                                    ARTICLE I

                                   DEFINITIONS

                  SECTION 1.01. Definitions. The following terms, as used
herein, have the following meanings:

                  "Adjusted Cash" means, as of any date, the lesser of (i) the
amount by which cash and short-term investments of the Issuer and its
Subsidiaries exceed $5,000,000 and (ii) the amount, if any, by which (a) current
assets of the Issuer and its Subsidiaries exceed (b) current liabilities of such
Persons (excluding the aggregate outstanding principal amount of Debt included
in such current liabilities), in each case determined on a consolidated basis as
of such date. If such current liabilities exceed such current assets, Adjusted
Cash shall be zero.

                  "Affiliate" means each Person who controls, is controlled by
or is under common control with the Issuer. For purposes of this definition, the
term "control" means possession, directly or indirectly, of the power to direct
or cause the direction of the management or policies of a Person, whether
through the ownership of voting securities, by contract or otherwise.

                  "Asset Disposition" means any sale, lease, transfer or other
disposition of shares of capital stock of a Subsidiary, property or other assets
by the Issuer or a Subsidiary, other than any such sales, leases, transfers or
other dispositions of assets made in the ordinary course of business.

                  "Attributable Debt" means, as to any particular lease and at
any date, the total net amount of rent required to be paid by such Person under
such lease during the remaining primary term thereof (or any renewal terms for
which the lease may be extended at the option of the lessor), discounted from
the respective due dates thereof to such date at a rate of 7.19% per annum. The
net amount of rent required to be paid under any such lease for any such period
shall be the aggregate amount of rent payable by the lessee with respect to such
period after excluding amounts required to be paid on account of insurance,
taxes, assessments, utility, operating and labor costs and similar charges. In
the case of any lease which is terminable by the lessee upon the payment of a
penalty, such net amount shall also include the amount of such penalty, but no
rent shall be considered as required to be paid under such lease subsequent to
the first date upon which it may be so terminated.

                  "Business Day" means any day except a Saturday, Sunday or
other day on which commercial banks in Houston, Texas are authorized by law to
close.

                  "Change of Control" shall have occurred if (i) any Person or
related Persons constituting a "group" for purposes of Section 13(d) of the
Exchange Act shall have acquired "beneficial ownership" of a majority of the
voting stock of the Issuer, or (ii) during any period of 24 consecutive months,
individuals who were directors of the Issuer at the beginning of the period and
Qualifying Directors, in the aggregate, shall cease to constitute a majority of
the Board of Directors of the Issuer.

Person, whether or not such Debt is assumed by such Person, provided that to the
extent such Debt is not assumed by such Person the amount of such Debt for
purposes of the provisions of this Agreement shall be equal to the lesser of (a)
the amount of Debt secured by such Lien or (b) the value of the asset which
secures such Debt and to the extent such Debt is assumed by such Person the
amount of such Debt for purposes of the provisions of this Agreement shall equal
the amount of such Debt assumed; and (vi) all Debt of others described in (i)
through (v) above directly or indirectly guaranteed by such Person or in respect
of which such Person is otherwise liable, contingently or otherwise; provided,
that the amount of such Debt for the purposes of this Agreement shall be equal

recoverable by natural reservoir energies (including pumping) from the
completion intervals currently open and producing to market. Additional oil and
gas expected to be obtained through the application of fluid injection or other
improved recovery techniques for supplementing the natural forces and mechanisms
of primary recovery will be included as "Proved Developed Producing Reserves"
only after testing by a pilot project or after the operation of an installed
program has confirmed through production response through existing completions
producing to market that increased recovery will be achieved. Proved Developed

time, but generally shall mean those reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively
major expenditure is required for recompletion. Proved Undeveloped Reserves on
undrilled acreage shall be limited to those drilling units offsetting productive
units that are reasonably certain of production when drilled. Proved Undeveloped
Reserves for other undrilled units can be claimed only where it can be
demonstrated with certainty that there is continuity of production from the
existing productive formation. Under no circumstances should estimates for

contemplated, unless such techniques have been proved effective by actual tests
in the area and in the same reservoir.

                                    THE NOTES

                  SECTION 2.01. Sale and Purchase of Notes. The Issuer agrees to
issue and sell to each Purchaser, and subject to the terms and conditions of
this Agreement, each Purchaser, severally and not jointly, agrees to purchase

attached hereto. The purchase price of the Notes to be purchased by each
Purchaser shall be 100% of the principal amount thereof. The Notes to be
purchased by each Purchaser will be dated the date of issue thereof, will mature
on the date set forth therein and will bear interest on the unpaid balance
thereof from the date of issue until the principal thereof shall become due and
payable, at the rate of 7.19% per annum. Interest on the Notes shall be computed
on the basis of a year of 360 days, consisting of 12 30-day months, and accrued
and unpaid interest on the unpaid balance thereof shall be payable semi-annually
on May 15 and November 15 of each year, commencing May 15, 1998, and at

demand, for each day from and including the date payment thereof is due to but
excluding the date of actual payment, at a rate per annum equal to the higher of
(i) 9.19% and (ii) the Prime Rate for such day plus 2%. Whenever any payment of
principal of, or interest on, a Note shall be due on a day which is not a
Business Day, the date for payment thereof shall be extended to the next
succeeding Business Day. If the date for any payment of principal is extended by
operation of law or otherwise, interest thereon will be payable for such
extended time. The Notes will be in registered form substantially in the form of
Exhibit A attached hereto.


   11

                  SECTION 2.02. CLOSING. The sale and purchase of the Notes
shall take place- at the offices of Milbank, Tweed, Hadley & McCloy, 1 Chase
Manhattan Plaza, New York, New York 10005, at 10:00 a.m., New York City time, on
November 18, 1997 or at such other time on such day as may be agreed upon by the
Issuer and the Purchasers (the "Closing"). At the Closing, the Issuer will
deliver to each Purchaser the Note or Notes to be purchased by such Purchaser,
dated the date of the Closing and registered in such Purchaser's name (or in the
name of such Purchaser's nominee), against delivery by such Purchaser to the
Issuer or its order of immediately available funds in the amount of the purchase
price thereof. If at the Closing the Issuer shall fail to tender such Note or
Notes to such Purchaser as provided above, or any of the conditions specified in
Article III shall not have been satisfied or waived, such Purchaser shall, at
its election, be relieved of all further obligations under this Agreement,
without thereby waiving any other rights such Purchaser may have by reason of
such failure or such nonfulfillment.

