any date of determination and for the Calculation Period in which such
date occurs and for each Calculation Period thereafter to and

such Calculation Period by (b) Alternate Debt Service of the Company
and the Restricted Subsidiaries for such Calculation  



Period PLUS, at all times and to the extent the Special Subsidiary
Qualifying conditions are met, the Special Subsidiary Percentage times
the Alternate Debt Service of the Special Subsidiary for such

Debt Service with respect to such Covered Debt shall be calculated on
the basis of such fixed rate or rates for such time as the same shall
be applicable to such Covered Debt, and then at the interest rates set
forth in the most recent Approved Assumptions) in respect of Covered
Debt of such Person, in each case paid and scheduled to be paid during

of determination and for the Calculation Period in which such date

Period by (b) Debt Service of the Company and the Restricted
Subsidiaries for such Calculation Period PLUS, at all times and to the
extent the Special Subsidiary Qualifying Conditions are met, the
Special Subsidiary Percentage times the Debt Service of the Special
Subsidiary for such Calculation Period (in each case calculated on the
basis set forth in the most recent Coverage Report delivered to the
Agent pursuant to SECTION 9.1 and taking into account any incurrence
or prepayment of Covered Debt by the  Company and the Restricted 
Subsidiaries and the Special Subsidiary since the date of such
Coverage Report).

Agent of an Application therefor, to issue, and each Bank severally
agrees to purchase from the Agent a participation in (according to
such Bank's Commitment Percentage), letters of credit containing such
provisions not inconsistent with the terms of this Agreement as the
Company may reasonably request and such provisions

                                 -27-


not inconsistent with the terms of this Agreement as the Banks may
reasonably require (together with the Existing Letters of Credit, the
"LETTERS OF CREDIT") for the account of the Company and on behalf of
the Company, or for the joint and several account of and on behalf of
the Company and one or more of its Subsidiaries, as follows. From time
to time on or after the conditions herein set forth to issue such
Letters of Credit have been satisfied, and prior to the Termination
Date, the Agent shall issue and/or may have outstanding Letters of
Credit under this SECTION 2.1 in an aggregate principal amount at any

deemed, without further action by any party hereto, to have purchased

Agreement shall have an expiry date later than one year from date of
issuance. Each Bank has heretofore purchased participations in each of
the Existing Letters of Credit and the related Letter of Credit
Liabilities, to the extent of such Bank's Commitment Percentage. Such
participations are hereby ratified and confirmed and made subject
hereto. All provisions of this Agreement applicable to participations

     (b)  ADDITIONAL PROVISIONS. The following additional provisions
shall apply to each Letter of Credit:

     (i)  The Company shall give the Agent and each other Bank at
least five Business Days' irrevocable prior notice (effective upon
receipt) specifying the date such Letter of Credit is to be issued and
describing the proposed terms of such Letter of Credit and the nature
of the transaction proposed to be supported thereby. The Company shall
furnish such additional information regarding such transaction as the
Agent may reasonably request. Upon receipt of such notice, the Agent
shall promptly notify each Bank of such Bank's Commitment Percentage
of the amount of the proposed Letter of Credit and not later than two
Business Days prior to the requested issuance date for such Letter of
Credit shall furnish to each Bank and the Company a proposed form of
an Application for
                                 -28-


such Letter of Credit. The issuance by the Agent of each Letter of
Credit shall, in addition to the conditions precedent set forth in
SECTION 7, be subject to the conditions precedent that such Letter of
Credit shall be in such form and contain such terms as shall be
reasonably satisfactory to the Agent and that the Company shall have
executed and delivered to the Agent an Application and such other
instruments and agreements relating to such Letter of Credit not
inconsistent with terms of this Agreement as the Agent shall have
reasonably requested and are not inconsistent with the terms of this
Agreement.

     (ii) No Letter of Credit may be issued if after giving effect
thereto the sum of (a) the aggregate outstanding principal amount of
the Revolving Loans plus (b) the aggregate Letter of Credit
Liabilities would exceed the Available Amount. On each day during the
period commencing with the issuance of any Letter of Credit and until
such Letter of Credit shall have expired or been terminated, the
Revolving Commitment of each Bank shall be deemed to be utilized for
all purposes hereof in an amount equal to such Bank's Commitment
Percentage of the amount then or thereafter available for drawings
under such Letter of Credit.

     (iii)  In consideration of the issuance of each Letter of Credit
the Company agrees to pay to the Agent, for the ratable benefit of the
Banks, the Letter of Credit Fee. The Letter of Credit Fee shall be
payable concurrently with the issuance of each such Letter of Credit
and shall be separate from and in addition to interest on any
Reimbursement Obligation. The Agent will pay to each Bank, promptly
after receiving any payment in respect of Letter of Credit Fees, an
amount equal to such Bank's Commitment Percentage of such Letter of
Credit Fees.

     (iv)  Upon receipt from the beneficiary of any Letter of Credit
of any demand for payment thereunder, the Agent shall promptly notify
the Company and each Bank as to the amount to be paid as a result of
such demand and the payment date. If at any time the Agent shall have
made a payment to a beneficiary of a Letter of Credit in respect of a
drawing or in respect of an acceptance created in connection with a
drawing under such Letter of Credit, each Bank will pay to the Agent
immediately upon demand (or, if such demand is made after 1:00 p.m.,
on the next succeeding Business Day) by the Agent at any time during
the period commencing after such payment until reimbursement thereof
in full by the Company, an amount equal to such Bank's Commitment
Percentage of such payment, together with interest on such amount for
each day from the later of (x) the date such payment is due as
provided in the preceding sentence or (y) the date such payment is
made under such Letter of Credit to the date of payment by such Bank
of such amount at a rate of interest per annum equal to the Fed Funds
Rate for such period. No interest shall be due from any Bank that
makes full payment to the Agent on the date such payment is due.
Nothing herein shall be deemed to require any Bank to pay to the Agent
any
                                 -29-


amount as reimbursement for any payment made by the Agent to acquire
(discount) for its own account prior to maturity thereof any
acceptance created under a Letter of Credit.

     (v)  The Company shall be irrevocably and unconditionally
obligated forthwith to reimburse the Agent for the account of each
Bank for any amount paid by the Agent or such Bank upon any drawing
under any Letter of Credit, without presentment, demand, protest or
other formalities of any kind all of which are hereby expressly waived
by the Company. Each drawing under any Letter of Credit shall bear
interest at the Post-Default Rate until the Company shall have made
reimbursement for such drawing. If the Company shall fail to make
reimbursement for any such drawing prior to noon on the second
Business Day after such notice is given, the Agent may in its
discretion and without the consent of (but with concurrent notice to)
the Company effect such reimbursement of any Letter of Credit, subject
to the satisfaction of the conditions in SECTION 7 of the Revolving
and Term Credit Agreement and to the existence of Revolving
Commitments, by borrowing of Revolving Loans and the application of
the proceeds thereof to the related Reimbursement Obligations.  The
Reimbursement Obligations shall survive the Termination Date and the
termination of this Agreement. The Agent will pay to each Bank such
Bank's Commitment Percentage of all amounts received from the Company
for application in payment, in whole or in part, of the Reimbursement
Obligation in respect of any Letter of Credit, but only to the extent
such Bank has made payment to the Agent in respect of such Letter of
Credit pursuant to CLAUSE (iv) above. Nothing herein shall be deemed to
require the Agent to pay to any Bank any part of the proceeds of
disposition (rediscount) by the Agent for its own account to any other
Person of any acceptance created under a Letter of Credit which is
acquired (discounted) by the Agent prior to the maturity thereof or to
require any Bank to reimburse the Agent for the consequences of the
Agent's own gross negligence or willful misconduct.

