                           "until" each mean "to but excluding", and the word
                           "through" means "to and including."

                           (iv)  The term "property" includes any kind of
                           property or asset, real, personal or mixed, tangible
                           or intangible.

                  (d) Unless otherwise expressly provided herein, (i) references
         to agreements (including this Agreement) and other contractual
         instruments shall be deemed to include all subsequent amendments and
         other modifications thereto, but only to the extent such amendments and
         other modifications are not prohibited by the terms of any Loan
         Document, and (ii) references to any statute or regulation are to be
         construed as including all statutory and regulatory provisions
         consolidating, amending, replacing, supplementing or interpreting the
         statute or regulation.

                  (e) The captions and headings of this Agreement are for
         convenience of reference only and shall not affect the interpretation
         of this Agreement.

                  (f) This Agreement and other Loan Documents may use several
         different limitations, tests or measurements to regulate the same or
         similar matters. All such limitations, tests and measurements are
         cumulative and shall each be performed in accordance with their terms.

                  (g) Unless otherwise expressly provided, any reference to any
         action of the Agent or the Lenders by way of consent, approval or
         waiver shall be deemed modified by the phrase "in its/their sole
         discretion."

                  (h) This Agreement and the other Loan Documents are the result
         of negotiations among and have been reviewed by counsel to the Agent,
         the Company and the other parties, and are the products of all parties.
         Accordingly, they shall not be construed against the Lenders or the
         Agent merely because of the Agent's or Lenders' involvement in their
         preparation.

         1.03 ACCOUNTING PRINCIPLES. (a) Unless the context otherwise clearly
requires, all accounting terms not expressly defined herein shall be construed,
and all financial computations required under this Agreement shall be made, in
accordance with GAAP, consistently applied.

                  (b) References herein to "fiscal year" and "fiscal quarter"
         refer to such fiscal periods of the Company.

                  (c) In the event that any changes in GAAP occur after the date
         of this Agreement and such changes result in a material variation in
         the method of calculation of financial covenants or other terms of this
         Agreement, then the Company, the Agent and the Lenders agree to amend
         such provisions of this Agreement so as to equitably reflect such
         changes so that the criteria for evaluating the Company's financial
         condition will be the same after such changes as if such changes had
         not occurred.

                                   ARTICLE II

                                   THE CREDITS

         2.01 AMOUNTS AND TERMS OF COMMITMENTS. (a) TERM LOAN. Each Lender
severally agrees, on the terms and conditions set forth herein, to make a single
loan to the Company (each such loan, a "TERM LOAN") on the Closing Date in an
amount not to exceed such Lender's Term Loan Commitment as set forth on SCHEDULE
2.01. Amounts borrowed as a Term Loan which are repaid or prepaid by the Company
may not be reborrowed.

                  (b) THE REVOLVING CREDIT. Each Revolving Lender severally
         agrees, on the terms and conditions set forth herein, to make loans to
         the Company (each such loan, a "REVOLVING LOAN") from time to time on
         any Business Day during the period from the Closing Date to the
         Revolving Loan Termination Date, in an aggregate amount not to exceed
         at any time outstanding the amount set forth on SCHEDULE 2.01 (such
         amount, as the same may be reduced under SECTION 2.07 or as a result of
         one or more assignments under SECTION 11.08, the Revolving Lender's
         "REVOLVING LOAN COMMITMENT"); PROVIDED, HOWEVER, that, after giving
         effect to any Borrowing of Revolving Loans, the Effective Amount of all
         outstanding Revolving Loans, together with Swing Line Loans outstanding
         at such time and the Effective Amount of all L/C Obligations, shall not
         at any time exceed the lesser of (i) the Aggregate Revolving Loan
         Commitment or (ii) the Borrowing Base; AND PROVIDED FURTHER, that the
         Effective Amount of the Revolving Loans of any Revolving Lender plus
         the participation of such Revolving Lender in the Effective Amount of
         all L/C Obligations plus such Revolving Lender's Pro Rata Revolving
         Share of any outstanding Swing Line Loans shall not at any time exceed
         such Revolving Lender's Revolving Loan Commitment. Within the limits of
         each Revolving Lender's Commitment, and subject to the other terms and
         conditions hereof,

                                      34
<PAGE>

         the Company may borrow under this SUBSECTION 2.01(b), prepay under
         SECTION 2.08 and reborrow under this SUBSECTION 2.01(b).

         2.02 LOAN ACCOUNTS. (a) The Loans made by each Lender and the Letters
of Credit Issued by the Issuer shall be evidenced by one or more accounts or
records maintained by such Lender or Issuer, as the case may be, in the ordinary
course of business. The accounts or records maintained by the Agent, the Issuer
and each Lender shall be conclusive absent manifest error of the amount of the
Loans made by the Lenders to the Company and the Letters of Credit Issued for
the account of the Company, and the interest and payments thereon. Any failure
so to record or any error in doing so shall not, however, limit or otherwise
affect the obligation of the Company hereunder to pay any amount owing with
respect to the Loans or any Letter of Credit.

                  (b) The Company shall issue to each Lender notes in the form
         of EXHIBIT E-1 in the case of Revolving Loans and/or EXHIBIT E-2 in the
         case of Term Loans (each, a "NOTE" and collectively, the "NOTES") to
         evidence such Lender's Loans (or, in the case of Swing Line Loans, in
         the form of EXHIBIT F). Each Lender may, instead of or in addition to
         maintaining a loan account, endorse on the schedule annexed to its
         Note(s) the date, amount and maturity of each Loan made by it and the
         amount of each payment of principal made by the Company with respect
         thereto. Each such Lender is irrevocably authorized by the Company to
         endorse its Note(s) or Swing Line Note, as applicable, and each
         Lender's record shall be conclusive absent manifest error; PROVIDED,
         HOWEVER, that the failure of a Lender to make, or an error in making, a
         notation thereon with respect to any Loan shall not limit or otherwise
         affect the obligations of the Company hereunder or under any such Note
         or Swing Line Note to such Lender.

         2.03 PROCEDURE FOR BORROWING. (a) Each Borrowing shall be made upon the
Company's irrevocable notice delivered to the Agent in the form of a Notice of
Borrowing (which notice must be received by the Agent prior to 11:00 a.m.
(Central time) (i) three Business Days prior to the requested Borrowing Date, in
the case of Offshore Rate Loans; and (ii) one Business Day prior to the
requested Borrowing Date (or in the case of the initial Credit Extension, at the
option of the Agent, on the requested Borrowing Date), in the case of Base Rate
Loans, specifying:

                                    (A) the amount of the Borrowing, which shall
                           be for Offshore Rate Loans in an aggregate minimum of
                           $1,000,000 or any multiple of $100,000 in excess
                           thereof and for Base Rate Loans in an aggregate
                           minimum of $500,000 or any multiple of $100,000 in
                           excess thereof;

                                    (B) the requested Borrowing Date, which
                           shall be a Business Day;

                                      35
<PAGE>

                                    (C) the Type of Loans comprising the
                           Borrowing; and

                                    (D) with respect to Offshore Rate Loans, the
                           duration of the Interest Period for 1, 2, 3 or 6
                           months that is to be applicable to such Loans
                           included in such notice. If the Notice of Borrowing
                           fails to specify the duration of the Interest Period
                           for any Borrowing comprised of Offshore Rate Loans,
                           such Interest Period shall be three months;

         PROVIDED, HOWEVER, that with respect to the Borrowing to be made on the
         Closing Date, such Borrowing will consist of Base Rate Loans only.

                  (b) The Agent will promptly notify each applicable Lender of
         its receipt of any Notice of Borrowing and, in respect of Borrowings of
         Revolving Loans, of the amount of such Revolving Lender's Pro Rata
         Revolving Share of that Borrowing.

                  (c) Each Lender will make the amount of its Pro Rata Share of
         each Borrowing available to the Agent for the account of the Company at
         the Agent's Payment Office by 1:00 p.m. (Central time) on the Borrowing
         Date requested by the Company in funds immediately available to the
         Agent. The proceeds of all such Loans will then be made available to
         the Company by the Agent at such office by crediting the account of the
         Company on the books of BofA with the aggregate of the amounts made
         available to the Agent by the Lenders and in like funds as received by
         the Agent.

                  (d) After giving effect to any Borrowing, unless the Agent
         shall otherwise consent, there may not be more than six different
         Interest Periods in effect.

                  (e) The Company hereby authorizes the Lenders and the Agent to
         accept Notices of Borrowing based on telephonic notices made by any
         person or persons the Agent or any Lender in good faith believes to be
         acting on behalf of the Company. The Company agrees to deliver promptly
         to the Agent a written confirmation of each telephonic notice, signed
         by a Responsible Officer or an authorized designee. If the written
         confirmation differs in any material respect from the telephonic
         notice, the records of the Agent and the Lenders shall govern absent
         manifest error.

         2.04     CONVERSION AND CONTINUATION ELECTIONS.  (a) The Company may,
upon irrevocable notice to the Agent in accordance with SUBSECTION 2.04(b):

                           (i)  elect, as of any Business Day, in the case of
                  Base Rate Loans, or as of the last day of the applicable
                  Interest Period, in the case of any other Type of Revolving
                  Loans or Term Loans, to convert any such Loans (or any part
                  thereof in an amount not less than $1,000,000 or that is in an
                  integral multiple of $100,000 in excess thereof for Offshore
                  Rate Loans and not less than

                                      36
<PAGE>

                  $500,000 or that is in an integral multiple of $100,000 in
                  excess thereof for Base Rate Loans) into Loans of any other
                  Type; or

                           (ii) elect as of the last day of the applicable
                  Interest Period, to continue any Revolving Loans or Term Loans
                  having Interest Periods expiring on such day (or any part
                  thereof in an amount not less than $1,000,000 or that is in an
                  integral multiple of $100,000 in excess thereof for Offshore
                  Rate Loans);

         PROVIDED, that if at any time the aggregate amount of Offshore Rate
         Loans in respect of any Borrowing is reduced, by payment, prepayment,
         or conversion of part thereof to be less than $1,000,000 such Offshore
         Rate Loans shall automatically convert into Base Rate Loans, and on and
         after such date the right of the Company to continue such Loans as, and
         convert such Loans into, Offshore Rate Loans shall terminate.

                  (b) The Company shall deliver a Notice of
         Conversion/Continuation to be received by the Agent not later than
         11:00 a.m. (Central time) at least (i) three Business Days in advance
         of the Conversion/Continuation Date, if the Loans are to be converted
         into or continued as Offshore Rate Loans; and (ii) at least one
         Business Day in advance of the Conversion/Continuation Date, if the
         Loans are to be converted into Base Rate Loans, specifying:

                           (i)     the proposed Conversion/Continuation Date;

                           (ii)    the aggregate amount of Loans to be
                           converted or continued;

                           (iii)   the Type of Loans resulting from the proposed
                           conversion or continuation; and

                           (iv)    other than in the case of conversions into
                           Base Rate Loans, the duration of the requested
                           Interest Period.

                  (c) If upon the expiration of any Interest Period applicable
         to Offshore Rate Loans, the Company has failed to select timely a new
         Interest Period to be applicable to such Offshore Rate Loans, as the
         case may be, or if any Default or Event of Default then exists, the
         Company shall be deemed to have elected to convert such Offshore Rate
         Loans into Base Rate Loans effective as of the expiration date of such
         Interest Period.

                  (d) The Agent will promptly notify each applicable Lender of
         its receipt of a Notice of Conversion/Continuation, or, if no timely
         notice is provided by the Company, the Agent will promptly notify each
         applicable Lender of the details of any automatic conversion. All
         conversions and continuations shall be made ratably

                                      37
<PAGE>

         according to the respective outstanding principal amounts of the Loans
         with respect to which the notice was given held by each Lender.

                  (e) Unless the Required Lenders otherwise consent, during the
         existence of a Default or Event of Default, the Company may not elect
         to have a Loan converted into or continued as an Offshore Rate Loan.

                  (f) After giving effect to any conversion or continuation of
         Loans, unless the Agent shall otherwise consent, there may not be more
         than six (6) different Interest
         Periods in effect.

                  (g) The Company hereby authorizes the Lenders and the Agent to
         accept Notices of Conversion/Continuation based on telephonic notices
         made by any person or persons the Agent or any Lender in good faith
         believes to be acting on behalf of the Company. The Company agrees to
         deliver promptly to the Agent a written confirmation of each telephonic
         notice, signed by a Responsible Officer. If the written confirmation
         differs in any material respect from the telephonic notice, the records
         of the Agent and the Lenders shall govern absent manifest error.

         2.05 THE SWING LINE LOANS. Subject to the terms and conditions hereof,
the Swing Line Lender agrees to make Swing Line Loans to the Company from time
to time prior to the Revolving Loan Termination Date in an aggregate principal
amount at any one time outstanding not to exceed $4,000,000; PROVIDED, that
after giving effect to any such Swing Line Loan, the Effective Amount of all
Revolving Loans, Swing Line Loans and L/C Obligations at such time would not
exceed the lesser of (i) the Aggregate Revolving Loan Commitment or (ii) the
Borrowing Base at such time. Prior to the Revolving Loan Termination Date, the
Company may use the Swing Line Commitment by borrowing, prepaying the Swing Line
Loans in whole or in part, and reborrowing, all in accordance with the terms and
conditions hereof. All Swing Line Loans shall bear interest at the Swing Line
Rate and shall not be entitled to be converted into Loans that bear interest at
any other rate.

         2.06 PROCEDURE FOR SWING LINE LOANS. (a) The Company may borrow under
the Swing Line Commitment on any Business Day until the Revolving Loan
Termination Date; PROVIDED, that the Company shall give the Swing Line Lender
irrevocable written notice signed by a Responsible Officer or an authorized
designee (which notice must be received by the Swing Line Lender prior to 11:00
a.m. (Central time)) with a copy to the Agent specifying the amount of the
requested Swing Line Loan, which shall be in a minimum amount of $100,000 or a
whole multiple of $50,000 in excess thereof. The proceeds of the Swing Line Loan
will be made available by the Swing Line Lender to the Company in immediately
available funds at the office of the Swing Line Lender by 1:00 p.m. (Central
time) on the date of such notice. The Company may at any time and from time to
time, prepay the Swing Line Loans, in whole or in part, without premium or
penalty, by notifying the Swing Line Lender prior to 11:00 a.m. (Central time)
on any Business Day of the date and amount of prepayment with a copy to

                                      38
<PAGE>

the Agent. If any such notice is given, the amount specified in such notice
shall be due and payable on the date specified therein. Partial prepayments
shall be in an aggregate principal amount of $100,000 or a whole multiple of
$50,000 in excess thereof.

                  (b) The Swing Line Lender may in its sole discretion (or
         will at the direction of the Company) on any Business Day, on behalf
         of the Company (which hereby irrevocably directs the Swing Line
         Lender to act on its behalf) request the Agent to notify each
         Revolving Lender to make a Base Rate Loan in an amount equal to such
         Revolving Lender's Pro Rata Revolving Share of the aggregate
         principal amount of the Swing Line Loans outstanding on the date
         such notice is given. Unless any of the events described in
         SUBSECTION 9.01(f) OR (g) shall have occurred with respect to the
         Company (in which event the procedures of paragraph (d) of this
         SECTION 2.06 shall apply) each Revolving Lender shall make the
         proceeds of its Revolving Loan available to the Agent for the
         account of the Swing Line Lender at the Agent's Payment Office in
         funds immediately available prior to 1:00 p.m. (Central time) on the
         Business Day next succeeding the date such notice is given. The
         proceeds of such Revolving Loans shall be immediately applied to
         repay the outstanding Swing Line Loans. Effective on the day such
         Revolving Loans are made, the portion of the Swing Line Loans so
         paid shall no longer be outstanding as Swing Line Loans and shall no
         longer be due under the Swing Line Note. The Company shall pay to
         the Swing Line Lender, promptly following the Swing Line Lender's
         demand, the amount of its outstanding Swing Line Loans to the extent
         amounts received from the Revolving Lenders are not sufficient to
         repay in full such outstanding Swing Line Loans.

