other Lenders (in such capacity, together with any other Person who becomes the
agent, the "AGENT") and ABN AMRO North America, Inc. as agent for ABN AMRO Bank
N.V., and The Bank of Nova Scotia, each individually as a Lender and together as
co-documentation agents for the other Lenders (in such capacity, together with
any other Person who becomes a co-documentation agent, the "CO-DOCUMENTATION
AGENTS").

               Finance Corp. has requested that the Lenders provide the Company
with a credit facility pursuant to which the Lenders will commit to make (a)
revolving credit loans of up to $40,000,000.00 including a swing line facility
not to exceed $5,000,000.00 and a letter of credit facility not to exceed

$45,000,000.00 and (d) a third term loan of up to $10,000,000.00. The proceeds
of the $85,000,000.00 term loan and the $45,000,000.00 term loan and
approximately $500,000.00 of the revolving credit loans shall be loaned by

                                      -23-

principal balance of such Swing Line Loan. The Agent shall notify each such
Lender of the amount of such Revolving Credit Loan or participation and such
Lender will transfer to the Agent for the account of the Swing Line Lender on
the next Business Day following such notice, in immediately available funds, the
amount of its Revolving Credit Loan or participation.

               (iv) If any such Lender shall not have so made its Revolving
Credit Loans or its percentage participation available to the Agent pursuant to
this SECTION 2.01(B), such Lender agrees to pay interest thereon for each day
from such date until the date such amount is paid at the lesser of (1) the
Federal Funds Effective Rate on the date payment is to be made to the Agent and
(2) the Highest Lawful Rate. Whenever, at any time after the Agent has received
from any Revolving Credit Lender such Lender's Revolving Credit Loan or
participating interest in a Swing Line Loan, the Agent receives any payment on
account thereof, the Agent will pay to such Lender its participating interest in
such amount (appropriately adjusted, in the case of interest payments, to
reflect the period of time during which such Lender's participating interest was
outstanding and funded) which payment shall be subject to repayment by such
Lender if such payment received by the Agent is required to be returned. Each
Revolving Credit Lender's obligation to make the Revolving Credit Loans or
purchase such participating interests pursuant to this SECTION 2.01(B) shall be
absolute and unconditional and shall not be affected by any circumstance,
including, without limitation, (A) any set-off, counterclaim, recoupment,
defense or other right which such Lender or any other Person may have against
the Swing Line Lender, the Agent or any other Person for any reason whatsoever;
(B) the occurrence or continuance of a Default or an Event of Default or the
termination of Revolving Credit Commitments; (C) the occurrence of any Material
Adverse Effect; (D) any breach of this Agreement by the Company or any other
Lender; or (E) any other circumstance, happening or event whatsoever, whether or
not similar to any of the foregoing. Each Swing Line Loan, once so participated
by any Revolving Credit Lender, shall cease to be a Swing Line Loan with respect
to that amount for purposes of this Agreement but shall continue to be a
Revolving Credit Loan and be evidenced by such Lender's Revolving Credit Note.

               SECTION 2.02 THE ESOP LOAN. Subject to the terms and conditions
herein set forth, each ESOP Lender agrees to make and maintain a term loan in
the amount of such Lender's ESOP Loan Commitment (the "ESOP LOAN") to the
Company. The ESOP Loan shall be fully advanced on the Effective Date, and no
ESOP Lender shall have an obligation to make any additional Advance under the
ESOP Loan after such date. Any amount repaid under the ESOP Loan may not be
reborrowed. All amounts outstanding under the ESOP Loan shall, at the option of
the Company, be made and maintained as Alternate Base Rate Advances or LIBOR
Rate Advances; provided that all Loans comprising all or a portion of the same
Advance shall when made be of the same Type.

               SECTION 2.03 THE TERM LOANS. (a) Subject to the terms and
conditions herein set forth, each Term Loan A Lender agrees to make and maintain
a term loan in the amount of such Lender's Term Loan A Commitment (the "TERM
LOAN A") to the Company. The Term Loan A shall be fully advanced on the
Effective Date, and no Term Loan A Lender shall have an obligation to

                                      -24-

make any additional Advance under the Term Loan A after such date. Any amount
repaid under the Term Loan A may not be reborrowed. All amounts outstanding
under the Term Loan A shall, at the option of the Company, be made and
maintained as Alternate Base Rate Advances or LIBOR Rate Advances; provided that
all Loans comprising all or a portion of the same Advance shall when made be of
the same Type.

               (b) Subject to the terms and conditions herein set forth, each
Term Loan B Lender agrees to make and maintain a term loan in the amount of such
Lender's Term Loan B Commitment (the "TERM LOAN B" and, together with the ESOP
Loan, Revolving Credit Loans, Swing Line Loans, Term Loan A, and any Advances
under a Letter of Credit described in ARTICLE III hereof, the "LOANS") to the
Company. The Term Loan B shall be fully advanced on the Effective Date, and no
Term Loan B Lender shall have an obligation to make any additional Advance under
the Term Loan after such date. Any amount repaid under the Term Loan B may not
be reborrowed. All amounts outstanding under the Term Loan B shall, at the
option of the Company, be made and maintained as Alternate Base Rate Advances or
LIBOR Rate Advances; provided that all Loans comprising all or a portion of the
same Advance shall when made be of the same Type.

               SECTION 2.04 NOTICE OF ADVANCE. (a) REVOLVING CREDIT LOANS.
Whenever the Company requires an Advance under the Revolving Credit Loans, it
shall give written notice thereof (a "NOTICE OF ADVANCE") (or telephonic notice

               SECTION 2.06 DISBURSEMENT OF FUNDS. (a) With respect to any
Advance to be made under any Loan other than the Swing Line Loan, no later than
1:00 p.m. (Houston, Texas time) on any Advance Date, each Lender shall make
available its pro rata portion of the amount of such Advance in U.S. dollars and

Date, the Swing Line Lender shall make available to the Company in immediately
available funds the amount of such Advance at the Company's general deposit
account maintained with the Swing Line Bank or as otherwise directed by the

               (c) Unless the Agent shall have been notified by any Lender prior
to disbursement of an Advance by the Agent that such Lender does not intend to
make available to the Agent such Lender's portion of the Advance to be made on
such date, the Agent may assume that such Lender has made such amount available
to the Agent on such Advance Date and the Agent may, in reliance upon such
assumption, make available to the Company a corresponding amount. If such
corresponding amount is not in fact made available to the Agent by such Lender
and the Agent has made available same to the Company, the Agent shall be
entitled to recover such corresponding amount on demand from such Lender. If
such Lender does not pay such corresponding amount forthwith upon the Agent's
demand therefor, the Agent shall promptly notify the Company, and the Company
shall pay such corresponding amount to the Agent within two (2) Business Days
after demand therefor. The Agent shall also be entitled to recover from such
Lender or the Company, as the case may be, interest on such corresponding amount
from the date such corresponding amount was made available by the Agent to the
Company to the date such corresponding amount is recovered by the Agent, at a
rate per annum equal to, (i) as to any Lender, the Federal Funds Effective Rate
on the date of such Advance and (ii) as to the Company, at the rate per annum
applicable to such Loan PLUS the applicable Margin. Nothing herein shall be
deemed to relieve any Lender from its obligation to fulfill its commitments
hereunder or to prejudice any rights which the Company may have against any
Lender as a result of any default by such Lender hereunder.

               SECTION 2.07 CONVERSIONS AND CONTINUANCES. Subject to the
provisions of SECTION 2.17 hereof, the Company shall have the option to convert
on any Business Day all or a portion of the outstanding principal amount of one
Type of Advance into another Type of Advance (other than Advances under the
Swing Line Loan which at all times must be maintained as Alternate Base Rate
Advances) or continue any LIBOR Advance for an additional Interest Period,
PROVIDED, no Advances may be converted into or continued as LIBOR Rate Advances
if a Default or Event of Default is in existence on the date of the conversion
or continuation. Except as provided in SECTION 2.13(B), each such conversion or
continuation shall be effected by the Company giving the Agent written notice
(each a "NOTICE OF CONVERSION") prior to 11:00 a.m. (Houston, Texas time) at
least (a) three (3)

                                      -27-

Business Days prior to the date of such conversion in the case of conversion or
continuation into or continuance as a LIBOR Rate Advance and (b) prior to 10:00
a.m. (Houston, Texas time) on the date of such conversion in the case of a
conversion into an Alternate Base Rate Advance, specifying each Advance (or
portions thereof) to be so converted or continued and, if to be converted into
or continued as a LIBOR Rate Advance, the Interest Period to be initially
applicable thereto. The Agent shall thereafter promptly notify each affected
Lender of such Notice of Conversion.

               SECTION 2.08 MANDATORY REPAYMENTS. (a) THE REVOLVING CREDIT
NOTES. All outstanding principal (and any accrued, unpaid interest) on the
Revolving Credit Notes shall be due and payable on the Revolving Credit Maturity
Date. Notwithstanding anything to the contrary contained in this Agreement or in
any other Loan Document, the aggregate outstanding principal balance of the
Revolving Credit Notes and Swing Line Loans PLUS the Letter of Credit
Obligations shall not exceed the lesser of the Borrowing Base and the Total
Revolving Credit Commitment. The Revolving Credit Lenders shall never be
required to make any Advance under the Revolving Credit Loans (or the Swing Line
Lender to make any Swing Line Loan) or issue any Letter of Credit that would
cause the aggregate outstanding principal balance of the Revolving Credit Notes
and Swing Line Loans PLUS the Letter of Credit Obligations to exceed the lesser
of the Borrowing Base and the Total Revolving Credit Commitment. If the
aggregate outstanding principal balance of the Revolving Credit Notes and Swing
Line Loans PLUS the Letter of Credit Obligations at any time exceeds the lesser
of the Borrowing Base and the Total Revolving Credit Commitment, the Company
shall immediately repay the principal of the Revolving Credit Notes in an amount
at least equal to such excess. If after giving effect to any such principal
repayment the Letter of Credit Obligations exceed the lesser of the Borrowing
Base and the Total Revolving Credit Commitment, the Company shall pay an amount
of cash equal to such excess to the Agent to be held as security for the Letter
of Credit Obligations.

               (b) THE TERM NOTES. (i) Outstanding principal on the Term Notes A
and Term Notes B shall be due and payable on each Designated Payment Date
commencing September 30, 1996 in such aggregate amounts and for such periods as

        unrelated third-party as a result of any offering (net of any expenses
        of such offering) of the common stock or other equity interest of the
        Company or any Subsidiary. All payments required under this SECTION
        2.08(B)(IV) shall be applied pro rata against Term Loan A and Term Loan
        B and, as to any payment on any of such Loans, pro rata to each
        remaining principal installment.

                      (v) In addition to the amounts required under sub clauses
        (i), (ii), (iii) and (iv) above, all outstanding principal (and any
        accrued, unpaid interest) on the Term Notes A shall be due and payable
        on the Term Loan A Maturity Date and all outstanding principal (and any
        accrued, unpaid interest) on the Term Notes B shall be due and payable
        on the Term Loan B Maturity Date.

                                      -29-

               (c) THE ESOP NOTE. Outstanding principal on the ESOP Notes shall
be due and payable on each Designated Payment Date commencing September 30,
1996, in equal installments of $500,000.00 in the aggregate for all ESOP
Lenders. All outstanding principal (and any accrued, unpaid interest) on the
ESOP Notes shall be due and payable on the ESOP Loan Maturity Date.

               (d) THE SWING LINE NOTE. All outstanding principal (and any
accrued, unpaid interest) on the Swing Line Note shall be due and payable on the
Revolving Credit Maturity Date.

               SECTION 2.09 VOLUNTARY PREPAYMENTS. The Company shall have the
right to voluntarily prepay Advances in whole or in part upon giving, in the
case of a LIBOR Rate Advance, three (3) Business Days' prior written notice to
the Agent and in the case of an Alternate Base Rate Advance, one (1) Business
Days' prior written notice to the Agent; PROVIDED that at least five (5)
Business Days' prior written notice shall be given for prepayments of Term Loan
A and Term Loan B. Such notice shall specify (a) the date and amount of
prepayment and whether the prepayment is of Term Loans or Revolving Credit
Loans; and (b) in the case of the prepayment of Term Loans, whether the Company
shall approve the election, if any, of the Term Loan B Lenders to decline their
share of any such prepayment as further provided in this SECTION 2.09. Upon
receipt of such notice, the Agent shall promptly notify each applicable Lender
of the contents thereof and of such Lender's percentage participation of such
prepayment and, in the case of any Term Loan B Lender, whether or not the
Company has elected to permit each Term Loan B Lender to, at its option, decline
its Term Loan B share of such prepayment. If any such notice is given, the
amount specified in such notice shall be due and payable on the date specified
therein and (a) no LIBOR Rate Advance may be prepaid prior to the last day of
its Interest Period unless, simultaneously therewith, the Company pays to the
Agent for the benefit of the affected Lenders, all sums necessary to compensate
such Lenders for all costs and expenses resulting from such prepayment, as
reasonably determined by such Lenders, including but not limited to those costs
described in SECTIONS 2.12(F), 2.16, and 2.17 hereof, (b) each partial
prepayment shall be made (i) in the case of a prepayment of a LIBOR Rate
Advance, in a minimum aggregate principal amount of $1,000,000.00 and integral
multiples of $100,000.00, and (ii) in the case of a prepayment of an Alternate
Base Rate Advance, in a minimum aggregate amount of $1,000,000.00 and integral
multiples of $100,000.00; and (c) each prepayment of Term Loan A, Term Loan B,
and ESOP Loan Advances pursuant to this SECTION 2.09 shall be applied to the
outstanding principal of such Advances pro rata to each remaining principal
installment.

