Interest Period therefor, the rate per annum (rounded upwards, if necessary, to
the nearest 1/100 of 1%) determined by Administrative Agent to be equal to the

for such Eurodollar Borrowing for such Interest Period.

successors and assigns as "Administrative Agent" for Lenders under this
Agreement.

         APPLICABLE LENDING OFFICE means, for each Lender and for each Type of

         2.2 SWING LINE SUBFACILITY.

         (a) For the convenience of the parties and as an integral part of the
transactions contemplated by the Loan Documents, Swing Line Lender, solely for
its own account, agrees to make any requested Swing Line Borrowing of $5,000,000
or a greater integral multiple of $1,000,000, subject to those terms and
conditions applicable to Borrowings set forth in SECTION 6, directly to Borrower
as a Swing Line Borrowing without requiring any other Lender to fund its Pro
Rata Part thereof unless and until SECTION 2.2(b) is applicable; provided that:
(i) each Swing Line Borrowing must occur on a Business Day and no later than the
Business Day immediately preceding the Termination Date; (ii) the aggregate
Swing Line Principal Debt outstanding on any date of determination shall not
exceed the lesser of (A) the Swing Line Commitment, and (B) the Total Commitment
minus the Total Principal Debt (other than the Swing Line Principal Debt); (iii)
on any date of determination, the Total Principal Debt shall never exceed the

Commitment then in effect; and (v) no additional Swing Line Borrowing shall be
made at any time after any Lender has refused, notwithstanding the requirements
of SECTION 2.2(b), to purchase a participation in any Swing Line Borrowing as
provided in such SECTION, until such purchase shall occur or until the Swing
Line Borrowing has been repaid. Borrower may request a Swing Line Borrowing on
any Business Day by telephonic notice to Swing Line Lender no later than 12:00
noon on such Business Day (followed immediately by a Notice of Borrowing), and
Swing Line Lender shall make such Swing Line Borrowing available to Borrower in
immediately available funds (by deposit of such funds to Borrower's account as
designated to Administrative Agent by Borrower) within two hours of receipt of
the Notice of Borrowing, provided that such Notice of Borrowing is received by
Swing Line Lender not later than 2:00 p.m. Each

                                       16
<PAGE>   23

(with written Notice of Prepayment to promptly follow) from Borrower to Swing
Line Lender, so long as such telephonic notice is received by Swing Line Lender

         (b) Upon the occurrence of an Event of Default or in the event that any
Swing Line Borrowing shall be outstanding for more than five (5) Business Days,
Administrative Agent shall, on behalf of Borrower (which hereby irrevocably
directs and authorizes Administrative Agent to act on its behalf), request a
Prime Rate Borrowing from Lenders (and each Lender shall fund its Pro Rata Part
thereof) in an amount equal to the Swing Line Principal Debt outstanding under
such Swing Line Borrowing. The proceeds of such Prime Rate Borrowing shall be
immediately applied to repay such Swing Line Borrowing. If any Lender does not
promptly pay such amount upon Administrative Agent's demand therefor, and until
such time as such Lender makes the required Borrowing, Swing Line Lender shall
be deemed to continue to have outstanding its Swing Line Borrowing in the amount
of such unpaid obligation. If Borrower fails to repay any Swing Line Borrowing
within five (5) Business Days, and funds cannot be or are not advanced under
this Agreement to satisfy the obligations under the Swing Line Subfacility,
Administrative Agent shall timely notify each Lender of such failure and of the
date and amount not paid. No later than the close of business on the date such
notice is given (if such notice was given prior to 10:00 a.m., on any Business
Day, or, if made at any other time, on the next Business Day following the date
of such notice), each Lender shall be deemed to have irrevocably and
unconditionally purchased and received from Swing Line Lender an undivided
interest and participation in such Swing Line Borrowing to the extent of such
Lender's Pro Rata Part (with respect to this Agreement) thereof, and each Lender
shall make available to Swing Line Lender in immediately available funds such
Lender's Pro Rata Part (with respect to this Agreement) of the unpaid amount of
such Swing Line Borrowing. All such amounts payable by any Lender shall include
interest thereon from the date on which such payment is payable by such Lender
to, but not including, the date such amount is paid by such Lender to
Administrative Agent, at the Federal Funds Rate. If such Lender does not
promptly pay such amount upon Administrative Agent's demand therefor, and until
such time as such Lender makes the required payment, then Swing Line Lender
shall be deemed to continue to have outstanding a Swing Line Borrowing in the
amount of such unpaid obligation. Each payment by Borrower of all or any part of
any Swing Line Borrowing shall be paid to Administrative Agent for the ratable
benefit of Swing Line Lender and those Lenders who have funded their
participations in such Swing Line Principal Debt under this SECTION 2.2(b);
provided that, with respect to any such participation, all interest accruing on
the Swing Line Principal Debt to which such participation relates prior to the
date of funding such participation shall be payable solely to Swing Line Lender
for its own account. In the event that any payment received by Swing Line Lender
is required to be returned, each Lender will return to Swing Line Lender any
portion thereof previously distributed by Swing Line Lender to it.

         (c) Notwithstanding anything to the contrary in this Agreement, each
Lender's obligation to fund the Borrowings and to purchase and fund
participating interests pursuant to SECTION 2.2(b) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without
limitation, (i) any setoff, counterclaim, recoupment, defense, or other Right
which such Lender or Borrower may have against the Swing Line Lender, Borrower,
or any other Person for any reason whatsoever; (ii) the occurrence or
continuance of a Potential Default or an Event of Default or the failure to
satisfy any of the conditions specified in SECTION 6; (iii) any adverse change
in the condition (financial or otherwise) of any Company; (iv) any breach of
this Agreement by Borrower or any Credit Party; or (v) any other circumstance,
happening, or event whatsoever, whether or not similar to any of the foregoing.

         Total Commitment does not exceed $750,000,000;

                  (E) each increase in the Total Commitment shall be in the
         amount of $10,000,000 or a greater integral multiple of $500,000;

                  (F) no admission of any Subsequent Lender shall increase the
         Commitment of any existing Lender without the written consent of such
         Lender;

         aggregate.

After the admission of any Subsequent Lender or the increase in the Commitment
of any Increasing Lender, Administrative Agent shall promptly provide to each
Lender and to Borrower a new SCHEDULE 2.1 to this Agreement.

         (c) Notwithstanding anything to the contrary set forth above, at all
times prior to the Tranche B Termination Date, the additional Commitment of any
and all Subsequent Lenders or Increasing Lenders shall be applied as a Pro Rata
permanent termination of the Tranche B Commitments, and, if any Principal Debt
is outstanding at the time of such additional Commitment, each Tranche B Lender
and the Subsequent Lender or Increasing Lender (as the case may be) shall,
concurrently with such additional Commitment, execute and deliver an Assignment
and Acceptance Agreement in the form of EXHIBIT E pursuant to which such Tranche
B Lender shall assign to the Subsequent Lender or Increasing Lender a
proportionate part of such Tranche B Lender's Tranche B Principal Debt (based on
the percentage obtained by dividing (i) the amount of the additional Commitment
replacing such Tranche B Lender's Tranche B Commitment, by (ii) the amount of
such Tranche B Lender's total Tranche B Commitment in effect immediately prior
to such

                                       18
<PAGE>   25

be considered Tranche B Principal Debt for any purpose of this Agreement but

Increasing Lender evidenced by such Lender' s new or replacement Revolving Note.

the Total Principal Debt; and (c) prior to the Tranche B Termination Date, each
reduction shall be first allocated Pro Rata among the Tranche B Lenders in
accordance with their respective Pro Rata Parts until the total Tranche B
Commitment is reduced to $0, and then shall be allocated Pro Rata among the
Lenders in accordance with their respective Pro Rata Parts, and, on and after
the Tranche B Termination Date, each reduction shall be allocated Pro Rata among
Lenders in accordance with their respective Pro Rata Parts. Promptly after
receipt of such notice of termination or reduction, Administrative Agent shall
notify each Lender of the proposed cancellation or reduction. Such termination
or partial reduction of the Total Commitment shall be effective on the Business
Day specified in Borrower's notice (which date must be at least ten (10)

p.m. on the Borrowing Date to Borrower's account as designated to Administrative
Agent by Borrower. Notwithstanding the foregoing, unless Administrative Agent
shall have been notified by a Lender prior to a Borrowing Date that such Lender
does not intend to make available to Administrative Agent such Lender's Pro Rata
Part of the applicable Borrowing, Administrative Agent may assume that such
Lender has made such proceeds available to Administrative Agent on such date, as
required herein, and Administrative Agent may (unless to its actual knowledge
any of the conditions precedent therefor have not been satisfied by Borrower or
waived by Required Lenders), in reliance upon such assumption (but shall not be
required to), make available to Borrower a corresponding amount in accordance

                                       19
<PAGE>   26

with the foregoing terms, but, if such corresponding amount is not in fact made
available to Administrative Agent by such Lender on such Borrowing Date, then
Administrative Agent shall be entitled to recover such corresponding amount on
demand (i) from such Lender, together with interest at the Federal Funds Rate
during the period commencing on the date such corresponding amount was made
available to Borrower and ending on (but excluding) the date Administrative
Agent recovers such corresponding amount from such Lender, or (ii) if such
Lender fails to pay such corresponding amount forthwith upon such demand, then
from Borrower, together with interest at a rate per annum equal to the
applicable rate for such Borrowing during the period commencing on such
Borrowing Date and ending on (but excluding) the date Administrative Agent
recovers such corresponding amount from Borrower. No Lender shall be responsible
for the failure of any other Lender to make its Pro Rata Part of any Borrowing.

         2.6 EXTENSION OF TRANCHE B COMMITMENTS. Upon thirty (30) days prior
written request by Borrower, any Tranche B Lender may agree in its sole
discretion to extend the Tranche B Termination Date with respect to its Tranche
B Commitment (which extension must be approved by Administrative Agent, such
approval not to be unreasonably withheld) for an additional one (1) year period
and all of the terms and provisions set forth in this Agreement shall apply to
such Tranche B Commitment as extended.

SECTION 3 TERMS OF PAYMENT.

         3.1 NOTES AND PAYMENTS.

         (a) NOTES. The Principal Debt (other than the Swing Line Principal
Debt) owed to each Lender shall be evidenced by the Revolving Notes, one payable
to each Lender in the maximum stated principal amount of its Commitment (other
than the Tranche B Commitment) and, if applicable, the Tranche B Notes, one
payable to each Tranche B Lender in the maximum stated principal amount of its
Tranche B Commitment. The Swing Line Principal Debt shall be evidenced by the
Swing Line Note.

         (b) PAYMENTS GENERALLY. Each payment or prepayment on the Obligation is
due and must be paid by Borrower to Administrative Agent at its Payment Office
in Dollars and in immediately available funds, without set-off, deduction, or
counterclaim, by 10:00 a.m. on the day due. Payments made after 10:00 a.m. shall
be deemed made on the Business Day next following. Administrative Agent shall
pay to each Lender any payment or prepayment to which such Lender is entitled
hereunder on the same day Administrative Agent shall have received the same from
Borrower; provided that such payment or prepayment is received by Administrative
Agent prior to 10:00 a.m., and otherwise before 10:00 a.m. on the Business Day
next following. If and to the extent Administrative Agent shall not make such
payments to Lenders when due as set forth in the preceding sentence, then such
unpaid amounts shall accrue interest, payable by Administrative Agent, at the
Federal Funds Rate from the due date until (but not including) the date on which
Administrative Agent makes such payments to Lenders.

         3.2 INTEREST AND PRINCIPAL PAYMENTS.

         (a) INTEREST PAYMENTS. Interest on each Eurodollar Borrowing shall be
due and payable as it accrues on the last day of its respective Interest Period
and on the Termination Date, as applicable; provided that, with respect to
Eurodollar Borrowings having an Interest Period in excess of three (3) months,
Borrower shall pay interest quarterly in arrears on the last Business Day of
each March, June, September, and December, commencing on the first (1st) such
date after the date on which such Interest Period commences and continuing on
the last Business Day of each March, June, September, and December thereafter
and on

                                       20
<PAGE>   27

the expiration of each Interest Period. Interest on each Prime Rate Borrowing
shall be due and payable as it accrues on each March 31, June 30, September 30,
and December 31, and on the Termination Date. Interest on each Swing Line
Borrowing shall be due and payable on the date that Borrower repays such Swing
Line Borrowing (with the proceeds of another Borrowing hereunder or otherwise).

         (b) MANDATORY PAYMENTS.

                  (i) The Total Principal Debt (other than the Swing Line
         Principal Debt) is due and payable on the Termination Date. The Swing
         Line Principal Debt shall be due and payable as provided in SECTION 2.2
         and on the Termination Date. The Tranche B Principal Debt is due and
         payable on the Tranche B Termination Date.

                  (ii) On any date of determination, if the Total Principal Debt
         exceeds the Total Commitment, then Borrower shall prepay the Principal
         Debt in at least the amount of such excess, together with (A) all
         accrued and unpaid interest on the Principal Debt prepaid, and (B) any
         Consequential Loss arising as a result thereof.

                  (iii) All mandatory payments pursuant to this SECTION 3.2(b)
         shall be applied to the unpaid Principal Debt Pro Rata except as
         otherwise specifically provided herein.

         (c) VOLUNTARY PREPAYMENTS. Subject to the last sentence of SECTION
2.2(a), after giving Administrative Agent a Notice of Prepayment, Borrower may
voluntarily prepay all or any part of the Principal Debt from time to time and
at any time, in whole or in part, without premium or penalty; provided that: (i)
such notice must be received by Administrative Agent by 9:00 a.m. on (a) the
third (3rd) Business Day preceding the date of prepayment of a Eurodollar
Borrowing, and (b) one (1) Business Day prior to a prepayment of a Prime Rate
Borrowing; (ii) each such partial prepayment must be in the amount of $5,000,000
or a greater integral multiple of $1,000,000 (whether a Eurodollar Borrowing or
a Prime Rate Borrowing); (iii) all accrued interest on the Principal Debt being
prepaid must also be paid in full, to the date of such prepayment if such
voluntary prepayment is a prepayment of all outstanding Principal Debt and a
termination of all Commitments under this Agreement or if the Principal Debt
being prepaid is a Eurodollar Borrowing or a Swing Line Borrowing; and (iv)
Borrower shall pay any related Consequential Loss (for any Eurodollar Borrowing)
within ten (10) days after demand therefor. Each Notice of Prepayment shall
specify the prepayment date and the Type of Borrowing(s) and amount(s) of such
Borrowing(s) to be prepaid and shall constitute a binding obligation of Borrower
to make a prepayment on the date stated therein.

