                                 THE COMMITMENTS

         Each Lender severally but not jointly agrees to extend credit to the
Borrower in accordance with the following provisions and subject to the other
terms and conditions of the Credit Documents.

         SECTION 2.1. REVOLVING FACILITY.

         Each Borrowing is subject to all of the provisions in the Credit
Documents, including the following: (a) each Borrowing may occur only on a
Business Day on or after the Closing Date and before the Termination Date and
(b) the Borrowings may never exceed the total Commitments at such time.

         SECTION 2.2. BORROWING PROCEDURE.

         The following procedures apply to Borrowings:

         (a) BORROWING REQUEST. The Borrower may request a Borrowing by making
or delivering a Borrowing Request to the Administrative Agent, which is
irrevocable and binding on the Borrower, stating the Type, amount, and Interest
Period for each Borrowing and which must be received by the Administrative Agent
no later than (i) 10:00 a.m. on the third Business Day before the date on which
funds are requested (the "BORROWING DATE") for any LIBOR Rate Borrowing, or (ii)
11:00 a.m. on the Borrowing Date for any Base Rate Borrowing. The Administrative
Agent shall promptly on the day received notify each Lender of any Borrowing
Request. Each LIBOR Rate Borrowing must be in the amount of $10,000,000 or an
integral multiple of $1,000,000 in excess of $10,000,000, and each Base Rate
Borrowing must be in the amount of $1,000,000 or an integral multiple of
$100,000 in excess of $1,000,000, or if less than $1,000,000, the total unused
Commitments.

         (b) FUNDING. Each Lender shall remit its Commitment Percentage of each
requested Borrowing to the Administrative Agent's principal office in Atlanta,
Georgia, in funds that are available for immediate use by the Administrative
Agent by 2:00 p.m. on the applicable Borrowing Date. Subject to receipt of those
funds, the Administrative Agent shall (unless to its

<PAGE>   24
                                                                              19

actual knowledge any of the applicable conditions precedent have not been
satisfied by the Borrower or waived by the requisite Lenders) make those funds
available to the Borrower by wiring the funds to or for the account of the
Borrower.

         (c) FUNDING ASSUMED. Absent contrary written notice from a Lender, the
Administrative Agent may assume that each Lender has made its Commitment
Percentage of the requested Borrowing available to the Administrative Agent on
the applicable Borrowing Date, and the Administrative Agent may, in reliance
upon such assumption (but shall not be required to), make available to the
Borrower a corresponding amount. If a Lender fails to make its Commitment
Percentage of any requested Borrowing available to the Administrative Agent on
the applicable Borrowing Date, the Administrative Agent may recover the
applicable amount on demand (i) from that Lender together with interest,
commencing on the Borrowing Date and ending on (but excluding) the date the
Administrative Agent recovers the amount from that Lender, at an annual interest
rate equal to the Fed Funds Rate, or (ii) if that Lender fails to pay its amount
upon demand, then from the Borrower, together with interest at the rate
applicable to that Borrowing. No Lender is responsible for the failure of any
other Lender to make its share of any Borrowing available as required by Section
2.2(b); however, failure of any Lender to make its share of any Borrowing so
available does not excuse any other Lender from making its share of any
Borrowing so available.

         SECTION 2.3. EFFECT OF REQUESTS.

         Each Borrowing Request constitutes a representation and warranty by the
Borrower that as of the date of the requested Borrowing all of the applicable
conditions precedent in Article 5 have been satisfied.

         SECTION 2.4. TERMINATION OF THE COMMITMENTS.

         (a) VOLUNTARY. The Borrower may, upon giving at least five Business
Days prior written and irrevocable notice to the Administrative Agent, terminate
all or part of the Commitments. Each partial termination under this subsection
(a) must be in an amount of not less than $5,000,000 or a greater integral
multiple of $1,000,000 and must be ratable in accordance with each Lender's
Commitment Percentage.

         (b) MANDATORY. On the date of any prepayment of Borrowings pursuant to
Section 3.2(c)(ii), the Commitments shall automatically reduce by an amount
equal to such prepayment.

         (c) MISCELLANEOUS. At the time of any termination of the Commitments
under this Section 2.4, the Borrower shall pay to the Administrative Agent, for
the account of each Lender, as applicable, all accrued and unpaid fees under
this Agreement, the interest attributable to the amount of that reduction, and
any related Funding Loss. Any part of the Commitments that is terminated may not
be reinstated.

         SECTION 2.5. RENEWAL OF COMMITMENTS.

         (a) At least 45 but not more than 60 days prior to the then-current
Termination Date, the Borrower may, by delivering a written request to the
Administrative Agent (each such request being irrevocable), request that the
then-current Termination Date be extended for an

<PAGE>   25
                                                                              20

additional period of 364 days, commencing on the then-current Termination Date.
Upon receipt of such notice, the Administrative Agent shall promptly communicate
such request to the Lenders.

         (b) No earlier than 45 days prior, and no later than 30 days prior, to
the then-current Termination Date, the Lenders shall indicate to the
Administrative Agent whether the Borrower's request to so extend the
then-current Termination Date is acceptable to the Lenders, it being understood
that the determination by each Lender will be in its sole and absolute
discretion and that the failure of any Lender to so respond within such period
shall be deemed to constitute a refusal by such Lender to consent to such
request, with the result being that such request is denied (any Lender refusing
or deemed to refuse any such request, a "NON-CONSENTING LENDER"). The
Administrative Agent shall notify the Borrower, in writing, of the Lenders'
decisions no later than 15 days prior to the end of the then-current Termination
Date.

         (c) Subject to the satisfaction of the conditions set forth in Section
5.2, in the event that the sum of the Commitments of the Lenders that have
consented to the Borrower's request to extend the then-current Termination Date
(the "CONSENTING LENDERS") plus the Commitments of Non-Consenting Lenders with
respect to such request that have been assigned pursuant to Section 14.10(d)
hereof shall constitute at least 80% of the aggregate Commitments, the
then-current Termination Date shall be extended for an additional period of 364
days with respect to the Commitments of such Consenting Lenders. The Commitments
of Non-Consenting Lenders with respect to such request shall automatically
terminate on the last day of the then-current Termination Date (and the
principal amount of all Borrowings made by such Non-Consenting Lenders, together
with accrued interest and fees to such date, shall be repaid), unless assigned
pursuant to Section 14.10(d) hereof; provided that, before the Borrower may
solicit any institution other than the Consenting Lenders, the Consenting
Lenders shall, at least five days before the end of the then-current Termination
Date, determine whether to purchase by assignment the Commitments of such
Non-Consenting Lenders.

         (d) The Administrative Agent shall prepare and deliver to the Borrower
and each Lender (including each new bank and other financial institution to
which a Non-Consenting Lender's Commitment has been assigned pursuant to Section
14.10(d)) a revised Schedule 2 that reflects the Commitments of each Lender.

                                  ARTICLE III
                                  PAYMENT TERMS

         SECTION 3.1. NOTES AND PAYMENTS.

         The Borrowings are evidenced by the Notes, one payable to each Lender
in the amount of its Commitment. The Borrower must make each payment and
prepayment on the Obligations to the Administrative Agent's principal office in
Atlanta, Georgia, in immediately available funds by 1:00 p.m. on the day due;
otherwise, but subject to Section 3.6, that portion of the Obligations in
respect of which such payment or prepayment was made shall continue to accrue
interest until the Business Day upon which such payment shall be received by the
Administrative Agent at the time and in the manner specified above. The
Administrative Agent shall promptly pay to each Lender the part of any payment
or prepayment to which that Lender is entitled under this

<PAGE>   26
                                                                              21

Agreement on the same day the Administrative Agent receives the funds from the
Borrower. Unless the Administrative Agent has received notice from the Borrower
before the date on which any payment is due under this Agreement that the
Borrower will not make that payment in full, then on the date that payment is
due the Administrative Agent may assume that the Borrower has made the full
payment due and the Administrative Agent may, in reliance upon that assumption,
cause to be distributed to each Lender on that date the amount then due to each
Lender. If and to the extent the Borrower does not make the full payment due to
the Administrative Agent, each Lender shall repay to the Administrative Agent on
demand the amount distributed to that Lender by the Administrative Agent
together with interest for each day from the date that Lender received payment
from the Administrative Agent until the date that Lender repays the
Administrative Agent (unless such repayment is made on the same day as such
distribution), at an interest rate equal to the Fed Funds Rate.