               Notwithstanding the foregoing and subject to the Company's
approval described above, in respect of any partial prepayment of the Term Loans
(until such time as Term Loan A has been repaid in full) pursuant to this
SECTION 2.09, any Term Loan B Lender may, at its option, irrevocably decline
receipt of its Term Loan B share of any such prepayment, and, if such Lender so
declines, such share shall be applied as an additional prepayment of Term Loan A
pro rata to each remaining principal installment, as further adjusted pursuant
to balance of this SECTION 2.09. Any Term Loan B Lender may notify the Agent and
the Company of its election to decline its Term Loan B share of all such
prepayments, in which event such notice shall be effective until such Lender

                                      -30-

notifies the Agent and the Company to the contrary. Any Term Loan B Lender that
wishes to decline receipt of its share of any given prepayment pursuant to this
SECTION 2.09, shall promptly, and in any event no later than 10:00 a.m.
(Houston, Texas time) on the Business Day following receipt of its notice of
such prepayment, notify the Company and the Agent of such election. Any Term
Loan B Lender that has not provided notice pursuant to one of the two preceding
sentences prior to such 10:00 a.m. deadline shall be deemed to have elected to
accept such prepayment. The Agent shall promptly provide, to all such accepting
Term Loan B Lenders, notice of the principal amount of Term Loan B that Lenders
have elected to decline. Any such accepting Lender may, at its option,
irrevocably decline receipt of its share of any such declined share of such
prepayment (and shall indicate in such notice whether it elects to accept or
decline receipt of its share of such prepayment declined by other Lenders
pursuant to this sentence), and, if such Lender so declines, such share shall be
applied as an additional prepayment of Term Loan A in accordance with this
SECTION 2.09. Any Term Loan B Lender that wishes to decline receipt of its share
of such declined shares, shall promptly, and in any event no later than 10:00
a.m. (Houston, Texas time) on the Business Day following receipt of the notice
from the Agent regarding such declined shares, notify the Company and the Agent
of such election. Any such accepting Lender that has not provided such notice
prior to such 10:00 a.m. deadline shall be deemed to have elected to accept such
the full amount of its share of such prepayment.

               SECTION 2.10 METHOD AND PLACE OF PAYMENT/NET PAYMENTS. (a) Except
as otherwise specifically provided herein, all payments under this Agreement due
from the Company shall be made to the Agent for the benefit of the affected
Lenders, or to the Agent for the benefit of the Swing Line Lender if payment is
made under any Swing Line Loan, not later than 11:00 a.m. (Houston, Texas time)
on the date when due and shall be made in lawful money of the United States in
immediately available funds at the Payment Office.

               (b) Except with respect to withholdings of United States taxes,
as provided in SECTION 2.18, all payments (whether of principal, interest, Fees,
reimbursements or otherwise) by the Company under this Agreement shall be made
without set-off or counterclaim and shall be made free and clear of and without
deduction for any present or future tax, levy, impost or any other charge, if
any, of any nature whatsoever now or hereafter imposed by any taxing authority.
Except with respect to withholdings of United States taxes as provided in
SECTION 2.18, if the making of such payments by the Company is prohibited by law
unless such a tax, levy, impost or other charge is deducted or withheld
therefrom, the Company shall pay to the Agent, on the date of each such payment,
such additional amounts (without duplication of any amounts required to be paid
by the Company pursuant to SECTION 2.16 or SECTION 3.04) as may be necessary in
order that the net amounts received by the Lenders after such deduction or
withholding shall equal the amounts which would have been received if such
deduction or withholding were not required. The Company shall confirm that all
applicable taxes, if any, imposed on this Agreement or transactions hereunder
shall have been properly and legally paid by it to the appropriate taxing
authorities by sending official tax receipts or notarized copies of such
receipts to the Agent within thirty (30) days after payment of any applicable

                                      -31-

tax. Notwithstanding the foregoing, in no event shall the compensation payable
under this SECTION 2.10(B) (to the extent, if any, constituting interest under
applicable laws) together with all amounts constituting interest under
applicable laws and payable in connection with this Agreement, the Notes and the
other Loan Documents exceed the Highest Lawful Rate.

               SECTION 2.11 PRO RATA ADVANCES/PAYMENTS. All Advances (other than
Advances made under the Swing Line Loans) under this Agreement shall be incurred
from the affected Lenders pro rata, and all payments in respect of any Loan
(other than a payment in respect of a Swing Line Loan) from the Company to the
Agent shall be applied, on the basis of the Lenders' respective percentage
participations in the Revolving Credit Commitment, the ESOP Loan Commitment, the
Term Loan A Commitment or the Term Loan B Commitment, as the case may be. It is
understood that no Lender shall be responsible for any default by any other
Lender in its obligation to make Advances hereunder and that each Lender shall
be obligated to make the Advances provided to be made by it hereunder,
regardless of the failure of any other Lender to fulfill its commitments
hereunder.

               SECTION 2.12 INTEREST. (a) Subject to SECTION 11.08, the Company
agrees to pay interest on the total outstanding principal balance from time to
time of all Alternate Base Rate Advances from the date of each respective
Advance to maturity (whether by acceleration or otherwise) at a rate per annum
which shall at all times be equal to the lesser of (i) the Highest Lawful Rate
and (ii) the Alternate Base Rate in effect from time to time plus the applicable
Margin as such applicable Margin may change from time to time. If the Alternate
Base Rate is based on the Prime Rate, interest shall be computed on the basis of
the actual number of days elapsed over a year of 365 or 366 days, as the case
may be. If the Alternate Base Rate is based on the Federal Funds Effective Rate,
interest shall be computed on the basis of the actual number of days elapsed
over a year of 360 days.

               (b) Subject to SECTION 11.08, the Company agrees to pay interest
on the total outstanding principal balance of all LIBOR Rate Advances from time
to time from the date of each respective Advance to maturity (whether by
acceleration or otherwise) at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 360 days) which shall, during each
Interest Period applicable thereto, be equal to the lesser of (i) the Highest
Lawful Rate and (ii) the applicable LIBOR Rate for such Interest Period plus the
applicable Margin. The applicable LIBOR Rate shall be fixed for each Interest
Period and shall not change during said Interest Period but the applicable
Margin, which is added to the LIBOR Rate to determine the total interest payable
to the affected Lender, shall be adjusted, effective on the first day of each
Margin Period, whether or not said adjustment occurs at a time other than the
beginning of an Interest Period.

               (c) Subject to SECTION 11.08, overdue principal and, to the
extent permitted by law, overdue interest in respect of any Advance and all
other amounts owing hereunder shall bear interest for each day that such amounts
are overdue at a rate per annum equal to the Default Rate.

                                      -32-

               (d) Interest on each Advance shall accrue from and including the
date of such Advance to but excluding the date of any repayment thereof and
shall be payable (i) in respect of LIBOR Rate Advances (A) on the last day of
the Interest Period applicable thereto and, in the case of any Interest Period
in excess of three months, on the last day of the third month of the Interest
Period and on the last day of the Interest Period and (B) on the date of any
voluntary or mandatory repayment of Term Loan A or Term Loan B or any conversion
or continuance, (ii) in respect of Alternate Base Rate Advances (A) on each
Designated Payment Date and (B) on the date of any voluntary or mandatory
repayment and (iii) in respect of each Advance, at maturity (whether by
acceleration or otherwise) and, after maturity, on demand.

               (e) The Agent, upon determining the LIBOR Rate for any Interest
Period, shall notify the Company thereof. Each such determination shall, absent
manifest error, be final and conclusive and binding on all parties hereto. In
addition, prior to the due date for the payment of interest on any Advances set
forth in the immediately preceding paragraph, the Agent shall notify the Company
of the amount of interest due by the Company on all outstanding Advances on the
applicable due date, but any failure of the Agent to so notify the Company shall
not reduce the Company's liability for the amount owed.

               (f) Subject to SECTION 11.08, the Company shall pay to the Agent
for the account of each affected Lender, so long as the Lenders shall be
required under regulations of the Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency Liabilities,
additional interest on the unpaid principal amount of each such LIBOR Rate
Advance from the date of such Advance until such principal amount is paid in
full, at an interest rate per annum equal at all times during the Interest
Period for such Advance to the lesser of (i) the Highest Lawful Rate and (ii)
the remainder obtained by subtracting (A) the LIBOR Rate for such Interest
Period from (B) the rate obtained by dividing such LIBOR Rate referred to in
clause (A) above by that percentage equal to 100% minus the Reserve Percentage
of such Lender for such Interest Period. Such additional interest shall be
determined by such Lender as incurred and shall be payable upon demand therefor
by the Company to such Lender. Each determination by such Lender of additional
interest due under this Section 2.12(f) shall be conclusive and binding for all
purposes in the absence of manifest error.

               SECTION 2.13 INTEREST PERIODS. (a) At the time the Company gives
any Notice of Advance or Notice of Conversion in respect of the making of, or
conversion into, a LIBOR Rate Advance, the Company shall have the right to
elect, by giving the Agent on the dates and at the times specified in SECTION
2.04 or SECTION 2.07, as the case may be, notice of the interest period (each an
"INTEREST PERIOD") applicable to such LIBOR Rate Advance, which Interest Period
shall be either a one, two, three or six-month period; PROVIDED, that:

               (i) the initial Interest Period for any LIBOR Rate Advance shall
        commence on the date of such LIBOR Rate Advance (including the date of
        any conversion thereto or

                                      -33-

        continuance thereof pursuant to SECTION 2.07); each Interest Period
        occurring thereafter in respect of such LIBOR Rate Advance shall
        commence on the expiration date of the immediately preceding Interest
        Period;

               (ii) if any Interest Period relating to a LIBOR Rate Advance
        begins on a day for which there is no numerically corresponding day in
        the calendar month at the end of such Interest Period, such Interest
        Period shall end on the last Business Day of such calendar month;

               (iii) if any Interest Period would otherwise expire on a day
        which is not a Business Day, such Interest Period shall expire on the
        next succeeding Business Day, PROVIDED, that if there are no more
        Business Days in that month, the Interest Period shall expire on the
        preceding day; and

               (iv) no Interest Period for Advances shall extend beyond the
        Revolving Credit Maturity Date, Term Loan A Maturity Date, or Term Loan
        B Maturity Date or ESOP Loan Maturity Date, as the case may be.

               (b) If, upon the expiration of any Interest Period applicable to
a LIBOR Rate Advance, the Company has failed to elect a new Interest Period to
be applicable to such Advance as provided above, the Company shall be deemed to
have elected to convert such Advance into an Alternate Base Rate Advance
effective as of the expiration date of such current Interest Period.

               SECTION 2.14 INTEREST RATE NOT ASCERTAINABLE. In the event that
the Agent shall determine (which determination shall, absent manifest error, be
final, conclusive and binding upon all parties) that on any date for determining
the LIBOR Rate for any Interest Period, by reason of any changes arising after
the date of this Agreement affecting the LIBOR interbank market, adequate and
fair means do not exist for ascertaining the applicable interest rate on the
basis provided for in the definition of LIBOR Rate, then, and in any such event,
the Agent shall forthwith give notice to the Company and to the Lenders of such
determination. Until the Agent notifies the Company that the circumstances
giving rise to the suspension described herein no longer exist, the obligations
of the Lenders to make LIBOR Rate Advances shall be suspended.

               SECTION 2.15 CHANGE IN LEGALITY. (a) Notwithstanding anything to
the contrary herein contained, if any change in any law or regulation or in the
interpretation thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
or its LIBOR Lending Office to make or maintain any LIBOR Rate Advance or to
give effect to its obligations as contemplated hereby, then, by prompt written
notice to the Company, such Lender may:

                                      -34-

               (i) declare that LIBOR Rate Advances will not thereafter be made
        by such Lender hereunder, whereupon the Company shall be prohibited from
        requesting LIBOR Rate Advances from such Lender hereunder (and instead,
        any request for a LIBOR Rate Advance, as to such Lender, shall be deemed
        to be a request for an Alternate Base Rate Advance) unless such
        declaration is subsequently withdrawn; and

               (ii) require that all outstanding LIBOR Rate Advances made by
        such Lender be converted to Alternate Base Rate Advances, in which event
        (A) all such LIBOR Rate Advances made by such Lender shall be
        automatically converted to Alternate Base Rate Advances as of the
        effective date of such notice as provided in paragraph (b) below (or if
        so designated by such Lender in such notice, effective as of another
        date) and (B) all payments and prepayments of principal which would
        otherwise have been applied to repay the converted LIBOR Rate Advances
        shall instead be applied to repay the Alternate Base Rate Advances
        resulting from the conversion of such LIBOR Rate Advances.

               (b) For purposes of this SECTION 2.15, a notice to the Company by
the Agent pursuant to paragraph (a) above shall be effective on the date of
receipt thereof by the Company.

               SECTION 2.16 INCREASED COSTS, TAXES OR CAPITAL ADEQUACY
REQUIREMENTS. (a) If, after the Execution Date, the application or effectiveness
of any applicable law or regulation or compliance by any Lender with any
applicable guideline or request from any central bank or governmental authority
(whether or not having the force of law) (i) shall change the basis of taxation
of payments to such Lender of the principal of or interest on any LIBOR Rate
Advance made by such Lender or any other Fees or amounts payable hereunder
(other than taxes imposed or measured on the overall net or gross income or
revenue of such Lender or its Applicable Lending Office or franchise taxes
imposed upon it by the jurisdiction in which such Lender or its Applicable
Lending Office has an office), (ii) shall impose, modify or deem applicable any
reserve, special deposit or similar requirement with respect to any LIBOR Rate
Advance made by such Lender against assets of, deposits with or for the account
of, or credit extended by, such Lender (without duplication of any amounts paid
pursuant to SECTION 2.12(F)) or (iii) shall impose on such Lender any other
condition affecting this Agreement or any LIBOR Rate Advance made by such
Lender, and the result of any of the foregoing shall be to increase the cost to
such Lender of maintaining its Revolving Credit Commitment, Swing Line
Commitment, Term Loan A Commitment, Term Loan B Commitment or ESOP Loan
Commitment, as the case may be, or of making or maintaining any LIBOR Rate
Advance or to reduce the amount of any sum received or receivable by such Lender
hereunder (whether of principal, interest or otherwise) in respect thereof by an
amount deemed in good faith by such Lender to be material, then the Company
shall pay to such Lender such additional amount as will compensate it for such
increase or reduction upon demand.