         3.3 INTEREST OPTIONS. Except where specifically otherwise provided,
Borrowings (other than Swing Line Borrowings) shall bear interest at a rate per
annum equal to the lesser of (a) as to the respective Type of Borrowing (as
designated by Borrower in accordance with this Agreement), the Prime Rate plus
the Applicable Margin for Prime Rate Borrowings or the Adjusted Eurodollar Rate
plus the Applicable Margin for Eurodollar Borrowings, and (b) the Maximum Rate.
Except as specifically otherwise provided, Swing Line Borrowings shall bear
interest at an annual rate equal to the Swing Line Rate. Each change in the
Prime Rate, Swing Line Rate, Applicable Margin, or the Maximum Rate, subject to
the terms of this Agreement, will become effective, without notice to Borrower
or any other Person, upon the effective date of such change.

         3.4 QUOTATION OF RATES. A Responsible Officer may call Administrative
Agent on or before the date on which a Notice of Borrowing is to be delivered by
Borrower in order to receive an indication of

                                       21

<PAGE>   28

the rates then in effect, but such indicated rates shall neither be binding upon
Administrative Agent or Lenders nor affect the rate of interest which thereafter
is actually in effect when the Notice of Borrowing is given.

         3.5 DEFAULT RATE. At the option of Required Lenders at any time while
an Event of Default exists and to the extent permitted by all Legal
Requirements, all past due Principal Debt and all past due accrued interest
thereon, and fees and expenses payable hereunder and under the other Loan
Documents shall bear interest at the Default Rate until paid, regardless whether
such payment is made before or after entry of a judgment.

         3.6 INTEREST RECAPTURE. If the designated rate applicable to any
Borrowing exceeds the Maximum Rate, then the rate of interest on such Borrowing
shall be limited to the Maximum Rate, but any subsequent reductions in such
designated rate shall not reduce the rate of interest thereon below the Maximum
Rate until the total amount of interest accrued thereon equals the amount of
interest which would have accrued thereon if such designated rate had at all
times been in effect. In the event that at maturity (stated or by acceleration),
or at final payment of the Total Principal Debt, the total amount of interest
paid or accrued is less than the amount of interest which would have accrued if
such designated rates had at all times been in effect, then, at such time and to
the extent permitted by all Legal Requirements, Borrower shall pay an amount
equal to the difference between (a) the lesser of the amount of interest which
would have accrued if such designated rates had at all times been in effect and
the amount of interest which would have accrued if the Maximum Rate had at all
times been in effect, and (b) the amount of interest actually paid or accrued on
the Total Principal Debt.

         3.7 INTEREST CALCULATIONS.

         (a) All payments of interest shall be calculated on the basis of actual
number of days (including the first (1st) day but excluding the last day)
elapsed but computed as if each calendar year consisted of 360 days in the case
of a Eurodollar Borrowing, Prime Rate Borrowing, or Swing Line Borrowing. All
interest rate determinations and calculations by Administrative Agent shall be
conclusive and binding absent manifest error.

         (b) The provisions of this Agreement relating to the calculation of the
Prime Rate and the Adjusted Eurodollar Rate are included only for the purpose of
determining the rate of interest or other amounts to be paid hereunder that are
based upon such rate.

         3.8 MAXIMUM RATE. Regardless of any provision contained in any Loan
Document, no Credit Party shall ever be entitled to contract for, charge, take,
reserve, receive, or apply, as interest on the Obligation, or any part thereof,
any amount in excess of the Maximum Rate, and if any Credit Party ever does so,
then such excess shall be deemed a partial prepayment of principal and treated
hereunder as such and any remaining excess shall be refunded to Borrower. In
determining if the interest paid or payable exceeds the Maximum Rate, Borrower
and the Credit Parties shall, to the maximum extent permitted under all Legal
Requirements, (a) treat all Borrowings as but a single extension of credit (and
the Credit Parties and Borrower agree that such is the case and that provision
herein for multiple Borrowings is for convenience only), (b) characterize any
non-principal payment as an expense, fee, or premium rather than as interest,
(c) exclude voluntary prepayments and the effects thereof, and (d) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the Obligation; provided that if the Obligation is paid and
performed in full prior to the end of the full contemplated term thereof, and if

                                       22
<PAGE>   29

the interest received for the actual period of existence thereof exceeds the
Maximum Amount, then the Credit Parties shall refund such excess, and, in such
event, the Credit Parties shall not, to the extent permitted by all Legal
Requirements, be subject to any penalties provided by any Legal Requirements for
contracting for, charging, taking, reserving, or receiving interest in excess of
the Maximum Amount.

         3.9 INTEREST PERIODS. When Borrower requests any Eurodollar Borrowing,
Borrower may elect the interest period (each an "INTEREST PERIOD") applicable
thereto, which shall be, at Borrower's option, one (1) month or two (2), three
(3), or six (6) months, in each case to the extent available from each Lender;
provided, however, that: (a) the initial Interest Period for a Eurodollar
Borrowing shall commence on the date of such Borrowing (including the date of
any Conversion thereto), and each Interest Period occurring thereafter in
respect of such Borrowing shall commence on the day on which the next preceding
Interest Period applicable thereto expires; (b) if any Interest Period for a
Eurodollar Borrowing begins on a day for which there is no numerically
corresponding Business Day in the calendar month at the end of such Interest
Period, then such Interest Period shall end on the next Business Day immediately
following what otherwise would have been such numerically corresponding day in
the calendar month at the end of such Interest Period (unless such date would be
in a different calendar month from what would have been the month at the end of
such Interest Period, or unless there is no numerically corresponding day in the
calendar month at the end of the Interest Period; whereupon, such Interest
Period shall end on the last Business Day in the calendar month at the end of
such Interest Period); (c) no Interest Period may be chosen with respect to any
portion of the Total Principal Debt which would extend beyond the scheduled
repayment date (including any dates on which mandatory prepayments are required
to be made) for such portion of the Total Principal Debt; and (d) no more than
an aggregate of five (5) Interest Periods shall be in effect at one time.

         3.10 CONVERSIONS; CONTINUATIONS. Borrower may (a) Convert a Eurodollar
Borrowing on the last day of an Interest Period to a Prime Rate Borrowing, (b)
Convert a Prime Rate Borrowing at any time to a Eurodollar Borrowing, and (c)
elect to Continue a Borrowing by selecting a new Interest Period (in the case of
a Eurodollar Borrowing), by giving a Notice of Conversion/Continuation to
Administrative Agent no later than 9:00 a.m. on the third (3rd) Business Day
prior to the date of Conversion or the last day of the Interest Period, as the
case may be (in the case of a Conversion to a Eurodollar Borrowing or a
Continuation and election of a new Interest Period), and no later than 9:00 a.m.
one (1) Business Day prior to the last day of the Interest Period (in the case
of a Conversion to a Prime Rate Borrowing); provided that, the principal amount
Converted to, or Continued as, a Eurodollar Borrowing shall be in a minimum
amount of $5,000,000 or a greater integral multiple of $1,000,000.
Administrative Agent shall timely notify each Lender with respect to each Notice
of Conversion/Continuation. Absent Borrower's Notice of Conversion/Continuation,
a Eurodollar Borrowing shall be deemed Converted to a Prime Rate Borrowing
effective as of the expiration of the Interest Period applicable thereto. No
Eurodollar Borrowing may be either made or Continued as a Eurodollar Borrowing,
and no Prime Rate Borrowing may be Converted to a Eurodollar Borrowing, (i) if
the interest rate for such Eurodollar Borrowing would exceed the Maximum Rate,
or (ii) while an Event of Default exists, unless Required Lenders otherwise
consent in writing.

         3.11 ORDER OF APPLICATION.

         (a) Payments and prepayments of the Obligation shall be applied in the
order and manner specified in this Agreement; provided, however, if no order is
otherwise specified and no Potential Default or Event of Default exists,
payments and prepayments of the Obligation shall be applied first, to fees,
second, to accrued interest then due and payable on the Total Principal Debt,
and then to the remaining Obligation in the order and manner as Borrower may
direct.

                                       23
<PAGE>   30

         (b) If a Potential Default or Event of Default exists (or if Borrower
fails to give directions as permitted under SECTION 3.11(a)), any payment or
prepayment (including proceeds from the exercise of any Rights) shall be applied
to the Obligation in the following order: (i) to the ratable payment of all
fees, expenses, and indemnities for which the Credit Parties have not been paid
or reimbursed in accordance with the Loan Documents; (ii) to the ratable payment
of accrued and unpaid interest on the Swing Line Principal Debt; (iii) to the
ratable payment of accrued and unpaid interest on the Total Principal Debt; (iv)
to the ratable payment of any reimbursement obligation with respect to the Swing
Line Principal Debt which is due and payable and which remains unfunded by any
Borrowing under this Agreement; provided that, such payments shall be allocated
among the Lenders which have funded their participation in the Swing Line
Principal Debt; (v) to the ratable payment of the Total Principal Debt; and (vi)
to the payment of the remaining Obligation in the order and manner Required
Lenders deem appropriate.

         (c) Subject to the provisions of SECTION 12 and provided that
Administrative Agent shall not in any event be bound to inquire into or to
determine the validity, scope, or priority of any interest or entitlement of any
Credit Party and may suspend all payments or seek appropriate relief (including
instructions from Required Lenders or an action in the nature of interpleader)
in the event of any doubt or dispute as to any apportionment or distribution
contemplated hereby, Administrative Agent shall promptly distribute such amounts
to each Credit Party in accordance with this Agreement and the related Loan
Documents.

         3.12 RIGHT OF SET-OFF; ADJUSTMENTS.

         (a) SET-OFF. Upon the occurrence and during the continuance of any
Event of Default, each Lender (and each of its Affiliates) is hereby authorized
at any time and from time to time, to the fullest extent permitted by applicable
Legal Requirements, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender (or any of its Affiliates) to or
for the credit or the account of Borrower against any and all of the obligations
of Borrower now or hereafter existing under this Agreement and the Note held by
such Lender, irrespective of whether such Lender shall have made any demand
under this Agreement or such Note and although such obligations may be
unmatured. Each Lender agrees promptly to notify Borrower 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. The
rights of each Lender under this SECTION 3.12(a) are in addition to other rights
and remedies (including, without limitation, other rights of set- off) that such
Lender may have.

         (b) SHARING OF PAYMENTS. If any Lender (a "BENEFITTED LENDER") shall at
any time receive any payment of all or part of the Borrowings owing to it, or
interest thereon, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion
than any such payment to or collateral received by any other Lender, if any, in
respect of such other Lender's Borrowings owing to it, or interest thereon
(other than mandatory payments due in connection with the Tranche B Termination
Date or payments to the Tranche B Lenders in connection with the admission of a
Subsequent Lender or an Increasing Lender), then such Benefitted Lender shall
purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Borrowings owing to it, or shall provide
such other Lenders with the benefits of any such collateral, or the proceeds
thereof, as shall be necessary to cause such Benefitted Lender to share the
excess payment or benefits of such collateral or proceeds ratably with all
Lenders; provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such Benefitted Lender, then such purchase
shall be rescinded, and the purchase price and

                                       24
<PAGE>   31

benefits returned, to the extent of such recovery, but without interest.
Borrower agrees that any Lender so purchasing a participation from a Lender
pursuant to this SECTION 3.12(b) may, to the fullest extent permitted by
applicable Legal Requirements, exercise all of its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Person were the direct creditor of Borrower in the amount of such participation.

         3.13 BOOKING BORROWINGS. To the extent permitted by all Legal
Requirements, any Lender may make, carry, or transfer its Borrowings at, to, or
for the account of any of its branch offices or the office of any of its
Affiliates; provided that no Affiliate shall be entitled to receive any greater
payment under SECTION 4 than the transferor Lender would have been entitled to
receive with respect to such Borrowings.

SECTION 4 CHANGE IN CIRCUMSTANCES.

         4.1 INCREASED COST AND REDUCED RETURN.

         (a) CHANGE IN LEGAL REQUIREMENTS. If, after the date hereof, the
adoption of any applicable Legal Requirement, or any change in any applicable
Legal Requirement, or any change in the interpretation or administration thereof
by any Governmental Authority charged with the interpretation or administration
thereof, or compliance by any Lender (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
Governmental Authority:

                  (i) shall subject such Lender (or its Applicable Lending
         Office) to any tax, duty, or other charge with respect to any
         Eurodollar Borrowing, its Notes, or its obligation to make Eurodollar
         Borrowings, or change the basis of taxation of any amounts payable to
         such Lender (or its Applicable Lending Office) under this Agreement or
         its Notes in respect of any Eurodollar Borrowings (other than taxes
         imposed on the overall net income of such Lender by the jurisdiction in
         which such Lender has its principal office or such Applicable Lending
         Office);

                  (ii) shall impose, modify, or deem applicable any reserve,
         special deposit, assessment, or similar requirement (other than the
         Reserve Requirement utilized in the determination of the Adjusted
         Eurodollar Rate) relating to any extensions of credit or other assets
         of, or any deposits with or other liabilities or commitments of, such
         Lender (or its Applicable Lending Office), including the Commitment of
         such Lender hereunder; or

                  (iii) shall impose on such Lender (or its Applicable Lending
         Office) or the London interbank market any other condition affecting
         this Agreement or its Notes or any of such extensions of credit or
         liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Borrowings or to reduce any sum received or
receivable by such Lender (or its Applicable Lending Office) under this
Agreement or its Note with respect to any Eurodollar Borrowings, then Borrower
shall pay to such Lender on demand such amount or amounts as will compensate
such Lender for such increased cost or reduction. If any Lender requests
compensation by Borrower under this SECTION 4.1(a), then Borrower may, by notice
to such Lender (with a copy to Administrative Agent), suspend the obligation of
such Lender to make or Continue Eurodollar Borrowings, or Convert all Eurodollar
Borrowings into Prime Rate Borrowings, until the event or condition giving rise
to such request ceases to be in effect (in which case the provisions of SECTION
4.4 shall be

                                       25
<PAGE>   32

applicable); provided that such suspension shall not affect the Right of such
Lender to receive the compensation so requested.

