      Not applicable

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

      On April 9 and April 15, 1997, the Company consummated the acquisition
(the "Acquisition") of the oil and gas properties (the "Acquired Properties")
and associated working capital owned by partnerships and other entities (the
"Sellers") managed or sponsored by Torch Energy Advisors Incorporated ("Torch").
The Company agreed to purchase the Acquired Properties and working capital for
$188.3 million effective as of July 1, 1996 (the "Effective Date"), plus a
contingent payment of up to $9.0 million ("Contingent Payment") to be paid on
May 10, 1997, the actual amount of which will be based on 1997 gas prices. The
purchase price, after making adjustments for distributions paid to Sellers from
the Effective Date until the closing date, was $141.8 million, plus the
Contingent Payment. The Sellers are identified in the Acquisition Agreement
included as Exhibit Number 2.2 to the Registration Statement which agreement is
incorporated herein by reference.

      The Company financed the purchase price of the Acquired Properties and
related fees, and the repayment of $12.0 million of indebtedness under a
previously existing credit agreement, with $34,192,891 from the issuance and
sale to the public of 4,411,986 shares of the Company's common stock, par value
$.01 per share ("Common Stock"), such shares including the sale of 11,986 shares
of Common Stock (the "Over-Allotment Shares") issued upon exercise of an
over-allotment option granted to the underwriters, (ii) $97.0 million from the
issuance and sale to the public of $100.0 million of the Company's 10-7/8%
Senior Subordinated Notes due 2007 (the "Notes") and (iii) borrowings under a
new credit facility (the "New Credit Facility") with Morgan Guaranty Trust
Company of New York ("Morgan Guaranty"), as Agent thereunder. The sale to 
                                       2
<PAGE>
the public of such Common Stock and Notes, and the execution and delivery of the
New Credit Facility, closed simultaneously with the purchase of the Acquired
Properties on April 9, 1997 (except for the sale of the Over-Allotment Shares,
which closed on April 14, 1997).

      As of June 30, 1996, estimated net proved reserves attributable to the
Acquired Properties were 39.2 million barrels of oil equivalent (determined
using the ratio of six thousand cubic feet of gas to one barrel of oil,
condensate or natural gas liquids), with 89% of such reserves being proved
developed and 59% of such reserves being natural gas. The Acquired Properties
had a pre-tax, present value of future net cash flows from estimated proved
reserves (discounted at 10% and calculated in accordance with standards
established by the Securities and Exchange Commission) of $212.0 million as of
June 30, 1996. For further information with respect to the Acquired Properties,
see "Prospectus Summary," "Risk Factors" and "Business and Properties," as set
forth in the Prospectus, which sections are herein incorporated by reference.

      Pursuant to agreements with Torch and its subsidiaries, Torch administers
certain business activities of the Company. Torch is primarily engaged in the
business of providing management and advisory services relating to oil and gas
assets for institutional and public investors. For information on relationships
between the Sellers, the Company and Torch, see "Risk Factors - Conflicts of
Interest" and "Management - Transactions with Related Persons" as set forth in
the Prospectus, which sections are herein incorporated by reference.

      On April 21, 1997, the Company entered into another credit facility with
Morgan Guaranty, as Administrative Agent thereunder, replacing its obligations
under the New Credit Facility and adding certain subsidiaries of the Company as
guarantors of indebtedness of the Company thereunder, and entered into a
supplemental indenture which added certain subsidiaries of the Company as
guarantors of the Company's Notes and obligations under the indenture pursuant
to which the Notes were issued.

      THIS FIRST  SUPPLEMENTAL  INDENTURE  dated as of April 21, 1997 is among
BELLWETHER  EXPLORATION COMPANY, a Delaware  corporation (the "Company"),  the
SUBSIDIARY GUARANTORS (as defined herein) and BANK OF MONTREAL TRUST COMPANY, a
New York trust company (the "Trustee").

                             RECITALS OF THE COMPANY

      The Company and various Subsidiaries, specified as Subsidiary Guarantors
have duly authorized the creation of an issue of 10-7/8 % Senior Subordinated
Securities due 2007 (the "Securities"), in accordance with the terms of the
Indenture dated as of April 9, 1997 (such Indenture as the same has been
supplemented or amended heretofore being sometimes referred to herein as the
"Original Indenture"), among the Company, the Subsidiary Guarantors and the
Trustee.

      The Securities are guaranteed by the Subsidiary Guarantors (as defined in
the Indenture) on the terms provided in the Indenture.

      It is deemed desirable to supplement and amend the Original Indenture to

sometimes referred to herein as the "Indenture").

      Article IX, Section 9.1(vii) of the Original Indenture provides that under
certain conditions the Company, each of the Subsidiary Guarantors and Trustee,
may, without the consent of any Holders, at any time and from time to time,
enter into one or more indentures supplemental thereto, in form satisfactory to
the Trustee, for the purpose, inter alia, of adding any Restricted Subsidiary as
an additional Subsidiary Guarantor as provided in Section 10.13(i) of the
Original Indenture.

      In addition, Article X, Section 10.13(i) of the Original Indenture
requires that each Person that becomes, or comes into existence as, a Restricted
Subsidiary after the date of the Original Indenture, prior to its incurrence of
any obligations that guarantee or secure any other Indebtedness of the Company,
to execute and deliver a supplemental indenture to the Original Indenture
agreeing to be bound by those terms applicable to a Subsidiary Guarantor and
providing for a Subsidiary Guarantee of the Securities by such Restricted
Subsidiary.

      All things necessary to authorize the execution and delivery of this First
Supplemental Indenture, to effect the modifications of the Original Indenture
provided for in this First Supplemental Indenture, and to make the Original
Indenture, as supplemented and amended by this First Supplemental Indenture, a
valid agreement of the Company, in accordance with its terms, have been done.

      NOW, THEREFORE, in consideration of the premises and the purchase of the
Securities by the Holders, the Company, the Subsidiary Guarantors and the
Trustee mutually covenant and agree for the equal and proportionate benefit of
the respective Holders from time to time of the Securities as follows:

                                    EXHIBIT A

      The form of notation to be set forth on each Security relating to the
Subsidiary Guarantees shall be in substantially the following form:

                              SUBSIDIARY GUARANTEES

      Subject to the limitations set forth in the Indenture, the initial
Subsidiary Guarantors and, if any, all additional Subsidiary Guarantors (as
defined in the Indenture referred to in the Security upon which this notation is
endorsed and each being hereinafter referred to as a "Subsidiary Guarantor,"
which term includes any additional or successor Subsidiary Guarantor under the
Indenture) have, jointly and severally, unconditionally guaranteed (a) the due
and punctual payment of the principal of (and premium, if any) and interest on
the Securities, whether at maturity, acceleration, redemption or otherwise, (b)
the due and punctual payment of interest on the overdue principal of and
interest on the Securities, if any, to the extent lawful, (c) the due and
punctual performance of all other obligations of the Company to the Holders or
the Trustee, all in accordance with the terms set forth in the Indenture, and
(d) in case of any extension of time of payment or renewal of any Securities or
any of such other obligations, the same will be promptly paid in full when due
or performed in accordance with the terms of the extension or renewal, whether
at Stated Maturity, by acceleration or otherwise.

      The obligations of each Subsidiary Guarantor are limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any
collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under
its Subsidiary Guarantee or pursuant to its contribution obligations under the
Indenture, result in the obligations of such Subsidiary Guarantor under the
Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal or state law. Each Subsidiary Guarantor that makes a
payment or distribution under a Subsidiary Guarantee shall be entitled to a
contribution from each other Subsidiary Guarantor in a pro rata amount based on
the Adjusted Net Assets of each Subsidiary Guarantor.

      The obligations of the Subsidiary Guarantors to the Holders or the Trustee
pursuant to the Subsidiary Guarantees and the Indenture are expressly
subordinate to all Guarantor Senior Indebtedness to the extent set forth in
Article XIII of the Indenture and reference is made to such Indenture for the
precise terms of such subordination.

      No stockholder, officer, director, employee, incorporator or Affiliate as
such, past, present or future, of any Subsidiary Guarantor shall have any
personal liability under its Subsidiary Guarantee by reason of his or its status
as such stockholder, officer, director, employee, incorporator or Affiliate, or
any liability for any obligations of any Subsidiary Guarantor under the
Securities or the Indenture or for any claim based on, in respect of, or by
reason of such obligations or their creation.

      Any Subsidiary Guarantor may be released from its Subsidiary Guarantee
upon the terms and subject to the conditions provided in the Indenture.

      All terms used in this notation of Subsidiary Guarantee which are defined
in the Indenture referred to in this Security upon which this notation of
Subsidiary Guarantees is endorsed shall have the meanings assigned to them in
such Indenture.

                                       5
<PAGE>
      The Subsidiary Guarantees shall be binding upon the Subsidiary Guarantors
and shall inure to the benefit of the Trustee and the Holders and, in the event
of any transfer or assignment of rights by any Holder or the Trustee respecting
the Security upon which the foregoing Subsidiary Guarantees are noted, the
rights and privileges herein conferred upon that party shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions hereof and in the Indenture.

      The Subsidiary Guarantees shall not be valid or obligatory for any
purposes until the certificate of authentication on the Security upon which the
foregoing Subsidiary Guarantees are noted shall have been executed by the
Trustee under the Indenture by the manual signature of one of its authorized
signatories.


                                                                    Exhibit 23.1

          (b) Promptly after receiving a Notice of Borrowing, the Administrative
Agent shall notify each Bank of the contents thereof and of such Bank's ratable
share of such Borrowing and such Notice of Borrowing shall not thereafter be
revocable by the Borrower. The Borrower shall not give a Notice of Borrowing at
any time if, after giving effect thereto, more than 12 Groups of Loans would be
outstanding.

          (c) Not later than 12:00 Noon (New York City time) on the date of each
Borrowing, each Bank shall make available its ratable share of such Borrowing,
in Federal or other funds immediately available in New York City, to the
Administrative Agent at its address specified in or pursuant to Section 10.01.
Unless the Administrative Agent determines that any applicable condition
specified in Article 3 has not been satisfied, the Administrative Agent will
make the funds so received from the Banks available to the Borrower at the
Administrative Agent's aforesaid address.

          (d) Unless the Administrative Agent shall have received notice from a
Bank before the date of any Borrowing that such Bank will not make available to
the Administrative Agent such Bank's share of such Borrowing, the Administrative
Agent may assume that such Bank has made such share available to the
Administrative Agent on the date of such Borrowing in accordance with subsection
(b) of this Section and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount.
If and to the extent that such Bank shall not have so made such share available
to the Administrative Agent, such Bank and the Borrower severally agree to repay
to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent, at (i) if such amount is repaid by the Borrower, a rate
per annum equal to the higher of the Federal Funds Rate and the interest rate
applicable thereto pursuant to Section 2.04 and (ii) if such amount is repaid by
such Bank, the Federal Funds Rate. If such Bank shall repay to the
Administrative Agent such corresponding amount, the Borrower shall not be
required to repay such amount and the amount so repaid by such Bank shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

         SECTION 2.03. MATURITY OF LOANS. Each Loan shall mature, and the
principal amount thereof shall be due and payable (together with interest
accrued thereon), on the Maturity Date.

         SECTION 2.04. INTEREST RATES. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, from the date such Loan is
made until it becomes due for each day at a rate per annum equal to the Base
Rate. Such interest shall be payable quarterly in arrears on each Quarterly
Payment Date. Any overdue principal of or interest on any Base Rate Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the sum of 2% PLUS the interest rate otherwise applicable to such Base
Rate Loan for such day.

          (b) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such
day PLUS the London Interbank Offered Rate applicable to such Interest Period.
Such interest shall be payable for each Interest Period on the last day thereof
and, if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

         "EURO-DOLLAR MARGIN" means for any day the amount set forth below
opposite the pricing level that applies on such day:

         The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the arithmetic mean (rounded upwards, if necessary, to the next higher
1/16 of 1%) of the offered rates for deposits in Dollars quoted as of 11:00 A.M.
(London time) two Euro-Dollar Business Days before the first day of such
Interest Period on Telerate Page 3750 in an amount approximately equal to the
principal amount of the Euro-Dollar Loans to which such Interest Period is to
apply and for the approximate duration of such Interest Period; PROVIDED that if
there are more than six of such rates quoted then the highest and lowest rates
shall be eliminated for these purposes; and PROVIDED FURTHER that if no, or only
one, such offered quotation appears, the relevant arithmetic mean (calculated as
mentioned above) shall be determined (i) on the basis of the offered rates for
deposits in Dollars on the Reuters Screen LIBO Page and (ii) if such rate or
rates do not appear on either Telerate Page 3750 or the Reuters Screen LIBO
Page, on the basis of the respective rates per annum at which deposits in
Dollars are offered to each of the Reference Banks in the London interbank
market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days
before the first day of such Interest Period in an amount approximately equal to
the principal amount of the Euro- Dollar Loan of such Reference Bank to which
such Interest Period is to apply and for a period of time comparable to such
Interest Period.