               (b) If any Lender shall have determined in good faith that any
change after the Execution Date of any law, rule, regulation or guideline
regarding capital adequacy, or any change

                                      -35-

in the interpretation or administration thereof or compliance with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency issued after the
Execution Date has or would have the effect of reducing the rate of return on
the capital of such Lender as a consequence of, or with reference to, such
Lender's obligations hereunder to a level below that which it could have
achieved but for such change by an amount deemed by such Lender to be material,
then, from time to time, the Company shall pay to the Agent for the benefit of
such Lender such additional amount as will reasonably compensate it for such
reduction upon demand.

               (c) Each Lender will notify the Company through the Agent of any
event occurring after the date of this Agreement which will entitle it to
compensation pursuant to this SECTION 2.16, as promptly as practicable. A
certificate (i) stating that the compensation sought to be recovered pursuant to
this SECTION 2.16 is generally being charged to other similarly situated
customers and (ii) setting forth in reasonable detail the amount necessary to
compensate the Lender in question as specified in paragraph (a) or (b) above, as
the case may be, and the calculation of such amount under clause (a)(i), shall
be delivered to the Company and shall be conclusive absent manifest error. The
Company shall pay to the Agent for the account of such Lender the amount shown
as due on any such certificate upon demand. The failure on the part of any
Lender to demand increased compensation with respect to any Interest Period
shall not constitute a waiver of the right to demand compensation thereafter;
PROVIDED that with respect to events occurring prior to any notice given under
this SECTION 2.16(C), such Lenders shall only be entitled to recover
compensation for such events occurring over a period of 120 days. Upon the
request of the Company, each Lender agrees that it will use reasonable efforts
to designate a different Applicable Lending Office for the Loans due to it
affected by the matter described in SECTIONS 2.16(A) and 2.16 (B), if such
designation will avoid or reduce the liability of the Company to such Lender
under this SECTION 2.16 so long as such designation is not disadvantageous to
such Lender as determined by such Lender in its sole discretion.

               (d) Except as expressly provided in SECTION 2.16(C), failure on
the part of any Lender to demand compensation for any increased costs or
reduction in amounts received or receivable or reduction in return on capital
with respect to any Interest Period shall not constitute a waiver of such
Lender's rights to demand compensation for any increased costs or reduction in
amounts received or receivables or reduction in return on capital with respect
to such Interest Period or any other Interest Period.

               SECTION 2.17 LIBOR ADVANCE PREPAYMENT AND DEFAULT PENALTIES.
Subject to SECTION 11.08, the Company shall indemnify each Lender against any
loss or expense (other than loss of profit) which it may sustain or incur as a
consequence of (a) an advance of, or a conversion into, or a continuance of,
LIBOR Rate Advances that does not occur on the date specified therefor in a
Notice of Advance or Notice of Conversion, (b) any payment, prepayment or
conversion of a LIBOR Rate Advance required by any other provision of this
Agreement or otherwise made on a date other than the last day of the applicable
Interest Period or (c) any default in the payment or prepayment of

                                      -36-

the principal amount of any LIBOR Advance or any part thereof or interest
accrued thereon, as and when due and payable (at the due date thereof, by notice
of prepayment or otherwise). Such loss or expense shall include the amount equal
to the excess determined by each Lender of (i) its cost of obtaining the funds
for the Advance being paid, prepaid or converted or not borrowed (based on the
LIBOR Rate) for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Advance (or, in the case of a failure to borrow, the Interest Period for the
Advance which would have commenced on the date of such failure to borrow) OVER
(ii) the amount of interest (as determined by each Lender) that would be
realized in reemploying the funds so paid, prepaid or converted or not borrowed
for such period or Interest Period, as the case may be.

               The Agent, on behalf of the Lenders, will notify the Company of
any loss or expense which will entitle the Lenders to compensation pursuant to
this SECTION 2.17, as promptly as is practicable. A certificate of any Lender
setting forth any amount which it is entitled to receive pursuant to this
SECTION 2.17 shall be delivered to the Company and shall be conclusive absent
manifest error. The Company shall pay to the Agent for the account of the
Lenders the amount shown as due on any certificate upon demand. Without
prejudice to the survival of any other obligations of the Company hereunder, the
obligations of the Company under this SECTION 2.17 shall survive the termination
of this Agreement and the assignment of any of the Notes. The failure on the
part of any Lender to demand compensation with respect to this SECTION 2.17
shall not constitute a waiver of the right to demand compensation thereafter;
PROVIDED that with respect to any loss or expense incurred prior to any notice
given under this SECTION 2.17, such Lender shall only be entitled to recover
compensation for such loss or expense incurred over a period of 120 days.

               SECTION 2.18 TAX FORMS. With respect to each Lender which is
organized under the laws of a jurisdiction outside the United States, on the
date of the initial Advance hereunder, and from time to time thereafter if
requested by the Company or the Agent, each such Lender shall provide the Agent
and the Company with the forms prescribed by the Internal Revenue Service of the
United States certifying as to such Lender's status for purposes of determining
exemption from United States withholding taxes with respect to all payments to
be made to such Lender hereunder or other documents satisfactory to the Company
and the Agent indicating that all payments to be made to such Lender hereunder
are subject to such tax at a rate reduced by an applicable tax treaty. Unless
the Company and the Agent have received such forms or such documents indicating
that payments hereunder are not subject to United States withholding tax or are
subject to such tax at a rate reduced by an applicable tax treaty, the Company
or the Agent shall withhold taxes from such payments at the applicable statutory
rate in the case of payments to or for any Lender organized under the laws of a
jurisdiction outside the United States.

                                   ARTICLE III
                                LETTERS OF CREDIT

                                      -37-

               SECTION 3.01 LETTERS OF CREDIT. (a) Subject to and upon the terms
and conditions herein set forth, the Issuing Bank agrees that it will, at any
time and from time to time on or after the Effective Date and prior to the
Revolving Credit Maturity Date, following its receipt of a Letter of Credit
Request and Application for Letter of Credit, issue for the account of the
Company and in support of the obligations of the Company or any of its
Subsidiaries, one or more letters of credit (the "LETTERS OF CREDIT"), up to a
maximum amount outstanding at any one time for all Letters of Credit of
$7,500,000.00, PROVIDED that the Issuing Bank shall not issue any Letter of
Credit if at the time of such issuance: (i) Letter of Credit Obligations shall
be greater than an amount which, when added to all Advances under the Revolving
Credit Notes and the Swing Line Note then outstanding, would exceed the lesser
of the Borrowing Base and the Total Revolving Credit Commitment or (ii) the
expiry date or, in the case of any Letter of Credit containing an expiry date
that is extendible at the option of the Issuing Bank, the initial expiry date,
of such Letter of Credit is a date that is later than the Revolving Credit
Maturity Date.

               (b) The Issuing Bank shall neither renew or extend nor permit the
renewal or extension of any Letter of Credit (which renewal or extension will
not be for any period ending after the Revolving Credit Maturity Date) if any of
the conditions precedent to such renewal set forth in SECTION 5.02 are not
satisfied or waived or, after giving effect to such renewal, the expiry date of
such Letter of Credit would be a date that is later than the Revolving Credit
Maturity Date.

               SECTION 3.02 LETTER OF CREDIT REQUESTS. (a) Whenever the Company
desires that a Letter of Credit be issued for its account or that the existing
expiry date shall be extended, it shall give the Issuing Bank (with copies to be
sent to the Agent and each other Revolving Credit Lender) (i) in the case of a
Letter of Credit to be issued, at least five (5) Business Days' prior written
request therefor and (ii) in the case of the extension of the existing expiry
date of any Letter of Credit, at least five (5) Business Days prior to the date
on which the Issuing Bank must notify the beneficiary thereof that the Issuing
Bank does not intend to extend such existing expiry date. Each such request
shall be executed by the Company and shall be in the form of EXHIBIT 3.02
attached hereto (each a "LETTER OF CREDIT REQUEST") and shall be accompanied by
an Application for Letter of Credit therefor, completed to the reasonable
satisfaction of the Issuing Bank, and such other certificates, documents and
other papers and information as the Issuing Bank or the Agent may reasonably
request. Each Letter of Credit shall be denominated in U.S. dollars, shall
expire no later than the date specified in SECTION 3.01, shall not be in an
amount greater than is permitted under clause (i) of SECTION 3.01(A) and shall
be in such form as may be reasonably approved from time to time by the Issuing
Bank and the Company.

               (b) The making of each Letter of Credit Request shall be deemed
to be a representation and warranty by the Company that such Letter of Credit
may be issued in accordance with, and will not violate the requirements of this
Agreement. Unless the Issuing Bank has received notice from any Revolving Credit
Lender before it issues the respective Letter of Credit or extends

                                      -38-

the existing expiry date of a Letter of Credit that one or more of the
conditions specified in ARTICLE V are not then satisfied, or that the issuance
of such Letter of Credit would violate this Agreement, then the Issuing Bank
shall issue the requested Letter of Credit for the account of the Company in
accordance with the Issuing Bank's usual and customary practices. Upon its
issuance of any Letter of Credit or the extension of the existing expiry date of
any Letter of Credit, as the case may be, the Issuing Bank shall promptly notify
the Company and the Agent and the Agent shall notify each Revolving Credit
Lender of such issuance or extension, which notices shall be accompanied by a
copy of the Letter of Credit actually issued or a copy of any amendment
extending the existing expiry date of any Letter of Credit, as the case may be.

               SECTION 3.03 LETTER OF CREDIT PARTICIPATIONS. (a) All Letters of
Credit issued subsequent hereto shall be deemed to have been sold and
transferred by the Issuing Bank to each Revolving Credit Lender, and each
Revolving Credit Lender shall be deemed irrevocably and unconditionally to have
purchased and received from the Issuing Bank, without recourse or warranty, an
undivided interest and participation, (to the extent of such Lender's percentage
participation in the Revolving Credit Commitment) in each such Letter of Credit
(including extensions of the expiry date thereof), each substitute Letter of
Credit, each drawing made thereunder and the obligations of the Company under
this Agreement and the other Loan Documents with respect thereto, and any
security therefor or guaranty pertaining thereto.

               (b) In determining whether to pay under any Letter of Credit, the
Issuing Bank shall have no obligation relative to the Revolving Credit Lenders
other than to confirm that any documents required to be delivered under such
Letter of Credit appear to have been delivered and that they appear to comply on
their face with the requirements of such Letter of Credit.

               (c) In the event that the Issuing Bank makes any payment under
any Letter of Credit, the same shall be considered an Alternate Base Rate
Advance without further action by any Person. The Issuing Bank shall promptly
notify the Agent, which shall promptly notify each Revolving Credit Lender
thereof. Each Revolving Credit Lender shall immediately pay to the Agent for the
account of the Issuing Bank the amount of such Lender's percentage participation
of such Advance. If any Revolving Credit Lender shall not have so made its
percentage participation available to the Agent, such Lender agrees to pay
interest thereon, for each day from such date until the date such amount is paid
at the lesser of (i) the Federal Funds Effective Rate and (ii) the Highest
Lawful Rate.

               (d) The Issuing Bank shall not be liable for, and the obligations
of the Company and the Revolving Credit Lenders to make payments to the Agent
for the account of the Issuing Bank with respect to Letters of Credit shall not
be subject to, any qualification or exception whatsoever, including any of the
following circumstances:

                                      -39-

               (i) any lack of validity or enforceability of this Agreement or
          any of the other Loan Documents;

               (ii) the existence of any claim, setoff, defense or other right
        which the Company may have at any time against a beneficiary named in a
        Letter of Credit, any transferee of any Letter of Credit, the Agent, any
        Issuing Bank, any Revolving Credit Lender, or any other Person, whether
        in connection with this Agreement, any Letter of Credit, the
        transactions contemplated herein or any unrelated transactions
        (including any underlying transaction between the Company and the
        beneficiary named in any such 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 of the Loan
          Documents; or

               (v)    the occurrence of any Default or Event of Default.

               (e) The Issuing Bank shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by such Issuing Bank's gross negligence or willful
misconduct. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT SUCH ISSUING
BANK, ITS OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS (OTHER THAN WITH RESPECT TO
ANY CLAIMS BY THE ISSUING BANK AGAINST ANY SUCH OFFICER, DIRECTOR, EMPLOYEE OR
AGENT THEREOF) SHALL BE INDEMNIFIED AND HELD HARMLESS FROM, SUBJECT TO THE SAME
TYPE OF PROTECTIONS SET FORTH IN SECTION 11.05(B), ANY ACTION TAKEN OR OMITTED
BY SUCH PERSON UNDER OR IN CONNECTION WITH ANY LETTER OF CREDIT OR ANY RELATED
DRAFT OR DOCUMENT ARISING OUT OF OR RESULTING FROM SUCH PERSON'S SOLE OR
CONTRIBUTORY NEGLIGENCE, BUT NOT FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF SUCH PERSON. The Company agrees that any action taken or omitted by the
Issuing Bank under or in connection with any Letter of Credit or the related
drafts or documents, if done in accordance with the standards of care specified
in the Uniform Customs and Practice for Documentary Credits (1993 Revision),
International Chamber of Commerce, Publication No. 500 (and any subsequent
revisions thereof approved by a Congress of the International Chamber of
Commerce and adhered to by the Issuing Bank) and, to the extent not inconsistent
therewith, the Uniform Commercial Code of the State of Texas, shall not result
in any liability of the Issuing Bank to the Company.

