     I.   Amendments to Credit Agreement.

     Article I, DEFINITIONS, of the Credit Agreement is hereby amended by adding

     "CGI  Credit  Agreement"  has the meaning  prescribed  for such term in the
     Second Amendment.

     reference to balance  sheets,  Financial  Statements,  GAAP,  and/or within
     other  defined  terms  and  covenants   relating  to  Borrower  and/or  the
     Guarantors shall be deemed in every case to exclude any and all information
     relating to Continental Gas, Inc.

     "Second  Amendment"  means the Second  Amendment to Credit  Agreement dated
     October 22, 2003 among Bank Parties and Borrower.

     Article I,  DEFINITIONS,  of the Credit Agreement is hereby further amended
by revising the definition of "Guarantor(s)" to read as follows:

     "Guarantor(s)" means, individually and collectively,  Continental Resources

     Hundred Forty Five Million Dollars ($145,000,000.00)."

     Section 4.01, Existence,  is hereby amended by revising the final clause in

following new Section 6.20:

     terms of any material  contract with CGI, or amend in any material  respect
     any material  contract with CGI, if after giving  effect to the  amendment,
     the terms of the amended  contract would be less favorable to Borrower than
     prior to such amendment.

     Section  7.01,  Enumeration  of Events of  Default,  is hereby  amended  by
relabeling  subsections  (i) and (j) thereof to become  subsections (j) and (k),
and by inserting the following new subsection (i):

     and any such default shall remain unremedied for in excess of the period of
     grace, if any, with respect thereto."

Borrower's failure to be in compliance with the Current Ratio covenant set forth
in Section 6.15 of the Credit  Agreement  for the quarter  ended  September  30,
2003.  This  one-time  waiver is not intended to establish any course of dealing
between the Bank Parties and Borrower, or to indicate any intention or agreement
to grant future waivers of any  non-compliance by Borrower with any of the terms
of the Credit Agreement. Any future waivers must be in writing and signed by the
Bank  Parties,  and any alleged  waiver that is not in writing and signed by the

     A. The execution and delivery of this Second  Amendment and the performance
     by the Borrower of its obligations  under this Second  Amendment are within
     the Borrower's power, have been duly authorized by all necessary  corporate
     action, have received all necessary  governmental approval (if any shall be
     required),  and do not  and  will  not  contravene  or  conflict  with  any

     agreement binding upon the Borrower.

     B. The Credit Agreement as amended by this Second Amendment  represents the
     legal, valid and binding  obligations of the Borrower,  enforceable against
     the  Borrower  in  accordance  with their  respective  terms  subject as to
     enforcement only to bankruptcy, insolvency,  reorganization,  moratorium or

covenant or  agreement  except for those set forth in the Credit  Agreement,  as
hereby amended,  and in the other documents  previously  executed or executed of
even date herewith.

     IX. Governing Law. THIS SECOND AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE APPLICABLE LAWS OF THE
UNITED STATES OF AMERICA.  This Second Amendment has been entered into in Harris
County,  Texas,  and it shall be performable  for all purposes in Harris County,
Texas. Courts within the State of Texas shall have jurisdiction over any and all
disputes  between  the  Borrower  and  the  Banks,  whether  in law  or  equity,
including,  but not limited to, any and all disputes  arising out of or relating
to this Second Amendment or any other Security Instrument; and venue in any such
dispute whether in federal or state court shall be laid in Harris County, Texas.

     X. Severability.  Whenever possible each provision of this Second Amendment
shall  be  interpreted  in  such  manner  as to be  effective  and  valid  under
applicable  law,  but if  any  provision  of  this  Second  Amendment  shall  be
prohibited  by  or  invalid  under  applicable  law,  such  provision  shall  be
ineffective  to  the  extent  of  such   prohibition   or  invalidity,   without
invalidating the remainder of such provision or the remaining provisions of this
Second Amendment.

     XI. Execution in Counterparts. This Second Amendment may be executed in any
number of counterparts  and by the different  parties on separate  counterparts,
and each  such  counterpart  shall be  deemed  to be an  original,  but all such
counterparts shall together constitute but one and the same agreement.

for convenience of reference only, and shall not affect the construction of this
Second Amendment.

     XIII.  Successors and Assigns.  This Second Amendment shall be binding upon

contemplated hereby.

AGREEMENTS  OF THE  PARTIES.  THERE ARE NO WRITTEN ORAL  AGREEMENTS  BETWEEN THE
PARTIES.
