           In  consideration  of  the  mutual covenants  and  agreements  herein
contained, the parties hereto hereby agree as follows, amending and restating in
its  entirety the Credit Agreement dated as of December 23, 1994, by and between

                                    ARTICLE I
                         DEFINITIONS AND INTERPRETATION

1.1   Terms Defined Above.  As used in this Agreement, the terms "Agent,"  "Bank
One,"   "BOM,"  "Borrower,"  "Compass,"  "DNB,"  "Existing  Credit   Agreement,"
"Lender," and "Lenders" shall have the meaning assigned to them hereinabove.

1.2  Additional Defined Terms.  As used in this Agreement, each of the following
terms  shall  have  the  meaning assigned thereto in this  Section,  unless  the
context otherwise requires:

           "Accounts"  shall  mean all accounts receivable, book  debts,  notes,
drafts, instruments, documents, acceptances, and other forms of obligations  now
owned  or hereafter received or acquired by or belonging or owing to any  Person
(including,  without  limitation, under any trade names,  styles,  or  divisions
thereof),  whether arising from the sale or lease of goods or the  rendition  of
services  or  any  other transaction (including, without  limitation,  any  such
obligation which might be characterized as an account, general intangible, other
than  contract rights under contracts containing prohibitions against assignment
of  or  the granting of a security interest in the rights of a party thereunder,
or   chattel  paper  under  the  Uniform  Commercial  Code  in  effect  in   any
jurisdiction),  and  all rights of such Person in, to, and  under  all  purchase
orders  now owned or hereafter received or acquired by it for goods or services,
and  all rights of such Person to any goods the sale or lease of which gave rise
to  any of the foregoing (including, without limitation, returned or repossessed
goods and rights of unpaid sellers), and all moneys due or to become due to such
Person under all contracts for the sale or lease of goods or the performance  of
services (whether or not earned by performance) or in connection with any  other
transaction,   now  in  existence  or  hereafter  arising,  including,   without
limitation,  all  collateral security and guarantees of any kind  given  by  any
Person with respect to any of the foregoing.

           "Additional  Costs" shall mean costs which the Agent  or  any  Lender
determines  are  attributable  to  its obligation  to  make  or  its  making  or
maintaining any LIBO Rate Loan or issuing or participating in Letters of Credit,
or  any reduction in any amount receivable by the Agent or any Lender in respect
of any such obligation or any LIBO Rate Loan or Letter of Credit, resulting from
any  Regulatory  Change which (a) changes the basis of taxation of  any  amounts
payable  to the Agent or such Lender under this Agreement or any Note in respect
of  any  LIBO  Rate Loan or Letter of Credit (other than taxes  imposed  on  the
overall net income of the Agent or such Lender or its Applicable Lending  Office
for  any  such  LIBO Rate Loan by the jurisdiction in which the  Agent  or  such
Lender  has  its principal office or Applicable Lending Office), (b) imposes  or
modifies  any  reserve,  special deposit, minimum  capital,  capital  ratio,  or
similar  requirements  (other  than  the Reserve  Requirement  utilized  in  the
determination  of  the  Adjusted  LIBO Rate  for  such  Loan)  relating  to  any
extensions  of  credit  or  other  assets of, or  any  deposits  with  or  other
liabilities of, the Agent or such Lender (including LIBO Rate Loans  and  Dollar
deposits in the London interbank market in connection with LIBO Rate Loans),  or
the  Commitment of the Agent or such Lender, or the London interbank market,  or
(c)  imposes any other condition affecting this Agreement or any Note or any  of
such extensions of credit, liabilities, or Commitments.

           "Adjusted LIBO Rate" shall mean, for any Interest Period for any LIBO

                                TERMS OF FACILITY

2.1   Term  Loan.   (a)  Upon  the  terms and  conditions  and  relying  on  the
representations  and  warranties  contained  in  this  Agreement,  each   Lender
severally agrees to make, on the Business Day designated by the Borrower in  the
initial Borrowing Request but not later than April 28, 1995, a term loan  to  or
for  the  benefit  of  the Borrower in the principal amount  of  the  Term  Loan
Commitment  Amount of such Lender.  The Commitments of the Lenders to  make  the
Loans  shall  be terminable by the Borrower by notice to the Agent at  any  time
prior to April 28, 1995; provided, however, all fees accrued pursuant to Section
2.14  shall  be paid by the Borrower and such Commitments may not thereafter  be
reinstated.

      (b)  Subject  to  the  terms  of this Agreement, at any  time  prior  to  
Final Maturity, the Borrower may convert Loans of one type or with one Interest 
Period into Loans of another type or with a different Interest Period.  Each 
conversion of Loans shall be in an amount at least equal to $500,000.  Each 
conversion of or into a Loan of a different type or, in the case of a LIBO Rate 
Loan, having a different Interest Period, shall be deemed a separate conversion 
for purposes of the  foregoing, one for each type of Loan or Interest Period.  
Anything in  this Agreement  to  the contrary notwithstanding, the aggregate 
principal amount of LIBO Rate Loans having the same Interest Period shall be at
least equal to $1,000,000; and if any LIBO Rate Loan would otherwise be in a 
lesser principal amount for any period, such Loan shall be a Floating Rate 
Loan during such period.

     (c)  Not later than 3:00 p.m., Central Standard or Daylight Savings Time, 
as the case may be, on the date specified for the borrowing under this Section,
each Lender shall make available an amount equal to its Term Loan Commitment
Amount to the Agent, at an account designated by the Agent, in immediately
available funds, for the account of the Borrower.  The amount so received by
the Agent shall, subject to the terms and conditions hereof, be made available
to the Borrower in immediately available funds at the Principal Office.  All 
Loans by each Lender shall be maintained at the Applicable Lending Office of 
such Lender and shall be evidenced by the Note of such Lender.

      (d)  The  failure  of any Lender to make the Loan required to be made by
it hereunder shall not relieve any other Lender of its obligation to make the 
Loan required to be made by it, and no Lender shall be responsible for the 
failure of any other Lender to make any Loan.

2.2   Letter of Credit Facility.  (a) Upon the terms and conditions and  relying
on the representations and warranties contained in this Agreement, the Agent, as
issuing bank for the Lenders, agrees, during the Commitment Period, to issue, on
behalf  of  the  Lenders in their respective L/C Percentage Shares,  Letters  of
Credit  for the account of the Borrower and to renew and extend such Letters  of
Credit.   Letters of Credit shall be issued, renewed, or extended from  time  to
time  on  any Business Day designated by the Borrower following the  receipt  in
accordance with the terms hereof by the Agent of the written (or oral, confirmed
promptly  in writing) request by a Responsible Officer of the Borrower  therefor
and  a Letter of Credit Application.  Letters of Credit shall be issued in  such
amounts  as the Borrower may request; provided, however, that (i) no  Letter  of
Credit  shall  have  an expiration date which is more than 180  days  after  the
issuance  thereof  or more than 60 days after the Commitment  Termination  Date,
(ii) each automatically renewable Letter of Credit shall provide that it may  be
terminated  by  the Agent at its then current expiry date by not  less  than  30
days'  written notice by the Agent to the beneficiary of such Letter of  Credit,
and  (iii)  the  L/C  Exposure shall not exceed at any time the  lesser  of  the
Maximum L/C Commitment Amount or the Borrowing Base.

      (b)  Prior to any Letter of Credit Payment in respect of any Letter of 
Credit, each Lender shall be deemed to be a participant through the Agent with
respect to the relevant Letter of Credit (including, without limitation, the 
Existing Letters of Credit) in the obligation of the Agent, as the issuer of 
such Letter of Credit, in an amount equal to the L/C Percentage Share of such 
Lender of the maximum amount which is or at any time may become available to 
be drawn thereunder.  Upon delivery by such Lender of funds requested pursuant 
to Section 2.2(c), such Lender shall be treated as having purchased a 
participating interest in an amount equal to such funds delivered by such Lender
to the Agent in the obligation of the Borrower to reimburse the Agent, as the 
issuer of such Letter of Credit, for any amounts payable, paid, or incurred 
by the Agent, as the issuer of such Letter of Credit, with respect to such 
Letter of Credit.

     (c)  Each Lender shall be unconditionally and irrevocably liable, without 
regard to the occurrence of any Default or Event of Default, to the extent of 
the L/C Percentage Share of such Lender at the time of issuance (or, with 
respect to the Existing Letters of Credit, on the Closing Date) of each Letter 
of Credit, to reimburse, on demand, the Agent, as the issuer of such Letter of 
Credit, for the amount of each Letter of Credit Payment under such Letter of 
Credit.  Each Letter of Credit Payment shall be deemed to be a Floating Rate 
Loan by each Lender to the extent of funds delivered by such Lender to the Agent
with respect to such Letter of Credit Payment and shall to such extent be deemed
a Floating Rate Loan under and shall be evidenced by the Note of such Lender and
shall be payable by the Borrower upon demand by the Agent.

      (d)  EACH LENDER AGREES TO INDEMNIFY THE AGENT, AS THE ISSUER OF EACH 
LETTER OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-
IN-FACT AND AFFILIATES OF THE AGENT (TO THE EXTENT NOT REIMBURSED BY THE 
BORROWER AND WITHOUT LIMITiNG THE OBLIGATION OF THE BORROWER TO DO SO), RATABLY 
ACCORDING TO THE  L/C PERCENTAGE SHARE OF SUCH LENDER AT THE TIME OF ISSUANCE OF
SUCH LETTER OF CREDIT, FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS,

EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME 
(INCLUDING, WITHOUT LIMITATION, ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE 
OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON, 
INCURRED BY OR ASSERTED AGAINST THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT
OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR 
AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR SUCH 
LETTER OF CREDIT OR ANY ACTION TAKEN OR OMITTED BY THE AGENT AS THE ISSUER OF 
SUCH LETTER OF CREDIT  OR ANY  OF  ITS  OFFICERS,  DIRECTORS,  EMPLOYEES, 
AGENTS,  ATTORNEYS-IN-FACT  OR AFFILIATES UNDER OR IN CONNECTION
WITH ANY OF THE FOREGOING, INCLUDING,  WITHOUT LIMITATION,  ANY  LIABILITIES,
CLAIMS, OBLIGATIONS, LOSSES, DAMAGES,  PENALTIES, ACTIONS, JUDGMENTS, 
SUITS, COSTS, EXPENSES AND DISBURSEMENTS IMPOSED,  INCURRED OR  ASSERTED 
AS A RESULT OF THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT,  OF  THE
AGENT  AS THE ISSUER OF SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS,
EMPLOYEES,  AGENTS,  ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED  THAT  NO  LENDER
(OTHER  THAN THE AGENT AS THE ISSUER OF A LETTER OF CREDIT) SHALL BE LIABLE  FOR
THE  PAYMENT  OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES,  DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING
SOLELY  FROM  THE  GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE  AGENT  AS  THE
ISSUER  OF  A  LETTER  OF CREDIT.  THE AGREEMENTS IN THIS SECTION  2.2(d)  SHALL
SURVIVE  THE  PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION  OF
THIS AGREEMENT.

notwithstanding, no more than two separate Loans shall be outstanding at any one
time,  with,  for purposes of this Section, all Floating Rate Loans constituting
one  Loan, and all LIBO Rate Loans for the same Interest Period constituting one
Loan.   Anything herein to the contrary notwithstanding, if, on or prior to  the
determination  of  any  interest rate for any LIBO Rate Loan  for  any  Interest
Period therefor:

      (a)  the Agent determines (which determination shall be conclusive, absent
manifest  error) that quotations of interest rates for the deposits referred  to
in  the  definition of "LIBO Rate" in Section 1.2 are not being provided in  the
relevant amounts or for the relevant maturities for purposes of determining  the
rate of interest for such Loan as provided in this Agreement; or

      (b)  the Agent determines (which determination shall be conclusive, absent
manifest  error)  that the rates of interest referred to in  the  definition  of
"LIBO Rate" in Section 1.2 upon the basis of which the rate of interest for such
Loan for such Interest Period is to be determined do not accurately reflect  the
cost to the Lenders of making or maintaining such Loan for such Interest Period,

then  the  Agent  shall give the Borrower and the Lenders prompt notice  thereof
(which  notice shall be deemed rebuttably presumptive evidence of the conditions
set forth therein); and so long as such condition remains in effect, the Lenders
shall be under no obligation to make LIBO Rate Loans or to convert Floating Rate
Loans into LIBO Rate Loans, and the Borrower shall, on the last day of the  then
current Interest Period for each outstanding LIBO Rate Loan, either prepay  such
LIBO Rate Loan or convert such Loan into a Floating Rate Loan in accordance with
Section  2.13.   Before giving such notice pursuant to this Section,  the  Agent
will take such action as the Borrower may request if such action will avoid  the
need  to suspend the obligation of the Lenders to make LIBO Rate Loans hereunder
and will not, in the opinion of the Agent, be disadvantageous to the Lenders.