         SECTION 3.2. INTEREST AND PRINCIPAL PAYMENTS.

         (a) INTEREST. Accrued interest on each LIBOR Rate Borrowing shall be
due and payable on the last day of its Interest Period. If any Interest Period
for a LIBOR Rate Borrowing is greater than three months, then accrued interest
shall also be due and payable on the date three months after the commencement of
the Interest Period. Accrued interest on the unpaid principal amount of each
Base Rate Borrowing shall be due and payable in arrears on the last day of each
March, June, September and December, commencing on the first such date that
follows the Closing Date, and on the date such Borrowing becomes due and payable
or is otherwise paid in full.

         (b) PRINCIPAL. The principal amount of all Borrowings shall be due and
payable on the Termination Date.

         (c) PREPAYMENTS.

                  (i) The Borrower may, from time to time, by giving notice to
         the Administrative Agent no later than three Business Days before the
         date of the prepayment, prepay, without premium or penalty and in whole
         or part, the principal amount of any Borrowing so long as:

                           (A) the notice by the Borrower specifies the amount
                  and Borrowing to be prepaid,

                           (B) each voluntary partial prepayment must be in a
                  principal amount of not less than $1,000,000 or a greater
                  integral multiple of $1,000,000, plus accrued interest on the
                  amount prepaid to the date of such prepayment, and

                           (C) the Borrower shall pay the Funding Loss, if any,
                  within 5 Business Days following an affected Lender's demand
                  and delivery to the Borrower of the certificate as provided in
                  Section 3.18. Conversions on the last day of Interest Period
                  pursuant to Section 3.10 are not prepayments.

                  (ii) The Borrower shall promptly notify the Administrative
         Agent upon the receipt of any Net Cash Proceeds and, at any time that
         Net Cash Proceeds received and

<PAGE>   27
                                                                              22

         not previously applied to any prepayment pursuant to this Section
         3.2(c)(ii) shall equal or exceed $10,000,000, the Borrower shall prepay
         Borrowings, together with payment of any Funding Losses, in an
         aggregate amount equal to 100% (without duplication) of the following
         amounts, with such prepayments to be applied as specified below:

                           (A) 100% of the Net Cash Proceeds of any Asset
                  Disposition or Recovery Event, to be applied to the
                  Borrowings; and

                           (B) 100% of the Net Cash Proceeds of any Equity
                  Event, to be applied, to the Borrowings.

                  (iii) If at any time, the sum of the aggregate principal
         amount of Borrowings shall exceed the total Commitments, the Borrower
         shall forthwith prepay Borrowings, in a principal amount equal to such
         excess, together with accrued interest to the date of such prepayment
         on the principal amount of Borrowings prepaid and any Funding Losses
         owing in connection therewith.

                  (iv) Prepayments of the Borrowings pursuant to this Section
         3.2(c) shall be applied, first, to prepay any amounts outstanding under
         the Other Facility (other than in the case of prepayments pursuant to
         3.2(c)(iii)), second, to prepay Base Rate Borrowings, third, to prepay
         any LIBOR Rate Borrowing that has an Interest Period the last day of
         which is the same as the date of such requirement prepayment, and,
         fourth to prepay other LIBOR Rate Borrowings, as selected by the
         Borrower, or, at the Borrower's option, to cash collateralize such
         other LIBOR Rate Borrowings (which cash collateral will be applied on
         the last day of the Interest Period of each such LIBOR Rate Borrowing
         to prepay such LIBOR Rate Borrowings).

         SECTION 3.3. INTEREST OPTIONS.

         Except as otherwise provided in this Agreement, Borrowings shall bear
interest at an annual rate equal to the lesser of (i) the Base Rate or the LIBOR
Rate plus the Applicable Margin, in each case as designated or deemed designated
by the Borrower, and (ii) the Maximum Rate; provided that the LIBOR Rate may not
be selected when an Event of Default or Potential Default has occurred and is
continuing.

         SECTION 3.4. QUOTATION OF RATES.

         The Borrower may contact the Administrative Agent prior to delivering a
Borrowing Request to receive an indication of the interest rates then in effect,
but the indicated rates do not bind the Administrative Agent or the Lenders or
affect the interest rate that is actually in effect when the Borrower makes a
Borrowing Request or on the Borrowing Date.

         SECTION 3.5. DEFAULT RATE.

         To the extent lawful, any amount payable under any Credit Document that
is not paid when due (including interest on any such unpaid amount) shall bear
interest from the date due (stated or by acceleration) at the Default Rate until
paid, regardless whether payment is made before or after entry of a judgment,
payable on demand.

<PAGE>   28
                                                                              23

         SECTION 3.6. INTEREST RECAPTURE.

         If the designated interest rate applicable to any amount exceeds the
Maximum Rate, the interest rate on that amount is limited to the Maximum Rate,
but any subsequent reductions in the designated rate shall not reduce the
interest rate thereon below the Maximum Rate until the total amount of accrued
interest equals the amount of interest that would have accrued if that
designated rate had always been in effect. If at maturity (stated or by
acceleration), or at final payment of the Notes, the total interest paid or
accrued is less than the interest that would have accrued if the designated
rates had always been in effect, then, at that time and to the extent lawful,
the Borrower shall pay an amount equal to the difference between (a) the lesser
of the amount of interest that would have accrued if the designated rates had
always been in effect and the amount of interest that would have accrued if the
Maximum Rate had always been in effect, and (b) the amount of interest actually
paid or accrued on the Notes.

         SECTION 3.7. INTEREST AND FEE CALCULATIONS.

         All computations of interest based on the prime lending rate of the
Administrative Agent shall be made by the Administrative Agent on the basis of a
year of 365 or 366 days, as the case may be. All computations of facility fees
and interest based on the LIBOR Rate or the Fed Funds Rate shall be made by the
Administrative Agent on the basis of a year of 360 days for the actual number of
days (including the first day but excluding the last day) occurring in the
period for which such facility fees or interest are payable. Each determination
by the Administrative Agent of an interest rate hereunder shall be conclusive
and binding for all purposes, absent manifest error.

         SECTION 3.8. MAXIMUM RATE.

         Regardless of any provision contained in any Credit Document, no Lender
is entitled to contract for, charge, take, reserve, receive or apply, as
interest on all or any part of the Obligations, any amount in excess of the
Maximum Rate, and, if any Lender ever does so, then any excess shall be treated
as a partial prepayment of principal (without regard to Section 3.9) and any
remaining excess shall be refunded to the Borrower. In determining if the
interest paid or payable exceeds the Maximum Rate, the Borrower and the Lenders
shall, to the maximum extent lawful, (a) characterize any nonprincipal payment
as an expense, fee or premium rather than as interest, (b) exclude voluntary
prepayments and their effects, and (c) amortize, prorate, allocate and spread
the total amount of interest throughout the entire contemplated term of the
relevant Borrowings. However, if the Obligations are paid in full before the end
of their full contemplated term, and if the interest received for the period
that the Obligations were outstanding exceeds the Maximum Amount, then the
Lenders shall refund any excess (and the Lenders may not, to the extent lawful,
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). If the Legal Requirements of the State of Texas are applicable for
purposes of determining the "Maximum Rate" or the "Maximum Amount", then those
terms mean the "indicated rate ceiling" from time to time in effect under
Chapter 303 of the Texas Finance Code. The Borrower agrees that Chapter 346 of
the Texas Finance Code (which regulates certain revolving credit loan accounts
and revolving tri-party accounts) does not apply to any Borrowings.

<PAGE>   29
                                                                              24

         SECTION 3.9. INTEREST PERIODS.