     (vi) The obligations of the Company to pay Reimbursement
Obligations under this Agreement shall be absolute, unconditional and
irrevocable and shall be paid or performed strictly in accordance with
the terms of this Agreement under all circumstances whatsoever, 
including, without limitation, the following circumstances:

          (a)  any lack of legality, validity, regularity or
enforceability of this Agreement, any Letter of Credit, any

rights which the Company may have at any time against any beneficiary
or any transferee of any Letter of Credit (or any Persons or entities
for which such beneficiary or any such transferee may be acting), the
Agent, any Bank or any other Person, whether in connection with this
Agreement, any Letter of Credit, any Application or any agreement or
document related to any of the foregoing, the transactions
contemplated hereby or any unrelated transaction;

          (d)  any statement, certificate, draft or any other document
presented under any Letter of Credit proves to have been forged,
fraudulent, invalid or insufficient in any respect or any statement
therein proves to have been untrue or inaccurate in any respect
whatsoever;

          (e)  payment by the Agent under any Letter of Credit against
presentation of a draft or certificate which appears on its face to
comply but does not in fact comply with the terms of such Letter of
Credit;

          (f)  any defense based upon the failure of any beneficiary
or any transferee to receive all or any part of the proceeds of a draw
under any Letter of Credit transmitted by the Agent, or any
non-application or misapplication by any beneficiary or other
transferee of the proceeds of demand for payment under any Letter of
Credit; and

          (g)  any bankruptcy, insolvency, reorganization,
arrangement, assignment for the benefit of creditors, readjustment of
debt, dissolution, liquidation or other similar event with respect to
the Company.

PROVIDED, that no such payment shall impair any claim the Company may
have against the Agent or any Bank.

     (c)  ILLEGALITY. In the event that any restriction or limitation
is imposed upon or determined or held to be applicable to the Agent,
any Bank or the Company by, under or pursuant to any Legal
Requirement, which in the reasonable judgment of the Agent or any Bank
would prevent the Agent or such Bank from legally incurring liability
under or in respect of a Letter of Credit issued or proposed to be
issued hereunder, then the Agent shall give prompt written notice
thereof to the Company, whereupon the Agent and the Bank or Banks
affected shall have no obligation to issue or purchase participations
in any such Letter of Credit.

     2.2  AVAILABLE AMOUNT

          (a)  Concurrently with the delivery of each Independent
Engineering Report and related Coverage Report required or permitted
hereby, there shall be determined, based on the Most

                                 -31-


Recent Engineering Report and Approved Assumptions, the total maximum
amount of Revolving Loans and Letters of Credit to be available to the
Company hereunder without violation of the Required Ratios. Upon each
such delivery, the Company may by notice to the Co-Agents designate as
the Available Amount any amount (not to exceed $50,000,000) equal to
or less than such total maximum amount. The Available Amount so
designated shall remain in effect as the Available Amount until the
next determination under this SECTION 2.2. If no different amount is
designated in accordance with this SECTION 2.2, the Available Amount
shall be the lesser of (a) the Preliminary Available Amount then in
effect or (b) such total maximum amount.

          (b)  Notwithstanding anything herein to the contrary, (1) no
Bank shall be required to have aggregate Letters of Credit Liabilities
at any one time outstanding in excess of such Bank's Commitment
Percentage of the lesser of (x) $15,000,000 and (y) the difference
between (i) the Available Amount and (ii) the aggregate Revolving
Loans, and (2) if a Bank fails to participate in a Letter of Credit as
and when required hereunder and the Company subsequently makes a
repayment on the Reimbursement Obligations with respect to such Letter
of Credit, such repayment shall be split among the non-defaulting
Banks ratably in accordance with their respective Commitment
Percentages until each Bank has its Commitment Percentage of all of
the outstanding Reimbursement Obligations, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages.

          (c)  Notwithstanding anything in this Agreement to the
contrary, the Agent shall not be required to issue any Letter of
Credit during the existence of an Engineering Shortfall.

          (d)  The Company may from time to time at its option,
exercisable by giving written notice to the Co-Agents not more often
than once in any Calculation Period, provide to the Co-Agents an
Independent Engineering Report.  Upon the receipt of such notice, the
Co-Agents shall consult with the Company to determine new Approved
Assumptions, which shall be furnished to the Banks by a notice as
provided in the definition of "Approved Assumptions" and shall be
subject to the proviso therein. The Optional Reserve Report shall be
based on the new Approved Assumptions and shall be accompanied by a
Coverage Report as of the date such Report is furnished. The Annual
Debt Service Coverage Ratio, the Alternate Annual Debt Service
Coverage Ratio and the Life-of-Reserves Coverage Ratio shall each be
redetermined in accordance with this Agreement on the basis of each
such Optional Reserve Report and Coverage Report, and the Available
Amount recalculated as provided in this SECTION 2.2.

                                 -32-

          (e)  Notwithstanding any other provision of this Agreement
to the contrary, should both (x) the Company at any time designate as
the Available Amount an amount less than the maximum amount then
offered to it as the Available Amount by the Co-Agents and (y) as a
result the Company shall obtain the release of any Mortgaged
Properties under the Revolving and Term Credit Agreement, the
Available Amount may never thereafter exceed the amount so designated
by the Company.

     2.3  REDUCTIONS AND CHANGES OF COMMITMENTS.

     (a)  MANDATORY. On the Termination Date the aggregate Commitments
shall be terminated in their entirety.

     (b)  THE COMPANY'S OPTION. The Company shall have the right to
terminate or reduce the unused portion of the Commitments at any time
or from time to time; PROVIDED that: (i) the Company shall give notice
of each such termination or reduction to the Agent as provided in
SECTION 5.5; (ii) each such partial reduction shall be in minimum
increments equal to $5,000,000; and (iii) the Company may not cause
the Available Amount to be less than the aggregate principal amount of
the Revolving Loans then outstanding plus the Letter of Credit
Liabilities then outstanding. Any voluntary reduction in the Available
Amount prior to any scheduled reduction in the Available Amount shall
not affect the Available Amount after such scheduled reduction date
unless such voluntarily reduced Available Amount is less than the
amount scheduled to be the Available Amount after such scheduled
reduction date, in which case the Available Amount after such
scheduled reduction date shall be no greater than such voluntarily
reduced Available Amount.

