     This Credit Agreement (the "Agreement") is dated as of June 29, 1995 by and
                                                                 --

a Louisiana corporation ("Newpark Environmental"), NEWPARK SHIPHOLDING TEXAS,
L.P., a Texas limited partnership ("Newpark Shipholding"), SOLOCO TEXAS, L.P., a

collectively called the "Guarantors"), HIBERNIA NATIONAL BANK ("Hibernia"), BANK
ONE TEXAS, N.A. ("Bank One"), and PREMIER BANK, NATIONAL ASSOCIATION ("Premier")
(Hibernia, Bank One and Premier are hereinafter collectively referred to
individually as "Bank" and collectively as the "Banks"), and PREMIER BANK,
NATIONAL ASSOCIATION as agent for the Banks under this Agreement (hereinafter in
such capacity referred to as the "Agent").

     Subject to the terms and conditions set forth herein, the Banks agree (a)
to extend a revolving line of credit in the maximum aggregate principal amount
of $25,000,000.00 to the Borrower and (b) to make a term loan to the Borrower in
a principal amount not to exceed $25,000,000.00. Notwithstanding any provision
herein contained to the contrary, the Banks' agreement is limited to The Ratable
Share of each Bank. The term "Ratable Share" shall mean, in the case of Premier,
40.0%; in the case of Hibernia, 30.0%; and in the case of Bank One, 30.0% .

     NOW, Therefore, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties hereto agree as follows:

     1.   REVOLVING CREDIT LOANS.

                                      -v-
<PAGE>
 
     1.01.     Revolving Line of Credit Commitment.  Subject to the terms and
conditions of this Agreement, the Banks agree to establish simultaneously
herewith in favor of the Borrower a revolving line of credit in the aggregate
principal amount of $25,000,000.00 (herein called the "Line of Credit"), and the
Borrower may request credit advances under the Line of Credit and make
borrowings and re-borrowings thereunder; provided, however, (a) direct advances
to the Borrower shall be limited to a maximum aggregate amount equal to the Line
of Credit and (b) the aggregate principal amount outstanding under the Line of
Credit shall never exceed at any time the lesser of (i) the Line of Credit
Borrowing Base plus the sum of all letter of credit allocation amounts not
included in the borrowing base or (ii) $25,000,000.00.  The letter of credit not
included in the borrowing base is the letter of credit described in Section 1.08
below.  The Line of Credit shall terminate on December 31, 1998 and no further
advances shall be made to the Borrower after such termination date.  The
commitment of each Bank to extend funds to the Borrower under the Line of Credit
is limited to each Bank's Ratable Share of $25,000,000.00.  In addition, the
Line of Credit shall be subject to a sublimit of $6,500,000.00 as provided in
Section 1.07 below.

     1.02.     Revolving Notes.  Each Bank's loans to the Borrower under the
Line of Credit shall be evidenced by a Revolving Credit Note of the Borrower, in
the principal face amount of such Bank's Ratable Share of $25,000,000.00,
payable to the order of such Bank with a maturity date of December 31, 1998, and
bearing interest payable at the rate or rates set forth in Section 3.02 below
(herein collectively called the "Revolving Notes"). Interest under each of the
Revolving Notes shall be payable monthly as therein provided. Each Bank shall
post on a schedule attached to its Revolving Note or in records relating to its
Revolving Note (i) the date and principal amount of each advance under the Line
of Credit, (ii) the rate of interest each such advance will bear, and (iii) each
payment of principal and interest thereon; provided however, that neither the
failure to make any such posting nor any inaccuracy therein shall affect the
Borrower's obligations under any Revolving Note or this Agreement. The
information set forth on such schedule shall be rebuttably presumptive evidence
of the matters described in the immediately preceding sentence.

                                      -vi-
<PAGE>
 
     1.03.     Borrowing Base.  The Line of Credit is subject to a borrowing
base (hereinafter referred to as the "Line of Credit Borrowing Base"),
calculated according to the following formula: The Line of Credit Borrowing Base
equals Eligible Receivables times eighty percent (80%), up to the maximum amount
equal to $22,500,000.00 less the sum of the face amounts of all outstanding
letters of credit issued under the Line of Credit Borrowing Base. The term
"Eligible Receivables" is herein defined as the Accounts Receivable of the
Borrower, SOLOCO, Newpark Environmental, Mallard, NEWS, SOLOCO Texas, Batson,
and SOLOCO, L.L.C. (collectively the Accounts Grantors"), aged less than ninety
(90) days from the respective invoice dates thereof less any related company
accounts, potential offsets, foreign accounts, discounts offered and finance
charges reasonably set aside by the Agent; provided, however, Eligible
Receivables shall not include (i) the entire current balance of those Accounts
Receivable not classified as Major Accounts in which twenty percent (20%) of the
aggregate of the account balances owed by a particular account debtor is aged
ninety (90) days or more from the date of invoice and (ii) that portion of any
Major Account which is aged 90 days or more from the date of invoice. Any
Accounts Receivable rendered ineligible due to the 20% rule stated in (i) above
shall render all Accounts Receivable from that particular account debtor
ineligible. The term "Accounts Receivable" is herein defined as the accounts of
Accounts Grantors now and hereafter existing which are approved by the Agent.
The term "Major Accounts" is herein defined as those accounts owed to any of the
Accounts Grantors by account debtors that are major oil and industrial companies
determined in the sole discretion of the Banks to be Major Accounts based on the
credit quality of the account debtors. The Agent will notify the Borrower in
writing of the periodic determination of Major Accounts. The Agent reserves the
right to exclude accounts that are not Eligible Receivables. If the Agent
excludes any such account or accounts, the Agent will provide the Borrower with
written notice thereof 30 days prior to exclusion of the account or accounts.
Any credit balances arising from accounts that are not Eligible Receivables will
be excluded from the Line of Credit Borrowing Base. The Banks' initial
determination of Major Accounts is attached hereto as Exhibit A.

     1.04.     Borrowing Procedure.

                                     -vii-
<PAGE>
 
     (a). Any borrowings by the Borrower under the Line of Credit to be
evidenced by the Revolving Notes shall be subject to the following procedure:
requests for advances shall be made by the Borrower to the Agent, and the total
amount of all advances shall be an amount no larger than as provided in Section
1.01 above. All information necessary in order to determine the proper amount of
each advance shall be submitted by the Borrower to the Agent together with the
borrowing base certificate in the form attached hereto as Exhibit B. The Agent
and the Banks shall have the right to verify the Borrower's computation of the
Line of Credit Borrowing Base and revise the same if the Borrower's computation
is incorrect. The Agent agrees to advise Borrower of any changes in the
Borrower's computation of the Line of Credit Borrowing Base as computed in
accordance with Exhibit B attached hereto.

     (b). Advances under a Revolving Note for a LIBOR Loan (as hereafter
defined) shall be made upon at least three (3) full business days' prior notice
(given before 10:00 a.m.) from the Borrower to the Agent, and advances under a
Revolving Note for a Prime Rate Loan (as hereafter defined) shall be made upon
at least one (1) full business day prior notice (given before 10:00 a.m.) from
the Borrower to the Agent (in each such instance, a "Notice of Borrowing"),
which Notice of Borrowing to be accomplished by the Borrower's submission of the
borrowing base certificate. Each such Notice of Borrowing shall specify (i) the
borrowing date the advance is to be paid or delivered to the Borrower (the
"Borrowing Date"), (ii) the total amount of the proposed advance (which shall be
for not less than $250,000), and (iii) whether such advance is to be as a Prime
Rate Loan or a LIBOR Loan (as such terms are defined in Section 3.01 below), and
if such advance is to be a LIBOR Loan, the Rate Period applicable thereto.