                  SECTION 2.03. Prepayments. (a) Subject to the provisions of
Section 2.03(e), the Issuer shall pay $20,000,000 of the outstanding principal
amount of the Notes on November 15 of each of the years 2005 through 2008,
inclusive, and shall pay the remaining outstanding principal amount of the Notes
together with all accrued but unpaid interest thereon, and the Notes shall
finally mature, on November 15, 2009.

                  (b) On any date (but in any event not more than four times in
any fiscal year), the Issuer may prepay all or any portion of the Notes,
provided that, simultaneously with any such prepayment, the Issuer shall pay
accrued but unpaid interest and a prepayment charge with respect to Notes being
prepaid equal to the amount (the "Make Whole Amount") not less than zero that is
the excess of:

                  (1) the sum of the Present Values of (i) the aggregate
         principal amount of the Notes being prepaid (assuming the principal
         balance of such Notes payable upon maturity and the required
         prepayments pursuant to Section 2.03(a) are paid when due, without
         regard to the prepayment in respect of which the Make Whole Amount is
         being calculated) and (ii) the amount of interest which would have been
         payable on the principal amount of such Notes (assuming the principal
         balance of such Notes payable upon maturity, the required prepayments
         pursuant to Section 2.03(a) and interest payments pursuant to the terms
         of such Notes are paid when due); over

                  (2) the aggregate principal amount of the Notes being prepaid.

For purposes of the definition of Make Whole Amount, "Present Value" shall be
computed in accordance with generally accepted accounting principles on a
semiannual basis at a discount rate equal to the sum of the Treasury Yield plus
0.50%; and the "Treasury Yield" shall be the yield to maturity implied by (i)
the yields reported, as of 10:00 A.M. (New York City time) on the second
Business Day prior to the date fixed for prepayment, on the display designated
as Bloomberg Financial Markets "Page USD" (or such other display as may replace
Bloomberg Financial Markets "Page USD") for actively traded United States
Treasury securities adjusted to a constant maturity equal to the then remaining
weighted average life of the Notes being prepaid (the "Remaining Life"), or (ii)
if such yields are not reported as of such time or the yields reported as of
such time are not ascertainable, the Treasury Constant Maturity Series Yields
reported, for the latest day for which such yields have been so reported as of
the second Business Day prior to the date fixed for prepayment in Federal
Reserve Statistical Release H.15 (519) (or any comparable successor publication)
for actively traded United States Treasury securities adjusted to a constant
maturity equal to the Remaining Life; provided that if the Remaining Life of the
Notes is not equal to the constant maturity of a United States Treasury


   12

security for which a weekly average yield is given, the Treasury Yield shall be
obtained by linear interpolation (calculated to the nearest one-twelfth of a
year) from the most recent weekly average yield of United States Treasury
securities for which such yields are given having a maturity as close as
possible to the Remaining Life.

                  Prepayments of Notes in accordance with this subsection (b)
shall be made in minimum amounts of $5,000,000 principal amount of Notes and
increments of $1,000,000.

                  (c) The Issuer shall give each Holder at least 20 Business
Days'(but not more than 60 days') notice of any anticipated prepayment of Notes
pursuant to paragraph (b) of this Section 2.03, which notice shall set forth the
date of the prepayment and the anticipated amount of the prepayment applicable
to such Holder's Notes. Any such notice given by the Issuer hereunder shall be
irrevocable. The Issuer shall, at least one Business Day prior to the date of
the prepayment, give immediate notice to each Holder of the Make Whole Amount
applicable to such prepayment, showing the components of the calculation
thereof.

                  (d) In the event of a Change of Control, the Issuer shall
prepay the aggregate principal amount of the Notes of any Holder electing
prepayment, together with accrued and unpaid interest thereon and the Make Whole
Amount with respect thereto. The Issuer shall give notice (the "Change of
Control Notice") to each Holder of a Change of Control within 5 Business Days of
knowledge of such event. The Change of Control Notice shall include a statement
of the date of occurrence of such Change of Control and a description of the
facts known to the Issuer underlying such Change of Control and shall state that
the Issuer is obligated, pursuant to this Section 2.03(d), to purchase Notes in
respect of which a Holder shall elect prepayment. Each Holder electing
prepayment shall notify the Issuer in writing of its election of prepayment (the
"Election Notice") within 30-days of the date of the Change of Control Notice.
The Issuer shall promptly upon receipt of an Election Notice from any Holder
forward a copy of such Election Notice to all other Holders. In the event that a
Change of Control occurs but no Change of Control Notice is given by the Issuer,
a Holder may deliver a notice to the Issuer (a "Purchase Notice") stating that
it is electing to exercise its right to require the Issuer to purchase its
Notes. The Issuer shall forthwith upon receipt of any Purchase Notice give
notice of the receipt of such Purchase Notice (and enclose a copy of such
Purchase Notice) to all other Holders, stating that other Holders may give a
similar notice to the Issuer within 30 days of the date of transmission of the
copy of such Purchase Notice by the Issuer. Prepayments required to be made by
this paragraph (d) shall be made on a date specified by the Issuer by at least 5
Business Days notice to the Holders electing prepayment, which date shall be no
later than 15 days after the earlier of (i) the last day for submission of the
Election Notice or Purchase Notice by any Holder and (ii) the date of receipt by
the Issuer of an Election Notice or Purchase Notice from a Holder such that all
Holders of Outstanding Notes have delivered such Notice to the Issuer.

                  (e) The Issuer will not make any payment of any Note under
this Section 2.03 unless a simultaneous payment is made to all Holders (or in
the case of prepayment under subsection (d) to all Holders electing prepayment)
so as to reduce ratably the obligation of the Issuer under each of the
Outstanding Notes (or, in the case of prepayment under subsection (d), under
each of the Outstanding Notes as to which the Holder has elected prepayment).
The amount of each payment required by subsection (a) shall be reduced ratably
by the aggregate principal amount of Notes prepaid in accordance with subsection
(b) or (d).

                  (f) The Issuer will not, and will not permit any of its
Affiliates to, acquire directly or indirectly by purchase or prepayment or
otherwise any of the Outstanding Notes except by way of payment or prepayment in
accordance with the provisions of the Notes and of this


   13

Agreement. Notes paid or prepaid in full in accordance with this Section 2.03
shall not be deemed Outstanding for any purpose under this Agreement.