         (b) CAPITAL ADEQUACY. If, after the date hereof, any Lender shall have
determined that the adoption of any applicable Legal Requirement regarding
capital adequacy or any change therein or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such
Governmental Authority, has or would have the effect of reducing the rate of
return on the capital of such Lender or any corporation controlling such Lender
as a consequence of such Lender's obligations hereunder to a level below that
which such Lender or such corporation could have achieved but for such adoption,
change, request, or directive (taking into consideration its policies with
respect to capital adequacy), then from time to time upon demand Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender for such reduction.

         (c) NOTICE. Each Lender shall promptly notify Borrower and
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Lender to compensation pursuant to this
SECTION 4.1 and will use reasonable efforts to designate a different Applicable
Lending Office if such designation will avoid the need for, or reduce the amount
of, such compensation and will not, in the judgment of such Lender, be otherwise
disadvantageous to it. Any Lender claiming compensation under this SECTION 4.1
shall furnish to Borrower and Administrative Agent a statement setting forth the
additional amount or amounts to be paid to it hereunder which shall be
conclusive in the absence of manifest error. In determining such amount, such
Lender may use any reasonable averaging and attribution methods.

         4.2 LIMITATION ON TYPES OF BORROWINGS. If on or prior to the first
(1st) day of any Interest Period for any Eurodollar Borrowing:

         (a) Administrative Agent determines (which determination shall be
conclusive) that by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
for such Interest Period; or

         (b) Required Lenders determine (which determination shall be
conclusive) and notify Administrative Agent that the Adjusted Eurodollar Rate
will not adequately and fairly reflect the cost to Lenders of funding Eurodollar
Borrowings for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof specifying
the relevant amounts or periods, and so long as such condition remains in
effect, Lenders shall be under no obligation to make additional Eurodollar
Borrowings, Continue any Eurodollar Borrowings, or to Convert any Prime Rate
Borrowings to Eurodollar Borrowings and Borrower shall, on the last day(s) of
the then-current Interest Period(s) for the outstanding Eurodollar Borrowings,
either prepay such Borrowings or Convert such Borrowings into Prime Rate
Borrowings in accordance with the terms of this Agreement.

         4.3 ILLEGALITY. Notwithstanding any other provision of this Agreement,
in the event that it becomes unlawful for any Lender or its Applicable Lending
Office to make, maintain, or fund Eurodollar Borrowings hereunder, then such
Lender shall promptly notify Administrative Agent and Borrower thereof and such
Lender's obligation to make or Continue Eurodollar Borrowings and to Convert
Prime Rate Borrowings into Eurodollar Borrowings shall be suspended until such
time as such Lender may again make, maintain, and fund Eurodollar Borrowings (in
which case the provisions of SECTION 4.4 shall be applicable).

                                       26
<PAGE>   33

         4.4 TREATMENT OF AFFECTED LOANS. If the obligation of any Lender to
make or Continue Eurodollar Borrowings or to Convert Prime Rate Borrowings into
Eurodollar Borrowings shall be suspended pursuant to SECTION 4.1, 4.2, or 4.3,
then such Lender's Eurodollar Borrowings shall be automatically Converted into
Prime Rate Borrowings on the last day(s) of the then current Interest Period(s)
for all Eurodollar Borrowings (or, in the case of a Conversion required by
SECTION 4.3, on such earlier date as such Lender may specify to Borrower with a
copy to Administrative Agent) and, unless and until such Lender gives notice as
provided below that the circumstances specified in SECTION 4.1, 4.2, or 4.3 that
gave rise to such Conversion no longer exist:

         (a) to the extent that such Lender's Eurodollar Borrowings have been so
Converted, all payments and prepayments of principal that would otherwise be
applied to such Lender's Eurodollar Borrowings shall be applied instead to its
Prime Rate Borrowings; and

         (b) all Borrowings that would otherwise be made or Continued by such
Lender as Eurodollar Borrowings shall be made or Continued instead as Prime Rate
Borrowings, and all Borrowings of such Lender that would otherwise be Converted
into Eurodollar Borrowings shall be Converted instead into (or shall remain as)
Prime Rate Borrowings.

If such Lender gives notice to Borrower (with a copy to Administrative Agent)
that the circumstances specified in SECTION 4.1, 4.2, or 4.3 that gave rise to
the Conversion of such Lender's Eurodollar Borrowings pursuant to this SECTION
4.4 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Borrowings made by
other Lenders are outstanding, then such Lender's Prime Rate Borrowings shall be
automatically Converted, on the first (1st) day(s) of the next succeeding
Interest Period(s) for such outstanding Eurodollar Borrowings, to the extent
necessary so that, after giving effect thereto, all Eurodollar Borrowings held
by Lenders are held Pro Rata (as to principal amounts, Types, and Interest
Periods).

         4.5 COMPENSATION. Upon the request of any Lender, Borrower shall pay to
such Lender such amount or amounts as shall be sufficient (in the reasonable
opinion of such Lender) to compensate it for any loss, cost, or expense (herein
called a "CONSEQUENTIAL LOSS") incurred by it as a result of:

         (a) any payment, prepayment, or Conversion of a Eurodollar Borrowing
for any reason (including the acceleration of the Obligation pursuant to SECTION
11.1) on a date other than the last day of the Interest Period for such
Borrowing; or

         (b) any failure by Borrower for any reason (including the failure of
any condition precedent specified in SECTION 6 to be satisfied) to borrow,
Convert, Continue, or prepay a Eurodollar Borrowing on the date for such
Borrowing, Conversion, Continuation, or prepayment specified in the relevant
Notice of Borrowing, Notice of Conversion/Continuation, or Notice of Prepayment.

         4.6 TAXES.

         (a) Any and all payments by Borrower to or for the account of any
Credit Party hereunder or under any other Loan Document shall be made free and
clear of and without deduction for any and all present or future Taxes,
excluding, in the case of each Credit Party, Taxes based on or measured by its
income, and franchise taxes imposed on it by the jurisdiction under the Legal
Requirements of which such Credit Party (or its Applicable Lending Office) is
organized or any political subdivision thereof (such income and

                                       27
<PAGE>   34

franchise Taxes being "EXCLUDED TAXES"). If Borrower shall be required by any
Legal Requirement to deduct any Taxes (other than Excluded Taxes) from or in
respect of any sum payable under this Agreement or any other Loan Document to
any Credit Party, then (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this SECTION 4.6) such Credit Party receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) Borrower shall make such deductions, and (iii) Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with all Legal Requirements.

         (b) In addition, Borrower agrees to pay any and all present or future
stamp or documentary Taxes and any other excise or property Taxes or charges or
similar levies which arise from any payment made under this Agreement or any
other Loan Document or from the execution or delivery of, or otherwise with
respect to, this Agreement or any other Loan Document (hereinafter referred to
as "OTHER TAXES").

         (c) Borrower agrees to indemnify each Credit Party for the full amount
of Taxes (other than Excluded Taxes) and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this SECTION 4.6) paid by such Credit Party on behalf of any Company (as the
case may be) and any liability (including penalties, interest, and expenses)
arising therefrom or with respect thereto.

         (d) Each Lender organized under the Legal Requirements of a
jurisdiction outside the United States, on or prior to the date of its execution
and delivery of this Agreement in the case of each Lender listed on the
signature pages hereof and on or prior to the date on which it becomes a Lender
in the case of each other Lender, and from time to time thereafter if requested
in writing by Borrower or Administrative Agent (but only so long as such Lender
remains lawfully able to do so), shall provide Borrower and Administrative Agent
with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Lender is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States, (ii) Internal Revenue Service Form W-8 or W-9, as appropriate, or any
successor form prescribed by the Internal Revenue Service, and (iii) any other
form or certificate required by any taxing authority (including any certificate
required by Sections 871(h) and 881(c) of the Tax Code), certifying that such
Lender is entitled to an exemption from or a reduced rate of tax on payments
pursuant to this Agreement or any of the other Loan Documents.

         (e) For any period with respect to which a Lender has failed to provide
Borrower and Administrative Agent with the appropriate form pursuant to SECTION
4.6(d) (unless such failure is due to a change in any Legal Requirement
occurring subsequent to the date on which a form originally was required to be
provided), such Lender shall not be entitled to indemnification under SECTIONS
4.6(a) or (b) with respect to Taxes imposed by the United States; provided,
however, that should a Lender, which is otherwise exempt from or subject to a
reduced rate of withholding tax, become subject to Taxes (other than Excluded
Taxes) because of its failure to deliver a form required hereunder, Borrower
shall take such steps as such Lender shall reasonably request to assist such
Lender to recover such Taxes.

         (f) If Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this SECTION 4.6, then such Lender will agree
to use reasonable efforts to change the jurisdiction of its Applicable Lending
Office so as to eliminate or reduce any such additional payment which may

                                       28
<PAGE>   35

thereafter accrue if such change, in the judgment of such Lender, is not
otherwise disadvantageous to such Lender.

         (g) Within thirty (30) days after the date of any payment of Taxes or
Other Taxes, Borrower shall furnish to Administrative Agent the original or a
certified copy of a receipt evidencing such payment.

         (h) Without prejudice to the survival of any other agreement of
Borrower hereunder, the agreements and obligations of Borrower contained in
SECTIONS 4.1, 4.5 and 4.6 shall survive the termination of the Total Commitment
and the payment in full of the Notes.

         (b) OPINION OF COUNSEL FOR BORROWER. The Credit Parties and their
respective counsel shall have received originally executed copies of a favorable
written opinion of counsel for Borrower, in form and substance reasonably

         (d) COMPLETION OF PROCEEDINGS. All corporate and other proceedings
taken or to be taken in connection with the transactions contemplated hereby and
all documents incidental thereto not previously found acceptable by

                                       30
<PAGE>   37

         (a) NOTICE OF BORROWING. Administrative Agent shall have received, in
accordance with the provisions of SECTION 2.2, SECTION 2.5 and SECTION 3.10, an
originally executed Notice of Borrowing or Notice of Conversion/Continuation, as
applicable.

         (b) REPRESENTATIONS AND WARRANTIES; PERFORMANCE OF AGREEMENTS. As of
the date of such Credit Extension, Borrower's representations and warranties in
each Loan Document are true, correct, and complete in all material respects
(unless they speak to a specific date or are based on facts which have changed
by transactions expressly contemplated or permitted by this Agreement).

         (c) NO DEFAULT. No Potential Default or Event of Default exists or
would be caused by the making of such Credit Extension.

         (d) NO INJUNCTION OR RESTRAINING ORDER. No order, judgment, or decree
of any Governmental Authority shall purport to enjoin or restrain any Credit
Party from making such Credit Extension.

         (e) NO VIOLATION. The making of such Credit Extension shall not violate
any Legal Requirement, including Regulation T, Regulation U, or Regulation X of
the Board of Governors of the Federal Reserve System.

         (f) OTHER MATTERS. All matters related to such Credit Extension must be
satisfactory to Required Lenders and their respective counsel in their
reasonable determination, and upon the reasonable request of Administrative
Agent, Borrower shall deliver to Administrative Agent evidence substantiating
any of the matters in the Loan Documents which are necessary to enable Borrower
to qualify for such Credit Extension.

Each condition precedent in this Agreement is material to the transactions
contemplated in this Agreement, and time is of the essence in respect of each
thereof. Subject to the prior approval of Required Lenders, the Credit Parties
may make a Credit Extension without all conditions being satisfied, but, to the
extent permitted by all Legal Requirements, such Credit Extension shall not be
deemed to be a waiver of the requirement that each such condition precedent be
satisfied as a prerequisite for any subsequent Credit Extension, unless Required
Lenders specifically waive each such item in writing.

         SECTION 7 REPRESENTATIONS AND WARRANTIES. Borrower represents and
warrants to the Credit Parties as follows:

         7.1 PURPOSE OF CREDIT FACILITY. Borrower will use (or will loan or
contribute such proceeds to its Subsidiaries to so use) all proceeds of Credit
Extensions for one or more of the following: (a) to refinance existing Debt of
the Companies including, but not limited to the Existing Credit Facilities; and
(b) for lawful, corporate purposes including, without limitation, liquidity
support for commercial paper. No Restricted Company is engaged principally, or
as one of its important activities, in the business of extending credit for the
purpose of purchasing or carrying any "margin stock" within the meaning of
Regulation U. No part of the proceeds of any Credit Extension will be used,
directly or indirectly, for a purpose which violates any Legal Requirement,
including the provisions of Regulation T, U, or X (as enacted by the Board of
Governors of the Federal Reserve System, as amended). "Margin Stock" (as defined
in Regulation U) constitutes less than twenty-five percent (25%) of those assets
of the Companies that are subject to any limitation on sale, pledge, or similar
restrictions hereunder.

                                       31
<PAGE>   38

         7.2 EXISTENCE, GOOD STANDING, AUTHORITY, AND AUTHORIZATIONS. Each
Restricted Company is duly organized, validly existing, and in good standing
under the Legal Requirements of its jurisdiction of organization. Each
Restricted Company is duly qualified to transact business and is in good
standing in each jurisdiction where the nature and extent of its business and
properties require the same, except where the failure to be so qualified could
not constitute a Material Adverse Event. Each Restricted Company possesses all
the Authorizations necessary or required in the conduct of its respective
business(es), and the same are valid, binding, enforceable, and subsisting
without any defaults thereunder or enforceable adverse limitations thereon and
are not subject to any proceedings or claims opposing the issuance, development,
or use thereof or contesting the validity thereof, except for any such
circumstance that could not be a Material Adverse Event.