     (c). The failure of any Bank to make the advance to be made by it under the
Line of Credit shall not relieve any other Bank of its obligation, if any,
hereunder to make its advance, but no Bank shall be responsible for the failure
of any other Bank to make an advance.

     (d). Not later than 11:00 a.m. (Central time) on the Borrowing Date, each
Bank shall make its Ratable Share of such 

                                     -viii-
<PAGE>
 
Line of Credit borrowing available at the main Lafayette, Louisiana office of
the Agent in immediately available funds.

     1.05.     Mandatory Prepayments.  If the principal amount outstanding under
the Line of Credit exceeds the Line of Credit Borrowing Base, calculated as
provided in Section 1.03 herein and as verified by the Agent, then the Borrower
must either (i) provide the Agent and the Banks with an updated aging of
Accounts Receivable substantiating that the outstanding principal amount does
not exceed the Line of Credit Borrowing Base or (ii) within three (3) business
days of the occurrence of such excess make an immediate mandatory prepayment of
principal (plus accrued interest) to the Agent sufficient to reduce the
outstanding principal amount owed to an amount less than or equal to the Line of
Credit Borrowing Base.

     1.06.     Non-Use Fee.  The non-refundable annual non-use fee payable by
the Borrower to the Agent for the account of the Banks for the Line of Credit
shall be 0.50% of the unused portion of the Line of Credit, excluding issued but
unfunded letters of credit, payable quarterly.

     1.07.     Letters of Credit.  Subject to the terms and conditions of this
Agreement, Premier may (in its sole and absolute discretion) issue, upon the
Borrower's written request, letters of credit for the account of the Borrower
and/or any one or more of the Guarantors, in a maximum aggregate face amount of
$6,500,000.00.  Each requested letter of credit is subject to the limitations
provided in Section 1.01 of the Agreement and the requested letter of credit
must be necessary for the day to day operations of the Borrower and/or any one
or more of the Guarantors.  The face amount of each letter of credit issued by
Premier hereunder, regardless of the account party's identity, shall be treated
as an advance under the Line of Credit and subject, except as otherwise provided
in this Agreement, to the terms hereof.  The obligation of the Borrower to repay
any funds advanced by Premier under the letters of credit issued pursuant to
this Section 1.07 shall be evidenced by the Agent's standard form of Application
and Agreement for Irrevocable Standby Letter of Credit, a copy of which is
attached hereto as Exhibit C (herein called a "Letter of Credit Note" and
collectively the "Letter of Credit Notes").  Each Letter of Credit Note shall
constitute a partial renewal and, if applicable, an extension of 

                                      -ix-
<PAGE>
 
the Revolving Notes. The undrawn amount of any letter of credit shall not bear
interest nor shall the undrawn amount be repayable as an advance under the
Revolving Notes or a Letter of Credit Note, as the case may be, unless and until
Premier funds the letter of credit or any portion thereof. Each Letter of Credit
Note executed by the Borrower shall be payable to the order of Premier on demand
and shall bear interest, commencing on the date funds are advanced under the
Letter of Credit Note and the interest accrual shall apply only to that portion
of the principal amount of the Letter of Credit Note that is funded, and shall
be treated as a Prime Rate Loan (as hereafter defined).

     1.08.     Outstanding Letter of Credit Note.  All parties hereto
acknowledge and understand that Premier has heretofore issued a letter of credit
for the Borrower in the amount of $2,500,000.00 for the benefit of Gray &
Company, which letter of credit has not yet expired. The Borrower has heretofore
executed a Letter of Credit Note in connection with the aforesaid letter of
credit, copies of which are attached hereto as Exhibit D. The Letter of Credit
Note, as described in the preceding sentence and as the same may be renewed from
time to time by Premier to coincide with the expiration date of the
$2,500,000.00 letter of credit, shall constitute a Letter of Credit Note as
defined in Section 1.07. The face amount of the letter of credit referred to in
this Section 1.08 shall be treated as the first allocation of funds under the
Line of Credit, but not treated as an advance for purposes of calculating the
Line of Credit Borrowing Base. All parties hereto agree and understand that the
outstanding $2,500,000.00 Line of Credit Note, if funded, shall be treated as a
Prime Rate Loan (as hereafter defined), notwithstanding the terms of said Line
of Credit Note.

     1.09.     Issuance of Letters of Credit.

     (a). The Borrower shall give Premier written notice of its request for the
issuance of a letter of credit no later than 10:00 a.m. five (5) business days
prior to the date such letter of credit is requested to be issued. Such notice
shall be accompanied by a borrowing base certificate and shall specify, with
respect to such requested letter of credit, the face amount, beneficiary,
effective date of issuance, expiry date (which effective date and expiry date
shall be a business day and, with respect to the expiry date, shall be no later
than December 30, 

                                      -x-
<PAGE>
 
1998), and the purpose for which such letter of credit is to be issued.

     1.10.     Duties of Premier as Issuing Bank.  No action taken or omitted to
be taken by Premier in connection with its issuance of a letter of credit under
this Agreement shall (i) result in any liability on the part of Premier to any
other Bank, unless Premier's action or omission constitutes willful misconduct
or gross negligence; or (ii) relieve any Bank of any of its obligations to
Premier hereunder. Each Bank agrees that, prior to making any payment to a
beneficiary with respect to a drawing under a letter of credit issued by Premier
under this Agreement, that Premier shall be responsible only to confirm that
documents required by the terms of such letter of credit to be delivered as a
condition precedent to such drawing have been delivered and that the same appear
on their face to conform with the requirements thereof. Each Bank further agrees
that Premier may assume that documents appearing on their face to be the
documents required to be delivered as a condition precedent to a drawing do in
fact comply.

     1.11.     Participations.

     (a). Immediately upon the issuance by Premier of a letter of credit under
this Agreement, each Bank, other than Premier, shall be deemed to have
irrevocably and unconditionally purchased and received from Premier, without
recourse or warranty, an undivided interest and participation to the extent of
such Bank's Ratable Share in such letter of credit, including, without
limitation, all obligations of the Borrower with respect thereto and any
security therefor or guaranty pertaining thereto.

     (b). Premier shall promptly notify each other Bank, if the Borrower fails
to reimburse Premier for payments made by Premier in respect of drawings by a
beneficiary under a letter of credit. Upon such Bank's receipt of such notice,
such Bank shall unconditionally pay to the Agent, for the account of Premier, an
amount equal to such Bank's Ratable Share of the unreimbursed payment made by
Premier under the letter of credit. Such payment shall be made by such Bank in
the same currency in which the applicable letter of credit was denominated and
in same day funds on the day such Bank receives notice from the Agent that such
payment is owing, if such notice is received by such Bank prior 

                                      -xi-
<PAGE>
 
to 10:00 a.m. (Central time) on a business day; if such notice is not received
by such time, then such Bank shall remit its payment on the next business day
following the day such notice is received. Any amount payable by a Bank under
this Section 1.11 which is not paid when due pursuant to the terms hereof, shall
be payable on demand, together with interest thereon at the federal funds rate
from the date such payment was due until paid in full. The failure of any Bank
to make any payment owing by it under this Section 1.11 shall neither relieve
nor increase the obligation of any other Bank to make any payment owing by it
under this Subsection 1.11(b). The Agent shall promptly remit to Premier all
amounts received by the Agent, for the account of Premier, from each of the
other Banks pursuant to this Section 1.11.

     (c). Whenever Premier receives a payment with respect to a funded letter of
credit (including any interest thereon) for which Premier has received payments
from another Bank pursuant to Subsection 1.11(b), Premier shall promptly remit
to each Bank which has funded its participating interest therein, in the
currency and in the kind of funds so received, an amount equal to such Bank's
Ratable Share thereof.