         When the Borrower requests a LIBOR Rate Borrowing, the Borrower may
elect the applicable interest period (each an "INTEREST PERIOD"), which may be,
at the Borrower's option, one, two, three or six months for LIBOR Rate
Borrowings, subject to Section 14.1 and the following conditions: (a) the
initial Interest Period for a LIBOR Rate Borrowing commences on the applicable
Borrowing Date or conversion date, and each subsequent Interest Period
applicable to any Borrowing commences on the day when the next preceding
applicable Interest Period expires; (b) if any Interest Period for a LIBOR Rate
Borrowing begins on a day for which no numerically corresponding Business Day in
the calendar month at the end of the Interest Period exists, then the Interest
Period ends on the last Business Day of that calendar month; (c) if the Borrower
is required to pay any portion of a LIBOR Rate Borrowing before the end of its
Interest Period in order to comply with the payment provisions of the Credit
Documents, the Borrower shall also pay any related Funding Loss; and (d) no more
than six Interest Periods may be in effect at one time.

         SECTION 3.10. CONVERSIONS.

         The Borrower may in accordance with the procedures set forth below (a)
convert a LIBOR Rate Borrowing on the last day of the applicable Interest Period
to a Base Rate Borrowing, (b) convert a Base Rate Borrowing at any time to a
LIBOR Rate Borrowing, and (c) elect a new Interest Period for a LIBOR Rate
Borrowing to commence upon expiration of the then-current Interest Period;
provided that the Borrower may not convert to or select a new Interest Period
for a LIBOR Rate Borrowing at any time when an Event of Default or Potential
Default has occurred and is continuing. Any such conversion or election may be
made by telephonic request to the Administrative Agent no later than 10:00 a.m.
on the third Business Day before the conversion date or the last day of the
Interest Period, as the case may be (for conversion to a LIBOR Rate Borrowing or
election of a new Interest Period), and no later than 11:00 a.m. on the last day
of the Interest Period (for conversion to a Base Rate Borrowing). The Borrower
shall provide a Conversion Notice to the Administrative Agent no later than two
days after the date of the conversion or election. Absent the Borrower's
telephonic request for conversion or election of a new Interest Period or if an
Event of Default or Potential Default has occurred and is continuing, then, a
LIBOR Rate Borrowing shall be deemed converted to a Base Rate Borrowing
effective when the applicable Interest Period expires.

         SECTION 3.11. ORDER OF APPLICATION.

         Each payment (including proceeds from the exercise of any Rights) of
the Obligations shall be applied either (a) if no Event of Default or Potential
Default has occurred and is continuing, then in the order and manner specified
elsewhere herein, and if not so specified, then in the order and manner as the
Borrower directs, or (b) if an Event of Default or Potential Default has
occurred and is continuing or if the Borrower fails to give any direction
required under clause (a) above, then in the following order: (i) to all fees,
expenses, and indemnified amounts for which the Administrative Agent has not
been paid or reimbursed in accordance with the Credit Documents and, except
while an Event of Default under Section 11.1 has occurred and is continuing, as
to which the Borrower has been invoiced and has failed to pay within ten
Business Days of that invoice; (ii) to all fees, expenses and indemnified
amounts for which any Lender has

<PAGE>   30
                                                                              25

not been paid or reimbursed in accordance with the Credit Documents (and if any
payment is less than all unpaid or unreimbursed fees and expenses, then that
payment shall be applied against unpaid and unreimbursed fees and expenses in
the order of incurrence or due date) and, except while an Event of Default under
Section 11.1 has occurred and is continuing, as to which the Borrower has been
invoiced and has failed to pay within ten Business Days of that invoice; (iii)
to accrued interest on the principal amount of the Borrowings outstanding; (iv)
to the principal amount of the Borrowings outstanding in such order as the
Required Lenders may elect (but the Lenders agree to apply proceeds in an order
that will minimize any Funding Loss); and (v) to the remaining Obligations in
the order and manner the Required Lenders deem appropriate.

         SECTION 3.12. SHARING OF PAYMENTS, ETC.

         Except as otherwise specifically provided, (a) principal and interest
payments on Borrowings shall be shared by the Lenders in accordance with their
respective Commitment Percentages and (b) each other payment on the Obligations
shall be shared by the Lenders in the proportion that the Obligations are owed
to the Lenders on the date of the payment. If any Lender obtains any payment or
prepayment with respect to the Obligations (whether voluntary, involuntary or
otherwise, including, without limitation, as a result of exercising its Rights
under Section 3.13) that exceeds the part of that payment or prepayment that it
is then entitled to receive under the Credit Documents, then that Lender shall
purchase from the other Lenders participations that will cause the purchasing
Lender to share the excess payment or prepayment ratably with each other Lender.
If all or any portion of any excess payment or prepayment is subsequently
recovered from the purchasing Lender, then the purchase shall be rescinded and
the purchase price restored to the extent of the recovery. The Borrower agrees
that any purchase of a participation in any Borrowing from a Lender may, to the
fullest extent lawful, exercise all of its Rights of payment (including the
Right of offset) with respect to that participation as fully as if that
purchaser were the direct creditor of the Borrower in the amount of that
participation.

         SECTION 3.13. OFFSET.

         If an Event of Default has occurred and is continuing, each Lender is
entitled to exercise (for the benefit of all the Lenders) the Rights of offset
and banker's Lien against each and every account and other property, or any
interest therein, that the Borrower or any Company, other than an Excluded
Subsidiary, may now or hereafter have with, or which is now or hereafter in the
possession of, that Lender to the extent of the full amount of the Obligations
then matured and owed (directly or participated) to it.

         SECTION 3.14. BOOKING BORROWINGS.

         To the extent lawful, any Lender may make, carry or transfer its
Borrowings at, to or for the account of any of its branch offices or the office
or branch of any of its Affiliates. However, no Affiliate or branch is entitled
to receive any greater payment under Section 3.16 than the transferor Lender
would have been entitled to receive with respect to those Borrowings, and a
transfer may not be made if, as a direct result of it, Section 3.16 or 3.17
would apply to any of the Obligations. If any of the conditions of Sections 3.16
or 3.17 ever apply to a Lender, that Lender shall, to the extent possible, carry
or transfer its Borrowings at, to or for the account of

<PAGE>   31
                                                                              26

any of its branch offices or the office or branch of any of its Affiliates so
long as the transfer is consistent with the other provisions of this section,
does not create any burden or adverse circumstance for that Lender that would
not otherwise exist, and eliminates or ameliorates the conditions of Section
3.16 or 3.17 as applicable.

         SECTION 3.15. BASIS UNAVAILABLE OR INADEQUATE FOR LIBOR RATE.

         If, on or before any date when a LIBOR Rate is to be determined for a
Borrowing, the Administrative Agent reasonably determines that the basis for
determining the applicable rate is not available or any Lender reasonably
determines that the resulting rate does not accurately reflect the cost to that
Lender of making or converting Borrowings at that rate for the applicable
Interest Period, then the Administrative Agent shall promptly notify the
Borrower and the Lenders of that determination (which is conclusive and binding
on the Borrower absent manifest error) and the applicable Borrowing shall bear
interest at the sum of the Base Rate plus the Applicable Margin. Until the
Administrative Agent notifies the Borrower that those circumstances no longer
exist, the Lenders' commitments under this Agreement to make, or to convert to,
LIBOR Rate Borrowings, as the case may be, are suspended.

         SECTION 3.16. ADDITIONAL COSTS.