     2.4  SEVERAL OBLIGATIONS. The failure of any Bank to participate
in any Letter of Credit shall not relieve any other Bank of its
obligation to participate in any Letter of Credit (the face amount of
which shall be reduced dollar for dollar by the amount of the share of
the Bank that failed to participate in such Letter of Credit) on such
date, but neither the Agent nor any Bank shall be responsible for the
failure of any other Bank to participate in any Letter of Credit.

     2.5  FEES. In consideration of the Commitments, the Company shall
pay to the Agent for the account of each Bank in accordance with its
Commitment Percentage commitment fees (the "COMMITMENT FEES") for the
period from the date of the execution of this Agreement to and
including the earlier of the date the Commitments are terminated or
the Termination Date at a rate per annum equal to 1/2% of the Unused
Commitment. The Company shall be entitled to credit on the Commitment
Fees any amount paid pursuant to SECTION 2.3 of the Revolving and Term
Credit Agreement. The Commitment Fees shall be computed for each day
and shall be based on the Unused Commitment for such day. Accrued
Commitment Fees shall be payable in arrears on the date of the initial
Letter of
                                 -33-


Credit, within three days after demand therefor on or about the
Quarterly Dates, and within three days after demand therefor on or
about the Termination Date. All past due Commitment Fees shall bear
interest at the Post-Default Rate. Upon receipt, the Agent shall
disburse the Commitment Fees to the Banks in accordance with their
Commitment Percentages.

     Section 3.     PREPAYMENTS.

     3.1  (a)  COMMITMENT AMOUNT.  The Company shall from time to time
on demand by the Agent prepay the Revolving Loans or reduce Letter of
Credit Liabilities in such amounts as shall be necessary so that at
all times the aggregate outstanding principal amount of all Revolving
Loans and all Letter of Credit Liabilities hereunder shall not be in
excess of the aggregate of the Revolving Commitments and the
Commitments. Any such payment shall be allocated between Revolving
Loans, Letter of Credit Liabilities (and if to Letter of Credit
Liabilities, first, to Reimbursement Obligations) and other
obligations as the Company may elect.

     (b) AVAILABLE AMOUNT. The Company shall from time to time on
demand by the Agent and on the Termination Date prepay the Revolving
Loans or reduce Letter of Credit Liabilities in such amounts as shall
be necessary so that at all times the aggregate outstanding principal
amount of all Revolving Loans and all Letter of Credit Liabilities of
the Company hereunder shall be less than or equal to the Available
Amount. Any such payment shall be allocated between Revolving Loans,
Letter of Credit Liabilities (and if to Letter of Credit Liabilities,
first, to Reimbursement Obligations) and other obligations as the
Company may elect.

     Section 4.     PAYMENTS OF PRINCIPAL AND INTEREST.

     4.1  REPAYMENT OF REIMBURSEMENT OBLIGATIONS. The Company will pay
to the Agent for the account of each Bank the amount of each
Reimbursement Obligation forthwith upon its incurrence. The amount of
any Reimbursement Obligation may, if the applicable conditions
precedent specified in SECTION 7 of the Revolving and Term Credit
Agreement have been satisfied, be paid with the proceeds of Revolving
Loans.

     4.2  INTEREST.  Subject to SECTION 12.8, the Company will pay to
the Agent for the account of each Bank interest on the unpaid
principal amount of each Reimbursement Obligation owed to such Bank
for the period commencing on the date such Reimbursement Obligation
arises to but excluding the date such Reimbursement Obligation shall
be paid in full, at the Post-Default Rate.

     Accrued interest shall be due and payable from time to time on
demand of the Agent or the Required Banks (through the Agent).

                                 -34-


     Section 5. PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     5.1  PAYMENTS. (a) Except to the extent otherwise provided
herein, all payments of principal of or interest on the Reimbursement
Obligations and other amounts to be made by the Company hereunder
shall be made in dollars, in immediately available funds, to the Agent
at its Principal Office (or in the case of a Successor Agent, at the
principal office of such successor Agent in the United States), not
later than 11:00 a.m. on the date on which such payment Shall become
due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding Business Day).

     (b) The Company shall, at the time of making each payment
hereunder, specify to the Agent the Reimbursement Obligations or other
amounts payable by the Company hereunder to which such payment is to
be applied (and in the event that it fails so to specify, such payment
shall be applied as the Agent may designate to the amounts then due
and payable); PROVIDED that if no Reimbursement Obligations are then
due and payable or an Event of Default has occurred and is continuing,
the Agent may apply such payment to the Obligations in such order as
it may elect in its sole discretion, but subject to the other terms
and conditions of this Agreement, including SECTION 5.2). Each payment
received by the Agent hereunder for the account of a Bank shall be
paid promptly to such Bank, in immediately available funds for the
account of such Bank's Applicable Lending Office.

     (c) If the due date of any payment hereunder falls on a day which
is not a Business Day, the due date for such payment shall be extended
to the next succeeding Business Day and interest shall be payable for
any principal so extended for the period of such extension.

     5.2  PRO RATA TREATMENT.  Except to the extent otherwise provided
herein, (a) each issuance of a Letter of Credit and each termination
or reduction of the Commitments of the Banks under SECTION 2.3 shall
be made PRO RATA according to the Banks' respective Commitments;
(b) each payment by the Company of principal of or interest on any
Reimbursement Obligation shall be made to the Agent for the account of
the Banks PRO RATA in accordance with the respective unpaid principal
amounts of such Reimbursement Obligation held by the Banks; and (c)
the Banks (other than the Agent) shall purchase from the Agent
participations in the Letters of Credit in accordance with their
respective Commitment Percentages.

     5.3  COMPUTATIONS. Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees
hereunder, will be computed on the basis of 365 (or 366) days and
actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable. All other interest

                                 -35-



shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring
in the period for which payable, unless the effect of so computing
shall be to cause the rate of interest to exceed the Highest Lawful
Rate (in which event interest shall be calculated on the basis of the
actual number of days elapsed in a year composed of 365 or 366 days,
as the case may be).

     5.4 MINIMUM AND MAXIMUM AMOUNTS. Each Letter of Credit shall be
in a face amount at least equal to $100,000.

     5.5 CERTAIN ACTIONS, NOTICES, ETC. Notices to the Agent of any
termination or reduction of Commitments, prepayments under SECTION 3.1
and requests for the issuance of Letters of Credit shall be
irrevocable and shall be effective only if received by the Agent not
later than 11:00 a.m. on the number of Business Days prior to the date
of the relevant issuance, termination, reduction, and/or prepayment
specified below:
                              Number of Business
                                  Days Prior
                                    Notice
Termination or reduction
of Commitments                        10

Issuance of Letters of Credit          5

Prepayments                            1


Each such notice of termination or reduction shall specify the amount
of the Commitments to be terminated or reduced. Each such notice of
prepayment shall specify the amount to be prepaid (subject to SECTION
3.1) and the date of prepayment (which shall be a Business Day). The
Agent shall promptly notify the Banks of the contents of each such
notice or Application.  Notice of any prepayment having been given,
the principal amount specified in such notice, together with interest
thereon to the date of prepayment, shall be due and payable on such
prepayment date.