     (d). The obligations of a Bank under Section 1.11 to make payments to the
Agent for the account of Premier with respect to a letter of credit shall be
irrevocable, not subject to any qualification or exception whatsoever, and shall
be made in accordance with the terms and conditions of this Agreement under all
circumstances including, without limitation, any of the following circumstances:

     (i)    any lack of validity or enforceability of this Agreement or any
Letter of Credit Note or security document pertaining thereto;

     (ii)   the existence of any claim, setoff, defense, or other right which
the Borrower may have at any time against a beneficiary named in a letter of
credit or any transferee of any letter of credit (or any person for whom any
such transferee may be acting), the Agent, any Bank, or any person, whether in
connection with this Agreement, any letter of credit, the transactions
contemplated herein, or any unrelated transactions 

                                     -xii-
<PAGE>
 
(including any underlying transactions between the Borrower and the beneficiary
named in any letter of credit);

     (iii)     any draft, certificate, or any other document presented under the
letter of credit proving to be forged, fraudulent, invalid, or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;

     (iv)   the surrender or impairment of any security for the performance or
observance of any of the terms of any Loan Document; or

     (v)    the occurrence of any Event of Default under this Agreement.

     1.12.     Exoneration.  As between the Borrower and the Guarantors, on the
one hand, and Premier, each other Bank, and the Agent on the other, the Borrower
and Guarantors assume all risks of the acts and omissions of, or misuse of the
letter of credit issued by Premier by the respective beneficiaries of such
letter of credit. Further, Borrower and Guarantors do hereby indemnify and agree
to hold harmless Premier, each other Bank, and the Agent from any and all
obligation, responsibility, liability and damages resulting or alleged to have
resulted from any action taken or omitted by Premier under or in connection with
the Letters of Credit or any related documents, if taken or omitted in good
faith and not constituting gross negligence or willful misconduct. In
furtherance and not in limitation of the foregoing, subject to the provisions of
the letter of credit applications, the other Banks and the Agent, in the absence
of gross negligence or intentional misconduct on its part, shall not be
responsible:

     (a). for the form, validity, sufficiency, accuracy, genuineness, or legal
effect of any document submitted by any party in connection with the application
for and issuance of a letter of credit, even if it should in fact prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent, or forged;

     (b). for the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a letter of credit or the rights
or benefits thereunder or proceeds 

                                     -xiii-
<PAGE>
 
thereof, in whole or in part, which may prove to be invalid or ineffective for
any reason;

     (c). for failure of the beneficiary of a letter of credit to comply duly
with conditions required in order to draw upon such letter of credit;

     (d). for errors, omissions, interruptions, or delays in transmission or
delivery of any messages, by mail, cable, telegraph, telex, or otherwise,
whether or not they be in cipher;

     (e). for errors in interpretation of technical terms;

     (f). for any loss or delay in the transmission or otherwise of any document
required in order to make a drawing under any letter of credit or of the
proceeds thereof;

     (g). for the misapplication by the beneficiary of such letter of credit; or

     (h). for any consequences arising from causes beyond the control of the
Agent or any Bank (including Premier) including, without limitation, any act or
omission, whether rightful or wrongful, of any present or future de jure or de
facto government or governmental authority.

     IN FURTHERANCE AND EXTENSION AND NOT IN LIMITATION OF THE SPECIFIC
PROVISIONS HEREINABOVE SET FORTH, ANY ACTION TAKEN OR OMITTED BY PREMIER UNDER
OR IN CONNECTION WITH THE LETTERS OF CREDIT OR ANY RELATED DOCUMENTS, IF TAKEN
OR OMITTED IN GOOD FAITH AND NOT CONSTITUTING GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT, SHALL NOT PUT THE AGENT, PREMIER OR ANY OTHER BANK UNDER ANY
RESULTING LIABILITY TO THE BORROWER OR RELIEVE THE BORROWER OF ANY OF ITS
OBLIGATIONS HEREUNDER TO ANY SUCH PERSON.

     1.13.     Letter of Credit Commitment Fees.  The non-refundable fee payable
by the Borrower to the Agent for the account of the Banks for issued, but
undrawn, letters of credit, as set forth above, shall be one percent (1%) per
annum of the face amount of each letter of credit issued by Premier. The said
fee shall be payable upon issuance of each letter of credit.

     2.   TERM LOAN.

                                     -xiv-
<PAGE>
 
     2.01.     Term Loan Commitment.  Subject to the terms and conditions of
this Agreement, each of the Banks agree to extend a term loan to the Borrower in
the aggregate principal amount of $25,000,000.00 (the "Term Loan"). The Term
Loan by each Bank shall be limited to each Bank's Ratable Share of
$25,000,000.00. The purpose of the Term Loan is to refinance existing
indebtedness of the Borrower, including indebtedness owed to Premier. The
indebtedness to be refinanced by the Term Loan and, as necessary, the Line of
Credit, is described in Exhibit E attached to this Agreement.

     2.02.     Term Notes.  Each Bank's Ratable Share of the Term Loan shall be
evidenced by a Term Note of the Borrower in the principal face amount of such
Bank's Ratable Share of $25,000,000.00, payable to the order of such Bank in
monthly interest installments commencing July 31, 1995 and seventeen equal
quarterly principal payments commencing March 31, 1996 and continuing each
quarter thereafter with a final eighteenth quarterly principal installment on
June 30, 2000, at which time the final quarterly principal payment shall be due,
together with all accrued and unpaid interest (singly, a "Term Note";
collectively the "Term Notes").  Notwithstanding the foregoing, the Borrower
understands and agrees that the Term Notes shall be due and payable on December
31, 1998 if the Line of Credit is not renewed on or before such date by the
Banks.  The quarterly principal payments will be in an amount necessary to
amortize each Bank's Ratable Share of $25,000,000.00 over a five year period
from the date of closing.  The interest rate applicable to the Term Notes shall
be, at the option of the Borrower, either the Prime Rate or the LIBOR Rate plus
2.25%, as such terms are defined in Section 3.01 below, subject to any
applicable rate adjustment as provided in Section 3.02(e) below.

     2.03.     Facility Fee.  The non-refundable facility fee payable by the
Borrower to the Agent for the pro rata benefit of the Banks for the Line of
Credit and the Term Loan shall be .375% of 1% of $47,500,000.00, payable by
Borrower to Agent upon execution of this Agreement.

     3.   RATES OF INTEREST; LIBOR PROVISIONS.

                                      -xv-
<PAGE>
 
     3.01 Definitions.  As used in this Agreement, the following terms shall
have the following meanings:

          "Highest Lawful Rate" shall mean, as of a particular date and with
respect to any Bank, the maximum nonusurious interest rate that may under
applicable Federal and State law then be contracted for, charged, received,
taken or reserved by such Bank in connection with its loans to the Borrower.

          "LIBOR Loan" means the outstanding principal amount of any Loan that,
during the Rate Period relating thereto, bears interest at the lesser of (i) the
LIBOR Rate plus 2.0% for Line of Credit advances or plus 2.25% for Term Loan
indebtedness applicable during such Rate Period, and (ii) the Highest Lawful
Rate in effect from time to time during such Rate Period. The said rates are
subject to change in accordance with Section 3.02(e).

          "LIBOR Rate" means with respect to each Rate Period pertaining to a
LIBOR Loan, the rate per annum equal to the rate quoted by the Bloomberg
Financial Market Service or Telerate or a recognized reporting service
acceptable to Agent in its sole discretion at approximately 9:00 a.m. Lafayette,
Louisiana time (or as soon thereafter as is practicable) on the day that is two
business days prior to the beginning of such Rate Period for Eurodollar deposit
instruments issued on the first day of such Rate Period for the number of days
comprised therein and in an amount of the LIBOR Loan to which such Rate Period
applies. The LIBOR Rate determined by Agent with respect to a particular Rate
Period shall be fixed at such rate for the duration of such Rate Period.