          (c) Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the higher of (i) the sum of 2% PLUS the Euro-Dollar Margin for such
day PLUS the London Interbank Offered Rate applicable to such Loan on the day
before such payment was due and (ii) the sum of 2% PLUS the Euro-Dollar Margin
for such day PLUS a rate per annum equal to the quotient obtained (rounded
upward, if necessary, to the next higher 1/100 of 1%) by DIVIDING (x) the
average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the
respective rates per annum at which one day (or, if such amount due remains
unpaid more than three Euro-Dollar Business Days, then for such other period of
time not longer than three months as the Administrative Agent may select)
deposits in dollars in an amount approximately equal to such overdue payment due
to each of the Reference Banks are offered to such Reference Bank in the London
interbank market for the applicable period determined as provided above by (y)
1.00 MINUS the Euro-Dollar Reserve Percentage (or, if the circumstances
described in clause (a) or (b) of Section 8.01 shall exist, at a rate per annum
equal to the sum of 2% PLUS the Base Rate for such day).

                                       26
<PAGE>
          (d) The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder. The Administrative Agent shall promptly
notify the Borrower and the participating Banks of each rate of interest so
determined, and its determination thereof shall be conclusive in the absence of
manifest error.

          (e) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Administrative Agent as contemplated by this Section. If any
Reference Bank does not furnish a timely quotation, the Administrative Agent
shall determine the relevant interest rate on the basis of the quotation or
quotations furnished by the remaining Reference Bank or Banks or, if none of
such quotations is available on a timely basis for the reasons set forth in
clause (a) or (b) of Section 8.01, the provisions of Section 8.01 shall apply.

         SECTION 2.05. METHOD OF ELECTING INTEREST RATES. (a) The Loans included
in each Borrowing shall bear interest initially at the type of rate specified by
the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may
from time to time elect to change or continue the type of interest rate borne by
each Group of Loans (subject to subsection (d) of this Section and the
provisions of Article 8), as follows:

          (i) if such Loans are Base Rate Loans, the Borrower may elect to
         convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business
         Day and

         (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to
         convert such Loans to Base Rate Loans as of any Domestic Business Day
         or elect to continue such Loans as Euro-Dollar Loans for an additional
         Interest Period, subject to Section 2.11 if any such conversion is
         effective on any day other than the last day of an Interest Period
         applicable to such Loans.

Each such election shall be made by delivering a notice (a "NOTICE OF INTEREST
RATE ELECTION") to the Administrative Agent not later than 11:00 A.M. (New York
City time) on the third Euro-Dollar Business Day before the conversion or
continuation selected in such notice is to be effective. A Notice of Interest
Rate Election may, if it so specifies, apply to only a portion of the aggregate
principal amount of the relevant Group of Loans; PROVIDED that (A) such portion
is allocated ratably among the Loans comprising such Group, (B) the portion to
which such Notice applies, and the remaining portion to which it does not apply,
are each at least $1,000,000 (unless such portion is comprised of Base Rate
Loans) and (C) immediately after giving effect to such Notice, there shall be
not more than 12 Groups of Loans outstanding. If no such notice is timely
received before the end of an Interest Period for any Group of Euro-Dollar
Loans, the Borrower shall be

                                       27
<PAGE>
deemed to have elected that such Group of Loans be converted to Base Rate Loans
at the end of such Interest Period.

          (b)   Each Notice of Interest Rate Election shall specify:

           (i)  the Group of Loans (or portion thereof) to which such notice
         applies;

          (ii) the date on which the conversion or continuation selected in such
         notice is to be effective, which shall comply with the applicable
         clause of subsection (a) above;

         (iii) if the Loans comprising such Group are to be converted, the new
         type of Loans and, if the Loans resulting from such conversion are to
         be Euro-Dollar Loans, the duration of the next succeeding Interest
         Period applicable thereto; and

          (iv) if such Loans are to be continued as Euro-Dollar Loans for an
         additional Interest Period, the duration of such additional Interest
         Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

          (c) Promptly after receiving a Notice of Interest Rate Election from
the Borrower pursuant to subsection (a) above, the Administrative Agent shall
notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower.

          (d) The Borrower shall not be entitled to elect to convert any Loans
to, or continue any Loans for an additional Interest Period as, Euro-Dollar
Loans if (i) the aggregate principal amount of any Group of Euro-Dollar Loans
created or continued as a result of such election would be less than
$1,000,000.00 or (ii) a Default shall have occurred and be continuing when the
Borrower delivers notice of such election to the Administrative Agent.

          (e) If any Loan is converted to a different type of Loan, the Borrower
shall pay, on the date of such conversion, the interest accrued to such date on
the principal amount being converted.

         SECTION 2.06.  FEES.  (a) The Borrower shall pay to the Administrative
Agent, for the account of the Banks ratably in proportion to their respective
Commitment Percentages, a commitment fee at the Commitment Fee Rate on the
daily average amount by which the aggregate amount of the Borrowing Base

                                       28
<PAGE>
exceeds the Total Outstanding Amount.  Such commitment fee shall accrue from
and including the Effective Date to but excluding the date on which the
Commitments terminate in their entirety.

          (b) The Borrower shall pay to the Administrative Agent, for the
account of the Banks ratably in proportion to their Commitment Percentages, a
letter of credit fee calculated for each day at the Letter of Credit Fee Rate
for such day on the aggregate amount available for drawing under all Letters of
Credit at the close of business on such day.

          (c) The Borrower shall pay to each LC Issuing Bank fronting fees and
other charges in the amounts and at the times agreed between the Borrower and
such LC Issuing Bank.

          (d) Fees accrued for the account of the Banks under subsections (a)
and (b) of this Section shall be payable quarterly in arrears on each Quarterly
Payment Date and on the day on which the Commitments terminate in their entirety
and, in the case of clause (b), on the first date thereafter on which there is
no Aggregate LC Exposure.

          (e) The Borrower shall pay to the Administrative Agent such other fees
in amounts, and at the time and in the manner, previously agreed upon between
the Borrower and the Administrative Agent in the letter dated March 11, 1997
from Morgan Guaranty Trust Company of New York and J.P. Morgan Securities, Inc.
and agreed to by Bellwether Exploration Company.

         SECTION 2.07. TERMINATION OR REDUCTION OF COMMITMENTS. (a) VOLUNTARY
REDUCTION. The Borrower may, upon at least three Domestic Business Days' notice
to the Administrative Agent, (i) terminate the Commitments at any time, if there
are no Outstanding Amounts at such time, or (ii) ratably reduce from time to
time by an aggregate amount of $5,000,000 or a larger multiple of $1,000,000,
the aggregate amount of the Commitments on such date in excess of the Total
Outstanding Amount. Promptly after receiving a notice pursuant to this
subsection, the Administrative Agent shall notify each Bank of the contents
thereof.

          (b) MANDATORY SCHEDULED REDUCTION. The aggregate amount of the
Commitments shall be reduced (x) on December 31, 1998, by the aggregate amount
by which the Commitments on such date are greater than the Borrowing Base in
effect on such date and (y) on each Quarterly Date thereafter until the Maturity
Date, by an aggregate amount equal to the product of 1/12 TIMES the aggregate
amount of the Commitments on December 31, 1998 after giving effect to the
reduction on such date pursuant to clause (x) above.

                                       29
<PAGE>
          (c) APPLICATION OF REDUCTIONS. Each reduction of Commitments under
this Section 2.07 shall be applied to reduce the Commitments of the Banks pro
rata in accordance with the respective amounts thereof.

         (d) TERMINATION. Unless previously terminated, the Commitments shall
terminate in their entirety on the Maturity Date.

         SECTION 2.08. OPTIONAL PREPAYMENTS. (a) Subject in the case of Euro-
Dollar Loans to Section 2.11, the Borrower may, upon at least one Domestic
Business Day's notice to the Administrative Agent, prepay any Group of Base Rate
Loans or, upon at least three Euro-Dollar Business Days' notice to the
Administrative Agent, prepay any Group of Euro-Dollar Loans, in each case in
whole at any time, or from time to time in part in amounts aggregating
$1,000,000 or any larger multiple of $500,000, by paying the principal amount to
be prepaid together with interest accrued thereon to the date of prepayment.
Each such optional prepayment shall be applied to prepay ratably the Loans of
the several Banks included in such Group of Loans.

          (b) Promptly after receiving a notice of prepayment pursuant to this
Section, the Administrative Agent shall notify each Bank of the contents thereof
and of such Bank's ratable share of such prepayment, and such notice shall not
thereafter be revocable by the Borrower.

         SECTION 2.09. MANDATORY PREPAYMENTS. (a) Upon the date of any reduction
of Commitments pursuant to Section 2.07, the Borrower shall prepay an amount of
Loans and provide cash cover for outstanding Letters of Credit in accordance
with Section 6.03 in such amounts as may be necessary so that immediately after
giving effect to such payment and/or collateralization, (i) the Total
Outstanding Amount LESS the amount of collateral so deposited with respect to
Aggregate LC Exposure is not greater than (ii) the aggregate amount of the
Commitments as so reduced.

          (b) Without limitation of clause (a) above, if at any time the
Administrative Agent shall determine that a Borrowing Base Excession exists, the
Administrative Agent shall forthwith notify the Banks and the Borrower. On or
before the date falling 6 months after the inception of a Borrowing Base
Excession, the Borrower shall remedy such Borrowing Base Excession by (i)
prepaying such principal amount of the Loans as may be necessary to reduce the
outstanding principal amount thereof to the Borrowing Base at the date of
prepayment, (ii) providing cash cover for Aggregate LC Exposure in accordance
with Section 6.03, (iii) increasing the Borrowing Base through the addition of
Borrowing Base Properties in accordance with Sections 2.15, 5.02 and 5.21;

                                       30
<PAGE>
PROVIDED that, the value of any such Borrowing Base Properties and whether such
value is sufficient to remedy such Borrowing Base Excession shall be determined
by the Required Banks, in their good faith discretion and in a manner that is
consistent with the standards set forth in Section 2.15(c), or (iv) a
combination of (i), (ii) and/or (iii).

          (c) Each repayment or prepayment of Loans pursuant to this Section
2.09 shall be made together with accrued interest to the date of payment, and
shall be applied ratably to payment of the Loans of the several Banks in
proportion to their Commitments (or, if the Commitments have been terminated, to
the aggregate outstanding principal amounts of their Loans). Within the
foregoing limits of this Section 2.09, each required payment or prepayment shall
be made with respect to such outstanding Group or Groups of Loans as the
Borrower may designate to the Administrative Agent not less than three
Euro-Dollar Business Days prior to the date required for such payment or
prepayment or, failing such designation by the Borrower, as the Administrative
Agent may specify by notice to the Borrower and the Banks.

         SECTION 2.10. GENERAL PROVISIONS AS TO PAYMENTS. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans and LC
Reimbursement Obligations and each payment of fees hereunder (other than fees
payable directly to the LC Issuing Banks) not later than 1:00 P.M. (New York
City time) on the date when due, in Federal or other funds immediately available
in New York City, to the Administrative Agent at its address specified in or
pursuant to Section 10.01. The Administrative Agent will promptly distribute to
each Bank its ratable share of each such payment received by the Administrative
Agent for the account of the Banks. Whenever any payment of principal of, or
interest on, the Base Rate Loans or LC Reimbursement Obligations or any payment
of fees shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day.
Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Euro-Dollar
Business Day. If the date for any payment of principal is extended by operation
of law or otherwise, interest thereon shall be payable for such extended time.

          (b) Unless the Borrower notifies the Administrative Agent before the
date on which any payment is due to the Banks hereunder that the Borrower will
not make such payment in full, the Administrative Agent may assume that the
Borrower has made such payment in full to the Administrative Agent on such date
and the Administrative Agent may, in reliance on such assumption, cause to be

                                       31
<PAGE>
distributed to each Bank on such due date an amount equal to the amount then due
such Bank. If and to the extent that the Borrower shall not have so made such
payment, each Bank shall repay to the Administrative Agent forthwith on demand
such amount distributed to such Bank together with interest thereon, for each
day from the date such amount is distributed to such Bank until the date such
Bank repays such amount to the Administrative Agent, at the Federal Funds Rate.

         SECTION 2.11. FUNDING LOSSES. If the Borrower makes any payment of
principal with respect to any Euro-Dollar Loan or any Euro-Dollar Loan is
converted to a Base Rate Loan (whether such payment or conversion is pursuant to
Article 2, 6 or 8 or otherwise) on any day other than the last day of an
Interest Period applicable thereto, or the last day of an applicable period
fixed pursuant to Section 2.05(b), or if the Borrower fails to borrow, prepay,
convert or continue any Euro-Dollar Loans after notice has been given to any
Bank in accordance with Section 2.02(b), 2.05(c) or 2.08(b), the Borrower shall
reimburse each Bank within 15 days after demand for any resulting loss or
expense incurred by it (or by an existing or prospective Participant in the
related Loan), including (without limitation) any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after such payment or conversion or failure to borrow,
prepay, convert or continue; PROVIDED that such Bank shall promptly have
delivered to the Borrower a certificate as to the amount of such loss or
expense, which certificate shall be conclusive in the absence of manifest error.