         (a) RESERVES. With respect to any LIBOR Rate Borrowing (i) if any
change in any present Legal Requirement, any change in the interpretation or
application of any present Legal Requirement, or any future Legal Requirement
imposes, modifies or deems applicable (or if compliance by any Lender with any
requirement of any Governmental Authority results in) any requirement that any
reserves (including, without limitation, any marginal, emergency, supplemental
or special reserves) be maintained (other than any reserve included in the LIBOR
Reserve Percentage), and (ii) if those reserves reduce any sums receivable by
that Lender under this Agreement or increase the costs incurred by that Lender
in advancing or maintaining any portion of any LIBOR Rate Borrowing, then (A)
that Lender (through the Administrative Agent) shall deliver to the Borrower a
certificate setting forth in reasonable detail the calculation of the amount
necessary to compensate it for its reduction or increase (which certificate is
conclusive and binding absent manifest error), and (B) the Borrower shall pay
that amount to that Lender within five Business Days after demand. The
provisions of and undertakings and indemnification in this subsection (a)
survive the satisfaction and payment of the Obligations and termination of this
Agreement.

         (b) CAPITAL ADEQUACY. With respect to any Borrowing, if any change in
any present Legal Requirement (whether or not having the force of law), any
change in the interpretation or application of any present Legal Requirement
(whether or not having the force of law), or any future Legal Requirement
(whether or not having the force of law) regarding capital adequacy, or if
compliance by any Lender with any request, directive or requirement imposed in
the future by any Governmental Authority regarding capital adequacy, or if any
change by any Lender, its holding company, or its applicable lending office in
its written policies or in the risk category of this transaction, in any of the
foregoing events or circumstances, reduces the rate of return on its capital as
a consequence of its obligations under this Agreement to a level below that
which it otherwise could have achieved (taking into consideration its policies
with respect to capital adequacy) by an amount deemed by it to be material (and
it may, in determining the amount,

<PAGE>   32
                                                                              27

utilize reasonable assumptions and allocations of costs and expenses and use any
reasonable averaging or attribution method), then (unless the effect is already
reflected in the rate of interest then applicable under this Agreement) the
Administrative Agent or that Lender (through the Administrative Agent) shall
notify the Borrower and deliver to the Borrower a certificate setting forth in
reasonable detail the calculation of the amount necessary to compensate it
(which certificate is conclusive and binding absent manifest error), and the
Borrower shall pay that amount to the Administrative Agent or that Lender within
five Business Days after demand. The provisions of and undertakings and
indemnification in this subsection (b) shall survive the satisfaction and
payment of the Obligations and termination of this Agreement.

         (c) TAXES. Subject to Section 3.19, any Taxes payable by the
Administrative Agent or any Lender or ruled (by a Governmental Authority)
payable by the Administrative Agent or any Lender in respect of this Agreement
or any other Credit Document shall, if permitted by Legal Requirement, be paid
by the Borrower, together with interest and penalties, if any, except for Taxes
payable on or measured by the overall net income or capital of the
Administrative Agent or that Lender (or the Administrative Agent or that Lender,
as the case may be, together with any other Person with whom the Administrative
Agent or that Lender files a consolidated, combined, unitary or similar Tax
return) and except for interest and penalties incurred as a result of the gross
negligence or willful misconduct of the Administrative Agent or any Lender. The
Administrative Agent or that Lender (through the Administrative Agent) shall
notify the Borrower and deliver to the Borrower a certificate setting forth in
reasonable detail the calculation of the amount of payable Taxes, which
certificate is conclusive and binding (absent manifest error), and the Borrower
shall pay that amount to the Administrative Agent for its account or the account
of that Lender, as the case may be within five Business Days after demand. If
the Administrative Agent or that Lender subsequently receives a refund of the
Taxes paid to it by the Borrower, then the recipient shall promptly pay the
refund to the Borrower.

         SECTION 3.17. CHANGE IN LEGAL REQUIREMENTS.

         If any Legal Requirement makes it unlawful for any Lender to make or
maintain LIBOR Rate Borrowings, then that Lender shall promptly notify the
Borrower and the Administrative Agent, and (a) as to undisbursed funds, that
requested Borrowing shall be made as a Base Rate Borrowing, and (b) as to any
outstanding Borrowing, (i) if maintaining the Borrowing until the last day of
the applicable Interest Period is unlawful, then the Borrowing shall be
converted to a Base Rate Borrowing as of the date of notice, in which event the
Borrower will not be required to pay any related Funding Loss, or (ii) if not
prohibited by Legal Requirement, then the Borrowing shall be converted to a Base
Rate Borrowing as of the last day of the applicable Interest Period, or (iii) if
any conversion will not resolve the unlawfulness, then the Borrower shall
promptly prepay the Borrowing, without penalty but with related Funding Loss.

         SECTION 3.18. FUNDING LOSS.

         The Borrower shall indemnify each Lender against, and pay to it within
five Business Days following demand and delivery by such Lender to the Borrower
of the certificate herein provided, any Funding Loss of that Lender. When any
Lender demands that the Borrower pay any Funding Loss, that Lender shall deliver
to the Borrower and the Administrative Agent a certificate setting forth in
reasonable detail the basis for imposing Funding Loss and the

<PAGE>   33
                                                                              28

calculation of the amount, which calculation is conclusive and binding absent
manifest error. The provisions of and undertakings and indemnification in this
section survive the satisfaction and payment of the Obligations and termination
of this Agreement.

         SECTION 3.19. FOREIGN LENDERS, PARTICIPANTS AND ASSIGNEES.

         Each Lender, Participant (by accepting a participation interest under
this Agreement) and Assignee (by executing an Assignment) that is not organized
under the Legal Requirements of the United States of America or one of its
states (a) represents to the Administrative Agent and the Borrower that (i) no
Taxes are required to be withheld by the Administrative Agent or the Borrower
with respect to any payments to be made to it in respect of the Obligations and
(ii) it has furnished to the Administrative Agent and the Borrower two duly
completed copies of either U.S. Internal Revenue Service Form W-8BEN or W-8ECI
or any other form acceptable to the Administrative Agent and the Borrower that
entitles it to a complete exemption from U.S. federal withholding Tax on all
interest or fee payments under the Credit Documents, and (b) covenants to (i)
provide the Administrative Agent and the Borrower a new Form W-8BEN or W-8ECI or
other form acceptable to the Administrative Agent and the Borrower upon the
expiration or obsolescence according to Legal Requirement of any previously
delivered form, duly executed and completed by it, entitling it to a complete
exemption from U.S. federal withholding Tax on all interest and fee payments
under the Credit Documents, and (ii) comply from time to time with all Legal
Requirements with regard to the withholding Tax exemption. If any of the
foregoing is not true at any time or the applicable forms are not provided, then
the Borrower and the Administrative Agent (without duplication) may deduct and
withhold from interest and fee payments under the Credit Documents any Tax at
the maximum rate under the IRC or other applicable Legal Requirement, and
amounts so deducted and withheld shall be treated as paid to that Lender,
Participant or Assignee, as the case may be, for all purposes under the Credit
Documents.

         SECTION 3.20. DISCHARGE AND REINSTATEMENT.

         Each Company's obligations under the Credit Documents remain in full
force and effect until no Lender has any commitment to extend credit under the
Credit Documents and the Obligations are fully paid (except for provisions under
the Credit Documents which by their terms expressly survive payment of the
Obligations and termination of the Credit Documents). If any payment under any
Credit Document is ever rescinded or must be restored or returned for any
reason, then all Rights and obligations under the Credit Documents in respect of
that payment are automatically reinstated as though the payment had not been
made when due.

                                      FEES

         SECTION 4.1. TREATMENT OF FEES.

         The fees described in this Section 4.1 (a) are not compensation for the
use, detention or forbearance of money, (b) are in addition to, and not in lieu
of, interest and expenses otherwise described in this Agreement, (c) are payable
in accordance with Section 3.1, (d) are non-

<PAGE>   34
                                                                              29

refundable and (e) to the fullest extent permitted by Legal Requirement, bear
interest, if not paid when due, at the Default Rate.

         SECTION 4.2. FACILITY FEE.

         The Borrower shall pay to the Administrative Agent for the account of
each Lender the Facility Fee from the date hereof until the Termination Date,
payable on the last day of each March, June, September and December, commencing
on the first such date that follows the Closing Date, and on the Termination
Date.

                                   ARTICLE V
                              CONDITIONS PRECEDENT

         SECTION 5.1. CONDITIONS PRECEDENT TO CLOSING.