         7.3 SUBSIDIARIES; CAPITAL STOCK. The Companies have no Subsidiaries
except as disclosed on SCHEDULE 7.3, such schedule reflecting each Subsidiary's
jurisdiction of incorporation (as supplemented and modified in writing from time
to time to reflect any changes to such SCHEDULE as a result of transactions
permitted by the Loan Documents) and each Unrestricted Subsidiary is designated
as such. All of the outstanding Stock of each Subsidiary is duly authorized,
validly issued, fully paid, and nonassessable and, except (a) for directors'
qualifying shares, or (b) as otherwise set forth on SCHEDULE 7.3, are owned
directly or indirectly by Borrower (as supplemented and modified in writing from
time to time to reflect any changes to such SCHEDULE as a result of transactions
permitted by the Loan Documents), free and clear of any Liens, restrictions,
claims, or Rights of another Person, and none of such Stock owned by any Company
is subject to any restriction on transfer thereof except for restrictions
imposed by securities Legal Requirements and general corporate Legal
Requirements.

         7.4 AUTHORIZATION AND CONTRAVENTION. The execution and delivery by
Borrower of each Loan Document and the performance by Borrower of its
obligations thereunder (a) are within the corporate power of Borrower, (b) have
been duly authorized by all necessary corporate action on the part of Borrower,
(c) require no action by or in respect of Authorizations of or filing with, any
Governmental Authority, which action, Authorization, or filing has not been
taken, received, or made on or prior to the Closing Date (or if later, the date
of execution and delivery of such Loan Document) other than filing of the Loan
Documents pursuant to securities Legal Requirements, (d) will not violate any
provision of the Constituent Documents of any Company, (e) will not violate any
provision of any Legal Requirement applicable to any Company, other than such
violations which individually or collectively could not be a Material Adverse
Event, (f) will not violate any material written or oral agreements, contracts,
commitments, or understandings to which any Company is a party, other than such
violations which could not be a Material Adverse Event, or (g) will not result
in the creation or imposition of any Lien on any asset of any Company.

         7.5 BINDING EFFECT. Upon execution and delivery by all parties thereto,
each Loan Document to which Borrower is a party will constitute a legal, valid,
and binding obligation of Borrower, enforceable against Borrower in accordance
with its terms, except as enforceability may be limited by applicable Debtor
Relief Laws and general principles of equity.

         7.6 FINANCIAL STATEMENTS. The Current Financials were prepared in
accordance with GAAP and present fairly, in all material respects, the
consolidated financial condition, results of operations, and cash flows of the
Companies as of and for the portion of the fiscal year ending on the date or
dates thereof (subject only to normal year-end audit adjustments). There were no
material liabilities, direct or indirect, fixed or contingent, of the Companies
as of the date or dates of the Current Financials which are required under GAAP
to be reflected therein or in the notes thereto, and are not so reflected.
Except for transactions

                                       32
<PAGE>   39

directly related to, or specifically contemplated by, the Loan Documents, there
have been no changes in the consolidated financial condition of the Companies
from that shown in the Current Financials after such date which could be a
Material Adverse Event, nor has any Company incurred any liability (including
any liability under any Environmental Law), direct or indirect, fixed or
contingent, after such date which could be a Material Adverse Event.

         7.7 LITIGATION, CLAIMS, INVESTIGATIONS. No Company is subject to, or
aware of the threat of, any Litigation which is reasonably likely to be
determined adversely to any Company, and, if so adversely determined, could
(individually or collectively with other Litigation) be a Material Adverse
Event. There are no outstanding orders or judgments for the payment of money in
excess of $10,000,000 (individually or collectively) or any warrant of
attachment, sequestration, or similar proceeding against the assets of any
Company having a value (individually or collectively) of $ 10,000,000 or more
which is not either (a) stayed on appeal, or (b) being contested in good faith
by appropriate proceedings diligently conducted, and against which reserves or
other provisions required by GAAP have been made. There are no formal
complaints, suits, claims, investigations, or proceedings initiated at or by any
Governmental Authority pending or, to the best knowledge of Borrower, threatened
by or against any Company which could be a Material Adverse Event, nor any
judgments, decrees, or orders of any Governmental Authority outstanding against
any Company that could be a Material Adverse Event.

         7.8 TAXES. All Tax returns of each Company required to be filed have
been filed (or extensions have been granted) prior to delinquency, except for
any such returns for which the failure to so file could not be a Material
Adverse Event, and all Taxes imposed upon each Company which are due and payable
have been paid prior to delinquency, other than Taxes (a) that are being
contested in good faith by appropriate proceedings diligently conducted, and
against which reserves or other provisions required by GAAP have been made, or
(b) for which nonpayment thereof could not be a Material Adverse Event.

         7.9 ENVIRONMENTAL MATTERS. No Company, after reasonable inquiry, (a)
knows of any environmental condition or circumstance, such as the presence or
Release of any Hazardous Materials, on any property presently or previously
owned or leased by any Company or to which Hazardous Materials generated by any
Company have been taken, that could be a Material Adverse Event, (b) knows of
any violation by any Company of any Environmental Law that could be a Material
Adverse Event, or (c) knows that any Company is under any obligation to remedy
any violation of any Environmental Law or any Release or threatened Release of
any Hazardous Materials that could be a Material Adverse Event.

         7.10 EMPLOYEE BENEFIT PLANS. (a) No Employee Plan has incurred an
accumulated funding deficiency, as defined in Section 302 of ERISA and Section
412 of the Tax Code, (b) neither Borrower nor any ERISA Affiliate has incurred
material liability which is currently due and remains unpaid under Title IV of
ERISA to the PBGC or to an Employee Plan in connection with any such Employee
Plan, (c) neither Borrower nor any ERISA Affiliate has withdrawn in whole or in
part from participation in a Multiemployer Plan, (d) Borrower has not engaged in
any "prohibited transaction" (as defined in Section 406 of ERISA or Section 4975
of the Tax Code) which could be a Material Adverse Event, and (e) no Reportable
Event has occurred which is likely to result in the termination of an Employee
Plan. The present value of all benefit liabilities within the meaning of Title
IV of ERISA under each Employee Plan (based on those actuarial assumptions used
to fund such Employee Plan) did not, as of the last annual valuation date for
the most recent plan year of such Employee Plan, exceed the value of the assets
of such Employee Plan, and the total present values of all benefit liabilities
within the meaning of Title IV of ERISA of all Employee Plans (based on the
actuarial assumptions used to fund each such Employee Plan) did not, as of the
respective annual

                                       33
<PAGE>   40

valuation dates for the most recent plan year of each such Plan, exceed the
value of the assets of all such Employee Plans.

         7.11 PROPERTIES; LIENS. Each Restricted Company has good and
indefeasible title to all its property reflected on the Current Financials,
except for property that (a) is obsolete, or (b) has been disposed of in the
ordinary course of business or as otherwise permitted by the Loan Documents.
Except for Permitted Liens, there is no Lien on any property of any Restricted
Company.

         7.12 GOVERNMENT REGULATIONS. No Company is subject to regulation under
the Investment Company Act of 1940, as amended, the Public Utility Holding
Company Act of 1935, as amended, or any other Legal Requirement (other than
Regulations T, U, and X of the Board of Governors of the Federal Reserve System)
which regulates the incurrence of Debt.

         7.13 TRANSACTIONS WITH AFFILIATES. No Restricted Company is a party to
a transaction with any of its Affiliates, other than transactions in the
ordinary course of business and upon fair and reasonable terms not materially
less favorable than such Restricted Company could obtain or could become
entitled to in an arm's-length transaction with a Person that was not its
Affiliate.

         7.14 NO DEFAULT. No event has occurred and is continuing or would
result from the incurring of obligations by Borrower under this Agreement or any
other Loan Document which constitutes an Event of Default or a Potential
Default. No Restricted Company is in default under or with respect to any
material written or oral agreements, contracts, commitments, or understandings
to which any Restricted Company is party which could, individually or together
with all such defaults, be a Material Adverse Event.

         7.15 SOLVENCY. At the time of each Credit Extension hereunder, each
Restricted Company is (and after giving effect to the transactions contemplated
by the Loan Documents and any incurrence of additional Debt, will be) Solvent.

         7.16 COMPLIANCE WITH LEGAL REQUIREMENTS. No Company is in violation of
any Legal Requirements (including Environmental Laws), other than such
violations which could not, individually or collectively, be a Material Adverse
Event. No Company has received notice alleging any non-compliance with any Legal
Requirements, except for such non-compliance which no longer exists or which
could not be a Material Adverse Event.

         7.17 FULL DISCLOSURE. There is no material fact or condition relating
to the Loan Documents or the financial condition, business, or property of any
Company which could be a Material Adverse Event and which has not been
disclosed, in writing, to Administrative Agent. All information heretofore
furnished by any Company to any Credit Party in connection with the Loan
Documents was, and all such information hereafter furnished by any Company to
any Credit Party will be, true and accurate in all material respects or based on
reasonable estimates on the date as of which such information is stated or
certified.

         7.18 SENIOR DEBT. The Obligation constitutes (and will constitute until
payment in full and cancellation of all Commitments hereunder) Borrower's direct
and unconditional obligation and ranks at least pari passu with other unsecured
and unsubordinated Debt of Borrower.

SECTION 8 AFFIRMATIVE COVENANTS. Borrower covenants and agrees to perform,
observe, and comply with each of the following covenants, from the Closing Date
and so long thereafter as Lenders are

                                       34
<PAGE>   41

committed to make any Credit Extensions under this Agreement and thereafter
until the payment in full of all Principal Debt and payment in full of all other
interest, fees, and other amounts of the Obligation then due and owing, unless
Borrower receives a prior written consent to the contrary by Administrative
Agent as authorized by Required Lenders:

Extensions only for the purposes represented herein.

         Companies;

specifying the nature thereof and what action Borrower or any other Company has
taken, is taking, or proposes to take with respect thereto; provided, however,

be in full force and effect in any material respect or be declared to be null
and void (other than in accordance with the terms hereof or thereof) or the
validity or enforceability thereof be contested by Borrower or Borrower shall
deny in writing that it has any or any further liability or obligations under
any Loan Document to which it is a party.

SECTION 11 RIGHTS AND REMEDIES.

         11.1 REMEDIES UPON DEFAULT.

         (a) If an Event of Default exists under SECTION 10.3(c) or 10.3(d),
then the commitment to extend credit hereunder shall automatically terminate and
the entire unpaid balance of the Obligation shall automatically become due and
payable without any action or notice of any kind whatsoever.

         (b) If any Event of Default exists, then Administrative Agent may (and,
subject to the terms of SECTION 12, shall upon the request of Required Lenders)
or Required Lenders may, do any one or more of the following: (i) if the
maturity of the Obligation has not already been accelerated under SECTION
11.1(a), then declare the entire unpaid balance of the Obligation, or any part
thereof, immediately due and payable, whereupon it shall be due and payable;
(ii) terminate the commitments of Lenders to extend credit hereunder; (iii)
reduce any claim to judgment; (iv) to the extent permitted by all Legal
Requirements, exercise (or request each Lender to, and each Lender shall be
entitled to, exercise) the Rights of offset or banker's Lien against the
interest of any Company in and to every account and other property of any
Company which are in the possession of any Credit Party to the extent of the
full amount of the Obligation (to the extent permitted by all Legal
Requirements, Borrower being deemed directly obligated to each Credit Party in
the full amount of the Obligation for such purposes); and (v) exercise any and
all other legal or equitable Rights afforded by the Loan Documents, the Legal
Requirements of the State of Texas, or any other applicable jurisdiction as
Administrative Agent shall deem appropriate, or otherwise, including, but not
limited to, the Right to bring suit or other proceedings before any Governmental
Authority either for specific performance of any covenant or condition contained
in any of the Loan Documents or in aid of the exercise of any Right granted to
any Credit Party in any of the Loan Documents.

         11.2 BORROWER WAIVERS. To the extent permitted by all Legal
Requirements, Borrower hereby waives presentment and demand for payment,
protest, notice of intention to accelerate, notice of acceleration, and notice
of protest and nonpayment, and agrees that its liability with respect to the
Obligation (or any part thereof) shall not be affected by any renewal or
extension in the time of payment of the Obligation (or any part thereof), by any
indulgence, or by any release or change in any security for the payment of the
Obligation (or any part thereof).

         11.3 PERFORMANCE BY ADMINISTRATIVE AGENT. If any covenant, duty, or
agreement of Borrower is not performed in accordance with the terms of the Loan
Documents, while an Event of Default exists, then Administrative Agent may, at
its option (but subject to the approval of Required Lenders), perform or attempt
to perform such covenant, duty, or agreement on behalf of Borrower. In such
event, any amount expended by Administrative Agent in such performance or
attempted performance shall be payable by Borrower to Administrative Agent on
demand, shall become part of the Obligation, and shall bear interest

                                       44
<PAGE>   51

at the Default Rate from the date of such expenditure by Administrative Agent
until paid. Notwithstanding the foregoing, it is expressly understood that
Administrative Agent does not assume, and shall never have, except by its
express written consent, any liability or responsibility for the performance of
any covenant, duty, or agreement of Borrower.

         11.4 DELEGATION OF DUTIES AND RIGHTS. The Credit Parties may perform
any of their duties or exercise any of their Rights under the Loan Documents by
or through their respective Representatives.

         11.5 NOT IN CONTROL. Nothing in any Loan Document shall, or shall be
deemed to (a) give any Credit Party the Right to exercise control over the
assets (including real property), affairs, or management of any Company, (b)
preclude or interfere with compliance by any Company with any Legal Requirement,
or (c) require any act or omission by any Company that may be harmful to Persons
or property. Any "Material Adverse Event" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Document is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that any Credit Party acquiesces in any non-compliance by any
Company with any Legal Requirement or document, or that any Credit Party does
not expect any Company to promptly, diligently, and continuously carry out all
appropriate removal, remediation, and termination activities required or
appropriate in accordance with all Environmental Laws. The Credit Parties have
no fiduciary relationship with or fiduciary duty to any Company arising out of
or in connection with the Loan Documents, and the relationship between the
Credit Parties, on the one hand, and the Companies, on the other hand, in
connection with the Loan Documents is solely that of debtor and creditor. The
power of the Credit Parties under the Loan Documents is limited to the Rights
provided in the Loan Documents, which Rights exist solely to assure payment and
performance of the Obligation and may be exercised in a manner calculated by the
Credit Parties in their respective good faith business judgment.

