the
extent permitted by law, obtain such relief as may be required to specifically
enforce the Company's obligations under Section 2(a) and Section 2(b) hereof.

 Section  3.   Registration Procedures.

     In connection with the obligations of the Company with respect to the
Registration Statements pursuant to Sections 2(a) and 2(b) hereof, but only so
long as the Company shall have an obligation under this Agreement to keep a
Registration Statement effective, the Company shall:

          (a)  use its reasonable best efforts to prepare and file with the SEC
a Registration Statement, within the relevant time period specified in Section
2, on the appropriate form under the 1933 Act, which form (i) shall be selected
by the Company, (ii) shall, in the case of a Shelf Registration, be available
for the sale of the Registrable Securities by the selling Holders thereof and
(iii) shall comply as to form in all material respects with the requirements of
the applicable form and include or incorporate by reference all financial
statements required by the SEC to be filed therewith, and use its reasonable
best efforts to cause such Registration Statement to become effective and use
its reasonable best efforts to cause such Registration Statement to remain
effective in accordance with Section 2 hereof;

          (b)  to the extent permitted by law, use its reasonable best efforts
to (i) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary under applicable
law to keep such Registration Statement effective for the applicable period,
(ii) cause each Prospectus to be supplemented by any required prospectus
supplement, and as so supplemented to be filed (if required) pursuant to Rule
424 under the 1933 Act, and (iii) comply with the provisions of the 1933 Act
with respect to the disposition of all securities covered by each Registration
Statement during the applicable period in accordance with the intended method or
methods of distribution by the selling Holders thereof;

          (c)  in the case of a Shelf Registration, (i) notify each Holder of
Registrable Securities, at least ten business days prior to filing, that the
Shelf Registration Statement with respect to the Registrable Securities is being
filed and advising such Holders that the distribution of Registrable Securities
will be made in accordance with the method elected by the Majority Holders; and
(ii) furnish to each Holder of Registrable Securities registered under the Shelf
Registration Statement, to a single firm of legal counsel for the Holders
(including the Initial Purchasers) and to the managing underwriters of an
underwritten offering of Registrable Securities, if any, and their

                                      -11-
<PAGE>
 
counsel, without charge, as many copies of each Prospectus, including each
preliminary prospectus, and any amendment or supplement thereto and documents
incorporated by reference therein as such Holder, counsel or underwriters may
reasonably request and, if the Holder so requests, all exhibits thereto
(including those incorporated by reference) in order to facilitate the public
sale or other disposition of the Registrable Securities; and (iii) subject to
Section 3(k) hereof and the last paragraph of this Section 3, hereby consent to
the use of the Prospectus or any amendment or supplement thereto by each of the
selling Holders of Registrable Securities in connection with the offering and
sale of the Registrable Securities covered by the Prospectus or any amendment or
supplement thereto but only during the period of time that the Company is
required to keep the Shelf Registration Statement effective pursuant to this
Agreement;

          (d)  use its reasonable best efforts to register or qualify the
Registrable Securities under all applicable state securities or "blue sky" laws
of such jurisdictions in the United States as the Majority Holders of
Registrable Securities covered by a Registration Statement and the managing
underwriter of an underwritten offering of Registrable Securities shall
reasonably request prior to the time the applicable Registration Statement is
declared effective by the SEC, to cooperate with the Holders in connection with
any filings required to be made with the NASD, and do any and all other acts and
things which may be reasonably necessary or advisable to enable such Holder to
consummate the disposition of such Registrable Securities in the jurisdiction of
such Holder pursuant to such Registration Statement; provided, however, that the
Company shall not be required to (i) qualify as a foreign corporation or as a
dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d) or (ii) take any action that would
subject it to general service of process or taxation in any such jurisdiction if
it is not then so subject;

          (e)  in the case of a Subject Registration Statement, promptly notify
a single firm of legal counsel for the Holders of Registrable Securities
registered thereby (including any Initial Purchasers) and Merrill Lynch and, if
requested by such counsel or Merrill Lynch, promptly confirm such advice in
writing (by notice to such counsel or to Merrill Lynch) (i) when such
Registration Statement has become effective and when any post-effective
amendments thereto become effective, (ii) of any request by the SEC or any state
securities authority for post-effective amendments and supplements to such
Registration Statement and the related Prospectus or for additional information
after such Registration Statement has become effective, (iii) of the issuance by
the SEC or any state securities authority of any stop order suspending the
effectiveness of such Registration Statement or the initiation of any
proceedings for that purpose, (iv) if, between the effective date of such
Registration Statement and the closing of any sale of Registrable Securities
covered thereby pursuant to an underwriting agreement to which the Company is a
party, the representations and warranties of the Company contained in such
underwriting agreement cease to be true and correct in all material respects,
(v) of the receipt by the Company of any notification with respect to the
suspension of the qualification of the Registrable Securities covered by such
Registration Statement for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose and (vi) upon the Company
becoming aware thereof, of the happening of any event or the discovery of any
facts during the period such Registration Statement is effective which (A) makes
any statement made in such Registration Statement or the related Prospectus
untrue in any material respect or (B) causes such Registration Statement or the
related Prospectus to omit to state a material fact necessary in order to

