be at least ten (10) Business Days after Borrower's delivery of such notice). In
the event that the Total Commitment is reduced to zero and there is no

specified in SECTION 13.14, and all facility fees and other fees then earned and
unpaid hereunder and all other amounts of the Obligation then due and owing
shall be immediately due and payable, without notice or demand by any Credit
Party.

      2.4   BORROWING PROCEDURE. The following procedures apply to Borrowings
(other than Conversions and Continuations of Borrowings):

      (a)   NOTICE OF BORROWING. Each Borrowing shall be made pursuant to a
Notice of Borrowing delivered to Administrative Agent requesting that Lenders
fund a Borrowing on a Borrowing Date, which notice (i) shall be irrevocable and
binding on Borrower, (ii) shall specify the Borrowing Date, amount, Type, and
(for a Borrowing comprised of Eurodollar Borrowings) Interest Period, and (iii)
must be received by Administrative Agent no later than 11:00 a.m. on the third
(3rd) Business Day preceding the Borrowing Date for any Eurodollar Borrowing or
on the Borrowing Date for any Prime Rate Borrowing. Administrative Agent shall
promptly notify each Lender with respect to Administrative Agent's receipt of
each Notice of Borrowing.

      (b)   FUNDING. Each Lender shall remit its Pro Rata Part of each requested
Borrowing to Administrative Agent at its Payment Office in funds which are or
will be available for immediate use by Administrative Agent by 2:00 p.m. on the
Borrowing Date therefor. Subject to receipt of such funds, Administrative Agent
shall (unless to its actual knowledge any of the conditions precedent therefor
have not been satisfied by Borrower or waived by Required Lenders) make such
funds available to Borrower by causing such funds to be deposited by 3:00 p.m.
on the Borrowing Date to Borrower's account as designated to Administrative
Agent by Borrower. Notwithstanding the foregoing, unless Administrative

CREDIT AGREEMENT

                                       17
<PAGE>

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 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. The obligations of Lenders
hereunder to remit their Pro Rata Part of each requested Borrowing are several
and not joint. The failure of any Lender to make its Pro Rata Part of any
Borrowing on any date required hereunder shall not relieve any other Lender of
its corresponding obligation to do so on such date, and no Lender shall be
responsible for the failure of any other Lender to make its Pro Rata Part of any
Borrowing.

      2.5   EXTENSION OF TERMINATION DATE.

      (a)   Borrower may, not more than once during any period of twelve (12)
consecutive months, upon written notice to Administrative Agent (who shall
promptly notify Lenders) not less than ninety (90) days prior to the Termination
Date then in effect, request an extension of the Termination Date then in effect
(the "EXTENSION REQUEST"). Within thirty (30) days after receipt of such notice,
each Lender shall notify Administrative Agent by written notice whether or not
it consents to such extension. Any Lender not responding within the above time
period shall be deemed to have not consented to such extension. Administrative
Agent shall promptly notify Borrower of Lenders' responses and the aggregate
amount of the Commitments of Rejecting Lenders (the "REJECTED AMOUNT").

      (b)   The Termination Date then in effect shall be extended only if
Lenders ("ACCEPTING LENDERS") holding not less than seventy percent (70%) of the
Total Commitment (the amount of which shall be calculated prior to giving effect
to any removals or replacements of Rejecting Lenders) have consented thereto. If
so extended, the Termination Date then in effect shall be extended to a date 364
days from the Termination Date then in effect, effective as of the Termination
Date then in effect (the effective date of the extension being the "EXTENSION
EFFECTIVE DATE"). Administrative Agent shall promptly confirm in writing to
Lenders and Borrower such extension and the Extension Effective Date. As a
condition precedent to such extension, Borrower shall deliver to Administrative
Agent a certificate dated as of the Extension Effective Date (in sufficient
copies for each Accepting Lender) signed by a Responsible Officer (i) certifying
and attaching the resolutions adopted by Borrower approving or consenting to
such extension and (ii) certifying that, before and after giving effect to such
extension, no Potential Default or Event of Default exists. Administrative Agent
shall distribute an amended SCHEDULE 2.1 (which shall be deemed incorporated
into this Agreement) to reflect any changes in Lenders and their Commitments.