                  SECTION 2.04. Maximum Interest Rate. The Issuer, the
Purchasers and all other Holders of the Notes specifically intend and agree to
limit contractually the amount of interest, and all amounts which shall be
deemed to constitute interest under applicable law, payable under this
Agreement, the Notes and all other instruments and agreements related hereto and
thereto to the maximum amount of interest lawfully permitted to be charged under
applicable law. Therefore, none of the terms of this Agreement, the Notes or any
instrument pertaining to or relating to this Agreement or the Notes shall ever
be construed to create a contract to pay interest at a rate in excess of the
maximum rate permitted to be charged under applicable law, and neither the
Issuer nor any other party liable or to become liable hereunder, under the Notes
or under any other instruments and agreements related hereto and thereto shall
ever be liable for interest in excess of the amount determined at such maximum
rate, and the provisions of this Section 2.04 shall control over all other
provisions of this Agreement, the Notes, or any other instrument pertaining to
or relating to the transactions herein contemplated. If any amount of interest
taken or received by any Holder of a Note shall be in excess of said maximum
amount of interest which, under applicable law, could lawfully have been
collected by such Holder incident to such transactions, then such excess shall
be deemed to have been the result of a mathematical error by all parties hereto
and the amount of interest which would otherwise be payable hereunder or under
the Notes shall be automatically reduced to the amount allowed under applicable
law, and such excess shall be credited ratably against and to the extent of the
unpaid principal amount of the Note or Notes held by such Holder, with the
excess, if any, being refunded to the Issuer. All amounts paid or agreed to be
paid in connection with such transactions which would under applicable law be
deemed "interest" shall, to the extent permitted by such applicable law, be
amortized, prorated, allocated and spread throughout the full stated term of
this Agreement. "Maximum rate" as used in this paragraph means, with respect to
each of the Notes, the maximum lawful, nonusurious rates of interest which under
applicable law may be charged to the Issuer from time to time with respect to
such Notes.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

           The Issuer represents and warrants to each Purchaser that:

                  SECTION 4.01. Corporate Existence and Power. The Issuer and
each Subsidiary is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation, and has all
corporate powers and all governmental licenses, authorizations, consents and
approvals required to own its assets and to carry on its business as now
conducted and is duly qualified as a foreign corporation in good standing in
each jurisdiction where the nature of its business or the ownership or leasing
of its Properties requires such qualification, except where the failure to
qualify would not materially and adversely affect the conduct of its business or
the enforceability of contractual obligations of the Issuer. Neither the Issuer
nor any Affiliate is subject to regulation under the Public Utility Holding
Company Act of 1935, the Investment Company Act of 1940, the Transportation Act
(49 U.S.C.), as amended, the Federal Power Act, as amended, or any other law or
regulation the application of which limits the incurrence by the Issuer of Debt
hereunder, including, but not limited to, laws relating to common or contract
carriers or the sale of electricity, gas, steam, water or other public utility
services.

                  SECTION 4.02. Corporate and Governmental Authorization; No
Contravention. The execution, delivery and performance by the Issuer of this
Agreement and the Notes are within the Issuer's corporate powers, have been duly
authorized by all necessary corporate action, require no action by or in respect
of, or filing with, any governmental body, agency or official and do not
contravene, or constitute a default under, any provision of applicable law or
regulation or of the certificate of incorporation or bylaws of the Issuer or of
any agreement or instrument evidencing or governing Debt of the Issuer or any
Affiliate or any other agreement, instrument, judgment, injunction, order or
decree binding upon the Issuer or any Subsidiary or result in the creation or
imposition of any Lien on any asset of the Issuer pursuant to any such
agreement, instrument, judgment, injunction, order or decree.

                  SECTION 4.03. Binding Effect. The Notes and this Agreement
constitute legal, valid and binding obligations of the Issuer enforceable in
accordance with their terms, except as the enforceability thereof may be limited
by (i) bankruptcy, insolvency or similar laws affecting creditors' rights
generally and (ii) equitable principles of general applicability.

                  SECTION 4.04.  Financial Information

                  (a) Audited Financial Statements. The consolidated balance
sheets of the Issuer and its Subsidiaries as of the fiscal years ended December
31, 1994 to 1996 and the related consolidated statements of operations, cash
flows and stockholders' equity for the fiscal years then ended, reported on by
Coopers & Lybrand and set forth in the Offering Memorandum, a copy of which has
been delivered to each of the Purchasers, fairly present, in conformity with
generally accepted accounting principles, the consolidated financial position of
the Issuer and its Subsidiaries as of such dates and their consolidated results
of operations and cash flows for such fiscal years.

                  (b) Reserve Data. There are no statements or conclusions in
the reserve report included in the Offering Memorandum provided to Purchasers
regarding reserves which are based upon or include misleading information or
fail to take into account material information known to the Issuer regarding the
matters reported therein, it being understood that such statements and
conclusions are necessarily based upon professional opinions, estimates and
forecasts, and the Issuer


   16

does not warrant that such opinions, estimates and forecasts will ultimately
prove to have been accurate. Such reserve data has, in the judgment of the
Issuer, been properly compiled from engineering tests conducted in accordance
with prevailing industry standards.

                  (c) The financial projections and estimates and the pro forma
financial statements included in the Offering Memorandum or otherwise furnished
by the Issuer in connection with the Notes and this Agreement have been prepared
by the Issuer in good faith on the basis of information and assumptions that the
Issuer believed to be reasonable as of the date of such information, and no
material assumptions have been omitted as basis for such financial projections
and estimates and pro forma financial statements.

                  (d) Since December 31, 1996, there has been no material
adverse change in the business, Properties, financial position, results of
operations or prospects of the Issuer or the Issuer and its Subsidiaries,
considered as a whole.

                  SECTION 4.05. Full Disclosure. None of the financial
statements and other financial or factual information included in the Offering
Memorandum (excluding estimates, financial projections and pro forma financial
statements) contains any untrue statement of material fact or omits to state a
material fact necessary in order to make the statements contained therein not
misleading. All other financial and reserve information, financial statements
and other documents (excluding estimates, projections and pro forma financial
information) furnished by the Issuer to the Purchasers in connection with the
Notes and this Agreement and set forth on Schedule 4.05 do not and will not
contain any untrue statement of material fact or omit to state a material fact
necessary in order to make the statements contained therein not misleading. The
Issuer has disclosed to the Purchasers in writing any and all facts known to the
Issuer which materially, and adversely affect the business, properties,
operations or condition, financial or otherwise, of the Issuer or the Issuer and
its Subsidiaries, considered as a whole or the Issuer's ability to perform its
obligations under the Notes and this Agreement.

                  SECTION 4.06. Litigation. Except as disclosed on
Schedule 4.06 there is no action, suit or proceeding pending against, or to the
knowledge of the Issuer threatened against or affecting, the Issuer or any of
its Affiliates before any court or arbitrator or any governmental body, agency
or official in which there is a reasonable possibility of an adverse decision
which could individually or in the aggregate materially adversely affect the
financial position of the Issuer or the Issuer and its Subsidiaries, considered
as a whole or which in any manner draws into question the validity of the Notes
and this Agreement.