               SECTION 3.04 INCREASED COSTS. (a) Notwithstanding any other
provision herein, but subject to SECTION 11.08, if any Revolving Credit Lender
shall have determined in good faith that any change after the Execution Date of
any law, rule, regulation or guideline or the application or effectiveness of
any applicable law or regulation or any change after the Execution Date in the

                                      -40-

interpretation or administration thereof, or compliance by any Revolving Credit
Lender (or any lending office of such Lender) with any applicable guideline or
request from any central bank or governmental authority (whether or not having
the force of law) issued after the Effective Date either (i) shall impose,
modify or make applicable any reserve, deposit, capital adequacy or similar
requirement against Letters of Credit issued, or participated in, by any
Revolving Credit Lender or (ii) shall impose on any Revolving Credit Lender any
other conditions affecting this Agreement or any Letter of Credit; and the
result of any of the foregoing is to increase the cost to any Revolving Credit
Lender of issuing, maintaining or participating in any Letter of Credit, or
reduce the amount received or receivable by any Revolving Credit Lender
hereunder with respect to Letters of Credit, by an amount deemed by such Lender
to be material, then, from time to time, the Company shall pay to the Agent for
the account of such Lender such additional amount or amounts as will reasonably
compensate such Lender for such increased cost or reduction by such Lender.

               (b) Each Revolving Credit Lender will notify the Company through
the Agent of any event occurring after the date of this Agreement which will
entitle such Lender to compensation pursuant to subsection (a) above, as
promptly as practicable. A certificate of such Lender (i) stating that the
compensation sought to be recovered pursuant to this SECTION 3.04 is generally
being charged to other similarly situated customers and (ii) setting forth in
reasonable detail such amount or amounts as shall be necessary to compensate
such Lender as specified in subsection (a) above may be delivered to the Company
(with a copy to the Agent) and shall be conclusive absent manifest error. The
Company shall pay to the Agent for the account of such Lender the amount shown
as due on any such certificate upon demand; PROVIDED that with respect to events
occurring prior to any notice given under the SECTION 3.04(B), such Lender shall
only be entitled to recover compensation for such events occurring over a period
of 120 days.

               (c) Except as expressly provided in SECTION 3.04(B), failure on
the part of any Revolving Credit Lender to demand compensation for any increased
costs or reduction in amounts received or receivable or reduction in return on
capital with respect to any Letter of Credit shall not constitute a waiver of
such Lender's rights to demand compensation for any increased costs or reduction
in amounts received or receivables or reduction in return on capital with
respect to such Letter of Credit.

               SECTION 3.05 CONFLICT BETWEEN APPLICATIONS AND AGREEMENT. To the
extent that any provision of any application related to any Letter of Credit is
inconsistent with the provisions of this Agreement, the provisions of this
Agreement shall control.

       Delivery Date occurring after December 31, 1996:

                             (A) if the ratio of Total Debt (on the last day of
              the quarter most recently ended prior to the first day of such
              Margin Period) to EBITDA is less than 3.0 to 1.0, 0.375% on the
              daily average Unutilized Commitment of each Revolving Credit
              Lender, and

                              (B) if the ratio of Total Debt (on the last day of
              the quarter most recently ended prior to the first day of such
              Margin Period) to EBITDA is equal to or greater than 3.0 to 1.0,
              or cannot be determined by the Agent because of the Company's
              failure to timely deliver its financial statements, 0.50% on the
              daily average Unutilized Commitment of each Revolving Credit
              Lender until such ratio can be so determined.

Accrued Revolving Credit Commitment Fees shall be calculated to the day
immediately preceding each Designated Payment Date and to the date the Total
Revolving Credit Commitment is terminated. Revolving Credit Commitment Fees
shall be due and payable in arrears (i) on each Designated Payment Date
commencing on the first such date following the Execution Date and (ii) on the
Revolving Credit Maturity Date.

              (b) Accrued Letter of Credit Fees shall be due and payable in
arrears (i) on each Designated Payment Date commencing on the first such date
following the Execution Date and (ii) on the Revolving Credit Maturity Date, and
shall be calculated on the basis of a 360-day year.

              (c) The Company agrees to pay to the Agent, for its own account in
connection with its duties as Agent and the arrangement and syndication of this
credit facility; for the account of Chase Securities Inc., in connection with
its arrangement and syndication of the credit facility; and

                                      -42-

for the account of each Lender as consideration for such Lender making available
the Loans, all of such fees as have been agreed to pursuant to the Agent's
Letter.

              (d) In no event shall the Fees payable under this SECTION 4.01 (to
the extent, if any, constituting interest under applicable laws) together with
all amounts constituting interest under applicable laws and payable in
connection with this Agreement, the Notes and the other Loan Documents exceed
the Highest Lawful Rate.

              SECTION 4.02 VOLUNTARY REDUCTION OF TOTAL REVOLVING CREDIT
COMMITMENT. Upon at least five (5) Business Days' prior written notice to the
Agent, the Company shall have the right, without premium or penalty, to reduce
or terminate the Unutilized Commitment in part or in whole; PROVIDED, that (a)
any such reduction shall reduce proportionately the Revolving Credit Commitment
of each of the Revolving Credit Lenders and (b) any partial reduction shall be
in the amount of $5,000,000.00 or integral multiples thereof.

              SECTION 4.03 MANDATORY REDUCTION OF TOTAL REVOLVING CREDIT
COMMITMENT. The Revolving Credit Commitments, if not sooner terminated, shall

corporate power and authority to execute, deliver and perform its obligations
hereunder and under the other Loan Documents to which it is a party and all such
action has been duly authorized by all necessary corporate proceedings on its

business after the Effective Date.

               SECTION 6.04 CONFLICTING OR ADVERSE AGREEMENTS OR RESTRICTIONS.
No Loan Party is a party to any contract or agreement or subject to any
restriction which would reasonably be expected to have a Material Adverse
Effect. As of the Execution Date, all agreements (other than this Agreement and
the other Loan Documents and the agreements evidencing the Subordinated Debt) of
the Company and its Subsidiaries relating to the lending of money or the
issuance of letters of credit to or for the account of any party are described
hereto on SCHEDULE 6.04. Neither the execution nor delivery of the Loan
Documents nor compliance with the terms and provisions hereof or thereof will be
contrary to the provisions of, or constitute a default under (a) the charter or
bylaws of any Loan Party or (b) any applicable law or any applicable regulation,
order, writ, injunction or decree of any court or governmental instrumentality
or (c) any material agreement to which any Loan Party is a party or by which it
is bound or to which it is subject.

               SECTION 6.05 TITLE TO ASSETS; LICENSES AND PERMITS. The Company
has good title to all personal property and good and indefeasible title to or a
subsisting leasehold interest in, all realty as reflected as of the Effective
Date on its books and records as being owned or leased by it

                                      -48-

All of such assets are being maintained by the appropriate Person in good
working condition in accordance with industry standards. All of the real
property owned or leased by the Company as of the Effective Date is set forth on
SCHEDULE 6.05 hereto, with the applicable owner or lessee, location and real
property interest identified thereon. True, correct and complete copies of (i)
each such real property lease (and all amendments thereto) of which the Company
has possession or knowledge have been delivered to the Agent and (ii) all real
property leases (and amendments thereto) executed after the Effective Date have
been delivered to the Agent. The items of real and personal property owned by or
leased to and used by the Company constitute all of the material assets used in
the conduct of its business as presently conducted after giving effect to the
Merger, and neither this Agreement nor any other Loan Document, nor any
transaction contemplated under any such agreement, will affect any right, title
or interest of the Company in and to any of such assets in a manner that would
have or is reasonably likely to have a Material Adverse Effect. To the knowledge
of the Company there are no actual, threatened or alleged defaults of a material
nature with respect to any leases of real property under which the Company is
bound after giving effect to the Merger. After giving effect to the Merger, the
Company is current and in good standing with respect to all governmental
approvals, permits, certificates, licenses, consents and franchises necessary to
continue to conduct its business and to own or lease and operate its properties
as heretofore conducted, owned, leased or operated except where any such failure
to maintain approvals, permits, certificates, licenses, consents and franchises
would not have a Material Adverse Effect.

               SECTION 6.06 LITIGATION. Except as shown on SCHEDULE 6.06 as of
the Effective Date, no proceedings before any court or governmental agency or
department are pending against any Loan Party and, to the knowledge of the
Company, none of same affect any Loan Party or have been threatened. At any time
after the Effective Date, no proceedings against or affecting any Loan Party are
pending or, to the knowledge of the Company, threatened before any court or
governmental agency or department which could reasonably be expected to have a
Material Adverse Effect.

with GAAP consistently applied and present fairly, in all material respects, the
financial condition of TOC, its Subsidiaries and Affiliates as of the dates
thereof. Since May 31, 1995, there has not occurred any event which would
reasonably be expected have a Material Adverse Effect.

               SECTION 6.08 NO DEFAULTS. The Company and its Subsidiaries are
not in default (a) under any material provisions of any instrument evidencing
any Indebtedness or of any agreement relating thereto in such manner as to cause
a Material Adverse Effect or (b) in any respect under or in violation of any
order, writ, injunction or decree of any court or governmental instrumentality,
in

                                      -49-

such manner as to cause a Material Adverse Effect or (c) under any provision of
any Material Contract, which default would reasonably be expected to have a
Material Adverse Effect.

liability by the Company or any ERISA Affiliate, or in the imposition of any
Lien on any of the rights, properties or assets of the Company or any ERISA
Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty

with Financial Accounting Standards Board Statement No. 106, without regard to

which the Company and its Subsidiaries have agreed to, assumed or retained, or
by which the Company and its Subsidiaries are adversely affected, by contract or
otherwise, except such obligations, undertakings or liabilities as would not

              SECTION 6.13 PURPOSE OF LOANS. (a) The proceeds of the Advances of
the Term Loan A, the Term Loan B and approximately $500,000.00 of the Revolving

transaction expenses incurred in connection with the Acquisition, and (ii) by
the

                                      -51-

              (b) None of the proceeds of any Advance will be used directly or
indirectly for the purpose of purchasing or carrying any "margin stock" within
the meaning of Regulation U (herein called "margin stock") or for the purpose of
reducing or retiring any indebtedness which was originally incurred to purchase
or carry margin stock, or for any other purpose which might constitute this
transaction as a "purpose credit" within the meaning of Regulation U. Neither
the Company nor any agent acting on its behalf has taken or will take any action
which might cause this Agreement or any other Loan Document to violate, or
involve the Lenders in a violation of, Regulation G, Regulation U, Regulation X,
or any other regulation of the Board of Governors or to violate the Exchange
Act.

any Lender by or on behalf of the Company or any of its Subsidiaries in
connection with this Agreement or any transaction contemplated hereby, taken as
a whole, contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein and
therein not misleading. The financial information with respect to the Company's

stated therein, which assumptions were believed by the Company to be reasonable

carried on) and in such amounts (and with co-insurance and deductibles) as such
insurance is usually carried by

                                      -52-

businesses and similarly situated, but in any event, with respect to
improvements to real property and tangible personal property (assuming the
subject improvements are in fact replaced or restored), in amounts in excess of

businesses and the ownership of their respective properties: all statutes,

and will cause its Subsidiaries to pay and discharge all material taxes,
assessments and governmental charges or levies imposed upon them or upon their
respective incomes or profits, or upon any properties belonging to any of them,

                                      -57-

rights, franchise agreements, business contracts, patents, trademarks, licenses
and Material Contracts as may be required so that the business carried on in

with and will cause its Subsidiaries to comply with all applicable statutes
(except as to ERISA and Environmental Laws, only to the extent required under
Sections 6.11 and 6.12, respectively), regulations and orders of, and all
applicable restrictions imposed by, all governmental bodies, domestic or
foreign, except for any failure to so comply that would not reasonably be

              SECTION 9.02 PRIMARY REMEDIES. In any such event, and at any time
after the occurrence of any of the above described events, the Agent shall, if
requested by the Majority Lenders, by written notice to the Company (a "NOTICE
OF DEFAULT") take any or all of the following actions (without prejudice to the
rights of any Lender to enforce any other rights it may have against

                                      -68-

the Company, PROVIDED that, if an Event of Default specified in SECTION 9.01(F)
or SECTION 9.01(G) shall occur, the following shall occur automatically without
the giving of any Notice of Default): (a) declare the Total Commitment
terminated, whereupon the Total Commitment shall forthwith terminate immediately
and any Revolving Credit Commitment Fee shall forthwith become due and payable
without any other notice of any kind; (b) declare the principal of and any
accrued and unpaid interest in respect of all Advances, and all obligations
owing hereunder, to be, whereupon the same shall become, forthwith due and

declaration or notice of acceleration or any other notice of any kind, all of
which are hereby waived by the Company; and (c) exercise any rights or remedies
under any of the Loan Documents.

              SECTION 9.03 OTHER REMEDIES. Upon the occurrence and during the
continuance of any Event of Default, the Agent may proceed to protect and
enforce its and the Lenders' rights, either by suit in equity or by action at
law or both, whether for the specific performance of any covenant or agreement
contained in this Agreement or in any other Loan Document or in aid of the
exercise of any power granted in this Agreement or in any other Loan Document;
or may proceed to enforce the payment of all amounts owing to the Lenders under
the Loan Documents and any accrued and unpaid interest thereon in the manner set
forth herein or therein; it being intended that no remedy conferred herein or in
any of the other Loan Documents is to be exclusive of any other remedy, and each
and every remedy contained herein or in any other Loan Document shall be
cumulative and shall be in addition to every other remedy given hereunder and
under the other Loan Documents or now or hereafter existing at law or in equity
or by statute or otherwise.