      (c)   If the Termination Date is extended as provided in SECTION 2.5(b)
and if any Lender (individually, a "REJECTING LENDER" and collectively,
"REJECTING LENDERS") declines, or is deemed to have

CREDIT AGREEMENT

                                       18
<PAGE>

declined, to consent to such extension, then the Commitment of such Rejecting
Lender shall automatically terminate on the Extension Effective Date (or such
earlier date by written notice from Borrower to Administrative Agent and such
Rejecting Lender at least three (3) Business Days prior to such termination).
Upon termination of the Commitment of any Rejecting Lender pursuant to the
foregoing sentence, Borrower shall pay to such Rejecting Lender (and the same
shall become due and payable) the outstanding Principal Debt owed by Borrower to
such Rejecting Lender, all interest thereon, and any other Obligation owed to
such Rejecting Lender (including pursuant to SECTION 4.5). Borrower shall have
the right, in consultation with and through Administrative Agent, to request to
add one or more Subsequent Lenders or Increasing Lenders pursuant to SECTION 2.2
to replace such Rejecting Lenders.

      (d)   This SECTION 2.5 shall supersede any provisions in SECTION 13.11 to
the contrary.

SECTION 3 TERMS OF PAYMENT.

      3.1   NOTES AND PAYMENTS.

      (a)   NOTES. The Principal Debt owed to each Lender shall be evidenced by
one or more accounts or records maintained by such Lender and by Administrative
Agent in the ordinary course of business. The accounts or records maintained by
Administrative Agent and each Lender shall be conclusive absent manifest error
of the amount of the Principal Debt owed to such Lender and the interest and
payments thereon. Any failure to so record or any error in doing so shall not,
however, limit or otherwise affect the obligation of Borrower hereunder to pay
any amount owing with respect to the Obligation. In the event of any conflict
between the accounts and records maintained by any Lender and the accounts and
records of Administrative Agent in respect of such matters, the accounts and
records of Administrative Agent shall control in the absence of manifest error.
Upon the request of any Lender made through Administrative Agent, Borrower shall
execute and deliver to such Lender (through Administrative Agent) a Note, which
shall evidence the Principal Debt owed to such Lender and shall be in the face
amount of such Lender's Commitment in addition to such accounts or records. Each
Lender may attach schedules to its Note and endorse thereon the date, Type (if
applicable), amount and maturity of Borrowings and payments with respect
thereto.

      (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,
defense, recoupment, or counterclaim, by 12:00 noon on the day due. Payments
made after 12:00 noon shall be deemed made on the Business Day next following.
If any payment or prepayment on the Obligation is stated to be due on a day that
is not a Business Day, such payment shall be due on the next following Business
Day, and, to the extent applicable, interest and fees shall continue to accrue
until such payment or prepayment is actually made. 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 12:00 noon, and otherwise before 12:00 noon 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 on the respective dates that fall every three (3)
months after the beginning of such Interest Period and on 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.

      (b)   MANDATORY PAYMENTS.

            (i)   The Total Principal Debt is due and payable on the 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. 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 11:00 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; 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. Administrative Agent
shall promptly notify each Lender of the contents of each Notice of Prepayment
upon its receipt.

      3.3   INTEREST OPTIONS. Except where specifically otherwise provided,
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. Each change in the Prime 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 the rates then in effect, but such
indicated rates shall neither be binding upon Administrative Agent or

CREDIT AGREEMENT

                                       20
<PAGE>

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 computations of interest for Prime Rate Borrowings shall be made
on the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed. All other computations of 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. 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
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,

CREDIT AGREEMENT

                                       21
<PAGE>

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 11:00 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; 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 promptly 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.

      (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,

CREDIT AGREEMENT

                                       22
<PAGE>

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 Total Principal Debt; (iii) to the ratable
payment of the Total Principal Debt; and (iv) 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 "BENEFITED 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, then
such Benefited 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
Benefited 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 Benefited
Lender, then such purchase shall be rescinded, and the purchase price and
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 or phase-in 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 Note, 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 Note 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 Note or any of such extensions of credit or liabilities
      or commitments;

and the result of any of the foregoing is or would be to increase the cost to
such Lender (or its Applicable Lending Office) of being obligated to make,
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 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 or phase-in 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

CREDIT AGREEMENT

                                       24
<PAGE>

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 and each Lender 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).

      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:

CREDIT AGREEMENT

                                       25
<PAGE>

      (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 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.

CREDIT AGREEMENT

                                       26
<PAGE>

      (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 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 referred to in the
foregoing SECTION 4.6(d) 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
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.

                                       29
<PAGE>

      (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

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
Borrower under the Existing Credit Facility; and (b) for lawful, corporate
purposes including, without limitation, liquidity support for commercial paper
issued by Borrower. 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.