          "Prime Rate" shall mean a fluctuating rate per annum (based on a 360-
day daily interest factor over the number of days in an actual calendar year)
equal on any given day to the prime rate most recently announced by Bank One,
which Prime Rate shall automatically fluctuate, without special notice to the
Borrower or any other person, upward and downward as and in the amount by which
such prime rate shall fluctuate. The Prime Rate is set by Bank One as a general
reference rate of interest, taking into account such factors as Bank One may
deem appropriate. The Prime Rate is not necessarily the lowest or best rate
actually charged to any customer, and such rate may not correspond with future

                                     -xvi-
<PAGE>
 
increases or decreases in interest rates charged by other lenders or market
rates in general. Bank One and any of the Banks may make various business or
other loans at rates of interest having no relationship to the Prime Rate.
Without notice to the Borrower or any other person, the Prime Rate shall change
automatically from time to time, as determined by the Agent, subject always to
limitation to the Highest Lawful Rate.

          "Prime Rate Loan" means the outstanding principal amount of any loan
funded under the Term Notes and/or the Revolving Notes that bears interest at
the lesser of (i) the Prime Rate and (ii) the Highest Lawful Rate in effect from
time to time.

          "Rate Period" means with respect to any LIBOR Loan, the period
commencing on the date of borrowing applicable to such LIBOR Loan under Sections
1.01 and 2.01 (or with respect to the outstanding principal amount of any loan
that is to be converted to, or continued as, a LIBOR Loan, the date of such
conversion or continuation) and ending 30, 60, or 90 days thereafter, as the
Borrower may specify in a written borrowing request or the Notice of Conversion
or Continuation, as the case may be, subject, however, to the early termination
provisions set forth in Subsection 3.04(d).

     3.02.     Rates of Interest.  The indebtedness evidenced by the Revolving
Notes and the Terms Notes (collectively, the "Notes") shall bear interest on the
unpaid principal amounts thereof from time to time outstanding at a rate or
rates per annum as follows:


     (a). Advances under the Line of Credit shall bear interest prior to
maturity (by acceleration or otherwise) (i) for Prime Rate Loans at the lesser
of (A) the Prime Rate and (B) the Highest Lawful Rate in effect from time to
time, and (ii) for LIBOR Loans at the lesser of (A) the LIBOR Rate applicable
during such Rate Period plus 2%, subject to any applicable rate adjustment as
provided in Section 3.02(e) below, and (B) the Highest Lawful Rate in effect
from time to time during such Rate Period. Notwithstanding anything herein to
the contrary, there shall be no more than three set Rate Periods for any LIBOR
Loans under the Line of Credit at any one time.

                                     -xvii-
<PAGE>
 
     (b). The Term Loan indebtedness shall bear interest prior to maturity (by
acceleration or otherwise) (i) for Prime Rate Loans at the lesser of (A) the
Prime Rate and (B) the Highest Lawful Rate in effect from time to time, and (ii)
for LIBOR Loans, at the lesser of (A) the LIBOR Rate applicable during such Rate
Period plus 2.25% subject to any applicable rate adjustment as provided in
Section 3.02(e) below, and (B) the Highest Lawful Rate in effect from time to
time. Notwithstanding anything herein to the contrary, there shall be no more
than two set Rate Periods for any LIBOR Loans under the Term Loan at any one
time.

     (c). Interest on the Prime Rate Loans shall be due and payable monthly as
provided in the Notes (each a "Prime Rate Interest Payment Date") and on each
such date thereafter until the date when all principal amounts outstanding under
the Notes shall be paid in full and until the obligation of each Bank to make
such loans shall be terminated. Interest on each LIBOR Loan shall be due and
payable on each Prime Rate Interest Payment Date, and, if not a Prime Rate
Interest Payment Date, the last day of each Rate Period for such LIBOR Loan
(each a "LIBOR Interest Payment Date" and, together with each Prime Rate
Interest Payment Date, an "Interest Payment Date").

     (d). Overdue amounts of principal and interest on the Notes shall bear
interest payable on demand at a rate per annum (based on a year of 365 or 366
days and actual days lapsed) equal to the lesser of the Highest Lawful Rate or
3% per annum above the Prime Rate, but in no event to exceed the maximum rate
allowed by La. R.S. (S) 9:3509.1 if and to the extent applicable.

     (e). At each quarter end beginning December 31, 1995, 12 month cash flow
(EBITDA, as defined in Exhibit F) relative to total Funded Debt (as defined in
Exhibit F) shall be calculated to determine whether the Borrower is subject to a
rate adjustment on the LIBOR Rate which is available under the Line of Credit
and Term Loan. The first calculation will be made upon receipt of the December
31, 1995, audited financial statements of the Borrower. Subsequent quarter
calculations will be made based upon the receipt of the quarterly financial
statements and 10-Q's, except when the quarter end is the year end at which
time, the calculation will be made upon receipt of the audited financial
statements. The interest rate applicable to the Line 

                                    -xviii-
<PAGE>
 
of Credit and the Term Loan based upon the relationship of total Funded Debt to
EBITDA is shown on the attached pricing grid. In the event the Funded Debt to
EBITDA ratio changes, then at the subsequent quarter end the effective LIBOR
Rate will be adjusted with an increase or decrease as shown on the pricing grid.
The pricing or rate adjustment grid is attached hereto as Exhibit F.

     3.03.     Conversion and Continuation.

     (a). With respect to the principal amount of the indebtedness outstanding
from time to time under the Revolving Notes and/or the Term Notes, subject to
the terms and provisions of this Agreement, the Borrower shall have the option,
to (a) convert on any business day all or any part of such outstanding principal
amount maintained as Prime Rate Loan at such time to a LIBOR Loan; provided,
however, that each such LIBOR Loan shall be in a principal amount greater than
or equal to $1,000,000.00 or an integral multiple of $500,000.00 in excess
thereof, (b) convert all or any part of such outstanding principal amount
maintained as a LIBOR Loan to a Prime Rate Loan on the last day of the Rate
Period relating to such LIBOR Loan, or (c) effective as of the last day of any
Rate Period during which the outstanding principal amount of a Loan is
maintained as a LIBOR Loan, continue all or a portion of such outstanding
principal amount as a LIBOR Loan and the succeeding Rate Period of each such
continued LIBOR Loan shall commence on the last day of the Rate Period then
ended; provided, however, that each such continued LIBOR Loan shall be in a
principal amount greater than or equal to $1,000,000.00 or an integral multiple
of $500,000.00 in excess thereof. Notwithstanding anything set forth herein,
none of the outstanding principal amount of the indebtedness evidenced by the
Revolving Notes and the Term Notes shall be converted to, or continued as, a
LIBOR Loan if (y) the last day of the Rate Period relating to such LIBOR Loan
does not occur on or before December 31, 1998, or (z) an Event of Default has
occurred and is continuing.

     (b). In the event the Borrower shall elect to convert or continue all or
any part of the outstanding principal amount of indebtedness as provided in the
immediately preceding Subsection 3.03(a), the Borrower shall deliver a written
notice to the Agent (each such notice, a "Notice of Conversion or Continuation")
(y) with respect to the conversion of all or any part of such 

                                     -xix-
<PAGE>
 
indebtedness to a LIBOR Loan or the continuation of any LIBOR Loan, no later
than 10:00 a.m. Central time two business days in advance of the proposed
conversion or continuation date, and (z) with respect to the conversion of all
or any part of a LIBOR Loan to a Prime Rate Loan, no later than 10:00 a.m.
Central time on the business day immediately preceding the proposed conversion
date, specifying in each case (i) the amount of the outstanding principal amount
of each Loan that is to be converted or continued, (ii) the date of such
proposed conversion or continuation, which date shall be a business day, (iii)
whether the proposed conversion is of (A) Prime Rate Loan(s) to LIBOR Loan(s),
or (B) LIBOR Loan(s) to Prime Rate Loan(s), (iv) in the case of a conversion to,
or continuation of, a LIBOR Loan, the requested Rate Period, (v) the aggregate
principal amount of the indebtedness outstanding after giving effect to such
conversion or continuation, and (vi) that no Event of Default has occurred and
is continuing. Each Notice of Conversion or Continuation shall be irrevocable
and the Company shall be bound to convert or continue in accordance therewith.