                  (c) Notwithstanding anything herein to the contrary, the Swing
         Line Lender (i) shall not be obligated to make any Swing Line Loan if
         the conditions set forth in ARTICLE V have not been satisfied and (ii)
         shall not make any requested Swing Line Loan if, prior to 11:00 a.m.
         (Central time) on the date of such requested Swing Line Loan, it has
         received a written notice from the Agent or any Revolving Lender
         directing it not to make further Swing Line Loans because one or more
         of the conditions specified in ARTICLE V are not then satisfied.

                  (d) If prior to the making of a Revolving Loan required to be
         made by SUBSECTION 2.06(b) an Event of Default described in SUBSECTION
         9.01(f) OR 9.01(g) shall have occurred and be continuing with respect
         to the Company, each Revolving Lender will, on the date such Revolving
         Loan was to have been made pursuant to the notice described in
         SUBSECTION 2.06(b), purchase an undivided participating interest in the
         outstanding Swing Line Loans in an amount equal to its Pro Rata
         Revolving Share of the aggregate principal amount of Swing Line Loans
         then outstanding. Each Revolving Lender will immediately transfer to
         the Agent for the benefit of the Swing Line Lender, in immediately
         available funds, the amount of its participation.

                                      39
<PAGE>

                  (e) Whenever, at any time after a Revolving Lender has
         purchased a participating interest in a Swing Line Loan, the Swing Line
         Lender receives any payment on account thereof, the Swing Line Lender
         will distribute to the Agent for delivery to each Revolving Lender its
         participating interest in such amount (appropriately adjusted, in the
         case of interest payments, to reflect the period of time during which
         such Revolving Lender's participating interest was outstanding and
         funded); PROVIDED, HOWEVER, that in the event that such payment
         received by the Swing Line Lender is required to be returned, such
         Revolving Lender will return to the Agent for delivery to the Swing
         Line Lender any portion thereof previously distributed by the Swing
         Line Lender to it.

                  (f) Each Lender's obligation to make the Revolving Loans
         referred to in SUBSECTION 2.06(b) and to purchase participating
         interests pursuant to SUBSECTION 2.06(d) shall be absolute and
         unconditional and shall not be affected by any circumstance, including,
         without limitation, (i) any set-off, counterclaim, recoupment, defense
         or other right which such Revolving Lender or the Company may have
         against the Swing Line Lender, the Company or any other Person for any
         reason whatsoever, (ii) the occurrence or continuance of a Default or
         an Event of Default, (iii) any adverse change in the condition
         (financial or otherwise) of the Company, (iv) any breach of this
         Agreement or any other Loan Document by the Company, any Subsidiary or
         any other Lender, or (v) any other circumstance, happening or event
         whatsoever, whether or not similar to any of the foregoing.

                  (g) The Company shall repay any Swing Line Loan in full no
         later than seven (7) days after such loan is made either by converting
         the Loan to a Revolving Loan or repaying the Swing Line Loan by other
         means not prohibited by this Agreement.

         2.07 VOLUNTARY TERMINATION OR REDUCTION OF REVOLVING LOAN COMMITMENTS.
(a) The Company may, upon not less than five Business Days' prior notice to the
Agent, terminate the Revolving Loan Commitments, or permanently reduce the
Revolving Loan Commitments by an amount of $1,000,000 or any multiple of
$1,000,000 in excess thereof; UNLESS, after giving effect thereto and to any
prepayments of Loans made on the effective date thereof,

                           (i)  the Effective Amount of all Revolving Loans,
                  Swing Line Loans and L/C Obligations together would exceed the
                  amount of the Aggregate Revolving Loan Commitment then in
                  effect, or

                           (ii) the Effective Amount of all L/C Obligations
                  then outstanding would exceed the L/C Commitment. Once
                  reduced in accordance with this Section, the Revolving Loan
                  Commitments may not be increased. Any reduction of the
                  Revolving Loan Commitments shall be applied to each
                  Revolving Lender according to its Pro Rata Revolving Share.
                  If and to the extent specified by the

                                      40
<PAGE>

                  Company in the notice to the Agent, some or all of the
                  reduction in the Revolving Loan Commitments shall be
                  applied to reduce the L/C Commitment. All accrued
                  commitment and letter of credit fees to, but not including,
                  the effective date of any reduction or termination of
                  Revolving Loan Commitments, shall be paid on the effective
                  date of such reduction or termination.

                  (b) At no time shall the Swing Line Commitment exceed the
         Aggregate Revolving Loan Commitment, and any reduction of the
         Aggregate Revolving Loan Commitment which reduces the Aggregate
         Revolving Loan Commitment below the then-current amount of the Swing
         Line Commitment shall result in an automatic corresponding reduction
         of the Swing Line Commitment to the amount of the Aggregate
         Revolving Loan Commitment, as so reduced, without any action on the
         part of the Swing Line Lender. At no time shall the Swing Line
         Commitment exceed the Revolving Loan Commitment of the Swing Line
         Lender, and any reduction of the Aggregate Revolving Loan Commitment
         which reduces the Revolving Loan Commitment of the Swing Line Lender
         below the then-current amount of the Swing Line Commitment shall
         result in an automatic corresponding reduction of the Swing Line
         Commitment to the amount of the Revolving Loan Commitment of the
         Swing Line Lender, as so reduced, without any action on the part of
         the Swing Line Lender.

         2.08 OPTIONAL PREPAYMENTS. Subject to SECTION 4.04, the Company may, at
any time or from time to time, upon not less than two (2) Business Days'
irrevocable notice to the Agent, in respect of Offshore Rate Loans, and in
respect of Base Rate Loans, by not later than 11:00 a.m. (Central time) on the
prepayment date, prepay Loans in whole or in part, in minimum amounts of
$1,000,000 or any multiple of $100,000 in excess thereof for Offshore Rate Loans
and in minimum amounts of $500,000 or any multiple of $100,000 in excess thereof
for Base Rate Loans. Such notice of prepayment shall specify the date and amount
of such prepayment, which Loans are to be prepaid and the Type(s) of such Loans
to be prepaid. The Agent will promptly notify each Lender of its receipt of any
such notice, and of such Lender's Pro Rata Share of such prepayment. If such
notice is given by the Company, the Company shall make such prepayment and the
payment amount specified in such notice shall be due and payable on the date
specified therein, together, in the case of Offshore Rate Loans, with accrued
interest to each such date on the amount prepaid and any amounts required
pursuant to SECTION 4.04. Optional prepayments shall be applied to Term Loans in
the inverse order of maturity. Optional Prepayments shall be applied to each
Lender according to its Pro Rata Share.

         2.09 MANDATORY PREPAYMENTS OF LOANS. (a) If on any date the Effective
Amount of L/C Obligations exceeds the L/C Commitment, the Company shall Cash
Collateralize on such date the outstanding Letters of Credit in an amount equal
to the excess of the maximum amount then available to be drawn under the Letters
of Credit over the Aggregate L/C Commitment. Subject to SECTION 4.04, if on any
date after giving effect to any Cash Collateralization made on such date
pursuant to the preceding sentence, the Effective Amount

                                      41
<PAGE>

of all Revolving Loans, Swing Line Loans and Term Loans then outstanding plus
the Effective Amount of all L/C Obligations exceeds the Aggregate Commitment,
the Company shall immediately, and without notice or demand, prepay the
outstanding principal amount of the Revolving Loans and L/C Advances by an
amount equal to the applicable excess.

                  (b) Within five (5) Business Days after the end of each
         fiscal quarter, the Company shall prepay the Loans in an amount
         equal to 100% of the sum of (a) the Net Proceeds realized upon all
         Asset Dispositions made by the Company or any Subsidiary in such
         fiscal quarter, the insurance proceeds received by the Company or
         any Subsidiary in such fiscal quarter following a casualty involving
         such Person's property, and the payments received by the Company or
         any Subsidiary in such fiscal quarter from a condemnation of such
         Person's property, aggregating in excess of $500,000, to the extent
         any of the foregoing Net Proceeds are not applied (or committed to
         be applied) within 180 days after the consummation or receipt
         thereof, as applicable, to the purchase of similar assets that are
         not classified as current assets under GAAP and are used or useful
         in the business of the Company and its Subsidiaries or to the repair
         or restoration of such Person's property. The amount of such
         prepayment shall be applied first to the then outstanding principal
         balance of the Term Loans in inverse order of maturity and then to
         the then outstanding Revolving Loans. The Revolving Loan Commitment
         of each Lender shall automatically be reduced by an amount equal to
         such Lender's Pro Rata Revolving Share of the amount of the
         prepayment pursuant to this SUBSECTION 2.09(b), if any, applied to
         the Revolving Loans. All accrued commitment fees to, but not
         including the effective date of any reduction or termination of the
         Revolving Loan Commitments, shall be paid on the effective date of
         such reduction or termination.

                  (c) On each January 31st, beginning January 31, 2001, the
         Company shall prepay the Loans in an amount equal to 50% of the Excess
         Cash Flow, if any, generated by the Company and its Subsidiaries during
         the immediately preceding fiscal year of the Company. All prepayments
         shall be applied first to the Term Loans and then to Revolving Loans as
         specified in SECTION 2.09(g) hereof.

                  (d) If the Company or any Subsidiary shall incur any
         Indebtedness (other than Indebtedness permitted to be incurred by
         SUBSECTION 8.05), the Company shall promptly notify the Agent of the
         estimated Net Proceeds of such issuance to be received by the Company
         or such Subsidiary in respect thereof. Promptly upon, and in no event
         later than three (3) days after, receipt by the Company or such
         Subsidiary of Net Proceeds of such incurrence, the Company shall prepay
         the Obligations in an amount equal to 100% of such Net Proceeds.

                  (e) If the Company or any Subsidiary shall issue new common
         or preferred equity, the Company shall promptly notify the Agent of
         the estimated Net Proceeds of such issuance to be received by the
         Company or such Subsidiary in respect thereof.

                                      42
<PAGE>

         Promptly upon, and in no event later than three (3) days after,
         receipt by the Company or such Subsidiary of Net Proceeds of such
         issuance, the Company shall prepay the Obligations in an amount
         equal to 50% of such Net Proceeds.

                  (f) If at any time on or after December 31, 2001, the
         Obligations exceed the Borrowing Base, PLUS 80% of the appraised value
         of the Company's and its Subsidiaries' real estate and 50% of the book
         value of the Company's and its Subsidiaries' property, plant and
         equipment other than real estate, the Company shall immediately and
         without notice or demand, prepay the outstanding Term Loans and then
         the Revolving Loans by an amount equal to the applicable excess.

                  (g) Any prepayments pursuant to SUBSECTIONS 2.09(d)-(f) shall
         be applied first to the outstanding principal balance of the Term Loans
         in inverse order of maturity, and then to the outstanding principal
         balance of the Revolving Loans (without any reduction in the Revolving
         Loan Commitment of any Lender). The Borrower shall pay, together with
         each prepayment under this SECTION 2.09, accrued interest on the amount
         prepaid and any amounts required pursuant to SECTION 4.03 to reimburse
         Agent for any breakage or redeployment costs incurred by Lenders
         relating prepayments of Offshore Rate Loans.

         2.10     REPAYMENT.  (a) Term Loans.  The Company shall repay the Term
Loans on each date set forth below as follows (each a "PRINCIPAL PAYMENT DATE"):

</TABLE>

                  (b) THE REVOLVING CREDIT.  The Company shall repay to the
         Lenders on the Revolving Loan Termination Date the aggregate principal
         amount of Revolving Loans outstanding on such date.

         2.11 INTEREST. (a) Each Revolving Loan and Term Loan shall bear
interest on the outstanding principal amount thereof from the applicable
Borrowing Date at a rate per annum equal to the Offshore Rate or the Base Rate,
as the case may be (and subject to the Company's right to convert to other Types
of Loans under SECTION 2.04), PLUS the Applicable Offshore Rate Margin or the
Applicable Base Rate Margin, as applicable.

                  (b) Interest on each Revolving Loan and Term Loan shall be
         paid in arrears on each Interest Payment Date. Interest on Base Rate
         Loans shall also be paid on the date of any payment (including
         prepayment) in full thereof. Interest on Offshore Rate Loans shall also
         be paid on the date of any prepayment of Loans under SECTION 2.08 or
         2.09 for the portion of the Loans so prepaid and upon payment
         (including prepayment) in full thereof. During the existence of any
         Event of Default, interest on all Loans shall be paid on demand of the
         Agent at the request or with the consent of the Required Lenders.

                  (c) Notwithstanding subsection (a) of this Section, if any
         amount of principal of or interest on any Loan, or any other amount
         payable hereunder or under any other Loan Document is not paid in full
         when due (whether at stated maturity, by acceleration, demand or
         otherwise), the Company agrees to pay interest on such unpaid principal
         or other amount, from the date such amount becomes due until the date
         such amount is paid in full, and after as well as before any entry of
         judgment thereon to the extent permitted by law, payable on demand, at
         a fluctuating rate per annum equal to the Base Rate, plus the
         Applicable Base Rate Margin, plus two percent (2.0%).

                  (d) Anything herein to the contrary notwithstanding, the
         obligations of the Company to any Lender hereunder shall be subject to
         the limitation that payments of interest shall not be required for any
         period for which interest is computed hereunder, to the extent (but
         only to the extent) that contracting for or receiving such payment by
         such Lender would be contrary to the provisions of any law applicable
         to such Lender

                                      44
<PAGE>

         limiting the highest rate of interest that may be lawfully
         contracted for, charged or received by such Lender, and in such
         event the Company shall pay such Lender interest at the highest rate
         permitted by applicable law.

         2.12 FEES. In addition to certain fees described in SECTION 3.08:

                  (a) ARRANGEMENT FEES.  The Company shall pay such fees to
         the Agent as are required by the letter agreement ("FEE LETTER")
         between the Company and Agent dated December 10, 1999.

                  (b) COMMITMENT FEES. The Company shall pay to the Agent for
         the account of each Revolving Lender a commitment fee on the average
         daily unused portion of such Revolving Lender's Revolving Loan
         Commitment, computed on a quarterly basis in arrears on the last
         Business Day of each calendar quarter based upon the daily utilization
         for that quarter as calculated by the Agent, equal to the Applicable
         Commitment Fee Percentage. For purposes of calculating utilization
         under this subsection, the Revolving Loan Commitments shall be deemed
         used to the extent of the Effective Amount of Revolving Loans then
         outstanding (excluding any outstanding Swing Line Loans), plus the
         Effective Amount of L/C Obligations then outstanding. Such commitment
         fee shall accrue from the date hereof to the Revolving Loan Termination
         Date and shall be due and payable quarterly in arrears on the last
         Business Day of each calendar quarter commencing on March 31, 2000
         through the Revolving Loan Termination Date, with the final payment to
         be made on the Revolving Loan Termination Date; PROVIDED that, in
         connection with any reduction or termination of Revolving Loan
         Commitments under SECTION 2.07, the accrued commitment fee calculated
         for the period ending on such date shall also be paid on the date of
         such reduction or termination, with the following quarterly payment
         being calculated on the basis of the period from such reduction or
         termination date to such quarterly payment date. The commitment fees
         provided in this subsection shall accrue at all times after the
         above-mentioned commencement date, including at any time during which
         one or more conditions in ARTICLE V are not met.