         SECTION 2.12. COMPUTATION OF INTEREST AND FEES. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.13.  NOTES.  (a) The Borrower's obligation to repay the Loans
of each Bank shall be evidenced by a single Note payable to the order of such
Bank for the account of its Applicable Lending Office.

          (b) Each Bank may, by notice to the Borrower and the Administrative
Agent, request that the Borrower's obligation to repay such Bank's Loans of a
particular type be evidenced by a separate Note. Each such Note shall be in
substantially the form of Exhibit A hereto with appropriate modifications to
reflect the fact that it relates solely to Loans of the relevant type. Each
reference in this Agreement to the "Note" of such Bank shall be deemed to refer
to and include any or all of such Notes, as the context may require.

                                       32
<PAGE>
          (c) Promptly after it receives each Bank's Note pursuant to Section
3.01(a), the Administrative Agent shall forward such Note to such Bank. Each
Bank shall record the date, amount and type of each Loan made by it and the date
and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Note, endorse on the schedule forming a part thereof
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding; PROVIDED that a Bank's failure to make (or any error
in making) any such recordation or endorsement shall not affect the Borrower's
obligations hereunder or under the Notes. Each Bank is hereby irrevocably
authorized by the Borrower so to endorse its Note and to attach to and make a
part of its Note a continuation of any such schedule as and when required.

         SECTION 2.14. REGULATION D COMPENSATION. Each Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the
Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such
Bank at a rate per annum determined by such Bank up to but not exceeding the
excess of (i) (A) the applicable London Interbank Offered Rate divided by (B)
one MINUS the Euro-Dollar Reserve Percentage over (ii) the applicable London
Interbank Offered Rate. Any Bank wishing to require payment of such additional
interest (x) shall so notify the Borrower and the Administrative Agent, in which
case such additional interest on the Euro-Dollar Loans of such Bank shall be
payable to such Bank at the place indicated in such notice with respect to each
Interest Period commencing at least three Euro-Dollar Business Days after such
Bank gives such notice and (y) shall notify the Borrower at least five
Euro-Dollar Business Days before each date on which interest is payable on the
Euro-Dollar Loans of the amount then due it under this Section.

         SECTION 2.15.  BORROWING BASE.  (a) INITIAL BORROWING BASE. During the
period from the Closing Date until the next Determination Date, the Borrowing
Base shall be $90,000,000.

          (b) BORROWING BASE REDETERMINATIONS PURSUANT TO SECTION 5.02. Within
30 days after the receipt of (i) any reports delivered pursuant to Section 5.02,
together with (ii) the Borrowing Base Certificate, the Administrative Agent
shall notify the Borrower and the Banks of a proposed Borrowing Base (such date,
the "BB PROPOSAL DATE"). Within 30 days after the BB Proposal Date, if any Bank
disapproves of the proposed Borrowing Base, such Bank shall submit to the
Administrative Agent in writing, its disapproval of the proposed Borrowing Base
which disapproval shall state the maximum Borrowing Base acceptable to such
Bank. The Borrowing Base proposed by the Administrative Agent shall become the
new Borrowing Base after the close of business on the thirtieth day following
the BB Proposal Date (or the next succeeding Domestic Business Day if such date

                                       33
<PAGE>
is not a Domestic Business Day) unless, on or prior to such time, (i) the
Administrative Agent shall have received the written consent of the Required
Banks to such proposed Borrowing Base, in which case the Administrative Agent
shall notify the Borrower of the determination of the Borrowing Base by the
Banks or (ii) Banks having more than 33 1/3% of the Credit Exposure at such time
shall have expressed their disapproval to the Administrative Agent in the manner
set forth in the previous sentence, in which case, until the next Determination
Date, the Borrowing Base shall be the lowest determination agreed to by the
Required Banks and the Administrative Agent shall notify the Borrower of such
determination.

          (c) BORROWING BASE REDETERMINATION STANDARDS. Each redetermination of
the Borrowing Base pursuant to this Section 2.15 and Section 5.21 below shall be
made in good faith by all of the Banks and the Administrative Agent, in the
exercise of their reasonable discretion and in accordance with their respective
customary and prudent standards for oil and gas lending and credit transactions
as they exist at such time; PROVIDED that each of the Borrower, the Banks and
the Administrative Agent agree that the Banks will only give loan value to any
Property that is subject to a Lien or Production Payments and Reserve Sales if,
and to the extent that, the value of such Property exceeds the value of such
Lien or such Production Payments and Reserve Sales.

          (d) BORROWING BASE ELECTION. Within five Domestic Business Days after
receipt of a Borrowing Base Notice from the Administrative Agent, the Borrower
shall by notice to the Administrative Agent either accept such amount as the new
Borrowing Base or reduce the Borrowing Base from the amount proposed by the
Administrative Agent to any lesser amount. Failure by the Borrower to take
either such action within such five Domestic Business Day period shall be deemed
acceptance of such amount. Upon any such acceptance or deemed acceptance by the
Borrower, a new Borrowing Base in the amount accepted shall take effect on such
date (herein called a "DETERMINATION DATE") and shall remain in effect until but
not including the next Determination Date. Upon any such reduction by the
Borrower, a new Borrowing Base in the reduced amount specified by the Borrower
shall take effect on such date (herein also called a "DETERMINATION DATE") and
shall remain in effect until but not including the next Determination Date.

          (e)   OTHER BORROWING BASE REDETERMINATIONS.  The Borrowing Base shall
also be adjusted as provided in Section 5.21.

         SECTION 2.16. LETTERS OF CREDIT. (a) ISSUANCE. Each LC Issuing Bank
agrees, on the terms and conditions set forth in this Agreement, to issue
standby or financial (but not trade or documentary) letters of credit hereunder,
with a

minimum stated amount for each such letter of credit of $1,000,000, at the
request of the Borrower from time to time prior to the date that is 30 days
before the Maturity Date; PROVIDED that, immediately after each such Letter of
Credit is issued and participations therein are sold to the Banks as provided in
this subsection:

          (i)   the Aggregate LC Exposure shall not exceed $15,000,000;

         (ii)   in the case of each Bank, its Outstanding Amount shall not
         exceed its Commitment; and

        (iii) the Total Outstanding Amount shall not exceed the amount of the
         Borrowing Base at such time.

Whenever an LC Issuing Bank issues a Letter of Credit hereunder, such LC Issuing
Bank shall be deemed, without further action by any party hereto, to have sold
to each Bank, and each Bank shall be deemed, without further action by any party
hereto, to have purchased from such LC Issuing Bank, a participation in such
Letter of Credit, on the terms specified in this Section, equal to such Bank's
Commitment Percentage thereof

          (b) NOTICE OF PROPOSED ISSUANCE. With respect to each Letter of
Credit, the Borrower shall give the relevant LC Issuing Bank and the
Administrative Agent at least three Domestic Business Days' (or such shorter
time as the LC Issuing Bank may agree in a particular instance) prior notice (i)
specifying the date such Letter of Credit is to be issued and (ii) describing
the proposed terms of such Letter of Credit and the nature of the transactions
to be supported thereby. Promptly after it receives such notice, the
Administrative Agent shall notify each Bank of the contents thereof.

          (c) CONDITIONS TO ISSUANCE. No LC Issuing Bank shall issue any Letter
of Credit under this Section unless:

          (i) such proposed Letter of Credit is a standby or financial letter of
         credit, and not a documentary or trade letter of credit, and shall have
         a stated amount not less than $1,000,000,

         (ii)   such proposed Letter of Credit is otherwise satisfactory in
         form and substance to such LC Issuing Bank,

        (iii) the Borrower shall have executed and delivered such other
         instruments and agreements relating to such proposed Letter of Credit
         as such LC Issuing Bank shall have reasonably requested,

                                       35
<PAGE>
         (iv) such LC Issuing Bank shall have confirmed with the Administrative
         Agent on the date of such issuance that the limitations specified in
         subsection (a) of this Section will not be exceeded immediately after
         such proposed Letter of Credit is issued, and

          (v) such LC Issuing Bank shall not have been notified in writing by
         the Borrower or the Administrative Agent expressly to the effect that
         any condition specified in Section 3.02(c) or Section 3.02(d) is not
         satisfied at the time such proposed Letter of Credit is to be issued.

          (d) NOTICE OF ACTUAL ISSUANCE. Promptly after it issues any Letter of
Credit, the relevant LC Issuing Bank shall notify the Administrative Agent of
the date, face amount, beneficiary or beneficiaries and expiry date of such
Letter of Credit. Promptly after it receives such notice, the Administrative
Agent shall notify each Bank of the contents thereof and the amount of such
Bank's participation in such Letter of Credit. Promptly after it issues any
Letter of Credit, the relevant LC Issuing Bank shall send a copy of such Letter
of Credit to the Administrative Agent.

          (e) EXPIRY DATES. No Letter of Credit shall have an expiry date later
than the fifth Domestic Business Day before the Maturity Date. Subject to the
preceding sentence, each Letter of Credit issued hereunder shall expire on or
before the first anniversary of the date of such issuance; PROVIDED that,
subject to the first sentence of this clause (e), the expiry date of any Letter
of Credit may be extended from time to time at the Borrower's request, so long
as such extension is for a period not exceeding one year and is granted (or the
last day on which notice can be given to prevent such extension occurs) no
earlier than three months before the then existing expiry date thereof.

          (f) NOTICE OF PROPOSED EXTENSIONS OF EXPIRY DATES. The relevant LC
Issuing Bank shall give the Administrative Agent at least three Domestic
Business Days' notice before such LC Issuing Bank extends (or allows an
automatic extension of) the expiry date of any Letter of Credit issued by it.
Such notice shall identify such Letter of Credit, the date on which it is to be
extended (or the last day on which notice can be given to prevent such
extension) and the date to which it is to be extended. Promptly after it
receives such notice, the Administrative Agent shall notify each Bank of the
contents thereof. No LC Issuing Bank shall extend (or allow the extension of)
the expiry date of any Letter of Credit if:

          (i)   such extension does not comply with subsection (e) of this
         Section, or

                                       36
<PAGE>
         (ii) such LC Issuing Bank shall have been notified by the Borrower or
         the Administrative Agent expressly to the effect that any condition
         specified in Section 3.02(c) or Section 3.02(d) is not satisfied at the
         time of such proposed extension.

If any Letter of Credit is not extended after notice of a proposed extension
thereof has been given to the Banks, the relevant LC Issuing Bank shall promptly
notify the Administrative Agent of such failure to extend. Promptly after it
receives such notice, the Administrative Agent shall notify each Bank thereof.

          (g) DRAWINGS. If an LC Issuing Bank receives a demand for payment
under any Letter of Credit issued by it and determines that such demand should
be honored, such LC Issuing Bank shall (i) promptly notify the Borrower and the
Administrative Agent as to the amount to be paid by such LC Issuing Bank as a
result of such demand and the date of such payment (an "LC PAYMENT DATE") and
(ii) make such payment in accordance with the terms of such Letter of Credit.
Upon such notice by such LC Issuing Bank, the Administrative Agent shall
promptly notify each of the Banks as to the amount to be paid by such LC Issuing
Bank as a result of such demand and the date of such payment.

          (h)   REIMBURSEMENT BY THE BORROWER.

          (i) If any amount is drawn under any Letter of Credit, the Borrower
         irrevocably and unconditionally agrees to reimburse the relevant LC
         Issuing Bank for such amount, together with any and all reasonable
         charges and expenses which such LC Issuing Bank may pay or incur
         relative to such drawing. Such reimbursement shall be due and payable
         on the relevant LC Payment Date or the date on which such LC Issuing
         Bank notifies the Borrower of such drawing, whichever is later;
         PROVIDED that, if such notice is given after 12:00 noon (New York City
         time) on the later of such dates, such reimbursement shall be due and
         payable on the next following Domestic Business Day (the date on which
         it is due and payable being an "LC REIMBURSEMENT DUE DATE").

         (ii) In addition, the Borrower agrees to pay, on the applicable LC
         Reimbursement Due Date, interest on each amount drawn under a Letter of
         Credit, for each day from and including the date such amount is drawn
         to but excluding such LC Reimbursement Due Date, at the Base Rate for
         such day. The Borrower also agrees to pay, on demand, interest on any
         overdue amount (including any overdue interest) payable under this
         subsection (h), for each day from and including the day such amount
         becomes due to but excluding the day such amount is paid in full, at a
         rate per annum equal to the sum of 2% PLUS the Base Rate for such day.

                                       37
<PAGE>
        (iii) Each payment by the Borrower pursuant to this subsection (h) shall
         be made to the relevant LC Issuing Bank in Federal or other funds
         immediately available to it at its address specified in or pursuant to
         Section 10.01.

         (iv) Unless it gives not less than one Domestic Business Day's notice
         to the Administrative Agent to the contrary, the Borrower shall be
         deemed to have timely given a Notice of Borrowing for a Base Rate Loan
         on the date of any drawing under a Letter of Credit in the exact amount
         due the LC Issuing Bank hereunder on such date, and the Administrative
         Agent shall apply the proceeds of such Base Rate Loan to make payment
         thereof.