                  SECTION 4.07. Compliance with ERISA. (a) Each member of the
ERISA Group has fulfilled its obligations under the minimum funding standards of
ERISA and the Internal Revenue Code with respect to each Plan and is in
compliance in all material respects with the presently applicable provisions of
ERISA and the Internal Revenue Code with respect to each Plan. No member of the
ERISA Group has (i) sought a waiver of the minimum funding standard under
Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to
make any contribution or payment to any Plan or Multiemployer Plan, or made any
amendment to any Plan, which, in either case, has resulted or could result in
the imposition of a Lien on Property of the Issuer or any Subsidiary or the
posting of a bond or other security by the Issuer or any Subsidiary under ERISA
or the Internal Revenue Code or (iii) incurred any liability under Title IV of
ERISA (other than a liability to the PBGC for premiums under Section 4007 of
ERISA) which could cause the Issuer or any Subsidiary (whether directly or
jointly and severally with one or more affiliates) to incur any liability.


   17

                  (b) The execution and delivery of this Agreement and the
issuance and sale of the Notes hereunder will not involve any transaction that
is subject to the prohibitions of section 406(a) of ERISA or in connection with
which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the
Internal Revenue Code. The representation by the Issuer in the immediately
preceding sentence is made in reliance upon and subject to the accuracy of the
representation of each Purchaser in Section 7.02 as to the sources of the funds
used to pay the purchase price of the Notes to be purchased by such Purchaser.

                  SECTION 4.08. Environmental Matters. In the ordinary course of
its business, the Issuer considers effects of all existing and applicable
Environmental Laws on the business, operations and properties of the Issuer and
its Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for cleanup or closure of properties currently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses). The Issuer has
reasonably concluded that existing and applicable Environmental Laws are
unlikely to have a material adverse effect on the business, Properties,
financial condition, results of operations or prospects of the Issuer or the
Issuer and its Subsidiaries, considered as a whole. The Issuer and its
Subsidiaries have conducted and are conducting their respective businesses in
compliance with all applicable Environmental Laws, except where the failure to
so comply would not have a material adverse effect on the Issuer or the Issuer
and its Subsidiaries, considered as a whole.

                  SECTION 4.09. Taxes. The Issuer and its Subsidiaries have
filed all United States Federal income tax returns and all other material tax
returns which are required to be filed by them and have paid all taxes due
pursuant to such returns or pursuant to any assessment received by the Issuer or
any Subsidiary. The charges, accruals and reserves on the books of the Issuer
and its Subsidiaries in respect of taxes or other governmental charges are
adequate.

                  SECTION 4.10. Titles, ect. The Issuer and each Subsidiary has
valid and defensible title to its material (individually or in the aggregate)
Petroleum Properties and good, valid, defensible and marketable title to its
other real and personal property, in each case free and clear of all Liens
except Liens expressly permitted by Section 5.10. Each lease under which the
Issuer or any of its Subsidiaries is the lessee which is material to the
business or operations of the Issuer or the Issuer and its Subsidiaries
considered as a whole is valid and subsisting and is in full force and effect.

                  SECTION 4.11. Casualities; Taking of Properties. Since the
date of the reserve data included in the Offering Memorandum, neither the
business nor the Petroleum Properties of the Issuer or any of its Subsidiaries
have been affected as a result of any fire, explosion, earthquake, flood,
drought, windstorm, accident, strike or other labor disturbance, embargo,
requisition or taking of Property or cancellation of contract, permits or
concessions by any domestic or foreign government or any agency thereof, riot,
activities of armed forces or acts of God or of any public enemy, or any other
event the occurrence of which, would have a material adverse effect on the
business, Properties, financial condition, results of operations or prospects of
the Issuer or the Issuer and its Subsidiaries, considered as a whole.

                  SECTION 4.12. Gas Imbalances. There exists no gas imbalances,
take or pay or other prepayments with respect to any Petroleum Properties which
would require the Issuer or any Subsidiary to deliver hydrocarbons produced from
any Petroleum Properties at some future time


   18

without then or thereafter receiving full payment therefor which would be
reasonably likely to have a material adverse effect on the business, Properties,
financial condition, results of operations or prospects of the Issuer or the
Issuer and its Subsidiaries, considered as a whole.

                  SECTION 4.13. Use of Proceeds. The proceeds from the sale of
the Notes pursuant to this Agreement will be used by the Issuer to repay
indebtedness under the Credit Agreement and for general corporate purposes. No
part of the proceeds from the sale of the Notes hereunder will be used, directly
or indirectly, for the purpose of buying or carrying any margin stock within the
meaning of Regulation G of the Board of Governors of the Federal Reserve System
(12 CFR 207), or for the purpose of buying or carrying or trading in any
securities under such circumstances as to involve the Issuer in a violation of
Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a
violation of Regulation T of said Board (12 CFR 220). Margin stock does not
constitute more than 5% of the value of the consolidated assets of the Issuer
and its Subsidiaries and the Issuer does not have any present intention that
margin stock will constitute more than 5% of the value of such assets. As used
in this Section, the terms "margin stock" and "purpose of buying or carrying"
shall have the meanings assigned to them in said Regulation G.

                  SECTION 4.14. Offering of the Notes. Neither the Issuer nor
any Person acting on behalf of the Issuer has, directly or indirectly, offered
any of the Notes or any similar security of the Issuer for sale to, or solicited
any offers to buy any thereof from, or otherwise approached or negotiated with
respect thereto with, anyone other than the Purchasers and not more than 75
other institutional investors, each of whom were offered a portion of the Notes
for purposes of investment and not for distribution. Neither the Issuer nor any
Person acting on behalf of the Issuer has taken or will take any action which
would cause the offer, issuance or sale of any Note to any Purchaser to violate
the provisions of the Securities Act of 1933, as amended, or any other
securities or blue sky laws of any applicable jurisdiction or subject the
issuance or sale of the Notes to the registration requirements of Section 5 of
said Securities Act.

                  SECTION 4.15. Ownership of Subsidiaries. Schedule 4.15 sets
forth a list of each Subsidiary of the Issuer and its jurisdiction of
incorporation. All of the issued shares of capital stock of such Subsidiary have
been duly and validly authorized and issued, are fully paid and nonassessable,
and are owned directly or indirectly by the Issuer, free and clear of all Liens
and restrictions on transferability or voting.