2.5   Use  of  Loan Proceeds and Letters of Credit.  (a) Proceeds of  the  Loans
shall be used solely for the purchase by the Borrower of certain of the Pipeline
Properties and to make loans to the Pipeline Subsidiaries for their purchase  of
the remaining Pipeline Properties.

      (b)  Letters  of Credit shall be used solely to support crude oil 
purchases  by the Borrower.

2.6   Interest.  (a) Subject to the terms of this Agreement (including,  without
limitation, Section 2.20), interest on the Loans shall accrue and be payable  at
a  rate per annum equal to the Floating Rate for each Floating Rate Loan and the
Adjusted  LIBO  Rate  for each LIBO Rate Loan.  Notwithstanding  the  foregoing,
interest  on past-due principal and, to the extent permitted by applicable  law,
past-due  interest, shall accrue at the Default Rate and shall be  payable  upon
demand  by the Agent at any time as to all or any portion of such interest.   In
the  event that the Borrower fails to select the duration of any Interest Period
for  any LIBO Rate Loan within the time period and otherwise as provided herein,
such  Loan  (if outstanding as a LIBO Rate Loan) will be automatically converted
into  a  Floating Rate Loan on the last day of the then current Interest  Period
for such Loan or (if outstanding as a Floating Rate Loan) will remain as, or (if
not  then outstanding) will be made as, a Floating Rate Loan.  Interest provided
for  herein shall be calculated on unpaid sums actually advanced and outstanding
pursuant to the terms of this Agreement and only for the period from the date or
dates of such advances until repayment.

     (b)  In the event the ratio of Total Debt to Capitalization as of the end 
of any fiscal quarter of Howell Corporation is less than or equal to .5 to 
1.0, the Borrower and Howell Corporation may give notice, in the form of Exhibit
VIII, of such  fact to the Agent.  On the Business Day following the receipt by 
the Agent of such notice, the Applicable Margin shall be reduced to one and  
one-half percent (1-1/2%).   If, at any time thereafter, the ratio of Total 
Debt to Capitalization as of the end of any fiscal quarter of Howell  
Corporation is greater than .5 to 1.0, the Borrower and Howell Corporation shall
give notice, in the form of Exhibit VIII, of such fact to the Agent.  On the 
Business Day following  the receipt by the Agent of such notice, the Applicable 
Margin  shall be  increased  to  two  percent (2%) and thereafter  shall  not  
be  subject  to reduction  as provided in the first sentence of this subsection 
until the  ratio of  Total Debt to Capitalization shall have been less than or 
equal to .5 to 1.0 for two successive fiscal quarters.

2.7   Repayment of Loans and Interest.  (a) Accrued and unpaid interest on  each
outstanding  Floating Rate Loan shall be due and payable monthly  commencing  on
the  first  day  of May, 1995, and continuing on the first day of each  calendar
month  thereafter while any Floating Rate Loan remains outstanding, the  payment
in  each  instance  to be the amount of interest which has accrued  and  remains
unpaid  in  respect of the relevant Loan.  Accrued and unpaid interest  on  each
outstanding  LIBO  Rate Loan shall be due and payable on the  last  day  of  the
Interest Period for such LIBO Rate Loan and, in the case of any Interest  Period
in  excess of three months, on the day of the third calendar month following the
commencement  of such Interest Period corresponding to the day of  the  calendar
month  on which such Interest Period commenced, the payment in each instance  to
be the amount of interest which has accrued and remains unpaid in respect of the
relevant Loan.

      (b)  The Loan Balance shall be due and payable in quarterly installments
commencing  on  the  first day of July, 1995, and continuing thereafter  on  the
first  day of each third calendar month until Final Maturity.  Such installments
shall  be  in  the amount of the lesser of the Loan Balance or One Million  Four
Hundred  Thirty-Seven  Thousand  Five Hundred Dollars  ($1,437,500).   The  Loan
Balance, together with all accrued and unpaid interest thereon, shall be due and
payable at Final Maturity.

      (c)  At the time of making each payment hereunder or under the Notes, the
Borrower  shall specify to the Agent the Loans or other amounts payable  by  the
Borrower  hereunder to which such payment is to be applied.  In  the  event  the
Borrower  fails  to so specify, or if an Event of Default has  occurred  and  is
continuing, the Agent may apply such payment as it may elect in its   discretion
and in accordance with the terms hereof.

2.8   General Terms.  (a) The outstanding principal balance of the Note of  each
Lender  reflected  in  the  records of such Lender shall  be  deemed  rebuttably
presumptive evidence of the principal amount owing on such Note.  The  liability
for payment of principal and interest evidenced by each Note shall be limited to
principal  amounts actually advanced and outstanding pursuant to this  Agreement
and interest on such amounts calculated in accordance with this Agreement.

     (b)  Unless the Agent shall have been notified by a Lender or the 
Borrower prior to the date on which either of them is scheduled to make payment 
to the Agent of (in  the  case  of a Lender) the proceeds of a Loan to be made  
by such Lender hereunder or (in the case of the Borrower) a payment to the Agent
for account of one or more of the Lenders hereunder (such payment being herein  
called the "Required  Payment"), which notice shall be effective upon  receipt,
that such Lender or the Borrower, as the case may be, does not intend to make
the Required Payment  to the Agent, the Agent may assume 
that the Required Payment  has  been made  and, in reliance upon such
assumption, may (but shall not be required  to) make  the  amount thereof
available to the intended recipient on such date.   If
such  Lender  or  the Borrower, as the case may be, has not  in  fact  made  the
Required  Payment to the Agent, the recipient of such payment shall, on  demand,
repay  to  the Agent for its account the amount so made available together  with
interest thereon in respect of each day during the period commencing on the date
such amount was so made available by the Agent until the date the Agent recovers
such  amount at a rate per annum equal to, in the case of a Lender as recipient,
the  Federal  Funds  Rate  or,  in the case of the Borrower  as  recipient,  the
Floating Rate.

2.9   Time,  Place, and Method of Payments.  All payments required  pursuant  to
this  Agreement  or the Notes shall be made without set-off or  counterclaim  in
Dollars and in immediately available funds.  All payments by the Borrower  shall
be deemed received on the next Business Day following receipt if such receipt is
after 5:00 p.m., Central Standard or Daylight Savings Time, as the case may  be,
on  any  Business  Day, and shall be made to the Agent at the Principal  Office.
Except  as  provided  to the contrary herein, if the due  date  of  any  payment
hereunder  or  under  any Note would otherwise fall on a  day  which  is  not  a
Business  Day, such date shall be extended to the next succeeding Business  Day,
and  interest shall be payable for any principal so extended for the  period  of
such extension.

2.10  Pro  Rata  Treatment; Adjustments.  (a) Except  to  the  extent  otherwise
expressly  provided herein, (i) the borrowing made pursuant  to  this  Agreement
shall be from the Lenders pro rata in accordance with their respective Term Loan
Percentage Shares, (ii) each payment by the Borrower of fees shall be  made  for
the  account  of  the Lenders pro rata in accordance with their respective  Term
Loan  Percentage Shares, (iii) each payment of principal of Loans shall be  made
for  the  account  of the Lenders pro rata in accordance with  their  respective
shares of the Loan Balance, and (iv) each payment of interest on Loans shall  be
made for the account of the Lenders pro rata in accordance with their respective
shares of the aggregate amount of interest due and payable to the Lenders.

      (b)  The Agent shall distribute all payments with respect to the 
Obligations to the  Lenders promptly upon receipt in like funds as received.  
In the event that any payments made hereunder by the Borrower at any 
particular time are insufficient to satisfy in full the Obligations due and 
payable at such time, such payments shall be applied (a) first, to fees and 
expenses due pursuant to the terms of this Agreement or any other Loan Document,
(b) second, to accrued interest, (c) third, to the Loan Balance, and 
(d) last, to any other Obligations.

      (c)  If any Lender (for purposes of this Section, a "benefitted Lender") 
shall at any time receive any payment of all or part of its portion of the
Obligations,  or receive any Collateral in respect thereof (whether  voluntarily
or  involuntarily, by set-off, pursuant to events or proceedings of  the  nature
referred  to  in  Sections 7.1(e) or 7.1(f), or otherwise) in an amount  greater
than  such  Lender  was entitled to receive pursuant to the terms  hereof,  such
benefitted Lender shall purchase for cash from the other Lenders such portion of
the  Obligations of such other Lenders or shall provide such other Lenders  with
the  benefits  of  any  such  Collateral or the proceeds  thereof  as  shall  be
necessary  to  cause  such  benefitted Lender to share  the  excess  payment  or
benefits  of  such Collateral or proceeds with each of the Lenders according  to
the  terms hereof.  If all or any portion of such excess payment or benefits  is
thereafter  recovered  from  such  benefitted Lender,  such  purchase  shall  be
rescinded  and the purchase price and benefits returned by such Lender,  to  the
extent  of  such recovery, but without interest.  The Borrower agrees that  each
such  Lender  so purchasing a portion of the Obligations of another  Lender  may
exercise  all rights of payment (including, without limitation, rights  of  set-
off)  with  respect to such portion as fully as if such Lender were  the  direct
holder  of  such  portion.  If any Lender ever receives, by  voluntary  payment,
exercise  of  rights of set-off or banker's lien, counterclaim, cross-action  or
otherwise,  any  funds  of the Borrower to be applied  to  the  Obligations,  or
receives  any proceeds by realization on or with respect to any Collateral,  all
such  funds  and  proceeds  shall be immediately  forwarded  to  the  Agent  for
distribution in accordance with the terms of this Agreement.

2.11  Borrowing Base Determinations.  (a) The Borrowing Base as of  the  Closing
Date is acknowledged by the Borrower and the Lenders to be $16,326,546.80.

      (b)  The Borrowing Base shall be redetermined monthly upon receipt by the
Lenders of each Borrowing Base Report and Receivable Report required pursuant to
Section  5.4  and shall be the amount set forth as the Borrowing  Base  in  such
Borrowing Base Report unless any Lender advises the Agent and the Borrower  that
such  Lender does not agree with the amount set forth as the Borrowing  Base  in
such  Borrowing Base Report.  In such event, the Borrowing Base in effect  prior
to  the  receipt  of  such Borrowing Base Report shall be in  effect  until  the
Lenders  shall  have  redetermined the Borrowing Base and advised  the  Borrower
thereof.   Notwithstanding  the foregoing, at the request  of  any  Lender,  the
Lenders may at their discretion redetermine the Borrowing Base at any time  and
from time to time.

      (c) The Borrowing Base shall represent the determination by the Lenders, 
in accordance with the applicable definitions and provisions herein contained 
and their customary lending practices for loans of this nature, of the  value,  
for loan purposes, of the Eligible Accounts.  Furthermore, the Borrower 
acknowledges that  the determination of the Borrowing Base contains an equity 
cushion (market value  in  excess of loan value), which is acknowledged by the  
Borrower  to  be essential for the adequate protection of the Lenders.