         (i)      PAYMENTS BY BANKS.

          (i) If the Borrower fails to pay any LC Reimbursement Obligation in
         full when due, the relevant LC Issuing Bank may notify the
         Administrative Agent of the unreimbursed amount and request that the
         Banks reimburse such LC Issuing Bank for their respective Commitment
         Percentages thereof. Promptly after it receives any such notice, the
         Administrative Agent shall notify each Bank of the unreimbursed amount
         and such Bank's Commitment Percentage thereof. Upon receiving such
         notice from the Administrative Agent, each Bank shall make available to
         such LC Issuing Bank, at its address specified in or pursuant to
         Section 10.01, an amount equal to such Bank's Commitment Percentage of
         such unreimbursed amount, in Federal or other funds immediately
         available to such LC Issuing Bank, by 3:00 P.M. (New York City time)
         (A) on the day such Bank receives such notice if it is received at or
         before 12:00 Noon (New York City time) on such day or (B) on the next
         Domestic Business Day if such notice is received after 12:00 Noon (New
         York City time) on the date of receipt, in each case together with
         interest on such amount for each day from and including the relevant LC
         Payment Date to but excluding the day such payment is due from such
         Bank at the Federal Funds Rate for such day. Upon payment in full
         thereof, such Bank shall be subrogated to the rights of such LC Issuing
         Bank against the Borrower to the extent of such Bank's Commitment
         Percentage of the related LC Reimbursement Obligation (including
         interest accrued thereon).

         (ii) If any Bank fails to pay when due any amount to be paid by it
         pursuant to clause (i) of this subsection, interest shall accrue on
         such Bank's obligation to make such payment, for each day from and
         including the date such payment became due to but excluding the date
         such Bank

                                       38
<PAGE>
         makes such payment, at a rate per annum equal to (x) for each day from
         the day such payment is due to the third succeeding Domestic Business
         Day, inclusive, the Federal Funds Rate for such day and (y) for each
         day thereafter the sum of 2% PLUS the Base Rate for such day.

        (iii) If the Borrower shall reimburse any LC Issuing Bank for any
         drawing with respect to which any Bank shall have made funds available
         to such LC Issuing Bank in accordance with clause (i) of this
         subsection, such LC Issuing Bank shall promptly upon receipt of such
         reimbursement distribute to such Bank its Commitment Percentage
         thereof, including interest, to the extent received by such LC Issuing
         Bank.

          (j) EXCULPATORY PROVISIONS. The obligations of the Borrower and the
Banks under this Section shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
which the Borrower or any Bank may have or have had against any LC Issuing Bank,
any Bank, any beneficiary of any Letter of Credit or any other Person. The
Borrower assumes all risks of the acts or omissions of any beneficiary of any
Letter of Credit with respect to the use of such Letter of Credit by such
beneficiary. None of the LC Issuing Banks, the Banks and their respective
officers, directors, employees and agents shall be responsible for, and the
obligations of each Bank to make payments to each LC Issuing Bank and of the
Borrower to reimburse each LC Issuing Bank for drawings pursuant to this Section
shall not be excused or affected by, among other things, (i) the use which may
be made of any Letter of Credit or any acts or omissions of any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents presented under any Letter of Credit or of any
endorsements thereon, even if such documents should in fact prove to be in any
or all respects invalid, insufficient, fraudulent or forged; (iii) payment by
any LC Issuing Bank against presentation of documents to it which do not comply
with the terms of the relevant Letter of Credit or (iv) any dispute between or
among the Borrower, any beneficiary of any Letter of Credit or any other Person
or any claims or defenses whatsoever of the Borrower or any other Person against
any beneficiary of any Letter of Credit. No LC Issuing Bank shall be liable for
any error, omission, interruption or delay in transmission, dispatch or delivery
of any message or advice, however transmitted, in connection with any Letter of
Credit. Any action taken or omitted by any LC Issuing Bank in connection with
any Letter of Credit and the related drafts and documents shall be binding upon
the Borrower and shall not place any LC Issuing Bank or any Bank under any
liability to the Borrower. Notwithstanding the foregoing, the provisions of this
subsection (j) shall not relieve any LC Issuing Bank from responsibility for its
own gross negligence or willful misconduct.

                                       39

          (k) INDEMNIFICATION BY BORROWER. The Borrower agrees to indemnify and
hold harmless each Bank, each LC Issuing Bank and the Administrative Agent
(collectively, the "LC INDEMNITEES") from and against any and all claims and
damages, losses, liabilities, costs or expenses (including, without limitation,
the reasonable fees and disbursements of counsel) which such LC Indemnitee may
reasonably incur (or which may be claimed against such LC Indemnitee by any
Person whatsoever) by reason of or in connection with any execution and delivery
or transfer of or payment or failure to pay under any Letter of Credit or any
actual or proposed use of any Letter of Credit; PROVIDED that the Borrower shall
not be required to indemnify any LC Indemnitee for any such claims, damages,
losses, liabilities, costs or expenses to the extent, but only to the extent,
caused by (i) its own willful misconduct or gross negligence or (ii) its failure
to pay under any Letter of Credit issued by it after the presentation to it of a
request strictly complying with the terms and conditions of such Letter of
Credit. Nothing in this subsection is intended to limit the obligations of the
Borrower under any other provision of this Section.

          (l) INDEMNIFICATION BY BANKS. The Banks shall, ratably in proportion
to their Commitment Percentages, indemnify each LC Issuing Bank (to the extent
not reimbursed by the Borrower) against any claims, damages, losses,
liabilities, reasonable costs and reasonable expenses (including, without
limitation, reasonable fees and disbursements of counsel) that any such
Indemnitee may suffer or incur in connection with this Section or any action
taken or omitted by such indemnitee under this Section; PROVIDED that the Banks
shall not be required to indemnify any LC Issuing Bank for any such claims,
damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by (i) its own gross negligence or willful misconduct, (ii) its
failure to pay under any Letter of Credit issued by it after the presentation to
it of a request strictly complying with the terms and conditions of such Letter
of Credit, (iii) its failure to comply with subsection (e) of this Section, (iv)
its liabilities under any Letter of Credit issued by it in contravention of
clause (iii) (to the extent that the limitations referred to therein were in
fact exceeded) or clause (iv) of subsection (c) of this Section or (v) its
liabilities under any Letter of Credit extended (or allowed to be automatically
extended) by it in contravention of clause (ii) of subsection (f) of this
Section.

          (m) LIABILITY FOR DAMAGES. Nothing in this Section shall preclude the
Borrower or any Bank from asserting against any LC Issuing Bank any claim for
damages suffered by the Borrower or such Bank to the extent, but only to the
extent, caused by (i) the willful misconduct or gross negligence of such LC
Issuing Bank or (ii) such LC Issuing Bank's failure to pay under any Letter of
Credit issued by it after the presentation to it of a request strictly complying
with the terms and conditions thereof.

                                       40

         (n) DUAL CAPACITIES. In its capacity as a Bank, each LC Issuing Bank
shall have the same rights and obligations under this Section as any other Bank.

          (o) INFORMATION TO BE PROVIDED TO ADMINISTRATIVE AGENT. Each LC
Issuing Bank shall furnish to the Administrative Agent upon request such
information as the Administrative Agent shall reasonably request in order to
calculate (i) the Aggregate LC Exposure existing from time to time and (ii) the
amount of any fee payable for the account of the Banks under Section 2.06(b).

representations relate solely to an earlier date and were true and correct in
all
material respects on such earlier date).

                                    ARTICLE 4

only, that:

         SECTION 4.01. CORPORATE EXISTENCE AND POWER. The Borrower is a
corporation duly incorporated, validly existing and in good standing under the
laws of the jurisdiction of its incorporation, and has all corporate powers and
all governmental licenses, consents, authorizations and approvals required to
carry on its business as now conducted (other than such governmental licenses,
consents, authorizations and approvals the failure of which to obtain would not
reasonably be expected to have a Material Adverse Effect).

                                       43
<PAGE>
         SECTION 4.02. CORPORATE AND GOVERNMENTAL AUTHORIZATION; NO
CONTRAVENTION. The execution, delivery and performance by the Borrower of the
Financing Documents are within the Borrower'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 Borrower's certificate of incorporation or by-laws or of
any agreement or other instrument evidencing Debt for borrowed money or of any
other material agreement, judgment, injunction, order, decree or other material
instrument binding upon the Borrower or any Subsidiary or result in the creation
or imposition of any Lien on any asset of the Borrower or any Subsidiary.

         SECTION 4.03. BINDING EFFECT. This Agreement constitutes a valid and
binding agreement of the Borrower and each Note, when executed and delivered in
accordance with this Agreement, will constitute a valid and binding obligation
of the Borrower, in each case enforceable in accordance with its terms, subject
to applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally and general principles of equity.

         SECTION 4.04. FINANCIAL INFORMATION. (a) The consolidated balance sheet
of the Borrower and its Consolidated Subsidiaries as of June 30, 1996 and the
related consolidated statements of income, cash flows and changes in
stockholders' equity for the Fiscal Year then ended, reported on by Deloitte &
Touche LLP and set forth in the Borrower's 1996 Form 10-K, a copy of which has
been delivered to each of the Banks, fairly present, in conformity with GAAP,
the consolidated financial position of the Borrower and its Consolidated
Subsidiaries as of such date and their consolidated results of operations and
cash flows for such Fiscal Year.

          (b) The unaudited consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as of December 31, 1996 and the related unaudited
consolidated statements of income, cash flows and changes in stockholders'
equity for the six months then ended, set forth in the Borrower's Latest Form
10-Q, a copy of which has been delivered to each of the Banks, fairly present,
on a basis consistent with the financial statements referred to in subsection
(a) of this Section, the consolidated financial position of the Borrower and its
Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such six-month period (subject to normal year-end
adjustments).

          (c) Since June 30, 1996, there has been no material adverse change in
the business, financial position or results of operations of the Borrower, its
Consolidated Subsidiaries, and the Torch Acquired Properties, considered as a
whole.

<PAGE>
         SECTION 4.05. LITIGATION. Except as disclosed on Schedule 4.05, there
is no action, suit or proceeding pending against, or to the Borrower's knowledge
threatened against or affecting, the Borrower or any Subsidiary 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 have a Material
Adverse Effect.

         SECTION 4.06. COMPLIANCE WITH ERISA. Each member of the ERISA Group has
fulfilled its obligations in all material respects 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
for an amount which, if not granted, would have subjected the ERISA Group (or
any member thereof) to a liability in excess of $5,000,000, (ii) failed to make
any contribution or payment of a material amount to any Plan or Multiemployer
Plan, or made any amendment to any Plan, which has resulted or could result in

         SECTION 5.21. EXTRAORDINARY BORROWING BASE REDETERMINATIONS. (a) TITLE
INFORMATION.

          (i) If applicable, as soon as practicable after the provision of any
         Reserve Report to the Banks pursuant to Section 5.02, the Borrower will
         deliver acquisition summaries, title opinions and due diligence reports
         (if any), in respect of any new Borrowing Base Properties being added
         to the Borrowing Base for any period, prepared in connection with the
         acquisition and the financing of the acquisition of such Property
         prepared for the Borrower or the Person financing such acquisition and
         such additional title information in form and substance reasonably
         acceptable to the Administrative Agent as is requested so that the
         Administrative Agent shall have received, together with the title
         information previously received by it, satisfactory title information
         covering Oil and Gas Property representing 80% of the value of the new
         Borrowing Base Properties as set forth in such Reserve Report, as such
         value is set forth therein.

         (ii) The Borrower shall commence to cure any material title defects or
         exceptions, which are not Liens permitted by Section 5.10, raised by
         any title information, within 90 days after a reasonable request by the
         Administrative Agent to cure such material defects or exceptions.

        (iii) If the Borrower is unable to cure any material title defects
         reasonably requested by the Administrative Agent to be cured within
         such 90-day period or the Borrower does not comply with the
         requirements to provide acceptable title information covering 80% of
         the value of such new Borrowing Base Properties evaluated in the most
         recent Reserve Report,

                                       61
<PAGE>
         such default shall not be a Default, but instead the Required Banks
         shall have the right to exercise the following remedy in their sole
         discretion from time to time, and any failure to so exercise this
         remedy at any time is not a waiver as to future exercise of the remedy
         by the Banks. To the extent that the Banks are not satisfied with a
         title to any Property after the time period in Section 5.21(a)(ii) has
         elapsed, the Administrative Agent shall, if so requested by the
         Required Banks, send a Borrowing Base Notice to the Company that the
         then outstanding Borrowing Base shall be reduced by an amount equal to
         the loan value attributed to such unacceptable Property by the Banks in
         the latest Borrowing Base. This new Borrowing Base shall become
         effective upon receipt of such notice.