                                      -12-
<PAGE>
 
make the statements therein, in the light of the circumstances under which they
were made, not misleading;

          (f)  (i)  in the case of the Exchange Offer, (A) include in the
Exchange Offer Registration Statement a "Plan of Distribution" section covering
the use of the Prospectus included in the Exchange Offer Registration Statement
by Participating Broker-Dealers (as defined below) who have exchanged their
Registrable Securities for Exchange Securities for the resale of such Exchange
Securities, (B) furnish to each Participating Broker-Dealer who notifies the
Company in writing that it desires to participate in the Exchange Offer, without
charge, as many copies of each Prospectus included in the Exchange Offer
Registration Statement, including any preliminary prospectus, and any amendment
or supplement thereto, as such broker-dealer may reasonably request, (C) include
in the Exchange Offer Registration Statement a statement that any broker-dealer
who holds Registrable Securities acquired for its own account as a result of
market-making activities or other trading activities (a "Participating Broker-
Dealer"), and who receives Exchange Securities for Registrable Securities
pursuant to the Exchange Offer, may be a statutory underwriter and must deliver
a prospectus meeting the requirements of the 1933 Act in connection with any
resale of such Exchange Securities, (D) subject to Section 3(k) hereof and the
last paragraph of this Section 3, hereby consent to the use of the Prospectus
forming part of the Exchange Offer Registration Statement or any amendment or
supplement thereto by any Participating Broker-Dealer in connection with the
sale or transfer of the Exchange Securities covered by the Prospectus or any
amendment or supplement thereto for a period ending 180 days following
consummation of the Exchange Offer or, if earlier, when all Exchange Securities
received by such Participating Broker-Dealer in exchange for Registrable
Securities acquired for their own account as a result of market-making or other
trading activities have been disposed of by such Participating Broker-Dealer,
and (E) include in the letter of transmittal or similar documentation to be
executed by an exchange offeree in order to participate in the Exchange Offer a
provision substantially in the following form (or such similar provision as is
reasonably acceptable to counsel for the Initial Purchasers and as, in the
reasonable opinion of the Company, may at the time be required by applicable law
or SEC interpretation):

          "the undersigned is not a broker-dealer, the undersigned
          represents that it is not engaged in, and does not intend to
          engage in, a distribution of Exchange Securities. If the
          undersigned is a broker-dealer that will receive Exchange
          Securities for its own account in exchange for Registrable
          Securities, it represents that the Registrable Securities to
          be exchanged for Exchange Securities were acquired by it as
          a result of market-making activities or other trading
          activities and acknowledges that it will deliver a
          prospectus meeting the requirements of the 1933 Act in
          connection with any resale of such Exchange Securities
          pursuant to the Exchange Offer; however, by so acknowledging
          and by delivering a prospectus, the undersigned will not be
          deemed to admit that it is an "underwriter" within the
          meaning of the 1933 Act"; and

                                      -13-
<PAGE>
 
               (ii)   to the extent any Participating Broker-Dealer participates
     in the Exchange Offer, the Company shall use its reasonable best efforts to
     cause to be delivered at the request of an entity representing the
     Participating Broker-Dealers (which entity shall be Merrill Lynch or
     another Initial Purchaser) (A) a "cold comfort" letter addressed to the
     Participating Broker-Dealers from the Company's independent certified
     public accountants with respect to the Prospectus in the Exchange Offer
     Registration Statement in the form existing on the last date for which
     exchanges are accepted pursuant to the Exchange Offer and (B) an opinion of
     counsel to the Company addressed to the Participating Broker-Dealers in
     customary form relating to the Exchange Securities; and
 