         This Agreement shall not be effective unless the Administrative Agent
has received all of the items described in Schedule 5. In addition, no Lender is
obligated to fund (as opposed to continue or convert) any Borrowing unless on
the date of the applicable Borrowing (and after giving effect to the requested
Borrowing): (a) the Administrative Agent has timely received a properly
completed and duly executed Borrowing Request; (b) all of the representations
and warranties of the Companies in the Credit Documents are true and correct in
all material respects (unless they speak to a specific date or are based on
facts which have changed by transactions contemplated or expressly permitted by
this Agreement); (c) no Material Adverse Event, Event of Default or Potential
Default has occurred and is continuing; and (d) no limitation in Section 2.1 is
or would be exceeded by the requested Borrowing. Each Borrowing Request, however
delivered, constitutes the Borrower's representation and warranty that the
conditions in subsections (b) through (d) above are satisfied. Upon the
Administrative Agent's or any Lender's reasonable request, the Borrower shall
deliver to the Administrative Agent or such Lender evidence substantiating any
of the matters in the Credit Documents that are necessary to enable the Borrower
to qualify for the requested Borrowing. Each condition precedent in this
Agreement (including, without limitation, those on Schedule 5) is material to
the transactions contemplated by this Agreement, and time is of the essence with
respect to each condition precedent.

         SECTION 5.2. CONDITIONS PRECEDENT TO EACH EXTENSION OF TERMINATION
DATE.

         In the event that the Borrower shall request an extension of the
Termination Date pursuant to Section 2.5, such extension shall take effect only
upon the satisfaction of the following conditions precedent:

         (a) the Borrower shall have paid all fees payable hereunder or payable
under or referenced in Article IV, to the extent then due and payable;

         (b) the Administrative Agent shall have received such other documents
and legal opinions in respect of any aspect or consequence of the transactions
contemplated by Section 2.5 as the Administrative Agent shall reasonably
request, including, without limitation, copies of the

<PAGE>   35
                                                                              30

resolutions, in form and substance satisfactory to the Administrative Agent, of
the directors of the Borrower's general partner authorizing the extension of the
Termination Date; and

         (c) the following statements shall be true on and as of the last day of
the then-current Termination Date:

                  (i) The representations and warranties contained in Article
         VII are correct in all material respects on and as of such date as
         though made on and as of such date (unless they speak to a specified

         SECTION 12.1. REMEDIES UPON EVENT OF DEFAULT.

         (a) DEBTOR RELIEF. Upon the occurrence of an Event of Default under
Section 11.3, the Commitments shall automatically terminate, and the entire
outstanding principal amount of the Borrowings and all other accrued and unpaid
portions of the Obligations shall automatically become due and payable without
any action of any kind whatsoever.

         (b) OTHER EVENTS OF DEFAULT. If any Event of Default has occurred and
is continuing, subject to the terms of Section 13.5(b), the Administrative Agent
shall at the request, or may with the consent, of the Required Lenders, upon
notice to the Borrower, do any one or more of the following: (i) If the maturity
of the Obligations has not already been accelerated under Section 12.1(a),
declare the outstanding principal amount of the Borrowings and all other accrued
and unpaid portion of the Obligations immediately due and payable, whereupon
they shall be due and payable; (ii) terminate the Commitments; (iii) reduce any
claim to judgment and (iv) exercise any and all other legal or equitable Rights
afforded by the Credit Documents, by applicable Legal Requirements, or in
equity.

         (c) OFFSET. If an Event of Default has occurred and is continuing, to
the extent lawful, upon notice to the Borrower, each Lender may exercise the
Rights of offset and banker's lien against each and every account and other
property, or any interest therein, which the Borrower may now or hereafter have
with, or which is now or hereafter in the possession of, such Lender to the
extent of the full amount of the Obligations then matured and owed to that
Lender.

         SECTION 12.2. COMPANY WAIVERS.

         To the extent lawful, the Borrower waives all other 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 all or any part of the Obligations is not affected by any
renewal or extension in the time of payment of all or any part of the
Obligations, by any indulgence, or by any release or change in any security for
the payment of all or any part of the Obligations.

         SECTION 12.3. NOT IN CONTROL.

         Nothing in any Credit Documents gives or may be deemed to give to the
Administrative Agent or any Lender the Right to exercise control over any
Company's Real Property, other assets, affairs or management or to preclude or
interfere with any Company's compliance with any Legal Requirement or require
any act or omission by any Company that may be harmful to

<PAGE>   53
                                                                              48

Persons or property. Any "Material Adverse Event" or other materiality or
substantiality qualifier of any representation, warranty, covenant, agreement or
other provision of any Credit Document is included for credit documentation
purposes only and does not imply or be deemed to mean that the Administrative
Agent or any Lender acquiesces in any non-compliance by any Company with any
Legal Requirement, document, or otherwise or does not expect the Companies to
promptly, diligently and continuously carry out all appropriate removal,
remediation, compliance, closure or other activities required or appropriate in
accordance with all Environmental Laws. The Administrative Agent's and the
Lenders' power is limited to the Rights provided in the Credit Documents. All of
those Rights exist solely (and may be exercised in manner calculated by the
Administrative Agent or the Lenders in their respective good faith business
judgment) to assure payment and performance of the Obligations.

         SECTION 12.4. COURSE OF DEALING.

         The acceptance by the Administrative Agent or the Lenders of any
partial payment on the Obligations is not a waiver of any Event of Default then
existing. No waiver by the Administrative Agent, the Required Lenders or the
Lenders of any Event of Default is a waiver of any other then-existing or
subsequent Event of Default. No delay or omission by the Administrative Agent,
the Required Lenders or the Lenders in exercising any Right under the Credit
Documents impairs that Right or is a waiver thereof or any acquiescence therein,
nor will any single or partial exercise of any Right preclude other or further
exercise thereof or the exercise of any other Right under the Credit Documents
or otherwise.

         SECTION 12.5. CUMULATIVE RIGHTS.

         SECTION 12.8. LIMITATION OF LIABILITY.

         Neither the Administrative Agent nor any Lender shall be liable to any
Company for any amounts representing indirect, special or consequential damages

                                  ARTICLE XIII
                        ADMINISTRATIVE AGENT AND LENDERS

         SECTION 13.1. THE ADMINISTRATIVE AGENT.

         (a) APPOINTMENT. Each Lender appoints the Administrative Agent
(including, without limitation, each successor Administrative Agent in
accordance with this Section 13.1) as its nominee and agent to act in its name
and on its behalf (and the Administrative Agent and each such successor accepts
that appointment): (i) To act as its nominee and on its behalf in and under all
Credit Documents; (ii) to arrange the means whereby its funds are to be made
available to the Borrower under the Credit Documents; (iii) to take any action
that it properly requests under the Credit Documents (subject to the concurrence
of other Lenders as may be required under the Credit Documents); (iv) to receive
all documents and items to be furnished to it under the Credit Documents; (v) to
be the secured party, mortgagee, beneficiary, recipient and similar party in
respect of any collateral for the benefit of the Lenders (at any time an Event
of Default or Potential Default has occurred and is continuing); (vi) to
promptly distribute to it all material information, requests, documents and
items received from any Company under the Credit Documents; (vii) to promptly
distribute to it its ratable part of each payment or prepayment (whether
voluntary, as proceeds of collateral upon or after foreclosure, as proceeds of
insurance thereon or otherwise) in accordance with the terms of the Credit
Documents; and (viii) to deliver to the appropriate Persons requests, demands,
approvals and consents received from it. The Administrative Agent, however, may
not be required to take any action that exposes it to personal liability or that
is contrary to any Credit Document or applicable Legal Requirement.