     (c). If with respect to all or any part of the outstanding principal amount
of any LIBOR Loan the Borrower fails to timely submit a Notice of Conversion or
Continuation, such outstanding principal amount shall, effective as of the last
day of the Rate Period relating thereto, automatically and without notice of any
kind be converted to a Prime Rate Loan.

     3.04.     Provisions Relating to LIBOR Loans.

     (a). Notwithstanding anything set forth in this Agreement, the Banks shall
not be obligated to convert all or any part of the outstanding principal amount
of any indebtedness maintained as a LIBOR Loan to a Prime Rate Loan until the
last day of the Rate Period relating to such LIBOR Loan.

     (b). If the Borrower shall have requested a LIBOR Loan or requested that
all or any part of the outstanding principal amount of any indebtedness be
converted to, or continued as, a LIBOR Loan and the Agent in good faith
determines (which determination shall be conclusive) that extraordinary
circumstances make it impossible or impracticable to ascertain the applicable
LIBOR Rate for the applicable Rate Period, the Agent shall select, in such
manner as the Agent in its sole but

                                      -xx-
<PAGE>
 
reasonable discretion deems appropriate, an alternative LIBOR Rate (which shall
not in any event exceed, at any time, the Highest Lawful Rate) and such
alternative LIBOR Rate shall be the applicable LIBOR Rate for such Rate Period.

     (c). Notwithstanding anything set forth in this Agreement, if at any time
the Agent in good faith determines (which determination shall be final and
conclusive) that the introduction of, or any change in, any applicable law,
rule, regulation or treaty or any change in the interpretation, application or
administration thereof by any governmental or other regulatory authority charged
with the interpretation, application or administration thereof shall make it
unlawful for any of the Banks to maintain or fund any LIBOR Loan, the Agent
shall give notice thereof to the Borrower and effective as of the date of such
notice, and notwithstanding Subsection 3.04(a), the outstanding principal amount
of such LIBOR Loan shall be converted to a Prime Rate Loan. Within five (5)
Business Days after any Bank's written notice and demand therefor, the Borrower
shall pay to such Bank such amount or amounts (to the extent that such amount or
amounts would not be usurious under applicable Law and to the extent such amount
or amounts have not been included in the determination of the LIBOR Rate) as may
be necessary to compensate such Bank for any direct or indirect costs and losses
incurred by it under, in connection with or as a result of such conversion, but
otherwise without penalty. If notice with respect to any LIBOR Loan has been
given by the Agent pursuant to the foregoing provisions of this Subsection
3.04(c) then, unless and until the Agent notifies the Borrower that the
circumstances giving rise to such notice no longer apply, the Banks shall have
no obligation to make or convert all or any part of the outstanding principal
amount of any indebtedness into a LIBOR Loan. Any claim by the Banks for
compensation under this Subsection 3.04(c) shall be accompanied by a certificate
setting forth the computation upon which such claim is based and such
certificate shall be conclusive and binding for all purposes absent manifest
error.

     (d). In the event that any law, regulation, treaty or directive or any
change therein or in the interpretation, application or administration thereof
or compliance by any Bank with any request or directive (whether or not having
the force of law) from any central bank or other governmental authority,

                                     -xxi-
<PAGE>
 
agency or instrumentality, does or shall, as a result of, or with respect to,
any LIBOR Loan:

          (i)   subject such Bank to any tax, duty or other charge of any kind
whatsoever with respect to this Agreement, any other related loan document or
all or any part of the outstanding principal amount of any indebtedness, or
change the basis of taxation of payments to such Bank of principal, interest or
any other amount payable hereunder or under any related loan document (except
for changes in the rate of any tax presently imposed on such Bank);

          (ii)  impose, modify or hold applicable any reserve, special deposit,
compulsory loan or similar requirement against assets held by, or deposits or
other liabilities in or for the account of, advances or loans by, or other
credit extended by, or any other acquisition of funds by, any office of such
Bank; or

          (iii)     impose on such Bank any other condition;

and the result of any of the foregoing is to increase the cost to such Bank of
making, renewing or maintaining advances or extensions of credit to the Borrower
or to reduce any amount receivable from the Borrower thereunder then, in any
such case (and to the extent not already included in the calculation of the
applicable LIBOR Rate), the Borrower shall promptly pay to such Bank, within
five (5) business days after such Bank's written notice and demand therefor, any
amounts necessary to compensate such Bank for such additional cost or reduced
amount receivable.  Any claim by a Bank for compensation under this Subsection
3.04(d) shall be accompanied by a certificate setting forth the computation upon
which such claim is based and such certificate shall be conclusive and binding
for all purposes absent manifest error.  Nothing herein contained shall be
construed or so operate as to require the Borrower to pay any interest, fees,
costs or charges that shall cause the interest rate hereunder or under any other
Loan Document to exceed the Highest Lawful Rate.

     (e)  In the event any prepayment under Section 1.05 requires the Borrower
to prepay a LIBOR Loan, or any part thereof, prior to the last day of the Rate
Period relating thereto, within five (5) business days after the Agent's demand
therefor the Borrower shall pay to the Agent such amount or amounts (to the
extent that 

                                     -xxii-
<PAGE>
 
such amount or amounts would not be usurious under applicable law) as may be
necessary to compensate the Banks for any costs and losses incurred by it under,
in connection with or as a result of such prepayment. Any claim by the Agent for
compensation under this Subsection 3.04(e) shall be accompanied by a certificate
setting forth the computation upon which such claim is based and such
certificate shall be conclusive and binding for all purposes absent manifest
error.

     (f)  The Borrower may not prepay any LIBOR Loan before the last day of the
Rate Period relating thereto, except for payments required under Section 1.05.

     4.   SECURITY INTERESTS; GUARANTEES.

     4.01.     Security for Indebtedness.  The Revolving Notes, the Term Notes,

other like intangibles, and (d) unamortized loan costs and legal fees and other
like intangibles.

     8.03.     Minimum Tangible Net Worth.  The Borrower shall maintain a
minimum consolidated tangible net worth equal to the December 31, 1994 tangible
net worth of $58,796,000.00 plus 75% of the Borrower's annual net income for the
subsequent years ending December 31, 1995, December 31, 1996, and December 31,
1997. This covenant of the Agreement shall be monitored quarterly by the Agent,
and measured annually by the Agent for compliance.

     8.04.     Book Value of Fixed Assets.  The book value of the Borrower's and
the Guarantor's fixed assets, excluding specific assets subject to outside

     8.05.     Sale of Assets.  Any asset sale of $250,000.00 or more per
transaction by the Borrower or any of the Guarantors shall be applied to the
outstanding principal under the Term Notes, unless the existence of LIBOR Loans
prevents such application. In this instance, the amount will be temporarily
applied to the Revolving Notes until application of the amount to the Term Notes
is feasible. Sales in the aggregate of $2,000,000.00 a year will require Agent
approval. Any payments made and applied pursuant to this Section 8.05 shall not
have the effect of reducing or delaying the installments required in the Term
Notes.

consolidated net income plus depreciation, amortization and interest expense
(adjusted cash flow calculated on the trailing four quarters) of 1.25 times
total annual debt service (total of all principal and interest payments due in
one year).  For purposes of this calculation annual debt service will also
include the principal and interest payments necessary to repay $22,500,000
(total available to be drawn under the Line of Credit Borrowing Base) over a
five year period at the LIBOR Rate plus 2.00% (or the applicable rate in
accordance with the rate adjustment grid attached hereto as Exhibit F).  This
covenant shall be monitored and measured quarterly by the Agent for compliance.

