Section 2.04.  Interest.  The unpaid principal amount of the
Advances shall bear interest prior to maturity at a varying rate
per annum equal from day to day to the lesser of (a) the Maximum
Rate or (b) the Prime Rate in effect from day to day, and each
change in the rate of interest charged on the Advances shall become
effective, without notice to Borrower, on the effective date of
each change in the Prime Rate or the Maximum Rate, as the case may
be; provided, however, if at any time the rate of interest
specified in clause (b) preceding shall exceed the Maximum Rate,
thereby causing the interest on the Advances to be limited to the
Maximum Rate, then any subsequent reduction in the Prime Rate shall
not reduce the rate of interest on the Advances below the Maximum
Rate until the total amount of interest actually accrued on the
Advances equals the aggregate amount of interest which would have
accrued on the Advances if the interest rate specified in clause
(b) preceding had at all times been in effect.  Accrued and unpaid
interest on the Advances shall be payable on the first day of each
month commencing on August 1, 1995, and on the earlier of the
Termination Date or any other date on which the principal amount of
the Advances is paid (whether as a result of optional or mandatory
prepayment or acceleration).  All past due principal and interest
shall bear interest at the Default Rate.

Section 2.05.  Requests for Advances.  Each Advance shall be made
upon receipt by Lender of notice requesting such Advance from
Borrower.  Such request may be made by telephone.  Each such
request shall constitute a representation by Borrower that the sum
of the amount of the outstanding Advances plus the amount of the
requested Advance does not exceed the lesser of the Commitment or
the Borrowing Base, and at any time Lender may request written
evidence from Borrower to such effect.

Section 2.06.  Use of Proceeds.  The proceeds of Advances shall be
used for general working capital purposes.

Section 2.07.  Mandatory Prepayment.  If at any time the
outstanding principal amount of the Advances exceeds the Borrowing
Base, Borrower shall promptly prepay the outstanding Advances by
the amount of the excess plus accrued and unpaid interest on the
amount so prepaid.

Section 2.08.  Commitment Fee; Reduction or Termination of
Commitment.  Borrower agrees to pay to Lender a commitment fee on
the average daily unused portion of the Commitment, from and
including the Closing Date to and including the Termination Date,
at the rate of one quarter of one percent (1/4%) per annum based on
a 360 day year and the actual number of days elapsed, payable on 


                                9
                               12


the first day of each January 1, April 1, July 1 and October 1,
commencing on October 1, 1995, and on the Termination Date. 
Borrower shall have the right at any time to terminate in whole or
from time to time to irrevocably reduce in part the Commitment upon
at least three (3) Business Days prior notice to Lender specifying
the effective date thereof, whether a termination or reduction is
being made, and the amount of any partial reduction. 
Simultaneously with giving such notice, Borrower shall prepay the
amount by which the unpaid principal amount of the Advances exceeds
the Commitment (after giving effect to such notice) plus accrued
and unpaid interest on the principal amount so prepaid.  The
Commitment may not be reinstated after it has been terminated or
reduced.

interest, and other amounts to be made by Borrower under this
Agreement, the Note or any other Loan Documents shall be made to
Lender at its office at 1000 Louisiana, Houston, Texas 77002,

funds.  Whenever any payment under this Agreement, the Note or any
other Loan Document shall be stated to be due on a day that is not
a Business Day, such payment shall be due on the next Business Day,
and interest shall continue to accrue during such extension.

Section 3.02.  Voluntary Prepayment.  Borrower may prepay the Note
in whole at any time or from time to time in part without premium
or penalty but with accrued interest to the date of prepayment on
the amount so prepaid.

Section 3.03.  Computation of Interest.  Interest on the
indebtedness evidenced by the Note shall be computed on the basis
of a year of 360 days and the actual number of days elapsed
(including the first day but excluding the last day) unless such
calculation would result in a usurious rate, in which case interest
shall be calculated on the basis of a year of 365 or 366 days, as
the case may be.

Section 11.08.  Maximum Interest Rate.  No provision of this

unequal parts the total amount of interest throughout the entire
contemplated term of the indebtedness evidenced by the Note so that
interest for the entire term does not exceed the Maximum Rate.