2.12 Mandatory Prepayments; Cash Collateral.  (a) In addition to the payments on
the  Notes  required  pursuant to Section 2.7, beginning with  the  delivery  of
Financial Statements for the fiscal quarter ending March 31, 1996, on each  date
on  which Financial Statements are required to be delivered to the Agent and the
Lenders  pursuant  to  Sections  5.2 and 5.3 (or  on  the  date  such  Financial
Statements are delivered, if earlier), the Borrower shall pay an amount equal to
60%  of  Excess Cash Flow for the previous fiscal quarter for application  as  a
prepayment on the Notes.

      (b) If at any time the L/C Exposure exceeds the lesser of the Maximum L/C
Commitment  Amount  or the Borrowing Base then in effect,  the  Borrower  shall,
within  two days of notice from the Agent of such occurrence, deposit  with  the
Agent, as additional collateral securing the Obligations, an amount of cash,  in
immediately available funds, equal to the L/C Exposure minus the lesser  of  the
Maximum  L/C  Commitment Amount or the Borrowing Base.  The cash deposited  with
the  Agent  in satisfaction of the requirement provided in this Section  may  be
invested,  at  the  sole discretion of the Agent and then only  at  the  express
direction of the Borrower as to investment vehicle and maturity (which shall  be
no  later than the latest expiry date of any then outstanding Letter of Credit),
for  the  account of the Borrower in cash or cash equivalent investments offered
by or through Bank One.

2.13  Voluntary  Prepayments and Conversions of Loans.   Subject  to  applicable
provisions of this Agreement, the Borrower shall have the right at any  time  or
from  time to time to prepay Loans and to convert Loans of one type or with  one
Interest Period into Loans of another type or with a different Interest  Period;
provided,  however, that (a) the Borrower shall give the Agent  notice  of  each
such  prepayment or conversion of all or any portion of a LIBO Rate Loan no less
than two Business Days prior to prepayment or conversion, (b) any LIBO Rate Loan
may  be prepaid or converted only on the last day of an Interest Period for such
Loan,  (c) the Borrower shall pay all accrued and unpaid interest on the amounts
of  LIBO  Rate  Loans  prepaid  or converted, and  (d)  no  such  prepayment  or
conversion shall serve to postpone the repayment when due of any Obligation.

2.14  Commitment  Fee.   (a)  To compensate the Lenders  for  maintaining  funds
available, the Borrower shall pay to the Agent for the account of the Lenders  a
fee  in  the amount of three-eighths of one percent (3/8%) per annum, calculated
on  the basis of a year of 365 or 366 days, as the case may be, and actual  days
elapsed  (including the first day but excluding the last day),  of  the  Maximum
Term  Loan Commitment Amount for the period beginning April 1, 1995, and  ending
on  the earliest of the date the Loans are made, April 30, 1995, or the date  on
which  the  Borrower  gives  notice to the Agent that  the  Borrower  wishes  to
terminate the Commitments to make Loans.  Such accrued commitment fees shall  be
payable  on the date of funding of the Loans pursuant to Section 2.1, April  30,
1995, or the date of such notice of termination by the Borrower, as the case may
be.

      (b)  The Borrower shall pay to the Agent for the account of the Lenders in
accordance  with  their  respective L/C Percentage Shares  a  letter  of  credit
commitment  fee  in  the amount of one-fourth of one percent (1/4%)  per  annum,
calculated  on the basis of a year of 365 or 366 days, as the case may  be,  and
actual days elapsed (including the first day but excluding the last day), on the
average daily amount of the Available L/C Commitment.  Accrued letter of  credit
commitment fees shall be payable on the first day of July, 1995, the  first  day
of  each third calendar month thereafter during the Commitment Period (or within
five  days following the notice from the Agent of the amount of such fee  owing,
if later), and on the Commitment Termination Date.

2.15  Facility  Fee.   To  compensate the Lenders for the  extension  of  credit
hereunder, the Borrower shall pay to the Agent for the account of the Lenders on
the Closing Date a facility fee in accordance with the terms of the Facility Fee
Letter.

2.16  Letter of Credit Fee.  The Borrower shall pay to the Agent for the account
of the Lenders in accordance with their respective L/C Percentage Shares, on the
date  of  issuance or renewal of each Letter of Credit, an issuing fee equal  to
the greater of $500 or one percent (1%) per annum, calculated on the basis of  a
year  of 365 or 366 days, as the case may be, and actual days elapsed (including
the first day but excluding the last day), on the face amount of such Letter  of
Credit  during the period for which such Letter of Credit is issued or  renewed.
The  Borrower also agrees to pay on demand to the Agent for its own  account  as
the issuer of the Letters of Credit its customary letter of credit transactional
fees  and expenses, including, without limitation, amendment fees, payable  with
respect to each Letter of Credit.

2.17  Agency  Fee.  The Borrower shall pay to the Agent for its own account  all
fees  owing  or which may become owing under the Agency Fee Letter  as  provided
therein.

2.18  Loans to Satisfy Obligations of Borrower.  The Lenders may, but shall  not
be  obligated to, make Loans for the benefit of the Borrower and apply  proceeds
thereof  to  the  satisfaction  of any condition, warranty,  representation,  or
covenant  of  the Borrower or any Guarantor contained in this Agreement  or  any
other Loan Document.  Such Loans shall be evidenced by the Notes, shall be  made
as  a Floating Rate Loan, and shall be payable upon demand.  The Agent agrees to
notify  the  Borrower of any such Loan; provided, however, the  failure  of  the
Agent  or any Lender to do so shall not subject the Agent or any Lender  to  any
liability and shall not relieve the Borrower from liability for any Obligation.

2.19  Security  Interest  in Accounts; Right of Offset.   As  security  for  the
payment  and  performance  of  the Obligations, the Borrower  hereby  transfers,
assigns,  and pledges to the Agent and each Lender and grants to the  Agent  and
each Lender a security interest in all funds of the Borrower now or hereafter or
from  time to time on deposit with the Agent or such Lender, with such  interest
of  the  Agent and the Lenders to be retransferred, reassigned, and/or released,
as  the  case may be, at the reasonable expense of the Borrower upon payment  in
full  and  complete  performance of all Obligations and the termination  of  the
Commitments.  All remedies as secured party or assignee of such funds  shall  be
exercisable  by  the  Agent and the Lenders with the verbal  consent  (confirmed
promptly in writing) of the Required Lenders upon the occurrence of any Event of
Default,  regardless of whether the exercise of any such remedy would result  in
any  penalty  or  loss of interest or profit with respect to any  withdrawal  of
funds  deposited  in  a  time deposit account prior  to  the  maturity  thereof.
Furthermore, the Borrower hereby grants to the Agent and each Lender the  right,
exercisable  at  such  time as any Event of Default shall occur,  of  offset  or
banker's lien against all funds of the Borrower now or hereafter or from time to
time  on  deposit  with  the  Agent or such Lender, regardless  of  whether  the
exercise  of any such remedy would result in any penalty or loss of interest  or
profit  with  respect to any withdrawal of funds deposited  in  a  time  deposit
account prior to the maturity thereof.

2.20  General Provisions Relating to Interest.  (a) It is the intention  of  the
parties  hereto  to  comply strictly with all applicable usury  laws.   In  this
connection,  there shall never be collected, charged, or received  on  the  sums
advanced hereunder interest in excess of that which would accrue at the  Highest
Lawful  Rate.  For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes,
as  amended,  the  Borrower agrees that the Highest Lawful  Rate  shall  be  the
"indicated (weekly) rate ceiling" as defined in such Article, provided that  the
Agent and the Lenders may also rely, to the extent permitted by applicable laws,
on alternative maximum rates of interest under other laws, if greater.

     (b)  Notwithstanding anything herein or in the Notes to the contrary, 
during any Limitation Period, the interest rate to be charged on amounts 
evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if 
any, of the Borrower for the payment of fees or other charges deemed to be 
interest under applicable law shall be suspended.  During any period or periods 
of time following a Limitation Period, to the extent permitted by applicable 
laws, the interest rate to be charged hereunder shall remain at the Highest  
Lawful Rate until such time as there has been paid to the Agent and each Lender
(i) the amount of interest in excess of that accruing at the Highest Lawful Rate
that such Lender would have received during the Limitation Period had the 
interest rate remained at the otherwise applicable rate, and (ii) all interest 
and fees otherwise  payable  to  the Agent and such Lender but for the effect  
of  such Limitation Period.

     (c) If, under any circumstances, the aggregate amounts paid on the Notes or
under this Agreement or any other Loan Document include amounts which by law are
deemed  interest  and  which would exceed the amount permitted  if  the  Highest
Lawful  Rate  were  in  effect, the Borrower stipulates that  such  payment  and
collection  will  have  been and will be deemed to  have  been,  to  the  extent
permitted  by applicable laws, the result of mathematical error on the  part  of
the  Borrower, the Agent, and the Lenders; and the party receiving  such  excess
shall  promptly  refund the amount of such excess (to the extent  only  of  such
interest payments in excess of that which would have accrued and been payable on
the basis of the Highest Lawful Rate) upon discovery of such error by such party
or  notice  thereof from the Borrower.  In the event that the  maturity  of  any
Obligation is accelerated, by reason of an election by the Lenders or otherwise,
or  in the event of any required or permitted prepayment, then the consideration
constituting interest under applicable laws may never exceed the Highest  Lawful
Rate; and excess amounts paid which by law are deemed interest, if any, shall be
credited  by  the  Agent  and  the  Lenders  on  the  principal  amount  of  the
Obligations, or if the principal amount of the Obligations shall have been  paid
in full, refunded to the Borrower.

      (d)  All sums paid, or agreed to be paid, to the Agent and the Lenders for
the use, forbearance and detention of the proceeds of any advance hereunder 
shall, to the extent permitted by applicable law, be amortized, prorated,  
allocated, and spread throughout the full term hereof until paid in full so that
the actual rate  of  interest  is  uniform  but does not exceed  the  Highest  
Lawful  Rate throughout the full term hereof.

2.21  Obligations Absolute.  Subject to the further provisions of this  Section,
the  Obligations  of  the  Borrower under this Article  shall  be  absolute  and
unconditional under any and all circumstances and irrespective of  any  set-off,
counterclaim, or defense to payment or performance which the Borrower  may  have
or  have had against the Agent, any Lender, or any beneficiary of any Letter  of
Credit.   The  Borrower agrees that none of the Agent or the  Lenders  shall  be
responsible  for, nor shall the Obligations be affected by, among other  things,
(a)  the  validity  or  genuineness of documents  or  any  endorsements  thereon
presented in connection with any Letter of Credit, even if such documents  shall
in  fact prove to be in any and all respects invalid, fraudulent or forged,  AND
EVEN  IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR  ANY
LENDER,  so  long as the Agent, as the issuer of such Letter of Credit,  has  no
actual  knowledge of any such invalidity, lack of genuineness, fraud, or forgery
prior to the presentment for payment of a corresponding Letter of Credit or  any
draft  thereunder; provided, however, with respect to the preceding  matters  in
this  Section,  the  Agent, as the issuer of the Letters of  Credit,  agrees  to
exercise  ordinary  care  in examining each document required  to  be  presented
pursuant  to each Letter of Credit to ascertain that each such document  appears
on  its  face  to comply with the terms thereof, or (b) any dispute  between  or
among  the  Borrower and any beneficiary of any Letter of Credit  or  any  other
party to which any Letter of Credit may be transferred, or any claims whatsoever
of  the  Borrower against any beneficiary of any Letter of Credit  or  any  such
transferee,  EVEN IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT,  OF  THE
AGENT OR ANY LENDER; provided, in all respects, that the Agent, as the issuer of
Letters  of Credit, shall be liable to the Borrower to the extent, but  only  to
the  extent,  of  any direct, as opposed to consequential or  punitive,  damages
suffered  by  the  Borrower  as  a result of the  willful  misconduct  or  gross
negligence  of  the  Agent  as the issuer of Letters of  Credit  in  determining
whether documents presented under a Letter of Credit complied with the terms  of
such  Letter  of  Credit that resulted in either a wrongful payment  under  such
Letter  of  Credit or a wrongful dishonor of a claim or draft properly presented
under  such  Letter  of Credit.  In the absence of gross negligence  or  willful
misconduct by the Agent as the issuer of Letters of Credit, the Agent shall  not
be  liable  for any error, omission, interruption or delay, EVEN IF DUE  TO  THE
NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT, in transmission,  dispatch
or  delivery  of any message or advice, however transmitted, in connection  with
any  Letter of Credit.  The Agent, the Lenders, and the Borrower agree that  any
action  taken or omitted by the Agent, as issuer of any Letter of Credit,  under
or  in  connection with any Letter of Credit or the related drafts or documents,
EVEN  IF DUE TO THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR  ANY
LENDER, if done in the absence of gross negligence or willful misconduct,  shall
be  binding as among the Agent, as issuer of such Letter of Credit or otherwise,
the  Lenders,  and the Borrower and shall not put the Agent, as issuer  of  such
Letter  of  Credit  or  otherwise, or any Lender  under  any  liability  to  the
Borrower.