A listing of real estate owned by the Borrower and/or any of the Guarantors is
attached hereto as Exhibit K.

     10.  LOCK BOX AGREEMENTS/CASH CONTROL ACCOUNTS.  A condition precedent to
the Bank's agreement to extend the Line of Credit and make the Term Loan is that
each of the Guarantors shall maintain a lock box for the collection of their
respective Accounts Receivable, which lock boxes have been established by the
Borrower, the Guarantors, and the Agent on behalf of the Banks. Further, the
Agent has established through its Cash Management Department a cash control
account (collectively, the "Control Accounts") for each of the Guarantors for
the deposit by the Agent of all Accounts Receivable payments made to the lock
boxes. The lock boxes and the Control Accounts are subject to (i) the terms and
provisions of the letter agreements heretofore entered into by each of the
Guarantors and the Agent, (collectively, the "Lock Box Agreements"), and (ii)
the following terms and provisions:

     (a). Access to the lock boxes shall be restricted to the Agent until such
time as the Secured Notes are paid in full and cancelled.

     (b). In no event shall the Agent or any of the Banks be liable for special
or consequential damages to the Borrower, the Guarantors or any third party
related to or arising from the performance or non-performance of lockbox
services or the breach thereof, or relating to equipment. In addition, the Agent
or any of the Banks shall not be liable in damages for lost profits or for any
claim or demand asserted against the Agent or any of the Banks by any party
other than the Guarantor asserting the claim.

     (c). The Borrower and the Guarantors are not entitled to write checks on
the Control Accounts.

     (d). On each business day the Agent representative will collect the
contents of each lock box and the same will be processed and deposited by the
Agent into the Control Accounts.

     (e). The Agent, the Banks, the Borrower, and the Guarantors agree that the
Agent's duties and responsibilities shall be limited to those set forth herein
and in the Lock Box Agreements and in performing services hereunder and
thereunder the Agent's 

                                      -xl-
<PAGE>
 
legal duty to the Borrower and the Guarantors is limited to the exercise of
ordinary care. Failure to exercise ordinary care shall be inferable or presumed
by reason of the loss of an item or other non-compliance with or non-performance
of the terms hereof without and in addition thereto, proof of the Agent's
failure to exercise such ordinary care as would legally constitute negligence on
the part of the Agent. Establishment of and substantial compliance with the
procedures attached to the Lock Box Agreements shall be deemed conclusive proof
of the Agent's exercise of ordinary care in respect to the transactions in which
the loss (whether of money, items or otherwise) or other non-performance or non-
compliance with the provisions of this Agreement occurred. In no event shall the
Agent be liable for loss or damages resulting from its failure to perform duties
pursuant to the provisions hereof if such failure is due to the occurrence of
any of the following events: any act or omission taken or omitted by any of the
Guarantors or by the Borrower, electrical, mechanical or other failure of
computer or other equipment whether used, operated or controlled by the Agent or
others; strikes or lockouts; delay or loss of items in the United States Mail or
other entity, agency or carrier delivering or transmitting items to or from the
Agent; fire or other casualty; riot or civil commotion; hurricanes, floods or
other Acts of Nature; delay in transportation, any government regulations or
interferences; or any event beyond the Agent's reasonable control.

     (f). Upon the occurrence of an Event of Default, the Agent shall be
entitled to apply all collected balances in the Control Accounts first to the
outstanding amount under the Line of Credit as evidenced by the Revolving Notes,
and then to all outstanding amounts due under the Term Notes, in such order and
manner, as agreed to by the Banks. So long as there is no Event of Default under
the Agreement, the Agent agrees to deposit all collected balances in the Control
Accounts to the said operating accounts.

     (g). The Guarantors are authorized to carry forward on their books the
uncollected balance in their respective Control Accounts at the end of each
month. The uncollected balance carried forward will be included in the aging
report furnished to the Lender provided in Section 7.07 hereof, but the
uncollected balance carried forward will not be treated by the Agent or the
Banks as an Eligible Receivable.

                                     -xli-
<PAGE>
 
     (h). Each of the Guarantors agree to immediately deposit in their
respective Control Accounts all accounts receivable payments made directly to
any of them.

     (i). The Guarantors do hereby grant to the Agent for the pro rata benefit
of the Banks a continuing security interest in the lock boxes and the Control
Accounts as security for the indebtedness due under the Secured Notes.

     (j). Upon the Borrower's payment in full of the Secured Notes and if the
Borrower is not in default hereunder, the Agent will terminate the Lock Box
Agreements.

     11.  EVENTS OF DEFAULT.  The Agent may, at its option and without notice or
demand, declare immediately due and payable the entire unpaid balance of the
Secured Notes, in principal and interest, and any and all other obligations owed
by the Borrower and/or the Guarantors to the Agent and the Banks, if any of the
following events of default (herein referred to as an "Event of Default" or an
"event of default") occur; provided, however, the occurrence of an event of
default specified in subparagraphs (a), (b), (c), and (d) below shall, at the
option of the Agent, result in the immediate and automatic acceleration of the
indebtedness due under the Secured Notes and any other indebtedness of the
Borrower to the Agent and the Banks, and any and all obligations or commitments
of the Banks shall thereby terminate unless and until the same may be reinstated
in writing by the Banks or the Agent; provided, further, that upon the
occurrence of any event of default listed in subparagraphs (e) through (k) the
Agent shall send to the Borrower, prior to an acceleration of the indebtedness,
a written notice of default and allow the Borrower thirty (30) days from date of
receipt of notice to cure or correct the default:

     (a). Nonpayment when due, whether by acceleration or otherwise, of any sum
payable under this Agreement, under any of the Secured Notes or under any other
obligation or liability of the Borrower or any of the Guarantors to the Banks
and/or the Agent, for principal, interest or otherwise.

     (b). (i)  The Borrower or any of the Guarantors shall commence any case,

is not dismissed, discharged, stayed or bonded within sixty (60) days; or (iii)
there shall be commenced against the Borrower or any of the Guarantors any case,
proceeding or other action seeking issuance of a warrant of attachment,
execution, distraint or similar process against all or any substantial part of
its assets, which results in the entry of an order for any such relief which
shall not have been vacated, discharged, stayed or bonded pending appeal within
sixty (60) days from the entry thereof; or (iv) the Borrower or any of the
Guarantors shall take any action in furtherance of, or indicating its/his
consent to, approval of, or acquiescence in, any of the acts set forth in clause
(i), (ii) or (iii) above; or (v) the Borrower or any of the Guarantors shall
generally not pay its/his debts as they become due.

in any report, financial statement or other information furnished to the Agent
and/or the Banks by the Borrower or any of the Guarantors pursuant to this
Agreement or in connection with any and all other indebtedness of the Borrower
to the Banks, proves to be false or misleading in any material respect or proves
to have omitted any material fact or contingent liability or claim against the
Borrower and/or any of the Guarantors.