         2.13 COMPUTATION OF FEES AND INTEREST. (a) All computations of interest
for Base Rate Loans when the Base Rate is determined by BofA's "prime rate"
shall be made on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed. All other computations of fees and interest shall be made
on the basis of a 360-day year and actual days elapsed (which results in more
interest being paid than if computed on the basis of a 365-day year). Interest
and fees shall accrue during each period during which interest or such fees are
computed from the first day thereof to the last day thereof.

                  (b) Each determination of an interest rate by the Agent shall
         be conclusive and binding on the Company and the Lenders in the absence
         of manifest error.

<PAGE>

                  (c) FACILITY FEE. Each Lender whose Aggregate Commitment is
         equal to or greater than $15,000,000 shall receive a Facility Fee
         payable at Closing by the Agent in an amount equal to .45% of such
         Aggregate Commitment. Each Lender whose Aggregate Commitment is equal
         to or less than $10,000,000 shall receive a Facility Fee payable at the
         Closing by the Agent in an amount equal to .35% of such Aggregate
         Commitment.

         2.14 PAYMENTS BY THE COMPANY. (a) All payments to be made by the
Company shall be made without set-off, recoupment or counterclaim. Except as
otherwise expressly provided herein, all payments by the Company shall be
made to the Agent for the account of the Lenders at the Agent's Payment
Office, and shall be made in dollars and in immediately available funds, no
later than 11:00 a.m. (Central time) on the date specified herein. The Agent
will promptly distribute to each Lender its applicable share of such payment
in like funds as received which, except as otherwise expressly provided
herein, shall be based upon such Lender's Pro Rata Share of the Loans in
respect of which such payment has been made. Any payment received by the
Agent later than 1:00 p.m. (Central time) shall be deemed to have been
received on the following Business Day and any applicable interest or fee
shall continue to accrue.

                  (b) Subject to the provisions set forth in the definition of
         "Interest Period" herein, whenever any payment is due on a day other
         than a Business Day, such payment shall be made on the following
         Business Day, and such extension of time shall in such case be included
         in the computation of interest or fees, as the case may be.

                  (c) Unless the Agent receives notice from the Company prior
         to the date on which any payment is due to the Lenders that the
         Company will not make such payment in full as and when required, the
         Agent may assume that the Company has made such payment in full to
         the Agent on such date in immediately available funds and the Agent
         may (but shall not be so required), in reliance upon such
         assumption, distribute to each Lender on such due date an amount
         equal to the amount then due such Lender.  If and to the extent the
         Company has not made such payment in full to the Agent, each Lender
         shall repay to the Agent on demand such amount distributed to such
         Lender, together with interest thereon at the Federal Funds Rate for
         each day from the date such amount is distributed to such Lender
         until the date repaid.

         2.15 PAYMENTS BY THE LENDERS TO THE AGENT. (a) Unless the Agent
receives notice from a Lender on or prior to the Closing Date or, with respect
to any Borrowing after the Closing Date, at least one Business Day prior to the
date of such Borrowing, that such Lender will not make available as and when
required hereunder to the Agent for the account of the Company the amount of
that Lender's Pro Rata Share of the Borrowing, the Agent may assume that each
Lender has made such amount available to the Agent in immediately available
funds on the Borrowing Date and the Agent may (but shall not be so required), in
reliance upon such assumption, make available to the Company on such date a
corresponding

                                      46
<PAGE>

amount. If and to the extent any Lender shall not have made its full amount
available to the Agent in immediately available funds and the Agent in such
circumstances has made available to the Company such amount, that Lender
shall on the Business Day following such Borrowing Date make such amount
available to the Agent, together with interest at the Federal Funds Rate for
each day during such period. A notice of the Agent submitted to any Lender
with respect to amounts owing under this subsection (a) shall be conclusive,
absent manifest error. If such amount is so made available, such payment to
the Agent shall constitute such Lender's Loan on the date of Borrowing for
all purposes of this Agreement. If such amount is not made available to the
Agent on the Business Day following the Borrowing Date, the Agent will notify
the Company of such failure to fund and, upon demand by the Agent, the
Company shall pay such amount to the Agent for the Agent's account, together
with interest thereon for each day elapsed since the date of such Borrowing,
at a rate per annum equal to the interest rate applicable at the time to the
Loans comprising such Borrowing. The Company may, subject to the provisions
of SECTION 2.05 AND 2.06, utilize the proceeds of a Swing Line Loan to make
such payment to the Agent.

                  (b) The failure of any Lender to make any Loan on any
         Borrowing Date shall not relieve any other Lender of any obligation
         hereunder to make a Loan on such Borrowing Date, but no Lender shall be
         responsible for the failure of any other Lender to make the Loan to be
         made by such other Lender on any Borrowing Date.

         2.16 SHARING OF PAYMENTS, ETC. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Lender shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Lenders such participations in the
Loans made by them as shall be necessary to cause such purchasing Lender to
share the excess payment pro rata with each of them; PROVIDED, HOWEVER, that if
all or any portion of such excess payment is thereafter recovered from the
purchasing Lender, such purchase shall to that extent be rescinded and each
other Lender shall repay to the purchasing Lender the purchase price paid
therefor, together with an amount equal to such paying Lender's ratable share
(according to the proportion of (i) the amount of such paying Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Company agrees that any Lender so
purchasing a participation from another Lender may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to SECTION 11.10) with respect to such participation as
fully as if such Lender were the direct creditor of the Company in the amount of
such participation. The Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments.

         2.17 SECURITY GUARANTIES. (a)  All obligations of the Company and
the Guarantors under this Agreement, the Notes and all other Loan Documents
shall be secured in accordance with the Collateral Documents.

                  (b) All obligations of the Company under this Agreement, each
         of the Notes and all other Loan Documents shall be unconditionally
         guaranteed by the Guarantors pursuant to the Subsidiary Guaranty and
         the ST Holdings Guaranty.

                                   ARTICLE III

                              THE LETTERS OF CREDIT

         3.01 THE LETTER OF CREDIT SUBFACILITY. (a) On the terms and conditions
set forth herein (i) the Issuer agrees, (A) from time to time on any Business
Day, during the period from the Closing Date to the day which is five days prior
to the Revolving Loan Termination Date, to issue Letters of Credit for the
account of the Company in an aggregate Stated Amount at any one time that,
together with the aggregate Stated Amount of all other outstanding Letters of
Credit issued pursuant hereto, does not exceed the L/C Commitment, and to amend
or renew Letters of Credit previously issued by it, in accordance with
SUBSECTIONS 3.02(c) and 3.02(d), and (b) to honor drafts under the Letters of
Credit; and (ii) the Lenders severally agree to participate in Letters of Credit
Issued for the account of the Company; provided, that the Issuer shall not be
obligated to Issue, and no Revolving Lender shall be obligated to participate
in, any Letter of Credit if as of the date of Issuance of such Letter of Credit
(the "ISSUANCE DATE") (1) the Effective Amount of all L/C Obligations plus the
Effective Amount of all Revolving Loans and of all Swing Line Loans exceeds the
lesser of (i) Aggregate Revolving Loan Commitment and (ii) the Borrowing Base at
such time, (2) the participation of any Lender in the Effective Amount of all
L/C Obligations plus the Effective Amount of the Revolving Loans of such Lender
and such Revolving Lender's Pro Rata Revolving Share of any outstanding Swing
Line Loans exceeds such Lender's Commitment, or (3) the Effective Amount of L/C
Obligations exceeds the L/C Commitment. Within the foregoing limits, and subject
to the other terms and conditions hereof, the Company's ability to obtain
Letters of Credit shall be fully revolving, and, accordingly, the Company may,
during the foregoing period, obtain Letters of Credit to replace Letters of
Credit which have expired or which have been drawn upon and reimbursed.

                  (b) The Issuer is under no obligation to, and shall not, Issue
         any Letter of Credit if:

                           (i) any order, judgment or decree of any Governmental
                  Authority or arbitrator shall by its terms purport to enjoin
                  or restrain the Issuer from Issuing such Letter of Credit, or
                  any Requirement of Law applicable to the Issuer or any request
                  or directive (whether or not having the force of law) from any

                                       48
<PAGE>

                  Governmental Authority with jurisdiction over the Issuer
                  shall prohibit, or request that the Issuer refrain from,
                  the Issuance of letters of credit generally or such Letter
                  of Credit in particular or shall impose upon the Issuer
                  with respect to such Letter of Credit any restriction,
                  reserve or capital requirement (for which the Issuer is not
                  otherwise compensated hereunder) not in effect on the
                  Closing Date, or shall impose upon the Issuer any
                  unreimbursed loss, cost or expense which was not applicable
                  on the Closing Date and which the Issuer in good faith
                  deems material to it; provided, however, that in such event
                  any of the other Lenders may, in their sole discretion,
                  with the consent of the Company, become an Issuing Lender
                  hereunder;

                           (ii)  the Issuer has received written notice from any
                  Revolving Lender, the Agent or the Company, on or prior to the
                  Business Day prior to the requested date of Issuance of such
                  Letter of Credit, that one or more of the applicable
                  conditions contained in ARTICLE V is not then satisfied;

                           (iii) the expiry date of any requested Letter of
                  Credit is (A) more than 365 days after the date of Issuance,
                  unless the Required Revolving Lenders have approved such
                  expiry date in writing, or (B) after the date which is five
                  days prior to the Revolving Loan Termination Date, unless all
                  of the Revolving Lenders have approved such expiry date in
                  writing;

                           (iv)  the expiry date of any requested Letter of
                  Credit is prior to the maturity date of any financial
                  obligation to be supported by the requested Letter of Credit;

                           (v)   any requested Letter of Credit does not provide
                  for drafts, or is not otherwise in form and substance
                  acceptable to the Issuer; or

                           (vi)  such Letter of Credit is to be denominated in a
                  currency other than Dollars.

         3.02 ISSUANCE, AMENDMENT AND RENEWAL OF LETTERS OF CREDIT. (a) Each
Letter of Credit shall be issued upon the irrevocable written request of the
Company received by the Issuer (with a copy sent by the Company to the Agent) at
least four days (or such shorter time as the Issuer may agree in a particular
instance in its sole discretion) prior to the proposed date of issuance. Each
such request for issuance of a Letter of Credit shall be by facsimile, confirmed
immediately in an original writing, in the form of an L/C Application (or such
other form as shall be acceptable to the Issuer), and shall specify in form and
detail satisfactory to the Issuer: (i) the proposed date of issuance of the
Letter of Credit (which shall be a Business Day); (ii) the face amount of the
Letter of Credit; (iii) the expiry date of the Letter of Credit; (iv) the name
and address of the beneficiary thereof; (v) the documents to be presented by the
beneficiary of the Letter of Credit in case of any drawing thereunder; (vi) the
full text of any

                                      49
<PAGE>

certificate to be presented by the beneficiary in case of any drawing
thereunder; and (vii) such other matters as the Issuer may require.

                  (b) At least two Business Days prior to the Issuance of any
         Letter of Credit (or such shorter time as the Agent may agree in a
         particular instance in its sole discretion), the Issuer will confirm
         with the Agent (by telephone or in writing) that the Agent has
         received a copy of the L/C Application or L/C Amendment Application
         from the Company and, if not, the Issuer will provide the Agent with
         a copy thereof. Unless the Issuer has received notice on or before
         the Business Day immediately preceding the date the Issuer is to
         issue a requested Letter of Credit from the Agent (A) directing the
         Issuer not to issue such Letter of Credit because such issuance is
         not then permitted under SUBSECTION 3.01(a) as a result of the
         limitations set forth in clauses (1) through (3) thereof or
         SUBSECTION 3.01(b)(ii); or (B) that one or more conditions specified
         in ARTICLE V are not then satisfied; then, subject to the terms and
         conditions hereof, the Issuer shall, on the requested date, issue a
         Letter of Credit for the account of the Company in accordance with
         the Issuer's usual and customary business practices.

                  (c) From time to time while a Letter of Credit is outstanding
         and prior to the Revolving Loan Termination Date, the Issuer will, upon
         the written request of the Company received by the Issuer (with a copy
         sent by the Company to the Agent) at least three days (or such shorter
         time as the Issuer may agree in a particular instance in its sole
         discretion) prior to the proposed date of amendment, amend any Letter
         of Credit issued by it. Each such request for amendment of a Letter of
         Credit shall be made by facsimile, confirmed immediately in an original
         writing, made in the form of an L/C Amendment Application and shall
         specify in form and detail satisfactory to the Issuer: (i) the Letter
         of Credit to be amended; (ii) the proposed date of amendment of the
         Letter of Credit (which shall be a Business Day); (iii) the nature of
         the proposed amendment; and (iv) such other matters as the Issuer may
         require. The Issuer shall be under no obligation to amend any Letter of
         Credit if: (A) the Issuer would have no obligation at such time to
         issue such Letter of Credit in its amended form under the terms of this
         Agreement; or (B) the beneficiary of any such letter of Credit does not
         accept the proposed amendment to the Letter of Credit. The Agent will
         promptly notify the Revolving Lenders of the receipt by it of any L/C
         Application or L/C Amendment Application.

                  (d) The Issuer and the Lenders agree that, while a Letter of
         Credit is outstanding and prior to the Revolving Loan Termination Date,
         at the option of the Company and upon the written request of the
         Company received by the Issuer (with a copy sent by the Company to the
         Agent) at least five days (or such shorter time as the Issuer may agree
         in a particular instance in its sole discretion) prior to the proposed
         date of notification of renewal, the Issuer shall be entitled to
         authorize the automatic renewal of any Letter of Credit issued by it.
         Each such request for renewal of a Letter of Credit shall be made by
         facsimile, confirmed immediately in an original writing, in

                                       50

<PAGE>

         the form of an L/C Amendment Application, and shall specify in form
         and detail satisfactory to the Issuer: (i) the Letter of Credit to
         be renewed; (ii) the proposed date of notification of renewal of the
         Letter of Credit (which shall be a Business Day); (iii) the revised
         expiry date of the Letter of Credit; and (iv) such other matters as
         the Issuer may require. The Issuer shall be under no obligation so
         to renew any Letter of Credit if: (A) the Issuer would have no
         obligation at such time to issue or amend such Letter of Credit in
         its renewed form under the terms of this Agreement; or (B) the
         beneficiary of any such Letter of Credit does not accept the
         proposed renewal of the Letter of Credit. If any outstanding Letter
         of Credit shall provide that it shall be automatically renewed
         unless the beneficiary thereof receives notice from the Issuer that
         such Letter of Credit shall not be renewed, and if at the time of
         renewal the Issuer would be entitled to authorize the automatic
         renewal of such Letter of Credit in accordance with this SUBSECTION
         3.02(d) upon the request of the Company but the Issuer shall not
         have received any L/C Amendment Application from the Company with
         respect to such renewal or other written direction by the Company
         with respect thereto, the Issuer shall nonetheless be permitted to
         allow such Letter of Credit to renew, and the Company and the
         Lenders hereby authorize such renewal, and, accordingly, the Issuer
         shall be deemed to have received an L/C Amendment Application from
         the Company requesting such renewal.