                                    ARTICLE V

                                    COVENANTS

                  The Issuer agrees that, so long as any amount payable under
any Note or this Agreement remains unpaid, it will, and will cause each of its
Subsidiaries to, perform and comply with each of the following covenants, unless
such performance and compliance shall have been specifically waived in writing
by the Required Lenders:


   19

                  SECTION 5.01. Information. The Issuer will deliver to each of

         year and the related consolidated statements of operations, cash flows
         and stockholders' equity for such fiscal year, setting forth in each
         case in comparative form the figures for the previous fiscal year, all
         reported on in a manner acceptable to the Securities and Exchange
         Commission by Coopers & Lybrand or other independent public accountants
         of nationally recognized standing;

                  (b) as soon as available and in any event within 60 days after
         the end of each of the first three quarters of each fiscal year of the

         as of the end of such quarter and the related consolidated statements
         of operations and cash flows for such quarter and for the portion of
         the Issuer's fiscal year ended at the end of such quarter, setting
         forth in each case in comparative form the figures for the
         corresponding quarter and the corresponding portion of the Issuer's
         previous fiscal year, all certified (subject to normal year-end
         adjustments) as to fairness of presentation, generally accepted
         accounting principles and consistency by the chief financial officer or
         the chief accounting officer or treasurer of the Issuer;

         financial statements, and (ii) stating whether any Default then exists,
         setting forth the details thereof and the action which the Issuer is
         taking or proposes to take with respect thereto;

                  (d) within five days after any Executive Officer of the Issuer

         officer or treasurer of the Issuer setting forth the details thereof

         have filed with the Securities and Exchange Commission;

                  (g) if and when any member of the ERISA Group (i) gives or is
         required to give notice to the PBGC of any "reportable event" (as
         defined in Section 4043 of ERISA and the regulations thereunder) with
         respect to any Plan which might constitute grounds for a termination of
         such Plan under Title IV of ERISA, or any Executive Officer of the
         Issuer or any Subsidiary knows that the plan administrator of any Plan
         has given or is required to give notice of any such reportable event, a
         copy of the notice of such reportable event given or required to be

                  SECTION 5.02. Payment of Obligations. The Issuer will pay and
discharge, and will cause each Subsidiary to pay and discharge, at or before
maturity, all their respective material obligations and liabilities, including,
without limitation, tax liabilities, except where, the same may be contested in

business in good working order and condition, ordinary wear and tear excepted.
The Issuer will operate, or will use its best efforts to cause a third party
operator to operate, all Petroleum Properties in a prudent manner, and will

Persons engaged in the same or similar businesses and similarly situated.

                  SECTION 5.08. Engineering Reports

                  (a) On or before April 10, 1998, and thereafter by April 10th
of each subsequent year, the Issuer shall furnish to each of the Holders a
report in form and substance reasonably satisfactory to the Required Lenders
prepared by or under the supervision of a petroleum engineer who may be an
employee of the Issuer, which shall evaluate all net Proved Reserves owned by
the Issuer and its Subsidiaries as of the preceding December 31 and which shall
set forth the information necessary to determine the Present Value of Proved
Reserves as of such date.

                  (b) Together with the Reserve Report furnished pursuant to
subsection (a), the Issuer shall furnish to each of the Holders a review report
thereon in form and substance reasonably satisfactory to the Required Lenders by
Miller & Lents, Ltd. or other independent petroleum engineers of nationally
recognized standing.

                  SECTION 5.09. Asset Coverage Ratio. (a) The ratio of (i)
Present Value of Proved Reserves plus Adjusted Cash to (ii) Debt and Other
Liabilities shall at all times be not less than 1.5:1;

                  (b) The Present Value of Proved Reserves will be determined
and adjusted periodically as follows:

                  (i) The calculation of Present Value of Proved Reserves will
         be determined from the most recent Reserve Report.

                  (ii) Upon any sale by the Issuer or any Subsidiary of any
         Petroleum Property including but not limited to a sale of a lesser
         interest such as a royalty or a net profit interest to the extent the
         sale of such lesser interest is not considered to create a Lien (other
         than the sale of hydrocarbons after severance occurring in the ordinary
         course of the Issuer's business), the calculation of Present Value of
         Proved Reserves shall be reduced, effective on the date of consummation
         of such sale, by an amount equal to the Present Value of Proved
         Reserves attributable to Proved Reserves included in such sale.

                  (iii) Immediately upon acquisition or development by the
         Issuer or any Subsidiary of any Petroleum Property owned directly by
         the Issuer or any Subsidiary and not reflected in the most recent
         Reserve Report, the calculation of Present Value


   22

         of Proved Reserves shall be increased in an amount equal to the Present
         Value of Proved Reserves attributable to such Petroleum Property.

                  SECTION 5.10. Liens. The Issuer will not, and will not permit
any Subsidiary to, create, incur, assume or suffer to exist any Lien on any of
its Properties (now owned or hereafter acquired), except:

                  (a)  Excepted Liens;

                  (b) Liens existing on the Closing Date and listed on Schedule
         5.10, but not any renewals and extensions thereof;

                  (c) a Lien existing on any asset prior to the acquisition
         thereof by the Issuer or any of its Subsidiaries but not created in
         contemplation of such acquisition;

                  (d) a Lien on any asset not previously owned by the Issuer or
         any Subsidiary securing Debt incurred or assumed for the purpose of
         financing any part of the cost of acquiring such asset, provided that
         such Lien attaches to such asset concurrently with or within 90 days
         after the acquisition thereof;

arrangement with, any Affiliate; provided, however, that the foregoing
provisions of this Section shall not prohibit (a) the Issuer or any Subsidiary

therewith, extending credit or making payments, or from making payments for
services rendered by any Affiliates, if such sales or purchases are made or such
services are rendered in the ordinary course of business and on terms and
conditions at least as favorable to it as the terms and conditions which would
apply in a similar transaction with a Person not an Affiliate, (b) the Issuer
from making payments of principal, interest and premium on any Debt of the
Issuer held by an Affiliate if the terms of such Debt are substantially as
favorable to the Issuer as the terms which could have been obtained at the time
of the creation of such Debt from a lender which was not an Affiliate and are
otherwise in accordance with this Agreement, (c) the Issuer or any Subsidiary
from participating in, or effecting any transaction in connection with, any
joint enterprise or other joint arrangement with any Affiliate if it
participates or effects any such transaction in the ordinary course of its
business and on a basis no less advantageous than the basis on which such
Affiliate participates or (d) the Issuer or any Wholly-Owned Subsidiary from
engaging in any of the above listed activities with any other Wholly-Owned
Subsidiary or any Wholly-Owned Subsidiary with the Issuer.

         cash from operating activities of the Issuer and its Consolidated
         Subsidiaries for such period, as the same is, or would in accordance
         with generally accepted accounting principles be set forth in a
         statement of cash flows for such period, plus to the extent deducted in
         determining such net cash from operating activities, the sum of (x)

         expense.