               (iii)  to the extent any Participating Broker-Dealer participates
     in the Exchange Offer and notifies the Company or causes the Company to be
     notified in writing that it is a Participating Broker-Dealer, the Company
     shall use its reasonable best efforts to maintain the effectiveness of the
     Exchange Offer Registration Statement for a period of 180 days following
     the last date on which exchanges are accepted pursuant to the Exchange
     Offer, or, if earlier, when all Exchange Securities received by
     Participating Broker-Dealers in exchange for Registrable Securities
     acquired for their own account as a result of market-making or other
     trading activities have been disposed of by such Participating Broker-
     Dealers; and

               (iv)   not be required, however, to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement as would
     otherwise be contemplated by Section 3(b) hereof, or take any other action
     as a result of this Section 3(f), at any time after 180 days after the last
     date for which exchanges are accepted pursuant to the Exchange Offer (or
     such earlier date referred to in Paragraph (C) above), and Participating
     Broker-Dealers shall not be authorized by the Company to, and shall not,
     deliver such Prospectus after such period in connection with resales
     contemplated by this Section 3 or otherwise;

     it being understood that, notwithstanding anything in this Agreement to the
contrary, the Company shall not be required to comply with any provision of this
Section 3(f) or any other provision of this Agreement relating to the
distribution of Exchange Securities by Participating Broker-Dealers, to the
extent that the Company reasonably concludes (with the consent of Merrill Lynch,
not to be unreasonably withheld) that compliance with such provision is no
longer required by applicable law or interpretation of the staff of the SEC;

          (g)  in the case of an Exchange Offer, furnish to one firm of legal
counsel for the Initial Purchasers and (ii) in the case of a Shelf Registration,
furnish to one firm of legal counsel for the Holders of Registrable Securities
covered thereby copies of any request received by or on behalf of the Company,
from the SEC or any state securities authority for amendments or supplements to
the relevant Registration Statement and Prospectus or for additional
information;

          (h)  make every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement as soon as
practicable and provide prompt notice to one firm of legal counsel for the
Holders of the withdrawal of any such order;

                                      -14-
<PAGE>
 
          (i)  in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities registered thereby, without charge, at least one
conformed copy of each Registration Statement and any post-effective amendment
thereto (without documents incorporated therein by reference or exhibits
thereto, unless requested);

          (j)  in the case of a Shelf Registration, cooperate with the selling
Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legend (except any customary legend borne by securities
held through The Depository Trust Company or any similar depository); and cause
such Registrable Securities to be in such denominations (consistent with the
provisions of the Indenture) and registered in such names as the selling Holders
or the underwriters, if any, may reasonably request at least two business days
prior to the closing of any sale of Registrable Securities;

          (k)  in the case of a Shelf Registration, upon the Company becoming
aware of the occurrence of any event or the discovery of any facts, each as
contemplated by Section 3(e)(vi) hereof, use its reasonable best efforts to
prepare a supplement or post-effective amendment to the relevant Registration
Statement or the related Prospectus or any document incorporated therein by
reference or file any other required document so that, as thereafter delivered
to the purchasers of the Registrable Securities, such Prospectus will not
contain at the time of such delivery any untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading. The Company
agrees to notify each Holder of Registrable Securities registered under the
relevant Subject Registration Statement to suspend use of the Prospectus as
promptly as practicable after the Company becomes aware of the occurrence of
such an event, and each Holder of Registrable Securities registered under the
relevant Subject Registration Statement hereby agrees to suspend use of the
Prospectus after receipt of such notice until the Company has amended or
supplemented the Prospectus to correct such misstatement or omission or has
advised such Holders that use of such Prospectus may be resumed. At such time as
such public disclosure is otherwise made or the Company determines that such
disclosure is not necessary, in each case to correct any misstatement of a
material fact or to include any omitted material fact, or the Company otherwise
determines that use of such Prospectus may be resumed, the Company agrees
promptly to notify each Holder of Registrable Securities registered under the
relevant Subject Registration Statement of such determination and (if
applicable) to furnish each such Holder such numbers of copies of the
Prospectus, as amended or supplemented, as such Holder may reasonably request;

          (l)  obtain a CUSIP number for all Exchange Securities, or Registrable
Securities, as the case may be, not later than the effective date of a
Registration Statement, and provide the Trustee with printed certificates for
the Exchange Securities or the Registrable Securities, as the case may be, in a
form eligible for deposit with The Depository Trust Company; provided, however,
that the Company shall not be required to provide printed certificates for any
Exchange Securities or Registrable Securities to be so-called "book-entry only"
securities;

          (m)  unless the Indenture, as it relates to the Exchange Securities or
the Registrable Securities, as the case may be, has already been so qualified,
use its reasonable best efforts to (i) cause