2.22  Yield Protection.  (a) Without limiting the effect of the other provisions
of  this Section (but without duplication), the Borrower shall pay to the  Agent
and  each Lender from time to time such amounts as the Agent or such Lender  may
determine  are necessary to compensate it for any Additional Costs  incurred  by
the Agent or such Lender.

      (b)  Without limiting the effect of the other provisions of this Section  
(but without duplication), the Borrower shall pay to each Lender from time to 
time on request such amounts as such Lender may determine are necessary to  
compensate such Lender for any costs attributable to the maintenance by such 
Lender (or any Applicable  Lending Office), pursuant to any Regulatory Change,
of capital in respect of its Commitment, such compensation to include, without 
limitation, an amount equal to any reduction of the rate of return on assets or 
equity of such Lender (or any Applicable Lending Office) to a level below  that
which such Lender (or any Applicable Lending Office) could have achieved but 
for such Regulatory Change.

      (c)  Without limiting the effect of the other provisions of this Section
(but without duplication), in the event that any Requirement of  Law  or  
Regulatory Change  or the compliance by the Agent or any Lender therewith shall 
(i) impose, modify,  or hold applicable any reserve, special deposit, or similar
requirement against any Letter of Credit or obligation to issue Letters of 
Credit, or (ii) impose upon the Agent or such Lender any other condition 
regarding any Letter of Credit  or  obligation to issue Letters of Credit, and 
the result of any such event shall be to increase the cost to the Agent or such 
Lender of issuing or maintaining any Letter of Credit or obligation to issue 
Letters of Credit or any liability  with  respect to Letter of Credit Payments, 
or to reduce  any  amount receivable  in  connection therewith, 
then upon demand  by  the  Agent  or  such Lender,  as the case may be, the 
Borrower shall pay to the Agent or such Lender,from  time to time as specified
by the Agent or such Lender, additional  amounts which shall be sufficient 
to compensate the Agent or  such  Lender  for  such increased cost or 
reduced amount receivable.

      (d)  Without limiting the effect of the other provisions of this Section
(but without duplication), the Borrower shall pay to the Agent and each Lender
such amounts as shall be sufficient in the reasonable opinion of the Agent and
such Lender to compensate them for any loss, cost, or expense incurred by and  
as  a result of:

           (i)  any payment, prepayment, or conversion by the Borrower of a LIBO
Rate Loan on a date other than the last day of an Interest Period for such 
Loan; or

          (ii) any  failure  by the Borrower to borrow a LIBO Rate Loan or to  
convert a Floating Rate Loan into a LIBO Rate Loan on the date for such 
borrowing  or conversion specified in the relevant Borrowing Request;

such  compensation to include, without limitation, with respect to any LIBO Rate
Loan, an amount equal to the excess, if any, of (A) the amount of interest which
would  have accrued on the principal amount so paid, prepaid, converted, or  not
borrowed  or converted for the period from the date of such payment, prepayment,
conversion, or failure to borrow or convert to the last day of the then  current
Interest  Period  for  such Loan (or, in the case of  a  failure  to  borrow  or
convert,  the  Interest Period for such Loan which would have commenced  on  the
date  of  such failure to borrow or convert) at the applicable rate of  interest
for  such Loan provided for herein over (B) the interest component of the amount
the  Agent  or  such  Lender would have bid in the London interbank  market  for
Dollar  deposits of amounts comparable to such principal amount  and  maturities
comparable to such period, as reasonably determined by the Agent or such Lender.

      (e)  The Agent or such Lender shall determine for purposes of this Section
the effect of any Regulatory Change on capital maintained, its costs or rate  of
return,  maintaining Loans, issuing Letters of Credit, its  obligation  to  make
Loans and issue Letters of Credit, or on amounts receivable by it in respect  of
Loans,  Letters  of  Credit,  or such obligations, and  the  additional  amounts
required  to  compensate the Agent or such Lender under this Section  and  shall
furnish  the Borrower with a certificate setting forth in reasonable detail  the
basis and amount of increased costs incurred or reduced amounts receivable as  a
result  of  any  such event.  The statements set forth therein shall  be  deemed
rebuttably  presumptive  evidence of such amount.  The  Agent  or  the  relevant
Lender shall notify the Borrower, as promptly as practicable after the Agent  or
such  Lender  obtains knowledge of any Additional Costs or  other  sums  payable
pursuant to this Section and determines to request compensation therefor, of any
event  occurring  after the Closing Date which will entitle the  Agent  or  such
Lender  to  compensation  pursuant  to this Section.   If  any  Lender  requests
compensation from the Borrower under this Section, the Borrower may,  by  notice
to  the Agent and such Lender, require that the Loans by the Lender of the  type
with  respect to which such compensation is requested be converted into Floating
Rate  Loans in accordance with Section 2.13.  Any compensation requested by  the
Agent  or  any Lender pursuant to this Section shall be due and payable  to  the
Agent  or  such  Lender within five days of delivery of any such notice  to  the
Borrower.

      (f)  The Agent and the Lenders agree not to request, and the Borrower 
shall not be obligated to pay, any Additional Costs or other sums payable 
pursuant to this Section  unless  similar  additional costs  and  other  sums  
payable  are  also generally assessed by the Agent or such Lender against other 
customers similarly situated  where  such  customers are subject to  documents  
providing  for  such assessment.

2.23 Illegality.  Notwithstanding any other provision of this Agreement, in  the
event  that it becomes unlawful for any Lender or its Applicable Lending  Office
to  (a) honor its obligation to make LIBO Rate Loans, or (b) maintain LIBO  Rate
Loans,  then  such  Lender  shall promptly notify the  Agent  and  the  Borrower
thereof.   The obligation of such Lender to make LIBO Rate Loans and to  convert
Floating Rate Loans into LIBO Rate Loans shall then be suspended until such time
as  such Lender may again make and maintain LIBO Rate Loans, and the outstanding
LIBO  Rate Loans of such Lender shall be converted into Floating Rate  Loans  in
accordance  with  Section  2.13.  Before giving such  notice  pursuant  to  this
Section, such Lender will take such action as the Borrower may request  if  such
action will avoid the need to suspend the obligation of such Lender to make LIBO
Rate  Loans  and will not, in the opinion of such Lender, be disadvantageous  to
such Lender.

2.24 Taxes.  (a) All payments made by the Borrower under this Agreement shall be
made  free and clear of, and without reduction or withholding for or on  account
of,  present  or  future income, stamp or other taxes, levies, imposts,  duties,
charges, fees, deductions or withholdings, hereafter imposed, levied, collected,
withheld  or assessed by any Governmental Authority on the basis of  any  change
after  the  date  hereof  in  any applicable treaty,  law,  rule,  guideline  or
regulations  or in the interpretation or administration thereof,  excluding,  in
the case of the Agent and each Lender, net income and franchise taxes imposed on
the  Agent or such Lender by the jurisdiction under the laws of which the  Agent
or  such  Lender  is organized or any political subdivision or taxing  authority
thereof or therein, or by any jurisdiction in which such Lender's lending office
is  located or any political subdivision or taxing authority thereof or  therein
(all   such   non-excluded  taxes,  levies,  imposts,  deductions,  charges   or
withholdings being hereinafter called "Taxes").  If any Taxes are required to be
withheld from any amounts payable to the Agent or any Lender hereunder or  under
any  other  Loan  Document, the amounts so payable to the Agent or  such  Lender
shall  be increased to the extent necessary to yield to the Agent or such Lender
(after  payment  of  all  Taxes)  interest or any  such  other  amounts  payable
hereunder  at  the rates or in the amounts specified in this Agreement  and  the
other  Loan  Documents.  The Agent or the relevant Lender shall, as promptly  as
practicable after becoming aware of any Taxes, notify the Borrower thereof;  and
notwithstanding  the  foregoing, unless such Taxes  are  made  retroactive,  the
Borrower shall not be obligated for the payment of any Taxes to the extent  such
Taxes accrued more than 150 days prior to the earlier of the date of such notice
or the date on which the Borrower otherwise became aware that such Taxes were to
be  imposed.   Whenever any Taxes are payable by the Borrower,  as  promptly  as
possible thereafter, the Borrower shall send to the Agent for its own account or
for  the  account  of such Lender, as the case may be, a certified  copy  of  an
original official receipt received by the Borrower showing payment thereof.   If
the Borrower fails to pay any Taxes when due to the appropriate taxing authority
or  fails  to  remit  to  the  Agent the required  receipts  or  other  required
documentary evidence, the Borrower shall indemnify the Agent and the Lenders for
any  incremental  taxes, interest or penalties that may become  payable  by  the
Agent  or  any Lender as a result of any such failure.  The agreements  in  this
Section shall survive the termination of this Agreement and the payment  of  all
Obligations.

     (b)  Each Lender that is not incorporated under the laws of the United 
States of America  or  a state thereof agrees that, prior to the first date on  
which any payment  is due to it hereunder, it will, to the extent it may 
lawfully  do  so, deliver to the Borrower and the Agent two duly completed 
copies of United States Internal Revenue Service Form 1001 or 4224 or successor
applicable form, as  the case  may  be, certifying in each case that such Lender
is entitled  to  receive payments  under this Agreement and the Note payable to 
it, without deduction  or withholding  of any United States federal income 
taxes.  At the written  request of the Borrower, each Lender which delivers to 
the Borrower and the Agent a Form 1001 or 4224 pursuant to the preceding 
sentence further undertakes to deliver to the  Borrower  and the Agent two 
further copies of such Form 1001  or  4224,  or successor  applicable forms, or 
other manner of certification, as the  case  may be,  on  or  before  the date 
that any such letter or form  expires  or  becomes obsolete  or  after the 
occurrence of any event requiring a change in  the  most
recent  form previously delivered by it to the Borrower, and such extensions  or
renewals  thereof as may reasonably be requested by the Borrower, certifying  in
the  case  of Form 1001 or 4224 that such Lender is entitled to receive payments
under  this  Agreement  without deduction or withholding of  any  United  States
federal  income  taxes,  unless in any such case, an event  (including,  without
limitation, any change in treaty, law or regulation) has occurred prior  to  the
date  on  which any such delivery would otherwise be required which renders  all
such  forms inapplicable or which would prevent such Lender from duly completing
and  delivering  any  such form with respect to it and such Lender  advises  the
Borrower  that it is not capable of receiving payments without any deduction  or
withholding of United States federal income tax.