                  (iii) "Consolidated Interest Expense" means, for any period,
         the interest expense of the Issuer and its Consolidated Subsidiaries
         determined on a consolidated basis for such period in accordance with
         generally accepted accounting principles.

                  (iv) "Consolidated Subsidiaries" means at any date any
         Subsidiary or other entity the accounts of which would in accordance
         with generally accepted accounting principles be consolidated with
         those of the Issuer in its consolidated financial statements if such
         statements were prepared as of such date.

                  SECTION 5.13. Consolidations, Mergers and Sales of Asset. (a)
Without limiting the applicability of Section 2.03(d), the Issuer will not
consolidate or merge with or into any other Person or sell, lease or otherwise
transfer, directly or indirectly, all or substantially all of its assets to any
other Person unless (i) immediately after giving effect to such consolidation,
merger, sale, lease or other transfer, no Default shall exist and the Issuer
would be in compliance with the provisions of Section 5.12 (assuming that the
date of any determination hereunder were the end of a fiscal quarter of the
Issuer), (ii) such Person shall be a corporation organized and existing under
the laws of the United States of America or any state therein or the District of
Columbia and (iii) all of the obligations of the Issuer under the Notes and this
Agreement shall have been expressly assumed in writing by the Person formed by
such consolidation, or into which the Issuer shall have been merged, or which
shall have acquired such assets.

                  (b) The Issuer will not, and will not permit any Subsidiary
to, make any Asset Disposition to any Person unless such Asset Disposition is
upon fair and reasonable terms no less favorable to the Issuer or such
Subsidiary than would obtain in a comparable arm's-length transaction with a
Person which is not an Affiliate; provided that, this Section 5.13(b) shall not
limit the transactions permitted with Affiliates provided under Section 5.11
hereof.

                  SECTION 5.14. Subsidiary Debt. The Issuer will not permit any
Subsidiary to incur, create, assume, guarantee or in any other manner become

which such lender or investor is a party providing for the leasing by the Issuer
or any of its Subsidiaries for a period of more than three years (including all
renewals and extensions) of real or personal property that has been or is to be
sold or transferred by the Issuer or any of its Subsidiaries to such lender or
investor or to any Person to whom funds have been or are to be advanced by such
lender or investor on the security of such property or rental obligations of the
Issuer or any of its Subsidiaries, unless the Issuer or such Subsidiary would be
entitled, pursuant to Section 5.10(f), to incur Debt in a principal amount equal
to or exceeding the Attributable Debt in respect of such arrangement, secured by
a Lien on the property to be leased, without any violation of Section 5.09 or

         have become liable to pay under Title IV of ERISA which failure to pay

         respect of such amount or amounts, except for any such failure which is
         being contested in good faith through appropriate proceedings, so long

         occur a complete or partial withdrawal from, or a default, within the
         meaning of Section 4219(c)(5) of ERISA, with respect to, one or more

separate accounts maintained by it or for the account of one or more pension or
trust funds, in each case for investment and not with a view to the distribution

                  (b) the Source is a separate account that is maintained solely
         in connection with such Purchaser's fixed contractual obligations under
         which the amounts payable, or credited, to any employee benefit plan
         (or its related trust) that has any interest in such separate account
         (or to any participant or beneficiary of such plan (including any

         performance of the separate account; or

                  (c) the Source is either (i) an insurance company pooled
         separate account, within the meaning of PTE 90-1 (issued January 29,

         allocated to such pooled separate account or collective investment
         fund; or

                  (d) the Source constitutes assets of an "investment fund"
         (within the meaning of Part V of the QPAM Exemption) managed by a
         "qualified professional asset manager" or "QPAM" (within the meaning of
         Part V of the QPAM Exemption), no employee benefit plan's assets that
         are included in such investment fund, when combined with the assets of
         all other employee benefit plans established or maintained by the same
         employer or by an affiliate (within the meaning of Section V(c) of the
         QPAM Exemption) of such employer or by the same employee organization
         and managed by such QPAM, exceed 20% of the total client assets managed
         by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption
         are satisfied, neither the QPAM nor a person controlling or controlled
         by the QPAM (applying the definition of "control" in Section V(e) of
         the QPAM Exemption) owns a 5% or more interest in the Issuer and (i)
         the identity of such QPAM and (ii) the names of all employee benefit

         separate account or trust fund comprised of one or more employee
         benefit plans, each of which has been identified to the Issuer in
         writing pursuant to this paragraph (f); or

                  (g) the Source does not include assets of any employee benefit
         plan, other than a plan exempt from the coverage of ERISA.

As used in this Section 7.02, the terms "employee benefit plan", "governmental
plan", "party in interest" and "separate account" shall have the respective
meanings assigned to such terms in Section 3 of ERISA.

Issuer together with an opinion of counsel to the effect that the foregoing
legend is no longer required under applicable securities laws obtain a like Note
in exchange for its Note without such legend.

the right to be indemnified hereunder for its own gross negligence or willful
misconduct as determined by a court of competent jurisdiction.

                  SECTION 8.04. Amendments and Waivers. (a) Any provision of
this Agreement or the Notes may be amended or waived if, and only if, such
amendment or waiver is in writing and is signed by the Issuer and the Required
Lenders; provided that no such amendment or waiver shall, unless signed by all
Holders of Outstanding Notes, (i) change the principal of or rate of interest on
any Note, the Make Whole Amount or any other amount payable hereunder, (ii)
waive or change the date fixed for any payment of principal of or interest on
any Note or the Make Whole Amount hereunder, or (iii) change the percentage of
Holders that shall be required for the Holders to take any action under this
Section or any other provision of this Agreement; and provided further that no
such amendment will change the principal amount of Notes to be purchased by any
Purchaser hereunder without the consent of such Purchaser.

                  (b) The Issuer will provide each Holder (irrespective of the
amount of Notes then owned by it) with sufficient information, sufficiently far
in advance of the date a decision is required, to enable such Holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof or of the Notes. The
Issuer will deliver executed or true and correct copies of each amendment,
waiver or consent effected pursuant to the provisions of this Section 8.04 to
each Holder promptly following the date on which it is executed and delivered
by, or receives the consent or approval of, the requisite Holders.

                  (c) The Issuer will not directly or indirectly pay or cause to
be paid any remuneration, whether by way of supplemental or additional interest,
fee or otherwise, or grant any security, to any Holder as consideration for or
as an inducement to the entering into by any Holder or any waiver or amendment
of any of the terms and provisions hereof unless such remuneration is
concurrently paid, or security is concurrently granted, on the same terms,
ratably to each Holder even if such Holder did not consent to such waiver or
amendment.