                                      -15-
<PAGE>
 
the Indenture to be qualified under the Trust Indenture Act of 1939, as amended
(the "TIA"), in connection with the registration of the Exchange Securities or
Registrable Securities, as the case may be, (ii) cooperate with the Trustee and
the Holders to effect such changes to the Indenture as may be required for the
Indenture to be so qualified in accordance with the terms of the TIA and (iii)
execute, and use its reasonable best efforts to cause the Trustee to execute,
all documents as may be required to effect such changes, and all other forms and
documents required to be filed with the SEC to enable the Indenture to be so
qualified in a timely manner;

          (n)  in the case of a Shelf Registration, take all customary and
appropriate actions (including those reasonably requested by the Majority
Holders) in order to expedite or facilitate the disposition of the Registrable
Securities registered thereby. If requested as set forth below, the Company
agrees that it will in good faith negotiate the terms of an Underwriting
Agreement, which shall be in form and scope as is customary for similar
offerings of debt securities with similar credit ratings (including, without
limitation, representations and warranties to the underwriters) and shall
otherwise be reasonably satisfactory to the Company and the managing
underwriters; and:

               (i)    if requested by the managing underwriters, obtain opinions
     of counsel to the Company (which counsel shall be reasonably satisfactory
     to the managing underwriters) addressed to such underwriters, covering the
     matters customarily covered in opinions requested in underwritten sales of
     securities in substantially the forms specified in the Underwriting
     Agreement;

               (ii)   if requested by the managing underwriters, obtain a "cold
     comfort" letter and an update thereto not later than two weeks after the
     date of the original letter (or if not available under applicable
     accounting pronouncements or standards, a single "procedures" letter and a
     single update thereto) from the Company's independent certified public
     accountants addressed to the underwriters named in the Underwriting
     Agreement and use its reasonable best efforts to have such letter addressed
     to the selling Holders of Registrable Securities (provided, however, that
     such letter need not be addressed to any Holders to whom, in the reasonable
     opinion of the Company's independent certified public accountants,
     addressing such letter is not permissible under applicable accounting
     standards), such letters to be in customary form and covering matters of
     the type customarily covered in "cold comfort" (or "procedures") letters to
     underwriters in connection with similar underwritten offerings; and

               (iii)  deliver such documents and certificates as may be
     reasonably requested and as are customarily delivered in similar
     underwritten offerings.

     Notwithstanding anything herein to the contrary, the Company shall have no
obligation to enter into any underwriting agreement or permit an underwritten
offering of Registrable Securities unless a request therefor shall have been
received from at least 33 1/3% of the Holders of all Registrable Securities then
outstanding. In the case of such a request for an underwritten offering, the
Company shall provide written notice to the Holders of all Registrable
Securities of such underwritten offering at least 30 days prior to the filing of
a Shelf Registration Statement or a prospectus supplement

                                      -16-
<PAGE>
 
providing for such underwritten offering. Such notice shall (A) offer each such
Holder the right to participate in such underwritten offering (but may indicate
that whether or not all Registrable Securities are included will be at the
discretion of the underwriters), (B) specify a date, which shall be no earlier
than ten business days following the date of such notice, by which such Holder
must inform the Company of its intent to participate in such underwritten
offering and (C) include the instructions such Holder must follow in order to
participate in such underwritten offering;

          (o)  in the case of a Shelf Registration, and to the extent customary
in connection with a "due diligence" investigation for an offering of debt
securities with a similar credit rating to that of the Registrable Securities,
make reasonably available for inspection by representatives appointed by the
Majority Holders and any underwriters participating in any disposition pursuant
to a Shelf Registration Statement and one firm of legal counsel retained for all
Holders participating in such Shelf Registration, and one firm of legal counsel
to the underwriters, if any, all financial and other records, pertinent
corporate documents and properties of the Company reasonably requested by any
such persons, and cause the respective officers, employees and any other agents
of the Company to supply all information reasonably requested by any such
representative, underwriters or counsel in connection with the Shelf
Registration Statement; provided, however, that, if any such records, documents
or other information relates to pending or proposed acquisitions or
dispositions, or otherwise relates to matters reasonably considered by the
Company to constitute sensitive or proprietary information, the Company need not
provide such records, documents or information unless the foregoing parties
enter into a confidentiality agreement in customary form and reasonably
acceptable to such parties and the Company;