     5.6  NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Agent shall
have been notified by a Bank prior to noon on the date on which such
Bank is to make payment to the Agent of any amount to be paid by such
Bank to reimburse the Agent for a drawing under any Letter of Credit
or by the Company prior to the date on which the Company is to make a
payment to the Agent for the account of one or more of the Banks, as
the case may be (such Bank or the Company being herein called the
"PAYOR" and such payment being herein called the "REQUIRED PAYMENT"),
which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to the Agent, the Agent may assume
that the Required Payment has been made and may, in reliance upon such
assumption
                                 -36-


(but shall not be required to), make the amount thereof available to
the intended recipient on the date that such Required Payment is to be
made. If the Payor is the Company and the Company has not in fact made
the Required Payment to the Agent on or before such date, the
recipient of such payment (or, if the recipient is the beneficiary of
a Letter of Credit, the Company, and, if the Company fails to pay the
amount thereof to the Agent on demand, then the Banks, to the extent
not already paid, ratably in proportion to their respective Commitment
Percentages) shall, on demand, pay to the Agent the amount made
available by the Agent, together with interest thereon from the date
such amount was so made available by the Agent until the date the
Agent recovers such amount at a rate per annum equal to the Fed Funds
Rate for the first three days and thereafter at the Fed Funds Rate
plus 2%. If the Payor is a Bank and such Bank has not in fact made the
Required Payment to the Agent on or before such date, then such Bank
shall pay to the Agent the amount made available by the Agent on
behalf of such Bank, together with interest thereon from the date such
amount was so made available by the Agent until the Agent recovers
such amount at a rate per annum equal to the Fed Funds Rate for the
first three days and thereafter at the Fed Funds Rate plus 2%.

     5.7 SHARING OF PAYMENTS, ETC. If a Bank or any participant of a
Bank shall obtain payment of any obligation to it under this
Agreement, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, then such Bank or
participant shall promptly purchase from the other Banks
participations in the Reimbursement Obligations or other obligations
held by the other Banks in such amounts, and make such other
adjustments from time to time as shall be equitable to the end that
all the Banks and participants shall share the benefit of such payment
(net of any expenses which may be incurred by such Bank or its
participant in obtaining or preserving such benefit) PRO RATA in
accordance with the unpaid principal and interest on such obligations
then due to each of them. To such end all the Banks and their
participants shall make appropriate adjustments among themselves (by
the resale of participations sold or otherwise) if such payment is
rescinded or must otherwise be restored.  The Company agrees, to the
fullest extent it may effectively do so under applicable law, that any
Bank so purchasing a participation in the Reimbursement Obligations or
other obligations held by other Banks may exercise all rights of
set-off, bankers' lien, counterclaims or similar rights with respect
to such participation as fully as if such Bank were a direct holder of
Reimbursement Obligations or other obligations in the amount of such
participation. Nothing contained herein shall require any Bank to
exercise any such right or shall affect the right of any Bank to
exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Company.

                                 -37-


     5.8  OTHER EXPENSES. The Company agrees to pay the Agent, for the
account of the Agent, the usual and customary charges of TCB for each
extension, amendment and wire advice of and drawing under the Letters
of Credit.

     Section 6.  YIELD PROTECTION AND ILLEGALITY.

     6.1  ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. If as a
result of any Regulatory Change there shall be imposed, modified or
deemed applicable any tax, reserve, special deposit or similar
requirement against or with respect to or measured by reference to
Letters of Credit issued or to be issued hereunder and the result
shall be to increase the cost to the Agent or any Bank of issuing or
maintaining or participating in any Letter Of Credit or reduce any
amount receivable by the Agent or any Bank hereunder in respect of any
Letter of Credit or participation therein, then such Bank shall notify
the Company through the Agent, and upon demand therefor by such Bank
through the Agent, the Company (subject to SECTION 12.8) shall pay to
the Agent or such Bank, from time to time as specified by the Agent or
such Bank, such additional amounts as shall be sufficient to
compensate the Agent or such Bank for such increased costs or
reductions in amount. Before making such demand pursuant to this
SECTION 6.1, the Agent or such Bank will designate a different
available Applicable Lending Office for the Letter of Credit or
participation or take such other action as the Company may request, if
such designation or action will avoid the need for, or reduce the
amount of, such compensation and will not, in the sole opinion of the
Agent or such Bank, be disadvantageous to the Agent or such Bank. A
statement as to such increased costs or reductions in amount incurred
by the Agent or such Bank, submitted by the Agent or such Bank to the
Company, shall cover amounts accruing under this section with respect
to a period beginning not earlier than 120 days from the date thereof
and be conclusive as to the amount thereof, absent manifest error.

     In the event any Bank shall seek compensation pursuant to this
SECTION 6.1, the Company may give notice to such Bank (with copies to
the Agent) that it wishes to seek one or more Eligible Assignees
(which may be one or more of the Banks) to assume the Commitment of
such Bank and to purchase and assume its outstanding Letter of Credit
Liabilities. Each Bank requesting compensation pursuant to this
SECTION 6.1 agrees to sell its Commitment and interest in this
Agreement and in the Obligations and in the Revolving and Term Credit
Agreement pursuant to SECTION 12.6 (without recourse, representation
or warranty except as provided in SECTION 12.6) to any such Eligible
Assignee for an amount equal to the sum of the outstanding unpaid
principal of and accrued interest on such Obligations plus all other
fees and amounts (including any compensation claimed by such Bank
under this SECTION 6.1) owing to such Bank hereunder and under the
Revolving and Term Credit Agreement calculated, in each case, to the
date such Commitment, Obligations and interests are purchased,
whereupon such Bank shall

                                 -38-


have no further Commitment or other obligation to the Company
hereunder or under the Revolving and Term Credit Agreement.