     (g). Except as may be otherwise covered by (d) above, a breach of any
condition or covenant contained in this Agreement, in any of the Secured Notes,

<PAGE>
 
     Upon the occurrence of an Event of Default and the expiration of any

each of the Banks hereby appoints Premier to act as its agent hereunder and
thereunder. Each of the Banks authorizes and directs Agent to take such action
in its name and on its behalf under the terms and provisions of this Agreement
and the related loan papers, and to exercise such powers hereunder and
thereunder as are specifically delegated to or required of the Agent under the
terms and provisions of this Agreement and the related loan papers, together
with such powers as are reasonably incidental thereto. Agent is hereby expressly
authorized as Agent on behalf of itself 

                                    -xlvii-
<PAGE>
 
and the other Banks, without hereby limiting any implied authority, and, with
respect to items (g), (h), (j), and (k) below, Agent is required:

interest under the Secured Notes paid to Agent, and to distribute to each

<PAGE>
 
other information that Borrower and/or the Guarantor are required to deliver to
Agent and/or Banks pursuant to the terms of this Agreement; and

     (l). to take such other actions as may be requested by the Banks holding at
least 66 2/3% of the then aggregate unpaid principal amount of the Secured Notes
or, if no such principal amount is then outstanding, Banks having at least 66
2/3% of the aggregate Line of Credit commitment amount of $25,000,000.00 (the
"Majority Banks").

     Notwithstanding the foregoing, the Agent shall not be required to exercise
any discretion or take any action, but shall be required to act or to refrain
from acting (and, shall be fully protected in so acting or refraining from
acting) upon the instructions of the Majority Banks, and such instructions shall
be binding upon all Banks and all holders of the Secured Notes; provided,
however, that the Agent shall not be required to take any action which exposes
the Agent to personal liability or which is contrary to this Agreement or the
related loan papers or applicable law. The Agent shall not by reason of this
Agreement be deemed to be a trustee or fiduciary of any Bank or holder of the
Secured Notes.

assignment or transfer thereof signed by such payee and in form satisfactory to
the Agent; (b) may consult with legal counsel (including counsel for the

Borrower or the Guarantors or any other person or to inspect the property
(including the books and records) of the Borrower; (e) shall not be responsible
to any Bank for the due execution, legality, validity, enforceability,

notice, consent, certificate or other instrument or writing (which may be by
telegram, telecopy or telex) believed by it to be genuine and signed or sent by
the proper party or parties.

     14.03.    Rights of Agent as a Bank.  With respect to the Agent's Ratable
Share, the loans made by it and the Secured Notes issued to it, the Agent shall
have the same rights and powers under the loan papers as any other Bank and may
exercise the same as though it were not the Agent; and the term "Bank" or
"Banks" shall, unless otherwise expressly indicated, include the Agent in its
individual capacity. The Agent and any affiliates of Agent may accept deposits
from, lend money to, act as trustee under indentures of, and generally engage in
any kind of business with, the Borrower, the Guarantors, any of its/their
affiliates and any person who may do business with or own securities of the
Borrower, the Guarantors or any of its/their affiliates, all as if the Agent
were not the Agent and without any duty to account therefor to the Banks.

     14.04.    Independent Decisions; Independent Counsel.  Each Bank
acknowledges that it has, independently and without reliance upon the Agent,
Agent's counsel or any other Bank and based on such documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Bank also acknowledges that it will, independently and
without reliance upon the Agent or any other Bank and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under the loan papers.
Except for notices, reports and other documents and information expressly
required to be furnished to the Banks by the Agent under the terms of this
Agreement or related loan papers, the Agent shall have no duty or responsibility
to provide any Bank with any credit or other information concerning the affairs,

                                      -l-
<PAGE>
 
financial condition or business of the Borrower or the Guarantors (or any of
their affiliates) which may come into the possession of the Agent or any
affiliates of Agent. Each Bank acknowledges that it has had the benefit of legal
counsel of its own choice and has been afforded the opportunity to review with
its legal counsel, independently and without reliance upon the Agent or Agent's
counsel, this Agreement and each of the other loan papers including, without
limitation, each of the legal opinions heretofore or hereafter rendered to the
Banks by counsel for the Borrower and the Guarantors

     14.05.    Indemnification.  The Banks hereby indemnify the Agent (to the
extent not reimbursed by the Borrower), ratably according to the respective
amounts of their Ratable Share, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent in any way related to or arising
out of any of this Agreement or related loan papers or any action taken or
omitted by the Agent under any of the loan papers, provided that no Bank shall
be liable for any portion of any of the foregoing resulting from the Agent's
gross negligence, or willful misconduct. Without limitation of the foregoing,
each Bank agrees to reimburse the Agent (to the extent not reimbursed by the
Borrower) promptly upon demand for its Ratable Share of any out-of-pocket
expenses (including reasonable counsel fees) incurred by the Agent in connection
with the preparation, administration, or enforcement of, or legal advice in
respect of rights or responsibilities under, this Agreement or any of the loan
papers.

     14.06.    Successor Agent.  The Agent may resign at any time by giving at
least sixty (60) days prior written notice thereof to the Banks and the
Borrower. Upon any such resignation, the Majority Banks shall have the right to
appoint a successor Agent. If no successor Agent shall have been so appointed by
the Banks, within thirty (30) days after the retiring Agent's giving of notice
of resignation of the retiring Agent, the retiring Agent may, on behalf of the
Banks, appoint a successor Agent from the other Banks. Additionally, in the
event of the dissolution, insolvency, liquidation, closure (or similar event) of
the Agent, a successor agent shall be appointed by the remaining Banks (by
majority vote of the remaining Banks, with each Bank having a 

                                      -li-
<PAGE>
 
right to one vote) from among the other Banks within five (5) Business Days
following the occurrence of such event. Upon the appointment of any successor
Agent hereunder, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the former Agent,
and the former Agent shall be discharged from its duties and obligations under
this Agreement. After any resignation or replacement of an Agent hereunder, the
provisions of this section 14 shall inure to the benefit of the former Agent as
to any actions taken or omitted to be taken by it while it was Agent under any
of the loan papers.

     14.07.    Sharing of Payments, Etc.  If any Bank (or any
assignee/participant with such Bank) shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) on account of the Secured Notes held by it in excess of its Ratable
Share of payments on account of the Secured Notes held by all the Banks, such
Bank shall purchase from the other Banks such participations in the Secured
Notes held by them, and such other adjustments shall be made, as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them, provided, however, that if all or any portion of such excess
payment is thereafter recovered from or must otherwise be restored by such
purchasing Bank, such purchase from each Bank shall be rescinded and each Bank
shall repay to the purchasing Bank the purchase price to the extent of such
recovery together with an amount equal to such Bank's Ratable Share of any
interest or other amount paid or payable by the purchasing bank in respect of
the total amount so recovered. The Borrower agrees that any holder of a
participation or assignment in any of the Secured Notes may, to the fullest
extent permitted by law, exercise all its rights of payment (including the right
of set-off) with respect to such participation/assignment as fully as if such
holder of such participation/assignment were the direct creditor of the Borrower
in the amount of such participation/assignment.

     14.08.    Certain Actions Requiring Consent of Majority Banks.  
Notwithstanding anything contained herein or in any of the other loan papers to
the contrary except for the provision of Section 14.09 hereof, Agent shall not
(a) make demand for payment of any of the Secured Notes, (b) grant any waiver or
consent requested by Borrower or Guarantors, with respect to any of the 

                                     -lii-
<PAGE>
 
loan papers, (c) exercise the rights and remedies of Banks upon the occurrence
of an Event of Default including, without limitation, the purchase or
acquisition of any collateral securing the Secured Notes (except any rights of
offset and/or bankers' Lien, which rights may be exercised upon the occurrence
of an Event of Default without the concurrence of Agent or any other Bank), or
(d) amend or supplement this Agreement or any of the loan papers, without the
prior written (which may be by telecopier or tested telex) consent of the
Majority Banks.