          (p)  (i)  a reasonable time prior to the filing of any Exchange Offer
Registration Statement, any Prospectus forming a part thereof, any amendment to
an Exchange Offer Registration Statement or amendment or supplement to such
Prospectus, provide copies of such document to the Initial Purchasers, and make
such changes in any such document prior to the filing thereof as Merrill Lynch
or one firm of legal counsel to the Initial Purchasers may reasonably request;
(ii) in the case of a Shelf Registration, a reasonable time prior to filing any
Shelf Registration Statement, any Prospectus forming a part thereof, any
amendment to such Shelf Registration Statement or amendment or supplement to
such Prospectus, provide copies of such document to Merrill Lynch, one firm of
legal counsel appointed by the Majority Holders to represent the Holders
participating in such Shelf Registration, the managing underwriters of an
underwritten offering of Registrable Securities, if any, and their counsel, and
make such changes in any such document prior to the filing thereof as Merrill
Lynch, such one firm of legal counsel for the Holders, such managing
underwriters or their counsel may reasonably request; and (iii) cause the
representatives of the Company to be available for discussion of such document
as shall be reasonably requested by Merrill Lynch, one firm of legal counsel to
the Holders, the managing underwriters and their counsel; and shall not at any
time make any filing of any such document of which Merrill Lynch, one firm of
legal counsel to the Holders, the managing underwriters and their counsel shall
not have previously been advised and furnished a copy or to which Merrill Lynch,
one firm of legal counsel to the Holders, the managing underwriters and their
counsel shall reasonably object; provided, however, that the provisions of this
paragraph (p) shall not apply to any document filed by the Company pursuant to
the 1934 Act which is incorporated or deemed to be incorporated by reference in
any Registration Statement or Prospectus;

                                      -17-
<PAGE>
 
          (q)  in the case of a Shelf Registration and if requested by the
managing underwriters, if any, or the Majority Holders, (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information or revisions to information therein relating to such
Underwriters or selling Holders as the managing underwriters, if any, or such
Holders or their counsel reasonably request to be included or made therein, (ii)
make all required filings of such prospectus supplement or such post-effective
amendment as soon as practicable after the Company has received notification of
the matters to be incorporated in such prospectus supplement or post-effective
amendment and (iii) if required, supplement or make amendments to such Shelf
Registration Statement;

          (r)  upon delivery of the Registrable Securities by Holders to the
Company (or to such other Person as directed by the Company) in exchange for the
Exchange Securities, the Company shall mark, or cause to be marked, on such
Registrable Securities that such Registrable Securities are being canceled in
exchange for the Exchange Securities; in no event shall such Registrable
Securities be marked as paid or otherwise satisfied;

          (s)  use its reasonable best efforts to cause the Exchange Securities,
if applicable, and, in the event of a Shelf Registration, the Debt Securities to
be rated with not more than two rating agencies selected by the Company, if so
requested by the Majority Holders or by the managing underwriters of an
underwritten offering of Registrable Securities, if any, unless the Exchange
Securities or the Registrable Securities, as the case may be, are already so
rated or unless the Company has obtained such ratings for its long-term debt
securities generally;

          (t)  otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the SEC and make generally available to its
security holders, as soon as reasonably practicable, an earnings statement
covering at least 12 months which shall satisfy the provisions of Section 11(a)
of the 1933 Act and Rule 158 thereunder; and

          (u)  reasonably cooperate and assist in any filings required to be
made with the NASD and in the performance of any due diligence investigation by
any managing underwriters and their counsel.

     In the case of a Subject Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) (i) require
each Holder of Registrable Securities to furnish to the Company such information
regarding such Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing and such other information as, in the reasonable opinion of the
Company, is required for inclusion in the Subject Registration Statement, and
(ii) further require each Holder of Registrable Securities, through one firm of
legal counsel on behalf of all such Holders, to furnish to the Company any
comments on the Subject Registration Statement and the Prospectus included
therein or any amendment or supplement to any of the foregoing not later than
such times as the Company reasonably may request.  Each Holder of Securities
included in a Subject Registration Statement agrees promptly to notify the
Company of any inaccuracy or change in information previously furnished to the
Company or the occurrence of any event, in either case, as a result of which the

                                      -18-
<PAGE>
 
relevant Registration Statement or the related Prospectus contains or would
contain an untrue statement of a material fact or omits or would omit to state
any material fact regarding such Holder, its intended method of distribution of
Registrable Securities or otherwise that is required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing. As soon as practicable, the Company will, subject
to the reasonable approval of its counsel, incorporate in a supplement or post-
effective amendment to the relevant Registration Statement or related Prospectus
such information furnished in writing to the Company and requested to be
included therein, and furnish to such Holder copies of the Prospectus, as
amended or supplemented, as reasonably requested.