         (b) SUCCESSOR. The Administrative Agent may, subject (at any time no
Event of Default or Potential Default has occurred and is continuing) to the
Borrower's prior written consent that may not be unreasonably withheld, assign
all of its Rights and obligations as the Administrative Agent under the Credit
Documents to any of its Affiliates, which Affiliate shall then be the successor
Administrative Agent under the Credit Documents. The Administrative Agent may
also, upon 30 days' prior notice to the Borrower, voluntarily resign. If the
initial or any successor Administrative Agent ever ceases to be a party to this
Agreement or if the initial or any successor Administrative Agent ever resigns,
then the Required Lenders shall (which, if no Event of Default or Potential
Default has occurred and is continuing, is subject to the Borrower's approval
that may not be unreasonably withheld) appoint the successor Administrative
Agent from among the Lenders (other than the resigning Administrative Agent). If
the Required Lenders fail to appoint a successor Administrative Agent within 30
days after the resigning Administrative Agent has given notice of resignation,
then the resigning Administrative Agent may, on behalf of the Lenders, upon 30
days prior notice to the Borrower, appoint a successor

<PAGE>   55
                                                                              50

Administrative Agent, subject (at any time no Event of Default or Potential
Default has occurred and is continuing) to the Borrower's prior written consent
that may not be unreasonably withheld, which must be a commercial bank having a
combined capital and surplus of at least $1,000,000,000 (as shown on its most
recently published statement of condition). Upon its acceptance of appointment
as successor Administrative Agent, the successor Administrative Agent shall
succeed to and become vested with all of the Rights of the prior Administrative
Agent, and the prior Administrative Agent shall be discharged from its duties
and obligations as Administrative Agent under the Credit Documents, and each
Lender shall execute the documents that any Lender, the resigning Administrative
Agent or the successor Administrative Agent reasonably requests to reflect the
change. After any Administrative Agent's resignation as the Administrative Agent
under the Credit Documents, the provisions of this section inure to its benefit
as to any actions taken or not taken by it while it was the Administrative Agent
under the Credit Documents.

         (c) RIGHTS AS LENDER. The Administrative Agent, in its capacity as a
Lender, has the same Rights under the Credit Documents as any other Lender and
may exercise those Rights as if it were not acting as the Administrative Agent.
The Administrative Agent's resignation or removal does not impair or otherwise
affect any Rights that it has or may have in its capacity as an individual
Lender. Each Lender and the Borrower agree that the Administrative Agent is not
a fiduciary for the Lenders or the Borrower but is simply acting in the capacity
described in this Agreement to alleviate administrative burdens for the Borrower
and the Lenders, that the Administrative Agent has no duties or responsibilities
to the Lenders or the Borrower except those expressly set forth in the Credit
Documents, and that the Administrative Agent in its capacity as a Lender has the
same Rights as any other Lender.

         (d) OTHER ACTIVITIES. The Administrative Agent or any Lender may now or
in the future be engaged in one or more loan, letter of credit, leasing or other
financing transactions with the Borrower, act as trustee or depositary for the
Borrower or otherwise be engaged in other transactions with the Borrower
(collectively, the "other activities") not the subject of the Credit Documents.
Without limiting the Rights of the Lenders specifically set forth in the Credit
Documents, neither the Administrative Agent nor any Lender is responsible to
account to the other Lenders for those other activities, and no Lender shall
have any interest in any other Lender's activities, any present or future
guaranties by or for the account of the Borrower that are not contemplated by or
included in the Credit Documents, any present or future offset exercised by the
Administrative Agent or any Lender in respect of those other activities, any
present or future property taken as security for any of those other activities
or any property now or hereafter in the Administrative Agent's or any other
Lender's possession or control that may be or become security for the
obligations of the Borrower arising under the Credit Documents by reason of the
general description of indebtedness secured or of property contained in any
other agreements, documents or instruments related to any of those other
activities (but, if any payments in respect of those guaranties or that property
or the proceeds thereof is applied by the Administrative Agent or any Lender to
reduce the Obligations, then each Lender is entitled to share in the application
as provided in the Credit Documents).

<PAGE>   56
                                                                              51

         SECTION 13.2. EXPENSES.

         Each Lender shall pay its Commitment Percentage of any reasonable
expenses (including court costs, reasonable attorneys' fees and other costs of
collection) incurred by the Administrative Agent or in connection with any of
the Credit Documents if the Administrative Agent is not reimbursed from other
sources within 30 days after incurrence. Each Lender is entitled to receive its
Commitment Percentage of any reimbursement that it makes to the Administrative
Agent if the Administrative Agent is subsequently reimbursed from other sources.

         SECTION 13.3. PROPORTIONATE ABSORPTION OF LOSSES.

         Except as otherwise provided in the Credit Documents, nothing in the
Credit Documents gives any Lender any advantage over any other Lender insofar as
the Obligations are concerned or relieves any Lender from ratably absorbing any
losses sustained with respect to the Obligations (except to the extent
unilateral actions or inactions by any Lender result in the Borrower or any
other obligor on the Obligations having any credit, allowance, setoff, defense
or counterclaim solely with respect to all or any part of that Lender's part of
the Obligations).

         SECTION 13.4. DELEGATION OF DUTIES; RELIANCE.

         The Lenders may perform any of their duties or exercise any of their
Rights under the Credit Documents by or through the Administrative Agent, and
the Lenders and the Administrative Agent may perform any of their duties or
exercise any of their Rights under the Credit Documents by or through their
respective Representatives. The Administrative Agent, the Lenders and their
respective Representatives (a) are entitled to rely upon (and shall be protected
in relying upon) any written or oral statement believed by it or them to be
genuine and correct and to have been signed or made by the proper Person and,
with respect to legal matters, upon opinion of counsel selected by the
Administrative Agent or that Lender (but nothing in this clause (a) permits the
Administrative Agent to rely on (i) oral statements if a writing is required by
this Agreement or (ii) any other writing if a specific writing is required by
this Agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the Obligations for all purposes until written notice
of the assignment or transfer is given to and received by the Administrative
Agent (and any request, authorization, consent or approval of any Lender is
conclusive and binding on each subsequent holder, assignee or transferee of or
Participant in that Lender's portion of the Obligations until that notice is
given and received), (c) are not deemed to have notice of the occurrence of an
Event of Default unless a responsible officer of the Administrative Agent, who
handles matters associated with the Credit Documents and transactions
thereunder, has actual knowledge or the Administrative Agent has been notified
by a Lender or the Borrower, and (d) are entitled to consult with legal counsel
(including counsel for the Borrower), independent accountants, and other experts
selected by the Administrative Agent and are not liable for any action taken or
not taken in good faith by it in accordance with the advice of counsel,
accountants or experts.

<PAGE>   57
                                                                              52

         SECTION 13.5. LIMITATION OF THE ADMINISTRATIVE AGENT'S LIABILITY.

         (a) EXCULPATION. Neither the Administrative Agent nor any of its
Affiliates or Representatives will be liable to any Lender for any action taken
or omitted to be taken by it or them under the Credit Documents in good faith
and believed by it to be within the discretion or power conferred upon it or
them by the Credit Documents or be responsible for the consequences of any error
of judgment (except for gross negligence or willful misconduct), and neither the
Administrative Agent nor any of its Affiliates or Representatives has a
fiduciary relationship with any Lender by virtue of the Credit Documents (but
nothing in this Agreement negates the obligation of the Administrative Agent to
account for funds received by it for the account of any Lender).

         (b) INDEMNITY. Unless indemnified to its satisfaction against loss,
cost, liability and expense, the Administrative Agent may not be compelled to do
any act under the Credit Documents or to take any action toward the execution or
enforcement of the powers thereby created or to prosecute or defend any suit in
respect of the Credit Documents. If the Administrative Agent requests
instructions from the Lenders or the Required Lenders, as the case may be, with
respect to any act or action in connection with any Credit Document, the
Administrative Agent is entitled to refrain (without incurring any liability to
any Person by so refraining) from that act or action unless and until it has
received instructions. In no event, however, may the Administrative Agent or any
of its Representatives be required to take any action that it or they determine
could incur for it or them criminal or onerous civil liability. Without limiting
the generality of the foregoing, no Lender has any right of action against the
Administrative Agent as a result of the Administrative Agent's acting or
refraining from acting under this Agreement in accordance with instructions of
the Required Lenders.