                  SECTION 8.05. New York Law. This Agreement and each Note shall
be construed in accordance with and governed by the law of the State of New
York.

                  SECTION 8.06. Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Issuer may not assign or transfer any of
its rights or obligations under this Agreement.


   30

                  SECTION 8.07. Form, Registration, Transfer and Exchange of the
Notes; Transferees. (a) The Notes issuable under this Agreement shall be
registered notes substantially in the form of Exhibit A hereto and shall be
issued in denominations of $1,000,000 and any larger multiple of $50,000 (except
as may otherwise be required as a result of prepayments of portions of Notes
pursuant to Section 2.03). The Issuer shall keep at its principal office a
register in which the Issuer shall provide for the registration of the transfers
of Notes. The Issuer's principal office for such purposes shall be maintained in
the continental United States and, until further notice, will be maintained at
the address specified pursuant to Section 8.01. Upon surrender of any Note at
such office for registration of transfer, the Issuer shall execute and deliver,
at its expense, one or more new Notes of a like aggregate unpaid principal
amount. Each such new Note shall be registered in the name of the designated
transferee or transferees (or its nominee or nominees). At the option of the
Holder of any Note such Note may be exchanged for other Notes of any authorized
denominations, of a like aggregate unpaid principal amount upon surrender of the
Note to be exchanged at the principal office of the Issuer. Whenever any Notes
are so surrendered for exchange, the Issuer shall execute and deliver, at its
expense, the Notes which the Holder thereof making the exchange is entitled to
receive. Every Note presented or surrendered for registration of transfer shall
be duly endorsed, or be accompanied by a written instrument of transfer duly
executed by the registered Holder or his attorney duly authorized in writing.
Any Note or Notes issued in exchange for any Note or upon transfer thereof shall
carry the rights to unpaid interest and interest to accrue which were carried by
the Note so exchanged or transferred, and neither gain nor loss of interest
shall result from any such transfer or exchange. Upon the written request of any
Holder, the Issuer shall promptly forward to such Holder the names and addresses
of all other Holders and the principal amount of Notes held by such Holders.
Upon receipt by the Issuer of evidence reasonably satisfactory to it of the
ownership of and loss, theft, destruction or mutilation of any Note and (i) in
case of loss, theft, or destruction, of indemnity reasonably satisfactory to it
(provided that, with respect to Institutional Investors and their nominees, such
Person's agreement of indemnity shall be deemed to be satisfactory) or (ii) in
the case of mutilation, upon surrender and cancellation thereof, the Issuer, at
its expense, will execute and deliver, in lieu thereof, a new Note of like tenor
and dated and bearing interest from the date to which interest has been paid on
such lost, stolen, destroyed or mutilated Note.

                  SECTION 8.08. Persons Deemed Owners. Prior to due presentment
for registration of transfer, the Issuer may treat the Person in whose name any
Note is registered as the owner and holder of such Note for the purpose of
receiving payment of principal of and interest and premium on such Note and for
all other purposes whatsoever, whether or not such Note is or shall be overdue,
and the Issuer shall not be affected by notice to the contrary.

                  SECTION 8.09. Home Office Payment. The Issuer agrees that, so
long as a Purchaser listed on the signature pages hereof or its nominee shall
hold any of the Notes, it will make payments of principal of and interest and
Make Whole Amounts (if any) on such Notes not later than 12:00 noon, New York
City time, on the date such payment is due, in immediately available funds, at
the address specified for such purpose on Schedule A or such other account or
address (in the United States of America) as such Purchaser may designate in
writing, notwithstanding any contrary provisions contained herein or in the
Notes and without any requirement of surrendering the Notes (except that, upon
the written request of the Issuer, any Note that has been paid or prepaid in
full shall be surrendered for cancellation to the Issuer at its principal office
maintained by the Issuer pursuant to Section 8.07). Each Purchaser agrees that,
before selling or otherwise transferring any Note, it will make a notation
thereon of all principal payments previously made thereon and of the date to
which interest thereon has been paid. As to any subsequent Holder, the Issuer
will make payments of principal of and interest on the Notes held by such Holder
not later than 12:00 noon, local time, to a place within the United States on
the date such payment is due, in immediately


   31

available funds, by credit to the account designated by such Holder or at the
option of such Holder by a check mailed or delivered to the address designated
by such Holder.

                  SECTION 8.10. Substitution. Each Purchaser may by notice to
the Issuer substitute any of its wholly-owned subsidiaries as a Purchaser
hereunder. Such notice shall be signed by such Purchaser and such wholly-owned
subsidiary, shall contain such wholly-owned subsidiary's agreement to be bound
by this Agreement and shall contain confirmation by such wholly-owned subsidiary
of the accuracy with respect to it of the representations set forth in Article
VII (subject to any exception necessary to reflect the intention, if any, of
such wholly-owned subsidiary to transfer to such Purchaser at a subsequent date
all or any of the Notes to be acquired by such wholly-owned subsidiary). The
Issuer agrees that, upon receipt of such notice, all references to "Purchaser"
hereunder (other than this Section 8.10) shall include a reference to such
wholly-owned subsidiary and that such wholly-owned subsidiary shall have the
right to transfer the Notes acquired by it hereunder to a Purchaser subsequent
to such purchase. In the event that a wholly-owned subsidiary is substituted for
a Purchaser in accordance with this Section 8.10 and thereafter transfers its
Notes or any portion thereof to such Purchaser, the term "Purchaser" shall be
deemed to refer to such wholly-owned subsidiary only if it retains any portion
of the Notes, and shall refer to such Purchaser to the extent such Purchaser
owns all or any portion of the Notes, and such Purchaser and such wholly-owned
subsidiary (if it retains any Notes) shall each have all the rights which an
original purchaser of Notes has under this Agreement.

                  SECTION 8.11. Credit Decision. Each Purchaser acknowledges
that it has, independently and without reliance upon any other Purchaser, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Purchaser
also acknowledges that it will, independently and without reliance upon any
other Purchaser, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under the Notes and this Agreement.

                  SECTION 8.12. Counterparts; Integration; Effectiveness;
Severability. (a) This Agreement may be signed in any number to counterparts,
each of which shall be an original, and all of which taken together shall
constitute a single agreement, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Agreement constitutes the entire
agreement and understanding among the parties hereto and supersedes any and all
prior agreements and understandings, oral or written, relating to the subject
matter hereof. This Agreement shall become effective when the Issuer shall have
received counterparts hereof signed by all of the parties hereto (or, in the
case of any Purchaser as to which an original executed counterpart shall not
have been received, the Issuer shall have received from such Purchaser an
executed counterpart hereof by facsimile by such Purchaser).