     In the case of a Subject Registration Statement, each Holder agrees and, in
the case of the Exchange Offer Registration Statement, each Participating
Broker-Dealer agrees that, upon receipt of any notice from the Company of the
happening of any event or the discovery of any facts, each of the kind described
in Section 3(e)(ii)-(vi) or Section 3(k) hereof (it being understood and agreed
that, for purposes of this paragraph, all references in Sections 3(e)(ii)-(vi)
and Section 3(k) to a "Subject Registration Statement", a "Shelf Registration
Statement" or a "Registration Statement" shall be deemed to mean and include the
Shelf Registration Statement, the Purchaser Shelf Registration Statement or the
Exchange Offer Registration Statement or all or any combination thereof (as the
context requires), mutatis mutandis), such Holder or Participating Broker-
Dealer, as the case may be, will forthwith discontinue disposition of
Registrable Securities pursuant to such Registration Statement and discontinue
use of the Prospectus included therein until such Holder's or Participating
Broker-Dealer's receipt, as the case may be, of (A) copies of the supplemented
or amended Prospectus contemplated by Section 3(k) hereof or (B) notice from the
Company that the sale of the Registrable Securities may be resumed, and, if so
directed by the Company, such Holder or Participating Broker-Dealer, as the case
may be, will deliver to the Company (at its expense) all copies in its
possession, other than permanent file copies then in its possession, of the
Prospectus covering such Registrable Securities current at the time of receipt
of such notice. If the Company shall give any such notice to suspend the
disposition of Registrable Securities pursuant to a Registration Statement as a
result of the happening of any event or the discovery of any facts, each of the
kind described in Section 3(e) (ii)-(vi) or 3(k) hereof, the Company shall be
deemed to have used its reasonable best efforts to keep such Registration
Statement effective during such period of suspension, provided that the Company
shall use its reasonable best efforts to file and have declared effective (if an
amendment) as soon as practicable an amendment or supplement to such
Registration Statement or the related Prospectus and shall extend the period
during which such Registration Statement shall be maintained effective pursuant
to this Agreement by the number of days during the period from and including the
date of the giving of such notice to and including the date when the Holders
shall have received copies of the supplemented or amended Prospectus necessary
to resume such dispositions or the date on which the Company has given notice
that the sale of Registrable Securities may be resumed, as the case may be.
Each Holder of Registrable Securities hereby agrees that it will at all times
use the then most current Prospectus, as then amended or supplemented, which has
been provided to it by the Company in connection with the resale or transfer of
any Registrable Securities pursuant to a Registration Statement or Prospectus.

                                      -19-

Section 4.   Underwritten Registrations.

     If any of the Registrable Securities covered by the Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage the offering will be
selected by the Company and shall be reasonably acceptable to the Majority
Holders of such Registrable Securities included in such offering.

     No Holder of Registrable Securities may participate in any underwritten
offering hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Securities on the basis provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

Section 5.   Indemnification and Contribution.

          (a)  The Company shall  indemnify and hold harmless each Initial
Purchaser, each Holder and each Person, if any, who controls any such Person
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
as follows:

               (i)    against any and all losses, liabilities, claims, damages
     and expenses whatsoever, as incurred, arising out of any untrue statement
     or alleged untrue statement of a material fact contained in any
     Registration Statement (or any amendment thereto) pursuant to which
     Exchange Securities or Registrable Securities were registered under the
     1933 Act, including all documents incorporated therein by reference, or the
     omission or alleged omission therefrom of a material fact required to be
     stated therein or necessary to make the statements therein not misleading
     or arising out of any untrue statement or alleged untrue statement of a
     material fact contained in any Prospectus (or any amendment or supplement
     thereto) or the omission or alleged omission therefrom of a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

               (ii)   against any and all losses, liabilities, claims, damages
     and expenses whatsoever, as incurred, to the extent of the aggregate amount
     paid in settlement of any litigation, or any investigation or proceeding by
     any governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     5(e) below) any such settlement is effected with the written consent of the
     Company; and

               (iii)  against any and all expenses whatsoever, as incurred
     (including (subject to Section 5(c) below) the reasonable fees and
     disbursements of counsel chosen by Merrill Lynch or, in the event that
     Merrill Lynch is not an indemnified party, by a majority of the indemnified
     parties), reasonably incurred in investigating, preparing or defending
     against any litigation, or any investigation or proceeding by any
     governmental agency or body,