     14.09.    Certain Actions Requiring Unanimous Consent of Banks.  
Notwithstanding anything contained herein or in any of the other loan papers to
the contrary, the Agent shall not (a) change the repayment schedule of the
Secured Notes, or the rates of interest, letter of credit fees and non-use fees
per annum to be charged to Borrower with respect to the loans, (b) change the
maturity date of the loans, (c) release any collateral securing the Secured
Notes, except for a sale of assets in an amount not to exceed $250,000.00 per
transaction, (d) discharge any of the obligations of Borrower or Guarantors
under this Agreement or any of the loan papers, (e) increase the Ratable Share
of any Bank, (f) sell or otherwise dispose of any collateral for the Secured
Notes that has been purchased by the Banks at any public or private sale of such
collateral or that has otherwise been acquired by the Banks as a result of the
exercise of the Banks' rights under the loan papers, (g) amend the provisions of
this Section 14.09, or (h) amend the definition of the term "Majority Banks,"
without the prior unanimous written (which may be by telecopies or tested telex)
consent of all Banks.

     14.10.    Voting Rights of Banks.  Unless otherwise provided for in this
Agreement, each Bank shall be entitled to vote on the matters contemplated
herein in accordance with its Ratable Share.  Failure of any one of the Banks to
honor its commitment under this Agreement shall result in the loss by such
defaulting Bank of its right to vote, and for the purposes of voting on the
matter contemplated herein, the Ratable Share of each of the non-defaulting
Banks shall be recalculated to the percentage equal to (i) the commitment of
such non-defaulting Bank divided by (ii) the aggregate commitments of all the
non-defaulting Banks.

     15.  EXPENSES AND ATTORNEY'S FEES.  The Borrower agrees to pay the out-of-
pocket disbursements, including but not limited to 

                                     -liii-
<PAGE>
 
all costs of filing, origination, recordation, incurred by the Agent and the
Banks in connection with the transactions contemplated by this Agreement and all
related guarantees, collateral and security documents and agreements, whether or
not such transactions are consummated, including the reasonable fees and
disbursements to counsel for the Agent and the Banks for services rendered
including the preparation of this Agreement and related documents.

     16.  MISCELLANEOUS.

     16.01.    Amendments, Etc.  No amendment, modification, consent,
termination, or waiver of any provision of this Agreement or any related loan
paper, nor consent to any departure by the Borrower or Guarantors from the
provisions of this Agreement or any other loan paper to which it is a party, nor
amendment, waiver or consent which affects the rights or duties of the Agent
under any of the loan papers, shall in any event be effective unless the same
shall be in writing and signed by the Agent and the Majority Banks, and then
such amendment, waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided however, that no
amendment, waiver or consent shall, unless in writing and signed by the Agent
and the Banks, accomplish any of the matters provided for in Section 14.09.

changed to such other address as shall be

to delivery with the terms of this Section 16.02.

     All such notices, requests, demands and communications shall be deemed to
have been duly given or made, (i) when delivered by hand, (ii) if by mail,
Federal Express or similar overnight delivery service, when actually received,
(iii) when telexed with answerback received, or (iv) when telecopied with
written confirmation of receipt received.

     16.03.    Survival.  All warranties, representations, and covenants made by
the Borrower and the Guarantors herein shall be considered to have been relied
upon by the Agent and the Banks and shall survive the delivery to the Agent or
the Banks of this Agreement, regardless of any investigation made by or on
behalf of the Agent or the Banks.

     16.04.    Governing Law.  THE INTERNAL LAWS OF THE STATE OF LOUISIANA AND
OF THE UNITED STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE
PARTIES HERETO AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION
OF THIS AGREEMENT AND ALL LOAN PAPERS EXECUTED IN CONNECTION HEREWITH EXCEPT TO

PAPERS.

     16.05.    Maximum Interest Rate.  The Agent and the Banks shall never be
entitled to receive, collect, or apply, as interest on the Obligation, any
amount in excess of the Highest Lawful Rate,  and, in the event the Agent or the
Banks ever receive, collect, or apply as interest, any such excess, such amount
which would be excessive interest shall be deemed a partial prepayment of
principal and treated hereunder as such; and, if the principal amount of any of
the Secured Notes is paid in full, any remaining excess shall forthwith be paid
to the Borrower.  In determining whether or not the interest paid or payable,
under any specific contingency, exceeds the Highest Lawful Rate, the Borrower,
the Guarantors, the Agent and the Banks shall, to the maximum extent permitted
under applicable law, (a) characterize any nonprincipal payment as an expense,
fee, or premium rather than as interest, (b) exclude voluntary prepayments and
the effects thereof, and (c) amortize, prorate, allocate, and spread, in equal
part, the total amount of interest throughout the entire contemplated term of
the Secured Notes so 

                                     -lvi-
<PAGE>
 
that the interest rate is uniform throughout the entire term thereof; provided
that, if any Secured Note is paid and performed in full prior to the end of the
full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Highest Lawful Rate, the Agent and Banks
shall refund to the Borrower the amount of such excess and, in such event, the
Agent and Banks shall not be subject to any penalties provided by any laws for
contracting for, charging, taking, reserving, or receiving interest in excess of
the Highest Lawful Rate.

     16.06.    Severability.  If any provision of this Agreement or any of the
related loan papers is held to be illegal, invalid, or unenforceable under
present or future laws effective during the term thereof, such provision shall
be fully severable, the Agreement or appropriate loan paper shall be construed
and enforced as if such illegal, invalid, or unenforceable provision had never
comprised a part thereof, and the remaining provisions thereof shall remain in
full force and effect and shall not be affected by the illegal, invalid, or
unenforceable provision or by its severance therefrom.  Furthermore, in lieu of
such illegal, invalid, or unenforceable provision there shall be added
automatically as a part of this Agreement such loan paper a provision as similar
in terms to such illegal, invalid, or unenforceable provision as may be possible
and be legal, valid and enforceable.

     16.07.    Accounting Principles.  All accounting terms used herein, unless
otherwise defined herein, shall be defined in accordance with generally accepted
accounting principles.  Additionally, where the character or amount of any asset
or liability or item of income or expense is required to be determined or any
consolidation or other accounting computation is required to be made for the
purposes of this Agreement, such shall be done in accordance with generally
accepted accounting principles.

which together shall constitute one and the same instrument.

acknowledge that the provisions of Section 14 of this Agreement govern the

in no way shall the provisions of Section 14 be construed to create any rights
or obligations of the Borrower or the Guarantor. Further, Borrower and
Guarantors acknowledge that, notwithstanding the provisions of Section 16.01 or
any other provision of this Agreement, the provisions of Section 14 hereof may
be amended or modified from time to time by the Banks and Agent without notice
to, or consent by, Borrower, the Guarantors, or any other party.

     16.10.    Construction.  Each party hereto acknowledges that each has had
the benefit of legal counsel of its own choice and has been afforded an
opportunity to review this Agreement and the related loan papers with its legal
counsel and that this Agreement and the related loan papers shall be construed

     16.11.    Termination.  This Agreement shall not terminate until the
Secured Notes, including any renewals or extensions thereof, and any and all
liabilities and obligations owed to the Agent and the Banks by the Borrower in
connection with the transactions contemplated by this Agreement have been fully
satisfied and the Banks shall have no further obligation to make any advances
hereunder or otherwise to Borrower. The representations and covenants contained
in this Agreement shall apply to any and all renewals, extensions, and
refinancing of any of the Secured Notes.

THE BANKS TO RESORT TO JUDICIAL ACTION TO ENFORCE ITS RIGHTS HEREUNDER, THEN THE
GUARANTORS AND THE BORROWER, HEREBY AGREE THAT TO THE EXTENT PERMITTED BY
APPLICABLE LAW ANY SUCH JUDICIAL ACTION, INCLUDING ANY OPPOSITION TO SUCH
ACTION, RECONVENTIONAL DEMANDS, AND CROSS CLAIMS, SHALL BE TRIED BEFORE A JUDGE
WITHOUT A JURY, ALL PARTIES HERETO HEREBY WAIVING THEIR RIGHT TO A JURY TRIAL.