         11.6 COURSE OF DEALING. The acceptance by any Credit Party at any time
and from time to time of partial payment on the Obligation shall not be deemed
to be a waiver of any Event of Default then existing. No waiver by any Credit
Party of any Event of Default shall be deemed to be a waiver of any other
then-existing or subsequent Event of Default. No delay or omission by any Credit
Party in exercising any Right under the Loan Documents shall impair such Right
or be construed as a waiver thereof or any acquiescence therein, nor shall any
single or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Documents or
otherwise.

         11.7 CUMULATIVE RIGHTS. All Rights available to the Credit Parties
under the Loan Documents are cumulative of and in addition to all other Rights
granted to the Credit Parties at law or in equity, whether or not the Obligation
is due and payable and whether or not the Credit Parties have instituted any
suit for collection, foreclosure, or other action in connection with the Loan
Documents.

         11.8 APPLICATION OF PROCEEDS. Any and all proceeds ever received by any
Credit Party from the exercise of any Rights pertaining to the Obligation shall
be applied to the Obligation in the order and manner set forth in SECTION 3.11.

         11.9 CERTAIN PROCEEDINGS. Borrower will promptly execute and deliver,
or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers any
Credit Party may reasonably request in connection with the obtaining of any
consent, approval, registration, qualification, permit, license, or
Authorization of any Governmental Authority or other Person necessary or
appropriate for the effective exercise of any Rights under the Loan Documents.

                                       45
<PAGE>   52

Because Borrower agrees that the Credit Parties' remedies at law for failure of
Borrower to comply with the provisions of this SECTION 11.9 would be inadequate
and that such failure would not be adequately compensable in damages, Borrower
agrees that the covenants of this SECTION 11.9 may be specifically enforced.

         11.10 EXPENSES; INDEMNIFICATION.

         (a) Borrower agrees to pay on demand all out-of-pocket costs and
expenses of Administrative Agent and Arranger in connection with the
syndication, preparation, execution, delivery, administration, modification, and
amendment of this Agreement, the other Loan Documents, and the other documents
to be delivered hereunder, including, without limitation, the reasonable fees
and expenses of counsel for Administrative Agent (including the cost of internal
counsel) with respect thereto and with respect to advising Administrative Agent
as to its Rights and responsibilities under the Loan Documents. Borrower further
agrees to pay on demand all costs and expenses of the Credit Parties and
Arranger, if any (including, without limitation, reasonable attorneys' fees and
expenses and the cost of internal counsel), in connection with the enforcement
(whether through negotiations, legal proceedings, or otherwise) by the Credit
Parties of the Loan Documents.

         (b) Borrower agrees to indemnify and hold harmless the Credit Parties
and Arranger and each of their respective Affiliates and their respective
officers, directors, employees, agents, and advisors (each, an "INDEMNIFIED
PARTY") from and against any and all claims, damages, losses, liabilities,
costs, and expenses (including, without limitation, reasonable attorneys' fees)
that may be incurred by or asserted or awarded against any Indemnified Party, in
each case arising out of or in connection with or by reason of (including,
without limitation, in connection with any investigation, litigation, or
proceeding or preparation of defense in connection therewith) the Loan
Documents, any of the transactions contemplated herein or the actual or proposed
use of the proceeds of the Borrowings (INCLUDING ANY OF THE FOREGOING ARISING
FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), except to the extent such claim,
damage, loss, liability, cost, or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence, bad faith, or willful misconduct. In the
case of an investigation, litigation, or other proceeding to which the indemnity
in this SECTION 11.10 applies, such indemnity shall be effective whether or not
such investigation, litigation, or proceeding is brought by any Company, its
directors, shareholders, or creditors or an Indemnified Party or any other
Person or any Indemnified Party is otherwise a party thereto and whether or not
the transactions contemplated hereby are consummated. Borrower agrees not to
assert any claim against the Indemnified Parties, on any theory of liability,
for special, indirect, consequential, or punitive damages arising out of or
otherwise relating to the Loan Documents, any of the transactions contemplated
herein or the actual or proposed use of the proceeds of any Credit Extension.

         (c) No Indemnified Party shall be liable for any error of judgment or
act done in good faith, or be otherwise liable or responsible under any
circumstances whatsoever (INCLUDING SUCH INDEMNIFIED PARTY'S NEGLIGENCE), except
to the extent found in a final, non-appealable judgment in a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence,
bad faith, or willful misconduct or resulting from such Person's breach of this
Agreement. No Indemnified Party shall have any liability with respect to, and
Borrower hereby waives, releases, and agrees not to sue any of them upon, any
claim for any special, indirect, or consequential damage suffered or incurred by
Borrower or any of its Affiliates in connection with, arising out of, or in any
way related to this Agreement or any of the other Loan Documents, or any of the
transactions contemplated by this Agreement or any of the other Loan Documents.

                                       46
<PAGE>   53

Borrower hereby waives, releases, and agrees not to sue any Indemnified Party
for exemplary or punitive damages in respect of any claim in connection with,
arising out of, or in any way related to this Agreement or any of the other Loan
Documents, or any of the transactions contemplated by this Agreement or any of
the other Loan Documents.

         (d) Without prejudice to the survival of any other agreement of
Borrower hereunder, the agreements and obligations of Borrower contained in this
SECTION 11.10 shall survive the payment in full of the Obligation and all other
amounts payable under this Agreement.

SECTION 12 AGENTS.

         12.1 APPOINTMENT, POWERS, AND IMMUNITIES. Each Lender hereby
irrevocably appoints and authorizes Administrative Agent to act as its agent
under this Agreement and the other Loan Documents with such powers and
discretion as are specifically delegated to Administrative Agent by the terms of
this Agreement and the other Loan Documents, together with such other powers as
are reasonably incidental thereto. Administrative Agent (which term as used in
this sentence and in SECTION 12.5 and the first sentence of SECTION 12.6 shall
include its Affiliates and its own and its Affiliates' officers, directors,
employees, and agents): (a) shall not have any duties or responsibilities except
those expressly set forth in this Agreement and shall not be a trustee or
fiduciary for any Lender; (b) shall not be responsible to the Lenders for any
recital, statement, representation, or warranty (whether written or oral) made
in or in connection with any Loan Document or any certificate or other document
referred to or provided for in, or received by any of them under, any Loan
Document, or for the value, validity, effectiveness, genuineness,
enforceability, or sufficiency of any Loan Document, or any other document
referred to or provided for therein or for any failure by any Company or any
other Person to perform any of its obligations thereunder; (c) shall not be
responsible for or have any duty to ascertain, inquire into, or verify the
performance or observance of any covenants or agreements by any Company or the
satisfaction of any condition or to inspect the property (including the books
and records) of any Company or any of its Affiliates; (d) shall not be required
to initiate or conduct any litigation or collection proceedings under any Loan
Document; and (e) shall not be responsible for any action taken or omitted to be
taken by it under or in connection with any Loan Document, except for its own
gross negligence or willful misconduct. Administrative Agent may employ agents
and attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care.

         12.2 RELIANCE BY ADMINISTRATIVE AGENT. Administrative Agent shall be
entitled to rely upon any certification, notice, instrument, writing, or other
communication (including, without limitation, any thereof by telephone or
telecopy) believed by it to be genuine and correct and to have been signed, sent
or made by or on behalf of the proper Person or Persons, and upon advice and
statements of legal counsel (including counsel for any Company), independent
accountants, and other experts selected by Administrative Agent. Administrative
Agent may deem and treat the payee of any Note as the holder thereof for all
purposes hereof unless and until Administrative Agent receives and accepts an
Assignment and Acceptance Agreement executed in accordance with SECTION
13.13(b). As to any matters not expressly provided for by this Agreement,
Administrative Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
Required Lenders, and such instructions shall be binding on all Lenders;
provided, however, that Administrative Agent shall not be required to take any
action that exposes Administrative Agent to personal liability or that is
contrary to any Loan Document or applicable law or

                                       47
<PAGE>   54

unless it shall first be indemnified to its satisfaction by Lenders against any
and all liability and expense which may be incurred by it by reason of taking
any such action.

         12.3 DEFAULTS. Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of a Potential Default or Event of Default
unless Administrative Agent has received written notice from a Credit Party or
Borrower specifying such Potential Default or Event of Default and stating that
such notice is a "NOTICE OF DEFAULT". In the event that Administrative Agent
receives such a notice of the occurrence of a Potential Default or Event of
Default, Administrative Agent shall give prompt notice thereof to Lenders.
Administrative Agent shall (subject to SECTION 12.2) take such action with
respect to such Potential Default or Event of Default as shall reasonably be
directed by Required Lenders, provided that, unless and until Administrative
Agent shall have received such directions, Administrative Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Potential Default or Event of Default as it shall deem advisable
in the best interest of Lenders.

         12.4 RIGHTS AS LENDER. With respect to its Commitment and the Credit
Extensions made by it, Administrative Agent (and any successor acting as
Administrative Agent) in its capacity as a Lender hereunder shall have the same
Rights and powers hereunder as any other Lender and may exercise the same as
though it were not acting as Administrative Agent, and the term "LENDER" or
"LENDERS" shall, unless the context otherwise indicates, include Administrative
Agent in its individual capacity. Administrative Agent (and any successor acting
as Administrative Agent) and its Affiliates may (without having to account
therefor to any Credit Party) accept deposits from, lend money to, make
investments in, provide services to, and generally engage in any kind of
lending, trust, or other business with any Company or any of its Affiliates as
if it were not acting as Administrative Agent, and Administrative Agent (and any
successor acting as Administrative Agent) and its Affiliates may accept fees and
other consideration from any Company or any of its Affiliates for services in
connection with this Agreement or otherwise without having to account for the
same to the Credit Parties.

         12.5 INDEMNIFICATION. Lenders agree to indemnify Administrative Agent
(to the extent not reimbursed under SECTION 11.10, but without limiting the
obligations of Borrower under such SECTION) ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including
attorneys' fees), or disbursements of any kind and nature whatsoever that may be
imposed on, incurred by or asserted against Administrative Agent (including by
any Lender) in any way relating to or arising out of any Loan Document or the
transactions contemplated thereby or any action taken or omitted by
Administrative Agent under any Loan Document (INCLUDING ANY OF THE FOREGOING
ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE AGENT); provided that no Lender
shall be liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified. Without
limitation of the foregoing, each Lender agrees to reimburse Administrative
Agent promptly upon demand for its ratable share of any costs or expenses
payable by Borrower under SECTION 11.10, to the extent that Administrative Agent
is not promptly reimbursed for such costs and expenses by Borrower. The
agreements contained in this SECTION 12.5 shall survive payment in full of the
Obligation.

         12.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender agrees that it has, independently and without reliance on Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Companies and decision
to enter into this Agreement and that it will, independently and without
reliance upon Administrative Agent or any other Lender, and based on such
documents and information as it shall deem

                                       48
<PAGE>   55

appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under the Loan Documents. Except for notices,
reports, and other documents and information expressly required to be furnished
to the Lenders by Administrative Agent hereunder, Administrative Agent shall not
have any duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition, or business of any
Company or any of its Affiliates that may come into the possession of
Administrative Agent or any of its Affiliates.

         12.7 RESIGNATION OF ADMINISTRATIVE AGENT. Administrative Agent may
resign at any time by giving notice thereof to Lenders and Borrower. Upon any
such resignation, Required Lenders shall have the right to appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by Required Lenders and shall have accepted such appointment within
thirty (30) days after the retiring Administrative Agent's giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of Lenders,
appoint a successor Administrative Agent which shall be a commercial bank
organized under the laws of the United States of America having combined capital
and surplus of at least $100,000,000. If no successor Administrative Agent has
been appointed by Required Lenders or Administrative Agent, as provided above,
then the retiring Administrative Agent's resignation shall nevertheless become
effective forty-five (45) days after the retiring Administrative Agent's notice
of resignation and Required Lenders shall thereafter perform all of the duties
of Administrative Agent hereunder and/or under any other Loan Document until
such time, if any, as Required Lenders appoint a successor Administrative Agent,
as provided in this SECTION 12.7. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor, such successor shall thereupon
succeed to and become vested with all the Rights, powers, discretion,
privileges, and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this SECTION 12 shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Administrative Agent.

         12.8 AGENTS. No Lender identified in this Agreement as "Syndication
Agent," "Documentation Agent," or "Managing Agent" shall have any rights,
powers, obligations, liabilities, responsibilities, or duties under this
Agreement other than those applicable to all Lenders as such. Without limiting
the foregoing, no Lender so identified as a "Syndication Agent," "Documentation
Agent," or "Managing Agent" shall have or be deemed to have any fiduciary
relationship with any other Credit Party.

SECTION 13 MISCELLANEOUS.

         13.1 HEADINGS. The headings, captions, and arrangements used in any of
the Loan Documents are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify, or modify the terms of the Loan
Documents, nor affect the meaning thereof.

         13.2 NONBUSINESS DAYS. In any case where any payment or action is due
under any Loan Document on a day which is not a Business Day, such payment or
action may be delayed until the next- succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; provided that if, in the case of
any such payment in respect of a Eurodollar Borrowing, the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

                                       49
<PAGE>   56

         13.3 COMMUNICATIONS. Unless specifically otherwise provided, whenever
any Loan Document requires or permits any consent, approval, notice, request, or
demand from one party to another, such communication must be in writing (which
may be by telex or telecopy) to be effective and shall be deemed to have been
given (a) if by telex, when transmitted to the telex number, if any, for such
party, and the appropriate answer back is received, (b) if by telecopy, when
transmitted to the telecopy number for such party (and all such communications
sent by telecopy shall be confirmed promptly thereafter by personal delivery or
mailing in accordance with the provisions of this SECTION 13.3; provided that
any requirement in this parenthetical shall not affect the date on which such
telecopy shall be deemed to have been delivered), (c) if by mail, on the third
(3rd) Business Day after it is enclosed in an envelope, properly addressed to
such party, properly stamped, sealed, and deposited in the appropriate official
postal service, or (d) if by any other means, when actually delivered to such
party. Until changed by notice pursuant hereto, the address (and telex and
telecopy numbers, if any) for Borrower and each Credit Party is set forth on
SCHEDULE 2.1.