                                      -20-
<PAGE>
 
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under subparagraph (i) or (ii)
     of this Section 5(a);

     provided, however, that this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of any Initial Purchaser, any Holder or any underwriter expressly for
use in the Registration Statement (or any amendment thereto) or the Prospectus
(or any amendment or supplement thereto); and provided, further, that this
indemnity agreement with respect to any Prospectus shall not inure to the
benefit of any Initial Purchaser or Holder from whom the person asserting any
such losses, claims, damages or liabilities purchased Registrable Securities or
Exchange Securities (or any person who controls such Initial Purchaser or Holder
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act)
if a copy of the Prospectus (as then amended or supplemented and furnished by
the Company to such Initial Purchaser or Holder, as the case may be) was not
sent or given by or on behalf of such Initial Purchaser or Holder, as the case
may be, to such person at or prior to the sale of such Registrable Securities or
Exchange Securities and if the Prospectus (as so amended or supplemented) would
have corrected any untrue statement or omission, or alleged untrue statement or
omission, giving rise to such loss, liability, claim, damage or expense
(provided the Company has delivered the Prospectus (as then amended or
supplemented) to the several Initial Purchasers or Holders in requisite quantity
on a timely basis to permit such delivery or sending).

          (b)  In the case of a Shelf Registration, each Holder agrees,
severally and not jointly, to indemnify and hold harmless the Company, each
Initial Purchaser, each underwriter who participates in an offering of
Registrable Securities and the other Holders and each of their respective
directors and officers (including each officer of the Company who signed the
Registration Statement in question) and each Person, if any, who controls the
Company, any Initial Purchaser, any underwriter or any other Holder within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any
and all losses, liabilities, claims, damages and expenses described in the
indemnity contained in Section 5(a) hereof, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Registration Statement (or any amendment thereto) or the Prospectus
(or any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by or on behalf of such Holder
expressly for use in the Registration Statement (or any amendment thereto) or
the Prospectus (or any amendment or supplement thereto); provided, however, that
no such Holder shall be liable for any claims hereunder in excess of the amount
of net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Registration Statement.

          (c)  Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have other than on account of this

                                      -21-
<PAGE>
 
indemnity agreement or the contribution agreement set forth in Section 5(d)
below. In the case of parties indemnified pursuant to Section 5(a) above,
counsel to the indemnified parties shall be selected by Merrill Lynch (or, in
the event that Merrill Lynch is not an indemnified party, by a majority in
interest of the indemnified parties), and, in the case of parties indemnified
pursuant to Section 5(b) above, counsel to the indemnified parties shall be
selected by the Company.  Notwithstanding the foregoing, in case any action or
proceeding shall be instituted and the indemnified party shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein, and, after written notice from the indemnifying
party to such indemnified party, to assume the defense thereof with counsel of
its choice reasonably acceptable to the indemnified parties in such action.
Notwithstanding the election of the indemnifying party to assume defense of such
action or proceeding, the indemnified party shall have the right, at its own
expense, to employ one additional firm as separate counsel and to participate in
the defense of the action or proceeding; provided that the indemnifying party
shall pay the reasonable fees and expenses of such separate counsel reasonably
satisfactory to the indemnifying party if (i) the indemnifying party shall have
failed to employ counsel to represent the indemnified party in a reasonably
timely manner or (ii) the defendants in any such action or proceeding include
both the indemnified party and the indemnifying party and counsel to the
indemnified party shall have concluded and notified the indemnifying party that
in its reasonable judgment representation of both parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them.  In no event shall the indemnifying parties be liable for the fees and
expenses of more than one counsel (in addition to any local counsel) (which
counsels shall be selected by Merrill Lynch or, in the event that Merrill Lynch
is not an indemnified party, by a majority in interest of the indemnified
parties) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 5 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim 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 any indemnified party.

          (d)  In order to provide for just and equitable contribution in
circumstances in which any of the indemnity provisions set forth in this Section
5 are for any reason held to be unenforceable by the indemnified parties
although applicable in accordance with its terms, the Company, the Initial
Purchasers and the Holders shall contribute to the aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement incurred by the Company, the Initial Purchasers and the
Holders, as incurred; provided, however, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any Person that was not guilty of such fraudulent
misrepresentation. As between the Company, the Initial Purchasers and the
Holders, such parties shall contribute to such aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such

                                      -22-
<PAGE>
 
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company on the one hand, the Initial Purchasers on another
hand, and the Holders on another hand, with respect to the statements or
omissions which resulted in such loss, liability, claim, damage or expense, or
action in respect thereof, as well as any other relevant equitable
considerations. The relative fault of the Company on the one hand, the Initial
Purchasers on another hand, and the Holders on another 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 by the Initial
Purchasers or by the Holders and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such untrue or alleged
untrue statement or omission. The Company, the Initial Purchasers and the
Holders agree that it would not be just and equitable if contribution pursuant
to this Section 5(d) were to be determined by pro rata allocation or by any
other method of allocation that does not take into account the relevant
equitable considerations. For purposes of this Section 5(d), each Person, if
any, who controls an Initial Purchaser or a Holder within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as such Initial Purchaser or such Holder, and each director of the
Company, each officer of the Company who signed the Registration Statement in
question, and each Person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company.