                                    ARTICLE X
                                    THE AGENT

              SECTION 10.01 AUTHORIZATION AND ACTION. Each Lender hereby
irrevocably appoints and authorizes the Agent to act on its behalf and to
exercise such powers under this Agreement and the other Loan Documents as are
specifically delegated to or required of the Agent by the terms hereof, together
with such powers as are reasonably incidental thereto. The Agent may perform any
of its duties hereunder by or through its agents and employees. The duties of
the Agent shall be mechanical and administrative in nature; the Agent shall not
have by reason of this Agreement or any other Loan Document a fiduciary
relationship in respect of any Lender; and nothing in this Agreement or any
other Loan Document, expressed or implied, is intended to, or shall be so
construed as to, impose upon the Agent any obligations in respect of this
Agreement or any other Loan Document except as expressly set forth herein or
therein. As to any matters not expressly provided for by this Agreement, the
Notes or the other Loan Documents (including enforcement or collection of the
Notes), 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 Lenders, and such instructions shall be

                                      -69-

binding upon the Lenders and all holders of Notes and the Obligations; PROVIDED,
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 applicable law.

              SECTION 10.02 AGENT'S RELIANCE. (a) Neither the Agent nor any of
its directors, officers, agents or employees shall be liable to the Lenders for
any action taken or omitted to be taken by it or them under or in connection
with this Agreement, the Notes or any of the other Loan Documents (i) with the
consent or at the request of the Majority Lenders or (ii) in the absence of its
or their own gross negligence or willful misconduct (IT BEING THE EXPRESS
INTENTION OF THE PARTIES HERETO THAT THE AGENT AND ITS DIRECTORS, OFFICERS,
AGENTS AND EMPLOYEES SHALL HAVE NO LIABILITY FOR ACTIONS AND OMISSIONS UNDER
THIS SECTION 10.02 RESULTING FROM THEIR SOLE ORDINARY OR CONTRIBUTORY
NEGLIGENCE).

              (b) Without limitation of the generality of the foregoing, the
Agent: (i) may treat the payee of each Note and the Obligations as the holder
thereof until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent; (ii) may
consult with legal counsel (including counsel for the Company), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts; (iii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations made in or in connection with this
Agreement, any Note or any other Loan Document; (iv) except as otherwise
expressly provided herein, shall not have any duty to ascertain or to inquire as
to the performance or observance of any of the terms, covenants or conditions of
this Agreement, any Note or any other Loan Document or to inspect the property
(including the books and records) of the Company; (v) shall not be responsible
to any Lender for the due execution, legality, validity, enforceability,
collectibility, genuineness, sufficiency or value of this Agreement, any Note,
any other Loan Document or any other instrument or document furnished pursuant
hereto or thereto; (vi) shall not be responsible to any Lender for the
perfection or priority of any Lien securing the Obligations; and (vii) shall
incur no liability under or in respect of this Agreement, any Note or any other
Loan Document by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telegram, telecopier, cable or telex)
reasonably believed by it to be genuine and signed or sent by the proper party
or parties.

              SECTION 10.03 AGENT AND AFFILIATES; TCB AND AFFILIATES. Without
limiting the right of any other Lender to engage in any business transactions
with the Company or any of its Affiliates, with respect to their commitments,
the Loans made by them and the Notes issued to them, TCB and each other Lender
who may become the Agent shall have the same rights and powers under this
Agreement and its Notes as any other Lender and may exercise the same as though
it was not the Agent; and the term "Lender" or "Lenders" shall, unless otherwise
expressly indicated, include TCB and any such other Lender, in their individual
capacities. TCB, each other Person who becomes the Agent and their respective
Affiliates may be engaged in, or may hereafter engage in, one or more

                                      -70-

loans, letters of credit, leasings or other financing activity not the subject
of this Agreement (collectively, the "OTHER FINANCINGS") with the Company or any
of its Affiliates, or may act as trustee on behalf of, or depositary for, or
otherwise engage in other business transactions with the Company or any of its
Affiliates (all Other Financings and other such business transactions being
collectively, the "OTHER ACTIVITIES") with no responsibility to account therefor
to the Lenders. Without limiting the rights and remedies of the Lenders
specifically set forth herein, no other Lender by virtue of being a Lender
hereunder shall have any interest in (a) any Other Activities, (b) any present
or future guaranty by or for the account of the Company not contemplated or
included herein, (c) any present or future offset exercised by the Agent in
respect of any such Other Activities, (d) any present or future property taken
as security for any such Other Activities or (e) any property now or hereafter
in the possession or control of the Agent which may be or become security for
the obligations of the Company hereunder and under the Notes by reason of the
general description of indebtedness secured, or of property contained in any
other agreements, documents or instruments related to such Other Activities;
PROVIDED, HOWEVER, that if any payment in respect of such guaranties or such
property or the proceeds thereof shall be applied to reduction of the
Obligations evidenced hereunder and by the Notes, then each Lender shall be
entitled to share in such application according to its pro rata portion of such
Obligations.

              SECTION 10.04 LENDER CREDIT DECISION. Each Lender acknowledges and
agrees that it has, independently and without reliance upon the Agent or any
other Lender and based on the financial statements referred to in SECTION 7.01
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges and agrees 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 decisions in
taking or not taking action under this Agreement and the other Loan Documents.

              SECTION 10.05 AGENT'S INDEMNITY. (a) The Agent shall not be
required, insofar as the Lenders are concerned, to take any action hereunder or
to prosecute or defend any suit in respect of this Agreement, the Notes or any
other Loan Document unless indemnified to the Agent's satisfaction by the
Lenders against loss, cost, liability and expense. If any indemnity furnished to
the Agent shall become impaired, it may call for additional indemnity and cease
to do the acts indemnified against until such additional indemnity is given. In
addition, the Lenders agree to indemnify the Agent (to the extent not reimbursed
by the Company), ratably according to the respective aggregate principal amounts
of the Notes then held by each of them (or if no Notes are at the time
outstanding, ratably according to the respective amounts of the Total
Commitment), 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 relating to or arising out of this
Agreement or any action taken or omitted by the Agent (in such capacity) under
this Agreement, the Notes and the other Loan Documents. Without limitation of
the foregoing, each Lender agrees to reimburse the Agent

                                      -71-

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, execution, administration, or enforcement of, or legal advice in
respect of rights or responsibilities under, this Agreement, the Notes and the
other Loan Documents to the extent that the Agent is not reimbursed for such
expenses by the Company. The provisions of this SECTION 10.05(A) shall survive
the termination of this Agreement, the payment of the Obligations and/or the
assignment of any of the Notes.

              (b) Notwithstanding the foregoing, no Lender shall be liable under
this SECTION 10.05(B) to the Agent for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements due to the Agent resulting from the Agent's gross
negligence or willful misconduct. EACH LENDER AGREES, HOWEVER, THAT IT EXPRESSLY
INTENDS, UNDER THIS SECTION 10.05(B), TO INDEMNIFY THE AGENT RATABLY AS
AFORESAID FOR ALL SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS ARISING OUT OF OR
RESULTING FROM THE AGENT'S SOLE ORDINARY OR CONTRIBUTORY NEGLIGENCE.

              SECTION 10.06 SUCCESSOR AGENT. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Company and may be removed
as Agent under this Agreement, the Notes and the other Loan Documents at any
time with or without cause by the Majority Lenders. Upon any such resignation or
removal, the Majority Lenders shall have the right to appoint a successor Agent,
subject to the approval of the Company, if no Event of Default has occurred and
is continuing, (which approval will not be unreasonably withheld). If no
successor Agent shall have been so appointed by the Majority Lenders, and shall
have accepted such appointment, within 30 calendar days after the retiring
Agent's giving of notice of resignation or the Majority Lenders' removal of the
retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or of any state thereof and having a combined
capital and surplus of at least $50,000,000. Upon the acceptance of any
appointment as Agent hereunder and under the Notes and the other Loan Documents
by a successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations under
this Agreement, the Notes and the other Loan Documents. After any retiring
Agent's resignation or removal as Agent hereunder and under the Notes and the
other Loan Documents, the provisions of this ARTICLE X shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement, the Notes and the other Loan Documents.

              SECTION 10.07 NOTICE OF DEFAULT. The Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent shall have received notice from a Lender or the
Company referring to this Agreement, describing such Default or Event of Default
and stating that such notice is a "notice of default." If the Agent receives
such notice, the Agent shall give notice thereof to the Lenders; PROVIDED,
HOWEVER, if such notice is

                                      -72-

received from a Lender, the Agent also shall give notice thereof to the Company.
The Agent shall be entitled to take action or refrain from taking action with
respect to such Default or Event of Default as provided in SECTION 10.01 and
SECTION 10.02.

                                   ARTICLE XI
                                  MISCELLANEOUS

              SECTION 11.01 AMENDMENTS. No amendment or waiver of any provision
of this Agreement, any Note or any other Loan Document, nor consent to any
departure by the Company herefrom or therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Company, as to amendments,
and by the Majority Lenders in all cases, and then, in any case, such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given PROVIDED, no such amendment shall be effective unless
signed by all of the Lenders if it attempts to: (a) change the definition of
"COMMITMENT," "DESIGNATED PAYMENT DATE," "MAJORITY LENDERS," "MARGIN,"
"REVOLVING CREDIT COMMITMENT," "REVOLVING CREDIT MATURITY DATE," "TERM LOAN A
COMMITMENT," "TERM A LOAN MATURITY DATE," "TERM LOAN B COMMITMENT," "TERM LOAN B
MATURITY DATE," "ESOP LOAN COMMITMENT," "ESOP LOAN MATURITY DATE," "TOTAL
COMMITMENT," or "TOTAL REVOLVING CREDIT COMMITMENT"; (b) reduce or increase the
amount or alter the terms of the Commitment of any Lender or subject any Lender
to additional obligations; (c) modify this SECTION 11.01; (d) waive any Default
under SECTION 9.01(A); (e) in any manner change the amount of, or any date fixed
for, any payment of principal or interest on the Notes or any Fee or the
reimbursement obligations of the Company under any Letter of Credit; (f) modify
or waive the mandatory prepayment requirements set forth in Section 2.08 hereof
or the allocation of such prepayments to the Lenders; or (g) except as expressly
permitted hereby, release any collateral pledged as security for the Obligations
or release any Guarantor from its obligations under the Guaranty.

              SECTION 11.02 NOTICES. Except with respect to telephone

Lender or the Agent to exercise, and no delay in exercising, any right
hereunder, under any Note or under any other Loan Document shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right, or
any abandonment or discontinuance of any steps to enforce such right, preclude
any other or further exercise thereof or the exercise of any other right. No
notice to or demand on the Company in any case shall entitle the Company to any
other or further notice or demand in similar or other circumstances. The
remedies herein are cumulative and not exclusive of any other remedies provided
by law, at equity or in any other agreement.

                                      -74-

              SECTION 11.04 COSTS, EXPENSES AND TAXES. The Company agrees to pay
on demand: (a) all reasonable out-of-pocket costs and expenses of the Agent in
connection with the preparation, execution and delivery of this Agreement, the
Notes, the other Loan Documents and the other documents to be delivered
hereunder, including the reasonable fees and out-of-pocket expenses of counsel
for the Agent with respect thereto and with respect to advising the Agent as to
its rights and responsibilities under this Agreement, the Notes and the other
Loan Documents, and any modification, supplement or waiver of any of the terms
of this Agreement or any other Loan Document, (b) all reasonable costs and
expenses of any Lender, including reasonable legal fees and expenses, in
connection with the enforcement of, or preservation of rights under this
Agreement, the Notes and the other Loan Documents and (c) reasonable costs and
expenses incurred in connection with third party professional services required
by the Agent such as appraisers, environmental consultants, accountants or
similar Persons, PROVIDED THAT, prior to any Event of Default hereunder, the
Agent will first obtain the consent of the Company to such expense, which
consent shall not be unreasonably withheld. Without prejudice to the survival of
any other obligations of the Company hereunder and under the Notes, the
obligations of the Company under this SECTION 11.04 shall survive the
termination of this Agreement or the replacement of the Agent and each
assignment of the Notes.

              SECTION 11.05 INDEMNITY. (a) The Company shall indemnify the
Agent, the Co-Documentation Agents and each Lender and each Affiliate thereof
and their respective directors, officers, employees and agents (OTHER THAN WITH
RESPECT TO ANY CLAIMS BY THE AGENT, THE CO-DOCUMENTATION AGENTS AND/OR ANY
LENDER OR AFFILIATE, DIRECTOR, OFFICER, EMPLOYEE OR AGENT THEREOF AGAINST THE
AGENT, THE CO-DOCUMENTATION AGENTS OR ANY LENDER, OR ANY AFFILIATE, DIRECTOR,
OFFICER, EMPLOYEE OR AGENT THEREOF) (such indemnified Persons called the
"Indemnitees") from, and hold each of them harmless against, any and all losses,
liabilities, claims or damages (including reasonable legal fees and expenses) to
which any of them may become subject, insofar as such losses, liabilities,
claims or damages arise out of or result from (i) this Agreement, the Notes or
any other Loan Document or any actual or proposed use by the Company of the
proceeds of any extension of credit hereunder, (ii) any investigation,
litigation, claims, or demands under any Environmental Laws, or (iii) any other
proceeding (including any threatened investigation or proceeding) relating to
the foregoing clauses (i) and (ii), whether in each such case arising as a
result of this Agreement or any of the other Loan Documents or the transactions
contemplated hereby, and the Company shall reimburse such Indemnitees, upon
demand for any expenses (including legal fees) reasonably incurred in connection
with any such investigation or proceeding; but excluding any such losses,
liabilities, claims, damages or expenses incurred by reason of the gross
negligence or willful misconduct of the Indemnitees. WITHOUT LIMITING ANY
PROVISION OF THIS AGREEMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO
THAT EACH INDEMNITEE SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ALL SUCH
LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISING OUT OF OR RESULTING FROM THE SOLE
ORDINARY OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNITEE, BUT NOT FROM THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE. Without prejudice to the
survival of any other obligations of the Company hereunder and under the other
Loan Documents, the obligations

                                      -75-

of the Company under this SECTION 11.05 shall survive the termination of this
Agreement and the other Loan Documents and the payment of the Obligations or the
assignment of the Notes.