         13.4 FORM AND NUMBER OF DOCUMENTS. Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Agreement must be in form and substance and in such number of counterparts as
may be reasonably satisfactory to Administrative Agent and its counsel.

         13.5 EXCEPTIONS TO COVENANTS. Borrower shall not, and shall not permit
any other Company to, take any action or fail to take any action which is
permitted as an exception to any of the covenants contained in any Loan Document
if such action or omission would result in the breach of any other covenant
contained in any of the Loan Documents.

         13.6 SURVIVAL. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Documents shall survive
all closings under the Loan Documents and, except as otherwise indicated, shall
not be affected by any investigation made by any party. All rights of, and
provisions relating to, reimbursement and indemnification of any Credit Party
shall survive termination of this Agreement and payment in full of the
Obligation.

         13.7 GOVERNING LAW. THE LEGAL REQUIREMENTS OF THE STATE OF TEXAS AND OF
THE UNITED STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES
TO THE LOAN DOCUMENTS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND
INTERPRETATION OF THE LOAN DOCUMENTS.

         13.8 INVALID PROVISIONS. If any provision in any Loan Document is held
to be illegal, invalid, or unenforceable, then such provision shall be fully
severable; the appropriate Loan Document shall be construed and enforced as if
such provision had never comprised a part thereof; and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by such
provision or by its severance therefrom. Each Credit Party and each Company
party to such Loan Document agree to negotiate, in good faith, the terms of a
replacement provision as similar to the severed provision as may be possible and
be legal, valid, and enforceable.

         13.9 ENTIRETY. THE RIGHTS AND OBLIGATIONS OF BORROWER AND THE CREDIT
PARTIES SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND
INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED
BY AND MERGED INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM
TIME TO TIME) AND THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED BY BORROWER AND/OR
ANY CREDIT PARTY (TOGETHER WITH ALL

                                       50

COMMITMENT LETTERS AND FEE LETTERS AS THEY RELATED TO THE PAYMENT OF FEES AFTER
THE CLOSING DATE)REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN
THE PARTIES.

         13.10 JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL. EACH PARTY
HERETO, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY (A)
IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL
COURTS LOCATED IN TEXAS, AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE
MADE UPON IT IN ANY LEGAL PROCEEDING ARISING OUT OF OR IN CONNECTION WITH THE
LOAN DOCUMENTS AND THE OBLIGATION BY SERVICE OF PROCESS AS PROVIDED BY TEXAS
LEGAL REQUIREMENTS, (B) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
ALL LEGAL REQUIREMENTS, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH THE LOAN
DOCUMENTS AND THE OBLIGATION BROUGHT IN ANY SUCH COURT, (C) IRREVOCABLY WAIVES
ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN

AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY HERETO ARISING OUT OF OR IN
CONNECTION WITH THE LOAN DOCUMENTS OR THE OBLIGATION SHALL BE BROUGHT IN ONE OF
THE AFOREMENTIONED COURTS, AND (G) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY ALL LEGAL REQUIREMENTS, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF
ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT OR
THE TRANSACTIONS CONTEMPLATED THEREBY. The scope of each of the foregoing
waivers is intended to be all-encompassing of any and all disputes that may be
filed in any court and that relate to the subject matter of this transaction,
including contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims. Borrower and each other party to this Agreement
acknowledge that this waiver is a material inducement to the agreement of each
party hereto to enter into a business relationship, that each has already relied
on this waiver in entering into this Agreement, and each will continue to rely
on each of such waivers in related future dealings. Borrower and each other
party to this Agreement warrant and represent that they have reviewed these
waivers with their legal counsel, and that they knowingly and voluntarily agree
to each such waiver following consultation with legal counsel. THE WAIVERS IN
THIS SECTION 13.10 ARE IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, SUPPLEMENTS, AND REPLACEMENTS TO OR OF THIS OR ANY OTHER Loan
Document. In the event of Litigation, this Agreement may be filed as a written
consent to a trial by the court.

         13.11 AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

         (a) Except as otherwise specifically provided, (i) this Agreement may
only be amended, modified or waived by an instrument in writing executed jointly
by Borrower and Required Lenders, and, in the case of any matter affecting
Administrative Agent (except removal of Administrative Agent as provided in
SECTION 12) by Administrative Agent, and may only be supplemented by documents
delivered or to be delivered in accordance with the express terms hereof, and
(ii) the other Loan Documents may only

                                       51
<PAGE>   58

be the subject of an amendment, modification, or waiver if Borrower and Required
Lenders, and, in the case of any matter affecting Administrative Agent (except
as set forth above), Administrative Agent, have approved same; provided that no
such amendment or waiver shall, unless signed by each Lender directly affected
thereby, (i) increase the Commitment of such Lender, (ii) reduce the principal
of or rate of interest on any Borrowing or any fees or other amounts payable
hereunder, (iii) postpone any date fixed for the payment of any scheduled
installment of principal of or interest on any Borrowing or any fees or other
amounts payable hereunder or for termination of any of the Total Commitment, or
(iv) change the percentage of the Total Commitment or of the unpaid principal
amount of the Notes, or the number of Lenders, which shall be required for
Lenders or any of them to take any action under this SECTION 13.11(a) or any
other provision of this Agreement.

         (b) Any conflict or ambiguity between the terms and provisions herein
and terms and provisions in any other Loan Document shall be controlled by the
terms and provisions herein.

         (c) No course of dealing nor any failure or delay by any Credit Party
or any of its Representatives with respect to exercising any Right of any Credit
Party hereunder shall operate as a waiver thereof. A waiver must be in writing
and signed by Administrative Agent and Required Lenders (or by all Lenders, if
required hereunder) to be effective, and such waiver will be effective only in
the specific instance and for the specific purpose for which it is given.

         13.12 MULTIPLE COUNTERPARTS. This Agreement may be executed in a number
of identical counterparts, each of which shall be deemed an original for all
purposes and all of which constitute, collectively, one agreement; but, in
making proof of this Agreement, it shall not be necessary to produce or account
for more than one such counterpart. It is not necessary that each Lender execute
the same counterpart so long as identical counterparts are executed by Borrower,
each Lender, and Administrative Agent. This Agreement shall become effective
when counterparts hereof shall have been executed and delivered to
Administrative Agent by each Lender, Administrative Agent, and Borrower, or,
when Administrative Agent shall have received telecopied, telexed, or other
evidence satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

         13.13 SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS.

         (a) This Agreement shall be binding upon, and inure to the benefit of
the parties hereto and their respective successors and assigns, except that (i)
Borrower may not, directly or indirectly, assign or transfer, or attempt to
assign or transfer, any of its Rights, duties or obligations under any Loan
Documents without the express written consent of all Lenders, and (ii) except as
permitted under this SECTION 13.13, no Lender may transfer, pledge, assign, sell
any participation in, or otherwise encumber its portion of the Obligation.

         (b) Each Lender may assign to one or more Eligible Assignees all or a
portion of its Rights and obligations under this Agreement and the other Loan
Documents (including all or a portion of its Commitment, Borrowings, and its
Notes); provided, however, that:

                  (i) each such assignment shall be to an Eligible Assignee;

                  (ii) except in the case of an assignment to another Lender or
         an assignment of all of a Lender's Rights and obligations under this
         Agreement and the other Loan Documents, any such

                                       52

<PAGE>   59

         partial assignment shall be in an amount at least equal to $10,000,000
         or an integral multiple of $5,000,000 in excess thereof;

                  (iii) each such assignment by a Lender shall be of a constant,
         and not varying, percentage of all of its Rights and obligations under
         this Agreement and the Notes; and

                  (iv) the parties to such assignment shall execute and deliver
         to Administrative Agent for its acceptance an Assignment and Acceptance
         Agreement in the form of EXHIBIT E, together with any Notes subject to
         such assignment and a processing fee of $3,500.

Upon execution, delivery, and acceptance of such Assignment and Acceptance
Agreement, the assignee thereunder shall be a party hereto and, to the extent of
such assignment, have the obligations, Rights, and benefits of a Lender under
the Loan Documents and the assigning Lender shall, to the extent of such
assignment, relinquish its rights and be released from its obligations under the
Loan Documents. Upon the consummation of any assignment pursuant to this SECTION
13.13(b), the assignor, Administrative Agent, and Borrower shall make
appropriate arrangements so that, if required, new Notes are issued to the
assignor and the assignee. If the assignee is not incorporated under the Legal
Requirements of the United States of America or a state thereof, then it shall
deliver to Borrower and Administrative Agent certification as to exemption from
deduction or withholding of Taxes in accordance with SECTION 4.6.

         (c) Administrative Agent shall maintain at its address referred to in
SECTION 13.3 a copy of each Assignment and Acceptance Agreement delivered to and
accepted by it (and deliver a copy of each to Borrower) and a register for the
recordation of the names and addresses of Lenders and the Commitment, and
principal amount of the Borrowings owing to, each Lender from time to time (the
"REGISTER"). The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and Borrower, Administrative Agent, and Lenders
may treat each Person whose name is recorded in the Register as a Lender
hereunder for all purposes of this Agreement. The Register shall be available
for inspection by Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

         (d) Upon its receipt of an Assignment and Acceptance Agreement executed
by the parties thereto, together with any Notes subject to such assignment and
payment of the processing fee, Administrative Agent shall, if such Assignment
and Acceptance Agreement has been completed and is in substantially the form of
EXHIBIT E, (i) accept such Assignment and Acceptance Agreement, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to the parties thereto.

         (e) Each Lender may sell participations to one (1) or more Persons in
all or a portion of its Rights and obligations under this Agreement including
all or a portion of its Commitment, Borrowings, and Notes; provided, however,
that (i) such Lender's obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) the participant shall be entitled to
the benefit of the yield protection provisions in SECTION 4 and the right of
setoff in SECTION 3.12, and (iv) Borrower shall continue to deal solely and
directly with such Lender in connection with such Lender's Rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of Borrower relating to its Borrowings and its Notes and
to approve the amendment, modification, or waiver of any provision of this
Agreement (other than amendments, modifications, or waivers decreasing the
amount of principal of, or the rate at which interest is payable on, such
Borrowings or Notes, extending any scheduled principal payment date or date
fixed for the payment of interest on such Borrowings or Notes, or extending or
increasing its Commitment).

         (f) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time assign and pledge all or any portion of its
Borrowings and its Notes to any Federal Reserve Bank as collateral security
pursuant to Regulation A and any Operating Circular issued by such Federal
Reserve Bank. No such assignment shall release the assigning Lender from its
obligations hereunder.

         (g) Any Lender may furnish any information concerning the Companies in
the possession of such Lender from time to time to assignees and participants
(including prospective assignees and participants) to the extent such proposed
assignee or participant has executed a customary confidentiality agreement.

         13.14 DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES. The obligations of Borrower under the Loan Documents shall remain
in full force and effect until termination of the Total Commitment and payment
in full of the Principal Debt and of all interest, fees, and other amounts of
the Obligation then due and owing, except that SECTIONS 4, 11, and 13, and any
other provisions under the Loan Documents expressly intended to survive by the
terms hereof or by the terms of the applicable Loan Documents, shall survive
such termination. If at any time any payment of the principal of or interest on
any Note or any other amount payable by Borrower under any Loan Document is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy, or reorganization of any Company or otherwise, then the obligations
of Borrower under the Loan Documents with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

                               OPINION OF COUNSEL

         The opinion delivered by counsel to Borrower must be in form and
substance acceptable to Administrative Agent and its special counsel and cover
the following matters:

         1. Borrower is duly incorporated, validly existing, and in good
standing under the Legal Requirements of the State of Nevada.

         2. Borrower is duly qualified to transact business and is in good
standing as a foreign corporation in the State of Texas and in each other
jurisdiction where, to the best of that counsel's knowledge, the nature and
extent of Borrower's business and properties require due qualification and good
standing.

         3. Borrower possesses all requisite corporate power and authority to
conduct its business as is now being, or is contemplated by the Credit Agreement
to be, conducted.

         4. The execution and delivery by Borrower of each Loan Document to
which it is a party and the performance by it of its obligations thereunder, (a)
are within its corporate power, (b) have been duly authorized by all necessary
corporate action on its behalf, (c) except for any action or filing that has
been taken or made on or before the date of this opinion, and the filing of the
Loan Documents with the Securities and Exchange Commission pursuant to the
Securities Exchange Act of 1934, require no action by or filing with any
Governmental Authority, (d) do not violate any provision of its Constituent
Documents, (e) do not to the best knowledge of counsel after reasonable inquiry
violate any Legal Requirement applicable to it or, to the best knowledge of
counsel after reasonable inquiry, any material agreements to which it is a party
and of which counsel is aware, and (f) do not result in the creation or
imposition of any Lien on any asset of Borrower pursuant to a material agreement
of Borrower of which counsel is aware.

         5. Upon execution and delivery by all parties to it, each Loan Document
will constitute a legal and binding obligation of Borrower, enforceable against
it in accordance with its terms, except as enforceability may be limited by
applicable Debtor Relief Laws and general principles of equity.

         6. To the best knowledge of counsel after reasonable inquiry, (a) no
Company is subject to, or aware of the threat of, any Litigation that is
reasonably likely to be determined adversely to it and, if so adversely
determined, would be a Material Adverse Event, and (b) no outstanding or unpaid
judgments against any Company exist that could be a Material Adverse Event.