          (e)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 5(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

Section 6.   Miscellaneous.

          (a)  Rule 144 and Rule 144A. Until the earliest of (i) the completion
               ----------------------                                          
of the Exchange Offer, (ii) two years following the Closing Date (or such
shorter period as may be specified in Rule 144(k) as then amended) and (iii) the
date when all Registrable Securities have been sold pursuant to the Subject
Registration Statement or are no longer Registrable Securities, the Company
covenants that it will file the reports required to be filed by it under Section
13(a) or 15(d) of the 1934 Act and the rules and regulations adopted by the SEC
thereunder for so long as the Company is subject to the reporting requirements
of Section 13 or 15 of the 1934 Act, and if the Company ceases to be so required
to file such reports, it will upon the request of any Holder of Registrable
Securities (i) make publicly available such information as is necessary to
permit sales pursuant to Rule 144 under the 1933 Act, (ii) deliver such
information to a prospective purchaser as is necessary to permit sales pursuant
to Rule 144A under the 1933 Act and (iii) take such further action that is
reasonable in the circumstances, in each case, to the extent required from time
to time to enable such Holder to sell its Registrable Securities without
registration under the 1933 Act within the limitation of the exemptions

                                      -23-
<PAGE>
 
provided by (A) Rule 144 under the 1933 Act, as such Rule may be amended from
time to time, (B) Rule 144A under the 1933 Act, as such Rule may be amended from
time to time or (C) any similar rules or regulations hereafter adopted by the
SEC (provided that the obligations of the Company under any such similar rules
or regulations shall not be more burdensome in any substantial respect than
those referred to in clauses (A) or (B)). Upon the request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such requirements.

          (b)  No Inconsistent Agreements.  The Company has not entered into nor
               --------------------------                                       
will the Company on or after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
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
other issued and outstanding securities under any such agreements.

          (c)  Amendments and Waivers.  The provisions of this Agreement,
               ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure; provided, however, that to the extent any provision of this
Agreement relates to the Purchaser Shelf Registration Statement or otherwise to
the Initial Purchasers, such provision may be amended, modified or supplemented,
and waivers or consents to departures from such provisions thereof may be given,
by Merrill Lynch; and provided, further, that no amendment, modification,
supplement or waiver or consent to any departure from the provisions of Section
5 hereof shall be effective as against any Holder of Registrable Securities
unless consented to in writing by such Holder. Notwithstanding anything in this
Agreement to the contrary, this Agreement may be amended, modified or
supplemented, and waivers and consents to departures from the provisions hereof
may be given, by written agreement signed by the Company and Merrill Lynch to
the extent that any such amendment, modification, supplement, waiver or consent
is, in their reasonable judgment, necessary or appropriate to comply with
applicable law (including any interpretation of the staff of the SEC) or any
change therein.

          (d)  Notices. All notices and other communications provided for or
               -------

this Section 6(d), which address initially is, with respect to the Initial
Purchasers, the address care of Merrill Lynch set forth in the Purchase
Agreement, and (ii) if to the Company initially at or in care of the Company's

assignment, subsequent Holders; provided, however, that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms hereof or of the Purchase Agreement, the
Indenture or the Offering Memorandum dated March 26, 1997; and provided,
further, that Holders of Registrable Securities may not assign their rights
under this Agreement except in connection with the permitted transfer of
Registrable Securities and then only insofar as relates to such Registrable
Securities. If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable 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 and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

          (f)  Third-Party Beneficiary. The Holders from time to time shall each

Company, on the one hand, and the Initial Purchasers, on the other hand, and
Merrill Lynch shall have the right to enforce such agreements directly to the
extent it deems such enforcement necessary or advisable to protect its rights or
the rights of Holders hereunder.

          (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.

          (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.

(a)  Because their impact is less than 3% dilutive, common stock equivalents are
     not included in the calculation of primary earnings per share as disclosed
     on the statement of operations for the three months ended March 31, 1997
     and 1996.

(b)  Fully diluted earnings per share is less than 3% lower than primary
     earnings per share for the three months ended March 31, 1997.