          (b) BORROWING BASE PROPERTY SALES. Whenever the Borrower or any of its
Subsidiaries, in one or more transactions after the Determination Date
immediately preceding the time in question (or, prior to the first Determination
Date, after the date hereof) sells, transfers or otherwise disposes of Borrowing
Base Properties of $5,000,000 or more in the aggregate, the Borrower will
promptly give notice of such event to the Administrative Agent and each Bank
and, upon receipt of such notice, the Administrative Agent may, with the consent
of the Required Banks, either (i) request a Reserve Report as contemplated in
Section 5.02(b) and the Required Banks may make the determinations, contemplated
in Section 2.15(b), or (ii) request any supplemental information which the
Required Banks reasonably desire from the Borrower without requiring all such
reports and other information, and then designate a new Borrowing Base as the
Required Banks deem appropriate in light of such event and such supplemental
information. The determination of any new Borrowing Base pursuant to this
Section 5.21(b) shall take effect as provided in Section 2.15(d).

          (c) SUBORDINATED DEBT SALES; APPROVAL OF SUBORDINATED DEBT. Not less
than 30 days prior to any proposed issuance and sale by the Borrower of any
subordinated debt securities of the Borrower, the Borrower will deliver to the
Banks notice of such proposed transaction containing (A) the type and amount of
the subordinated debt securities to be sold, (B) the principal amount of the
subordinated debt securities that the Borrower expects to issue and sell in such
proposed transaction and (C) the material terms and conditions of the proposed
subordinated debt securities. Within 15 days after the receipt of such notice,
the Administrative Agent will notify the Banks (1) whether it approves of the
terms and conditions of the proposed subordinated debt securities and (2) of a
proposed new Borrowing Base (such notice, the "SECTION 5.21(C) NOTICE"). Within
15 days after the provision of the Section 5.21(c) Notice, if any Bank
disapproves of (i) the terms and conditions of the proposed subordinated debt
securities, and/or (ii) the proposed new Borrowing Base, such Bank shall submit
to the Administrative Agent in writing such disapproval, which disapproval
shall, as applicable, state (A)

                                       62
<PAGE>
the reasons and basis for its disapproval of the terms and conditions of the
proposed subordinated debt securities and/or (B) the maximum Borrowing Base
acceptable to such Bank (taking into account the effect of the issuance of such
proposed subordinated debt securities). On the close of business on the
fifteenth day after the provisions of the Section 5.21(c) Notice (or the next
succeeding Domestic Business Day if such day is not a Domestic Business Day),
(i) the terms and conditions of the proposed subordinated debt securities shall
be deemed to have been approved by the Required Banks (and the Administrative
Agent shall notify the Borrower of such approval) unless, on or prior to such
fifteenth day (or such next succeeding Domestic Business Day, as applicable),
Banks having more than 331/3 of the Credit Exposure at such time shall have
expressed their disapproval of such terms and conditions in the manner set forth
in the previous sentence, in which case the Borrower will not issue any
subordinated debt securities until it repeats the foregoing procedures of this
Section 5.21(c) and (ii) such proposed Borrowing Base shall become the basis for
determining the new Borrowing Base, pursuant to the final sentence of this
Section 5.21(c), unless on or prior to such fifteenth day, (A) the
Administrative Agent shall have received the written consent of the Required
Banks to such proposed Borrowing Base, or (B) Banks having more than 331/3 of
the Credit Exposure at such time shall have expressed their disapproval to the
Administrative Agent in the manner set forth in the previous sentence, in which
case the Administrative Agent shall notify the Borrower of the lowest
determination agreed to by the Required Banks. Upon the consummation of the sale
of any subordinated debt securities, (i) the Borrower shall notify the
Administrative Agent of the principal amount of the subordinated debt securities
sold in such transaction and (ii) the Borrowing Base will on and as of such date
be redetermined in an amount equal to (A) the maximum Borrowing Base agreed to
by the Required Banks PLUS (B) the difference of (1) the principal amount of the
subordinated debt securities sold in such transaction MINUS (2) the principal
amount that the Borrower had expected to issue in the proposed subordinated debt
securities sale, as specified in its notice to the Banks pursuant to the first
sentence of this Section 5.21(c).

or any Person acting on such holder's behalf to accelerate the maturity thereof;

          (g) the Borrower or any Material Subsidiary shall commence a voluntary
case or other proceeding seeking liquidation, reorganization or other relief
with respect to itself or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any

adjudicating that any Material Plan must be terminated; or there shall 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 Multiemployer Plans which

         SECTION 6.02. NOTICE OF DEFAULT. The Administrative Agent shall give
notice to the Borrower under Section 6.01(c) promptly upon being requested to do
so by any Bank and shall thereupon notify all the Banks thereof.

         SECTION 6.03. CASH COVER. The Borrower agrees that, if an Event of
Default shall have occurred and be continuing and Banks having more than 662/3%
of the Aggregate LC Exposure instruct the Administrative Agent to request cash
collateral pursuant to this Section, the Borrower will, promptly after it
receives such request from the Administrative Agent, pay to the Administrative
Agent an amount in immediately available funds equal to the then aggregate
amount available for subsequent drawings under all outstanding Letters of
Credit, to be held by the Administrative Agent, under arrangements satisfactory
to it, to secure the payment of all LC Reimbursement Obligations arising from
subsequent drawings under such Letters of Credit (which collateral shall be
released by the Administrative Agent to the Borrower upon the cure of any such
Event of Default); PROVIDED that, if any Event of Default specified in Section
6.01(g) or 6.01(h) occurs with respect to the Borrower, the Borrower shall pay
such amount

                                       66

to the Administrative Agent forthwith without any notice or demand or any other
act by the Administrative Agent or the Banks.

                                    ARTICLE 7

                            THE ADMINISTRATIVE AGENT

         SECTION 7.01. APPOINTMENT AND AUTHORIZATION. Each Bank irrevocably
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement as are delegated to
the Administrative Agent by the terms hereof or thereof, together with all such
powers as are reasonably incidental thereto.

         SECTION 7.02. ADMINISTRATIVE AGENTS AND AFFILIATES. Morgan Guaranty
Trust Company of New York shall have the same rights and powers under this
Agreement as any other Bank and may exercise or refrain from exercising the same
as though it were not the Administrative Agent, and Morgan Guaranty Trust
Company of New York and its affiliates may accept deposits from, lend money to
and generally engage in any kind of business with the Borrower or any Subsidiary
or affiliate of the Borrower as if it were not the Administrative Agent.

         SECTION 7.03. ACTION BY ADMINISTRATIVE AGENT. The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default, except as
expressly provided in Article 6.

         SECTION 7.04. CONSULTATION WITH EXPERTS. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

         SECTION 7.05. LIABILITY OF ADMINISTRATIVE AGENT. None of the
Administrative Agent or any of its affiliates or any of their respective
directors, officers, agents or employees shall be liable for any action taken or
not taken by it in connection herewith (i) with the consent or at the request of
the Required Banks (or such different number of Banks as any provision hereof
expressly requires for such consent or request) or (ii) in the absence of its
own gross negligence or willful misconduct. Neither the Administrative Agent nor
any of its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty

                                       67
<PAGE>
or representation made in connection with this Agreement or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of the Borrower; (iii) the satisfaction of any condition specified in
Article 3, except receipt of items required to be delivered to the
Administrative Agent; or (iv) the validity, effectiveness or genuineness of this
Agreement, the Notes or any other instrument or writing furnished in connection
herewith. The Administrative Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement or other writing
(which may be a bank wire, telex, facsimile or similar writing) believed by it
to be genuine or to be signed by the proper party or parties. Without limiting
the generality of the foregoing, the use of the term "agent" in this Agreement
with reference to the Administrative Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom and is intended to create or reflect only an administrative
relationship between independent contracting parties.

         SECTION 7.06. INDEMNIFICATION. The Banks shall, ratably in proportion
to their Credit Exposures, indemnify the Administrative Agent, its affiliates
and their respective directors, officers, agents and employees (to the extent
not reimbursed by the Borrower) against any cost, expense (including counsel
fees and disbursements), claim, demand, action, loss or liability (except such
as result from such indemnitees' gross negligence or willful misconduct) that
such indemnitees may suffer or incur in connection with this Agreement or any
action taken or omitted by such indemnitees hereunder.

         SECTION 7.07. CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance on the Administrative Agent or any other
Bank, 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
Bank also acknowledges that it will, independently and without reliance on the
Administrative Agent or any other Bank, 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 this Agreement.

         SECTION 7.08. SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent
may resign at any time by giving notice thereof to the Banks and the Borrower.
Upon any such resignation, the Required Banks shall have the right to appoint a
successor Administrative Agent with the consent of the Borrower (which shall not
be unreasonably withheld). If no successor Administrative Agent shall have been
so appointed by the Required Banks, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent gives notice of
resignation, then the retiring Administrative Agent may, on behalf of the Banks,
appoint a successor Administrative Agent, which shall be a commercial bank

                                       68
<PAGE>
organized or licensed under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $100,000,000. Upon
the acceptance of its appointment as Administrative Agent hereunder by a
successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. After any retiring
Administrative Agent resigns as Administrative Agent hereunder, the provisions
of this Article 7 shall inure to its benefit as to actions taken or omitted to
be taken by it while it was Administrative Agent.

         SECTION 7.09. ADMINISTRATIVE AGENT'S FEE. The Borrower shall pay to the
Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon by the Borrower and the Administrative Agent.

                                    ARTICLE 8

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.01. BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
If on or before the first day of any Interest Period for any Euro-Dollar Loan:

          (a) the Administrative Agent is advised by the Reference Banks that
deposits in dollars (in the applicable amounts) are not being offered to the
Reference Banks in the London interbank market for such Interest Period, or

          (b) Banks holding 50% or more of the aggregate principal amount of the
affected Loans advise the Administrative Agent that the London Interbank Offered
Rate as determined by the Administrative Agent will not adequately and fairly
reflect the cost to such Banks of funding their Euro-Dollar Loans for such
Interest Period,

the Administrative Agent shall forthwith give notice thereof to the Borrower and
the Banks, whereupon until the Administrative Agent notifies the Borrower that
the circumstances giving rise to such suspension no longer exist, (i) the
obligations of the Banks to make Euro-Dollar Loans or to continue or convert
outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each
outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the
last day of the then current Interest Period applicable thereto. Unless the
Borrower notifies the Administrative Agent at least two Domestic Business Days
before the date of any affected Borrowing for which a Notice of Borrowing has
previously been given

                                       69
<PAGE>
that it elects not to borrow on such date, such Borrowing shall instead be made
as a Base Rate Borrowing.

         SECTION 8.02. ILLEGALITY. If, on or after the date hereof, the adoption
of any applicable law, rule or regulation, or any change in any applicable law,
rule or regulation, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Bank (or
its Euro-Dollar Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency, shall make it unlawful or impossible for any Bank (or its Euro-Dollar
Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Bank
shall so notify the Administrative Agent, the Administrative Agent shall
forthwith give notice thereof to the other Banks and the Borrower, whereupon
until such Bank notifies the Borrower and the Administrative Agent that the
circumstances giving rise to such suspension no longer exist, the obligation of
such Bank to make Euro-Dollar Loans, or to convert outstanding Loans into
Euro-Dollar Loans or continue outstanding Loans as Euro-Dollar Loans, shall be
suspended. Before giving any notice to the Administrative Agent pursuant to this
Section, such Bank shall designate a different Euro-Dollar Lending Office if
such designation will avoid the need for giving such notice and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank. If such notice
is given, each Euro-Dollar Loan of such Bank then outstanding shall be converted
to a Base Rate Loan either (a) on the last day of the then current Interest
Period applicable to such Euro- Dollar Loan if such Bank may lawfully continue
to maintain and fund such Loan as a Euro-Dollar Loan to such day or (b)
immediately if such Bank shall determine that it may not lawfully continue to
maintain and fund such Loan as a Euro-Dollar Loan to such day.

         SECTION 8.03. INCREASED COST AND REDUCED RETURN. (a) If on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) or any LC
Issuing Bank with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency, shall impose,
modify or deem applicable any reserve (including, without limitation, any such
requirement imposed by the Board of Governors of the Federal Reserve System, but
excluding any such requirement with respect to which such Bank is entitled to
compensation during the relevant Interest Period under Section 2.13), special
deposit, insurance assessment or similar requirement against assets of, deposits
with or for the account of, or credit (including letters of credit and
participations therein) extended by, any Bank (or its

                                       70
<PAGE>
Applicable Lending Office) or any LC Issuing Bank or shall impose on any Bank
(or its Applicable Lending Office) or any LC Issuing Bank or the London
interbank market any other condition affecting its Euro-Dollar Loans, its Notes
or its obligation to make Euro-Dollar Loans or its obligations hereunder in
respect of Letters of Credit and the result of any of the foregoing is to
increase the cost to such Bank (or its Applicable Lending Office) or such LC
Issuing Bank of making or maintaining any Euro-Dollar Loan or issuing or
participating in any Letter of Credit, or to reduce the amount of any sum
received or receivable by such Bank (or its Applicable Lending Office) or such
LC Issuing Bank under this Agreement or under its Note with respect thereto, by
an amount deemed by such Bank or LC Issuing Bank to be material, then, within 15
days after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall pay to such Bank or LC Issuing Bank such additional amount or
amounts as will compensate such Bank or LC Issuing Bank for such increased cost
or reduction.