2.25  Replacement Lenders.  (a) If any Lender has notified the Borrower  of  its
incurring additional costs under Section 2.22 or that, pursuant to Section  2.23
or  2.26, its obligation to make or maintain LIBO Rate Loans is to be suspended,
or  has required the Borrower to make payments for Taxes under Section 2.24, the
Borrower   may,  unless  such  Lender  has  notified  the  Borrower   that   the
circumstances  giving rise to such notice no longer apply, terminate,  in  whole
but  not  in  part,  the Commitment of any Lender (other than  the  Agent)  (the
"Terminated  Lender") at any time upon five Business Days' prior written  notice
to  the  Terminated Lender and the Agent (such notice referred to  herein  as  a
"Notice of Termination").

     (b)  In order to effect the termination of the Commitment of the Terminated
Lender,  the  Borrower shall (i) with the consent of Lenders  holding  at  least
seventy  percent  (70%) of the Loan Balance, without regard to  any  sale  of  a
participation  in  any Loan and exclusive of the portion  of  the  Loan  Balance
outstanding  to the Terminated Lender, pay to the Agent for the account  of  the
Terminated  Lender only, all amounts owing to such Terminated Lender  under  the
Loan Documents, or (ii) obtain an agreement with one or more Lenders to increase
their  Commitments and/or request any one or more other banking institutions  to
become  a  "Lender" in place and instead of such Terminated Lender and agree  to
accept a Commitment; provided, however, that such other banking institutions are
reasonably acceptable to the Agent and become parties by executing an Assignment
Agreement  (the Lenders or other banking institutions that agree  to  accept  in
whole  or  in  part  the Commitment of the Terminated Lender being  referred  to
herein  as the "Replacement Lenders"), such that the aggregate increased  and/or
accepted  L/C  Commitment  Amounts  and Term  Loan  Commitment  Amounts  of  the
Replacement  Lenders  equal the L/C Commitment Amount and Term  Loan  Commitment
Amount, respectively, of the Terminated Lender.

      (c)  The Notice of Termination shall include the name of the Terminated 
Lender, the date the termination will occur (the "Termination Date"), the  
Replacement Lender  or  Replacement Lenders to which the Terminated Lender will 
assign  its Commitment, and, if there will be more than one Replacement Lender, 
the  portion of the Terminated Lender's Commitment to be assigned to each 
Replacement Lender.

      (d)  On the Termination Date, (i) the Terminated Lender shall by execution
and delivery of an Assignment Agreement assign its Commitment to the Replacement
Lender  or  Replacement Lenders (pro rata, if there is more than one Replacement
Lender, in proportion to the portion of the Terminated Lender's Commitment to be
assigned to each Replacement Lender) indicated in the Notice of Termination  and
shall assign to the Replacement Lender or Replacement Lenders its Loan (if  any)
then  outstanding  pro  rata  as aforesaid), (ii) the  Terminated  Lender  shall
endorse  its Note, payable without recourse, representation or warranty  to  the
order  of the Replacement Lender or Replacement Lenders (pro rata as aforesaid),
(iii) the Replacement Lender or Replacement Lenders shall purchase the Note held
by  the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid
principal  amount  thereof  plus interest and fees accrued  and  unpaid  to  the
Termination  Date, and (iv) the Replacement Lender or Replacement  Lenders  will
thereupon (pro rata as aforesaid) succeed to and be substituted in all  respects
for  the Terminated Lender with like effect as if becoming a Lender pursuant  to
the  terms of Section 9.1(b), and the Terminated Lender will have the rights and
benefits  of  an assignor under Section 9.1(b).  To the extent not in  conflict,
the terms of Section 9.1(b) shall supplement the provisions of this Section.

2.26 Regulatory Change. In the event that by reason of any Regulatory Change  or
any other circumstance arising after the Closing Date affecting any Lender, such
Lender (a) incurs Additional Costs (other than those incurred as a result of  an
increase in the Reserve Requirement) based on or measured by the excess above  a
specified level of the amount of a category of deposits or other liabilities  of
such  Lender which includes deposits by reference to which the interest rate  on
any LIBO Rate Loan is determined as provided in this Agreement or a category  of
extensions of credit or other assets of such Lender which includes any LIBO Rate
Loan, or (b) becomes subject to restrictions on the amount of such a category of
liabilities  or assets which it may hold, then, at the election of  such  Lender
with notice to the Agent and the Borrower, the obligation of such Lender to make
LIBO Rate Loans and to convert Floating Rate Loans into LIBO Rate Loans shall be
suspended until such time as such Regulatory Change or other circumstance ceases
to  be  in  effect, and all such outstanding LIBO Rate Loans shall be  converted
into Floating Rate Loans in accordance with Section 2.13.

                         REPRESENTATIONS AND WARRANTIES

           To  induce the Agent and the Lenders to enter into this Agreement and
to  extend credit to the Borrower, the Borrower represents and warrants  to  the
Agent  and  each Lender (which representations and warranties shall survive  the
delivery of the Notes) that:

4.1   Due  Authorization.  The execution and delivery by the  Borrower  of  this
Agreement  and  the  borrowings hereunder, the execution  and  delivery  by  the
Borrower  of the Notes and the other Loan Documents, the repayment of the  Notes
and  interest  and  fees provided for in the Notes and this Agreement,  and  the
performance  of  all  obligations of the Borrower under the Loan  Documents  are
within  the  power of the Borrower, have been duly authorized by  all  necessary
corporate  action  by  the Borrower, and do not and will  not  (a)  require  the
consent  of  any  Governmental Authority, (b) contravene or  conflict  with  any
Requirement  of Law, (c) contravene or conflict with any indenture,  instrument,
or  other agreement to which the Borrower is a party or by which any Property of
the  Borrower may be presently bound or encumbered, or (d) result in or  require
the  creation  or  imposition of any Lien in, upon or of  any  Property  of  the
Borrower other than as contemplated by the Loan Documents.

4.2  Corporate Existence.  The Borrower is a corporation duly organized, legally
existing, and in good standing under the laws of its state of incorporation  and
is  duly  qualified  as  a foreign corporation and is in good  standing  in  all
jurisdictions wherein the ownership of Property or the operation of its business
necessitates  same, other than those jurisdictions wherein  the  failure  to  so
qualify will not have a Material Adverse Effect.

4.3  Valid and Binding Obligations.  All Loan Documents to which the Borrower is
a  party,  when duly executed and delivered by the Borrower, will be the  legal,
valid, and binding obligations of the Borrower, enforceable against the Borrower
in accordance with their respective terms.

4.4   Security Instruments.  The provisions of each Security Instrument executed
by  the  Borrower are effective to create in favor of the Agent, a legal, valid,
and  enforceable Lien in all right, title, and interest of the Borrower  in  the
Collateral  described  therein,  which Liens,  assuming  the  accomplishment  of
recording  and  filing  in  accordance  with  applicable  laws  prior   to   the
intervention  of  rights  of  other Persons, shall  constitute  fully  perfected
first-priority  Liens on all right, title, and interest of the Borrower  in  the
Collateral described therein.

4.5   Title to Assets.  The Borrower has good and indefeasible title to  all  of
its Properties, free and clear of all Liens except Permitted Liens.

4.6   Scope  and Accuracy of Financial Statements.  The Financial Statements  of
the Borrower as of September 30, 1994, present fairly the financial position and
results  of  operations and cash flows of the Borrower in accordance  with  GAAP
(except for the omission of footnotes and provision for income taxes) as at  the
relevant  point in time or for the period indicated, as applicable,  subject  to
normal year-end audit adjustments.  No event or circumstance has occurred  since
September  30,  1994,  which could reasonably be expected  to  have  a  Material
Adverse Effect.

4.7   No  Material Misstatements.  No information, exhibit, statement, or report
furnished  to the Agent or any Lender by or at the direction of the Borrower  in
connection  with this Agreement contains any material misstatement  of  fact  or
omits  to  state  a material fact or  any fact necessary to make the  statements
contained therein not misleading as of the date made or deemed made in light  of
the circumstances in which they were made.

4.8   Liabilities, Litigation, and Restrictions.  Other than as disclosed in the
Financial Statements provided to the Lenders on or before the Closing Date,  the
Borrower  has  no liabilities, direct, or contingent, which may  materially  and
adversely  affect its business or operations or its ownership of the Collateral.
Except as disclosed in writing to the Lenders on the Closing Date, no litigation
or  other  action of any nature affecting the Borrower in which  the  amount  in
controversy exceeds $100,000 is pending before any Governmental Authority or, to
the  best  knowledge  of  the  Borrower, threatened  against  or  affecting  the
Borrower.   No  unusual or unduly burdensome restriction,  restraint  or  hazard
exists by contract, Requirement of Law, or otherwise relative to the business or
operations  of  the  Borrower or the ownership and operation of  the  Collateral
other  than  such as relate generally to Persons engaged in business  activities
similar to those conducted by the Borrower, the effect of which could reasonably
be expected to have a Material Adverse Effect.

4.9   Authorizations;  Consents.   Except  as  expressly  contemplated  by  this
Agreement, no authorization, consent, approval, exemption, franchise, permit, or
license  of, or filing with, any Governmental Authority or any other  Person  is
required  to  authorize or is otherwise required in connection  with  the  valid
execution  and delivery by the Borrower of the Loan Documents or any  instrument
contemplated hereby, the repayment by the Borrower of the Notes and interest and
fees  provided in the Notes and the other Loan Documents, or the performance  by
the Borrower of the Obligations.

4.10 Compliance with Laws.  The Borrower and its Property are in compliance with
all applicable Requirements of Law, including, without limitation, Environmental
Laws,  the Natural Gas Policy Act of 1978, as amended, and ERISA, except to  the
extent non-compliance with any such Requirements of Law could not reasonably  be
expected to have a Material Adverse Effect.

4.11  ERISA.   No  Reportable  Event has occurred with  respect  to  any  Single
Employer  Plan,  and  each  Single Employer Plan  has  complied  with  and  been
administered  in all material respects in accordance with applicable  provisions
of ERISA and the Code.  To the best knowledge of the Borrower, (a) no Reportable
Event  has  occurred  with  respect  to any Multiemployer  Plan,  and  (b)  each
Multiemployer  Plan  has  complied with and been administered  in  all  material
respects with applicable provisions of ERISA and the Code.  The present value of
all  benefits vested under each Single Employer Plan maintained by the  Borrower
or  any  Commonly Controlled Entity (based on the assumptions used to fund  such
Plan)  did not, as of the last annual valuation date applicable thereto,  exceed
the value of the assets of such Plan allocable to such vested benefits.  Neither
the  Borrower nor any Commonly Controlled Entity has had a complete  or  partial
withdrawal  from  any  Multiemployer Plan for  which  there  is  any  withdrawal
liability.  As of the most recent valuation date applicable to any Multiemployer
Plan,  neither  the  Borrower nor any Commonly Controlled  Entity  would  become
subject to any liability under ERISA if the Borrower or such Commonly Controlled
Entity  were  to withdraw completely from such Multiemployer Plan.  Neither  the
Borrower  nor  any  Commonly  Controlled Entity has  received  notice  that  any
Multiemployer Plan is Insolvent or in Reorganization.  To the best knowledge  of
the  Borrower,  no  such Insolvency or Reorganization is  reasonably  likely  to
occur.   The  Borrower has no reason to believe that the annual cost during  the
term of this Agreement to the Borrower and all Commonly Controlled Entities  for
post-retirement benefits to be provided to the current and former  employees  of
the  Borrower and all Commonly Controlled Entities under Plans which are welfare
benefit plans (as defined in Section 3(1) of ERISA) will, in the aggregate, have
a Material Adverse Effect.

4.12  Environmental  Laws.  (a) No Property of the Borrower or  either  Pipeline
Subsidiary  is  currently on or has ever been on, or, to the  knowledge  of  the
Borrower,  is  adjacent to any Property which is on or has  ever  been  on,  any
federal or state list of Superfund Sites.

      (b)  To the knowledge of the Borrower, no Hazardous Substances have been
generated,  transported, and/or disposed of by the Borrower or  either  Pipeline
Subsidiary  at a site which was, at the time of such generation, transportation,
and/or disposal, or has since become, a Superfund Site.