     6.2  CAPITAL ADEQUACY. If any Bank shall have determined that the
adoption after the date hereof or effectiveness after the date hereof
(regardless of whether previously announced) of any applicable Legal
Requirement or treaty regarding capital adequacy, or any change after
the date hereof in any existing or future Legal Requirement or treaty
regarding capital adequacy, or any change in the interpretation or
administration thereof after the date hereof by any Governmental
Authority or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive after the date hereof
regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority or comparable agency has or would have
the effect of reducing the rate of return on the capital of such Bank
(or any holding company of which such Bank is a part) as a consequence
of its obligations hereunder and under or in respect of the Letters of
Credit to a level below that which such Bank or holding company could
have achieved but for such adoption, change or compliance by an amount
deemed by such Bank to be material, then from time to time, upon
demand by such Bank (with a copy to the Agent), the Company (subject
to SECTION 12.8) shall pay to such Bank such additional amount or
amounts as will compensate such Bank or holding company for such
reduction. The certificate of any Bank setting forth such amount or
amounts as shall be necessary to compensate it and the basis therefor
shall cover amounts accruing under this SECTION 6.2 with respect to a
period beginning not earlier than 120 days from the date thereof and
shall be conclusive and binding, absent manifest error. The Company
shall pay the amount shown as due on any such certificate upon
delivery of such certificate.  In preparing such certificate, a Bank
may employ such assumptions and allocations of costs and expenses as
it shall in good faith deem reasonable and may use any reasonable
averaging and attribution method. In the event any Bank shall seek
compensation pursuant to this SECTION 6.2, the Company may give notice
to such Bank (with copies to the Agent) that it wishes to seek one or
more Eligible Assignees (which may be one or more of the Banks) to
assume the Commitment of such Bank and to purchase and assume its
outstanding Letter of Credit Liabilities. Each Bank requesting
compensation pursuant to this SECTION 6.2 agrees to sell its
Commitment and interest in this Agreement and in the Obligations and
in the Revolving and Term Credit Agreement pursuant to SECTION 12.6
(without recourse, representation or warranty except as provided in
SECTION 12.6) to any such Eligible Assignee for an amount equal to the
sum of the outstanding unpaid principal of and accrued interest on
such Obligations plus all other fees and amounts (including any
compensation claimed by such Bank under this SECTION 6.2) owing to
such Bank hereunder and under the Revolving and Term Credit Agreement
calculated, in each case, to the date such Commitment, Obligations,
and interests are purchased, whereupon such Bank shall

                                 -39-


have no further Commitment or other obligation to the Company
hereunder or under the Revolving and Term Credit Agreement.

is duly organized, validly existing and in good standing under the

which it is subject, or constitute a default under any such agreement
or instrument.

the Credit Documents by the Company have been duly authorized by all

provisions would result in a Material Adverse Change. (b) The Company
has no knowledge of any event with respect to each Plan which could
result in a Material Adverse Change.

Registration Statement, the Company and its Subsidiaries, and the
plants and sites of each, have complied with all Applicable

comply would not result in a Material Adverse Change. Without limiting
the generality of the preceding sentence, neither the Company nor any
of its Subsidiaries has received notice of or has actual knowledge of
any actual or claimed or asserted failure so to comply with Applicable
Environmental Laws or of any other Environmental Claim which alone or

any other applicable Legal Requirement, or in a manner which would
result in an Environmental Claim except where such noncompliance or
liability or Environmental Claim would not result in a Material
Adverse Change.  The representation and warranty contained in this
SECTION 8.13 is based in its entirety upon (a) current interpretations

    Section 11.     THE AGENT.

    11.1  APPOINTMENT, POWERS AND IMMUNITIES.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its Agent
under the Credit Documents and under the Letters of Credit with such
powers as are specifically delegated to the Agent by the terms
thereof, together with such other powers as are reasonably incidental
thereto. The Agent (which term as used in this SECTION 11 shall
include reference to its Affiliates and its own and its Affiliates'
officers, directors, employees and agents) shall (a) have no duties or
responsibilities except those expressly set forth in the Letters of
Credit and the Credit Documents, and shall not by reason of any Credit
Document be a trustee or fiduciary for any Bank; (b) not be
responsible to any Bank for any recitals, statements, representations
or warranties contained in any Credit Document, or in any certificate
or other document referred to or provided for in, or received by any
of them under, any Credit Document, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of any
Credit Document or any other document referred to or provided for
therein or any property covered thereby or for any failure by the
Company or any other Person to perform any of its obligations
thereunder; (c) not be required to initiate or conduct any litigation
or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and SECTION 11.7
shall apply), and (d) not be responsible for any action taken or
omitted to be taken by it under any Credit Document or any other
document or instrument referred to or provided for therein or in
connection therewith, including pursuant to its own negligence, except
for its own gross negligence or willful misconduct. The Agent may
employ agents and attorneys-in-fact and shall not be responsible for
the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. Without in any way limiting any
of the foregoing, each Bank acknowledges that the Agent shall have no
greater responsibility in the operation of the Letters of Credit than
is specified in the Uniform Customs and Practice of Documentary
Credits (1983 Revision, International Chamber of Commerce Publication
No. 400).

    11.2  RELIANCE BY AGENT.  The Agent shall be entitled to rely upon
any certification, notice or other communication (including any
thereof by telephone, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of
the proper Person or Persons, and upon advice and statements of legal
counsel (which may be counsel for the Company), independent
accountants and other experts selected by the Agent. As to any matters
not expressly provided for by any Credit Document, the Agent shall in
all cases be fully protected in acting, or in refraining from acting,
hereunder and thereunder in accordance with instructions of the
Required Banks, and any action taken or failure to act pursuant
thereto shall be binding on all of the Banks.

                                -67-

     11.3  DEFAULTS.  The Agent shall not be deemed to have knowledge
of the occurrence of a Default (other than the non-payment of
principal of or interest on Reimbursement Obligations) unless it has
received notice from a Bank or the Company specifying such Default and
stating that such notice is a "Notice of Default". In the event that
the Agent receives such a notice of the occurrence of a Default, the
Agent shall give prompt notice thereof to the Banks (and shall give
each Bank prompt notice of each such non-payment). The Agent shall
(subject to SECTIONS 11.7 and 12.5) take such action with respect to
such Default as shall be directed by all Banks or the Required Banks,
as appropriate, and within its rights under the Credit Documents and
at law or in equity; PROVIDED that, unless and until the Agent shall
have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action,
permitted hereby with respect to such Default as it shall deem
advisable in the best interests of the Banks and within its rights
under the Credit Documents, at law or in equity.
    
    11.4  RIGHTS AS A BANK.  With respect to their Commitments, the
Letters of Credit and the Reimbursement Obligations, TCB and
NationsBank in their capacities as Banks hereunder shall have the same
rights and powers hereunder as any other Bank and may exercise the
same as though they were not acting as the Agent or the Co-Agents, and
the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent and the Co-Agents in their individual
capacity.  The Agent and the Co-Agents may (without having to account
therefor to any Bank) accept deposits from, lend money to and
generally engage in any kind of banking, trust, letter of credit,
agency or other business with the Company (and any of its Affiliates)
as if they were not acting as the Agent and the Co-Agents, and the
Agent and the Co-Agents may accept fees and other consideration from
the Company and its Affiliates (in addition to the fees heretofore
agreed to between the Company and the Agent or the Co-Agents) for
services in connection with this Agreement or otherwise without having
to account for the same to the Banks.

    11.5  INDEMNIFICATION.  The Banks agree to indemnify the Agent (to
the extent not reimbursed under SECTION 12.3 or 12.4, but without
limiting the obligations of the Company under said SECTIONS 12.3 and
12.4), ratably in accordance with their respective Commitments, for
any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever (including the consequences of the
negligence of the Agent) which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of
any Credit Document or any other documents contemplated by or referred
to therein or the transactions contemplated thereby (including the
costs and expenses which the Company is obligated to pay under
SECTIONS 12.3 and 12.4 but excluding, unless a Default has occurred
and is continuing, normal administrative costs and expenses incident
to the performance of

                                 -68-


its agency duties hereunder) or the enforcement of any of the terms
hereof or thereof or of any such other documents, including the
negligence of the Agent; PROVIDED that no Bank shall be liable for any
of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the party to be indemnified. The obligations of
the Banks under this SECTION 11.5 shall survive the termination of
this Agreement.