      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

CREDIT AGREEMENT

                                       30
<PAGE>

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 or not prohibited 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 or not prohibited by the Loan
Documents), free and clear, in the case of all Restricted Subsidiaries, of any
Liens, restrictions (including restrictions on transfer), claims, or Rights of
another Person except for restrictions on transfer 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. No
Material Adverse Event has occurred from March 31, 2004 to the Closing Date.

      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 $25,000,000 (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 $25,000,000 or more
which is not either

CREDIT AGREEMENT

                                       31
<PAGE>

(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 against any Company
which is reasonably likely to be determined adversely and, if so adversely
determined, 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 a
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), and (e) no Reportable Event has occurred which is reasonably
likely to result in the termination of an Employee Plan, if such accumulated
funding deficiency, liability, withdrawal, prohibited transaction, or Reportable
Event is reasonably likely to result individually or in the aggregate in
liability on the part of Borrower in excess of $25,000,000. 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
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

CREDIT AGREEMENT

                                       32
<PAGE>

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 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 committed to make any Credit Extensions under this Agreement and thereafter

reference to "Restricted Subsidiary" in CLAUSE (II) of the first sentence of
SECTION 8.12(a) shall be deemed to read "newly formed or acquired Subsidiary").

      (c)   If, as of any date, the aggregate Recourse Debt of the Unrestricted
Subsidiaries (determined on a consolidated basis in accordance with GAAP)
exceeds the greater of (a) twenty-five percent (25%) of Consolidated Debt as of

Subsidiary or Subsidiaries to be a Restricted Subsidiary such that the aggregate
Recourse Debt of the remaining Unrestricted Subsidiaries does not exceed the
greater of (a) twenty-five percent (25%) of Consolidated Debt (including the
newly designated Restricted Subsidiary), or (b) $750,000,000. Borrower shall

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; provided that each Lender
reserves the Right to bring suit to recover Obligations owing to such Lender
after such Obligations become due and payable in the event Administrative Agent
or Required Lenders do not do so on its behalf.

      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 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.

<PAGE>

      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.
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 (i) to pay or reimburse Administrative Agent for all
reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation, negotiation, and execution of this Agreement and the
other Loan Documents and any amendment, waiver, consent, or other modification
of the provisions hereof and thereof (whether or not the transactions
contemplated hereby or thereby are consummated), and the consummation and
administration of the transactions contemplated hereby and thereby, including
all Attorney Costs, and (ii) to pay or reimburse Administrative Agent and each
Lender for all costs and expenses incurred in connection with the enforcement,
attempted enforcement, or preservation of any rights or remedies under this
Agreement or the other Loan Documents (including all such costs and expenses
incurred during any "workout" or restructuring in respect of the Obligation and
during any legal proceeding, including any proceeding under any Debtor Relief
Law), including all Attorney Costs. The foregoing costs and expenses shall
include all search, filing, recording, title insurance, and appraisal charges
and fees and taxes related thereto, and other out-of-pocket expenses incurred by
Administrative Agent and the cost of independent public accountants and other
outside experts retained by the Administrative Agent or any Lender. All amounts
due under this SECTION 11.10(a) shall be payable within ten (10) Business Days
after demand therefor. The agreements in this SECTION 11.10(a) shall survive the
termination of the Commitments and repayment of the Obligation.

      (b)   Whether or not the transactions contemplated hereby are consummated,
Borrower shall indemnify and hold harmless each Agent-Related Person, each
Lender and their respective Affiliates, directors, officers, employees, counsel,
agents, and attorneys-in-fact (collectively, "INDEMNITEES") from and against any
and all liabilities, obligations, losses, damages, penalties, claims, demands,
actions, judgments, suits, costs, expenses, and disbursements (including
Attorney Costs) of any kind or nature whatsoever which may at any time be
imposed on, incurred by or asserted against any such Indemnitee in any way
relating to or arising out of or in connection with (i) the execution, delivery,
enforcement, performance or administration of any Loan Document or any other
agreement, letter or instrument delivered in connection with the transactions
contemplated thereby or the consummation of the transactions contemplated
thereby, (ii) any Commitment, Borrowing, or the use or proposed use of the
proceeds therefrom, or (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property currently or formerly owned or
operated by Borrower or any Subsidiary, or any liability under Environmental Law
related in any way to Borrower or any Subsidiary, or (iv) any actual or
prospective claim, litigation, investigation, or proceeding relating to any of
the foregoing, whether based on contract, tort, or any other theory (including
any investigation of, preparation for, or defense of any pending or threatened
claim, investigation, litigation, or proceeding) and regardless of whether any
Indemnitee is a party thereto (all the foregoing, collectively, the "INDEMNIFIED
LIABILITIES"), IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN
PART, OUT OF THE NEGLIGENCE OF THE INDEMNITEE; provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such
liabilities, obligations, losses, damages, penalties, claims, demands, actions,
judgments, suits, costs, expenses, or disbursements are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence, bad faith, or willful misconduct of such Indemnitee. No
Indemnitee shall be liable for any damages arising from the use by others of any
information or other materials obtained through IntraLinks or other similar
information transmission systems in connection with this Agreement, nor shall
Borrower or any Indemnitee have any liability for any indirect, punitive, or
consequential damages relating to this Agreement or any other Loan Document or
arising out of its activities in connection herewith or therewith (whether
before or after the Closing Date). All amounts due under this SECTION 11.10(b)
shall be payable within ten (10) Business Days after demand therefor. The
agreements in this SECTION 11.10(b) shall survive the resignation of
Administrative Agent, the replacement of any Lender, the termination of the
Commitments, and the repayment, satisfaction or discharge of the Obligation.