      (c)  No Release of Hazardous Substances by the Borrower or either Pipeline
Subsidiary  or  from, affecting, or related to any Property of the  Borrower  or
either Pipeline Subsidiary or, to the knowledge of the Borrower, adjacent to any
Property of the Borrower or either Pipeline Subsidiary has occurred which  could
reasonably be expected to have a Material Adverse Effect.

     (d)  No Environmental Complaint has been received by the Borrower or either
Pipeline Subsidiary which has not been satisfactorily resolved.

4.13  Compliance with Federal Reserve Regulations.  No transaction  contemplated
by  the  Loan  Documents is in violation of any regulations promulgated  by  the
Board of Governors of the Federal Reserve System, including, without limitation,
Regulations G, T, U, or X.

4.14  Investment  Company  Act Compliance.  The Borrower  is  not,  nor  is  the
Borrower directly or indirectly controlled by or acting on behalf of any  Person
which  is,  an "investment company" or an "affiliated person" of an  "investment
company" within the meaning of the Investment Company Act of 1940, as amended.

4.15  Public  Utility Holding Company Act Compliance.  The  Borrower  is  not  a
"holding  company," or an "affiliate" of a "holding company" or of a "subsidiary
company"  of  a  "holding company," within the meaning  of  the  Public  Utility
Holding Company Act of 1935, as amended.

4.16  Proper  Filing of Tax Returns; Payment of Taxes Due.   All  United  States
income  tax returns and all other tax returns which are required to be filed  on
behalf of the Borrower have been filed, and all taxes owing by the Borrower  and
the  Guarantors have been paid except such as are being contested in good  faith
and as to which adequate provisions and disclosures have been made in accordance
with GAAP.  The respective charges and reserves on the books of the Borrower and
the  Guarantors  with  respect  to  taxes and  other  governmental  charges  are
adequate.

4.17  Intellectual  Property.  The Borrower owns  or  is  licensed  to  use  all
Intellectual  Property  necessary  to  conduct  all  business  material  to  its
condition (financial or otherwise), business, or operations as such business  is
currently  conducted.  No claim has been asserted or is pending  by  any  Person
with the respect to the use of any such Intellectual Property or challenging  or
questioning the validity or effectiveness of any such Intellectual Property; and
the  Borrower  knows  of no valid basis for any such claim.   The  use  of  such
Intellectual  Property by the Borrower does not infringe on the  rights  of  any
Person,  except  for such claims and infringements as do not, in the  aggregate,
give rise to any material liability on the part of the Borrower.

4.18  Casualties or Taking of Property.  Since September 30, 1994,  neither  the
business nor any Property of the Borrower has been materially adversely affected
as  a  result  of  any  fire, explosion, earthquake, flood, drought,  windstorm,
accident,  strike or other labor disturbance, embargo, requisition or taking  of
Property,  or  cancellation  of  contracts,  permits,  or  concessions  by   any
Governmental Authority, riot, activities of armed forces, or acts of God.

4.19 Locations of Borrower.  The principal place of business and chief executive
office  of the Borrower is located at the address of the Borrower set  forth  on
the  signature pages hereof or at such other location as the Borrower may  have,
by  proper written notice hereunder, advised the Agent and the Lenders, provided
that  such  other  location  is  within a state in which  appropriate  financing
statements from the Borrower in favor of the Agent have been filed.

4.20  Subsidiaries.  The Borrower has no Subsidiaries except  for  the  Pipeline
Subsidiaries,  the  Pipeline  Subsidiaries  have  no  Subsidiaries,  and  Howell
Corporation has no Subsidiaries except those described on Exhibit XI  under  the
heading "Subsidiaries of Howell Corporation."

5.9   Payment  of  Assessments  and  Charges.   Pay,  and  cause  each  Pipeline
Subsidiary to pay, all taxes, assessments, governmental charges, rent, and other
Indebtedness which, if unpaid, might become a Lien against the Property  of  the
Borrower  or  either  Pipeline Subsidiary, except any  of  the  foregoing  being
contested in good faith and as to which adequate reserve in accordance with GAAP
has  been established or unless failure to pay would not have a Material Adverse
Effect; and provide evidence satisfactory to the Agent of the payment by  Howell
Corporation  of its obligations to the Department of Energy promptly  after  the
making of each such payment by Howell Corporation.

5.10  Maintenance  of  Corporate  Existence and  Good  Standing.   Maintain  its

incurred by the Agent or such Lender until the date it is repaid to the Agent or
such  Lender,  with  the  obligations under  this  Section  surviving  the  non-
assumption of this Agreement in a case commenced under any Insolvency Proceeding
and  being  binding upon the Borrower and/or a trustee, receiver, custodian,  or
liquidator of the Borrower appointed in any such case.

Pipeline  Subsidiary  to  maintain and operate, its  Pipeline  Properties  in  a
prudent and workmanlike manner in accordance with industry standards.

5.14  Maintenance  and  Inspection  of Properties.   Maintain,  and  cause  each
Pipeline  Subsidiary to maintain, all of its tangible Properties in good  repair

failure  to  do  so  would not have a Material Adverse Effect;  and  permit  any
authorized  representative of the Agent or any Lender to visit and  inspect,  at
the  expense  of the Borrower, any tangible Property of the Borrower  or  either
Pipeline Subsidiary.

5.15 Maintenance of Insurance.  Maintain, and cause each Pipeline Subsidiary  to
maintain,  insurance with respect to its Properties and businesses against  such

other  times  upon  request  by  the  Agent,  furnish  to  the  Agent  evidence,
satisfactory  to  the  Agent, of the maintenance of such insurance.   The  Agent

any  and  all  monies  that may become payable under any policies  of  insurance
relating  to  business interruption or by reason of damage, loss, or destruction
of  any of the Collateral.  In the event of any damage, loss, or destruction for
which  insurance proceeds relating to business interruption or Collateral exceed
$250,000, the Agent may, at its option, apply all such sums or any part  thereof
received  by  it  toward  the  payment of the Obligations,  whether  matured  or
unmatured,  application to be made first to interest and then to principal,  and
shall  deliver  to the Borrower the balance, if any, after such application  has
been  made.   In  the event of any such damage, loss, or destruction  for  which
insurance  proceeds are $250,000 or less, provided that no Default or  Event  of
Default  has  occurred  and  is continuing, the Agent  shall  deliver  any  such
proceeds  received  by  it  to the Borrower.  In the event  the  Agent  receives
insurance proceeds not attributable to Collateral or business interruption,  the
Agent shall deliver any such proceeds to the Borrower.

5.16 Maintenance of Operating Accounts.  Maintain its primary operating accounts
with Bank One.

5.17 Indemnification.  INDEMNIFY AND HOLD THE AGENT AND EACH OF THE LENDERS  AND
THEIR RESPECTIVE SHAREHOLDERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, 
ATTORNEYS-IN-FACT, AND  AFFILIATES AND EACH TRUSTEE FOR THE BENEFIT OF THE AGENT
OR  THE LENDERS  UNDER  ANY SECURITY INSTRUMENT HARMLESS FROM AND AGAINST  ANY

PRESENCE  OF  ANY  HAZARDOUS SUBSTANCES ON, UNDER, OR FROM ANY PROPERTY  OF  THE
BORROWER  OR  EITHER PIPELINE SUBSIDIARY, WHETHER PRIOR TO OR  DURING  THE  TERM
HEREOF, (b) ANY ACTIVITY CARRIED ON OR UNDERTAKEN ON OR OFF ANY PROPERTY OF  THE

PREDECESSOR  IN  TITLE,  EMPLOYEE, AGENT, CONTRACTOR, OR  SUBCONTRACTOR  OF  THE
BORROWER,  EITHER PIPELINE SUBSIDIARY, OR ANY OTHER PERSON AT ANY TIME OCCUPYING
OR  PRESENT  ON  SUCH  PROPERTY,  IN CONNECTION WITH  THE  HANDLING,  TREATMENT,

OF  CREDIT  OF  A  WRONGFUL DISHONOR BY THE AGENT OF A CLAIM OR DRAFT  PRESENTED
THEREUNDER,  OR ANY OTHER ACT OR OMISSION IN CONNECTION WITH OR RELATED  TO  ANY
LOAN  DOCUMENT  OR  THE  TRANSACTIONS CONTEMPLATED THEREBY,  INCLUDING,  WITHOUT
LIMITATION,  ANY  OF  THE  FOREGOING IN THIS SECTION  ARISING  FROM  NEGLIGENCE,

                                  ARTICLE VIII
                                        
                                    THE AGENT

8.1   Appointment.  Each Lender hereby designates and appoints the Agent as  the
agent  of  such Lender under this Agreement and the other Loan Documents.   Each
Lender  authorizes the Agent, as the agent for such Lender, to take such  action
on  behalf  of such Lender under the provisions of this Agreement and the  other
Loan  Documents  and  to exercise such powers and perform  such  duties  as  are
expressly  delegated to the Agent by the terms of this Agreement and  the  other
Loan  Documents,  together with such other powers as are  reasonably  incidental
thereto.   Notwithstanding  any  provision to the  contrary  elsewhere  in  this
Agreement or in any other Loan Document, the Agent shall not have any duties  or
responsibilities except those expressly set forth herein or in  any  other  Loan
Document  or  any  fiduciary  relationship  with  any  Lender;  and  no  implied
covenants,  functions, responsibilities, duties, obligations, or liabilities  on
the  part  of  the  Agent shall be read into this Agreement or  any  other  Loan
Document or otherwise exist against the Agent.

8.2   Delegation of Duties.  The Agent may execute any of its duties under  this
Agreement and the other Loan Documents by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining  to
such  duties.   The  Agent  shall  not  be responsible  for  the  negligence  or
misconduct  of  any agents or attorneys-in-fact selected by it  with  reasonable
care.

8.3   Exculpatory  Provisions.   Neither the Agent  nor  any  of  its  officers,
directors,  employees,  agents, attorneys-in-fact or  affiliates  shall  be  (a)
required  to  initiate  or  conduct  any litigation  or  collection  proceedings
hereunder,  except with the concurrence of the Required Lenders and contribution
by each Lender of its Term Loan Percentage Share of costs reasonably expected by
the  Agent  to  be incurred in connection therewith, (b) liable for  any  action
lawfully  taken  or  omitted  to be taken by it  or  such  Person  under  or  in
connection  with  this Agreement or any other Loan Document  (except  for  gross
negligence  or  willful  misconduct  of  the  Agent  or  such  Person),  or  (c)
responsible   in  any  manner  to  any  Lender  for  any  recitals,  statements,
representations  or  warranties  made by the Borrower  or  any  officer  thereof
contained  in  this Agreement or any other Loan Document or in any  certificate,
report,  statement or other document referred to or provided for in, or received
by  the  Agent  under or in connection with, this Agreement or  any  other  Loan
Document,  or  for the sufficiency, accuracy, or completeness of  any  materials
provided  by the Agent, or the failure of the Agent to provide any materials  or
disclose any matter to any Lender except as may be expressly required herein, or
for   the   value,  validity,  effectiveness,  genuineness,  enforceability   or
sufficiency of this Agreement or any other Loan Document or for any  failure  of
the  Borrower  to  perform its obligations hereunder or thereunder.   The  Agent
shall not be under any obligation to any Lender to ascertain or to inquire as to
the  observance  or  performance  of any of  the  agreements  contained  in,  or
conditions  of,  this Agreement or any other Loan Document, or  to  inspect  the
properties, books or records of the Borrower.