              (b) Notwithstanding anything set forth herein to the contrary, the
Company shall not, in connection with any one legal proceeding or claim, or
separate but related proceedings or claims arising out of the same general
allegations of circumstances, in which the interest of the Indemnitees (in the
reasonable judgment of such Indemnitees) does not differ in any material
respect, be liable to the Indemnitees (or any of them) under any of the
provisions set forth herein for the fees or expenses of more than one separate
firm of attorneys in each jurisdiction in which legal action is being taken or
may be taken at any time, which firm shall be selected by the Agent (or, if the
Agent fails to so select after notice from the Indemnitees involved, such firm
shall be selected by such Indemnitees), except for any additional firms
reasonably recommended by such firm in good faith for purposes of obtaining
special expertise in any area of law or for purposes of having local counsel in
each court in which such proceeding or proceedings are pending. In any
litigation or other proceeding in which the interests of the Company and any
Indemnitee affected thereby are not adverse (in the reasonable judgment of such
Indemnitee) and with respect to which such Indemnitee may seek indemnification
or reimbursement from the Company hereunder, the Company shall be entitled to
participate (in conjunction with counsel for the Indemnitees), at the Company's
expense, in the defense of such litigation or proceeding with its own counsel.
No Indemnitee shall consent to entry of any judgment or enter into any
settlement of any action or proceeding that would give rise to any liability of
the Company hereunder without the prior written consent of the Company (which
consent shall not be unreasonably withheld).

              SECTION 11.06 RIGHT OF SETOFF. If any Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits held and other obligations owing by such Lender, or any
branch, subsidiary or Affiliate, to or for the credit or the account of the
Company against any and all the Obligations of the Company now or hereafter
existing under this Agreement and the other Loan Documents and other obligations
of the Company held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement, its Note or the Obligations and
although the Obligations may be unmatured. The rights of each Lender under this
SECTION 11.06 are in addition to other rights and remedies (including other
rights of setoff) which such Lender may have.

              SECTION 11.07 GOVERNING LAW. This Agreement, all Notes, the other
Loan Documents and all other documents executed in connection herewith shall be
deemed to be contracts and agreements executed by the Company and each Lender
under the laws of the State of Texas and of the United States of America and for
all purposes shall be construed in accordance with, and governed by, the laws of
said state and of the United States of America. Without limitation of the
foregoing, nothing in this Agreement, or in the Notes or in any other Loan
Document shall be deemed to constitute a waiver of any rights which any Lender
may have under applicable federal legislation

                                      -76-

relating to the amount of interest which such Lender may contract for, take,
receive or charge in respect of the Loan and the Loan Documents, including any
right to take, receive, reserve and charge interest at the rate allowed by the
law of the state where any Lender is located. The Agent, each Lender and the
Company further agree that insofar as the provisions of Article 5069-1.04, of
the Revised Civil Statutes of Texas, as amended, are applicable to the
determination of the Highest Lawful Rate with respect to the Notes and the
Obligations hereunder and under the other Loan Documents, the indicated rate
ceiling of such Article shall be applicable; PROVIDED, HOWEVER, that to the
extent permitted by such Article, the Agent may from time to time by notice to
the Company revise the election of such interest rate ceiling as such ceiling
affects the then current or future balances of the Loans. The provisions of
Article 5069-15.01 ET. SEQ. do not apply to any Loan, this Agreement, any Note
issued hereunder or the other Loan Documents.

              SECTION 11.08 INTEREST. It is the intention of the parties hereto
that the Agent and each Lender shall conform strictly to usury laws applicable
to it, if any. Notwithstanding anything to the contrary set forth herein, in any
other Loan Document or in any other document or instrument, no provision of any
of the Loan Documents or any other instrument or document furnished pursuant
hereto or in connection herewith is intended or shall be construed to require
the payment or permit the collection of interest in excess of the maximum
non-usurious rate permitted by applicable law. Each provision in this Agreement
and each other Loan Document, agreement or writing is expressly limited so that
in no event whatsoever shall the amount paid, or otherwise agreed to be paid, to
the Agent or any Lender, or charged, contracted for, reserved, taken or received
by the Agent or any Lender, for the use, forbearance or detention of the money
to be loaned under this Agreement or any Loan Document or otherwise (including
any sums paid as required by any covenant or obligation contained herein or in
any other Loan Document which is for the use, forbearance or detention of such
money), exceed that amount of money which would cause the effective rate of
interest to exceed the Highest Lawful Rate, and all amounts owed under this
Agreement and each other Loan Document shall be held to be subject to reduction
to the effect that such amounts so paid or agreed to be paid, charged,
contracted for, reserved, taken or received which are for the use, forbearance
or detention of money under this Agreement or such Loan Document shall in no
event exceed that amount of money which would cause the effective rate of
interest to exceed the Highest Lawful Rate. If the transactions with any Lender
contemplated hereby would be usurious under applicable law then, in that event,
notwithstanding anything to the contrary in any Note payable to such Lender,
this Agreement, any other Loan Document or any other document or instrument, it
is agreed that in the event that the maturity of any Note payable to such Lender
is accelerated or in the event of any required or permitted prepayment, then
such consideration that constitutes interest under law applicable to such Lender
may never include more than the maximum amount allowed by such applicable law
and excess interest, if any, to such Lender provided for in this Agreement or
otherwise shall be canceled automatically as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the indebtedness owed to such Lender by the Company and any
excess refunded by such Lender to the Company. Anything in any Note or any other
Loan Document to the contrary notwithstanding, the Company shall not be

HOU04:29529.11
                                             -77-





required to pay unearned interest on any Note and the Company shall not be
required to pay interest on the Obligations at a rate in excess of the Highest
Lawful Rate, and if the effective rate of interest which would otherwise be
payable under such Note and such Loan Documents would exceed the Highest Lawful
Rate, or if the holder of such Note shall receive any unearned interest or shall
receive monies that are deemed to constitute interest which would increase the
effective rate of interest payable by the Company under such Note and the other
Loan Documents to a rate in excess of the Highest Lawful Rate, then (a) the
amount of interest which would otherwise be payable by the Company shall be
reduced to the amount allowed under applicable law and (b) any unearned interest
paid by the Company or any interest paid by the Company in excess of the Highest
Lawful Rate shall in the first instance be credited on the principal of the
Obligations of the Company (or if all such Obligations shall have been paid in
full, refunded to the Company). It is further agreed that, without limitation of
the foregoing, all calculations of the rate of interest contracted for,
reserved, taken, charged or received by any Lender under the Notes, the
Obligations and the other Loan Documents or made for the purpose of determining
whether such rate exceeds the Highest Lawful Rate, shall be made, to the extent
permitted by usury laws applicable to such Lender, by amortizing, prorating and
spreading in equal parts during the period of the full stated term of the Notes
and this Agreement.

              SECTION 11.09 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties contained herein or made in writing by the
Company in connection herewith and the other Loan Documents shall survive the
execution and delivery of this Agreement, the Notes and the other Loan
Documents, the termination of the Total Commitment of the Lenders and will bind
and inure to the benefit of the respective successors and assigns of the parties
hereto, whether so expressed or not, PROVIDED, that the Total Commitment of the
Lenders shall not inure to the benefit of any non-approved successor or assign
of the Company.

              SECTION 11.10 SUCCESSORS AND ASSIGNS; PARTICIPATIONS. (a) All
covenants, promises and agreements by or on behalf of the Company or the Lenders
that are contained in this Agreement shall bind and inure to the benefit of
their respective permitted successors and assigns. The Company may not assign or
transfer any of its rights or obligations hereunder without the consent of the
Lenders.

              (b) Any of the Lenders may assign to or sell participations to an
Eligible Assignee a portion of its rights and obligations under this Agreement
and the other Loan Documents (including a portion of its share of the Total
Commitment, the Advances and the Obligations of the Company owing to it and the
Notes); PROVIDED, that, in the case of participations (i) such Eligible
Assignees shall be entitled to the cost protection provisions contained in
ARTICLE II and SECTION 11.04 to the extent the Lender selling the participation
is so entitled, (ii) the Company shall continue to deal solely and directly with
the Agent in connection with its rights and obligations under this Agreement and
the other Loan Documents and (iii) each Lender shall retain the sole right and
responsibility to enforce the Obligations relating to the Loans including,
without limitation, the right to approve any amendment, modification or waiver
of any provision of this Agreement; but such Lender may grant

                                      -78-

a participant rights only to the extent such amendments, modifications or
waivers would effect such participant's interests in any fees payable hereunder
(including, without limitation, the amount and the dates fixed for payment of
any such fees) or the amount of principal or the rate of interest payable on, or
the dates fixed for any payment of principal or of interest on, the Loans.
Except with respect to cost protections provided to a participant pursuant to
this paragraph hereof, no participant shall be a third party beneficiary of this
Agreement nor shall it be entitled to enforce any rights provided to the Lenders
against the Company under this Agreement.

              (c) A Lender may assign to any other Lender and, with the prior
written consent of the Company and the Agent (which consents shall not be
unreasonably withheld), a Lender may assign to one or more other Eligible
Assignees all or a portion of its interests, rights, and obligations under this
Agreement and the other Loan Documents (including all or a portion of its share
of the Total Commitment and the same portion of the Loans and other obligations
of the Company at the time owing to it and the Note held by it); PROVIDED,
HOWEVER, that each such assignment (i) shall be in a minimum principal amount of
not less than $10,000,000.00 or such Lender's remaining Commitment (other than
any assignment from any Lender of the Term Loan B in which case in a minimum
principal amount of not less than $5,000,000.00), (ii) shall not reduce any
Lender's Commitment to an amount less than $10,000,000.00 (other than to zero or
other than any Lender of the Term Loan B in which case in a minimum amount of
not less than $5,000,000.00) and shall be of a constant, and not a varying,
percentage of the assigning Lender's Revolving Credit Commitment, Term Loan A
Commitment, ESOP Loan Commitment and the rights and obligations attendant to
such Commitments under this Agreement, (iii) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance, an Assignment and
Acceptance in form and substance satisfactory to the Agent (an "ASSIGNMENT AND
ACCEPTANCE") substantially in the form of EXHIBIT 11.10 hereto, and any Note
subject to such assignment and (iv) no assignment shall be effective until
receipt by the Agent of a reasonable service fee in respect of said assignment
equal to $2,500.00. Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Assignment and Acceptance,
which effective date shall be at least five Business Days after the execution
thereof unless otherwise agreed to by the assigning Lender, the Eligible
Assignee thereunder and the Agent (x) the Eligible Assignee thereunder shall be
a party hereto and to the other Loan Documents and, to the extent provided in
such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and under the other Loan Documents and (y) the assignor Lender
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement and the other Loan Documents
(and, in the case of an Assignment and Acceptance covering all of the remaining
portion of an assigning Lender's rights and obligations under this Agreement and
the other Loan Documents, such Lender shall cease to be a party hereto except,
in the case of an Issuing Bank, with respect to Letters of Credit issued by such
Issuing Bank which are then outstanding).

              (d) The Agent shall maintain at its office (i) a copy of each
Assignment and Acceptance delivered to it and (ii) a register (the "REGISTER")
for the recordation of the names and

                                      -79-

addresses (and taxpayer identification numbers, if any) of the Lenders and the
principal amount and types of Loans owing to each Lender pursuant to the terms
hereof from time to time. The entries in the Register shall be conclusive in the
absence of manifest error, and the Company, the Agent, the Swing Line Lender and
the Lenders shall treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a "Lender" hereunder for all purposes of this
Agreement and the Loan Documents. The Register shall be available for inspection
by the Company, the Agent, the Swing Line Lender and any Lender at any
reasonable time and from time to time upon reasonable prior notice.

       (e) Upon its receipt of a copy of (or copies of signed counterparts of) a
duly completed and fully executed Assignment and Acceptance, together with the
existing Note or Notes of the assigning Lender subject to such Assignment and
Acceptance, the Agent shall (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register and (iii) give prompt
notice thereof to the Company and the affected Lenders. Not later than five (5)
Business Days after the receipt of the notice from the Agent referred to in
clause (iii) above, the Company, at its own expense, shall execute and deliver
to the Agent, in exchange for the Note or Notes of the assigning Lender
surrendered to the Agent pursuant to this paragraph, a new Note or Notes payable
to the order of the assignee Lender and its registered assigns in the principal
amount of the Loans assigned to it. Any such new Note shall be substantially in
the form of EXHIBIT 2.05A, 2.05B, 2.05C, 2.05D and 2.05E, hereto as appropriate.
Cancelled Notes shall be promptly returned to the Company.

              (f) Notwithstanding any other provision herein but subject to
SECTION 11.11, any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this SECTION
11.10(F) disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Company or any Subsidiary furnished
to such Lender by or on behalf of the Company or any Subsidiary.

              (g) Anything in this SECTION 11.10 to the contrary
notwithstanding, any Lender may at any time, without the consent of the Company
or the Agent, assign and pledge all or any portion of its Commitments and the
Loans owing to it to any Federal Reserve Bank (and its transferees) as
collateral security pursuant to Regulation A of the Board and any Operating
Circular issued by such Federal Reserve Bank. No such assignment shall release
the assigning Lender from its obligations hereunder.

              SECTION 11.11 CONFIDENTIALITY. Each Lender agrees to exercise its
best efforts to keep any information delivered or made available by the Company
confidential from anyone other than Persons employed or retained by such Lender
who are or are expected to become engaged by such Lender in evaluating,
approving, structuring or administering the Loans and who are subject to this
confidentiality provision; PROVIDED that nothing herein shall prevent any Lender
from disclosing such information (a) to any other Lender, (b) pursuant to
subpoena or upon the order of any court

                                      -80-

or administrative agency, (c) upon the request or demand of any regulatory
agency (including self regulatory agencies) or authority having jurisdiction
over such Lender, (d) which has been publicly disclosed, (e) to the extent
reasonably required in connection with any litigation to which the Agent, any
Lender, the Company or its respective Affiliates may be a party, (f) to the
extent reasonably required in connection with the exercise of any remedy
hereunder, (g) to such Lender's legal counsel and independent auditors (who are
subject to this confidentiality provision or similar confidentiality provision)
(h) to any actual or proposed participant or assignee of all or part of its
rights hereunder which has agreed in writing to be bound by the provisions of
this SECTION 11.11 and (i) which is clearly not confidential. To the extent
legally permitted, each Lender will use its best reasonable efforts to promptly
notify the Company of any information that it is required or requested to
deliver pursuant to clause (b), (c) or (e) of this SECTION 11.11; PROVIDED that
no notice shall be required for any review of information by representatives of
regulators at any Lender's places of business.