                  (b) In case any provision in this Agreement or any Note shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired thereby
and such provision shall be ineffective only to the extent of such invalidity,
illegality or unenforceability.

                  SECTION 8.13. SUBMISSION TO JURISDICTION. THE ISSUER HEREBY
SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT
FOR THE SOUTHERN DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN
THE CITY OF NEW YORK FOR PURPOSES OF ALL LEGAL PROCEEDINGS WHICH MAY ARISE
HEREUNDER OR UNDER THE NOTES. THE ISSUER IRREVOCABLY WAIVES TO THE FULLEST
EXTENT PERMITTED BY LAW,


   32

ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF
ANY SUCH PROCEEDINGS BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH
PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.
THE ISSUER HEREBY CONSENTS TO PROCESS BEING SERVED IN ANY SUCH PROCEEDING BY THE
MAILING OF A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO
ITS ADDRESS SPECIFIED PURSUANT TO SECTION 8.01 OR IN ANY OTHER MANNER PERMITTED
BY LAW.

                  SECTION 8.14. Confidentiality. For the purposes of this
Section 8.14, "Confidential Information" means information delivered to a Holder
by or on behalf of the Issuer or any Subsidiary in connection with the
transactions contemplated by or otherwise pursuant to this Agreement that is
proprietary in nature and that was clearly marked or labeled or otherwise
adequately identified when received by such Holder as being confidential
information of the Issuer or such Subsidiary, provided that such term does not
include information that (a) was publicly known or otherwise known to such
Holder prior to the time of such disclosure, (b) subsequently becomes publicly
known through no act or omission by such Holder or any person acting on its
behalf, (c) otherwise becomes known to such Holder other than through disclosure
by the Issuer or any Subsidiary or (d) constitutes financial statements
delivered to such Holder under Section 5.01 that are otherwise publicly
available. Each Holder will maintain the confidentiality of such Confidential
Information in accordance with procedures adopted by such Holder in good faith
to protect confidential information of third parties delivered to it, provided
that such Holder may deliver or disclose Confidential Information to (i) its
directors, trustees, officers, employees, agents, attorneys and affiliates (to
the extent such disclosure reasonably relates to the administration of the
investment represented by Notes held by it), (ii) its financial advisors and
other professional advisors who agree to hold confidential the Confidential
Information substantially in accordance with the terms of this Section 8.14,
(iii) any other holder of any Note, (iv) any Institutional Investor to which
such Holder sells or offers to sell such Note or any part thereof or any
participation therein (if such Person has agreed in writing prior to its receipt
of such Confidential Information to be bound by the provisions of this Section
8.14), (v) any federal or state regulatory authority having jurisdiction over
such Holder, (vi) the National Association of Insurance Commissioners or any
similar organization, or any nationally recognized rating agency that requires
access to information about such Holder's investment portfolio, or (vii) any
other Person to which such delivery or disclosure may be necessary or
appropriate (w) to effect compliance with any law, rule, regulation or order
applicable to such Holder, (x) in response to any subpoena or other legal
process, (y) in connection with any litigation to which such Holder is a party
or (z) if an Event of Default has occurred and is continuing, to the extent such
Holder may reasonably determine such delivery and disclosure to be necessary or
appropriate in the enforcement or for the protection of the rights and remedies
under its Notes and this Agreement. Each holder of a Note, by its acceptance of
a Note, will be deemed to have agreed to be bound by and to be entitled to the
benefits of this Section 8.14 as though it were a party to this Agreement. On
reasonable request by the Issuer in connection with the delivery to any holder
of a Note of information required to be delivered to such holder under this
Agreement or requested by such holder (other than a holder that is a party to
this Agreement or its nominee), such holder will enter into an agreement with
the Issuer embodying the provisions of this Section 8.14.

   33

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective authorized officers as of the
date first above written.

                  FOR VALUE RECEIVED, the undersigned, CABOT OIL & GAS
CORPORATION (herein called the "Issuer"), a corporation organized and existing
under the laws of the State of Delaware, hereby promises to pay to
[___________________________], or registered assigns, the principal sum of
[___________________________] DOLLARS on November 15, 2009, with interest
(computed on the basis of a 360-day year of twelve 30-day months) (a) on the
unpaid balance thereof at the rate of 7.19% per annum from the date hereof,
payable semiannually, on the 15th day of May and November in each year,
commencing May 15, 1998, until the principal hereof shall have become due and
payable, and (b) to the extent permitted by law on any overdue payment
(including any overdue prepayment) of principal, any overdue payment of interest
and any overdue payment of any Make Whole Amount (as defined in the Note
Purchase Agreement referred to below), payable semiannually as aforesaid (or, at
the option of the registered holder hereof, on demand), at a rate per annum from
time to time equal to the higher of (i) 9.19% or (ii) the Prime Rate (as defined
in said Note Purchase Agreement) for such day plus 2%.

                  Payments of principal of, interest on and any Make Whole
Amount with respect to this Note are to be made in lawful money of the United
States of America as provided in Section 8.09 of the Note Purchase Agreement
referred to below.

                  This Note is one of a series of Notes (herein called the
"Notes") issued pursuant to the Note Purchase Agreement, dated as of November
14, 1997 (as from time to time amended, the "Note Purchase Agreement"), between
the Issuer and the Purchasers named therein and is entitled to the benefits
thereof. Each holder of this Note will be deemed, by its acceptance hereof, (i)
to have agreed to the confidentiality provisions set forth in Section 8.14 of
the Note Purchase Agreement and (ii) to have made the representation set forth
in Article VII of the Note Purchase Agreement.

                  This Note is a registered Note and, as provided in the Note
Purchase Agreement, upon surrender of this Note for registration of transfer,
duly endorsed, or accompanied by a written instrument of transfer duly executed,
by the registered holder hereof or such holder's attorney duly authorized in
writing, a new Note for a like principal amount will be issued to, and
registered in the name of, the transferee. Prior to due presentment for
registration of transfer, the Issuer may treat the person in whose name this
Note is registered as the owner hereof for the purpose of receiving payment and
for all other purposes, and the Issuer will not be affected by any notice to the
contrary.

                  The Issuer will make required prepayments of principal on the
dates and in the amounts specified in the Note Purchase Agreement. This Note is
also subject to optional prepayment, in whole or from time to time in part, at
the times and on the terms specified in the Note Purchase Agreement, but not
otherwise.


   36

                  If an Event of Default, as defined in the Note Purchase
Agreement, occurs and is continuing, the principal of this Note may be declared
or otherwise become due and payable in the manner, at the price (including any
applicable Make Whole Amount) and with the effect provided in the Note Purchase
Agreement.

                  This Note shall be construed in accordance with and governed
by the law of the State of New York.