                  (e)  The Issuer may, at its election (or as required by the
         Agent at the direction of the Required Revolving Lenders) and upon
         reasonable prior written notice to the Company and subject to the terms
         of the applicable Letter of Credit, deliver any notices of termination
         or other communications to any Letter of Credit beneficiary or
         transferee, and take any other action as necessary or appropriate, at
         any time and from time to time, in order to cause the expiry date of
         such Letter of Credit to be a date not later than the date which is
         five days prior to the Revolving Loan Termination Date.

                  (f)  This Agreement shall control in the event of any
         conflict with any L/C-Related Document (other than any Letter of
         Credit).

                  (g)  The Issuer will also deliver to the Agent, concurrently
         or promptly following its delivery of a Letter of Credit, or amendment
         to or renewal of a Letter of Credit, to an advising bank or a
         beneficiary, a true and complete copy of each such Letter of Credit
         or amendment to or renewal of a Letter of Credit.

         3.03  RISK PARTICIPATIONS, DRAWINGS AND REIMBURSEMENTS. (a) Immediately
upon the Issuance of each Letter of Credit, each Revolving Lender shall be
deemed to, and hereby irrevocably and unconditionally agrees to, purchase from
the Issuer a participation in such Letter of Credit and each drawing thereunder
in an amount equal to the product of (i) the Pro Rata Revolving Share of such
Revolving Lender, times (ii) the maximum amount available to be drawn under such
Letter of Credit and the amount of such drawing, respectively. For purposes of
SUBSECTION 2.01(b), each Issuance of a Letter of Credit shall be deemed to
utilize

                                       51

<PAGE>

the Revolving Loan Commitment of each Revolving Lender by an amount equal to
the amount of such participation.

                  (b) In the event of any request for a drawing under a
         Letter of Credit by the beneficiary or transferee thereof, the
         Issuer will promptly notify the Company. The Company shall reimburse
         the Issuer prior to 11:00 a.m. (Central time), on each date that any
         amount is paid by the Issuer under any Letter of Credit (each such
         date, an "HONOR DATE"), in an amount in Dollars equal to the amount
         so paid by the Issuer. In the event the Company fails to reimburse
         the Issuer the full amount of any drawing under any Letter of Credit
         by 11:00 a.m. (Central time) on the Honor Date, the Issuer will
         promptly notify the Agent and the Agent will promptly notify each
         Lender thereof, and the Company shall be deemed to have requested
         that Base Rate Loans in an amount equal to such unreimbursed amount
         be made by the Revolving Lenders to be disbursed on the Honor Date
         under such Letter of Credit, subject to the amount of the unutilized
         portion of the Aggregate Revolving Loan Commitment and subject to
         the conditions set forth in SECTION 5.02. Any notice given by the
         Issuer or the Agent pursuant to this SUBSECTION 3.03(b) may be oral
         if immediately confirmed in writing (including by facsimile);
         provided that the lack of such an immediate confirmation shall not
         affect the conclusiveness or binding effect of such notice.

                  (c) Each Revolving Lender shall upon any notice pursuant to
         SUBSECTION 3.03(b) make available to the Agent for the account of the
         relevant Issuer an amount in Dollars and in immediately available funds
         equal to its Pro Rata Revolving Share of the Dollar Equivalent of the
         amount of the drawing, whereupon the participating Revolving Lenders
         shall (subject to SUBSECTION 3.03(d)) each be deemed to have made a
         Revolving Loan consisting of a Base Rate Loan to the Company in that
         amount. If any Revolving Lender so notified fails to make available to
         the Agent for the account of the Issuer the amount of such Revolving
         Lender's Pro Rata Share of the Dollar Equivalent of the amount of the
         drawing by no later than 1:00 p.m. (Central time) on the Honor Date,
         then interest shall accrue on such Revolving Lender's obligation to
         make such payment, from the Honor Date to the date such Revolving
         Lender makes such payment, at a rate per annum equal to the Federal
         Funds Rate in effect from time to time during such period. The Agent
         will promptly give notice of the occurrence of the Honor Date, but
         failure of the Agent to give any such notice on the Honor Date or in
         sufficient time to enable any Revolving Lender to effect such payment
         on such date shall not relieve such Revolving Lender from its
         obligations under this SECTION 3.03.

                  (d) With respect to any unreimbursed drawing that is not
         converted into Revolving Loans consisting of Base Rate Loans to the
         Company in whole or in part, because of the Company's failure to
         satisfy the conditions set forth in SECTION 5.02 or for any other
         reason, the Company shall be deemed to have incurred from the Issuer an
         L/C Borrowing in the Dollar Equivalent of the amount of such drawing,
         which L/C Borrowing shall be due and payable on demand (together with
         interest) and shall bear

                                       52

<PAGE>

         interest at a rate per annum equal to the Base Rate, plus the
         Applicable Base Rate Margin, plus 2.0% per annum, and each Revolving
         Lender's payment to the Issuer pursuant to SUBSECTION 3.03(c) shall
         be deemed payment in respect of its participation in such L/C
         Borrowing and shall constitute an L/C Advance from such Revolving
         Lender in satisfaction of its participation obligation under this
         SECTION 3.03.

                  (e) Each Revolving Lender's obligation in accordance with
         this Agreement to make the Revolving Loans or L/C Advances, as
         contemplated by this SECTION 3.03, as a result of a drawing under a
         Letter of Credit, shall be absolute and unconditional and without
         recourse to the Issuer and shall not be affected by any
         circumstance, including (i) any set-off, counterclaim, recoupment,
         defense or other right which such Revolving Lender may have against
         the Issuer, the Company or any other Person for any reason
         whatsoever; (ii) the occurrence or continuance of a Default, an
         Event of Default or a Material Adverse Effect; or (iii) any other
         circumstance, happening or event whatsoever, whether or not similar
         to any of the foregoing; PROVIDED, however, that each Revolving
         Lender's obligation to make Revolving Loans under this SECTION 3.03
         is subject to the conditions set forth in SECTION 5.02.

         3.04 REPAYMENT OF PARTICIPATIONS. (a) Upon (and only upon) receipt by
the Agent for the account of the Issuer of immediately available funds in
Dollars from the Company (i) in reimbursement of any payment made by the Issuer
under the Letter of Credit with respect to which any Revolving Lender has paid
the Agent for the account of the Issuer for such Revolving Lender's
participation in the Letter of Credit pursuant to SECTION 3.03 or (ii) in
payment of interest thereon, the Agent will promptly pay to each Revolving
Lender, in the same funds as those received by the Agent for the account of the
Issuer, the amount of such Revolving Lender's Pro Rata Revolving Share of such
funds, and the Issuer shall receive the amount of the Pro Rata Revolving Share
of such funds of any Revolving Lender that did not so pay the Agent for the
account of the Issuer.

                  (b) If the Agent or the Issuer is required at any time to
         return to the Company, or to a trustee, receiver, liquidator,
         custodian, or any official in any Insolvency Proceeding, any portion of
         the payments made by the Company to the Agent for the account of the
         Issuer pursuant to SUBSECTION 3.04(a) in reimbursement of a payment
         made under the Letter of Credit or interest or fee thereon, each
         Revolving Lender shall, on demand of the Agent, forthwith return to the
         Agent or the Issuer the amount of its Pro Rata Revolving Share of any
         amounts so returned by the Agent or the Issuer plus interest thereon
         from the date such demand is made to the date such amounts are returned
         by such Revolving Lender to the Agent or the Issuer, at a rate per
         annum equal to the Federal Funds Rate in effect from time to time.

         3.05 ROLE OF THE ISSUER. (a) Each Lender and the Company agree that, in
paying any drawing under a Letter of Credit, the Issuer shall not have any
responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of

                                       53

<PAGE>

Credit) or to ascertain or inquire as to the validity or accuracy of any such
document or the authority of the Person executing or delivering any such
document.

                  (b) No Agent-Related Person nor any of the respective
         correspondents, participants or assignees of the Issuer shall be liable
         to any Lender for: (i) any action taken or omitted in connection
         herewith at the request or with the approval of the Lenders (including
         the Required Lenders or Required Revolving Lenders, as applicable);
         (ii) any action taken or omitted in the absence of gross negligence or
         willful misconduct; or (iii) the due execution, effectiveness, validity
         or enforceability of any L/C-Related Document.

                  (c) The Company hereby assumes all risks of the acts or
         omissions of any beneficiary or transferee with respect to its use of
         any Letter of Credit; PROVIDED, however, that this assumption is not
         intended to, and shall not, preclude the Company's pursuing such rights
         and remedies as it may have against the beneficiary or transferee at
         law or under any other agreement. No Agent-Related Person, nor any of
         the respective correspondents, participants or assignees of the Issuer,
         shall be liable or responsible for any of the matters described in
         clauses (i) through (vii) of SECTION 3.06; PROVIDED, however, anything
         in such clauses to the contrary notwithstanding, that the Company may
         have a claim against the Issuer, and the Issuer may be liable to the
         Company, to the extent, but only to the extent, of any direct, as
         opposed to consequential or exemplary, damages suffered by the Company
         which the Company proves were caused by the Issuer's willful misconduct
         or gross negligence or the Issuer's willful failure to pay under any
         Letter of Credit after the presentation to it by the beneficiary of a
         sight draft and certificate(s) strictly complying with the terms and
         conditions of a Letter of Credit. In furtherance and not in limitation
         of the foregoing: (i) the Issuer may accept documents that appear on
         their face to be in order, without responsibility for further
         investigation, regardless of any notice or information to the contrary;
         and (ii) the Issuer shall not be responsible for the validity or
         sufficiency of any instrument transferring or assigning or purporting
         to transfer or assign a Letter of Credit or the rights or benefits
         thereunder or proceeds thereof, in whole or in part, which may prove to
         be invalid or ineffective for any reason.

         3.06     OBLIGATIONS ABSOLUTE.  The obligations of the Company under
this Agreement and any L/C-Related Document to reimburse the Issuer for a
drawing under a Letter of Credit, and to repay any L/C Borrowing and any
drawing under a Letter of Credit converted into Revolving Loans, shall be
unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement and each such other L/C-Related Document under
all circumstances, including the following:

                           (i)   any lack of validity or enforceability of
                  this Agreement or any L/C-Related Document;

                                       54

<PAGE>

                           (ii)  any material change in the time, manner or
                  place of payment of, or in any other material term of, all or
                  any of the obligations of the Company in respect of any
                  Letter of Credit or any other material amendment or waiver
                  of or any consent to material departure from all or any of the
                  L/C-Related Documents;

                           (iii) the existence of any claim, set-off, defense or
                  other right that the Company may have at any time against any
                  beneficiary or any transferee of any Letter of Credit (or any
                  Person for whom any such beneficiary or any such transferee
                  may be acting), the Issuer or any other Person, whether in
                  connection with this Agreement, the transactions contemplated
                  hereby or by the L/CRelated Documents or any unrelated
                  transaction;

                           (iv) any draft, demand, certificate or other document
                  presented under any 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;
                  or any loss or delay in the transmission or otherwise of any
                  document required in order to make a drawing under any Letter
                  of Credit;

                           (v) any payment by the Issuer under any Letter of
                  Credit against presentation of a draft or certificate that
                  does not strictly comply with the terms of any Letter of
                  Credit without the written consent of the Company; or any
                  payment made by the Issuer under any Letter of Credit to any
                  Person purporting to be a trustee in bankruptcy,
                  debtor-in-possession, assignee for the benefit of creditors,
                  liquidator, receiver or other representative of or successor
                  to any beneficiary or any transferee of any Letter of Credit,
                  including any arising in connection with any Insolvency
                  Proceeding;

                           (vi) any exchange, release or non-perfection of any
                  collateral, or any release or amendment or waiver of or
                  consent to departure from any other guarantee, for all or any
                  of the obligations of the Company in respect of any Letter of
                  Credit; or

                           (vii) any other circumstance or happening whatsoever,
                  whether or not similar to any of the foregoing, including any
                  other circumstance that might otherwise constitute a defense
                  available to, or a discharge of, the Company or a guarantor.

         3.07 CASH COLLATERAL PLEDGE. Upon (i) the request of the Agent, (A) if
the Issuer has honored any full or partial drawing request on any Letter of
Credit and such drawing has resulted in an L/C Borrowing hereunder, or (B) if,
as of the Revolving Loan Termination Date, any Letters of Credit may for any
reason remain outstanding and partially or wholly undrawn, (ii) the occurrence
of the circumstances described in SUBSECTION 2.09(a) requiring the

                                       55

<PAGE>

Company to Cash Collateralize Letters of Credit, or (iii) the termination of
the Aggregate Commitment, then, the Company shall immediately Cash
Collateralize the L/C Obligations in an amount equal to the L/C Obligations.

         3.08 LETTER OF CREDIT FEES. (a) The Company shall pay to the Agent
for the account of each of the Revolving Lenders a stand-by letter of credit
fee with respect to the Letters of Credit equal to the Applicable Offshore
Rate Margin for Revolving Loans times the average daily maximum amount
available to be drawn of the outstanding stand-by Letters of Credit, computed
on a quarterly basis in arrears on the last Business Day of each calendar
quarter based upon stand-by Letters of Credit outstanding for that quarter as
calculated by the Agent. Such stand-by letter of credit fees shall be due and
payable quarterly in arrears on the last Business Day of each calendar
quarter during which stand-by Letters of Credit are outstanding, commencing
on the first such quarterly date to occur after the Closing Date, through the
Revolving Loan Termination Date (or such later date upon which the
outstanding stand-by Letters of Credit shall expire), with the final payment
to be made on the Revolving Loan Termination Date (or such later expiration
date).

                  (b) The Company shall pay to the Agent for the account of each
         of the Revolving Lenders a Letter of Credit fee with respect to the
         commercial documentary Letters of Credit equal to 0.25% times the
         negotiated amount, payable at the time of each negotiation, as
         calculated by the Agent.

                  (c) The Company shall pay to the Issuer a letter of credit
         fronting fee for each Letter of Credit in an amount equal to the
         greater of 0.125% of the amount of each Letter of Credit or $300. Such
         Letter of Credit fronting fee shall be due and payable on each date
         of Issuance of a Letter of Credit.

                  (d) The Company shall pay to the applicable Issuer from time
         to time on demand the normal issuance, presentation, amendment and
         other processing fees, and other standard costs and charges, of such
         Issuer relating to letters of credit as from time to time in effect.

         3.09 PRIOR LETTERS OF CREDIT. In order to allow the Company to complete
the Fintube Acquisition, the Lenders agree to assume the responsibility for all
letters of credit previously issued on behalf of FLP as listed on the attached
SCHEDULE 3.09. Lenders direct Agent to issue at the Closing Letters of Credit
hereunder in conformity with the L/C Commitment hereunder to the issuers of the
letters of credit described on the attached SCHEDULE 3.09 in order to cause the
Lenders to assume all liability for such previously issued letters of credit.

         3.10 UNIFORM CUSTOMS AND PRACTICE. The Uniform Customs and Practice for
Documentary Credits as published by the International Chamber of Commerce most
recently at the time of issuance of any Letter of Credit shall (unless otherwise
expressly provided in the Letters of Credit) apply to the Letters of Credit.

                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         4.01 TAXES. (a) Any and all payments by the Company to each Lender
or the Agent under this Agreement and any other Loan Document shall be made
free and clear of, and without deduction or withholding for, any Taxes.  In
addition, the Company shall pay all Other Taxes.