SECTION 12 ADMINISTRATIVE AGENT.

      12.1  APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each Lender
hereby irrevocably appoints, designates, and authorizes Administrative Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Administrative Agent agrees to: (a) make available promptly after the date of
this Agreement to any Lender copies of all Loan Documents in its possession
which are requested by any such Lender, and (b) timely distribute to each Lender
all material information (including financial statements), requests, documents,
and items received from Borrower under the Loan Documents. Notwithstanding any
provision to the contrary contained elsewhere herein or in any other Loan
Document, Administrative Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall Administrative Agent have or
be deemed to have any fiduciary relationship with any Lender or participant, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against Administrative Agent. Without limiting the generality of
the foregoing sentence, the use of the term "agent" herein and in the other Loan
Documents with reference to

CREDIT AGREEMENT

                                       46
<PAGE>

Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable Law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

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

      12.3  LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person shall (a)
be liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct
in connection with its duties expressly set forth herein), or (b) be responsible
in any manner to any Lender or participant for any recital, statement,
representation or warranty made by any Company or any officer thereof, contained
herein or in any other Loan Document, or in any certificate, report, statement,
or other document referred to or provided for in, or received by Administrative
Agent under or in connection with, this Agreement or any other Loan Document, or
the validity, effectiveness, genuineness, enforceability, or sufficiency of this
Agreement or any other Loan Document, or for any failure of any Company or any
other party to any Loan Document to perform its obligations hereunder or
thereunder. No Agent-Related Person shall be under any obligation to any Lender
or participant to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books, or records of any
Company or any Affiliate thereof.

      12.4  RELIANCE BY ADMINISTRATIVE AGENT.

      (a)   Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, electronic mail message, statement, or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons, and upon advice
and statements of legal counsel (including counsel to any Company), independent
accountants and other experts selected by Administrative Agent. Administrative
Agent shall be fully justified in failing or refusing to take any action under
any Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders as it deems appropriate and, if it so requests, it shall
first be indemnified to its satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. Administrative Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Loan Document in accordance with a request or consent of the Required
Lenders (or such greater number of Lenders as may be expressly required hereby
in any instance) and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders.

      (b)   For purposes of determining compliance with the conditions specified
in SECTION 6.01, each Lender that has signed this Agreement shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter required thereunder to be consented to or approved by or
acceptable or satisfactory to a Lender unless Administrative Agent shall have
received notice from such Lender prior to the proposed Closing Date specifying
its objection thereto.

CREDIT AGREEMENT

                                       47
<PAGE>

      12.5  NOTICE OF EVENT OF DEFAULT. Administrative Agent shall not be deemed
to have knowledge or notice of the occurrence of any Event of Default, except
with respect to defaults in the payment of principal, interest, and fees
required to be paid to Administrative Agent for the account of the Lenders,
unless Administrative Agent shall have received written notice from a Lender or
Borrower referring to this Agreement, describing such Event of Default and
stating that such notice is a "notice of default." Administrative Agent will
notify Lenders of its receipt of any such notice and of its giving of notice to
Borrower pursuant to SECTIONS 10.2(B) or (C). Administrative Agent shall take
such action with respect to such Event of Default as may be directed by the
Required Lenders in accordance with SECTION 10; provided, however, that unless
and until Administrative Agent has received any such direction, Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Event of Default as it shall deem
advisable or in the best interest of the Lenders.