8.4  Reliance by Agent.  The Agent shall be entitled to rely, and shall be fully
protected  in  relying,  upon  any Note, writing, resolution,  notice,  consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine  and correct and to have been signed, sent or made by the proper  Person
or  Persons and upon advice and statements of legal counsel (including,  without
limitation, counsel to the Borrower), independent accountants and other  experts
selected  by the Agent.  The Agent may deem and treat the payee of any  Note  as
the  owner  thereof  for  all  purposes unless and until  a  written  notice  of
assignment,  negotiation, or transfer thereof shall have been  received  by  the
Agent.   The Agent shall be fully justified in failing or refusing to  take  any
action  under  this Agreement or any other Loan Document unless it  shall  first
receive  such  advice  or  concurrence of  the  Required  Lenders  as  it  deems
appropriate and contribution by each Lender of its Term Loan Percentage Share of
costs  reasonably expected by the Agent to be incurred in connection  therewith.
The Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement and the other Loan Documents in accordance  with  a
request  of the Required Lenders.  Such request and any action taken or  failure
to act pursuant thereto shall be binding upon the Lenders and all future holders
of  the Notes.  In no event shall the Agent be required to take any action  that
exposes the Agent to personal liability or that is contrary to any Loan Document
or applicable Requirement of Law.

8.5   Notice  of  Default.  The Agent shall not be deemed to have  knowledge  or
notice of the occurrence of any Default or Event of Default unless the Agent has
received  notice  from  a Lender or the Borrower referring  to  this  Agreement,
describing  such Default or Event of Default and stating that such notice  is  a
"notice  of  default."  In the event that the Agent receives such a notice,  the
Agent  shall promptly give notice thereof to the Lenders.  The Agent shall  take
such  action  with  respect to such Default or Event  of  Default  as  shall  be
reasonably directed by the Required Lenders; provided that unless and until  the
Agent  shall have received such directions, subject to the provisions of Section
7.2,  the Agent may (but shall not be obligated to) take such action, or refrain
from taking such action, with respect to such Default or Event of Default as  it
shall  deem  advisable in the best interests of the Lenders.  In the event  that
the officer of the Agent primarily responsible for the lending relationship with
the  Borrower or the officer of any Lender primarily responsible for the lending
relationship with the Borrower becomes aware that a Default or Event of  Default
has  occurred and is continuing, the Agent or such Lender, as the case  may  be,
shall  use its good faith efforts to inform the other Lenders and/or the  Agent,
as  the case may be, promptly of such occurrence.  Notwithstanding the preceding
sentence, failure to comply with the preceding sentence shall not result in  any
liability to the Agent or any Lender.

8.6    Non-Reliance   on  Agent  and  Other  Lenders.   Each  Lender   expressly
acknowledges  that  neither the Agent nor any other  Lender  nor  any  of  their
respective   officers,   directors,  employees,  agents,  attorneys-in-fact   or
affiliates  has made any representation or warranty to such Lender and  that  no
act  by  the Agent or any other Lender hereafter taken, including any review  of
the affairs of the Borrower, shall be deemed to constitute any representation or
warranty by the Agent or any Lender to any other Lender.  Each Lender represents
to  the Agent that it has, independently and without reliance upon the Agent  or
any  other Lender, and based on such documents and information as it has  deemed
appropriate,  made  its own appraisal of and investigation  into  the  business,
operations,  property, condition (financial and otherwise) and  creditworthiness
of  the  Borrower  and the value of the Collateral and other Properties  of  the
Borrower  and  has  made its own decision to enter into  this  Agreement.   Each
Lender also represents that it will, independently and without reliance upon the
Agent  or  any  other Lender and based on such documents and information  as  it
shall  deem  appropriate at the time, continue to make its own credit  analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the  other  Loan Documents, and to make such investigation as it deems necessary
to  inform itself as to the business, operations, property, condition (financial
and  otherwise)  and  creditworthiness of the Borrower  and  the  value  of  the
Collateral  and  other Properties of the Borrower.  Except for notices,  reports
and  other  documents expressly required to be furnished to the Lenders  by  the
Agent  hereunder, the Agent shall not have any duty or responsibility to provide
any  Lender  with  any  credit  or other information  concerning  the  business,
operations,  property, condition (financial and otherwise), or  creditworthiness
of  the  Borrower  or  the value of the Collateral or other  Properties  of  the
Borrower which may come into the possession of the Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

8.7   Indemnification.   EACH  LENDER AGREES TO  INDEMNIFY  THE  AGENT  AND  ITS
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT AND AFFILIATES (TO THE
EXTENT NOT REIMBURSED BY THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE
BORROWER TO DO SO), RATABLY ACCORDING TO THE TERM LOAN PERCENTAGE SHARE OF  SUCH
LENDER,  FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS, OBLIGATIONS,  LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS
OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME (INCLUDING, WITHOUT LIMITATION, ANY
TIME  FOLLOWING  THE  PAYMENT  AND  PERFORMANCE  OF  ALL  OBLIGATIONS  AND   THE
TERMINATION  OF  THIS AGREEMENT) BE IMPOSED ON, INCURRED BY OR ASSERTED  AGAINST
THE   AGENT   OR   ANY   OF   ITS   OFFICERS,  DIRECTORS,   EMPLOYEES,   AGENTS,
ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR ARISING  OUT  OF  THIS
AGREEMENT  OR  ANY  OTHER LOAN DOCUMENT, OR ANY OTHER DOCUMENT  CONTEMPLATED  OR
REFERRED  TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY ACTION  TAKEN
OR  OMITTED  BY THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES,  AGENTS,
ATTORNEYS-IN-FACT  OR  AFFILIATES  UNDER  OR  IN  CONNECTION  WITH  ANY  OF  THE
FOREGOING,  INCLUDING, WITHOUT LIMITATION, ANY LIABILITIES, CLAIMS, OBLIGATIONS,
LOSSES,  DAMAGES,  PENALTIES, ACTIONS, JUDGMENTS,  SUITS,  COSTS,  EXPENSES  AND
DISBURSEMENTS  IMPOSED,  INCURRED OR ASSERTED AS A  RESULT  OF  THE  NEGLIGENCE,
WHETHER  SOLE  OR  CONCURRENT, OF THE AGENT OR ANY OF ITS  OFFICERS,  DIRECTORS,
EMPLOYEES,  AGENTS,  ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED  THAT  NO  LENDER
SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS,
LOSSES,  DAMAGES,  PENALTIES,  ACTIONS, JUDGMENTS,  SUITS,  COSTS,  EXPENSES  OR
DISBURSEMENTS  RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL  MISCONDUCT
OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-
FACT  OR  AFFILIATES.  THE AGREEMENTS IN THIS SECTION SHALL SURVIVE THE  PAYMENT
AND PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

8.8   Restitution.  Should the right of the Agent or any Lender to realize funds
with  respect to the Obligations be challenged and any application of such funds
to  the Obligations be reversed, whether by Governmental Authority or otherwise,
or  should  the  Borrower otherwise be entitled to a refund or return  of  funds
distributed to the Lenders in connection with the Obligations, the Agent or such
Lender, as the case may be, shall promptly notify the Lenders of such fact.  Not
later than Noon, Central Standard or Daylight Savings Time, as the case may  be,
of the Business Day following such notice, each Lender shall pay to the Agent an
amount  equal  to the ratable share of such Lender of the funds required  to  be
returned  to the Borrower.  The ratable share of each Lender shall be determined
on  the  basis  of the percentage of the payment all or a portion  of  which  is
required  to  be  refunded  originally  distributed  to  such  Lender,  if  such
percentage  can  be determined, or, if such percentage cannot be determined,  on
the  basis  of the Term Loan Percentage Share of such Lender.  The  Agent  shall
forward  such  funds to the Borrower or to the Lender required  to  return  such
funds.   If  any  such amount due to the Agent is made available by  any  Lender
after  Noon, Central Standard or Daylight Savings Time, as the case may  be,  of
the  Business Day following such notice, such Lender shall pay to the Agent  (or
the Lender required to return funds to the Borrower, as the case may be) for its
own  account interest on such amount at a rate equal to the Federal  Funds  Rate
for  the period from and including the date on which restitution to the Borrower
is made by the Agent (or the Lender required to return funds to the Borrower, as
the  case may be) to but not including the date on which such Lender failing  to
timely forward its share of funds required to be returned to the Borrower  shall
have made its ratable share of such funds available.

8.9   Agent in Its Individual Capacity.  The Agent and its affiliates  may  make
loans to, accept deposits from and generally engage in any kind of business with
the Borrower as though the Agent were not the agent hereunder.  With respect  to
any  Note  issued to the Lender serving as the Agent, the Agent shall  have  the
same  rights  and powers under this Agreement as a Lender and may exercise  such
rights  and  powers  as though it were not the Agent.  The  terms  "Lender"  and
"Lenders" shall include the Agent in its individual capacity.

8.10  Successor Agent.  The Agent may resign as Agent upon ten days'  notice  to
the  Lenders  and the Borrower.  If the Agent shall resign as Agent  under  this
Agreement  and  the  other  Loan Documents, Lenders  for  which  the  Term  Loan
Percentage Shares aggregate at least 60% shall appoint from among the Lenders  a
successor agent for the Lenders, whereupon such successor agent shall succeed to
the  rights, powers and duties of the Agent.  The term "Agent" shall  mean  such
successor agent effective upon its appointment.  The rights, powers, and  duties
of  the  former Agent as Agent shall be terminated, without any other or further
act  or  deed  on  the part of such former Agent or any of the parties  to  this
Agreement or any holders of the Notes.  After the removal or resignation of  any
Agent  hereunder  as  Agent, the provisions of this Article  VIII  and  Sections
2.2(d),  5.12,  and 5.17 shall inure to its benefit as to any actions  taken  or
omitted to be taken by it while it was Agent under this Agreement and the  other
Loan Documents.

8.11  Applicable  Parties.  The provisions of this Article are  solely  for  the
benefit of the Agent and the Lenders, and the Borrower shall not have any rights
as  a  third party beneficiary or otherwise under any of the provisions of  this
Article.  In performing functions and duties hereunder and under the other  Loan
Documents, the Agent shall act solely as the agent of the Lenders and  does  not
assume,  nor  shall it be deemed to have assumed, any obligation or relationship
of  trust  or  agency  with  or for the Borrower or  any  legal  representative,
successor, and assign of the Borrower.

                                   ARTICLE IX
                                        
                                  MISCELLANEOUS

9.1   Assignments; Participations.  (a) The Borrower may not assign any  of  its
rights  or obligations under any Loan Document without the prior consent of  the
Agent and the Lenders.

      (b)  Except pursuant to Section 2.25 and the Related Facilities Agreement,
no Lender may assign all or any portion of its rights and obligations under this
Agreement.   Any  assignment of rights and obligations of a  Lender  under  this
Agreement  shall  be  made  pursuant  to  an  Assignment  Agreement.   Any  such
assignment  of  rights  and  obligations of  a  Lender  hereunder  shall  become
effective  upon  the  execution and delivery to  the  Agent  of  the  Assignment
Agreement  and  the  consent of the Agent.  Promptly  following  receipt  of  an
executed  Assignment Agreement, the Agent shall send to the Borrower a  copy  of
such executed Assignment Agreement.  Promptly following receipt of such executed
Assignment  Agreement,  the  Borrower shall execute  and  deliver,  at  its  own
expense,  new  Notes  to  the  assignee and, if  applicable,  the  assignor,  in
accordance  with their respective interests, whereupon the prior  Notes  of  the
assignor  and, if applicable, the assignee, shall be cancelled and  returned  to
the Borrower.  Upon the effectiveness of any assignment pursuant to this Section
9.1(b), the assignee will become a "Lender," if not already a "Lender," for  all
purposes  of  the  Loan Documents, and the assignor shall  be  relieved  of  its
obligations  hereunder to the extent of such assignment.   If  the  assignor  no
longer holds any rights or obligations under this Agreement, such assignor shall
cease to be a "Lender" hereunder, except that its rights under Sections 2.21 and
5.17 shall not be affected.  On the last Business Day of each month during which
an  assignment has become effective pursuant to this Section 9.1(b),  the  Agent
shall  prepare  a new Exhibit IV giving effect to all such assignments  effected
during  such month and will promptly provide a copy thereof to the Borrower  and
each Lender.