         (c) RELIANCE. The Administrative Agent is not responsible to any Lender
or any Participant for, and each Lender represents and warrants that it has not
relied upon the Administrative Agent in respect of, (i) the creditworthiness of
any Company and the risks involved to such Lender, (ii) the effectiveness,
enforceability, genuineness, validity or the due execution of any Credit
Document, (iii) any representation, warranty, document, certificate, report or
statement made therein or furnished thereunder or in connection therewith, (iv)
the adequacy of any collateral now or hereafter securing the Obligations or the
existence, priority or perfection of any Lien now or hereafter granted or
purported to be granted on the collateral under any Credit Document, or (v)
observation of or compliance with any of the terms, covenants or conditions of
any Credit Document on the part of the General Partner or any Company. EACH
LENDER AGREES TO INDEMNIFY THE ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES AND
HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S COMMITMENT
PERCENTAGE OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES AND REASONABLE
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED ON, ASSERTED
AGAINST OR INCURRED BY THEM IN ANY WAY RELATING TO OR ARISING OUT OF THE CREDIT
DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE CREDIT DOCUMENTS IF
THE ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH
AMOUNTS BY ANY COMPANY. ALTHOUGH THE

<PAGE>   58
                                                                              53

ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED
UNDER THIS AGREEMENT BY THE LENDERS FOR ITS OR THEIR OWN ORDINARY NEGLIGENCE,
THE ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES DO NOT HAVE THE RIGHT TO BE
INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.

         SECTION 13.6. EVENT OF DEFAULT.

         If an Event of Default has occurred and is continuing, the Lenders
agree to promptly confer in order that the Required Lenders or the Lenders, as
the case may be, may agree upon a course of action for the enforcement of the
Rights of the Lenders. The Administrative Agent is entitled to act or refrain
from taking any action (without incurring any liability to any Person for so
acting or refraining) unless and until it has received instructions from the
Required Lenders. In actions with respect to any Company's property, the
Administrative Agent is acting for the ratable benefit of each Lender.

         SECTION 13.7. LIMITATION OF LIABILITY.

         No Lender or any Participant will incur any liability to any other
Lender or Participant except for acts or omissions in bad faith, and neither the
Administrative Agent nor any Lender or Participant will incur any liability to
any other Person for any act or omission of any other Lender or any Participant.

         SECTION 13.8. OTHER AGENTS.

         SunTrust Equitable Securities Corporation is named on the cover page as
"Sole Lead Arranger" but does not, in such capacity, and nor do the entities
listed as "Co-Syndication Agents" or "Co-Documentation Agents", assume any
responsibility or obligation under this Agreement for syndication,
documentation, servicing, enforcement or collection of any part of the
Obligations, nor any other duties, as agent for the Lenders.

         SECTION 13.9. RELATIONSHIP OF LENDERS.

         The Credit Documents do not create a partnership or joint venture among
the Administrative Agent and the Lenders or among the Lenders.

         SECTION 13.10. BENEFITS OF AGREEMENT.

         None of the provisions of this Article XIII inure to the benefit of any
Company or any other Person except the Administrative Agent and the Lenders.
Therefore, no Company or any other Person is responsible or liable for, entitled
to rely upon or entitled to raise as a defense, in any manner whatsoever, the
failure of the Administrative Agent or any Lender to comply with these
provisions.

                                  MISCELLANEOUS

         SECTION 14.1. NONBUSINESS DAYS.

         Any payment or action that is due under any Credit Document on a
non-Business Day may be delayed until the next succeeding Business Day (but
interest accrues on any payment until it is made). If, however, the payment
concerns a LIBOR Rate Borrowing and if the next succeeding Business Day is in
the next calendar month, then that payment must be made on the next preceding
Business Day.

         SECTION 14.2. COMMUNICATIONS.

         Unless otherwise specified, any communication from one party to another
under any Credit Document must be in writing (which may be by fax) to be
effective and will be deemed to have been given (a) if by fax, when transmitted
to the appropriate fax number (which, without affecting the date when deemed
given, must be promptly confirmed by telephone) or (b) if by any other means,
when actually delivered; provided, further, that any such communication to a
Company from any Person that is not a Company shall be deemed made to that
Company only if it is sent to the Borrower or, if other than the Borrower, to
such Company in care of the Borrower. Until changed by notice under this
Agreement, the address, fax number and telephone number for the Borrower and the
Administrative Agent are stated beside their respective signatures to this
Agreement and for each Lender are stated beside its name on Schedule 2.

         SECTION 14.3. FORM AND NUMBER.

         The form, substance and number of counterparts of each writing to be
furnished under this Agreement must be satisfactory to the Administrative Agent
and the Borrower.

         SECTION 14.4. EXCEPTIONS.

         An exception to any Credit Document covenant or agreement does not
permit violation of any other Credit Document covenant or agreement.

         SECTION 14.5. SURVIVAL.

         All Credit Document provisions survive all closings and are not
affected by any investigation by any party.

         SECTION 14.6. GOVERNING LAW.

         Unless otherwise specified, each Credit Document shall be governed by,
and construed in accordance with, the law of the State of New York and the
United States of America.

         SECTION 14.7. INVALID PROVISIONS.

         If any provision of a Credit Document is judicially determined to be
unenforceable, then all other provisions of it remain enforceable. If the
provision determined to be unenforceable is a

<PAGE>   60
                                                                              55

material part of that Credit Document, then, to the extent lawful, it shall be
replaced by a judicially-construed provision that is enforceable but otherwise
as similar in substance and content to the original provision as the context of
it reasonably allows.

         SECTION 14.8. AMENDMENTS, SUPPLEMENTS, WAIVERS, CONSENTS AND CONFLICTS.

         (a) ALL LENDERS. Any amendment or supplement to, or waiver or consent
under, any Credit Document that purports to accomplish any of the following must
be by a writing executed by the Borrower and executed (or approved in writing,
as the case may be) by all the Lenders: (i) extends the due date for, decreases
the amount or rate of calculation of or waives the late or non-payment of, any
scheduled payment or mandatory prepayment of principal or interest of any of the
Obligations or any fees payable ratably to the Lenders under the Credit
Documents, except, in each case, any adjustments or reductions that are
contemplated by any Credit Document; (ii) changes the definition of
"Commitment", "Commitment Percentage", "Default Percentage" or "Required
Lenders", (iii) increases any part of any Lender's Commitment; (iv) fully or
partially releases or amends any Guaranty, except, in each case, as expressly
provided by any Credit Document or as a result of a merger, consolidation or
dissolution expressly permitted in the Credit Documents; (v) consents to any
assignment by the Borrower under Section 14.10(a); or (vi) changes this clause
(a) or any other matter specifically requiring the consent of all the Lenders
under any Credit Document.

         (b) THE ADMINISTRATIVE AGENT. Any amendment or supplement to, or waiver
or consent under, any Credit Document that purports to accomplish any of the
following must be by a writing executed by the Borrower and executed (or
approved in writing, as the case may be) by the Administrative Agent: (i)
extends the due date for, decreases the amount or rate of calculation of, or
waives the late or non-payment of, any fees payable to the Administrative Agent
under any Credit Document, except, in each case, any adjustments or reductions
that are contemplated by any Credit Document; (ii) increases the Administrative
Agent's obligations beyond its agreements under any Credit Document; or (iii)
changes this clause (b) or any other matter specifically requiring the consent
of the Administrative Agent under any Credit Document.

         (c) THE REQUIRED LENDERS. Except as specified above (i) the provisions
of this Agreement may be amended and supplemented, and waivers and consents
under it may be given, in writing executed by the Borrower, the Required Lenders
and the Administrative Agent, if applicable, and otherwise supplemented only by
documents delivered in accordance with the express terms of this Agreement, and
(ii) each other Credit Document may only be amended and supplemented, and
waivers and consents under it may be given, in a writing executed by the parties
to that Credit Document that is also executed or approved by the Required
Lenders and the Administrative Agent, if applicable, and otherwise supplemented
only by documents delivered in accordance with the express terms of that other
Credit Document.