                  (b) If the Company shall be required by law to deduct or
         withhold any Taxes, Other Taxes or Further Taxes from or in respect of
         any sum payable hereunder to any Lender or the Agent, then:

                           (i)   the sum payable shall be increased as necessary
                  so that, after making all required deductions and withholdings
                  (including deductions and withholdings applicable to
                  additional sums payable under this Section), such Lender or
                  the Agent, as the case may be, receives and retains an amount
                  equal to the sum it would have received and retained had no
                  such deductions or withholdings been made;

                           (ii)  the Company shall make such deductions and
                  withholdings;

                           (iii) the Company shall pay the full amount deducted
                  or withheld to the relevant taxing authority or other
                  authority in accordance with applicable law; and

                           (iv)  the Company shall also pay to each Lender or
                  the Agent for the account of such Lender, at the time interest
                  is paid, Further Taxes in the amount that the respective
                  Lender specifies as necessary to preserve the after-tax yield
                  the Lender would have received if such Taxes, Other Taxes or
                  Further Taxes had not been imposed.

                  (c) The Company agrees to indemnify and hold harmless each
         Lender and the Agent for the full amount of (i) Taxes, (ii) Other
         Taxes, and (iii) Further Taxes in the amount that the respective Lender
         reasonably specifies as necessary to preserve the after-tax yield the
         Lender would have received if such Taxes, Other Taxes or Further Taxes
         had not been imposed, and any liability (including penalties, interest,
         additions to tax and expenses) arising therefrom or with respect
         thereto, whether or not such Taxes, Other Taxes or Further Taxes were
         correctly or legally asserted; provided, however, that Agent shall, to
         the extent possible, notify the Company of the imposition of such Taxes
         and allow the Company the right to contest such Taxes, as long as the
         Company pays all expenses and costs associated therewith and the Taxes
         are, in the Agent's sole discretion, subject to being reasonably
         contested. Payment under this

                                       57

<PAGE>

         indemnification shall be made within 30 days after the date the Lender
         or the Agent makes written demand therefor.

                  (d) Within 30 days after the date of any payment by the
         Company of Taxes, Other Taxes or Further Taxes, the Company shall
         furnish to each Lender or the Agent the original or a certified
         copy of a receipt evidencing payment thereof, or other evidence
         of payment satisfactory to such Lender or the Agent.

                  (e) If the Company is required to pay any amount to any Lender
         or the Agent pursuant to subsection (b) or (c) of this Section, then
         such Lender shall use reasonable efforts (consistent with legal and
         regulatory restrictions) to change the jurisdiction of its Lending
         Office so as to eliminate any such additional payment by the Company
         which may thereafter accrue, if such change in the sole judgment of
         such Lender is not otherwise disadvantageous to such Lender.

         4.02 ILLEGALITY. (a) If any Lender determines that the introduction of
any Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Lender or its applicable Lending Office to make
Offshore Rate Loans, then, on notice thereof by the Lender to the Company
through the Agent, any obligation of that Lender to make Offshore Rate Loans
shall be suspended until the Lender notifies the Agent and the Company that the
circumstances giving rise to such determination no longer exist.

                  (b) If a Lender determines that it is unlawful to maintain any
         Offshore Rate Loan, the Company shall, upon its receipt of notice of
         such fact and demand from such Lender (with a copy to the Agent),
         prepay in full such Offshore Rate Loans of that Lender then
         outstanding, together with interest accrued thereon and amounts
         required under SECTION 4.04, either on the last day of the Interest
         Period thereof, if the Lender may lawfully continue to maintain such
         Offshore Rate Loans to such day, or immediately, if the Lender may not
         lawfully continue to maintain such Offshore Rate Loan. If the Company
         is required to so prepay any Offshore Rate Loan, then concurrently with
         such prepayment, the Company shall borrow from the affected Lender, in
         the amount of such repayment, a Base Rate Loan.

                  (c) If the obligation of any Lender to make or maintain
         Offshore Rate Loans has been so terminated or suspended, the Company
         may elect, by giving notice to the Lender through the Agent that all
         Loans which would otherwise be made by the Lender as Offshore Rate
         Loans shall be instead Base Rate Loans.

                  (d) Before giving any notice to the Agent under this Section,
         the affected Lender shall designate a different Lending Office with
         respect to its Offshore Rate

                                       58

<PAGE>

         Loans if such designation will avoid the need for giving such notice
         or making such demand and will not, in the judgment of the Lender,
         be illegal.

         4.03   INCREASED COSTS AND REDUCTION OF RETURN.  (a) If any Lender
determines that, due to either (i) the introduction of or any change (other
than any change by way of imposition of or increase in reserve requirements
included in the calculation of the Offshore Rate) in or in the interpretation
of any law or regulation or (ii) the compliance by that Lender with any
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to such Lender of agreeing to make or making, funding or maintaining any
Offshore Rate Loans or participating in Letters of Credit, or, in the case of
the Issuer, any increase in the cost to the Issuer of agreeing to issue,
issuing or maintaining any Letter of Credit or of agreeing to make or making,
funding or maintaining any unpaid drawing under any Letter of Credit, then
the Company shall be liable for, and shall from time to time, upon demand
(with a copy of such demand to be sent to the Agent), pay to the Agent for
the account of such Lender, additional amounts as are reasonably sufficient
to compensate such Lender for such increased costs.

                  (b) If any Lender shall have determined that (i) the
         introduction of any Capital Adequacy Regulation, (ii) any change in any
         Capital Adequacy Regulation, or (iii) any change in the interpretation
         or administration of any Capital Adequacy Regulation by any central
         bank or other Governmental Authority charged with the interpretation or
         administration thereof, or (iv) compliance by the Lender (or its
         Lending Office) or any corporation controlling the Lender with any
         Capital Adequacy Regulation, affects or would affect the amount of
         capital required or expected to be maintained by the Lender or any
         corporation controlling the Lender and (taking into consideration such
         Lender's or such corporation's policies with respect to capital
         adequacy and such Lender's desired return on capital) determines that
         the amount of such capital is materially increased as a consequence of
         its Commitment, loans, credits or obligations under this Agreement,
         then, upon demand of such Lender to the Company through the Agent, the
         Company shall pay to the Lender, from time to time as reasonably
         specified by the Lender, additional amounts reasonably sufficient to
         compensate the Lender for such increase.

         4.04     FUNDING LOSSES.  The Company shall reimburse each Lender
and hold each Lender harmless from any loss or expense which the Lender may
sustain or incur as a consequence of:

                  (a)  the failure of the Company to make on a timely basis
         any payment of principal of any Offshore Rate Loan;

                  (b)  the failure of the Company to borrow, continue or convert
         a Loan after the Company has given (or is deemed to have given) a
         Notice of Borrowing or a Notice of Conversion/ Continuation;

                                       59

<PAGE>

                  (c)  the failure of the Company to make any prepayment in
         accordance with any notice delivered under SECTION 2.08;

                  (d)  the prepayment (including pursuant to SECTION 2.09) or
         other payment (including after acceleration thereof) of an Offshore
         Rate Loan on a day that is not the last day of the relevant Interest
         Period other than any prepayment required pursuant to Section 4.02; or

                  (e) the automatic conversion under SECTION 2.04 of any
         Offshore Rate Loan to a Base Rate Loan on a day that is not the last
         day of the relevant Interest Period; including any such loss or
         expense arising from the liquidation or reemployment of funds
         obtained by it to maintain its Offshore Rate Loans or from fees
         payable to terminate the deposits from which such funds were
         obtained. For purposes of calculating amounts payable by the Company
         to the Lenders under this Section and under SUBSECTION 4.03(a), each
         Offshore Rate Loan made by a Lender (and each related reserve,
         special deposit or similar requirement) shall be conclusively deemed
         to have been funded at the LIBOR used in determining the Offshore
         Rate for such Offshore Rate Loan by a matching deposit or other
         borrowing in the interbank eurodollar market for a comparable amount
         and for a comparable period, whether or not such Offshore Rate Loan
         is in fact so funded.

         4.05 INABILITY TO DETERMINE RATES. If the Agent reasonably determines
that for any reason adequate and reasonable means do not exist for determining
the Offshore Rate for any requested Interest Period with respect to a proposed
Offshore Rate Loan, or that the Offshore Rate applicable pursuant to SUBSECTION
2.11(a) for any requested Interest Period with respect to a proposed Offshore
Rate Loan does not adequately and fairly reflect the cost to the Lenders of
funding such Loan, the Agent will promptly so notify the Company and each
Lender. Thereafter, the obligation of the Lenders to make or maintain Offshore
Rate Loans hereunder shall be suspended until the Agent revokes such notice in
writing. Upon receipt of such notice, the Company may revoke without cost or
penalty any Notice of Borrowing or Notice of Conversion/Continuation then
submitted by it. If the Company does not revoke such Notice, the Lenders shall
make, convert or continue the Loans, as proposed by the Company, in the amount

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants to the Agent and each Lender
that both before and after giving effect to the consummation of the
transactions contemplated by the Transaction Documents:

         6.01  CORPORATE EXISTENCE AND POWER.  The Company, ST Holdings and
each of its Material Subsidiaries:

                  (a) is a corporation duly organized, validly existing and in
         good standing under the laws of the jurisdiction of its incorporation;

                  (b) has the power and authority and all governmental licenses,
         authorizations, consents and approvals to own its assets, to carry on
         its business and to execute, deliver, and perform its obligations under
         the Transaction Documents to which it is a party;

                  (c) is duly qualified as a foreign corporation and is licensed
         and in good standing under the laws of each jurisdiction where its
         ownership, lease or operation of property or the conduct of its
         business requires such qualification or license; and

                  (d) is in compliance with all Requirements of Law; except, in
         each case referred to in clause (c) or clause (d), to the extent that
         the failure to do so could not reasonably be expected to have a
         Material Adverse Effect.

         6.02 CORPORATE AUTHORIZATION; NO CONTRAVENTION. The execution, delivery
and performance by the Company, its Subsidiaries, and ST Holdings of this
Agreement and each other Transaction Document to which such Person is party,
have been duly authorized by all necessary corporate action, and do not and
will not:

                  (a) contravene the terms of any of that Person's Organization
         Documents;

                  (b) conflict with or result in any breach or contravention of,
         or the creation of any Lien under, any document evidencing any
         Contractual Obligation to which such Person is a party other than the
         Transaction Documents or any order, injunction, writ or decree of any
         Governmental Authority to which such Person or its property is subject;
         or

                  (c) violate any Requirement of Law.

                                       68

<PAGE>

         6.03 GOVERNMENTAL AUTHORIZATION. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority (except those that have been obtained and remain in
effect and for recordings or filings in connection with the Liens granted to the
Agent under the Collateral Documents) is necessary or required in connection
with the execution, delivery or performance by, or enforcement against, the
Company or any of its Subsidiaries of the Agreement or any other Transaction
Document, except to the extent the failure to obtain such could not reasonably
be expected to have a Material Adverse Effect.

         6.04 BINDING EFFECT. This Agreement and each other Loan Document to
which the Company or any of its Subsidiaries or ST Holdings is a party
constitute the legal, valid and binding obligations of the Company, any of its
Subsidiaries and ST Holdings to the extent it is a party thereto, enforceable
against such Person in accordance with their respective terms, except as
enforceability may be limited by applicable bankruptcy, insolvency, or similar
laws affecting the enforcement of creditors' rights generally or by equitable
principles relating to enforceability.

         6.05 LITIGATION. There are no actions, suits, proceedings, claims or
disputes pending, or to the best knowledge of the Company, threatened or
contemplated, at law, in equity, in arbitration or before any Governmental
Authority, against the Company, or its Subsidiaries or ST Holdings or any of
their respective properties:

                  (a) which purport to affect or pertain to this Agreement or
         any other Transaction Document, or any of the transactions contemplated
         hereby or thereby; or

                  (b) except as disclosed on SCHEDULE 6.05, as to which there
         exists a substantial likelihood of an adverse determination, which
         determination could reasonably be expected to have a Material Adverse
         Effect. No injunction, writ, temporary restraining order or any order
         of any nature has been issued by any court or other Governmental
         Authority purporting to enjoin or restrain the execution, delivery or
         performance of this Agreement or any other Transaction Document, or
         directing that the transactions provided for herein or therein not be
         consummated as herein or therein provided.

         6.06 NO DEFAULT. No Default or Event of Default exists or would result
from the incurring of any Obligations by the Company or from the grant or
perfection of the Liens of the Agent and the Lenders on the Collateral. As of
the Closing Date, neither the Company nor any Subsidiary is in default under or
with respect to any Contractual Obligation in any respect which, individually or
together with all such defaults, could reasonably be expected to have a Material
Adverse Effect, or that would, if such default had occurred after the Closing
Date, create an Event of Default under SECTION 9.01.

         6.07  ERISA COMPLIANCE.  Except as specifically disclosed in SCHEDULE
6.07:

                                       69

<PAGE>

                  (a) Each Plan is in compliance in all material respects with
         the applicable provisions of ERISA, the Code and other federal or state
         law. Each Plan which is intended to qualify under Section 401(a) of the
         Code has received a favorable determination letter from the IRS and to
         the best knowledge of the Company, nothing has occurred which would
         cause the loss of such qualification. The Company and each ERISA
         Affiliate has made all required contributions to any Plan subject to
         Section 412 of the Code, and no application for a funding waiver or an
         extension of any amortization period pursuant to Section 412 of the
         Code has been made with respect to any Plan.

                  (b) There are no pending or, to the best knowledge of Company,
         threatened claims, actions or lawsuits, or action by any Governmental
         Authority, with respect to any Plan which has resulted or could
         reasonably be expected to result in a Material Adverse Effect. There
         has been no prohibited transaction or violation of the fiduciary
         responsibility rules with respect to any Plan which has resulted or
         could reasonably be expected to result in a Material Adverse Effect.

                  (c)               (i)  No ERISA Event has occurred or is
                           reasonably expected to occur; (ii) no Pension Plan
                           has any Unfunded Pension Liability; (iii) neither
                           the Company nor any ERISA Affiliate has incurred, or
                           reasonably expects to incur, any liability under
                           Title IV of ERISA with respect to any Pension Plan
                           (other than premiums due and not delinquent under
                           Section 4007 of ERISA);  (iv) neither the Company
                           nor any ERISA Affiliate has incurred, or reasonably
                           expects to incur, any liability (and no event has
                           occurred which, with the giving of notice under
                           Section 4219 of ERISA, would result in such
                           liability) under Section 4201 or 4243 of ERISA
                           with respect to a Multiemployer Plan; and (v)
                           neither the Company nor any ERISA Affiliate has
                           engaged in a transaction that could be subject
                           to Section 4069 or 4212(c) of ERISA.

         6.08 USE OF PROCEEDS; MARGIN REGULATIONS. The proceeds of the Loans are
to be used solely for the purposes set forth in and permitted by SECTION 7.12
and SECTION 8.07. Neither the Company nor any Subsidiary is generally engaged in
the business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock.

         6.09 TITLE TO PROPERTIES. The Company and each Material Subsidiary have
good record and marketable title in fee simple to, or valid leasehold interests
in, all real property necessary or used in the ordinary conduct of their
respective businesses, except for such defects in title as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. As of the Closing Date, the property of the Company and its
Subsidiaries is subject to no Liens, other than Permitted Liens.