          (b) If any Bank shall have determined that, after the date hereof, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change in any such law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on capital
of such Bank (or its Parent) as a consequence of such Bank's obligations
hereunder to a level below that which such Bank (or its Parent) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank (with a copy to the Administrative Agent), the Borrower shall pay
to such Bank such additional amount or amounts as will compensate such Bank (or
its Parent) for such reduction.

          (c) Each Bank and LC Issuing Bank will promptly notify the Borrower
and the Administrative Agent of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Bank or LC Issuing Bank to
compensation pursuant to this Section and will designate a different Applicable
Lending Office if such designation will avoid the need for, or reduce the amount
of, such compensation and will not, in the judgment of such Bank or LC Issuing
Bank, be otherwise disadvantageous to it. A certificate of any Bank or LC
Issuing Bank claiming compensation under this Section and setting forth the
additional amount or amounts to be paid to it hereunder shall be conclusive in
the absence of manifest error. In determining such amount, such Bank or LC
Issuing Bank may use any reasonable averaging and attribution methods.

                                       71
<PAGE>
         SECTION 8.04. TAXES. (a) For the purposes of this Section, the
following terms have the following meanings:

         "TAXES" means any and all present or future taxes, duties, levies,
imposts, deductions, charges or withholdings of any nature with respect to any
payment by the Borrower or any Guarantor, as the case may be, pursuant to this
Agreement or under any Note, and all liabilities with respect thereto, EXCLUDING
(i) in the case of each Bank Party, income taxes, franchise taxes and other
similar taxes imposed on or measured by its net income (or, in lieu of net
income, total assets, net worth or shareholders' capital), by a jurisdiction
under the laws of which it is organized or in which its principal executive
office is located or, in the case of each Bank, in which its Applicable Lending
Office is located and (ii) in the case of each Bank, any United States
withholding tax imposed on such payment, but not excluding any portion of such
tax that exceeds the United States withholding tax which would have been imposed
on such a payment to such Bank under the laws and treaties in effect when such
Bank first becomes a party to this Agreement.

         "OTHER TAXES" means any present or future stamp or documentary taxes
and any other excise or property taxes, or similar charges or levies, which
arise from any payment made pursuant to this Agreement or under any Note or from
the execution, delivery, registration or enforcement of, or otherwise with
respect to, this Agreement or any Note.

          (b) All payments by the Borrower or any Guarantor to or for the
account of any Bank Party hereunder or under any Note shall be made without
deduction for any Taxes or Other Taxes; PROVIDED that, if the Borrower or any
Guarantor shall be required by law to deduct any Taxes or Other Taxes from any
such payment, (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section) such Bank Party receives an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrower
or any Guarantor, as the case may be, shall make such deductions, (iii) the
Borrower or such Guarantor, as the case may be, shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable law and (iv) the Borrower shall promptly furnish to the
Administrative Agent, at its address specified in or pursuant to Section 10.01,
the original or a certified copy of a receipt evidencing payment thereof.

          (c) The Borrower agrees to indemnify each Bank Party for the full
amount of Taxes and Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section), whether or not correctly or legally imposed, paid by such Bank
Party and

                                       72
<PAGE>
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto. This indemnification shall be paid within 15 days after
such Bank Party makes demand therefor.

          (d) Each Bank Party organized under the laws of a jurisdiction outside
the United States, on or before it signs and delivers this Agreement in the case
of each Bank listed on the signature pages hereof and on or before it becomes a
Bank in the case of each other Bank, and from time to time thereafter if
requested in writing by the Borrower (but only so long as such Bank remains
lawfully able to do so), shall provide each of the Borrower and the
Administrative Agent with Internal Revenue Service form 1001 or 4224, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Bank is entitled to benefits under an income tax treaty to
which the United States is a party which exempts such Bank from United States
withholding tax or reduces the rate of withholding tax on payments of interest
for the account of such Bank or certifying that the income receivable by it
pursuant to this Agreement is effectively connected with the conduct of its
trade or business in the United States.

          (e) For any period with respect to which a Bank has failed to provide
the Borrower or the Administrative Agent with the appropriate form referred to
in Section 8.04(d) (unless such failure is due to a change in treaty, law or
regulation occurring after the date on which such form originally was required
to be provided), such Bank shall not be entitled to indemnification under
Section 8.04(b) or 8.04(c) with respect to Taxes imposed by the United States;
PROVIDED that if a Bank, that is otherwise exempt from or subject to a reduced
rate of withholding tax, becomes subject to Taxes because of its failure to
deliver a form required hereunder, the Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Taxes.

          (f) If the Borrower or any Guarantor is required to pay additional
amounts to or for the account of any Bank pursuant to this Section as a result
of a change in law or treaty occurring after such Bank first became a party to
this Agreement, then such Bank will, at the Borrower's request, change the
jurisdiction of its Applicable Lending Office if, in the sole judgment of such
Bank, such change (i) will eliminate or reduce any such additional payment which
may thereafter accrue and (ii) is not otherwise disadvantageous to such Bank.

         SECTION 8.05. BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURO-DOLLAR
LOANS. If (i) the obligation of any Bank to make, or to continue or convert
outstanding Loans as or to, Euro-Dollar Loans has been suspended pursuant to
Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or
8.04 with respect to its Euro-Dollar Loans, and in any such case the Borrower
shall, by at least five Euro-Dollar Business Days' prior notice to such Bank

                                       73
<PAGE>
through the Administrative Agent, have elected that the provisions of this
Section shall apply to such Bank, then, unless and until such Bank notifies the
Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist, all Loans which would otherwise be made by such
Bank as (or continued as or converted to) Euro-Dollar Loans shall instead be
Base Rate Loans (on which interest and principal shall be payable
contemporaneously with the related Euro-Dollar Loans of the other Banks). If
such Bank notifies the Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first
day of the next succeeding Interest Period applicable to the related Euro-Dollar
Loans of the other Banks.

         SECTION 8.06. SUBSTITUTION OF BANK; NOTICE OF COSTS OR EXPENSES. (a) If
(i) the obligation of any Bank to make, or to continue or convert Loans as or
to, Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any
Bank has demanded compensation under Section 8.03 or 8.04, the Borrower shall
have the right (a) with the assistance of the Administrative Agent, to seek a
mutually satisfactory substitute bank or banks (which may be one or more of the
Banks) to purchase the Note and assume the rights and obligations of such Bank
hereunder, or (b) to elect to terminate this Agreement as to such Bank, and in
connection therewith not to borrow or convert to any Base Rate Loan provided for
in Section 8.02 or to prepay any Base Rate Loan made pursuant to Section 8.02 or
8.05, PROVIDED that the Borrower (x) notifies such Bank through the
Administrative Agent of such election at least three Euro-Dollar Business Days
before any date fixed for such a borrowing, prepayment or conversion, as the
case may be, and (y) prepays all of such Bank's outstanding Loans at the end of
the respective Interest Periods applicable thereto or, if required by clause (b)
of the last sentence of Section 8.02, immediately. Upon receipt by the
Administrative Agent of such notice the Commitment of such Lender, if
outstanding, shall terminate.

          (b) Notwithstanding anything to the contrary contained in Section 8.02
through 8.04, the Borrower shall not be obligated to pay any costs or expenses
of any Bank arising pursuant to such sections that are attributable to the
Excluded Period with respect to such additional costs or expenses; PROVIDED,
that if an applicable law, rule, regulation, guideline or request that gives
rise to such costs or expenses shall be adopted or made on any date after the
Closing Date and shall be applicable to the period (a "RETROACTIVE PERIOD")
prior to the date on which such law, rule, regulation, guideline or request is
adopted or made, the limitation on the Borrower's obligations to pay such
additional costs or expenses under this Section 8.06(b) shall not apply to the
additional costs or expenses of any Bank payable in respect of such Retroactive
Period.

                                    GUARANTY

         SECTION 9.01. THE GUARANTY. Each Guarantor hereby unconditionally
guarantees the full and punctual payment (whether at stated maturity, upon
acceleration or otherwise) of the principal of and interest on each Note issued
by the Borrower pursuant to this Agreement, and the full and punctual payment of
all other amounts payable by the Borrower under this Agreement. Upon failure by
the Borrower to pay punctually any such amount, each Guarantor shall forthwith
on demand pay the amount not so paid at the place and in the manner specified in
this Agreement.

         SECTION 9.02. GUARANTY UNCONDITIONAL. The obligations of each Guarantor
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:

          (i) any extension, renewal, settlement, compromise, waiver or release
         in respect of any obligation of the Borrower or any other Guarantor
         under this Agreement or any Note, by operation of law or otherwise;

         (ii)   any modification or amendment of or supplement to this
         Agreement or any Note;

        (iii) any release, impairment, non-perfection or invalidity of any
         direct or indirect security for any obligation of the Borrower or any
         other Guarantor under this Agreement or any Note;

         (iv) any change in the corporate existence, structure or ownership of
         the Borrower or any other Guarantor, or any insolvency, bankruptcy,
         reorganization or other similar proceeding affecting the Borrower, any
         other Guarantor or their respective assets or any resulting release or
         discharge of any obligation of the Borrower or any other Guarantor
         contained in this Agreement or any Note;

          (v) the existence of any claim, set-off or other rights which the
         Guarantor may have at any time against the Borrower, any other
         Guarantor, the Administrative Agent, any Bank or any other Person,
         whether in connection herewith or any unrelated transactions, PROVIDED
         that nothing herein shall prevent the assertion of any such claim by
         separate suit or compulsory counterclaim;

                                       75
<PAGE>
         (vi) any invalidity or unenforceability relating to or against the
         Borrower or any other Guarantor for any reason of this Agreement or any
         Note, or any provision of applicable law or regulation purporting to
         prohibit the payment by the Borrower or any other Guarantor of the
         principal of or interest on any Note or any other amount payable by the
         Borrower or any other Guarantor under this Agreement; or

        (vii) any other act or omission to act or delay of any kind by the
         Borrower, any other Guarantor, the Administrative Agent, any Bank or
         any other Person or any other circumstance whatsoever which might, but
         for the provisions of this paragraph, constitute a legal or equitable
         discharge of the Guarantor's obligations hereunder.

         SECTION 9.03. DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN
CERTAIN CIRCUMSTANCES. Each Guarantor's obligations hereunder shall remain in
full force and effect until the Commitments shall have terminated and the
principal of and interest on the Notes and all other amounts payable by the
Borrower under this Agreement shall have been paid in full. If at any time any
payment of the principal of or interest on any Note or any other amount payable
by the Borrower under this Agreement is rescinded or must be otherwise restored
or returned upon the insolvency, bankruptcy or reorganization of the Borrower or
any other Guarantor or otherwise, each Guarantor's obligations hereunder with
respect to such payment shall be reinstated at such time as though such payment
had been due but not made at such time.

         SECTION 9.04. WAIVER BY EACH GUARANTOR. Each Guarantor irrevocably
waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be
taken by any Person against the Borrower or any other Guarantor or any other
Person.

         SECTION 9.05. SUBROGATION AND CONTRIBUTION. Upon making any payment
with respect to any Borrower hereunder, the relevant Guarantor shall be
subrogated to the rights of the payee against the Borrower with respect to such
payment; PROVIDED that no Guarantor shall enforce any payment by way of
subrogation or contribution against any other Obligor until all amounts of
principal of and interest on the Notes and all other amounts payable by the
Borrower under this Agreement have been paid in full.

         SECTION 9.06. STAY OF ACCELERATION. If acceleration of the time for
payment of any amount payable by the Borrower under this Agreement or any Note
is stayed upon insolvency, bankruptcy or reorganization of the Borrower, all
such amounts otherwise subject to acceleration under the terms of this Agreement
shall nonetheless be payable by each Guarantor hereunder forthwith on demand by

                                       76
<PAGE>
the Administrative Agent made at the request of the requisite proportion of the
Banks specified in Article 6 of the Agreement.

         SECTION 9.07. LIMIT OF LIABILITY. The obligations of each Guarantor
hereunder shall be limited to an aggregate amount equal to the largest amount
that would not render its obligations hereunder subject to avoidance under
Section 548 of the United States Bankruptcy Code or any comparable provisions of
any applicable state law.

         SECTION 9.08. RELEASE OF GUARANTOR. (a) Upon any sale by the Borrower
of a Subsidiary permitted by and in compliance with this Agreement, such
Subsidiary shall automatically and without further action by any Bank or the
Administrative Agent be released from its obligations, if any, as a Guarantor
hereunder.

          (b) If at any time a Subsidiary that is a Guarantor at such time
hereunder shall no longer qualify as a Material Subsidiary, then, PROVIDED that
a Default shall not have occurred and be continuing, upon the request of the
Borrower to the Administrative Agent and the receipt of the consent of the
Required Banks (which consent shall not be unreasonably withheld), such
Subsidiary shall be released from its obligations as a Guarantor hereunder.