              SECTION 11.12 PRO RATA TREATMENT. (a) Except as otherwise
specifically permitted hereunder, each payment or prepayment of principal, if
permitted under this Agreement, and each payment of interest with respect to an
Advance shall be made pro rata among the Lenders on the basis of their
respective percentage participations in the Revolving Credit Commitment, the
ESOP Loan Commitment, the Term Loan A Commitment or the Term Loan B Commitment,
as the case may be.

              (b) Each Lender agrees that if, through the exercise of a right of
banker's lien, setoff or claim of any kind against the Company as a result of
which the unpaid principal portion of the Notes and the Obligations held by it
shall be proportionately less than the unpaid principal portion of the Notes and
Obligations held by any other Lender, it shall be deemed to have simultaneously
purchased from such other Lender a participation in the Notes and Obligations
held by such other Lender, in the amount required to render such amounts
proportional; PROVIDED, HOWEVER, that if any such purchase or purchases or
adjustments shall be made pursuant to this SECTION 11.12(B) and the payment
giving rise thereto shall thereafter be recovered, such purchase or purchases or
adjustments shall be rescinded to the extent of such recovery and the purchase
price or prices or adjustments restored without interest.

              SECTION 11.13 SEPARABILITY. Should any clause, sentence, paragraph
or Section of this Agreement be judicially declared to be invalid, unenforceable
or void, such decision will not have the effect of invalidating or voiding the
remainder of this Agreement, and the parties hereto agree that the part or parts
of this Agreement so held to be invalid, unenforceable or void will be deemed to
have been stricken herefrom and the remainder will have the same force and
effectiveness as if such part or parts had never been included herein.

              SECTION 11.14 EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of 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 taken together shall constitute one and the same
agreement.

                                      -81-

     the Trust.
 
     The following is a list of threatened litigation, as of May 14, 1996,
against Texas Petrochemicals Corporation ("TPC"):
 
     1. Claims for indemnity from Petro-Texas Chemical Corporation
        ("Petro-Tex"). On February 4, 1992, counsel for Petro-Tex requested
        TPC to indemnify Petro-Texas with respect to the following litigation:
 
        (a) PAULA JEAN BOUDREAUX ET AL. V. TEXAS CHEMICAL COMPANY, ET AL.; No.
            B141,684, 60th District Court of Jefferson County, Texas.

                CHEMICAL COMPANY, ET AL.; in the 60th Judicial District Court of

                Texas ("Fuller Lawsuit").
 
     3. Claim for indemnity from Tenneco to TPC. On December 9, 1993, counsel
        for Tenneco requested TPC to indemnify Petro-Tex with respect to the
        following cases:
 
        (a)     ADAMS, ET AL. V. AMOCO CHEMICAL, ET AL.; No. 93-045837, in the
                234th Judicial District Court of Harris County, Texas;
 
        (b)     ALLCORN, ET AL. V. AMOCO CHEMICAL, ET AL.; No. 93-042492, in the

     4. Claim for indemnity from Tenneco to TPC. On April 14, 1994, counsel for
        Tenneco requested TPC to indemnify Petro-Tex under the purchase
        agreement between Petro-Tex and TPC dated June 8, 1994.
 
     5. Claim for indemnity from Tenneco to TPC. On May 12, 1994, counsel for
        Tenneco again reasserted Petro-Tex's position that TPC was obligated to
        indemnify Petro-Tex for all claims alleged in the above cases.
 
     6. Claim for indemnity from Tenneco to TPC. On July 15, 1994, TPC received
        notice for indemnification from counsel for Tenneco for Malone Service
        Company -- Environmental Claim.
 
     Counsel for TPC has repeatedly advised counsel for Tenneco and Petro-Tex
that TPC did not assume any of the liabilities for which Petro-Tex was seeking
indemnity. Counsel for TPC further advised Petro-Tex that TPC was not obligated
to indemnify Petro-Tex in connection with various tort claims arising from the
sale of products by Petro-Tex prior to June 21, 1984.
 
     To the actual knowledge of officers of TPC, no litigation has been
initiated by either Tenneco or Petro-Tex for indemnification to Petro-Tex with
respect to any of the above claims.
 
                                 SCHEDULE 6.12
 
                             Environmental Matters
 
     1.  The No. 1 Dehydro Reactor emits greater than 5 tons per year of carbon
         monoxide but does not burn at a temperature equal to or greater than
         1300 degrees farenheit, in contravention of 30 Tex. Admin. Code Section
         119.2. The installation of a duct burner and new waste heat boiler, to
         be completed by November 1996, is to correct this concern.
 
     2.  Solid waste construction debris is stored in the construction parking
         lot without a permit.
 
     3.  The Company's air emissions permit requires a 3 inch vacuum for
         servicing of inerted vessels at the Company's docks, which vacuum the
         Company does not have. The Company has submitted an application to
         amend the permit.
 
     4.  Bayer has been named in a suit against the Washburn Tunnel Facility of
         the Gulf Coast Waste Disposal Authority (GCWDA) regarding the disposal
         of various wastes disposed by the GCWDA. The Company also has sent
         non-hazardous wastes to the Washburn Tunnel Facility.
 
     5.  The Company has received complaints from its neighbors on occasion
         concerning noise, and has installed a 16-foot earthen noise barrier at
         the facility's southeast boundary to address those complaints and
         comply with the City of Houston noise ordinance.
 
     6.  The issues identified in the environmental, health and safety
         assessment and the database summary of the commercial properties
         conducted by Pilko & Associates, Inc. and dated, respectively, April
         18, 1996 and May 28, 1996.
 
     7.  In February 1996, the EPA issued an order to the Company and Bayer
         Corporation requiring the companies to resolve the exceedances of their
         discharge permit limits for copper and total suspended solids that had
         occurred since 1992. The Company believes that these issues have been
         resolved by raising the limits in the new discharge permit and by other
         corrective actions. No penalty was assessed.
 
     8.  Under the terms of the 1984 purchase agreement with Petro-Tex, the
         prior owner of the Houston facility, Petro-Tex has indemnified the
         Company for liability arising from off-site disposal of any materials
         prior to June 1984. Notwithstanding the terms of the indemnity, in July
         1994, Petro-Tex filed a claim for indemnity against the Company for any
         costs that may be attributable to Petro-Tex for the cleanup of the
         Malone Service Company site in Texas City, Texas, where Petro-Tex and
         other companies along the Gulf Coast allegedly sent wastes for disposal
         in the 1970s and early 1980s. It is not known whether the site will
         require remediation or at what cost. The Company believes that it has
         meritorious defenses to Petro-Tex's claim and intends to contest the
         claim vigorously.

                                PLEDGE AGREEMENT
 
     THIS PLEDGE AGREEMENT (this "PLEDGE AGREEMENT") dated effective as of
July 1, 1996 is between TPC FINANCE CORP., a Texas corporation to be merged into
TEXAS PETROCHEMICALS CORPORATION, a Texas corporation (collectively the
"PLEDGOR"), to TEXAS COMMERCE BANK NATIONAL ASSOCIATION, a national banking
association, as agent (the "AGENT") for the benefit of the Agent and the
lenders (the "LENDERS") party to the Credit Agreement (as defined below).
 
                             PRELIMINARY STATEMENT
 
     The Lenders, the Agent, ABN AMRO North America, Inc., as agent for ABN AMRO
Bank N.V. and The Bank of Nova Scotia, as co-documentation agents, and the
Pledgor entered into a Credit Agreement dated as of even date herewith (said
Credit Agreement, as it may hereafter be amended or otherwise modified from time
to time, being the "CREDIT AGREEMENT"), pursuant to which the Lenders agreed
to make the following Loans to the Pledgor: (a) revolving credit loans of up to
$40,000,000.00; (b) a term loan of up to $85,000,000.00; (c) a second term loan
of up to $45,000,000.00; and (d) a third term loan of up to $10,000,000.00. All
capitalized terms used herein and not otherwise defined shall have the meanings
as defined in the Credit Agreement.
 
     The Pledgor is the owner of 1,000 shares of capital stock of the Texas
Butylene Chemical Corporation, a Texas corporation and wholly owned subsidiary
of the Pledgor (the "PLEDGED SHARES") evidenced by Certificate No. 2. It is a
condition precedent to the obligations of the Agent to make the Loans under the
Credit Agreement that the Pledgor shall have executed and delivered this Pledge
Agreement.
 
     NOW THEREFORE, in consideration of the premises and in order to induce the
Lenders to make available to the Pledgor the Loans under the Credit Agreement
the Pledgor hereby agrees as follows:
 
     SECTION 1. DEFINED TERMS
 
          (a) The term "UCC" means the Uniform Commercial Code as in effect on
     the date hereof in the State of Texas; PROVIDED that if by mandatory
     provisions of law, the perfection or the effect or perfection or
     non-perfection of the security interests granted pursuant to SECTION 2
     hereof, as well as all other security interests created or assigned as
     additional security for the Secured Obligations (as defined below in
     SECTION 3) pursuant to the provisions of this Pledge Agreement, in any
     Pledged Collateral is governed by the UCC as in effect in such other
     jurisdiction other than Texas, "UCC" means the UCC as in effect in such
     other jurisdiction for purposes of the provisions hereof relating to such
     perfection or effect of perfection or non-perfection.
 
          (b) The term "Issuer" means Texas Butylene Chemical Corporation, a
     Texas corporation and wholly owned subsidiary of the Pledgor.
 
     SECTION 2. PLEDGE. The Pledgor hereby pledges to the Agent for the benefit
of itself and the Lenders, and grants to the Agent for the benefit of itself and
the Lenders a security interest in, the following (the "PLEDGED COLLATERAL"):
 
          (i) the Pledged Shares and the certificates representing the Pledged
     Shares, and all dividends, cash, instruments and other property from time
     to time received, receivable or otherwise distributed in respect of or in
     exchange for any or all of the Pledged Shares;
 
          (ii) all additional shares of stock of Issuer from time to time
     acquired by the Pledgor in any manner, and the certificates representing
     such additional shares, and all dividends, cash, instruments and other
     property from time to time received, receivable or otherwise distributed in
     respect of or in exchange for any or all of such shares; and
 
          (iii) all proceeds of any of the foregoing.
 
     The inclusion of proceeds in this Pledge Agreement does not authorize the
Pledgor to sell, dispose of or otherwise use the Pledged Collateral in any
manner not specifically authorized hereby.
 
     SECTION 3. SECURITY FOR OBLIGATIONS. This Pledge Agreement secures the
prompt and complete (a) payment of all obligations of the Company to the Agent
and the Lenders now or hereafter existing under the Credit Agreement, the Notes
and the other Loan Documents, (b) the performance and observance by the Company
of all covenants and conditions contained in all of the Loan Documents, whether
for principal, interest, fees, expenses or otherwise and (c) the performance and
observance by the Pledgor of all covenants and conditions contained in this
Pledge Agreement (all such obligations, covenants and conditions described in
the foregoing clauses (a), (b), and (c) being hereinafter referred to as the
"SECURED OBLIGATIONS").
 
     SECTION 4. DELIVERY OF PLEDGED COLLATERAL. All certificates or instruments
representing or evidencing the Pledged Collateral shall be delivered to and held
by or on behalf of the Agent pursuant hereto and shall be in suitable form for
transfer by delivery, or shall be accompanied by duly executed instruments of
transfer or assignment in blank, all in form and substance satisfactory to the
Agent. Upon the occurrence and during the continuance of any Event of Default,
the Agent shall have the right, upon the instruction of the Majority Lenders and
without notice to the Pledgor, to transfer to or to register in the name of the
Agent or the Lenders or any of their respective nominees any or all of the
Pledged Collateral, subject only to the revocable rights specified in SECTION 7
(A) hereof. In addition, upon the occurrence and during the continuance of any
Event of Default, the Agent shall have the right at any such time to exchange
certificates or instruments representing or evidencing Pledged Collateral for
certificates or instruments of smaller or larger denominations.
 
                                       2

     SECTION 5. REPRESENTATIONS AND WARRANTIES. In addition to the
representations and warranties of the Pledgor under the Credit Agreement, the
Pledgor represents and warrants as follows:
 
     (a) The Pledged Shares have been duly authorized and validly issued and are
fully paid and non-assessable.
 
     (b) The Pledgor is the legal and beneficial owner of the Pledged Collateral
free and clear of any Lien except for Permitted Liens, if any, and Liens created
in favor of the Agent.
 
     (c) The delivery of the Pledged Shares to the Agent and this Pledge
Agreement, together with the filing of an appropriate financing statement with
the Texas Secretary of State is sufficient to create a valid and perfected first
priority Lien in the Pledged Collateral, subject only to Permitted Liens, if
any, securing the Secured Obligations.
 
     (d) The Pledged Shares constitute one hundred percent (100%) of the issued
and outstanding common stock of Issuer.
 