                   FORM OF ASSIGNMENT AND ACCEPTANCE AGREEMENT

         Reference is made to the Credit Agreement dated as of August 9, 2000
(as amended, modified, supplemented, or restated from time to time, the
"AGREEMENT") among CENTEX CORPORATION, a Nevada corporation ("BORROWER"), the
Lenders named therein (each such term as defined in the Agreement), and BANK OF
AMERICA, N.A., as Administrative Agent for Lenders ("ADMINISTRATIVE AGENT").
Capitalized terms used herein and not otherwise defined herein shall have the
meanings assigned to such terms in the Agreement.

         The "ASSIGNOR" and the "ASSIGNEE" referred to on SCHEDULE 1 agree as
follows:

         1. Assignor hereby sells and assigns to Assignee, without recourse and
without representation or warranty except as expressly set forth herein, and
Assignee hereby purchases and assumes from Assignor, an interest in and to
Assignor's Rights and obligations under the Agreement and the related Loan
Documents as of the date hereof equal to the percentage interest specified on
SCHEDULE 1. After giving effect to such sale and assignment, Assignor's and
Assignee's Commitment and the amount of the Borrowings under the Facility owing
to each of them will be as set forth on SCHEDULE 1.

         2. Assignor: (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties, or representations made in or in connection with the Loan Documents
or the execution, legality, validity, enforceability, genuineness, sufficiency,
or value of the Loan Documents or any other instrument or document furnished
pursuant thereto; (iii) makes no representation or warranty and assumes no
responsibility with respect to the financial condition of any party to any Loan
Document or the performance or observance by any such party of any of its
obligations under the Loan Documents or any other instrument or document
furnished pursuant thereto; and (iv) attaches the Notes held by Assignor and
requests that Administrative Agent exchange such Notes for new Notes. Such new
Notes shall be prepared in accordance with the provisions of SECTION 3.1(A) of
the Agreement and will reflect the respective Commitments of Assignee and
Assignor after giving effect to this Assignment and Acceptance.

         3. Assignee: (i) confirms that it has received a copy of the Agreement,
together with copies of the Current Financials and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment and Acceptance; (ii) agrees that it will,
independently and without reliance upon Administrative Agent, Assignor, or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Agreement; (iii) confirms that it is an Eligible
Assignee; (iv) appoints and authorizes Administrative Agent to take such action
as Administrative Agent on its behalf and to exercise such powers and discretion
under the Agreement as are delegated to Administrative Agent by the terms
thereof, together with such powers and discretion as are reasonably incidental
thereto; and (v) agrees that it will perform in accordance with their terms all
of the obligations that by the terms of the Agreement are required to be
performed by it as a Lender.

         4. Following the execution of this Assignment and Acceptance, it will
be delivered to Administrative Agent for acceptance and recording by
Administrative Agent. The effective date for this

<PAGE>   116

Assignment and Acceptance ("EFFECTIVE DATE") shall be the date of acceptance
hereof by Administrative Agent, unless otherwise specified on SCHEDULE 1.

         5. Upon such acceptance and recording by Administrative Agent, as of
the Effective Date, (i) Assignee shall be a party to the Agreement and, to the
extent provided in this Assignment and Acceptance, have the Rights and
obligations of a Lender thereunder, and (ii) Assignor shall, to the extent
provided in this Assignment and Acceptance, relinquish its Rights and be
released from its obligations under the Agreement.

         6. Upon such acceptance and recording by Administrative Agent, from and
after the Effective Date, Administrative Agent shall make all payments under the
Agreement, the Notes, and loan accounts in respect of the interest assigned
hereby (including, without limitation, all payments of principal, interest, and
commitment fees and other fees with respect thereto) to Assignee. Assignor and
Assignee shall make all appropriate adjustments in payments under the Agreement
and the other Loan Documents for periods prior to the Effective Date directly
between themselves.

         7. Unless Assignee is a Lender or an Affiliate of a Lender that meets
the requirements of CLAUSE (b) of the definition of "ELIGIBLE ASSIGNEE" in the
Agreement (and this sale and assignment is not made in connection with the sale
of such Affiliate), this Assignment and Acceptance is conditioned upon the
consent of Borrower and Administrative Agent pursuant to the definition of
"ELIGIBLE ASSIGNEE" in the Agreement. The execution and delivery of this
Assignment and Acceptance by Borrower and Administrative Agent is evidence of
this consent.

         8. As contemplated by SECTION 13.13(b)(iv) of the Agreement, Assignor
or Assignee (as determined between Assignor and Assignee) agrees to pay to
Administrative Agent for its account on the Effective Date in federal funds a
processing fee of $3,500.

         9. THIS ASSIGNMENT AND ACCEPTANCE SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE UNITED STATES OF
AMERICA AND THE STATE OF TEXAS.

         10. This Assignment and Acceptance may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of SCHEDULE 1 to this Assignment and Acceptance by telecopier shall
be effective as delivery of a manually executed counterpart of this Assignment
and Acceptance.

         IN WITNESS WHEREOF, Assignor and Assignee have caused SCHEDULE 1 to
this Assignment and Acceptance to be executed by their officers thereunto duly
authorized as of the date specified thereon.

and have an approximate value of $469,510 (the "Purchaser Shares").

                           The Cash Portion of the Purchase Price and the
Purchaser Shares are sometimes referred to collectively herein as the "Purchase
Price."

                  (b) Additional Consideration. On the Closing Date, Parent and
the Company shall deliver to Purchaser a list of the Business' outstanding
accounts receivables which are, as of the Closing Date, ninety or more days past
due (the "Delinquent Receivables"). The parties agree to use their best efforts
to maximize collections of the Delinquent Receivables following the Closing
Date. Any amounts paid by account debtors owing such Delinquent Receivables (the
"Delinquent Payments") shall first be applied to the oldest Delinquent
Receivable owed by such account debtor and fifty percent of such Delinquent
Payments shall be promptly paid by Purchaser to Parent; provided, however, any
adjustments to the Cash Portion of the Purchase Price whether up or down
pursuant to Section 2.5(c)(iv) hereof shall be paid from the Delinquent Payments
which shall not be split 50/50 until the Tangible Net Book Value adjustment
determined pursuant to Section 2.5(c)(iv) is completely recovered and then the
next Delinquent Payments shall be split 50/50. As an example, if the Tangible
Net Book Value is greater than Zero Dollars, such amount above Zero Dollars
shall be paid to Parent from the first Delinquent Payments and once such amount
has been paid the remaining Delinquent Payments shall be split 50/50 between the
Parent and Purchaser.

                  (c) Purchase Price Adjustment. On the Closing Date, Parent
shall deliver to Purchaser a balance sheet of the Business as of the close of
Business on the Closing Date (the "Closing Date Balance Sheet"). The Closing
Date Balance Sheet shall be prepared in accordance with GAAP, applied in a
manner consistent with the prior application of those principles.

                           (i) The Closing Date Balance Sheet shall include the
Acquired Assets as the only assets of the Business. The Acquired Assets shall be
recorded on the Closing Date Balance Sheet in accordance with GAAP, applied in a
manner consistent with the prior application of those principles, including
consistent application of estimated lives of property involved and depreciation
schedules and prepared without giving effect to the transactions contemplated by
this Agreement.

                           (ii) The Closing Date Balance Sheet shall include as
its only liabilities the Assumed Liabilities, recorded on the Closing Date
Balance Sheet in accordance with GAAP and applied in a manner consistent with
the prior application of those principles and prepared without giving effect to
the transactions contemplated by this Agreement.

                                      -7-
<PAGE>   9
                           (iii) The Closing Date Balance Sheet shall include a
proposed calculation of the Tangible Net Book Value of the Business.

                           (iv) The Parties acknowledge the Purchase Price being
paid by Purchaser hereunder has been calculated based on the assumption that the
Tangible Net Book Value of the Business reflected on the Closing Date Balance
Sheet will be Zero Dollars ($0). If the Tangible Net Book Value reflected on the
Closing Date Balance Sheet is less than Zero Dollars, then the Cash Portion of
the Purchase Price shall be decreased by an amount equal to the amount by which
such Tangible Net Book Value is less than Zero Dollars. In the event the
Tangible Net Book Value reflected on the Closing Date Balance Sheet is greater
than Zero Dollars, the Cash Portion of the Purchase Price shall be increased by
an amount equal to the amount by which such Tangible Net Book Value exceeds Zero
Dollars. Any such adjustments referred to in this clause (iv) shall be paid only
through the collection of Delinquent Receivables as set forth in Section 2.5(b)
hereof.

                  (d) Allocation of Purchase Price. Within 30 days after the
Closing Date, the parties in good faith shall agree as to how the Purchase Price
shall be allocated among the Acquired Assets. Each party agrees that it will use
such allocations for all Federal and State income tax reporting purposes and
that it will not, in its Tax Returns or elsewhere, take a position inconsistent
with the allocations provided for in this Section 2.5(d).

                  (e) Adjustments to Assumed Liabilities and Acquired Assets. If
within 60 days after the Closing Date, the parties determine in good faith that
there is an asset of the Business or a liability of the Business (which
liability was incurred in the ordinary course of business consistent with past
practice) which was inadvertently omitted from the Closing Date Balance Sheet,
the parties shall adjust the Closing Date Balance Sheet by the amount of such
liability or asset, which amount shall be agreed to in good faith by such
parties. Any such adjustments to the Closing Date Balance Sheet which result in
a change to the Tangible Net Book Value shall be paid solely from the next
Delinquent Payments which shall not be split 50/50 as provided for in Section
2.5(b) until such adjustment amount is completely recovered and then the parties
shall apply the remaining Delinquent Payments 50/50.

         Section 2.6 Assignment of Contracts. If any Contract to be assigned to
Purchaser hereunder requires the consent of a third party which has not been
obtained as of the Closing Date, this Agreement shall not be deemed to effect an
assignment of such Contract. Parent agrees that it will continue to use
commercially reasonable efforts to obtain the required consent to the assignment
of such Contracts. Unless and until such consent is obtained, Purchaser will
perform and fulfill, on a subcontractor basis, the obligations of Parent or the
Company to be performed under such Contracts on and after the Closing Date, and
Parent or the Company will remit to Purchaser all payments received under such
Contracts.

                  (a) On the Closing Date, Parent and the Company will take (or

offer employment, on an at-will basis, to all of the Continued Employees.
Purchaser shall offer compensation and benefit packages to each Continued
Employee substantially equivalent (in the aggregate) to the compensation and
benefit packages of such Continued Employee as of the date of this Agreement,
and the Continued Employees shall be given credit for seniority or service
purposes under Purchaser's employee benefit plans for the period of their
employment by Parent or the Company.

                  (b) Nothing contained in this Agreement shall obligate
Purchaser to retain for any period of time any Continued Employee.

         Section 6.4 Transfer Taxes; Expenses.

                  (a) Any sales taxes, real property transfer taxes or recording
fees or any other similar taxes or fees payable as a result of the sale of the
Acquired Assets or any other action contemplated by this Agreement or by any
Ancillary Agreement will be borne by the party on whom such taxes are imposed by
applicable law.

                  (b) Parent, the Company and Purchaser will cooperate in the
preparation, execution and filing of all returns, questionnaires, applications
or other documents regarding any real property transfer or gains, sales, use,

                  (a) For a period of three years following the Closing Date
(the "Non-Compete Term"), neither Parent nor the Company will directly or
indirectly, and will not permit any Covered Entity to, engage in the Business,
or acquire more than a 10% equity ownership interest in the Business, other than
as permitted by the License Agreement. A business or enterprise shall be deemed
to be "engaged in the Business" if more than 30% of the revenues of such
business or enterprise are generated by the Business. If a business or
enterprise is not engaged in the Business on the date Parent or the Company
becomes involved, but within twelve (12) months of the date of Parent or
Company's

                                      -18-
<PAGE>   20
acquisition commences to engage in the Business, Parent and/or the Company shall
have six months from the date of such commencement to dispose of its interest in
such business or enterprise or cause such business or enterprise to cease to
engage in the Business. If Parent or the Company acquires more than a 10% equity
interest in a business or enterprise that is generating less than 30% of its
revenues from office productivity software, Parent or the Company shall have a
period of six months from the date of acquisition to cause such business or
enterprise to cease or dispose of such portion of its business. "Affiliate(s)"
means any corporation, company, partnership, joint venture, firm and/or other
entity which Controls, is Controlled by or is under common Control with Parent
or the Company. "Control" means (a) in the case of corporate entities, direct or
indirect ownership of at least fifty percent (50%) of the stock or participating
shares entitled to vote for the election of directors; and (b) in the case of
non-corporate entities (such as limited liability companies, partnerships or
limited partnerships), either (x) direct or indirect ownership of at least fifty
percent (50%) of the equity interest or (y) the power to direct the management
and policies of the non-corporate entity. A "Covered Entity" shall mean every
Affiliate of Parent or the Company but shall not include any entity which
acquires Parent which immediately prior to such acquisition was engaged in the
Business. This covenant shall apply to each entity which is presently a Covered
Entity or which becomes a Covered Entity subsequent to the date of this
Agreement.

                  (b) This covenant shall apply to the entirety of the world
including, with respect to California, each of the counties in the State of
California listed on Schedule 6.5 hereto. The parties have agreed that it is
reasonable to have the provisions of this Section 6.5 apply to the entirety of
the world for various reasons, including, without limitation, that Parent or the
Company currently sells and distributes the products of the Business worldwide
and after the closing of the transactions contemplated by this Agreement,
Purchaser shall continue to sell and distribute the products of the Business in
the same manner.

         Section 6.6 No Solicitation. During the one-year period following the
Closing Date, (i) neither Parent nor the Company will directly or indirectly,
hire, solicit, take away, or attempt to hire, solicit or take away (either on
behalf of Parent or the Company, or any other person or entity) any person who
is then an employee of Purchaser, and (ii) Purchaser will not directly or
indirectly, hire, solicit, take away, or attempt to hire, solicit or take away
(either on behalf of Purchaser, or any other person or entity) any person who is
then an employee of Parent.