      12.6  CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE AGENT.
Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by Administrative Agent
hereafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Company or any Affiliate thereof, shall be deemed
to constitute any representation or warranty by any Agent-Related Person to any
Lender as to any matter, including whether Agent-Related Persons have disclosed
material information in their possession. Each Lender represents to
Administrative Agent that it has, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial, and other condition and
creditworthiness of the Companies, and all applicable bank or other regulatory
Legal Requirements relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to Borrower
hereunder. Each Lender also represents that it will, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals, and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial, and other condition and creditworthiness of Borrower.
Except for notices, reports, and other documents expressly required to be
furnished to Lenders by Administrative Agent herein, Administrative Agent shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, prospects, operations, property,
financial, and other condition or creditworthiness of any Companies or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

      12.7  INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, Lenders shall indemnify upon
demand each Agent-Related Person (to the extent not reimbursed by or on behalf
of any Company and without limiting the obligation of any Company to do so), Pro
Rata, and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided, however, that no Lender shall
be liable for the payment to any Agent-Related Person of any portion of such
Indemnified Liabilities to the extent the same shall have been determined in a
final, nonappealable judgment by a court of competent jurisdiction to have
resulted from such Agent-Related Person's own gross negligence or willful
misconduct; provided, however, that no action taken in accordance with the
directions of the Required Lenders shall be deemed to constitute gross
negligence or willful misconduct for purposes of this SECTION 12.7. Without
limitation of the foregoing, each Lender shall reimburse Administrative Agent
upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by Administrative Agent in

CREDIT AGREEMENT

                                       48
<PAGE>

connection with the preparation, execution, delivery, administration,
modification, amendment, or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that Administrative Agent
is not reimbursed for such expenses by or on behalf of Borrower. The undertaking
in this SECTION 12.7 shall survive termination of the Aggregate Commitments, the
payment of the Obligation and the resignation of Administrative Agent.

      12.8  ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. Administrative
Agent and its Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from, and generally engage in any kind of banking,
trust, financial advisory, underwriting, or other business with each Company and
its respective Affiliates as though Administrative Agent were not Administrative
Agent and without notice to or consent of Lenders. Lenders acknowledge that,
pursuant to such activities, Administrative Agent or its Affiliates may receive
information regarding any Company or its Affiliates (including information that
may be subject to confidentiality obligations in favor of such Company or such
Affiliate) and acknowledge that Administrative Agent shall be under no
obligation to provide such information to them. With respect to Borrowings,
Administrative Agent shall have the same rights and powers under this Agreement
as any other Lender and may exercise such rights and powers as though it were
not Administrative Agent, and the terms "Lender" and "Lenders" include
Administrative Agent in its individual capacity.

      12.9  SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may resign as
Administrative Agent upon thirty (30) days' notice to Lenders. If Administrative
Agent resigns under this Agreement, the Required Lenders shall appoint from
among Lenders a successor administrative agent for Lenders, which successor
administrative agent shall be consented to by Borrower at all times other than
during the existence of an Event of Default (which consent of Borrower shall not
be unreasonably withheld or delayed). If no successor administrative agent is
appointed prior to the effective date of the resignation of Administrative
Agent, Administrative Agent may appoint, after consulting with Lenders and with
the consent of Borrower at all times other than during the existence of an Event
of Default (which consent of Borrower shall not be unreasonably withheld or
delayed), a successor administrative agent from among Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, the
Person acting as such successor administrative agent shall succeed to all the
rights, powers, and duties of the retiring Administrative Agent, and the term
"Administrative Agent" shall mean such successor administrative agent, and the
retiring Administrative Agent's appointment, powers, and duties as
Administrative Agent shall be terminated without any other or further act or
deed on the part of such retiring Administrative Agent or any other Lender.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this SECTION 12 and SECTION 11.10 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under this Agreement. If no successor administrative
agent has accepted appointment as Administrative Agent by the date which is
thirty (30) days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
thereupon become effective and the Lenders shall perform all of the duties of
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above.