     SECTION 6. FURTHER ASSURANCES. The Pledgor agrees that from time to time,
at the expense of the Pledgor, the Pledgor will promptly execute and deliver all
further instruments and documents, and take all further action that the Agent or
the Majority Lenders may reasonably request as being necessary or desirable, in
order to perfect and protect any security interest granted or purported to be
granted hereby or to enable the Agent or any Lender to exercise and enforce its
rights and remedies hereunder with respect to any Pledged Collateral. The
Pledgor will furnish to the Agent from time to time statements and schedules
further identifying and describing the Pledged Collateral and such other reports
in connection with the Pledged Collateral as the Agent or any Lender may
reasonably request, all in reasonable detail as the Agent or any Lender may
reasonably request. The Pledgor agrees to deliver, upon its receipt from
issuance thereof, to the Agent or any Lender any certificate or other evidence
of Issuer evidencing any Pledged Shares issued after the date hereof, and such
shall be in suitable form for transfer by delivery, or shall be accompanied by
duly executed instruments of transfer or assignment in blank, all in form and
substance satisfactory to the Agent or such Lender.
 
     SECTION 7. VOTING RIGHTS AND DIVIDENDS. (a) So long as no Event of Default
shall have occurred and be continuing and the Agent has not delivered the notice
specified in SECTION 7(B):
 
          (i) The Pledgor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to the Pledged Collateral or any part
     thereof for any purpose not inconsistent with the terms of this Pledge
     Agreement or the Loan Documents.
 
          (ii) The Pledgor shall be entitled to receive and retain any and all
     dividends paid in respect of the Pledged Collateral; PROVIDED, except as
     expressly permitted by the Credit 

                                       3

     Agreement, that any and all (A) dividends paid or payable other than in

     or otherwise distributed in respect of, or in exchange for, any Pledged

     are outstanding, to hold as, Pledged Collateral and shall, if received by
     the Pledgor, be received in trust for the benefit of the Agent, be
     segregated from the other property or funds of the Pledgor, and be
     forthwith delivered to the Agent as Pledged Collateral in the same form as
     so received (with any necessary endorsement).
 
          (iii) The Agent shall execute and deliver (or cause to be executed and
     delivered) to the Pledgor all such proxies and other instruments as the
     Pledgor may reasonably request for the purpose of enabling the Pledgor to
     exercise the voting and other rights which it is entitled to exercise
     pursuant to paragraph (i) above and to receive the dividends which it is
     authorized to receive and retain pursuant to paragraph (ii) above.
 
     (b) Upon the occurrence and during the continuance of an Event of Default,
at the option of the Agent exercised in a writing sent to the Pledgor:
 
          (i) All rights of the Pledgor to exercise the voting and other
     consensual rights which it would otherwise be entitled to exercise pursuant
     to SECTION 7(A)(I) shall cease, and the Agent shall thereupon have the sole
     right to exercise such voting and other consensual rights.
 
          (ii) All rights of the Pledgor to receive the dividends which it would
     otherwise be entitled to receive and retain pursuant to SECTION 7(A)(II)
     shall cease, and the Agent for the benefit of the Lenders shall thereupon
     have the sole right to receive and apply against the Obligations or, if no
     Obligations are outstanding, hold as Pledged Collateral such dividends and
     interest.
 
          (iii) All dividends which are received by the Pledgor contrary to the
     provisions of paragraph (ii) of this Section shall be received in trust for
     the benefit of the Agent, shall be segregated from other funds of the
     Pledgor and shall be forthwith paid over to the Agent as Pledged Collateral
     in the same form as so received (with any necessary endorsement).
 
     SECTION 8. TRANSFERS AND OTHER LIENS; ADDITIONAL SHARES. (a) Except as
permitted in the Credit Agreement, the Pledgor shall not: (i) sell, assign (by
agreement, operation of law or otherwise) or otherwise dispose of, or grant any
option with respect to, any of the Pledged Collateral, or (ii) create or permit
to exist any Lien upon or with respect to any of the Pledged Collateral, except
for the Lien created by this Pledge Agreement, Permitted Liens and any other
Lien in favor of the Agent.
 
                                       4

          (b) The Pledgor agrees that it will cause Issuer not to issue any
     stock or other securities (i) in substitution for the Pledged Shares,
     except to the Pledgor and (ii) in addition to the Pledged Shares, except in
     such amounts and to such holders as will maintain the percentage of
     ownership set forth in SECTION 5(D) hereof for the Pledgor, except as
     otherwise permitted by SECTION 8.02 of the Credit Agreement. Immediately
     upon its acquisition (directly or indirectly) of any such substitute or
     additional shares of stock or other securities of any Issuer, the Pledgor
     will execute such documentation as requested by Agent pledging, and
     evidencing the pledge hereunder of, such shares of stock or other
     securities.
 
     SECTION 9. AGENT APPOINTED ATTORNEY IN FACT. Effective upon the occurrence
and during the continuance of an Event of Default under any Loan Document, the
Pledgor hereby irrevocably appoints the Agent the Pledgor's attorney in fact,
with full authority in the place and stead of the Pledgor and in the name of the
Pledgor, from time to time in the Agent's sole discretion to take any action and
to execute any instrument which the Agent may deem necessary or advisable to
accomplish the purposes of this Pledge Agreement, including, without limitation,
to receive, endorse and collect all certificates or instruments made payable to
the Pledgor representing any dividend or other distribution in respect of the
Pledged Collateral or any part thereof and to give full discharge for the same.
 
     SECTION 10. AGENT MAY PERFORM. If the Pledgor fails to perform any
agreement contained herein, the Agent may itself, during the existence of an
Event of Default, perform, or cause performance of, such agreement, and the
expenses of the Agent incurred in connection therewith shall be payable by the
Pledgor under SECTION 11.04 of the Credit Agreement.
 
     SECTION 11. THE AGENT'S DUTIES. The powers conferred on the Agent hereunder
are solely to protect its interest in the Pledged Collateral and shall not
impose any duty upon it to exercise any such powers. Except for reasonable care
in the custody of any Pledged Collateral in its possession and the accounting
for moneys actually received by it hereunder, the Agent shall have no duty as to
any Pledged Collateral or as to the taking of any necessary steps to preserve
rights against prior parties or any other rights pertaining to any Pledged
Collateral. The Agent shall be deemed to have exercised reasonable care in the
custody and preservation of the Pledged Collateral in its possession if the
Pledged Collateral is accorded treatment substantially equal to that which the
Agent accords its own property, it being understood that the Agent shall not
have any responsibility for (a) ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relative to
any Pledged Collateral, whether or not the Agent has or is deemed to have
knowledge of such matters, or (b) taking any necessary steps to preserve rights
against any parties with respect to any Pledged Collateral.
 
     SECTION 12. REMEDIES UPON DEFAULT. If any Event of Default under the Loan
Documents shall have occurred and be continuing:

                                       5
 
          (a) The Agent may exercise in respect of the Pledged Collateral, in
     addition to other rights and remedies provided for herein or otherwise
     available to it, all the rights and remedies of a Agent on default under
     the UCC (whether or not the UCC applies to the affected Pledged
     Collateral), and the Agent may also, without notice except as specified
     below, sell the Pledged Collateral or any part thereof in one or more
     parcels at public or private sale, at any exchange, broker's board or at
     any of the Agent's offices or elsewhere, for cash or credit, and upon such
     other terms as may be commercially reasonable. The Pledgor agrees that at
     least ten (10) days' notice to the Pledgor of the time and place of any
     public sale or the time after which any private sale is to be made shall
     constitute reasonable notification. The Agent shall not be obligated to
     make any sale of Pledged Collateral regardless of notice of sale having
     been given. The Agent may adjourn any public or private sale from time to
     time by announcement at the time and place fixed therefor, and such sale
     may, without further notice, be made at the time and place to which it was
     so adjourned.
 
          (b) Any cash received by the Agent in respect of any sale of,
     collection from, or other realization upon all or any part of the Pledged
     Collateral shall be applied by the Lenders against the outstanding
     Obligations, and if no Obligations are outstanding, such cash may be held
     by the Agent upon the instruction of the Majority Lenders as collateral
     for, and/or then or at any time thereafter applied (after payment of any
     amounts payable to the Agent pursuant to SECTION 11.04 of the Credit
     Agreement) in whole or in part by the Lenders against, all or any part of
     the Secured Obligations in such order as each Lender shall elect. Any
     surplus of such cash or cash proceeds held by the Agent and remaining after
     payment in full of all the Secured Obligations shall be paid over to the
     Pledgor or to whomsoever may be lawfully entitled to receive such surplus.
 
          (c) In connection with the sale of any Pledged Collateral, the Agent
     is authorized, but not obligated, to limit prospective purchasers to the
     extent deemed reasonably necessary or desirable by the Agent to render such
     sale exempt from the registration requirements of the Securities Act of
     1933, as amended (the "SECURITIES ACT"), and any applicable state
     securities laws and regulations, and no sale so made in good faith by the
     Agent shall be deemed not to be "commercially reasonable" solely as a
     result of such limit of prospective purchasers.
 
          (d) All rights and remedies of the Agent for the benefit of itself and
     the Lenders expressed herein are in addition to all other rights and
     remedies possessed by the Agent in the Loan Documents and any other
     agreement or instrument relating to the obligations.
 
          (e) In connection with a public or private sale by the Agent pursuant
     to this SECTION 12 of the Pledged Collateral or any part thereof, the Agent
     may disclose, in accordance with SECTION 11.11 of the Credit Agreement, to
     prospective purchasers any and all non-public information available to the
     Agent which pertains to (i) Issuer of the Pledged Collateral, or (ii) the
     Pledgor, provided in the case of the Pledgor, such non-public information
     is material to said issuer, its financial condition or the Pledged
     Collateral.

                                       6
 
     SECTION 13. PRIVATE SALES; FURTHER ASSURANCES. The Pledgor recognizes that
the Agent may be unable to effect a public sale of any or all of the Pledged
Collateral by reason of certain prohibitions contained in the laws of any
jurisdiction outside the United States or in the United States Securities Act of
1933 (the "1933 ACT") and applicable state securities laws, but may instead be
compelled to resort to one or more private sales thereof to a restricted group
of purchasers who will be obliged to agree, among other things, to acquire such
Pledged Collateral for their own account for investment and not with a view to
the distribution or resale thereof. The Pledgor acknowledges and agrees that any
such private sale by the Agent may result in prices and other terms less
favorable to the seller than if such sale were a public sale and,
notwithstanding such circumstances, agrees that no such private sale shall, to
the extent permitted by applicable law, be deemed not to be "commercially
reasonable" solely as a result of such prices and other sale terms. The Agent
shall not be under any obligation to delay a sale of any of the Pledged
Collateral for the period of time necessary to permit Issuer of such securities
to register such securities under the laws of any jurisdiction outside the
United States, under the 1933 Act or under any applicable state securities laws,
even if Issuer would agree to do so. If the Agent is able to lawfully effect a
public sale without registration of the Pledged Collateral under the laws of any
jurisdiction outside the United States, under the 1933 Act or under any
applicable state securities laws, then the Agent may conduct such public sale of
the Pledged Collateral, rather than a private sale, if the Agent would realize a
higher sales price in such public sale.
 
     SECTION 14. AMENDMENTS. No amendment or waiver of any provision of this
Pledge Agreement, nor consent to any departure by the Pledgor herefrom, shall in
any event be effective unless the same shall be made in accordance with SECTION
11.01 of the Credit Agreement and signed by the Pledgor and the Agent, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given.
 
     SECTION 15. ADDRESSES FOR NOTICES. All notices and other communications
provided for hereunder shall be given in the manner and at the addresses of the
Pledgor and the Agent as set forth in the Credit Agreement and shall become
effective, as specified in the Credit Agreement.
 
     SECTION 16. WAIVER OF MARSHALLING. All rights of marshalling of assets of
the Pledgor, including any such right with respect to the Pledged Collateral,
are hereby waived by the Pledgor.
 
     SECTION 17. LIMITATION BY LAW. All rights, remedies and powers provided in
this Pledge Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable provision of law, and all the provisions
of this Pledge Agreement are intended to be subject to all applicable mandatory
provisions of law which may be controlling from time to time and to be limited
to the extent necessary so that they will not render this Pledge Agreement
invalid, unenforceable, in whole or in part, or not entitled to be recorded,
registered or filed under the provisions of any applicable law.
 
                                       7

     SECTION 18. SEPARABILITY. Should any clause, sentence, paragraph,
subsection or Section of this Pledge Agreement be judicially declared to be
invalid, unenforceable or void, such declaration will not have the effect of
invalidating or voiding the remainder of this Pledge Agreement, and the parties
hereto agree that the part or parts of this Pledge Agreement so held to be
invalid, unenforceable or void will be deemed to have been stricken herefrom by
the parties hereto, and the remainder of this Pledge Agreement will have the
same force and effectiveness as is such stricken part or parts had never been
included herein.
 
     SECTION 19. NO WAIVER; REMEDIES. No failure on the part of the Agent to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.
 
     SECTION 20. CONTINUING SECURITY INTEREST; TRANSFER OF NOTES. This Pledge
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until payment in full of the
Secured Obligations, (b) be binding upon the Pledgor, its successors and
assigns, and (c) inure to the benefit of the Agent for the benefit of itself and
the Lenders and their respective successors, transferees and assigns. Without
limiting the generality of the foregoing clause (c), any Lender may assign or
otherwise transfer all or a portion of its interest, rights and obligations
under the Notes held by it pursuant to SECTION 11.10 of the Credit Agreement.
Upon the payment in full of the Secured Obligations, the Pledgor shall be
entitled to the return, upon its request and at its expense, of such of the
Pledged Collateral as shall not have been sold or otherwise applied against the
Secured Obligations pursuant to the terms hereof; PROVIDED, that the Pledgor
shall otherwise be entitled to such return of the Pledged Collateral upon
payment in full of all Secured Obligations other than those arising under
SECTION 11.05 of the Credit Agreement if the Agent is not on notice of any fact,
circumstance, event or claim which reasonable construed could give rise to an
obligation of the Pledgor under such Section.
 
     SECTION 21. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties contained in this Pledge Agreement or made in writing by the
Pledgor in connection herewith are true and correct in all material respect when
made or deemed to be made and shall survive the execution and delivery of this
Pledge Agreement until repayment of the Secured Obligations. Any investigation
by the Agent shall not diminish in any respect whatsoever its rights to reply on
such representations and warranties.