                                   ARTICLE 10

                                  MISCELLANEOUS

         SECTION 10.01. NOTICES. All notices, requests and other communications

telex number set forth on the signature pages hereof, (b) in the case of any
Guarantor, in care of the Borrower (c) in the case of any Bank, at its address,
facsimile number or telex number set forth in its Administrative Questionnaire
or (d) in the case of any party, at such other address, facsimile number or
telex number as such party may hereafter specify for the purpose by notice to

communication shall be effective (i) if given by telex, when transmitted to the
telex number referred to in this Section and the appropriate answerback is
received, (ii) if given by facsimile, when transmitted to the facsimile number
referred to in this Section and confirmation of receipt is received, (iii) if

                                       77
<PAGE>
Section; PROVIDED that notices to the Administrative Agent or any LC Issuing
Bank under Article 2 or Article 8 shall not be effective until received.

         SECTION 10.02. NO WAIVERS. No failure or delay by any Bank Party
exercising any right, power or privilege hereunder or under any Note shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 10.03. EXPENSES; INDEMNIFICATION. (a) The Borrower shall pay
(i) all reasonable out-of-pocket expenses of the Administrative Agent, including
reasonable fees and disbursements of special counsel for the Administrative
Agent, in connection with the preparation and administration of this Agreement,
any waiver or consent hereunder or any amendment hereof or any Default or
alleged Default hereunder and (ii) if an Event of Default occurs, all reasonable
out-of-pocket expenses incurred by each Bank Party, including (without
duplication) the reasonable fees and disbursements of outside counsel and the
allocated cost of inside counsel, in connection with such Event of Default and
collection, bankruptcy, insolvency and other enforcement proceedings resulting
therefrom.

          (b) The Borrower agrees to indemnify each Bank Party, their respective
affiliates and the respective directors, officers, agents and employees of the
foregoing (each an "INDEMNITEE") and hold each Indemnitee harmless from and
against any and all liabilities, losses, damages, costs and expenses of any
kind, including, without limitation, the reasonable fees and disbursements of
counsel, which may be incurred by such Indemnitee in connection with any
investigative, administrative or judicial proceeding (whether or not such
Indemnitee shall be designated a party thereto) brought or threatened relating
to or arising out of this Agreement or any actual or proposed use of any Letter
of Credit or any proceeds of Loans hereunder; PROVIDED that no Indemnitee shall
have the right to be indemnified hereunder for such Indemnitee's own gross
negligence or willful misconduct as determined by a court of competent
jurisdiction.

          (c) The Borrower hereby indemnifies each Indemnitee from and against
and agrees to hold each of them harmless from any and all liabilities, losses,
damages, costs and expenses of any kind (including without limitation reasonable
expenses of investigation by engineers, environmental consultants and similar
technical personnel and reasonable fees and disbursements of counsel) of such
Indemnitee arising out of, in respect of or in connection with any and all
Environmental Liabilities. Without limiting the generality of the foregoing
(except as provided in the proviso at the end of this sentence), the Borrower
hereby waives

                                       78
<PAGE>
all rights for contribution or any other rights of recovery with respect to
liabilities, losses, damages, costs and expenses arising under or related to
Environmental Laws that it might have by statute or otherwise against each
Indemnitee; PROVIDED that no Indemnitee shall have the right to be indemnified
hereunder for such Indemnitee's own gross negligence or willful misconduct as
determined by a court of competent jurisdiction.

         SECTION 10.04. SHARING OF SET-OFFS. Each Bank agrees that if it shall,
by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount of principal and interest then due with
respect to the Loans and participations in LC Reimbursement Obligations held by
it which is greater than the proportion received by any other Bank in respect of
the aggregate amount of principal and interest then due with respect to the
Loans and participations in LC Reimbursement Obligations held by such other
Bank, the Bank receiving such proportionately greater payment shall purchase
such participations in the Loans and participations in LC Reimbursement
Obligations held by the other Banks, and such other adjustments shall be made,
as may be required so that all such payments of principal and interest with
respect to the Loans and participations in LC Reimbursement Obligations held by
the Banks shall be shared by the Banks pro rata; PROVIDED that nothing in this
Section shall impair the right of any Bank to exercise any right of set-off or
counterclaim it may have and to apply the amount subject to such exercise to the
payment of indebtedness of any Obligor other than its indebtedness in respect of
the Loans and LC Reimbursement Obligations. Each Obligor agrees, to the fullest
extent it may effectively do so under applicable law, that any holder of a
participation in a Loan or LC Reimbursement Obligation, whether or not acquired
pursuant to the foregoing arrangements, may exercise rights of set-off or
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of such Obligor in the
amount of such participation.

         SECTION 10.05. AMENDMENTS AND WAIVERS. Any provision of this Agreement
or the Notes may be amended or waived if, but only if, such amendment or waiver
is in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Administrative Agent or any LC Issuing Bank are affected
thereby, by the Administrative Agent or such LC Issuing Banks, as the case may
be); PROVIDED that no such amendment or waiver shall, unless signed by all the
Banks, (i) increase or decrease the Commitment of any Bank (except for a ratable
decrease in the Commitments of all Banks) or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or the
amount of any LC Reimbursement Obligation or any interest thereon or any fees
hereunder, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or of any LC Reimbursement Obligation or any interest
thereon or any fees hereunder or for the termination of any Commitment

                                       79
<PAGE>
or (except as expressly provided in Section 2.14) extend the expiry date of any
Letter of Credit, (iv) change the aggregate amount by which or to which the
Commitments are required to be reduced on or prior to any Commitment Reduction
Date, (v) release any Guarantor from its obligations hereunder (except pursuant
to Section 9.08) or (vi) change the percentage of the Commitments or of the
Aggregate LC Exposure or of the aggregate unpaid principal amount of the Loans,
or the number of Banks, which shall be required for the Banks or any of them to
take any action under this Section or any other provision of this Agreement.

         SECTION 10.06. SUCCESSORS; PARTICIPATIONS AND ASSIGNMENTS. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns, except that the
Borrower may not assign or otherwise transfer any of its rights under this
Agreement without the prior written consent of all the Bank Parties.

          (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "PARTICIPANT") participating interests in its Commitment or
any or all of its Loans and participations in Letters of Credit. If a Bank
grants any such participating interest to a Participant, whether or not upon
notice to the Borrower and the Administrative Agent, such Bank shall remain
responsible for the performance of its obligations hereunder, and the Borrower,
the LC Issuing Banks and the Administrative Agent shall continue to deal solely
and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement. Any agreement pursuant to which any Bank may
grant such a participating interest shall provide that such Bank shall retain
the sole right and responsibility to enforce the obligations of the Borrower and
the LC Issuing Banks hereunder including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this
Agreement; PROVIDED that such participation agreement may provide that such Bank
will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii) or (iv) of Section 10.05 without the
consent of the Participant. The Borrower agrees that each Participant shall, to
the extent provided in its participation agreement, be entitled to the benefits
of Section 2.13 and Article 8 with respect to its participating interest. An
assignment or other transfer which is not permitted by subsection (c) or (d)
below shall be given effect for purposes of this Agreement only to the extent of
a participating interest granted in accordance with this subsection.

          (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "ASSIGNEE") all, or a proportionate part of all, of its
rights and obligations under this Agreement and its Note, and such Assignee
shall assume such rights and obligations, pursuant to an Assignment and
Assumption Agreement substantially in the form of Exhibit D hereto signed by
such Assignee

                                       80
<PAGE>
and such transferor Bank, with (and subject to) the subscribed consent of the
Borrower (which shall not be unreasonably withheld; PROVIDED that the
withholding of any consent by the Borrower with respect to any assignment to an
Assignee that is not a commercial bank shall not be deemed to be unreasonable),
the Administrative Agent and the LC Issuing Banks; PROVIDED that if an Assignee
is an affiliate of such transferor Bank or was a Bank immediately before such
assignment, or, if at the time of such assignment, an Event of Default pursuant
to Section 6.01(a), (g) or (h) shall have occurred and be continuing, no such
consent of the Borrower shall be required. Each such assignment shall be in such
an amount that, after such assignment is made, each of the assignor Bank and the
Assignee will have an Outstanding Amount, together with their respective unused
Commitments, of at least $10,000,000. When such instrument has been signed and
delivered by the parties thereto and such Assignee has paid to such transferor
Bank the purchase price agreed between them, such Assignee shall be a Bank party
to this Agreement and shall have all the rights and obligations of a Bank with a
Commitment as set forth in such instrument of assumption, and the transferor
Bank shall be released from its obligations hereunder to a corresponding extent,
and no further consent or action by any party shall be required. Upon the
consummation of any assignment pursuant to this subsection, the transferor Bank,
the Administrative Agent and the Borrower shall make appropriate arrangements so
that, if required, a new Note is issued to the Assignee. In connection with any
such assignment, the transferor Bank shall pay to the Administrative Agent an
administrative fee for processing such assignment in the amount of $2,500. If
the Assignee is not incorporated under the laws of the United States or a
political subdivision thereof, it shall deliver to the Borrower and the
Administrative Agent certification as to its exemption from deduction or
withholding of, or its entitlement to a reduced withholding rate for, United
States federal income taxes in accordance with Section 8.04.

          (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank. No such assignment
shall release the transferor Bank from its obligations hereunder.

          (e) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring
such Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

         SECTION 10.07. NO RELIANCE ON MARGIN STOCK. Each of the Banks
represents to the Administrative Agent and each of the other Banks that it in
good

                                       81
<PAGE>
faith is not relying upon any "margin stock" (as defined in Regulation U) as
collateral in the extension or maintenance of the credit provided for in this
Agreement.

         SECTION 10.08. GOVERNING LAW; SUBMISSION TO JURISDICTION. This
Agreement and each Note shall be governed by and construed in accordance with
the laws of the State of New York. Each Obligor hereby submits to the
nonexclusive jurisdiction of the United States District Court for the Southern
District of New York and of any New York State court sitting in New York City
for purposes of all legal proceedings arising out of or relating to this
Agreement or the transactions contemplated hereby. Each Obligor irrevocably
waives, to the fullest extent permitted by law, any objection which it may now
or hereafter have to the laying of the venue of any such proceeding brought in
such a court and any claim that any such proceeding brought in such a court has
been brought in an inconvenient forum.

         SECTION 10.09. COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement
may be signed in any number of counterparts, each of which shall be an original,
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 Administrative Agent has received from
each of the parties hereto a counterpart hereof signed by such party or
facsimile or other written confirmation satisfactory to the Administrative Agent
confirming that such party has signed a counterpart hereof.

         SECTION 10.10. WAIVER OF JURY TRIAL. THE BORROWER AND EACH BANK PARTY
HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

         SECTION 10.11. APPOINTMENT OF AGENT FOR SERVICES OF PROCESS. (a) Each
Obligor hereby irrevocably designates, appoints, authorizes and empowers as its
agent for service of process, CT Corporation System at its offices currently
located at 1633 Broadway, New York, New York 10019 to accept and acknowledge for
and on behalf of each Obligor service of any and all process, notices or other
documents that may be served in any suit, action or proceeding relating hereto
in any New York State or Federal court sitting in The State of New York.

          (b) In lieu of service upon its agent, each Obligor consents to
process being served in any suit, action or proceeding relating hereto by
mailing a copy

                                       82
<PAGE>
thereof by registered or certified air mail, postage prepaid, return receipt
requested, to its address designated pursuant to Section 10.01. Each Obligor
agrees that such service (1) shall be deemed in every respect effective service
of process upon it in any such suit, action or proceeding and (2) shall, to the
fullest extent permitted by law, be taken and held to be valid personal service
upon and personal delivery to it.

          (c) Nothing in this Section shall affect the right of any party hereto
to serve process in any manner permitted by law, or limit any right that any
party hereto may have to bring proceedings against any other party hereto in the
courts of any jurisdiction or to enforce in any lawful manner a judgment
obtained in one jurisdiction in any other jurisdiction.

         SECTION 10.12. JUDGMENT CURRENCY. If for the purposes of enforcing the
obligations of the Borrower any hereunder it is necessary to convert a sum due
from such Person in U.S. dollars ("DOLLARS") into another currency, the parties
hereto agree, to the fullest extent that they may effectively do so, that the
rate of exchange used shall be that at which in accordance with normal banking
procedures the Administrative Agent and the Banks could purchase dollars with
such currency at or about 11:00 A.M. (New York City time) on the Domestic
Business Day preceding that on which final judgment is given. The obligations in
respect of any sum due to the Administrative Agent and the Banks hereunder
shall, notwithstanding any adjudication expressed in a currency other than
dollars, be discharged only to the extent that on the Domestic Business Day
following receipt by the Administrative Agent and the Banks of any sum adjudged
to be so due in such other currency the Administrative Agent and the Banks may
in accordance with normal banking procedures purchase dollars with such other
currency; if the amount of dollars so purchased is less than the sum originally
due to the Administrative Agent and the Banks in dollars, the Borrower and each
Guarantor agrees, to the fullest extent that it may effectively do so, as a
separate obligation and notwithstanding any such adjudication, to indemnify the
Administrative Agent and the Banks against such loss, and if the amount of
dollars so purchased exceeds the sum originally due to the Administrative Agent
and the Banks, it shall remit such excess to the Borrower.