      12.10 ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIMS. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition, or other judicial
proceeding relative to any Company, Administrative Agent (irrespective of
whether the principal of any Borrowing shall then be due and payable as herein
expressed or by declaration or otherwise and irrespective of whether
Administrative Agent shall have made any demand on Borrower) shall be entitled
and empowered, by intervention in such proceeding or otherwise:

CREDIT AGREEMENT

                                       49
<PAGE>

      (a)   to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Borrowings and any other Obligation
that are owing and unpaid and to file such other documents as may be necessary
or advisable in order to have the claims of Lenders and Administrative Agent
(including any claim for the reasonable compensation, expenses, disbursements,
and advances of Lenders and Administrative Agent and their respective agents and
counsel and all other amounts due Lenders and Administrative Agent under
SECTIONS 5 and 11.10) allowed in such judicial proceeding; and

      (b)   to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to Administrative Agent and, in the event that
Administrative Agent shall consent to the making of such payments directly to
the Lenders, to pay to Administrative Agent any amount due for the reasonable
compensation, expenses, disbursements and advances of Administrative Agent and
its agents and counsel, and any other amounts due Administrative Agent under
SECTIONS 5 and 11.10.

Nothing contained herein shall be deemed to authorize Administrative Agent to
authorize or consent to or accept or adopt on behalf of any Lender any plan of
reorganization, arrangement, adjustment, or composition affecting the Obligation
or the rights of any Lender or to authorize Administrative Agent to vote in
respect of the claim of any Lender in any such proceeding.

      12.11 OTHER AGENT; ARRANGERS; AND MANAGERS. No Lender or other Persons
identified on the facing page or signature pages of this Agreement as a
"syndication agent," "documentation agent," "book manager," "arranger," or "lead
arranger" shall have any right, power, obligation, liability, responsibility, or
duty under this Agreement other than, in the case of such Lenders, those
applicable to all Lenders as such. Without limiting the foregoing, no Lender or
other Person so identified shall have or be deemed to have any fiduciary
relationship with any Lender. Each Lender acknowledges that it has not relied,
and will not rely, on any Lenders or other Persons so identified in deciding to
enter into this Agreement or in taking or not taking action hereunder.

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.

      13.3  COMMUNICATIONS.

      (a)   GENERAL. Unless otherwise expressly provided herein, all notices and
other communications provided for hereunder shall be in writing (including by
facsimile transmission). All such written notices shall be mailed, faxed, or
delivered to the applicable address, facsimile number, or (subject to SECTION
13.3(c) below) electronic mail address, and all notices and other communications
expressly permitted hereunder to be given by telephone shall be made to the
applicable telephone number specified for such Person on SCHEDULE 2.1 or to such
other address, facsimile number, electronic mail address, or telephone number as
shall be designated by such party in a notice to the other parties. All such
notices and other communications shall be deemed to be given or made upon the
earlier to occur of (i) actual receipt by the relevant party hereto and (ii) (A)
if delivered by hand or by courier, when signed for by or on behalf of the
relevant party hereto; (B) if delivered by mail, four (4) Business Days after
deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent
and receipt has been confirmed by telephone; and (D) if delivered by electronic
mail (which form of delivery is subject to the provisions of SECTION 13.3(c)
below), when delivered; provided, however, that notices and other communications
to Administrative Agent pursuant to SECTION 2 shall not be effective until
actually received by Administrative Agent. In no event shall a voicemail message
be effective as a notice, communication or confirmation hereunder.

      (b)   EFFECTIVENESS OF FACSIMILE DOCUMENTS AND SIGNATURES. Loan Documents
may be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on all Companies,
Administrative Agent, and Lenders. Administrative Agent may also require that
any such documents and signatures be confirmed by a manually-signed original
thereof; provided, however, that the failure to request or deliver the same
shall not limit the effectiveness of any facsimile document or signature.

      (c)   LIMITED USE OF ELECTRONIC MAIL. Electronic mail and Internet and
intranet websites may be used only to distribute routine communications and to
distribute Loan Documents for execution by the parties thereto, and may not be
used for any other purpose.

      (d)   RELIANCE BY ADMINISTRATIVE AGENT AND LENDERS. Administrative Agent
and Lenders shall be entitled to rely and act upon any notices (including
telephonic Notices of Borrowing) purportedly given by or on behalf of Borrower
even if (i) such notices were not made in a manner specified herein, were
incomplete or were not preceded or followed by any other form of notice
specified herein, or (ii) the terms thereof, as understood by the recipient,
varied from any confirmation thereof. Borrower shall indemnify each
Agent-Related Person and each Lender from all losses, costs, expenses, and
liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of Borrower. All telephonic notices to and
other communications with Administrative Agent may be recorded by Administrative
Agent, and each of the parties hereto hereby consents to such recording.

      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.