         Section 6.7 Confidentiality. From and after the date hereof, Parent and
Company shall treat in confidence all non-public documents, materials and other
information regarding the Business. However, nothing contained herein shall
prohibit Parent and Company from (i) using such documents, materials and other
information in connection with any action or proceeding brought or any claim
asserted by any party hereto in respect of any breach of any representation,
warranty or covenant made in or

                                      -19-
<PAGE>   21
pursuant to this Agreement, or (ii) supplying or filing such documents,
materials or other information to or with any Governmental Entity or other
Person which Parent and Company deems reasonably necessary in connection with
the obtaining of any consent, waiver, amendment, modification, approval,
authorization, permit or license which may be necessary to effectuate this
Agreement and to consummate the transactions contemplated hereby.

         Section 6.8 Reasonable Efforts and Further Assurances. Subject to the
terms and conditions hereof, the parties will use reasonable efforts to
effectuate the transactions contemplated hereby and by the Ancillary Agreements,
and to fulfill and cause to be fulfilled the conditions to Closing under this
Agreement. Subject to the terms and conditions hereof, each party hereto, at the
reasonable request of the other party, will execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary to consummate the transactions contemplated hereby and by the
Ancillary Agreements.

         Section 6.9 Post-Closing Cooperation. Following the Closing, each party
will deliver promptly to the other party all mail, checks and other documents
received by such party which relate to any of the business conducted by such
other party or its Affiliates after the Closing and Parent shall use
commercially reasonable efforts to obtain any consents set forth on Schedule
4.2(b) which are not obtained prior to the Closing Date.

         Section 6.10 Notices. From and after the date of this Agreement until
the Closing Date, each party hereto will promptly notify the other parties of
(i) the occurrence or nonoccurrence of any event, condition or development the
occurrence or nonoccurrence of which would be likely to materially adversely
affect the ability of such party to consummate the transactions contemplated
hereby and by the Ancillary Agreements and (ii) the failure of such party to
comply with any covenant or agreement to be complied with by it pursuant to this
Agreement which would be likely to result in any condition to the obligations of
such party to effect the transactions contemplated by this Agreement and by the
Ancillary Agreements not to be satisfied.

         Section 6.11 Cessation of Use of Name. From and after the Closing Date,
Purchaser shall have the right to use the name "VistaSource" or any derivative
thereof. In such regard, on the Closing Date Company shall change its name from
VistaSource to an unrelated name and Company and Parent shall cease using the
name "VistaSource" or any variation thereof in any manner.

         Section 6.12 Conduct of Business. During the period from the date of
this Agreement and continuing until the earlier of the termination of this
Agreement or the Closing Date, Parent and Company shall conduct the Business in
the ordinary course of business consistent with past practices, including,
without limitation, the timely payment of liabilities.

Parent and the Company will indemnify, defend and hold harmless Purchaser and
its Affiliates, each of their respective officers, directors, employees, agents,
shareholders, representatives and agents and each of the successors and assigns
of any of the foregoing (collectively, the "Purchaser Indemnified Parties")
from, against and in respect of any and all claims, liabilities, obligations,
losses, costs, expenses, penalties, fines and judgments (at equity or at law)
and damages whenever arising or incurred (including amounts paid in settlement,
costs of investigation and reasonable attorneys' fees and expenses) arising out
of or relating to:

                  (a) any breach or inaccuracy of any representation or warranty
made by Parent or the Company in this Agreement or any Ancillary Agreement;

                  (b) any breach of any covenant, agreement or undertaking made
by Parent or the Company in this Agreement or any Ancillary Agreement; and

                  (c) any Excluded Liability.

The claims, liabilities, obligations, losses, costs, expenses, penalties, fines
and damages of the Purchaser Indemnified Parties described in this Section 9.1
as to which the Purchaser Indemnified Parties are entitled to indemnification
under this Section 9.1 are hereinafter collectively referred to as "Purchaser
Losses."

                  (d) Liability Limits. Notwithstanding anything to the contrary
set forth herein, (i) Parent and the Company shall not be liable for any
Purchaser Losses in excess of Cash Portion of the Purchase Price paid to Parent
and the Company pursuant to Section 2.5(a)(i) hereof, as adjusted pursuant to
Section 2.5(c), (ii) Parent and the Company shall not be liable for any
Purchaser Losses unless and until the aggregate amount of the Purchaser Losses
exceeds $50,000 (at which point Parent and the Company shall become liable for
Purchaser Losses in excess of such $50,000), and (iii) the amount of any
Purchaser Losses shall be reduced by any insurance proceeds which a Purchaser
Indemnified Party has received with respect such Loss, it being agreed that each
Purchaser Indemnified Party shall use commercially reasonable efforts to assert
any insurance claims to which it is entitled; provided, however, that the
limitations in clause (ii) shall not apply to any breach or inaccuracy of any

covenant contained in Sections 2.5, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9 and 6.11 and
Article IX or any fraud or intentional misrepresentation of the parties. Subject

         Section 9.2 Indemnification Procedure.

                  (a) Upon becoming aware of any action, claim or proceeding, or
a threatened action, claim or proceeding, by a third party (a "Third Party
Claim") with respect to which a Purchaser Indemnified Party (hereinafter
referred to as an "Indemnified Party") may be entitled to make an
indemnification claim pursuant to Section 9.1 against the Parent or Company for
any Purchaser Losses, Indemnified Party must notify Company and Parent (the
"Indemnifying Party"), as promptly as practicable, but in any event within 10
days of the Indemnified Party's becoming aware of such Third Party Claim;
provided, however, that the failure of the Indemnified Party to so notify the
Indemnifying Party will not relieve the Indemnifying Party from liability for
such Third Party Claim arising under Section 9.1 unless the failure to so notify
the Indemnifying Party materially prejudices the ability of the Indemnifying
Party to assert defenses or counterclaims available to the Indemnified Party or
the Indemnifying Party with respect to such Third Party Claim.

                  (b) The Indemnifying Party will have the right, upon written
notice delivered to the Indemnified Party within 20 days thereafter, to defend
such Third Party Claim by all appropriate proceedings at its sole cost and
expense. If, however, the Indemnifying Party declines or fails to assume the
defense of such Third Party Claim within such 20 day period, then the
Indemnified Party may defend the Third Party Claim by all appropriate
proceedings, at the cost and expense of the Indemnifying Party, and may
vigorously and diligently prosecute such Third Party Claim to a final
conclusion. The party defending such Third Party Claim will have full control of
such defense, including the employment of counsel; provided, however, that if
requested by the party defending such Third Party Claim, the other party will
cooperate with the party defending such Third Party Claim.

                  (c) In any Third Party Claim with respect to which
indemnification is sought under Section 9.1, the party that is not defending
such Third Party Claim may participate in such Third Party Claim and retain its
own counsel at such party's own expense; provided, however, if there is a
conflict of interest between the Indemnified Party and the Indemnifying Party
with respect to such Third Party Claim such party may retain its own counsel at
the expense of the other party. The party defending the Third Party Claim will
at all times use reasonable efforts to keep the other party reasonably apprised
of the status of the defense of such Third Party Claim and to cooperate in the
defense of such Third Party Claim.

                  (d) The Indemnifying Party may not settle or compromise any
Third Party Claim or consent to the entry of any judgment with respect to such
Third Party Claim for which indemnification is being sought hereunder for
anything other than money damages without the prior written consent of the
Indemnified Party, which consent will not be unreasonably withheld. The
Indemnified Party may not settle or compromise any Third Party Claim or consent
to the entry of any judgment with respect

                                      -26-
<PAGE>   28
to such Third Party Claim for which indemnification is being sought hereunder
without the prior written consent of the Indemnifying Party, which consent will
not be unreasonably withheld.

                  (e) If an Indemnified Party claims a right to be indemnified
pursuant to this Agreement for Purchaser Losses that do not arise from a Third
Party Claim, then such Indemnified Party will promptly send written notice of
such claim to the Indemnifying Party. Such notice will specify the basis for
such claim in reasonable detail and be accompanied by such other information as
may be necessary for the Indemnifying Party to assess the merits and amount of
such claim. As promptly as possible after the Indemnified Party has given such
notice, the Indemnified Party and the Indemnifying Party will establish the
merits and amount of such claim (by mutual agreement, litigation, arbitration or
otherwise) and, within five (5) Business Days of the final determination of the
merits and amount of such claim, the Indemnifying Party will pay to the
Indemnified Party in immediately available funds an amount equal to such claim
as determined hereunder.

                  (f) Any indemnification payments made pursuant to this Article
IX shall be treated by the parties, to the extent permitted by applicable law,
as an adjustment to the Purchase Price for tax purposes.

         Section 9.3 Claims Period. For purposes of this Agreement, a "Claims
Period" is the period after the earlier of the Closing Date or the date of any
termination of this Agreement pursuant to Article VIII during which a claim for
indemnification may be asserted under this Agreement by an Indemnified Party.
The Claims Periods under this Agreement will terminate as follows:

                  (a) with respect to any breach or inaccuracy of any
representation or warranty in Sections 4.2, 4.3, 4.7 and 4.9 or any breach of
any agreement or covenant contained in Sections 2.5, 6.4, 6.5, 6.6, 6.7, 6.8,
6.9 and 6.11 and Article IX the Claims Period will continue indefinitely, except
as limited by law (including by applicable statutes of limitation); and

                  (b) with respect to all other Purchaser Losses (other than
Purchaser Losses described in clause (a) above) arising under this Agreement,
the Claims Period will terminate on the date that is one year after the Closing
Date.

                  Notwithstanding the foregoing, if prior to the close of
business on the last day of the applicable Claims Period, an Indemnifying Party
has been properly notified as provided hereunder of a claim for indemnity
hereunder and such claim has not been finally resolved or disposed of at such
date, such claim will continue to survive and will remain a basis for indemnity
hereunder until such claim is finally resolved or disposed of in accordance with
the terms hereof.

         Section 10.1 Interpretation.

                  (a) Whenever the words "include", "includes" or "including"
are used in this Agreement they are deemed to be followed by the words "without
limitation."

                  (b) The words "hereof", "hereby", "herein" and "herewith" and
words of similar import, unless otherwise stated, are construed to refer to this
Agreement as a whole and not to any particular provision of this Agreement, and
article, section, paragraph, exhibit, annex and schedule references are to the
articles, sections, paragraphs, exhibits, annexes and schedules of this
Agreement unless otherwise specified.

                  (c) The defined terms in this Agreement apply equally to both
the singular and plural forms of the terms defined, and words denoting any

its other grammatical forms has a corresponding meaning.

                  (d) Unless the context otherwise requires, any reference to
any agreement, other instrument, statute or regulation is to such agreement,
other instrument, statute or regulation as modified, amended or supplemented,
from time to time (and, in the case of a statute or regulation, to any successor
provision).

                  (e) The parties have participated jointly in the negotiation
and drafting of this Agreement. If an ambiguity or question of intent or
interpretation arises, this Agreement will be construed as if drafted jointly by
the parties, and no presumption or burden of proof will arise favoring or
disfavoring any party by virtue of the authorship of any provisions of this
Agreement.

or to such other persons or addresses as may be designated in writing by the
party to receive such notice. Nothing in this section is deemed to constitute

legal proceeding (including Litigation arising out of or in connection with this
Agreement), which service will be effected as required by applicable Law.

         Section 10.3 Headings. The table of contents and the headings contained
in this Agreement are for reference purposes only and will not affect in any way
the meaning or interpretation of this Agreement.

         Section 10.4 Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of Law
or public policy, then all other conditions and provisions of this Agreement
will nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to any party. Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto will negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that transactions contemplated hereby are fulfilled to the extent
possible.

         Section 10.5 Entire Agreement. This Agreement and the Ancillary
Agreements constitute the entire agreement of the Parties, and supersede all
prior agreements, representations and undertakings, both written and oral,
between the parties, with respect to the subject matter hereof (and thereof).

         Section 10.6 Assignment. No Party may, directly or indirectly, assign
this Agreement or any of its rights or obligations hereunder, by operation of
law or otherwise, without the prior written consent of the other parties hereto,
except Purchaser may assign its rights hereunder to an affiliate which is
controlled directly or indirectly by Parallax Capital Partners, LLC. Any
attempted assignment in violation of this Section 10.6 will be void and of no
effect.

         Section 10.7 Parties in Interest. This Agreement will be binding upon
and inure solely to the benefit of each of the parties and their respective
successors and permitted assigns, and nothing in this Agreement, express or
implied, is intended to or will confer upon any other Person any right, benefit
or remedy of any nature whatsoever under or by reason of this Agreement other
than the Purchaser Indemnified Parties to the extent provided in Article IX.

         Section 10.8 Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of any party in the exercise of any right hereunder
will impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty, agreement or covenant herein, nor
will any single or partial exercise of any such right preclude other or further
exercise thereof or of any other right.

         Section 10.9 Governing Law. This Agreement and the Ancillary
Agreements, instruments and documents contemplated hereby will be governed by
and construed in accordance with the Laws of the State of California.

         Section 10.10 Counterparts. This Agreement may be executed in multiple
counterparts, and by the different Parties hereto in separate counterparts, each
of which when executed will be deemed to be an original but all of which taken
together will constitute one and the same agreement.

         Section 10.11 Supplemental Disclosure Schedule. No later than five (5)
business days prior to the Closing, Parent and the Company may deliver
amendments or supplements to the Disclosure Schedules (including additions of
new sections thereof) for review and either approval thereof or rejection
thereof by Purchaser, which approval will not be unreasonably withheld or
delayed by Purchaser. To the extent that Purchaser approves any such amendment
or supplement to the Disclosure Schedules, the indemnification provisions set
forth in Article IX will not apply to any Purchaser Loss arising out of, based
upon or resulting from any matters that have been disclosed in such amendments
or supplements to the Disclosure Schedules.

         Section 10.12 Specific Performance. The parties acknowledge that money
damages would not be a sufficient remedy for any breach by any Party of its
obligation to proceed with the Closing under this Agreement or comply with the
covenants contained herein and that irreparable harm would result if this
Agreement were not specifically enforced. Therefore, the rights and obligations
of the parties under this Agreement may be enforceable by a decree of specific
performance issued by any court of competent jurisdiction, and appropriate
injunctive relief may be applied for and granted in connection therewith. A
party's right to specific performance is in addition to all other legal or
equitable remedies available to such Party.