      (c)  Each Lender may transfer, grant, or assign participations in all or 
any portion of its interests hereunder to its affiliates only pursuant  to  this
Section  9.1(c),  provided  that such Lender shall remain  a  "Lender"  for  all
purposes  of this Agreement and the transferee of such participation  shall  not
constitute  a  "Lender" hereunder.  In the case of any such  participation,  the
participant shall not have any rights under any Loan Document, the rights of the
participant  in respect of such participation to be against the granting  Lender
as  set forth in the agreement with such Lender creating such participation, and
all  amounts payable by the Borrower hereunder shall be determined  as  if  such
Lender had not sold such participation.

     (d)  The Lenders may furnish any information concerning the Borrower in the
possession  of  the  Lenders  from  time to  time  to  permitted  assignees  and
participants and, with the consent of the Borrower, to prospective assignees and
participants.

      (e)  Notwithstanding anything in this Section to the contrary, any  Lender
may assign and pledge all or any of its Notes or any interest therein to any 
Federal Reserve  Bank or the United States Treasury as collateral security  
pursuant  to Regulation  A  of the Board of Governors of the Federal Reserve 
System  and  any operating  circular  issued by such Federal Reserve System 
and/or  such  Federal Reserve  Bank.   No  such assignment or pledge shall 
release  the  assigning  or pledging Lender from its obligations hereunder.

      (f)  Notwithstanding any other provisions of this Section, no transfer  or
assignment  of  the  interests  or  obligations  of  any  Lender  or  grant   of
participations therein shall be permitted if such transfer, assignment, or grant
would  require the Borrower to file a registration statement with the Securities
and  Exchange Commission or any successor Governmental Authority or qualify  the
Loans under the "Blue Sky" laws of any state.

9.2     Survival   of   Representations,   Warranties,   and   Covenants.    All
representations and warranties of the Borrower and all covenants and  agreements
herein  made  shall  survive the execution and delivery of  the  Notes  and  the
Security  Instruments  and  shall remain in force and  effect  so  long  as  any
Obligation is outstanding or any Commitment exists.

9.3  Notices.  Except as to oral notices expressly authorized herein, which oral
notices shall be confirmed in writing, all notices, requests, and communications
hereunder  shall  be  in  writing  (including by  telecopy).   Unless  otherwise
expressly  provided  herein,  any  such  notice,  request,  demand,   or   other
communication shall be deemed to have been duly given or made when delivered  by
hand, or, in the case of delivery by mail, two Business Days after deposited  in
the  mail, certified mail, return receipt requested, postage prepaid, or, in the
case  of  telecopy  notice, when receipt thereof is acknowledged  orally  or  by
written  confirmation  report,  addressed to each  party  at  the  "Address  for
Notices" specified below its name on the signature pages hereof or at such other
address as shall be designated by such party in a properly given notice.

9.4   Parties in Interest.  Subject to the restrictions on changes in  corporate
structure  set forth in Section 6.8 and other applicable restrictions  contained
herein,  all  covenants and agreements herein contained by or on behalf  of  the
Borrower,  the  Agent, or the Lenders shall be binding upon  and  inure  to  the
benefit  of  the Borrower, the Agent, or the Lenders, as the case  may  be,  and
their respective legal representatives, successors, and permitted assigns.

9.5   Rights  of  Third Parties.  All provisions herein are imposed  solely  and
exclusively for the benefit of the Agent, the Lenders and the Borrower and their
successors  and  permitted  assigns.  No other  Person  shall  have  any  right,
benefit,  priority, or interest hereunder or as a result hereof or have standing
to require satisfaction of provisions hereof in accordance with their terms.

9.6   No  Waiver; Rights Cumulative.  No course of dealing on the  part  of  the
Agent or the Lenders or their officers or employees, nor any failure or delay by
the  Agent  or the Lenders with respect to exercising any of their rights  under
any  Loan  Document shall operate as a waiver thereof.  The rights of the  Agent
and the Lenders under the Loan Documents shall be cumulative and the exercise or
partial exercise of any such right shall not preclude the exercise of any  other
right.   Neither the making of the Loan nor the issuance of a Letter  of  Credit
shall constitute a waiver of any of the covenants, warranties, or conditions  of
the  Borrower contained herein.  In the event the Borrower is unable to  satisfy
any  such  covenant, warranty, or condition, neither the making of the Loan  nor
the issuance of a Letter of Credit shall have the effect of precluding the Agent
or  the  Lenders  from thereafter declaring such inability to  be  an  Event  of
Default as hereinabove provided.

9.7   Survival  Upon  Unenforceability.  In the event any one  or  more  of  the
provisions  contained  in any of the Loan Documents or in any  other  instrument
referred to herein or executed in connection with the Obligations shall, for any
reason,  be  held to be invalid, illegal, or unenforceable in any respect,  such
invalidity, illegality, or unenforceability shall not affect any other provision
of  any  Loan Document or of any other instrument referred to herein or executed
in connection with such Obligations.

9.8   Amendments;  Waivers.  Neither this Agreement nor any of  the  other  Loan
Documents  nor  any  terms  hereof  or thereof  may  be  amended,  supplemented,
modified,  or waived except in writing and in accordance with the provisions  of
this  Section.   The  Agent and the Borrower may, from time  to  time  with  the
written  consent  of  the  Required  Lenders,  enter  into  written  amendments,
supplements,  or modifications to the Loan Documents for the purpose  of  adding
any  provisions to this Agreement or the other Loan Documents or changing in any
manner  the  rights of the Lenders or the Borrower hereunder  or  thereunder  or
waiving,  on  such  terms  and  conditions as the  Agent  may  specify  in  such
instrument,  any  of  the  requirements of this  Agreement  or  the  other  Loan
Documents  or  any  Default or Event of Default and its consequences;  provided,
however,  that no such amendment, supplement, modification, or waiver shall  (a)
extend  the  time  of  payment of any Obligation, change the  rate  of  interest
thereon,  extend the Commitment Termination Date or Final Maturity,  reduce  any
fee  payable  for the account of the Lenders hereunder, release any  Collateral,
reduce  the amount of any Obligation, increase the Maximum L/C Commitment Amount
or  the  Maximum Term Loan Commitment Amount, change the Borrowing Base  or  any
provision applicable to the determination of the Borrowing Base, amend,  modify,
or  waive  any provision of this Section or Sections 3.2, 5.12, 5.17,  or  8.10,
change  the  percentage  specified in the definition  of  Required  Lenders,  or
consent  to the assignment or transfer by the Borrower of any of its  rights  or
obligations under this Agreement or the other Loan Documents, in any  such  case
without  the written consent of all Lenders, or (b) amend, modify, or waive  any
provision  of Article VIII or the rights or obligations of the Agent  (including
its  rights  and  obligations as issuer of the Letters of  Credit)  without  the
written consent of the Agent.  Any such amendment, supplement, modification,  or
waiver shall apply equally to each of the Lenders and shall be binding upon  the
Borrower,  the  Lenders,  and the Agent and all future  holders  of  the  Notes.
Notwithstanding the foregoing, the Agent may, provided that no Default or  Event
of  Default  exists,  release  Collateral the  value  of  which,  as  reasonably
determined  by  the Agent, in any fiscal year of the Borrower  does  not  exceed
$1,000,000.   In  the event of any waiver, the Borrower, the  Lenders,  and  the
Agent  shall  be  restored  to  their respective  former  positions  and  rights
hereunder  and  under  the other Loan Documents, and any  Default  or  Event  of
Default  waived  shall  be deemed to be cured and not continuing;  but  no  such
waiver  shall extend to any subsequent or other Default or Event of  Default  or
impair any right with respect thereto.

9.9   Controlling Agreement.  In the event of a conflict between the  provisions
of  this Agreement and those of any other Loan Document, the provisions of  this
Agreement shall control.

9.10  GOVERNING  LAW.   THIS AGREEMENT, THE NOTES, AND THE GUARANTIES  SHALL  BE
DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH  AND
GOVERNED  BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO  PRINCIPLES
THEREOF  RELATING  TO CONFLICTS OF LAW; PROVIDED, HOWEVER, THAT  VERNON'S  TEXAS
CIVIL  STATUTES,  ARTICLE  5069, CHAPTER 15 (WHICH REGULATES  CERTAIN  REVOLVING
CREDIT LOAN ACCOUNTS AND REVOLVING TRIPARTY ACCOUNTS) SHALL NOT APPLY.

9.11  JURISDICTION  AND  VENUE.   ALL ACTIONS OR PROCEEDINGS  WITH  RESPECT  TO,
ARISING  DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO, OR  FROM
THIS  AGREEMENT  OR  ANY  OTHER LOAN DOCUMENT MAY  BE  LITIGATED,  AT  THE  SOLE
DISCRETION AND ELECTION OF THE AGENT, IN COURTS HAVING SITUS IN HOUSTON,  HARRIS
COUNTY,  TEXAS.  THE BORROWER HEREBY SUBMITS TO THE JURISDICTION OF  ANY  LOCAL,
STATE,  OR  FEDERAL COURT LOCATED IN HOUSTON, HARRIS COUNTY, TEXAS,  AND  HEREBY
WAIVES ANY RIGHTS IT MAY HAVE TO TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF
ANY  LITIGATION BROUGHT AGAINST IT BY THE AGENT OR ANY LENDER IN ACCORDANCE WITH
THIS SECTION.

9.12  WAIVER OF RIGHTS TO JURY TRIAL.  THE BORROWER, THE AGENT, AND EACH  LENDER
HEREBY  KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY, AND  UNCONDITIONALLY
WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING, COUNTERCLAIM,
OR  OTHER  LITIGATION THAT RELATES TO OR ARISES OUT OF ANY OF THIS AGREEMENT  OR
ANY  OTHER LOAN DOCUMENT OR THE ACTS OR OMISSIONS OF THE AGENT OR ANY LENDER  IN
THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR OTHERWISE WITH RESPECT THERETO.  THE PROVISIONS OF THIS SECTION
ARE  A  MATERIAL  INDUCEMENT FOR THE AGENT AND THE LENDERS  ENTERING  INTO  THIS
AGREEMENT.

9.13  ENTIRE  AGREEMENT.   THIS  AGREEMENT AMENDS,  RESTATES  AND  REPLACES  THE
EXISTING CREDIT AGREEMENT AND CONSTITUTES THE ENTIRE AGREEMENT AMONG THE PARTIES
HERETO  WITH  RESPECT  TO  THE  SUBJECT HEREOF AND  SHALL  SUPERSEDE  ANY  PRIOR
AGREEMENT BETWEEN OR AMONG THE PARTIES HERETO, WHETHER WRITTEN OR ORAL, RELATING
TO  THE  SUBJECT  HEREOF,  INCLUDING, WITHOUT LIMITATION,  THE  EXISTING  CREDIT
AGREEMENT  AND THE CORRESPONDENCE DATED FEBRUARY 9, 1995, FROM BANK ONE  TO  THE
GUARANTOR  AND THE TERM SHEET ENCLOSED THEREWITH.  FURTHERMORE, IN THIS  REGARD,
THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS REPRESENT, COLLECTIVELY, THE
FINAL  AGREEMENT  AMONG  THE  PARTIES THERETO AND MAY  NOT  BE  CONTRADICTED  BY
EVIDENCE  OF  PRIOR,  CONTEMPORANEOUS, OR SUBSEQUENT  ORAL  AGREEMENTS  OF  SUCH
PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG SUCH PARTIES.

9.14  Counterparts.  For the convenience of the parties, this Agreement  may  be
executed  in  multiple counterparts and by different parties hereto in  separate
counterparts, each of which when so executed shall be deemed to be an  original,
and all of which shall together constitute but one and the same agreement.

           IN  WITNESS WHEREOF, this Agreement is executed as of the date  first
above written.