         (d) WAIVERS. No course of dealing or any failure or delay by the
Administrative Agent, any Lender or any of their respective Representatives with
respect to exercising any Right of the Administrative Agent or any Lender under
any Credit Document operates as a waiver of that Right. A waiver must be in
writing and signed by the parties otherwise required by this

<PAGE>   61
                                                                              56

Section 14.8 to be effective and will be effective only in the specific instance
and for the specific purpose for which it is given.

         (e) CONFLICTS. Although this Agreement and other Credit Documents may
contain additional and different terms and provisions, any conflict or ambiguity
between the express terms and provisions of this Agreement and express terms and
provisions in any other Credit Document is controlled by the express terms and
provisions of this Agreement.

         SECTION 14.9. COUNTERPARTS.

         Any Credit Document may be executed in a number of identical
counterparts (including, at the Administrative Agent's discretion, counterparts
or signature pages executed and transmitted by fax) with the same effect as if
all signatories had signed the same document. All counterparts must be construed
together to constitute one and the same instrument. Certain parties to this
Agreement may execute multiple signature pages to this Agreement as well as one
or more complete counterparts of it, and the Borrower and the Administrative
Agent are authorized to execute, where applicable, those separate signature
pages and insert them, along with signature pages of other parties to this
Agreement, into one or more complete counterparts of this Agreement that contain
signatures of all parties to it.

         SECTION 14.10. PARTIES.

         (a) PARTIES AND BENEFICIARIES. Each Credit Document binds and inures to
the parties to it and each of their respective successors and permitted assigns.
Only those Persons may rely upon or raise any defense about this Agreement. No
Company may assign or transfer any Rights or obligations under any Credit
Document without first obtaining the consent of all the Lenders and any
purported assignment or transfer without the consent of all the Lenders.

         (b) RELATIONSHIP OF PARTIES. The relationship between (x) each Lender
and (y) each Company is that of creditor/secured party and obligor,
respectively. Financial covenant and reporting provisions in the Credit
Documents are intended solely for the benefit of each Lender to protect its
interest as a creditor/secured party. Nothing in the Credit Documents may be
construed as (i) permitting or obligating any Lender to act as a financial or
business advisor or consultant to any Company, (ii) permitting or obligating any
Lender to control any Company or conduct its operations, (iii) creating any
fiduciary obligation of any Lender to any Company, or (iv) creating any joint
venture, agency or other relationship between the parties except as expressly
specified in the Credit Documents.

         (c) PARTICIPATIONS. Any Lender may (subject to the provisions of this
section, in accordance with applicable Legal Requirement, in the ordinary course
of its business, at any time, and with notice to the Borrower) sell to one or
more Persons (each a "PARTICIPANT") participating interests in its portion of
the Obligations so long as the minimum amount of such participating interest is
$5,000,000. The selling Lender remains a "Lender" under the Credit Documents,
the Participant does not become a "Lender" under the Credit Documents, and the
selling Lender's obligations under the Credit Documents remain unchanged. The
selling Lender remains solely responsible for the performance of its obligations
and remains the holder of its share of the Borrowings for all purposes under the
Credit Documents. The Borrower and the

<PAGE>   62
                                                                              57

Administrative Agent shall continue to deal solely and directly with the selling
Lender in connection with that Lender's Rights and obligations under the Credit
Documents, and each Lender must retain the sole right and responsibility to
enforce due obligations of the Companies. Participants have no Rights under the
Credit Documents except as provided in the except clause of the last sentence of
this Section 14.10(c). Subject to the following, each Lender may obtain (on
behalf of its Participants) the benefits of Article 3 with respect to all
participations in its part of the Obligations outstanding from time to time so
long as the Borrower is not obligated to pay any amount in excess of the amount
that would be due to that Lender under Article 3 calculated as though no
participations have been made. No Lender may sell any participating interest
under which the Participant has any Rights to approve any amendment,
modification or waiver of any Credit Document except as to matters in Section
14.8(a)(i) and (ii).

         (d) ASSIGNMENTS. Each Lender may make assignments to any Federal
Reserve Bank, provided that any related costs, fees and expenses incurred by
such Lender in connection with such assignment or the re-assignment back to it
free of any interests of the Federal Reserve Bank, shall be for the sole account
of Lender. Each Lender may also assign to one or more assignees (each an
"ASSIGNEE") all or any part of its Rights and obligations under the Credit
Documents so long as (i) the assignor Lender and Assignee execute and deliver to
the Administrative Agent and the Borrower for their consent and acceptance (that
may not be unreasonably withheld in any instance and is not required by the
Borrower if an Event of Default has occurred and is continuing) an assignment
and assumption agreement in substantially the form of Exhibit E (an
"ASSIGNMENT") and pay to the Administrative Agent a processing fee of $1,000
(which payment obligation is the sole liability, joint and several, of that
Lender and Assignee), (ii) the assignment must be for a minimum total Commitment
of $5,000,000, and, if the assignor Lender retains any Commitment, it must be a
minimum total Commitment of $10,000,000, and (iii) the conditions for that
assignment set forth in the applicable Assignment are satisfied. The Effective
Date in each Assignment must (unless a shorter period is agreed to by the
Borrower and the Administrative Agent) be at least five Business Days after it
is executed and delivered by the assignor Lender and the Assignee to the
Administrative Agent and the Borrower for acceptance. Once such Assignment is
accepted by the Administrative Agent and the Borrower, and subject to all of the
following occurring, then, on and after the Effective Date stated in it (A) the

     THIS AGREEMENT (the "First Amendment") is made as of the 2nd day of
February, 2001 by and between PSC Inc., a New York corporation (the "Company")
and the undersigned, an officer of the Company (the "Executive").

     WHEREAS, the Company and Executive entered into an Employment Agreement as
of December 4, 2000 ("Agreement"); and

     WHEREAS, the parties desire to amend in certain respects said Agreement.

     NOW, THEREFORE, in consideration of the premises and of Executive agreeing
to continue to serve as an employee of the Company, the parties hereto agree as
follows:

     1.  All of the terms in this First Amendment shall have the meanings
defined in the Agreement.

     2.  Section 10B of the Agreement is deleted in its entirety and replaced by
a new Section 10B, which will read as follows:

            "10B  Termination of Employment - Change in Control.  In the event
          Executive terminates his employment for any reason within ninety (90)
          days after the occurrence of a Change in Control (as hereinafter
          defined) of the Company or in the event of the termination of
          employment of Executive within the two year period following a Change
          in Control (as hereinafter defined) of the Company, and such
          termination is (i) by the Company or its successor for any reason
          other than Termination for Cause (as hereinafter defined), death or
          disability, or (ii) by the Executive for "Good Reason" (as hereinafter
          defined), the Company or its successor will pay the Executive
          following such termination an amount equal to the product of the sum
          of (x) Executive's Base Salary at the annual rate then in effect in
          addition to (y) the highest annual bonus paid to Executive under the
          Company's current Management Incentive Plan or any successor plan in
          the three full fiscal years preceding termination multiplied by 2.9.
          Said amount shall be payable in the manner elected by Executive from
          one of the following options:  (i) in a lump sum cash payment, or (ii)
          in three equal annual installments commencing on the date of
<PAGE>

          termination, or (iii) in equal bi-weekly installments over a period of
          three years.  In addition, Executive will be immediately vested in any
          retirement, incentive, restricted stock, or option plans or agreements
          then in effect and the Company will continue to provide Executive with
          Executive's then current health, dental, life and accidental death and
          dismemberment insurance benefits for a period of three years.  All
          payments made to Executive hereunder will be subject to all applicable
          employment and withholding taxes."

     3.  Except as modified by this First Amendment, the Agreement has not
heretofore been amended or cancelled, and remains in full force and effect.

     IN WITNESS WHEREOF, Executive has executed this Agreement and the Company
has caused this Agreement to be executed as of the date set forth above.