                                       70

<PAGE>

         6.10 TAXES. The Company and its Subsidiaries have filed all Federal and
other material tax returns and reports required to be filed, and have paid all
Federal and other material taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets
otherwise due and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided in
accordance with GAAP. There is no proposed tax assessment against the Company or
any Subsidiary that would, if made, have a Material Adverse Effect.

         6.11 FINANCIAL CONDITION. (a) To the best of the Company's knowledge
the audited consolidated financial statements of FLP and its Subsidiaries dated
for fiscal years ended 1996, 1997 and 1998, and the related consolidated
statements of income or operations, shareholders' equity and cash flows for the
fiscal years ended on such dates and the unaudited consolidated financial
statements of FLP and its Subsidiaries dated September 30, 1999, and the related
consolidated statements of income or operations, shareholders' equity and cash
flows for the nine months ended on that date:

                           (i) were prepared in accordance with GAAP
                  consistently applied throughout the period covered thereby,
                  except for the absence of footnotes and as otherwise expressly
                  noted therein, subject, in the case of such unaudited
                  financial statements, to ordinary, good faith year end
                  adjustments;

                           (ii) fairly present the financial condition of the
                  FLP and its Subsidiaries, as applicable, as of the date
                  thereof and results of operations for the period covered
                  thereby; and

                           (iii) except as specifically disclosed in SCHEDULE
                  6.11 or SCHEDULE 8.08 show all material indebtedness and other
                  liabilities of the Company, its Subsidiaries, ST Holdings,
                  Fintube and its Subsidiaries, as applicable, as of the
                  date thereof.

                  (b) The unaudited Pro Forma Financial Statements are attached
         hereto as SCHEDULE 6.11. As of the date of the Agreement, the Pro Forma
         Financial Statements (other than the projections contained therein)
         fairly represent FLP and its Subsidiaries' assets, liabilities,
         financial condition and results of operations on a consolidated basis
         in accordance with GAAP (except for the absence of footnotes and
         statements of cash flow and recognizing such Pro Forma Financial
         Statements involve estimated purchase price accounting adjustments),
         consistently applied and taking into account the transactions
         contemplated by the Transaction Documents. The projections contained
         in the Pro Forma Financial Statements represent good faith estimates
         of the future financial performance of the Company and its
         Subsidiaries.

                  (c) Since September 30, 1999, there has been no Material
         Adverse Effect.

SCHEDULE 6.12, the on-going operations of the Company and each of its
Subsidiaries and ST Holdings comply in all respects with all Environmental Laws,
except such non-compliance which would not (if enforced in accordance with
applicable law) result in liability in excess of $1,000,000 in the aggregate
(exclusive of amounts payable under insurance policies and indemnity agreements
which the Company or such Subsidiary reasonably expects to receive).

                  (b) Except as specifically disclosed in SCHEDULE 6.12, the

         permits, authorizations and registrations required under any
         Environmental Law ("ENVIRONMENTAL PERMITS") and necessary for their
         respective ordinary course operations, except where the failure could
         not reasonably be expected to have a Material Adverse Effect, all such
         Environmental Permits are in good standing, and the Company and each of
         its Subsidiaries are in compliance with all material terms and
         conditions of such Environmental Permits.

                  (c) Except as specifically disclosed in SCHEDULE 6.12, none of
         the Company, any of its Subsidiaries or any of their respective present
         property or operations, is subject to any outstanding written order

         any judicial or docketed administrative proceeding, respecting any
         Environmental Law, Environmental Claim or Hazardous Material or (ii) to
         the extent that it could reasonably be expected to have a Material
         Adverse Effect, any claim, proceeding or written notice from any Person
         regarding any Environmental Law, Environmental Claim or Hazardous
         Material.

                  (d) Except as specifically disclosed in SCHEDULE 6.12, there
         are no Hazardous Materials or other conditions or circumstances
         existing with respect to any property of the Company or any Subsidiary,
         or arising from operations prior to the Closing Date, of the Company or
         any of its Subsidiaries that would reasonably be expected to give rise
         to Environmental Claims with a potential liability of the Company and
         its Subsidiaries in excess of $1,000,000 in the aggregate for all such
         conditions, circumstances and properties (exclusive of amounts payable
         under insurance policies and indemnity agreements which the Company or
         such Subsidiary reasonably expects to receive). Except as disclosed in
         SCHEDULE 6.12, (i) neither the Company nor any Subsidiary has any
         underground storage tanks (x) that are not properly registered or
         permitted under applicable Environmental Laws, or (y) that are leaking

         could reasonably be expected to have a Material Adverse Effect, and
         (ii) the Company and its Subsidiaries have met all material
         notification requirements under applicable Environmental Laws.

         6.13 COLLATERAL DOCUMENTS. (a) The provisions of each of the Collateral

Lenders, a legal, valid and enforceable first priority security interest in all
right, title and interest of the Company and its Subsidiaries in the collateral

                                       72

<PAGE>

                  (b) Each Mortgage when delivered will be effective to grant to
         the Agent for the benefit of the Lenders a legal, valid and enforceable
         lien on all the right, title and interest of the mortgagor under such
         Mortgage in the mortgaged property described therein. When each such
         Mortgage is duly recorded in the offices listed on the schedule to such
         Mortgage and the mortgage recording fees and taxes in respect thereof
         are paid and compliance is otherwise had with the formal requirements
         of state law applicable to the recording of real estate mortgages
         generally, each such mortgaged property, subject to the encumbrances
         and exceptions to title set forth therein and any Permitted Liens and
         except as noted in the title policies delivered to the Agent pursuant
         to SECTION 5.01, is subject to a legal, valid, enforceable and
         perfected first priority lien; and when financing statements have been
         filed in the offices specified in such Mortgage, such Mortgage also
         creates a legal, valid, enforceable and perfected first lien on, and
         security interest in, all right, title and interest of the Company or
         such Subsidiary under such Mortgage in all personal property and
         fixtures covered by such Mortgage, subject to no other Liens, except
         the encumbrances and exceptions to title set forth therein and except
         as noted in the title policies delivered to the Agent pursuant to
         SECTION 5.01, and Permitted Liens.

                  (c) All representations and warranties of the Company and any
         of its Subsidiaries party thereto contained in the Collateral Documents
         are true and correct.

         6.14  RESTRICTED ENTITIES.  None of the Company, any Person
controlling the Company, or any Subsidiary, is an "Investment Company" within
the meaning of the Investment Company Act of 1940.  The Company is not
subject to regulation under the Public Utility Holding Company Act of 1935,
the Federal Power Act, the Interstate Commerce Act, any state public
utilities code, or any other Federal or state statute or regulation limiting
its ability to incur Indebtedness.

         6.15  NO BURDENSOME RESTRICTIONS.  Neither the Company, ST Holdings
nor any Subsidiary is a party to or bound by any Contractual Obligation, or

         6.16  COPYRIGHTS, PATENTS, TRADEMARKS AND LICENSES, ETC. The
Company, ST Holdings and their Material Subsidiaries own or are licensed or
otherwise have the right to use all of the patents, trademarks, service
marks, trade names, copyrights, contractual franchises, authorizations and
other rights that are reasonably necessary for the operation of their
respective businesses, without conflict with the rights of any other Person,
except where the failure could not reasonably be expected to have a Material
Adverse Effect. To the best knowledge of the Company, no slogan or other
advertising device, product, process, method, substance, part or other
material now employed, or now contemplated to be employed, by the Company, ST
Holdings or any Subsidiary infringes upon any rights held by any other
Person. Except as specifically disclosed in SCHEDULE 6.16, no claim or
litigation regarding any of the

                                       73

<PAGE>

foregoing is pending or, to the knowledge of the Company, threatened, and no
patent, invention, device, application, principle or any statute, law, rule,
regulation, standard or code applicable to copyrights, patents, trademarks
and licenses is pending or, to the knowledge of the Company, proposed, which,
in either case, could reasonably be expected to have a Material Adverse
Effect.

Transaction Documents, the Company has no Subsidiaries other than those
specifically disclosed in part (a) of SCHEDULE 6.17 hereto and has no equity
investments in any other corporation or entity other than those specifically
disclosed in part (b) of SCHEDULE 6.17. The capitalization of the Company and
its Subsidiaries as of the Closing Date is as set forth on part (a) of
SCHEDULE 6.17.

         6.18 INSURANCE. Except as specifically disclosed in SCHEDULE 6.18,
the properties of the Company, ST Holdings and their respective Subsidiaries
are insured with financially sound and reputable insurance companies not
Affiliates of the Company, in such amounts, with such deductibles and
covering such risks as are customarily carried by companies engaged in
similar businesses and are similarly situated.

         6.19 SWAP OBLIGATIONS. Neither the Company, ST Holdings nor any of
its Subsidiaries has incurred any outstanding obligations under any Swap
Contracts, other than Permitted Swap Obligations. The Company has undertaken
its own independent assessment of its consolidated assets, liabilities and
commitments and has considered appropriate means of mitigating and managing
risks associated with such matters and has not relied on any swap
counterparty or any Affiliate of any swap counterparty in determining whether
to enter into any Swap Contract.

         6.20 ACQUISITION DOCUMENTS. The Company has delivered to the Agent
true, complete and correct copies of the Acquisition Documents (including all
schedules, exhibits, annexes, amendments, supplements, modifications and all
other material documents delivered pursuant thereto or in connection
therewith). The Acquisition Documents as originally executed and delivered by
the parties thereto have not been amended, waived, supplemented or modified
without the consent of the Agent. To the Company's knowledge, the
representations and warranties of the parties set forth therein are true and
correct in all material respects as of the date thereof. On the date of this
Agreement, neither the Company nor, to the Company's knowledge, any other
party to any of the Acquisition Documents is in default in the performance of

Fintube Acquisition is being consummated contemporaneously with the initial
Borrowing Date in accordance with applicable laws and regulations.

are Solvent.

         6.22 YEAR 2000 COMPLIANCE. The Company, ST Holdings and their
respective Subsidiaries have conducted a comprehensive review and assessment
of its computer applications, and have made inquiry of their material
suppliers, vendors and customers, with respect to any defect in computer
software, data bases, hardware, controls and peripherals related to the
occurrence of the year 2000 or the use of any date after December 31, 1999 in
connection therewith. Based on the foregoing review, assessment and inquiry,
the Company believes that no such defect could reasonably be expected to have
a Material Adverse Effect.

         6.23 FULL DISCLOSURE. None of the representations or warranties made
by the Company or any Subsidiary in the Loan Documents as of the date such
representations and warranties are made or deemed made, and none of the
statements contained in any exhibit, report, statement or certificate
furnished by or on behalf of the Company, ST Holdings or any of their
respective Subsidiaries in connection with the Loan Documents (including the
offering and disclosure materials delivered by or on behalf of the Company to
the Lenders prior to the Closing Date), contains any untrue statement of a
material fact or omits any material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they are made, not misleading as of the time when made or
delivered.

                                  ARTICLE VII

                             AFFIRMATIVE COVENANTS

         So long as any Lender shall have any Commitment hereunder, or any
Loan or other Obligation shall remain unpaid or unsatisfied, or any Letter of
Credit shall remain outstanding, unless the Required Lenders waive compliance
in writing:

         7.01 FINANCIAL STATEMENTS. The Company shall deliver to the Agent, in
form and detail satisfactory to the Agent and the Required Lenders, with
sufficient copies for each Lender:

                  (a) as soon as available, but not later than 90 days after the
         end of each fiscal year (commencing with the fiscal year ended December
         31, 2000), a copy of the audited consolidated balance sheet of the
         Company and its Subsidiaries as at the end of such year and the related
         consolidated statements of income, shareholders' equity and cash flows
         for such year, setting forth in each case in comparative form the
         figures for the previous fiscal year, and accompanied by the opinion of
         a nationally-recognized independent public accounting firm
         ("INDEPENDENT AUDITOR") reasonably acceptable to Agent which report
         shall state that such consolidated financial statements present fairly

         the applicable grace or notice period, if any, specified in the

         Indebtedness (or a trustee or agent on behalf of such holder or
         holders or beneficiary or beneficiaries) to cause such Indebtedness

         Guarantor or any other Person contests in any manner the validity or
         enforceability thereof or denies that it has any further liability or
         obligation thereunder; or any event described at subsections (f) or (g)
         of this Section occurs with respect to any Guarantor; or

                  (n) COLLATERAL.

                  enforceable against the Company or any Subsidiary party
                  thereto or the Company or any Subsidiary shall so state in
                  writing or bring an action to limit its obligations or
                  liabilities thereunder; or

                           (ii) any Collateral Document shall for any reason
                  (other than pursuant to the terms thereof) cease to create a
                  valid security interest in a material part of the Collateral
                  purported to be covered thereby or such security interest
                  shall for any reason cease to be a perfected and first
                  priority security interest subject only to Permitted Liens.

         9.02 REMEDIES.  If any Event of Default occurs, the Agent shall, at
the request of, or may, with the consent of, the Required Lenders,

                  (a) declare the Commitment of each Lender to make Loans and
         any obligation of the Issuer to Issue Letters of Credit to be
         terminated, whereupon such Commitments and obligation shall be
         terminated;

                  (b) declare an amount equal to the maximum aggregate amount
         that is or at any time thereafter may become available for drawing

         shall have presented, or shall be entitled at such time to present, the
         drafts or other documents required to draw under such Letters of
         Credit) to be immediately due and payable, and declare the unpaid
         principal amount of

                                       94

<PAGE>

         all outstanding Loans, all interest accrued and unpaid thereon, and
         all other amounts owing or payable hereunder or under any other Loan
         Document to be immediately due and payable, without presentment,
         demand, protest or other notice of any kind (except as otherwise
         expressly provided herein), all of which are hereby expressly waived
         by the Company; and

                  (c) exercise on behalf of itself and the Lenders all rights
         and remedies available to it and the Lenders under the Loan Documents
         or applicable law; PROVIDED, HOWEVER, that upon the occurrence of any
         event specified in subsection (f) or (g) of SECTION 9.01 (in the case
         of clause (i) of subsection (g) upon the expiration of the 60-day
         period mentioned therein), the obligation of each Lender to make Loans
         and any obligation of the Issuer to Issue Letters of Credit shall
         automatically terminate and the unpaid principal amount of all
         outstanding Loans and all interest and other amounts as aforesaid
         shall automatically become due and payable without further act of the
         Agent, the Issuer or any Lender.

         9.03 RIGHTS NOT EXCLUSIVE. The rights provided for in this Agreement
and the other Loan Documents are cumulative and are not exclusive of any
other rights, powers, privileges or remedies provided by law or in equity, or
under any other instrument, document or agreement now existing or hereafter
arising.

                                    ARTICLE X

                                    THE AGENT

         10.01 APPOINTMENT AND AUTHORIZATION; "AGENT". (a) Each Lender hereby
irrevocably (subject to SECTION 10.09) appoints, designates and authorizes the
Agent to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such duties
as are expressly delegated to it by the terms of this Agreement or any other
Loan Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Lender, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

<PAGE>

                  (b) Each Issuer shall act on behalf of the Lenders with
         respect to any Letters of Credit Issued by it and the documents
         associated therewith until such time and except for so long as the
         Agent may agree at the request of the Required Lenders to act for such
         Issuer with respect thereto; PROVIDED, HOWEVER, that such Issuer shall
         have all of the benefits and immunities (i) provided to the Agent in
         this ARTICLE X with respect to any acts taken or omissions suffered by
         the Issuer in connection with Letters of Credit Issued by it or
         proposed to be Issued by it and the application and agreements for
         letters of credit pertaining to the Letters of Credit as fully as if
         the term "Agent", as used in this ARTICLE X, included such Issuer with
         respect to such acts or omissions, and (ii) as additionally provided in
         this Agreement with respect to such Issuer.