    11.6  NON-RELIANCE ON THE AGENT AND OTHER BANKS.  Each Bank agrees
that it has received current financial information with respect to the
Company and that it has, independently and without reliance on the
Co-Agents or any other Bank and based on such documents and
information as it has deemed appropriate, made its own credit analysis
of the Company and decision to enter into this Agreement and that it
will, independently and without reliance upon the Co-Agents or any
other Bank, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Credit Documents.
The Co-Agents shall not be required to keep themselves informed as to
the performance or observance by the Company of any Credit Document or
any other document referred to or provided for therein or to inspect
the property or books of the Company or any other Person. Except for
notices, reports and other documents and information expressly
required to be furnished to the Banks by the Co-Agents under the
Credit Documents, the Co-Agents shall not have any duty or
responsibility to provide any Bank with any credit or other
information concerning the affairs, financial condition or business of
the Company (or any of its Affiliates) which may come into the
possession of the Co-Agents.
    
    11.7  FAILURE TO ACT.  Except for action expressly required of the
Agent under the Credit Documents, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder
unless it shall receive further assurances to its satisfaction by the
Banks of their indemnification obligations under SECTION 11.5 against
any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

    11.8  RESIGNATION OR REMOVAL OF THE AGENT.  Subject to the
appointment and acceptance of a successor Agent as provided below, the
Agent may resign at any time by giving notice thereof to the Banks and
the Company, and the Agent may be removed at any time with or without
cause by the Required Banks.  Upon any such resignation or removal,
the Required Banks shall have the right to appoint a successor Agent.
If no successor Agent shall have been so appointed by the Required
Banks and shall have accepted such appointment within 30 days after
the retiring Agent's giving of notice of resignation or the Required
Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent. Any successor Agent
shall be a bank which has an office in the United States and a
combined

                                -69-


capital and surplus of at least $250,000,000 and with its deposits
insured by the FDIC. Upon the acceptance of any appointment as the
Agent hereunder 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 hereunder. Such
successor Agent shall promptly specify its Principal Office referred
to in SECTIONS 3.1 and 5.1 by notice to the Company. After any
retiring Agent's resignation or removal hereunder as the Agent, the
provisions of this SECTION 11 shall continue in effect for its benefit
in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent.

    Section 12.  MISCELLANEOUS.

    2.1  WAIVER.  No waiver of any Default shall be a waiver of any
other Default. No failure on the part of the Agent or any Bank to
exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Credit Document
shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any
other or further exercise thereof or the exercise of any other right,
power or privilege. The remedies provided in the Credit Documents are
cumulative and not exclusive of any remedies provided by law or in
equity.

   12.2  NOTICES.  All notices and other communications provided for
herein (including any modifications of, or waivers or consents under,
this Agreement) shall be given or made by telex, telegraph, telecopy
(confirmed by mail), cable or other writing and telexed, telecopied,
telegraphed, cabled, mailed or delivered to the intended recipient at
the "Address for Notices" specified below its name on the signature
pages hereof; or, as to any party, at such other address as shall be
designated by such party in a notice to the Company and the Agent
given in accordance with this Section. Except as otherwise provided in
this Agreement, all such communications shall be deemed to have been
duly given when transmitted by telex or telecopier, delivered to the
telegraph or cable office or personally delivered or, in the case of a
mailed notice, upon receipt, in each case given or addressed as
aforesaid.
    
    12.3  EXPENSES, ETC.  Whether or not any Letter of Credit is ever
issued, the Company shall pay or reimburse on demand each of the Banks
and the Co-Agents for paying:  (a) the reasonable fees and expenses of
Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P., special counsel to the
Agent, in connection with (1) the preparation, execution and delivery
of the Credit Documents (including the exhibits and schedules hereto),
the issuance of the Letters of Credit hereunder and (2) any
modification, supplement or waiver of any of the terms of any Credit
Document; (b) all reasonable out-of-pocket costs and expenses of the
Banks and the Co-Agents (including reasonable counsels' fees) in
connection with
                                -70-


any Event of Default under or the enforcement of any Credit Document;
(c) all transfer, stamp, documentary or other similar taxes,
assessments or charges levied by any governmental or revenue authority
in respect of any Credit Document or any other document referred to
therein; and (d) reasonable expenses of due diligence and syndication,
and mutually agreed advertising and marketing costs.

    12.4  INDEMNIFICATION.  The Company shall indemnify the Agent
(including the Agent when acting as issuer of the Letters of Credit),
the Co-Agents, the Banks, and each Affiliate thereof and their
respective directors, officers, employees, agents and counsel from,
and hold each of them harmless against, any and all losses,
liabilities, costs, expenses, claims or damages to which any of them
may become subject, regardless of and including losses arising from
the negligence of the Agent or the Co-Agents or the Banks or any other
indemnitee, (A) in connection with the execution and delivery or
transfer of or payment or failure to pay under any Letter of Credit,
including, without limitation, any claims, damages, losses,
liabilities, costs or expenses which the Agent, such Co-Agent or such
Bank, as the case may be, may incur (whether incurred as a result of
its own negligence or otherwise) by reason of or in connection with
the failure of any other Bank (whether as a result of its own
negligence or otherwise) to fulfill or comply with its obligations to
the Agent or such Bank, as the case may be, hereunder (but nothing
herein contained shall affect the rights the Company may have against
such defaulting Bank); and (B) insofar as such losses, liabilities,
costs, expenses, claims or damages arise out of or result from any (a)
actual or proposed use by the Company of the proceeds of any extension
of credit by the Agent or any Bank hereunder; (b) breach by the
Company of any Credit Document; (c) violation by the Company or any of
its Subsidiaries of any Legal Requirement including Applicable
Environmental Laws; (d) any Bank's or the Agent's or any Co-Agent's
being deemed an owner or operator of any assets of the Company or its
Subsidiaries by a court or other regulatory or administrative agency
or tribunal in circumstances in which neither the Agent, either
Co-Agent nor any of the Banks is generally operating or generally
exercising control over such assets, to the extent such losses,
liabilities, claims or damages arise out of or result from any Legal
Requirement including Applicable Environmental Laws pertaining to the
condition of such assets, (e) Environmental Claim or (f)
investigation, litigation or other proceeding (including any
threatened investigation or proceeding) relating to any of the
foregoing, and the Company shall reimburse the Agent, Co-Agent, each
Bank, and each Affiliate thereof and their respective directors,
officers, employees, agents and counsel, upon demand, for any expenses
(including reasonable legal fees) incurred in connection with any such
investigation or proceeding; but excluding any such losses,
liabilities, claims, damages, costs or expenses incurred by a Person
or any Affiliate thereof or their respective directors, officers,
employees, agents or counsel by reason of the gross negligence or
willful misconduct                                
                                 -71-


of such Person, Affiliate director, officer, employee, agent or
counsel.  The obligation of the Company to provide indemnification
under this SECTION 12.4 for fees and expenses of counsel shall be
limited to the fees and expenses of one counsel in each jurisdiction
representing all of the Persons entitled to such indemnification,
except to the extent that, in the reasonable judgment of any such
indemnified Person, the existence of actual or potential conflicts of
interest make representation of all of such indemnified Persons by the
same counsel inappropriate; in such a case, the Person exercising such
judgment shall be indemnified for the reasonable fees and expenses of
its separate counsel to the extent provided in this SECTION 12.4
without giving effect to the first clause of this sentence.  Nothing
in this SECTION 12.4 is intended to limit the obligations of the
Company under any other provision of this Agreement.