         SECTION 10.13.  MAXIMUM INTEREST RATE.  (a) Nothing contained in this
Agreement or the Notes shall require the Borrower to pay interest at a rate
exceeding the maximum rate permitted by applicable law.

           (b) If the amount of interest payable for the account of any Bank on
any interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to this Agreement, would exceed the
maximum amount permitted by applicable law to be charged by such Bank, the
amount of interest

                                       83
<PAGE>
payable for its account on such interest payment date shall be automatically
reduced to such maximum permissible amount.

           (c) If the amount of interest payable for the account of any Bank in
respect of any interest computation period is reduced pursuant to clause (b) of
this Section and the amount of interest payable for its account in respect of
any subsequent interest computation period, computed pursuant to this Agreement,
would be less than the maximum amount permitted by applicable law to be charged
by such Bank, then the amount of interest payable for its account in respect of
such subsequent interest computation period shall be automatically increased to
such maximum permissible amount; PROVIDED that at no time shall the aggregate
amount by which interest paid for the account of any Bank has been increased
pursuant to this clause (c) exceed the aggregate amount by which interest paid
for its account has theretofore been reduced pursuant to clause (b) of this
Section.

                                       84
<PAGE>
         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

                                      NOTE

                               New York, New York

         For value received, Bellwether Exploration Company, a Delaware
corporation (the "BORROWER"), promises to pay to the order of
______________________ (the "BANK"), for the account of its Applicable Lending
Office, the unpaid principal amount of each Loan made by the Bank to the
Borrower pursuant to the Credit Agreement referred to below on the maturity date
provided for in the Credit Agreement. The Borrower promises to pay interest on
the unpaid principal amount of each such Loan on the dates and at the rate or
rates provided for in the Credit Agreement. All such payments of principal and
interest shall be made in lawful money of the United States in Federal or other
immediately available funds at the office of Morgan Guaranty Trust Company of
New York, 60 Wall Street, New York, New York.

         All Loans made by the Bank, the respective types thereof and all
repayments of the principal thereof shall be recorded by the Bank and, if the
Bank so elects in connection with any transfer or enforcement hereof,
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding may be endorsed by the Bank on the schedule attached
hereto, or on a continuation of such schedule attached to and made a part
hereof; PROVIDED that the failure of the Bank to make any such recordation or
endorsement shall not affect the Borrower's obligations hereunder or under the
Credit Agreement.

         This note is one of the Notes referred to in the Credit Agreement dated
as of April 21, 1997 among Bellwether Exploration Company, the Guarantors, the
Banks and the LC Issuing Banks party thereto and Morgan Guaranty Trust Company
of New York, as Administrative Agent (as the same may be amended from time to
time, the "CREDIT AGREEMENT"). Terms defined in the Credit Agreement are used
herein with the same meanings. Reference is made to the Credit Agreement for,
INTER ALIA, provisions for the prepayment hereof, the acceleration of the
maturity hereof and to the effect that no provision of the Credit Agreement or
this note shall require the payment or permit the charging or collection of
interest in an amount in excess of the highest amount permitted by applicable
law.

                            COUNSEL FOR THE OBLIGORS

April 21, 1997

To:      Morgan Guaranty Trust Company
         of New York, as Administrative Agent
         60 Wall Street
         New York, New York  10260

         And the Banks listed on Schedule I Attached Hereto

Ladies and Gentlemen:

         We have acted as counsel for Bellwether Exploration Company (the
"BORROWER"), Odyssey Petroleum Corporation ("ODYSSEY"), Black Hawk Oil Company
("BLACK HAWK" and together with Odyssey collectively, the "CORPORATE
GUARANTORS") and 1989-I TEAI Limited Partnership (the "LP GUARANTOR" and
together with the Corporate Guarantors, collectively, the "GUARANTORS") in
connection with the Senior Reducing Revolving Credit Agreement dated as of April
21, 1997 (the "CREDIT AGREEMENT") among the Borrower, the Guarantors Party
Thereto, the Banks Party Thereto and LC Issuing Banks Referred to Therein and
Morgan Guaranty Trust Company of New York ("MORGAN GUARANTY"), as Administrative
Agent (the "ADMINISTRATIVE AGENT"). Terms defined in the Credit Agreement are
used herein as therein defined. This opinion is being rendered to you at the
request of our clients pursuant to Section 3.01(c) of the Credit Agreement.

         In preparing this opinion letter, we have examined executed
counterparts of (i) the Credit Agreement and (ii) those certain promissory notes
(the "NOTES"), dated April 21, 1997, executed by the Borrower and payable to the
order of each of the Banks listed on Schedule I, respectively, delivered
pursuant to the Credit Agreement. In addition, we have also examined originals
or copies, certified or otherwise identified to our satisfaction, of such
documents, corporate records, certificates of public officials and other
instruments and have conducted such other

                                       B-1
<PAGE>
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         In making this examination, we have assumed, with respect to all
documents which we have examined: the genuineness of all signatures thereon, the
authenticity of all documents submitted to us as originals, the conformity to
the originals of all documents submitted to us as copies, the authenticity of
the originals of such copies, and the completeness of all such documents and
copies. As to certain questions of fact material to such opinions, we have,
where such facts were not otherwise verified or established, relied upon the
factual representations contained in the Agreement, the certificates and other
documents delivered pursuant thereto and other certifications of officers of the
Borrower and the Guarantors. For purposes of this opinion letter, we also have
assumed the due authorization, execution and delivery of, and the validity and
binding effect of, the Credit Agreement with regard to all parties thereto other
than the Borrower and the Guarantors.

         Upon the basis of the foregoing, and subject to the qualifications,
limitations and exceptions hereinafter set forth, we are of the opinion that:

           1. The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of Delaware.

           2. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes (a) are within the Borrower's corporate powers,
(b) have been duly authorized by all necessary corporate action on the part of
the Borrower, (c) require no action by or in respect of, or filing with, any
governmental body, agency or official (other than actions or filings required in
the ordinary course of business) and (d) do not contravene, or constitute a
default, or result in the creation or imposition of any Lien (other than Liens
that arise in the ordinary course of business) on any asset of the Borrower or
any Subsidiary, under, any provision (i) of applicable statutory law or
regulation or (ii) of the Borrower's certificate of incorporation or by-laws or
(iii) of any existing obligation of the Borrower under any material agreement
filed by the Borrower with the SEC or any agreement or instrument evidencing
Debt for borrowed money known to us or (iv) of any material judgment,
injunction, order, decree or other instrument binding upon the Borrower or any
Subsidiary and known to us.

           3. The Credit Agreement constitutes a valid and binding agreement of
the Borrower and the Notes issued thereunder today constitute valid and binding
obligations of the Borrower, in each case enforceable against the Borrower in
accordance with its terms, subject to (x) applicable bankruptcy, insolvency,
fraudulent transfer or conveyance, reorganization, moratorium, receivership or

<PAGE>
similar laws affecting creditors' rights generally and (y) general principles of
equity, whether considered by a court of law or equity.

           4. Each of the Borrower's corporate Subsidiaries identified on
SCHEDULE II attached hereto is a corporation validly existing and in good
standing under the laws of its jurisdiction of incorporation.

           5. Each of the Corporate Guarantors is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware. The LP Guarantor is a limited partnership duly formed and validly
existing under the laws of the State of Texas.

           6. The execution, delivery and performance by each of the Guarantors
of the Credit Agreement (a) are within such Guarantor's corporate or partnership
powers, as applicable, (b) have been duly authorized by all necessary corporate
or partnership action, as applicable, on the part of such Guarantor, (c) require
no action by or in respect of, or filing with, any governmental body, agency or
official (other than actions or filings required in the ordinary course of
business) and (d) do not contravene, or constitute a default or result in the
creation or imposition of any Lien (other than Liens that arise in the ordinary
course of business) on any asset of such Guarantor, under, any provision (i) of
applicable statutory law or regulation or (ii) of the certificate of
incorporation or by-laws or limited partnership agreement, as applicable, of
such Guarantor or (iii) of any existing obligation of such Guarantor under any
material agreement filed by the Borrower or such Guarantor with the SEC or any
agreement or instrument evidencing Debt for borrowed money known to us, or (iv)
of any material judgment, injunction, order, decree or other instrument binding
upon such Guarantor and known to us.

           7. The Credit Agreement constitutes a valid and binding agreement of
each of the Guarantors, enforceable against each Guarantor in accordance with
its terms, subject to (x) applicable bankruptcy, insolvency, fraudulent transfer
or conveyance, reorganization, moratorium, receivership or similar laws relating
to or affecting creditors' rights generally and (y) general principles of
equity, whether considered by a court of law or equity.

         We hereby confirm to you that, to the best of our knowledge, there is
no action, suit or proceeding pending or overtly threatened in writing against
the Borrower or any Subsidiary before any court or arbitrator or any
governmental body, agency or official not otherwise disclosed in the Credit
Agreement or in any certificate or document delivered pursuant thereto, which
could reasonably be expected to materially adversely affect the business,
consolidated financial position or consolidated results of operations of the
Borrower and its Consolidated

<PAGE>
Subsidiaries, considered as a whole, or which seeks to affect the validity of
the Credit Agreement or the Notes.

         The foregoing opinions are limited in all respects to the substantive
law of the State of New York, the General Corporation law of the State of
Delaware and the federal law of the United States, and we assume no
responsibility as to the applicability thereto, or the effect thereon, of the
laws of any other jurisdiction. In addition, we express no opinion as to any
applicable state securities, blue sky, tax or legal investment laws, and we
express no opinion as to the enforceability of any indemnification provisions of
documents to the extent that any such indemnification would be contrary to
public policy.

         Our opinion in paragraph 4 above, regarding the due incorporation,
valid existence and good standing of persons other than the Borrower or the
Guarantors, is based solely upon review and reliance upon certificates of public
officials.

         The qualification of any opinion or statement herein by the use of the
words "to our knowledge" or "known to us" means that during the course of
representation as described in this opinion letter, no information has come to
the attention of the attorneys in this firm involved in the transactions
described which would give such attorneys current actual knowledge of the
existence of the facts so qualified. Except as set forth herein, we have not
undertaken any investigation to determine the existence of such facts, and no
inference as to our knowledge thereof shall be drawn from the fact of our
representation of any party or otherwise.

         This opinion letter (i) has been furnished to you at your request and
may not be furnished, reproduced, distributed or disclosed to anyone without our
prior written consent, (ii) is rendered solely for your information in
connection with the referenced transaction and may not be relied upon by any
other person or for any other purpose without our prior written consent, (iii)
is rendered as of the date hereof, and we undertake no, and hereby disclaim any,
obligation to advise you of any changes or any new developments which might
affect any matters or opinions set forth herein, and (iv) is limited to the
matters expressly stated herein and no opinions may be inferred or implied
beyond the matters expressly stated herein.

                                                 Very truly yours,

c/o Morgan Guaranty Trust Company
  of New York, as Administrative Agent
60 Wall Street
New York, New York  10260

Dear Sirs:

         We have participated in the preparation of the Credit Agreement dated
as of April 21, 1997 (the "CREDIT AGREEMENT") among Bellwether Exploration
Company, a Delaware corporation (the "BORROWER"), the Guarantors, the Banks and
LC Issuing Banks party thereto and Morgan Guaranty Trust Company of New York, as
Administrative Agent, and have acted as special counsel for the Administrative
Agent for the purpose of rendering this opinion pursuant to Section 3.01(d) of
the Credit Agreement. Terms defined in the Credit Agreement are used herein as
therein defined.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments and have conducted such other
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         Upon the basis of the foregoing, we are of the opinion that:

           1. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers and
have been duly authorized by all necessary corporate action.

           32. The Credit Agreement constitutes a valid and binding agreement of
the Borrower and the Notes issued thereunder today constitute valid and binding

                                       C-1
<PAGE>
obligations of the Borrower, in each case enforceable in accordance with its
terms, subject to applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally and general principles of equity.

         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the federal laws of the
United States of America and the General Corporation Law of the State of
Delaware. In giving the foregoing opinion, we express no opinion as to the
effect (if any) of any law of any jurisdiction (except the State of New York) in
which any Bank is located which limits the rate of interest that such Bank may
charge or collect.

         This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or
relied upon by any other Person without our prior written consent.

                                                 Very truly yours,

                       ASSIGNMENT AND ASSUMPTION AGREEMENT

         AGREEMENT dated as of _________, 19__ among [NAME OF ASSIGNOR] (the

the LC Issuing Banks party thereto and MORGAN GUARANTY TRUST COMPANY OF NEW
YORK, as Administrative Agent (the "ADMINISTRATIVE AGENT") (as amended from time
to time, the "CREDIT AGREEMENT");

         WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrower and participate in Letters of Credit in

<PAGE>
         SECTION 2. ASSIGNMENT. The Assignor hereby assigns and sells to the
Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount and a corresponding portion of each of its
outstanding Loans, and the Assignee hereby accepts such assignment from the
Assignor and assumes all of the obligations of the Assignor under the Credit