         10.02 DELEGATION OF DUTIES. The Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties.  The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

         10.03 LIABILITY OF AGENT. None of the Agent-Related Persons shall (a)
be liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (b) be responsible in any manner to any of the Lenders for any recital,
statement, representation or warranty made by the Company or any Subsidiary or
Affiliate of the Company, or any officer thereof, contained in this Agreement or
in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or for the value of
or title to any Collateral, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of the Company or any other party to any Loan Document to
perform its obligations hereunder or thereunder. No Agent-Related Person shall
be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Company or any of the Company's Subsidiaries or
Affiliates.

         10.04 RELIANCE BY AGENT. (a) The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to the Company), independent accountants and other experts selected by the
Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate and, if it so requests, it shall first be indemnified to its

                                       96

<PAGE>

satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Required Lenders and such request and any action taken
or failure to act pursuant thereto shall be binding upon all of the Lenders.

                  (b) For purposes of determining compliance with the conditions
         specified in SECTION 5.01, each Lender that has executed this Agreement
         shall be deemed to have consented to, approved or accepted or to be
         satisfied with, each document or other matter either sent by the Agent
         to such Lender for consent, approval, acceptance or satisfaction, or
         required thereunder to be consented to or approved by or acceptable or
         satisfactory to such Lender.

         10.05 NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Lenders, unless the Agent shall
have received written 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". The Agent will notify the Lenders of its
receipt of any such notice. The Agent shall take such action with respect to
such Default or Event of Default as may be requested by the Required Lenders in
accordance with ARTICLE IX; PROVIDED, HOWEVER, that unless and until the Agent
has received any such request, the Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable or in the best interest
of the Lenders.

         10.06 CREDIT DECISION. Each Lender acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Lender. Each Lender represents to
the Agent that it has, independently and without reliance upon any AgentRelated
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, the value of and title to any Collateral, and all
applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to the Company hereunder. Each Lender also represents that it will,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Company. Except for notices, reports and other documents
expressly herein required to be furnished to the Lenders by the Agent, the Agent
shall not

                                       97

<PAGE>

have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of the Company which may
come into the possession of any of the Agent-Related Persons.

         10.07 INDEMNIFICATION OF AGENT. Whether or not the transactions
contemplated hereby are consummated, the Lenders shall indemnify upon demand
the Agent-Related Persons (to the extent not reimbursed by or on behalf of
the Company and without limiting the obligation of the Company to do so), in
accordance with such Lender's Pro Rata Share of all Loans and Commitments,
from and against any and all Indemnified Liabilities; PROVIDED, HOWEVER, that
no Lender shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified Liabilities resulting from such Person's gross
negligence or willful misconduct. Without limitation of the foregoing, each
Lender shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the
Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect
of rights or responsibilities under, this Agreement, any other Loan Document,
or any document contemplated by or referred to herein, to the extent that the
Agent is not reimbursed for such expenses by or on behalf of the Company. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Agent.

         10.08 AGENT IN INDIVIDUAL CAPACITY. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or an Issuer
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, BofA or its Affiliates may
receive information regarding the Company or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Company or such Subsidiary) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans, BofA
shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not the Agent or an Issuer.

         10.09 SUCCESSOR AGENT. The Agent may, and at the request of the
Required Lenders shall, resign as Agent upon 30 days' notice to the Lenders. If
the Agent resigns under this Agreement, the Required Lenders shall appoint from
among the Lenders a successor agent for the Lenders subject, so long as no Event
of Default has occurred and is then continuing, to the consent of the Company,
which shall not be unreasonably withheld or delayed. If no successor agent is
appointed prior to the effective date of the resignation of the Agent, the Agent
may appoint, after consulting with the Lenders and the Company, a successor
agent from among the Lenders. Upon the acceptance of its appointment as
successor agent hereunder, such successor agent shall succeed to all the rights,
powers and duties of the

                                       98

<PAGE>

retiring Agent and the term "Agent" shall mean such successor agent and the
retiring Agent's appointment, powers and duties as Agent shall be terminated.
After any retiring Agent's resignation hereunder as Agent, the provisions of
this ARTICLE X and SECTIONS 11.04 and 11.05 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under this
Agreement. If no successor agent has accepted appointment as Agent by the
date which is 30 days following a retiring Agent's notice of resignation, the
retiring Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Agent hereunder until
such time, if any, as the Required Lenders appoint a successor agent as
provided for above. Notwithstanding the foregoing, however, BofA may not be
removed as the Agent at the request of the Required Lenders unless BofA shall
also simultaneously be replaced as an "Issuer" (if any letters of credit
Issued by BofA are then outstanding) hereunder pursuant to documentation in
form and substance reasonably satisfactory to BofA.

         10.10 WITHHOLDING TAX. (a) (i) If any Lender is a "foreign corporation,
partnership or trust" within the meaning of the Code and such Lender claims
exemption from, or a reduction of U.S. withholding tax under Sections 1441 or
1442 of the Code, such Lender agrees with and in favor of the Agent and the
Company, to deliver to the Agent and the Company:

                  (A) if such Lender claims an exemption from, or a reduction
         of, withholding tax under a United States tax treaty, two properly
         completed and executed copies of IRS Form 1001 before the payment of
         any interest in the first calendar year and before the payment of any
         interest in each third succeeding calendar year during which interest
         may be paid under this Agreement;

                  (B) if such Lender claims that interest paid under this
         Agreement is exempt from United States withholding tax because it is
         effectively connected with a United States trade or business of such
         Lender, two properly completed and executed copies of IRS Form 4224
         before the payment of any interest is due in the first taxable year of
         such Lender and in each succeeding taxable year of such Lender during
         which interest may be paid under this Agreement; and

                  (C) such other form or forms as may be required under the Code
         or other laws of the United States as a condition to exemption from, or
         reduction of, United States withholding tax.

Such lender agrees to promptly notify the Agent and the Company of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

                  (ii) if any foreign Lender claims exemption from U.S. federal
         withholding tax under Section 871(h) or 881(c) of the Code with respect
         to payments of "portfolio interest", such Lender agrees with and in
         favor of the Agent and the Company to deliver to the Agent and the
         Company a Form W-8, or any subsequent versions thereof

                                       99

<PAGE>

         or successors thereto (and, if such Lender delivers a Form W-8, a
         certificate representing that such Lender is not a "bank" for purposes
         of Section 881(c) of the Code, is not a 10 percent shareholder (within
         the meaning of Section 871(h)(3)(B) of the Code) of the Company and is
         not a controlled foreign corporation related to the Company (within
         the meaning of Section 864(d)(4) of the Code)).

                  (b) If any Lender claims exemption from, or reduction of,
         withholding tax under a United States tax treaty by providing IRS Form
         1001 and such Lender sells, assigns, grants a participation in, or
         otherwise transfers all or part of the Obligations of the Company to
         such Lender, such Lender agrees to notify the Agent of the percentage
         amount in which it is no longer the beneficial owner of Obligations of
         the Company to such Lender. To the extent of such percentage amount,
         the Agent will treat such Lender's IRS Form 1001 as no longer valid.

                  (c) If any Lender claiming exemption from United States
         withholding tax by filing IRS Form 4224 with the Agent sells, assigns,
         grants a participation in, or otherwise transfers all or part of the
         Obligations of the Company to such Lender, such Lender agrees to
         undertake sole responsibility for complying with the withholding tax
         requirements imposed by Sections 1441 and 1442 of the Code.

                  (d) If any Lender is entitled to a reduction in the applicable
         withholding tax, the Agent may withhold from any interest payment to
         such Lender an amount equivalent to the applicable withholding tax
         after taking into account such reduction. However, if the forms or
         other documentation required by subsection (a) of this Section are not
         delivered to the Agent, then the Agent may withhold from any interest
         payment to such Lender not providing such forms or other documentation
         an amount equivalent to the applicable withholding tax imposed by
         Sections 1441 and 1442 of the Code, without reduction.

                  (e) If the IRS or any other Governmental Authority of the
         United States or other jurisdiction asserts a claim that the Agent did
         not properly withhold tax from amounts paid to or for the account of
         any Lender (because the appropriate form was not delivered or was not
         properly executed, or because such Lender failed to notify the Agent of
         a change in circumstances which rendered the exemption from, or
         reduction of, withholding tax ineffective, or for any other reason)
         such Lender shall indemnify the Agent fully for all amounts paid,
         directly or indirectly, by the Agent as tax or otherwise, including
         penalties and interest, and including any taxes imposed by any
         jurisdiction on the amounts payable to the Agent under this Section,
         together with all costs and expenses (including Attorney Costs). The
         obligation of the Lenders under this subsection shall survive the
         payment of all Obligations and the resignation or replacement of the
         Agent.

         Agent and payable under this Agreement or any other Loan Document; (ii)
         constituting property sold or to be sold or disposed of as part of or

         Agent at any time, the Lenders will confirm in writing the Agent's
         authority to release particular types or items of Collateral pursuant
         to this SUBSECTION 10.11(b), provided that the absence of any such
         confirmation for whatever reason shall not affect the Agent's rights
         under this SECTION 10.11.

                  (c) Each Lender agrees with and in favor of each other (which
         agreement shall not be for the benefit of the Company or any
         Subsidiary) that the Company's obligation to such Lender under this
         Agreement and the other Loan Documents is not and shall not be secured
         by any real property collateral now or hereafter acquired by such
         Lender other than the real property described in the Mortgages.

         purporting to be, a Person authorized by the Company to give such
         notice and the Agent and the Lenders shall not have any liability to
         the Company or other Person on account of any action taken or not taken

         the telephonic or facsimile notice.

         11.03 NO WAIVER; CUMULATIVE REMEDIES. No failure to exercise and no
delay in exercising, on the part of the Agent or any Lender, any right, remedy,

preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

nature whatsoever which may at any time (including at any time following
repayment of the Loans, the termination of the Letters of Credit and the

Lender or assignment by any Lender of its Loans or Commitments) be imposed on,
incurred by or asserted against any Indemnified Person in any way relating to or
arising out of this Agreement or any document contemplated by or referred to
herein, or the transactions contemplated hereby, or any action taken or omitted
by any such Person under or in connection with any of the foregoing, including
with respect to any investigation, litigation or proceeding (including any
Insolvency Proceeding or appellate proceeding) related to or arising out of this
Agreement or the Loans or Letters of Credit or the use of the proceeds thereof
or related to any Offshore Currency transactions entered into in connection
herewith, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "INDEMNIFIED LIABILITIES"); PROVIDED, that the

                                       104

<PAGE>

Company shall have no obligation hereunder to any Indemnified Person with
respect to Indemnified Liabilities resulting from the gross negligence or
willful misconduct of such Indemnified Person. The agreements in this Section
shall survive payment of all other Obligations.

                  (b) (i) The Company shall indemnify, defend and hold harmless
                  each Indemnified Person, from and against any and all
                  liabilities, obligations, losses, damages, penalties, actions,
                  judgments, suits, costs, charges, expenses or disbursements
                  (including Attorney Costs and the allocated cost of internal
                  environmental audit or review services), which may be incurred
                  by or asserted against such Indemnified Person in connection
                  with or arising out of any pending or threatened
                  investigation, litigation or proceeding, or any action
                  reasonably taken by any Person, with respect to any
                  Environmental Claim arising out of or related to any property,
                  whether or not subject to a Mortgage in favor of the Agent or
                  any Lender, or arising out of or related to any operations of
                  the Company or any Subsidiary. No action taken by legal
                  counsel chosen by the Agent or any Lender in defending against
                  any such investigation, litigation or proceeding or requested
                  remedial, removal or response action shall vitiate or in any
                  way impair the Company's obligation and duty hereunder to
                  indemnify and hold harmless the Agent and each Lender.

                           (ii) In no event shall any site visit, observation,
                  or testing by the Agent or any Lender (or any contractee of
                  the Agent or any Lender) be deemed a representation or
                  warranty that Hazardous Materials are or are not present in,
                  on, or under, the site, or that there has been or shall be
                  compliance with any Environmental Law. Neither the Company nor
                  any other Person is entitled to rely on any site visit,
                  observation, or testing by the Agent or any Lender. Neither
                  the Agent nor any Lender owes any duty of care to protect the
                  Company or any other Person against, or to inform the Company
                  or any other party of, any Hazardous Materials or any other
                  adverse condition affecting any site or property. The Agent or
                  any Lender may, at its discretion, disclose to the Company or
                  any other Person any report or findings made as a result of,
                  or in connection with, any site visit, observation, or testing
                  by the Agent or any Lender. The Company understands and agrees
                  that the Agent and the Lenders make no warranty or
                  representation to the Company or any other Person regarding
                  the truth, accuracy or completeness of any such report or
                  findings that may be disclosed. The Company also understands
                  that, depending upon the results of any site visit,
                  observation or testing by the Agent or any Lender and
                  disclosed to the Company, the Company may have a legal
                  obligation to notify one or more environmental agencies of the
                  results and that such reporting requirements are site-specific
                  and are to be evaluated by the Company without advice or
                  assistance from the Agent or any Lender.

<PAGE>

                  (c) Survival; Defense. The obligations in this Section shall
         survive payment of all other Obligations. At the election of any
         Indemnified Person, the Company shall defend such Indemnified Person
         using legal counsel reasonably satisfactory to such Indemnified Person
         in such Person's sole discretion, at the sole cost and expense of the
         Company. All amounts owing under this Section shall be paid within 30
         days after demand.

         11.06 MARSHALING; PAYMENTS SET ASIDE. Neither the Agent nor the
Lenders shall be under any obligation to marshall any assets in favor of the
Company or any other Person or against or in payment of any or all of the
Obligations. To the extent that the Company makes a payment to the Agent or
the Lenders, or the Agent or the Lenders exercise their right of set-off, and
such payment or the proceeds of such set-off or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Lender in its discretion) to be repaid to a trustee, receiver
or any other party, in connection with any Insolvency Proceeding or
otherwise, then (a) to the extent of such recovery the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such set-off
had not occurred, and (b) each Lender severally agrees to pay to the Agent
upon demand its pro rata share of any amount so recovered from or repaid by
the Agent.

         11.07 SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Company may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agent and each Lender.

         11.08 ASSIGNMENTS, PARTICIPATIONS, ETC. (a) Any Lender may, with the
written consent of the Company at all times other than during the existence of
an Event of Default and the Agent, the Swing Line Lender and, in respect of
assignments of Revolving Loans or a Revolving Loan Commitment, each Issuer with
an outstanding Letter of Credit, which consents shall not be unreasonably
withheld or delayed, at any time assign and delegate to one or more Eligible
Assignees (each an "ASSIGNEE") all, or any part of all, of the Loans, the
Commitments, the L/C Obligations and the other rights and obligations of such
Lender hereunder, in a minimum amount of $5,000,000 or if less, the total amount
of such Lender's outstanding Loans and/or Commitments (provided that (x) no
written consent of the Company, the Agent, the Swing Line Lender or any Issuer
shall be required in connection with any assignment and delegation by a Lender
to an Eligible Assignee that is an Affiliate of such Lender or any Approved
Fund, (y) no consent of the Swing Line Lender or any Issuer shall be required in
respect of any assignment and delegation consisting solely of Term Loans and (z)
assignments must be made ratably as between the Revolving Loans and the Term
Loans); PROVIDED, HOWEVER, that the Company and the Agent may continue to deal
solely and directly with such Lender in connection with the interest so assigned
to an Assignee until (i) written notice of such assignment, together with
payment instructions, addresses and related

                                       106

<PAGE>

information with respect to the Assignee, shall have been given to the
Company and the Agent by such Lender and the Assignee; (ii) such Lender and
its Assignee shall have delivered to the Company and the Agent an Assignment
and Acceptance in the form of EXHIBIT D ("ASSIGNMENT AND ACCEPTANCE")
together with any Note or Notes subject to such assignment and (iii) the
assignor Lender or Assignee has paid to the Agent a processing fee in the
amount of $3,500; PROVIDED, that in the case of contemporaneous assignments
by a Lender to more than one fund managed by the same investment advisor,
only a single fee of $3,500 shall be payable for all such contemporaneous
assignments.