    12.5  AMENDMENTS, ETC.  No amendment or waiver of any provision of
any Credit Document, nor any consent to any departure by the Company
therefrom, shall in any event be effective unless the same shall be
agreed or consented to by the Required Banks and the Company, and each
such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; PROVIDED that
no amendment, waiver or consent shall, unless in writing and signed by
each Bank affected thereby, (a) increase the Commitment of any of the
Banks or subject the Banks to any additional obligations; (b) reduce
the principal of, or interest on, any Reimbursement Obligation, fee or
other sum to be paid under any Credit Document; (c) postpone any
scheduled date fixed for any payment of principal of, or interest on,
any Reimbursement Obligation, fee or other sum to be paid under any
Credit Document; (d) change the percentage of any of the Commitments,
or of the aggregate unpaid principal amount of the Reimbursement
Obligations, or the number of Banks which shall be required for the
Banks or any of them to take any action under this Agreement; (e)
change any provision contained in SECTIONS 2.3, 5.2, 5.7, 6, 12.3 or
12.4 or this SECTION 12.5, or in the definition of "Required Ratios".
Anything in this SECTION 12.5 to the contrary, no amendment, waiver or
consent shall be made with respect to SECTION 11 without the consent
of the Agent and the Co-Agents.

    12.6  SUCCESSORS AND ASSIGNS. (a) This Agreement shall be binding
upon and inure to the benefit of the Company, the Agent, the Co-Agents
and the Banks and their respective successors and assigns.  The
Company may not assign or transfer any of its rights or obligations
hereunder without the prior written consent of all of the Banks.

    (b) Each Bank may sell participations to any Person in all or part
of its Reimbursement Obligation, or all or part of its Commitment, in
which event, without limiting the foregoing, the provisions of SECTION
6 shall inure to the benefit of each purchaser of a participation and
the PRO RATA treatment of

                                -72-


payments, as described in SECTION 5 2, shall be determined as if such
Bank had not sold such participation.  In the event any Bank shall
sell any participation, (1) the Company, the Agent, the Co-Agent and
the other Banks shall continue to deal solely and directly with such
selling Bank in connection with such selling Bank's rights and
obligations under the Credit Documents (including the Applications
held by such selling Bank); (2) such Bank shall retain the sole right
and responsibility to enforce the Reimbursement Obligations, including
the right to approve any amendment, modification or waiver of any
provision of this Agreement other than amendments, modifications or
waivers with respect to (A) any fees payable hereunder to the Banks,
and (B) the amount of principal or the rate of interest payable on, or
the dates fixed for the scheduled repayment of principal of, the
Reimbursement Obligations and other sums to be paid to the Banks
hereunder, and (3) the Company agrees, to the fullest extent it may
effectively do so under applicable law, that any participant of a Bank
may exercise all rights of set-off, bankers' lien, counterclaim or
similar rights with respect to such participation as fully as if such
participant were a direct holder of Reimbursement Obligations if such
Bank has previously given notice of such participation to the Company.

    (c) Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitment and
the same portion of the related Reimbursement Obligations at the time
owing to it); PROVIDED (1) other than in the case of an assignment to
a Person at least 50% owned by the assignor Bank, or by a common
parent of both, or to another Bank, the Agent and the Company must
give their respective prior written consent, which consent will not be
unreasonably withheld; (2) the aggregate amount of the Commitment
and/or Reimbursement Obligations of the assigning Bank subject to each
such assignment (determined as of the date the Assignment Agreement
with respect to such assignment is delivered to the Agent) shall in no
event be less than $750,000 (or $75,000 in the case of an assignment
between Banks) (except for certain exceptions approved by the Company
and the Agent) and shall be in an amount that is an integral multiple
of $75,000; (3) the assigning Bank shall contemporaneously assign to
such assignee Bank or Eligible Assignee an equal percentage of the
assigning Bank's Revolving Commitment and Term Loan Commitment and all
assigning Bank's other rights and obligations under the Revolving and
Term Credit Agreement; and (4) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and
recording in its records, an Assignment Agreement with blanks
appropriately completed, together with the Applications subject to
such assignment and a processing and recordation fee of $2,000 (for
which the Company shall have no liability except in the case of
assignments required by the Company pursuant to SECTION 6.1 or 6.2, in
which case such fee shall be paid by the Company). Upon such
execution, delivery, acceptance and recording, from and after the

                                -73-


effective date specified in each Assignment Agreement, (A) the
assignee thereunder shall be a party hereto and, to the extent
provided in such Assignment Agreement, have the rights and obligations
of a Bank hereunder and (B) the Bank thereunder shall, to the extent
provided in such assignment, be released from its obligations under
this Agreement (and, in the case of an Assignment Agreement covering
all or the remaining portion of an assigning Bank's rights and
obligations under this Agreement, such Bank shall cease to be a party
hereto).

    (d) By executing and delivering an Assignment Agreement, the Bank
assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows  (1) other
than the representation and warranty that it is the legal and
beneficial owner of the interest being assigned thereby, such assignor
Bank makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in
or in connection with any Credit Document or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of any
Credit Document; (2) such assignor Bank makes no representation or
warranty and assumes no responsibility with respect to the financial
condition of the Company or the performance or observance by the
Company of any of its obligations under any Credit Document; (3) such
assignee confirms that it has received a copy of this Agreement,
together with copies of the financial statements of the Company
previously delivered in accordance herewith and such other documents
and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment Agreement; (4)
such assignee will, independently and without reliance upon the Agent,
such assignor Bank or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make
its own credit decisions in taking or not taking action under the
Credit Documents; (5) such assignee appoints and authorizes the Agent
to take such action as agent on its behalf and to exercise such powers
under the Credit Documents as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental
thereto, and (6) such assignee agrees that it will perform in
accordance with their terms all obligations that by the terms of the
Credit Documents are required to be performed by it as a Bank.

    (e) The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and
addresses of the Banks and the Commitment of, and principal amount of
the Reimbursement Obligations owing to, each Bank from time to time.
The entries in such record shall be conclusive, in the absence of
manifest error, and the Company, the Agent and the Banks say treat
each Person the name of which is recorded therein as a Bank hereunder

                                -74-


Bank at any reasonable time and from time to time upon reasonable
prior notice.