<PAGE>

      13.6  SURVIVAL. All covenants, agreements, undertakings, representations,
and warranties made in any of the Loan Documents shall survive the execution and
delivery thereof and all closings under the Loan Documents. All such
representations and warranties have been or will be relied upon by
Administrative Agent and each Lender regardless of any investigation made by
Administrative Agent or any Lender or on their behalf and notwithstanding that
Administrative Agent or any Lender may have had notice or knowledge of any
Potential Default or Event of Default at the time of any Borrowing and shall
continue in full force and effect as long as any Borrowing or other Obligation
is outstanding. 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

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

      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 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 (other than the Fee Letter) may only
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,
(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, or (v) amend, modify or waive this SECTION
13.11(a) or the Pro Rata or ratable treatment of Lenders under 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.

CREDIT AGREEMENT

                                       53
<PAGE>

      (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)   The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that Borrower may not assign or otherwise transfer any
of its rights or obligations hereunder without the prior written consent of each
Lender and no Lender may assign or otherwise transfer any of its rights or
obligations hereunder except (i) to an Eligible Assignee in accordance with the
provisions of SECTION 13.13(b), (ii) by way of participation in accordance with
the provisions of SECTION 13.13(d), or (iii) by way of pledge or assignment of a
security interest subject to the restrictions of SECTION 13.13(f). Nothing in
this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby, Participants to the extent provided in SECTION 13.13(d) and,
to the extent expressly contemplated hereby, the Indemnitees) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

      (b)   Any Lender may at any time assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment and outstanding Borrowings at the time owing
to it); provided that: (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender's Commitment and outstanding Borrowings
at the time owing to it or in the case of an assignment to a Lender or an
Affiliate of a Lender or an Approved Fund (as defined in SECTION 13.13(g)) with
respect to a Lender, the aggregate amount of the Commitment (which for this
purpose includes Borrowings outstanding thereunder) subject to each such
assignment, determined as of the date the Assignment and Assumption with respect
to such assignment is delivered to Administrative Agent or, if "Trade Date" is
specified in the Assignment and Assumption, as of the Trade Date, shall not be
less than $5,000,000 or a whole multiple of $500,000 in excess thereof, and
after such assignment, no Lender shall hold a Commitment of less than $5,000,000
unless each of Administrative Agent and, so long as no Event of Default has
occurred and is continuing, Borrower otherwise consents (each such consent not
to be unreasonably withheld or delayed); (ii) each partial assignment shall be
made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement with respect to the Borrowings or
the Commitment assigned; (iii) any assignment of a Commitment must be approved
by Administrative Agent (which approval shall not be unreasonably withheld)
unless the Person that is the proposed assignee is itself a Lender (whether or
not the proposed assignee would otherwise qualify as an Eligible Assignee); and
(iv) the parties to each assignment shall execute and deliver to Administrative
Agent an Assignment and Assumption, together with a processing

CREDIT AGREEMENT

                                       54

and recordation fee of $3,500. Subject to acceptance and recording thereof by
Administrative Agent pursuant to SECTION 13.13(c), from and after the effective
date specified in each Assignment and Assumption, the Eligible Assignee
thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of SECTIONS 4.1, 4.5, and 4.6 (with respect to
facts and circumstances occurring prior to the effective date of such
assignment) and 11.10). Upon request, Borrower (at its expense) shall execute
and deliver a Note to the assignee Lender. Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this subsection shall be treated for purposes of this Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with
SECTION 13.13(d).

      (c)   Administrative Agent, acting solely for this purpose as an agent of
Borrower, shall maintain at Administrative Agent's office a copy of each
Assignment and Assumption delivered to it and a register for the recordation of
the names and addresses of Lenders, and the Commitments of, and principal
amounts of the Borrowings owing to, each Lender pursuant to the terms hereof
from time to time (the "REGISTER"). The entries in the Register shall be
conclusive in the absence of manifest error, and Borrower, Administrative Agent,
and Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by Borrower and any Lender, at any reasonable time and
from time to time upon reasonable prior notice.

      (d)   Any Lender may at any time, without the consent of, or notice to,
Borrower or Administrative Agent, sell participations to any Person (other than
a natural person or Borrower or any of Borrower's Affiliates or Subsidiaries)
(each, a "PARTICIPANT") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or Borrowings owing to it); provided 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, and (iii) Borrower, Administrative Agent, and the other Lenders
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification, or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
waiver or other modification described in the first proviso to SECTION 13.11(a)
that directly affects such Participant. Subject to SECTION 13.13(e), Borrower
agrees that each Participant shall be entitled to the benefits of SECTIONS 4.1,
4.5, and 4.6 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to SECTION 13.13(b).