                  (b) From and after the date that the Agent notifies the
         assignor Lender that it has received (and, if required, provided its
         consent with respect to) an executed Assignment and Acceptance and
         payment of the above-referenced processing fee, (i) the Assignee
         thereunder shall be a party hereto and, to the extent that rights and
         obligations hereunder (including without limitation any obligations
         under SECTION 10.11) have been assigned to it pursuant to such
         Assignment and Acceptance, shall have the rights and obligations of a
         Lender under the Loan Documents, and (ii) the assignor Lender shall,
         to the extent that rights and obligations hereunder and under the other
         Loan Documents have been assigned by it pursuant to such Assignment and
         Acceptance, relinquish its rights and be released from its obligations
         under the Loan Documents.

                  (c) Within five Business Days after its receipt of notice by
         the Agent that it has received an executed Assignment and Acceptance
         and payment of the processing fee, (and, if required, provided that it
         consents to such assignment in accordance with SUBSECTION 11.08(a)),
         the Company shall execute and deliver to the Agent new Notes evidencing
         such Assignee's assigned Loans and Commitment and, if the assignor
         Lender has retained a portion of its Loans and its Commitment,
         replacement Notes in the principal amount of the Loans retained by the
         assignor Lender (such Notes to be in exchange for, but not in payment
         of, the Notes held by such Lender). Immediately upon each Assignee's
         making its processing fee payment under the Assignment and Acceptance,
         this Agreement shall be deemed to be amended to the extent, but only to
         the extent, necessary to reflect the addition of the Assignee and the
         resulting adjustment of the Commitments arising therefrom. The
         Commitment allocated to each Assignee shall reduce such Commitments of
         the assigning Lender PRO TANTO.

                  (d) The Agent shall maintain a copy of each Assignment and
         Acceptance delivered to it and a register for the recordation of the
         names and addresses of the Lenders and the Commitments of, and
         principal amount of the Loans owing to, each Lender from time to time.
         The entries in such register shall be conclusive, in the absence of
         manifest error, and the Company, the Agent and the Lenders shall treat
         each person whose name is recorded in such register as the owner of the
         Commitments and the Loans recorded therein for all purposes of this
         Agreement. The register shall be

                                       107

<PAGE>

         available for inspection by the Company, any Lender and their
         representatives, at any reasonable time and from time to time upon
         reasonable prior notice.

                  (e) Any Lender may at any time sell to one or more commercial
         banks or other Persons not Affiliates of the Company (a "PARTICIPANT")
         participating interests in any Loans, the Commitment of that Lender and
         the other interests of that Lender (the "ORIGINATING LENDER") hereunder
         and under the other Loan Documents; PROVIDED, HOWEVER, that (i) the
         originating Lender's obligations under this Agreement shall remain
         unchanged, (ii) the originating Lender shall remain solely responsible
         for the performance of such obligations, (iii) the Company, each Issuer
         and the Agent shall continue to deal solely and directly with the
         originating Lender in connection with the originating Lender's rights
         and obligations under this Agreement and the other Loan Documents, and
         (iv) no Lender shall transfer or grant any participating interest under
         which the Participant has rights to approve any amendment to, or any
         consent or waiver with respect to, this Agreement or any other Loan
         Document, except to the extent such amendment, consent or waiver would
         require unanimous consent of the Lenders as described in clause (a)
         (but only in respect of any increase of any Commitment of any
         Originating Lender), (b) or (c) of the FIRST PROVISO to SECTION 11.01.
         In the case of any such participation, the Participant shall be
         entitled to the benefit of SECTIONS 4.01, 4.03 and 11.05 as though it
         were also a Lender hereunder, and if amounts outstanding under this
         Agreement are due and unpaid, or shall have been declared or shall
         have become due and payable upon the occurrence of an Event of
         Default, each Participant shall be deemed to have the right of
         set-off in respect of its participating interest in amounts owing
         under this Agreement to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under
         this Agreement.

                  (f) Notwithstanding any other provision in this Agreement, (i)
         any Lender may at any time create a security interest in, or pledge,
         all or any portion of its rights under and interest in this Agreement
         and the Notes held by it in favor of any Federal Reserve Bank in
         accordance with Regulation A of the FRB or U.S. Treasury Regulation 31
         CFR Section 203.14, and such Federal Reserve Bank may enforce such
         pledge or security interest in any manner permitted under applicable
         law and (ii) any Lender that is a fund that invests in bank loans may,
         without the consent of the Agent or the Company, pledge all or any
         portion of its rights under and interest in this Agreement to any
         trustee or to any other representative of holders of obligations owed
         or securities issued by such fund as security for such obligations or
         securities; PROVIDED, that any transfer to any Person upon the
         enforcement of such pledge or security interest may only be made
         subject to SECTION 11.08.

         11.09 CONFIDENTIALITY. Each Lender agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information provided to it by the Company or
any Subsidiary, or by the Agent on the

                                       108

<PAGE>

Company's or such Subsidiary's behalf, under this Agreement or any other Loan
Document, and neither it nor any of its Affiliates shall use any such
information other than in connection with or in enforcement of this Agreement
and the other Loan Documents or in connection with other business now or
hereafter existing or contemplated with the Company or any Subsidiary; except
to the extent such information (i) was or becomes generally available to the
public other than as a result of disclosure by the Lender or its Affiliates,
or (ii) was or becomes available on a non-confidential basis from a source
other than the Company, provided that such source is not bound by a
confidentiality agreement with the Company known to the Lender; PROVIDED,
HOWEVER, that any Lender may disclose such information (A) at the request or
pursuant to any requirement of any Governmental Authority to which the Lender
is subject or in connection with an examination of such Lender by any such
authority; (B) pursuant to subpoena or other court process; (C) when required
to do so in accordance with the provisions of any applicable Requirement of
Law; (D) to the extent reasonably required in connection with any litigation
or proceeding to which the Agent, any Lender or their respective Affiliates
may be party; (E) to the extent reasonably required in connection with the
exercise of any remedy hereunder or under any other Loan Document; (F) to
such Lender's independent auditors and other professional advisors; (G) to
any Participant or Assignee, actual or potential, provided that such Person
agrees in writing to keep such information confidential to the same extent
required of the Lenders hereunder; (H) as to any Lender or its Affiliate, as
expressly permitted under the terms of any other document or agreement
regarding confidentiality to which the Company or any Subsidiary is party or
is deemed party with such Lender or such Affiliate; (I) to its Affiliates;
and (J) to the National Association of Insurance Commissioners or any similar
organization or any nationally recognized rating agency that requires access
to information about such Lender's investment portfolio in connection with
ratings issued with respect to such Lender.

         11.10 SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Lender is authorized at any time and from time to time,
without prior notice to the Company, any such notice being waived by the Company
to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held by, and other indebtedness at any time owing by, such Lender to or for the
credit or the account of the Company against any and all Obligations owing to
such Lender, now or hereafter existing, irrespective of whether or not the Agent
or such Lender shall have made demand under this Agreement or any Loan Document
and although such Obligations may be contingent or unmatured. Each Lender agrees
promptly to notify the Company and the Agent after any such set-off and
application made by such Lender; PROVIDED, HOWEVER, that the failure to give
such notice shall not affect the validity of such set-off and application.

         11.11    AUTOMATIC DEBITS OF FEES.  With respect to any commitment
fee, arrangement fee, letter of credit fee or other fee, or any other cost or
expense (including Attorney Costs) due and payable to the Agent, any Issuer,
BofA or under the Loan Documents, the Company hereby irrevocably authorizes
BofA to debit any deposit account of the Company with BofA in

                                      109

<PAGE>

an amount such that the aggregate amount debited from all such deposit
accounts does not exceed such fee or other cost or expense; PROVIDED, that so
long as no Event of Default has occurred and is continuing, BofA has given
notice to the Company thereof not later than 9:00 a.m. (Central time) on the
date of such debit. If there are insufficient funds in such deposit accounts
to cover the amount of the fee or other cost or expense then due, such debits
will be reversed so as not to create an overdraft (in whole or in part, in
BofA's sole discretion) and such amount not debited shall be deemed to be
unpaid. No such debit under this Section shall be deemed a set-off.

         11.12 NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC. Each Lender
shall notify the Agent in writing of any changes in the address to which notices
to the Lender should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

         11.13 COUNTERPARTS. This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

         11.14 SEVERABILITY. The illegality or unenforceability of any provision
of this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

         11.15 NO THIRD PARTIES BENEFITTED. This Agreement is made and entered
into for the sole protection and legal benefit of the Company, the Lenders, the
Agent and the AgentRelated Persons, and their permitted successors and assigns,
and no other Person shall be a direct or indirect legal beneficiary of, or have
any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

         11.16 GOVERNING LAW AND ARBITRATION.

                  (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF OKLAHOMA (WITHOUT
         REGARD TO PRINCIPLES OF CONFLICTS OF LAW OF THAT STATE); PROVIDED
         HOWEVER ANY ISSUE OR ISSUES RELATING TO THE AMOUNT OR RATE OF INTEREST
         THAT MAY BE LAWFULLY CONTRACTED FOR, CHARGED, TAKEN, RESERVED, OR
         RECEIVED HEREUNDER OR UNDER ANY OF THE OTHER LOAN DOCUMENTS SHALL BE
         GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
         OKLAHOMA; PROVIDED FURTHER THAT THE ADMINISTRATIVE AGENT AND THE BANKS
         SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

                                       110

<PAGE>

                  (b) ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE
         PARTIES HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR
         RELATING TO THIS AGREEMENT, OR ANY RELATED AGREEMENT OR INSTRUMENTS,
         INCLUDING ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT, SHALL BE
         DETERMINED BY BINDING ARBITRATION IN ACCORDANCE WITH THE FEDERAL
         ARBITRATION ACT (OR IF NOT APPLICABLE, THE APPLICABLE STATE LAW), THE
         RULES OF PRACTICE AND PROCEDURE FOR THE ARBITRATION OF COMMERCIAL
         DISPUTES OF J.A.M.S./ENDISPUTE OR ANY SUCCESSOR THEREOF ("J.A.M.S.")
         AND THE "SPECIAL RULES" SET FORTH BELOW. IN THE EVENT OF ANY
         INCONSISTENCY, THE SPECIAL RULES SHALL CONTROL. JUDGMENT UPON ANY
         ARBITRATION AWARD MAY BE ENTERED IN ANY COURT HAVING JURISDICTION. ANY
         PARTY TO THIS AGREEMENT MAY BRING AN ACTION, INCLUDING A SUMMARY OR
         EXPEDITED PROCEEDING, TO COMPEL ARBITRATION OF ANY CONTROVERSY OR CLAIM
         TO WHICH THIS AGREEMENT APPLIES IN ANY COURT HAVING JURISDICTION OVER
         SUCH ACTION.

                   SPECIAL RULES. THE ARBITRATION SHALL BE CONDUCTED IN THE
         COUNTY OF TULSA, OKLAHOMA AND ADMINISTERED BY J.A.M.S WHO WILL APPOINT
         AN ARBITRATOR; IF J.A.M.S. IS UNABLE OR LEGALLY PRECLUDED FROM
         ADMINISTERING THE ARBITRATION, THEN THE AMERICAN ARBITRATION
         ASSOCIATION WILL SERVE. ALL ARBITRATION HEARINGS WILL BE COMMENCED
         WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION; FURTHER THE ARBITRATOR
         SHALL ONLY, UPON A SHOWING OF CAUSE, BE PERMITTED TO EXTENT THE
         COMMENCEMENT OF SUCH HEARING FOR UP TO AN ADDITIONAL 60 DAYS.

                   RESERVATION OF RIGHTS. NOTHING IN THIS ARBITRATION PROVISION
         SHALL BE DEEMED TO (I) LIMIT THE APPLICABILITY OF ANY OTHERWISE
         APPLICABLE STATUTES OF LIMITATIONS OR REPOSE AND ANY WAIVERS CONTAINED
         IN THIS INSTRUMENT, AGREEMENT OR DOCUMENT; OR (II) BE A WAIVER BY ANY
         LENDER OR THE AGENT, OF THE PROTECTION AFFORDED TO THEM BY 12 U.S.C.
         SEC. 91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT THE
         RIGHT OF ANY LENDER OR THE AGENT HERETO (A) TO EXERCISE SELF HELP
         REMEDIES SUCH AS (BUT NOT LIMITED TO) SETOFF OR (B) TO FORECLOSE
         AGAINST ANY REAL OR PERSONAL PROPERTIES COLLATERAL, OR (C) TO OBTAIN
         FROM A COURT PROVISIONAL OR ANCILLARY REMEDIES SUCH AS (BUT NOT LIMITED
         TO) INJUNCTIVE RELIEF, WRIT OF POSSESSION OR THE APPOINTMENT OF A
         RECEIVER,

                                     111

<PAGE>

         THE AGENT MAY EXERCISE SUCH SELF HELP RIGHTS, FORECLOSE UPON SUCH
         PROPERTY OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES BEFORE,
         DURING OR AFTER THE PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT
         PURSUANT TO THIS INSTRUMENT, AGREEMENT OR DOCUMENT. NEITHER THIS
         EXERCISE OF SELF HELP REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN
         ACTION FOR FORECLOSURE OR PROVISIONAL OR ANCILLARY REMEDIES SHALL
         CONSTITUTE A WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE CLAIMANT
         IN ANY SUCH ACTION, TO ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM
         OCCASIONING RESORT TO SUCH REMEDIES.

                  IN THE EVENT THAT THE FOREGOING ARBITRATION PROVISION IS NOT
         UPHELD FOR ANY REASON AND THE PARTIES RESORT TO A COURT OF LAW TO
         SETTLE THEIR DISPUTE, EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY
         WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND OR CAUSE OF
         ACTION ARISING UNDER THIS AGREEMENT OR ANY OF THE LOAN DOCUMENTS, OR IN
         ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE
         PARTIES HERETO WITH RESPECT TO THIS AGREEMENT OR THE LOAN DOCUMENTS,
         OR THE TRANSACTIONS RELATED HERETO OR THERETO, WHETHER NOW EXISTING
         OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
         OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH
         CLAIM, DEMAND OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL
         WITHOUT A JURY, AND THAT ANY PARTY MAY FILE AN ORIGINAL COUNTERPART OR
         COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE
         CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY
         JURY.

         11.17 ENTIRE AGREEMENT. (a) This Agreement, together with the other
Loan Documents, embodies the entire agreement and understanding among the
Company, the Lenders and the Agent, and supersedes all prior or contemporaneous
agreements and understandings of such Persons, verbal or written, relating to
the subject matter hereof and thereof.