    (f) Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the
Application subject to such assignment, the written consent to such
assignment and the fee payable in respect thereto, the Agent shall, if
such Assignment Agreement has been completed with blanks appropriately
filled, (1) accept such Assignment Agreement; (2) record the
information contained therein in its records, and (3) give prompt
notice thereof to the Company.

   (g) Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Company furnished to
such Bank by or on behalf of the Company.

   (h) Any assignment by a Bank pursuant to this SECTION 12.6 shall
not result in any single Bank holding in excess of 25% of the
aggregate of the Commitments at any one time.

   (i) Notwithstanding any other provision of this SECTION 12.6, TCB
and its Affiliates may not assign their rights hereunder unless, after
giving effect to such assignment, TCB and its Affiliates would have an
aggregate Commitment Percentage of at least 10%.

   (j) Notwithstanding anything herein to the contrary, each Bank may
pledge and assign all or any portion of its rights and interests under
the Credit Documents to any Federal Reserve Bank.

   12.7  SURVIVAL; TERM; REINSTATEMENT.  In addition to the other
provisions of this Agreement expressly stated to survive the
termination of this Agreement, the obligations of the Company under
SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7
and the obligations of the Banks under SECTION 12.8 shall survive the
termination of this Agreement. The term of this Agreement shall be
until (a) the full and final payment of all Reimbursement Obligations,
(b) the expiry of all Letters of Credit, (c) the termination of all
Commitments and (d) the payment of all amounts due under the Credit
Documents. The Company agrees that if at any time all or any part of
any payment previously applied by any Bank to any Reimbursement
Obligation or other sum hereunder is or must be returned by or
recovered from such Bank for any reason (including the order of any
bankruptcy court), the Credit Documents shall automatically be
reinstated to the same effect as if the prior application had not been
made, and the Company hereby agrees to indemnify such Bank against,
and to save and hold such Bank harmless from, any required return by
or recovery from such Bank of any such payment because of its being
deemed preferential under applicable Legal Requirements, or for any
other reason.

                                -75-

     12.8  LIMITATION OF INTEREST.  The parties to this Agreement
intend to strictly comply with all applicable laws, including
applicable usury laws. Accordingly, the provisions of this Section
shall govern and control over every other provision of any Credit
Document which conflicts or is inconsistent with this Section, even if
such provision declares that it controls. As used in this SECTION
12.8, the term "interest" includes the aggregate of all charges, fees,
benefits or other compensation which constitute interest under
applicable law; PROVIDED that, to the maximum extent permitted by
applicable law, (a) any non-principal payment shall be characterized
as an expense or as compensation for something other than the use,
forbearance or detention of money, and not as interest and (b) all
interest at any time contracted for, reserved, charged or received
shall be amortized, prorated, allocated and spread, in equal parts
during the full term of this Agreement and the Commitments. In no
event shall the Company or any other Person be obligated to pay, or
the Agent or any Bank have any right or privilege to reserve, receive
or retain, (x) any interest in excess of the maximum amount of
nonusurious interest permitted under the laws of the State of Texas or
the applicable laws (if any) of the United States or of any other
state or (y) total interest in excess of the amount which the Agent or
such Bank could lawfully have contracted for, reserved, received,
retained or charged had the interest been calculated for the full term
of this Agreement at the Highest Lawful Rate.  On each day, if any,
that the interest rate (the "Stated Rate") called for under any Credit
Document exceeds the Highest Lawful Rate, the rate at which interest
shall accrue shall automatically be fixed by operation of this
sentence at the Highest Lawful Rate for that day, and shall remain
fixed at the Highest Lawful Rate for each day thereafter until the
total amount of interest accrued equals the total amount of interest
which would have accrued if there were no such ceiling rate as is
imposed by this sentence. Thereafter, interest shall accrue at the
Stated Rate unless and until the Stated Rate again exceeds the Highest
Lawful Rate when the provisions of the immediately preceding sentence
shall again automatically operate to limit the interest accrual rate.
The daily interest rates to be used in calculating interest at the
Highest Lawful Rate shall be determined by dividing the applicable
Highest Lawful Rate per annum by the number of days in the calendar
year for which such calculation is being made. None of the terms and
provisions contained in any Credit Document which directly or
indirectly relate to interest shall ever be construed without
reference to this Section, or be construed to create a contract to pay
for the use, forbearance or detention of money at an interest rate in
excess of the Highest Lawful Rate. If the term of this Agreement is
shortened by reason of acceleration of maturity as a result of any
Default or by any other cause, or by reason of any required or
permitted prepayment, and if for that (or any other) reason the Agent
or any Bank at any time, including the stated maturity, is owed or
receives (and/or has received) interest in excess of interest
calculated at the Highest Lawful Rate, then and in any such event all
of any such excess interest shall be

                                -76-


canceled automatically as of the date of such acceleration, prepayment
or other event which produces the excess, and, if such excess interest
has been paid to the Agent or such Bank, it shall be credited PRO
TANTO against the then-outstanding principal balance of the Company's
obligations to the Agent or such Bank, effective as of the date or
dates when the event occurs which causes it to be excess interest,
until such excess is exhausted or all of such principal has been fully
paid and satisfied, whichever occurs first, and any remaining balance
of such excess shall be promptly refunded to its payor.

   12.9  CAPTIONS.  Captions and section headings appearing herein are
included solely for convenience of reference and are not intended to
affect the interpretation of any provision of this Agreement.

   12.10  COUNTERPARTS.  Each Credit Document may be executed in any
number of counterparts, all of which taken together shall constitute
one and the same agreement and any of the parties hereto may execute
such Credit Document by signing any such counterpart.

   12.11  GOVERNING LAW.  Except to the extent otherwise specified
therein, each Credit Document shall be governed by and construed in
accordance with the law of the State of Texas and the United States of
America. The Company hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Southern District of Texas
and of any Texas state court sitting in Harris County, Texas for
purposes of all legal proceedings arising out of or relating to the
Credit Documents or the transactions contemplated thereby The Company
irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the
venue of any such proceeding brought in such a court and any claim
that any such proceeding brought in such a court has been brought in
an inconvenient forum.

   12.12  SEVERABILITY.  Whenever possible, each provision of the
Credit Documents shall be interpreted in such manner as to be
effective and valid under applicable law. If any provision of any
Credit Document shall be invalid, illegal or unenforceable in any
respect under any applicable law, the validity, legality and
enforceability of the remaining provisions of such Credit Document
shall not be affected or impaired thereby.

   12.13  CHAPTER 15 NOT APPLICABLE.  Chapter 15 of the Texas Credit
Code shall not apply to any Credit Document or to any Commitment or
Letter of Credit or Application or Reimbursement Obligation, nor shall
any Credit Document be governed by or be subject to the provisions of
such Chapter 15 in any manner whatsoever.

                                -77-

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed and delivered on May 20, 1992 but effective as of
the day and year first above written.