      (e)   A Participant shall not be entitled to receive any greater payment
under SECTIONS 4.1 or 4.5 than the applicable Lender would have been entitled to
receive with respect to the participation sold to such Participant, unless the
sale of the participation to such Participant is made with Borrower's prior
written consent. A Participant that would be a Lender that is not a "United
States person" within the meaning of Section 7701(a)(30) of the Tax Code, if it
were a Lender shall not be entitled to the benefits of SECTION 4.6 unless
Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of Borrower, to comply with SECTION 4.6 as
though it were a Lender.

CREDIT AGREEMENT

                                       55

      (f)   Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including under its Note,
if any) to secure obligations of such Lender, including any pledge or assignment
to secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

      (g)   As used herein, the following terms have the following meanings:

      APPROVED FUND means any Fund that is administered or managed by (a) a
      Lender, (b) an Affiliate of a Lender, or (c) an entity or an Affiliate of
      an entity that administers or manages a Lender.

      ELIGIBLE ASSIGNEE means: (a) a Lender; (b) an Affiliate of a Lender; (c)
      an Approved Fund; and (d) any other Person (other than a natural person)
      approved by (i) Administrative Agent, and (ii) unless an Event of Default
      has occurred and is continuing, Borrower (each such approval not to be
      unreasonably withheld or delayed); provided that notwithstanding the
      foregoing, "Eligible Assignee" shall not include Borrower or any of
      Borrower's Affiliates or Subsidiaries.

      FUND means any Person (other than a natural person) that is (or will be)
      engaged in making, purchasing, holding or otherwise investing in
      commercial loans and similar extensions of credit in the ordinary course
      of its business.

      (h)   Notwithstanding anything to the contrary contained herein, any
Lender that is a Fund may create a security interest in all or any portion of
the Borrowings owing to it and the Note, if any, held by it to the trustee for
holders of obligations owed, or securities issued, by such Fund as security for
such obligations or securities, provided that unless and until such trustee
actually becomes a Lender in compliance with the other provisions of this
SECTION 13.13, (i) no such pledge shall release the pledging Lender from any of
its obligations under the Loan Documents and (ii) such trustee shall not be
entitled to exercise any of the rights of a Lender under the Loan Documents even
though such trustee may have acquired ownership rights with respect to the
pledged interest through foreclosure or otherwise.

      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.

      13.15 LIMITED WAIVER. Each of the Lenders hereunder that is a Lender under
the Existing Credit Facility hereby waives the requirement set forth in Section
2.3 of the Existing Credit Facility that Borrower provide ten (10) Business Days
prior notice of the termination of the commitments thereunder. The waiver set
forth herein is limited as provided herein and shall not be deemed to be a
waiver or consent to any deviation from the terms of this Agreement or the other
Loan Documents.

      13.16 CONFIDENTIALITY. Each of Administrative Agent and Lenders agrees to
maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its

CREDIT AGREEMENT

                                       56
<PAGE>

and its Affiliates' directors, officers, employees, and agents, including
accountants, legal counsel, and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority
(including any self-regulatory authority, such as the National Association of
Insurance Commissioners), (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
hereto, (e) in connection with the exercise of any remedies hereunder or under
any other Loan Document or any action or proceeding relating to this Agreement
or any other Loan Document or the enforcement of rights hereunder or thereunder,
(f) subject to an agreement containing provisions substantially the same as
those of this SECTION 13.16, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to Borrower and its
obligations, (g) with the consent of Borrower, or (h) to the extent such
Information (x) becomes publicly available other than as a result of a breach of
this SECTION 13.16 or (y) becomes available to Administrative Agent or any
Lender on a nonconfidential basis from a source other than Borrower. For
purposes of this Section, "INFORMATION" means all information received from any
Company relating to any Company or any of their respective businesses, other
than any such information that is available to Administrative Agent or any
Lender on a nonconfidential basis prior to disclosure by any Company, provided
that, in the case of information received from a Company after the date hereof,
such information is clearly identified at the time of delivery as confidential.
Any Person required to maintain the confidentiality of Information as provided
in this SECTION 13.16 shall be considered to have complied with its obligation
to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

      13.17 USA PATRIOT ACT NOTICE. Each Lender and Administrative Agent (for
itself and not on behalf of any Lender) hereby notify Borrower that pursuant to
the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed
into law October 26, 2001)) (the "ACT"), it is required to obtain, verify and
record information that identifies Borrower, which information includes the name
and address of Borrower and other information that will allow such Lender or
Administrative Agent, as applicable, to identify Borrower in accordance with the
Act.

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

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
